Surviving Pubco Class A Shares that may be issued as Earnout Shares[, and any Exchange Shares] (all such securities, together with any

securities paid as dividends or distributions with respect to such securities or into which such securities are exchanged or converted

but, for the avoidance of doubt, not including any shares issued in connection with the PIPE Investment Subscription Agreements, the

“Restricted Securities”), shall become subject to limitations on disposition as set forth herein.




 











     



     



    



 




NOW,

THEREFORE, in consideration of the premises set forth above, which are incorporated in this Agreement as if fully set forth below,

and intending to be legally bound hereby, the parties hereby agree as follows:




 




1.

Lock-Up Provisions.




 




(a)

Holder hereby agrees not to, without the prior written consent of Purchaser, during the period commencing from the Closing and ending

on the earlier of (x) 180 days after the date of the Closing and (y) the date after the Closing on which Purchaser consummates a liquidation,

merger, stock exchange, reorganization, tender offer, or other similar transaction that results in all of Purchaser’s stockholders

having the right to exchange their equity holdings in Purchaser for cash, securities or other property (such period, the “Lock-Up

Period”): (i) lend, offer to sell, donate, assign, sell, contract to sell, sell any option or contract to purchase, purchase

any option or contract to sell, grant any option, right or warrant to purchase, or otherwise transfer or dispose of, directly or indirectly,

any Restricted Securities owned by Holder, (ii) enter into any swap or other arrangement that transfers to another, in whole or

in part, any of the economic consequences of ownership of the Restricted Securities owned by Holder, or (iii) publicly disclose

the intention to do any of the foregoing, whether any such transaction described in clauses (i), (ii) or (iii) above is to be settled

by delivery of Restricted Securities or other securities, in cash or otherwise (any of the foregoing described in clauses (i), (ii) or

(iii), a “Prohibited Transfer”). The foregoing sentence shall not apply to the transfer of any or all of the

Restricted Securities owned by Holder (I) by gift, will or intestate succession upon the death of Holder, (II) to any Permitted Transferee

(as defined below), (III) by operation of law, pursuant to a court order or settlement agreement related to the distribution of assets

in connection with the dissolution of marriage or civil union, (IV) pursuant to any hypothecation or pledge securing a loan, or (V) in

connection with Purchaser’s consummation of a liquidation, merger, stock exchange, reorganization, tender offer or other similar

transaction that results in all of Purchaser’s stockholders having the right to exchange their equity holdings in Purchaser for

cash, securities or other property; provided, however, that in any of cases (I), (II) or (III) it shall be a condition

to such transfer that the transferee executes and delivers to the Purchaser and the Company an agreement stating that the transferee

is receiving and holding the Restricted Securities subject to the provisions of this Agreement applicable to Holder, and there shall

be no further transfer of such Restricted Securities except in accordance with this Agreement. As used in this Agreement, the term “Permitted

Transferee” shall mean: (A) the members of Holder’s immediate family (for purposes of this Agreement, “immediate

family” shall mean with respect to any natural person, any of the following: such person’s spouse or domestic partner, the

siblings of such person and his or her spouse or domestic partner, and the direct descendants and ascendants (including adopted and step

children and parents) of such person and his or her spouse or domestic partner and siblings), (B) any trust for the direct or indirect

benefit of Holder or the immediate family of Holder, (C) if Holder is a trust, the trustor or beneficiary of such trust or the estate

of a beneficiary of such trust, (D) if Holder is an entity, as a distribution to limited partners, shareholders, members of, or owners

of similar equity interests in Holder, and (E) any Affiliate of Holder or any employees, officers, directors or members of Holder or

any Affiliates of Holder. Holder further agrees to execute such agreements as may be reasonably requested by Purchaser or the Company

that are consistent with the foregoing and necessary to give further effect thereto.




 




(b)

[For the avoidance of doubt, there shall be no exchanges of Class B Units pursuant to the Exchange Policy until after expiration of the

Lock-Up Period under this Agreement.]




 




(c)

If any Prohibited Transfer is made or attempted contrary to the provisions of this Agreement, such purported Prohibited Transfer shall

be null and void ab initio, and Purchaser shall refuse to recognize any such purported transferee of the Restricted Securities as one

of its equity holders for any purpose. In order to enforce this Section 1, Purchaser may impose stop-transfer instructions

with respect to the Restricted Securities of Holder (and Permitted Transferees and assigns thereof) until the end of the Lock-Up Period,

except in compliance with the foregoing exceptions.




 











    2



     



    



 




(d)

During the Lock-Up Period, each certificate evidencing any Restricted Securities shall be stamped or otherwise imprinted with a legend

in substantially the following form, in addition to any other applicable legends:




 




“THE

SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO RESTRICTIONS ON TRANSFER SET FORTH IN A LOCK-UP AGREEMENT, DATED AS OF [●], 2021, BY AND AMONG THE ISSUER OF SUCH SECURITIES (THE “ISSUER”), A CERTAIN REPRESENTATIVE OF THE ISSUER NAMED THEREIN

AND THE ISSUER’S SECURITY HOLDER NAMED THEREIN, AS AMENDED. A COPY OF SUCH LOCK-UP AGREEMENT WILL BE FURNISHED WITHOUT CHARGE BY

THE ISSUER TO THE HOLDER HEREOF UPON WRITTEN REQUEST.”




 




Promptly

upon the expiration of the Lock-Up Period, Purchase will make best efforts to remove such legend from the certificates evidencing the

Restricted Securities.




 




(e)

For the avoidance of doubt, (i) Holder shall retain all of its rights as a shareholder of the Purchaser during the Lock-Up Period, including

the right to vote any Restricted Securities and to receive any dividends and distributions in respect of any Restricted Securities, and

(ii) the restrictions contained in Section 1(a) shall not apply to any Surviving Pubco Class A Shares, Class B Units, Surviving Pubco

Class V Shares or other securities of the Company acquired by Holder in open market transactions or in any public or private capital

raising transactions of the Company or otherwise to any Surviving Pubco Class A Shares, Class B Units, Surviving Pubco Class V Shares

or other securities of the Company (other than the Restricted Securities). Prior to or at the Closing, the Company shall execute and

deliver to the Purchaser the Registration Rights Agreement and allow Holder the opportunity to be a party to the Registration Rights

Agreement entitled to the registration rights thereunder.




 




2.

Miscellaneous.




 




(a)

Termination of Merger Agreement. This Agreement shall be binding upon Holder upon Holder’s execution and delivery of this

Agreement, but this Agreement shall only become effective upon the Closing. Notwithstanding anything to the contrary contained herein,

in the event that the Merger Agreement is terminated in accordance with its terms prior to the Closing, this Agreement and all rights

and obligations of the parties hereunder shall automatically terminate and be of no further force or effect.




 




(b)

Binding Effect; Assignment. This Agreement and all of the provisions hereof shall be binding upon and inure to the benefit of

the parties hereto and their respective permitted successors and assigns. This Agreement and all obligations of Holder are personal to

Holder and may not be transferred or delegated by Holder at any time without the prior written consent of the Purchaser and the Company.

Each of the Purchaser and the Company may freely assign any or all of its rights under this Agreement, in whole or in part, to any successor

entity (whether by merger, consolidation, equity sale, asset sale or otherwise) without obtaining the consent or approval of Holder.




 




(c)

Third Parties. Nothing contained in this Agreement or in any instrument or document executed by any party in connection with the

transactions contemplated hereby shall create any rights in, or be deemed to have been executed for the benefit of, any person or entity

that is not a party hereto or thereto or a successor or permitted assign of such a party.




 











    3



     



    



 




(d)

Governing Law; Waiver of Jury Trial; Jurisdiction. This Agreement and all related claims or causes of action shall be governed

by and construed in accordance with the internal Laws of the State of Delaware, without giving effect to any choice of law or conflict

of law provision or rule (whether of the State of Delaware or any other jurisdiction) that would cause the application of the Law of

any jurisdiction other than the State of Delaware. EACH PARTY HERETO HEREBY WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW, ANY RIGHT

TO TRIAL BY JURY OF ANY CLAIM, DEMAND, ACTION, OR CAUSE OF ACTION (I) ARISING UNDER THIS AGREEMENT OR (II) IN ANY WAY CONNECTED WITH

OR RELATED OR INCIDENTAL TO THE DEALINGS OF THE PARTIES HERETO IN RESPECT OF THIS AGREEMENT OR ANY OF THE TRANSACTIONS RELATED HERETO,

IN EACH CASE WHETHER NOW EXISTING OR HEREAFTER ARISING, AND WHETHER IN CONTRACT, TORT, EQUITY, OR OTHERWISE. THE PARTIES HERETO EACH

HEREBY AGREE AND CONSENT THAT ANY SUCH CLAIM, DEMAND, ACTION, OR CAUSE OF ACTION SHALL BE DECIDED BY COURT TRIAL WITHOUT A JURY AND THAT

THE PARTIES HERETO MAY FILE AN ORIGINAL COUNTERPART OF A COPY OF THIS AGREEMENT WITH ANY COURT AS WRITTEN EVIDENCE OF THE CONSENT OF

THE PARTIES HERETO TO THE WAIVER OF THEIR RIGHT TO TRIAL BY JURY. Sections 12.7 and 12.14 of the Merger Agreement shall apply to this

Agreement mutatis mutandis with references to the Merger Agreement therein deemed to reference this Agreement and references to the “Parties”

thereunder deemed to reference the parties hereto.




 




(e)

Interpretation. The titles and subtitles used in this Agreement are for convenience only and are not to be considered in construing

or interpreting this Agreement. In this Agreement, unless the context otherwise requires: (i) any pronoun used in this Agreement shall

include the corresponding masculine, feminine or neuter forms, and the singular form of nouns, pronouns and verbs shall include the plural

and vice versa; (ii) “including” (and with correlative meaning “include”) means including without limiting the

generality of any description preceding or succeeding such term and shall be deemed in each case to be followed by the words “without

limitation”; (iii) the words “herein,” “hereto,” and “hereby” and other words of similar import

shall be deemed in each case to refer to this Agreement as a whole and not to any particular section or other subdivision of this Agreement;

and (iv) the term “or” means “and/or”. The parties have participated jointly in the negotiation and drafting

of this Agreement. Consequently, in the event an ambiguity or question of intent or interpretation arises, this Agreement shall be construed

as if drafted jointly by the parties hereto, and no presumption or burden of proof shall arise favoring or disfavoring any party by virtue

of the authorship of any provision of this Agreement.




 




(f)

Notices. All notices, consents, waivers and other communications hereunder shall be in writing and shall be deemed to have been

duly given when delivered (i) in person, (ii) by email during normal business hours, (iii) by FedEx or other nationally recognized overnight

courier service, or (iv) after posting in the United States mail having been sent registered or certified mail return receipt requested,

postage prepaid, and otherwise on the next Business Day, addressed as follows (or at such other address for a party as shall be specified

by like notice):

(g)

Amendments and Waivers. Any term of this Agreement may be amended and the observance of any term of this Agreement may be waived

(either generally or in a particular instance, and either retroactively or prospectively) only with the written consent of the Purchaser,

the Company and Holder. No failure or delay by a party in exercising any right hereunder shall operate as a waiver thereof. No waivers

of or exceptions to any term, condition, or provision of this Agreement, in any one or more instances, shall be deemed to be or construed

as a further or continuing waiver of any such term, condition, or provision. Purchaser and the Company hereby represent, warrant, covenant

and agree that (i) if any Lock-Up Agreement signed by an interestholder of the Company in connection with the transactions contemplated

hereby is amended, modified or waived in a manner favorable to such interestholder and that would be favorable to Holder, this Agreement

shall be contemporaneously amended in the same manner and Purchaser shall provide prompt notice thereof to Holder, and (ii) if any such

interestholder is released from any or all of the lock-up restrictions under its Lock-Up Agreement, Holder will be similarly and contemporaneously

released from the lock-up restrictions hereunder (which, for the avoidance, of doubt will include a release of the same percentage of

Holder’s Restricted Securities) and Purchaser shall provide prompt notice thereof to Holder.




 




(h)

Severability. In case any provision in this Agreement shall be held invalid, illegal or unenforceable in a court of competent

jurisdiction, such provision shall be modified or deleted, as to the jurisdiction involved, only to the extent necessary to render the

same valid, legal and enforceable, and the validity, legality and enforceability of the remaining provisions hereof shall not in any

way be affected or impaired thereby nor shall the validity, legality or enforceability of such provision be affected thereby in any other

jurisdiction. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the parties

will substitute for any invalid, illegal or unenforceable provision a suitable and equitable provision that carries out, so far as may

be valid, legal and enforceable, the intent and purpose of such invalid, illegal or unenforceable provision.




 











    5



     



    



 




(i)

Specific Performance. Holder acknowledges that its obligations under this Agreement are unique, recognizes and affirms that in

the event of a breach of this Agreement by Holder, money damages will be inadequate and Purchaser and the Company will have no adequate

remedy at law, and agrees that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed

by Holder in accordance with their specific terms or were otherwise breached. Accordingly, each of the Purchaser and the Company shall

be entitled to an injunction or restraining order to prevent breaches of this Agreement by Holder and to enforce specifically the terms

and provisions hereof, without the requirement to post any bond or other security or to prove that money damages would be inadequate,

this being in addition to any other right or remedy to which such party may be entitled under this Agreement, at law or in equity.




 




(j)

Entire Agreement. This Agreement constitutes the full and entire understanding and agreement among the parties with respect to

the subject matter hereof, and any other written or oral agreement relating to the subject matter hereof existing between the parties

is expressly canceled; provided, that, for the avoidance of doubt, the foregoing shall not affect the rights and obligations

of the parties under the Merger Agreement or any Ancillary Agreement. Notwithstanding the foregoing, nothing in this Agreement shall

limit any of the rights or remedies of the Purchaser and the Company or any of the obligations of Holder under any other agreement between

Holder and the Purchaser or the Company or any certificate or instrument executed by Holder in favor of the Purchaser or the Company,

and nothing in any other agreement, certificate or instrument shall limit any of the rights or remedies of the Purchaser or the Company

or any of the obligations of Holder under this Agreement.




 




(k)

Further Assurances. From time to time, at the other party’s request and without further consideration (but at the requesting

party’s reasonable cost and expense), each party shall execute and deliver such additional documents and take all such further

action as may be reasonably necessary to consummate the transactions contemplated by this Agreement.




 




(l)

Counterparts; Facsimile. This Agreement may be executed in multiple counterparts (including by facsimile or pdf or other

electronic document transmission), each of which shall be deemed an original, and all of which taken together shall constitute one and

the same instrument.
