                            MEETINGS OF SHAREHOLDERS

                  Section 1. Meetings of the shareholders shall be held at the
office of the Corporation at 2825 Penn Avenue, Pittsburgh, PA 15222 or at such
other place or places, either within or without the Commonwealth of Pennsylvania
as may from time to time be fixed or determined by the Board of Directors.

                  Section 2. The annual meeting of the shareholders shall be
held each year on such date within three (3) months following the close of the
fiscal year as shall be determined from time to time by the Board of Directors
and shall be held at a time and place determined by a resolution of the Board of
Directors. At such annual meeting, the shareholders shall elect the Board of
Directors, review reports of the affairs of the Corporation and transact any
other business which is within the powers of the shareholders.

                  Section 3. Notice of the annual meeting specifying the place,
date and hour of the meeting shall be given at least ten (10) days prior to the
meeting, to each shareholder entitled to vote thereat, being on record on the
date fixed as a record date, or, if no record date be fixed, then of record
thirty days next preceding the date of the meeting.

                  Section 4. Special meetings of the shareholders, for any
purpose or purposes, other than those regulated by statute or by the Articles of
Incorporation, may be called at any time by the President or by a majority of
the Board of Directors or by the holders of not less than twenty (20%) percent
of all shares issued and outstanding and entitled to vote at the particular





meeting which are provided with such right under the Pennsylvania Business
Corporation Law, upon written request delivered to the Secretary of the
Corporation. Such request shall state the purpose or purposes of the proposed
meeting. Upon receipt of any such request it shall be the duty of the Secretary
to call a special meeting of the shareholders to be held at such time, not less
than ten nor more than sixty (60) days thereafter, as the Secretary may fix. If
the Secretary shall neglect to issue such a call, the person or persons making
the request may issue the call.

                  Section 5. Notice of any special meeting of shareholders shall
be given by, or at the direction of, the Secretary or other authorized person,
stating the place, the date and hour and the general nature of the business to
be transacted thereat, shall be given to each shareholder entitled to vote
thereat at least ten (10) days prior to the date named for a meeting called to
consider a fundamental change or five (5) days prior to the day named for the
meeting and other case. If the Secretary or other authorized person neglects or
refuses to give notice of a meeting, the person or persons calling the meeting
may do so. In the case of a special meeting of shareholders, the notice shall
specify the general nature of the business to be transacted.

                  Section 6. Business transacted at all special meetings shall
be confined to the purposes stated in the call and matters germane thereto
unless all shareholders entitled to vote consent to the consideration of
additional business.

                  Section 7. The presence, in person or by proxy, of the holders
of a majority of the outstanding shares entitled to vote shall constitute a
quorum for the transaction of business at all meetings of the shareholders,
except as otherwise provided by law, by the Articles of Incorporation or by
these Bylaws. The shareholders present at a duly organized meeting can continue
to do business until adjournment, notwithstanding the withdrawal of enough
shareholders to leave less than a quorum to conduct business which might have
been transacted at the meeting as originally notified provided notification of
the meeting states that those shareholders who attended the adjourned meeting
shall constitute a quorum for the purpose of acting upon the matter. If,
however, any meeting of the shareholders cannot be organized because a quorum
has not attended, the shareholders entitled to vote thereat, present in person
or by proxy, shall have power, except as otherwise provided by statute, to
adjourn the meeting to such time and place as they may determine, but in the
case of any meeting called for the election of Directors, such meeting may be
adjourned only from day to day, or for such longer periods not exceeding fifteen
days each as the holders of a majority of the shares present in person or by
proxy shall direct, and those who attend the second of such adjourned meetings,
although less than a quorum, shall nevertheless constitute a quorum for the
purpose of electing Directors. At any 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 provided notification is given
of such quorum.

                  Section 8. When a quorum is present or represented at any
meeting, the vote of the holders of a majority of the stock having voting power,
present in person or represented by proxy, shall decide any question brought
before such meeting, unless the question is one upon


                                      - 2 -





which, by express provision of the statutes or of the Articles of Incorporation
or by these Bylaws, a different vote is required in which case such express
provision shall govern and control the decision of such question.

                  Section 9. At each shareholders' meeting, every shareholder
entitled to vote shall have the right of one vote for every share having voting
power standing in his or her name on the books of the Corporation. Unless a
record date shall have been fixed for the determination of the shareholders
entitled to vote at a shareholders' meeting, transferees of the shares which are
next preceding the date of such meeting shall not be entitled to vote at such
meeting. Unless demanded by a shareholder of the Corporation present in person
or by proxy at any meeting of the shareholders and entitled to vote thereat or
so directed by the Chairman of such meeting or required by law, the vote thereat
on any question need not be by written ballot. On a vote by written ballot, each
ballot shall be signed by the shareholder voting or in his or her name by his or
her proxy, if there be such a proxy, and shall state the number of shares voted
by him or her and the number of votes to which each share is entitled.

                  Section 10. Every shareholder entitled to vote may vote either
in person or by proxy. Every proxy shall be executed in writing by the
shareholder or by his or her 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. An
unrevoked proxy shall not be valid after three years from the date of its
execution unless a longer time is expressly provided for. A proxy shall not be
revoked by the death or incapacity of the maker unless, before the vote is
counted or the authority is exercised, written notice of such death or
incapacity is given to the Secretary of the Corporation.

                  Section 11. The officer or agent having charge of the transfer
books for shares of the Corporation shall make a complete list of the
shareholders entitled to vote at any meeting of shareholders, arranged in
alphabetical order, with the address of and number of shares held by each, which
list 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.

                  Section 12. Except for the action required by state law to be
taken at a meeting of the shareholders held after proper notice, any action
required to be taken at a meeting of the shareholders or a class of 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 who would be entitled to
vote at a meeting for such purpose and shall be filed with the Secretary of the
Corporation.

                  Section 13. One or more persons may participate in a meeting
of the shareholders of a business corporation by means of conference telephone
or similar communications


                                      - 3 -




equipment by means of which all persons participating in the meeting can hear
each other. Participation in a meeting pursuant to this section shall constitute
presence in person at the meeting.

                  Section 14. Shares of the Corporation standing in the name of
a trustee or other fiduciary and shares held by an assignee for the benefit of
creditors or by a receiver may be voted by the trustee, fiduciary, assignee or
receiver. A shareholder whose shares are pledged shall be entitled to vote the
shares until the shares have been transferred into the name of the pledgee, or a
nominee of the pledgee, but nothing herein shall affect the validity of a proxy
given to a pledgee or nominee.

                  Section 15. Where shares of the Corporation are held jointly
or as tenants in common by two or more persons, as fiduciaries or otherwise: (1)
if only one or more of such persons is present in person or by proxy, all of the
shares standing in the names of such persons shall be deemed to be represented
for the purpose of determining a quorum and the Corporation shall accept as the
vote of all the shares the vote cast by him or her or a majority of them; and
(2) if the persons are equally divided upon whether the shares held by them
shall be voted or upon the manner of voting the shares, the voting of the shares
shall be divided equally among the persons without prejudice to the rights of
the joint owners or the beneficial owners thereof among themselves. If there has
been filed with the Secretary of the Corporation a copy, certified by an
attorney at law to be correct, of the relevant portions of the agreement under
which the shares are held or the instrument by which the trust or estate was
created or the order of court appointing them or of an order of court directing
the voting of the shares, the person specified as having such voting power in
the latest document so filed, and only those persons, shall be entitled to vote
the shares but only in accordance therewith.

                  Section 16. At every meeting of the shareholders, the
president, or, in the president's absence, the officer designated by a majority
in interest of the shareholders of the Corporation present in person or by proxy
and entitled to vote, shall act as chairman. The secretary of the Corporation
shall act as secretary of all meetings of the shareholders and in the absence of
the secretary, the chairman of the meeting may appoint another person to so act
as secretary of the meeting.

                                   ARTICLE III

                                    DIRECTORS

                  Section 1. The number of Directors shall consist of one or
more members as shall be determined from time to time by the Board of Directors.
Directors shall be a natural person of full age who, need not be a resident of
this Commonwealth or a shareholder of the Corporation. Except as hereinafter
provided in the case of vacancies, Directors, other than those constituting the
first Board of Directors, shall be elected by the shareholders, and each

successor shall be elected and


                                      - 4 -

Director may resign at anytime 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. A
decrease in the number of Directors shall not have the effect of shortening the
term of any incumbent Director.

                  Section 2. Vacancies in the Board of Directors, 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 the sole remaining Director, and each person so elected shall be a
Director until his or her successor is elected by the shareholders at an
election at the next annual meeting of the shareholders or any special meeting
duly called for that purpose and held prior thereto.

                  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 resignations become effective.

                  Section 3. The business and affairs of the Corporation shall
be managed by its Board of Directors which may exercise all such powers of the
Corporation and do all such lawful acts and things as are not by statute or by
the Articles of Incorporation or by these Bylaws directed or required to be
exercised and done by the shareholders.

                  Section 4. The meetings of the Board of Directors may be held
at such place within or without this Commonwealth as the Board of Directors may
from time to time appoint or as may be designated in the notice of the meeting.
Written notice of every meeting of the Board of Directors shall be given to each
Director at least five days before the day named for the meeting. Neither the
business to be transacted at, nor the purpose of, any regular or special meeting
of the Board need be specified in the notice of the meeting.

                  Section 5. The first meeting of each newly elected Board may
be held at such time and place as shall be fixed by the shareholders at the
meeting at which such Directors were elected and no notice shall be necessary to
the newly elected Directors in order legally to constitute the meeting, provided
a majority of the whole Board shall be present; or it may convene at such time
and place as may be fixed by the consent in writing of all the Directors.

                  Section 6. Regular meetings of the Board may be held at such

least a majority of the Board at a duly convened meeting, or by unanimous
written consent. Notice of regular meetings of the Board shall be given to each
Director at least five days before each meeting.

                  Section 7. Special meetings of the Board may be called by the
President on one day's notice to each Director. Special Meetings may be called
on the written request of two Directors.

                  Section 8. At all meetings of the Board, the presence of a
majority of the Directors in office shall be necessary to constitute a quorum
for the transaction of business and the acts of a majority of the Directors
present and voting at a meeting at which a quorum is present shall be the acts
of the Board of Directors, except as may be otherwise specifically provided by
statute or by the Articles of Incorporation or by these Bylaws. If a quorum
shall not be present at any meeting of the Directors, the Directors present
thereat may adjourn the meeting from time to time, without notice other than
announcement at the meeting, until a quorum shall be present.

                  Section 9. Any action required or permitted to be taken at a
meeting of the Directors may be taken without a meeting if, prior or subsequent
to the action, a consent or consents thereto by all of the Directors in office
is filed with the Secretary of the Corporation.

                  Section 10. One or more Directors may participate in a meeting
of the Board of Directors of the Corporation by means of a conference telephone
or similar communications equipment by means of which all persons participating
in the meeting can hear each other. Participation in a meeting pursuant to this
Section shall constitute presence in person at the meeting.

                  Section 11. The Board of Directors may, by resolution adopted
by a majority of the Directors in office, establish an Executive Committee to

                  (1) The submission to shareholders of any action requiring

                  (3) The adoption, amendment or repeal of the Bylaws.

                  (4) The amendment or repeal of any resolution of the Board
                  that by its terms is amendable or repealable only by the
                  Board.



                                      - 6 -





                  (5) Action on matters committed by the Bylaws or resolution of
                  the Board of Directors to another committee of the Board.

members of the Executive Committee who may replace any absent or disqualified
member at any meeting of the Executive Committee or for the purposes of written
action by the Executive Committee. In the absence or disqualification of a

pleasure of the Board.

                  The Board of Directors may, by resolution adopted by a
majority of the Directors in office, establish such other committees as the
Board of Directors may deem fit; provided, however, that no such committee shall
have any power or authority as to the matters set forth in subparagraphs 1
through and including 5 above.

                            COMPENSATION OF DIRECTORS

                  Section 12. Directors may be compensated for their services by
Resolution of the Board and a fixed sum, and expenses of attendance if any, may
be allowed for attendance at each regular or special meeting of the Board or at
meetings of the committees, provided, that nothing herein contained shall be
construed to preclude any Director from serving the Corporation in any other
capacity and receiving compensation therefor.

                          LIABILITY AND INDEMNIFICATION

                  Section 13. Except for responsibility or liability of a
Director pursuant to any criminal statute or for payment of taxes pursuant to
local, state or Federal law, a Director of the Corporation shall not be
personally liable for monetary damages for any action taken or any failure to
take any action unless (a) such director has breached or failed to perform his
or her fiduciary duties as provided herein and (b) the breach or failure to
perform constitutes self-dealing, willful misconduct or recklessness.

                  Section 14. (A) A Director of the Corporation shall stand in a
fiduciary relation to the Corporation and shall perform his or her duties as a
Director, including his or her duties as a member of any committee of the Board
upon which he or she may serve, in good faith, in a manner he or she 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:



                                      - 7 -





                  (1) One or more officers or employees of the Corporation whom
                  the Director reasonably believes to be reliable and competent
                  in the matters presented.

                  (2) Counsel, public accountants or other persons as to matters
                  which the Director reasonably believed to be within the
                  professional or expert competence of such person.

                  (3) A committee of the Board upon which he or she does not
                  serve, duly designated in accordance with law, as to matter
                  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 he or she has knowledge concerning the matter in question that would cause
his or her reliance to be unwarranted.

                  (B) In discharging the duties of their respective positions,
the Board of Directors, committees of the Board and individual Directors may, in
considering the best interest of the Corporation, consider the effects of any
action upon employees, upon suppliers and 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 A.

                  (C) 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 interest of the Corporation.

                  The standard of care recited herein shall comply with the
requirements of the Directors' Liability Act, 42 Pa. C.S.A. 8361, et seq., and
the Associations Code, 15 Pa.C.S.A. 1721, as the same may be amended from time
to time.

                  Section 15. The Corporation shall indemnify each person who
was or is a party or is 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 or she 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, partnership, joint venture,
trust, employee benefit plan or other enterprise, against expenses (including
attorneys' fees), judgments, fines and amounts paid in settlement actually and
reasonably incurred by him or her in connection with the action or proceeding if
he or she acted in good faith and in a manner he or she reasonably believed to
be in, or not opposed to, the best interest of the Corporation and, with respect
to any criminal proceeding, had no reasonable cause to believe his or her
conduct was unlawful. The termination of any action or proceeding by judgment,
order, settlement or conviction, or upon the plea of nolo contendere or its
equivalent shall not of itself create a presumption that the person did not act
in


                                      - 8 -





good faith and in a manner that he or she reasonably believed to be in, or not
opposed to, the best interest of the Corporation and, with respect to any
criminal proceeding, had reasonable cause to believe that his or her conduct was
unlawful.

                  Section 16. The 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 by or in the right of the Corporation to procure a judgment
in its favor by reason of the fact that he or she is or was a representative of
the Corporation 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, employee benefit plan or
other enterprise, against expenses (including attorneys, fees) actually and
reasonably incurred by him or her in connection with the defense or settlement
of the action if he or she acted in good faith and in a manner he or she
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.

                  Section 17. 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 15 and 16
above, or in defense of any claim, issue or matter therein, he or she shall be
indemnified against expenses (including attorney's fees) actually and reasonably
incurred by or imposed upon him or her in connection therewith.

                  Section 18. Unless ordered by a Court, any indemnification
under Sections 15 or 16 above shall be made by the Corporation only as
authorized in the specific case upon a determination that the indemnification of
the Director, officer, employee or agent is proper in the circumstances because
he or she has met the applicable standard of conduct set forth in those
sections. Such 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 quorum is not obtainable, or if obtainable and a
                  majority vote of a quorum of disinterested directors so
                  directs, by independent legal counsel in written opinion; or

                  (3)      By the shareholders.



                                      - 9 -





                  Section 19. Expenses (including attorneys' fees) incurred by a
Director, officer, employee or agent in defending any action or proceeding
referred to in Sections 15 or 16 above may be paid by the Corporation in advance
of the final disposition of the action or proceeding upon receipt of an
undertaking by or on behalf of the Director, officer, employee or agent to repay
the amount if it is ultimately determined that he or she is not entitled to be
indemnified by the Corporation as authorized in this Article.

                  Section 20. The indemnification and advancement of expenses
provided by, or granted pursuant to, this Article, 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 or her official
capacity and as to action in another capacity while holding that office.
Indemnification pursuant to this paragraph shall not be made in any case where
the act or failure to act giving rise to the claim from indemnification is
determined by a Court to have constituted willful misconduct or recklessness.

                  Section 21. No amendment or repeal of this Article shall
adversely affect any right or protection extended to a Director Officer,
employee or agent hereunder for an act or failure to act occurring prior to the
time of such amendment or repeal. Each Director, officer, employee and agent
shall be deemed to act in such capacity in reliance upon the rights of
indemnification and advancement of expenses hereunder 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 person.

                  Section 22. The 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. 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 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 or her and
incurred by him or her in any such capacity, or arising out of his or her status
as such, whether or not the Corporation would have the power to indemnify him or
her against such liability under the provisions of this article or otherwise.

                  Section 23. No contract or transaction between the Corporation
and one or more of its Directors or officers or between the Corporation and any
other corporation, partnership, association or other organization in which one
or more of its Directors or Officers are Directors or Officers or have a
financial interest, shall be void or voidable solely for such reason, or solely
because the Director or Officer is present at or participates in the meeting of
the Board of Directors which authorizes the contract or transaction, or solely
because his, her or their votes are counted for such purpose, if: (a) the
material facts as to the relationship or interest and as to the contract or
transaction are disclosed or are known to the Board of Directors and the Board
in


                                     - 10 -





good faith authorizes the contract or transaction by the affirmative votes of a
majority of the disinterested Directors even though the disinterested Directors
are less than a quorum; (b) the material facts as to his or her relationship or
interest and as to the contract or transaction are disclosed or are known to the
stockholders entitled to vote thereon, if any, and the contract or transaction
is specifically approved in good faith by vote of such Stockholders; or (c) the
contract or transaction is fair as to the Corporation as of the time it is
authorized, approved or ratified by the Board of Directors or the Stockholders.
Common or interested Directors may be counted in determining the presence of a
quorum at a meeting of the Board which authorizes a contract or transaction
specified above.

                  Section 24. Any payments made to an officer or employee of the
Corporation, such as salary, commission, bonus, interest or rent or
entertainment or travel expense, which shall be disallowed to the Corporation in
whole or in part as a deductible expense by the Internal Revenue Service shall
be reimbursed by such officer or employee to the Corporation to the full extent
of such disallowance. It shall be the duty of the Board of Directors, as a
Board, to enforce payment of each such amount disallowed.

                  Section 25. Anything set forth in these Bylaws to the contrary
notwithstanding, it is the intent that the indemnification provisions hereof
shall be to the full extent permitted by the Associations Code (effective
generally October 1, 1989), 15 Pa.C.S. ss.1741, et seq. To the extent that the
indemnification provisions set forth in these Bylaws does not go to the length
permitted by said Associations Code, said indemnification provisions are hereby
deemed to be incorporated by reference.

                             CERTIFICATES OF SHARES

                  Section 1. The certificate of shares of the Corporation shall
be numbered and registered in a share register of the Corporation as they are
issued. They shall exhibit the name of the registered holder and the number and
class of shares and the series, if any, represented thereby and the par value of
each share or a statement that such shares are without par value, as the case
may be.

                  Section 2. Every share certificate shall be signed by the
President or Vice-President and the Secretary or an Assistant Secretary or the
Treasurer or an Assistant Treasurer, but where such certificate is signed by a
transfer agent or by a transfer clerk of the Corporation and 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


                                     - 13 -





has been placed upon any share certificate shall have ceased to be such Officer
because of death, resignation, or otherwise, before such 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.

                  Section 3. Neither shares nor certificates representing such
shares may be issued by the Corporation until the full amount of the
consideration has been paid. The consideration for the issuance of the shares
may be paid, in whole or in part, in money, obligations (including an obligation
of a shareholder, services performed whether or not contracted for, contracts
for services to be performed or other tangible or intangible property). Neither
promissory notes nor future services shall constitute payment, or part payment,
for the shares of the Corporation.

                  Section 4. The Corporation may issue one (1) or more classes
or series of shares, or both, any of which classes or series may be with par
value or without par value, and with such other designations, preferences,
qualifications, privileges, limitations, options, conversion rights and such
other special or relative rights as are stated in the Articles of Incorporation
or resolution of the Board of Directors. All shares of any one class shall have
the same conversion, redemption and other rights, preferences, qualifications,
limitations and restrictions. If the Corporation is authorized to issue shares
of more than one class, the certificate shall set forth a full summary or
statement or designations, preferences, limitations and relative rights of the
shares of each class authorized to be issued.

                               TRANSFER OF SHARES

                  Section 5. Upon surrender to the Corporation or its transfer
agent of a share certificate duly endorsed or accompanied by proper evidence of
succession, assignment or authority to transfer, a new certificate shall be
issued to the person entitled thereto and the old certificate cancelled and the
transaction recorded upon the books of the Corporation.

                               FIXING RECORD DATE

                  Section 6. The Board of Directors may fix a time, not more
than one hundred twenty (120) days, prior to the date of any meeting of
shareholders or the date fixed for payment of any dividend or distribution or
the date for the allotment of rights or the date when any change or conversion
or exchange of shares will be made or go into effect, as a record date for the
determination of the shareholders entitled to notice of and to vote at any such
meeting or entitled to receive payment of any such dividend or distribution or
to receive any such allotment of rights or to exercise the rights in respect to
any such change, conversion or exchange of shares. In such case, only such
shareholders as shall be shareholders of record on the date so fixed shall be
entitled to notice of and to vote at such meeting or to receive payment of such
dividend or to receive such allotment or to exercise such rights, as the case
may be, notwithstanding any transfer of any shares on the books of the
Corporation after any record date so fixed. The Board of Directors may close the
books of the Corporation against transfer of shares during the whole or any part
of such period and in such case, written or printed notice shall be mailed at
least ten days


                                     - 14 -





before the closing thereof to each shareholder of record at the address
appearing on the records of the Corporation or supplied by him or her to the
Corporation for the purpose of this notice.

                             REGISTERED SHAREHOLDERS

                  Section 7. The Corporation shall be entitled to treat the
holder of record of any share or shares as the holders in fact thereof, and
accordingly, shall not be bound to recognize any equitable or other claim to or
interest in such share on the part of any other person, and shall not be liable
for any registration or transfer of shares which are registered or to be
registered in the name of the fiduciary or the nominee of a fiduciary unless
made with actual knowledge that a fiduciary or nominee of a fiduciary is
committing a breach of trust in requesting such registration or transfer, or
with knowledge of such facts that its participation therein amounts to bad
faith.

                                LOST CERTIFICATE

                  Section 8. The Board of Directors may direct a new certificate
or certificates to be issued in place of any certificate or certificates
theretofore issued by the Corporation alleged to have been lost or destroyed,
upon the making of an Affidavit of that fact by the person claiming the share
certificate to be lost or destroyed. When authorizing such issuance of a new
certificate or certificates, the Board of Directors may in its discretion and as
a condition precedent to the issuance thereof, require the owner of such lost or
destroyed certificate or certificates, or his or her legal representative, to
advertise the same in such manner as it shall require and/or give the
Corporation a bond in such sum as it may direct as indemnity against any claim
that may be made against the Corporation with respect to the certificate or
certificates alleged to have been lost or destroyed.

                                   ARTICLE VI

                               GENERAL PROVISIONS

                                      SEAL

                  Section 3. The corporate seal, if any, shall have inscribed
thereon the name of the Corporation, the year of its organization and the words
"Corporate Seal, Pennsylvania". Said seal may be used by causing it or a
facsimile thereof to be impressed or fixed or in any manner reproduced. The
affixation of the corporate seal shall not be necessary to the valid execution,
assignment or endorsement by the Corporation of any instrument or other
document.

                                     NOTICES

                  Section 4. Whenever written notice is required to be given to
any person under the provisions of these Bylaws, it may be given to the person
either personally or by sending a copy thereof by first class or express mail,
postage prepaid, or by telegram (with messenger service specified), telex or TWX
(with answer back received) or courier service, charges prepaid, or by
telecopier to his or her address (or to his or her telex), TWX, telecopier or
telephone number, appearing on the books of the Corporation or, in the case of
Directors, supplied by him or her to the Corporation for the purpose of notice,
if the notice is sent by mail, telegraph or courier service, it shall be deemed
to have been given to the person entitled thereto when deposited in the United
States mail or with a telegraph office or courier service for delivery to that
person or, in the case of telex or TWX, when dispatched.

                  Section 5. Any notice required to be given to any person may
be waived in writing signed by the person entitled to such notice whether before
or after the time stated therein. Attendance of any person entitled to notice,
either in person or by proxy, at any meeting shall constitute a waiver of notice
of such meeting, except where any person attends a meeting for the express
purpose of objecting to the transaction of any business because the meeting was
not lawfully called or convened.

                                CORPORATE RECORDS

                  Section 6. The Corporation shall keep complete and accurate
books and records of account, minutes of the proceedings of the incorporators,
shareholders and directors and a share register giving the names and addresses
of all shareholders and the number and class of shares held by each. The share
register shall be kept at either the registered office of the Corporation in
this Commonwealth or at its principal place of business wherever situated or at
the office of its registrar or transfer agent. Any books, minutes or other
records may be in written form or any other form capable of being converted into

                  Section 7. Every shareholder shall, upon written verified
demand stating the purpose thereof, have a right to examine, in person or by
agent or attorney, during the usual hours for business for any proper purpose,
the share register, books and records of account, and records of the proceedings
of the incorporators, shareholders and directors and to make copies or extracts
therefrom. A proper purpose shall mean a purpose reasonably related to the
interest of the person as a shareholder. In every instance where an attorney or
other agent is the person who seeks the right of inspection, the demand shall be
accompanied by a verified power of attorney or other writing that authorizes the
attorney or other agent to so act on behalf of the shareholder. The demand shall
be directed to the Corporation at its registered office in this Commonwealth or
at its principal place of business wherever situated.

                                   ARTICLE VII
