          Re: Initial Public Offering

Gentlemen:

          The undersigned stockholder and director of Renaissance Acquisition
Corp. ("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 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), 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.

          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 a
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 one year 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 a Director 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
