                                  ARTICLE VIII

                                INDEMNIFICATION

         Section 1.(a)  The Corporation shall indemnify, in the manner and to
the full extent authorized by law (as now in effect or later amended), any
person who was or is a witness in or a party to, or who is threatened to be
made a party to, any action, suit or proceedings, whether criminal, civil,
administrative or investigative, by reason, in whole or in part, of the fact
that he is or was a director or officer of the Corporation or any predecessor
of the Corporation or serves or served in any other corporation or enterprise
as director, officer, employee or agent at the request of the Corporation or
any predecessor of the Corporation.

     (b)         Without limitation of subsection (a) above, the Corporation
shall indemnify any person who was or is a witness, 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 (other
than an action by or in the right of the Corporation or any predecessor of the
Corporation) by reason of the fact that such person is or was, at any time
prior to or during which this Article VIII is in effect, a director or officer
of the Corporation or any predecessor of the Corporation, or is or was, at any
time prior to or during which this Article VIII is in effect, serving at the
request of the Corporation or any predecessor of the Corporation as a director,
officer, employee or agent of another corporation, partnership, joint venture,
trust, other enterprise or employee benefit plan against reasonable expenses
(including attorneys' fees), judgments, fines, penalties, amounts paid in
settlement and other liabilities actually and reasonably incurred by such
person in connection with such action, suit or proceeding if such person acted
in good faith and in a manner he reasonably believed to be in or not opposed to
the best interests of the Corporation or any predecessor of the Corporation,
and, with respect to any





                                     -14-
   15
criminal action or proceeding, had no reasonable cause to believe that his
conduct was unlawful.  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 such 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 or any predecessor of the
Corporation, and, with respect to any criminal action or proceeding, had
reasonable cause to believe that his conduct was unlawful.

     (c)         Without limitation of subsection (a) above, the Corporation
shall indemnify any person who was or is a witness, a party or is threatened to
be made a party to any threatened, pending or completed action or suit by or in
the right of the Corporation or any predecessor of the Corporation to procure a
judgment in its favor by reason of the fact that such person is or was, at any
time prior to or during which this Article VIII is in effect, a director or
officer of the Corporation or any predecessor of the Corporation, or is or was,
at any time prior to or during which this Article VIII is in effect, serving at
the request of the Corporation or any predecessor of the Corporation as a
director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise against reasonable expenses (including
attorneys' fees) and amounts paid in settlement, actually and reasonably
incurred by such person in connection with the defense or settlement of such
action or suit if such person 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 the amounts paid in settlement, the settlement is determined to
be in the best interests of the Corporation; provided, that no indemnification
shall be made under this subsection (c) in respect of any claim, issue or
matter as to which such person shall have been adjudged to be liable to the
Corporation unless and only to the extent that the Delaware Court of Chancery,
or other court of appropriate jurisdiction, shall determine upon





                                     -15-
   16
application that, despite the adjudication of liability but in view of all the
circumstances of the case, such person is fairly and reasonably entitled to
indemnity of such expenses which the Delaware Court of Chancery, or other court
of appropriate jurisdiction, shall deem proper.

     (d)         Any indemnification under subsections (b) or (c) (unless
ordered by the Delaware Court of Chancery or other court of appropriate
jurisdiction) shall be made by the Corporation only as authorized in the
specific case upon a determination that indemnification of such person is
proper in the circumstances because he has met the applicable standard of
conduct set forth in subsections (b) and (c).  Such determination shall be made
(1) by the board of directors by a majority vote of a quorum consisting of
directors not parties to such action, suit or proceeding; or (2) if such a
quorum is not obtainable, or, even if obtainable a quorum of disinterested
directors so directs, by independent legal counsel, selected by the board of
directors; or (3) by the stockholders.  In the event a determination is made
under this subsection (d) that the director or officer has met the applicable
standard of conduct as to some matters but not as to others, amounts to be
indemnified may be reasonably prorated.

     (e)         In addition to and without limitation of subsections (b) or
(c) above, expenses incurred by a person who is or was a director or officer of
the Corporation, in appearing at, participating in or defending any threatened,
pending or completed action, suit or proceeding, whether civil, criminal,
administrative or investigative, shall be paid by the Corporation at reasonable
intervals in advance of the final disposition of such action, suit or
proceeding upon receipt of an undertaking by or on behalf of the director or
officer to repay such amount if it shall ultimately be determined that he is
not entitled to be indemnified by the Corporation as authorized by this Article
VII.

     (f)         If a claim under this Article VIII is not paid in full by the
Corporation within ninety days after a written claim has been received by the
Corporation, the claimant may at any





                                     -16-
   17
time thereafter bring suit against the Corporation to recover the unpaid amount
of the claim and, if successful in whole or in part, the claimant shall be
entitled to be paid also the expense of prosecuting such claim.  It shall be a
defense to any such action (other than an action brought to enforce a claim for
expenses incurred in defending any proceeding in advance of its final
disposition where the required undertaking, if any is required, has been
tendered to the Corporation) that the claimant has not met the standards of
conduct which make it permissible under the Delaware General Corporation Law
for the Corporation to indemnify the claimant for the amount claimed, but the
burden of proving such defense shall be on the Corporation.  Neither the
failure of the Corporation (including its board of directors, independent legal
counsel or its stockholders) to have made a determination prior to the
commencement of such action that indemnification of the claimant is proper in
the circumstances because he or she has met the applicable standard of conduct
set forth in the Delaware General Corporation Law, nor an actual determination
by the Corporation (including its board of directors, independent legal counsel
or its stockholders) that the claimant has not met such applicable standard of
conduct, shall be a defense to the action or create a presumption that the
claimant has not met the applicable standard of conduct.

     (g)         It is the intention of the Corporation to indemnify the
persons referred to in this Article VIII to the fullest extent permitted by law
(as now in effect or later amended) and with respect to any action, suit or
