                  Re: Initial Public Offering

Gentlemen:

                  The undersigned stockholder, officer and director of Great
Wall Acquisition Corporation ("GWAC"), 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 GWAC
("IPO") and embarking on the IPO process, hereby agrees as follows (certain
capitalized terms used herein are defined in paragraph 12 hereof):

                  1. If GWAC 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 GWAC 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 GWAC 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 GWAC
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 GWAC may become

subject as a result of any claim by any vendor or other person who is owed money
by GWAC 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 GWAC
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 the GWAC of a Business Combination, the liquidation of GWAC or
until such time as the undersigned ceases to be an officer or director of GWAC,
subject to any pre-existing fiduciary obligations the undersigned might have.

                  4. The undersigned acknowledges and agrees that the SPAC will
not consummate any Business Combination which involves a company which is
affiliated with any of the Insiders unless GWAC obtains an opinion from an
independent investment banking firm that the business combination is fair to
GWAC'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 GWAC prior to the
consummation of the Business Combination; provided that the undersigned shall be
entitled to reimbursement from GWAC 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 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 GWAC will enter into with the undersigned and
Continental Stock Transfer & Trust Company as escrow agent.

                  8. The undersigned agrees that, during the two year period
terminating on August 11, 2005, he will not become involved (whether as owner,
manager, operator, creditor, partner, shareholder, joint venturer, employee,
officer, director, consultant or otherwise) with any Acquisition Fund (as
defined in Section 12(v) below), unless such Acquisition Fund engages Broadband
to be the managing underwriter

of the initial public offering of the Acquisition Fund's securities.

                  The undersigned hereby agrees and acknowledges that (i)
Broadband would be irreparably injured in the event of a breach by the
undersigned of any of his obligations under this paragraph 8, (ii) monetary
damages would not be an adequate remedy for any such breach, and (iii) Broadband
shall be entitled to injunctive relief, in addition to any other remedy it may
have, in the event of such breach.

                  9. The undersigned agrees to be the Chairman of the Board,

violating any agreement by which the undersigned is bound, to enter into this
letter agreement and to serve as Chairman of the Board of Directors, Chief
Executive Officer and a director of GWAC.
