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 487,500 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 487,500 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.
