Any resulting fractional unit shall be rounded to the nearest whole unit and shall be rounded up or down as necessary as of the last Vesting Date; provided, in all cases, the Participant cannot vest in more than the number of AO LTIP Units set forth on the Award Certificate.

(f)Conversion and Term. Subject to earlier forfeiture, termination, acceleration, or cancellation of the AO LTIP Units as provided in the Partnership Agreement, Plan, or this Agreement, until the Expiration Date, Vested AO LTIP Units shall be convertible at the Participant’s election into a number of Vested LTIP Units, as determined in accordance with the Partnership Agreement, which in turn may convert into Common Partnership Units (as defined in the Partnership Agreement) and Common Shares as provided in the Partnership Agreement. Vested AO LTIP Units may be converted by the Participant by providing written notice to the Partnership or the Company at least one business day prior to the desired conversion date. Unless otherwise provided in an agreement between the Company and the Participant, upon the Expiration Date any AO LTIP Units that have not been converted into Vested LTIP Units shall terminate, be cancelled for no consideration, and be without further force or effect.

Any Vested AO LTIP Unit not converted during such post-termination conversion window shall be forfeited as of the end of such post-termination conversion window. Any Unvested AO LTIP Units held by the Participant shall be forfeited as of such termination of Service.

(b)Death. Notwithstanding Section 4(a), if the Participant dies while in Service, then any Unvested AO LTIP Units held by the Participant shall immediately become Vested AO LTIP Units as of such Participant’s death. The executors or administrators or legatees or distributees of the Participant’s estate shall have the right, at any time within one year after the date of the Participant’s death (but before the Expiration Date) to convert Vested AO LTIP Units (after taking into account the vesting acceleration pursuant to this Agreement) into Vested LTIP Units pursuant to the terms of this Agreement and the Partnership Agreement. Any Vested AO LTIP Unit not converted during such post-termination conversion window shall immediately be forfeited as of the end of such post-termination conversion window.

(c)Disability. Notwithstanding Section 4(a), if the Participant’s Service terminates by reason of the Participant’s Disability, then any Unvested AO LTIP Units shall immediately become Vested AO LTIP Units as of such Participant’s termination.

Any Vested AO LTIP Unit not converted during such post-termination conversion window shall immediately be forfeited as of the end of such post-termination conversion window.

Notwithstanding Section 4(a), if the Participant’s Service terminates by reason of the Participant’s retirement from the Board pursuant to any mandatory retirement policy or at a time when the Participant (i) is at least age 55, (ii) has provided Services (as defined under the Plan) for a minimum of 10 years to the Company, PS Business Parks, Inc. (prior to July 20, 2022), and their Affiliates, and (iii) the sum of the Participant’s age and years of Service is at least 80 (“Retirement”), then upon such Retirement, all Unvested AO LTIP Units, if any, that have not previously vested shall immediately become Vested AO LTIP Units. The Participant shall have the right, at any time within one year after the date of such termination (but before the Expiration Date) to convert Vested AO LTIP Units (after taking into account the vesting

acceleration pursuant to this Agreement) into Vested LTIP Units pursuant to the terms of this Agreement and the Partnership Agreement.

If the Committee determines at any time that an Unvested AO LTIP Unit cannot become a Vested AO LTIP Unit, the Committee shall have the authority to cause such Unvested AO LTIP Unit to be forfeited for no consideration and without liability to the Participant under the Award.

(b)Agreement Subject to Plan and Partnership Agreement; Amendment. By entering into this Agreement, the Participant agrees and acknowledges that the Participant has received and read a copy of the Plan and the Partnership Agreement. The AO LTIP Units granted hereunder are subject to the Plan and the Partnership Agreement. The terms

and provisions of the Plan and the Partnership Agreement, as the same may be amended from time to time, are hereby incorporated herein by reference. In the event of a conflict between any term or provision contained herein and a term or provision of the Plan or the Partnership Agreement, the applicable terms and provisions of the Plan or the Partnership Agreement as applicable, will govern and prevail. The terms of the Agreement and the Award Certificate may be amended from time to time by the Committee in its sole discretion in any manner that it deems appropriate; provided, that any such amendment that would materially and adversely affect any right of the Participant shall not to that extent be effective without the consent of the Participant.

(c)No Transferability; No Assignment. Except as set forth in the Partnership Agreement, the Participant shall not, without the consent of the Partnership (which the Partnership may give or withhold in its sole discretion), sell, pledge, assign, hypothecate, transfer, or otherwise dispose of (collectively, “Transfer”) any AO LTIP Units.

(d)No Right to Continued Employment. Neither the Plan nor this Agreement nor the Participant’s receipt of the Award hereunder shall impose any obligation on the Company or any Affiliate to continue the Service of the Participant. Further, the Company or any Affiliate (as applicable) may at any time terminate the Service of such Participant, free from any liability or claim under the Plan or this Agreement, except as otherwise expressly provided herein or in any written employment agreement between the Participant and the Company (or any Affiliate).

(e)Limitation on Rights. The Participant shall be the record owner of the AO LTIP Units, and as record owner shall be entitled to all rights of a holder of AO LTIP Units under the Partnership Agreement.

(f)Legend. To the extent applicable, all book entries (or certificates, if any) representing the AO LTIP Units delivered to the Participant as contemplated by Section 2 above shall be subject to applicable law. Any such book entry notations (or legends on certificates, if any) shall include a description to the effect of the restrictions set forth in Section 5(c) hereof.

(g)Securities Laws; Cooperation. The Participant will make or enter into such written representations, warranties, and agreements as the Committee may reasonably request in order to comply with applicable securities laws or with this Agreement. Participant further agrees to cooperate with the Company and the Partnership in taking any action reasonably necessary or advisable to consummate the transactions contemplated by this Agreement.

(h)Tax Withholding.

(i)Regardless of any action that the Company, the Partnership, the General Partner, the Partnership, or any of their Affiliates (collectively, the “Company Parties”) takes or fails to take with respect to any or all federal, state, or local income tax, employment tax, non-U.S. tax, or other tax-related items (“Tax Related Items”), the Participant acknowledges that the ultimate liability for

all Tax Related Items associated with the Vested AO LTIP Units (and any distributions in respect thereof) is and remains the Participant’s responsibility and that each of the Company Parties: (A) makes no representations or undertakings regarding the treatment of any Tax Related Items in connection with any aspect of the Vested AO LTIP Units, including, but not limited to, the grant, vesting, or conversion, any exchange pursuant to Section 8.6 of the Partnership Agreement, the subsequent sale of Common Shares and the receipt of any distributions in respect thereof; and (B) does not commit to structure the terms of the Award or any aspect of the Vested AO LTIP Units to reduce or eliminate the Participant’s liability for Tax Related Items. Further, if Participant has relocated to a different jurisdiction between the date of grant and the date of any taxable event, the Participant acknowledges that the Partnership and/or Company may be required to withhold or account for Tax Related Items in more than one jurisdiction.

(ii)If applicable, prior to the relevant taxable event, the Participant shall pay or make adequate arrangements satisfactory to the Partnership and/or the Company, in its sole discretion, to satisfy all withholding and payment on account obligations for Tax Related Items of the Company and the Partnership. In this regard, the Participant authorizes the Company and the Partnership, each in its sole discretion, to satisfy the obligations with regard to all Tax Related Items legally payable by the Participant with respect to the AO LTIP Units by withholding cash or securities otherwise payable or issuable to the Participant, provided that the Company and/or the Partnership withholds only the amount necessary to satisfy the minimum statutory withholding amount using, in the case of securities, the Fair Market Value of the securities. Notwithstanding the foregoing, for so long as Accounting Standards Update 2016-09 or a similar rule remains in effect, the Board or the Committee shall have full discretion to choose, or to allow a Participant to elect, to withhold amounts having an aggregate Fair Market Value that is greater than the applicable minimum required statutory withholding liability (but such withholding may in no event be in excess of the maximum required statutory withholding amount(s) in such Participant’s relevant tax jurisdictions). Participant shall pay to the Company and/or the Partnership any amount of Tax Related Items that the Company and/or the Partnership may be required to withhold that are not satisfied by the previously described method. The Company may refuse to deliver cash or securities to the Participant if the Participant fails to comply with Participant’s obligations in connection with the Tax Related Items as described in this Section.

(i)Compensation Recovery Policy. The property received under this Agreement shall be subject to being recovered under the Company’s Incentive Compensation Recoupment Policy, and any similar policy that the Company may adopt from time to time. For avoidance of doubt, compensation recovery rights to Vested AO LTIP Units under this Agreement shall extend to Vested LTIP Units that were received upon conversion of Vested AO LTIP Units, Common Partnership Units received upon the conversion of such LTIP Units, and any cash or Common Shares received upon redemption of such Common Partnership Units.

(j)Section 409A Compliance. The Award and the AO LTIP Units under this Agreement are intended either to be exempt from, or to comply with, the requirements of Section 409A of the Code, so as to prevent the inclusion in gross income of any benefits accrued hereunder in a taxable year prior to the taxable year or years in which such amount would otherwise be actually distributed or made available to the Participants. The Agreement shall be administered and interpreted to the extent possible in a manner consistent with that intent. Notwithstanding anything to the contrary in this Agreement, if the Participant is a “specified employee” within the meaning of Section 409A, no payments in respect of any Award or AO LTIP Unit that is “deferred compensation” subject to Section 409A and that would otherwise be payable upon the Participant’s “separation from service” (as defined in Section 409A) shall be made to the Participant prior to the date that is six months after the date of the Participant’s “separation from service” or, if earlier, the Participant’s date of death. Following any applicable six-month delay, all such delayed payments will be paid in a single lump sum on the earliest date permitted under Section 409A that is also a business day. The Participant is solely responsible and liable for the satisfaction of all taxes and penalties under Section 409A that may be imposed on or in respect of the Participant in connection with this Agreement, and the Company and the Partnership shall not be liable to the Participant or any other person for any payment made under this plan that is determined to result in an additional tax, penalty, or interest under Section 409A, nor for reporting in good faith any payment made under this Agreement as an amount includible in gross income under Section 409A.

(k)Section 280G of the Code. If the accelerated vesting of the AO LTIP Units or the amounts payable under this Agreement, together with all other payments and the value of any benefit received or to be received by the Participant, would result in all or a portion of such payment being subject to excise tax under Section 4999 of the Code (the “Excise Tax”), then the Participant’s payment shall be either (i) the full payment or (ii) such lesser amount that would result in no portion of the payment being subject to the Excise Tax, whichever of the foregoing amounts, taking into account the applicable federal, state, and local employment taxes, income taxes, and the Excise Tax, results in the receipt by the Participant, on an after-tax basis, of the greatest amount of the payment notwithstanding that all or some portion of the payment may be taxable under Section 4999 of the Code. Any such reduction shall be made by the Company and/or the Partnership in compliance with all applicable legal authority, including Section 409A. All determinations required to be made under this Section shall be made by the nationally recognized accounting firm that is the Company’s outside auditor immediately prior to the event triggering the payments that are subject to the Excise Tax, which firm must be reasonably acceptable to the Participant (the “Accounting Firm”). The Company shall cause the Accounting Firm to provide detailed supporting calculations of its determinations to the Company, the Partnership, and the Participant. All fees and expenses of the Accounting Firm shall be borne solely by the Company. The Accounting Firm’s determinations must be made with substantial authority (within the meaning of Section 6662 of the Code).

(l)Governing Law. This Agreement shall be governed by the laws of the State of Maryland, except that if Participant’s principal place of employment is in California, then this Agreement will be governed by the laws of the State of California, in either case without giving effect to any choice or conflict of law provision or rule.

(m)Signature in Counterparts. This Agreement may be signed in counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument.

1.Public Storage OP, L.P. (the “Partnership”), Public Storage, a Maryland real estate investment trust (together with its Subsidiaries and their successors, the “Company”), and the Participant who is signatory hereto, hereby agree to the terms of this Award Certificate and the Public Storage OP, L.P. AO LTIP Unit Agreement (the “Agreement”) to which it is attached.

3.The Award and any AO LTIP Units which may vest under the Award are subject to the terms and conditions set forth in this Award Certificate, the Plan, the Agreement and the Partnership’s partnership agreement (the “Partnership Agreement”).

If any provision of this Award Certificate is in conflict with the terms of the Plan, the Agreement, or the Partnership Agreement, then the terms of the Plan, the Agreement, or the Partnership Agreement, as applicable, shall govern.
