the rights of Buyer against Seller and Pledgor and any collateral for any Obligations with respect to such payment; provided, that Guarantor shall not seek to enforce any right or receive any payment by way of subrogation until all amounts
due and payable by Seller or Pledgor to Buyer under the Transaction Documents or any related documents have been paid in full; provided, further, that such subrogation rights shall be subordinate in all respects to all amounts owing to
Buyer under the Transaction Documents. 
 4. Amendments, etc. with Respect to the Obligations. Guarantor shall remain obligated
hereunder notwithstanding that, without any reservation of rights against Guarantor, and without notice to or further assent by Guarantor, any demand for payment of any of the Obligations made by Buyer may be rescinded by Buyer and any of the
Obligations continued, and the Obligations, or the liability of any other party upon or for any part thereof, or any collateral security or guarantee therefor or right of offset with respect thereto, may, from time to time, in whole or in part, be
renewed, extended, amended, modified, accelerated, compromised, waived, surrendered or released by Buyer and any Transaction Document and any other document in connection therewith may be amended, modified, supplemented or terminated, in whole or in
part, as Buyer may deem advisable from time to time, and any collateral security, guarantee or right of offset at any time held by Buyer for the payment of the Obligations may be sold, exchanged, waived, surrendered or released. Buyer shall have no
obligation to protect, secure, perfect or insure any lien at any time held by it as security for the Obligations or for this Guaranty or any property subject thereto. When making any demand hereunder against Guarantor, Buyer may, but shall be under
no obligation to, make a similar demand on Seller or any other Person, and any failure by Buyer to make any such demand or to collect any payments from Seller or any such other Person or any release of Seller or such other Person shall not relieve
Guarantor of its Obligations or liabilities hereunder, and shall not impair or affect the rights and remedies, express or implied, or as a matter of law, of Buyer against Guarantor. For the purposes hereof “demand” shall include the
commencement and continuance of any legal proceedings. 
 5. Guaranty Absolute and Unconditional. (a) Guarantor hereby agrees
that its obligations under this Guaranty constitute a guarantee of payment when due and not of collection. Guarantor waives any and all notice of the creation, renewal, extension or accrual of any of the Obligations and notice of or proof of
reliance by Buyer upon this Guaranty or acceptance of this Guaranty; the Obligations, and any of them, shall conclusively be deemed to have been created, contracted or incurred in reliance upon this Guaranty; and all dealings between Seller and
Guarantor, on the one hand, and Buyer, on the other hand, shall likewise be conclusively presumed to have been had or consummated in reliance upon this Guaranty. Guarantor waives promptness, diligence, presentment, protest, demand for payment and
notice of default or nonpayment to or upon Seller or the Guaranty with respect to the Obligations. This Guaranty shall be construed as a continuing, absolute and unconditional guarantee of payment without regard to (i) the validity, regularity
or enforceability of any agreement, any of the Obligations or any collateral security therefor or guarantee or right of offset with respect thereto at any time or from time to time held by Buyer, (ii) any defense,
set-off or counterclaim (other than a defense of payment or performance) which may at any time be available to or be asserted by Seller against Buyer, (iii) any requirement that Buyer exhaust any right to
take any action against Seller or any other Person prior to or contemporaneously with proceeding to exercise any 












 
right against Guarantor under this Guaranty or (iv) any other circumstance whatsoever (with or without notice to or knowledge of Seller and Guarantor) which constitutes, or might be
construed to constitute, an equitable or legal discharge of Seller for the Obligations or of Guarantor under this Guaranty, in bankruptcy or in any other instance. When pursuing its rights and remedies hereunder against Guarantor, Buyer may, but
shall be under no obligation, to pursue such rights and remedies that Buyer may have against Seller or any other Person or against any collateral security or guarantee for the Obligations or any right of offset with respect thereto, and any failure
by Buyer to pursue such other rights or remedies or to collect any payments from Seller or any such other Person or to realize upon any such collateral security or guarantee or to exercise any such right of offset, or any release of Seller or any
such other Person or any such collateral security, guarantee or right of offset, shall not relieve Guarantor of any liability hereunder, and shall not impair or affect the rights and remedies, whether express, implied or available as a matter of
law, of Buyer against Guarantor. This Guaranty shall remain in full force and effect and be binding in accordance with and to the extent of its terms upon Guarantor and its successors and assigns thereof, and shall inure to the benefit of Buyer and
its permitted successors, endorsees, transferees and assigns, until all the Obligations and the obligations of Guarantor under this Guaranty shall have been satisfied by payment in full. 

(b) Without limiting the generality of the foregoing, Guarantor hereby agrees, acknowledges, and represents and warrants to Buyer as follows:

 (i) Guarantor hereby waives any defense arising by reason of, and any and all right to assert against Buyer any claim or defense based
upon, an election of remedies by Buyer which in any manner impairs, affects, reduces, releases, destroys and/or extinguishes Guarantor’s subrogation rights, rights to proceed against Seller or any other guarantor for reimbursement or
contribution, and/or any other rights of Guarantor to proceed against Seller, any other guarantor or any other person or security. 
 (ii)
Guarantor is presently informed of the financial condition of Seller and of all other circumstances which diligent inquiry would reveal and which bear upon the risk of nonpayment of the Obligations. Guarantor hereby covenants that it will make its
own investigation and will continue to keep itself informed about the financial condition of Seller, the status of other guarantor, if any, of all other circumstances which bear upon the risk of nonpayment and that it will continue to rely upon
sources other than Buyer for such information and will not rely upon Buyer for any such information. Absent a written request for such information by Guarantor to Buyer, Guarantor hereby waives the right, if any, to require Buyer to disclose to
Guarantor any information which Buyer may now or hereafter acquire concerning such condition or circumstances including, but not limited to, the release of or revocation by any other guarantor. 

(iii) Guarantor has independently reviewed the Transaction Documents and related agreements and has made an independent determination as to the
validity and enforceability thereof, and in executing and delivering this Guaranty to Buyer, Guarantor is not in any manner relying upon the validity, and/or enforceability, and/or attachment, and/or perfection of any liens or security interests of
any kind or nature granted by Seller or any other guarantor to Buyer, now or at any time and from time to time in the future. 












 6. Reinstatement. This Guaranty shall continue to be effective, or be reinstated, as
the case may be, if at any time payment, or any part thereof, of any of the Obligations is rescinded or must otherwise be restored or returned by Buyer upon the insolvency, bankruptcy, dissolution, liquidation or reorganization of Seller or upon or
as a result of the appointment of a receiver, intervenor or conservator of, or trustee or similar officer for Seller or any substantial part of the property of Seller, or otherwise, all as though such payments had not been made. 

7. Payments. Guarantor hereby agrees that the Obligations will be paid to Buyer, without
set-off or counterclaim in United States Dollars at the address specified in writing by Buyer.

interest of Guarantor, whether now or hereafter outstanding, or make any other distribution in respect thereof, either directly or indirectly, whether in cash or property or in obligations of Guarantor; provided that, so long as no monetary Event of
Default referenced in Section 14(a)(i), (ii), (iv) or (v) of the Repurchase Agreement in an amount equal to or greater than $500,000 shall have occurred and be continuing, Claros Mortgage Trust, Inc. may distribute the minimum amount of

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 Buyer to or for the credit or the account of Guarantor, or any part thereof in such amounts
as Buyer may elect, against and on account of the obligations and liabilities of Guarantor to Buyer hereunder and claims of every nature and description of Buyer against Guarantor, in any currency, arising under any Transaction Document, as Buyer
may elect, whether or not Buyer has made any demand for payment and although such obligations, liabilities and claims may be contingent or unmatured. Buyer shall notify Guarantor promptly of any such set-off
and the application made by Buyer, provided that the failure to give such notice shall not affect the validity of such set-off and application. The rights of Buyer under this
Section 11 are in addition to other rights and remedies (including, without limitation, other rights of set-off) that the Buyer may have. 

12. Severability. Any provision of this Guaranty which is prohibited or unenforceable in any jurisdiction shall, as to such
jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable
such provision in any other jurisdiction. 
 13. Section Headings. The section headings used in this Guaranty are for convenience of
reference only and are not to affect the construction hereof or be taken into consideration in the interpretation hereof. 
 14. No
Waiver; Cumulative Remedies. Buyer shall not by any act (except by a written instrument pursuant to Section 15 hereof), delay, indulgence, omission or otherwise be deemed to have waived any right or remedy hereunder or
to have acquiesced in any default or event of default or in any breach of any of the terms and conditions hereof. No failure to exercise, nor any delay in exercising, on the part of Buyer, any right, power or privilege hereunder shall operate as a
waiver thereof. No single or partial exercise of any right, power or 












 
privilege hereunder shall preclude any other or further exercise thereof or the exercise of any other right, power or privilege. A waiver by Buyer of any right or remedy hereunder on any one
occasion shall not be construed as a bar to any right or remedy which Buyer would otherwise have on any future occasion. The rights and remedies herein provided are cumulative, may be exercised singly or concurrently and are not exclusive of any
rights or remedies provided by law. 
 15. Waivers and Amendments; Successors and Assigns; Governing Law. None of the terms or
provisions of this Guaranty may be waived, amended, supplemented or otherwise modified except by a written instrument executed by Guarantor and Buyer. This Guaranty shall be binding upon the heirs, personal representatives, successors and assigns of
Guarantor and shall inure to the benefit of Buyer, and their respective successors and permitted assigns. THIS GUARANTY SHALL BE GOVERNED BY, AND CONSTRUED AND INTERPRETED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK PURSUANT TO SECTIONS
5-1401 AND 5-1402 OF THE NEW YORK GENERAL OBLIGATIONS LAW WITHOUT GIVING EFFECT TO THE CONFLICT OF LAW PRINCIPLES THEREOF. 

16. Notices. Unless otherwise provided in this Agreement, all notices, consents, approvals and requests required or permitted hereunder
shall be given in writing and shall be effective for all purposes if hand delivered or sent by (a) hand delivery, with proof of delivery, (b) certified or registered United States mail, postage prepaid, (c) expedited prepaid delivery
service, either commercial or United States Postal Service, with proof of delivery or (d) by telecopier (with answerback acknowledged) or e-mail provided that such telecopied or e-mailed notice must also be delivered by one of the means set forth above, to the address specified below or at such other address and person as shall be designated from time to time by any party hereto, as the
case may be, in a written notice to the other parties hereto in the manner provided for in this Section 16. A notice shall be deemed to have been given: (w) in the case of hand delivery, at the time of delivery,
(x) in the case of registered or certified mail, when delivered or the first attempted delivery on a Business Day, (y) in the case of expedited prepaid delivery upon the first attempted delivery on a Business Day, or (z) in the case

RIGHT TO SUE IN ANY OTHER JURISDICTION. 
 18. Integration. This Guaranty represents the agreement of Guarantor with respect to the
subject matter hereof and there are no promises or representations by Buyer relative to the subject matter hereof not reflected herein. 

19. Counterparts. This Guaranty may be executed in counterparts, each of which so executed shall be deemed to be an original, but all
of such counterparts shall together constitute but one and the same instrument. Delivery by telecopier or other electronic transmission (including a .pdf e-mail transmission) of an executed counterpart of a
signature page to this Guaranty shall be effective as delivery of an original executed counterpart of this Guaranty. 
 20.
Acknowledgments. Guarantor hereby acknowledges that: 
 (a) Guarantor has been advised by counsel in the negotiation, execution and
delivery of this Guaranty and the related documents; 
 (b) Buyer does not have any fiduciary relationship to Guarantor, and the
relationship between Buyer, on the one hand, and Guarantor, on the other, is solely that of creditor and surety; and 
 (c) no joint venture
exists between or among any of Buyer, Guarantor and/or Seller. 
 21. Intent. Guarantor intends for this Guaranty to be a credit
