                                  ARTICLE XIII

                           RIGHTS OF INDEMNIFICATION

     The Corporation shall indemnify each of its officers and Directors,
whether or not then in office, and their executors, administrators and heirs,
against all reasonable expenses actually and necessarily incurred by them
(including, but not limited to, judgements, costs and counsel fees) in
connection with the defense of any litigation to which he may have been made a
party because he is, or was, a Director or officer of the Corporation. He shall
have no right to reimbursement, however, in relation to matters as to which he
has been adjudged liable for gross negligence or willful misconduct in the
performance of his duties, or was derelict in the performance of his duties by
reason of willful misconduct, bad faith, gross negligence, or reckless
disregard of the duties of his office. The right to indemnification shall also
apply to the expenses of suits which are compromised or settled, if the Court
having jurisdiction of the action shall approve such settlement.

     The foregoing rights of indemnification shall be in addition to, and not
exclusive of, all other rights to which such Director or officer may be
entitled.
