SUBSCRIPTION AGREEMENT

                                                              As of May 22, 2006

To the Board of Directors of
Renaissance Acquisition Corp.:

Gentlemen:

          The undersigned hereby subscribes for and agrees to purchase 2,833,333
Warrants ("Insider Warrants") at $0.60 per Insider Warrant, of Renaissance
Acquisition Corp. (the "Corporation") for an aggregate purchase price of
$1,699,999.80 ("Purchase Price"). The purchase and issuance of the Insider
Warrants shall occur simultaneously with the consummation of the Corporation's
initial public offering of securities ("IPO") which is being underwritten by
Ladenburg Thalmann & Co. Inc. ("Ladenburg"). The Insider Warrants will be sold
to the undersigned on a private placement basis and not part of the IPO.

          At least 24 hours prior to the effective date of the registration
statement filed in connection with the IPO ("Registration Statement"), the
undersigned shall deliver the Purchase Price to Graubard Miller ("GM") to hold
in a non-interest bearing account until the Corporation consummates the IPO.
Simultaneously with the consummation of the IPO, GM shall deposit the Purchase
Price, without interest or deduction, into the trust fund ("Trust Fund")
established by the Corporation for the benefit of the Corporation's public
stockholders as described in the Corporation's Registration Statement, pursuant
to the terms of an Investment Management Trust Agreement to be entered into
between the Corporation and Continental Stock Transfer & Trust Company. In the
event that the IPO is not consummated within 14 days of the Purchase Price being
delivered to GM, GM shall return the Purchase Price to the undersigned, without
interest or deduction.

          The undersigned represents and warrants that it has been advised that
the Insider Warrants have not been registered under the Securities Act; that it
is acquiring the Insider Warrants for its account for investment purposes only;
that it has no present intention of selling or otherwise disposing of the
Insider Warrants in violation of the securities laws of the United States; that
it is an "accredited investor" as defined by Rule 501 of Regulation D
promulgated under the Securities Act of 1933, as amended (the "Securities Act");
and that it is familiar with the proposed business, management, financial
condition and affairs of the Corporation.

          Moreover, the undersigned agrees that it shall not sell or transfer
the Insider Warrants until 30 days after the Corporation consummates a merger,
capital stock exchange, asset acquisition or other similar business combination
with an operating business ("Business Combination") and acknowledges that the
Insider Warrants will be held in escrow during such time period and the
certificates for such Insider Warrants shall contain a legend indicating such
restriction on transferability.

          The Corporation hereby acknowledges and agrees that, in the event the
Company calls its public Warrants for redemption pursuant to that certain
Warrant Agreement to be entered into by the Company and Continental Stock
Transfer & Trust Company in connection with the Company's IPO, the Company shall
allow the undersigned or its affiliates to exercise any Insider Warrants by
surrendering such Insider Warrants for that number of shares of Common Stock
equal to the quotient obtained by dividing (x) the product of the number of
shares of Common Stock underlying the Insider Warrants, multiplied by the
difference between the Warrant exercise price and the "Fair Market Value"
(defined below) by (y) the



Fair Market Value. The "Fair Market Value" shall mean the average reported last
sale price of the Common Stock for the 10 trading days ending on the third
trading day prior to the date on which the notice of redemption is sent to
holders of Warrants.

          The terms of this agreement and the restriction on transfers with
respect to the Insider Warrants may not be amended without the prior written
consent of Ladenburg.

                                        Very truly yours,


                                        RAC PARTNERS LLC
