        Re: Initial Public Offering

Gentlemen:

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

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

        2. In the event that CMAC 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 CMAC to liquidate. The undersigned waives any
and all rights he may have to receive any distribution of cash, property or
other assets as a result of such liquidation with respect to his Insider Shares.
The undersigned agrees to indemnify and hold harmless CMAC 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 CMAC may become subject as a result
of any claim by any vendor or other person who is owed money by CMAC 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 CMAC for its
consideration, prior to presentation to any other person or company, any
suitable opportunity to acquire an operating business, until the earlier of the
consummation by CMAC of a Business Combination, the liquidation of CMAC or until
such time as the undersigned ceases to be a director of CMAC, subject to any
pre-existing or currently planned and disclosed obligations the undersigned
might have.

        4. The undersigned acknowledges and agrees that CMAC will not consummate
any Business Combination which involves a company which is affiliated with any

banking firm that the business combination is fair to CMAC's stockholders from a
financial perspective.

        5. The undersigned will not be entitled to receive and will not accept
any compensation for services rendered to CMAC prior to the consummation of the
Business Combination; provided that the undersigned shall be entitled to
reimbursement from CMAC for his out-of-pocket expenses incurred in connection
with seeking and consummating a Business Combination

        6. The undersigned will not be entitled to receive and will not accept a
finder's fee or any other compensation from CMAC in the event 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 CMAC will enter into with the undersigned and Continental Stock
Transfer & Trust Company as escrow agent.

        8. The undersigned agrees to be the Chief Executive Officer, President
and a director of CMAC until the earlier of the consummation by CMAC of a
Business Combination or the liquidation of CMAC. The undersigned's biographical

true and accurate in all respects and such information contains all of the
information required to be disclosed pursuant to Section 401 of Regulation S-K,
promulgated under the Securities Act of 1933. The undersigned's Questionnaire

representatives or agents any information they may have about the undersigned's
finances ("Financial Information"). Neither Broadband nor its agents shall be

Broadband may provide the Financial Information to a third party if otherwise
required by law or if the Financial Information is relevant to any issue in any
action, suit or proceeding to which Broadband is a party or by which it is or
may be bound.

reorganization or otherwise, of an operating business selected by CMAC; (ii)
