PROMISSORY NOTE

Global Technology Acquisition Corp. I, a Cayman Islands exempted company limited by shares and blank check company (the “Maker”), promises to pay to the order of HCG Opportunity II, LLC, a Delaware limited liability company, or its registered assigns or successors in interest (the “Payee”), or order, the principal sum of up to Two-Million Five-Hundred Thousand U.S. Dollars (U.S. $2,500,000) (as set forth on the Schedule of Borrowings attached hereto) 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 funds or as otherwise determined by the Maker to such account as the Payee may from time to time designate by written notice in accordance with the provisions of this Note.

1. Principal. The principal balance of this Note shall be due and payable by the Maker on the earlier of: (i) the date on which the Maker consummates its initial business combination (the “Business Combination”) and (ii) the date the Maker liquidates the Trust Account (as defined in the Maker’s Second Amended and Restated Memorandum and Articles of Association in effect on the date this Note was originally issued) upon the failure of the Maker to consummation the Business Combination within the time period set forth in the Maker’s Second Amended and Restated Memorandum and Articles of Association (such date, the “Maturity Date”), unless accelerated upon the occurrence of an Event of Default (as defined below) or extended by mutual agreement of Maker and Payee. Maker may from time to time prepay the outstanding principal amount of this Note in whole or in part without premium or penalty at any time prior to the Maturity Date without premium or penalty by providing notice to Payee of such prepayment no later than 11:00 a.m. Pacific Standard Time on the business day on which Maker wishes to make such prepayment. Once given, notices of prepayment shall be irrevocable.

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

3. Drawdown Requests. Maker and Payee agree that Maker may request up to the principal amount of this Note for costs reasonably related to Maker’s working capital purposes and/or to finance additional deposits into the Maker’s Trust Account in connection with the extension of the date by which the Maker must consummate the Business Combination as set forth in the Maker’s Second Amended and Restated Memorandum and Articles of Association. The 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. Payee shall fund each Drawdown Request no later than five (5) business days after receipt of a Drawdown Request; provided, however, that the maximum amount of drawdowns collectively under this Note is Two-Million Five-Hundred Thousand U.S. Dollars (U.S. $2,500,000). Once an amount is drawn under this Note, it shall not be available for future Drawdown Requests even if prepaid. Upon completion of any draw down, the Schedule of Borrowings attached hereto shall be updated to reflect such draw down. No fees, payments or other amounts shall be due to Payee in connection with, or as a result of, any Drawdown Request by Maker. Notwithstanding the foregoing, all payments shall be applied in accordance with Section 5 hereof.

4. Optional Conversion.

(a) Upon consummation of the Business Combination and at the Payee’s option, the Payee may elect, by written notice to the Maker, to convert all or any portion of this Note into that number of warrants (the “Conversion Warrants”) to purchase a number of Class A ordinary shares, par value U.S. $0.0001 per share, of the Maker equal to: (i) the portion of the principal amount of the Note being converted pursuant to this Section 4, divided by (ii) U.S. $1.00. The Conversion Warrants shall be identical to the warrants issued by the Maker to Global Technology Acquisition I Sponsor LP, a Delaware limited liability company (“Original Sponsor”), in a private placement upon the consummation of Maker’s initial public offering (the “IPO”). The Conversion Warrants and their underlying securities, and any other equity security of Maker issued or issuable with respect to the foregoing by way of a share dividend or share split or in connection with a combination of shares recapitalization, amalgamation, merger, consolidation or reorganization, shall be entitled to registration rights on the same terms as the registration rights set forth in that certain Registration Rights Agreement, dated as of October 20, 2021, by and among the Maker, Original Sponsor and the other parties thereto.

(b) Upon any complete or partial conversion of the principal amount of this Note (i) such principal amount shall be so converted and such converted portion of this Note shall become fully paid and satisfied, (ii) the Payee shall surrender and deliver this Note, duly endorsed, to Maker or such other address which Maker shall designate against delivery of the Conversion Warrants, (iii) Maker shall promptly deliver a new duly executed Note to the Payee in the principal amount that remains outstanding, if any, after any such conversion and (iv) in exchange for all or any portion of the surrendered Note described in Section 4(a), Maker shall, at the direction of Payee, deliver to Payee (or its members or their respective affiliates) (Payee or such other persons, the “Holders”) the Conversion Warrants, which shall bear such legends as are required, in the opinion of counsel to Maker or by any other agreement between Maker and the Payee and applicable state and federal securities laws.

(c) The Holders shall pay any and all issue and other taxes that may be payable with respect to any issue or delivery of the Conversion Warrants upon conversion of this Note pursuant hereto; provided, however, that the Payee shall pay any transfer taxes resulting from any transfer requested by the Holders in connection with any such conversion.

(d) The Conversion Warrants shall not be issued upon conversion of this Note unless such issuance and such conversion comply with all applicable provisions of law.

5. 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 attorneys’ fees, then to the payment in full of any late charges and finally to the reduction of the unpaid principal balance of this Note.
