acceptable; provided, however, in no event will the
representative of the underwriters allow separate trading of the Common Stock
and Warrants until the Company files, with the Securities and Exchange
Commission, an audited balance sheet reflecting the Company’s receipt of the
gross proceeds of the offering.  The
terms of the Warrants are governed by a Warrant Agreement, dated as of           ,
2007, between the Company and Continental Stock Transfer & Trust Company,
as Warrant Agent, and are subject to the terms and provisions contained therein,
all of which terms and provisions the holder of this certificate consents to by
acceptance hereof.  Copies of the Warrant
Agreement are on file at the office of the Warrant Agent at 17 Battery Place,

available to any Warrant holder on written request and without cost. This
certificate is not valid unless countersigned by the Transfer Agent and
Registrar of the Company.

WARRANT

THIS CERTIFIES THAT, for
value received

is the registered
holder of a Warrant or Warrants expiring                ,
2011 (the “Warrant”) to purchase one fully paid and non-assessable share of
Common Stock, par value $.0001 per share (the “Shares”), of ARCADE ACQUISITION
CORP., a Delaware corporation (the “Company”), for each Warrant evidenced by
this Warrant Certificate.  The Warrant
entitles the holder thereof to purchase from the Company, commencing on the
later of (i) the Company’s completion of a business combination with a target
business or (ii)                      ,
2008, such number of Shares of the Company at the price of $6.00 per share,
upon surrender of this Warrant Certificate and payment of the Warrant Price at
the office or agency of the Warrant Agent, Continental Stock Transfer &
Trust Company (such payment to be made by check made payable to the Warrant
Agent), but only subject to the conditions set forth herein and in the Warrant
Agreement between the Company and Continental Stock Transfer & Trust
Company.  The Warrant Agreement provides
that upon the occurrence of certain events the Warrant Price and the number of
Warrant Shares purchasable hereunder, set forth on the face hereof, may,
subject to certain conditions, be adjusted. 
The term Warrant Price as used in this Warrant Certificate refers to the
price per Share at which Shares may be purchased at the time the Warrant is
exercised.

No fraction of a Share
will be issued upon any exercise of a Warrant.  If, upon exercise of a Warrant, a holder would be entitled to receive a
fractional interest in a Share, the Company will, upon exercise, round up to
the nearest whole number the number of shares of common stock to be issued to
the warrant holder.

Upon any exercise of the
Warrant for less than the total number of full Shares provided for herein,
there shall be issued to the registered holder hereof or his assignee a new
Warrant Certificate covering the number of Shares for which the Warrant has not
been exercised.

Warrant Certificates,
when surrendered at the office or agency of the Warrant Agent by the registered
holder hereof in person or by attorney duly authorized in writing, may be
exchanged in the manner and subject to the limitations provided in the Warrant
Agreement, but without payment of any service charge, for another Warrant
Certificate or Warrant Certificates of like tenor and evidencing in the
aggregate a like number of Warrants.

Upon due presentment for
registration of transfer of the Warrant Certificate at the office or agency of
the Warrant Agent, a new Warrant Certificate or Warrant Certificates of like
tenor and

 1
 

evidencing in the
aggregate a like number of Warrants shall be issued to the transferee in
exchange for this Warrant Certificate, subject to the limitations provided in
the Warrant Agreement, without charge except for any applicable tax or other
governmental charge.

The Company and the
Warrant Agent may deem and treat the registered holder as the absolute owner of
this Warrant Certificate (notwithstanding any notation of ownership or other
writing hereon made by anyone), for the purpose of any exercise hereof, of any
distribution to the registered holder, and for all other purposes, and neither
the Company nor the Warrant Agent shall be affected by any notice to the
contrary.

This Warrant does not
entitle the registered holder to any of the rights of a stockholder of the
Company.

The Company reserves the
right to call the Warrant at any time prior to its exercise, with a notice of
call in writing to the holders of record of the Warrant, giving 30 days’ notice
of such call at any time after the Warrant becomes exercisable if the last sale
price of the Shares equals or exceeds $11.50 per share on each of 20 trading
days within a 30 trading day period ending on the third business day prior to
the date on which notice of such call is given. The call price of the Warrants
is to be $.01 per Warrant. Any Warrant either not exercised or tendered back to
the Company by the end of the date specified in the notice of call shall be
canceled on the books of the Company and have no further value except for the
$.01 call price.
