Acquisition Corp. 
 345 Park Avenue South, 12th Floor 

New York, NY 10010 
 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 DA32 Life Science Tech Acquisition Corp., a Delaware corporation (the
“Company”), and J.P. Morgan Securities LLC and Cowen and Company, LLC, as representatives of the several underwriters (each, an “Underwriter” and collectively, the
“Underwriters”), relating to an underwritten initial public offering (the “Public Offering”), of up to 23,000,000 shares of the Company’s Class A common stock, par value $0.0001
per share (including up to 3,000,000 shares that may be purchased to cover over-allotments, if any) (the “Class A Common Stock”). The Class A Common Stock 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 Class A Common Stock 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 DA32 Sponsor LLC, a Delaware limited liability company (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 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 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 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.	 Notwithstanding the provisions set forth in paragraphs in 7(a) and 7(b), 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 Underwriters, (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 shares of Common Stock (including, but not limited to,
Founder Shares) or any securities convertible into, or exercisable, or exchangeable for, shares of Class A 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 shares of Common Stock (including, but not limited to, Founder Shares) or any securities convertible into, or exercisable, or exchangeable for, shares of Class A 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, all of 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 may 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. 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.


  

	 	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 (other than the independent registered public accounting firm) 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 for services rendered (other than the independent registered public accounting firm) or products sold to the Company 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
3,000,000 shares of Class A Common Stock 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 750,000
multiplied by a fraction, (i) the numerator of which is 3,000,000 minus the number of Class A Common Stock purchased by the Underwriters upon the exercise of their over-allotment option, and (ii) the denominator of which is 3,000,000.
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 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 Class A Common Stock or effect a stock dividend or share contribution back to capital, as applicable, immediately prior to the consummation of the Public Offering in such amount as to maintain the number of Founder Shares at
20.0% of its issued and outstanding shares of Class A Common Stock upon the consummation of the Public Offering. In connection with such increase or decrease in the size of the Public Offering, (A) the references to 3,000,000 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 shares of Class A Common Stock issued in the Public Offering and (B) the reference to 750,000 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 number of Founder Shares to equal 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), 7(b) and 9, 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 (as
defined below) 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 capitalizations, 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 and shares of Class A Common Stock issued or issuable upon the conversion of 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 affiliate or family member of any of the Company’s officers or directors, any affiliate of the Sponsor or to any members of the Sponsor or any of their affiliates; (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) in the event of the Company’s liquidation prior to the completion of an initial
Business Combination; (g) by virtue of the laws of the State of Delaware or the Sponsor’s limited liability company agreement upon dissolution of the Sponsor; or (h) 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 (e) or (g), 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 such 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 $200,000 made to the Company by the Sponsor to cover offering-related
and organizational expenses; payments to the Sponsor for certain office space, secretarial and administrative services as may be reasonably required by the Company of $10,000 per month; reimbursement for any reasonable
out-of-pocket expenses related to identifying, investigating, negotiating and consummating 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 of Class A Common Stock at a price of $10.00 per share at the
option of the lender. Such shares of Class A Common Stock 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
of the Company, par value $0.0001 per share (the “Class B Common Stock”); (iii) “Founder Shares” shall mean the 5,750,000 shares of Class B Common Stock issued and
outstanding immediately prior to the consummation of the Public Offering (up to 750,000 shares of which are subject to forfeiture by the Sponsor 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 650,000 shares of Class A Common Stock (or 710,000 shares if the over-allotment
option is exercised in full) that the Sponsor has agreed to purchase for an aggregate purchase price of $6,500,000 (or $7,100,000 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” shall mean the (a) sale of, offer to sell, contract or agreement
to sell, hypothecate, pledge, grant of any option to purchase 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 of any security, whether any such transaction is to be settled by delivery of such securities, in cash or otherwise, or (c) public announcement of any intention to
effect any transaction specified in clause (a) or (b). 


  

	 	12.	 The Company will maintain an insurance policy or policies providing directors’ and officers’
liability insurance, and each of the Company’s directors and officers shall be covered by such policy or policies, 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 assignment in violation of this paragraph shall be void and ineffectual and shall not operate to transfer or assign any interest or title to the purported assignee. This
Letter Agreement shall be binding on the Sponsor and each Insider and their respective successors, heirs and assigns and permitted transferees. 


  

	 	15.	 Nothing in this Letter Agreement shall be construed to confer upon, or give to, any person or corporation other
than the parties hereto any right, remedy or claim under or by reason of this Letter Agreement or of any covenant, condition, stipulation, promise or agreement hereof. All covenants, conditions, stipulations, promises and agreements contained in
this Letter Agreement shall be for the sole and exclusive benefit of the parties hereto and their successors, heirs, personal representatives and assigns and permitted transferees. 



 

	 	16.	 This Letter Agreement may be executed in any number of original or facsimile counterparts and each of such
counterparts shall for all purposes be deemed to be an original, and all such counterparts shall together constitute but one and the same instrument. The words “executed,” “signed,” “signature,” and words of like import
in this Letter Agreement or in any other certificate, agreement or document related to this Letter 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 record-keeping system to the
fullest extent permitted by applicable law, including the Federal 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 or the Uniform Commercial Code. 


  

	 	17.	 This Letter Agreement shall be deemed severable, and the invalidity or unenforceability of any term or
provision hereof shall not affect the validity or enforceability of this Letter Agreement or of any other term or provision hereof. Furthermore, in lieu of any such invalid or unenforceable term or provision, the parties hereto intend that there
shall be added as a part of this Letter Agreement a provision as similar in terms to such invalid or unenforceable provision as may be possible and be valid and enforceable. 



 

	 	18.	 This Letter Agreement shall be governed by and construed and enforced in accordance with the laws of the State
of New York, without giving effect to conflicts of law principles that would result in the application of the substantive laws of another jurisdiction. The parties hereto (i) all agree that any action, proceeding, claim or dispute arising out
of, or relating in any way to, this Letter Agreement shall be brought and enforced in the courts of New York City, in the State of New York, and irrevocably submit to such jurisdiction and venue, which jurisdiction and venue shall be exclusive and
(ii) waive any objection to such exclusive jurisdiction and venue or that such courts represent an inconvenient forum. 















	 	19.	 Any notice, consent or request to be given in connection with any of the terms or provisions of this Letter
Agreement shall be in writing and shall be sent by express mail or similar private courier service, by certified mail (return receipt requested), by hand delivery or facsimile transmission. 



 

	 	20.	 This Letter Agreement shall terminate on the earlier of (i) the expiration of the Lock-up Periods and (ii) the liquidation of the Company; provided, however, that this Letter Agreement shall earlier terminate in the event that the Public Offering is not consummated and closed by
December 31, 2021; provided further that paragraph 4 of this Letter Agreement shall survive such liquidation.
