WARRANT 

        THIS
CERTIFIES THAT, for value received                        is the registered holder of a Warrant or Warrants
expiring            , 2008 (the "Warrant") to purchase one fully paid and
non-assessable share of Common Stock, par value $.01 per share ("Shares"), of Coastal Bancshares 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 consummation by the Company of a merger, capital stock
exchange, asset acquisition or other similar business combination or (ii)                         , 2004, such number of
Shares of the Company at the price of $5.00 per share, upon surrender of this
Warrant Certificate and payment of the Warrant Price at the office or agency of the Warrant Agent, American 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 American 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 the holder of a Warrant would be entitled to receive a fraction of a Share upon any exercise of a Warrant, the
Company shall, upon such exercise, round up to the nearest whole number the number of Shares to be issued to such 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 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 until exercised. 

        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 Warrantholders of Record, giving 30 days' notice of
such call at any time after the Warrant becomes exercisable if the last sale price of the Shares has been at least $8.50 per share on each of 20 trading days within any 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.
