	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”)
to be entered into by and between Translational Development Acquisition Corp., a Cayman Islands exempted company (the “Company”),
and ThinkEquity LLC (the “Representative”), as the representative of the several underwriters (the “Underwriters”),
relating to an underwritten initial public offering (the “Public Offering”) of 17,250,000 of the Company’s
units (including up to 2,250,000 units that may be purchased to cover over-allotments, if any) (the “Units”),
each comprised of one Class A ordinary share of the Company, par value $0.0001 per share (the “Class A ordinary
shares”), and one-half of one warrant (each, a “Warrant”). Each whole Warrant entitles the holder
thereof to purchase one Class A ordinary share at a price of $11.50 per share, subject to adjustment. The Units shall 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 Securities and Exchange Commission (the “Commission”) and the Company shall apply
to have the Units listed on the Nasdaq Global Market. Certain capitalized terms used herein are defined in paragraph 10 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, Stone Capital Partners LLC (the “Sponsor”),
and the other undersigned persons (each, 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 shareholder approval of a proposed Business Combination, then in connection with such proposed Business
Combination, it, he or she shall (i) vote any Shares owned by it, him or her in favor of any proposed Business Combination and (ii) not
redeem any Shares owned by it, him or her in connection with such shareholder approval.

 

2. The Sponsor and each Insider
hereby agrees that in the event that the Company fails to consummate a Business Combination within the completion window (as defined in
the Prospectus), or such later period approved by the Company’s shareholders in accordance with the Company’s amended and
restated memorandum and articles of association, 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
(10) business days thereafter, subject to lawfully available funds therefor, redeem 100% of the Class A ordinary shares sold
as part of the Units 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, including interest (which interest shall be net of taxes payable and
less 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 Shareholders’ rights as shareholders (including the right to receive further liquidation distributions,
if any), subject to applicable law, and (iii) as promptly as reasonably possible following such redemption, subject to the approval
of the Company’s remaining shareholders and the Company’s board of directors, dissolve and liquidate, subject in each case
to the Company’s obligations under Cayman Islands 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 Company’s amended and restated memorandum and articles of
association (a) that would affect the ability of Public Shareholders to exercise redemption rights with respect to the Offering Shares
or 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 completion window (as defined in the Prospectus) or (b) with respect to any other provision relating
to shareholders’ rights or pre-initial Business Combination activity, unless the Company provides its Public Shareholders 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 (which interest shall be net of taxes payable), 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 (including any Class A
ordinary shares issuable upon conversion thereof) and the Private Placement Shares held by such Sponsor or Insider. The Sponsor and each
Insider hereby further waives, with respect to the Founder Shares (including any Class ordinary shares issuable upon conversion thereof)
and the Private Placement Shares held by it, him or her, if any, any redemption rights it, he or she may have in connection with the consummation
of a Business Combination, including, without limitation, any such rights available in the context of a shareholder vote to approve such
Business Combination or in the context of a tender offer made by the Company to purchase Class A ordinary shares (although the Sponsor
and the Insiders 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 completion window (as defined in the Prospectus) or such later period approved by
the Company’s shareholders in accordance with the Company’s amended and restated memorandum and articles of association).

 

3. In the event of the liquidation
of the Trust Account, the Sponsor (which for purposes of clarification shall not extend to any other equityholders, members or managers
of the Sponsor) 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, or any claim whatsoever) to which the Company may become subject as a result of any claim
by (i) any third party (other than the Company’s independent public accountants) for services rendered or products sold to
the Company or (ii) a prospective target business with which the Company has discussed entering into a transaction agreement (a “Target”);
provided, however, that such indemnification of the Company by the Sponsor shall apply only to the extent necessary to ensure
that such claims by a third party for services rendered (other than the Company’s independent public accountants) or products sold
to the Company or a Target do not reduce the amount of funds in the Trust Account to below (i) $10.00 per share of the Offering Shares
or (ii) such lesser amount per share of the Offering Shares held in the Trust Account due to reductions in the value of the trust
assets as of the date of the liquidation of the Trust Account, in each case, net of the amount of interest earned on the property in the
Trust Account which may be withdrawn to pay taxes, except as to any claims by a third party (including a Target) who executed a waiver
of any and all rights to seek access to the Trust Account and except as to any claims under the Company’s indemnity of the Underwriters
against certain liabilities, including liabilities under the Securities Act of 1933, as amended. In the event that any such executed waiver
is deemed to be unenforceable against such third party, the Sponsor shall not be responsible to the extent of any liability for such third
party claims. The Sponsor 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 Sponsor, the Sponsor notifies the Company in writing
that it shall undertake such defense.

 

4. To the extent that the
Underwriters do not exercise their over-allotment option to purchase up to an additional 2,250,000 Units within 45 days from the date
of the Prospectus (and as further described in the Prospectus), the Sponsor agrees that it shall forfeit, at no cost, a number of Founder
Shares in the aggregate equal to 562,500 multiplied by a fraction, (i) the numerator of which is 2,250,000 minus the number of Units
purchased by the Underwriters upon the exercise of their over-allotment option, and (ii) the denominator of which is 2,250,000.

 

All references in this Letter
Agreement to Founder Shares of the Company being forfeited shall take effect as surrenders for no consideration of such Founder Shares
as a matter of Cayman Islands law. 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 20.0% of the Company’s issued and outstanding Shares after the Public
Offering (assuming the Initial Shareholders do not purchase any units in the Public Offering and excluding the Representatives Shares).
The Initial Shareholders further agree that to the extent that the size of the Public Offering is increased or decreased, the Company
will effect a capitalization or share repurchase or redemption or other appropriate mechanism, 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 the Company’s issued and outstanding Shares upon the consummation of the Public Offering (assuming the Initial Shareholders
do not purchase any units in the Public Offering and excluding the Representatives Shares). In connection with such increase or decrease
in the size of the Public Offering, then (A) the references to 2,250,000 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 Class A ordinary shares included in the Units
issued in the Public Offering and (B) the reference to 562,500 in the formula set forth in the immediately preceding sentence shall
be adjusted to such number of Founder Shares that the Founder Shares would represent an aggregate of 20.0% of the Company’s issued
and outstanding Shares after the Public Offering (assuming the Initial Shareholders do not purchase any units in the Public Offering and
excluding the Representatives Shares).

 

    2 

     

    

 

5. 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 Insider of its, his or her obligations under paragraphs 1, 2, 3, 4, 6(a), 6(b) and 8 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 seek injunctive relief,
in addition to any other remedy that such party may have in law or in equity, in the event of such breach.

 

6. (a) Subject to customary,
minor exceptions, the Sponsor and each Insider, shall not to transfer, assign or sell any Founders Shares, and to maintain their Founders
Shares in escrow, until twelve months after the date of the consummation of the Company’s initial Business Combination (all founder
shares will also be released from escrow and lock-up, if sooner than the above, on the date on which the Company consummates a liquidation,
merger, amalgamation, share exchange, reorganization or other similar transaction after its initial Business Combination that results
in all of its shareholders having the right to exchange their ordinary shares 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 Units, including the Private Placement Shares and the Private
Placement Warrants (or Class A ordinary shares issued or issuable upon the conversion or exercise of the Private Placement Warrants),
until 30 days after the completion of a Business Combination (the “Private Placement Securities Lock-up Period”,
together with the Founder Shares Lock-up Period, the “Lock-up Periods”).

 

(c) Notwithstanding the
provisions set forth in paragraphs 6(a) and 6(b), Transfers of the Founder Shares, Private Placement Units, Private Placement Warrants
and Class A ordinary shares issued or issuable upon the exercise or conversion of the Private Placement Warrants or the Founder Shares
by the Sponsor and the Insiders during the Lock-up Periods are permitted (a) to the Company’s officers or directors, any affiliates
or family members of any of the Company’s officers or directors, any members of the Sponsor or any affiliates of the Sponsor; (b) in
the case of an individual, by gift to a member of the individual’s immediate family, or to a trust, the beneficiary of which is
a member of the individual’s immediate family or an affiliate of such person, or to a charitable organization; (c) in the case
of an individual, by virtue of laws of descent and distribution upon death of the 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 the consummation of the Company’s
Business Combination at prices no greater than the price at which the securities were originally purchased; (f) in the event of the
Company’s liquidation prior to the Company’s completion of an initial Business Combination; (g) by virtue of the laws
of the Cayman Islands or the Sponsor’s limited partnership agreement, as amended from time to time, upon dissolution of the Sponsor;
or (h) in the event of the Company’s completion of a liquidation, merger, amalgamation, share exchange, reorganization or other
similar transaction which results in all of the Company’s shareholders having the right to exchange their Class A ordinary
shares for cash, securities or other property subsequent to the completion of the Company’s initial Business Combination; provided,
however, that, except in the case of clause (a) through (e) or (g) these permitted transferees (the “Permitted
Transferees”) must enter into a written agreement with the Company agreeing to be bound by the transfer restrictions in
this Agreement and by the same agreements entered into by our sponsor with respect to such securities (including provisions relating to
voting, the trust account and liquidation distributions described elsewhere in this prospectus).

 

7. 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, if any (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 such Insider’s background. The Sponsor and each Insider’s
questionnaire furnished to the Company, if any, is true and accurate in all respects. The Sponsor and each Insider represents and warrants

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.

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).

 

9. 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
