as described in the Company's Registration Statement, and in accordance with the Company's Certificate of Incorporation,
$                        of the gross proceeds of the IPO

deposited and held in a trust account for the benefit of the
Company and the holders of the Company's common stock, par value $.01 per share, issued in the IPO and in the event the Units are registered in Colorado, pursuant to

        WHEREAS,
the Company and the Trustee desire to enter into this Agreement to set forth the terms and conditions pursuant to which the Trustee shall hold the Property; 

        IT
IS AGREED: 

        1.     Agreements
and Covenants of Trustee. The Trustee hereby agrees and covenants to: 

        (a)   Hold
the Property in trust for the Beneficiaries in accordance with the terms of this Agreement, including the terms of
Section 11-51-302(6) of the Colorado Statute in a segregated trust account ("Trust Account") established by the Trustee at a branch of JPMorgan Chase NY Bank selected by
the Trustee; 

        (b)   Manage,
supervise and administer the Trust Account subject to the terms and conditions set forth herein; 

        (c)   In
a timely manner, upon the instruction of the Company, to invest and reinvest the Property in any "Government Security." As used herein, Government Security means any
Treasury Bill issued by the United States, having a maturity of one hundred and eighty days or less; 

        (d)   Collect
and receive, when due, all principal and income arising from the Property, which shall become part of the "Property," as such term is used herein; 

        (e)   Notify
the Company of all communications received by it with respect to any Property requiring action by the Company; 

        (f)    Supply
any necessary information or documents as may be requested by the Company in connection with the Company's preparation of the tax returns for the Trust Account; 

        (g)   Participate
in any plan or proceeding for protecting or enforcing any right or interest arising from the Property if, as and when instructed by the Company to do so; 

        (h)   Render
to the Company and to the Representatives, and to such other person as the Company may instruct, monthly written statements of the activities of and amounts in
the Trust Account reflecting all receipts and disbursements of the Trust Account; and 

1

 

        (i)    Commence
liquidation of the Trust Account only after receipt of and only in accordance with the terms of a letter ("Termination Letter"), in a form substantially similar
to that attached hereto as either Exhibit A or Exhibit B, signed on behalf of the Company by its President or Chairman of the Board and Secretary, and complete the liquidation of the
Trust Account and distribute the Property in the Trust Account only as directed in the Termination Letter and the other documents referred to therein. 

        2.     Agreements
and Covenants of the Company. The Company hereby agrees and covenants to: 

        (a)   Give
all instructions to the Trustee hereunder in writing, signed by the Company's President or Chairman of the Board. In addition, except with respect to its duties
under paragraph 1(i) above, the Trustee shall be entitled to rely on, and shall be protected in relying on, any verbal or telephonic advice or instruction which it in good faith believes
to be given by any one of the persons authorized above to give written instructions, provided that the Company shall promptly confirm such instructions in writing; 

        (b)   Hold
the Trustee harmless and indemnify the Trustee from and against, any and all expenses, including reasonable counsel fees and disbursements, or loss suffered by the
Trustee in connection with any action, suit or other proceeding brought against the Trustee involving any claim, or in connection with any claim or demand which in any way arises out of or relates to
this Agreement, the services of the Trustee hereunder, or the Property or any income earned from investment of the Property, except for expenses and losses resulting from the Trustee's gross
negligence or willful misconduct. Promptly after the receipt by the Trustee of notice of demand or claim or the commencement of any action, suit or proceeding, pursuant to which the Trustee intends to
seek indemnification under this paragraph, it shall notify the Company in writing of such claim (hereinafter referred to as the "Indemnified Claim"). The Trustee shall have the right to conduct and
manage the defense against such Indemnified Claim, provided, that the Trustee shall obtain the consent of the Company with respect to the selection of counsel, which consent shall not be unreasonably
withheld. The Company may participate in such action with its own counsel; and 

        (c)   Pay
the Trustee an initial acceptance fee of $1,000 and an annual fee of $3,000 (it being expressly understood that the Property shall not be used to pay such fee). The
Company shall pay the Trustee the initial acceptance fee and first year's fee at the consummation of the IPO and thereafter on the anniversary of the Effective Date. The Trustee shall refund to the
Company the fee (on a pro rata basis) with respect to any period after the liquidation of the Trust Fund. The Trustee shall also be entitled to reimbursement from the Company for all expenses paid or
incurred by it in the
administration of its duties hereunder including, but not limited to, all counsel, advisors' and agents' fees and disbursements and all taxes or other governmental charges. The Company shall not be
responsible for any other fees or charges of the Trustee except as set forth in this Section 2(c) and as may be provided in paragraph 2(b) hereof (it being expressly understood that the
Property shall not be used to make any payments to the Trustee under such paragraph). 

        3.     Limitations
of Liability. The Trustee shall have no responsibility or liability to: 

        (a)   Take
any action with respect to the Property, other than as directed in paragraph 1 hereof and the Trustee shall have no liability to any party except for
liability arising out of its own gross negligence or willful misconduct; 

        (b)   Institute
any proceeding for the collection of any principal and income arising from, or institute, appear in or defend any proceeding of any kind with respect to, any
of the Property unless and until it shall have received instructions from the Company given as provided herein to 

2

 

do
so and the Company shall have advanced or guaranteed to it funds sufficient to pay any expenses incident thereto; 

        (c)   Change
the investment of any Property, other than in compliance with paragraph 1(c); 

        (d)   Refund
any depreciation in principal of any Property; 

        (e)   Assume
that the authority of any person designated by the Company to give instructions hereunder shall not be continuing unless provided otherwise in such designation,
or unless the Company shall have delivered a written revocation of such authority to the Trustee; 

        (f)    The
other parties hereto or to anyone else for any action taken or omitted by it, or any action suffered by it to be taken or omitted, in good faith and in the exercise
of its own best judgment, except for its gross negligence or willful misconduct. The Trustee may rely conclusively and shall be protected in acting upon any order, notice, demand, certificate, opinion
or advice of counsel (including counsel chosen by the Trustee), statement, instrument, report or other paper or document (not only as to its due execution and the validity and effectiveness of its
provisions, but also as to the truth and acceptability of any information therein contained) which is believed by the Trustee, in good faith, to be genuine and to be signed or presented by the proper
person or persons. The Trustee shall not be bound by any notice or demand, or any waiver, modification, termination or rescission of this
agreement or any of the terms hereof, unless evidenced by a written instrument delivered to the Trustee signed by the proper party or parties and, if the duties or rights of the Trustee are affected,
unless it shall give its prior written consent thereto; 

        (g)   Verify
the correctness of the information set forth in the Registration Statement or to confirm or assure that any acquisition made by the Company or any other action
taken by it is as contemplated by the Registration Statement; and 

        (h)   Pay
any taxes on behalf of the Trust Account (it being expressly understood that the Property shall not be used to pay any such taxes and that such taxes, if any, shall
be paid by the Company from funds not held in the Trust Account). 

        4.     Termination.
This Agreement shall terminate as follows: 

        (a)   If
the Trustee gives written notice to the Company that it desires to resign under this Agreement, the Company shall use its reasonable efforts to locate a successor
trustee. At such time that the Company notifies the Trustee that a successor trustee has been appointed by the Company and has agreed to become subject to the terms of this Agreement, the Trustee
shall transfer the management of the Trust Account to the successor trustee, including but not limited to the transfer of copies of the reports and statements relating to the Trust Account, whereupon
this Agreement shall terminate; provided, however, that, in the event that the Company does not locate a successor trustee within ninety days of receipt of the resignation notice from the Trustee, the
Trustee may submit an application to have the Property deposited with the United States District Court for the Southern District of New York and upon such deposit, the Trustee shall be immune from any
liability whatsoever; 

        (b)   At
such time that the Trustee has completed the liquidation of the Trust Account in accordance with the provisions of paragraph 1(i) hereof, and
distributed the Property in accordance with the provisions of the Termination Letter, this Agreement shall terminate except with respect to Paragraph 2(b); or 

        (c)   On
such date after                        , 2006 when the Trustee deposits the Property with the United States District Court for the
Southern District of New York in the event
that, prior to such date, the Trustee has not received a Termination Letter from the Company pursuant to paragraph 1(i). 

3

 

        5.     Miscellaneous.

        (a)   The
Company and the Trustee each acknowledge that the Trustee will follow the security procedures set forth below with respect to funds transferred from the Trust
Account. Upon receipt of written instructions, the Trustee will confirm such instructions with an Authorized Individual at an Authorized Telephone Number listed on the attached Exhibit C. The
Company and the Trustee will each restrict access to confidential information relating to such security procedures to authorized persons. Each party must notify the other party immediately if it has
reason to believe unauthorized persons may have obtained access to such information, or of any change in its authorized personnel. In executing funds transfers, the Trustee will rely upon account
numbers or other identifying numbers of a beneficiary, beneficiary's bank or intermediary bank, rather than names. The Trustee shall not be liable for any loss, liability or expense resulting from any
error in an account number or other identifying number, provided it has accurately transmitted the numbers provided. 

        (b)   This
Agreement shall be governed by and construed and enforced in accordance with the laws of the State of New York, without giving effect to conflict of laws. It may be
executed in several counterparts, each one of which shall constitute an original, and together shall constitute but one instrument. 

        (c)   This
Agreement contains the entire agreement and understanding of the parties hereto with respect to the subject matter hereof. This Agreement or any provision hereof
may only be changed, amended or modified by a writing signed by each of the parties hereto; provided, however, that no such change, amendment or modification may be made without the prior written
consent of the Representative. As to any claim, cross-claim or counterclaim in any way relating to this Agreement, each party waives the right to trial by jury. 

        (d)   The
parties hereto consent to the jurisdiction and venue of any state or federal court located in the City of New York for purposes of resolving any disputes hereunder. 

        (e)   Any
notice, consent or request to be given in connection with any of the terms or provisions of this Agreement shall be in writing and shall be sent by express mail or
similar private courier service, by certified mail (return receipt requested), by hand delivery or by facsimile transmission:

STOCK ESCROW AGREEMENT  

        STOCK ESCROW AGREEMENT, dated as of                        , 2004
("Agreement"), by and among COASTAL BANCSHARES ACQUISITION CORP., a Delaware corporation ("Company"),
CARY M. GROSSMAN, COASTAL ACQUISITION, LLC, W. DONALD BRUNSON, SCOTT CLINGAN, FRED S. ZEIDMAN, JEFFREY P. SANGALIS (collectively "Initial Stockholders") and AMERICAN STOCK TRANSFER & TRUST
COMPANY, a New York corporation ("Escrow Agent"). 

        WHEREAS,
the Company has entered into an Underwriting Agreement, dated            , 2004 ("Underwriting Agreement"), with Newbridge Securities Corporation and I-Bankers
Securities Incorporated (collectively, the "Representatives") acting as representative of the several underwriters (collectively, the "Underwriters"), pursuant to which, among other matters, the
Underwriters will agree to purchase 4,000,000 units ("Units") of the Company. Each Unit will consist of one share of the Company's Common Stock, par value $.01 per share, and two Warrants, each
Warrant to purchase one share of Common Stock, all as more fully described in the Company's final Prospectus, dated            , 2004 ("Prospectus") comprising part of the Company's
Registration
Statement on Form S-1 (File No. 333-118294) under the Securities Act of 1933, as amended ("Registration Statement"), declared effective
on                        , 2004
("Effective Date"). 

        WHEREAS,
the Initial Stockholders have agreed as a condition of the sale of the Units to deposit their shares of Common Stock of the Company, as set forth opposite their respective names
in Exhibit A attached hereto (collectively "Escrow Shares"), in escrow as hereinafter provided. 

        WHEREAS,
the Company and the Initial Stockholders desire that the Escrow Agent accept the Escrow Shares, in escrow, to be held and disbursed as hereinafter provided. 

        IT
IS AGREED: 

        1.     Appointment
of Escrow Agent. The Company and the Initial Stockholders hereby appoint the Escrow Agent to act in accordance with and subject to the terms of this Agreement
and the Escrow Agent hereby accepts such appointment and agrees to act in accordance with and subject to such terms. 

        2.     Deposit
of Escrow Shares. On or before the Effective Date, each of the Initial Stockholders shall deliver to the Escrow Agent certificates representing his respective
Escrow Shares, to be held and disbursed subject to the terms and conditions of this Agreement. Each Initial Stockholder acknowledges that the certificate representing his Escrow Shares is legended to
reflect the deposit of such Escrow Shares under this Agreement. 

        3.     Disbursement
of the Escrow Shares. The Escrow Agent shall hold the Escrow Shares until the third anniversary of the Effective Date ("Escrow Period"), on which date it
shall, upon written instructions from each Initial Stockholder, disburse each of the Initial Stockholder's Escrow Shares to such Initial Stockholder; provided, however, that if the Escrow Agent is
notified by the Company pursuant to Section 6.7 hereof that the Company is being liquidated at any time during the Escrow Period, then the Escrow Agent shall promptly destroy the certificates
representing the Escrow Shares and; provided further, that if, after the Company consummates a Business Combination (as such term is defined in the Registration Statement), it (or the surviving
entity) subsequently consummates a liquidation, merger, stock exchange or other similar transaction which results in all of the stockholders of such entity having the right to exchange their shares of
Common Stock for cash, securities or other property, then the Escrow Agent will, upon receipt of a certificate, executed by the Chief Executive Officer or Chief Financial Officer of the Company, in
form reasonably acceptable to the Escrow Agent, that such transaction is then being consummated, release the Escrow Shares to the Initial Stockholders upon consummation of the transaction so that they
can similarly participate. The Escrow Agent shall 

1

 

have
no further duties hereunder after the disbursement or destruction of the Escrow Shares in accordance with this Section 3. 

        4.     Rights
of Initial Stockholders in Escrow Shares. 

        4.1    Voting Rights as a Stockholder.    Subject to the terms of the Insider Letter described in Section 4.4
hereof and except as herein provided, the Initial Stockholders shall retain all of their rights as stockholders of the Company during the Escrow Period, including, without limitation, the right to
vote such shares. 

        4.2    Dividends and Other Distributions in Respect of the Escrow Shares.    During the Escrow Period, all dividends
payable in cash with respect to the Escrow Shares shall be paid to the Initial Stockholders, but all dividends payable in stock or other non-cash property ("Non-Cash
Dividends") shall be delivered to the Escrow Agent to hold in accordance with the terms hereof. As used herein, the term "Escrow Shares" shall be deemed to include the Non-Cash Dividends
distributed thereon, if any. 

        4.3    Restrictions on Transfer.    During the Escrow Period, no sale, transfer or other disposition may be made of
any or all of the Escrow Shares except (i) by gift to a member of Initial Stockholder's immediate family or to a trust, the beneficiary of which is an Initial Stockholder or a member of an
Initial Stockholder's immediate family, (ii) by virtue of the laws of descent and distribution upon death of any Initial Stockholder, (iii) pursuant to a qualified domestic relations
order, or (iv) pursuant to a transfer of record ownership whereby there is no change in beneficial ownership; provided, however, that such permissive transfers may be implemented only upon the
respective transferee's written agreement to be bound by the terms and conditions of this Agreement and of the Insider Letter signed by the Initial Stockholder transferring the Escrow Shares. During
the Escrow Period, the Initial Stockholders shall not pledge or grant a security interest in the Escrow Shares or grant a security interest in their rights under this Agreement. 

        4.4    Insider Letters.    Each of the Initial Stockholders has executed a letter agreement with the Representatives
and the Company, dated as indicated on Exhibit A hereto, and which is filed as an exhibit to the Registration Statement ("Insider Letter"), respecting the rights and obligations of such Initial
Stockholder in certain events, including but not limited to the liquidation of the Company. 

        5.     Concerning
the Escrow Agent. 

        5.1    Good Faith Reliance.    The Escrow Agent shall not be liable for any action taken or omitted by it in good
faith and in the exercise of its own best judgment, and may rely conclusively and shall be protected in acting upon any order, notice, demand, certificate, opinion or advice of counsel (including
counsel chosen by the Escrow Agent), statement, instrument, report or other paper or document (not only as to its due execution and the validity and effectiveness of its provisions, but also as to the
truth and acceptability of any information therein contained) which is believed by the Escrow Agent to be genuine and to be signed or presented by the proper person or persons. The Escrow Agent shall
not be bound by any notice or demand, or any waiver, modification, termination or rescission of this Agreement unless evidenced by a writing delivered to the Escrow Agent signed by the proper party or
parties and, if the duties or rights of the Escrow Agent are affected, unless it shall have given its prior written consent thereto. 

        5.2    Indemnification.    The Escrow Agent shall be indemnified and held harmless by the Company from and against any
expenses, including counsel fees and disbursements, or loss suffered by the Escrow Agent in connection with any action, suit or other proceeding involving any claim which in any way, directly or
indirectly, arises out of or relates to this Agreement, the services of the Escrow Agent hereunder, or the Escrow Shares held by it hereunder, other than expenses or losses arising from the gross
negligence or willful misconduct of the Escrow Agent. 

2

 

Promptly
after the receipt by the Escrow Agent of notice of any demand or claim or the commencement of any action, suit or proceeding, the Escrow Agent shall notify the other parties hereto in
writing. In the event of the receipt of such notice, the Escrow Agent, in its sole discretion, may commence an action in the nature of interpleader in an appropriate court to determine ownership or
disposition of the Escrow Shares or it may deposit the Escrow Shares with the clerk of any appropriate court or it may retain the Escrow Shares pending receipt of a final, non-appealable
order of a court having jurisdiction over all of the parties hereto directing to whom and under what circumstances the Escrow Shares are to be disbursed and delivered. The provisions of this
Section 5.2 shall survive in the event the Escrow Agent resigns or is discharged pursuant to Sections 5.5 or 5.6 below. 

        5.3    Compensation.    The Escrow Agent shall be entitled to reasonable compensation from the Company for all
