      Re:   Initial Public Offering

Gentlemen:

            The undersigned stockholder, officer and director of China Unistone
Acquisition Corporation ("Company"), in consideration of EarlyBirdCapital, Inc.
("EBC") entering into a letter of intent ("Letter of Intent") to underwrite an
initial public offering of the securities of the Company ("IPO") and embarking
on the IPO process, hereby agrees as follows (certain capitalized terms used
herein are defined in paragraph 11 hereof):

            1. If the Company solicits approval of its stockholders of a
Business Combination, the undersigned will vote all Insider Shares owned by him
in accordance with the majority of the votes cast by the holders of the IPO
Shares.

            2. In the event that the Company fails to consummate a Business
Combination within 18 months from the effective date ("Effective Date") of the
registration statement relating to the IPO (or 24 months under the circumstances
described in the prospectus relating to the IPO), the undersigned will take all
reasonable actions within his power to cause the Company to liquidate as soon as
reasonably practicable. The undersigned hereby waives any and all right, title,
interest or claim of any kind in or to any distribution of the Trust Fund (as
defined in the Letter of Intent) as a result of such liquidation with respect to
his Insider Shares ("Claim") and hereby waives any Claim the undersigned may
have in the future as a result of, or arising out of, any contracts or

Fund for any reason whatsoever. The undersigned 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,
or by any target business, but only to the extent necessary to ensure that such
loss, liability, claim, damage or expense does not reduce the amount in the
Trust Fund (as defined in the Letter of Intent).

            3. In order to minimize potential conflicts of interest which may
arise from multiple affiliations, the undersigned agrees to present to the
Company for its consideration, prior to presentation to any other person or
entity, any suitable opportunity to acquire an operating business, until the
earlier of the consummation by the Company of a Business Combination, the
liquidation of the Company or until such time as the undersigned ceases to be an
officer or director of the Company, subject to any pre-existing fiduciary
obligations the undersigned might have.

            4. The undersigned acknowledges and agrees that the Company will not
consummate any Business Combination which involves a company which is affiliated
with any of the Insiders unless the Company obtains an opinion from an
independent investment banking firm reasonably acceptable to EBC that the
business combination is fair to the Company's stockholders from a financial
perspective.

            5. 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 for services rendered to the Company prior
to the consummation of the Business Combination; provided that the undersigned
shall be entitled to reimbursement from the Company for his out-of-pocket
expenses incurred in connection with seeking and consummating a Business
Combination.

            6. Neither the undersigned, any member of the family of the
undersigned, or any Affiliate of the undersigned will be entitled to receive or
accept a finder's fee or any other compensation in the event the undersigned,
any member of the family of the undersigned or any Affiliate of the undersigned
originates a Business Combination.

            7. The undersigned will escrow his Insider Shares for the three year
period commencing on the Effective Date subject to the terms of a Stock Escrow
Agreement which the Company will enter into with the undersigned and an escrow
agent
