1 US-DOCS\140855887.2 EXHIBIT A RESTRICTED STOCK UNIT AGREEMENT Capitalized terms not specifically defined in this Restricted Stock Unit Agreement (this “Agreement”) have the meanings specified in the Grant Notice or, if not defined in the Grant Notice, in the Plan. ARTICLE I. GENERAL 1.1 Award of RSUs. The Company has granted the RSUs to Participant effective as of the Grant Date set forth in the Grant Notice (the “Grant Date”). Each RSU represents the right to receive one Share as set forth in this Agreement. Participant will have no right to the distribution of any Shares until the time (if ever) the RSUs have vested. 1.2 Incorporation of Terms of Plan. The RSUs are subject to the terms and conditions set forth in this Agreement and the Plan, which is incorporated herein by reference. In the event of any inconsistency between the Plan and this Agreement, the terms of the Plan will control. 1.3 Unsecured Promise. The RSUs will at all times prior to settlement represent an unsecured Company obligation payable only from the Company’s general assets. 1.4 Participant’s Representations. If the Shares acquired upon the distribution of the RSUs have not been registered under the Securities Act or any applicable state laws at the time the RSUs are settled, Participant shall, if required by the Company, deliver to the Company his or her Investment Representation Statement (in the form attached hereto as Exhibit B) and shall make such other written representations as are deemed necessary or appropriate by the Company and/or its counsel. 1.5 Lock-Up Period. Participant hereby agrees that if so requested by the Company or any representative of a lead underwriter of the Company’s securities (the “Managing Underwriter”) in connection with (a) any registration of the offering of any securities of the Company under the Securities Act or any applicable state laws, and/or (b) any offering of securities exempt from registration under Rule 144A of the Securities Act by the Company, Participant shall not sell or otherwise transfer any Shares or other securities of the Company during the 180-day period (or such longer period as may be requested by the Managing Underwriter or the Company) following (i) the effective date of a registration statement filed by the Company under the Securities Act, or (ii) the date of consummation of such offering pursuant to Rule 144A. The Company may impose stop transfer instructions with respect to securities subject to the foregoing restrictions until the end of such 180-day period. 1.6 Restrictions on Shares. Participant hereby agrees that Shares acquired upon the distribution of the RSUs shall be subject to such terms and conditions as the Administrator shall determine in its sole discretion, including, without limitation, restrictions on the transferability of Shares, the right of the Company to repurchase Shares, the right of the Company to require that Shares be transferred in the event of certain transactions, a right of first refusal in favor of the Company with respect to permitted transfers of Shares, tag-along rights and bring-along rights, including such terms and conditions as set forth in Sections 4.1, 4.2 and 4.3 herein. Notwithstanding the foregoing, such terms and conditions may, in the Administrator’s sole discretion, be contained in such other agreement as the Administrator shall determine and which Participant hereby agrees to enter into at the request of the Company.

2 US-DOCS\140855887.2 ARTICLE II. VESTING; FORFEITURE AND SETTLEMENT 2.1 Vesting; Forfeiture. The RSUs will vest according to the vesting schedule in the Grant Notice except that any fraction of an RSU that would otherwise be vested will be accumulated and will vest only when a whole RSU has accumulated. In the event that Participant experiences a Termination of Service due to the Company, or any successor entity thereto, removing Participant from the Board or causing Participant not to be re-nominated to the Board, then the RSUs will accelerate and become fully vested as of the date of termination. In the event of Participant’s Termination of Service for any other reason, all unvested RSUs will immediately and automatically be cancelled and forfeited, except as otherwise determined by the Administrator or provided in a binding written agreement between Participant and the Company. 2.2 Settlement. Subject to Section 4.16 hereof, the Shares subject to the RSUs, to the extent vested, will be delivered on the 12-month anniversary following the date of Participant’s “separation from service” from the Company within the meaning of Section 409A(a)(2)(A)(i) of the Code (a “Separation from Service”) with respect to the Company (the “Distribution Event”). Notwithstanding anything to the contrary contained herein, the exact payment date of any RSUs shall be determined by the Company in its sole discretion (and Participant shall not have a right to designate the time of payment). ARTICLE III. TAXATION AND TAX WITHHOLDING 3.1 Representation. Participant represents to the Company that Participant has reviewed with Participant’s own tax advisors the tax consequences of this award of RSUs (the “Award”) and the transactions contemplated by the Grant Notice and this Agreement. Participant is relying solely on such advisors and not on any statements or representations of the Company or any of its agents. 3.2 Tax Withholding. Participant acknowledges that Participant is ultimately liable and responsible for all taxes owed in connection with the RSUs, including to the extent that any Federal Insurance Contributions Act (“FICA”) tax withholding obligations arise in connection with Participant’s RSUs prior to settlement, regardless of any action the Company or any Subsidiary takes with respect to any tax withholding obligations that arise in connection with the RSUs. Neither the Company nor any Subsidiary makes any representation or undertaking regarding the treatment of any tax withholding in connection with the awarding, vesting or payment of the RSUs or the subsequent sale of Shares. The Company and its Subsidiaries do not commit and are under no obligation to structure the RSUs to reduce or eliminate Participant’s tax liability. To the extent that any FICA tax withholding obligations arise in connection with the RSUs, the Company shall accelerate the payment of a number of RSUs sufficient to satisfy (but not in excess of) such tax withholding obligations and any tax withholding obligations associated with such accelerated payment, and the Company shall withhold such amounts in satisfaction of such withholding obligations. ARTICLE IV. OTHER PROVISIONS 4.1 Participant’s Rights to Transfer Shares. (a) Company’s Right of First Refusal. Before any Shares received with respect to the RSUs held by Participant or any permitted transferee (each, a “Holder”) may be sold, pledged, assigned, hypothecated, transferred, or otherwise disposed of (including transfer by gift or operation of law and,

3 US-DOCS\140855887.2 collectively, “Transfer” or “Transferred”), the Company or its assignee(s) shall have a right of first refusal to purchase the Shares on the terms and conditions set forth in this Section (the “Right of First Refusal”). (i) Notice of Proposed Transfer. The Holder of the Shares shall deliver to the Company a written notice (the “Notice”) stating: (A) the Holder’s bona fide intention to sell or otherwise Transfer such Shares; (B) the name of each proposed purchaser or other transferee (“Proposed Transferee”); (C) the number of Shares to be Transferred to each Proposed Transferee; and (D) the bona fide cash price or other consideration for which the Holder proposes to Transfer the Shares (the “Offered Price”), and the Holder shall offer the Shares at the Offered Price to the Company or its assignee(s). (ii) Exercise of Right of First Refusal. Within thirty (30) days after receipt of the Notice, the Company and/or its assignee(s) may elect in writing to purchase all, but not less than all, of the Shares proposed to be Transferred to any one or more of the Proposed Transferees. The purchase price will be determined in accordance with paragraph (iii) below. (iii) Purchase Price. The purchase price (the “Purchase Price”) for the Shares repurchased under this Section shall be the Offered Price. If the Offered Price includes consideration other than cash, the cash equivalent value of the non-cash consideration shall be determined by the Board or the Administrator in good faith. (iv) Payment. Payment of the Purchase Price shall be made, at the option of the Company or its assignee(s), in cash (by check), by cancellation of all or a portion of any outstanding indebtedness of the Holder to the Company (or, in the case of repurchase by an assignee, to the assignee), or by any combination thereof within thirty (30) days after receipt of the Notice or in the manner and at the times set forth in the Notice. (v) Holder’s Right to Transfer. If all of the Shares proposed in the Notice to be transferred to a given Proposed Transferee are not purchased by the Company and/or its assignee(s) as provided in this Section, then the Holder may sell or otherwise Transfer such Shares to that Proposed Transferee at the Offered Price or at a higher price, provided that such sale or other Transfer is consummated within one hundred twenty (120) days after the date of the Notice and provided further that any such sale or other Transfer is effected in accordance with any applicable securities laws and the Proposed Transferee agrees in writing that the provisions of this Section shall continue to apply to the Shares in the hands of such Proposed Transferee. If the Shares described in the Notice are not Transferred to the Proposed Transferee within such period, a new Notice shall be given to the Company, and the Company and/or its assignees shall again be offered the Right of First Refusal as provided herein before any Shares held by the Holder may be sold or otherwise Transferred. (b) Exception for Certain Family Transfers. Anything to the contrary contained in this Section notwithstanding, the Transfer of any or all of the Shares during Participant’s lifetime or on Participant’s death by will or intestacy to Participant’s Immediate Family (as defined below) or a trust for the benefit of Participant’s Immediate Family shall be exempt from the Right of First Refusal. As used herein, “Immediate Family” shall mean spouse, lineal descendant or antecedent, father, mother, brother or sister or stepchild (whether or not adopted). In such case, the transferee or other recipient shall receive and hold the Shares so Transferred subject to the provisions of this Section (including the Right of First Refusal) and there shall be no further Transfer of such Shares except in accordance with the terms of this Section. (c) Termination of Right of First Refusal. The Right of First Refusal shall terminate as to all Shares upon the date of the initial sale of Common Stock of the Company to the general public

4 US-DOCS\140855887.2 pursuant to a registration statement filed with and declared effective by the Securities and Exchange Commission under the Securities Act (an “Initial Public Offering”). For the avoidance of doubt, an Initial Public Offering shall include any direct listing of the Company’s equity or any going public transaction (or series of transactions) effected through a special purpose acquisition company that results in the Company or its successor in interest having equity securities listed for trading on a national securities exchange, whether or not the Company is deemed to issue equity securities in connection therewith. 4.2 Company Call Right (a) If Participant ceases to be a Service Provider for any reason, the Company shall have the right to purchase from Participant, or Participant’s personal representative, as the case may be, any or all of the Shares then owned by Participant at a per Share price equal to the Fair Market Value of a Share on the date on which Participant ceases to be a Service Provider (the “Call Right”). (b) The Company may exercise the Call Right by delivering personally or by registered mail to Participant (or his transferee or legal representative, as the case may be), within ninety (90) days after the date on which Participant ceases to be a Service Provider (or, in the case of Shares which are acquired after the date on which Participant ceases to be a Service Provider, then within ninety (90) days after the date on which such Shares are acquired), a notice in writing indicating the Company’s intention to exercise the Call Right and setting forth a date for closing not later than thirty (30) days from the mailing of such notice. The closing shall take place at the Company’s office. At the closing, the holder of the certificates for the Shares being transferred shall deliver the stock certificate or certificates evidencing the Shares, and the Company shall deliver the purchase price therefor. (c) At its option, the Company may elect to make payment for the Shares to a bank selected by the Company. The Company shall avail itself of this option by a notice in writing to Participant stating the name and address of the bank, date of closing, and waiving the closing at the Company’s office. (d) If the Company does not elect to exercise the Call Right conferred above by giving the requisite notice within the time provided in Subsection (b) above, the Call Right shall terminate. (e) The Call Right shall terminate as to all Shares upon the date of an Initial Public Offering. 4.3 Restrictive Legends and Stop-Transfer Orders. (a) Legends. Participant understands and agrees that the Company shall cause the legends set forth below or legends substantially similar thereto, to be placed upon any certificate(s) evidencing ownership of the Shares together with any other legends that may be required by state or federal securities laws: THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933 (THE “ACT”) OR ANY APPLICABLE STATE SECURITIES LAWS AND MAY NOT BE OFFERED, SOLD OR OTHERWISE TRANSFERRED, PLEDGED OR HYPOTHECATED UNLESS AND UNTIL REGISTERED UNDER THE ACT AND SUCH LAWS OR, IN THE OPINION OF COUNSEL IN FORM AND SUBSTANCE SATISFACTORY TO THE ISSUER OF THESE SECURITIES, SUCH OFFER, SALE OR TRANSFER, PLEDGE OR HYPOTHECATION IS IN COMPLIANCE THEREWITH.

5 US-DOCS\140855887.2 THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO CERTAIN RESTRICTIONS ON TRANSFER AND RIGHT OF FIRST REFUSAL OPTIONS HELD BY THE ISSUER OR ITS ASSIGNEE(S) AS SET FORTH IN THE RESTRICTED STOCK UNIT AGREEMENT BETWEEN THE ISSUER AND THE ORIGINAL HOLDER OF THESE SHARES, A COPY OF WHICH MAY BE OBTAINED AT THE PRINCIPAL OFFICE OF THE ISSUER. SUCH TRANSFER RESTRICTIONS AND RIGHT OF FIRST REFUSAL ARE BINDING ON TRANSFEREES OF THESE SHARES. (b) Stop-Transfer Notices. Participant agrees that, in order to ensure compliance with the restrictions set forth herein, the Company may issue appropriate “stop transfer” instructions to its transfer agent, if any, and that, if the Company transfers its own securities, it may make appropriate notations to the same effect in its own records. (c) Refusal to Transfer. The Company shall not be required (i) to transfer on its books any Shares that have been sold or otherwise transferred in violation of any of the provisions of this Agreement or (ii) to treat as owner of such Shares or to accord the right to vote or pay dividends to any purchaser or other transferee to whom such Shares shall have been so transferred. 4.4 Adjustments. Participant acknowledges that the RSUs and the Shares subject to the RSUs are subject to adjustment, modification and/or termination in certain events as provided in this Agreement and the Plan. 4.5 Clawback. The Award and the Shares issuable hereunder shall be subject to any Company clawback or recoupment policy in effect on the Grant Date or as may be adopted or maintained by the Company following the Grant Date, including the Dodd-Frank Wall Street Reform and Consumer Protection Act and any rules or regulations promulgated thereunder. 4.6 Notices. Any notice to be given under the terms of this Agreement to the Company must be in writing and addressed to the Company in care of the Company’s General Counsel at the Company’s principal office or the General Counsel’s then-current email address or facsimile number. Any notice to be given under the terms of this Agreement to Participant must be in writing and addressed to Participant (or, if Participant is then deceased, to the Designated Beneficiary) at Participant’s last known mailing address, email address or facsimile number in the Company’s personnel files. By a notice given pursuant to this Section, either party may designate a different address for notices to be given to that party. Any notice will be deemed duly given when actually received, when sent by email, when sent by certified mail (return receipt requested) and deposited with postage prepaid in a post office or branch post office regularly maintained by the United States Postal Service, when delivered by a nationally recognized express shipping company or upon receipt of a facsimile transmission confirmation. 4.7 Titles. Titles are provided herein for convenience only and are not to serve as a basis for interpretation or construction of this Agreement. 4.8 Conformity to Securities Laws. Participant acknowledges that the Plan, the Grant Notice and this Agreement are intended to conform to the extent necessary with all Applicable Laws and, to the extent Applicable Laws permit, will be deemed amended as necessary to conform to Applicable Laws. 4.9 Successors and Assigns. The Company may assign any of its rights under this Agreement to a single or multiple assignees, and this Agreement will inure to the benefit of the successors and assigns of the Company. Subject to the restrictions on transfer set forth in this Agreement or the Plan, this

6 US-DOCS\140855887.2 Agreement will be binding upon and inure to the benefit of the heirs, legatees, legal representatives, successors and assigns of the parties hereto. 4.10 Limitations Applicable to Section 16 Persons. Notwithstanding any other provision of the Plan or this Agreement, if Participant is subject to Section 16 of the Exchange Act, the Plan, the Grant Notice, this Agreement and the RSUs will be subject to any additional limitations set forth in any applicable exemptive rule under Section 16 of the Exchange Act (including any amendment to Rule 16b-3) that are requirements for the application of such exemptive rule. To the extent Applicable Laws permit, this Agreement will be deemed amended as necessary to conform to such applicable exemptive rule. 4.11 Entire Agreement; Amendment. The Plan, the Grant Notice and this Agreement (including any exhibit hereto) constitute the entire agreement of the parties and supersede in their entirety all prior undertakings and agreements of the Company and Participant with respect to the subject matter hereof. To the extent permitted by the Plan, this Agreement may be wholly or partially amended or otherwise modified, suspended or terminated at any time or from time to time by the Administrator or the Board; provided, however, that except as may otherwise be provided by the Plan, no amendment, modification, suspension or termination of this Agreement shall materially and adversely affect the RSUs without the prior written consent of Participant. 4.12 Agreement Severable. In the event that any provision of the Grant Notice or this Agreement is held illegal or invalid, the provision will be severable from, and the illegality or invalidity of the provision will not be construed to have any effect on, the remaining provisions of the Grant Notice or this Agreement. 4.13 Limitation on Participant’s Rights. Participation in the Plan confers no rights or interests other than as herein provided. This Agreement creates only a contractual obligation on the part of the Company as to amounts payable and may not be construed as creating a trust. Neither the Plan nor any underlying program, in and of itself, has any assets. Participant will have only the rights of a general unsecured creditor of the Company with respect to amounts credited and benefits payable, if any, with respect to the RSUs, and rights no greater than the right to receive cash or the Shares as a general unsecured creditor with respect to the RSUs, as and when settled pursuant to the terms of this Agreement. 4.14 Not a Contract of Employment. Nothing in the Plan, the Grant Notice or this Agreement confers upon Participant any right to continue in the service of the Company or any Subsidiary or interferes with or restricts in any way the rights of the Company and its Subsidiaries, which rights are hereby expressly reserved, to discharge or terminate the services of Participant at any time for any reason whatsoever, with or without cause, except to the extent expressly provided otherwise in a written agreement between the Company or a Subsidiary and Participant. 4.15 Counterparts. The Grant Notice may be executed in one or more counterparts, including by way of any electronic signature, subject to Applicable Law, each of which will be deemed an original and all of which together will constitute one instrument. 4.16 Code Section 409A. Section 409A. To the extent applicable, this Agreement shall be interpreted in accordance with Section 409A of the Code and Department of Treasury regulations and other interpretive guidance issued thereunder (“Section 409A”), including without limitation any such regulations or other guidance that may be issued after the Grant Date. Notwithstanding any other provision of the Plan, the Notice or this Agreement, if at any time the Administrator determines that the RSUs (or any portion thereof) may be subject to Section 409A, the Administrator shall have the right in its sole discretion (without any obligation to do so or to indemnify Participant or any other person for failure to do so) to adopt such amendments to the Plan, the Notice or this Agreement, or adopt other policies and procedures (including

7 US-DOCS\140855887.2 amendments, policies and procedures with retroactive effect), or take any other actions, as the Administrator determines are necessary or appropriate for the RSUs to be exempt from the application of Section 409A or to comply with the requirements of Section 409A. For purposes of this Agreement, a termination of employment or service will be determined consistent with the rules relating to a “separation from service” as defined in Section 409A. Payments pursuant to this section are intended to constitute separate payments for purposes of Section 1.409A-2(b)(2) of the Treasury Regulations. Notwithstanding anything to the contrary in this Agreement, no amounts shall be paid to Participant under this Agreement during the six-month period following Participant’s “separation from service”, as defined in Section 409A, to the extent that the Administrator determines that Participant is a “specified employee” (within the meaning of Section 409A) at the time of such separation from service and that paying such amounts at the time or times indicated in this Agreement would be a prohibited distribution under Section 409A(a)(2)(B)(i) of the Code. If the payment of any such amounts is delayed as a result of the previous sentence, then on the first business day following the end of such six-month period (or such earlier date upon which such amount can be paid under Section 409A without being subject to such additional taxes), the Company shall pay to Participant in a lump-sum all amounts that would have otherwise been payable to Participant during such six-month period under this Agreement. * * * * *

8 US-DOCS\140855887.2 EXHIBIT B INVESTMENT REPRESENTATION STATEMENT PARTICIPANT: COMPANY : ABP SUB, INC. SECURITY : COMMON STOCK AMOUNT : DATE : In connection with the receipt of the above-listed shares of Common Stock of ABP Sub, Inc. (the “Company”), the undersigned (“Participant”) represents to the Company the following: (a) Participant is aware of the Company’s business affairs and financial condition and has acquired sufficient information about the Company to reach an informed and knowledgeable decision to acquire the Securities. Participant is acquiring these Securities for investment for Participant’s own account only and not with a view to, or for resale in connection with, any “distribution” thereof within the meaning of the Securities Act of 1933, as amended (the “Securities Act”). (b) Participant acknowledges and understands that the Securities constitute “restricted securities” under the Securities Act and have not been registered under the Securities Act in reliance upon a specific exemption therefrom, which exemption depends upon, among other things, the bona fide nature of Participant’s investment intent as expressed herein. Participant further understands that the Securities must be held indefinitely unless they are subsequently registered under the Securities Act or an exemption from such registration is available. Participant further acknowledges and understands that the Company is under no obligation to register the Securities. Participant understands that the certificate evidencing the Securities will be imprinted with a legend which prohibits the transfer of the Securities unless they are registered or such registration is not required in the opinion of counsel satisfactory to the Company and any other legend required under applicable state securities laws. (c) Participant is familiar with the provisions of Rule 701 and Rule 144, each promulgated under the Securities Act, which, in substance, permit limited public resale of “restricted securities” acquired, directly or indirectly from the issuer thereof, in a non-public offering subject to the satisfaction of certain conditions. In the event the Company becomes subject to the reporting requirements of Section 13 or 15(d) of the Securities Exchange Act of 1934, ninety (90) days thereafter (or such longer period as any market stand-off agreement may require) the Securities exempt under Rule 701 may be resold, subject to the satisfaction of certain of the conditions specified by Rule 144, including: (1) the resale being made through a broker in an unsolicited “broker’s transaction” or in transactions directly with a market maker (as said term is defined under the Securities Exchange Act of 1934); and, in the case of an affiliate, (2) the availability of certain public information about the Company, (3) the amount of Securities being sold during any three (3) month period not exceeding the limitations specified in Rule 144(e), and (4) the timely filing of a Form 144, if applicable. In the event that the Company does not qualify under Rule 701 at the time of grant of the RSU, then the Securities may be resold in certain limited circumstances subject to the provisions of Rule 144, which requires the resale to occur not less than one year after the later of the date the Securities were sold by the Company or the date the Securities were sold by an affiliate of the Company (for non-

9 US-DOCS\140855887.2 reporting companies), within the meaning of Rule 144; and, in the case of acquisition of the Securities by an affiliate, or by a non-affiliate who subsequently holds the Securities less than one (1) year, the satisfaction of the conditions set forth in sections (1), (2), (3) and (4) of the paragraph immediately above. (d) Participant further understands that in the event all of the applicable requirements of Rule 701 or 144 are not satisfied, registration under the Securities Act, compliance with Regulation A, or some other registration exemption will be required; and that, notwithstanding the fact that Rules 144 and 701 are not exclusive, the Staff of the Securities and Exchange Commission has expressed its opinion that persons proposing to sell private placement securities other than in a registered offering and otherwise than pursuant to Rules 144 or 701 will have a substantial burden of proof in establishing that an exemption from registration is available for such offers or sales, and that such persons and their respective brokers who participate in such transactions do so at their own risk. Participant understands that no assurances can be given that any such other registration exemption will be available in such event. (e) Participant understands and acknowledges that the Company will rely upon the accuracy and truth of the foregoing representations and Participant hereby consents to such reliance.
