                  Re:  Initial Public Offering

Gentlemen:

                  The undersigned stockholder, officer and director of
InterAmerican Acquisition Group Inc. ("Company"), in consideration of Rodman &
Renshaw, LLC ("Rodman") 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 12 hereof):

                  1. If the Company solicits approval of its stockholders of a
Business Combination, the undersigned will vote all Insider Shares owned by him
and all shares of Common Stock of the Company acquired by him in the IPO or
aftermarket 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 (such later date
being referred to herein as the "Termination Date"), the undersigned shall (i)
take all such action reasonably within its power as is necessary to (a) dissolve
the Company and liquidate the Trust Fund to holders of IPO Shares as soon as
reasonably practicable, and after approval of the Company's stockholders and
subject to the requirements of the Delaware General Corporation Law (the "GCL"),
including voting for the adoption of a resolution by the board of directors,
prior to such Termination Date, pursuant to Section 275(a) of the GCL, which
shall deem the dissolution of the Company advisable and (b) cause to be prepared
such notices as are required by said Section 275(a) of the GCL as promptly
thereafter as possible, and (ii) vote his shares in favor of any plan of
dissolution and distribution recommended by the Company's board of directors. If
the Company does not consummate a Business Combination by the Termination Date,
the undersigned hereby agrees, with respect to any plan of dissolution and
distribution, to take all such action reasonably within its power to (x) cause
the board of directors to convene, adopt a plan of dissolution and distribution,






which the undersigned will vote to recommend to stockholders, and (y) on such
date cause the Company to prepare and file a proxy statement with the Securities
and Exchange Commission (the "SEC") setting out the plan of dissolution and
distribution. If the Company seeks approval from its stockholders to consummate
a Business Combination within 90 days of the expiration of 24 months from the
Effective Date, the undersigned agrees to take all such action reasonably within
its power to ensure that the proxy statement related to such Business
Combination will also seek stockholder approval for the plan of dissolution and
distribution in the event the stockholders do not approve the Business
Combination. If no proxy statement seeking the approval of the stockholders for
a Business Combination has been filed within 30 days prior to the date which is
24 months from the date of the IPO, the undersigned agrees, prior to such date
to take all such action reasonably within its power as is necessary to convene
and adopt a plan of dissolution and distribution and on such date file a proxy
statement with the SEC seeking stockholder approval for such plan. 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) 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 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. In the event of the liquidation of the
Trust Fund, the undersigned and William C. Morro, the Company's chief executive
officer, chief financial officer and chairman of the Company's board of
directors, agree that they, severally (but not jointly), and only up to their
respective percentage beneficial ownership interests in the Company prior to the
IPO (the undersigned owns 36% and William C. Morro owns 54% of the Company's
outstanding shares prior to the IPO), will 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) to which the
Company may become subject as a result of any claim by any vendor that is owed
money by the Company (which includes, for example, accountants, lawyers,
investment bankers, consultants and analysts) for services rendered or products
sold provided that the Company did not obtain a valid and enforceable waiver
from such party of its rights or claims to the Trust Fund and only to the extent
necessary to ensure that such loss, liability, claim, damage or expense does not
reduce the amount in the Trust Fund.

                  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.



                  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.

                  5. Neither the undersigned, any member of the family of the
undersigned, nor any affiliate ("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. Notwithstanding
the foregoing to the contrary, the undersigned 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 commencing
on the Effective Date, InterAmerican Advisors, LLC ("Related Party"), shall be
allowed to charge the Company $10,000 per month, representing an allocable share
of Related Party's overhead, to compensate it for the Company's use of Related
Party's offices, utilities and personnel.

                  6. Neither the undersigned, any member of the family of the
undersigned, nor 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 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.

                  8. The undersigned agrees to be Chief Operating Officer and
Secretary of the Company and a member of the Company's board of directors until
the earlier of the consummation by the Company of a Business Combination or the
liquidation of the Company. The undersigned's biographical information furnished
