      4. BOARD OF DIRECTORS

            4.1. POWERS; PERSONAL LIABILITY.

                  4.1.1. General rule. Unless otherwise provided by statute, all
powers vested by law in the corporation shall be exercised by or under the
authority of, and the business and affairs of the corporation shall be managed
under the direction of, the board of directors.

                  4.1.2. Standard of care; justifiable reliance. A director
shall stand in a fiduciary relation to the corporation and shall perform his or
her duties as a director, including duties as a member of any committee of the
board upon which the director may serve, in good faith, in a manner the director
reasonably believes to be in the best interests of the corporation and with such
care, including reasonable inquiry, skill and diligence, as a person of ordinary
prudence would use under similar circumstances. In performing his or her duties,
a director shall be entitled to rely in good faith on information, opinions,
reports or statements, including financial statements and other financial data,
in each case prepared or presented by any of the following:

                        4.1.2.1. One or more officers or employees of the
corporation whom the director reasonably believes to be reliable and competent
in the matters presented.

                        4.1.2.2. Counsel, public accountants or other persons as
to matters which the director reasonably believes to be within the professional
or expert competence of such person.

                        4.1.2.3. A committee of the board upon which the
director does not serve, duly designated in accordance with law, as to matters
within its designated authority, which committee the director reasonably
believes to merit confidence.

A director shall not be considered to be acting in good faith if the director
has knowledge concerning the matter in question that would cause his or her
reliance to be unwarranted.

                  4.1.3. Consideration of factors. In discharging the duties of
their respective positions, the board of directors, committees of the board and
individual directors may, in considering the best interests of the corporation,
consider the effects of any action upon employees, upon suppliers and


                                       12


customers of the corporation and upon communities in which offices or other
establishments of the corporation are located, and all other pertinent factors.
The consideration of those factors shall not constitute a violation of
subsection 4.1.2.

                  4.l.4. Presumption. Absent breach of fiduciary duty, lack of
good faith or self-dealing, actions taken as a director or any failure to take
any action shall be presumed to be in the best interests of the corporation.

                     4.1.5. Personal liability of directors.

                        4.1.5.1. A director shall not be personally liable, as
such, for monetary damages for any action taken, or any failure to take any
action, unless:

                        (i) the director has breached or failed to perform the
duties of his or her office under this section; and

                        (ii) the breach or failure to perform constitutes
self-dealing, willful misconduct or recklessness.

                        4.1.5.2. The provisions of paragraph (1) shall not apply
to the responsibility or liability of a director pursuant to any criminal
statute, or the liability of a director for the payment of taxes pursuant to
local, state or Federal law.

                  4.1.6. Notation of dissent. A director who is present at a
meeting of the board of directors, or of a committee of the board, at which
action on any corporate matter is taken shall be presumed to have assented to
the action taken unless his or her dissent is entered in the minutes of the
meeting or unless the director files a written dissent to the action with the
secretary of the meeting before the adjournment thereof or transmits the dissent
in writing to the secretary of the corporation immediately after the adjournment
of the meeting. The right to dissent shall not apply to a director who voted in
favor of the action. Nothing in this section shall bar a director from asserting
that minutes of the meeting incorrectly omitted his or her dissent if, promptly
upon receipt of a copy of such minutes, the director notifies the secretary in
writing, of the asserted omission or inaccuracy.

the board of directors.

the expiration of the term for which he or she was elected and until a successor
has been selected and qualified or until his or her earlier death, resignation
or removal. A decrease in the number of directors shall not have the effect of
shortening the term of any incumbent director.

                  4.3.3. Resignation. Any director may resign at any time upon
written notice to the corporation. The resignation shall be effective upon
receipt thereof by the corporation or at such subsequent time as shall be
specified in the notice of resignation.

including vacancies resulting from an increase in the number of directors, may
be filled by a majority vote of the remaining members of the board though less
than a quorum, or by a sole remaining director, and each person so selected
shall be a director to serve for the balance of the unexpired term, and until a
successor has been selected and qualified or until his or her earlier death,
resignation or removal.

                  4.4.2. Action by resigned directors. When one or more
directors resign from the board effective at a future date, the directors then
in office, including those who have so resigned, shall have power by the
applicable vote to fill the vacancies, the vote thereon to take effect when the

directors, or any class of the board, or any individual director may be removed

board or any one or more directors are so removed, new directors may be elected
at the same meeting.

                  4.5.2. Removal by the board. The board of directors may
declare vacant the office of a director who has


                                       14


been judicially declared of unsound mind or who has been convicted of an offense
punishable by imprisonment for a term of more than one year or if, within 60
days after notice of his or her selection, the director does not accept the
office either in writing or by attending a meeting of the board of directors.

            4.6. PLACE OF MEETINGS. Meetings of the board of directors may be

shall be in such form as approved by the board of directors, and shall state

president and by the secretary or an assistant secretary or the treasurer or an
assistant treasurer, and shall bear the corporate seal, which may be a
facsimile, engraved or printed; but where such certificate is signed by a
transfer agent or a registrar the signature of any corporate officer upon such
certificate may be a facsimile, engraved or printed. In case any officer who has
signed, or whose facsimile signature has been placed upon, any share certificate
shall have ceased to be such officer because of death, resignation or otherwise,
before the certificate is issued, it may be issued with the same effect as if
the officer had not ceased to be such at the date of its issue. The provisions

directors may, in its discretion, cause a new certificate or certificates to be
issued to such holder, in case of mutilation of the certificate, upon


                                       19


the surrender of the mutilated certificate or, in case of loss or destruction of
the certificate, upon satisfactory proof of such loss or destruction and, if the
board of directors shall so determine, the deposit of a bond in such form and in
such sum, and with such surety or sureties, as it may direct.

      7. INDEMNIFICATION OF DIRECTORS, OFFICERS AND OTHER AUTHORIZED
REPRESENTATIVES

            7.1. SCOPE OF INDEMNIFICATION.

                  7.1.1. General rule. The corporation shall indemnify an
indemnified representative against any liability incurred in connection with any
proceeding in which the indemnified representative may be involved as a party or
otherwise by reason of the fact that such person is or was serving in an
indemnified capacity, including, without limitation, liabilities resulting from
any actual or alleged breach or neglect or duty, error, misstatement or
misleading statement, negligence, gross negligence or act giving rise to strict
or products liability, except:

                        7.1.1.1. where such indemnification is expressly
prohibited by applicable law;

                        7.1.1.2. where the conduct of the indemnified
representative has been finally determined pursuant to Section 7.6 or otherwise:

                        (i) to constitute willful misconduct or recklessness
within the meaning of 15 Pa.C.S. ss.513(b) and ss.1746(b) and 42 Pa.C.S.
ss.8365(b) or any superseding provision of law sufficient in the circumstances
to bar indemnification against liabilities arising from the conduct; or

                        (ii) to be based upon or attributable to the receipt by
the indemnified representative from the corporation of a personal benefit to
which the indemnified representative is not legally entitled; or

                        7.1.1.3. to the extent such indemnification has been
finally determined in a final adjudication pursuant to Section 7.6 to be
otherwise unlawful.

                  7.1.2. Partial payment. If an indemnified representative is
entitled to indemnification in respect of a portion, but not all, of any
liabilities to which such person may be subject, the corporation shall indemnify
such indemnified representative to the maximum extent for such portion of the
liabilities.

                  7.1.3. Presumption. The termination of a 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 indemnified
representative is not entitled to indemnification.

                  7.1.4. Definitions. For purposes of this Article:

                        7.1.4.1. "indemnified capacity" means any and all past,
present and future service by an indemnified representative in one or more
capacities as a director, officer, employee or agent of the corporation, or, at
the request of the corporation, as a director, officer, employee, agent,
fiduciary or trustee of another corporation, partnership, joint venture, trust,
employee benefit plan or other entity or enterprise;

                        7.1.4.2. "indemnified representative" means any and all
directors and officers of the corporation and any other person designated as an
indemnified representative by the board of directors of the corporation (which
may, but not, include any person serving at the request of the corporation, as a
director, officer, employee, agent, fiduciary or trustee of another corporation,
partnership, joint venture, trust, employee benefit plan or other entity or
enterprise);

                        7.1.4.3. "liability" means any damage, judgment, amount
paid in settlement, fine, penalty, punitive damages, excise tax assessed with

completed action, suit, appeal or other proceeding of any nature, whether civil,
criminal, administrative or investigative, whether formal or informal, and
whether brought by or in the right of the corporation, a class of its security
holders or otherwise.

            7.2. PROCEEDINGS INITIATED BY INDEMNIFIED REPRESENTATIVES.
Notwithstanding any other provision of this Article, the corporation shall not
indemnify under this Article an indemnified representative for any liability
incurred in a proceeding initiated (which shall not be deemed to include
counter-claims or affirmative defenses) or participated in as an intervenor or
amicus curiae by the person seeking indemnification unless such initiation of or
participation in the proceeding is authorized, either before or after its
commencement, by the affirmative vote of a majority of the directors in office.
This section does not apply to a reimbursement of expenses incurred in
successfully prosecuting or defending an arbitration under


                                       21


Section 7.6 or otherwise successfully prosecuting or defending the rights of an
indemnified representative granted by or pursuant to this Article.

            7.3. ADVANCING EXPENSES. The corporation shall pay the expenses
(including attorneys' fees and disbursements) incurred in good faith by an
indemnified representative in advance of the final disposition of a proceeding
described in Section 7.1 the initiation of or participation in which is
authorized pursuant to Section 7.2 upon receipt of an undertaking by or on
behalf of the indemnified representative to repay the amount if it is ultimately
determined pursuant to Section 7.6 that such person is not entitled to be
indemnified by the corporation pursuant to this Article. The financial ability
of an indemnified representative to repay an advance shall not be a prerequisite
to the making of such advance.

            7.4. SECURING OF INDEMNIFICATION OBLIGATIONS. To further effect,
satisfy or secure the indemnification obligations provided herein or otherwise,
the corporation may maintain insurance, obtain a letter of credit, act as self-
insurer, create a reserve, trust, escrow, cash collateral or other fund or
account, enter into indemnification agreements, pledge or grant a security
interest in any assets or properties of the corporation, or use any other
mechanism or arrangement whatsoever in such amounts, at such costs, and upon
such other terms and conditions as the board of directors shall deem
appropriate. Absent fraud, the determination of the board of directors with
respect to such amounts, costs, terms and conditions shall be conclusive against
all security holders, officers and directors and shall not be subject to
voidability.

            7.5. PAYMENT OF INDEMNIFICATION. An indemnified representative shall
be entitled to indemnification within 30 days after a written request for
indemnification has been delivered to the secretary of the corporation.

            7.6. ARBITRATION.

                  7.6.1. General rule. Any dispute related to the right to
indemnification, contribution or advancement of expenses as provided under this
Article, except with respect to indemnification for liabilities arising under
the Securities Act of 1933 that the corporation has undertaken to submit to a
court for adjudication, shall be decided only by arbitration in the metropolitan
area in which the principal executive offices of the corporation are located at
the time, in accordance with the commercial arbitration rules then in effect of
the American Arbitration Association, before a panel of three arbitrators, one
of whom shall be selected by the corporation, the second of whom shall be
selected by the indemnified representative and third of whom shall be selected
by the other two arbitrators. In the


                                       22
