Cactus Acquisition Corp

Management L.P., a Delaware limited partnership, or its registered assigns or successors in interest (the “Payee”),
the principal sum of THREE HUNDRED THOUSAND DOLLARS ($300,000) or such lesser amount as shall have been advanced by Payee to Maker and
that shall remain unpaid under this Note on the Maturity Date (as defined below) in lawful money of the United States of America, on the
terms and conditions described below.  All payments on this Note shall be made by check or wire transfer of immediately available

The entire unpaid principal balance of Note shall be payable on the earlier of:  (i) September 30, 2021, or (ii) the date
on which Maker consummates an initial public offering of its securities (such earlier date, the “Maturity Date”). 
The principal balance may be prepaid at any time. Under no circumstances shall any individual, including but not limited to any officer,

of its securities (the “IPO”).  Principal of this Note may be drawn down from time to time prior to the Maturity
Date upon written request from Maker to Payee (each, a “Drawdown Request”).  Each Drawdown Request must state
the amount to be drawn down, and must not be an amount less than Five Thousand Dollars ($5,000).  Payee shall fund each Drawdown
Request no later than three (3) business days after receipt of a Drawdown Request; provided, however, that the maximum
amount of drawdowns outstanding under this Note at any time may not exceed Three Hundred Thousand Dollars ($300,000).  No fees, payments
or other amounts shall be due to Payee in connection with, or as a result of, any Drawdown Request by Maker.

 

3. Interest. 
No interest shall accrue on the unpaid principal balance of this Note.

 

4. Application
of Payments.  All payments shall be applied first to payment in full of any costs incurred in the collection of any
sum due under this Note, including (without limitation) reasonable attorney’s fees, then to the payment in full of any late charges
and finally to the reduction of the unpaid principal balance of this Note.

 

5. Events

trustee, custodian, sequestrator (or other similar official) of Maker or for any substantial part of its property, or the making by it
of any assignment for the benefit of creditors, or the failure of Maker generally to pay its debts as such debts become due, or the taking
of corporate action by Maker in furtherance of any of the foregoing.

waived, anything contained herein or in the documents evidencing the same to the contrary notwithstanding.

and notice of protest with regard to the Note, all errors, defects and imperfections in any proceedings instituted by Payee under the
terms of this Note, and all benefits that might accrue to Maker by virtue of any present or future laws exempting any property, real or
personal, or any part of the proceeds arising from any sale of any such property, from attachment, levy or sale under execution, or providing
for any stay of execution, exemption from civil process, or extension of time for payment; and Maker agrees that any real estate that
may be levied upon pursuant to a judgment obtained by virtue hereof, on any writ of execution issued hereon, may be sold upon any such
writ in whole or in part in any order desired by Payee.

 

8. Unconditional
Liability.  Maker hereby waives all notices in connection with the delivery, acceptance, performance, default, or
enforcement of the payment of this Note, and agrees that its liability shall be unconditional, without regard to the liability of any

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 Cactus Acquisition Corp. 1 Limited, a Cayman Islands exempted company (the “Company”),
and Oppenheimer & Co. (the “Representative”), as the representative of the several underwriters (the “Underwriters”),
relating to an underwritten initial public offering (the “Public Offering”) of 10,000,000 of the Company’s
units (including up to 1,500,000 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-third 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
Capital 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, Cactus Healthcare Management LP, a Delaware limited partnership
(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 24 months
from the closing of the Public Offering, 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 24 months from the closing of the Public Offering 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) held by such Sponsor or Insider. The Sponsor and each Insider hereby further waives, with respect
to the Founder Shares (including any Class A ordinary shares issuable upon conversion thereof) 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 24 months from the date
of the closing of the Public Offering 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 1,500,000 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 375,000 multiplied by a fraction, (i) the numerator of which is 1,500,000 minus the
number of Units purchased by the Underwriters upon the exercise of their over-allotment option, and (ii) the denominator of which is 1,500,000.

 

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). 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).
In connection with such increase or decrease in the size of the Public Offering, then (A) the references to 1,500,000 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 375,000 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).

 

    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)
The Sponsor and each Insider agrees that it, he or she shall not Transfer any Founder Shares (or Class A ordinary shares issuable upon
conversion thereof) held by such Sponsor or Insider until the earlier of (A) six months after the completion of the Company’s initial
Business Combination or (B) the date on which the Company will consummate a liquidation, merger, amalgamation, share exchange, reorganization,
or other similar transaction after initial Business Combination 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”),
provided, however, that the Sponsor and each Insider may Transfer during the Founder Shares Lock-up Period up to 50% of the Founder Shares
(or Class A ordinary shares issuable upon conversion thereof) held by the Sponsor or such Insider if following the completion of the Company’s
initial Business Combination the last reported sale price of the Class A ordinary shares equals or exceeds $12.00 per share (as adjusted
for share splits, share dividends, rights issuances, subdivisions, reorganizations, recapitalizations and the like) for any 20 trading
days within any 30-trading day period.

 

(b) The
Sponsor and each Insider agrees that it, he or she shall not Transfer any Private Placement Warrants (or Class A ordinary shares issued
or issuable upon the exercise of the Private Placement Warrants), until thirty (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 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 (f) or with
the Company’s prior consent, 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.
