shall have the meanings ascribed thereto in the Business Combination Agreement), by and among the Issuer, S-IV Sub, Inc., a Delaware
corporation (“Merger Sub”), and Mount Sinai Genomics, Inc. (d/b/a Sema4) (together with its direct and indirect

and the Issuer desires to issue and sell to Subscriber the Acquired Shares in consideration of the payment of the Purchase Price
by or on behalf of Subscriber to the Issuer on or prior to the Closing (as defined below);

 

WHEREAS,
the Issuer and Subscriber are executing and delivering this Subscription Agreement in reliance upon the exemption from securities
registration afforded by Section 4(a)(2) of the Securities Act of 1933, as amended (the “Securities Act”);

 

WHEREAS,
in connection with the Transactions, certain other “qualified institutional buyers” (as defined in Rule 144A under
the Securities Act) or institutional “accredited investors” (as such term is defined in Rule 501 under the Securities
Act) (each an “Other Subscriber”), have (severally and not jointly) entered into separate subscription agreements
with the Issuer (the “Other Subscription Agreements”), pursuant to which such investors have agreed to purchase
Class A Shares on the Closing Date (as defined below) at the Per Share Price (the “Other Acquired Shares”);

 

WHEREAS,

Agreements equals 35 million Class A Shares; and

 

WHEREAS,
the aggregate amount of proceeds to the Issuer in connection with the purchase and sale of the Acquired Shares and the Other Acquired

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:

 

1. Subscription.
Subject to the terms and conditions hereof, Subscriber hereby agrees to subscribe for and purchase, and the Issuer hereby agrees
to issue and sell to Subscriber, upon the payment of the Purchase Price, the Acquired Shares (such subscription and issuance,
the “Subscription”). 

 

     

     

    

 

2. Closing.

 

(a) The
closing of the Subscription contemplated hereby (the “Closing”) is contingent upon the substantially concurrent
consummation of the Transactions and shall occur immediately prior thereto. Not less than five (5) business days prior to
the scheduled closing date of the Transactions (the “Closing Date”), the Issuer shall provide written notice
to Subscriber (the “Closing Notice”) of such Closing Date. Subscriber shall deliver to the Issuer no later
than one (1) business day before the Closing Date (as specified in the Closing Notice or such other date as otherwise agreed to
by the Issuer and the Subscriber, the “Purchase Price Payment Date”) the Purchase Price for the Acquired Shares
by wire transfer of U.S. dollars in immediately available funds (i) to the account specified by the Issuer in the Closing Notice,
to be held in a third-party escrow account (the “Escrow Account”) designated by the Issuer prior to the Closing
Date for the benefit of the Subscriber until the Closing Date or (ii) in the case of a Subscriber that is an “investment
company” registered under the Investment Company Act of 1940, as amended, to an account specified by the Issuer otherwise
mutually agreed by the Subscriber and the Issuer (“Alternative Settlement Procedures”). For the avoidance of
doubt, mutually agreeable Alternative Settlement Procedures shall include, without limitation, the Subscriber delivering to the
Issuer on the Closing Date the Purchase Price for the Acquired Shares by wire transfer of U.S. dollars in immediately available
funds to the account specified by the Issuer in the Closing Notice against delivery to the undersigned of the Acquired Shares
in book entry form as set forth in the following sentence. On the Closing Date, the Issuer shall deliver to Subscriber (1) the
Acquired Shares in book entry form (or, if requested by the Subscriber in writing in advance of the Closing, in certificated form,
duly executed on behalf of the Issuer and countersigned by the Issuer’s transfer agent (the “Transfer Agent”)),
free and clear of any liens or other restrictions whatsoever (other than those arising under state or federal securities laws),
in the name of Subscriber (or its nominee in accordance with its delivery instructions) or to a custodian designated by Subscriber,
as applicable, and (2) a copy of the records of the Transfer Agent showing Subscriber as the owner of the Acquired Shares
on and as of the Closing Date (the “Subscriber’s Deliveries”). Unless otherwise provided pursuant to
Alternative Settlement Procedures, upon the transfer of the Subscriber’s Deliveries by the Issuer to the Subscriber (or
its nominee in accordance with its delivery instructions), the Issuer shall, or shall cause the escrow agent for the Escrow Account
to, on the Closing Date, release the Purchase Price from the Escrow Account to the Issuer. In the event the closing of the Transactions
does not occur within two (2) business days of the Closing Date specified in the Closing Notice, unless otherwise agreed by the
Issuer and the Subscriber, the Issuer shall, or shall cause the escrow agent for the Escrow Account to, promptly (but not later
than two (2) business days thereafter) return the Purchase Price to Subscriber by wire transfer of U.S. dollars in immediately
available funds to the account specified by Subscriber, and any book entries or share certificates shall be deemed cancelled.

 

(b) The
Closing shall be subject to the satisfaction, or valid waiver by each of the parties hereto, of the conditions that, on the Closing
Date:

 

(i) solely
with respect to Subscriber, the representations and warranties made by the Issuer (other than the representations and warranties
set forth in Section 3(b), Section 3(c) and Section 3(h)) in this Subscription Agreement shall be true and

an earlier date, which shall be true and correct in all material respects as of such date, and other than those representations
and warranties that are qualified as to materiality or Material Adverse Effect (as defined below), which shall be true and correct
in all respects as of the Closing Date), after giving effect to the consummation of the Transactions, and the representations
and warranties made by the Issuer set forth in Section 3(b), Section 3(c) and Section 3(h) shall be true
and correct in all respects as of the Closing Date (other than those representations and warranties expressly made as of an earlier
date, which shall be true and correct in all respects as of such date), in each case without giving effect to the consummation
of the Transactions;

 

    2

     

    

 

(ii) solely

as of an earlier date, which shall be true and correct in all material respects as of such date, and other than those representations
and warranties that are qualified as to materiality or Material Adverse Effect, which shall be true and correct in all respects
as of the Closing Date), in each case without giving effect to the consummation of the Transactions;

 

(iii) solely
with respect to the Issuer, Subscriber shall have delivered the Purchase Price in compliance with the terms of this Subscription
Agreement;

 

(iv) no
governmental authority having applicable jurisdiction shall have enacted, issued, promulgated, enforced or entered any material
judgment, order, law, rule or regulation (whether temporary, preliminary or permanent) which is then in effect and has the effect
of restraining, enjoining or otherwise prohibiting or making illegal the consummation of the transactions contemplated by this
Subscription Agreement;

 

(v) no
suspension of the qualification of the Class A Shares for offering or sale or trading in any applicable jurisdiction, no suspension
or removal from listing of the Acquired Shares on The Nasdaq Capital Market (“Nasdaq”) and no initiation or
threatening of any proceedings for any of such purposes or delisting, shall have occurred;

 

(vi) the
Issuer’s stockholders shall have approved the issuance of the Acquired Shares and Other Acquired Shares as and if required
by Nasdaq rules;

 

(vii) solely
with respect to Subscriber, the Issuer shall have filed with Nasdaq a true and complete Notification Form: Listing of Additional
Shares covering the Acquired Shares and Other Acquired Shares;

 

(viii) all
conditions precedent to the closing of the Transactions set forth in the Business Combination Agreement, shall have been satisfied
or waived (as determined by the Business Combination Agreement and related documentation)(other than those conditions that may
only be satisfied at the closing of the Transactions, but subject to satisfaction or waiver by such party of such conditions as
of the closing of the Transactions), and the closing of the Transactions shall be scheduled to occur substantially concurrently
with or immediately following the Closing; and

 

(ix) solely
with respect to the Subscriber, there shall have been no amendment, waiver or modification to the Other Subscription Agreements
that materially benefits any Other Subscriber thereunder unless the Subscriber has been offered substantially the same benefits.

 

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

 

(i) the
Issuer shall have performed, satisfied and complied in all material respects with the covenants, agreements and conditions required
by this Subscription Agreement to be performed, satisfied or complied with by the Issuer at or prior to the Closing, except where
the failure of such performance or compliance would not reasonably be expected to prevent, materially delay, or materially impair
the ability of the Issuer to consummate the Closing;

 

    3

     

    

 

(ii) since
the date of this Subscription Agreement and as of the Closing Date, there has been no Company Material Adverse Effect (as such
term is defined in the Business Combination Agreement)

 

(iii) except
to the extent consented to in writing by Subscriber, the Business Combination Agreement (as filed with the Commission on or immediately
following the date hereof) shall not have been amended, modified, supplemented or waived in a manner that would reasonably be
expected to materially and adversely affect the economic benefits that Subscriber would reasonably expect to receive under this
Subscription Agreement; and

 

(d) Upon
the terms and subject to the conditions set forth in this Subscription Agreement, Subscriber and the Issuer shall use commercially
reasonable efforts to take, or cause to be taken, all actions, and to do, or cause to be done, and to reasonably assist and cooperate
with the other party hereto in doing, all things reasonably necessary, proper or advisable under applicable legal requirements
to consummate and make effective, in the most expeditious manner practicable, the transactions contemplated by this Subscription
Agreement.

 

3. Issuer
Representations and Warranties. The Issuer represents and warrants to the Subscriber that:

 

(a) The
Issuer has been duly incorporated and is validly existing as a corporation in good standing under the laws of the State of Delaware,
with corporate power and authority to own, lease and operate its properties and conduct its business as presently conducted and
to enter into, deliver and perform its obligations under this Subscription Agreement.

and bylaws (each, as amended concurrently with the Closing) or under the laws of the State of Delaware or otherwise.

 

(c) This
Subscription Agreement, the Business Combination Agreement and the Other Subscription Agreements (collectively, the “Transaction
Documents”) have been duly authorized, executed and delivered by the Issuer and, assuming that the Transaction Documents
have been duly authorized, executed and delivered by the other parties thereto, are valid and binding obligations of the Issuer,
and are enforceable against it in accordance with their terms, except as may be limited or otherwise affected by (i) bankruptcy,
insolvency, reorganization, fraudulent conveyance, moratorium or other laws relating to or affecting the rights of creditors generally,
and (ii) principles of equity, whether considered at law or equity.

 

(d) The
execution, delivery and performance of this Subscription Agreement and the other Transaction Documents, including the issuance
and sale of the Acquired Shares and the consummation of the Transactions and other transactions contemplated hereby and thereby,
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 Issuer pursuant
to the terms of (i) any indenture, mortgage, deed of trust, loan agreement, lease, license or other agreement or instrument
to which the Issuer is a party or by which the Issuer is bound or to which any of the property or assets of the Issuer is subject;
(ii) the organizational documents of the Issuer; or (iii) any statute or any judgment, order, rule or regulation of
any court or governmental agency, taxing authority or regulatory body, domestic or foreign, having jurisdiction over the Issuer
or any of its properties, that, in the case of clause (i) or (iii), would reasonably be expected to have a Material Adverse Effect.
For purposes of this Subscription Agreement, a “Material Adverse Effect” means an event, change, development, occurrence,
condition or effect with respect to the Issuer and its subsidiaries, taken together as a whole (on a consolidated basis), that,
individually or in the aggregate, would reasonably be expected to have a material adverse effect on the business, properties,
financial condition, stockholders’ equity or results of operations of the Issuer or Target or their respective subsidiaries
individually or taken as a whole and including the combined company after giving effect to the Transactions, or materially affects
the Issuer’s ability to consummate the (i) transactions contemplated hereby, including the issuance and sale of the Acquired
Shares or (ii) the Transactions.

 

    4

     

    

 

(e) There
are no securities or instruments issued by or to which the Issuer is a party containing anti-dilution or similar provisions that
will be triggered by the issuance of (i) the Acquired Shares, (ii) the shares to be issued pursuant to any Other Subscription
Agreement or (iii) the shares to be issued pursuant to the Transactions, in each case, that have not been or will not be validly
waived on or prior to the Closing Date, including such provisions in the Issuer’s Class B common stock, par value $0.0001
per share (the “Class B Shares”), pursuant to the terms of the Issuer’s certificate of incorporation.

 

(f) The
Issuer is not in default or violation (and no event has occurred which, with notice or the lapse of time or both, would constitute
a default or violation) of any term, condition or provision of (i) the organizational documents of the Issuer, (ii) any
loan or credit agreement, guarantee, note, bond, mortgage, indenture, lease or other agreement, permit, franchise or license to
which, as of the date of this Subscription Agreement, the Issuer is a party or by which the Issuer’s properties or assets
are bound or (iii) any statute or any judgment, order, rule or regulation of any court or governmental agency, taxing authority
or regulatory body, domestic or foreign, having jurisdiction over the Issuer or any of its properties, except, in the case of
clauses (ii) and (iii), for defaults or violations that have not had and would not reasonably be expected to have, individually
or in the aggregate, a Material Adverse Effect.

 

(g) The
Issuer 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 or other person in

    5

     

    

 

(h) As
of the date of this Subscription Agreement and as of immediately prior to the Closing Date, the authorized capital stock of the
Issuer consists of (i) 1,000,000 shares of preferred stock, par value $0.0001 per share (“Preferred Stock”)
and (ii) 400,000,000 shares of common stock, par value $0.0001 per share (the “Common Stock”), including (1)
380,000,000 Class A Shares and (2) 20,000,000 Class B Shares. As of the date of this Subscription Agreement, (i) no shares
of Preferred Stock are issued and outstanding, (ii) 44,275,000 Class A Shares are issued and outstanding, (iii) 11,068,750
Class B Shares are issued and outstanding and (iv) 14,758,333 redeemable warrants and 7,236,667 private placement warrants
are outstanding. All (i) issued and outstanding Class A Shares and Class B Shares have been duly authorized and validly issued,
are fully paid and are non-assessable and are not subject to and were not issued in violation of any preemptive rights and (ii)
outstanding warrants have been duly authorized and validly issued, are fully paid and are not subject to and were not issued in
violation of any preemptive rights. Except as set forth above and pursuant to the Other Subscription Agreements and the Business
Combination Agreement, there are no outstanding options, warrants or other rights to subscribe for, purchase or acquire from the
Issuer any shares of Common Stock or other equity interests in the Issuer, or securities convertible into or exchangeable or exercisable
for such equity interests. As of the date hereof, other than Merger Sub, the Issuer 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 Issuer is a party or by which
it is bound relating to the voting of any securities of the Issuer, other than (i) as set forth in the SEC Reports and (ii) as
contemplated by the Business Combination Agreement. Except as disclosed in the SEC Reports, as of the date hereof, the Issuer
had no outstanding indebtedness and will not have any outstanding long-term indebtedness as of the Closing Date.

 

(i) The
Issuer is in compliance with all applicable laws and has not received any written communication from a governmental entity that
alleges that the Issuer is not in compliance with or is in default or violation of any applicable law, except where such non-compliance,
default or violation would not, individually or in the aggregate, be reasonably likely to be material.

 

(j) The
issued and outstanding Class A Shares are registered pursuant to Section 12(b) of the Securities Exchange Act of 1934,
as amended (the “Exchange Act”), and are listed for trading on Nasdaq under the symbol “CMLF” (it
being understood that the trading symbol will be changed in connection with the Transaction). There is no suit, action, proceeding
or investigation pending or, to the knowledge of the Issuer, threatened against the Issuer by Nasdaq or the Commission with respect
to any intention by such entity to deregister the Class A Shares or prohibit or terminate the listing of the Class A Shares
on Nasdaq, excluding, for the purposes of clarity, the customary ongoing review by Nasdaq of the Issuer’s continued listing
application in connection with the Transactions. The Issuer has taken no action that is designed to terminate or is reasonably
expected to result in the termination of the registration of the Class A Shares under the Exchange Act or the listing of
the Class A Shares on Nasdaq and is in compliance in all material respects with the listing requirements of Nasdaq.

 

(k) Assuming
the accuracy of Subscriber’s representations and warranties set forth in Section 4 of this Subscription Agreement
and each of the Other Subscription Agreements of the Other Subscribers under their respective Other Subscription Agreement, no
registration under the Securities Act is required for the offer and sale of the Acquired Shares or the Other Acquired Shares by
the Issuer to Subscriber and to the Other Subscribers, as appropriate, in the manner contemplated by this Subscription Agreement
and the Other Subscription Agreements. The Acquired Shares and the Other Acquired 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.

 

    6

     

    

 

(l) Each
report, statement and form (including exhibits and other information incorporated therein) filed by the Issuer with the Commission
under Sections 13(a), 14(a) or 15(d) of the Exchange Act or filed pursuant to the Securities Act since its initial registration
of the Class A Shares (the “SEC Reports”) when filed complied in all material respects with the requirements
of the Securities Act and the Exchange Act and the rules and regulations of the Commission promulgated thereunder. None of the
SEC Reports filed under the Exchange Act (except to the extent that information contained in any SEC Report has been superseded
by a later timely filed SEC Report) contained, when filed, any untrue statement of a material fact or omitted to state a material
fact required to be stated therein or necessary to make the statements therein not misleading, in the case of any SEC Report that
is a registration statement, or included, when filed, any untrue statement of a material fact or omitted to state a material fact
necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading, in
the case of all other SEC Reports; provided, that, with respect to the proxy statement to be filed by the Issuer with respect
to the Transactions included in any SEC Report or filed as an exhibit thereto, the representation and warranty in this sentence
is made to the Issuer’s knowledge. The Issuer has timely filed each SEC Report that the Issuer was required to file with
the Commission since its inception. There are no material outstanding or unresolved comments in comment letters from the Commission
staff with respect to any of the Issuer’s SEC Reports. In addition, the Issuer has made available to Subscriber (including
via the Commission’s EDGAR system) a copy of the SEC Reports since its initial registration of the Class A Shares with the
Commission. Each of the financial statements (including, in each case, any notes thereto) contained in the SEC Reports was prepared
in accordance with U.S. generally accepted accounting principles applied on a consistent basis throughout the periods indicated
(except as may be indicated in the notes thereto or, in the case of unaudited statements, as permitted by Form 10-Q of the Commission),
each complied in all material respects with the rules and regulations of the Commission with respect thereto as in effect at the
time of filing and each fairly presents, in all material respects, the financial position, results of operations and cash flows
of the Issuer as at the respective dates thereof and for the respective periods indicated therein.

 

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

 

(n) Except
for placement fees payable to the Placement Agent (as defined below), the Issuer has not paid, and is not obligated to pay, any
brokerage, finder’s or other fee or commission in connection with its issuance and sale of the Acquired Shares, including,
for the avoidance of doubt, any fee or commission payable to any stockholder or affiliate of the Issuer and such relationships
shall not have any liability on the Subscriber. The Issuer is solely responsible for the payment of any fees, costs, expenses
and commissions of the Placement Agent.

 

(o) Except
as provided in this Subscription Agreement and the Other Subscription Agreements, none of the Issuer, its subsidiaries or any
of their affiliates, nor any person acting on their behalf has, directly or indirectly, made any offers or sales of any security
or solicited any offers to buy any security, under circumstances that would require registration of the issuance of any of the
Acquired Shares under the Securities Act, whether through integration with prior offerings pursuant to Rule 502(a) of the Securities
Act or otherwise.

 

(p) Neither
the Issuer nor any of its subsidiaries has taken any steps to seek protection pursuant to any law or statute relating to bankruptcy,
insolvency, reorganization, receivership, liquidation, administration or winding up or failed to pay its debts when due, nor does
the Issuer or any subsidiary have any knowledge or reason to believe that any of their respective creditors intend to initiate
involuntary bankruptcy proceedings or seek to commence an administration.  

 

(q) The
Issuer has not entered into any side letter or similar agreement with any Other Subscriber relating to such Other Subscriber’s
purchase of its respective Other Acquired Shares other than the Other Subscription Agreements, the Registration Rights Agreement
to the extent that a Subscriber is party thereto, or any side letter or similar agreement unrelated to such Other Acquired Shares
or whose terms are not materially more advantageous to such Other Subscriber than the Subscriber hereunder. The Other Subscription
Agreements (and any amendments thereto) reflect the same Per Share Price and other material terms with respect to the purchase
of the Other Acquired Shares that are no more favorable to such Other Subscriber thereunder than the terms of this Subscription
Agreement other than terms particular to the regulatory requirements of such subscriber or its affiliates or related funds.

 

    7

     

    

 

(r) The
Issuer is not, and immediately after receipt of payment for the Acquired Shares, and consummation of the Transactions, will not
be, an “investment company” within the meaning of the Investment Company Act of 1940, as amended.

 

(s) There
has been no action taken by the Issuer, or, to the knowledge of the Issuer, any officer, director, equityholder, manager, employee,
agent or representative of the Issuer, in each case, acting on behalf of the Issuer, in violation of any applicable Anti-Corruption
Laws (as herein defined), (i) the Issuer has not been convicted of violating any Anti-Corruption Laws or subjected to any investigation
by a governmental authority for violation of any applicable Anti-Corruption Laws, (ii) the Issuer 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 (iii) the Issuer 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.

 

(t) The
Class A Shares are eligible for clearing through The Depository Trust Company (the “DTC”), through its Deposit/Withdrawal
At Custodian (DWAC) system, and the Issuer is eligible and participating in the Direct Registration System (DRS) of DTC with respect
to the Class A Shares. The Transfer Agent is a participant in DTC’s Fast Automated Securities Transfer Program.

 

(u) The
Issuer acknowledges that there have been no, and in issuing the Acquired Shares the Issuer is not relying on any, representations,
warranties, covenants and agreements made to the Issuer by Subscriber, any of its officers, directors or representatives or any
other person or entity, expressly or by implication, other than those representations, warranties, covenants and agreements expressly
stated in this Subscription Agreement.

 

(v) Following
the Closing, the Acquired Shares will not be subject to any Transfer Restriction. The term “Transfer Restriction”
means any condition to or restriction on the ability of Subscriber to pledge, sell, assign or otherwise transfer the Acquired
Shares under any organizational document or agreement of, by or with the Issuer, but excluding the restrictions on transfer described
in Section 4(f) hereof with respect to the status of the Acquired Shares as “restricted securities” pending
their registration for resale under the Securities Act in accordance with the terms of this Subscription Agreement or the Registration
Rights Agreement.

 

4. Subscriber
Representations and Warranties. Subscriber represents and warrants that:

 

(a) If
Subscriber is not an individual, Subscriber has been duly formed or incorporated and is validly existing and in good standing
under the laws of its jurisdiction of incorporation or formation, with power and authority to enter into, deliver and perform
its obligations under this Subscription Agreement. If Subscriber is an individual, Subscriber has the authority to enter into,
deliver and perform its obligations under this Subscription Agreement.

 

(b) This
Subscription Agreement has been duly authorized, executed and delivered by Subscriber and, assuming that this Subscription Agreement
has been duly authorized, executed and delivered by the Issuer, this Subscription Agreement is the valid and binding obligation
of Subscriber, enforceable against Subscriber in accordance with its terms, except as may be limited or otherwise affected by
(i) bankruptcy, insolvency, reorganization, fraudulent conveyance, moratorium or other laws relating to or affecting the
rights of creditors generally, and (ii) principles of equity, whether considered at law or equity.

 

    8

     

    

 

(c) The
execution, delivery and performance by Subscriber of this Subscription Agreement, including the consummation of the transactions

Subscription Agreement, and that neither the Issuer nor Target nor any of their respective affiliates, have provided any tax advice
or any other representation or guarantee, whether written or oral, regarding the tax consequences of the transactions contemplated
by this Subscription Agreement.

 

(d) The
execution, delivery and performance by Subscriber of this Subscription Agreement, including the consummation of the transactions
contemplated hereby 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 or any of its subsidiaries pursuant to the terms of (i) any indenture, mortgage, deed of trust, loan agreement,
lease, license or other agreement or instrument to which Subscriber or any of its subsidiaries is a party or by which Subscriber
or any of its subsidiaries is bound or to which any of the property or assets of Subscriber or any of its subsidiaries is subject;
(ii) Subscriber’s organizational documents or under any law, rule, regulation, agreement or other obligation by which Subscriber

case of clauses (i) and (iii), would reasonably be expected to have a material adverse effect on the legal authority or ability
of Subscriber to perform in any material respects its obligations hereunder.

 

(e) 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) under the Securities Act) satisfying the applicable requirements
set forth on Schedule A, (ii) is acquiring the Acquired Shares only for its own account and not for the account of
others, or if Subscriber is a “qualified institutional buyer” and is subscribing for the Acquired Shares as a fiduciary
or agent for one or more investor accounts, each owner of such account is a “qualified institutional buyer” 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 Acquired
Shares with a view to, or for offer or sale in connection with, any distribution thereof in violation of the Securities Act or
any other securities laws of the United States or any other jurisdiction (and shall provide the requested information on Schedule
A following the signature page hereto). Subscriber is not an entity formed for the specific purpose of acquiring the Acquired
Shares, unless such newly formed entity is an entity in which all of the equity owners are “accredited investors”
(within the meaning of Rule 501(a) under the Securities Act).

 

(f) Subscriber
understands that the Acquired Shares are being offered in a transaction not involving any public offering within the meaning of
the Securities Act and that the Acquired Shares have not been registered under the Securities Act or any other securities laws
of the United States or any other jurisdiction. Subscriber understands that it is acquiring its entire beneficial ownership interest
in the Acquired Shares for Subscriber’s own account for investment purposes only and not with a view to any distribution
of the Acquired Shares in any manner that would violate the securities laws of the United States or any other jurisdiction. Subscriber
understands that the Acquired Shares may not be resold, transferred, pledged or otherwise disposed of by Subscriber absent an
effective registration statement under the Securities Act, except (i) to the Issuer or a subsidiary thereof, (ii) pursuant to
offers and sales that occur in an “offshore transaction” within the meaning of Regulation S under the Securities Act,
(iii) pursuant to Rule 144 under the Securities Act, provided that all of the applicable conditions thereof (including those set
out in Rule 144(i) which are applicable to the Issuer) have been met, or (iv) pursuant to another applicable exemption from the
registration requirements of the Securities Act, including pursuant to a private sale effected under Section 4(a)(7) of the Securities
Act or applicable formal or informal Commission interpretation or guidance, such as a so-called “4(a)(1) and a half”
sale, and that any certificates or book-entry records representing the Acquired Shares shall contain a legend to such effect,
which legend shall be subject to removal as set forth herein and in the Amended and Restated Registration Rights Agreement, dated
the date hereof, by and among the Issuer and other parties thereto (the “Registration Rights Agreement”) to
the extent that Subscriber is party to the Registration Rights Agreement, in which case, notwithstanding anything else contained
herein to the contrary, Section 5 and 8(c) hereof shall not apply and not be effective with respect to such Subscriber. Subscriber
understands and agrees that the Acquired Shares will be subject to the foregoing restrictions and, as a result, Subscriber may
not be able to readily resell the Acquired Shares and may be required to bear the financial risk of an investment in the Acquired
Shares for an indefinite period of time. Subscriber understands that it has been advised to consult legal counsel prior to making
any offer, resale, pledge or transfer of any of the Acquired Shares. By making the representations herein, Subscriber does not
agree to hold any of the Acquired Shares for any minimum or other specific term and reserves the right to assign, transfer or
otherwise dispose of any of the Acquired Shares at any time in accordance with or pursuant to a registration statement or an exemption
under the Securities Act.

(g) Subscriber
understands and agrees that Subscriber is purchasing the Acquired Shares directly from the Issuer. Subscriber further acknowledges
that there have been no, and in purchasing the Acquired Shares Subscriber is not relying on any, representations, warranties,
covenants and agreements made to Subscriber by the Issuer, any of its officers, directors or representatives or any other person
or entity, expressly or by implication, other than those representations, warranties, covenants and agreements expressly stated
in this Subscription Agreement.

 

(h) To
the extent applicable to it, Subscriber represents and warrants that its acquisition and holding of the Acquired Shares will not
constitute or result in a non-exempt prohibited transaction under section 406 of the Employee Retirement Income Security Act of
1974, as amended, section 4975 of the Internal Revenue Code of 1986, as amended (the “Code”), or any applicable
similar law.

 

(i) In
making its decision to purchase the Acquired Shares, Subscriber represents that it has conducted and completed its own independent
due diligence and has independently made its own analysis and decision with respect to the Subscription. Subscriber further represents
that, except for the representations, warranties, covenants and agreements made by Issuer herein, it is relying exclusively on
its own sources of information, investment analysis and due diligence (including professional advice Subscriber deems appropriate)
with respect to the Subscription, the Acquired Shares and the business, condition (financial and otherwise), management, operations,
properties and prospects of the Issuer, including but not limited to all business, legal, regulatory, accounting, credit and tax
matters. Subscriber acknowledges and agrees that it has received, reviewed and understood the offering materials made available
to it in connection with the Subscription and such other information as Subscriber deems necessary in order to make an investment
decision with respect to the Acquired Shares, including with respect to the Issuer, Target 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 from the Issuer directly as Subscriber and such Subscriber’s professional
advisor(s), if any, have deemed necessary to make an investment decision with respect to the Acquired Shares. However, neither
any such inquiries, nor any due diligence investigation conducted by Subscriber or any of Subscriber’s professional advisors
nor anything else contained herein, shall modify, limit or otherwise affect Subscriber’s right to rely on the Issuer’s
representations, warranties, covenants and agreements contained in this Subscription Agreement. Subscriber acknowledges that it
is not relying upon, and has not relied upon, any statement, representation or warranty made by any person, firm or corporation
(including, without limitation, the Issuer, Target, the Placement Agent, any of their respective affiliates or any control persons,
officers, directors, employees, agents or representatives of any of the foregoing), other than the representations and warranties
of the Issuer contained in Section 3 of this Subscription Agreement, in making its investment or decision to invest in
the Issuer.

 

    10

     

    

 

(j) Subscriber
became aware of this offering of the Acquired Shares solely by means of direct contact between Subscriber and the Issuer or by
means of contact from Jefferies LLC acting as placement agent for the Issuer (the “Placement Agent”), and the
Acquired Shares were offered to Subscriber solely by direct contact between Subscriber and the Issuer or by contact between Subscriber
and one or more Placement Agent. Subscriber did not become aware of this offering of the Acquired Shares, nor were the Acquired
Shares offered to Subscriber, by any other means.

 

(k) Subscriber
acknowledges and agrees that the Placement Agent is acting solely as the placement agent in connection with the Subscription and
is not acting as underwriters or in any other capacity and is not and shall not be construed as a fiduciary for Subscriber, the
Issuer or any other person or entity in connection with the Subscription.

 

(l) Subscriber
acknowledges that it is aware that there are substantial risks incident to the purchase and ownership of the Acquired Shares,
including those set forth in the SEC Reports. Subscriber has such knowledge and experience in financial, business and private
equity matters as to be capable of evaluating the merits and risks of an investment, both in general and with regard to transactions
and investment strategies involving a security or securities, including Subscriber’s investment in the Acquired Shares,
and Subscriber has sought such accounting, legal and tax advice as Subscriber has considered necessary to make an informed investment
decision.

 

(m) Subscriber
represents and acknowledges that, alone, or together with any professional advisor(s), Subscriber has adequately analyzed and
fully considered the risks of an investment in the Acquired Shares and determined that the Acquired 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 Issuer. Subscriber acknowledges specifically that a possibility of total loss exists.

 

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

 

(o) Subscriber
represents and warrants that Subscriber is not (i) a person or entity named on the List of Specially Designated Nationals
and Blocked Persons, the Executive Order 13599 List, the Foreign Sanctions Evaders List, or the Sectoral Sanctions Identification
List, each of which is administered by the U.S. Treasury Department’s Office of Foreign Assets Control (“OFAC”)
(collectively, “OFAC Lists”) (ii) owned or controlled by, or acting on behalf of, a person, that is named on
an OFAC List; (iii) organized, incorporated, established, located, resident or born in, or a citizen, national, or the government,
including any political subdivision, agency, or instrumentality thereof, of, Cuba, Iran, North Korea, Syria, the Crimea region
of Ukraine, or any other country or territory embargoed or subject to substantial trade restrictions by the United States, (iv) a
Designated National as defined in the Cuban Assets Control Regulations, 31 C.F.R. Part 515, or (v) a non-U.S. shell bank
or providing banking services indirectly to a non-U.S. shell bank. Subscriber agrees to provide law enforcement agencies, if requested
thereby, such records as required by applicable law, provided that Subscriber is permitted to do so under applicable law. Subscriber
represents that if it is a financial institution subject to the Bank Secrecy Act (31 U.S.C. section 5311 et seq.) (the “BSA”),
as amended by the USA PATRIOT Act of 2001 (the “PATRIOT Act”), 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, to the extent required, it maintains policies and procedures
reasonably designed to ensure compliance with OFAC-administered sanctions programs, including for the screening of its investors
against the OFAC Lists. Subscriber further represents and warrants that, to the extent required, it maintains policies and procedures
reasonably designed to ensure that the funds held by Subscriber and used to purchase the Acquired Shares were legally derived.

 

    11

     

    

 

(p) If
Subscriber is or is acting on behalf of (i) an employee benefit plan that is subject to Title I of the Employee Retirement Income
Security Act of 1974, as amended (“ERISA”), (ii) a plan, an individual retirement account or other arrangement
that is subject to Section 4975 of the Code, (iii) an entity whose underlying assets are considered to include "plan assets"
of any such plan, account or arrangement described in clauses (i) and (ii) (each, an "ERISA Plan"), or (iv) 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
clauses (i), (ii) or (iii) 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 (collectively, "Similar Laws," and together with ERISA
Plans, "Plans"), then Subscriber represents and warrants that it has not relied on the Issuer or any of its affiliates
(the ”Transaction Parties”) for investment advice or as the Plan’s fiduciary with respect to its decision
to acquire and hold the Acquired Shares, and none of the Transaction Parties is or shall at any time be relied upon as the Plan’s
fiduciary with respect to any decision to acquire and hold or transfer the Acquired Shares; and (B) its purchase of the Shares
will not result in a non-exempt prohibited transaction under Section 406 of ERISA or Section 4975 of the Code, or any applicable
Similar Law.

 

(q) At
the Purchase Price Payment Date, Subscriber will have sufficient funds to pay the Purchase Price pursuant to Section 2(a).

 

5. Registration
Rights.

 

(a) The
Issuer agrees that, as soon as practicable, but in no event later than thirty (30) calendar days after the Closing Date (the “Filing
Date”), the Issuer will file with the Commission (at the Issuer’s sole cost and expense) a registration statement
registering the resale of the Acquired Shares (the “Registration Statement”), and the Issuer shall use its
commercially reasonable efforts to cause the Registration Statement to be declared effective as soon as practicable after the
filing thereof, but no later than the earlier of (i) the 60th calendar day (or 100th calendar day if the
Commission notifies the Issuer that it will “review” the Registration Statement) following the Closing and (ii) the
10th business day after the date the Issuer 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 (such earlier date,
the “Effectiveness Date”); provided, however, that if the Commission is closed for operations due to
a government shutdown, the Effectiveness Date shall be extended by the same amount of days that the Commission remains closed
for operations, provided, further, that the Issuer’s obligations to include the Acquired Shares in the Registration
Statement are contingent upon Subscriber furnishing in writing to the Issuer such information regarding Subscriber, the securities
of the Issuer held by Subscriber, the intended method of disposition of the Acquired Shares (which shall be limited to non-underwritten
public offerings) and such other information as shall be reasonably requested by the Issuer to effect the registration of the
Acquired Shares, and Subscriber shall execute such documents in connection with such registration as the Issuer may reasonably
request that are customary of a selling stockholder in similar situations, including providing that the Issuer shall be entitled
to postpone and suspend the effectiveness or use of the Registration Statement during any customary blackout or similar period
or as permitted hereunder; provided, however, under no circumstances shall Subscriber be required to sign any type of lock-up
agreement. Any failure by the Issuer to file the Registration Statement by the Filing Date or to effect such Registration Statement
by the Effectiveness Date shall not otherwise relieve the Issuer of its obligations to file or effect the Registration Statement
as set forth above in this Section 5. The Issuer will provide a draft of the Registration Statement to the undersigned
for review at least two (2) business days in advance of filing the Registration Statement. In no event shall the undersigned be
identified as a statutory underwriter in the Registration Statement unless requested by the Commission; provided, that, if the
Commission requests that the undersigned be identified as a statutory underwriter in the Registration Statement, the undersigned
will have an opportunity to withdraw its Acquired Shares from the Registration Statement. Notwithstanding the foregoing, if the
Commission prevents the Issuer 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 Acquired Shares by the applicable stockholders
or otherwise, such Registration Statement shall register for resale such number of Acquired Shares which is equal to the maximum
number of Acquired Shares as is permitted by the Commission. In such event, the number of Acquired Shares to be registered for
each selling shareholder named in the Registration Statement shall be reduced pro rata among all such selling shareholders. In
the event the Issuer amends the Registration Statement in accordance with the foregoing, the Issuer will use its commercially
reasonable efforts to file with the Commission, as promptly as allowed by the Commission, one or more registration statements
to register the resale of those Registrable Securities (as defined below) that were not registered on the initial Registration
Statement, as so amended. The Issuer will use its commercially reasonable efforts to maintain the continuous effectiveness of
the Registration Statement until all such securities cease to be Registrable Securities (as defined below) or such shorter period
upon which each undersigned party with Registrable Securities included in such Registration Statement have notified the Issuer
that such Registrable Securities have actually been sold. The Issuer will provide all customary and commercially reasonable cooperation
necessary to enable the undersigned to resell Registrable Securities pursuant to the Registration Statement or Rule 144 under
the Securities Act (“Rule 144”), as applicable, qualify the Registrable Securities for listing on the primary
stock exchange on which its Class A Shares are then listed, update or amend the Registration Statement as necessary to include
Registrable Securities and provide customary notice to holders of Registrable Securities. “Registrable Securities”
shall mean, as of any date of determination, the Acquired Shares and any other equity security of the Issuer issued or issuable
with respect to the Acquired Shares by way of share split, dividend, distribution, recapitalization, merger, exchange, replacement
or similar event or otherwise. As to any particular Registrable Securities, once issued, such securities shall cease to be Registrable
Securities at the earliest of: (A) when the undersigned ceases to hold any Registrable Securities; (B) the date all Registrable
Securities held by the undersigned may be sold without restriction under Rule 144, including without limitation, any volume and
manner of sale restrictions which may be applicable to affiliates under Rule 144, and without the requirement for the Issuer to
be in compliance with the current public information required under Rule 144 or (C) when they shall have ceased to be outstanding
or three (3) years from the date of effectiveness of the Registration Statement.

 

    12

     

    

 

(b) In
the case of the registration, qualification, exemption or compliance effected by the Issuer pursuant to this Subscription Agreement,
the Issuer shall, upon reasonable request, inform Subscriber as to the status of such registration, qualification, exemption and
compliance. At its expense the Issuer shall:

 

(i) except
for such times as the Issuer is permitted hereunder to suspend the use of the prospectus forming part of a Registration Statement,
use its commercially reasonable efforts to keep such registration, and any qualification, exemption or compliance under state
securities laws which the Issuer determines to obtain, continuously effective with respect to Subscriber, and to keep the applicable
Registration Statement or any subsequent shelf registration statement free of any material misstatements or omissions, for as
long as Subscriber continues to hold Registrable Securities;

  

(ii) advise
Subscriber, as promptly as practicable but in any event, within three (3) business days:

 

(1) 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;

 

(2) 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;

 

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

 

(4) 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 included therein 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 (and 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 Issuer shall not, when so advising Subscriber of such events, provide Subscriber
with any material, nonpublic information regarding the Issuer other than to the extent that providing notice to Subscriber of
the occurrence of the events listed in (1) through (4) above may constitute material, nonpublic information regarding the
Issuer;

 

(iii) use
its commercially reasonable efforts to obtain the withdrawal of any order suspending the effectiveness of any Registration Statement
as soon as reasonably practicable;

 

(iv) upon
the occurrence of any event contemplated in Section 5(b)(ii)(4), except for such times as the Issuer is permitted hereunder
to suspend, and has suspended, the use of a prospectus forming part of a Registration Statement, the Issuer 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
Acquired 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;

 

(v) use
its commercially reasonable efforts to cause all Acquired Shares to be listed on the primary securities exchange or market, if
any, on which the Class A Shares issued by the Issuer have been listed;

 

(vi) allow
Subscriber to review and consent to disclosure specifically regarding Subscriber in the Registration Statement on reasonable advance
notice (which consent shall not be unreasonably withheld); and

 

(vii) use
its commercially reasonable efforts to take all other steps reasonably necessary to effect the registration of the Acquired Shares
contemplated hereby and, for so long as Subscriber holds Acquired Shares, to enable Subscriber to sell the Acquired Shares under
Rule 144.

 

    13

     

    

 

(c) Notwithstanding
anything to the contrary in this Subscription Agreement, the Issuer shall be entitled to delay the filing or postpone the effectiveness
of the Registration Statement, and from time to time to require Subscriber not to sell under the Registration Statement or to
suspend the effectiveness thereof, if the negotiation or consummation of a transaction by the Issuer or its subsidiaries is pending
or an event has occurred, which negotiation, consummation or event, the Issuer’s board of directors reasonably believes
would require additional disclosure by the Issuer in the Registration Statement of material information that the Issuer 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 Issuer’s board of directors would be expected to cause the Registration Statement
to fail to comply with applicable disclosure requirements (each such circumstance, a “Suspension Event”); provided,
however, that the Issuer may not delay or suspend the Registration Statement on more than two occasions or for more than
forty five (45) consecutive calendar days, or more than ninety (90) total calendar days, in each case during any twelve
(12)-month period. Upon receipt of any written notice from the Issuer of the happening 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 Acquired 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 Issuer 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
Issuer 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 Issuer unless otherwise required by law or subpoena. If so directed by the Issuer, Subscriber
will deliver to the Issuer or, in Subscriber’s sole discretion destroy, all copies of the prospectus covering the Acquired
Shares in Subscriber’s possession; provided, however, that this obligation to deliver or destroy all copies of the
prospectus covering the Acquired Shares shall not apply (i) 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 (ii) to copies stored electronically on archival servers
as a result of automatic data back-up.

 

(d) Subscriber
may deliver written notice (an “Opt-Out Notice”) to the Issuer requesting that Subscriber not receive notices
from the Issuer otherwise required by this Section 5; provided, however, that Subscriber may later revoke
any such Opt-Out Notice in writing. Following receipt of an Opt-Out Notice from Subscriber (unless subsequently revoked), (i)
the Issuer shall not deliver any such notices to Subscriber and Subscriber shall no longer be entitled to the rights associated
with any such notice and (ii) each time prior to Subscriber’s intended use of an effective Registration Statement, Subscriber
will notify the Issuer in writing at least two (2) business days in advance of such intended use, and if a notice of a Suspension
Event was previously delivered (or would have been delivered but for the provisions of this Section 5(d)) and the related
suspension period remains in effect, the Issuer will so notify Subscriber, within one (1) business day of Subscriber’s notification
to the Issuer, by delivering to Subscriber a copy of such previous notice of Suspension Event, and thereafter will provide Subscriber
with the related notice of the conclusion of such Suspension Event promptly following its availability.

 

    14

     

    

 

(e) Indemnification.

 

(i) The
Issuer shall, notwithstanding the termination of this Subscription Agreement, indemnify and hold harmless, to the extent permitted
by law, Subscriber, its directors, officers, employees, agents, trustees, partners, members, managers, stockholders, investment
advisors and sub-advisors, 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 the Securities Act or the Exchange Act) from and against any and all losses,
claims, damages, liabilities, costs and expenses (including, without limitation, any reasonable attorneys’ fees and expenses
incurred in connection with defending or investigating any such action or claim) (collectively, “Losses”) that
arise out of or are caused by (A) any untrue or alleged untrue statement of material fact contained in any Registration Statement
(or incorporated by reference therein), prospectus included in any Registration Statement (“Prospectus”) or
preliminary Prospectus or any amendment thereof or supplement thereto or document incorporated by reference therein or any omission
or alleged omission of a material fact required to be stated therein or necessary to make the statements therein in light of the
circumstances under which they were made, not misleading insofar as the same are caused by or contained in any information furnished
in writing to the Issuer by or on behalf of such Subscriber expressly for use therein. The Issuer shall notify Subscriber promptly
of the institution, threat or assertion (to the Issuer’s knowledge) of any proceeding arising from or in connection with
the Transactions; provided, however, that the indemnification contained in this Section 5(e) shall not apply
to amounts paid in settlement of any Losses if such settlement is effected without the consent of the Issuer (which consent shall
not be unreasonably withheld, conditioned or delayed), nor shall the Issuer be liable for any Losses to the extent they arise
out of or are based upon a violation which occurs (A) in connection with any failure of such person to deliver or cause to be
delivered a Prospectus made available by the Issuer in a timely manner or (B) in connection with any offers or sales effected
by or on behalf of Subscriber in violation of this Agreement.

 

(ii) In
connection with any Registration Statement in which Subscriber is participating, Subscriber shall furnish to the Issuer in writing
such information as the Issuer reasonably requests for use in connection with any such Registration Statement or Prospectus. In
connection with any Registration Statement in which Subscriber is participating, Subscriber agrees, severally and not jointly
with any Other Subscriber or other investor that is a party to the Other Subscription Agreements, to indemnify and hold harmless,
to the extent permitted by law, the Issuer, its directors and officers and agents and employees and each person or entity who
controls the Issuer (within the meaning of Section 15 of the Securities Act) against any Losses, resulting from or arising out
of any untrue or alleged untrue statement of material fact contained in the Registration Statement, Prospectus 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 in light of the circumstances under which they were made, not misleading,
but only to the extent that such untrue statement or omission is contained (or not contained in the case of an omission) in and
are based on any information or affidavit so furnished in writing by or on behalf of Subscriber expressly for use therein; provided,
however, that in no event shall the liability of Subscriber be greater in amount than the dollar amount of the net proceeds
received by Subscriber from the sale of Acquired Shares pursuant to such Registration Statement giving rise to such indemnification
obligation.

 

(iii) Any
person entitled to indemnification herein shall (1) 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 prejudiced the indemnifying party) and (2) 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.
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.

 

    15

     

    

 

(iv) The
indemnification provided 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 Acquired Shares.

 

(v) If
the indemnification provided under this Section 5(e) from the indemnifying party is unavailable or insufficient to hold
harmless an indemnified party in respect of any Losses referred to herein, then the indemnifying party, in lieu of indemnifying
the indemnified party, shall contribute to the amount paid or payable by the indemnified party as a result of such Losses 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 not made by, in the case of an omission), or relates
to information supplied by (or not supplied by, in the case of an omission), 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 in Sections 5(e)(i), 5(e)(ii), 5(e)(iii),
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 5(e)(v) from any person who was not guilty of such fraudulent misrepresentation.

 

6. Termination.
This Subscription Agreement shall terminate and be void and of no further force and effect (except for those provisions expressly
contemplated to survive termination of this Subscription Agreement), and all rights and obligations of the parties hereunder shall
terminate without any further liability on the part of any party in respect thereof (except with respect to those provisions expressly
contemplated to survive termination of this Subscription Agreement), upon the earlier to occur of (a) such date and time
as the Business Combination Agreement is terminated in accordance with its terms, (b) upon the mutual written agreement of
each of the 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 earlier of the Closing Date or November
9, 2021 (the “Outside Date”), or become incapable of being satisfied on or prior to the earlier of the Closing
Date or the Outside Date, and, as a result thereof, the transactions contemplated by this Subscription Agreement are not consummated
at the Closing, or (d) the Outside Date; provided, that nothing herein will relieve any party from liability for any willful
breach hereof prior to the time of termination, and each party will be entitled to any remedies at law or in equity to recover
Losses, liabilities or damages arising from such breach. The Issuer shall promptly notify Subscriber in writing (with email being
sufficient) of the termination of the Business Combination Agreement. Upon the termination hereof, any monies paid by Subscriber
to the Issuer in connection herewith shall promptly (and in any event within one (1) business day) be returned in full to Subscriber
by wire transfer of U.S. dollars in immediately available funds to the account specified by Subscriber, without any deduction
for or on account of any tax withholding, charges or set-off, whether or not the Transactions shall have been consummated.

7. Additional
Agreements and Waivers of Subscriber.

 

(a) Trust
Account Waiver. Subscriber acknowledges that the Issuer is a blank check company with the powers and privileges to effect
a merger, asset acquisition, reorganization or similar business combination involving the Issuer and one or more businesses or
assets. Subscriber further acknowledges that, as described in the Issuer’s prospectus relating to its initial public offering
dated September 1, 2020 (the “September 1, 2020 Prospectus”), available at sec.gov, substantially all of the
Issuer’s assets consist of the cash proceeds of the Issuer’s initial public offering and private placements of its
securities, and substantially all of those proceeds have been deposited in a trust account (the “Trust Account”)
for the benefit of its public stockholders and the underwriters of its initial public offering. The cash in the Trust Account
may be disbursed only for the purposes set forth in the September 1, 2020 Prospectus. For and in consideration of the Issuer entering
into this Subscription Agreement, the receipt and sufficiency of which are hereby acknowledged, Subscriber hereby irrevocably
waives any and all right, title and interest, or any claim of any kind they have or may have in the future as a result of, or
arising out of, this Subscription Agreement, in or to any monies held in the Trust Account, and agrees not to seek recourse or
make or bring any action, suit, claim or other proceeding against the Trust Account as a result of, or arising out of, this Subscription
Agreement, the transactions contemplated hereby or the Acquired Shares, regardless of whether such claim arises based on contract,
tort, equity or any other theory of legal liability; provided however, that nothing in this Section 5 shall be deemed
to limit any Subscriber’s right, title, interest or claim to the Trust Account by virtue of such Subscriber’s record
or beneficial ownership of securities of the Issuer acquired by any means other than pursuant to this Subscription Agreement,
including but not limited to any redemption right with respect to any such securities of the Issuer. Subscriber acknowledges and
agrees that it shall not have any redemption rights with respect to the Acquired Shares pursuant to the Issuer’s certificate
of incorporation in connection with the Transactions or any other business combination, any subsequent liquidation of the Trust
Account or the Issuer or otherwise. In the event Subscriber has any claim against the Issuer as a result of, or arising out of,
this Subscription Agreement, the transactions contemplated hereby or the Acquired Shares, it shall pursue such claim solely against
the Issuer and its assets outside the Trust Account and not against the Trust Account or any monies or other assets in the Trust
Account. This paragraph shall survive any termination of this Subscription Agreement.

 

(b) No
Hedging. Subscriber hereby agrees that neither it, nor any person or entity acting on its behalf or pursuant to any understanding
with it, shall execute any short sales (as such term is defined in Regulation SHO under the Exchange Act, 17 CFR 242.200) or engage
in other hedging transactions of any kind with respect to the Acquired Shares during the period from the date of this Subscription
Agreement through the Closing (or such earlier termination of this Subscription Agreement). Notwithstanding anything to the contrary
set forth herein, (i) nothing in this Section 7(b) shall prohibit any entities under common management or that share an
investment advisor with the Subscriber that have no knowledge of this Subscription Agreement or of Subscriber’s participation
in this transaction (including Subscriber’s controlled affiliates and/or affiliates) from entering into any short sales
or engaging in other hedging transactions; and (ii) 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
7(b) shall only apply with respect to the portion of assets managed by the portfolio manager that made the investment decision
to purchase the Subscription Amount covered by this Subscription Agreement. The Issuer acknowledges and agrees that, notwithstanding
anything herein to the contrary, the Acquired Shares may be pledged by Subscriber in connection with a bona fide margin agreement,
provided that such pledge shall be (i) pursuant to an available exemption from the registration requirements of the Securities
Act or (ii) pursuant to, and in accordance with, a registration statement that is effective under the Securities Act at the time
of such pledge, and Subscriber effecting a pledge of the Acquired Shares shall not be required to provide the Issuer with any
notice thereof; provided, however, that neither the Issuer nor its counsel shall be required to take any action (or refrain from
taking any action) in connection with any such pledge, other than providing any such lender of such margin agreement with an acknowledgment
that the Acquired Shares are not subject to any contractual lock up or prohibition on pledging, the form of such acknowledgment
to be subject to review and comment by the Issuer in all respects.

8. Issuer’s
Covenants.

 

(a) Except
as contemplated herein, the Issuer, its subsidiaries and their respective affiliates shall not, and shall cause any person acting
on behalf of any of the foregoing to not, take any action or steps that would require registration of the issuance of any of the
Acquired Shares under the Securities Act.

 

(b) With
a view to making available to Subscriber the benefits of Rule 144 or any other similar rule or regulation of the Commission that
may at any time permit Subscriber to sell securities of the Issuer to the public without registration, the Issuer agrees, for
so long as Subscriber holds Registrable Securities to:

 

(i) make
and keep public information available, as those terms are understood and defined in Rule 144;

 

(ii) file
with the Commission in a timely manner all reports and other documents required of the Issuer under the Securities Act and the
Exchange Act so long as the Issuer remains subject to such requirements and the filing of such reports and other documents is
required for the applicable provisions of Rule 144; and

 

(iii) furnish
to Subscriber so long as it owns Acquired Shares, promptly upon request, (x) a written statement by the Issuer, if true, that
it has complied with the reporting requirements of Rule 144, the Securities Act and the Exchange Act, (y) a copy of the most recent
annual or quarterly report of the Issuer and such other reports and documents so filed by the Issuer (public availability on the
Commission’s EDGAR system (or successor system) being sufficient) and (z) such other information as may be reasonably requested
to permit Subscriber to sell such securities pursuant to Rule 144 without registration.

 

(c) The
Issuer shall use its commercially reasonable efforts to remove the legend described in Section 4(f) and to issue a certificate
or a book entry record without such legend to the holder of the Acquired Shares upon which it is stamped or issue to such holder
by electronic delivery at the applicable balance account at The Depository Trust Company (“DTC”), if (i) such
Acquired Shares are registered for resale under the Securities Act, upon the sale thereof, if such holder provides customary paperwork
in a form reasonably acceptable to the Issuer to the effect that it has sold such securities pursuant to an effective registration
statement under the Securities Act and the plan of distribution set forth therein, provided that the Issuer shall use its commercially
reasonable efforts to cause its legal counsel to deliver the necessary legal opinions, if any, to the transfer agent in connection
therewith, (ii) in connection with a sale, assignment or other transfer, such holder provides the Issuer with an opinion of counsel
and other customary paperwork, in a form reasonably acceptable to the Issuer, to the effect that such sale, assignment or transfer
of the Acquired Shares may be made without registration under the applicable requirements of the Securities Act and such holder
agrees to sell, assign or otherwise transfer such securities in accordance with such valid exemption from the registration requirements
of the Securities Act, or (iii) the Acquired Shares can be sold, assigned or transferred without restriction or current public
information requirements pursuant to Rule 144, including without limitation, any volume and manner of sale restrictions which
may be applicable to affiliates under Rule 144 and any requirement for the Issuer to be in compliance with the current public
information required under Rule 144(c) or Rule 144(i), as applicable, and in each case, the holder provides the Issuer with customary
paperwork including an undertaking to effect that any sales or other transfers will occur in accordance with Rule 144. The Issuer
shall be responsible for the fees of the Transfer Agent and all DTC fees associated with such issuance and Subscriber shall be
responsible for all other fees and expenses (including, without limitation, any applicable broker fees, fees and disbursements
of their legal counsel and any applicable transfer taxes).

 

    18

     

    

 

9. Miscellaneous.

 

(a) Each
party hereto acknowledges that the other party hereto will rely on the acknowledgments, understandings, agreements, representations
and warranties contained in this Subscription Agreement. Prior to the Closing, each party hereto agrees to promptly notify the

Agent is a third-party beneficiary of the representations and warranties of the Subscriber contained in this Subscription Agreement.

 

(b) Each
of the Issuer and Subscriber is entitled to rely upon this Subscription Agreement and is irrevocably authorized to produce this

Agreement.

 

(c) This

advisor as Subscriber or by an affiliate of such investment manager or investor advisor, without the prior consent of the Issuer,
provided that such assignee(s) agrees in writing to be bound by the terms hereof. Upon such assignment by a Subscriber,
the assignee(s) shall become Subscriber hereunder and have the rights and obligations provided for herein to the extent of such
assignment; provided further that, no assignment shall relieve the assigning party of any of its obligations hereunder,
including any assignment to any fund or account managed by the same investment manager or investment advisor as Subscriber or
by an affiliate of such investment manager or investment advisor, unless consented to in writing by the Issuer (such consent not
to be unreasonably conditioned, delayed or withheld).

 

(d) All
the representations and warranties made by each party hereto in this Subscription Agreement shall survive the Closing. All covenants
made by each party hereto in this Subscription Agreement required to be performed after the Closing shall expire upon performance.

 

(e) The
Issuer may request from Subscriber such additional information as the Issuer may deem reasonably necessary to evaluate the eligibility
of Subscriber to acquire the Acquired Shares, and Subscriber shall provide such information as may be reasonably requested, to
the extent readily available and to the extent consistent with its internal policies and procedures; provided, that, the Issuer
agrees to keep any such information provided by Subscriber confidential; provided, further, that upon recipient of such additional
information, the Issuer shall be allowed to convey such information to the Placement Agent and such Placement Agent shall have
agreed to keep the information confidential (with Subscriber being any express third party beneficiary of such agreement), except
as may be required by applicable law, rule, regulation or in connection with any legal proceeding or regulatory request.

 

(f) This
Subscription Agreement may not be amended, modified, waived or terminated except by an instrument in writing, signed by each of
the parties hereto. This Subscription Agreement may not be waived except by an instrument in writing, signed by the party against
whom enforcement of such waiver is sought.

 

    19

     

    

 

(g) This
Subscription Agreement (including the schedule hereto) 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.

 

(h) Except
as otherwise provided herein, this Subscription Agreement shall be binding upon, and inure to the benefit of the parties hereto
and their heirs, executors, administrators, successors, legal representatives, and permitted assigns, and the agreements, representations,
warranties, covenants and acknowledgments contained herein shall be deemed to be made by, and be binding upon, such heirs, executors,
administrators, successors, legal representatives and permitted assigns.

 

(i) 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.

 

(j) This
Subscription Agreement may be executed in two (2) or more counterparts (including by electronic means), all of which shall
be considered one and the same agreement and shall become effective when signed by each of the parties and delivered to the other
parties, it being understood that all parties need not sign the same counterpart.

 

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

 

(l) The
Issuer shall be solely responsible for the fees of the Placement Agent, Transfer Agent, the escrow agent, stamp taxes and all
of DTC’s fees associated with the issuance of the Acquired Shares.

 

(m) Subscriber
understands and agrees that (i) no disclosure or offering document has been prepared by the Placement Agent or any of its respective
affiliates in connection with the offer and sale of the Acquired Shares; (ii) the Placement Agent and its respective directors,
officers, employees, representatives and controlling persons has made no independent investigation with respect to the Issuer,
Target, the Transactions or the Acquired Shares or the accuracy, completeness or adequacy of any information supplied to Subscriber
by the Issuer; and (iii) in connection with the issue and purchase of the Acquired Shares, the Placement Agent has not acted as
the Subscriber’s financial advisor, tax or fiduciary.

 

(n) Any
notice or communication required or permitted hereunder shall be in writing and either delivered personally, emailed or telecopied,
sent by overnight mail via a reputable overnight carrier, or sent by certified or registered mail, postage prepaid, and shall
be deemed to be given and received (i) when so delivered personally, (ii) upon receipt of an appropriate electronic
answerback or confirmation when so delivered by telecopy (to such number specified below or another number or numbers as such
person may subsequently designate by notice given hereunder), (iii) when sent, with no mail undeliverable or other rejection notice,
if sent by email, or (iv) five (5) business days after the date of mailing to the address below or to such other address

Agreement, 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 Transactions
and any other material, nonpublic information that the Issuer has provided to Subscriber any time prior to the filing of the Disclosure
Document. Upon the issuance of the Disclosure Document, to the Issuer’s knowledge, Subscriber shall not be in possession
of any material, non-public information received from the Issuer or any of its officers, directors or employees or agents (including
the Placement Agent) and Subscriber shall no longer be subject to any confidentiality or similar obligations under any current
agreement, whether written or oral with the Issuer, the Placement Agent or any of its affiliates. Notwithstanding anything in
this Subscription Agreement to the contrary, the Issuer shall not publicly disclose the name of Subscriber or any of its affiliates
or its investment adviser, or include the name of Subscriber or any of its affiliates or its investment adviser without the prior
written consent of Subscriber (i) in any press release or (ii) in any filing with the Commission or any regulatory agency or trading
market, except as required by state or federal securities law, any governmental authority or stock exchange rule, in which case
the Issuer shall provide Subscriber with prior written notice of such disclosure permitted under hereunder.

 

(r) Each
party hereto agrees for the express benefit of the Placement Agent, its respective affiliates and its respective representatives

(2) shall be liable for any improper payment made in accordance with the information provided by the Issuer; (3) makes any representation
or warranty, or has any responsibilities as to the validity, accuracy, value or genuineness of any information, certificates or
documentation delivered by or on behalf of the Issuer pursuant to this Subscription Agreement or the Business Combination Agreement
or any agreement contemplated therein, or in connection with any of the Transactions; or (4) shall be liable (x) for any action
taken, suffered or omitted by any of them in good faith and reasonably believed to be authorized or within the discretion or rights
or powers conferred upon it by this Subscription Agreement, the Business Combination Agreement or any agreement contemplated therein,
or (y) for anything which any of them may do or refrain from doing in connection with this Subscription Agreement, the Business
Combination Agreement or any agreement contemplated therein, except for such party’s own gross negligence, willful misconduct
or bad faith; and

 

    22

     

    

 

(ii) The
Placement Agent, its affiliates and its representatives shall be entitled to (1) rely on, and shall be protected in acting upon,
any certificate, instrument, opinion, notice, letter or any other document or security delivered to any of them by or on behalf
of the Issuer, and (2) be indemnified by the Issuer for acting as Placement Agent hereunder pursuant the indemnification provisions
set forth in the Engagement Letter.

 

(s) 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 any Other Subscription Agreement or other investor under the Other Subscription
Agreements. The decision of Subscriber to purchase the Acquired 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 Issuer, the Target or any of their respective 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. The decision of each Other Subscriber to purchase Other
Acquired Shares pursuant to an Other Subscription Agreement has been made by such Other Subscriber independently of Subscriber
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 Issuer, the Target or any of their
respective subsidiaries which may have been made or given by Subscriber. 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 any 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 any 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 Acquired 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.

 

    23

     

    

 

(t) In
connection with all aspects of this Subscription Agreement, the transactions contemplated hereby and the Transaction, the Issuer
acknowledges and agrees that: (i) the purchase and sale of the Acquired Shares constitute an arm’s-length commercial transaction
between the Issuer, on the one hand, and Subscriber, on the other hand, and the Issuer is capable of evaluating and understanding
and understands and accepts the terms, risks and conditions of the transactions contemplated hereby, (ii) in connection with the
process leading to this Subscription Agreement, the transactions contemplated hereby and the Transactions, Subscriber is and has
been acting solely as a principal and not as a financial advisor, agent or fiduciary, for the Issuer or the Issuer’s affiliates,
stockholders, directors, officers, employees or creditors or any other person, (iii) neither Subscriber nor any of its affiliates
has assumed or will assume an advisory, agency or fiduciary responsibility in the Issuer or the Issuer’s affiliates’
favor with respect to any of this Subscription Agreement, the transactions contemplated hereby, the process leading hereto or
the Transactions (irrespective of whether Subscriber or any of its affiliates have advised or are currently advising the Issuer
or any of its affiliates on other matters) and neither Subscriber nor any of its affiliates has any obligation to the Issuer or
any of the Issuer’s affiliates with respect to the Other Subscription Agreements or the Transactions, (iv) Subscriber and
its affiliates may be engaged in a broad range of transactions that involve interests that differ from the Issuer and its affiliates
and neither Subscriber nor any of its affiliates shall have any obligation to disclose any of such interests, and (v) neither
Subscriber nor any of its affiliates has provided any legal, accounting, regulatory or tax advice with respect to this Subscription
Agreement, any of the transactions contemplated hereby or the Transactions, and the Issuer has consulted its own legal, accounting,
regulatory and tax advisors to the extent the Issuer deemed appropriate. The Issuer waives and releases, to the fullest extent
permitted by law, any claims that it may have against Subscriber and its affiliates with respect to any breach of fiduciary duty
or alleged breach of fiduciary duty as a consequence of this Subscription Agreement, the transactions contemplated hereby or the
Transactions.

 

(u) The
headings herein are for convenience only, do not constitute a part of this Subscription Agreement and shall not be deemed to limit
or affect any of the provisions hereof. The language used in this Subscription Agreement will be deemed to be the language chosen
by the parties to express their mutual intent, and no rules of strict construction will be applied against any party. Unless the
context otherwise requires, (i) all references to Sections, Schedules or Exhibits are to Sections, Schedules or Exhibits contained
in or attached to this Subscription Agreement, (ii) each accounting term not otherwise defined in this Subscription Agreement
has the meaning assigned to it in accordance with GAAP, (iii) words in the singular or plural include the singular and plural
and pronouns stated in either the masculine, the feminine or neuter gender shall include the masculine, feminine and neuter, (iv)
the use of the word “including” in this Subscription Agreement shall be by way of example rather than limitation,
and (v) the word “or” shall not be exclusive.

 

(v) If
Subscriber is a Massachusetts Business Trust, a copy of the Agreement and Declaration of Trust of 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 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 Subscriber or
any affiliate thereof individually but are binding only upon Subscriber or any affiliate thereof and its assets and property.

 

(w) The
Issuer agrees that from the date of this Subscription Agreement through the Closing, none of the terms offered to, or agreed with,
any person or entity with respect to the Other Subscription Agreements is or will be more favorable to such person or entity than
those of Subscriber under this Subscription Agreement.

FORM OF

LOCK-UP AGREEMENT

 

February 9, 2021

CM Life Sciences, Inc.

667 Madison Avenue

New York, NY 10065

 

Ladies and Gentlemen:

 

This
letter agreement (this “Agreement”) relates to that certain Agreement and Plan of Merger entered into as of
February 9, 2021 (as amended, restated, supplemented or modified from time to time, the “Transaction Agreement”),
by and among CM Life Sciences, Inc., a Delaware corporation (“Parent”), Mount Sinai Genomics, Inc., a Delaware
corporation, d/b/a Sema4 (the “Company”) and S-IV Sub, Inc., a Delaware corporation and a direct, wholly-owned
subsidiary of Parent (“Merger Sub”), pursuant to which, among other Transactions, Merger Sub is to merge with
and into the Company (the “Merger”), with the Company continuing on as the surviving entity (the “Surviving
Corporation”) and a wholly owned subsidiary of Parent, on the terms and conditions set forth therein. Capitalized terms
used and not otherwise defined herein are defined in the Transaction Agreement and shall have the meanings given to such terms
in the Transaction Agreement.

 

1.
In order to induce all parties to consummate the transactions contemplated by the Transaction Agreement, the undersigned hereby
agrees that, from the Closing Date until the earliest of: (a) the date that is 180 calendar days from the Closing Date, and
(b) the date following the Closing Date on which Parent completes a liquidation, merger, stock exchange or other similar transaction
that results in all of Parent’s stockholders having the right to exchange their shares of Parent capital stock for cash,
securities or other property (the period between the Closing Date and the earliest of clauses (a) and (b), the “Lock-Up
Period”), the undersigned will not: (i) sell, offer to sell, contract or agree to sell, hypothecate, pledge, grant
any option to purchase or otherwise dispose of or agree to dispose of, directly or indirectly, or establish or increase a put equivalent
position or liquidate or decrease a call equivalent position within the meaning of Section 16 of the Securities Exchange Act
of 1934, as amended, and the rules and regulations of the Securities and Exchange Commission promulgated thereunder (the “Exchange
Act”), with respect to shares of Parent Class A Stock issued to the undersigned pursuant to the Transaction Agreement
(such shares of Parent Class A Stock, the “Lock-up Shares”), (ii) enter into any swap or other arrangement
that transfers to another, in whole or in part, any of the economic consequences of ownership of any of the Lock-up Shares, in
cash or otherwise, or (iii) publicly announce any intention to effect any transaction specified in clause (i) or (ii).
Notwithstanding the foregoing, the undersigned may take any of the actions specified in clauses (i), (ii) and (iii) above at any
time after the first date on which the closing price of Parent Class A Stock has equaled or exceeded $12.00 per share (as adjusted
for stock splits, stock dividends, reorganizations, recapitalizations and the like) for any 20 trading days within any 30-trading
day period commencing at least 150 days after the Closing Date.

 

     

     

    

 

2.
For the avoidance of doubt, none of the restrictions set forth in this Agreement shall apply to: (i) any shares of Parent Class
A Stock purchased by the undersigned in the open market or in any public or private capital raising transaction of Parent or otherwise,
including, without limitation, any shares of Parent Class A Stock issued pursuant to the Subscription Agreements or otherwise to
any shares of Parent Class A Stock (or other securities of Parent) other than the Lock-Up Shares; or (ii) the inclusion of any
Lock-Up Shares (but not the subsequent sale or transfer of such Lock-Up Shares) as part of any resale shelf registration statement
filed pursuant to the A&R Registration Rights Agreement. For the avoidance of any doubt, the parties hereto acknowledge and
agree that the undersigned shall retain all of its rights as a stockholder of Parent during the Lock-up Period, including, without
limitation, the right to vote, and to receive any dividends and distributions in respect of, the Lock-Up Shares.

 

3.
The undersigned hereby authorizes Parent during the Lock-Up Period to cause its transfer agent for the Lock-up Shares to decline
to transfer, and to note stop transfer restrictions on the stock register and other records relating to, the Lock-up Shares for
which the undersigned is the record holder and, in the case of Lock-up Shares for which the undersigned is the beneficial holder
but not the record holder, agrees during the Lock-Up Period to cause the record holder to cause the relevant transfer agent to
decline to transfer, and to note stop transfer restrictions on the stock register and other records relating to, such Lock-up Shares,
if such transfer would constitute a violation or breach of this Agreement.

 

4.
Notwithstanding the foregoing, the undersigned may sell or otherwise transfer Lock-up Shares during the undersigned’s lifetime
or on death (or, if the undersigned is not a natural person, during its existence) (a) if the undersigned is not a natural
person, to its managers, partners, members or other direct or indirect equity holders or to any of its other Affiliates or any
subsidiary, employee, officer, director, investment fund controlled or managed by the undersigned or its Affiliates, or commonly
controlled or managed investment fund, (b) to the immediate family members (including spouses, significant others, lineal
descendants, brothers and sisters) of the undersigned, (c) to a family trust, foundation or partnership established for the
exclusive benefit of the undersigned, its equity holders or any of their respective immediate family members, or (d) to a
charitable foundation controlled by the undersigned, its Affiliates, partners, members or other direct or indirect equityholders
or any of their respective immediate family members; provided, however, that in each such case, any such sale or transfer shall
be conditioned upon entry by such transferees into a written agreement, addressed to Parent, agreeing to be bound by these transfer
restrictions and the other terms and conditions of this Agreement; and provided, further, for the avoidance of doubt, that nothing
contained herein shall limit or restrict the admission of new managers, partners, members or other direct or indirect equityholders
in, or the increase or decrease in the ownership interests of any managers, partners, members or other direct or indirect equity
holders of, any entity holding any of the Lock-up Shares.

 

5.
The undersigned hereby represents and warrants that the undersigned has full power and authority to enter into this Agreement and
that this Agreement constitutes the legal, valid and binding obligation of the undersigned, enforceable in accordance with its
terms. Any obligations of the undersigned shall be binding upon the successors and assigns of the undersigned from and after the
Closing Date.

 

     

     

    

 

6.
This Agreement constitutes the entire agreement and understanding of the parties hereto in respect of the subject matter hereof
and supersedes all prior understandings, agreements, or representations by or among the parties hereto, written or oral, to the
extent they relate in any way to the subject matter hereof. This Agreement may not be changed, amended, modified or waived (other
than to correct a typographical error) as to any particular provision, except by a written instrument executed by all parties hereto.
Parent hereby represents, warrants, covenants and agrees that (i) the Sponsor and each of the stockholders of the Company holding
more than 1% of the Company’s outstanding capital stock has, or substantially contemporaneously with the execution and delivery
hereof shall have, executed and delivered a Lock-Up Agreement substantially identical hereto, except that the lock-up period applicable
to the Sponsor is a period of one year from the Closing Date and (ii) if any such Lock-Up Agreement or the restrictions contained
therein is amended, modified or waived in a manner favorable to such stockholder and that would be favorable to the undersigned
(including, without limitation, to shorten the lock-up period or to provide additional exceptions to the lock-up restrictions),
this Agreement shall be contemporaneously amended in the same manner and Parent shall provide prompt notice thereof to the undersigned,
or (iii) if any such stockholder is released from any or all of the lock-up restrictions under its Lock-Up Agreement, the undersigned
will be similarly and contemporaneously released from the lock-up restrictions hereunder (which, for the avoidance, of doubt will
include a release of the same percentage of the undersigned’s Lock-up Shares) and Parent shall provide prompt notice thereof
to the undersigned.

 

7.
No party hereto may assign either this Agreement or any of its rights, interests, or obligations hereunder without the prior written
consent of the other party. Any purported assignment in violation of this paragraph shall be void and ineffectual and shall not
operate to transfer or assign any interest or title to the purported assignee. This Agreement shall be binding on the undersigned
and its successors and assigns.

 

8.
This Agreement is to be governed by, and construed and enforced in accordance with, the internal laws of the State of Delaware,
without regard to its rules of conflict of laws.

 

9.
TO THE EXTENT NOT PROHIBITED BY APPLICABLE LAW WHICH CANNOT BE WAIVED, EACH OF THE PARTIES HEREBY WAIVES, AND AGREES TO CAUSE EACH
OF HIS, HER OR ITS AFFILIATES TO WAIVE, AND COVENANTS THAT NEITHER IT NOR ANY OF HIS, HER OR ITS AFFILIATES WILL ASSERT (WHETHER
AS PLAINTIFF, DEFENDANT OR OTHERWISE) ANY RIGHT TO TRIAL BY JURY IN ANY FORUM IN RESPECT OF ANY ACTION ARISING OUT OF OR BASED
UPON THIS AGREEMENT OR THE SUBJECT MATTER HEREOF, IN EACH CASE WHETHER NOW EXISTING OR HEREAFTER ARISING. EACH PARTY ACKNOWLEDGES
THAT SUCH PARTY HAS BEEN INFORMED BY THE OTHER PARTIES THAT THIS PARAGRAPH 9 CONSTITUTES A MATERIAL INDUCEMENT UPON WHICH THE PARTIES
ARE RELYING AND WILL RELY IN ENTERING INTO THIS AGREEMENT AND ANY OTHER AGREEMENTS RELATING HERETO OR CONTEMPLATED HEREBY. ANY
PARTY MAY FILE AN ORIGINAL COUNTERPART OR A COPY OF THIS PARAGRAPH 9 WITH ANY COURT AS WRITTEN EVIDENCE OF THE CONSENT OF THE PARTIES
TO THE WAIVER OF THE RIGHT TO TRIAL BY JURY.

 

     

     

    

 

10.
Any term or provision of this Agreement that is found to be invalid or unenforceable in any jurisdiction will, as to that jurisdiction,
be ineffective to the extent of such invalidity or unenforceability without rendering invalid or unenforceable the remaining terms
and provisions of this Agreement or affecting the validity or enforceability of any of the terms or provisions of this Agreement
in any other jurisdiction. If any provision of this Agreement is found to be so broad as to be unenforceable, the provision will
be interpreted to be only so broad as is enforceable.

 

11.
This Agreement may be executed in two or more counterparts, each of which will be deemed an original but all of which will constitute
but one instrument. This Agreement is effective upon delivery of one executed counterpart from each party to the other party. The
signatures of all of the parties need not appear on the same counterpart. The delivery of signed counterparts by email which includes
a copy of the sending party’s signature(s) (including by “.pdf” format) or by electronic transmission is as effective
as signing and delivering the counterpart in person.

 

12.
Any notice, consent or request to be given in connection with any of the terms or provisions of this Agreement shall be in writing
and shall be sent by express mail or similar private courier service, by certified mail (return receipt requested) or email transmission
to the address or email address (as applicable) set forth below such party’s name on the signature page hereto. Each such
notice, consent or request will be effective if given by (a) email, when sent, with no mail undeliverable or other rejection
notice, or (b) any other means specified this paragraph 12, then upon delivery or refusal of delivery at the address specified
in this paragraph 12.

 

13.
This Agreement shall become effective on the Closing Date. This Agreement and the obligations of each party hereunder shall automatically
terminate upon any termination of the Transaction Agreement.
