together with the other parties thereto, entering into a definitive Agreement and Plan of Merger (as amended, modified, supplemented or
waived from time to time, the “Transaction Agreement” and the transactions contemplated by the Transaction Agreement

WHEREAS, references herein
to the “Company” shall refer to FirstMark Horizon Acquisition Corp. for all periods prior to completion of the SPAC Merger
and to Holdings (as the surviving corporation in the SPAC Merger) for all periods after completion of the SPAC Merger;


 


WHEREAS, in connection with
the Transactions, and prior to the Closing, Subscriber desires to subscribe for and purchase from the Company that number of shares of
the Company’s Class A common stock, par value $0.0001 per share (the “Class A Common Shares”), set forth on the

and the aggregate of such Per Share Price for all Subscribed Shares being referred to herein as the “Purchase Price”),
and the Company desires to issue and sell to Subscriber the Subscribed Shares in consideration of the payment of the Purchase Price by
or on behalf of Subscriber to the Company; and


 


WHEREAS, on or about the date
of this Subscription Agreement, the Company is entering into (i) subscription agreements (the “Other Subscription Agreements”
and together with this Subscription Agreement, the “Subscription Agreements”) with certain other investors (the “Other
Subscribers” and together with Subscriber, the “Subscribers”), severally and not jointly, in a form substantially
similar to this Subscription Agreement, pursuant to which such Other Subscribers have agreed to purchase, inclusive of the Subscribed

NOW, THEREFORE, in consideration
of the foregoing and the mutual representations, warranties and covenants, and subject to the conditions, herein contained, and intending
to be legally bound hereby, the parties hereto hereby agree as follows:


 


Section 1.Subscription.
Subject to the terms and conditions hereof, at the Closing (as defined below), Subscriber hereby agrees to subscribe for and purchase,
and the Company hereby agrees to issue and sell to Subscriber, upon the payment of the Purchase Price, the Subscribed Shares (such subscription
and issuance, the “Subscription”).


 


Section 2.Closing.


 


(a) The
consummation of the Subscription contemplated hereby (the “Closing”) shall occur on the Closing Date, following the
SPAC Merger and immediately prior to or substantially concurrently with the consummation of the Acquisition Merger.


 


(b) At
least five (5) Business Days before the anticipated Closing Date, the Company shall (or shall cause Holdings to) deliver written notice
to Subscriber (the “Closing Notice”) specifying (i) the anticipated Closing Date and (ii) the wire instructions for
delivery of the Purchase Price to Holdings. No later than two (2) Business Days prior to the anticipated Closing Date, Subscriber shall
deliver the Purchase Price by wire transfer of United States dollars in immediately available funds to the account specified in the Closing
Notice, such funds to be held in escrow by the Company, Holdings or a third-party escrow provider selected by the Company until the Closing,
and deliver to the Company such information as is reasonably requested in the Closing Notice in order for Holdings to issue the Subscribed
Shares to Subscriber, including, without limitation, the legal name of the person in whose name the Subscribed Shares are to be issued
and a duly completed and executed Internal Revenue Service Form W-9 or appropriate Form W-8. Upon satisfaction (or, if applicable, waiver)
of the conditions set forth in this Section 2, at the Closing (1) the Purchase Price shall be released from escrow automatically
and without further action by Holdings or Subscriber and (2) Holdings shall deliver to Subscriber (A) the Subscribed Shares in book entry
form, free and clear of any liens or other restrictions (other than those arising under applicable securities laws), in the name of Subscriber
(or its nominee or custodian, as applicable, in accordance with its delivery instructions), and (B) as promptly as practicable (but not
more than 24 hours after the Closing), a copy of the records of Holdings’ transfer agent showing Subscriber (or such nominee or
custodian, as applicable) as the owner of the Subscribed Shares on and as of the Closing Date. Notwithstanding the foregoing two sentences,
for any Subscriber that informs the Company and Holdings, (1) that it is an investment
company registered under the Investment Company Act of 1940, as amended, (2) that it is advised by an investment adviser subject to regulation
under the Investment Advisers Act of 1940, as amended, or (3) that its internal compliance policies and procedures so require it, then,
in lieu of the settlement procedures in the foregoing two sentences, the following shall apply: such Subscriber shall deliver on the Closing
Date, and following the consummation of the SPAC Merger, the Purchase Price by wire transfer of United States dollars in immediately available
funds to the account(s) specified by Holdings in the Closing Notice (which account shall not be an escrow account) against delivery of
the Subscribed Shares in book entry form, free and clear of any liens or other restrictions (other than those arising under applicable
securities laws), in the name of the Subscriber (or its nominee in accordance with its delivery instructions) and provide evidence from
Holdings’ transfer agent of the issuance of the Subscribed Shares on and as of the Closing Date (it being understood that such evidence
must be received prior to the Subscriber funding the Purchase Price on the Closing Date). In the event that the consummation of the Transactions
does not occur within two (2) Business Days after the anticipated Closing Date specified in the Closing Notice (the “Closing
Outside Date”), unless otherwise agreed to in writing by the Company and Subscriber, the Company or Holdings, as applicable,
shall promptly (but in no event later than two (2) Business Days after the Closing Outside Date) cause the return of the funds so delivered
by Subscriber by wire transfer in immediately available funds to the account specified by Subscriber, and any book entries shall be deemed
cancelled. Notwithstanding such return or cancellation, (x) a failure to close on the anticipated Closing Date shall not, by itself, be
deemed to be a failure of any of the conditions to Closing set forth in this Section 2 to be satisfied or waived on or prior to
the Closing Date, and (y) unless and until this Subscription Agreement is terminated in accordance with Section 6 herein, Subscriber
shall remain obligated (A) to redeliver funds following the Company’s delivery to Subscriber of a new Closing Notice in accordance
with the terms thereof and (B) to consummate the Closing upon satisfaction of the conditions set forth in this Section 2. For the
purposes of this Subscription Agreement, “Business Day” means any day other than a Saturday, Sunday or any other day
on which commercial banks are required or authorized by law to close in New York, New York; provided that banks shall not be deemed to
be authorized or obligated to be closed due to a “shelter-in-place,” “non-essential employee” or similar closure
of physical branch locations at the direction of any governmental authority if such banks’ electronic funds transfer systems (including
for wire transfers) are open for use by customers on such day.

Closing shall be subject to the satisfaction, or waiver in writing by each of the parties hereto, of the conditions that, on the Closing
Date:


 


		(i)	no suspension of the qualification of the offering or sale or trading of the Class A Common Shares shall
have been initiated or, to the Company’s knowledge, threatened by the U.S. Securities and Exchange Commission (the “SEC”

Stock Exchange (“NYSE”) or Nasdaq, subject to official notice of issuance;



 


		(ii)	all conditions precedent to the closing of the Transactions set forth in the Transaction Agreement shall

nature, are to be satisfied at the closing of the Transactions pursuant to the Transaction Agreement or by the Closing itself, but subject
to their satisfaction or valid waiver at the closing of the Transactions), and following the consummation of the SPAC Merger, the closing
of the additional Transactions shall occur substantially concurrently with or immediately following the Closing; and



 


		(iii)	no court or applicable governmental authority shall have enacted, issued, promulgated, enforced or entered
any judgment, order, law, rule or regulation (whether temporary, preliminary or permanent) which is then in effect and has the effect
of making the consummation of the transactions contemplated hereby illegal or otherwise restraining or prohibiting consummation of the
transactions contemplated hereby and no such court or governmental authority shall have instituted or threatened in writing a proceeding
seeking to impose any such restraint or prohibition.



 


(d) In
addition to the conditions set forth in Section 2(c), the obligation of the Company to consummate the Closing shall be subject
to the satisfaction or waiver by the Company of the additional conditions that, on the Closing Date:

Adverse Effect (as defined below), which representations and warranties shall be true and correct in all respects) at and as of the Closing
Date; and



 


		(ii)	Subscriber shall have performed, satisfied or complied in all material respects with all covenants and
agreements required by this Subscription Agreement to be performed, satisfied or complied with by it at or prior to the Closing.

Date (unless they specifically speak as of an earlier date, in which case they shall be true and correct in all material respects (other
than representations and warranties that are qualified as to Company Material Adverse Effect, which representations and warranties shall
be true and correct in all respects) as of such date);



 


		(ii)	the Company shall have performed, satisfied or complied in all material respects with all covenants and
agreements required by this Subscription Agreement to be performed, satisfied or complied with by it at or prior to the Closing;



 


		(iii)	the Transaction Agreement (as it exists on the date of this Subscription Agreement) shall not have been
amended, modified or waived by the Company in a manner that would reasonably be expected to materially adversely affect the economic benefits

Section 3.Company
Representations and Warranties. The Company represents and warrants to Subscriber and the Placement Agent (as defined below), as
of the date of this Subscription Agreement and as of the Closing, that:


 


(a) The
Company (i) is duly organized, validly existing and in good standing under the laws of its jurisdiction of incorporation, (ii) has the
requisite power and authority to own, lease and operate its properties, to carry on its business as it is now being conducted and to enter
into, deliver and perform its obligations under this Subscription Agreement, and (iii) is duly licensed or qualified to conduct its business
and, if applicable, is in good standing under the laws of each jurisdiction (other than its jurisdiction of incorporation) in which the
conduct of its business or the ownership of its properties or assets requires such license or qualification, except, with respect to the
foregoing clause (iii), where the failure to be in good standing would not reasonably be expected to have a Company Material Adverse
Effect. For purposes of this Subscription Agreement, a “Company Material Adverse Effect” means an event, change, development,
occurrence, condition or effect which (1) would have, individually or in the aggregate, a material adverse effect on the business, financial
condition, stockholders’ equity or results of operations of the Company and its subsidiaries, taken as a whole (after giving effect
to the transactions hereunder and under the Transaction Agreement), or (2) materially affects the validity of the Subscribed Shares or
prevents or materially impairs the ability of the Company to timely perform its obligations under this Subscription Agreement or the Transaction
Agreement, including the issuance and sale of the Subscribed Shares.


 


(b) As
of the Closing Date, the Subscribed Shares will be duly authorized and, when issued and delivered to Subscriber against full payment therefor
in accordance with the terms of this Subscription Agreement, will be validly issued, fully paid and non-assessable, free and clear of
any liens or other restrictions (other than those arising under applicable securities laws), and will not have been issued in violation
of any preemptive or similar rights created under the Company’s organizational documents (as adopted on or prior to the Closing
Date), by any contract to which the Company is a party or by which it is bound, or the laws of the State of Delaware.


 


(c) This
Subscription Agreement, the Other Subscription Agreements, the Note Subscription Agreements and the Transaction Agreement (collectively,
the “Transaction Documents”) have been duly authorized, executed and delivered by the Company, and assuming the due
authorization, execution and delivery of the same by the respective counterparties, the Transaction Documents constitute the valid and
legally binding obligation of the Company, enforceable against the Company in accordance with its terms, except as such enforceability
may be limited by bankruptcy, insolvency, reorganization, moratorium and similar laws affecting creditors generally and by the availability
of equitable remedies.


 




    	 	4	 



     


    

 


(d) The
execution, delivery and performance of the Transaction Documents, the issuance and sale of the Subscribed Shares and the Convertible Notes,
and the compliance by the Company with all of the provisions of the Transaction Documents and the consummation of the transactions contemplated
in any of them will not conflict with or result in a breach or violation of any of the terms or provisions of, or constitute a default
under, or result in the creation or imposition of any lien, charge or encumbrance upon any of the property or assets of the Company pursuant
to the terms of (i) any indenture, mortgage, deed of trust, loan agreement, lease, license or other agreement or instrument to which the
Company is a party or by which the Company is bound or to which any of the property or assets of the Company is subject, in each case,
that would reasonably be expected to have a Company Material Adverse Effect; (ii) the organizational documents of the Company; or (iii)
any statute or any judgment, order, rule or regulation of any court or governmental agency or body having jurisdiction over the Company,
or any of its properties that would reasonably be expected to have a Company Material Adverse Effect.


 


(e) Assuming
the accuracy of the representations and warranties of Subscriber set forth in Section 4 of this Subscription Agreement, the
Company is not required to obtain any consent, waiver, authorization or order of, give any notice to, or make any filing or
registration with, any court or other federal, state, local or other governmental authority, self-regulatory organization (including
NYSE or Nasdaq, as applicable) or other person in connection with the execution, delivery and performance of this Subscription
Agreement (including, without limitation, the issuance of the Subscribed Shares), other than (i) filings required by applicable
state securities laws, (ii) the filing of the Registration Statement pursuant to Section 5 below, (iii) those required by the
SEC or the NYSE or Nasdaq, as applicable, including with respect to obtaining stockholder approval, (iv) those required to consummate
the Transactions as provided under the Transaction Agreement, (v) the filing of notification under the Hart-Scott-Rodino Antitrust
Improvements Act of 1976, if applicable, and (vi) any consent, waiver, authorization, order, notice, filing or registration the
failure of which to make or obtain would not reasonably be expected to have a Company Material Adverse Effect.


 


(f) Assuming
the accuracy of Subscriber’s representations and warranties set forth in Section 4 of this Subscription Agreement, no registration
under the Securities Act of 1933, as amended (the “Securities Act”), is required for the offer and sale of the Subscribed
Shares to Subscriber and the Subscribed Shares are not being offered in a manner involving a public offering under, or in a distribution
in violation of, the Securities Act or any state securities laws. The Subscribed Shares are not being offered in a manner involving a
public offering under, or in a distribution in violation of, the Securities Act or any state securities laws.


 


(g) The
Subscribed Shares are not, and following the consummation of the Transactions and the Closing hereunder will not be, subject to any Transfer
Restriction. The term “Transfer Restriction” means any condition to or restriction on the ability of the Subscriber to pledge,
sell, assign or otherwise transfer the Subscribed Shares under any organizational document, policy or agreement of, by or with the Company,
but excluding the restrictions on transfer described in paragraph 4(e) of this Subscription Agreement with respect to the status of the
Subscribed Shares as “restricted securities”.


 


(h) Neither
the Company nor any person acting on its behalf has engaged or will engage in any form of general solicitation or general advertising
(within the meaning of Regulation D) in connection with any offer or sale of the Subscribed Shares.


 




    	 	5	 



     


    

 


(i) The
Company has not entered into any agreement or arrangement entitling any agent, broker, investment banker, financial advisor or other person
to any broker’s or finder’s fee or any other commission or similar fee in connection with the transactions contemplated by
this Subscription Agreement for which Subscriber could become liable. Except for Goldman Sachs & Co. LLC (“Goldman Sachs”
or, the “Placement Agent”), no broker or finder is entitled to any brokerage or finder’s fee or commission solely
in connection with the sale of the Subscribed Shares to Subscriber.


 


(j) As
of their respective dates, all forms, reports, statements, schedules, prospectuses, proxies, registration statements and other documents
required to be filed by the Company with the SEC (the “SEC Reports”) complied in all material respects with the applicable
requirements of the Securities Act and the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and the
rules and regulations of the SEC promulgated thereunder, and none of the SEC Reports, when filed, contained any untrue statement of a
material fact or omitted to state a material fact required to be stated therein or necessary in order to make the statements therein,
in the light of the circumstances under which they were made, not misleading; provided, that notwithstanding anything to the contrary
in this Section 3(j), no representation or warranty is made under this Section 3(j) as to the accounting treatment of the
Company’s issued and outstanding warrants, or as to any deficiencies in disclosure (including with respect to accounting and disclosure
controls) arising from the accounting treatment of such warrants as equity rather than liabilities in the Company’s financial statements.
The financial statements of the Company included in the SEC Reports were prepared in accordance with generally accepted accounting principles
in the United States, consistently applied, comply in all material respects with the rules and regulations of the SEC with respect thereto
as in effect at the time of filing and fairly present in all material respects the financial position of the Company, as of and for the
dates thereof and the results of operations and cash flows for the periods then ended, subject, in the case of unaudited statements, to
normal, year-end audit adjustments and the absence of certain footnotes and other presentation items. Except as disclosed in the SEC Reports,
the Company timely filed each report, statement, schedule, prospectus, and registration statement that the Company was required to file
with the SEC since inception. A copy of each SEC Report is available to Subscriber via the SEC’s EDGAR system. There are no outstanding
or unresolved comments in comment letters received by the Company from the staff of the Division of Corporation Finance of the SEC with
respect to any of the SEC Reports.


 


(k) As
of the date hereof, the issued and outstanding Class A Common Shares are registered pursuant to Section 12(b) of the Exchange Act, and
listed for trading on the NYSE under the symbol “FMAC.” There is no suit, action, proceeding or investigation pending or,
to the knowledge of the Company, threatened against the Company by the NYSE or the SEC, respectively, to prohibit or terminate the listing
of the Class A Common Shares on the NYSE or to deregister such shares under the Exchange Act, excluding, for purposes of clarity, the
customary ongoing review by the NYSE of the Company’s continued listing application in connection with the Transactions. The Company
has not taken any action that is designed to terminate the registration of the Class A Common Shares under the Exchange Act or the listing
of the Class A Common Shares on the NYSE, and is in compliance in all material respects with the continued listing requirement of the
NYSE, except the Company may delist Class A Common Shares from NYSE in connection with submitting a listing application to Nasdaq, in accordance
with Nasdaq rules, covering the shares of Class A Common Shares.

(l) Other
than the Other Subscription Agreements, the Note Subscription Agreements, the Transaction Agreement and any other agreement contemplated
by the Transaction Agreement, the Company has not entered into any side letter or similar agreement or understanding with any Other Subscriber
or any affiliate thereof or any other investor in connection with such Other Subscriber’s (considered with any such affiliate) or
investor’s direct or indirect investment in the Company (other than any side letter or similar agreement relating to the transfer
to any investor of (i) securities of the Company by existing securityholders of the Company, which may be effectuated as a forfeiture
to the Company and reissuance, or (ii) securities to be issued to the direct or indirect securityholders of the Company pursuant to the
Transaction Agreement). Each Other Subscription Agreement reflects the same Per Share Price as this Subscription Agreement, and no Other
Subscription Agreement includes terms and conditions (economic or otherwise) that are more advantageous in any material respect to any
such Other Subscriber than Subscriber hereunder, other than terms particular to the regulatory requirements of such Other Subscriber or
its affiliates or related funds that are mutual funds or are otherwise subject to regulations related to the timing of funding and the
issuance of the related Class A Common Shares. The Other Subscription Agreements have not been and will not, without the prior written
consent of the Subscriber, be amended or modified in any material respect following the date of this Subscription Agreement. The Company
and its affiliates shall not release any Other Subscriber (or any of its affiliates) under any Other Subscription Agreement from any of
its material obligations thereunder or any other agreements (including side letters or similar agreements or understandings in respect
thereof) with any Other Subscriber (or any of its affiliates) under any Other Subscription Agreement unless it offers a similar release
to the Subscriber with respect to any similar obligations it has hereunder.


 


(m) Except
for such matters as have not had or would not reasonably be expected to have, individually or in the aggregate, a Company Material Adverse
Effect, there is no (i) action, suit, claim or other proceeding, in each case by or before any governmental authority pending, or, to
the knowledge of the Company, threatened against the Company or (ii) judgment, decree, injunction, ruling or order of any governmental
entity or arbitrator outstanding against the Company.


 


(n) The
Company is in compliance with all applicable laws, except where such noncompliance would not reasonably be expected to have, individually
or in the aggregate, a Company Material Adverse Effect. The Company has not received any written communication from a governmental entity
alleging that it is not in compliance with or is in default or violation of any applicable law, except where such noncompliance, default
or violation would not, individually or in the aggregate, reasonably be expected to have a Company Material Adverse Effect.


 


(o) (i)
The Company, and, to the knowledge of the Company, the officers, directors, employees, and agents of the Company, in each case, acting
on behalf of the Company, have been in compliance in all material respects with all applicable Anti-Corruption Laws (as herein defined),
(ii) the Company has not been convicted of violating any Anti-Corruption Laws or, to the knowledge of the Company, subjected to any investigation
by a governmental authority for violation of any applicable Anti-Corruption Laws, (iii) the Company has not conducted or initiated any
internal investigation or made a voluntary, directed, or involuntary disclosure to any governmental authority regarding any alleged act
or omission arising under or relating to any noncompliance with any Anti-Corruption Laws and (iv) the Company has not received any written
notice or citation from a governmental authority for any actual or potential noncompliance with any applicable Anti-Corruption Laws. As
used herein, “Anti-Corruption Laws” means any applicable laws relating to corruption and bribery, including the U.S. Foreign
Corrupt Practices Act of 1977 (as amended), the UK Bribery Act 2010, and any similar law that prohibits bribery or corruption.

stock, par value $0.0001 per share (the “Company Preferred Stock”) and (ii) 520,000,000 shares of common stock, including
(1) 500,000,000 shares of Class A Common Shares, and (2) 20,000,000 shares of Class B common stock, par value $0.0001 per share (the “Class

fully paid and are non-assessable and are not subject to preemptive rights and (ii) outstanding warrants of the Company have been duly
authorized and validly issued, are fully paid and are not subject to preemptive rights. Upon consummation of the Transactions, the authorized

Except as set forth above and pursuant to the Other Subscription Agreements, the Note Subscription Agreements, the Transaction Agreement
and the other agreements and arrangements referred to in the Transaction Agreement, as of the date hereof, there are no outstanding options,
warrants or other rights to subscribe for, purchase or acquire from the Company any Class A Common Shares, Class A Common Shares or other
equity interests in the Company, or securities convertible into or exchangeable or exercisable for such equity interests. As of the date
hereof, the Company has no subsidiaries and does not own, directly or indirectly, interests or investments (whether equity or debt) in
any person, whether incorporated or unincorporated. There are no stockholder agreements, voting trusts or other agreements or understandings
to which the Company is a party or by which it is bound relating to the voting of any securities of the Company, as applicable, other
than (A) as set forth in the SEC Reports and (B) as contemplated by the Transaction Agreement. There are no securities or instruments
issued by or to which the Company is a party containing anti-dilution or similar provisions that will be triggered by the issuance of
(i) the Subscribed Shares or (ii) the Class A Common Shares to be issued pursuant to the Other Subscription Agreements or upon conversion
of the Convertible Notes, that have not been or will not be validly waived on or prior to the Closing Date, including such provisions
in the shares of Class B Common Shares pursuant to the terms of the Company’s organizational documents (as amended as of the Closing
Date).


 


Section 4.Subscriber
Representations and Warranties. Subscriber represents and warrants to the Company and the Placement Agent that:


 


(a) Subscriber
(i) is duly organized, validly existing and in good standing under the laws of its jurisdiction of incorporation or formation, and (ii)
has the requisite power and authority to enter into and perform its obligations under this Subscription Agreement.


 




    	 	8	 



     


    

  


(b) This
Subscription Agreement has been duly executed and delivered by Subscriber, and assuming the due authorization, execution and delivery
of the same by the Company, this Subscription Agreement constitutes the valid and legally binding obligation of Subscriber, enforceable
against Subscriber in accordance with its terms, except as such enforceability may be limited by bankruptcy, insolvency, reorganization,
moratorium and similar laws affecting creditors generally and by the availability of equitable remedies.


 


(c) The
execution and delivery of this Subscription Agreement, the purchase of the Subscribed Shares and the compliance by Subscriber with all
of the provisions of this Subscription Agreement and the consummation of the transactions contemplated herein will not conflict with or
result in a breach or violation of any of the terms or provisions of, or constitute a default under, or result in the creation or imposition
of any lien, charge or encumbrance upon any of the property or assets of Subscriber pursuant to the terms of (i) any indenture, mortgage,
deed of trust, loan agreement, lease, license or other agreement or instrument to which Subscriber is a party or by which Subscriber is
bound or to which any of the property or assets of Subscriber is subject; (ii) the organizational documents of Subscriber; or (iii) any
statute or any judgment, order, rule or regulation of any court or governmental agency or body, domestic or foreign, having jurisdiction
over Subscriber or any of its properties that, in the case of clauses (i) and (iii), would reasonably be expected to have
a Subscriber Material Adverse Effect. For purposes of this Subscription Agreement, a “Subscriber Material Adverse Effect”
means an event, change, development, occurrence, condition or effect with respect to Subscriber that would reasonably be expected to have
a material adverse effect on Subscriber’s ability to consummate the transactions contemplated hereby, including the purchase of
the Subscribed Shares.


 


(d) Subscriber
(i) is a “qualified institutional buyer” (as defined in Rule 144A under the Securities Act) or an institutional “accredited
investor” (within the meaning of Rule 501(a)(1), (2), (3) or (7) under the Securities Act), in each case, satisfying the applicable
requirements set forth on Annex A, (ii) is acquiring the Subscribed Shares only for its own account and not for the account of
others, or if Subscriber is subscribing for the Subscribed Shares as a fiduciary or agent for one or more investor accounts, each owner
of such account is a qualified institutional buyer or institutional accredited investor (as the case may be) and Subscriber has full investment
discretion with respect to each such account, and the full power and authority to make the acknowledgements, representations and agreements
herein on behalf of each owner of each such account, and (iii) is not acquiring the Subscribed Shares with a view to, or for offer or
sale in connection with, any distribution thereof in violation of the Securities Act (and shall provide the requested information on Annex
A). Subscriber is not an entity formed for the specific purpose of acquiring the Subscribed Shares, unless such newly formed entity
is an entity in which all of the investors are institutional accredited investors, and is an “institutional account” as defined
by FINRA Rule 4512(c). Subscriber is a sophisticated institutional investor, experienced in investing in private equity transactions and
capable of evaluating investment risks independently, both in general and with regard to all transactions and investment strategies involving
a security or securities. Accordingly, Subscriber understands that the purchase of the Subscribed Shares meets (i) the exemptions from
filing under FINRA Rule 5123(b)(1)(A) and (ii) the institutional customer exemption under FINRA Rule 2111(b).

(e) Subscriber
understands that the Subscribed Shares are being offered in a transaction not involving any public offering within the meaning of the
Securities Act and that the Subscribed Shares have not been registered under the Securities Act. Subscriber understands that the Subscribed
Shares may not be offered, resold, transferred, pledged or otherwise disposed of by Subscriber absent an effective registration statement
under the Securities Act, except (i) to the Company or a subsidiary thereof, or (ii) pursuant to an applicable exemption from the registration
requirements of the Securities Act, and, in each of cases (i) and (ii), in accordance with any applicable securities laws of the states
and other jurisdictions of the United States, and as a result of these transfer restrictions, Subscriber may not be able to readily resell
the Subscribed Shares and may be required to bear the financial risk of an investment in the Subscribed Shares for an indefinite period
of time. Subscriber acknowledges and agrees that the Subscribed Shares will not be eligible for offer, resale, transfer, pledge or disposition
pursuant to Rule 144 promulgated under the Securities Act (“Rule 144”) until at least one year from the filing of “Form
10 information” with the Commission after the Closing Date. Subscriber understands that it has been advised to consult legal counsel
prior to making any offer, resale, pledge or transfer of any of the Subscribed Shares.


 


(f) Subscriber
understands and agrees that Subscriber is purchasing the Subscribed Shares directly from the Company. Subscriber further acknowledges
that there have not been, and Subscriber hereby agrees that it is not relying on, any representations, warranties, covenants or agreements
made to Subscriber by the Company, the Placement Agent, any of their respective affiliates or any control persons, officers, directors,
employees, partners, agents or representatives, any other party to the Transactions or any other person or entity, expressly or by implication,
other than those representations, warranties, covenants and agreements of the Company expressly set forth in this Subscription Agreement,
and Subscriber hereby represents and warrants that it is relying exclusively on Subscriber’s own sources of information, investment
analysis and due diligence (including professional advice such Subscriber deems appropriate) with respect to this offering of the Subscribed
Shares, and the business, condition (financial and otherwise), management, operations, properties and prospects of the Company and Target,
including but not limited to all business, legal, regulatory, accounting, credit and tax matters. Subscriber acknowledges that certain
information provided to Subscriber was based on projections, and such projections were prepared based on assumptions and estimates that
are inherently uncertain and are subject to a wide variety of significant business, economic and competitive risks and uncertainties that
could cause actual results to differ materially from those contained in the projections. Subscriber acknowledges that it has been informed
that no disclosure or offering document has been prepared by the Placement Agent or any of its affiliates in connection with the offer
and sale of the Subscribed Shares. In connection with the issuance and sale of the Subscribed Shares, the Placement Agent has not acted
as a financial advisor or fiduciary to the Subscriber. Neither the Placement Agent nor any of its directors, officers, employees, representatives
or controlling persons has made any independent investigation with respect to the Company, the Subscribed Shares or the completeness or
accuracy of any information provided to Subscriber. Subscriber agrees that neither the Placement Agent, nor any of its affiliates or any
of its or its affiliates’ control persons, officers, directors or employees, shall be liable to Subscriber pursuant to this Subscription
Agreement for any action heretofore or hereafter taken or omitted to be taken by any of them in connection with the purchase of the Subscribed
Shares.


 


(g) In
making its decision to purchase the Subscribed Shares, Subscriber has relied solely upon independent investigation made by Subscriber
and the Company’s representations and warranties in Section 3. Subscriber acknowledges and agrees that Subscriber has received
such information as Subscriber deems necessary in order to make an investment decision with respect to the Subscribed Shares, including
with respect to the Company and its subsidiaries and the Transactions. Subscriber represents and agrees that Subscriber and Subscriber’s
professional advisor(s), if any, have had the full opportunity to ask such questions, receive such answers and obtain such information
as Subscriber and its professional advisor(s), if any, have deemed necessary to make an investment decision with respect to the Subscribed
Shares. Subscriber acknowledges and agrees that neither the Placement Agent, nor any affiliate of the Placement Agent, has provided Subscriber
with any information or advice with respect to the Subscribed Shares nor is such information or advice necessary or desired. Neither the
Placement Agent nor any of its affiliates has made or makes any representation as to the Company or the quality or value of the Subscribed
Shares, and the Placement Agent and any of its affiliates may have acquired nonpublic information with respect to the Company which Subscriber
agrees, subject to applicable law, need not be provided to it.


 


(h) Subscriber
is able to fend for itself in the transactions contemplated herein, has such knowledge and experience in financial and business matters
as to be capable of evaluating the merits and risks of our prospective investment in the Subscribed Shares and has the ability to bear
the economic risks of its prospective investment and can afford the complete loss of such investment.


 


(i) Subscriber
became aware of this offering of the Subscribed Shares solely by means of direct contact between Subscriber and the Company, the Target
or their respective representatives or affiliates, or by means of contact from the Placement Agent, and the Subscribed Shares were offered
to Subscriber solely by direct contact between Subscriber and the Company, or their respective representatives or affiliates. Subscriber
did not become aware of this offering of the Subscribed Shares, nor were the Subscribed Shares offered to Subscriber, by any other means.
Subscriber acknowledges that the Company represents and warrants that the Subscribed Shares (i) were not offered by any form of general
solicitation or general advertising and (ii) are not being offered in a manner involving a public offering under, or in a distribution
in violation of, the Securities Act, or any state securities laws.


 


(j) Subscriber
acknowledges that it is aware that there are substantial risks incident to the purchase and ownership of the Subscribed Shares. Subscriber
has such knowledge and experience in financial and business matters as to be capable of evaluating the merits and risks of an investment
in the Subscribed Shares, and Subscriber has had an opportunity to seek, and has sought, such accounting, legal, business and tax advice
as Subscriber has considered necessary to make an informed investment decision. Subscriber acknowledges and agrees that none of the Company
or any of its affiliates has provided any tax advice to Subscriber or made any representations or warranties or guarantees to Subscriber
regarding the tax treatment of its investment in the Subscribed Shares.


 




    	 	10	 



     


    

  


(k) Subscriber
has analyzed and considered the risks of an investment in the Subscribed Shares and determined that the Subscribed Shares are a suitable
investment for Subscriber and that Subscriber is able at this time and in the foreseeable future to bear the economic risk of a total
loss of Subscriber’s investment in the Company. Subscriber acknowledges specifically that a possibility of total loss exists.


 


(l) Subscriber
understands and agrees that no federal or state agency has passed upon or endorsed the merits of the offering of the Subscribed Shares
or made any findings or determination as to the fairness of this investment.


 


(m) Subscriber
is not, and is not owned or controlled by or acting on behalf of (in connection with the Transactions), a Sanctioned Person. Subscriber
is not a non-U.S. shell bank or providing banking services to a non-U.S. shell bank. Subscriber represents that if it is a financial institution
subject to the Bank Secrecy Act (31 U.S.C. Section 5311 et seq.), as amended by the USA PATRIOT Act of 2001 and its implementing regulations
(collectively, the “BSA/PATRIOT Act”), Subscriber maintains policies and procedures reasonably designed to comply with
applicable obligations under the BSA/PATRIOT Act. Subscriber also represents that it maintains, to the extent required, either directly
or through the use of a third-party administrator, policies and procedures reasonably designed for the screening of any investors against
Sanctions-related lists of blocked or restricted persons and to ensure that the funds held by Subscriber and used to purchase the Subscribed
Shares are derived from lawful activities. For purposes of this Subscription Agreement, “Sanctioned Person” means at
any time any person or entity: (i) listed on any Sanctions-related list of designated or blocked or restricted persons; (ii) that
is a national of, the government of, or any agency or instrumentality of the government of, or resident in, or organized under the laws
of, a country or territory that is the target of comprehensive Sanctions from time to time (as of the date of this Subscription Agreement,
Cuba, Iran, North Korea, Syria, and the Crimea region); or (iii) owned or controlled by or acting on behalf of any of the foregoing. “Sanctions”
means those trade, economic and financial sanctions laws, regulations, embargoes, and restrictive measures (in each case having the force
of law) administered, enacted or enforced from time to time by (1) the United States (including without limitation the U.S. Department
of the Treasury, Office of Foreign Assets Control, the U.S. Department of State, and the U.S. Department of Commerce), (2) the European
Union and enforced by its member states, (3) the United Nations and (4) Her Majesty’s Treasury.


 


(n) Subscriber
is not currently (and at all times through Closing will refrain from being or becoming) a member of a “group” (within the
meaning of Section 13(d)(3) or Section 14(d)(2) of the Exchange Act or any successor provision) acting for the purpose of acquiring, holding,
voting or disposing of equity securities of the Company (within the meaning of Rule 13d-5(b)(1) under the Exchange Act).


  


(o) If
Subscriber is an employee benefit plan that is subject to Title I of the Employee Retirement Income Security Act of 1974, as amended (“ERISA”),
a plan, an individual retirement account or other arrangement that is subject to section 4975 of the Internal Revenue Code of 1986, as
amended (the “Code”) or an employee benefit plan that is a governmental plan (as defined in section 3(32) of ERISA),
a church plan (as defined in section 3(33) of ERISA), a non-U.S. plan (as described in section 4(b)(4) of ERISA) or other plan that is
not subject to the foregoing but may be subject to provisions under any other federal, state, local, non-U.S. or other laws or regulations
that are similar to such provisions of ERISA or the Code, or an entity whose underlying assets are considered to include “plan assets”
of any such plan, account or arrangement (each, a “Plan”) subject to the fiduciary or prohibited transaction provisions
of ERISA or section 4975 of the Code, Subscriber represents and warrants that (i) it has not relied on the Company or any of its affiliates
(the “Transactions Parties”) as the Plan’s fiduciary or for advice, with respect to its decision to acquire and
hold the Subscribed Shares, and none of the Transactions Parties shall at any time be relied upon as the Plan’s fiduciary with respect
to any decision to acquire, continue to hold or transfer the Subscribed Shares and (ii) none of the acquisition, holding and/or transfer
or disposition of the Subscribed Shares will result in a non-exempt prohibited transaction under ERISA or Section 4975 of the Code or
any similar law or regulation.


 


(p) Subscriber
will have sufficient immediately available funds to pay the Purchase Price pursuant to Section 2.


 


(q) Subscriber
acknowledges and is aware that (i) the Placement Agent is acting as the Company’s placement agent, (ii) the Placement Agent is serving
as financial advisor to Target in connection with the Transactions, and (iii) the Company is an affiliate of FirstMark Capital (“FirstMark
Capital”) and one or more affiliates of FirstMark Capital own approximately 24% of the fully diluted equity of the Company and
approximately 15% of the fully diluted equity of Target. Subscriber understands and acknowledges that (1) Goldman Sachs’s role as
financial advisor to Target may give rise to potential conflicts of interest or the appearance thereof, and (2) the Company’s relationship
with FirstMark Capital or any of FirstMark Capital’s affiliates or affiliated funds may give rise to potential conflicts of interest
or the appearance thereof.

Section 5.Registration
of Subscribed Shares.


 


(a) The
Company agrees that the Company will file with the Commission (at the Company’s sole cost and expense) a registration statement
registering the resale of the Subscribed Shares (the “Registration Statement”) no later than fifteen (15) Business
Days after the Closing Date, and the Company shall use its commercially reasonable efforts to have the Registration Statement declared
effective as soon as practicable after the filing thereof, but no later than the earlier of (i) sixty (60) calendar days after the filing
thereof (or, in the event the Commission reviews and has written comments to the Registration Statement, the ninetieth (90th) calendar
day following the filing thereof) and (ii) the tenth (10th) Business Day after the date the Company is notified (orally or in writing,
whichever is earlier) by the Commission that the Registration Statement will not be “reviewed” or will not be subject to further
review ((i) and (ii) collectively, the “Effectiveness Deadline”); provided, that if such day falls on a Saturday,
Sunday or other day that the Commission is closed for business, the Effectiveness Deadline shall be extended to the next Business Day
on which the Commission is open for business. The Company will use its commercially reasonable efforts to provide a draft of the Registration
Statement to Subscriber for review at least two (2) Business Days in advance of filing the Registration Statement; provided that,
for the avoidance of doubt, in no event shall the Company be required to delay or postpone the filing of such Registration Statement as
a result of or in connection with Subscriber’s review. Unless otherwise agreed to in writing by Subscriber, Subscriber shall not
be identified as a statutory underwriter in the Registration Statement unless requested by the Commission or another regulatory agency;
provided, that if the Commission or another regulatory agency requests that a Subscriber be identified as a statutory underwriter
in the Registration Statement, Subscriber will have the opportunity to withdraw from the Registration Statement upon its prompt written
request to the Company. Notwithstanding the foregoing, if the Commission prevents the Company from including any or all of the shares
proposed to be registered under the Registration Statement due to limitations on the use of Rule 415 of the Securities Act for the resale
of the Subscribed Shares by the applicable stockholders or otherwise, such Registration Statement shall register for resale such number
of Subscribed Shares which is equal to the maximum number of Subscribed Shares as is permitted by the Commission. In such event, the number
of Subscribed Shares to be registered for each selling stockholder named in the Registration Statement shall be reduced pro rata among
all such selling stockholders and as promptly as practicable after being permitted to register additional Subscribed Shares under Rule
415 under the Securities Act, the Company shall amend the Registration Statement or file a new Registration Statement to register such
Subscribed Shares not included in the Registration Statement and cause such amendment or Registration Statement to become effective as
promptly as practicable. The Company agrees that, except for such times as the Company is permitted hereunder to suspend the use of the
prospectus forming part of a Registration Statement, at its expense, the Company will use its commercially reasonable efforts to cause
such Registration Statement to remain effective with respect to Subscriber, and to keep the applicable Registration Statement supplemented
and amended to the extent necessary to ensure that such Registration Statement is available or, if not available, that another registration
statement is available for the resale of the Subscribed Shares and ensure that the applicable Registration Statement or any subsequent
shelf registration statement is free of any material misstatements or omissions, until the earlier of (i) three (3) years from the issuance
of the Subscribed Shares, (ii) the date on which all of the Subscribed Shares shall have been sold, or (iii) the first date on which Subscriber
can sell all of its Subscribed Shares (or shares received in exchange therefor) under Rule 144 without limitation, including as to the
manner of sale or the amount of such securities that may be sold and without the requirement for the Company to be in compliance with
the current public information required under Rule 144(c)(1) (or Rule 144(i)(2), if applicable). Subject to receipt from the Subscriber
by the Company and the Company’s transfer agent of customary representations and other documentation reasonably acceptable to the
Company in connection therewith, the Subscriber may request that the Company remove any legend from the book entry position evidencing
its Subscribed Shares and the Company will, if required by the Company’s transfer agent, use its commercially reasonable efforts
cause an opinion of the Company’s counsel be provided, in a form reasonably acceptable to the Company’s transfer agent to
the effect that the removal of such restrictive legends in such circumstances may be effected under the Securities Act, following the
earliest of such time as the Subscribed Shares (1) are subject to or have been or may be sold or transferred pursuant to an effective
registration statement, (2) have been or may be sold pursuant to Rule 144, or (3) are eligible for resale under Rule 144(b)(1) or any
successor provision without the requirement for the Company to be in compliance with the current public information requirement under
Rule 144 and without volume or manner-of-sale restrictions applicable to the sale or transfer of such Subscribed Shares, or another exemption
from registration. If restrictive legends are no longer required for the Subscribed Shares pursuant to the foregoing, the Company shall,
in accordance with the provisions of this section and within five (5) trading days of any request therefor from the Subscriber accompanied
by such customary and reasonably acceptable representations and other documentation referred to above establishing that restrictive legends
are no longer required, deliver to the Company’s transfer agent irrevocable instructions to make a new, unlegended entry in book-entry
form or by electronic delivery through The Depository Trust Company for such Subscribed Shares. The Company shall be responsible for the
fees of its transfer agent, its legal counsel and all DTC fees associated with such issuance. From and after such time as the benefits
of Rule 144 or any other similar rule or regulation of the Commission that may allow Subscriber to sell securities of the Company to the
public without registration are available to holders of the Company’s common stock, the Company shall, at its expense, make and
keep public information available, as those terms are understood and defined in Rule 144; use commercially reasonable efforts to file
with the Commission in a timely manner all reports and other documents required of the Company under the Securities Act and the Exchange
Act so long as the Company remains subject to such requirements and the filing of such reports and other documents is required for the
applicable provisions of Rule 144 to enable Subscriber to sell the Subscribed Shares under Rule 144 for so long as Subscriber holds any
Subscribed Shares; and furnish to Subscriber, promptly upon Subscriber’s reasonable request, (i) a written statement by the Company,
if true, that it has complied with the reporting requirements of Rule 144, the Securities Act, and the Exchange Act, (ii) a copy of the
most recent annual or quarterly report of the Company and such other reports and documents so filed by the Company, and (iii) such other
information as may be reasonably requested to permit Subscriber to sell such securities pursuant to Rule 144 without registration. “Subscribed
Shares” shall be deemed to include, as of any date of determination, any equity security issued or issuable with respect to the
Subscribed Shares by way of share split, dividend, distribution, recapitalization, merger, exchange, replacement or similar event. “Holder”
shall mean Subscriber or any affiliate of Subscriber or other person to whom the rights under this Section 5 shall have been assigned.
The Company’s obligations to include the Subscribed Shares in the Registration Statement are contingent upon Subscriber furnishing
in writing to the Company such information regarding Subscriber, the securities of the Company held by Subscriber and the intended method
of disposition of the Subscribed Shares as shall be reasonably requested by the Company to effect the registration of the Subscribed Shares,
and Subscriber shall execute such documents in connection with such registration as the Company may reasonably request that are customary
of a selling stockholder in similar situations, including providing that the Company shall be entitled to postpone and suspend the effectiveness
or use of the Registration Statement as permitted hereunder; provided, however, that Subscriber shall not in connection
with the foregoing be required to execute any lock-up or similar agreement or otherwise be subject to any contractual restriction on the
ability to transfer the Subscribed Shares. In the case of the registration effected by the Company pursuant to this Subscription Agreement,
the Company shall, upon reasonable request, inform Subscriber as to the status of such registration. Subscriber shall not be entitled
to use the Registration Statement for an underwritten offering of Subscribed Shares. Notwithstanding anything to the contrary contained
herein, the Company may delay or postpone filing of such Registration Statement, and from time to time require Subscriber not to sell
under the Registration Statement or suspend the use or effectiveness of any such Registration Statement if it determines that, in order
for the registration statement to not contain a material misstatement or omission, an amendment thereto would be needed, or if the negotiation
or consummation of a transaction by the Company or its subsidiaries is pending or an event has occurred, which negotiation, consummation
or event the Company’s board of directors reasonably believes, upon the advice of outside legal counsel, would require additional
disclosure by the Company in the Registration Statement of material information that the Company has a bona fide business purpose for
keeping confidential and the non-disclosure of which in the Registration Statement would be expected, in the reasonable determination
of the Company’s board of directors, upon the advice of outside legal counsel, to cause the Registration Statement to fail to comply
with applicable disclosure requirements, or if the Commission issues any stop order suspending the effectiveness of any Registration Statement
or indicates the intention to initiate any proceedings for such purpose (each such circumstance, a “Suspension Event”);
provided, that, (x) the Company shall not so delay filing or so suspend the use of the Registration Statement for a period of more
than forty five (45) consecutive days or more than two (2) times in any three hundred sixty (360) day period and (y) the Company shall
use commercially reasonable efforts to make such registration statement available for the sale by Subscriber of such securities as soon
as practicable thereafter.


 




    	 	12	 



     


    

 


(b) Upon
receipt of any written notice from the Company (which notice shall not contain any material nonpublic information regarding the Company)
of the occurrence of any Suspension Event during the period that the Registration Statement is effective or if as a result of a Suspension
Event the Registration Statement or related prospectus contains any untrue statement of a material fact or omits to state any material
fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made
(in the case of the prospectus) not misleading, Subscriber agrees that (i) it will immediately discontinue offers and sales of the Subscribed
Shares under the Registration Statement (excluding, for the avoidance of doubt, sales conducted pursuant to Rule 144) until Subscriber
receives copies of a supplemental or amended prospectus (which the Company agrees to promptly prepare) that corrects the misstatement(s)
or omission(s) referred to above and receives notice that any post-effective amendment has become effective or unless otherwise notified
by the Company that it may resume such offers and sales, and (ii) it will maintain the confidentiality of any information included in
such written notice delivered by the Company unless otherwise required by law, subpoena or regulatory request or requirement. If so directed
by the Company, Subscriber will deliver to the Company, or in Subscriber’s sole discretion destroy, all copies of the prospectus
covering the Subscribed Shares in Subscriber’s possession; provided, however, that this obligation to deliver or destroy
all copies of the prospectus covering the Subscribed Shares shall not apply (x) to the extent Subscriber is required to retain a copy
of such prospectus (A) in order to comply with applicable legal, regulatory, self-regulatory or professional requirements or (B) in accordance
with a bona fide pre-existing document retention policy or (y) to copies stored electronically on archival servers as a result of automatic
data back-up.


 


(c) The
Company shall advise Subscriber within two (2) Business Days:


 


		(i)	when a Registration Statement or any amendment thereto has been filed with the Commission, and when such
Registration Statement or any post-effective amendment thereto has become effective;



 


		(ii)	of the issuance by the Commission of any stop order suspending the effectiveness of any Registration Statement
or the initiation of any proceedings for such purpose;



 


		(iii)	of the receipt by the Company of any notification with respect to the suspension of the qualification
of the Subscribed Shares included therein for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose;
and



 


		(iv)	subject to the provisions in this Subscription Agreement, of the occurrence of any event that requires
the making of any changes in any Registration Statement or prospectus so that, as of such date, the statements therein are not misleading
and do not omit to state a material fact required to be stated therein or necessary to make the statements therein (in the case of a prospectus,
in the light of the circumstances under which they were made) not misleading.



 


Notwithstanding anything to
the contrary set forth herein, the Company shall not, when so advising Subscriber of such events, provide Subscriber with any material,
nonpublic information regarding the Company other than to the extent that providing notice to Subscriber of the occurrence of the events
listed in (i) through (iv) above may constitute material, nonpublic information regarding the Company.


 


(d) The
Company shall use its commercially reasonable efforts to obtain the withdrawal of any order suspending the effectiveness of any Registration
Statement as soon as reasonably practicable.


 


(e) Except
for such times as the Company is permitted hereunder to suspend, and has suspended, the use of a prospectus forming part of a Registration
Statement as contemplated by this Subscription Agreement, the Company shall use its commercially reasonable efforts to as soon as reasonably
practicable prepare a post-effective amendment to such Registration Statement or a supplement to the related prospectus, or file any other
required document so that, as thereafter delivered to purchasers of the Subscribed Shares included therein, such prospectus will not include
any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in the light of the
circumstances under which they were made, not misleading.


 


(f) The
Company shall use its commercially reasonable efforts to cause all Subscribed Shares to be listed on each securities exchange or market,
if any, on which the Company’s common stock has been listed.


 


(g) The
Company shall use its commercially reasonable efforts to take all other steps necessary to effect the registration of the Subscribed Shares
required hereby.

Section 6.Termination.
This Subscription Agreement shall terminate and be void and of no further force and effect, and all rights and obligations of the parties
hereunder shall terminate without any further liability on the part of any party in respect thereof, upon the earliest to occur of (a)
such date and time as the Transaction Agreement is terminated in accordance with its terms without being consummated, (b) upon the mutual
written agreement of all parties hereto to terminate this Subscription Agreement, (c) if any of the conditions to Closing set forth in
Section 2 of this Subscription Agreement are not satisfied on or prior to the Closing Date, or become incapable of being satisfied
on or prior to the Closing Date, and, as a result thereof, the transactions contemplated by this Subscription Agreement are not consummated
at the Closing, or (d) July 6, 2022, if the Closing has not occurred by such date and the terminating party’s breach was not the
primary reason the Closing failed to occur by such date (the termination events described in clauses (a)–(c) above, collectively,
the “Termination Events”); provided, that nothing herein will relieve any party from liability for any willful
breach hereof prior to the time of termination or common law intentional fraud in the making of any representation or warranty hereunder,
and each party will be entitled to any remedies at law or in equity to recover losses, liabilities or damages arising from such breach
or fraud. The Company shall notify Subscriber of the termination of the Transaction Agreement promptly after the termination thereof.
Upon the occurrence of any Termination Event, except as set forth in the proviso to the first sentence of this Section 6, this
Subscription Agreement shall be void and of no further effect and any portion of the Purchase Price paid by Subscriber to the Company
in connection herewith shall promptly (and in any event within one (1) Business Day) following the Termination Event be returned to Subscriber.


  


Section 7.Trust Account
Waiver. Subscriber hereby acknowledges that as described in the Company’s prospectus relating to its initial public offering
dated October 5, 2020, the Company has established a trust account (the “Trust Account”) containing the proceeds of
its initial public offering (the “IPO”) and from certain private placements occurring simultaneously with the IPO (including
interest accrued from time to time thereon) for the benefit of the Company’s public stockholders and the underwriters of the IPO.
For and in consideration of the Company entering into this Subscription Agreement, and for other good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged, Subscriber hereby (a) agrees that it does not now and shall not at any time
hereafter have any right, title, interest or claim of any kind in or to any assets held in the Trust Account or distributions therefrom,
and shall not make any claim against the Trust Account (including any distributions therefrom), arising out of this Subscription Agreement
regardless of whether such claim arises based on contract, tort, equity or any other theory of legal liability (any and all such claims
are collectively referred to hereafter as the “Released Claims”), (b) irrevocably waives any Released Claims that it
may have against the Trust Account (including any distributions therefrom) now or in the future as a result of, or arising out of, this
Subscription Agreement and (c) agrees it will not seek recourse against the Trust Account with respect to any Released Claims; provided,
however, that nothing in this Section 7 shall (x) serve to limit or prohibit Subscriber’s right to pursue a claim
against the Company for legal relief against assets held outside the Trust Account (so long as such claim would not affect the Company’s
ability to fulfill its obligation to effectuate any redemption right with respect to any securities of the Company), for specific performance
or other equitable relief, (y) serve to limit or prohibit any claims that Subscriber may have in the future against the Company’s
assets or funds that are not held in the Trust Account (including any funds that have been released from the Trust Account and any assets
that have been purchased or acquired with any such funds) (so long as such claim would not affect the Company’s ability to fulfill
its obligation to effectuate any redemption right with respect to any securities of the Company) or (z) be deemed to limit the Subscriber’s
right to distributions from the Trust Account in accordance with the Company’s amended and restated certificate of incorporation
in respect of shares of Class A Common Shares acquired by any means. Subscriber agrees and acknowledges that such irrevocable waiver is
material to this Subscription Agreement and specifically relied upon by the Company and its affiliates to induce the Company to enter
into this Subscription Agreement, and Subscriber further intends and understands such waiver to be valid, binding and enforceable against
Subscriber and each of its affiliates under applicable law. To the extent Subscriber or any of its affiliates commences any action or
proceeding based upon, in connection with, relating to or arising out of any matter relating to the Company or its representatives or
affiliates, which proceeding seeks, in whole or in part, monetary relief against the Company or its representatives or affiliates, Subscriber
hereby acknowledges and agrees that Subscriber’s and its affiliates’ sole remedy shall be against funds held outside of the
Trust Account and that such claim shall not permit Subscriber or its affiliates (or any person claiming on any of their behalves or in
lieu of any of them) to have any claim against the Trust Account (including any distributions therefrom) or any amounts contained therein.


 


Section 8.Indemnity.


 


(a) The
Company agrees to indemnify and hold harmless, to the extent permitted by law, Subscriber, its directors, officers, partners, managers,
members, employees, advisers and agents, and each person who controls Subscriber (within the meaning of the Securities Act or the Exchange
Act) and each affiliate of Subscriber (within the meaning of Rule 405 under the Securities Act) from and against any and all losses, claims,
damages, liabilities, costs and expenses (including, without limitation, any reasonable external attorneys’ fees and expenses incurred
in connection with defending or investigating any such action or claim) that arise out of or are based upon (i) any untrue or alleged
untrue statement of a material fact contained in any Registration Statement, prospectus included in any Registration Statement or preliminary
prospectus or any amendment thereof or supplement thereto or any omission or alleged omission of a material fact required to be stated
therein or necessary to make the statements therein not misleading or (ii) any violation or alleged violation by the Company of the Securities
Act, Exchange Act or any state securities law or any rule or regulation thereunder, except insofar as any such untrue statements, alleged
untrue statements, omissions or alleged omissions are caused by or contained in any information furnished in writing to the Company by
or on behalf of Subscriber expressly for use therein.


 






    	 	14	 



     


    

 


(b) Subscriber
agrees, severally and not jointly with any person that is a party to the Other Subscription Agreements, to indemnify and hold harmless
the Company, its directors, officers, employees and agents, and each person who controls the Company (within the meaning of the Securities
Act or the Exchange Act) and each affiliate of the Company against any losses, claims, damages, liabilities and expenses (including, without
limitation, reasonable external attorneys’ fees and expenses incurred in connection with defending or investigating any such action
or claim) caused by any untrue or alleged untrue statement of a material fact contained in the Registration Statement, prospectus included
in any Registration Statement or preliminary prospectus or any amendment thereof or supplement thereto or any omission or alleged omission
of a material fact required to be stated therein or necessary to make the statements therein not misleading, but only to the extent that
such untrue statement or omission is contained in any information or affidavit so furnished in writing by or on behalf of Subscriber expressly
for use therein. In no event shall the liability of Subscriber be greater in amount than the dollar amount of the net proceeds received
by Subscriber upon the sale of the Subscribed Shares purchased pursuant to this Subscription Agreement giving rise to such indemnification
obligation.


  


(c) Any
person entitled to indemnification herein shall (i) give prompt written notice to the indemnifying party of any claim with respect to
which it seeks indemnification (provided that the failure to give prompt notice shall not impair any person’s right to indemnification
hereunder to the extent such failure has not materially prejudiced the indemnifying party) and (ii) permit such indemnifying party to
assume the defense of such claim with counsel reasonably satisfactory to the indemnified party. If such defense is assumed, the indemnifying
party shall not be subject to any liability for any settlement made by the indemnified party without its consent (not to be unreasonably
withheld, conditioned or delayed). An indemnifying party who elects not to assume the defense of a claim shall not be obligated to pay
the fees and expenses of more than one counsel for all parties indemnified by such indemnifying party with respect to such claim, unless
in the reasonable judgment of legal counsel to any indemnified party a conflict of interest exists between such indemnified party and
any other of such indemnified parties with respect to such claim. No indemnifying party shall, without the consent of the indemnified
party, consent to the entry of any judgment or enter into any settlement which cannot be settled in all respects by the payment of money
(and such money is so paid by the indemnifying party pursuant to the terms of such settlement) or which settlement does not include as
an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a release from all liability in respect
to such claim or litigation.


 


(d) The
indemnification provided for under this Subscription Agreement shall remain in full force and effect regardless of any investigation made
by or on behalf of the indemnified party or any officer, director, employee, agent, affiliate or controlling person of such indemnified
party and shall survive the transfer of the Subscribed Shares purchased pursuant to this Subscription Agreement.


 


(e) If
the indemnification provided under this Section 8 from the indemnifying party is unavailable or insufficient to hold harmless an
indemnified party in respect of any losses, claims, damages, liabilities and expenses referred to herein, then the indemnifying party,
in lieu of indemnifying the indemnified party, subject to Section 8, shall contribute to the amount paid or payable by the indemnified
party as a result of such losses, claims, damages, liabilities and expenses in such proportion as is appropriate to reflect the relative
fault of the indemnifying party and the indemnified party, as well as any other relevant equitable considerations. The relative fault
of the indemnifying party and indemnified party shall be determined by reference to, among other things, whether any action in question,
including any untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact, was made
by, or relates to information supplied by or on behalf of, such indemnifying party or indemnified party, and the indemnifying party’s
and indemnified party’s relative intent, knowledge, access to information and opportunity to correct or prevent such action. The
amount paid or payable by a party as a result of the losses or other liabilities referred to above shall be deemed to include, subject
to the limitations set forth above, any legal or other fees, charges or expenses reasonably incurred by such party in connection with
any investigation or proceeding. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities
Act) shall be entitled to contribution pursuant to this Section 8 from any person who was not guilty of such fraudulent misrepresentation.
Any contribution pursuant to this Section 8(e) by any seller of Subscribed Shares shall be limited in amount to the dollar amount
of net proceeds received by such seller from the sale of such Subscribed Shares pursuant to the Registration Statement. Notwithstanding
anything to the contrary herein, in no event will any party be liable for consequential, special, exemplary or punitive damages in connection
with this Subscription Agreement.

notices, requests, demands, claims, and other communications hereunder shall be in writing. Any notice, request, demand, claim, or other
communication hereunder shall be deemed duly given (i) when delivered personally to the recipient, (ii) when sent by electronic mail,
on the date of transmission to such recipient (with no mail undeliverable or other rejection notice), (iii) one (1) Business Day after
being sent to the recipient by reputable overnight courier service (charges prepaid), or (iv) four (4) Business Days after being mailed

recipient at its address or electronic mail address, as applicable, specified on the signature page hereof or to such electronic mail
address or address as subsequently modified by written notice given in accordance with this Section 9(a).


 


(b) Subscriber
acknowledges that (i) the Company will rely on the acknowledgments, understandings, agreements, representations and warranties of Subscriber
contained in this Subscription Agreement and (ii) the Placement Agent will rely on the acknowledgments, understandings, agreements, representations
and warranties of Subscriber contained in Section 4 of this Subscription Agreement. Prior to the Closing, Subscriber agrees to promptly
notify the Company and the Placement Agent if it becomes aware that any of the acknowledgments, understandings, agreements, representations
and warranties of Subscriber set forth herein are no longer accurate in all material respects. Subscriber acknowledges and agrees that
the purchase by Subscriber of Subscribed Shares from the Company will constitute a reaffirmation of the acknowledgments, understandings,
agreements, representations and warranties herein (as modified by any such notice) by Subscriber as of the time of such purchase. The
Company acknowledges that Subscriber will rely on the acknowledgments, understandings, agreements, representations and warranties of the
Company contained in this Subscription Agreement. Each of the Company and Subscriber further acknowledge and agree that the Placement
Agent is a third party beneficiary of the representations and warranties of the Company and Subscriber contained in Section 3 and Section
4, respectively, of this Subscription Agreement.


 


(c) Each
of the Company, the Placement Agent and Subscriber is irrevocably authorized to produce this Subscription Agreement or a copy hereof to
any interested party in any administrative or legal proceeding or official inquiry with respect to the matters covered hereby.


 


(d) Each
party shall pay all of its own expenses in connection with this Subscription Agreement and the transactions contemplated herein.


 


(e) Neither
this Subscription Agreement nor any rights that may accrue to Subscriber hereunder (other than the Subscribed Shares acquired hereunder
and Subscriber’s rights under Section 5 hereof) may be transferred or assigned. Neither this Subscription Agreement nor any
rights that may accrue to the Company hereunder may be transferred or assigned (provided, that, for the avoidance of doubt, the
Company may transfer the Subscription Agreement and its rights hereunder solely in connection with the consummation of the Transactions
and exclusively to another entity under the control of, or under common control with, the Company). Notwithstanding the foregoing, Subscriber
may assign all or any portion of its rights and obligations under this Subscription Agreement to one or more of its affiliates or to other
investment funds or accounts managed or advised by the investment manager who acts on behalf of Subscriber, or, with the Company’s
prior written consent, to another person, provided that (i) such assignee(s) agrees in writing to be bound by the terms hereof,
and upon such assignment by Subscriber, the assignee(s) shall become Subscriber hereunder and have the rights and obligations and be deemed
to make the representations and warranties of Subscriber provided for herein to the extent of such assignment and (ii) no such assignment
shall relieve Subscriber of its obligations hereunder if any such assignee fails to perform such obligations unless expressly agreed to
in writing by the Company.


 




    	 	16	 



     


    

 


(f) All
the agreements, representations and warranties made by each party hereto in this Subscription Agreement shall survive the Closing. For
the avoidance of doubt, if for any reason the Closing does not occur prior to the consummation of the Transactions, all representations,
warranties, covenants and agreements of the parties hereunder shall survive the consummation of the Transactions and remain in full force
and effect.


 


(g) The
Company may request from Subscriber such additional information as the Company may reasonably deem necessary to evaluate the eligibility
of Subscriber to acquire the Subscribed Shares, and Subscriber shall provide such information as may be reasonably requested provided
that the Company agrees to keep any such information provided by Subscriber confidential. Subscriber acknowledges that subject to the
conditions set forth in Section 9(s), the Company may file a copy of this Subscription Agreement with the Commission as an exhibit
to a report of the Company, or a registration statement or proxy statement of the Company.


 


(h) This
Subscription Agreement may not be amended, modified or waived except by an instrument in writing, signed by each of the parties hereto.


 


(i) This
Subscription Agreement constitutes the entire agreement, and supersedes all other prior agreements, understandings, representations and
warranties, both written and oral, among the parties, with respect to the subject matter hereof.


 


(j) Except
as otherwise provided herein (including the next sentence hereof), this Subscription Agreement is intended for the benefit of the parties
hereto and their respective affiliates and their respective heirs, executors, administrators, successors, legal representatives, and permitted
assigns and is not for the benefit of, nor may any provision hereof be enforced by, any other person. Except as set forth in Section
8, Section 9(b), Section 9(c), Section 9(e), and this Section 9(j), this Subscription Agreement shall
not confer any rights or remedies upon any person other than the parties hereto, and their respective successor and assigns, and the parties
hereto acknowledge that such persons so referenced are third party beneficiaries of this Subscription Agreement for the purposes of, and
to the extent of, the rights granted to them, if any, pursuant to the applicable provisions.


 


(k) The
parties hereto acknowledge and agree that (i) this Subscription Agreement is being entered into in order to induce the Company to execute
and deliver the Transaction Agreement and (ii) irreparable damage would occur in the event that any of the provisions of this Subscription
Agreement were not performed in accordance with their specific terms or were otherwise breached and that money or other legal remedies
would not be an adequate remedy for such damage. It is accordingly agreed that the parties shall be entitled to equitable relief, including
in the form of an injunction or injunctions to prevent breaches or threatened breaches of this Subscription Agreement and to enforce specifically
the terms and provisions of this Subscription Agreement, this being in addition to any other remedy to which such party is entitled at
law, in equity, in contract, in tort or otherwise. The parties hereto acknowledge and agree that the Company shall be entitled to specifically
enforce Subscriber’s obligations to fund the Purchase Price and the provisions of the Subscription Agreement, in each case, on the
terms and subject to the conditions set forth herein. The parties hereto further acknowledge and agree: (x) to waive any requirement for
the security or posting of any bond in connection with any such equitable remedy; (y) not to assert that a remedy of specific enforcement
pursuant to this Section 9(k) is unenforceable, invalid, contrary to applicable law or inequitable for any reason; and (z) to waive
any defenses in any action for specific performance, including the defense that a remedy at law would be adequate.


 




    	 	17	 



     


    

 


(l)  If
any provision of this Subscription Agreement shall be invalid, illegal or unenforceable, the validity, legality or enforceability of the
remaining provisions of this Subscription Agreement shall not in any way be affected or impaired thereby and shall continue in full force
and effect.


 


(m) No
failure or delay by a party hereto in exercising any right, power or remedy under this Subscription Agreement, and no course of dealing
between the parties hereto, shall operate as a waiver of any such right, power or remedy of such party. No single or partial exercise
of any right, power or remedy under this Subscription Agreement by a party hereto, nor any abandonment or discontinuance of steps to enforce
any such right, power or remedy, shall preclude such party from any other or further exercise thereof or the exercise of any other right,
power or remedy hereunder. The election of any remedy by a party hereto shall not constitute a waiver of the right of such party to pursue
other available remedies. No notice to or demand on a party not expressly required under this Subscription Agreement shall entitle the
party receiving such notice or demand to any other or further notice or demand in similar or other circumstances or constitute a waiver
of the rights of the party giving such notice or demand to any other or further action in any circumstances without such notice or demand.


 


(n) This
Subscription Agreement may be executed and delivered in one or more counterparts (including by facsimile or electronic mail or in.pdf)
and by different parties in separate counterparts, with the same effect as if all parties hereto had signed the same document. All counterparts
so executed and delivered shall be construed together and shall constitute one and the same agreement.


 


(o) This
Subscription Agreement shall be governed by, and construed in accordance with, the laws of the State of New York, without regard to the
principles of conflicts of laws that would otherwise require the application of the law of any other state.


 


(p) EACH
PARTY AND ANY PERSON ASSERTING RIGHTS AS A THIRD PARTY BENEFICIARY HEREBY WAIVES ITS RESPECTIVE RIGHTS TO A TRIAL BY JURY OF ANY CLAIM
OR CAUSE OF ACTION BASED UPON OR ARISING OUT OR RELATED TO THIS SUBSCRIPTION AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY IN ANY
ACTION, PROCEEDING OR OTHER LITIGATION OF ANY TYPE BROUGHT BY ANY PARTY AGAINST ANY OTHER PARTY OR ANY AFFILIATE OF ANY OTHER SUCH PARTY,
WHETHER WITH RESPECT TO CONTRACT CLAIMS, TORT CLAIMS OR OTHERWISE. THE PARTIES AGREE THAT ANY SUCH CLAIM OR CAUSE OF ACTION SHALL BE TRIED
BY A COURT TRIAL WITHOUT A JURY. WITHOUT LIMITING THE FOREGOING, THE PARTIES FURTHER AGREE THAT THEIR RESPECTIVE RIGHT TO A TRIAL BY JURY
IS WAIVED BY OPERATION OF THIS SECTION AS TO ANY ACTION, COUNTERCLAIM OR OTHER PROCEEDING WHICH SEEKS, IN WHOLE OR IN PART, TO CHALLENGE
THE VALIDITY OR ENFORCEABILITY OF THIS SUBSCRIPTION AGREEMENT OR ANY PROVISION HEREOF. THIS WAIVER SHALL APPLY TO ANY SUBSEQUENT AMENDMENTS,
RENEWALS, SUPPLEMENTS OR MODIFICATIONS TO THIS SUBSCRIPTION AGREEMENT.


 




    	 	18	 



     


    

 


(q) The
parties agree that all disputes, legal actions, suits and proceedings arising out of or relating to this Subscription Agreement must be
brought exclusively in the United States District Court for the Southern District of New York, the Supreme Court of the State of New York
and the federal courts of the United States of America located in the State of New York (collectively the “Designated Courts”).
Each party hereby consents and submits to the exclusive jurisdiction of the Designated Courts. No legal action, suit or proceeding with
respect to this Subscription Agreement may be brought in any other forum. Each party hereby irrevocably waives all claims of immunity
from jurisdiction, and any objection which such party may now or hereafter have to the laying of venue of any suit, action or proceeding
in any Designated Court, including any right to object on the basis that any dispute, action, suit or proceeding brought in the Designated
Courts has been brought in an improper or inconvenient forum or venue. Each of the parties also agrees that delivery of any process, summons,
notice or document to a party hereof in compliance with Section 9(a) of this Subscription Agreement shall be effective service
of process for any action, suit or proceeding in a Designated Court with respect to any matters to which the parties have submitted to
jurisdiction as set forth above.


 


(r) This
Subscription Agreement may only be enforced against, and any claim, action, suit or other legal proceeding based upon, arising out of,
or related to this Subscription Agreement, or the negotiation, execution or performance of this Subscription Agreement, may only be brought
against the entities that are expressly named as parties or third party beneficiaries hereto and then only with respect to the specific
obligations set forth herein with respect to such party or third party beneficiary. No past, present or future director, officer, employee,
incorporator, manager, member, partner, stockholder, affiliate, agent, attorney or other representative of any party hereto or of any
affiliate of any party hereto, or any of their successors or permitted assigns, shall have any liability for any obligations or liabilities
of any party hereto under this Subscription Agreement or for any claim, action, suit or other legal proceeding based on, in respect of
or by reason of the transactions contemplated hereby.


 


(s) The
Company shall, by 9:00 a.m., New York City time, on the first (1st) Business Day immediately following the date of this Subscription
Agreement, issue one or more press releases or file with the Commission a Current Report on Form 8-K (collectively, the
“Disclosure Document”) disclosing all material terms of the transactions contemplated hereby and by the Other
Subscription Agreements, the Note Subscription Agreements, the Transactions and any other material, nonpublic information regarding
the Transactions, the Company, or Target that the Company provided to the Subscriber prior to the date hereof. Upon the issuance of
the Disclosure Document, to the Company’s knowledge, Subscriber shall not be in possession of any material, nonpublic
information received from the Company or any of its officers, directors, or employees or agents, and Subscriber shall no longer be
subject to any confidentiality or similar obligations under any current agreement, whether written or oral with the Company, the
Placement Agent, or any of their respective affiliates in connection with the Transactions. Notwithstanding anything in this
Subscription Agreement to the contrary, the Company (i) shall not publicly disclose the name of Subscriber or any of its affiliates
or advisers, or include the name of Subscriber or any of its affiliates or advisers in any press release, investor presentations or
marketing materials, without the prior written consent of Subscriber and (ii) shall not publicly disclose the name of Subscriber or
any of its affiliates or advisers, or include the name of Subscriber or any of its affiliates or advisers in any filing with the
Commission or any regulatory agency or trading market, without the prior written consent of Subscriber, except as required by the
federal securities law, regulatory agency or under the regulations of NYSE or Nasdaq, as applicable, in which case the Company shall
provide Subscriber with prior written notice of such disclosure permitted hereunder. Subscriber will promptly provide any
information reasonably requested by the Company or any of its affiliates for any required regulatory application or filing to be
made or required regulatory approval sought in connection with the Transactions (including filings with the Commission). The
Subscriber may disclose the name of the Company, Target, and/or any other parties associated with the Subscription or Transactions
and the terms of this Subscription Agreement, as required by federal securities laws and regulations, any regulatory agency, or
under the regulations of NYSE or Nasdaq, as applicable, or otherwise to the extent consistent with the Subscriber’s public
filings and disclosures regarding similar transactions.


 




    	 	19	 



     


    

 


(t) The
obligations of Subscriber under this Subscription Agreement are several and not joint with the obligations of any Other Subscriber or
any other investor under the Other Subscription Agreements, and Subscriber shall not be responsible in any way for the performance of
the obligations of any Other Subscriber under this Subscription Agreement or any Other Subscriber or other investor under the Other Subscription
Agreements. The decision of Subscriber to purchase Subscribed Shares pursuant to this Subscription Agreement has been made by Subscriber
independently of any Other Subscriber or any other investor and independently of any information, materials, statements or opinions as
to the business, affairs, operations, assets, properties, liabilities, results of operations, condition (financial or otherwise) or prospects
of the Company or any of its subsidiaries which may have been made or given by any Other Subscriber or investor or by any agent or employee
of any Other Subscriber or investor, and neither Subscriber nor any of its agents or employees shall have any liability to any Other Subscriber
or investor (or any other person) relating to or arising from any such information, materials, statements or opinions. Nothing contained
herein or in any Other Subscription Agreement, and no action taken by Subscriber or investor pursuant hereto or thereto, shall be deemed
to constitute Subscriber and Other Subscribers or other investors as a partnership, an association, a joint venture or any other kind
of entity, or create a presumption that Subscriber and Other Subscribers or other investors are in any way acting in concert or as a group
with respect to such obligations or the transactions contemplated by this Subscription Agreement and the Other Subscription Agreements.
Subscriber acknowledges that no Other Subscriber has acted as agent for Subscriber in connection with making its investment hereunder
and no Other Subscriber will be acting as agent of Subscriber in connection with monitoring its investment in the Subscribed Shares or
enforcing its rights under this Subscription Agreement. Subscriber shall be entitled to independently protect and enforce its rights,
including without limitation the rights arising out of this Subscription Agreement, and it shall not be necessary for any Other Subscriber
or investor to be joined as an additional party in any proceeding for such purpose.


 


(u) Subscriber
hereby acknowledges and agrees that it will not, nor will any person acting at Subscriber’s direction or pursuant to any understanding
with Subscriber, directly or indirectly offer, sell, pledge, contract to sell, sell any option, engage in hedging activities or execute
any “short sales” as defined in Rule 200 of Regulation SHO under the Exchange Act of the Subscribed Shares until the consummation
of the Transactions (or such earlier termination of this Subscription Agreement in accordance with its terms). For the avoidance of doubt,
this Section 9(u) shall not apply to any sale (including the exercise of any redemption right) of securities of the Company (i)
held by Subscriber, its controlled affiliates or any person or entity acting on behalf of Subscriber or any of its controlled affiliates
prior to the execution of this Subscription Agreement or (ii) purchased by Subscriber, its controlled affiliates or any person or entity
acting on behalf of Subscriber or any of its controlled affiliates in open market transactions after the execution of this Subscription
Agreement. Notwithstanding the foregoing, (1) nothing herein shall prohibit other entities under common management with Subscriber that
have no knowledge of this Subscription Agreement or of Subscriber’s participation in the subscription (including Subscriber’s
controlled affiliates and/or affiliates) from entering into any short sales and (2) in the case of a Subscriber that is a multi-managed
investment vehicle whereby separate portfolio managers manage separate portions of such Subscriber’s assets and the portfolio managers
have no knowledge of the investment decisions made by the portfolio managers managing other portions of such Subscriber’s assets,
this Section 9(u) shall only apply with respect to the portion of assets managed by the portfolio manager that made the investment
decision to purchase the Subscribed Shares covered by this Subscription Agreement.


 


(v) If
Subscriber is a Massachusetts Business Trust, a copy of the Declaration of Trust of the Subscriber or any affiliate thereof is on file
with the Secretary of State of the Commonwealth of Massachusetts and notice is hereby given that the Subscription Agreement is executed
on behalf of the trustees of the Subscriber or any affiliate thereof as trustees and not individually and that the obligations of the
Subscription Agreement are not binding on any of the trustees, officers or stockholders of the Subscriber or any affiliate thereof individually
but are binding only upon the Subscriber or any affiliate thereof and its assets and property.
