     prior act of the directors which would have been valid if such By-Laws had

effect, and such right to indemnification shall continue as to a person who has
ceased to be a director or officer of the Corporation and shall inure to the
benefit of his or her heirs, executors and personal and legal representatives;
PROVIDED, HOWEVER, that, except for proceedings to enforce rights to
indemnification, the Corporation shall not be obligated to indemnify any

omissions occurring prior to such repeal or modification.

Board of Directors or in the By-Laws of the Corporation.

          NINTH:  Notwithstanding any other provision of these Articles of
Incorporation or the By-Laws of the Corporation (and notwithstanding the fact
that a lesser percentage may be specified by law, these Articles of
Incorporation or the By-Laws of the Corporation), the affirmative vote of the
holders or seventy-five percent (75%) or more of the outstanding voting stock,
