1.9 Vesting and Forfeiture Provisions.

(a) No Transfer of Subject Shares. Each Sponsor Party agrees that, on the Closing Date, all of the Subject Shares (and not, for the avoidance of doubt, any other Parent Common Shares acquired or purchased by such Sponsor Party, whether pursuant to the Sponsor Backstop Subscription Agreement, or otherwise) held of record by such Sponsor Party as of the Closing shall be subject to the vesting and forfeiture provisions set forth in this Section 1.9. Each Sponsor Party agrees that it shall not directly or indirectly Transfer any Subject Shares held of record by such Sponsor Party prior to the date such Subject Shares become vested pursuant to this Section 1.9.

(b) Vesting and Forfeiture of Subject Shares.

(i) In the event (x) there are no Parent Stockholder Redemptions or (y) no Backstop Shares (as defined in the Sponsor Backstop Subscription Agreement) are purchased at the Closing pursuant to the Sponsor Backstop Subscription Agreement, the Subject Shares held of record by each Sponsor Party shall vest and no longer be subject to forfeiture as follows:

(A) 40% of such Subject Shares (i.e., 2,750,000 Subject Shares held of record in the aggregate by all Sponsor Parties at the Closing) shall vest upon the occurrence of a Triggering Event I;

(B) 40% of such Subject Shares (i.e., 2,750,000 Subject Shares held of record in the aggregate by all Sponsor Parties at the Closing) shall vest upon the occurrence of a Triggering Event II; and

(C) 20% of such Subject Shares (i.e., 1,375,000 Subject Shares held of record in the aggregate by all Sponsor Parties at the Closing) shall vest upon the occurrence of a Triggering Event III.

(ii) In the event the Sponsor Backstop Amount is greater than zero (0), the Subject Shares held of record by each Sponsor Party shall vest or forfeit as follows:

(A) a number of such Subject Shares equal to the product of (x) 50% multiplied by (y) the quotient of (1) the Sponsor Backstop Amount divided by (2) $50,000,000, shall vest and no longer be subject to forfeiture (except pursuant to Section 1.9(b)(iii)) at the Closing (provided, that such number shall be capped at (A) 50% of the Subject Shares held of record by such Sponsor Party at the Closing and (B) 3,437,500 Subject Shares held of record in the aggregate by all Sponsor Parties at the Closing);

-4-

(B) to the extent the Parent Stockholder Redemption Amount is greater than the Sponsor Backstop Amount, (such difference, capped at a maximum amount of $200,000,000, the “Excess Amount”), a number of such Subject Shares equal to the product of (x) 50% multiplied by (y) the quotient of (1) the Excess Amount divided by (2) $200,000,000, shall not vest and shall be forfeited as of immediately prior to the Closing as provided in Section 1.9(d) below (provided, that such number shall be capped at (A) 50% of the Subject Shares held of record by such Sponsor Party at the Closing and (B) 3,437,500 Subject Shares held of record in the aggregate by all Sponsor Parties at the Closing); and

(C) with respect to any Subject Shares that do not vest in accordance with Section 1.9(b)(ii)(A) or are not forfeited in accordance with Section 1.9(b)(ii)(B) (such shares, the “Remaining Subject Shares”) shall vest and no longer be subject to forfeiture as follows:

(1) 40% of the Remaining Subject Shares shall vest upon the occurrence of a Triggering Event I;

(2) 40% of the Remaining Subject Shares shall vest upon the occurrence of a Triggering Event II; and

(iii) In the event that, at the Closing, the Unpaid Parent Expenses exceed the sum of (x) the Additional Parent Cash, plus (y) $20,000,000 (the amount of such excess, the “Expenses Excess Amount”), then a number of Subject Shares in the aggregate equal to the quotient of (i) the Expenses Excess Amount divided by (ii) $10.00 (which shall be equitably adjusted for stock splits, reverse stock splits, stock dividends, reorganizations, recapitalizations, reclassifications, combination, exchange of shares or other like change or transaction with respect to Parent Common Stock occurring prior to the Effective Time) shall be forfeited as of immediately prior to the Closing as provided in Section 1.9(d) below, with each Sponsor Party bearing its pro rata amount (based on the number of Subject Shares held of record by such Sponsor Party relative to the number of Subject Shares held of record by all the Sponsor Parties) of such forfeiture; provided, that (x) any such forfeiture shall be applied first from the Remaining Subject Shares, and the balance of such forfeiture shall be applied to the Subject Shares vested pursuant to Section 1.9(b)(ii)(A) and (y) before any such forfeiture shall be applied, the Sponsor and/or the Sponsor Parties shall be permitted to pay such Expenses Excess Amount in cash prior to or concurrently with the Closing without further liability to Parent or any of its Subsidiaries (in which case, the Expenses Excess Amount shall be reduced on a dollar-for-dollar basis by the amount paid or to be paid by Sponsor and/or the Sponsor Parties prior to or concurrently with the Closing).

(iv) For the avoidance of doubt, for all purposes of this Section 1.9, (i) each Triggering Event shall only occur once, if at all and (ii) multiple Triggering Events may occur at the same time. For illustrative purposes only, in the event the Sponsor Backstop Amount is zero (0) and a Triggering Event III occurs (with no previous Triggering Event having occurred), then a Triggering Event I and Triggering Event II shall also have occurred, and 100% of each Sponsor Party’s Subject Shares shall vest upon the occurrence of such Triggering Events. Notwithstanding anything herein to the contrary, if, during the Earn Out Period, there is a Change of Control, then immediately prior to the consummation of such Change of Control: (a) any Triggering Event that has not previously occurred shall be deemed to have occurred; and (b) all unvested Subject Shares shall vest and all Subject Shares shall be eligible to participate

-5-

in such Change of Control. Notwithstanding anything herein or in the Merger Agreement to the contrary, for all purposes of this Sponsor Agreement, the Parent Stockholder Redemption Amount shall be calculated on the basis that the amount paid with respect to each share of Parent Common Stock in connection with all Parent Stockholder Redemptions is $10.00 (which shall be equitably adjusted for stock splits, reverse stock splits, stock dividends, reorganizations, recapitalizations, reclassifications, combination, exchange of shares or other like change or transaction with respect to Parent Common Stock occurring prior to the Effective Time). Notwithstanding anything in this Section 1.9 to the contrary, references to specific numbers of Subject Shares in this Section 1.9 shall be equitably adjusted for stock splits, reverse stock splits, stock dividends, reorganizations, recapitalizations, reclassifications, combination, exchange of shares or other like change or transaction with respect to Parent Common Stock occurring from time to time.

(v) Upon the expiration of the Earn-Out Period, any Subject Shares or Remaining Subject Shares, as applicable, that have not vested as of such time shall be forfeited in accordance with Section 1.9(d).

(c) Forfeiture of Subject Warrants.

(i) The Sponsor shall forfeit 2,166,667 Subject Warrants as of immediately prior to the Closing as provided in Section 1.9(d) below. In addition, if the Excess Amount is greater than zero (0), the Sponsor shall forfeit as of immediately prior to the Closing as provided in Section 1.9(d) below a number of additional Subject Warrants equal to the product of (x) 1,500,000 multiplied by (y) the quotient of (A) the Excess Amount divided by (B) $200,000,000 (provided, that such number shall be capped at 1,500,000 of the Subject Warrants held of record by such Sponsor at the Closing). For purposes of this Agreement, “Remaining Subject Warrants” shall mean any Subject Warrants not forfeited pursuant to this Section 1.9(c)(i).

(ii) Notwithstanding the terms of the Warrant Agreement, dated December 8, 2020, among Parent and American Stock Transfer & Trust Company, LLC, as warrant agent (the “Sponsor Warrant Agreement”), if at any time following the Closing a Triggering Event IV occurs, then Parent shall thereafter be entitled to provide written notice to the Sponsor requiring the Sponsor to exercise not less than all of the Remaining Subject Warrants. Any such exercise shall take place within thirty (30) days of receipt of the written notice from Parent specified in the foregoing sentence and the Subject Warrants shall be exercisable for cash or on a “cashless basis” (at the election of the Sponsor) in accordance with the provisions of the Sponsor Warrant Agreement. For purposes of this Agreement, a “Triggering Event IV” means that the VWAP of Parent Class A Common Stock is, at any time following the Closing, greater than or equal to $18.00 over any twenty (20) Trading Days within any thirty (30) Trading Day period (which shall be equitably adjusted for stock splits, reverse stock splits, stock dividends, reorganizations, recapitalizations, reclassifications, combination, exchange of shares or other like change or transaction with respect to Parent Class A Common Stock occurring on or after the Closing).

(d) Forfeiture Procedures. Notwithstanding the provisions of Section 1.2, Subject Shares and Subject Warrants that are forfeited pursuant to this Section 1.9(d), shall, as of the applicable time, be deemed to have been automatically and irrevocably surrendered, assigned and Transferred by the applicable forfeiting Sponsor Party to Parent without any consideration for such Transfer and Parent shall cancel such shares and/or warrants without any further action or consent of such forfeiting Sponsor Party. Parent and the applicable Sponsor Party shall take all action as reasonably requested by Parent (including by executing and delivering any agreements, instruments, certificates or powers of attorney) in order to effect such forfeiture, and otherwise to reflect the assignment, Transfer and recapture of such shares by Parent, without any consideration, and to vest Parent with full right, title and possession of such shares. Each Sponsor Party agrees that Parent and American Stock Transfer & Trust Company, LLC, as transfer agent for the Company or warrant agent, as applicable, and any successor thereto, shall be entitled to rely conclusively on the terms of this Agreement in connection with taking any such action necessary or advisable in connection with such forfeiture, including by amending and restating the Sponsor Warrant Agreement.

-6-

(e) Allocation of Vesting and Forfeiture. Notwithstanding anything in this Section 1.9 to the contrary, in connection with any vesting or forfeiture of any Subject Shares and Subject Warrants pursuant to this Section 1.9, the Sponsor shall be entitled to allocate the amount of any such vesting or forfeiture in any manner among the Sponsor Parties provided that such allocation does not increase or reduce the aggregate amount of such Subject Shares and Subject Warrants subject to vesting or forfeiture.

(f) Voting and Dividends. Each Sponsor Party shall be entitled to vote its unvested Subject Shares and receive dividends and other distributions (whether payable in the form of cash, stock or other assets), and to have all other economic rights (including, without limitation, the right to receive any consideration payable upon conversion or exchange), in each case, with respect to such Subject Shares or Remaining Subject Shares, as applicable, while they remain unvested.

(g) Voting Letter Agreement. With effect at the Closing, the provisions in this Section 1.9 shall supersede the lock-up provisions contained in Section and 7(a) of the Voting Letter Agreement, which provisions in such letter agreement shall be of no further force or effect.

1.10 Waiver of Adjustment Provisions. Notwithstanding anything to the contrary in any other document, agreement or contract to which a Sponsor Party is bound, but subject in all cases to the vesting and forfeiture provisions of Section 1.9, each Sponsor Party (for itself, himself or herself and for its, his or her successors, heirs, assigns and permitted transferees) hereby (but subject to the consummation of the Merger) irrevocably and unconditionally waives and agrees not to exercise or assert, any rights to adjustment or other anti-dilution protections with respect to the rate at which shares of Parent Class B Common Stock convert into shares of Parent Class A Common Stock in connection with the transactions contemplated by the Merger Agreement and, in furtherance of the foregoing, each Sponsor Party hereby agrees and acknowledges that each share of Parent Class B Common Stock shall convert into shares of Parent Class A Common Stock on a one-for-one basis automatically upon the occurrence of the Effective Time, such waiver, agreement and acknowledgement constituting sufficient and necessary waiver under the terms of Parent’s Certificate of Incorporation (the “Parent Charter”) to waive any and all adjustments to the Initial Conversion Ratio (as defined in the Parent Charter) in connection with, and subject to, the consummation of the Merger.

1.11 Permitted Transfers. Notwithstanding the provisions set forth in Sections 1.2 and 1.9, each Sponsor Party may make Transfers of shares of Parent Common Stock, Parent Warrants and shares of Parent Common Stock issued or issuable upon the exercise or conversion of the Parent Warrants (i) to (A) Parent’s or the Sponsor’s officers or directors, or (B) any Affiliate of such Sponsor Party, including any related investment funds or vehicles controlled or managed by the Sponsor Parties or their respective Affiliates (provided, that no Transfer pursuant to this clause (B) shall be permitted to any limited partners in such related investment funds); (ii) in the case of an individual, by gift to a member of the individual’s immediate family or to a trust, the beneficiary of which is a member of the individual’s immediate family or an affiliate of such person or entity; (iii) in the case of an individual, by virtue of laws of descent and distribution upon death of the individual; (iv) in the case of an individual, pursuant to a qualified domestic relations order, divorce settlement, divorce decree or separation agreement; (v) to a nominee or custodian of a Person to whom a Transfer would be permitted under clauses (i) through (iv) above; (vii) in connection with any bona fide mortgage, encumbrance, pledge or other grant of a security interest to one or more financial or lending institutions as collateral or security for or in connection with any bona fide loans, advances or extensions of credit or debt transaction (or enforcement thereunder) entered into by such

-7-

Sponsor Party or any of its Affiliates, or any refinancings thereof, and any Transfers upon foreclosure thereof; or (viii) in connection with any legal, regulatory or other order; provided, however, that in the case of the foregoing clauses (i) through (viii) the transferee must enter into a written agreement with the Company agreeing to be bound by this Agreement as a Sponsor Party prior to the effectiveness of such Transfer. Notwithstanding the foregoing, each Sponsor Party shall hold any Subject Shares that have not become vested pursuant to Section 1.9 of record, in its name on the books and records of the Company’s transfer agent.

1.12 No Challenges. Each Sponsor Party agrees not to commence or join in or knowingly facilitate, assist or encourage, and agrees to take all actions necessary to opt out of any class in any class action with respect to, any claim, derivative or otherwise, against Parent, Merger Sub, the Company or any of their respective successors or directors (except in any case arising out of the fraud of willful misconduct of such parties), (a) challenging the validity of, or seeking to enjoin the operation of, any provision of this Agreement or (b) alleging a breach of any fiduciary duty of any Person in connection with the evaluation, negotiation or entry into the Merger Agreement. Notwithstanding the foregoing, nothing herein shall be deemed to prohibit such Sponsor Party from enforcing such Sponsor Party’s rights under this Agreement and the other agreements entered into in by such Sponsor Party in connection herewith.

1.13 Affiliate Agreements. Each Sponsor Party hereby agrees and consents to the termination of the Contracts set forth on Schedule III attached hereto to which such Sponsor Party is party, effective as of the Effective Time without any further liability or obligation to Parent, the Company or their respective Subsidiaries.

Each of the parties hereto hereby irrevocably and unconditionally (a) submits, for itself and its property, to the exclusive jurisdiction of the Delaware Court of Chancery (or, only if the Delaware Court of Chancery declines to accept jurisdiction over a particular matter, the Delaware Supreme Court or the United States District Court for the District of Delaware), and any appellate court from any thereof, in any action or proceeding arising out of or relating to this Sponsor Agreement or the negotiation, execution or performance of this Sponsor Agreement (including any claim or cause of action based upon, arising out of or related to any representation or warranty made in or in connection with this Sponsor Agreement), or for recognition or enforcement of any judgment, and agrees that all claims in respect of any such action or proceeding shall be heard and determined in such Delaware Court of Chancery (or, only if the Delaware Court of Chancery declines to accept jurisdiction over a particular matter, the Delaware Supreme Court or the United States District Court for the District of Delaware), (b) waives, to the fullest extent it may legally and effectively do so, any objection which it may now or hereafter have to the laying of venue of any suit, action or proceeding arising out of or relating to this Sponsor Agreement or the negotiation, execution or performance of this Sponsor Agreement (including any claim or cause of action based upon, arising out of or related to any representation or warranty made in or in connection with this Sponsor Agreement) in the Delaware Court of Chancery or in the Delaware Supreme Court or the United States District Court for the District of Delaware, (c) waives, to the fullest extent permitted by Law, the defense of an inconvenient forum to the maintenance of such action or proceeding in any such court and (d) agrees that a final judgment in any such suit, action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by Law. Each of the parties hereto agrees that service of process, summons, notice or document by registered mail addressed to it at the applicable address set forth in Section 3.8 shall be effective service of process for any suit, action or proceeding brought in any such court.

3.3 Waiver of Jury Trial. THE PARTIES HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVE ANY RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM ARISING OUT OF OR RELATING TO THIS SPONSOR AGREEMENT OR ANY TRANSACTION CONTEMPLATED HEREBY OR THE ACTIONS OF THE PARTIES IN THE

-10-

NEGOTIATION, EXECUTION, PERFORMANCE AND ENFORCEMENT OF THIS SPONSOR AGREEMENT, WHETHER NOW EXISTING OR HEREAFTER ARISING, AND WHETHER SOUNDING IN CONTRACT, TORT OR OTHERWISE. THE PARTIES AGREE THAT ANY OF THEM MAY FILE A COPY OF THIS PARAGRAPH WITH ANY COURT AS WRITTEN EVIDENCE OF THE KNOWING, VOLUNTARY AND BARGAINED FOR AGREEMENT AMONG THE PARTIES IRREVOCABLY TO WAIVE TRIAL BY JURY AND THAT ANY ACTION OR PROCEEDING WHATSOEVER BETWEEN THEM RELATING TO THIS SPONSOR AGREEMENT OR ANY TRANSACTION CONTEMPLATED HEREBY SHALL INSTEAD BE TRIED IN A COURT OF COMPETENT JURISDICTION BY A JUDGE SITTING WITHOUT A JURY.

3.4 Assignment. This Sponsor Agreement and all of the provisions hereof will be binding upon and inure to the benefit of the parties hereto and their respective heirs, successors and permitted assigns. Neither this Sponsor Agreement nor any of the rights, interests or obligations hereunder will be assigned (including by operation of law) without the prior written consent of each of the parties hereto.

3.5 Specific Performance. The parties agree that irreparable damage for which monetary damages, even if available, would not be an adequate remedy, would occur in the event that the parties hereto do not perform the provisions of this Sponsor Agreement in accordance with its specified terms or otherwise breach or threaten to breach such provisions. The parties acknowledge and agree that the parties hereto shall be entitled, in addition to any other remedy to which they are entitled at law or in equity, to an injunction, specific performance and other equitable relief to prevent breaches or threatened breaches of this Sponsor Agreement and to enforce specifically the terms and provisions hereof. Without limiting the foregoing, each of the parties agrees that it will not oppose the granting of an injunction, specific performance and other equitable relief on the basis that (i) there is adequate remedy at law or (ii) an award of specific performance is not an appropriate remedy for any reason at law or in equity. Any party seeking an order or injunction to prevent breaches or threatened breaches and to enforce specifically the terms and provisions of this Sponsor Agreement shall not be required to provide any bond or other security in connection with any such order or injunction.

3.6 Amendment. This Sponsor Agreement may not be amended, changed, supplemented, waived or otherwise modified or terminated, except upon the execution and delivery of a written agreement executed by Parent, the Company and the Sponsor.

3.7 Severability. If any provision of this Sponsor Agreement is held invalid or unenforceable by any court of competent jurisdiction, the other provisions of this Sponsor Agreement will remain in full force and effect. Any provision of this Sponsor Agreement held invalid or unenforceable only in part or degree will remain in full force and effect to the extent not held invalid or unenforceable.

3.8 Notices. All notices and other communications under this Sponsor Agreement shall be in writing and shall be deemed given (a) when delivered personally by hand (with written confirmation of receipt by other than automatic means, whether electronic or otherwise), (b) when sent by email (with no automated reply, such as an out-of-office notification, no mail undeliverable notification or other rejection notice) or (c) one (1) Business Day following the day sent by an internationally recognized overnight courier (with written confirmation of receipt), in each case, at the following addresses or e-mail addresses (or to such other address or e-mail address as a party may have specified by notice given to the other party pursuant to this provision):
