A.The Grantee is a key employee of the Company or one of its Subsidiaries or affiliates and provides services to the Partnership.

B.Pursuant to its Long-Term Incentive Plan (“LTIP”) the Company can award equity interests of the Company or the Partnership, including shares of the Company’s Common Stock, Stock Units and units of limited partnership interest of the Partnership designated as “LTIP Units” in the Partnership Agreement (as defined herein) under The Macerich Company 2003 Equity Incentive Plan, as amended (the “2003 Plan”), either as standalone awards or as alternatives among which the award recipient can elect, to provide certain key employees of the Company or its Subsidiaries and affiliates, including the Grantee, in connection with their employment with the long-term incentive compensation described in this Award Agreement (this “Agreement” or “Award Agreement”), and thereby provide additional incentive for them to promote the progress and success of the business of the Company and its Subsidiaries and affiliates, including the Partnership, while increasing the total return to the Company’s stockholders. 2021 LTIP Units (PB) (as defined herein) have been awarded by the Compensation Committee (the “Committee”) of the Board of Directors of the Company (the “Board”) pursuant to authority delegated to it by the Board as set forth in the Committee’s charter, including authority to make grants of equity interests in the Partnership which may, under certain circumstances, become exchangeable for shares of the Company’s Common Stock reserved for issuance under the 2003 Plan, or any successor equity plan (as any such plan may be amended, modified or supplemented from time to time, collectively the “Stock Plan”). This Agreement evidences an award to the Grantee under the LTIP (this “Award”), which is subject to the terms and conditions set forth herein.

C.The Grantee was selected by the Committee to receive this Award as one of a select group of highly compensated or management employees who, through the effective execution of their assigned duties and responsibilities, are in a position to have a direct and measurable impact on the Company’s long-term financial results. Effective as of the grant date specified in Schedule A hereto, the Committee awarded to the Grantee the number of 2021 LTIP Units (PB) (as defined herein) set forth in Schedule A.

(a)the assignment to the Grantee of any duties materially inconsistent in any respect with the Grantee’s position (including status, offices, titles and reporting requirements), authority, duties or responsibilities, or any other material diminution in such position, authority, duties or responsibilities (whether or not occurring solely as a result of the Company’s ceasing to be a publicly traded entity);

(e)any material breach by the Company of the Grantee’s Service Agreement (if one exists).

In the event that the Company fails to remedy the condition constituting Good Reason during the applicable Cure Period, the Grantee’s “separation from service” (within the meaning of Section 409A of the Code) must occur, if at all, within two years following the occurrence of such condition in order for such termination as a result of such condition to constitute a termination for Good Reason. If the Grantee suffers a Disability or dies following the occurrence of such material negative change in the employment relationship and the Grantee has given the Company the requisite written notice but the Company has failed to remedy the situation prior to such physical or mental incapacity or death, the Grantee’s physical or mental incapacity or death shall not affect the ability of the Grantee or his heirs or beneficiaries, as applicable, to treat the Grantee’s termination of employment as a termination for Good Reason, Retirement, death or Disability. For purposes of the definition of Good Reason, the term “Base Salary” means the annual base rate of compensation payable to Grantee by the Company prior to any reduction thereof, before deductions or voluntary deferrals authorized by the Grantee or required by law to be withheld from the Grantee by the Company.

during the Cumulative Performance Period it will remain a Peer REIT (such delisted business entities, “Delisted Peer REITs”).

“Peer REIT Total Return” means, (a) for a Peer REIT other than a Delisted Peer REIT, with respect to the Cumulative Performance Period, the absolute total stockholder return of the common equity of such Peer REIT during the Cumulative Performance Period, calculated in the same manner as Total Return is calculated for the Company and (b) for a Delisted Peer REIT, an absolute total stockholder return of -100%.

As set forth in, and pursuant to, Section 9 hereof, appropriate adjustments to the Total Return shall be made to take into account all stock dividends, stock splits, reverse stock splits and the other events set forth in Section 9 hereof that occur during the Cumulative Performance Period. In calculating Total Return, it is the current intention of the Committee to use total return to stockholders data for the Company and the Peer REITs available from one or more third party sources, though the Committee reserves the right in its reasonable discretion to retain the services of a consultant to analyze relevant data or perform necessary calculations for purposes of this Award. If the Committee delegates the calculation of Total Return to a valuation or other expert, including matters such as the determination of dividend reinvestment and the inclusion or exclusion of REITs as Peer REITs, the Committee is entitled to rely on such valuation or other expert.

(a)On the terms and conditions set forth in this Agreement, as well as the terms and conditions of the Stock Plan, the Grantee is hereby granted this Award consisting of the number of LTIP Units set forth on Schedule A hereto opposite “2021 LTIP Units (PB)”, which is incorporated herein by reference (the “2021 LTIP Units (PB)”).

(b)If pursuant to Section 4 hereof vesting above 100% of the 2021 LTIP Units (PB) occurs, an additional number of 2021 LTIP Units (PB) shall be granted to the Grantee

to cover the excess vesting percentage based on the calculations to be made pursuant to Section 4 hereof (the “2021-2 LTIP Units (PB)”) and issued under the Partnership Agreement effective as of the last day of the Cumulative Performance Period. In connection with any such subsequent grant of 2021-2 LTIP Units (PB) the Grantee shall execute and deliver to the Company and the Partnership such documents, comparable to the documents executed and delivered in connection with the Agreement, as the Company and/or the Partnership reasonably request in order to comply with all applicable legal requirements, including, without limitation, federal and state securities laws.

(c)If pursuant to Section 3(b) hereof 2021-2 LTIP Units (PB) are granted and issued to the Grantee, a payment in cash shall be made to the Grantee as soon as practicable after the time of such grant and issuance in an amount equal to (i) the total amount of all distributions paid with respect to one Unit between the date of grant of the 2021 LTIP Units (PB) and the LTIP Unit Distribution Participation Date provided in Section 7(a) multiplied by (ii) the number of 2021-2 LTIP Units (PB) granted and issued pursuant to Section 3(b) hereof.

(d)2021 LTIP Units (PB) shall constitute and be treated as the property of the Grantee as of the applicable grant date, subject to the terms of this Agreement and the Partnership Agreement. Every grant of 2021 LTIP Units (PB) to the Grantee pursuant to this Award shall be set forth in minutes of the meetings of the Committee. 2021 LTIP Units (PB) will be: (A) subject to vesting and/or forfeiture to the extent provided in Sections 4 and 5 hereof; and (B) subject to restrictions on transfer as provided in Section 8 hereof.

4.Vesting of 2021 LTIP Units (PB).

(a)The number of 2021 LTIP Units (PB) that will be earned pursuant to this Award will be based on the Company’s FFO and Year-End Permanent Occupancy for the 2021 Performance Period, 2022 Performance Period, 2023 Performance Period and the Cumulative Performance Period, subject to adjustment based on the percentile rank of the Company’s Total Return relative to the Peer REIT Total Return for the Peer REITs for the Cumulative Performance Period (the “Relative TSR Modifier”), as set forth below.

(b)Except as otherwise set forth in this Section 4 and Section 5 below, one-half of the 2021 LTIP Units (PB) shall be earned for the applicable performance period indicated below on the basis of the Company’s FFO performance relative to the “threshold,” “target,” and “maximum” levels indicated below in the percentages indicated below, and will become vested at the end of the Cumulative Performance Period (or at such other date as provided in Section 5 hereof):

* Percentage earned for performance below Threshold is zero, with linear interpolation for performance between Threshold and Target and between Target and Maximum.

As soon as practicable following each of the 2021 Performance Period, the 2022 Performance Period, the 2023 Performance Period and the Cumulative Performance Period, the Committee shall determine the Company’s FFO performance for such period. In the event that any of the 2021 Performance Period, the 2022 Performance Period or the 2023 Performance Period concludes (or does not commence) as a result of a Change of Control or the Company’s FFO performance for any such period cannot be determined, FFO shall be deemed to have been achieved at Target performance for any such performance period. In the event that the Cumulative Performance Period concludes as a result of a Change of Control, FFO shall be measured based on the Company’s actual performance from the beginning of the Cumulative Performance Period through the most recently completed fiscal year prior to the Change of Control for which the Company’s FFO performance can be determined and, for any fiscal year during the Cumulative Performance Period that is not completed or for which the Company’s FFO performance cannot be determined, the Company shall be deemed to have achieved Target FFO performance for such fiscal year.

(c)Except as otherwise set forth in this Section 4 and Section 5 below, one-half of the 2021 LTIP Units (PB) shall be earned for the applicable performance period indicated below on the basis of the Company’s Year-End Permanent Occupancy relative to the “threshold,” “target,” and “maximum” levels indicated below in the percentages indicated below, and will become vested at the end of the Cumulative Performance Period (or at such other date as provided in Section 5 hereof):

* Percentage earned for performance below Threshold is zero, with linear interpolation for performance between Threshold and Target and between Target and Maximum.

As soon as practicable following each of the 2021 Performance Period, the 2022 Performance Period and the 2023 Performance Period, the Committee shall determine the Company’s Year-

End Permanent Occupancy performance for such period. In the event that any of the foregoing performance periods concludes (or does not commence) as a result of a Change of Control or the Company’s Year-End Permanent Occupancy performance for any such period cannot be determined, Year-End Permanent Occupancy shall be deemed to have been achieved at Target performance for any such performance period.

(d)As soon as practicable following the conclusion of the Cumulative Performance Period, the number of earned 2021 LTIP Units (PB) determined pursuant to Sections 4(b) and (c) above will be modified by the Relative TSR Modifier as set forth below:

*Percentage earned modifier is subject to linear interpolation for performance between 25th and 50th percentiles and between 50th and 75th percentiles.

The percentile rank above shall be calculated using the following conventions:

Subject to Section 5 hereof, vesting of the Grantee’s 2021 LTIP Units (PB) shall occur as of the last day of the Cumulative Performance Period, provided that the Continuous Service of the Grantee continues through the last day of the Cumulative Performance Period, regardless of when the Committee completes its determination of FFO, Year-End Permanent Occupancy, percentile rank or any other calculations or assessments related to its determination of the vesting percentage. If, after giving effect to the Relative TSR Modifier, the percentage of the Grantee’s 2021 LTIP Unit (PB) that will become vested as of the end of the Cumulative Performance Period exceeds 100%, then 2021-2 LTIP Units (PB) shall be granted and issued as of the vesting date pursuant to Section 3(b) above shall be immediately vested upon such grant and issuance.

For the avoidance of doubt, assuming no Change of Control (i.e., the last day of the Cumulative Performance Period is December 31, 2023), the intent of this Section 4(d) is that (i) the Company’s Total Return will be calculated using as the first input the Share Price on December 31, 2020 and as the last input the Share Price on December 31, 2023, and (ii) each Peer REIT’s Total Return will be calculated in the same manner with respect to the common equity of each such Peer REIT.

(e)The Committee may, upon consideration of FFO, Year-End Permanent Occupancy and the statistical data for the Peer REITs relative to Peer REIT Total Return for the Cumulative Performance Period, exercise its reasonable discretion to allow for vesting of 2021 LTIP Units (PB) under Sections 4(b), (c) and (d) above on a basis other than strict mathematical calculations to the extent appropriate in light of the circumstances. By way of illustration, the foregoing would allow the Committee to provide for vesting to occur at a particular level if the Peer REIT Total Return of a number of Peer REITs is clustered within a narrow range such that the effect of the precise calculation of percentile rank would be that vesting would not occur or occur at a lower level. The Committee does not have the discretion to adjust downward the vesting of 2021 LTIP Units (PB).

(f)The Grantee agrees to provide Continuous Service to the Company in consideration for the conditional rights to the unvested 2021 LTIP Units (PB). Except as otherwise provided in Section 5 or pursuant to the Stock Plan, the vesting of the 2021 LTIP Units (PB) requires Continuous Service through the last day of the Cumulative Performance Period as a condition to the vesting of the 2021 LTIP Units (PB). Partial service, even if substantial, during any vesting period will not entitle the Grantee to any proportionate vesting or avoid or mitigate a termination of rights and benefits upon or following a termination of employment or service except as provided in Section 5 below or under the Stock Plan.

(g)Any 2021 LTIP Units (PB) that do not become vested pursuant to this Section 4 or Section 5 below shall, without payment of any consideration by the Partnership, automatically and without notice terminate, be forfeited and be and become null and void as of the end of the Cumulative Performance Period, and neither the Grantee nor any of his or her successors, heirs, assigns, or personal representatives will thereafter have any further rights or interests in such unvested 2021 LTIP Units (PB).

5.Change of Control or Termination of Grantee’s Service Relationship.

(a)If the Grantee is a party to a Service Agreement, the provisions of this Section 5 shall govern the vesting of the Grantee’s 2021 LTIP Units (PB) exclusively in the event of a Change of Control or termination of the Grantee’s service relationship with the Company or any Subsidiary or affiliate, unless the Service Agreement contains provisions that expressly refer to this Section 5 and provides that those provisions of the Service Agreement shall instead govern the vesting of the Grantee’s 2021 LTIP Units (PB). The foregoing sentence will be deemed an amendment to any applicable Service Agreement to the extent required to apply its terms consistently with this Section 5, such that, by way of illustration, any provisions of the Service Agreement with respect to accelerated vesting or payout of the Grantee’s bonus or incentive compensation awards in the event of certain types of terminations of Grantee’s service

relationship (such as, for example, termination at the end of the term, termination without Cause by the employer or termination for Good Reason by the employee) shall not (unless the Service Agreement contains provisions that expressly refer to this Section 5 and provides that those provisions of the Service Agreement shall instead govern the vesting of the Grantee’s 2021 LTIP Units (PB)) be interpreted as requiring that any calculations set forth in Section 4 hereof be performed, or vesting occur with respect to this Award other than as specifically provided in this Section 5. In the event an entity ceases to be a Subsidiary or affiliate of the Company, such action shall be deemed to be a termination of employment of all employees of that entity for purposes of this Agreement resulting in any then unvested 2021 LTIP Units (PB), without payment of any consideration by the Partnership, being automatically and without notice forfeited; provided that the Committee, in its sole and absolute discretion, may make provision in such circumstances for accelerated vesting of some or all of the Grantee’s remaining unvested 2021 LTIP Units (PB) that have not previously been forfeited and, if applicable, for the granting of 2021-2 LTIP Units (PB) effective immediately prior to such event.

(b)In the event of a Change of Control prior to December 31, 2023, then:

(i)the Cumulative Performance Period, and any of the 2021 Performance Period, 2022 Performance Period and 2023 Performance Period that had not previously concluded in the absence of the Change of Control shall end on such date and the calculations provided in Section 4 hereof shall be performed effective as of the date of the Change of Control and following the date of the Change of Control no further calculations pursuant to Section 4 hereof shall be performed with respect to the Grantee; and

(ii)if the 2021 LTIP Units (PB) remain outstanding after a Change of Control or equivalent replacement awards (as defined in Section 5(b)(iv) hereof) are substituted for the 2021 LTIP Units (PB) at the time of the Change of Control, then the number of 2021 LTIP Units (PB) that are determined as of the date of the Change of Control pursuant to the calculations provided in Section 4 shall remain subject to vesting tied to the Grantee’s Continuous Service until December 31, 2023 as if no Change of Control had occurred, except that the Grantee shall become fully vested in such 2021 LTIP Units (PB) immediately (A) upon the Grantee’s Qualified Termination in connection with or within twenty-four (24) months after the Change of Control, or (B) upon the Grantee’s death, Disability or Retirement;

(iii)if neither the 2021 LTIP Units (PB) remain outstanding after a Change of Control nor equivalent replacement awards (as defined in Section 5(b)(iv) hereof) are substituted for the 2021 LTIP Units (PB) at the time of the Change of Control, then the Grantee shall become fully vested in the number of 2021 LTIP Units (PB) that are determined pursuant to the calculations provided in Section 4 as of the date of the Change of Control; and

(iv)an award shall qualify as an “equivalent replacement award” if the following conditions are met in the good faith discretion of the Committee:

(A)the replacement award is of the same type as the 2021 LTIP Units (PB) being replaced, including, without limitation, income tax attributes relating to the extent and timing of recognition of taxable income, gain or loss by the Grantee;

(B)the replacement award has a value equal to the Fair Market Value of the 2021 LTIP Units being replaced as of the effective date of the Change of Control;

(C)the equity securities issuable upon the conversion, exercise, exchange or redemption of the replacement award, or securities underlying the replacement award, as applicable, are listed on a national stock exchange;

(D)the replacement award contains terms relating to vesting (including with respect to the Grantee’s Qualified Termination, death, Disability or Retirement) that are substantially identical to those of the 2021 LTIP Units (PB); and

(E)the other terms and conditions of the replacement award are not less favorable to the Grantee than the terms and conditions of the 2021 LTIP Units (PB).

(c)Except as otherwise provided in Section 5(b), in the event of the Grantee’s Qualified Termination, death or Disability or Retirement (as applicable below) prior to the end of the Cumulative Performance Period, conditioned (except in the case of death) upon the execution and delivery by the Grantee of a customary release of claims and covenant not to solicit employees of the Company or its Subsidiaries or Affiliates following termination, the Grantee will not forfeit the 2021 LTIP Units (PB) upon such event, but the following provisions of this Section 5(c) shall modify the determination of vesting for the Grantee, subject, in each case, to the provisions of Sections 6.4 and 6.5 of the Stock Plan:

(i)the calculations provided in Section 4 hereof shall be performed as of the end of the 2021 Performance Period, 2022 Performance Period, 2023 Performance Period and Cumulative Performance Period, to the extent not previously calculated prior to such Qualified Termination, death, Disability or Retirement, as if such Qualified Termination, death, Disability or Retirement (as applicable below) had not occurred, and, following such calculations, the Grantee shall become vested in the number of 2021 LTIP Units (PB) determined in accordance with this Section 5(c);

(ii)if the Grantee experiences a Retirement, death or Disability, in each case, prior to the first anniversary of the Effective Date, the number of 2021 LTIP Units (PB) resulting from the calculations provided in Section 4 hereof shall be multiplied by the Partial Service Factor (with the resulting number being rounded to the nearest whole LTIP Unit), and such adjusted number of 2021 LTIP Units (PB) shall become vested and any other 2021 LTIP Units (PB) that are not included in the foregoing calculation shall be immediately forfeited);

(iii)if the Grantee experiences a Retirement, death or Disability, in each case, on or after the first anniversary of the Effective Date, there will be no reduction in the number of 2021 LTIP Units (PB) resulting from the calculations provided in Section 4 hereof, and such unadjusted number of 2021 LTIP Units (PB) shall become vested; and

(iv)if the Grantee experiences a Qualified Termination prior to the end of the Cumulative Performance Period, the number of 2021 LTIP Units (PB) resulting from the calculations provided in Section 4 hereof with respect to any performance period that concluded after the date of the Qualified Termination shall be multiplied by the Qualified Termination Factor (with the resulting number being rounded to the nearest whole LTIP Unit), and such adjusted number of 2021 LTIP Units (PB) (plus the unadjusted number of 2021 LTIP Units (PB) resulting from the calculations provided in Section 4 hereof with respect to any performance period that concluded on or prior to the date of the Qualified Termination) shall become vested and any other 2021 LTIP Units (PB) that are not included in the foregoing calculation shall be immediately forfeited.

(d)If the Grantee becomes engaged in Competitive Activities at any time on or following the effective date of Retirement and before the end of the applicable Cumulative Performance Period, then the provisions relating to vesting due to Retirement under Section 5(b) or 5(c), as applicable, will not apply, and, upon the date the Grantee becomes engaged in any such Competitive Activities during such period, all 2021 LTIP Units (PB), except for those that, prior to such engagement in Competitive Activities, had previously been vested pursuant to Section 4 hereof during the Grantee’s Continuous Service or that otherwise became vested under this Section 5, shall automatically and immediately be forfeited by the Grantee. Any forfeited 2021 LTIP Units (PB) shall, without payment of any consideration by the Partnership, automatically and without notice be and become null and void, and neither the Grantee nor any of his successors, heirs, assigns, or personal representatives will thereafter have any further rights or interests in such forfeited 2021 LTIP Units (PB).

(e)If the Grantee’s employment with the Company or a Subsidiary or affiliate terminates as a result of a retirement under circumstances that do not meet the definition of “Retirement” under this Agreement, the Committee may, on a case-by-case basis and in its sole discretion, provide for accelerated or continued vesting of some or all of the Grantee’s unvested 2021 LTIP Units (PB) that have not previously been forfeited and, if applicable, for the granting of 2021-2 LTIP Units (PB), in each case effective prior to the effective date of retirement, but in any such event, the provisions of Section 5(d) will apply as if such retirement was deemed a “Retirement” for purposes of this Agreement, and any such vesting will be conditioned upon the execution and delivery by the Grantee of a customary release of claims and covenant not to solicit employees of the Company or its Subsidiaries or Affiliates following such termination.

(f)In the event of a termination of employment or other cessation of the Grantee’s Continuous Service prior to the end of the Cumulative Performance Period, effective as of the date of such termination or cessation, all 2021 LTIP Units (PB) except for those that had previously vested pursuant to Section 4 hereof and those that otherwise become vested or

will continue to vest pursuant to this Section 5 shall automatically and immediately be forfeited by the Grantee. Any forfeited 2021 LTIP Units (PB) shall, without payment of any consideration by the Partnership, automatically and without notice be and become null and void, and neither the Grantee nor any of his successors, heirs, assigns, or personal representatives will thereafter have any further rights or interests in such forfeited 2021 LTIP Units (PB).

6.Payments by Award Recipients. No amount shall be payable to the Company or the Partnership by the Grantee at any time in respect of this Award.

7.Distributions. Distributions on 2021 LTIP Units (PB) will be paid in accordance with the Partnership Agreement as modified hereby as follows:

(a)The LTIP Unit Distribution Participation Date (as defined in the Partnership Agreement) shall be (i) the date of grant, with respect to 10% of the 2021 LTIP Units (PB) issued pursuant to this Agreement, and (ii) the last day of the Cumulative Performance Period, with respect to all other 2021 LTIP Units (PB) issued pursuant to this Agreement (to the extent they became vested in accordance with Sections 4 and 5 hereof). Vested 2021 LTIP Units (PB) shall be entitled to receive the full distribution payable on Units outstanding as of the record date next following the last day of the Cumulative Performance Period, whether or not they will have been outstanding for the whole period.

(b)Prior to the last day of the Cumulative Performance Period, 2021 LTIP Units (PB) not otherwise forfeited in accordance with Section 4 or 5 hereof shall be entitled to receive 10% of regular periodic distributions payable to holders of Units (the “Current Distributions”) and 0% of special, extraordinary or other distributions made not in the ordinary course.

(c)An amount equal to (i) the difference between (x) all distributions (regular, special, extraordinary or otherwise) paid with respect to one Unit between the date of grant of the 2021 LTIP Units (PB) and the last day of the Cumulative Performance Period and (y) the Current Distributions paid with respect to one 2021 LTIP Unit up to the last day of the Cumulative Performance Period (such difference, the “Contingent Distributions”) multiplied by (ii) the number of 2021 LTIP Units (PB) shall be credited to a notional (unfunded) account for the benefit of the Grantee on the books and records of the Partnership subject to vesting. As promptly as practicable after the last day of the Cumulative Performance Period, an amount equal to the positive difference (if any) between (A) the Contingent Distributions that would have been paid with respect to those 2021 LTIP Units (PB) that have become vested pursuant to Sections 4 or 5 hereof and (B) if any, the Current Distributions paid to the Grantee prior to the last day of the Cumulative Performance Period in accordance with Section 7(b) in respect of the Unearned 2021 LTIP Units (PB) shall be paid to the Grantee. The “Unearned 2021 LTIP Units (PB)” means the number of 2021 LTIP Units (PB), if any, that are forfeited following vesting pursuant to Sections 4 or 5 hereof. Any portion of the notional account that is not payable to the Grantee shall be forfeited and revert to the Partnership free and clear of any claims by the Grantee.

(d)To the extent that the Partnership makes distributions to holders of Units partially in cash and partially in additional Units or other securities, unless the Committee in its sole discretion determines to allow the Grantee to make a different election, the Grantee shall be deemed to have elected with respect to all 2021 LTIP Units (PB) eligible to receive such distribution to receive 10% of such distribution in cash and 90% in Units, with the cash component constituting the Current Distribution prior to the last day of the Cumulative Performance Period.

(e)To the extent that the allocations of income, gain, loss and deduction actually reported on each Partner’s K-1 for any taxable year differ from the allocations that would have been made for such year if this Amendment has been in effect at such time, the Partnership shall adjust allocations for the current and future taxable periods in such manner as the General Partner deems appropriate to fully offset such difference. The intent of this Section 7(e) is to put each Partner as quickly as possible in the same position as he or she would have been in had this Amendment been in effect at all relevant times. This Section 7(e) shall be interpreted consistently with such intent.

8.Restrictions on Transfer. None of the 2021 LTIP Units (PB) shall be sold, assigned, transferred, pledged or otherwise disposed of or encumbered (whether voluntarily or involuntarily or by judgment, levy, attachment, garnishment or other legal or equitable proceeding) (each such action a “Transfer”), or redeemed in accordance with the Partnership Agreement (a) until the date that is one year after they have become vested pursuant to Section 4 or Section 5 other than in connection with a Change of Control, and (b) unless such Transfer is in compliance with all applicable securities laws (including, without limitation, the Securities Act of 1933, as amended (the “Securities Act”)), and such Transfer is in accordance with the applicable terms and conditions of the Partnership Agreement; provided, however, that clause (a) above shall not apply with respect to (i) the conversion into Units of 2021 LTIP Units (PB) that have become vested in accordance with Sections 4 or 5 hereof (“Converted LTIP Units”), but, for the avoidance of doubt, any such Converted LTIP Units may not be redeemed in accordance with the Partnership Agreement until the date that the restrictions in clause (a) above would cease to apply to the corresponding 2021 LTIP Units (PB) or (ii) any Transfer either of 2021 LTIP Units (PB) that have become vested in accordance with Sections 4 or 5 hereof or of Converted LTIP Units, so long as such Transfer is (A) permitted under the Partnership Agreement and (B) in connection with donative, estate or tax planning by the Grantee; and provided, further, that the Transferee agrees in writing with the Company and the Partnership not to make any further Transfer of such vested 2021 LTIP Units (PB) or Converted LTIP Units other than as permitted by this Section 8. In connection with any Transfer of 2021 LTIP Units (PB) or Converted LTIP Units, the Partnership may require the Grantee to provide an opinion of counsel, satisfactory to the Partnership, that such Transfer is in compliance with all federal and state securities laws (including, without limitation, the Securities Act). Any attempted Transfer of 2021 LTIP Units (PB) not in accordance with the terms and conditions of this Section 8 shall be null and void, and the Partnership shall not reflect on its records any change in record ownership of any 2021 LTIP Units (PB) as a result of any such Transfer, shall otherwise refuse to recognize any such Transfer and shall not in any way give effect to any such Transfer of any 2021 LTIP Units (PB). The restrictions on Transfer in this Section 8 shall not be interpreted to

prohibit the Grantee from designating one or more beneficiaries to receive the Grantee’s LTIP Units or Converted LTIP Units that are payable in the event of the Grantee’s death. Any such beneficiary designation shall be on a form provided or approved by the Company.

9.Changes in Capital Structure. Without duplication with the provisions of Section 6.2 of the Stock Plan, if (a) the Company shall at any time be involved in a merger, consolidation, dissolution, liquidation, reorganization, exchange of shares, sale of all or substantially all of the assets or stock of the Company, spin-off of a Subsidiary, business unit or significant portion of assets or other fundamental transaction similar thereto, (b) any stock dividend, stock split, reverse stock split, stock combination, reclassification, recapitalization, significant repurchases of stock, or other similar change in the capital structure of the Company shall occur, (c) any extraordinary dividend or other distribution to holders of shares of Common Stock or Units other than regular cash dividends shall be made, or (d) any other event shall occur that in each case in the good faith judgment of the Committee necessitates action by way of appropriate equitable adjustment in the terms of this Award, the LTIP or the 2021 LTIP Units (PB), then the Committee shall take such action as it deems necessary to maintain the Grantee’s rights hereunder so that they are substantially proportionate to the rights existing under this Award, the LTIP and the terms of the 2021 LTIP Units (PB) prior to such event, including, without limitation: (i) adjustments in the 2021 LTIP Units (PB) and the 2021-2 LTIP Units (PB), Share Price, Total Return or other pertinent terms of this Award; and (ii) substitution of other awards under the Stock Plan or otherwise. The Grantee shall have the right to vote the 2021 LTIP Units (PB) if and when voting is allowed under the Partnership Agreement, regardless of whether vesting has occurred.

10.Miscellaneous.

(a)Amendments; Modifications. This Agreement may be amended or modified only with the consent of the Company and the Partnership; provided that any such amendment or modification materially and adversely affecting the rights of the Grantee hereunder must be consented to by the Grantee to be effective as against him; and provided, further, that the Grantee acknowledges that the Stock Plan may be amended or discontinued in accordance with Section 6.6 thereof and that this Agreement may be amended or canceled by the Committee, on behalf of the Company and the Partnership, for the purpose of satisfying changes in law or for any other lawful purpose, so long as no such action shall impair the Grantee’s rights under this Agreement without the Grantee’s written consent. Notwithstanding the foregoing, this Agreement may be amended in writing signed only by the Company to correct any errors or ambiguities in this Agreement and/or to make such changes that do not materially adversely affect the Grantee’s rights hereunder. No promises, assurances, commitments, agreements, undertakings or representations, whether oral, written, electronic or otherwise, and whether express or implied, with respect to the subject matter hereof, have been made by the parties which are not set forth expressly in this Agreement. This grant shall in no way affect the Grantee’s participation or benefits under any other plan or benefit program maintained or provided by the Company.

(b)Incorporation of Stock Plan and Change in Control Arrangement; Committee Determinations. The provisions of the Stock Plan and Change in Control Arrangement are hereby incorporated by reference as if set forth herein. In the event of a conflict between this Agreement and the Stock Plan or this Agreement and the Change in Control Arrangement, this Agreement shall be controlling and determinative. The Committee will make the determinations and certifications required by this Award as promptly as reasonably practicable following the occurrence of the event or events necessitating such determinations or certifications. In the event of a Change of Control, the Committee will perform any calculations set forth in Section 4 or Section 5 hereof required in connection with such Change of Control and make any determinations relevant to vesting with respect to this Award within a period of time that enables the Company to conclude whether 2021 LTIP Units (PB) become vested or are forfeited and whether any 2021-2 LTIP Units (PB) need to be granted not later than prior to the effective date of the Change of Control, which determinations could, for the avoidance of doubt, include good faith assumptions.

(c)Status as a Partner. As of the grant date set forth on Schedule A, the Grantee shall be admitted as a partner of the Partnership with beneficial ownership of the number of 2021 LTIP Units (PB) issued to the Grantee as of such date pursuant to Section 3(a) hereof by: (A) signing and delivering to the Partnership a copy of this Agreement; and (B) signing, as a Limited Partner, and delivering to the Partnership a counterpart signature page to the Partnership Agreement (attached hereto as Exhibit A). The Partnership records shall reflect the issuance to the Grantee of 2021-2 LTIP Units (PB) pursuant to Section 3(b) hereof, if any, whereupon the Grantee shall have the rights of a Limited Partner of the Partnership with respect to the total number of 2021 LTIP Units (PB) then held by the Grantee, as set forth in the Partnership Agreement, subject, however, to the restrictions and conditions specified herein and in the Partnership Agreement.

(d)Status of 2021 LTIP Units (PB) under the Stock Plan. Insofar as the LTIP has been established as an incentive program of the Company and the Partnership, the 2021 LTIP Units (PB) are both issued as equity securities of the Partnership and granted as awards under the Stock Plan. The Company will have the right at its option, as set forth in the Partnership Agreement, to issue shares of Common Stock in exchange for Units into which 2021 LTIP Units (PB) may have been converted pursuant to the Partnership Agreement, subject to certain limitations set forth in the Partnership Agreement, and such shares of Common Stock, if issued, will be issued under the Stock Plan. The Grantee must be eligible to receive the 2021 LTIP Units (PB) in compliance with applicable federal and state securities laws and to that effect is required to complete, execute and deliver certain covenants, representations and warranties (attached as Exhibit B). The Grantee acknowledges that the Grantee will have no right to approve or disapprove such determination by the Committee.

(e)Legend. The records of the Partnership evidencing the 2021 LTIP Units (PB) shall bear an appropriate legend, as determined by the Partnership in its sole discretion, to the effect that such 2021 LTIP Units (PB) are subject to restrictions as set forth herein, in the Stock Plan and in the Partnership Agreement.

(f)Compliance With Securities Laws. The Partnership and the Grantee will make reasonable efforts to comply with all applicable securities laws. In addition, notwithstanding any provision of this Agreement to the contrary, no 2021 LTIP Units (PB) will become vested or be issued at a time that such vesting or issuance would result in a violation of any such laws.

(g)Investment Representations; Registration. The Grantee hereby makes the covenants, representations and warranties set forth on Exhibit B attached hereto. All of such covenants, warranties and representations shall survive the execution and delivery of this Agreement by the Grantee. The Partnership will have no obligation to register under the Securities Act any 2021 LTIP Units (PB) or any other securities issued pursuant to this Agreement or upon conversion or exchange of 2021 LTIP Units (PB). The Grantee agrees that any resale of the shares of Common Stock received upon the exchange of Units into which 2021 LTIP Units (PB) may be converted shall not occur during the “blackout periods” forbidding sales of Company securities, as set forth in the then applicable Company employee manual or insider trading policy. In addition, any resale shall be made in compliance with the registration requirements of the Securities Act or an applicable exemption therefrom, including, without limitation, the exemption provided by Rule 144 promulgated thereunder (or any successor rule).

(h)Section 83(b) Election. In connection with the issuance of 2021 LTIP Units (PB) under this Award pursuant to Section 3 hereof the Grantee may (but is not required to) make an election to include in gross income in the year of transfer the applicable 2021 LTIP Units (PB) pursuant to Section 83(b) of the Code substantially in the form attached hereto as Exhibit C and, if such an election is made, the Grantee shall provide to the Company a copy thereof and supply to the Company such other information as the Company is required to maintain or file in accordance with the regulations promulgated thereunder.

(i)Severability. If, for any reason, any provision of this Agreement is held invalid, such invalidity shall not affect any other provision of this Agreement not so held invalid, and each such other provision shall to the full extent consistent with law continue in full force and effect. If any provision of this Agreement shall be held invalid in part, such invalidity shall in no way affect the rest of such provision not held so invalid, and the rest of such provision, together with all other provisions of this Agreement, shall to the full extent consistent with law continue in full force and effect.

(j)Governing Law. This Agreement is made under, and will be construed in accordance with, the laws of the State of Delaware, without giving effect to the principles of conflict of laws of such state.

(k)No Obligation to Continue Position as an Employee, Consultant or Advisor. Neither the Company nor any affiliate is obligated by or as a result of this Agreement to continue to have the Grantee as an employee, consultant or advisor and this Agreement shall not interfere in any way with the right of the Company or any affiliate to terminate the Grantee’s service relationship at any time.

(l)Notices. Any notice to be given to the Company shall be addressed to the Secretary of the Company at its principal place of business and any notice to be given the Grantee shall be addressed to the Grantee at the Grantee’s address as it appears on the employment records of the Company, or at such other address as the Company or the Grantee may hereafter designate in writing to the other.

(m)Withholding and Taxes. No later than the date as of which an amount first becomes includible in the gross income of the Grantee for income tax purposes or subject to the Federal Insurance Contributions Act withholding with respect to this Award, the Grantee will pay to the Company or, if appropriate, any of its affiliates, or make arrangements satisfactory to the Committee regarding the payment of, any United States federal, state or local or foreign taxes of any kind required by law to be withheld with respect to such amount. The obligations of the Company under this Agreement will be conditional on such payment or arrangements, and the Company and its affiliates shall, to the extent permitted by law, have the right to deduct any such taxes from any payment otherwise due to the Grantee.

(n)Headings. The headings of paragraphs hereof are included solely for convenience of reference and shall not control the meaning or interpretation of any of the provisions of this Agreement.

(o)Counterparts. This Agreement may be executed in multiple counterparts with the same effect as if each of the signing parties had signed the same document. All counterparts shall be construed together and constitute the same instrument.

(p)Successors and Assigns. This Agreement shall be binding upon and inure to the benefit of the parties hereto and any successors to the Company and the Partnership, on the one hand, and any successors to the Grantee, on the other hand, by will or the laws of descent and distribution, but this Agreement shall not otherwise be assignable or otherwise subject to hypothecation by the Grantee.

(q)409A. To the extent applicable, this Agreement shall be construed, administered and interpreted in accordance with a good faith interpretation of Section 409A of the Code. Any provision of this Agreement that is inconsistent with Section 409A of the Code, to the extent applicable, or that may result in penalties under Section 409A of the Code, shall be amended, in consultation with the Grantee and with the reasonable cooperation of the Grantee and the Company, in the least restrictive manner necessary to (i) exclude the applicable payment or benefit under this Agreement from the definition of “deferred compensation” within the meaning of such Section 409A or (ii) comply with the provisions of Section 409A, other applicable provision(s) of the Code and/or any rules, regulations or other regulatory guidance issued under such statutory provisions, in each case without diminution in the value of the benefits granted hereby to the Grantee. Notwithstanding anything herein to the contrary, in the event the amounts payable under this Agreement are determined to constitute “nonqualified deferred compensation” subject to Section 409A of the Code, then, to the extent the Grantee is a “specified employee” under Section 409A of the Code subject to the six-month delay thereunder, any such vesting or related payments to be made during the six-month period commencing on the

Grantee’s “separation from service” (as defined in Section 409A of the Code) shall be delayed until the expiration of such six-month period.

(r)Complete Agreement. This Agreement (together with those agreements and documents expressly referred to herein, for the purposes referred to herein) embody the complete and entire agreement and understanding between the parties with respect to the subject matter hereof, and supersede any and all prior promises, assurances, commitments, agreements, undertakings or representations, whether oral, written, electronic or otherwise, and whether express or implied, which may relate to the subject matter hereof in any way.

IN WITNESS WHEREOF, the undersigned have caused this Award Agreement to be executed as of the 1st day of January, 2021.

The Grantee, desiring to become one of the within named Limited Partners of The Macerich Company, L.P., hereby accepts all of the terms and conditions of (including, without limitation, the provisions related to powers of attorney), and becomes a party to, the Agreement of Limited Partnership, dated as of March 16, 1994, of The Macerich Partnership, L.P., as amended (the “Partnership Agreement”). The Grantee agrees that this signature page may be attached to any counterpart of the Partnership Agreement and further agrees as follows (where the term “Limited Partner” refers to the Grantee):

1.The Limited Partner hereby confirms that it has reviewed the terms of the Partnership Agreement and affirms and agrees that it is bound by each of the terms and conditions of the Partnership Agreement, including, without limitation, the provisions thereof relating to limitations and restrictions on the transfer of Partnership Units. Without limitation of the foregoing, the Limited Partner is deemed to have made all of the acknowledgements, waivers and agreements set forth in Sections 10.6 and 13.11 of the Partnership Agreement.

2.The Limited Partner hereby confirms that it is acquiring the Partnership Units for its own account as principal, for investment and not with a view to resale or distribution, and that the Partnership Units may not be transferred or otherwise disposed of by the Limited Partner otherwise than in a transaction pursuant to a registration statement filed by the Partnership (which it has no obligation to file) or that is exempt from the registration requirements of the Securities Act of 1933, as amended (the “Securities Act”), and all applicable state and foreign securities laws, and the General Partner may refuse to transfer any Partnership Units as to which evidence of such registration or exemption from registration satisfactory to the General Partner is not provided to it, which evidence may include the requirement of a legal opinion regarding the exemption from such registration. If the General Partner delivers to the Limited Partner shares of common stock of the General Partner (“Common Shares”) upon redemption of any Partnership Units, the Common Shares will be acquired for the Limited Partner’s own account as principal, for investment and not with a view to resale or distribution, and the Common Shares may not be transferred or otherwise disposed of by the Limited Partner otherwise than in a transaction pursuant to a registration statement filed by the General Partner with respect to such Common Shares (which it has no obligation under the Partnership Agreement to file) or that is exempt from the registration requirements of the Securities Act and all applicable state and foreign securities laws, and the General Partner may refuse to transfer any Common Shares as to which evidence of such registration or exemption from such registration satisfactory to the General Partner is not provided to it, which evidence may include the requirement of a legal opinion regarding the exemption from such registration.

3.The Limited Partner hereby affirms that it has appointed the General Partner, any Liquidator and authorized officers and attorneys-in-fact of each, and each of those acting singly, in each case with full power of substitution, as its true and lawful agent and attorney-in-fact, with full power and authority in its name, place and stead, in accordance with Section 6.10 of the Partnership Agreement, which Section is hereby incorporated by reference.
