Re:          
Initial Public Offering

 

Ladies and Gentlemen:

 

This letter (this “Letter Agreement”)
is being delivered to you in accordance with the Underwriting Agreement (the “Underwriting Agreement”)
entered into by and among Research Alliance Corp. II, a Delaware corporation (the “Company”), and Jefferies
LLC as representative (the “Representative”) of the several underwriters (each, an “Underwriter”
and collectively, the “Underwriters”), relating to an underwritten initial public offering (the “Public
Offering”), of up to 14,950,000 of the Company’s Class A common stock, par value $0.0001 per share (the
 “Class A Common Stock” or the “Securities”). The Securities will be sold
in the Public Offering pursuant to a registration statement on Form S-1 and prospectus (the “Prospectus”)
filed by the Company with the U.S. Securities and Exchange Commission (the “Commission”) and the Company
has applied to have the Securities listed on the Nasdaq Capital Market. Certain capitalized terms used herein are defined in paragraph
11 hereof.

 

In order to induce the Company and the Underwriters
to enter into the Underwriting Agreement and to proceed with the Public Offering and for other good and valuable consideration,
the receipt and sufficiency of which are hereby acknowledged, each of Research Alliance Holdings II LLC (the “Sponsor”)
and the undersigned individuals, each of whom is a member of the Company’s board of directors and/or management team (each
of the undersigned individuals, an “Insider” and collectively, the “Insiders”),
hereby agrees with the Company as follows:

 

		1.	The Sponsor and each Insider agrees that if the Company
seeks stockholder approval of a proposed Business Combination, then in connection with such proposed Business Combination, it,
he or she shall (i) vote any shares of Common Stock (as defined below) owned by it, him or her in favor of any proposed Business
Combination and (ii) not redeem any shares of Common Stock owned by it, him or her in connection with such stockholder approval. 
If the Company seeks to consummate a proposed Business Combination by engaging in a tender offer, the Sponsor and each Insider
agrees that it, he or she will not sell or tender any shares of Common Stock owned by it, him or her in connection therewith.

 

		2.	The Sponsor and each Insider hereby agrees that in the
event that the Company fails to consummate a Business Combination within 24 months from the closing of the Public Offering, or
such later period approved by the Company’s stockholders in accordance with the Company’s amended and restated certificate
of incorporation (as it may be amended from time to time, the “Charter”), the Sponsor and each Insider
shall take all reasonable steps to cause the Company to (i) cease all operations except for the purpose of winding up, (ii) as
promptly as reasonably possible but not more than ten business days thereafter, redeem 100% of the shares of Class A Common
Stock sold as part of the Securities in the Public Offering (the “Offering Shares”), at a per-share
price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account (as defined below), including interest
earned on the funds held in the Trust Account and not previously released to the Company to pay its taxes (less taxes payable
and up to $100,000 of interest to pay dissolution expenses), divided by the number of then outstanding Offering Shares, which
redemption will completely extinguish all Public Stockholders’ (as defined below) rights as stockholders (including the
right to receive further liquidating distributions, if any), and (iii) as promptly as reasonably possible following such
redemption, subject to the approval of the Company’s remaining stockholders and the Company’s board of directors,
liquidate and dissolve, subject in each case to the Company’s obligations under Delaware law to provide for claims of creditors
and other requirements of applicable law. The Sponsor and each Insider agrees to not propose any amendment to the Charter to modify
the substance or timing of the Company’s obligation to redeem 100% of the Offering Shares if the Company does not complete
a Business Combination within the required time period set forth in the Charter or with respect to any other material provisions
relating to stockholders’ rights or pre-initial business combination activity, unless the Company provides its Public Stockholders
with the opportunity to redeem their Offering Shares upon approval of any such amendment at a per-share price, payable in cash,
equal to the aggregate amount then on deposit in the Trust Account, including interest earned on the funds held in the Trust Account
and not previously released to the Company to pay its taxes, divided by the number of then outstanding Offering Shares.

 

     

     

    

 

The Sponsor and each Insider acknowledges that it, he
or she has no right, title, interest or claim of any kind in or to any monies held in the Trust Account or any other asset of the
Company as a result of any liquidation of the Company with respect to the Founder Shares (as defined below) held by it, him or
her. The Sponsor and each Insider hereby further waives, with respect to any shares of Common Stock held by it, him or her, if
any, any redemption rights it, he or she may have in connection with (A) the consummation of a Business Combination, including,
without limitation, any such rights available in the context of a stockholder vote to approve such Business Combination, or (B) a
stockholder vote to approve an amendment to the Charter to modify the substance or timing of the Company’s obligation to
redeem 100% of the Offering Shares if the Company has not consummated a Business Combination within the time period set forth in
the Charter or with respect to any other material provisions relating to stockholders’ rights or pre-initial business combination
activity or in the context of a tender offer made by the Company to purchase Offering Shares (although the Sponsor, the Insiders
and their respective affiliates shall be entitled to redemption and liquidation rights with respect to any Offering Shares it or
they hold if the Company fails to consummate a Business Combination within the time period set forth in the Charter).

 

		3.	During the period commencing on the effective date of
the Underwriting Agreement and ending 180 days after such date, the Sponsor and each Insider shall not, without the prior written
consent of the Representative, (i) sell, offer to sell, contract or agree to sell, hypothecate, pledge, grant any option
to purchase or otherwise dispose of or agree to dispose of, directly or indirectly, or establish or increase a put equivalent
position or liquidate or decrease a call equivalent position within the meaning of Section 16 of the Securities Exchange
Act of 1934, as amended (the “Exchange Act”), and the rules and regulations of the Commission promulgated
thereunder, with respect to, any shares of Common Stock (including, but not limited to, Founder Shares), or any securities convertible
into, or exercisable, or exchangeable for, shares of Common Stock owned by it, him or her, (ii) enter into any swap or other
arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of any shares of Common
Stock (including, but not limited to, Founder Shares), or any securities convertible into, or exercisable, or exchangeable for,
shares of Common Stock owned by it, him or her, whether any such transaction is to be settled by delivery of such securities,
in cash or otherwise, or (iii) publicly announce any intention to effect any transaction specified in clause (i) or
(ii); provided, however, that the foregoing does not apply to the forfeiture of any Founder Shares pursuant to their terms or
any transfer of Founder Shares to any current or future independent director of the company (as long as such current or future
independent director transferee is subject to this Letter Agreement or executes an agreement substantially identical to the terms
of this Letter Agreement, as applicable to directors and officers at the time of such transfer; and as long as, to the extent
any Section 16 reporting obligation is triggered as a result of such transfer, any related Section 16 filing includes
a practical explanation as to the nature of the transfer). Each of the Insiders and the Sponsor acknowledges and agrees that,
prior to the effective date of any release or waiver, of the restrictions set forth in this paragraph 3 or paragraph 7 below,
the Company shall announce the impending release or waiver by press release through a major news service at least two business
days before the effective date of the release or waiver. Any release or waiver granted shall only be effective two business days
after the publication date of such press release. The provisions of this paragraph will not apply if the release or waiver is
effected solely to permit a transfer not for consideration and the transferee has agreed in writing to be bound by the same terms
described in this Letter Agreement to the extent and for the duration that such terms remain in effect at the time of the transfer.
Notwithstanding the foregoing, nothing in this Section 3 will prohibit (1)  the issuance and sale of Private Placement
Shares (as defined below), (2) the issuance and sale of any Securities in the Public Offering, including any Securities issued
and sold to cover over-allotments, if any, (3) the registration with the SEC pursuant to an agreement to be entered into
concurrently with the execution of this Agreement, the resale of the Private Placement Shares and the Founder Shares and (4) issuance
of securities in connection with a Business Combination.

 

     

     

    

 

		4.	In the event of the liquidation of the Trust Account
upon the failure of the Company to consummate its initial Business Combination within the time period set forth in the Charter,
the Sponsor (the “Indemnitor”) agrees to indemnify and hold harmless the Company against any and all
loss, liability, claim, damage and expense whatsoever (including, but not limited to, any and all legal or other expenses reasonably
incurred in investigating, preparing or defending against any litigation, whether pending or threatened) to which the Company
may become subject as a result of any claim by (i) any third party for services rendered or products sold to the Company
or (ii) any prospective target business with which the Company has entered into a written letter of intent, confidentiality
or other similar agreement or Business Combination agreement (a “Target”); provided, however,
that such indemnification of the Company by the Indemnitor (x) shall apply only to the extent necessary to ensure that such
claims by a third party or a Target do not reduce the amount of funds in the Trust Account to below the lesser of (i) $10.00
per Offering Share and (ii) the actual amount per Offering Share held in the Trust Account as of the date of the liquidation
of the Trust Account, if less than $10.00 per Offering Share is then held in the Trust Account due to reductions in the value
of the trust assets, less taxes payable, (y) shall not apply to any claims by a third party or a Target which executed a
waiver of any and all rights to the monies held in the Trust Account (whether or not such waiver is enforceable) and (z) shall
not apply to any claims under the Company’s indemnity of the Underwriters against certain liabilities, including liabilities
under the Securities Act of 1933, as amended. The Indemnitor shall have the right to defend against any such claim with counsel
of its choice reasonably satisfactory to the Company if, within 15 days following written receipt of notice of the claim to the
Indemnitor, the Indemnitor notifies the Company in writing that it shall undertake such defense.

 

		5.	To the extent that the Underwriters do not exercise their
over-allotment option to purchase up to an additional 1,950,000 Securities within 45 days from the date of the Prospectus (and
as further described in the Prospectus), the Sponsor agrees to forfeit, at no cost, a number of Founder Shares in the aggregate
equal to [375,000] multiplied by a fraction, (i) the numerator of which is 1,950,000 minus the number of Securities purchased
by the Underwriters upon the exercise of their over-allotment option, and (ii) the denominator of which is 1,950,000. The
forfeiture will be adjusted to the extent that the over-allotment option is not exercised in full by the Underwriters so that
the Founder Shares will represent an aggregate of 20.0% of the Company’s issued and outstanding shares of Class A Common
Stock after the Public Offering (not including the Private Placement Shares (as defined below)). The Sponsor further agrees that
to the extent that the size of the Public Offering is increased or decreased, the Company will purchase or sell Securities or
effect a share repurchase or share capitalization, as applicable, immediately prior to the consummation of the Public Offering
in such amount as to maintain the ownership of the initial shareholders prior to the Public Offering at 20.0% of its issued and
outstanding Capital Shares upon the consummation of the Public Offering. In connection with such increase or decrease in the size
of the Public Offering, then (A) the references to 1,950,000 in the numerator and denominator of the formula in the first
sentence of this paragraph shall be changed to a number equal to 15% of the number of Public Shares included in the Securities
issued in the Public Offering and (B) the reference to [375,000] in the formula set forth in the first sentence of this paragraph
shall be adjusted to such number of Founder Shares that the Sponsor would have to surrender to the Company in order for the initial
shareholders to hold an aggregate of 20.0% of the Company’s issued and outstanding shares of Class A Common Stock after
the Public Offering (not including Private Placement Shares).

 

     

     

    

 

		6.	The Sponsor and each Insider hereby agrees and acknowledges
that: (i) the Underwriters and the Company would be irreparably injured in the event of a breach by such Sponsor or an Insider
of its, his or her obligations under paragraphs 1, 2, 3, 4, 5, 7(a), and 7(b), as applicable, of this Letter Agreement (ii) monetary
damages may not be an adequate remedy for such breach and (iii) the non-breaching party shall be entitled to injunctive relief,
in addition to any other remedy that such party may have in law or in equity, in the event of such breach.

 

		7.	(a)           
The Sponsor and each Insider agrees that it, he or she shall not Transfer any Founder Shares (or any shares of Class A
Common Stock issuable upon conversion thereof)  until the earlier of (A) one year after the completion of the Company’s
initial Business Combination and (B) subsequent to the Business Combination, (x) if the closing price of the Class A
Common Stock equals or exceeds $12.00 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations
and the like) for any 20 trading days within any 30-trading day period commencing at least 150 days after the Company’s
initial Business Combination or (y) the date on which the Company completes a liquidation, merger, capital stock exchange,
reorganization or other similar transaction that results in all of the Company’s stockholders having the right to exchange
their shares of Class A Common Stock for cash, securities or other property (the “Founder Shares Lock-up Period”).

 

			(b)           The
Sponsor and each Insider agrees that it, he or she shall not Transfer any Private Placement Shares, until 30 days after the completion
of a Business Combination (the “Private Placement Shares Lock-up Period”, together with the Founder
Shares Lock-up Period, the “Lock-up Periods”).

 

			(c)           
Notwithstanding the provisions set forth in paragraphs 7(a) and (b), Transfers of the Founder Shares, Private Placement
Shares or the Founder Shares that are held by the Sponsor, any Insider or any of their permitted transferees (that have complied
with this paragraph 7(c)), are permitted (a) to the Company’s officers or directors, any affiliates or family members
of any of the Company’s officers or directors, to the Sponsor, any members or partners of the Sponsor or their affiliates,
or any affiliates of the Sponsor; (b) in the case of an individual, by gift to a member of such individual’s immediate
family or to a trust, the beneficiary of which is a member of such individual’s immediate family, an affiliate of such individual
or to a charitable organization; (c) in the case of an individual, by virtue of laws of descent and distribution upon death
of such individual; (d) in the case of an individual, pursuant to a qualified domestic relations order; (e) by private
sales or transfers made in connection with any forward purchase agreement or similar arrangement or in connection with the consummation
of an initial Business Combination at prices no greater than the price at which the securities were originally purchased; (f) by
virtue of the laws of the State of Delaware or the Sponsor’s limited liability company agreement upon dissolution of the
Sponsor; (g) to the Company for no value for cancellation in connection with the consummation of a Business Combination;
(h) in the event of the Company’s liquidation prior to the consummation of a Business Combination; or (i) in the
event of the Company’s liquidation, merger, capital stock exchange or other similar transaction which results in all of
the Company’s stockholders having the right to exchange their shares of Class A Common Stock for cash, securities or
other property subsequent to the Company’s completion of an initial Business Combination; provided, however,
that in the case of clauses (a) through (f), these permitted transferees must enter into a written agreement with the Company
agreeing to be bound by the transfer restrictions herein and the other restrictions contained in this Agreement (including provisions
relating to voting, the Trust Account and liquidating distributions).

 

     

     

    

 

		8.	The Sponsor and each Insider represents and warrants
that it, he or she has never been suspended or expelled from membership in any securities or commodities exchange or association
or had a securities or commodities license or registration denied, suspended or revoked. Each Insider’s biographical information
furnished to the Company (including any such information included in the Prospectus) is true and accurate in all respects and
does not omit any material information with respect to the Insider’s background. The Sponsor and each Insider’s questionnaire
furnished to the Company is true and accurate in all respects. The Sponsor and each Insider represents and warrants that: it,
he or she is not subject to or a respondent in any legal action for, any injunction, cease-and-desist order or order or stipulation
to desist or refrain from any act or practice relating to the offering of securities in any jurisdiction; it, he or she has never
been convicted of, or pleaded guilty to, any crime (i) involving fraud, (ii) relating to any financial transaction or
handling of funds of another person, or (iii) pertaining to any dealings in any securities and it, he or she is not currently
a defendant in any such criminal proceeding.

 

		9.	Except as disclosed in the Prospectus, neither the Sponsor
nor any officer, nor any affiliate of the Sponsor or any officer, nor any director of the Company, shall receive from the Company
any finder’s fee, reimbursement, consulting fee, non-cash payments, monies in respect of any repayment of a loan or other
compensation prior to, or in connection with any services rendered in order to effectuate, the consummation of the Company’s
initial Business Combination (regardless of the type of transaction that it is), other than the following, none of which will
be made from the proceeds held in the Trust Account prior to the completion of the initial Business Combination: repayment of
a loan and advances up to an aggregate of $300,000 made to the Company by the Sponsor; reimbursement for any reasonable out-of-pocket
expenses related to identifying, investigating, negotiating and completing an initial Business Combination, and repayment of loans,
if any, and on such terms as to be determined by the Company from time to time, made by the Sponsor or an affiliate of the Sponsor
or any of the Company’s officers or directors to finance transaction costs in connection with an intended initial Business
Combination, provided, that, if the Company does not consummate an initial Business Combination, a portion of the working capital
held outside the Trust Account may be used by the Company to repay such loaned amounts so long as no proceeds from the Trust Account
are used for such repayment. Up to $1,500,000 of such loans may be convertible into shares at a price of $10.00 per share at the
option of the lender. Such shares would be identical to the Private Placement Shares.

 

		10.	The Sponsor and each Insider has full right and power,
without violating any agreement to which it is bound (including, without limitation, any non-competition or non-solicitation agreement
with any employer or former employer), to enter into this Letter Agreement and, as applicable, to serve as an officer and/or director
on the board of directors of the Company and hereby consents to being named in the Prospectus as an officer and/or director of
the Company.

 

		11.	As used herein, (i) “Business Combination”
shall mean a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or similar business combination,
involving the Company and one or more businesses; (ii) “Common Stock” shall mean the Class A
common stock and Class B common stock; (iii) “Founder Shares” shall mean the 3,250,000 shares

if the over-allotment option is not exercised by the Underwriters); (iv) “Initial Stockholders”
shall mean the Sponsor and any Insider that holds Founder Shares; (v) “Private Placement Shares”
shall mean the up to 460,000 shares (or up to 499,000 shares if the over-allotment option is exercised in full) that the Sponsor
has agreed to purchase for an aggregate purchase price of $4,600,000 (or $4,990,000 if the over-allotment option is exercised
in full), or $10.00 per Share, in a private placement that shall occur simultaneously with the consummation of the Public Offering;
(vi) “Public Stockholders” shall mean the holders of securities issued in the Public Offering;
(vii) “Trust Account” shall mean the trust fund into which a portion of the net proceeds of the
Public Offering and the sale of the Private Placement Shares shall be deposited; and (viii) “Transfer”

or otherwise dispose of or agreement to dispose of, directly or indirectly, or establishment or increase of a put equivalent position
or liquidation with respect to or decrease of a call equivalent position within the meaning of Section 16 of the Exchange
Act, and the rules and regulations of the Commission promulgated thereunder with respect to, any security, (b) entry
into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership

in accordance with its or their terms, to the maximum extent of the coverage available for any of the Company’s directors
or officers.

 

		13.	This Letter Agreement constitutes the entire agreement
and understanding of the parties hereto in respect of the subject matter hereof and supersedes all prior understandings, agreements,
or representations by or among the parties hereto, written or oral, to the extent they relate in any way to the subject matter
hereof or the transactions contemplated hereby. This Letter Agreement may not be changed, amended, modified or waived (other than
to correct a typographical error) as to any particular provision, except by a written instrument executed by all parties hereto.

 

		14.	No party hereto may assign either this Letter Agreement
or any of its rights, interests, or obligations hereunder without the prior written consent of the other parties. Any purported

of New York City or in the State of New York, and irrevocably submit to such jurisdiction and venue, which jurisdiction and venue

RE: Subscription Agreement for Founder Shares

 

Ladies and Gentlemen:

 

We are pleased to accept the
offer Research Alliance Holdings II LLC (the “Subscriber” or “you”) has made to purchase
3,737,500 shares (“Founder Shares”) of the common stock, $0.0001 par value per share (“Common Stock”),
of Research Alliance Corp. II, a Delaware corporation (the “Company”), up to 487,500 of which are subject to
forfeiture by you if the underwriters of the proposed initial public offering (“IPO”) of the Company pursuant
to the registration statement on Form S-1 expected to be filed by the Company in connection with the IPO (the “Registration
Statement”) do not fully exercise their over-allotment option (the “Over-allotment Option”) as described
below. The terms (this “Agreement”) on which the Company is willing to sell the Founder Shares to the Subscriber,
and the Company and the Subscriber’s agreements regarding such Founder Shares, are as follows:

 

1. Purchase
of Founder Shares. For the sum of $25,000.00 (the “Purchase Price”), which the Company acknowledges receiving
in cash, the Company hereby sells and issues the Founder Shares to the Subscriber, and the Subscriber hereby purchases the Founder
Shares from the Company, subject to the forfeiture provisions of Section 3 below, on the terms and subject to the conditions
set forth in this Agreement. 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 Founder Shares, or effect such
delivery in book-entry form.

 

 2. Representations, Warranties and Agreements.

 

2.1. The
Subscriber’s Representations, Warranties and Agreements. To induce the Company to issue the Founder Shares 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 Founder Shares.

 

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,
(iii) any law, statute, rule or regulation to which the Subscriber is subject, or (iv) 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 will be 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 Founder Shares and (ii) able to bear the economic risk of its
investment in the Founder Shares for an indefinite period of time because the Founder Shares have not been registered under
the Securities Act (as defined below) and therefore cannot be resold unless such transaction is 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 Founder Shares are sold pursuant to: (x) an effective registration statement
under the Securities Act or (y) an exemption from registration available with respect to such sale. The Subscriber is
able to bear the economic risks of an investment in the Founder Shares and to afford a complete loss of the
Subscriber’s investment in the Founder Shares.

 

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 or its prospects.

 

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 federal and
state law.

 

2.1.7. Investment
Purposes. The Subscriber is purchasing the Founder Shares 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 enter into this Agreement as a result of any general solicitation or general advertising within the meaning
of Rule 502 of Regulation D under the Securities Act.

 

2.1.8. Restrictions
on Transfer; Shell Company. The Subscriber understands the Founder Shares are being offered in a transaction not involving
a public offering within the meaning of the Securities Act. The Subscriber understands the Founder Shares will be “restricted
securities” as defined in Rule 144(a)(3) under the Securities Act and the Subscriber understands that any certificate
or book entries representing the Founder Shares will contain a legend in respect of such restrictions. If in the future the Subscriber
decides to offer, resell, pledge or otherwise transfer the Founder Shares, such Founder Shares may be offered, resold, pledged
or otherwise transferred only in accordance with the provisions of Section 5 hereof. The Subscriber agrees that if any transfer
of its Founder Shares 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 under the Securities
Act or an exemption therefrom, the Subscriber agrees not to resell the Founder Shares. 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 Founder Shares
until at least one year following consummation of the initial business combination of the Company, despite technical compliance
with the certain 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.

 

     

     

    

 

2.2. Company’s
Representations, Warranties and Agreements. To induce the Subscriber to purchase the Founder Shares, 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 Certificate of
Incorporation or Bylaws of the Company, (ii) any agreement, indenture or instrument to which the Company is a party,
(iii) any law, statute, rule or regulation to which the Company is subject, or (iv) 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, the Founder Shares will be
duly and validly issued, fully paid and nonassessable. Upon issuance in accordance with, and payment pursuant to, the terms
hereof the Subscriber will have or receive good title to the Founder Shares, free and clear of all liens, claims and
encumbrances of any kind, other than (a) transfer restrictions hereunder and other agreements to which the Founder
Shares may be subject which have been notified to the Subscriber in writing, (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 seek to recover damages or to obtain other
relief in connection with any transactions.

 

 3. Forfeiture of Founder 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 (and, if applicable, any transferee of Shares)
shall automatically forfeit at the time such Over-allotment Option expires (or earlier if the underwriters of the IPO waive
their ability to exercise such Over-allotment Option) any and all rights to such number of Founder Shares (up to an aggregate
of 487,500 Founder 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), collectively with all other initial
stockholders of the Company prior to the IPO, will own an aggregate number of Founder Shares equal to 25% of the total number
of shares of Common Stock issued in the IPO.

 

3.2. Termination
of Rights as Stockholder. If any of the Founder Shares are forfeited in accordance with this Section 3, then after such
time the Subscriber (or its successor in interest), shall no longer have any rights as a holder of such forfeited Founder Shares,
and the Company shall take such action as is appropriate to cancel such forfeited Founder Shares.

 

3.3. Share
Certificates. In the event an adjustment to any certificate representing the Founder Shares purchased pursuant hereto is required
pursuant to this Section 3, then the Subscriber shall return such certificate 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
shall be issued in such amount representing the adjusted number of Founder Shares held by the Subscriber. Such 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 Founder 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 securities of the Company issued in the IPO in the
aftermarket, any additional Common Stock so purchased shall be eligible to receive any liquidating distributions from the Trust
Account by the Company. However, in no event will the Subscriber have the right to redeem any shares of Common Stock 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 stock escrow agreement (commonly known as
an “Escrow Agreement”) to be entered into between the Company, the Subscriber and the Company’s transfer
agent in connection with the consummation of the IPO, the Subscriber agrees not to sell, transfer, pledge, hypothecate or otherwise
dispose of all or any part of the Founder Shares unless, prior thereto (a) a registration statement on the appropriate form
under the Securities Act and applicable state securities laws with respect to the Founder Shares 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 Founder Shares will be subject to lock-up provisions (the “Lock-up”) contained
in the Escrow Agreement. Pursuant to the Escrow Agreement, the Subscriber will agree (subject to certain customary exceptions)
not to sell, transfer, pledge, hypothecate or otherwise dispose of all or any part of the Founder Shares until the earlier to occur
of: (A) one year after the completion of the Company’s initial business combination or (B) subsequent to the Company’s
initial business combination, (x) if the last sale price of the Common Stock equals or exceeds $12.00 per share (as adjusted
for stock splits, stock dividends, reorganizations, recapitalizations and the like) for any 20 trading days within any 30-trading
day period commencing at least 150 days after the Company’s initial business combination, or (y) the date on which the
Company completes a liquidation, merger, capital stock exchange, reorganization or other similar transaction that results in all
of the Company’s stockholders having the right to exchange their shares of Common Stock for cash, securities or other property.

 

5.3. Restrictive
Legends. All certificates representing the Founder Shares 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 LOCKUP PROVISIONS AND MAY NOT BE OFFERED, SOLD, TRANSFERRED, PLEDGED OR OTHERWISE DISPOSED
DURING THE TERM OF THE LOCKUP PERIOD.”

 

5.4.
Additional Founder Shares or Substituted Securities. In the event of the declaration of a stock dividend, the declaration
of a special dividend payable in a form other than Common Stock, a spin-off, a stock 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 Founder Shares subject to this Section 5 or into which such Founder Shares 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 or class of Founder Shares subject to this Section 5 and Section 3.

 

5.5. Registration
Rights. The Subscriber acknowledges that the Founder 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 and (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.

 

6.3. Entire
Agreement. This Agreement, together with that certain Escrow Agreement to be entered into between the Subscriber and the Company
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. No statement, representation,
warranty, covenant or agreement of any kind not expressly set forth in this Agreement shall affect, or be used to interpret, change
or restrict, the express terms and provisions of this Agreement.

 

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 Delaware applicable to contracts wholly performed within the borders of such state.

 

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.

 

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 hold 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 sections 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 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 section
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.

 

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 Redemption of Founder Shares. The Subscriber agrees to vote the Founder Shares in favor of an initial business
combination that the Company negotiates and submits for approval to the Company’s stockholders.

 

8.
Indemnification. Each party shall indemnify the other against any loss, cost or damages (including reasonable attorneys’
fees and expenses) incurred as a result of such party’s breach of any representation, warranty, covenant or agreement in
this Agreement.
