subsidiary corporation, or during the 90 day period referred to in Paragraph 4
hereof, this option shall expire one (1) year after the date of Optionee's death
or on the day specified in Paragraph 2 hereof, whichever is earlier. After
Optionee's death but before such expiration, the persons to whom Optionee's
rights under this option shall have passed by Will or by the applicable laws of
descent and distribution or the executor or administrator of Optionee's estate

installments had accrued under Paragraph 2 hereof as of the date on which
Optionee ceased to be employed by the Bank or a subsidiary corporation. If the
Optionee terminates his employment because of a disability (as defined in
Section 105(d)(4) of the Internal Revenue Code of 1986, as amended from time to

termination, or before the expiration date specified n paragraph 2 hereof,
whichever is earlier.

corporation to employ Optionee for any period, nor shall it interfere in any way
with the right of the Bank or a subsidiary corporation to reduce Optionee's
compensation.

      8. Privileges of Stock Ownership. Optionee shall have no rights as a
stockholder with respect to the Bank's stock subject to this option until the
date of issuance of stock certificates to Optionee. Except as provided in the
Plan, no adjustment will be made for dividends or other rights for which the
record date is prior to the date such stock certificates are issued.

      9. Modification and Termination by Board of Directors. The rights of
Optionee are subject to modification and termination upon the occurrence of
certain events as provided in Sections 13 and 14 of the Plan.

acquiring shares upon exercise of this option, will notify the Bank not more
than five (5) days after any sale or other disposition of such shares. No shares
issuable upon the exercise of this option shall be issued and delivered unless

to the issuance and sale of such shares, and all applicable listing requirements
of the securities exchanges, if any, on which shares of the Bank of the same
class are then listed shall have been complied with.
