     ----------  --------------------------------

     (a) Stock Option Agreement. Each grant of an Option under the Plan shall be

evidenced by a Stock Option Agreement between the Optionee and the Bank. Such

the Plan and which the Committee deems appropriate for inclusion in a Stock
Option Agreement. Subject to Section 4(b), the provisions of the various Stock
Option Agreements entered into under the Plan need not be identical.

     (b) Number of Shares. Each Stock Option Agreement shall specify the number

         -----------------
Optionee shall make such arrangements as the Committee may require for the
satisfaction of any federal, state or local withholding tax obligations that may
arise in connection with such exercise. The Optionee shall also make such
arrangements as the Committee may require for the satisfaction of any federal,
state or local withholding tax obligations that may arise in connection with the
disposition of Shares acquired by exercising an Option. An Optionee may satisfy
all or part of the Optionee's withholding or income tax obligations by having
the Bank withhold all or a portion of any Shares that otherwise would be issued
to the Optionee or by surrendering all or a portion of any Shares that the
Optionee previously acquired. Such Shares shall be valued at their Fair Market
Value on the date when taxes otherwise would be withheld in cash. Any payment of
taxes by assigning Shares to the Bank may be subject to restrictions imposed by
the Committee.

     (e) Nontransferability. During an Optionee's lifetime, the Optionee's
         ------------------
Option(s) shall be exercisable only by the Optionee and shall not be
transferable. In the event of an Optionee's death, the Optionee's Option(s)
shall not be transferable other than by will, beneficiary designation or by the
laws of descent and distribution.

     (f) Exercise of Options Upon Termination of Service. Each Stock Option
         -----------------------------------------------
Agreement shall set forth the extent to which the Optionee shall have the right
to exercise the Option following termination of the Optionee's Service with the
Bank and its Subsidiaries as set forth in Section 4(b)(iii), and may specify the
right to exercise the Option of any executors or administrators of the
Optionee's estate or any person who has acquired such Option(s) directly from
the Optionee by beneficiary designation, bequest or inheritance.

     (g) No Rights as a Stockholder. An Optionee, or a transferee of an
         --------------------------
Optionee, shall have no rights as a stockholder with respect to any Shares
covered by the Optionee's Option until the date of the issuance of a stock
certificate for such Shares. No adjustments shall be made, except as provided in
Section 8.

     (h) Restrictions on Transfer of Shares. Any Shares issued upon exercise of
         -----------------------------------
an Option shall be subject to such special forfeiture conditions, rights of
repurchase, rights of first refusal

                                      -6-



and other transfer restrictions as the Committee may determine. Such
restrictions shall be set forth in the applicable Stock Option Agreement and
shall apply in addition to any general restrictions that may apply to all
holders of Shares.

     SECTION 7.  PAYMENT FOR SHARES.
     ----------  -------------------

     The entire Exercise Price shall be payable in lawful money of the United
States of America at the time when Options are exercised.

     SECTION 8.  ADJUSTMENT OF SHARES.
     ----------  ---------------------

     (a) General. In the event of a subdivision of the outstanding Stock, a
         -------
declaration of a dividend payable in Shares, a declaration of a dividend payable
in a form other than Shares in an amount that has a material effect on the value
of Shares, a combination or consolidation of the outstanding Stock (by
reclassification or otherwise) into a lesser number of Shares, a
recapitalization or a similar occurrence, the Committee shall make appropriate
adjustments in one or more of (i) the number of Shares available for future
grants under Section 5, (ii) the number of Shares covered by each outstanding
Option or (iii) the Exercise Price under each outstanding Option.

     (b) Reorganizations. In the event that the Bank is a party to a merger or
         ---------------
other reorganization, outstanding Options shall be subject to the agreement of
merger or reorganization. Such agreement may provide for the assumption of
outstanding Options by the surviving corporation or its parent or for their
continuation by the Bank (if the Bank is a surviving corporation); provided,
however, that if assumption or continuation of the outstanding Options is not
provided by such agreement then the Committee shall have the option of offering
the payment of a cash settlement equal to the difference between the amount to
be paid for one Share under such agreement and the Exercise Price, in all cases
without the Optionees' consent.

     (c) Reservation of Rights. Except as provided in this Section 8, an
         ---------------------
Optionee shall have no rights by reason of any subdivision or consolidation of
shares of stock of any class, the payment of any dividend or any other increase
or decrease in the number of shares of stock of any class. Any issue by the Bank
of shares of stock of any class, or securities convertible into shares of stock
of any class, shall not affect, and no adjustment by reason thereof shall be
made with respect to, the number or Exercise Price of Shares subject to an
Option. The grant of an Option pursuant to the Plan shall not affect in any way
the right or power of the Bank to make adjustments, reclassifications,
reorganizations or changes of its capital or business structure, to merge or
consolidate or to dissolve, liquidate, sell or transfer all or any part of its
business or assets.

     SECTION 9.  LEGAL AND REGULATORY REQUIREMENTS.
     ---------   ----------------------------------

     Shares shall not be issued under the Plan unless the issuance and delivery
of such Shares complies with (or is exempt from) all applicable requirements of
law, including (without limitation) the Securities Act of 1933, as amended, the
rules and regulations promulgated thereunder, state securities laws and
regulations and the regulations of any stock exchange on which the Bank's
securities may then be listed, and the Bank has obtained the approval or

                                      -7-



favorable ruling from any governmental agency which the Bank determines is
necessary or advisable.

amendment to Sections 4 or 5 of the Plan shall be subject to the approval of the
Bank's shareholders. Rights and obligations under any Option granted before
amendment of the Plan shall not be materially altered, or impaired adversely, by
such amendment, except with consent of the person to whom the Option was
granted. Except as otherwise provided in this Section 10(b), an amendment of the
Plan shall be subject to the approval of the Bank's stockholders only to the
extent required by applicable laws, regulations or rules.

     (c) Effect of Amendment or Termination. No Shares shall be issued or sold
         ----------------------------------
under the Plan after the termination thereof, except upon exercise of an Option
granted prior to such termination. The termination of the Plan, or any amendment
thereof, shall not affect any Share previously issued or any Option previously
granted under the Plan.
