The Depositor intends to sell commercial mortgage pass-through certificates (collectively, the “Certificates”), to be issued hereunder in multiple classes (each, a “Class”), which in the aggregate will evidence the entire beneficial ownership interest in the Trust to be created hereunder, the primary assets of which will be a pool of commercial mortgage loans and two separate trust subordinate companion loans interest in related commercial mortgage loans. As provided herein, the Certificate Administrator shall elect or shall cause an election to be made to treat designated portions of the Trust (exclusive of the Excess Interest and the proceeds thereof in the Excess Interest Distribution Account) for federal income tax purposes as four separate real estate mortgage investment conduits (the “Upper-Tier REMIC”, the “Lower-Tier REMIC”, the “Y&L Towers Trust Subordinate Companion Loan REMIC” and the “Standard Highline Trust Subordinate Companion Loan REMIC”, each a “Trust REMIC” as described herein).

In addition, the parties intend that the portions of the issuing entity consisting of the Specific Grantor Trust Assets and the ARD Grantor Trust Assets will be treated as a grantor trust (the “Grantor Trust”) for federal income tax purposes under subpart E, part I of subchapter J of the Code. Each Class of Certificates other than the Class R Certificates will represent undivided beneficial interests in the portion of the Grantor Trust consisting of the Specific Grantor Trust Assets with the corresponding alphabetical or alphanumeric designation.

“Nonrecoverable P&I Advance”: Any P&I Advance previously made or proposed to be made in respect of a Mortgage Loan (including any Non-Serviced Mortgage Loan), Trust Subordinate Companion Loan or REO Loan (including any portion of an REO Loan related to a Trust Subordinate Companion Loan, but excluding any portion of an REO Loan related to any other Companion Loan) which the Master Servicer, in accordance with the Servicing Standard, or the Trustee, in its good faith business judgment, as applicable, determines would not be ultimately recoverable, together with any accrued and unpaid interest thereon at the Reimbursement Rate, from Late Collections or any other recovery on or in respect of such Mortgage Loan, Trust Subordinate Companion Loan or REO Loan; provided, however, that the Special Servicer may, at its option (with respect to any Specially Serviced Loan and prior to the occurrence of a Consultation Termination Event (other than with respect to any applicable Excluded Loan) in consultation with the Directing Certificateholder) make a determination in accordance with the Servicing Standard, that any P&I Advance previously made or proposed to be made is a Nonrecoverable P&I Advance and shall deliver to the Master Servicer (and with respect to a Serviced Mortgage Loan, to any Other Servicer, and, with respect to a Non-Serviced Mortgage Loan, to the related Non-Serviced Master Servicer and Non-Serviced Special Servicer), the Certificate Administrator, the Trustee, the Operating Advisor and the 17g-5 Information Provider notice of such determination. Any such determination may be conclusively relied upon by, and shall be binding upon, the Master Servicer and the Trustee, provided, however, that the Special Servicer shall not have such obligation to make an affirmative determination that any P&I Advance is or would be recoverable and in the absence of a determination by the Special Servicer that such P&I Advance is or would be a Nonrecoverable P&I Advance, such decision shall remain with the Master Servicer or Trustee, as applicable. If the Special Servicer makes a determination that only a portion, and not all, of any previously made or proposed P&I Advance is a Nonrecoverable P&I Advance, the Master Servicer and the Trustee shall have the right to make its own subsequent determination that any remaining portion of any such previously made or proposed P&I Advance is a Nonrecoverable P&I Advance. With respect to any Non-Serviced Whole Loan, if any Non-Serviced Master Servicer or Non-Serviced Special Servicer, as applicable, in connection with a securitization of the related Non-Serviced Companion Loan determines that a principal and interest advance with respect to the related Non-Serviced Companion Loan, if made, would be a “nonrecoverable P&I advance”, such determination shall not be binding on the Master Servicer and the Trustee as it relates to any proposed P&I Advance with respect to the related Non-Serviced Mortgage Loan. Similarly, with respect to the related Non-Serviced Mortgage Loan, if the Master Servicer, the Special Servicer or the Trustee, as applicable, determines that any P&I Advance with respect to a related Non-Serviced Mortgage Loan, if made, would be a Nonrecoverable P&I Advance, such determination shall not be binding on the related Non-Serviced Master Servicer and related Non-Serviced Trustee as it relates to any proposed P&I Advance with respect to the related Non-Serviced Companion Loan (unless the related Non-Serviced PSA provides otherwise). In making such recoverability determination, the Master Servicer, the Special Servicer or the Trustee, as applicable, will be entitled (a) to consider (among other things) (i) the obligations of the Mortgagor under the terms of the related Mortgage Loan or Companion Loan as it may have

 -100-

been modified and (ii) the related Mortgaged Properties in their “as-is” or then-current conditions and occupancies, as modified by such party’s assumptions (consistent with the Servicing Standard in the case of the Master Servicer or the Special Servicer or in its good faith business judgment in the case of the Trustee, solely in its capacity as Trustee) regarding the possibility and effects of future adverse changes with respect to such Mortgaged Properties, (b) to estimate and consider (among other things) future expenses, (c) to estimate and consider (consistent with the Servicing Standard in the case of the Master Servicer and the Special Servicer or in its good faith business judgment in the case of the Trustee, solely in its capacity as Trustee) (among other things) the timing of recoveries, and (d) to give due regard to the existence of any Nonrecoverable Advances which, at the time of such consideration, the recovery of which are being deferred or delayed by the Master Servicer or the Trustee because there is insufficient principal available for such recovery, in light of the fact that related proceeds are a source of recovery not only for the Advance under consideration but also a potential source of recovery for such delayed or deferred Advance. In addition, any Person, in considering whether a P&I Advance is a Nonrecoverable Advance, will be entitled to give due regard to the existence of any outstanding Nonrecoverable Advance or Workout-Delayed Reimbursement Amount with respect to other Mortgage Loans, the Y&L Towers Trust Subordinate Companion Loan or the Standard Highline Trust Subordinate Companion Loan, the reimbursement of which, at the time of such consideration, is being deferred or delayed by the Master Servicer or the Trustee because there is insufficient principal available for such reimbursement, in light of the fact that proceeds on the related Mortgage Loan or Trust Subordinate Companion Loan, as the case may be, are a source of reimbursement not only for the P&I Advance under consideration, but also as a potential source of reimbursement of such Nonrecoverable Advance or Workout-Delayed Reimbursement Amounts which are or may be being deferred or delayed. In addition, any such Person may update or change its recoverability determinations at any time (but not reverse any other Person’s determination that an Advance is a Nonrecoverable Advance) and, consistent with the Servicing Standard, in the case of the Master Servicer or in its good faith business judgment in the case of the Trustee (solely in its capacity as Trustee), may obtain at the expense of the Trust any reasonably required analysis, Appraisals or market value estimates or other information for making a recoverability determination.

The Officer’s

 -101-

Certificate shall set forth such determination of nonrecoverability and the considerations of the Master Servicer, the Special Servicer or the Trustee, as applicable, forming the basis of such determination (which shall be accompanied by, to the extent available, income and expense statements, rent rolls, occupancy status, property inspections and any other information used by the Master Servicer, the Special Servicer or the Trustee, as applicable, to make such determination and shall include any existing Appraisal of the related Mortgaged Property). The Trustee shall be entitled to conclusively rely on the Master Servicer’s or Special Servicer’s determination that a P&I Advance is or would be nonrecoverable, and the Master Servicer shall be entitled to conclusively rely on the Special Servicer’s determination that a P&I Advance is or would be nonrecoverable, which determination shall be binding on the Master Servicer and the Trustee. In the case of a cross-collateralized Mortgage Loan (if any), such recoverability determination shall take into account the cross-collateralization of the related cross-collateralized Mortgage Loan.

“Nonrecoverable Servicing Advance”: Any Servicing Advance previously made or proposed to be made in respect of a Mortgage Loan (other than a Non-Serviced Mortgage Loan), Whole Loan or REO Property which the Master Servicer, the Special Servicer, in each case in accordance with the Servicing Standard, or the Trustee, in its good faith business judgment, as applicable, determines would not be ultimately recoverable, together with any accrued and unpaid interest thereon, at the Reimbursement Rate, from Late Collections or any other recovery on or in respect of such Mortgage Loan, Whole Loan or REO Property. In making such recoverability determination, such Person will be entitled (a) to consider (among other things) (i) the obligations of the Mortgagor under the terms of the related Mortgage Loan or Companion Loan, as applicable, as it may have been modified and (ii) the related Mortgaged Properties in their “as-is” or then-current conditions and occupancies, as modified by such party’s assumptions (consistent with the Servicing Standard in the case of the Master Servicer or the Special Servicer or in its good faith business judgment in the case of the Trustee, solely in its capacity as Trustee) regarding the possibility and effects of future adverse change with respect to such Mortgaged Properties, (b) to estimate and consider (among other things) future expenses, (c) to estimate and consider (consistent with the Servicing Standard in the case of the Master Servicer or the Special Servicer or in its good faith business judgment in the case of the Trustee, solely in its capacity as Trustee) (among other things) the timing of recoveries and (d) give due regard to the existence of any Nonrecoverable Advances that, at the time of such consideration, the recovery of which are being deferred or delayed by the Master Servicer or the Trustee because there is insufficient principal available for such reimbursement, in light of the fact that Related Proceeds are a source of recovery not only for the Advance under consideration but also a potential source of recovery for such delayed or deferred Advance. In addition, any Person, in considering whether a Servicing Advance is a Nonrecoverable Servicing Advance, will be entitled to give due regard to the existence of any Nonrecoverable Advance or Workout-Delayed Reimbursement Amounts with respect to other Mortgage Loans, the reimbursement of which, at the time of such consideration, is being deferred or delayed by the Master Servicer, in light of the fact that proceeds on the related Mortgage Loan are a source of recovery not only for the Servicing Advance under consideration, but also as a potential source of recovery of such Nonrecoverable Advance or Workout-Delayed Reimbursement Amounts which are or may be being deferred or delayed; provided, however, that if the Workout-Delayed Reimbursement Amount relates to a Servicing Advance for the Yorkshire & Lexington Towers Whole Loan or The Standard Highline NYC Whole Loan, the Master Servicer will be entitled to recover such

 -102-

Workout-Delayed Reimbursement Amount from general collections on deposit in the Collection Account for the mortgage pool including the related Yorkshire & Lexington Towers Mortgage Loan or The Standard Highline NYC Mortgage Loan. In addition, any such Person may update or change its recoverability determinations at any time (but not reverse any other Person’s determination that an Advance is a Nonrecoverable Advance) and, consistent with the Servicing Standard, in the case of the Master Servicer or in its good faith business judgment in the case of the Trustee (solely in its capacity as Trustee), may obtain at the expense of the Trust any reasonably required analysis, Appraisals or market value estimates or other information for making a recoverability determination. The determination by the Master Servicer, the Special Servicer or the Trustee, as the case may be, that it has made a Nonrecoverable Servicing Advance or that any proposed Servicing Advance, if made, would constitute a Nonrecoverable Servicing Advance, or any updated or changed recoverability determination, shall be evidenced by an Officer’s Certificate delivered by either of the Special Servicer or the Master Servicer to the other and to the Trustee, the Certificate Administrator, the Directing Certificateholder (but in the case of the Directing Certificateholder, only prior to the occurrence and continuance of a Consultation Termination Event and only with respect to any Mortgage Loan or Trust Subordinate Companion Loan other than an Excluded Loan as to such party) (and in the case of a Serviced Mortgage Loan or Non-Serviced Mortgage Loan, any Other Servicer or Non-Serviced Master Servicer, as applicable), the Operating Advisor (but only in the case of the Special Servicer) and the Depositor, or by the Trustee to the Depositor, the Master Servicer, the Special Servicer, the Operating Advisor and the Certificate Administrator (and in the case of a Serviced Mortgage Loan or Non-Serviced Mortgage Loan, any Other Servicer or Non-Serviced Master Servicer, as applicable); provided, however, that the Special Servicer may, at its option (with respect to any Specially Serviced Loan and prior to the occurrence of a Consultation Termination Event (other than with respect to any applicable Excluded Loan) in consultation with the Directing Certificateholder), make a determination in accordance with the Servicing Standard, that any Servicing Advance previously made or proposed to be made is a Nonrecoverable Servicing Advance and shall deliver to the Master Servicer (and with respect to a Serviced Mortgage Loan, to any Other Servicer), the Trustee, the Operating Advisor, the Certificate Administrator and the 17g-5 Information Provider notice of such determination. Any such determination may be conclusively relied upon by, and shall be binding upon, the Master Servicer, the Special Servicer and the Trustee, provided, however, that the Special Servicer shall not have such obligation to make an affirmative determination that any Servicing Advance is or would be recoverable and in the absence of a determination by the Special Servicer that such Servicing Advance is or would be a Nonrecoverable Servicing Advance, such decision shall remain with the Master Servicer or the Trustee, as applicable. If the Special Servicer makes a determination that only a portion, and not all, of any previously made or proposed Servicing Advance is a Nonrecoverable Servicing Advance, the Master Servicer and the Trustee shall each have the right to make its own subsequent determination that any remaining portion of any such previously made or proposed Servicing Advance is a Nonrecoverable Servicing Advance. The Officer’s Certificate shall set forth such determination of nonrecoverability and the considerations of the Master Servicer, the Special Servicer or the Trustee, as applicable, forming the basis of such determination (which shall be accompanied by, to the extent available, related income and expense statements, rent rolls, occupancy status and property inspections, and shall include any existing Appraisal with respect to the related Mortgage Loan or Serviced Companion Loan, as applicable, or related Mortgaged Property). The Special Servicer shall promptly furnish

 -103-

any party required to make Servicing Advances hereunder with any information in its possession regarding the Specially Serviced Loans and REO Properties as such party required to make Servicing Advances may reasonably request for purposes of making recoverability determinations. The Trustee shall be entitled to conclusively rely on the Master Servicer’s or the Special Servicer’s, as the case may be, determination that a Servicing Advance is or would be nonrecoverable, and the Master Servicer shall be entitled to conclusively rely on the Special Servicer’s determination that a Servicing Advance is or would be nonrecoverable. Notwithstanding anything herein to the contrary, if the Special Servicer requests that the Master Servicer make a Servicing Advance, the Master Servicer may conclusively rely on such request as evidence that such advance is not a Nonrecoverable Servicing Advance; provided, however, that the Special Servicer shall not be entitled to make such a request more frequently than once per calendar month with respect to Servicing Advances other than emergency advances (although such request may relate to more than one Servicing Advance). In the case of a cross-collateralized Mortgage Loan (if any), such recoverability determination shall take into account the cross-collateralization of the related cross-collateralized Mortgage Loan. The determination as to the recoverability of any servicing advance previously made or proposed to be made in respect of a Non-Serviced Whole Loan shall be made by the related Non-Serviced Master Servicer, Non-Serviced Special Servicer or Non-Serviced Trustee, as the case may be, pursuant to the Non-Serviced PSA.

(c)       Pursuant to each Mortgage Loan Purchase Agreement, except in the case of a Non-Serviced Mortgage Loan, the related Mortgage Loan Seller is required at its sole cost and expense, to itself, or to engage a third party to, put each Assignment of Mortgage, each assignment of Assignment of Leases and each assignment of each UCC Financing Statement (collectively, the “Assignments” and, individually, “Assignment”) relating to the Mortgage Loans and Trust Subordinate Companion Loans conveyed by it under the applicable Mortgage Loan Purchase Agreement in proper form for filing or recording, as applicable, and to submit such Assignments for filing or recording, as the case may be, in the applicable public filing or recording office. On the Closing Date, the Mortgage Loan Sellers may deliver one (1) omnibus assignment for all such Mortgage Loans substantially in the form of Exhibit H hereto to the Custodian as provided in Section 2.01(b). Except under the circumstances provided for in the last sentence of this subsection (c) and except in the case of a Non-Serviced Mortgage Loan, the related Mortgage Loan Seller will itself, or a third party at such Mortgage Loan Seller’s expense will, promptly (and in any event within one hundred-twenty (120) days after the later of the Closing Date and the related Mortgage Loan Seller’s actual receipt of the related documents and the necessary recording and filing information) cause to be submitted for recording or filing, as the case may be, in the appropriate public office for real property records or UCC Financing Statements, as appropriate, each Assignment. Each such Assignment submitted for recording shall reflect that it (or a file copy thereof in the case of a UCC Assignment) should be returned by the public recording office to the Custodian or its designee following recording or filing (or to the related Mortgage Loan Seller or its agent who will then be responsible for delivery of the same to the Custodian or its designee). Any such Assignment received by the Custodian shall be promptly included in the related Mortgage File and be deemed a part thereof, and any such Assignment received by the related Mortgage Loan Seller or its agent shall be required to be delivered to the Custodian to be included as part of the related Mortgage File within thirty (30) days after receipt. If any such document or instrument is determined to be incomplete or not to meet the recording or filing requirements of the jurisdiction in which it is to be recorded or filed, or is lost by the public office or returned unrecorded or unfiled, as the case may be, because of a defect therein, on or about one hundred-eighty (180) days after the Closing Date, the related Mortgage Loan Seller or its designee shall prepare, at its own expense, a substitute therefor or cure such defect, as the case may be, and thereafter the related Mortgage Loan Seller or its designee shall, at the expense of such Mortgage Loan Seller, upon receipt thereof cause the same to be duly recorded or filed, as appropriate. If, by the first anniversary of the Closing Date, the Custodian has not received confirmation of the recording or filing as the case may be, of any such Assignment, it shall so advise the related Mortgage Loan Seller who may then pursue such confirmation itself or request that the Custodian pursue such confirmation at the related Mortgage Loan Seller’s expense, and upon such a request and provision for payment of such expenses satisfactory to the Custodian, the Custodian, at the expense of the applicable Mortgage Loan Seller, shall cause a search of the land records of each applicable jurisdiction and of the records of the offices of the applicable Secretary of State for confirmation that the Assignment appears in such records and retain a copy of such confirmation in the related Mortgage File. In the event that confirmation of the recording or filing of an Assignment cannot be obtained, the Custodian or the related Mortgage Loan Seller, as applicable, shall promptly inform the other and the Custodian shall provide such Mortgage Loan Seller with a copy of the Assignment and request the preparation of a new Assignment. The related Mortgage Loan Seller shall pay the expenses for the preparation of replacement Assignments for any Assignments which, having

 -180-

been properly submitted for filing or recording to the appropriate governmental office by the Custodian, fail to appear of record and must be resubmitted. Notwithstanding the foregoing, there shall be no requirement to record any assignment to the Trustee referred to in clause (iii) or (v) of the definition of “Mortgage File,” or to file any UCC-3 to the Trustee referred to in clause (ix) of the definition of “Mortgage File,” in those jurisdictions where, in the written opinion of local counsel (which opinion shall be an expense of the related Mortgage Loan Seller) acceptable to the Depositor and the Trustee, such recordation and/or filing is not required to protect the Trustee’s interest in the related Mortgage Loan, against sale, further assignment, satisfaction or discharge by the related Mortgage Loan Seller, the Master Servicer, the Special Servicer, any Sub-Servicer or the Depositor.

(d)       All documents and records in the Depositor’s or the applicable Mortgage Loan Seller’s possession relating to the Mortgage Loans and the Trust Subordinate Companion Loans (including, in each case, financial statements, operating statements and any other information provided by the respective Mortgagor from time to time, but excluding the applicable Mortgage Loan Seller’s internal communications (including such communications between such Mortgage Loan Seller and its Affiliates) and underwriting analysis (including documents prepared by the applicable Mortgage Loan Seller or any of its Affiliates for such purposes), draft documents, attorney-client communications that are privileged communications or constitute legal or other due diligence analyses and credit underwriting or due diligence analyses or data) that (i) are not required to be a part of a Mortgage File in accordance with the definition thereof and (ii) are reasonably necessary for the servicing of each such Mortgage Loan and Trust Subordinate Companion Loan, together with copies of all documents in each Mortgage File, shall be delivered by the Depositor or the applicable Mortgage Loan Seller to the Master Servicer within five (5) Business Days after the Closing Date and shall be held by the Master Servicer on behalf of the Trustee in trust for the benefit of the Certificateholders and, if applicable, on behalf of the related Companion Holder. Such documents and records shall be any documents and records (with the exception of any items excluded under the immediately preceding sentence) that would otherwise be a part of the Servicing File.

(e)       In connection with the Depositor’s assignment pursuant to subsection (a) above, the Depositor shall deliver to the Trustee and the Master Servicer, on or before two (2) Business Days after the Closing Date, a fully executed original counterpart of each of the Mortgage Loan Purchase Agreements, as in full force and effect, without amendment or modification, on the Closing Date.

(f)       The Depositor shall use its reasonable best efforts to require that, promptly after the Closing Date, but in all events within three (3) Business Days after the Closing Date, each of the Mortgage Loan Sellers shall cause all funds on deposit in escrow accounts maintained with respect to the Mortgage Loans transferred by such Mortgage Loan Seller, whether such accounts are held in the name of the applicable Mortgage Loan Seller or any other name to be transferred to the Master Servicer (or a Sub-Servicer) for deposit into Servicing Accounts.

(g)       With respect to the Mortgage Loan secured by the Mortgaged Property identified as “The Boulders Resort & Spa” on the Mortgage Loan Schedule, which is subject to a franchise agreement with a related comfort letter in favor of the respective Mortgage Loan Seller

 -181-

that requires notice to or request of the related franchisor to transfer or assign any related comfort letter to the Trust or otherwise have a new comfort letter issued in the name of the Trust, the related Mortgage Loan Seller or its designee will be required to provide any such required notice or make any such required request to the related franchisor (with a copy of such notice or request to the Master Servicer) within 45 days of the Closing Date (or any shorter period if required by the applicable comfort letter), and the Master Servicer shall use reasonable efforts in accordance with the Servicing Standard to acquire such replacement comfort letter, if necessary (or to acquire any such new document or acknowledgement as may be contemplated under the existing comfort letter). If the Master Servicer is unable to acquire any such replacement comfort letter (or new document or acknowledgement, as applicable) within one hundred twenty (120) days of the Closing Date, the Master Servicer shall notify the related Mortgage Loan Seller that no such replacement comfort letter has been received.

(h)       Each Mortgage Loan Purchase Agreement shall provide that no later than sixty (60) days after the Closing Date, each Mortgage Loan Seller shall deliver or cause to be delivered the Diligence Files for each of its Mortgage Loans and Trust Subordinate Companion Loans to the Depositor by uploading such Diligence Files to the Designated Site. Promptly upon completion of such delivery of the Diligence Files (but in no event later than sixty (60) days after the Closing Date), the applicable Mortgage Loan Seller shall provide to the Depositor a certificate (with a copy (which may be sent by email) to each of the Master Servicer, the Special Servicer, the Trustee, the Certificate Administrator, the Custodian, the Asset Representations Reviewer and the Operating Advisor) certifying that the electronic copies of the Diligence File uploaded to the Designated Site contain all documents and information required under the definition of “Diligence File” and such Diligence Files are organized and categorized in accordance with the electronic file structure reasonably agreed to by the Depositor and the Mortgage Loan Seller (the “Diligence File Certificate”).

(i)       On or before the Closing Date, the Depositor shall deliver the Initial Schedule AL File, any Initial Schedule AL Additional File and Annex A-1 to the Prospectus in EDGAR-Compatible Format and Microsoft Excel format to the Master Servicer at KC_Investor_Reporting@KeyBank.com.

(j)       Notwithstanding anything to the contrary contained in this Section 2.01 or in Section 2.02, in connection with a Servicing Shift Whole Loan, (1) instruments of assignment to the Trustee may be in blank and need not be recorded pursuant to this Agreement (other than the endorsements to the Note(s) evidencing the related Servicing Shift Mortgage Loan) until the earlier of (i) the related Servicing Shift Securitization Date, in which case such instruments shall be assigned and recorded in accordance with the related Non-Serviced PSA, (ii) 180 days following the Closing Date, and (iii) such Servicing Shift Whole Loan becoming a Specially Serviced Loan prior to such Servicing Shift Securitization Date, in which case assignments and recordations shall be effected in accordance with this Section 2.01 until the occurrence, if any, of such Servicing Shift Securitization Date, (2) no letter of credit need be amended (including, without limitation, to change the beneficiary thereon) until the earlier of (i) the related Servicing Shift Securitization Date, in which case such amendment shall be in accordance with the related Non-Serviced PSA, (ii) 180 days following the Closing Date, and (iii) such Servicing Shift Whole Loan becoming a Specially Serviced Loan prior to such Servicing Shift Securitization Date in which case such amendment shall be effected in accordance with the terms of this

 -182-

Section 2.01, and (3) on and following such Servicing Shift Securitization Date, the Person selling the related Servicing Shift Lead Note to the related Non-Serviced Depositor, at its own expense, shall be (a) entitled to direct in writing, via a Request for Release, which may be conclusively relied upon by the Custodian, the Custodian to deliver the originals of all the Mortgage Loan documents relating to such Servicing Shift Whole Loan in its possession (other than the original Note(s) evidencing such Servicing Shift Mortgage Loan) to the related Non-Serviced Trustee or the related Non-Serviced Custodian, (b) if the right under clause (a) is exercised, required to cause the retention by or delivery to the Custodian of photocopies of Mortgage Loan documents related to such Servicing Shift Whole Loan so delivered to such Non-Serviced Trustee or such Non-Serviced Custodian, (c) entitled to cause the completion (or, in the event of a recordation as contemplated by clause (1)(ii) of this paragraph, the preparation, execution and delivery) and recordation of instruments of assignment in the name of the related Other Trustee or related Non-Serviced Custodian, (d) if the right under clause (c) is exercised, required to deliver to the Trustee or Custodian photocopies of any instruments of assignment so completed and recorded, and (e) entitled to require the Master Servicer to transfer, and to cooperate with all reasonable requests in connection with the transfer of, the Servicing File, and any Escrow Payments, reserve funds and items specified in clauses (9), (12) (14) and (18) of the definition of “Mortgage File” for such Servicing Shift Whole Loan to the related Other Servicer.

Section 2.02      Acceptance by Trustee. (a) The Trustee, by the execution and delivery of this Agreement (1) acknowledges receipt by it or a Custodian on its behalf, subject to the provisions of Section 2.01, in good faith and without notice of any adverse claim, of the applicable documents specified in clause (i) of the definition of “Mortgage File” with respect to each Mortgage Loan and Trust Subordinate Companion Loan and of all other assets included in the Trust Fund and (2) declares (a) that it or a Custodian on its behalf holds and will hold such documents and the other documents delivered or caused to be delivered by the Mortgage Loan Sellers that constitute the Mortgage Files in the name of the Trust for the benefit of all present and future Certificateholders, and (b) that it holds and will hold such other assets included in the Trust Fund, in trust for the exclusive use and benefit of all present and future Certificateholders and, with respect to any original document in the Mortgage File for a Serviced Whole Loan, for any present or future Companion Holder (and for the benefit of the Trustee as holder of the Lower-Tier Regular Interests), as applicable. If any Mortgage Loan Seller is unable to deliver or cause the delivery of any original Mortgage Note, such Mortgage Loan Seller may deliver a copy of such Mortgage Note, together with a signed lost note affidavit and appropriate indemnity and shall thereby be deemed to have satisfied the document delivery requirements of Section 2.01 and of this Section 2.02.

(b)       Within sixty (60) days of the Closing Date (or with respect to a Qualified Substitute Mortgage Loan within sixty (60) days after the Due Date in the month of substitution), the Custodian, shall review the Mortgage Loan documents delivered or caused to be delivered by the Mortgage Loan Sellers constituting the Mortgage Files; and, promptly following such review (but in no event later than sixty (60) days after the Closing Date), the Custodian shall, in the form attached as Exhibit Q, certify in writing to each of the Rating Agencies, the Depositor, the Master Servicer, the Special Servicer, the Directing Holder (so long as no Consultation Termination Event shall have occurred and be continuing and only with respect to Mortgage Loans or Trust Subordinate Companion Loans other than any Excluded Loan with respect to the Directing Holder or, if the Directing Holder is the Directing Certificateholder, the Holder of the

 -183-

majority of the Controlling Class), the Operating Advisor, the Asset Representations Reviewer and the applicable Mortgage Loan Seller (as to each Mortgage Loan (or Trust Subordinate Companion Loan) listed in the Mortgage Loan Schedule (other than any Mortgage Loan or Trust Subordinate Companion Loan paid in full)) that, except as specifically identified in any exception report annexed to such writing (the “Custodial Exception Report”), (i) subject to the final proviso of the definition of “Mortgage File” herein and Section 2.01 hereof, all documents specified in clauses (i) through (v), (viii), (ix), (xi), (xii) and (xiii) (or, with respect to clause (xii), a copy of such letter of credit and the required Officer’s Certificate), if any, of the definition of “Mortgage File”, as applicable, are in its possession, (ii) the foregoing documents delivered or caused to be delivered by the Mortgage Loan Sellers have been reviewed by the Custodian and appear regular on their face and appear to be executed and to relate to such Mortgage Loan or Trust Subordinate Companion Loan, and (iii) based on such examination and only as to the foregoing documents, the information set forth in the Mortgage Loan Schedule with respect to the items specified in clauses (iv), (vi) and (viii)(c) in the definition of “Mortgage Loan Schedule” is correct. With respect to each Mortgage Loan or Trust Subordinate Companion Loan listed on the Custodial Exception Report, the Custodian shall specifically identify such Mortgage Loan or Trust Subordinate Companion Loan together with the nature of such exception (in the form reasonably acceptable to the Custodian and the related Mortgage Loan Seller and separating items required to be in the Mortgage File but never delivered from items which were delivered by the related Mortgage Loan Seller but are out for filing or recording and have not been returned by the filing office or the recorder’s office).

(c)       The Custodian shall review the Mortgage Loan documents received subsequent to the Closing Date; and, on or about the first anniversary of the Closing Date, the Custodian shall, in the form attached as Exhibit Q, certify in writing to each of the Depositor, the Master Servicer, the Special Servicer, the Trustee, the Certificate Administrator, the Directing Holder (so long as no Consultation Termination Event shall have occurred and be continuing and only with respect to the Mortgage Loans, the Y&L Towers Trust Subordinate Companion Loan or the Standard Highline Trust Subordinate Companion Loan other than any Excluded Loan with respect to the Directing Holder or, if the Directing Holder is the Directing Certificateholder, the Holder of the majority of the Controlling Class), the Operating Advisor, the Asset Representations Reviewer and the applicable Mortgage Loan Seller (as to each Mortgage Loan (or the Y&L Towers Trust Subordinate Companion Loan or the Standard Highline Trust Subordinate Companion Loan) listed on the Mortgage Loan Schedule (other than any related Mortgage Loan as to which a Liquidation Event has occurred) or any related Mortgage Loan or Trust Subordinate Companion Loan specifically identified in any exception report annexed to such writing) that, (i) subject to the final proviso of the definition of “Mortgage File” herein and Section 2.01 hereof, all documents specified in clauses (i) through (v), (viii), (ix), (xi), (xii) and (xiii), if any, of the definition of “Mortgage File”, as applicable, are in its possession, (ii) the foregoing documents delivered or caused to be delivered by the Mortgage Loan Sellers have been reviewed by the Custodian and appear regular on their face and appear to be executed and relate to such Mortgage Loan or Trust Subordinate Companion Loan and (iii) based on such examination and only as to the foregoing documents, the information set forth in the Mortgage Loan Schedule with respect to the items specified in clauses (iv), (vi) and (viii)(c) in the definition of “Mortgage Loan Schedule” is correct.

 -184-

(d)       Notwithstanding anything contained in this Section 2.02 and Section 2.03(b) to the contrary, in the case of a Material Defect in any of the documents specified in clauses (ii) through (v), (vii), (viii) and (ix) in the definition of “Mortgage File”, which Material Defect results solely from a delay in the return of the related documents from the applicable filing or recording office and gives rise to a repurchase or substitution obligation on the part of the related Mortgage Loan Seller with respect to the subject Mortgage Loan or Trust Subordinate Companion Loan pursuant to the related Mortgage Loan Purchase Agreement, the Directing Holder, in its sole judgment, may (other than with respect to any Excluded Loan with respect to the Directing Holder or, if the Directing Holder is the Directing Certificateholder, or the Holder of the majority of the Controlling Class and, with respect to any other Mortgage Loan, only prior to the occurrence and continuance of a Control Termination Event), and the Special Servicer may, in accordance with the Servicing Standard, after the occurrence and during the continuance of a Control Termination Event, permit the related Mortgage Loan Seller in lieu of repurchasing or substituting for the related Mortgage Loan or Trust Subordinate Companion Loan, to deposit with the Master Servicer an amount, to be held in trust in a segregated Eligible Account (which may be a sub-account of the Collection Account), equal to 25% of the Stated Principal Balance of the related Mortgage Loan or Trust Subordinate Companion Loan (in the alternative, the related Mortgage Loan Seller may deliver to the Master Servicer a letter of credit in such amount, with a copy to the Custodian). Such funds or letter of credit, as applicable, shall be held by the Master Servicer (i) until the date on which the Custodian determines and notifies the Master Servicer that such Material Defect has been cured or the related Mortgage Loan or Trust Subordinate Companion Loan is no longer part of the Trust Fund, at which time the Master Servicer shall return such funds (or letter of credit) to the related Mortgage Loan Seller, or (ii) until same are applied to the Purchase Price (or the Substitution Shortfall Amount, if applicable) as set forth below in this Section 2.02(d) in the event of a repurchase or substitution by the related Mortgage Loan Seller. Notwithstanding the two immediately preceding sentences, if the Master Servicer or the Special Servicer certifies to the Trustee, the Certificate Administrator and the Custodian that it has determined in the exercise of its reasonable judgment that the document with respect to which such Material Defect exists is required in connection with an imminent enforcement of the mortgagee’s rights or remedies under the related Mortgage Loan or Trust Subordinate Companion Loan, defending any claim asserted by any Mortgagor or third party with respect to the related Mortgage Loan or Trust Subordinate Companion Loan, establishing the validity or priority of any lien on collateral securing the related Mortgage Loan or Trust Subordinate Companion Loan or for any immediate significant servicing obligation, the related Mortgage Loan Seller shall be required to repurchase or substitute for the related Mortgage Loan or Trust Subordinate Companion Loan in accordance with, and to the extent required by, the terms and conditions of Section 2.03(b) and Section 6 of the related Mortgage Loan Purchase Agreement; provided, however, that such Mortgage Loan Seller shall not be required to repurchase the Mortgage Loan or Trust Subordinate Companion Loan for a period of ninety (90) days after receipt of a notice to repurchase (together with any applicable extension period) if it is attempting to recover the document from the applicable filing or recording office and provides an officer’s certificate setting forth what actions such Mortgage Loan Seller is pursuing in connection with such recovery. In the event of a repurchase or substitution, upon the date of such repurchase or substitution, and in the event that the related Mortgage Loan Seller has delivered a letter of credit to the Master Servicer in accordance with this Section 2.02(d), the Master Servicer shall, to the extent necessary, draw on the letter of credit and deposit the

 -185-

proceeds of such draw, into the Collection Account to be applied to the Purchase Price (or the Substitution Shortfall Amount, if applicable, in which event, the amount of such funds or proceeds that exceed the Substitution Shortfall Amount shall be returned to the related Mortgage Loan Seller) in accordance with Section 2.03(b). All such funds deposited in the Collection Account shall be invested in Permitted Investments, at the direction and for the benefit of the related Mortgage Loan Seller. Such funds shall be treated as an “outside reserve fund” under the REMIC Provisions, which, together with any reimbursement from the Lower-Tier REMIC, is beneficially owned by the related Mortgage Loan Seller for federal income tax purposes, which Mortgage Loan Seller shall remain liable for any taxes payable on income or gain with respect thereto.

(e)       It is herein acknowledged that neither the Trustee nor any Custodian is under any duty or obligation (i) to determine whether any of the documents specified in clauses (vi), (vii) and (xii) through (xvii) of the definition of “Mortgage File” exist or are required to be delivered by the Depositor, the Mortgage Loan Sellers or any other Person (unless identified on the Mortgage Loan Checklist) or (ii) to inspect, review or examine any of the documents, instruments, certificates or other papers relating to the Mortgage Loans or the Trust Subordinate Companion Loans delivered to it to determine that the same are genuine, enforceable, duly authorized, sufficient to perfect and maintain the perfection of a security interest or appropriate for the represented purpose or that they are other than what they purport to be on their face and, with respect to the documents specified in clause (viii) of the definition of the “Mortgage File”, whether the insurance is effective as of the date of the recordation, whether all endorsements or riders issued are included in the file or if the policy has not been issued whether any acceptable replacement document has been dated the date of the related Mortgage Loan funding. Further, with respect to the UCC Financing Statements referenced in the Mortgage File, absent actual knowledge to the contrary or copies of UCC Financing Statements delivered to the Custodian as part of the Mortgage File indicating otherwise, the Custodian may assume, for the purposes of the filings and the certification to be delivered in accordance with this Section 2.02 that the related Mortgage File should include one state level UCC Financing Statement filing for each Mortgaged Property (or with respect to any Mortgage Loan that has two or more Mortgagors, for each Mortgagor, except to the extent multiple Mortgagors are named as debtors in the same UCC Financing Statement filing), or if the Custodian has received notice that a particular UCC Financing Statement was filed as a fixture filing, that the related Mortgage File should include only a local UCC Financing Statement filing for each Mortgaged Property (or with respect to any Mortgage Loan that has two or more Mortgagors, for each Mortgagor, except to the extent multiple Mortgagors are named as debtors in the same UCC Financing Statement filing). The assignments of the UCC Financing Statements to be assigned to the Trust will be delivered on the new national forms (or on such other form as may be acceptable for filing or recording in the applicable jurisdiction) and in a format suitable for filing or recording, as applicable, and will be filed or recorded in the jurisdiction(s) where such UCC Financing Statements were originally filed or recorded, as indicated in the documents provided, and in accordance with then-current laws.

(f)       If, in the process of reviewing the Mortgage Files or at any time thereafter, the Custodian finds any document or documents constituting a part of a Mortgage File (1) not to have been properly executed, (2) subject to the timing requirements of Sections 2.01(b) and 2.01(c), not to have been delivered, (3) to contain information that does not conform in any

 -186-

material respect with the corresponding information set forth in the Mortgage Loan Schedule or (4) to be defective on its face (each, a “Defect” in the related Mortgage File), the Custodian shall promptly so notify the Depositor, the Trustee, the Master Servicer, the Special Servicer, the Certificate Administrator, the Directing Holder, the applicable Mortgage Loan Seller (and in no event later than ninety (90) days after the Closing Date and every calendar quarter thereafter until all Defects are corrected) by providing a Custodial Exception Report setting forth for each affected Mortgage Loan or Trust Subordinate Companion Loan, with particularity, the nature of such Defect (in a form reasonably acceptable to the Custodian and such Mortgage Loan Seller and separating items required to be in the Mortgage File but never delivered from items which were delivered by such Mortgage Loan Seller but are out for recording or filing and have not been returned by the recorder’s office or filing office).

(g)       If the Master Servicer or the Special Servicer (i) receives any request or demand for repurchase or replacement of a Mortgage Loan or Trust Subordinate Companion Loan because of a breach of or alleged breach of a representation or warranty or a Defect (any such request or demand for repurchase or replacement, a “Repurchase Request”, and the Master Servicer or the Special Servicer, as applicable, to the extent it receives a Repurchase Request, the “Repurchase Request Recipient” with respect to such Repurchase Request); or (ii) receives any withdrawal of a Repurchase Request by the Person making such Repurchase Request or any rejection of a Repurchase Request (or such a Repurchase Request is forwarded to the Master Servicer or the Special Servicer by another party hereto), then the Repurchase Request Recipient shall deliver notice (which may be by electronic format so long as a “backup” hard copy of such notice is also delivered on or prior to the next Business Day) of such Repurchase Request or withdrawal or rejection of a Repurchase Request (each, a “15Ga-1 Notice”) to the applicable Mortgage Loan Seller (other than in the case of a rejection by such Mortgage Loan Seller) and the Depositor, in each case within ten (10) Business Days from such Repurchase Request Recipient’s receipt thereof.

Each 15Ga-1 Notice shall include (i) the identity of the related Mortgage Loan or Trust Subordinate Companion Loan, (ii) the date the Repurchase Request is received by the Repurchase Request Recipient or the date any withdrawal of the Repurchase Request is received by the Repurchase Request Recipient, as applicable, (iii) if known, the basis for the Repurchase Request (as asserted in the Repurchase Request) and (iv) a statement from the Repurchase Request Recipient as to whether it currently plans to pursue such Repurchase Request.

A Repurchase Request Recipient shall not be required to provide any information in a 15Ga-1 Notice protected by the attorney-client privilege or attorney work product doctrines. The Mortgage Loan Purchase Agreements will provide that (i) any 15Ga-1 Notice provided pursuant to this Section 2.02(g) is so provided only to assist the Mortgage Loan Sellers and Depositor or their respective Affiliates to comply with Rule 15Ga-1 under the Exchange Act, Items 1104 and 1121 of Regulation AB and any other requirement of law or regulation and (ii) (A) no action taken by, or inaction of, a Repurchase Request Recipient and (B) no information provided pursuant to this Section 2.02(g) by a Repurchase Request Recipient, shall be deemed to constitute a waiver or defense to the exercise of any legal right the Repurchase Request Recipient may have with respect to the related Mortgage Loan Purchase Agreement, including with respect to any Repurchase Request that is the subject of a 15Ga-1 Notice.

 -187-

In the event that the Depositor, the Trustee, the Certificate Administrator, the Operating Advisor, the Asset Representations Reviewer or the Custodian receives a Repurchase Request, such party shall promptly forward or otherwise provide written notice of such Repurchase Request to the Master Servicer, if relating to a Non-Specially Serviced Loan, or to the Special Servicer, if relating to a Specially Serviced Loan or REO Property, and include the following statement in the related correspondence: “This is a ‘Repurchase Request’ under Section 2.02 of the Pooling and Servicing Agreement relating to the CSAIL 2017-CX10 Commercial Mortgage Trust, Commercial Mortgage Pass-Through Certificates, Series 2017-CX10 requiring action by you as the ‘Repurchase Request Recipient’ thereunder.” Upon receipt of such Repurchase Request by the Master Servicer or the Special Servicer, as applicable, such party shall be deemed to be the Repurchase Request Recipient in respect of such Repurchase Request, and such party shall comply with the procedures set forth in this Section 2.02(g) with respect to such Repurchase Request. In no event shall the Custodian, by virtue of this provision, be required to provide any notice other than as set forth in Section 2.02 of this Agreement in connection with its review of the Mortgage File.

If the Depositor, the Trustee, the Certificate Administrator, the Operating Advisor, the Asset Representations Reviewer or the Custodian receives notice or has knowledge of a withdrawal or a rejection of a Repurchase Request of which notice has been previously received or given, and such notice was not received from or copied to the Master Servicer or the Special Servicer, then such party shall give notice of such withdrawal or rejection to the Master Servicer or the Special Servicer, as applicable. Any such notice received by the Trustee, the Certificate Administrator, the Operating Advisor, the Asset Representations Reviewer or the Custodian shall also be provided to the Depositor and, in the case of a withdrawal notice, to the applicable Mortgage Loan Seller.

In the event that a Mortgage Loan or Trust Subordinate Companion Loan is repurchased or replaced pursuant to Section 2.03 of this Agreement, the Master Servicer (with respect to Non-Specially Serviced Loans) or the Special Servicer (with respect to Specially Serviced Loans) shall promptly notify the Depositor of such repurchase or replacement.

(b)       If any Certificateholder, the Directing Holder, the Master Servicer, the Special Servicer, the Certificate Administrator, Operating Advisor (solely in its capacity as Operating Advisor) or the Trustee discovers (without implying any duty of such person to make, or to attempt to make, such a discovery) or receives notice alleging a Material Defect in any Mortgage File, such Certificateholder, the Directing Holder, the Master Servicer, the Special Servicer, the Trustee, Operating Advisor (solely in its capacity as Operating Advisor) or the Certificate Administrator, as applicable, shall give prompt written notice of such Material Defect to the Depositor, the Master Servicer, the Special Servicer, the applicable Mortgage Loan Seller, the Trustee, the Certificate Administrator, the Operating Advisor (solely in its capacity as Operating Advisor) and, prior to the occurrence of a Consultation Termination Event, the Directing Holder, and the Master Servicer (if the related Mortgage Loan is a Non-Specially Serviced Loan) or the Special Servicer (if the related Mortgage Loan is a Specially Serviced Loan), as applicable, shall request in writing that the applicable Mortgage Loan Seller, not later than ninety (90) days after (i) except in the case of the succeeding clause (ii), the applicable Mortgage Loan Seller’s discovery of the Material Defect or receipt of such notice or (ii) in the case of a Material Defect relating to a Mortgage Loan (with respect to the Yorkshire & Lexington Towers Mortgage Loan and The Standard Highline NYC Mortgage Loan, including

 -189-

the related Trust Subordinate Companion Loan) not being a Qualified Mortgage, the earlier of (x) the discovery by the Mortgage Loan Seller or any party to this Agreement of such Material Defect or (y) receipt of notice of a discovery of such Material Defect from any party to this Agreement by the Mortgage Loan Seller, (such ninety (90) day period, the “Initial Cure Period”), (A) cure such Material Defect in all material respects, at such Mortgage Loan Seller’s own expense, including reimbursement of any related reasonable additional expenses of the Trust reasonably incurred by any party to this Agreement, (B) repurchase the affected Mortgage Loan, Trust Subordinate Companion Loan or REO Mortgage Loan (excluding any related Companion Loan, if applicable) at the applicable Purchase Price and in conformity with the applicable Mortgage Loan Purchase Agreement and this Agreement or (C) substitute a Qualified Substitute Mortgage Loan (other than with respect to any Mortgage Loan that is part of a Whole Loan, for which no substitution will be permitted) for such affected Mortgage Loan or REO Mortgage Loan, and pay any Substitution Shortfall Amount in connection with such substitution (provided that in no event shall any such substitution occur on or after the second anniversary of the Closing Date) and pay the Master Servicer for deposit into the Collection Account, any Substitution Shortfall Amount in connection therewith and in conformity with the applicable Mortgage Loan Purchase Agreement and this Agreement; provided, however, that except with respect to a Material Defect resulting solely from the failure by the Mortgage Loan Seller to deliver to the Trustee or Custodian the actual policy of lender’s title insurance required pursuant to clause (viii) of the definition of Mortgage File by a date not later than eighteen (18) months following the Closing Date, if such Material Defect is capable of being cured but is not cured within the Initial Cure Period, and the applicable Mortgage Loan Seller has commenced and is diligently proceeding with the cure of such Material Defect within the Initial Cure Period, the applicable Mortgage Loan Seller shall have an additional ninety (90) days commencing immediately upon the expiration of the Initial Cure Period (such additional ninety (90) day period, the “Extended Cure Period”) to complete such cure (or, failing such cure, to repurchase the related Mortgage Loan or REO Loan (excluding any related Serviced Companion Loan, if applicable, except for the Trust Subordinate Companion Loans) or substitute a Qualified Substitute Mortgage Loan (other than with respect to any Mortgage Loan that is part of a Whole Loan, for which no substitution will be permitted) and pay any Substitution Shortfall Amount in connection with such substitution) and provided, further, that with respect to such Extended Cure Period the applicable Mortgage Loan Seller shall have delivered an officer’s certificate to the Trustee, the Certificate Administrator (who shall promptly deliver a copy of such officer’s certificate to the 17g-5 Information Provider), the Master Servicer, the Special Servicer, the Operating Advisor and (with respect to any Mortgage Loan other than an Excluded Loan with respect to the Directing Holder or, if the Directing Holder is the Directing Certificateholder, the Holder of the majority of the Controlling Class, prior to the occurrence and continuance of a Consultation Termination Event), the Directing Holder, setting forth the reason such Material Defect is not capable of being cured within the Initial Cure Period and what actions the applicable Mortgage Loan Seller is pursuing in connection with the cure thereof and stating that the applicable Mortgage Loan Seller anticipates that such Material Defect will be cured within the Extended Cure Period; and provided, further, that, if any such Material Defect is still not cured after the Initial Cure Period and any such Extended Cure Period solely due to the failure of the Mortgage Loan Seller to have received the recorded document, then the Mortgage Loan Seller shall be entitled to continue to defer its cure, substitution or repurchase obligations in respect of such Material Defect so long as the Mortgage Loan Seller certifies to the Trustee, the

 -190-

Special Servicer, the Master Servicer and the Certificate Administrator every 30 days thereafter that the Material Defect is still in effect solely because of its failure to have received the recorded document and that the Mortgage Loan Seller is diligently pursuing the cure of such defect (specifying the actions being taken), except that no such deferral of cure, substitution or repurchase may continue beyond the date that is 18 months following the Closing Date. Any such repurchase or substitution of a Mortgage Loan shall be on a whole loan, servicing released basis. Notwithstanding the foregoing, any Material Defect which causes any Mortgage Loan or Trust Subordinate Companion Loan not to be a Qualified Mortgage shall be deemed to materially and adversely affect the interests of Certificateholders therein, and (subject to the applicable Mortgage Loan Seller’s right to cure such Material Defect during the Initial Cure Period) such Mortgage Loan or Trust Subordinate Companion Loan shall be repurchased or substituted for without regard to the Extended Cure Period described in the preceding sentence. If the affected Mortgage Loan or Trust Subordinate Companion Loan is to be repurchased, the funds in the amount of the Purchase Price remitted by the applicable Mortgage Loan Seller are to be remitted by wire transfer to the Master Servicer for deposit into the Collection Account.

If a Mortgage Loan Seller, in connection with a Material Defect (or an allegation of a Material Defect) pertaining to a Mortgage Loan or Trust Subordinate Companion Loan, makes a cash payment pursuant to an agreement or a settlement between the applicable Mortgage Loan Seller and the Master Servicer or the Special Servicer, as applicable, on behalf of the Trust (and, for so long as no Control Termination Event has occurred and is continuing and in respect of any Mortgage Loan that is not a Servicing Shift Mortgage Loan or an Excluded Loan with respect to the Directing Holder or, if the Directing Holder is the Directing Certificateholder, the Holder of the majority of the Controlling Class, the consent of the Directing Holder) (each such payment, a “Loss of Value Payment”) with respect to such Mortgage Loan or Trust Subordinate Companion Loan, the amount of such Loss of Value Payment shall be deposited into the Loss of Value Reserve Fund to be applied in accordance with Section 3.05(g) of this Agreement. The Loss of Value Payment shall include the portion of any Liquidation Fees payable to the Special Servicer in respect of such Loss of Value Payment and the portion of fees and reimbursable expenses of the Asset Representations Reviewer attributable to the Asset Review of such Mortgage Loan. If such Loss of Value Payment is made, the Loss of Value Payment shall serve as the sole remedy available to the Certificateholders and the Trustee on their behalf regarding any such Material Defect in lieu of any obligation of the Mortgage Loan Seller to otherwise cure such Material Defect or repurchase or substitute for the affected Mortgage Loan or Trust Subordinate Companion Loan based on such Material Defect under any circumstances. This paragraph is intended to apply only to a mutual agreement or settlement between the applicable Mortgage Loan Seller and the Master Servicer (in the case of Non-Specially Serviced Loans) or the Special Servicer (in the case of Specially Serviced Loans) on behalf of the Trust, provided that (i) prior to any such agreement or settlement nothing in this paragraph shall preclude the Mortgage Loan Seller or the Master Servicer or the Special Servicer, as applicable, from exercising any of its rights related to a Material Defect in the manner and timing set forth in the related Mortgage Loan Purchase Agreement or this Section 2.03 (excluding this paragraph) (including any right to cure, repurchase or substitute for such Mortgage Loan or Trust Subordinate Companion Loan), (ii) such Loss of Value Payment shall not be greater than the Purchase Price of the affected Mortgage Loan or Trust Subordinate Companion Loan; and (iii) a Material Defect as a result of a Mortgage Loan or Trust Subordinate Companion Loan not constituting a Qualified Mortgage may not be cured by a Loss of Value Payment.

 -191-

With respect to any Non-Serviced Mortgage Loan, if any “Material Defect” (or analogous term) exists under the related Non-Serviced PSA, and if the applicable Mortgage Loan Seller (or other responsibly party) repurchases the Non-Serviced Companion Loan securitized thereunder from the trust created pursuant to such Non-Serviced PSA, then the related Mortgage Loan Seller shall promptly repurchase such Non-Serviced Mortgage Loan at the applicable Purchase Price; provided, however, that the foregoing shall not apply to any Defect related solely to the promissory note for any related Non-Serviced Companion Loan.

If any Breach pertains to a representation or warranty that the related Mortgage Loan documents or any particular Mortgage Loan document requires the related Mortgagor to bear the costs and expenses associated with any particular action or matter under such Mortgage Loan document(s), then the related Mortgage Loan Seller may cure such Breach within the applicable cure period (as the same may be extended) by reimbursing the Trust (by wire transfer of immediately available funds) for (i) the reasonable amount of any such costs and expenses incurred by the Master Servicer, the Special Servicer, the Certificate Administrator, the Trustee or the Trust that are incurred as a result of such Breach and have not been reimbursed by the related Mortgagor and (ii) if such Mortgage Loan is or was a Delinquent Loan subject to an Asset Review, the amount of any fees payable, without duplication, pursuant to Section 12.02(b) to the extent not previously paid by the Mortgage Loan Seller to the Asset Representations Reviewer attributable to the Asset Review of such Mortgage Loan; provided, however, that in the event any such costs and expenses exceed $10,000, the related Mortgage Loan Seller shall have the option to either repurchase or substitute for the related Mortgage Loan as provided above or pay such costs and expenses. Except as provided in the proviso to the immediately preceding sentence, the related Mortgage Loan Seller shall remit the amount of such costs and expenses and upon its making such remittance, the related Mortgage Loan Seller shall be deemed to have cured such Breach in all respects. To the extent any fees or expenses that are the subject of a cure by the related Mortgage Loan Seller are subsequently obtained from the related Mortgagor, the portion of the cure payment made by the related Mortgage Loan Seller equal to such fees or expenses obtained from the related Mortgagor shall promptly be returned to the related Mortgage Loan Seller. Periodic Payments due with respect to each Qualified Substitute Mortgage Loan (if any) after the related Due Date in the month of substitution, and Periodic Payments due with respect to each Mortgage Loan being repurchased or replaced after the related Cut-off Date and received by the Master Servicer or the Special Servicer on behalf of the Trust on or prior to the related date of repurchase or substitution, shall be part of the Trust Fund. Periodic Payments due with respect to each Qualified Substitute Mortgage Loan (if any) on or prior to the related Due Date in the month of substitution, and Periodic Payments due with respect to each Mortgage Loan being repurchased or replaced and received by the Master Servicer or the Special Servicer on behalf of the Trust after the related date of repurchase or substitution, shall not be part of the Trust Fund and are to be remitted by the Master Servicer or the Special Servicer to the applicable Mortgage Loan Seller effecting the related repurchase or substitution promptly following receipt. Notwithstanding anything contained in this Agreement or the related Mortgage Loan Purchase Agreement, no delay in either the discovery of a Material Defect or in providing notice of such Material Defect shall relieve the applicable Mortgage Loan Seller of its obligation to cure, repurchase or substitute for (or make a Loss of Value Payment with respect to) the related Mortgage Loan or Trust Subordinate Companion Loan if it is otherwise required to do so under the related Mortgage Loan Purchase Agreement and/or this Article II unless (i) the related Mortgage Loan Seller did not otherwise discover or have

 -192-

knowledge of such Material Defect, (ii) such delay is a result of the failure by a party to the applicable Mortgage Loan Purchase Agreement, or this Agreement (other than the Asset Representations Reviewer), to provide prompt notice as required by the terms of the applicable Mortgage Loan Purchase Agreement, or this Agreement, after such party has actual knowledge of such Material Defect (knowledge shall not be deemed to exist by reason of the Custodial Exception Report), (iii) such Material Defect does not relate to the applicable Mortgage Loan (which, with respect to the Yorkshire & Lexington Towers Mortgage Loan and The Standard Highline NYC Mortgage Loan, shall also include the related Trust Subordinate Companion Loan) not being a Qualified Mortgage and (iv) such delay precludes such Mortgage Loan Seller from curing such Material Defect.

Pursuant to each Mortgage Loan Purchase Agreement, if there is a Material Defect with respect to one or more Mortgaged Properties with respect to a Mortgage Loan, the related Mortgage Loan Seller shall not be obligated to repurchase the Mortgage Loan if (i) the affected Mortgaged Property may be released pursuant to the terms of any partial release provisions in the related Mortgage Loan documents (and such Mortgaged Property is, in fact, released), (ii) the remaining Mortgaged Property(ies) satisfy the requirements, if any, set forth in the Mortgage Loan documents and the related Mortgage Loan Seller provides an opinion of counsel to the effect that such release in lieu of a repurchase would not (A) cause any Trust REMIC to fail to qualify as a REMIC or (B) result in the imposition of a tax upon any Trust REMIC or the issuing entity and (iii) each applicable Rating Agency has provided a Rating Agency Confirmation.

(c)       Subject to the applicable Mortgage Loan Seller’s right to cure as contemplated above in this Section 2.03, and further subject to Section 2.01(b) and Section 2.01(c), any of the following shall cause a document in the Mortgage File to be deemed to have a “Defect” that constitutes a Material Defect and to be conclusively presumed to materially and adversely affect the interests of Certificateholders in a Mortgage Loan or a Trust Subordinate Companion Loan, as applicable, (but solely with respect to clause (a)) and to be deemed to materially and adversely affect the interest of the Certificateholders in and the value of a Mortgage Loan or Trust Subordinate Companion Loan, as applicable: (a) the absence from the Mortgage File of the original signed Mortgage Note, unless the Mortgage File contains a signed lost note affidavit and indemnity with a copy of the Mortgage Note that appears to be regular on its face; (b) the absence from the Mortgage File of the original signed Mortgage that appears to be regular on its face, unless there is included in the Mortgage File either a copy of the Mortgage with evidence of recording thereon or a copy of the Mortgage and a certificate from the related Mortgage Loan Seller stating that the original signed Mortgage was sent for recordation (or certified by the applicable recorder’s office); (c) the absence from the Mortgage File of the item called for by clause (viii) of the definition of Mortgage File; (d) the absence from the Mortgage File of any intervening assignments required to create a complete chain of assignments to the Trustee on behalf of the Trust, unless there is included in the Mortgage File either a copy of the assignment with evidence of recording thereon or a copy of the intervening assignment and a certificate from the related Mortgage Loan Seller stating that the original intervening assignments were sent for filing or recordation (or certified by the applicable recorder’s office), as applicable; (e) the absence from the Mortgage File of any required letter of credit (except as permitted under Section 2.01(b)); or (f) with respect to any related leasehold Mortgage Loan, the absence from the related Mortgage File of a copy (or an original, if

 -193-

available) of the related Ground Lease; provided, however, that no Defect (except the Defects previously described in subclauses (a) through (f) of this Section 2.03(c)) shall be considered to materially and adversely affect the value of the related Mortgage Loan, the value of the related Mortgaged Property or the interests of the Trustee or Certificateholders unless the document with respect to which the Defect exists is required in connection with an imminent enforcement of the mortgagee’s rights or remedies under the related Mortgage Loan, defending any claim asserted by any Mortgagor or third party with respect to the related Mortgage Loan or Trust Subordinate Companion Loan, establishing the validity or priority of any lien on any collateral securing the related Mortgage Loan or Trust Subordinate Companion Loan or for any immediate significant servicing obligation; provided, further, that no Defect relating to any Non-Serviced Mortgage Loan previously described in subclauses (b) through (f) of this Section 2.03(c) shall be considered to materially and adversely affect the value of such Mortgage Loan, the value of the related Mortgaged Property or the interests of the Trustee or Certificateholders unless the related Mortgage Loan Seller, after receipt of notice of such Defect, is unable to produce a copy of the document with respect to which the Defect exists within a reasonable period after receiving such notice or otherwise establish that the original or copy, as applicable, of such document has been delivered, in compliance with the terms of the related Non-Serviced PSA, to the custodian under the related Non-Serviced PSA. Notwithstanding the foregoing, the delivery of executed escrow instructions or a binding commitment to issue a lender’s title insurance policy, as provided in clause (viii) of the definition of Mortgage File herein, in lieu of the delivery of the actual policy of lender’s title insurance, shall not be considered a Material Defect with respect to any Mortgage File if such actual policy is delivered to the Custodian not later than eighteen (18) months following the Closing Date. Notwithstanding the foregoing, to the extent a Mortgage Loan Seller has otherwise complied with its document delivery requirements under this Agreement and the related Mortgage Loan Purchase Agreement, in the event that the Custodian has acknowledged receipt pursuant to Section 2.02 above of a document that is part of the Mortgage File or a Mortgage Loan Seller can otherwise prove delivery of the document, and the Custodian subsequently loses a document, the fact that such document is lost may not be utilized as the basis for a claim of a Material Defect against a Mortgage Loan Seller pursuant to Section 6(e) of the related Mortgage Loan Purchase Agreement and/or this Section 2.03 and the Custodian shall be liable for any such loss to the extent provided for in Section 8.01.

(d)       In connection with any repurchase of, or substitution of a Qualified Substitute Mortgage Loan for, a Mortgage Loan or any repurchase of a Trust Subordinate Companion Loan contemplated by this Section 2.03, the Trustee, the Certificate Administrator, the Custodian, the Master Servicer and the Special Servicer shall each tender to the applicable Mortgage Loan Seller, upon delivery to each of the Trustee, the Certificate Administrator, the Custodian, the Master Servicer and the Special Servicer of a trust receipt executed by the applicable Mortgage Loan Seller evidencing such repurchase or substitution (other than with respect to any Trust Subordinate Companion Loan in the case of a substitution), all portions of the Mortgage File and other documents pertaining to such Mortgage Loan, Trust Subordinate Companion Loan possessed by each of the Trustee, the Certificate Administrator, the Custodian, the Master Servicer and the Special Servicer (other than attorney-client communications that are privileged communications), and each document that constitutes a part of the Mortgage File that was endorsed or assigned to the Trustee shall be endorsed or assigned, as the case may be, to the applicable Mortgage Loan Seller in the same manner as provided in Section 6 of the related Mortgage Loan Purchase Agreement and, if applicable, the definition of “Mortgage File” herein,

 -194-

so as to vest in such Mortgage Loan Seller the legal and beneficial ownership of such repurchased or substituted Mortgage Loan or Trust Subordinate Companion Loan (including property acquired in respect thereof and proceeds of any insurance policy with respect thereto) and the related Mortgage Loan documents.

(e)       Section 6 of each of the Mortgage Loan Purchase Agreements provides the sole remedy available to the Certificateholders (subject to the limitations on the rights of the Certificateholders under this Agreement), or the Trustee on behalf of the Certificateholders, the Master Servicer or the Special Servicer, with respect to any Defect in a Mortgage File or any Breach of any representation or warranty with respect to a Mortgage Loan or Trust Subordinate Companion Loan set forth in or required to be made pursuant to Section 6 of any of the Mortgage Loan Purchase Agreements; provided that the foregoing shall in no way limit the ability of the Master Servicer, Special Servicer or Trustee to take any action against BSPCC or BSPRTI, as applicable, to the extent provided for pursuant to the related Mortgage Loan Purchase Agreement, including, without limitation, pursuant to Sections 20 and 21 thereof..

(f)        The Master Servicer (in the case of Non-Specially Serviced Loans) or the Special Servicer (in the case of Specially Serviced Loans) shall, for the benefit of the Certificateholders and the Trustee (as holder of the Lower-Tier Regular Interests), enforce the obligations of the applicable Mortgage Loan Seller under the applicable Mortgage Loan Purchase Agreement. Such enforcement, including, without limitation, the legal prosecution of claims, if any, shall be carried out in accordance with the Servicing Standard. Any costs incurred by the Master Servicer or the Special Servicer with respect to the enforcement of the obligations of the applicable Mortgage Loan Seller under the applicable Mortgage Loan Purchase Agreement shall, to the extent not recovered from the applicable Mortgage Loan Seller, be deemed to be Servicing Advances to the extent not otherwise provided for herein. The Master Servicer or the Special Servicer, as applicable, shall be reimbursed for the reasonable costs of such enforcement: first, from a specific recovery, if any, of costs, expenses or attorneys’ fees against the applicable Mortgage Loan Seller; second, pursuant to Section 3.05(a)(vii) herein out of the related Purchase Price, to the extent that such expenses are a specific component thereof; and third, if at the conclusion of such enforcement action it is determined that the amounts described in clauses first and second are insufficient, then pursuant to Section 3.05(a)(viii) herein out of general collections on the Mortgage Loans on deposit in the Collection Account. Any costs, expenses or attorneys’ fees related to a repurchase of a Companion Loan shall be paid pursuant to the related Intercreditor Agreement or pursuant to the documents related to an Other Securitization, if applicable.

(g)       If a Mortgage Loan Seller incurs any expense in connection with the curing of a Breach, which also constitutes a default under the related Mortgage Loan or Trust Subordinate Companion Loan, as applicable, and is reimbursable thereunder, such Mortgage Loan Seller shall have a right, and shall be subrogated to the rights of the Trustee and the Trust under the Mortgage Loan to recover the amount of such expenses from the related Mortgagor; provided, however, that such Mortgage Loan Seller’s rights pursuant to this Section 2.03(g) shall be junior, subject and subordinate to the rights of the Trustee, the Certificate Administrator, the Trust, the Master Servicer and the Special Servicer to recover amounts owed by the related Mortgagor under the terms of such Mortgage Loan including, without limitation, the rights to recover unreimbursed Advances, accrued and unpaid interest on Advances at the Reimbursement

 -195-

Rate, fees owed to the Special Servicer, and unpaid or unreimbursed expenses of the Trustee, the Certificate Administrator, the Trust, the Master Servicer or the Special Servicer allocable to such Mortgage Loan. The Master Servicer or, with respect to a Specially Serviced Loan, the Special Servicer, shall use reasonable efforts to recover such expenses for such Mortgage Loan Seller to the extent consistent with the Servicing Standard, but taking into account the subordinate nature of the reimbursement to the related Mortgage Loan Seller; provided, however, that the Master Servicer or, with respect to a Specially Serviced Loan, the Special Servicer, determines in the exercise of its sole discretion consistent with the Servicing Standard that such actions by it will not impair the Master Servicer’s and/or the Special Servicer’s collection or recovery of principal, interest and other sums due with respect to the related Mortgage Loan that would otherwise be payable to the Master Servicer, the Special Servicer, the Trustee, the Certificate Administrator and the Certificateholders pursuant to the terms of this Agreement; provided, further, that the Master Servicer or, with respect to a Specially Serviced Loan, the Special Servicer, may waive the collection of amounts due on behalf of such Mortgage Loan Seller in its sole discretion in accordance with the Servicing Standard.

(h)       If (i) any Crossed Underlying Loan is required to be repurchased or substituted for in the manner described in this Section 2.03 and (ii) the applicable Material Defect does not constitute a Material Defect as to any other Crossed Underlying Loan in the related Crossed Mortgage Loan Group (without regard to this paragraph), then the applicable Material Defect shall be deemed to constitute a Material Defect as to any other Crossed Underlying Loan in the related Crossed Mortgage Loan Group for purposes of this paragraph, and the related Mortgage Loan Seller shall repurchase or substitute for such other Crossed Underlying Loan(s) in the related Crossed Mortgage Loan Group as provided in Section 2.03(b) unless such other Crossed Underlying Loans satisfy the Crossed Underlying Loan Repurchase Criteria. In the event that the remaining Crossed Underlying Loans in such Crossed Mortgage Loan Group satisfy the Crossed Underlying Loan Repurchase Criteria, the applicable Mortgage Loan Seller may elect either to repurchase or substitute for only the affected Crossed Underlying Loan(s) as to which the related Material Defect exists or to repurchase or substitute for all of the Crossed Underlying Loans in the related Crossed Mortgage Loan Group. Any reserve or other cash collateral or letters of credit securing the Crossed Underlying Loans shall be allocated among the related Crossed Underlying Loans in accordance with the related Mortgage Loan documents or otherwise on a pro rata basis based upon their outstanding Stated Principal Balances. Except as provided in this Section 2.03(h) and Section 2.03(i), all other terms of the related Mortgage Loans shall remain in full force and effect without any modification thereof.

(i)        Notwithstanding the foregoing, if the related Mortgage provides for the partial release of one or more of the Crossed Underlying Loans, the Depositor may cause the related Mortgage Loan Seller to repurchase only that Crossed Underlying Loan required to be repurchased pursuant to this Section 2.03, pursuant to the partial release provisions of the related Mortgage; provided, however, that (i) the remaining related Crossed Underlying Loan(s) fully comply with the terms and conditions of the related Mortgage, this Agreement and the related Mortgage Loan Purchase Agreement, including the Crossed Underlying Loan Repurchase Criteria, (ii) in connection with such partial release, the related Mortgage Loan Seller obtains an Opinion of Counsel (at such Mortgage Loan Seller’s expense) to the effect that the contemplated action will not cause an Adverse REMIC Event and (iii) in connection with such partial release,

 -196-

the related Mortgage Loan Seller delivers or causes to be delivered to the Custodian original modifications to the Mortgage prepared and executed in connection with such partial release.

(j)        With respect to any Crossed Underlying Loan, to the extent that the applicable Mortgage Loan Seller is required to repurchase or substitute for such Crossed Underlying Loan in the manner prescribed in Section 2.03(h) or Section 2.03(i) while the Trustee continues to hold any other Crossed Underlying Loans in the related Crossed Mortgage Loan Group, the applicable Mortgage Loan Seller and the applicable Master Servicer or, with respect to a Specially Serviced Loan, the Special Servicer, on behalf of the Trustee, as assignee of the Depositor, will, as set forth in the related Mortgage Loan Purchase Agreement, forbear from enforcing any remedies against the other’s Primary Collateral but each will be permitted to exercise remedies against the Primary Collateral securing its respective related Mortgage Loans, including with respect to the Trustee, the Primary Collateral securing the Mortgage Loans still held by the Trustee, so long as such exercise does not materially impair the ability of the other party to exercise its remedies against its Primary Collateral. If the exercise of the remedies by one party would materially impair the ability of the other party to exercise its remedies with respect to the Primary Collateral securing the Crossed Underlying Loans held by such party, then both parties have agreed in the related Mortgage Loan Purchase Agreement to forbear from exercising such remedies until the Mortgage Loan documents evidencing and securing the relevant Mortgage Loan can be modified in a manner that complies with the related Mortgage Loan Purchase Agreement to remove the threat of material impairment as a result of the exercise of remedies.

(k)       (i) In the event an Initial Requesting Certificateholder delivers a written request to a party to this Agreement that a Mortgage Loan or Trust Subordinate Companion Loan be repurchased by the applicable Mortgage Loan Seller alleging the existence of a Material Defect with respect to such Mortgage Loan or Trust Subordinate Companion Loan and setting forth the basis for such allegation (a “Certificateholder Repurchase Request”), such party shall promptly forward that Certificateholder Repurchase Request to the related Mortgage Loan Seller and each other party to this Agreement. Subject to Section 2.03(l), the Master Servicer (in the case of Non-Specially Serviced Loans) and the Special Servicer (in the case of Specially Serviced Loans) (the “Enforcing Servicer”) shall be the Enforcing Party with respect to a Certificateholder Repurchase Request.

(ii)         In the event that the Depositor, the Master Servicer, the Special Servicer, the Trustee, the Certificate Administrator or the Operating Advisor (solely in its capacity as Operating Advisor) obtains knowledge of a Material Defect with respect to a Mortgage Loan or Trust Subordinate Companion Loan, that party shall deliver prompt written notice of such Material Defect to each other party to this Agreement identifying the applicable Mortgage Loan or Trust Subordinate Companion Loan and setting forth the basis for such allegation (an “PSA Party Repurchase Request” and, either a Certificateholder Repurchase Request or a PSA Party Repurchase Request, the “Repurchase Request”) and the Master Servicer (with respect to Non-Specially Serviced Loans) or the Special Servicer (with respect to Specially Serviced Loans) will be required to promptly send the PSA Party Repurchase Request to the related Mortgage Loan Seller. Prior to the occurrence of a Resolution Failure, the Master Servicer (with respect to Non-Specially Serviced Loans) or the Special Servicer (with respect to Specially Serviced Loans) shall act as the Enforcing

 -197-

Party and enforce the rights of the Trust against the related Mortgage Loan Seller with respect to a PSA Party Repurchase Request.

(iii)        In the event the Repurchase Request is not Resolved within 180 days after the Mortgage Loan Seller receives the Repurchase Request (a “Resolution Failure”), then the provisions described in Section 2.03(l) below shall apply. Receipt of the Repurchase Request shall be deemed to occur two (2) Business Days after the Repurchase Request is sent to the related Mortgage Loan Seller.

After the Dispute Resolution Cut-off Date, if no Certificateholder or Certificate Owner has become a Requesting Certificateholder, no Certificateholder or Certificate Owner shall have the right to elect to refer the Repurchase Request to mediation or arbitration and the Enforcing Servicer, as the Enforcing Party, shall be the sole party entitled to enforce the Trust’s rights against the related Mortgage Loan Seller, subject to the consent or consultation rights of the Directing Holder pursuant to Section 6.08.

(l)        (i) After a Resolution Failure occurs with respect to a Repurchase Request regarding a Mortgage Loan or Trust Subordinate Companion Loan (whether the Repurchase Request was initiated by an Initial Requesting Certificateholder or by a party to this Agreement), the Enforcing Servicer will be required to send a notice (a “Proposed Course of Action Notice”) to the Initial Requesting Certificateholder, if any, to the address specified in the Initial Requesting Certificateholder’s Repurchase Request, and to the Certificate Administrator (which shall be delivered via electronic mail to trustadministrationgroup@wellsfargo.com) who shall make such notice available to all other Certificateholders and Certificate Owners (by posting such notice on the Certificate Administrator’s Website) indicating the Enforcing Servicer’s intended course of action with respect to the Repurchase Request (a “Proposed Course of Action”). Such notice shall include (a) a request to Certificateholders to indicate their agreement with or dissent from such Proposed Course of Action by clearly marking “agree” or “disagree” to the Proposed Course of Action on such notice within 30 days of the date of such notice and a disclaimer that responses received after such 30-day period shall not be taken into consideration, (b) a statement that in the event any Certificateholder disagrees with the Proposed Course of Action, the Enforcing Servicer shall be compelled to follow or accept the course of action agreed to and/or proposed by the majority of the responding Certificateholders that involves referring the matter to mediation or arbitration, as the case may be, (c) a statement that responding Certificateholders will be required to certify their holdings in connection with such response, (d) a statement that only responses clearly marked “agree” or “disagree” with such Proposed Course of Action will be taken into consideration and (e) instructions for responding Certificateholders to send their responses to the applicable Enforcing Servicer and the Certificate Administrator. If (a) the Enforcing Servicer’s intended course of action with respect to the Repurchase Request does not involve pursuing further action to exercise rights against the applicable Mortgage Loan Seller with respect to the Repurchase Request but the Initial Requesting Certificateholder, if any, or any other Certificateholder or Certificate Owner wishes to exercise its right to refer the matter to mediation (including nonbinding arbitration) or arbitration, or (b) the Enforcing Servicer’s intended course of action is to pursue further action to exercise rights against the applicable Mortgage Loan Seller with respect to the Repurchase Request but the Initial Requesting Certificateholder, if any, or any other Certificateholder or Certificate Owner does not agree with the dispute resolution method selected by the Enforcing Servicer, then the Initial Requesting

 -198-

Certificateholder, if any, or such other Certificateholder or Certificate Owner may deliver to the Enforcing Servicer a written notice (a “Preliminary Dispute Resolution Election Notice”) within 30 days from the date the Proposed Course of Action Notice is posted on the Certificate Administrator’s Website (the “Dispute Resolution Cut-off Date”) indicating its intent to exercise its right to refer the matter to either mediation or arbitration. In the event any Certificateholder or Certificate Owner delivers a Preliminary Dispute Resolution Election Notice, and the Enforcing Servicer has also received responses from other Certificateholders or Certificate Owners supporting the Enforcing Servicer’s initial Proposed Course of Action, such responses shall be considered Preliminary Dispute Resolution Election Notices supporting the Proposed Course of Action. The Certificate Administrator shall within three (3) Business Days after the expiration of the 30-day response period, tabulate the responses received from the Certificateholders and share the results with the Enforcing Servicer. The Certificate Administrator shall only count responses timely received and clearly indicating agreement or dissent with the related Proposed Course of Action and additional verbiage or qualifying language shall not be taken into consideration for purposes of determining whether the related Certificateholder agrees or disagrees with the Proposed Course of Action. The Certificate Administrator shall be under no obligation to answer any questions from Certificateholders regarding such Proposed Course of Action. For the avoidance of doubt, the Certificate Administrator’s obligations in connection with this Section 2.03(l) shall be limited solely to tabulating Certificateholder responses of “agree” or “disagree” to the Proposed Course of Action, and such obligation shall not be construed to impose any enforcement obligation on the Certificate Administrator. The Enforcing Servicer may conclusively rely (without investigation) on the Certificate Administrator’s tabulation of the majority of the responding Certificateholders.

(ii)         If neither the Initial Requesting Certificateholder, if any, nor any other Certificateholder or Certificate Owner delivers a Preliminary Dispute Resolution Election Notice prior to the Dispute Resolution Cut-off Date, no Certificateholder or Certificate Owner shall have the right to refer the Repurchase Request to mediation or arbitration, and the Enforcing Servicer shall be the sole party entitled to enforce the Trust’s rights against the related Mortgage Loan Seller, subject to the consent or consultation rights of the Directing Holder pursuant to Section 6.08.

(iii)        Promptly and in any event within 10 Business Days following receipt of a Preliminary Dispute Resolution Election Notice from (a) the Initial Requesting Certificateholder, if any, or (b) any other Certificateholder or Certificate Owner (each of clauses (a) and (b), a “Requesting Certificateholder”), the Enforcing Servicer will be required to consult with each Requesting Certificateholder regarding such Requesting Certificateholder’s intention to elect either mediation (including nonbinding arbitration) or arbitration as the dispute resolution method with respect to the Repurchase Request (the “Dispute Resolution Consultation”) so that such Requesting Certificateholder may consider the views of the Enforcing Servicer as to the claims underlying the Repurchase Request and possible dispute resolution methods, such discussions to occur and be completed no later than 10 Business Days following the Dispute Resolution Cut-off Date. The Enforcing Servicer shall be entitled to establish procedures the Enforcing Servicer deems in good faith to be in accordance with the Servicing Standard relating to the timing and extent of such consultations. No later than 5 Business Days after completion of the Dispute Resolution Consultation, a Requesting Certificateholder may provide a final

 -199-

notice to the Enforcing Servicer indicating its decision to exercise its right to refer the matter to either mediation or arbitration (“Final Dispute Resolution Election Notice”).

(iv)        If, following the Dispute Resolution Consultation, no Requesting Certificateholder timely delivers a Final Dispute Resolution Election Notice to the Enforcing Servicer, then the Enforcing Servicer will continue to act as the Enforcing Party and will remain obligated under this Agreement to enforce the rights of the Trust with respect to the Repurchase Request and no Certificateholder or Certificate Owner shall have any further right to elect to refer the matter to mediation or arbitration.

(v)        If a Requesting Certificateholder timely delivers a Final Dispute Resolution Election Notice to the Enforcing Servicer, then such Requesting Certificateholder shall become the Enforcing Party and must promptly submit the matter to mediation (including nonbinding arbitration) or arbitration. If there are more than one Requesting Certificateholder that timely deliver a Final Dispute Resolution Election Notice, then such Requesting Certificateholders will collectively become the Enforcing Party, and the holder or holders of a majority of the Voting Rights among such Requesting Certificateholders will be entitled to make all decisions relating to such mediation or arbitration. If, however, no Requesting Certificateholder commences arbitration or mediation pursuant to the terms of this Agreement within 30 days after delivery of its Final Dispute Resolution Election Notice to the Enforcing Servicer, then (i) the rights of a Requesting Certificateholder to act as the Enforcing Party shall terminate and no Certificateholder or Certificate Owner shall have any further right to elect to refer the matter to mediation or arbitration, (ii) if the Proposed Course of Action Notice indicated that the Enforcing Servicer shall take no further action with respect to the Repurchase Request, then the related Material Defect shall be deemed waived for all purposes under this Agreement and the related Mortgage Loan Purchase Agreement, and (iii) if the Proposed Course of Action Notice had indicated a course of action other than the course of action under clause (ii), then the Enforcing Servicer shall again become the Enforcing Party and, as such, shall be the sole party entitled to enforce the Trust’s rights against the related Mortgage Loan Seller.

(vi)        Notwithstanding the foregoing, the dispute resolution provisions described above under this Section 2.03(l) shall not apply, and the Enforcing Servicer shall remain the Enforcing Party, if the Enforcing Servicer has commenced litigation with respect to the Repurchase Request, or determines in accordance with the Servicing Standard that it is in the best interest of Certificateholders to commence litigation with respect to the Repurchase Request to avoid the running of any applicable statute of limitations.

(vii)       In the event a Requesting Certificateholder becomes the Enforcing Party, the Enforcing Servicer, on behalf of the Trust, shall remain a party to any proceedings against the related Mortgage Loan Seller.

(viii)      For the avoidance of doubt, none of the Depositor, any Mortgage Loan Seller nor any of their respective Affiliates shall be entitled to be an Initial Requesting Certificateholder or a Requesting Certificateholder.

 -200-

(ix)        The Requesting Certificateholder is entitled to elect either mediation or arbitration in its sole discretion; however, the Requesting Certificateholder shall not be entitled to then utilize the alternative method in the event that the initial method is unsuccessful.

(m)      If the Enforcing Party selects mediation (including nonbinding arbitration), the following provisions shall apply:

(i)          The mediation shall be administered by a nationally recognized mediation services provider selected by the related Mortgage Loan Seller (such provider, the “Mediation Services Provider”) in accordance with published mediation procedures (the “Mediation Rules”) promulgated by the Mediation Services Provider.

(ii)         The mediator shall be impartial, an attorney and have at least fifteen (15) years of experience in commercial litigation and either commercial real estate finance or commercial mortgage-backed securitization matters or other complex commercial transactions and who will be appointed from a list of neutrals maintained by the Mediation Services Provider. Upon being supplied a list of at least ten potential mediators by the Mediation Services Provider each party will have the right to exercise two peremptory challenges within fourteen (14) days and to rank the remaining potential mediators in order of preference. The Mediation Services Provider shall select the mediator from the remaining attorneys on the list respecting the preference choices of the parties to the extent possible.

(iii)        The parties shall use commercially reasonable efforts to conduct an organizational conference to begin the mediation within 10 Business Days of the selection of the mediator and to conclude the mediation within 60 days thereafter.

(iv)        The expenses of any mediation will be allocated among the parties to the mediation, including, if applicable, between the Enforcing Party and Enforcing Servicer, as mutually agreed by the parties as part of the mediation.

(n)       If the Enforcing Party selects third-party arbitration, the following provisions will apply:

(i)          The arbitration shall be administered by a nationally recognized arbitration services provider selected by the related Mortgage Loan Seller (such provider, the “Arbitration Services Provider”) in accordance with published arbitration procedures (the “Arbitration Rules”) promulgated by the Arbitration Services Provider.

(ii)         The arbitrator shall be impartial, an attorney and have at least fifteen (15) years of experience in commercial litigation and either commercial real estate finance or commercial mortgage-backed securitization matters or other complex commercial transactions and who will be appointed from a list of neutrals maintained by the Arbitration Services Provider. Upon being supplied a list of at least ten potential arbitrators by the Arbitration Services Provider each party will have the right to exercise two peremptory challenges within fourteen (14) days and to rank the remaining potential arbitrators in order of preference. The Arbitration Services Provider will select the

 -201-

arbitrator from the remaining attorneys on the list respecting the preference choices of the parties to the extent possible.

(iii)        Prior to accepting an appointment, the arbitrator must promptly disclose any circumstances likely to create a reasonable inference of bias or conflict of interest or likely to preclude completion of the hearings within the prescribed time schedule.

(iv)        After consulting with the parties at an organizational conference held not later than 10 Business Days after its appointment, the arbitrator shall devise procedures and deadlines for the arbitration, to the extent not already agreed to by the parties, with the goal of expediting the proceeding and completing the arbitration within 120 days. The arbitrator shall have the authority to schedule, hear, and determine any and all motions, including dispositive and discovery motions, in accordance with the Federal Rules of Civil Procedure for non-jury matters (the “Rules”) (including summary judgment and other prehearing and post hearing motions), and will do so by reasoned decision on the motion of any party to the arbitration.

(v)         Notwithstanding whatever other discovery may be available under the Rules, unless otherwise agreed by the parties, each party to the arbitration will be presumptively limited to the following discovery in the arbitration: (A) the parties shall reasonably and in good faith voluntarily produce to all other parties all documents upon which they intend to rely and all documents they reasonably and in good faith believe to be relevant to the claims or defenses asserted by any of the parties, (B) party witness depositions (excluding Rule 30b-6 witnesses), and (C) expert witness depositions, provided that the arbitrator shall have the ability to grant the parties, or either of them, additional discovery to the extent that the arbitrator determines good cause is shown that such additional discovery is reasonable and necessary.

(vi)        The arbitrator shall make its final determination no later than 30 days after the conclusion of the hearings and submission of any post-hearing submissions. The arbitrator shall resolve the dispute in accordance with the terms of the related Mortgage Loan Purchase Agreement and this Agreement, and may not modify or change those agreements in any way or award remedies not consistent with those agreements. The arbitrator will not have the power to award punitive damages or consequential damages in any arbitration conducted by them. Interest on any monetary award shall bear interest from the date of the Final Dispute Resolution Election Notice at the Prime Rate. In its final determination, the arbitrator shall determine and award the costs of the arbitration (including the fees of the arbitrator, cost of any record or transcript of the arbitration, and administrative fees) and shall award reasonable attorneys’ fees to the parties to the arbitration as determined by the arbitrator in its reasonable discretion. The determination of the arbitrator shall be by a reasoned decision in writing and counterpart copies will be promptly delivered to the parties. The final determination of the arbitrator shall be final and non-appealable, except for actions to confirm or vacate the determination permitted under federal or state law, and may be enforced in any court of competent jurisdiction.

(vii)      By selecting arbitration, the selecting party is giving up the right to sue in court, including the right to a trial by jury.

 -202-

(viii)      No person may bring a putative or certificated class action to arbitration.

(o)       The following provisions will apply to both mediation and third-party arbitration:

(i)          Any mediation or arbitration will be held in New York, New York unless another location is agreed by all parties;

(ii)         If the dispute involves a matter that cannot effectively be remedied by the payment of damages, or if there be any dispute relating to arbitration or the arbitrators that cannot be resolved promptly by the arbitrators or the Arbitration Services Provider, then any party in such instance may during the pendency of the arbitration proceedings seek temporary equitable remedies, pending the final decision of the arbitration panel, solely by application in the Southern District of New York if such court shall have subject matter jurisdiction, or if the Southern District of New York has no jurisdiction, then in the Supreme Court of the State of New York for the County of New York. The arbitration proceedings shall not be stayed unless so ordered by the court.

(iii)       The details and/or existence of any Repurchase Request, any informal meetings, mediations or arbitration proceedings conducted under this Section 2.03, including all offers, promises, conduct and statements, whether oral or written, made in the course of the parties’ attempt to informally resolve any Repurchase Request, will be confidential, privileged and inadmissible for any purpose, including impeachment, in any mediation, arbitration or litigation, or other proceeding (including any proceeding under this Section 2.03). Such information will be kept strictly confidential and shall not be disclosed or shared with any third party (other than a party’s attorneys, experts, accountants and other agents and representatives, as reasonably required in connection with any resolution procedure under this Section 2.03), except as otherwise required by law, regulatory requirement or court order. If any party to a resolution procedure receives a subpoena or other request for information from a third party (other than a governmental regulatory body) for such confidential information, the recipient shall promptly notify the other party to the resolution procedure and shall provide the other party with a reasonable opportunity to object to the production of its confidential information.

(iv)        In the event a Requesting Certificateholder is the Enforcing Party, the agreement with the arbitrator or mediator, as the case may be, shall be required to contain an acknowledgment that the Trust, or the Enforcing Servicer on its behalf, shall be a party to any arbitration or mediation proceedings solely for the purpose of being the beneficiary of any award in favor of the Enforcing Party; provided that the degree and extent to which the Enforcing Servicer actively prepares for and participates in such proceeding shall be determined by such Enforcing Servicer in consultation with the Directing Holder (provided that no Consultation Termination Event has occurred and is continuing and an Excluded Loan is not involved), and in accordance with the Servicing Standard. All amounts recovered by the Enforcing Party shall be paid to the Trust, or the Enforcing Servicer on its behalf, and deposited in the Collection Account. The agreement with the arbitrator or mediator, as the case may be, shall provide that in the event a Requesting Certificateholder is allocated any related costs and expenses pursuant to the terms of the

 -203-

arbitrator’s decision or the agreement reached in mediation, neither the Trust nor the Enforcing Servicer acting on its behalf shall be responsible for any such costs and expenses allocated to the Requesting Certificateholder.

(v)         In the event a Requesting Certificateholder is the Enforcing Party, the Requesting Certificateholder is required to pay any expenses allocated to the Enforcing Party in the arbitration proceedings or any expenses that the Enforcing Party agrees to bear in the mediation proceedings.

(vi)        The Trust (or the Enforcing Servicer or the Trustee, acting on its behalf), the Depositor or any Mortgage Loan Seller shall be permitted to redact any personally identifiable customer information included in any information provided for purposes of any mediation or arbitration. Each party to the proceedings shall be required to agree to keep confidential the details related to the Repurchase Request and the dispute resolution identified in connection with such procedures; provided, however, that the Certificateholders shall be permitted to communicate prior to the commencement of any such proceedings to the extent provided in Section 5.06.

(vii)       For the avoidance of doubt, in no event shall the exercise of any right of a Requesting Certificateholder to refer a Repurchase Request to mediation or arbitration affect in any manner the ability of the Enforcing Servicer to perform its obligations with respect to a Mortgage Loan or the exercise of any rights of a Directing Certificateholder.

(viii)      In the event that the method of dispute resolution selected is unsuccessful, the Requesting Certificateholder may not elect to then utilize the alternative method.

(ix)        Any out-of-pocket expenses required to be borne by the Enforcing Servicer in a mediation or arbitration shall be reimbursable as trust fund expenses.

SERVICING OF THE TRUST FUND

With respect to each Serviced Whole Loan, in the event of a conflict between this Agreement and the related Intercreditor Agreement, the related Intercreditor Agreement shall control; provided that in no event shall the Master Servicer or the Special Servicer, as the case may be, take any action or omit to take any action in accordance with the terms of any Intercreditor Agreement that would cause the Master Servicer or the Special Servicer, as the case may be, to violate the Servicing Standard or the REMIC Provisions. To the extent consistent with the foregoing, the Master Servicer and the Special Servicer shall service the Mortgage Loans (other than any Non-Serviced Mortgage Loan) and the Serviced Companion Loans (including, for the avoidance of doubt, the Trust Subordinate Companion Loans) in accordance with the higher of the following standards of care: (1) in the same manner in which, and with the same care, skill, prudence and diligence with which the Master Servicer or the Special Servicer, as the case may be, services and administers similar mortgage loans for other third party portfolios and (2) the same care, skill, prudence and diligence with which the Master Servicer or the Special Servicer, as the case may be, services and administers similar mortgage loans owned by the Master Servicer or the Special Servicer, as the case may be, with a view to the (A) the timely recovery of all payments of principal and interest under the Mortgage Loans or Serviced Whole Loans or (B) in the case of a Specially Serviced Loan or an REO Property, maximization of timely recovery of principal and interest on a net present value basis on such Mortgage Loans and any related Serviced Companion Loans, and the best interests of the Trust and the Certificateholders (as a collective whole as if such Certificateholders constituted a single lender) (and in the case of any Whole Loan, the best interests of the Trust, the Certificateholders and any related Companion Holder (as a collective whole as if such Certificateholders and the holder or holders of the related Companion Loan constituted a single lender), taking into account the subordinate or pari passu

nature of the related Companion Loan), as determined by the Master Servicer or the Special Servicer, as the case may be, in its reasonable judgment, in either case giving due consideration to the customary and usual standards of practice of prudent institutional commercial, multifamily and manufactured housing community mortgage loan servicers, but without regard to any conflict of interest arising from: (i) any relationship that the Master Servicer, the Special Servicer or any Affiliate of the Master Servicer or the Special Servicer may have with any Mortgagor or any Affiliate of such Mortgagor, any Mortgage Loan Seller, any other parties to this Agreement, any Sponsor, any originator of a Mortgage Loan or any Affiliate of any of the foregoing; (ii) the ownership of any Certificate, Companion Loan, mezzanine loan, or subordinate debt relating to a Mortgage Loan by the Master Servicer, the Special Servicer or any Affiliate of the Master Servicer or the Special Servicer, as applicable; (iii) the obligation, if any, of the Master Servicer to make Advances; (iv) the right of the Master Servicer or the Special Servicer, as the case may be, or any of its Affiliates to receive compensation for its services and reimbursement for its costs hereunder or with respect to any particular transaction; (v) the ownership, servicing or management for others of (a) the Non-Serviced Mortgage Loans and the Non-Serviced Companion Loans or (b) any other mortgage loans, subordinate debt, mezzanine loans or properties not covered by this Agreement or held by the Trust by the Master Servicer or the Special Servicer, as the case may be, or any of its Affiliates; (vi) any debt that the Master Servicer or the Special Servicer, as the case may be, or any of its Affiliates, has extended to any Mortgagor or an Affiliate of any Mortgagor (including, without limitation, any mezzanine financing); (vii) any option to purchase any Mortgage Loan or the related Companion Loan the Master Servicer or the Special Servicer, as the case may be, or any of its Affiliates, may have; and (viii) any obligation of the Master Servicer or the Special Servicer, or any of their respective Affiliates, to repurchase, substitute for or make a Loss of Value Payment with respect to a Mortgage Loan or Trust Subordinate Companion Loan as a Mortgage Loan Seller (if the Master Servicer or the Special Servicer or any of their respective Affiliates is a Mortgage Loan Seller) (the foregoing, collectively referred to as the “Servicing Standard”).

The Master Servicer and the Special Servicer shall act in accordance with the Servicing Standard with respect to any action required to be taken regarding the Non-Serviced Mortgage Loans pursuant to their obligations under this Agreement.

Without limiting the foregoing, subject to Section 3.19, the Special Servicer shall be obligated to service and administer (i) any Mortgage Loans (other than the Non-Serviced Mortgage Loans, except in the case of Section 2.03(f) and Section 2.03(k) through Section 2.03(o)), any related Serviced Companion Loans as to which a Servicing Transfer Event has occurred and is continuing (each, a “Specially Serviced Loan”) or as otherwise provided herein with respect to Non-Specially Serviced Loans in connection with any Major Decision and (ii) any REO Properties (other than the Non-Serviced Mortgaged Properties); provided that the Master Servicer shall continue to receive payments and make all calculations, and prepare, or cause to be prepared, all reports, required hereunder with respect to the Specially Serviced Loans, except for the reports specified herein as prepared by the Special Servicer, as if no Servicing Transfer Event had occurred and with respect to the REO Properties (and the related REO Loans) as if no REO Acquisition had occurred, and to render such services with respect to such Specially Serviced Loans and REO Properties as are specifically provided for herein; provided, further, however, that the Master Servicer shall not be liable for failure to comply with such duties insofar as such failure results from a failure of the Special Servicer to provide

 -207-

sufficient information to the Master Servicer to comply with such duties or failure by the Special Servicer to otherwise comply with its obligations hereunder. The Master Servicer, in its capacity as Master Servicer, will not have any responsibility for the performance by the Special Servicer, in its capacity as Special Servicer, of its duties under this Agreement. The Special Servicer, in its capacity as Special Servicer, will not have any responsibility for the performance by the Master Servicer, in its capacity as Master Servicer, of its duties under this Agreement. Each Mortgage Loan or any related Serviced Companion Loan that becomes a Specially Serviced Loan shall continue as such until satisfaction of the conditions specified in Section 3.19(a). Without limiting the foregoing, subject to Section 3.19, the Master Servicer shall be obligated to service and administer any Non-Specially Serviced Loan or any related Serviced Companion Loan. The Special Servicer shall make the property inspections, use its reasonable efforts to collect the financial statements, budgets, operating statements and rent rolls and forward to the Master Servicer the reports in respect of the related Mortgaged Properties with respect to Specially Serviced Loans in accordance with Section 3.12. After notification to the Master Servicer, the Special Servicer may contact the Mortgagor of any Non-Specially Serviced Loan if efforts by the Master Servicer to collect required financial information have been unsuccessful or any other issues remain unresolved. Such contact shall be coordinated through and with the cooperation of the Master Servicer. No provision herein contained shall be construed as an express or implied guarantee by the Master Servicer or the Special Servicer of the collectability or recoverability of payments on the Mortgage Loans or any related Serviced Companion Loan or shall be construed to impair or adversely affect any rights or benefits provided by this Agreement to the Master Servicer or the Special Servicer (including with respect to Servicing Fees, Special Servicing Fees or the right to be reimbursed for Advances and interest accrued thereon). Any provision in this Agreement for any Advance by the Master Servicer or the Trustee is intended solely to provide liquidity for the benefit of the Certificateholders and not as credit support or otherwise to impose on any such Person the risk of loss with respect to one or more of the Mortgage Loans or any related Serviced Companion Loans. No provision hereof shall be construed to impose liability on the Master Servicer or the Special Servicer for the reason that any recovery to the Certificateholders in respect of a Mortgage Loan at any time after a determination of present value recovery is less than the amount reflected in such determination.

(b)       Subject only to the Servicing Standard and the terms of this Agreement (including, without limitation, Section 6.08) and of the respective Mortgage Loans or any related Serviced Companion Loans and any related Intercreditor Agreement, if applicable, and applicable law, the Master Servicer and the Special Servicer each shall have full power and authority, acting alone or, in the case of the Master Servicer, subject to Section 3.20, through one or more Sub-Servicers, to do or cause to be done any and all things in connection with such servicing and administration for which it is responsible which it may deem necessary or desirable.

If allowed by the related Mortgage Loan documents and applicable law, the Master Servicer may charge the related Mortgagor an administrative fee for maintenance of the Servicing Accounts.

(b)       The Special Servicer, in the case of REO Loans (other than any REO Loan succeeding a Non-Serviced Mortgage Loan), and the Master Servicer, in the case of all other Mortgage Loans (other than a Non-Serviced Mortgage Loan) and each Serviced Companion Loan, shall maintain accurate records with respect to each related Mortgaged Property reflecting the status of real estate taxes, assessments and other similar items that are or may become a lien thereon and the status of insurance premiums and any ground rents payable in respect thereof. The Special Servicer, in the case of REO Loans (other than any REO Loan succeeding a Non-Serviced Mortgage Loan), and the Master Servicer, in the case of all other Mortgage Loans (other than a Non-Serviced Mortgage Loan) and each Serviced Companion Loan, shall use reasonable efforts consistent with the Servicing Standard to obtain, from time to time, all bills for the payment of such items (including renewal premiums) and shall effect payment thereof from the REO Account or by the Master Servicer as Servicing Advances prior to the applicable penalty or termination date and, in any event, prior to the institution of foreclosure or similar proceedings with respect to the related Mortgaged Property for nonpayment of such items, employing for such purpose Escrow Payments (which shall be so applied by the Master Servicer at the written direction of the Special Servicer in the case of REO Loans) as allowed under the terms of the related Mortgage Loan (other than a Non-Serviced Mortgage Loan) and Companion Loan. Other than with respect to any Non-Serviced Mortgage Loan, the Master Servicer shall service and administer any reserve accounts (including monitoring, maintaining or changing the amounts of required escrows) in accordance with the terms of such Mortgage Loan and the related Serviced Companion Loan and the Servicing Standard. To the extent that a Mortgage Loan (other than a Non-Serviced Mortgage Loan) and any related Companion Loan does not require a Mortgagor to escrow for the payment of real estate taxes, assessments, insurance premiums, ground rents (if applicable) and similar items, the Special Servicer, in the case of REO Loans, and the Master Servicer, in the case of all other Mortgage Loans or Companion Loan that it is responsible for servicing hereunder, shall use efforts consistent with the Servicing Standard to cause the Mortgagor to comply with its obligation to make payments in respect of such items at the time they first become due and, in any event, prior to the institution of

 -219-

foreclosure or similar proceedings with respect to the related Mortgaged Property for nonpayment of such items.

(c)       In accordance with the Servicing Standard and for each Mortgage Loan (other than any Non-Serviced Mortgage Loans) and each Serviced Whole Loan, the Master Servicer shall advance all such funds as are necessary for the purpose of effecting the payment of (i) real estate taxes, assessments and other similar items that are or may become a lien thereon, (ii) ground rents (if applicable) and (iii) premiums on Insurance Policies, in each instance if and to the extent Escrow Payments collected from the related Mortgagor (or related REO Revenues, if applicable) are insufficient to pay such item when due and the related Mortgagor has failed to pay such item on a timely basis, and provided, however, that the particular advance would not, if made, constitute a Nonrecoverable Servicing Advance and provided, further, however, that with respect to the payment of taxes and assessments, the Master Servicer shall not be required to make such advance until the later of (i) five (5) Business Days after the Master Servicer, the Special Servicer, the Certificate Administrator or the Trustee, as the case may be, has received confirmation that such item has not been paid and (ii) the date prior to the date after which any penalty or interest would accrue in respect of such taxes or assessments. The Special Servicer shall give the Master Servicer and the Trustee no less than five (5) Business Days’ written (facsimile or electronic) notice before the date on which the Master Servicer is requested to make any Servicing Advance with respect to a given Specially Serviced Loan or REO Property; provided, however, that only two (2) Business Days’ written (facsimile or electronic) notice shall be required in respect of Servicing Advances required to be made on an emergency or urgent basis provided, further, that the Special Servicer shall not be entitled to make such a request (other than for Servicing Advances required to be made on an urgent or emergency basis) more frequently than once per calendar month (although such request may relate to more than one Servicing Advance). The Master Servicer may pay the aggregate amount of such Servicing Advances listed on a monthly request to the Special Servicer, in which case the Special Servicer shall remit such Servicing Advances to the ultimate payees. The Special Servicer shall have no obligation to make any Servicing Advances; provided that in an urgent or emergency situation requiring the making of a Servicing Advance, the Special Servicer may make a Servicing Advance. Within five (5) Business Days of making such a Servicing Advance, the Special Servicer shall deliver to the Master Servicer request for reimbursement for such Servicing Advance, along with all information and documentation in the Special Servicer’s possession regarding the subject Servicing Advance as the Master Servicer may reasonably request, and the Master Servicer shall be obligated, out of such Master Servicer’s own funds, to reimburse the Special Servicer for any unreimbursed Servicing Advances (other than Nonrecoverable Servicing Advances) made by the Special Servicer pursuant to the terms hereof), together with interest thereon at the Reimbursement Rate from the date made to, but not including, the date of reimbursement. Such reimbursement and any accompanying payment of interest shall be made within five (5) Business Days of the written request therefor pursuant to the preceding sentence by wire transfer of immediately available funds to an account designated in writing by the Special Servicer. Upon the Master Servicer’s reimbursement to the Special Servicer of any Servicing Advance and payment to the Special Servicer of interest thereon, all in accordance with this Section 3.03, the Master Servicer shall for all purposes of this Agreement be deemed to have made such Servicing Advance at the same time as the Special Servicer actually made such Servicing Advance, and accordingly, the Master Servicer shall be entitled to be reimbursed for such Servicing Advance, together with interest thereon at the Reimbursement Rate, at the same

 -220-

time, in the same manner and to the same extent as the Master Servicer would otherwise have been entitled if it had actually made such Servicing Advance at the time the Special Servicer did. Notwithstanding the foregoing provisions of this Section 3.03, the Master Servicer shall not be required to reimburse the Special Servicer for any such Servicing Advance if the Master Servicer determines in accordance with the Servicing Standard that such Servicing Advance, although not characterized by the Special Servicer as a Nonrecoverable Servicing Advance, is in fact a Nonrecoverable Servicing Advance. The Master Servicer shall notify the Special Servicer in writing of such determination and, if applicable, such Nonrecoverable Servicing Advance shall be reimbursed to the Special Servicer pursuant to Section 3.05 of this Agreement.

Any request by the Special Servicer that the Master Servicer make a Servicing Advance shall be deemed to be a determination by the Special Servicer that such requested Servicing Advance is not a Nonrecoverable Servicing Advance, and the Master Servicer shall be entitled to conclusively rely on such determination, provided that the determination shall not be binding on the Master Servicer or Trustee. On the first Business Day after the Determination Date for the related Distribution Date, the Special Servicer shall report to the Master Servicer if the Special Servicer determines any Servicing Advance previously made by the Master Servicer with respect to a Specially Serviced Loan or REO Loan is a Nonrecoverable Servicing Advance. The Master Servicer shall be entitled to conclusively rely on such a determination, but such determination shall not be binding upon the Master Servicer, and shall in no way limit the ability of the Master Servicer in the absence of such determination to make its own determination that any Advance is a Nonrecoverable Advance. If the Special Servicer makes a determination that only a portion of, and not all of, any previously made or proposed Servicing Advance is a Nonrecoverable Advance, the Master Servicer shall have the right to make its own subsequent determination that any remaining portion of any such previously made or proposed Servicing Advance is a Nonrecoverable Advance. All such Advances shall be reimbursable in the first instance from related collections from the Mortgagors and further as provided in Section 3.05(a). No costs incurred by the Master Servicer or the Special Servicer in effecting the payment of real estate taxes, assessments and, if applicable, ground rents on or in respect of the Mortgaged Properties shall, for purposes hereof, including, without limitation, the Certificate Administrator’s calculation of monthly distributions to Certificateholders, be added to the unpaid principal balances of the related Mortgage Loans or any related Serviced Companion Loan, if applicable, notwithstanding that the terms of such Mortgage Loans or related Serviced Companion Loan, if applicable, so permit. If the Master Servicer fails to make any required Servicing Advance as and when due (including any applicable cure periods), to the extent the Trustee has actual knowledge of such failure, the Trustee shall make such Servicing Advance pursuant to Section 7.05. Notwithstanding anything herein to the contrary, no Servicing Advance shall be required hereunder if such Servicing Advance would, if made, constitute a Nonrecoverable Servicing Advance. In addition, the Master Servicer shall consider Unliquidated Advances in respect of prior Servicing Advances for purposes of nonrecoverability determinations. The Special Servicer shall have no obligation to make any Servicing Advances under this Agreement.

Notwithstanding the foregoing provisions of this Section 3.03(c), the Master Servicer shall not be required to reimburse the Special Servicer out of its own funds for, or to make at the direction of the Special Servicer, any Servicing Advance if the Master Servicer determines that such Servicing Advance, although not characterized by the Special Servicer as a

 -221-

Nonrecoverable Servicing Advance, is a Nonrecoverable Servicing Advance. The Master Servicer shall notify the Special Servicer in writing of such determination and, if applicable, such Nonrecoverable Servicing Advance shall be reimbursed to the Special Servicer pursuant to Section 3.05(a).

Notwithstanding anything to the contrary contained in this Section 3.03(c), the Master Servicer may in its good faith judgment elect (but shall not be required unless directed by the Special Servicer with respect to Specially Serviced Loans and REO Loans) to make a payment from amounts on deposit in the Collection Account (or any Companion Distribution Account maintained as a subaccount thereof by a Companion Paying Agent, if applicable) (which shall be deemed first made from amounts distributable as principal and then from all other amounts comprising general collections) to pay for certain expenses set forth below notwithstanding that the Master Servicer (or the Special Servicer, as applicable) has determined that a Servicing Advance with respect to such expenditure would be a Nonrecoverable Servicing Advance (unless, with respect to Specially Serviced Loans or REO Loans, the Special Servicer has notified the Master Servicer to not make such expenditure), where making such expenditure would prevent (i) the related Mortgaged Property from being uninsured or being sold at a tax sale or (ii) any event that would cause a loss of the priority of the lien of the related Mortgage, or the loss of any security for the related Mortgage Loan or Serviced Companion Loan; provided that in each instance, the Master Servicer or the Special Servicer, as applicable, determines in accordance with the Servicing Standard (as evidenced by an Officer’s Certificate delivered to the Trustee) that making such expenditure is in the best interest of the Certificateholders (and, if applicable, the Companion Holders), all as a collective whole (taking into account the subordinate or pari passu nature of any Companion Loans, as the case may be). The Master Servicer or Trustee may elect to obtain reimbursement of Nonrecoverable Servicing Advances from the Trust pursuant to the terms of Section 3.17(c). The parties acknowledge that pursuant to the applicable Non-Serviced PSA, the applicable Non-Serviced Master Servicer is obligated to make servicing advances with respect to the related Non-Serviced Whole Loan. The applicable Non-Serviced Master Servicer shall be entitled to reimbursement for Nonrecoverable Servicing Advances with respect to such Non-Serviced Whole Loan (with, in each case, any accrued and unpaid interest thereon provided for under the applicable Non-Serviced PSA) in the manner set forth in the applicable Non-Serviced PSA and the applicable Non-Serviced Intercreditor Agreement.

(d)       In connection with its recovery of any Servicing Advance out of the Collection Account (or any Companion Distribution Account maintained as a subaccount thereof by the Companion Paying Agent, if applicable) pursuant to Section 3.05(a), the Trustee, the Special Servicer and then the Master Servicer, as the case may be and in that order, shall be entitled to receive, out of any amounts then on deposit in the Collection Account interest at the Reimbursement Rate in effect from time to time, accrued on the amount of such Servicing Advance from the date made to, but not including, the date of reimbursement. Subject to Section 3.17(c), the Master Servicer shall reimburse itself, the Special Servicer or the Trustee, as the case may be, for any outstanding Servicing Advance as soon as practically possible after funds available for such purpose are deposited in the Collection Account (or any Companion Distribution Account maintained as a subaccount thereof by the Companion Paying Agent, if applicable) subject to the Master Servicer’s or the Trustee’s options and rights to defer recovery of such amounts as provided herein; provided, however, that such Master Servicer’s or Trustee’s

 -222-

options and rights to defer recovery of such amounts shall not alter the Master Servicer’s obligation to reimburse the Special Servicer for any outstanding Servicing Advance as provided for in this sentence. To the extent amounts on deposit in the Companion Distribution Account with respect to the related Companion Loan are insufficient for any such reimbursement, the Master Servicer shall use reasonable efforts in accordance with the Servicing Standard to enforce the rights of the holder of the related Mortgage Loan under the related Intercreditor Agreement to obtain any reimbursement available from the holder of the related Companion Loan.

(e)       To the extent an operations and maintenance plan is required to be established and executed pursuant to the terms of a Mortgage Loan (other than a Non-Serviced Mortgage Loan) or Trust Subordinate Companion Loan, the Master Servicer shall request from the Mortgagor written confirmation thereof within a reasonable time after the later of the Closing Date and the date as of which plan is required to be established or completed. To the extent any repairs, capital improvements, actions or remediations are required to have been taken or completed pursuant to the terms of the Mortgage Loan (other than a Non-Serviced Mortgage Loan) or Trust Subordinate Companion Loan, the Master Servicer shall request from the Mortgagor written confirmation of such actions and remediations within a reasonable time after the later of the Closing Date and the date as of which action or remediations are required to be or to have been taken or completed. To the extent a Mortgagor shall fail to promptly respond to any inquiry described in this Section 3.03(e), the Master Servicer shall report any such failure to the Special Servicer within a reasonable time after the date as of which actions or remediations are required to be or to have been taken or completed.

(vii)       any amounts required to be deposited by the Master Servicer or the Special Servicer pursuant to Section 3.07(b) in connection with losses resulting from a deductible clause in a blanket hazard or master single interest policy.

Notwithstanding the foregoing requirements, the Master Servicer need not deposit into the Collection Account any amount that the Master Servicer would be authorized to withdraw immediately from such account in accordance with the terms of Section 3.05 and shall be entitled to instead immediately pay such amount directly to the Person(s) entitled thereto; provided that such amounts shall be applied in accordance with the terms hereof and shall be reported as if deposited in such Collection Account and then withdrawn.

The foregoing requirements for deposit in the Collection Account shall be exclusive, it being understood and agreed that, without limiting the generality of the foregoing, actual payments from Mortgagors in the nature of Escrow Payments, charges for beneficiary statements or demands, assumption fees, modification fees, extension fees, defeasance fees, amounts collected for Mortgagor checks returned for insufficient funds or other amounts the Master Servicer or the Special Servicer would be entitled to retain as additional servicing compensation need not be deposited by the Master Servicer in the Collection Account. If the Master Servicer shall deposit in the Collection Account any amount not required to be deposited therein, it may at any time withdraw such amount from the Collection Account, any provision herein to the contrary notwithstanding. Assumption, extension and modification fees actually received from Mortgagors on Specially Serviced Loans shall be promptly delivered to the Special Servicer as additional servicing compensation.

 -224-

Upon receipt of any of the foregoing amounts in clauses (i) through (iv) above with respect to any Specially Serviced Loans, the Special Servicer shall remit within one (1) Business Day such amounts to the Master Servicer for deposit into the Collection Account, in accordance with this Section 3.04(a). Any such amounts received by the Special Servicer with respect to an REO Property shall be deposited by the Special Servicer into the REO Account and remitted to the Master Servicer for deposit into the Collection Account, pursuant to Section 3.14(c).

For purposes of determining amounts to be deposited in the Collection Account in respect of any Trust Subordinate Companion Loan and the related Mortgage Loan, the Master Servicer shall determine the allocation of such amounts in accordance with the related Intercreditor Agreement.

All such Permitted Investments shall be held to maturity, unless payable on demand. Any funds held in an Investment Account shall be held in the name of the Master Servicer or the Special Servicer, as applicable, on behalf of the Trustee (in its capacity as such) for the benefit of the Certificateholders. The Master Servicer (in the case of the Collection Account, the Companion Distribution Account or any Servicing Account maintained by or for the Master Servicer), the Special Servicer (in the case of the REO Account, Loss of Value Reserve Fund or any Servicing Account maintained by or for the Special Servicer) on behalf of the Trustee, shall maintain continuous physical possession of any Permitted Investment of amounts in the Collection Account, the Companion Distribution Account, the Servicing Accounts, the Loss of Value Reserve Fund or the REO Account, as applicable, that is either (i) a “certificated security,” as such term is defined in the UCC (such that the Trustee shall have control pursuant to Section 8-106 of the UCC) or (ii) other property in

 -246-

which a secured party may perfect its security interest by physical possession under the UCC or any other applicable law. In the case of any Permitted Investment held in the form of a “security entitlement” (within the meaning of Section 8-102(a)(17) of the UCC), the Master Servicer or the Special Servicer, as applicable, shall take or cause to be taken such action as the Trustee deems reasonably necessary to cause the Trustee to have control over such security entitlement. In the event amounts on deposit in an Investment Account are at any time invested in a Permitted Investment payable on demand, the Master Servicer (in the case of the Collection Account, the Companion Distribution Account or any Servicing Account maintained by or for the Master Servicer) or the Special Servicer (in the case of the REO Account or any Servicing Account maintained by or for the Special Servicer) shall:

(i)          consistent with any notice required to be given thereunder, demand that payment thereon be made on the last day such Permitted Investment may otherwise mature hereunder in an amount equal to the lesser of (a) all amounts then payable thereunder and (b) the amount required to be withdrawn on such date; and

(ii)         demand payment of all amounts due thereunder promptly upon determination by the Master Servicer, the Special Servicer, the Certificate Administrator or the Trustee, as the case may be, that such Permitted Investment would not constitute a Permitted Investment in respect of funds thereafter on deposit in the Investment Account.

(b)         Interest and investment income realized on funds deposited in the Collection Account, the Companion Distribution Account or any Servicing Account maintained by or for the Master Servicer to the extent of the Net Investment Earnings, if any, with respect to such account for the period from and including the prior Distribution Date to and including the P&I Advance Date related to the current Distribution Date, shall be for the sole and exclusive benefit of the Master Servicer to the extent (with respect to Servicing Accounts) not required to be paid to the related Mortgagor and shall be subject to its withdrawal, or withdrawal at its direction, in accordance with Section 3.03 or Section 3.05(a), as the case may be. Interest and investment income realized on funds deposited in the REO Account, Loss of Value Reserve Fund or any Servicing Account maintained by or for the Special Servicer, to the extent of the Net Investment Earnings, if any, with respect to such account for each period from and including any Distribution Date to and including the immediately succeeding P&I Advance Date, shall be for the sole and exclusive benefit of the Special Servicer and shall be subject to its withdrawal in accordance with Section 3.14(c). In the event that any loss shall be incurred in respect of any Permitted Investment (as to which the Master Servicer or the Special Servicer, as applicable, would have been entitled to any Net Investment Earnings hereunder) directed to be made by the Master Servicer or the Special Servicer, as applicable, and on deposit in any of the Collection Account, the Companion Distribution Account, the Servicing Account, Loss of Value Reserve Fund or the REO Account, the Master Servicer (in the case of the Collection Account, the Companion Distribution Account or any Servicing Account maintained by or for the Master Servicer), the Special Servicer (in the case of the REO Account, Loss of Value Reserve Fund or any Servicing Account maintained by or for the Special Servicer) shall deposit therein, no later than the P&I Advance Date, without right of reimbursement, the amount of Net Investment Loss, if any, with respect to such account for the period from and including the prior Distribution Date to and including the P&I Advance Date related to the current Distribution Date; provided that neither the Master Servicer nor the Special Servicer shall be required to deposit any loss on an

 -247-

investment of funds in an Investment Account if such loss is incurred solely as a result of the insolvency of the federal or state chartered depository institution or trust company that holds such Investment Account, so long as such depository institution or trust company satisfied the qualifications set forth in the definition of Eligible Account at the time such investment was made (and, with respect to the Master Servicer or the Special Servicer, such federal or state chartered depository institution or trust company is not an Affiliate of the Master Servicer or the Special Servicer, as applicable, unless such depository institution or trust company satisfied the qualification set forth in the definition of Eligible Account both (x) at the time the investment was made and (y) thirty (30) days prior to such insolvency).

(c)         Except as otherwise expressly provided in this Agreement, if any default occurs in the making of a payment due under any Permitted Investment, or if a default occurs in any other performance required under any Permitted Investment, the Master Servicer may and, upon the request of Holders of Certificates entitled to a majority of the Voting Rights allocated to any Class shall, take such action as may be appropriate to enforce such payment or performance, including the institution and prosecution of appropriate proceedings.

Section 3.07     Maintenance of Insurance Policies; Errors and Omissions and Fidelity Coverage.   (a) To the extent permitted by the related Mortgage Loan documents and required by the Servicing Standard, the Master Servicer (with respect to the Mortgage Loans (other than a Non-Serviced Mortgage Loan) and any related Serviced Companion Loan) shall use efforts consistent with the Servicing Standard to cause the Mortgagor to maintain (other than with respect to a Non-Serviced Mortgage Loan), and the Special Servicer (with respect to REO Properties other than any Non-Serviced Mortgaged Properties) shall maintain all insurance coverage as is required under the related Mortgage Loan documents except to the extent that the failure of the related Mortgagor to do so is an Acceptable Insurance Default (and except as provided in the next sentence with respect to the Master Servicer or the Special Servicer, as applicable). If the Mortgagor does not so maintain such insurance coverage, subject to its recoverability determination with respect to any required Servicing Advance, the Master Servicer (with respect to the Mortgage Loans (other than a Non-Serviced Mortgage Loan) and any related Serviced Companion Loan) or the Special Servicer (with respect to REO Properties other than a Non-Serviced Mortgaged Property) shall maintain all insurance coverage as is required under, and such insurance coverage is to be obtained from an insurer meeting the requirements under, the related Mortgage Loan documents, but only in the event the Trustee has an insurable interest therein and such insurance is available to the Master Servicer or the Special Servicer and, if available, can be obtained at commercially reasonable rates. Any determination that such insurance coverage is not available or not available at commercially reasonable rates shall be made with the consent of the Directing Holder (prior to the occurrence and continuance of any Control Termination Event) and, after consultation by the Special Servicer with the Risk Retention Consultation Party pursuant to Section 6.08(a) (in the case of the Directing Holder and Risk Retention Consultation Party, other than with respect to any Excluded Loan as to such party). Such determination shall be made by the Master Servicer (with respect to the Mortgage Loans (other than a Non-Serviced Mortgage Loan) and any related Serviced Companion Loan) or the Special Servicer (with respect to REO Properties other than any Non-Serviced Mortgaged Property) except to the extent that the failure of the related Mortgagor to do so is an Acceptable Insurance Default as determined by the Special Servicer; provided, however, that if any Mortgage permits the holder thereof to dictate to the Mortgagor the insurance coverage to be

 -248-

maintained on such Mortgaged Property, the Master Servicer or, with respect to an REO Property, the Special Servicer, as applicable, shall impose or maintain, as applicable, such insurance requirements as are consistent with the Servicing Standard taking into account the insurance in place at the closing of the Mortgage Loan or Trust Subordinate Companion Loan, provided that if any Mortgage Loan documents permit the holder thereof to dictate to the Mortgagor the insurance coverage to be maintained on such Mortgaged Property, the Master Servicer or, with respect to a REO Property, the Special Servicer will impose or maintain such insurance requirements as are consistent with the Servicing Standard taking into account the insurance in place at the origination of the Mortgage Loan or Trust Subordinate Companion Loan; provided, further, that, with respect to the immediately preceding proviso, the Master Servicer shall be obligated to use efforts consistent with the Servicing Standard to cause the Mortgagor to maintain (or to itself maintain) insurance against property damage resulting from terrorist or similar acts unless the Mortgagor’s failure is an Acceptable Insurance Default (as determined by the Special Servicer with the consent of the Directing Holder (unless a Control Termination Event has occurred) and after consultation by the Special Servicer with the Risk Retention Consultation Party pursuant to Section 6.08(a) (in each case, other than with respect to any Excluded Loan as to such party) and only in the event the Trustee has an insurable interest therein and such insurance is available to the Master Servicer or the Special Servicer, as the case may be, and, if available, can be obtained at commercially reasonable rates. The Master Servicer and the Special Servicer shall be entitled to rely on insurance consultants (at the applicable servicer’s expense) in determining whether any insurance is available at commercially reasonable rates. Subject to Section 3.15(a) and the costs of such insurance being reimbursed or paid to the Special Servicer as provided in the third-to-last sentence of this paragraph, the Special Servicer shall maintain (except to the extent that the failure to maintain such insurance coverage is an Acceptable Insurance Default) for each REO Property (other than any Non-Serviced Mortgaged Property) no less insurance coverage than was previously required of the Mortgagor under the related Mortgage Loan documents unless the Special Servicer determines with the consent of the Directing Holder (prior to the occurrence and continuance of a Control Termination Event) and after consultation by the Special Servicer with the Risk Retention Consultation Party pursuant to Section 6.08(a) (in each case, other than with respect to a Mortgage Loan that is an Excluded Loan as to such party) that such insurance is not available at commercially reasonable rates or that the Trustee does not have an insurable interest, in which case the Master Servicer shall be entitled to conclusively rely on the Special Servicer’s determination. All Insurance Policies maintained by the Master Servicer or the Special Servicer shall (i) contain a “standard” mortgagee clause, with loss payable to the Master Servicer on behalf of the Trustee (in the case of insurance maintained in respect of Mortgage Loans (other than any Non-Serviced Mortgage Loan), including any related Serviced Companion Loan, other than REO Properties) or to the Special Servicer on behalf of the Trustee (in the case of insurance maintained in respect of REO Properties), (ii) be in the name of the Trustee (in the case of insurance maintained in respect of REO Properties), (iii) include coverage in an amount not less than the lesser of (x) the full replacement cost of the improvements securing Mortgaged Property or the REO Property, as applicable, and (y) the outstanding principal balance owing on the related Mortgage Loan (including any related Serviced Companion Loan) or REO Loan, as applicable, and in any event, the amount necessary to avoid the operation of any co-insurance provisions, (iv) include a replacement cost endorsement providing no deduction for depreciation (unless such endorsement is not permitted under the related Mortgage Loan documents), (v) be

 -249-

noncancelable without thirty (30) days prior written notice to the insured party (except in the case of nonpayment, in which case such policy shall not be cancelled without ten (10) days prior notice) and (vi) subject to the first proviso in the second sentence of this Section 3.07(a), be issued by a Qualified Insurer authorized under applicable law to issue such Insurance Policies. Any amounts collected by the Master Servicer or the Special Servicer under any such Insurance Policies (other than amounts to be applied to the restoration or repair of the related Mortgaged Property or REO Property or amounts to be released to the related Mortgagor, in each case in accordance with the Servicing Standard and the provisions of the related Mortgage Loan documents) shall be deposited in the Collection Account, subject to withdrawal pursuant to Section 3.05(a). Any costs incurred by the Master Servicer in maintaining any such Insurance Policies in respect of Mortgage Loans (including any related Serviced Companion Loan) (other than REO Properties and other than any Non-Serviced Mortgage Loan) (i) if the Mortgagor defaults on its obligation to do so, shall be advanced by the Master Servicer as a Servicing Advance (so long as such Advance would not be a Nonrecoverable Advance and if such Advance would be a Nonrecoverable Advance then such cost shall instead be paid out of the Collection Account) and will be charged to the related Mortgagor and (ii) shall not, for purposes of calculating monthly distributions to Certificateholders, be added to the unpaid principal balance of the related Mortgage Loan and Serviced Companion Loan (if any), notwithstanding that the terms of such Mortgage Loan or Serviced Companion Loan so permit. Any cost incurred by the Special Servicer in maintaining any such Insurance Policies with respect to REO Properties shall be an expense of the Trust payable out of the related REO Account pursuant to Section 3.14(c) or, if the amount on deposit therein is insufficient therefor, advanced by the Master Servicer as a Servicing Advance (so long as such Advance would not be a Nonrecoverable Advance and if such Advance would be a Nonrecoverable Advance then such cost shall instead be paid out of the Collection Account). The foregoing provisions of this Section 3.07 shall apply to any Serviced Whole Loan as if it were a single “Mortgage Loan”. Notwithstanding any provision to the contrary, the Master Servicer shall not be required to maintain, and shall not be in default for failing to obtain, any earthquake or environmental insurance on any Mortgaged Property unless such insurance was required at the time of origination of the related Mortgage Loan and is currently available at commercially reasonable rates.

Notwithstanding the foregoing, with respect to the Mortgage Loans (other than a Non-Serviced Mortgage Loan) and any related Serviced Companion Loan that either (x) require the Mortgagor to maintain “all risk” property insurance (and do not expressly permit an exclusion for terrorism) or (y) contain provisions generally requiring the applicable Mortgagor to maintain insurance in types and against such risks as the holder of such Mortgage Loan (including any related Serviced Companion Loan) reasonably requires from time to time in order to protect its interests, the Master Servicer shall be consistent with the Servicing Standard, (A) monitor in accordance with the Servicing Standard whether the insurance policies for the related Mortgaged Property contain Additional Exclusions (provided that the Master Servicer will be entitled to conclusively rely upon the certificates of insurance in determining whether such policies contain Additional Exclusions), (B) request the Mortgagor to either purchase insurance against the risks specified in the Additional Exclusions or provide an explanation as to its reasons for failing to purchase such insurance and (C) notify the Special Servicer if it has knowledge that any insurance policy contains Additional Exclusions or if it has knowledge (such knowledge to be based upon the Master Servicer’s compliance with the immediately preceding

 -250-

clauses (A) and (B) above) that any Mortgagor fails to purchase the insurance requested to be purchased by the Master Servicer pursuant to clause (B) above. If the Special Servicer determines in accordance with the Servicing Standard that such failure is not an Acceptable Insurance Default, the Special Servicer shall notify the Master Servicer and the Master Servicer shall use efforts consistent with the Servicing Standard to cause such insurance to be maintained. The Special Servicer (at the expense of the Trust) shall be entitled to rely on insurance consultants in making such determinations. The Master Servicer shall be entitled to rely on insurance consultants (at the expense of such Master Servicer) in determining whether Additional Exclusions exist. Furthermore, the Special Servicer shall promptly deliver such conclusions in writing to the 17g-5 Information Provider for posting to the 17g-5 Information Provider’s Website for those Mortgage Loans that (i) have one of the ten (10) highest outstanding Stated Principal Balances of all of the Mortgage Loans then included in the Trust or (ii) comprise more than 5% of the outstanding Stated Principal Balance of the Mortgage Loans then included in the Trust. During the period that the Special Servicer is evaluating the availability of such insurance or waiting for a response from the Directing Holder, or with respect to a Serviced AB Whole Loan, the holder of the related Subordinate Companion Loan, or to consult with the Risk Retention Consultation Party pursuant to Section 6.08(a), neither the Master Servicer nor the Special Servicer will be liable for any loss related to its failure to require the Mortgagor to maintain (or its failure to maintain) such insurance and shall not be in default of its obligations as a result of such failure unless the Master Servicer or the Special Servicer is required to take any immediate action pursuant to the Servicing Standard or other servicing requirements of this Agreement and the Master Servicer will not itself maintain such insurance or cause such insurance to be maintained.

(b)         (i) If the Master Servicer or the Special Servicer shall obtain and maintain a blanket Insurance Policy with a Qualified Insurer insuring against fire and hazard losses on all of the Mortgage Loans (including any related Serviced Companion Loan, but excluding any Non-Serviced Mortgage Loan) or REO Properties (other than with respect to a Non-Serviced Mortgaged Property), as the case may be, required to be serviced and administered hereunder, then, to the extent such Insurance Policy provides protection equivalent to the individual policies otherwise required, the Master Servicer or the Special Servicer shall conclusively be deemed to have satisfied its obligation to cause fire and hazard insurance to be maintained on the related Mortgaged Properties or REO Properties. Such Insurance Policy may contain a deductible clause, in which case the Master Servicer or the Special Servicer shall, if there shall not have been maintained on the related Mortgaged Property or REO Property a fire and hazard Insurance Policy complying with the requirements of Section 3.07(a), and there shall have been one or more losses which would have been covered by such Insurance Policy, promptly deposit into the Collection Account from its own funds the amount of such loss or losses that would have been covered under the individual policy but are not covered under the blanket Insurance Policy because of such deductible clause to the extent that any such deductible exceeds the deductible limitation that pertained to the related Mortgage Loan (including any related Serviced Companion Loan), or in the absence of such deductible limitation, the deductible limitation which is consistent with the Servicing Standard. In connection with its activities as administrator and Master Servicer of the Mortgage Loans or any Serviced Companion Loans, the Master Servicer agrees to prepare and present, on behalf of itself, the Trustee and Certificateholders, claims under any such blanket Insurance Policy in a timely fashion in accordance with the terms of such policy. Consistent with subsection (a) above, the Special Servicer, to the extent

 -251-

consistent with the Servicing Standard, may maintain, earthquake insurance on REO Properties (other than with respect to a Non-Serviced Mortgaged Property), provided coverage is available at commercially reasonable rates, the cost of which shall be a Servicing Advance.

(ii)         If the Master Servicer or the Special Servicer shall cause any Mortgaged Property or REO Property to be covered by a master single interest or force-placed insurance policy with a Qualified Insurer naming the Master Servicer or the Special Servicer on behalf of the Trustee as the loss payee, then to the extent such Insurance Policy provides protection equivalent to the individual policies otherwise required, the Master Servicer or the Special Servicer shall conclusively be deemed to have satisfied its obligation to cause such insurance to be maintained on the related Mortgaged Properties and REO Properties. In the event the Master Servicer or the Special Servicer shall cause any Mortgaged Property or REO Property to be covered by such master single interest or force-placed insurance policy, the incremental costs of such insurance applicable to such Mortgaged Property or REO Property (i.e., other than any minimum or standby premium payable for such policy whether or not any Mortgaged Property or REO Property is covered thereby) shall be paid by the Master Servicer as a Servicing Advance. Such master single interest or force-placed policy may contain a deductible clause, in which case the Master Servicer or the Special Servicer shall, in the event that there shall not have been maintained on the related Mortgaged Property or REO Property a policy otherwise complying with the provisions of Section 3.07(a), and there shall have been one or more losses which would have been covered by such policy had it been maintained, deposit into the Collection Account from its own funds the amount not otherwise payable under the master single or force-placed interest policy because of such deductible clause, to the extent that any such deductible exceeds the deductible limitation that pertained to the related Mortgage Loan, including any related Serviced Companion Loan, or, in the absence of any such deductible limitation, the deductible limitation which is consistent with the Servicing Standard.

(c)         Each of the Master Servicer and the Special Servicer shall obtain and maintain at its own expense and keep in full force and effect throughout the term of this Agreement a blanket fidelity bond and an errors and omissions insurance policy with a Qualified Insurer covering the Master Servicer’s and the Special Servicer’s, as applicable, officers and employees acting on behalf of the Master Servicer and the Special Servicer in connection with its activities under this Agreement. Notwithstanding the foregoing, so long as the long-term debt or the deposit obligations or claims-paying ability of the Master Servicer (or its immediate or remote parent) or the Special Servicer (or its immediate or remote parent), as applicable, is rated at least “A3” by Moody’s, “A(low)” by DBRS (if rated by DBRS) and “A-” by Fitch (if rated by Fitch), the Master Servicer (or its public parent) or the Special Servicer (or its public parent), as applicable, shall be allowed to provide self-insurance with respect to a fidelity bond and an “errors and omissions” Insurance Policy. Such amount of coverage shall be in such form and amount as are consistent with the Servicing Standard. Coverage of the Master Servicer or the Special Servicer under a policy or bond obtained by an Affiliate of the Master Servicer or the Special Servicer and providing the coverage required by this Section 3.07(c) shall satisfy the requirements of this Section 3.07(c). The Special Servicer and the Master Servicer will promptly report in writing to the Trustee any material changes that may occur in their respective fidelity bonds, if any, and/or their respective errors and omissions insurance policies, as the case may be,

 -252-

and will furnish to the Trustee evidence that such bonds, if any, and insurance policies are in full force and effect.

(d)         At the time the Master Servicer determines in accordance with the Servicing Standard that any Mortgaged Property (other than a Non-Serviced Mortgaged Property) is in a federally designated special flood hazard area (and such flood insurance has been made available), the Master Servicer will use efforts consistent with the Servicing Standard to cause the related Mortgagor (in accordance with applicable law and the terms of the Mortgage Loan and related Serviced Companion Loan documents) to maintain, and, if the related Mortgagor shall default in its obligation to so maintain, shall itself maintain to the extent available at commercially reasonable rates (as determined by the Master Servicer in accordance with the Servicing Standard) and to the extent the Trustee, as mortgagee, has an insurable interest therein, flood insurance in respect thereof. Such flood insurance shall be in an amount equal to the lesser of (i) the unpaid principal balance of the related Mortgage Loan (and any related Serviced Companion Loan, if applicable), and (ii) the maximum amount of insurance which is available under the National Flood Insurance Act of 1968, as amended, plus such additional excess flood coverage with respect to the Mortgaged Property, if any, in an amount consistent with the Servicing Standard, but only to the extent the related Mortgage Loan (other than a Non-Serviced Mortgage Loan) or related Serviced Companion Loan permits the mortgagee to require such coverage and the maintenance of such coverage is consistent with the Servicing Standard. If the cost of any insurance described above is not borne by the Mortgagor, the Master Servicer shall promptly make a Servicing Advance for such costs.

(e)         During all such times as any REO Property (other than with respect to a Non Serviced Mortgaged Property) shall be located in a federally designated special flood hazard area, the Special Servicer will cause to be maintained, to the extent available at commercially reasonable rates (as determined by the Special Servicer (with the consent of the Directing Holder (prior to the occurrence and continuance of a Control Termination Event) and in consultation with the Risk Retention Consultation Party pursuant to Section 6.08(a) (in either such case, other than with respect to any Mortgage Loan that is an Excluded Loan as to such party)) in accordance with the Servicing Standard), a flood insurance policy meeting the requirements of the current guidelines of the Federal Insurance Administration in an amount representing coverage not less than the maximum amount of insurance which is available under the National Flood Insurance Act of 1968, as amended. The cost of any such flood insurance with respect to an REO Property shall be an expense of the Trust payable out of the related REO Account pursuant to Section 3.14(c) or, if the amount on deposit therein is insufficient therefor, paid by the Master Servicer as a Servicing Advance.

(f)          Each of the Operating Advisor and Asset Representations Reviewer shall obtain and maintain at its own expense and keep in full force and effect throughout the term of this Agreement an “errors and omissions” insurance policy with a Qualified Insurer covering losses that may be sustained as a result of an officer’s or employee’s errors or omissions.

Section 3.08     Enforcement of Due-on-Sale Clauses; Assumption Agreements.   (a) As to each Mortgage Loan (other than a Non-Serviced Mortgage Loan) and any related Serviced Companion Loan that contains a provision in the nature of a “due-on-sale” clause, which by its terms:

 -253-

(i)          provides that such Mortgage Loan and any related Companion Loan shall (or may at the mortgagee’s option) become due and payable upon the sale or other transfer of an interest in the related Mortgaged Property or equity interests in the Mortgagor or principals of the Mortgagor; or

(ii)         provides that such Mortgage Loan and any related Companion Loan may not be assumed without the consent of the mortgagee in connection with any such sale or other transfer,

then, for so long as such Mortgage Loan or related Serviced Companion Loan is being serviced under this Agreement, the Special Servicer, on behalf of the Trustee as the mortgagee of record, shall (a) exercise any right it may have with respect to such Mortgage Loan or related Companion Loan (x) to accelerate the payments thereon or (y) to withhold its consent to any sale or transfer, consistent with the Servicing Standard or (b) waive any right to exercise such rights, provided that, with respect to all Specially Serviced Loans and Non-Specially Serviced Loans, the Special Servicer has obtained, prior to the occurrence and continuance of a Control Termination Event and other than with respect to an Excluded Loan as to such party, the prior written consent (or deemed consent) of the Directing Holder (or (i) after the occurrence and during the continuance of a Control Termination Event, but prior to a Consultation Termination Event and (ii) other than with respect to any Excluded Loan as to such party, upon consultation with the Directing Holder and the Risk Retention Consultation Party pursuant to Section 6.08(a) hereof), which consent, if required, shall be deemed given ten (10) Business Days after receipt (unless earlier objected to by the Directing Holder) of the Special Servicer’s written analysis and recommendation with respect to such waiver together with such other information in the Special Servicer’s possession that is reasonably requested by the Directing Holder, and (iii) with respect to any Mortgage Loan (w) with a Stated Principal Balance greater than $35,000,000, (x) with a Stated Principal Balance greater than or equal to 5% of the aggregated Stated Principal Balance of the Mortgage Loans then outstanding, (y) together with all other Mortgage Loans with which it is cross-collateralized or cross-defaulted or together with all other Mortgage Loans with the same Mortgagor (or an affiliate thereof), that is one of the ten largest Mortgage Loans outstanding (by Stated Principal Balance), or (z) that is the Yorkshire & Lexington Towers Whole Loan or The Standard Highline NYC Whole Loan, the Master Servicer or the Special Servicer, as the case may be, prior to consenting to any action, shall obtain, a Rating Agency Confirmation from each Rating Agency and a confirmation of any applicable rating agency that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings of any class of Serviced Companion Loan Securities (if any) (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant to Section 3.25), provided, however, that with respect to subclauses (x) and (y) of this subclause (iii), such Mortgage Loan shall also have a Stated Principal Balance of at least $10,000,000 for such Rating Agency Confirmation requirement to apply. Notwithstanding anything herein to the contrary, with respect to any Excluded Loan with respect to the Directing Holder or, if the Directing Holder is the Directing Certificateholder, the Holder of the majority of the Controlling Class (regardless of whether an Operating Advisor Consultation Event has occurred and is continuing), the Special Servicer shall consult with the Operating Advisor, on a non-binding basis, in connection with the related transactions involving proposed Major Decisions that it is processing or for which its consent is required and consider alternative

 -254-

actions recommended by the Operating Advisor, in respect thereof, in accordance with the procedures set forth in Section 6.08 for consulting with the Operating Advisor.

If any Mortgage Loan (other than a Non-Serviced Mortgage Loan) or related Serviced Companion Loan provides that such Mortgage Loan or related Serviced Companion Loan may be assumed or transferred without the consent of the mortgagee provided that certain conditions are satisfied, then for so long as such Mortgage Loan or related Serviced Companion Loan is being serviced under this Agreement, the Special Servicer, with respect to all Specially Serviced Loans (other than a Non-Serviced Mortgage Loan) or related Serviced Companion Loans, on behalf of the Trustee as the mortgagee of record, shall determine in accordance with the Servicing Standard whether such conditions have been satisfied or, with respect to any Mortgage Loan which does not allow the mortgagee discretion in approving a transfer or assumption or does not allow for discretion in determining whether conditions to a transfer or assumption have been satisfied, the Master Servicer, on behalf of the Trustee as mortgagee of record, shall make such determination with respect to whether such conditions have been satisfied.

(b)         As to each Mortgage Loan (other than a Non-Serviced Mortgage Loan) and any related Serviced Companion Loan that contains a provision in the nature of a “due-on-encumbrance” clause that by its terms:

(i)          provides that such Mortgage Loan and any related Companion Loan shall (or may at the mortgagee’s option) become due and payable upon the creation of any additional lien or other encumbrance on the related Mortgaged Property or equity interests in the Mortgagor or principals of the Mortgagor; or

(ii)         requires the consent of the mortgagee to the creation of any such additional lien or other encumbrance on the related Mortgaged Property or equity interests in the Mortgagor or principals of the Mortgagor;

then, for so long as such Mortgage Loan (and related Companion Loan, if applicable) is serviced under this Agreement, the Special Servicer, on behalf of the Trustee as the mortgagee of record, shall (a) exercise any right it may have with respect to such Mortgage Loan or related Companion Loan (x) to accelerate the payments thereon or (y) to withhold its consent to the creation of any additional lien or other encumbrance, consistent with the Servicing Standard or (b) waive its right to exercise such rights, provided that with respect to all Specially Serviced Loans and Non-Specially Serviced Loans, prior to the occurrence and continuance of a Control Termination Event and other than with respect to an Excluded Loan as to such party, the Special Servicer has obtained the consent of the Directing Holder (or (i) after the occurrence and during the continuance of a Control Termination Event, but prior to a Consultation Termination

 -255-

Event and (ii) other than with respect to any Excluded Loan as to such party, upon consultation with the Directing Holder and the Risk Retention Consultation Party pursuant to Section 6.08(a) hereof), which consent, if required, shall be deemed given ten (10) Business Days after receipt by the Directing Holder of the Special Servicer’s written analysis and recommendation with respect to such waiver or exercise of such rights together with such other information in the Special Servicer’s possession that is reasonably requested by the Directing Holder, and the Special Servicer has obtained Rating Agency Confirmation from each Rating Agency and a confirmation of any applicable rating agency that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings of any class of Serviced Companion Loan Securities (if any) (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant to Section 3.25) if such Mortgage Loan (A) has an outstanding principal balance that is greater than or equal to 2% of the Stated Principal Balance of the outstanding Mortgage Loans, (B) has an LTV Ratio greater than 85% (including any existing and proposed debt), (C) has a Debt Service Coverage Ratio less than 1.20x (in each case, determined based upon the aggregate of the Stated Principal Balance of the Mortgage Loan and related Companion Loan, if any, and the principal amount of the proposed additional lien), (D) is the Yorkshire & Lexington Towers Whole Loan or The Standard Highline NYC Whole Loan, (E) is one of the ten largest Mortgage Loans (by Stated Principal Balance) or (F) has a Stated Principal Balance greater than $20,000,000; provided, however, that with respect to subclauses (A), (B), (C) and (E) of this subclause (iii), such Mortgage Loan shall also have a Stated Principal Balance of at least $10,000,000 for such Rating Agency Confirmation requirement to apply. Notwithstanding anything herein to the contrary, with respect to any Excluded Loan (regardless of whether an Operating Advisor Consultation Event has occurred and is continuing), the Special Servicer shall consult with the Operating Advisor, on a non-binding basis, in connection with the related transactions involving proposed Major Decisions and consider alternative actions recommended by the Operating Advisor, in respect thereof, in accordance with the procedures set forth in Section 6.08 for consulting with the Operating Advisor.

In connection with any request for a Rating Agency Confirmation from a Rating Agency (or, with respect to any Serviced Companion Loan Securities, the related rating agencies) pursuant to this Section 3.08(b), the Special Servicer shall (if not already provided in accordance with Section 3.25 of this Agreement) deliver a Review Package to the 17g-5 Information Provider (or, with respect to any Serviced Companion Loan Securities, the related 17g-5 information provider) in accordance with Section 3.25 of this Agreement.

To the extent permitted by the related Mortgage Loan documents, the Rating Agency Confirmation described in the immediately preceding paragraph or in Section 3.08(a) shall be an expense of the related Mortgagor; provided that if the Mortgage Loan documents are silent as to who bears the costs of obtaining any such Rating Agency Confirmation, the Special Servicer shall use reasonable efforts to make the related Mortgagor bear such costs and expenses. Unless determined to be a Nonrecoverable Advance such costs not collected from the related Mortgagor shall be advanced as a Servicing Advance.

If any Mortgage Loan or related Companion Loan provides that such Mortgage Loan or related Companion Loan may be further encumbered without the consent of the mortgagee provided that certain conditions are satisfied and there is no lender discretion with

 -256-

respect to the satisfaction of such conditions, then for so long as such Mortgage Loan or related Companion Loan is being serviced under this Agreement, the Special Servicer, with respect to all Specially Serviced Loans (other than a Non-Serviced Mortgage Loan) or related Serviced Companion Loans, on behalf of the Trustee as the mortgagee of record, shall determine in accordance with the Servicing Standard whether such conditions have been satisfied or, with respect to any Mortgage Loan which does not allow the mortgagee discretion in approving a further encumbrance or does not allow for discretion in determining whether conditions to a further encumbrance have been satisfied, the Master Servicer, on behalf of the Trustee as mortgagee of record, shall make such determination with respect to whether such conditions have been satisfied.

(c)         Nothing in this Section 3.08 shall constitute a waiver of the Trustee’s right, as the mortgagee of record, to receive notice of any assumption of a Mortgage Loan, any sale or other transfer of the related Mortgaged Property or the creation of any additional lien or other encumbrance with respect to such Mortgaged Property.

(d)         Except as otherwise permitted by Section 3.08(a) and (b) and/or Section 3.18, neither the Master Servicer nor the Special Servicer shall agree to modify, waive or amend any term of any Mortgage Loan and related Serviced Companion Loan, as applicable, in connection with the taking of, or the failure to take, any action pursuant to this Section 3.08. The Master Servicer and the Special Servicer, as applicable, shall provide copies of any final waivers (except with respect to provision of any such waivers to the 17g-5 Information Provider, exclusive of any Privileged Information) it effects pursuant to Section 3.08(a) or (b) to each other and to the 17g-5 Information Provider with respect to each Mortgage Loan, and shall notify the Trustee, the Certificate Administrator, each other and, subject to the terms of this Agreement, the 17g-5 Information Provider (for posting to the 17g-5 Information Provider’s Website in accordance with Section 3.25) and, with respect to a Whole Loan, the related Serviced Companion Noteholder, of any assumption or substitution agreement executed pursuant to Section 3.08(a) or (b) and shall forward thereto a copy of such agreement.

(e)         Notwithstanding any other provision of this Agreement, the Special Servicer may not waive its rights or grant its consent under any “due-on-sale” or “due-on-encumbrance” clause relating to any Mortgage Loan (other than any Non-Serviced Mortgage Loan) and any related Serviced Companion Loan without (A) the consent of the Directing Holder (prior to the occurrence and continuance of a Control Termination Event), (B) after the occurrence and during the continuance of a Control Termination Event, but prior to the occurrence and continuance a Consultation Termination Event, consultation with the Directing Holder and (C) with respect to a Specially Serviced Loan, consultation with the Risk Retention Consultation Party pursuant to Section 6.08.

 -257-

(f)          Notwithstanding the foregoing provisions of this Section 3.08, if the Master Servicer (with respect to Non-Specially Serviced Loans) or the Special Servicer (with respect to Specially Serviced Loans) makes a determination under Sections 3.08(a) or 3.08(b) hereof that the applicable conditions in the related Mortgage Loan or Companion Loan documents, as applicable, with respect to assumptions or encumbrances permitted without the consent of the mortgagee have been satisfied, the applicable assumptions and transfers may be subject to an assumption or other fee, unless such fees are otherwise prohibited pursuant to the Mortgage Loan documents; provided that any such fee not provided for in the Mortgage Loan documents does not constitute a “significant” change in yield pursuant to Treasury Regulations Section 1.1001-3(e)(2).

(g)         Notwithstanding any other provision of this Section 3.08, without any other approval or consent, the Master Servicer (for Mortgage Loans and Serviced Whole Loans other than Specially Serviced Loans) may grant and process a Mortgagor’s request for (i) consent to subject the related Mortgaged Property to an immaterial easement, a right of way or similar agreement for utilities, access, parking, public improvements or another purpose, (ii) consent to subordination of the related Mortgage Loan or Serviced Whole Loan to such easement, right of way or similar agreement and (iii) consent to any other matter that is not a Major Decision; provided that the Master Servicer (a) shall have determined in accordance with the Servicing Standard that such easement, right of way or similar agreement or other matter will not materially and adversely affect the operation or value of such Mortgaged Property or the Trust Fund’s interest in the Mortgaged Property and (b) shall have determined that such easement, right of way or similar agreement or other matter will not cause any Trust REMIC to fail to qualify as a REMIC at any time that any Certificates are outstanding. The Master Servicer may rely on an Opinion of Counsel in making any such determination under clause (b) above.

Section 3.09     Realization Upon Defaulted Loans and Companion Loans.   (a) Upon an event of default under the Mortgage Loan documents related to a Serviced Whole Loan or a Mortgage Loan with mezzanine debt, the Master Servicer shall promptly provide written notice to the related Companion Holder or mezzanine lender, as applicable, with a copy of such notice to the Special Servicer. The Special Servicer shall, subject to subsections (b) through (d) of this Section 3.09 and Section 3.24, subject to the Directing Holder’s and the Risk Retention Consultation Party’s respective rights pursuant to Section 6.08, and any Companion Holder or mezzanine lender’s rights under the related Intercreditor Agreement (in the case of a Serviced Whole Loan, on behalf of the holders of the beneficial interest of the related Companion Loan) or this Agreement, exercise reasonable efforts, consistent with the Servicing Standard, to foreclose upon or otherwise comparably convert (which may include an REO Acquisition) the ownership of property securing any such Mortgage Loan (other than any Non-Serviced Mortgage Loan) and related Companion Loan, if any, as come into and continue in default as to which no satisfactory arrangements (including by way of a discounted pay-off) can be made for collection of delinquent payments, and which are not released from the Trust Fund pursuant to any other provision hereof. The foregoing is subject to the provision that, in any case in which a Mortgaged Property shall have suffered damage from an Uninsured Cause, the Master Servicer or the Special Servicer shall not be required to make a Servicing Advance and expend funds toward the restoration of such property unless the Special Servicer has determined in its reasonable discretion that such restoration will increase the net proceeds of liquidation of such Mortgaged Property to Certificateholders after reimbursement to the Master Servicer for such

 -258-

Servicing Advance, and the Master Servicer or the Special Servicer has not determined that such Servicing Advance together with accrued and unpaid interest thereon would constitute a Nonrecoverable Advance. The costs and expenses incurred by the Special Servicer in any such proceedings shall be advanced by the Master Servicer; provided that, in each case, such cost or expense would not, if incurred, constitute a Nonrecoverable Servicing Advance. Nothing contained in this Section 3.09 shall be construed so as to require the Master Servicer or the Special Servicer, on behalf of the Trust, to make an offer on any Mortgaged Property at a foreclosure sale or similar proceeding that is in excess of the fair market value of such property, as determined by the Master Servicer or the Special Servicer in its reasonable judgment taking into account the factors described in Section 3.16(b) and the results of any Appraisal obtained pursuant to the following sentence, all such offers to be made in a manner consistent with the Servicing Standard. If and when the Special Servicer or the Master Servicer deems it necessary and prudent for purposes of establishing the fair market value of any Mortgaged Property securing a Defaulted Loan or any related defaulted Companion Loan, whether for purposes of making an offer at foreclosure or otherwise, the Special Servicer or the Master Servicer, as the case may be, is authorized to have an Appraisal performed with respect to such property by an Independent MAI-designated appraiser the cost of which shall be paid by the Master Servicer as a Servicing Advance.

(b)         The Special Servicer shall not acquire any personal property pursuant to this Section 3.09 unless either:

(i)          such personal property is incident to real property (within the meaning of Section 856(e)(1) of the Code) so acquired by the Special Servicer; or

(ii)         the Special Servicer shall have obtained an Opinion of Counsel (the cost of which shall be paid by the Master Servicer as a Servicing Advance) to the effect that the holding of such personal property by the Trust (to the extent not allocable to the related Companion Loan) will not cause an Adverse REMIC Event.

(c)         Notwithstanding the foregoing provisions of this Section 3.09 and Section 3.24, neither the Master Servicer nor the Special Servicer shall, on behalf of the Trustee, obtain title to a Mortgaged Property in lieu of foreclosure or otherwise, or take any other action with respect to any Mortgaged Property, if, as a result of any such action, the Trustee, on behalf of the Certificateholders, the Holders of any Loan-Specific Certificates and/or any related Companion Holder, would be considered to hold title to, to be a “mortgagee-in-possession” of, or to be an “owner” or “operator” of such Mortgaged Property within the meaning of CERCLA or any comparable law, unless (as evidenced by an Officer’s Certificate to such effect delivered to the Trustee) the Special Servicer has previously determined in accordance with the Servicing Standard, based on an Environmental Assessment of such Mortgaged Property performed by an Independent Person who regularly conducts Environmental Assessments and performed within six (6) months prior to any such acquisition of title or other action, that:

(i)          such Mortgaged Property is in compliance with applicable environmental laws or, if not, after consultation with an environmental consultant, that it would be in the best economic interest of the Certificateholders (and with respect to any Serviced Whole Loan, the related Companion Holders), as a collective whole as if such Certificateholders

 -259-

and, if applicable, such Companion Holders constituted a single lender, to take such actions as are necessary to bring such Mortgaged Property in compliance with such laws, and

(ii)         there are no circumstances present at such Mortgaged Property relating to the use, management or disposal of any hazardous materials for which investigation, testing, monitoring, containment, clean-up or remediation could be required under any currently effective federal, state or local law or regulation, or that, if any such hazardous materials are present for which such action could be required, after consultation with an environmental consultant, it would be in the best economic interest of the Certificateholders (and with respect to any Serviced Whole Loan, the Companion Holders), as a collective whole as if such Certificateholders and, if applicable, such Companion Holders constituted a single lender, to take such actions with respect to the affected Mortgaged Property.

The cost of any such Environmental Assessment shall be paid by the Master Servicer as a Servicing Advance and the cost of any remedial, corrective or other further action contemplated by clause (i) and/or clause (ii) of the preceding sentence shall be paid by the Master Servicer as a Servicing Advance, unless it is a Nonrecoverable Servicing Advance (in which case it shall be an expense of the Trust and, in the case of a Serviced Whole Loan, shall be withdrawn in accordance with the related Intercreditor Agreement by the Master Servicer from the Collection Account, including from the Companion Distribution Account (such withdrawal to be made from amounts on deposit therein that are otherwise payable on or allocable to such Serviced Whole Loan)); and if any such Environmental Assessment so warrants, the Special Servicer shall, except with respect to any Companion Loan and any Environmental Assessment ordered after such Mortgage Loan has been paid in full, perform such additional environmental testing at the expense of the Trust as it deems necessary and prudent to determine whether the conditions described in clauses (i) and (ii) of the preceding sentence have been satisfied. With respect to Non-Specially Serviced Loans, the Master Servicer and, with respect to Specially Serviced Loans, the Special Servicer (other than any Non-Serviced Mortgage Loan) shall review and be familiar with the terms and conditions relating to enforcing claims and shall monitor the dates by which any claim or action must be taken (including delivering any notices to the insurer and using reasonable efforts to perform any actions required under such policy) under each environmental insurance policy in effect and obtained on behalf of the mortgagee to receive the maximum proceeds available under such policy for the benefit of the Certificateholders and the Trustee (as holder of the Lower-Tier Regular Interests).

(d)         If (i) the environmental testing contemplated by subsection (c) above establishes that either of the conditions set forth in clauses (i) and (ii) of subsection (c) above of the first sentence thereof has not been satisfied with respect to any Mortgaged Property securing a Defaulted Loan and, in the case of a Serviced Mortgage Loan, any related Companion Loan, and (ii) there has been no breach of any of the representations and warranties set forth in or required to be made pursuant to Section 6 of each of the Mortgage Loan Purchase Agreements for which the applicable Mortgage Loan Seller could be required to repurchase such Defaulted Loan pursuant to Section 6 of the applicable Mortgage Loan Purchase Agreement, then the Special Servicer shall take such action as it deems to be in the best economic interest of the Trust (other than proceeding to acquire title to the Mortgaged Property) and is hereby authorized, with

the consent of the Directing Holder and after consultation with the Risk Retention Consultation Party pursuant to Section 6.08(a) (in each case, (A) prior to the occurrence and continuance of a Control Termination Event (or with respect to any AB Mortgage Loan, after the occurrence and during the continuation of an AB Control Appraisal Period, but prior to the occurrence and continuance of a Control Termination Event) and (B) other than with respect to any Excluded Loan as to such party) at such time as it deems appropriate to release such Mortgaged Property from the lien of the related Mortgage, provided that, if such Mortgage Loan has a then-outstanding principal balance of greater than $1,000,000, then prior to the release of the related Mortgaged Property from the lien of the related Mortgage, (i) the Special Servicer shall have notified the Rating Agencies, the Trustee, the Certificate Administrator, the Master Servicer, the Directing Holder and the Risk Retention Consultation Party (in the case of the Directing Holder, prior to the occurrence and continuance of a Consultation Termination Event, and in the case of the Directing Holder or the Risk Retention Consultation Party other than with respect to any Excluded Loan as to such party), in writing of its intention to so release such Mortgaged Property and the bases for such intention, (ii) the Certificate Administrator shall have posted such notice of the Special Servicer’s intention to so release such Mortgaged Property to the Certificate Administrator’s Website pursuant to Section 3.13(b) and (iii) in addition to the prior written consent of the Directing Holder as required above, the Holders of Certificates entitled to a majority of the Voting Rights shall have consented or have been deemed to have consented to such release within thirty (30) days of the Certificate Administrator’s posting such notice to the Certificate Administrator’s Website (failure to respond by the end of such 30-day period being deemed consent of the Holders of the Certificates). To the extent any fee charged by any Rating Agency in connection with rendering such written confirmation is not paid by the related Mortgagor, such fee is to be an expense of the Trust; provided that the Special Servicer shall use commercially reasonable efforts to collect such fee from the Mortgagor to the extent permitted under the related Mortgage Loan documents.

(e)         The Special Servicer shall provide written reports and a copy of any Environmental Assessments in electronic format to the Directing Holder and the Risk Retention Consultation Party (in each case, other than with respect to any Excluded Loan as to such party), the Master Servicer and the 17g-5 Information Provider monthly regarding any actions taken by the Special Servicer with respect to any Mortgaged Property securing a Defaulted Loan, or defaulted Companion Loan as to which the environmental testing contemplated in subsection (c) above has revealed that either of the conditions set forth in clauses (i) and (ii) of the first sentence thereof has not been satisfied, in each case until the earlier to occur of satisfaction of both such conditions, repurchase of the related Mortgage Loan or Trust Subordinate Companion Loan by the applicable Mortgage Loan Seller or release of the lien of the related Mortgage on such Mortgaged Property.

(f)          The Special Servicer shall notify the Master Servicer of any abandoned and/or foreclosed properties which require reporting to the Internal Revenue Service and shall provide the Master Servicer with all information regarding forgiveness of indebtedness and required to be reported with respect to any Mortgage Loan or related Companion Loan that is abandoned or foreclosed and the Master Servicer shall report to the Internal Revenue Service and the related Mortgagor, in the manner required by applicable law, such information and the Master Servicer shall report, via Form 1099A or Form 1099C (or any successor form), all forgiveness of indebtedness and abandonment and foreclosure to the extent such information has

 -261-

been provided to the Master Servicer by the Special Servicer. Upon request, the Master Servicer shall deliver a copy of any such report to the Trustee and the Certificate Administrator.

(g)         The Special Servicer shall have the right to determine, in accordance with the Servicing Standard, the advisability of the maintenance of an action to obtain a deficiency judgment if the state in which the Mortgaged Property is located and the terms of the Mortgage Loan (and if applicable, the related Companion Loan) permit such an action.

(h)         The Special Servicer shall maintain accurate records, prepared by one of its Servicing Officers, of each Final Recovery Determination in respect of a Defaulted Loan (other than with respect to a Non-Serviced Mortgage Loan) or defaulted Companion Loan or any REO Property (other than any Non-Serviced Mortgaged Property) and the basis thereof. Each Final Recovery Determination shall be evidenced by an Officer’s Certificate promptly delivered to the Trustee, the Certificate Administrator, the Directing Holder and the Risk Retention Consultation Party (but in the case of the Directing Holder and the Risk Retention Consultation Party, other than with respect to any Excluded Loan as to such party) and the Master Servicer and in no event later than the next succeeding P&I Advance Determination Date.

Section 3.10     Trustee and Custodian to Cooperate; Release of Mortgage Files.  (a) Upon the payment in full of any Mortgage Loan or Trust Subordinate Companion Loan (other than a Non-Serviced Mortgage Loan), or the receipt by the Master Servicer or the Special Servicer, as the case may be, of a notification that payment in full shall be escrowed in a manner customary for such purposes, the Master Servicer or the Special Servicer, as the case may be, will promptly notify the Trustee and the Custodian and request delivery of the related Mortgage File. Any such notice and request shall be in the form of a Request for Release signed by a Servicing Officer and shall include a statement to the effect that all amounts received or to be received in connection with such payment which are required to be deposited in the Collection Account pursuant to Section 3.04(a) or remitted to the Master Servicer to enable such deposit, have been or will be so deposited. Within three (3) Business Days (or within such shorter period as release can reasonably be accomplished if the Master Servicer or the Special Servicer notifies the Custodian of an exigency) of receipt of such notice and request, the Custodian shall release the related Mortgage File to the Master Servicer or the Special Servicer, as the case may be; provided that in the case of the payment in full of a Serviced Companion Loan or its related Mortgage Loan, the related Mortgage File shall not be released by the Custodian unless the related Serviced Whole Loan is paid in full. No expenses incurred in connection with any instrument of satisfaction or deed of reconveyance shall be chargeable to the Collection Account.

(b)         From time to time as is appropriate for servicing or foreclosure of any Mortgage Loan (other than any Non-Serviced Mortgage Loan) (and any related Companion Loan), the Master Servicer or the Special Servicer shall deliver to the Custodian a Request for Release signed by a Servicing Officer. Upon receipt of the foregoing, the Custodian shall deliver the Mortgage File or any document therein to the Master Servicer or the Special Servicer (or a designee), as the case may be. Upon return of such Mortgage File or such document to the Custodian, or the delivery to the Trustee and the Custodian of a certificate of a Servicing Officer of the Master Servicer or the Special Servicer, as the case may be, stating that such Mortgage Loan (and, in the case of a Serviced Whole Loan, the related Companion Loan), was liquidated and that all amounts received or to be received in connection with such liquidation which are

 -262-

required to be deposited into the Collection Account (including amounts related to the related Companion Loan, if applicable) pursuant to Section 3.04(a) have been or will be so deposited, or that such Mortgage Loan has become an REO Property, a copy of the Request for Release shall be released by the Custodian to the Master Servicer or the Special Servicer (or a designee), as the case may be, with the original being released upon termination of the Trust.

(c)         Within three (3) Business Days (or within such shorter period as delivery can reasonably be accomplished if the Special Servicer notifies the Trustee of an exigency) of receipt thereof, the Trustee shall execute and deliver to the Special Servicer any court pleadings, requests for trustee’s sale or other documents necessary to the foreclosure or trustee’s sale in respect of a Mortgaged Property or to any legal action brought to obtain judgment against any Mortgagor on the Mortgage Note (including any note evidencing a related Companion Loan) or Mortgage or to obtain a deficiency judgment, or to enforce any other remedies or rights provided by the Mortgage Note or Mortgage or otherwise available at law or in equity. The Special Servicer shall be responsible for the preparation of all such documents and pleadings. When submitted to the Trustee for signature, such documents or pleadings shall be accompanied by a certificate of a Servicing Officer requesting that such pleadings or documents be executed by the Trustee and certifying as to the reason such documents or pleadings are required and that the execution and delivery thereof by the Trustee will not invalidate or otherwise affect the lien of the Mortgage, except for the termination of such a lien upon completion of the foreclosure or trustee’s sale. The Trustee shall not be required to review such documents for their sufficiency or enforceability.

With respect to each Servicing Shift Whole Loan, on and after the related Servicing Shift Securitization Date, if pursuant to the related Co-Lender Agreement and the related Non-Serviced PSA, and as appropriate for enforcing the terms of such Servicing Shift Whole Loan, as applicable, the related Non-Serviced Master Servicer submits in a Request for Release delivery to it of the original Note, then the Custodian shall release or cause the release of such original Note to the related Non-Serviced Master Servicer or its designee.

(d)         If, from time to time, pursuant to the terms of the applicable Non-Serviced Intercreditor Agreement and the applicable Non-Serviced PSA, and as appropriate for enforcing the terms of a Non-Serviced Mortgage Loan, the applicable Non-Serviced Master Servicer requests delivery to it of the original Mortgage Note for a Non-Serviced Mortgage Loan, then the Custodian shall release or cause the release of such original Mortgage Note to such Non-Serviced Master Servicer or its designee.

Section 3.11     Servicing Compensation.  (a) As compensation for its activities hereunder, the Master Servicer shall be entitled to receive the Servicing Fee with respect to each Mortgage Loan, Serviced Companion Loan and REO Loan (other than the portion of any REO Loan related to any Non-Serviced Companion Loan) (including Specially Serviced Loans and any Non-Serviced Mortgage Loan constituting a “specially serviced loan” under any related Non-Serviced PSA). As to each Mortgage Loan, Companion Loan and REO Loan, the Servicing Fee shall accrue from time to time at the Servicing Fee Rate and shall be computed on the basis of the Stated Principal Balance of such Mortgage Loan, Companion Loan or REO Loan, as the case may be, and in the same manner as interest is calculated on such Mortgage Loan, Companion Loan or REO Loan, as the case may be, and, in connection with any partial month

 -263-

interest payment, for the same period respecting which any related interest payment due on such Mortgage Loan or Companion Loan or deemed to be due on such REO Loan is computed. The Servicing Fee with respect to any Mortgage Loan, Companion Loan or REO Loan shall cease to accrue if a Liquidation Event occurs with respect to the related Mortgage Loan, except that if such Mortgage Loan is part of a Serviced Whole Loan and such Serviced Whole Loan continues to be serviced and administered under this Agreement notwithstanding such Liquidation Event, then the applicable Servicing Fee shall continue to accrue and be payable as if such Liquidation Event did not occur. The Servicing Fee shall be payable monthly, on a loan-by-loan basis, from payments of interest on each Mortgage Loan, Companion Loan and REO Revenues allocable as interest on each REO Loan, and as otherwise provided by Section 3.05(a). The Master Servicer shall be entitled to recover unpaid Servicing Fees in respect of any Mortgage Loan, Companion Loan or REO Loan out of that portion of related payments, Insurance and Condemnation Proceeds, Liquidation Proceeds and REO Revenues (in the case of an REO Loan) allocable as recoveries of interest, to the extent permitted by Section 3.05(a). Except as set forth in the next two sentences, the third paragraph of this Section 3.11(a), Section 6.03, Section 6.05 and Section 7.01(c), the right to receive the Servicing Fee may not be transferred in whole or in part (except in connection with a transfer of all of the Master Servicer’s duties and obligations hereunder to a successor servicer in accordance with the terms hereof). With respect to each Serviced Pari Passu Companion Loan, the Servicing Fee shall be payable to the Master Servicer from amounts payable in respect of such Serviced Pari Passu Companion Loan, subject to the terms of the related Intercreditor Agreement.

The Master Servicer shall be entitled to retain, and shall not be required to deposit in the Collection Account pursuant to Section 3.04(a), additional servicing compensation (other than with respect to a Non-Serviced Mortgage Loan) in the form of the following amounts to the extent collected from the related Mortgagor: (i) 100% of Excess Modification Fees related to any modifications, waivers, extensions or amendments of any Non-Specially Serviced Loans (including any related Serviced Companion Loans, to the extent not prohibited by the related Intercreditor Agreement and that do not involve a Major Decision and 50% of Excess Modification Fees related to any modifications, waivers, extensions or amendments of any Mortgage Loans (other than any Non-Serviced Mortgage Loan) and any related Serviced Companion Loans that are not Specially Serviced Loans to the extent not prohibited by the related Intercreditor Agreement and that involve one or more Major Decisions (whether or not processed by the Special Servicer), (ii) 100% of all assumption application fees received on any Mortgage Loans, only for which the Master Servicer is processing the underlying assumption related transaction (including any related Serviced Companion Loan, to the extent not prohibited by the related Intercreditor Agreement) (whether or not the consent of the Special Servicer is required) and 100% of all defeasance fees (provided that any such defeasance fee will not include any Modification Fees or waiver fees in connection with a transaction for which the consent or approval of the Special Servicer is required (and specifically excluding any defeasance fees)); (iii) 100% of assumption, waiver, processing, consent and earnout fees, and other similar fees pursuant to Section 3.08 and Section 3.18 or other actions performed in connection with this Agreement on the Non-Specially Serviced Loans (including any related Serviced Companion Loan, to the extent not prohibited by the related Intercreditor Agreement), which do not involve a Major Decision; (iv) 50% of all assumption, waiver, processing, consent and earnout fees, and other similar fees (other than assumption application and defeasance fees), pursuant to Section 3.08 and Section 3.18 on any Non-Specially Serviced Loan (including any

 -264-

related Serviced Companion Loan, to the extent not prohibited by the related Intercreditor Agreement) which involve a Major Decision (whether or not processed by the Special Servicer) and only to the extent that all amounts then due and payable with respect to the related Mortgage Loan or any related Serviced Companion Loan have been paid; (v) 100% of charges by the Master Servicer collected for checks returned for insufficient funds and charges for beneficiary statements or demands actually paid by the related Mortgagors relating to the accounts held by the Master Servicer; and (vi) late payment charges and default interest paid by the Mortgagors (that accrued while the related Mortgage Loans (other than any Non-Serviced Mortgage Loan) or any related Serviced Companion Loan (to the extent not prohibited by the related Intercreditor Agreement) were not Specially Serviced Loans), but only to the extent such late payment charges and default interest are not needed to pay interest on Advances or certain additional trust fund expenses incurred with respect to the related Mortgage Loan or, if provided under the related Intercreditor Agreement, any related Serviced Companion Loan since the Closing Date. Subject to Section 3.11(d), the Master Servicer shall also be entitled to additional servicing compensation in the form of: (i) Penalty Charges to the extent provided in Section 3.11(d), (ii) interest or other income earned on deposits relating to the Trust Fund in the Collection Account or the Companion Distribution Account in accordance with Section 3.06(b) (but only to the extent of the Net Investment Earnings, if any, with respect to such account for the period from and including the prior Distribution Date to and including the P&I Advance Date related to the current Distribution Date), (iii) interest or other income earned on deposits in the Servicing Account which are not required by applicable law or the related Mortgage Loan or Trust Subordinate Companion Loan to be paid to the Mortgagor and (iv) the difference, if positive, between Prepayment Interest Excess and Prepayment Interest Shortfalls collected on the Mortgage Loans, the Trust Subordinate Companion Loans and any Serviced Pari Passu Companion Loan, during the related Collection Period to the extent not required to be paid as Compensating Interest Payments. The Master Servicer shall be required to pay out of its own funds all expenses incurred by it in connection with its servicing activities hereunder (including, without limitation, payment of any amounts due and owing to any of its Sub-Servicers and the premiums for any blanket Insurance Policy insuring against hazard losses pursuant to Section 3.07), if and to the extent such expenses are not payable directly out of the Collection Account and the Master Servicer shall not be entitled to reimbursement therefor except as expressly provided in this Agreement.

With respect to any of the preceding fees as to which both the Master Servicer and the Special Servicer are entitled to receive a portion thereof, the Master Servicer and the Special Servicer shall each have the right in their sole discretion, but not any obligation, to reduce or elect not to charge its respective portion of such fee; provided that without the consent of the affected party (A) neither the Master Servicer nor the Special Servicer shall have the right to reduce or elect not to charge the portion of any such fee due to the other and (B) to the extent either the Master Servicer or the Special Servicer exercises its right to reduce or elect not to charge its respective portion in any such fee, the party that reduced or elected not to charge its respective portion of such fee shall not have any right to share in any part of the other party’s portion of such fee. If the Master Servicer decides not to charge any fee, the Special Servicer shall nevertheless be entitled to charge its portion of the related fee to which the Special Servicer would have been entitled if the Master Servicer had charged a fee and the Master Servicer shall not be entitled to any of such fee charged by the Special Servicer.

 -265-

Notwithstanding anything herein to the contrary, the Master Servicer and the Special Servicer shall each be entitled to charge and retain reasonable review fees in connection with any Mortgagor request to the extent such fees are not prohibited under the related Mortgage Loan documents and are actually paid by or on behalf of the related Mortgagor. Notwithstanding anything herein to the contrary, KeyBank National Association may, at its option, assign or pledge to any third party or retain for itself the Transferable Servicing Interest; provided, however, that in the event of any resignation or termination of such Master Servicer, all or any portion of the Transferable Servicing Interest may be reduced by the Trustee to the extent reasonably necessary (in the sole discretion of the Trustee) for the Trustee to obtain a qualified successor master servicer that meets the requirements of Section 6.05 and who requires market-rate servicing compensation that accrues at a per annum rate in excess of the Retained Fee Rate, and any such assignment of the Transferable Servicing Interest shall, by its terms be expressly subject to the terms of this Agreement and such reduction. The Master Servicer shall pay the Transferable Servicing Interest to the holder of the Transferable Servicing Interest at such time and to the extent the Master Servicer is entitled to receive payment of its Servicing Fees hereunder, notwithstanding any resignation or termination of KeyBank National Association hereunder (subject to reduction pursuant to the preceding sentence).

(b)         As compensation for its activities hereunder, the Special Servicer shall be entitled to receive the Special Servicing Fee with respect to each Specially Serviced Loan and REO Loan (other than a Non-Serviced Mortgage Loan and any REO Loan relating to a Non-Serviced Mortgaged Property). As to each Specially Serviced Loan and REO Loan, the Special Servicing Fee shall accrue from time to time at the Special Servicing Fee Rate and shall be computed on the basis of the Stated Principal Balance of such Specially Serviced Loan or REO Loan, as the case may be, and in the same manner as interest is calculated on the Specially Serviced Loans or REO Loans, as the case may be, and, in connection with any partial month interest payment, for the same period respecting which any related interest payment due on such Specially Serviced Loan or deemed to be due on such REO Loan is computed. The Special Servicing Fee with respect to any Specially Serviced Loan or REO Loan shall cease to accrue if a Liquidation Event occurs with respect to the related Mortgage Loan or Trust Subordinate Companion Loan. The Special Servicing Fee shall be payable monthly, on a loan-by-loan basis, in accordance with the provisions of Section 3.05(a). The right to receive the Special Servicing Fee may not be transferred in whole or in part except in connection with the transfer of all of the Special Servicer’s responsibilities and obligations under this Agreement. The Special Servicer shall not be entitled to any Special Servicing Fees with respect to a Non-Serviced Mortgage Loan.

(c)         Additional servicing compensation in the form of (i) 100% of all Excess Modification Fees related to modifications, waivers, extensions or amendments of any Specially Serviced Loans, (ii) 100% of all assumption application fees received on any Mortgage Loans and any related Serviced Companion Loan (to the extent not prohibited by the related Intercreditor Agreement) only for which the Special Servicer is processing the underlying assumption related transaction, (iii) 100% of all assumption fees and other related fees received with respect to the Specially Serviced Loans, (iv) 100% of waiver, consent and earnout fees and similar fees, pursuant to Section 3.08 and Section 3.18 or other actions performed in connection with this Agreement on the Specially Serviced Loans or certain other similar fees paid by the related Mortgagor, (v) 50% of all Excess Modification Fees and assumption fees, waiver fees,

 -266-

consent fees, earnout fees, and similar fees pursuant to Section 3.08 or Section 3.18 received with respect to all Non-Specially Serviced Loans (including any related Serviced Companion Loan, to the extent not prohibited by the related Intercreditor Agreement) (excluding any Non-Serviced Mortgage Loan) that involve one or more Major Decisions, and (vi) 100% of charges by the Special Servicer for checks returned for insufficient funds, charges for beneficiary statements or demands, in each case, relating to the accounts held by the Special Servicer, shall be promptly paid to the Special Servicer by the Master Servicer (or directly from the related Mortgagor) to the extent such fees are paid by the Mortgagor and shall not be required to be deposited in the Collection Account pursuant to Section 3.04(a). Subject to Section 3.11(d), the Special Servicer shall also be entitled to additional servicing compensation in the form of: (i) Penalty Charges to the extent provided in Section 3.11(d) and (ii) interest or other income earned on deposits relating to the Trust Fund in the REO Account and Loss of Value Reserve Fund in accordance with Section 3.06(b) (but only to the extent of the Net Investment Earnings, if any, with respect to such account for the period from and including the prior Distribution Date to and including the P&I Advance Date related to such Distribution Date). In addition, the Special Servicer shall also be entitled to retain as additional servicing compensation (other than with respect to any Non-Serviced Mortgage Loan) reasonable review fees in connection with any Mortgagor request to the extent such review fees are not prohibited under the related Mortgage Loan documents, and only to the extent actually paid by the related Mortgagor. The Special Servicer shall also be entitled to additional servicing compensation in the form of a Workout Fee with respect to each Corrected Loan at the Workout Fee Rate on such Corrected Loan for so long as it remains a Corrected Loan; provided, however, that after receipt by the Special Servicer of Workout Fees with respect to such Corrected Loan in an amount equal to $25,000, any Workout Fees in excess of such amount shall be reduced by the Excess Modification Fee Amount; provided, further, however, that, other than with respect to the Yorkshire & Lexington Towers Whole Loan, in the event the Workout Fee collected over the course of such workout calculated at the Workout Fee Rate is less than $25,000, then the Special Servicer shall be entitled to an amount from the final payment on the related Corrected Loan (including any related Serviced Companion Loan) that would result in the total Workout Fees payable to the Special Servicer in respect of that Corrected Loan (including any related Serviced Companion Loan) to be $25,000. The Workout Fee shall be reduced (but not below zero) pursuant to the preceding sentence with respect to each collection on such Corrected Loan from which fee would otherwise be payable until an amount equal to such Excess Modification Fee Amount has been deducted in full. The Workout Fee with respect to any Corrected Loan will cease to be payable if such loan again becomes a Specially Serviced Loan; provided that a new Workout Fee will become payable if and when such Specially Serviced Loan again becomes a Corrected Loan. The Special Servicer shall not be entitled to any Workout Fee with respect to a Non-Serviced Mortgage Loan. If the Special Servicer is terminated (other than for cause) or resigns, it shall retain the right to receive any and all Workout Fees payable in respect of Mortgage Loans or any related Companion Loan that became Corrected Loans prior to the time of that termination or resignation except the Workout Fees will no longer be payable if the Corrected Loan subsequently becomes a Specially Serviced Loan. If the Special Servicer resigns or is terminated (other than for cause), it will receive any Workout Fees payable on Specially Serviced Loans for which the resigning or terminated Special Servicer had determined to grant a forbearance or cured the event of default through a modification, restructuring or workout negotiated by the Special Servicer and evidenced by a signed writing, but which had not as of the time the Special Servicer resigned or

 -267-

was terminated become a Corrected Loan solely because the Mortgagor had not had sufficient time to make three consecutive timely Periodic Payments and which subsequently becomes a Corrected Loan as a result of the Mortgagor making such three consecutive timely Periodic Payments except the Workout Fees will no longer be payable if the Corrected Loan subsequently becomes a Specially Serviced Loan. The successor special servicer shall not be entitled to any portion of such Workout Fees. The Special Servicer shall not be entitled to receive any Workout Fees after termination for cause. A Liquidation Fee will be payable with respect to each Specially Serviced Loan (other than a Non-Serviced Mortgage Loan) or REO Property (other than a Non-Serviced Mortgaged Property) as to which the Special Servicer receives any Liquidation Proceeds or Insurance and Condemnation Proceeds subject to the exceptions set forth in the definition of Liquidation Fee (such Liquidation Fee to be paid out of such Liquidation Proceeds, Insurance and Condemnation Proceeds). If, however, Liquidation Proceeds or Insurance and Condemnation Proceeds are received with respect to any Corrected Loan and the Special Servicer is properly entitled to a Workout Fee, such Workout Fee will be payable based on and out of the portion of such Liquidation Proceeds and Insurance and Condemnation Proceeds that constitute principal and/or interest on such Mortgage Loan. Notwithstanding anything herein to the contrary, the Special Servicer shall only be entitled to receive a Liquidation Fee or a Workout Fee, but not both, with respect to proceeds on any Mortgage Loan or Trust Subordinate Companion Loan. Notwithstanding the foregoing, with respect to any Companion Loan, the Liquidation Fee, Workout Fee and Special Servicing Fees, if any, will be computed as provided in the related Intercreditor Agreement or to the extent such Intercreditor Agreement is silent or refers to this Agreement or indicates such fees are paid in accordance with this Agreement, as provided herein as though such Companion Loan were a Mortgage Loan. Subject to Section 3.11(d), the Special Servicer will also be entitled to additional fees in the form of Penalty Charges. The Special Servicer shall be required to pay out of its own funds all expenses incurred by it in connection with its servicing activities hereunder (including, without limitation, payment of any amounts, other than management fees in respect of REO Properties, due and owing to any of its Sub-Servicers and the premiums for any blanket Insurance Policy obtained by it insuring against hazard losses pursuant to Section 3.07), if and to the extent such expenses are not expressly payable directly out of the Collection Account or the REO Account, and the Special Servicer shall not be entitled to reimbursement therefor except as expressly provided in this Agreement.

With respect to any of the preceding fees as to which both the Master Servicer and the Special Servicer are entitled to receive a portion thereof, the Master Servicer and the Special Servicer shall each have the right in their sole discretion, but not any obligation, to reduce or elect not to charge its respective portion of such fee; provided that (A) neither the Master Servicer nor the Special Servicer shall have the right to reduce or elect not to charge the portion of any such fee due to the other and (B) to the extent either the Master Servicer or the Special Servicer exercises its right to reduce or elect not to charge its respective portion in any such fee, the party that is reduced or elected not to charge its respective portion of such fee shall not have any right to share in any part of the other party’s portion of such fee. If the Master Servicer decides not to charge any fee, the Special Servicer shall nevertheless be entitled to charge its portion of the related fee to which the Special Servicer would have been entitled if the Master Servicer had charged a fee and the Master Servicer shall not be entitled to any of such fee charged by the Special Servicer.

 -268-

(d)         In determining the compensation of the Master Servicer or the Special Servicer, as applicable, with respect to Penalty Charges, on any Distribution Date, the aggregate Penalty Charges collected on any Mortgage Loan (other than a Non-Serviced Mortgage Loan) and any related Companion Loan since the prior Distribution Date shall be applied (in such order) to reimburse (i) the Master Servicer, the Special Servicer or the Trustee for interest on Advances on such Mortgage Loan or related Companion Loan, if applicable (and, in connection with a Non-Serviced Mortgage Loan, the applicable Non-Serviced Master Servicer, the applicable Non-Serviced Special Servicer or the applicable Non-Serviced Trustee for interest on the servicing advances made by any such party with respect to a Non-Serviced Whole Loan pursuant to the applicable Non-Serviced PSA, to the extent not prohibited by the applicable Non-Serviced Intercreditor Agreement) due on such Distribution Date, (ii) the Trust for all interest on Advances previously paid to the Master Servicer or the Trustee pursuant to Section 3.05(a)(vi) hereof (and, in connection with a Non-Serviced Mortgage Loan, the related trust for all interest on servicing advances reimbursed by such trust to any party under the applicable Non-Serviced PSA, which resulted in an additional expense for the Trust, to the extent not prohibited by the applicable Non-Serviced Intercreditor Agreement) with respect to such Mortgage Loan or related Companion Loan, if applicable and (iii) the Trust for all additional expenses of the Trust (other than Special Servicing Fees, Workout Fees and Liquidation Fees), including without limitation, inspections by the Special Servicer and all unpaid Advances incurred since the Closing Date with respect to such Mortgage Loan. Penalty Charges (other than with respect to a Non-Serviced Mortgage Loan, which shall be payable as additional servicing compensation under the related Non-Serviced PSA) remaining thereafter shall be distributed to the Master Servicer, if and to the extent accrued while such Mortgage Loan and any related Companion Loan was a Non-Specially Serviced Loan, and to the Special Servicer, if and to the extent accrued on such Mortgage Loan during the period such Mortgage Loan was a Specially Serviced Loan or REO Loan. Any Penalty Charges paid or payable as additional servicing compensation to the Master Servicer and the Special Servicer shall be distributed between the Master Servicer and the Special Servicer, on a pro rata basis, based on the Master Servicer’s and the Special Servicer’s respective entitlements to such compensation described in the previous sentence. If the Special Servicer has partially waived any Penalty Charge (part of which accrued prior to the related Servicing Transfer Event), any collections in respect of such Penalty Charge shall be shared by the Master Servicer only to the extent of the Penalty Charges accrued and not waived prior to the related Servicing Transfer Event. If the Master Servicer has partially waived any Penalty Charge, any collections in respect of such Penalty Charge shall be shared pro rata by the Master Servicer and the Special Servicer based on the respective portions of such Penalty Charge to which each would otherwise have been entitled. Notwithstanding the foregoing, Penalty Charges with respect to any Companion Loan will be allocated pursuant to the applicable Intercreditor Agreement after payment of all related Advances and interest thereon and additional expenses of the Trust in accordance with this Section 3.11(d).

If a Servicing Shift Whole Loan becomes a Specially Serviced Loan prior to the applicable Servicing Shift Securitization Date, the Special Servicer shall service and administer such Servicing Shift Whole Loan and any related REO Property in the same manner as any other Specially Serviced Loan or Serviced REO Property and shall be entitled to all rights and compensation earned with respect to such Serviced Whole Loan as Special Servicer of such Serviced Whole Loan. With respect to a Servicing Shift Mortgage Loan, prior to the applicable Servicing Shift Securitization Date, no other special servicer will be entitled to any such

 -269-

compensation or have such rights and obligations. If a Servicing Shift Whole Loan is still a Specially Serviced Loan on the applicable Servicing Shift Securitization Date, the Non-Serviced Special Servicer and the Special Servicer shall be entitled to compensation with respect to such Servicing Shift Whole Loan as if the Special Servicer were being terminated as the Special Servicer with respect to such Servicing Shift Whole Loan and the Non-Serviced Special Servicer were replacing the Special Servicer as the successor Special Servicer with respect to such Servicing Shift Whole Loan.

Not later than 5:00 p.m. (New York City time) on the Master Servicer Remittance Date beginning December 2017, the Master Servicer shall deliver to the Certificate Administrator the CREFC^® Schedule AL File in EDGAR-Compatible Format; provided that the Master Servicer shall have no obligation to prepare or deliver any such CREFC^® Schedule AL File unless the Depositor has delivered the items required by Section 2.01(i). If the CREFC^® Schedule AL File is not provided by 5:00 p.m. (New York City time) on the Master Servicer Remittance Date, the Certificate Administrator shall request such CREFC^® Schedule AL File from the Master Servicer via email at KC_Investor_Reporting@KeyBank.com, with a copy to the Depositor at chuck.lee@credit-suisse.com. In preparing the CREFC^® Schedule AL File and any Schedule AL Additional File for any given Distribution Date, and without any due diligence, investigation or verification, the Master Servicer shall be entitled to conclusively rely, absent manifest error, on the content, completeness, accuracy and compliance with any applicable requirements of Items 1111(h) and 1125 of Regulation AB and Item 601(b) of Regulation S-K under the Securities Act as in effect on the Closing Date of the Initial Schedule AL File, any Initial Schedule AL Additional File and Annex A-1 to the Prospectus. The Master Servicer may concurrently with the delivery of the related CREFC^® Schedule AL File, deliver any related Schedule AL Additional File in EDGAR-Compatible Format to the Certificate Administrator. The CREFC^® Schedule AL File and the Schedule AL Additional File shall each be a single file. Neither the Certificate Administrator nor the Master Servicer shall be required to combine multiple CREFC^® Schedule AL Files or Schedule AL Additional Files, unless, solely with respect to the Master Servicer, multiple Sub-Servicers prepare and submit such CREFC^® Schedule AL Files or Schedule AL Additional Files to the Master Servicer. The Certificate Administrator shall not be required to review, redact, reconcile, edit or verify the content, completeness or accuracy of the information contained in any CREFC^® Schedule AL File or any Schedule AL Additional File. The Certificate Administrator shall not be deemed to have actual knowledge of the contents of any CREFC^® Schedule AL File or Schedule AL Additional File solely by its receipt thereof.

In the absence of manifest error, the Master Servicer shall be entitled to conclusively rely upon, without investigation or inquiry, any information and reports delivered to it by any third party, and the Certificate Administrator shall be entitled to conclusively rely upon the Master Servicer’s reports and the Special Servicer’s reports and any information provided by the Trustee, without any duty or obligation to recompute, verify or recalculate any of the amounts and other information stated therein.

(e)         The Special Servicer shall deliver to the Master Servicer the reports and information required of the Special Servicer pursuant to Section 3.12(b) and Section 3.12(c), and the Master Servicer shall deliver or make available to the Certificate Administrator the reports and data files set forth in Section 3.12(b). The Master Servicer may, absent manifest error, conclusively rely on the reports and/or data to be provided by the Special Servicer pursuant to Section 3.12(b) and Section 3.12(c). The Certificate Administrator may, absent manifest error, conclusively rely on the reports and/or data to be provided by the Master Servicer pursuant to Section 3.12(b). In the case of information or reports to be furnished by the Master Servicer to the Certificate Administrator pursuant to Section 3.12(b), to the extent that such information or reports are, in turn, based on information or reports to be provided by the Special Servicer pursuant to Section 3.12(b) or Section 3.12(c) and to the extent that such reports are to be prepared and delivered by the Special Servicer pursuant to Section 3.12(b) or Section 3.12(c), the

 -275-

Master Servicer shall have no obligation to provide such information or reports to the Certificate Administrator until it has received the requisite information or reports from the Special Servicer, and the Master Servicer shall not be in default hereunder due to a delay in providing the reports required by Section 3.12(b) caused by the Special Servicer’s failure to timely provide any information or report required under Section 3.12(b) or Section 3.12(c) of this Agreement.

(f)          Notwithstanding the foregoing, however, the failure of the Master Servicer or the Special Servicer to disclose any information otherwise required to be disclosed by this Section 3.12 shall not constitute a breach of this Section 3.12 to the extent the Master Servicer or the Special Servicer so fails because such disclosure, in the reasonable belief of the Master Servicer or the Special Servicer, as the case may be, would violate any applicable law or any provision of a Mortgage Loan document prohibiting disclosure of information with respect to the Mortgage Loans or Mortgaged Properties. The Master Servicer and the Special Servicer may disclose any such information or any additional information to any Person so long as such disclosure is consistent with applicable law and the Servicing Standard. The Master Servicer or the Special Servicer may affix to any information provided by it any disclaimer it deems appropriate in its reasonable discretion (without suggesting liability on the part of any other party hereto).

(g)         Unless otherwise specifically stated herein, if the Master Servicer or the Special Servicer is required to deliver any statement, report or information under any provisions of this Agreement, the Master Servicer or the Special Servicer, as the case may be, may satisfy such obligation by (x) physically delivering a paper copy of such statement, report or information, (y) delivering such statement, report or information in a commonly used electronic format or (z) except with respect to information to be provided to the Certificate Administrator or any Companion Holder and, prior to the occurrence of a Consultation Termination Event, the Directing Holder, making such statement, report or information available on the Master Servicer’s or the Special Servicer’s Internet website, unless this Agreement expressly specifies a particular method of delivery.

Notwithstanding anything to the contrary in the foregoing, the Master Servicer and the Special Servicer shall deliver any required statements, reports or other information to the Certificate Administrator in an electronic format mutually agreeable to the Certificate Administrator and the Master Servicer or the Special Servicer, as the case may be. The Master Servicer or the Special Servicer may physically deliver a paper copy of any such statement, report or information as a temporary measure due to system problems, however, copies in electronic format shall follow upon the correction of such system problems.

Section 3.13     Access to Certain Information.   (a) Each of the Master Servicer and the Special Servicer shall provide or cause to be provided to the Certificate Administrator, and the Certificate Administrator shall afford access to any Mortgage Loan Seller and to any Certificateholder that is a federally insured financial institution, the OCC, the FDIC, the Board of Governors of the Federal Reserve System of the United States of America and the supervisory agents and examiners of such boards and such corporations, and any other federal or state banking or insurance regulatory authority that may exercise authority over any such Certificateholder, and to each Holder of a Non-Registered Certificate, access to any documentation or information regarding the Mortgage Loans (other than any Non-Serviced

 -276-

Mortgage Loan) and, in the case of a Mortgage Loan that is a portion of a Serviced Whole Loan, the related Companion Loan, and the Trust within its control which may be required by applicable law. At the election of the Master Servicer, the Special Servicer or the Certificate Administrator, such access may be afforded to such Person identified above by the delivery of copies of information as requested by such Person and the Master Servicer, the Special Servicer or the Certificate Administrator shall be permitted to require payment (other than from the Directing Holder (prior to the occurrence of a Consultation Termination Event) and the Trustee and the Certificate Administrator on its own behalf or on behalf of the Certificateholders, as applicable) of a sum sufficient to cover the reasonable out-of-pocket costs incurred by it in making such copies. Such access shall (except as described in the preceding sentence) be afforded without charge but only upon reasonable prior written request and during normal business hours at the offices of the Certificate Administrator or the Custodian.

The failure of the Master Servicer or the Special Servicer to provide access as provided in this Section 3.13 as a result of a confidentiality obligation shall not constitute a breach of this Section 3.13. In connection with providing information pursuant to this Section 3.13, the Master Servicer and the Special Servicer may each (i) affix a reasonable disclaimer to any information provided by it for which it is not the original source (without suggesting liability on the part of any other party hereto); (ii) affix to any information provided by it a reasonable statement regarding securities law restrictions on such information and/or condition access to information on (x) the execution of a confidentiality agreement substantially in the form of Exhibit X, or (y) execution of a “click-through” confidentiality agreement if such information is being provided through the Master Servicer’s or the Special Servicer’s website; (iii) withhold access to confidential information or any intellectual property; and/or (iv) withhold access to items of information contained in the Servicing File for any Mortgage Loan if the disclosure of such items is prohibited by applicable law or the provisions of any related Mortgage Loan documents or would constitute a waiver of the attorney-client privilege. Notwithstanding any provision of this Agreement to the contrary, the failure of the Master Servicer or the Special Servicer to disclose any information otherwise required to be disclosed by it pursuant to this Agreement shall not constitute a breach of this Agreement to the extent that the Master Servicer or the Special Servicer, as the case may be, determines, in its reasonable good faith judgment consistent with the applicable Servicing Standard, that such disclosure would violate applicable law or any provision of a Mortgage Loan or Companion Loan document prohibiting disclosure of information with respect to the Mortgage Loans or Companion Loans or the Mortgaged Properties, constitute a waiver of the attorney-client privilege on behalf of the Trust or the Trust or otherwise materially harm the Trust or the Trust. Without limiting the generality of the foregoing, the Master Servicer or the Special Servicer may refrain from disclosing information that it reasonably determines would prejudice the interest of the Certificateholders with respect to a workout or exercise of remedies as to any particular Mortgage Loan or Trust Subordinate Companion Loan.

Upon the reasonable request of any Certificateholder or Certificate Owner (or with respect to any AB Subordinate Companion Loan, the holder of such AB Subordinate Companion Loan) that has delivered an Investor Certification to the Master Servicer or the Special Servicer, as applicable, the Master Servicer (with respect to Non-Specially Serviced Loans) or the Special Servicer (with respect to Specially Serviced Loans), as applicable, may provide (or forward electronically) at the expense of such Certificateholder or holder of such AB

 -277-

Subordinate Companion Loan, as applicable, copies of any appraisals, operating statements, rent rolls and financial statements (in each case, solely relating to the related Serviced Whole Loan, if requested by the holder of an AB Subordinate Companion Loan or a Holder of any Loan-Specific Certificates) obtained by the Master Servicer or the Special Servicer, as the case may be; provided that, in connection with such request, the Master Servicer or the Special Servicer, as applicable, may require a written confirmation executed by the requesting Person substantially in such form as may be reasonably acceptable to the Master Servicer or the Special Servicer, as applicable, generally to the effect that such Person will keep such information confidential and shall use such information only for the purpose of analyzing asset performance and evaluating any continuing rights the Certificateholder or holder of such AB Subordinate Companion Loan, as applicable, may have under this Agreement. In addition, upon the reasonable request of any Controlling Class Certificateholder identified to the Master Servicer (in the case of a Non-Specially Serviced Loan) or the Special Servicer (in the case of a Specially Serviced Loan) to the Master Servicer’s or the Special Servicer’s reasonable satisfaction and if the requested information is in the Master Servicer’s or the Special Servicer’s possession, the Master Servicer or the Special Servicer, as applicable, shall provide or make available (or forward electronically) to such Controlling Class Certificateholder (at the expense of such Controlling Class Certificateholder) any Excluded Information (available to Privileged Persons through the Certificate Administrator’s Website but not accessible to such Controlling Class Certificateholder through the Certificate Administrator’s Website on account of it constituting Excluded Information) relating to any Excluded Controlling Class Loan with respect to which such Controlling Class Certificateholder is not an Excluded Controlling Class Holder; provided that, in connection therewith, the Master Servicer or the Special Servicer may require a written confirmation executed by the requesting Person substantially in such form as may be reasonably acceptable to the Master Servicer or the Special Servicer, generally to the effect that such Person is a Controlling Class Certificateholder, will keep such Excluded Information confidential and is not a Borrower Party, upon which the Master Servicer or the Special Servicer may conclusively rely. In addition, the Master Servicer and the Special Servicer shall be entitled to conclusively rely on delivery from a Controlling Class Certificateholder of an investor certification substantially in the form of Exhibit P-1E that such Controlling Class Certificateholder is not an Excluded Controlling Class Holder with respect to a particular Mortgage Loan.

Notwithstanding anything to the contrary herein (other than as permitted in the preceding paragraph with respect to any Certificateholder or as specifically provided for herein with respect to the Directing Certificateholder), unless required by applicable law or court order, no Certificateholder or beneficial owner shall be given access to, or be provided copies of, the Mortgage Files or Diligence Files.

Section 3.14     Title to REO Property; REO Account.   (a) If title to any Mortgaged Property is acquired (and thus becomes REO Property), the deed or certificate of sale shall be issued in the name of the Trust where permitted by applicable law or regulation and consistent with customary servicing procedures, and otherwise, in the name of the Trustee or its nominee on behalf of the Certificateholders and, if applicable, on behalf of the related Companion Holders, in the case of a Serviced Companion Loan.

The Special Servicer, on behalf of the Trust and, if applicable, the related Serviced Companion Noteholder, shall sell any REO Property prior to the close of the third calendar year following the year in which the Trust acquires ownership of such REO Property, within the meaning of Treasury Regulations Section 1.856-6(b)(1), for purposes of Section 860G(a)(8) of the Code, unless the Special Servicer either (i) applies for an extension of time no later than sixty (60) days prior to the close of the third calendar year in which it acquired ownership (or the period provided in the then-applicable REMIC Provisions) and such qualifying extension is granted or is not denied (an “REO Extension”) by the Internal Revenue Service to sell such REO Property or (ii) obtains for the Trustee and the Certificate Administrator an Opinion of Counsel, addressed to the Trustee and the Certificate Administrator, to the effect that the holding by the Trust of such REO Property subsequent to the close of the third calendar year following the year in which acquisition occurred will not cause an Adverse REMIC Event to occur. If the Special Servicer is granted or not denied the REO Extension contemplated by clause (i) of the immediately preceding sentence or obtains the Opinion of Counsel contemplated by clause (ii) of the immediately preceding sentence, the Special Servicer shall sell such REO Property within such longer period as is permitted by such REO Extension or such Opinion of Counsel, as the case may be. Any expense incurred by the Special Servicer in connection with its being granted the REO Extension contemplated by clause (i) of the second preceding sentence or its obtaining the Opinion of Counsel contemplated by clause (ii) of the second preceding sentence, shall be an expense of the Trust payable out of the Collection Account pursuant to Section 3.05(a).

(b)         The Special Servicer shall segregate and hold all funds collected and received in connection with any REO Property separate and apart from its own funds and general assets. If an REO Acquisition shall occur, the Special Servicer shall establish and maintain one or more REO Accounts, held on behalf of the Trustee for the benefit of the Certificateholders and, if applicable, on behalf of any related Companion Holder(s), as applicable, as their interest shall appear, and the Trustee (as holder of the Lower-Tier Regular Interests), for the retention of revenues and other proceeds derived from each REO Property. The REO Account shall be an Eligible Account. The Special Servicer shall deposit, or cause to be deposited, in the REO Account, within one (1) Business Day after receipt of properly identified funds, all REO Revenues, Insurance and Condemnation Proceeds and Liquidation Proceeds received in respect of an REO Property. Funds in the REO Account may be invested in Permitted Investments in accordance with Section 3.06. The Special Servicer shall give notice to the Trustee, the Certificate Administrator, and the Master Servicer of the location of the REO Account when first established and of the new location of the REO Account prior to any change thereof.

 -291-

(c)         The Special Servicer shall withdraw from the REO Account funds necessary for the proper operation, management, insuring, leasing, maintenance and disposition of any REO Property, but only to the extent of amounts on deposit in the REO Account relating to such REO Property. On the later of the date that is (x) on or prior to each Determination Date or (y) two (2) Business Days after such amounts are received and properly identified and determined to be available (or, with respect to a Serviced Companion Loan (other than any Trust Subordinate Companion Loan), on the Business Day preceding each Serviced Whole Loan Remittance Date), the Special Servicer shall withdraw from the REO Account and remit to the Master Servicer, which shall deposit into the Collection Account (or the Companion Distribution Account, as applicable), the aggregate of all amounts received in respect of each REO Property during the one-month period ending on such Determination Date, net of (i) any withdrawals made out of such amounts pursuant to the preceding sentence and (ii) Net Investment Earnings on amounts on deposit in the REO Account; provided, however, that the Special Servicer may retain in such REO Account, in accordance with the Servicing Standard, such portion of such balance as may be necessary to maintain a reasonable reserve for repairs, replacements, leasing, management and tenant improvements and other related expenses for the related REO Property. In addition, on or prior to each Determination Date (or with respect to a Serviced Companion Loan, on the Business Day preceding each Serviced Whole Loan Remittance Date), the Special Servicer shall provide the Master Servicer with a written accounting of amounts remitted to the Master Servicer for deposit in the Collection Account, as applicable, on such date. The Master Servicer shall apply all such amounts as instructed by the Special Servicer on the Determination Date (or with respect to a Serviced Companion Loan, on each Serviced Whole Loan Remittance Date) for the related Distribution Date.

(d)         The Special Servicer shall keep and maintain separate records, on a property-by-property basis, for the purpose of accounting for all deposits to, and withdrawals from, the REO Account pursuant to Section 3.14(b) or Section 3.14(c).

(e)         With respect to the Trust Subordinate Companion Loans, references to actions being taken for the benefit of any such Companion Loan in this Section 3.14 shall be deemed to be taken also for the benefit of the Holders of the related Loan-Specific Certificates, as beneficial owners of such Companion Loan.

Section 3.15     Management of REO Property.  (a) If title to any REO Property is acquired, the Special Servicer shall manage, conserve, protect, operate and lease such REO Property (other than any Non-Serviced Mortgaged Property) for the benefit of the Certificateholders and the related Companion Holders, as applicable, and the Trustee (as holder of the Lower-Tier Regular Interests and Trust Subordinate Companion Loan REMIC Regular Interests) solely for the purpose of its timely disposition and sale in a manner that does not cause such REO Property to fail to qualify as “foreclosure property” within the meaning of Section 860G(a)(8) of the Code or result in the receipt by the Trust or any Serviced Companion Noteholder of any “income from non-permitted assets” within the meaning of Section 860F(a)(2)(B) of the Code or result in an Adverse REMIC Event. Subject to the foregoing, however, the Special Servicer shall have full power and authority to do any and all things in connection therewith as are in the best interests of and for the benefit of the Certificateholders (and, in the case of each Serviced Whole Loan, the related Companion Holder(s)) and the Trustee (as holder of the Lower-Tier Regular Interests and the Trust

 -292-

Subordinate Companion Loan REMIC Regular Interests) all as a collective whole (taking into account the subordinate or pari passu nature of any Companion Loan, as the case may be) (as determined by the Special Servicer in its reasonable judgment in accordance with the Servicing Standard). Notwithstanding anything to the contrary herein, REO Property with respect to a Non-Serviced Mortgage Loan is excluded for all purposes of this Section 3.15. Subject to this Section 3.15, the Special Servicer may allow the Trust or any commercial mortgage securitization that holds any Serviced Companion Loan to earn “net income from foreclosure property” within the meaning of Section 860G(d) of the Code if it determines that earning such income is in the best interests of Certificateholders and, if applicable, any related Companion Holder(s) on a net after-tax basis as compared with net leasing such REO Property or operating such REO Property on a different basis. In connection therewith, the Special Servicer shall deposit or cause to be deposited on a daily basis (and in no event later than one (1) Business Day following receipt of such properly identified funds) in the applicable REO Account all revenues received by it with respect to each REO Property and the related REO Loan, and shall withdraw from the REO Account, to the extent of amounts on deposit therein with respect to such REO Property, funds necessary for the proper operation, management, leasing and maintenance of such REO Property, including, without limitation:

(i)          all insurance premiums due and payable in respect of such REO Property;

(ii)         all real estate taxes and assessments in respect of such REO Property that may result in the imposition of a lien thereon;

(iii)        any ground rents in respect of such REO Property, if applicable; and

(iv)        all costs and expenses necessary to maintain and lease such REO Property.

To the extent that amounts on deposit in the REO Account in respect of any REO Property are insufficient for the purposes set forth in clauses (i) through (iv) above with respect to such REO Property, the Master Servicer (subject to receiving notice from the Special Servicer in accordance with the procedures set forth elsewhere in this Agreement) shall advance from its own funds such amount as is necessary for such purposes unless (as evidenced by an Officer’s Certificate delivered to the Trustee, the Special Servicer, the Depositor, the Certificate Administrator and the Directing Holder (with respect to the Directing Holder, in respect of any Mortgage Loan other than an Excluded Loan as to such party or a Trust Subordinate Companion Loan, and prior to the occurrence and continuance of a Consultation Termination Event)) such advances would, if made, constitute Nonrecoverable Servicing Advances.

(b)         Without limiting the generality of the foregoing, the Special Servicer shall not:

(i)          permit the Trust to enter into, renew or extend any New Lease with respect to any REO Property, if the New Lease by its terms will give rise to any income that does not constitute Rents from Real Property;

(ii)         permit any amount to be received or accrued under any New Lease other than amounts that will constitute Rents from Real Property;

 -293-

(iii)        authorize or permit any construction on any REO Property, other than the completion of a building or other improvement thereon, and then only if more than 10% of the construction of such building or other improvement was completed before default on the related Mortgage Loan or Trust Subordinate Companion Loan, if applicable, became imminent, all within the meaning of Section 856(e)(4)(B) of the Code; or

(iv)        Directly Operate, or allow any other Person, other than an Independent Contractor, to Directly Operate, any REO Property on any date more than ninety (90) days after its acquisition date;

unless, in any such case, the Special Servicer has obtained an Opinion of Counsel (the cost of which shall be paid by the Master Servicer as a Servicing Advance) to the effect that such action will not cause such REO Property to fail to qualify as “foreclosure property” within the meaning of Section 860G(a)(8) of the Code at any time that it is held for the benefit of the Trust, in which case the Special Servicer may take such actions as are specified in such Opinion of Counsel. The Special Servicer shall cause any Mortgaged Property acquired as an REO Property to be operated and managed in a manner that would, reasonable judgment exercised in accordance with the Servicing Standard and to the extent commercially feasible, maximize the Trust’s net after-tax proceeds from such property.

(c)          The Special Servicer shall contract with any Independent Contractor for the operation and management of any REO Property within ninety (90) days of the acquisition date thereof, provided that:

(i)          the terms and conditions of any such contract may not be inconsistent herewith and shall reflect an agreement reached at arm’s length;

(ii)         the fees of such Independent Contractor (which shall be an expense of the Trust) shall be reasonable and customary in light of the nature and locality of the Mortgaged Property;

(iii)        any such contract shall require, or shall be administered to require, that the Independent Contractor (A) pay all costs and expenses incurred in connection with the operation and management of such REO Property, including, without limitation, those listed in subsection (a) hereof, and (B) remit all related revenues collected (net of its fees and such costs and expenses) to the Special Servicer upon receipt;

(iv)        none of the provisions of this Section 3.15(c) relating to any such contract or to actions taken through any such Independent Contractor shall be deemed to relieve the Special Servicer of any of its duties and obligations hereunder with respect to the operation and management of any such REO Property; and

(v)         the Special Servicer shall be obligated to manage and supervise such Independent Contractor in accordance with the Servicing Standard.

The Special Servicer shall be entitled to enter into any agreement with any Independent Contractor performing services for it related to its duties and obligations hereunder

 -294-

for indemnification of the Special Servicer by such Independent Contractor, and nothing in this Agreement shall be deemed to limit or modify such indemnification.

(d)         When and as necessary, the Special Servicer shall send to the Trustee, the Certificate Administrator and the Master Servicer a statement prepared by the Special Servicer setting forth the amount of net income or net loss, as determined for federal income tax purposes, resulting from the operation and management of a trade or business on, the furnishing or rendering of a non-customary service to the tenants of, or the receipt of any other amount not constituting Rents from Real Property in respect of, any REO Property in accordance with Sections 3.15(a) and 3.15(b).

Section 3.16      Sale of Defaulted Loans and REO Properties.(a) (i) Within thirty (30) days after a Defaulted Loan has become a Specially Serviced Loan, the Special Servicer shall order (but shall not be required to have received) an Appraisal and within thirty (30) days of receipt of the Appraisal shall determine the fair value of such Defaulted Loan in accordance with the Servicing Standard; provided, however, that if the Special Servicer is then in the process of obtaining an Appraisal with respect to the related Mortgaged Property, the Special Servicer shall make its fair value determination as soon as reasonably practicable (but in any event within thirty (30) days) after its receipt of such an Appraisal. The Special Servicer may, from time to time, adjust its fair value determination based upon changed circumstances, new information and other relevant factors, in each instance in accordance with a review of such circumstances and new information in accordance with the Servicing Standard; provided that the Special Servicer shall promptly notify the Master Servicer in writing of the initial fair value determination and any adjustment to its fair value determination.

(ii)         If any Mortgage Loan, Serviced Companion Loan subject to an Intercreditor Agreement is a Specially Serviced Loan or to the extent otherwise required pursuant to the terms of the related Intercreditor Agreement, then the Special Servicer shall promptly notify in writing the Master Servicer, any related Companion Holder and any related mezzanine lender, as applicable, of any events requiring notice under the Intercreditor Agreement in accordance with the terms thereof. Thereafter, any related Companion Holder and related mezzanine lender, as applicable, will, notwithstanding anything in this Section 3.16 to the contrary, have the option to purchase the related Mortgage Loan and cure defaults relating thereto as and to the extent set forth in the related Intercreditor Agreement.

(iii)        If any Mortgage Loan not subject to an Intercreditor Agreement becomes a Specially Serviced Loan, or if the related Companion Holder or related mezzanine lender, as applicable, for any such Mortgage Loan subject to an Intercreditor Agreement has not previously exercised the option to purchase the Mortgage Loan pursuant to the previous paragraph, the Special Servicer may offer to sell to any Person any Specially Serviced Loan (to the extent consistent with any related Intercreditor Agreement and Section 3.16(d)) or may offer to purchase any Specially Serviced Loan, if and when the Special Servicer determines, consistent with the Servicing Standard, that such a sale would be in the best economic interests of the Certificateholders (including the Holders of the Loan-Specific Certificates) or, if applicable, the Certificateholders and the Serviced Companion Noteholder(s) (as a collective whole as if the Trust and the Serviced

 -295-

Companion Loan Noteholder(s) constituted a single lender), on a net present value basis. In the case of any Non-Serviced Mortgage Loan, under certain limited circumstances permitted under the related Intercreditor Agreement, to the extent that such Non-Serviced Mortgage Loan is not sold together with the related Non-Serviced Companion Loan by the applicable Non-Serviced Special Servicer for the related Non-Serviced Whole Loan, the Special Servicer will be entitled to sell (with the consent of the Directing Certificateholder and after consulting with the Risk Retention Consultation Party pursuant to Section 6.08(a), in each case, if no Control Termination Event has occurred and is continuing and such Non-Serviced Mortgage Loan is not an Excluded Loan as to such party) such Non-Serviced Mortgage Loan if it determines in accordance with the Servicing Standard that such action would be in the best interests of the Certificateholders, and, subject to the terms of the related Intercreditor Agreement, the Special Servicer shall be entitled to the liquidation fee that the related Non-Serviced Special Servicer would have otherwise been entitled to in connection with the sale of such Non-Serviced Mortgage Loan. The Special Servicer is required to give the Trustee, the Certificate Administrator, the Master Servicer, the Operating Advisor (other than in respect of any applicable Excluded Loan) and the Directing Holder and the Risk Retention Consultation Party (in the case of the Directing Holder and the Risk Retention Consultation Party, other than in respect of any Excluded Loan as to such party) not less than ten (10) days’ prior written notice of its intention to sell any Defaulted Loan, in which case the Special Servicer is generally required to accept the highest offer received from any person for such Specially Serviced Loan in an amount at least equal to the outstanding principal balance plus all accrued and unpaid interest and outstanding costs and expenses and certain other amounts pursuant to this Agreement (the “Par Purchase Price”) or, at its option, if it has received no offer at least equal to the Par Purchase Price therefor, purchase such Specially Serviced Loan at such Par Purchase Price.

(iv)        (A) In the case of a Specially Serviced Loan as to which a default has occurred and is continuing, in the absence of any offer at least equal to the Par Purchase Price pursuant to clause (iii) above (or purchase by the Special Servicer for such price), the Special Servicer shall solicit offers and, subject to subclause (B) below, may accept the highest offer received from any Person that is determined by the Special Servicer to be a fair price for such Specially Serviced Loan, if the highest offeror is a Person other than an Interested Person. In determining whether any offer from a Person other than an Interested Person constitutes a fair price for any Defaulted Loan or REO Property, the Special Servicer shall take into account (in addition to the results of any Appraisal, updated Appraisal or narrative appraisal that it may have obtained pursuant to this Agreement within the prior 6 months), among other factors, the period and amount of the occupancy level and physical condition of the related Mortgaged Property and the state of the local economy. If the offeror is an Interested Person, the Trustee (based upon updated Appraisals ordered by the Special Servicer and received by the Trustee (or ordered by the Trustee if the Special Servicer or any of its Affiliates is an Interested Person)) shall determine the fair price unless (i) the offer is equal to or greater than the applicable Par Purchase Price and (ii) the offer is the highest offer received; provided, however, that no offer from an Interested Person will constitute a fair price unless (A) it is the highest offer received and (B) if the offer is less than the applicable Par Purchase Price, at least two other offers are received from independent third parties, and any such determination by the

 -296-

Trustee shall be binding upon all parties. The Trustee shall act in a commercially reasonable manner in making such determination. In determining whether any offer received from an Interested Person represents a fair price for any such Defaulted Loan, the Trustee shall rely on the most recent Appraisal (or update of such Appraisal) of the related Mortgaged Property conducted in accordance with this Agreement within the preceding 6-month period or, in the absence of any such Appraisal, on a new Appraisal. Except as provided in the following paragraph, the cost of any Appraisal will be covered by, and will be reimbursable as, a Servicing Advance.

Notwithstanding anything contained in the preceding paragraph to the contrary, if the Trustee is required to determine whether a cash offer by an Interested Person constitutes a fair price and the offer is less than the Par Purchase Price, the Trustee may, at its option, (at the expense of the Interested Person) designate an independent third party expert in real estate or commercial mortgage loan matters with at least 5 years’ experience in valuing or investing in loans similar to the subject Mortgage Loan or Serviced Whole Loan, as the case may be, that has been selected with reasonable care by the Trustee to determine if such cash offer constitutes a fair price for such Mortgage Loan or Serviced Whole Loan. If the Trustee designates such a third party to make such determination, the Trustee shall be entitled to rely conclusively upon such third party’s determination. The reasonable fees of, and the costs of all appraisals, inspection reports and broker opinions of value incurred by any such third party shall be covered by, and shall be reimbursable, from the offering Interested Person and the Special Servicer shall use efforts consistent with the Servicing Standard to collect payment from such Interested Person. If such expense is not paid by the applicable Interested Person within thirty (30) days of demand for payment, such expense shall be reimbursable to the Trustee by the Master Servicer as a Servicing Advance (provided that the Trustee shall not engage a third party expert whose fees exceed a commercially reasonable amount as determined by the Trustee) but the Special Servicer shall continue to use efforts consistent with the Servicing Standard to collect such amounts from the applicable Interested Person. Neither the Trustee, in its individual capacity, nor any of its Affiliates may make an offer for or purchase any Specially Serviced Loan.

(B)      The Special Servicer shall not be obligated to accept the highest offer if the Special Servicer determines (in consultation with the Directing Holder and the Risk Retention Consultation Party, subject to the limitations on consultation set forth in Section 6.08(a) (in each case, unless a Consultation Termination Event shall have occurred and be continuing and other than with respect to any Mortgage Loan that is an Excluded Loan as to such party) and, in the case of a Serviced Whole Loan or an REO Property related to a Serviced Whole Loan, the related Companion Holder), in accordance with the Servicing Standard (and subject to the requirements of any related Intercreditor Agreement), that the rejection of such offer would be in the best interests of the Holders of Certificates and, in the case of a sale of a Serviced Whole Loan, the related Companion Holder(s) (as a collective whole, as if such Certificateholders and, if applicable, the related Companion Holder(s) constituted a single lender). In addition, the Special Servicer may accept a lower offer if it determines, in accordance with the Servicing Standard (and

 -297-

subject to the requirements of any related Intercreditor Agreement), that the acceptance of such offer would be in the best interests of the Holders of Certificates (including the holders of the Loan-Specific Certificates) and, in the case of a sale of a Serviced Whole Loan, the related Companion Holder(s) (as a collective whole, as if such Certificateholders and, if applicable, the related Companion Holder constituted a single lender (and with respect to any AB Whole Loan, taking into account the subordinate nature of the related Subordinate Companion Loan)) (for example, if the prospective buyer making the lower offer is more likely to perform its obligations, or the terms offered by the prospective buyer making the lower offer are more favorable); provided that the offeror is not the Special Servicer or a Person that is an Affiliate of the Special Servicer. The Special Servicer shall use reasonable efforts to sell all Defaulted Loans prior to the Rated Final Distribution Date. For the avoidance of doubt, the Trustee shall have no obligation to make any fair value determination, to the extent required to do so pursuant to this Section 3.16, on the basis of anything other than the related Appraisal.

(v)         Unless and until any Specially Serviced Loan is sold pursuant to this Section 3.16(a), the Special Servicer shall pursue such other resolution strategies with respect to such Specially Serviced Loan, including, without limitation, workout and foreclosure, as the Special Servicer may deem appropriate, consistent with the Asset Status Report and the Servicing Standard and the REMIC Provisions.

(b)         (i) (A) The Special Servicer may purchase any REO Property at the Par Purchase Price therefor (in the case of a Serviced Whole Loan, such purchase shall be a purchase of the entire REO Property, including the portion relating to the related Companion Loan). The Special Servicer may also offer to sell to any Person any REO Property (in the case of a Serviced Whole Loan, such sale shall be a sale of the entire REO Property, including the portion relating to the related Companion Loan), if and when the Special Servicer determines, consistent with the Servicing Standard, that such a sale would be in the best economic interest of the Trust and the related Companion Holders. The Special Servicer shall give the Trustee, the Master Servicer, each Companion Holder, the Certificate Administrator and the Directing Holder and the Risk Retention Consultation Party (in the case of the Directing Holder and the Risk Retention Consultation Party, in respect of any Mortgage Loan other than an Excluded Loan as to such party and prior to the occurrence and continuance of a Consultation Termination Event) not less than ten (10) days’ prior written notice of the Purchase Price and its intention to (i) purchase any REO Property at the Par Purchase Price therefor or (ii) sell any REO Property, in which case the Special Servicer shall accept the highest offer received from any Person for any REO Property in an amount at least equal to the Par Purchase Price therefor. To the extent permitted by applicable law, and subject to the Servicing Standard, the Master Servicer, an Affiliate of the Master Servicer, the Special Servicer or an Affiliate of the Special Servicer, or an employee of either of them may act as broker in connection with the sale of any REO Property and may retain from the proceeds of such sale a brokerage commission that does not exceed the commission that would have been earned by an independent broker pursuant to a brokerage agreement entered into at arm’s length.

 -298-

(B)      In the absence of any such offer as set forth in subclause (A) above, the Special Servicer shall, subject to subclause (C) below, accept the highest offer for such REO Property received from any Person that is determined to be a fair price (1) by the Special Servicer, if the highest offeror is a Person other than an Interested Person, or (2) by the Trustee, if the highest offeror is an Interested Person unless (i) the offer is equal to or greater than the applicable Purchase Price and (ii) the offer is the highest offer received; provided, however, that no offer from an Interested Person will constitute a fair price unless (A) it is the highest offer received and (B) if the offer is less than the applicable Par Purchase Price, at least two other offers are received from independent third parties. Notwithstanding anything to the contrary herein, neither the Trustee, in its individual capacity, nor any of its Affiliates may make an offer for or purchase any REO Property pursuant hereto.

(C)      The Special Servicer shall not be obligated by either of the foregoing paragraphs or otherwise to accept the highest offer if the Special Servicer determines, in accordance with the Servicing Standard, that rejection of such offer would be in the best interests of the Certificateholders and, with respect to any Serviced Whole Loan or the related Companion Holder, and in either case, as a collective whole (taking into account the subordinate or pari passu nature of any Serviced Companion Loans). In addition, the Special Servicer may accept a lower offer if it determines, in accordance with the Servicing Standard, that acceptance of such offer would be in the best interests of the Certificateholders and, with respect to any Serviced Whole Loan or the related Companion Holder, and in either case, as a collective whole (taking into account the subordinate or pari passu nature of any Serviced Companion Loans) (for example, if the prospective buyer making the lower offer is more likely to perform its obligations, or the terms offered by the prospective buyer making the lower offer are more favorable); provided that the offeror is not the Special Servicer or a Person that is an Affiliate of the Special Servicer.

(D)      In determining whether any offer received from an Interested Person represents a fair price for any REO Property, the Trustee shall obtain and may conclusively rely on the opinion of an Independent appraiser or other Independent expert in real estate matters retained by the Trustee in connection with making such determination. The reasonable cost of such Independent appraiser or other Independent expert shall be an expense of the offering Interested Person purchaser. The reasonable fees of and the costs of all appraisals, inspection reports and broker opinions of value incurred by any such third party shall be covered by, and shall be reimbursable, from the offering Interested Person and the Special Servicer shall use efforts consistent with the Servicing Standard to collect payment from such Interested Person. If such expense is not paid by the applicable Interested Person within thirty (30) days of demand for payment, such expense shall be reimbursable to the Trustee by the Master Servicer as a Servicing Advance but the Special Servicer shall continue to use efforts consistent with the Servicing Standard to collect such amounts from the applicable Interested Person. In determining whether any offer

 -299-

constitutes a fair price for any REO Property, the Special Servicer or the Trustee (or, if applicable, such appraiser) shall take into account, and any appraiser or other expert in real estate matters shall be instructed to take into account, as applicable, among other factors, the physical condition of such REO Property, the state of the local economy and the Trust’s obligation to comply with REMIC Provisions.

(ii)         Subject to the Servicing Standard, the Special Servicer shall act on behalf of the Trust and the related Companion Holders in negotiating and taking any other action necessary or appropriate in connection with the sale of any REO Property, including the collection of all amounts payable in connection therewith. A sale of any REO Property shall be without recourse to, or representation or warranty by, the Trustee, the Depositor, the Master Servicer, the Special Servicer, the Certificate Administrator, the Operating Advisor or the Trust (except that any contract of sale and assignment and conveyance documents may contain customary warranties of title, so long as the only recourse for breach thereof is to the Trust) and, if consummated in accordance with the terms of this Agreement, none of the Master Servicer, the Special Servicer, the Depositor, the Certificate Administrator, the Operating Advisor nor the Trustee shall have any liability to the Trust or any Certificateholder or related Companion Holder (if applicable) with respect to the purchase price therefor accepted by the Special Servicer or the Trustee.

(c)         Any sale of a Defaulted Loan or any REO Property shall be for cash only (unless changes in the REMIC Provisions or authoritative interpretations thereof made or issued subsequent to the Startup Day allow a sale for other consideration).

(d)         With respect to each Serviced Pari Passu Whole Loan, pursuant to the terms of the related Intercreditor Agreement and this Agreement, if the related Serviced Pari Passu Whole Loan becomes a Defaulted Loan, and if the Special Servicer determines to sell the related Mortgage Loan that has become a Defaulted Loan in accordance with this Section 3.16, then the Special Servicer shall sell the related Serviced Pari Passu Companion Loan (and, in the case of the Yorkshire & Lexington Towers Whole Loan, the Y&L Towers Trust Subordinate Companion Loan and, in the case of The Standard Highline NYC Whole Loan, the Standard Highline Trust Subordinate Companion Loan) together with such Mortgage Loan as one whole loan and shall require that all offers be submitted to the Special Servicer in writing. To the extent a determination is required to be made hereunder as to whether any cash offer constitutes a fair price for any Serviced Whole Loan, such determination shall be made by the Trustee if the offeror is an Interested Person. Notwithstanding the foregoing, the Special Servicer shall not be permitted to sell the related Mortgage Loan together with the related Serviced Pari Passu Companion Loan(s) if it becomes a defaulted Whole Loan without the written consent of the holder of the related Serviced Pari Passu Companion Loan (provided that such consent is not required if the holder of the Serviced Pari Passu Companion Loan is the Mortgagor or an affiliate of the Mortgagor) unless the Special Servicer has delivered to the holder of the related Serviced Pari Passu Companion Loan: (a) at least fifteen (15) Business Days prior written notice of any decision to attempt to sell such Serviced Whole Loan; (b) at least ten (10) days prior to the permitted sale date, a copy of each bid package (together with any material amendments to such bid packages) received by the Special Servicer in connection with any such proposed sale; (c) at least ten (10) days prior to the proposed sale date, a copy of the most recent appraisal for such

 -300-

Serviced Pari Passu Whole Loan, and any documents in the servicing file reasonably requested by the holder of the related Serviced Pari Passu Companion Loan that are material to the sale price of the Serviced Pari Passu Whole Loan; and (d) until the sale is completed, and a reasonable period of time (but no less time than is afforded to other offerors and the Directing Certificateholder and the Risk Retention Consultation Party) prior to the proposed sale date, all information and other documents being provided to other offerors and all leases or other documents that are approved by the Master Servicer or the Special Servicer in connection with the proposed sale. The holder of the related Serviced Pari Passu Companion Loan (or its representative) will be permitted to submit an offer at any sale of such Whole Loan; however, the related Mortgagor and its agents and Affiliates shall not be permitted to submit an offer at such sale. Notwithstanding the foregoing, with respect to each Serviced Whole Loan, the holder of the related Companion Loan may waive any of the delivery or timing requirements set forth in this paragraph with respect to the related Whole Loan. If the Trustee is required to determine whether a cash offer by an Interested Person constitutes a fair price, the Trustee may (at its option and at the expense of the offering Interested Person purchaser) designate an independent third party expert in real estate or commercial mortgage loan matters with at least 5 years’ experience in valuing or investing in loans similar to the subject Mortgage Loan, that has been selected with reasonable care by the Trustee to determine if such cash offer constitutes a fair price for such Mortgage Loan. The Trustee shall act in a commercially reasonable manner in making such determination. If the Trustee designates such a third party to make such determination, the Trustee shall be entitled to rely conclusively upon such third party’s determination. The reasonable fees of, and the costs of all appraisals, inspection reports and broker opinions of value incurred by any such third party shall be covered by, and shall be reimbursable, from the offering Interested Person and the Special Servicer shall use efforts consistent with the Servicing Standard to collect payment from such Interested Person. If such expense is not paid by the applicable Interested Person within thirty (30) days of demand for payment, such expense shall be reimbursable to the Trustee by the Master Servicer as a Servicing Advance but the Special Servicer shall continue to use efforts consistent with the Servicing Standard to collect such amounts from the applicable Interested Person.

(e)         (i) Notwithstanding anything in this Section 3.16 to the contrary, (A) pursuant to the terms of the related Intercreditor Agreement, the holder of the related AB Subordinate Companion Loan (other than with respect to the Trust Subordinate Companion Loans) for each applicable Serviced Whole Loan and (B) pursuant to Section 3.32 herein, the Holder of the Standard Highline Non-Trust Junior Subordinate Companion Loan, will have the right to purchase the related Mortgage Loan or related REO Property, as applicable. Such right of the holder of the AB Subordinate Companion Loan shall be given priority over any provision described in this Section 3.16 as and to the extent set forth in the related Intercreditor Agreement. If the related Mortgage Loan or related REO Property is purchased by the holder of such AB Subordinate Companion Loan, repurchased by the applicable Mortgage Loan Seller or otherwise ceases to be subject to this Agreement, the related AB Subordinate Companion Loan (other than a Trust Subordinate Companion Loan that is not purchased together with such Mortgage Loan) will no longer be subject to this Agreement. If no AB Control Appraisal Period exists, the Special Servicer may not sell the AB Subordinate Companion Loan without the prior consent of the holder of the AB Subordinate Companion Loan. If an AB Control Appraisal Period has occurred and is continuing, the Special Servicer has the right (but not the obligation) to sell the

 -301-

AB Subordinate Companion Loan without the consent of the holder of the AB Subordinate Companion Loan.

(ii)         Notwithstanding anything in this Section 3.16 to the contrary, any mezzanine lender will have the right to purchase the related Mortgage Loan or REO Property, as applicable, and cure defaults relating thereto, as and to the extent set forth in the related Intercreditor Agreement.

(f)          Unless otherwise provided in an Intercreditor Agreement the sale of any Mortgage Loan pursuant to this Section 3.16 will be on a servicing released basis.

(g)         In the event the Master Servicer or the Special Servicer has the right to purchase any Companion Loan on behalf of the Trust pursuant to the related Intercreditor Agreement, neither the Master Servicer nor the Special Servicer shall exercise such right.

Section 3.17     Additional Obligations of Master Servicer and Special Servicer.   (a) The Master Servicer shall deliver all Compensating Interest Payments (other than the portion of any Compensating Interest Payment allocated to a Serviced Pari Passu Companion Loan or Trust Subordinate Companion Loan) to the Certificate Administrator for deposit in the Lower-Tier REMIC Distribution Account on each P&I Advance Date, without any right of reimbursement therefor. The Master Servicer shall deliver the portion of any Compensating Interest Payment allocated to a Serviced Pari Passu Companion Loan to the Companion Paying Agent for deposit in the Companion Distribution Account on each P&I Advance Date, without any right of reimbursement therefor. The Master Servicer shall deliver the portion of any Compensating Interest Payment allocated to a Trust Subordinate Companion Loan to the Certificate Administrator for deposit in the applicable Trust Subordinate Companion Loan REMIC Distribution Account on each P&I Advance Date, without any right of reimbursement therefor.

(b)         The Master Servicer or the Special Servicer, as applicable, shall provide to each Companion Holder any reports or notices required to be delivered to such Companion Holder pursuant to the related Intercreditor Agreement and the Master Servicer or Special Servicer, as applicable, shall provide to the Loan-Specific Directing Holder any reports or notices required to be delivered to the holder of Trust Subordinate Companion Loan pursuant to the related Intercreditor Agreement.

(c)         Upon the determination that a previously made Advance is a Nonrecoverable Advance, to the extent that the reimbursement thereof would exceed the full amount of the principal portion of general collections on the Mortgage Loans, and with respect to P&I Advances on a Trust Subordinate Companion Loan, would exceed the full amount of the principal portion of general collections allocated to the related Trust Subordinate Companion Loan, deposited in the Collection Account and available for distribution on the next Distribution Date, the Master Servicer or the Trustee, each at its own option and in its sole discretion, as applicable, instead of obtaining reimbursement for the remaining amount of such Nonrecoverable Advance pursuant to Section 3.05(a)(v) immediately, as an accommodation may elect to refrain from obtaining such reimbursement for such portion of the Nonrecoverable Advance during the one month collection period ending on the then-current Determination Date,

 -302-

for successive one-month periods for a total period not to exceed twelve (12) months (provided that, other than in the case of an Excluded Loan with respect to the Directing Holder or, if the Directing Holder is the Directing Certificateholder, the Holder of the majority of the Controlling Class, any such deferral exceeding six (6) months shall require, prior to the occurrence and continuance of any Control Termination Event, the consent of the Directing Holder), and any election to so defer or not to defer shall be deemed to be in accordance with the Servicing Standard. If the Master Servicer or the Trustee makes such an election at its sole option and in its sole discretion to defer reimbursement with respect to all or a portion of a Nonrecoverable Advance (together with interest thereon), then such Nonrecoverable Advance (together with interest thereon) or portion thereof shall continue to be fully reimbursable in the subsequent collection period (subject, again, to the same sole option to defer; it is acknowledged that, in such a subsequent period, such Nonrecoverable Advance shall again be payable first from principal collections as described above prior to payment from other collections). In connection with a potential election by the Master Servicer or the Trustee to refrain from the reimbursement of a particular Nonrecoverable Advance or portion thereof during the one month collection period ending on the related Determination Date for any Distribution Date, the Master Servicer or the Trustee shall further be authorized to wait for principal collections on the Mortgage Loans or the Trust Subordinate Companion Loans to be received until the end of such collection period before making its determination of whether to refrain from the reimbursement of a particular Nonrecoverable Advance or portion thereof); provided, however, that if, at any time the Master Servicer or the Trustee, as applicable, elects, in its sole discretion, not to refrain from obtaining such reimbursement or otherwise determines that the reimbursement of a Nonrecoverable Advance during a one-month collection period will exceed the full amount of the principal portion of general collections on the Mortgage Loans deposited in the Collection Account for such Distribution Date, then the Master Servicer or the Trustee, as applicable, shall use its reasonable efforts to give the 17g-5 Information Provider fifteen (15) days’ notice of such determination for posting on the 17g-5 Information Provider’s Website pursuant to Section 3.13(c), unless extraordinary circumstances make such notice impractical. Notwithstanding the foregoing, failure to give notice as required by the preceding sentence shall in no way affect the Master Servicer’s or the Trustee’s election whether to refrain from obtaining such reimbursement as described in this Section 3.17(c). Nothing herein shall give the Master Servicer or the Trustee the right to defer reimbursement of a Nonrecoverable Advance to the extent of any principal collections then available in the Collection Account pursuant to Section 3.05(a)(v).

The foregoing shall not, however, be construed to limit any liability that may otherwise be imposed on such Person for any failure by such Person to comply with the conditions to making such an election under Section 3.17 or to comply with the terms of Section 3.17 and the other provisions of this Agreement that apply once such an election, if any, has been made; provided, however, that the fact that a decision to recover such Nonrecoverable Advances over time, or not to do so, benefits some classes of Certificateholders to the detriment of other classes shall not, with respect to the Master Servicer or the Special Servicer, as applicable, constitute a violation of the Servicing Standard and/or with respect to the Trustee (solely in its capacity as Trustee), constitute a violation of any fiduciary duty to Certificateholders or any contractual obligation hereunder. If the Master Servicer or the Trustee, as applicable, determines, in its sole discretion, that its ability to fully recover the Nonrecoverable Advances has been compromised, then the Master Servicer or the Trustee, as

 -303-

applicable, shall be entitled to immediate reimbursement of Nonrecoverable Advances with interest thereon at the Reimbursement Rate from all amounts in the Collection Account for such Distribution Date (deemed first from principal and then interest). Any such election by any such party to refrain from reimbursing itself or obtaining reimbursement for any Nonrecoverable Advance or portion thereof with respect to any one or more collection periods shall not limit the accrual of interest at the Reimbursement Rate on such Nonrecoverable Advance for the period prior to the actual reimbursement of such Nonrecoverable Advance. The Master Servicer’s or the Trustee’s, as applicable, agreement to defer reimbursement of such Nonrecoverable Advances as set forth above is an accommodation to the Certificateholders and shall not be construed as an obligation on the part of the Master Servicer or the Trustee, as applicable, or a right of the Certificateholders. Nothing herein shall be deemed to create in the Certificateholders a right to prior payment of distributions over the Master Servicer’s or the Trustee’s, as applicable, right to reimbursement for Advances (deferred or otherwise) and accrued interest thereon. In all events, the decision to defer reimbursement or to seek immediate reimbursement of Nonrecoverable Advances shall be deemed to be in accordance with the Servicing Standard and none of the Master Servicer, the Trustee or the other parties to this Agreement shall have any liability to one another or to any of the Certificateholders or any of the Companion Holders for any such election that such party makes as contemplated by Section 3.17 or for any losses, damages or other adverse economic or other effects that may arise from such an election.

The aggregate of any Excess Prepayment Interest Shortfall with respect to the Mortgage Loans for any Distribution Date will be allocated on such Distribution Date among each class of Pooled Certificates, pro rata, in accordance with their respective Interest Accrual Amounts for that Distribution Date. Any Excess Prepayment Interest Shortfall with respect to a Trust Subordinate Companion Loan for any Distribution Date will be allocated on such Distribution Date to the related Loan-Specific Certificates, pro rata, in accordance with each Class’s accrued interest. Any Prepayment Interest Excess in respect of a Trust Subordinate Companion Loan shall be paid to the Master Servicer as additional servicing compensation.

(d)         With respect to any Mortgage Loan (or Serviced Whole Loan), if the related loan documents permit the lender to (but do not require the lender to), at its option, prior to an event of default under the related Mortgage Loan (or Serviced Whole Loan), apply amounts held in any reserve account as a prepayment or hold such amounts in a reserve account, the Master Servicer or the Special Servicer, as the case may be, may not apply such amounts as a prepayment, and will instead continue to hold such amounts in the applicable reserve account, unless not applying those amounts as a prepayment would be a violation of the Servicing Standard. Such amount may be used, if permitted under the loan documents, to defease the loan, or may be used to prepay the Mortgage Loan (or Serviced Whole Loan) or for other purpose consistent with the Servicing Standard and the loan documents, upon a subsequent default.

(e)         With respect to any modification or amendment of any Intercreditor Agreement related to a Serviced Whole Loan (to the extent received), the Master Servicer or the Special Servicer, as applicable, shall provide to the 17g-5 Information Provider a copy of any such modification or amendment, which the 17g-5 Information Provider shall promptly post on the 17g-5 Information Provider’s Website in accordance with Section 3.13(c).

If such extension would extend the Maturity Date of such Mortgage Loan and/or related Companion Loan for more than twelve (12) months from and after the original Maturity Date of such Mortgage Loan and/or related Companion Loan and such Mortgage Loan and/or related Companion Loan is not in default or default with respect thereto is not reasonably foreseeable, prior to any such extension, (1) the Master Servicer shall provide the Trustee, the Certificate Administrator, the Special Servicer, the Operating Advisor, the Directing Holder and the Risk Retention Consultation Party (in the case of the Directing Holder and the Risk Retention Consultation Party, (i) prior to the occurrence and continuance of a Consultation Termination Event and (ii) other than with respect to any Mortgage Loan that is an Excluded Loan as to such party), with an Opinion of Counsel (at the expense of the related Mortgagor to the extent permitted under the Mortgage Loan documents and, if not required or permitted to be paid by the Mortgagor, to be paid as an expense of the Trust in accordance with Section 3.11(d)) that such extension would not constitute a “significant modification” of the Mortgage Loan and/or Serviced Companion Loan within the meaning of Treasury Regulations Section 1.860G-2(b) and (2) subject to the Servicing Standard, the Special Servicer shall (A) obtain the consent of the Directing Holder and, with respect to Specially Serviced Loans, consult with the Risk Retention Consultation Party pursuant to Section 6.08(a) (in each case, (i) prior to the occurrence and continuance of a Control Termination Event and (ii) other than with respect to a Mortgage Loan that is an Excluded Loan as to such party) or (B) consult with the Directing Holder and the Risk Retention Consultation Party pursuant to Section 6.08(a) (in each case, (i) after the occurrence and during the continuance of a Control Termination Event, but (solely in the case of the Directing Holder) prior to a Consultation Termination Event and (ii) other than with respect to any Excluded Loan as to such party) (which consent or consultation shall be coordinated through the Special Servicer). Notwithstanding the foregoing, subject to the rights of the related Companion Holder to advise the Master Servicer with respect to, or consent to, such

 -305-

modification, waiver or amendment pursuant to the terms of the related Intercreditor Agreement, and subject to the Special Servicer’s processing rights pursuant to this subsection (a), the Master Servicer, with respect to Non-Specially Serviced Loans, without the consent of or consultation with the Special Servicer, the Operating Advisor or the Directing Holder, may modify or amend the terms of any Mortgage Loan and/or related Serviced Companion Loan in order to (i) cure any ambiguity or mistake therein, (ii) correct or supplement any provisions therein which may be inconsistent with any other provisions therein or correct any error or (iii) enter into any modification, waiver or amendment that does not constitute a Major Decision; provided that, if the Mortgage Loan (other than any Non-Serviced Mortgage Loan) and/or related Serviced Companion Loan is not in default or default with respect thereto is not reasonably foreseeable, such modification or amendment would not be a “significant modification” of the Mortgage Loan and/or related Serviced Companion Loan within the meaning of Treasury Regulations Section 1.860G-2(b).

Subject to Section 6.08, applicable law and the Mortgage Loan and/or related Serviced Companion Loan documents, neither the Master Servicer nor the Special Servicer shall permit the substitution of any Mortgaged Property (or any portion thereof) for one or more other parcels of real property at any time the Mortgage Loan and/or related Serviced Companion Loan is not in default pursuant to the terms of the related Mortgage Loan and/or related Serviced Companion Loan documents or default with respect thereto is not reasonably foreseeable unless (i) the Master Servicer or the Special Servicer, as the case may be, obtains Rating Agency Confirmation from each Rating Agency (and delivers such Rating Agency Confirmation to the Directing Holder and the Risk Retention Consultation Party, if permitted by the applicable Rating Agency) and a confirmation of any applicable rating agencies that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings of any class of Serviced Companion Loan Securities (if any) (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant to Section 3.25)) and (ii) such substitution would not be a “significant modification” of the Mortgage Loan and/or related Serviced Companion Loan within the meaning of Treasury Regulations Section 1.860G-2(b) or otherwise cause an Adverse REMIC Event (and the Master Servicer or the Special Servicer, as the case may be, may obtain and rely upon an Opinion of Counsel (at the expense of the related Mortgagor if not prohibited by the terms of the related Mortgage Loan documents, and if so prohibited, at the expense of the Trust) with respect thereto).

In connection with (i) the release of a Mortgaged Property (other than any Non-Serviced Mortgaged Property), or any portion of such Mortgaged Property from the lien of the related Mortgage or (ii) the taking of a Mortgaged Property (other than any Non-Serviced Mortgaged Property), or any portion of such Mortgaged Property by exercise of the power of eminent domain or condemnation, if the related Mortgage Loan documents require the Master Servicer or the Special Servicer, as applicable, to calculate (or to approve the calculation of the related Mortgagor of) the loan-to-value ratio of the remaining Mortgaged Property or Mortgaged Properties or the fair market value of the real property constituting the remaining Mortgaged Property or Mortgaged Properties, for purposes of REMIC qualification of the related Mortgage Loan, then such calculation shall, unless then permitted by the REMIC Provisions, exclude the value of personal property and going concern value, if any, as determined by an appropriate third party.

 -306-

If, following any such release or taking, the loan-to-value ratio as so calculated is greater than 125%, the Master Servicer or the Special Servicer, as applicable, shall require payment of principal by a “qualified amount” as determined under Revenue Procedure 2010-30 or successor provisions, unless the related Mortgagor provides an Opinion of Counsel that if such amount is not paid the related Mortgage Loan will not fail to be a Qualified Mortgage.

(b)         If the Special Servicer determines that a modification, waiver or amendment (including, without limitation, the forgiveness or deferral of interest or principal or the substitution of collateral pursuant to the terms of the Mortgage Loan (other than any Non-Serviced Mortgage Loan) and/or related Serviced Companion Loan or otherwise, the release of collateral or the pledge of additional collateral) of the terms of a Specially Serviced Loan with respect to which a payment default or other material default has occurred or a payment default or other material default is, in the Special Servicer’s judgment, reasonably foreseeable (as evidenced by an Officer’s Certificate of the Special Servicer), is reasonably likely to produce a greater (or equivalent) recovery on a net present value basis (the relevant discounting to be performed at the related Mortgage Rate) to the Trust and, if applicable, the related Companion Holders, as the holders of the related Serviced Companion Loan, than liquidation of such Specially Serviced Loan, then the Special Servicer may agree to a modification, waiver or amendment of such Specially Serviced Loan, subject to (x) the provisions of this Section 3.18(b) and Section 3.18(c), (y) the approval of the Directing Holder and consultation with the Risk Retention Consultation Party (in each case, with respect to any Mortgage Loan or Trust Subordinate Companion Loan other than any Excluded Loan as to such party, prior to the occurrence and continuance of a Control Termination Event (or after the occurrence and during the continuance of a Control Termination Event, but prior to a Consultation Termination Event, upon consultation with the Directing Certificateholder and the Risk Retention Consultation Party, and after the occurrence and during the continuance of a Consultation Termination Event, upon consultation with the Risk Retention Consultation Party)) as provided in Section 6.08; provided that with respect to any Pooled Serviced AB Whole Loan, prior to the occurrence and continuance of a related AB Control Appraisal Period, the approval of the holder of the related AB Subordinate Companion Loan, with respect to the Yorkshire & Lexington Towers Whole Loan, the Y&L Towers Directing Holder (prior to the related control termination event) or with respect to The Standard Highline NYC Whole Loan, the Standard Highline Directing Holder (prior to the related control termination event) will be required to the extent set forth in the related Intercreditor Agreement and the Directing Holder shall have no consent or consultation rights and the Risk Retention Consultation Party shall have no consultation rights regarding the matter; and (z) additionally, with respect to a Serviced Whole Loan, the rights of the related Serviced Companion Noteholder or with respect to a Mortgage Loan (other than any Non-Serviced Mortgage Loan) with mezzanine debt, the rights of the related mezzanine lender, to advise or consult with the Special Servicer with respect to, or consent to, such modification, waiver or amendment, in each case, pursuant to the terms of the related Intercreditor Agreement; provided that in the case of any release or substitution of collateral (other than a defeasance), the Special Servicer shall have obtained an Opinion of Counsel that such release or substitution would not be a “significant modification” of the Mortgage Loan within the meaning of Treasury Regulations Section 1.860G-2(b) or otherwise cause an Adverse REMIC Event. Notwithstanding anything herein to the contrary, with respect to any Excluded Loan with respect to the Directing Holder or, if the Directing Holder is the Directing Certificateholder, the Holder of the majority of the Controlling Class (regardless of whether an Operating Advisor Consultation Event has

 -307-

occurred and is continuing), the Special Servicer shall consult with the Operating Advisor, on a non-binding basis, in connection with the related transactions involving proposed Major Decisions that it is processing or for which its consent is required and consider alternative actions recommended by the Operating Advisor, in respect thereof, in accordance with the procedures set forth in Section 6.08 for consulting with the Operating Advisor.

The Special Servicer shall use its reasonable efforts to the extent possible to cause each Specially Serviced Loan to fully amortize prior to the Rated Final Distribution Date and shall not agree to a modification, waiver or amendment of any term of any Specially Serviced Loan if such modification, waiver or amendment would (1) extend the maturity date of any such Specially Serviced Loan to a date occurring later than the earlier of (a) five years (or with respect to the Yorkshire & Lexington Towers Whole Loan or the Standard Highline NYC Whole Loan, seven years) prior to the Rated Final Distribution Date and (b) if the Specially Serviced Loan is secured solely or primarily by a leasehold estate and not also the related fee interest, the date occurring twenty (20) years or, subject to (x) compliance with the Servicing Standard giving due consideration to the remaining term of the ground lease and (y) consultation rights relating to Major Decisions, ten (10) years prior to the expiration of such leasehold estate (including any options to extend such leasehold estate exercisable unilaterally by the related Mortgagor), or (2) provide for the deferral of interest unless interest accrues on the related Mortgage Loan, Trust Subordinate Companion Loan or Serviced Whole Loans generally at the related Mortgage Rate.

(c)         Any provision of this Section 3.18 to the contrary notwithstanding, except when a Mortgage Loan and/or Companion Loan is in default or default with respect thereto is reasonably foreseeable, no fee described in this Section 3.18 shall be collected by any Master Servicer or Special Servicer from a Mortgagor (or on behalf of the Mortgagor) in conjunction with any consent or any modification, waiver or amendment of a Mortgage Loan or Companion Loan, as applicable (unless the amount thereof is specified in the related Mortgage Note) if the collection of such fee would cause such consent, modification, waiver or amendment to be a “significant modification” of the Mortgage Note within the meaning of Treasury Regulations Section 1.860G-2(b).

(d)         To the extent consistent with this Agreement (including, without limitation, Section 3.08(a) and 3.08(b), the first sentence of Section 3.18(a), and Section 6.08), the Master Servicer (subject to the Special Servicer’s processing rights pursuant to Section 3.18(a) if any such waiver, modification or amendment constitutes a Major Decision) or the Special Servicer may, consistent with the Servicing Standard, agree to any waiver, modification or amendment of a Mortgage Loan and/or Serviced Companion Loan that is not in default or as to which default is not reasonably foreseeable only if the contemplated waiver, modification or amendment (i) will not be a “significant modification” of the Mortgage Loan within the meaning of Treasury Regulations Section 1.860G-2(b) and (ii) will not cause an Adverse REMIC Event to occur. In making this determination, the Master Servicer or Special Servicer may obtain and rely upon (and shall provide to the Trustee and the Certificate Administrator if obtained) an Opinion of Counsel (at the expense of the related Mortgagor or such other Person requesting such modification or, if such expense cannot be collected from the related Mortgagor or such other Person, to be paid out of the Collection Account pursuant to Section 3.05(a); provided that the Master Servicer or the Special Servicer, as the case may be, shall use its reasonable efforts to collect such fee from the Mortgagor or such other Person to the

 -308-

extent permitted under the related Mortgage Loan documents). Notwithstanding the foregoing, neither the Master Servicer nor the Special Servicer may waive the payment of any Yield Maintenance Charge or the requirement that any prepayment of a Mortgage Loan or Trust Subordinate Companion Loan be made on a Due Date, or if not made on a Due Date, be accompanied by all interest that would be due on the next Due Date with respect to any Mortgage Loan or Serviced Companion Loan that is not a Specially Serviced Loan.

(e)         Subject to Section 3.18(c), the Master Servicer and the Special Servicer each may, as a condition to its granting any request by a Mortgagor for consent, modification (including extensions), waiver or indulgence or any other matter or thing, the granting of which is within the Master Servicer’s or the Special Servicer’s, as the case may be, discretion pursuant to the terms of the instruments evidencing or securing the related Mortgage Loan or Companion Loan and is permitted by the terms of this Agreement, require that such Mortgagor pay to the Master Servicer or the Special Servicer, as the case may be, as additional servicing compensation, a reasonable or customary fee, for the additional services performed in connection with such request; provided that the charging of such fee is not a “significant modification” of the Mortgage Loan or Trust Subordinate Companion Loan within the meaning of Treasury Regulations Section 1.860G-2(b).

(f)          All modifications (including extensions), waivers and amendments of the Mortgage Loans and/or Companion Loans entered into pursuant to this Section 3.18 shall be in writing, signed by the Master Servicer or the Special Servicer, as the case may be, and the related Mortgagor (and by any guarantor of the related Mortgage Loan or Trust Subordinate Companion Loan, if such guarantor’s signature is required by the Special Servicer in accordance with the Servicing Standard).

(g)         With respect to any modification, waiver or amendment with respect to a Specially Serviced Loan, the Special Servicer shall notify the Master Servicer, the Trustee, the Certificate Administrator, the Operating Advisor (after the occurrence and during the continuance of an Operating Advisor Consultation Event), the Directing Holder and the Risk Retention Consultation Party (in the case of the Directing Holder, other than following the occurrence and continuance of a Consultation Termination Event, and in the case of the Directing Holder or the Risk Retention Consultation Party, other than with respect to any Excluded Loan as to such party), the applicable Companion Holder (unless, with respect to the holders of a Standard Highline Non-Trust Subordinate Companion Loan, a Standard Highline Non-Trust Junior Subordinate Companion Loan Control Appraisal Period or a Standard Highline Non-Trust Senior Subordinate Companion Loan Control Appraisal Period, as applicable, has occurred and is continuing or with respect to the holder of the Standard Highline Trust Subordinate Companion Loan, a Standard Highline Trust Subordinate Companion Loan Control Termination Event has occurred and is continuing), the related Mortgage Loan Seller (if such Mortgage Loan Seller is not a Master Servicer or Sub-Servicer of such Mortgage Loan, the Directing Holder or the Risk Retention Consultation Party) and the 17g-5 Information Provider (which shall promptly post such notice on the 17g-5 Information Provider’s Website in accordance with Section 3.13(c)) in writing of any modification, waiver or amendment (in each case, after it is finalized and executed) of any term of any Mortgage Loan or Companion Loan that is modified, waived or amended and the date thereof. With respect to any modification, waiver or amendment (in each case, after it is finalized and executed) for which it is responsible,

 -309-

the Master Servicer shall provide written notice of any such modification, waiver or amendment to the Trustee, the Certificate Administrator, the Special Servicer (and the Special Servicer shall forward such notice to the Directing Holder and the Risk Retention Consultation Party (in the case of the Directing Holder, only prior to the occurrence and continuance of a Consultation Termination Event and in the case of the Directing Holder or the Risk Retention Consultation Party, other than with respect to an Excluded Loan as to such party), the applicable Companion Holder, the related Mortgage Loan Seller (so long as such Mortgage Loan Seller is not a Master Servicer or Sub-Servicer of such Mortgage Loan or the Directing Holder or Risk Retention Consultation Party) and the 17g-5 Information Provider (which shall promptly post such notice on the 17g-5 Information Provider’s Website in accordance with Section 3.13(c)). The party responsible for delivering notice shall deliver to the Custodian with a copy to the Master Servicer (if such notice is being delivered by the Special Servicer) for deposit in the related Mortgage File, an original counterpart of the agreement relating to such modification, waiver or amendment, promptly (and in any event within ten (10) Business Days) following the execution thereof, with a copy to the applicable Companion Holder, if any. Following receipt of the Master Servicer’s or the Special Servicer’s, as the case may be, delivery of the aforesaid modification, waiver or amendment to the Certificate Administrator, the Certificate Administrator shall forward a copy thereof to each Holder of a Certificate (other than the Class Z or Class R Certificates) upon request. With respect to the processing of any modification, waiver or consent related to any Mortgagor incurring additional debt or mezzanine debt, the Special Servicer (if the Special Servicer processes such modification, waiver or consent pursuant to Section 3.18(a)) or the Master Servicer (if the Master Servicer processes such modification, waiver or consent pursuant to Section 3.18(a)) shall, on or before the later of (i) 3:00 p.m. on the related P&I Advance Date and (ii) five (5) Business Days immediately following the Master Servicer or the Special Servicer, as the case may be, obtaining actual knowledge of the incurrence of such additional debt or mezzanine debt, deliver notice of the Mortgagor’s incurrence of such debt, substantially in the form of Exhibit KK, to cts.sec.notifications@wellsfargo.com and an Additional Disclosure Notification in the form attached hereto as Exhibit EE.

In the event that either (i) the CREFC^® Investor Reporting Package is amended to include such information set forth above, in a manner reasonably acceptable to the Master Servicer, the Special Servicer and Certificate Administrator, as applicable, and the Master Servicer confirms with the Certificate Administrator that such amended CREFC^® Investor Reporting Package enables the Certificate Administrator to include such information on Form 10-D in a manner reasonably acceptable to the Certificate Administrator, or (ii) the Trust is no longer subject to the Exchange Act, the additional report in the form of Exhibit KK shall no longer be required hereunder. From time to time, the Master Servicer, the Special Servicer and Certificate Administrator may agree on a different delivery time and format for the information set forth in this paragraph.

(h)         Subject to the consent rights and processes set forth in Section 6.08 with respect to Major Decisions, the Master Servicer shall process all defeasance transactions, and shall be entitled to any defeasance fees paid relating thereto (provided, that for the avoidance of

doubt, any such defeasance fee shall not include the Special Servicer’s portion of any Modification Fees or waiver fees in connection with a defeasance that the Special Servicer is entitled to under this Agreement). Notwithstanding the foregoing, the Master Servicer shall not permit (or, with regard to any Non-Serviced Mortgage Loan, take any act in furtherance of) the substitution of any Mortgaged Property pursuant to the defeasance provisions of any Mortgage Loan or a Serviced Whole Loan unless such defeasance complies with Treasury Regulations Section 1.860G-2(a)(8)(ii) and the Master Servicer has received (i) replacement collateral consisting of government securities within the meaning of Treasury Regulations Section 1.860G-2(a)(8)(ii), which satisfies the requirements of the applicable Mortgage Loan documents, in an amount sufficient to make all scheduled payments under the related Mortgage Loan or the Trust Subordinate Companion Loan (or defeased portion thereof) when due, (ii) a certificate of an Independent certified public accountant to the effect that such substituted property will provide cash flows sufficient to meet all payments of interest and principal (including payments at maturity) on such Mortgage Loan or Serviced Whole Loan in compliance with the requirements of the terms of the related Mortgage Loan documents and, if applicable, Companion Loan documents, (iii) one or more Opinions of Counsel (at the expense of the related Mortgagor) to the effect that the Trustee, on behalf of the Trust, will have a first priority perfected security interest in such substituted Mortgaged Property; provided, however, that, to the extent consistent with the related Mortgage Loan documents and, if applicable, Companion Loan documents, the related Mortgagor shall pay the cost of any such opinion as a condition to granting such defeasance, (iv) to the extent consistent with the related Mortgage Loan documents and, if applicable, Companion Loan documents, the Mortgagor shall establish a single purpose entity to act as a successor mortgagor, if so required by the Rating Agencies, (v) to the extent permissible under the related Mortgage Loan documents and, if applicable, Companion Loan documents, the Master Servicer shall use its reasonable efforts to require the related Mortgagor to pay all costs of such defeasance, including but not limited to the cost of maintaining any successor mortgagor, and (vi) to the extent permissible under the Mortgage Loan documents and, if applicable, Companion Loan documents, the Master Servicer shall obtain, at the expense of the related Mortgagor, Rating Agency Confirmation from each Rating Agency and a confirmation of any applicable rating agencies that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings of any class of Serviced Companion Loan Securities (if any) (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant to Section 3.25); provided, further, however, that no such confirmation from any Rating Agency shall be required to the extent that the Master Servicer has delivered a defeasance certificate substantially in the form of Exhibit U hereto for any Mortgage Loan or Trust Subordinate Companion Loan that (together with any Mortgage Loans cross-collateralized with such Mortgage Loans) is: (i) a Mortgage Loan with a Cut-off Date Balance less than $20,000,000, (ii) a Mortgage Loan that represents less than 5% of the aggregate Cut-off Date Balance of all Mortgage Loans and (iii) a Mortgage Loan that is not one of the ten largest Mortgage Loans by Stated Principal Balance. Notwithstanding the foregoing, in the event that requiring the Mortgagor to pay for the items specified in clauses (ii), (iv) and (v) in the preceding sentence would be inconsistent with the related Mortgage Loan documents, such reasonable costs shall be paid by the related Mortgage Loan Seller as and to the extent set forth in the applicable Mortgage Loan Purchase Agreement.

(i)Notwithstanding anything herein or in the related Mortgage Loan documents and, if applicable, Companion Loan documents, to the contrary, the Master Servicer may permit the substitution of “government securities,” within the meaning of Section 2(a)(16) of the Investment Company Act of 1940, that comply with Treasury Regulations Section 1.860G-2(a)(8)(ii) for any Mortgaged Property pursuant to the defeasance provisions of any Mortgage Loan or a Serviced Whole Loan, as applicable (or any portion thereof), in lieu of the defeasance collateral specified in the related Mortgage Loan documents or Serviced Whole Loan documents, as applicable; provided that such substitution is consistent with the Servicing Standard and the Master Servicer (subject to the Special Servicer’s consent rights pursuant to Section 3.18(a) with respect to any such action that constitutes a Major Decision) reasonably determines that allowing their use would not cause a default or event of default to become reasonably foreseeable and the Master Servicer receives an Opinion of Counsel (at the expense of the Mortgagor to the extent permitted under the Mortgage Loan documents and, if applicable, Companion Loan documents or otherwise as a Trust Fund expense) to the effect that such use would not be and would not constitute a “significant modification” of such Mortgage Loan or Companion Loan pursuant to Treasury Regulations Section 1.860G-2(b) and would not otherwise constitute an Adverse REMIC Event with respect to any Trust REMIC; and provided, further, that the requirements set forth in Section 3.18(h) (including receipt of any Rating Agency Confirmation) are satisfied; and provided, further, that such securities are backed by the full faith and credit of the United States government, or the Master Servicer shall obtain Rating Agency Confirmation from each Rating Agency and a confirmation of any applicable rating agencies that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings of any class of Serviced Companion Loan Securities (if any) (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant to Section 3.25). Notwithstanding the foregoing, with respect to certain Mortgage Loans originated or acquired by BSP, BSPRT, Column or NREC that are subject to defeasance and identified on Schedule 3, BSP, BSPRT, Column or NREC, as applicable, has transferred to a third party or has retained on behalf of itself or its Affiliate the right to establish or designate the successor borrower and/or to purchase or cause to be purchased the related defeasance collateral (collectively, the “Loan Seller Defeasance Rights and Obligations”). In the event the Master Servicer receives notice of a defeasance request with respect to a Mortgage Loan that provides for Loan Seller Defeasance Rights and Obligations in the related Mortgage Loan Documents, the Master Servicer shall provide, within five (5) business days of receipt of such notice, written notice of such defeasance request to the related Mortgage Loan Seller. Until such time as the related Mortgage Loan Seller provides written notice to the contrary, notice of a defeasance of a Mortgage Loan with Loan Seller Defeasance Rights and Obligations shall be delivered to the related Mortgage Loan Seller, as applicable, pursuant to the notice provisions hereof. If the successor borrower is not designated or formed by BSP, BSPRT or Column, as the case may be, or any Affiliate or successor thereto, the successor borrower shall be reasonably acceptable to the Master Servicer in accordance with the Servicing Standard.

(j)If required under the related Mortgage Loan or Companion Loan documents or if otherwise consistent with the Servicing Standard, the Master Servicer shall establish and maintain one or more accounts (the “Defeasance Accounts”), which shall be Eligible Accounts, into which all payments received by the Master Servicer from any defeasance collateral substituted for any Mortgaged Property shall be deposited and retained, and shall

 -312-

administer such Defeasance Accounts in accordance with the Mortgage Loan or Companion Loan documents. Notwithstanding the foregoing, in no event shall the Master Servicer permit such amounts to be maintained in the Defeasance Account for a period in excess of ninety (90) days, unless such amounts are reinvested by the Master Servicer in “government securities,” within the meaning of Section 2(a)(16) of the Investment Company Act of 1940, that comply with Treasury Regulations Section 1.860G-2(a)(8)(ii). To the extent not required or permitted to be placed in a separate account, the Master Servicer shall deposit all payments received by it from defeasance collateral substituted for any Mortgaged Property into the Collection Account and treat any such payments as payments made on the Mortgage Loan or Companion Loan in advance of its Due Date in accordance with clause (a)(i) of the definition of “Pooled Available Funds”, clause (a)(i) of the definition of “Y&L Towers Trust Subordinate Companion Loan Available Funds” or clause (a)(i) of the definition of the “Standard Highline Trust Subordinate Companion Loan Available Funds”, as applicable and not as a prepayment of the related Mortgage Loan or Companion Loan. Notwithstanding anything herein to the contrary, in no event shall the Master Servicer permit such amounts to be maintained in the Collection Account for a period in excess of 365 days (or 366 days in the case of a leap year).

(k)Notwithstanding anything to the contrary in this Agreement, neither the Master Servicer nor the Special Servicer, as applicable, shall, unless it has received Rating Agency Confirmation from each Rating Agency and a confirmation of any applicable rating agencies that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings of any class of Serviced Companion Loan Securities (if any) (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant to Section 3.25) (the cost of which shall be paid by the related Mortgagor, if so allowed by the terms of the related loan documents and otherwise paid out of general collections) grant or accept any consent, approval or direction regarding the termination of the related property manager or the designation of any replacement property manager, with respect to any Mortgaged Property that secures a Mortgage Loan that (i) is one of the ten largest Mortgage Loans by Stated Principal Balance, (ii) has an unpaid principal balance that is at least equal to five percent (5%) of the then-aggregate principal balance of all Mortgage Loans or $35,000,000 or (iii) is the Yorkshire & Lexington Towers Whole Loan or The Standard Highline NYC Whole Loan.

(l)Notwithstanding anything to the contrary in this Agreement, in connection with any modification, waiver, consent or amendment in connection with any defeasance transaction contemplated in clause (v)(iii) in the definition of “Major Decision”, the Master Servicer or the Special Servicer, as applicable, shall not approve any such modification, waiver or amendment or consent thereto without first having received a copy of an Opinion of Counsel addressed to the Master Servicer and the Special Servicer that such modification, waiver, consent or amendment will not cause an Adverse REMIC Event.

Section 3.19Transfer of Servicing Between Master Servicer and Special Servicer; Recordkeeping; Asset Status Report. (a)  Upon determining that a Servicing Transfer Event has occurred with respect to any Mortgage Loan (other than any Non-Serviced Mortgage Loan) or Serviced Companion Loan, the Master Servicer or the Special Servicer, as the case may be, shall promptly give notice to the Master Servicer or the Special Servicer, as the case may be, the Operating Advisor and the Directing Holder (in the case of the Directing Holder, (i) prior to

 -313-

the occurrence and continuance of a Consultation Termination Event and (ii) other than with respect to any Excluded Loan as to such party) thereof, and the Master Servicer shall deliver the related Mortgage File and Servicing File to the Special Servicer and concurrently provide a copy of such Servicing File, exclusive of all Privileged Communications, to the Operating Advisor. The Master Servicer shall use its reasonable efforts to provide the Special Servicer with all information, documents and records (including records stored electronically on computer tapes, magnetic discs and the like) relating to such Mortgage Loan and, if applicable, the related Serviced Companion Loan, either in the Master Servicer’s possession or otherwise available to the Master Servicer without undue burden or expense, and reasonably requested by the Special Servicer to enable it to assume its functions hereunder with respect thereto. The Master Servicer shall use its reasonable efforts to comply with the preceding sentence within five (5) Business Days of the occurrence of each related Servicing Transfer Event (or, in the case of clauses (viii), (ix) or (x) of the definition of Servicing Transfer Event, within five (5) Business Days of receiving notice from the Special Servicer of such Servicing Transfer Event when the Special Servicer makes the determination) and in any event shall continue to act as Master Servicer and administrator of such Mortgage Loan and, if applicable, the related Serviced Companion Loan until the Special Servicer has commenced the servicing of such Mortgage Loan and, if applicable, the related Serviced Companion Loan. The Master Servicer shall deliver to the Trustee, the Certificate Administrator, the Operating Advisor, the Directing Holder (other than with respect to any Excluded Loan as to such party and with respect to the Directing Certificateholder, prior to the occurrence and continuance of a Consultation Termination Event), a copy of the notice of such Servicing Transfer Event provided by the Master Servicer to the Special Servicer, or by the Special Servicer to the Master Servicer, pursuant to this Section 3.19. Prior to the occurrence and continuance of a Consultation Termination Event, the Certificate Administrator shall deliver to each Controlling Class Certificateholder a copy of the notice of such Servicing Transfer Event provided by the Master Servicer pursuant to this Section 3.19.

Upon determining that a Specially Serviced Loan (other than an REO Loan) has become current and has remained current for three consecutive Periodic Payments (provided that (i) no additional Servicing Transfer Event is foreseeable in the reasonable judgment of the Special Servicer, and (ii) for such purposes taking into account any modification or amendment of such Mortgage Loan and, if applicable, the related Companion Loan), and that no other Servicing Transfer Event is continuing with respect thereto, the Special Servicer shall immediately give notice thereof to the Master Servicer, the Operating Advisor, the related Serviced Companion Noteholder (unless, with respect to the Y&L Towers Trust Subordinate Companion Loan, a Y&L Towers Trust Subordinate Companion Loan Control Termination Event has occurred or with respect to the Standard Highline Trust Subordinate Companion Loan a Standard Highline Trust Subordinate Companion Loan Control Termination Event has occurred) and the Directing Holder (other than with respect to any Excluded Loan as to such party and with respect to the Directing Certificateholder, prior to the occurrence and continuance of a Consultation Termination Event) and shall return the related Mortgage File and Servicing File to the Master Servicer (or copies thereof if copies only were delivered to the Special Servicer) and upon giving such notice, and returning such Mortgage File and Servicing File to the Master Servicer, the Special Servicer’s obligation to service such Corrected Loan shall terminate and the obligations of the Master Servicer to service and administer such Mortgage Loan and, if applicable, the related Companion Loan shall recommence.

 -314-

(b)In servicing any Specially Serviced Loans and Serviced Companion Loans, the Special Servicer will provide to the Custodian originals of documents included within the definition of “Mortgage File” for inclusion in the related Mortgage File to the extent within its possession (with a copy of each such original to the Master Servicer), and provide the Master Servicer with copies of any additional related Mortgage Loan or Serviced Companion Loan information including correspondence with the related Mortgagor.

(c)Notwithstanding the provisions of Section 3.12(c), the Master Servicer shall maintain ongoing payment records with respect to each of the applicable Specially Serviced Loans, Serviced Companion Loans and REO Properties (other than with respect to a Non-Serviced Mortgage Loan) and shall provide the Special Servicer with any information in its possession with respect to such records to enable the Special Servicer to perform its duties under this Agreement; provided that this statement shall not be construed to require the Master Servicer to produce any additional reports.

(d)No later than (i) sixty (60) days after a Servicing Transfer Event for a Mortgage Loan (other than a Non-Serviced Mortgage Loan) or a Trust Subordinate Companion Loan and, if applicable, any related Companion Loan (in the event any Serviced Whole Loan becomes a Specially Serviced Loan) and (ii) prior to taking action with respect to any Major Decision (or making a determination not to take action with respect to a Major Decision) with respect to a Specially Serviced Loan, the Special Servicer shall deliver in electronic format a report (the “Asset Status Report”) with respect to such Mortgage Loan and related Companion Loan and the related Mortgaged Property (the “Initial Delivery Date”) and will be required to prepare one or more additional Asset Status Reports with respect to any such Specially Serviced Loan subsequent to the issuance of a Final Asset Status Report to the extent that during the course of the resolution of such Specially Serviced Loan changes in strategy reflected in the initial Asset Status Report (or subsequent Final Asset Status Report) are necessary to reflect the then-current recommendation as to how the Specially Serviced Loan might be returned to performing status or otherwise liquidated in accordance with the Servicing Standard (each such report a “Subsequent Asset Status Report”). Each Asset Status Report shall be delivered in electronic form to the Master Servicer, the Directing Holder (but only with respect to any Mortgage Loan or Trust Subordinate Companion Loan other than an Excluded Loan as to such party and prior to the occurrence and continuance of a Consultation Termination Event), the Risk Retention Consultation Party (but only with respect to any Mortgage Loan other than an Excluded Loan as to such party and other than with respect to the Yorkshire & Lexington Towers Mortgage Loan or The Standard Highline NYC Mortgage Loan), the Operating Advisor (but other than with respect to an Excluded Loan, only after the occurrence and continuance of an Operating Advisor Consultation Event), and the 17g-5 Information Provider (which shall promptly post such report on the 17g-5 Information Provider’s Website in accordance with Section 3.13(c)) and, with respect to any related Serviced Companion Loan, to the extent the related Serviced Companion Loan has been included in an Other Securitization, to the master servicer of such Other Securitization into which the related Serviced Companion Loan has been sold or to the related Companion Holder. The Special Servicer shall notify the Operating Advisor of whether any Asset Status Report delivered to the Operating Advisor is a Final Asset Status Report, which notification may be satisfied by (i) delivery of an Asset Status Report that is either signed by the Directing Holder or that otherwise includes an indication that such Asset Status Report is deemed approved due to the passage of any required consent or consultation

 -315-

time period or (ii) such other method as reasonably agreed to by the Operating Advisor and the Special Servicer. Such Asset Status Report shall set forth the following information to the extent reasonably determinable based on the information that was delivered to the Special Servicer in connection with the transfer of servicing pursuant to the Servicing Transfer Event:

(i)a summary of the status of such Specially Serviced Loan and any negotiations with the related Mortgagor;

(ii)a discussion of the legal and environmental considerations reasonably known to the Special Servicer, consistent with the Servicing Standard, that are applicable to the exercise of remedies as aforesaid and to the enforcement of any related guaranties or other collateral for the related Specially Serviced Loan and whether outside legal counsel has been retained;

(iv)(A) the Special Servicer’s recommendations on how such Specially Serviced Loan might be returned to performing status (including the modification of a monetary term, and any workout, restructure or debt forgiveness) and returned to the Master Servicer for regular servicing or otherwise realized upon (including any proposed sale of a Defaulted Loan or REO Property), (B) a description of any such proposed or taken actions, and (C) the alternative courses of action that were or are being considered by the Special Servicer in connection with the proposed or taken actions;

(vii)the decision that the Special Servicer made, or intends or proposes to make, including a narrative analysis setting forth the Special Servicer’s rationale for its proposed decision, including its rejection of the alternatives;

(viii)an analysis of whether or not taking such proposed action is reasonably likely to produce a greater recovery on a present value basis than not taking such action, setting forth (x) the basis on which the Special Servicer made such determination and (y) the net present value calculation and all related assumptions;

(ix)the appraised value of the related Mortgaged Property (and a copy of the last obtained Appraisal of such Mortgaged Property) together with a description of any adjustments to the valuation of such Mortgaged Property made by the Special Servicer together with an explanation of those adjustments; and

 -316-

(x)such other information as the Special Servicer deems relevant in light of the Servicing Standard.

A summary of each Asset Status Report shall be provided to the Certificate Administrator and the Trustee.

If within ten (10) Business Days of receiving an Asset Status Report, the Directing Holder does not disapprove such Asset Status Report in writing or if the Special Servicer makes a determination, in accordance with the Servicing Standard that the disapproval by the Directing Holder (communicated to the Special Servicer within ten (10) Business Days) is not in the best interest of all the Certificateholders), the Special Servicer shall implement the recommended action as outlined in such Asset Status Report; provided, however, that the Special Servicer may not take any action that is contrary to applicable law, the Servicing Standard or the terms of the applicable Mortgage Loan documents. If, with respect to any Mortgage Loan or Trust Subordinate Companion Loan other than an Excluded Loan with respect to the Directing Holder or the Holder of the majority of the Controlling Class prior to the occurrence and continuance of any Control Termination Event, the Directing Holder disapproves such Asset Status Report within ten (10) Business Days of receipt and the Special Servicer has not made the affirmative determination described above, the Special Servicer shall revise such Asset Status Report and deliver a new Asset Status Report as soon as practicable, but in no event later than thirty (30) days after such disapproval, to the Master Servicer, the Directing Holder (prior to the occurrence and continuance of a Consultation Termination Event and other than if an Excluded Loan as to such party is involved), the Operating Advisor (but only after the occurrence and during the continuance of an Operating Advisor Consultation Event) and the 17g-5 Information Provider (which shall promptly post such report on the 17g-5 Information Provider’s Website in accordance with Section 3.13(c)) and, in the case of a Serviced Whole Loan, the related Serviced Companion Noteholder. With respect to any Mortgage Loan or Trust Subordinate Companion Loan other than an Excluded Loan with respect to the Directing Holder or the Holder of the majority of the Controlling Class, prior to the occurrence and continuance of any Control Termination Event, the Special Servicer shall revise such Asset Status Report as described above in this Section 3.19(d) until the Directing Holder shall fail to disapprove such revised Asset Status Report in writing within ten (10) Business Days of receiving such revised Asset Status Report or until the Special Servicer makes a determination, in accordance with the Servicing Standard, that the disapproval is not in the best interests of the Certificateholders; provided that, if the Directing Holder has not approved the Asset Status Report for a period of sixty (60) Business Days following the first submission of an Asset Status Report, the Special Servicer may act upon the most recently submitted form of Asset Status Report, if consistent with the Servicing Standard; provided, however, that such Asset Status Report does not, and is not intended to be, a substitute for the approvals that are specifically required pursuant to Section 6.08. The procedures described in this paragraph are collectively referred to as the “Directing Holder Approval Process”. The Special Servicer may, from time to time, modify any Asset Status Report it has previously delivered and implement such report; provided that such report shall have been prepared, reviewed and not rejected pursuant to the terms of this Section 3.19(d). Notwithstanding anything herein to the contrary, with respect to any Excluded Loan with respect to the Directing Holder or the Holder of the majority of the Controlling Class (regardless of whether an Operating Advisor Consultation Event has occurred and is continuing), the Special Servicer shall consult with the Operating Advisor, on a non-binding basis, in

 -317-

connection with an Asset Status Report for an Excluded Loan with respect to the Directing Holder or the Holder of the majority of the Controlling Class that includes a Major Decision that it is processing or for which its consent is required and consider alternative actions recommended by the Operating Advisor, in respect thereof, in accordance with the procedures set forth in Section 6.08 for consulting with the Operating Advisor.

No direction or disapproval of the Directing Holder hereunder or under a related Intercreditor Agreement or failure of the Directing Holder to consent to or approve (including any deemed consents or approvals) any request of the Special Servicer, shall (a) require or cause the Special Servicer to violate the terms of a Specially Serviced Loan, applicable law or any provision of this Agreement, including the Special Servicer’s obligation to act in accordance with the Servicing Standard and to maintain the REMIC status of each Trust REMIC and the grantor trust status of the Grantor Trust, (b) result in the imposition of a “prohibited transaction” or “prohibited contribution” tax under the REMIC Provisions, (c) expose the Master Servicer, the Special Servicer, the Depositor, the Operating Advisor, the Mortgage Loan Sellers, the Trust, the Trustee, the Certificate Administrator or their respective officers, directors, members, employees or agents to any claim, suit or liability or (d) materially expand the scope of the Special Servicer’s, Trustee’s or the Master Servicer’s responsibilities under this Agreement.

Prior to an Operating Advisor Consultation Event, the Special Servicer will be required to deliver each Final Asset Status Report to the Operating Advisor after the completion of the Directing Holder Approval Process.

During the continuance of an Operating Advisor Consultation Event, the Operating Advisor shall provide comments to the Special Servicer in respect of the applicable Asset Status Report, if any, within ten (10) Business Days following the later of (i) receipt of such Asset Status Report or (ii) receipt of such additional information reasonably requested by the Operating Advisor related thereto, and propose possible alternative courses of action to the extent it determines such alternatives to be in the best interest of the Certificateholders (including any Certificateholders that are holders of the Controlling Class Certificates), as a collective whole. The Special Servicer shall consider such alternative courses of action, if any, and any other feedback provided by the Operating Advisor (and for so long as no Consultation Termination Event is continuing, the Directing Holder) in connection with the Special Servicer’s preparation of any Asset Status Report that is provided while an Operating Advisor Consultation Event has occurred and is continuing. The Special Servicer may revise the Asset Status Report as it deems necessary to take into account any input and/or comments from the Operating Advisor (and for so long as no Consultation Termination Event is continuing, the Directing Holder), to the extent the Special Servicer determines that the Operating Advisor’s and/or Directing Holder’s input and/or recommendations are consistent with the Servicing Standard and in the best interest of the Certificateholders as a collective whole (or, with respect to a Serviced Whole Loan, the best interest of the Certificateholders and the holders of the related Companion Loan(s), as a collective whole (taking into account the pari passu or subordinate nature of each such Companion Loan)). Promptly upon determining whether or not to revise any Asset Status Report to take into account any input and/or comments from the Operating Advisor or the Directing Holder, the Special Servicer shall deliver to the Operating Advisor and the Directing Holder the revised Asset Status Report (until a Final Asset Status Report is issued). The

 -318-

procedures described in this paragraph are collectively referred to as the “ASR Consultation Process”.

After the occurrence and during the continuance of a Control Termination Event (and at any time with respect to any Excluded Loan with respect to such party or the Holder of the majority of the Controlling Class), the Directing Holder shall have no right to consent to any Asset Status Report under this Section 3.19. After the occurrence and during the continuance of a Control Termination Event but prior to the occurrence and continuance of a Consultation Termination Event, the Special Servicer shall send the Directing Holder (except with respect to any Excluded Loan as to such party), and, after the occurrence and during the continuance of an Operating Advisor Consultation Event, the Operating Advisor, the Asset Status Report and the Operating Advisor and the Directing Holder shall consult with the Special Servicer and propose alternative courses of action and provide other feedback in respect of any Asset Status Report. The Directing Holder (or, if the Directing Holder is the Directing Certificateholder, other than in its capacity as a Certificateholder) (in each case, after the occurrence and during the continuance of a Consultation Termination Event (and at any time with respect to any Excluded Loan as to such party)), shall have no right to receive any Asset Status Report or otherwise consult with the Special Servicer with respect to Asset Status Reports and the Special Servicer shall only be obligated to consult with the Operating Advisor with respect to any Asset Status Report as described above. The Special Servicer may choose to revise the Asset Status Report as it deems reasonably necessary in accordance with the Servicing Standard to take into account any input and/or recommendations of the Operating Advisor or the Directing Holder during the applicable periods described above, but is under no obligation to follow any particular recommendation of the Operating Advisor or the Directing Holder.

The Special Servicer shall implement the Final Asset Status Report; provided, however, that the Special Servicer may not take any action that is contrary to applicable law, the Servicing Standard or the terms of the applicable Mortgage Loan documents.

Notwithstanding anything to the contrary herein, the Directing Holder shall not have any consultation or approval rights with respect to an Asset Status Report that relates to an Excluded Loan.

Notwithstanding the foregoing, the Special Servicer shall not be permitted to follow any advice, direction or consultation provided by the Operating Advisor, any Serviced Companion Noteholder (or its representative) or the Directing Certificateholder that would require or cause the Special Servicer to violate any applicable law, be inconsistent with the Servicing Standard or any Intercreditor Agreement, require or cause the Special Servicer to violate provisions of this Agreement, require or cause the Special Servicer to violate the terms of any Intercreditor Agreement or any Mortgage Loan or Serviced Whole Loan, expose any Certificateholder or any party to this Agreement or their affiliates, officers, directors or agents to any claim, suit or liability, cause any Trust REMIC to fail to qualify as a REMIC for federal income tax purposes or result in the imposition of “prohibited transaction” or “prohibited contribution” tax under the REMIC Provisions, or materially expand the scope of the Special Servicer’s responsibilities under this Agreement or any Intercreditor Agreement.

With respect to any Mortgage Loan or Trust Subordinate Companion Loan other than an Excluded Loan with respect to the Directing Certificateholder or the Holder of the majority of the Controlling Class, if, prior to the occurrence and continuance of a Control Termination Event, within five (5) Business Days of receipt of such draft summary, the Directing Certificateholder approves of, or does not disapprove of such draft summary, then the Special Servicer shall deliver in electronic format such notice and summary of the Final Asset Status Report to the Certificate Administrator for posting on the Certificate Administrator’s Website pursuant to Section 3.13(b). If the Directing Certificateholder affirmatively disapproves of such summary in writing, then within two (2) Business Days of receipt of such disapproval, the Special Servicer shall revise the summary and deliver such new summary to the Directing Certificateholder until the Directing Certificateholder approves such draft summary; provided, however, that if the Directing Certificateholder has not approved of the draft summary of the Final Asset Status Report within twenty (20) Business Days of receipt of the initial draft summary of the Final Asset Status Report, then the most recent draft summary of the Final Asset Status Report delivered by the Special Servicer prior to such 20th Business Day shall be deemed to be the final summary of the Final Asset Status Report; provided, further, however, that if at any time the Special Servicer determines that any affirmative disapproval of such draft summary by the Directing Certificateholder is not in the best interest of all the Certificateholders pursuant to the Servicing Standard, the Special Servicer shall deliver in electronic format such notice and summary of the Final Asset Status Report to the Certificate Administrator for posting on the Certificate Administrator’s Website pursuant to Section 3.13(b) notwithstanding such disapproval.

 -321-

Any successor master servicer or special servicer, as applicable, hereunder shall, upon becoming successor master servicer or special servicer, as applicable, be assigned and may assume any Sub-Servicing Agreements from the predecessor Master Servicer or the Special Servicer, as applicable (subject to Section 3.20(g) hereof). In addition, each Sub-Servicing Agreement entered into by the Master Servicer may but need not provide that the obligations of the Sub-Servicer thereunder may terminate with respect to any Mortgage Loan or Trust Subordinate Companion Loan serviced thereunder at the time such Mortgage Loan or Trust Subordinate Companion Loan becomes a Specially Serviced Loan; provided, however, that the Sub-Servicing Agreement may provide (if the Sub-Servicing Agreement provides for Advances by the Sub-Servicer, although it need not so provide) that the Sub-Servicer will continue to make all Advances and calculations and prepare all reports required under the Sub-Servicing Agreement with respect to Specially Serviced Loans and continue to collect its Primary Servicing Fees as if no Servicing Transfer Event had occurred and with respect to REO Properties (and the related REO Loans) as if no REO Acquisition had occurred and to render such incidental services with respect to such Specially Serviced Loans and REO Properties as are specifically provided for in such Sub-Servicing Agreement. The Master Servicer or the Special Servicer, as applicable, shall deliver to the Trustee (i) copies of all Sub-Servicing Agreements entered into by it, in each case, promptly upon its execution and delivery of such documents and (ii) upon request of the Trustee, any amendments or modifications to such Sub-Servicing Agreements. References in this Agreement to actions taken or to be taken by the Master Servicer include actions taken or to be taken by a Sub-Servicer on behalf of the Master Servicer; and, in connection therewith, all amounts advanced by any Sub-Servicer (if the Sub-Servicing Agreement provides for Advances by the Sub-Servicer, although it need not so provide) to satisfy the obligations of the Master Servicer hereunder to make Advances shall be deemed to have been advanced by the Master Servicer out of its own funds and, accordingly, in such event, such Advances shall be recoverable by such Sub-Servicer in the same manner and out of the same funds as if such Sub-Servicer were the Master Servicer, and, for so long as they are outstanding, such Advances shall accrue interest in accordance with Section 3.03(d), such interest to be allocable between the Master Servicer and such Sub-Servicer as may be provided (if at all) pursuant to the terms of the Sub-Servicing Agreement. For purposes of this Agreement, the Master Servicer shall be deemed to have received any payment when a Sub-Servicer retained by it receives such payment. The Master Servicer or the Special

 -322-

Servicer, as applicable, shall notify the Master Servicer or the Special Servicer, as applicable, the Trustee and the Depositor (and the Special Servicer shall notify the Operating Advisor) in writing promptly of the appointment by it of any Sub-Servicer, except that the Master Servicer need not provide such notice as to the Initial Sub-Servicing Agreements.

(b)Each Sub-Servicer shall be authorized to transact business in the state or states in which the related Mortgaged Properties it is to service are situated, if and to the extent required by applicable law to the extent necessary to ensure the enforceability of the related Mortgage Loans or Trust Subordinate Companion Loans or the compliance with its obligations under the Sub-Servicing Agreement and the Master Servicer’s or the Special Servicer’s obligations, as applicable, under this Agreement.

(c)As part of its servicing activities hereunder, the Master Servicer or the Special Servicer, as applicable, for the benefit of the Trustee and the Certificateholders, shall (at no expense to the Trustee, the Certificateholders or the Trust) monitor the performance and enforce the obligations of each Sub-Servicer under the related Sub-Servicing Agreement, except that the Master Servicer shall be required only to use reasonable efforts to cause any Initial Sub-Servicer to comply with the requirements of Article XI hereof. Such enforcement, including, without limitation, the legal prosecution of claims, termination of Sub-Servicing Agreements in accordance with their respective terms and the pursuit of other appropriate remedies, shall be in such form and carried out to such an extent and at such time as is in accordance with the Servicing Standard. The Master Servicer or the Special Servicer, as applicable, shall have the right to remove a Sub-Servicer retained by it in accordance with the terms of the related Sub-Servicing Agreement.

(d)In the event the Trustee or its designee becomes successor master servicer and assumes the rights and obligations of the Master Servicer under any Sub-Servicing Agreement, the Master Servicer, at its expense, shall deliver to the assuming party all documents and records relating to such Sub-Servicing Agreement and the Mortgage Loans and, if applicable, the Companion Loans then being serviced thereunder and an accounting of amounts collected and held on behalf of it thereunder, and otherwise use reasonable efforts to effect the orderly and efficient transfer of the Sub-Servicing Agreement to the assuming party.

(e)Notwithstanding the provisions of any Sub-Servicing Agreement and this Section 3.20, except to the extent provided in Article XI with respect to the obligations of any Sub-Servicer that is an Initial Sub-Servicer, the Master Servicer or the Special Servicer, as applicable, shall remain obligated and responsible to the Trustee, the Master Servicer, the Special Servicer, holders of the Companion Loans serviced hereunder and the Certificateholders for the performance of its obligations and duties under this Agreement in accordance with the provisions hereof to the same extent and under the same terms and conditions as if it alone were servicing and administering the Mortgage Loans or Trust Subordinate Companion Loans for which it is responsible, and the Master Servicer or the Special Servicer, as applicable, shall pay the fees of any Sub-Servicer thereunder as and when due from its own funds. In no event shall the Trust bear any termination fee required to be paid to any Sub-Servicer as a result of such Sub-Servicer’s termination under any Sub-Servicing Agreement.

 -323-

(f)The Trustee, upon the request of the Master Servicer or the Special Servicer, as applicable, shall furnish to any Sub-Servicer any documents necessary or appropriate to enable such Sub-Servicer to carry out its servicing and administrative duties under any Sub-Servicing Agreement.

(g)Each Sub-Servicing Agreement shall provide that, in the event the Trustee or any other Person becomes successor master servicer, the Trustee or such successor master servicer shall have the right to terminate such Sub-Servicing Agreement with or without cause and without a fee. Notwithstanding the foregoing or any other contrary provision in this Agreement, the Trustee and any successor master servicer shall assume each Initial Sub-Servicing Agreement and (i) the Initial Sub-Servicer’s rights and obligations under the Initial Sub-Servicing Agreement shall expressly survive a termination of the Master Servicer’s servicing rights under this Agreement; provided that the Initial Sub-Servicing Agreement has not been terminated in accordance with its provisions; (ii) any successor master servicer, including, without limitation, the Trustee (if it assumes the servicing obligations of the Master Servicer) shall be deemed to automatically assume and agree to the then-current Initial Sub-Servicing Agreement without further action upon becoming the successor master servicer and (iii) this Agreement may not be modified in any manner which would increase the obligations or limit the rights of the Initial Sub-Servicer hereunder and/or under the Initial Sub-Servicing Agreement, without the prior written consent of the Initial Sub-Servicer (which consent shall not be unreasonably withheld).

(h)With respect to Mortgage Loans or Trust Subordinate Companion Loans subject to a Sub-Servicing Agreement with the Master Servicer, the Special Servicer shall, upon request (such request to be made reasonably in advance as appropriate to the circumstances surrounding such request) of the related Sub-Servicer, reasonably cooperate in delivering reports and information, including remittance information, and affording access to information to the related Sub-Servicer that would be required to be delivered or afforded, as the case may be, to the Master Servicer pursuant to the terms hereof.

(i)Notwithstanding any other provision of this Agreement, the Special Servicer shall not enter into any Sub-Servicing Agreement that provides for the performance by third parties of any or all of its obligations herein, without, prior to the occurrence and continuance of any Control Termination Event and other than with respect to any Mortgage Loan or Trust Subordinate Companion Loan that is an Excluded Loan with respect to the Directing Holder or, if the Directing Holder is the Directing Certificateholder, the Holder of the majority of the Controlling Class, the consent of the Directing Holder, except to the extent necessary for the Special Servicer to comply with applicable regulatory requirements.

Notwithstanding anything to the contrary herein, no Sub-Servicer shall be permitted under any Sub-Servicing Agreement to make material servicing decisions, such as loan modifications or determinations as to the manner or timing of enforcing remedies under the Mortgage Loan documents, as applicable, without the consent of the Master Servicer or the Special Servicer, as applicable.

On the Closing Date, the initial Directing Certificateholder shall deliver to the parties to this Agreement a certification substantially in the form of Exhibit P-1G to this

 -325-

(b)Once a Directing Certificateholder has been selected, each of the Master Servicer, the Special Servicer, the Depositor, the Trustee, the Certificate Administrator, the Operating Advisor and each other Certificateholder (or Certificate Owner, if applicable) shall be entitled to rely on such selection unless the Controlling Class Certificateholders entitled to appoint the Directing Certificateholder, by Certificate Balance, or such Directing Certificateholder shall have notified the Master Servicer, the Special Servicer, the Trustee, the Certificate Administrator, the Operating Advisor and each other Controlling Class Certificateholder, in writing, of the resignation of such Directing Certificateholder or the selection of a new Directing Certificateholder.

Additionally, once a Risk Retention Consultation Party has been selected, each of the Master Servicer, the Special Servicer, the Depositor, the Trustee, the Certificate Administrator, the Operating Advisor and each other Certificateholder (or Certificate Owner, if applicable) shall be entitled to rely on such selection unless the Holders of the VRR Interest entitled to appoint the Risk Retention Consultation Party, by Certificate Balance, or such Risk Retention Consultation Party shall have notified the Master Servicer, the Special Servicer, the Trustee, the Certificate Administrator, the Operating Advisor and each other Holder of the VRR Interest, in writing, of the selection of a new Risk Retention Consultation Party.

(d)In the event that no Directing Holder has been appointed or identified to the Master Servicer or the Special Servicer, as applicable, and the Master Servicer or the Special Servicer, as the case may be, has attempted to obtain such information from the Certificate Administrator and no such entity has been identified to the Master Servicer or the Special Servicer, as applicable, then until such time as the new Directing Holder is identified, the Master Servicer or the Special Servicer, as applicable, shall have no duty to consult with, provide notice to, or seek the approval or consent of any such Directing Holder as the case may be.

(e)Upon request, the Certificate Administrator shall deliver to the Depositor, Trustee, the Special Servicer, the Operating Advisor, the Master Servicer and, prior to the occurrence and continuance of a Consultation Termination Event, the Directing Certificateholder, a list of each Controlling Class Certificateholder (or each Certificate Owner of the Controlling Class, if applicable), including names and addresses. In addition to the foregoing, within five (5) Business Days of receiving notice of the selection of a new Directing Certificateholder or Risk Retention Consultation Party or the existence of a new Controlling Class Certificateholder, the Certificate Administrator shall notify the Trustee, the Operating Advisor, the Master Servicer and the Special Servicer. Notwithstanding the foregoing, (a) Eightfold Real Estate Capital, L.P. shall be the initial Directing Certificateholder and shall remain so until a successor is appointed pursuant to the terms of this Agreement or until a Consultation Termination Event occurs and is continuing, and (b) NREC shall be the initial Risk Retention Consultation Party and shall remain so until a successor is appointed pursuant to the terms of this Agreement or until a Consultation Termination Event occurs and is continuing.

Until it receives notice to the contrary, each of the Master Servicer, the Special Servicer, the Operating Advisor, the Certificate Administrator and the Trustee shall be entitled to rely on the preceding sentence with respect to the identity of the Directing Certificateholder and the Risk Retention Consultation Party.

(f)If to the extent the Certificate Administrator determines that a Class of Book-Entry Certificates is the Controlling Class, the Certificate Administrator shall notify the related Certificateholders of such Class (through the Depository) of the Class becoming the Controlling Class.

(g)Each Certificateholder acknowledges and agrees, by its acceptance of its Certificates, that: (i) the Directing Holder may have special relationships and interests that conflict with those of Holders of one or more Classes of Certificates; (ii) the Directing Holder may act solely in the interests of the Holders of the Controlling Class; (iii) the Directing Certificateholder does not have any liability or duties to the Holders of any Class of Certificates other than the Controlling Class; (iv) the Directing Holder may take actions that favor interests of the Holders of one or more Classes of Certificates, including, without limitation, the Controlling Class, over the interests of the Holders of one or more other Classes of Certificates;

 -327-

and (v) the Directing Holder shall have no liability whatsoever (other than to a Controlling Class Certificateholder, to the extent the Directing Certificateholder is the Directing Holder) for having so acted, and no Certificateholder may take any action whatsoever against the Directing Holder or any director, officer, employee, agent or principal of the Directing Holder for having so acted.

Each Certificateholder acknowledges and agrees, by its acceptance of its Certificates, that: (i) the Risk Retention Consultation Party may have special relationships and interests that conflict with those of Holders of one or more Classes of Certificates; (ii) the Risk Retention Consultation Party may act solely in the interests of the Holders of the VRR Interest, the Y&L Towers VRR Interest or the Standard Highline VRR Interest, as applicable; (iii) the Risk Retention Consultation Party does not have any liability or duties to the Holders of any Class of Certificates other than the VRR Interest, the Y&L Towers VRR Interest or the Standard Highline VRR Interest, as applicable; (iv) the Risk Retention Consultation Party may take actions that favor interests of the Holders of one or more Classes including the VRR Interest, the Y&L Towers VRR Interest or the Standard Highline VRR Interest, as applicable, over the interests of the Holders of one or more other Classes of Certificates; and (v) the Risk Retention Consultation Party shall have no liability whatsoever (other than to a Holder of an VRR Interest, the Y&L Towers VRR Interest or the Standard Highline VRR Interest, as applicable) for having so acted as set forth in clauses (i) through (iv) above, and no Certificateholder may take any action whatsoever against the Risk Retention Consultation Party or any director, officer, employee, agent or principal of the Risk Retention Consultation Party for having so acted.

(h)All requirements of the Master Servicer and the Special Servicer to provide notices, reports, statements or other information (including the access to information on a website) to the Directing Holder contained in this Agreement shall also apply to each Companion Holder with respect to information relating to the related Serviced Whole Loan, as applicable; provided, however, that neither the Master Servicer nor the Special Servicer shall provide information that comprises Privileged Information following the date upon which they receive notice that such Standard Highline Non-Trust Junior Subordinate Companion Loan, Standard Highline Non-Trust Senior Subordinate Companion Loan or Standard Highline Trust Subordinate Companion Loan is subject to a Standard Highline Non-Trust Junior Subordinate Companion Loan Control Termination Event, a Standard Highline Non-Trust Senior Companion Loan Control Termination Event or a Standard Highline Trust Subordinate Companion Loan Control Termination Event, as applicable, and thereafter the Master Servicer and the Special Servicer shall only be required to provide the Standard Highline Directing Holder with such information as is expressly required to be delivered pursuant to the Intercreditor Agreement; provided, however, that nothing in this subsection (h) shall in any way eliminate the obligation to deliver any information required to be delivered under the related Intercreditor Agreement.

(i)Until it receives notice to the contrary, each of the Master Servicer, the Special Servicer, the Certificate Administrator, the Trustee and the Operating Advisor shall be entitled to rely on the most recent notification with respect to the identity and contact information of the Controlling Class Certificateholder, the Directing Holder, the Risk Retention Consultation Party and any AB Whole Loan Controlling Holder.

 -328-

(j)With respect to a Serviced Whole Loan and any approval and consent rights in this Agreement with respect to such Serviced Whole Loan, the Directing Holder shall exercise such rights in accordance with the related Intercreditor Agreement.

(k)The Certificate Registrar shall determine which Class of Certificates is the then-current Controlling Class or provide the name, contact information and address of the then-current Directing Certificateholder within two (2) Business Days of a request from the Master Servicer, the Special Servicer, Certificate Administrator, Trustee, Operating Advisor or any Certificateholder and provide such information to the requesting party.

(l)At any time that the Controlling Class Certificateholder is the holder of a majority of the Class F Certificates and the Class F Certificates are the Controlling Class, it may waive its right (a) to appoint the Directing Certificateholder and (b) to exercise any of the Directing Certificateholder’s rights under this Agreement by irrevocable written notice delivered to the Depositor, the Certificate Administrator (which shall be via email to trustadministrationgroup@wellsfargo.com), the Trustee, the Master Servicer, the Special Servicer and the Operating Advisor. Notwithstanding anything to the contrary contained herein, during such time as a Control Termination Event or Consultation Termination Event is in existence solely as a result of the operation of clause (ii) of the definition of Control Termination Event and clause (ii) of the definition of Consultation Termination Event, such Control Termination Event or Consultation Termination Event shall be deemed to no longer be in existence and have not occurred with respect to any unaffiliated third party to whom the Controlling Class Certificateholder that irrevocably waived its right to exercise any of the rights of the Controlling Class Certificateholder has sold or transferred all or a portion of its interest in the Class F Certificates if such unaffiliated third party holds the majority of the Controlling Class after giving effect to such transfer (the “Non-Waiving Successor”). Following any such sale or transfer, the Non-Waiving Successor shall again have the rights of the Controlling Class Certificateholder as set forth herein (including the rights to appoint a Directing Certificateholder or cause the exercise of the rights of the Directing Certificateholder) without regard to any prior waiver by the predecessor Controlling Class Certificateholder. The Non-Waiving Successor shall also have the right to exercise any of the rights of the Controlling Class Certificateholder. No Non-Waiving Successor described above shall have any consent rights with respect to any Mortgage Loan or Trust Subordinate Companion Loan that became a Specially Serviced Loan prior to the sale or transfer of the Class F Certificates to the Non-Waiving Successor and had not also become a Corrected Loan prior to such sale or transfer until such time as such Mortgage Loan or Trust Subordinate Companion Loan becomes a Corrected Loan.

(m)Promptly upon its determination of a change in the Controlling Class, the Certificate Administrator shall (i) include on its statement made available pursuant to Section 4.02(a) of this Agreement the identity of the new Controlling Class and (ii) provide to the Master Servicer, the Special Servicer and the Operating Advisor notice of such event and the identity and contact information of the new Controlling Class Certificateholder (the cost of obtaining such information from DTC being an expense of the Trust). The Certificate Administrator shall notify the Operating Advisor, the Master Servicer and the Special Servicer within ten (10) Business Days of the existence or cessation of (i) any Control Termination Event, (ii) any Consultation Termination Event or (iii) any Operating Advisor Consultation Event.

 -329-

Upon the Certificate Administrator’s determination that a Control Termination Event, a Consultation Termination Event or an Operating Advisor Consultation Event has occurred or is terminated, the Certificate Administrator shall, within ten (10) Business Days, post a “special notice” on the Certificate Administrator’s Website pursuant to this provision.

In the event that a Control Termination Event has occurred due to a reduction of the Certificate Balance of the Class F Certificates (taking into account the application of any Cumulative Appraisal Reduction Amounts to notionally reduce the Certificate Balance of such Class in accordance with Section 4.05(a) hereof) to less than 25% of the Original Certificate Balance thereof, such special notice shall state “A Control Termination Event has occurred due to the reduction of the Certificate Balance of the Class F Certificates to less than 25% of the Original Certificate Balance thereof.”

In the event that a Control Termination Event or Consultation Termination Event has occurred due to the irrevocable waiver by a Class F Certificateholder who has become the Controlling Class Certificateholder of its right to appoint a Directing Certificateholder or to exercise any of the rights of the Controlling Class Certificateholder, such special notice shall state “A Control Termination Event and a Consultation Termination Event has occurred due to the irrevocable waiver by the Controlling Class Certificateholder of its rights as Controlling Class Certificateholder.”

In the event that a Consultation Termination Event has occurred due to the reduction of each Class of Control Eligible Corresponding Certificates below 25% of its Original Certificate Balance, in each case without regard to the application of any Cumulative Appraisal Reduction Amounts, such special notice shall state: “A Consultation Termination Event has occurred because no Class of Control Eligible Corresponding Certificates exists where such Class’s aggregate Certificate Balance is at least equal to 25% of the Original Certificate Balance of that Class, in each case without regard to the application of any Cumulative Appraisal Reduction Amounts.”

In the event of any transfer of a Class F Certificate, and upon notice to the Certificate Administrator in the form of Exhibit NN that results in a termination of a Control Termination Event or a Consultation Termination Event, such “special notice” shall state: “A Consultation Termination Event or a Control Termination Event has been terminated and is no longer in effect due to a transfer of a majority interest of the Controlling Class Certificates to an unaffiliated third party which has terminated any waiver by the prior Holder.”

The Directing Holder shall not have any consent or consultation rights with respect to any Mortgage Loan determined to be an Excluded Loan as to either the Directing Holder or, if the Directing Holder is the Directing Certificateholder, the Holder of the majority of the Controlling Class. Likewise, the Risk Retention Consultation Party shall not have any consultation rights with respect to any Mortgage Loan or Trust Subordinate Companion Loan, as applicable, determined to be an Excluded Loan as to either such Risk Retention Consultation Party or the Holder of the majority of the VRR Interest, the Y&L Towers VRR Interest or the Standard Highline VRR Interest, as applicable. In either such case, in respect of the servicing of any such Excluded Loan, a Control Termination Event and Consultation Termination Event will be deemed to have occurred with respect to such Excluded Loan.

(a)  Each of the Master Servicer and the Special Servicer acknowledges and agrees that each Serviced Whole Loan being serviced under this Agreement and each Mortgage Loan with mezzanine debt is subject to the terms and provisions of the related Intercreditor Agreement and each agrees to service each such Serviced Whole Loan and each Mortgage Loan with mezzanine debt in accordance with the related Intercreditor Agreement and this Agreement, including, without limitation, effecting distributions and allocating reimbursement of expenses in accordance with the related Intercreditor Agreement and, in the event of any conflict between the provisions of this Agreement and the related Intercreditor Agreement, the related Intercreditor Agreement shall govern.

Each of the Master Servicer and Special Servicer acknowledges and agrees that each Companion Holder and each mezzanine lender or its respective designee has the right to purchase the related Mortgage Loan pursuant to the terms and conditions of this Agreement and the related Intercreditor Agreement to the extent provided for therein. All parties hereto further acknowledge and agree that any AB Whole Loan Controlling Holder will have the right to replace the Special Servicer solely with respect to the related Pooled Serviced AB Whole Loan and shall be entitled to exercise all approval rights of the Directing Holder regarding any Asset Status Report in respect of the related Mortgage Loan or related REO Property, without regard to the occurrence of any Control Termination Event or Consultation Termination Event with respect to the related Pooled Serviced AB Whole Loan, to the extent provided for herein and in the related Intercreditor Agreement.

(b)Neither the Master Servicer nor the Special Servicer shall have any liability for any cost, claim or damage that arises from any entitlement in favor of a Companion Holder or a mezzanine lender under the related Intercreditor Agreement or conflict between the terms of this Agreement and the terms of such Intercreditor Agreement. Notwithstanding any provision of any Intercreditor Agreement that may otherwise require the Master Servicer or the Special Servicer to abide by any instruction or direction of a Companion Holder or a mezzanine lender, neither the Master Servicer nor the Special Servicer shall be required to comply with any instruction or direction the compliance with which requires an Advance that constitutes or would constitute a Nonrecoverable Advance. In no event shall any expense arising from compliance with an Intercreditor Agreement constitute an expense to be borne by the Master Servicer or the Special Servicer for its own account without reimbursement. In no event shall the Master Servicer or the Special Servicer be required to consult with or obtain the consent of any Companion Holder or a mezzanine lender unless such Companion Holder or mezzanine lender has delivered notice of its identity and contact information to each of the parties to this Agreement (upon which notice each of the parties to this Agreement shall be conclusively entitled to rely). As of the Closing Date, the contact information for the Companion Holders and mezzanine lenders is as set forth in the related Intercreditor Agreement. In no event shall the Master Servicer or the Special Servicer, as applicable, be required to consult with or obtain the consent of a new Directing Certificateholder or a new Controlling Class Certificateholder or consult with a new Risk Retention Consultation Party unless the Certificate Administrator has delivered notice to the Master Servicer or the Special Servicer, as applicable, as required under

Section 3.23(e) or the Master Servicer or the Special Servicer, as applicable, have actual knowledge of the identity and contact information of a new Directing Certificateholder, a new Controlling Class Certificateholder or a new Risk Retention Consultation Party.

(c)No direction or disapproval of the Companion Holders or any mezzanine lender shall (a) require or cause the Master Servicer or the Special Servicer to violate the terms of a Mortgage Loan or Serviced Companion Loan, applicable law or any provision of this Agreement, including the Master Servicer’s or the Special Servicer’s obligation to act in accordance with the Servicing Standard and to maintain the REMIC status of each Trust REMIC and the grantor trust status of the Grantor Trust, (b) result in the imposition of a “prohibited transaction” or “prohibited contribution” tax under the REMIC Provisions or (c) materially expand the scope of the Special Servicer’s, Trustee’s, the Certificate Administrator’s or the Master Servicer’s responsibilities under this Agreement.

(d)With respect to any Serviced Pari Passu Companion Loan, notwithstanding any rights the Operating Advisor, the Directing Certificateholder or the Risk Retention Consultation Party hereunder may have to consult with respect to any action or other matter with respect to the servicing of such Companion Loan, to the extent the related Intercreditor Agreement provides that such right is exercisable by the related Companion Holder or is exercisable in conjunction with any related Companion Holder, the Directing Certificateholder and the Risk Retention Consultation Party shall not be permitted to exercise such right or, to the extent provided in the related Intercreditor Agreement, shall be required to exercise such right in conjunction with the related Companion Holder, as applicable (except to the extent that the Directing Certificateholder or the Risk Retention Consultation Party is the related Serviced Whole Loan Controlling Holder). Additionally, notwithstanding anything in this Agreement to the contrary, the Master Servicer or the Special Servicer, as the case may be, shall consult, seek the approval or obtain the consent of the holder of any Serviced Companion Loan with respect to any matters with respect to the servicing of such Companion Loan to the extent required under related Intercreditor Agreement and shall not take such actions requiring consent of the related Companion Holder without such consent. In addition, notwithstanding anything to the contrary, the Master Servicer or the Special Servicer, as the case may be, shall deliver reports and notices to the related Companion Holder as required under the Intercreditor Agreement.

(e)Notwithstanding anything in this Agreement to the contrary, the Special Servicer shall be required (1) to provide copies of any notice, information and report that it is required to provide to the Controlling Class Certificateholder pursuant to this Agreement with respect to any Major Decisions or the implementation of any recommended actions outlined in an Asset Status Report relating to a Serviced Whole Loan, to the related Companion Holder, within the same time frame it is required to provide to the Controlling Class Certificateholder (for this purpose, without regard to whether such items are actually required to be provided to the Controlling Class Certificateholder under this Agreement due to the occurrence and continuance of a Control Termination Event or a Consultation Termination Event) and (2) to consult with any related Companion Holder on a strictly non-binding basis, to the extent having received such notices, information and reports, such related Companion Holder requests consultation with respect to any such Major Decisions or the implementation of any recommended actions outlined in an Asset Status Report relating to a Serviced Whole Loan, and consider alternative actions

 -332-

recommended by such related Companion Holder; provided that after the expiration of a period of ten (10) Business Days from the delivery to such related Companion Holder by the Special Servicer of written notice of a proposed action, together with copies of the notice, information and report required to be provided to the Controlling Class Certificateholder, the Special Servicer shall no longer be obligated to consult with such related Companion Holder, whether or not such related Companion Holder has responded within such ten (10) Business Day period (unless, the Special Servicer proposes a new course of action that is materially different from the action previously proposed, in which case such ten (10) Business Day period shall be deemed to begin anew from the date of such proposal and delivery of all information relating thereto). Notwithstanding the consultation rights of the related Companion Holder, the Master Servicer or Special Servicer, as applicable, may make any Major Decision or take any action set forth in the Asset Status Report before the expiration of the aforementioned ten (10) Business Day period if the Master Servicer or Special Servicer, as applicable, determines that immediate action with respect thereto is necessary to protect the interests of the Certificateholders and the related Companion Holder. In no event shall the Master Servicer or the Special Servicer, as applicable, be obligated at any time to follow or take any alternative actions recommended by the related Companion Holder.

(f)In addition to the consultation rights of the holder of a Serviced Pari Passu Companion Loan provided in the immediately preceding paragraph, such Companion Holder shall have the right to attend (in person or telephonically, in the discretion of the Master Servicer or Special Servicer, as the case may be) annual meetings with the Master Servicer or the Special Servicer at the offices of the Master Servicer or the Special Servicer, as applicable, upon reasonable notice and at times reasonably acceptable to the Master Servicer or the Special Servicer, as applicable, in which servicing issues related to the related Whole Loan are discussed.

(g)With respect to any Serviced Whole Loan, the Special Servicer shall not modify, waive or amend the terms of the related Intercreditor Agreement such that the monthly remittance to the holder of the related Companion Loan is required earlier than 2 Business Days after receipt by the Master Servicer of the related Periodic Payment without the consent of the Master Servicer.

(h)Any modification or amendment to an Intercreditor Agreement that would materially adversely affect the Master Servicer or the Special Servicer, as applicable, shall require the prior consent of the Master Servicer or the Special Servicer, as applicable.

(i)With respect to each Serviced Whole Loan, if any Serviced Companion Loan becomes the subject of an “asset review” (or such analogous term defined in the related Other Pooling and Servicing Agreement) pursuant to the related Other Pooling and Servicing Agreement, the Master Servicer, the Special Servicer, the Trustee and the Custodian shall reasonably cooperate with the asset representations reviewer under the Other Pooling and Servicing Agreement or any other party to the Other Pooling and Servicing Agreement in connection with such Asset Review by providing the asset representations reviewer under the Other Pooling and Servicing Agreement or such other requesting party with any documents reasonably requested by the asset representations reviewer under the Other Pooling and Servicing Agreement or such other requesting party, but only to the extent such documents are in

 -333-

the possession of the Master Servicer, the Special Servicer, the Trustee or the Custodian, as the case may be.

Section 3.25Rating Agency Confirmation. (a)  Notwithstanding the terms of any related Mortgage Loan documents or other provisions of this Agreement, if any action under any Mortgage Loan documents or this Agreement requires Rating Agency Confirmation as a condition precedent to such action, if the party (the “RAC Requesting Party”) required to obtain such Rating Agency Confirmation from each Rating Agency has made a request to any Rating Agency for such Rating Agency Confirmation and, within ten (10) Business Days of the Rating Agency Confirmation request being posted to the 17g-5 Information Provider’s Website, such Rating Agency has not replied to such request or has responded in a manner that indicates that such Rating Agency is neither reviewing such request nor waiving the requirement for Rating Agency Confirmation, then such RAC Requesting Party shall be required to confirm (through direct communication and not by posting any confirmation on the 17g-5 Information Provider’s Website) that the applicable Rating Agency has received the Rating Agency Confirmation request, and, if it has not, promptly request the related Rating Agency Confirmation again (which may also be through direct communication). The circumstances described in the preceding sentence are referred to in this Agreement as a “RAC No-Response Scenario.” Once the RAC Requesting Party has sent a request for a Rating Agency Confirmation to the 17g-5 Information Provider, such RAC Requesting Party, may, but shall not be obligated to send such request directly to the Rating Agencies in accordance with the procedures set forth in this Section 3.25.

If there is no response to such Rating Agency Confirmation request within five (5) Business Days of such second request in a RAC No-Response Scenario or if such Rating Agency has responded in a manner that indicates such Rating Agency is neither reviewing such request nor waiving the requirement for Rating Agency Confirmation, then (x) with respect to any condition in any Mortgage Loan document requiring such Rating Agency Confirmation or with respect to any other matter under this Agreement relating to the servicing of the Mortgage Loans and the Trust Subordinate Companion Loans (other than as set forth in clause (y) below), the requirement to obtain a Rating Agency Confirmation shall be deemed not to apply for such matter at such time (as if such requirement did not exist) with respect to such Rating Agency and the Master Servicer or the Special Servicer, as the case may be, may then take such action if the Master Servicer or the Special Servicer, as applicable, confirms its original determination (made prior to making such request) that taking the action with respect to which it requested the Rating Agency Confirmation would still be consistent with the Servicing Standard, and (y) with respect to a replacement of the Master Servicer or the Special Servicer, such condition shall be deemed not to apply (as if such requirement did not exist) if (i) the applicable replacement master servicer or special servicer, as applicable, it has been appointed and currently serves as a master servicer or special servicer is listed on S&P’s Select Servicer List as a U.S. Commercial Mortgage Master Servicer or U.S. Commercial Mortgage Special Servicer, as applicable, if S&P is the non-responding Rating Agency, (ii) the applicable replacement master servicer or special servicer is rated at least “CMS3” (in the case of the replacement master servicer) or “CSS3” (in the case of the replacement special servicer), if Fitch is the non-responding Rating Agency or (iii) KBRA has not cited servicing concerns with respect to the replacement master servicer or special servicer as the sole or a material factor in any qualification, downgrade or withdrawal of the ratings (or placement on “watch status” in contemplation of a ratings downgrade or withdrawal) of securities in any other commercial mortgage-backed securitization transaction

 -334-

serviced by such replacement master servicer or special servicer prior to the time of determination, if KBRA is the non-responding Rating Agency. In addition, with respect to the Yorkshire & Lexington Towers Whole Loan and The Standard Highline NYC Whole Loan, with respect to a replacement of the Master Servicer or the Special Servicer, such condition shall be deemed not to apply (as if such requirement did not exist) if the replacement master servicer or replacement special servicer is acting as master servicer or special servicer, as applicable, in a commercial mortgage loan securitization that was rated by a Rating Agency within the 12-month period prior to the date of determination and Morningstar has not qualified, downgraded or withdrawn the then-current rating or ratings of one or more classes of CMBS certificates citing servicing concerns with the replacement master servicer or replacement special servicer, as applicable, as the sole or material factor in such rating action, if Morningstar is the non-responding Rating Agency.

Any Rating Agency Confirmation request made by the Master Servicer, Special Servicer, Certificate Administrator or Trustee, as applicable, pursuant to this Agreement, shall be made in writing, which writing shall contain a cover page indicating the nature of the Rating Agency Confirmation request, and shall contain all back-up material necessary for the Rating Agency to process such request. Such written Rating Agency Confirmation request shall be provided in electronic format to the 17g-5 Information Provider, and the 17g-5 Information Provider shall post such request on the 17g-5 Information Provider’s Website in accordance with Section 3.13(c).

Promptly following the Master Servicer’s or the Special Servicer’s determination to take any action discussed in this Section 3.25(a) following any requirement to obtain a Rating Agency Confirmation being deemed not to apply (as if such requirement did not exist), the Master Servicer or the Special Servicer, as applicable, shall provide electronic written notice to the 17g-5 Information Provider of the action taken for the particular item at such time, and the 17g-5 Information Provider shall promptly post such notice on the 17g-5 Information Provider’s Website in accordance with Section 3.13(c).

(b)Notwithstanding anything to the contrary in this Section 3.25, for purposes of the provisions of any Mortgage Loan document relating to defeasance (including without limitation the type of collateral acceptable for use as defeasance collateral) or release or substitution of any collateral, any Rating Agency Confirmation requirement in the Mortgage Loan documents for which the Master Servicer or the Special Servicer would have been permitted to waive obtaining such Rating Agency Confirmation pursuant to Section 3.25(a) shall be deemed not to apply (as if such requirement did not exist).

(c)For all other matters or actions not specifically discussed in Section 3.25(a) above, the applicable RAC Requesting Party shall deliver Rating Agency Confirmation from each Rating Agency.

Section 3.26The Operating Advisor. (a)  The Operating Advisor shall promptly review (i) the actions of the Special Servicer with respect to a Mortgage Loan or Trust Subordinate Companion Loan when it is a Specially Serviced Loan (as provided in Section 3.19(d), Section 3.26 and Section 6.08) and after the occurrence and during the continuance of an Operating Advisor Consultation Event the actions of the Special Servicer with

 -335-

respect to Major Decisions relating to the Mortgage Loans or Trust Subordinate Companion Loans when they are not a Specially Serviced Loan when a Major Decision Reporting Package has been delivered, (ii) all reports by the Special Servicer made available to Privileged Persons on the Certificate Administrator’s Website; and (iii) each Asset Status Report (after the occurrence and during the continuance of an Operating Advisor Consultation Event) and each Final Asset Status Report delivered to the Operating Advisor by the Special Servicer. The Operating Advisor shall perform its duties hereunder in accordance with the Operating Advisor Standard. In addition and for the avoidance of doubt, although the Operating Advisor may have certain consultation duties with the Master Servicer with respect to certain Major Decisions processed by the Master Servicer, the Operating Advisor will have no obligations or responsibility at any time to review or assess the actions of the Master Servicer for compliance with the Servicing Standard, and the Operating Advisor will not be required to consider such Master Servicer actions in connection with any Operating Advisor Annual Report.

(b)The Operating Advisor and its Affiliates will be obligated to keep confidential any information appropriately labeled as “Privileged Information” received from the Special Servicer or Directing Holder in connection with the Directing Holder’s exercise of its rights under this Agreement (including, without limitation, in connection with the review and/or approval of any Asset Status Report) or otherwise in connection with this transaction, except under the circumstances described in Section 3.26(f) and subject to any Privileged Information Exception or law, rule, regulation, order, judgment or decree requiring the disclosure of such labeled Privileged Information. Subject to the terms and conditions in this Agreement related to Privileged Information, the Operating Advisor agrees that it shall use information received from the Special Servicer pursuant to the terms of this Agreement solely for purposes of complying with its duties and obligations hereunder.

(c)(i)  Based on the Operating Advisor’s review of any assessment of compliance report, any attestation report, any Major Decision Reporting Package, and/or Asset Status Report (in the case of a Major Decision Reporting Package or Asset Status Report, after the occurrence and during the continuance of an Operating Advisor Consultation Event), any Final Asset Status Report and other reports by the Special Servicer made available to Privileged Persons that are posted on the Certificate Administrator’s Website during the prior calendar year, the Operating Advisor shall (if, at any time during the prior calendar year, (i) any Mortgage Loan (other than a Non-Serviced Mortgage Loan) or Trust Subordinate Companion Loan was a Specially Serviced Loan or (ii) the Operating Advisor was entitled to consult with the Special Servicer with respect to any Major Decision during the prior calendar year) deliver to the Depositor, the Certificate Administrator (who shall promptly post such report on the Certificate Administrator’s Website in accordance with Section 3.13(b)) and the 17g-5 Information Provider (who shall post it to the 17g-5 Information Provider’s Website in accordance with Section 3.13(c)) within one hundred twenty (120) days of the end of the prior calendar year, an annual report (the “Operating Advisor Annual Report”), substantially in the form of Exhibit V (which form may be modified or altered as to either its organization or content by the Operating Advisor, subject to compliance of such form with the terms and provisions of this Agreement including, without limitation, provisions herein relating to Privileged Information; provided, however, that in no event shall the information or any other content included in the Operating Advisor Annual Report contravene any provision of this Agreement), that (a) sets forth whether the Operating Advisor believes, in its sole discretion exercised in good faith, that the Special

 -336-

Servicer is operating in compliance with the Servicing Standard with respect to its performance of its duties under this Agreement with respect to Specially Serviced Loans (and, after the occurrence and during the continuance of an Operating Advisor Consultation Event, with respect to Major Decisions on non-Specially Serviced Loans) during the prior calendar year on a “asset-level basis”, and (b) identifies (1) which, if any, standards the Operating Advisor believes, in its sole discretion exercised in good faith, the Special Servicer has failed to comply and (2) any deviations from the Special Servicer’s obligations under this Agreement with respect to the resolution or liquidation of any Specially Serviced Loan or REO Property (other than with respect to any REO Property related to any Non-Serviced Mortgage Loan); provided, however, that in the event the Special Servicer is replaced, the Operating Advisor Annual Report shall only relate to the Special Servicer that was acting as Special Servicer as of December 31 in the prior calendar year and is continuing in such capacity through the date of such Operating Advisor Annual Report. In preparing any Operating Advisor Annual Report, the Operating Advisor shall not be required to report on instances of non-compliance with, or deviations from, the Servicing Standard or the Special Servicer’s obligations under this Agreement that the Operating Advisor determines, in its sole discretion exercised in good faith, to be immaterial. As used in connection with the Operating Advisor Annual Report, the term “asset-level basis” refers to the Special Servicer’s performance of its duties with respect to the pool of Specially Serviced Loans (and, after the occurrence and continuance of an Operating Advisor Consultation Event, with respect to Major Decisions on non-Specially Serviced Loans) under this Agreement taking into account the Special Servicer’s specific duties under this Agreement as well as the extent to which those duties were performed in accordance with the Servicing Standard, with reasonable consideration by the Operating Advisor of any Assessment of Compliance Report, Attestation Report, Major Decision Reporting Package, Asset Status Report (after the occurrence and during the continuance of an Operating Advisor Consultation Event), Final Asset Status Report and other information, in each case, delivered to the Operating Advisor by the Special Servicer (other than any communications between the Directing Holder and the Special Servicer that would be Privileged Information) pursuant to this Agreement. Subject to the restrictions in this Agreement, including, without limitation, Section 3.26(f) hereof, each such Operating Advisor Annual Report shall comply with all of the confidentiality requirements described in this Agreement regarding Privileged Information (subject to any permitted exceptions). Such Operating Advisor Annual Report shall be delivered to the Depositor, the Certificate Administrator (which shall promptly post such Operating Advisor Annual Report on the Certificate Administrator’s Website in accordance with Section 3.13(b)) and the 17g-5 Information Provider (which shall promptly post such Operating Advisor Annual Report on the 17g-5 Information Provider’s Website in accordance with Section 3.13(c)); provided, however, that the Special Servicer shall be given an opportunity to review the Operating Advisor Annual Report at least five (5) Business Days prior to its delivery to the Depositor, the Certificate Administrator and the 17g-5 Information Provider. The Operating Advisor shall have no obligation to adopt any comments to the Operating Advisor Annual Report that are provided by the Special Servicer.

(ii)In the event the Operating Advisor’s ability to perform its obligations in respect of the Operating Advisor Annual Report is limited or prohibited due to the failure of a party hereto to timely deliver notice of action and information required to be delivered to the Operating Advisor or because such information is inaccurate or incomplete, the Operating Advisor shall set forth such limitations or prohibitions in the related Operating Advisor Annual Report and the Operating Advisor shall not be subject to any liability

 -337-

arising from such limitations or prohibitions. The Operating Advisor shall be entitled to rely on the accuracy and completeness of any information it is provided without liability for any such reliance hereunder.

(iii)The ability to perform the duties of the Operating Advisor and the quality and the depth of any Operating Advisor Annual Report shall be dependent upon the timely receipt of information prepared or made available by others and the accuracy and the completeness of such information. In addition, in no event will the Operating Advisor have the power to compel any transaction party to take, or refrain from taking, any action. The Operating Advisor shall be entitled to conclusively rely on the accuracy and completeness of any information it is provided without liability for any such reliance thereunder.

(iv)In the event a lack of access to Privileged Information limits or prohibits the Operating Advisor from performing its duties under this Agreement, the Operating Advisor shall set forth any such limitations or prohibitions known to the Operating Advisor in the related Operating Advisor Annual Report, and the Operating Advisor shall not be subject to any liability arising from such limitations or prohibitions.

(d)(i)  After the calculation has been finalized (and if an Operating Advisor Consultation Event has occurred and is continuing prior to the utilization) by the Special Servicer of any of the calculations related to (A) Appraisal Reduction Amounts, (B) Collateral Deficiency Amounts or (C) net present value in accordance with Section 1.02(iv), the Special Servicer shall forward such calculations, together with any supporting material or additional information necessary in support thereof (including such additional information reasonably requested by the Operating Advisor to confirm the mathematical accuracy of such calculations, but not including any Privileged Communications and, in the case of any Appraisal Reduction Amount or Collateral Deficiency Amount, only to the extent the Master Servicer has provided such information to the Special Servicer), to the Operating Advisor promptly, but in any event no later than two (2) Business Days after preparing such calculations, and the Operating Advisor shall promptly, but no later than three (3) Business Days after receipt of such calculations and any supporting or additional materials recalculate the accuracy of the mathematical calculations and the corresponding application of the non-discretionary portion of the applicable formulas required to be utilized in connection with any such calculation.

(ii)In connection with this Section 3.26(d), in the event the Operating Advisor does not agree with the mathematical calculations of the net present value, Appraisal Reduction Amount or Collateral Deficiency Amount (as calculated by the Special Servicer) or the application of the applicable non-discretionary portions of the formula required to be utilized for such calculation, the Operating Advisor and the Special Servicer shall consult with each other in order to resolve any material inaccuracy in the mathematical calculations or the application of the non-discretionary portions of the related formula in arriving at those mathematical calculations or any disagreement within five (5) Business Days of delivery of such calculations to the Operating Advisor. The Master Servicer shall cooperate with the Special Servicer and provide any information reasonably requested by the Special Servicer necessary for the calculation of the Appraisal Reduction Amount that is in the Master Servicer’s possession or reasonably obtainable by

 -338-

the Master Servicer. In the event the Operating Advisor and the Special Servicer are not able to resolve such inaccuracies or disagreement prior to the end of such five (5) Business Day period, the Operating Advisor shall promptly notify the Certificate Administrator of such disagreement and the Certificate Administrator shall examine the calculations and supporting materials provided by the Operating Advisor and the Special Servicer and determine which calculation is to apply (and shall provide notice of such determination to the Operating Advisor and the Special Servicer). In making such determination, the Certificate Administrator may hire an independent third party to assist with any such calculation at the expense of the Trust. The Certificate Administrator shall be entitled to conclusively rely on such third party calculation.

(e)Notwithstanding the foregoing, prior to the occurrence and continuance of an Operating Advisor Consultation Event, the Operating Advisor’s review will be limited to an after-the-action review of the reports and material described above (together with any additional information and material reviewed by the Operating Advisor) and, it shall have no involvement with respect to collateral substitutions, assignments, workouts, modifications, consents, waivers, insurance policies, mortgagor substitutions, lease changes or other similar actions that the Special Servicer may perform under this Agreement and will have no obligations at any time with respect to any Non-Serviced Mortgage Loan. In addition, with respect to the Operating Advisor’s review of net present value calculations as described above, the Operating Advisor’s recalculation will not take into account the reasonableness of Special Servicer’s property and borrower performance assumptions or other similar discretionary portions of the net present value calculation.

(f)The Operating Advisor and its Affiliates shall keep all information appropriately labeled as “Privileged Information” confidential and shall not, without the prior written consent of the Special Servicer and (for so long as no Consultation Termination Event is continuing) the Directing Holder (with respect to any Mortgage Loan or Trust Subordinate Companion Loan other than a Non-Serviced Whole Loan and any applicable Excluded Loan), disclose such information to any other Person (including any Certificateholders which are not then included in the Control Eligible Regular Interests, other than the Directing Certificateholder and the Risk Retention Consultation Party), other than (i) to the extent expressly set forth herein, to the other parties to this Agreement with a notice indicating that such information is Privileged Information, (ii) pursuant to a Privileged Information Exception or (iii) where necessary to support specific findings or conclusions concerning allegations of deviations from the Servicing Standard (A) in the Operating Advisor Annual Report or (B) in connection with a recommendation by the Operating Advisor to replace the Special Servicer. Each party to this Agreement that receives “Privileged Information” from the Operating Advisor with a notice stating that such information is Privileged Information shall not disclose such Privileged Information to any Person without the prior written consent of the Special Servicer and, unless a Control Termination Event has occurred, the Directing Certificateholder (with respect to any Mortgage Loan other than a Non-Serviced Whole Loan and other than an Excluded Loan) other than pursuant to a Privileged Information Exception. In addition and for the avoidance of doubt, while the Operating Advisor may serve in a similar capacity with respect to Other Securitizations that involve the same parties or borrower involved in this securitization, the knowledge of the Operating Advisor gained from performing operating advisor functions for such Other Securitizations are not imputed to the Operating Advisor performing the obligations hereunder.

 -339-

Notwithstanding the foregoing, the Operating Advisor shall be permitted to share Privileged Information with its Affiliates and any subcontractors of the Operating Advisor that agree in writing to be bound by the same confidentiality provisions applicable to the Operating Advisor.

(g)Subject to the requirements of confidentiality imposed on the Operating Advisor herein (including without limitation in respect of Privileged Information), the Operating Advisor shall respond to Inquiries proposed by Privileged Persons from time to time in accordance with the terms of Section 4.07(a).

(h)As compensation for its activities hereunder, the Operating Advisor shall be entitled to receive the Operating Advisor Fee on each Distribution Date with respect to each Mortgage Loan, Trust Subordinate Companion Loan or REO Mortgage Loan. As to each Mortgage Loan, each REO Loan and each Trust Subordinate Companion Loan, the Operating Advisor Fee shall accrue from time to time at the Operating Advisor Fee Rate and shall be computed on the basis of the Stated Principal Balance of such Mortgage Loan, REO Mortgage Loan or Trust Subordinate Companion Loan, as the case may be, and in the same manner as interest is calculated on the related Mortgage Loan, REO Mortgage Loan or Trust Subordinate Companion Loan, as the case may be, and, in connection with any partial month interest payment, for the same period respecting which any related interest payment due on the related Mortgage Loan or Trust Subordinate Companion Loan or deemed to be due on such REO Mortgage Loan is computed. The Operating Advisor Fee shall be payable from funds on deposit in the Collection Account as provided in Section 3.05(a)(ii) of this Agreement.

The Operating Advisor shall be entitled to reimbursement of any Operating Advisor Expenses provided for pursuant to Section 6.04(a) and/or 6.04(b) hereof, such amounts to be reimbursed from amounts on deposit in the Collection Account as provided by Section 3.05(a). Each successor Operating Advisor shall be required to acknowledge and agree to the terms of the preceding sentence.

In addition, the Operating Advisor Consulting Fee shall be payable to the Operating Advisor with respect to each Major Decision for which the Operating Advisor has consultation obligations hereunder. The Operating Advisor Consulting Fee shall be payable from funds on deposit in the Collection Account as provided in Section 3.05(a)(ii) of this Agreement, but, with respect to the period when the outstanding Certificate Balances of the Control Eligible Certificates have not been reduced to zero as a result of the allocation of Realized Losses to such Certificates, only to the extent such Operating Advisor Consulting Fee is actually received from the related Mortgagor; provided, however, that to the extent such Operating Advisor Consulting Fee is incurred after the outstanding Certificate Balances of the Control Eligible Regular Interests have been reduced to zero as a result of the allocation of Realized Losses to such Certificates, such Operating Advisor Consulting Fee shall be payable in full to the Operating Advisor as a Trust Fund expense. When the Operating Advisor has consultation obligations with respect to a Major Decision under this Agreement, the Master Servicer or the Special Servicer, as the case may be, shall use commercially reasonable efforts to collect the applicable Operating Advisor Consulting Fee from the related Mortgagor in connection with such Major Decision that are consistent with the efforts that the Master Servicer

 -340-

or the Special Servicer processing the Major Decision would use to collect any Mortgagor-paid fees owed to it in accordance with the Servicing Standard, but only to the extent not prohibited by the related Mortgage Loan documents. The Master Servicer or Special Servicer, as the case may be, may waive or reduce the amount of any Operating Advisor Consulting Fee payable by the related Mortgagor if it determines that such full or partial waiver is in accordance with the Servicing Standard, but in no event shall the Master Servicer or the Special Servicer take any enforcement action with respect to the collection of such Operating Advisor Consulting Fee other than requests for collection; provided that the Master Servicer or the Special Servicer, as applicable, shall consult, on a non-binding basis, with the Operating Advisor prior to any such waiver or reduction. Notwithstanding the foregoing, the Operating Advisor will have no obligations or consultation rights as Operating Advisor with respect to: (i) any Non-Serviced Whole Loan or any related REO Property or (ii) with respect to any Serviced AB Whole Loan, prior to the occurrence and continuance of an AB Control Appraisal Period; provided, further, that the Operating Advisor shall not be entitled to an Operating Advisor Consulting Fee with respect to any Non-Serviced Whole Loan.

(i)After the occurrence and during the continuance of a Consultation Termination Event, the Operating Advisor may be removed upon (i) the written direction of Certificateholders evidencing not less than 25% of the Voting Rights (taking into account the application of Appraisal Reduction Amounts to notionally reduce the Certificate Balances of Classes to which such Appraisal Reduction Amounts are allocable) requesting a vote to replace the Operating Advisor with a replacement Operating Advisor selected by such Certificateholders (provided that the proposed replacement Operating Advisor is an Eligible Operating Advisor), and (ii) payment by such requesting Holders to the Certificate Administrator of all reasonable fees and expenses to be incurred by the Certificate Administrator in connection with administering such vote. The Certificate Administrator shall promptly provide written notice to all applicable Certificateholders of such request by posting such notice on the Certificate Administrator’s Website in accordance with Section 3.13(b), and concurrently by mail, and conduct the solicitation of votes of all applicable Certificates in such regard. Upon the vote or written direction of Holders of at least 75% of the Voting Rights (taking into account the application of Appraisal Reduction Amounts to notionally reduce the Certificate Balances of Classes to which such Appraisal Reduction Amounts are allocable), the Trustee shall immediately replace the Operating Advisor with the replacement operating advisor.

(j)After the occurrence of an Operating Advisor Termination Event, the Trustee may, and upon the written direction of Certificateholders representing at least 25% of the Voting Rights (taking into account the application of any Appraisal Reduction Amounts to notionally reduce the Certificate Balance of the Classes of Certificates), the Trustee shall promptly terminate the Operating Advisor for cause and appoint a replacement operating advisor that is an Eligible Operating Advisor; provided that no such termination shall be effective until a successor operating advisor has been appointed and has assumed all of the obligations of the Operating Advisor under this Agreement; provided, further, that no such termination shall terminate the rights of the Operating Advisor that accrued prior to such termination, including accrued and unpaid compensation and indemnification rights. The Trustee may rely on a certification by the replacement operating advisor that it is an Eligible Operating Advisor. If the Trustee is unable to find a replacement operating advisor that is an Eligible Operating Advisor within thirty (30) days of the termination of the Operating Advisor, the Depositor shall be

 -341-

permitted to find a replacement. Upon any termination of the Operating Advisor and appointment of a successor to the Operating Advisor, the Trustee will, as soon as possible, be required to give written notice of the termination and appointment to the Special Servicer, the Master Servicer, the Certificate Administrator, the 17g-5 Information Provider (for posting to the 17g-5 Information Provider’s Website), the Depositor, the Directing Certificateholder (only for so long as no Consultation Termination Event has occurred and is continuing), the Risk Retention Consultation Party, any Companion Holder and the Certificateholders.

(k)The holders of Certificates representing at least 25% of the Voting Rights affected by any Operating Advisor Termination Event hereunder may waive such Operating Advisor Termination Event within twenty (20) days of the receipt of notice from the Certificate Administrator of the occurrence of such Operating Advisor Termination Event. Upon any such waiver of an Operating Advisor Termination Event, such Operating Advisor Termination Event shall cease to exist and shall be deemed to have been remedied for every purpose hereunder. Upon any such waiver of an Operating Advisor Termination Event by Certificateholders, the Trustee and the Certificate Administrator will be entitled to recover all costs and expenses incurred by it in connection with enforcement action taken with respect to such Operating Advisor Termination Event prior to such waiver from the Trust.

(l)Prior to the occurrence and continuance of a Control Termination Event, the Directing Certificateholder shall have the right to consent, such consent not to be unreasonably withheld, conditioned or delayed, to the identity of any replacement Operating Advisor appointed pursuant to this Section 3.26; provided, further, that such consent will be deemed to have been granted if no objection is made within ten (10) Business Days following the Directing Certificateholder’s receipt of the request for consent and, if granted or deemed granted, such consent cannot thereafter be revoked or withdrawn.

 -378-

Loan, REO Loan or Trust Subordinate Companion Loan during the related Collection Period, in each case net of any Liquidation Fees payable therefrom, shall be distributable as follows: if, during any particular Collection Period, any Yield Maintenance Charge is collected and allocable with respect to any Mortgage Loan, then on the Distribution Date corresponding to that Collection Period, the Certificate Administrator shall pay that Yield Maintenance Charge in the following manner: (a) pro rata, between (i) the group (the “YM Group A”) of Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class X-A and Class A-S Regular Interests, and (ii) the group (the “YM Group B” and collectively with the YM Group A, the “YM Groups”) of Class X-B, Class B, Class C and Class D Regular Interests, based upon the aggregate amount of principal distributed to the Classes of Pooled Regular Interests in each YM Group on such Distribution Date; and (b) as among the respective Classes of Pooled Regular Interests in each YM Group in the following manner: (1) on a pro rata basis in accordance with their respective entitlements in those Yield Maintenance Charges, to each Class of Pooled Regular Interests (other than Class X Regular Interests) in such YM Group in an amount equal to the product of (x) a fraction whose numerator is the amount of principal distributed to such Regular Interests on such Distribution Date and whose denominator is the total amount of principal distributed to all of the Pooled Regular Interests (other than Class X Regular Interests) in such YM Group on such Distribution Date, (y) the Base Interest Fraction for the related principal prepayment with respect to such Class of Pooled Regular Interests, and (z) the aggregate amount of such Yield Maintenance Charge allocated to such YM Group and (2) the portion of such Yield Maintenance Charge allocated to such YM Group remaining after such distributions to the applicable Class(es) of Pooled Regular Interests in such YM Group, in the case of amounts distributable to YM Group A, to the Class X-A Regular Interest and in the case of amounts distributable to YM Group B, to the Class X-B Regular Interest. Any Yield Maintenance Charges received and allocable with respect to a Trust Subordinate Companion Loan shall be distributed to the related Loan-Specific Regular Interests.

For purposes of the first paragraph of this Section 4.01(i), the relevant “Base Interest Fraction” in connection with any Principal Prepayment of any Mortgage Loan that provides for the payment of a Yield Maintenance Charge, and with respect to any principal prepayment on any Mortgage Loan and with respect to any Class of Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class A-S, Class B, Class C and Class D Regular Interests is a fraction (a) whose numerator is the greater of (x) zero and (y) the difference between (i) the Pass-Through Rate of such Class of Regular Interests and (ii) the discount rate used in accordance with the related Mortgage Loan documents in calculating the Yield Maintenance Charge with respect to such principal prepayment and (b) whose denominator is the greater of zero and the difference between (i) the Mortgage Rate on such Mortgage Loan (or with respect to any Mortgage Loan that is part of a Serviced Whole Loan, the Mortgage Rate of such Serviced Whole Loan) and (ii) the discount rate used in accordance with the related Mortgage Loan documents in calculating the Yield Maintenance Charge with respect to such principal prepayment; provided, however, that under no circumstances shall the Base Interest Fraction be greater than 1.0 or less than zero. If such discount rate is greater than or equal to the lesser of (x) the Mortgage Rate on the related Mortgage Loan or Serviced Whole Loan, as applicable, and (y) the Pass-Through Rate described in the preceding sentence, then the Base Interest Fraction shall equal zero; provided that if such discount rate is greater than or equal to the Mortgage Rate on such Mortgage Loan or Serviced Whole Loan, as applicable, but less than the Pass-Through Rate described in the preceding sentence, then the Base Interest Fraction shall equal 1.0. If a

 -379-

Mortgage Loan provides for a step-up in the Mortgage Rate, then the Mortgage Rate used in the determination of the Base Interest Fraction shall be the Mortgage Rate in effect at the time of the prepayment.

For purposes of the preceding paragraph, the relevant “Discount Rate” in connection with any Yield Maintenance Charge collected on any prepaid Mortgage Loan or REO Loan and distributable on any Distribution Date shall be a rate per annum equal to (i) if a discount rate was used in the calculation of the applicable Yield Maintenance Charge pursuant to the terms of the relevant Mortgage Loan or REO Loan, as the case may be, such discount rate (as reported by the Master Servicer), converted (if necessary) to a monthly equivalent yield, or (ii) if a discount rate was not used in the calculation of the applicable Yield Maintenance Charge pursuant to the terms of the relevant Mortgage Loan or REO Loan, as the case may be, the yield calculated by the linear interpolation of the yields (as reported under the heading “U.S. Government Securities/Treasury Constant Maturities” in Federal Reserve Statistical Release H.15 (519) published by the Federal Reserve Board for the week most recently ended before the date of the relevant prepayment (or deemed prepayment) of U.S. Treasury constant maturities with a maturity date, one longer and one shorter, most nearly approximating the related Stated Maturity Date (in the case of a Mortgage Loan or REO Loan that is not related to an ARD Loan) or the related Anticipated Repayment Date (in the case of a Mortgage Loan or REO Loan that is related to an ARD Loan)), such interpolated yield converted to a monthly equivalent yield. If Federal Reserve Statistical Release H.15 (519) is no longer published, the Master Servicer shall select a comparable publication as the source of the applicable yields of U.S. Treasury constant maturities, and the Master Servicer shall incur no liability with respect thereto.

(i)       No Yield Maintenance Charge shall be distributed to the Holders of the Class E Regular Interest, Class F Regular Interest, Class NR Regular Interest, Class R Certificates or Class Z Certificates. After the Certificate Balances and Notional Amounts of the Class A-1 Regular Interest, Class A-2 Regular Interest, Class A-3 Regular Interest, Class A-4 Regular Interest, Class A-5 Regular Interest, Class A-SB Regular Interest, Class X-A Regular Interest, Class X-B Regular Interest, Class A-S Regular Interest, Class B Regular Interest, Class C Regular Interest and Class D Regular Interest have been reduced to zero, Yield Maintenance Charges with respect to the Mortgage Loans shall be distributed to the Holder of the Class X-B Regular Interest.

(ii)      All distributions of Yield Maintenance Charges made (i) in respect of the respective Classes of Pooled Regular Interests on each Distribution Date pursuant to Section 4.01(i) shall first be deemed to be distributed from the Lower-Tier REMIC to the Upper-Tier REMIC in respect of the Lower-Tier Regular Interests, pro rata based upon the amount of principal distributed in respect of each such Class of Lower-Tier Regular Interests for such Distribution Date pursuant to Section 4.01(i) above; (ii) in respect of the Y&L Towers Loan-Specific Certificates on each Distribution Date pursuant to Section 4.01(i) shall first be deemed to be distributed from the Y&L Towers Trust Subordinate Companion Loan REMIC Distribution Account to the Upper-Tier REMIC in respect of the Y&L Towers Companion Loan REMIC Regular Interests, pro rata based on the amount of principal distributed in respect of each such Class of Y&L Towers Companion Loan REMIC Regular Interests for such Distribution Date pursuant to Section 4.01(i) and (iii) in respect of the Standard Highline Loan-Specific Certificates on

 -380-

each Distribution Date pursuant to Section 4.01(i) shall first be deemed to be distributed from the Standard Highline Trust Subordinate Companion Loan REMIC Distribution Account to the Upper-Tier REMIC in respect of the Standard Highline Companion Loan REMIC Regular Interests, pro rata based on the amount of principal distributed in respect of each such Class of the Standard Highline Companion Loan REMIC Regular Interests for such Distribution Date pursuant to Section 4.01(i).

(iii)     On each Distribution Date, any Yield Maintenance Charges payable in respect of the Yorkshire & Lexington Towers Whole Loan and received during the related Collection Period and allocable in respect of the Y&L Towers Trust Subordinate Companion Loan pursuant to the Y&L Towers Intercreditor Agreement shall be distributed to the Y&L Towers Loan-Specific Certificates by the Certificate Administrator in the following manner: (i) first, to the holders of the Class UES-A, Class UES-B, Class UES-C and Class UES-D Certificates in an amount equal to the product of (x) a fraction whose numerator is the amount of principal distributed to such class of Y&L Towers Loan-Specific Certificates on such Distribution Date and whose denominator is the total amount of principal distributed to the holders of the Class UES-A, Class UES-B, Class UES-C and Class UES-D Certificates on such Distribution Date, (y) the Y&L Towers Base Interest Fraction for the related principal prepayment and such class of Y&L Towers Loan-Specific Certificates and (z) the aggregate amount of such Yield Maintenance Charges allocated to the Y&L Towers Trust Subordinate Companion Loan and (ii) then, the portion of such yield maintenance charge remaining after such distributions to the Class UES-A, Class UES-B, Class UES-C and Class UES-D Certificates, to the holders of the Class UES-X Certificates. If there is more than one Class of Y&L Towers Loan-Specific Certificates entitled to distributions of principal on any particular Distribution Date on which Yield Maintenance Charges are distributable to such Class(es) of Certificates, the aggregate amount of such Yield Maintenance Charges will be allocated among all such Classes of Y&L Towers Loan-Specific Certificates up to, and on a pro rata basis in accordance with, their respective entitlements in those Yield Maintenance Charges in accordance with the first sentence of this paragraph. If any Yield Maintenance Charges remain undistributed after the distributions referred to above have been made, such remaining amounts will be distributed to the Holders of the Class UES-A, Class UES-B, Class UES-C and Class UES-D Certificates pro rata, based upon the principal distributions allocated to such Classes for such period.

Any funds not distributed to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure of such Holder or Holders to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited to the account or accounts of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been given pursuant to this Section 4.01(l) shall not have been surrendered for cancellation within six (6) months after the time specified in such notice, the Certificate Administrator shall mail a second notice to the remaining non-tendering Certificateholders to surrender their Certificates for cancellation in order to receive the final distribution with respect thereto. If within one year after the second notice all such Certificates shall not have been surrendered for cancellation, the Certificate Administrator, directly or through an agent, shall take such steps to contact the remaining non-tendering Certificateholders concerning the surrender of their Certificates as it shall deem appropriate and subject to escheatment and other

 -385-

applicable laws. The costs and expenses of holding such funds in trust and of contacting such Certificateholders following the first anniversary of the delivery of such second notice to the non-tendering Certificateholders shall be paid out of such funds. No interest shall accrue or be payable to any Certificateholder on any amount held in trust hereunder by the Certificate Administrator as a result of such Certificateholder’s failure to surrender its Certificate(s) for final payment thereof in accordance with this Section 4.01(l).

(m)         Distributions in reimbursement of Realized Losses previously allocated to the Regular Certificates shall be made in the amounts and manner specified in Section 4.01(a), Section 4.01(b), Section 4.01(c), Section 4.01(d) or Section 4.01(g), as applicable, to the Holders of the respective Class otherwise entitled to distributions of interest and principal on such Class on the relevant Distribution Date; provided that all distributions in reimbursement of Realized Losses previously allocated to a Class of Certificates which has since been retired shall be to the prior Holders that surrendered the Certificates of such Class upon retirement thereof and shall be made by check mailed to the address of each such prior Holder last shown in the Certificate Register. Notice of any such distribution to a prior Holder shall be made in accordance with Section 13.05 at such last address. The amount of the distribution to each such prior Holder shall be based upon the aggregate Percentage Interest evidenced by the Certificates surrendered thereby. If the check mailed to any such prior Holder is returned uncashed, then the amount thereof shall be set aside and held uninvested in trust for the benefit of such prior Holder, and the Certificate Administrator shall attempt to contact such prior Holder in the manner contemplated by Section 4.01(l) as if such Holder had failed to surrender its Certificates.

(n)          On each Distribution Date, any Excess Interest received during the related Collection Period with respect to the Mortgage Loans shall be distributed to the Holders of the Class V1-Z, Class V2-Z and Class Z Certificates from the Excess Interest Distribution Account.

All distributions from the Companion Distribution Account required hereunder shall be made by the Companion Paying Agent to the related Companion Holder by wire transfer in immediately available funds on the Serviced Whole Loan Remittance Date to the account of such Companion Holder or an agent therefor appearing on the Companion Register on the related Record Date (or, if no such account so appears or information relating thereto is not provided at least five Business Days prior to the related Record Date, by check sent by first class mail to the address of such Companion Holder or its agent appearing on the Companion Register). Any such account shall be located at a commercial bank in the United States.

On the final Master Servicer Remittance Date, the Master Servicer shall withdraw from the Collection Account and deliver to the Certificate Administrator who shall distribute to the Mortgage Loan Sellers, any Loss of Value Payments relating to the Mortgage Loans that it is servicing and that were transferred from the Loss of Value Reserve Fund to the Collection Account on the immediately preceding Master Servicer Remittance Date.

(c)          Each of the Master Servicer and the Special Servicer may, at its sole cost and expense, make available by electronic media, bulletin board service or Internet website (in addition to making information available as provided herein) any reports or other information the Master Servicer or the Special Servicer, as applicable, is required or permitted to provide to any party to this Agreement, the Rating Agencies or any Certificateholder or any prospective Certificateholder that has provided the Certificate Administrator, the Master Servicer or the Special Servicer, as applicable, with an Investor Certification or has executed a “click-through” confidentiality agreement in accordance with Section 3.13 hereof (which may be a licensed or registered investment advisor) to the extent such action does not conflict with the terms of this Agreement (including without limitation, any requirements to keep Privileged Information confidential), the terms of the Mortgage Loans or applicable law. Notwithstanding this paragraph, the availability of such information or reports on the Internet or similar electronic media shall not be deemed to satisfy any specific delivery requirements in this Agreement except

 -391-

as set forth herein. In connection with providing access to the Master Servicer’s or Special Servicer’s Internet website, the Master Servicer or the Special Servicer, as applicable, shall take reasonable measures to ensure that only such parties listed above may access such information including, without limitation, requiring registration, a confidentiality agreement and acceptance of a disclaimer. The Master Servicer or the Special Servicer, as applicable, shall not be liable for dissemination of this information in accordance with this Agreement, and neither the Master Servicer nor the Special Servicer shall be responsible for any information delivered, produced, or made available pursuant to Section 3.13 and 4.02(c), other than information produced by the Master Servicer or the Special Servicer, as applicable; provided that such information otherwise meets the requirements set forth herein with respect to the form and substance of such information or reports.

The Master Servicer or the Special Servicer may affix to any information provided by it any disclaimer it deems appropriate in its reasonable discretion (without suggesting liability on the part of any other party hereto).

the Certificate Administrator shall have any responsibility for the sufficiency under Rule 144A or any other securities laws of any available information so furnished to any person including any prospective purchaser of a Certificate or any interest therein, nor for the content or accuracy of any information so furnished which was prepared or delivered to them by another.

(e)          The information to which any Certificateholder is entitled is limited to the information gathered and provided to the Certificateholder by the parties hereto pursuant to this Agreement and by acceptance of any Certificate, each Certificateholder agrees that except as specifically provided herein, no Certificateholder shall contact any Mortgagor directly with respect to any Mortgage Loan.

(f)           Upon the reasonable request of the Directing Holder or any Controlling Class Certificateholder that, in either case, is an Excluded Controlling Class Holder with respect to any Excluded Controlling Class Loan identified to the Master Servicer’s (in the case of a Non-Specially Serviced Loan) or the Special Servicer’s (in the case of a Specially Serviced Loan) reasonable satisfaction (at the expense of the Directing Holder or such Controlling Class Certificateholder) and if such information is in the Master Servicer’s or the Special Servicer’s possession, as applicable, the Master Servicer or the Special Servicer, shall provide or make available (or forward electronically) to the Directing Holder or such Controlling Class Certificateholder, as applicable, (at the expense of the Directing Holder or such Controlling Class Certificateholder, as applicable) any Excluded Information (available to Privileged Persons through the Certificate Administrator’s Website but not accessible to the Directing Holder or such Controlling Class Certificateholder on account of it constituting Excluded Information, as applicable, through the Certificate Administrator’s Website because the Directing Holder or such Controlling Class Certificateholder, as applicable, is an Excluded Controlling Class Holder with respect to another Excluded Controlling Class Loan) relating to any Excluded Controlling Class Loan with respect to which the Directing Holder or such Controlling Class Certificateholder, as applicable, is not a Borrower Party; provided that, in connection therewith, the Master Servicer or the Special Servicer may require a written confirmation executed by the requesting Person substantially in such form as may be reasonably acceptable to the Master Servicer or the Special Servicer, generally to the effect that such Person is the Directing Holder or a Controlling Class Certificateholder will keep such Excluded Information confidential and is not a Borrower Party, upon which the Master Servicer or the Special Servicer may conclusively rely. In addition, the Master Servicer and the Special Servicer shall be entitled to conclusively rely on delivery from the Directing Holder or a Controlling Class Certificateholder, of an Investor Certification substantially in the form of Exhibit P-1D that such Directing Holder or Controlling Class Certificateholder, is not an Excluded Controlling Class Holder with respect to a particular Mortgage Loan. For the avoidance of doubt, the Special Servicer referenced in this Section 4.02(f) shall include any applicable Excluded Special Servicer with respect to the related Excluded Special Servicer Loan(s).

Section 4.03     P&I Advances. (a) On or before 4:00 p.m., New York City time, on each P&I Advance Date, the Master Servicer shall (i) remit to the Certificate Administrator for deposit from its own funds into the (A) Lower-Tier REMIC Distribution Account, an amount equal to the aggregate amount of P&I Advances, if any, with respect to the Mortgage Loans to be made in respect of the related Distribution Date and (B) the applicable Trust Subordinate Companion Loan REMIC Distribution Account, an amount equal to the aggregate amount of

 -393-

P&I Advances, if any, with respect to the related Trust Subordinate Companion Loan to be made in respect of the related Distribution Date, (ii) apply amounts held in the Collection Account, for future distribution to Certificateholders in subsequent months in discharge of any such obligation to make P&I Advances or (iii) make P&I Advances in the form of any combination of (i) and (ii) aggregating the total amount of P&I Advances to be made. Any amounts held in the Collection Account for future distribution and so used to make P&I Advances with respect to the Mortgage Loans or the Trust Subordinate Companion Loans shall be appropriately reflected in the Master Servicer’s records and replaced by the Master Servicer by deposit in the Collection Account on or before the next succeeding P&I Advance Date (to the extent not previously replaced through the deposit of Late Collections of the delinquent principal and/or interest in respect of which P&I Advances were made). The Master Servicer shall notify the Certificate Administrator of (i) the aggregate amount of P&I Advances with respect to the Mortgage Loans, the Trust Subordinate Companion Loans and any REO Mortgage Loans for a Distribution Date and (ii) the amount of any Nonrecoverable P&I Advances with respect to the Mortgage Loans or the Trust Subordinate Companion Loans and any REO Mortgage Loans for such Distribution Date. If the Master Servicer fails to make a required P&I Advance by 4:00 p.m., New York City time, on any P&I Advance Date, the Trustee shall make such P&I Advance pursuant to Section 7.05 by noon, New York City time, on the related Distribution Date, unless the Master Servicer shall have cured such failure (and provided written notice of such cure to the Trustee and the Certificate Administrator) by 11:00 a.m., New York City time, on such Distribution Date. In the event that the Master Servicer fails to make a required P&I Advance hereunder, the Certificate Administrator shall notify the Trustee of such circumstances by 4:30 p.m., New York City time, on the related P&I Advance Date. Notwithstanding the foregoing, the portion of any P&I Advance equal to the CREFC^® Intellectual Property Royalty License Fee for the related Mortgage Loans or the Trust Subordinate Companion Loans and any REO Mortgage Loans shall not be remitted to the Certificate Administrator for deposit into the Lower-Tier REMIC Distribution Account but shall be deposited into the Collection Account for payment to CREFC^® on such Distribution Date.

(b)          Subject to Section 4.03(c) and Section 4.03(e) below, the amount of P&I Advances to be made by the Master Servicer with respect to any Distribution Date and all Mortgage Loans, the Trust Subordinate Companion Loans and REO Mortgage Loans, shall be equal to: (i) the Periodic Payments (net of related Servicing Fees and, in the case of any Non-Serviced Mortgage Loan, a fee accruing at the related Non-Serviced Primary Servicing Fee Rate) other than Balloon Payments, that were due on the Mortgage Loans (including any Non-Serviced Mortgage Loan), the Trust Subordinate Companion Loans and any REO Loan (including any portion of an REO Loan related to a Trust Subordinate Companion Loan, but excluding any portion of an REO Loan related to any other Companion Loan) during the related Collection Period and delinquent as of the close of business on the Business Day preceding the related P&I Advance Date (or not advanced by any Sub-Servicer on behalf of the Master Servicer) and (ii) with respect to each Mortgage Loan or Trust Subordinate Companion Loan delinquent in respect of its Balloon Payment as of the close of business on the Business Day preceding the related P&I Advance Date (including any REO Loan (including any portion of a REO Loan related to the a Trust Subordinate Companion Loan, but excluding any portion of an REO Loan related to any other Companion Loan) as to which the related Balloon Payment would have been past due), an amount equal to the Assumed Scheduled Payment (or Y&L Towers Assumed Scheduled Payments, with respect to the Y&L Towers Trust Subordinate Companion Loan or

 -394-

Standard Highline Assumed Scheduled Payments, with respect to the Standard Highline Trust Subordinate Companion Loan) (net of any collections of previously unadvanced principal and interest (adjusted to the related Net Mortgage Rate) received with respect to such Mortgage Loan, the Trust Subordinate Companion Loan or REO Loan, as applicable, during the related Collection Period) therefor plus, without duplication, in the case of the Y&L Towers Trust Subordinate Companion Loan, the related Y&L Towers Diverted Amount. Subject to subsection (c) below, the obligation of the Master Servicer to make such P&I Advances is mandatory, and with respect to any Mortgage Loan (including any Non-Serviced Mortgage Loan), the Trust Subordinate Companion Loan or REO Loan (including any portion of a REO Loan related to the a Trust Subordinate Companion Loan but excluding any portion of an REO Loan related to any other Companion Loan), shall continue until the Distribution Date on which the proceeds, if any, received in connection with a Liquidation Event or the disposition of the REO Property, as the case may be, with respect thereto are to be distributed. Neither the Master Servicer nor the Trustee shall make or be permitted to make any P&I Advances with respect to any Companion Loan other than the a Trust Subordinate Companion Loan. The Special Servicer shall not make any P&I Advances on any Mortgage Loan or Companion Loan, including a Trust Subordinate Companion Loan.

(c)          Notwithstanding anything herein to the contrary, no P&I Advance shall be required to be made hereunder if such P&I Advance would, if made, constitute a Nonrecoverable P&I Advance. With respect to each Non-Serviced Mortgage Loan, the Master Servicer will be required to make its determination (based on information provided by the applicable Non-Serviced Master Servicer and Non-Serviced Special Servicer) that it has made a P&I Advance on such Non-Serviced Mortgage Loan that is a Nonrecoverable Advance or that any proposed P&I Advance would, if made, constitute a Nonrecoverable Advance with respect to such Non-Serviced Mortgage Loan independently of any determination made by the applicable Non-Serviced Master Servicer or the applicable Non-Serviced Special Servicer, as the case may be, under the applicable Non-Serviced PSA in respect of the related Non-Serviced Companion Loan. If the Master Servicer or the Special Servicer determines that a proposed P&I Advance with respect to a Non-Serviced Mortgage Loan, if made, or any outstanding P&I Advance with respect to a Non-Serviced Mortgage Loan previously made, would be, or is, as applicable, a Nonrecoverable Advance, the Master Servicer shall provide the applicable Non-Serviced Master Servicer and Non-Serviced Special Servicer written notice of such determination within two (2) Business Days of the date of such determination. If the Master Servicer receives written notice from the related Non-Serviced Master Servicer or the related Non-Serviced Special Servicer, as the case may be, that either has determined in accordance with the applicable Non-Serviced PSA with respect to a Non-Serviced Companion Loan, that any proposed advance under the applicable Non-Serviced PSA that is similar to a P&I Advance would be, or any outstanding advance under such Non-Serviced PSA that is similar to a P&I Advance is, a nonrecoverable advance, then the Master Servicer or the Trustee may, based upon such determination, determine that any P&I Advance previously made or proposed to be made with respect to the related Non-Serviced Mortgage Loan, will be a Nonrecoverable P&I Advance. Thereafter, in either case, the Master Servicer shall not be required to make any additional P&I Advances with respect to the related Non-Serviced Mortgage Loan unless and until the Master Servicer or the Trustee, as the case may be, determines that any such additional P&I Advances with respect to the related Non-Serviced Mortgage Loan would not be a Nonrecoverable P&I Advance, which determination

 -395-

may be as a result of consultation with the related Non-Serviced Master Servicer or the related Non-Serviced Special Servicer, as the case may be, or otherwise.

(d)          In connection with the recovery of any P&I Advance out of the Collection Account, pursuant to Section 3.05(a), the Master Servicer shall be entitled to pay the Trustee and itself (in that order of priority) as the case may be, out of any amounts then on deposit in the Collection Account (but in no event from any funds allocable to a Serviced Companion Noteholder (unless related thereto), except to the extent permitted pursuant to the terms of the related Intercreditor Agreement), interest at the Reimbursement Rate in effect from time to time, accrued on the amount of such P&I Advance from the date made to but not including the date of reimbursement; provided, however, that no interest will accrue on any P&I Advance (i) made with respect to a Mortgage Loan or Trust Subordinate Companion Loan until after the related Due Date has passed and any applicable Grace Period has expired or (ii) if the related Periodic Payment is received after the Determination Date but on or prior to the related P&I Advance Date. The Master Servicer shall reimburse itself and/or the Trustee, as the case may be, for any outstanding P&I Advance, subject to Section 3.17 of this Agreement, as soon as practicably possible after funds available for such purpose are deposited in the Collection Account.

In addition, the Master Servicer, the Special Servicer or the Trustee, as applicable, in making any recoverability determination respecting a P&I Advance in respect of a Trust Subordinate Companion Loan, shall look solely to the proceeds available in respect of such Trust Subordinate Companion Loan and shall be entitled to take into account the subordinate nature of such Trust Subordinate Companion Loan as well as (a) to consider (among other things) (i) the obligations of the Mortgagor under the terms of the related Mortgage Loan or Companion Loan as it may have been modified and (ii) the related Mortgaged Property in its “as-is” or then current condition and occupancy, as modified by such party’s assumptions (consistent with the Servicing Standard in the case of the Master Servicer or the Special Servicer or in its good faith business judgment in the case of the Trustee, solely in its capacity as Trustee) regarding the possibility and effects of future adverse change with respect to such Mortgaged Property, (b) to estimate and consider (consistent with the Servicing Standard in the case of the Master Servicer and the Special Servicer or in its good faith business judgment in the case of the Trustee, solely in its capacity as Trustee) (among other things) future expenses, (c) to estimate and consider (consistent with the applicable Servicing Standard in the case of the Master Servicer and the Special Servicer or in its good faith business judgment in the case of the Trustee, solely in its capacity as Trustee) (among other things) the timing of recoveries, (d) in the case of a potential P&I Advance with respect to a Trust Subordinate Companion Loan, the subordinate nature of such Trust Subordinate Companion Loan and (e) to give due regard to the existence of any Nonrecoverable Advances which, at the time of such consideration, the recovery of which are being deferred or delayed by the Master Servicer, in light of the fact that related proceeds are a source of recovery not only for the Advance under consideration but also a potential source of recovery for such delayed or deferred Advance.

(e)          Notwithstanding the foregoing, (i) neither the Master Servicer nor the Trustee shall make an advance for Excess Interest, Yield Maintenance Charges, Default Interest, late payment charges, Balloon Payment or any P&I Advance with respect to any Companion Loan (other than any Trust Subordinate Companion Loan) and (ii) if an Appraisal Reduction Amount has been determined to exist with respect to any Mortgage Loan (or, in the case of a

 -396-

Non-Serviced Whole Loan, an “appraisal reduction amount” (or similar item has been made in accordance with the related Non-Serviced PSA and the Master Servicer has notice of such appraisal reduction amount) or Trust Subordinate Companion Loan, then in the event of subsequent delinquencies thereon, the interest portion of the P&I Advance in respect of such Mortgage Loan or Trust Subordinate Companion Loan for the related Distribution Date shall be reduced (it being herein acknowledged that there shall be no reduction in the principal portion of such P&I Advance) to equal the product of (x) the amount of the interest portion of such P&I Advance for such Mortgage Loan or Trust Subordinate Companion Loan for such Distribution Date without regard to this clause 4.03(e)(ii), and (y) a fraction, expressed as a percentage, the numerator of which is equal to the Stated Principal Balance of such Mortgage Loan or Trust Subordinate Companion Loan immediately prior to such Distribution Date, net of the related Appraisal Reduction Amount (or, in the case of a Serviced Whole Loan, the portion of such Appraisal Reduction Amount allocated to the related Mortgage Loan or Trust Subordinate Companion Loan), if any, and the denominator of which is equal to the Stated Principal Balance of such Mortgage Loan or Trust Subordinate Companion Loan immediately prior to such Distribution Date. For purposes of the immediately preceding sentence, the Periodic Payment due on the Maturity Date for a Balloon Mortgage Loan will be the Assumed Scheduled Payment (or Y&L Towers Assumed Scheduled Payments, with respect to the Y&L Towers Trust Subordinate Companion Loan or Standard Highline Assumed Scheduled Payments, with respect to the Standard Highline Trust Subordinate Companion Loan) for the related Distribution Date.

(f)           In no event shall either the Master Servicer or the Trustee be required to make a P&I Advance with respect to any Companion Loan other than any Trust Subordinate Companion Loan.

Section 4.04     Allocation of Realized Losses. (a) On each Distribution Date, immediately following the distributions to be made on such date pursuant to Section 4.01, the Certificate Administrator shall calculate the amount, if any, by which (W) with respect to the Mortgage Loans (i) the aggregate Stated Principal Balance (for purposes of this definition only, not giving effect to any reductions of the Stated Principal Balance for payments of principal collected on the Mortgage Loans that were used to reimburse any Workout-Delayed Reimbursement Amounts pursuant to Section 3.05(a)(v) to the extent such Workout-Delayed Reimbursement Amounts are not otherwise determined to be Nonrecoverable Advances) of the Mortgage Loans and any REO Loans (excluding any portion allocable to any related Companion Loan other than the Y&L Towers Trust Subordinate Companion Loan or the Standard Highline Trust Subordinate Companion Loan, if applicable) expected to be outstanding immediately following such Distribution Date, is less than (ii) the then-aggregate Certificate Balance of the Pooled Regular Interests after giving effect to distributions of principal on such Distribution Date (any such deficit, the “Pooled Realized Loss”), (X) with respect to the Y&L Towers Trust Subordinate Companion Loan (i) the Stated Principal Balance of the Y&L Towers Trust Subordinate Companion Loan (including the assumed Stated Principal Balance if the Y&L Towers Trust Subordinate Companion Loan have become an REO Loan) expected to be outstanding immediately following such Distribution Date is less than (ii) the aggregate Certificate Balance of the Y&L Towers Loan-Specific Certificates after giving effect to distributions of principal on such Distribution Date (any such deficit with respect to the Y&L Towers Loan-Specific Certificates, the “Y&L Towers Realized Loss”) and (Y) with respect to the Standard Highline Trust Subordinate Companion Loan (i) the Stated Principal Balance of the

 -397-

Standard Highline Trust Subordinate Companion Loan (including the assumed Stated Principal Balance if the Standard Highline Trust Subordinate Companion Loan have become an REO Loan) expected to be outstanding immediately following such Distribution Date is less than (ii) the aggregate Certificate Balance of the Standard Highline Loan-Specific Certificates after giving effect to distributions of principal on such Distribution Date (any such deficit with respect to the Standard Highline Loan-Specific Certificates, the “Standard Highline Realized Loss”). Realized Losses with respect to the Yorkshire & Lexington Towers Whole Loan shall be allocated first to the Y&L Towers Trust Subordinate Companion Loan (and, correspondingly, to the Class UES-A, Class UES-B, Class UES-C and Class UES-D Regular Interests, as applicable, in reverse alphabetic order) and then to the Yorkshire & Lexington Towers Pari Passu Companion Loan and to the Yorkshire & Lexington Towers Mortgage Loan on a pro rata and pari passu basis. Realized Losses with respect to The Standard Highline NYC Whole Loan shall be allocated first to the Standard Highline Non-Trust Junior Subordinate Companion Loan, then to the Standard Highline Non-Trust Senior Subordinate Companion Loan, then to the Standard Highline Trust Subordinate Companion Loan (and, correspondingly, to the Class STN-A, Class STN-B and Class STN-C Regular Interests, as applicable, in reverse alphabetic order) and then to The Standard Highline NYC Mortgage Loan. Any allocation of Realized Losses to a Class of Regular Interests shall be made by reducing the Certificate Balance thereof by the amount so allocated. The allocation of Realized Losses shall constitute an allocation of losses and other shortfalls experienced by the Trust. Reimbursement of previously allocated Realized Losses will not constitute distributions of principal for any purpose and will not result in an additional reduction in the Certificate Balance of the applicable Regular Interest in respect of which any such reimbursement is made. With respect to any Regular Interest (other than any Class X Regular Interest), to the extent any Nonrecoverable Advances (plus interest thereon) that were reimbursed from principal collections on the Mortgage Loans, the Y&L Towers Trust Subordinate Companion Loan and/or the Standard Highline Trust Subordinate Companion Loan and previously resulted in a reduction of the Principal Distribution Amount, the Y&L Towers Principal Distribution Amount or the Standard Highline Principal Distribution Amount, as applicable, are subsequently recovered on the related Mortgage Loan and/or Trust Subordinate Companion Loan, the amount of such recovery will be added to the Certificate Balance of the Class or Classes of Regular Interest that previously were allocated Realized Losses and in the case of Realized Losses, in sequential order according to the priority of payments for the Regular Interests (other than the Class X Regular Interests) (and in the case of the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5 and Class A-SB Regular Interests, on a pro rata basis according to the amount of unreimbursed Realized Losses on such Classes), in each case up to the amount of the unreimbursed Realized Losses allocated to such Class of Regular Interest (other than the Loan-Specific Regular Interests).

(b)          (i) On each Distribution Date, the Certificate Balances of each Pooled Regular Interest (other than the Class X Regular Interests) will be reduced without distribution, as a write-off to the extent of any Pooled Realized Losses, if any, allocable to such Certificates with respect to such Distribution Date. Any such write-off shall be allocated first, to the Class NR Regular Interest, second, to the Class F Regular Interest, third, to the Class E Regular Interest, fourth, to the Class D Regular Interest, fifth, to the Class C Regular Interest, sixth, to the Class B Regular Interest, seventh, to the Class A-S Regular Interest, and then, pro rata (based on their respective Certificate Balances), Class A-1, Class A-2, Class A-3, Class A-4, Class A-5 and Class A-SB Regular Interests, in each case until the remaining Certificate Balances of such

 -398-

Regular Interests have been reduced to zero. On each Distribution Date, the Certificate Balances of the Y&L Towers Loan-Specific Regular Interests will be reduced without distribution as a write-off to the extent of any Y&L Towers Realized Losses attributable to the Y&L Towers Trust Subordinate Companion Loan in accordance with Section 4.04(a). Any such write-off with respect to the Y&L Towers Trust Subordinate Companion Loan shall be allocated first, to the Class UES-D Regular Interest, then, to the Class UES-C Regular Interest, then, to the Class UES-B Regular Interest, then, to the Class UES-A Regular Interest, in each case until the remaining Certificate Balances of such Regular Interests have been reduced to zero. On each Distribution Date, the Certificate Balances of the Standard Highline Loan-Specific Regular Interests will be reduced without distribution as a write-off to the extent of any the Standard Highline Realized Losses attributable to the Standard Highline Trust Subordinate Companion Loan in accordance with Section 4.04(a). Any such write-off with respect to the Standard Highline Trust Subordinate Companion Loan shall be allocated first, to the Class STN-C Regular Interest, then, to the Class STN-B Regular Interest, then, to the Class STN-A Regular Interest, in each case until the remaining Certificate Balances of such Regular Interests have been reduced to zero.

As of the first Determination Date following a Mortgage Loan (other than a Non-Serviced Mortgage Loan) or Trust Subordinate Companion Loan becoming an AB Modified Loan, the Special Servicer shall calculate whether a Collateral Deficiency Amount exists with respect to such AB Modified Loan, taking into account the most recent Appraisal obtained by the Special Servicer with respect to such Mortgage Loan or Trust Subordinate Companion Loan, and all other information relevant to a Collateral Deficiency Amount determination. Upon obtaining knowledge or receiving notice by the Master Servicer that a Non-Serviced Mortgage Loan has become an AB Modified Loan, the Master Servicer shall (i) promptly request from the related Non-Serviced Master Servicer, Non-Serviced Special Servicer and Non-Serviced Trustee the most recent appraisal with respect to such AB Modified Loan, in addition to all other information reasonably required by the Master Servicer to calculate whether a Collateral Deficiency Amount exists with respect to such AB Modified Loan, and (ii) as of the first Determination Date following receipt by the Master Servicer of the appraisal and any other information set forth in the immediately preceding clause (i) that the Master Servicer reasonably expects to receive, calculate whether a Collateral Deficiency Amount exists with respect to such AB Modified Loan, taking into account the most recent appraisal obtained by the Non-Serviced Special Servicer with respect to such Non-Serviced Mortgage Loan, and all other information relevant to a Collateral Deficiency Amount determination. Upon obtaining knowledge or receipt of notice by any other party to this Agreement that a Non-Serviced Mortgage Loan has become an AB Modified Loan, such party shall promptly notify the Master Servicer thereof.

For the avoidance of doubt, for purposes of determining the Controlling Class or the occurrence and continuance of a Control Termination Event, any Class of Control Eligible Corresponding Certificates shall be allocated both applicable Appraisal Reduction Amounts and applicable Collateral Deficiency Amounts (the sum of which shall constitute the applicable Cumulative Appraisal Reduction Amount), in accordance with this Section 4.05(a).

For the avoidance of doubt, for purposes of determining the Y&L Towers Controlling Class and the occurrence of a Y&L Towers Trust Subordinate Companion Loan Control Termination Event, any Class of Y&L Towers Loan-Specific Certificates will be allocated both applicable Appraisal Reduction Amounts and applicable Collateral Deficiency Amounts, as described in this paragraph.

For purposes of determining the Non-Reduced Loan-Specific Regular Interests, the Standard Highline Controlling Class and the occurrence of a Standard Highline Non-Trust Junior Subordinate Control Termination Event, a Standard Highline Non-Trust Senior Subordinate Control Termination Event or a Standard Highline Trust Subordinate Control Termination Event, Appraisal Reduction Amounts allocated to The Standard Highline NYC Whole Loan will be allocated first to the Standard Highline Non-Trust Junior Subordinate Companion Loan, then to the Standard Highline Non-Trust Senior Subordinate Companion Loan, then to the Standard Highline Trust Subordinate Companion Loan and then to The Standard Highline NYC Mortgage Loan.

The Special Servicer (in the case of a Mortgage Loan other than a Non-Serviced Mortgage Loan) or the Master Servicer (in the case of a Non-Serviced Mortgage Loan) shall promptly notify the Special Servicer or the Master Servicer, as applicable, and the Master Servicer shall notify the Certificate Administrator of the amount of any Appraisal Reduction Amount (which notification to the Certificate Administrator shall be made by delivery of such information included in the CREFC® Loan Periodic Update File in accordance with Section 3.12(d)), any Collateral Deficiency Amount and any resulting Cumulative Appraisal Reduction Amount allocated to each Mortgage Loan, AB Modified Loan or Serviced Whole Loan (which notification may be satisfied through delivery of such information included in the CREFC® Appraisal Reduction Amount Template included in the CREFC® Investor Reporting Package in accordance with Section 3.12(d) or such other report or reports mutually agreed upon between the Master Servicer and the Certificate Administrator) and the Certificate Administrator shall promptly post notice of such Appraisal Reduction Amount, Collateral Deficiency Amount and/or Cumulative Appraisal Reduction Amount, as applicable, to the Certificate Administrator’s Website. Based on information in its possession, the Certificate Administrator shall determine from time to time which Class of Certificates is the Controlling Class. Promptly upon its determination of a change in the Controlling Class, the Certificate Administrator shall notify the Master Servicer, the Special Servicer and the Operating Advisor of such event, including the identity and contact information of the new Controlling Class Certificateholder and the identity of the Controlling Class as set forth in Section 3.23(m) (the cost of obtaining such information from the Depository being an expense of the Trust).

(b)         (i) The Holders of the majority of Voting Rights of any Class of Control Eligible Corresponding Certificates or Loan-Specific Certificates respectively, that is determined at any time of determination to no longer be the Controlling Class, the Y&L Towers Controlling Class or the Standard Highline Controlling Class (any such Class, an “Appraised-Out Class”) as a result of an Appraisal Reduction Amount or Collateral Deficiency Amount (as applicable) in respect of such Class shall have the right, at their sole expense, to require the Special Servicer to order (or, with respect to a Collateral Deficiency Amount calculation for a Non-Serviced Mortgage Loan, require the Master Servicer to request from the applicable Non-Serviced Special Servicer) a second Appraisal with respect to any Mortgage Loan (or Serviced Whole Loan) for

 -406-

which an Appraisal Reduction Event has occurred or as to which there exists a Collateral Deficiency Amount (such Holders, the “Requesting Holders”). With respect to any such Mortgage Loan (other than with respect to a Non-Serviced Mortgage Loan), the Special Servicer shall use its reasonable efforts to cause such second Appraisal to be (i) delivered within thirty (30) days from receipt of the Requesting Holders’ written request and (ii) prepared on an “as-is” basis by an MAI appraiser (provided that such MAI appraiser may not be the same MAI appraiser that provided the Appraisal in respect of which the Requesting Holders are requesting the Special Servicer to obtain an additional Appraisal). With respect to any such Non-Serviced Mortgage Loan, the Master Servicer shall use commercially reasonable efforts to obtain such second appraisal from the applicable Non-Serviced Special Servicer.

(ii)       Upon receipt of any supplemental Appraisal pursuant to clause (i) above, the Master Servicer (for Collateral Deficiency Amounts on Non-Serviced Mortgage Loans), the applicable Non-Serviced Special Servicer (for Appraisal Reduction Amounts on Non-Serviced Mortgage Loans to the extent provided for in the applicable Non-Serviced PSA and applicable Intercreditor Agreement) and the Special Servicer (for Mortgage Loans other than Non-Serviced Mortgage Loans) shall determine, in accordance with the Servicing Standard, whether, based on its assessment of such supplemental Appraisal, any recalculation of the Appraisal Reduction Amount or Collateral Deficiency Amount (as applicable) is warranted, and if so warranted, the Special Servicer shall recalculate the Appraisal Reduction Amount or Collateral Deficiency Amount, as applicable, based on such supplemental appraisal. If required by such recalculation, the Appraised-Out Class shall be reinstated as the Controlling Class, the Y&L Towers Controlling Class or the Standard Highline Controlling Class, as applicable, and each other Appraised-Out Class shall, if applicable, have its related Certificate Balance notionally restored to the extent required by such recalculation of the Appraisal Reduction Amount or Collateral Deficiency Amount, if applicable. In addition, the Requesting Holders of any Appraised-Out Class shall have the right, at their sole expense, to require the Special Servicer to order an additional appraisal of any Mortgage Loan for which an Appraisal Reduction Event has occurred or as to which there exists a Collateral Deficiency Amount, and the Special Servicer shall use its reasonable efforts to obtain such appraisal from an MAI appraiser reasonably acceptable to the Special Servicer within thirty (30) days from receipt of the Requesting Holders’ written request; provided, that the Special Servicer shall not be required to obtain such appraisal if it determines in accordance with the Servicing Standard that no events at or with regard to the related Mortgaged Property or Mortgaged Properties have occurred that would have a material effect on the appraised value of the related Mortgaged Property or Mortgaged Properties. The Holders of an Appraised-Out Class requesting any supplemental Appraisal pursuant to clause (i) above shall refrain from exercising any direction, control, consent and/or similar rights of the Controlling Class, the Y&L Towers Controlling Class or the Standard Highline Controlling Class, as applicable, until such time, if any, as the Class is reinstated as the Controlling Class, the Y&L Towers Controlling Class or the Standard Highline Controlling Class as applicable (such period beginning upon receipt by the Special Servicer of any request to obtain a supplemental Appraisal pursuant to clause (i) above to but excluding the date on which either (A) the Special Servicer determines that no recalculation of the Appraisal Reduction Amount or Collateral Deficiency Amount (as applicable) is warranted or (B) the Special Servicer recalculates the Appraisal Reduction

 -407-

Amount or Collateral Deficiency Amount (as applicable) based on the supplemental Appraisal, the “Appraisal Review Period”). The rights of the Controlling Class, the Y&L Towers Controlling Class or the Standard Highline Controlling Class during each Appraisal Review Period shall be exercised by the most senior Class of Control Eligible Corresponding Certificates, if any, Y&L Towers Loan-Specific Certificates or Standard Highline Loan-Specific Certificates, if any, respectively.

(c)         With respect to each Mortgage Loan (other than a Non-Serviced Mortgage Loan) and any Serviced Whole Loan as to which an Appraisal Reduction Event has occurred (unless such Mortgage Loan or Serviced Whole Loan has remained current for three consecutive Periodic Payments, and with respect to which no other Appraisal Reduction Event has occurred with respect to that Mortgage Loan during the preceding three months (for such purposes taking into account any amendment or modification of such Mortgage Loan, any related Companion Loan or Serviced Whole Loan)), the Special Servicer shall (1) within thirty (30) days of the occurrence or of each anniversary of the related Appraisal Reduction Event, and (2) upon its determination that the value of the related Mortgaged Property has materially changed, notify the Master Servicer of the occurrence of such anniversary or determination and order an Appraisal (which may be an update of a prior Appraisal), the cost of which shall be paid by the Master Servicer as a Servicing Advance or to the extent it would be a Nonrecoverable Advance, an expense of the Trust, or conduct an internal valuation, as applicable, and promptly following receipt of any such Appraisal or performance of such valuation (or receipt of any Appraisal obtained in accordance with Section 4.05(b) above), shall promptly deliver a copy thereof to the Master Servicer, the Certificate Administrator, the Trustee, the Operating Advisor and ((i) prior to the occurrence and continuance of any Consultation Termination Event and (ii) other than with respect to any Mortgage Loan that is an Excluded Loan with respect to the Directing Holder or, if the Directing Holder is the Directing Certificateholder, the Holder of the majority of the Controlling Class) the Directing Holder. Based upon such Appraisal or internal valuation (or any Appraisal obtained in accordance with Section 4.05(b) above) and receipt of information reasonably requested by the Special Servicer from the Master Servicer necessary to calculate the Appraisal Reduction Amount that is either in the Master Servicer’s possession or reasonably obtainable by the Master Servicer, the Special Servicer shall determine or redetermine, as applicable, and report to the Master Servicer, the Certificate Administrator, the Trustee, the Operating Advisor and ((i) prior to the occurrence and continuance of any Consultation Termination Event and (ii) other than with respect to any Mortgage Loan that is an Excluded Loan as to such party) the Directing Holder, the amount and calculation or recalculation of the Appraisal Reduction Amount or Collateral Deficiency Amount with respect to such Mortgage Loan, Companion Loan or Serviced Whole Loan, as applicable, and such report shall be delivered in the CREFC^® Appraisal Reduction Amount Template format; provided, however, that the Special Servicer shall not be liable for failure to comply with such duties insofar as such failure results from a failure of the Master Servicer to provide sufficient information to the Special Servicer to comply with such duties or failure by the Master Servicer to otherwise comply with its obligations hereunder. Such report shall also be forwarded by the Master Servicer (or the Special Servicer if the related Mortgage Loan is a Specially Serviced Loan), to the extent the related Serviced Companion Loan has been included in an Other Securitization, to the Other Servicer, to the extent required by the related Intercreditor Agreement, of such Other Securitization into which the related Serviced Companion Loan has been sold, or to the holder of any related Serviced Companion Loan by the Master Servicer (or the Special Servicer if the

 -408-

related Mortgage Loan is a Specially Serviced Loan). If the Special Servicer is required to redetermine the Appraisal Reduction Amount or Collateral Deficiency Amount, such redetermined Appraisal Reduction Amount or Collateral Deficiency Amount shall replace the prior Appraisal Reduction Amount or Collateral Deficiency Amount, as applicable, with respect to such Mortgage Loan, Companion Loan or Serviced Whole Loan, as applicable. Prior to the occurrence and continuance of a Consultation Termination Event (and unless the related Mortgage Loan is an Excluded Loan as to such party), the Special Servicer shall consult with the Directing Holder with respect to any Appraisal, valuation or downward adjustment in connection with an Appraisal Reduction Amount or Collateral Deficiency Amount. Notwithstanding the foregoing but subject to Section 4.05(b), the Special Servicer shall not be required to obtain an Appraisal or conduct an internal valuation, as applicable, with respect to a Mortgage Loan or related Companion Loan or Serviced Whole Loan as to which an Appraisal Reduction Event has occurred to the extent the Special Servicer has obtained an Appraisal or conducted such a valuation (in accordance with requirements of this Agreement), as applicable, with respect to the related Mortgaged Property within the six-month period immediately prior to the occurrence of such Appraisal Reduction Event. Instead, the Special Servicer may use such prior Appraisal or valuation, as applicable, in calculating any Appraisal Reduction Amount with respect to such Mortgage Loan or related Companion Loan or Serviced Whole Loan; provided that the Special Servicer is not aware of any material change to the related Mortgaged Property having occurred and affecting the validity of such Appraisal or valuation.

The Master Servicer shall deliver by electronic mail to the Special Servicer any information in its possession reasonably required to determine, calculate, redetermine or recalculate any Appraisal Reduction Amount, using reasonable efforts to deliver such information, within four (4) Business Days following the Special Servicer’s reasonable request therefor (which request must be made promptly after the Special Servicer’s receipt of the applicable appraisal or preparation of the applicable internal evaluation); provided that the Special Servicer’s failure to timely make such request shall not relieve the Master Servicer of its obligation to use reasonable efforts to provide such information to the Special Servicer within four (4) Business Days following the Special Servicer’s reasonable request.

(d)         Any Mortgage Loan (other than any Non-Serviced Mortgage Loan), any related Serviced Companion Loan and any Serviced Whole Loan previously subject to an Appraisal Reduction Amount, which has become a Corrected Loan (for such purposes taking into account any amendment or modification of such Mortgage Loan, any related Serviced Companion Loan and any Serviced Whole Loan), and with respect to which no other Appraisal Reduction Event has occurred and is continuing, will no longer be subject to an Appraisal Reduction Amount. Any Appraisal Reduction Amount in respect of a Non-Serviced Whole Loan shall be calculated by the applicable party under and in accordance with and pursuant to the terms of the applicable Non-Serviced PSA.

(e)          Each Serviced Whole Loan will be treated as a single Mortgage Loan for purposes of calculating an Appraisal Reduction Amount with respect to the Mortgage Loan and Companion Loan(s) that comprise such Serviced Whole Loan. Any Appraisal Reduction Amount in respect of a Serviced AB Whole Loan will be allocated in accordance with the related Intercreditor Agreement or, if no allocation is specified in the related Intercreditor Agreement, then, first, to the related AB Subordinate Companion Loan (or with respect to The Standard

 -409-

Highline NYC Whole Loan, first, to the Standard Highline Non-Trust Junior Subordinate Companion Loan, then, to the Standard Highline Non-Trust Senior Subordinate Companion Loan and then, to the Standard Highline Trust Subordinate Companion Loan) (until its principal balance is notionally reduced to zero by such Appraisal Reduction Amounts) and then, pro rata, to the related AB Mortgage Loan and any related Pari Passu Companion Loan(s). Any Appraisal Reduction Amount in respect of any Serviced Pari Passu Whole Loan will be allocated in accordance with the related Intercreditor Agreement or, if no allocation is specified in the related Intercreditor Agreement, then, pro rata, between the related Serviced Pari Passu Mortgage Loan and the related Serviced Pari Passu Companion Loan(s), based upon their respective outstanding principal balances.

Section 4.06     Grantor Trust Reporting. (a) The parties intend that the portion of the Trust Fund constituting the Grantor Trust shall constitute, and that the affairs of the Grantor Trust shall be conducted so as to qualify such portion as, a “grantor trust” under subpart E, part I of subchapter J of the Code, and the provisions hereof shall be interpreted consistently with this intention. In furtherance of such intention, neither the Trustee nor the Certificate Administrator shall have the power to vary the investment of the Certificateholders in the Grantor Trust so as to improve their rate of return. The Certificate Administrator shall prepare or cause to be prepared, submit to the Trustee for execution (and the Trustee shall timely execute and timely return to the Certificate Administrator) and timely file all Tax Returns in respect of the Grantor Trust. In addition, the Certificate Administrator shall (A) file, or cause to be filed, Internal Revenue Service Form 1041, Form 1099 or such other form as may be applicable with the Internal Revenue Service with copies of the statements in the following clause and (B) furnish, or cause to be furnished, to the Certificateholders, their allocable share of income and expense with respect to the related Specific Grantor Trust Assets in the time or times and in the manner required by the Code.

(b)       The Grantor Trust will be treated as a WHFIT that is a WHMT. The Certificate Administrator will report as required under the WHFIT Regulations to the extent such information as is reasonably necessary to enable the Certificate Administrator to do so is provided to the Certificate Administrator on a timely basis. The Certificate Administrator is hereby directed to assume that DTC is the only “middleman” as defined by the WHFIT Regulations unless the Depositor provides the Certificate Administrator with the identities of other “middlemen” that are Certificateholders. The Certificate Administrator shall be entitled to rely on the first sentence of this Section 4.06(b) and shall be entitled to indemnification in accordance with the terms of this Agreement in the event that the Internal Revenue Service makes a determination that the first sentence of this paragraph is incorrect.

(c)            The Certificate Administrator shall report required WHFIT information using the accrual method, except to the extent the WHFIT Regulations specifically require a different method. The Certificate Administrator shall be under no obligation to determine whether any Certificateholder uses the cash or accrual method. The Certificate Administrator shall make available (via its website) WHFIT information to Certificateholders annually. In addition, the Certificate Administrator shall not be responsible or liable for providing subsequently amended, revised or updated information to any Certificateholder, unless requested by the Certificateholder.

 -410-

(d)            The Certificate Administrator shall not be liable for failure to meet the reporting requirements of the WHFIT Regulations nor for any penalties thereunder if such failure is due to: (i) the lack of reasonably necessary information being provided to the Certificate Administrator or (ii) incomplete, inaccurate or untimely information being provided to the Certificate Administrator. Each Certificateholder, by acceptance of its interest in such class of securities, will be deemed to have agreed to provide the Certificate Administrator with information regarding any sale of such securities, including the price, amount of proceeds and date of sale. Absent receipt of information regarding any sale of a Certificate, including the price, amount of proceeds and date of sale from the beneficial owner thereof or the Depositor, the Certificate Administrator shall assume there is no secondary market trading of WHFIT interests.

(e)       To the extent required by the WHFIT Regulations, the Certificate Administrator shall use reasonable efforts to publish on an appropriate website the CUSIP for the Class Z Certificates. The CUSIP so published will represent the Rule 144A CUSIP. The Certificate Administrator shall make reasonable good faith efforts to keep the website accurate and updated to the extent such CUSIP has been received. Absent the receipt of such CUSIP, the Certificate Administrator will use a reasonable identifier number in lieu of a CUSIP. The Certificate Administrator shall not be liable for investor reporting delays that result from the receipt of inaccurate or untimely CUSIP information.

(c)            During the Transfer Restriction Period, the HRR Certificates shall only be held as Definitive Certificates in the Third Party Purchaser Safekeeping Account by the Certificate Administrator (and the Holder of the HRR Certificates shall be registered on the Certificate Register), unless otherwise consented to by the Retaining Sponsor.

The Certificate Administrator (in the capacity described in this Section, the “Retained Interest Custodian”) hereby agrees to acquire and hold possession of the HRR Certificates on behalf of the Retaining Sponsor, and hereby expressly acknowledges that it holds such Certificates for and on behalf of the Retaining Sponsor.

Upon receipt by the Retained

 -416-

Interest Custodian of a written notice from the Retaining Sponsor (which notice shall also be provided to the Third-Party Purchaser) directing the further delivery of the HRR Certificates from the Retaining Sponsor (including any direction to reregister the HRR Certificates in the name of another Person), the Retained Interest Custodian shall, no sooner than two (2) Business Days of receipt thereof, promptly comply with such instructions of the Retaining Sponsor notwithstanding any direction to the contrary that may be received from any other party or Person.

Under no circumstances by virtue of safekeeping the HRR Certificates shall the Certificate Administrator (i) be obligated to bring legal action or institute proceedings against any person on behalf of the Holder of the HRR Certificates or the Retaining Sponsor or (ii) have any obligation to monitor, supervise or enforce the performance of any party under the related Credit Risk Retention Compliance Agreement. The Certificate Administrator shall be entitled to conclusively rely with no obligation to verify, confirm or otherwise monitor the accuracy of any information included in any written instructions provided in connection with the Third Party Purchaser Safekeeping Account and shall have no liability in connection therewith, other than with respect to the Certificate Administrator’s obligation to obtain the Retaining Sponsor’s consent prior to any release of the HRR Certificates. During the Transfer Restriction Period, the Certificate Administrator shall hold the Definitive Certificate representing the HRR Certificates at the location below, or any other location; provided the Certificate Administrator has given notice to the Holder of the HRR Certificates of such new location:

Wells Fargo Bank NA
Attn: Security Control and Transfer (SCAT) - MAC N9345-010

 -417-

policies and procedures. Any transfer of the HRR Certificates shall be subject to ARTICLE V of this Agreement.

In the event that the Retaining Sponsor notifies the Certificate Administrator that it has realized upon the HRR Certificates pledged to it under the Credit Risk Retention Compliance Agreement as a result of the Third Party Purchaser having failed to perform any of its Secured Obligations (as defined in the Credit Risk Retention Compliance Agreement) and upon written notice and instruction to a Responsible Officer of the Certificate Administrator at Wells Fargo Bank, National Association, 9062 Old Annapolis Road, Columbia Maryland 21045, Attention: Corporate Trust Services (CMBS) – CSAIL 2017-CX10 of the Retaining Sponsor’s election to realize upon the HRR Certificates under the Credit Risk Retention Compliance Agreement, the Certificate Administrator shall, in accordance with any authentication procedures as may be utilized by the Certificate Administrator, reasonably promptly register in the Certificate Register the Retaining Sponsor as the record owner of the HRR Certificates and fill in the Retaining Sponsor’s name in the HRR Certificate Power as assignee or as otherwise instructed by the Retaining Sponsor.

The Certificate Administrator shall be indemnified and held harmless for any release in connection with the preceding, in accordance with the terms set forth in Section 8.03. The Certificate Administrator shall have no further obligations with respect to the safekeeping of such released certificates.

Section 5.02     Form and Registration. No transfer of any Non-Registered Certificate shall be made unless that transfer is made pursuant to an effective registration statement under the Securities Act, and effective registration or qualification under applicable state securities laws, or is made in a transaction which does not require such registration or qualification. If a transfer (other than one by the Depositor to an Affiliate thereof or by the Initial Purchaser to Eightfold Real Estate Capital Fund V, L.P. or its Affiliate) is to be made in reliance upon an exemption from the Securities Act, and under the applicable state securities laws, then either:

(a)            Each Class of the Non-Registered Certificates (other than the HRR Certificates and Class R Certificates) sold to institutions that are non-United States Securities Persons in Offshore Transactions in reliance on Regulation S under the Act shall initially be

 -418-

represented by a temporary book-entry certificate in definitive, fully registered form without interest coupons, substantially in the applicable form set forth as an exhibit hereto (each a “Temporary Regulation S Book-Entry Certificate”), which shall be deposited on the Closing Date on behalf of the purchasers of the Non-Registered Certificates represented thereby with the Certificate Registrar, at its principal trust office, as custodian, for the Depository, and registered in the name of the Depository or the nominee of the Depository for the account of designated agents holding on behalf of Euroclear and/or Clearstream. Prior to the expiration of the 40-day period commencing on the later of the commencement of the offering and the Closing Date (the “Restricted Period”), beneficial interests in each Temporary Regulation S Book-Entry Certificate may be held only through Euroclear or Clearstream. After the expiration of the Restricted Period, a beneficial interest in a Temporary Regulation S Book-Entry Certificate may be exchanged for an interest in the related Regulation S Book-Entry Certificate in the applicable form set forth as an exhibit hereto in accordance with the procedures set forth in Section 5.03(f). During the Restricted Period, distributions due in respect of a beneficial interest in a Temporary Regulation S Book-Entry Certificate shall only be made upon delivery to the Certificate Registrar by Euroclear or Clearstream, as applicable, of a Non-U.S. Beneficial Ownership Certification. After the expiration of the Restricted Period, distributions due in respect of any beneficial interests in a Temporary Regulation S Book-Entry Certificate shall not be made to the holders of such beneficial interests unless exchange for a beneficial interest in the Regulation S Book-Entry Certificate of the same Class is improperly withheld or refused. The aggregate Certificate Balance of a Temporary Regulation S Book-Entry Certificate or a Regulation S Book-Entry Certificate may from time to time be increased or decreased by adjustments made on the records of the Certificate Registrar, as custodian for the Depository, as hereinafter provided.

On the Closing Date, the Certificate Administrator shall execute, the Authenticating Agent shall authenticate, and the Certificate Administrator shall deliver to the Certificate Registrar the Regulation S Book-Entry Certificates, which shall be held by the Certificate Registrar for purposes of effecting the exchanges contemplated by the preceding paragraph. Wells Fargo Bank, National Association is hereby initially appointed the Authenticating Agent with the power to act, on the Trustee’s behalf, in the authentication and delivery of the Certificates in connection with transfers and exchanges as herein provided. If Wells Fargo Bank, National Association is removed as Certificate Administrator, then Wells Fargo Bank, National Association shall be terminated as Authenticating Agent. If the Authenticating Agent is terminated, the Trustee shall appoint a successor authenticating agent, which may be the Trustee or an Affiliate thereof.

(b)           Certificates of each Class of Non-Registered Certificates (other than the HRR Certificates and other than the VRR Interest, the Y&L Towers VRR Interest and the Standard Highline VRR Interest following the conversion described in Section 5.03(i) hereof during the Transfer Restriction Period) offered and sold to Qualified Institutional Buyers in reliance on Rule 144A shall be represented by Rule 144A Book-Entry Certificates, which shall be deposited with the Certificate Registrar or an agent of the Certificate Registrar, as custodian for the Depository, and registered in the name of the Depository or a nominee of the Depository.

Upon notice of the occurrence of any of the events described in clause (i) or (ii) above with respect to any Certificates of a Class that are in the form of Book-Entry Certificates and upon surrender by the Depository of any Book-Entry Certificate of such Class and receipt from the Depository of instructions for re-registration, the Certificate Registrar shall issue Certificates of such Class in the form of Definitive Certificates (bearing, in the case of a Definitive Certificate issued for a Rule 144A Book-Entry Certificate, the same legends regarding transfer restrictions borne by such Book-Entry Certificate), and thereafter the Certificate Registrar shall recognize the Holders of such Definitive Certificates as Certificateholders under this Agreement. Unless and until Definitive Certificates are issued in respect of a Class of Book-Entry Certificates, beneficial ownership interests in such Class of Certificates will be maintained and transferred on the book entry records of the Depository and Depository Participants, and all references to actions by Holders of such Class of Certificates will refer to action taken by the Depository upon instructions received from the related registered Holders of Certificates through the Depository Participants in accordance with the Depository’s procedures and, except as otherwise set forth herein, all references herein to payments, notices, reports and statements to Holders of such Class of Certificates will refer to payments, notices, reports and statements to the Depository or its nominee as the registered Holder thereof, for distribution to the related registered Holders of Certificates through the Depository Participants in accordance with the Depository’s procedures.

 -424-

of a beneficial interest in such Temporary Regulation S Book-Entry Certificate, shall be exchanged after the Restricted Period, for interests in the Regulation S Book-Entry Certificate of the same Class. The Certificate Registrar shall effect such exchange by delivering to the Depository for credit to the respective accounts of such holders, a duly executed and authenticated Regulation S Book-Entry Certificate, representing the aggregate Certificate Balance of interests in the Temporary Regulation S Book-Entry Certificate initially exchanged for interests in the Regulation S Book-Entry Certificate.

Upon any exchange of interests in the Temporary Regulation S Book-Entry Certificate for interests in the Regulation S Book-Entry Certificate, the Certificate Registrar shall endorse the Temporary Regulation S Book-Entry Certificate to reflect the reduction in the Certificate Balance represented thereby by the amount so exchanged and shall endorse the Regulation S Book-Entry Certificate to reflect the corresponding increase in the amount represented thereby. Until so exchanged in full and except as provided therein, the Temporary Regulation S Book-Entry Certificate, and the Certificates evidenced thereby, shall in all respects be entitled to the same benefits under this Agreement as the Regulation S Book-Entry Certificate and Rule 144A Book-Entry Certificate authenticated and delivered hereunder.

Upon receipt by the Certificate Registrar, as registrar, at its office designated in Section 5.07, of (1) such Non-Book Entry Certificate, duly endorsed as provided herein, (2) instructions from such holder directing the Certificate Registrar, as registrar, to credit, or cause to be credited, a beneficial interest in the applicable Book-Entry Certificate equal to the portion of the Certificate Balance of the Non-Book Entry Certificate to be exchanged, such instructions to contain information regarding the participant account with the Depository to be credited with such increase and (3) a certificate in the form of Exhibit M hereto (in the event that the applicable Book-Entry Certificate is the Temporary Regulation S Book-Entry Certificate), in the form of Exhibit N hereto (in the event that the applicable Book-Entry Certificate is the Regulation S Book-Entry Certificate) or in the form of Exhibit O hereto (in the event that the applicable Book-Entry Certificate is the Rule 144A Book-Entry Certificate), then the Certificate Registrar, as registrar, shall cancel, or cause to be canceled, all or part of such Non-Book Entry Certificate, shall, if applicable, execute, authenticate and deliver to the transferor a new Non-Book Entry Certificate equal to the aggregate Certificate Balance of the portion retained by such transferor and shall instruct the Depository to increase, or cause to be increased, such Book-Entry Certificate by the aggregate Certificate Balance of the portion of the Non-Book Entry

Upon the written direction of the Depositor (which may be by email to cts.cmbs.bond.admin@wellsfargo.com) or its Affiliate, the Certificate Registrar shall execute any instrument as may be reasonably required by the Depository to effect such exchange.

(h)            Non-Book Entry Certificates on Initial Issuance Only. Subject to the issuance of Definitive Certificates, if and when permitted by Section 5.02(d), and subject to the issuance and transfer of the VRR Interest, the Y&L Towers VRR Interest and the Standard Highline VRR Interest in accordance with Section 5.03(i), no Non-Book Entry Certificate shall be issued to a transferee of an interest in any Rule 144A Book-Entry Certificate, Temporary Regulation S Book-Entry Certificate or Regulation S Book-Entry Certificate or to a transferee of a Non-Book Entry Certificate (or any portion thereof).

(i)             Transfers of VRR Interests, Y&L Towers VRR Interests or Standard Highline VRR Interests. At all times, if a Transfer of all or a portion of the VRR Interest, the Y&L Towers VRR Interest or the Standard Highline VRR Interest, as applicable, is to be made, then the Certificate Registrar shall refuse to register such transfer unless it receives (and, upon receipt, may conclusively rely upon) (i) a certification from such Certificateholder’s prospective Transferee substantially in the form attached hereto as Exhibit D-3, which such certification must be countersigned by the Retaining Sponsor and Depositor with a medallion stamp guarantee of the Retaining Sponsor and (ii) a certification from the Certificateholder desiring to effect such transfer substantially in the form attached hereto as Exhibit D-4, which such certification must be countersigned by the Retaining Sponsor and the Depositor with a medallion stamp guarantee of the Retaining Sponsor.

For the avoidance of doubt, other than at initial issuance, in no event shall a VRR Interest, the Y&L Towers VRR Interest or the Standard Highline VRR Interest be held as a Book-Entry Certificate during the Transfer Restriction Period; provided that, each Certificate representing the VRR Interest, the Y&L Towers VRR Interest or the Standard Highline VRR Interest, as applicable, shall on the Closing Date be issued in book-entry form and shall initially be held as a Book-Entry Certificate; however, upon initial issuance on the Closing Date, the Certificate Administrator is hereby instructed by the Depositor to exchange the Book-Entry Certificate(s) representing the VRR Interest, the Y&L Towers VRR Interest or the Standard Highline VRR Interest, as applicable, for a Definitive Certificate as soon as practicable after the Closing Date but no later than two (2) Business Days after the Closing Date and shall hold each Definitive Certificate evidencing the VRR Interest, the Y&L Towers VRR Interest or the Standard Highline VRR Interest, as applicable, in safekeeping pursuant to Section 5.02(e). Any attempted or purported transfer in violation of this Section 5.03(i) shall be null and void ab initio and shall vest no rights in any purported transferee and shall not relieve the transferor of any obligations with respect to the applicable Certificates.

(j)             Other Exchanges. In the event that a Book-Entry Certificate is exchanged for a Definitive Certificate, such Certificates may be exchanged only in accordance with such procedures as are substantially consistent with the provisions of subsections (c) through (f) above

 -426-

(including the certification requirements intended to ensure that such transfers comply with Rule 144A or Regulation S under the Act, at the case may be) and such other procedures as may from time to time be adopted by the Certificate Registrar.

(k)            Restricted Period. Prior to the termination of the Restricted Period with respect to the issuance of the Certificates, transfers of interests in the Temporary Regulation S Book-Entry Certificate to U.S. persons (as defined in Regulation S) shall be limited to transfers made pursuant to the provisions of subsection (e) above.

(l)             If Non-Registered Certificates are issued upon the transfer, exchange or replacement of Certificates bearing a restrictive legend relating to compliance with the Act, or if a request is made to remove such legend on Certificates, the Non-Registered Certificates so issued shall bear the restrictive legend, or such legend shall not be removed, as the case may be, unless there is delivered to the Certificate Registrar such satisfactory evidence, which may include an Opinion of Counsel that neither such legend nor the restrictions on transfer set forth therein are required to ensure that transfers thereof comply with the provisions of Rule 144A or Regulation S under the Act. Upon provision of such satisfactory evidence, the Certificate Registrar shall authenticate and deliver Certificates that do not bear such legend.

(m)           All Certificates surrendered for registration of transfer and exchange shall be canceled and subsequently destroyed by the Certificate Registrar in accordance with the Certificate Registrar’s customary procedures.

(n)           With respect to the ERISA Restricted Certificates, no sale, transfer, pledge or other disposition (other than any initial transfer to the Initial Purchaser or the Loan-Specific Initial Purchasers or with respect to the VRR Interest, NREC acting as a Retaining Party) of any such Certificate shall be made unless the Trustee and Certificate Administrator shall have received either (i) a representation letter from the proposed purchaser or transferee of such Certificate substantially in the form of Exhibit F-1 attached hereto, to the effect that such proposed purchaser or transferee is not and will not become (A) an employee benefit plan subject to the fiduciary responsibility provisions of ERISA or a plan subject to Section 4975 of the Code, or a governmental plan (as defined in Section 3(32) of ERISA), a church plan (as defined in Section 3(33) of ERISA) for which no election has been made under Section 410(d) of the Code or any other plan subject to any federal, state or local law (“Similar Law”) which is, to a material extent, similar to the foregoing provisions of ERISA or the Code (each, a “Plan”) or (B) a person acting on behalf of or using the assets of any such Plan (including an entity whose underlying assets include Plan assets by reason of investment in the entity by such Plan and the application of Department of Labor Regulation § 2510.3-101, as modified by Section 3(42) of ERISA), other than an insurance company using the assets of its general account under circumstances whereby the purchase and holding of such Certificates by such insurance company would be exempt from the prohibited transaction provisions of ERISA and the Code under Sections I and III of Prohibited Transaction Class Exemption 95-60 (or, in the case of a Plan subject to Similar Law, would not result in a non-exempt violation of Similar Law) or (ii) if such Certificate which may be held only by a person not described in clauses (A) or (B) above, is presented for registration in the name of a purchaser or transferee that is any of the foregoing, an Opinion of Counsel in form and substance satisfactory to the Trustee and Certificate Administrator and the Depositor to the effect that the acquisition and holding of such Certificate by such purchaser or transferee will

Each Certificate Owner of an ERISA Restricted Certificate shall be deemed to represent that it is not and will not become a Person specified in clauses (i)(A) or (i)(B) above. Any transfer, sale, pledge or other disposition of any ERISA Restricted Certificates that would constitute or result in a prohibited transaction under ERISA, Section 4975 of the Code or any Similar Law, or would otherwise violate the provisions of this Section 5.03(n) shall be deemed absolutely null and void ab initio, to the extent permitted under applicable law.

In addition, each beneficial owner of a Certificate or any interest therein that is a Plan subject to Title I of ERISA or Section 4975 of the Code (an “ERISA Plan”), including any fiduciary purchasing Certificates on behalf of an ERISA Plan (“Plan Fiduciary”), will be deemed to have represented by its acquisition of such Certificates that:

Reg. 20,997). If these regulations are revoked, repealed or no longer effective, these representations shall be deemed to be no longer in effect.

(o)            No Class V1-Z, Class V2-Z, Class R or Class Z Certificate may be purchased by or transferred to any prospective purchaser or transferee that is or will be a Plan, or any person acting on behalf of a Plan or using the assets of a Plan (including an entity whose underlying assets include Plan assets by reason of investment in the entity by such Plan and the application of Department of Labor Regulation § 2510.3-101, as modified by Section 3(42) of ERISA) to purchase such Class V1-Z, Class V2-Z, Class R or Class Z Certificate.

Any attempted or purported transfer in violation of these transfer restrictions shall be null and void ab initio and shall vest no rights in any purported transferee and shall not relieve the transferor of any obligations with respect to the applicable Certificates.

Each Person who has or acquires any Residual Ownership Interest shall be deemed by the acceptance or acquisition of such Residual Ownership Interest to have agreed to be bound by the following provisions and the rights of each Person acquiring any Residual Ownership Interest are expressly subject to the following provisions:

(i)           Each Person acquiring or holding any Residual Ownership Interest shall be a Permitted Transferee and shall not acquire or hold such Residual Ownership Interest as

 -429-

agent (including a broker, nominee or other middleman) on behalf of any Person that is not a Permitted Transferee. Any such Person shall promptly notify the Certificate Registrar of any change or impending change in its status (or the status of the beneficial owner of such Residual Ownership Interest) as a Permitted Transferee. Any acquisition described in the first sentence of this Section 5.03(o) by a Person who is not a Permitted Transferee or by a Person who is acting as an agent of a Person who is not a Permitted Transferee shall be void ab initio and of no effect, and the immediately preceding owner who was a Permitted Transferee shall be restored to registered and beneficial ownership of the Residual Ownership Interest as soon and as fully as possible.

(ii)          No Residual Ownership Interest may be Transferred, and no such Transfer shall be registered in the Certificate Register, without the express written consent of the Certificate Registrar, and the Certificate Registrar shall not recognize the Transfer, and such proposed Transfer shall not be effective, without such consent with respect thereto. In connection with any proposed Transfer of any Residual Ownership Interest, the Certificate Registrar shall, as a condition to such consent, (x) require the proposed transferee to deliver, and the proposed transferee shall deliver to the Certificate Registrar and to the proposed transferor, an affidavit in substantially the form attached as Exhibit D-1 (a “Transferee Affidavit”) of the proposed transferee (A) that such proposed transferee is a Permitted Transferee and (B) stating that (1) the proposed transferee historically has paid its debts as they have come due and intends to do so in the future, (2) the proposed transferee understands that, as the holder of a Residual Ownership Interest, it may incur liabilities in excess of cash flows generated by the residual interest, (3) the proposed transferee intends to pay taxes associated with holding the Residual Ownership Interest as they become due, (4) the proposed transferee will not cause income with respect to the Residual Ownership Interest to be attributable to a foreign permanent establishment or fixed base, within the meaning of an applicable income tax treaty, of such proposed transferee or any other U.S. Tax Person, (5) the proposed transferee will not transfer the Residual Ownership Interest to any Person that does not provide a Transferee Affidavit or as to which the proposed transferee has actual knowledge that such Person is not a Permitted Transferee or is acting as an agent (including a broker, nominee or other middleman) for a Person that is not a Permitted Transferee, and (6) the proposed transferee expressly agrees to be bound by and to abide by the provisions of this Section 5.03(o) and (y) other than in connection with the initial issuance of a Class R Certificate, require a statement from the proposed transferor substantially in the form attached as Exhibit D-2 (the “Transferor Letter”), that the proposed transferor has no actual knowledge that the proposed transferee is not a Permitted Transferee and has no actual knowledge or reason to know that the proposed transferee’s statements in its Transferee Affidavit are false.

(iii)        Notwithstanding the delivery of a Transferee Affidavit by a proposed transferee under clause (ii) above, if a Responsible Officer of the Certificate Registrar has actual knowledge that the proposed transferee is not a Permitted Transferee, no Transfer to such proposed transferee shall be effected and such proposed Transfer shall not be registered on the Certificate Register; provided, however, that the Certificate Registrar shall not be required to conduct any independent investigation to determine whether a proposed transferee is a Permitted Transferee. Upon notice to the Certificate Registrar

 -430-

that there has occurred a Transfer to any Person that is a Disqualified Organization or an agent thereof (including a broker, nominee or middleman) in contravention of the foregoing restrictions, and in any event not later than sixty (60) days after a request for information from the transferor of such Residual Ownership Interest or such agent, the Certificate Registrar agrees to furnish to the Internal Revenue Service and the transferor of such Residual Ownership Interest or such agent such information necessary to the application of Section 860E(e) of the Code as may be required by the Code, including, but not limited to, the present value of the total anticipated excess inclusions with respect to such Class R Certificate (or portion thereof) for periods after such Transfer. At the election of the Certificate Registrar, the Certificate Registrar may charge a reasonable fee for computing and furnishing such information to the transferor or to such agent referred to above; provided, however, that such Persons shall in no event be excused from furnishing such information.

(p)            The Class R Certificates may only be transferred to and owned by Qualified Institutional Buyers.

(q)           Other than with respect to a transfer made pursuant to the last paragraph of Section 5.01(c), if a transfer of the HRR Certificates is to be made, then the Certificate Registrar shall refuse to register such transfer unless it receives (and, upon receipt, may conclusively rely upon) (i) a certification from such Certificateholder’s prospective transferee substantially in the form attached hereto as Exhibit D-5, which such certification must be countersigned by the Retaining Sponsor and Depositor with a medallion stamp guarantee of the Retaining Sponsor and (ii) a certification from the Certificateholder desiring to effect such transfer substantially in the form attached hereto as Exhibit D-6, which such certification must be countersigned by the Retaining Sponsor and Depositor with a medallion stamp guarantee of the Retaining Sponsor. Upon receipt of the foregoing certifications, the Certificate Registrar shall, subject to Section 5.01(c) and Section 5.03, reflect the HRR Certificates in the name of the prospective transferee. For the avoidance of doubt, in no event shall the HRR Certificates be held as a Global Certificate during the Transfer Restriction Period.

(r)             Notwithstanding any other provision of this Agreement, the Certificate Administrator shall comply with all federal withholding requirements respecting payments to Certificateholders and other payees of interest or original issue discount that the Certificate Administrator reasonably believes are applicable under the Code. The consent of Certificateholders or payees shall not be required for such withholding, and the Certificateholders shall be required to provide the Certificate Administrator with such forms and other such information reasonably required by the Certificate Administrator.

Such amounts shall be deemed to have been distributed to such Persons for all purposes of this Agreement.

In connection with the issuance of any new Certificate under this Section 5.04, the Certificate Registrar may require the payment of a sum sufficient to cover any expenses (including the fees and expenses of the Certificate Registrar) connected therewith.

Once a Holder has cast its vote, the vote may be changed or retracted on or before the vote deadline. Any changes or retractions shall be communicated by the Certificateholder to the Certificate Administrator in writing on a ballot. After the vote deadline has passed, votes may not be changed or retracted by any Holder unless the Holder wishing to change or retract its vote holds a sufficient portion of the Voting Rights such that the Holder, by its vote alone, could approve or deny the proposition subject to a vote without taking into consideration the votes cast by any other Holder. Transferees or purchasers of any Class of Certificates are subject to and shall be bound by all votes of Holders initiated or conducted prior to its acquisition of such Certificate.

Promptly after the votes are tabulated, the Certificate Administrator shall prepare a notice announcing the results of the vote. Such notice shall include the percentage of Voting Rights in favor of the proposition, the percentage against the proposition and the percentage abstaining. In addition, the notice will announce whether the proposition has been adopted by Certificateholders. The notice shall be distributed in accordance with the methods described in Section 5.10(a) above. The Certificate Administrator shall also include such notice on the Form 10-D prepared in connection with the distribution period that corresponds with the date such notice is distributed. All vote tabulations shall be final and the Certificate Administrator shall not, absent manifest error, re-tabulate the votes or conduct a new vote for the same proposition.

(d)       Any and all reasonable expenses incurred by the Certificate Administrator in connection with administering any vote shall be borne by the Trust. The Certificate Administrator is under no obligation to advise Holders about the matter being voted on or answer questions other than process-related questions regarding the administration of the vote.

(e)       If any party to this Agreement believes a vote of Certificateholders is needed for some matter related to the administration of the Trust that is not specifically

 -440-

contemplated herein, such party may request the Certificate Administrator to conduct a vote and the Certificate Administrator will conduct the requested vote in accordance with these procedures. Unless specifically provided herein, all such votes require a majority of Certificateholders to carry a proposition.

(b)         The Depositor, the Master Servicer, the Special Servicer, the Operating Advisor and the Asset Representations Reviewer each may be merged or consolidated with or into any Person, or transfer all or substantially all of its assets (which may be limited to all or substantially all of its assets related to commercial mortgage loan servicing or commercial mortgage surveillance, as the case may be) to any Person, in which case any Person resulting from any merger or consolidation to which the Depositor, the Master Servicer, the Special Servicer, the Operating Advisor, or the Asset Representations Reviewer shall be a party, or any Person succeeding to the business of the Depositor, the Master Servicer, the Special Servicer, the Operating Advisor, or the Asset Representations Reviewer, shall be the successor of the Depositor, the Master Servicer, the Special Servicer, the Operating Advisor, or the Asset Representations Reviewer (such Person, in the case of the Master Servicer or the Special Servicer, in each of the foregoing cases, the “Surviving Entity”), as the case may be, hereunder, without the execution or filing of any paper (other than an assumption agreement wherein the successor shall agree to perform the obligations of and serve as the Depositor, the Master Servicer, the Special Servicer, the Operating Advisor, or the Asset Representations Reviewer, as the case may be, in accordance with the terms of this Agreement) or any further act on the part of any of the parties hereto, anything herein to the contrary notwithstanding; provided, however, that with respect to such merger, consolidation or succession, Rating Agency Confirmation is received from each Rating Agency with respect to the Classes of Certificates and, with respect to

 -447-

any class of Serviced Companion Loan Securities, a confirmation is received from each applicable rating agency that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates as described in Section 3.25); provided, further, that if the Master Servicer, the Special Servicer, the Operating Advisor or the Asset Representations Reviewer enters into a merger and the Master Servicer, the Special Servicer, the Operating Advisor or the Asset Representations Reviewer, as applicable, is the Surviving Entity under applicable law, the Master Servicer, the Special Servicer, the Operating Advisor or the Asset Representations Reviewer, as applicable, shall not, as a result of the merger, be required to provide a Rating Agency Confirmation with respect to ratings of the Classes of Certificates or, with respect to any class of Serviced Companion Loan Securities, a confirmation of the rating agencies that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings; provided, further, that for so long as the Trust, and, with respect to any Companion Loan included as part of the trust in a related Other Securitization, is subject to the reporting requirements of the Exchange Act, if the Master Servicer, the Special Servicer, the Operating Advisor or the Asset Representations Reviewer notifies the Depositor in writing (a “Merger Notice”) of any such merger, consolidation, conversion or other change in form, and the Depositor or the depositor in such Other Securitization, as the case may be, notifies the Master Servicer, the Special Servicer, the Operating Advisor or the Asset Representations Reviewer, as applicable, in writing that the Depositor or the depositor in such Other Securitization, as the case may be, has discovered that such successor entity has not complied with its Exchange Act reporting obligations under any other commercial mortgage loan securitization (and specifically identifying the instance of noncompliance), then it shall be an additional condition to such succession that the Depositor or the depositor in such Other Securitization, as the case may be, shall have consented (which consent shall not be unreasonably withheld or delayed) to such successor entity.

If the conditions to the provisions in the second preceding sentence are not met, the Trustee may terminate, and if the conditions set forth in the third proviso of the third preceding sentence are not met the Trustee shall terminate, the applicable Surviving Entity’s servicing of the Mortgage Loans and the Trust Subordinate Companion Loans pursuant hereto, such termination to be effected in the manner set forth in Section 7.01.

The Depositor, the Master Servicer (including in its capacity as Companion Paying Agent), the Special Servicer, the Operating Advisor, the Asset Representations Reviewer and any partner, director, officer, shareholder, member, manager, employee or agent of the Depositor, the Master Servicer (including in its capacity as Companion Paying Agent), the Special Servicer, the Operating Advisor or the Asset Representations Reviewer may rely on any document of any kind which, prima facie, is properly executed and submitted by any Person respecting any matters arising hereunder. The Depositor, the Master Servicer (including in its capacity as Companion Paying Agent), the Special Servicer, the Asset Representations Reviewer and the Operating Advisor and any partner, director, officer, shareholder, member, manager, employee or agent of any of the foregoing shall be indemnified and held harmless by the Trust against any and all claims, losses, penalties, fines, forfeitures, reasonable legal fees and related costs, judgments, and any other costs, liabilities, fees and expenses incurred in connection with, or related to, this Agreement, the Mortgage Loans, the Companion Loans or the Certificates (including any costs of enforcement of its indemnity), other than any loss, liability or expense: (i) specifically required to be borne thereby pursuant to the terms hereof; (ii) incurred in connection with any breach of a representation or warranty made by it herein; (iii) incurred by reason of bad faith, willful misconduct or negligence in the performance of its obligations or duties hereunder, or by reason of negligent disregard of such obligations or duties; or (iv) in the case of the Depositor and any of its partners, directors, officers, shareholders, members, managers, employees and agents, incurred in connection with any violation by any of them of any state or federal securities law.

Each of the Master Servicer (including in its capacity as Companion Paying Agent), the Special Servicer, the Asset Representations Reviewer and the Operating Advisor conclusively may rely on, and shall be protected in acting or refraining from acting upon, any resolution, officer’s certificate, certificate of auditors or any other certificate, statement, instrument, opinion, report, notice, request, consent, order, financial statement, agreement, appraisal, bond or other document (in electronic or paper format) as contemplated by and in accordance with this Agreement and reasonably believed or in good faith believed by the Master Servicer (including in its capacity as Companion

 -449-

Paying Agent), the Special Servicer, the Asset Representations Reviewer or the Operating Advisor to be genuine and to have been signed or presented by the proper party or parties and each of them may consult with counsel, in which case any written advice of counsel or Opinion of Counsel shall be full and complete authorization and protection with respect to any action taken or suffered or omitted by it hereunder in good faith and in accordance with such advice or Opinion of Counsel.

(b)         None of the Depositor, the Master Servicer (including in its capacity as Companion Paying Agent), the Special Servicer, the Operating Advisor and the Asset Representations Reviewer shall be under any obligation to appear in, prosecute or defend any legal or administrative action (whether in equity or at law), proceeding, hearing or examination that is not incidental to its respective duties under this Agreement or which in its opinion may involve it in any expense or liability not recoverable from the Trust; provided, however, that each of the Depositor, the Master Servicer, the Special Servicer, the Operating Advisor or the Asset Representations Reviewer may in its discretion undertake any such action, proceeding, hearing or examination that it may deem necessary or desirable in respect to this Agreement and the rights and duties of the parties hereto and the interests of the Certificateholders (and, in the case of any Serviced Whole Loan, the rights of the Certificateholders and the holders of a Serviced Companion Loan (as a collective whole) taking into account the subordinate or pari passu nature of such Serviced Companion Loan); provided, however, that if a Serviced Whole Loan and/or the holder of any related Companion Loan are involved, such expenses, costs and liabilities will be payable out of funds related to the applicable Serviced Whole Loan in accordance with the related Intercreditor Agreement and will also be payable out of the other funds in the Collection Account if amounts on deposit with respect to such Serviced Whole Loan are insufficient therefor. If any such expenses, costs or liabilities relate to a Mortgage Loan or Companion Loan, then any subsequent recovery on that Mortgage Loan or Companion Loan, as applicable, will be used to reimburse the Trust for any amounts advanced for the payment of such expenses, costs or liabilities. In such event, the legal expenses and costs of such action, proceeding, hearing or examination and any liability resulting therefrom shall be expenses, costs and liabilities of the Trust, and the Depositor, the Master Servicer (including in its capacity as Companion Paying Agent), the Special Servicer, the Asset Representations Reviewer and the Operating Advisor shall be entitled to be reimbursed therefor out of amounts attributable to the Mortgage Loans or the Companion Loan on deposit in the Collection Account (including, without duplication, any subaccount thereof), as provided by Section 3.05(a)(xii).

 -458-

Notwithstanding anything herein to the contrary, with respect to any Servicing Shift Mortgage Loan, the Loan-Specific Directing Certificateholder shall, pursuant to the related Co-Lender Agreement, exercise any consent and consultation rights, and rights to provide direction to the Master Servicer or Special Servicer, of the “Directing Certificateholder” with respect to such Mortgage Loan as provided for in this Agreement until the Servicing Shift Securitization Date.

Notwithstanding anything herein to the contrary, no such advice, direction or objection by, from or on the part of the Directing Certificateholder, Operating Advisor or Risk Retention Consultation Party contemplated in the preceding paragraphs of this Section 6.08(a), may require or cause the Master Servicer or Special Servicer to violate any provision of any Mortgage Loan or related Intercreditor Agreement, applicable law, this Agreement, or the REMIC Provisions (and, with respect to a Serviced Whole Loan, subject to the rights of the holders of the related Companion Loan), including without limitation the obligation of the Master Servicer and the Special Servicer to act in accordance with the Servicing Standard, or expose the Master Servicer, the Special Servicer, the Certificate Administrator, the Operating Advisor, the Asset Representations Reviewer, the Trust or the Trustee to liability, or materially expand the scope of the responsibilities of the Master Servicer or the Special Servicer, as applicable, hereunder or cause the Master Servicer or the Special Servicer, as applicable, to act, or fail to act, in a manner which in the reasonable judgment of the Master Servicer or the Special Servicer, as the case may be, is not in the best interests of the Certificateholders. In the event the Special Servicer or the Master Servicer, as applicable, determines that a refusal to consent by the Directing Certificateholder or any advice from the Operating Advisor, the Directing Certificateholder or the Risk Retention Consultation Party, would cause the Special Servicer or Master Servicer, as applicable, to violate the terms of any Mortgage Loan, applicable law or this Agreement, including without limitation, the Servicing Standard, the Special Servicer or the Master Servicer, as applicable, shall disregard such refusal to consent or advise and notify the Operating Advisor, the Directing Certificateholder or the Risk Retention Consultation Party,

 -459-

respectively, and the Trustee and the Rating Agencies of its determination, including a reasonably detailed explanation of the basis therefor. The taking of, or refraining from taking, any action by the Master Servicer or the Special Servicer in accordance with the direction of or approval of the Directing Certificateholder and the Operating Advisor or the approval of the Risk Retention Consultation Party that does not violate the terms of any Mortgage Loan, Trust Subordinate Companion Loan, applicable law or the Servicing Standard or any other provisions of this Agreement, will not result in any liability on the part of the Master Servicer or the Special Servicer.

The Directing Holder shall have no liability to the Trust or the Certificateholders for any action taken, or for refraining from the taking of any action, or for errors in judgment; provided, however, that the Directing Holder shall not be protected against any liability to a Controlling Class Certificateholder that would otherwise be imposed by reason of willful misconduct, bad faith or negligence in the performance of duties owed to the Controlling Class Certificateholders or by reason of reckless disregard of obligations or duties owed to the Controlling Class Certificateholders. By its acceptance of a Certificate, each Certificateholder acknowledges and agrees that the Directing Holder may take actions that favor the interests of one or more Classes of Certificates including the Holders of the Controlling Class over other Classes of the Certificates, and that the Directing Certificateholder may have special relationships and interests that conflict with those of Holders of some Classes of the Certificates, that the Directing Holder may act solely in the interests of the Holders of the Controlling Class, including the Holders of the Controlling Class, that the Directing Holder does not have any duties or liability to the Holders of any Class of Certificates other than the Controlling Class, that the Directing Holder shall not be liable to any Certificateholder, by reason of its having acted solely in the interests of the Holders of the Controlling Class, and that the Directing Holder shall have no liability whatsoever for having so acted, and no Certificateholder may take any action whatsoever against the Directing Holder or any director, officer, employee, agent or principal thereof for having so acted.

The Risk Retention Consultation Party shall have no liability to the Trust or the Certificateholders for any action taken, or for refraining from the taking of any action, or for errors in judgment; provided, however, that the Risk Retention Consultation Party shall not be protected against any liability to a Holder of an VRR Interest, Y&L Towers VRR Interest or Standard Highline VRR Interest, as applicable, that would otherwise be imposed by reason of willful misconduct, bad faith or gross negligence in the performance of duties owed to the Holders of the VRR Interest, Y&L Towers VRR Interest or Standard Highline VRR Interest, as applicable, or by reason of reckless disregard of obligations or duties owed to the Holders of the VRR Interest, Y&L Towers VRR Interest or Standard Highline VRR Interest, as applicable. By its acceptance of a Certificate, each Certificateholder acknowledges and agrees that the Risk Retention Consultation Party may take actions that favor the interests of one or more Classes of the Certificates including the Holders of an VRR Interest, Y&L Towers VRR Interest or Standard Highline VRR Interest, as applicable, over other Classes of the Certificates, and that the Risk Retention Consultation Party may have special relationships and interests that conflict with those of Holders of some Classes of the Certificates, that the Risk Retention Consultation Party may act solely in the interests of the Holders of an VRR Interest, Y&L Towers VRR Interest or Standard Highline VRR Interest, that the Risk Retention Consultation Party does not have any duties or liability to the Holders of any Class of Certificates other than the VRR Interest, Y&L

 -460-

Towers VRR Interest or Standard Highline VRR Interest, that the Risk Retention Consultation Party shall not be liable to any Certificateholder, by reason of its having acted solely in the interests of the Holder of the VRR Interest, Y&L Towers VRR Interest or Standard Highline VRR Interest, and that the Risk Retention Consultation Party shall have no liability whatsoever for having so acted, and no Certificateholder may take any action whatsoever against the Risk Retention Consultation Party or any director, officer, employee, agent or principal thereof for having so acted.

Any Non-Serviced Whole Loan Controlling Holder, with respect to a Non-Serviced Whole Loan, shall have no liability to the Trust or the Certificateholders for any action taken, or for refraining from the taking of any action, or for errors in judgment. By its acceptance of a Certificate, each Certificateholder acknowledges and agrees that any such Non-Serviced Whole Loan Controlling Holder, with respect to the related Non-Serviced Whole Loan, may take actions that favor the interests of one or more classes of the certificates issued under the related Non-Serviced PSA including the Holders of the controlling class under such Non-Serviced PSA over other Classes of the Certificates, and that such Non-Serviced Whole Loan Controlling Holder, with respect to such Non-Serviced Whole Loan, may have special relationships and interests that conflict with those of Holders of some Classes of the Certificates, that such Non-Serviced Whole Loan Controlling Holder, with respect to such Non-Serviced Whole Loan, may act solely in the interests of the Holders of the controlling class under the related Non-Serviced PSA, that such Non-Serviced Whole Loan Controlling Holder, shall not be liable to any Certificateholder, by reason of its having acted solely in the interests of the Holders of the controlling class under the related Non-Serviced PSA, and that such Non-Serviced Whole Loan Controlling Holder, with respect to such Non-Serviced Whole Loan, shall have no liability whatsoever for having so acted, and no Certificateholder may take any action whatsoever against such Non-Serviced Whole Loan Controlling Holder, with respect to such Non-Serviced Whole Loan, or any director, officer, employee, agent or principal thereof for having so acted.

(b)         Notwithstanding anything to the contrary contained herein (i) after the occurrence and during the continuance of a Control Termination Event (and at any time with respect to any Excluded Loan with respect to the Directing Holder or, if the Directing Holder is the Directing Certificateholder, the Holder of the majority of the Controlling Class), the Directing Holder shall have no right to consent to or direct any action taken or not taken by any party to this Agreement; (ii) after the occurrence and during the continuance of a Control Termination Event but prior to the occurrence and continuance of a Consultation Termination Event, the Directing Holder shall remain entitled to receive any notices, reports or information to which it is entitled pursuant to this Agreement, and the Special Servicer and any other applicable party shall consult with the Directing Holder (other than with respect to any Excluded Loan as to such party) to the extent set forth herein in connection with any action to be taken or refrained from taking; and (iii) after the occurrence and continuance of a Consultation Termination Event, the Directing Holder (at any time with respect to any Excluded Loan as to either such party) shall have no direction, consultation or consent rights hereunder and no right to receive any notices, reports or information (other than notices, reports or information required to be delivered to all Certificateholders) or any other rights as Directing Holder.

For the avoidance of doubt, with respect to any Specially Serviced Loan, the Risk Retention Consultation Party shall at all times remain entitled to receive any notices, reports or

 -461-

information to which it is entitled pursuant to this Agreement, and the Special Servicer and any other applicable party shall consult with the Risk Retention Consultation Party (other than with respect to any Excluded Loan as to such party) to the extent set forth herein in connection with any action to be taken or refrained from taking.

(c)         Prior to the occurrence and continuance of an Operating Advisor Consultation Event, the Special Servicer shall provide each Major Decision Reporting Package to the Operating Advisor promptly after the Special Servicer receives the Directing Holder’s approval or deemed approval of such Major Decision Reporting Package; provided, however, that with respect to any non-Specially Serviced Loan no Major Decision Reporting Package shall be required to be delivered prior to the occurrence and continuance of an Operating Advisor Consultation Event. During the continuance of an Operating Advisor Consultation Event (whether or not a Control Termination Event is continuing), the Special Servicer will be required to provide each Major Decision Reporting Package to the Operating Advisor simultaneously with the Special Servicer’s written request for the Operating Advisor’s input regarding the related Major Decision (which written request and Major Decision Reporting Package may be delivered in one notice), as set forth under Section 6.08. With respect to any particular Major Decision and/or related Major Decision Reporting Package or any Asset Status Report required to be delivered by the Master Servicer or the Special Servicer to the Operating Advisor, the Master Servicer or the Special Servicer, as applicable, shall make available to the Operating Advisor a servicing officer with relevant knowledge regarding the Mortgage Loan and such Major Decision and/or Asset Status Report in order to address reasonable questions that the Operating Advisor may have relating to, among other things, such Major Decision and/or Asset Status Report.

In addition, if an Operating Advisor Consultation Event has occurred and is continuing, the Special Servicer will also be required to consult with the Operating Advisor in connection with any proposed Major Decision (and any other actions which otherwise require consultation with the Operating Advisor) and consider alternative actions recommended by the Operating Advisor, in respect thereof, provided that such consultation is on a non-binding basis. In the event that the Special Servicer receives no response from the Operating Advisor within ten (10) days following the later of (i) its written request for input (which request is required to include the related Major Decision Reporting Package) on any required consultation and (ii) delivery of all such additional information reasonably requested by the Operating Advisor that is in the possession of the Special Servicer related to the subject matter of such consultation, the Special Servicer shall not be obligated to consult with the Operating Advisor on the specific matter; provided, however, that the failure of the Operating Advisor to respond on any specific matters shall not relieve the Special Servicer from its obligation to consult with the Operating Advisor on any future matter with respect to the applicable Mortgage Loan or Trust Subordinate Companion Loan or any other Mortgage Loan. Notwithstanding anything herein to the contrary, with respect to any Excluded Loan (regardless of whether an Operating Advisor Consultation Event has occurred and is continuing), the Special Servicer shall consult with the Operating Advisor, on a non-binding basis, in connection with the related transactions involving proposed Major Decisions that it is processing and consider alternative actions recommended by the Operating Advisor, in respect thereof, in accordance with the procedures set forth in this Section 6.08 for consulting with the Operating Advisor.

 -462-

In connection with the Directing Certificateholder’s or Operating Advisor’s right to consent or consult with respect to a Major Decision, as applicable, if the Special Servicer determines that action is necessary to protect the related Mortgaged Property or the interests of the Certificateholders from potential harm if such action is not taken, or if a failure to take any such action at such time would be inconsistent with Accepted Servicing Practices, the Special Servicer may take actions with respect to the related Mortgaged Property before the expiration of the applicable period for the Operating Advisor or Directing Certificateholder to respond as described in this section, if the Special Servicer reasonably determines in accordance with Accepted Servicing Practices that failure to take such actions before the expiration of such period would materially adversely affect the interest of the Certificateholders, and the Special Servicer has made a reasonable effort to contact the Operating Advisor or the Directing Certificateholder, as applicable.

In addition, (i) for so long as no Consultation Termination Event is continuing, with respect to any Specially Serviced Loan (other than any Non-Serviced Mortgage Loan or any applicable Excluded Loan) and (ii) during the continuance of a Consultation Termination Event, with respect to any Mortgage Loan (other than any Non-Serviced Mortgage Loan or applicable Excluded Loan), the Special Servicer will also be required to consult with the Risk Retention Consultation Party in connection with any Major Decision that it is processing (and such other matters that are subject to consultation rights of the Risk Retention Consultation Party pursuant to this Agreement) and to consider alternative actions recommended by the Risk Retention Consultation Party in respect of such Major Decision; provided that such consultation is on a non-binding basis. In the event the Master Servicer or the Special Servicer, as applicable, receives no response from the Risk Retention Consultation Party within 10 days following the later of (i) the Special Servicer’s, written request for input (which request is required to include the related Major Decision Reporting Package) on any required consultation and (ii) delivery of all such additional information reasonably requested by the Risk Retention Consultation Party and reasonably available to the Special Servicer related to the subject matter of such consultation, the Master Servicer or the Special Servicer, as applicable, will not be obligated to consult with the Risk Retention Consultation Party on the specific matter; provided, however, that the failure of the Risk Retention Consultation Party to respond shall not relieve the Master Servicer or the Special Servicer, as applicable, using reasonable efforts to consult with the Risk Retention Consultation Party on any future matters with respect to the applicable Mortgage Loan or Serviced Whole Loan or any other Mortgage Loan.

After the occurrence and during the continuance of a Consultation Termination Event, the Directing Certificateholder shall have no consultation or consent rights hereunder and shall have no right to receive any notices, reports or information (other than notices, reports or information required to be delivered to all Certificateholders) or any other rights as Directing Certificateholder. However, the Directing Certificateholder shall maintain the right to exercise its Voting Rights for the same purposes as any other Certificateholder.

Except as otherwise expressly set forth in this Agreement, Wells Fargo Bank, National Association acting in any particular capacity hereunder will not be deemed to be imputed with knowledge of (a) Wells Fargo Bank, National Association, acting in a capacity that is unrelated to the transactions contemplated by this Agreement, or (b) Wells Fargo Bank, National Association, acting in any

From and after the receipt by the Affected Party of such written notice except as otherwise provided in this Article VII, all authority and power of the Affected Party under this Agreement, whether with respect to the Certificates (other than as a Holder of any Certificate) or the Mortgage Loans and the Trust Subordinate Companion Loans or otherwise, shall pass to and be vested in the Trustee with respect to a termination of the Master Servicer or the Special Servicer pursuant to and under this Section 7.01, and, without limitation, the Trustee is hereby authorized and empowered to execute and deliver, on behalf of and at the expense of the Affected Party, as attorney-in-fact or otherwise, any and all documents and other instruments, and to do or accomplish all other acts or things necessary or appropriate to effect the purposes of such notice of termination, whether to complete the transfer and endorsement or assignment of the Mortgage Loans or the Trust Subordinate Companion Loans and related documents, or otherwise.

(c)         If the Master Servicer receives notice of termination under Section 7.01(a)(viii) solely due to a Servicer Termination Event under Section 7.01(a)(viii) or (a)(ix), the Master Servicer shall have a forty-five (45) day period after such notice in which to find a successor master servicer qualified to act as Master Servicer hereunder in accordance with Section 6.03 and Section 7.02 and to which the Master Servicer can sell its rights to service the Mortgage Loans and the Trust Subordinate Companion Loans under this Agreement. During such forty-five (45) day period the Master Servicer may continue to serve as Master Servicer hereunder. In the event that the Master Servicer is unable, within such forty-five (45) day period, to cause a qualified successor master servicer to assume the duties of the Master Servicer hereunder, then and in such event, the Trustee shall assume the obligations of the Master Servicer hereunder.

Notwithstanding Section 7.01(a)(viii), if any Servicer Termination Event on the part of the Special Servicer shall occur and be continuing that affects the Holder of a Serviced Pari Passu Companion Loan, then, so long as the Special Servicer is not otherwise terminated, the Holder of such Serviced Pari Passu Companion Loan or the Other Trustee appointed under the related Other Pooling and Servicing Agreement, as applicable, shall be entitled to direct the Trustee to terminate the Special Servicer with respect to the related Serviced Pari Passu Whole Loan. The Special Servicer appointed to replace the Special Servicer with respect to a Serviced Pari Passu Mortgage Loan cannot at any time be (without the prior written consent of the holder of such Serviced Pari Passu Companion Loan) the person (or Affiliate thereof) that was terminated at the direction of the holder of the related Serviced Pari Passu Companion Loan. Any the Special Servicer under this paragraph shall meet the eligibility requirements of Section 7.02 and the eligibility requirements of the related Other Pooling and Servicing Agreement, and the appointment thereof shall comply with the provisions of Section 7.02. Any appointment of a replacement special servicer in accordance with this paragraph shall be subject to the receipt of Rating Agency Confirmation and confirmation from the rating agencies that such appointment or replacement will not result in the downgrade, withdrawal or qualification of the then-current ratings of any class of any related Serviced Companion Loan Securities (provided that such rating agency confirmation may be considered satisfied in the same manner

 -468-

as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant to Section 3.25).

If any Servicer Termination Event on the part of the Master Servicer affects only the Y&L Towers Trust Subordinate Companion Loan, the Master Servicer may not be terminated as the Master Servicer of the Mortgage Pool, but the Y&L Towers Directing Holder, as applicable (prior to the occurrence and continuance of a Y&L Towers Trust Subordinate Control Termination Event) will be entitled to direct the Master Servicer to appoint a sub-servicer solely with respect to the related Whole Loan (or if the Yorkshire & Lexington Towers Whole Loan is currently being sub-serviced, to replace the current sub-servicer, but only if such sub-servicer is in default under the related sub-servicing agreement).

If any Servicer Termination Event on the part of the Master Servicer affects only the Standard Highline Trust Subordinate Companion Loan, the Master Servicer may not be terminated as the Master Servicer of the Mortgage Pool, but the Standard Highline Directing Holder (prior to the occurrence and continuance of a Standard Highline Non-Trust Junior Subordinate Control Termination Event, a Standard Highline Non-Trust Senior Subordinate Control Termination Event or a Standard Highline Trust Subordinate Control Termination Event, as applicable) will be entitled to direct the Master Servicer to appoint a sub-servicer solely with respect to The Standard Highline NYC Whole Loan (or if The Standard Highline NYC Whole Loan is currently being sub-serviced, to replace the current sub-servicer, but only if such sub-servicer is in default under the related sub-servicing agreement).

(d)       Subject to the right of the Operating Advisor to recommend the termination of the Special Servicer and recommend a Qualified Replacement Special Servicer and the right of the applicable Certificateholders to approve the replacement of the Special Servicer with such Qualified Replacement Special Servicer pursuant to this Section 7.01(d), and subject to the rights of the holder of a related AB Subordinate Companion Loan (other than a Trust Subordinate Companion Loan pursuant to the related Intercreditor Agreement, at any time prior to the occurrence and continuance of a Control Termination Event and other than with respect to any Excluded Loan with respect to the Directing Certificateholder or the Holder of the majority of the Controlling Class, the Directing Certificateholder shall be entitled to terminate the rights (subject to Section 3.11 and Section 6.04) and obligations of the Special Servicer under this Agreement, with or without cause, upon ten (10) Business Days’ notice to the Special Servicer, the Master Servicer, the Certificate Administrator, the Trustee and the Operating Advisor; such termination to be effective upon the appointment of a successor special servicer meeting the requirements of this Section 7.01(d), provided that, with respect to a Servicing Shift Whole Loan, the ten (10) Business Days’ notice set forth in this Section 7.01(d) shall not apply to the related Loan-Specific Directing Certificateholder’s right to terminate the Special Servicer’s rights and obligations under this Agreement without cause with respect to such Servicing Shift Whole Loan pursuant to the terms of the related Co-Lender Agreement. Upon a termination of the Special Servicer, the Directing Certificateholder (other than with respect to any Excluded Loan with respect to the Directing Certificateholder or the Holder of the majority of the Controlling Class) shall designate a successor special servicer; provided, however, that (i) such successor will meet the requirements set forth in Section 7.02, (ii) each Rating Agency delivers Rating Agency Confirmation and, in the case of any class of any Serviced Companion Loan Securities the applicable rating agencies deliver a confirmation that such action will not

 -469-

result in the downgrade, withdrawal or qualification of its then-current ratings (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant to Section 3.25) and (iii) no replacement of the Special Servicer shall be effective until the Certificate Administrator shall have filed any required Form 8-K pursuant to Section 11.07 hereof and any other Form 8-K filings have been completed with respect to any related Companion Loan.

After the occurrence and during the continuance of a Control Termination Event that relates to any Mortgage Loan (but for so long as no Control Termination Event is continuing with respect to the Yorkshire & Lexington Towers Whole Loan or The Standard Highline NYC Whole Loan, as applicable) or Serviced Whole Loan, upon (a) the written direction of (a) Holders of Pooled Principal Balance Certificates evidencing not less than 25% of the Pooled Voting Rights (taking into account the application of any Appraisal Reduction Amounts to notionally reduce the Certificate Balances pursuant to Section 4.05 hereof) of the Pooled Principal Balance Certificates requesting a vote to replace the Special Servicer (other than with respect to the Yorkshire & Lexington Towers Whole Loan or The Standard Highline NYC Whole Loan, as applicable) with a new special servicer designated in such written direction, (b) payment by such Holders to the Certificate Administrator of the reasonable fees and expenses (including any legal fees and any Rating Agency fees and expenses) to be incurred by the Certificate Administrator in connection with administering such vote and which shall not be additional expenses of the Trust and (c) delivery by such Holders to the Certificate Administrator and Trustee of Rating Agency Confirmation from each Rating Agency (which Rating Agency Confirmation shall be obtained at the expense of such Holders), the Certificate Administrator shall promptly post notice to all Certificateholders of such request on the Certificate Administrator’s Website in accordance with Section 3.13(b) and concurrently by mail, and conduct the solicitation of votes of all Pooled Certificates in such regard, which vote shall occur within one hundred eighty (180) days of the posting of such notice. Upon the written direction of (a) Holders of Pooled Principal Balance Certificates evidencing at least 66-2/3% of a Pooled Certificateholder Quorum or (b) Holders of Pooled Voting Rights of each Class of Pooled Non-Reduced Certificates evidencing more than 66 2/3% of the Pooled Voting Rights of each of Class of Pooled Non-Reduced Certificates, the Trustee shall terminate all of the rights and obligations of the Special Servicer (other than with respect to the Yorkshire & Lexington Towers Whole Loan and The Standard Highline NYC Whole Loan, as applicable) under this Agreement and appoint the successor special servicer (which must be a Qualified Replacement Special Servicer) designated by such Pooled Certificateholders.

After the occurrence and during the continuance of a Control Termination Event that relates to any Mortgage Loan (and for so long as a Control Termination Event is continuing with respect to the Yorkshire & Lexington Towers Whole Loan or The Standard Highline NYC Whole Loan, as applicable), upon (a) the written direction of Holders of Principal Balance Certificates evidencing not less than 25% of the Voting Rights (taking into account the application of any Cumulative Appraisal Reduction Amounts to notionally reduce the Certificate Balances pursuant to Section 4.05 hereof) of the Principal Balance Certificates requesting a vote to replace such Special Servicer with a new special servicer designated in such written direction, (b) payment by such Holders to the Certificate Administrator of the reasonable fees and expenses (including any legal fees and any Rating Agency fees and expenses) to be incurred by the

 -470-

Certificate Administrator in connection with administering such vote and which will not be additional expenses of the Trust and (c) delivery by such Holders to the Certificate Administrator and Trustee of Rating Agency Confirmation from each Rating Agency (which Rating Agency Confirmation shall be obtained at the expense of such Holders), the Certificate Administrator shall promptly post notice to all Certificateholders of such request on the Certificate Administrator’s Website in accordance with Section 3.13(b) and concurrently by mail, and conduct the solicitation of votes of all Certificates in such regard, which requisite affirmative votes shall be received within one hundred eighty (180) days of the posting of such notice. Upon the written direction of (a) Holders of Principal Balance Certificates evidencing at least 66 2/3% of a Certificateholder Quorum or (b) Holders of Non-Reduced Certificates evidencing more than 66 2/3% of the aggregate Voting Rights of each Class of Non-Reduced Certificates, the Trustee shall terminate all of the rights and obligations of such Special Servicer under this Agreement and appoint the successor special servicer (which must be a Qualified Replacement Special Servicer) designated by such Certificateholders.

The Certificate Administrator shall include on each Distribution Date Statement a statement that each Certificateholder may (i) access such notices via the Certificate Administrator’s Website and (ii) register to receive electronic mail notifications when such notices are posted thereon. Notwithstanding the foregoing, the Certificateholders’ direction to replace the Special Servicer will not apply to a Serviced AB Whole Loan unless, with respect to a Pooled Serviced Whole Loan, an AB Control Appraisal Period is continuing, with respect to the Yorkshire & Lexington Towers Whole Loan, a Y&L Towers Control Termination Event is continuing and with respect to The Standard Highline NYC Whole Loan, a Standard Highline Control Termination Event is continuing. With respect to The Standard Highline NYC Whole Loan, the Standard Highline Non-Trust Junior Subordinate Companion Loan, will have the right, prior to the occurrence and continuance of a Standard Highline Non-Trust Junior Subordinate Companion Loan Control Appraisal Period, to replace the Special Servicer with respect to The Standard Highline NYC Whole Loan. After a Standard Highline Non-Trust Junior Subordinate Companion Loan Control Appraisal Period and prior to a Standard Highline Non-Trust Senior Subordinate Companion Loan Control Appraisal Period, the Standard Highline Non-Trust Senior Subordinate Companion Loan will have the right to replace the Special Servicer with respect to The Standard Highline NYC Whole Loan. The Standard Highline Trust Subordinate Companion Loan will have the right, after the occurrence and continuance of a Standard Highline Non-Trust Senior Subordinate Companion Loan Control Appraisal Period and prior to the occurrence and continuance of a Standard Highline Trust Subordinate Companion Loan Control Termination Event, to replace the Special Servicer solely with respect to The Standard Highline NYC Whole Loan.

The parties hereto acknowledge that, notwithstanding anything to the contrary contained in this section, in accordance with the related Intercreditor Agreement, if a servicer termination event on the part of a Non-Serviced Special Servicer under a Non-Serviced PSA remains unremedied and affects the holder of the related Non-Serviced Mortgage Loan, and the related Non-Serviced Special Servicer has not otherwise been terminated, the holder of the related Non-Serviced Mortgage Loan (or the Trustee (or, prior to a Control Termination Event, the Trustee, acting at the direction of the Directing Certificateholder)) will be entitled to direct the related Non-Serviced Trustee to terminate the related Non-Serviced Special Servicer solely with respect to the related Non-Serviced Whole Loan. The appointment (or replacement) of a

 -471-

special servicer with respect to a Non-Serviced Whole Loan, as applicable, will in any event be subject to Rating Agency Confirmation from each Rating Agency. A replacement special servicer will be selected by the related Non-Serviced Trustee or, prior to a control termination event (or similarly defined term) under the related Non-Serviced PSA, by the related Non-Serviced Whole Loan Controlling Holder; provided, however, that any successor special servicer appointed to replace the special servicer with respect to such Non-Serviced Whole Loan cannot at any time be the Person (or an Affiliate thereof) that was terminated at the direction of the holder of such Non-Serviced Mortgage Loan, without the prior written consent of the Directing Certificateholder.

If at any time the Operating Advisor determines, in its sole discretion exercised in good faith, that (i) the Special Servicer is not performing its duties as required hereunder or is otherwise not acting in accordance with the Servicing Standard, and (ii) the replacement of the Special Servicer would be in the best interest of the Certificateholders as a collective whole, then the Operating Advisor shall deliver to the Trustee and the Certificate Administrator, with a copy to the Special Servicer, a written report in the form of Exhibit W attached hereto (which form may be modified or supplemented from time to time to cure any ambiguity or error or to incorporate any additional information, subject to compliance of such form with the terms and provisions of this Agreement; provided, further, that in no event shall the information or any other content included in such written report contravene any provision of this Agreement) detailing the reasons supporting its recommendation (provided that the Operating Advisor will not be permitted to recommend the replacement of the Special Servicer for any Whole Loan so long as the holder of the related Companion Loan is the Directing Holder under the related Intercreditor Agreement) (along with relevant information justifying its recommendation) and recommending a suggested replacement special servicer, which shall be a Qualified Replacement Special Servicer. In such event, the Certificate Administrator shall promptly post notice to all applicable Certificateholders of such recommendation and the related report on the Certificate Administrator’s Website in accordance with Section 3.13(b), and by mail conduct the solicitation of votes of all applicable Certificates in such regard. Upon (i) the affirmative vote of Voting Rights evidencing at least a majority of a Quorum (which, this purpose is the Holders that (i) evidence at least 20% of the Voting Rights (taking into account the application of any Appraisal Reduction Amounts to notionally reduce the respective Certificate Balances) of all Principal Balance Certificates on an aggregate basis, and (B) consist of at least three (3) Certificateholders, or the Certificate Owners that are not Risk Retention Affiliated with each other) and (ii) receipt of Rating Agency Confirmation from each Rating Agency with respect to the termination of the Special Servicer and the appointment of a successor special servicer recommended by the Operating Advisor following satisfaction of the foregoing clause (i), the Trustee (upon receipt of written confirmation from the Certificate Administrator, if the Certificate Administrator and the Trustee are different entities) shall (i) terminate all of the rights and obligations of the Special Servicer under this Agreement and appoint such successor Special Servicer and (ii) promptly notify such outgoing Special Servicer of the effective date of such termination. The reasonable out-of-pocket costs and expenses (including reasonable legal fees and expenses of outside counsel) associated with obtaining such Rating Agency Confirmations and administering such vote(s) and the Operating Advisor’s identification of a Qualified Replacement Special Servicer shall be an additional expense of the Trust. In the event that the Trustee does not receive the affirmative vote of at least a majority of the quorum described in clause (i) of the preceding sentence within 180 days of the posting of the notice to the Certificate Administrator’s Website,

 -472-

then the Trustee shall have no obligation to remove the Special Servicer. Prior to the appointment of any replacement special servicer, such replacement special servicer shall have agreed to succeed to the obligations of the Special Servicer under this Agreement and to act as the Special Servicer’s successor hereunder. In the event the Special Servicer is terminated pursuant to this Section 7.01(d), the Directing Holder may not subsequently reappoint such terminated Special Servicer or any Risk Retention Affiliate thereof.

No penalty or fee shall be payable to the terminated Special Servicer with respect to any termination pursuant to this Section 7.01(d). All costs of any such termination made by the Directing Certificateholder without cause shall be paid by the Holders of the Controlling Class.

For the avoidance of doubt, the indemnification of the Operating Advisor in Section 6.04 shall include, subject to the limitations set forth in Section 6.04, any action or claim arising from, or relating to, the Operating Advisor’s determination under this Section 7.01(d) (regarding removal of the Special Servicer), or the result of the vote of the Pooled Certificateholders or Loan-Specific Certificateholders, as applicable (regarding removal of the Special Servicer).

(e)         The Master Servicer and the Special Servicer shall, as the case may be, from time to time, take all such reasonable actions as are required by it in accordance with the related Servicing Standard in order to prevent the Certificates from being placed on “watch” status or downgraded due to servicing or special servicing, as applicable, concerns by any Rating Agency. In no event shall the remedy for a breach of the foregoing covenant extend beyond termination pursuant to Section 7.01(a)(viii) and Section 7.01(a)(ix) and the resulting operation of Section 7.01(a)(viii) and (c). The operation of this subsection (e) shall not be construed to limit the effect of Section 7.01(a)(viii) and Section 7.01(a)(ix).

(f)          Notwithstanding the foregoing, (1) if any Servicer Termination Event on the part of the Master Servicer affects a Serviced Companion Loan, any related Serviced Companion Noteholder or the rating on any class of certificates backed, wholly or partially, by any Serviced Companion Loan Securities, and if the Master Servicer is not otherwise terminated, or (2) if a Servicer Termination Event on the part of the Master Servicer affects only a Serviced Companion Loan, any related Serviced Companion Noteholder or the rating on any class of certificates backed, wholly or partially, by any Serviced Companion Loan Securities, then the Master Servicer may not be terminated by or at the direction of such Serviced Companion Noteholder or the holders of any certificates backed, wholly or partially, by such Serviced Companion Loan, but upon the written direction of such Serviced Companion Noteholder, the Master Servicer shall be required to appoint a sub-servicer that will be responsible for servicing the related Serviced Whole Loan.

(g)         Notwithstanding anything to the contrary contained in this Section 7.01, with respect to any Excluded Special Servicer Loan, if any, the related Special Servicer shall resign as Special Servicer of that Excluded Special Servicer Loan. Prior to the occurrence and continuance of a Control Termination Event, if the applicable Excluded Special Servicer Loan is not also an Excluded Loan as to the Directing Holder or, if the Directing Holder is the Directing Certificateholder, the Holder of the majority of the Controlling Class, the Directing Holder shall

 -473-

select an Excluded Special Servicer, as successor to the resigning Special Servicer, for the related Excluded Special Servicer Loan in accordance with this Agreement. After the occurrence and during the continuance of a Control Termination Event or if the Directing Certificateholder or the majority Controlling Class Certificateholder on its behalf fails to make the selection contemplated by the prior sentence within ten (10) Business Days or if at any time the applicable Excluded Special Servicer Loan is also an Excluded Loan as to the Directing Holder or, if the Directing Holder is the Directing Certificateholder, the Holder of the majority of the Controlling Class, the resigning Special Servicer shall use reasonable efforts to select the related Excluded Special Servicer. The Special Servicer shall not have any liability with respect to the actions or inactions of the applicable Excluded Special Servicer or with respect to the identity of the applicable Excluded Special Servicer so long as, on the date of the appointment, such appointment of such Excluded Special Servicer meets the criteria of this Agreement. It shall be a condition to any such appointment that (i) the Rating Agencies confirm that the appointment would not result in a qualification, downgrade or withdrawal of any of their then-current ratings of the Certificates and each NRSRO hired to provide ratings with respect to any Serviced Companion Loan Securities makes the equivalent confirmation, (ii) the related Excluded Special Servicer is a Qualified Replacement Special Servicer and (iii) the related Excluded Special Servicer delivers to the Depositor and the Certificate Administrator and any applicable Other Depositor and Other Certificate Administrator, the information, if any, required under Item 6.02 of Form 8-K pursuant to the Exchange Act regarding itself in its role as Excluded Special Servicer.

If at any time the Special Servicer is no longer a Borrower Party (including, without limitation, as a result of the related Mortgaged Property becoming an REO Property) with respect to an Excluded Special Servicer Loan, (1) the related Excluded Special Servicer shall resign, (2) the related Mortgage Loan or Serviced Whole Loan shall no longer be an Excluded Special Servicer Loan, (3) the Special Servicer shall become the Special Servicer again for such related Mortgage Loan or Serviced Whole Loan and (4) the Special Servicer shall be entitled to all special servicing compensation with respect to such Mortgage Loan or Serviced Whole Loan earned during such time on and after such Mortgage Loan or Serviced Whole Loan is no longer an Excluded Special Servicer Loan; provided, however, that other than with respect to an Excluded Loan, the related Excluded Special Servicer shall not be required to resign if the Directing Holder determines that such Excluded Special Servicer may continue to serve as special servicer for the applicable Excluded Special Servicer Loan.

The applicable Excluded Special Servicer shall perform all of the obligations of the Special Servicer for the related Excluded Special Servicer Loan and shall be entitled to all special servicing compensation with respect to such Excluded Special Servicer Loan earned during such time as the related Mortgage Loan or Serviced Whole Loan is an Excluded Special Servicer Loan (provided that the Special Servicer shall remain entitled to all other special servicing compensation with respect all Mortgage Loans and Serviced Whole Loans that are not Excluded Special Servicer Loans during such time).

If a Servicing Officer of the Master Servicer, a related Excluded Special Servicer, or the Special Servicer, as applicable, has actual knowledge that a Mortgage Loan is no longer an Excluded Loan, an Excluded Controlling Class Loan or an Excluded Special Servicer Loan, as applicable, the Master Servicer, the related Excluded Special Servicer or the Special Servicer, as

 -474-

applicable, shall provide prompt written notice thereof to each of the other parties to this Agreement.

Section 7.02     Trustee to Act; Appointment of Successor. On and after the time the Master Servicer or the Special Servicer, as the case may be, either resigns pursuant to subsection (a) of the first sentence of Section 6.05 or receives a notice of termination for cause pursuant to Section 7.01(a)(viii), and provided that no acceptable successor has been appointed within the time period specified in Section 7.01(c), the Trustee shall be the successor to such party, until such successor to the Master Servicer or the Special Servicer, as applicable, is appointed as provided in this Section 7.02 or by the Directing Holder as provided in Section 7.01(d), as applicable, in all respects in its capacity as Master Servicer or the Special Servicer, as applicable, under this Agreement and the transactions set forth or provided for herein and shall be subject to, and have the benefit of, all of the rights, (subject to Section 3.11 and Section 6.04) benefits, responsibilities, duties, liabilities and limitations on liability relating thereto and that arise thereafter placed on or for the benefit of the Master Servicer or the Special Servicer, as applicable, by the terms and provisions hereof; provided, however, that any failure to perform such duties or responsibilities caused by the terminated party’s failure under Section 7.01 to provide information or moneys required hereunder shall not be considered a default by such successor hereunder. The appointment of a successor master servicer shall not affect any liability of the predecessor Master Servicer which may have arisen prior to its termination as Master Servicer, and the appointment of a successor special servicer shall not affect any liability of the predecessor Special Servicer which may have arisen prior to its termination as Special Servicer. The Trustee in its capacity as successor to the Master Servicer or the Special Servicer, as the case may be, shall not be liable for any of the representations and warranties of the Master Servicer or the Special Servicer, respectively, herein or in any related document or agreement, for any acts or omissions of the predecessor master servicer or special servicer or for any losses incurred by the predecessor Master Servicer pursuant to Section 3.06 hereunder, nor shall the Trustee be required to purchase any Mortgage Loan or Trust Subordinate Companion Loan hereunder solely as a result of its obligations as successor master servicer or special servicer, as the case may be. Subject to Section 3.11, as compensation therefor, the Trustee as successor master servicer shall be entitled to the Servicing Fees and all fees relating to the Mortgage Loans, the Companion Loans that the Master Servicer would have been entitled to if the Master Servicer had continued to act hereunder, including but not limited to any income or other benefit from any Permitted Investment pursuant to Section 3.06, and subject to Section 3.11, and the Trustee as successor to the Special Servicer shall be entitled to the Special Servicing Fees to which the Special Servicer would have been entitled if the Special Servicer had continued to act hereunder. Should the Trustee succeed to the capacity of the Master Servicer or the Special Servicer, as the case may be, the Trustee shall be afforded the same standard of care and liability as the Master Servicer or the Special Servicer, as applicable, hereunder notwithstanding anything in Section 8.01 to the contrary, but only with respect to actions taken by it in its role as successor master servicer or successor special servicer, as the case may be, and not with respect to its role as Trustee hereunder. Notwithstanding the above, the Trustee may, if it shall be unwilling to act as successor to the Master Servicer or the Special Servicer, as applicable, or shall, if it is unable to so act, or if the Trustee is not approved as a servicer by each Rating Agency, or if the Directing Holder ((i) prior to the occurrence and continuance of a Control Termination Event and (ii) other than with respect to any Excluded Loan with respect to the Directing Holder or, if the Directing Holder is the Directing Certificateholder, the Holder of

the majority of the Controlling Class) or the Holders of Certificates entitled to at least (a) 25% of the Voting Rights in the case of the Master Servicer, (b) 25% of the Pooled Voting Rights in the case of the Special Servicer (other than with respect to the Yorkshire & Lexington Towers Whole Loan or The Standard Highline NYC Whole Loan), (c) 25% of the Y&L Towers Voting Rights in the case of the Special Servicer with respect to the Yorkshire & Lexington Towers Whole Loan or (d) 25% of the Standard Highline Voting Rights in the case of the Special Servicer with respect to The Standard Highline NYC Whole Loan so request in writing to the Trustee, promptly appoint, or petition a court of competent jurisdiction to appoint, any established mortgage loan servicing institution or other entity which meets the criteria set forth in Section 6.05 and otherwise herein, as the successor to the Master Servicer or the Special Servicer, as applicable, hereunder in the assumption of all or any part of the responsibilities, duties or liabilities of the Master Servicer or the Special Servicer hereunder. No appointment of a successor to the Master Servicer or the Special Servicer hereunder shall be effective until (i) the assumption in writing by the successor to the Master Servicer or the Special Servicer of all its responsibilities, duties and liabilities hereunder that arise thereafter, (ii) upon receipt of Rating Agency Confirmation from each Rating Agency and confirmation of the applicable rating agencies that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings of any Serviced Companion Loan Securities, if any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant to Section 3.25), (iii) which appointment has been approved (prior to the occurrence and continuance of a Control Termination Event) by the Directing Holder, such approval not to be unreasonably withheld and (iv) the Certificate Administrator shall have filed any required Form 8-K pursuant to Section 11.07 and any other Form 8-K filings have been completed with respect to any related Companion Loan. Pending appointment of a successor to the Master Servicer or the Special Servicer hereunder, unless the Trustee shall be prohibited by law from so acting, the Trustee shall act in such capacity as herein above provided. In connection with such appointment and assumption of a successor to the Master Servicer or the Special Servicer as described herein, the Trustee may make such arrangements for the compensation of such successor out of payments on the Mortgage Loans and the Trust Subordinate Companion Loans as it and such successor shall agree; provided, however, that no such compensation with respect to a successor master servicer or successor special servicer, as the case may be, shall be in excess of that permitted the terminated Master Servicer or Special Servicer, as the case may be, hereunder. The Trustee, the Master Servicer or the Special Servicer (whichever is not the terminated party) and such successor shall take such action, consistent with this Agreement, as shall be necessary to effectuate any such succession. Any costs and expenses associated with the transfer of the servicing function (other than with respect to a termination without cause) under this Agreement shall be borne by the predecessor Master Servicer or Special Servicer, as applicable. If such predecessor Master Servicer or Special Servicer (as the case may be) has not reimbursed the party requesting such termination or the successor master servicer or special servicer for such expenses within 90 days after the presentation of reasonable documentation, such expense shall be reimbursed by the Trust; provided that the terminated Master Servicer or Special Servicer shall not thereby be relieved of its liability for such expenses. If and to the extent that the terminated Master Servicer or Special Servicer has not reimbursed such costs and expenses, the party requesting such termination shall have an affirmative obligation to take all reasonable actions to collect such expenses on behalf of the Trust. In the event of a termination

 -476-

without cause, such costs and expenses shall be borne by the party requesting such termination, or as otherwise set forth herein; provided that the Certificate Administrator and the Trustee shall not bear any such costs and expenses. For the avoidance of doubt, if the Trustee is terminating the Master Servicer or Special Servicer in accordance with this Agreement at the direction of any party or parties permitted to direct the Trustee to so terminate the Master Servicer or the Special Servicer pursuant to this Agreement, the Trustee shall not have any liability for such expenses pursuant to this paragraph.

Section 7.03     Notification to Certificateholders. (a) Upon any resignation of the Master Servicer or the Special Servicer pursuant to Section 6.05, any termination of the Master Servicer or the Special Servicer pursuant to Section 7.01 or any appointment of a successor to the Master Servicer or the Special Servicer pursuant to Section 7.02, the Certificate Administrator shall give prompt written notice thereof to Certificateholders at their respective addresses appearing in the Certificate Register.

(b)         Not later than the later of (i) sixty (60) days after the occurrence of any event which constitutes or, with notice or lapse of time or both, would constitute a Servicer Termination Event and (ii) five (5) days after the Certificate Administrator would be deemed to have notice of the occurrence of such an event in accordance with Section 8.02(vii), the Certificate Administrator shall transmit by mail to the Depositor and all Certificateholders (and, if a Serviced Whole Loan is affected, the related Serviced Companion Noteholder) notice of such occurrence, unless such default shall have been cured.

Section 7.04     Waiver of Servicer Termination Events. A Servicer Termination Event may be waived by the Certificateholders evidencing not less than (a) 66-2/3% of the Voting Rights in the case of the Master Servicer, (b) 66-2/3% of the Pooled Voting Rights in the case of the Special Servicer (other than with respect to the Yorkshire & Lexington Towers Whole Loan and The Standard Highline NYC Whole Loan), (c) 66-2/3% of the Y&L Towers Voting Rights in the case of the Special Servicer with respect to the Yorkshire & Lexington Towers Whole Loan or (d) 66-2/3% of the Standard Highline Voting Rights in the case of the Special Servicer with respect to The Standard Highline NYC Whole Loan, within twenty (20) days of the receipt of notice from the Certificate Administrator of the occurrence of such Servicer Termination Event; provided, however, that (1) a Servicer Termination Event under clause (i) or (ii) of Section 7.01(a) may be waived only by all of the Certificateholders of the affected Classes and (2) a Servicer Termination Event under clause (iii) or (ix) of Section 7.01(a) relating to Exchange Act reporting may be waived only with the consent of the Depositor, together with (in the case of each of clauses (1) and (2) of this sentence) the consent of each Serviced Companion Noteholder, if any, that is affected by such Servicer Termination Event. Upon any such waiver of a Servicer Termination Event, such Servicer Termination Event shall cease to exist and shall be deemed to have been remedied for every purpose hereunder. Upon any such waiver of a Servicer Termination Event by Certificateholders, the Trustee and the Certificate Administrator shall be entitled to recover all costs and expenses incurred by it in connection with enforcement action taken with respect to such Servicer Termination Event prior to such waiver from the Trust. No such waiver shall extend to any subsequent or other Servicer Termination Event or impair any right consequent thereon except to the extent expressly so waived. Notwithstanding any other provisions of this Agreement, for purposes of waiving any Servicer Termination Event pursuant to this Section 7.04, Certificates registered in the name of

 -477-

the Depositor or any Affiliate of the Depositor shall be entitled to the same Voting Rights with respect to the matters described above as they would if any other Person held such Certificates.

Section 7.05     Trustee as Maker of Advances. In the event that the Master Servicer fails to fulfill its obligations hereunder to make any Advances and such failure remains uncured, the Trustee shall perform such obligations (x) within five (5) Business Days following such failure by the Master Servicer with respect to Servicing Advances resulting in a Servicer Termination Event under Section 7.01(a)(iii) hereof to the extent a Responsible Officer of the Trustee has actual knowledge of such failure with respect to such Servicing Advances and (y) by noon, New York City time, on the related Distribution Date with respect to P&I Advances pursuant to the Certificate Administrator’s notice of failure pursuant to Section 4.03(a) unless such failure has been cured. With respect to any such Advance made by the Trustee, the Trustee shall succeed to all of the Master Servicer’s rights with respect to Advances hereunder, including, without limitation, the Master Servicer’s rights of reimbursement and interest on each Advance at the Reimbursement Rate, and rights to determine that a proposed Advance is a Nonrecoverable P&I Advance or Servicing Advance, as the case may be, (without regard to any impairment of any such rights of reimbursement caused by such Master Servicer’s default in its obligations hereunder); provided, however, that if Advances made by the Trustee and the Master Servicer shall at any time be outstanding, or any interest on any Advance shall be accrued and unpaid, all amounts available to repay such Advances and the interest thereon hereunder shall be applied entirely to the Advances outstanding to the Trustee, until such Advances shall have been repaid in full, together with all interest accrued thereon, prior to reimbursement of the Master Servicer for such Advances. The Trustee shall be entitled to conclusively rely on any notice given with respect to a Nonrecoverable Advance hereunder.

A copy of such instrument shall be delivered to the Master Servicer, the Special Servicer and the Certificateholders by the Depositor. Except as described in the following sentence, the terminated or removed Trustee or Certificate Administrator, as applicable, shall bear all reasonable costs and expenses in connection with its termination or removal. If no successor trustee or certificate administrator shall have been so appointed and have accepted appointment within ninety (90) days after the giving of such notice of removal, the removed Trustee or Certificate Administrator may petition any court of competent jurisdiction for the appointment of a successor trustee or certificate administrator, as applicable, at the expense of the Trust.

Further, the resigning Trustee or Certificate Administrator, as the case may be, shall pay all costs and expenses associated with the transfer of its duties.

If the same party is acting as Trustee and Certificate Administrator pursuant to this Agreement, any removal of either such party in its capacity as Trustee or Certificate

Section 8.08     Successor Trustee or Certificate Administrator. (a) Any successor trustee or certificate administrator appointed as provided in Section 8.07 shall execute, acknowledge and deliver to the Depositor, the Master Servicer, the Special Servicer and to its predecessor Trustee or Certificate Administrator an instrument accepting such appointment hereunder, and thereupon the resignation or removal of the predecessor Trustee or Certificate Administrator shall become effective and such successor trustee or certificate administrator without any further act, deed or conveyance, shall become fully vested with all the rights, powers, duties and obligations of its predecessor hereunder, with the like effect as if originally named as Trustee or Certificate Administrator herein. The predecessor Trustee shall deliver to the successor trustee all Mortgage Files and related documents and statements held by it hereunder (other than any Mortgage Files at the time held on its behalf by a Custodian, which Custodian, at Custodian’s option shall become the agent of the successor trustee), and the Depositor, the Master Servicer, the Special Servicer and the predecessor Trustee shall execute and deliver such instruments and do such other things as may reasonably be required to more fully and certainly vest and confirm in the successor trustee all such rights, powers, duties and obligations, and to enable the successor trustee to perform its obligations hereunder.

(b)            No successor trustee or successor certificate administrator shall, as applicable, accept appointment as provided in this Section 8.08 unless at the time of such acceptance such successor trustee or successor certificate administrator, as applicable, shall be eligible under the provisions of Section 8.06.

(c)            Upon acceptance of appointment by a successor trustee or successor certificate administrator as provided in this Section 8.08, the Master Servicer shall deliver notice of the succession of such Trustee or Certificate Administrator, as applicable, to the Depositor and the Certificateholders.

 -488-

further act on the part of any of the parties hereto, anything herein to the contrary notwithstanding. The Certificate Administrator shall post such notice to the Certificate Administrator’s Website in accordance with Section 3.13(b) and shall provide notice of such event to the Master Servicer, the Special Servicer, the Depositor and the 17g-5 Information Provider, which shall post such notice to the 17g-5 Information Provider’s Website in accordance with Section 3.13(c).

Section 8.10     Appointment of Co-Trustee or Separate Trustee. (a) Notwithstanding any other provisions hereof, at any time, for the purpose of meeting any legal requirements of any jurisdiction in which any part of the Trust Fund or property securing the same may at the time be located, the Master Servicer and the Trustee acting jointly shall have the power and shall execute and deliver all instruments to appoint one or more Persons approved by the Trustee to act as co-trustee or co-trustees, jointly with the Trustee, or separate trustee or separate trustees, of all or any part of the Trust Fund, and to vest in such Person or Persons, in such capacity, such title to the Trust, or any part thereof, and, subject to the other provisions of this Section 8.10, such powers, duties, obligations, rights and trusts as the Master Servicer and the Trustee may consider necessary or desirable. If the Master Servicer shall not have joined in such appointment within fifteen (15) days after the receipt by it of a request to do so, or in case a Servicer Termination Event shall have occurred and be continuing, the Trustee alone shall have the power to make such appointment. No co-trustee or separate trustee hereunder shall be required to meet the terms of eligibility as a successor trustee under Section 8.06 hereunder and no notice to Holders of Certificates of the appointment of co-trustee(s) or separate trustee(s) shall be required under Section 8.08.

(b)            In the case of any appointment of a co-trustee or separate trustee pursuant to this Section 8.10, all rights, powers, duties and obligations conferred or imposed upon the Trustee shall be conferred or imposed upon and exercised or performed by the Trustee and such separate trustee or co-trustee jointly, except to the extent that under any law of any jurisdiction in which any particular act or acts are to be performed (whether as Trustee hereunder or as successor to the Master Servicer or the Special Servicer hereunder), the Trustee shall be incompetent or unqualified to perform such act or acts, in which event such rights, powers, duties and obligations (including the holding of title to the Trust or any portion thereof in any such jurisdiction) shall be exercised and performed by such separate trustee or co-trustee at the direction of the Trustee.

(c)            Any notice, request or other writing given to the Trustee shall be deemed to have been given to each of the then-separate trustees and co-trustees, as effectively as if given to each of them. Every instrument appointing any separate trustee or co-trustee shall refer to this Agreement and the conditions of this Article VIII. Each separate trustee and co-trustee, upon its acceptance of the trusts conferred, shall be vested with the estates or property specified in its instrument of appointment, either jointly with the Trustee or separately, as may be provided therein, subject to all the provisions of this Agreement, specifically including every provision of this Agreement relating to the conduct of, affecting the liability of, or affording protection to, the Trustee. Every such instrument shall be filed with the Trustee.

(d)            Any separate trustee or co-trustee may, at any time, constitute the Trustee, its agent or attorney-in-fact, with full power and authority, to the extent not prohibited by law, to

 -489-

do any lawful act under or in respect of this Agreement on its behalf and in its name. If any separate trustee or co-trustee shall die, become incapable of acting, resign or be removed, all of its estates, properties, rights, remedies and trusts shall vest in and be exercised by the Trustee, to the extent permitted by law, without the appointment of a new or successor trustee.

(e)            The appointment of a co-trustee or separate trustee under this Section 8.10 shall not relieve the Trustee of its duties and responsibilities hereunder.

The Custodian shall be subject to the same obligations and standard of care as would be imposed on the Certificate Administrator hereunder in connection with the retention of Mortgage Files directly by the Certificate Administrator. Upon termination or resignation of the Custodian, the Certificate Administrator may appoint another Custodian meeting the foregoing requirements. The appointment of one or more Custodians by the Certificate Administrator shall not relieve the Certificate Administrator from any of its obligations hereunder, and the Certificate Administrator shall remain responsible for all acts and omissions of any Custodian. Any Custodian appointed hereunder must maintain a fidelity bond and errors and omissions policy in an amount customary for Custodians which serve in such capacity in commercial mortgage loan securitization transactions, or may self-insure.

Section 8.12     Representations and Warranties of the Trustee.

that in no event shall the trust created hereby continue beyond the expiration of twenty-one (21) years from the death of the last survivor of the descendants of Joseph P. Kennedy, the late ambassador of the United States to the Court of St. James’s, living on the date hereof.

Following the date on which the Certificate Balances and Notional Amounts, as applicable, of the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class X-A, Class X-B, Class A-S, Class B and Class C Regular Interests have been reduced to zero (and provided that there is only one Holder (or multiple Holders acting in unanimity) of the then-outstanding Certificates (other than the Class Z and Class R Certificates and the VRR Interest)), the Sole Certificateholder shall have the right, with the consent of the Master Servicer, to exchange all of its Certificates (other than the Class Z and Class R Certificates and the VRR Interest) together with the payment or deemed payment of the Termination Purchase Amount for all of the Mortgage Loans, Trust Subordinate Companion Loans and each REO Property remaining in the Trust Fund as contemplated by clause (iii) of the first paragraph of this Section 9.01 by giving written notice to all the parties hereto no later than sixty (60) days prior to the anticipated date of exchange. In the event that the Sole Certificateholder elects to exchange all of its Certificates (other than the Loan-Specific Certificates and Class Z and Class R Certificates) and pay the Termination Purchase Amount) for all of the Mortgage Loans, the Trust Subordinate Companion Loans and the Trust’s portion of each REO Property remaining in the Trust in accordance with the preceding sentence, such Sole Certificateholder, not later than the Distribution Date on which the final distribution on the Certificates is to occur, shall (i) remit for deposit in the Collection Account an amount in immediately available funds equal to (a) an amount equal to the product of (y) the VRR Retention Percentage and (z) the Termination Purchase Amount to be paid to the Holders of the VRR Interest in exchange for the surrender of the VRR Interest, (b) an amount equal to the product of (x) 1.00 minus the VRR Retention Percentage and (y) the Termination Purchase Amount to be paid to the Trust, plus (z) all amounts due and owing to the Depositor, the Master Servicer, the Special Servicer, the Trustee and the Certificate Administrator hereunder through the date of the liquidation of the Trust that may be withdrawn from the Collection Account, or an escrow account acceptable to the respective parties hereto, pursuant to Section 3.05(a) or that may be withdrawn from the Distribution Account pursuant to Section 3.05(a), but only to the extent that such amounts are not already on deposit in the Collection Account, and (ii) be deemed to pay to the Trust (which amount shall be further deemed distributed to the Holders of all outstanding Certificates) an amount equal to the Termination Purchase Amount. In addition, the Master Servicer shall transfer all amounts required to be transferred to the Lower-Tier REMIC Distribution Account and Excess Interest Distribution Account on the P&I Advance Date related to such Distribution Date in which the final distribution on the Certificates is to occur from the Collection Account pursuant to the first paragraph of Section 3.04(b) (provided, however, that if a Serviced Whole Loan is secured by REO Property, the portion of the above-described purchase price allocable to such Trust’s portion of REO Property shall initially be deposited into the related REO Account). Upon confirmation that such final deposits have been made and following the surrender of all its Certificates (other than the Class Z Certificates and Class R Certificates) on the applicable Distribution Date, the Custodian shall, upon receipt of a Request for Release from the Master Servicer, release or cause to be released to the Sole Certificateholder or any designee thereof, the Mortgage Files for the remaining Mortgage Loans and the Trust Subordinate Companion Loans and shall execute all assignments, endorsements and other instruments furnished to it by the Sole Certificateholder as shall be necessary to effectuate transfer of the Mortgage Loans, the Trust

 -495-

Subordinate Companion Loans and REO Properties remaining in the Trust Fund, and the Trust shall be liquidated in accordance with Section 9.02. Solely for federal income tax purposes, the Sole Certificateholder shall be deemed to have purchased the assets of the Lower-Tier REMIC for an amount equal to the remaining Certificate Balance of the Principal Balance Certificates, plus accrued, unpaid interest with respect thereto, and the Certificate Administrator shall credit such amounts against amounts distributable in respect of such Certificates and Related Lower-Tier Regular Interests.

The obligations and responsibilities under this Agreement of the Depositor, the Master Servicer, the Special Servicer, the Trustee, the Certificate Administrator and the Companion Paying Agent shall terminate with respect to any Companion Loan to the extent (i) its related Serviced Mortgage Loan has been paid in full or is no longer part of the Trust Fund and (ii) no amounts payable by the related Companion Holder to or for the benefit of the Trust or any party hereto in accordance with the related Intercreditor Agreement remain due and owing.

The Holders of the majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates, in that order of priority, may, at their option, elect to purchase all of the Mortgage Loans (and all property acquired through exercise of remedies in respect of any related Mortgage Loan), the Trust Subordinate Companion Loans and the Trust’s portion of each REO Property remaining in the Trust Fund as contemplated by clause (ii) of the first paragraph of this Section 9.01 by giving written notice to the Trustee, the Certificate Administrator, and the other parties hereto no later than sixty (60) days prior to the anticipated date of purchase; provided, however, that the Holders of the Controlling Class, the Special Servicer, the Master Servicer, or the Holders of the Class R Certificates may so elect to purchase all of the Mortgage Loans, the Trust Subordinate Companion Loans and the Trust’s portion of each REO Property remaining in the Trust Fund only on or after the first Distribution Date on which the aggregate Stated Principal Balance of the Mortgage Loans, the Trust Subordinate Companion Loans and any REO Mortgage Loans held by the Trust is equal to or greater than 1.0% of the aggregate Cut-off Date Balance of the Mortgage Loans and the Trust Subordinate Companion Loans (solely for the purposes of this calculation, if such right is being exercised after December 2027 and the 237 East Fordham Road Mortgage Loan is still an asset of the Trust, then such Mortgage Loan will be excluded from the then-aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate Companion Loans and from the aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate Companion Loans as of the Cut-off Date) as set forth in the Preliminary Statement.

In the event that the Master Servicer or the Special Servicer purchases, or the Holders of the majority of the Controlling Class or the Holders of the Class R Certificates purchase, all of the Mortgage Loans, the Trust Subordinate Companion Loans and the Trust’s portion of each REO Property remaining in the Trust Fund in accordance with the preceding sentence, the Master Servicer, the Special Servicer, the Holders of the majority of the Controlling Class or the Holders of the Class R Certificates, as applicable, shall deposit in the Lower-Tier REMIC Distribution Account not later than the P&I Advance Date relating to the Distribution Date on which the final distribution on the Certificates is to occur, an amount in immediately available funds equal to the above-described purchase price (exclusive of any portion thereof payable to any Person other than the Certificateholders pursuant to Section 3.05(a), which portion shall be deposited in the Collection Account). In addition, the

 -496-

Master Servicer shall transfer to the Lower-Tier REMIC Distribution Account all amounts required to be transferred thereto on such P&I Advance Date from the Collection Account pursuant to the first paragraph of Section 3.04(b), together with any other amounts on deposit in the Collection Account that would otherwise be held for future distribution. Upon confirmation that such final deposits and payments have been made, the Custodian shall release or cause to be released to the Master Servicer, the Special Servicer, the Holders of the majority of the Controlling Class or the Holders of the Class R Certificates, as applicable, the Mortgage Files for the remaining Mortgage Loans and Trust Subordinate Companion Loans and shall execute all assignments, endorsements and other instruments furnished to it by the Master Servicer, the Special Servicer, the Holders of the majority of the Controlling Class or the Holders of the Class R Certificates, as applicable, as shall be necessary to effectuate transfer of the Mortgage Loans, Trust Subordinate Companion Loans and REO Properties remaining in the Trust Fund.

For purposes of this Section 9.01, the Holders of the majority of the Controlling Class shall have the first option to terminate the Trust REMICs, then the Special Servicer, then the Master Servicer, and then the Holders of the Class R Certificates. For purposes of this Section 9.01, the Directing Certificateholder with the consent of the Holders of the Controlling Class, shall act on behalf of the Holders of the Controlling Class in purchasing the assets of the Trust and terminating the Trust.

Notice of any termination pursuant to this Section 9.01 shall be given promptly by the Certificate Administrator by letter to the Certificateholders, each Serviced Companion Noteholder and the 17g-5 Information Provider in accordance with the provisions of Section 3.13(c) (who shall promptly post a copy of such additional notice on the 17g-5 Information Provider’s Website in accordance with the provisions of Section 3.13(c)) and, if not previously notified pursuant to this Section 9.01, to the other parties hereto mailed (a) in the event such notice is given in connection with the purchase of all of the Mortgage Loans, the Trust Subordinate Companion Loans and each REO Property remaining in the Trust Fund, not earlier than the 15th day and not later than the 25th day of the month next preceding the month of the final distribution on the Certificates, or (b) otherwise during the month of such final distribution on or before the P&I Advance Determination Date in such month, in each case specifying (i) the Distribution Date upon which the Trust will terminate and final payment of the Certificates will be made, (ii) the amount of any such final payment and (iii) that the Record Date otherwise applicable to such Distribution Date is not applicable, payments being made only upon presentation and surrender of the Certificates at the offices of the Certificate Registrar or such other location therein designated.

After transferring the Lower-Tier Distribution Amount and the Trust Subordinate Companion Loan REMIC Distribution Amounts, as applicable, and the amount of any Yield Maintenance Charges distributable to the Regular Certificates pursuant to Section 4.01(i) to the Upper-Tier REMIC Distribution Account, in each case pursuant to Section 3.04(b) and upon presentation and surrender of the Certificates by the Certificateholders on the final Distribution Date, the Certificate Administrator shall distribute to each Certificateholder so presenting and surrendering its Certificates (i) such Certificateholder’s Percentage Interest of that portion of the amounts then on deposit in the Upper-Tier REMIC Distribution Account that are allocable to payments on the Class of Regular Certificates so presented, (ii) to Holders of the Class V1-Z, Class V2-Z and Class Z Certificates so presented, any amounts remaining on deposit in the

 -497-

Excess Interest Distribution Account, and (iii) any remaining amount shall be distributed to the Class R Certificates in respect of the Class UES-R Interest, Class STN-R Interest, Class LR Interest or the Class UR Interest, as applicable. Amounts transferred from the Y&L Towers Companion Loan REMIC Distribution Account, the Standard Highline Companion Loan REMIC Distribution Account and the Lower-Tier REMIC Distribution Account to the Upper-Tier REMIC Distribution Account, as of the final Distribution Date, shall be distributed in termination and liquidation of the Y&L Towers Companion Loan REMIC Regular Interests and the Class UES-R Interest, the Standard Highline Companion Loan REMIC Regular Interests and the Class STN-R Interest or the Lower-Tier Regular Interests and the Class LR Interest in accordance with Section 4.01(a), Section 4.01(b), Section 4.01(c), Section 4.01(i), 4.01(g), and Section 4.01(i)(xvi). Any funds not distributed on such Distribution Date shall be set aside and held uninvested in trust for the benefit of the Certificateholders not presenting and surrendering their Certificates in the aforesaid manner and shall be disposed of in accordance with this Section 9.01 and Section 4.01(l).

Section 9.02    Additional Termination Requirements. (a) In the event the Master Servicer or the Special Servicer purchases, or the Holders of the Controlling Class or the Holders of the Class R Certificates purchase, all of the Mortgage Loans, the Trust Subordinate Companion Loans and the Trust’s portion of each REO Property remaining in the Trust Fund as provided in Section 9.01, or in the event Holders of the Y&L Towers Loan-Specific Certificates or the Standard Highline Loan-Specific Certificates exchange their Certificates for the related Trust Subordinate Companion Loan, the Upper-Tier REMIC, Lower-Tier REMIC, Y&L Towers Companion Loan REMIC or Standard Highline Companion Loan REMIC, as the case may be, shall be terminated in accordance with the following additional requirements, which meet the definition of a “qualified liquidation” in Section 860F(a)(4) of the Code:

(ii)          during the 90-day liquidation period and at or prior to the time of the making of the final payment on the Certificates, the Certificate Administrator on behalf of the Trustee shall sell all of the assets of the related Trust REMICs to the Master Servicer, the Special Servicer, the Holders of the Controlling Class or the Holders of the Class R Certificates, as applicable, for cash; and

(iii)         within such 90-day liquidation period and immediately following the making of the final payment on the Lower-Tier Regular Interests and the Certificates, the Certificate Administrator shall distribute or credit, or cause to be distributed or credited, to the Holders of the Class R Certificates in respect of the Class LR Interest (in the case of the Lower-Tier REMIC), in respect of the Class UR Interest (in the case of the Upper-Tier REMIC) and in respect of the Class UES-R Interest (in the case of the Y&L Towers Companion Loan REMIC) and in respect of the Class STN-R Interest (in the case of the Standard Highline Companion Loan REMIC) all cash on hand (other than cash retained to meet claims), and the Trust (if applicable) or the related Trust REMIC(s) shall terminate at that time.

(b)            The Closing Date is hereby designated as the “startup day” (the “Startup Day”) of each Trust REMIC within the meaning of Section 860G(a)(9) of the Code.

(c)            The Certificate Administrator shall act on behalf of each Trust REMIC in relation to any tax matter or controversy involving either such REMIC and shall represent each such REMIC in any administrative or judicial proceeding relating to an examination or audit by any governmental taxing authority with respect thereto. The legal expenses, including without limitation attorneys’ or accountants’ fees, and costs of any such proceeding and any liability resulting therefrom shall be expenses of the Trust and the Certificate Administrator shall be entitled to reimbursement therefor out of amounts attributable to the Mortgage Loans, the Trust Subordinate Companion Loans and any REO Properties on deposit in the Collection Account as provided by Section 3.05(a) unless such legal expenses and costs are incurred by reason of the Certificate Administrator’s willful misconduct, bad faith or negligence. By their acceptance thereof, the Holders of the largest Percentage Interest of the Class R Certificates shall be designated as the “tax matters person”, in the manner provided under Treasury Regulations Section 1.860F-4(d) and Treasury Regulations Section 301.6231(a)(7)-1, and the “partnership representative”, within the meaning of Section 6223 of the Code (to the extent such provision is

(e)            The Certificate Administrator shall provide or cause to be provided (i) to any Transferor of a Class R Certificate such information as is necessary for the application of any tax relating to the transfer of such Class R Certificate to any Person who is a Disqualified Organization, or in the case of a Transfer to an agent thereof, to such agent, (ii) to the Certificateholders such information or reports as are required by the Code or the REMIC Provisions including reports relating to interest, original issue discount and market discount or premium (using the Prepayment Assumption) and (iii) to the Internal Revenue Service, in respect of each Trust REMIC, Form 8811, within thirty (30) days after the Closing Date.

Neither the Master Servicer nor the Special Servicer shall knowingly or intentionally take any action, cause the Trust to take any action or fail to take (or fail to cause to be taken) any action reasonably within its control and the scope of duties more specifically set forth herein, that, under the REMIC Provisions, if taken or not taken, as the case may be, could (i) cause any Trust REMIC to fail to qualify as a REMIC or (ii) result in the imposition of a tax upon any Trust REMIC or the Trust (including but not limited to the tax on “prohibited transactions” as defined in Section 860F(a)(2) of the Code and the tax on contributions to a REMIC set forth in Section 860G(d) of the Code, but not including the tax on “net income from foreclosure property”) (either such event, an “Adverse REMIC Event”) unless the Certificate Administrator receives an Opinion of Counsel (at the expense of the party seeking to take such action or, if such party fails to pay such expense, and the Certificate Administrator determines that taking such action is in the best interest of the Trust and the Certificateholders, at the expense of the Trust, but in no event at the expense of the Certificate Administrator or the Trustee) to the effect that the contemplated action will not, with respect to the Trust, any Trust REMIC created hereunder, endanger such status or, unless the Certificate Administrator determines in its sole discretion to indemnify the Trust against such tax, result in the imposition of such a tax (not including a tax on “net income from foreclosure property”). The Trustee shall not take or fail to take any action (whether or not authorized hereunder) as to which the Certificate Administrator has advised it in writing that it has received an Opinion of Counsel to the effect that an Adverse REMIC Event could occur with respect to such action. The Certificate Administrator may consult with counsel to make such written advice, and the cost of same shall be borne by the

 -500-

party seeking to take the action not expressly permitted by this Agreement, but in no event at the expense of the Certificate Administrator or the Trustee.

(g)            In the event that any applicable federal, state or local tax, including interest, penalties or assessments, additional amounts or additions to tax, is imposed on any Trust REMIC, such tax shall be charged against amounts otherwise distributable to the Holders of the Certificates, except as provided in the last sentence of this Section 10.01(g); provided that with respect to the estimated amount of tax imposed on any “net income from foreclosure property” pursuant to Section 860G(c) of the Code or any similar tax imposed by a state or local tax authority, the Special Servicer shall retain in the related REO Account a reserve for the payment of such taxes in such amounts and at such times as it shall deem appropriate (or as advised by the Certificate Administrator in writing), and shall remit to the Master Servicer such reserved amounts as the Master Servicer shall request in order to pay such taxes. Except as provided in the preceding sentence, the Master Servicer shall withdraw from the Collection Account sufficient funds to pay or provide for the payment of, and to actually pay, such tax as is estimated to be legally owed by any Trust REMIC (but such authorization shall not prevent the Certificate Administrator from contesting, at the expense of the Trust (other than as a consequence of a breach of its obligations under this Agreement), any such tax in appropriate proceedings, and withholding payment of such tax, if permitted by law, pending the outcome of such proceedings). The Certificate Administrator is hereby authorized to and shall segregate, into a separate non-interest bearing account, the net income from any “prohibited transaction” under Section 860F(a) of the Code or the amount of any taxable contribution to any Trust REMIC after the Startup Day that is subject to tax under Section 860G(d) of the Code and use such income or amount, to the extent necessary, to pay such prohibited transactions tax. To the extent that any such tax (other than any such tax paid in respect of “net income from foreclosure property”) is paid to the Internal Revenue Service or applicable state or local tax authorities, the Certificate Administrator shall retain an equal amount from future amounts otherwise distributable to the Holders of Class R Certificates (as applicable) and shall distribute such retained amounts, (w) in the case of the Y&L Towers Trust Subordinate Companion Loan REMIC Regular Interests, to the Upper-Tier REMIC to the extent they are fully reimbursed for any Y&L Towers Realized Losses arising therefrom and then to the Holders of the Class R Certificates in respect of the Class UES-R Interest respectively in the manner specified in Section 4.01(c), (x) in the case of the Standard Highline Trust Subordinate Companion Loan REMIC Regular Interests, to the Upper-Tier REMIC to the extent they are fully reimbursed for any Standard Highline Realized Losses arising therefrom and then to the Holders of the Class R Certificates in respect of the Class STN-R Interest respectively in the manner specified in Section 4.01(c), (y) in the case of the Lower-Tier Regular Interests, to the Upper Tier REMIC to the extent they are fully reimbursed for any Realized Losses arising therefrom and then to the Holders of the Class R Certificates in respect of the Class LR Interest in the manner specified in Section 4.01(c) and (z) in the case of the Upper-Tier REMIC, to the Holders of the Principal Balance Certificates in the manner specified in Section 4.01(a) or Section 4.01(b), as applicable, to the extent they are fully reimbursed for any Realized Losses arising therefrom and then to the Holders of the Class R Certificates in respect of the Class UR Interest. None of the Trustee, the Certificate

 -501-

Administrator, the Master Servicer or the Special Servicer shall be responsible for any taxes imposed on any Trust REMIC except to the extent such taxes arise as a consequence of a breach of their respective obligations under this Agreement which breach constitutes willful misconduct, bad faith, or negligence by such party.

(h)            The Certificate Administrator shall, for federal income tax purposes, maintain or cause to be maintained books and records with respect to each Trust REMIC on a calendar year and on an accrual basis or as otherwise may be required by the REMIC Provisions.

(i)             Following the Startup Day, neither the Certificate Administrator nor the Trustee shall accept any contributions of assets to any Trust REMIC unless the Certificate Administrator and the Trustee shall have received an Opinion of Counsel (at the expense of the party seeking to make such contribution) to the effect that the inclusion of such assets in such Trust REMIC will not cause an Adverse REMIC Event to occur.

(j)             Neither the Certificate Administrator nor the Trustee shall enter into any arrangement by which the Trust or any Trust REMIC will receive a fee or other compensation for services nor permit the Trust or any Trust REMIC to receive any income from assets other than “qualified mortgages” as defined in Section 860G(a)(3) of the Code or “permitted investments” as defined in Section 860G(a)(5) of the Code.

(k)            Solely for the purposes of Treasury Regulations Section 1.860G-1(a)(4)(iii), the “latest possible maturity date” by which (i) the Certificate Balance or Notional Amount of each Class of Regular Interests representing a “regular interest” in the Upper-Tier REMIC would be reduced to zero and (ii) the Lower-Tier Principal Amount of each Class of Lower-Tier Regular Interests representing a “regular interest” in the Lower-Tier REMIC and the Trust Subordinate Companion Loan REMIC Regular Interests would be reduced to zero is the date that is the Rated Final Distribution Date.

(l)             None of the Trustee, the Certificate Administrator, the Master Servicer or the Special Servicer, as applicable, shall sell, dispose of or substitute for any of the Mortgage Loans or Trust Subordinate Companion Loans (except in connection with (i) the default, imminent default or foreclosure of a Mortgage Loan or Trust Subordinate Companion Loan, including but not limited to, the acquisition or sale of a Mortgaged Property acquired by foreclosure or deed in lieu of foreclosure, (ii) the bankruptcy of the Trust, (iii) the termination of the Trust pursuant to Article IX of this Agreement or (iv) a purchase of Mortgage Loans or Trust Subordinate Companion Loans pursuant to Article II or Article III of this Agreement) or acquire any assets for the Trust or any Trust REMIC or sell or dispose of any investments in the Collection Account or the REO Account for gain unless it has received an Opinion of Counsel that such sale, disposition or substitution will not (a) affect adversely the status of any Trust REMIC as a REMIC or (b) unless the Trustee, the Certificate Administrator, the Master Servicer or the Special Servicer, as applicable, has determined in its sole discretion to indemnify the Trust against such tax, cause the Trust or any Trust REMIC to be subject to a tax on “prohibited transactions” pursuant to the REMIC Provisions.

(m)           The Certificate Administrator’s authority under this Agreement includes the authority to make, and the Certificate Administrator is hereby directed to make, any elections

Section 11.16     Certain Matters Relating to the Future Securitization of the Serviced Pari Passu Companion Loans.  (a) Each of the Trustee, the Certificate Administrator, the Master Servicer and the Special Servicer shall, and the Master Servicer and the Special Servicer shall use commercially reasonable efforts to cause any sub-servicer appointed with respect to any Serviced Pari Passu Companion Loan to, upon written request or notice from a Mortgage Loan Seller (or a permitted transferee of such Mortgage Loan Seller pursuant to the related Intercreditor Agreement), reasonably cooperate with the Mortgage Loan Seller (or such permitted transferee) selling any Serviced Pari Passu Companion Loan into a securitization that is required to comply with Regulation AB (a “Regulation AB Companion Loan Securitization”) and, to the extent needed in order to comply with Regulation AB, provide to the Mortgage Loan Seller (or such permitted transferee) information about itself that such Mortgage Loan Seller reasonably requires to meet the requirements of Items 1117 and 1119 and paragraphs (b), (c)(3), (c)(4) and (c)(5) of Item 1108 of Regulation AB and shall reasonably cooperate with such Mortgage Loan Seller to provide such other information as may be reasonably necessary to comply with the requirements of Regulation AB. Each of the Trustee, the Certificate Administrator, the Master Servicer and the Special Servicer understands that such information may be included in the offering material related to a Regulation AB Companion Loan Securitization and agrees to negotiate in good faith an agreement (subject to the final sentence of this sub-section) to indemnify and hold the related depositor and underwriters involved in the offering of the related Certificates harmless for any costs, liabilities, fees and expenses incurred by the depositor or such underwriters as a result of any material misstatements or omissions or alleged material misstatements or omissions in any such offering material to the extent that such material misstatement or omission was made in reliance upon any such information provided by the Trustee (where such information pertains to the Trustee individually and not to any specific

Section 12.01     Asset Review.

(a)          On or prior to each Distribution Date, based on either the CREFC^® Delinquent Mortgage Loan Status Report or the CREFC^® Loan Periodic Update File, the Certificate Administrator shall determine if an Asset Review Trigger has occurred. If an Asset Review Trigger is determined to have occurred, the Certificate Administrator shall promptly provide written notice to the Asset Representations Reviewer and to all Pooled Certificateholders and each other party to this Agreement. Any notice required to be delivered to the Pooled Certificateholders pursuant to this Section 12.01 shall be delivered by the Certificate Administrator by posting such notice on the Certificate Administrator’s Website, by mailing to their addresses appearing in the Certificate Register and by delivering such notice via the Depository. The Certificate Administrator shall include in the Form 10-D relating to the

 -532-

distribution period in which the Asset Review Trigger occurred a description of the events that caused the Asset Review Trigger to occur. On each Distribution Date after providing such notice to the Pooled Certificateholders, the Certificate Administrator, based on information provided to it by the Master Servicer, shall determine whether (1) any additional Mortgage Loan has become a Delinquent Loan, (2) any Mortgage Loan has ceased to be a Delinquent Loan and (3) an Asset Review Trigger has ceased to exist, and, if there is an occurrence of any of the events or circumstances identified in clauses (1), (2) and/or (3), deliver written notice of such information (which may be via email) in the form of Exhibit SS within two (2) Business Days to the Master Servicer, the Special Servicer, the Operating Advisor and the Asset Representations Reviewer.

If the Pooled Certificateholders evidencing not less than 5% of the Pooled Voting Rights of the Certificates deliver to the Certificate Administrator, within 90 days after the filing of the Form 10-D reporting the occurrence of an Asset Review Trigger, a written direction requesting a vote to commence an Asset Review (such written direction, the “Asset Review Vote Election”), then the Certificate Administrator shall promptly provide written notice thereof to the Asset Representations Reviewer and to all Pooled Certificateholders and conduct a solicitation of votes to authorize an Asset Review. Upon the affirmative vote to authorize an Asset Review of Holders of Certificates evidencing at least a majority of an Asset Review Quorum within 150 days of receipt of the Asset Review Vote Election (an “Affirmative Asset Review Vote”), the Certificate Administrator shall promptly provide written notice thereof to all parties to this Agreement, the Underwriters, the Mortgage Loan Sellers, the Directing Holder, the Risk Retention Consultation Party and the other Pooled Certificateholders (the “Asset Review Notice”). Upon receipt of an Asset Review Notice, the Asset Representations Reviewer shall request access to the Secure Data Room by providing to the Certificate Administrator a certification in the form attached hereto as Exhibit RR. Upon receipt of such certification, the Certificate Administrator shall promptly (and in any case within two (2) Business Days after such receipt) grant the Asset Representations Reviewer access to the Secure Data Room. In the event an Affirmative Asset Review Vote has not occurred within such 150-day period following the receipt of the Asset Review Vote Election, no Pooled Certificateholder may request a vote or cast a vote for an Asset Review and the Asset Representations Reviewer shall not be required to review any Delinquent Loan unless and until (A) an additional Mortgage Loan has become a Delinquent Loan after the expiration of such 150-day period, (B) an additional Asset Review Trigger has occurred as a result or otherwise is in effect, (C) the Certificate Administrator has timely received an Asset Review Vote Election after the occurrence of the events described in clauses (A) and (B) in this sentence and (D) an Affirmative Asset Review Vote has occurred within 150 days after the Asset Review Vote Election described in clause (C) in this sentence. After the occurrence of any Asset Review Vote Election or an Affirmative Asset Review Vote, no Pooled Certificateholder may make any additional Asset Review Vote Election except as described in the immediately preceding sentence. Any reasonable out-of-pocket expenses incurred by the Certificate Administrator in connection with administering such vote will be paid as an expense of the Trust from the Collection Account. The Certificate Administrator shall be entitled to administer any vote in connection with the foregoing through an agent.

(b)          (i) If an Affirmative Asset Review Vote has occurred, the Certificate Administrator shall promptly provide written notice thereof to all parties to this Agreement, the Underwriters, Sponsors, the Directing Holder, the Risk Retention Consultation Party and all other Pooled Certificateholders. Upon receipt of an Asset Review Notice, the Custodian (with

documents and agreements, and request the Master Servicer or the Special Servicer, as applicable, promptly, but in no event later than ten (10) Business Days after receipt of such notification from the Asset Representations Reviewer, to deliver to the Asset Representations Reviewer such missing documents and agreements to the extent in its possession. In the event any missing documents or agreements are not provided by the Master Servicer or the Special Servicer, as applicable, within such ten (10) Business Day period, the Asset Representations Reviewer shall contact the related Mortgage Loan Seller to request such documents or agreements from the Mortgage Loan Seller. The Mortgage Loan Seller will be required to deliver such additional documents and agreements only to the extent in the possession of such Mortgage Loan Seller.

(iii)         The Asset Representations Reviewer may, but is under no obligation to, consider and rely upon information furnished to it by a Person that is not a party to this Agreement or the related Mortgage Loan Seller, and shall do so only if such information can be independently verified (without unreasonable effort or expense to the Asset Representations Reviewer) and is determined by the Asset Representations Reviewer in its good faith and sole discretion to be relevant to the Asset Review (any such information, “Unsolicited Information”) conducted pursuant to this Section 12.01 hereof.

(iv)         Upon receipt by the Asset Representations Reviewer of the Asset Review Notice and access to the Review Materials with respect to a Delinquent Loan, the Asset Representations Reviewer, as an independent contractor, shall commence an Asset Review. The Asset Representations Reviewer shall perform an Asset Review with respect to each representation and warranty made by the related Mortgage Loan Seller with respect to such Delinquent Loan in accordance with the Asset Review Standard and the procedures set forth on Exhibit QQ (each such procedure, a “Test”). Once an Asset Review of a Mortgage Loan is completed, no further Asset Review shall be required in respect of, or performed on, such Mortgage Loan notwithstanding that such Mortgage Loan may continue to be a Delinquent Loan or again become a Delinquent Loan at a time when a new Asset Review Trigger occurs and a new Affirmative Asset Review Vote is obtained subsequent to the occurrence of such new Asset Review Trigger.

(v)          No Certificateholder shall have the right to change the scope of the Asset Review, and the Asset Representations Reviewer shall not be required to review any information other than (x) the Review Materials and (y) if applicable, Unsolicited Information.

(vi)         The Asset Representations Reviewer may, absent manifest error and subject to the Asset Review Standard, (i) assume, without independent investigation or verification, that the Review Materials are accurate and complete in all material respects and (ii) conclusively rely on such Review Materials.

(vii)        In the event that the Asset Representations Reviewer determines that the Review Materials are insufficient to complete a Test and such missing information and documentation is not delivered to the Asset Representations Reviewer by the Master Servicer (with respect to non-Specially Serviced Loans) or the Special Servicer (with respect to Specially Serviced Loans) to the extent in the Master Servicer’s or the Special

 -535-

Servicer’s possession within 10 Business Days or by the related Mortgage Loan Seller upon request by the Asset Representations Reviewer shall list such missing information and documents in a preliminary report setting forth the preliminary results of the application of the Tests and the reasons why such missing information and documents are necessary to complete a Test and (if the Asset Representations Reviewer has so concluded) that the absence of such information and documents will be deemed to be a failure of such Test. The Asset Representations Reviewer shall provide such preliminary report to the Master Servicer (with respect to non-Specially Serviced Loans) or the Special Servicer (with respect to Specially Serviced Loans) and the related Mortgage Loan Seller. If the preliminary report indicates that any of the representations and warranties fails or is deemed to fail any Test, the related Mortgage Loan Seller shall have ninety (90) days (the “Cure/Contest Period”) to remedy or otherwise refute the failure. Any information and documents provided or explanations given to support the Mortgage Loan Seller’s claim that the representation and warranty has not failed a Test or that any missing information or documents in the Review Materials are not required to complete a Test shall be promptly delivered by the related Mortgage Loan Seller to the Asset Representations Reviewer. For the avoidance of doubt, the Asset Representations Reviewer shall not be required to prepare a preliminary report in the event the Asset Representations Reviewer determines that there is no Test failure with respect to the related Mortgage Loan.

(viii)       The Asset Representations Reviewer shall, within the later of (x) 60 days after the date on which access to the Diligence Files in the Secure Data Room is made available to the Asset Representations Reviewer by the Certificate Administrator or (y) 10 days after the expiration of the Cure/Contest Period, complete an Asset Review with respect to each Delinquent Loan and deliver (i) a report setting forth the Asset Representations Reviewer’s findings and conclusions as to whether or not it has determined there is any evidence of a failure of any Test based on the Asset Review and a statement that the Asset Representations Reviewer’s findings and conclusions set forth in such report were not influenced by any third party (an “Asset Review Report”) to each party to this Agreement and the related Mortgage Loan Seller for each Delinquent Loan, and (ii) a summary of the Asset Representations Reviewer’s conclusions included in such Asset Review Report (an “Asset Review Report Summary”) to the Trustee and Certificate Administrator. The period of time by which the Asset Review Report must be completed and delivered may be extended by up to an additional thirty (30) days, upon written notice to the parties to this Agreement and the related Mortgage Loan Seller, if the Asset Representations Reviewer determines pursuant to the Asset Review Standard that such additional time is required due to the characteristics of the Mortgage Loans and/or the Mortgaged Property or Mortgaged Properties. In no event may the Asset Representations Reviewer determine whether any Test failure constitutes a Material Defect, or whether the Trust should enforce any rights it may have against the related Mortgage Loan Seller, which, in each such case, will be the responsibility of the Enforcing Servicer.

(ix)          In addition, in the event that the Asset Representations Reviewer does not receive any information or documentation that it requested from the Master Servicer (with respect to non-Specially Serviced Loans) or the Special Servicer (with respect to Specially Serviced Loans) or the related Mortgage Loan Seller in sufficient time to allow the Asset Representations Reviewer to complete its Asset Review and deliver an Asset Review

 -536-

Report, the Asset Representations Reviewer shall prepare the Asset Review Report solely based on the information received by the Asset Representations Reviewer with respect to the related Delinquent Loan, and the Asset Representations Reviewer shall have no responsibility to independently obtain any such information from any party to this Agreement.

(x)          Within forty-five (45) days after receipt of an Asset Review Report with respect to any Mortgage Loan, the Special Servicer shall determine whether at that time, based on the Servicing Standard, there exists a Material Defect with respect to such Mortgage Loan. If the Special Servicer determines that a Material Defect exists, the Special Servicer shall enforce the obligations of the related Mortgage Loan Seller with respect to such Material Defect in accordance with Section 2.03(b).

(xi)          For the avoidance of doubt, the Asset Representations Reviewer shall not perform an Asset Review with respect to any Trust Subordinate Companion Loan at any time.

(c)          The Asset Representations Reviewer and its Affiliates shall keep all information appropriately labeled as “Privileged Information” confidential and shall not disclose such Privileged Information to any Person (including Certificateholders), other than (1) to the extent expressly required by this Agreement in an Asset Review Report or otherwise, to the other parties to this Agreement with a notice indicating that such information is Privileged Information or (2) pursuant to a Privileged Information Exception. Each party to this Agreement that receives Privileged Information from the Asset Representations Reviewer with a notice stating that such information is Privileged Information shall not disclose such Privileged Information to any Person without the prior written consent of the Special Servicer other than pursuant to a Privileged Information Exception.

(d)          The Asset Representations Reviewer may delegate its duties to agents or subcontractors so long as the related agreements or arrangements with such agents or subcontractors are consistent with the provisions of this Section 12.01; provided that no agent or subcontractor may (1) be affiliated with a Sponsor, Master Servicer, the Special Servicer, the Depositor, the Certificate Administrator, the Trustee, the Directing Certificateholder or any of their respective Affiliates or (ii) have been paid any fees, compensation or other remuneration by an Underwriter, Master Servicer, the Special Servicer, the Depositor, the Certificate Administrator, the Trustee, the Directing Certificateholder or any of their respective Affiliates in connection with due diligence or other services with respect to any Mortgage Loan prior to the Closing Date. Notwithstanding the foregoing sentence, the Asset Representations Reviewer shall remain obligated and primarily liable for any Asset Review required hereunder in accordance with the provisions of this Agreement without diminution of such obligation or liability or related obligation or liability by virtue of such delegation or arrangements or by virtue of indemnification from any Person acting as its agents or subcontractor to the same extent and under the same terms and conditions as if the Asset Representations Reviewer alone were performing its obligations under this Agreement. The Asset Representations Reviewer shall be entitled to enter into an agreement with any agent or subcontractor providing for indemnification of the Asset Representations Reviewer by such agent or subcontractor, and nothing contained in this Agreement shall be deemed to limit or modify such indemnification.

 -537-

(e)          The Asset Representations Reviewer may assign its rights and obligations under this Agreement in connection with the sale or transfer of all or substantially all of its Asset Representations Reviewer portfolio, provided that: (i) the purchaser or transferee accepting such assignment and delegation (A) is an Eligible Asset Representations Reviewer, organized and doing business under the laws of the United States of America, any state of the United States of America or the District of Columbia, authorized under such laws to perform the duties of the asset representations reviewer resulting from a merger, consolidation or succession that is permitted under this Agreement, (B) executes and delivers to the Trustee and the Certificate Administrator an agreement that contains an assumption by such person of the due and punctual performance and observance of each covenant and condition to be performed or observed by the asset representations reviewer under this Agreement from and after the date of such agreement and (C) is not a Prohibited Party under this Agreement; (ii) the Asset Representations Reviewer shall not be released from its obligations under this Agreement that arose prior to the effective date of such assignment and delegation; (iii) the rate at which the Asset Representations Reviewer Asset Review Fee (or any component thereof) is calculated shall not exceed the rate then in effect and (iv) the resigning Asset Representations Reviewer shall be responsible for the reasonable costs and expenses of each other party to this Agreement and the Rating Agencies in connection with such transfer. Upon acceptance of such assignment and delegation, the purchaser or transferee shall provide notice to each party to this Agreement and then will be the successor asset representations reviewer hereunder.

(f)           With respect to any Delinquent Loan that is an Non-Serviced Mortgage Loan, to the extent any documents required by the Asset Representations Reviewer to complete a Test are missing or have not been received from the related Mortgage Loan Seller, the Asset Representations Reviewer shall request such document(s) from the related Non-Serviced Master Servicer (if such Non-Serviced Mortgage Loan is being serviced by a Non-Serviced Master Servicer) or the related Non-Serviced Special Servicer (if such Non-Serviced Serviced Mortgage Loan is being serviced by a Non-Serviced Special Servicer), the related Non-Serviced Trustee and the related Non-Serviced Certificate Administrator (and, in each case, such other party as contemplated under the related Non-Serviced PSA or related Intercreditor Agreement).

Section 12.02      Payment of Asset Representations Reviewer Fees and Expenses; Limitation of Liability. 

(a)          The Asset Representations Reviewer shall be paid a fee of $5,000 (the “Asset Representations Reviewer Upfront Fee”) on the Closing Date. As compensation for the performance of its routine duties, the Asset Representations Reviewer shall be paid a fee (the “Asset Representations Reviewer Fee”), payable monthly from amounts received in respect of each Mortgage Loan (including any Non-Serviced Mortgage Loan but excluding any Companion Loan) and REO Mortgage Loan and shall be equal to the product of a rate equal to 0.00047% per annum (the “Asset Representations Reviewer Fee Rate”) and the Stated Principal Balance of the Mortgage Loans and any REO Loans and shall be calculated in the same manner as interest is calculated on such Mortgage Loans and REO Loans.

(b)          As compensation for the performance of its duties hereunder, with respect to an individual Asset Review Trigger and the Mortgage Loans that are Delinquent Loans and are subject to an Asset Review (for purposes of this Section 12.02(b), “Subject Loans”), upon the

 -538-

completion of any Asset Review with respect to an individual Asset Review Trigger, the Asset Representations Reviewer shall be paid a fee equal to the sum of: (i) $15,000 multiplied by the number of Subject Loans, plus (ii) $1,500 per Mortgaged Property relating to the Subject Loans in excess of one Mortgaged Property per Subject Loan, plus (iii) $2,000 per Mortgaged Property relating to a Subject Loan subject to a ground lease, plus (iv) $1,000 per Mortgaged Property relating to a Subject Loan subject to a franchise agreement, hotel management agreement or hotel license agreement, subject, in the case of each of clauses (i) through (iv), to adjustments on the basis of the year-end Consumer Price Index for All Urban Consumers, or other similar index if the Consumer Price Index for All Urban Consumers is no longer calculated, for the year of the Closing Date and for the year of the occurrence of the Asset Review (the “Asset Representations Reviewer Asset Review Fee”). The Asset Representations Reviewer Asset Review Fee with respect to each Delinquent Loan shall be paid, in the first instance, by the related Mortgage Loan Seller within forty-five (45) days of receipt by the related Mortgage Loan Seller of a written invoice from the Asset Representations Reviewer. If the related Mortgage Loan Seller (x) is insolvent or (y) fails to pay such amount upon completion of any Asset Review and within 90 days of receiving an invoice from the asset representations reviewer, such fee shall be paid by the Trust following delivery by the Asset Representations Reviewer of evidence reasonably satisfactory to the Master Servicer or the Special Servicer, as applicable, of such insolvency or failure to pay such amount; provided, however, that a statement of non-payment by the Asset Representations Reviewer ninety (90) days after an itemized invoice is delivered by registered mail to the address listed in this Agreement for the related Mortgage Loan Seller, or to such other address as shall be provided by such Mortgage Loan Seller for delivery of notice in accordance with this Agreement, together with evidence of delivery or attempted delivery of such invoice and reasonable follow up by phone or email, shall constitute satisfactory evidence delivered by the Asset Representations Reviewer of such failure to pay such amount. Notwithstanding any payment of such fee by the Trust to the Asset Representations Reviewer, such fee will remain an obligation of the related Mortgage Loan Seller and the Special Servicer shall reasonably pursue remedies against such Mortgage Loan Seller to recover any such amounts to the extent paid by the Trust and the costs of doing so shall be a cost of the Trust. If the Asset Representations Reviewer Asset Review Fee is paid by the Trust pursuant to clause (y) above, the Trust shall be entitled to interest on such Asset Representations Reviewer Asset Review Fee at the advance rate from the related Mortgage Loan Seller and the Special Servicer shall be entitled to an additional fee equal to 40.0% of such Asset Representations Reviewer Asset Review Fee from the related Mortgage Loan Seller upon recovery of such amount), pursuant to Section 5 of the related Mortgage Loan Purchase Agreement.

(c)          Notwithstanding the foregoing, the Asset Representations Reviewer Asset Review Fee with respect to a Delinquent Loan shall be included in the Purchase Price for any Mortgage Loan that was the subject of a completed Asset Review and that is repurchased by a Mortgage Loan Seller, and such portion of the Purchase Price received shall be used to reimburse the Trust for such fees paid to the Asset Representations Reviewer pursuant to Section 12.02(b).

(d)          The Asset Representations Reviewer shall be liable in accordance herewith only to the extent of the obligations specifically imposed by this Agreement.

Section 12.03     Resignation of the Asset Representations Reviewer.   The Asset Representations Reviewer may resign and be discharged from its obligations hereunder by giving

 -539-

written notice thereof to the other parties to this Agreement and each Rating Agency. Upon such notice of resignation, the Depositor shall promptly appoint a successor asset representations reviewer that is an Eligible Asset Representations Reviewer. No resignation of the Asset Representations Reviewer shall be effective until a successor asset representations reviewer that is an Eligible Asset Representations Reviewer has been appointed and accepted the appointment. If no successor asset representations reviewer shall have been so appointed and have accepted appointment within 30 days after the giving of such notice of resignation, the resigning Asset Representations Reviewer may petition any court of competent jurisdiction for the appointment of a successor asset representations reviewer that is an Eligible Asset Representations Reviewer. The Asset Representations Reviewer will bear all reasonable costs and expenses of each other party hereto and each Rating Agency in connection with its resignation.

Section 12.04     Restrictions of the Asset Representations Reviewer.   Neither the Asset Representations Reviewer nor any of its Affiliates shall make any investment in any Class of Certificates; provided, however, that such prohibition shall not apply to (i) riskless principal transactions effected by a broker dealer Affiliate of the Asset Representations Reviewer or (ii) investments by an Affiliate of the Asset Representations Reviewer if the Asset Representations Reviewer and such Affiliate maintain policies and procedures that (A) segregate personnel involved in the activities of the Asset Representations Reviewer under this Agreement from personnel involved in such Affiliate’s investment activities and (B) prevent such Affiliate and its personnel from gaining access to information regarding the Trust and the Asset Representations Reviewer and its personnel from gaining access to such Affiliate’s information regarding its investment activities.

Section 12.05     Termination of the Asset Representations Reviewer.  

(a)          An “Asset Representations Reviewer Termination Event” means any one of the following events whether it shall be voluntary or involuntary or be effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body:

(i)           any failure by the Asset Representations Reviewer to observe or perform in any material respect any of its covenants or agreements or the material breach of any of its representations or warranties under this Agreement, which failure shall continue unremedied for a period of 30 days after the date on which written notice of such failure, requiring the same to be remedied, shall have been given to the Asset Representations Reviewer by the Trustee or to the Asset Representations Reviewer and the Trustee by the Holders of Certificates having at least 25% of the Pooled Voting Rights of all then-outstanding Certificates; provided that if such failure is capable of being cured and the Asset Representations Reviewer certifies to the other parties to this Agreement that it is diligently pursuing such cure, such 30 day period shall be extended by an additional 30 days;

(ii)          any failure by the Asset Representations Reviewer to perform in any material respect any of its obligations hereunder in accordance with the Asset Review Standard which failure shall continue unremedied for a period of 30 days after the date of

 -540-

written notice of such failure, requiring the same to be remedied, is given to the Asset Representations Reviewer by any party to this Agreement;

(iii)         any failure by the Asset Representations Reviewer to be an Eligible Asset Representations Reviewer, which failure shall continue unremedied for a period of 30 days after the date of written notice of such failure, requiring the same to be remedied, is given to the Asset Representations Reviewer by any party to this Agreement;

(iv)         a decree or order of a court or agency or supervisory authority having jurisdiction in the premises in an involuntary case under any present or future federal or state bankruptcy, insolvency or similar law for the appointment of a conservator or receiver or liquidator in any insolvency, readjustment of debt, marshaling of assets and liabilities or similar proceedings, or for the winding-up or liquidation of its affairs, shall have been entered against the Asset Representations Reviewer, and such decree or order shall have remained in force undischarged or unstayed for a period of 60 days;

(v)          the Asset Representations Reviewer shall consent to the appointment of a conservator or receiver or liquidator or liquidation committee in any insolvency, readjustment of debt, marshaling of assets and liabilities, voluntary liquidation, or similar proceedings of or relating to the Asset Representations Reviewer or of or relating to all or substantially all of its property; or

(vi)       the Asset Representations Reviewer shall admit in writing its inability to pay its debts generally as they become due, file a petition to take advantage of any applicable insolvency or reorganization statute, make an assignment for the benefit of its creditors, or voluntarily suspend payment of its obligations.

Upon receipt by the Certificate Administrator (which shall be simultaneously delivered by the Certificate Administrator to the Asset Representations Reviewer) of written notice of the occurrence of any Asset Representations Reviewer Termination Event, the Certificate Administrator shall promptly provide written notice to all Pooled Certificateholders in accordance with the notice distribution procedures described in Section 12.01(a), unless the Certificate Administrator has received written notice that such Asset Representations Reviewer Termination Event has been remedied. If an Asset Representations Reviewer Termination Event shall occur then, and in each and every such case, so long as such Asset Representations Reviewer Termination Event shall not have been remedied, either the Trustee (i) may or (ii) upon the written direction of holders of Corresponding Certificates evidencing not less than 25% of the Pooled Voting Rights of each Class of Pooled Regular Interests (other than the Class X Regular Interests) (without regard to the application of any Cumulative Appraisal Reduction Amounts), the Trustee shall, terminate all of the rights and obligations of the Asset Representations Reviewer under this Agreement, other than rights and obligations accrued prior to such termination (including the right to receive all amounts accrued and owing to it under this Agreement) and other than indemnification rights (arising out of events occurring prior to such termination), by notice in writing to the Asset Representations Reviewer. The Asset Representations Reviewer is required to bear all reasonable costs and expenses of each other party to this Agreement in connection with its termination due to an Asset Representations Reviewer Termination Event. Notwithstanding anything herein to the contrary, the Depositor

 -541-

and each Sponsor shall have the right, but not the obligation, to notify the Certificate Administrator and the Trustee of any Asset Representations Reviewer Termination Event of which it becomes aware.

(b)          Upon (i) the written direction of the Pooled Certificateholders evidencing not less than 25% of the Pooled Voting Rights (without regard to the application of any Cumulative Appraisal Reduction Amounts) requesting a vote to terminate and replace the Asset Representations Reviewer with a proposed successor asset representations reviewer that is an Eligible Asset Representations Reviewer and (ii) payment by such Holders to the Certificate Administrator of the reasonable fees and expenses to be incurred by the Certificate Administrator in connection with administering such vote, the Certificate Administrator shall promptly provide written notice thereof to the Asset Representations Reviewer and to all Pooled Certificateholders by (i) posting such notice on its internet website, and (ii) mailing such notice to all Pooled Certificateholders at their addresses appearing in the Certificate Register and to the Asset Representations Reviewer. Upon the written direction of the Pooled Certificateholders evidencing at least 75% of a Pooled Certificateholder Quorum (without regard to the application of any Cumulative Appraisal Reduction Amounts), the Trustee shall terminate all of the rights and obligations of the Asset Representations Reviewer under this Agreement (other than any rights or obligations that accrued prior to the date of such termination and other than indemnification rights arising out of events occurring prior to such termination) by notice in writing to the Asset Representations Reviewer. As between the Asset Representations Reviewer, on the one hand, and the Pooled Certificateholders, on the other, the Pooled Certificateholders shall be entitled in their sole discretion to vote for the termination or not vote for the termination of the Asset Representations Reviewer. In the event that the Pooled Certificateholders entitled to at least 75% of a Pooled Certificateholder Quorum (without regard to the application of any Cumulative Appraisal Reduction Amounts) elect to remove the Asset Representations Reviewer without cause and appoint a successor, the successor asset representations reviewer will be responsible for all expenses necessary to effect the transfer of responsibilities from its predecessor.

(c)          On or after the receipt by the Asset Representations Reviewer of written notice of termination, subject to this Section 12.05, all of its authority and power under this Agreement shall be terminated and, without limitation, the terminated Asset Representations Reviewer shall execute any and all documents and other instruments, and do or accomplish all other acts or things reasonably necessary or appropriate to effect the purposes of such notice of termination. As soon as practicable, but in no event later than 15 Business Days after (1) the Asset Representations Reviewer resigns pursuant to Section 12.03 of this Agreement or (2) the Trustee delivers such written notice of termination to the Asset Representations Reviewer, the Trustee shall appoint a successor asset representations reviewer that is an Eligible Asset Representations Reviewer. The Trustee shall provide written notice of the appointment of an Asset Representations Reviewer to the Master Servicer, the Special Servicer, the Operating Advisor, the Certificate Administrator, the Directing Certificateholder, the Directing Holder and each Certificateholder within one Business Day of such appointment.

The Asset Representations Reviewer shall be at all times an Eligible Asset Representations Reviewer and if the Asset Representations Reviewer ceases to be an Eligible Asset Representations Reviewer, the Asset Representations Reviewer shall immediately notify

 -542-

the Master Servicer, the Special Servicer, the Trustee, the Operating Advisor, the Certificate Administrator and the Directing Holder of such disqualification and immediately resign under Section 12.03 of this Agreement and the Trustee shall appoint a successor asset representations reviewer subject to and in accordance with this Section 12.05. Notwithstanding the foregoing, if the Trustee is unable to find a successor asset representations reviewer within 30 days of the termination of the Asset Representations Reviewer, the Depositor shall be permitted to find a replacement. The Trustee shall not be liable for any failure to identify and appoint a successor asset representations reviewer for so long as the Trustee uses commercially reasonable efforts to conduct a search for a successor asset representations reviewer and such failure is not a result of the Trustee’s negligence, bad faith or willful misconduct in the performance of its obligations hereunder.

(d)          Upon any termination of the Asset Representations Reviewer and appointment of a successor to the Asset Representations Reviewer, the Trustee shall, as soon as possible, give written notice thereof to the Special Servicer, the Master Servicer, the Certificate Administrator (who shall, as soon as possible, give written notice thereof to the Certificateholders), the Operating Advisor, the Sponsors, the Depositor and, prior to the occurrence and continuance of a Consultation Termination Event, the Directing Holder and each Rating Agency. In the event that the Asset Representations Reviewer is terminated, all of its rights and obligations under this Agreement shall terminate, other than any rights or obligations that accrued prior to the date of such termination (including the right to receive all amounts accrued and owing to it under this Agreement) and other than indemnification rights (arising out of events occurring prior to such termination).

(i)           reduce in any manner the amount of, or delay the timing of, payments received on the Mortgage Loans or the Trust Subordinate Companion Loans that are required to be distributed on a Certificate of any class without the consent of the Holder of the Certificate or which are required to be distributed to a Companion Holder without the consent of such Companion Holder; or

(ii)          reduce the aforesaid percentage of Certificates of any Class the Holders of which are required to consent to any such amendment or remove the requirement to obtain consent of any Companion Holder or Holder of Loan-Specific Certificates, in any such case, without the consent of the Holders of all Certificates of such Class then-outstanding or such Companion Holders, as applicable; or

(iii)         adversely affect the Voting Rights of any Class of Certificates without the consent of the Holders of all Certificates of such Class then outstanding; or

(iv)         change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations or rights of any Mortgage Loan Seller under such Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan Seller as a third party beneficiary hereunder, without the consent of such Mortgage Loan Seller; or

(c)          Notwithstanding the foregoing, none of the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Depositor, the Master Servicer nor the Special Servicer will be required to consent to any amendment hereto without having first received an Opinion of Counsel (at the Trust’s expense) to the effect that such amendment is permitted hereunder, that all conditions precedent have been satisfied and that such amendment or the exercise of any power granted to the Master Servicer, the Special Servicer, the Depositor, the Trustee, the Certificate Administrator, the Operating Advisor, the Asset Representations Reviewer or any other specified person in accordance with such amendment will not result in the imposition of a tax on any portion of the Trust Fund or any Trust REMIC, or cause any Trust REMIC to fail to qualify as a REMIC or cause the Grantor Trust to fail to qualify as a grantor trust under the relevant provisions of the Code. Furthermore, no amendment to this Agreement may be made that changes in any material adverse respect the rights of any Class of Loan-Specific Certificates without the consent of such Class and no amendment to this Agreement may be made that changes any provisions specifically required to be included in this Agreement by the Non-Serviced Intercreditor Agreement without the consent of the holder of the related Non-Serviced Companion Loan(s).

(e)          It shall not be necessary for the consent of Certificateholders under this Section 13.01 to approve the particular form of any proposed amendment, but it shall be sufficient if such consent shall approve the substance thereof. The manner of obtaining such consents and of evidencing the authorization of the execution thereof by Certificateholders shall be subject to such reasonable regulations as the Certificate Administrator may prescribe.

(f)           The Trustee and the Certificate Administrator shall not be obligated to enter into any amendment pursuant to this Section 13.01 that affects its rights, duties and immunities under this Agreement or otherwise.

(g)          The cost of any Opinion of Counsel to be delivered pursuant to Section 13.01(a) or Section 13.01(c) and the cost of any amendment entered into hereunder shall be borne by the Person seeking the related amendment, except that if the Master Servicer, the Certificate Administrator or the Trustee requests any amendment of this Agreement in furtherance of the rights and interests of Certificateholders, the cost of any Opinion of Counsel required in connection therewith pursuant to Section 13.01(a) or Section 13.01(c) shall be payable out of the Collection Account.

(h)          The Servicing Standard shall not be amended unless each Rating Agency provides Rating Agency Confirmation and, with respect to any class of Serviced Companion Loan Securities, the applicable rating agencies provide a confirmation that such action will not

 -547-

result in the downgrade, withdrawal or qualification of its then-current ratings, if any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant to Section 3.25).

(i)           To the extent the Operating Advisor, the Trustee, the Certificate Administrator, the Master Servicer, the Special Servicer, the Asset Representations Reviewer or Depositor obtains an Opinion of Counsel as provided for in Section 13.01(c) in connection with executing any amendment to this Agreement, such party shall be deemed not to have acted negligently in connection with entering into such amendment for purposes of availing itself of any indemnity provided to such party under this Agreement.

(j)           Notwithstanding any other provision of this Agreement, for purposes of the giving or withholding of consents pursuant to this Section 13.01, Certificates registered in the name of the Depositor or any Affiliate of the Depositor shall be entitled to the same Voting Rights with respect to matters described above as they would if any other Person held such Certificates, so long as neither the Depositor nor any of its Affiliates is performing servicing duties with respect to any of the Mortgage Loans or the Trust Subordinate Companion Loans.

(k)          This Agreement may not be amended without the consent of any holder of an AB Subordinate Companion Loan if such amendment would materially and adversely affect the rights of such Companion Holder hereunder. With respect to any Serviced Whole Loan, in connection with any amendment of this Agreement, the party requesting such amendment shall provide written notice (which may be by e-mail) of such proposed amendment to each Other Depositor (and counsel thereto) and the Other Certificate Administrator of each Other Securitization no later than three (3) Business Days prior to the date of effectiveness of such amendment, and, on the date of effectiveness of such amendment to this Agreement, the Certificate Administrator shall provide a copy of such amendment in an EDGAR-compatible format to each Other Depositor (and counsel thereto) and the Other Certificate Administrator of each Other Securitization.

(b)          For the purpose of facilitating the recordation of this Agreement as herein provided and for other purposes, this Agreement may be executed simultaneously in any number of counterparts, each of which counterparts shall be deemed to be an original, and such counterparts shall constitute but one and the same instrument. Delivery of an executed counterpart of a signature page of this Agreement in Portable Document Format (PDF) or by

Section 13.03     Limitation on Rights of Certificateholders.  (a) The death or incapacity of any Certificateholder shall not operate to terminate this Agreement or the Trust, nor entitle such Certificateholder’s legal representatives or heirs to claim an accounting or to take any action or proceeding in any court for a partition or winding up of the Trust, nor otherwise affect the rights, obligations and liabilities of the parties hereto or any of them.

(b)          No Certificateholder shall have any right to vote (except as expressly provided for herein) or in any manner otherwise control the operation and management of the Trust, or the obligations of the parties hereto, nor shall anything herein set forth, or contained in the terms of the Certificates, be construed so as to constitute the Certificateholders from time to time as partners or members of an association; nor shall any Certificateholder be under any liability to any third party by reason of any action taken by the parties to this Agreement pursuant to any provision hereof.

It is understood and intended, and expressly covenanted by each Certificateholder with every other Certificateholder and the Trustee, that no one or more Holders of Certificates shall have any right in any manner whatsoever by virtue of any provision of this Agreement or the Certificates to affect, disturb or prejudice the rights of the Holders of any other of such Certificates, or to obtain or seek to obtain priority over or preference to any other such Holder, which priority or preference is not otherwise provided for herein, or to

 -555-

Section 13.07     Grant of a Security Interest.   The Depositor intends that the conveyance of the Depositor’s right, title and interest in and to the Mortgage Loans and the Trust Subordinate Companion Loans pursuant to this Agreement shall constitute a sale and not a pledge of security for a loan.

The Depositor also intends and agrees that, in such event, (i) the Depositor shall be deemed to have granted to the Trustee (in such capacity) a first priority security interest in the Depositor’s entire right, title and interest in and to the assets comprising the Trust Fund, including without limitation, the Mortgage Loans and the Trust Subordinate Companion Loans, all principal and interest received or receivable with respect to the Mortgage Loans and the Trust Subordinate Companion Loans (other than principal and interest payments due and payable prior to the Cut-off Date and Principal Prepayments received prior to the Cut-off Date), all amounts held from time to time in the Collection Account, the Distribution Accounts, the Gain-on-Sale Reserve Account, the Interest Reserve Account and, if established, the REO Account, and all reinvestment earnings on such amounts, and all of the Depositor’s right, title and interest in and to the proceeds of any title, hazard or other Insurance Policies related to such Mortgage Loans and Trust Subordinate Companion Loans and (ii) this Agreement shall constitute a security agreement under applicable law. The Depositor shall file or cause to be filed, as a precautionary filing, a UCC Financing Statement in all appropriate locations promptly following the initial issuance of the Certificates to reflect the assignments made by the Mortgage Loan Sellers to the Depositor (and the Trustee) and by the Depositor to the Trustee (copies of which shall be delivered by the Depositor to the Certificate Administrator shall, at the expense of the Depositor (to the extent reasonable), no later than 10 days following the Closing Date), and the Certificate Administrator shall prepare and file continuation statements with respect thereto, in each case in the six month period prior to every fifth anniversary of the date of the initial UCC Financing Statement. The Depositor shall cooperate in a reasonable manner with the Certificate Administrator in the preparation and filing of such continuation statements. This Section 13.07 shall constitute notice to the Certificate Administrator and the Trustee pursuant to any of the requirements of the applicable UCC.

Section 13.08     Successors and Assigns; Third Party Beneficiaries.   (a) The provisions of this Agreement shall be binding upon and inure to the benefit of the respective successors and assigns of the parties hereto, and all such provisions shall inure to the benefit of the Certificateholders. Each Mortgage Loan Seller (and its respective agents), each Companion Holder (and its respective agents), each Underwriter, each depositor of a Regulation AB Companion Loan Securitization and each Initial Purchaser is an intended third-party beneficiary to this Agreement in respect of the respective rights afforded it hereunder. No other person, including, without limitation, any Mortgagor, shall be entitled to any benefit or equitable right, remedy or claim under this Agreement.

(b)          Each Serviced Companion Noteholder shall be a third-party beneficiary to this Agreement in respect to the rights afforded it hereunder. Each of the Other Servicers and the Other Trustees shall be a third-party beneficiary to this Agreement in respect to all provisions herein expressly relating to compensation, reimbursement or indemnification of such Other Servicer and Other Trustee, and any provisions regarding reimbursement or advances or interest thereon to such Other Servicer or Other Trustee.

 -556-

(c)          Each of the applicable Non-Serviced Trustee, Non-Serviced Master Servicer, Non-Serviced Special Servicer and any Non-Serviced Trust holding a related Non-Serviced Companion Loan, shall be a third-party beneficiary to this Agreement in respect to its rights as specifically provided for herein and under the applicable Non-Serviced Intercreditor Agreement.

(d)          Subject to Section 2.03(k)(ii), Section 2.03(l)(iv) and Section 2.03(l)(v), any Requesting Certificateholder shall be an express third-party beneficiary to this Agreement for purposes of exercising rights under Section 2.03(k) through Section 2.03(o).

Section 13.09      Article and Section Headings.  The article and section headings herein are for convenience of reference only, and shall not limit or otherwise affect the meaning hereof.

Section 13.10     Notices to the Rating Agencies.   (a) The Certificate Administrator shall use reasonable efforts promptly to provide notice to the 17g-5 Information Provider for posting on the 17g-5 Information Provider’s Website pursuant to Section 3.13(c), (and the related 17g-5 information provider for any class of Serviced Companion Loan Securities to the extent applicable to any Serviced Whole Loan) with respect to each of the following of which it has actual knowledge:

(i)           any material change or amendment to this Agreement;

(ii)          the occurrence of a Servicer Termination Event that has not been cured;

(iii)         any Loss of Value Payments;

(iv)         the resignation or termination of the Certificate Administrator, the Master Servicer, the Asset Representations Reviewer or the Special Servicer; and

(v)          any additional lease to an anchor tenant or termination of any existing lease to an anchor tenant at retail properties for any Mortgage Loan or Trust Subordinate Companion Loan with a Stated Principal Balance that is equal to or greater than the lesser of (1) an amount greater than 5% of the then-aggregate outstanding principal balances of the Mortgage Loans and (2) $35,000,000;

(vi)         any material damage to any Mortgaged Property;

(vii)        any modifications to an Intercreditor Agreement;

(viii)       any assumption with respect to a Mortgage Loan or Trust Subordinate Companion Loan;

(ix)         any incurrence by a Mortgagor of additional debt; and

(x)          any release or substitution of any Mortgaged Property.

(c)          The Certificate Administrator shall promptly furnish notice to the 17g-5 Information Provider for posting on the 17g-5 Information Provider’s Website pursuant to Section 3.13(c), and thereafter to the Rating Agencies of (i) any change in the location of the Distribution Accounts and (ii) the final payment to any Class of Certificateholders.

(d)       The Trustee, the Certificate Administrator, the Master Servicer and the Special Servicer, as applicable, shall furnish to the 17g-5 Information Provider for posting on the 17g-5 Information Provider’s Website pursuant to Section 3.13(c), and thereafter to each Rating Agency (and any rating agency for any class of Serviced Companion Loan Securities to the extent applicable to any Serviced Whole Loan) with respect to each Mortgage Loan (other than any Non-Serviced Mortgage Loan) and Trust Subordinate Companion Loan such information as any Rating Agency shall reasonably request and which the Trustee, the Certificate Administrator, the Master Servicer or the Special Servicer, can reasonably provide in accordance with applicable law and without waiving any attorney-client privilege relating to such information or violating the terms of this Agreement or any Mortgage Loan or Trust Subordinate Companion Loan. The Trustee, the Certificate Administrator, the Master Servicer and the Special Servicer, as applicable, may include any reasonable disclaimer it deems appropriate with respect to such information. Notwithstanding anything to the contrary herein, nothing in this Section 13.10 shall require a party to provide duplicative notices or copies to the Rating Agencies with respect to any of the above listed items. In connection with the delivery by the Master Servicer or the Special Servicer to the 17g-5 Information Provider of any information, report, notice or document for posting to the 17g-5 Information Provider’s Website, the 17g-5 Information Provider shall notify the Master Servicer or the Special Servicer when such information, report, notice or document has been posted. The Master Servicer or the Special Servicer, as the case may be, may, but shall not be obligated to send such information, report, notice or document to the applicable Rating Agency so long as such information, report, notice or document (i) was previously provided to the 17g-5 Information Provider or (ii) is simultaneously provided, by 2:00 p.m. (New York City time) on any Business Day, to the 17g-5 Information Provider.

This certifies that [           ] is the registered owner of a beneficial ownership interest in a Trust Fund, including the distributions to be made with respect to the Class A-1 Certificates. The Trust Fund, described more fully below, consists primarily of a pool of Mortgage Loans secured by first liens on commercial and multifamily properties and subordinate interests in two subordinate companion loans (the “Trust Subordinate Companion Loans”) held in trust by the Trustee and serviced by the Master Servicer. The Trust Fund was created, and the Mortgage Loans and the Trust Subordinate Companion Loans are to be serviced, pursuant to the Pooling and Servicing Agreement (as defined below). The Holder of this Certificate, by virtue of the acceptance hereof, assents to the terms, provisions and conditions of the Pooling and Servicing Agreement and is bound thereby. In the event that there is any conflict between any provision of this Certificate and any provision of the Pooling and Servicing Agreement, such provision of this Certificate shall be superseded to the extent of such inconsistency. Also issued under the Pooling and Servicing Agreement are the Class A-2, Class A-3, Class A-4, Class A-5, Class A-

This Certificate is issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of November 1, 2017 (the “Pooling and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities Corp., as Depositor, Wells Fargo Bank, National Association, as Certificate Administrator and as Trustee, Park Bridge Lender Services LLC, as Operating Advisor and as Asset Representations Reviewer, KeyBank National Association, as Master Servicer, and CWCapital Asset Management LLC, as Special Servicer. To the extent not defined herein, capitalized terms used herein shall have the meanings assigned thereto in the Pooling and Servicing Agreement.

This Certificate represents beneficial ownership of a “regular interest” in a “real estate mortgage investment conduit,” as those terms are defined, respectively, in Sections 860G(a)(1) and 860D of the Internal Revenue Code of 1986, as amended.

The Certificate Administrator makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates, the Mortgage Loans or the Trust Subordinate Companion Loans and has executed this Certificate in its limited capacity as Certificate Administrator under the Pooling and Servicing Agreement.

Pursuant to the terms of the Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution on any Certificate), on the 4th Business Day following the determination date of each month, commencing in December 2017 (each such date, a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related Record Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this Certificate) of that portion of the aggregate amount of principal and interest then distributable, if any, allocable to the Class A-1 Certificates for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement. Holders of this Certificate may be entitled to Yield Maintenance Charges, as provided in the Pooling and Servicing Agreement.

Interest accrued on this Certificate during an Interest Accrual Period, plus the aggregate unpaid Interest Shortfall with respect to this Certificate, if any, will be payable on the related Distribution Date to the extent provided in the Pooling and Servicing Agreement. The “Interest Accrual Period” with respect to any Distribution Date and with respect to the Class A-1 Certificates is the calendar month immediately preceding the month in which such Distribution Date occurs and is assumed to consist of 30 days.

All distributions (other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons in whose names the Certificates are registered at the close of business on each Record Date, which will be the close of business on the last Business Day of the month immediately preceding the month in which such Distribution Date occurs.

A-1-4

Distributions are required to be made (a) by wire transfer of immediately available funds to the account of such Certificateholder at a bank or other entity having appropriate facilities therefor, if such Certificateholder provided the Certificate Administrator with written wiring instructions no less than five Business Days prior to the related Record Date (which wiring instructions may be in the form of a standing order applicable to all subsequent Distribution Dates), or otherwise (b) by check mailed to such Certificateholder at its address in the Certificate Register. The final distribution on each Certificate will be made in like manner, but only upon presentment and surrender of such Certificate at the offices of the Certificate Registrar or such other location specified in the notice to Certificateholders of such final distribution.

Any funds not distributed to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure of such Certificateholders to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited to the account or accounts of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been given pursuant to Section 4.01(l) of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within six months after the time specified in such notice, the Certificate Administrator shall mail a second notice to the remaining non tendering Certificateholders to surrender their Certificates for cancellation in order to receive the final distribution with respect thereto. If within one year after the second notice all such Certificates shall not have been surrendered for cancellation, the Certificate Administrator, directly or through an agent, shall take such steps to contact the remaining non tendering Certificateholders concerning the surrender of their Certificates as it shall deem appropriate and subject to escheatment and other applicable laws. The costs and expenses of holding such funds in trust and of contacting such Certificateholders following the first anniversary of the delivery of such second notice to the non-tendering Certificateholders shall be paid out of such funds. No interest shall accrue or be payable to any Certificateholder on any amount held in trust under the Pooling and Servicing Agreement by the Certificate Administrator as a result of such Certificateholder’s failure to surrender its Certificate(s) for final payment thereof in accordance with Section 4.01(l) of the Pooling and Servicing Agreement.

This Certificate is limited in right of payment to, among other things, certain collections and recoveries in respect of the Mortgage Loans, as more specifically set forth herein and in the Pooling and Servicing Agreement.

As provided in the Pooling and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject to the Pooling and Servicing Agreement (including any Qualified Substitute Mortgage Loan replacing a removed Mortgage Loan) and the Trust Subordinate Companion Loans, together with the Mortgage Files relating thereto (subject to, in the case of a Serviced Whole Loan, the interests of the related Serviced Companion Noteholder in the related Mortgage File); (ii) all scheduled or unscheduled payments on or collections in respect of the Mortgage Loans and the Trust Subordinate Companion Loans due after the Cut-off Date (or with respect to a Qualified Substitute Mortgage Loan, the Due Date in the month of substitution); (iii) any REO Property (to the extent of the Trust’s interest therein) or the Trust’s beneficial interest in the Mortgaged Property securing a Non Serviced Whole Loan acquired under the related Non-Serviced PSA; (iv) all revenues received in respect of any REO Property (to the extent of the Trust’s interest therein); (v) the Master Servicer’s, the Special Servicer’s, the Certificate Administrator’s and the Trustee’s rights under the insurance policies

A-1-5

with respect to the Mortgage Loans and the Trust Subordinate Companion Loans required to be maintained pursuant to the Pooling and Servicing Agreement and any proceeds thereof (to the extent of the Trust’s interest therein); (vi) any Assignment of Leases and any security agreements (to the extent of the Trust’s interest therein); (vii) any letters of credit, indemnities, guaranties or lease enhancement policies given as additional security for any related Mortgage Loans or Trust Subordinate Companion Loans (to the extent of the Trust’s interest therein); (viii) all assets deposited in the Loss of Value Reserve Fund and the Servicing Accounts (to the extent of the Trust’s interest therein), amounts on deposit in the Collection Account (to the extent of the Trust’s interest therein), the Lower-Tier REMIC Distribution Account, the Upper-Tier REMIC Distribution Account, the Trust Subordinate Companion Loan REMIC Distribution Accounts, the Regular Interest Distribution Account, the Excess Interest Distribution Account, the Interest Reserve Account, the Gain-on-Sale Reserve Account (to the extent of the Trust’s interest therein) and any REO Account (to the extent of the Trust’s interest therein), including any reinvestment income, as applicable; (ix) any Environmental Indemnity Agreements (to the extent of the Trust’s interest therein); (x) the rights and remedies of the Depositor under each Mortgage Loan Purchase Agreement (to the extent transferred to the Trustee); (xi) the Lower-Tier Regular Interests; (xii) the Trust Subordinate Companion Loan REMIC Regular Interests; and (xiii) the proceeds of the foregoing (other than any interest earned on deposits in the lock-box accounts, cash collateral accounts, escrow accounts and any reserve accounts, to the extent such interest belongs to the related Mortgagor).

This Certificate does not purport to summarize the Pooling and Servicing Agreement, and reference is made to the Pooling and Servicing Agreement for the interests, rights, benefits, obligations and duties evidenced hereby, and the limitations thereon, and the rights, duties and immunities of the Certificate Administrator and Trustee.

As provided in the Pooling and Servicing Agreement, subject to certain restrictions on transfer set forth therein, upon surrender for registration of transfer of any Certificate, the Certificate Administrator shall execute, authenticate and deliver, in the name of the designated transferee or transferees, one or more new Certificates in authorized denominations, in like aggregate interest and of the same Class.

Prior to due presentation of this Certificate for registration of transfer, the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Certificate Registrar, and any agent of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate Registrar may treat the Person in whose name any Certificate is registered as the owner of such Certificate for the purpose of receiving distributions as provided in the Pooling and Servicing Agreement and for all other purposes whatsoever, and none of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Certificate Registrar, or any agent of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate Registrar shall be affected by any notice to the contrary.

(ix) to modify the procedures of the Pooling and Servicing Agreement relating to compliance with Rule 17g-5 of the Exchange Act; provided that such amendment shall not adversely affect in any material respects the interests of any Certificateholders (including, for the avoidance of doubt, any Holders of a VRR Interest, a Y&L Towers VRR Interest or a Standard Highline VRR Interest), as evidenced by (x) an Opinion of Counsel or (y) if any Certificate is then rated, receipt of Rating Agency Confirmation from each Rating Agency rating such Certificates; and provided, further, that the Certificate Administrator shall give notice of any such amendment to the 17g-5 Information Provider for posting to the 17g-5 Information Provider’s Website pursuant to Section 3.13(c) of the Pooling and Servicing Agreement and the Certificate Administrator shall post such notice to the Certificate Administrator’s Website;

Notwithstanding the foregoing, no such amendment (A) may change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations of any Mortgage Loan Seller under any Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller or (B) may materially and adversely affect the holders of a Companion Loan without such Companion Holder’s consent.

A-1-9

The Pooling and Servicing Agreement may also be amended from time to time by the parties thereto with the consent of the Holders of Certificates of each Class affected by such amendment (including, for the avoidance of doubt, any Holders of the VRR Interest, the Y&L Towers VRR Interest or the Standard Highline VRR Interest to the extent any such amendment would adversely affect the rights of such Certificateholders) evidencing in the aggregate not less than a majority of the aggregate Percentage Interests constituting the Class for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of the Pooling and Servicing Agreement or of modifying in any manner the rights of the Holders of Certificates of such Class; provided, however, that no such amendment shall:

(i) reduce in any manner the amount of, or delay the timing of, payments received on the Mortgage Loans or the Trust Subordinate Companion Loans that are required to be distributed on a Certificate of any class without the consent of the Holder of the Certificate or which are required to be distributed to a Companion Holder without the consent of such Companion Holder; or

(ii) reduce the aforesaid percentage of Certificates of any Class the Holders of which are required to consent to any such amendment or remove the requirement to obtain consent of any Companion Holder or Holder of Loan-Specific Certificates, in any such case, without the consent of the Holders of all Certificates of such Class then-outstanding or such Companion Holders, as applicable; or

(iii) adversely affect the Voting Rights of any Class of Certificates without the consent of the Holders of all Certificates of such Class then outstanding; or

A-1-10

Notwithstanding the foregoing, none of the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Depositor, the Master Servicer nor the Special Servicer will be required to consent to any amendment to the Pooling and Servicing Agreement without having first received an Opinion of Counsel (at the Trust’s expense) to the effect that such amendment is permitted under the Pooling and Servicing Agreement, that all conditions precedent have been satisfied and that such amendment or the exercise of any power granted to the Master Servicer, the Special Servicer, the Depositor, the Trustee, the Certificate Administrator, the Operating Advisor, the Asset Representations Reviewer or any other specified person in accordance with such amendment will not result in the imposition of a tax on any portion of the Trust Fund or any Trust REMIC, or cause any Trust REMIC to fail to qualify as a REMIC or cause the Grantor Trust to fail to qualify as a grantor trust under the relevant provisions of the Code.

The Holders of the majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates may, in that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the Certificate Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage Loans (and all property acquired through exercise of remedies in respect of any related Mortgage Loan), the Trust Subordinate Companion Loans and the Trust’s portion of each REO Property remaining in the Trust Fund, and thereby effect termination of the Trust and early retirement of the then-outstanding Certificates, only on or after the first Distribution Date on which the aggregate Stated Principal Balances of the Mortgage Loans, the Trust Subordinate Companion Loans and the portion of any REO Loans held by the Trust is less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage Loans (solely for the purposes of this calculation, if such right is being exercised after December 2027 and the 237 East Fordham Road Mortgage Loan is still an asset of the Trust, then such Mortgage Loan will be excluded from the then-aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate Companion Loans and from the aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate Companion Loans as of the Cut-off Date) as set forth in the Pooling and Servicing Agreement.

Following the date on which the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class A-S, Class X-A, Class X-B, Class X-E, Class B and Class C Regular Interests have been reduced to zero (and provided that there is only one Holder (or multiple Holders acting in unanimity) of the then-outstanding Certificates (other than the Class Z and Class R Certificates)), the Sole Certificateholder shall have the right, with the consent of the Master Servicer, to exchange all of its Certificates (other than the Class Z and Class R Certificates) together with the payment or deemed payment of the Termination Purchase Amount for all of the Mortgage Loans, the Trust Subordinate Companion Loans and each REO Property remaining in the Trust Fund pursuant to the terms of the Pooling and Servicing Agreement.

The obligations created by the Pooling and Servicing Agreement and the Trust created thereby (other than the obligation of the Certificate Administrator to make payments to Certificateholders as provided for in the Pooling and Servicing Agreement), shall terminate upon reduction of the Certificate Balances of all the Certificates to zero (including, without limitation, any such final payment resulting from a termination of the Trust due to a sale of its property) pursuant to the terms of the Pooling and Servicing Agreement.

This certifies that [           ] is the registered owner of a beneficial ownership interest in a Trust Fund, including the distributions to be made with respect to the Class A-2 Certificates. The Trust Fund, described more fully below, consists primarily of a pool of Mortgage Loans secured by first liens on commercial and multifamily properties and subordinate interests in two subordinate companion loans (the “Trust Subordinate Companion Loans”) held in trust by the Trustee and serviced by the Master Servicer. The Trust Fund was created, and the Mortgage Loans and the Trust Subordinate Companion Loans are to be serviced, pursuant to the Pooling and Servicing Agreement (as defined below). The Holder of this Certificate, by virtue of the acceptance hereof, assents to the terms, provisions and conditions of the Pooling and Servicing Agreement and is bound thereby. In the event that there is any conflict between any provision of this Certificate and any provision of the Pooling and Servicing Agreement, such provision of this Certificate shall be superseded to the extent of such inconsistency. Also issued under the Pooling and Servicing Agreement are the Class A-1, Class A-3, Class A-4, Class A-5, Class A-

This Certificate is issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of November 1, 2017 (the “Pooling and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities Corp., as Depositor, Wells Fargo Bank, National Association, as Certificate Administrator and as Trustee, Park Bridge Lender Services LLC, as Operating Advisor and as Asset Representations Reviewer, KeyBank National Association, as Master Servicer, and CWCapital Asset Management LLC, as Special Servicer. To the extent not defined herein, capitalized terms used herein shall have the meanings assigned thereto in the Pooling and Servicing Agreement.

This Certificate represents beneficial ownership of a “regular interest” in a “real estate mortgage investment conduit,” as those terms are defined, respectively, in Sections 860G(a)(1) and 860D of the Internal Revenue Code of 1986, as amended.

The Certificate Administrator makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates, the Mortgage Loans or the Trust Subordinate Companion Loans and has executed this Certificate in its limited capacity as Certificate Administrator under the Pooling and Servicing Agreement.

Pursuant to the terms of the Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution on any Certificate), on the 4th Business Day following the determination date of each month, commencing in December 2017 (each such date, a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related Record Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this Certificate) of that portion of the aggregate amount of principal and interest then distributable, if any, allocable to the Class A-2 Certificates for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement. Holders of this Certificate may be entitled to Yield Maintenance Charges, as provided in the Pooling and Servicing Agreement.

Interest accrued on this Certificate during an Interest Accrual Period, plus the aggregate unpaid Interest Shortfall with respect to this Certificate, if any, will be payable on the related Distribution Date to the extent provided in the Pooling and Servicing Agreement. The “Interest Accrual Period” with respect to any Distribution Date and with respect to the Class A-2 Certificates is the calendar month immediately preceding the month in which such Distribution Date occurs and is assumed to consist of 30 days.

All distributions (other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons in whose names the Certificates are registered at the close of business on each Record Date, which will be the close of business on the last Business Day of the month immediately preceding the month in which such Distribution Date occurs.

A-2-4

Distributions are required to be made (a) by wire transfer of immediately available funds to the account of such Certificateholder at a bank or other entity having appropriate facilities therefor, if such Certificateholder provided the Certificate Administrator with written wiring instructions no less than five Business Days prior to the related Record Date (which wiring instructions may be in the form of a standing order applicable to all subsequent Distribution Dates), or otherwise (b) by check mailed to such Certificateholder at its address in the Certificate Register. The final distribution on each Certificate will be made in like manner, but only upon presentment and surrender of such Certificate at the offices of the Certificate Registrar or such other location specified in the notice to Certificateholders of such final distribution.

Any funds not distributed to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure of such Certificateholders to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited to the account or accounts of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been given pursuant to Section 4.01(l) of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within six months after the time specified in such notice, the Certificate Administrator shall mail a second notice to the remaining non tendering Certificateholders to surrender their Certificates for cancellation in order to receive the final distribution with respect thereto. If within one year after the second notice all such Certificates shall not have been surrendered for cancellation, the Certificate Administrator, directly or through an agent, shall take such steps to contact the remaining non tendering Certificateholders concerning the surrender of their Certificates as it shall deem appropriate and subject to escheatment and other applicable laws. The costs and expenses of holding such funds in trust and of contacting such Certificateholders following the first anniversary of the delivery of such second notice to the non-tendering Certificateholders shall be paid out of such funds. No interest shall accrue or be payable to any Certificateholder on any amount held in trust under the Pooling and Servicing Agreement by the Certificate Administrator as a result of such Certificateholder’s failure to surrender its Certificate(s) for final payment thereof in accordance with Section 4.01(l) of the Pooling and Servicing Agreement.

This Certificate is limited in right of payment to, among other things, certain collections and recoveries in respect of the Mortgage Loans, as more specifically set forth herein and in the Pooling and Servicing Agreement.

As provided in the Pooling and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject to the Pooling and Servicing Agreement (including any Qualified Substitute Mortgage Loan replacing a removed Mortgage Loan) and the Trust Subordinate Companion Loans, together with the Mortgage Files relating thereto (subject to, in the case of a Serviced Whole Loan, the interests of the related Serviced Companion Noteholder in the related Mortgage File); (ii) all scheduled or unscheduled payments on or collections in respect of the Mortgage Loans and the Trust Subordinate Companion Loans due after the Cut-off Date (or with respect to a Qualified Substitute Mortgage Loan, the Due Date in the month of substitution); (iii) any REO Property (to the extent of the Trust’s interest therein) or the Trust’s beneficial interest in the Mortgaged Property securing a Non Serviced Whole Loan acquired under the related Non-Serviced PSA; (iv) all revenues received in respect of any REO Property (to the extent of the Trust’s interest therein); (v) the Master Servicer’s, the Special Servicer’s, the Certificate Administrator’s and the Trustee’s rights under the insurance policies

A-2-5

with respect to the Mortgage Loans and the Trust Subordinate Companion Loans required to be maintained pursuant to the Pooling and Servicing Agreement and any proceeds thereof (to the extent of the Trust’s interest therein); (vi) any Assignment of Leases and any security agreements (to the extent of the Trust’s interest therein); (vii) any letters of credit, indemnities, guaranties or lease enhancement policies given as additional security for any related Mortgage Loans or Trust Subordinate Companion Loans (to the extent of the Trust’s interest therein); (viii) all assets deposited in the Loss of Value Reserve Fund and the Servicing Accounts (to the extent of the Trust’s interest therein), amounts on deposit in the Collection Account (to the extent of the Trust’s interest therein), the Lower-Tier REMIC Distribution Account, the Upper-Tier REMIC Distribution Account, the Trust Subordinate Companion Loan REMIC Distribution Accounts, the Regular Interest Distribution Account, the Excess Interest Distribution Account, the Interest Reserve Account, the Gain-on-Sale Reserve Account (to the extent of the Trust’s interest therein) and any REO Account (to the extent of the Trust’s interest therein), including any reinvestment income, as applicable; (ix) any Environmental Indemnity Agreements (to the extent of the Trust’s interest therein); (x) the rights and remedies of the Depositor under each Mortgage Loan Purchase Agreement (to the extent transferred to the Trustee); (xi) the Lower-Tier Regular Interests; (xii) the Trust Subordinate Companion Loan REMIC Regular Interests; and (xiii) the proceeds of the foregoing (other than any interest earned on deposits in the lock-box accounts, cash collateral accounts, escrow accounts and any reserve accounts, to the extent such interest belongs to the related Mortgagor).

This Certificate does not purport to summarize the Pooling and Servicing Agreement, and reference is made to the Pooling and Servicing Agreement for the interests, rights, benefits, obligations and duties evidenced hereby, and the limitations thereon, and the rights, duties and immunities of the Certificate Administrator and Trustee.

As provided in the Pooling and Servicing Agreement, subject to certain restrictions on transfer set forth therein, upon surrender for registration of transfer of any Certificate, the Certificate Administrator shall execute, authenticate and deliver, in the name of the designated transferee or transferees, one or more new Certificates in authorized denominations, in like aggregate interest and of the same Class.

Prior to due presentation of this Certificate for registration of transfer, the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Certificate Registrar, and any agent of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate Registrar may treat the Person in whose name any Certificate is registered as the owner of such Certificate for the purpose of receiving distributions as provided in the Pooling and Servicing Agreement and for all other purposes whatsoever, and none of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Certificate Registrar, or any agent of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate Registrar shall be affected by any notice to the contrary.

(ix) to modify the procedures of the Pooling and Servicing Agreement relating to compliance with Rule 17g-5 of the Exchange Act; provided that such amendment shall not adversely affect in any material respects the interests of any Certificateholders (including, for the avoidance of doubt, any Holders of a VRR Interest, a Y&L Towers VRR Interest or a Standard Highline VRR Interest), as evidenced by (x) an Opinion of Counsel or (y) if any Certificate is then rated, receipt of Rating Agency Confirmation from each Rating Agency rating such Certificates; and provided, further, that the Certificate Administrator shall give notice of any such amendment to the 17g-5 Information Provider for posting to the 17g-5 Information Provider’s Website pursuant to Section 3.13(c) of the Pooling and Servicing Agreement and the Certificate Administrator shall post such notice to the Certificate Administrator’s Website;

Notwithstanding the foregoing, no such amendment (A) may change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations of any Mortgage Loan Seller under any Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller or (B) may materially and adversely affect the holders of a Companion Loan without such Companion Holder’s consent.

A-2-9

The Pooling and Servicing Agreement may also be amended from time to time by the parties thereto with the consent of the Holders of Certificates of each Class affected by such amendment (including, for the avoidance of doubt, any Holders of the VRR Interest, the Y&L Towers VRR Interest or the Standard Highline VRR Interest to the extent any such amendment would adversely affect the rights of such Certificateholders) evidencing in the aggregate not less than a majority of the aggregate Percentage Interests constituting the Class for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of the Pooling and Servicing Agreement or of modifying in any manner the rights of the Holders of Certificates of such Class; provided, however, that no such amendment shall:

(i) reduce in any manner the amount of, or delay the timing of, payments received on the Mortgage Loans or the Trust Subordinate Companion Loans that are required to be distributed on a Certificate of any class without the consent of the Holder of the Certificate or which are required to be distributed to a Companion Holder without the consent of such Companion Holder; or

(ii) reduce the aforesaid percentage of Certificates of any Class the Holders of which are required to consent to any such amendment or remove the requirement to obtain consent of any Companion Holder or Holder of Loan-Specific Certificates, in any such case, without the consent of the Holders of all Certificates of such Class then-outstanding or such Companion Holders, as applicable; or

(v) amend the Servicing Standard without the consent of 100% of the Certificateholders or receipt of Rating Agency Confirmation from each Rating Agency and confirmation of the applicable rating agencies that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings of any Serviced Companion Loan Securities, if any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement) and, if required under the related Intercreditor Agreement, the consent of the holder of any AB Subordinate Companion Loan for each Serviced AB Whole Loan.

A-2-10

Notwithstanding the foregoing, none of the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Depositor, the Master Servicer nor the Special Servicer will be required to consent to any amendment to the Pooling and Servicing Agreement without having first received an Opinion of Counsel (at the Trust’s expense) to the effect that such amendment is permitted under the Pooling and Servicing Agreement, that all conditions precedent have been satisfied and that such amendment or the exercise of any power granted to the Master Servicer, the Special Servicer, the Depositor, the Trustee, the Certificate Administrator, the Operating Advisor, the Asset Representations Reviewer or any other specified person in accordance with such amendment will not result in the imposition of a tax on any portion of the Trust Fund or any Trust REMIC, or cause any Trust REMIC to fail to qualify as a REMIC or cause the Grantor Trust to fail to qualify as a grantor trust under the relevant provisions of the Code.

The Holders of the majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates may, in that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the Certificate Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage Loans (and all property acquired through exercise of remedies in respect of any related Mortgage Loan), the Trust Subordinate Companion Loans and the Trust’s portion of each REO Property remaining in the Trust Fund, and thereby effect termination of the Trust and early retirement of the then-outstanding Certificates, only on or after the first Distribution Date on which the aggregate Stated Principal Balances of the Mortgage Loans, the Trust Subordinate Companion Loans and the portion of any REO Loans held by the Trust is less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage Loans (solely for the purposes of this calculation, if such right is being exercised after December 2027 and the 237 East Fordham Road Mortgage Loan is still an asset of the Trust, then such Mortgage Loan will be excluded from the then-aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate Companion Loans and from the aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate Companion Loans as of the Cut-off Date) as set forth in the Pooling and Servicing Agreement.

Following the date on which the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class A-S, Class X-A, Class X-B, Class X-E, Class B and Class C Regular Interests have been reduced to zero (and provided that there is only one Holder (or multiple Holders acting in unanimity) of the then-outstanding Certificates (other than the Class Z and Class R Certificates)), the Sole Certificateholder shall have the right, with the consent of the Master Servicer, to exchange all of its Certificates (other than the Class Z and Class R Certificates) together with the payment or deemed payment of the Termination Purchase Amount for all of the Mortgage Loans, the Trust Subordinate Companion Loans and each REO Property remaining in the Trust Fund pursuant to the terms of the Pooling and Servicing Agreement.

The obligations created by the Pooling and Servicing Agreement and the Trust created thereby (other than the obligation of the Certificate Administrator to make payments to Certificateholders as provided for in the Pooling and Servicing Agreement), shall terminate upon reduction of the Certificate Balances of all the Certificates to zero (including, without limitation, any such final payment resulting from a termination of the Trust due to a sale of its property) pursuant to the terms of the Pooling and Servicing Agreement. In no event, however, will the

A-2-11

Trust created by the Pooling and Servicing Agreement continue beyond the expiration of 21 years from the death of the last survivor of the descendants of Joseph P. Kennedy, the late Ambassador of the United States to the Court of St. James, living on the date hereof.

Unless the certificate of authentication hereon has been executed by the Authenticating Agent, by manual signature, this Certificate shall not be entitled to any benefit under the Pooling and Servicing Agreement or be valid for any purpose. The Certificate Registrar has executed this Certificate on behalf of the Trust as Certificate Registrar under the Pooling and Servicing Agreement and makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates, the Mortgage Loans or the Trust Subordinate Companion Loans.

This certifies that [           ] is the registered owner of a beneficial ownership interest in a Trust Fund, including the distributions to be made with respect to the Class A-3 Certificates. The Trust Fund, described more fully below, consists primarily of a pool of Mortgage Loans secured by first liens on commercial and multifamily properties and subordinate interests in two subordinate companion loans (the “Trust Subordinate Companion Loans”) held in trust by the Trustee and serviced by the Master Servicer. The Trust Fund was created, and the Mortgage Loans and the Trust Subordinate Companion Loans are to be serviced, pursuant to the Pooling and Servicing Agreement (as defined below). The Holder of this Certificate, by virtue of the acceptance hereof, assents to the terms, provisions and conditions of the Pooling and Servicing Agreement and is bound thereby. In the event that there is any conflict between any provision of this Certificate and any provision of the Pooling and Servicing Agreement, such provision of this Certificate shall be superseded to the extent of such inconsistency. Also issued under the Pooling and Servicing Agreement are the Class A-1, Class A-2, Class A-4, Class A-5, Class A-SB, Class X-A, Class X-B, Class X-E, Class A-S, Class B, Class C, Class D, Class E, Class F,

This Certificate is issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of November 1, 2017 (the “Pooling and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities Corp., as Depositor, Wells Fargo Bank, National Association, as Certificate Administrator and as Trustee, Park Bridge Lender Services LLC, as Operating Advisor and as Asset Representations Reviewer, KeyBank National Association, as Master Servicer, and CWCapital Asset Management LLC, as Special Servicer. To the extent not defined herein, capitalized terms used herein shall have the meanings assigned thereto in the Pooling and Servicing Agreement.

This Certificate represents beneficial ownership of a “regular interest” in a “real estate mortgage investment conduit,” as those terms are defined, respectively, in Sections 860G(a)(1) and 860D of the Internal Revenue Code of 1986, as amended.

The Certificate Administrator makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates, the Mortgage Loans or the Trust Subordinate Companion Loans and has executed this Certificate in its limited capacity as Certificate Administrator under the Pooling and Servicing Agreement.

Pursuant to the terms of the Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution on any Certificate), on the 4th Business Day following the determination date of each month, commencing in December 2017 (each such date, a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related Record Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this Certificate) of that portion of the aggregate amount of principal and interest then distributable, if any, allocable to the Class A-3 Certificates for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement. Holders of this Certificate may be entitled to Yield Maintenance Charges, as provided in the Pooling and Servicing Agreement.

Interest accrued on this Certificate during an Interest Accrual Period, plus the aggregate unpaid Interest Shortfall with respect to this Certificate, if any, will be payable on the related Distribution Date to the extent provided in the Pooling and Servicing Agreement. The “Interest Accrual Period” with respect to any Distribution Date and with respect to the Class A-3 Certificates is the calendar month immediately preceding the month in which such Distribution Date occurs and is assumed to consist of 30 days.

All distributions (other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons in whose names the Certificates are registered at the close of business on each Record Date, which will be the close of business on the last Business Day of the month immediately preceding the month in which such Distribution Date occurs. Distributions are required to be made (a) by wire transfer of immediately available funds to the

A-3-4

account of such Certificateholder at a bank or other entity having appropriate facilities therefor, if such Certificateholder provided the Certificate Administrator with written wiring instructions no less than five Business Days prior to the related Record Date (which wiring instructions may be in the form of a standing order applicable to all subsequent Distribution Dates), or otherwise (b) by check mailed to such Certificateholder at its address in the Certificate Register. The final distribution on each Certificate will be made in like manner, but only upon presentment and surrender of such Certificate at the offices of the Certificate Registrar or such other location specified in the notice to Certificateholders of such final distribution.

Any funds not distributed to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure of such Certificateholders to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited to the account or accounts of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been given pursuant to Section 4.01(l) of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within six months after the time specified in such notice, the Certificate Administrator shall mail a second notice to the remaining non tendering Certificateholders to surrender their Certificates for cancellation in order to receive the final distribution with respect thereto. If within one year after the second notice all such Certificates shall not have been surrendered for cancellation, the Certificate Administrator, directly or through an agent, shall take such steps to contact the remaining non tendering Certificateholders concerning the surrender of their Certificates as it shall deem appropriate and subject to escheatment and other applicable laws. The costs and expenses of holding such funds in trust and of contacting such Certificateholders following the first anniversary of the delivery of such second notice to the non-tendering Certificateholders shall be paid out of such funds. No interest shall accrue or be payable to any Certificateholder on any amount held in trust under the Pooling and Servicing Agreement by the Certificate Administrator as a result of such Certificateholder’s failure to surrender its Certificate(s) for final payment thereof in accordance with Section 4.01(l) of the Pooling and Servicing Agreement.

This Certificate is limited in right of payment to, among other things, certain collections and recoveries in respect of the Mortgage Loans, as more specifically set forth herein and in the Pooling and Servicing Agreement.

As provided in the Pooling and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject to the Pooling and Servicing Agreement (including any Qualified Substitute Mortgage Loan replacing a removed Mortgage Loan) and the Trust Subordinate Companion Loans, together with the Mortgage Files relating thereto (subject to, in the case of a Serviced Whole Loan, the interests of the related Serviced Companion Noteholder in the related Mortgage File); (ii) all scheduled or unscheduled payments on or collections in respect of the Mortgage Loans and the Trust Subordinate Companion Loans due after the Cut-off Date (or with respect to a Qualified Substitute Mortgage Loan, the Due Date in the month of substitution); (iii) any REO Property (to the extent of the Trust’s interest therein) or the Trust’s beneficial interest in the Mortgaged Property securing a Non Serviced Whole Loan acquired under the related Non-Serviced PSA; (iv) all revenues received in respect of any REO Property (to the extent of the Trust’s interest therein); (v) the Master Servicer’s, the Special Servicer’s, the Certificate Administrator’s and the Trustee’s rights under the insurance policies with respect to the Mortgage Loans and the Trust Subordinate Companion Loans required to be

A-3-5

maintained pursuant to the Pooling and Servicing Agreement and any proceeds thereof (to the extent of the Trust’s interest therein); (vi) any Assignment of Leases and any security agreements (to the extent of the Trust’s interest therein); (vii) any letters of credit, indemnities, guaranties or lease enhancement policies given as additional security for any related Mortgage Loans or Trust Subordinate Companion Loans (to the extent of the Trust’s interest therein); (viii) all assets deposited in the Loss of Value Reserve Fund and the Servicing Accounts (to the extent of the Trust’s interest therein), amounts on deposit in the Collection Account (to the extent of the Trust’s interest therein), the Lower-Tier REMIC Distribution Account, the Upper-Tier REMIC Distribution Account, the Trust Subordinate Companion Loan REMIC Distribution Accounts, the Regular Interest Distribution Account, the Excess Interest Distribution Account, the Interest Reserve Account, the Gain-on-Sale Reserve Account (to the extent of the Trust’s interest therein) and any REO Account (to the extent of the Trust’s interest therein), including any reinvestment income, as applicable; (ix) any Environmental Indemnity Agreements (to the extent of the Trust’s interest therein); (x) the rights and remedies of the Depositor under each Mortgage Loan Purchase Agreement (to the extent transferred to the Trustee); (xi) the Lower-Tier Regular Interests; (xii) the Trust Subordinate Companion Loan REMIC Regular Interests; and (xiii) the proceeds of the foregoing (other than any interest earned on deposits in the lock-box accounts, cash collateral accounts, escrow accounts and any reserve accounts, to the extent such interest belongs to the related Mortgagor).

This Certificate does not purport to summarize the Pooling and Servicing Agreement, and reference is made to the Pooling and Servicing Agreement for the interests, rights, benefits, obligations and duties evidenced hereby, and the limitations thereon, and the rights, duties and immunities of the Certificate Administrator and Trustee.

As provided in the Pooling and Servicing Agreement, subject to certain restrictions on transfer set forth therein, upon surrender for registration of transfer of any Certificate, the Certificate Administrator shall execute, authenticate and deliver, in the name of the designated transferee or transferees, one or more new Certificates in authorized denominations, in like aggregate interest and of the same Class.

Prior to due presentation of this Certificate for registration of transfer, the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Certificate Registrar, and any agent of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate Registrar may treat the Person in whose name any Certificate is registered as the owner of such Certificate for the purpose of receiving distributions as provided in the Pooling and Servicing Agreement and for all other purposes whatsoever, and none of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Certificate Registrar, or any agent of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate Registrar shall be affected by any notice to the contrary.

The Pooling and Servicing Agreement may be amended from time to time by the Depositor, the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Certificate Administrator and the Trustee, without the consent of any of the Certificateholders or the Companion Holders:

A-3-6

(i) to correct any defect or ambiguity in the Pooling and Servicing Agreement;

(iii) to change the timing and/or nature of deposits in the Collection Account, the Distribution Accounts or any REO Account; provided that (a) the P&I Advance Date shall in no event be later than the Business Day prior to the related Distribution Date and (b) such change shall not adversely affect in any material respect the interests of any Certificateholder (including, for the avoidance of doubt, any Holder of a VRR Interest, a Y&L Towers VRR Interest or a Standard Highline VRR Interest), as evidenced in writing by an Opinion of Counsel at the expense of the party requesting such amendment or as evidenced by a Rating Agency Confirmation from each Rating Agency with respect to such amendment;

(iv) to modify, eliminate or add to any provisions of the Pooling and Servicing Agreement to such extent as shall be necessary to maintain the qualification of any Trust REMIC as a REMIC or the Grantor Trust as a grantor trust under the relevant provisions of the Code at all times that any Certificate is outstanding, or to avoid or minimize the risk of imposition of any tax on the Trust or any Trust REMIC or the Grantor Trust; provided that the Trustee and the Certificate Administrator have received an Opinion of Counsel (at the expense of the party requesting such amendment) to the effect that (a) such action is necessary or desirable to maintain such qualification or to avoid or minimize the risk of the imposition of any such tax and (b) such action will not adversely affect in any material respect the interests of any Certificateholder (including, for the avoidance of doubt, any Holder of a VRR Interest, a Y&L Towers VRR Interest or a Standard Highline VRR Interest), or Companion Holder;

(v) to modify, eliminate or add to the provisions of Section 5.03(o) of the Pooling and Servicing Agreement or any other provision of the Pooling and Servicing Agreement restricting transfer of the Class R Certificates; provided the Depositor has determined that such change shall not, as evidenced by an Opinion of Counsel, cause the Trust, any Trust REMIC or any of the Certificateholders (other than the Transferor) to be subject to a federal tax caused by a Transfer to a Person that is a Disqualified Organization or a Non-U.S. Tax Person;

A-3-7

(vi) to revise or add any other provisions with respect to matters or questions arising under the Pooling and Servicing Agreement or any other change; provided that the required action shall not adversely affect in any material respect the interests of any Certificateholder (including, for the avoidance of doubt, any Holder of a VRR Interest, a Y&L Towers VRR Interest or a Standard Highline VRR Interest) or any holder of a Serviced Pari Passu Companion Loan not consenting to such revision or addition, as evidenced in writing by an Opinion of Counsel, at the expense of the party requesting such amendment or as evidenced by a Rating Agency Confirmation from each of the Rating Agencies with respect to such amendment or supplement and confirmation of the applicable rating agencies that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings of any class of Serviced Companion Loan Securities, if any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement);

(viii) to modify the provisions of Sections 3.05 and 3.17 of the Pooling and Servicing Agreement (with respect to reimbursement of Nonrecoverable Advances and Workout-Delayed Reimbursement Amounts) if (a) the Depositor, the Master Servicer, the Trustee and, for so long as a Control Termination Event has not occurred and is not continuing and, with respect to any Mortgage Loans other than any Excluded Loan, as to the Directing Holder or, in the case of the Directing Certificateholder, the Holder of a majority of the Controlling Class, the Directing Holder, determine that the commercial mortgage backed securities industry standard for such provisions has changed, in order to conform to such industry standard, (b) such modification does not adversely affect the status of any Trust REMIC as a REMIC or the status of the Grantor Trust

A-3-8

as a grantor trust under the relevant provisions of the Code, as evidenced by an Opinion of Counsel and (c) each Rating Agency has delivered a Rating Agency Confirmation and, with regard to any class of Serviced Companion Loan Securities, the applicable rating agencies have delivered a confirmation that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement);

(ix) to modify the procedures of the Pooling and Servicing Agreement relating to compliance with Rule 17g-5 of the Exchange Act; provided that such amendment shall not adversely affect in any material respects the interests of any Certificateholders (including, for the avoidance of doubt, any Holders of a VRR Interest, a Y&L Towers VRR Interest or a Standard Highline VRR Interest), as evidenced by (x) an Opinion of Counsel or (y) if any Certificate is then rated, receipt of Rating Agency Confirmation from each Rating Agency rating such Certificates; and provided, further, that the Certificate Administrator shall give notice of any such amendment to the 17g-5 Information Provider for posting to the 17g-5 Information Provider’s Website pursuant to Section 3.13(c) of the Pooling and Servicing Agreement and the Certificate Administrator shall post such notice to the Certificate Administrator’s Website;

(x) to modify, eliminate or add to any provisions of the Pooling and Servicing Agreement to such extent as shall be necessary to comply with the requirements for use of Form SF-3 in registered offerings to the extent provided in CFR 239.45(b)(1)(ii), (iii) or (iv); or

(xi) to modify, eliminate or add to any of its provisions in the event the Credit Risk Retention Rules or any other regulations applicable to the risk retention requirements for this securitization transaction are amended or repealed, to the extent required to comply with any such amendment or to modify or eliminate the provision related to the risk retention requirements in the event of such repeal.

Notwithstanding the foregoing, no such amendment (A) may change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations of any Mortgage Loan Seller under any Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller or (B) may materially and adversely affect the holders of a Companion Loan without such Companion Holder’s consent. 

The Pooling and Servicing Agreement may also be amended from time to time by the parties thereto with the consent of the Holders of Certificates of each Class affected by such amendment (including, for the avoidance of doubt, any Holders of the VRR Interest, the Y&L Towers VRR

A-3-9

Interest or the Standard Highline VRR Interest to the extent any such amendment would adversely affect the rights of such Certificateholders) evidencing in the aggregate not less than a majority of the aggregate Percentage Interests constituting the Class for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of the Pooling and Servicing Agreement or of modifying in any manner the rights of the Holders of Certificates of such Class; provided, however, that no such amendment shall:

(i) reduce in any manner the amount of, or delay the timing of, payments received on the Mortgage Loans or the Trust Subordinate Companion Loans that are required to be distributed on a Certificate of any class without the consent of the Holder of the Certificate or which are required to be distributed to a Companion Holder without the consent of such Companion Holder; or

(ii) reduce the aforesaid percentage of Certificates of any Class the Holders of which are required to consent to any such amendment or remove the requirement to obtain consent of any Companion Holder or Holder of Loan-Specific Certificates, in any such case, without the consent of the Holders of all Certificates of such Class then-outstanding or such Companion Holders, as applicable; or

(iii) adversely affect the Voting Rights of any Class of Certificates without the consent of the Holders of all Certificates of such Class then outstanding; or

(iv) change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations of any Mortgage Loan Seller under such Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller; or

(v) amend the Servicing Standard without the consent of 100% of the Certificateholders or receipt of Rating Agency Confirmation from each Rating Agency and confirmation of the applicable rating agencies that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings of any Serviced Companion Loan Securities, if any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement) and, if required under the related Intercreditor Agreement, the consent of the holder of any AB Subordinate Companion Loan for each Serviced AB Whole Loan.

Notwithstanding the foregoing, none of the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Depositor, the Master Servicer nor the Special Servicer will be required to consent to any amendment to the Pooling and Servicing Agreement without having first received an Opinion of Counsel (at the Trust’s expense) to the

A-3-10

effect that such amendment is permitted under the Pooling and Servicing Agreement, that all conditions precedent have been satisfied and that such amendment or the exercise of any power granted to the Master Servicer, the Special Servicer, the Depositor, the Trustee, the Certificate Administrator, the Operating Advisor, the Asset Representations Reviewer or any other specified person in accordance with such amendment will not result in the imposition of a tax on any portion of the Trust Fund or any Trust REMIC, or cause any Trust REMIC to fail to qualify as a REMIC or cause the Grantor Trust to fail to qualify as a grantor trust under the relevant provisions of the Code.

The Holders of the majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates may, in that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the Certificate Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage Loans (and all property acquired through exercise of remedies in respect of any related Mortgage Loan), the Trust Subordinate Companion Loans and the Trust’s portion of each REO Property remaining in the Trust Fund, and thereby effect termination of the Trust and early retirement of the then-outstanding Certificates, only on or after the first Distribution Date on which the aggregate Stated Principal Balances of the Mortgage Loans, the Trust Subordinate Companion Loans and the portion of any REO Loans held by the Trust is less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage Loans (solely for the purposes of this calculation, if such right is being exercised after December 2027 and the 237 East Fordham Road Mortgage Loan is still an asset of the Trust, then such Mortgage Loan will be excluded from the then-aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate Companion Loans and from the aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate Companion Loans as of the Cut-off Date) as set forth in the Pooling and Servicing Agreement.

Following the date on which the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class A-S, Class X-A, Class X-B, Class X-E, Class B and Class C Regular Interests have been reduced to zero (and provided that there is only one Holder (or multiple Holders acting in unanimity) of the then-outstanding Certificates (other than the Class Z and Class R Certificates)), the Sole Certificateholder shall have the right, with the consent of the Master Servicer, to exchange all of its Certificates (other than the Class Z and Class R Certificates) together with the payment or deemed payment of the Termination Purchase Amount for all of the Mortgage Loans, the Trust Subordinate Companion Loans and each REO Property remaining in the Trust Fund pursuant to the terms of the Pooling and Servicing Agreement.

The obligations created by the Pooling and Servicing Agreement and the Trust created thereby (other than the obligation of the Certificate Administrator to make payments to Certificateholders as provided for in the Pooling and Servicing Agreement), shall terminate upon reduction of the Certificate Balances of all the Certificates to zero (including, without limitation, any such final payment resulting from a termination of the Trust due to a sale of its property) pursuant to the terms of the Pooling and Servicing Agreement. In no event, however, will the Trust created by the Pooling and Servicing Agreement continue beyond the expiration of 21 years from the death of the last survivor of the descendants of Joseph P. Kennedy, the late Ambassador of the United States to the Court of St. James, living on the date hereof.

This certifies that [           ] is the registered owner of a beneficial ownership interest in a Trust Fund, including the distributions to be made with respect to the Class A-4 Certificates. The Trust Fund, described more fully below, consists primarily of a pool of Mortgage Loans secured by first liens on commercial and multifamily properties and subordinate interests in two subordinate companion loans (the “Trust Subordinate Companion Loans”) held in trust by the Trustee and serviced by the Master Servicer. The Trust Fund was created, and the Mortgage Loans and the Trust Subordinate Companion Loans are to be serviced, pursuant to the Pooling and Servicing Agreement (as defined below). The Holder of this Certificate, by virtue of the acceptance hereof, assents to the terms, provisions and conditions of the Pooling and Servicing Agreement and is bound thereby. In the event that there is any conflict between any provision of this Certificate and any provision of the Pooling and Servicing Agreement, such provision of this Certificate shall be superseded to the extent of such inconsistency. Also issued under the Pooling and Servicing Agreement are the Class A-1, Class A-2, Class A-3, Class A-5, Class A-SB, Class X-A, Class X-B, Class X-E, Class A-S, Class B, Class C, Class D, Class E, Class F,

This Certificate is issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of November 1, 2017 (the “Pooling and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities Corp., as Depositor, Wells Fargo Bank, National Association, as Certificate Administrator and as Trustee, Park Bridge Lender Services LLC, as Operating Advisor and as Asset Representations Reviewer, KeyBank National Association, as Master Servicer, and CWCapital Asset Management LLC, as Special Servicer. To the extent not defined herein, capitalized terms used herein shall have the meanings assigned thereto in the Pooling and Servicing Agreement.

This Certificate represents beneficial ownership of a “regular interest” in a “real estate mortgage investment conduit,” as those terms are defined, respectively, in Sections 860G(a)(1) and 860D of the Internal Revenue Code of 1986, as amended.

The Certificate Administrator makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates, the Mortgage Loans or the Trust Subordinate Companion Loans and has executed this Certificate in its limited capacity as Certificate Administrator under the Pooling and Servicing Agreement.

Pursuant to the terms of the Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution on any Certificate), on the 4th Business Day following the determination date of each month, commencing in December 2017 (each such date, a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related Record Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this Certificate) of that portion of the aggregate amount of principal and interest then distributable, if any, allocable to the Class A-4 Certificates for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement. Holders of this Certificate may be entitled to Yield Maintenance Charges, as provided in the Pooling and Servicing Agreement.

Interest accrued on this Certificate during an Interest Accrual Period, plus the aggregate unpaid Interest Shortfall with respect to this Certificate, if any, will be payable on the related Distribution Date to the extent provided in the Pooling and Servicing Agreement. The “Interest Accrual Period” with respect to any Distribution Date and with respect to the Class A-4 Certificates is the calendar month immediately preceding the month in which such Distribution Date occurs and is assumed to consist of 30 days.

All distributions (other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons in whose names the Certificates are registered at the close of business on each Record Date, which will be the close of business on the last Business Day of the month immediately preceding the month in which such Distribution Date occurs. Distributions are required to be made (a) by wire transfer of immediately available funds to the

A-4-4

account of such Certificateholder at a bank or other entity having appropriate facilities therefor, if such Certificateholder provided the Certificate Administrator with written wiring instructions no less than five Business Days prior to the related Record Date (which wiring instructions may be in the form of a standing order applicable to all subsequent Distribution Dates), or otherwise (b) by check mailed to such Certificateholder at its address in the Certificate Register. The final distribution on each Certificate will be made in like manner, but only upon presentment and surrender of such Certificate at the offices of the Certificate Registrar or such other location specified in the notice to Certificateholders of such final distribution.

Any funds not distributed to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure of such Certificateholders to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited to the account or accounts of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been given pursuant to Section 4.01(l) of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within six months after the time specified in such notice, the Certificate Administrator shall mail a second notice to the remaining non tendering Certificateholders to surrender their Certificates for cancellation in order to receive the final distribution with respect thereto. If within one year after the second notice all such Certificates shall not have been surrendered for cancellation, the Certificate Administrator, directly or through an agent, shall take such steps to contact the remaining non tendering Certificateholders concerning the surrender of their Certificates as it shall deem appropriate and subject to escheatment and other applicable laws. The costs and expenses of holding such funds in trust and of contacting such Certificateholders following the first anniversary of the delivery of such second notice to the non-tendering Certificateholders shall be paid out of such funds. No interest shall accrue or be payable to any Certificateholder on any amount held in trust under the Pooling and Servicing Agreement by the Certificate Administrator as a result of such Certificateholder’s failure to surrender its Certificate(s) for final payment thereof in accordance with Section 4.01(l) of the Pooling and Servicing Agreement.

This Certificate is limited in right of payment to, among other things, certain collections and recoveries in respect of the Mortgage Loans, as more specifically set forth herein and in the Pooling and Servicing Agreement.

As provided in the Pooling and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject to the Pooling and Servicing Agreement (including any Qualified Substitute Mortgage Loan replacing a removed Mortgage Loan) and the Trust Subordinate Companion Loans, together with the Mortgage Files relating thereto (subject to, in the case of a Serviced Whole Loan, the interests of the related Serviced Companion Noteholder in the related Mortgage File); (ii) all scheduled or unscheduled payments on or collections in respect of the Mortgage Loans and the Trust Subordinate Companion Loans due after the Cut-off Date (or with respect to a Qualified Substitute Mortgage Loan, the Due Date in the month of substitution); (iii) any REO Property (to the extent of the Trust’s interest therein) or the Trust’s beneficial interest in the Mortgaged Property securing a Non Serviced Whole Loan acquired under the related Non-Serviced PSA; (iv) all revenues received in respect of any REO Property (to the extent of the Trust’s interest therein); (v) the Master Servicer’s, the Special Servicer’s, the Certificate Administrator’s and the Trustee’s rights under the insurance policies with respect to the Mortgage Loans and the Trust Subordinate Companion Loans required to be

A-4-5

maintained pursuant to the Pooling and Servicing Agreement and any proceeds thereof (to the extent of the Trust’s interest therein); (vi) any Assignment of Leases and any security agreements (to the extent of the Trust’s interest therein); (vii) any letters of credit, indemnities, guaranties or lease enhancement policies given as additional security for any related Mortgage Loans or Trust Subordinate Companion Loans (to the extent of the Trust’s interest therein); (viii) all assets deposited in the Loss of Value Reserve Fund and the Servicing Accounts (to the extent of the Trust’s interest therein), amounts on deposit in the Collection Account (to the extent of the Trust’s interest therein), the Lower-Tier REMIC Distribution Account, the Upper-Tier REMIC Distribution Account, the Trust Subordinate Companion Loan REMIC Distribution Accounts, the Regular Interest Distribution Account, the Excess Interest Distribution Account, the Interest Reserve Account, the Gain-on-Sale Reserve Account (to the extent of the Trust’s interest therein) and any REO Account (to the extent of the Trust’s interest therein), including any reinvestment income, as applicable; (ix) any Environmental Indemnity Agreements (to the extent of the Trust’s interest therein); (x) the rights and remedies of the Depositor under each Mortgage Loan Purchase Agreement (to the extent transferred to the Trustee); (xi) the Lower-Tier Regular Interests; (xii) the Trust Subordinate Companion Loan REMIC Regular Interests; and (xiii) the proceeds of the foregoing (other than any interest earned on deposits in the lock-box accounts, cash collateral accounts, escrow accounts and any reserve accounts, to the extent such interest belongs to the related Mortgagor).

This Certificate does not purport to summarize the Pooling and Servicing Agreement, and reference is made to the Pooling and Servicing Agreement for the interests, rights, benefits, obligations and duties evidenced hereby, and the limitations thereon, and the rights, duties and immunities of the Certificate Administrator and Trustee.

As provided in the Pooling and Servicing Agreement, subject to certain restrictions on transfer set forth therein, upon surrender for registration of transfer of any Certificate, the Certificate Administrator shall execute, authenticate and deliver, in the name of the designated transferee or transferees, one or more new Certificates in authorized denominations, in like aggregate interest and of the same Class.

Prior to due presentation of this Certificate for registration of transfer, the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Certificate Registrar, and any agent of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate Registrar may treat the Person in whose name any Certificate is registered as the owner of such Certificate for the purpose of receiving distributions as provided in the Pooling and Servicing Agreement and for all other purposes whatsoever, and none of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Certificate Registrar, or any agent of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate Registrar shall be affected by any notice to the contrary.

(iii) to change the timing and/or nature of deposits in the Collection Account, the Distribution Accounts or any REO Account; provided that (a) the P&I Advance Date shall in no event be later than the Business Day prior to the related Distribution Date and (b) such change shall not adversely affect in any material respect the interests of any Certificateholder (including, for the avoidance of doubt, any Holder of a VRR Interest, a Y&L Towers VRR Interest or a Standard Highline VRR Interest), as evidenced in writing by an Opinion of Counsel at the expense of the party requesting such amendment or as evidenced by a Rating Agency Confirmation from each Rating Agency with respect to such amendment;

(iv) to modify, eliminate or add to any provisions of the Pooling and Servicing Agreement to such extent as shall be necessary to maintain the qualification of any Trust REMIC as a REMIC or the Grantor Trust as a grantor trust under the relevant provisions of the Code at all times that any Certificate is outstanding, or to avoid or minimize the risk of imposition of any tax on the Trust or any Trust REMIC or the Grantor Trust; provided that the Trustee and the Certificate Administrator have received an Opinion of Counsel (at the expense of the party requesting such amendment) to the effect that (a) such action is necessary or desirable to maintain such qualification or to avoid or minimize the risk of the imposition of any such tax and (b) such action will not adversely affect in any material respect the interests of any Certificateholder (including, for the avoidance of doubt, any Holder of a VRR Interest, a Y&L Towers VRR Interest or a Standard Highline VRR Interest), or Companion Holder;

(v) to modify, eliminate or add to the provisions of Section 5.03(o) of the Pooling and Servicing Agreement or any other provision of the Pooling and Servicing Agreement restricting transfer of the Class R Certificates; provided the Depositor has determined that such change shall not, as evidenced by an Opinion of Counsel, cause the Trust, any Trust REMIC or

A-4-7

any of the Certificateholders (other than the Transferor) to be subject to a federal tax caused by a Transfer to a Person that is a Disqualified Organization or a Non-U.S. Tax Person;

(vi) to revise or add any other provisions with respect to matters or questions arising under the Pooling and Servicing Agreement or any other change; provided that the required action shall not adversely affect in any material respect the interests of any Certificateholder (including, for the avoidance of doubt, any Holder of a VRR Interest, a Y&L Towers VRR Interest or a Standard Highline VRR Interest) or any holder of a Serviced Pari Passu Companion Loan not consenting to such revision or addition, as evidenced in writing by an Opinion of Counsel, at the expense of the party requesting such amendment or as evidenced by a Rating Agency Confirmation from each of the Rating Agencies with respect to such amendment or supplement and confirmation of the applicable rating agencies that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings of any class of Serviced Companion Loan Securities, if any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement);

(viii) to modify the provisions of Sections 3.05 and 3.17 of the Pooling and Servicing Agreement (with respect to reimbursement of Nonrecoverable Advances and Workout-Delayed Reimbursement Amounts) if (a) the Depositor, the Master Servicer, the Trustee and, for so long as a Control Termination Event has not occurred and is not continuing and, with respect to any Mortgage Loans other than any Excluded Loan, as to the Directing Holder or, in the case of the Directing Certificateholder, the Holder of a majority of the Controlling Class, the Directing Holder,

A-4-8

(ix) to modify the procedures of the Pooling and Servicing Agreement relating to compliance with Rule 17g-5 of the Exchange Act; provided that such amendment shall not adversely affect in any material respects the interests of any Certificateholders (including, for the avoidance of doubt, any Holders of a VRR Interest, a Y&L Towers VRR Interest or a Standard Highline VRR Interest), as evidenced by (x) an Opinion of Counsel or (y) if any Certificate is then rated, receipt of Rating Agency Confirmation from each Rating Agency rating such Certificates; and provided, further, that the Certificate Administrator shall give notice of any such amendment to the 17g-5 Information Provider for posting to the 17g-5 Information Provider’s Website pursuant to Section 3.13(c) of the Pooling and Servicing Agreement and the Certificate Administrator shall post such notice to the Certificate Administrator’s Website;

Notwithstanding the foregoing, no such amendment (A) may change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations of any Mortgage Loan Seller under any Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller or (B) may materially and adversely affect the holders of a Companion Loan without such Companion Holder’s consent. 

A-4-9

The Pooling and Servicing Agreement may also be amended from time to time by the parties thereto with the consent of the Holders of Certificates of each Class affected by such amendment (including, for the avoidance of doubt, any Holders of the VRR Interest, the Y&L Towers VRR Interest or the Standard Highline VRR Interest to the extent any such amendment would adversely affect the rights of such Certificateholders) evidencing in the aggregate not less than a majority of the aggregate Percentage Interests constituting the Class for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of the Pooling and Servicing Agreement or of modifying in any manner the rights of the Holders of Certificates of such Class; provided, however, that no such amendment shall:

(i) reduce in any manner the amount of, or delay the timing of, payments received on the Mortgage Loans or the Trust Subordinate Companion Loans that are required to be distributed on a Certificate of any class without the consent of the Holder of the Certificate or which are required to be distributed to a Companion Holder without the consent of such Companion Holder; or

(ii) reduce the aforesaid percentage of Certificates of any Class the Holders of which are required to consent to any such amendment or remove the requirement to obtain consent of any Companion Holder or Holder of Loan-Specific Certificates, in any such case, without the consent of the Holders of all Certificates of such Class then-outstanding or such Companion Holders, as applicable; or

A-4-10

Notwithstanding the foregoing, none of the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Depositor, the Master Servicer nor the Special Servicer will be required to consent to any amendment to the Pooling and Servicing Agreement without having first received an Opinion of Counsel (at the Trust’s expense) to the effect that such amendment is permitted under the Pooling and Servicing Agreement, that all conditions precedent have been satisfied and that such amendment or the exercise of any power granted to the Master Servicer, the Special Servicer, the Depositor, the Trustee, the Certificate Administrator, the Operating Advisor, the Asset Representations Reviewer or any other specified person in accordance with such amendment will not result in the imposition of a tax on any portion of the Trust Fund or any Trust REMIC, or cause any Trust REMIC to fail to qualify as a REMIC or cause the Grantor Trust to fail to qualify as a grantor trust under the relevant provisions of the Code.

The Holders of the majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates may, in that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the Certificate Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage Loans (and all property acquired through exercise of remedies in respect of any related Mortgage Loan), the Trust Subordinate Companion Loans and the Trust’s portion of each REO Property remaining in the Trust Fund, and thereby effect termination of the Trust and early retirement of the then-outstanding Certificates, only on or after the first Distribution Date on which the aggregate Stated Principal Balances of the Mortgage Loans, the Trust Subordinate Companion Loans and the portion of any REO Loans held by the Trust is less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage Loans (solely for the purposes of this calculation, if such right is being exercised after December 2027 and the 237 East Fordham Road Mortgage Loan is still an asset of the Trust, then such Mortgage Loan will be excluded from the then-aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate Companion Loans and from the aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate Companion Loans as of the Cut-off Date) as set forth in the Pooling and Servicing Agreement.

Following the date on which the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class A-S, Class X-A, Class X-B, Class X-E, Class B and Class C Regular Interests have been reduced to zero (and provided that there is only one Holder (or multiple Holders acting in unanimity) of the then-outstanding Certificates (other than the Class Z and Class R Certificates)), the Sole Certificateholder shall have the right, with the consent of the Master Servicer, to exchange all of its Certificates (other than the Class Z and Class R Certificates) together with the payment or deemed payment of the Termination Purchase Amount for all of the Mortgage Loans, the Trust Subordinate Companion Loans and each REO Property remaining in the Trust Fund pursuant to the terms of the Pooling and Servicing Agreement.

The obligations created by the Pooling and Servicing Agreement and the Trust created thereby (other than the obligation of the Certificate Administrator to make payments to Certificateholders as provided for in the Pooling and Servicing Agreement), shall terminate upon reduction of the Certificate Balances of all the Certificates to zero (including, without limitation, any such final payment resulting from a termination of the Trust due to a sale of its property) pursuant to the terms of the Pooling and Servicing Agreement. In no event, however, will the

A-4-11

Trust created by the Pooling and Servicing Agreement continue beyond the expiration of 21 years from the death of the last survivor of the descendants of Joseph P. Kennedy, the late Ambassador of the United States to the Court of St. James, living on the date hereof.

Unless the certificate of authentication hereon has been executed by the Authenticating Agent, by manual signature, this Certificate shall not be entitled to any benefit under the Pooling and Servicing Agreement or be valid for any purpose. The Certificate Registrar has executed this Certificate on behalf of the Trust as Certificate Registrar under the Pooling and Servicing Agreement and makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates, the Mortgage Loans or the Trust Subordinate Companion Loans.

This certifies that [           ] is the registered owner of a beneficial ownership interest in a Trust Fund, including the distributions to be made with respect to the Class A-5 Certificates. The Trust Fund, described more fully below, consists primarily of a pool of Mortgage Loans secured by first liens on commercial and multifamily properties and subordinate interests in two subordinate companion loans (the “Trust Subordinate Companion Loans”) held in trust by the Trustee and serviced by the Master Servicer. The Trust Fund was created, and the Mortgage Loans and the Trust Subordinate Companion Loans are to be serviced, pursuant to the Pooling and Servicing Agreement (as defined below). The Holder of this Certificate, by virtue of the acceptance hereof, assents to the terms, provisions and conditions of the Pooling and Servicing Agreement and is bound thereby. In the event that there is any conflict between any provision of this Certificate and any provision of the Pooling and Servicing Agreement, such provision of this Certificate shall be superseded to the extent of such inconsistency. Also issued under the Pooling and Servicing Agreement are the Class A-1, Class A-2, Class A-3, Class A-4, Class A-

This Certificate is issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of November 1, 2017 (the “Pooling and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities Corp., as Depositor, Wells Fargo Bank, National Association, as Certificate Administrator and as Trustee, Park Bridge Lender Services LLC, as Operating Advisor and as Asset Representations Reviewer, KeyBank National Association, as Master Servicer, and CWCapital Asset Management LLC, as Special Servicer.

The Certificate Administrator makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates, the Mortgage Loans or the Trust Subordinate Companion Loans and has executed this Certificate in its limited capacity as Certificate Administrator under the Pooling and Servicing Agreement.

Pursuant to the terms of the Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution on any Certificate), on the 4th Business Day following the determination date of each month, commencing in December 2017 (each such date, a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related Record Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this Certificate) of that portion of the aggregate amount of principal and interest then distributable, if any, allocable to the Class A-5 Certificates for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement. Holders of this Certificate may be entitled to Yield Maintenance Charges, as provided in the Pooling and Servicing Agreement.

Interest accrued on this Certificate during an Interest Accrual Period, plus the aggregate unpaid Interest Shortfall with respect to this Certificate, if any, will be payable on the related Distribution Date to the extent provided in the Pooling and Servicing Agreement. The “Interest Accrual Period” with respect to any Distribution Date and with respect to the Class A-5 Certificates is the calendar month immediately preceding the month in which such Distribution Date occurs and is assumed to consist of 30 days.

All distributions (other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons in whose names the Certificates are registered at the close of business on each Record Date, which will be the close of business on the last Business Day of the month immediately preceding the month in which such Distribution Date occurs.

 A-5-4

Distributions are required to be made (a) by wire transfer of immediately available funds to the account of such Certificateholder at a bank or other entity having appropriate facilities therefor, if such Certificateholder provided the Certificate Administrator with written wiring instructions no less than five Business Days prior to the related Record Date (which wiring instructions may be in the form of a standing order applicable to all subsequent Distribution Dates), or otherwise (b) by check mailed to such Certificateholder at its address in the Certificate Register. The final distribution on each Certificate will be made in like manner, but only upon presentment and surrender of such Certificate at the offices of the Certificate Registrar or such other location specified in the notice to Certificateholders of such final distribution.

Any funds not distributed to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure of such Certificateholders to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited to the account or accounts of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been given pursuant to Section 4.01(l) of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within six months after the time specified in such notice, the Certificate Administrator shall mail a second notice to the remaining non tendering Certificateholders to surrender their Certificates for cancellation in order to receive the final distribution with respect thereto. If within one year after the second notice all such Certificates shall not have been surrendered for cancellation, the Certificate Administrator, directly or through an agent, shall take such steps to contact the remaining non tendering Certificateholders concerning the surrender of their Certificates as it shall deem appropriate and subject to escheatment and other applicable laws. The costs and expenses of holding such funds in trust and of contacting such Certificateholders following the first anniversary of the delivery of such second notice to the non-tendering Certificateholders shall be paid out of such funds. No interest shall accrue or be payable to any Certificateholder on any amount held in trust under the Pooling and Servicing Agreement by the Certificate Administrator as a result of such Certificateholder’s failure to surrender its Certificate(s) for final payment thereof in accordance with Section 4.01(l) of the Pooling and Servicing Agreement.

This Certificate is limited in right of payment to, among other things, certain collections and recoveries in respect of the Mortgage Loans, as more specifically set forth herein and in the Pooling and Servicing Agreement.

As provided in the Pooling and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject to the Pooling and Servicing Agreement (including any Qualified Substitute Mortgage Loan replacing a removed Mortgage Loan) and the Trust Subordinate Companion Loans, together with the Mortgage Files relating thereto (subject to, in the case of a Serviced Whole Loan, the interests of the related Serviced Companion Noteholder in the related Mortgage File); (ii) all scheduled or unscheduled payments on or collections in respect of the Mortgage Loans and the Trust Subordinate Companion Loans due after the Cut-off Date (or with respect to a Qualified Substitute Mortgage Loan, the Due Date in the month of substitution); (iii) any REO Property (to the extent of the Trust’s interest therein) or the Trust’s beneficial interest in the Mortgaged Property securing a Non Serviced Whole Loan acquired under the related Non-Serviced PSA; (iv) all revenues received in respect of any REO Property (to the extent of the Trust’s interest therein); (v) the Master Servicer’s, the Special Servicer’s, the Certificate Administrator’s and the Trustee’s rights under the insurance policies

This Certificate does not purport to summarize the Pooling and Servicing Agreement, and reference is made to the Pooling and Servicing Agreement for the interests, rights, benefits, obligations and duties evidenced hereby, and the limitations thereon, and the rights, duties and immunities of the Certificate Administrator and Trustee.

As provided in the Pooling and Servicing Agreement, subject to certain restrictions on transfer set forth therein, upon surrender for registration of transfer of any Certificate, the Certificate Administrator shall execute, authenticate and deliver, in the name of the designated transferee or transferees, one or more new Certificates in authorized denominations, in like aggregate interest and of the same Class.

Notwithstanding the foregoing, no such amendment (A) may change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations of any Mortgage Loan Seller under any Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller or (B) may materially and adversely affect the holders of a Companion Loan without such Companion Holder’s consent.

 A-5-10

Notwithstanding the foregoing, none of the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Depositor, the Master Servicer nor the Special Servicer will be required to consent to any amendment to the Pooling and Servicing Agreement without having first received an Opinion of Counsel (at the Trust’s expense) to the effect that such amendment is permitted under the Pooling and Servicing Agreement, that all conditions precedent have been satisfied and that such amendment or the exercise of any power granted to the Master Servicer, the Special Servicer, the Depositor, the Trustee, the Certificate Administrator, the Operating Advisor, the Asset Representations Reviewer or any other specified person in accordance with such amendment will not result in the imposition of a tax on any portion of the Trust Fund or any Trust REMIC, or cause any Trust REMIC to fail to qualify as a REMIC or cause the Grantor Trust to fail to qualify as a grantor trust under the relevant provisions of the Code.

The Holders of the majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates may, in that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the Certificate Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage Loans (and all property acquired through exercise of remedies in respect of any related Mortgage Loan), the Trust Subordinate Companion Loans and the Trust’s portion of each REO Property remaining in the Trust Fund, and thereby effect termination of the Trust and early retirement of the then-outstanding Certificates, only on or after the first Distribution Date on which the aggregate Stated Principal Balances of the Mortgage Loans, the Trust Subordinate Companion Loans and the portion of any REO Loans held by the Trust is less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage Loans (solely for the purposes of this calculation, if such right is being exercised after December 2027 and the 237 East Fordham Road Mortgage Loan is still an asset of the Trust, then such Mortgage Loan will be excluded from the then-aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate Companion Loans and from the aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate Companion Loans as of the Cut-off Date) as set forth in the Pooling and Servicing Agreement.

Following the date on which the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class A-S, Class X-A, Class X-B, Class X-E, Class B and Class C Regular Interests have been reduced to zero (and provided that there is only one Holder (or multiple Holders acting in unanimity) of the then-outstanding Certificates (other than the Class Z and Class R Certificates)), the Sole Certificateholder shall have the right, with the consent of the Master Servicer, to exchange all of its Certificates (other than the Class Z and Class R Certificates) together with the payment or deemed payment of the Termination Purchase Amount for all of the Mortgage Loans, the Trust Subordinate Companion Loans and each REO Property remaining in the Trust Fund pursuant to the terms of the Pooling and Servicing Agreement.

The obligations created by the Pooling and Servicing Agreement and the Trust created thereby (other than the obligation of the Certificate Administrator to make payments to Certificateholders as provided for in the Pooling and Servicing Agreement), shall terminate upon reduction of the Certificate Balances of all the Certificates to zero (including, without limitation, any such final payment resulting from a termination of the Trust due to a sale of its property) pursuant to the terms of the Pooling and Servicing Agreement. In no event, however, will the

 A-5-11

Trust created by the Pooling and Servicing Agreement continue beyond the expiration of 21 years from the death of the last survivor of the descendants of Joseph P. Kennedy, the late Ambassador of the United States to the Court of St. James, living on the date hereof.

Unless the certificate of authentication hereon has been executed by the Authenticating Agent, by manual signature, this Certificate shall not be entitled to any benefit under the Pooling and Servicing Agreement or be valid for any purpose. The Certificate Registrar has executed this Certificate on behalf of the Trust as Certificate Registrar under the Pooling and Servicing Agreement and makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates, the Mortgage Loans or the Trust Subordinate Companion Loans.

This certifies that [           ] is the registered owner of a beneficial ownership interest in a Trust Fund, including the distributions to be made with respect to the Class A-SB Certificates. The Trust Fund, described more fully below, consists primarily of a pool of Mortgage Loans secured by first liens on commercial and multifamily properties and subordinate interests in two subordinate companion loans (the “Trust Subordinate Companion Loans”) held in trust by the Trustee and serviced by the Master Servicer. The Trust Fund was created, and the Mortgage Loans and the Trust Subordinate Companion Loans are to be serviced, pursuant to the Pooling and Servicing Agreement (as defined below). The Holder of this Certificate, by virtue of the acceptance hereof, assents to the terms, provisions and conditions of the Pooling and Servicing Agreement and is bound thereby. In the event that there is any conflict between any provision of this Certificate and any provision of the Pooling and Servicing Agreement, such provision of this Certificate shall be superseded to the extent of such inconsistency. Also issued under the Pooling and Servicing Agreement are the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5,

 A-6-2

Class X-A, Class X-B, Class X-E, Class A-S, Class B, Class C, Class D, Class E, Class F, Class NR, Class V1-A, Class V1-B, Class V1-D, Class V1-E, Class V1-F, Class V1-Z, Class V2-A, Class V2-Z, Class UES-A, Class UES-B, Class UES-C, Class UES-D, Class UES-X, Class STN-A, Class STN-B, Class STN-X, Class STN-C, Class V1-UESA, Class V1-UESD, Class V2-UES, Class V1-STNA, Class V1-STNC, Class V2-STN, Class R and Class Z Certificates (together with the Class A-SB Certificates, the “Certificates”; the Holders of Certificates are collectively referred to herein as “Certificateholders”).

This Certificate is issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of November 1, 2017 (the “Pooling and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities Corp., as Depositor, Wells Fargo Bank, National Association, as Certificate Administrator and as Trustee, Park Bridge Lender Services LLC, as Operating Advisor and as Asset Representations Reviewer, KeyBank National Association, as Master Servicer, and CWCapital Asset Management LLC, as Special Servicer. To the extent not defined herein, capitalized terms used herein shall have the meanings assigned thereto in the Pooling and Servicing Agreement.

This Certificate represents beneficial ownership of a “regular interest” in a “real estate mortgage investment conduit,” as those terms are defined, respectively, in Sections 860G(a)(1) and 860D of the Internal Revenue Code of 1986, as amended.

The Certificate Administrator makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates, the Mortgage Loans or the Trust Subordinate Companion Loans and has executed this Certificate in its limited capacity as Certificate Administrator under the Pooling and Servicing Agreement.

Pursuant to the terms of the Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution on any Certificate), on the 4th Business Day following the determination date of each month, commencing in December 2017 (each such date, a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related Record Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this Certificate) of that portion of the aggregate amount of principal and interest then distributable, if any, allocable to the Class A-SB Certificates for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement. Holders of this Certificate may be entitled to Yield Maintenance Charges, as provided in the Pooling and Servicing Agreement.

Interest accrued on this Certificate during an Interest Accrual Period, plus the aggregate unpaid Interest Shortfall with respect to this Certificate, if any, will be payable on the related Distribution Date to the extent provided in the Pooling and Servicing Agreement. The “Interest Accrual Period” with respect to any Distribution Date and with respect to the Class A-SB Certificates is the calendar month immediately preceding the month in which such Distribution Date occurs and is assumed to consist of 30 days.

All distributions (other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons in whose names the Certificates are registered at the close of business on each Record Date, which will be the close of business on the last Business Day of the month immediately preceding the month in which such Distribution Date occurs.

 A-6-3

Distributions are required to be made (a) by wire transfer of immediately available funds to the account of such Certificateholder at a bank or other entity having appropriate facilities therefor, if such Certificateholder provided the Certificate Administrator with written wiring instructions no less than five Business Days prior to the related Record Date (which wiring instructions may be in the form of a standing order applicable to all subsequent Distribution Dates), or otherwise (b) by check mailed to such Certificateholder at its address in the Certificate Register. The final distribution on each Certificate will be made in like manner, but only upon presentment and surrender of such Certificate at the offices of the Certificate Registrar or such other location specified in the notice to Certificateholders of such final distribution.

Any funds not distributed to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure of such Certificateholders to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited to the account or accounts of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been given pursuant to Section 4.01(l) of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within six months after the time specified in such notice, the Certificate Administrator shall mail a second notice to the remaining non tendering Certificateholders to surrender their Certificates for cancellation in order to receive the final distribution with respect thereto. If within one year after the second notice all such Certificates shall not have been surrendered for cancellation, the Certificate Administrator, directly or through an agent, shall take such steps to contact the remaining non tendering Certificateholders concerning the surrender of their Certificates as it shall deem appropriate and subject to escheatment and other applicable laws. The costs and expenses of holding such funds in trust and of contacting such Certificateholders following the first anniversary of the delivery of such second notice to the non-tendering Certificateholders shall be paid out of such funds.

Notwithstanding the foregoing, no such amendment (A) may change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations of any Mortgage Loan Seller under any Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller or (B) may materially and adversely affect the holders of a Companion Loan without such Companion Holder’s consent.

The Pooling and Servicing Agreement may also be amended from time to time by the parties thereto with the consent of the Holders of Certificates of each Class affected by such amendment (including, for the avoidance of doubt, any Holders of the VRR Interest, the Y&L Towers VRR Interest or the Standard Highline VRR Interest to the extent any such amendment would adversely affect the rights of such Certificateholders) evidencing in the aggregate not less than a majority of the aggregate Percentage Interests constituting the Class for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of the Pooling and Servicing Agreement or of modifying in any manner the rights of the Holders of Certificates of such Class; provided, however, that no such amendment shall:

 A-6-9

Notwithstanding the foregoing, none of the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Depositor, the Master Servicer nor the Special Servicer will be required to consent to any amendment to the Pooling and Servicing Agreement without having first received an Opinion of Counsel (at the Trust’s expense) to the effect that such amendment is permitted under the Pooling and Servicing Agreement, that all conditions precedent have been satisfied and that such amendment or the exercise of any power granted to the Master Servicer, the Special Servicer, the Depositor, the Trustee, the Certificate Administrator, the Operating Advisor, the Asset Representations Reviewer or any other specified person in accordance with such amendment will not result in the imposition of a tax on any portion of the Trust Fund or any Trust REMIC, or cause any Trust REMIC to fail to qualify as a REMIC or cause the Grantor Trust to fail to qualify as a grantor trust under the relevant provisions of the Code.

The Holders of the majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates may, in that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the Certificate Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage Loans (and all property acquired through exercise of remedies in respect of any related Mortgage Loan), the Trust Subordinate Companion Loans and the Trust’s portion of each REO Property remaining in the Trust Fund, and thereby effect termination of the Trust and early retirement of the then-outstanding Certificates, only on or after the first Distribution Date on which the aggregate Stated Principal Balances of the Mortgage Loans, the Trust Subordinate Companion Loans and the portion of any REO Loans held by the Trust is less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage Loans (solely for the purposes of this calculation, if such right is being exercised after December 2027 and the 237 East Fordham Road Mortgage Loan is still an asset of the Trust, then such Mortgage Loan will be excluded from the then-aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate Companion Loans and from the aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate Companion Loans as of the Cut-off Date) as set forth in the Pooling and Servicing Agreement.

Following the date on which the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class A-S, Class X-A, Class X-B, Class X-E, Class B and Class C Regular Interests have been reduced to zero (and provided that there is only one Holder (or multiple Holders acting in unanimity) of the then-outstanding Certificates (other than the Class Z and Class R Certificates)), the Sole Certificateholder shall have the right, with the consent of the Master Servicer, to exchange all of its Certificates (other than the Class Z and Class R Certificates) together with the payment or deemed payment of the Termination Purchase Amount for all of the Mortgage Loans, the Trust Subordinate Companion Loans and each REO Property remaining in the Trust Fund pursuant to the terms of the Pooling and Servicing Agreement.

The obligations created by the Pooling and Servicing Agreement and the Trust created thereby (other than the obligation of the Certificate Administrator to make payments to Certificateholders as provided for in the Pooling and Servicing Agreement), shall terminate upon reduction of the Certificate Balances of all the Certificates to zero (including, without limitation, any such final payment resulting from a termination of the Trust due to a sale of its property) pursuant to the terms of the Pooling and Servicing Agreement. In no event, however, will the

 A-6-10

Trust created by the Pooling and Servicing Agreement continue beyond the expiration of 21 years from the death of the last survivor of the descendants of Joseph P. Kennedy, the late Ambassador of the United States to the Court of St. James, living on the date hereof.

Unless the certificate of authentication hereon has been executed by the Authenticating Agent, by manual signature, this Certificate shall not be entitled to any benefit under the Pooling and Servicing Agreement or be valid for any purpose. The Certificate Registrar has executed this Certificate on behalf of the Trust as Certificate Registrar under the Pooling and Servicing Agreement and makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates, the Mortgage Loans or the Trust Subordinate Companion Loans.

This Certificate is issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of November 1, 2017 (the “Pooling and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities Corp., as Depositor, Wells Fargo Bank, National Association, as Certificate Administrator and as Trustee, Park Bridge Lender Services LLC, as Operating Advisor and as Asset Representations Reviewer, KeyBank National Association, as Master Servicer, and CWCapital Asset Management LLC, as Special Servicer. To the extent not defined herein, capitalized terms used herein shall have the meanings assigned thereto in the Pooling and Servicing Agreement.

This Certificate represents beneficial ownership of a “regular interest” in a “real estate mortgage investment conduit,” as those terms are defined, respectively, in Sections 860G(a)(1) and 860D of the Internal Revenue Code of 1986, as amended.

The Certificate Administrator makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates, the Mortgage Loans or the Trust Subordinate Companion Loans and has executed this Certificate in its limited capacity as Certificate Administrator under the Pooling and Servicing Agreement.

Pursuant to the terms of the Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution on any Certificate), on the 4th Business Day following the determination date of each month, commencing in December 2017 (each such date, a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related Record Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this Certificate) of that portion of the aggregate amount of interest then distributable, if any, allocable to the Class X-A Certificates for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement. Holders of this Certificate may be entitled to Yield Maintenance Charges, as provided in the Pooling and Servicing Agreement.

Interest accrued on this Certificate during an Interest Accrual Period, plus the aggregate unpaid Interest Shortfall with respect to this Certificate, if any, will be payable on the related Distribution Date to the extent provided in the Pooling and Servicing Agreement. The “Interest Accrual Period” with respect to any Distribution Date and with respect to the Class X-A Certificates is the calendar month immediately preceding the month in which such Distribution Date occurs and is assumed to consist of 30 days.

All distributions (other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons in whose names the Certificates are registered at the close of business on each Record Date, which will be the close of business on the last Business Day of the month immediately preceding the month in which such Distribution Date occurs. Distributions are required to be made (a) by wire transfer of immediately available funds to the

 A-7-4

account of such Certificateholder at a bank or other entity having appropriate facilities therefor, if such Certificateholder provided the Certificate Administrator with written wiring instructions no less than five Business Days prior to the related Record Date (which wiring instructions may be in the form of a standing order applicable to all subsequent Distribution Dates), or otherwise (b) by check mailed to such Certificateholder at its address in the Certificate Register. The final distribution on each Certificate will be made in like manner, but only upon presentment and surrender of such Certificate at the offices of the Certificate Registrar or such other location specified in the notice to Certificateholders of such final distribution.

Any funds not distributed to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure of such Certificateholders to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited to the account or accounts of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been given pursuant to Section 4.01(l) of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within six months after the time specified in such notice, the Certificate Administrator shall mail a second notice to the remaining non tendering Certificateholders to surrender their Certificates for cancellation in order to receive the final distribution with respect thereto. If within one year after the second notice all such Certificates shall not have been surrendered for cancellation, the Certificate Administrator, directly or through an agent, shall take such steps to contact the remaining non tendering Certificateholders concerning the surrender of their Certificates as it shall deem appropriate and subject to escheatment and other applicable laws. The costs and expenses of holding such funds in trust and of contacting such Certificateholders following the first anniversary of the delivery of such second notice to the non-tendering Certificateholders shall be paid out of such funds. No interest shall accrue or be payable to any Certificateholder on any amount held in trust under the Pooling and Servicing Agreement by the Certificate Administrator as a result of such Certificateholder’s failure to surrender its Certificate(s) for final payment thereof in accordance with Section 4.01(l) of the Pooling and Servicing Agreement.

This Certificate is limited in right of payment to, among other things, certain collections and recoveries in respect of the Mortgage Loans, as more specifically set forth herein and in the Pooling and Servicing Agreement.

As provided in the Pooling and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject to the Pooling and Servicing Agreement (including any Qualified Substitute Mortgage Loan replacing a removed Mortgage Loan) and the Trust Subordinate Companion Loans, together with the Mortgage Files relating thereto (subject to, in the case of a Serviced Whole Loan, the interests of the related Serviced Companion Noteholder in the related Mortgage File); (ii) all scheduled or unscheduled payments on or collections in respect of the Mortgage Loans and the Trust Subordinate Companion Loans due after the Cut-off Date (or with respect to a Qualified Substitute Mortgage Loan, the Due Date in the month of substitution); (iii) any REO Property (to the extent of the Trust’s interest therein) or the Trust’s beneficial interest in the Mortgaged Property securing a Non Serviced Whole Loan acquired under the related Non-Serviced PSA; (iv) all revenues received in respect of any REO Property (to the extent of the Trust’s interest therein); (v) the Master Servicer’s, the Special Servicer’s, the Certificate Administrator’s and the Trustee’s rights under the insurance policies with respect to the Mortgage Loans and the Trust Subordinate Companion Loans required to be

 A-7-5

(vi) to revise or add any other provisions with respect to matters or questions arising under the Pooling and Servicing Agreement or any other change; provided that the required action shall not adversely affect in any material respect the interests of any Certificateholder (including, for the avoidance of doubt, any Holder of a VRR Interest, a Y&L Towers VRR Interest or a Standard Highline VRR Interest) or any holder of a Serviced Pari Passu Companion Loan not consenting to such revision or addition, as evidenced in writing by an Opinion of Counsel, at the expense of the party requesting such amendment or as evidenced by a Rating Agency Confirmation from each of the Rating Agencies with respect to such amendment or supplement and confirmation of the applicable rating agencies that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings of any class of Serviced Companion Loan Securities, if any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement);

(viii) to modify the provisions of Sections 3.05 and 3.17 of the Pooling and Servicing Agreement (with respect to reimbursement of Nonrecoverable Advances and Workout-Delayed Reimbursement Amounts) if (a) the Depositor, the Master Servicer, the Trustee and, for so long as a Control Termination Event has not occurred and is not continuing and, with respect to any Mortgage Loans other than any Excluded Loan, as to the Directing Holder or, in the case of the Directing Certificateholder, the Holder of a majority of the Controlling Class, the Directing Holder,

 A-7-8

(ix) to modify the procedures of the Pooling and Servicing Agreement relating to compliance with Rule 17g-5 of the Exchange Act; provided that such amendment shall not adversely affect in any material respects the interests of any Certificateholders (including, for the avoidance of doubt, any Holders of a VRR Interest, a Y&L Towers VRR Interest or a Standard Highline VRR Interest), as evidenced by (x) an Opinion of Counsel or (y) if any Certificate is then rated, receipt of Rating Agency Confirmation from each Rating Agency rating such Certificates; and provided, further, that the Certificate Administrator shall give notice of any such amendment to the 17g-5 Information Provider for posting to the 17g-5 Information Provider’s Website pursuant to Section 3.13(c) of the Pooling and Servicing Agreement and the Certificate Administrator shall post such notice to the Certificate Administrator’s Website;

Notwithstanding the foregoing, no such amendment (A) may change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations of any Mortgage Loan Seller under any Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller or (B) may materially and adversely affect the holders of a Companion Loan without such Companion Holder’s consent.

 A-7-9

The Pooling and Servicing Agreement may also be amended from time to time by the parties thereto with the consent of the Holders of Certificates of each Class affected by such amendment (including, for the avoidance of doubt, any Holders of the VRR Interest, the Y&L Towers VRR Interest or the Standard Highline VRR Interest to the extent any such amendment would adversely affect the rights of such Certificateholders) evidencing in the aggregate not less than a majority of the aggregate Percentage Interests constituting the Class for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of the Pooling and Servicing Agreement or of modifying in any manner the rights of the Holders of Certificates of such Class; provided, however, that no such amendment shall:

(i) reduce in any manner the amount of, or delay the timing of, payments received on the Mortgage Loans or the Trust Subordinate Companion Loans that are required to be distributed on a Certificate of any class without the consent of the Holder of the Certificate or which are required to be distributed to a Companion Holder without the consent of such Companion Holder; or

(ii) reduce the aforesaid percentage of Certificates of any Class the Holders of which are required to consent to any such amendment or remove the requirement to obtain consent of any Companion Holder or Holder of Loan-Specific Certificates, in any such case, without the consent of the Holders of all Certificates of such Class then-outstanding or such Companion Holders, as applicable; or

 A-7-10

Notwithstanding the foregoing, none of the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Depositor, the Master Servicer nor the Special Servicer will be required to consent to any amendment to the Pooling and Servicing Agreement without having first received an Opinion of Counsel (at the Trust’s expense) to the effect that such amendment is permitted under the Pooling and Servicing Agreement, that all conditions precedent have been satisfied and that such amendment or the exercise of any power granted to the Master Servicer, the Special Servicer, the Depositor, the Trustee, the Certificate Administrator, the Operating Advisor, the Asset Representations Reviewer or any other specified person in accordance with such amendment will not result in the imposition of a tax on any portion of the Trust Fund or any Trust REMIC, or cause any Trust REMIC to fail to qualify as a REMIC or cause the Grantor Trust to fail to qualify as a grantor trust under the relevant provisions of the Code.

The Holders of the majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates may, in that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the Certificate Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage Loans (and all property acquired through exercise of remedies in respect of any related Mortgage Loan), the Trust Subordinate Companion Loans and the Trust’s portion of each REO Property remaining in the Trust Fund, and thereby effect termination of the Trust and early retirement of the then-outstanding Certificates, only on or after the first Distribution Date on which the aggregate Stated Principal Balances of the Mortgage Loans, the Trust Subordinate Companion Loans and the portion of any REO Loans held by the Trust is less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage Loans (solely for the purposes of this calculation, if such right is being exercised after December 2027 and the 237 East Fordham Road Mortgage Loan is still an asset of the Trust, then such Mortgage Loan will be excluded from the then-aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate Companion Loans and from the aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate Companion Loans as of the Cut-off Date) as set forth in the Pooling and Servicing Agreement.

Following the date on which the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class A-S, Class X-A, Class X-B, Class X-E, Class B and Class C Regular Interests have been reduced to zero (and provided that there is only one Holder (or multiple Holders acting in unanimity) of the then-outstanding Certificates (other than the Class Z and Class R Certificates)), the Sole Certificateholder shall have the right, with the consent of the Master Servicer, to exchange all of its Certificates (other than the Class Z and Class R Certificates) together with the payment or deemed payment of the Termination Purchase Amount for all of the Mortgage Loans, the Trust Subordinate Companion Loans and each REO Property remaining in the Trust Fund pursuant to the terms of the Pooling and Servicing Agreement.

The obligations created by the Pooling and Servicing Agreement and the Trust created thereby (other than the obligation of the Certificate Administrator to make payments to Certificateholders as provided for in the Pooling and Servicing Agreement), shall terminate upon reduction of the Certificate Balances of all the Certificates to zero (including, without limitation, any such final payment resulting from a termination of the Trust due to a sale of its property) pursuant to the terms of the Pooling and Servicing Agreement. In no event, however, will the

 A-7-11

Trust created by the Pooling and Servicing Agreement continue beyond the expiration of 21 years from the death of the last survivor of the descendants of Joseph P. Kennedy, the late Ambassador of the United States to the Court of St. James, living on the date hereof.

Unless the certificate of authentication hereon has been executed by the Authenticating Agent, by manual signature, this Certificate shall not be entitled to any benefit under the Pooling and Servicing Agreement or be valid for any purpose. The Certificate Registrar has executed this Certificate on behalf of the Trust as Certificate Registrar under the Pooling and Servicing Agreement and makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates, the Mortgage Loans or the Trust Subordinate Companion Loans.

The Trust Fund was created, and the Mortgage Loans and the Trust Subordinate Companion Loans are to be serviced, pursuant to the Pooling and Servicing Agreement (as defined below). The Holder of this Certificate, by virtue of the acceptance hereof, assents to the terms, provisions and conditions of the Pooling and Servicing Agreement and is bound thereby.

This Certificate is issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of November 1, 2017 (the “Pooling and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities Corp., as Depositor, Wells Fargo Bank, National Association, as Certificate Administrator and as Trustee, Park Bridge Lender Services LLC, as Operating Advisor and as Asset Representations Reviewer, KeyBank National Association, as Master Servicer, and CWCapital Asset Management LLC, as Special Servicer. To the extent not defined herein, capitalized terms used herein shall have the meanings assigned thereto in the Pooling and Servicing Agreement.

This Certificate represents beneficial ownership of a “regular interest” in a “real estate mortgage investment conduit,” as those terms are defined, respectively, in Sections 860G(a)(1) and 860D of the Internal Revenue Code of 1986, as amended.

The Certificate Administrator makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates, the Mortgage Loans or the Trust Subordinate Companion Loans and has executed this Certificate in its limited capacity as Certificate Administrator under the Pooling and Servicing Agreement.

Pursuant to the terms of the Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution on any Certificate), on the 4th Business Day following the determination date of each month, commencing in December 2017 (each such date, a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related Record Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this Certificate) of that portion of the aggregate amount of interest then distributable, if any, allocable to the Class X-B Certificates for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement. Holders of this Certificate may be entitled to Yield Maintenance Charges, as provided in the Pooling and Servicing Agreement.

Interest accrued on this Certificate during an Interest Accrual Period, plus the aggregate unpaid Interest Shortfall with respect to this Certificate, if any, will be payable on the related Distribution Date to the extent provided in the Pooling and Servicing Agreement. The “Interest Accrual Period” with respect to any Distribution Date and with respect to the Class X-B Certificates is the calendar month immediately preceding the month in which such Distribution Date occurs and is assumed to consist of 30 days.

All distributions (other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons in whose names the Certificates are registered at the close of business on each Record Date, which will be the close of business on the last Business Day of the month immediately preceding the month in which such Distribution Date occurs. Distributions are required to be made (a) by wire transfer of immediately available funds to the account of such Certificateholder at a bank or other entity having appropriate facilities therefor,

 A-8-4

if such Certificateholder provided the Certificate Administrator with written wiring instructions no less than five Business Days prior to the related Record Date (which wiring instructions may be in the form of a standing order applicable to all subsequent Distribution Dates), or otherwise (b) by check mailed to such Certificateholder at its address in the Certificate Register. The final distribution on each Certificate will be made in like manner, but only upon presentment and surrender of such Certificate at the offices of the Certificate Registrar or such other location specified in the notice to Certificateholders of such final distribution.

Any funds not distributed to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure of such Certificateholders to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited to the account or accounts of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been given pursuant to Section 4.01(l) of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within six months after the time specified in such notice, the Certificate Administrator shall mail a second notice to the remaining non tendering Certificateholders to surrender their Certificates for cancellation in order to receive the final distribution with respect thereto. If within one year after the second notice all such Certificates shall not have been surrendered for cancellation, the Certificate Administrator, directly or through an agent, shall take such steps to contact the remaining non tendering Certificateholders concerning the surrender of their Certificates as it shall deem appropriate and subject to escheatment and other applicable laws. The costs and expenses of holding such funds in trust and of contacting such Certificateholders following the first anniversary of the delivery of such second notice to the non-tendering Certificateholders shall be paid out of such funds. No interest shall accrue or be payable to any Certificateholder on any amount held in trust under the Pooling and Servicing Agreement by the Certificate Administrator as a result of such Certificateholder’s failure to surrender its Certificate(s) for final payment thereof in accordance with Section 4.01(l) of the Pooling and Servicing Agreement.

This Certificate is limited in right of payment to, among other things, certain collections and recoveries in respect of the Mortgage Loans, as more specifically set forth herein and in the Pooling and Servicing Agreement.

As provided in the Pooling and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject to the Pooling and Servicing Agreement (including any Qualified Substitute Mortgage Loan replacing a removed Mortgage Loan) and the Trust Subordinate Companion Loans, together with the Mortgage Files relating thereto (subject to, in the case of a Serviced Whole Loan, the interests of the related Serviced Companion Noteholder in the related Mortgage File); (ii) all scheduled or unscheduled payments on or collections in respect of the Mortgage Loans and the Trust Subordinate Companion Loans due after the Cut-off Date (or with respect to a Qualified Substitute Mortgage Loan, the Due Date in the month of substitution); (iii) any REO Property (to the extent of the Trust’s interest therein) or the Trust’s beneficial interest in the Mortgaged Property securing a Non Serviced Whole Loan acquired under the related Non-Serviced PSA; (iv) all revenues received in respect of any REO Property (to the extent of the Trust’s interest therein); (v) the Master Servicer’s, the Special Servicer’s, the Certificate Administrator’s and the Trustee’s rights under the insurance policies with respect to the Mortgage Loans and the Trust Subordinate Companion Loans required to be maintained pursuant to the Pooling and Servicing Agreement and any proceeds thereof (to the

 A-8-5

extent of the Trust’s interest therein); (vi) any Assignment of Leases and any security agreements (to the extent of the Trust’s interest therein); (vii) any letters of credit, indemnities, guaranties or lease enhancement policies given as additional security for any related Mortgage Loans or Trust Subordinate Companion Loans (to the extent of the Trust’s interest therein); (viii) all assets deposited in the Loss of Value Reserve Fund and the Servicing Accounts (to the extent of the Trust’s interest therein), amounts on deposit in the Collection Account (to the extent of the Trust’s interest therein), the Lower-Tier REMIC Distribution Account, the Upper-Tier REMIC Distribution Account, the Trust Subordinate Companion Loan REMIC Distribution Accounts, the Regular Interest Distribution Account, the Excess Interest Distribution Account, the Interest Reserve Account, the Gain-on-Sale Reserve Account (to the extent of the Trust’s interest therein) and any REO Account (to the extent of the Trust’s interest therein), including any reinvestment income, as applicable; (ix) any Environmental Indemnity Agreements (to the extent of the Trust’s interest therein); (x) the rights and remedies of the Depositor under each Mortgage Loan Purchase Agreement (to the extent transferred to the Trustee); (xi) the Lower-Tier Regular Interests; (xii) the Trust Subordinate Companion Loan REMIC Regular Interests; and (xiii) the proceeds of the foregoing (other than any interest earned on deposits in the lock-box accounts, cash collateral accounts, escrow accounts and any reserve accounts, to the extent such interest belongs to the related Mortgagor).

This Certificate does not purport to summarize the Pooling and Servicing Agreement, and reference is made to the Pooling and Servicing Agreement for the interests, rights, benefits, obligations and duties evidenced hereby, and the limitations thereon, and the rights, duties and immunities of the Certificate Administrator and Trustee.

As provided in the Pooling and Servicing Agreement, subject to certain restrictions on transfer set forth therein, upon surrender for registration of transfer of any Certificate, the Certificate Administrator shall execute, authenticate and deliver, in the name of the designated transferee or transferees, one or more new Certificates in authorized denominations, in like aggregate interest and of the same Class.

Prior to due presentation of this Certificate for registration of transfer, the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Certificate Registrar, and any agent of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate Registrar may treat the Person in whose name any Certificate is registered as the owner of such Certificate for the purpose of receiving distributions as provided in the Pooling and Servicing Agreement and for all other purposes whatsoever, and none of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Certificate Registrar, or any agent of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate Registrar shall be affected by any notice to the contrary.

(iii) to change the timing and/or nature of deposits in the Collection Account, the Distribution Accounts or any REO Account; provided that (a) the P&I Advance Date shall in no event be later than the Business Day prior to the related Distribution Date and (b) such change shall not adversely affect in any material respect the interests of any Certificateholder (including, for the avoidance of doubt, any Holder of a VRR Interest, a Y&L Towers VRR Interest or a Standard Highline VRR Interest), as evidenced in writing by an Opinion of Counsel at the expense of the party requesting such amendment or as evidenced by a Rating Agency Confirmation from each Rating Agency with respect to such amendment;

(iv) to modify, eliminate or add to any provisions of the Pooling and Servicing Agreement to such extent as shall be necessary to maintain the qualification of any Trust REMIC as a REMIC or the Grantor Trust as a grantor trust under the relevant provisions of the Code at all times that any Certificate is outstanding, or to avoid or minimize the risk of imposition of any tax on the Trust or any Trust REMIC or the Grantor Trust; provided that the Trustee and the Certificate Administrator have received an Opinion of Counsel (at the expense of the party requesting such amendment) to the effect that (a) such action is necessary or desirable to maintain such qualification or to avoid or minimize the risk of the imposition of any such tax and (b) such action will not adversely affect in any material respect the interests of any Certificateholder (including, for the avoidance of doubt, any Holder of a VRR Interest, a Y&L Towers VRR Interest or a Standard Highline VRR Interest), or Companion Holder;

(v) to modify, eliminate or add to the provisions of Section 5.03(o) of the Pooling and Servicing Agreement or any other provision of the Pooling and Servicing Agreement restricting transfer of the Class R Certificates; provided the Depositor has determined that such change shall not, as evidenced by an Opinion of Counsel, cause the Trust, any Trust REMIC or

(vi) to revise or add any other provisions with respect to matters or questions arising under the Pooling and Servicing Agreement or any other change; provided that the required action shall not adversely affect in any material respect the interests of any Certificateholder (including, for the avoidance of doubt, any Holder of a VRR Interest, a Y&L Towers VRR Interest or a Standard Highline VRR Interest) or any holder of a Serviced Pari Passu Companion Loan not consenting to such revision or addition, as evidenced in writing by an Opinion of Counsel, at the expense of the party requesting such amendment or as evidenced by a Rating Agency Confirmation from each of the Rating Agencies with respect to such amendment or supplement and confirmation of the applicable rating agencies that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings of any class of Serviced Companion Loan Securities, if any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement);

(vii) to amend or supplement any provision of the Pooling and Servicing Agreement to the extent necessary to maintain the then-current ratings assigned to each Class of Certificates by each Rating Agency, as evidenced by a Rating Agency Confirmation from each of the Rating Agencies and confirmation of the applicable rating agencies that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings of any class of Serviced Companion Loan Securities, if any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement); provided that such amendment or supplement shall not adversely affect in any material respect the interests of any Certificateholder (including, for the avoidance of doubt, any Holder of a VRR Interest, a Y&L Towers VRR Interest or a Standard Highline VRR Interest) not consenting to such amendment or supplement, as evidenced by an Opinion of Counsel;

(viii) to modify the provisions of Sections 3.05 and 3.17 of the Pooling and Servicing Agreement (with respect to reimbursement of Nonrecoverable Advances and Workout-Delayed Reimbursement Amounts) if (a) the Depositor, the Master Servicer, the Trustee and, for so long as a Control Termination Event has not occurred and is not continuing and, with respect to any Mortgage Loans other than any Excluded Loan, as to the Directing Holder or, in the case of the Directing Certificateholder, the Holder of a majority of the Controlling Class, the Directing Holder,

 A-8-8

determine that the commercial mortgage backed securities industry standard for such provisions has changed, in order to conform to such industry standard, (b) such modification does not adversely affect the status of any Trust REMIC as a REMIC or the status of the Grantor Trust as a grantor trust under the relevant provisions of the Code, as evidenced by an Opinion of Counsel and (c) each Rating Agency has delivered a Rating Agency Confirmation and, with regard to any class of Serviced Companion Loan Securities, the applicable rating agencies have delivered a confirmation that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement);

(ix) to modify the procedures of the Pooling and Servicing Agreement relating to compliance with Rule 17g-5 of the Exchange Act; provided that such amendment shall not adversely affect in any material respects the interests of any Certificateholders (including, for the avoidance of doubt, any Holders of a VRR Interest, a Y&L Towers VRR Interest or a Standard Highline VRR Interest), as evidenced by (x) an Opinion of Counsel or (y) if any Certificate is then rated, receipt of Rating Agency Confirmation from each Rating Agency rating such Certificates; and provided, further, that the Certificate Administrator shall give notice of any such amendment to the 17g-5 Information Provider for posting to the 17g-5 Information Provider’s Website pursuant to Section 3.13(c) of the Pooling and Servicing Agreement and the Certificate Administrator shall post such notice to the Certificate Administrator’s Website; to modify, eliminate or add to any provisions of the Pooling and Servicing Agreement to such extent as shall be necessary to comply with the requirements for use of Form SF-3 in registered offerings to the extent provided in CFR 239.45(b)(1)(ii), (iii) or (iv); or

(x) to modify, eliminate or add to any of its provisions in the event the Credit Risk Retention Rules or any other regulations applicable to the risk retention requirements for this securitization transaction are amended or repealed, to the extent required to comply with any such amendment or to modify or eliminate the provision related to the risk retention requirements in the event of such repeal.

Notwithstanding the foregoing, no such amendment (A) may change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations of any Mortgage Loan Seller under any Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller or (B) may materially and adversely affect the holders of a Companion Loan without such Companion Holder’s consent.

 A-8-9

The Pooling and Servicing Agreement may also be amended from time to time by the parties thereto with the consent of the Holders of Certificates of each Class affected by such amendment (including, for the avoidance of doubt, any Holders of the VRR Interest, the Y&L Towers VRR Interest or the Standard Highline VRR Interest to the extent any such amendment would adversely affect the rights of such Certificateholders) evidencing in the aggregate not less than a majority of the aggregate Percentage Interests constituting the Class for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of the Pooling and Servicing Agreement or of modifying in any manner the rights of the Holders of Certificates of such Class; provided, however, that no such amendment shall:

(i) reduce in any manner the amount of, or delay the timing of, payments received on the Mortgage Loans or the Trust Subordinate Companion Loans that are required to be distributed on a Certificate of any class without the consent of the Holder of the Certificate or which are required to be distributed to a Companion Holder without the consent of such Companion Holder; or

(ii) reduce the aforesaid percentage of Certificates of any Class the Holders of which are required to consent to any such amendment or remove the requirement to obtain consent of any Companion Holder or Holder of Loan-Specific Certificates, in any such case, without the consent of the Holders of all Certificates of such Class then-outstanding or such Companion Holders, as applicable; or

(iii) adversely affect the Voting Rights of any Class of Certificates without the consent of the Holders of all Certificates of such Class then outstanding; or

(iv) change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations of any Mortgage Loan Seller under such Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller; or

(v) amend the Servicing Standard without the consent of 100% of the Certificateholders or receipt of Rating Agency Confirmation from each Rating Agency and confirmation of the applicable rating agencies that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings of any Serviced Companion Loan Securities, if any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement) and, if required under the related Intercreditor Agreement, the consent of the holder of any AB Subordinate Companion Loan for each Serviced AB Whole Loan.

 A-8-10

Notwithstanding the foregoing, none of the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Depositor, the Master Servicer nor the Special Servicer will be required to consent to any amendment to the Pooling and Servicing Agreement without having first received an Opinion of Counsel (at the Trust’s expense) to the effect that such amendment is permitted under the Pooling and Servicing Agreement, that all conditions precedent have been satisfied and that such amendment or the exercise of any power granted to the Master Servicer, the Special Servicer, the Depositor, the Trustee, the Certificate Administrator, the Operating Advisor, the Asset Representations Reviewer or any other specified person in accordance with such amendment will not result in the imposition of a tax on any portion of the Trust Fund or any Trust REMIC, or cause any Trust REMIC to fail to qualify as a REMIC or cause the Grantor Trust to fail to qualify as a grantor trust under the relevant provisions of the Code.

The Holders of the majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates may, in that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the Certificate Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage Loans (and all property acquired through exercise of remedies in respect of any related Mortgage Loan), the Trust Subordinate Companion Loans and the Trust’s portion of each REO Property remaining in the Trust Fund, and thereby effect termination of the Trust and early retirement of the then-outstanding Certificates, only on or after the first Distribution Date on which the aggregate Stated Principal Balances of the Mortgage Loans, the Trust Subordinate Companion Loans and the portion of any REO Loans held by the Trust is less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage Loans (solely for the purposes of this calculation, if such right is being exercised after December 2027 and the 237 East Fordham Road Mortgage Loan is still an asset of the Trust, then such Mortgage Loan will be excluded from the then-aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate Companion Loans and from the aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate Companion Loans as of the Cut-off Date) as set forth in the Pooling and Servicing Agreement.

Following the date on which the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class A-S, Class X-A, Class X-B, Class X-E, Class B and Class C Regular Interests have been reduced to zero (and provided that there is only one Holder (or multiple Holders acting in unanimity) of the then-outstanding Certificates (other than the Class Z and Class R Certificates)), the Sole Certificateholder shall have the right, with the consent of the Master Servicer, to exchange all of its Certificates (other than the Class Z and Class R Certificates) together with the payment or deemed payment of the Termination Purchase Amount for all of the Mortgage Loans, the Trust Subordinate Companion Loans and each REO Property remaining in the Trust Fund pursuant to the terms of the Pooling and Servicing Agreement.

The obligations created by the Pooling and Servicing Agreement and the Trust created thereby (other than the obligation of the Certificate Administrator to make payments to Certificateholders as provided for in the Pooling and Servicing Agreement), shall terminate upon reduction of the Certificate Balances of all the Certificates to zero (including, without limitation, any such final payment resulting from a termination of the Trust due to a sale of its property) pursuant to the terms of the Pooling and Servicing Agreement. In no event, however, will the

 A-8-11

Trust created by the Pooling and Servicing Agreement continue beyond the expiration of 21 years from the death of the last survivor of the descendants of Joseph P. Kennedy, the late Ambassador of the United States to the Court of St. James, living on the date hereof.

Unless the certificate of authentication hereon has been executed by the Authenticating Agent, by manual signature, this Certificate shall not be entitled to any benefit under the Pooling and Servicing Agreement or be valid for any purpose. The Certificate Registrar has executed this Certificate on behalf of the Trust as Certificate Registrar under the Pooling and Servicing Agreement and makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates, the Mortgage Loans or the Trust Subordinate Companion Loans.

The Trust Fund, described more fully below, consists primarily of a pool of Mortgage Loans secured by first liens on commercial and multifamily properties and subordinate interests in two subordinate companion loans (the “Trust Subordinate Companion Loans”) held in trust by the Trustee and serviced by the Master Servicer. The Trust Fund was created, and the Mortgage Loans and the Trust Subordinate Companion Loans are to be serviced, pursuant to the Pooling and Servicing Agreement (as defined below). The Holder of this Certificate, by virtue of the acceptance hereof, assents to the terms, provisions and conditions of the Pooling and Servicing Agreement and is bound thereby. In the event that there is any conflict between any provision of this Certificate and any provision of the Pooling and Servicing Agreement, such provision of this Certificate shall be superseded to the extent of such inconsistency. Also issued under the Pooling and Servicing Agreement are the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class X-A, Class X-B, Class A-S, Class B, Class C, Class D, Class E, Class F, Class NR, Class V1-A, Class V1-B, Class V1-D, Class V1-E, Class V1-F, Class V1-Z, Class V2-A, Class V2-Z, Class UES-A, Class UES-B, Class UES-C, Class UES-D, Class UES-X, Class STN-A, Class STN-B, Class STN-X, Class STN-C, Class V1-UESA, Class V1-UESD, Class V2-UES, Class V1-STNA, Class V1-STNC, Class V2-STN, Class R and Class Z Certificates (together with the Class X-E Certificates, the “Certificates”; the Holders of Certificates are collectively referred to herein as “Certificateholders”).

This Certificate is issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of November 1, 2017 (the “Pooling and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities Corp., as Depositor, Wells Fargo Bank, National Association, as Certificate Administrator and as Trustee, Park Bridge Lender Services LLC, as Operating Advisor and as Asset Representations Reviewer, KeyBank National Association, as Master Servicer, and CWCapital Asset Management LLC, as Special Servicer. To the extent not defined herein, capitalized terms used herein shall have the meanings assigned thereto in the Pooling and Servicing Agreement.

This Certificate represents beneficial ownership of a “regular interest” in a “real estate mortgage investment conduit,” as those terms are defined, respectively, in Sections 860G(a)(1) and 860D of the Internal Revenue Code of 1986, as amended.

The Certificate Administrator makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates, the Mortgage Loans or the Trust Subordinate Companion Loans and has executed this Certificate in its limited capacity as Certificate Administrator under the Pooling and Servicing Agreement.

Pursuant to the terms of the Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution on any Certificate), on the 4th Business Day following the determination date of each month, commencing in December 2017 (each such date, a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related Record Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this Certificate) of that portion of the aggregate amount of interest then distributable, if any, allocable to the Class X-E Certificates for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement.

Interest accrued on this Certificate during an Interest Accrual Period, plus the aggregate unpaid Interest Shortfall with respect to this Certificate, if any, will be payable on the related

 A-9-4

Distribution Date to the extent provided in the Pooling and Servicing Agreement. The “Interest Accrual Period” with respect to any Distribution Date and with respect to the Class X-E Certificates is the calendar month immediately preceding the month in which such Distribution Date occurs and is assumed to consist of 30 days.

All distributions (other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons in whose names the Certificates are registered at the close of business on each Record Date, which will be the close of business on the last Business Day of the month immediately preceding the month in which such Distribution Date occurs. Distributions are required to be made (a) by wire transfer of immediately available funds to the account of such Certificateholder at a bank or other entity having appropriate facilities therefor, if such Certificateholder provided the Certificate Administrator with written wiring instructions no less than five Business Days prior to the related Record Date (which wiring instructions may be in the form of a standing order applicable to all subsequent Distribution Dates), or otherwise (b) by check mailed to such Certificateholder at its address in the Certificate Register. The final distribution on each Certificate will be made in like manner, but only upon presentment and surrender of such Certificate at the offices of the Certificate Registrar or such other location specified in the notice to Certificateholders of such final distribution.

Any funds not distributed to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure of such Certificateholders to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited to the account or accounts of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been given pursuant to Section 4.01(l) of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within six months after the time specified in such notice, the Certificate Administrator shall mail a second notice to the remaining non tendering Certificateholders to surrender their Certificates for cancellation in order to receive the final distribution with respect thereto. If within one year after the second notice all such Certificates shall not have been surrendered for cancellation, the Certificate Administrator, directly or through an agent, shall take such steps to contact the remaining non tendering Certificateholders concerning the surrender of their Certificates as it shall deem appropriate and subject to escheatment and other applicable laws. The costs and expenses of holding such funds in trust and of contacting such Certificateholders following the first anniversary of the delivery of such second notice to the non-tendering Certificateholders shall be paid out of such funds. No interest shall accrue or be payable to any Certificateholder on any amount held in trust under the Pooling and Servicing Agreement by the Certificate Administrator as a result of such Certificateholder’s failure to surrender its Certificate(s) for final payment thereof in accordance with Section 4.01(l) of the Pooling and Servicing Agreement.

This Certificate is limited in right of payment to, among other things, certain collections and recoveries in respect of the Mortgage Loans, as more specifically set forth herein and in the Pooling and Servicing Agreement.

As provided in the Pooling and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject to the Pooling and Servicing Agreement (including any Qualified Substitute Mortgage Loan replacing a removed Mortgage Loan) and the Trust Subordinate Companion Loans, together with the Mortgage Files relating thereto (subject to, in the case of a Serviced Whole Loan, the interests of the related Serviced Companion

 A-9-5

Noteholder in the related Mortgage File); (ii) all scheduled or unscheduled payments on or collections in respect of the Mortgage Loans and the Trust Subordinate Companion Loans due after the Cut-off Date (or with respect to a Qualified Substitute Mortgage Loan, the Due Date in the month of substitution); (iii) any REO Property (to the extent of the Trust’s interest therein) or the Trust’s beneficial interest in the Mortgaged Property securing a Non Serviced Whole Loan acquired under the related Non-Serviced PSA; (iv) all revenues received in respect of any REO Property (to the extent of the Trust’s interest therein); (v) the Master Servicer’s, the Special Servicer’s, the Certificate Administrator’s and the Trustee’s rights under the insurance policies with respect to the Mortgage Loans and the Trust Subordinate Companion Loans required to be maintained pursuant to the Pooling and Servicing Agreement and any proceeds thereof (to the extent of the Trust’s interest therein); (vi) any Assignment of Leases and any security agreements (to the extent of the Trust’s interest therein); (vii) any letters of credit, indemnities, guaranties or lease enhancement policies given as additional security for any related Mortgage Loans or Trust Subordinate Companion Loans (to the extent of the Trust’s interest therein); (viii) all assets deposited in the Loss of Value Reserve Fund and the Servicing Accounts (to the extent of the Trust’s interest therein), amounts on deposit in the Collection Account (to the extent of the Trust’s interest therein), the Lower-Tier REMIC Distribution Account, the Upper-Tier REMIC Distribution Account, the Trust Subordinate Companion Loan REMIC Distribution Accounts, the Regular Interest Distribution Account, the Excess Interest Distribution Account, the Interest Reserve Account, the Gain-on-Sale Reserve Account (to the extent of the Trust’s interest therein) and any REO Account (to the extent of the Trust’s interest therein), including any reinvestment income, as applicable; (ix) any Environmental Indemnity Agreements (to the extent of the Trust’s interest therein); (x) the rights and remedies of the Depositor under each Mortgage Loan Purchase Agreement (to the extent transferred to the Trustee); (xi) the Lower-Tier Regular Interests; (xii) the Trust Subordinate Companion Loan REMIC Regular Interests; and (xiii) the proceeds of the foregoing (other than any interest earned on deposits in the lock-box accounts, cash collateral accounts, escrow accounts and any reserve accounts, to the extent such interest belongs to the related Mortgagor).

This Certificate does not purport to summarize the Pooling and Servicing Agreement, and reference is made to the Pooling and Servicing Agreement for the interests, rights, benefits, obligations and duties evidenced hereby, and the limitations thereon, and the rights, duties and immunities of the Certificate Administrator and Trustee.

As provided in the Pooling and Servicing Agreement, subject to certain restrictions on transfer set forth therein, upon surrender for registration of transfer of any Certificate, the Certificate Administrator shall execute, authenticate and deliver, in the name of the designated transferee or transferees, one or more new Certificates in authorized denominations, in like aggregate interest and of the same Class.

Prior to due presentation of this Certificate for registration of transfer, the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Certificate Registrar, and any agent of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate Registrar may treat the Person in whose name any Certificate is registered as the owner of such Certificate for the purpose of receiving distributions as provided in the Pooling and Servicing Agreement and for all other purposes whatsoever, and

 A-9-6

none of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Certificate Registrar, or any agent of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate Registrar shall be affected by any notice to the contrary.

The Pooling and Servicing Agreement may be amended from time to time by the Depositor, the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Certificate Administrator and the Trustee, without the consent of any of the Certificateholders or the Companion Holders:

 A-9-7

(i) to correct any defect or ambiguity in the Pooling and Servicing Agreement;

 A-9-9

as a grantor trust under the relevant provisions of the Code, as evidenced by an Opinion of Counsel and (c) each Rating Agency has delivered a Rating Agency Confirmation and, with regard to any class of Serviced Companion Loan Securities, the applicable rating agencies have delivered a confirmation that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement);

(ix) to modify the procedures of the Pooling and Servicing Agreement relating to compliance with Rule 17g-5 of the Exchange Act; provided that such amendment shall not adversely affect in any material respects the interests of any Certificateholders (including, for the avoidance of doubt, any Holders of a VRR Interest, a Y&L Towers VRR Interest or a Standard Highline VRR Interest), as evidenced by (x) an Opinion of Counsel or (y) if any Certificate is then rated, receipt of Rating Agency Confirmation from each Rating Agency rating such Certificates; and provided, further, that the Certificate Administrator shall give notice of any such amendment to the 17g-5 Information Provider for posting to the 17g-5 Information Provider’s Website pursuant to Section 3.13(c) of the Pooling and Servicing Agreement and the Certificate Administrator shall post such notice to the Certificate Administrator’s Website;

(xi) to modify, eliminate or add to any of its provisions in the event the Credit Risk Retention Rules or any other regulations applicable to the risk retention requirements for this securitization transaction are amended or repealed, to the extent required to comply with any such amendment or to modify or eliminate the provision related to the risk retention requirements in the event of such repeal.

Notwithstanding the foregoing, no such amendment (A) may change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations of any Mortgage Loan Seller under any Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller or (B) may materially and adversely affect the holders of a Companion Loan without such Companion Holder’s consent.

The Pooling and Servicing Agreement may also be amended from time to time by the parties thereto with the consent of the Holders of Certificates of each Class affected by such amendment (including, for the avoidance of doubt, any Holders of the VRR Interest, the Y&L Towers VRR

 A-9-10

Interest or the Standard Highline VRR Interest to the extent any such amendment would adversely affect the rights of such Certificateholders) evidencing in the aggregate not less than a majority of the aggregate Percentage Interests constituting the Class for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of the Pooling and Servicing Agreement or of modifying in any manner the rights of the Holders of Certificates of such Class; provided, however, that no such amendment shall:

(i) reduce in any manner the amount of, or delay the timing of, payments received on the Mortgage Loans or the Trust Subordinate Companion Loans that are required to be distributed on a Certificate of any class without the consent of the Holder of the Certificate or which are required to be distributed to a Companion Holder without the consent of such Companion Holder; or

(ii) reduce the aforesaid percentage of Certificates of any Class the Holders of which are required to consent to any such amendment or remove the requirement to obtain consent of any Companion Holder or Holder of Loan-Specific Certificates, in any such case, without the consent of the Holders of all Certificates of such Class then-outstanding or such Companion Holders, as applicable; or

(iii) adversely affect the Voting Rights of any Class of Certificates without the consent of the Holders of all Certificates of such Class then outstanding; or

(iv) change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations of any Mortgage Loan Seller under such Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller; or

(v) amend the Servicing Standard without the consent of 100% of the Certificateholders or receipt of Rating Agency Confirmation from each Rating Agency and confirmation of the applicable rating agencies that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings of any Serviced Companion Loan Securities, if any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement) and, if required under the related Intercreditor Agreement, the consent of the holder of any AB Subordinate Companion Loan for each Serviced AB Whole Loan.

Notwithstanding the foregoing, none of the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Depositor, the Master Servicer nor the Special Servicer will be required to consent to any amendment to the Pooling and Servicing Agreement without having first received an Opinion of Counsel (at the Trust’s expense) to the

 A-9-11

effect that such amendment is permitted under the Pooling and Servicing Agreement, that all conditions precedent have been satisfied and that such amendment or the exercise of any power granted to the Master Servicer, the Special Servicer, the Depositor, the Trustee, the Certificate Administrator, the Operating Advisor, the Asset Representations Reviewer or any other specified person in accordance with such amendment will not result in the imposition of a tax on any portion of the Trust Fund or any Trust REMIC, or cause any Trust REMIC to fail to qualify as a REMIC or cause the Grantor Trust to fail to qualify as a grantor trust under the relevant provisions of the Code.

The Holders of the majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates may, in that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the Certificate Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage Loans (and all property acquired through exercise of remedies in respect of any related Mortgage Loan), the Trust Subordinate Companion Loans and the Trust’s portion of each REO Property remaining in the Trust Fund, and thereby effect termination of the Trust and early retirement of the then-outstanding Certificates, only on or after the first Distribution Date on which the aggregate Stated Principal Balances of the Mortgage Loans, the Trust Subordinate Companion Loans and the portion of any REO Loans held by the Trust is less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage Loans (solely for the purposes of this calculation, if such right is being exercised after December 2027 and the 237 East Fordham Road Mortgage Loan is still an asset of the Trust, then such Mortgage Loan will be excluded from the then-aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate Companion Loans and from the aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate Companion Loans as of the Cut-off Date) as set forth in the Pooling and Servicing Agreement.

Following the date on which the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class A-S, Class X-A, Class X-B, Class X-E, Class B and Class C Regular Interests have been reduced to zero (and provided that there is only one Holder (or multiple Holders acting in unanimity) of the then-outstanding Certificates (other than the Class Z and Class R Certificates)), the Sole Certificateholder shall have the right, with the consent of the Master Servicer, to exchange all of its Certificates (other than the Class Z and Class R Certificates) together with the payment or deemed payment of the Termination Purchase Amount for all of the Mortgage Loans, the Trust Subordinate Companion Loans and each REO Property remaining in the Trust Fund pursuant to the terms of the Pooling and Servicing Agreement.

The obligations created by the Pooling and Servicing Agreement and the Trust created thereby (other than the obligation of the Certificate Administrator to make payments to Certificateholders as provided for in the Pooling and Servicing Agreement), shall terminate upon reduction of the Certificate Balances of all the Certificates to zero (including, without limitation, any such final payment resulting from a termination of the Trust due to a sale of its property) pursuant to the terms of the Pooling and Servicing Agreement. In no event, however, will the Trust created by the Pooling and Servicing Agreement continue beyond the expiration of 21 years from the death of the last survivor of the descendants of Joseph P. Kennedy, the late Ambassador of the United States to the Court of St. James, living on the date hereof.

This certifies that [           ] is the registered owner of a beneficial ownership interest in a Trust Fund, including the distributions to be made with respect to the Class A-S Certificates. The Trust Fund, described more fully below, consists primarily of a pool of Mortgage Loans secured by first liens on commercial and multifamily properties and subordinate interests in two subordinate companion loans (the “Trust Subordinate Companion Loans”) held in trust by the Trustee and serviced by the Master Servicer. The Trust Fund was created, and the Mortgage Loans and the Trust Subordinate Companion Loans are to be serviced, pursuant to the Pooling and Servicing Agreement (as defined below). The Holder of this Certificate, by virtue of the acceptance hereof, assents to the terms, provisions and conditions of the Pooling and Servicing Agreement and is bound thereby. In the event that there is any conflict between any provision of this Certificate and any provision of the Pooling and Servicing Agreement, such provision of this Certificate shall be superseded to the extent of such inconsistency. Also issued under the Pooling and Servicing Agreement are the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class X-A, Class X-B, Class X-E, Class B, Class C, Class D, Class E, Class F,

A-10-3

Class NR, Class V1-A, Class V1-B, Class V1-D, Class V1-E, Class V1-F, Class V1-Z, Class V2-A, Class V2-Z, Class UES-A, Class UES-B, Class UES-C, Class UES-D, Class UES-X, Class STN-A, Class STN-B, Class STN-X, Class STN-C, Class V1-UESA, Class V1-UESD, Class V2-UES, Class V1-STNA, Class V1-STNC, Class V2-STN, Class R and Class Z Certificates (together with the Class A-S Certificates, the “Certificates”; the Holders of Certificates are collectively referred to herein as “Certificateholders”).

This Certificate is issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of November 1, 2017 (the “Pooling and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities Corp., as Depositor, Wells Fargo Bank, National Association, as Certificate Administrator and as Trustee, Park Bridge Lender Services LLC, as Operating Advisor and as Asset Representations Reviewer, KeyBank National Association, as Master Servicer, and CWCapital Asset Management LLC, as Special Servicer. To the extent not defined herein, capitalized terms used herein shall have the meanings assigned thereto in the Pooling and Servicing Agreement.

This Certificate represents beneficial ownership of a “regular interest” in a “real estate mortgage investment conduit,” as those terms are defined, respectively, in Sections 860G(a)(1) and 860D of the Internal Revenue Code of 1986, as amended.

The Certificate Administrator makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates, the Mortgage Loans or the Trust Subordinate Companion Loans and has executed this Certificate in its limited capacity as Certificate Administrator under the Pooling and Servicing Agreement.

Pursuant to the terms of the Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution on any Certificate), on the 4th Business Day following the determination date of each month, commencing in December 2017 (each such date, a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related Record Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this Certificate) of that portion of the aggregate amount of principal and interest then distributable, if any, allocable to the Class A-S Certificates for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement. Holders of this Certificate may be entitled to Yield Maintenance Charges, as provided in the Pooling and Servicing Agreement.

Interest accrued on this Certificate during an Interest Accrual Period, plus the aggregate unpaid Interest Shortfall with respect to this Certificate, if any, will be payable on the related Distribution Date to the extent provided in the Pooling and Servicing Agreement. The “Interest Accrual Period” with respect to any Distribution Date and with respect to the Class A-S Certificates is the calendar month immediately preceding the month in which such Distribution Date occurs and is assumed to consist of 30 days.

All distributions (other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons in whose names the Certificates are registered at the close of business on each Record Date, which will be the close of business on the last Business Day of the month immediately preceding the month in which such Distribution Date occurs. Distributions are required to be made (a) by wire transfer of immediately available funds to the

A-10-4

account of such Certificateholder at a bank or other entity having appropriate facilities therefor, if such Certificateholder provided the Certificate Administrator with written wiring instructions no less than five Business Days prior to the related Record Date (which wiring instructions may be in the form of a standing order applicable to all subsequent Distribution Dates), or otherwise (b) by check mailed to such Certificateholder at its address in the Certificate Register. The final distribution on each Certificate will be made in like manner, but only upon presentment and surrender of such Certificate at the offices of the Certificate Registrar or such other location specified in the notice to Certificateholders of such final distribution.

Any funds not distributed to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure of such Certificateholders to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited to the account or accounts of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been given pursuant to Section 4.01(l) of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within six months after the time specified in such notice, the Certificate Administrator shall mail a second notice to the remaining non tendering Certificateholders to surrender their Certificates for cancellation in order to receive the final distribution with respect thereto. If within one year after the second notice all such Certificates shall not have been surrendered for cancellation, the Certificate Administrator, directly or through an agent, shall take such steps to contact the remaining non tendering Certificateholders concerning the surrender of their Certificates as it shall deem appropriate and subject to escheatment and other applicable laws. The costs and expenses of holding such funds in trust and of contacting such Certificateholders following the first anniversary of the delivery of such second notice to the non-tendering Certificateholders shall be paid out of such funds. No interest shall accrue or be payable to any Certificateholder on any amount held in trust under the Pooling and Servicing Agreement by the Certificate Administrator as a result of such Certificateholder’s failure to surrender its Certificate(s) for final payment thereof in accordance with Section 4.01(l) of the Pooling and Servicing Agreement.

This Certificate is limited in right of payment to, among other things, certain collections and recoveries in respect of the Mortgage Loans, as more specifically set forth herein and in the Pooling and Servicing Agreement.

As provided in the Pooling and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject to the Pooling and Servicing Agreement (including any Qualified Substitute Mortgage Loan replacing a removed Mortgage Loan) and the Trust Subordinate Companion Loans, together with the Mortgage Files relating thereto (subject to, in the case of a Serviced Whole Loan, the interests of the related Serviced Companion Noteholder in the related Mortgage File); (ii) all scheduled or unscheduled payments on or collections in respect of the Mortgage Loans and the Trust Subordinate Companion Loans due after the Cut-off Date (or with respect to a Qualified Substitute Mortgage Loan, the Due Date in the month of substitution); (iii) any REO Property (to the extent of the Trust’s interest therein) or the Trust’s beneficial interest in the Mortgaged Property securing a Non Serviced Whole Loan acquired under the related Non-Serviced PSA; (iv) all revenues received in respect of any REO Property (to the extent of the Trust’s interest therein); (v) the Master Servicer’s, the Special Servicer’s, the Certificate Administrator’s and the Trustee’s rights under the insurance policies with respect to the Mortgage Loans and the Trust Subordinate Companion Loans required to be

A-10-5

maintained pursuant to the Pooling and Servicing Agreement and any proceeds thereof (to the extent of the Trust’s interest therein); (vi) any Assignment of Leases and any security agreements (to the extent of the Trust’s interest therein); (vii) any letters of credit, indemnities, guaranties or lease enhancement policies given as additional security for any related Mortgage Loans or Trust Subordinate Companion Loans (to the extent of the Trust’s interest therein); (viii) all assets deposited in the Loss of Value Reserve Fund and the Servicing Accounts (to the extent of the Trust’s interest therein), amounts on deposit in the Collection Account (to the extent of the Trust’s interest therein), the Lower-Tier REMIC Distribution Account, the Upper-Tier REMIC Distribution Account, the Trust Subordinate Companion Loan REMIC Distribution Accounts, the Regular Interest Distribution Account, the Excess Interest Distribution Account, the Interest Reserve Account, the Gain-on-Sale Reserve Account (to the extent of the Trust’s interest therein) and any REO Account (to the extent of the Trust’s interest therein), including any reinvestment income, as applicable; (ix) any Environmental Indemnity Agreements (to the extent of the Trust’s interest therein); (x) the rights and remedies of the Depositor under each Mortgage Loan Purchase Agreement (to the extent transferred to the Trustee); (xi) the Lower-Tier Regular Interests; (xii) the Trust Subordinate Companion Loan REMIC Regular Interests; and (xiii) the proceeds of the foregoing (other than any interest earned on deposits in the lock-box accounts, cash collateral accounts, escrow accounts and any reserve accounts, to the extent such interest belongs to the related Mortgagor).

This Certificate does not purport to summarize the Pooling and Servicing Agreement, and reference is made to the Pooling and Servicing Agreement for the interests, rights, benefits, obligations and duties evidenced hereby, and the limitations thereon, and the rights, duties and immunities of the Certificate Administrator and Trustee.

As provided in the Pooling and Servicing Agreement, subject to certain restrictions on transfer set forth therein, upon surrender for registration of transfer of any Certificate, the Certificate Administrator shall execute, authenticate and deliver, in the name of the designated transferee or transferees, one or more new Certificates in authorized denominations, in like aggregate interest and of the same Class.

Prior to due presentation of this Certificate for registration of transfer, the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Certificate Registrar, and any agent of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate Registrar may treat the Person in whose name any Certificate is registered as the owner of such Certificate for the purpose of receiving distributions as provided in the Pooling and Servicing Agreement and for all other purposes whatsoever, and none of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Certificate Registrar, or any agent of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate Registrar shall be affected by any notice to the contrary.

A-10-6

The Pooling and Servicing Agreement may be amended from time to time by the Depositor, the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Certificate Administrator and the Trustee, without the consent of any of the Certificateholders or the Companion Holders:

(i) to correct any defect or ambiguity in the Pooling and Servicing Agreement;

(ii) to cause the provisions in the Pooling and Servicing Agreement to conform or be consistent with or in furtherance of the statements made in the Prospectus (or in an offering document for any related non-offered certificates) with respect to the Certificates, the Trust or the Pooling and Servicing Agreement or to correct or supplement any of its provisions which may be inconsistent with any other provisions therein or to correct any error;

(iii) to change the timing and/or nature of deposits in the Collection Account, the Distribution Accounts or any REO Account; provided that (a) the P&I Advance Date shall in no event be later than the Business Day prior to the related Distribution Date and (b) such change shall not adversely affect in any material respect the interests of any Certificateholder (including, for the avoidance of doubt, any Holder of a VRR Interest, a Y&L Towers VRR Interest or a Standard Highline VRR Interest), as evidenced in writing by an Opinion of Counsel at the expense of the party requesting such amendment or as evidenced by a Rating Agency Confirmation from each Rating Agency with respect to such amendment;

(iv) to modify, eliminate or add to any provisions of the Pooling and Servicing Agreement to such extent as shall be necessary to maintain the qualification of any Trust REMIC as a REMIC or the Grantor Trust as a grantor trust under the relevant provisions of the Code at all times that any Certificate is outstanding, or to avoid or minimize the risk of imposition of any tax on the Trust or any Trust REMIC or the Grantor Trust; provided that the Trustee and the Certificate Administrator have received an Opinion of Counsel (at the expense of the party requesting such amendment) to the effect that (a) such action is necessary or desirable to maintain such qualification or to avoid or minimize the risk of the imposition of any such tax and (b) such action will not adversely affect in any material respect the interests of any Certificateholder (including, for the avoidance of doubt, any Holder of a VRR Interest, a Y&L Towers VRR Interest or a Standard Highline VRR Interest), or Companion Holder;

(v) to modify, eliminate or add to the provisions of Section 5.03(o) of the Pooling and Servicing Agreement or any other provision of the Pooling and Servicing Agreement restricting transfer of the Class R Certificates; provided the Depositor has determined that such change shall not, as evidenced by an Opinion of Counsel, cause the Trust, any Trust REMIC or

A-10-7

(ix) to modify the procedures of the Pooling and Servicing Agreement relating to compliance with Rule 17g-5 of the Exchange Act; provided that such amendment shall not adversely affect in any material respects the interests of any Certificateholders (including, for the avoidance of doubt, any Holders of a VRR Interest, a Y&L Towers VRR Interest or a Standard Highline VRR Interest), as evidenced by (x) an Opinion of Counsel or (y) if any Certificate is then rated, receipt of Rating Agency Confirmation from each Rating Agency rating such Certificates; and provided, further, that the Certificate Administrator shall give notice of any such amendment to the 17g-5 Information Provider for posting to the 17g-5 Information Provider’s Website pursuant to Section 3.13(c) of the Pooling and Servicing Agreement and the Certificate Administrator shall post such notice to the Certificate Administrator’s Website;

(xi) to modify, eliminate or add to any of its provisions in the event the Credit Risk Retention Rules or any other regulations applicable to the risk retention requirements for this securitization transaction are amended or repealed, to the extent required to comply with any such amendment or to modify or eliminate the provision related to the risk retention requirements in the event of such repeal.

Notwithstanding the foregoing, no such amendment (A) may change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations of any Mortgage Loan Seller under any Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller or (B) may materially and adversely affect the holders of a Companion Loan without such Companion Holder’s consent.

A-10-9

The Pooling and Servicing Agreement may also be amended from time to time by the parties thereto with the consent of the Holders of Certificates of each Class affected by such amendment (including, for the avoidance of doubt, any Holders of the VRR Interest, the Y&L Towers VRR Interest or the Standard Highline VRR Interest to the extent any such amendment would adversely affect the rights of such Certificateholders) evidencing in the aggregate not less than a majority of the aggregate Percentage Interests constituting the Class for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of the Pooling and Servicing Agreement or of modifying in any manner the rights of the Holders of Certificates of such Class; provided, however, that no such amendment shall:

A-10-10

Notwithstanding the foregoing, none of the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Depositor, the Master Servicer nor the Special Servicer will be required to consent to any amendment to the Pooling and Servicing Agreement without having first received an Opinion of Counsel (at the Trust’s expense) to the effect that such amendment is permitted under the Pooling and Servicing Agreement, that all conditions precedent have been satisfied and that such amendment or the exercise of any power granted to the Master Servicer, the Special Servicer, the Depositor, the Trustee, the Certificate Administrator, the Operating Advisor, the Asset Representations Reviewer or any other specified person in accordance with such amendment will not result in the imposition of a tax on any portion of the Trust Fund or any Trust REMIC, or cause any Trust REMIC to fail to qualify as a REMIC or cause the Grantor Trust to fail to qualify as a grantor trust under the relevant provisions of the Code.

The Holders of the majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates may, in that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the Certificate Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage Loans (and all property acquired through exercise of remedies in respect of any related Mortgage Loan), the Trust Subordinate Companion Loans and the Trust’s portion of each REO Property remaining in the Trust Fund, and thereby effect termination of the Trust and early retirement of the then-outstanding Certificates, only on or after the first Distribution Date on which the aggregate Stated Principal Balances of the Mortgage Loans, the Trust Subordinate Companion Loans and the portion of any REO Loans held by the Trust is less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage Loans (solely for the purposes of this calculation, if such right is being exercised after December 2027 and the 237 East Fordham Road Mortgage Loan is still an asset of the Trust, then such Mortgage Loan will be excluded from the then-aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate Companion Loans and from the aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate Companion Loans as of the Cut-off Date) as set forth in the Pooling and Servicing Agreement.

Following the date on which the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class A-S, Class X-A, Class X-B, Class X-E, Class B and Class C Regular Interests have been reduced to zero (and provided that there is only one Holder (or multiple Holders acting in unanimity) of the then-outstanding Certificates (other than the Class Z and Class R Certificates)), the Sole Certificateholder shall have the right, with the consent of the Master Servicer, to exchange all of its Certificates (other than the Class Z and Class R Certificates) together with the payment or deemed payment of the Termination Purchase Amount for all of the Mortgage Loans, the Trust Subordinate Companion Loans and each REO Property remaining in the Trust Fund pursuant to the terms of the Pooling and Servicing Agreement.

The obligations created by the Pooling and Servicing Agreement and the Trust created thereby (other than the obligation of the Certificate Administrator to make payments to Certificateholders as provided for in the Pooling and Servicing Agreement), shall terminate upon reduction of the Certificate Balances of all the Certificates to zero (including, without limitation, any such final payment resulting from a termination of the Trust due to a sale of its property) pursuant to the terms of the Pooling and Servicing Agreement. In no event, however, will the

A-10-11

Trust created by the Pooling and Servicing Agreement continue beyond the expiration of 21 years from the death of the last survivor of the descendants of Joseph P. Kennedy, the late Ambassador of the United States to the Court of St. James, living on the date hereof.

Unless the certificate of authentication hereon has been executed by the Authenticating Agent, by manual signature, this Certificate shall not be entitled to any benefit under the Pooling and Servicing Agreement or be valid for any purpose. The Certificate Registrar has executed this Certificate on behalf of the Trust as Certificate Registrar under the Pooling and Servicing Agreement and makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates, the Mortgage Loans or the Trust Subordinate Companion Loans.

This Certificate is issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of November 1, 2017 (the “Pooling and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities Corp., as Depositor, Wells Fargo Bank, National Association, as Certificate Administrator and as Trustee, Park Bridge Lender Services LLC, as Operating Advisor and as Asset Representations Reviewer, KeyBank National Association, as Master Servicer, and CWCapital Asset Management LLC, as Special Servicer. To the extent not defined herein, capitalized terms used herein shall have the meanings assigned thereto in the Pooling and Servicing Agreement.

This Certificate represents beneficial ownership of a “regular interest” in a “real estate mortgage investment conduit,” as those terms are defined, respectively, in Sections 860G(a)(1) and 860D of the Internal Revenue Code of 1986, as amended.

The Certificate Administrator makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates, the Mortgage Loans or the Trust Subordinate Companion Loans and has executed this Certificate in its limited capacity as Certificate Administrator under the Pooling and Servicing Agreement.

Pursuant to the terms of the Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution on any Certificate), on the 4th Business Day following the determination date of each month, commencing in December 2017 (each such date, a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related Record Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this Certificate) of that portion of the aggregate amount of principal and interest then distributable, if any, allocable to the Class B Certificates for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement. Holders of this Certificate may be entitled to Yield Maintenance Charges, as provided in the Pooling and Servicing Agreement.

Interest accrued on this Certificate during an Interest Accrual Period, plus the aggregate unpaid Interest Shortfall with respect to this Certificate, if any, will be payable on the related Distribution Date to the extent provided in the Pooling and Servicing Agreement. The “Interest Accrual Period” with respect to any Distribution Date and with respect to the Class B Certificates is the calendar month immediately preceding the month in which such Distribution Date occurs and is assumed to consist of 30 days.

All distributions (other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons in whose names the Certificates are registered at the close of business on each Record Date, which will be the close of business on the last Business Day of the month immediately preceding the month in which such Distribution Date occurs.

A-11-4

Distributions are required to be made (a) by wire transfer of immediately available funds to the account of such Certificateholder at a bank or other entity having appropriate facilities therefor, if such Certificateholder provided the Certificate Administrator with written wiring instructions no less than five Business Days prior to the related Record Date (which wiring instructions may be in the form of a standing order applicable to all subsequent Distribution Dates), or otherwise (b) by check mailed to such Certificateholder at its address in the Certificate Register. The final distribution on each Certificate will be made in like manner, but only upon presentment and surrender of such Certificate at the offices of the Certificate Registrar or such other location specified in the notice to Certificateholders of such final distribution.

Any funds not distributed to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure of such Certificateholders to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited to the account or accounts of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been given pursuant to Section 4.01(l) of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within six months after the time specified in such notice, the Certificate Administrator shall mail a second notice to the remaining non tendering Certificateholders to surrender their Certificates for cancellation in order to receive the final distribution with respect thereto. If within one year after the second notice all such Certificates shall not have been surrendered for cancellation, the Certificate Administrator, directly or through an agent, shall take such steps to contact the remaining non tendering Certificateholders concerning the surrender of their Certificates as it shall deem appropriate and subject to escheatment and other applicable laws. The costs and expenses of holding such funds in trust and of contacting such Certificateholders following the first anniversary of the delivery of such second notice to the non-tendering Certificateholders shall be paid out of such funds. No interest shall accrue or be payable to any Certificateholder on any amount held in trust under the Pooling and Servicing Agreement by the Certificate Administrator as a result of such Certificateholder’s failure to surrender its Certificate(s) for final payment thereof in accordance with Section 4.01(l) of the Pooling and Servicing Agreement.

This Certificate is limited in right of payment to, among other things, certain collections and recoveries in respect of the Mortgage Loans, as more specifically set forth herein and in the Pooling and Servicing Agreement.

As provided in the Pooling and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject to the Pooling and Servicing Agreement (including any Qualified Substitute Mortgage Loan replacing a removed Mortgage Loan) and the Trust Subordinate Companion Loans, together with the Mortgage Files relating thereto (subject to, in the case of a Serviced Whole Loan, the interests of the related Serviced Companion Noteholder in the related Mortgage File); (ii) all scheduled or unscheduled payments on or collections in respect of the Mortgage Loans and the Trust Subordinate Companion Loans due after the Cut-off Date (or with respect to a Qualified Substitute Mortgage Loan, the Due Date in the month of substitution); (iii) any REO Property (to the extent of the Trust’s interest therein) or the Trust’s beneficial interest in the Mortgaged Property securing a Non Serviced Whole Loan acquired under the related Non-Serviced PSA; (iv) all revenues received in respect of any REO Property (to the extent of the Trust’s interest therein); (v) the Master Servicer’s, the Special Servicer’s, the Certificate Administrator’s and the Trustee’s rights under the insurance policies

A-11-5

with respect to the Mortgage Loans and the Trust Subordinate Companion Loans required to be maintained pursuant to the Pooling and Servicing Agreement and any proceeds thereof (to the extent of the Trust’s interest therein); (vi) any Assignment of Leases and any security agreements (to the extent of the Trust’s interest therein); (vii) any letters of credit, indemnities, guaranties or lease enhancement policies given as additional security for any related Mortgage Loans or Trust Subordinate Companion Loans (to the extent of the Trust’s interest therein); (viii) all assets deposited in the Loss of Value Reserve Fund and the Servicing Accounts (to the extent of the Trust’s interest therein), amounts on deposit in the Collection Account (to the extent of the Trust’s interest therein), the Lower-Tier REMIC Distribution Account, the Upper-Tier REMIC Distribution Account, the Trust Subordinate Companion Loan REMIC Distribution Accounts, the Regular Interest Distribution Account, the Excess Interest Distribution Account, the Interest Reserve Account, the Gain-on-Sale Reserve Account (to the extent of the Trust’s interest therein) and any REO Account (to the extent of the Trust’s interest therein), including any reinvestment income, as applicable; (ix) any Environmental Indemnity Agreements (to the extent of the Trust’s interest therein); (x) the rights and remedies of the Depositor under each Mortgage Loan Purchase Agreement (to the extent transferred to the Trustee); (xi) the Lower-Tier Regular Interests; (xii) the Trust Subordinate Companion Loan REMIC Regular Interests; and (xiii) the proceeds of the foregoing (other than any interest earned on deposits in the lock-box accounts, cash collateral accounts, escrow accounts and any reserve accounts, to the extent such interest belongs to the related Mortgagor).

This Certificate does not purport to summarize the Pooling and Servicing Agreement, and reference is made to the Pooling and Servicing Agreement for the interests, rights, benefits, obligations and duties evidenced hereby, and the limitations thereon, and the rights, duties and immunities of the Certificate Administrator and Trustee.

As provided in the Pooling and Servicing Agreement, subject to certain restrictions on transfer set forth therein, upon surrender for registration of transfer of any Certificate, the Certificate Administrator shall execute, authenticate and deliver, in the name of the designated transferee or transferees, one or more new Certificates in authorized denominations, in like aggregate interest and of the same Class.

Prior to due presentation of this Certificate for registration of transfer, the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Certificate Registrar, and any agent of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate Registrar may treat the Person in whose name any Certificate is registered as the owner of such Certificate for the purpose of receiving distributions as provided in the Pooling and Servicing Agreement and for all other purposes whatsoever, and none of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Certificate Registrar, or any agent of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate Registrar shall be affected by any notice to the contrary.

(ix) to modify the procedures of the Pooling and Servicing Agreement relating to compliance with Rule 17g-5 of the Exchange Act; provided that such amendment shall not adversely affect in any material respects the interests of any Certificateholders (including, for the avoidance of doubt, any Holders of a VRR Interest, a Y&L Towers VRR Interest or a Standard Highline VRR Interest), as evidenced by (x) an Opinion of Counsel or (y) if any Certificate is then rated, receipt of Rating Agency Confirmation from each Rating Agency rating such Certificates; and provided, further, that the Certificate Administrator shall give notice of any such amendment to the 17g-5 Information Provider for posting to the 17g-5 Information Provider’s Website pursuant to Section 3.13(c) of the Pooling and Servicing Agreement and the Certificate Administrator shall post such notice to the Certificate Administrator’s Website;

(x) to modify, eliminate or add to any provisions of the Pooling and Servicing Agreement to such extent as shall be necessary to comply with the requirements for use of Form SF-3 in registered offerings to the extent provided in CFR 239.45(b)(1)(ii), (iii) or (iv); or

(xi) to modify, eliminate or add to any of its provisions in the event the Credit Risk Retention Rules or any other regulations applicable to the risk retention requirements for this securitization transaction are amended or repealed, to the extent required to comply with any such amendment or to modify or eliminate the provision related to the risk retention requirements in the event of such repeal.

Notwithstanding the foregoing, no such amendment (A) may change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations of any Mortgage Loan Seller under any Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller or (B) may materially and adversely affect the holders of a Companion Loan without such Companion Holder’s consent.

A-11-9

The Pooling and Servicing Agreement may also be amended from time to time by the parties thereto with the consent of the Holders of Certificates of each Class affected by such amendment (including, for the avoidance of doubt, any Holders of the VRR Interest, the Y&L Towers VRR Interest or the Standard Highline VRR Interest to the extent any such amendment would adversely affect the rights of such Certificateholders) evidencing in the aggregate not less than a majority of the aggregate Percentage Interests constituting the Class for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of the Pooling and Servicing Agreement or of modifying in any manner the rights of the Holders of Certificates of such Class; provided, however, that no such amendment shall:

(i) reduce in any manner the amount of, or delay the timing of, payments received on the Mortgage Loans or the Trust Subordinate Companion Loans that are required to be distributed on a Certificate of any class without the consent of the Holder of the Certificate or which are required to be distributed to a Companion Holder without the consent of such Companion Holder; or

(ii) reduce the aforesaid percentage of Certificates of any Class the Holders of which are required to consent to any such amendment or remove the requirement to obtain consent of any Companion Holder or Holder of Loan-Specific Certificates, in any such case, without the consent of the Holders of all Certificates of such Class then-outstanding or such Companion Holders, as applicable; or

(iii) adversely affect the Voting Rights of any Class of Certificates without the consent of the Holders of all Certificates of such Class then outstanding; or

(iv) change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations of any Mortgage Loan Seller under such Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller; or

(v) amend the Servicing Standard without the consent of 100% of the Certificateholders or receipt of Rating Agency Confirmation from each Rating Agency and confirmation of the applicable rating agencies that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings of any Serviced Companion Loan Securities, if any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement) and, if required under the related Intercreditor Agreement, the consent of the holder of any AB Subordinate Companion Loan for each Serviced AB Whole Loan.

A-11-10

Notwithstanding the foregoing, none of the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Depositor, the Master Servicer nor the Special Servicer will be required to consent to any amendment to the Pooling and Servicing Agreement without having first received an Opinion of Counsel (at the Trust’s expense) to the effect that such amendment is permitted under the Pooling and Servicing Agreement, that all conditions precedent have been satisfied and that such amendment or the exercise of any power granted to the Master Servicer, the Special Servicer, the Depositor, the Trustee, the Certificate Administrator, the Operating Advisor, the Asset Representations Reviewer or any other specified person in accordance with such amendment will not result in the imposition of a tax on any portion of the Trust Fund or any Trust REMIC, or cause any Trust REMIC to fail to qualify as a REMIC or cause the Grantor Trust to fail to qualify as a grantor trust under the relevant provisions of the Code.

The Holders of the majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates may, in that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the Certificate Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage Loans (and all property acquired through exercise of remedies in respect of any related Mortgage Loan), the Trust Subordinate Companion Loans and the Trust’s portion of each REO Property remaining in the Trust Fund, and thereby effect termination of the Trust and early retirement of the then-outstanding Certificates, only on or after the first Distribution Date on which the aggregate Stated Principal Balances of the Mortgage Loans, the Trust Subordinate Companion Loans and the portion of any REO Loans held by the Trust is less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage Loans (solely for the purposes of this calculation, if such right is being exercised after December 2027 and the 237 East Fordham Road Mortgage Loan is still an asset of the Trust, then such Mortgage Loan will be excluded from the then-aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate Companion Loans and from the aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate Companion Loans as of the Cut-off Date) as set forth in the Pooling and Servicing Agreement.

Following the date on which the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class A-S, Class X-A, Class X-B, Class X-E, Class B and Class C Regular Interests have been reduced to zero (and provided that there is only one Holder (or multiple Holders acting in unanimity) of the then-outstanding Certificates (other than the Class Z and Class R Certificates)), the Sole Certificateholder shall have the right, with the consent of the Master Servicer, to exchange all of its Certificates (other than the Class Z and Class R Certificates) together with the payment or deemed payment of the Termination Purchase Amount for all of the Mortgage Loans, the Trust Subordinate Companion Loans and each REO Property remaining in the Trust Fund pursuant to the terms of the Pooling and Servicing Agreement.

The obligations created by the Pooling and Servicing Agreement and the Trust created thereby (other than the obligation of the Certificate Administrator to make payments to Certificateholders as provided for in the Pooling and Servicing Agreement), shall terminate upon reduction of the Certificate Balances of all the Certificates to zero (including, without limitation, any such final payment resulting from a termination of the Trust due to a sale of its property) pursuant to the terms of the Pooling and Servicing Agreement. In no event, however, will the

A-11-11

Trust created by the Pooling and Servicing Agreement continue beyond the expiration of 21 years from the death of the last survivor of the descendants of Joseph P. Kennedy, the late Ambassador of the United States to the Court of St. James, living on the date hereof.

Unless the certificate of authentication hereon has been executed by the Authenticating Agent, by manual signature, this Certificate shall not be entitled to any benefit under the Pooling and Servicing Agreement or be valid for any purpose. The Certificate Registrar has executed this Certificate on behalf of the Trust as Certificate Registrar under the Pooling and Servicing Agreement and makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates, the Mortgage Loans or the Trust Subordinate Companion Loans.

The Trust Fund, described more fully below, consists primarily of a pool of Mortgage Loans secured by first liens on commercial and multifamily properties and subordinate interests in two subordinate companion loans (the “Trust Subordinate Companion Loans”) held in trust by the Trustee and serviced by the Master Servicer. The Trust Fund was created, and the Mortgage Loans and the Trust Subordinate Companion Loans are to be serviced, pursuant to the Pooling and Servicing Agreement (as defined below). The Holder of this Certificate, by virtue of the acceptance hereof, assents to the terms, provisions and conditions of the Pooling and Servicing Agreement and is bound thereby. In the event that there is any conflict between any provision of this Certificate and any provision of the Pooling and Servicing Agreement, such provision of this Certificate shall be superseded to the extent of such inconsistency. Also issued under the Pooling and Servicing Agreement are the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class X-A, Class X-B, Class X-E, Class A-S, Class B, Class D, Class E, Class F,

This Certificate is issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of November 1, 2017 (the “Pooling and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities Corp., as Depositor, Wells Fargo Bank, National Association, as Certificate Administrator and as Trustee, Park Bridge Lender Services LLC, as Operating Advisor and as Asset Representations Reviewer, KeyBank National Association, as Master Servicer, and CWCapital Asset Management LLC, as Special Servicer. To the extent not defined herein, capitalized terms used herein shall have the meanings assigned thereto in the Pooling and Servicing Agreement.

This Certificate represents beneficial ownership of a “regular interest” in a “real estate mortgage investment conduit,” as those terms are defined, respectively, in Sections 860G(a)(1) and 860D of the Internal Revenue Code of 1986, as amended.

The Certificate Administrator makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates, the Mortgage Loans or the Trust Subordinate Companion Loans and has executed this Certificate in its limited capacity as Certificate Administrator under the Pooling and Servicing Agreement.

Pursuant to the terms of the Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution on any Certificate), on the 4th Business Day following the determination date of each month, commencing in December 2017 (each such date, a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related Record Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this Certificate) of that portion of the aggregate amount of principal and interest then distributable, if any, allocable to the Class C Certificates for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement. Holders of this Certificate may be entitled to Yield Maintenance Charges, as provided in the Pooling and Servicing Agreement.

Interest accrued on this Certificate during an Interest Accrual Period, plus the aggregate unpaid Interest Shortfall with respect to this Certificate, if any, will be payable on the related Distribution Date to the extent provided in the Pooling and Servicing Agreement. The “Interest Accrual Period” with respect to any Distribution Date and with respect to the Class C Certificates is the calendar month immediately preceding the month in which such Distribution Date occurs and is assumed to consist of 30 days.

All distributions (other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons in whose names the Certificates are registered at the close of business on each Record Date, which will be the close of business on the last Business Day of the month immediately preceding the month in which such Distribution Date occurs. Distributions are required to be made (a) by wire transfer of immediately available funds to the

A-12-4

account of such Certificateholder at a bank or other entity having appropriate facilities therefor, if such Certificateholder provided the Certificate Administrator with written wiring instructions no less than five Business Days prior to the related Record Date (which wiring instructions may be in the form of a standing order applicable to all subsequent Distribution Dates), or otherwise (b) by check mailed to such Certificateholder at its address in the Certificate Register. The final distribution on each Certificate will be made in like manner, but only upon presentment and surrender of such Certificate at the offices of the Certificate Registrar or such other location specified in the notice to Certificateholders of such final distribution.

Any funds not distributed to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure of such Certificateholders to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited to the account or accounts of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been given pursuant to Section 4.01(l) of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within six months after the time specified in such notice, the Certificate Administrator shall mail a second notice to the remaining non tendering Certificateholders to surrender their Certificates for cancellation in order to receive the final distribution with respect thereto. If within one year after the second notice all such Certificates shall not have been surrendered for cancellation, the Certificate Administrator, directly or through an agent, shall take such steps to contact the remaining non tendering Certificateholders concerning the surrender of their Certificates as it shall deem appropriate and subject to escheatment and other applicable laws. The costs and expenses of holding such funds in trust and of contacting such Certificateholders following the first anniversary of the delivery of such second notice to the non-tendering Certificateholders shall be paid out of such funds. No interest shall accrue or be payable to any Certificateholder on any amount held in trust under the Pooling and Servicing Agreement by the Certificate Administrator as a result of such Certificateholder’s failure to surrender its Certificate(s) for final payment thereof in accordance with Section 4.01(l) of the Pooling and Servicing Agreement.

This Certificate is limited in right of payment to, among other things, certain collections and recoveries in respect of the Mortgage Loans, as more specifically set forth herein and in the Pooling and Servicing Agreement.

As provided in the Pooling and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject to the Pooling and Servicing Agreement (including any Qualified Substitute Mortgage Loan replacing a removed Mortgage Loan) and the Trust Subordinate Companion Loans, together with the Mortgage Files relating thereto (subject to, in the case of a Serviced Whole Loan, the interests of the related Serviced Companion Noteholder in the related Mortgage File); (ii) all scheduled or unscheduled payments on or collections in respect of the Mortgage Loans and the Trust Subordinate Companion Loans due after the Cut-off Date (or with respect to a Qualified Substitute Mortgage Loan, the Due Date in the month of substitution); (iii) any REO Property (to the extent of the Trust’s interest therein) or the Trust’s beneficial interest in the Mortgaged Property securing a Non Serviced Whole Loan acquired under the related Non-Serviced PSA; (iv) all revenues received in respect of any REO Property (to the extent of the Trust’s interest therein); (v) the Master Servicer’s, the Special Servicer’s, the Certificate Administrator’s and the Trustee’s rights under the insurance policies with respect to the Mortgage Loans and the Trust Subordinate Companion Loans required to be

A-12-5

maintained pursuant to the Pooling and Servicing Agreement and any proceeds thereof (to the extent of the Trust’s interest therein); (vi) any Assignment of Leases and any security agreements (to the extent of the Trust’s interest therein); (vii) any letters of credit, indemnities, guaranties or lease enhancement policies given as additional security for any related Mortgage Loans or Trust Subordinate Companion Loans (to the extent of the Trust’s interest therein); (viii) all assets deposited in the Loss of Value Reserve Fund and the Servicing Accounts (to the extent of the Trust’s interest therein), amounts on deposit in the Collection Account (to the extent of the Trust’s interest therein), the Lower-Tier REMIC Distribution Account, the Upper-Tier REMIC Distribution Account, the Trust Subordinate Companion Loan REMIC Distribution Accounts, the Regular Interest Distribution Account, the Excess Interest Distribution Account, the Interest Reserve Account, the Gain-on-Sale Reserve Account (to the extent of the Trust’s interest therein) and any REO Account (to the extent of the Trust’s interest therein), including any reinvestment income, as applicable; (ix) any Environmental Indemnity Agreements (to the extent of the Trust’s interest therein); (x) the rights and remedies of the Depositor under each Mortgage Loan Purchase Agreement (to the extent transferred to the Trustee); (xi) the Lower-Tier Regular Interests; (xii) the Trust Subordinate Companion Loan REMIC Regular Interests; and (xiii) the proceeds of the foregoing (other than any interest earned on deposits in the lock-box accounts, cash collateral accounts, escrow accounts and any reserve accounts, to the extent such interest belongs to the related Mortgagor).

This Certificate does not purport to summarize the Pooling and Servicing Agreement, and reference is made to the Pooling and Servicing Agreement for the interests, rights, benefits, obligations and duties evidenced hereby, and the limitations thereon, and the rights, duties and immunities of the Certificate Administrator and Trustee.

As provided in the Pooling and Servicing Agreement, subject to certain restrictions on transfer set forth therein, upon surrender for registration of transfer of any Certificate, the Certificate Administrator shall execute, authenticate and deliver, in the name of the designated transferee or transferees, one or more new Certificates in authorized denominations, in like aggregate interest and of the same Class.

Prior to due presentation of this Certificate for registration of transfer, the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Certificate Registrar, and any agent of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate Registrar may treat the Person in whose name any Certificate is registered as the owner of such Certificate for the purpose of receiving distributions as provided in the Pooling and Servicing Agreement and for all other purposes whatsoever, and none of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Certificate Registrar, or any agent of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate Registrar shall be affected by any notice to the contrary.

A-12-6

(iii) to change the timing and/or nature of deposits in the Collection Account, the Distribution Accounts or any REO Account; provided that (a) the P&I Advance Date shall in no event be later than the Business Day prior to the related Distribution Date and (b) such change shall not adversely affect in any material respect the interests of any Certificateholder (including, for the avoidance of doubt, any Holder of a VRR Interest, a Y&L Towers VRR Interest or a Standard Highline VRR Interest), as evidenced in writing by an Opinion of Counsel at the expense of the party requesting such amendment or as evidenced by a Rating Agency Confirmation from each Rating Agency with respect to such amendment;

(iv) to modify, eliminate or add to any provisions of the Pooling and Servicing Agreement to such extent as shall be necessary to maintain the qualification of any Trust REMIC as a REMIC or the Grantor Trust as a grantor trust under the relevant provisions of the Code at all times that any Certificate is outstanding, or to avoid or minimize the risk of imposition of any tax on the Trust or any Trust REMIC or the Grantor Trust; provided that the Trustee and the Certificate Administrator have received an Opinion of Counsel (at the expense of the party requesting such amendment) to the effect that (a) such action is necessary or desirable to maintain such qualification or to avoid or minimize the risk of the imposition of any such tax and (b) such action will not adversely affect in any material respect the interests of any Certificateholder (including, for the avoidance of doubt, any Holder of a VRR Interest, a Y&L Towers VRR Interest or a Standard Highline VRR Interest), or Companion Holder;

(v) to modify, eliminate or add to the provisions of Section 5.03(o) of the Pooling and Servicing Agreement or any other provision of the Pooling and Servicing Agreement restricting transfer of the Class R Certificates; provided the Depositor has determined that such change shall not, as evidenced by an Opinion of Counsel, cause the Trust, any Trust REMIC or

(vi) to revise or add any other provisions with respect to matters or questions arising under the Pooling and Servicing Agreement or any other change; provided that the required action shall not adversely affect in any material respect the interests of any Certificateholder (including, for the avoidance of doubt, any Holder of a VRR Interest, a Y&L Towers VRR Interest or a Standard Highline VRR Interest) or any holder of a Serviced Pari Passu Companion Loan not consenting to such revision or addition, as evidenced in writing by an Opinion of Counsel, at the expense of the party requesting such amendment or as evidenced by a Rating Agency Confirmation from each of the Rating Agencies with respect to such amendment or supplement and confirmation of the applicable rating agencies that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings of any class of Serviced Companion Loan Securities, if any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement);

(viii) to modify the provisions of Sections 3.05 and 3.17 of the Pooling and Servicing Agreement (with respect to reimbursement of Nonrecoverable Advances and Workout-Delayed Reimbursement Amounts) if (a) the Depositor, the Master Servicer, the Trustee and, for so long as a Control Termination Event has not occurred and is not continuing and, with respect to any Mortgage Loans other than any Excluded Loan, as to the Directing Holder or, in the case of the Directing Certificateholder, the Holder of a majority of the Controlling Class, the Directing Holder,

A-12-8

(ix) to modify the procedures of the Pooling and Servicing Agreement relating to compliance with Rule 17g-5 of the Exchange Act; provided that such amendment shall not adversely affect in any material respects the interests of any Certificateholders (including, for the avoidance of doubt, any Holders of a VRR Interest, a Y&L Towers VRR Interest or a Standard Highline VRR Interest), as evidenced by (x) an Opinion of Counsel or (y) if any Certificate is then rated, receipt of Rating Agency Confirmation from each Rating Agency rating such Certificates; and provided, further, that the Certificate Administrator shall give notice of any such amendment to the 17g-5 Information Provider for posting to the 17g-5 Information Provider’s Website pursuant to Section 3.13(c) of the Pooling and Servicing Agreement and the Certificate Administrator shall post such notice to the Certificate Administrator’s Website;

(x) to modify, eliminate or add to any provisions of the Pooling and Servicing Agreement to such extent as shall be necessary to comply with the requirements for use of Form SF-3 in registered offerings to the extent provided in CFR 239.45(b)(1)(ii), (iii) or (iv); or

(xi) to modify, eliminate or add to any of its provisions in the event the Credit Risk Retention Rules or any other regulations applicable to the risk retention requirements for this securitization transaction are amended or repealed, to the extent required to comply with any such amendment or to modify or eliminate the provision related to the risk retention requirements in the event of such repeal.

Notwithstanding the foregoing, no such amendment (A) may change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations of any Mortgage Loan Seller under any Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller or (B) may materially and adversely affect the holders of a Companion Loan without such Companion Holder’s consent.

A-12-9

The Pooling and Servicing Agreement may also be amended from time to time by the parties thereto with the consent of the Holders of Certificates of each Class affected by such amendment (including, for the avoidance of doubt, any Holders of the VRR Interest, the Y&L Towers VRR Interest or the Standard Highline VRR Interest to the extent any such amendment would adversely affect the rights of such Certificateholders) evidencing in the aggregate not less than a majority of the aggregate Percentage Interests constituting the Class for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of the Pooling and Servicing Agreement or of modifying in any manner the rights of the Holders of Certificates of such Class; provided, however, that no such amendment shall:

(i) reduce in any manner the amount of, or delay the timing of, payments received on the Mortgage Loans or the Trust Subordinate Companion Loans that are required to be distributed on a Certificate of any class without the consent of the Holder of the Certificate or which are required to be distributed to a Companion Holder without the consent of such Companion Holder; or

(ii) reduce the aforesaid percentage of Certificates of any Class the Holders of which are required to consent to any such amendment or remove the requirement to obtain consent of any Companion Holder or Holder of Loan-Specific Certificates, in any such case, without the consent of the Holders of all Certificates of such Class then-outstanding or such Companion Holders, as applicable; or

(iii) adversely affect the Voting Rights of any Class of Certificates without the consent of the Holders of all Certificates of such Class then outstanding; or

(iv) change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations of any Mortgage Loan Seller under such Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller; or

(v) amend the Servicing Standard without the consent of 100% of the Certificateholders or receipt of Rating Agency Confirmation from each Rating Agency and confirmation of the applicable rating agencies that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings of any Serviced Companion Loan Securities, if any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement) and, if required under the related Intercreditor Agreement, the consent of the holder of any AB Subordinate Companion Loan for each Serviced AB Whole Loan.

A-12-10

Notwithstanding the foregoing, none of the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Depositor, the Master Servicer nor the Special Servicer will be required to consent to any amendment to the Pooling and Servicing Agreement without having first received an Opinion of Counsel (at the Trust’s expense) to the effect that such amendment is permitted under the Pooling and Servicing Agreement, that all conditions precedent have been satisfied and that such amendment or the exercise of any power granted to the Master Servicer, the Special Servicer, the Depositor, the Trustee, the Certificate Administrator, the Operating Advisor, the Asset Representations Reviewer or any other specified person in accordance with such amendment will not result in the imposition of a tax on any portion of the Trust Fund or any Trust REMIC, or cause any Trust REMIC to fail to qualify as a REMIC or cause the Grantor Trust to fail to qualify as a grantor trust under the relevant provisions of the Code.

The Holders of the majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates may, in that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the Certificate Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage Loans (and all property acquired through exercise of remedies in respect of any related Mortgage Loan), the Trust Subordinate Companion Loans and the Trust’s portion of each REO Property remaining in the Trust Fund, and thereby effect termination of the Trust and early retirement of the then-outstanding Certificates, only on or after the first Distribution Date on which the aggregate Stated Principal Balances of the Mortgage Loans, the Trust Subordinate Companion Loans and the portion of any REO Loans held by the Trust is less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage Loans (solely for the purposes of this calculation, if such right is being exercised after December 2027 and the 237 East Fordham Road Mortgage Loan is still an asset of the Trust, then such Mortgage Loan will be excluded from the then-aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate Companion Loans and from the aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate Companion Loans as of the Cut-off Date) as set forth in the Pooling and Servicing Agreement.

Following the date on which the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class A-S, Class X-A, Class X-B, Class X-E, Class B and Class C Regular Interests have been reduced to zero (and provided that there is only one Holder (or multiple Holders acting in unanimity) of the then-outstanding Certificates (other than the Class Z and Class R Certificates)), the Sole Certificateholder shall have the right, with the consent of the Master Servicer, to exchange all of its Certificates (other than the Class Z and Class R Certificates) together with the payment or deemed payment of the Termination Purchase Amount for all of the Mortgage Loans, the Trust Subordinate Companion Loans and each REO Property remaining in the Trust Fund pursuant to the terms of the Pooling and Servicing Agreement.

The obligations created by the Pooling and Servicing Agreement and the Trust created thereby (other than the obligation of the Certificate Administrator to make payments to Certificateholders as provided for in the Pooling and Servicing Agreement), shall terminate upon reduction of the Certificate Balances of all the Certificates to zero (including, without limitation, any such final payment resulting from a termination of the Trust due to a sale of its property) pursuant to the terms of the Pooling and Servicing Agreement. In no event, however, will the

A-12-11

Trust created by the Pooling and Servicing Agreement continue beyond the expiration of 21 years from the death of the last survivor of the descendants of Joseph P. Kennedy, the late Ambassador of the United States to the Court of St. James, living on the date hereof.

Unless the certificate of authentication hereon has been executed by the Authenticating Agent, by manual signature, this Certificate shall not be entitled to any benefit under the Pooling and Servicing Agreement or be valid for any purpose. The Certificate Registrar has executed this Certificate on behalf of the Trust as Certificate Registrar under the Pooling and Servicing Agreement and makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates, the Mortgage Loans or the Trust Subordinate Companion Loans.

This certifies that [           ] is the registered owner of a beneficial ownership interest in a Trust Fund, including the distributions to be made with respect to the Class D Certificates. The Trust Fund, described more fully below, consists primarily of a pool of Mortgage Loans secured by first liens on commercial and multifamily properties and subordinate interests in two subordinate companion loans (the “Trust Subordinate Companion Loans”) held in trust by the Trustee and serviced by the Master Servicer. The Trust Fund was created, and the Mortgage Loans and the Trust Subordinate Companion Loans are to be serviced, pursuant to the Pooling and Servicing Agreement (as defined below). The Holder of this Certificate, by virtue of the acceptance hereof, assents to the terms, provisions and conditions of the Pooling and Servicing Agreement and is bound thereby. In the event that there is any conflict between any provision of this Certificate and any provision of the Pooling and Servicing Agreement, such provision of this Certificate shall be superseded to the extent of such inconsistency. Also issued under the Pooling and Servicing Agreement are the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class X-A, Class X-B, Class X-E, Class A-S, Class B, Class C, Class E, Class F, Class NR, Class V1-A, Class V1-B, Class V1-D, Class V1-E, Class V1-F, Class V1-Z, Class V2-A, Class V2-Z, Class UES-A, Class UES-B, Class UES-C, Class UES-D, Class UES-X, Class STN-A, Class STN-B, Class STN-X, Class STN-C, Class V1-UESA, Class V1-UESD, Class V2-UES, Class V1-STNA, Class V1-STNC, Class V2-STN, Class R and Class Z Certificates (together with the Class D Certificates, the “Certificates”; the Holders of Certificates are collectively referred to herein as “Certificateholders”).

This Certificate is issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of November 1, 2017 (the “Pooling and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities Corp., as Depositor, Wells Fargo Bank, National Association, as Certificate Administrator and as Trustee, Park Bridge Lender Services LLC, as Operating Advisor and as Asset Representations Reviewer, KeyBank National Association, as Master Servicer, and CWCapital Asset Management LLC, as Special Servicer. To the extent not defined herein, capitalized terms used herein shall have the meanings assigned thereto in the Pooling and Servicing Agreement.

This Certificate represents beneficial ownership of a “regular interest” in a “real estate mortgage investment conduit,” as those terms are defined, respectively, in Sections 860G(a)(1) and 860D of the Internal Revenue Code of 1986, as amended.

The Certificate Administrator makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates, the Mortgage Loans or the Trust Subordinate Companion Loans and has executed this Certificate in its limited capacity as Certificate Administrator under the Pooling and Servicing Agreement.

Pursuant to the terms of the Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution on any Certificate), on the 4th Business Day following the determination date of each month, commencing in December 2017 (each such date, a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related Record Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this Certificate) of that portion of the aggregate amount of principal and interest then distributable, if any, allocable to the Class D Certificates for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement. Holders of this Certificate

A-13-4

may be entitled to Yield Maintenance Charges, as provided in the Pooling and Servicing Agreement.

Interest accrued on this Certificate during an Interest Accrual Period, plus the aggregate unpaid Interest Shortfall with respect to this Certificate, if any, will be payable on the related Distribution Date to the extent provided in the Pooling and Servicing Agreement. The “Interest Accrual Period” with respect to any Distribution Date and with respect to the Class D Certificates is the calendar month immediately preceding the month in which such Distribution Date occurs and is assumed to consist of 30 days.

All distributions (other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons in whose names the Certificates are registered at the close of business on each Record Date, which will be the close of business on the last Business Day of the month immediately preceding the month in which such Distribution Date occurs. Distributions are required to be made (a) by wire transfer of immediately available funds to the account of such Certificateholder at a bank or other entity having appropriate facilities therefor, if such Certificateholder provided the Certificate Administrator with written wiring instructions no less than five Business Days prior to the related Record Date (which wiring instructions may be in the form of a standing order applicable to all subsequent Distribution Dates), or otherwise (b) by check mailed to such Certificateholder at its address in the Certificate Register. The final distribution on each Certificate will be made in like manner, but only upon presentment and surrender of such Certificate at the offices of the Certificate Registrar or such other location specified in the notice to Certificateholders of such final distribution.

Any funds not distributed to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure of such Certificateholders to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited to the account or accounts of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been given pursuant to Section 4.01(l) of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within six months after the time specified in such notice, the Certificate Administrator shall mail a second notice to the remaining non tendering Certificateholders to surrender their Certificates for cancellation in order to receive the final distribution with respect thereto. If within one year after the second notice all such Certificates shall not have been surrendered for cancellation, the Certificate Administrator, directly or through an agent, shall take such steps to contact the remaining non tendering Certificateholders concerning the surrender of their Certificates as it shall deem appropriate and subject to escheatment and other applicable laws. The costs and expenses of holding such funds in trust and of contacting such Certificateholders following the first anniversary of the delivery of such second notice to the non-tendering Certificateholders shall be paid out of such funds. No interest shall accrue or be payable to any Certificateholder on any amount held in trust under the Pooling and Servicing Agreement by the Certificate Administrator as a result of such Certificateholder’s failure to surrender its Certificate(s) for final payment thereof in accordance with Section 4.01(l) of the Pooling and Servicing Agreement.

This Certificate is limited in right of payment to, among other things, certain collections and recoveries in respect of the Mortgage Loans, as more specifically set forth herein and in the Pooling and Servicing Agreement.

A-13-5

As provided in the Pooling and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject to the Pooling and Servicing Agreement (including any Qualified Substitute Mortgage Loan replacing a removed Mortgage Loan) and the Trust Subordinate Companion Loans, together with the Mortgage Files relating thereto (subject to, in the case of a Serviced Whole Loan, the interests of the related Serviced Companion Noteholder in the related Mortgage File); (ii) all scheduled or unscheduled payments on or collections in respect of the Mortgage Loans and the Trust Subordinate Companion Loans due after the Cut-off Date (or with respect to a Qualified Substitute Mortgage Loan, the Due Date in the month of substitution); (iii) any REO Property (to the extent of the Trust’s interest therein) or the Trust’s beneficial interest in the Mortgaged Property securing a Non Serviced Whole Loan acquired under the related Non-Serviced PSA; (iv) all revenues received in respect of any REO Property (to the extent of the Trust’s interest therein); (v) the Master Servicer’s, the Special Servicer’s, the Certificate Administrator’s and the Trustee’s rights under the insurance policies with respect to the Mortgage Loans and the Trust Subordinate Companion Loans required to be maintained pursuant to the Pooling and Servicing Agreement and any proceeds thereof (to the extent of the Trust’s interest therein); (vi) any Assignment of Leases and any security agreements (to the extent of the Trust’s interest therein); (vii) any letters of credit, indemnities, guaranties or lease enhancement policies given as additional security for any related Mortgage Loans or Trust Subordinate Companion Loans (to the extent of the Trust’s interest therein); (viii) all assets deposited in the Loss of Value Reserve Fund and the Servicing Accounts (to the extent of the Trust’s interest therein), amounts on deposit in the Collection Account (to the extent of the Trust’s interest therein), the Lower-Tier REMIC Distribution Account, the Upper-Tier REMIC Distribution Account, the Trust Subordinate Companion Loan REMIC Distribution Accounts, the Regular Interest Distribution Account, the Excess Interest Distribution Account, the Interest Reserve Account, the Gain-on-Sale Reserve Account (to the extent of the Trust’s interest therein) and any REO Account (to the extent of the Trust’s interest therein), including any reinvestment income, as applicable; (ix) any Environmental Indemnity Agreements (to the extent of the Trust’s interest therein); (x) the rights and remedies of the Depositor under each Mortgage Loan Purchase Agreement (to the extent transferred to the Trustee); (xi) the Lower-Tier Regular Interests; (xii) the Trust Subordinate Companion Loan REMIC Regular Interests; and (xiii) the proceeds of the foregoing (other than any interest earned on deposits in the lock-box accounts, cash collateral accounts, escrow accounts and any reserve accounts, to the extent such interest belongs to the related Mortgagor).

This Certificate does not purport to summarize the Pooling and Servicing Agreement, and reference is made to the Pooling and Servicing Agreement for the interests, rights, benefits, obligations and duties evidenced hereby, and the limitations thereon, and the rights, duties and immunities of the Certificate Administrator and Trustee.

As provided in the Pooling and Servicing Agreement, subject to certain restrictions on transfer set forth therein, upon surrender for registration of transfer of any Certificate, the Certificate Administrator shall execute, authenticate and deliver, in the name of the designated transferee or transferees, one or more new Certificates in authorized denominations, in like aggregate interest and of the same Class.

Prior to due presentation of this Certificate for registration of transfer, the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee,

A-13-6

the Certificate Administrator, the Certificate Registrar, and any agent of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate Registrar may treat the Person in whose name any Certificate is registered as the owner of such Certificate for the purpose of receiving distributions as provided in the Pooling and Servicing Agreement and for all other purposes whatsoever, and none of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Certificate Registrar, or any agent of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate Registrar shall be affected by any notice to the contrary.

The Pooling and Servicing Agreement may be amended from time to time by the Depositor, the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Certificate Administrator and the Trustee, without the consent of any of the Certificateholders or the Companion Holders:

(i) to correct any defect or ambiguity in the Pooling and Servicing Agreement;

(iii) to change the timing and/or nature of deposits in the Collection Account, the Distribution Accounts or any REO Account; provided that (a) the P&I Advance Date shall in no event be later than the Business Day prior to the related Distribution Date and (b) such change shall not adversely affect in any material respect the interests of any Certificateholder (including, for the avoidance of doubt, any Holder of a VRR Interest, a Y&L Towers VRR Interest or a Standard Highline VRR Interest), as evidenced in writing by an Opinion of Counsel at the expense of the party requesting such amendment or as evidenced by a Rating Agency Confirmation from each Rating Agency with respect to such amendment;

(iv) to modify, eliminate or add to any provisions of the Pooling and Servicing Agreement to such extent as shall be necessary to maintain the qualification of any Trust REMIC as a REMIC or the Grantor Trust as a grantor trust under the relevant provisions of the Code at all times that any Certificate is outstanding, or to avoid or minimize the risk of imposition of any tax on the Trust or any Trust REMIC or the Grantor Trust; provided that the Trustee and the Certificate Administrator have received an Opinion of Counsel (at the expense of the party requesting such amendment) to the effect that (a) such action is necessary or desirable to maintain such qualification or to avoid or minimize the risk of the

A-13-7

imposition of any such tax and (b) such action will not adversely affect in any material respect the interests of any Certificateholder (including, for the avoidance of doubt, any Holder of a VRR Interest, a Y&L Towers VRR Interest or a Standard Highline VRR Interest), or Companion Holder;

(v) to modify, eliminate or add to the provisions of Section 5.03(o) of the Pooling and Servicing Agreement or any other provision of the Pooling and Servicing Agreement restricting transfer of the Class R Certificates; provided the Depositor has determined that such change shall not, as evidenced by an Opinion of Counsel, cause the Trust, any Trust REMIC or any of the Certificateholders (other than the Transferor) to be subject to a federal tax caused by a Transfer to a Person that is a Disqualified Organization or a Non-U.S. Tax Person;

(vi) to revise or add any other provisions with respect to matters or questions arising under the Pooling and Servicing Agreement or any other change; provided that the required action shall not adversely affect in any material respect the interests of any Certificateholder (including, for the avoidance of doubt, any Holder of a VRR Interest, a Y&L Towers VRR Interest or a Standard Highline VRR Interest) or any holder of a Serviced Pari Passu Companion Loan not consenting to such revision or addition, as evidenced in writing by an Opinion of Counsel, at the expense of the party requesting such amendment or as evidenced by a Rating Agency Confirmation from each of the Rating Agencies with respect to such amendment or supplement and confirmation of the applicable rating agencies that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings of any class of Serviced Companion Loan Securities, if any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement);

(vii) to amend or supplement any provision of the Pooling and Servicing Agreement to the extent necessary to maintain the then-current ratings assigned to each Class of Certificates by each Rating Agency, as evidenced by a Rating Agency Confirmation from each of the Rating Agencies and confirmation of the applicable rating agencies that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings of any class of Serviced Companion Loan Securities, if any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement); provided that such amendment or supplement shall not adversely affect in any material respect the interests of any Certificateholder (including, for the avoidance of doubt, any Holder of a VRR Interest, a Y&L Towers VRR Interest or a

A-13-8

Standard Highline VRR Interest) not consenting to such amendment or supplement, as evidenced by an Opinion of Counsel;

(viii) to modify the provisions of Sections 3.05 and 3.17 of the Pooling and Servicing Agreement (with respect to reimbursement of Nonrecoverable Advances and Workout-Delayed Reimbursement Amounts) if (a) the Depositor, the Master Servicer, the Trustee and, for so long as a Control Termination Event has not occurred and is not continuing and, with respect to any Mortgage Loans other than any Excluded Loan, as to the Directing Holder or, in the case of the Directing Certificateholder, the Holder of a majority of the Controlling Class, the Directing Holder, determine that the commercial mortgage backed securities industry standard for such provisions has changed, in order to conform to such industry standard, (b) such modification does not adversely affect the status of any Trust REMIC as a REMIC or the status of the Grantor Trust as a grantor trust under the relevant provisions of the Code, as evidenced by an Opinion of Counsel and (c) each Rating Agency has delivered a Rating Agency Confirmation and, with regard to any class of Serviced Companion Loan Securities, the applicable rating agencies have delivered a confirmation that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement);

(ix) to modify the procedures of the Pooling and Servicing Agreement relating to compliance with Rule 17g-5 of the Exchange Act; provided that such amendment shall not adversely affect in any material respects the interests of any Certificateholders (including, for the avoidance of doubt, any Holders of a VRR Interest, a Y&L Towers VRR Interest or a Standard Highline VRR Interest), as evidenced by (x) an Opinion of Counsel or (y) if any Certificate is then rated, receipt of Rating Agency Confirmation from each Rating Agency rating such Certificates; and provided, further, that the Certificate Administrator shall give notice of any such amendment to the 17g-5 Information Provider for posting to the 17g-5 Information Provider’s Website pursuant to Section 3.13(c) of the Pooling and Servicing Agreement and the Certificate Administrator shall post such notice to the Certificate Administrator’s Website;

(x) to modify, eliminate or add to any provisions of the Pooling and Servicing Agreement to such extent as shall be necessary to comply with the requirements for use of Form SF-3 in registered offerings to the extent provided in CFR 239.45(b)(1)(ii), (iii) or (iv); or

A-13-9

repealed, to the extent required to comply with any such amendment or to modify or eliminate the provision related to the risk retention requirements in the event of such repeal.

Notwithstanding the foregoing, no such amendment (A) may change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations of any Mortgage Loan Seller under any Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller or (B) may materially and adversely affect the holders of a Companion Loan without such Companion Holder’s consent.

The Pooling and Servicing Agreement may also be amended from time to time by the parties thereto with the consent of the Holders of Certificates of each Class affected by such amendment (including, for the avoidance of doubt, any Holders of the VRR Interest, the Y&L Towers VRR Interest or the Standard Highline VRR Interest to the extent any such amendment would adversely affect the rights of such Certificateholders) evidencing in the aggregate not less than a majority of the aggregate Percentage Interests constituting the Class for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of the Pooling and Servicing Agreement or of modifying in any manner the rights of the Holders of Certificates of such Class; provided, however, that no such amendment shall:

(i) reduce in any manner the amount of, or delay the timing of, payments received on the Mortgage Loans or the Trust Subordinate Companion Loans that are required to be distributed on a Certificate of any class without the consent of the Holder of the Certificate or which are required to be distributed to a Companion Holder without the consent of such Companion Holder; or

(ii) reduce the aforesaid percentage of Certificates of any Class the Holders of which are required to consent to any such amendment or remove the requirement to obtain consent of any Companion Holder or Holder of Loan-Specific Certificates, in any such case, without the consent of the Holders of all Certificates of such Class then-outstanding or such Companion Holders, as applicable; or

(iii) adversely affect the Voting Rights of any Class of Certificates without the consent of the Holders of all Certificates of such Class then outstanding; or

(iv) change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations of any Mortgage Loan Seller under such Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller; or

(v) amend the Servicing Standard without the consent of 100% of the

A-13-10

Certificateholders or receipt of Rating Agency Confirmation from each Rating Agency and confirmation of the applicable rating agencies that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings of any Serviced Companion Loan Securities, if any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement) and, if required under the related Intercreditor Agreement, the consent of the holder of any AB Subordinate Companion Loan for each Serviced AB Whole Loan.

Notwithstanding the foregoing, none of the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Depositor, the Master Servicer nor the Special Servicer will be required to consent to any amendment to the Pooling and Servicing Agreement without having first received an Opinion of Counsel (at the Trust’s expense) to the effect that such amendment is permitted under the Pooling and Servicing Agreement, that all conditions precedent have been satisfied and that such amendment or the exercise of any power granted to the Master Servicer, the Special Servicer, the Depositor, the Trustee, the Certificate Administrator, the Operating Advisor, the Asset Representations Reviewer or any other specified person in accordance with such amendment will not result in the imposition of a tax on any portion of the Trust Fund or any Trust REMIC, or cause any Trust REMIC to fail to qualify as a REMIC or cause the Grantor Trust to fail to qualify as a grantor trust under the relevant provisions of the Code.

The Holders of the majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates may, in that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the Certificate Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage Loans (and all property acquired through exercise of remedies in respect of any related Mortgage Loan), the Trust Subordinate Companion Loans and the Trust’s portion of each REO Property remaining in the Trust Fund, and thereby effect termination of the Trust and early retirement of the then-outstanding Certificates, only on or after the first Distribution Date on which the aggregate Stated Principal Balances of the Mortgage Loans, the Trust Subordinate Companion Loans and the portion of any REO Loans held by the Trust is less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage Loans (solely for the purposes of this calculation, if such right is being exercised after December 2027 and the 237 East Fordham Road Mortgage Loan is still an asset of the Trust, then such Mortgage Loan will be excluded from the then-aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate Companion Loans and from the aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate Companion Loans as of the Cut-off Date) as set forth in the Pooling and Servicing Agreement.

Following the date on which the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class A-S, Class X-A, Class X-B, Class X-E, Class B and Class C Regular Interests have been reduced to zero (and provided that there is only one Holder (or multiple Holders acting in unanimity) of the then-outstanding Certificates (other than the Class Z and Class R Certificates)), the Sole Certificateholder shall have the right, with the consent of the Master

A-13-11

Servicer, to exchange all of its Certificates (other than the Class Z and Class R Certificates) together with the payment or deemed payment of the Termination Purchase Amount for all of the Mortgage Loans, the Trust Subordinate Companion Loans and each REO Property remaining in the Trust Fund pursuant to the terms of the Pooling and Servicing Agreement.

The obligations created by the Pooling and Servicing Agreement and the Trust created thereby (other than the obligation of the Certificate Administrator to make payments to Certificateholders as provided for in the Pooling and Servicing Agreement), shall terminate upon reduction of the Certificate Balances of all the Certificates to zero (including, without limitation, any such final payment resulting from a termination of the Trust due to a sale of its property) pursuant to the terms of the Pooling and Servicing Agreement. In no event, however, will the Trust created by the Pooling and Servicing Agreement continue beyond the expiration of 21 years from the death of the last survivor of the descendants of Joseph P. Kennedy, the late Ambassador of the United States to the Court of St. James, living on the date hereof.

Unless the certificate of authentication hereon has been executed by the Authenticating Agent, by manual signature, this Certificate shall not be entitled to any benefit under the Pooling and Servicing Agreement or be valid for any purpose. The Certificate Registrar has executed this Certificate on behalf of the Trust as Certificate Registrar under the Pooling and Servicing Agreement and makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates, the Mortgage Loans or the Trust Subordinate Companion Loans.

This certifies that [           ] is the registered owner of a beneficial ownership interest in a Trust Fund, including the distributions to be made with respect to the Class E Certificates. The Trust Fund, described more fully below, consists primarily of a pool of Mortgage Loans secured by first liens on commercial and multifamily properties and subordinate interests in two subordinate companion loans (the “Trust Subordinate Companion Loans”) held in trust by the Trustee and serviced by the Master Servicer. The Trust Fund was created, and the Mortgage Loans and the Trust Subordinate Companion Loans are to be serviced, pursuant to the Pooling and Servicing Agreement (as defined below). The Holder of this Certificate, by virtue of the acceptance hereof, assents to the terms, provisions and conditions of the Pooling and Servicing Agreement and is bound thereby. In the event that there is any conflict between any provision of this Certificate and any provision of the Pooling and Servicing Agreement, such provision of this Certificate shall be superseded to the extent of such inconsistency. Also issued under the Pooling and Servicing Agreement are the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class X-A, Class X-B, Class X-E, Class A-S, Class B, Class C, Class D, Class F, Class NR, Class V1-A, Class V1-B, Class V1-D, Class V1-E, Class V1-F, Class V1-Z, Class V2-A, Class V2-Z, Class UES-A, Class UES-B, Class UES-C, Class UES-D, Class UES-X, Class STN-A, Class STN-B, Class STN-X, Class STN-C, Class V1-UESA, Class V1-UESD, Class V2-UES, Class V1-STNA, Class V1-STNC, Class V2-STN, Class R and Class Z Certificates (together with the Class E Certificates, the “Certificates”; the Holders of Certificates are collectively referred to herein as “Certificateholders”).

This Certificate is issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of November 1, 2017 (the “Pooling and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities Corp., as Depositor, Wells Fargo Bank, National Association, as Certificate Administrator and as Trustee, Park Bridge Lender Services LLC, as Operating Advisor and as Asset Representations Reviewer, KeyBank National Association, as Master Servicer, and CWCapital Asset Management LLC, as Special Servicer. To the extent not defined herein, capitalized terms used herein shall have the meanings assigned thereto in the Pooling and Servicing Agreement.

This Certificate represents beneficial ownership of a “regular interest” in a “real estate mortgage investment conduit,” as those terms are defined, respectively, in Sections 860G(a)(1) and 860D of the Internal Revenue Code of 1986, as amended.

The Certificate Administrator makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates, the Mortgage Loans or the Trust Subordinate Companion Loans and has executed this Certificate in its limited capacity as Certificate Administrator under the Pooling and Servicing Agreement.

Pursuant to the terms of the Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution on any Certificate), on the 4th Business Day following the determination date of each month, commencing in December 2017 (each such date, a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related Record Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this Certificate) of that portion of the aggregate amount of principal and interest then distributable, if any, allocable to the Class E Certificates for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement.

A-14-5

Interest accrued on this Certificate during an Interest Accrual Period, plus the aggregate unpaid Interest Shortfall with respect to this Certificate, if any, will be payable on the related Distribution Date to the extent provided in the Pooling and Servicing Agreement. The “Interest Accrual Period” with respect to any Distribution Date and with respect to the Class E Certificates is the calendar month immediately preceding the month in which such Distribution Date occurs and is assumed to consist of 30 days.

All distributions (other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons in whose names the Certificates are registered at the close of business on each Record Date, which will be the close of business on the last Business Day of the month immediately preceding the month in which such Distribution Date occurs. Distributions are required to be made (a) by wire transfer of immediately available funds to the account of such Certificateholder at a bank or other entity having appropriate facilities therefor, if such Certificateholder provided the Certificate Administrator with written wiring instructions no less than five Business Days prior to the related Record Date (which wiring instructions may be in the form of a standing order applicable to all subsequent Distribution Dates), or otherwise (b) by check mailed to such Certificateholder at its address in the Certificate Register. The final distribution on each Certificate will be made in like manner, but only upon presentment and surrender of such Certificate at the offices of the Certificate Registrar or such other location specified in the notice to Certificateholders of such final distribution.

Any funds not distributed to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure of such Certificateholders to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited to the account or accounts of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been given pursuant to Section 4.01(l) of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within six months after the time specified in such notice, the Certificate Administrator shall mail a second notice to the remaining non tendering Certificateholders to surrender their Certificates for cancellation in order to receive the final distribution with respect thereto. If within one year after the second notice all such Certificates shall not have been surrendered for cancellation, the Certificate Administrator, directly or through an agent, shall take such steps to contact the remaining non tendering Certificateholders concerning the surrender of their Certificates as it shall deem appropriate and subject to escheatment and other applicable laws. The costs and expenses of holding such funds in trust and of contacting such Certificateholders following the first anniversary of the delivery of such second notice to the non-tendering Certificateholders shall be paid out of such funds. No interest shall accrue or be payable to any Certificateholder on any amount held in trust under the Pooling and Servicing Agreement by the Certificate Administrator as a result of such Certificateholder’s failure to surrender its Certificate(s) for final payment thereof in accordance with Section 4.01(l) of the Pooling and Servicing Agreement.

This Certificate is limited in right of payment to, among other things, certain collections and recoveries in respect of the Mortgage Loans, as more specifically set forth herein and in the Pooling and Servicing Agreement.

As provided in the Pooling and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject to the Pooling and Servicing Agreement (including any Qualified Substitute Mortgage Loan replacing a removed Mortgage Loan) and the

A-14-6

Trust Subordinate Companion Loans, together with the Mortgage Files relating thereto (subject to, in the case of a Serviced Whole Loan, the interests of the related Serviced Companion Noteholder in the related Mortgage File); (ii) all scheduled or unscheduled payments on or collections in respect of the Mortgage Loans and the Trust Subordinate Companion Loans due after the Cut-off Date (or with respect to a Qualified Substitute Mortgage Loan, the Due Date in the month of substitution); (iii) any REO Property (to the extent of the Trust’s interest therein) or the Trust’s beneficial interest in the Mortgaged Property securing a Non Serviced Whole Loan acquired under the related Non-Serviced PSA; (iv) all revenues received in respect of any REO Property (to the extent of the Trust’s interest therein); (v) the Master Servicer’s, the Special Servicer’s, the Certificate Administrator’s and the Trustee’s rights under the insurance policies with respect to the Mortgage Loans and the Trust Subordinate Companion Loans required to be maintained pursuant to the Pooling and Servicing Agreement and any proceeds thereof (to the extent of the Trust’s interest therein); (vi) any Assignment of Leases and any security agreements (to the extent of the Trust’s interest therein); (vii) any letters of credit, indemnities, guaranties or lease enhancement policies given as additional security for any related Mortgage Loans or Trust Subordinate Companion Loans (to the extent of the Trust’s interest therein); (viii) all assets deposited in the Loss of Value Reserve Fund and the Servicing Accounts (to the extent of the Trust’s interest therein), amounts on deposit in the Collection Account (to the extent of the Trust’s interest therein), the Lower-Tier REMIC Distribution Account, the Upper-Tier REMIC Distribution Account, the Trust Subordinate Companion Loan REMIC Distribution Accounts, the Regular Interest Distribution Account, the Excess Interest Distribution Account, the Interest Reserve Account, the Gain-on-Sale Reserve Account (to the extent of the Trust’s interest therein) and any REO Account (to the extent of the Trust’s interest therein), including any reinvestment income, as applicable; (ix) any Environmental Indemnity Agreements (to the extent of the Trust’s interest therein); (x) the rights and remedies of the Depositor under each Mortgage Loan Purchase Agreement (to the extent transferred to the Trustee); (xi) the Lower-Tier Regular Interests; (xii) the Trust Subordinate Companion Loan REMIC Regular Interests; and (xiii) the proceeds of the foregoing (other than any interest earned on deposits in the lock-box accounts, cash collateral accounts, escrow accounts and any reserve accounts, to the extent such interest belongs to the related Mortgagor).

This Certificate does not purport to summarize the Pooling and Servicing Agreement, and reference is made to the Pooling and Servicing Agreement for the interests, rights, benefits, obligations and duties evidenced hereby, and the limitations thereon, and the rights, duties and immunities of the Certificate Administrator and Trustee.

As provided in the Pooling and Servicing Agreement, subject to certain restrictions on transfer set forth therein, upon surrender for registration of transfer of any Certificate, the Certificate Administrator shall execute, authenticate and deliver, in the name of the designated transferee or transferees, one or more new Certificates in authorized denominations, in like aggregate interest and of the same Class.

Prior to due presentation of this Certificate for registration of transfer, the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Certificate Registrar, and any agent of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate Registrar may treat the Person in whose name any

A-14-7

Certificate is registered as the owner of such Certificate for the purpose of receiving distributions as provided in the Pooling and Servicing Agreement and for all other purposes whatsoever, and none of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Certificate Registrar, or any agent of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate Registrar shall be affected by any notice to the contrary.

The Pooling and Servicing Agreement may be amended from time to time by the Depositor, the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Certificate Administrator and the Trustee, without the consent of any of the Certificateholders or the Companion Holders:

(i) to correct any defect or ambiguity in the Pooling and Servicing Agreement;

(iii) to change the timing and/or nature of deposits in the Collection Account, the Distribution Accounts or any REO Account; provided that (a) the P&I Advance Date shall in no event be later than the Business Day prior to the related Distribution Date and (b) such change shall not adversely affect in any material respect the interests of any Certificateholder (including, for the avoidance of doubt, any Holder of a VRR Interest, a Y&L Towers VRR Interest or a Standard Highline VRR Interest), as evidenced in writing by an Opinion of Counsel at the expense of the party requesting such amendment or as evidenced by a Rating Agency Confirmation from each Rating Agency with respect to such amendment;

(iv) to modify, eliminate or add to any provisions of the Pooling and Servicing Agreement to such extent as shall be necessary to maintain the qualification of any Trust REMIC as a REMIC or the Grantor Trust as a grantor trust under the relevant provisions of the Code at all times that any Certificate is outstanding, or to avoid or minimize the risk of imposition of any tax on the Trust or any Trust REMIC or the Grantor Trust; provided that the Trustee and the Certificate Administrator have received an Opinion of Counsel (at the expense of the party requesting such amendment) to the effect that (a) such action is necessary or desirable to maintain such qualification or to avoid or minimize the risk of the imposition of any such tax and (b) such action will not adversely affect in any material respect the interests of any Certificateholder (including, for the avoidance of doubt, any Holder of a VRR Interest, a Y&L Towers

A-14-9

(v) to modify, eliminate or add to the provisions of Section 5.03(o) of the Pooling and Servicing Agreement or any other provision of the Pooling and Servicing Agreement restricting transfer of the Class R Certificates; provided the Depositor has determined that such change shall not, as evidenced by an Opinion of Counsel, cause the Trust, any Trust REMIC or any of the Certificateholders (other than the Transferor) to be subject to a federal tax caused by a Transfer to a Person that is a Disqualified Organization or a Non-U.S. Tax Person;

(vi) to revise or add any other provisions with respect to matters or questions arising under the Pooling and Servicing Agreement or any other change; provided that the required action shall not adversely affect in any material respect the interests of any Certificateholder (including, for the avoidance of doubt, any Holder of a VRR Interest, a Y&L Towers VRR Interest or a Standard Highline VRR Interest) or any holder of a Serviced Pari Passu Companion Loan not consenting to such revision or addition, as evidenced in writing by an Opinion of Counsel, at the expense of the party requesting such amendment or as evidenced by a Rating Agency Confirmation from each of the Rating Agencies with respect to such amendment or supplement and confirmation of the applicable rating agencies that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings of any class of Serviced Companion Loan Securities, if any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement);

(vii) to amend or supplement any provision of the Pooling and Servicing Agreement to the extent necessary to maintain the then-current ratings assigned to each Class of Certificates by each Rating Agency, as evidenced by a Rating Agency Confirmation from each of the Rating Agencies and confirmation of the applicable rating agencies that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings of any class of Serviced Companion Loan Securities, if any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement); provided that such amendment or supplement shall not adversely affect in any material respect the interests of any Certificateholder (including, for the avoidance of doubt, any Holder of a VRR Interest, a Y&L Towers VRR Interest or a Standard Highline VRR Interest) not consenting to such amendment or supplement, as evidenced by an Opinion of Counsel;

(viii) to modify the provisions of Sections 3.05 and 3.17 of the Pooling and Servicing Agreement (with respect to reimbursement of Nonrecoverable Advances and Workout-Delayed Reimbursement Amounts) if (a) the

A-14-10

Depositor, the Master Servicer, the Trustee and, for so long as a Control Termination Event has not occurred and is not continuing and, with respect to any Mortgage Loans other than any Excluded Loan, as to the Directing Holder or, in the case of the Directing Certificateholder, the Holder of a majority of the Controlling Class, the Directing Holder, determine that the commercial mortgage backed securities industry standard for such provisions has changed, in order to conform to such industry standard, (b) such modification does not adversely affect the status of any Trust REMIC as a REMIC or the status of the Grantor Trust as a grantor trust under the relevant provisions of the Code, as evidenced by an Opinion of Counsel and (c) each Rating Agency has delivered a Rating Agency Confirmation and, with regard to any class of Serviced Companion Loan Securities, the applicable rating agencies have delivered a confirmation that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement);

(ix) to modify the procedures of the Pooling and Servicing Agreement relating to compliance with Rule 17g-5 of the Exchange Act; provided that such amendment shall not adversely affect in any material respects the interests of any Certificateholders (including, for the avoidance of doubt, any Holders of a VRR Interest, a Y&L Towers VRR Interest or a Standard Highline VRR Interest), as evidenced by (x) an Opinion of Counsel or (y) if any Certificate is then rated, receipt of Rating Agency Confirmation from each Rating Agency rating such Certificates; and provided, further, that the Certificate Administrator shall give notice of any such amendment to the 17g-5 Information Provider for posting to the 17g-5 Information Provider’s Website pursuant to Section 3.13(c) of the Pooling and Servicing Agreement and the Certificate Administrator shall post such notice to the Certificate Administrator’s Website;

(x) to modify, eliminate or add to any provisions of the Pooling and Servicing Agreement to such extent as shall be necessary to comply with the requirements for use of Form SF-3 in registered offerings to the extent provided in CFR 239.45(b)(1)(ii), (iii) or (iv); or

(xi) to modify, eliminate or add to any of its provisions in the event the Credit Risk Retention Rules or any other regulations applicable to the risk retention requirements for this securitization transaction are amended or repealed, to the extent required to comply with any such amendment or to modify or eliminate the provision related to the risk retention requirements in the event of such repeal.

Notwithstanding the foregoing, no such amendment (A) may change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations of any

A-14-11

Mortgage Loan Seller under any Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller or (B) may materially and adversely affect the holders of a Companion Loan without such Companion Holder’s consent.

The Pooling and Servicing Agreement may also be amended from time to time by the parties thereto with the consent of the Holders of Certificates of each Class affected by such amendment (including, for the avoidance of doubt, any Holders of the VRR Interest, the Y&L Towers VRR Interest or the Standard Highline VRR Interest to the extent any such amendment would adversely affect the rights of such Certificateholders) evidencing in the aggregate not less than a majority of the aggregate Percentage Interests constituting the Class for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of the Pooling and Servicing Agreement or of modifying in any manner the rights of the Holders of Certificates of such Class; provided, however, that no such amendment shall:

(i) reduce in any manner the amount of, or delay the timing of, payments received on the Mortgage Loans or the Trust Subordinate Companion Loans that are required to be distributed on a Certificate of any class without the consent of the Holder of the Certificate or which are required to be distributed to a Companion Holder without the consent of such Companion Holder; or

(ii) reduce the aforesaid percentage of Certificates of any Class the Holders of which are required to consent to any such amendment or remove the requirement to obtain consent of any Companion Holder or Holder of Loan-Specific Certificates, in any such case, without the consent of the Holders of all Certificates of such Class then-outstanding or such Companion Holders, as applicable; or

(iii) adversely affect the Voting Rights of any Class of Certificates without the consent of the Holders of all Certificates of such Class then outstanding; or

(iv) change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations of any Mortgage Loan Seller under such Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller; or

(v) amend the Servicing Standard without the consent of 100% of the Certificateholders or receipt of Rating Agency Confirmation from each Rating Agency and confirmation of the applicable rating agencies that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings of any Serviced Companion Loan Securities, if any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be

A-14-12

considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement) and, if required under the related Intercreditor Agreement, the consent of the holder of any AB Subordinate Companion Loan for each Serviced AB Whole Loan.

Notwithstanding the foregoing, none of the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Depositor, the Master Servicer nor the Special Servicer will be required to consent to any amendment to the Pooling and Servicing Agreement without having first received an Opinion of Counsel (at the Trust’s expense) to the effect that such amendment is permitted under the Pooling and Servicing Agreement, that all conditions precedent have been satisfied and that such amendment or the exercise of any power granted to the Master Servicer, the Special Servicer, the Depositor, the Trustee, the Certificate Administrator, the Operating Advisor, the Asset Representations Reviewer or any other specified person in accordance with such amendment will not result in the imposition of a tax on any portion of the Trust Fund or any Trust REMIC, or cause any Trust REMIC to fail to qualify as a REMIC or cause the Grantor Trust to fail to qualify as a grantor trust under the relevant provisions of the Code.

The Holders of the majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates may, in that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the Certificate Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage Loans (and all property acquired through exercise of remedies in respect of any related Mortgage Loan), the Trust Subordinate Companion Loans and the Trust’s portion of each REO Property remaining in the Trust Fund, and thereby effect termination of the Trust and early retirement of the then-outstanding Certificates, only on or after the first Distribution Date on which the aggregate Stated Principal Balances of the Mortgage Loans, the Trust Subordinate Companion Loans and the portion of any REO Loans held by the Trust is less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage Loans (solely for the purposes of this calculation, if such right is being exercised after December 2027 and the 237 East Fordham Road Mortgage Loan is still an asset of the Trust, then such Mortgage Loan will be excluded from the then-aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate Companion Loans and from the aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate Companion Loans as of the Cut-off Date) as set forth in the Pooling and Servicing Agreement.

Following the date on which the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class A-S, Class X-A, Class X-B, Class X-E, Class B and Class C Regular Interests have been reduced to zero (and provided that there is only one Holder (or multiple Holders acting in unanimity) of the then-outstanding Certificates (other than the Class Z and Class R Certificates)), the Sole Certificateholder shall have the right, with the consent of the Master Servicer, to exchange all of its Certificates (other than the Class Z and Class R Certificates) together with the payment or deemed payment of the Termination Purchase Amount for all of the Mortgage Loans, the Trust Subordinate Companion Loans and each REO Property remaining in the Trust Fund pursuant to the terms of the Pooling and Servicing Agreement.

The obligations created by the Pooling and Servicing Agreement and the Trust created thereby (other than the obligation of the Certificate Administrator to make payments to

A-14-13

Certificateholders as provided for in the Pooling and Servicing Agreement), shall terminate upon reduction of the Certificate Balances of all the Certificates to zero (including, without limitation, any such final payment resulting from a termination of the Trust due to a sale of its property) pursuant to the terms of the Pooling and Servicing Agreement. In no event, however, will the Trust created by the Pooling and Servicing Agreement continue beyond the expiration of 21 years from the death of the last survivor of the descendants of Joseph P. Kennedy, the late Ambassador of the United States to the Court of St. James, living on the date hereof.

Unless the certificate of authentication hereon has been executed by the Authenticating Agent, by manual signature, this Certificate shall not be entitled to any benefit under the Pooling and Servicing Agreement or be valid for any purpose. The Certificate Registrar has executed this Certificate on behalf of the Trust as Certificate Registrar under the Pooling and Servicing Agreement and makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates, the Mortgage Loans or the Trust Subordinate Companion Loans.

This certifies that [            ] is the registered owner of a beneficial ownership interest in a Trust Fund, including the distributions to be made with respect to the Class F Certificates. The Trust Fund, described more fully below, consists primarily of a pool of Mortgage Loans secured by first liens on commercial and multifamily properties and subordinate interests in two subordinate companion loans (the “Trust Subordinate Companion Loans”) held in trust by the Trustee and serviced by the Master Servicer. The Trust Fund was created, and the Mortgage Loans and the Trust Subordinate Companion Loans are to be serviced, pursuant to the Pooling and Servicing Agreement (as defined below). The Holder of this Certificate, by virtue of the acceptance hereof, assents to the terms, provisions and conditions of the Pooling and Servicing Agreement and is bound thereby. In the event that there is any conflict between any provision of this Certificate and any provision of the Pooling and Servicing Agreement, such provision of this Certificate shall be superseded to the extent of such inconsistency. Also issued under the Pooling and Servicing Agreement are the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class X-A, Class X-B, Class X-E, Class A-S, Class B, Class C, Class D, Class E, Class NR, Class V1-A, Class V1-B, Class V1-D, Class V1-E, Class V1-F, Class V1-Z, Class V2-A, Class V2-Z, Class UES-A, Class UES-B, Class UES-C, Class UES-D, Class UES-X, Class STN-A, Class STN-B, Class STN-X, Class STN-C, Class V1-UESA, Class V1-UESD, Class V2-UES, Class V1-STNA, Class V1-STNC, Class V2-STN, Class R and Class Z Certificates (together with the Class F Certificates, the “Certificates”; the Holders of Certificates are collectively referred to herein as “Certificateholders”).

This Certificate is issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of November 1, 2017 (the “Pooling and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities Corp., as Depositor, Wells Fargo Bank, National Association, as Certificate Administrator and as Trustee, Park Bridge Lender Services LLC, as Operating Advisor and as Asset Representations Reviewer, KeyBank National Association, as Master Servicer, and CWCapital Asset Management LLC, as Special Servicer. To the extent not defined herein, capitalized terms used herein shall have the meanings assigned thereto in the Pooling and Servicing Agreement.

This Certificate represents beneficial ownership of a “regular interest” in a “real estate mortgage investment conduit,” as those terms are defined, respectively, in Sections 860G(a)(1) and 860D of the Internal Revenue Code of 1986, as amended.

The Certificate Administrator makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates, the Mortgage Loans or the Trust Subordinate Companion Loans and has executed this Certificate in its limited capacity as Certificate Administrator under the Pooling and Servicing Agreement.

Pursuant to the terms of the Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution on any Certificate), on the 4th Business Day following the determination date of each month, commencing in December 2017 (each such date, a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related Record Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this Certificate) of that portion of the aggregate amount of principal and interest then distributable, if any, allocable to the Class F Certificates for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement.

A-15-5

Interest accrued on this Certificate during an Interest Accrual Period, plus the aggregate unpaid Interest Shortfall with respect to this Certificate, if any, will be payable on the related Distribution Date to the extent provided in the Pooling and Servicing Agreement. The “Interest Accrual Period” with respect to any Distribution Date and with respect to the Class F Certificates is the calendar month immediately preceding the month in which such Distribution Date occurs and is assumed to consist of 30 days.

All distributions (other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons in whose names the Certificates are registered at the close of business on each Record Date, which will be the close of business on the last Business Day of the month immediately preceding the month in which such Distribution Date occurs. Distributions are required to be made (a) by wire transfer of immediately available funds to the account of such Certificateholder at a bank or other entity having appropriate facilities therefor, if such Certificateholder provided the Certificate Administrator with written wiring instructions no less than five Business Days prior to the related Record Date (which wiring instructions may be in the form of a standing order applicable to all subsequent Distribution Dates), or otherwise (b) by check mailed to such Certificateholder at its address in the Certificate Register. The final distribution on each Certificate will be made in like manner, but only upon presentment and surrender of such Certificate at the offices of the Certificate Registrar or such other location specified in the notice to Certificateholders of such final distribution.

Any funds not distributed to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure of such Certificateholders to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited to the account or accounts of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been given pursuant to Section 4.01(l) of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within six months after the time specified in such notice, the Certificate Administrator shall mail a second notice to the remaining non tendering Certificateholders to surrender their Certificates for cancellation in order to receive the final distribution with respect thereto. If within one year after the second notice all such Certificates shall not have been surrendered for cancellation, the Certificate Administrator, directly or through an agent, shall take such steps to contact the remaining non tendering Certificateholders concerning the surrender of their Certificates as it shall deem appropriate and subject to escheatment and other applicable laws. The costs and expenses of holding such funds in trust and of contacting such Certificateholders following the first anniversary of the delivery of such second notice to the non-tendering Certificateholders shall be paid out of such funds. No interest shall accrue or be payable to any Certificateholder on any amount held in trust under the Pooling and Servicing Agreement by the Certificate Administrator as a result of such Certificateholder’s failure to surrender its Certificate(s) for final payment thereof in accordance with Section 4.01(l) of the Pooling and Servicing Agreement.

This Certificate is limited in right of payment to, among other things, certain collections and recoveries in respect of the Mortgage Loans, as more specifically set forth herein and in the Pooling and Servicing Agreement.

As provided in the Pooling and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject to the Pooling and Servicing Agreement (including any Qualified Substitute Mortgage Loan replacing a removed Mortgage Loan) and the

A-15-6

Trust Subordinate Companion Loans, together with the Mortgage Files relating thereto (subject to, in the case of a Serviced Whole Loan, the interests of the related Serviced Companion Noteholder in the related Mortgage File); (ii) all scheduled or unscheduled payments on or collections in respect of the Mortgage Loans and the Trust Subordinate Companion Loans due after the Cut-off Date (or with respect to a Qualified Substitute Mortgage Loan, the Due Date in the month of substitution); (iii) any REO Property (to the extent of the Trust’s interest therein) or the Trust’s beneficial interest in the Mortgaged Property securing a Non Serviced Whole Loan acquired under the related Non-Serviced PSA; (iv) all revenues received in respect of any REO Property (to the extent of the Trust’s interest therein); (v) the Master Servicer’s, the Special Servicer’s, the Certificate Administrator’s and the Trustee’s rights under the insurance policies with respect to the Mortgage Loans and the Trust Subordinate Companion Loans required to be maintained pursuant to the Pooling and Servicing Agreement and any proceeds thereof (to the extent of the Trust’s interest therein); (vi) any Assignment of Leases and any security agreements (to the extent of the Trust’s interest therein); (vii) any letters of credit, indemnities, guaranties or lease enhancement policies given as additional security for any related Mortgage Loans or Trust Subordinate Companion Loans (to the extent of the Trust’s interest therein); (viii) all assets deposited in the Loss of Value Reserve Fund and the Servicing Accounts (to the extent of the Trust’s interest therein), amounts on deposit in the Collection Account (to the extent of the Trust’s interest therein), the Lower-Tier REMIC Distribution Account, the Upper-Tier REMIC Distribution Account, the Trust Subordinate Companion Loan REMIC Distribution Accounts, the Regular Interest Distribution Account, the Excess Interest Distribution Account, the Interest Reserve Account, the Gain-on-Sale Reserve Account (to the extent of the Trust’s interest therein) and any REO Account (to the extent of the Trust’s interest therein), including any reinvestment income, as applicable; (ix) any Environmental Indemnity Agreements (to the extent of the Trust’s interest therein); (x) the rights and remedies of the Depositor under each Mortgage Loan Purchase Agreement (to the extent transferred to the Trustee); (xi) the Lower-Tier Regular Interests; (xii) the Trust Subordinate Companion Loan REMIC Regular Interests; and (xiii) the proceeds of the foregoing (other than any interest earned on deposits in the lock-box accounts, cash collateral accounts, escrow accounts and any reserve accounts, to the extent such interest belongs to the related Mortgagor).

This Certificate does not purport to summarize the Pooling and Servicing Agreement, and reference is made to the Pooling and Servicing Agreement for the interests, rights, benefits, obligations and duties evidenced hereby, and the limitations thereon, and the rights, duties and immunities of the Certificate Administrator and Trustee.

As provided in the Pooling and Servicing Agreement, subject to certain restrictions on transfer set forth therein, upon surrender for registration of transfer of any Certificate, the Certificate Administrator shall execute, authenticate and deliver, in the name of the designated transferee or transferees, one or more new Certificates in authorized denominations, in like aggregate interest and of the same Class.

Prior to due presentation of this Certificate for registration of transfer, the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Certificate Registrar, and any agent of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate Registrar may treat the Person in whose name any

A-15-7

Certificate is registered as the owner of such Certificate for the purpose of receiving distributions as provided in the Pooling and Servicing Agreement and for all other purposes whatsoever, and none of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Certificate Registrar, or any agent of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate Registrar shall be affected by any notice to the contrary.

The Pooling and Servicing Agreement may be amended from time to time by the Depositor, the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Certificate Administrator and the Trustee, without the consent of any of the Certificateholders or the Companion Holders:

(i) to correct any defect or ambiguity in the Pooling and Servicing Agreement;

(ii) to cause the provisions in the Pooling and Servicing Agreement to conform or be consistent with or in furtherance of the statements made in the Prospectus (or in an offering document for any related non-offered certificates) with respect to the Certificates, the Trust or the Pooling and Servicing Agreement or to correct or supplement any of its provisions which may be inconsistent with any other provisions therein or to correct any error;

(iii) to change the timing and/or nature of deposits in the Collection Account, the Distribution Accounts or any REO Account; provided that (a) the P&I Advance Date shall in no event be later than the Business Day prior to the related Distribution Date and (b) such change shall not adversely affect in any material respect the interests of any Certificateholder (including, for the avoidance of doubt, any Holder of a VRR Interest, a Y&L Towers VRR Interest or a Standard Highline VRR Interest), as evidenced in writing by an Opinion of Counsel at the expense of the party requesting such amendment or as evidenced by a Rating Agency Confirmation from each Rating Agency with respect to such amendment;

(iv) to modify, eliminate or add to any provisions of the Pooling and Servicing Agreement to such extent as shall be necessary to maintain the qualification of any Trust REMIC as a REMIC or the Grantor Trust as a grantor trust under the relevant provisions of the Code at all times that any Certificate is outstanding, or to avoid or minimize the risk of imposition of any tax on the Trust or any Trust REMIC or the Grantor Trust; provided that the Trustee and the Certificate Administrator have received an Opinion of Counsel (at the expense of the party requesting such amendment) to the effect that (a) such action is necessary or desirable to maintain such qualification or to avoid or minimize the risk of the imposition of any such tax and (b) such action will not adversely affect in any material respect the interests of any Certificateholder (including, for the avoidance of doubt, any Holder of a VRR Interest, a Y&L Towers

A-15-8

VRR Interest or a Standard Highline VRR Interest), or Companion Holder;

A-15-9

(v) to modify, eliminate or add to the provisions of Section 5.03(o) of the Pooling and Servicing Agreement or any other provision of the Pooling and Servicing Agreement restricting transfer of the Class R Certificates; provided the Depositor has determined that such change shall not, as evidenced by an Opinion of Counsel, cause the Trust, any Trust REMIC or any of the Certificateholders (other than the Transferor) to be subject to a federal tax caused by a Transfer to a Person that is a Disqualified Organization or a Non-U.S. Tax Person;

(vi) to revise or add any other provisions with respect to matters or questions arising under the Pooling and Servicing Agreement or any other change; provided that the required action shall not adversely affect in any material respect the interests of any Certificateholder (including, for the avoidance of doubt, any Holder of a VRR Interest, a Y&L Towers VRR Interest or a Standard Highline VRR Interest) or any holder of a Serviced Pari Passu Companion Loan not consenting to such revision or addition, as evidenced in writing by an Opinion of Counsel, at the expense of the party requesting such amendment or as evidenced by a Rating Agency Confirmation from each of the Rating Agencies with respect to such amendment or supplement and confirmation of the applicable rating agencies that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings of any class of Serviced Companion Loan Securities, if any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement);

(vii) to amend or supplement any provision of the Pooling and Servicing Agreement to the extent necessary to maintain the then-current ratings assigned to each Class of Certificates by each Rating Agency, as evidenced by a Rating Agency Confirmation from each of the Rating Agencies and confirmation of the applicable rating agencies that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings of any class of Serviced Companion Loan Securities, if any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement); provided that such amendment or supplement shall not adversely affect in any material respect the interests of any Certificateholder (including, for the avoidance of doubt, any Holder of a VRR Interest, a Y&L Towers VRR Interest or a Standard Highline VRR Interest) not consenting to such amendment or supplement, as evidenced by an Opinion of Counsel;

Depositor, the Master Servicer, the Trustee and, for so long as a Control Termination Event has not occurred and is not continuing and, with respect to any Mortgage Loans other than any Excluded Loan, as to the Directing Holder or, in the case of the Directing Certificateholder, the Holder of a majority of the Controlling Class, the Directing Holder, determine that the commercial mortgage backed securities industry standard for such provisions has changed, in order to conform to such industry standard, (b) such modification does not adversely affect the status of any Trust REMIC as a REMIC or the status of the Grantor Trust as a grantor trust under the relevant provisions of the Code, as evidenced by an Opinion of Counsel and (c) each Rating Agency has delivered a Rating Agency Confirmation and, with regard to any class of Serviced Companion Loan Securities, the applicable rating agencies have delivered a confirmation that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement);

(ix) to modify the procedures of the Pooling and Servicing Agreement relating to compliance with Rule 17g-5 of the Exchange Act; provided that such amendment shall not adversely affect in any material respects the interests of any Certificateholders (including, for the avoidance of doubt, any Holders of a VRR Interest, a Y&L Towers VRR Interest or a Standard Highline VRR Interest), as evidenced by (x) an Opinion of Counsel or (y) if any Certificate is then rated, receipt of Rating Agency Confirmation from each Rating Agency rating such Certificates; and provided, further, that the Certificate Administrator shall give notice of any such amendment to the 17g-5 Information Provider for posting to the 17g-5 Information Provider’s Website pursuant to Section 3.13(c) of the Pooling and Servicing Agreement and the Certificate Administrator shall post such notice to the Certificate Administrator’s Website;

(x) to modify, eliminate or add to any provisions of the Pooling and Servicing Agreement to such extent as shall be necessary to comply with the requirements for use of Form SF-3 in registered offerings to the extent provided in CFR 239.45(b)(1)(ii), (iii) or (iv); or

(xi) to modify, eliminate or add to any of its provisions in the event the Credit Risk Retention Rules or any other regulations applicable to the risk retention requirements for this securitization transaction are amended or repealed, to the extent required to comply with any such amendment or to modify or eliminate the provision related to the risk retention requirements in the event of such repeal.

Notwithstanding the foregoing, no such amendment (A) may change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations of any

A-15-11

Mortgage Loan Seller under any Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller or (B) may materially and adversely affect the holders of a Companion Loan without such Companion Holder’s consent.

The Pooling and Servicing Agreement may also be amended from time to time by the parties thereto with the consent of the Holders of Certificates of each Class affected by such amendment (including, for the avoidance of doubt, any Holders of the VRR Interest, the Y&L Towers VRR Interest or the Standard Highline VRR Interest to the extent any such amendment would adversely affect the rights of such Certificateholders) evidencing in the aggregate not less than a majority of the aggregate Percentage Interests constituting the Class for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of the Pooling and Servicing Agreement or of modifying in any manner the rights of the Holders of Certificates of such Class; provided, however, that no such amendment shall:

(i) reduce in any manner the amount of, or delay the timing of, payments received on the Mortgage Loans or the Trust Subordinate Companion Loans that are required to be distributed on a Certificate of any class without the consent of the Holder of the Certificate or which are required to be distributed to a Companion Holder without the consent of such Companion Holder; or

(ii) reduce the aforesaid percentage of Certificates of any Class the Holders of which are required to consent to any such amendment or remove the requirement to obtain consent of any Companion Holder or Holder of Loan-Specific Certificates, in any such case, without the consent of the Holders of all Certificates of such Class then-outstanding or such Companion Holders, as applicable; or

(iii) adversely affect the Voting Rights of any Class of Certificates without the consent of the Holders of all Certificates of such Class then outstanding; or

(iv) change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations of any Mortgage Loan Seller under such Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller; or

(v) amend the Servicing Standard without the consent of 100% of the Certificateholders or receipt of Rating Agency Confirmation from each Rating Agency and confirmation of the applicable rating agencies that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings of any Serviced Companion Loan Securities, if any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be

A-15-12

considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement) and, if required under the related Intercreditor Agreement, the consent of the holder of any AB Subordinate Companion Loan for each Serviced AB Whole Loan.

Notwithstanding the foregoing, none of the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Depositor, the Master Servicer nor the Special Servicer will be required to consent to any amendment to the Pooling and Servicing Agreement without having first received an Opinion of Counsel (at the Trust’s expense) to the effect that such amendment is permitted under the Pooling and Servicing Agreement, that all conditions precedent have been satisfied and that such amendment or the exercise of any power granted to the Master Servicer, the Special Servicer, the Depositor, the Trustee, the Certificate Administrator, the Operating Advisor, the Asset Representations Reviewer or any other specified person in accordance with such amendment will not result in the imposition of a tax on any portion of the Trust Fund or any Trust REMIC, or cause any Trust REMIC to fail to qualify as a REMIC or cause the Grantor Trust to fail to qualify as a grantor trust under the relevant provisions of the Code.

The Holders of the majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates may, in that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the Certificate Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage Loans (and all property acquired through exercise of remedies in respect of any related Mortgage Loan), the Trust Subordinate Companion Loans and the Trust’s portion of each REO Property remaining in the Trust Fund, and thereby effect termination of the Trust and early retirement of the then-outstanding Certificates, only on or after the first Distribution Date on which the aggregate Stated Principal Balances of the Mortgage Loans, the Trust Subordinate Companion Loans and the portion of any REO Loans held by the Trust is less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage Loans (solely for the purposes of this calculation, if such right is being exercised after December 2027 and the 237 East Fordham Road Mortgage Loan is still an asset of the Trust, then such Mortgage Loan will be excluded from the then-aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate Companion Loans and from the aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate Companion Loans as of the Cut-off Date) as set forth in the Pooling and Servicing Agreement.

Following the date on which the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class A-S, Class X-A, Class X-B, Class X-E, Class B and Class C Regular Interests have been reduced to zero (and provided that there is only one Holder (or multiple Holders acting in unanimity) of the then-outstanding Certificates (other than the Class Z and Class R Certificates)), the Sole Certificateholder shall have the right, with the consent of the Master Servicer, to exchange all of its Certificates (other than the Class Z and Class R Certificates) together with the payment or deemed payment of the Termination Purchase Amount for all of the Mortgage Loans, the Trust Subordinate Companion Loans and each REO Property remaining in the Trust Fund pursuant to the terms of the Pooling and Servicing Agreement.

The obligations created by the Pooling and Servicing Agreement and the Trust created thereby (other than the obligation of the Certificate Administrator to make payments to

A-15-13

Certificateholders as provided for in the Pooling and Servicing Agreement), shall terminate upon reduction of the Certificate Balances of all the Certificates to zero (including, without limitation, any such final payment resulting from a termination of the Trust due to a sale of its property) pursuant to the terms of the Pooling and Servicing Agreement. In no event, however, will the Trust created by the Pooling and Servicing Agreement continue beyond the expiration of 21 years from the death of the last survivor of the descendants of Joseph P. Kennedy, the late Ambassador of the United States to the Court of St. James, living on the date hereof.

Unless the certificate of authentication hereon has been executed by the Authenticating Agent, by manual signature, this Certificate shall not be entitled to any benefit under the Pooling and Servicing Agreement or be valid for any purpose. The Certificate Registrar has executed this Certificate on behalf of the Trust as Certificate Registrar under the Pooling and Servicing Agreement and makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates, the Mortgage Loans or the Trust Subordinate Companion Loans.

This certifies that [           ] is the registered owner of a beneficial ownership interest in a Trust Fund, including the distributions to be made with respect to the Class NR Certificates. The Trust Fund, described more fully below, consists primarily of a pool of Mortgage Loans secured by first liens on commercial and multifamily properties and subordinate interests in two subordinate companion loans (the “Trust Subordinate Companion Loans”) held in trust by the Trustee and serviced by the Master Servicer. The Trust Fund was created, and the Mortgage Loans and the Trust Subordinate Companion Loans are to be serviced, pursuant to the Pooling and Servicing Agreement (as defined below). The Holder of this Certificate, by virtue of the acceptance hereof, assents to the terms, provisions and conditions of the Pooling and Servicing Agreement and is bound thereby. In the event that there is any conflict between any provision of this Certificate and any provision of the Pooling and Servicing Agreement, such provision of this Certificate shall be superseded to the extent of such inconsistency. Also issued under the Pooling and Servicing Agreement are the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class X-A, Class X-B, Class X-E, Class A-S, Class B, Class C, Class D, Class E, Class F, Class V1-A, Class V1-B, Class V1-D, Class V1-E, Class V1-F, Class V1-Z, Class V2-A, Class V2-Z, Class UES-A, Class UES-B, Class UES-C, Class UES-D, Class UES-X, Class STN-A, Class STN-B, Class STN-X, Class STN-C, Class V1-UESA, Class V1-UESD, Class V2-UES, Class V1-STNA, Class V1-STNC, Class V2-STN, Class R and Class Z Certificates (together with the Class NR Certificates, the “Certificates”; the Holders of Certificates are collectively referred to herein as “Certificateholders”).

This Certificate is issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of November 1, 2017 (the “Pooling and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities Corp., as Depositor, Wells Fargo Bank, National Association, as Certificate Administrator and as Trustee, Park Bridge Lender Services LLC, as Operating Advisor and as Asset Representations Reviewer, KeyBank National Association, as Master Servicer, and CWCapital Asset Management LLC, as Special Servicer. To the extent not defined herein, capitalized terms used herein shall have the meanings assigned thereto in the Pooling and Servicing Agreement.

This Certificate represents beneficial ownership of a “regular interest” in a “real estate mortgage investment conduit,” as those terms are defined, respectively, in Sections 860G(a)(1) and 860D of the Internal Revenue Code of 1986, as amended.

The Certificate Administrator makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates, the Mortgage Loans or the Trust Subordinate Companion Loans and has executed this Certificate in its limited capacity as Certificate Administrator under the Pooling and Servicing Agreement.

Pursuant to the terms of the Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution on any Certificate), on the 4th Business Day following the determination date of each month, commencing in December 2017 (each such date, a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related Record Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this Certificate) of that portion of the aggregate amount of principal and interest then distributable, if any, allocable to the Class NR Certificates for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement.

A-16-5

Interest accrued on this Certificate during an Interest Accrual Period, plus the aggregate unpaid Interest Shortfall with respect to this Certificate, if any, will be payable on the related Distribution Date to the extent provided in the Pooling and Servicing Agreement. The “Interest Accrual Period” with respect to any Distribution Date and with respect to the Class NR Certificates is the calendar month immediately preceding the month in which such Distribution Date occurs and is assumed to consist of 30 days.

All distributions (other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons in whose names the Certificates are registered at the close of business on each Record Date, which will be the close of business on the last Business Day of the month immediately preceding the month in which such Distribution Date occurs. Distributions are required to be made (a) by wire transfer of immediately available funds to the account of such Certificateholder at a bank or other entity having appropriate facilities therefor, if such Certificateholder provided the Certificate Administrator with written wiring instructions no less than five Business Days prior to the related Record Date (which wiring instructions may be in the form of a standing order applicable to all subsequent Distribution Dates), or otherwise (b) by check mailed to such Certificateholder at its address in the Certificate Register. The final distribution on each Certificate will be made in like manner, but only upon presentment and surrender of such Certificate at the offices of the Certificate Registrar or such other location specified in the notice to Certificateholders of such final distribution.

Any funds not distributed to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure of such Certificateholders to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited to the account or accounts of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been given pursuant to Section 4.01(l) of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within six months after the time specified in such notice, the Certificate Administrator shall mail a second notice to the remaining non tendering Certificateholders to surrender their Certificates for cancellation in order to receive the final distribution with respect thereto. If within one year after the second notice all such Certificates shall not have been surrendered for cancellation, the Certificate Administrator, directly or through an agent, shall take such steps to contact the remaining non tendering Certificateholders concerning the surrender of their Certificates as it shall deem appropriate and subject to escheatment and other applicable laws. The costs and expenses of holding such funds in trust and of contacting such Certificateholders following the first anniversary of the delivery of such second notice to the non-tendering Certificateholders shall be paid out of such funds. No interest shall accrue or be payable to any Certificateholder on any amount held in trust under the Pooling and Servicing Agreement by the Certificate Administrator as a result of such Certificateholder’s failure to surrender its Certificate(s) for final payment thereof in accordance with Section 4.01(l) of the Pooling and Servicing Agreement.

This Certificate is limited in right of payment to, among other things, certain collections and recoveries in respect of the Mortgage Loans, as more specifically set forth herein and in the Pooling and Servicing Agreement.

As provided in the Pooling and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject to the Pooling and Servicing Agreement (including any Qualified Substitute Mortgage Loan replacing a removed Mortgage Loan) and the

A-16-6

Trust Subordinate Companion Loans, together with the Mortgage Files relating thereto (subject to, in the case of a Serviced Whole Loan, the interests of the related Serviced Companion Noteholder in the related Mortgage File); (ii) all scheduled or unscheduled payments on or collections in respect of the Mortgage Loans and the Trust Subordinate Companion Loans due after the Cut-off Date (or with respect to a Qualified Substitute Mortgage Loan, the Due Date in the month of substitution); (iii) any REO Property (to the extent of the Trust’s interest therein) or the Trust’s beneficial interest in the Mortgaged Property securing a Non Serviced Whole Loan acquired under the related Non-Serviced PSA; (iv) all revenues received in respect of any REO Property (to the extent of the Trust’s interest therein); (v) the Master Servicer’s, the Special Servicer’s, the Certificate Administrator’s and the Trustee’s rights under the insurance policies with respect to the Mortgage Loans and the Trust Subordinate Companion Loans required to be maintained pursuant to the Pooling and Servicing Agreement and any proceeds thereof (to the extent of the Trust’s interest therein); (vi) any Assignment of Leases and any security agreements (to the extent of the Trust’s interest therein); (vii) any letters of credit, indemnities, guaranties or lease enhancement policies given as additional security for any related Mortgage Loans or Trust Subordinate Companion Loans (to the extent of the Trust’s interest therein); (viii) all assets deposited in the Loss of Value Reserve Fund and the Servicing Accounts (to the extent of the Trust’s interest therein), amounts on deposit in the Collection Account (to the extent of the Trust’s interest therein), the Lower-Tier REMIC Distribution Account, the Upper-Tier REMIC Distribution Account, the Trust Subordinate Companion Loan REMIC Distribution Accounts, the Regular Interest Distribution Account, the Excess Interest Distribution Account, the Interest Reserve Account, the Gain-on-Sale Reserve Account (to the extent of the Trust’s interest therein) and any REO Account (to the extent of the Trust’s interest therein), including any reinvestment income, as applicable; (ix) any Environmental Indemnity Agreements (to the extent of the Trust’s interest therein); (x) the rights and remedies of the Depositor under each Mortgage Loan Purchase Agreement (to the extent transferred to the Trustee); (xi) the Lower-Tier Regular Interests; (xii) the Trust Subordinate Companion Loan REMIC Regular Interests; and (xiii) the proceeds of the foregoing (other than any interest earned on deposits in the lock-box accounts, cash collateral accounts, escrow accounts and any reserve accounts, to the extent such interest belongs to the related Mortgagor).

This Certificate does not purport to summarize the Pooling and Servicing Agreement, and reference is made to the Pooling and Servicing Agreement for the interests, rights, benefits, obligations and duties evidenced hereby, and the limitations thereon, and the rights, duties and immunities of the Certificate Administrator and Trustee.

As provided in the Pooling and Servicing Agreement, subject to certain restrictions on transfer set forth therein, upon surrender for registration of transfer of any Certificate, the Certificate Administrator shall execute, authenticate and deliver, in the name of the designated transferee or transferees, one or more new Certificates in authorized denominations, in like aggregate interest and of the same Class.

Prior to due presentation of this Certificate for registration of transfer, the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Certificate Registrar, and any agent of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate Registrar may treat the Person in whose name any

A-16-7

Certificate is registered as the owner of such Certificate for the purpose of receiving distributions as provided in the Pooling and Servicing Agreement and for all other purposes whatsoever, and none of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Certificate Registrar, or any agent of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate Registrar shall be affected by any notice to the contrary.

The Pooling and Servicing Agreement may be amended from time to time by the Depositor, the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Certificate Administrator and the Trustee, without the consent of any of the Certificateholders or the Companion Holders:

(i) to correct any defect or ambiguity in the Pooling and Servicing Agreement;

(ix) to modify the procedures of the Pooling and Servicing Agreement relating to compliance with Rule 17g-5 of the Exchange Act; provided that such amendment shall not adversely affect in any material respects the interests of any Certificateholders (including, for the avoidance of doubt, any Holders of a VRR Interest, a Y&L Towers VRR Interest or a Standard Highline VRR Interest), as evidenced by (x) an Opinion of Counsel or (y) if any Certificate is then rated, receipt of Rating Agency Confirmation from each Rating Agency rating such Certificates; and provided, further, that the Certificate Administrator shall give notice of any such amendment to the 17g-5 Information Provider for posting to the 17g-5 Information Provider’s Website pursuant to Section 3.13(c) of the Pooling and Servicing Agreement and the Certificate Administrator shall post such notice to the Certificate Administrator’s Website;

(x) to modify, eliminate or add to any provisions of the Pooling and Servicing Agreement to such extent as shall be necessary to comply with the requirements for use of Form SF-3 in registered offerings to the extent provided in CFR 239.45(b)(1)(ii), (iii) or (iv); or

(xi) to modify, eliminate or add to any of its provisions in the event the Credit Risk Retention Rules or any other regulations applicable to the risk retention requirements for this securitization transaction are amended or repealed, to the extent required to comply with any such amendment or to modify or eliminate the provision related to the risk retention requirements in the event of such repeal.

Notwithstanding the foregoing, no such amendment (A) may change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations of any

A-16-11

Mortgage Loan Seller under any Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller or (B) may materially and adversely affect the holders of a Companion Loan without such Companion Holder’s consent.

The Pooling and Servicing Agreement may also be amended from time to time by the parties thereto with the consent of the Holders of Certificates of each Class affected by such amendment (including, for the avoidance of doubt, any Holders of the VRR Interest, the Y&L Towers VRR Interest or the Standard Highline VRR Interest to the extent any such amendment would adversely affect the rights of such Certificateholders) evidencing in the aggregate not less than a majority of the aggregate Percentage Interests constituting the Class for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of the Pooling and Servicing Agreement or of modifying in any manner the rights of the Holders of Certificates of such Class; provided, however, that no such amendment shall:

(i) reduce in any manner the amount of, or delay the timing of, payments received on the Mortgage Loans or the Trust Subordinate Companion Loans that are required to be distributed on a Certificate of any class without the consent of the Holder of the Certificate or which are required to be distributed to a Companion Holder without the consent of such Companion Holder; or

(ii) reduce the aforesaid percentage of Certificates of any Class the Holders of which are required to consent to any such amendment or remove the requirement to obtain consent of any Companion Holder or Holder of Loan-Specific Certificates, in any such case, without the consent of the Holders of all Certificates of such Class then-outstanding or such Companion Holders, as applicable; or

(iii) adversely affect the Voting Rights of any Class of Certificates without the consent of the Holders of all Certificates of such Class then outstanding; or

(iv) change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations of any Mortgage Loan Seller under such Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller; or

(v) amend the Servicing Standard without the consent of 100% of the Certificateholders or receipt of Rating Agency Confirmation from each Rating Agency and confirmation of the applicable rating agencies that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings of any Serviced Companion Loan Securities, if any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be

A-16-12

considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement) and, if required under the related Intercreditor Agreement, the consent of the holder of any AB Subordinate Companion Loan for each Serviced AB Whole Loan.

Notwithstanding the foregoing, none of the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Depositor, the Master Servicer nor the Special Servicer will be required to consent to any amendment to the Pooling and Servicing Agreement without having first received an Opinion of Counsel (at the Trust’s expense) to the effect that such amendment is permitted under the Pooling and Servicing Agreement, that all conditions precedent have been satisfied and that such amendment or the exercise of any power granted to the Master Servicer, the Special Servicer, the Depositor, the Trustee, the Certificate Administrator, the Operating Advisor, the Asset Representations Reviewer or any other specified person in accordance with such amendment will not result in the imposition of a tax on any portion of the Trust Fund or any Trust REMIC, or cause any Trust REMIC to fail to qualify as a REMIC or cause the Grantor Trust to fail to qualify as a grantor trust under the relevant provisions of the Code.

The Holders of the majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates may, in that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the Certificate Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage Loans (and all property acquired through exercise of remedies in respect of any related Mortgage Loan), the Trust Subordinate Companion Loans and the Trust’s portion of each REO Property remaining in the Trust Fund, and thereby effect termination of the Trust and early retirement of the then-outstanding Certificates, only on or after the first Distribution Date on which the aggregate Stated Principal Balances of the Mortgage Loans, the Trust Subordinate Companion Loans and the portion of any REO Loans held by the Trust is less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage Loans (solely for the purposes of this calculation, if such right is being exercised after December 2027 and the 237 East Fordham Road Mortgage Loan is still an asset of the Trust, then such Mortgage Loan will be excluded from the then-aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate Companion Loans and from the aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate Companion Loans as of the Cut-off Date) as set forth in the Pooling and Servicing Agreement.

Following the date on which the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class A-S, Class X-A, Class X-B, Class X-E, Class B and Class C Regular Interests have been reduced to zero (and provided that there is only one Holder (or multiple Holders acting in unanimity) of the then-outstanding Certificates (other than the Class Z and Class R Certificates)), the Sole Certificateholder shall have the right, with the consent of the Master Servicer, to exchange all of its Certificates (other than the Class Z and Class R Certificates) together with the payment or deemed payment of the Termination Purchase Amount for all of the Mortgage Loans, the Trust Subordinate Companion Loans and each REO Property remaining in the Trust Fund pursuant to the terms of the Pooling and Servicing Agreement.

The obligations created by the Pooling and Servicing Agreement and the Trust created thereby (other than the obligation of the Certificate Administrator to make payments to

A-16-13

Certificateholders as provided for in the Pooling and Servicing Agreement), shall terminate upon reduction of the Certificate Balances of all the Certificates to zero (including, without limitation, any such final payment resulting from a termination of the Trust due to a sale of its property) pursuant to the terms of the Pooling and Servicing Agreement. In no event, however, will the Trust created by the Pooling and Servicing Agreement continue beyond the expiration of 21 years from the death of the last survivor of the descendants of Joseph P. Kennedy, the late Ambassador of the United States to the Court of St. James, living on the date hereof.

Unless the certificate of authentication hereon has been executed by the Authenticating Agent, by manual signature, this Certificate shall not be entitled to any benefit under the Pooling and Servicing Agreement or be valid for any purpose. The Certificate Registrar has executed this Certificate on behalf of the Trust as Certificate Registrar under the Pooling and Servicing Agreement and makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates, the Mortgage Loans or the Trust Subordinate Companion Loans.

This Certificate is issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of November 1, 2017 (the “Pooling and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities Corp., as Depositor, Wells Fargo Bank, National Association, as Certificate Administrator and as Trustee, Park Bridge Lender Services LLC, as Operating Advisor and as Asset Representations Reviewer, KeyBank National Association, as Master Servicer, and CWCapital Asset Management LLC, as Special Servicer. To the extent not defined herein, capitalized terms used herein shall have the meanings assigned thereto in the Pooling and Servicing Agreement.

This Certificate represents a “residual interest” in four “real estate mortgage investment conduits,” as those terms are defined, respectively, in Sections 860G(a)(2) and 860D of the Internal Revenue Code of 1986, as amended.

Each Holder of this Certificate, by acceptance hereof, agrees to treat, and take no action inconsistent with the treatment of, this Certificate in accordance with the preceding sentence for purposes of federal income taxes, state and local income and franchise taxes and other taxes imposed on or measured by income. The Holder of the largest Percentage Interest in the Class R Certificates shall be the “tax matters person” pursuant to Treasury Regulations Section 1.860F 4(d) and “partnership representative” (within the meaning of Section 6223 of the Code, to the extent such provision is applicable to the Trust REMICs) for each Trust REMIC, and the Certificate Administrator is hereby irrevocably designated and shall serve as attorney in fact and agent for any such Person that is the “tax matters person” or “partnership representative”.

The Certificate Administrator makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates, the Mortgage Loans or the Trust Subordinate Companion Loans and has executed this Certificate in its limited capacity as Certificate Administrator under the Pooling and Servicing Agreement.

Pursuant to the terms of the Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution on any Certificate), on the 4th Business Day following the determination date of each month, commencing in December 2017 (each such date, a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related Record Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this Certificate) of the aggregate amount, if any, allocable to the Class R

A-18-4

Certificates for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement.

All distributions (other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons in whose names the Certificates are registered at the close of business on each Record Date, which will be the close of business on the last Business Day of the month immediately preceding the month in which such Distribution Date occurs. Distributions are required to be made (a) by wire transfer of immediately available funds to the account of such Certificateholder at a bank or other entity having appropriate facilities therefor, if such Certificateholder provided the Certificate Administrator with written wiring instructions no less than five Business Days prior to the related Record Date (which wiring instructions may be in the form of a standing order applicable to all subsequent Distribution Dates), or otherwise (b) by check mailed to such Certificateholder at its address in the Certificate Register. The final distribution on each Certificate will be made in like manner, but only upon presentment and surrender of such Certificate at the offices of the Certificate Registrar or such other location specified in the notice to Certificateholders of such final distribution.

Any funds not distributed to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure of such Certificateholders to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited to the account or accounts of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been given pursuant to Section 4.01(l) of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within six months after the time specified in such notice, the Certificate Administrator shall mail a second notice to the remaining non tendering Certificateholders to surrender their Certificates for cancellation in order to receive the final distribution with respect thereto. If within one year after the second notice all such Certificates shall not have been surrendered for cancellation, the Certificate Administrator, directly or through an agent, shall take such steps to contact the remaining non tendering Certificateholders concerning the surrender of their Certificates as it shall deem appropriate and subject to escheatment and other applicable laws. The costs and expenses of holding such funds in trust and of contacting such Certificateholders following the first anniversary of the delivery of such second notice to the non-tendering Certificateholders shall be paid out of such funds. No interest shall accrue or be payable to any Certificateholder on any amount held in trust under the Pooling and Servicing Agreement by the Certificate Administrator as a result of such Certificateholder’s failure to surrender its Certificate(s) for final payment thereof in accordance with Section 4.01(l) of the Pooling and Servicing Agreement.

This Certificate is limited in right of payment to, among other things, certain collections and recoveries in respect of the Mortgage Loans, as more specifically set forth herein and in the Pooling and Servicing Agreement.

As provided in the Pooling and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject to the Pooling and Servicing Agreement (including any Qualified Substitute Mortgage Loan replacing a removed Mortgage Loan) and the Trust Subordinate Companion Loans, together with the Mortgage Files relating thereto (subject to, in the case of a Serviced Whole Loan, the interests of the related Serviced Companion Noteholder in the related Mortgage File); (ii) all scheduled or unscheduled payments on or collections in respect of the Mortgage Loans and the Trust Subordinate Companion Loans due

A-18-5

after the Cut-off Date (or with respect to a Qualified Substitute Mortgage Loan, the Due Date in the month of substitution); (iii) any REO Property (to the extent of the Trust’s interest therein) or the Trust’s beneficial interest in the Mortgaged Property securing a Non Serviced Whole Loan acquired under the related Non-Serviced PSA; (iv) all revenues received in respect of any REO Property (to the extent of the Trust’s interest therein); (v) the Master Servicer’s, the Special Servicer’s, the Certificate Administrator’s and the Trustee’s rights under the insurance policies with respect to the Mortgage Loans and the Trust Subordinate Companion Loans required to be maintained pursuant to the Pooling and Servicing Agreement and any proceeds thereof (to the extent of the Trust’s interest therein); (vi) any Assignment of Leases and any security agreements (to the extent of the Trust’s interest therein); (vii) any letters of credit, indemnities, guaranties or lease enhancement policies given as additional security for any related Mortgage Loans or Trust Subordinate Companion Loans (to the extent of the Trust’s interest therein); (viii) all assets deposited in the Loss of Value Reserve Fund and the Servicing Accounts (to the extent of the Trust’s interest therein), amounts on deposit in the Collection Account (to the extent of the Trust’s interest therein), the Lower-Tier REMIC Distribution Account, the Upper-Tier REMIC Distribution Account, the Trust Subordinate Companion Loan REMIC Distribution Accounts, the Regular Interest Distribution Account, the Excess Interest Distribution Account, the Interest Reserve Account, the Gain-on-Sale Reserve Account (to the extent of the Trust’s interest therein) and any REO Account (to the extent of the Trust’s interest therein), including any reinvestment income, as applicable; (ix) any Environmental Indemnity Agreements (to the extent of the Trust’s interest therein); (x) the rights and remedies of the Depositor under each Mortgage Loan Purchase Agreement (to the extent transferred to the Trustee); (xi) the Lower-Tier Regular Interests; (xii) the Trust Subordinate Companion Loan REMIC Regular Interests; and (xiii) the proceeds of the foregoing (other than any interest earned on deposits in the lock-box accounts, cash collateral accounts, escrow accounts and any reserve accounts, to the extent such interest belongs to the related Mortgagor).

This Certificate does not purport to summarize the Pooling and Servicing Agreement, and reference is made to the Pooling and Servicing Agreement for the interests, rights, benefits, obligations and duties evidenced hereby, and the limitations thereon, and the rights, duties and immunities of the Certificate Administrator and Trustee.

As provided in the Pooling and Servicing Agreement, subject to certain restrictions on transfer set forth therein, upon surrender for registration of transfer of any Certificate, the Certificate Administrator shall execute, authenticate and deliver, in the name of the designated transferee or transferees, one or more new Certificates in authorized denominations, in like aggregate interest and of the same Class.

Notwithstanding the foregoing, no such amendment (A) may change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations of any Mortgage Loan Seller under any Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller or (B) may materially and adversely affect the holders of a Companion Loan without such Companion Holder’s consent.

The Pooling and Servicing Agreement may also be amended from time to time by the parties thereto with the consent of the Holders of Certificates of each Class affected by such amendment (including, for the avoidance of doubt, any Holders of the VRR Interest, the Y&L Towers VRR

A-18-10

Interest or the Standard Highline VRR Interest to the extent any such amendment would adversely affect the rights of such Certificateholders) evidencing in the aggregate not less than a majority of the aggregate Percentage Interests constituting the Class for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of the Pooling and Servicing Agreement or of modifying in any manner the rights of the Holders of Certificates of such Class; provided, however, that no such amendment shall:

(i) reduce in any manner the amount of, or delay the timing of, payments received on the Mortgage Loans or the Trust Subordinate Companion Loans that are required to be distributed on a Certificate of any class without the consent of the Holder of the Certificate or which are required to be distributed to a Companion Holder without the consent of such Companion Holder; or

(ii) reduce the aforesaid percentage of Certificates of any Class the Holders of which are required to consent to any such amendment or remove the requirement to obtain consent of any Companion Holder or Holder of Loan-Specific Certificates, in any such case, without the consent of the Holders of all Certificates of such Class then-outstanding or such Companion Holders, as applicable; or

(iii) adversely affect the Voting Rights of any Class of Certificates without the consent of the Holders of all Certificates of such Class then outstanding; or

(v) amend the Servicing Standard without the consent of 100% of the Certificateholders or receipt of Rating Agency Confirmation from each Rating Agency and confirmation of the applicable rating agencies that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings of any Serviced Companion Loan Securities, if any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement) and, if required under the related Intercreditor Agreement, the consent of the holder of any AB Subordinate Companion Loan for each Serviced AB Whole Loan.

Notwithstanding the foregoing, none of the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Depositor, the Master Servicer nor the Special Servicer will be required to consent to any amendment to the Pooling and Servicing Agreement without having first received an Opinion of Counsel (at the Trust’s expense) to the

A-18-11

effect that such amendment is permitted under the Pooling and Servicing Agreement, that all conditions precedent have been satisfied and that such amendment or the exercise of any power granted to the Master Servicer, the Special Servicer, the Depositor, the Trustee, the Certificate Administrator, the Operating Advisor, the Asset Representations Reviewer or any other specified person in accordance with such amendment will not result in the imposition of a tax on any portion of the Trust Fund or any Trust REMIC, or cause any Trust REMIC to fail to qualify as a REMIC or cause the Grantor Trust to fail to qualify as a grantor trust under the relevant provisions of the Code.

The Holders of the majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates may, in that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the Certificate Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage Loans (and all property acquired through exercise of remedies in respect of any related Mortgage Loan), the Trust Subordinate Companion Loans and the Trust’s portion of each REO Property remaining in the Trust Fund, and thereby effect termination of the Trust and early retirement of the then-outstanding Certificates, only on or after the first Distribution Date on which the aggregate Stated Principal Balances of the Mortgage Loans, the Trust Subordinate Companion Loans and the portion of any REO Loans held by the Trust is less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage Loans (solely for the purposes of this calculation, if such right is being exercised after December 2027 and the 237 East Fordham Road Mortgage Loan is still an asset of the Trust, then such Mortgage Loan will be excluded from the then-aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate Companion Loans and from the aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate Companion Loans as of the Cut-off Date) as set forth in the Pooling and Servicing Agreement.

Following the date on which the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class A-S, Class X-A, Class X-B, Class X-E, Class B and Class C Regular Interests have been reduced to zero (and provided that there is only one Holder (or multiple Holders acting in unanimity) of the then-outstanding Certificates (other than the Class Z and Class R Certificates)), the Sole Certificateholder shall have the right, with the consent of the Master Servicer, to exchange all of its Certificates (other than the Class Z and Class R Certificates) together with the payment or deemed payment of the Termination Purchase Amount for all of the Mortgage Loans, the Trust Subordinate Companion Loans and each REO Property remaining in the Trust Fund pursuant to the terms of the Pooling and Servicing Agreement.

The obligations created by the Pooling and Servicing Agreement and the Trust created thereby (other than the obligation of the Certificate Administrator to make payments to Certificateholders as provided for in the Pooling and Servicing Agreement), shall terminate upon reduction of the Certificate Balances of all the Certificates to zero (including, without limitation, any such final payment resulting from a termination of the Trust due to a sale of its property) pursuant to the terms of the Pooling and Servicing Agreement. In no event, however, will the Trust created by the Pooling and Servicing Agreement continue beyond the expiration of 21 years from the death of the last survivor of the descendants of Joseph P. Kennedy, the late Ambassador of the United States to the Court of St. James, living on the date hereof.

This Certificate is issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of November 1, 2017 (the “Pooling and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities Corp., as Depositor, Wells Fargo Bank, National Association, as Certificate Administrator and as Trustee, Park Bridge Lender Services LLC, as Operating Advisor and as Asset Representations Reviewer, KeyBank National Association, as Master Servicer, and CWCapital Asset Management LLC, as Special Servicer. To the extent not defined herein, capitalized terms used herein shall have the meanings assigned thereto in the Pooling and Servicing Agreement.

This Certificate represents a beneficial ownership of Excess Interest and the Excess Interest Distribution Account. Each Holder of this Certificate, by acceptance hereof, agrees to treat, and take no action inconsistent with the treatment of, this Certificate in accordance with the preceding sentence for purposes of federal income taxes, state and local income and franchise taxes and other taxes imposed on or measured by income.

The Certificate Administrator makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates, the Mortgage Loans or the Trust Subordinate Companion Loans and has executed this Certificate in its limited capacity as Certificate Administrator under the Pooling and Servicing Agreement.

Pursuant to the terms of the Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution on any Certificate), on the 4th Business Day following the determination date of each month, commencing in December 2017 (each such date, a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related Record Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this Certificate) of that portion of the aggregate amount, if any, allocable to the Class Z Certificates for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement.

All distributions (other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons in whose names the Certificates are registered at the close of business on each Record Date, which will be the close of business on the last Business Day of the month immediately preceding the month in which such Distribution Date occurs. Distributions are required to be made (a) by wire transfer of immediately available funds to the account of such Certificateholder at a bank or other entity having appropriate facilities therefor, if such Certificateholder provided the Certificate Administrator with written wiring instructions

A-18-3

no less than five Business Days prior to the related Record Date (which wiring instructions may be in the form of a standing order applicable to all subsequent Distribution Dates), or otherwise (b) by check mailed to such Certificateholder at its address in the Certificate Register. The final distribution on each Certificate will be made in like manner, but only upon presentment and surrender of such Certificate at the offices of the Certificate Registrar or such other location specified in the notice to Certificateholders of such final distribution.

Any funds not distributed to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure of such Certificateholders to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited to the account or accounts of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been given pursuant to Section 4.01(l) of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within six months after the time specified in such notice, the Certificate Administrator shall mail a second notice to the remaining non tendering Certificateholders to surrender their Certificates for cancellation in order to receive the final distribution with respect thereto. If within one year after the second notice all such Certificates shall not have been surrendered for cancellation, the Certificate Administrator, directly or through an agent, shall take such steps to contact the remaining non tendering Certificateholders concerning the surrender of their Certificates as it shall deem appropriate and subject to escheatment and other applicable laws. The costs and expenses of holding such funds in trust and of contacting such Certificateholders following the first anniversary of the delivery of such second notice to the non-tendering Certificateholders shall be paid out of such funds. No interest shall accrue or be payable to any Certificateholder on any amount held in trust under the Pooling and Servicing Agreement by the Certificate Administrator as a result of such Certificateholder’s failure to surrender its Certificate(s) for final payment thereof in accordance with Section 4.01(l) of the Pooling and Servicing Agreement.

This Certificate is limited in right of payment to, among other things, certain collections and recoveries in respect of the Mortgage Loans, as more specifically set forth herein and in the Pooling and Servicing Agreement.

As provided in the Pooling and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject to the Pooling and Servicing Agreement (including any Qualified Substitute Mortgage Loan replacing a removed Mortgage Loan) and the Trust Subordinate Companion Loans, together with the Mortgage Files relating thereto (subject to, in the case of a Serviced Whole Loan, the interests of the related Serviced Companion Noteholder in the related Mortgage File); (ii) all scheduled or unscheduled payments on or collections in respect of the Mortgage Loans and the Trust Subordinate Companion Loans due after the Cut-off Date (or with respect to a Qualified Substitute Mortgage Loan, the Due Date in the month of substitution); (iii) any REO Property (to the extent of the Trust’s interest therein) or the Trust’s beneficial interest in the Mortgaged Property securing a Non Serviced Whole Loan acquired under the related Non-Serviced PSA; (iv) all revenues received in respect of any REO Property (to the extent of the Trust’s interest therein); (v) the Master Servicer’s, the Special Servicer’s, the Certificate Administrator’s and the Trustee’s rights under the insurance policies with respect to the Mortgage Loans and the Trust Subordinate Companion Loans required to be maintained pursuant to the Pooling and Servicing Agreement and any proceeds thereof (to the extent of the Trust’s interest therein); (vi) any Assignment of Leases and any security agreements

A-18-4

(to the extent of the Trust’s interest therein); (vii) any letters of credit, indemnities, guaranties or lease enhancement policies given as additional security for any related Mortgage Loans or Trust Subordinate Companion Loans (to the extent of the Trust’s interest therein); (viii) all assets deposited in the Loss of Value Reserve Fund and the Servicing Accounts (to the extent of the Trust’s interest therein), amounts on deposit in the Collection Account (to the extent of the Trust’s interest therein), the Lower-Tier REMIC Distribution Account, the Upper-Tier REMIC Distribution Account, the Trust Subordinate Companion Loan REMIC Distribution Accounts, the Regular Interest Distribution Account, the Excess Interest Distribution Account, the Interest Reserve Account, the Gain-on-Sale Reserve Account (to the extent of the Trust’s interest therein) and any REO Account (to the extent of the Trust’s interest therein), including any reinvestment income, as applicable; (ix) any Environmental Indemnity Agreements (to the extent of the Trust’s interest therein); (x) the rights and remedies of the Depositor under each Mortgage Loan Purchase Agreement (to the extent transferred to the Trustee); (xi) the Lower-Tier Regular Interests; (xii) the Trust Subordinate Companion Loan REMIC Regular Interests; and (xiii) the proceeds of the foregoing (other than any interest earned on deposits in the lock-box accounts, cash collateral accounts, escrow accounts and any reserve accounts, to the extent such interest belongs to the related Mortgagor).

This Certificate does not purport to summarize the Pooling and Servicing Agreement, and reference is made to the Pooling and Servicing Agreement for the interests, rights, benefits, obligations and duties evidenced hereby, and the limitations thereon, and the rights, duties and immunities of the Certificate Administrator and Trustee.

As provided in the Pooling and Servicing Agreement, subject to certain restrictions on transfer set forth therein, upon surrender for registration of transfer of any Certificate, the Certificate Administrator shall execute, authenticate and deliver, in the name of the designated transferee or transferees, one or more new Certificates in authorized denominations, in like aggregate interest and of the same Class.

(iii) to change the timing and/or nature of deposits in the Collection Account, the Distribution Accounts or any REO Account; provided that (a) the P&I Advance Date shall in no event be later than the Business Day prior to the related Distribution Date and (b) such change shall not adversely affect in any material respect the interests of any Certificateholder (including, for the avoidance of doubt, any Holder of a VRR Interest, a Y&L Towers VRR Interest or a Standard Highline VRR Interest), as evidenced in writing by an Opinion of Counsel at the expense of the party requesting such amendment or as evidenced by a Rating Agency Confirmation from each Rating Agency with respect to such amendment;

(iv) to modify, eliminate or add to any provisions of the Pooling and Servicing Agreement to such extent as shall be necessary to maintain the qualification of any Trust REMIC as a REMIC or the Grantor Trust as a grantor trust under the relevant provisions of the Code at all times that any Certificate is outstanding, or to avoid or minimize the risk of imposition of any tax on the Trust or any Trust REMIC or the Grantor Trust; provided that the Trustee and the Certificate Administrator have received an Opinion of Counsel (at the expense of the party requesting such amendment) to the effect that (a) such action is necessary or desirable to maintain such qualification or to avoid or minimize the risk of the imposition of any such tax and (b) such action will not adversely affect in any material respect the interests of any Certificateholder (including, for the avoidance of doubt, any Holder of a VRR Interest, a Y&L Towers VRR Interest or a Standard Highline VRR Interest), or Companion Holder;

(v) to modify, eliminate or add to the provisions of Section 5.03(o) of the Pooling and Servicing Agreement or any other provision of the Pooling and Servicing Agreement restricting transfer of the Class R Certificates; provided the Depositor has determined that such change shall not, as evidenced by an Opinion of Counsel, cause the Trust, any Trust REMIC or any of the Certificateholders (other than the Transferor) to be subject to a federal tax caused by a Transfer to a Person that is a Disqualified Organization or a Non-U.S. Tax Person;

(xi) to modify, eliminate or add to any of its provisions in the event the Credit Risk Retention Rules or any other regulations applicable to the risk retention requirements for this securitization transaction are amended or repealed, to the extent required to comply with any such amendment or to modify or eliminate the provision related to the risk retention requirements in the event of such repeal.

Notwithstanding the foregoing, no such amendment (A) may change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations of any Mortgage Loan Seller under any Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller or (B) may materially and adversely affect the holders of a Companion Loan without such Companion Holder’s consent.

The Pooling and Servicing Agreement may also be amended from time to time by the parties thereto with the consent of the Holders of Certificates of each Class affected by such amendment (including, for the avoidance of doubt, any Holders of the VRR Interest, the Y&L Towers VRR

A-18-8

Interest or the Standard Highline VRR Interest to the extent any such amendment would adversely affect the rights of such Certificateholders) evidencing in the aggregate not less than a majority of the aggregate Percentage Interests constituting the Class for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of the Pooling and Servicing Agreement or of modifying in any manner the rights of the Holders of Certificates of such Class; provided, however, that no such amendment shall:

(i) reduce in any manner the amount of, or delay the timing of, payments received on the Mortgage Loans or the Trust Subordinate Companion Loans that are required to be distributed on a Certificate of any class without the consent of the Holder of the Certificate or which are required to be distributed to a Companion Holder without the consent of such Companion Holder; or

(ii) reduce the aforesaid percentage of Certificates of any Class the Holders of which are required to consent to any such amendment or remove the requirement to obtain consent of any Companion Holder or Holder of Loan-Specific Certificates, in any such case, without the consent of the Holders of all Certificates of such Class then-outstanding or such Companion Holders, as applicable; or

(iii) adversely affect the Voting Rights of any Class of Certificates without the consent of the Holders of all Certificates of such Class then outstanding; or

(iv) change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations of any Mortgage Loan Seller under such Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller; or

(v) amend the Servicing Standard without the consent of 100% of the Certificateholders or receipt of Rating Agency Confirmation from each Rating Agency and confirmation of the applicable rating agencies that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings of any Serviced Companion Loan Securities, if any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement) and, if required under the related Intercreditor Agreement, the consent of the holder of any AB Subordinate Companion Loan for each Serviced AB Whole Loan.

Notwithstanding the foregoing, none of the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Depositor, the Master Servicer nor the Special Servicer will be required to consent to any amendment to the Pooling and Servicing Agreement without having first received an Opinion of Counsel (at the Trust’s expense) to the

A-18-9

effect that such amendment is permitted under the Pooling and Servicing Agreement, that all conditions precedent have been satisfied and that such amendment or the exercise of any power granted to the Master Servicer, the Special Servicer, the Depositor, the Trustee, the Certificate Administrator, the Operating Advisor, the Asset Representations Reviewer or any other specified person in accordance with such amendment will not result in the imposition of a tax on any portion of the Trust Fund or any Trust REMIC, or cause any Trust REMIC to fail to qualify as a REMIC or cause the Grantor Trust to fail to qualify as a grantor trust under the relevant provisions of the Code.

The Holders of the majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates may, in that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the Certificate Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage Loans (and all property acquired through exercise of remedies in respect of any related Mortgage Loan), the Trust Subordinate Companion Loans and the Trust’s portion of each REO Property remaining in the Trust Fund, and thereby effect termination of the Trust and early retirement of the then-outstanding Certificates, only on or after the first Distribution Date on which the aggregate Stated Principal Balances of the Mortgage Loans, the Trust Subordinate Companion Loans and the portion of any REO Loans held by the Trust is less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage Loans (solely for the purposes of this calculation, if such right is being exercised after December 2027 and the 237 East Fordham Road Mortgage Loan is still an asset of the Trust, then such Mortgage Loan will be excluded from the then-aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate Companion Loans and from the aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate Companion Loans as of the Cut-off Date) as set forth in the Pooling and Servicing Agreement.

Following the date on which the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class A-S, Class X-A, Class X-B, Class X-E, Class B and Class C Regular Interests have been reduced to zero (and provided that there is only one Holder (or multiple Holders acting in unanimity) of the then-outstanding Certificates (other than the Class Z and Class R Certificates)), the Sole Certificateholder shall have the right, with the consent of the Master Servicer, to exchange all of its Certificates (other than the Class Z and Class R Certificates) together with the payment or deemed payment of the Termination Purchase Amount for all of the Mortgage Loans, the Trust Subordinate Companion Loans and each REO Property remaining in the Trust Fund pursuant to the terms of the Pooling and Servicing Agreement.

The obligations created by the Pooling and Servicing Agreement and the Trust created thereby (other than the obligation of the Certificate Administrator to make payments to Certificateholders as provided for in the Pooling and Servicing Agreement), shall terminate upon reduction of the Certificate Balances of all the Certificates to zero (including, without limitation, any such final payment resulting from a termination of the Trust due to a sale of its property) pursuant to the terms of the Pooling and Servicing Agreement. In no event, however, will the Trust created by the Pooling and Servicing Agreement continue beyond the expiration of 21 years from the death of the last survivor of the descendants of Joseph P. Kennedy, the late Ambassador of the United States to the Court of St. James, living on the date hereof.

This certifies that [              ] is the registered owner of a beneficial ownership interest in a Trust Fund, including the distributions to be made with respect to the Class V1-A Certificates. The Trust Fund, described more fully below, consists primarily of a pool of Mortgage Loans secured by first liens on commercial and multifamily properties and subordinate interests in two subordinate companion loans (the “Trust Subordinate Companion Loans”) held in trust by the Trustee and serviced by the Master Servicer. The Trust Fund was created, and the Mortgage Loans and the Trust Subordinate Companion Loans are to be serviced, pursuant to the Pooling and Servicing Agreement (as defined below). The Holder of this Certificate, by virtue of the acceptance hereof, assents to the terms, provisions and conditions of the Pooling and Servicing Agreement and is bound thereby. In the event that there is any conflict between any provision of this Certificate and any provision of the Pooling and Servicing Agreement, such provision of this

A-19-3

Certificate shall be superseded to the extent of such inconsistency. Also issued under the Pooling and Servicing Agreement are the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class X-A, Class X-B, Class X-E, Class A-S, Class B, Class C, Class D, Class E, Class F, Class NR, Class V1-B, Class V1-D, Class V1-E, Class V1-F, Class V1-Z, Class V2-A, Class V2-Z, Class UES-A, Class UES-B, Class UES-C, Class UES-D, Class UES-X, Class STN-A, Class STN-B, Class STN-X, Class STN-C, Class V1-UESA, Class V1-UESD, Class V2-UES, Class V1-STNA, Class V1-STNC, Class V2-STN, Class R and Class Z Certificates (together with the Class V1-A Certificates, the “Certificates”; the Holders of Certificates are collectively referred to herein as “Certificateholders”).

This Certificate is issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of November 1, 2017 (the “Pooling and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities Corp., as Depositor, Wells Fargo Bank, National Association, as Certificate Administrator and as Trustee, Park Bridge Lender Services LLC, as Operating Advisor and as Asset Representations Reviewer, KeyBank National Association, as Master Servicer, and CWCapital Asset Management LLC, as Special Servicer. To the extent not defined herein, capitalized terms used herein shall have the meanings assigned thereto in the Pooling and Servicing Agreement.

This Certificate represents beneficial ownership of multiple “regular interests” in a “real estate mortgage investment conduit,” as those terms are defined, respectively, in Sections 860G(a)(1) and 860D of the Internal Revenue Code of 1986, as amended.

The Certificate Administrator makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates, the Mortgage Loans or the Trust Subordinate Companion Loans and has executed this Certificate in its limited capacity as Certificate Administrator under the Pooling and Servicing Agreement.

Pursuant to the terms of the Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution on any Certificate), on the 4th Business Day following the determination date of each month, commencing in December 2017 (each such date, a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related Record Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this Certificate) of that portion of the aggregate amount of principal and interest then distributable, if any, allocable to the Class V1-A Certificates for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement. Holders of this Certificate may be entitled to Yield Maintenance Charges, as provided in the Pooling and Servicing Agreement.

Interest accrued on this Certificate during an Interest Accrual Period, plus the aggregate unpaid Interest Shortfall with respect to this Certificate, if any, will be payable on the related Distribution Date to the extent provided in the Pooling and Servicing Agreement. The “Interest Accrual Period” with respect to any Distribution Date and with respect to the Class V1-A Certificates is the calendar month immediately preceding the month in which such Distribution Date occurs and is assumed to consist of 30 days.

All distributions (other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons in whose names the Certificates are registered at the

A-19-4

close of business on each Record Date, which will be the close of business on the last Business Day of the month immediately preceding the month in which such Distribution Date occurs. Distributions are required to be made (a) by wire transfer of immediately available funds to the account of such Certificateholder at a bank or other entity having appropriate facilities therefor, if such Certificateholder provided the Certificate Administrator with written wiring instructions no less than five Business Days prior to the related Record Date (which wiring instructions may be in the form of a standing order applicable to all subsequent Distribution Dates), or otherwise (b) by check mailed to such Certificateholder at its address in the Certificate Register. The final distribution on each Certificate will be made in like manner, but only upon presentment and surrender of such Certificate at the offices of the Certificate Registrar or such other location specified in the notice to Certificateholders of such final distribution.

Any funds not distributed to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure of such Certificateholders to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited to the account or accounts of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been given pursuant to Section 4.01(l) of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within six months after the time specified in such notice, the Certificate Administrator shall mail a second notice to the remaining non tendering Certificateholders to surrender their Certificates for cancellation in order to receive the final distribution with respect thereto. If within one year after the second notice all such Certificates shall not have been surrendered for cancellation, the Certificate Administrator, directly or through an agent, shall take such steps to contact the remaining non tendering Certificateholders concerning the surrender of their Certificates as it shall deem appropriate and subject to escheatment and other applicable laws. The costs and expenses of holding such funds in trust and of contacting such Certificateholders following the first anniversary of the delivery of such second notice to the non-tendering Certificateholders shall be paid out of such funds. No interest shall accrue or be payable to any Certificateholder on any amount held in trust under the Pooling and Servicing Agreement by the Certificate Administrator as a result of such Certificateholder’s failure to surrender its Certificate(s) for final payment thereof in accordance with Section 4.01(l) of the Pooling and Servicing Agreement.

This Certificate is limited in right of payment to, among other things, certain collections and recoveries in respect of the Mortgage Loans, as more specifically set forth herein and in the Pooling and Servicing Agreement.

As provided in the Pooling and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject to the Pooling and Servicing Agreement (including any Qualified Substitute Mortgage Loan replacing a removed Mortgage Loan) and the Trust Subordinate Companion Loans, together with the Mortgage Files relating thereto (subject to, in the case of a Serviced Whole Loan, the interests of the related Serviced Companion Noteholder in the related Mortgage File); (ii) all scheduled or unscheduled payments on or collections in respect of the Mortgage Loans and the Trust Subordinate Companion Loans due after the Cut-off Date (or with respect to a Qualified Substitute Mortgage Loan, the Due Date in the month of substitution); (iii) any REO Property (to the extent of the Trust’s interest therein) or the Trust’s beneficial interest in the Mortgaged Property securing a Non Serviced Whole Loan acquired under the related Non-Serviced PSA; (iv) all revenues received in respect of any REO

A-19-5

Property (to the extent of the Trust’s interest therein); (v) the Master Servicer’s, the Special Servicer’s, the Certificate Administrator’s and the Trustee’s rights under the insurance policies with respect to the Mortgage Loans and the Trust Subordinate Companion Loans required to be maintained pursuant to the Pooling and Servicing Agreement and any proceeds thereof (to the extent of the Trust’s interest therein); (vi) any Assignment of Leases and any security agreements (to the extent of the Trust’s interest therein); (vii) any letters of credit, indemnities, guaranties or lease enhancement policies given as additional security for any related Mortgage Loans or Trust Subordinate Companion Loans (to the extent of the Trust’s interest therein); (viii) all assets deposited in the Loss of Value Reserve Fund and the Servicing Accounts (to the extent of the Trust’s interest therein), amounts on deposit in the Collection Account (to the extent of the Trust’s interest therein), the Lower-Tier REMIC Distribution Account, the Upper-Tier REMIC Distribution Account, the Trust Subordinate Companion Loan REMIC Distribution Accounts, the Regular Interest Distribution Account, the Excess Interest Distribution Account, the Interest Reserve Account, the Gain-on-Sale Reserve Account (to the extent of the Trust’s interest therein) and any REO Account (to the extent of the Trust’s interest therein), including any reinvestment income, as applicable; (ix) any Environmental Indemnity Agreements (to the extent of the Trust’s interest therein); (x) the rights and remedies of the Depositor under each Mortgage Loan Purchase Agreement (to the extent transferred to the Trustee); (xi) the Lower-Tier Regular Interests; (xii) the Trust Subordinate Companion Loan REMIC Regular Interests; and (xiii) the proceeds of the foregoing (other than any interest earned on deposits in the lock-box accounts, cash collateral accounts, escrow accounts and any reserve accounts, to the extent such interest belongs to the related Mortgagor).

This Certificate does not purport to summarize the Pooling and Servicing Agreement, and reference is made to the Pooling and Servicing Agreement for the interests, rights, benefits, obligations and duties evidenced hereby, and the limitations thereon, and the rights, duties and immunities of the Certificate Administrator and Trustee.

As provided in the Pooling and Servicing Agreement, subject to certain restrictions on transfer set forth therein, upon surrender for registration of transfer of any Certificate, the Certificate Administrator shall execute, authenticate and deliver, in the name of the designated transferee or transferees, one or more new Certificates in authorized denominations, in like aggregate interest and of the same Class.

Prior to due presentation of this Certificate for registration of transfer, the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Certificate Registrar, and any agent of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate Registrar may treat the Person in whose name any Certificate is registered as the owner of such Certificate for the purpose of receiving distributions as provided in the Pooling and Servicing Agreement and for all other purposes whatsoever, and none of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Certificate Registrar, or any agent of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate Registrar shall be affected by any notice to the contrary.

(vi) to revise or add any other provisions with respect to matters or questions arising under the Pooling and Servicing Agreement or any other change; provided that the required action shall not adversely affect in any material respect the interests of any Certificateholder (including, for the avoidance of doubt, any Holder of a VRR Interest, a Y&L Towers VRR Interest or a Standard Highline VRR Interest) or any holder of a Serviced Pari Passu Companion Loan not consenting to such revision or addition, as evidenced in writing by an Opinion of Counsel, at the expense of the party requesting such amendment or as evidenced by a Rating Agency Confirmation from each of the Rating Agencies with respect to such amendment or supplement and confirmation of the applicable rating agencies that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings of any class of Serviced Companion Loan Securities, if any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement);

determine that the commercial mortgage backed securities industry standard for such provisions has changed, in order to conform to such industry standard, (b) such modification does not adversely affect the status of any Trust REMIC as a REMIC or the status of the Grantor Trust as a grantor trust under the relevant provisions of the Code, as evidenced by an Opinion of Counsel and (c) each Rating Agency has delivered a Rating Agency Confirmation and, with regard to any class of Serviced Companion Loan Securities, the applicable rating agencies have delivered a confirmation that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement);

(ix) to modify the procedures of the Pooling and Servicing Agreement relating to compliance with Rule 17g-5 of the Exchange Act; provided that such amendment shall not adversely affect in any material respects the interests of any Certificateholders (including, for the avoidance of doubt, any Holders of a VRR Interest, a Y&L Towers VRR Interest or a Standard Highline VRR Interest), as evidenced by (x) an Opinion of Counsel or (y) if any Certificate is then rated, receipt of Rating Agency Confirmation from each Rating Agency rating such Certificates; and provided, further, that the Certificate Administrator shall give notice of any such amendment to the 17g-5 Information Provider for posting to the 17g-5 Information Provider’s Website pursuant to Section 3.13(c) of the Pooling and Servicing Agreement and the Certificate Administrator shall post such notice to the Certificate Administrator’s Website;

(x) to modify, eliminate or add to any provisions of the Pooling and Servicing Agreement to such extent as shall be necessary to comply with the requirements for use of Form SF-3 in registered offerings to the extent provided in CFR 239.45(b)(1)(ii), (iii) or (iv); or

(xi) to modify, eliminate or add to any of its provisions in the event the Credit Risk Retention Rules or any other regulations applicable to the risk retention requirements for this securitization transaction are amended or repealed, to the extent required to comply with any such amendment or to modify or eliminate the provision related to the risk retention requirements in the event of such repeal.

Notwithstanding the foregoing, no such amendment (A) may change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations of any Mortgage Loan Seller under any Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller or (B) may materially and adversely affect the holders of a Companion Loan without such Companion Holder’s consent.

A-19-9

The Pooling and Servicing Agreement may also be amended from time to time by the parties thereto with the consent of the Holders of Certificates of each Class affected by such amendment (including, for the avoidance of doubt, any Holders of the VRR Interest, the Y&L Towers VRR Interest or the Standard Highline VRR Interest to the extent any such amendment would adversely affect the rights of such Certificateholders) evidencing in the aggregate not less than a majority of the aggregate Percentage Interests constituting the Class for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of the Pooling and Servicing Agreement or of modifying in any manner the rights of the Holders of Certificates of such Class; provided, however, that no such amendment shall:

(i) reduce in any manner the amount of, or delay the timing of, payments received on the Mortgage Loans or the Trust Subordinate Companion Loans that are required to be distributed on a Certificate of any class without the consent of the Holder of the Certificate or which are required to be distributed to a Companion Holder without the consent of such Companion Holder; or

(ii) reduce the aforesaid percentage of Certificates of any Class the Holders of which are required to consent to any such amendment or remove the requirement to obtain consent of any Companion Holder or Holder of Loan-Specific Certificates, in any such case, without the consent of the Holders of all Certificates of such Class then-outstanding or such Companion Holders, as applicable; or

(iii) adversely affect the Voting Rights of any Class of Certificates without the consent of the Holders of all Certificates of such Class then outstanding; or

(iv) change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations of any Mortgage Loan Seller under such Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller; or

(v) amend the Servicing Standard without the consent of 100% of the Certificateholders or receipt of Rating Agency Confirmation from each Rating Agency and confirmation of the applicable rating agencies that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings of any Serviced Companion Loan Securities, if any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement) and, if required under the related Intercreditor Agreement, the consent of the holder of any AB Subordinate Companion Loan for each Serviced AB Whole Loan.

A-19-10

Notwithstanding the foregoing, none of the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Depositor, the Master Servicer nor the Special Servicer will be required to consent to any amendment to the Pooling and Servicing Agreement without having first received an Opinion of Counsel (at the Trust’s expense) to the effect that such amendment is permitted under the Pooling and Servicing Agreement, that all conditions precedent have been satisfied and that such amendment or the exercise of any power granted to the Master Servicer, the Special Servicer, the Depositor, the Trustee, the Certificate Administrator, the Operating Advisor, the Asset Representations Reviewer or any other specified person in accordance with such amendment will not result in the imposition of a tax on any portion of the Trust Fund or any Trust REMIC, or cause any Trust REMIC to fail to qualify as a REMIC or cause the Grantor Trust to fail to qualify as a grantor trust under the relevant provisions of the Code.

The Holders of the majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates may, in that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the Certificate Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage Loans (and all property acquired through exercise of remedies in respect of any related Mortgage Loan), the Trust Subordinate Companion Loans and the Trust’s portion of each REO Property remaining in the Trust Fund, and thereby effect termination of the Trust and early retirement of the then-outstanding Certificates, only on or after the first Distribution Date on which the aggregate Stated Principal Balances of the Mortgage Loans, the Trust Subordinate Companion Loans and the portion of any REO Loans held by the Trust is less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage Loans (solely for the purposes of this calculation, if such right is being exercised after December 2027 and the 237 East Fordham Road Mortgage Loan is still an asset of the Trust, then such Mortgage Loan will be excluded from the then-aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate Companion Loans and from the aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate Companion Loans as of the Cut-off Date) as set forth in the Pooling and Servicing Agreement.

Following the date on which the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class A-S, Class X-A, Class X-B, Class X-E, Class B and Class C Regular Interests have been reduced to zero (and provided that there is only one Holder (or multiple Holders acting in unanimity) of the then-outstanding Certificates (other than the Class Z and Class R Certificates)), the Sole Certificateholder shall have the right, with the consent of the Master Servicer, to exchange all of its Certificates (other than the Class Z and Class R Certificates) together with the payment or deemed payment of the Termination Purchase Amount for all of the Mortgage Loans, the Trust Subordinate Companion Loans and each REO Property remaining in the Trust Fund pursuant to the terms of the Pooling and Servicing Agreement.

The obligations created by the Pooling and Servicing Agreement and the Trust created thereby (other than the obligation of the Certificate Administrator to make payments to Certificateholders as provided for in the Pooling and Servicing Agreement), shall terminate upon reduction of the Certificate Balances of all the Certificates to zero (including, without limitation, any such final payment resulting from a termination of the Trust due to a sale of its property) pursuant to the terms of the Pooling and Servicing Agreement. In no event, however, will the

A-19-11

Trust created by the Pooling and Servicing Agreement continue beyond the expiration of 21 years from the death of the last survivor of the descendants of Joseph P. Kennedy, the late Ambassador of the United States to the Court of St. James, living on the date hereof.

Unless the certificate of authentication hereon has been executed by the Authenticating Agent, by manual signature, this Certificate shall not be entitled to any benefit under the Pooling and Servicing Agreement or be valid for any purpose. The Certificate Registrar has executed this Certificate on behalf of the Trust as Certificate Registrar under the Pooling and Servicing Agreement and makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates, the Mortgage Loans or the Trust Subordinate Companion Loans.

This certifies that [              ] is the registered owner of a beneficial ownership interest in a Trust Fund, including the distributions to be made with respect to the Class V1-B Certificates. The Trust Fund, described more fully below, consists primarily of a pool of Mortgage Loans secured by first liens on commercial and multifamily properties and subordinate interests in two subordinate companion loans (the “Trust Subordinate Companion Loans”) held in trust by the Trustee and serviced by the Master Servicer. The Trust Fund was created, and the Mortgage Loans and the Trust Subordinate Companion Loans are to be serviced, pursuant to the Pooling and Servicing Agreement (as defined below). The Holder of this Certificate, by virtue of the acceptance hereof, assents to the terms, provisions and conditions of the Pooling and Servicing Agreement and is bound thereby. In the event that there is any conflict between any provision of this Certificate and any provision of the Pooling and Servicing Agreement, such provision of this Certificate shall be superseded to the extent of such inconsistency. Also issued under the Pooling and Servicing Agreement are the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5,

Class A-SB, Class X-A, Class X-B, Class X-E, Class A-S, Class B, Class C, Class D, Class E, Class F, Class NR, Class V1-A, Class V1-D, Class V1-E, Class V1-F, Class V1-Z, Class V2-A, Class V2-Z, Class UES-A, Class UES-B, Class UES-C, Class UES-D, Class UES-X, Class STN-A, Class STN-B, Class STN-X, Class STN-C, Class V1-UESA, Class V1-UESD, Class V2-UES, Class V1-STNA, Class V1-STNC, Class V2-STN, Class R and Class Z Certificates (together with the Class V1-B Certificates, the “Certificates”; the Holders of Certificates are collectively referred to herein as “Certificateholders”).

This Certificate is issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of November 1, 2017 (the “Pooling and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities Corp., as Depositor, Wells Fargo Bank, National Association, as Certificate Administrator and as Trustee, Park Bridge Lender Services LLC, as Operating Advisor and as Asset Representations Reviewer, KeyBank National Association, as Master Servicer, and CWCapital Asset Management LLC, as Special Servicer. To the extent not defined herein, capitalized terms used herein shall have the meanings assigned thereto in the Pooling and Servicing Agreement.

This Certificate represents beneficial ownership of multiple “regular interests” in a “real estate mortgage investment conduit,” as those terms are defined, respectively, in Sections 860G(a)(1) and 860D of the Internal Revenue Code of 1986, as amended.

The Certificate Administrator makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates, the Mortgage Loans or the Trust Subordinate Companion Loans and has executed this Certificate in its limited capacity as Certificate Administrator under the Pooling and Servicing Agreement.

Pursuant to the terms of the Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution on any Certificate), on the 4th Business Day following the determination date of each month, commencing in December 2017 (each such date, a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related Record Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this Certificate) of that portion of the aggregate amount of principal and interest then distributable, if any, allocable to the Class V1-B Certificates for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement. Holders of this Certificate may be entitled to Yield Maintenance Charges, as provided in the Pooling and Servicing Agreement.

Interest accrued on this Certificate during an Interest Accrual Period, plus the aggregate unpaid Interest Shortfall with respect to this Certificate, if any, will be payable on the related Distribution Date to the extent provided in the Pooling and Servicing Agreement. The “Interest Accrual Period” with respect to any Distribution Date and with respect to the Class V1-B Certificates is the calendar month immediately preceding the month in which such Distribution Date occurs and is assumed to consist of 30 days.

All distributions (other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons in whose names the Certificates are registered at the close of business on each Record Date, which will be the close of business on the last Business Day of the month immediately preceding the month in which such Distribution Date occurs.

A-20-4

Distributions are required to be made (a) by wire transfer of immediately available funds to the account of such Certificateholder at a bank or other entity having appropriate facilities therefor, if such Certificateholder provided the Certificate Administrator with written wiring instructions no less than five Business Days prior to the related Record Date (which wiring instructions may be in the form of a standing order applicable to all subsequent Distribution Dates), or otherwise (b) by check mailed to such Certificateholder at its address in the Certificate Register. The final distribution on each Certificate will be made in like manner, but only upon presentment and surrender of such Certificate at the offices of the Certificate Registrar or such other location specified in the notice to Certificateholders of such final distribution.

Any funds not distributed to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure of such Certificateholders to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited to the account or accounts of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been given pursuant to Section 4.01(l) of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within six months after the time specified in such notice, the Certificate Administrator shall mail a second notice to the remaining non tendering Certificateholders to surrender their Certificates for cancellation in order to receive the final distribution with respect thereto. If within one year after the second notice all such Certificates shall not have been surrendered for cancellation, the Certificate Administrator, directly or through an agent, shall take such steps to contact the remaining non tendering Certificateholders concerning the surrender of their Certificates as it shall deem appropriate and subject to escheatment and other applicable laws. The costs and expenses of holding such funds in trust and of contacting such Certificateholders following the first anniversary of the delivery of such second notice to the non-tendering Certificateholders shall be paid out of such funds. No interest shall accrue or be payable to any Certificateholder on any amount held in trust under the Pooling and Servicing Agreement by the Certificate Administrator as a result of such Certificateholder’s failure to surrender its Certificate(s) for final payment thereof in accordance with Section 4.01(l) of the Pooling and Servicing Agreement.

This Certificate is limited in right of payment to, among other things, certain collections and recoveries in respect of the Mortgage Loans, as more specifically set forth herein and in the Pooling and Servicing Agreement.

As provided in the Pooling and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject to the Pooling and Servicing Agreement (including any Qualified Substitute Mortgage Loan replacing a removed Mortgage Loan) and the Trust Subordinate Companion Loans, together with the Mortgage Files relating thereto (subject to, in the case of a Serviced Whole Loan, the interests of the related Serviced Companion Noteholder in the related Mortgage File); (ii) all scheduled or unscheduled payments on or collections in respect of the Mortgage Loans and the Trust Subordinate Companion Loans due after the Cut-off Date (or with respect to a Qualified Substitute Mortgage Loan, the Due Date in the month of substitution); (iii) any REO Property (to the extent of the Trust’s interest therein) or the Trust’s beneficial interest in the Mortgaged Property securing a Non Serviced Whole Loan acquired under the related Non-Serviced PSA; (iv) all revenues received in respect of any REO Property (to the extent of the Trust’s interest therein); (v) the Master Servicer’s, the Special Servicer’s, the Certificate Administrator’s and the Trustee’s rights under the insurance policies

A-20-5

with respect to the Mortgage Loans and the Trust Subordinate Companion Loans required to be maintained pursuant to the Pooling and Servicing Agreement and any proceeds thereof (to the extent of the Trust’s interest therein); (vi) any Assignment of Leases and any security agreements (to the extent of the Trust’s interest therein); (vii) any letters of credit, indemnities, guaranties or lease enhancement policies given as additional security for any related Mortgage Loans or Trust Subordinate Companion Loans (to the extent of the Trust’s interest therein); (viii) all assets deposited in the Loss of Value Reserve Fund and the Servicing Accounts (to the extent of the Trust’s interest therein), amounts on deposit in the Collection Account (to the extent of the Trust’s interest therein), the Lower-Tier REMIC Distribution Account, the Upper-Tier REMIC Distribution Account, the Trust Subordinate Companion Loan REMIC Distribution Accounts, the Regular Interest Distribution Account, the Excess Interest Distribution Account, the Interest Reserve Account, the Gain-on-Sale Reserve Account (to the extent of the Trust’s interest therein) and any REO Account (to the extent of the Trust’s interest therein), including any reinvestment income, as applicable; (ix) any Environmental Indemnity Agreements (to the extent of the Trust’s interest therein); (x) the rights and remedies of the Depositor under each Mortgage Loan Purchase Agreement (to the extent transferred to the Trustee); (xi) the Lower-Tier Regular Interests; (xii) the Trust Subordinate Companion Loan REMIC Regular Interests; and (xiii) the proceeds of the foregoing (other than any interest earned on deposits in the lock-box accounts, cash collateral accounts, escrow accounts and any reserve accounts, to the extent such interest belongs to the related Mortgagor).

This Certificate does not purport to summarize the Pooling and Servicing Agreement, and reference is made to the Pooling and Servicing Agreement for the interests, rights, benefits, obligations and duties evidenced hereby, and the limitations thereon, and the rights, duties and immunities of the Certificate Administrator and Trustee.

As provided in the Pooling and Servicing Agreement, subject to certain restrictions on transfer set forth therein, upon surrender for registration of transfer of any Certificate, the Certificate Administrator shall execute, authenticate and deliver, in the name of the designated transferee or transferees, one or more new Certificates in authorized denominations, in like aggregate interest and of the same Class.

Prior to due presentation of this Certificate for registration of transfer, the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Certificate Registrar, and any agent of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate Registrar may treat the Person in whose name any Certificate is registered as the owner of such Certificate for the purpose of receiving distributions as provided in the Pooling and Servicing Agreement and for all other purposes whatsoever, and none of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Certificate Registrar, or any agent of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate Registrar shall be affected by any notice to the contrary.

(i) reduce in any manner the amount of, or delay the timing of, payments received on the Mortgage Loans or the Trust Subordinate Companion Loans that are required to be distributed on a Certificate of any class without the consent of the Holder of the Certificate or which are required to be distributed to a Companion Holder without the consent of such Companion Holder; or

(ii) reduce the aforesaid percentage of Certificates of any Class the Holders of which are required to consent to any such amendment or remove the requirement to obtain consent of any Companion Holder or Holder of Loan-Specific Certificates, in any such case, without the consent of the Holders of all Certificates of such Class then-outstanding or such Companion Holders, as applicable; or

(iii) adversely affect the Voting Rights of any Class of Certificates without the consent of the Holders of all Certificates of such Class then outstanding; or

(iv) change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations of any Mortgage Loan Seller under such Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller; or

(v) amend the Servicing Standard without the consent of 100% of the Certificateholders or receipt of Rating Agency Confirmation from each Rating Agency and confirmation of the applicable rating agencies that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings of any Serviced Companion Loan Securities, if any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement) and, if required under the related Intercreditor Agreement, the consent of the holder of any AB Subordinate Companion Loan for each Serviced AB Whole Loan.

Notwithstanding the foregoing, none of the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Depositor, the Master Servicer nor the Special Servicer will be required to consent to any amendment to the Pooling and Servicing Agreement without having first received an Opinion of Counsel (at the Trust’s expense) to the effect that such amendment is permitted under the Pooling and Servicing Agreement, that all conditions precedent have been satisfied and that such amendment or the exercise of any power granted to the Master Servicer, the Special Servicer, the Depositor, the Trustee, the Certificate Administrator, the Operating Advisor, the Asset Representations Reviewer or any other specified person in accordance with such amendment will not result in the imposition of a tax on any portion of the Trust Fund or any Trust REMIC, or cause any Trust REMIC to fail to qualify as a REMIC or cause the Grantor Trust to fail to qualify as a grantor trust under the relevant provisions of the Code.

The Holders of the majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates may, in that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the Certificate Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage Loans (and all property acquired through exercise of remedies in respect of any related Mortgage Loan), the Trust Subordinate Companion Loans and the Trust’s portion of each REO Property remaining in the Trust Fund, and thereby effect termination of the Trust and early retirement of the then-outstanding Certificates, only on or after the first Distribution Date on which the aggregate Stated Principal Balances of the Mortgage Loans, the Trust Subordinate Companion Loans and the portion of any REO Loans held by the Trust is less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage Loans (solely for the purposes of this calculation, if such right is being exercised after December 2027 and the 237 East Fordham Road Mortgage Loan is still an asset of the Trust, then such Mortgage Loan will be excluded from the then-aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate Companion Loans and from the aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate Companion Loans as of the Cut-off Date) as set forth in the Pooling and Servicing Agreement.

Following the date on which the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class A-S, Class X-A, Class X-B, Class X-E, Class B and Class C Regular Interests have been reduced to zero (and provided that there is only one Holder (or multiple Holders acting in unanimity) of the then-outstanding Certificates (other than the Class Z and Class R Certificates)), the Sole Certificateholder shall have the right, with the consent of the Master Servicer, to exchange all of its Certificates (other than the Class Z and Class R Certificates) together with the payment or deemed payment of the Termination Purchase Amount for all of the Mortgage Loans, the Trust Subordinate Companion Loans and each REO Property remaining in the Trust Fund pursuant to the terms of the Pooling and Servicing Agreement.

The obligations created by the Pooling and Servicing Agreement and the Trust created thereby (other than the obligation of the Certificate Administrator to make payments to Certificateholders as provided for in the Pooling and Servicing Agreement), shall terminate upon reduction of the Certificate Balances of all the Certificates to zero (including, without limitation, any such final payment resulting from a termination of the Trust due to a sale of its property) pursuant to the terms of the Pooling and Servicing Agreement. In no event, however, will the

Trust created by the Pooling and Servicing Agreement continue beyond the expiration of 21 years from the death of the last survivor of the descendants of Joseph P. Kennedy, the late Ambassador of the United States to the Court of St. James, living on the date hereof.

Unless the certificate of authentication hereon has been executed by the Authenticating Agent, by manual signature, this Certificate shall not be entitled to any benefit under the Pooling and Servicing Agreement or be valid for any purpose. The Certificate Registrar has executed this Certificate on behalf of the Trust as Certificate Registrar under the Pooling and Servicing Agreement and makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates, the Mortgage Loans or the Trust Subordinate Companion Loans.

The Holder of this Certificate, by virtue of the acceptance hereof, assents to the terms, provisions and conditions of the Pooling and Servicing Agreement and is bound thereby. In the event that there is any conflict between any provision of this Certificate and any provision of the Pooling and Servicing Agreement, such provision of this Certificate shall be superseded to the extent of such inconsistency. Also issued under the Pooling and Servicing Agreement are the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class X-A, Class X-B, Class X-E, Class A-S, Class B, Class C, Class D, Class E, Class F, Class NR, Class V1-A, Class V1-B, Class V1-E, Class V1-F, Class V1-Z, Class V2-A, Class V2-Z, Class UES-A, Class UES-B, Class UES-C, Class UES-D, Class UES-X, Class STN-A, Class STN-B, Class STN-X, Class STN-C, Class V1-UESA, Class V1-UESD, Class V2-UES, Class V1-STNA, Class V1-STNC, Class V2-STN, Class R and Class Z Certificates (together with the Class V1-D Certificates, the “Certificates”; the Holders of Certificates are collectively referred to herein as “Certificateholders”).

This Certificate is issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of November 1, 2017 (the “Pooling and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities Corp., as Depositor, Wells Fargo Bank, National Association, as Certificate Administrator and as Trustee, Park Bridge Lender Services LLC, as Operating Advisor and as Asset Representations Reviewer, KeyBank National Association, as Master Servicer, and CWCapital Asset Management LLC, as Special Servicer. To the extent not defined herein, capitalized terms used herein shall have the meanings assigned thereto in the Pooling and Servicing Agreement.

This Certificate represents beneficial ownership of a “regular interest” in a “real estate mortgage investment conduit,” as those terms are defined, respectively, in Sections 860G(a)(1) and 860D of the Internal Revenue Code of 1986, as amended.

The Certificate Administrator makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates, the Mortgage Loans or the Trust Subordinate Companion Loans and has executed this Certificate in its limited capacity as Certificate Administrator under the Pooling and Servicing Agreement.

Pursuant to the terms of the Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution on any Certificate), on the 4th Business Day following the determination date of each month, commencing in December 2017 (each such date, a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related Record Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this Certificate) of that portion of the aggregate amount of principal and interest then distributable, if any, allocable to the Class V1-D Certificates for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement. Holders of this Certificate may be entitled to Yield Maintenance Charges, as provided in the Pooling and Servicing Agreement.

Interest accrued on this Certificate during an Interest Accrual Period, plus the aggregate unpaid Interest Shortfall with respect to this Certificate, if any, will be payable on the related Distribution Date to the extent provided in the Pooling and Servicing Agreement. The “Interest Accrual Period” with respect to any Distribution Date and with respect to the Class V1-D

A-21-4

Certificates is the calendar month immediately preceding the month in which such Distribution Date occurs and is assumed to consist of 30 days.

All distributions (other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons in whose names the Certificates are registered at the close of business on each Record Date, which will be the close of business on the last Business Day of the month immediately preceding the month in which such Distribution Date occurs. Distributions are required to be made (a) by wire transfer of immediately available funds to the account of such Certificateholder at a bank or other entity having appropriate facilities therefor, if such Certificateholder provided the Certificate Administrator with written wiring instructions no less than five Business Days prior to the related Record Date (which wiring instructions may be in the form of a standing order applicable to all subsequent Distribution Dates), or otherwise (b) by check mailed to such Certificateholder at its address in the Certificate Register. The final distribution on each Certificate will be made in like manner, but only upon presentment and surrender of such Certificate at the offices of the Certificate Registrar or such other location specified in the notice to Certificateholders of such final distribution.

Any funds not distributed to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure of such Certificateholders to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited to the account or accounts of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been given pursuant to Section 4.01(l) of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within six months after the time specified in such notice, the Certificate Administrator shall mail a second notice to the remaining non tendering Certificateholders to surrender their Certificates for cancellation in order to receive the final distribution with respect thereto. If within one year after the second notice all such Certificates shall not have been surrendered for cancellation, the Certificate Administrator, directly or through an agent, shall take such steps to contact the remaining non tendering Certificateholders concerning the surrender of their Certificates as it shall deem appropriate and subject to escheatment and other applicable laws. The costs and expenses of holding such funds in trust and of contacting such Certificateholders following the first anniversary of the delivery of such second notice to the non-tendering Certificateholders shall be paid out of such funds. No interest shall accrue or be payable to any Certificateholder on any amount held in trust under the Pooling and Servicing Agreement by the Certificate Administrator as a result of such Certificateholder’s failure to surrender its Certificate(s) for final payment thereof in accordance with Section 4.01(l) of the Pooling and Servicing Agreement.

This Certificate is limited in right of payment to, among other things, certain collections and recoveries in respect of the Mortgage Loans, as more specifically set forth herein and in the Pooling and Servicing Agreement.

As provided in the Pooling and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject to the Pooling and Servicing Agreement (including any Qualified Substitute Mortgage Loan replacing a removed Mortgage Loan) and the Trust Subordinate Companion Loans, together with the Mortgage Files relating thereto (subject to, in the case of a Serviced Whole Loan, the interests of the related Serviced Companion Noteholder in the related Mortgage File); (ii) all scheduled or unscheduled payments on or collections in respect of the Mortgage Loans and the Trust Subordinate Companion Loans due

A-21-5

after the Cut-off Date (or with respect to a Qualified Substitute Mortgage Loan, the Due Date in the month of substitution); (iii) any REO Property (to the extent of the Trust’s interest therein) or the Trust’s beneficial interest in the Mortgaged Property securing a Non Serviced Whole Loan acquired under the related Non-Serviced PSA; (iv) all revenues received in respect of any REO Property (to the extent of the Trust’s interest therein); (v) the Master Servicer’s, the Special Servicer’s, the Certificate Administrator’s and the Trustee’s rights under the insurance policies with respect to the Mortgage Loans and the Trust Subordinate Companion Loans required to be maintained pursuant to the Pooling and Servicing Agreement and any proceeds thereof (to the extent of the Trust’s interest therein); (vi) any Assignment of Leases and any security agreements (to the extent of the Trust’s interest therein); (vii) any letters of credit, indemnities, guaranties or lease enhancement policies given as additional security for any related Mortgage Loans or Trust Subordinate Companion Loans (to the extent of the Trust’s interest therein); (viii) all assets deposited in the Loss of Value Reserve Fund and the Servicing Accounts (to the extent of the Trust’s interest therein), amounts on deposit in the Collection Account (to the extent of the Trust’s interest therein), the Lower-Tier REMIC Distribution Account, the Upper-Tier REMIC Distribution Account, the Trust Subordinate Companion Loan REMIC Distribution Accounts, the Regular Interest Distribution Account, the Excess Interest Distribution Account, the Interest Reserve Account, the Gain-on-Sale Reserve Account (to the extent of the Trust’s interest therein) and any REO Account (to the extent of the Trust’s interest therein), including any reinvestment income, as applicable; (ix) any Environmental Indemnity Agreements (to the extent of the Trust’s interest therein); (x) the rights and remedies of the Depositor under each Mortgage Loan Purchase Agreement (to the extent transferred to the Trustee); (xi) the Lower-Tier Regular Interests; (xii) the Trust Subordinate Companion Loan REMIC Regular Interests; and (xiii) the proceeds of the foregoing (other than any interest earned on deposits in the lock-box accounts, cash collateral accounts, escrow accounts and any reserve accounts, to the extent such interest belongs to the related Mortgagor).

This Certificate does not purport to summarize the Pooling and Servicing Agreement, and reference is made to the Pooling and Servicing Agreement for the interests, rights, benefits, obligations and duties evidenced hereby, and the limitations thereon, and the rights, duties and immunities of the Certificate Administrator and Trustee.

As provided in the Pooling and Servicing Agreement, subject to certain restrictions on transfer set forth therein, upon surrender for registration of transfer of any Certificate, the Certificate Administrator shall execute, authenticate and deliver, in the name of the designated transferee or transferees, one or more new Certificates in authorized denominations, in like aggregate interest and of the same Class.

A-21-8

(vi) to revise or add any other provisions with respect to matters or questions arising under the Pooling and Servicing Agreement or any other change; provided that the required action shall not adversely affect in any material respect the interests of any Certificateholder (including, for the avoidance of doubt, any Holder of a VRR Interest, a Y&L Towers VRR Interest or a Standard Highline VRR Interest) or any holder of a Serviced Pari Passu Companion Loan not consenting to such revision or addition, as evidenced in writing by an Opinion of Counsel, at the expense of the party requesting such amendment or as evidenced by a Rating Agency Confirmation from each of the Rating Agencies with respect to such amendment or supplement and confirmation of the applicable rating agencies that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings of any class of Serviced Companion Loan Securities, if any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement);

(ix) to modify the procedures of the Pooling and Servicing Agreement relating to compliance with Rule 17g-5 of the Exchange Act; provided that such amendment shall not adversely affect in any material respects the interests of any Certificateholders (including, for the avoidance of doubt, any Holders of a VRR Interest, a Y&L Towers VRR Interest or a Standard Highline VRR Interest), as evidenced by (x) an Opinion of Counsel or (y) if any Certificate is then rated, receipt of Rating Agency Confirmation from each Rating Agency rating such Certificates; and provided, further, that the Certificate Administrator shall give notice of any such amendment to the 17g-5 Information Provider for posting to the 17g-5 Information Provider’s Website pursuant to Section 3.13(c) of the Pooling and Servicing Agreement and the Certificate Administrator shall post such notice to the Certificate Administrator’s Website;

Notwithstanding the foregoing, no such amendment (A) may change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations of any Mortgage Loan Seller under any Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller or (B) may materially and adversely affect the holders of a Companion Loan without such Companion Holder’s consent.

(ii) reduce the aforesaid percentage of Certificates of any Class the Holders of which are required to consent to any such amendment or remove the requirement to obtain consent of any Companion Holder or Holder of Loan-Specific Certificates, in any such case, without the consent of the Holders of all Certificates of such Class then-outstanding or such Companion Holders, as applicable; or

(iii) adversely affect the Voting Rights of any Class of Certificates without the consent of the Holders of all Certificates of such Class then outstanding; or

(iv) change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations of any Mortgage Loan Seller under such Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller; or

(v) amend the Servicing Standard without the consent of 100% of the Certificateholders or receipt of Rating Agency Confirmation from each Rating Agency and confirmation of the applicable rating agencies that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings of any Serviced Companion Loan Securities, if any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement) and, if required under the related Intercreditor Agreement, the consent of the holder of any AB Subordinate Companion Loan for each Serviced AB Whole Loan.

Notwithstanding the foregoing, none of the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Depositor, the Master Servicer nor the Special Servicer will be required to consent to any amendment to the Pooling and Servicing Agreement without having first received an Opinion of Counsel (at the Trust’s expense) to the

A-21-11

effect that such amendment is permitted under the Pooling and Servicing Agreement, that all conditions precedent have been satisfied and that such amendment or the exercise of any power granted to the Master Servicer, the Special Servicer, the Depositor, the Trustee, the Certificate Administrator, the Operating Advisor, the Asset Representations Reviewer or any other specified person in accordance with such amendment will not result in the imposition of a tax on any portion of the Trust Fund or any Trust REMIC, or cause any Trust REMIC to fail to qualify as a REMIC or cause the Grantor Trust to fail to qualify as a grantor trust under the relevant provisions of the Code.

The Holders of the majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates may, in that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the Certificate Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage Loans (and all property acquired through exercise of remedies in respect of any related Mortgage Loan), the Trust Subordinate Companion Loans and the Trust’s portion of each REO Property remaining in the Trust Fund, and thereby effect termination of the Trust and early retirement of the then-outstanding Certificates, only on or after the first Distribution Date on which the aggregate Stated Principal Balances of the Mortgage Loans, the Trust Subordinate Companion Loans and the portion of any REO Loans held by the Trust is less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage Loans (solely for the purposes of this calculation, if such right is being exercised after December 2027 and the 237 East Fordham Road Mortgage Loan is still an asset of the Trust, then such Mortgage Loan will be excluded from the then-aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate Companion Loans and from the aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate Companion Loans as of the Cut-off Date) as set forth in the Pooling and Servicing Agreement.

Following the date on which the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class A-S, Class X-A, Class X-B, Class X-E, Class B and Class C Regular Interests have been reduced to zero (and provided that there is only one Holder (or multiple Holders acting in unanimity) of the then-outstanding Certificates (other than the Class Z and Class R Certificates)), the Sole Certificateholder shall have the right, with the consent of the Master Servicer, to exchange all of its Certificates (other than the Class Z and Class R Certificates) together with the payment or deemed payment of the Termination Purchase Amount for all of the Mortgage Loans, the Trust Subordinate Companion Loans and each REO Property remaining in the Trust Fund pursuant to the terms of the Pooling and Servicing Agreement.

The obligations created by the Pooling and Servicing Agreement and the Trust created thereby (other than the obligation of the Certificate Administrator to make payments to Certificateholders as provided for in the Pooling and Servicing Agreement), shall terminate upon reduction of the Certificate Balances of all the Certificates to zero (including, without limitation, any such final payment resulting from a termination of the Trust due to a sale of its property) pursuant to the terms of the Pooling and Servicing Agreement. In no event, however, will the Trust created by the Pooling and Servicing Agreement continue beyond the expiration of 21 years from the death of the last survivor of the descendants of Joseph P. Kennedy, the late Ambassador of the United States to the Court of St. James, living on the date hereof.

subordinate companion loans (the “Trust Subordinate Companion Loans”) held in trust by the Trustee and serviced by the Master Servicer. The Trust Fund was created, and the Mortgage Loans and the Trust Subordinate Companion Loans are to be serviced, pursuant to the Pooling and Servicing Agreement (as defined below). The Holder of this Certificate, by virtue of the acceptance hereof, assents to the terms, provisions and conditions of the Pooling and Servicing Agreement and is bound thereby. In the event that there is any conflict between any provision of this Certificate and any provision of the Pooling and Servicing Agreement, such provision of this Certificate shall be superseded to the extent of such inconsistency. Also issued under the Pooling and Servicing Agreement are the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class X-A, Class X-B, Class X-E, Class A-S, Class B, Class C, Class D, Class E, Class F, Class NR, Class V1-A, Class V1-B, Class V1-D, Class V1-F, Class V1-Z, Class V2-A, Class V2-Z, Class UES-A, Class UES-B, Class UES-C, Class UES-D, Class UES-X, Class STN-A, Class STN-B, Class STN-X, Class STN-C, Class V1-UESA, Class V1-UESD, Class V2-UES, Class V1-STNA, Class V1-STNC, Class V2-STN, Class R and Class Z Certificates (together with the Class V1-E Certificates, the “Certificates”; the Holders of Certificates are collectively referred to herein as “Certificateholders”).

This Certificate is issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of November 1, 2017 (the “Pooling and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities Corp., as Depositor, Wells Fargo Bank, National Association, as Certificate Administrator and as Trustee, Park Bridge Lender Services LLC, as Operating Advisor and as Asset Representations Reviewer, KeyBank National Association, as Master Servicer, and CWCapital Asset Management LLC, as Special Servicer. To the extent not defined herein, capitalized terms used herein shall have the meanings assigned thereto in the Pooling and Servicing Agreement.

This Certificate represents beneficial ownership of multiple “regular interests” in a “real estate mortgage investment conduit,” as those terms are defined, respectively, in Sections 860G(a)(1) and 860D of the Internal Revenue Code of 1986, as amended.

The Certificate Administrator makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates, the Mortgage Loans or the Trust Subordinate Companion Loans and has executed this Certificate in its limited capacity as Certificate Administrator under the Pooling and Servicing Agreement.

Pursuant to the terms of the Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution on any Certificate), on the 4th Business Day following the determination date of each month, commencing in December 2017 (each such date, a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related Record Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this Certificate) of that portion of the aggregate amount of principal and interest then distributable, if any, allocable to the Class V1-E Certificates for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement.

Interest accrued on this Certificate during an Interest Accrual Period, plus the aggregate unpaid Interest Shortfall with respect to this Certificate, if any, will be payable on the related Distribution Date to the extent provided in the Pooling and Servicing Agreement. The “Interest Accrual Period” with respect to any Distribution Date and with respect to the Class V1-E

A-22-5

Certificates is the calendar month immediately preceding the month in which such Distribution Date occurs and is assumed to consist of 30 days.

All distributions (other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons in whose names the Certificates are registered at the close of business on each Record Date, which will be the close of business on the last Business Day of the month immediately preceding the month in which such Distribution Date occurs. Distributions are required to be made (a) by wire transfer of immediately available funds to the account of such Certificateholder at a bank or other entity having appropriate facilities therefor, if such Certificateholder provided the Certificate Administrator with written wiring instructions no less than five Business Days prior to the related Record Date (which wiring instructions may be in the form of a standing order applicable to all subsequent Distribution Dates), or otherwise (b) by check mailed to such Certificateholder at its address in the Certificate Register. The final distribution on each Certificate will be made in like manner, but only upon presentment and surrender of such Certificate at the offices of the Certificate Registrar or such other location specified in the notice to Certificateholders of such final distribution.

Any funds not distributed to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure of such Certificateholders to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited to the account or accounts of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been given pursuant to Section 4.01(l) of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within six months after the time specified in such notice, the Certificate Administrator shall mail a second notice to the remaining non tendering Certificateholders to surrender their Certificates for cancellation in order to receive the final distribution with respect thereto. If within one year after the second notice all such Certificates shall not have been surrendered for cancellation, the Certificate Administrator, directly or through an agent, shall take such steps to contact the remaining non tendering Certificateholders concerning the surrender of their Certificates as it shall deem appropriate and subject to escheatment and other applicable laws. The costs and expenses of holding such funds in trust and of contacting such Certificateholders following the first anniversary of the delivery of such second notice to the non-tendering Certificateholders shall be paid out of such funds. No interest shall accrue or be payable to any Certificateholder on any amount held in trust under the Pooling and Servicing Agreement by the Certificate Administrator as a result of such Certificateholder’s failure to surrender its Certificate(s) for final payment thereof in accordance with Section 4.01(l) of the Pooling and Servicing Agreement.

This Certificate is limited in right of payment to, among other things, certain collections and recoveries in respect of the Mortgage Loans, as more specifically set forth herein and in the Pooling and Servicing Agreement.

As provided in the Pooling and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject to the Pooling and Servicing Agreement (including any Qualified Substitute Mortgage Loan replacing a removed Mortgage Loan) and the Trust Subordinate Companion Loans, together with the Mortgage Files relating thereto (subject to, in the case of a Serviced Whole Loan, the interests of the related Serviced Companion Noteholder in the related Mortgage File); (ii) all scheduled or unscheduled payments on or collections in respect of the Mortgage Loans and the Trust Subordinate Companion Loans due

A-22-6

after the Cut-off Date (or with respect to a Qualified Substitute Mortgage Loan, the Due Date in the month of substitution); (iii) any REO Property (to the extent of the Trust’s interest therein) or the Trust’s beneficial interest in the Mortgaged Property securing a Non Serviced Whole Loan acquired under the related Non-Serviced PSA; (iv) all revenues received in respect of any REO Property (to the extent of the Trust’s interest therein); (v) the Master Servicer’s, the Special Servicer’s, the Certificate Administrator’s and the Trustee’s rights under the insurance policies with respect to the Mortgage Loans and the Trust Subordinate Companion Loans required to be maintained pursuant to the Pooling and Servicing Agreement and any proceeds thereof (to the extent of the Trust’s interest therein); (vi) any Assignment of Leases and any security agreements (to the extent of the Trust’s interest therein); (vii) any letters of credit, indemnities, guaranties or lease enhancement policies given as additional security for any related Mortgage Loans or Trust Subordinate Companion Loans (to the extent of the Trust’s interest therein); (viii) all assets deposited in the Loss of Value Reserve Fund and the Servicing Accounts (to the extent of the Trust’s interest therein), amounts on deposit in the Collection Account (to the extent of the Trust’s interest therein), the Lower-Tier REMIC Distribution Account, the Upper-Tier REMIC Distribution Account, the Trust Subordinate Companion Loan REMIC Distribution Accounts, the Regular Interest Distribution Account, the Excess Interest Distribution Account, the Interest Reserve Account, the Gain-on-Sale Reserve Account (to the extent of the Trust’s interest therein) and any REO Account (to the extent of the Trust’s interest therein), including any reinvestment income, as applicable; (ix) any Environmental Indemnity Agreements (to the extent of the Trust’s interest therein); (x) the rights and remedies of the Depositor under each Mortgage Loan Purchase Agreement (to the extent transferred to the Trustee); (xi) the Lower-Tier Regular Interests; (xii) the Trust Subordinate Companion Loan REMIC Regular Interests; and (xiii) the proceeds of the foregoing (other than any interest earned on deposits in the lock-box accounts, cash collateral accounts, escrow accounts and any reserve accounts, to the extent such interest belongs to the related Mortgagor).

This Certificate does not purport to summarize the Pooling and Servicing Agreement, and reference is made to the Pooling and Servicing Agreement for the interests, rights, benefits, obligations and duties evidenced hereby, and the limitations thereon, and the rights, duties and immunities of the Certificate Administrator and Trustee.

(ix) to modify the procedures of the Pooling and Servicing Agreement relating to compliance with Rule 17g-5 of the Exchange Act; provided that such amendment shall not adversely affect in any material respects the interests of any Certificateholders (including, for the avoidance of doubt, any Holders of a VRR Interest, a Y&L Towers VRR Interest or a Standard Highline VRR Interest), as evidenced by (x) an Opinion of Counsel or (y) if any Certificate is then rated, receipt of Rating Agency Confirmation from each Rating Agency rating such Certificates; and provided, further, that the Certificate Administrator shall give notice of any such amendment to the 17g-5 Information Provider for posting to the 17g-5 Information Provider’s Website pursuant to Section 3.13(c) of the Pooling and Servicing Agreement and the Certificate Administrator shall post such notice to the Certificate Administrator’s Website;

Notwithstanding the foregoing, no such amendment (A) may change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations of any Mortgage Loan Seller under any Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller or (B) may materially and adversely affect the holders of a Companion Loan without such Companion Holder’s consent.

The Pooling and Servicing Agreement may also be amended from time to time by the parties thereto with the consent of the Holders of Certificates of each Class affected by such amendment (including, for the avoidance of doubt, any Holders of the VRR Interest, the Y&L Towers VRR

A-22-11

(i) reduce in any manner the amount of, or delay the timing of, payments received on the Mortgage Loans or the Trust Subordinate Companion Loans that are required to be distributed on a Certificate of any class without the consent of the Holder of the Certificate or which are required to be distributed to a Companion Holder without the consent of such Companion Holder; or

(ii) reduce the aforesaid percentage of Certificates of any Class the Holders of which are required to consent to any such amendment or remove the requirement to obtain consent of any Companion Holder or Holder of Loan-Specific Certificates, in any such case, without the consent of the Holders of all Certificates of such Class then-outstanding or such Companion Holders, as applicable; or

(iii) adversely affect the Voting Rights of any Class of Certificates without the consent of the Holders of all Certificates of such Class then outstanding; or

(iv) change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations of any Mortgage Loan Seller under such Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller; or

(v) amend the Servicing Standard without the consent of 100% of the Certificateholders or receipt of Rating Agency Confirmation from each Rating Agency and confirmation of the applicable rating agencies that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings of any Serviced Companion Loan Securities, if any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement) and, if required under the related Intercreditor Agreement, the consent of the holder of any AB Subordinate Companion Loan for each Serviced AB Whole Loan.

Notwithstanding the foregoing, none of the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Depositor, the Master Servicer nor the Special Servicer will be required to consent to any amendment to the Pooling and Servicing Agreement without having first received an Opinion of Counsel (at the Trust’s expense) to the

A-22-12

effect that such amendment is permitted under the Pooling and Servicing Agreement, that all conditions precedent have been satisfied and that such amendment or the exercise of any power granted to the Master Servicer, the Special Servicer, the Depositor, the Trustee, the Certificate Administrator, the Operating Advisor, the Asset Representations Reviewer or any other specified person in accordance with such amendment will not result in the imposition of a tax on any portion of the Trust Fund or any Trust REMIC, or cause any Trust REMIC to fail to qualify as a REMIC or cause the Grantor Trust to fail to qualify as a grantor trust under the relevant provisions of the Code.

The Holders of the majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates may, in that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the Certificate Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage Loans (and all property acquired through exercise of remedies in respect of any related Mortgage Loan), the Trust Subordinate Companion Loans and the Trust’s portion of each REO Property remaining in the Trust Fund, and thereby effect termination of the Trust and early retirement of the then-outstanding Certificates, only on or after the first Distribution Date on which the aggregate Stated Principal Balances of the Mortgage Loans, the Trust Subordinate Companion Loans and the portion of any REO Loans held by the Trust is less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage Loans (solely for the purposes of this calculation, if such right is being exercised after December 2027 and the 237 East Fordham Road Mortgage Loan is still an asset of the Trust, then such Mortgage Loan will be excluded from the then-aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate Companion Loans and from the aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate Companion Loans as of the Cut-off Date) as set forth in the Pooling and Servicing Agreement.

Following the date on which the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class A-S, Class X-A, Class X-B, Class X-E, Class B and Class C Regular Interests have been reduced to zero (and provided that there is only one Holder (or multiple Holders acting in unanimity) of the then-outstanding Certificates (other than the Class Z and Class R Certificates)), the Sole Certificateholder shall have the right, with the consent of the Master Servicer, to exchange all of its Certificates (other than the Class Z and Class R Certificates) together with the payment or deemed payment of the Termination Purchase Amount for all of the Mortgage Loans, the Trust Subordinate Companion Loans and each REO Property remaining in the Trust Fund pursuant to the terms of the Pooling and Servicing Agreement.

The obligations created by the Pooling and Servicing Agreement and the Trust created thereby (other than the obligation of the Certificate Administrator to make payments to Certificateholders as provided for in the Pooling and Servicing Agreement), shall terminate upon reduction of the Certificate Balances of all the Certificates to zero (including, without limitation, any such final payment resulting from a termination of the Trust due to a sale of its property) pursuant to the terms of the Pooling and Servicing Agreement. In no event, however, will the Trust created by the Pooling and Servicing Agreement continue beyond the expiration of 21 years from the death of the last survivor of the descendants of Joseph P. Kennedy, the late Ambassador of the United States to the Court of St. James, living on the date hereof.

subordinate companion loans (the “Trust Subordinate Companion Loans”) held in trust by the Trustee and serviced by the Master Servicer. The Trust Fund was created, and the Mortgage Loans and the Trust Subordinate Companion Loans are to be serviced, pursuant to the Pooling and Servicing Agreement (as defined below). The Holder of this Certificate, by virtue of the acceptance hereof, assents to the terms, provisions and conditions of the Pooling and Servicing Agreement and is bound thereby. In the event that there is any conflict between any provision of this Certificate and any provision of the Pooling and Servicing Agreement, such provision of this Certificate shall be superseded to the extent of such inconsistency. Also issued under the Pooling and Servicing Agreement are the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class X-A, Class X-B, Class X-E, Class A-S, Class B, Class C, Class D, Class E, Class F, Class NR, Class V1-A, Class V1-B, Class V1-D, Class V1-E, Class V1-Z, Class V2-A, Class V2-Z, Class UES-A, Class UES-B, Class UES-C, Class UES-D, Class UES-X, Class STN-A, Class STN-B, Class STN-X, Class STN-C, Class V1-UESA, Class V1-UESD, Class V2-UES, Class V1-STNA, Class V1-STNC, Class V2-STN, Class R and Class Z Certificates (together with the Class V1-F Certificates, the “Certificates”; the Holders of Certificates are collectively referred to herein as “Certificateholders”).

This Certificate is issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of November 1, 2017 (the “Pooling and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities Corp., as Depositor, Wells Fargo Bank, National Association, as Certificate Administrator and as Trustee, Park Bridge Lender Services LLC, as Operating Advisor and as Asset Representations Reviewer, KeyBank National Association, as Master Servicer, and CWCapital Asset Management LLC, as Special Servicer. To the extent not defined herein, capitalized terms used herein shall have the meanings assigned thereto in the Pooling and Servicing Agreement.

This Certificate represents (i) beneficial ownership of multiple “regular interests” in a “real estate mortgage investment conduit,” as those terms are defined, respectively, in Sections 860G(a)(1) and 860D of the Internal Revenue Code of 1986, as amended and (ii) a beneficial interest in the Excess Interest and proceeds thereof in the Excess Interest Distribution Account.

The Certificate Administrator makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates, the Mortgage Loans and has executed this Certificate in its limited capacity as Certificate Administrator under the Pooling and Servicing Agreement.

Pursuant to the terms of the Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution on any Certificate), on the 4th Business Day following the determination date of each month, commencing in December 2017 (each such date, a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related Record Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this Certificate) of that portion of the aggregate amount of principal and interest then distributable, if any, allocable to the Class V1-F Certificates for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement.

Interest accrued on this Certificate during an Interest Accrual Period, plus the aggregate unpaid Interest Shortfall with respect to this Certificate, if any, will be payable on the related Distribution Date to the extent provided in the Pooling and Servicing Agreement. The “Interest

A-23-5 

Accrual Period” with respect to any Distribution Date and with respect to the Class V1-F Certificates is the calendar month immediately preceding the month in which such Distribution Date occurs and is assumed to consist of 30 days.

All distributions (other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons in whose names the Certificates are registered at the close of business on each Record Date, which will be the close of business on the last Business Day of the month immediately preceding the month in which such Distribution Date occurs. Distributions are required to be made (a) by wire transfer of immediately available funds to the account of such Certificateholder at a bank or other entity having appropriate facilities therefor, if such Certificateholder provided the Certificate Administrator with written wiring instructions no less than five Business Days prior to the related Record Date (which wiring instructions may be in the form of a standing order applicable to all subsequent Distribution Dates), or otherwise (b) by check mailed to such Certificateholder at its address in the Certificate Register. The final distribution on each Certificate will be made in like manner, but only upon presentment and surrender of such Certificate at the offices of the Certificate Registrar or such other location specified in the notice to Certificateholders of such final distribution.

Any funds not distributed to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure of such Certificateholders to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited to the account or accounts of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been given pursuant to Section 4.01(l) of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within six months after the time specified in such notice, the Certificate Administrator shall mail a second notice to the remaining non tendering Certificateholders to surrender their Certificates for cancellation in order to receive the final distribution with respect thereto. If within one year after the second notice all such Certificates shall not have been surrendered for cancellation, the Certificate Administrator, directly or through an agent, shall take such steps to contact the remaining non tendering Certificateholders concerning the surrender of their Certificates as it shall deem appropriate and subject to escheatment and other applicable laws. The costs and expenses of holding such funds in trust and of contacting such Certificateholders following the first anniversary of the delivery of such second notice to the non-tendering Certificateholders shall be paid out of such funds. No interest shall accrue or be payable to any Certificateholder on any amount held in trust under the Pooling and Servicing Agreement by the Certificate Administrator as a result of such Certificateholder’s failure to surrender its Certificate(s) for final payment thereof in accordance with Section 4.01(l) of the Pooling and Servicing Agreement.

This Certificate is limited in right of payment to, among other things, certain collections and recoveries in respect of the Mortgage Loans, as more specifically set forth herein and in the Pooling and Servicing Agreement.

As provided in the Pooling and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject to the Pooling and Servicing Agreement (including any Qualified Substitute Mortgage Loan replacing a removed Mortgage Loan) and the Trust Subordinate Companion Loans, together with the Mortgage Files relating thereto (subject to, in the case of a Serviced Whole Loan, the interests of the related Serviced Companion Noteholder in the related Mortgage File); (ii) all scheduled or unscheduled payments on or

A-23-6 

collections in respect of the Mortgage Loans and the Trust Subordinate Companion Loans due after the Cut-off Date (or with respect to a Qualified Substitute Mortgage Loan, the Due Date in the month of substitution); (iii) any REO Property (to the extent of the Trust’s interest therein) or the Trust’s beneficial interest in the Mortgaged Property securing a Non Serviced Whole Loan acquired under the related Non-Serviced PSA; (iv) all revenues received in respect of any REO Property (to the extent of the Trust’s interest therein); (v) the Master Servicer’s, the Special Servicer’s, the Certificate Administrator’s and the Trustee’s rights under the insurance policies with respect to the Mortgage Loans and the Trust Subordinate Companion Loans required to be maintained pursuant to the Pooling and Servicing Agreement and any proceeds thereof (to the extent of the Trust’s interest therein); (vi) any Assignment of Leases and any security agreements (to the extent of the Trust’s interest therein); (vii) any letters of credit, indemnities, guaranties or lease enhancement policies given as additional security for any related Mortgage Loans or Trust Subordinate Companion Loans (to the extent of the Trust’s interest therein); (viii) all assets deposited in the Loss of Value Reserve Fund and the Servicing Accounts (to the extent of the Trust’s interest therein), amounts on deposit in the Collection Account (to the extent of the Trust’s interest therein), the Lower-Tier REMIC Distribution Account, the Upper-Tier REMIC Distribution Account, the Trust Subordinate Companion Loan REMIC Distribution Accounts, the Regular Interest Distribution Account, the Excess Interest Distribution Account, the Interest Reserve Account, the Gain-on-Sale Reserve Account (to the extent of the Trust’s interest therein) and any REO Account (to the extent of the Trust’s interest therein), including any reinvestment income, as applicable; (ix) any Environmental Indemnity Agreements (to the extent of the Trust’s interest therein); (x) the rights and remedies of the Depositor under each Mortgage Loan Purchase Agreement (to the extent transferred to the Trustee); (xi) the Lower-Tier Regular Interests; (xii) the Trust Subordinate Companion Loan REMIC Regular Interests; and (xiii) the proceeds of the foregoing (other than any interest earned on deposits in the lock-box accounts, cash collateral accounts, escrow accounts and any reserve accounts, to the extent such interest belongs to the related Mortgagor).

Notwithstanding the foregoing, no such amendment (A) may change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations of any Mortgage Loan Seller under any Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller or (B) may materially and adversely affect the holders of a Companion Loan without such Companion Holder’s consent.

Interest or the Standard Highline VRR Interest to the extent any such amendment would adversely affect the rights of such Certificateholders) evidencing in the aggregate not less than a majority of the aggregate Percentage Interests constituting the Class for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of the Pooling and Servicing Agreement or of modifying in any manner the rights of the Holders of Certificates of such Class; provided, however, that no such amendment shall:

(i) reduce in any manner the amount of, or delay the timing of, payments received on the Mortgage Loans or the Trust Subordinate Companion Loans that are required to be distributed on a Certificate of any class without the consent of the Holder of the Certificate or which are required to be distributed to a Companion Holder without the consent of such Companion Holder; or

(ii) reduce the aforesaid percentage of Certificates of any Class the Holders of which are required to consent to any such amendment or remove the requirement to obtain consent of any Companion Holder or Holder of Loan-Specific Certificates, in any such case, without the consent of the Holders of all Certificates of such Class then-outstanding or such Companion Holders, as applicable; or

(iii) adversely affect the Voting Rights of any Class of Certificates without the consent of the Holders of all Certificates of such Class then outstanding; or

(iv) change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations of any Mortgage Loan Seller under such Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller; or

(v) amend the Servicing Standard without the consent of 100% of the Certificateholders or receipt of Rating Agency Confirmation from each Rating Agency and confirmation of the applicable rating agencies that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings of any Serviced Companion Loan Securities, if any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement) and, if required under the related Intercreditor Agreement, the consent of the holder of any AB Subordinate Companion Loan for each Serviced AB Whole Loan.

Notwithstanding the foregoing, none of the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Depositor, the Master Servicer nor the Special Servicer will be required to consent to any amendment to the Pooling and Servicing Agreement without having first received an Opinion of Counsel (at the Trust’s expense) to the

A-23-12 

effect that such amendment is permitted under the Pooling and Servicing Agreement, that all conditions precedent have been satisfied and that such amendment or the exercise of any power granted to the Master Servicer, the Special Servicer, the Depositor, the Trustee, the Certificate Administrator, the Operating Advisor, the Asset Representations Reviewer or any other specified person in accordance with such amendment will not result in the imposition of a tax on any portion of the Trust Fund or any Trust REMIC, or cause any Trust REMIC to fail to qualify as a REMIC or cause the Grantor Trust to fail to qualify as a grantor trust under the relevant provisions of the Code.

The Holders of the majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates may, in that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the Certificate Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage Loans (and all property acquired through exercise of remedies in respect of any related Mortgage Loan), the Trust Subordinate Companion Loans and the Trust’s portion of each REO Property remaining in the Trust Fund, and thereby effect termination of the Trust and early retirement of the then-outstanding Certificates, only on or after the first Distribution Date on which the aggregate Stated Principal Balances of the Mortgage Loans, the Trust Subordinate Companion Loans and the portion of any REO Loans held by the Trust is less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage Loans (solely for the purposes of this calculation, if such right is being exercised after December 2027 and the 237 East Fordham Road Mortgage Loan is still an asset of the Trust, then such Mortgage Loan will be excluded from the then-aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate Companion Loans and from the aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate Companion Loans as of the Cut-off Date) as set forth in the Pooling and Servicing Agreement.

Following the date on which the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class A-S, Class X-A, Class X-B, Class X-E, Class B and Class C Regular Interests have been reduced to zero (and provided that there is only one Holder (or multiple Holders acting in unanimity) of the then-outstanding Certificates (other than the Class Z and Class R Certificates)), the Sole Certificateholder shall have the right, with the consent of the Master Servicer, to exchange all of its Certificates (other than the Class Z and Class R Certificates) together with the payment or deemed payment of the Termination Purchase Amount for all of the Mortgage Loans, the Trust Subordinate Companion Loans and each REO Property remaining in the Trust Fund pursuant to the terms of the Pooling and Servicing Agreement.

The obligations created by the Pooling and Servicing Agreement and the Trust created thereby (other than the obligation of the Certificate Administrator to make payments to Certificateholders as provided for in the Pooling and Servicing Agreement), shall terminate upon reduction of the Certificate Balances of all the Certificates to zero (including, without limitation, any such final payment resulting from a termination of the Trust due to a sale of its property) pursuant to the terms of the Pooling and Servicing Agreement. In no event, however, will the Trust created by the Pooling and Servicing Agreement continue beyond the expiration of 21 years from the death of the last survivor of the descendants of Joseph P. Kennedy, the late Ambassador of the United States to the Court of St. James, living on the date hereof.

Trustee and serviced by the Master Servicer. The Trust Fund was created, and the Mortgage Loans and the Trust Subordinate Companion Loans are to be serviced, pursuant to the Pooling and Servicing Agreement (as defined below). The Holder of this Certificate, by virtue of the acceptance hereof, assents to the terms, provisions and conditions of the Pooling and Servicing Agreement and is bound thereby. In the event that there is any conflict between any provision of this Certificate and any provision of the Pooling and Servicing Agreement, such provision of this Certificate shall be superseded to the extent of such inconsistency. Also issued under the Pooling and Servicing Agreement are the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class X-A, Class X-B, Class X-E, Class A-S, Class B, Class C, Class D, Class E, Class F, Class NR, Class V1-A, Class V1-B, Class V1-D, Class V1-E, Class V1-F, Class V2-A, Class V2-Z, Class UES-A, Class UES-B, Class UES-C, Class UES-D, Class UES-X, Class STN-A, Class STN-B, Class STN-X, Class STN-C, Class V1-UESA, Class V1-UESD, Class V2-UES, Class V1-STNA, Class V1-STNC, Class V2-STN, Class R and Class Z Certificates (together with the Class V1-Z Certificates, the “Certificates”; the Holders of Certificates are collectively referred to herein as “Certificateholders”).

This Certificate is issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of November 1, 2017 (the “Pooling and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities Corp., as Depositor, Wells Fargo Bank, National Association, as Certificate Administrator and as Trustee, Park Bridge Lender Services LLC, as Operating Advisor and as Asset Representations Reviewer, KeyBank National Association, as Master Servicer, and CWCapital Asset Management LLC, as Special Servicer. To the extent not defined herein, capitalized terms used herein shall have the meanings assigned thereto in the Pooling and Servicing Agreement.

The Certificate Administrator makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates, the Mortgage Loans or the Trust Subordinate Companion Loans and has executed this Certificate in its limited capacity as Certificate Administrator under the Pooling and Servicing Agreement.

Pursuant to the terms of the Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution on any Certificate), on the 4th Business Day following the determination date of each month, commencing in December 2017 (each such date, a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related Record Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this Certificate) of that portion of the aggregate amount of principal and interest then distributable, if any, allocable to the Class V1-Z Certificates for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement.

Interest accrued on this Certificate during an Interest Accrual Period, plus the aggregate unpaid Interest Shortfall with respect to this Certificate, if any, will be payable on the related Distribution Date to the extent provided in the Pooling and Servicing Agreement. The “Interest Accrual Period” with respect to any Distribution Date and with respect to the Class V1-Z Certificates is the calendar month immediately preceding the month in which such Distribution Date occurs and is assumed to consist of 30 days.

All distributions (other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons in whose names the Certificates are registered at the

A-24-4 

close of business on each Record Date, which will be the close of business on the last Business Day of the month immediately preceding the month in which such Distribution Date occurs. Distributions are required to be made (a) by wire transfer of immediately available funds to the account of such Certificateholder at a bank or other entity having appropriate facilities therefor, if such Certificateholder provided the Certificate Administrator with written wiring instructions no less than five Business Days prior to the related Record Date (which wiring instructions may be in the form of a standing order applicable to all subsequent Distribution Dates), or otherwise (b) by check mailed to such Certificateholder at its address in the Certificate Register. The final distribution on each Certificate will be made in like manner, but only upon presentment and surrender of such Certificate at the offices of the Certificate Registrar or such other location specified in the notice to Certificateholders of such final distribution.

Any funds not distributed to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure of such Certificateholders to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited to the account or accounts of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been given pursuant to Section 4.01(l) of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within six months after the time specified in such notice, the Certificate Administrator shall mail a second notice to the remaining non tendering Certificateholders to surrender their Certificates for cancellation in order to receive the final distribution with respect thereto. If within one year after the second notice all such Certificates shall not have been surrendered for cancellation, the Certificate Administrator, directly or through an agent, shall take such steps to contact the remaining non tendering Certificateholders concerning the surrender of their Certificates as it shall deem appropriate and subject to escheatment and other applicable laws. The costs and expenses of holding such funds in trust and of contacting such Certificateholders following the first anniversary of the delivery of such second notice to the non-tendering Certificateholders shall be paid out of such funds. No interest shall accrue or be payable to any Certificateholder on any amount held in trust under the Pooling and Servicing Agreement by the Certificate Administrator as a result of such Certificateholder’s failure to surrender its Certificate(s) for final payment thereof in accordance with Section 4.01(l) of the Pooling and Servicing Agreement.

This Certificate is limited in right of payment to, among other things, certain collections and recoveries in respect of the Mortgage Loans, as more specifically set forth herein and in the Pooling and Servicing Agreement.

As provided in the Pooling and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject to the Pooling and Servicing Agreement (including any Qualified Substitute Mortgage Loan replacing a removed Mortgage Loan) and the Trust Subordinate Companion Loans, together with the Mortgage Files relating thereto (subject to, in the case of a Serviced Whole Loan, the interests of the related Serviced Companion Noteholder in the related Mortgage File); (ii) all scheduled or unscheduled payments on or collections in respect of the Mortgage Loans and the Trust Subordinate Companion Loans due after the Cut-off Date (or with respect to a Qualified Substitute Mortgage Loan, the Due Date in the month of substitution); (iii) any REO Property (to the extent of the Trust’s interest therein) or the Trust’s beneficial interest in the Mortgaged Property securing a Non Serviced Whole Loan acquired under the related Non-Serviced PSA; (iv) all revenues received in respect of any REO

A-24-5 

Property (to the extent of the Trust’s interest therein); (v) the Master Servicer’s, the Special Servicer’s, the Certificate Administrator’s and the Trustee’s rights under the insurance policies with respect to the Mortgage Loans and the Trust Subordinate Companion Loans required to be maintained pursuant to the Pooling and Servicing Agreement and any proceeds thereof (to the extent of the Trust’s interest therein); (vi) any Assignment of Leases and any security agreements (to the extent of the Trust’s interest therein); (vii) any letters of credit, indemnities, guaranties or lease enhancement policies given as additional security for any related Mortgage Loans or Trust Subordinate Companion Loans (to the extent of the Trust’s interest therein); (viii) all assets deposited in the Loss of Value Reserve Fund and the Servicing Accounts (to the extent of the Trust’s interest therein), amounts on deposit in the Collection Account (to the extent of the Trust’s interest therein), the Lower-Tier REMIC Distribution Account, the Upper-Tier REMIC Distribution Account, the Trust Subordinate Companion Loan REMIC Distribution Accounts, the Regular Interest Distribution Account, the Excess Interest Distribution Account, the Interest Reserve Account, the Gain-on-Sale Reserve Account (to the extent of the Trust’s interest therein) and any REO Account (to the extent of the Trust’s interest therein), including any reinvestment income, as applicable; (ix) any Environmental Indemnity Agreements (to the extent of the Trust’s interest therein); (x) the rights and remedies of the Depositor under each Mortgage Loan Purchase Agreement (to the extent transferred to the Trustee); (xi) the Lower-Tier Regular Interests; (xii) the Trust Subordinate Companion Loan REMIC Regular Interests; and (xiii) the proceeds of the foregoing (other than any interest earned on deposits in the lock-box accounts, cash collateral accounts, escrow accounts and any reserve accounts, to the extent such interest belongs to the related Mortgagor).

This Certificate does not purport to summarize the Pooling and Servicing Agreement, and reference is made to the Pooling and Servicing Agreement for the interests, rights, benefits, obligations and duties evidenced hereby, and the limitations thereon, and the rights, duties and immunities of the Certificate Administrator and Trustee.

As provided in the Pooling and Servicing Agreement, subject to certain restrictions on transfer set forth therein, upon surrender for registration of transfer of any Certificate, the Certificate Administrator shall execute, authenticate and deliver, in the name of the designated transferee or transferees, one or more new Certificates in authorized denominations, in like aggregate interest and of the same Class.

Prior to due presentation of this Certificate for registration of transfer, the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Certificate Registrar, and any agent of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate Registrar may treat the Person in whose name any Certificate is registered as the owner of such Certificate for the purpose of receiving distributions as provided in the Pooling and Servicing Agreement and for all other purposes whatsoever, and none of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Certificate Registrar, or any agent of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate Registrar shall be affected by any notice to the contrary.

any of the Certificateholders (other than the Transferor) to be subject to a federal tax caused by a Transfer to a Person that is a Disqualified Organization or a Non-U.S. Tax Person;

(vi) to revise or add any other provisions with respect to matters or questions arising under the Pooling and Servicing Agreement or any other change; provided that the required action shall not adversely affect in any material respect the interests of any Certificateholder (including, for the avoidance of doubt, any Holder of a VRR Interest, a Y&L Towers VRR Interest or a Standard Highline VRR Interest) or any holder of a Serviced Pari Passu Companion Loan not consenting to such revision or addition, as evidenced in writing by an Opinion of Counsel, at the expense of the party requesting such amendment or as evidenced by a Rating Agency Confirmation from each of the Rating Agencies with respect to such amendment or supplement and confirmation of the applicable rating agencies that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings of any class of Serviced Companion Loan Securities, if any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement);

(viii) to modify the provisions of Sections 3.05 and 3.17 of the Pooling and Servicing Agreement (with respect to reimbursement of Nonrecoverable Advances and Workout-Delayed Reimbursement Amounts) if (a) the Depositor, the Master Servicer, the Trustee and, for so long as a Control Termination Event has not occurred and is not continuing and, with respect to any Mortgage Loans other than any Excluded Loan, as to the Directing Holder or, in the case of the Directing Certificateholder, the Holder of a majority of the Controlling Class, the Directing Holder,

A-24-8

(ix) to modify the procedures of the Pooling and Servicing Agreement relating to compliance with Rule 17g-5 of the Exchange Act; provided that such amendment shall not adversely affect in any material respects the interests of any Certificateholders (including, for the avoidance of doubt, any Holders of a VRR Interest, a Y&L Towers VRR Interest or a Standard Highline VRR Interest), as evidenced by (x) an Opinion of Counsel or (y) if any Certificate is then rated, receipt of Rating Agency Confirmation from each Rating Agency rating such Certificates; and provided, further, that the Certificate Administrator shall give notice of any such amendment to the 17g-5 Information Provider for posting to the 17g-5 Information Provider’s Website pursuant to Section 3.13(c) of the Pooling and Servicing Agreement and the Certificate Administrator shall post such notice to the Certificate Administrator’s Website;

Notwithstanding the foregoing, no such amendment (A) may change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations of any Mortgage Loan Seller under any Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller or (B) may materially and adversely affect the holders of a Companion Loan without such Companion Holder’s consent.

A-24-9 

The Pooling and Servicing Agreement may also be amended from time to time by the parties thereto with the consent of the Holders of Certificates of each Class affected by such amendment (including, for the avoidance of doubt, any Holders of the VRR Interest, the Y&L Towers VRR Interest or the Standard Highline VRR Interest to the extent any such amendment would adversely affect the rights of such Certificateholders) evidencing in the aggregate not less than a majority of the aggregate Percentage Interests constituting the Class for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of the Pooling and Servicing Agreement or of modifying in any manner the rights of the Holders of Certificates of such Class; provided, however, that no such amendment shall:

(i) reduce in any manner the amount of, or delay the timing of, payments received on the Mortgage Loans or the Trust Subordinate Companion Loans that are required to be distributed on a Certificate of any class without the consent of the Holder of the Certificate or which are required to be distributed to a Companion Holder without the consent of such Companion Holder; or

Notwithstanding the foregoing, none of the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Depositor, the Master Servicer nor the Special Servicer will be required to consent to any amendment to the Pooling and Servicing Agreement without having first received an Opinion of Counsel (at the Trust’s expense) to the effect that such amendment is permitted under the Pooling and Servicing Agreement, that all conditions precedent have been satisfied and that such amendment or the exercise of any power granted to the Master Servicer, the Special Servicer, the Depositor, the Trustee, the Certificate Administrator, the Operating Advisor, the Asset Representations Reviewer or any other specified person in accordance with such amendment will not result in the imposition of a tax on any portion of the Trust Fund or any Trust REMIC, or cause any Trust REMIC to fail to qualify as a REMIC or cause the Grantor Trust to fail to qualify as a grantor trust under the relevant provisions of the Code.

The Holders of the majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates may, in that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the Certificate Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage Loans (and all property acquired through exercise of remedies in respect of any related Mortgage Loan), the Trust Subordinate Companion Loans and the Trust’s portion of each REO Property remaining in the Trust Fund, and thereby effect termination of the Trust and early retirement of the then-outstanding Certificates, only on or after the first Distribution Date on which the aggregate Stated Principal Balances of the Mortgage Loans, the Trust Subordinate Companion Loans and the portion of any REO Loans held by the Trust is less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage Loans (solely for the purposes of this calculation, if such right is being exercised after December 2027 and the 237 East Fordham Road Mortgage Loan is still an asset of the Trust, then such Mortgage Loan will be excluded from the then-aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate Companion Loans and from the aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate Companion Loans as of the Cut-off Date) as set forth in the Pooling and Servicing Agreement.

Following the date on which the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class A-S, Class X-A, Class X-B, Class X-E, Class B and Class C Regular Interests have been reduced to zero (and provided that there is only one Holder (or multiple Holders acting in unanimity) of the then-outstanding Certificates (other than the Class Z and Class R Certificates)), the Sole Certificateholder shall have the right, with the consent of the Master Servicer, to exchange all of its Certificates (other than the Class Z and Class R Certificates) together with the payment or deemed payment of the Termination Purchase Amount for all of the Mortgage Loans, the Trust Subordinate Companion Loans and each REO Property remaining in the Trust Fund pursuant to the terms of the Pooling and Servicing Agreement.

The obligations created by the Pooling and Servicing Agreement and the Trust created thereby (other than the obligation of the Certificate Administrator to make payments to Certificateholders as provided for in the Pooling and Servicing Agreement), shall terminate upon reduction of the Certificate Balances of all the Certificates to zero (including, without limitation, any such final payment resulting from a termination of the Trust due to a sale of its property) pursuant to the terms of the Pooling and Servicing Agreement. In no event, however, will the

Trust created by the Pooling and Servicing Agreement continue beyond the expiration of 21 years from the death of the last survivor of the descendants of Joseph P. Kennedy, the late Ambassador of the United States to the Court of St. James, living on the date hereof.

Unless the certificate of authentication hereon has been executed by the Authenticating Agent, by manual signature, this Certificate shall not be entitled to any benefit under the Pooling and Servicing Agreement or be valid for any purpose. The Certificate Registrar has executed this Certificate on behalf of the Trust as Certificate Registrar under the Pooling and Servicing Agreement and makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates, the Mortgage Loans or the Trust Subordinate Companion Loans.

Trustee and serviced by the Master Servicer. The Trust Fund was created, and the Mortgage Loans and the Trust Subordinate Companion Loans are to be serviced, pursuant to the Pooling and Servicing Agreement (as defined below). The Holder of this Certificate, by virtue of the acceptance hereof, assents to the terms, provisions and conditions of the Pooling and Servicing Agreement and is bound thereby. In the event that there is any conflict between any provision of this Certificate and any provision of the Pooling and Servicing Agreement, such provision of this Certificate shall be superseded to the extent of such inconsistency. Also issued under the Pooling and Servicing Agreement are the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class X-A, Class X-B, Class X-E, Class A-S, Class B, Class C, Class D, Class E, Class F, Class NR, Class V1-A, Class V1-B, Class V1-D, Class V1-E, Class V1-F, Class V1-Z, Class V2-Z, Class UES-A, Class UES-B, Class UES-C, Class UES-D, Class UES-X, Class STN-A, Class STN-B, Class STN-X, Class STN-C, Class V1-UESA, Class V1-UESD, Class V2-UES, Class V1-STNA, Class V1-STNC, Class V2-STN, Class R and Class Z Certificates (together with the Class V2-A Certificates, the “Certificates”; the Holders of Certificates are collectively referred to herein as “Certificateholders”).

This Certificate is issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of November 1, 2017 (the “Pooling and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities Corp., as Depositor, Wells Fargo Bank, National Association, as Certificate Administrator and as Trustee, Park Bridge Lender Services LLC, as Operating Advisor and as Asset Representations Reviewer, KeyBank National Association, as Master Servicer, and CWCapital Asset Management LLC, as Special Servicer. To the extent not defined herein, capitalized terms used herein shall have the meanings assigned thereto in the Pooling and Servicing Agreement.

This Certificate represents beneficial ownership of multiple “regular interests” in a “real estate mortgage investment conduit,” as those terms are defined, respectively, in Sections 860G(a)(1) and 860D of the Internal Revenue Code of 1986, as amended.

The Certificate Administrator makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates, the Mortgage Loans or the Trust Subordinate Companion Loans and has executed this Certificate in its limited capacity as Certificate Administrator under the Pooling and Servicing Agreement.

Pursuant to the terms of the Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution on any Certificate), on the 4th Business Day following the determination date of each month, commencing in December 2017 (each such date, a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related Record Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this Certificate) of that portion of the aggregate amount of principal and interest then distributable, if any, allocable to the Class V2-A Certificates for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement. Holders of this Certificate may be entitled to Yield Maintenance Charges, as provided in the Pooling and Servicing Agreement.

Interest accrued on this Certificate during an Interest Accrual Period, plus the aggregate unpaid Interest Shortfall with respect to this Certificate, if any, will be payable on the related Distribution Date to the extent provided in the Pooling and Servicing Agreement. The “Interest

A-25-5 

Accrual Period” with respect to any Distribution Date and with respect to the Class V2-A Certificates is the calendar month immediately preceding the month in which such Distribution Date occurs and is assumed to consist of 30 days.

All distributions (other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons in whose names the Certificates are registered at the close of business on each Record Date, which will be the close of business on the last Business Day of the month immediately preceding the month in which such Distribution Date occurs. Distributions are required to be made (a) by wire transfer of immediately available funds to the account of such Certificateholder at a bank or other entity having appropriate facilities therefor, if such Certificateholder provided the Certificate Administrator with written wiring instructions no less than five Business Days prior to the related Record Date (which wiring instructions may be in the form of a standing order applicable to all subsequent Distribution Dates), or otherwise (b) by check mailed to such Certificateholder at its address in the Certificate Register. The final distribution on each Certificate will be made in like manner, but only upon presentment and surrender of such Certificate at the offices of the Certificate Registrar or such other location specified in the notice to Certificateholders of such final distribution.

Any funds not distributed to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure of such Certificateholders to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited to the account or accounts of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been given pursuant to Section 4.01(l) of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within six months after the time specified in such notice, the Certificate Administrator shall mail a second notice to the remaining non tendering Certificateholders to surrender their Certificates for cancellation in order to receive the final distribution with respect thereto. If within one year after the second notice all such Certificates shall not have been surrendered for cancellation, the Certificate Administrator, directly or through an agent, shall take such steps to contact the remaining non tendering Certificateholders concerning the surrender of their Certificates as it shall deem appropriate and subject to escheatment and other applicable laws. The costs and expenses of holding such funds in trust and of contacting such Certificateholders following the first anniversary of the delivery of such second notice to the non-tendering Certificateholders shall be paid out of such funds. No interest shall accrue or be payable to any Certificateholder on any amount held in trust under the Pooling and Servicing Agreement by the Certificate Administrator as a result of such Certificateholder’s failure to surrender its Certificate(s) for final payment thereof in accordance with Section 4.01(l) of the Pooling and Servicing Agreement.

This Certificate is limited in right of payment to, among other things, certain collections and recoveries in respect of the Mortgage Loans, as more specifically set forth herein and in the Pooling and Servicing Agreement.

As provided in the Pooling and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject to the Pooling and Servicing Agreement (including any Qualified Substitute Mortgage Loan replacing a removed Mortgage Loan) and the Trust Subordinate Companion Loans, together with the Mortgage Files relating thereto (subject to, in the case of a Serviced Whole Loan, the interests of the related Serviced Companion Noteholder in the related Mortgage File); (ii) all scheduled or unscheduled payments on or

A-25-6 

collections in respect of the Mortgage Loans and the Trust Subordinate Companion Loans due after the Cut-off Date (or with respect to a Qualified Substitute Mortgage Loan, the Due Date in the month of substitution); (iii) any REO Property (to the extent of the Trust’s interest therein) or the Trust’s beneficial interest in the Mortgaged Property securing a Non Serviced Whole Loan acquired under the related Non-Serviced PSA; (iv) all revenues received in respect of any REO Property (to the extent of the Trust’s interest therein); (v) the Master Servicer’s, the Special Servicer’s, the Certificate Administrator’s and the Trustee’s rights under the insurance policies with respect to the Mortgage Loans and the Trust Subordinate Companion Loans required to be maintained pursuant to the Pooling and Servicing Agreement and any proceeds thereof (to the extent of the Trust’s interest therein); (vi) any Assignment of Leases and any security agreements (to the extent of the Trust’s interest therein); (vii) any letters of credit, indemnities, guaranties or lease enhancement policies given as additional security for any related Mortgage Loans or Trust Subordinate Companion Loans (to the extent of the Trust’s interest therein); (viii) all assets deposited in the Loss of Value Reserve Fund and the Servicing Accounts (to the extent of the Trust’s interest therein), amounts on deposit in the Collection Account (to the extent of the Trust’s interest therein), the Lower-Tier REMIC Distribution Account, the Upper-Tier REMIC Distribution Account, the Trust Subordinate Companion Loan REMIC Distribution Accounts, the Regular Interest Distribution Account, the Excess Interest Distribution Account, the Interest Reserve Account, the Gain-on-Sale Reserve Account (to the extent of the Trust’s interest therein) and any REO Account (to the extent of the Trust’s interest therein), including any reinvestment income, as applicable; (ix) any Environmental Indemnity Agreements (to the extent of the Trust’s interest therein); (x) the rights and remedies of the Depositor under each Mortgage Loan Purchase Agreement (to the extent transferred to the Trustee); (xi) the Lower-Tier Regular Interests; (xii) the Trust Subordinate Companion Loan REMIC Regular Interests; and (xiii) the proceeds of the foregoing (other than any interest earned on deposits in the lock-box accounts, cash collateral accounts, escrow accounts and any reserve accounts, to the extent such interest belongs to the related Mortgagor).

This Certificate does not purport to summarize the Pooling and Servicing Agreement, and reference is made to the Pooling and Servicing Agreement for the interests, rights, benefits, obligations and duties evidenced hereby, and the limitations thereon, and the rights, duties and immunities of the Certificate Administrator and Trustee.

As provided in the Pooling and Servicing Agreement, subject to certain restrictions on transfer set forth therein, upon surrender for registration of transfer of any Certificate, the Certificate Administrator shall execute, authenticate and deliver, in the name of the designated transferee or transferees, one or more new Certificates in authorized denominations, in like aggregate interest and of the same Class.

Notwithstanding the foregoing, no such amendment (A) may change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations of any Mortgage Loan Seller under any Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller or (B) may materially and adversely affect the holders of a Companion Loan without such Companion Holder’s consent.

(i) reduce in any manner the amount of, or delay the timing of, payments received on the Mortgage Loans or the Trust Subordinate Companion Loans that are required to be distributed on a Certificate of any class without the consent of the Holder of the Certificate or which are required to be distributed to a Companion Holder without the consent of such Companion Holder; or

(ii) reduce the aforesaid percentage of Certificates of any Class the Holders of which are required to consent to any such amendment or remove the requirement to obtain consent of any Companion Holder or Holder of Loan-Specific Certificates, in any such case, without the consent of the Holders of all Certificates of such Class then-outstanding or such Companion Holders, as applicable; or

(v) amend the Servicing Standard without the consent of 100% of the Certificateholders or receipt of Rating Agency Confirmation from each Rating Agency and confirmation of the applicable rating agencies that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings of any Serviced Companion Loan Securities, if any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement) and, if required under the related Intercreditor Agreement, the consent of the holder of any AB Subordinate Companion Loan for each Serviced AB Whole Loan.

Notwithstanding the foregoing, none of the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Depositor, the Master Servicer nor the Special Servicer will be required to consent to any amendment to the Pooling and Servicing Agreement without having first received an Opinion of Counsel (at the Trust’s expense) to the

A-25-12 

effect that such amendment is permitted under the Pooling and Servicing Agreement, that all conditions precedent have been satisfied and that such amendment or the exercise of any power granted to the Master Servicer, the Special Servicer, the Depositor, the Trustee, the Certificate Administrator, the Operating Advisor, the Asset Representations Reviewer or any other specified person in accordance with such amendment will not result in the imposition of a tax on any portion of the Trust Fund or any Trust REMIC, or cause any Trust REMIC to fail to qualify as a REMIC or cause the Grantor Trust to fail to qualify as a grantor trust under the relevant provisions of the Code.

The Holders of the majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates may, in that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the Certificate Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage Loans (and all property acquired through exercise of remedies in respect of any related Mortgage Loan), the Trust Subordinate Companion Loans and the Trust’s portion of each REO Property remaining in the Trust Fund, and thereby effect termination of the Trust and early retirement of the then-outstanding Certificates, only on or after the first Distribution Date on which the aggregate Stated Principal Balances of the Mortgage Loans, the Trust Subordinate Companion Loans and the portion of any REO Loans held by the Trust is less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage Loans (solely for the purposes of this calculation, if such right is being exercised after December 2027 and the 237 East Fordham Road Mortgage Loan is still an asset of the Trust, then such Mortgage Loan will be excluded from the then-aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate Companion Loans and from the aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate Companion Loans as of the Cut-off Date) as set forth in the Pooling and Servicing Agreement.

Following the date on which the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class A-S, Class X-A, Class X-B, Class X-E, Class B and Class C Regular Interests have been reduced to zero (and provided that there is only one Holder (or multiple Holders acting in unanimity) of the then-outstanding Certificates (other than the Class Z and Class R Certificates)), the Sole Certificateholder shall have the right, with the consent of the Master Servicer, to exchange all of its Certificates (other than the Class Z and Class R Certificates) together with the payment or deemed payment of the Termination Purchase Amount for all of the Mortgage Loans, the Trust Subordinate Companion Loans and each REO Property remaining in the Trust Fund pursuant to the terms of the Pooling and Servicing Agreement.

The obligations created by the Pooling and Servicing Agreement and the Trust created thereby (other than the obligation of the Certificate Administrator to make payments to Certificateholders as provided for in the Pooling and Servicing Agreement), shall terminate upon reduction of the Certificate Balances of all the Certificates to zero (including, without limitation, any such final payment resulting from a termination of the Trust due to a sale of its property) pursuant to the terms of the Pooling and Servicing Agreement. In no event, however, will the Trust created by the Pooling and Servicing Agreement continue beyond the expiration of 21 years from the death of the last survivor of the descendants of Joseph P. Kennedy, the late Ambassador of the United States to the Court of St. James, living on the date hereof.

Trustee and serviced by the Master Servicer. The Trust Fund was created, and the Mortgage Loans and the Trust Subordinate Companion Loans are to be serviced, pursuant to the Pooling and Servicing Agreement (as defined below). The Holder of this Certificate, by virtue of the acceptance hereof, assents to the terms, provisions and conditions of the Pooling and Servicing Agreement and is bound thereby. In the event that there is any conflict between any provision of this Certificate and any provision of the Pooling and Servicing Agreement, such provision of this Certificate shall be superseded to the extent of such inconsistency. Also issued under the Pooling and Servicing Agreement are the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class X-A, Class X-B, Class X-E, Class A-S, Class B, Class C, Class D, Class E, Class F, Class NR, Class V1-A, Class V1-B, Class V1-D, Class V1-E, Class V1-F, Class V1-Z, Class V2-A, Class UES-A, Class UES-B, Class UES-C, Class UES-D, Class UES-X, Class STN-A, Class STN-B, Class STN-X, Class STN-C, Class V1-UESA, Class V1-UESD, Class V2-UES, Class V1-STNA, Class V1-STNC, Class V2-STN, Class R and Class Z Certificates (together with the Class V2-Z Certificates, the “Certificates”; the Holders of Certificates are collectively referred to herein as “Certificateholders”).

This Certificate is issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of November 1, 2017 (the “Pooling and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities Corp., as Depositor, Wells Fargo Bank, National Association, as Certificate Administrator and as Trustee, Park Bridge Lender Services LLC, as Operating Advisor and as Asset Representations Reviewer, KeyBank National Association, as Master Servicer, and CWCapital Asset Management LLC, as Special Servicer. To the extent not defined herein, capitalized terms used herein shall have the meanings assigned thereto in the Pooling and Servicing Agreement.

The Certificate Administrator makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates, the Mortgage Loans or the Trust Subordinate Companion Loans and has executed this Certificate in its limited capacity as Certificate Administrator under the Pooling and Servicing Agreement.

Pursuant to the terms of the Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution on any Certificate), on the 4th Business Day following the determination date of each month, commencing in December 2017 (each such date, a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related Record Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this Certificate) of that portion of the aggregate amount of principal and interest then distributable, if any, allocable to the Class V2-Z Certificates for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement. Holders of this Certificate may be entitled to Yield Maintenance Charges, as provided in the Pooling and Servicing Agreement.

Interest accrued on this Certificate during an Interest Accrual Period, plus the aggregate unpaid Interest Shortfall with respect to this Certificate, if any, will be payable on the related Distribution Date to the extent provided in the Pooling and Servicing Agreement. The “Interest Accrual Period” with respect to any Distribution Date and with respect to the Class V2-Z Certificates is the calendar month immediately preceding the month in which such Distribution Date occurs and is assumed to consist of 30 days.

A-22-4 

All distributions (other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons in whose names the Certificates are registered at the close of business on each Record Date, which will be the close of business on the last Business Day of the month immediately preceding the month in which such Distribution Date occurs. Distributions are required to be made (a) by wire transfer of immediately available funds to the account of such Certificateholder at a bank or other entity having appropriate facilities therefor, if such Certificateholder provided the Certificate Administrator with written wiring instructions no less than five Business Days prior to the related Record Date (which wiring instructions may be in the form of a standing order applicable to all subsequent Distribution Dates), or otherwise (b) by check mailed to such Certificateholder at its address in the Certificate Register. The final distribution on each Certificate will be made in like manner, but only upon presentment and surrender of such Certificate at the offices of the Certificate Registrar or such other location specified in the notice to Certificateholders of such final distribution.

Any funds not distributed to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure of such Certificateholders to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited to the account or accounts of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been given pursuant to Section 4.01(l) of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within six months after the time specified in such notice, the Certificate Administrator shall mail a second notice to the remaining non tendering Certificateholders to surrender their Certificates for cancellation in order to receive the final distribution with respect thereto. If within one year after the second notice all such Certificates shall not have been surrendered for cancellation, the Certificate Administrator, directly or through an agent, shall take such steps to contact the remaining non tendering Certificateholders concerning the surrender of their Certificates as it shall deem appropriate and subject to escheatment and other applicable laws. The costs and expenses of holding such funds in trust and of contacting such Certificateholders following the first anniversary of the delivery of such second notice to the non-tendering Certificateholders shall be paid out of such funds. No interest shall accrue or be payable to any Certificateholder on any amount held in trust under the Pooling and Servicing Agreement by the Certificate Administrator as a result of such Certificateholder’s failure to surrender its Certificate(s) for final payment thereof in accordance with Section 4.01(l) of the Pooling and Servicing Agreement.

This Certificate is limited in right of payment to, among other things, certain collections and recoveries in respect of the Mortgage Loans, as more specifically set forth herein and in the Pooling and Servicing Agreement.

As provided in the Pooling and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject to the Pooling and Servicing Agreement (including any Qualified Substitute Mortgage Loan replacing a removed Mortgage Loan) and the Trust Subordinate Companion Loans, together with the Mortgage Files relating thereto (subject to, in the case of a Serviced Whole Loan, the interests of the related Serviced Companion Noteholder in the related Mortgage File); (ii) all scheduled or unscheduled payments on or collections in respect of the Mortgage Loans and the Trust Subordinate Companion Loans due after the Cut-off Date (or with respect to a Qualified Substitute Mortgage Loan, the Due Date in the month of substitution); (iii) any REO Property (to the extent of the Trust’s interest therein) or

A-22-5 

the Trust’s beneficial interest in the Mortgaged Property securing a Non Serviced Whole Loan acquired under the related Non-Serviced PSA; (iv) all revenues received in respect of any REO Property (to the extent of the Trust’s interest therein); (v) the Master Servicer’s, the Special Servicer’s, the Certificate Administrator’s and the Trustee’s rights under the insurance policies with respect to the Mortgage Loans and the Trust Subordinate Companion Loans required to be maintained pursuant to the Pooling and Servicing Agreement and any proceeds thereof (to the extent of the Trust’s interest therein); (vi) any Assignment of Leases and any security agreements (to the extent of the Trust’s interest therein); (vii) any letters of credit, indemnities, guaranties or lease enhancement policies given as additional security for any related Mortgage Loans or Trust Subordinate Companion Loans (to the extent of the Trust’s interest therein); (viii) all assets deposited in the Loss of Value Reserve Fund and the Servicing Accounts (to the extent of the Trust’s interest therein), amounts on deposit in the Collection Account (to the extent of the Trust’s interest therein), the Lower-Tier REMIC Distribution Account, the Upper-Tier REMIC Distribution Account, the Trust Subordinate Companion Loan REMIC Distribution Accounts, the Regular Interest Distribution Account, the Excess Interest Distribution Account, the Interest Reserve Account, the Gain-on-Sale Reserve Account (to the extent of the Trust’s interest therein) and any REO Account (to the extent of the Trust’s interest therein), including any reinvestment income, as applicable; (ix) any Environmental Indemnity Agreements (to the extent of the Trust’s interest therein); (x) the rights and remedies of the Depositor under each Mortgage Loan Purchase Agreement (to the extent transferred to the Trustee); (xi) the Lower-Tier Regular Interests; (xii) the Trust Subordinate Companion Loan REMIC Regular Interests; and (xiii) the proceeds of the foregoing (other than any interest earned on deposits in the lock-box accounts, cash collateral accounts, escrow accounts and any reserve accounts, to the extent such interest belongs to the related Mortgagor).

This Certificate does not purport to summarize the Pooling and Servicing Agreement, and reference is made to the Pooling and Servicing Agreement for the interests, rights, benefits, obligations and duties evidenced hereby, and the limitations thereon, and the rights, duties and immunities of the Certificate Administrator and Trustee.

As provided in the Pooling and Servicing Agreement, subject to certain restrictions on transfer set forth therein, upon surrender for registration of transfer of any Certificate, the Certificate Administrator shall execute, authenticate and deliver, in the name of the designated transferee or transferees, one or more new Certificates in authorized denominations, in like aggregate interest and of the same Class.

Prior to due presentation of this Certificate for registration of transfer, the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Certificate Registrar, and any agent of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate Registrar may treat the Person in whose name any Certificate is registered as the owner of such Certificate for the purpose of receiving distributions as provided in the Pooling and Servicing Agreement and for all other purposes whatsoever, and none of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Certificate Registrar, or any agent of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset

(vi) to revise or add any other provisions with respect to matters or questions arising under the Pooling and Servicing Agreement or any other change; provided that the required action shall not adversely affect in any material respect the interests of any Certificateholder (including, for the avoidance of doubt, any Holder of a VRR Interest, a Y&L Towers VRR Interest or a Standard Highline VRR Interest) or any holder of a Serviced Pari Passu Companion Loan not consenting to such revision or addition, as evidenced in writing by an Opinion of Counsel, at the expense of the party requesting such amendment or as evidenced by a Rating Agency Confirmation from each of the Rating Agencies with respect to such amendment or supplement and confirmation of the applicable rating agencies that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings of any class of Serviced Companion Loan Securities, if any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement);

(viii) to modify the provisions of Sections 3.05 and 3.17 of the Pooling and Servicing Agreement (with respect to reimbursement of Nonrecoverable Advances and Workout-Delayed Reimbursement Amounts) if (a) the Depositor, the Master Servicer, the Trustee and, for so long as a Control Termination Event has not occurred and is not continuing and, with

A-22-8 

respect to any Mortgage Loans other than any Excluded Loan, as to the Directing Holder or, in the case of the Directing Certificateholder, the Holder of a majority of the Controlling Class, the Directing Holder, determine that the commercial mortgage backed securities industry standard for such provisions has changed, in order to conform to such industry standard, (b) such modification does not adversely affect the status of any Trust REMIC as a REMIC or the status of the Grantor Trust as a grantor trust under the relevant provisions of the Code, as evidenced by an Opinion of Counsel and (c) each Rating Agency has delivered a Rating Agency Confirmation and, with regard to any class of Serviced Companion Loan Securities, the applicable rating agencies have delivered a confirmation that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement);

(ix) to modify the procedures of the Pooling and Servicing Agreement relating to compliance with Rule 17g-5 of the Exchange Act; provided that such amendment shall not adversely affect in any material respects the interests of any Certificateholders (including, for the avoidance of doubt, any Holders of a VRR Interest, a Y&L Towers VRR Interest or a Standard Highline VRR Interest), as evidenced by (x) an Opinion of Counsel or (y) if any Certificate is then rated, receipt of Rating Agency Confirmation from each Rating Agency rating such Certificates; and provided, further, that the Certificate Administrator shall give notice of any such amendment to the 17g-5 Information Provider for posting to the 17g-5 Information Provider’s Website pursuant to Section 3.13(c) of the Pooling and Servicing Agreement and the Certificate Administrator shall post such notice to the Certificate Administrator’s Website;

Notwithstanding the foregoing, no such amendment (A) may change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations of any Mortgage Loan Seller under any Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan Seller as a third party beneficiary under the Pooling and

A-22-9 

Servicing Agreement, without the consent of such Mortgage Loan Seller or (B) may materially and adversely affect the holders of a Companion Loan without such Companion Holder’s consent.

The Pooling and Servicing Agreement may also be amended from time to time by the parties thereto with the consent of the Holders of Certificates of each Class affected by such amendment (including, for the avoidance of doubt, any Holders of the VRR Interest, the Y&L Towers VRR Interest or the Standard Highline VRR Interest to the extent any such amendment would adversely affect the rights of such Certificateholders) evidencing in the aggregate not less than a majority of the aggregate Percentage Interests constituting the Class for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of the Pooling and Servicing Agreement or of modifying in any manner the rights of the Holders of Certificates of such Class; provided, however, that no such amendment shall:

(i) reduce in any manner the amount of, or delay the timing of, payments received on the Mortgage Loans or the Trust Subordinate Companion Loans that are required to be distributed on a Certificate of any class without the consent of the Holder of the Certificate or which are required to be distributed to a Companion Holder without the consent of such Companion Holder; or

(ii) reduce the aforesaid percentage of Certificates of any Class the Holders of which are required to consent to any such amendment or remove the requirement to obtain consent of any Companion Holder or Holder of Loan-Specific Certificates, in any such case, without the consent of the Holders of all Certificates of such Class then-outstanding or such Companion Holders, as applicable; or

(iii) adversely affect the Voting Rights of any Class of Certificates without the consent of the Holders of all Certificates of such Class then outstanding; or

(iv) change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations of any Mortgage Loan Seller under such Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller; or

(v) amend the Servicing Standard without the consent of 100% of the Certificateholders or receipt of Rating Agency Confirmation from each Rating Agency and confirmation of the applicable rating agencies that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings of any Serviced Companion Loan Securities, if any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement) and, if required under the

A-22-10 

related Intercreditor Agreement, the consent of the holder of any AB Subordinate Companion Loan for each Serviced AB Whole Loan.

Notwithstanding the foregoing, none of the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Depositor, the Master Servicer nor the Special Servicer will be required to consent to any amendment to the Pooling and Servicing Agreement without having first received an Opinion of Counsel (at the Trust’s expense) to the effect that such amendment is permitted under the Pooling and Servicing Agreement, that all conditions precedent have been satisfied and that such amendment or the exercise of any power granted to the Master Servicer, the Special Servicer, the Depositor, the Trustee, the Certificate Administrator, the Operating Advisor, the Asset Representations Reviewer or any other specified person in accordance with such amendment will not result in the imposition of a tax on any portion of the Trust Fund or any Trust REMIC, or cause any Trust REMIC to fail to qualify as a REMIC or cause the Grantor Trust to fail to qualify as a grantor trust under the relevant provisions of the Code.

The Holders of the majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates may, in that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the Certificate Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage Loans (and all property acquired through exercise of remedies in respect of any related Mortgage Loan), the Trust Subordinate Companion Loans and the Trust’s portion of each REO Property remaining in the Trust Fund, and thereby effect termination of the Trust and early retirement of the then-outstanding Certificates, only on or after the first Distribution Date on which the aggregate Stated Principal Balances of the Mortgage Loans, the Trust Subordinate Companion Loans and the portion of any REO Loans held by the Trust is less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage Loans (solely for the purposes of this calculation, if such right is being exercised after December 2027 and the 237 East Fordham Road Mortgage Loan is still an asset of the Trust, then such Mortgage Loan will be excluded from the then-aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate Companion Loans and from the aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate Companion Loans as of the Cut-off Date) as set forth in the Pooling and Servicing Agreement.

Following the date on which the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class A-S, Class X-A, Class X-B, Class X-E, Class B and Class C Regular Interests have been reduced to zero (and provided that there is only one Holder (or multiple Holders acting in unanimity) of the then-outstanding Certificates (other than the Class Z and Class R Certificates)), the Sole Certificateholder shall have the right, with the consent of the Master Servicer, to exchange all of its Certificates (other than the Class Z and Class R Certificates) together with the payment or deemed payment of the Termination Purchase Amount for all of the Mortgage Loans, the Trust Subordinate Companion Loans and each REO Property remaining in the Trust Fund pursuant to the terms of the Pooling and Servicing Agreement.

The obligations created by the Pooling and Servicing Agreement and the Trust created thereby (other than the obligation of the Certificate Administrator to make payments to Certificateholders as provided for in the Pooling and Servicing Agreement), shall terminate upon reduction of the Certificate Balances of all the Certificates to zero (including, without limitation,

A-22-11 

any such final payment resulting from a termination of the Trust due to a sale of its property) pursuant to the terms of the Pooling and Servicing Agreement. In no event, however, will the Trust created by the Pooling and Servicing Agreement continue beyond the expiration of 21 years from the death of the last survivor of the descendants of Joseph P. Kennedy, the late Ambassador of the United States to the Court of St. James, living on the date hereof.

Unless the certificate of authentication hereon has been executed by the Authenticating Agent, by manual signature, this Certificate shall not be entitled to any benefit under the Pooling and Servicing Agreement or be valid for any purpose. The Certificate Registrar has executed this Certificate on behalf of the Trust as Certificate Registrar under the Pooling and Servicing Agreement and makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates, the Mortgage Loans or the Trust Subordinate Companion Loans.

This Certificate is issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of November 1, 2017 (the “Pooling and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities Corp., as Depositor, Wells Fargo Bank, National Association, as Certificate Administrator and as Trustee, Park Bridge Lender Services LLC, as Operating Advisor and as Asset Representations Reviewer, KeyBank National Association, as Master Servicer, and CWCapital Asset Management LLC, as Special Servicer. To the extent not defined herein, capitalized terms used herein shall have the meanings assigned thereto in the Pooling and Servicing Agreement.

This Certificate represents beneficial ownership of a “regular interest” in a “real estate mortgage investment conduit,” as those terms are defined, respectively, in Sections 860G(a)(1) and 860D of the Internal Revenue Code of 1986, as amended.

The Certificate Administrator makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates, the Mortgage Loans or the Trust Subordinate Companion Loans and has executed this Certificate in its limited capacity as Certificate Administrator under the Pooling and Servicing Agreement.

Pursuant to the terms of the Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution on any Certificate), on the 4th Business Day following the determination date of each month, commencing in December 2017 (each such date, a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related Record Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this Certificate) of that portion of the aggregate amount of principal and interest then distributable, if any, allocable to the Class UES-A Certificates for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement.

Interest accrued on this Certificate during an Interest Accrual Period, plus the aggregate unpaid Interest Shortfall with respect to this Certificate, if any, will be payable on the related Distribution Date to the extent provided in the Pooling and Servicing Agreement. The “Interest Accrual Period” with respect to any Distribution Date and with respect to the Class UES-A Certificates is the calendar month immediately preceding the month in which such Distribution Date occurs and is assumed to consist of 30 days.

All distributions (other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons in whose names the Certificates are registered at the close of business on each Record Date, which will be the close of business on the last Business Day of the month immediately preceding the month in which such Distribution Date occurs. Distributions are required to be made (a) by wire transfer of immediately available funds to the account of such Certificateholder at a bank or other entity having appropriate facilities

 A-22-4

therefor, if such Certificateholder provided the Certificate Administrator with written wiring instructions no less than five Business Days prior to the related Record Date (which wiring instructions may be in the form of a standing order applicable to all subsequent Distribution Dates), or otherwise (b) by check mailed to such Certificateholder at its address in the Certificate Register. The final distribution on each Certificate will be made in like manner, but only upon presentment and surrender of such Certificate at the offices of the Certificate Registrar or such other location specified in the notice to Certificateholders of such final distribution.

Any funds not distributed to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure of such Certificateholders to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited to the account or accounts of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been given pursuant to Section 4.01(l) of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within six months after the time specified in such notice, the Certificate Administrator shall mail a second notice to the remaining non tendering Certificateholders to surrender their Certificates for cancellation in order to receive the final distribution with respect thereto. If within one year after the second notice all such Certificates shall not have been surrendered for cancellation, the Certificate Administrator, directly or through an agent, shall take such steps to contact the remaining non tendering Certificateholders concerning the surrender of their Certificates as it shall deem appropriate and subject to escheatment and other applicable laws. The costs and expenses of holding such funds in trust and of contacting such Certificateholders following the first anniversary of the delivery of such second notice to the non-tendering Certificateholders shall be paid out of such funds. No interest shall accrue or be payable to any Certificateholder on any amount held in trust under the Pooling and Servicing Agreement by the Certificate Administrator as a result of such Certificateholder’s failure to surrender its Certificate(s) for final payment thereof in accordance with Section 4.01(l) of the Pooling and Servicing Agreement.

This Certificate is limited in right of payment to, among other things, certain collections and recoveries in respect of the Y&L Towers Trust Subordinate Companion Loan, as more specifically set forth herein and in the Pooling and Servicing Agreement.

As provided in the Pooling and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject to the Pooling and Servicing Agreement (including any Qualified Substitute Mortgage Loan replacing a removed Mortgage Loan) and the Trust Subordinate Companion Loans, together with the Mortgage Files relating thereto (subject to, in the case of a Serviced Whole Loan, the interests of the related Serviced Companion Noteholder in the related Mortgage File); (ii) all scheduled or unscheduled payments on or collections in respect of the Mortgage Loans and the Trust Subordinate Companion Loans due after the Cut-off Date (or with respect to a Qualified Substitute Mortgage Loan, the Due Date in the month of substitution); (iii) any REO Property (to the extent of the Trust’s interest therein) or the Trust’s beneficial interest in the Mortgaged Property securing a Non Serviced Whole Loan acquired under the related Non-Serviced PSA; (iv) all revenues received in respect of any REO Property (to the extent of the Trust’s interest therein); (v) the Master Servicer’s, the Special Servicer’s, the Certificate Administrator’s and the Trustee’s rights under the insurance policies with respect to the Mortgage Loans and the Trust Subordinate Companion Loans required to be maintained pursuant to the Pooling and Servicing Agreement and any proceeds thereof (to the

 A-22-5

extent of the Trust’s interest therein); (vi) any Assignment of Leases and any security agreements (to the extent of the Trust’s interest therein); (vii) any letters of credit, indemnities, guaranties or lease enhancement policies given as additional security for any related Mortgage Loans or Trust Subordinate Companion Loans (to the extent of the Trust’s interest therein); (viii) all assets deposited in the Loss of Value Reserve Fund and the Servicing Accounts (to the extent of the Trust’s interest therein), amounts on deposit in the Collection Account (to the extent of the Trust’s interest therein), the Lower-Tier REMIC Distribution Account, the Upper-Tier REMIC Distribution Account, the Trust Subordinate Companion Loan REMIC Distribution Accounts, the Regular Interest Distribution Account, the Excess Interest Distribution Account, the Interest Reserve Account, the Gain-on-Sale Reserve Account (to the extent of the Trust’s interest therein) and any REO Account (to the extent of the Trust’s interest therein), including any reinvestment income, as applicable; (ix) any Environmental Indemnity Agreements (to the extent of the Trust’s interest therein); (x) the rights and remedies of the Depositor under each Mortgage Loan Purchase Agreement (to the extent transferred to the Trustee); (xi) the Lower-Tier Regular Interests; (xii) the Trust Subordinate Companion Loan REMIC Regular Interests; and (xiii) the proceeds of the foregoing (other than any interest earned on deposits in the lock-box accounts, cash collateral accounts, escrow accounts and any reserve accounts, to the extent such interest belongs to the related Mortgagor).

This Certificate does not purport to summarize the Pooling and Servicing Agreement, and reference is made to the Pooling and Servicing Agreement for the interests, rights, benefits, obligations and duties evidenced hereby, and the limitations thereon, and the rights, duties and immunities of the Certificate Administrator and Trustee.

As provided in the Pooling and Servicing Agreement, subject to certain restrictions on transfer set forth therein, upon surrender for registration of transfer of any Certificate, the Certificate Administrator shall execute, authenticate and deliver, in the name of the designated transferee or transferees, one or more new Certificates in authorized denominations, in like aggregate interest and of the same Class.

Prior to due presentation of this Certificate for registration of transfer, the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Certificate Registrar, and any agent of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate Registrar may treat the Person in whose name any Certificate is registered as the owner of such Certificate for the purpose of receiving distributions as provided in the Pooling and Servicing Agreement and for all other purposes whatsoever, and none of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Certificate Registrar, or any agent of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate Registrar shall be affected by any notice to the contrary.

 A-22-7

(v) to modify, eliminate or add to the provisions of Section 5.03(o) of the Pooling and Servicing Agreement or any other provision of the Pooling and Servicing Agreement restricting transfer of the Class R Certificates; provided the Depositor has determined that such change shall not, as evidenced by an Opinion of Counsel, cause the Trust, any Trust REMIC or any of the Certificateholders (other than the Transferor) to be subject to a federal tax caused by a Transfer to a Person that is a Disqualified Organization or a Non-U.S. Tax Person;

(vi) to revise or add any other provisions with respect to matters or questions arising under the Pooling and Servicing Agreement or any other change; provided that the required action shall not adversely affect in any material respect the interests of any Certificateholder (including, for the avoidance of doubt, any Holder of a VRR Interest, a Y&L Towers VRR Interest or a Standard Highline VRR Interest) or any holder of a Serviced Pari Passu Companion Loan not consenting to such revision or addition, as evidenced in writing by an Opinion of Counsel, at the expense of the party requesting such amendment or as evidenced by a Rating Agency Confirmation from each of the Rating Agencies with respect to such amendment or supplement and confirmation of the applicable rating agencies that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings of any class of Serviced Companion Loan Securities, if any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement);

(vii) to amend or supplement any provision of the Pooling and Servicing Agreement to the extent necessary to maintain the then-current ratings assigned to each Class of Certificates by each Rating Agency, as evidenced by a Rating Agency Confirmation from each of the Rating Agencies and confirmation of the applicable rating agencies that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings of any class of Serviced Companion Loan Securities, if any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement); provided that such amendment or supplement shall not adversely affect in any material respect the interests of any Certificateholder (including, for the avoidance of doubt, any Holder of a VRR Interest, a Y&L Towers VRR Interest or a Standard Highline VRR Interest) not consenting to such amendment or supplement, as evidenced by an Opinion of Counsel;

(viii) to modify the provisions of Sections 3.05 and 3.17 of the Pooling and Servicing Agreement (with respect to reimbursement of Nonrecoverable Advances and Workout-Delayed Reimbursement Amounts) if (a) the

 A-22-8

Depositor, the Master Servicer, the Trustee and, for so long as a Control Termination Event has not occurred and is not continuing and, with respect to any Mortgage Loans other than any Excluded Loan, as to the Directing Holder or, in the case of the Directing Certificateholder, the Holder of a majority of the Controlling Class, the Directing Holder, determine that the commercial mortgage backed securities industry standard for such provisions has changed, in order to conform to such industry standard, (b) such modification does not adversely affect the status of any Trust REMIC as a REMIC or the status of the Grantor Trust as a grantor trust under the relevant provisions of the Code, as evidenced by an Opinion of Counsel and (c) each Rating Agency has delivered a Rating Agency Confirmation and, with regard to any class of Serviced Companion Loan Securities, the applicable rating agencies have delivered a confirmation that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement);

(ix) to modify the procedures of the Pooling and Servicing Agreement relating to compliance with Rule 17g-5 of the Exchange Act; provided that such amendment shall not adversely affect in any material respects the interests of any Certificateholders (including, for the avoidance of doubt, any Holders of a VRR Interest, a Y&L Towers VRR Interest or a Standard Highline VRR Interest), as evidenced by (x) an Opinion of Counsel or (y) if any Certificate is then rated, receipt of Rating Agency Confirmation from each Rating Agency rating such Certificates; and provided, further, that the Certificate Administrator shall give notice of any such amendment to the 17g-5 Information Provider for posting to the 17g-5 Information Provider’s Website pursuant to Section 3.13(c) of the Pooling and Servicing Agreement and the Certificate Administrator shall post such notice to the Certificate Administrator’s Website;

(x) to modify, eliminate or add to any provisions of the Pooling and Servicing Agreement to such extent as shall be necessary to comply with the requirements for use of Form SF-3 in registered offerings to the extent provided in CFR 239.45(b)(1)(ii), (iii) or (iv); or

(xi) to modify, eliminate or add to any of its provisions in the event the Credit Risk Retention Rules or any other regulations applicable to the risk retention requirements for this securitization transaction are amended or repealed, to the extent required to comply with any such amendment or to modify or eliminate the provision related to the risk retention requirements in the event of such repeal.

Notwithstanding the foregoing, no such amendment (A) may change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations of any

 A-22-9

Mortgage Loan Seller under any Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller or (B) may materially and adversely affect the holders of a Companion Loan without such Companion Holder’s consent.

The Pooling and Servicing Agreement may also be amended from time to time by the parties thereto with the consent of the Holders of Certificates of each Class affected by such amendment (including, for the avoidance of doubt, any Holders of the VRR Interest, the Y&L Towers VRR Interest or the Standard Highline VRR Interest to the extent any such amendment would adversely affect the rights of such Certificateholders) evidencing in the aggregate not less than a majority of the aggregate Percentage Interests constituting the Class for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of the Pooling and Servicing Agreement or of modifying in any manner the rights of the Holders of Certificates of such Class; provided, however, that no such amendment shall:

(i) reduce in any manner the amount of, or delay the timing of, payments received on the Mortgage Loans or the Trust Subordinate Companion Loans that are required to be distributed on a Certificate of any class without the consent of the Holder of the Certificate or which are required to be distributed to a Companion Holder without the consent of such Companion Holder; or

(ii) reduce the aforesaid percentage of Certificates of any Class the Holders of which are required to consent to any such amendment or remove the requirement to obtain consent of any Companion Holder or Holder of Loan-Specific Certificates, in any such case, without the consent of the Holders of all Certificates of such Class then-outstanding or such Companion Holders, as applicable; or

(iii) adversely affect the Voting Rights of any Class of Certificates without the consent of the Holders of all Certificates of such Class then outstanding; or

(iv) change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations of any Mortgage Loan Seller under such Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller; or

(v) amend the Servicing Standard without the consent of 100% of the Certificateholders or receipt of Rating Agency Confirmation from each Rating Agency and confirmation of the applicable rating agencies that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings of any Serviced Companion Loan Securities, if any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be

 A-22-10

considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement) and, if required under the related Intercreditor Agreement, the consent of the holder of any AB Subordinate Companion Loan for each Serviced AB Whole Loan.

Notwithstanding the foregoing, none of the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Depositor, the Master Servicer nor the Special Servicer will be required to consent to any amendment to the Pooling and Servicing Agreement without having first received an Opinion of Counsel (at the Trust’s expense) to the effect that such amendment is permitted under the Pooling and Servicing Agreement, that all conditions precedent have been satisfied and that such amendment or the exercise of any power granted to the Master Servicer, the Special Servicer, the Depositor, the Trustee, the Certificate Administrator, the Operating Advisor, the Asset Representations Reviewer or any other specified person in accordance with such amendment will not result in the imposition of a tax on any portion of the Trust Fund or any Trust REMIC, or cause any Trust REMIC to fail to qualify as a REMIC or cause the Grantor Trust to fail to qualify as a grantor trust under the relevant provisions of the Code.

The Holders of the majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates may, in that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the Certificate Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage Loans (and all property acquired through exercise of remedies in respect of any related Mortgage Loan), the Trust Subordinate Companion Loans and the Trust’s portion of each REO Property remaining in the Trust Fund, and thereby effect termination of the Trust and early retirement of the then-outstanding Certificates, only on or after the first Distribution Date on which the aggregate Stated Principal Balances of the Mortgage Loans, the Trust Subordinate Companion Loans and the portion of any REO Loans held by the Trust is less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage Loans (solely for the purposes of this calculation, if such right is being exercised after December 2027 and the 237 East Fordham Road Mortgage Loan is still an asset of the Trust, then such Mortgage Loan will be excluded from the then-aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate Companion Loans and from the aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate Companion Loans as of the Cut-off Date) as set forth in the Pooling and Servicing Agreement.

Following the date on which the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class A-S, Class X-A, Class X-B, Class X-E, Class B and Class C Regular Interests have been reduced to zero (and provided that there is only one Holder (or multiple Holders acting in unanimity) of the then-outstanding Certificates (other than the Class Z and Class R Certificates)), the Sole Certificateholder shall have the right, with the consent of the Master Servicer, to exchange all of its Certificates (other than the Class Z and Class R Certificates) together with the payment or deemed payment of the Termination Purchase Amount for all of the Mortgage Loans, the Trust Subordinate Companion Loans and each REO Property remaining in the Trust Fund pursuant to the terms of the Pooling and Servicing Agreement.

This Certificate is issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of November 1, 2017 (the “Pooling and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities Corp., as Depositor, Wells Fargo Bank, National Association, as Certificate Administrator and as Trustee, Park Bridge Lender Services LLC, as Operating Advisor and as Asset Representations Reviewer, KeyBank National Association, as Master Servicer, and CWCapital Asset Management LLC, as Special Servicer. To the extent not defined herein, capitalized terms used herein shall have the meanings assigned thereto in the Pooling and Servicing Agreement.

This Certificate represents beneficial ownership of a “regular interest” in a “real estate mortgage investment conduit,” as those terms are defined, respectively, in Sections 860G(a)(1) and 860D of the Internal Revenue Code of 1986, as amended.

The Certificate Administrator makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates, the Mortgage Loans or the Trust Subordinate Companion Loans and has executed this Certificate in its limited capacity as Certificate Administrator under the Pooling and Servicing Agreement.

Pursuant to the terms of the Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution on any Certificate), on the 4th Business Day following the determination date of each month, commencing in December 2017 (each such date, a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related Record Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this Certificate) of that portion of the aggregate amount of principal and interest then distributable, if any, allocable to the Class UES-B Certificates for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement.

Interest accrued on this Certificate during an Interest Accrual Period, plus the aggregate unpaid Interest Shortfall with respect to this Certificate, if any, will be payable on the related Distribution Date to the extent provided in the Pooling and Servicing Agreement. The “Interest Accrual Period” with respect to any Distribution Date and with respect to the Class UES-B Certificates is the calendar month immediately preceding the month in which such Distribution Date occurs and is assumed to consist of 30 days.

All distributions (other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons in whose names the Certificates are registered at the close of business on each Record Date, which will be the close of business on the last Business Day of the month immediately preceding the month in which such Distribution Date occurs. Distributions are required to be made (a) by wire transfer of immediately available funds

 A-26-4

to the account of such Certificateholder at a bank or other entity having appropriate facilities therefor, if such Certificateholder provided the Certificate Administrator with written wiring instructions no less than five Business Days prior to the related Record Date (which wiring instructions may be in the form of a standing order applicable to all subsequent Distribution Dates), or otherwise (b) by check mailed to such Certificateholder at its address in the Certificate Register. The final distribution on each Certificate will be made in like manner, but only upon presentment and surrender of such Certificate at the offices of the Certificate Registrar or such other location specified in the notice to Certificateholders of such final distribution.

Any funds not distributed to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure of such Certificateholders to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited to the account or accounts of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been given pursuant to Section 4.01(l) of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within six months after the time specified in such notice, the Certificate Administrator shall mail a second notice to the remaining non tendering Certificateholders to surrender their Certificates for cancellation in order to receive the final distribution with respect thereto. If within one year after the second notice all such Certificates shall not have been surrendered for cancellation, the Certificate Administrator, directly or through an agent, shall take such steps to contact the remaining non tendering Certificateholders concerning the surrender of their Certificates as it shall deem appropriate and subject to escheatment and other applicable laws. The costs and expenses of holding such funds in trust and of contacting such Certificateholders following the first anniversary of the delivery of such second notice to the non-tendering Certificateholders shall be paid out of such funds. No interest shall accrue or be payable to any Certificateholder on any amount held in trust under the Pooling and Servicing Agreement by the Certificate Administrator as a result of such Certificateholder’s failure to surrender its Certificate(s) for final payment thereof in accordance with Section 4.01(l) of the Pooling and Servicing Agreement.

This Certificate is limited in right of payment to, among other things, certain collections and recoveries in respect of the Y&L Towers Trust Subordinate Companion Loan, as more specifically set forth herein and in the Pooling and Servicing Agreement.

As provided in the Pooling and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject to the Pooling and Servicing Agreement (including any Qualified Substitute Mortgage Loan replacing a removed Mortgage Loan) and the Trust Subordinate Companion Loans, together with the Mortgage Files relating thereto (subject to, in the case of a Serviced Whole Loan, the interests of the related Serviced Companion Noteholder in the related Mortgage File); (ii) all scheduled or unscheduled payments on or collections in respect of the Mortgage Loans and the Trust Subordinate Companion Loans due after the Cut-off Date (or with respect to a Qualified Substitute Mortgage Loan, the Due Date in the month of substitution); (iii) any REO Property (to the extent of the Trust’s interest therein) or the Trust’s beneficial interest in the Mortgaged Property securing a Non Serviced Whole Loan acquired under the related Non-Serviced PSA; (iv) all revenues received in respect of any REO Property (to the extent of the Trust’s interest therein); (v) the Master Servicer’s, the Special Servicer’s, the Certificate Administrator’s and the Trustee’s rights under the insurance policies with respect to the Mortgage Loans and the Trust Subordinate Companion Loans required to be

 A-26-5

maintained pursuant to the Pooling and Servicing Agreement and any proceeds thereof (to the extent of the Trust’s interest therein); (vi) any Assignment of Leases and any security agreements (to the extent of the Trust’s interest therein); (vii) any letters of credit, indemnities, guaranties or lease enhancement policies given as additional security for any related Mortgage Loans or Trust Subordinate Companion Loans (to the extent of the Trust’s interest therein); (viii) all assets deposited in the Loss of Value Reserve Fund and the Servicing Accounts (to the extent of the Trust’s interest therein), amounts on deposit in the Collection Account (to the extent of the Trust’s interest therein), the Lower-Tier REMIC Distribution Account, the Upper-Tier REMIC Distribution Account, the Trust Subordinate Companion Loan REMIC Distribution Accounts, the Regular Interest Distribution Account, the Excess Interest Distribution Account, the Interest Reserve Account, the Gain-on-Sale Reserve Account (to the extent of the Trust’s interest therein) and any REO Account (to the extent of the Trust’s interest therein), including any reinvestment income, as applicable; (ix) any Environmental Indemnity Agreements (to the extent of the Trust’s interest therein); (x) the rights and remedies of the Depositor under each Mortgage Loan Purchase Agreement (to the extent transferred to the Trustee); (xi) the Lower-Tier Regular Interests; (xii) the Trust Subordinate Companion Loan REMIC Regular Interests; and (xiii) the proceeds of the foregoing (other than any interest earned on deposits in the lock-box accounts, cash collateral accounts, escrow accounts and any reserve accounts, to the extent such interest belongs to the related Mortgagor).

This Certificate does not purport to summarize the Pooling and Servicing Agreement, and reference is made to the Pooling and Servicing Agreement for the interests, rights, benefits, obligations and duties evidenced hereby, and the limitations thereon, and the rights, duties and immunities of the Certificate Administrator and Trustee.

As provided in the Pooling and Servicing Agreement, subject to certain restrictions on transfer set forth therein, upon surrender for registration of transfer of any Certificate, the Certificate Administrator shall execute, authenticate and deliver, in the name of the designated transferee or transferees, one or more new Certificates in authorized denominations, in like aggregate interest and of the same Class.

Prior to due presentation of this Certificate for registration of transfer, the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Certificate Registrar, and any agent of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate Registrar may treat the Person in whose name any Certificate is registered as the owner of such Certificate for the purpose of receiving distributions as provided in the Pooling and Servicing Agreement and for all other purposes whatsoever, and none of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Certificate Registrar, or any agent of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate Registrar shall be affected by any notice to the contrary.

The Pooling and Servicing Agreement may be amended from time to time by the Depositor, the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Certificate Administrator and the Trustee, without the consent of any of the Certificateholders or the Companion Holders:

(v) to modify, eliminate or add to the provisions of Section 5.03(o) of the Pooling and Servicing Agreement or any other provision of the Pooling and Servicing Agreement restricting transfer of the Class R Certificates; provided the Depositor has determined that such change shall not, as evidenced by an Opinion of Counsel, cause the Trust, any Trust REMIC or any of the Certificateholders (other than the Transferor) to be subject to a federal tax caused by a Transfer to a Person that is a Disqualified Organization or a Non-U.S. Tax Person;

(vi) to revise or add any other provisions with respect to matters or questions arising under the Pooling and Servicing Agreement or any other change; provided that the required action shall not adversely affect in any material respect the interests of any Certificateholder (including, for the avoidance of doubt, any Holder of a VRR Interest, a Y&L Towers VRR Interest or a Standard Highline VRR Interest) or any holder of a Serviced Pari Passu Companion Loan not consenting to such revision or addition, as evidenced in writing by an Opinion of Counsel, at the expense of the party requesting such amendment or as evidenced by a Rating Agency Confirmation from each of the Rating Agencies with respect to such amendment or supplement and confirmation of the applicable rating agencies that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings of any class of Serviced Companion Loan Securities, if any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement);

(vii) to amend or supplement any provision of the Pooling and Servicing Agreement to the extent necessary to maintain the then-current ratings assigned to each Class of Certificates by each Rating Agency, as evidenced by a Rating Agency Confirmation from each of the Rating Agencies and confirmation of the applicable rating agencies that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings of any class of Serviced Companion Loan Securities, if any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement); provided that such amendment or supplement shall not adversely affect in any material respect the interests of any Certificateholder (including, for the avoidance of doubt, any Holder of a VRR Interest, a Y&L Towers VRR Interest or a Standard Highline VRR Interest) not consenting to such amendment or supplement, as evidenced by an Opinion of Counsel;

(viii) to modify the provisions of Sections 3.05 and 3.17 of the Pooling and Servicing Agreement (with respect to reimbursement of Nonrecoverable Advances and Workout-Delayed Reimbursement Amounts) if (a) the

 A-26-8

Depositor, the Master Servicer, the Trustee and, for so long as a Control Termination Event has not occurred and is not continuing and, with respect to any Mortgage Loans other than any Excluded Loan, as to the Directing Holder or, in the case of the Directing Certificateholder, the Holder of a majority of the Controlling Class, the Directing Holder, determine that the commercial mortgage backed securities industry standard for such provisions has changed, in order to conform to such industry standard, (b) such modification does not adversely affect the status of any Trust REMIC as a REMIC or the status of the Grantor Trust as a grantor trust under the relevant provisions of the Code, as evidenced by an Opinion of Counsel and (c) each Rating Agency has delivered a Rating Agency Confirmation and, with regard to any class of Serviced Companion Loan Securities, the applicable rating agencies have delivered a confirmation that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement);

(ix) to modify the procedures of the Pooling and Servicing Agreement relating to compliance with Rule 17g-5 of the Exchange Act; provided that such amendment shall not adversely affect in any material respects the interests of any Certificateholders (including, for the avoidance of doubt, any Holders of a VRR Interest, a Y&L Towers VRR Interest or a Standard Highline VRR Interest), as evidenced by (x) an Opinion of Counsel or (y) if any Certificate is then rated, receipt of Rating Agency Confirmation from each Rating Agency rating such Certificates; and provided, further, that the Certificate Administrator shall give notice of any such amendment to the 17g-5 Information Provider for posting to the 17g-5 Information Provider’s Website pursuant to Section 3.13(c) of the Pooling and Servicing Agreement and the Certificate Administrator shall post such notice to the Certificate Administrator’s Website;

(x) to modify, eliminate or add to any provisions of the Pooling and Servicing Agreement to such extent as shall be necessary to comply with the requirements for use of Form SF-3 in registered offerings to the extent provided in CFR 239.45(b)(1)(ii), (iii) or (iv); or

(xi) to modify, eliminate or add to any of its provisions in the event the Credit Risk Retention Rules or any other regulations applicable to the risk retention requirements for this securitization transaction are amended or repealed, to the extent required to comply with any such amendment or to modify or eliminate the provision related to the risk retention requirements in the event of such repeal.

Notwithstanding the foregoing, no such amendment (A) may change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations of any

 A-26-9

Mortgage Loan Seller under any Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller or (B) may materially and adversely affect the holders of a Companion Loan without such Companion Holder’s consent.

The Pooling and Servicing Agreement may also be amended from time to time by the parties thereto with the consent of the Holders of Certificates of each Class affected by such amendment (including, for the avoidance of doubt, any Holders of the VRR Interest, the Y&L Towers VRR Interest or the Standard Highline VRR Interest to the extent any such amendment would adversely affect the rights of such Certificateholders) evidencing in the aggregate not less than a majority of the aggregate Percentage Interests constituting the Class for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of the Pooling and Servicing Agreement or of modifying in any manner the rights of the Holders of Certificates of such Class; provided, however, that no such amendment shall:

(i) reduce in any manner the amount of, or delay the timing of, payments received on the Mortgage Loans or the Trust Subordinate Companion Loans that are required to be distributed on a Certificate of any class without the consent of the Holder of the Certificate or which are required to be distributed to a Companion Holder without the consent of such Companion Holder; or

(ii) reduce the aforesaid percentage of Certificates of any Class the Holders of which are required to consent to any such amendment or remove the requirement to obtain consent of any Companion Holder or Holder of Loan-Specific Certificates, in any such case, without the consent of the Holders of all Certificates of such Class then-outstanding or such Companion Holders, as applicable; or

(iii) adversely affect the Voting Rights of any Class of Certificates without the consent of the Holders of all Certificates of such Class then outstanding; or

(iv) change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations of any Mortgage Loan Seller under such Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller; or

(v) amend the Servicing Standard without the consent of 100% of the Certificateholders or receipt of Rating Agency Confirmation from each Rating Agency and confirmation of the applicable rating agencies that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings of any Serviced Companion Loan Securities, if any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be

 A-26-10

considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement) and, if required under the related Intercreditor Agreement, the consent of the holder of any AB Subordinate Companion Loan for each Serviced AB Whole Loan.

Notwithstanding the foregoing, none of the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Depositor, the Master Servicer nor the Special Servicer will be required to consent to any amendment to the Pooling and Servicing Agreement without having first received an Opinion of Counsel (at the Trust’s expense) to the effect that such amendment is permitted under the Pooling and Servicing Agreement, that all conditions precedent have been satisfied and that such amendment or the exercise of any power granted to the Master Servicer, the Special Servicer, the Depositor, the Trustee, the Certificate Administrator, the Operating Advisor, the Asset Representations Reviewer or any other specified person in accordance with such amendment will not result in the imposition of a tax on any portion of the Trust Fund or any Trust REMIC, or cause any Trust REMIC to fail to qualify as a REMIC or cause the Grantor Trust to fail to qualify as a grantor trust under the relevant provisions of the Code.

The Holders of the majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates may, in that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the Certificate Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage Loans (and all property acquired through exercise of remedies in respect of any related Mortgage Loan), the Trust Subordinate Companion Loans and the Trust’s portion of each REO Property remaining in the Trust Fund, and thereby effect termination of the Trust and early retirement of the then-outstanding Certificates, only on or after the first Distribution Date on which the aggregate Stated Principal Balances of the Mortgage Loans, the Trust Subordinate Companion Loans and the portion of any REO Loans held by the Trust is less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage Loans (solely for the purposes of this calculation, if such right is being exercised after December 2027 and the 237 East Fordham Road Mortgage Loan is still an asset of the Trust, then such Mortgage Loan will be excluded from the then-aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate Companion Loans and from the aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate Companion Loans as of the Cut-off Date) as set forth in the Pooling and Servicing Agreement.

Following the date on which the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class A-S, Class X-A, Class X-B, Class X-E, Class B and Class C Regular Interests have been reduced to zero (and provided that there is only one Holder (or multiple Holders acting in unanimity) of the then-outstanding Certificates (other than the Class Z and Class R Certificates)), the Sole Certificateholder shall have the right, with the consent of the Master Servicer, to exchange all of its Certificates (other than the Class Z and Class R Certificates) together with the payment or deemed payment of the Termination Purchase Amount for all of the Mortgage Loans, the Trust Subordinate Companion Loans and each REO Property remaining in the Trust Fund pursuant to the terms of the Pooling and Servicing Agreement.

The obligations created by the Pooling and Servicing Agreement and the Trust created thereby (other than the obligation of the Certificate Administrator to make payments to

 A-26-11

Certificateholders as provided for in the Pooling and Servicing Agreement), shall terminate upon reduction of the Certificate Balances of all the Certificates to zero (including, without limitation, any such final payment resulting from a termination of the Trust due to a sale of its property) pursuant to the terms of the Pooling and Servicing Agreement. In no event, however, will the Trust created by the Pooling and Servicing Agreement continue beyond the expiration of 21 years from the death of the last survivor of the descendants of Joseph P. Kennedy, the late Ambassador of the United States to the Court of St. James, living on the date hereof.

Unless the certificate of authentication hereon has been executed by the Authenticating Agent, by manual signature, this Certificate shall not be entitled to any benefit under the Pooling and Servicing Agreement or be valid for any purpose. The Certificate Registrar has executed this Certificate on behalf of the Trust as Certificate Registrar under the Pooling and Servicing Agreement and makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates, the Mortgage Loans or the Trust Subordinate Companion Loans.

This Certificate is issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of November 1, 2017 (the “Pooling and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities Corp., as Depositor, Wells Fargo Bank, National Association, as Certificate Administrator and as Trustee, Park Bridge Lender Services LLC, as Operating Advisor and as Asset Representations Reviewer, KeyBank National Association, as Master Servicer, and CWCapital Asset Management LLC, as Special Servicer. To the extent not defined herein, capitalized terms used herein shall have the meanings assigned thereto in the Pooling and Servicing Agreement.

This Certificate represents beneficial ownership of a “regular interest” in a “real estate mortgage investment conduit,” as those terms are defined, respectively, in Sections 860G(a)(1) and 860D of the Internal Revenue Code of 1986, as amended.

The Certificate Administrator makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates, the Mortgage Loans or the Trust Subordinate Companion Loans and has executed this Certificate in its limited capacity as Certificate Administrator under the Pooling and Servicing Agreement.

Pursuant to the terms of the Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution on any Certificate), on the 4th Business Day following the determination date of each month, commencing in December 2017 (each such date, a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related Record Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this Certificate) of that portion of the aggregate amount of principal and interest then distributable, if any, allocable to the Class UES-C Certificates for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement.

Interest accrued on this Certificate during an Interest Accrual Period, plus the aggregate unpaid Interest Shortfall with respect to this Certificate, if any, will be payable on the related Distribution Date to the extent provided in the Pooling and Servicing Agreement. The “Interest Accrual Period” with respect to any Distribution Date and with respect to the Class UES-C Certificates is the calendar month immediately preceding the month in which such Distribution Date occurs and is assumed to consist of 30 days.

All distributions (other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons in whose names the Certificates are registered at the close of business on each Record Date, which will be the close of business on the last Business Day of the month immediately preceding the month in which such Distribution Date occurs. Distributions are required to be made (a) by wire transfer of immediately available funds to the account of such Certificateholder at a bank or other entity having appropriate facilities

A-26-4 

therefor, if such Certificateholder provided the Certificate Administrator with written wiring instructions no less than five Business Days prior to the related Record Date (which wiring instructions may be in the form of a standing order applicable to all subsequent Distribution Dates), or otherwise (b) by check mailed to such Certificateholder at its address in the Certificate Register. The final distribution on each Certificate will be made in like manner, but only upon presentment and surrender of such Certificate at the offices of the Certificate Registrar or such other location specified in the notice to Certificateholders of such final distribution.

Any funds not distributed to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure of such Certificateholders to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited to the account or accounts of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been given pursuant to Section 4.01(l) of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within six months after the time specified in such notice, the Certificate Administrator shall mail a second notice to the remaining non tendering Certificateholders to surrender their Certificates for cancellation in order to receive the final distribution with respect thereto. If within one year after the second notice all such Certificates shall not have been surrendered for cancellation, the Certificate Administrator, directly or through an agent, shall take such steps to contact the remaining non tendering Certificateholders concerning the surrender of their Certificates as it shall deem appropriate and subject to escheatment and other applicable laws. The costs and expenses of holding such funds in trust and of contacting such Certificateholders following the first anniversary of the delivery of such second notice to the non-tendering Certificateholders shall be paid out of such funds. No interest shall accrue or be payable to any Certificateholder on any amount held in trust under the Pooling and Servicing Agreement by the Certificate Administrator as a result of such Certificateholder’s failure to surrender its Certificate(s) for final payment thereof in accordance with Section 4.01(l) of the Pooling and Servicing Agreement.

This Certificate is limited in right of payment to, among other things, certain collections and recoveries in respect of the Y&L Towers Trust Subordinate Companion Loan, as more specifically set forth herein and in the Pooling and Servicing Agreement.

As provided in the Pooling and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject to the Pooling and Servicing Agreement (including any Qualified Substitute Mortgage Loan replacing a removed Mortgage Loan) and the Trust Subordinate Companion Loans, together with the Mortgage Files relating thereto (subject to, in the case of a Serviced Whole Loan, the interests of the related Serviced Companion Noteholder in the related Mortgage File); (ii) all scheduled or unscheduled payments on or collections in respect of the Mortgage Loans and the Trust Subordinate Companion Loans due after the Cut-off Date (or with respect to a Qualified Substitute Mortgage Loan, the Due Date in the month of substitution); (iii) any REO Property (to the extent of the Trust’s interest therein) or the Trust’s beneficial interest in the Mortgaged Property securing a Non Serviced Whole Loan acquired under the related Non-Serviced PSA; (iv) all revenues received in respect of any REO Property (to the extent of the Trust’s interest therein); (v) the Master Servicer’s, the Special Servicer’s, the Certificate Administrator’s and the Trustee’s rights under the insurance policies with respect to the Mortgage Loans and the Trust Subordinate Companion Loans required to be maintained pursuant to the Pooling and Servicing Agreement and any proceeds thereof (to the

A-26-5 

extent of the Trust’s interest therein); (vi) any Assignment of Leases and any security agreements (to the extent of the Trust’s interest therein); (vii) any letters of credit, indemnities, guaranties or lease enhancement policies given as additional security for any related Mortgage Loans or Trust Subordinate Companion Loans (to the extent of the Trust’s interest therein); (viii) all assets deposited in the Loss of Value Reserve Fund and the Servicing Accounts (to the extent of the Trust’s interest therein), amounts on deposit in the Collection Account (to the extent of the Trust’s interest therein), the Lower-Tier REMIC Distribution Account, the Upper-Tier REMIC Distribution Account, the Trust Subordinate Companion Loan REMIC Distribution Accounts, the Regular Interest Distribution Account, the Excess Interest Distribution Account, the Interest Reserve Account, the Gain-on-Sale Reserve Account (to the extent of the Trust’s interest therein) and any REO Account (to the extent of the Trust’s interest therein), including any reinvestment income, as applicable; (ix) any Environmental Indemnity Agreements (to the extent of the Trust’s interest therein); (x) the rights and remedies of the Depositor under each Mortgage Loan Purchase Agreement (to the extent transferred to the Trustee); (xi) the Lower-Tier Regular Interests; (xii) the Trust Subordinate Companion Loan REMIC Regular Interests; and (xiii) the proceeds of the foregoing (other than any interest earned on deposits in the lock-box accounts, cash collateral accounts, escrow accounts and any reserve accounts, to the extent such interest belongs to the related Mortgagor).

This Certificate does not purport to summarize the Pooling and Servicing Agreement, and reference is made to the Pooling and Servicing Agreement for the interests, rights, benefits, obligations and duties evidenced hereby, and the limitations thereon, and the rights, duties and immunities of the Certificate Administrator and Trustee.

As provided in the Pooling and Servicing Agreement, subject to certain restrictions on transfer set forth therein, upon surrender for registration of transfer of any Certificate, the Certificate Administrator shall execute, authenticate and deliver, in the name of the designated transferee or transferees, one or more new Certificates in authorized denominations, in like aggregate interest and of the same Class.

Prior to due presentation of this Certificate for registration of transfer, the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Certificate Registrar, and any agent of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate Registrar may treat the Person in whose name any Certificate is registered as the owner of such Certificate for the purpose of receiving distributions as provided in the Pooling and Servicing Agreement and for all other purposes whatsoever, and none of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Certificate Registrar, or any agent of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate Registrar shall be affected by any notice to the contrary.

(vi) to revise or add any other provisions with respect to matters or questions arising under the Pooling and Servicing Agreement or any other change; provided that the required action shall not adversely affect in any material respect the interests of any Certificateholder (including, for the avoidance of doubt, any Holder of a VRR Interest, a Y&L Towers VRR Interest or a Standard Highline VRR Interest) or any holder of a Serviced Pari Passu Companion Loan not consenting to such revision or addition, as evidenced in writing by an Opinion of Counsel, at the expense of the party requesting such amendment or as evidenced by a Rating Agency Confirmation from each of the Rating Agencies with respect to such amendment or supplement and confirmation of the applicable rating agencies that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings of any class of Serviced Companion Loan Securities, if any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement);

(viii) to modify the provisions of Sections 3.05 and 3.17 of the Pooling and Servicing Agreement (with respect to reimbursement of Nonrecoverable Advances and Workout-Delayed Reimbursement Amounts) if (a) the

A-26-8 

Depositor, the Master Servicer, the Trustee and, for so long as a Control Termination Event has not occurred and is not continuing and, with respect to any Mortgage Loans other than any Excluded Loan, as to the Directing Holder or, in the case of the Directing Certificateholder, the Holder of a majority of the Controlling Class, the Directing Holder, determine that the commercial mortgage backed securities industry standard for such provisions has changed, in order to conform to such industry standard, (b) such modification does not adversely affect the status of any Trust REMIC as a REMIC or the status of the Grantor Trust as a grantor trust under the relevant provisions of the Code, as evidenced by an Opinion of Counsel and (c) each Rating Agency has delivered a Rating Agency Confirmation and, with regard to any class of Serviced Companion Loan Securities, the applicable rating agencies have delivered a confirmation that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement);

(ix) to modify the procedures of the Pooling and Servicing Agreement relating to compliance with Rule 17g-5 of the Exchange Act; provided that such amendment shall not adversely affect in any material respects the interests of any Certificateholders (including, for the avoidance of doubt, any Holders of a VRR Interest, a Y&L Towers VRR Interest or a Standard Highline VRR Interest), as evidenced by (x) an Opinion of Counsel or (y) if any Certificate is then rated, receipt of Rating Agency Confirmation from each Rating Agency rating such Certificates; and provided, further, that the Certificate Administrator shall give notice of any such amendment to the 17g-5 Information Provider for posting to the 17g-5 Information Provider’s Website pursuant to Section 3.13(c) of the Pooling and Servicing Agreement and the Certificate Administrator shall post such notice to the Certificate Administrator’s Website;

Notwithstanding the foregoing, no such amendment (A) may change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations of any

A-26-9 

Mortgage Loan Seller under any Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller or (B) may materially and adversely affect the holders of a Companion Loan without such Companion Holder’s consent.

The Pooling and Servicing Agreement may also be amended from time to time by the parties thereto with the consent of the Holders of Certificates of each Class affected by such amendment (including, for the avoidance of doubt, any Holders of the VRR Interest, the Y&L Towers VRR Interest or the Standard Highline VRR Interest to the extent any such amendment would adversely affect the rights of such Certificateholders) evidencing in the aggregate not less than a majority of the aggregate Percentage Interests constituting the Class for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of the Pooling and Servicing Agreement or of modifying in any manner the rights of the Holders of Certificates of such Class; provided, however, that no such amendment shall:

(i) reduce in any manner the amount of, or delay the timing of, payments received on the Mortgage Loans or the Trust Subordinate Companion Loans that are required to be distributed on a Certificate of any class without the consent of the Holder of the Certificate or which are required to be distributed to a Companion Holder without the consent of such Companion Holder; or

(ii) reduce the aforesaid percentage of Certificates of any Class the Holders of which are required to consent to any such amendment or remove the requirement to obtain consent of any Companion Holder or Holder of Loan-Specific Certificates, in any such case, without the consent of the Holders of all Certificates of such Class then-outstanding or such Companion Holders, as applicable; or

(iii) adversely affect the Voting Rights of any Class of Certificates without the consent of the Holders of all Certificates of such Class then outstanding; or

(iv) change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations of any Mortgage Loan Seller under such Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller; or

(v) amend the Servicing Standard without the consent of 100% of the Certificateholders or receipt of Rating Agency Confirmation from each Rating Agency and confirmation of the applicable rating agencies that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings of any Serviced Companion Loan Securities, if any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be

A-26-10 

considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement) and, if required under the related Intercreditor Agreement, the consent of the holder of any AB Subordinate Companion Loan for each Serviced AB Whole Loan.

Notwithstanding the foregoing, none of the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Depositor, the Master Servicer nor the Special Servicer will be required to consent to any amendment to the Pooling and Servicing Agreement without having first received an Opinion of Counsel (at the Trust’s expense) to the effect that such amendment is permitted under the Pooling and Servicing Agreement, that all conditions precedent have been satisfied and that such amendment or the exercise of any power granted to the Master Servicer, the Special Servicer, the Depositor, the Trustee, the Certificate Administrator, the Operating Advisor, the Asset Representations Reviewer or any other specified person in accordance with such amendment will not result in the imposition of a tax on any portion of the Trust Fund or any Trust REMIC, or cause any Trust REMIC to fail to qualify as a REMIC or cause the Grantor Trust to fail to qualify as a grantor trust under the relevant provisions of the Code.

The Holders of the majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates may, in that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the Certificate Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage Loans (and all property acquired through exercise of remedies in respect of any related Mortgage Loan), the Trust Subordinate Companion Loans and the Trust’s portion of each REO Property remaining in the Trust Fund, and thereby effect termination of the Trust and early retirement of the then-outstanding Certificates, only on or after the first Distribution Date on which the aggregate Stated Principal Balances of the Mortgage Loans, the Trust Subordinate Companion Loans and the portion of any REO Loans held by the Trust is less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage Loans (solely for the purposes of this calculation, if such right is being exercised after December 2027 and the 237 East Fordham Road Mortgage Loan is still an asset of the Trust, then such Mortgage Loan will be excluded from the then-aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate Companion Loans and from the aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate Companion Loans as of the Cut-off Date) as set forth in the Pooling and Servicing Agreement.

Following the date on which the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class A-S, Class X-A, Class X-B, Class X-E, Class B and Class C Regular Interests have been reduced to zero (and provided that there is only one Holder (or multiple Holders acting in unanimity) of the then-outstanding Certificates (other than the Class Z and Class R Certificates)), the Sole Certificateholder shall have the right, with the consent of the Master Servicer, to exchange all of its Certificates (other than the Class Z and Class R Certificates) together with the payment or deemed payment of the Termination Purchase Amount for all of the Mortgage Loans, the Trust Subordinate Companion Loans and each REO Property remaining in the Trust Fund pursuant to the terms of the Pooling and Servicing Agreement.

The obligations created by the Pooling and Servicing Agreement and the Trust created thereby (other than the obligation of the Certificate Administrator to make payments to

A-26-11 

Certificateholders as provided for in the Pooling and Servicing Agreement), shall terminate upon reduction of the Certificate Balances of all the Certificates to zero (including, without limitation, any such final payment resulting from a termination of the Trust due to a sale of its property) pursuant to the terms of the Pooling and Servicing Agreement. In no event, however, will the Trust created by the Pooling and Servicing Agreement continue beyond the expiration of 21 years from the death of the last survivor of the descendants of Joseph P. Kennedy, the late Ambassador of the United States to the Court of St. James, living on the date hereof.

Unless the certificate of authentication hereon has been executed by the Authenticating Agent, by manual signature, this Certificate shall not be entitled to any benefit under the Pooling and Servicing Agreement or be valid for any purpose. The Certificate Registrar has executed this Certificate on behalf of the Trust as Certificate Registrar under the Pooling and Servicing Agreement and makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates, the Mortgage Loans or the Trust Subordinate Companion Loans.

A-26-12 

IN WITNESS WHEREOF, the Certificate Administrator has caused this Class UES-C Certificate to be duly executed.

This Certificate is issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of November 1, 2017 (the “Pooling and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities Corp., as Depositor, Wells Fargo Bank, National Association, as Certificate Administrator and as Trustee, Park Bridge Lender Services LLC, as Operating Advisor and as Asset Representations Reviewer, KeyBank National Association, as Master Servicer, and CWCapital Asset Management LLC, as Special Servicer. To the extent not defined herein, capitalized terms used herein shall have the meanings assigned thereto in the Pooling and Servicing Agreement.

This Certificate represents beneficial ownership of a “regular interest” in a “real estate mortgage investment conduit,” as those terms are defined, respectively, in Sections 860G(a)(1) and 860D of the Internal Revenue Code of 1986, as amended.

The Certificate Administrator makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates, the Mortgage Loans or the Trust Subordinate Companion Loans and has executed this Certificate in its limited capacity as Certificate Administrator under the Pooling and Servicing Agreement.

Pursuant to the terms of the Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution on any Certificate), on the 4th Business Day following the determination date of each month, commencing in December 2017 (each such date, a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related Record Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this Certificate) of that portion of the aggregate amount of principal and interest then distributable, if any, allocable to the Class UES-D Certificates for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement.

Interest accrued on this Certificate during an Interest Accrual Period, plus the aggregate unpaid Interest Shortfall with respect to this Certificate, if any, will be payable on the related Distribution Date to the extent provided in the Pooling and Servicing Agreement. The “Interest Accrual Period” with respect to any Distribution Date and with respect to the Class UES-D Certificates is the calendar month immediately preceding the month in which such Distribution Date occurs and is assumed to consist of 30 days.

All distributions (other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons in whose names the Certificates are registered at the close of business on each Record Date, which will be the close of business on the last Business Day of the month immediately preceding the month in which such Distribution Date occurs. Distributions are required to be made (a) by wire transfer of immediately available funds to the account of such Certificateholder at a bank or other entity having appropriate facilities

A-26-5 

therefor, if such Certificateholder provided the Certificate Administrator with written wiring instructions no less than five Business Days prior to the related Record Date (which wiring instructions may be in the form of a standing order applicable to all subsequent Distribution Dates), or otherwise (b) by check mailed to such Certificateholder at its address in the Certificate Register. The final distribution on each Certificate will be made in like manner, but only upon presentment and surrender of such Certificate at the offices of the Certificate Registrar or such other location specified in the notice to Certificateholders of such final distribution.

Any funds not distributed to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure of such Certificateholders to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited to the account or accounts of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been given pursuant to Section 4.01(l) of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within six months after the time specified in such notice, the Certificate Administrator shall mail a second notice to the remaining non tendering Certificateholders to surrender their Certificates for cancellation in order to receive the final distribution with respect thereto. If within one year after the second notice all such Certificates shall not have been surrendered for cancellation, the Certificate Administrator, directly or through an agent, shall take such steps to contact the remaining non tendering Certificateholders concerning the surrender of their Certificates as it shall deem appropriate and subject to escheatment and other applicable laws. The costs and expenses of holding such funds in trust and of contacting such Certificateholders following the first anniversary of the delivery of such second notice to the non-tendering Certificateholders shall be paid out of such funds. No interest shall accrue or be payable to any Certificateholder on any amount held in trust under the Pooling and Servicing Agreement by the Certificate Administrator as a result of such Certificateholder’s failure to surrender its Certificate(s) for final payment thereof in accordance with Section 4.01(l) of the Pooling and Servicing Agreement.

This Certificate is limited in right of payment to, among other things, certain collections and recoveries in respect of the Y&L Towers Trust Subordinate Companion Loan, as more specifically set forth herein and in the Pooling and Servicing Agreement.

As provided in the Pooling and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject to the Pooling and Servicing Agreement (including any Qualified Substitute Mortgage Loan replacing a removed Mortgage Loan) and the Trust Subordinate Companion Loans, together with the Mortgage Files relating thereto (subject to, in the case of a Serviced Whole Loan, the interests of the related Serviced Companion Noteholder in the related Mortgage File); (ii) all scheduled or unscheduled payments on or collections in respect of the Mortgage Loans and the Trust Subordinate Companion Loans due after the Cut-off Date (or with respect to a Qualified Substitute Mortgage Loan, the Due Date in the month of substitution); (iii) any REO Property (to the extent of the Trust’s interest therein) or the Trust’s beneficial interest in the Mortgaged Property securing a Non Serviced Whole Loan acquired under the related Non-Serviced PSA; (iv) all revenues received in respect of any REO Property (to the extent of the Trust’s interest therein); (v) the Master Servicer’s, the Special Servicer’s, the Certificate Administrator’s and the Trustee’s rights under the insurance policies with respect to the Mortgage Loans and the Trust Subordinate Companion Loans required to be maintained pursuant to the Pooling and Servicing Agreement and any proceeds thereof (to the

A-26-6 

extent of the Trust’s interest therein); (vi) any Assignment of Leases and any security agreements (to the extent of the Trust’s interest therein); (vii) any letters of credit, indemnities, guaranties or lease enhancement policies given as additional security for any related Mortgage Loans or Trust Subordinate Companion Loans (to the extent of the Trust’s interest therein); (viii) all assets deposited in the Loss of Value Reserve Fund and the Servicing Accounts (to the extent of the Trust’s interest therein), amounts on deposit in the Collection Account (to the extent of the Trust’s interest therein), the Lower-Tier REMIC Distribution Account, the Upper-Tier REMIC Distribution Account, the Trust Subordinate Companion Loan REMIC Distribution Accounts, the Regular Interest Distribution Account, the Excess Interest Distribution Account, the Interest Reserve Account, the Gain-on-Sale Reserve Account (to the extent of the Trust’s interest therein) and any REO Account (to the extent of the Trust’s interest therein), including any reinvestment income, as applicable; (ix) any Environmental Indemnity Agreements (to the extent of the Trust’s interest therein); (x) the rights and remedies of the Depositor under each Mortgage Loan Purchase Agreement (to the extent transferred to the Trustee); (xi) the Lower-Tier Regular Interests; (xii) the Trust Subordinate Companion Loan REMIC Regular Interests; and (xiii) the proceeds of the foregoing (other than any interest earned on deposits in the lock-box accounts, cash collateral accounts, escrow accounts and any reserve accounts, to the extent such interest belongs to the related Mortgagor).

This Certificate does not purport to summarize the Pooling and Servicing Agreement, and reference is made to the Pooling and Servicing Agreement for the interests, rights, benefits, obligations and duties evidenced hereby, and the limitations thereon, and the rights, duties and immunities of the Certificate Administrator and Trustee.

As provided in the Pooling and Servicing Agreement, subject to certain restrictions on transfer set forth therein, upon surrender for registration of transfer of any Certificate, the Certificate Administrator shall execute, authenticate and deliver, in the name of the designated transferee or transferees, one or more new Certificates in authorized denominations, in like aggregate interest and of the same Class.

Prior to due presentation of this Certificate for registration of transfer, the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Certificate Registrar, and any agent of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate Registrar may treat the Person in whose name any Certificate is registered as the owner of such Certificate for the purpose of receiving distributions as provided in the Pooling and Servicing Agreement and for all other purposes whatsoever, and none of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Certificate Registrar, or any agent of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate Registrar shall be affected by any notice to the contrary.

Notwithstanding the foregoing, no such amendment (A) may change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations of any

A-26-10 

Mortgage Loan Seller under any Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller or (B) may materially and adversely affect the holders of a Companion Loan without such Companion Holder’s consent.

The Pooling and Servicing Agreement may also be amended from time to time by the parties thereto with the consent of the Holders of Certificates of each Class affected by such amendment (including, for the avoidance of doubt, any Holders of the VRR Interest, the Y&L Towers VRR Interest or the Standard Highline VRR Interest to the extent any such amendment would adversely affect the rights of such Certificateholders) evidencing in the aggregate not less than a majority of the aggregate Percentage Interests constituting the Class for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of the Pooling and Servicing Agreement or of modifying in any manner the rights of the Holders of Certificates of such Class; provided, however, that no such amendment shall:

(i) reduce in any manner the amount of, or delay the timing of, payments received on the Mortgage Loans or the Trust Subordinate Companion Loans that are required to be distributed on a Certificate of any class without the consent of the Holder of the Certificate or which are required to be distributed to a Companion Holder without the consent of such Companion Holder; or

(ii) reduce the aforesaid percentage of Certificates of any Class the Holders of which are required to consent to any such amendment or remove the requirement to obtain consent of any Companion Holder or Holder of Loan-Specific Certificates, in any such case, without the consent of the Holders of all Certificates of such Class then-outstanding or such Companion Holders, as applicable; or

(iii) adversely affect the Voting Rights of any Class of Certificates without the consent of the Holders of all Certificates of such Class then outstanding; or

(iv) change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations of any Mortgage Loan Seller under such Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller; or

(v) amend the Servicing Standard without the consent of 100% of the Certificateholders or receipt of Rating Agency Confirmation from each Rating Agency and confirmation of the applicable rating agencies that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings of any Serviced Companion Loan Securities, if any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be

A-26-11 

considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement) and, if required under the related Intercreditor Agreement, the consent of the holder of any AB Subordinate Companion Loan for each Serviced AB Whole Loan.

Notwithstanding the foregoing, none of the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Depositor, the Master Servicer nor the Special Servicer will be required to consent to any amendment to the Pooling and Servicing Agreement without having first received an Opinion of Counsel (at the Trust’s expense) to the effect that such amendment is permitted under the Pooling and Servicing Agreement, that all conditions precedent have been satisfied and that such amendment or the exercise of any power granted to the Master Servicer, the Special Servicer, the Depositor, the Trustee, the Certificate Administrator, the Operating Advisor, the Asset Representations Reviewer or any other specified person in accordance with such amendment will not result in the imposition of a tax on any portion of the Trust Fund or any Trust REMIC, or cause any Trust REMIC to fail to qualify as a REMIC or cause the Grantor Trust to fail to qualify as a grantor trust under the relevant provisions of the Code.

The Holders of the majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates may, in that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the Certificate Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage Loans (and all property acquired through exercise of remedies in respect of any related Mortgage Loan), the Trust Subordinate Companion Loans and the Trust’s portion of each REO Property remaining in the Trust Fund, and thereby effect termination of the Trust and early retirement of the then-outstanding Certificates, only on or after the first Distribution Date on which the aggregate Stated Principal Balances of the Mortgage Loans, the Trust Subordinate Companion Loans and the portion of any REO Loans held by the Trust is less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage Loans (solely for the purposes of this calculation, if such right is being exercised after December 2027 and the 237 East Fordham Road Mortgage Loan is still an asset of the Trust, then such Mortgage Loan will be excluded from the then-aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate Companion Loans and from the aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate Companion Loans as of the Cut-off Date) as set forth in the Pooling and Servicing Agreement.

Following the date on which the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class A-S, Class X-A, Class X-B, Class X-E, Class B and Class C Regular Interests have been reduced to zero (and provided that there is only one Holder (or multiple Holders acting in unanimity) of the then-outstanding Certificates (other than the Class Z and Class R Certificates)), the Sole Certificateholder shall have the right, with the consent of the Master Servicer, to exchange all of its Certificates (other than the Class Z and Class R Certificates) together with the payment or deemed payment of the Termination Purchase Amount for all of the Mortgage Loans, the Trust Subordinate Companion Loans and each REO Property remaining in the Trust Fund pursuant to the terms of the Pooling and Servicing Agreement.

The obligations created by the Pooling and Servicing Agreement and the Trust created thereby (other than the obligation of the Certificate Administrator to make payments to

A-26-12 

Certificateholders as provided for in the Pooling and Servicing Agreement), shall terminate upon reduction of the Certificate Balances of all the Certificates to zero (including, without limitation, any such final payment resulting from a termination of the Trust due to a sale of its property) pursuant to the terms of the Pooling and Servicing Agreement. In no event, however, will the Trust created by the Pooling and Servicing Agreement continue beyond the expiration of 21 years from the death of the last survivor of the descendants of Joseph P. Kennedy, the late Ambassador of the United States to the Court of St. James, living on the date hereof.

Unless the certificate of authentication hereon has been executed by the Authenticating Agent, by manual signature, this Certificate shall not be entitled to any benefit under the Pooling and Servicing Agreement or be valid for any purpose. The Certificate Registrar has executed this Certificate on behalf of the Trust as Certificate Registrar under the Pooling and Servicing Agreement and makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates, the Mortgage Loans or the Trust Subordinate Companion Loans.

This Certificate is issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of November 1, 2017 (the “Pooling and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities Corp., as Depositor, Wells Fargo Bank, National Association, as Certificate Administrator and as Trustee, Park Bridge Lender Services LLC, as Operating Advisor and as Asset Representations Reviewer, KeyBank National Association, as Master Servicer, and CWCapital Asset Management LLC, as Special Servicer. To the extent not defined herein, capitalized terms used herein shall have the meanings assigned thereto in the Pooling and Servicing Agreement.

This Certificate represents beneficial ownership of a “regular interest” in a “real estate mortgage investment conduit,” as those terms are defined, respectively, in Sections 860G(a)(1) and 860D of the Internal Revenue Code of 1986, as amended.

The Certificate Administrator makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates, the Mortgage Loans or the Trust Subordinate Companion Loans and has executed this Certificate in its limited capacity as Certificate Administrator under the Pooling and Servicing Agreement.

Pursuant to the terms of the Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution on any Certificate), on the 4th Business Day following the determination date of each month, commencing in December 2017 (each such date, a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related Record Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this Certificate) of that portion of the aggregate amount of interest then distributable, if any, allocable to the Class UES-X Certificates for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement.

Interest accrued on this Certificate during an Interest Accrual Period, plus the aggregate unpaid Interest Shortfall with respect to this Certificate, if any, will be payable on the related Distribution Date to the extent provided in the Pooling and Servicing Agreement. The “Interest Accrual Period” with respect to any Distribution Date and with respect to the Class UES-X Certificates is the calendar month immediately preceding the month in which such Distribution Date occurs and is assumed to consist of 30 days.

All distributions (other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons in whose names the Certificates are registered at the close of business on each Record Date, which will be the close of business on the last Business Day of the month immediately preceding the month in which such Distribution Date occurs. Distributions are required to be made (a) by wire transfer of immediately available funds to the account of such Certificateholder at a bank or other entity having appropriate facilities

A-26-4 

therefor, if such Certificateholder provided the Certificate Administrator with written wiring instructions no less than five Business Days prior to the related Record Date (which wiring instructions may be in the form of a standing order applicable to all subsequent Distribution Dates), or otherwise (b) by check mailed to such Certificateholder at its address in the Certificate Register. The final distribution on each Certificate will be made in like manner, but only upon presentment and surrender of such Certificate at the offices of the Certificate Registrar or such other location specified in the notice to Certificateholders of such final distribution.

Any funds not distributed to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure of such Certificateholders to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited to the account or accounts of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been given pursuant to Section 4.01(l) of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within six months after the time specified in such notice, the Certificate Administrator shall mail a second notice to the remaining non tendering Certificateholders to surrender their Certificates for cancellation in order to receive the final distribution with respect thereto. If within one year after the second notice all such Certificates shall not have been surrendered for cancellation, the Certificate Administrator, directly or through an agent, shall take such steps to contact the remaining non tendering Certificateholders concerning the surrender of their Certificates as it shall deem appropriate and subject to escheatment and other applicable laws. The costs and expenses of holding such funds in trust and of contacting such Certificateholders following the first anniversary of the delivery of such second notice to the non-tendering Certificateholders shall be paid out of such funds. No interest shall accrue or be payable to any Certificateholder on any amount held in trust under the Pooling and Servicing Agreement by the Certificate Administrator as a result of such Certificateholder’s failure to surrender its Certificate(s) for final payment thereof in accordance with Section 4.01(l) of the Pooling and Servicing Agreement.

This Certificate is limited in right of payment to, among other things, certain collections and recoveries in respect of the Y&L Towers Trust Subordinate Companion Loan, as more specifically set forth herein and in the Pooling and Servicing Agreement.

As provided in the Pooling and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject to the Pooling and Servicing Agreement (including any Qualified Substitute Mortgage Loan replacing a removed Mortgage Loan) and the Trust Subordinate Companion Loans, together with the Mortgage Files relating thereto (subject to, in the case of a Serviced Whole Loan, the interests of the related Serviced Companion Noteholder in the related Mortgage File); (ii) all scheduled or unscheduled payments on or collections in respect of the Mortgage Loans and the Trust Subordinate Companion Loans due after the Cut-off Date (or with respect to a Qualified Substitute Mortgage Loan, the Due Date in the month of substitution); (iii) any REO Property (to the extent of the Trust’s interest therein) or the Trust’s beneficial interest in the Mortgaged Property securing a Non Serviced Whole Loan acquired under the related Non-Serviced PSA; (iv) all revenues received in respect of any REO Property (to the extent of the Trust’s interest therein); (v) the Master Servicer’s, the Special Servicer’s, the Certificate Administrator’s and the Trustee’s rights under the insurance policies with respect to the Mortgage Loans and the Trust Subordinate Companion Loans required to be maintained pursuant to the Pooling and Servicing Agreement and any proceeds thereof (to the

A-26-5 

extent of the Trust’s interest therein); (vi) any Assignment of Leases and any security agreements (to the extent of the Trust’s interest therein); (vii) any letters of credit, indemnities, guaranties or lease enhancement policies given as additional security for any related Mortgage Loans or Trust Subordinate Companion Loans (to the extent of the Trust’s interest therein); (viii) all assets deposited in the Loss of Value Reserve Fund and the Servicing Accounts (to the extent of the Trust’s interest therein), amounts on deposit in the Collection Account (to the extent of the Trust’s interest therein), the Lower-Tier REMIC Distribution Account, the Upper-Tier REMIC Distribution Account, the Trust Subordinate Companion Loan REMIC Distribution Accounts, the Regular Interest Distribution Account, the Excess Interest Distribution Account, the Interest Reserve Account, the Gain-on-Sale Reserve Account (to the extent of the Trust’s interest therein) and any REO Account (to the extent of the Trust’s interest therein), including any reinvestment income, as applicable; (ix) any Environmental Indemnity Agreements (to the extent of the Trust’s interest therein); (x) the rights and remedies of the Depositor under each Mortgage Loan Purchase Agreement (to the extent transferred to the Trustee); (xi) the Lower-Tier Regular Interests; (xii) the Trust Subordinate Companion Loan REMIC Regular Interests; and (xiii) the proceeds of the foregoing (other than any interest earned on deposits in the lock-box accounts, cash collateral accounts, escrow accounts and any reserve accounts, to the extent such interest belongs to the related Mortgagor).

This Certificate does not purport to summarize the Pooling and Servicing Agreement, and reference is made to the Pooling and Servicing Agreement for the interests, rights, benefits, obligations and duties evidenced hereby, and the limitations thereon, and the rights, duties and immunities of the Certificate Administrator and Trustee.

As provided in the Pooling and Servicing Agreement, subject to certain restrictions on transfer set forth therein, upon surrender for registration of transfer of any Certificate, the Certificate Administrator shall execute, authenticate and deliver, in the name of the designated transferee or transferees, one or more new Certificates in authorized denominations, in like aggregate interest and of the same Class.

Prior to due presentation of this Certificate for registration of transfer, the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Certificate Registrar, and any agent of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate Registrar may treat the Person in whose name any Certificate is registered as the owner of such Certificate for the purpose of receiving distributions as provided in the Pooling and Servicing Agreement and for all other purposes whatsoever, and none of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Certificate Registrar, or any agent of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate Registrar shall be affected by any notice to the contrary.

(v) to modify, eliminate or add to the provisions of Section 5.03(o) of the Pooling and Servicing Agreement or any other provision of the Pooling and Servicing Agreement restricting transfer of the Class R Certificates; provided the Depositor has determined that such change shall not, as evidenced by an Opinion of Counsel, cause the Trust, any Trust REMIC or any of the Certificateholders (other than the Transferor) to be subject to a federal tax caused by a Transfer to a Person that is a Disqualified Organization or a Non-U.S. Tax Person;

(vi) to revise or add any other provisions with respect to matters or questions arising under the Pooling and Servicing Agreement or any other change; provided that the required action shall not adversely affect in any material respect the interests of any Certificateholder (including, for the avoidance of doubt, any Holder of a VRR Interest, a Y&L Towers VRR Interest or a Standard Highline VRR Interest) or any holder of a Serviced Pari Passu Companion Loan not consenting to such revision or addition, as evidenced in writing by an Opinion of Counsel, at the expense of the party requesting such amendment or as evidenced by a Rating Agency Confirmation from each of the Rating Agencies with respect to such amendment or supplement and confirmation of the applicable rating agencies that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings of any class of Serviced Companion Loan Securities, if any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement);

(viii) to modify the provisions of Sections 3.05 and 3.17 of the Pooling and Servicing Agreement (with respect to reimbursement of Nonrecoverable Advances and Workout-Delayed Reimbursement Amounts) if (a) the

A-26-8 

Depositor, the Master Servicer, the Trustee and, for so long as a Control Termination Event has not occurred and is not continuing and, with respect to any Mortgage Loans other than any Excluded Loan, as to the Directing Holder or, in the case of the Directing Certificateholder, the Holder of a majority of the Controlling Class, the Directing Holder, determine that the commercial mortgage backed securities industry standard for such provisions has changed, in order to conform to such industry standard, (b) such modification does not adversely affect the status of any Trust REMIC as a REMIC or the status of the Grantor Trust as a grantor trust under the relevant provisions of the Code, as evidenced by an Opinion of Counsel and (c) each Rating Agency has delivered a Rating Agency Confirmation and, with regard to any class of Serviced Companion Loan Securities, the applicable rating agencies have delivered a confirmation that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement);

(ix) to modify the procedures of the Pooling and Servicing Agreement relating to compliance with Rule 17g-5 of the Exchange Act; provided that such amendment shall not adversely affect in any material respects the interests of any Certificateholders (including, for the avoidance of doubt, any Holders of a VRR Interest, a Y&L Towers VRR Interest or a Standard Highline VRR Interest), as evidenced by (x) an Opinion of Counsel or (y) if any Certificate is then rated, receipt of Rating Agency Confirmation from each Rating Agency rating such Certificates; and provided, further, that the Certificate Administrator shall give notice of any such amendment to the 17g-5 Information Provider for posting to the 17g-5 Information Provider’s Website pursuant to Section 3.13(c) of the Pooling and Servicing Agreement and the Certificate Administrator shall post such notice to the Certificate Administrator’s Website;

Notwithstanding the foregoing, no such amendment (A) may change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations of any

A-26-9 

Mortgage Loan Seller under any Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller or (B) may materially and adversely affect the holders of a Companion Loan without such Companion Holder’s consent.

The Pooling and Servicing Agreement may also be amended from time to time by the parties thereto with the consent of the Holders of Certificates of each Class affected by such amendment (including, for the avoidance of doubt, any Holders of the VRR Interest, the Y&L Towers VRR Interest or the Standard Highline VRR Interest to the extent any such amendment would adversely affect the rights of such Certificateholders) evidencing in the aggregate not less than a majority of the aggregate Percentage Interests constituting the Class for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of the Pooling and Servicing Agreement or of modifying in any manner the rights of the Holders of Certificates of such Class; provided, however, that no such amendment shall:

(i) reduce in any manner the amount of, or delay the timing of, payments received on the Mortgage Loans or the Trust Subordinate Companion Loans that are required to be distributed on a Certificate of any class without the consent of the Holder of the Certificate or which are required to be distributed to a Companion Holder without the consent of such Companion Holder; or

(ii) reduce the aforesaid percentage of Certificates of any Class the Holders of which are required to consent to any such amendment or remove the requirement to obtain consent of any Companion Holder or Holder of Loan-Specific Certificates, in any such case, without the consent of the Holders of all Certificates of such Class then-outstanding or such Companion Holders, as applicable; or

(iii) adversely affect the Voting Rights of any Class of Certificates without the consent of the Holders of all Certificates of such Class then outstanding; or

(iv) change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations of any Mortgage Loan Seller under such Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller; or

(v) amend the Servicing Standard without the consent of 100% of the Certificateholders or receipt of Rating Agency Confirmation from each Rating Agency and confirmation of the applicable rating agencies that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings of any Serviced Companion Loan Securities, if any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be

A-26-10 

considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement) and, if required under the related Intercreditor Agreement, the consent of the holder of any AB Subordinate Companion Loan for each Serviced AB Whole Loan.

Notwithstanding the foregoing, none of the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Depositor, the Master Servicer nor the Special Servicer will be required to consent to any amendment to the Pooling and Servicing Agreement without having first received an Opinion of Counsel (at the Trust’s expense) to the effect that such amendment is permitted under the Pooling and Servicing Agreement, that all conditions precedent have been satisfied and that such amendment or the exercise of any power granted to the Master Servicer, the Special Servicer, the Depositor, the Trustee, the Certificate Administrator, the Operating Advisor, the Asset Representations Reviewer or any other specified person in accordance with such amendment will not result in the imposition of a tax on any portion of the Trust Fund or any Trust REMIC, or cause any Trust REMIC to fail to qualify as a REMIC or cause the Grantor Trust to fail to qualify as a grantor trust under the relevant provisions of the Code.

The Holders of the majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates may, in that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the Certificate Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage Loans (and all property acquired through exercise of remedies in respect of any related Mortgage Loan), the Trust Subordinate Companion Loans and the Trust’s portion of each REO Property remaining in the Trust Fund, and thereby effect termination of the Trust and early retirement of the then-outstanding Certificates, only on or after the first Distribution Date on which the aggregate Stated Principal Balances of the Mortgage Loans, the Trust Subordinate Companion Loans and the portion of any REO Loans held by the Trust is less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage Loans (solely for the purposes of this calculation, if such right is being exercised after December 2027 and the 237 East Fordham Road Mortgage Loan is still an asset of the Trust, then such Mortgage Loan will be excluded from the then-aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate Companion Loans and from the aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate Companion Loans as of the Cut-off Date) as set forth in the Pooling and Servicing Agreement.

Following the date on which the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class A-S, Class X-A, Class X-B, Class X-E, Class B and Class C Regular Interests have been reduced to zero (and provided that there is only one Holder (or multiple Holders acting in unanimity) of the then-outstanding Certificates (other than the Class Z and Class R Certificates)), the Sole Certificateholder shall have the right, with the consent of the Master Servicer, to exchange all of its Certificates (other than the Class Z and Class R Certificates) together with the payment or deemed payment of the Termination Purchase Amount for all of the Mortgage Loans, the Trust Subordinate Companion Loans and each REO Property remaining in the Trust Fund pursuant to the terms of the Pooling and Servicing Agreement.

The obligations created by the Pooling and Servicing Agreement and the Trust created thereby (other than the obligation of the Certificate Administrator to make payments to

A-26-11 

Certificateholders as provided for in the Pooling and Servicing Agreement), shall terminate upon reduction of the Certificate Balances of all the Certificates to zero (including, without limitation, any such final payment resulting from a termination of the Trust due to a sale of its property) pursuant to the terms of the Pooling and Servicing Agreement. In no event, however, will the Trust created by the Pooling and Servicing Agreement continue beyond the expiration of 21 years from the death of the last survivor of the descendants of Joseph P. Kennedy, the late Ambassador of the United States to the Court of St. James, living on the date hereof.

Unless the certificate of authentication hereon has been executed by the Authenticating Agent, by manual signature, this Certificate shall not be entitled to any benefit under the Pooling and Servicing Agreement or be valid for any purpose. The Certificate Registrar has executed this Certificate on behalf of the Trust as Certificate Registrar under the Pooling and Servicing Agreement and makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates, the Mortgage Loans or the Trust Subordinate Companion Loans.

This Certificate is issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of November 1, 2017 (the “Pooling and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities Corp., as Depositor, Wells Fargo Bank, National Association, as Certificate Administrator and as Trustee, Park Bridge Lender Services LLC, as Operating Advisor and as Asset Representations Reviewer, KeyBank National Association, as Master Servicer, and CWCapital Asset Management LLC, as Special Servicer. To the extent not defined herein, capitalized terms used herein shall have the meanings assigned thereto in the Pooling and Servicing Agreement.

This Certificate represents beneficial ownership of a “regular interest” in a “real estate mortgage investment conduit,” as those terms are defined, respectively, in Sections 860G(a)(1) and 860D of the Internal Revenue Code of 1986, as amended.

The Certificate Administrator makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates, the Mortgage Loans or the Trust Subordinate Companion Loans and has executed this Certificate in its limited capacity as Certificate Administrator under the Pooling and Servicing Agreement.

Pursuant to the terms of the Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution on any Certificate), on the 4th Business Day following the determination date of each month, commencing in December 2017 (each such date, a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related Record Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this Certificate) of that portion of the aggregate amount of principal and interest then distributable, if any, allocable to the Class STN-A Certificates for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement.

Interest accrued on this Certificate during an Interest Accrual Period, plus the aggregate unpaid Interest Shortfall with respect to this Certificate, if any, will be payable on the related Distribution Date to the extent provided in the Pooling and Servicing Agreement. The “Interest Accrual Period” with respect to any Distribution Date and with respect to the Class STN-A Certificates is the calendar month immediately preceding the month in which such Distribution Date occurs and is assumed to consist of 30 days.

All distributions (other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons in whose names the Certificates are registered at the close of business on each Record Date, which will be the close of business on the last Business Day of the month immediately preceding the month in which such Distribution Date occurs. Distributions are required to be made (a) by wire transfer of immediately available funds to the account of such Certificateholder at a bank or other entity having appropriate facilities

A-26-4 

therefor, if such Certificateholder provided the Certificate Administrator with written wiring instructions no less than five Business Days prior to the related Record Date (which wiring instructions may be in the form of a standing order applicable to all subsequent Distribution Dates), or otherwise (b) by check mailed to such Certificateholder at its address in the Certificate Register. The final distribution on each Certificate will be made in like manner, but only upon presentment and surrender of such Certificate at the offices of the Certificate Registrar or such other location specified in the notice to Certificateholders of such final distribution.

Any funds not distributed to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure of such Certificateholders to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited to the account or accounts of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been given pursuant to Section 4.01(l) of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within six months after the time specified in such notice, the Certificate Administrator shall mail a second notice to the remaining non tendering Certificateholders to surrender their Certificates for cancellation in order to receive the final distribution with respect thereto. If within one year after the second notice all such Certificates shall not have been surrendered for cancellation, the Certificate Administrator, directly or through an agent, shall take such steps to contact the remaining non tendering Certificateholders concerning the surrender of their Certificates as it shall deem appropriate and subject to escheatment and other applicable laws. The costs and expenses of holding such funds in trust and of contacting such Certificateholders following the first anniversary of the delivery of such second notice to the non-tendering Certificateholders shall be paid out of such funds. No interest shall accrue or be payable to any Certificateholder on any amount held in trust under the Pooling and Servicing Agreement by the Certificate Administrator as a result of such Certificateholder’s failure to surrender its Certificate(s) for final payment thereof in accordance with Section 4.01(l) of the Pooling and Servicing Agreement.

This Certificate is limited in right of payment to, among other things, certain collections and recoveries in respect of the Standard Highline Trust Subordinate Companion Loan, as more specifically set forth herein and in the Pooling and Servicing Agreement.

As provided in the Pooling and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject to the Pooling and Servicing Agreement (including any Qualified Substitute Mortgage Loan replacing a removed Mortgage Loan) and the Trust Subordinate Companion Loans, together with the Mortgage Files relating thereto (subject to, in the case of a Serviced Whole Loan, the interests of the related Serviced Companion Noteholder in the related Mortgage File); (ii) all scheduled or unscheduled payments on or collections in respect of the Mortgage Loans and the Trust Subordinate Companion Loans due after the Cut-off Date (or with respect to a Qualified Substitute Mortgage Loan, the Due Date in the month of substitution); (iii) any REO Property (to the extent of the Trust’s interest therein) or the Trust’s beneficial interest in the Mortgaged Property securing a Non Serviced Whole Loan acquired under the related Non-Serviced PSA; (iv) all revenues received in respect of any REO Property (to the extent of the Trust’s interest therein); (v) the Master Servicer’s, the Special Servicer’s, the Certificate Administrator’s and the Trustee’s rights under the insurance policies with respect to the Mortgage Loans and the Trust Subordinate Companion Loans required to be maintained pursuant to the Pooling and Servicing Agreement and any proceeds thereof (to the

A-26-5 

extent of the Trust’s interest therein); (vi) any Assignment of Leases and any security agreements (to the extent of the Trust’s interest therein); (vii) any letters of credit, indemnities, guaranties or lease enhancement policies given as additional security for any related Mortgage Loans or Trust Subordinate Companion Loans (to the extent of the Trust’s interest therein); (viii) all assets deposited in the Loss of Value Reserve Fund and the Servicing Accounts (to the extent of the Trust’s interest therein), amounts on deposit in the Collection Account (to the extent of the Trust’s interest therein), the Lower-Tier REMIC Distribution Account, the Upper-Tier REMIC Distribution Account, the Trust Subordinate Companion Loan REMIC Distribution Accounts, the Regular Interest Distribution Account, the Excess Interest Distribution Account, the Interest Reserve Account, the Gain-on-Sale Reserve Account (to the extent of the Trust’s interest therein) and any REO Account (to the extent of the Trust’s interest therein), including any reinvestment income, as applicable; (ix) any Environmental Indemnity Agreements (to the extent of the Trust’s interest therein); (x) the rights and remedies of the Depositor under each Mortgage Loan Purchase Agreement (to the extent transferred to the Trustee); (xi) the Lower-Tier Regular Interests; (xii) the Trust Subordinate Companion Loan REMIC Regular Interests; and (xiii) the proceeds of the foregoing (other than any interest earned on deposits in the lock-box accounts, cash collateral accounts, escrow accounts and any reserve accounts, to the extent such interest belongs to the related Mortgagor).

This Certificate does not purport to summarize the Pooling and Servicing Agreement, and reference is made to the Pooling and Servicing Agreement for the interests, rights, benefits, obligations and duties evidenced hereby, and the limitations thereon, and the rights, duties and immunities of the Certificate Administrator and Trustee.

As provided in the Pooling and Servicing Agreement, subject to certain restrictions on transfer set forth therein, upon surrender for registration of transfer of any Certificate, the Certificate Administrator shall execute, authenticate and deliver, in the name of the designated transferee or transferees, one or more new Certificates in authorized denominations, in like aggregate interest and of the same Class.

Prior to due presentation of this Certificate for registration of transfer, the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Certificate Registrar, and any agent of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate Registrar may treat the Person in whose name any Certificate is registered as the owner of such Certificate for the purpose of receiving distributions as provided in the Pooling and Servicing Agreement and for all other purposes whatsoever, and none of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Certificate Registrar, or any agent of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate Registrar shall be affected by any notice to the contrary.

Notwithstanding the foregoing, no such amendment (A) may change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations of any

A-26-9 

Mortgage Loan Seller under any Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller or (B) may materially and adversely affect the holders of a Companion Loan without such Companion Holder’s consent.

The Pooling and Servicing Agreement may also be amended from time to time by the parties thereto with the consent of the Holders of Certificates of each Class affected by such amendment (including, for the avoidance of doubt, any Holders of the VRR Interest, the Y&L Towers VRR Interest or the Standard Highline VRR Interest to the extent any such amendment would adversely affect the rights of such Certificateholders) evidencing in the aggregate not less than a majority of the aggregate Percentage Interests constituting the Class for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of the Pooling and Servicing Agreement or of modifying in any manner the rights of the Holders of Certificates of such Class; provided, however, that no such amendment shall:

(i) reduce in any manner the amount of, or delay the timing of, payments received on the Mortgage Loans or the Trust Subordinate Companion Loans that are required to be distributed on a Certificate of any class without the consent of the Holder of the Certificate or which are required to be distributed to a Companion Holder without the consent of such Companion Holder; or

(ii) reduce the aforesaid percentage of Certificates of any Class the Holders of which are required to consent to any such amendment or remove the requirement to obtain consent of any Companion Holder or Holder of Loan-Specific Certificates, in any such case, without the consent of the Holders of all Certificates of such Class then-outstanding or such Companion Holders, as applicable; or

(iii) adversely affect the Voting Rights of any Class of Certificates without the consent of the Holders of all Certificates of such Class then outstanding; or

(iv) change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations of any Mortgage Loan Seller under such Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller; or

(v) amend the Servicing Standard without the consent of 100% of the Certificateholders or receipt of Rating Agency Confirmation from each Rating Agency and confirmation of the applicable rating agencies that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings of any Serviced Companion Loan Securities, if any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be

A-26-10 

considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement) and, if required under the related Intercreditor Agreement, the consent of the holder of any AB Subordinate Companion Loan for each Serviced AB Whole Loan.

Notwithstanding the foregoing, none of the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Depositor, the Master Servicer nor the Special Servicer will be required to consent to any amendment to the Pooling and Servicing Agreement without having first received an Opinion of Counsel (at the Trust’s expense) to the effect that such amendment is permitted under the Pooling and Servicing Agreement, that all conditions precedent have been satisfied and that such amendment or the exercise of any power granted to the Master Servicer, the Special Servicer, the Depositor, the Trustee, the Certificate Administrator, the Operating Advisor, the Asset Representations Reviewer or any other specified person in accordance with such amendment will not result in the imposition of a tax on any portion of the Trust Fund or any Trust REMIC, or cause any Trust REMIC to fail to qualify as a REMIC or cause the Grantor Trust to fail to qualify as a grantor trust under the relevant provisions of the Code.

The Holders of the majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates may, in that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the Certificate Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage Loans (and all property acquired through exercise of remedies in respect of any related Mortgage Loan), the Trust Subordinate Companion Loans and the Trust’s portion of each REO Property remaining in the Trust Fund, and thereby effect termination of the Trust and early retirement of the then-outstanding Certificates, only on or after the first Distribution Date on which the aggregate Stated Principal Balances of the Mortgage Loans, the Trust Subordinate Companion Loans and the portion of any REO Loans held by the Trust is less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage Loans (solely for the purposes of this calculation, if such right is being exercised after December 2027 and the 237 East Fordham Road Mortgage Loan is still an asset of the Trust, then such Mortgage Loan will be excluded from the then-aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate Companion Loans and from the aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate Companion Loans as of the Cut-off Date) as set forth in the Pooling and Servicing Agreement.

Following the date on which the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class A-S, Class X-A, Class X-B, Class X-E, Class B and Class C Regular Interests have been reduced to zero (and provided that there is only one Holder (or multiple Holders acting in unanimity) of the then-outstanding Certificates (other than the Class Z and Class R Certificates)), the Sole Certificateholder shall have the right, with the consent of the Master Servicer, to exchange all of its Certificates (other than the Class Z and Class R Certificates) together with the payment or deemed payment of the Termination Purchase Amount for all of the Mortgage Loans, the Trust Subordinate Companion Loans and each REO Property remaining in the Trust Fund pursuant to the terms of the Pooling and Servicing Agreement.

The obligations created by the Pooling and Servicing Agreement and the Trust created thereby (other than the obligation of the Certificate Administrator to make payments to

A-26-11 

Certificateholders as provided for in the Pooling and Servicing Agreement), shall terminate upon reduction of the Certificate Balances of all the Certificates to zero (including, without limitation, any such final payment resulting from a termination of the Trust due to a sale of its property) pursuant to the terms of the Pooling and Servicing Agreement. In no event, however, will the Trust created by the Pooling and Servicing Agreement continue beyond the expiration of 21 years from the death of the last survivor of the descendants of Joseph P. Kennedy, the late Ambassador of the United States to the Court of St. James, living on the date hereof.

Unless the certificate of authentication hereon has been executed by the Authenticating Agent, by manual signature, this Certificate shall not be entitled to any benefit under the Pooling and Servicing Agreement or be valid for any purpose. The Certificate Registrar has executed this Certificate on behalf of the Trust as Certificate Registrar under the Pooling and Servicing Agreement and makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates, the Mortgage Loans or the Trust Subordinate Companion Loans.

This Certificate is issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of November 1, 2017 (the “Pooling and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities Corp., as Depositor, Wells Fargo Bank, National Association, as Certificate Administrator and as Trustee, Park Bridge Lender Services LLC, as Operating Advisor and as Asset Representations Reviewer, KeyBank National Association, as Master Servicer, and CWCapital Asset Management LLC, as Special Servicer. To the extent not defined herein, capitalized terms used herein shall have the meanings assigned thereto in the Pooling and Servicing Agreement.

This Certificate represents beneficial ownership of a “regular interest” in a “real estate mortgage investment conduit,” as those terms are defined, respectively, in Sections 860G(a)(1) and 860D of the Internal Revenue Code of 1986, as amended.

The Certificate Administrator makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates, the Mortgage Loans or the Trust Subordinate Companion Loans and has executed this Certificate in its limited capacity as Certificate Administrator under the Pooling and Servicing Agreement.

Pursuant to the terms of the Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution on any Certificate), on the 4th Business Day following the determination date of each month, commencing in December 2017 (each such date, a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related Record Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this Certificate) of that portion of the aggregate amount of principal and interest then distributable, if any, allocable to the Class STN-B Certificates for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement.

Interest accrued on this Certificate during an Interest Accrual Period, plus the aggregate unpaid Interest Shortfall with respect to this Certificate, if any, will be payable on the related Distribution Date to the extent provided in the Pooling and Servicing Agreement. The “Interest Accrual Period” with respect to any Distribution Date and with respect to the Class STN-B Certificates is the calendar month immediately preceding the month in which such Distribution Date occurs and is assumed to consist of 30 days.

All distributions (other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons in whose names the Certificates are registered at the close of business on each Record Date, which will be the close of business on the last Business Day of the month immediately preceding the month in which such Distribution Date occurs. Distributions are required to be made (a) by wire transfer of immediately available funds to the account of such Certificateholder at a bank or other entity having appropriate facilities

A-26-4 

therefor, if such Certificateholder provided the Certificate Administrator with written wiring instructions no less than five Business Days prior to the related Record Date (which wiring instructions may be in the form of a standing order applicable to all subsequent Distribution Dates), or otherwise (b) by check mailed to such Certificateholder at its address in the Certificate Register. The final distribution on each Certificate will be made in like manner, but only upon presentment and surrender of such Certificate at the offices of the Certificate Registrar or such other location specified in the notice to Certificateholders of such final distribution.

Any funds not distributed to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure of such Certificateholders to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited to the account or accounts of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been given pursuant to Section 4.01(l) of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within six months after the time specified in such notice, the Certificate Administrator shall mail a second notice to the remaining non tendering Certificateholders to surrender their Certificates for cancellation in order to receive the final distribution with respect thereto. If within one year after the second notice all such Certificates shall not have been surrendered for cancellation, the Certificate Administrator, directly or through an agent, shall take such steps to contact the remaining non tendering Certificateholders concerning the surrender of their Certificates as it shall deem appropriate and subject to escheatment and other applicable laws. The costs and expenses of holding such funds in trust and of contacting such Certificateholders following the first anniversary of the delivery of such second notice to the non-tendering Certificateholders shall be paid out of such funds. No interest shall accrue or be payable to any Certificateholder on any amount held in trust under the Pooling and Servicing Agreement by the Certificate Administrator as a result of such Certificateholder’s failure to surrender its Certificate(s) for final payment thereof in accordance with Section 4.01(l) of the Pooling and Servicing Agreement.

This Certificate is limited in right of payment to, among other things, certain collections and recoveries in respect of the Standard Highline Trust Subordinate Companion Loan, as more specifically set forth herein and in the Pooling and Servicing Agreement.

As provided in the Pooling and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject to the Pooling and Servicing Agreement (including any Qualified Substitute Mortgage Loan replacing a removed Mortgage Loan) and the Trust Subordinate Companion Loans, together with the Mortgage Files relating thereto (subject to, in the case of a Serviced Whole Loan, the interests of the related Serviced Companion Noteholder in the related Mortgage File); (ii) all scheduled or unscheduled payments on or collections in respect of the Mortgage Loans and the Trust Subordinate Companion Loans due after the Cut-off Date (or with respect to a Qualified Substitute Mortgage Loan, the Due Date in the month of substitution); (iii) any REO Property (to the extent of the Trust’s interest therein) or the Trust’s beneficial interest in the Mortgaged Property securing a Non Serviced Whole Loan acquired under the related Non-Serviced PSA; (iv) all revenues received in respect of any REO Property (to the extent of the Trust’s interest therein); (v) the Master Servicer’s, the Special Servicer’s, the Certificate Administrator’s and the Trustee’s rights under the insurance policies with respect to the Mortgage Loans and the Trust Subordinate Companion Loans required to be maintained pursuant to the Pooling and Servicing Agreement and any proceeds thereof (to the

A-26-5 

extent of the Trust’s interest therein); (vi) any Assignment of Leases and any security agreements (to the extent of the Trust’s interest therein); (vii) any letters of credit, indemnities, guaranties or lease enhancement policies given as additional security for any related Mortgage Loans or Trust Subordinate Companion Loans (to the extent of the Trust’s interest therein); (viii) all assets deposited in the Loss of Value Reserve Fund and the Servicing Accounts (to the extent of the Trust’s interest therein), amounts on deposit in the Collection Account (to the extent of the Trust’s interest therein), the Lower-Tier REMIC Distribution Account, the Upper-Tier REMIC Distribution Account, the Trust Subordinate Companion Loan REMIC Distribution Accounts, the Regular Interest Distribution Account, the Excess Interest Distribution Account, the Interest Reserve Account, the Gain-on-Sale Reserve Account (to the extent of the Trust’s interest therein) and any REO Account (to the extent of the Trust’s interest therein), including any reinvestment income, as applicable; (ix) any Environmental Indemnity Agreements (to the extent of the Trust’s interest therein); (x) the rights and remedies of the Depositor under each Mortgage Loan Purchase Agreement (to the extent transferred to the Trustee); (xi) the Lower-Tier Regular Interests; (xii) the Trust Subordinate Companion Loan REMIC Regular Interests; and (xiii) the proceeds of the foregoing (other than any interest earned on deposits in the lock-box accounts, cash collateral accounts, escrow accounts and any reserve accounts, to the extent such interest belongs to the related Mortgagor).

This Certificate does not purport to summarize the Pooling and Servicing Agreement, and reference is made to the Pooling and Servicing Agreement for the interests, rights, benefits, obligations and duties evidenced hereby, and the limitations thereon, and the rights, duties and immunities of the Certificate Administrator and Trustee.

As provided in the Pooling and Servicing Agreement, subject to certain restrictions on transfer set forth therein, upon surrender for registration of transfer of any Certificate, the Certificate Administrator shall execute, authenticate and deliver, in the name of the designated transferee or transferees, one or more new Certificates in authorized denominations, in like aggregate interest and of the same Class.

Prior to due presentation of this Certificate for registration of transfer, the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Certificate Registrar, and any agent of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate Registrar may treat the Person in whose name any Certificate is registered as the owner of such Certificate for the purpose of receiving distributions as provided in the Pooling and Servicing Agreement and for all other purposes whatsoever, and none of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Certificate Registrar, or any agent of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate Registrar shall be affected by any notice to the contrary.

Notwithstanding the foregoing, no such amendment (A) may change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations of any

A-26-9 

Mortgage Loan Seller under any Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller or (B) may materially and adversely affect the holders of a Companion Loan without such Companion Holder’s consent.

The Pooling and Servicing Agreement may also be amended from time to time by the parties thereto with the consent of the Holders of Certificates of each Class affected by such amendment (including, for the avoidance of doubt, any Holders of the VRR Interest, the Y&L Towers VRR Interest or the Standard Highline VRR Interest to the extent any such amendment would adversely affect the rights of such Certificateholders) evidencing in the aggregate not less than a majority of the aggregate Percentage Interests constituting the Class for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of the Pooling and Servicing Agreement or of modifying in any manner the rights of the Holders of Certificates of such Class; provided, however, that no such amendment shall:

(i) reduce in any manner the amount of, or delay the timing of, payments received on the Mortgage Loans or the Trust Subordinate Companion Loans that are required to be distributed on a Certificate of any class without the consent of the Holder of the Certificate or which are required to be distributed to a Companion Holder without the consent of such Companion Holder; or

(ii) reduce the aforesaid percentage of Certificates of any Class the Holders of which are required to consent to any such amendment or remove the requirement to obtain consent of any Companion Holder or Holder of Loan-Specific Certificates, in any such case, without the consent of the Holders of all Certificates of such Class then-outstanding or such Companion Holders, as applicable; or

(v) amend the Servicing Standard without the consent of 100% of the Certificateholders or receipt of Rating Agency Confirmation from each Rating Agency and confirmation of the applicable rating agencies that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings of any Serviced Companion Loan Securities, if any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be

A-26-10 

considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement) and, if required under the related Intercreditor Agreement, the consent of the holder of any AB Subordinate Companion Loan for each Serviced AB Whole Loan.

Notwithstanding the foregoing, none of the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Depositor, the Master Servicer nor the Special Servicer will be required to consent to any amendment to the Pooling and Servicing Agreement without having first received an Opinion of Counsel (at the Trust’s expense) to the effect that such amendment is permitted under the Pooling and Servicing Agreement, that all conditions precedent have been satisfied and that such amendment or the exercise of any power granted to the Master Servicer, the Special Servicer, the Depositor, the Trustee, the Certificate Administrator, the Operating Advisor, the Asset Representations Reviewer or any other specified person in accordance with such amendment will not result in the imposition of a tax on any portion of the Trust Fund or any Trust REMIC, or cause any Trust REMIC to fail to qualify as a REMIC or cause the Grantor Trust to fail to qualify as a grantor trust under the relevant provisions of the Code.

The Holders of the majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates may, in that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the Certificate Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage Loans (and all property acquired through exercise of remedies in respect of any related Mortgage Loan), the Trust Subordinate Companion Loans and the Trust’s portion of each REO Property remaining in the Trust Fund, and thereby effect termination of the Trust and early retirement of the then-outstanding Certificates, only on or after the first Distribution Date on which the aggregate Stated Principal Balances of the Mortgage Loans, the Trust Subordinate Companion Loans and the portion of any REO Loans held by the Trust is less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage Loans (solely for the purposes of this calculation, if such right is being exercised after December 2027 and the 237 East Fordham Road Mortgage Loan is still an asset of the Trust, then such Mortgage Loan will be excluded from the then-aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate Companion Loans and from the aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate Companion Loans as of the Cut-off Date) as set forth in the Pooling and Servicing Agreement.

Following the date on which the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class A-S, Class X-A, Class X-B, Class X-E, Class B and Class C Regular Interests have been reduced to zero (and provided that there is only one Holder (or multiple Holders acting in unanimity) of the then-outstanding Certificates (other than the Class Z and Class R Certificates)), the Sole Certificateholder shall have the right, with the consent of the Master Servicer, to exchange all of its Certificates (other than the Class Z and Class R Certificates) together with the payment or deemed payment of the Termination Purchase Amount for all of the Mortgage Loans, the Trust Subordinate Companion Loans and each REO Property remaining in the Trust Fund pursuant to the terms of the Pooling and Servicing Agreement.

The obligations created by the Pooling and Servicing Agreement and the Trust created thereby (other than the obligation of the Certificate Administrator to make payments to

A-26-11 

Certificateholders as provided for in the Pooling and Servicing Agreement), shall terminate upon reduction of the Certificate Balances of all the Certificates to zero (including, without limitation, any such final payment resulting from a termination of the Trust due to a sale of its property) pursuant to the terms of the Pooling and Servicing Agreement. In no event, however, will the Trust created by the Pooling and Servicing Agreement continue beyond the expiration of 21 years from the death of the last survivor of the descendants of Joseph P. Kennedy, the late Ambassador of the United States to the Court of St. James, living on the date hereof.

Unless the certificate of authentication hereon has been executed by the Authenticating Agent, by manual signature, this Certificate shall not be entitled to any benefit under the Pooling and Servicing Agreement or be valid for any purpose. The Certificate Registrar has executed this Certificate on behalf of the Trust as Certificate Registrar under the Pooling and Servicing Agreement and makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates, the Mortgage Loans or the Trust Subordinate Companion Loans.

This Certificate is issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of November 1, 2017 (the “Pooling and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities Corp., as Depositor, Wells Fargo Bank, National Association, as Certificate Administrator and as Trustee, Park Bridge Lender Services LLC, as Operating Advisor and as Asset Representations Reviewer, KeyBank National Association, as Master Servicer, and CWCapital Asset Management LLC, as Special Servicer. To the extent not defined herein, capitalized terms used herein shall have the meanings assigned thereto in the Pooling and Servicing Agreement.

This Certificate represents beneficial ownership of a “regular interest” in a “real estate mortgage investment conduit,” as those terms are defined, respectively, in Sections 860G(a)(1) and 860D of the Internal Revenue Code of 1986, as amended.

The Certificate Administrator makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates, the Mortgage Loans or the Trust Subordinate Companion Loans and has executed this Certificate in its limited capacity as Certificate Administrator under the Pooling and Servicing Agreement.

Pursuant to the terms of the Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution on any Certificate), on the 4th Business Day following the determination date of each month, commencing in December 2017 (each such date, a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related Record Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this Certificate) of that portion of the aggregate amount of interest then distributable, if any, allocable to the Class STN-X Certificates for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement.

Interest accrued on this Certificate during an Interest Accrual Period, plus the aggregate unpaid Interest Shortfall with respect to this Certificate, if any, will be payable on the related Distribution Date to the extent provided in the Pooling and Servicing Agreement. The “Interest Accrual Period” with respect to any Distribution Date and with respect to the Class STN-X Certificates is the calendar month immediately preceding the month in which such Distribution Date occurs and is assumed to consist of 30 days.

All distributions (other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons in whose names the Certificates are registered at the close of business on each Record Date, which will be the close of business on the last Business Day of the month immediately preceding the month in which such Distribution Date occurs. Distributions are required to be made (a) by wire transfer of immediately available funds to the account of such Certificateholder at a bank or other entity having appropriate facilities

 A-26-4

therefor, if such Certificateholder provided the Certificate Administrator with written wiring instructions no less than five Business Days prior to the related Record Date (which wiring instructions may be in the form of a standing order applicable to all subsequent Distribution Dates), or otherwise (b) by check mailed to such Certificateholder at its address in the Certificate Register. The final distribution on each Certificate will be made in like manner, but only upon presentment and surrender of such Certificate at the offices of the Certificate Registrar or such other location specified in the notice to Certificateholders of such final distribution.

Any funds not distributed to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure of such Certificateholders to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited to the account or accounts of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been given pursuant to Section 4.01(l) of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within six months after the time specified in such notice, the Certificate Administrator shall mail a second notice to the remaining non tendering Certificateholders to surrender their Certificates for cancellation in order to receive the final distribution with respect thereto. If within one year after the second notice all such Certificates shall not have been surrendered for cancellation, the Certificate Administrator, directly or through an agent, shall take such steps to contact the remaining non tendering Certificateholders concerning the surrender of their Certificates as it shall deem appropriate and subject to escheatment and other applicable laws. The costs and expenses of holding such funds in trust and of contacting such Certificateholders following the first anniversary of the delivery of such second notice to the non-tendering Certificateholders shall be paid out of such funds. No interest shall accrue or be payable to any Certificateholder on any amount held in trust under the Pooling and Servicing Agreement by the Certificate Administrator as a result of such Certificateholder’s failure to surrender its Certificate(s) for final payment thereof in accordance with Section 4.01(l) of the Pooling and Servicing Agreement.

This Certificate is limited in right of payment to, among other things, certain collections and recoveries in respect of the Standard Highline Trust Subordinate Companion Loan, as more specifically set forth herein and in the Pooling and Servicing Agreement.

As provided in the Pooling and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject to the Pooling and Servicing Agreement (including any Qualified Substitute Mortgage Loan replacing a removed Mortgage Loan) and the Trust Subordinate Companion Loans, together with the Mortgage Files relating thereto (subject to, in the case of a Serviced Whole Loan, the interests of the related Serviced Companion Noteholder in the related Mortgage File); (ii) all scheduled or unscheduled payments on or collections in respect of the Mortgage Loans and the Trust Subordinate Companion Loans due after the Cut-off Date (or with respect to a Qualified Substitute Mortgage Loan, the Due Date in the month of substitution); (iii) any REO Property (to the extent of the Trust’s interest therein) or the Trust’s beneficial interest in the Mortgaged Property securing a Non Serviced Whole Loan acquired under the related Non-Serviced PSA; (iv) all revenues received in respect of any REO Property (to the extent of the Trust’s interest therein); (v) the Master Servicer’s, the Special Servicer’s, the Certificate Administrator’s and the Trustee’s rights under the insurance policies with respect to the Mortgage Loans and the Trust Subordinate Companion Loans required to be maintained pursuant to the Pooling and Servicing Agreement and any proceeds thereof (to the

 A-26-5

extent of the Trust’s interest therein); (vi) any Assignment of Leases and any security agreements (to the extent of the Trust’s interest therein); (vii) any letters of credit, indemnities, guaranties or lease enhancement policies given as additional security for any related Mortgage Loans or Trust Subordinate Companion Loans (to the extent of the Trust’s interest therein); (viii) all assets deposited in the Loss of Value Reserve Fund and the Servicing Accounts (to the extent of the Trust’s interest therein), amounts on deposit in the Collection Account (to the extent of the Trust’s interest therein), the Lower-Tier REMIC Distribution Account, the Upper-Tier REMIC Distribution Account, the Trust Subordinate Companion Loan REMIC Distribution Accounts, the Regular Interest Distribution Account, the Excess Interest Distribution Account, the Interest Reserve Account, the Gain-on-Sale Reserve Account (to the extent of the Trust’s interest therein) and any REO Account (to the extent of the Trust’s interest therein), including any reinvestment income, as applicable; (ix) any Environmental Indemnity Agreements (to the extent of the Trust’s interest therein); (x) the rights and remedies of the Depositor under each Mortgage Loan Purchase Agreement (to the extent transferred to the Trustee); (xi) the Lower-Tier Regular Interests; (xii) the Trust Subordinate Companion Loan REMIC Regular Interests; and (xiii) the proceeds of the foregoing (other than any interest earned on deposits in the lock-box accounts, cash collateral accounts, escrow accounts and any reserve accounts, to the extent such interest belongs to the related Mortgagor).

This Certificate does not purport to summarize the Pooling and Servicing Agreement, and reference is made to the Pooling and Servicing Agreement for the interests, rights, benefits, obligations and duties evidenced hereby, and the limitations thereon, and the rights, duties and immunities of the Certificate Administrator and Trustee.

As provided in the Pooling and Servicing Agreement, subject to certain restrictions on transfer set forth therein, upon surrender for registration of transfer of any Certificate, the Certificate Administrator shall execute, authenticate and deliver, in the name of the designated transferee or transferees, one or more new Certificates in authorized denominations, in like aggregate interest and of the same Class.

Prior to due presentation of this Certificate for registration of transfer, the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Certificate Registrar, and any agent of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate Registrar may treat the Person in whose name any Certificate is registered as the owner of such Certificate for the purpose of receiving distributions as provided in the Pooling and Servicing Agreement and for all other purposes whatsoever, and none of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Certificate Registrar, or any agent of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate Registrar shall be affected by any notice to the contrary.

(vi) to revise or add any other provisions with respect to matters or questions arising under the Pooling and Servicing Agreement or any other change; provided that the required action shall not adversely affect in any material respect the interests of any Certificateholder (including, for the avoidance of doubt, any Holder of a VRR Interest, a Y&L Towers VRR Interest or a Standard Highline VRR Interest) or any holder of a Serviced Pari Passu Companion Loan not consenting to such revision or addition, as evidenced in writing by an Opinion of Counsel, at the expense of the party requesting such amendment or as evidenced by a Rating Agency Confirmation from each of the Rating Agencies with respect to such amendment or supplement and confirmation of the applicable rating agencies that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings of any class of Serviced Companion Loan Securities, if any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement);

Notwithstanding the foregoing, no such amendment (A) may change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations of any

 A-26-9

Mortgage Loan Seller under any Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller or (B) may materially and adversely affect the holders of a Companion Loan without such Companion Holder’s consent.

The Pooling and Servicing Agreement may also be amended from time to time by the parties thereto with the consent of the Holders of Certificates of each Class affected by such amendment (including, for the avoidance of doubt, any Holders of the VRR Interest, the Y&L Towers VRR Interest or the Standard Highline VRR Interest to the extent any such amendment would adversely affect the rights of such Certificateholders) evidencing in the aggregate not less than a majority of the aggregate Percentage Interests constituting the Class for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of the Pooling and Servicing Agreement or of modifying in any manner the rights of the Holders of Certificates of such Class; provided, however, that no such amendment shall:

(i) reduce in any manner the amount of, or delay the timing of, payments received on the Mortgage Loans or the Trust Subordinate Companion Loans that are required to be distributed on a Certificate of any class without the consent of the Holder of the Certificate or which are required to be distributed to a Companion Holder without the consent of such Companion Holder; or

(ii) reduce the aforesaid percentage of Certificates of any Class the Holders of which are required to consent to any such amendment or remove the requirement to obtain consent of any Companion Holder or Holder of Loan-Specific Certificates, in any such case, without the consent of the Holders of all Certificates of such Class then-outstanding or such Companion Holders, as applicable; or

(v) amend the Servicing Standard without the consent of 100% of the Certificateholders or receipt of Rating Agency Confirmation from each Rating Agency and confirmation of the applicable rating agencies that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings of any Serviced Companion Loan Securities, if any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be

 A-26-10

considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement) and, if required under the related Intercreditor Agreement, the consent of the holder of any AB Subordinate Companion Loan for each Serviced AB Whole Loan.

Notwithstanding the foregoing, none of the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Depositor, the Master Servicer nor the Special Servicer will be required to consent to any amendment to the Pooling and Servicing Agreement without having first received an Opinion of Counsel (at the Trust’s expense) to the effect that such amendment is permitted under the Pooling and Servicing Agreement, that all conditions precedent have been satisfied and that such amendment or the exercise of any power granted to the Master Servicer, the Special Servicer, the Depositor, the Trustee, the Certificate Administrator, the Operating Advisor, the Asset Representations Reviewer or any other specified person in accordance with such amendment will not result in the imposition of a tax on any portion of the Trust Fund or any Trust REMIC, or cause any Trust REMIC to fail to qualify as a REMIC or cause the Grantor Trust to fail to qualify as a grantor trust under the relevant provisions of the Code.

The Holders of the majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates may, in that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the Certificate Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage Loans (and all property acquired through exercise of remedies in respect of any related Mortgage Loan), the Trust Subordinate Companion Loans and the Trust’s portion of each REO Property remaining in the Trust Fund, and thereby effect termination of the Trust and early retirement of the then-outstanding Certificates, only on or after the first Distribution Date on which the aggregate Stated Principal Balances of the Mortgage Loans, the Trust Subordinate Companion Loans and the portion of any REO Loans held by the Trust is less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage Loans (solely for the purposes of this calculation, if such right is being exercised after December 2027 and the 237 East Fordham Road Mortgage Loan is still an asset of the Trust, then such Mortgage Loan will be excluded from the then-aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate Companion Loans and from the aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate Companion Loans as of the Cut-off Date) as set forth in the Pooling and Servicing Agreement.

Following the date on which the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class A-S, Class X-A, Class X-B, Class X-E, Class B and Class C Regular Interests have been reduced to zero (and provided that there is only one Holder (or multiple Holders acting in unanimity) of the then-outstanding Certificates (other than the Class Z and Class R Certificates)), the Sole Certificateholder shall have the right, with the consent of the Master Servicer, to exchange all of its Certificates (other than the Class Z and Class R Certificates) together with the payment or deemed payment of the Termination Purchase Amount for all of the Mortgage Loans, the Trust Subordinate Companion Loans and each REO Property remaining in the Trust Fund pursuant to the terms of the Pooling and Servicing Agreement.

The obligations created by the Pooling and Servicing Agreement and the Trust created thereby (other than the obligation of the Certificate Administrator to make payments to

 A-26-11

Certificateholders as provided for in the Pooling and Servicing Agreement), shall terminate upon reduction of the Certificate Balances of all the Certificates to zero (including, without limitation, any such final payment resulting from a termination of the Trust due to a sale of its property) pursuant to the terms of the Pooling and Servicing Agreement. In no event, however, will the Trust created by the Pooling and Servicing Agreement continue beyond the expiration of 21 years from the death of the last survivor of the descendants of Joseph P. Kennedy, the late Ambassador of the United States to the Court of St. James, living on the date hereof.

Unless the certificate of authentication hereon has been executed by the Authenticating Agent, by manual signature, this Certificate shall not be entitled to any benefit under the Pooling and Servicing Agreement or be valid for any purpose. The Certificate Registrar has executed this Certificate on behalf of the Trust as Certificate Registrar under the Pooling and Servicing Agreement and makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates, the Mortgage Loans or the Trust Subordinate Companion Loans.

This Certificate is issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of November 1, 2017 (the “Pooling and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities Corp., as Depositor, Wells Fargo Bank, National Association, as Certificate Administrator and as Trustee, Park Bridge Lender Services LLC, as Operating Advisor and as Asset Representations Reviewer, KeyBank National Association, as Master Servicer, and CWCapital Asset Management LLC, as Special Servicer. To the extent not defined herein, capitalized terms used herein shall have the meanings assigned thereto in the Pooling and Servicing Agreement.

This Certificate represents beneficial ownership of a “regular interest” in a “real estate mortgage investment conduit,” as those terms are defined, respectively, in Sections 860G(a)(1) and 860D of the Internal Revenue Code of 1986, as amended.

The Certificate Administrator makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates, the Mortgage Loans or the Trust Subordinate Companion Loans and has executed this Certificate in its limited capacity as Certificate Administrator under the Pooling and Servicing Agreement.

Pursuant to the terms of the Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution on any Certificate), on the 4th Business Day following the determination date of each month, commencing in December 2017 (each such date, a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related Record Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this Certificate) of that portion of the aggregate amount of principal and interest then distributable, if any, allocable to the Class STN-C Certificates for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement.

Interest accrued on this Certificate during an Interest Accrual Period, plus the aggregate unpaid Interest Shortfall with respect to this Certificate, if any, will be payable on the related Distribution Date to the extent provided in the Pooling and Servicing Agreement. The “Interest Accrual Period” with respect to any Distribution Date and with respect to the Class STN-C Certificates is the calendar month immediately preceding the month in which such Distribution Date occurs and is assumed to consist of 30 days.

All distributions (other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons in whose names the Certificates are registered at the close of business on each Record Date, which will be the close of business on the last Business Day of the month immediately preceding the month in which such Distribution Date occurs. Distributions are required to be made (a) by wire transfer of immediately available funds to the account of such Certificateholder at a bank or other entity having appropriate facilities therefor, if such Certificateholder provided the Certificate Administrator with written wiring

A-26-4

instructions no less than five Business Days prior to the related Record Date (which wiring instructions may be in the form of a standing order applicable to all subsequent Distribution Dates), or otherwise (b) by check mailed to such Certificateholder at its address in the Certificate Register. The final distribution on each Certificate will be made in like manner, but only upon presentment and surrender of such Certificate at the offices of the Certificate Registrar or such other location specified in the notice to Certificateholders of such final distribution.

Any funds not distributed to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure of such Certificateholders to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited to the account or accounts of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been given pursuant to Section 4.01(l) of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within six months after the time specified in such notice, the Certificate Administrator shall mail a second notice to the remaining non tendering Certificateholders to surrender their Certificates for cancellation in order to receive the final distribution with respect thereto. If within one year after the second notice all such Certificates shall not have been surrendered for cancellation, the Certificate Administrator, directly or through an agent, shall take such steps to contact the remaining non tendering Certificateholders concerning the surrender of their Certificates as it shall deem appropriate and subject to escheatment and other applicable laws. The costs and expenses of holding such funds in trust and of contacting such Certificateholders following the first anniversary of the delivery of such second notice to the non-tendering Certificateholders shall be paid out of such funds. No interest shall accrue or be payable to any Certificateholder on any amount held in trust under the Pooling and Servicing Agreement by the Certificate Administrator as a result of such Certificateholder’s failure to surrender its Certificate(s) for final payment thereof in accordance with Section 4.01(l) of the Pooling and Servicing Agreement.

This Certificate is limited in right of payment to, among other things, certain collections and recoveries in respect of theStandard Highline Trust Subordinate Companion Loan, as more specifically set forth herein and in the Pooling and Servicing Agreement.

As provided in the Pooling and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject to the Pooling and Servicing Agreement (including any Qualified Substitute Mortgage Loan replacing a removed Mortgage Loan) and the Trust Subordinate Companion Loans, together with the Mortgage Files relating thereto (subject to, in the case of a Serviced Whole Loan, the interests of the related Serviced Companion Noteholder in the related Mortgage File); (ii) all scheduled or unscheduled payments on or collections in respect of the Mortgage Loans and the Trust Subordinate Companion Loans due after the Cut-off Date (or with respect to a Qualified Substitute Mortgage Loan, the Due Date in the month of substitution); (iii) any REO Property (to the extent of the Trust’s interest therein) or the Trust’s beneficial interest in the Mortgaged Property securing a Non Serviced Whole Loan acquired under the related Non-Serviced PSA; (iv) all revenues received in respect of any REO Property (to the extent of the Trust’s interest therein); (v) the Master Servicer’s, the Special Servicer’s, the Certificate Administrator’s and the Trustee’s rights under the insurance policies with respect to the Mortgage Loans and the Trust Subordinate Companion Loans required to be maintained pursuant to the Pooling and Servicing Agreement and any proceeds thereof (to the extent of the Trust’s interest therein); (vi) any Assignment of Leases and any security agreements

A-26-5

(to the extent of the Trust’s interest therein); (vii) any letters of credit, indemnities, guaranties or lease enhancement policies given as additional security for any related Mortgage Loans or Trust Subordinate Companion Loans (to the extent of the Trust’s interest therein); (viii) all assets deposited in the Loss of Value Reserve Fund and the Servicing Accounts (to the extent of the Trust’s interest therein), amounts on deposit in the Collection Account (to the extent of the Trust’s interest therein), the Lower-Tier REMIC Distribution Account, the Upper-Tier REMIC Distribution Account, the Trust Subordinate Companion Loan REMIC Distribution Accounts, the Regular Interest Distribution Account, the Excess Interest Distribution Account, the Interest Reserve Account, the Gain-on-Sale Reserve Account (to the extent of the Trust’s interest therein) and any REO Account (to the extent of the Trust’s interest therein), including any reinvestment income, as applicable; (ix) any Environmental Indemnity Agreements (to the extent of the Trust’s interest therein); (x) the rights and remedies of the Depositor under each Mortgage Loan Purchase Agreement (to the extent transferred to the Trustee); (xi) the Lower-Tier Regular Interests; (xii) the Trust Subordinate Companion Loan REMIC Regular Interests; and (xiii) the proceeds of the foregoing (other than any interest earned on deposits in the lock-box accounts, cash collateral accounts, escrow accounts and any reserve accounts, to the extent such interest belongs to the related Mortgagor).

This Certificate does not purport to summarize the Pooling and Servicing Agreement, and reference is made to the Pooling and Servicing Agreement for the interests, rights, benefits, obligations and duties evidenced hereby, and the limitations thereon, and the rights, duties and immunities of the Certificate Administrator and Trustee.

As provided in the Pooling and Servicing Agreement, subject to certain restrictions on transfer set forth therein, upon surrender for registration of transfer of any Certificate, the Certificate Administrator shall execute, authenticate and deliver, in the name of the designated transferee or transferees, one or more new Certificates in authorized denominations, in like aggregate interest and of the same Class.

Prior to due presentation of this Certificate for registration of transfer, the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Certificate Registrar, and any agent of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate Registrar may treat the Person in whose name any Certificate is registered as the owner of such Certificate for the purpose of receiving distributions as provided in the Pooling and Servicing Agreement and for all other purposes whatsoever, and none of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Certificate Registrar, or any agent of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate Registrar shall be affected by any notice to the contrary.

(vi) to revise or add any other provisions with respect to matters or questions arising under the Pooling and Servicing Agreement or any other change; provided that the required action shall not adversely affect in any material respect the interests of any Certificateholder (including, for the avoidance of doubt, any Holder of a VRR Interest, a Y&L Towers VRR Interest or a Standard Highline VRR Interest) or any holder of a Serviced Pari Passu Companion Loan not consenting to such revision or addition, as evidenced in writing by an Opinion of Counsel, at the expense of the party requesting such amendment or as evidenced by a Rating Agency Confirmation from each of the Rating Agencies with respect to such amendment or supplement and confirmation of the applicable rating agencies that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings of any class of Serviced Companion Loan Securities, if any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement);

Notwithstanding the foregoing, no such amendment (A) may change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations of any

A-26-9

Mortgage Loan Seller under any Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller or (B) may materially and adversely affect the holders of a Companion Loan without such Companion Holder’s consent.

The Pooling and Servicing Agreement may also be amended from time to time by the parties thereto with the consent of the Holders of Certificates of each Class affected by such amendment (including, for the avoidance of doubt, any Holders of the VRR Interest, the Y&L Towers VRR Interest or the Standard Highline VRR Interest to the extent any such amendment would adversely affect the rights of such Certificateholders) evidencing in the aggregate not less than a majority of the aggregate Percentage Interests constituting the Class for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of the Pooling and Servicing Agreement or of modifying in any manner the rights of the Holders of Certificates of such Class; provided, however, that no such amendment shall:

(i) reduce in any manner the amount of, or delay the timing of, payments received on the Mortgage Loans or the Trust Subordinate Companion Loans that are required to be distributed on a Certificate of any class without the consent of the Holder of the Certificate or which are required to be distributed to a Companion Holder without the consent of such Companion Holder; or

(ii) reduce the aforesaid percentage of Certificates of any Class the Holders of which are required to consent to any such amendment or remove the requirement to obtain consent of any Companion Holder or Holder of Loan-Specific Certificates, in any such case, without the consent of the Holders of all Certificates of such Class then-outstanding or such Companion Holders, as applicable; or

(iii) adversely affect the Voting Rights of any Class of Certificates without the consent of the Holders of all Certificates of such Class then outstanding; or

(iv) change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations of any Mortgage Loan Seller under such Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller; or

(v) amend the Servicing Standard without the consent of 100% of the Certificateholders or receipt of Rating Agency Confirmation from each Rating Agency and confirmation of the applicable rating agencies that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings of any Serviced Companion Loan Securities, if any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be

A-26-10

considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement) and, if required under the related Intercreditor Agreement, the consent of the holder of any AB Subordinate Companion Loan for each Serviced AB Whole Loan.

Notwithstanding the foregoing, none of the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Depositor, the Master Servicer nor the Special Servicer will be required to consent to any amendment to the Pooling and Servicing Agreement without having first received an Opinion of Counsel (at the Trust’s expense) to the effect that such amendment is permitted under the Pooling and Servicing Agreement, that all conditions precedent have been satisfied and that such amendment or the exercise of any power granted to the Master Servicer, the Special Servicer, the Depositor, the Trustee, the Certificate Administrator, the Operating Advisor, the Asset Representations Reviewer or any other specified person in accordance with such amendment will not result in the imposition of a tax on any portion of the Trust Fund or any Trust REMIC, or cause any Trust REMIC to fail to qualify as a REMIC or cause the Grantor Trust to fail to qualify as a grantor trust under the relevant provisions of the Code.

The Holders of the majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates may, in that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the Certificate Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage Loans (and all property acquired through exercise of remedies in respect of any related Mortgage Loan), the Trust Subordinate Companion Loans and the Trust’s portion of each REO Property remaining in the Trust Fund, and thereby effect termination of the Trust and early retirement of the then-outstanding Certificates, only on or after the first Distribution Date on which the aggregate Stated Principal Balances of the Mortgage Loans, the Trust Subordinate Companion Loans and the portion of any REO Loans held by the Trust is less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage Loans (solely for the purposes of this calculation, if such right is being exercised after December 2027 and the 237 East Fordham Road Mortgage Loan is still an asset of the Trust, then such Mortgage Loan will be excluded from the then-aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate Companion Loans and from the aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate Companion Loans as of the Cut-off Date) as set forth in the Pooling and Servicing Agreement.

Following the date on which the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class A-S, Class X-A, Class X-B, Class X-E, Class B and Class C Regular Interests have been reduced to zero (and provided that there is only one Holder (or multiple Holders acting in unanimity) of the then-outstanding Certificates (other than the Class Z and Class R Certificates)), the Sole Certificateholder shall have the right, with the consent of the Master Servicer, to exchange all of its Certificates (other than the Class Z and Class R Certificates) together with the payment or deemed payment of the Termination Purchase Amount for all of the Mortgage Loans, the Trust Subordinate Companion Loans and each REO Property remaining in the Trust Fund pursuant to the terms of the Pooling and Servicing Agreement.

The obligations created by the Pooling and Servicing Agreement and the Trust created thereby (other than the obligation of the Certificate Administrator to make payments to

A-26-11

Certificateholders as provided for in the Pooling and Servicing Agreement), shall terminate upon reduction of the Certificate Balances of all the Certificates to zero (including, without limitation, any such final payment resulting from a termination of the Trust due to a sale of its property) pursuant to the terms of the Pooling and Servicing Agreement. In no event, however, will the Trust created by the Pooling and Servicing Agreement continue beyond the expiration of 21 years from the death of the last survivor of the descendants of Joseph P. Kennedy, the late Ambassador of the United States to the Court of St. James, living on the date hereof.

Unless the certificate of authentication hereon has been executed by the Authenticating Agent, by manual signature, this Certificate shall not be entitled to any benefit under the Pooling and Servicing Agreement or be valid for any purpose. The Certificate Registrar has executed this Certificate on behalf of the Trust as Certificate Registrar under the Pooling and Servicing Agreement and makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates, the Mortgage Loans or the Trust Subordinate Companion Loans.

This Certificate is issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of November 1, 2017 (the “Pooling and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities Corp., as Depositor, Wells Fargo Bank, National Association, as Certificate Administrator and as Trustee, Park Bridge Lender Services LLC, as Operating Advisor and as Asset Representations Reviewer, KeyBank National Association, as Master Servicer, and CWCapital Asset Management LLC, as Special Servicer. To the extent not defined herein, capitalized terms used herein shall have the meanings assigned thereto in the Pooling and Servicing Agreement.

This Certificate represents beneficial ownership of multiple “regular interests” in a “real estate mortgage investment conduit,” as those terms are defined, respectively, in Sections 860G(a)(1) and 860D of the Internal Revenue Code of 1986, as amended.

The Certificate Administrator makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates, the Mortgage Loans or the Trust Subordinate Companion Loans and has executed this Certificate in its limited capacity as Certificate Administrator under the Pooling and Servicing Agreement.

Pursuant to the terms of the Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution on any Certificate), on the 4th Business Day following the determination date of each month, commencing in December 2017 (each such date, a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related Record Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this Certificate) of that portion of the aggregate amount of principal and interest then distributable, if any, allocable to the Class V1-UESA Certificates for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement.

Interest accrued on this Certificate during an Interest Accrual Period, plus the aggregate unpaid Interest Shortfall with respect to this Certificate, if any, will be payable on the related Distribution Date to the extent provided in the Pooling and Servicing Agreement. The “Interest Accrual Period” with respect to any Distribution Date and with respect to the Class V1-UESA Certificates is the calendar month immediately preceding the month in which such Distribution Date occurs and is assumed to consist of 30 days.

All distributions (other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons in whose names the Certificates are registered at the close of business on each Record Date, which will be the close of business on the last Business Day of the month immediately preceding the month in which such Distribution Date occurs. Distributions are required to be made (a) by wire transfer of immediately available funds to the account of such Certificateholder at a bank or other entity having appropriate facilities therefor,

A-26-4

if such Certificateholder provided the Certificate Administrator with written wiring instructions no less than five Business Days prior to the related Record Date (which wiring instructions may be in the form of a standing order applicable to all subsequent Distribution Dates), or otherwise (b) by check mailed to such Certificateholder at its address in the Certificate Register. The final distribution on each Certificate will be made in like manner, but only upon presentment and surrender of such Certificate at the offices of the Certificate Registrar or such other location specified in the notice to Certificateholders of such final distribution.

Any funds not distributed to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure of such Certificateholders to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited to the account or accounts of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been given pursuant to Section 4.01(l) of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within six months after the time specified in such notice, the Certificate Administrator shall mail a second notice to the remaining non tendering Certificateholders to surrender their Certificates for cancellation in order to receive the final distribution with respect thereto. If within one year after the second notice all such Certificates shall not have been surrendered for cancellation, the Certificate Administrator, directly or through an agent, shall take such steps to contact the remaining non tendering Certificateholders concerning the surrender of their Certificates as it shall deem appropriate and subject to escheatment and other applicable laws. The costs and expenses of holding such funds in trust and of contacting such Certificateholders following the first anniversary of the delivery of such second notice to the non-tendering Certificateholders shall be paid out of such funds. No interest shall accrue or be payable to any Certificateholder on any amount held in trust under the Pooling and Servicing Agreement by the Certificate Administrator as a result of such Certificateholder’s failure to surrender its Certificate(s) for final payment thereof in accordance with Section 4.01(l) of the Pooling and Servicing Agreement.

This Certificate is limited in right of payment to, among other things, certain collections and recoveries in respect of the Y&L Towers Trust Subordinate Companion Loan, as more specifically set forth herein and in the Pooling and Servicing Agreement.

As provided in the Pooling and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject to the Pooling and Servicing Agreement (including any Qualified Substitute Mortgage Loan replacing a removed Mortgage Loan) and the Trust Subordinate Companion Loans, together with the Mortgage Files relating thereto (subject to, in the case of a Serviced Whole Loan, the interests of the related Serviced Companion Noteholder in the related Mortgage File); (ii) all scheduled or unscheduled payments on or collections in respect of the Mortgage Loans and the Trust Subordinate Companion Loans due after the Cut-off Date (or with respect to a Qualified Substitute Mortgage Loan, the Due Date in the month of substitution); (iii) any REO Property (to the extent of the Trust’s interest therein) or the Trust’s beneficial interest in the Mortgaged Property securing a Non Serviced Whole Loan acquired under the related Non-Serviced PSA; (iv) all revenues received in respect of any REO Property (to the extent of the Trust’s interest therein); (v) the Master Servicer’s, the Special Servicer’s, the Certificate Administrator’s and the Trustee’s rights under the insurance policies with respect to the Mortgage Loans and the Trust Subordinate Companion Loans required to be maintained pursuant to the Pooling and Servicing Agreement and any proceeds thereof (to the

A-26-5

extent of the Trust’s interest therein); (vi) any Assignment of Leases and any security agreements (to the extent of the Trust’s interest therein); (vii) any letters of credit, indemnities, guaranties or lease enhancement policies given as additional security for any related Mortgage Loans or Trust Subordinate Companion Loans (to the extent of the Trust’s interest therein); (viii) all assets deposited in the Loss of Value Reserve Fund and the Servicing Accounts (to the extent of the Trust’s interest therein), amounts on deposit in the Collection Account (to the extent of the Trust’s interest therein), the Lower-Tier REMIC Distribution Account, the Upper-Tier REMIC Distribution Account, the Trust Subordinate Companion Loan REMIC Distribution Accounts, the Regular Interest Distribution Account, the Excess Interest Distribution Account, the Interest Reserve Account, the Gain-on-Sale Reserve Account (to the extent of the Trust’s interest therein) and any REO Account (to the extent of the Trust’s interest therein), including any reinvestment income, as applicable; (ix) any Environmental Indemnity Agreements (to the extent of the Trust’s interest therein); (x) the rights and remedies of the Depositor under each Mortgage Loan Purchase Agreement (to the extent transferred to the Trustee); (xi) the Lower-Tier Regular Interests; (xii) the Trust Subordinate Companion Loan REMIC Regular Interests; and (xiii) the proceeds of the foregoing (other than any interest earned on deposits in the lock-box accounts, cash collateral accounts, escrow accounts and any reserve accounts, to the extent such interest belongs to the related Mortgagor).

This Certificate does not purport to summarize the Pooling and Servicing Agreement, and reference is made to the Pooling and Servicing Agreement for the interests, rights, benefits, obligations and duties evidenced hereby, and the limitations thereon, and the rights, duties and immunities of the Certificate Administrator and Trustee.

As provided in the Pooling and Servicing Agreement, subject to certain restrictions on transfer set forth therein, upon surrender for registration of transfer of any Certificate, the Certificate Administrator shall execute, authenticate and deliver, in the name of the designated transferee or transferees, one or more new Certificates in authorized denominations, in like aggregate interest and of the same Class.

Prior to due presentation of this Certificate for registration of transfer, the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Certificate Registrar, and any agent of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate Registrar may treat the Person in whose name any Certificate is registered as the owner of such Certificate for the purpose of receiving distributions as provided in the Pooling and Servicing Agreement and for all other purposes whatsoever, and none of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Certificate Registrar, or any agent of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate Registrar shall be affected by any notice to the contrary.

A-26-7

(vi) to revise or add any other provisions with respect to matters or questions arising under the Pooling and Servicing Agreement or any other change; provided that the required action shall not adversely affect in any material respect the interests of any Certificateholder (including, for the avoidance of doubt, any Holder of a VRR Interest, a Y&L Towers VRR Interest or a Standard Highline VRR Interest) or any holder of a Serviced Pari Passu Companion Loan not consenting to such revision or addition, as evidenced in writing by an Opinion of Counsel, at the expense of the party requesting such amendment or as evidenced by a Rating Agency Confirmation from each of the Rating Agencies with respect to such amendment or supplement and confirmation of the applicable rating agencies that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings of any class of Serviced Companion Loan Securities, if any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement);

(viii) to modify the provisions of Sections 3.05 and 3.17 of the Pooling and Servicing Agreement (with respect to reimbursement of Nonrecoverable Advances and Workout-Delayed Reimbursement Amounts) if (a) the Depositor, the Master Servicer, the Trustee and, for so long as a Control Termination Event has not occurred and is not continuing and, with respect to any Mortgage Loans other than any Excluded Loan, as to the Directing Holder or, in the case of the Directing Certificateholder, the Holder of a majority of the Controlling Class, the Directing Holder, determine that the commercial mortgage backed securities industry standard for such provisions has changed, in order to conform to such industry standard, (b) such modification does not adversely affect the status of any Trust REMIC as a REMIC or the status of the Grantor Trust

A-26-8

as a grantor trust under the relevant provisions of the Code, as evidenced by an Opinion of Counsel and (c) each Rating Agency has delivered a Rating Agency Confirmation and, with regard to any class of Serviced Companion Loan Securities, the applicable rating agencies have delivered a confirmation that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement);

(ix) to modify the procedures of the Pooling and Servicing Agreement relating to compliance with Rule 17g-5 of the Exchange Act; provided that such amendment shall not adversely affect in any material respects the interests of any Certificateholders (including, for the avoidance of doubt, any Holders of a VRR Interest, a Y&L Towers VRR Interest or a Standard Highline VRR Interest), as evidenced by (x) an Opinion of Counsel or (y) if any Certificate is then rated, receipt of Rating Agency Confirmation from each Rating Agency rating such Certificates; and provided, further, that the Certificate Administrator shall give notice of any such amendment to the 17g-5 Information Provider for posting to the 17g-5 Information Provider’s Website pursuant to Section 3.13(c) of the Pooling and Servicing Agreement and the Certificate Administrator shall post such notice to the Certificate Administrator’s Website;

Notwithstanding the foregoing, no such amendment (A) may change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations of any Mortgage Loan Seller under any Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller or (B) may materially and adversely affect the holders of a Companion Loan without such Companion Holder’s consent.

The Pooling and Servicing Agreement may also be amended from time to time by the parties thereto with the consent of the Holders of Certificates of each Class affected by such amendment (including, for the avoidance of doubt, any Holders of the VRR Interest, the Y&L Towers VRR

A-26-9

Interest or the Standard Highline VRR Interest to the extent any such amendment would adversely affect the rights of such Certificateholders) evidencing in the aggregate not less than a majority of the aggregate Percentage Interests constituting the Class for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of the Pooling and Servicing Agreement or of modifying in any manner the rights of the Holders of Certificates of such Class; provided, however, that no such amendment shall:

(i) reduce in any manner the amount of, or delay the timing of, payments received on the Mortgage Loans or the Trust Subordinate Companion Loans that are required to be distributed on a Certificate of any class without the consent of the Holder of the Certificate or which are required to be distributed to a Companion Holder without the consent of such Companion Holder; or

(ii) reduce the aforesaid percentage of Certificates of any Class the Holders of which are required to consent to any such amendment or remove the requirement to obtain consent of any Companion Holder or Holder of Loan-Specific Certificates, in any such case, without the consent of the Holders of all Certificates of such Class then-outstanding or such Companion Holders, as applicable; or

(iii) adversely affect the Voting Rights of any Class of Certificates without the consent of the Holders of all Certificates of such Class then outstanding; or

(iv) change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations of any Mortgage Loan Seller under such Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller; or

(v) amend the Servicing Standard without the consent of 100% of the Certificateholders or receipt of Rating Agency Confirmation from each Rating Agency and confirmation of the applicable rating agencies that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings of any Serviced Companion Loan Securities, if any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement) and, if required under the related Intercreditor Agreement, the consent of the holder of any AB Subordinate Companion Loan for each Serviced AB Whole Loan.

Notwithstanding the foregoing, none of the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Depositor, the Master Servicer nor the Special Servicer will be required to consent to any amendment to the Pooling and Servicing Agreement without having first received an Opinion of Counsel (at the Trust’s expense) to the

A-26-10

effect that such amendment is permitted under the Pooling and Servicing Agreement, that all conditions precedent have been satisfied and that such amendment or the exercise of any power granted to the Master Servicer, the Special Servicer, the Depositor, the Trustee, the Certificate Administrator, the Operating Advisor, the Asset Representations Reviewer or any other specified person in accordance with such amendment will not result in the imposition of a tax on any portion of the Trust Fund or any Trust REMIC, or cause any Trust REMIC to fail to qualify as a REMIC or cause the Grantor Trust to fail to qualify as a grantor trust under the relevant provisions of the Code.

The Holders of the majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates may, in that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the Certificate Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage Loans (and all property acquired through exercise of remedies in respect of any related Mortgage Loan), the Trust Subordinate Companion Loans and the Trust’s portion of each REO Property remaining in the Trust Fund, and thereby effect termination of the Trust and early retirement of the then-outstanding Certificates, only on or after the first Distribution Date on which the aggregate Stated Principal Balances of the Mortgage Loans, the Trust Subordinate Companion Loans and the portion of any REO Loans held by the Trust is less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage Loans (solely for the purposes of this calculation, if such right is being exercised after December 2027 and the 237 East Fordham Road Mortgage Loan is still an asset of the Trust, then such Mortgage Loan will be excluded from the then-aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate Companion Loans and from the aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate Companion Loans as of the Cut-off Date) as set forth in the Pooling and Servicing Agreement.

Following the date on which the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class A-S, Class X-A, Class X-B, Class X-E, Class B and Class C Regular Interests have been reduced to zero (and provided that there is only one Holder (or multiple Holders acting in unanimity) of the then-outstanding Certificates (other than the Class Z and Class R Certificates)), the Sole Certificateholder shall have the right, with the consent of the Master Servicer, to exchange all of its Certificates (other than the Class Z and Class R Certificates) together with the payment or deemed payment of the Termination Purchase Amount for all of the Mortgage Loans, the Trust Subordinate Companion Loans and each REO Property remaining in the Trust Fund pursuant to the terms of the Pooling and Servicing Agreement.

The obligations created by the Pooling and Servicing Agreement and the Trust created thereby (other than the obligation of the Certificate Administrator to make payments to Certificateholders as provided for in the Pooling and Servicing Agreement), shall terminate upon reduction of the Certificate Balances of all the Certificates to zero (including, without limitation, any such final payment resulting from a termination of the Trust due to a sale of its property) pursuant to the terms of the Pooling and Servicing Agreement. In no event, however, will the Trust created by the Pooling and Servicing Agreement continue beyond the expiration of 21 years from the death of the last survivor of the descendants of Joseph P. Kennedy, the late Ambassador of the United States to the Court of St. James, living on the date hereof.

This Certificate is issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of November 1, 2017 (the “Pooling and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities Corp., as Depositor, Wells Fargo Bank, National Association, as Certificate Administrator and as Trustee, Park Bridge Lender Services LLC, as Operating Advisor and as Asset Representations Reviewer, KeyBank National Association, as Master Servicer, and CWCapital Asset Management LLC, as Special Servicer. To the extent not defined herein, capitalized terms used herein shall have the meanings assigned thereto in the Pooling and Servicing Agreement.

This Certificate represents beneficial ownership of a “regular interest” in a “real estate mortgage investment conduit,” as those terms are defined, respectively, in Sections 860G(a)(1) and 860D of the Internal Revenue Code of 1986, as amended.

The Certificate Administrator makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates, the Mortgage Loans or the Trust Subordinate Companion Loans and has executed this Certificate in its limited capacity as Certificate Administrator under the Pooling and Servicing Agreement.

Pursuant to the terms of the Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution on any Certificate), on the 4th Business Day following the determination date of each month, commencing in December 2017 (each such date, a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related Record Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this Certificate) of that portion of the aggregate amount of principal and interest then distributable, if any, allocable to the Class V1-UESD Certificates for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement.

Interest accrued on this Certificate during an Interest Accrual Period, plus the aggregate unpaid Interest Shortfall with respect to this Certificate, if any, will be payable on the related Distribution Date to the extent provided in the Pooling and Servicing Agreement. The “Interest Accrual Period” with respect to any Distribution Date and with respect to the Class V1-UESD Certificates is the calendar month immediately preceding the month in which such Distribution Date occurs and is assumed to consist of 30 days.

All distributions (other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons in whose names the Certificates are registered at the close of business on each Record Date, which will be the close of business on the last Business Day of the month immediately preceding the month in which such Distribution Date occurs. Distributions are required to be made (a) by wire transfer of immediately available funds to the account of such Certificateholder at a bank or other entity having appropriate facilities therefor,

A-26-5

if such Certificateholder provided the Certificate Administrator with written wiring instructions no less than five Business Days prior to the related Record Date (which wiring instructions may be in the form of a standing order applicable to all subsequent Distribution Dates), or otherwise (b) by check mailed to such Certificateholder at its address in the Certificate Register. The final distribution on each Certificate will be made in like manner, but only upon presentment and surrender of such Certificate at the offices of the Certificate Registrar or such other location specified in the notice to Certificateholders of such final distribution.

Any funds not distributed to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure of such Certificateholders to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited to the account or accounts of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been given pursuant to Section 4.01(l) of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within six months after the time specified in such notice, the Certificate Administrator shall mail a second notice to the remaining non tendering Certificateholders to surrender their Certificates for cancellation in order to receive the final distribution with respect thereto. If within one year after the second notice all such Certificates shall not have been surrendered for cancellation, the Certificate Administrator, directly or through an agent, shall take such steps to contact the remaining non tendering Certificateholders concerning the surrender of their Certificates as it shall deem appropriate and subject to escheatment and other applicable laws. The costs and expenses of holding such funds in trust and of contacting such Certificateholders following the first anniversary of the delivery of such second notice to the non-tendering Certificateholders shall be paid out of such funds. No interest shall accrue or be payable to any Certificateholder on any amount held in trust under the Pooling and Servicing Agreement by the Certificate Administrator as a result of such Certificateholder’s failure to surrender its Certificate(s) for final payment thereof in accordance with Section 4.01(l) of the Pooling and Servicing Agreement.

This Certificate is limited in right of payment to, among other things, certain collections and recoveries in respect of the Y&L Towers Trust Subordinate Companion Loan, as more specifically set forth herein and in the Pooling and Servicing Agreement.

As provided in the Pooling and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject to the Pooling and Servicing Agreement (including any Qualified Substitute Mortgage Loan replacing a removed Mortgage Loan) and the Trust Subordinate Companion Loans, together with the Mortgage Files relating thereto (subject to, in the case of a Serviced Whole Loan, the interests of the related Serviced Companion Noteholder in the related Mortgage File); (ii) all scheduled or unscheduled payments on or collections in respect of the Mortgage Loans and the Trust Subordinate Companion Loans due after the Cut-off Date (or with respect to a Qualified Substitute Mortgage Loan, the Due Date in the month of substitution); (iii) any REO Property (to the extent of the Trust’s interest therein) or the Trust’s beneficial interest in the Mortgaged Property securing a Non Serviced Whole Loan acquired under the related Non-Serviced PSA; (iv) all revenues received in respect of any REO Property (to the extent of the Trust’s interest therein); (v) the Master Servicer’s, the Special Servicer’s, the Certificate Administrator’s and the Trustee’s rights under the insurance policies with respect to the Mortgage Loans and the Trust Subordinate Companion Loans required to be maintained pursuant to the Pooling and Servicing Agreement and any proceeds thereof (to the

A-26-6

extent of the Trust’s interest therein); (vi) any Assignment of Leases and any security agreements (to the extent of the Trust’s interest therein); (vii) any letters of credit, indemnities, guaranties or lease enhancement policies given as additional security for any related Mortgage Loans or Trust Subordinate Companion Loans (to the extent of the Trust’s interest therein); (viii) all assets deposited in the Loss of Value Reserve Fund and the Servicing Accounts (to the extent of the Trust’s interest therein), amounts on deposit in the Collection Account (to the extent of the Trust’s interest therein), the Lower-Tier REMIC Distribution Account, the Upper-Tier REMIC Distribution Account, the Trust Subordinate Companion Loan REMIC Distribution Accounts, the Regular Interest Distribution Account, the Excess Interest Distribution Account, the Interest Reserve Account, the Gain-on-Sale Reserve Account (to the extent of the Trust’s interest therein) and any REO Account (to the extent of the Trust’s interest therein), including any reinvestment income, as applicable; (ix) any Environmental Indemnity Agreements (to the extent of the Trust’s interest therein); (x) the rights and remedies of the Depositor under each Mortgage Loan Purchase Agreement (to the extent transferred to the Trustee); (xi) the Lower-Tier Regular Interests; (xii) the Trust Subordinate Companion Loan REMIC Regular Interests; and (xiii) the proceeds of the foregoing (other than any interest earned on deposits in the lock-box accounts, cash collateral accounts, escrow accounts and any reserve accounts, to the extent such interest belongs to the related Mortgagor).

This Certificate does not purport to summarize the Pooling and Servicing Agreement, and reference is made to the Pooling and Servicing Agreement for the interests, rights, benefits, obligations and duties evidenced hereby, and the limitations thereon, and the rights, duties and immunities of the Certificate Administrator and Trustee.

As provided in the Pooling and Servicing Agreement, subject to certain restrictions on transfer set forth therein, upon surrender for registration of transfer of any Certificate, the Certificate Administrator shall execute, authenticate and deliver, in the name of the designated transferee or transferees, one or more new Certificates in authorized denominations, in like aggregate interest and of the same Class.

Prior to due presentation of this Certificate for registration of transfer, the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Certificate Registrar, and any agent of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate Registrar may treat the Person in whose name any Certificate is registered as the owner of such Certificate for the purpose of receiving distributions as provided in the Pooling and Servicing Agreement and for all other purposes whatsoever, and none of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Certificate Registrar, or any agent of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate Registrar shall be affected by any notice to the contrary.

A-26-8

(vi) to revise or add any other provisions with respect to matters or questions arising under the Pooling and Servicing Agreement or any other change; provided that the required action shall not adversely affect in any material respect the interests of any Certificateholder (including, for the avoidance of doubt, any Holder of a VRR Interest, a Y&L Towers VRR Interest or a Standard Highline VRR Interest) or any holder of a Serviced Pari Passu Companion Loan not consenting to such revision or addition, as evidenced in writing by an Opinion of Counsel, at the expense of the party requesting such amendment or as evidenced by a Rating Agency Confirmation from each of the Rating Agencies with respect to such amendment or supplement and confirmation of the applicable rating agencies that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings of any class of Serviced Companion Loan Securities, if any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement);

(viii) to modify the provisions of Sections 3.05 and 3.17 of the Pooling and Servicing Agreement (with respect to reimbursement of Nonrecoverable Advances and Workout-Delayed Reimbursement Amounts) if (a) the Depositor, the Master Servicer, the Trustee and, for so long as a Control Termination Event has not occurred and is not continuing and, with respect to any Mortgage Loans other than any Excluded Loan, as to the Directing Holder or, in the case of the Directing Certificateholder, the Holder of a majority of the Controlling Class, the Directing Holder, determine that the commercial mortgage backed securities industry standard for such provisions has changed, in order to conform to such industry standard, (b) such modification does not adversely affect the status of any Trust REMIC as a REMIC or the status of the Grantor Trust

A-26-9

as a grantor trust under the relevant provisions of the Code, as evidenced by an Opinion of Counsel and (c) each Rating Agency has delivered a Rating Agency Confirmation and, with regard to any class of Serviced Companion Loan Securities, the applicable rating agencies have delivered a confirmation that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement);

(ix) to modify the procedures of the Pooling and Servicing Agreement relating to compliance with Rule 17g-5 of the Exchange Act; provided that such amendment shall not adversely affect in any material respects the interests of any Certificateholders (including, for the avoidance of doubt, any Holders of a VRR Interest, a Y&L Towers VRR Interest or a Standard Highline VRR Interest), as evidenced by (x) an Opinion of Counsel or (y) if any Certificate is then rated, receipt of Rating Agency Confirmation from each Rating Agency rating such Certificates; and provided, further, that the Certificate Administrator shall give notice of any such amendment to the 17g-5 Information Provider for posting to the 17g-5 Information Provider’s Website pursuant to Section 3.13(c) of the Pooling and Servicing Agreement and the Certificate Administrator shall post such notice to the Certificate Administrator’s Website;

Notwithstanding the foregoing, no such amendment (A) may change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations of any Mortgage Loan Seller under any Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller or (B) may materially and adversely affect the holders of a Companion Loan without such Companion Holder’s consent.

The Pooling and Servicing Agreement may also be amended from time to time by the parties thereto with the consent of the Holders of Certificates of each Class affected by such amendment (including, for the avoidance of doubt, any Holders of the VRR Interest, the Y&L Towers VRR

A-26-10

Interest or the Standard Highline VRR Interest to the extent any such amendment would adversely affect the rights of such Certificateholders) evidencing in the aggregate not less than a majority of the aggregate Percentage Interests constituting the Class for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of the Pooling and Servicing Agreement or of modifying in any manner the rights of the Holders of Certificates of such Class; provided, however, that no such amendment shall:

(i) reduce in any manner the amount of, or delay the timing of, payments received on the Mortgage Loans or the Trust Subordinate Companion Loans that are required to be distributed on a Certificate of any class without the consent of the Holder of the Certificate or which are required to be distributed to a Companion Holder without the consent of such Companion Holder; or

(ii) reduce the aforesaid percentage of Certificates of any Class the Holders of which are required to consent to any such amendment or remove the requirement to obtain consent of any Companion Holder or Holder of Loan-Specific Certificates, in any such case, without the consent of the Holders of all Certificates of such Class then-outstanding or such Companion Holders, as applicable; or

(iii) adversely affect the Voting Rights of any Class of Certificates without the consent of the Holders of all Certificates of such Class then outstanding; or

(iv) change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations of any Mortgage Loan Seller under such Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller; or

(v) amend the Servicing Standard without the consent of 100% of the Certificateholders or receipt of Rating Agency Confirmation from each Rating Agency and confirmation of the applicable rating agencies that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings of any Serviced Companion Loan Securities, if any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement) and, if required under the related Intercreditor Agreement, the consent of the holder of any AB Subordinate Companion Loan for each Serviced AB Whole Loan.

Notwithstanding the foregoing, none of the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Depositor, the Master Servicer nor the Special Servicer will be required to consent to any amendment to the Pooling and Servicing Agreement without having first received an Opinion of Counsel (at the Trust’s expense) to the

A-26-11

effect that such amendment is permitted under the Pooling and Servicing Agreement, that all conditions precedent have been satisfied and that such amendment or the exercise of any power granted to the Master Servicer, the Special Servicer, the Depositor, the Trustee, the Certificate Administrator, the Operating Advisor, the Asset Representations Reviewer or any other specified person in accordance with such amendment will not result in the imposition of a tax on any portion of the Trust Fund or any Trust REMIC, or cause any Trust REMIC to fail to qualify as a REMIC or cause the Grantor Trust to fail to qualify as a grantor trust under the relevant provisions of the Code.

The Holders of the majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates may, in that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the Certificate Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage Loans (and all property acquired through exercise of remedies in respect of any related Mortgage Loan), the Trust Subordinate Companion Loans and the Trust’s portion of each REO Property remaining in the Trust Fund, and thereby effect termination of the Trust and early retirement of the then-outstanding Certificates, only on or after the first Distribution Date on which the aggregate Stated Principal Balances of the Mortgage Loans, the Trust Subordinate Companion Loans and the portion of any REO Loans held by the Trust is less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage Loans (solely for the purposes of this calculation, if such right is being exercised after December 2027 and the 237 East Fordham Road Mortgage Loan is still an asset of the Trust, then such Mortgage Loan will be excluded from the then-aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate Companion Loans and from the aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate Companion Loans as of the Cut-off Date) as set forth in the Pooling and Servicing Agreement.

Following the date on which the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class A-S, Class X-A, Class X-B, Class X-E, Class B and Class C Regular Interests have been reduced to zero (and provided that there is only one Holder (or multiple Holders acting in unanimity) of the then-outstanding Certificates (other than the Class Z and Class R Certificates)), the Sole Certificateholder shall have the right, with the consent of the Master Servicer, to exchange all of its Certificates (other than the Class Z and Class R Certificates) together with the payment or deemed payment of the Termination Purchase Amount for all of the Mortgage Loans, the Trust Subordinate Companion Loans and each REO Property remaining in the Trust Fund pursuant to the terms of the Pooling and Servicing Agreement.

The obligations created by the Pooling and Servicing Agreement and the Trust created thereby (other than the obligation of the Certificate Administrator to make payments to Certificateholders as provided for in the Pooling and Servicing Agreement), shall terminate upon reduction of the Certificate Balances of all the Certificates to zero (including, without limitation, any such final payment resulting from a termination of the Trust due to a sale of its property) pursuant to the terms of the Pooling and Servicing Agreement. In no event, however, will the Trust created by the Pooling and Servicing Agreement continue beyond the expiration of 21 years from the death of the last survivor of the descendants of Joseph P. Kennedy, the late Ambassador of the United States to the Court of St. James, living on the date hereof.

The Certificate Registrar has executed this Certificate on behalf of the Trust as Certificate Registrar under the Pooling and Servicing Agreement and makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates, the Mortgage Loans or the Trust Subordinate Companion Loans.

This Certificate is issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of November 1, 2017 (the “Pooling and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities Corp., as Depositor, Wells Fargo Bank, National Association, as Certificate Administrator and as Trustee, Park Bridge Lender Services LLC, as Operating Advisor and as Asset Representations Reviewer, KeyBank National Association, as Master Servicer, and CWCapital Asset Management LLC, as Special Servicer. To the extent not defined herein, capitalized terms used herein shall have the meanings assigned thereto in the Pooling and Servicing Agreement.

This Certificate represents beneficial ownership of multiple “regular interests” in a “real estate mortgage investment conduit,” as those terms are defined, respectively, in Sections 860G(a)(1) and 860D of the Internal Revenue Code of 1986, as amended.

The Certificate Administrator makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates, the Mortgage Loans or the Trust Subordinate Companion Loans and has executed this Certificate in its limited capacity as Certificate Administrator under the Pooling and Servicing Agreement.

Pursuant to the terms of the Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution on any Certificate), on the 4th Business Day following the determination date of each month, commencing in December 2017 (each such date, a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related Record Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this Certificate) of that portion of the aggregate amount of principal and interest then distributable, if any, allocable to the Class V2-UES Certificates for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement.

Interest accrued on this Certificate during an Interest Accrual Period, plus the aggregate unpaid Interest Shortfall with respect to this Certificate, if any, will be payable on the related Distribution Date to the extent provided in the Pooling and Servicing Agreement. The “Interest Accrual Period” with respect to any Distribution Date and with respect to the Class V2-UES Certificates is the calendar month immediately preceding the month in which such Distribution Date occurs and is assumed to consist of 30 days.

All distributions (other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons in whose names the Certificates are registered at the close of business on each Record Date, which will be the close of business on the last Business Day of the month immediately preceding the month in which such Distribution Date occurs.

A-26-5

Distributions are required to be made (a) by wire transfer of immediately available funds to the account of such Certificateholder at a bank or other entity having appropriate facilities therefor, if such Certificateholder provided the Certificate Administrator with written wiring instructions no less than five Business Days prior to the related Record Date (which wiring instructions may be in the form of a standing order applicable to all subsequent Distribution Dates), or otherwise (b) by check mailed to such Certificateholder at its address in the Certificate Register. The final distribution on each Certificate will be made in like manner, but only upon presentment and surrender of such Certificate at the offices of the Certificate Registrar or such other location specified in the notice to Certificateholders of such final distribution.

Any funds not distributed to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure of such Certificateholders to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited to the account or accounts of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been given pursuant to Section 4.01(l) of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within six months after the time specified in such notice, the Certificate Administrator shall mail a second notice to the remaining non tendering Certificateholders to surrender their Certificates for cancellation in order to receive the final distribution with respect thereto. If within one year after the second notice all such Certificates shall not have been surrendered for cancellation, the Certificate Administrator, directly or through an agent, shall take such steps to contact the remaining non tendering Certificateholders concerning the surrender of their Certificates as it shall deem appropriate and subject to escheatment and other applicable laws. The costs and expenses of holding such funds in trust and of contacting such Certificateholders following the first anniversary of the delivery of such second notice to the non-tendering Certificateholders shall be paid out of such funds. No interest shall accrue or be payable to any Certificateholder on any amount held in trust under the Pooling and Servicing Agreement by the Certificate Administrator as a result of such Certificateholder’s failure to surrender its Certificate(s) for final payment thereof in accordance with Section 4.01(l) of the Pooling and Servicing Agreement.

This Certificate is limited in right of payment to, among other things, certain collections and recoveries in respect of the Y&L Towers Trust Subordinate Companion Loan, as more specifically set forth herein and in the Pooling and Servicing Agreement.

As provided in the Pooling and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject to the Pooling and Servicing Agreement (including any Qualified Substitute Mortgage Loan replacing a removed Mortgage Loan) and the Trust Subordinate Companion Loans, together with the Mortgage Files relating thereto (subject to, in the case of a Serviced Whole Loan, the interests of the related Serviced Companion Noteholder in the related Mortgage File); (ii) all scheduled or unscheduled payments on or collections in respect of the Mortgage Loans and the Trust Subordinate Companion Loans due after the Cut-off Date (or with respect to a Qualified Substitute Mortgage Loan, the Due Date in the month of substitution); (iii) any REO Property (to the extent of the Trust’s interest therein) or the Trust’s beneficial interest in the Mortgaged Property securing a Non Serviced Whole Loan acquired under the related Non-Serviced PSA; (iv) all revenues received in respect of any REO Property (to the extent of the Trust’s interest therein); (v) the Master Servicer’s, the Special Servicer’s, the Certificate Administrator’s and the Trustee’s rights under the insurance policies

A-26-6

with respect to the Mortgage Loans and the Trust Subordinate Companion Loans required to be maintained pursuant to the Pooling and Servicing Agreement and any proceeds thereof (to the extent of the Trust’s interest therein); (vi) any Assignment of Leases and any security agreements (to the extent of the Trust’s interest therein); (vii) any letters of credit, indemnities, guaranties or lease enhancement policies given as additional security for any related Mortgage Loans or Trust Subordinate Companion Loans (to the extent of the Trust’s interest therein); (viii) all assets deposited in the Loss of Value Reserve Fund and the Servicing Accounts (to the extent of the Trust’s interest therein), amounts on deposit in the Collection Account (to the extent of the Trust’s interest therein), the Lower-Tier REMIC Distribution Account, the Upper-Tier REMIC Distribution Account, the Trust Subordinate Companion Loan REMIC Distribution Accounts, the Regular Interest Distribution Account, the Excess Interest Distribution Account, the Interest Reserve Account, the Gain-on-Sale Reserve Account (to the extent of the Trust’s interest therein) and any REO Account (to the extent of the Trust’s interest therein), including any reinvestment income, as applicable; (ix) any Environmental Indemnity Agreements (to the extent of the Trust’s interest therein); (x) the rights and remedies of the Depositor under each Mortgage Loan Purchase Agreement (to the extent transferred to the Trustee); (xi) the Lower-Tier Regular Interests; (xii) the Trust Subordinate Companion Loan REMIC Regular Interests; and (xiii) the proceeds of the foregoing (other than any interest earned on deposits in the lock-box accounts, cash collateral accounts, escrow accounts and any reserve accounts, to the extent such interest belongs to the related Mortgagor).

This Certificate does not purport to summarize the Pooling and Servicing Agreement, and reference is made to the Pooling and Servicing Agreement for the interests, rights, benefits, obligations and duties evidenced hereby, and the limitations thereon, and the rights, duties and immunities of the Certificate Administrator and Trustee.

As provided in the Pooling and Servicing Agreement, subject to certain restrictions on transfer set forth therein, upon surrender for registration of transfer of any Certificate, the Certificate Administrator shall execute, authenticate and deliver, in the name of the designated transferee or transferees, one or more new Certificates in authorized denominations, in like aggregate interest and of the same Class.

Prior to due presentation of this Certificate for registration of transfer, the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Certificate Registrar, and any agent of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate Registrar may treat the Person in whose name any Certificate is registered as the owner of such Certificate for the purpose of receiving distributions as provided in the Pooling and Servicing Agreement and for all other purposes whatsoever, and none of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Certificate Registrar, or any agent of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate Registrar shall be affected by any notice to the contrary.

A-26-11

Notwithstanding the foregoing, none of the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Depositor, the Master Servicer nor the Special Servicer will be required to consent to any amendment to the Pooling and Servicing Agreement without having first received an Opinion of Counsel (at the Trust’s expense) to the effect that such amendment is permitted under the Pooling and Servicing Agreement, that all conditions precedent have been satisfied and that such amendment or the exercise of any power granted to the Master Servicer, the Special Servicer, the Depositor, the Trustee, the Certificate Administrator, the Operating Advisor, the Asset Representations Reviewer or any other specified person in accordance with such amendment will not result in the imposition of a tax on any portion of the Trust Fund or any Trust REMIC, or cause any Trust REMIC to fail to qualify as a REMIC or cause the Grantor Trust to fail to qualify as a grantor trust under the relevant provisions of the Code.

The Holders of the majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates may, in that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the Certificate Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage Loans (and all property acquired through exercise of remedies in respect of any related Mortgage Loan), the Trust Subordinate Companion Loans and the Trust’s portion of each REO Property remaining in the Trust Fund, and thereby effect termination of the Trust and early retirement of the then-outstanding Certificates, only on or after the first Distribution Date on which the aggregate Stated Principal Balances of the Mortgage Loans, the Trust Subordinate Companion Loans and the portion of any REO Loans held by the Trust is less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage Loans (solely for the purposes of this calculation, if such right is being exercised after December 2027 and the 237 East Fordham Road Mortgage Loan is still an asset of the Trust, then such Mortgage Loan will be excluded from the then-aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate Companion Loans and from the aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate Companion Loans as of the Cut-off Date) as set forth in the Pooling and Servicing Agreement.

Following the date on which the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class A-S, Class X-A, Class X-B, Class X-E, Class B and Class C Regular Interests have been reduced to zero (and provided that there is only one Holder (or multiple Holders acting in unanimity) of the then-outstanding Certificates (other than the Class Z and Class R Certificates)), the Sole Certificateholder shall have the right, with the consent of the Master Servicer, to exchange all of its Certificates (other than the Class Z and Class R Certificates) together with the payment or deemed payment of the Termination Purchase Amount for all of the Mortgage Loans, the Trust Subordinate Companion Loans and each REO Property remaining in the Trust Fund pursuant to the terms of the Pooling and Servicing Agreement.

The obligations created by the Pooling and Servicing Agreement and the Trust created thereby (other than the obligation of the Certificate Administrator to make payments to Certificateholders as provided for in the Pooling and Servicing Agreement), shall terminate upon reduction of the Certificate Balances of all the Certificates to zero (including, without limitation, any such final payment resulting from a termination of the Trust due to a sale of its property) pursuant to the terms of the Pooling and Servicing Agreement. In no event, however, will the

A-26-12

Trust created by the Pooling and Servicing Agreement continue beyond the expiration of 21 years from the death of the last survivor of the descendants of Joseph P. Kennedy, the late Ambassador of the United States to the Court of St. James, living on the date hereof.

Unless the certificate of authentication hereon has been executed by the Authenticating Agent, by manual signature, this Certificate shall not be entitled to any benefit under the Pooling and Servicing Agreement or be valid for any purpose. The Certificate Registrar has executed this Certificate on behalf of the Trust as Certificate Registrar under the Pooling and Servicing Agreement and makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates, the Mortgage Loans or the Trust Subordinate Companion Loans.

Pursuant to the terms of the Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution on any Certificate), on the 4th Business Day following the determination date of each month, commencing in December 2017 (each such date, a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related Record Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this Certificate) of that portion of the aggregate amount of principal and interest then distributable, if any, allocable to the Class V1-STNA Certificates for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement.

Interest accrued on this Certificate during an Interest Accrual Period, plus the aggregate unpaid Interest Shortfall with respect to this Certificate, if any, will be payable on the related Distribution Date to the extent provided in the Pooling and Servicing Agreement. The “Interest Accrual Period” with respect to any Distribution Date and with respect to the Class V1-STNA Certificates is the calendar month immediately preceding the month in which such Distribution Date occurs and is assumed to consist of 30 days.

All distributions (other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons in whose names the Certificates are registered at the close of business on each Record Date, which will be the close of business on the last Business Day of the month immediately preceding the month in which such Distribution Date occurs. Distributions are required to be made (a) by wire transfer of immediately available funds to the

A-26-4

account of such Certificateholder at a bank or other entity having appropriate facilities therefor, if such Certificateholder provided the Certificate Administrator with written wiring instructions no less than five Business Days prior to the related Record Date (which wiring instructions may be in the form of a standing order applicable to all subsequent Distribution Dates), or otherwise (b) by check mailed to such Certificateholder at its address in the Certificate Register. The final distribution on each Certificate will be made in like manner, but only upon presentment and surrender of such Certificate at the offices of the Certificate Registrar or such other location specified in the notice to Certificateholders of such final distribution.

Any funds not distributed to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure of such Certificateholders to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited to the account or accounts of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been given pursuant to Section 4.01(l) of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within six months after the time specified in such notice, the Certificate Administrator shall mail a second notice to the remaining non tendering Certificateholders to surrender their Certificates for cancellation in order to receive the final distribution with respect thereto. If within one year after the second notice all such Certificates shall not have been surrendered for cancellation, the Certificate Administrator, directly or through an agent, shall take such steps to contact the remaining non tendering Certificateholders concerning the surrender of their Certificates as it shall deem appropriate and subject to escheatment and other applicable laws. The costs and expenses of holding such funds in trust and of contacting such Certificateholders following the first anniversary of the delivery of such second notice to the non-tendering Certificateholders shall be paid out of such funds. No interest shall accrue or be payable to any Certificateholder on any amount held in trust under the Pooling and Servicing Agreement by the Certificate Administrator as a result of such Certificateholder’s failure to surrender its Certificate(s) for final payment thereof in accordance with Section 4.01(l) of the Pooling and Servicing Agreement.

This Certificate is limited in right of payment to, among other things, certain collections and recoveries in respect of the Standard Highline Trust Subordinate Companion Loan, as more specifically set forth herein and in the Pooling and Servicing Agreement.

As provided in the Pooling and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject to the Pooling and Servicing Agreement (including any Qualified Substitute Mortgage Loan replacing a removed Mortgage Loan) and the Trust Subordinate Companion Loans, together with the Mortgage Files relating thereto (subject to, in the case of a Serviced Whole Loan, the interests of the related Serviced Companion Noteholder in the related Mortgage File); (ii) all scheduled or unscheduled payments on or collections in respect of the Mortgage Loans and the Trust Subordinate Companion Loans due after the Cut-off Date (or with respect to a Qualified Substitute Mortgage Loan, the Due Date in the month of substitution); (iii) any REO Property (to the extent of the Trust’s interest therein) or the Trust’s beneficial interest in the Mortgaged Property securing a Non Serviced Whole Loan acquired under the related Non-Serviced PSA; (iv) all revenues received in respect of any REO Property (to the extent of the Trust’s interest therein); (v) the Master Servicer’s, the Special Servicer’s, the Certificate Administrator’s and the Trustee’s rights under the insurance policies with respect to the Mortgage Loans and the Trust Subordinate Companion Loans required to be

A-26-5

maintained pursuant to the Pooling and Servicing Agreement and any proceeds thereof (to the extent of the Trust’s interest therein); (vi) any Assignment of Leases and any security agreements (to the extent of the Trust’s interest therein); (vii) any letters of credit, indemnities, guaranties or lease enhancement policies given as additional security for any related Mortgage Loans or Trust Subordinate Companion Loans (to the extent of the Trust’s interest therein); (viii) all assets deposited in the Loss of Value Reserve Fund and the Servicing Accounts (to the extent of the Trust’s interest therein), amounts on deposit in the Collection Account (to the extent of the Trust’s interest therein), the Lower-Tier REMIC Distribution Account, the Upper-Tier REMIC Distribution Account, the Trust Subordinate Companion Loan REMIC Distribution Accounts, the Regular Interest Distribution Account, the Excess Interest Distribution Account, the Interest Reserve Account, the Gain-on-Sale Reserve Account (to the extent of the Trust’s interest therein) and any REO Account (to the extent of the Trust’s interest therein), including any reinvestment income, as applicable; (ix) any Environmental Indemnity Agreements (to the extent of the Trust’s interest therein); (x) the rights and remedies of the Depositor under each Mortgage Loan Purchase Agreement (to the extent transferred to the Trustee); (xi) the Lower-Tier Regular Interests; (xii) the Trust Subordinate Companion Loan REMIC Regular Interests; and (xiii) the proceeds of the foregoing (other than any interest earned on deposits in the lock-box accounts, cash collateral accounts, escrow accounts and any reserve accounts, to the extent such interest belongs to the related Mortgagor).

This Certificate does not purport to summarize the Pooling and Servicing Agreement, and reference is made to the Pooling and Servicing Agreement for the interests, rights, benefits, obligations and duties evidenced hereby, and the limitations thereon, and the rights, duties and immunities of the Certificate Administrator and Trustee.

As provided in the Pooling and Servicing Agreement, subject to certain restrictions on transfer set forth therein, upon surrender for registration of transfer of any Certificate, the Certificate Administrator shall execute, authenticate and deliver, in the name of the designated transferee or transferees, one or more new Certificates in authorized denominations, in like aggregate interest and of the same Class.

Prior to due presentation of this Certificate for registration of transfer, the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Certificate Registrar, and any agent of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate Registrar may treat the Person in whose name any Certificate is registered as the owner of such Certificate for the purpose of receiving distributions as provided in the Pooling and Servicing Agreement and for all other purposes whatsoever, and none of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Certificate Registrar, or any agent of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate Registrar shall be affected by any notice to the contrary.

A-26-8

as a grantor trust under the relevant provisions of the Code, as evidenced by an Opinion of Counsel and (c) each Rating Agency has delivered a Rating Agency Confirmation and, with regard to any class of Serviced Companion Loan Securities, the applicable rating agencies have delivered a confirmation that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement);

(ix) to modify the procedures of the Pooling and Servicing Agreement relating to compliance with Rule 17g-5 of the Exchange Act; provided that such amendment shall not adversely affect in any material respects the interests of any Certificateholders (including, for the avoidance of doubt, any Holders of a VRR Interest, a Y&L Towers VRR Interest or a Standard Highline VRR Interest), as evidenced by (x) an Opinion of Counsel or (y) if any Certificate is then rated, receipt of Rating Agency Confirmation from each Rating Agency rating such Certificates; and provided, further, that the Certificate Administrator shall give notice of any such amendment to the 17g-5 Information Provider for posting to the 17g-5 Information Provider’s Website pursuant to Section 3.13(c) of the Pooling and Servicing Agreement and the Certificate Administrator shall post such notice to the Certificate Administrator’s Website;

Notwithstanding the foregoing, no such amendment (A) may change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations of any Mortgage Loan Seller under any Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller or (B) may materially and adversely affect the holders of a Companion Loan without such Companion Holder’s consent.

A-26-9

Interest or the Standard Highline VRR Interest to the extent any such amendment would adversely affect the rights of such Certificateholders) evidencing in the aggregate not less than a majority of the aggregate Percentage Interests constituting the Class for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of the Pooling and Servicing Agreement or of modifying in any manner the rights of the Holders of Certificates of such Class; provided, however, that no such amendment shall:

(i) reduce in any manner the amount of, or delay the timing of, payments received on the Mortgage Loans or the Trust Subordinate Companion Loans that are required to be distributed on a Certificate of any class without the consent of the Holder of the Certificate or which are required to be distributed to a Companion Holder without the consent of such Companion Holder; or

(ii) reduce the aforesaid percentage of Certificates of any Class the Holders of which are required to consent to any such amendment or remove the requirement to obtain consent of any Companion Holder or Holder of Loan-Specific Certificates, in any such case, without the consent of the Holders of all Certificates of such Class then-outstanding or such Companion Holders, as applicable; or

(iii) adversely affect the Voting Rights of any Class of Certificates without the consent of the Holders of all Certificates of such Class then outstanding; or

(v) amend the Servicing Standard without the consent of 100% of the Certificateholders or receipt of Rating Agency Confirmation from each Rating Agency and confirmation of the applicable rating agencies that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings of any Serviced Companion Loan Securities, if any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement) and, if required under the related Intercreditor Agreement, the consent of the holder of any AB Subordinate Companion Loan for each Serviced AB Whole Loan.

Notwithstanding the foregoing, none of the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Depositor, the Master Servicer nor the Special Servicer will be required to consent to any amendment to the Pooling and Servicing Agreement without having first received an Opinion of Counsel (at the Trust’s expense) to the

A-26-10

effect that such amendment is permitted under the Pooling and Servicing Agreement, that all conditions precedent have been satisfied and that such amendment or the exercise of any power granted to the Master Servicer, the Special Servicer, the Depositor, the Trustee, the Certificate Administrator, the Operating Advisor, the Asset Representations Reviewer or any other specified person in accordance with such amendment will not result in the imposition of a tax on any portion of the Trust Fund or any Trust REMIC, or cause any Trust REMIC to fail to qualify as a REMIC or cause the Grantor Trust to fail to qualify as a grantor trust under the relevant provisions of the Code.

The Holders of the majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates may, in that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the Certificate Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage Loans (and all property acquired through exercise of remedies in respect of any related Mortgage Loan), the Trust Subordinate Companion Loans and the Trust’s portion of each REO Property remaining in the Trust Fund, and thereby effect termination of the Trust and early retirement of the then-outstanding Certificates, only on or after the first Distribution Date on which the aggregate Stated Principal Balances of the Mortgage Loans, the Trust Subordinate Companion Loans and the portion of any REO Loans held by the Trust is less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage Loans (solely for the purposes of this calculation, if such right is being exercised after December 2027 and the 237 East Fordham Road Mortgage Loan is still an asset of the Trust, then such Mortgage Loan will be excluded from the then-aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate Companion Loans and from the aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate Companion Loans as of the Cut-off Date) as set forth in the Pooling and Servicing Agreement.

Following the date on which the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class A-S, Class X-A, Class X-B, Class X-E, Class B and Class C Regular Interests have been reduced to zero (and provided that there is only one Holder (or multiple Holders acting in unanimity) of the then-outstanding Certificates (other than the Class Z and Class R Certificates)), the Sole Certificateholder shall have the right, with the consent of the Master Servicer, to exchange all of its Certificates (other than the Class Z and Class R Certificates) together with the payment or deemed payment of the Termination Purchase Amount for all of the Mortgage Loans, the Trust Subordinate Companion Loans and each REO Property remaining in the Trust Fund pursuant to the terms of the Pooling and Servicing Agreement.

The obligations created by the Pooling and Servicing Agreement and the Trust created thereby (other than the obligation of the Certificate Administrator to make payments to Certificateholders as provided for in the Pooling and Servicing Agreement), shall terminate upon reduction of the Certificate Balances of all the Certificates to zero (including, without limitation, any such final payment resulting from a termination of the Trust due to a sale of its property) pursuant to the terms of the Pooling and Servicing Agreement. In no event, however, will the Trust created by the Pooling and Servicing Agreement continue beyond the expiration of 21 years from the death of the last survivor of the descendants of Joseph P. Kennedy, the late Ambassador of the United States to the Court of St. James, living on the date hereof.

The Certificate Registrar has executed this Certificate on behalf of the Trust as Certificate Registrar under the Pooling and Servicing Agreement and makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates, the Mortgage Loans or the Trust Subordinate Companion Loans.

The final distribution on each Certificate will be made in like manner, but only upon presentment and surrender of such Certificate at the offices of the Certificate Registrar or such other location specified in the notice to Certificateholders of such final distribution.

Any funds not distributed to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure of such Certificateholders to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited to the account or accounts of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been given pursuant to Section 4.01(l) of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within six months after the time specified in such notice, the Certificate Administrator shall mail a second notice to the remaining non tendering Certificateholders to surrender their Certificates for cancellation in order to receive the final distribution with respect thereto. If within one year after the second notice all such Certificates shall not have been surrendered for cancellation, the Certificate Administrator, directly or through an agent, shall take such steps to contact the remaining non tendering Certificateholders concerning the surrender of their Certificates as it shall deem appropriate and subject to escheatment and other applicable laws. The costs and expenses of holding such funds in trust and of contacting such Certificateholders following the first anniversary of the delivery of such second notice to the non-tendering Certificateholders shall be paid out of such funds. No interest shall accrue or be payable to any Certificateholder on any amount held in trust under the Pooling and Servicing Agreement by the Certificate Administrator as a result of such Certificateholder’s failure to surrender its Certificate(s) for final payment thereof in accordance with Section 4.01(l) of the Pooling and Servicing Agreement.

This Certificate is limited in right of payment to, among other things, certain collections and recoveries in respect of the Standard Highline Trust Subordinate Companion Loan, as more specifically set forth herein and in the Pooling and Servicing Agreement.

As provided in the Pooling and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject to the Pooling and Servicing Agreement (including any Qualified Substitute Mortgage Loan replacing a removed Mortgage Loan) and the Trust Subordinate Companion Loans, together with the Mortgage Files relating thereto (subject to, in the case of a Serviced Whole Loan, the interests of the related Serviced Companion Noteholder in the related Mortgage File); (ii) all scheduled or unscheduled payments on or collections in respect of the Mortgage Loans and the Trust Subordinate Companion Loans due after the Cut-off Date (or with respect to a Qualified Substitute Mortgage Loan, the Due Date in the month of substitution); (iii) any REO Property (to the extent of the Trust’s interest therein) or the Trust’s beneficial interest in the Mortgaged Property securing a Non Serviced Whole Loan acquired under the related Non-Serviced PSA; (iv) all revenues received in respect of any REO Property (to the extent of the Trust’s interest therein); (v) the Master Servicer’s, the Special Servicer’s, the Certificate Administrator’s and the Trustee’s rights under the insurance policies with respect to the Mortgage Loans and the Trust Subordinate Companion Loans required to be

 A-26-5

maintained pursuant to the Pooling and Servicing Agreement and any proceeds thereof (to the extent of the Trust’s interest therein); (vi) any Assignment of Leases and any security agreements (to the extent of the Trust’s interest therein); (vii) any letters of credit, indemnities, guaranties or lease enhancement policies given as additional security for any related Mortgage Loans or Trust Subordinate Companion Loans (to the extent of the Trust’s interest therein); (viii) all assets deposited in the Loss of Value Reserve Fund and the Servicing Accounts (to the extent of the Trust’s interest therein), amounts on deposit in the Collection Account (to the extent of the Trust’s interest therein), the Lower-Tier REMIC Distribution Account, the Upper-Tier REMIC Distribution Account, the Trust Subordinate Companion Loan REMIC Distribution Accounts, the Regular Interest Distribution Account, the Excess Interest Distribution Account, the Interest Reserve Account, the Gain-on-Sale Reserve Account (to the extent of the Trust’s interest therein) and any REO Account (to the extent of the Trust’s interest therein), including any reinvestment income, as applicable; (ix) any Environmental Indemnity Agreements (to the extent of the Trust’s interest therein); (x) the rights and remedies of the Depositor under each Mortgage Loan Purchase Agreement (to the extent transferred to the Trustee); (xi) the Lower-Tier Regular Interests; (xii) the Trust Subordinate Companion Loan REMIC Regular Interests; and (xiii) the proceeds of the foregoing (other than any interest earned on deposits in the lock-box accounts, cash collateral accounts, escrow accounts and any reserve accounts, to the extent such interest belongs to the related Mortgagor).

This Certificate does not purport to summarize the Pooling and Servicing Agreement, and reference is made to the Pooling and Servicing Agreement for the interests, rights, benefits, obligations and duties evidenced hereby, and the limitations thereon, and the rights, duties and immunities of the Certificate Administrator and Trustee.

As provided in the Pooling and Servicing Agreement, subject to certain restrictions on transfer set forth therein, upon surrender for registration of transfer of any Certificate, the Certificate Administrator shall execute, authenticate and deliver, in the name of the designated transferee or transferees, one or more new Certificates in authorized denominations, in like aggregate interest and of the same Class.

Prior to due presentation of this Certificate for registration of transfer, the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Certificate Registrar, and any agent of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate Registrar may treat the Person in whose name any Certificate is registered as the owner of such Certificate for the purpose of receiving distributions as provided in the Pooling and Servicing Agreement and for all other purposes whatsoever, and none of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Certificate Registrar, or any agent of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate Registrar shall be affected by any notice to the contrary.

 A-26-7

(vi) to revise or add any other provisions with respect to matters or questions arising under the Pooling and Servicing Agreement or any other change; provided that the required action shall not adversely affect in any material respect the interests of any Certificateholder (including, for the avoidance of doubt, any Holder of a VRR Interest, a Y&L Towers VRR Interest or a Standard Highline VRR Interest) or any holder of a Serviced Pari Passu Companion Loan not consenting to such revision or addition, as evidenced in writing by an Opinion of Counsel, at the expense of the party requesting such amendment or as evidenced by a Rating Agency Confirmation from each of the Rating Agencies with respect to such amendment or supplement and confirmation of the applicable rating agencies that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings of any class of Serviced Companion Loan Securities, if any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement);

(viii) to modify the provisions of Sections 3.05 and 3.17 of the Pooling and Servicing Agreement (with respect to reimbursement of Nonrecoverable Advances and Workout-Delayed Reimbursement Amounts) if (a) the Depositor, the Master Servicer, the Trustee and, for so long as a Control Termination Event has not occurred and is not continuing and, with respect to any Mortgage Loans other than any Excluded Loan, as to the Directing Holder or, in the case of the Directing Certificateholder, the Holder of a majority of the Controlling Class, the Directing Holder, determine that the commercial mortgage backed securities industry standard for such provisions has changed, in order to conform to such industry standard, (b) such modification does not adversely affect the status of any Trust REMIC as a REMIC or the status of the Grantor Trust

 A-26-8

as a grantor trust under the relevant provisions of the Code, as evidenced by an Opinion of Counsel and (c) each Rating Agency has delivered a Rating Agency Confirmation and, with regard to any class of Serviced Companion Loan Securities, the applicable rating agencies have delivered a confirmation that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement);

(ix) to modify the procedures of the Pooling and Servicing Agreement relating to compliance with Rule 17g-5 of the Exchange Act; provided that such amendment shall not adversely affect in any material respects the interests of any Certificateholders (including, for the avoidance of doubt, any Holders of a VRR Interest, a Y&L Towers VRR Interest or a Standard Highline VRR Interest), as evidenced by (x) an Opinion of Counsel or (y) if any Certificate is then rated, receipt of Rating Agency Confirmation from each Rating Agency rating such Certificates; and provided, further, that the Certificate Administrator shall give notice of any such amendment to the 17g-5 Information Provider for posting to the 17g-5 Information Provider’s Website pursuant to Section 3.13(c) of the Pooling and Servicing Agreement and the Certificate Administrator shall post such notice to the Certificate Administrator’s Website;

Notwithstanding the foregoing, no such amendment (A) may change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations of any Mortgage Loan Seller under any Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller or (B) may materially and adversely affect the holders of a Companion Loan without such Companion Holder’s consent.

The Pooling and Servicing Agreement may also be amended from time to time by the parties thereto with the consent of the Holders of Certificates of each Class affected by such amendment (including, for the avoidance of doubt, any Holders of the VRR Interest, the Y&L Towers VRR

 A-26-9

Interest or the Standard Highline VRR Interest to the extent any such amendment would adversely affect the rights of such Certificateholders) evidencing in the aggregate not less than a majority of the aggregate Percentage Interests constituting the Class for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of the Pooling and Servicing Agreement or of modifying in any manner the rights of the Holders of Certificates of such Class; provided, however, that no such amendment shall:

(i) reduce in any manner the amount of, or delay the timing of, payments received on the Mortgage Loans or the Trust Subordinate Companion Loans that are required to be distributed on a Certificate of any class without the consent of the Holder of the Certificate or which are required to be distributed to a Companion Holder without the consent of such Companion Holder; or

(ii) reduce the aforesaid percentage of Certificates of any Class the Holders of which are required to consent to any such amendment or remove the requirement to obtain consent of any Companion Holder or Holder of Loan-Specific Certificates, in any such case, without the consent of the Holders of all Certificates of such Class then-outstanding or such Companion Holders, as applicable; or

(iii) adversely affect the Voting Rights of any Class of Certificates without the consent of the Holders of all Certificates of such Class then outstanding; or

(iv) change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations of any Mortgage Loan Seller under such Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller; or

(v) amend the Servicing Standard without the consent of 100% of the Certificateholders or receipt of Rating Agency Confirmation from each Rating Agency and confirmation of the applicable rating agencies that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings of any Serviced Companion Loan Securities, if any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement) and, if required under the related Intercreditor Agreement, the consent of the holder of any AB Subordinate Companion Loan for each Serviced AB Whole Loan.

Notwithstanding the foregoing, none of the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Depositor, the Master Servicer nor the Special Servicer will be required to consent to any amendment to the Pooling and Servicing Agreement without having first received an Opinion of Counsel (at the Trust’s expense) to the

 A-26-10

effect that such amendment is permitted under the Pooling and Servicing Agreement, that all conditions precedent have been satisfied and that such amendment or the exercise of any power granted to the Master Servicer, the Special Servicer, the Depositor, the Trustee, the Certificate Administrator, the Operating Advisor, the Asset Representations Reviewer or any other specified person in accordance with such amendment will not result in the imposition of a tax on any portion of the Trust Fund or any Trust REMIC, or cause any Trust REMIC to fail to qualify as a REMIC or cause the Grantor Trust to fail to qualify as a grantor trust under the relevant provisions of the Code.

The Holders of the majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates may, in that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the Certificate Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage Loans (and all property acquired through exercise of remedies in respect of any related Mortgage Loan), the Trust Subordinate Companion Loans and the Trust’s portion of each REO Property remaining in the Trust Fund, and thereby effect termination of the Trust and early retirement of the then-outstanding Certificates, only on or after the first Distribution Date on which the aggregate Stated Principal Balances of the Mortgage Loans, the Trust Subordinate Companion Loans and the portion of any REO Loans held by the Trust is less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage Loans (solely for the purposes of this calculation, if such right is being exercised after December 2027 and the 237 East Fordham Road Mortgage Loan is still an asset of the Trust, then such Mortgage Loan will be excluded from the then-aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate Companion Loans and from the aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate Companion Loans as of the Cut-off Date) as set forth in the Pooling and Servicing Agreement.

Following the date on which the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class A-S, Class X-A, Class X-B, Class X-E, Class B and Class C Regular Interests have been reduced to zero (and provided that there is only one Holder (or multiple Holders acting in unanimity) of the then-outstanding Certificates (other than the Class Z and Class R Certificates)), the Sole Certificateholder shall have the right, with the consent of the Master Servicer, to exchange all of its Certificates (other than the Class Z and Class R Certificates) together with the payment or deemed payment of the Termination Purchase Amount for all of the Mortgage Loans, the Trust Subordinate Companion Loans and each REO Property remaining in the Trust Fund pursuant to the terms of the Pooling and Servicing Agreement.

The obligations created by the Pooling and Servicing Agreement and the Trust created thereby (other than the obligation of the Certificate Administrator to make payments to Certificateholders as provided for in the Pooling and Servicing Agreement), shall terminate upon reduction of the Certificate Balances of all the Certificates to zero (including, without limitation, any such final payment resulting from a termination of the Trust due to a sale of its property) pursuant to the terms of the Pooling and Servicing Agreement. In no event, however, will the Trust created by the Pooling and Servicing Agreement continue beyond the expiration of 21 years from the death of the last survivor of the descendants of Joseph P. Kennedy, the late Ambassador of the United States to the Court of St. James, living on the date hereof.

This Certificate is issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of November 1, 2017 (the “Pooling and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities Corp., as Depositor, Wells Fargo Bank, National Association, as Certificate Administrator and as Trustee, Park Bridge Lender Services LLC, as Operating Advisor and as Asset Representations Reviewer, KeyBank National Association, as Master Servicer, and CWCapital Asset Management LLC, as Special Servicer. To the extent not defined herein, capitalized terms used herein shall have the meanings assigned thereto in the Pooling and Servicing Agreement.

This Certificate represents beneficial ownership of multiple “regular interests” in a “real estate mortgage investment conduit,” as those terms are defined, respectively, in Sections 860G(a)(1) and 860D of the Internal Revenue Code of 1986, as amended.

The Certificate Administrator makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates, the Mortgage Loans or the Trust Subordinate Companion Loans and has executed this Certificate in its limited capacity as Certificate Administrator under the Pooling and Servicing Agreement.

Pursuant to the terms of the Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution on any Certificate), on the 4th Business Day following the determination date of each month, commencing in December 2017 (each such date, a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related Record Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this Certificate) of that portion of the aggregate amount of principal and interest then distributable, if any, allocable to the Class V2-STN Certificates for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement.

Interest accrued on this Certificate during an Interest Accrual Period, plus the aggregate unpaid Interest Shortfall with respect to this Certificate, if any, will be payable on the related Distribution Date to the extent provided in the Pooling and Servicing Agreement. The “Interest Accrual Period” with respect to any Distribution Date and with respect to the Class V2-STN Certificates is the calendar month immediately preceding the month in which such Distribution Date occurs and is assumed to consist of 30 days.

All distributions (other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons in whose names the Certificates are registered at the close of business on each Record Date, which will be the close of business on the last Business

 A-26-4

Day of the month immediately preceding the month in which such Distribution Date occurs. Distributions are required to be made (a) by wire transfer of immediately available funds to the account of such Certificateholder at a bank or other entity having appropriate facilities therefor, if such Certificateholder provided the Certificate Administrator with written wiring instructions no less than five Business Days prior to the related Record Date (which wiring instructions may be in the form of a standing order applicable to all subsequent Distribution Dates), or otherwise (b) by check mailed to such Certificateholder at its address in the Certificate Register. The final distribution on each Certificate will be made in like manner, but only upon presentment and surrender of such Certificate at the offices of the Certificate Registrar or such other location specified in the notice to Certificateholders of such final distribution.

Any funds not distributed to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure of such Certificateholders to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited to the account or accounts of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been given pursuant to Section 4.01(l) of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within six months after the time specified in such notice, the Certificate Administrator shall mail a second notice to the remaining non tendering Certificateholders to surrender their Certificates for cancellation in order to receive the final distribution with respect thereto. If within one year after the second notice all such Certificates shall not have been surrendered for cancellation, the Certificate Administrator, directly or through an agent, shall take such steps to contact the remaining non tendering Certificateholders concerning the surrender of their Certificates as it shall deem appropriate and subject to escheatment and other applicable laws. The costs and expenses of holding such funds in trust and of contacting such Certificateholders following the first anniversary of the delivery of such second notice to the non-tendering Certificateholders shall be paid out of such funds. No interest shall accrue or be payable to any Certificateholder on any amount held in trust under the Pooling and Servicing Agreement by the Certificate Administrator as a result of such Certificateholder’s failure to surrender its Certificate(s) for final payment thereof in accordance with Section 4.01(l) of the Pooling and Servicing Agreement.

This Certificate is limited in right of payment to, among other things, certain collections and recoveries in respect of the Standard Highline Trust Subordinate Companion Loan, as more specifically set forth herein and in the Pooling and Servicing Agreement.

This Certificate does not purport to summarize the Pooling and Servicing Agreement, and reference is made to the Pooling and Servicing Agreement for the interests, rights, benefits, obligations and duties evidenced hereby, and the limitations thereon, and the rights, duties and immunities of the Certificate Administrator and Trustee.

As provided in the Pooling and Servicing Agreement, subject to certain restrictions on transfer set forth therein, upon surrender for registration of transfer of any Certificate, the Certificate Administrator shall execute, authenticate and deliver, in the name of the designated transferee or transferees, one or more new Certificates in authorized denominations, in like aggregate interest and of the same Class.

(vi) to revise or add any other provisions with respect to matters or questions arising under the Pooling and Servicing Agreement or any other change; provided that the required action shall not adversely affect in any material respect the interests of any Certificateholder (including, for the avoidance of doubt, any Holder of a VRR Interest, a Y&L Towers VRR Interest or a Standard Highline VRR Interest) or any holder of a Serviced Pari Passu Companion Loan not consenting to such revision or addition, as evidenced in writing by an Opinion of Counsel, at the expense of the party requesting such amendment or as evidenced by a Rating Agency Confirmation from each of the Rating Agencies with respect to such amendment or supplement and confirmation of the applicable rating agencies that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings of any class of Serviced Companion Loan Securities, if any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement);

(ix) to modify the procedures of the Pooling and Servicing Agreement relating to compliance with Rule 17g-5 of the Exchange Act; provided that such amendment shall not adversely affect in any material respects the interests of any Certificateholders (including, for the avoidance of doubt, any Holders of a VRR Interest, a Y&L Towers VRR Interest or a Standard Highline VRR Interest), as evidenced by (x) an Opinion of Counsel or (y) if any Certificate is then rated, receipt of Rating Agency Confirmation from each Rating Agency rating such Certificates; and provided, further, that the Certificate Administrator shall give notice of any such amendment to the 17g-5 Information Provider for posting to the 17g-5 Information Provider’s Website pursuant to Section 3.13(c) of the Pooling and Servicing Agreement and the Certificate Administrator shall post such notice to the Certificate Administrator’s Website;

Notwithstanding the foregoing, no such amendment (A) may change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations of any Mortgage Loan Seller under any Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller or (B) may materially and adversely affect the holders of a Companion Loan without such Companion Holder’s consent.

 A-26-9

The Pooling and Servicing Agreement may also be amended from time to time by the parties thereto with the consent of the Holders of Certificates of each Class affected by such amendment (including, for the avoidance of doubt, any Holders of the VRR Interest, the Y&L Towers VRR Interest or the Standard Highline VRR Interest to the extent any such amendment would adversely affect the rights of such Certificateholders) evidencing in the aggregate not less than a majority of the aggregate Percentage Interests constituting the Class for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of the Pooling and Servicing Agreement or of modifying in any manner the rights of the Holders of Certificates of such Class; provided, however, that no such amendment shall:

(i) reduce in any manner the amount of, or delay the timing of, payments received on the Mortgage Loans or the Trust Subordinate Companion Loans that are required to be distributed on a Certificate of any class without the consent of the Holder of the Certificate or which are required to be distributed to a Companion Holder without the consent of such Companion Holder; or

(ii) reduce the aforesaid percentage of Certificates of any Class the Holders of which are required to consent to any such amendment or remove the requirement to obtain consent of any Companion Holder or Holder of Loan-Specific Certificates, in any such case, without the consent of the Holders of all Certificates of such Class then-outstanding or such Companion Holders, as applicable; or

 A-26-10

Notwithstanding the foregoing, none of the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Depositor, the Master Servicer nor the Special Servicer will be required to consent to any amendment to the Pooling and Servicing Agreement without having first received an Opinion of Counsel (at the Trust’s expense) to the effect that such amendment is permitted under the Pooling and Servicing Agreement, that all conditions precedent have been satisfied and that such amendment or the exercise of any power granted to the Master Servicer, the Special Servicer, the Depositor, the Trustee, the Certificate Administrator, the Operating Advisor, the Asset Representations Reviewer or any other specified person in accordance with such amendment will not result in the imposition of a tax on any portion of the Trust Fund or any Trust REMIC, or cause any Trust REMIC to fail to qualify as a REMIC or cause the Grantor Trust to fail to qualify as a grantor trust under the relevant provisions of the Code.

The Holders of the majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates may, in that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the Certificate Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage Loans (and all property acquired through exercise of remedies in respect of any related Mortgage Loan), the Trust Subordinate Companion Loans and the Trust’s portion of each REO Property remaining in the Trust Fund, and thereby effect termination of the Trust and early retirement of the then-outstanding Certificates, only on or after the first Distribution Date on which the aggregate Stated Principal Balances of the Mortgage Loans, the Trust Subordinate Companion Loans and the portion of any REO Loans held by the Trust is less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage Loans (solely for the purposes of this calculation, if such right is being exercised after December 2027 and the 237 East Fordham Road Mortgage Loan is still an asset of the Trust, then such Mortgage Loan will be excluded from the then-aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate Companion Loans and from the aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate Companion Loans as of the Cut-off Date) as set forth in the Pooling and Servicing Agreement.

Following the date on which the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class A-S, Class X-A, Class X-B, Class X-E, Class B and Class C Regular Interests have been reduced to zero (and provided that there is only one Holder (or multiple Holders acting in unanimity) of the then-outstanding Certificates (other than the Class Z and Class R Certificates)), the Sole Certificateholder shall have the right, with the consent of the Master Servicer, to exchange all of its Certificates (other than the Class Z and Class R Certificates) together with the payment or deemed payment of the Termination Purchase Amount for all of the Mortgage Loans, the Trust Subordinate Companion Loans and each REO Property remaining in the Trust Fund pursuant to the terms of the Pooling and Servicing Agreement.

The obligations created by the Pooling and Servicing Agreement and the Trust created thereby (other than the obligation of the Certificate Administrator to make payments to Certificateholders as provided for in the Pooling and Servicing Agreement), shall terminate upon reduction of the Certificate Balances of all the Certificates to zero (including, without limitation, any such final payment resulting from a termination of the Trust due to a sale of its property) pursuant to the terms of the Pooling and Servicing Agreement. In no event, however, will the

 A-26-11

Trust created by the Pooling and Servicing Agreement continue beyond the expiration of 21 years from the death of the last survivor of the descendants of Joseph P. Kennedy, the late Ambassador of the United States to the Court of St. James, living on the date hereof.

Unless the certificate of authentication hereon has been executed by the Authenticating Agent, by manual signature, this Certificate shall not be entitled to any benefit under the Pooling and Servicing Agreement or be valid for any purpose. The Certificate Registrar has executed this Certificate on behalf of the Trust as Certificate Registrar under the Pooling and Servicing Agreement and makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates, the Mortgage Loans or the Trust Subordinate Companion Loans.

Re: Transfer of CSAIL 2017-CX10 Commercial Mortgage Trust, Commercial Mortgage Pass Through Certificates, Series 2017-CX10

Ladies and Gentlemen:

This letter is delivered pursuant to Section 5.03 of the Pooling and Servicing Agreement, dated as of November 1, 2017 (the “Pooling and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities Corp., as Depositor, KeyBank National Association, as Master Servicer, Wells Fargo Bank, National Association, as Certificate Administrator and as Trustee, CWCapital Asset Management LLC, as Special Servicer, and Park Bridge Lender Services LLC, as Asset Representations Reviewer and as Operating Advisor, on behalf of the holders of CSAIL 2017-CX10 Commercial Mortgage Trust, Commercial Mortgage Pass Through Certificates, Series 2017-CX10 (the “Certificates”) in connection with the transfer by _________________ (the “Seller”) to the undersigned (the “Purchaser”) of $_______________ aggregate Certificate Balance of Class ___ Certificates (the “Certificate”). Capitalized terms used and not otherwise defined herein shall have the respective meanings ascribed to such terms in the Pooling and Servicing Agreement.

In connection with such transfer, the Purchaser hereby represents and warrants to you and the addressees hereof as follows:

1.       Check one of the following:^*

☐ The Purchaser is not purchasing a Class R Certificate and the Purchaser is an institution that is an “accredited investor” (an “Institutional Accredited Investor”) within the meaning of Rule 501(a)(1), (2), (3) or (7) of Regulation D under the Securities Act of 1933, as amended (the “Securities Act”) or any entity in which

^* Purchaser must include one of the following two certifications.

Exhibit C-1

The Purchaser is acquiring the Certificates purchased by it for its own account or for one or more accounts, each of which is an Institutional Accredited Investor, as to each of which the Purchaser exercises sole investment discretion. The Purchaser hereby undertakes to reimburse the Trust Fund for any costs incurred by it in connection with this transfer.

☐ The Purchaser is a “qualified institutional buyer” (a “QIB”) within the meaning of Rule 144A (“Rule 144A”) under the Securities Act. The Purchaser is aware that the transfer is being made in reliance on Rule 144A, and the Purchaser has had the opportunity to obtain the information required to be provided pursuant to paragraph (d)(4)(i) of Rule 144A.

2.       The Purchaser’s intention is to acquire the Certificate (a) for investment for the Purchaser’s own account or (b) for reoffer, resale, pledge or other transfer (i) to QIBs in transactions under Rule 144A, and not in any event with the view to, or for resale in connection with, any distribution thereof, or (ii) (other than with respect to any Class R, Class UES-A, Class UES-B, Class UES-C, Class UES-D, Class UES-X, Class STN-A, Class STN-B, Class STN-X or Class STN-C Certificate) to Institutional Accredited Investors, subject in the case of clause (ii) above to (w) the receipt by the Certificate Registrar of a letter substantially in the form hereof, (x) the receipt by the Certificate Registrar of an opinion of counsel acceptable to the Trustee and Certificate Registrar that such reoffer, resale, pledge or transfer is in compliance with the Securities Act, (y) the receipt by the Certificate Registrar of such other evidence acceptable to the Certificate Registrar that such reoffer, resale, pledge or transfer is in compliance with the Securities Act and other applicable laws and (z) a written undertaking to reimburse the Trust Fund for any costs incurred by it in connection with the proposed transfer. The Purchaser understands that the Certificate (and any subsequent Certificate) has not been registered under the Securities Act, by reason of a specified exemption from the registration provisions of the Securities Act which depends upon, among other things, the bona fide nature of the Purchaser’s investment intent (or intent to reoffer, resell, pledge or transfer the Certificate only to certain investors in certain exempted transactions) as expressed herein.

3.       The Purchaser has reviewed the Preliminary Prospectus and the Prospectus relating to the Offered Certificates (collectively, the “Prospectus”) (and, with respect to Offered Private Certificates, the Preliminary Offering Circular and the Final Offering Circular related to such Offered Private Certificates and, with respect to the Yorkshire & Lexington Towers Loan-Specific Certificates and the Standard Highline Loan-Specific Certificates, the Preliminary Loan-Specific Offering Circular and the Final Loan-Specific Offering Circular related to such Loan-Specific Certificates) and the agreements and other materials referred to therein and has had the opportunity to ask questions and receive answers concerning the terms and conditions of the transactions contemplated by the Prospectus.

Exhibit C-2

4.       The Purchaser acknowledges that the Certificate (and any Certificate issued on transfer or exchange thereof) has not been registered or qualified under the Securities Act or the securities laws of any State or any other jurisdiction, and that the Certificate cannot be reoffered, resold, pledged or otherwise transferred unless it is registered or qualified thereunder or unless an exemption from such registration or qualification is available.

5.       The Purchaser hereby undertakes to be bound by the terms and conditions of the Pooling and Servicing Agreement in its capacity as an owner of a Certificate or Certificates, as the case may be (each, a “Certificateholder”), in all respects as if it were a signatory thereto. This undertaking is made for the benefit of the Trust, the Certificate Registrar and all Certificateholders present and future.

COUNTY OF	)

I, [______], under penalties of perjury, declare that, to the best of my knowledge and belief, the following representations are true, correct and complete, and being first sworn, depose and say that:

1.       I am a [______] of [______] (the “Purchaser”), on behalf of which I have the authority to make this affidavit.

2.       The Purchaser is acquiring Class R Certificates representing [__]% of the residual interest in each of the real estate mortgage investment conduits (each, a “REMIC”) designated as the (i) “Lower-Tier REMIC”, (ii) “Upper-Tier REMIC”, (iii) “Y&L Towers Trust Subordinate Companion Loan REMIC” and (iv) “Standard Highline Trust Subordinate Companion Loan REMIC”, respectively, relating to the Certificates for which an election is to be made under Section 860D of the Internal Revenue Code of 1986 (the “Code”).

3.       The Purchaser is not a Disqualified Organization (as defined below), and that the Purchaser is not acquiring the Class R Certificates for the account of, or as agent or nominee of, or with a view to the transfer of direct or indirect record or beneficial ownership

Exhibit D-1-1

thereof, to a Disqualified Organization. For the purposes hereof, a “Disqualified Organization” is any of the following: (i) the United States, any State or political subdivision thereof, any possession of the United States or any agency or instrumentality of any of the foregoing (other than an instrumentality which is a corporation if all of its activities are subject to tax and, except for Freddie Mac, a majority of its board of directors is not selected by such governmental unit), (ii) a foreign government, any international organization or any agency or instrumentality of any of the foregoing, (iii) any organization which is exempt from the tax imposed by Chapter 1 of the Code (including the tax imposed by Section 511 of the Code on unrelated business taxable income) on any excess inclusions (as defined in Section 860E(c)(1) of the Code) with respect to the Class R Certificates (except certain farmers’ cooperatives described in Section 521 of the Code), (iv) rural electric and telephone cooperatives described in Section 1381(a)(2)(C) of the Code, (v) an “electing large partnership”, as defined in Section 775 of the Code and (vi) any other Person so designated by the Trustee or the Certificate Administrator based upon an Opinion of Counsel as provided to the Trustee or the Certificate Administrator (at no expense to the Trustee or the Certificate Administrator) that the holding of an Ownership Interest in a Class R Certificate by such Person may cause any Trust REMIC to fail to qualify as a REMIC at any time that the Certificates are outstanding or any Person having an Ownership Interest in any Class of Certificates (other than such Person) to incur a liability for any federal tax imposed under the Code that would not otherwise be imposed but for the Transfer of an Ownership Interest in a Class R Certificate to such Person. The terms “United States,” “State” and “international organization” shall have the meanings set forth in Section 7701 of the Code or successor provisions.

4.       The Purchaser acknowledges that Section 860E(e) of the Code would impose a substantial tax on the transferor or, in certain circumstances, on an agent for the transferee, with respect to any transfer of any interest in any Class R Certificates to a Disqualified Organization.

5.       The Purchaser is a Permitted Transferee and, to the extent applicable, the Purchaser’s U.S. taxpayer identification number is [__________].

6.       No purpose of the acquisition of the Class R Certificates is to impede the assessment or collection of tax.

7.       The Purchaser will not cause income from the Class R Certificate to be attributable to a foreign permanent establishment or fixed base, within the meaning of an applicable income tax treaty, of the Purchaser or any other person.

8.       Check the applicable paragraph:

☐      The present value of the anticipated tax liabilities associated with holding the Class R Certificate, as applicable, does not exceed the sum of:

(i)      the present value of any consideration given to the Purchaser to acquire such Class R Certificate; 

(ii)     the present value of the expected future distributions on such Class R Certificate; and

Exhibit D-1-2

(iii)    the present value of the anticipated tax savings associated with holding such Class R Certificate as the related REMIC generates losses.

For purposes of this calculation, (i) the Purchaser is assumed to pay tax at the highest rate currently specified in Section 11(b) of the Code (but the tax rate in Section 55(b)(1)(B) of the Code may be used in lieu of the highest rate specified in Section 11(b) of the Code if the Purchaser has been subject to the alternative minimum tax under Section 55 of the Code in the preceding two years and will compute its taxable income in the current taxable year using the alternative minimum tax rate) and (ii) present values are computed using a discount rate equal to the short-term Federal rate prescribed by Section 1274(d) of the Code for the month of the transfer and the compounding period used by the Purchaser.

☐      The transfer of the Class R Certificate complies with U.S. Treasury Regulations Sections 1.860E-1(c)(5) and (6) and, accordingly,

(i)      the Purchaser is an “eligible corporation,” as defined in U.S. Treasury Regulations Section 1.860E-1(c)(6)(i), as to which income from the Class R Certificate will only be taxed in the United States;

(ii)     at the time of the transfer, and at the close of the Purchaser’s two fiscal years preceding the year of the transfer, the Purchaser had gross assets for financial reporting purposes (excluding any obligation of a person related to the Purchaser within the meaning of U.S. Treasury Regulations Section 1.860E-1(c)(6)(ii)) in excess of $100 million and net assets in excess of $10 million;

(iii)    the Purchaser will transfer the Class R Certificate only to another “eligible corporation,” as defined in Treasury Regulations Section 1.860E-1(c)(6)(i), in a transaction that satisfies the requirements of Sections 1.860E-1(c)(4)(i), (ii) and (iii) and Treasury Regulations Section 1.860E-1(c)(5); and

(iv)    the Purchaser determined the consideration paid to it to acquire the Class R Certificate based on reasonable market assumptions (including, but not limited to, borrowing and investment rates, prepayment and loss assumptions, expense and reinvestment assumptions, tax rates and other factors specific to the Purchaser) that it has determined in good faith.

☐      None of the above.

9.       The Purchaser historically has paid its debts as they have come due and intends to pay its debts as they come due in the future and the Purchaser intends to pay taxes associated with holding the Class R Certificates as they become due.

10.     The Purchaser understands that it may incur tax liabilities with respect to the Class R Certificate in excess of any cash flows generated by such Certificate.

11.    The Purchaser is aware that the Certificate Registrar will not register any transfer of a Class R Certificate by the Transferor unless the Purchaser, or such Purchaser’s agent, delivers to the Certificate Registrar, among other things, an affidavit and agreement in substantially the same form as this affidavit and agreement. The Purchaser expressly agrees that

Exhibit D-1-3

it will not consummate any such transfer if it knows or believes that any representation contained in such affidavit and agreement is false.

12.    The Purchaser represents that it is not acquiring the Class R Certificate as a nominee, trustee or agent for any person that is not a Permitted Transferee and that for so long as it retains its interest in the Class R Certificate, it will endeavor to remain a Permitted Transferee.

13.    The Purchaser consents to any additional restrictions or arrangements that shall be deemed necessary upon advice of counsel to constitute a reasonable arrangement to ensure that the Class R Certificate will only be owned, directly or indirectly, by a Permitted Transferee.

14.    The Purchaser has reviewed the provisions of Section 5.03 of the Pooling and Servicing Agreement, a description of which provisions is set forth in the Class R Certificates; and the Purchaser expressly agrees to be bound by and to comply with such provisions.

15.    The Purchaser consents to the designation of the Certificate Administrator as the agent of the “tax matters person” and “partnership representative” of each Trust REMIC pursuant to Section 10.01 of the Pooling and Servicing Agreement.

Capitalized terms used but not defined herein have the meanings assigned thereto in the Pooling and Servicing Agreement.

Ladies and Gentlemen:

This letter is delivered to you in connection with the transfer by [______] (the “Transferor”) to [______] (the “Transferee”) of Class R Certificates evidencing a [__]% Percentage Interest in such Class (the “Residual Certificates”). The Certificates, including the Residual Certificates, were issued pursuant to the Pooling and Servicing Agreement, dated as of November 1, 2017 (the “Pooling and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities Corp., as Depositor, KeyBank National Association, as Master Servicer, Wells Fargo Bank, National Association, as Certificate Administrator and as Trustee, CWCapital Asset Management LLC, as Special Servicer, and Park Bridge Lender Services LLC, as Asset Representations Reviewer and as Operating Advisor.

The Transferor hereby certifies, represents and warrants to you, as Certificate Registrar, that:

(1)       No purpose of the Transferor relating to the transfer of the Residual Certificates by the Transferor to the Transferee is or will be to impede the assessment or collection of any tax.

(3)       The Transferor has at the time of this transfer conducted a reasonable investigation of the financial condition of the Transferee as contemplated by Treasury regulation Section 1.860E-1(c)(4)(i) and, as a result of that investigation, the Transferor has determined that the Transferee has historically paid its debts as they became due and has found no significant evidence to indicate that the Transferee will not continue to pay its debts as they become due in the future. The Transferor understands that the transfer of the Residual Certificates may not be

respected for United States income tax purposes (and the Transferor may continue to be liable for United States income taxes associated therewith) unless the Transferor has conducted such an investigation.

Re: Access to Certain Information Regarding CSAIL 2017-CX10 Commercial Mortgage Trust, Commercial Mortgage Pass Through Certificates, Series 2017-CX10

Ladies and Gentlemen:

Reference is hereby made to that certain Pooling and Servicing Agreement dated as of November 1, 2017 (the “Pooling and Servicing Agreement”), among the Credit Suisse Commercial Mortgage Securities Corp., as Depositor, KeyBank National Association, as Master Servicer, CWCapital Asset Management LLC, as Special Servicer, Wells Fargo Bank, National Association, as Certificate Administrator and as Trustee, and Park Bridge Lender Services LLC, as Asset Representations Reviewer and as Operating Advisor. Defined terms used herein and not otherwise defined shall have the meanings set forth in the Pooling and Servicing Agreement.

KeyBank National Association (“KeyBank”)/CWCapital Asset Management LLC (“CWCapital”) understands that [____] (the “Company”) is requesting certain confidential or non-public information relating to the Mortgage Loans and the Trust Subordinate Companion Loans to which the Company has continuing rights as a Certificateholder. The Company is requesting such information for the purpose of analyzing asset performance and evaluating any continuing rights the Company may have under the Trust (the “Permitted Purpose”). The

Exhibit X-1

[_____] [__], 20[__]
Page 2

Company agrees that the Permitted Purpose shall not include the use or disclosure of the Confidential Information (as defined below) in any manner that violates any applicable law, the Pooling and Servicing Agreement or the related mortgage loan documents.

KeyBank/CWCapital will provide the Company with certain confidential, non-public servicing information (the “Confidential Information”) pertaining to the Mortgage Loans and the related Mortgaged Properties and borrowers. The Company acknowledges that the Confidential Information (a) includes or may be based upon information provided to KeyBank/CWCapital by third parties, (b) may not have been verified by KeyBank/CWCapital, and (c) may be incomplete or contain inaccuracies. The Company agrees that KeyBank/CWCapital, the [“Master Servicer”/”Special Servicer”] (as defined in the Pooling and Servicing Agreement) and their respective Representatives (as defined below) shall not have any liability to the Company or its Representatives resulting from (x) any inaccuracies or omissions in the Confidential Information, (y) any use of the Confidential Information, or (z) KeyBank/CWCapital’s failure or inability to provide the Confidential Information to the Company for any reason. Notwithstanding the foregoing, the following will not constitute “Confidential Information” for purposes of this letter agreement: (a) information that was already in Company’s possession prior to its receipt from KeyBank/CWCapital; (b) information that is obtained by Company from a third person who, insofar as is known to Company, is not prohibited from transmitting the information to Company by a contractual, legal or fiduciary obligation to KeyBank/CWCapital; (c) information that is or becomes publicly available through no fault of Company; and (d) information that is independently developed by Company. The term “Representatives” with respect to any entity shall mean the officers, directors, general partners, employees, agents, affiliates, auditors and legal counsel (which may be internal counsel) of that entity.

The Company may have access to the Confidential Information through (at KeyBank/CWCapital’s election): (i) responses to reasonable written inquiries received from the Company, (ii) conference calls conducted on a reasonably scheduled basis with KeyBank/CWCapital’s surveillance group, or (iii) direct on-line access (read-only capacity) to the information available on the applicable [____] system or any successor or replacement system (“System”). KeyBank/CWCapital may cease or defer providing the Company with Confidential Information in the event that (a) the Company or its Representatives violate any provision hereof, or (b) KeyBank/CWCapital determines (in its sole discretion) that such termination is necessary for any reason, including its determination that such action is required pursuant to the terms of the Pooling and Servicing Agreement, the related Mortgage Loan documents, or any applicable law. KeyBank/CWCapital shall cease to provide the Company with Confidential Information if KeyBank/CWCapital has actual knowledge that the Company or its Representatives are affiliates of any borrower under the Mortgage Loan documents and KeyBank/CWCapital determines that the provision, notice or access to such Confidential Information would violate the accepted servicing practices or servicing standards as defined in the Pooling and Servicing Agreement.

ASSET REVIEW PROCEDURES

Subject to the Pooling and Servicing Agreement, this Exhibit sets forth Asset Representations Reviewer’s review procedures for each Delinquent Loan based on the information provided for an Asset Review. Capitalized terms used herein and not defined herein shall have the meanings ascribed to them in the Pooling and Servicing Agreement. In the event of any conflict between this Exhibit QQ and the terms of the Pooling and Servicing Agreement, the Pooling and Servicing Agreement shall control and govern the Asset Representation Reviewer’s responsibilities and duties with respect to Asset Reviews.

Call for Review and Collection and Inventory of Review Materials 

Step 1 Asset Representations Reviewer (“ARR”) receives the following items before beginning its review from the parties specified in Section [ ] of the Pooling and Servicing Agreement:

■ Notice of Asset Review Trigger (with attachments)

■ Asset Review Vote Election

■ Notice of Affirmative Asset Review Vote

■ List of all Delinquent Loans subject to the Asset Review

■ Review Materials for each Delinquent Loan via Secure Data Room access, including the Diligence File

■ Any Unsolicited Information (if applicable)

Step 2 For each Delinquent Loan, ARR inventories all Review Materials to which ARR is provided access in the Secure Data Room to determine what, if any, Review Materials for such Delinquent Loan are missing, using the list of documents in Section [ ] through Section [ ] of this Agreement, any comparable lists included in the related Mortgage Loan Purchase Agreement, and any closing checklist from the origination of such Delinquent Loan, to guide its review and determination

Step 3 If ARR determines that the information made available to it in the Secure Data Room with respect to any Delinquent Loan is missing any documents required to complete an Asset Review of such Delinquent Loan, ARR shall prepare a list of such missing documents and notify Master Servicer (with respect to Non-Specially Serviced Loans) and Special Servicer (with respect to Specially Serviced Loans) of such missing documents. If the Master Servicer or Special Servicer, as applicable, does not provide such document as provided in the Pooling and Servicing Agreement, the ARR shall notify the related Mortgage Loan Seller of such missing information 

Exhibit QQ-1

Analysis and Testing of Representations and Warranties

Step 4 For each Delinquent Loan for which ARR has received all Review Materials required to complete an Asset Review of such Delinquent Loan, ARR tests such Delinquent Loan for compliance with each representation and warranty made by the related Mortgage Loan Seller with respect to such Delinquent Loan as follows:

■ ARR reviews each representation and warranty and each item included in the Review Materials applicable or related to such representation or warranty to determine whether there is any evidence that such representation or warranty was not true when made by the related Mortgage Loan Seller

■ For each representation and warranty, ARR lists

● all items from the Review Materials reviewed or used in its testing of such representation and warranty

● whether ARR has determined that there is any evidence that such representation or warranty was not true when made by the related Mortgage Loan Seller, and

○ if so, stating the aspect of the applicable representation or warranty that does not appear to have been true when made by the related Mortgage Loan Seller and ARR’s basis for its conclusion

○ completing the Asset Review Report by setting forth, for each Delinquent Loan, the information contemplated herein with respect to each representation and warranty

ARR will not attempt (and has no obligation) to determine the materiality of any potential breach of a representation or warranty that it discovers evidence of during its review as contemplated herein.
