Stock and other securities of the Company and its subsidiaries beneficially
owned by them, upon request of the Company from time to time following the

price prevailing on the date of sale. The Company and, if the Company is unable
or unwilling to make such purchase, the then current members of the Board of
Directors, shall have a right of first refusal on such shares to buy some or all
of them at the price and terms stated in the notice, which may be exercised no
later than seven days from the date of notice. If not all of such shares are so
purchased by the Company or the members of the Board of Directors, the Investor
may sell them to the third party (subject to the limitations in 2(a) above) at
the price and terms stated in the notice, at any time within the 30 days
following the failure of the Company or the Board of Directors to exercise its
option.

above, for so long as the Investors beneficially own any Common Stock, the
Investors will (a) be present, in person or represented by proxy, at all

by the Investors may be counted for the purpose of determining the presence of a
quorum at such meetings and (b) with respect to the election of directors, vote
or consent, or cause to be voted or a consent to be given, with respect to all
Common Stock beneficially owned by the Investors on all matters submitted to

and representatives not to, challenge the validity of any provisions of this
Agreement. In the event that any part of this Agreement or any transaction
contemplated hereby is temporarily, preliminarily or permanently enjoined or
restrained by a court of competent jurisdiction, the parties hereto shall use
their reasonable best efforts to cause any such injunction or restraining order
to be vacated or dissolved or otherwise declared or determined to be of no
further force or effect. During the term of this Agreement, each of the
Investors agrees not to make any public statement or comment or private
statement or comment which could reasonably be expected to become public which
could in any way be deemed to diminish the reputation of or otherwise disparage

in no way (i) estop either party from making factual statements which are
reasonably necessary or appropriate in the ordinary course of its business or
(ii) limit the ability of any party to pursue any remedy under this Agreement or

     5. CONFIDENTIALITY AGREEMENT. The Company, the Bank and the Investors shall
enter into the Confidentiality Agreement attached hereto as Annex A. It is
understood and agreed that a material inducement to the Company to enter into
this Agreement is the agreement of the Investors to enter into and perform the
terms of the Confidentiality Agreement. Accordingly, failure of any Investor to
comply with the provisions of such agreements shall constitute cause for the
Company to terminate this Agreement.
