     Re: Initial Public Offering
         -----------------------

Gentlemen:

     The undersigned stockholder and officer of Geneva Acquisition Corporation
("Company"), in consideration of Ladenburg Thalmann & Co. Inc. ("Ladenburg")
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 14 hereof):

1.   If the Company solicits approval of its stockholders of a Business
Combination, the undersigned will vote all Insider Shares owned by him 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 24 months from the effective date ("Effective Date") of the registration
statement relating to the IPO, the undersigned will (i) cause the Trust Fund (as
defined in the Letter of Intent) to be liquidated and distributed to the holders
of IPO Shares and (ii) take all reasonable actions within his power to cause the
Company to liquidate as soon as reasonably practicable. The undersigned hereby
waives any and all right, title, interest or claim of any kind in or to any
distribution of the Trust Fund and any remaining net assets of the Company as a
result of such liquidation with respect to his 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 agrees to 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) which
the Company may become subject as a result of any claim by any vendor or other
person who is owed money by the Company for services rendered or products sold
or contracted for, 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.

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 (meaning the acquisition of at
least a majority interest in an operating business) which

may reasonably be required to be presented to the Company under Delaware Law,
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, subject to any pre-existing fiduciary
and contractual obligations the undersigned might have.

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 unless the Company obtains an opinion from an
independent investment banking firm reasonably acceptable to Ladenburg that the
business combination is fair to the Company's stockholders from a financial
perspective.

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 or in connection with the consummation of the Business
Combination; provided that the undersigned shall be entitled to reimbursement
from the Company for his out-of-pocket expenses incurred in connection with
seeking and consummating a Business Combination.

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 all of his Insider Shares acquired prior to the
IPO until six months after the Company consummates a Business Combination,
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 the Treasurer of the Company 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 to the
Company and Ladenburg 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 Item 401 of Regulation S-K, promulgated under the
Securities Act of 1933. The undersigned's Questionnaire furnished to the Company
and Ladenburg and annexed as Exhibit B hereto is true and accurate in all
respects. The undersigned represents and warrants that:

Combination.

violating the undersigned's right of privacy in any manner in requesting and
obtaining the Information and the undersigned hereby releases them from
liability for any damage whatsoever in that connection.

13.  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.

14.  As used herein, (i) a "Business Combination" shall mean an acquisition by
