                     PENNSYLVANIA BUSINESS CORPORATION LAW
 
                         SUBCHAPTER D. INDEMNIFICATION
 
     1741 THIRD-PARTY ACTIONS. -- Unless otherwise restricted in its bylaws, a
business corporation shall have power to indemnify any person who was or is a
party or threatened to be made a party to any threatened, pending or completed
action or proceeding, whether civil, criminal, administrative or investigative
(other than an action by or in the right of the corporation), by reason of the
fact that he is or was a representative of the corporation, or is or was serving
at the request of the corporation as a representative of another domestic or
foreign corporation for profit or not-for-profit, partnership, joint venture,
trust or other enterprise, against expenses (including attorney's fees),
judgments, fines and amounts paid in settlement actually and reasonably incurred
by him in connection with the action 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 proceeding, had
no reasonable cause to believe his conduct was unlawful. The termination of any
action or proceeding by judgment, order, settlement or 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 that he reasonably
believed to be in, or not opposed to, the best interests of the corporation and,
with respect to any criminal proceeding, had reasonable cause to believe that
his conduct was unlawful.
 
     1742 DERIVATIVE AND CORPORATE ACTIONS. -- Unless otherwise restricted in
its bylaws, a business corporation shall have power to indemnify any person who
was or is a party, or is threatened to be made a party, to any threatened,
pending or completed action by or in the right of the corporation to procure a
judgment in its favor by reason of the fact that he is or was a representative
of the corporation or is or was serving at the request of the corporation as a
representative of another domestic or foreign corporation for profit or
not-for-profit, partnership, joint venture, trust or other enterprise, against
expenses (including attorneys' fees) actually and reasonably incurred by him in
connection with the defense or settlement of the action 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. Indemnification shall not be made under this
section in respect of any claim, issue or matter as to which the person has been
adjudged to be liable to the corporation unless and only to the extent that the
court of common pleas of the judicial district embracing the county in which the
registered office of the corporation is located or the court in which the action
was brought determines upon application that, despite the adjudication of
liability but in view of all the circumstances of the case, the person is fairly
and reasonably entitled to indemnity for the expenses that the court of common
pleas or other court deems proper.
 
     1743 MANDATORY INDEMNIFICATION. -- To the extent that a representative of a
business corporation has been successful on the merits or otherwise in defense
of any action or proceeding referred to in Section 1741 (relating to third-party
actions) or 1742 (relating to derivative and corporate actions) or in defense of
any claim, issue or matter therein, he shall be indemnified against expenses
(including attorney fees) actually and reasonably incurred by him in connection
therewith.
 
     1744 PROCEDURE FOR EFFECTING INDEMNIFICATION. -- Unless ordered by a court,
any indemnification under Section 1741 (relating to third-party actions) or 1742
(relating to derivative and corporate actions) shall be made by the business
corporation only as authorized in the specific case upon a determination that
indemnification of the representative is proper in the circumstances because he
has met the applicable standard of conduct set for in those sections. The
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 the action or proceeding;
 
          (2) if such a quorum is not obtainable or if obtainable and a majority
     vote of a quorum of disinterested directors so directs, by independent
     legal counsel in a written opinion; or
 
          (3) by the shareholders.
 
     1745 ADVANCING EXPENSES. -- Expenses (including attorneys' fees) incurred
in defending any action or proceeding referred to in this subchapter may be paid
by a business corporation in advance of the final disposition of the action or
proceeding upon receipt of an undertaking by or on behalf of the representative
to repay the amount if it is ultimately determined that he is not entitled to be
indemnified by the corporation as authorized in this subchapter or otherwise.

     1746 SUPPLEMENTARY COVERAGE. -- (a) General rule. -- The indemnification
and advancement of expenses provided by, or granted pursuant to, the other
sections of this subchapter shall not be deemed exclusive of any other rights to
which a person seeking indemnification or advancement of expenses may be
entitled under any bylaw, agreement, vote of shareholders or disinterested
directors or otherwise, both as to action in his official capacity and as to
action in another capacity while holding that office. Section 1728 (relating to
interested directors or officers; quorum) and, in the case of a registered
corporation, section 2538 (relating to approval of transactions with interested
shareholders) shall be applicable to any bylaw, contract or transaction
authorized by the directors under this section. A corporation may create a fund
of any nature, which may, but need not be, under the control of a trustee, or
otherwise secure or insure in any manner its indemnification obligations,
whether arising under or pursuant to this section or otherwise.
 
     (b) When indemnification is not to be made. -- Indemnification pursuant to
subsection (a) shall not be made in any case where the act or failure to act
giving rise to the claim for indemnification is determined by a court to have
constituted willful misconduct or recklessness. The articles may not provide for
indemnification in the case of willful misconduct or recklessness.
 
     (c) Grounds. -- Indemnification pursuant to subsection (a) under any bylaw,
agreement, vote of shareholders or directors or otherwise may be granted for any
action taken and may be made whether or not the corporation would have the power
to indemnify the person under any other provision of law except as provided in
this section and whether or not the indemnified liability arises or arose from
any threatened, pending or completed action by or in the right of the
corporation. Such indemnification is declared to be consistent with the public
policy of this Commonwealth.
 
     1747 POWER TO PURCHASE INSURANCE. -- Unless otherwise restricted in its
bylaws, a business corporation shall have power to purchase and maintain
insurance on behalf of any person who is or was a representative of the
corporation or is or was serving at the request of the corporation as a
representative of another domestic or foreign corporation for profit or
not-for-profit, 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 status as such, whether or not the corporation would have the
power to indemnify him against that liability under the provisions of this
subchapter. Such insurance is declared to be consistent with the public policy
of this Commonwealth.
 
     1748 APPLICATION TO SURVIVING OR NEW CORPORATIONS. -- For the purposes of
this subchapter, references to "the corporation" include all constituent
corporations absorbed in a consolidation, merger or division, as well as the
surviving or new corporations surviving or resulting therefrom, so that any
person who is or was a representative of the constituent, surviving or new
corporation, or is or was serving at the request of the constituent, surviving
or new corporation as a representative of another domestic or foreign
corporation for profit or not-for-profit, partnership, joint venture, trust or
other enterprise, shall stand in the same position under the provisions of this
subchapter with respect to the surviving or new corporation as he would if he
had served the surviving or new corporation in the same capacity.
 
     1749 APPLICATION TO EMPLOYEE BENEFIT PLANS. -- For purposes of this
subchapter:
 
          (1) References to "other enterprises" shall include employee benefit
     plans and references to "serving at the request of the corporation" shall
     include any service as a representative of the business corporation that
     imposes duties on, or involves services by, the representative with respect
     to an employee benefit plan, its participants or beneficiaries.
 
          (2) Excise taxes assessed on a person with respect to an employee
     benefit plan pursuant to applicable law shall be deemed "fines."
 
          (3) Action with respect to an employee benefit plan taken or omitted
     in good faith by a representative of the corporation in a manner he
     reasonably believed to be in the interest of the participants and
     beneficiaries of the plan shall be deemed to be action in a manner that is
     not opposed to the best interests of the corporation.
 
     1750 DURATION AND EXTENT OF COVERAGE. -- The indemnification and
advancement of expenses provided by, or granted pursuant to, this subchapter
shall, unless otherwise provided when authorized or ratified, continue as to a
person who has ceased to be a representative of the corporation and shall inure
to the benefit of the heirs and personal representative of that person.
