by statute, may be called by the President or by the Board of Directors, and

corporation entitled to vote at the meeting.

                  Section 3. Place of Meeting. The Board of Directors may
designate any place, either within or without the Commonwealth of Pennsylvania
unless otherwise prescribed by statute, as the place of meeting for any annual
meeting or for any special meeting called by the Board of Directors. A waiver of

If no designation is made, or if a special meeting be otherwise called, the
place of meeting shall be the registered office of the corporation in the
Commonwealth of Pennsylvania.

                  Section 4. Notice of Meeting. Written or printed notice
stating the place, day and hour of the meeting and, in case of a special

notice shall be deemed to be delivered when deposited in the United States mail,
addressed to the shareholder at his address as it appears on the stock transfer
books of the corporation, with postage thereon prepaid.

                  Section 5. Voting Lists. The officer or agent having charge of
the stock transfer books for shares of the corporation shall make, on the record
date, which shall be at least



five (5) days before each meeting of the shareholders, a complete list of the
shareholders entitled to vote at such meeting, or any adjournment thereof,
arranged in alphabetical order, with the address of and the number of shares
held by each, which list, for a period of five (5) days prior to such meeting,
shall be kept on file at the registered office of the corporation and shall be
subject to inspection by any shareholder at any time during usual business
hours. Such list shall also be produced and kept open at the time and place of
the meeting and shall be subject to the inspection of any shareholder during the
whole time of the meeting. The original stock transfer book shall be prima facie
evidence as to who are the shareholders entitled to examine such list or
transfer books or to vote at any meeting of shareholders.

                  Section 6. Quorum. The holders of shares constituting a
majority of the total voting power of the outstanding shares of the corporation
entitled to vote as provided for in Section 8 of this Article II, represented in
person or by proxy, shall constitute a quorum for the transaction of business at
all meetings of the shareholders except as otherwise provided by statute, the
Articles of Incorporation or these by-laws. If less than a majority of the
voting power so described of the outstanding shares are represented at a
meeting, the majority of the voting power of the corporation so represented may
adjourn the meeting from time to time without further notice. At such adjourned
meeting at which a quorum shall be present or represented, any business may be
transacted which might have been transacted at the meeting as originally
notified. The shareholders present at a duly organized meeting may continue to
transact business until adjournment, notwithstanding the withdrawal of enough
shareholders to leave less than a quorum.

meeting of shareholders or to express consent or dissent to corporate action in
writing without a meeting may authorize another person or persons to act for him
by proxy. Every proxy shall be executed in writing by the shareholder, or by his
duly authorized attorney in fact, and filed with the secretary of the
corporation. A proxy, unless coupled with an interest, shall be revocable at
will, notwithstanding any other agreement or any provision in the proxy to the
contrary, but the revocation of a proxy shall not be effective until notice
thereof has been given to the secretary of the corporation. No unrevoked proxy
shall be valid after eleven months from the date of its execution, unless a
longer time is expressly provided therein, but in no event shall a proxy, unless
coupled with an interest, be voted on after three years from the date of its
execution.

                  Section 8. Voting of Shares. Subject to the provisions of
Section 10 of this Article II each outstanding share of common Stock entitled to
vote shall be entitled to one vote upon each matter submitted to a vote at a
meeting of shareholders.

                  Section 9. Voting of Shares by Certain Holders. Shares
standing in the name of another corporation may be voted by an officer, agent or
proxy of such corporation without a transfer of such shares into his name.
Shares standing in the name of a trustee may be voted by him, either in person
or by proxy, but no trustee shall be entitled to vote shares held by him without
a transfer of such shares into his name.

                  Shares standing in the name of a receiver may be voted by such
receiver, and shares held by or under the control of a receiver may be voted by
such receiver without the



                                       2

transfer thereof into his name if authority so to do be contained in an
appropriate order of the court by which such receiver was appointed.

                  A shareholder whose shares are pledged shall be entitled to
vote such shares until the shares have been transferred into the name of the
pledgee, and thereafter the pledgee shall be entitled to vote the shares so
transferred.

                  Shares of its own stock belonging to the corporation or held
by it in a fiduciary capacity shall not be voted, directly or indirectly, at any
meeting, and shall not be counted in determining the total number of outstanding
shares at any given time.

law, at each election for Directors there shall be no cumulative voting and
every shareholder entitled to vote at such election shall have the right to
vote, in person or by proxy, the number of shares owned by him on the record
date according to the voting power which is provided for such shares in Section
8 of this Article II for as many persons as there are directors to be elected
and for whose election he has a right to vote.

                  Section 11. Informal Action by Shareholders. Unless otherwise
provided by law, any action which may be taken at a meeting of the shareholders,
may be taken without a meeting if a consent in writing, setting forth the action
so taken, shall be signed by all of the shareholders entitled to vote with
respect to the subject matter thereof.

                  Section 7. Manner of Acting. The act of the majority of the
directors present at a meeting at which a quorum is present shall be the act of
the Board of Directors.

resulting from an increase in the number of directors, occurring in the Board of
Directors may be filled by the affirmative vote of a majority of the remaining

                  Section 1. This corporation shall indemnify any person who was
or is 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



                                       6


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 corporation, 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 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. 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. This corporation shall indemnify any person who was
or is 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 to procure a
judgment in its favor 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
corporation, 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 such action or suit 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 except that 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 of
Common Pleas of the county in which the registered office of the corporation is
located or the court in which such action or suit was brought shall determine
upon 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
indemnify for such expenses which the Court of Common Pleas or such other court
shall deem proper.

                  Section 3. To the extent that a director, officer, employee or
agent of the corporation has been successful on the merits or otherwise in
defense of any action, suit or proceeding referred to in Sections 1 and 2 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 4. Any indemnification under Sections 1 and 2 of this
Article V (unless ordered by a court) shall be made by the corporation only as
authorized in the specific case upon a determination that indemnification of the
director, officer, employee or agent is proper in the circumstances because he
has met the applicable standard of conduct set forth in such section such
determination shall be made:

                  (a) 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



                                       7


                  (b) If such a quorum is not obtainable, or, even if obtainable
a majority vote of a quorum of disinterested directors so directs, by
independent legal counsel in a written opinion, or

                  (c) By the shareholders.

                  Section 5. Expenses incurred in defending a civil or criminal
action, suit or proceeding may be paid by the corporation in advance of the
final disposition of such action, suit or proceeding as authorized in the manner
provided in Section 3 upon receipt of an undertaking by or on behalf of the
director, officer, employee or agent to repay such amount unless it shall
ultimately be determined that he is entitled to be indemnified by the
corporation as authorized in this Article.

                  Section 6. The indemnification provided by this Article shall
not be deemed exclusive of any other rights to which those seeking
indemnification may be entitled under any by-law, 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 such office, and
shall continue as to a person who has ceased to be a director, officer, employee
or agent and shall inure to the benefit of the heirs, executors and
administrators of such a person.

                  Section 7. The corporation shall have the power to purchase
and maintain insurance on behalf of any person who 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
corporation, 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 such liability under the provisions of this
Article.

deliver any instrument in the name of any on behalf of the corporation, and such
authority may be general or confined to specific instances.

                  Section 2. Loans. No loans shall be contracted on behalf of
the corporation and no evidences of indebtedness shall be issued in its name
unless authorized by a resolution of the Board of Directors. Such authority may
be general or confined to specific instances.

                  Section 3. Checks, drafts, etc. All checks, drafts and other
orders for the payment of money, notes or other evidences of indebtedness issued
in the name of the corporation, shall be signed by such officer or officers,
agent or agents of the corporation and in such manner as shall from time to time
be determined by resolution of the Board of Directors.

                  Section 1. Certificates for Shares. Certificates representing
shares of the corporation shall be in such form as shall be signed by the
President and by the Secretary or by such other officers authorized by law and
by the Board of Directors so to do and shall be sealed with the corporate seal
which may be facsimile, engraved or printed but where such share certificate is
signed by a transfer agent or registrar the signature of any corporate officer
upon such certificate may be 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 by the
corporation with the same effect as if the officer had not ceased to be such at
the date of its issue. All certificates shall be consecutively numbered or
otherwise identified. The name and address of the person to whom the shares
represented thereby are issued, with the number of shares and date of issue,
shall be entered on the stock transfer books of the corporation. All
certificates surrendered to the corporation for transfer shall be cancelled and
no new certificate shall be issued until the former certificate for a like
number of shares shall have been surrendered and cancelled, except that in case
of a lost, destroyed or mutilated certificate a new one may be issued therefor
upon such terms and indemnity to the corporation as the Board of Directors may
prescribe.

                  Section 2. Transfer of Shares. Transfer of shares of the
corporation shall be made only on the stock transfer books of the corporation by
the holder of record thereof or by his legal representative, who shall furnish
proper evidence of authority to transfer, or by his attorney thereunto
authorized by power of attorney duly executed and filed with the Secretary of
the corporation, and on surrender for cancellation of the certificate for such
