         The Corporation shall indemnify and advance expenses to any person
who was or is a party or is threatened to be made a party to any threatened,
pending or completed action, suit or proceeding, whether civil, criminal,
administrative or investigative (whether or not by or in the right of the

the Corporation, against expenses (including attorneys' fees), judgments,
fines and amounts paid in settlement actually and reasonably incurred by him
in connection with such action, suit or proceeding to the fullest extent
permitted by the General Corporation Law as the same exists or may hereafter
be amended; provided, however, that the Corporation shall be required to
indemnify a director or officer in connection with a proceeding initiated by

by the Board of Directors of the Corporation.

                                  ARTICLE XI

                                 MISCELLANEOUS

holders of a majority of the shares then entitled to vote at an election of
directors, except as otherwise provided by law. In furtherance and not in
limitation of the powers conferred by statue, the board of directors of the
Corporation is expressly authorized to make, alter or repeal the by-laws of
the Corporation.

                                  ARTICLE XII

                                 SEVERABILITY

         If any provisions contained in this Certificate of Incorporation
shall for any reason be held invalid, illegal or unenforceable in any respect,
such invalidity, illegality or unenforceability shall not invalidate the
entire Certificate of Incorporation or any other provisions hereof. Such
provision shall be deemed to be modified to the extent necessary to render it
valid and enforceable and if no such modification shall render it valid and
enforceable, then the Certificate of Incorporation shall be construed as if
not containing such provision.
