                                THE MERGER

merged with and into the Bank (the "Merger") under the charter of the Bank, and
the Bank shall be the surviving corporation (sometimes hereinafter referred to
as the "Corporation" when reference is made to it after the Effective Time of 
the Merger (as defined below)). The name of the surviving corporation shall be

hereto.

               (b)  The Merger shall occur immediately following the

such other date and time as Brent and the Bank may mutually designate.

          1.2  Effect of Merger.  At the Effective Time of the Merger, Brent
shall be merged with and into the Bank and the separate existence of Brent shall
cease.  All of the shares of capital stock of Brent issued and outstanding as of
the Effective Time of the Merger, and all rights in respect thereof, shall be
canceled.  The shares of capital stock of the Bank outstanding immediately prior
to consummation of the Merger shall constitute the only outstanding shares of
capital stock of the Corporation following consummation of the Merger.  

          1.3  Conveyance.  All assets of the Bank and Brent as they exist at
the Effective Time of the Merger shall pass to and vest in the Corporation
without any conveyance or other transfer.  The Corporation shall be responsible
for all the liabilities of every kind and description of each of Brent and the
Bank existing as of the Effective Time of the Merger.

          1.4  Board of Directors; Articles of Incorporation; Bylaws.  The
present Board of Directors of the Bank shall continue to serve as the Board of
Directors of the Corporation until the next annual meeting or until such time as
their successors have been elected and have qualified.  The number, names and
residence addresses, and the terms of the members of the Board of Directors, are
set forth in Annex B hereto.  Effective as of the time this Merger shall become
effective, the Articles of Incorporation and the Bylaws of the Corporation shall

                                ARTICLE II

                              CAPITALIZATION

          2.1  Capitalization of the Bank.  As of the date hereof, the
authorized capital stock of the Bank consists of 25,000 shares of common stock,

which is held in the treasury of the Bank.

          2.2. Capitalization of Brent.  As of the date hereof, the authorized
capital stock of Brent consists of 4,000 shares of common stock, par value
$100.00 per share, 4,000 shares of which are issued and outstanding and none of
which is held in the treasury of Brent.      


                                ARTICLE III

                                 COVENANTS

          3.1  Covenants of the Bank and Brent.  During the period from the
date of this Agreement and continuing until the Effective Time of the Merger,
each of the parties hereto agrees to observe and perform all agreements and
covenants in the Share Exchange Agreement that pertain or are applicable to the
Bank and Brent, respectively.  Each of the parties hereto agrees to use all
reasonable efforts to take, or cause to be taken, all action and to do, or cause
to be done, all things necessary, proper or advisable under applicable laws and
regulations to consummate and make effective the transactions contemplated by
this Agreement, subject to and in accordance with the applicable provisions of
the Share Exchange Agreement.

          3.2  Certain Indemnification of Brent.  USB and Brent have agreed
in the Share Exchange Agreement that USB and Bank have no obligation to
indemnify, defend or hold harmless Brent or any of its officers, directors,
employees or agents against any losses, expenses, claims, damages or liabilities
of any nature whatsoever. In order to consummate the Merger contemplated by this
Agreement immediately after the Share Exchange contemplated by the Share 
Exchange Agreement, USB has requested Brent to execute this Agreement, and 
Brent has determined to execute this Agreement, provided that USB provide the
indemnification described in this paragraph.  USB and Bank shall indemnify,
defend and hold harmless Brent, and its officers, directors, employees and 
agents (collectively, the "Indemnitees") from and against any and all claims, 
demands, actions, or causes of action, that are asserted against any Indemnitee 
by any person if the claim, demand, action, or cause of action: (i) is caused 
directly and solely by the execution of this Agreement by Brent (and not in any 
way related to, arising out of, or caused by the Share Exchange Agreement or the
transactions contemplated thereby);  and (ii) arises during the period between
the date of execution of this Agreement and the Effective Time of the Merger.

sole shareholder of the Bank each shall have voted affirmatively to approve the
