NOW THEREFORE, in consideration of the mutual covenants and agreements contained herein and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto hereby agree to the above recitals and as follows:

1.    Confirmation and Reaffirmation. Guarantor hereby consents to all modifications of the Existing Credit Agreement agreed to in connection with the execution and delivery by Borrower of the Credit Agreement, the other Loan Documents delivered in connection therewith and the transactions contemplated thereby. Guarantor acknowledges and agrees that the Guaranty: (i) is full force and effect, (ii) constitutes the legal, valid, and binding obligation of Guarantor, (iii) has not been modified or amended, and Guarantor further agrees that (iv) there are no understandings or agreements, written or oral, relating to the Guaranty other than the Guaranty itself, and (v) Administrative Agent and Lenders are not in default under the Loan Documents.

3.    Amendment to Guaranty.    The Guaranty is hereby amended as follows:

(a)    The definition of “Guarantor’s Share” appearing in Section 1 of the Guaranty is hereby deleted in its entirety and replaced with the following:

““Guarantor’s Share” as used herein, means a sum equal to, as of any date of determination, fifty percent (50%) of the Guaranteed Obligations on such date of determination.”

(b)    Section 22 of the Guaranty is hereby deleted in its entirety and replaced with the following:

“Section 22. SEVERAL OBLIGATIONS. THE MACERICH PARTNERSHIP, L.P., A DELAWARE LIMITED PARTNERSHIP (“OTHER GUARANTOR”) EXECUTED AND DELIVERED THAT CERTAIN AMENDED AND RESTATED REPAYMENT GUARANTY, DATED AS OF DECEMBER 10, 2020, IN FAVOR

2

OF ADMINISTRATIVE AGENT, FOR ITS BENEFIT AND FOR THE BENEFIT OF THE OTHER LENDERS (AS THE SAME MAY BE FURTHER AMENDED, RESTATED, SUPPLEMENTED, REPLACED OR OTHERWISE MODIFIED FROM TIME TO TIME, THE “OTHER GUARANTY”), PURSUANT TO WHICH OTHER GUARANTOR HAS GUARANTEED THE PAYMENT AND PERFORMANCE OF A PORTION OF THE GUARANTEED OBLIGATIONS AS DESCRIBED THEREIN. THE OBLIGATIONS OF GUARANTOR UNDER THIS GUARANTY AND OTHER GUARANTOR UNDER THE OTHER GUARANTY SHALL BE SEVERAL AND NOT JOINT. NOTWITHSTANDING ANYTHING TO THE CONTRARY UNDER ANY LOAN DOCUMENT, GUARANTOR SHALL NOT BE LIABLE FOR, AND GUARANTIED PARTIES SHALL NOT EXERCISE ANY REMEDIES AGAINST GUARANTOR, FOR MORE THAN ITS GUARANTOR’S SHARE OF THE GUARANTEED OBLIGATIONS.”

4.    Independent Obligations; Exercise of Remedies. Notwithstanding anything to the contrary contained in the Guaranty, Guarantor acknowledges and agrees that, as consideration for the modifications to the Existing Credit Agreement, Guarantor shall be liable for payment of the Guaranteed Obligations, and Administrative Agent shall be entitled to make demand therefor, at any time that an Event of Default (as defined below) exists, notwithstanding that an “Event of Default” (as defined in the Credit Agreement) has not occurred. The calculation of Guarantor’s liability hereunder during an Event of Default (as defined below) when an “Event of Default” (as defined in the Credit Agreement) does not exist shall be calculated as if the underlying indebtedness of the Borrower had been accelerated. Guarantor acknowledges and agrees that its payment obligations hereunder are independent and absolute, and are not contingent on any “Event of Default” of the Borrower existing under the Credit Agreement.

“Event of Default” means the occurrence of any of the following, whatever the reason for such event and whether it shall be voluntary or involuntary or be effected by operation of Applicable Law or pursuant to any judgment or order of any Governmental Authority, and in each case, following the expiration of the applicable notice and cure periods:

(i)    an Event of Default (as defined in the Credit Agreement),

(ii)    any Pledgor shall fail to perform or observe any term, covenant, condition or agreement on its part to be performed or observed and contained in this Agreement,

(iii)     Guarantor shall fail to perform or observe any term, covenant, condition or agreement on its part to be performed or observed and contained in either the Guaranty or the PREIT Non-Recourse Carve-Out Guaranty; or

(iv)    an Event of Default by a PREIT Loan Party (as defined in the Credit Agreement) under Section 10.4 of the Credit Agreement.

5.    References. All reference to the “Credit Agreement” and “Loan Documents” in the Guaranty shall be deemed hereafter to refer to the Credit Agreement and the Loan Documents as set forth in the recitals
