                       NONSTATUTORY STOCK OPTION AGREEMENT
                         Annual Vesting Over Four Years


Nonstatutory Stock Option     This Option is not intended to be an incentive
                              stock option under Section 422 of
                              the Code and will be interpreted accordingly.

Vesting and Exercise          This Option may be exercised to the extent that
                              Shares have been vested. Beginning on the Vesting
                              Start Date, you will be twenty percent (20%)
                              vested in the Shares granted under this Option.
                              Thereafter, the Shares under this Option will
                              vest annually at a rate of 20 percent (20%) per
                              year.  All of the Shares shall be fully vested on
                              the fourth anniversary of the Vesting Start Date
                              as shown on the cover sheet.  No additional
                              Shares will vest after your Service has terminated
                              for any reason.  "Service" means your service as
                              an outside director of the Bank or an affiliated
                              entity.

                              "Shares" means the shares of Common Stock covered
                              by this Option as adjusted pursuant to Section 8
                              of the Plan.

                              Notwithstanding the vesting schedule set forth
                              above, in the event of a Change in Control during
                              the period you remain in Service, all of the
                              Shares which are unvested as of the effective
                              date of such Change in Control shall immediately
                              become vested. For the purposes hereof, "Change
                              in Control" shall have the meaning set forth in
                              Section 2(c) of the Plan.

Term                          This Option will expire in any event at the close
                              of business at Bank headquarters on the fifth
                              anniversary of the Date of Grant, as shown on the
                              cover sheet. (It will expire earlier if your
                              Service terminates, as described below.)

Regular Termination           If your Service terminates for any reason except
                              death or Total and Permanent Disability, then
                              this Option will expire at the close of business
                              at Bank headquarters on the 90th day after your
                              termination date. During that 90-day period, you
                              may exercise the vested portion of this Option.

Other Terminations            If your Service terminates following your
of Service                    conviction of a felony, or a finding by a court
                              that you engaged in a fraudulent or dishonest act
                              or a gross abuse of authority regarding the Bank
                              then this Option will expire upon your termination
                              of Service.

                                      -2-



Death                         In the event of your death while in Service, then
                              this Option will expire at the close of business
                              at Bank headquarters on the date which is one
                              year after the date of death. During that one-year
                              period, your estate or heirs may exercise the
                              vested portion of this Option as of the
                              termination of Service.

Total and                     If your Service terminates because of your
Permanent                     Total and Permanent Disability, then this Option
Disability                    will expire at the close of business at Bank
                              headquarters on the date which is one year after
                              your termination date. During that one-year
                              period, you may exercise the vested portion of
                              this Option as of the termination of Service.

                              "Total and Permanent Disability" means that you
                              are unable to serve on the Board of Directors due
                              to a disability which shall be determined in
                              accordance with the Bank's Long Term Disability
                              Plan.

Restrictions on               The Bank will not permit you to exercise  this
Exercise                      Option if the issuance of Shares at that time
                              would violate any law or regulation.

Notice of Exercise            When you wish to exercise this Option, you must
                              notify the Bank by filing the proper "Notice of
                              Exercise" form attached hereto. Your notice must
                              specify how many Shares you wish to purchase. Your
                              notice must also specify how your Shares should
                              be registered (in your name only or in your and
                              your spouse's names as community property or as
                              joint tenants with right of survivorship). The
                              notice will be effective when it is received by
                              the Bank.

                              If someone else wants to exercise this Option
                              after your death, that person must prove to the
                              Bank's satisfaction that he or she is entitled to
                              do so.

Periods of                    Any other provision of this Agreement
Nonexercisability             notwithstanding, the Bank shall have the right to
                              designate one or more periods of time, each of
                              which shall not exceed 180 days in length, during
                              which this Option shall not be exercisable if the
                              Bank determines (in its sole discretion)
                              that such limitation on exercise could in any way
                              facilitate any offering and/or issuance of
                              securities by the Bank, facilitate the
                              registration or qualification of any securities
                              by the Bank under the applicable laws, or
                              facilitate the perfection of any exemption from
                              the registration or qualification requirements
                              of any applicable securities laws for the issuance
                              or transfer of any securities. Such limitation on
                              exercise shall not alter the vesting schedule set
                              forth in this Agreement other than to limit the
                              periods during which this Option shall be
                              exercisable.

Withholding Taxes             You will not be allowed to exercise this Option
                              unless you make acceptable arrangements to pay
                              any withholding or other taxes that may be due
                              as a result of the Option exercise.

Restrictions on               By signing this Agreement, you agree not to sell

                              policies prohibit a sale. In connection with any
                              underwritten public offering by the Bank of its
                              equity securities, you agree not to sell, make any

                              of time after the effective date of such
                              registration statement as may be requested by the
                              Bank or such underwriters.

                              In order to enforce the provisions of this
                              paragraph, the Bank may impose stop-transfer
                              instructions with respect to the Shares until the

                              For instance, you may not sell this Option or use
                              it as security for a loan. If you attempt to do
                              any of these things, this Option will immediately
                              become invalid. You may, however, dispose of this
                              Option in your will.

                              Regardless of any marital property settlement
                              agreement, the Bank is not obligated to honor a
                              notice of exercise from your spouse or former
                              spouse, nor is the Bank obligated to recognize
                              such individual's interest in this Option in
                              any other way.

Shareholder Rights            You, or your estate or heirs, have no rights as a
                              shareholder of the Bank until a certificate for
                              the Shares has been issued. No adjustments are
                              made for dividends or other rights if the
                              applicable record date occurs before your share
                              certificate is issued, except as described in the
                              Plan.

Adjustments                   In the event of a stock split, a stock dividend
                              or a similar change in the Bank's Common Stock,
                              the number of Shares covered by this

                              merger, liquidation or reorganization in the
                              event the Bank is subject to such corporate
                              activity.

Applicable Law                This Agreement will be interpreted and enforced
