in paragraph 16.2 of the Plan (each referred to as an "Agreement and
collectively as the "Agreements");

     WHEREAS, the Plan (in Section 15) and the Agreements (in Section 8) provide
that Bancorp has the right to amend the Agreements; and

option granted to Optionee under each of the Agreements shall become fully
vested and exercisable on the date of the Optionee's retirement on or after age
85 or upon the Optionee's disability or death.

     NOW, THEREFORE, each of the Agreements is hereby amended effective as of

     Section 2 (Exercisability) is amended in each Agreement by adding a new
sentence to the end of such section as follows:

     Notwithstanding the preceding provisions of this paragraph, upon the
retirement of Optionee on or after age 85 or upon the disability or death of
Optionee, this option shall be exercisable in full and not only as to those
shares with respect to which installments, if any, have then accrued.
