                         As amended through December 16, 1996

                                      ARTICLE I

                                     SHAREHOLDERS

    Section 1.1  Annual Meeting.  An annual meeting of the shareholders 
shall be held in each calendar year, on such date and at such time as may be 
fixed by the board of directors, for the purpose of electing directors and 
for the transaction of such other business as may properly come before the 
meeting.  If the day fixed for the annual meeting shall be a legal holiday in 
the state where the meeting is to be held, such meeting shall be held on the 
next succeeding business day.

    Section 1.2  Special Meetings.  Special meetings of the shareholders may 
be called at any time by (a) the board of directors or (b) by shareholders 
entitled to cast at least 20% of the votes that all shareholders are entitled 
to cast at the particular meeting.  Upon written request of any person who 
has duly called a special meeting, the secretary shall fix the time of the 
meeting which shall be held not more than 30 days after the receipt of the 
request.  If the secretary neglects or refuses to fix the time of the 
meeting, the person or persons duly calling the meeting may do so.

    Section 1.3  Place of Meeting.  All meetings of the share-holders shall 
be held at the registered office of the Corporation or at such other place, 
within or without the Commonwealth of Pennsylvania, as may be designated by 
the board of directors from time to time.

    Section 1.4  Notice.  Except as provided in Section 1.6 of the bylaws, 
written notice of every meeting of the shareholders shall be given by, or at 
the direction of, the secretary or other authorized person or, if he or she 
neglects or refuses to do so, 

                                  -1-


may be given by the person or persons calling the meeting, to each 
shareholder of record entitled to vote at the meeting, at least 10 days prior 
to the day named for a meeting called to consider a fundamental transaction 
under 15 Pa.C.S. Chapter 19 or at least 5 days prior to the day named for a 
meeting in all other cases, unless a greater period of notice is required by 
statute in the particular case.  The notice of meeting shall specify the 
place, day and hour of the meeting and, in the case of a special meeting, the 
general nature of the business to be transacted, and, if applicable, the 
notice shall state that the purpose, or one of the purposes, of the meeting 
is to consider the adoption, amendment or repeal of the bylaws in which case 
the notice shall include, or be accompanied by, a copy to be proposed 
amendment or a summary of the changes to be effected thereby.

    Section 1.5  Quorum.  A shareholders' meeting duly called shall not be 
organized for the transaction of business unless a quorum is present.  The 
presence in person or by proxy of shareholders entitled to cast at least a 
majority of the votes that all shareholders are entitled to cast on a 
particular matter to be acted upon at the meeting shall constitute a quorum 
for the purposes of consideration and action on such matter.  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.  If a meeting cannot be organized because a quorum 
has not attended, those present may adjourn the meeting to such time and 
place as they may determine.  Those shareholders entitled to vote who attend 
a meeting called for the election of directors that has previously been 
adjourned for lack of a quorum, although less than a quorum as fixed herein, 
shall nevertheless constitute a quorum for the purpose of electing directors. 
 In other cases, those shareholders entitled to vote who attend a meeting of 
shareholders that has been previously adjourned for one or more periods 
aggregating at least 15 days because of an absence of a quorum, although less 
than a quorum as fixed herein, shall nevertheless constitute a quorum for the 
purpose of acting upon any matter set forth in the notice of the meeting, 
provided that the notice of the meeting states that those shareholders who 
attend such adjourned meeting shall nevertheless constitute a quorum for the 
purpose of acting upon the matter set forth in the notice.

                                  -2-

 
    Section 1.6  Adjournments.  Adjournment or adjournments of any annual or 
special meeting of shareholders, other than one at which directors are to be 
elected, may be taken for such period or periods as the presiding officer of 
the meeting or the shareholders present in person or by proxy and entitled to 
vote shall direct.  A meeting at which directors are to be elected shall be 
adjourned only from day to day, or for such longer periods not exceeding 
fifteen days each as the shareholders present and entitled to vote shall 
direct, until the directors have been elected.  When a meeting of 
shareholders is adjourned, it shall not be necessary to give any notice of 
the adjourned meeting or of the business to be transacted at the adjourned 
meeting other than by announcement at the meeting at which the adjournment is 
taken, unless the board of directors fixes a new record date for the 
adjourned meeting.

    Section 1.7  Action by Shareholders.  Whenever any corporate action is to 
be taken by vote of the shareholders, it shall be authorized by a majority of 
the votes cast at a duly organized meeting of shareholders by the holders of 
shares entitled to vote thereon, except where a different vote is required by 
law or the articles or these bylaws.

    Section 1.8  Voting Rights of Shareholders.  Unless otherwise provided in 
the articles, every shareholder shall be entitled to one vote for every share 
outstanding in such shareholder's name on the books of the Corporation.

    Section 1.9  Proxies.  Every shareholder entitled to vote at a 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 such 
shareholder by proxy. The presence of or vote or other action at a meeting of 
shareholders, or the expression of consent or dissent to corporate action in 
writing by, a proxy of a shareholder shall constitute the presence of, or 
vote or action by, or written consent or dissent of the shareholder.

    Section 1.10  Voting List.  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 the number of shares held by 
each. The list shall be produced and kept open at the time and place of the 
meeting and 

                                  -3-


shall be subject to the inspection of any shareholder during the whole time 
of the meeting for the purposes thereof.  Failure to comply with the 
requirements of this bylaw shall not affect the validity of any action taken 
at a meeting prior to a demand at the meeting by any shareholder entitled to 
vote thereat to examine the list.

    Section 1.11  Determination of Shareholders of Record.

         (a)  The board of directors may fix a time prior to the date of any 
meeting of shareholders as a record date for the determination of the 
shareholders entitled to notice of, or to vote at, the meeting, which time, 
except in the case of an adjourned meeting, shall be not more than 45 days 
prior to the date of the meeting of shareholders.  Only shareholders of 
record on the date fixed shall be entitled to notice of, or to vote at, such 
meeting, notwithstanding any transfer of shares of the books of the 
Corporation after the record date so fixed.  The board of directors may 
similarly fix a record date for the determination of shareholders of record 
for payment of dividends or for any other purpose.  When a determination of 
shareholders of record has been made as provided in this bylaw for purposes 
of a meeting, the determination shall apply to any adjournment thereof unless 
the board fixes a new record date for the adjourned meeting.

         (b)  If a record date is not fixed:

              (i)    The record date for determining shareholders entitled to 
notice of or to vote at a meeting of shareholders shall be the close of 
business on the day next preceding the day on which notice is given or, if 
notice is waived, at the close of business on the day immediately preceding 
the day on which the meeting is held.

              (ii)   The record date for determining shareholders entitled to 
express consent or dissent to corporate action in writing without a meeting, 
when prior action by the board of directors is not necessary, shall be the 
close of business on the day on which the first written consent or dissent is 
filed with the secretary of the Corporation.

              (iii)  The record date for determining shareholders for any 
other purpose shall be at the close of business on the day 

                                  -4-


on which the board of directors adopts the resolution relating thereto.

    Section 1.12  Presiding Officer.  All meetings of the shareholders shall 
be called to order and presided over by the chairperson of the board of 
directors, if any, if there is no chairperson or in the chairperson's 
absence, by the president, or, in the absence of the president, by a 
chairperson of the meeting elected by the shareholders.

    Section 1.13  Election of Directors. In elections for direc-tors, voting 
need not be by ballot, except upon demand made by a shareholder entitled to 
vote at the election and before the voting begins.  The candidates receiving 
the highest number of votes from each class or group of classes, if any, 
entitled to elect directors separately up to the number of directors to be 
elected by the class or group of classes shall be elected.  If at any meeting 
of shareholders, directors of more than one class are to be elected, each 
class of directors shall be elected in a separate election. In each election 
of directors every shareholder entitled to vote shall have the right to 
multiply the number of votes to which such shareholder is entitled by the 
number of directors to be elected in the same election by the holders of the 
class or classes of shares of which his or her shares are a part and he or 
she may cast the whole number of votes thus obtained for one candidate or 
distribute them among any two or more candidates.

    Section 1.14  Judges Of Election.  In advance of any meeting of 
shareholders, the board of directors may appoint judges of election, who need 
not be shareholders, to act at such meeting or any adjournment thereof.  If 
judges of election are not so appointed, the presiding officer of any such 
meeting may, and on the request of any shareholder shall, make such 
appointment at the meeting.  The number of judges shall be one or three. No 
person who is a candidate for office to be filled at the meeting shall act as 
a judge.  In case any person appointed as a judge fails to appear or fails or 
refuses to act, the vacancy may be filled by appointment made by the board of 
directors in advance of the convening of the meeting or at the meeting by the 
presiding officer thereof.  The judge or judges of election shall determine 
the number of shares outstanding and the voting power of each, the shares
represented at the meeting, the existence of a quorum, and the authenticity,
validity and effect of proxies, shall receive 

                                  -5-


votes or ballots, shall hear and determine all challenges and questions in 
any way arising in connection with the right to vote, shall count and 
tabulate all votes and determine the result and shall do such acts as may be 
proper to conduct the election or vote with fairness to all shareholders.  
The judge or judges of election shall perform their duties impartially, in 
good faith, to the best of their ability, and as expeditiously as is 
practical.  If there are three judges of election, the decision, act or 
certificate of a majority shall be effective in all respects as the decision, 
act or certificate of all.  On request of the presiding officer of the 
meeting, or of any shareholder, the judge or judges shall make a report in 
writing of any challenge or question or matter determined by them and execute 
a certificate of any fact found by them.  Any report or certificate made by 
them shall be prima facie evidence of the facts stated therein.

                                      ARTICLE II

                                  BOARD OF DIRECTORS

    Section 2.1  General.  All powers vested by law in the Corpor-ation 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.

    Section 2.2  Number, Qualifications, Term of Office. The board of 
directors of the Corporation shall consist of at least one and not more than 
seven* directors, the exact number to be set from time to time by resolution 
of the board of directors of the Corporation.  Each director shall be a 
natural person of full age but need not be a resident of Pennsylvania or a 
shareholder of the Corporation.  Each director shall hold office until the 
expiration of the term for which he or she was selected and until said 
director's successor has been selected and qualified or until said director's 
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.

the shareholders except as provided in Section 2.4 hereof.

                                  -6-

    Section 2.4  Vacancies.  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 a sole remaining director, and each person so selected 
shall be a director to serve for the balance of the unexpired term and until 
his or her successor has been selected and qualified or until his or her 
earlier death, resignation or removal.

    Section 2.5  Removal and Resignation.

         (a)  Removal by action of shareholders.  The entire board of 
directors or any individual director may be removed from office without 
assigning any cause by the vote of shareholders entitled to elect directors 
provided, however, that an individual director shall not be removed (unless 
the entire board is removed) if sufficient votes are cast against the 
resolution for his or her removal, if cumulatively voted at an annual meeting 
or other election of directors, would be sufficient to elect one or more 
directors to the board.  In case the board or any one or more directors are 
so removed, new directors may be elected at the same meeting.

         (b)  Removal by action of the directors.  The board of directors may 
declare vacant the office of a director if said director: (i) has been 
judicially declared of unsound mind; (ii) has been convicted of an offense 
punishable by imprisonment for a term of more than one year; or (iii) if 
within 60 days after notice of his or her election, said director does not 
accept such office either in writing or by attending a meeting of the board 
of directors and fulfilling such other requirements of qualification as these 
bylaws or the articles may provide.

         (c)  Resignation.  Any director may resign at any time from his or 
her position as a director of the Corporation upon written notice to the 
Corporation.  The resignation shall be effective upon receipt thereof by the 
Corporation or at such subsequent time as may be specified in the notice of 
resignation.

    Section 2.6  Regular Meetings.  The board of directors shall hold an 
annual meeting for the election of officers and the transaction of other 
proper business either as soon as practical after, and at the same place as, 
the annual meeting of shareholders 

                                  -7-


or at such other day, hour and place as may be fixed by the board.  The board 
of directors may designate by resolution the day, hour and place, within or 
without the Commonwealth of Pennsylvania, of other regular meetings.

    Section 2.7  Special Meetings.  Special meetings of the board may be 
called by the chairperson of the board, if any, the president or any two 
directors. The person or persons calling the special meeting may fix the day, 
hour and place, within or without the Commonwealth of Pennsylvania, of the 
meeting.

    Section 2.8  Notice of Meetings.  No notice of any annual or regular 
meeting of the board of directors need be given.  Written notice of each 
special meeting of the board of directors, specifying the place, day and hour 
of the meeting, shall be given to each director at least 48 hours before the 
time set for the meeting.  Neither the business to be transacted at, nor the 
purpose of, any annual, regular or special meeting of the board need be 
specified in the notice of the meeting.

    Section 2.9  Quorum of and Action by Directors.  A majority of the 
directors in office shall constitute a quorum for the transaction of 
business, and the acts of a majority of directors present and voting at a 
meeting at which a quorum is present shall be the acts of the board of 
directors except where a different vote is required by law or the articles or 
these bylaws.  Every director shall be entitled to one vote.  There shall be 
voting by proxy.

    Section 2.10  Interested Directors or Officers; Quorum. A con-tract or 
transaction between the Corporation and one or more of its directors or 
officers, or between the Corporation and any other domestic or foreign 
corporation for profit or not-for-profit, partnership, joint venture, trust 
or other enterprise in which one or more of this Corporation's directors or 
officers are directors or officers or have a financial or other interest, 
shall not be void or voidable solely for that reason, or solely because the 
common or interested director or officer is present at or participates in the 
meeting of the board that authorizes the contract or transaction, or solely 
because the common or interested director's or officer's vote is 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 authorizes the contract or transaction by 

                                  -8-


the affirmative vote of a majority of the disinterested directors even though 
the disinterested directors are less than a quorum; or (b) the material facts 
as to the director's or officer's relationship or interest and as to the 
contract or transaction are disclosed or are known to the shareholders 
entitled to vote thereon, and the contract or transaction is specifically 
approved in good faith by vote of those shareholders; or (c) the contract or 
transaction is fair as to this Corporation as of the time it is authorized, 
approved or ratified by the board of directors or the shareholders.  Common 
or interested directors may be counted in determining the presence of a 
quorum at a meeting of the board of directors which authorizes a contract or 
transaction specified in this Section 2.10.

    Section 2.11  Compensation.  By resolution of the board of directors, 
each director may be paid his or her expenses, if any, of attendance at each 
meeting of the board of directors or committee thereof, and may be paid a 
stated salary as director or a fixed sum for attendance at each meeting of 
the board of directors or committee thereof or both.  No such payment shall 
preclude any director from serving the Corporation in any other capacity and 
receiving compensation therefor and a director may be a salaried officer or 
employee of the Corporation.

    Section 2.12  Presumption of Assent.  A director of the Corp-oration 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 such director files his or her 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.  Such 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 a 
meeting incorrectly omitted said director's dissent if, promptly upon receipt 
of a copy of such minutes, said director notifies the secretary, in writing, 
of the asserted omission or inaccuracy.

    Section 2.13  Presiding Officer.  All meetings of the board of directors 
shall be called to order and presided over by the chairperson of the board of 
directors, if any, or, if there is no 

                                  -9-


chairperson or in the chairperson's absence, by the president or, in the 
absence of the chairperson and president, by a chairperson of the meeting 
elected at such meeting by the board of directors.

    Section 3.1  Committees of the Board.  The board of directors may, by 
resolution adopted by a majority of the directors in office, establish one or 
more committees, each committee to consist of one or more of the directors of 
the Corporation. The board may designate one or more directors as alternate 
members of any committee who may replace any absent or disqualified member at 
any meeting of the committee or for purposes of any written action of the 
committee.  A committee, to the extent provided in the resolution of the 
board of directors creating it, shall have and may exercise all of the powers 
and authority of the board of directors except that a committee shall not 
have any power or authority as to:  (a) the submission to shareholders of any 
action requiring the approval of shareholders pursuant to the Business 
Corporation Law, as it may hereafter be amended, (b) the creation or filling 
of vacancies in the board of directors, (c) the adoption, amendment or repeal 
of the bylaws, (d) the amendment, adoption or repeal of any resolution of the 
board that by its terms is amendable or repealable only by the board, or (e) 
action on matters committed by the bylaws or resolution of the board to 
another committee of the board. Each committee of the board shall serve at 
the pleasure of the board.

    Section 3.2  Committee Rules.  Unless the board of directors provides 
otherwise by resolution each committee shall conduct its business and take 
action in the same manner as the board conducts its business pursuant to the 
articles of the Corporation and these bylaws.

elect a chairperson of the board of directors, one or more vice presidents, 
and such other officers and assistant officers as the board deems necessary 
or advisable.  All officers shall be natural persons of full age.  Any two or 
more offices may be held by the same person.  It shall not be necessary for 
officers to be directors of the Corporation.  Officers of the Corporation, as 
between themselves and the Corporation, shall have such authority and perform 
such duties in the management of the Corporation as is provided by or

removed by the board of directors with or without cause, but such removal

removed. Election or appointment of an officer or agent shall not of itself 
create contract rights.

notice to the Corporation.  The resignation shall be effective upon receipt 
thereof by the Corporation or at such subsequent time as may be specified in

compensation of each of the officers elected by the board shall be fixed from 
time to time by the board of directors and the salaries of all other officers

other person as may be designated from time to time by the president or the 
board.

and class of shares and the designation of the series, if any, which the

                                  -13-


         Every share certificate shall be executed by facsimile or otherwise,

of the Corporation as the owner thereof for all purposes.

    Section 5.3  Lost, Destroyed or Stolen Certificates.  If the registered 
owner of a share certificate claims that the security has been lost,

manner and upon such terms as the board of directors may authorize and shall 
be issued in place of the original security, in accordance with 13 Pa.C.S. 
Section 8405(2), if the owner: (a) so requests before the Corporation has

                                      ARTICLE VI

                      MANNER OF GIVING NOTICE, WAIVER OF NOTICE,
                   ACTION WITHOUT MEETING, BY CONFERENCE TELEPHONE
                            AND MODIFICATION OF PROPOSALS

    Section 6.1  Manner of Giving Notice.  Whenever written notice is 
required to be given to any person under the provisions of the Business 
Corporation Law, as it may hereafter be amended, or by the articles or 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 courier service, 
charges prepaid, or by telecopier, to the shareholder's address (or to the 
shareholder's telecopier number) appearing on the books of the Corporation 
or, in the case of directors, supplied by the director to the Corporation for 
the purpose of notice.  Notice sent by mail, or by courier service shall be 
deemed to have been given when deposited in the United States mail or with a 
courier service for delivery, except 

                                  -14-


that, in the case of directors, notice sent by regular mail shall be deemed 
to have been given 48 hours after being deposited in the United States mail 
or, in the case of telecopier, when dispatched.

    Section 6.2  Waiver of Notice.  Whenever any written notice is required 
to be given by statute or the articles or these bylaws, a waiver thereof in 
writing, signed by the person or persons entitled to the notice, whether 
before or after the time stated therein, shall be deemed equivalent to the 
giving of the notice.  Neither the business to be transacted at, nor the 
purpose of, a meeting need be specified in the waiver of notice of such 
meeting, except that, in the case of a special meeting of shareholders, the 
general nature of the business to be transacted at the meeting shall be so 
specified in the waiver of notice thereof.  Attendance of a person, either in 
person or by proxy, at any meeting shall constitute a waiver of notice of the 
meeting, except where the person attends the meeting for the express purpose 
of objecting, at the beginning of the meeting, to the transaction of any 
business because the meeting was not lawfully called or convened.

    Section 6.3  Action by Unanimous Written Consent.  Any action required or 
permitted to be taken at a meeting of the shareholders, of a class of 
shareholders, or the directors, or of a committee of directors may be taken 
without a meeting if, prior or subsequent to the action, a consent or 
consents thereto in writing setting forth the action so taken is signed by 
all the shareholders who would be entitled to vote at a meeting for such 
purpose, or by all of the directors in office, or by all of the members of 
such committee in office, as the case may be, and is filed with the secretary 
of the Corporation.

    Section 6.4  Shareholder Action by Partial Written Consent.  Any action 
required or permitted to be taken at a meeting of the shareholders or of a 
class of shareholders may be taken without a meeting upon the written consent 
of shareholders who would have been entitled to cast the minimum number of 
votes that would be necessary to authorize the action at a meeting at which 
all shareholders entitled to vote thereon were present and voting.  The 
consents shall be filed with the secretary of the Corporation.  The action 
shall not become effective until after at least 10 days' written notice of 
the action has been given to each shareholder entitled to vote thereon who 
has not consented thereto.

                                  -15-


    Section 6.5  Meetings by Means of Conference Telephone. One or more 
persons may participate in a meeting of the shareholders, of the directors, 
or of any committee of directors, by means of conference telephone or similar 
communications equipment by means of which all persons participating in the 
meeting can hear each other.  Such participation shall constitute presence in 
person at the meeting.

    Section 6.6  Modifications of Proposals.  Whenever the lang-uage of a 
proposed resolution is included in a written notice of a meeting required to 
be given by statute or by the articles or these bylaws, the meeting 
considering the resolution may without further notice adopt it with such 
clarifying or other amendments as do not enlarge its original purpose.

                              CERTAIN SHAREHOLDER RIGHTS

    Section 7.1  Financial Reports to Shareholders.  Unless other-wise agreed 
between this Corporation and a shareholder, the Corporation shall furnish to 
its shareholders annual financial statements, including at least a balance 
sheet as of the end of each fiscal year and a statement of income and 
expenses for the fiscal year.  The financial statements shall be prepared on 
the basis of generally accepted accounting principles, if the Corporation 
prepares financial statements for the fiscal year on that basis for any 
purpose, and may be consolidated statements of the Corporation and one or 
more of its subsidiaries. The financial statements shall be mailed by the 
Corporation to each of its shareholders entitled thereto within 120 days 
after the close of each fiscal year and, after the mailing and upon written 
request, shall be mailed by the Corporation to any shareholder or beneficial 
owner entitled thereto to whom a copy of the most recent annual financial 
statements has not previously been mailed. Statements that are audited or 
reviewed by a public accountant shall be accompanied by the report of the 
accountant; otherwise, each copy shall be accompanied by a statement of the 
person in charge of the financial records of the Corporation:

         (a)  Stating his reasonable belief as to whether or not the 
financial statements were prepared in accordance with generally 

                                  -16-


accepted accounting principles and, if not, describing the basis of 
presentation; and 

         (b)  Describing any material respects in which the financial 
statements were not prepared on a basis consistent with those prepared for 
the previous year.

    Section 7.2  Inspection of Corporate Records.  Every share-holder 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 Pennsylvania or at 
its principal place of business wherever situated.

    Section 7.3  Principles of Neutrality.*  Each shareholder of the 
Corporation acknowledges the importance of an open and unbiased marketplace 
of ideas in an environment of neutrality, and except as may be specified by a 
customer with respect to its own records, the search, retrieval and 
presentation of information by the Corporation shall be conducted in 
accordance with unbiased technical and quality considerations.  Further, to 
the extent economically feasible, the Corporation shall select participating 
publishers based on neutral technical and quality considerations, and neither 
the unpopularity of a publisher's ideas or the competition among publishers 
shall be grounds to discriminate against a publisher's participation.  The 
Corporation shall provide at a reduced or no charge to the end-user, a 
portion of its products and services to those who are worthy but needy, and 
when valued at the market price thereof, two percent of the Corporation's 
pre-tax income will be so allocated. The Corporation will strive to protect 
the privacy of its customers and except as permitted by the customer, shall 
not divulge to unauthorized parties his/her identity or any searches, 
retrievals or other transactions performed by or for the customer.  The 
Corporation 

                                  -17-

* Added by Amendment 1/7/93



shall establish procedures to assure compliance with the principles in this 
Section 7.3, and each shareholder shall be entitled to information concerning 
such compliance upon reasonable request for a proper purpose.  Nothing in 
this Section 7.3 shall create any third party beneficiary rights in any 
person or entity other than a shareholder of the Corporation. Notwithstanding 
any provision of these by-laws to the contrary, this Section 7.3 may be 
amended, repealed, replaced or waived only upon the affirmative vote of the 
holders of at least two-thirds of the shares of the Corporation entitled to 
vote thereon.


                                     ARTICLE VIII

                 NO PERSONAL LIABILITY; INDEMNIFICATION AND INSURANCE

    Section 8.1  No Personal Liability of Directors.  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 the director has 
breached or failed to perform the duties of his or her office under 15 Pa. 
C.S. Section 511 and Section 1721 and such breach or failure to perform 
constitutes self-dealing, willful misconduct or recklessness; provided, 
however, that the foregoing provision shall not eliminate or limit (a) the 
responsibility or liability of such director pursuant to any criminal 
statute, or (b) the liability of a director for the payment of taxes pursuant 
to local, state or Federal law.  Any repeal, modification or adoption of any 
provision inconsistent with Section 8.1 shall be prospective only, and 
neither the repeal or modification of this bylaw nor the adoption of any 
provision inconsistent with this bylaw shall adversely affect any limitation 
on the personal liability of a director of the Corporation existing at the 
time of such repeal or modification or the adoption of such inconsistent 
provision.

    Section 8.2  Mandatory Indemnification of Directors and Certain Other 
Persons. 
         
         (a) The Corporation shall indemnify and hold harmless to the full 
extent not prohibited by law, as the same exists or may hereinafter be 
amended, interpreted or implemented (but, in the case of any amendment, only 
to the extent that such amendment permits the Corporation to provide broader 
indemnification rights than are permitted the Corporation to provide prior to 
such 

                                  -18-


amendment), each person who was or is made a party or is threatened to be 
made a party to or is otherwise involved in (as a witness or otherwise) any 
threatened, pending or completed action, suit, or proceeding, whether civil, 
criminal, administrative or investigative and whether or not by or in the 
right of the Corporation or otherwise, (hereinafter, a "proceeding") by 
reason of the fact that he or she, or a person of whom he or she is the heir, 
executor, or administrator, is or was a director or officer of the 
Corporation or is or was serving at the request of the Corporation as a 
director, officer or trustee of another corporation or of a partnership, 
joint venture, trust or other enterprise (including without limitation 
service with respect to employee benefit plans), or where the basis of such 
proceeding is any alleged action or failure to take any action by such person 
while acting in an official capacity as a director or officer of the 
Corporation, or in any other capacity on behalf of the Corporation while such 
person is or was serving as a director or officer of the Corporation, against 
all expenses, liability and loss, including but not limited to attorneys' 
fees, judgments, fines, ERISA excise taxes or penalties and amounts paid or 
to be paid in settlement (whether with or without court approval), actually 
and reasonably incurred or paid by such person in connection therewith.

         (b)  Notwithstanding the foregoing, except as provided in Section 
8.3 below, the Corporation shall indemnify any such person seeking 
indemnification in connection with a proceeding (or part thereof) initiated 
by such person only if such proceeding (or part thereof) was authorized by 
the board of directors of the Corporation.

         (c)  Subject to the limitation set forth above concerning 
proceedings initiated by the person seeking indemnification, the right to 
indemnification conferred in this Section 8.2 shall be a contract right and 
shall include the right to be paid by the Corporation the expenses incurred 
in defending any such proceeding (or part thereof) or in enforcing his or her 
rights under this Section 8.2 in advance of the final disposition thereof 
promptly after receipt by the Corporation of a request therefor stating in 
reasonable detail the expenses incurred; provided, however, that to the 
extent required by law, the payment of such expenses incurred by a director 
or officer of the Corporation in advance of the final disposition of a 
proceeding shall be made only upon receipt of an 

                                  -19-


undertaking, by or on behalf of such person, to repay all amounts so advanced 
if and to the extent it shall ultimately be determined by a court that he or 
she is not entitled to be indemnified by the Corporation under this Section 
8.2 or otherwise.

         (d)  The right to indemnification and advancement of expenses 
provided herein shall continue as to a person who has ceased to be a director 
or officer of the Corporation or to serve in any of the other capacities 
described herein, and shall inure to the benefit of the heirs, executors and 
administrators of such person.

    Section 8.3  Payment of Indemnification.  If a claim for  
indemnification under Section 8.2 hereof is not paid in full by the Corporation 
within 30 days after a written claim therefor has been received by the 
Corporation, the claimant may, at any time thereafter, bring suit against the 
Corporation to recover the unpaid amount of the claim and, if successful in 
whole or in part on the merits or otherwise in establishing his or her right 
to indemnification or to the advancement of expenses, the claimant shall be 
entitled to be paid also the expense of prosecuting such claim.

    Section 8.4  Non-Exclusivity of Rights.  The right to indemnification 
and the payment of expenses incurred in defending a proceeding in advance of 
a final disposition conferred in Section 8.2 and the right to payment of 
expenses conferred in Section 8.3 shall not be deemed exclusive of any other 
rights to which those seeking indemnification or advancement of expenses 
hereunder may be entitled under any bylaw, agreement, vote of shareholders, 
vote of directors or otherwise, both as to actions in his or her official 
capacity and as to actions in any other capacity while holding that office, 
the Corporation having the express authority to enter into such agreements or 
arrangements as the board of directors deems appropriate for the 
indemnification of and advancement of expenses to present or future directors 
and officers as well as employees, representatives or agents of the 
Corporation in connection with their status with or services to or on behalf 
of the Corporation or any other corporation, partnership, joint venture, 
trust or other enterprise, including any employee benefit plan, for which 
such person is serving at the request of the Corporation.

                                  -20-

 
    Section 8.5  Funding.  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, including its 
obligation to advance expenses, whether arising under or pursuant to this 
Article VIII or otherwise.

    Section 8.6  Insurance.  The Corporation may purchase and maintain 
insurance on behalf of any person who is or was a director or officer or 
representative of the Corporation, or is or was serving at the request of the 
Corporation as a representative of another corporation, partnership, joint 
venture, trust or other enterprise, against any liability asserted against 
such person and incurred by such person in any such capacity, or arising out 
of his or her status as such, whether or not the Corporation has the power to 
indemnify such person against such liability under the laws of this or any 
other state.

    Section 8.7  Modification or Repeal.  Neither the modification, 
amendment, alteration or repeal of this Article VIII or any of its provisions 
nor the adoption of any provision inconsistent with this Article VIII or any 
of its provisions shall adversely affect the rights of any person to 
indemnification and advancement of expenses existing at the time of such 
modification, amendment, alteration or repeal or the adoption of such 
inconsistent provision.


                                      ARTICLE IX

begin on the 1st day of January in each year.

    Section 9.5  Amendment of Bylaws.  These bylaws may be amended or

the bylaw being amended or repealed, except where the power to repeal, adopt 
or amend a bylaw on any subject is expressly committed to the shareholders by 
the Business Corporation Law, as it may hereafter be amended, and subject 
always to the power of the shareholders to change any action taken by the 
board.  Any change in the bylaws shall take effect when adopted unless 
otherwise provided in the resolution effecting the change.
