           Re:   Initial Public Offering

Ladies and Gentlemen:

     The undersigned stockholder, officer and director of Trinity Partners
Acquisition Company Inc. ("Company"), in consideration of HCFP/Brenner
Securities LLC ("Brenner")'s willingness 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. In the event that the Company fails to consummate a Business Combination
within 12 months from the effective date ("Effective Date") of the registration
statement relating to the IPO (or 18 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 Trust Fund to be liquidated and
distributed to the holders of the IPO Shares no later than 60 days from the
Effective Date. The undersigned waives any and all right, title, interest or
claim of any kind in or to any distribution of the Trust Fund as a result of
such liquidation with respect to his Insider Shares ("Claim") and hereby waives
any Claim he 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.

     2. 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
Trust Fund 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.

     3. 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 Brenner that the
business combination is fair to the Company's stockholders from a financial
perspective.

     4. 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. The undersigned shall also be entitled
to reimbursement from the Company for his out-of-pocket expenses incurred in
connection with seeking and consummating a Business Combination.

     5. 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.

     6. The undersigned hereby agrees and acknowledges that (i) Brenner would be
irreparably injured in the event of a breach by the undersigned of any of his
obligations under this paragraph 6, (ii) monetary damages would not be an
adequate remedy for any such breach, and (iii) Brenner shall be entitled to
injunctive relief, in addition to any other remedy it may have, in the event of
such breach.

     7. The undersigned agrees not to sell any of his Insider Securities until
the earlier of the Company's completion of a Business Combination or the
distribution of the Trust Fund.

     8. I agree to be a director of the Company until the earlier of the
consummation by the Company of a Business Combination or the distribution of the
Trust Fund. The undersigned's biographical information furnished to the Company
and Brenner and attached hereto as Exhibit A is true and accurate in all
respects, does not omit any material information with respect to the
undersigned's background and 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 furnished to the Company
