Item 1.01 Entry into a Material Definitive Agreement.

On May 5, 2017, Blackstone Mortgage Trust, Inc. (the “Company”) completed its registered underwritten public offering of $250.0 million aggregate principal amount of its 4.375% Convertible Senior Notes due 2022 (the “Notes”) pursuant to an underwriting agreement, dated May 1, 2017, among the Company, BXMT Advisors L.L.C. and Citigroup Global Markets Inc. and Morgan Stanley & Co. LLC, as representatives of the several underwriters named in Schedule II thereto (the “Underwriters”). Pursuant to the terms of the underwriting agreement, the Company also granted the Underwriters a 30-day option to purchase up to an additional $37.5 million aggregate principal amount of the Notes solely to cover overallotments, if any. The Notes were sold pursuant to the Company’s effective shelf registration statement on Form S-3ASR (File No. 333-212769) filed on July 29, 2016 and the related prospectus dated July 29, 2016, as supplemented by a prospectus supplement dated May 1, 2017.

Indenture and Notes

The Notes are governed by the Indenture, dated as of November 25, 2013 (the “Base Indenture”) between the Company and The Bank of New York Mellon Trust Company N.A., as trustee (the “Trustee”), as supplemented by the second supplemental indenture, dated as of May 5, 2017, between the Company and the Trustee (the “Supplemental Indenture” and, together with the Base Indenture, the “Indenture”).

The Notes pay interest semi-annually on May 1 and November 1, commencing on November 1, 2017, at a rate of 4.375% per year, and mature on May 5, 2022, unless earlier converted or purchased by the Company. The Notes are the Company’s senior unsecured obligations that rank equally in right of payment with all of the Company’s existing and future unsecured and unsubordinated indebtedness, including the Company’s 5.25% Convertible Senior Notes due 2018, senior in right of payment to any of the Company’s future indebtedness that is expressly subordinated in right of payment to the Notes, effectively junior to any of the Company’s existing and future secured indebtedness to the extent of the value of the assets securing such indebtedness, and structurally subordinated to all existing and future indebtedness (including trade payables) and preferred equity of the Company’s subsidiaries as well as any of the Company’s existing or future indebtedness that may be guaranteed by any of its subsidiaries (to the extent of any such guarantee).

At any time prior to 5:00 p.m., New York City time, on the business day immediately preceding February 1, 2022, the Notes will be convertible at the option of the holder only upon the specified events and during the specified periods set forth in the following paragraph. Thereafter, the Notes will be convertible at the option of the holder at any time until 5:00 p.m., New York City time, on the second scheduled trading day immediately preceding the maturity date. The Notes will initially be convertible at a conversion rate of 28.0324 shares of the Company’s class A common stock per $1,000 principal amount of Notes, which is equivalent to an initial conversion price of approximately $35.67 per share of class A common stock. The conversion rate is subject to adjustment upon certain events. Upon conversion, the Company’s conversion obligation will be satisfied in cash, shares of class A common stock or a combination thereof (subject to the Company’s right to deliver cash in lieu of all or a portion of such shares, based upon a Daily Conversion Value (as defined in the Indenture) calculated for each VWAP Trading Day (as defined in the Indenture) in the applicable 25 VWAP Trading Day Observation Period (as defined in the Indenture)).

Prior to 5:00 p.m., New York City time, on the business day immediately preceding February 1, 2022, the Notes will be convertible at the option of the holder only under the following circumstances:

(i) during any calendar quarter commencing after June 30, 2017 (and only during such calendar quarter), if the last reported sale price of the Company’s class A common stock for at least 20 trading days (whether or not consecutive) during the period of 30 consecutive trading days ending on the last trading day of the immediately preceding calendar quarter is greater than or equal to 110% of the applicable conversion price on each applicable trading day;

(ii) during the five consecutive business day period after any five consecutive trading day period, or the measurement period, in which the Trading Price (as defined in the Indenture) per $1,000 principal amount of notes for each trading day of such measurement period was less than 98% of the product of the last reported sale price of the Company’s class A common stock and the applicable conversion rate on each such trading day; or

(iii) upon the occurrence of specified corporate events.

Upon a Fundamental Change (as defined in the Indenture), holders may require the Company to purchase the Notes in whole or in part for cash at a price equal to 100% of the principal amount of the Notes to be purchased, plus any accrued and unpaid interest to, but not including, the fundamental change purchase date. In addition, upon a Make-Whole Fundamental Change (as defined in the Indenture), the Company will, under certain circumstances, increase the applicable conversion rate for a holder that elects to convert its Notes in connection with such Make-Whole Fundamental Change.

The Indenture provides that the following are events of default under the Indenture: (a) failure to pay the principal of any Note (including the fundamental change purchase price) when due and payable on the maturity date, upon required repurchase, upon declaration of acceleration or otherwise; (b) failure to pay interest when due and such failure continues for 30 days; (c) failure to observe or perform any other covenant contained in the Notes or the Indenture and such failure continues for 60 days after the Company receives written notice from the Trustee or holders of at least 25% of the aggregate principal amount of the Notes; (d) failure by the Company to comply with its obligation to convert the Notes into the amount of cash or the combination of cash and shares of class A common stock, if any, in accordance with the Indenture upon exercise of a holder’s conversion right and that failure continues for five business days; (e) failure by the Company to comply with its obligations regarding a consolidation, merger or sale; (f) failure by the Company to issue certain notices when due; (g) failure by the Company to pay beyond any applicable grace period, or the acceleration of indebtedness of the Company or any of its subsidiaries in an aggregate amount greater than $50.0 million (or its foreign currency equivalent at the time); and (h) certain events of bankruptcy, insolvency or reorganization involving the Company.

If certain bankruptcy and insolvency-related events of defaults with respect to the Company occur, the principal of, and accrued and unpaid interest on, all of the then outstanding Notes will automatically become due and payable. If an event of default other than certain bankruptcy and insolvency-related events of defaults with respect to the Company occurs and is continuing, the Trustee by notice to the Company or the holders of the Notes of at least 25% in principal amount of the outstanding Notes by notice to the Company and the Trustee, may declare the principal of, and accrued and unpaid interest on, all of the then outstanding Notes to be due and payable. Notwithstanding the foregoing, the Indenture provides that, to the extent the Company elects, the sole remedy for an event of default relating to certain failures by the Company to comply with reporting covenants in the Indenture consists exclusively of the right to receive additional interest on the Notes.

The foregoing summary description of the material terms of the Base Indenture and the Supplemental Indenture is qualified in its entirety by reference to the Base Indenture, a copy of which has been filed as Exhibit 4.1 to the Company’s Current Report on Form 8-K (File No. 001-14788) filed with the Securities and Exchange Commission (the “Commission”) on November 25, 2013, and the Supplemental Indenture, a copy of which is attached hereto as Exhibit 4.2 (which includes the form of 4.375% Convertible Senior Notes due 2022 filed as Exhibit 4.3), each of which is incorporated herein by reference.

Ladies and Gentlemen:

Blackstone Mortgage Trust, Inc., a corporation organized under the laws of the State of Maryland (the “Company”), proposes to sell to the several underwriters named in Schedule II hereto (the “Underwriters”), for whom you (the “Representatives”) are acting as representatives, $250,000,000 principal amount of its 4.375% Convertible Senior Notes due 2022 (the “Underwritten Securities”), convertible into cash, shares of the Company’s class A common stock, par value $0.01 per share (the “Common Stock”), or a combination of cash and shares of Common Stock at the Company’s election (any such shares issuable upon conversion, including the maximum number of shares that may be added to the conversion rate in connection with a make-whole fundamental change, the “Underlying Shares”). The Company also proposes to grant to the Underwriters an option to purchase up to an additional $37,500,000 aggregate principal amount of its 4.375% Convertible Senior Notes due 2022 (the “Option Securities” and, together with the Underwritten Securities, the “Securities”) solely to cover over-allotments, if any. The Securities are to be issued under an indenture (the “Base Indenture”), dated as of November 25, 2013, between the Company and The Bank of New York Mellon Trust Company, N.A., as trustee (the “Trustee”), as supplemented by the Second Supplemental Indenture, to be dated May 5, 2017, between the Company and the Trustee (the “Second Supplemental Indenture” and together with the Base Indenture, the “Indenture”).

Any reference herein to the Registration Statement, the Base Prospectus, any Preliminary Prospectus or the Final Prospectus shall be deemed to refer to and include the documents incorporated by reference therein pursuant to Item 12 of Form S-3 which were filed under the Exchange Act on or before the Effective Date of the Registration Statement or the

issue date of the Base Prospectus, any Preliminary Prospectus or the Final Prospectus, as the case may be; and any reference herein to the terms “amend,” “amendment” or “supplement” with respect to the Registration Statement, the Base Prospectus, any Preliminary Prospectus or the Final Prospectus shall be deemed to refer to and include the filing of any document under the Exchange Act after the Effective Date of the Registration Statement or the issue date of the Base Prospectus, any Preliminary Prospectus or the Final Prospectus, as the case may be, deemed to be incorporated therein by reference. Certain terms used herein are defined in Section 20 hereof.

1. Representations and Warranties.

(i) The Company represents and warrants to each Underwriter and agrees with each Underwriter as set forth below in this Section 1(i).

(a) The Company meets the requirements for use of Form S-3 under the Act and has prepared and filed with the Commission an automatic shelf registration statement, as defined in Rule 405, on Form S-3 (File No. 333-212769), including a related Base Prospectus, for registration under the Act of the offering and sale of the Securities and the Underlying Shares. Such Registration Statement, including any amendments thereto filed prior to the Execution Time, became effective upon filing. The Company may have filed with the Commission, as part of an amendment to the Registration Statement or pursuant to Rule 424(b), one or more Preliminary Prospectuses relating to the Securities, each of which has previously been furnished to you. The Company will file with the Commission a Final Prospectus relating to the Securities in accordance with Rule 424(b). As filed, such Final Prospectus shall contain all information required by the Act and, except to the extent the Representatives shall agree in writing to a modification, shall be in all substantive respects in the form furnished to you prior to the Execution Time or, to the extent not completed at the Execution Time, shall contain only such specific additional information and other changes (beyond that contained in the Base Prospectus and any Preliminary Prospectus) as the Company has advised you, prior to the Execution Time, will be included or made therein. The Registration Statement, at the Execution Time, meets the requirements set forth in Rule 415(a)(1)(x). The initial Effective Date of the Registration Statement was not earlier than the date three years before the Execution Time.

(b) On each Effective Date, the Registration Statement did, and when the Final Prospectus is first filed in accordance with Rule 424(b) and on the Closing Date (as defined herein) and on any date on which Option Securities are purchased, if such date is not the Closing Date (a “settlement date”), the Final Prospectus (and any supplements thereto) will, comply in all material respects with the applicable requirements of the Act, the Exchange Act and the Trust Indenture Act; on each Effective Date and at the Execution Time, the Registration Statement did not and will not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein not misleading; and on the date of any filing pursuant to Rule 424(b) and on the Closing Date and any settlement date, the Final Prospectus (together with any supplements thereto) will not include any untrue statement of a material fact or omit to state a material fact necessary in order to make the

2

statements therein, in the light of the circumstances under which they were made, not misleading; provided, however, that the Company makes no representations or warranties as to the information contained in or omitted from the Registration Statement or the Final Prospectus (or any supplement thereto) in reliance upon and in conformity with information furnished in writing to the Company by or on behalf of any Underwriter through the Representatives specifically for inclusion in the Registration Statement or the Final Prospectus (or any supplement thereto), it being understood and agreed that the only such information furnished by or on behalf of any Underwriter consists of the information described as such in Section 8(b) hereof. No stop order suspending the effectiveness of the Registration Statement or any part thereof has been issued and, to the knowledge of the Company, no proceeding for that purpose has been instituted or threatened by the Commission or by the state securities authority of any jurisdiction. No order preventing or suspending the use of the Final Prospectus has been issued and, to the knowledge of the Company, no proceeding for that purpose has been instituted by the Commission or by the state securities authority of any jurisdiction.

(c) (i) The Disclosure Package and (ii) each electronic road show when taken together as a whole with the Disclosure Package, as of the Execution Time, does not contain any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. The preceding sentence does not apply to statements in or omissions from the Disclosure Package based upon and in conformity with written information furnished to the Company by any Underwriter through the Representatives specifically for use therein, it being understood and agreed that the only such information furnished by or on behalf of any Underwriter consists of the information described as such in Section 8(b) hereof.

(d) (i) At the time of filing the Registration Statement, (ii) at the time of the most recent amendment thereto for the purposes of complying with Section 10(a)(3) of the Act (whether such amendment was by post-effective amendment, incorporated report filed pursuant to Sections 13 or 15(d) of the Exchange Act or form of prospectus) and (iii) at the time the Company or any person acting on its behalf (within the meaning, for this clause only, of Rule 163(c)) made any offer relating to the Securities in reliance on the exemption in Rule 163, the Company was or is (as the case may be) a “well-known seasoned issuer” as defined in Rule 405. The Company agrees to pay the fees required by the Commission relating to the Securities within the time required by Rule 456(b)(1) without regard to the proviso therein and otherwise in accordance with Rules 456(b) and 457(r).

(e) (i) At the earliest time after the filing of the Registration Statement that the Company or another offering participant made a bona fide offer (within the meaning of Rule 164(h)(2)) of the Act and (ii) as of the Execution Time (with such date being used as the determination date for purposes of this clause (ii)), the Company was not and is not an Ineligible Issuer (as defined in Rule 405), without taking account of any determination by the Commission pursuant to Rule 405 that it is not necessary that the Company be considered an Ineligible Issuer.

3

(f) Each Issuer Free Writing Prospectus and the final term sheet prepared and filed pursuant to Section 5(i)(b) hereto does not include any information that conflicts with the information contained in the Registration Statement, the Final Prospectus, and any preliminary or other prospectus deemed to be a part thereof that has not been superseded or modified. The foregoing sentence does not apply to statements in or omissions from any Issuer Free Writing Prospectus based upon and in conformity with written information furnished to the Company by any Underwriter through the Representatives specifically for use therein, it being understood and agreed that the only such information furnished by or on behalf of any Underwriter consists of the information described as such in Section 8(b) hereof.

(g) The copies of each Preliminary Prospectus, each Issuer Free Writing Prospectus that is required to be filed with the Commission pursuant to Rule 433 and the Final Prospectus and any amendments or supplements to any of the foregoing, that have been delivered to the Underwriters in connection with the offering of the Securities (whether to meet the request of purchasers pursuant to Rule 173(d) or otherwise) were identical to the electronically transmitted copies thereof filed with the Commission pursuant to EDGAR, except to the extent permitted by Regulation S-T. For purposes of this Underwriting Agreement (the “Agreement”), references to the “delivery” or “furnishing” of any of the foregoing documents to the Underwriters, and any similar terms, include, without limitation, electronic delivery.

4

If the sale of the Securities provided for herein is not consummated because any condition to the obligations of the Underwriters set forth in Section 6 hereof is not satisfied, because of any termination pursuant to Section 10 hereof or because of any refusal, inability or failure on the part of the Company or the Manager to perform any agreement herein or comply with any provision hereof other than by reason of a default by any of the Underwriters, the Company will reimburse the Underwriters severally through the Representatives on demand for all documented out-of-pocket expenses (including reasonable fees and disbursements of counsel) that shall have been incurred by them in connection with the proposed purchase and sale of the Securities.

8. Indemnification and Contribution.

(a) The Company agrees to indemnify and hold harmless each Underwriter, the directors, officers, employees, affiliates and agents of each Underwriter and each person who controls any Underwriter within the meaning of either the Act or the Exchange Act against any and all losses, claims, damages or liabilities, joint or several, to which they or any of them may become subject under the Act, the Exchange Act or other Federal or state statutory law or regulation, at common law or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement as originally filed or in any amendment thereof, or in the Base Prospectus, any Preliminary Prospectus or any other preliminary prospectus supplement relating to the Securities, the Disclosure Package, the Final Prospectus, or any Issuer Free Writing Prospectus, or in any amendment or supplement to any of the foregoing, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and agrees to reimburse each such indemnified party, as incurred, for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that the Company will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon any such untrue statement or alleged untrue statement or omission or alleged omission made therein in reliance upon and in conformity with written information furnished to the Company by or on behalf of any Underwriter through the Representatives specifically for inclusion therein. This indemnity agreement will be in addition to any liability which the Company may otherwise have.

30

(b) Each Underwriter severally and not jointly agrees to indemnify and hold harmless the Company, its directors, each of the Company’s officers who signed the Registration Statement, and each person who controls the Company within the meaning of either the Act or the Exchange Act, to the same extent as the foregoing indemnity from the Company to each Underwriter, but only with reference to written information relating to such Underwriter furnished to the Company by or on behalf of such Underwriter through the Representatives specifically for inclusion in the documents referred to in the foregoing indemnity. This indemnity agreement will be in addition to any liability which any Underwriter may otherwise have. The Company acknowledges that the following statements set forth in the Preliminary Prospectus and the Final Prospectus under the heading “Underwriting”: (i) the names of the Underwriters and their respective participation in the sale of the Securities, (ii) the third paragraph thereof related to selling concessions and dealer reallowances, (iii) the twelfth paragraph thereof, and (iv) the thirteenth and fourteenth paragraphs (including, for the avoidance of doubt, information in bullet points) thereof related to stabilization, short positions and covering transactions and penalty bids, constitute the only information furnished in writing by or on behalf of the several Underwriters for inclusion in any Preliminary Prospectus, the Final Prospectus or any Issuer Free Writing Prospectus.

(c) Promptly after receipt by an indemnified party under this Section 8 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this Section 8, notify the indemnifying party in writing of the commencement thereof; but the failure so to notify the indemnifying party (i) will not relieve it from liability under paragraph (a) or (b) above unless and to the extent it did not otherwise learn of such action and such failure results in the forfeiture by the indemnifying party of substantial rights and defenses and (ii) will not, in any event, relieve the indemnifying party from any obligations to any indemnified party other than the indemnification obligation provided in paragraph (a) or (b) above. The indemnifying party shall be entitled to appoint counsel of the indemnifying party’s choice at the indemnifying party’s expense to represent the indemnified party in any action for which indemnification is sought (in which case the indemnifying party shall not thereafter be responsible for the fees and expenses of any separate counsel retained by the indemnified party or parties except as set forth below); provided, however, that such counsel shall be reasonably satisfactory to the indemnified party. Notwithstanding the indemnifying party’s election to appoint counsel to represent the indemnified party in an action, the indemnified party shall have the right to employ separate counsel (including local counsel), and the indemnifying party shall bear the reasonable fees, costs and expenses of such separate counsel if (i) the use of counsel chosen by the indemnifying party to represent the indemnified party would present such counsel with a conflict of interest, (ii) the actual or potential defendants in, or targets of, any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that there may be legal defenses available to it and/or other indemnified parties which are different from or additional to those available to the indemnifying party, (iii) the indemnifying party shall not have employed counsel reasonably satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of the institution of such action or (iv) the indemnifying party shall authorize the indemnified party to employ separate counsel at the expense of the indemnifying party. It is understood and agreed that the

31

indemnifying party shall not, in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the fees and expenses of more than one separate firm (in addition to any local counsel) for all indemnified parties. The indemnifying party shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify each indemnified party from and against any loss or liability by reason of such settlement or judgment. If at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel, such indemnifying party agrees that it shall be liable for any settlement of the nature contemplated by the previous sentence effected without its written consent if (i) such settlement is entered into more than 45 days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party shall have received notice of the terms of such settlement at least 30 days prior to such settlement being entered into and (iii) such indemnifying party shall not have reimbursed such indemnified party in accordance with such request prior to the date of such settlement unless such failure to reimburse the indemnified party is based on a dispute with a good faith basis as to either the obligation of the indemnifying party arising under this Section 8 to indemnify the indemnified party or the amount of such obligation and the indemnifying party shall have notified the indemnified party of such good faith dispute prior to the date of such settlement. An indemnifying party will not, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent (A) includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding and (B) does not include a statement as to, or an admission of, fault, culpability or a failure to act by or on behalf of an indemnified party.

(d) In the event that the indemnity provided in paragraph (a) or (b) of this Section 8 is unavailable to or insufficient to hold harmless an indemnified party for any reason, the Company and the Underwriters severally agree to contribute to the aggregate losses, claims, damages and liabilities (including legal or other expenses reasonably incurred in connection with investigating or defending the same) (collectively “Losses”) to which the Company and one or more of the Underwriters may be subject in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and by the Underwriters on the other from the offering of the Securities; provided, however, that in no case shall any Underwriter (except as may be provided in any agreement among underwriters relating to the offering of the Securities) be responsible for any amount in excess of the underwriting discount or commission applicable to the Securities purchased by such Underwriter hereunder. If the allocation provided by the immediately preceding sentence is unavailable for any reason, the Company and the Underwriters severally shall contribute in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Company on the one hand and of the Underwriters on the other in connection with the statements or omissions which resulted in such Losses as well as any other relevant

32

equitable considerations. Benefits received by the Company shall be deemed to be equal to the total net proceeds from the offering (before deducting expenses) received by the Company, and benefits received by the Underwriters shall be deemed to be equal to the total underwriting discounts and commissions, in each case as set forth on the cover page of the Final Prospectus. Relative fault shall be determined by reference to, among other things, whether any untrue or any alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information provided by the Company on the one hand or by the Underwriters on the other, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The Company and the Underwriters agree that it would not be just and equitable if contribution were determined by pro rata allocation or any other method of allocation which does not take account of the equitable considerations referred to above. Notwithstanding the provisions of this paragraph (d), no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this Section 8, each person who controls an Underwriter within the meaning of either the Act or the Exchange Act and each director, officer, employee, affiliate and agent of an Underwriter shall have the same rights to contribution as such Underwriter, and each person who controls the Company within the meaning of either the Act or the Exchange Act, each officer of the Company who shall have signed the Registration Statement and each director of the Company shall have the same rights to contribution as the Company, subject in each case to the applicable terms and conditions of this paragraph (d).

9. Default by an Underwriter. If any one or more Underwriters shall fail to purchase and pay for any of the Securities agreed to be purchased by such Underwriter or Underwriters hereunder and such failure to purchase shall constitute a default in the performance of its or their obligations under this Agreement, the remaining Underwriters shall be obligated severally to take up and pay for (in the respective proportions which the principal amount of Securities set forth opposite their names in Schedule II hereto bears to the aggregate principal amount of Securities set forth opposite the names of all the remaining Underwriters) the Securities which the defaulting Underwriter or Underwriters agreed but failed to purchase; provided, however, that in the event that the aggregate principal amount of Securities which the defaulting Underwriter or Underwriters agreed but failed to purchase shall exceed 10% of the aggregate principal amount of Securities set forth in Schedule II hereto, the remaining Underwriters shall have the right to purchase all, but shall not be under any obligation to purchase any, of the Securities, and if such nondefaulting Underwriters do not purchase all the Securities, this Agreement will terminate without liability to any nondefaulting Underwriter or the Company. In the event of a default by any Underwriter as set forth in this Section 9, the Closing Date shall be postponed for such period, not exceeding five Business Days, as the Representatives shall determine in order that the required changes in the Registration Statement and the Final Prospectus or in any other documents or arrangements may be effected. Nothing contained in this Agreement shall relieve any defaulting Underwriter of its liability, if any, to the Company and any nondefaulting Underwriter for damages occasioned by its default hereunder.

33

10. Termination. This Agreement shall be subject to termination in the absolute discretion of the Representatives, by notice given to the Company prior to delivery of and payment for the Securities, if at any time prior to such time (i) trading in the Common Stock shall have been suspended by the Commission or the NYSE or trading in securities generally on the NYSE shall have been suspended or limited or minimum prices shall have been established on such exchange, (ii) a banking moratorium shall have been declared either by Federal or New York State authorities or (iii) there shall have occurred any outbreak or escalation of hostilities, declaration by the United States of a national emergency or war, or other calamity or crisis the effect of which on financial markets is such as to make it, in the sole judgment of the Representatives, impractical or inadvisable to proceed with the offering or delivery of the Securities as contemplated by the Disclosure Package or the Final Prospectus (exclusive of any supplement thereto).

11. Representations and Indemnities to Survive. The respective agreements, representations, warranties, indemnities, rights of contribution and other statements of the Company, the Manager or the officers of the Company or the Manager, and of the Underwriters set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation made by or on behalf of any Underwriter, the Company, the Manager or any of the officers, directors, employees, agents, affiliates or controlling persons referred to in Section 8 hereof, and will survive delivery of and payment for the Securities. The provisions of Sections 7 and 8 hereof shall survive the termination or cancellation of this Agreement.

12. Notices. All communications hereunder will be in writing and effective only on receipt, and, if sent to the Representatives, will be mailed, delivered or telefaxed to (i) Citigroup Global Markets Inc.

Keller and Edgar J. Lewandowski.

13. Compliance with USA Patriot Act. In accordance with the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)), the Underwriters are required to obtain, verify and record information that identifies their respective clients, including the Company, which information may include the name and address of their respective clients, as well as other information that will allow the Underwriters to properly identify their respective clients.

34

14. Successors.

15. No Fiduciary Duty. Each of the Company and the Manager hereby acknowledges and agrees that (a) the purchase and sale of the Securities pursuant to this Agreement is an arm’s-length commercial transaction between the Company and the Manager on the one hand, and the Underwriters and any affiliate through which they may be acting, on the other, (b) the Underwriters are acting as principal and not as an agent or fiduciary of the Company or the Manager and (c) the engagement of the Underwriters by the Company in connection with the offering and the process leading up to the offering is as independent contractors and not in any other capacity. Furthermore, each of the Company and the Manager agrees that it is solely responsible for making its own judgments in connection with the offering (irrespective of whether any of the Underwriters has advised or is currently advising the Company or the Manager on related or other matters). Each of the Company and the Manager agrees that it will not claim that the Underwriters have rendered advisory services of any nature or respect, or owe an agency, fiduciary or similar duty to the Company or the Manager, in connection with such transaction or the process leading thereto.

16. Integration. This Agreement supersedes all prior agreements and understandings (whether written or oral) by and among the Company, the Manager and the Underwriters, or any of them, with respect to the subject matter hereof.

17. Applicable Law. This Agreement and any claim, controversy or dispute arising under or related to this Agreement will be governed by and construed in accordance with the laws of the State of New York applicable to contracts made and to be performed within the State of New York.

18. Waiver of Jury Trial. Each of the Company and the Manager hereby irrevocably waives, to the fullest extent permitted by applicable law, any and all right to trial by jury in any legal proceeding arising out of or relating to this Agreement or the transactions contemplated hereby.

The exact stock prices and effective dates may not be set forth in the table above, in which case:

• if the stock price is between two stock prices in the table or the effective date is between two effective dates in the table, the number of additional shares will be determined by a straight-line interpolation between the number of additional shares set forth for the higher and lower stock prices and the earlier and later effective dates, as applicable, based on a 365-day year;

• if the stock price is greater than $42.50 per share (subject to adjustment in the same manner as the stock prices set forth in the column headings of the table above), no additional shares will be added to the conversion rate; or

• if the stock price is less than $31.02 per share (subject to adjustment in the same manner as the stock prices set forth in the column headings of the table above), no additional shares will be added to the conversion rate.

Notwithstanding the foregoing, in no event will the conversion rate be increased on account of a make-whole fundamental change to exceed 32.2373 shares of our class A common stock per $1,000 principal amount of Notes, subject to adjustments in the same manner as the conversion rate is required to be adjusted as set forth under “Description of the Notes—Conversion Rights—Conversion Rate Adjustments” in the Preliminary Prospectus Supplement.

(1) if the Securities to be purchased are Physical Securities, delivery to the Paying Agent by the Holder of a duly completed notice (the “Fundamental Change Purchase Notice”) in the form set forth in Attachment 2 to the Form of Security attached hereto as Exhibit A and of the Securities, duly endorsed for transfer, on or before the Close of Business on the Business Day immediately preceding the Fundamental Change Purchase Date, subject to extensions to comply with applicable law (the “Fundamental Change Expiration Time”); and

(2) if the Securities to be purchased are Global Securities, delivery of the Securities, by book-entry transfer, in compliance with the Applicable Procedures of the Depositary and the satisfaction of any other requirements of the Depositary in connection with tendering beneficial interests in a Global Security for purchase, by the Fundamental Change Expiration Time.

12

The Fundamental Change Purchase Notice in respect of any Securities to be purchased shall state:

(1) if certificated, the certificate numbers of such Securities;

(2) the portion of the principal amount of such Securities, which must be such that the principal amount that is not to be purchased of each Security that is not to be purchased in full equals $1,000 or an integral multiple of $1,000 in excess thereof; and

(3) that such Securities are to be purchased by the Company pursuant to the applicable provisions of the Securities and this Indenture.

Notwithstanding anything herein to the contrary, any Holder delivering to the Paying Agent the Fundamental Change Purchase Notice contemplated by this Section 3.02 shall have the right to withdraw, in whole or in part, such Fundamental Change Purchase Notice at any time prior to the Fundamental Change Expiration Time by delivery of a written notice of withdrawal to the Paying Agent in accordance with Section 3.04.

The Paying Agent shall promptly notify the Company of the receipt by it of any Fundamental Change Purchase Notice or written notice of withdrawal thereof.

(b) On or before the 20th calendar day after the occurrence of a Fundamental Change, the Company shall provide to all Holders of the Securities, the Trustee and the Paying Agent (in the case of any Paying Agent other than the Trustee) a notice (the “Fundamental Change Company Notice”) of the occurrence of such Fundamental Change and of the purchase right at the option of the Holders arising as a result thereof. Such notice shall be sent by first class mail or, in the case of any Global Securities, in accordance with the procedures of the Depositary for providing notices. Simultaneously with providing such Fundamental Change Company Notice, the Company shall publish this information in a newspaper of general circulation in The City of New York or publish the information on the Company’s website or through such other public medium as the Company may use at that time.

Each Fundamental Change Company Notice shall specify:

(1) the events causing the Fundamental Change;

(2) the date of the Fundamental Change;

(3) the last date on which a Holder of Securities may exercise the purchase right pursuant to this Article 3;

(4) the Fundamental Change Purchase Price;

(5) the Fundamental Change Purchase Date;

(6) the name and address of the Paying Agent and the Conversion Agent, if applicable;

(7) if applicable, the applicable Conversion Rate and any adjustments to the applicable Conversion Rate;

(8) if applicable, that the Securities with respect to which a Fundamental Change Purchase Notice has been delivered by a Holder may be converted only if the Holder withdraws the Fundamental Change Purchase Notice in accordance with the terms of this Indenture; and

(9) the procedures that Holders must follow to require the Company to purchase their Securities.

13

No failure of the Company to give the foregoing notices and no defect therein shall limit the purchase rights of the Holders of Securities or affect the validity of the proceedings for the purchase of the Securities pursuant to this Section 3.02.

(c) Notwithstanding the foregoing, there shall be no purchase of any Securities pursuant to this Section 3.02 if the principal amount of the Securities has been accelerated, and such acceleration has not been rescinded, on or prior to the Fundamental Change Purchase Date (except in the case of an acceleration resulting from a Default by the Company in the payment of the Fundamental Change Purchase Price with respect to such Securities). The Paying Agent will promptly return to the respective Holders thereof any Physical Securities held by it during the acceleration of the Securities (except in the case of an acceleration resulting from a Default by the Company in the payment of the Fundamental Change Purchase Price with respect to such Securities) and shall deem to be cancelled any instructions for book-entry transfer of the Securities in compliance with the procedures of the Depositary, in which case, upon such return or cancellation, as the case may be, the Fundamental Change Purchase Notice with respect thereto shall be deemed to have been withdrawn.

Section 3.03 Effect of Fundamental Change Purchase Notice. Upon receipt by the Paying Agent of a Fundamental Change Purchase Notice specified in Section 3.02, the Holder of the Security in respect of which such Fundamental Change Purchase Notice was given shall (unless such Fundamental Change Purchase Notice is withdrawn in accordance with Section 3.04) thereafter be entitled to receive solely the Fundamental Change Purchase Price in cash with respect to such Security (and any previously accrued and unpaid interest on such Security). Such Fundamental Change Purchase Price shall be paid to such Holder, subject to receipt of funds by the Paying Agent, on the later of (x) the applicable Fundamental Change Purchase Date (provided the conditions in Section 3.02 have been satisfied) and (y) the time of delivery or book-entry transfer of such Security to the Paying Agent by the Holder thereof in the manner required by Section 3.02, subject in each case to extensions to comply with applicable law.

Section 3.04 Withdrawal of Fundamental Change Purchase Notice. A Fundamental Change Purchase Notice may be withdrawn (in whole or in part) by means of a written notice of withdrawal delivered to the Paying Agent in accordance with the Fundamental Change Company Notice at any time prior to the Fundamental Change Expiration Time, specifying:

(1) the principal amount of the Securities with respect to which such notice of withdrawal is being submitted;

(2) if Physical Securities have been issued, the certificate numbers of the withdrawn Securities; and

(3) the principal amount, if any, of each Security that remains subject to the Fundamental Change Purchase Notice, which must be such that the principal amount not to be purchased equals $1,000 or an integral multiple of $1,000 in excess thereof;

provided, however, that if the Securities are Global Securities, the notice must comply with Applicable Procedures of the Depositary.

The Paying Agent will promptly return to the respective Holders thereof any Physical Securities with respect to which a Fundamental Change Purchase Notice has been withdrawn in compliance with the provisions of this Section 3.04.

Section 3.05 Deposit of Fundamental Change Purchase Price. Prior to 10:00 a.m., New York City time, on the Fundamental Change Purchase Date, the Company shall deposit with the Paying Agent (or, if the Company or a Subsidiary or an Affiliate of either of them is acting as the Paying Agent, shall segregate and hold in trust as provided herein) an amount of money (in immediately available funds if deposited on such Business Day) sufficient to pay the Fundamental Change Purchase Price of all the Securities or portions thereof that are to be purchased as of the Fundamental Change Purchase Date. If the Paying Agent holds cash sufficient to pay the Fundamental Change Purchase Price of the Securities for which a Fundamental Change Purchase Notice has been tendered and not withdrawn in accordance with this Indenture on the Fundamental Change Purchase Date, then as of such Fundamental Change Purchase Date, (a) such Securities will cease to be Outstanding and interest will cease to accrue thereon (whether or not book-entry transfer of such Securities is made or such Securities have been delivered to the Paying Agent) and (b) all other rights of the Holders in respect thereof will terminate (other than the right to receive the Fundamental Change Purchase Price and previously accrued and unpaid interest upon delivery or book-entry transfer of such Securities).

Section 3.06 Securities Purchased in Whole or in Part. Any Security that is to be purchased, whether in whole or in part, shall be surrendered at the office of the Paying Agent (with, if the Company or the Trustee so requires in the case of Physical

14

Securities, due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Trustee duly executed by, the Holder thereof or such Holder’s attorney duly authorized in writing) and the Company shall execute and the Trustee shall authenticate and deliver to the Holder of such Security, without service charge, a new Security or Securities, of any authorized denomination as requested by such Holder in aggregate principal amount equal to, and in exchange for, the portion of the principal amount of the Security so surrendered that is not purchased. Any Holder whose Securities are purchased pursuant to this Article 3 shall receive payment of the Fundamental Change Purchase Price on the later of (i) the Fundamental Change Purchase Date or (ii) the time of book-entry transfer or the delivery of the Securities so purchased.

Section 3.07 Covenant To Comply with Applicable Laws upon Purchase of Securities. In connection with any offer to purchase Securities under Section 3.02, the Company shall, in each case if required by law, (i) comply with Rule 13e-4, Rule 14e-1 and any other tender offer rules under the Exchange Act that may then be applicable, (ii) file a Schedule TO or any other required schedule under the Exchange Act and (iii) otherwise comply with any other U.S. federal or state securities laws applicable to the Company in connection with such purchase offer, in each case, so as to permit the rights and obligations under Section 3.02 to be exercised in the time and in the manner specified in Section 3.02.

Section 3.08 Repayment to the Company. To the extent that the aggregate amount of cash deposited by the Company pursuant to Section 3.05 exceeds the aggregate Fundamental Change Purchase Price of the Securities or portions thereof that the Company is obligated to purchase as of the Fundamental Change Purchase Date, then, following the Fundamental Change Purchase Date, the Paying Agent shall promptly return any such excess to the Company.

ARTICLE 4

CONVERSION

Section 4.01 Right To Convert. (a) Subject to and upon compliance with the provisions of the Indenture, each Holder shall have the right, at such Holder’s option, to convert its Securities, or any portion of its Securities such that the principal amount that remains Outstanding of each Security that is not converted in full equals $1,000 or an integral multiple of $1,000 in excess thereof, into the Settlement Amount determined in accordance with Section 4.03(a) hereof, (x) prior to the Close of Business on the Business Day immediately preceding February 1, 2022, only upon satisfaction of one or more of the conditions described in Section 4.01(b) hereof, and (y) on or after February 1, 2022, at any time prior to the Close of Business on the second Scheduled Trading Day immediately preceding the Maturity Date.

(b) (1) A Holder may surrender Securities for conversion during any calendar quarter commencing after June 30, 2017 (and only during such calendar quarter) if the Last Reported Sale Price of the Common Stock for at least 20 Trading Days (whether or not consecutive) during the period of 30 consecutive Trading Days ending on the last Trading Day of the immediately preceding calendar quarter is greater than or equal to 110% of the Conversion Price in effect on each applicable Trading Day.

(2) A Holder may surrender all or a portion of its Securities for conversion during the five Business Day period after any five consecutive Trading Day period (the “Measurement Period”) in which the Trading Price per $1,000 principal amount of Securities, as determined following a request by a Holder in accordance with the procedures set forth in this Section 4.01(b)(2), for each Trading Day of such Measurement Period was less than 98% of the product of (i) the Last Reported Sale Price of the Common Stock on such Trading Day and (ii) the Conversion Rate in effect on such Trading Day. The Trading Price shall be determined by the Bid Solicitation Agent pursuant to this Section 4.01(b)(2) and the definition of “Trading Price” set forth in Section 1.02 hereof. The Company shall provide written notice to the Bid Solicitation Agent (if other than the Company) of the three independent nationally recognized securities dealers selected by the Company in accordance with the definition of Trading Price, along with the appropriate contact information for each. The Bid Solicitation Agent (if other than the Company) shall have no obligation to determine the Trading Price of the Securities unless the Company has requested such determination; and the Company shall have no obligation to make such request (or, if the Company is the Bid Solicitation Agent, the Company shall have no obligation to determine the Trading Price of the Securities) unless a Holder of a Security provides it with reasonable evidence that the Trading Price per $1,000 principal amount of Securities would be less than 98% of the product of (i) the Last Reported Sale Price of the Common Stock on such Trading Day and (ii) the Conversion Rate in effect on such Trading Day. At such time, the Company shall instruct the Bid Solicitation Agent (if other than the Company) to determine (or, if the Company is the Bid Solicitation Agent, the Company shall determine) the Trading Price per $1,000 principal amount of the Securities beginning on the next Trading Day and on each successive Trading Day until the

15

Trading Price per $1,000 principal amount of Securities for a Trading Day is greater than or equal to 98% of the product of (i) the Last Reported Sale Price of the Common Stock on such Trading Day and (ii) the Conversion Rate in effect on such Trading Day. Whenever the condition to conversion set forth in this Section 4.01(b)(2) has been met, but was not met on the immediately preceding Trading Day, the Company will so notify the Holders and the Trustee. If, at any time after the condition to conversion set forth in this Section 4.01(b)(2) has been met, the condition to conversion set forth in this Section 4.01(b)(2) ceases to be met, the Company will so notify the Holders and the Trustee on the first Trading Day on which such condition ceases to be met.

(3) If the Company elects to (x) issue to all or substantially all holders of the Common Stock rights, options or warrants entitling them for a period of not more than 45 calendar days after the date of such issuance to subscribe for or purchase shares of the Common Stock, at a price per share less than the Last Reported Sale Price of the Common Stock on the Trading Day immediately preceding the date of announcement of such issuance (taking into account any consideration received by the Company as described in Section 4.04(b)); or (y) distribute to all or substantially all holders of the Common Stock the Company’s assets, debt securities or rights to purchase the Company’s securities, which distribution (excluding for this purpose a distribution required to avoid the imposition of tax on undistributed income) has a per-share value, as reasonably determined by the Board of Directors, exceeding 10% of the Last Reported Sale Price of the Common Stock on the Trading Day immediately preceding the date of announcement for such distribution, then, the Company must deliver notice of such issuance or distribution, and of the Ex-Dividend Date for such issuance or distribution, to the Holders at least 30 Scheduled Trading Days prior to the Ex-Dividend Date for such issuance or distribution. Holders may surrender their Securities for conversion at any time during the period beginning on the 30th Scheduled Trading Day immediately prior to the Ex-Dividend Date for such issuance or distribution and ending on the earlier of (a) the Close of Business on the Business Day immediately preceding the Ex-Dividend Date for such issuance or distribution or (b) the Company’s announcement that such issuance or distribution will not take place, even if the Securities are not otherwise convertible at such time; provided, however, that Holders may not convert their Securities pursuant to this Section 4.01(b)(3) if the Company provides that Holders shall participate, at the same time and upon the same terms as holders of the Common Stock, and as a result of holding the Securities, in the relevant issuance or distribution without having to convert their Securities as if they held a number of shares of the Common Stock equal to the Conversion Rate in effect on the Ex-Dividend Date for such issuance or distribution multiplied by the principal amount (expressed in thousands) of Securities held by such Holder on the Ex-Dividend Date for such issuance or distribution.

(4) If (i) a Make-Whole Fundamental Change occurs or (ii) the Company is a party to (a) a consolidation, merger, binding share exchange, pursuant to which the Common Stock would be converted into cash, securities or other assets or (b) a sale, conveyance, transfer or lease of all or substantially all of the assets of the Company and its Subsidiaries, on a consolidated basis, to another Person (other than any of the Company’s Subsidiaries), the Securities may be surrendered for conversion at any time from or after the date that is 35 Scheduled Trading Days prior to the anticipated Fundamental Change Effective Date or the anticipated effective date of such sale, conveyance, transfer or lease, as the case may be (or, if later, the Business Day after the Company gives notice of such transaction) until the Close of Business (i) if such transaction is a Fundamental Change, on the Business Day immediately preceding the related Fundamental Change Purchase Date, and, (ii) otherwise, on the 35th Business Day immediately following the effective date for such transaction. The Company will notify the Holders of any such transaction:

(A) as promptly as practicable following the date the Company publicly announces such transaction but in no event less than 35 Scheduled Trading Days prior to the anticipated effective date of such transaction; or

(B) if the Company does not have knowledge of such transaction at least 35 Scheduled Trading Days prior to the anticipated effective date of such transaction, within three Business Days of the date upon which the Company receives notice, or otherwise becomes aware, of such transaction, but in no event later than the actual effective date of such transaction.

(c) Notwithstanding any other provision of the Securities or this Indenture, no Holder of Securities will be entitled to receive Common Stock following conversion of such Securities to the extent that receipt of such Common Stock would cause such Holder to exceed the ownership limitations contained in the Company’s charter.

(d) If any delivery of shares of Common Stock owed to a Holder upon conversion of Securities is not made, in whole or in part, as a result of the limitations described in Section 4.01(c), the Company’s obligation to make such delivery shall not be extinguished and the Company shall deliver such shares as promptly as practicable after any such converting Holder gives notice to the Company that such delivery would not result in it exceeding the ownership limitations in the Company’s charter.

16

Section 4.02 Conversion Procedures.

(a) Each Security shall be convertible at the office of the Conversion Agent and, if applicable, in accordance with the Applicable Procedures of the Depositary.

(b) To exercise the conversion privilege with respect to a beneficial interest in a Global Security, the Holder must complete the appropriate instruction form for conversion pursuant to the Depositary’s book-entry conversion program, furnish appropriate endorsements and transfer documents if required by the Company or the Conversion Agent, and pay the funds, if any, required by Section 4.02(f) and any taxes or duties if required pursuant to Section 4.02(g), and the Conversion Agent must be informed of the conversion in accordance with the customary practice of the Depositary.

To exercise the conversion privilege with respect to any Physical Securities, the Holder of such Physical Securities shall:

(1) complete and manually sign a conversion notice in the form set forth in the Form of Notice of Conversion (the “Conversion Notice”) or a facsimile of the Conversion Notice;

(2) deliver the Conversion Notice, which is irrevocable, and the Security to the Conversion Agent;

(3) if required, furnish appropriate endorsements and transfer documents,

(4) if required, make any payment required under Section 4.02(f); and

(5) if required, pay all transfer or similar taxes as set forth in Section 4.02(g).

If, upon conversion of a Security, any shares of Common Stock are to be issued to a Person other than the Holder of such Security, the related Conversion Notice shall include such other Person’s name and address.

If a Security is subject to a Fundamental Change Purchase Notice, such Security may not be converted unless such Fundamental Change Purchase Notice is withdrawn in accordance with Section 3.04 hereof prior to the relevant Fundamental Change Expiration Time, except to the extent that a portion of such Holder’s Security is not subject to such Fundamental Change Purchase Notice.

For any Security, the first Business Day on which the Holder of such Security satisfies all of the applicable requirements set forth above with respect to such Security and on which conversion of such Security is not otherwise prohibited under this Indenture shall be the “Conversion Date” with respect to such Security.

Each conversion shall be deemed to have been effected as to any such Securities (or portion thereof) surrendered for conversion at the Close of Business on the applicable Conversion Date; provided, however, that the Person in whose name the certificate for any shares of Common Stock delivered upon conversion is registered shall be treated as a stockholder of record as of the Close of Business on (i) such Conversion Date (in the case of Physical Settlement) or (ii) the last Trading Day of the applicable Observation Period (in the case of Combination Settlement) except to the extent required by Section 4.04 hereof. At the Close of Business on the Conversion Date for a Security, the converting Holder shall no longer be the Holder of such Security.

(c) Endorsement. Any Securities surrendered for conversion shall, unless shares of Common Stock issuable on conversion are to be issued in the same name as the registration of such Securities, be duly endorsed by, or be accompanied by instruments of transfer in form satisfactory to the Company duly executed by, the Holder or its duly authorized attorney.

(d) Physical Securities. If any Securities in a denomination greater than $1,000 shall be surrendered for partial conversion, the Company shall execute and the Trustee shall authenticate and deliver to the Holder of the Securities so surrendered, without charge, new Securities in authorized denominations in an aggregate principal amount equal to the unconverted portion of the surrendered Securities.

17

(e) Global Securities. Upon the conversion of a beneficial interest in Global Securities, the Conversion Agent shall make a notation in its records as to the reduction in the principal amount represented thereby. The Company shall notify the Trustee in writing of any conversions of Securities effected through any Conversion Agent other than the Trustee.

(f) Interest Due Upon Conversion. If a Holder converts a Security after the Close of Business on a Regular Record Date but prior to the Open of Business on the Interest Payment Date corresponding to such Regular Record Date, such Holder must accompany such Security with an amount of cash equal to the amount of interest payable on such Security on the corresponding Interest Payment Date (regardless of whether the converting Holder was the Holder of record on the corresponding Regular Record Date); provided, however, that a Holder need not make such payment (1) if the Conversion Date follows the Regular Record Date immediately preceding the Maturity Date; (2) if the Company has specified a Fundamental Change Purchase Date that is after a Regular Record Date and on or prior to the corresponding Interest Payment Date; or (3) to the extent of any overdue interest, if any overdue interest exists at the time of conversion with respect to such Security.

(g) Taxes Due upon Conversion. If a Holder converts a Security, the Company will pay any documentary, stamp or similar issue or transfer tax due on the issue of any shares of the Common Stock upon the conversion, unless the tax is due because the Holder requests that any shares be issued in a name other than the Holder’s name, in which case the Holder will pay that tax.

Section 4.03 Settlement Upon Conversion.

(a) Settlement Amount. Subject to this Section 4.03 and Section 4.06(b), if a Holder converts a Security, the Company shall pay or deliver to such Holder, as the case may be, in respect of each $1,000 principal amount of Securities being converted, solely cash, solely shares of Common Stock (together with cash in lieu of fractional shares as provided herein) or a combination of cash and Common Stock (the “Settlement Amount”), at the Company’s election, as set forth in this Section 4.03.

(1) The Company shall pay or deliver, as the case may be, the Settlement Amount on the third Trading Day immediately following the last VWAP Trading Day of the Observation Period; provided, that;

(A) if the Company elects to fulfill its conversion obligation solely in shares of Common Stock (together with cash in lieu of fractional shares as provided herein), the Company shall deliver such Common Stock on the third Trading Day immediately following the relevant Conversion Date; and

(B) if prior to the relevant Conversion Date, the Common Stock has been replaced by Reference Property consisting solely of cash, pursuant to Section 4.07, the Company shall pay the cash due upon conversion as set forth in Section 4.07 on the third Trading Day immediately following the relevant Conversion Date.

(2) All conversions during the Final Conversion Period will be settled in the same relative proportions of cash and/or shares of Common Stock (the “Settlement Method”).

(3) Prior to the first day of the Final Conversion Period, the Company will elect (or be deemed to have elected) the same Settlement Method for all conversions occurring on any given Conversion Day. Except for any conversions that occur during the Final Conversion Period, the Company need not elect the same Settlement Method with respect to conversions that occur on different Conversion Dates.

(4) With respect to each Conversion Date occurring prior to the Final Conversion Period, the Company shall deliver a notice (each, a “Settlement Notice”) of the relevant Settlement Method not later than the Close of Business on the second Trading Day following the related Conversion Date. With respect to each Conversion Date occurring during the Final Conversion Period, the Company shall, prior to the Final Conversion Period, deliver a single Settlement Notice that shall apply to all conversions occurring during the Final Conversion Period. Each such Settlement Notice shall specify whether the Company shall satisfy its conversion obligation by (i) delivering solely shares of Common Stock (together with cash in lieu of fractional shares as provided herein) (“Physical Settlement”), (ii) paying solely cash (“Cash Settlement”) or (iii) paying and delivering, as the case may be, a combination of cash and shares of Common Stock (“Combination Settlement”). In the case of an election that provides for Combination Settlement, the relevant Settlement Notice shall indicate the Specified Dollar Amount. If the Company does not deliver a Settlement Notice within the time periods specified above, or if the Company provides a Settlement Notice within the time periods specified above and elects Combination Settlement but the Settlement Notice does not specify a Specified Dollar Amount, the Company will be deemed to have elected Combination Settlement with a Specified Dollar Amount of $1,000.

18

(5) The Settlement Amount in respect of any conversion shall be computed as follows:

(A) if the Company elects to satisfy its conversion obligation in respect of such conversion through Physical Settlement, the Company will deliver to the converting Holder a number of shares of Common Stock equal to (1) (i) the aggregate principal amount of Securities to be converted, divided by (ii) $1,000, multiplied by (2) the then-applicable Conversion Rate on the date the converting Holder becomes a record owner of Common Stock pursuant to the last paragraph of Section 4.02(b) (plus cash in lieu of any fractional shares);

(B) if the Company elects to satisfy its conversion obligation in respect of such conversion through Cash Settlement, the Company shall pay to the converting Holder cash in an amount per $1,000 principal amount of Securities being converted equal to the sum of the Daily Conversion Values for each of the 25 consecutive VWAP Trading Days during the related Observation Period; and

(C) if the Company elects to satisfy its conversion obligation in respect of such conversion through Combination Settlement, the Company shall pay and deliver to the converting Holder, as the case may be, in respect of each $1,000 principal amount of Securities being converted, a Settlement Amount equal to the sum of the Daily Settlement Amounts for each of the 25 consecutive VWAP Trading Days during the related Observation Period (plus cash in lieu of any fractional shares).

(6) The “Daily Settlement Amount” for each of the 25 consecutive VWAP Trading Days of the applicable Observation Period, will consist of:

(A) cash equal to the lesser of (i) a dollar amount per Security to be received upon conversion as specified by the Company in the Settlement Notice (the “Specified Dollar Amount”), if any, divided by 25 (such quotient being referred to as the “Daily Measurement Value”) and (ii) the Daily Conversion Value; and

(B) to the extent the Daily Conversion Value for such Trading Day exceeds the Daily Measurement Value for such Trading Day, a number of shares of Common Stock equal to (i) the difference between the Daily Conversion Value and the Daily Measurement Value, divided by (ii) the Daily VWAP of the Common Stock for such VWAP Trading Day.

(7) In the case of Cash Settlement or Combination Settlement, the Settlement Amount or Daily Conversion Values shall be determined by the Company promptly following the last day of the Observation Period. Promptly after such determination, the Company shall notify the Trustee and the Conversion Agent of the Daily Settlement Amounts or the Daily Conversion Values, as the case may be, and the amount of cash deliverable in lieu of fractional shares of Common Stock. The Trustee and the Conversion Agent shall be entitled to rely exclusively on the notice given by the Company and shall have no responsibility for any such determination.

(b) Fractional Shares. Notwithstanding the foregoing, the Company will not issue fractional shares of Common Stock with respect to any converted Security in respect of which shares of Common Stock are deliverable. Instead, if any such shares of Common Stock includes a fraction of a share of Common Stock, the Company will, in lieu of delivering such fraction of a share of Common Stock, pay an amount of cash equal to the product of (i) such fraction of a share and (ii) the Daily VWAP of the Common Stock on the relevant Conversion Date (in the case of Physical Settlement) or on the last Trading Day of the applicable Observation Period (in the case of Combination Settlement), subject in each case to the following paragraph.

If a Holder surrenders more than one Security for conversion on a single Conversion Date, the Company will calculate the amount of cash and the number of shares of Common Stock due with respect to such Securities as if such Holder had surrendered for conversion one Security having an aggregate principal amount equal to the sum of the principal amounts of each of the Securities surrendered for conversion by such Holder on such Conversion Date.

(c) Settlement of Accrued Interest and Deemed Payment of Principal. Subject to Section 4.02(f), if a Holder converts a Security, the Company will not adjust the Conversion Rate to account for any accrued and unpaid interest on such Security and the

19

Company’s delivery of the amount of cash and the number of shares of Common Stock, if any, into which a Security is convertible will be deemed to satisfy and discharge in full the Company’s obligation to pay the principal of, and accrued and unpaid interest, if any, on, such Security to, but excluding, the Conversion Date; provided, however, that if a Holder converts a Security after the Close of Business on a Regular Record Date and prior to the Open of Business on the corresponding Interest Payment Date, the Company will still be obligated to pay the interest due on such Interest Payment Date to the Holder of such Security on such Regular Record Date. As a result of the foregoing, and Section 4.02(f), the Company will pay accrued and unpaid interest on the Maturity Date on all Securities converted after the Regular Record Date immediately preceding the Maturity Date to the holders of record of such Securities on such Regular Record Date, and converting Holders will not be required to pay the Company equivalent amounts.

As a result, except as otherwise provided in the proviso to the first sentence of the immediately preceding paragraph, any accrued and unpaid interest with respect to a converted Security will be deemed to be paid in full rather than cancelled, extinguished or forfeited. In addition, except as otherwise provided in the proviso to the first sentence of the immediately preceding paragraph, if the Settlement Amount for any Security includes both cash and shares of the Common Stock, accrued and unpaid interest will be deemed to be paid first out of the amount of cash delivered upon such conversion. Except as otherwise provided herein, in no event will a Holder be entitled to receive any dividend or other distribution with respect to any Common Stock issued on conversion of such Holder’s Securities if the applicable Conversion Date is after the Regular Record Date for such dividend or distribution. Prior to any conversion in accordance with this Section 4.03, a Holder shall not be the owner of any Common Stock issuable upon conversion of such Holder’s Securities.

(d) Notices. Whenever a Conversion Date occurs with respect to a Security, the Conversion Agent will, as promptly as possible, and in no event later than the Business Day immediately following such Conversion Date, deliver to the Company and the Trustee, if it is not then the Conversion Agent, notice that a Conversion Date has occurred, which notice will state such Conversion Date, the principal amount of Securities converted on such Conversion Date and the names of the Holders that converted Securities on such Conversion Date.

Section 4.04 Adjustment of Conversion Rate. The Conversion Rate will be adjusted as described in this Section 4.04, except that the Company shall not make any adjustment to the Conversion Rate if Holders participate (other than in the case of a share split or share combination), at the same time and upon the same terms as holders of the Common Stock and as a result of holding the Securities, in any of the transactions described below without having to convert their Securities, as if they held a number of shares of Common Stock equal to the applicable Conversion Rate, multiplied by the principal amount (expressed in thousands) of Securities held by such Holder.

(a) If the Company exclusively issues shares of Common Stock as a dividend or distribution on all or substantially all shares of the Common Stock, or if the Company effects a share split or share combination, the Conversion Rate will be adjusted based on the following formula:

CR1                =        CR0 x	OS1
	OS0

where,

CR0	=	the Conversion Rate in effect immediately prior to the Open of Business on the Ex-Dividend Date of such dividend or distribution, or immediately prior to the Open of Business on the effective date of such share split or combination, as applicable;
CR1	=	the Conversion Rate in effect immediately after the Open of Business on such Ex-Dividend Date or such effective date;
OS0	=	the number of shares of Common Stock outstanding immediately prior to the Open of Business on such Ex-Dividend Date or such effective date, as applicable, before giving effect to such dividend, distribution, share split or share combination; and
OS1	=	the number of shares of Common Stock outstanding immediately after giving effect to such dividend, distribution, share split or share combination, as applicable.

20

Any adjustment made under this Section 4.04(a) shall become effective immediately after the Open of Business on the Ex-Dividend Date for such dividend or distribution, or immediately after the Open of Business on the effective date for such share split or share combination. If any dividend or distribution of the type described in this Section 4.04(a) is declared but not so paid or made, or any share split or share combination of the type described in this Section 4.04(a) is announced but the outstanding shares of the Common Stock are not split or combined, the Conversion Rate shall be immediately readjusted, effective as of the date the Board of Directors determines not to pay such dividend or distribution, or not to split or combine the outstanding shares of the Common Stock, to the Conversion Rate that would then be in effect if such dividend or distribution had not been declared or such share split or share combination had not been announced.

(b) If the Company issues to all or substantially all holders of the Common Stock any rights, options or warrants entitling them, for a period of not more than 45 calendar days after the date of such issuance, to subscribe for or purchase shares of the Common Stock, at a price per share less than the average of the Last Reported Sale Prices of the Common Stock for the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement of such issuance, the Conversion Rate will be increased based on the following formula:

CR1            =         CR0 x	OS0 + X
	OS0 + Y

where,

CR0	=	the Conversion Rate in effect immediately prior to the Open of Business on the Ex-Dividend Date for such issuance;
CR1	=	the Conversion Rate in effect immediately after the Open of Business on such Ex-Dividend Date;
OS0	=	the number of shares of Common Stock outstanding immediately prior to the Open of Business on such Ex-Dividend Date;
X	=	the total number of shares of Common Stock issuable pursuant to such rights, options or warrants; and
Y	=	the number of shares of Common Stock equal to the aggregate price payable to exercise such rights, options or warrants divided by the average of the Last Reported Sale Prices of the Common Stock over the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement of the issuance of such rights, options or warrants.

Any increase made under this Section 4.04(b) will be made successively whenever any such rights, options or warrants are issued and shall become effective immediately after the Open of Business on the Ex-Dividend Date for such issuance. To the extent that such rights, options or warrants are not exercised prior to their expiration or shares of Common Stock are not delivered upon the expiration of such rights, options or warrants, the Conversion Rate shall be readjusted to the Conversion Rate that would then be in effect had the increase with respect to the issuance of such rights, options or warrants been made on the basis of delivery of only the number of shares of Common Stock actually delivered. If such rights, options or warrants are not so issued, or if no such rights, options or warrants are exercised prior to their expiration, the Conversion Rate shall be decreased to be the Conversion Rate that would then be in effect if such Ex-Dividend Date for such issuance had not occurred.

For purposes of this Section 4.04(b) and Section 4.01(b)(3) hereof, in determining whether any rights, options or warrants entitle the holders of the Common Stock to subscribe for or purchase shares of the Common Stock at a price per share less than such average of the Last Reported Sale Prices of the Common Stock for the 10 consecutive Trading Day period ending on the Trading Day immediately preceding the date of announcement for such issuance, and in determining the aggregate offering price of such shares of the Common Stock, there shall be taken into account any consideration received by the Company for such rights, options or warrants and any amount payable on exercise or conversion thereof, the value of such consideration, if other than cash, to be determined by the Board of Directors.

21

(c) If the Company distributes shares of its Capital Stock, evidences of its indebtedness, other assets or property of the Company or rights, options or warrants to acquire its Capital Stock or other securities, to all or substantially all holders of the Common Stock, excluding:

(1) dividends, distributions, rights options or warrants as to which an adjustment was effected pursuant to Section 4.04(a) hereof or Section 4.04(b) hereof;

(2) dividends or distributions paid exclusively in cash; and

(3) Spin-Offs as to which the provisions set forth below in this Section 4.04(c) shall apply;

then the Conversion Rate shall be increased based on the following formula:

CR1                =        CR0 x	SP0
	SP0 - FMV

where,

CR0	=	the Conversion Rate in effect immediately prior to the Open of Business on the Ex-Dividend Date for such distribution;
CR1	=	the Conversion Rate in effect immediately after the Open of Business on such Ex-Dividend Date;
SP0	=	the average of the Last Reported Sale Prices of the Common Stock over the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the Ex-Dividend Date for such distribution; and
FMV	=	the fair market value (as determined by the Board of Directors) of the shares of the Company’s Capital Stock, evidences the Company’s indebtedness, other assets, or property of the Company or rights, options or warrants to acquire the Company’s Capital Stock or other securities distributed with respect to each outstanding share of the Common Stock on the Ex-Dividend Date for such distribution.

If “FMV” (as defined above) is equal to or greater than “SP₀” (as defined above) or if the difference between the “FMV” and “SP₀” is less than $1.00, in lieu of the foregoing increase, each Holder of Securities shall receive, in respect of each $1,000 principal amount of Securities it holds, at the same time and upon the same terms as holders of the Common Stock, the amount and kind of the Company’s Capital Stock, evidences of the Company’s indebtedness, other assets or property of the Company or rights, options or warrants to acquire the Company’s Capital Stock or other securities that such Holder would have received as if such Holder owned a number of shares of Common Stock equal to the Conversion Rate in effect on the Ex-Dividend Date for the distribution.

Any increase made under the portion of this Section 4.04(c) will become effective immediately after the Open of Business on the Ex-Dividend Date for such distribution. If such distribution is not so paid or made, the Conversion Rate shall be decreased to be the Conversion Rate that would then be in effect if such dividend or distribution had not been declared.

With respect to an adjustment pursuant to this Section 4.04(c) where there has been a payment of a dividend or other distribution on the Common Stock of shares of Capital Stock of any class or series, or similar equity interest, of or relating to a Subsidiary of the Company or other business unit of the Company, and such Capital Stock or similar equity interest is listed or quoted (or will be listed or quoted upon the consummation of the distribution) on a U.S. national securities exchange (a “Spin-Off”), the Conversion Rate will be increased based on the following formula:

CR1                =        CR0 x	FMV0 + MP0
	MP0

22

where,

CR0	=	the Conversion Rate in effect immediately prior to the Open of Business on the Ex-Dividend Date for such Spin-Off;
CR1	=	the Conversion Rate in effect immediately after the Open of Business on the Ex-Dividend Date for such Spin-Off;
FMV0	=	the average of the Last Reported Sale Prices of the Capital Stock or similar equity interest distributed to holders of Common Stock applicable to one share of Common Stock over the first 10 consecutive Trading Day period after, and including, the Ex-Dividend Date of the Spin-Off (the “Valuation Period”); and
MP0	=	the average of the Last Reported Sale Prices of Common Stock over the Valuation Period.

The adjustment to the applicable Conversion Rate under the preceding paragraph of this Section 4.04(c) will be made immediately after the Open of Business on the day after the last Trading Day of the Valuation Period, but will be given effect as of the Open of Business on the Ex-Dividend Date for the Spin-Off. If the Ex-Dividend Date for the Spin-Off is less than 10 Trading Days prior to, and including, the end of the Observation Period in respect of any conversion, references within this Section 4.04(c) to 10 Trading Days shall be deemed replaced, for purposes of calculating the affected Daily Conversion Values in respect of that conversion, with such lesser number of Trading Days as have elapsed from, and including, the Ex-Dividend Date for the Spin-Off to, and including, the last Trading Day of such Observation Period. For purposes of determining the applicable Conversion Rate, in respect of any conversion during the 10 Trading Days commencing on the Ex-Dividend Date for any Spin-Off, references within the portion of this Section 4.04(c) related to “Spin-Offs” to 10 Trading Days shall be deemed replaced with such lesser number of Trading Days as have elapsed from, and including, the Ex-Dividend Date for such Spin-Off to, and including, the relevant Conversion Date.

For purposes of the second adjustment set forth in this clause 4.04(c), (i) the Last Reported Sale Price of any Capital Stock or similar equity interest shall be calculated in a manner analogous to that used to calculate the Last Reported Sale Price of the Common Stock in the definition of “Last Reported Sale Price” set forth in Section 1.02 hereof, (ii) whether a day is a Trading Day (and whether a day is a Scheduled Trading Day and whether a Market Disruption Event has occurred) for such Capital Stock or similar equity interest shall be determined in a manner analogous to that used to determine whether a day is a Trading Day (or whether a day is a Scheduled Trading Day and whether a Market Disruption Event has occurred) for the Common Stock, and (iii) whether a day is a Trading Day to be included in a Valuation Period will be determined based on whether a day is a Trading Day for both the Common Stock and such Capital Stock or similar equity interest.

Subject to Section 4.04(g), for the purposes of this Section 4.04(c), rights, options or warrants distributed by the Company to all holders of the Common Stock entitling them to subscribe for or purchase shares of the Company’s Capital Stock (either initially or under certain circumstances), which rights, options or warrants, until the occurrence of a specified event or events (a “Trigger Event”): (1) are deemed to be transferred with such shares of Common Stock; (2) are not exercisable; and (3) are also issued in respect of future issuances of Common Stock, shall be deemed not to have been distributed for purposes of this Section 4.04(c), (and no adjustment to the Conversion Rate under this Section 4.04(c) will be required) until the occurrence of the earliest Trigger Event, whereupon such rights, options or warrants shall be deemed to have been distributed and an appropriate adjustment (if any is required) to the Conversion Rate shall be made under this Section 4.04(c). If any such right, option or warrant, distributed prior to the Issue Date are subject to events, upon the occurrence of which such rights, options or warrants become exercisable to purchase different securities, evidences of indebtedness or other assets, then the date of the occurrence of any and each such event shall be deemed to be the date of distribution and Ex-Dividend Date of such deemed distribution (in which case the original rights, options or warrants shall be deemed to terminate and expire on such date without exercise by any of the holders). In addition, in the event of any distribution or deemed distribution of rights, options or warrants, or any Trigger Event or other event (of the type described in the preceding sentence) with respect thereto that was counted for purposes of calculating a distribution amount for which an adjustment to the Conversion Rate under this Section 4.04(c) was made, (1) in the case of any such rights, options or warrants which shall all have been redeemed or purchased without exercise by any holders thereof, upon such final redemption or purchase (x) the Conversion Rate shall be readjusted as if such rights, options or warrants had not been issued and (y) the Conversion Rate shall then again be readjusted to give effect to such distribution, deemed distribution or Trigger Event, as the case may be, as though it were a cash distribution, equal to the per share redemption or purchase price received by holders of Common Stock with respect to such rights, options or warrants (assuming each such holder had retained such rights, options or warrants), made to all holders of Common Stock as of the date of such redemption or purchase, and (2) in the case of such rights, options or warrants which shall have expired or been terminated without exercise by any holders thereof, the Conversion Rate shall be readjusted as if such rights and warrants had not been issued.

23

For purposes of Section 4.04(a) hereof, Section 4.04(b) hereof and this Section 4.04(c), if any dividend or distribution to which this Section 4.04(c) applies includes one or both of:

(A) a dividend or distribution of shares of Common Stock to which Section 4.04(a) hereof also applies (the “Clause A Distribution”); or

(B) a dividend or distribution of rights, options or warrants to which Section 4.04(b) hereof also applies (the “Clause B Distribution”),

then (i) such dividend or distribution, other than the Clause A Distribution and the Clause B Distribution, shall be deemed to be a dividend or distribution to which this Section 4.04(c) applies (the “Clause C Distribution”) and any Conversion Rate adjustment required to be made under this Section 4.04(c) with respect to such Clause C Distribution shall be made, (ii) the Clause B Distribution, if any, shall be deemed to immediately follow the Clause C Distribution and any Conversion Rate adjustment required by Section 4.04(b) hereof with respect thereto shall then be made, except that, if determined by the Company, (A) the “Ex-Dividend Date” of the Clause B Distribution and the Clause A Distribution, if any, shall be deemed to be the Ex-Dividend Date of the Clause C Distribution and (B) any shares of Common Stock included in the Clause A Distribution or the Clause B Distribution shall not be deemed to be “outstanding immediately prior to the Open of Business on such Ex-Dividend Date” within the meaning of Section 4.04(b) hereof, and (iii) the Clause A Distribution, if any, shall be deemed to immediately follow the Clause C Distribution or the Clause B Distribution, as the case may be, except that, if determined by the Company, (A) the “Ex-Dividend Date” of the Clause A Distribution and the Clause B Distribution, if any, shall be deemed to be the Ex-Dividend Date of the Clause C Distribution, and (B) any shares of Common Stock included in the Clause A distribution shall not be deemed to be “outstanding immediately prior to the Open of Business on such Ex-Dividend Date or such effective date” within the meaning of Section 4.04(a) hereof.

(d) If any cash dividend or distribution is made to all or substantially all holders of the Common Stock to the extent that the aggregate of all such cash dividends or distributions paid in any quarter exceeds the dividend threshold amount (the “DTA”) for such quarter, the Conversion Rate shall be adjusted based on the following formula:

CR1                =        CR0 x	SP0
	SP0 – C

where,

CR0	=	the Conversion Rate in effect immediately prior to the Open of Business on the Ex-Dividend Date for such dividend or distribution;
CR1	=	the Conversion Rate in effect immediately after the Open of Business on the Ex-Dividend Date for such dividend or distribution;
SP0	=	the Last Reported Sale Price of the Common Stock on the Trading Day immediately preceding the Ex-Dividend Date for such dividend or distribution;
DTA	=	the dividend threshold amount, which shall initially be $0.62 per quarter; and
C	=	the amount in cash per share that the Company distributes to holders of the Common Stock in excess of the DTA

The DTA is subject to adjustment on an inversely proportional basis whenever the Conversion Rate is adjusted other than adjustments made pursuant to this Section 4.04(d). If an adjustment is required to be made as set forth in this Section 4.04(d) as a result of a distribution that is not a regular, periodic dividend, the DTA will be deemed to be zero with respect to that particular adjustment. Notwithstanding the foregoing, if at any time dividends are distributed other than on a quarterly basis, the DTA shall be appropriately adjusted and shall apply to such dividends.

24

If “C” (as defined above) is equal to or greater than “SP₀” (as defined above) or if the difference between “C” and “SP₀” is less than $1.00, in lieu of the foregoing increase, each Holder shall receive, for each $1,000 principal amount of Securities it holds, at the same time and upon the same terms as holders of shares of the Common Stock, the amount of cash that such Holder would have received if such Holder had owned a number of shares of Common Stock equal to the Conversion Rate on the Ex-Dividend Date for such cash dividend or distribution. Any increase made pursuant to this Section 4.04(d) shall become effective immediately after the Open of Business on the Ex-Dividend Date for such dividend or distribution. If such dividend or distribution is not so paid, the Conversion Rate shall be decreased to be the Conversion Rate that would then be in effect if such dividend or distribution had not been declared.

(e) If the Company or any of its Subsidiaries make a payment in respect of a tender offer or exchange offer for the Common Stock, to the extent that the cash and value of any other consideration included in the payment per share of the Common Stock exceeds the Last Reported Sale Price of the Common Stock on the Trading Day next succeeding the last date on which tenders or exchanges may be made pursuant to such tender or exchange offer (the “Offer Expiration Date”), the Conversion Rate shall be increased based on the following formula:

CR1                =        CR0 x	AC + (SP1 x OS1)
	OS0 x SP1

where,

CR0	=	the Conversion Rate in effect immediately prior to the Close of Business on the Offer Expiration Date;
CR1	=	the Conversion Rate in effect immediately after the Close of Business on the Offer Expiration Date;
AC	=	the aggregate value of all cash and any other consideration (as determined by the Board of Directors) paid or payable for shares of Common Stock purchased in such tender offer or exchange offer;
OS0	=	the number of shares of Common Stock outstanding immediately prior to the expiration time of the tender or exchange offer on the Offer Expiration Date (prior to giving effect to the purchase of all shares accepted for purchase or exchange in such tender offer or exchange offer);
OS1		the number of shares of Common Stock outstanding immediately after the expiration time of the tender or exchange offer on the Offer Expiration Date (after giving effect to the purchase of all shares accepted for purchase or exchange in such tender or exchange offer); and
SP1		the average of the Last Reported Sale Prices of the Common Stock over the 10 consecutive Trading Day period commencing on, and including, the Trading Day next succeeding the Offer Expiration Date.

The adjustment to the applicable Conversion Rate under the preceding paragraph of this Section 4.04(e) will be given effect at the Open of Business on the Trading Day next succeeding the Offer Expiration Date. If the Trading Day next succeeding the Offer Expiration Date is less than 10 Trading Days prior to, and including, the end of the Observation Period in respect of any conversion, references within this Section 4.04(e) to 10 Trading Days shall be deemed replaced, solely in respect of such conversion, for purposes of calculating the affected Daily Conversion Values in respect of that conversion, with such lesser number of Trading Days as have elapsed from, and including, the Trading Day next succeeding the Offer Expiration Date to, and including, the last Trading Day of such Observation Period. For purposes of determining the applicable Conversion Rate, in respect of any conversion during the 10 Trading Days commencing on the Trading Day next succeeding the Offer Expiration Date, references within this Section 4.04(e) to 10 Trading Days shall be deemed replaced, solely in respect of such conversion, with such lesser number of Trading Days as have elapsed from, and including, the Trading Day next succeeding the Offer Expiration Date to, and including, the relevant Conversion Date.

25

(f) Special Settlement Provisions. Notwithstanding anything to the contrary herein, with respect to any Securities as to which Physical Settlement is applicable, if a Conversion Rate adjustment becomes effective on any Ex-Dividend Date as described above, and a Holder that has converted its Securities on or prior to the related Regular Record Date would be treated as the record holder of shares of Common Stock in accordance with the provisions of the last paragraph of Section 4.02(b) as of a date on or after such Ex-Dividend Date, then, notwithstanding the foregoing Conversion Rate adjustment provisions, the Conversion Rate adjustment relating to such Ex-Dividend Date will not be made for such converting Holder. Instead, such Holder will be treated as if such Holder were the record owner of the shares of Common Stock on an unadjusted basis and participate in the related dividend, distribution or other event giving rise to such adjustment.

(g) Poison Pill. Whenever a Holder converts a Security, to the extent that the Company has a rights plan in effect, the Holder converting such Security will receive, in addition to any shares of Common Stock otherwise received in connection with such conversion, the rights under the rights plan unless the rights have separated from the Common Stock, in which case, and only in such case, the Conversion Rate will be adjusted at the time of separation as if the Company distributed to all holders of the Common Stock, shares of Capital Stock, evidences of indebtedness, assets, property, rights, options or warrants as described in Section 4.04(c) hereof, subject to readjustment in the event of the expiration, termination or redemption of such rights.

(h) Deferral of Adjustments. Notwithstanding anything to the contrary herein, except on and after the first VWAP Trading Day of any Observation Period with respect to a Security and on or prior to the last VWAP Trading Day of such Observation Period, the Company will not be required to adjust the Conversion Rate unless such adjustment would require an increase or decrease of at least one percent; provided, however, that any such minor adjustments that are not required to be made will be carried forward and taken into account in any subsequent adjustment, and provided, further, that any such adjustment of less than one percent that has not been made shall be made upon the occurrence of (i) the Effective Date for any Make-Whole Fundamental Change, (ii) the first VWAP Trading Day of any Observation Period and (iii) if the Company elects to satisfy its conversion obligation solely in shares of Common Stock, upon any conversion of Securities. In addition, the Company shall not account for such deferrals when determining whether any of the conditions to conversion have been satisfied or what number of shares of Common Stock a Holder would have held on a given day had it converted its Securities.

(i) Limitation on Adjustments. Except as stated in this Section 4.04, the Company will not adjust the Conversion Rate for the issuance of shares of Common Stock or any securities convertible into or exchangeable for shares of Common Stock or the right to purchase shares of the Common Stock or such convertible or exchangeable securities. If, however, the application of the formulas in Sections 4.04(a) through (e) hereof would result in a decrease in the Conversion Rate, then, except to the extent of any readjustment to the Conversion Rate, no adjustment to the Conversion Rate will be made (other than as a result of a reverse share split, share combination or readjustment).

In addition, notwithstanding anything to the contrary herein, the Conversion Rate will not be adjusted:

(1) on account of stock repurchases that are not tender offers referred to in Section 4.04(e) hereof, including structured or derivative transactions, or transactions pursuant to a stock repurchase program approved by the Board of Directors or otherwise;

(2) upon the issuance of any shares of Common Stock pursuant to any present or future plan providing for the reinvestment of dividends or interest payable on the Company’s securities and the investment of additional optional amounts in shares of Common Stock under any plan;

(3) upon the issuance of any shares of Common Stock or options or rights to purchase those shares pursuant to any present or future employee, director or consultant benefit plan, program or agreement of or assumed by the Company or any of its Subsidiaries;

(4) upon the issuance of any shares of Common Stock pursuant to any option, warrant, right or exercisable, exchangeable or convertible security not described in the preceding clause (3) and outstanding as of the date the Securities were first issued;

(5) for a change in the par value of the Common Stock;

26

(6) for accrued and unpaid interest on the Securities, if any; or

(7) for an event otherwise requiring an adjustment under this Indenture if such event is not consummated.

(j) For purposes of this Section 4.04, the number of shares of Common Stock at any time outstanding shall not include shares held in the treasury of the Company so long as the Company does not pay any dividend or make any distribution on shares of Common Stock held in the treasury of the Company, but shall include shares issuable in respect of scrip certificates issued in lieu of fractions of shares of Common Stock.

(k) Withholding on Adjustments. If, in connection with any adjustment to the Conversion Rate as set forth in this Section 4.04, a Holder shall be deemed for U.S. federal tax purposes to have received a distribution and the Company reasonably believes it is required to collect withholding tax with respect to any such deemed distribution, the Company may withhold from cash payments of interest in accordance with the provisions of Section 2.04 hereof or from cash and Common Stock, if any, otherwise deliverable to a Holder upon a conversion of Securities in accordance with the provisions of Section 4.03 hereof or repurchase of a Security in accordance with the provisions of Article 3 hereof.

Section 4.05 Other Adjustments.

(a) Adjustments of Prices. Whenever any provision of this Indenture requires the Company to calculate the Last Reported Sale Prices, the Daily VWAPs or any function thereof over a span of multiple days (including during an Observation Period), the Company will make appropriate adjustments to each to account for any adjustment to the Conversion Rate that becomes effective, or any event requiring an adjustment to the Conversion Rate where the Effective Date, Ex-Dividend Date or Offer Expiration Date of the event occurs, at any time during the period when such Last Reported Sale Prices, the Daily VWAPs or function thereof is to be calculated.

(b) Voluntary Adjustments. To the extent permitted by applicable law, the Company is permitted to increase the Conversion Rate of the Securities by any amount for a period of at least 20 Business Days if the Board of Directors determines that such increase would be in the Company’s best interest. The Company may also (but is not required to) increase the Conversion Rate to avoid or diminish income tax to holders of Common Stock or rights to purchase shares of Common Stock in connection with a dividend or distribution of shares (or rights to acquire shares) or similar event.

Section 4.06 Adjustment to Conversion Rate Upon Conversion in Connection with a Make-Whole Fundamental Change.

(a) Increase in the Conversion Rate. If a Make-Whole Fundamental Change occurs and a Holder elects to convert its Securities in connection with such Make-Whole Fundamental Change, the Company shall, under certain circumstances, increase the Conversion Rate for the Securities so surrendered for conversion by a number of additional shares of Common Stock (the “Additional Shares”), as described in this Section 4.06. A conversion of Securities shall be deemed for these purposes to be “in connection with” a Make-Whole Fundamental Change if the relevant Conversion Notice is received by the Conversion Agent during the period from, and including, the Effective Date of the Make-Whole Fundamental Change up to, and including, the Close of Business on the Business Day immediately prior to the related Fundamental Change Purchase Date or, if such Make-Whole Fundamental Change is not a Fundamental Change, the 35th Business Day immediately following the Effective Date for such Make-Whole Fundamental Change.

(b) Cash Mergers. Notwithstanding anything to the contrary herein, if the consideration paid for the Common Stock in any Make-Whole Fundamental Change described in clause (2) of the definition of Fundamental Change is comprised entirely of cash, then, for any conversion of Securities following the Effective Date of such Make-Whole Fundamental Change, the payment and delivery obligations upon the conversion of a Security shall be calculated based solely on the Stock Price for such Make-Whole Fundamental Change and shall, for each $1,000 principal amount of Securities converted, be deemed to be an amount of cash equal to the product of (i) the Conversion Rate in effect on the applicable Conversion Date (as increased by any number of Additional Shares required by this Section 4.06) multiplied by (ii) such Stock Price. In such event, the Company will determine the settlement amount and pay such amount of cash to a converting Holder on the third Business Day following the applicable Conversion Date. Otherwise, the Company will settle any conversion of the Securities following the Effective Date for a Make-Whole Fundamental Change in accordance with Section 4.02 hereof (but subject to Section 4.07 hereof).

27

(c) Determining the Number of Additional Shares. The number of Additional Shares, if any, by which the Conversion Rate will be increased for a Holder that converts its Securities in connection with a Make-Whole Fundamental Change shall be determined by reference to the table attached as Schedule A hereto, based on the date on which the Make-Whole Fundamental Change occurs or becomes effective (the “Effective Date”) and the price (the “Stock Price”) paid (or deemed paid) per share of the Common Stock in the Make-Whole Fundamental Change. If the holders of the Common Stock receive only cash in a Make-Whole Fundamental Change described in clause (2) of the definition of Fundamental Change, the Stock Price shall be the cash amount paid per share. Otherwise, the Stock Price shall be the average of the Last Reported Sale Prices of the Common Stock over the ten consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the Effective Date of the Make-Whole Fundamental Change.

(d) Interpolation and Limits. The exact Stock Prices and Effective Dates may not be set forth in the table in Schedule A, in which case:

(1) If the Stock Price is between two Stock Prices in the table or the Effective Date is between two Effective Dates in the table, the number of Additional Shares by which the Conversion Rate will be increased shall be determined by a straight-line interpolation between the number of Additional Shares set forth for the higher and lower Stock Prices and the earlier and later Effective Dates, as applicable, based on a 365-day year.

(2) If the Stock Price is greater than $42.50 per share (subject to adjustment in the same manner as the Stock Prices set forth in the column headings of the table in Schedule A pursuant to Section 4.06(d)(4) hereof), the Conversion Rate shall not be increased.

(3) If the Stock Price is less than $31.02 per share (subject to adjustment in the same manner as the Stock Prices set forth in the column headings of the table in Schedule A pursuant to Section 4.06(d)(4) hereof), the Conversion Rate shall not be increased.

Notwithstanding the foregoing, in no event will the Conversion Rate be increased on account of a Make-Whole Fundamental Change to exceed 32.2373 shares of Common Stock per $1,000 principal amount of Securities, subject to adjustment in the same manner as the Conversion Rate is required to be adjusted as set forth in Section 4.04 hereof.

(4) The Stock Prices set forth in the column headings of the table in Schedule A hereto shall be adjusted as of any date on which the Conversion Rate of the Securities is otherwise required to be adjusted. The adjusted Stock Prices shall equal the Stock Prices applicable immediately prior to such adjustment, multiplied by a fraction, the numerator of which is the Conversion Rate immediately prior to such adjustment giving rise to the Stock Price adjustment and the denominator of which is the Conversion Rate as so adjusted. The number of Additional Shares set forth in such table shall be adjusted in the same manner and at the same time as the Conversion Rate is required to be adjusted as set forth in Section 4.04.

(e) Notices. The Company shall notify the Holders of the Effective Date of any Make-Whole Fundamental Change and issue a press release announcing such Effective Date no later than five Business Days after such Effective Date.

Section 4.07 Effect of Recapitalization, Reclassification, Consolidation, Merger or Sale.

(a) Merger Events. In the case of:

(1) any recapitalization, reclassification or change of the Common Stock (other than a change in par value, or from par value to no par value, or from no par value to par value, or as a result of a split, subdivision or combination for which an adjustment is made pursuant to Section 4.04(a) hereof);

(2) any consolidation, merger or combination involving the Company;

28

(3) any sale, lease or other transfer to a third party of the consolidated assets of the Company and its Subsidiaries substantially as an entirety; or

(4) any statutory share exchange;

and, in each case, as a result of which the Common Stock would be converted into, or exchanged for, stock, other securities, other property or assets (including cash or any combination thereof) (any such event, a “Merger Event,” any such stock, other securities, other property or assets, “Reference Property,” and the amount of kind of Reference Property that a holder of one share of Common Stock (i) is entitled to receive in the applicable Merger Event or (ii) if, as a result of the applicable Merger Event, each share of Common Stock is converted into the right to receive more than a single type of consideration (determined based in part upon any form of stockholder election), the per-share of Common Stock weighted average of the types and amounts of Reference Property received by the holders of Common Stock that affirmatively make such an election, a “Unit of Reference Property”) then, at the effective time of such Merger Event, the right to convert each $1,000 principal amount of Securities based on a number of shares of the Common Stock equal to the applicable Conversion Rate will, without the consent of the Holders, be changed into a right to convert each $1,000 principal amount of Securities based on a number of Units of Reference Property equal to the applicable Conversion Rate and, prior to or at the effective time of such Merger Event, the Company or the successor or purchasing Person, as the case may be, shall execute with the Trustee a supplemental indenture (which shall comply with the Trust Indenture Act as in force at the date of execution of such supplemental indenture) providing for such change in the right to convert each $1,000 principal amount of Securities; provided, however, that (i) any amount payable in cash upon conversion of the Securities in accordance with Sections 4.03 and 4.06 hereof shall continue to be payable in cash, (ii) the number of shares of Common Stock that the Company would have been required to deliver upon conversion of the Securities in accordance with Sections 4.03 and 4.06 hereof shall instead be deliverable in Units of Reference Property and (iii) the Daily VWAP and the Last Reported Sale Price will, to the extent reasonably possible, be calculated based on the value of a Unit of Reference Property and the definitions of Trading Day and Market Disruption Event shall be determined by reference to the components of a Unit of Reference Property; provided, further, that if the holders receive only cash in such Merger Event, (i) the consideration due shall be solely in cash in an amount equal to the Conversion Rate in effect on the Conversion Date (as may be increased by any Additional Shares pursuant to Section 4.06), multiplied by the price paid per share of Common Stock in such Merger Event and (ii) settlement will occur on the third Business Day immediately following the Conversion Date.

If the Merger Event causes the Common Stock to be converted into, or exchanged for, the right to receive more than a single type of consideration (determined based in part upon any form of stockholder election) as contemplated by the preceding paragraph such that a Unit of Reference Property is comprised of the per-share of Common Stock weighted average of the types and amounts of consideration received by the holders of the Common Stock in the Merger Event that affirmatively make such an election, the Company shall notify Holders of the weighted average as soon as practicable after such determination is made.

The Company shall not become a party to any Merger Event unless its terms are consistent with this Section 4.07. Such supplemental indenture described in the second immediately preceding paragraph shall provide for adjustments which shall be as nearly equivalent to the adjustments provided for in this Article 4 in the judgment of the Board of Directors or the board of directors of the successor Person. If, in the case of any such Merger Event, the Reference Property receivable thereupon by a holder of Common Stock includes shares of stock, securities or other property or assets (including cash or any combination thereof) of a Person other than the successor or purchasing Person, as the case may be, in such Merger Event, then such supplemental indenture shall also be executed by such other Person.

(b) Notice of Supplemental Indentures. The Company shall cause notice of the execution of any supplemental indenture entered into pursuant to Section 4.07(a) above to be either mailed to each Holder at the address of such Holder as it appears on the register of the Securities maintained by the Security Registrar or sent electronically to each Holder in accordance with Applicable Procedures, within 20 days after execution thereof. Failure to deliver such notice shall not affect the legality or validity of such supplemental indenture. The above provisions of this Section 4.07 shall similarly apply to successive Merger Events.

(a) Reservation of Shares. To the extent necessary to satisfy its obligations under this Indenture, prior to issuing any shares of Common Stock, the Company will reserve out of its authorized but unissued shares of Common Stock a sufficient number of shares of Common Stock to permit the conversion of the Securities.

(b) Certain other Covenants. The Company covenants that all shares of Common Stock that may be issued upon conversion of Securities shall be newly issued shares or treasury shares, shall be duly authorized, validly issued, fully paid and non-assessable and shall be free from preemptive rights and free from any tax, lien or charge (other than those created by the Holder or due to a change in registered owner).

(3) Dissolutions, Liquidations and Winding-Ups. If there is a voluntary or involuntary dissolution, liquidation or winding-up of the Company, the Company shall deliver notice to the Holders at promptly as possible, but in any event at least 15 calendar days prior to the earlier of (i) the date on which such dissolution, liquidation or winding-up, as the case may be, is expected to become effective or occur, and (ii) the date as of which it is expected that holders of Common Stock of record shall be entitled to exchange their Common Stock for securities or other property deliverable upon such dissolution, liquidation or winding-up, as the case may be, which notice shall state the expected effective date and record date for such event, as applicable, and the amount and kind of property that a holder of one share of the Common Stock is expected to be entitled, or may elect, to receive in such event. The Company shall deliver an additional notice to holders, as promptly as practicable, whenever the expected effective date or record date, as applicable, or the amount and kind of property that a holder of one share of the Common Stock is expect to be entitled to receive in such event, changes.

(b) Notices After Certain Actions and Events. Whenever an adjustment to the Conversion Rate becomes effective pursuant to Sections 4.04, 4.05 or 4.06 hereof, the Company will (i) file with the Trustee an Officers’ Certificate stating that such adjustment has become effective, the Conversion Rate, and the manner in which the adjustment was computed and (ii) deliver notice to the Holder’s stating that such adjustment has become effective and the Conversion Rate or conversion privilege as adjusted. Failure to give any such notice, or any defect therein, shall not affect the validity of any such adjustment.

Section 4.11 Limit on Issuance of Shares of Common Stock Upon Conversion. Notwithstanding anything to the contrary in this Supplemental Indenture, if an event occurs that would result in an increase in the Conversion Rate by an amount in excess of limitations imposed by The New York Stock Exchange, the Company shall, at its option, either obtain stockholder approval of any issuance of Common Stock upon conversion of the Notes in excess of such limitations or pay cash in lieu of delivering any shares of Common Stock otherwise deliverable upon conversions in excess of such limitations based on the Daily VWAP for each Trading Day of the relevant Observation Period in respect of which, in lieu of delivering shares of Common Stock, the Company pays cash pursuant to this Section 4.11.

The Company may also from time to time designate coregistrars one or more other offices or agencies where the Securities may be presented or surrendered for any or all such purposes and may from time to time rescind such designations; provided that no such designation or rescission shall in any manner relieve the Company of its obligation to maintain an office or agency in the Borough of Manhattan, The City of New York, for such purposes. The Company will give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other office or agency. The terms “Paying Agent” and “Conversion Agent” include any such additional or other offices or agencies, as applicable.

The Company hereby initially designates the Trustee as the Paying Agent, Security Registrar, Custodian, Conversion Agent and the Corporate Trust Office, which shall be in the continental United States, shall be considered as one such office or agency of the Company for each of the aforesaid purposes.

With respect to any Global Security, the Corporate Trust Office of the Trustee or any Paying Agent shall be the Place of Payment where such Global Security may be presented or surrendered for payment or conversion or for registration of transfer or exchange, or where successor Securities may be delivered in exchange therefor; provided, however, that any such payment, conversion, presentation, surrender or delivery effected pursuant to the Applicable Procedures of the Depositary for such Global Security shall be deemed to have been effected at the Place of Payment for such Global Security in accordance with the provisions of this Indenture.

Section 5.03 Appointments to Fill Vacancies in Trustee’s Office. The Company, whenever necessary to avoid or fill a vacancy in the office of Trustee, will appoint, in the manner provided in Section 7.09 of the Base Indenture, a Trustee, so that there shall at all times be a Trustee hereunder.

Section 5.04 Provisions as to Paying Agent. This Section 5.04 shall replace Section 4.03 of the Base Indenture in its entirety and references in the Base Indenture to Section 4.03 of the Base Indenture shall be deemed replace with references to this Section 5.04.

(a) If the Company shall appoint a Paying Agent other than the Trustee, the Company will cause such Paying Agent to execute and deliver to the Trustee an instrument in which such agent shall agree with the Trustee, subject to the provisions of this Section 5.04:

(1) that it will hold all sums held by it as such agent for the payment of the principal of, accrued and unpaid interest, if any, on, and the Fundamental Change Purchase Price for, the Securities in trust for the benefit of the holders of the Securities;

(3) that at any time during the continuance of an Event of Default, upon request of the Trustee, it will forthwith pay to the Trustee all sums so held in trust.

The Company shall, on or before each due date of the principal of, accrued and unpaid interest, if any, on, and Fundamental Change Purchase Price for, the Securities, deposit with the Paying Agent a sum sufficient to pay such principal, accrued and unpaid interest, or Fundamental Change Purchase Price, as the case may be, and (unless such Paying Agent is the Trustee) the Company will promptly notify the Trustee of any failure to take such action, provided that, if such deposit is made on the due date, such deposit must be received by the Paying Agent by 10:00 a.m., New York City time, on such date.

(b) If the Company shall act as its own Paying Agent, it will, on or before each due date of the principal of, accrued and unpaid interest, if any, on, or Fundamental Change Purchase Price for, the Securities, set aside, segregate and hold in trust for the benefit of the holders of the Securities a sum sufficient to pay such principal, accrued and unpaid interest, if any, on or Fundamental

(c) Anything in this Section 5.04 to the contrary notwithstanding, the Company may, at any time, for the purpose of obtaining a satisfaction and discharge of this Indenture, or for any other reason, pay or cause to be paid to the Trustee all sums held in trust by the Company or any Paying Agent hereunder as required by this Section 5.04, such sums to be held by the Trustee upon the trusts herein contained and upon such payment by the Company or any Paying Agent to the Trustee, the Company or such Paying Agent shall be released from all further liability with respect to such sums.

Section 5.05 Reports. This Section 5.05 will replace Section 5.03 of the Base Indenture in its entirety.

The Company will file with the Trustee, within 15 days after it is required to file the same with the SEC, copies of the quarterly and annual reports and of the information, documents and other reports, if any, that it is required to file with the SEC pursuant to Section 13 or 15(d) of the Exchange Act, and to otherwise comply with Section 314(a) of the Trust Indenture Act. Any such report, information or document that the Company files with the SEC through the EDGAR system (or any successor thereto) will be deemed to be delivered to the Trustee for the purposes of this Section 5.05 at the time of such filing through the EDGAR system (or such successor thereto).

Delivery of any such reports, information and documents to the Trustee shall be for informational purposes only, and the Trustee’s receipt of such reports, information and documents shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Company’s compliance with any of its covenants hereunder (as to which the Trustee is entitled to rely exclusively on Officers’ Certificates).

Section 5.06 Statements as to Defaults. The Company shall deliver to the Trustee, as soon as possible, and in any event within thirty days after the Company becomes aware of the occurrence of any Default or Event of Default, an Officers’ Certificate setting forth the details of such Default or Event of Default, its status and the action that the Company proposes to take with respect thereto. Such Officers’ Certificate shall also comply with any additional requirements set forth in Section 13.06 of the Base Indenture.

Section 5.08 Covenant to Take Certain Actions. Before taking any action which would cause an adjustment to the Conversion Rate such that the Conversion Price per share of Common Stock issuable upon conversion of the Securities would be less than the par value of the Common Stock, the Company shall take all corporate actions that may, in the opinion of its counsel, be necessary so it may validly and legally issue shares of Common Stock at such adjusted Conversion Rate.

34

Section 6.04 Supplementary Interest.

(a) Notwithstanding any provisions of the Indenture to the contrary, if the Company so elects, the sole remedy for an Event of Default relating to (i) the Company’s failure to file with the Trustee pursuant to Section 314(a)(1) of the Trust Indenture Act any documents or reports that it is required to file with the Commission pursuant to Section 13 or 15(d) of the Exchange Act, or (ii) the Company’s failure to comply with Section 5.05 hereof (a “Reporting Event of Default”), will, for the first 365 days after the occurrence of such an Event of Default, consist exclusively of the right to receive additional interest on the Securities (the “Supplementary Interest”) at a rate equal to (i) 0.25% per annum of the Outstanding principal amount of the Securities for each day during the 185-day period on which such Event of Default is continuing beginning on, and including, the date on which such an Event of Default first occurs and (ii) 0.50% per annum of the Outstanding principal amount of the Securities for each day during the 180-day period on which such Event of Default is continuing beginning on, and including the 186^th day on which such Event of Default is continuing. If the Company so elects, such Supplemental Interest will be payable in the same manner and on the same dates as the stated interest payable on the Securities. On the 366th day after such Event of Default (if the Reporting Event of Default is not cured or waived prior to such 366th day), the Securities will be subject to acceleration pursuant to Section 6.03. The provisions of this Section 6.04 will not affect the rights of Holders of Securities in the event of the occurrence of any Event of Default that is not a Reporting Event of Default. In the event the Company does not elect to pay the Supplemental Interest following an Event of Default in accordance with this Section 6.04 or the Company elected to make such payment but do not pay the Supplemental Interest when due, the Securities will be immediately subject to acceleration as provided in Section 6.03.

(b) In order to elect to pay the Supplemental Interest as the sole remedy during the first 365 days after the occurrence of an Reporting Event of Default, the Company must notify all Holders of Securities, the Trustee and the Paying Agent of such election prior to the beginning of such 365-day period. Upon the Company’s failure to timely give such notice, the Securities will be immediately subject to acceleration as provided in Section 6.03.

Section 6.05 Waiver of Past Defaults. The Trustee may withhold notice to the Holders of Securities of any Default or Event of Default, except a Default or Event of Default relating to the payment of principal or interest or the failure to deliver the consideration due upon conversion, if it determines that withholding such notice is in the Holders’ interest. The Holders of a majority in principal amount of the Securities may waive any Default or Event of Default with respect to the Securities and its consequences, except a continuing Default or Event of Default in the payment of principal or interest on the Securities or the failure to deliver the consideration due upon conversion. Any such waiver shall cure such Default or Event of Default.

Section 6.06 Control by Majority. At any time, the Holders of a majority of the aggregate principal amount of the then Outstanding Securities may direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or for exercising any trust or power conferred on the Trustee, with respect to the Securities, provided that:

(a) the Trustee may refuse to follow any direction that conflicts with law or this Indenture;

(b) the Trustee may take any other action deemed proper by it which is not inconsistent with such direction; and

(c) subject to the Trustee’s duties under the Trust Indenture Act, the Trustee need not take any action that might involve it in personal liability or might be unduly prejudicial to the Holders not involved in the proceeding.

Prior to taking any action hereunder, the Trustee will be entitled to indemnification reasonably satisfactory to it against all losses and expenses caused by taking or not taking such action.

Section 6.07 Limitation on Suits. A Holder of the Securities will only have the right to institute a proceeding under the Indenture or to appoint a receiver or trustee, or to seek other remedies if:

(a) the Holder has delivered to the Trustee written notice that an Event of Default has occurred and is continuing with respect to the Securities;

(b) the Holders of at least 25% of the aggregate principal amount of the Securities have made written request, and such Holders have offered indemnity to the Trustee satisfactory to the Trustee to institute such proceedings as Trustee; and

(c) the Trustee does not institute such proceeding, and does not receive from the Holders of a majority in the aggregate principal amount of the Outstanding Securities other conflicting directions within 60 days after such notice, request and offer.

35

A Holder may not use this Indenture to prejudice the rights of any other Holder or to obtain a preference or priority over any other Holder, it being understood that the Trustee does not have any affirmative duty to ascertain whether any usage of this Indenture by a Holder is unduly prejudicial to such other Holders.

Section 6.08 Rights of Holders to Receive Payment and to Convert. Notwithstanding anything to the contrary elsewhere in this Indenture, the right of any Holder to receive payment of the principal of, interest on, Fundamental Change Purchase Price for, its Securities, on or after the respective due date, and to convert its Securities and receive payment or delivery of the consideration due with respect to such Securities in accordance with Article 4 hereof, or to bring suit for the enforcement of any such payment or conversion rights, will not be impaired or affected without the consent of such Holder and will not be subject to the requirements of Section 6.07 hereof.

Section 6.09 Collection of Indebtedness; Suit for Enforcement by Trustee. If an Event of Default specified in Section 6.02(a), 6.02(b) or 6.02(c) hereof occurs and is continuing, the Trustee is authorized to recover judgment in its own name and as trustee of an express trust against the Company for the whole amount of principal of, interest on, Fundamental Change Purchase Price for, and the amount of cash or the combination of cash and shares of Common Stock, if any, as the case may be, due upon the conversion of, the Securities, as the case may be, and such further amount as is sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, as well as any other amounts that may be due under Section 7.06 of the Base Indenture.

Section 6.10 Trustee May Enforce Claims Without Possession of Securities. All rights of action and claims under this Indenture or the Securities may be prosecuted and enforced by the Trustee without the possession of any of the Securities or the production thereof in any proceeding relating thereto, and any such proceeding instituted by the Trustee shall be brought in its own name as trustee of an express trust, and any recovery of judgment shall, after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, be for the ratable benefit of the Holders in respect of which such judgment has been recovered.

Section 6.11 Trustee May File Proofs of Claim. The Trustee is authorized to file such proofs of claim and other papers or documents as may be necessary or advisable to have the claims of the Trustee and the Holders allowed in any judicial proceedings relative to the Company, its creditors or its property and, unless prohibited by law or applicable regulations, will be entitled to collect, receive and distribute any money or other property payable or deliverable on any such claims, and any custodian in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee, and, in the event that the Trustee consents to the making of such payments directly to the Holders, to pay to the Trustee any amount due to it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.06 of the Base Indenture. To the extent that the payment of any such compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.06 of the Base Indenture out of the estate in any such proceeding, will be denied for any reason, payment of the same will be secured by a lien on, and is paid out of, any and all distributions, dividends, money, securities and other properties that the Holders may be entitled to receive in such proceeding, whether in liquidation or under any plan of reorganization or arrangement or otherwise. Nothing herein contained will be deemed to authorize the Trustee to authorize or consent to, or to accept or to adopt on behalf of any Holder, any plan of reorganization, arrangement, adjustment or composition affecting the Securities or the rights of any Holder, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding.

Section 6.12 Restoration of Rights and Remedies. If the Trustee or any Holder has instituted any proceeding to enforce any right or remedy under this Indenture and such proceeding has been discontinued or abandoned for any reason, or has been determined adversely to the Trustee or to such Holder, then and in every such case, subject to any determination in such proceeding, the Company, the Trustee and the Holders shall be restored severally and respectively to their former positions hereunder and thereafter all rights and remedies of the Trustee and the Holders shall continue as though no such proceeding had been instituted.

Section 6.13 Rights and Remedies Cumulative. Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities in Section 2.07 of the Base Indenture, no right or remedy herein conferred

36

upon or reserved to the Trustee or to the Holders is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy.

Section 6.14 Delay or Omission Not a Waiver. No delay or omission of the Trustee or of any Holder to exercise any right or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein. Every right and remedy given by this Article 6 or by law to the Trustee or to the Holders may be exercised from time to time and as often as may be deemed expedient by the Trustee (subject to the limitations contained in this Indenture) or by the Holders, as the case may be.

Section 6.15 Priorities. If the Trustee collects any money pursuant to this Article 6, it will pay out the money in the following order:

FIRST: to the Trustee, its agents and attorneys for amounts due under Section 7.06 of the Base Indenture, including payment of all compensation, expenses and liabilities incurred, and all advances made, by the Trustee and the costs and expenses of collection;

SECOND: to the Holders, for any amounts due and unpaid on the principal of, accrued and unpaid interest on, Fundamental Change Purchase Price for, and any cash due upon conversion of, any Security, without preference or priority of any kind, according to such amounts due and payable on all of the Securities; and

THIRD: the balance, if any, to the Company or to such other party as a court of competent jurisdiction directs.

The Trustee may fix a record date and payment date for any payment to the Holders pursuant to this Section 6.15. If the Trustee so fixes a record date and a payment date, at least 15 days prior to such record date, the Company will deliver to each Holder and the Trustee a written notice, which notice will state such record date, such payment date and the amount of such payment.

Section 6.16 Undertaking for Costs. All parties to this Indenture agree, and each Holder, by such Holder’s acceptance of a Security, shall be deemed to have agreed, that any court may in its discretion require, in any suit for the enforcement of any right or remedy under this Indenture, or in any suit against the Trustee for any action taken or omitted by it as Trustee, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit, and that such court may in its discretion assess reasonable costs, including reasonable attorneys’ fees, against any party litigant in such suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant; provided, however, that the provisions of this Section 6.16 shall not apply to any suit instituted by the Trustee, to any suit instituted by any Holder, or group of Holders, holding in the aggregate more than 10% in aggregate principal amount of the Securities then Outstanding, or to any suit instituted by any Holder for the enforcement of the payment of the principal of, accrued and unpaid interest, if any, on, or Fundamental Change Purchase Price for, any Security on or after the due date expressed or provided for in this Indenture or to any suit for the enforcement of the right to convert any Security in accordance with the provisions of Article 4 hereof.

Section 6.17 Waiver of Stay, Extension and Usury Laws. The Company covenants that, to the extent that it may lawfully do so, it will not at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension or usury law wherever enacted, now or at any time hereafter in force, that may affect the covenants or the performance of this Indenture; and the Company, to the extent that it may lawfully do so, hereby expressly waives all benefit or advantage of any such law, and covenants that it will not, by resort to any such law, hinder, delay or impede the execution of any power herein granted to the Trustee, but will instead suffer and permit the execution of every such power as though no such law has been enacted.

Section 6.18 Notices from the Trustee. Notwithstanding anything to the contrary in the Base Indenture, whenever a Default occurs and is continuing and is known to the Trustee, the Trustee must deliver notice of such Default to the Holders within 90 days after the date on which such Default first occurred. Except in the case of a Default in the payment of the principal of, interest on, or Fundamental Change Purchase Price for, any Security or of a Default in the payment or delivery, as the case may be, of the consideration due upon conversion of a Security, the Trustee shall be protected in withholding such notice if and so long as the board of directors, the executive committee or a trust committee of directors and/or Responsible Officers of the Trustee in good faith determine that the withholding of such notice is in the interests of the Holders.

ARTICLE 7

SATISFACTION AND DISCHARGE

Section 7.01 Inapplicability of Provisions of Base Indenture; Satisfaction and Discharge of the Indenture. Article XI of the Base Indenture shall not apply with respect to the Securities. The provisions set forth in this Article 7 shall, with respect to the Securities, supersede in their entirety Article XI of the Base Indenture. The references to Section 11.05 in Section 4.03(c) and Section 7.05 of the Base Indenture are, with respect to the Securities, hereby deemed replaced by a reference to Section 7.03 hereof.

When (a) the Company shall deliver to the Security Registrar for cancellation all Securities theretofore authenticated (other than any Securities that have been destroyed, lost or stolen and in lieu of or in substitution for which other Securities shall have been authenticated and delivered) and not theretofore canceled, or (b) all the Securities not theretofore canceled or delivered to the Trustee for cancellation shall have become due and payable (whether on the Maturity Date, on any Fundamental Change Purchase Date, upon conversion or otherwise) and the Company shall deposit with the Trustee, in trust, or deliver to the Holders, as applicable, an amount of cash or the combination of cash and shares of Common Stock, if any, as the case may be (solely to settle amounts due with respect to outstanding conversions), sufficient to pay all amounts due on all of such Securities (other than any Securities that shall have been mutilated, destroyed, lost or stolen and in lieu of or in substitution for which other Securities shall have been authenticated and delivered) not theretofore canceled or delivered to the Trustee for cancellation, including principal and interest due, accompanied, except in the event the Securities are due and payable solely in cash at the Maturity Date or upon an earlier Fundamental Change Purchase Date, by a verification report as to the sufficiency of the deposited amount from a firm of nationally recognized independent certified accountants or other financial professionals, and if the Company shall also pay or cause to be paid all other sums payable hereunder by the Company, then this Indenture shall cease to be of further effect (except as to (i) rights hereunder of Holders to receive all amounts owing upon the Securities and the other rights, duties and obligations of Holders, as beneficiaries hereof with respect to the amounts, if any, so deposited with the Trustee and (ii) the rights, obligations and immunities of the Trustee hereunder), and the Trustee, on written demand of the Company accompanied by an Officers’ Certificate and an Opinion of Counsel and at the cost and expense of the Company, shall execute proper instruments acknowledging satisfaction and discharge of this Indenture; the Company, however, hereby agrees to reimburse the Trustee for any costs or expenses thereafter reasonably and properly incurred by the Trustee, including the fees and expenses of its counsel, and to compensate the Trustee for any services thereafter reasonably and properly rendered by the Trustee in connection with this Indenture or the Securities.

Section 7.02 Deposited Monies to Be Held in Trust by Trustee. Subject to Section 7.04 hereof, all monies and shares of Common Stock, if any, deposited with the Trustee pursuant to Section 7.01 hereof shall be held in trust for the sole benefit of the Holders of the Securities, and such monies and shares of Common Stock shall be applied by the Trustee to the payment, either directly or through any Paying Agent (including the Company if acting as its own Paying Agent), to the Holders of the particular Securities for the payment or settlement of which such monies or shares of Common Stock have been deposited with the Trustee, of all sums or amounts due and to become due thereon for principal and interest, if any.

Section 7.03 Paying Agent to Repay Monies Held. Upon the satisfaction and discharge of this Indenture, all monies and shares of Common Stock, if any, then held by any Paying Agent (if other than the Trustee) shall, upon written request of the Company, be repaid to it or paid to the Trustee, and thereupon such Paying Agent shall be released from all further liability with respect to such monies and shares of Common Stock.

Section 7.04 Return of Unclaimed Monies. Subject to the requirements of applicable law, any monies and shares of Common Stock deposited with or paid to the Trustee for payment of the principal of or interest, if any, on the Securities and not applied but remaining unclaimed by the Holders of the Securities for two years after the date upon which the principal of or interest, if any, on such Securities, as the case may be, shall have become due and payable, shall be repaid to the Company by the Trustee on demand, and all liability of the Trustee shall thereupon cease with respect to such monies and shares of Common Stock; and the Holder shall thereafter look only to the Company for any payment or delivery that such Holder may be entitled to collect unless an applicable abandoned property law designates another person.

Section 7.05 Reinstatement. If the Trustee or the Paying Agent is unable to apply any money or shares of Common Stock in accordance with Section 7.02 by reason of any order or judgment of any court or governmental authority enjoining,

38

restraining or otherwise prohibiting such application, the Company’s obligations under the Indenture and the Securities shall be revived and reinstated as though no deposit had occurred pursuant to Section 7.01 until such time as the Trustee or the Paying Agent is permitted to apply all such money and shares of Common Stock in accordance with Section 7.02; provided, however, that if the Company makes any payment of interest on, principal of or payment or delivery in respect of any Security following the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Securities to receive such payment from the money or shares of Common Stock, if any, held by the Trustee or Paying Agent.

ARTICLE 8

SUPPLEMENTAL INDENTURES

Section 8.01 Supplemental Indentures Without Consent of Holders. Section 9.01 of the Base Indenture shall not apply with respect to the Securities, and this Section 8.01 shall replace Section 9.01 of the Base Indenture in its entirety.

Without the consent of any Holder, the Company (when authorized by a Board Resolution) and the Trustee, at any time and from time to time, may enter into one or more indentures supplemental hereto, in form satisfactory to the Trustee, for any of the following purposes:

(a) to cure any ambiguity, defect or inconsistency under this Indenture or the Securities;

(b) to evidence the succession by a successor company and to provide for the assumption by a successor company of the Company’s obligations under this Indenture as set forth in Article X of the Base Indenture;

(c) to add to the Company’s covenants, restrictions, conditions or provisions for the benefit of the Holders of all or any Outstanding Securities;

(d) to add any additional Events of Default for the benefit of the Holders of all or any Outstanding Securities;

(i) to conform the text of the Indenture or the Securities to the “Description of the Notes” section of the Prospectus Supplement and the “Description of Debt Securities” section of the accompanying Prospectus.

Section 8.02 Supplemental Indentures With Consent of Holders. Section 9.02 of the Base Indenture shall not apply with respect to the Securities, and this Section 8.02 shall replace Section 9.02 of the Base Indenture in its entirety.

With the consent of the Holders of not less than a majority in principal amount of the Outstanding Securities affected by such supplemental indenture, including without limitation, consents obtained in connection with a purchase of, or tender or exchange offer for, Securities and by Act of said Holders delivered to the Company and the Trustee, the Company, when authorized by a Board Resolution, and the Trustee may enter into an indenture or indentures supplemental hereto for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of this Indenture or of modifying in any manner the rights of the Holders under this Indenture; provided, however, that no such supplemental indenture shall, without the consent of the Holder of each Outstanding Security affected thereby:

(a) extend the fixed maturity of the Securities;

39

(b) reduce the principal amount, reduce the rate of or extend the time of payment of interest of any Securities;

(c) change any of the Company’s obligations to pay Additional Amounts;

(d) reduce the amount of principal payable upon acceleration of the maturity of the Securities;

(e) change the currency in which the Securities or any interest thereon is payable;

(i) make any change to the rank or seniority of the Securities in a manner that is adverse to the rights of the Holders of the Securities; or

(k) reduce the requirements contained in this Indenture for quorum or voting; or

(l) modify any of the above provisions.

It shall not be necessary for any Act or consent of Holders under this Section 8.02 to approve the particular form of any proposed supplemental indenture, but it shall be sufficient if such Act or consent shall approve the substance thereof. The Company may, but shall not be obligated to, fix a record date for the purpose of determining the Persons entitled to consent to any indenture supplemental hereto. If a record date is fixed, the Holders on such record date, or their duly designated proxies, and only such Persons, shall be entitled to consent to such supplemental indenture, whether or not such Holders remain Holders after such record date; provided that, unless such consent shall have become effective by virtue of the requisite percentage having been obtained prior to the date which is 90 days after such record date, any such consent previously given shall automatically and without further action by any Holder be cancelled and of no further effect.

Section 8.03 Notice of Amendment or Supplement. After an amendment or supplement under this Article 8 becomes effective, the Company shall send to the Holders a notice briefly describing such amendment or supplement. However, the failure to give such notice to all the Holders, or any defect in the notice, shall not impair or affect the validity of the amendment or supplement.

ARTICLE 9

Section 9.04 Trust Indenture Act. If any provision hereof limits, qualifies or conflicts with a provision of the Trust Indenture Act that is required under such Act to be a part of and govern this Indenture, the latter provision shall control. If any provision of this Indenture modifies or excludes any provision of the Trust Indenture Act that may be so modified or excluded, the latter provision shall be deemed to apply to this Indenture as so modified or to be excluded, as the case may be.

Section 9.05 Benefits of Supplemental Indenture. Notwithstanding anything to the contrary in Section 2.09 of the Base Indenture, nothing in this Supplemental Indenture or in the Securities, expressed or implied, will give to any Person, other than the parties hereto, any Paying Agent, any Conversion Agent, any Authenticating Agent, any Security Registrar or their successors hereunder or the Holders of the Securities, any benefit or any legal or equitable right, remedy or claim under this Supplemental Indenture.

BLACKSTONE MORTGAGE TRUST, INC.

4.375% Convertible Senior Notes due 2022

This Security is one of a duly authorized issue of securities of the Company (herein called the “Securities”), issued under a Senior Debt Indenture dated as of November 25, 2013 (herein called the “Base Indenture”), and as further supplemented by the Second Supplemental Indenture, dated as of May 5, 2017 (herein called the “Supplemental Indenture” and the Base Indenture, as supplemented by the Supplemental Indenture, the “Indenture”) by and between the Company and The Bank of New York Mellon Trust Company, N.A., herein called the “Trustee”, and reference is hereby made to the Indenture for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. This Security is not subject to redemption at the option of the Company prior to the Maturity Date and does not benefit from a sinking fund.

As provided in and subject to the provisions of the Indenture, upon the occurrence of a Fundamental Change, the Holder of this Security will have the right, at such Holder’s option, to require the Company to purchase this Security, or any portion of this Security such that the principal amount of this Security that is not purchased equals $1,000 or an integral multiple of $1,000 in excess thereof, on the Fundamental Change Purchase Date at a price equal to the Fundamental Change Purchase Price for such Fundamental Change Purchase Date.

As provided in and subject to the provisions of the Indenture, the Holder hereof has the right, at its option (i) during certain periods and upon the occurrence of certain conditions specified in the Indenture, prior to the Close of Business on the Business Day immediately preceding February 1, 2022, and (ii) on or after February 1, 2022, at any time prior to the Close of Business on the second Scheduled Trading Day immediately preceding the Stated Maturity, to convert this Security or a portion of this Security such that the principal amount of this Security that is not converted equals $1,000 or an integral multiple of $1,000 in excess thereof, into an amount of cash, shares of Common Stock or a combination of cash and shares of Common Stock, as the case may be, determined in accordance with Article 4 of the Supplemental Indenture.

As provided in and subject to the provisions of the Indenture, the Company will make all payments in respect of the Fundamental Change Purchase Price for, and the principal amount of, this Security to the Holder that surrenders this Security to the Paying Agent to collect such payments in respect of this Security. The Company will pay cash amounts in money of the United States that at the time of payment is legal tender for payment of public and private debts.

The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities to be effected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of a majority in principal amount of the Securities at the time Outstanding. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities at the time Outstanding, on behalf of the Holders of all Securities, to waive compliance by the Company with certain provisions of the Indenture and certain past Defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.

As provided in and subject to the provisions of the Indenture, the Holder of this Security shall not have the right to institute any proceeding with respect to the Indenture, or for the appointment of a receiver or trustee, or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to the Security, the Holders of not less than 25% in principal amount of the Securities at the time Outstanding shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee indemnity satisfactory to it, and the Trustee shall not have received from the Holders of a majority in principal amount of Securities at the time Outstanding a direction inconsistent with such request, and shall have failed to institute any such proceeding, for 60 days after receipt of such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted by the Holder of this Security for the enforcement of any payment of principal hereof or interest hereon or amounts due upon conversion on or after the respective due dates expressed herein.

No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay or deliver, as the case may be, the principal of (including the

Fundamental Change Purchase Price), interest on and the amount of cash, shares of Common Stock or combination of cash and shares of Common Stock, as the case may be, due upon conversion of, this Security at the time, place and rate, and in the coin and currency, herein prescribed.

As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Security is registrable in the Register, upon surrender of this Security for registration of transfer at the office or agency of the Company in any place where the principal of and interest on this Security are payable, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by, the Holder hereof or its attorney duly authorized in writing, and thereupon one or more new Securities of this series and of like tenor, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees.

The Securities are issuable only in registered form without coupons in denominations of $1,000 and integral multiples of $1,000 in excess thereof. As provided in the Indenture and subject to certain limitations therein set forth, the Securities are exchangeable for a like aggregate principal amount of Securities and of like tenor of a different authorized denomination, as requested by the Holder surrendering the same.

Re: Registration Statement on Form S-3 (Registration No. 333-212769)

Ladies and Gentlemen:

We have served as Maryland counsel to Blackstone Mortgage Trust, Inc., a Maryland corporation (the “Company”), in connection with certain matters of Maryland law arising out of (a) the sale and issuance by the Company of up to $287,500,000 (including $37,500,000 which the underwriters in the offering have the option to purchase solely to cover over-allotments) in aggregate principal amount of the Company’s 4.375% Convertible Senior Notes due 2022 (the “Notes”) and (b) the issuance by the Company of up to 9,268,224 shares (the “Shares”) of the Company’s class A common stock, $0.01 par value per share (the “Common Stock”), that may be issuable upon conversion of the Notes, covered by the above-referenced Registration Statement, and all amendments thereto (collectively, the “Registration Statement”), filed by the Company with the United States Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended (the “1933 Act”).

In connection with our representation of the Company, and as a basis for the opinion hereinafter set forth, we have examined originals, or copies certified or otherwise identified to our satisfaction, of the following documents (hereinafter collectively referred to as the “Documents”):

1. The Registration Statement;

2. The Prospectus, dated July 29, 2016, as supplemented by a Prospectus Supplement, dated May 1, 2017 (the “Prospectus Supplement”), filed with the Commission pursuant to Rule 424(b) of the General Rules and Regulations promulgated under the 1933 Act;

3. The charter of the Company (the “Charter”), certified by the State Department of Assessments and Taxation of Maryland (the “SDAT”);

6. Resolutions adopted by the Board of Directors of the Company, and by a duly authorized committee thereof (the “Resolutions”), relating to, among other matters, (a) the sale and issuance of the Notes, (b) the Indenture (as defined herein) and (c) the issuance of the Shares upon conversion of the Notes, certified as of the date hereof by an officer of the Company;

7. The Indenture, dated as of November 25, 2013, as supplemented by one or more supplemental indentures (collectively, the “Indenture”), by and between the Company and The Bank of New York Mellon Trust Company, N.A., as trustee;

8. A certificate executed by an officer of the Company, dated as of the date hereof; and

In expressing the opinion set forth below, we have assumed the following:

1. Each individual executing any of the Documents, whether on behalf of such individual or another person, is legally competent to do so.

Each of the parties (other than the Company) executing any of the Documents has duly and validly executed and delivered each of the Documents to which such party is a signatory, and such party’s obligations set forth therein are legal, valid and binding and are enforceable in accordance with all stated terms.

4. All Documents submitted to us as originals are authentic. The form and content of all Documents submitted to us as unexecuted drafts do not differ in any respect relevant to this opinion from the form and content of such Documents as executed and delivered. All Documents submitted to us as certified or photostatic copies conform to the original documents. All signatures on all Documents are genuine. All public records reviewed or relied upon by us or on our behalf are true and complete. All representations, warranties, statements and information contained in the Documents are true and complete.

5. Upon the issuance of any of the Shares, the total number of shares of Common Stock issued and outstanding will not exceed the total number of shares of Common Stock that the Company is then authorized to issue under the Charter.

6. The Shares will not be issued or transferred in violation of the restrictions or limitations contained in Article VII of the Charter.

7. The Notes will be converted for the Shares in accordance with the terms of the Indenture and the Registration Statement.

The phrase “known to us” is limited to the actual knowledge, without independent inquiry, of the lawyers at our firm who have performed legal services in connection with the issuance of this opinion.

Based upon the foregoing, and subject to the assumptions, limitations and qualifications stated herein, it is our opinion that:

1. The Company is a corporation duly incorporated and validly existing under the laws of the State of Maryland and is in good standing with the SDAT.

2. The Company has the corporate power to enter into and perform its obligations under the Indenture. The Indenture has been duly authorized, executed and, so far as is known to us, delivered by the Company.

3. The issuance of the Notes has been duly authorized by all necessary corporate action on the part of the Company.

4. The issuance of the Shares upon conversion of the Notes has been duly authorized and, when and if issued and delivered upon conversion of the Notes in accordance with the terms thereof, the Registration Statement, the Indenture and the Resolutions, such Shares will be validly issued, fully paid and nonassessable.

The foregoing opinion is limited to the laws of the State of Maryland and we do not express any opinion herein concerning any other law. We express no opinion as to the applicability or effect of federal or state securities laws, including the securities laws of the State of Maryland, or as to federal or state laws regarding fraudulent transfers. We note that the Indenture is governed by the laws of the State of New York. To the extent that any matter as to which our opinion is expressed herein would be governed by the laws of any jurisdiction other than the State of Maryland, we do not express any opinion on such matter. The opinion expressed herein is subject to the effect of any judicial decision which may permit the introduction of parol evidence to modify the terms or the interpretation of agreements.

Ladies and Gentlemen:

We have acted as counsel to Blackstone Mortgage Trust, Inc., a Maryland corporation (the “Company”) in connection with the Registration Statement on Form S-3 (File No. 333-212769) (the “Registration Statement”) filed by the Company with the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended (the “Securities Act”), relating to the issuance by the Company of up to $287,500,000 aggregate principal amount of 4.375% Convertible Senior Notes due 2022 (the “Securities”). The Securities will be convertible into cash, shares of class A common stock, par value $0.01 per share, of the Company, or a combination thereof, pursuant to the terms of the Securities and an indenture, dated as of November 25, 2013 (the “Base Indenture”), as supplemented by the Second Supplemental Indenture, dated as of May 5, 2017 (the “Second Supplemental Indenture” and, together with the Base Indenture, the “Indenture”), each between the Company and The Bank of New York Mellon Trust Company, N.A., as trustee (the “Trustee”).

Blackstone Mortgage Trust, Inc. -2- May 5, 2017

We have examined the Registration Statement, the Base Indenture, a form of which has been filed with the Commission as an exhibit to the Registration Statement, the Second Supplemental Indenture, which is being filed with the Commission on the date hereof, a duplicate of the global note representing the Securities and the Underwriting Agreement, dated May 1, 2017 (the “Underwriting Agreement”), among the Company, BXMT Advisors L.L.C., a Delaware limited liability company and the several underwriters named therein. We also have examined the originals, or duplicates or certified or conformed copies, of such records, agreements, documents and other instruments and have made such other investigations as we have deemed relevant and necessary in connection with the opinion hereinafter set forth. As to questions of fact material to this opinion, we have relied upon certificates or comparable documents of public officials and of officers and representatives of the Company.

In rendering the opinion set forth below, we have assumed the genuineness of all signatures, the legal capacity of natural persons, the authenticity of all documents submitted to us as originals, the conformity to original documents of all documents submitted to us as duplicates or certified or conformed copies and the authenticity of the originals of such latter documents. We also have assumed that the Indenture is the valid and legally binding obligation of the Trustee.

We have assumed further that (1) the Company is validly existing and in good standing under the law of the State of Maryland and has duly authorized, executed and delivered or issued, as applicable, the Indenture and the Securities in accordance with the Company’s charter and by-laws and the law of the State of Maryland and (2) the execution, delivery, issuance and

Blackstone Mortgage Trust, Inc. -3- May 5, 2017

performance, as applicable, by the Company of the Indenture and the Securities do not and will not violate the law of the State of Maryland or any other jurisdiction (except that no such assumption is made with respect to the law of the State of New York and the federal law of the United States).

Based upon the foregoing, and subject to the qualifications, assumptions and limitations stated herein, we are of the opinion that, assuming due authentication thereof by the Trustee and upon payment and delivery in accordance with the Underwriting Agreement, the Securities will constitute valid and legally binding obligations of the Company enforceable against the Company in accordance with their terms.

Our opinion set forth above is subject to (i) the effects of bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and other similar laws relating to or affecting creditors’ rights generally, (ii) general equitable principles (whether considered in a proceeding in equity or at law), and (iii) an implied covenant of good faith and fair dealing. In addition, we express no opinion as to (A) the waiver of rights and defenses contained in Section 6.17 of the Second Supplemental Indenture or (B) the validity, legally binding effect or enforceability of Section 13.10 of the Base Indenture relating to the separability of provisions of the Indenture.

For purposes of our opinion, we assume that the increase in the Conversion Rate (as defined in the Indenture) upon the occurrence of a Make-Whole Fundamental Change (as defined in the Indenture) pursuant to the provisions of the Indenture and any related provisions of the Securities represents reasonable compensation for the lost value of the Securities as the result of the occurrence of a Make-Whole Fundamental Change.

We do not express any opinion herein concerning any law other than the law of the State of New York and the federal law of the United States.

Blackstone Mortgage Trust, Inc. -4- May 5, 2017

We hereby consent to the filing of this opinion letter as Exhibit 5.2 to the Company’s Current Report on Form 8-K filed on May 5, 2017 and to the use of our name under the caption “Legal Matters” in the Prospectus relating to the Securities.

Ladies and Gentlemen:

We have acted as counsel to Blackstone Mortgage Trust, Inc., a Maryland corporation (the “Company”), and BXMT Advisors L.L.C., a Delaware limited liability company (the “Manager”), in connection with the Registration Statement on Form S-3 (File No. 333-212769) (the “Registration Statement”) filed by the Company with the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended (the “Securities Act”), and the issuance by the Company of up to $287,500,000 aggregate principal amount of 4.375% Convertible Senior Notes due 2022 (the “Notes”) registered under the Registration Statement. The Notes will be convertible into cash, shares of class A common stock, par value $0.01 per share, of the Company (the “Common Stock”), or a combination thereof, pursuant to the terms of the Notes and the Indenture (as defined below).

We have examined the Registration Statement, the Company’s prospectus dated July 29, 2016 (the “Base Prospectus”), as supplemented by the preliminary prospectus supplement dated May 1, 2017 (together with the Base Prospectus, the “Preliminary Prospectus”) and the prospectus supplement dated May 1, 2017 (together with the Base Prospectus, the “Prospectus”), each filed by the Company pursuant to Rule 424(b) of the rules and regulations of the Commission under the Securities Act, which pursuant to Form S-3 incorporate by reference the

Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2016, the Company’s Quarterly Report on Form 10-Q for the quarter ended March 31, 2017, the Company’s definitive proxy statement on Schedule 14A filed on April 21, 2017 (solely to the extent incorporated by reference into Part III of our Annual Report on Form 10-K for the year ended December 31, 2016) and the description of the Company’s Common Stock contained in the registration statement on Form 8-A/A filed on May 6, 2013, each as filed under the Securities Exchange Act of 1934, as amended; the pricing term sheet dated May 1, 2017 relating to the Notes filed by the Company as a free writing prospectus pursuant to Rule 433 of the rules and regulations of the Commission under the Securities Act (together with the Preliminary Prospectus, the “Pricing Disclosure Package”); the Indenture, dated as of November 25, 2013 (the “Base Indenture”), between the Company and The Bank of New York Mellon Trust Company, N.A., as trustee, as supplemented by the Second Supplemental Indenture, dated as of May 5, 2017 (together with the Base Indenture, the “Indenture”); a duplicate of the global note representing the Notes, and the Second Amended and Restated Management Agreement, dated as of October 23, 2014, between the Company and the Manager. In addition, we have examined, and have relied as to matters of fact upon, originals, or duplicates or certified or conformed copies, of such records, agreements, documents and other instruments and such certificates or comparable documents of public officials and of officers and representatives of the Company and the Manager and have made such other investigations, as we have deemed relevant and necessary in connection with the opinions hereinafter set forth.

In such examination, we have assumed the genuineness of all signatures, the legal capacity of natural persons, the authenticity of all documents submitted to us as originals, the conformity to original documents of all documents submitted to us as duplicates or certified or conformed copies and the authenticity of the originals of such latter documents.

Blackstone Mortgage Trust, Inc.		May 5, 2017

In rendering the opinion set forth below, we have also assumed the accuracy of the representations contained in the officer’s certificate, dated as of the date hereof, provided to us by the Company (the “Officer’s Certificate”). These representations generally relate to the operation and classification of the Company as a real estate investment trust (a “REIT”), as defined in Section 856 of the Internal Revenue Code of 1986, as amended (the “Code”). For purposes of rendering such opinion, we have also assumed that the Company has been organized and operated and will continue to be organized and operated in the manner described in the Officer’s Certificate, the Registration Statement, the Prospectus and the applicable organizational documents of the Company and that all terms and provisions of such documents have been and will continue to be complied with.

Based upon the foregoing, and subject to the qualifications, assumptions and limitations stated herein, we are of the opinion that:

1. Commencing with the taxable year ended December 31, 2008, the Company has been organized in conformity with the requirements for qualification as a REIT under the Code, and its actual and proposed method of operation as described in the Prospectus and as represented by the Company, has enabled it, and will continue to enable it, to meet the requirements for qualification and taxation as a REIT under the Code.

2. The statements made in each of the Pricing Disclosure Package and the Prospectus under the caption “Material United States Federal Income Tax Considerations,” insofar as they purport to constitute summaries of provisions of United States federal tax law and regulations or legal conclusions with respect thereto, constitute accurate summaries of the matters described therein in all material respects.

The opinion set forth above is based upon the Code, the Treasury regulations promulgated thereunder and other relevant authorities and law, all as in effect on the date hereof.

Blackstone Mortgage Trust, Inc.		May 5, 2017
	-4-

Consequently, future changes in the law may cause the tax treatment of the transactions referred to herein to be materially different from that described above. Future changes in the Company’s method of operation could likewise cause the tax treatment referred to herein to be materially different from that described above. Our opinion is not binding upon either the Internal Revenue Service or any court. Thus, no assurances can be given that a position taken in reliance on our opinion will not be challenged by the Internal Revenue Service or rejected by a court. Qualification of the Company as a REIT will depend upon the Company’s satisfaction, through actual annual operating results and other annual requirements, of the various qualification tests contained in the Code and related Treasury regulations. We do not undertake to monitor whether the Company will, in fact, through actual annual operating results, satisfy the various qualification tests for the taxable year ending December 31, 2017, or any subsequent taxable years. Accordingly, no assurance can be given that the actual results of the Company’s operations for any particular taxable year will satisfy the tests necessary to qualify as or to be taxed as a REIT under the Code.

We do not express any opinion herein concerning any law other than the federal law of the United States.

We hereby consent to the filing of this opinion with the Commission as an exhibit to the Company’s Current Report on Form 8-K and to the reference to our firm under the heading “Legal Matters” in the Prospectus.
