	 	Re:	Initial Public Offering

 

Gentlemen:

 

This
letter is being delivered to you in accordance with the Underwriting Agreement (the “Underwriting Agreement”)
entered into by and between East Stone Acquisition Corporation, a British Virgin Islands company (the “Company”),
and I-Bankers Securities Inc., as Representative (the “Representative”) of the several Underwriters
named in Schedule A thereto (the “Underwriters”), relating to an underwritten initial public offering
(the “IPO”) of the Company’s units (the “Units”), each comprised of
one ordinary share, no par value, of the Company (the “Ordinary Shares”) and one redeemable warrant
(the “Warrant”) to purchase one-half of one Ordinary Share and one right to receive one-tenth (1/10)
of one Ordinary Share upon the consummation of the Company’s initial business combination (the “Right”).
Certain capitalized terms used herein are defined in paragraph 17 hereof.

 

In
order to induce the Company and the Underwriters to enter into the Underwriting Agreement and to proceed with the IPO, and in
recognition of the benefit that such IPO will confer upon the undersigned as a shareholder or officer or director of the Company,
and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the undersigned hereby
agrees with the Company as follows:

 

1. If the Company solicits approval of its shareholders of a Business Combination (as defined below), the undersigned will
vote all Ordinary Shares beneficially owned by him, her or it, whether acquired before, in or after the IPO, or whether such Ordinary
Shares are underlying the Private Units, in favor of such Business Combination.

 

2. (a) In the event that the Company fails to consummate a Business Combination within the time period set forth in the
Company’s Amended and Restated Memorandum and Articles of Association, as the same may be amended from time to time, the
undersigned shall take all reasonable steps to (i) cause the Trust Fund to be liquidated and distributed to the holders of IPO
Shares and (ii) cause the Company to liquidate as soon as reasonably practicable.

 

(b)
The undersigned hereby waives any and all right, title, interest or claim of any kind (“Claim”) in,
or, with respect to his, her or its Insider Shares or Private Units, to any distribution of, the Trust Fund. The undersigned hereby
waives any Claim the undersigned may have in the future as a result of, or arising out of, any contracts or agreements with the
Company and will not seek recourse against the Trust Fund for any reason whatsoever. The undersigned acknowledges and agrees that
there will be no distribution from the Trust Fund with respect to any Warrants, which will terminate on the Company’s liquidation.

 

(c)
In the event of the liquidation of the Trust Fund, Double Ventures Holdings Limited (“Sponsor”) agrees
to indemnify and hold harmless the Company against any and all loss, liability, claims, 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) which the Company may become subject as a result of any claim
by any vendor or other person who is owed money by the Company for services rendered or products sold to or contracted for the
Company, or by any target business with which the Company has discussed entering into a transaction agreement, but only to the
extent necessary to ensure that such loss, liability, claim, damage or expense does not reduce the amount of funds in the Trust
Fund to below $10.00 per IPO Share; provided that such indemnity shall not apply if such vendor or other person
executes a waiver of any and all rights to seek access to the Trust Account and except as to claims under the Company’s
indemnity of the underwriters of the IPO against certain liabilities.

 

     

     

    

 

3.
(a) The Initial Shareholders agree that they shall not Transfer any Insider Shares: (x) with respect to 50% of its Insider Shares,
until the earlier of (i) six (6) months after the date of the consummation of the Business Combination or (ii) the date on which
the closing price of the Ordinary Shares equals or exceeds $12.50 per share (as adjusted for stock splits, stock dividends, reorganizations
and recapitalizations) for any 20 trading days within any 30-trading day period commencing after the Business Combination; and
(y) with respect to the remaining 50% of their Insider Shares, six (6) months after the date of the consummation of the Business
Combination, or earlier, in either case, if, subsequent to the Business Combination, the Company consummates a subsequent liquidation,
merger, stock exchange or other similar transaction which results in all of the Company’s shareholders having the right
to exchange their Ordinary Shares for cash, securities or other property.

 

(b)
The Sponsor and Anchor Investors agree that they shall not effectuate any Transfer of securities issued or issuable upon the exercise
of the Private Units or their underlying securities until 30 days after the completion of the Business Combination.

 

(c)
Notwithstanding the provisions set forth in paragraphs 3(a) and (b), Transfers of the Insider Shares, securities issued or issuable
upon the exercise of the Private Units or their underlying securities, and that are held by the Sponsor, any Insider or any of
their permitted transferees (that have complied with this paragraph 3(c)), are permitted: (1) to any persons (including their
affiliates and shareholders) participating in the private placement of the Private Units, officers, directors, shareholders, employees
and members of the Sponsor and its affiliates, (2) amongst insiders or to the Company’s officers, directors and employees,
(3) if a holder is an entity, as a distribution to its, partners, shareholders or members upon its liquidation, (4) by bona fide
gift to a member of the holder’s immediate family or to a trust, the beneficiary of which is a holder or a member of a holder’s
immediate family, for estate planning purposes, (5) by virtue of the laws of descent and distribution upon death, (6) pursuant
to a qualified domestic relations order, (7) by certain pledges to secure obligations incurred in connection with purchases of
the Company’s securities, (8) by private sales at prices no greater than the price at which the applicable securities were
originally purchased or (9) to the Company for no value for cancellation in connection with the consummation of the Business Combination,
in each case (except for clause 9) where the transferee agrees to the terms of this letter agreement and by the same agreements
entered into by the Sponsor with respect to such securities.

 

4. [Intentionally Omitted].

 

5. In order to minimize potential conflicts of interest which may arise from multiple affiliations, the undersigned directors
and officers of the Company agree to present to the Company for its consideration, prior to presentation to any other person or
entity, any suitable opportunity to acquire a target business, until the earlier of the consummation by the Company of a Business
Combination or the liquidation of the Company, subject to any pre-existing fiduciary and contractual obligations the undersigned
directors and officers might have.

 

6. The undersigned acknowledges and agrees that prior to entering into a Business Combination with a target business that is
affiliated with any Insiders of the Company or their affiliates, such transaction must be approved by a majority of the Company’s
disinterested independent directors and the Company must obtain an opinion from an independent investment banking firm or independent
accounting firm that such Business Combination is fair to the Company’s unaffiliated shareholders from a financial point
of view.

 

7. Neither the undersigned, any member of the family of the undersigned, nor any affiliate of the undersigned will be entitled
to receive and will not accept any compensation or other cash payment for services rendered prior to, or in order to effectuate,
the consummation of the Business Combination; provided that the Company shall be allowed to (i) repay working
capital loans made by the undersigned or its affiliates to the Company in cash upon consummation of the Business Combination or,
at the undersigned’s discretion, with respect to up to an aggregate of $1,500,000 of working capital loans from all lenders,
by converting such loans into Private Units at a price of $10.00 per Private Unit, as more fully described in the Registration
Statement, (ii) repay non-interest bearing loans and advances in an aggregate amount of $285,671 made to the Company by the Initial
Shareholders to cover the IPO expenses, (iii) pay up to $120,000 per month to an affiliate of the Company’s executive officers
for office space and related services, as more fully described in the Registration Statement, and (iv) reimburse the undersigned
and any affiliate of the undersigned for their out-of-pocket expenses incurred in connection with identifying, investigating and
consummating a Business Combination.

8. Neither any undersigned officer or director, any member of the family of any undersigned officer or director, nor any affiliate
of any undersigned officer or director will be entitled to receive or accept a finder’s fee or any other compensation in
the event any undersigned officer or director, any member of the family of any undersigned officer or director or any affiliate
of any undersigned officer or director originates a Business Combination.

 

9. The undersigned officers and directors agree to be the officers and directors of the Company until the earlier of the consummation
by the Company of a Business Combination, the liquidation of the Company or such officer or director is officially replaced by
