EXHIBIT 10.12

UNFUNDED OBLIGATIONS GUARANTY

THIS UNFUNDED OBLIGATIONS GUARANTY (“Guaranty”) is made this 21^st day of September, 2018, by BROOKFIELD DTLA HOLDINGS LLC, a Delaware limited liability company (the “Guarantor”), in favor of CITIBANK, N.A., as administrative agent for Lenders (defined below) (in such capacity, together with its successors, transferees and assigns, the “Administrative Agent”) and each of the Lenders.

RECITALS:

A.Administrative Agent, certain lenders that are a party thereto (collectively, together with their respective successors and/or assigns, “Lenders”), Citigroup Global Markets Inc. and Natixis, New York Branch, collectively, as joint lead arranger and NORTH TOWER, LLC, a Delaware limited liability company (“Borrower”) have entered into a certain Loan Agreement (as it may hereafter be modified, supplemented, extended, or renewed and in effect from time to time, the “Loan Agreement”), which Loan Agreement sets forth the terms and conditions of a loan (said loan, together with all advances which may hereafter be made pursuant to the Loan Agreement, being referred to herein as the “Loan”) to Borrower secured by certain Property as defined and more particularly described in the Loan Agreement.

B.    Guarantor is an Affiliate of Borrower and will receive direct or indirect benefit from Lenders’ making of the Loan to Borrower.

C.    The Loan is evidenced by certain promissory notes executed by Borrower and payable to the order of the Lender named therein (such promissory notes, as the same may hereafter each be renewed, extended, supplemented, increased or modified and in effect from time to time, and all other notes given in substitution therefor, or in modification, renewal, or extension thereof, in whole or in part, are herein collectively called the “Note”).

D.    Any capitalized term used and not defined in this Guaranty shall have the meaning given to such term in the Loan Agreement. This Guaranty is one of the Loan Documents described in the Loan Agreement.

NOW, THEREFORE, for good and valuable consideration, the receipt and adequacy of which are hereby acknowledged, and as a material inducement to Lenders to make the Loan to Borrower, Guarantor hereby guarantees to Administrative Agent and Lenders the prompt and full payment and performance of the Guaranteed Obligations (defined below) upon the following terms and conditions:

1.    Guaranteed Obligations. Guarantor hereby unconditionally and irrevocably guarantees to Administrative Agent for the benefit of Lenders the punctual payment equal to the Guaranteed Obligations (hereinafter defined). As used herein, the term “Guaranteed Obligations” shall mean a portion of the Debt equal to the lesser of (i) the Remaining Unfunded Obligations, less (a) the Unfunded Obligations Funds and (b) any payments made under any Mezzanine Unfunded Obligations Guaranty in respect of the “Guaranteed Obligations” thereunder and (ii) the then-outstanding balance of the Debt. As used in this Section 1, the term

“Mezzanine Unfunded Obligations Guaranty” means (i) the Unfunded Obligations Guaranty (as defined in the Mezzanine A Loan Agreement) and (ii) the Unfunded Obligations Guaranty (as defined in the Mezzanine B Loan Agreement).

2.    Certain Agreements and Waivers by Guarantor.

(a)    Guarantor hereby agrees that each of the following shall constitute Events of Default: (i) the occurrence of a default by Guarantor in payment of the Guaranteed Obligations, or any part thereof, when such indebtedness becomes due and (ii) subject to the cure rights contained in Section 10.1(f) of the Loan Agreement, the dissolution, bankruptcy and/or insolvency of any Guarantor.

(b)    Guarantor shall, upon written demand, pay the Guaranteed Obligations to Administrative Agent for the Benefit of Lenders from time to time. It shall not be necessary for Administrative Agent, in order to enforce such payment, first to (i) institute suit or pursue or exhaust any rights or remedies against Borrower or others liable for the Debt, (ii) enforce any rights against any security that shall ever have been given to secure the Debt, (iii) join Borrower or any others liable for the payment or performance of the Guaranteed Obligations or any part thereof in any action to enforce this Guaranty and/or (iv) resort to any other means of obtaining payment or performance of the Guaranteed Obligations.

(c)    Suit may be brought or demand may be made against all parties who have signed this Guaranty or any other guaranty covering all or any part of the Guaranteed Obligations, or against any one or more of them, separately or together, without impairing the rights of Administrative Agent and/or Lender against any party hereto.

(d)    In the event any payment of any Guaranteed Obligation by Borrower or any other Person to Administrative Agent for the benefit of Lenders is held to constitute a preference, fraudulent transfer or other voidable payment under any bankruptcy, insolvency or similar law, or if for any other reason Administrative Agent and/or Lenders are required to refund such payment or pay the amount thereof to any other party, such payment by Borrower or any other party to Administrative Agent for the benefit of Lenders shall not constitute a release of Guarantor from any liability hereunder and this Guaranty shall continue to be effective or shall be reinstated (notwithstanding any prior release, surrender or discharge by Lender of this Guaranty or of Guarantor), as the case may be, with respect to, and this Guaranty shall apply to, any and all amounts so refunded by Administrative Agent and/or any Lender or paid by Administrative Agent and/or any Lender to another Person (which amounts shall constitute part of the Guaranteed Obligations). If acceleration of the time for payment by Borrower of any Guaranteed Obligation under any Loan Document is stayed or delayed by any law or tribunal, any amounts due and payable hereunder shall nonetheless be payable by Guarantor upon written demand by Administrative Agent.

3.    Subordination. If, for any reason whatsoever, Borrower is now or hereafter becomes indebted to Guarantor:

(a)    such indebtedness and all interest thereon and all liens, security interests and rights now or hereafter existing with respect to property of Borrower securing same shall, at all

- 2 -

times, be subordinate in all respects to the Guaranteed Obligations and to all liens, security interests and rights now or hereafter existing to secure the Guaranteed Obligations;

(b)    Guarantor shall not be entitled to enforce or receive payment, directly or indirectly, of any such indebtedness of Borrower to Guarantor until the Debt has been fully and finally paid and performed;

(c)    Guarantor hereby assigns and grants to Administrative Agent for the benefit of Lenders a security interest in all such indebtedness and security therefor, if any, of Borrower to Guarantor now existing or hereafter arising during the term of this Guaranty, including any dividends and payments pursuant to debtor relief or insolvency proceedings referred to below. In the event of receivership, bankruptcy, reorganization, arrangement or other debtor relief or insolvency proceedings involving Borrower as debtor, Administrative Agent on behalf of Lenders shall have the right to prove its claim in any such proceeding so as to establish its rights hereunder and shall have the right to receive directly from the receiver, trustee or other custodian (whether or not an Event of Default shall have occurred or be continuing under any of the Loan Documents), dividends and payments that are payable upon any obligation of Borrower to Guarantor now existing or hereafter arising, and to have all benefits of any security therefor, until the Debt has been indefeasibly paid in full. If, notwithstanding the foregoing provisions, Guarantor should receive any payment, claim or distribution that is prohibited as provided above in this Section, Guarantor shall promptly pay the same to Administrative Agent for the benefit of Lenders, Guarantor hereby agreeing that it shall receive the payment, claim or distribution in trust for Administrative Agent for the benefit of Lenders and shall have absolutely no dominion over the same except to pay it promptly to Administrative Agent for the benefit of Lenders; provided, however, that the foregoing shall not restrict distributions by Borrower to equity owners of Borrower (including Guarantor), in the ordinary course of business and operations of the Property provided no Trigger Period exists; and

(d)    Guarantor shall promptly upon request of Administrative Agent from time to time execute such documents and perform such acts as Administrative Agent may reasonably require to evidence and perfect its interest and to permit or facilitate exercise of its rights under this Section.

4.    Other Liability of Guarantor or Borrower. If Guarantor is or becomes liable, by endorsement or otherwise, for any indebtedness owing by Borrower to Administrative Agent for the benefit of Lenders other than under this Guaranty, such liability shall not be in any manner impaired or affected hereby, and the rights of Administrative Agent and Lenders hereunder shall be cumulative of any and all other rights that Administrative Agent and Lenders may have against Guarantor.

5.    Assignment by Administrative Agent and Lenders. This Guaranty is for the benefit of Administrative Agent and Lenders and Administrative Agent’s and Lenders’ successors and permitted assigns, and in the event of an assignment of the Loan and the Loan Documents, or any part thereof, the rights and benefits hereunder may be transferred with such assignment (and only as part of such assignment). Guarantor waives notice of any transfer or assignment of the Loan or the Loan Documents, or any part thereof, and agrees that failure to give notice will not affect the liabilities of Guarantor hereunder.

6.    Binding Effect. This Guaranty is binding not only on Guarantor, but also on Guarantor’s heirs, personal representatives, successors and assigns. Upon the death of Guarantor, if Guarantor is a natural person, this Guaranty shall continue against Guarantor’s estate as to all of the Guaranteed Obligations, including that portion incurred or arising after the death of Guarantor and shall be provable in full against Guarantor’s estate, whether or not the Guaranteed Obligations are then due and payable. If this Guaranty is signed by more than one Person, then all of the obligations of Guarantor arising hereunder shall be jointly and severally binding on each of the undersigned, and their respective heirs, personal representatives, successors and assigns, and the term “Guarantor” shall mean all of such Persons and each of them individually. Without limitation of any other term, provision or waiver contained herein, Guarantor hereby acknowledges and agrees that it has been furnished true, complete and correct copies of the Loan Documents and has reviewed the terms and provisions thereof (including, without limitation, the Guaranteed Obligations).

7.    Nature of Guaranty. Guarantor hereby acknowledges and agrees that this Guaranty (a) is a guaranty of payment and not only of collection and that Guarantor is liable hereunder as a primary obligor, (b) shall only be deemed discharged after the indefeasible satisfaction in full of the Debt, (c) shall not be reduced, released, discharged, satisfied or otherwise impacted in connection with (i) any act or occurrence that might, but for the provisions hereof, be deemed a legal or equitable reduction, satisfaction, discharge or release and/or (ii) Administrative Agent’s and/or Lender’s enforcement of remedies under the Loan Documents and (d) shall survive the foregoing and shall not merge with any resulting foreclosure deed, deed in lieu or similar instrument (if any).

8.    Governing Law. The governing law and related provisions set forth in Section 17.2 of the Loan Agreement (including, without limitation, any authorized agent provisions thereof) are hereby incorporated by reference as if fully set forth herein (with Guarantor substituted in all places where Borrower appears thereunder) and shall be deemed fully applicable to Guarantor hereunder. Guarantor hereby certifies that it has received and reviewed the Loan Agreement (including, without limitation, Section 17.2 thereof). In the event of any conflict or inconsistency between the terms and conditions hereof and this Section 8, this Section 8 shall control.

9.    Invalidity of Certain Provisions. If any provision of this Guaranty or the application thereof to any Person or circumstance shall, for any reason and to any extent, be declared to be invalid or unenforceable, neither the remaining provisions of this Guaranty nor the application of such provision to any other Person or circumstance shall be affected thereby, and the remaining provisions of this Guaranty, or the applicability of such provision to other Persons or circumstances, as applicable, shall remain in effect and be enforceable to the maximum extent permitted by applicable Legal Requirements.

10.    Attorneys’ Fees, Costs and Expenses of Collection. Guarantor shall pay within ten (10) Business Days after written demand all reasonable attorneys’ fees for outside counsel and all other out-of-pocket costs and expenses incurred by Administrative Agent and/or Lenders in the enforcement of or preservation of Administrative Agent’s and/or Lenders’ rights under this Guaranty including, without limitation, all reasonable attorneys’ fees for outside counsel, out-of-pocket costs and expenses, investigation costs, and all court costs, whether or not suit is filed

- 4 -

herein, or whether at maturity or by acceleration, or whether before or after maturity, or whether in connection with bankruptcy, insolvency or appeal, or whether in connection with the collection and enforcement of this Guaranty against any other Guarantor, if there be more than one. Guarantor agrees to pay interest on any expenses or other sums due to Administrative Agent and/or Lenders under this Section 10 that are not paid within ten (10) Business Days of demand on Guarantor, at a rate per annum equal to the Interest Rate and accruing from and after the date that is ten (10) Business Days from demand on Guarantor. Guarantor’s obligations and liabilities under this Section 10 shall survive any payment or discharge in full of the Debt.

11.    Payments. All sums payable under this Guaranty shall be paid in lawful money of the United States of America that at the time of payment is legal tender for the payment of public and private debts.

12.    Controlling Agreement. It is not the intention of Administrative Agent, Lenders or Guarantor to obligate Guarantor to pay interest in excess of that lawfully permitted to be paid by Guarantor under applicable Legal Requirements. Should it be determined that any portion of the Guaranteed Obligations or any other amount payable by Guarantor under this Guaranty constitutes interest in excess of the maximum amount of interest that Guarantor, in Guarantor’s capacity as guarantor, may lawfully be required to pay under applicable Legal Requirements, the obligation of Guarantor to pay such interest shall automatically be limited to the payment thereof in the maximum amount so permitted under applicable Legal Requirements. The provisions of this Section shall override and control all other provisions of this Guaranty and of any other agreement between Guarantor, Administrative Agent and Lenders.

13.    Notices. Any and all notices, elections, demands, requests and responses thereto permitted or required to be given under this Guaranty shall be given in accordance with the applicable terms and conditions of the Loan Agreement. Notices to Guarantor shall be addressed as follows:

14.    Cumulative Rights. The exercise by Administrative Agent on behalf of Lenders of any right or remedy hereunder or under any other Loan Document, or at law or in equity, shall not preclude the concurrent or subsequent exercise of any other right or remedy. Administrative Agent and Lenders shall have all rights, remedies and recourses afforded to Administrative Agent and Lenders by reason of this Guaranty or any other Loan Document or by law or equity or otherwise, and the same (a) shall be cumulative and concurrent, (b) may be pursued

- 5 -

separately, successively or concurrently against Guarantor or others obligated for the Guaranteed Obligations, or any part thereof, or against any one or more of them, or against any security or otherwise, at the sole discretion of Administrative Agent, (c) may be exercised as often as occasion therefor shall arise, it being agreed by Guarantor that the exercise of, discontinuance of the exercise of or failure to exercise any of such rights, remedies, or recourses shall in no event be construed as a waiver or release thereof or of any other right, remedy, or recourse, and (d) are intended to be, and shall be, nonexclusive. No waiver of any default on the part of Guarantor or of any breach of any of the provisions of this Guaranty or of any other document shall be considered a waiver of any other or subsequent default or breach, and no delay or omission in exercising or enforcing the rights and powers granted herein or in any other document shall be construed as a waiver of such rights and powers, and no exercise or enforcement of any rights or powers hereunder or under any other document shall be held to exhaust such rights and powers, and every such right and power may be exercised from time to time. The granting of any consent, approval or waiver by Administrative Agent and/or Lenders shall be limited to the specific instance and purpose therefor and shall not constitute consent or approval in any other instance or for any other purpose. No notice to or demand on Guarantor in any case shall of itself entitle Guarantor to any other or further notice or demand in similar or other circumstances. No provision of this Guaranty or any right, remedy or recourse of Administrative Agent on behalf of Lenders with respect hereto, or any default or breach, can be waived, nor can this Guaranty or Guarantor be released or discharged in any way or to any extent, except specifically in each case by a writing intended for that purpose (and which refers specifically to this Guaranty) executed, and delivered to Guarantor, by Administrative Agent and/or Lenders.

15.    Subrogation. Notwithstanding anything to the contrary contained herein, (a) Guarantor shall not have any right of subrogation in or under any of the Loan Documents or to participate in any way therein, or in any right, title or interest in and to any security or right of recourse for the Guaranteed Obligations, until indefeasible payment in full of the Debt, and (b) if Guarantor is or becomes an “insider” (as defined in Section 101 of the Bankruptcy Code) with respect to Borrower, then Guarantor hereby irrevocably and absolutely waives any and all rights of contribution, indemnification, reimbursement or any similar rights against Borrower with respect to this Guaranty (including any right of subrogation, except to the extent of collateral held by Administrative Agent for the benefit of Lenders), whether such rights arise under an express or implied contract or by operation of law. It is the intention of the parties that Guarantor shall not be deemed to be a “creditor” (as defined in Section 101 of the Bankruptcy Code) of Borrower by reason of the existence of this Guaranty in the event that Borrower or Guarantor becomes a debtor in any proceeding under the Bankruptcy Code. This waiver is given to induce Lenders to make the Loan to Borrower.

16.    Further Assurances. Guarantor at Guarantor’s expense will promptly execute and deliver to Administrative Agent all such other and further documents, agreements, and instruments in compliance with or accomplishment of the agreements of Guarantor under this Guaranty reasonably requested by Administrative Agent, so long as Guarantor’s obligations are not increased and its rights are not decreased, in each case, other than to a de minimis extent.

17.    No Fiduciary Relationship. The relationship between Administrative Agent, Lenders and Guarantor is solely that of lender and guarantor. Neither Administrative Agent nor Lenders have a fiduciary or other special relationship with or duty to Guarantor and none is

- 6 -

created hereby or may be inferred from any course of dealing or act or omission of Administrative Agent and/or Lenders.

18.    Interpretation. If this Guaranty is signed by more than one Person as “Guarantor”, then the term “Guarantor” as used in this Guaranty shall refer to all such Persons jointly and severally, and all promises, agreements, covenants, waivers, consents, representations, warranties and other provisions in this Guaranty are made by and shall be binding upon each and every such undersigned Person, jointly and severally and Administrative Agent on behalf of Lenders may pursue any Guarantor hereunder without being required (i) to pursue any other Guarantor hereunder or (ii) pursue rights and remedies under the Security Instruments and/or applicable Legal Requirements with respect to the Property or any other Loan Documents.

19.    Time of Essence. Time shall be of the essence in this Guaranty with respect to all of Guarantor’s obligations hereunder.

20.    Execution. This Guaranty may be executed in multiple counterparts, each of which, for all purposes, shall be deemed an original, and all of which together shall constitute one and the same agreement.

21.    Entire Agreement. This Guaranty embodies the entire agreement between Administrative Agent, Lenders and Guarantor with respect to the guaranty by Guarantor of the Guaranteed Obligations. This Guaranty supersedes all prior agreements and understandings, if any, with respect to guaranty by Guarantor of the Guaranteed Obligations. No condition or conditions precedent to the effectiveness of this Guaranty exist. This Guaranty shall be effective upon execution by Guarantor and delivery to Administrative Agent. This Guaranty may not be modified, amended or superseded except in a writing signed by Administrative Agent (acting at the direction of Lenders) and Guarantor. The Loan Documents represent the final agreement between the parties and may not be contradicted by evidence of prior, contemporaneous or subsequent oral agreements of the parties.

22.    WAIVER OF JURY TRIAL. GUARANTOR, ADMINISTRATIVE AGENT AND LENDERS, HEREBY WAIVE, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, THE RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM, WHETHER IN CONTRACT, TORT OR OTHERWISE, RELATING DIRECTLY OR INDIRECTLY TO THE LOAN, THE APPLICATION FOR THE LOAN, THIS GUARANTY, THE NOTE, THE SECURITY INSTRUMENT OR THE OTHER LOAN DOCUMENTS OR ANY ACTS OR OMISSIONS OF ADMINISTRATIVE AGENT, ANY LENDER OR GUARANTOR.

23.    Consent to Jurisdiction. Guarantor, Administrative Agent and the Lender each irrevocably submits generally and unconditionally for itself and in respect of its property to the nonexclusive jurisdiction of any state or federal court sitting in the State of New York over any suit, action or proceeding arising out of, or relating to, this Guaranty, and irrevocably agrees that all claims in respect of such action or proceeding may be heard and determined in such state or federal court. Guarantor, Administrative Agent and the Lender each irrevocably waives, to the fullest extent permitted by law, any objection that they may now or hereafter have to the laying

- 7 -

of venue of any such suit, action or proceeding brought in any such court, and any claims that any such suit, action or proceeding is brought in an inconvenient forum. Final judgment in any such suit, action or proceeding brought in any such court shall be conclusive and binding upon each such party and may be enforced in any court in which they are subject to jurisdiction, by a suit upon such judgment provided that service of process is effected upon Guarantor as provided in the Loan Documents or as otherwise permitted by applicable Legal Requirements. Guarantor hereby releases, to the extent permitted by applicable Legal Requirements, all errors and all rights of exemption, appeal, stay of execution, inquisition, and other rights to which Guarantor may otherwise be entitled under the laws of the United States of America or of any state of possession of the United States of America now in force and which may hereinafter be enacted. The authority and power to appear for and enter judgment against Guarantor shall not be exhausted by one or more exercises thereof or by any imperfect exercise thereof and shall not be extinguished by any judgment entered pursuant thereto. Such authority may be exercised on one or more occasions or from time to time in the same or different jurisdiction as often as Administrative Agent shall deem necessary and desirable, for all of which this Guaranty shall be sufficient warrant.

24.    Waivers.

28.    Set-Off. In addition to any rights and remedies of Administrative Agent and Lenders provided by this Guaranty and by law, Administrative Agent and Lenders shall have the right in their sole discretion, without prior notice to Guarantor, any such notice being expressly waived by Guarantor to the extent permitted by applicable law, upon any amount becoming due and payable by Guarantor hereunder (whether at the stated maturity, by acceleration or otherwise), to set-off and appropriate and apply against such amount any and all deposits (general or special, time or demand, provisional or final), in any currency, and any other credits, indebtedness or claims, in any currency, in each case whether direct or indirect, absolute or contingent, matured or unmatured, at any time held or owing by Administrative Agent and/or Lenders or any Affiliate thereof to or for the credit or the account of Guarantor; provided, however, Administrative Agent and/or Lenders may only exercise such right during the continuance of an Event of Default. Administrative Agent and Lenders agree promptly to notify Guarantor after any such set-off and application made by Administrative Agent and/or a Lender; provided that the failure to give such notice shall not affect the validity of such set-off and application.

29.    Termination. This Guaranty shall terminate upon the earlier of (i) the date that the Debt has been indefeasibly paid in full, and there has expired the maximum possible period thereafter during which any payment made by Borrower or others to Lender with respect to the Loan could be deemed a preference under the Bankruptcy Code and (ii) the date when the Remaining Unfunded Obligations have been reduced to zero.
