East
Stone Acquisition Corporation, a British Virgin Islands business company and blank check company (the “Maker”), promises
to pay to the order of ICONIQ Holding Limited, an exempted company incorporated in the Cayman Islands with limited liability, or its
permitted assigns or successors in interest (the “Payee” or “Lender”), the principal sum of ONE
MILLION U.S. Dollars ($1,000,000) or such lower amount as defined under Section 2 hereof, with no interest bearing, in lawful money of
the United States of America, on the terms and conditions described below. 


 


1.
Lending. This Note shall be issued to the Lender and exercised in two tranches, provided in each case that the Maker has notified
the Lender in writing of its designated bank account details in advance no less than three (3) business days prior to the funding date:


 


(a)
First Tranche. THREE HUNDRED THOUSAND US DOLLARS ($300,000) shall be paid to the bank account designated by and opened
in the name of the Maker within five (5) calendar days after the entry by the Lender and the Maker into this Note.


 


(b)
Second Tranche. Up to SEVEN HUNDRED THOUSAND US DOLLARS ($700,000) shall be directly disbursed in one or more payments
to independent and reputable third-party service providers engaged by the Maker solely in relation to the consummation of the contemplated
business combination between the Maker and the Payee (“Business Combination”); provided that before each disbursement,
the Maker shall furnish an official payment request in writing to the Lender setting out in reasonable detail the services that have
been provided by the third-party provider (which services shall comply with the foregoing sentence of this Section 1(c)), the amount
due to the third-party provider that corresponds to such services, and the due date for payment, attached with the photocopy of invoices
issued by such third-party providers for the Lender to review; provided further that the date of each official payment request
shall be no later than ten (10) business days prior to the due date for payment set forth therein. The Lender shall make such payments
within ten (10) business days after receiving the payment request but shall only be required to do so and in such amounts with respect
to which a payment request in compliance with the foregoing proviso reasonably satisfactory to it has been provided to it; provided
that, for the avoidance of doubt, the aggregate amount to be made by the Lender under this Section 1(c) shall not exceed US$700,000.


 


2.
Principal. The aggregate amount paid to the Maker’s designated bank account or to third-party service providers under
Section 1 of this Note from time to time shall be referred to as the “Principal”. The Principal shall only be used
solely for the purpose of paying for services provided by independent and reputable third-party service providers to the Maker following
the execution of the non-binding term sheet on March 15, 2022 by the Maker and the Payer which set out the key terms of the Business
Combination and directly in relation to maintaining the Maker as a public company and the consummation of the Business Combination.
