                  Re:      Initial Public Offering

Gentlemen:

                  Asia Development Capital LLC ("ADC"), a stockholder of Asia
Automotive Acquisition Corporation("Company"), in consideration of Rodman &
Renshaw, LLC ("Rodman & Renshaw") 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 10 hereof):

                  1. If the Company solicits approval of its stockholders of a
Business Combination, ADC will vote all Insider Shares owned by it 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), ADC will vote
all Insider Shares owned by it in favor of the Company's decision to liquidate.
Each of ADC and each member or controlling person of ADC (each a "Control
Person") 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)
and any remaining net assets of the Company as a result of such liquidation with
respect to its Insider Shares ("Claim") and hereby waives any Claim either 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.

                  3. ADC 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 Rodman & Renshaw
that the business combination is fair to the Company's stockholders from a
financial perspective.

                  4. Neither ADC, any Control Person, nor any affiliate
("Affiliate") of ADC or any Control Person 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. Notwithstanding the foregoing to the
contrary, ADC shall be entitled to reimbursement from the Company for its
out-of-pocket expenses incurred in connection with seeking and consummating a
Business Combination and shall be allowed to receive from the Company $7,500 per
month, representing an allocable share of ADC's overhead, to compensate it for
the Company's use of ADC's offices, utilities and personnel.

                  5. Neither ADC, any Control Person, nor any Affiliate of ADC
will be entitled to receive or accept a finder's fee or any other compensation
in the event ADC, any Control Person or any Affiliate originates a Business
Combination.

                  6. ADC will escrow its 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 acceptable to the Company.

                  7. ADC's Questionnaire furnished to the Company and Rodman &

undersigned will promptly notify the Company and Rodman & Renshaw and appoint a
substitute agent acceptable to each of the Company and Rodman & Renshaw within
