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), Stockholder will
vote all Insider Shares owned by it in favor of the Company's decision to
liquidate. Each of Stockholder and each controlling person of Stockholder (each

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

                  4. Neither Stockholder, any Control Person, nor any affiliate
of Stockholder or any Control Person ("Affiliate") 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; provided that commencing on the
Effective Date, Katalyst LLC ("Related Party"), shall be allowed to charge the
Company $7,500 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. Related Party and Stockholder shall also be entitled to
reimbursement from the Company for their out-of-pocket expenses incurred in
connection with seeking and consummating a Business Combination.

                  5. Neither Stockholder, any Control Person, nor any Affiliate

Affiliate of the undersigned originates a Business Combination.

                  6. Stockholder 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 Stockholder and an
escrow agent acceptable to the Company.

EBC and annexed as Exhibit A hereto is true and accurate in all respects.
Stockholder represents and warrants that no Control Person:

     (a) is subject to, or a respondent in, any legal action for, any
injunction, cease-and-desist order or order or stipulation to desist or refrain
from any act or practice relating to the offering of securities in any
jurisdiction;

     (b) has never been convicted of or pleaded guilty to any crime (i)
involving any fraud or (ii) relating to any financial transaction or handling of
funds of another person, or (iii) pertaining to any dealings in any securities
and is not currently a defendant in any such criminal proceeding; and

     (c) has never been suspended or expelled from membership in any securities
or commodities exchange or association or had a securities or commodities

                  8. Stockholder has full right and power, without violating any

agreement by which it is bound, to enter into this letter agreement.

                  9. This letter agreement shall be governed by and construed
and enforced in accordance with the laws of the State of New York, without
giving effect to conflicts of law principles that would result in the
application of the substantive laws of another jurisdiction. Stockholder hereby
(i) agrees that any action, proceeding or claim against him arising out of or
relating in any way to this letter agreement (a "Proceeding") shall be brought
and enforced in the courts of the State of New York of the United States of

to such exclusive jurisdiction and that such courts represent an inconvenient

agent is unable to act as such, Stockholder will promptly notify the Company and
EBC and appoint a substitute agent acceptable to each of the Company and EBC
within 30 days and nothing in this letter will affect the right of either party
to serve process in any other manner permitted by law.

acquisition by merger, capital stock exchange, asset or stock acquisition,
reorganization or otherwise, of an operating business; (ii) "Insiders" shall
