representing at least 66 2/3% of the voting power of the then outstanding voting
stock of the Corporation entitled to vote in elections of directors generally,
voting together as a single class, shall be required to amend, repeal or adopt

heirs, executors and administrators of such persons and the Corporation may
purchase and maintain insurance on behalf of any director or officer to the
extent permitted by section 145 of the GCL.

                      Neither the amendment nor repeal of this Article EIGHTH,
nor the adoption of any provision of this Certificate of Incorporation
inconsistent with this Article EIGHTH, shall eliminate or reduce the effect of
this Article EIGHTH in respect of any matter occurring, or any cause of action,
suit or claim that, but for this Article EIGHTH, would accrue or arise, prior to
such amendment, repeal or adoption of an inconsistent provision.

        NINTH: The Corporation reserves the right to amend, alter, change or
repeal any provision contained in this Certificate of Incorporation, in the
