acts or omissions not in good faith or which involve intentional misconduct or a
knowing violation of law, (iii) under Section 174



of Title 8 of the Delaware General Corporation Law, or (iv) for any transaction
from which the director derived an improper personal benefit.

      If the Delaware General Corporation Law is amended to authorize corporate

as to a person who has ceased to be a director or officer, as the case may be,
and shall inure to the benefit of such person's heirs, executors and personal
and legal representatives. These rights of indemnification shall not be
exclusive of any other right that any person may have or hereafter acquire under
this Certificate of Incorporation, the Bylaws, any statute, agreements, vote of
shareholders or disinterested directors or otherwise. Any repeal or modification
of these indemnification provisions shall not adversely affect any rights to
indemnification any person may have at the time of such repeal or modification

modification.
