Re: Initial Public Offering


 


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 among Global Blockchain Acquisition Corp., a Delaware corporation (the “Company”)
and I-Bankers Securities, Inc. as the underwriter (the “Underwriter”), relating to an underwritten initial public
offering (the “Public Offering”), of up to 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 share of
the Company’s common stock, par value $0.0001 per share (the “Common Stock”), one right, and one redeemable
warrant. Each whole right (each a “Right”) entitles the holder thereof to receive one-tenth (1/10) of one share
of Common Stock upon the consummation of an initial business combination. Each warrant (each, a “Warrant”) entitles
the holder thereof to purchase one share of Common Stock at a price of $11.50 per share, subject to adjustment. The Units 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 Securities and Exchange Commission (the “Commission”) and the Units have been
approved to be 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, Global Blockchain Sponsor, LLC (the “Sponsor”)
and each of the undersigned individuals, each of whom is a member of the Company’s board of directors and/or management team and
the Underwriters, solely in their capacity as a security holder of the Company, (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 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 Capital Stock 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
engages in a tender offer in connection with any proposed Business Combination, each Insider agrees that it, he or she will not seek to
sell its, his or her shares of Common Stock to the Company in connection with such tender offer.


 






     


     


    

 


2. The Sponsor and each Insider
hereby agrees that in the event that the Company fails to consummate a Business Combination within 15 months from the closing of the Public
Offering (or up to 21 months from the closing of this offering if the Company extends the period of time to consummate a business combination),
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 Common Stock 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 its taxes (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 Stockholders’ rights as stockholders of the Company (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 stockholders and the Company’s board of directors, dissolve
and liquidate, 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 agree not to propose any amendment to the Company’s amended and restated
certificate of incorporation (the “Charter”) that would modify (i) 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 15 months from the closing
of the Public Offering (or up to 21 months from the closing of this offering if the Company extends the period of time to consummate a
business combination) or (ii) the other provisions relating to stockholders’ rights or pre-initial business combination activities,
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 (which interest
shall be net of amounts released for payment of taxes) divided by the number of then outstanding Offering Shares. The Sponsor and each
Insider agree to waive its redemption rights with respect to shares of Common Stock owned by it in connection with a stockholder vote
to approve an amendment to the Company’s Charter (A) 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 15 months from the closing of the Public
Offering (or up to 21 months from the closing of this offering if the Company extends the period of time to consummate a business combination)
or (B) with respect to any other provision relating to stockholders’ rights or pre-initial business combination activity.


 


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 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 in the context of a tender offer made by the Company
to purchase shares of Common Stock (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
15 months from the date of the closing of the Public Offering (or up to 21 months from the closing of this offering if the Company extends
the period of time to consummate a business combination)).


 


3. 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
(the “Exchange Act”), and the rules and regulations of the Commission promulgated thereunder, with respect
to any Units, shares of Capital Stock, Warrants or any securities convertible into, or exercisable, or exchangeable for, shares of 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 any Units, shares of Capital Stock, Warrants or any securities convertible into, or exercisable,
or exchangeable for, shares of 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). 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 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 paragraph will not apply
if (i) the release or waiver is effected solely to permit a transfer of securities that is not for consideration and (ii) 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, the Sponsor (which for purposes of clarification shall not extend to any other stockholders, 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 accountants) 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 for 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) $10.15 per Offering Share or (ii) such lesser amount per Offering Share held in the
Trust Account as of the date of the liquidation of the Trust Account, due to reductions in the value of the trust assets, 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.


 


5. To the extent that the
Underwriters do not exercise their over-allotment option to purchase up to an additional 2,250,000 Units within 30 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 562,500. The forfeiture will be adjusted to the extent that the over-allotment option is not exercised in full
by the Underwriters so that the Initial Stockholders will own an aggregate of 20.0% of the Company’s issued and outstanding shares
of Capital Stock after the Public Offering (excluding the up to 390,000 representative shares (or up to 450,000 shares if the underwriters’
over-allotment option is exercised in full)).


 


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 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.


 






    -3- 


     


    

 


7. (a) The Sponsor and each
Insider agrees that it, he or she shall not Transfer any Founder Shares until the earlier of (A) one year after the completion of
the Company’s initial Business Combination or (B) subsequent to the Company’s initial Business Combination, (x) if the
last sale price of the Common Stock equals or exceeds $12.00 per share (as adjusted for stock splits, stock dividends, reorganizations,
recapitalizations and the like) for any 20 trading days within any 30-trading day period commencing at least 150 days after the consummation
of 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 Common Stock for cash, securities or other property.


 


(b) The Sponsor and each Insider
agrees that it, he or she shall not Transfer any Private Placement Warrants (or shares of Common Stock issued or issuable upon the exercise
of the Private Placement Warrants) until 30 days after the completion of a Business Combination.


 


(c) Notwithstanding the provisions
set forth in paragraphs 7(a) and (b), Transfers of the Founder Shares, Private Placement Warrants, and shares of Common Stock issued
or issuable upon the exercise of the Private Placement Warrants that are held by the Sponsor, any Insider or any of their permitted transferees
(that have complied with this paragraph 7(c)), are permitted (i) to the Company’s officers or directors, any affiliates or
family members of any of the Company’s officers or directors, any affiliates of the Sponsor, any members of the Sponsor, or any
of their affiliates, officers, directors, direct and indirect equityholders; (ii) in the case of an individual, 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; (iii) in the case of an individual, transfers by virtue of laws
of descent and distribution upon death of the individual; (iv) in the case of an individual, transfers pursuant to a qualified domestic
relations order; (v) 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 shares were originally purchased; (vi) in case of an entity, as a distribution to its partners,
shareholders, officers or members upon its liquidation; and (vii) by virtue of the laws of the State of Delaware or the Sponsor’s
limited liability company agreement upon dissolution of the Sponsor; provided, however, that in the case of clauses (i) through (vii),
these permitted transferees must enter into a written agreement agreeing to be bound by the restrictions herein.


  


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 the 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 Insider nor any affiliate of the Sponsor or any Insider, nor any director or officer of the
Company, shall receive from the Company any finder’s fee, reimbursement, consulting fee, 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 $600,000 made to the Company by the Sponsor; payment to [●] for a total of $5,000 per month; reimbursement
for any out-of-pocket expenses related to identifying, investigating 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 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 warrants at a price of $1.00 per warrant at the option of the lender. Such warrants would be identical
to the Private Placement Warrants, including as to exercise price, exercisability and exercise period.
