                                INDEMNIFICATION

       Section 1. The corporation shall indemnify any person who was or is a
party or is threatened to be made a party to any action, suit or proceeding,
whether civil, criminal, administrative or investigative (including any action
by or in the right of the corporation) by reason of the fact that he is or was
a director, officer, employee or agent of the corporation, or is or was serving
at the request of the corporation as a director, officer, employee or agent of
another business, foreign or nonprofit corporation, partnership, joint venture
or other enterprise, 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 if he acted in good faith and
in a manner he reasonably believed to be in or not opposed to the best
interests of the corporation, and, with respect to any criminal action or
proceeding, had no reasonable cause to believe his conduct was unlawful;
provided that in case of actions by or in the right of the corporation, the
indemnity shall be limited to expenses (including attorneys' fees and amounts
paid in settlement not exceeding, in the judgment of the Board of Directors,
the



                                      -23-
   24
estimated expense of litigating the action to conclusion) actually and
reasonably incurred in connection with the defense or settlement of such action
and no indemnification shall be made in respect of any claim, issue or matter
as to which such person shall have been adjudged to be liable for negligence or
misconduct in the performance of his duty to the corporation unless and only to
the extent that the court shall determine upon application that, despite the
adjudication of liability but in view of all the circumstances of the case, he
is fairly and reasonably entitled to indemnity for such expenses which the
court shall deem proper. The termination of any action, suit or proceeding by
judgment, order, settlement, conviction, or upon a plea of nolo contendere or
its equivalent, shall not, of itself, create a presumption that the person did
not act in good faith and in a manner which he reasonably believed to be in or
not opposed to the best interests of the corporation, and, with respect to any
criminal action or proceeding, had reasonable cause to believe that his conduct
was unlawful.

       Section 2. To the extent that a director, officer, employee or agent of
the corporation has been successful on the



                                      -24-
   25
the merits or otherwise in defense of any such action, suit or proceeding, or
in defense of any claim, issue or matter therein, he shall be indemnified
against expenses (including attorneys' fees) actually and reasonably incurred
by him in connection therewith.

       Section 3. The indemnification hereunder (unless ordered by the court)
shall be made by the corporation only as authorized in a specific case upon a
determination that the applicable standard of conduct has been met. Such
determination shall be made (1) by the Board of Directors by a majority vote of
a quorum consisting of directors who were not parties to such action, suit or
proceeding or (2) if such a quorum is not obtainable or a quorum of
