hand or given to a director orally (whether by telephone or in person) or
mailed or telegraphed to a director at his residence or usual place of
business, provided, however, that if notice of less than 72 hours is given it
may not be mailed.  If mailed, the notice shall be deemed to have been given

the notice shall be deemed to have been given when the contents of the
telegram are transmitted to the telegraph service with instructions that the
telegram immediately be

or omissions not in good faith or which involve intentional misconduct or a
knowing violation of law, c) under Section 174 of the Delaware General
Corporation Law, or d) for any transaction from which the director derived an
improper personal benefit.  Such right of indemnification shall continue as to
a person who has ceased to be a director, officer, employee or agent and shall
inure to the benefit of the heirs, executors and administrators of such
person.  The indemnification provided for herein shall not be deemed exclusive
of any other rights to which those seeking indemnification may be entitled
under the Certificate of Incorporation of the Corporation, any agreement, vote
of stockholders or disinterested directors or otherwise.

another corporation, partnership, joint venture, trust or other enterprise,
against any liability asserted against him and incurred by him in any such
capacity, or arising out of his 











































20

status as such, whether or not the Corporation would have the power to
indemnify him against such liability under the provisions of Section 1 of the
By-laws or under Section 145 of the General Corporation Law or any other
provision of law.
