ONE CLASS A ORDINARY SHARE AND ONE-HALF OF ONE REDEEMABLE


 


WARRANT TO PURCHASE
ONE CLASS A ORDINARY SHARE


 


THIS CERTIFIES that [●]
is the owner of [●] Units.


 


Each Unit ("Unit")
consists of one (1) Class A ordinary share, par value $0.0001 per share ("Ordinary Shares"), of Global Technology Acquisition
Corp. I, a Cayman Islands exempted company (the "Company"), and one-half (0.5) of one redeemable warrant (each
whole warrant, a "Warrant"). Each Warrant entitles the holder to purchase one (1) Ordinary Share for $11.50 per share
(subject to adjustment). Each Warrant will become exercisable on the later of (i) thirty (30) days after the Company’s completion
of a merger, share exchange, asset acquisition, share purchase, reorganization or other similar business combination with one or more
businesses (each, a "Business Combination"), and (ii) twelve (12) months from the closing of the Company’s initial
public offering, and will expire unless exercised before 5:00 p.m., New York City Time, on the date that is five (5) years after the date
on which the Company completes its initial Business Combination, or earlier upon redemption or liquidation (the "Expiration Date").
The Ordinary Shares and Warrants comprising the Units represented by this certificate are not transferable separately prior to [●],
2021, unless Citigroup Global Markets Inc. and Goldman Sachs & Co. LLC elect to allow earlier separate trading, subject to the Company’s
filing with the Securities and Exchange Commission of a Current Report on Form 8-K containing an audited balance sheet reflecting the
Company’s receipt of the gross proceeds of the initial public offering and issuing a press release announcing when separate trading
will begin. No fractional warrants will be issued upon separation of the Units and only whole warrants are exercisable. The terms of the
Warrants are governed by a Warrant Agreement, dated as of [●], 2021, between the Company and Continental Stock Transfer & Trust
Company, as Warrant Agent, and are subject to the terms and provisions contained therein, all of which terms and provisions the holder
of this certificate consents to by acceptance hereof. Copies of the Warrant Agreement are on file at the office of the Warrant Agent at
1 State Street, 30th Floor, New York, New York 10004, and are available to any Warrant holder on written request and without cost.


 


Upon the consummation
of the Business Combination, the Units represented by this certificate will automatically separate into the Class A Ordinary Shares and
Warrants comprising such Units.

holders of the Ordinary Shares the right to have their shares redeemed in connection with the Company’s initial business
combination or to redeem 100% of the Ordinary Shares if the Company does not complete its initial business combination within the
time period set forth therein, or (B) with respect to any other provision relating to the rights of holders of the Ordinary Shares,
or (iii) if the holder(s) seek(s) to redeem for cash his, her or its respective Ordinary Shares in connection with a tender offer
(or proxy solicitation, solely in the event the Company seeks shareholder approval of the proposed initial business combination)
setting forth the details of a proposed initial business combination. In no other circumstances shall the holder(s) have any right
or interest of any kind in or to the trust account.
