                                  ARTICLE XII.

                   Indemnification of Directors and Officers
                   -----------------------------------------

     (a) The Corporation hereby indemnifies and agrees to hold harmless from
claim, liability, loss or judgment any Director or officer made a party or
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, suit or proceeding by or on behalf of the Corporation to
procure a judgment in its favor), brought to impose a liability or penalty on
such person for an act alleged to have been committed by such person in his
capacity as Director, officer, employee or agent of the Corporation or any other
corporation, partnership, joint venture, trust or other enterprise in which he
served at the request of the Corporation, against judgments, fines, amounts paid
in settlement and reasonable expenses, including attorneys' fees actually and
reasonably incurred as a result of such action, suit or proceeding or any appeal
thereof, if, such person acted in good faith in the reasonable belief that such
action was in, or not opposed to, the best interests of the Corporation, and in
criminal actions or proceedings, without reasonable ground for belief that such
action was unlawful. The termination of any such action, suit or proceeding by
judgment, order, settlement, conviction or upon a plea of nolo contendere or its
equivalent shall not create a presumption that any such Director or officer did
not act in good faith in the reasonable belief that such action was in, or not
opposed to, the best interests; of the Corporation. Such person shall not be
entitled to indemnification in relation to matters as to which such person has
been adjudged to have been guilty of gross negligence or willful misconduct in
the performance of his duties to the Corporation.

                                      -5-
<PAGE>
 
     (b) Any indemnification under paragraph (a) shall be made by the
Corporation only as authorized in the specific case upon a determination that
amounts for which a Director or officer seeks indemnification were properly
incurred and that such Director or officer 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 that, with respect to any criminal action or proceeding, he had
no reasonable ground for belief that such action was unlawful.  Such
determination shall be made either (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) by a majority vote of a quorum consisting of
shareholders who were not parties to such action, suit or proceeding.

     (c) The Corporation shall be entitled to assume the defense of any person
seeking indemnification pursuant to the provisions of paragraph (a) above upon a
preliminary determination by the Board of Directors that such person has met the
applicable standards of conduct set forth in paragraph (a) above, and upon
receipt of an undertaking by such person to repay all amounts, expended by the
Corporation in such defense, unless it shall ultimately be determined that such
person is entitled to be indemnified by the Corporation as authorized in this
article.  If the Corporation elects to assume the defense, such defense shall be
conducted by counsel chosen by it and not objected to in writing for valid
reasons by such person.  In the event that the Corporation elects to assume the
defense of any such person and retains such counsel, such person shall bear the
fees and expenses of any additional counsel retained by him, unless there are
conflicting interests between or among such person and other parties represented
in the same action, suit or proceeding by the counsel retained by the
Corporation, that are, for valid reasons, objected to in writing by such person,
in which case the reasonable

                                      -6-
<PAGE>
 
expenses of such additional representation shall be within the scope of the
indemnification intended if such person is ultimately determined to be entitled
thereto as authorized in this article.

     (d) The foregoing rights of indemnification shall not be deemed to limit in
any way the power of the Corporation to indemnify under any applicable law.

                                 ARTICLE XIII.

                             Financial Information
                             ---------------------

     The Corporation shall not be required to prepare and provide a balance
sheet or a profit and loss statement to its shareholders, nor shall the
Corporation be required to file a balance sheet or profit and loss statement in
its registered office. This provision shall be deemed to have been ratified by
the shareholders each year hereafter unless a resolution to the contrary has
been adopted by the shareholders.

                                  ARTICLE XIV.

                                   Amendment
                                   ---------

     These Articles of Incorporation may be amended in any manner now or
hereafter provided for by law and all rights conferred upon shareholders
hereunder are granted subject to this reservation.
