Re: Initial Public
Offering

 

Ladies and Gentlemen:

 

This letter is being delivered
to you in accordance with the Underwriting Agreement (the “Underwriting Agreement”) entered into by and between
Gardiner Healthcare Acquisitions Corp., a Delaware corporation (the “Company”) and Chardan Capital Markets,
LLC, as representative (the “Representative”) of the Underwriters named in Schedule A thereto (the “Underwriters”),
relating to an underwritten initial public offering (the “IPO”) of the Company’s units (the “Units”),
each comprised of one share of Common Stock of the Company, par value $0.0001 per share (the “Common Stock”)
and one warrant, with each warrant being exercisable to purchase one share of Common Stock at a price of $11.50 per full share (“Warrant”).
Certain capitalized terms used herein are defined in paragraph 15 hereof.

 

In order to induce the Company
and the Underwriters to enter into the Underwriting Agreement and to proceed with the IPO, and in recognition of the benefit that such
IPO will confer upon each of the undersigned as a stockholder of the Company, and for other good and valuable consideration, the receipt
and sufficiency of which are hereby acknowledged, each of the undersigned hereby agrees with the Company as follows:

 

1.                 
If the Company solicits approval of its stockholders of a Business Combination, each of the undersigned will vote all shares
of Common Stock beneficially owned by it, whether acquired before, in or after the IPO, in favor of such Business Combination.

 

    1

     

    

 

2.                  To
the extent that the Underwriters do not exercise their over-allotment option to purchase up to an additional 1,125,000 Units (as
described in the Registration Statement), (a) Gardiner Healthcare Holdings, LLC (“Gardiner Healthcare”)
agrees that it shall forfeit, at no cost, a number of Founder Shares in the aggregate equal to 182,812 multiplied by a fraction, (i)
the numerator of which is 1,125,000 minus the number of Units purchased by the Underwriters upon the exercise of their
over-allotment option and (ii) the denominator of which is 1,125,000, (b) Chardan Gardiner LLC agrees that it shall forfeit, at no
cost, a number of Founder Shares in the aggregate equal to 50,625 multiplied by a fraction, (i) the numerator of which is 1,125,000
minus the number of Units purchased by the Underwriters upon the exercise of their over-allotment option and (ii) the denominator of
which is 1,125 ,000 and (c) CCMAUS Pty Ltd agrees that it shall forfeit, at no cost, a number of Founder Shares in the aggregate
equal to 47,813 multiplied by a fraction, (i) the numerator of which is 1,125,000 minus the number of Units purchased by the
Underwriters upon the exercise of their over-allotment option and (ii) the denominator of which is 1,125,000. All references in this
letter to Founder Shares of the Company being forfeited shall take effect as a contribution of such Founder Shares to the
Company’s capital as a matter of Delaware 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 number of Founder Shares will equal an aggregate of 20.0% of the
Company’s issued and outstanding IPO Shares and Founder Shares after the IPO. The undersigned further agrees that to the
extent that the size of the IPO is increased or decreased, the Company will effect a capitalization or stock repurchase or
redemption, as applicable, immediately prior to the consummation of the IPO in such amount as to maintain the number of Founder
Shares at 20.0% of the Company’s issued and outstanding IPO Shares and Founder Shares upon the consummation of the IPO. In
connection with such increase or decrease in the size of the IPO, then (A) the references to 1,125,000 in the numerator and
denominator of the formula in the first sentence of this paragraph shall be changed to a number equal to 15.0% of the number of
shares of Common Stock included in the Units issued in the IPO, (B) the reference to 182,812, 50,625 and 47,813 in the formula set
forth in the first sentence of this paragraph shall be adjusted to, respectively, (i) the total number of Founder Shares that
Gardiner Healthcare would have to return to the Company in order for the number of Founder Shares that Gardiner Healthcare owns
(together with the Insiders) to equal an aggregate of 12.3% of the Company’s issued and outstanding IPO Shares and Founder
Shares after the IPO, (ii) the total number of Founder Shares that Chardan Gardiner LLC would have to return to the Company in order
for the number of Founder Shares that Chardan Gardiner LLC owns (together with Insiders) to equal an aggregate of 3.4% of the
Company’s issued and outstanding IPO Shares and Founder Shares after the IPO, and (iii) the total number of Founder Shares
that CCMAUS Pty Ltd would have to return to the Company in order for the number of Founder Shares that CCMAUS Pty Ltd owns (together
with Insiders) to equal an aggregate of 3.2% of the Company’s issued and outstanding IPO Shares and Founder Shares after the
IPO.

 

3.                 
The undersigned agrees that the Founder Shares and Private Warrants held by it, and any shares of Common Stock issued upon
conversion or exercise thereof, shall not be sold during the IPO, or sold, transferred, assigned, pledged, or hypothecated, or be the
subject of any hedging, short sale, derivative, put, or call transaction that would result in the effective economic disposition of such
securities by any person for a period of 180 days immediately following the date of effectiveness of the Registration Statement or commencement
of sales of the IPO, except to any underwriter and selected dealer participating in the IPO and their bona fide officers or partners;
provided that all securities so transferred remain subject to the foregoing lockup restriction for the remainder of the time period.

 

4.                 
 

 

(a)               In
the event that the Company fails to consummate a Business Combination within 12 months (or in the event the Company extends the time
to complete a Business Combination as described in the Registration Statement, 15 or 18 months) from the closing of the
Company’s IPO, or such later period approved by the Company’s stockholders in accordance with the Company’s
amended and restated certificate of incorporation, the undersigned shall take all reasonable steps to (i) cause the Trust Fund to be
liquidated and distributed to the holders of IPO Shares and (ii) cause the Company to liquidate as promptly as reasonably possible
but not more than five business days after the date the Company is required to consummate a Business Combination.

 

    2

     

    

 

(b)              
The undersigned hereby waives any and all right, title, interest or claim of any kind in or to any distribution of the Trust
Fund and any remaining net assets of the Company as a result of such liquidation with respect to any shares it owns, including its Insider
Shares, IPO Shares and Private Warrants, purchased during or after the offering, if any (“Claim”), and hereby
waives any Claim the undersigned 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 Fund for any reason whatsoever. Each of the undersigned acknowledges and agrees that there
will be no distribution from the Trust Fund with respect to any Common Stock underlying the Private Warrants, all rights of which will
terminate on the Company’s liquidation.

 

(c)              
In the event of the liquidation of the Trust Fund, Gardiner Healthcare agrees to indemnify and hold harmless the Company
against any and all loss, liability, claims, 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) which the Company may become subject as a result of any claim by any vendor or other person who is owed money by the Company
for services rendered or products sold or contracted for, but only to the extent necessary to ensure that such loss, liability, claim,
damage or expense does not reduce the amount of funds in the Trust Fund; provided, that such indemnity shall not apply if such
vendor or other person has executed an agreement waiving any claims against the Trust Fund.

 

(d)              
In the event that the Company does not consummate a Business Combination and must liquidate and its remaining net assets
are insufficient to complete such liquidation, Gardiner Healthcare agrees to advance such funds necessary to complete such liquidation
and agrees not to seek repayment for such expenses.

 

5.                  Each
of the undersigned will place into escrow all of its Insider Shares pursuant to the terms of a Stock Escrow Agreement which the
Company will enter into with the undersigned and an escrow agent acceptable to the Company. Each of the undersigned agrees that
during the escrow period, the undersigned shall not sell or transfer its Insider Shares except (1) to any persons (including their
affiliates and stockholders) participating in the private placement of the Private Warrants, officers, directors, stockholders,
employees and members of Gardiner Healthcare, Chardan Gardiner LLC, and CCMAUS Pty Ltd and their affiliates, (2) amongst initial
stockholders or to the Company’s officers, directors and employees, (3) if a holder is an entity, as a distribution to its,
partners, stockholders or members upon its liquidation, (4) by bona fide gift to a member of the holder’s immediate family or
to a trust, the beneficiary of which is a holder or a member of a holder’s immediate family, for estate planning purposes, (5)
by virtue of the laws of descent and distribution upon death, (6) pursuant to a qualified domestic relations order, (7) by certain
pledges to secure obligations incurred in connection with purchases of the Company’s securities, (8) by private sales at
prices no greater than the price at which the shares were originally purchased or (9) for the cancellation of up to 281,250 shares
of Common Stock subject to forfeiture to the extent that the Underwriters’ over-allotment option is not exercised in full or
in part or in connection with the consummation of the Company’s initial Business Combination, in each case (except for clause
9 or with the prior consent of the Representative) where the transferee agrees to the terms of the escrow agreement and this insider
letter.

 

    3

     

    

 

6.                 
Each of the undersigned agrees that until the Company consummates a Business Combination, its Private Warrants will be subject
to the transfer restrictions described in the Private Placement Warrants Purchase Agreement relating to its Private Warrants.

 

7.                 
[RESERVED]

 

8.                 
The undersigned acknowledges and agrees that prior to entering into a Business Combination with a target business that is
affiliated with any Insiders of the Company or their affiliates, including any company that is a portfolio company of, or otherwise affiliated
with, or has received financial investment from, an entity with which any Insider or their affiliates is affiliated, such transaction
must be approved by a majority of the Company’s disinterested independent directors and the Company must obtain an opinion from
an independent investment banking firm that such Business Combination is fair to the Company’s unaffiliated stockholders from a
financial point of view.

 

9.                 
Neither Gardiner Healthcare nor any affiliate of Gardiner Healthcare will be entitled to receive or accept a finder’s
fee or any other compensation in the event Gardiner Healthcare or any affiliate of Gardiner Healthcare originates a Business Combination.

Re: Initial Public Offering

 

Ladies and Gentlemen:

 

This letter is being delivered
to you in accordance with the Underwriting Agreement (the “Underwriting Agreement”) entered into by and between
Gardiner Healthcare Acquisitions Corp., a Delaware corporation (the “Company”) and Chardan Capital Markets,
LLC, as representative (the “Representative”) of the Underwriters named in Schedule A thereto (the “Underwriters”),
relating to an underwritten initial public offering (the “IPO”) of the Company’s units (the “Units”),
each comprised of one share of Common Stock of the Company, par value $0.0001 per share (the “Common Stock”)
and one warrant, with each warrant being exercisable to purchase one share of Common Stock at a price of $11.50 per full share (“Warrant”).
Certain capitalized terms used herein are defined in paragraph 12 hereof.

 

In order to induce the Company
and the Underwriters to enter into the Underwriting Agreement and to proceed with the IPO, and in recognition of the benefit that such
IPO will confer upon the undersigned as a stockholder of the Company, and for other good and valuable consideration, the receipt and sufficiency
of which are hereby acknowledged, the undersigned hereby agrees with the Company as follows:

 

1.            If
the Company solicits approval of its stockholders of a Business Combination, the undersigned will vote all shares of Common Stock beneficially
owned by him, whether acquired before, in or after the IPO, in favor of such Business Combination.

 

2.

 

(a)              
In the event that the Company fails to consummate a Business Combination within 12 months (or in the event the Company
extends the time to complete a Business Combination as described in the Registration Statement, 15 or 18 months) from the closing of
the Company’s IPO or such later period approved by the Company’s stockholders in accordance with the Company’s amended
and restated certificate of incorporation, the undersigned shall take all reasonable steps to (i) cause the Trust Fund to be liquidated
and distributed to the holders of IPO Shares and (ii) cause the Company to liquidate as promptly as reasonably possible but not more
than five business days after the date we are required to consummate a Business Combination.

 

     

     

    

 

(b)            The
undersigned hereby waives any and all right, title, interest or claim of any kind in or to any distribution of the Trust Fund and any
remaining net assets of the Company as a result of such liquidation with respect to any shares he owns, including his Insider Shares, IPO
Shares and Private Warrants purchased during or after the offering, if any, (“Claim”) and hereby waives any
Claim the undersigned 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 Fund for any reason whatsoever.

 

3.            The
undersigned will place into escrow all of his Insider Shares pursuant to the terms of a Stock Escrow Agreement which the Company will
enter into with the undersigned and an escrow agent acceptable to the Company. The undersigned agrees that during the escrow period (as
described in the Registration Statement), the undersigned shall not sell or transfer its Insider Shares except (1) to any persons
(including their affiliates and stockholders) participating in the private placement of the Private Warrants, officers, directors, stockholders,
employees and members of the co-sponsors and their affiliates, (2) amongst initial stockholders or to the Company’s officers,
directors and employees, (3) if a holder is an entity, as a distribution to its, partners, stockholders or members upon its liquidation,

4.            In
order to minimize potential conflicts of interest which may arise from multiple affiliations, the undersigned agrees to present to the
Company for its consideration, prior to presentation to any other person or entity, any suitable opportunity to acquire a target business,
until the earlier of the consummation by the Company of a Business Combination or the liquidation of the Company, subject to any pre-existing
fiduciary and contractual obligations the undersigned might have.

 

5.            The
undersigned acknowledges and agrees that prior to entering into a Business Combination with a target business that is affiliated with
any Insiders of the Company or their affiliates, including any company that is a portfolio company of, or otherwise affiliated with, or
has received financial investment from, an entity with which any Insider or their affiliates is affiliated, such transaction must be approved
by a majority of the Company’s disinterested independent directors and the Company must obtain an opinion from an independent investment
banking firm that such Business Combination is fair to the Company’s unaffiliated stockholders from a financial point of view.

 

6.            Neither
the undersigned, any member of the family of the undersigned, nor any affiliate of the undersigned will be entitled to receive or accept
