Re: Alpha Star Acquisition Corporation Public Offering;
Voting, Lock-Up and Waiver


 


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 Alpha Star Acquisition Corporation, a Cayman Islands
exempted company (the “Company”), and Ladenburg Thalmann & Co. Inc., 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 11,500,000 of the Company’s
units (including up to 1,150,000 units that may be purchased to cover over-allotments, if any) (the “Units”),
each comprised of one of the Company’s ordinary shares, par value $0.001 per share (the “Ordinary Shares”),
one warrant to purchase one-half of an Ordinary Share (“Warrant”) and a right (“Right”) to receive
1/10th of an Ordinary Share. Each Warrant entitles the holder thereof to purchase one-half
of one 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 (File No. 333-257521) 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 and components thereof listed on the Nasdaq Capital Market. Certain capitalized terms used herein are defined in Section 12
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, A-Star Management Corp. (the “Sponsor”)
and the undersigned individuals, each of whom is a member of the Company’s board of directors and/or management team (each, an “Insider”
and collectively, the “Insiders”), hereby agrees with the Company as follows:


 


1. The Sponsor and each Insider
agrees that (A) 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, (B) if the Company engages
in a tender offer in connection with any proposed Business Combination, it, he or she shall not sell any Shares to the Company in connection
therewith and (C) if the Company seeks shareholder approval of any proposed amendment to the Charter prior to the consummation of
a Business Combination, it, he or she shall 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 time period set forth
in 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 10 business days thereafter,
subject to lawfully available funds therefor, redeem 100% of the 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 earned on the funds held in the Trust Account and not previously released to the
Company to pay any taxes (less up to $50,000 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 the case of clauses (ii) and (iii) above 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 Charter (i) that would affect 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
time period described in the Prospectus or (ii) with respect to any other provision relating to shareholders’ rights or
pre-Business Combination activity, unless the Company provides its public shareholders with the opportunity to redeem their Ordinary
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 any taxes, divided by the number of then outstanding Offering Shares.


 


3. 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 any claim such Sponsor or Insider may have in the future as a result of, or arising out
of, any contracts or agreements with the Company and will not seek recourse against the Trust Account for any reason whatsoever except
in each case with respect to the Insider’s right to a pro rata interest in the proceeds held in the Trust Account for any Offering
Shares such Sponsor or Insider may hold.


 


4. 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,
and the rules and regulations of the Commission promulgated thereunder, with respect to any Units, Ordinary Shares, Founder Shares,
Warrants, Rights or any securities convertible into, or exercisable, or exchangeable for, Ordinary Shares 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
Units, Ordinary Shares, Founder Shares, Warrants, Rights or any securities convertible into, or exercisable, or exchangeable for, Ordinary
Shares 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). 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 Section 4
or Section 8 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 Section 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.


 


5. In the event of the
liquidation of the Trust Account, the Sponsor (which for purposes of clarification shall not extend to any other shareholders,
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 for services rendered or products sold to the
Company or (ii) a prospective target business with which the Company has entered into a letter of intent, confidentiality or
other similar agreement or a Business Combination 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 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.


 






     

     


    

 


6. To
the extent that the Underwriters do not exercise their over-allotment option to purchase up to an additional 1,150,000 Units 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
1,150,000 minus the number of Units purchased by the Underwriters upon the exercise of their over-allotment option, and
(ii) the denominator of which is 1,150,000.




 


7. 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 Sections 1, 2, 3, 4, 5, 8(a), 8(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.


 


8. (a) The Sponsor and
each Insider agrees that it, he or she shall not (a) Transfer 50% of their Founder Shares until the earlier of (A) six months
after the consummation of the Company’s initial Business Combination or (B) the date on which the closing price of the Ordinary
Shares equals or exceeds $12.50 per share (as adjusted for share splits, share capitalizations, rights issuances, subdivisions, reorganizations,
recapitalizations and the like) for any 20 trading days within any 30-trading day period commencing after the Company’s initial
Business Combination or (b) Transfer the remaining 50% of their Founder Shares until six months after the date of the consummation
of the Company’s initial Business Combination, or earlier in either case, if subsequent to the Company’s initial Business
Combination the Company completes a liquidation, merger, share exchange, reorganization or other similar transaction that results in all
of the Company’s 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 (or Warrants and Ordinary Shares issued or issuable
upon the conversion of the Private Placement Units), until 30 days after the completion of a Business Combination (the “Private
Placement Units Lock-up Period”, together with the Founder Shares Lock-up Period, the “Lock-up Periods”).


 


(c) Notwithstanding
the provisions set forth in Sections 8(a) and (b), Transfers of the Founder Shares, Private Placement Units and Warrants and
Ordinary Shares issued or issuable upon the exercise or conversion of the Private Placement Units and that are held by the Sponsor,
any Insider or any of their permitted transferees (that have complied with this Section 8(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, any
members of the Sponsor, or any affiliates of the Sponsor; (b) in the case of an individual, transfers by gift to a member of
the individual’s immediate family, 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, transfers by virtue of laws
of descent and distribution upon death of the individual; (d) in the case of an individual, transfers pursuant to a qualified
domestic relations order; (e) transfers by private sales or transfers made in connection with the consummation of a Business
Combination at prices no greater than the price at which the securities were originally purchased; (f) transfers in the event
of the Company’s liquidation prior to the completion of an initial Business Combination; (g) transfers by virtue of the
laws of the Cayman Islands or the Sponsor’s limited liability company agreement upon dissolution of the Sponsor; (h) in
the event of the Company’s liquidation, merger, share exchange, reorganization or other similar transaction which results in
all of the Company’s shareholders having the right to exchange their Ordinary Shares for cash, securities or other property
subsequent to the completion of the Company’s initial Business Combination; and (i) transfers in connection with the
Company’s initial Business Combination with the Company’s consent to any third party; provided, however, that in the
case of clauses (a) through (e), (h) and (i), these permitted transferees must enter into a written agreement agreeing to
be bound by the restrictions herein.

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
