	 	RE:	 Securities Subscription Agreement 

Ladies and Gentlemen: 
 First Light Acquisition
Group, Inc., a Delaware corporation (the “Company”), is pleased to accept the offer First Light Acquisition Group, LLC, a Delaware limited liability company (the “Subscriber” or “you”), has made to
purchase 4,605,750 shares of the Company’s Class B common stock (the “Shares”), $0.0001 par value per share (the “Class B Common Stock”), up to 600,750 of which are subject to complete
or partial forfeiture by you if the underwriters of the Company’s initial public offering (“IPO”), if any, do not fully exercise their over-allotment option (the “Over-allotment Option”). For the purposes of
this Agreement, references to “Common Stock” are to, collectively, the Class B Common Stock and the Company’s Class A common stock, $0.0001 par value per share (the “Class A Common
Stock”). Pursuant to the Company’s certificate of incorporation, as amended to the date hereof (the “Charter”), shares of Class B Common Stock will convert into shares of Class A Common Stock on a one-for-one basis, subject to adjustment, upon the terms and conditions sets forth in the Charter. Unless the context otherwise requires, as used herein
“Securities” shall refer to the Shares and shall be deemed to include any shares of Class A Common Stock issued upon conversion of the Shares. The terms (this “Agreement”) on which the Company is willing to
sell the Shares to the Subscriber, and the Company and the Subscriber’s agreements regarding such Shares, are as follows: 
 1.
Purchase of Shares. 
 For the sum of $20,025 (the “Purchase Price”), which the Company acknowledges receiving in
cash, the Company hereby sells and issues the Shares to the Subscriber, and the Subscriber hereby purchases the Shares from the Company, subject to forfeiture, on the terms and subject to the conditions set forth in this Agreement. The Subscriber
intends to become a Delaware series limited liability company, following which the Shares will be allocated to each of Series 1 through Series 14 of the Subscriber on a pro rata basis in accordance with capital contributions by the members of each
of Series 1 through Series 14 of the Subscriber. Concurrently with the Subscriber’s execution of this Agreement, the Company shall, at its option, deliver to the Subscriber a certificate registered in the Subscriber’s name representing the
Shares (the “Original Certificate”), or effect such delivery in book-entry form. 

 2. Representations, Warranties and Agreements. 

2.1 Subscriber’s Representations, Warranties and Agreements. To induce the Company to issue the Securities to the Subscriber, the
Subscriber hereby represents and warrants to the Company and agrees with the Company as follows: 
 2.1.1 No Government
Recommendation or Approval. The Subscriber understands that no federal or state agency has passed upon or made any recommendation or endorsement of the offering of the Securities. 

2.1.2 No Conflicts. The execution, delivery and performance of this Agreement and the consummation by the Subscriber of
the transactions contemplated hereby do not violate, conflict with or constitute a default under (i) the formation and governing documents of the Subscriber, (ii) any agreement, indenture or instrument to which the Subscriber is a party or
(iii) any law, statute, rule or regulation to which the Subscriber is subject, or any agreement, order, judgment or decree to which the Subscriber is subject. 

2.1.3 Organization and Authority. The Subscriber is a Delaware limited liability company, validly existing and in good
standing under the laws of Delaware and possesses all requisite power and authority necessary to carry out the transactions contemplated by this Agreement. Upon execution and delivery by you, this Agreement is a legal, valid and binding agreement of
the Subscriber, enforceable against the Subscriber in accordance with its terms, except as such enforceability may be limited by applicable bankruptcy, insolvency, fraudulent conveyance or similar laws affecting the enforcement of creditors’
rights generally and subject to general principles of equity (regardless of whether enforcement is sought in a proceeding at law or in equity). 

2.1.4 Experience, Financial Capability and Suitability. The Subscriber is: (i) sophisticated in financial matters
and is able to evaluate the risks and benefits of the investment in the Securities and (ii) able to bear the economic risk of its investment in the Securities for an indefinite period of time because the Securities have not been registered
under the Securities Act (as defined below) and therefore cannot be sold unless subsequently registered under the Securities Act or an exemption from such registration is available. The Subscriber is capable of evaluating the merits and risks of its
investment in the Company and has the capacity to protect its own interests. The Subscriber must bear the economic risk of this investment until the Securities are sold pursuant to: (i) an effective registration statement under the Securities
Act or (ii) an exemption from registration available with respect to such sale. The Subscriber is able to bear the economic risks of an investment in the Securities and to afford a complete loss of the Subscriber’s investment in the
Securities. 
 2.1.5 Access to Information; Independent Investigation. Prior to the execution of this Agreement, the
Subscriber has had the opportunity to ask questions of and receive answers from representatives of the Company concerning an investment in the Company, as well as the finances, operations, business and prospects of the Company, and the opportunity
to obtain additional information to verify the accuracy of all information so obtained. In determining whether to make this investment, the Subscriber has relied solely on the Subscriber’s own knowledge and understanding of the Company and its
business based upon the Subscriber’s own due diligence investigation and the information furnished pursuant to this paragraph. The Subscriber understands that no person has been authorized to give any information or to make any representations
which were not furnished pursuant to this Section 2 and the Subscriber has not relied on any other representations or information in making its investment decision, whether written or oral, relating to the Company, its operations and/or its
prospects. 

  
 2 

 2.1.6 Regulation D Offering. The Subscriber represents that it is an
“accredited investor” as such term is defined in Rule 501(a) of Regulation D under the Securities Act of 1933, as amended (the “Securities Act”), and acknowledges the sale contemplated hereby is being made in reliance on a
private placement exemption applicable to “accredited investors” within the meaning of Section 501(a) of Regulation D under the Securities Act or similar exemptions under state law. 

2.1.7 Investment Purposes. The Subscriber is purchasing the Securities solely for investment purposes, for the
Subscriber’s own account and not for the account or benefit of any other person, and not with a view towards the distribution or dissemination thereof. The Subscriber did not decide to enter into this Agreement as a result of any general
solicitation or general advertising within the meaning of Rule 502 under the Securities Act. 
 2.1.8 Restrictions on
Transfer; Shell Company. The Subscriber understands the Securities are being offered in a transaction not involving a public offering within the meaning of the Securities Act. The Subscriber understands the Securities will be “restricted
securities” within the meaning of Rule 144(a)(3) under the Securities Act and the Subscriber understands that the certificates or book-entries representing the Securities will contain a legend in respect of such restrictions. If in the future
the Subscriber decides to offer, resell, pledge or otherwise transfer the Securities, such Securities may be offered, resold, pledged or otherwise transferred only pursuant to: (i) registration under the Securities Act, or (ii) an
available exemption from registration. The Subscriber agrees that if any transfer of its Securities or any interest therein is proposed to be made, as a condition precedent to any such transfer, the Subscriber may be required to deliver to the
Company an opinion of counsel satisfactory to the Company. Absent registration or an exemption, the Subscriber agrees not to resell the Securities. The Subscriber further acknowledges that because the Company is a shell company, Rule 144 may not be
available to the Subscriber for the resale of the Securities until at least one year following consummation of the initial business combination of the Company, despite technical compliance with the requirements of Rule 144 and the release or waiver
of any contractual transfer restrictions. 
 2.1.9 No Governmental Consents. No governmental, administrative or other
third party consents or approvals are required, necessary or appropriate on the part of the Subscriber in connection with the transactions contemplated by this Agreement. 

  
 3 

 2.2 Company’s Representations, Warranties and Agreements. To induce the
Subscriber to purchase the Securities, the Company hereby represents and warrants to the Subscriber and agrees with the Subscriber as follows: 

2.2.1 Organization and Corporate Power. The Company is a Delaware corporation and is qualified to do business in every
jurisdiction in which the failure to so qualify would reasonably be expected to have a material adverse effect on the financial condition, operating results or assets of the Company. The Company possesses all requisite corporate power and authority
necessary to carry out the transactions contemplated by this Agreement. 
 2.2.2 No Conflicts. The execution, delivery
and performance of this Agreement and the consummation by the Company of the transactions contemplated hereby do not violate, conflict with or constitute a default under (i) the Charter or bylaws of the Company, (ii) any agreement,
indenture or instrument to which the Company is a party or (iii) any law, statute, rule or regulation to which the Company is subject, or any agreement, order, judgment or decree to which the Company is subject. 

2.2.3 Title to Securities. Upon issuance in accordance with, and payment pursuant to, the terms hereof and the Charter,
the Securities will be duly and validly issued, fully paid and non-assessable. Upon issuance in accordance with, and payment pursuant to, the terms hereof and the Charter, the Subscriber will have or receive
good title to the Securities, free and clear of all liens, claims and encumbrances of any kind, other than (a) transfer restrictions hereunder and under the other agreements to which the Securities may be subject, (b) transfer restrictions
under federal and state securities laws, and (c) liens, claims or encumbrances imposed due to the actions of the Subscriber. 

2.2.4 No Adverse Actions. There are no actions, suits, investigations or proceedings pending, threatened against or
affecting the Company which: (i) seek to restrain, enjoin, prevent the consummation of or otherwise affect the transactions contemplated by this Agreement or (ii) question the validity or legality of any transactions or seeks to recover
damages or to obtain other relief in connection with any transactions. 
 2.2.5 Authorization. The shares of
Class A Common Stock issuable upon conversion of the Shares have been duly authorized and reserved for issuance upon such conversion. 

3. Forfeiture of Shares. 

3.1 Partial or No Exercise of the Over-allotment Option. In the event the Over-allotment Option granted to the underwriters of the IPO
is not exercised in full, the Subscriber acknowledges and agrees that it (or, if applicable, it and any transferees of Shares) shall forfeit any and all rights to such number of Shares (up to an aggregate of 600,750 Shares and pro rata based upon
the percentage of the Over-allotment Option exercised) such that immediately following such forfeiture, the Subscriber (and any such transferees) will own an aggregate number of Shares equal to 16.02% of the issued and outstanding Common Stock
immediately following the IPO. 

  
 4 

 3.2 Termination of Rights as Stockholder. If any of the Shares are forfeited in
accordance with this Section 3, then after such time the Subscriber (or successor in interest), shall no longer have any rights as a holder of such forfeited Shares, and the Company shall take such action as is appropriate to cancel such
forfeited Shares. 
 3.3 Share Certificates. In the event an adjustment to the Original Certificates, if any, is required pursuant to
this Section 3, then the Subscriber shall return such Original Certificates to the Company or its designated agent as soon as practicable upon its receipt of notice from the Company advising the Subscriber of such adjustment, following which a
new certificate (the “New Certificate”), if any, shall be issued in such amount representing the adjusted number of Shares held by the Subscriber. The New Certificate, if any, shall be returned to the Subscriber as soon as
practicable. Any such adjustment for any uncertificated securities held by the Subscriber shall be made in book-entry form. 
 4. Waiver
of Liquidation Distributions; Redemption Rights. In connection with the Shares purchased pursuant to this Agreement, the Subscriber hereby waives any and all right, title, interest or claim of any kind in or to any distributions by the Company
from the trust account which will be established for the benefit of the Company’s public stockholders and into which substantially all of the proceeds of the IPO will be deposited (the “Trust Account”), in the event of a
liquidation of the Company upon the Company’s failure to timely complete an initial business combination. For purposes of clarity, in the event the Subscriber purchases securities in the IPO or in the aftermarket, any Class A Common Stock
so purchased shall be eligible to receive any liquidating distributions by the Company. However, in no event will the Subscriber have the right to redeem any shares of Common Stock held by it into funds held in the Trust Account upon the successful
completion of an initial business combination. 
 5. Restrictions on Transfer. 

5.1 Securities Law Restrictions. In addition to any restrictions to be contained in that certain letter agreement (commonly known as an
“Insider Letter”) dated on or prior to the closing of the IPO by and between the Subscriber and the Company, the Subscriber agrees not to sell, transfer, pledge, hypothecate or otherwise dispose of all or any part of the Securities
unless, prior thereto (a) a registration statement on the appropriate form under the Securities Act and applicable state securities laws with respect to the Securities proposed to be transferred shall then be effective or (b) the Company
has received an opinion from counsel reasonably satisfactory to the Company, that such registration is not required because such transaction is exempt from registration under the Securities Act and the rules promulgated by the Securities and
Exchange Commission thereunder and with all applicable state securities laws. 
 5.2 Lock-up.
The Subscriber acknowledges that the Securities will be subject to lock-up provisions (the “Lock-up”) contained in the Insider Letter. 

  
 5 

 5.3 Restrictive Legends. All certificates representing the Securities shall have
endorsed thereon legends substantially as follows: 
 “THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE
SECURITIES ACT OF 1933, AS AMENDED, OR ANY STATE SECURITIES LAWS AND NEITHER THE SECURITIES NOR ANY INTEREST THEREIN MAY BE OFFERED, SOLD, TRANSFERRED, PLEDGED OR OTHERWISE DISPOSED OF EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER
SUCH ACT OR SUCH LAWS OR AN EXEMPTION FROM REGISTRATION UNDER SUCH ACT AND SUCH LAWS WHICH, IN THE OPINION OF COUNSEL (IF THE COMPANY SO REQUESTS), IS AVAILABLE.” 

“THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO A LOCKUP AND MAY NOT BE OFFERED, SOLD, TRANSFERRED, PLEDGED OR OTHERWISE
DISPOSED DURING THE TERM OF THE LOCKUP.” 
 5.4 Additional Shares or Substituted Securities. In the event of the declaration
of a share dividend, the declaration of an extraordinary dividend payable in a form other than Common Stock, a spin-off, a share split, an adjustment in conversion ratio, a recapitalization or a similar
transaction affecting the Company’s outstanding Common Stock without receipt of consideration, any new, substituted or additional securities or other property which are by reason of such transaction distributed with respect to any Securities
subject to this Section 5 or into which such Securities thereby become convertible shall immediately be subject to this Section 5 and Section 3. Appropriate adjustments to reflect the distribution of such securities or property shall
be made to the number and/or class of Securities subject to this Section 5 and Section 3. 
 5.5 Registration Rights. The
Subscriber acknowledges that the Shares are being purchased pursuant to an exemption from the registration requirements of the Securities Act and will become freely tradable only after certain conditions are met or they are registered pursuant to a
registration rights agreement to be entered into with the Company prior to the closing of the IPO (the “Registration Rights Agreement”). 

6. Other Agreements. 

6.1 Further Assurances. The Subscriber agrees to execute such further instruments and to take such further action as may reasonably be
necessary to carry out the intent of this Agreement. 
 6.2 Notices. All notices, statements or other documents which are required or
contemplated by this Agreement shall be: in writing and delivered (i) personally or sent by first class registered or certified mail, overnight courier service or facsimile or electronic transmission to the address designated in writing,
(ii) by facsimile to the number most recently provided to such party or such other address or fax number as may be designated in writing by such party or (iii) by electronic mail, to the electronic mail address most recently provided to
such party or such other electronic mail address as may be designated in writing by such party. Any notice or other communication so transmitted shall be deemed to have been given on the day of delivery, if delivered personally, on the business day
following receipt of written confirmation, if sent by facsimile or electronic transmission, one (1) business day after delivery to an overnight courier service or five (5) days after mailing if sent by mail. 

  
 6 

 6.3 Entire Agreement. This Agreement, together with the Insider Letter and the
Registration Rights Agreement, each substantially in the form to be filed as an exhibit to the Registration Statement, embodies the entire agreement and understanding between the Subscriber and the Company with respect to the subject matter hereof
and supersedes all prior oral or written agreements and understandings relating to the subject matter hereof. 
 6.4 Modifications and
Amendments. The terms and provisions of this Agreement may be modified or amended only by written agreement executed by all parties hereto. 

6.5 Waivers and Consents. The terms and provisions of this Agreement may be waived, or consent for the departure therefrom granted,
only by written document executed by the party entitled to the benefits of such terms or provisions. No such waiver or consent shall be deemed to be or shall constitute a waiver or consent with respect to any other terms or provisions of this
Agreement, whether or not similar. Each such waiver or consent shall be effective only in the specific instance and for the purpose for which it was given, and shall not constitute a continuing waiver or consent. 

6.6 Assignment. The rights and obligations under this Agreement may not be assigned by either party hereto without the prior written
consent of the other party. 
 6.7 Benefit. All statements, representations, warranties, covenants and agreements in this Agreement
shall be binding on the parties hereto and shall inure to the benefit of the respective successors and permitted assigns of each party hereto. Nothing in this Agreement shall be construed to create any rights or obligations except among the parties
hereto, and no person or entity shall be regarded as a third-party beneficiary of this Agreement. 
 6.8 Governing Law. This
Agreement and the rights and obligations of the parties hereunder shall be construed in accordance with and governed by the laws of New York applicable to contracts wholly performed within the borders of such state, without giving effect to the
conflict of law principles thereof. 
 6.9 Severability. In the event that any court of competent jurisdiction shall determine that
any provision, or any portion thereof, contained in this Agreement shall be unreasonable or unenforceable in any respect, then such provision shall be deemed limited to the extent that such court deems it reasonable and enforceable, and as so
limited shall remain in full force and effect. In the event that such court shall deem any such provision, or portion thereof, wholly unenforceable, the remaining provisions of this Agreement shall nevertheless remain in full force and effect. 

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

  
 7 

 6.11 Survival of Representations and Warranties. All representations and warranties
made by the parties hereto in this Agreement or in any other agreement, certificate or instrument provided for or contemplated hereby, shall survive the execution and delivery hereof and any investigations made by or on behalf of the parties. 

6.12 No Broker or Finder. Each of the parties hereto represents and warrants to the other that no broker, finder or other financial
consultant has acted on its behalf in connection with this Agreement or the transactions contemplated hereby in such a way as to create any liability on the other. Each of the parties hereto agrees to indemnify and save the other harmless from any
claim or demand for commission or other compensation by any broker, finder, financial consultant or similar agent claiming to have been employed by or on behalf of such party and to bear the cost of legal expenses incurred in defending against any
such claim. 
 6.13 Headings and Captions. The headings and captions of the various subdivisions of this Agreement are for
convenience of reference only and shall in no way modify or affect the meaning or construction of any of the terms or provisions hereof. 

6.14 Counterparts. This Agreement may be executed in one or more counterparts, all of which when taken together shall be considered one
and the same agreement and shall become effective when counterparts have been signed by each party and delivered to the other party, it being understood that both parties need not sign the same counterpart. In the event that any signature is
delivered by facsimile transmission or any other form of electronic delivery, such signature shall create a valid and binding obligation of the party executing (or on whose behalf such signature is executed) with the same force and effect as if such
signature page were an original thereof. 
 6.15 Construction. The parties hereto have participated jointly in the negotiation and
drafting of this Agreement. If an ambiguity or question of intent or interpretation arises, this Agreement will be construed as if drafted jointly by the parties hereto and no presumption or burden of proof will arise favoring or disfavoring any
party hereto because of the authorship of any provision of this Agreement. The words “include,” “includes,” and “including” will be deemed to be followed by “without limitation.”
Pronouns in masculine, feminine, and neuter genders will be construed to include any other gender, and words in the singular form will be construed to include the plural and vice versa, unless the context otherwise requires. The words “this
Agreement,” “herein,” “hereof,” “hereby,” “hereunder,” and words of similar import refer to this Agreement as a whole and not to any particular subdivision unless expressly
so limited. The parties hereto intend that each representation, warranty, and covenant contained herein will have independent significance. If any party hereto has breached any representation, warranty, or covenant contained herein in any respect,
the fact that there exists another representation, warranty or covenant relating to the same subject matter (regardless of the relative levels of specificity) which such party hereto has not breached will not detract from or mitigate the fact that
such party hereto is in breach of the first representation, warranty, or covenant. 

  
 8 

 6.16 Mutual Drafting. This Agreement is the joint product of the Subscriber and the
Company and each provision hereof has been subject to the mutual consultation, negotiation and agreement of such parties and shall not be construed for or against any party hereto. 

7. Voting and Tender of Shares. The Subscriber agrees to vote the Shares in favor of an initial business combination that the Company
negotiates and submits for approval to the Company’s stockholders and shall not seek redemption with respect to any of the Shares. Additionally, the Subscriber agrees not to tender any Shares in connection with a tender offer presented to the
Company’s stockholders in connection with an initial business combination negotiated by the Company. 
 8. Indemnification. Each
party shall indemnify the other against any loss, cost or damages (including reasonable attorney’s fees and expenses) incurred as a result of such party’s breach of any representation, warranty, covenant or agreement in this Agreement.

The Company intends to consummate an initial public offering of the Company’s units (the “Public Offering”), each unit
consisting of one share of the Company’s Class A common stock, par value $0.0001 per share (each, a “Share”), and one-third of one redeemable warrant as set forth in the
Company’s registration statement on Form S-1, filed with the Securities and Exchange Commission (the “SEC”), File Number 333-[•] (the

 Each
whole warrant entitles the holder to purchase one Share at an exercise price of $11.50 per Share; and 
 Each purchaser has agreed to
purchase from the Company the number of redeemable warrants set forth opposite such Purchaser’s name on Schedule I hereto (or up to such number of redeemable warrants set forth opposite such Purchaser’s name under the column
“Over-Allotment” on Schedule I if the over-allotment option in connection with the Public Offering is exercised in full) (the “Private Placement Warrants”), each whole Private Placement Warrant entitling the holder

 NOW THEREFORE, in consideration of the mutual promises contained in this

by each Purchaser of the Over-allotment Purchase Price by wire transfer of immediately available funds to the Company, the Company, at its option, shall deliver a certificate evidencing the Private Placement Warrants purchased on such date duly
registered in such Purchaser’s name to the relevant Purchaser, or effect such delivery in book-entry form.

A. Organization and Corporate Power. The Company is a corporation duly incorporated, validly existing and in good standing under the

is required in connection with the execution, delivery and performance by the Company of this Agreement or the consummation by the Company of any other transactions contemplated hereby. 

E. Regulation D Qualification. Neither the Company nor, to its knowledge, any of its affiliates, officers, directors or beneficial

 Section 3. Representations and Warranties of the Purchasers. As a material
inducement to the Company to enter into this Agreement and issue and sell the Private Placement Warrants to each Purchaser, each Purchaser hereby represents and warrants to the Company as to itself (which representations and warranties shall survive
each Closing Date) that: 
 A. Organization and Requisite Authority. Such Purchaser possesses all requisite power and authority
necessary to carry out the transactions contemplated by this Agreement. 
 B. Authorization; No Breach. 

(i) This Agreement constitutes a valid and binding obligation of such Purchaser, enforceable in accordance with its terms, subject to
bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and other laws of general applicability relating to or affecting creditors’ rights and to general equitable principles (whether considered in a proceeding in equity or
law). 
 (ii) The execution and delivery by such Purchaser of this Agreement and the fulfillment of and compliance with the terms hereof by
such Purchaser does not and shall not as of each Closing Date conflict with or result in a breach by such Purchaser of the terms, conditions or provisions of any agreement, instrument, order, judgment or decree to which such Purchaser is subject.

 C. Investment Representations. 

(i) Such Purchaser is acquiring the Private Placement Warrants and, upon exercise of the Private Placement Warrants, the Shares issuable upon
such exercise (collectively, the “Securities”), for such Purchaser’s own account, for investment purposes only and not with a view towards, or for resale in connection with, any public sale or distribution thereof. 

(ii) Such Purchaser is an “accredited investor” as such term is defined in Rule 501(a)(3) of Regulation D under the Securities Act.

 (iii) Such Purchaser understands that the Securities are being offered and will be sold to it in reliance on specific exemptions from the
registration requirements of the United States federal and state securities laws and that the Company is relying upon the truth and accuracy of, and such Purchaser’s compliance with, the representations and warranties of such Purchaser set
forth herein in order to determine the availability of such exemptions and the eligibility of such Purchaser to acquire such Securities. 

(iv) Such Purchaser did not decide to enter into this Agreement as a result of any general solicitation or general advertising within the
meaning of Rule 502(c) under the Securities Act. 
 (v) Such Purchaser has been furnished with all materials relating to the business,
finances and operations of the Company and materials relating to the offer and sale of the Securities which have been requested by the Purchaser. Such Purchaser has been afforded the opportunity to ask questions of the executive officers and
directors of the Company. Such Purchaser understands that its investment in the Securities involves a high degree of risk and it has sought such accounting, legal and tax advice as it has considered necessary to make an informed investment decision
with respect to the acquisition of the Securities. 

  
 4 

 (vi) Such Purchaser understands that no United States federal or state agency or any other
government or governmental agency has passed on or made any recommendation or endorsement of the Securities or the fairness or suitability of the investment in the Securities by such Purchaser nor have such authorities passed upon or endorsed the
merits of the offering of the Securities. 
 (vii) Such Purchaser understands that: (a) the Securities have not been and are not being
registered under the Securities Act or any state securities laws, and may not be offered for sale, sold, assigned or transferred unless (1) subsequently registered thereunder or (2) sold in reliance on an exemption therefrom; and
(b) except as specifically set forth in the Registration and Stockholders Rights Agreement, neither the Company nor any other person is under any obligation to register the Securities under the Securities Act or any state securities laws or to
comply with the terms and conditions of any exemption thereunder. In this regard, such Purchaser understands that the SEC has taken the position that promoters or affiliates of a blank check company and their transferees, both before and after an
initial business combination, are deemed to be “underwriters” under the Securities Act when reselling the securities of a blank check company. Based on that position, Rule 144 adopted pursuant to the Securities Act would not be available
for resale transactions of the Securities despite technical compliance with the requirements of such Rule, and the Securities can be resold only through a registered offering or in reliance upon another exemption from the registration requirements
of the Securities Act. 
 (viii) Such Purchaser has such knowledge and experience in financial and business matters, knowledge of the high
degree of risk associated with investments in the securities of companies in the development stage such as the Company, is capable of evaluating the merits and risks of an investment in the Securities and is able to bear the economic risk of an
investment in the Securities in the amount contemplated hereunder for an indefinite period of time. Such Purchaser has adequate means of providing for its current financial needs and contingencies and will have no current or anticipated future needs
for liquidity which would be jeopardized by the investment in the Securities. Such Purchaser can afford a complete loss of its investment in the Securities. 

(ix) Such Purchaser understands that the Private Placement Warrants shall bear the legend restricting transfers substantially in the form set
forth in the Warrant Agreement. 
 Section 4. Conditions of the Purchaser’s Obligations. The obligations of each Purchaser to
purchase and pay for the Private Placement Warrants to be purchased on a Closing Date are subject to the fulfillment, on or before each such Closing Date, of each of the following conditions: 

A. Representations and Warranties. The representations and warranties of the Company contained in Section 2 shall be true and

C. No Injunction. No litigation, statute, rule, regulation, executive order, decree, ruling or injunction shall have been enacted,
entered, promulgated or endorsed by or in any court or governmental authority of competent jurisdiction or any self-regulatory organization having authority over the matters contemplated hereby, which prohibits the consummation of any of the
transactions contemplated by this Agreement or the Warrant Agreement. 

  
 5 

 D. Warrant Agreement. The Company shall have entered into a Warrant Agreement with a

 E. Registration and Stockholders Rights Agreement. The Company shall have

D. Warrant Agreement. The Company shall have entered into a Warrant Agreement with a warrant agent on terms satisfactory to the Company.

 Section 6. Termination. This Agreement may be terminated at any time after [•], 2021 upon the election by either the
Company or each Purchaser upon written notice to the other party if the closing of the Public Offering does not occur prior to such date. 

Section 7. Survival of Representations and Warranties. All of the representations and warranties contained herein shall survive each
Closing Date. 
 Section 8. Definitions. Terms used but not otherwise defined in this Agreement shall have the meaning assigned to
such terms in the Registration Statement. 
 Section 9. Miscellaneous. 

A. Successors and Assigns. Except as otherwise expressly provided herein, all covenants and agreements contained in this Agreement by or
on behalf of any of the parties hereto shall bind and inure to the benefit of the respective successors of the parties hereto whether so expressed or not. Notwithstanding the foregoing or anything to the contrary herein, the parties may not assign
this Agreement, other than assignments by each Purchaser to its affiliates thereof. 

  
 6 

 B. Severability. Whenever possible, each provision of this Agreement shall be
interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Agreement is held to be prohibited by or invalid under applicable law, such provision shall be ineffective only to the extent of such
prohibition or invalidity, without invalidating the remainder of this Agreement. 
 C. Counterparts. This Agreement may be executed
simultaneously in two or more counterparts, none of which need contain the signatures of more than one party, but all such counterparts taken together shall constitute one and the same agreement. The words “execution”, “signed”,
“signature” and words of like import in this Agreement or in any certificate, agreement or document related to this Agreement shall include images of manually executed signatures transmitted by facsimile or other electronic format
(including, without limitation, “pdf”, “tif” or “jpg”) and other electronic signatures (including, without limitation, DocuSign and AdobeSign). The use of electronic signatures and electronic records (including, without
limitation, any contract or other record created, generated, sent, communicated, received, or stored by electronic means) shall be of the same legal effect, validity and enforceability as a manually executed signature or use of a paper-based
recordkeeping system to the fullest extent permitted by applicable law, including the U.S. Electronic Signatures in Global and National Commerce Act, the New York State Electronic Signatures and Records Act and any other applicable law, including,
without limitation, any state law based on the Uniform Electronic Transactions Act of the United States or the Uniform Commercial Code of the United States. 

D. Descriptive Headings; Interpretation. The descriptive headings of this Agreement are inserted for convenience only and do not
constitute a substantive part of this Agreement. The use of the word “including” in this Agreement shall be by way of example rather than by limitation. 

E. Governing Law. This Agreement shall be deemed to be a contract made under the laws of the State of New York and for all purposes
shall be construed in accordance with the internal laws of the State of New York, without giving effect to the conflict of law principles thereof. The parties hereto irrevocably submit to the exclusive jurisdiction of any federal court sitting in
the Southern District of New York or any state court located in New York County, State of New York, over any suit, action or proceeding arising out of or relating to this Agreement. To the fullest extent they may effectively do so under applicable
law, the parties hereto irrevocably waive and agree not to assert, by way of motion, as a defense or otherwise, any claim that they are not subject to the jurisdiction of any such court, any objection that they may now or hereafter have to the
laying of the venue of any such suit, action or proceeding brought in any such court and any claim that any such suit, action or proceeding brought in any such court has been brought in an in convenient forum. 

F. Amendments. This Agreement may not be amended, modified or waived as to any particular provision, except by a written instrument
