1. Issuance of LTIP Units. The Participant shall be issued, by the Partnership, a total of [INSERT NUMBER] LTIP Units, subject to the terms and conditions set forth herein, in the Plan and in the Third Amended and Restated Limited Partnership Agreement of SmartStop OP, L.P., effective as of June 28, 2019, as amended by Amendment No. 1, effective as of October 29, 2019, Amendment No. 2, effective as of January 1, 2020, Amendment No. 3 effective as of March 24, 2021, and Amendment No. 4 effective as of January 1, 2020, and as may be subsequently amended or amended and restated (the “Partnership Agreement”). Upon receipt of the Award, the Participant shall, automatically and without further action on his or her part, be deemed to be a party to, signatory of and bound by the Partnership Agreement. At the request of the Partnership, the Participant shall execute the Partnership Agreement or a joinder or counterpart signature page thereto.

The Award shall have the rights, voting powers, restrictions, limitations as to distributions, qualifications and terms and conditions of redemption and conversion set forth herein, in the Plan and in the Partnership Agreement.

In the Participant’s discretion and subject to the consent of the General Partner, the Participant may direct that the Company issue the LTIP Units to a revocable living trust established for the exclusive benefit of the Participant or the Participant and his or her spouse, provided that the Participant shall remain responsible for the satisfaction of all duties and obligations under the Award and under the Plan, including tax obligations.

2. Definitions. For purposes of this Agreement, the following terms shall have the meanings set forth below. All capitalized terms used but not otherwise defined herein shall have the meanings ascribed to such terms in the Plan and/or the Partnership Agreement, as applicable.

3. LTIP Units Subject to Partnership Agreement; Transfer Restrictions.

(a) LTIP Units are subject to the terms of the Plan, this Agreement and the Partnership Agreement, including, without limitation, the restrictions on transfer of Units (including, without limitation, LTIP Units) set forth therein.

(b) Except as otherwise provided in Section 3(c) below, without the consent of the General Partner (which it may give or withhold in its sole discretion), the Participant shall not sell, pledge, assign, hypothecate, transfer, or otherwise dispose of (collectively, “Transfer”) any unvested LTIP Units or any portion of the Award attributable to such unvested LTIP Units (or any securities into which such unvested LTIP Units are converted or exchanged), other than by will or pursuant to the laws of descent and distribution (the “Transfer Restrictions”); provided, however, that (i) the Participant may direct that the Company issue the LTIP Units to a revocable living trust as described in Section 1 above and (ii) the Transfer Restrictions shall not apply to any Transfer of unvested LTIP Units or Award to the Partnership or the Company.

(c) Any permitted transferee of the Award or LTIP Units shall take such Award or LTIP Units subject to the terms of the Plan, this Agreement, and the Partnership Agreement. Any such permitted transferee must, upon the request of the Partnership, execute a joinder or counterpart signature page to the Partnership Agreement, and must agree to such other waivers, limitations, and restrictions as the Partnership or the Company may reasonably require. Any Transfer of the Award or LTIP Units which is not made in compliance with the Plan, the Partnership Agreement and this Agreement shall be null and void and of no effect ab initio. Notwithstanding any other provision of this Agreement, without the consent of the General Partner (which it may give or withhold in its sole discretion), other than by will or the laws of descent and distribution, the Participant shall not Transfer the LTIP Units, including by means of a redemption of such LTIP Units by the Partnership, until the earlier of (i) the occurrence of, and in connection with, a Change of Control (or such earlier time as is necessary in order for the Participant to participate in such Change of Control transaction with respect to the LTIP Units and receive the consideration payable with respect thereto in connection with such Change of Control) or (ii) the date such LTIP Units become vested.

(d) At least two weeks prior (the “Notice Period”) to any proposed Transfer of vested or unvested LTIP Units, the Participant shall provide the Company with written notice of such proposed Transfer. Such notice of a proposed Transfer may be withdrawn at any time prior to expiration of the Notice Period.

4. Vesting.

(a) Time Vesting. Subject to Sections 4(b) and 5 hereof, the Restrictions shall lapse and the LTIP Units shall vest and become nonforfeitable with respect to 25% of the LTIP Units on each of the first four anniversaries of the Grant Date, subject to the Participant’s continued employment or service with the Company, the Partnership, SmartStop Advisors or any other Affiliate through the applicable vesting date.

(b) Change of Control. In the event of a Change of Control, (i) with respect to a Participant that is subject to the Severance Plan, the vesting of the LTIP Units shall be governed by the Severance Plan, as in effect at the time of such Change of Control, or, if no such Severance Plan is in place, the Severance Plan last in effect prior to such Change of Control; and (ii) with respect to a Participant that is not subject to the Severance Plan, the LTIP Units shall vest and become nonforfeitable upon such Change of Control.

7. Execution and Return of Documents and Certificates. At the Company’s or the Partnership’s request, the Participant hereby agrees to promptly execute, deliver and return to the Partnership any and all documents or certificates that the Company or the Partnership deems necessary or desirable to effectuate the cancellation and forfeiture of the unvested LTIP Units (pursuant to the Restrictions) and the portion of the Award attributable thereto, and/or to effectuate the transfer or surrender of such unvested LTIP Units to the Partnership.

8. Covenants, Representations and Warranties. As a condition to the receipt of this Award, the Participant agrees to execute any investor representation or covenant determined by the Company or the Partnership to satisfy an exception under, or to otherwise comply with, the Securities Act of 1933, as amended (the “Securities Act”), including the representations attached hereto as Exhibit C. Furthermore, the Participant hereby represents, warrants, covenants, acknowledges and agrees on behalf of the Participant and his or her spouse, if applicable, that:

(a) Investment. The Participant is holding the Award and the LTIP Units for the Participant ’s own account, and not for the account of any other person. The Participant is holding the Award and the LTIP Units for investment and not with a view to distribution or resale thereof except in compliance with applicable laws regulating securities.

(b) Relation to the Company and the Partnership. The Participant is presently an employee of the Company, the Partnership, SmartStop Advisors, or any other Affiliate and is providing services to or for the benefit of the Partnership, and in such capacity has become personally familiar with the business of the Partnership.

(c) Access to Information. The Participant has had the opportunity to ask questions of, and to receive answers from, the Company and the Partnership with respect to the terms and conditions of the transactions contemplated hereby and with respect to the business, affairs, financial conditions, and results of operations of the Partnership.

(d) Registration. The Participant understands that the LTIP Units have not been registered under the Securities Act, and the LTIP Units cannot be transferred by the Participant unless such transfer is registered under the Securities Act or an exemption from such registration is available. The Partnership has made no agreements, covenants or undertakings whatsoever to register the transfer of the LTIP Units under the Securities Act. The Partnership has made no representations, warranties, or covenants whatsoever as to whether any exemption from the Securities Act, including, without limitation, any exemption for limited sales in routine brokers’ transactions pursuant to Rule 144 of the Securities Act, shall be available. If an exemption under Rule 144 is available at all, it shall not be available until at least six months from issuance of the Award and then not unless the terms and conditions of Rule 144 have been satisfied.

(e) Public Trading. None of the Partnership’s securities are presently publicly traded, and the Partnership has made no representations, covenants or agreements as to whether there will be a public market for any of its securities.

(f) Tax Advice. The Partnership and the Participant intend that (i) the LTIP Units be treated as a “profits interest” as defined in Internal Revenue Service Revenue Procedure 93-27 (“Rev. Proc. 93-27”), as clarified by Revenue Procedure 2001-43 (“Rev. Proc. 2001-43”), (ii) the issuance of such units not be a taxable event to the Partnership or the Participant as provided in such revenue procedure, and (iii) the Partnership Agreement, the Plan and this Agreement be interpreted consistently with such intent. In furtherance of such intent, effective immediately prior to the issuance of the LTIP Units, the Partnership may revalue all Partnership assets to their respective gross fair market values, and make the resulting adjustments to the “Capital Accounts” (as defined in the Partnership Agreement) of the partners, in each case as set forth in the Partnership Agreement. The Company, the Partnership, SmartStop Advisors, or any other Affiliate may withhold from the Participant’s wages, or require the Participant to pay to such entity, any applicable withholding or employment taxes resulting from the issuance of the Award hereunder, from the vesting or lapse of any restrictions imposed on the Award, or from the ownership or disposition of the LTIP Units, provided, however, that neither the Company nor the Partnership has made warranties or representations to the Participant with respect to the income tax consequences of the transactions contemplated by this Agreement (including, without limitation, with respect to the decision of whether to make an election under Section 83(b) of the Code), and the Participant is in no manner relying on the Company or the Partnership or its representatives for an assessment of such tax consequences. Participant hereby recognizes that the Internal Revenue Service has proposed regulations under Sections 83 and 704 of the Code that may affect the proper treatment of the LTIP Units for federal income tax purposes. In the event that those proposed regulations are finalized, the Participant hereby agrees to cooperate with the Partnership in amending this Agreement and the Partnership Agreement, and to take such other action as may be required, to conform to such regulations. The Participant is advised to consult with his or her own tax advisor with respect to such tax consequences and his or her ownership of the LTIP Units.

(g) Notice Regarding Transfers. In further acknowledgement of the intended tax treatment discussed in Section 8(f) above, and notwithstanding the restrictions on transfers of the LTIP Units imposed under the terms of this Agreement, the Participant acknowledges that a Transfer of the LTIP Units within the three-year period following the date of this Agreement may result in adverse tax consequences to the Participant. Such adverse tax consequences may include, without limitation: (i) the LTIP Units failing to be treated as a “profits interest” as defined in Rev. Proc. 93-27 and Rev. Proc. 2001-43 and (ii) gains associated with any disposition of the LTIP Units, not being taxed at the long-term capital gains rate.

9. Capital Account. The Participant shall make no contribution of capital to the Partnership in connection with the Award and, as a result, the Participant’s Capital Account balance in the Partnership immediately after its receipt of the LTIP Units shall be equal to zero, unless the Participant was a Partner in the Partnership prior to such issuance, in which case the Participant’s Capital Account balance shall not be increased as a result of its receipt of the LTIP Units.

10. Section 83(b) Election. The Participant covenants that the Participant shall make a timely election under Section 83(b) of the Code (and any comparable election in the state of the Participant’s residence) with respect to the LTIP Units covered by the Award, and the Partnership hereby consents to the making of such election(s). In connection with such election, the Participant and the Participant’s spouse, if applicable, shall promptly provide a copy of such election to the Partnership. Instructions for completing an election under Section 83(b) of the Code and a form of election under Section 83(b) of the Code are attached hereto as Exhibit A. The Participant represents that the Participant has consulted any tax advisor(s) that the Participant deems advisable in connection with the filing of an election under Section 83(b) of the Code and similar state tax provisions. The Participant acknowledges that it is the Participant’s sole responsibility, and not the Company’s or the Partnership’s, to timely file an election under Section 83(b) of the Code (and any comparable state election), even if the Participant requests that the Company or the Partnership, or any representative of the Company or the Partnership, make such filing on the Participant’s behalf. The Participant should consult his or her tax advisor to determine if there is a comparable election to file in the state of his or her residence.

11. Ownership Information. The Participant hereby covenants that so long as the Participant holds any LTIP Units, at the request of the Partnership, the Participant shall disclose to the Partnership in writing such information relating to the Participant’s ownership of the LTIP Units as the Partnership reasonably believes to be necessary or desirable to ascertain in order to comply with the Code or the requirements of any other appropriate taxing authority.

12. Remedies. The Participant shall be liable to the Partnership for all costs and damages, including incidental and consequential damages, resulting from a disposition of the Award or the LTIP Units which is in violation of the provisions of this Agreement. Without limiting the generality of the foregoing, the Participant agrees that the Partnership shall be entitled to obtain specific performance of the obligations of the Participant under this Agreement and immediate injunctive relief in the event any action or proceeding is brought in equity to enforce the same. The Participant shall not urge as a defense that there is an adequate remedy at law.

13. Restrictive Legends. Certificates evidencing the Award, to the extent such certificates are issued, may bear such restrictive legends as the Partnership and/or the Partnership’s counsel may deem necessary or advisable under applicable law or pursuant to this Agreement, including, without limitation, the following legends or any legends similar thereto:

“The securities represented hereby have not been registered under the Securities Act of 1933, as amended (the “Securities Act”). Any transfer of such securities shall be invalid unless a Registration Statement under the Securities Act is in effect as to such transfer or in the opinion of counsel for SmartStop OP, L.P. (the “Partnership”) such registration is unnecessary in order for such transfer to comply with the Securities Act.”

“The securities represented hereby are subject to forfeiture, transferability and other restrictions as set forth in (i) the SmartStop Self Storage REIT, Inc. and SmartStop OP, L.P. Time-Based LTIP Unit Agreement, (ii) the SmartStop Self Storage REIT, Inc. 2022 Long-Term Incentive Plan, and (iii) the Third Amended and Restated Limited Partnership Agreement of SmartStop OP, L.P., in each case, as has been and as may in the future be amended (or amended and restated) from time to time, and such securities may not be sold or otherwise transferred except pursuant to the provisions of such documents.”

14. Restrictions on Public Sale by the Participant. To the extent not inconsistent with applicable law, the Participant agrees not to effect any sale or distribution of the LTIP Units or any similar security of the Company or the Partnership, or any securities convertible into or exchangeable or exercisable for such securities, including a sale pursuant to Rule 144 under the Securities Act, during the 14 days prior to, and for a period of up to 90 days beginning on the date of the pricing of any public or private debt or equity securities offering by the Company or the Partnership (except as part of such offering), if and to the extent requested in writing by the Partnership or the Company in the case of a non-underwritten public or private offering or if and to the extent requested in writing by the managing underwriter or underwriters (or initial purchaser or initial purchasers, as the case may be) and consented to by the Partnership or the Company, which consent may be given or withheld in the Partnership’s or the Company’s sole and absolute discretion, in the case of an underwritten public or private offering (such agreement to be in the form of a lock-up agreement provided by the Company, the Partnership, managing underwriter or underwriters, or initial purchaser or initial purchasers, as the case may be).

15. Code Section 409A. To the extent applicable, this Agreement shall be interpreted so that this Award is exempt from (or, to the extent that exemption is not possible, to comply with) Section 409A of the Code and Department of Treasury regulations and other interpretive guidance issued thereunder, including without limitation any such regulations or other guidance that may be issued after the effective date of this Agreement. Notwithstanding any provision of this Agreement to the contrary, in the event that following the effective date of this Agreement, the Company or the Partnership determines that the Award must be revised to maintain exemption from or to comply with Section 409A of the Code and related Department of Treasury guidance (including such Department of Treasury guidance as may be issued after the effective date of this Agreement), the Company or the Partnership may adopt such amendments to this Agreement or adopt other policies and procedures (including amendments, policies and procedures with retroactive effect), or take any other actions, that the Company or the Partnership determines are necessary or appropriate to (a) exempt the Award from Section 409A of the Code and/or preserve the intended tax treatment of the benefits provided with respect to the Award, or (b) comply with the requirements of Section 409A of the Code and related Department of Treasury guidance; provided, however, that this Section 15 shall not create any obligation on the part of the Company, the Partnership or any Subsidiary to adopt any such amendment, policy or procedure or take any such other action, and none of the Company, the Partnership or any Subsidiary shall have any obligation to indemnify any person for any taxes imposed under or by operation of Section 409A of the Code.
