 REGISTRATIONS

 2.1    Demand Registration. 

2.1.1    Request for Registration. Subject to the provisions of subsection 2.1.4 and
Section 2.4 hereof, at any time and from time to time on or after the date the Company consummates the initial Business Combination, the Holders of at least a
majority-in-interest of the then-outstanding number of Registrable Securities (the “Demanding Holders”) may make a written demand for Registration of
all or part of their Registrable Securities, which written demand shall describe the amount and type of securities to be included in such Registration and the intended method(s) of distribution thereof (such written demand a “Demand
Registration”). The Company shall, within ten (10) days of the Company’s receipt of the Demand Registration, notify, in writing, all other Holders of Registrable Securities of such demand, and each Holder of Registrable Securities
who thereafter wishes to include all or a portion of such Holder’s Registrable Securities in a Registration pursuant to a Demand Registration (each such Holder that includes all or a portion of such Holder’s Registrable Securities in such
Registration, a “Requesting Holder”) shall so notify the Company, in writing, within five (5) days after the receipt by the Holder of the notice from the Company. Upon receipt by the Company of any such written notification
from a Requesting Holder(s) to the Company, such Requesting Holder(s) shall be entitled to have their Registrable Securities included in a Registration pursuant to a Demand Registration and the Company shall effect, as soon thereafter as
practicable, but not more than forty-five (45) days immediately after the Company’s receipt of the Demand Registration, the Registration of all Registrable Securities requested by the Demanding Holders and Requesting Holders pursuant to
such Demand Registration. Under no circumstances shall the Company be obligated to effect more than an aggregate of three (3) Registrations pursuant to a Demand Registration under this subsection 2.1.1 with respect to any or all
Registrable Securities; provided, however, that (i) this limitation shall not apply to any Demand Registration initiated by Metric, which shall be governed by Section 3.6 hereof and (ii) a
Registration shall not be counted for such purposes unless a Form S-1 or any similar long-form registration statement that may be available at such time (“Form
S-1”) has become effective and all of the Registrable Securities requested by the Requesting Holders to be registered for resale on behalf of the Requesting Holders in such Form S-1 Registration have been sold, in accordance with Section 3.1 of this Agreement. 

  
 6 

 2.1.2    Effective Registration. Notwithstanding the provisions
of subsection 2.1.1 above or any other part of this Agreement, a Registration pursuant to a Demand Registration shall not count as a Registration unless and until (i) the Registration Statement filed with the Commission with respect to a
Registration pursuant to a Demand Registration has been declared effective by the Commission and (ii) the Company has complied with all of its obligations under this Agreement with respect thereto; provided, further, that if,
after such Registration Statement has been declared effective, an offering of Registrable Securities in a Registration pursuant to a Demand Registration is subsequently interfered with by any stop order or injunction of the Commission, federal or
state court or any other governmental agency, the Registration Statement with respect to such Registration shall be deemed not to have been declared effective, unless and until, (i) such stop order or injunction is removed, rescinded or
otherwise terminated, and (ii) a majority-in-interest of the Demanding Holders initiating such Demand Registration thereafter affirmatively elect to continue with
such Registration and accordingly notify the Company in writing, but in no event later than five (5) days, of such election; provided, further, that the Company shall not be obligated or required to file another Registration
Statement until the Registration Statement that has been previously filed with respect to a Registration pursuant to a Demand Registration becomes effective or is subsequently terminated. 

2.1.3    Underwritten Offering. Subject to the provisions of subsection 2.1.4 and
Section 2.4 hereof, if a majority-in-interest of the Demanding Holders so advise the Company as part of their Demand Registration that the
offering of the Registrable Securities pursuant to such Demand Registration shall be in the form of an Underwritten Offering, then the right of such Demanding Holder or Requesting Holder (if any) to include its Registrable Securities in such
Registration shall be conditioned upon such Holder’s participation in such Underwritten Offering and the inclusion of such Holder’s Registrable Securities in such Underwritten Offering to the extent provided herein. All such Holders
proposing to distribute their Registrable Securities through an Underwritten Offering under this subsection 2.1.3 shall enter into an underwriting agreement in customary form with the Underwriter(s) selected for such Underwritten Offering by
the majority-in-interest of the Demanding Holders initiating the Demand Registration. 

2.1.4    Reduction of Underwritten Offering. If the managing Underwriter(s) in an Underwritten Registration
pursuant to a Demand Registration, in good faith, advises the Company, the Demanding Holders and the Requesting Holders (if any) in writing that the dollar amount or number of Registrable Securities that the Demanding Holders and the Requesting
Holders (if any) desire to sell, taken together with all other shares of Common Stock or other equity securities that the Company desires to sell for its own account and the shares of Common Stock, if any, as to which a Registration has been
requested pursuant to separate written contractual piggy-back registration rights held by any other stockholders who desire to sell, exceeds the maximum dollar amount or maximum number of equity securities that can be sold in the Underwritten
Offering without adversely affecting the proposed offering price, the timing, the distribution method, or the probability of success of such offering (such maximum dollar amount or maximum number of such securities, as applicable, the
“Maximum Number of Securities”), then the Company shall include in such Underwritten Offering, as follows: (i) first, the Registrable Securities of the Demanding Holders and the Requesting Holders (if any) (pro rata based on
the respective number of Registrable Securities that each Demanding Holder and Requesting Holder (if any) has requested be included in such Underwritten Registration and the aggregate number of Registrable Securities that the Demanding Holders and
Requesting Holders have requested be included in such Underwritten Registration (such proportion is referred to herein as “Pro Rata”)) that can be sold without exceeding the Maximum Number of Securities;

  
 7 

 
(ii) second, to the extent that the Maximum Number of Securities has not been reached under the foregoing clause (i), the shares of Common Stock or other equity securities that the Company
desires to sell, which can be sold without exceeding the Maximum Number of Securities and (iii) third, to the extent that the Maximum Number of Securities has not been reached under the foregoing clauses (i) and (ii), the shares of Common
Stock or other equity securities of other persons or entities that the Company is obligated to register for resale in a Registration pursuant to separate written contractual arrangements with such persons and that can be sold without exceeding the
Maximum Number of Securities. 
 2.1.5    Demand Registration Withdrawal. A majority-in-interest of the Demanding Holders initiating a Demand Registration or a majority-in-interest of the Requesting
Holders (if any), pursuant to a Registration under subsection 2.1.1 shall have the right to withdraw from a Registration pursuant to such Demand Registration for any or no reason whatsoever upon written notification to the Company and the
Underwriter(s) (if any) of their intention to withdraw from such Registration prior to the effectiveness of the Registration Statement filed with the Commission with respect to the Registration of their Registrable Securities pursuant to such Demand
Registration. Notwithstanding anything to the contrary in this Agreement, the Company shall be responsible for the Registration Expenses incurred in connection with a Registration pursuant to a Demand Registration prior to its withdrawal under this
subsection 2.1.5. 
 2.2    Piggyback Registration. 

2.2.1    Piggyback Rights. If, at any time on or after the date the Company consummates its initial Business
Combination, the Company proposes to file a Registration Statement under the Securities Act with respect to an offering of equity securities, or securities or other obligations exercisable or exchangeable for, or convertible into equity securities,
for its own account or for the account of stockholders of the Company (or by the Company and by the stockholders of the Company including, without limitation, pursuant to Section 2.1 hereof), other than a Registration
Statement (i) filed in connection with any employee stock option or other benefit plan, (ii) for a rights offering or an exchange offer or offering of securities solely to the Company’s existing stockholders, (iii) for an
offering of debt that is convertible into equity securities of the Company or (iv) for a dividend reinvestment plan, then the Company shall give written notice of such proposed filing to all of the Holders of Registrable Securities as soon as
practicable but not less than ten (10) days before the anticipated filing date of such Registration Statement, which notice shall (A) describe the amount and type of securities to be included in such offering, the intended method(s) of
distribution, and the name of the proposed managing Underwriter(s) (if any) in such offering, and (B) offer to all of the Holders of Registrable Securities the opportunity to register the resale of such number of Registrable Securities as such
Holders may request in writing within five (5) days after receipt of such written notice (such Registration a “Piggyback Registration”). The Company shall, in good faith, cause such Registrable Securities to be included in such
Piggyback Registration and shall use its best efforts to cause the managing Underwriter(s) of a proposed Underwritten Offering to permit the Registrable Securities requested by the Holders pursuant to this subsection 2.2.1 to be included in a
Piggyback Registration on the same terms and conditions as any similar securities of the Company included in such Registration and to permit the sale or other disposition of such Registrable Securities in accordance with the intended method(s) of
distribution thereof. All such 

  
 8 

 
Holders proposing to distribute their Registrable Securities through an Underwritten Offering under this subsection 2.2.1 shall enter into an underwriting agreement in customary form with
the Underwriter(s) selected for such Underwritten Offering by the Company. 
 2.2.2    Reduction of Piggyback
Registration. If the managing Underwriter(s) in an Underwritten Registration that is to be a Piggyback Registration, in good faith, advises the Company and the Holders of Registrable Securities participating in the Piggyback Registration in
writing that the dollar amount or number of shares of Common Stock that the Company desires to sell, taken together with (i) the shares of Common Stock, if any, as to which Registration has been demanded pursuant to separate written contractual
arrangements with persons or entities other than the Holders of Registrable Securities hereunder, (ii) the Registrable Securities as to which registration has been requested pursuant to Section 2.2 hereof, and
(iii) the shares of Common Stock, if any, as to which Registration has been requested pursuant to separate written contractual piggy-back registration rights of other stockholders of the Company, exceeds the Maximum Number of Securities, then:

 (a)    If the Registration is undertaken for the Company’s account, the Company shall include in
any such Registration (A) first, the shares of Common Stock or other equity securities that the Company desires to sell for its own account, which can be sold without exceeding the Maximum Number of Securities; (B) second, to the extent
that the Maximum Number of Securities has not been reached under the foregoing clause (A), the Registrable Securities of Holders exercising their rights to register the resale of their Registrable Securities pursuant to subsection 2.2.1
hereof, Pro Rata (based on the respective number of Registrable Securities that each Holder has so requested), which can be sold without exceeding the Maximum Number of Securities; and (C) third, to the extent that the Maximum Number of
Securities has not been reached under the foregoing clauses (A) and (B), the shares of Common Stock, if any, as to which Registration has been requested pursuant to written contractual piggy-back registration rights of other stockholders of the
Company, which can be sold without exceeding the Maximum Number of Securities; 
 (b)    If the
Registration is pursuant to a request by persons or entities other than the Holders of Registrable Securities, then the Company shall include in any such Registration (A) first, the shares of Common Stock or other equity securities, if any, of

 9 

 
the extent that the Maximum Number of Securities has not been reached under the foregoing clauses (A), (B) and (C), the shares of Common Stock or other equity securities for the account of other
persons or entities that the Company is obligated to register for resale pursuant to separate written contractual arrangements with such persons or entities, which can be sold without exceeding the Maximum Number of Securities. 

2.2.3    Piggyback Registration Withdrawal. Any Holder of Registrable Securities shall have the right to withdraw
from a Piggyback Registration for any or no reason whatsoever upon written notification to the Company and the Underwriter(s) (if any) of his, her or its intention to withdraw from such Piggyback Registration prior to the effectiveness of the
Registration Statement filed with the Commission with respect to such Piggyback Registration (or in the case of an Underwritten Registration pursuant to Rule 415 under the Securities Act, at least two business days prior to the time of pricing of
the applicable offering). The Company (whether on its own good faith determination or as the result of a request for withdrawal by persons pursuant to separate written contractual obligations) may withdraw a Registration Statement filed with the
Commission in connection with a Piggyback Registration at any time prior to the effectiveness of such Registration Statement. Notwithstanding anything to the contrary in this Agreement, the Company shall be responsible for the Registration Expenses
incurred in connection with the Piggyback Registration prior to its withdrawal under this subsection 2.2.3. 

2.2.4    Unlimited Piggyback Registration Rights. For purposes of clarity, any Registration effected pursuant to
Section 2.2 hereof shall not be counted as a Registration pursuant to a Demand Registration effected under Section 2.1 hereof. 

2.3    Shelf Registration 

2.3.1    The Holders of Registrable Securities may at any time, and from time to time, request in writing that the Company,
pursuant to Rule 415 under the Securities Act (or any successor rule promulgated thereafter by the Commission), register the resale of any or all of their Registrable Securities on Form S-3 or any similar
short form registration statement that may be available at such time (“Form S-3”), or if the Company is ineligible to use Form S-3, on Form S-1; a registration statement filed pursuant to this subsection 2.3.1 (a “Shelf”) shall provide for the resale of the Registrable Securities included therein pursuant to any method or
combination of methods legally available to, and requested by, any Holder; provided, however, that the Company shall not be obligated to effect an Underwritten Offering pursuant to a Shelf or this Section 2.3.
Within five (5) days of the Company’s receipt of a written request from a Holder or Holders of Registrable Securities for a Registration on a Shelf, the Company shall promptly give written notice of the proposed Registration to all other
Holders of Registrable Securities, and each Holder of Registrable Securities who thereafter wishes to include all or a portion of such Holder’s Registrable Securities in such Registration shall so notify the Company, in writing, within ten
(10) days after the receipt by the Holder of the notice from the Company. As soon as practicable thereafter, but not more than twelve (12) days after the Company’s initial receipt of such written request for a Registration on a Shelf,
the Company shall file a Registration Statement relating to all or such portion of such Holder’s Registrable Securities as are specified in such written request, together with all or such portion of Registrable Securities of

  
 10 

 
any other Holder or Holders joining in such request as are specified in the written notification given by such Holder or Holders; provided, however, that the Company shall not be
obligated to effect any such Registration pursuant to this subsection 2.3.1 if the Holders of Registrable Securities, together with the Holders of any other equity securities of the Company entitled to inclusion in such Registration, propose
to sell the Registrable Securities and such other equity securities (if any) at any aggregate price to the public of less than $10,000,000. The Company shall maintain each Shelf in accordance with the terms hereof, and shall prepare and file with
the Commission such amendments, including post-effective amendments, and supplements as may be necessary to keep such Shelf continuously effective, available for use and in compliance with the provisions of the Securities Act until such time as
there are no longer any Registrable Securities included on such Shelf. In the event the Company files a Shelf on Form S-1, the Company shall use its commercially reasonable efforts to convert the Form S-1 to a Form S-3 as soon as reasonably practicable after the Company is eligible to use Form S-3. 

2.3.2    If any Shelf ceases to be effective under the Securities Act for any reason at any time while Registrable
Securities included thereon are still outstanding, the Company shall use its commercially reasonable efforts to as promptly as is reasonably practicable cause such Shelf to again become effective under the Securities Act (including obtaining the
prompt withdrawal of any order suspending the effectiveness of such Shelf), and shall use its commercially reasonable efforts to as promptly as is reasonably practicable amend such Shelf in a manner reasonably expected to result in the withdrawal of
any order suspending the effectiveness of such Shelf or file an additional registration statement (a “Subsequent Shelf Registration”) registering the resale of all Registrable Securities included on such Shelf, and pursuant to any
method or combination of methods legally available to, and requested by, any Holder; provided, however, that the Company shall not be obligated to effect an Underwritten Offering pursuant to a Subsequent Shelf Registration or this
Section 2.3. If a Subsequent Shelf Registration is filed, the Company shall use its commercially reasonable efforts to (i) cause such Subsequent Shelf Registration to become effective under the Securities Act as
promptly as is reasonably practicable after the filing thereof and (ii) keep such Subsequent Shelf Registration continuously effective, available for use and in compliance with the provisions of the Securities Act until such time as there are
no longer any Registrable Securities included thereon. Any such Subsequent Shelf Registration shall be on Form S-3 to the extent that the Company is eligible to use such form. Otherwise, such Subsequent Shelf
Registration shall be on another appropriate form. In the event that any Holder holds Registrable Securities that are not registered for resale on a delayed or continuous basis, the Company, upon request of a Holder shall promptly use its
commercially reasonable efforts to cause the resale of such Registrable Securities to be covered by either, at the Company’s option, a Shelf (including by means of a post-effective amendment) or a Subsequent Shelf Registration and cause the
same to become effective as soon as practicable after such filing and such Shelf or Subsequent Shelf Registration shall be subject to the terms hereof; provided, however, the Company shall only be required to cause such Registrable Securities to be
so covered once annually after inquiry of the Holders. 
 2.4    Restrictions on Registration Rights. If
(A) during the period starting with the date sixty (60) days prior to the Company’s good faith estimate of the date of the filing of, and ending on a date one hundred and twenty (120) days after the effective date of, a Company
initiated Registration and provided that the Company has delivered written notice to the Holders prior to receipt of a Demand Registration pursuant to subsection 2.1.1 and it continues to actively

employ, in good faith, all reasonable efforts to cause the applicable Registration Statement to become effective; (B) the Holders have requested an Underwritten Registration and the Company
and the Holders are unable to obtain the commitment of underwriters to firmly underwrite the offer; or (C) in the good faith judgment of the Board such Registration would be seriously detrimental to the Company and the Board concludes as a
result that it is essential to defer the filing of such Registration Statement at such time, then in each case the Company shall furnish to such Holders a certificate signed by the Chairman of the Board, the Chief Executive Officer, the President or
Secretary of the Company stating that in the good faith judgment of the Board it would be seriously detrimental to the Company for such Registration Statement to be filed in the near future and that it is therefore essential to defer the filing of
such Registration Statement. In such event, the Company shall have the right to defer such filing for a period of not more than thirty (30) days; provided, however, that the Company shall not defer its obligation in this manner
more than once in any 12-month period. Notwithstanding anything to the contrary contained in this Agreement, no Registration shall be effected or permitted and no Registration Statement shall become effective,
with respect to any Registrable Securities held by any Holder, until after the expiration of the Founder Shares Lock-Up Period or the Private Placement Lock-Up Period,
as the case may be, the 180-day lock-up period set forth in Section 3 of the Insider Letters and, in the case of Metric only, the
540-day lock-up period set forth in Section 11 of the Insider Letters. 

ARTICLE III 
 COMPANY
PROCEDURES 
 3.1    General Procedures. If at any time on or after the date the Company consummates an initial
Business Combination the Company is required to effect the Registration of Registrable Securities, the Company shall use its best efforts to effect such Registration to permit the sale of such Registrable Securities in accordance with the intended
plan of distribution thereof, and pursuant thereto the Company shall, as expeditiously as possible: 
 3.1.1    prepare
and file with the Commission as soon as practicable a Registration Statement with respect to such Registrable Securities and use its reasonable best efforts to cause such Registration Statement to become effective and remain effective until all
Registrable Securities covered by such Registration Statement have been sold; 
 3.1.2    prepare and file with the
Commission such amendments and post-effective amendments to the Registration Statement, and such supplements to the Prospectus, as may be requested by the
majority-in-interest of the Holders with Registrable Securities registered for resale on such Registration Statement or any Underwriter of Registrable Securities or as
may be required by the rules, regulations or instructions applicable to the registration form used by the Company or by the Securities Act or rules and regulations thereunder to keep the Registration Statement effective until all Registrable
Securities covered by such Registration Statement are sold in accordance with the intended plan of distribution set forth in such Registration Statement or supplement to the Prospectus; 

3.1.3    prior to filing a Registration Statement or Prospectus, or any amendment or supplement thereto, furnish without
charge to the Underwriter(s), if any, and the Holders of Registrable Securities included in such Registration, and such Holders’ legal counsel, copies of 

  
 12 

 
such Registration Statement as proposed to be filed, each amendment and supplement to such Registration Statement (in each case including all exhibits thereto and documents incorporated by
reference therein), the Prospectus included in such Registration Statement (including each preliminary Prospectus), and such other documents as the Underwriter(s) and the Holders of Registrable Securities included in such Registration or the legal
counsel for any such Holders may request in order to facilitate the disposition of the Registrable Securities owned by such Holders; 

3.1.4    prior to any public offering of Registrable Securities, use its best efforts to (i) register or qualify the
Registrable Securities covered by the Registration Statement under such securities or “blue sky” laws of such jurisdictions in the United States as the Holders of Registrable Securities included in such Registration Statement (in light of
their intended plan of distribution) may request and (ii) take such action necessary to cause such Registrable Securities covered by the Registration Statement to be registered with or approved by such other governmental authorities as may be
necessary by virtue of the business and operations of the Company and do any and all other acts and things that may be necessary or advisable to enable the Holders of Registrable Securities included in such Registration Statement to consummate the
disposition of such Registrable Securities in such jurisdictions; provided, however, that the Company shall not be required to qualify generally to do business in any jurisdiction where it would not otherwise be required to qualify or
take any action to which it would be subject to general service of process or taxation in any such jurisdiction where it is not then otherwise so subject; 

3.1.5    cause all such Registrable Securities to be listed on each securities exchange or automated quotation system on
which similar securities issued by the Company are then listed; 
 3.1.6    provide a transfer agent or warrant agent,
as applicable, and registrar for all such Registrable Securities no later than the effective date of such Registration Statement; 

3.1.7    advise each seller of such Registrable Securities, promptly after it shall receive notice or obtain knowledge
thereof, of the issuance of any stop order by the Commission suspending the effectiveness of such Registration Statement or the initiation or threatening of any proceeding for such purpose and promptly use its reasonable best efforts to prevent the
issuance of any stop order or to obtain its withdrawal if such stop order should be issued; 
 3.1.8    at least five
(5) days prior to the filing of any Registration Statement or Prospectus or any amendment or supplement to such Registration Statement or Prospectus, furnish a copy thereof to each seller of such Registrable Securities or its counsel; 

3.1.9    notify the Holders at any time when a Prospectus relating to such Registration Statement is required to be
delivered under the Securities Act, of the happening of any event as a result of which the Prospectus included in such Registration Statement, as then in effect, includes a Misstatement, and then to correct such Misstatement as set forth in
Section 3.4 hereof; 

  
 13 

 3.1.10    permit a representative of the Holders, the Underwriter(s), if
any, and any attorney or accountant retained by such Holders or Underwriter(s) to participate, at each such person’s own expense, in the preparation of the Registration Statement, and cause the Company’s officers, directors and employees
to supply all information reasonably requested by any such representative, Underwriter, attorney or accountant in connection with the Registration; provided, however, that such representatives or Underwriter(s) enter into a
confidentiality agreement, in form and substance reasonably satisfactory to the Company, prior to the release or disclosure of any such information; 

3.1.11    obtain a “cold comfort” letter from the Company’s independent registered public accountants in
the event of an Underwritten Registration, in customary form and covering such matters of the type customarily covered by “cold comfort” letters as the managing Underwriter may reasonably request, and reasonably satisfactory to a majority-in-interest of the participating Holders; 

3.1.12    on the date the Registrable Securities are delivered for sale pursuant to such Registration, obtain an opinion,
dated such date, of counsel representing the Company for the purposes of such Registration, addressed to the participating Holders, the placement agent or sales agent, if any, and the Underwriter(s), if any, covering such legal matters with respect
to the Registration in respect of which such opinion is being given as the participating Holders, placement agent, sales agent, or Underwriter(s) may reasonably request and as are customarily included in such opinions and negative assurance letters,
and reasonably satisfactory to a majority-in-interest of the participating Holders; 

3.1.13    in the event of any Underwritten Offering, enter into and perform its obligations under an underwriting
agreement, in usual and customary form, with the managing Underwriter(s) of such offering; 
 3.1.14    make available
to its security holders, as soon as reasonably practicable, an earnings statement covering the period of at least twelve (12) months beginning with the first day of the Company’s first full calendar quarter after the effective date of the
Registration Statement which satisfies the provisions of Section 11(a) of the Securities Act and Rule 158 thereunder (or any successor rule promulgated thereafter by the Commission); 

3.1.15    if the Registration involves the resale of the Registration of Registrable Securities involving gross proceeds
in excess of $50,000,000, use its reasonable efforts to make available senior executives of the Company to participate in customary “road show” presentations that may be reasonably requested by the Underwriter(s) in any Underwritten
Offering; and 
 3.1.16    otherwise, in good faith, cooperate reasonably with, and take such customary actions as may
reasonably be requested by the participating Holders, in connection with such Registration. 
 3.2    Registration
Expenses. The Registration Expenses of all Registrations shall be borne by the Company. It is acknowledged by the Holders that the Holders shall bear all incremental selling expenses relating to the sale of Registrable Securities, such as

  
 14 

 
Underwriter(s)’ commissions and discounts, brokerage fees, Underwriter(s) marketing costs and, other than as set forth in the definition of “Registration Expenses,” all reasonable
fees and expenses of any legal counsel representing the Holders. 
 3.3    Requirements for Participation in
Underwritten Offerings. No person may participate in any Underwritten Offering for equity securities of the Company pursuant to a Registration initiated by the Company hereunder unless such person (i) agrees to sell such person’s
securities on the basis provided in any underwriting arrangements approved by the Company and (ii) completes and executes all customary questionnaires, powers of attorney, indemnities, lock-up agreements,
underwriting agreements and other customary documents as may be reasonably required under the terms of such underwriting arrangements. 

3.4    Suspension of Sales; Adverse Disclosure. Upon receipt of written notice from the Company that a Registration
Statement or Prospectus contains a Misstatement, each of the Holders shall forthwith discontinue disposition of Registrable Securities until he, she or it has received copies of a supplemented or amended Prospectus correcting the Misstatement (it
being understood that the Company hereby covenants to prepare and file such supplement or amendment as soon as practicable after the time of such notice), or until he, she or it is advised in writing by the Company that the use of the Prospectus may
be resumed. If the filing, initial effectiveness or continued use of a Registration Statement in respect of any Registration at any time would require the Company to make an Adverse Disclosure or would require the inclusion in such Registration
Statement of financial statements that are unavailable to the Company for reasons beyond the Company’s control, the Company may, upon giving prompt written notice of such action to the Holders, delay the filing or initial effectiveness of, or
suspend use of, such Registration Statement for the shortest period of time, but in no event more than thirty (30) days, determined in good faith by the Company to be necessary for such purpose. In the event the Company exercises its rights
under the preceding sentence, the Holders agree to suspend, immediately upon their receipt of the notice referred to above, their use of the Prospectus relating to any Registration in connection with any sale or offer to sell Registrable Securities.
The Company shall immediately notify the Holders of the expiration of any period during which it exercised its rights under this Section 3.4. 

3.5    Reporting Obligations. As long as any Holder shall own Registrable Securities, the Company, at all times
while it shall be a reporting company under the Exchange Act, covenants to file timely (or obtain extensions in respect thereof and file within the applicable grace period) all reports required to be filed by the Company after the date hereof
pursuant to Sections 13(a) or 15(d) of the Exchange Act and to promptly furnish the Holders with true and complete copies of all such filings. The Company further covenants that it shall take such further action as any Holder may reasonably request,
all to the extent required from time to time to enable such Holder to sell the shares of Common Stock held by such Holder without registration under the Securities Act within the limitation of the exemptions provided by Rule 144 promulgated under
the Securities Act (or any successor rule promulgated thereafter by the Commission), including providing any legal opinions. Upon the request of any Holder, the Company shall deliver to such Holder a written certification of a duly authorized
officer as to whether it has complied with such requirements. 

  
 15 

 3.6    Limitation on Registration Rights. Notwithstanding
anything herein to the contrary, (i) Metric may not exercise its rights under Sections 2.1 and 2.2 hereunder after five (5) and seven (7) years, respectively, from the effective date of the Company’s registration
statement on Form S-1 (File No. 33-[●]) and (ii) Metric may not exercise its rights under Section 2.1 more than one time. 

ARTICLE IV 
 INDEMNIFICATION
AND CONTRIBUTION 
 4.1    Indemnification. 

4.1.1    The Company agrees to indemnify, to the extent permitted by law, each Holder of Registrable Securities, its
officers, directors, employees, agents and each person who controls such Holder (within the meaning of the Securities Act) against all losses, claims, damages, liabilities and expenses (including, without limitation, attorneys’ fees) resulting
from any untrue or alleged untrue statement of material fact contained in any 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 not misleading, except insofar as the same are caused by or contained in any information furnished in writing to the Company by such Holder expressly for use therein. The Company shall
indemnify the Underwriter(s), their officers, employees and directors and each person who controls such Underwriter(s) (within the meaning of the Securities Act) to the same extent as provided in the foregoing with respect to the indemnification of
the Holder. 
 4.1.2    In connection with any Registration Statement in which a Holder of Registrable Securities is
participating, such Holder shall furnish to the Company in writing such information and affidavits as the Company reasonably requests for use in connection with any such Registration Statement or Prospectus and, to the extent permitted by law, shall
indemnify the Company, its directors, officers and agents and each person who controls the Company (within the meaning of the Securities Act) against any losses, claims, damages, liabilities and expenses (including, without limitation, reasonable
attorneys’ fees) resulting from any untrue statement of material fact contained in the Registration Statement, Prospectus or preliminary Prospectus or any amendment thereof or supplement thereto or any omission of a material fact required to be
stated therein or necessary to make the statements therein not misleading, but only to the extent that such untrue statement or omission is contained in any information or affidavit so furnished in writing by such Holder expressly for use therein;
provided, however, that the obligation to indemnify under this Section 4.1.2 shall be several, not joint and several, among such Holders of Registrable Securities, and the total indemnification liability of
each such Holder of Registrable Securities under this Section 4.1.2 shall be in proportion to and limited to the net proceeds received by such Holder from the sale of Registrable Securities pursuant to such Registration
Statement. The Holders of Registrable Securities shall indemnify the Underwriter(s), their officers, employees and directors and each person who controls such Underwriter(s) (within the meaning of the Securities Act) to the same extent as provided
in the foregoing with respect to indemnification of the Company. 

  
 16 

 4.1.3    Any person entitled to indemnification herein shall
(i) give prompt written notice to the indemnifying party of any claim with respect to which it seeks indemnification (provided that the failure to give prompt notice shall not impair any person’s right to indemnification hereunder to the
extent such failure has not materially prejudiced the indemnifying party) and (ii) unless in such indemnified party’s reasonable judgment a conflict of interest between such indemnified and indemnifying parties may exist with respect to
such claim, 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 (but such consent shall not be unreasonably withheld). An indemnifying party who is not entitled to, or 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 any indemnified party a conflict of interest may exist 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. 
 4.1.4    The indemnification provided for
under this 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 or controlling person of such indemnified party and shall survive the transfer of
securities. The Company and each Holder of Registrable Securities participating in an offering also agrees to make such provisions as are reasonably requested by any indemnified party for contribution to such party in the event the Company’s or
such Holder’s indemnification is unavailable for any reason. 
 4.2    Contribution. 

4.2.1    If the indemnification provided under Section 4.1 hereof from the indemnifying party is
unavailable or insufficient to hold harmless an indemnified party in respect of any losses, claims, damages, liabilities and expenses referred to herein, then the indemnifying party, in lieu of indemnifying the indemnified party, shall contribute to
the amount paid or payable by the indemnified party as a result of such losses, claims, damages, liabilities and expenses in such proportion as is appropriate to reflect the relative fault of the indemnifying party and the indemnified party, as well
as any other relevant equitable considerations. The relative fault of the indemnifying party and indemnified party shall be determined by reference to, among other things, whether any action in question, including any untrue or alleged untrue
statement of a material fact or omission or alleged omission to state a material fact, was made by, or relates to information supplied by, 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; provided, however, that the liability of any Holder under this subsection 4.2.1 shall be limited to the amount of the net
proceeds received by such Holder in such offering giving rise to such liability. 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 subsections 4.1.1, 4.1.2 and 4.1.3 above, any legal or other fees, charges or expenses reasonably incurred by such party in connection with any investigation or 

  
 17 

 
proceeding. The parties hereto agree that it would not be just and equitable if contribution pursuant to this subsection 4.2.1 were determined by pro rata allocation or by any other method
of allocation, which does not take account of the equitable considerations referred to in this subsection 4.2.1. 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 subsection 4.2.1 from any person who was not guilty of such fraudulent misrepresentation. 

ARTICLE V 
 STOCKHOLDER
RIGHTS 
 5.1    Subject to the terms and conditions of this Agreement, at any time and from time to time on or after
the date that the Company consummates an initial Business Combination and for so long as the Sponsor (and any of its Permitted Transferees) holds in the aggregate at least fifty percent (50%) of the number of Founder Shares held by the Sponsor
immediately prior to closing of the Company’s initial public offering and after any forfeiture of its Founder Shares: 

5.1.1    The Sponsor shall have the right, but not the obligation, to designate three (3) individuals to be appointed
or nominated, as the case may be, for election to the Board (including any successor, each, a “Nominee”) by giving written notice to the Company on or before the time such information is reasonably requested by the Board or the
Nominating Committee of the Board, as applicable, for inclusion in a proxy statement for a meeting of stockholders. 

5.1.2    The Company will, as promptly as practicable, use its best efforts to take all necessary and desirable actions
(including, without limitation, calling special meetings of the Board and the stockholders and recommending, supporting and soliciting proxies) so that there are three (3) Sponsor Directors serving on the Board at all times during which the
nomination rights provided in this Section 5.1 are applicable. 
 5.1.3    The Company shall,
to the fullest extent permitted by applicable law, use its best efforts to take all actions necessary to ensure that: (i) each Nominee is included in the Board’s slate of nominees to the stockholders of the Company for each election of
Directors; and (ii) each Nominee is included in the proxy statement prepared by management of the Company in connection with soliciting proxies for every meeting of the stockholders of the Company called with respect to the election of members
of the Board, and at every adjournment or postponement thereof, and on every action or approval by written consent of the stockholders of the Company or the Board with respect to the election of members of the Board. 

5.1.4    If a vacancy occurs because of the death, disability, disqualification, resignation, or removal of a Sponsor
Director or for any other reason during the period in which rights provided in this Section 5.1 are applicable, the Sponsor shall be entitled to designate such person’s successor, and the Company will, as promptly as
practicable following such designation, use its best efforts to take all necessary and desirable actions, to the fullest extent permitted by law, within its control such that such vacancy shall be filled with such successor Nominee. 

  
 18 

 5.1.5    If a Nominee is not elected because of such Nominee’s
death, disability, disqualification, withdrawal as a nominee or for any other reason, the Sponsor shall be entitled to designate promptly another Nominee and the Company will take all necessary and desirable actions within its control such that the
director position for which such Nominee was nominated shall not be filled pending such designation or the size of the Board shall be increased by one and such vacancy shall be filled with such successor Nominee as promptly as practicable following
such designation. 
 5.1.6    As promptly as reasonably practicable following the request of any Sponsor Director, the
Company shall enter into an indemnification agreement with such Sponsor Director, in the form entered into with the other members of the Board. The Company shall pay the reasonable, documented out-of-pocket expenses incurred by the Sponsor Director in connection with his or her services provided to or on behalf of the Company, including attending meetings or events attended explicitly on behalf of
the Company at the Company’s request. 
 5.1.7    The Company shall (i) purchase directors’ and
officers’ liability insurance in an amount determined by the Board to be reasonable and customary and (ii) for so long as a Sponsor Director serves as a Director of the Company, maintain such coverage with respect to such Sponsor Director;
provided that upon removal or resignation of such Sponsor Director for any reason, the Company shall take all actions reasonably necessary to extend such directors’ and officers’ liability insurance coverage for a period of not less than
six (6) years from any such event in respect of any act or omission occurring at or prior to such event. 

5.1.8    For so long as a Sponsor Director serves as a Director of the Company, the Company shall not amend, alter or
repeal any right to indemnification or exculpation covering or benefiting any Director nominated pursuant to this Agreement as and to the extent consistent with applicable law, whether such right is contained in the Company’s amended and
restated certificate of incorporation or amended and restated bylaws, each as amended, or another document (except to the extent such amendment or alteration permits the Company to provide broader indemnification or exculpation rights on a
retroactive basis than permitted prior thereto). 
 5.1.9    Each Nominee may, but does not need to qualify as
“independent” pursuant to listing standards of the New York Stock Exchange (or such other national securities exchange upon which the Company’s securities are then listed). 

5.1.10    Any Nominee will be subject to the Company’s customary due diligence process, including its review of a
completed questionnaire and a background check. Based on the foregoing, the Company may object to any Nominee provided (a) it does so in good faith, and (b) such objection is based upon any of the following: (i) such Nominee was
convicted in a criminal proceeding or is a named subject of a pending criminal proceeding (excluding traffic violations and other minor offenses), (ii) such Nominee was the subject of any order, judgment, or decree not subsequently reversed,
suspended or vacated of any court of competent jurisdiction, permanently or temporarily enjoining such proposed director from, or otherwise limiting, the following activities: (A) engaging in any type of business practice or (B) engaging
in any activity in connection with the purchase or sale of any security or in connection with any violation of federal or state securities laws, (iii) such Nominee was the subject of any order, judgment or decree, not subsequently reversed,
suspended or vacated, of any federal or state authority 

  
 19 

 
barring, suspending or otherwise limiting for more than 60 days the right of such person to engage in any activity described in clause (ii)(B), or to be associated with persons engaged in such
activity, (iv) such proposed director was found by a court of competent jurisdiction in a civil action or by the Commission to have violated any federal or state securities law, and the judgment in such civil action or finding by the Commission
has not been subsequently reversed, suspended or vacated, or (v) such proposed director was the subject of, or a party to any federal or state judicial or administrative order, judgment, decree, or finding, not subsequently reversed, suspended
or vacated, relating to a violation of any federal or state securities laws or regulations. In the event the Board reasonably finds the Nominee to be unsuitable based upon one or more of the foregoing clauses (i) through (v) and reasonably
objects to the identified director, the Sponsor shall be entitled to propose a different nominee to the Board within thirty (30) calendar days of the Company’s notice to the Sponsor of its objection to the Nominee and such replacement
Nominee shall be subject to the review process outlined above. 
 5.1.11    The Company shall take all necessary action
to cause a Sponsor Director chosen by the Sponsor to be elected to the board of directors (or similar governing body) of each material operating subsidiary of the Company to the extent requested by the Sponsor. Such Sponsor Director shall have the
right to attend (in person or remotely) any meetings of the board of directors (or similar governing body or committee thereof) of each subsidiary of the Company.

the Company in whole or in part. 

  
 20 

 6.2.2    Prior to the expiration of the Founder Shares Lock-up Period or the Private Placement Lock-up Period, as the case may be, no Holder may assign or delegate such Holder’s rights, duties or obligations under this
Agreement, in whole or in part, except in connection with a transfer of Registrable Securities by such Holder to a Permitted Transferee, but only if such Permitted Transferee agrees to be bound by the transfer restrictions set forth in this
Agreement, the Insider Letters, and in the Warrant Purchase Agreement (if the Registrable Securities being transferred are Private Placements Warrants), as the case may be, or in any other applicable agreement or instrument. 

6.2.3    This Agreement and the provisions hereof shall be binding upon and shall inure to the benefit of each of the
parties and its successors and the permitted assigns of the Holders, which shall include Permitted Transferees.

expressly set forth in this Agreement and Section 6.2 hereof. 
 6.2.5    No assignment by any
party hereto of such party’s rights, duties and obligations hereunder shall be binding upon or obligate the Company unless and until the Company shall have received (i) written notice of such assignment as provided in
Section 6.1 hereof and (ii) the written agreement of the assignee, in a form reasonably satisfactory to the Company, to be bound by the terms and provisions of this Agreement (which may be accomplished by an addendum

6.3    Counterparts. This Agreement may be executed in multiple counterparts (including facsimile or PDF

REGARD TO THE CONFLICT OF LAW PROVISIONS OF SUCH JURISDICTION. 

  
 21 

 6.5    Waiver of Trial by Jury. EACH PARTY HEREBY IRREVOCABLY AND
UNCONDITIONALLY WAIVES THE RIGHT TO A TRIAL BY JURY IN ANY ACTION, SUIT, COUNTERCLAIM OR OTHER PROCEEDING (WHETHER BASED ON CONTRACT, TORT OR OTHERWISE) ARISING OUT OF, CONNECTED WITH OR RELATING TO THIS AGREEMENT, THE TRANSACTIONS CONTEMPLATED
HEREBY, OR THE ACTIONS OF THE SPONSOR IN THE NEGOTIATION, ADMINISTRATION, PERFORMANCE OR ENFORCEMENT HEREOF. 

6.6    Amendments and Modifications. Upon the written consent of the Company and the Holders of at least a majority-in-interest of the Registrable Securities at the time in question, compliance with any of the provisions, covenants and conditions set forth in this Agreement may be
waived, or any of such provisions, covenants or conditions may be amended or modified; provided, however, that notwithstanding the foregoing, any amendment hereto or waiver hereof that adversely affects one Holder, solely in his, her
or its capacity as a holder of shares of the capital stock of the Company, in a manner that is materially different from the other Holders (in such capacity) shall require the consent of the Holder so affected. No course of dealing between any
Holder or the Company and any other party hereto or any failure or delay on the part of a Holder or the Company in exercising any rights or remedies under this Agreement shall operate as a waiver of any rights or remedies of any Holder or the
Company. No single or partial exercise of any rights or remedies under this Agreement by a party shall operate as a waiver or preclude the exercise of any other rights or remedies hereunder or thereunder by such party. 

6.7    Other Registration Rights. The Company represents and warrants that no person, other than a Holder of
Registrable Securities and the Forward Purchaser, has any right to require the Company to register the offer, sale, or resale of any securities of the Company for sale or to include such securities of the Company in any Registration filed by the
Company for the sale of securities for its own account or for the account of any other person. Further, the Company represents and warrants that, other than the Forward Purchase Agreement, this Agreement supersedes any other registration rights

PRIVATE PLACEMENT WARRANTS PURCHASE AGREEMENT 

THIS PRIVATE PLACEMENT WARRANTS PURCHASE AGREEMENT, effective as of [•], 2021 (as it may from time to time be amended, this
“Agreement”), is entered into by and between First Light Acquisition Group, Inc., a Delaware corporation (the “Company”), each of the undersigned series 1 through 15 of First Light Acquisition Group, LLC, a Delaware
series limited liability company (such 15 series collectively, the “Sponsor”) and Metric Finance Holdings I, LLC, a Delaware limited liability company (“Metric”, together with the Sponsor, the
“Purchasers”). 
 WHEREAS: 

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-half 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
“Registration Statement”), under the Securities Act of 1933, as amended (the “Securities Act”); 
 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 under the column “Private Placement Warrants” 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 to purchase one Share at an exercise price of $11.50 per Share. 
 NOW THEREFORE, in
consideration of the mutual promises contained in this Agreement and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties to this Agreement hereby, intending legally to be bound, agree as
follows: 
 AGREEMENT 

Section 1. Authorization, Purchase and Sale; Terms of the Private Placement Warrants. 

A. Authorization of the Private Placement Warrants. The Company has duly authorized the issuance and sale of the Private Placement
Warrants to the Purchasers. 
 B. Purchase and Sale of the Private Placement Warrants. 

(i) On the date of the consummation of the Public Offering or on such earlier time and date as may be mutually agreed upon by the Purchasers
and the Company (the “Initial Closing Date”), the Company shall issue and sell to each Purchaser, and each Purchaser shall purchase from the Company, the Private Placement Warrants at a price of $1.50 per warrant for an aggregate
purchase price set forth opposite such Purchaser’s name under the column “Private Placement Warrants Purchase Price” on Schedule I hereto (the “Purchase Price”), which shall be paid by wire transfer of
immediately available funds to an account designated by the Company, at least one business day prior to the Initial Closing Date in accordance with the Company’s wiring instructions; provided, however, that the Purchase Price shall be
reimbursed to the relevant Purchaser if the Initial Closing Date does not occur on the next business day following such wire payment. On the Initial Closing Date, following the payment by each Purchaser of the 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. 

 (ii) On the date of the consummation of each closing (if any) of the over-allotment option
in connection with the Public Offering or on such earlier time and date as may be mutually agreed upon by the relevant Purchaser and the Company (each such date, an “Over-allotment Closing Date”, and, each Over-allotment Closing
Date (if any) together with the Initial Closing Date, being sometimes referred to herein as a “Closing Date”), the Company shall issue and sell to the Purchasers, and the Purchasers shall purchase from the Company, an aggregate of
up to 3,397,155 Private Placement Warrants (for each Purchaser, up to the number of warrants set forth opposite such Purchaser’s name under the column “Over-Allotment” on Schedule I hereto), in the same proportion as the
portion of the over-allotment option that is then so exercised, at a price of $1.50 per warrant for an aggregate purchase price of up to $5,095,732.50 (for each Purchaser, for an aggregate purchase price up to the amount set forth opposite such
Purchaser’s name under the column “Over-Allotment Purchase Price” on Schedule I hereto) if the over-allotment option in connection with the Public Offering is exercised in full (the “Over-allotment Purchase
Price”), which shall be paid by wire transfer of immediately available funds to the Company at least one business day prior to such Over-allotment Closing Date in accordance with the Company’s wiring instructions; provided, however,
that the Over-allotment Purchase Price shall be reimbursed to the relevant Purchaser if such Over-allotment Closing Date does not occur on the next business day following such wire payment. On the Over-allotment Closing Date, following the payment
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. 
 C. Terms of the
Private Placement Warrants. 
 (i) Each Private Placement Warrant shall have the terms set forth in a Warrant Agreement to be entered
into by the Company and a warrant agent, in connection with the Public Offering (the “Warrant Agreement”). 
 (ii) On or
prior to the time of the closing of the Public Offering, the Company and the Purchasers shall enter into a registration and stockholders rights agreement (the “Registration and Stockholders Rights Agreement”) pursuant to which the
Company will grant certain registration rights to the Purchasers relating to the Private Placement Warrants and the Shares underlying the Private Placement Warrants. 

  
 2 

 Section 2. Representations and Warranties of the Company. As a material inducement
to the Purchaser to enter into this Agreement and purchase the Private Placement Warrants, the Company hereby represents and warrants to each Purchaser (which representations and warranties shall survive each Closing Date) that: 

A. Organization and Corporate Power. The Company is a corporation duly incorporated, validly existing and in good standing under the
laws of the State of Delaware 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 and the Warrant Agreement. 

B. Authorization; No Breach. 

(i) The execution, delivery and performance of this Agreement and the Private Placement Warrants have been duly authorized by the Company as of
the Initial Closing Date. This Agreement constitutes the valid and binding obligation of the Company, enforceable in accordance with its terms. Upon issuance in accordance with, and payment pursuant to, the terms of the Warrant Agreement and this
Agreement, the Private Placement Warrants will constitute valid and binding obligations of the Company, enforceable in accordance with their terms as of each Closing Date. 

(ii) The execution and delivery by the Company of this Agreement and the Private Placement Warrants, the issuance and sale of the Private
Placement Warrants, the issuance of the Shares upon exercise of the Private Placement Warrants and the fulfillment of, and compliance with, the respective terms hereof and thereof by the Company, do not and will not as of each Closing Date
(a) conflict with or result in a breach of the terms, conditions or provisions of, (b) constitute a default under, (c) result in the creation of any lien, security interest, charge or encumbrance upon the Company’s capital stock
or assets under, (d) result in a violation of, or (e) require any authorization, consent, approval, exemption or other action by or notice or declaration to, or filing with, any court or administrative or governmental body or agency
pursuant to the certificate of incorporation of the Company or the Bylaws of the Company (in effect on the date hereof or as may be amended prior to completion of the contemplated Public Offering), or any material law, statute, rule or regulation to
which the Company is subject, or any agreement, order, judgment or decree to which the Company is subject, except for any filings required after the date hereof under federal or state securities laws. 

C. Title to Securities. Upon issuance in accordance with, and payment pursuant to, the terms hereof and the Warrant Agreement, the
Shares issuable upon exercise of the Private Placement Warrants will be duly and validly issued, fully paid and nonassessable. Upon issuance in accordance with, and payment pursuant to, the terms hereof and the Warrant Agreement, each Purchaser will
have good title to the Private Placement Warrants it has purchased and the Shares issuable upon exercise of such Private Placement Warrants, free and clear of all liens, claims and encumbrances of any kind, other than (i) transfer restrictions
hereunder and under the other agreements contemplated hereby, (ii) transfer restrictions under federal and state securities laws, and (iii) liens, claims or encumbrances imposed due to the actions of such Purchaser. 

D. Governmental Consents. No permit, consent, approval or authorization of, or declaration to or filing with, any governmental
authority 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
shareholders of 20% or more of its outstanding securities, has experienced a disqualifying event as enumerated pursuant to Rule 506(d) of Regulation D under the Securities Act. 

  
 3 

 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
correct at and as of such Closing Date as though then made. 
 B. Performance. The Company shall have performed and complied with all
agreements, obligations and conditions contained in this Agreement that are required to be performed or complied with by it on or before such Closing Date.

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
warrant agent on terms satisfactory to each Purchaser. 
 E. Registration and Stockholders Rights Agreement. The Company shall have
entered into a Registration and Stockholders Rights Agreement with the Purchasers on terms satisfactory to each Purchaser.

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

 6

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
