                         As Adopted February 18, 1999

                                 STOCKHOLDERS
                                          
       SECTION 1.1:  ANNUAL MEETINGS.  An annual meeting of stockholders 
shall be held for the election of directors at such date, time and place, 
either within or without the State of Delaware, as the Board of Directors 
shall each year fix.  Any other proper business may be transacted at the 
annual meeting.

       SECTION 1.2:  SPECIAL MEETINGS.  Special meetings of stockholders for 
any purpose or purposes may be called at any time by the Board of Directors, 
and shall be called upon the request of the Chairperson of the Board of 
Directors, the Chief Executive Officer, the President or by a majority of the 
members of the Board of Directors.  Special meetings may not be called by any 
other person or persons.  If a special meeting of stockholders is called at 
the request of any person or persons OTHER THAN by a majority of the members 
of the Board of Directors, then such person or persons shall request such 
meeting by delivering a written request to call such meeting to each member 
of the Board of Directors, and the Board of Directors shall then determine 
the time, date and place of such special meeting, which shall be held not 
more than one hundred twenty (120) nor less than thirty-five (35) days after 
the written request to call such special meeting was delivered to each member 
of the Board of Directors.

       SECTION 1.3:  NOTICE OF MEETINGS.  Written notice of all meetings of 
stockholders shall be given stating the place, date and time of the meeting 
and, in the case of a special meeting, the purpose or purposes for which the 
meeting is called.  Unless otherwise required by applicable law or the 
Certificate of Incorporation of the Corporation, such notice shall be given 
not less than ten (10) nor more than sixty (60) days before the date of the 
meeting to each stockholder of record entitled to vote at such meeting.

       SECTION 1.4:  ADJOURNMENTS.  Any meeting of stockholders may adjourn 
from time to time to reconvene at the same or another place, and notice need 
not be given of any such adjourned meeting if the time, date and place 
thereof are announced at the meeting at which the adjournment is taken; 
PROVIDED, HOWEVER, that if the adjournment is for more than thirty (30) days, 
or if after the adjournment a new record date is fixed for the adjourned 
meeting, then a notice of the adjourned meeting shall be given to each 
stockholder of record entitled to vote at 



the meeting.  At the adjourned meeting the Corporation may transact any 
business that might have been transacted at the original meeting.

       SECTION 1.5:  QUORUM.  At each meeting of stockholders the holders of 
a majority of the shares of stock entitled to vote at the meeting, present in 
person or represented by proxy, shall constitute a quorum for the transaction 
of business, except if otherwise required by applicable law.  If a quorum 
shall fail to attend any meeting, the chairperson of the meeting or the 
holders of a majority of the shares entitled to vote who are present, in 
person or by proxy, at the meeting may adjourn the meeting.  Shares of the 
Corporation's stock belonging to the Corporation (or to another corporation, 
if a majority of the shares entitled to vote in the election of directors of 
such other corporation are held, directly or indirectly, by the Corporation), 
shall neither be entitled to vote nor be counted for quorum purposes; 
PROVIDED, HOWEVER, that the foregoing shall not limit the right of the 
Corporation or any other corporation to vote any shares of the Corporation's 
stock held by it in a fiduciary capacity. 

       SECTION 1.6:  ORGANIZATION.  Meetings of stockholders shall be 
presided over by such person as the Board of Directors may designate, or, in 
the absence of such a person, the Chairperson of the Board of Directors, or, 
in the absence of such person, the President of the Corporation, or, in the 
absence of such person, such person as may be chosen by the holders of a 
majority of the shares entitled to vote who are present, in person or by 
proxy, at the meeting.  Such person shall be chairperson of the meeting and, 
subject to Section 1.11 hereof, shall determine the order of business and the 
procedure at the meeting, including such regulation of the manner of voting 
and the conduct of discussion as seems to him or her to be in order.  The 
Secretary of the Corporation shall act as secretary of the meeting, but in 
such person's absence the chairperson of the meeting may appoint any person 
to act as secretary of the meeting.

       SECTION 1.7:  VOTING; PROXIES.  Unless otherwise provided by law or 
the Certificate of Incorporation, and subject to the provisions of Section 
1.8 of these Bylaws, each stockholder shall be entitled to one (1) vote for 
each share of stock held by such stockholder.  Each stockholder entitled to 
vote at a meeting of stockholders, or to express consent or dissent to 
corporate action in writing without a meeting, may authorize another person 
or persons to act for such stockholder by proxy.  Such a proxy may be 
prepared, transmitted and delivered in any manner permitted by applicable 
law.  Voting at meetings of stockholders need not be by written ballot unless 
such is demanded at the meeting before voting begins by a stockholder or 
stockholders holding shares representing at least one percent (1%) of the 
votes entitled to vote at such meeting, or by such stockholder's or 
stockholders' proxy; PROVIDED, HOWEVER, that an election of directors shall 
be by written ballot if demand is so made by any stockholder at the meeting 
before voting begins.  If a vote is to be taken by written ballot, then each 
such ballot shall state the name of the stockholder or proxy voting and such 
other information as the chairperson of the meeting deems appropriate.  
Directors shall be elected by a plurality of the votes of the shares present 
in person or represented by proxy at the meeting and entitled to vote on the 
election of directors.  Unless otherwise provided by applicable law, the 
Certificate of Incorporation or these Bylaws, every matter other than the 
election of directors shall be decided by the affirmative vote of the holders 
of a majority of the shares of stock entitled to vote thereon 

                                      -2-


that are present in person or represented by proxy at the meeting and are 
voted for or against the matter.  

       SECTION 1.8:  FIXING DATE FOR DETERMINATION OF STOCKHOLDERS OF RECORD. 
In order that the Corporation may determine the stockholders entitled to 
notice of or to vote at any meeting of stockholders or any adjournment 
thereof, or to express consent to corporate action in writing without a 
meeting, or entitled to receive payment of any dividend or other distribution 
or allotment of any rights, or entitled to exercise any rights in respect of 
any change, conversion or exchange of stock or for the purpose of any other 
lawful action, the Board of Directors may fix, in advance, a record date, 
which shall not precede the date upon which the resolution fixing the record 
date is adopted by the Board of Directors and which shall not be more than 
sixty (60) nor less than ten (10) days before the date of such meeting, nor 
more than sixty (60) days prior to any other action.  If no record date is 
fixed by the Board of Directors, then the record date shall be as provided by 
applicable law.  A determination of stockholders of record entitled to notice 
of or to vote at a meeting of stockholders shall apply to any adjournment of 
the meeting; PROVIDED, HOWEVER, that the Board of Directors may fix a new 
record date for the adjourned meeting.

       SECTION 1.9:  LIST OF STOCKHOLDERS ENTITLED TO VOTE.  A complete list 
of stockholders entitled to vote at any meeting of stockholders, arranged in 
alphabetical order and showing the address of each stockholder and the number 
of shares registered in the name of each stockholder, shall be open to the 
examination of any stockholder, for any purpose germane to the meeting, 
during ordinary business hours, for a period of at least ten (10) days prior 
to the meeting, either at a place within the city where the meeting is to be 
held, which place shall be specified in the notice of the meeting, or, if not 
so specified, at the place where the meeting is to be held.  The list shall 
also be produced and kept at the time and place of the meeting during the 
whole time thereof and may be inspected by any stockholder who is present at 
the meeting.

       SECTION 1.10: ACTION BY WRITTEN CONSENT OF STOCKHOLDERS. 

       (a)    PROCEDURE.  Unless otherwise provided by the Certificate of 
Incorporation, any action required or permitted to be taken at any annual or 
special meeting of the stockholders may be taken without a meeting, without 
prior notice and without a vote, if a consent or consents in writing, setting 
forth the action so taken, shall be signed by the holders of outstanding 
stock having not less than the number of votes that would be necessary to 
authorize or take such action at a meeting at which all shares entitled to 
vote thereon were present and voted.  Written stockholder consents shall bear 
the date of signature of each stockholder who signs the consent and shall be 
delivered to the Corporation by delivery to its registered office in the 
State of Delaware, to its principal place of business or to any officer or 
agent of the Corporation having custody of the book in which proceedings of 
meetings of stockholders are recorded.  Delivery made to the Corporation's 
registered office shall be by hand or by certified or registered mail, return 
receipt requested.  No written consent shall be effective to take the action 
set forth therein unless, within sixty (60) days of the earliest dated 
consent delivered to the Corporation in the manner provided above, written 
consents signed by a sufficient number of stockholders to take the action set 
forth therein are delivered to the Corporation in the manner provided above.

                                      -3-


       (b)    NOTICE OF CONSENT.  Prompt notice of the taking of corporate 
action by stockholders without a meeting by less than unanimous written 
consent of the stockholders shall be given to those stockholders who have not 
consented thereto in writing and who, if the action had been taken at a 
meeting, would have been entitled to notice of the meeting if the record date 
for such meeting had been the date that written consents signed by a 
sufficient number of holders to take the action were delivered to the 
Corporation.  In the case of a Certificate Action (as defined below), if the 
Delaware General Corporation Law so requires, such notice shall be given 
prior to filing of the certificate in question.  If the action which is 
consented to requires the filing of a certificate under the Delaware General 
Corporation Law (a "CERTIFICATE ACTION"), then if the Delaware General 
Corporation Law so requires, the certificate so filed shall state that 
written stockholder consent has been given in accordance with Section 228 of 
the Delaware General Corporation Law and that written notice of the taking of 
corporate action by stockholders without a meeting as described herein has 
been given as provided in such section.

       SECTION 1.11: INSPECTORS OF ELECTIONS.

       (a)    APPLICABILITY.  Unless otherwise provided in the Corporation's 
Certificate of Incorporation or required by the Delaware General Corporation 
Law, the following provisions of this Section 1.11 shall apply only if and 
when the Corporation has a class of voting stock that is:  (i) listed on a 
national securities exchange; (ii) authorized for quotation on an automated 
interdealer quotation system of a registered national securities association; 
or (iii) held of record by more than 2,000 stockholders; in all other cases, 
observance of the provisions of this Section 1.11 shall be optional, and at 
the discretion of the Corporation.  

       (b)    APPOINTMENT.  The Corporation shall, in advance of any meeting 
of stockholders, appoint one or more inspectors of election to act at the 
meeting and make a written report thereof.  The Corporation may designate one 
or more persons as alternate inspectors to replace any inspector who fails to 
act.  If no inspector or alternate is able to act at a meeting of 
stockholders, the person presiding at the meeting shall appoint one or more 
inspectors to act at the meeting.  

       (c)    INSPECTOR'S OATH.  Each inspector of election, before entering 
upon the discharge of his duties, shall take and sign an oath faithfully to 
execute the duties of inspector with strict impartiality and according to the 
best of such inspector's ability.  

       (d)    DUTIES OF INSPECTORS.  At a meeting of stockholders, the 
inspectors of election shall (i) ascertain the number of shares outstanding 
and the voting power of each share, (ii) determine the shares represented at 
a meeting and the validity of proxies and ballots, (iii) count all votes and 
ballots, (iv) determine and retain for a reasonable period of time a record 
of the disposition of any challenges made to any determination by the 
inspectors, and (v) certify their determination of the number of shares 
represented at the meeting, and their count of all votes and ballots.  The 
inspectors may appoint or retain other persons or entities to assist the 
inspectors in the performance of the duties of the inspectors.

                                      -4-


       (e)    OPENING AND CLOSING OF POLLS.  The date and time of the opening 
and the closing of the polls for each matter upon which the stockholders will 
vote at a meeting shall be announced by the chairperson of the meeting.  No 
ballot, proxies or votes, nor any revocations thereof or changes thereto, 
shall be accepted by the inspectors after the closing of the polls unless the 
Court of Chancery upon application by a stockholder shall determine otherwise.

       (f)    DETERMINATIONS.  In determining the validity and counting of 
proxies and ballots, the inspectors shall be limited to an examination of the 
proxies, any envelopes submitted with those proxies, any information provided 
in connection with proxies in accordance with Section 212(c)(2) of the 
Delaware General Corporation Law, ballots and the regular books and records 
of the Corporation, except that the inspectors may consider other reliable 
information for the limited purpose of reconciling proxies and ballots 
submitted by or on behalf of banks, brokers, their nominees or similar 
persons which represent more votes than the holder of a proxy is authorized 
by the record owner to cast or more votes than the stockholder holds of 
record.  If the inspectors consider other reliable information for the 
limited purpose permitted herein, the inspectors at the time they make their 
certification of their determinations pursuant to this Section 1.11 shall 
specify the precise information considered by them, including the person or 
persons from whom they obtained the information, when the information was 
obtained, the means by which the information was obtained and the basis for 
the inspectors' belief that such information is accurate and reliable.

       SECTION 1.12: NOTICE OF STOCKHOLDER BUSINESS; NOMINATIONS.

       (a)    ANNUAL MEETING OF STOCKHOLDERS.

              (i)    Nominations of persons for election to the Board of

principal executive offices of the Corporation not later than the close of 
business on the sixtieth (60th) day nor earlier than the close of business on 
the ninetieth (90th) day prior to the first anniversary of the preceding

which such notice shall be timely if delivered in the same time period as if 
such meeting were a special meeting governed by subparagraph (b) of this 
Section 1.12); PROVIDED, HOWEVER, that in the event that the date of the 
annual meeting is more than thirty (30) days before or more than sixty (60) 
days after such anniversary date, notice by the stockholder to be timely must 
be so delivered not earlier than the close of business on the ninetieth 
(90th) day prior to such annual meeting and not later than the 

                                      -5-

annual meeting or the close of business on the tenth (10th) day following the 
day on which public announcement of the date of such meeting is first made by 
the Corporation.  Such stockholder's notice shall set forth: (a) as to each 
person whom the stockholder proposes to nominate for election or reelection 
as a director all information relating to such person that is required to be 
disclosed in solicitations of proxies for election of directors, or is 
otherwise required, in each case pursuant to Regulation 14A under the 
Securities Exchange Act of 1934, as amended (the "EXCHANGE ACT"), including 
such person's written consent to being named in the proxy statement as a 
nominee and to serving as a director if elected; (b) as to any other business 
that the stockholder proposes to bring before the meeting, a brief 
description of the business desired to be brought before the meeting, the 
reasons for conducting such business at the meeting and any material interest 
in such business of such stockholder and the beneficial owner, if any, on 
whose behalf the proposal is made; and (c) as to the stockholder giving the 
notice and the beneficial owner, if any, on whose behalf the nomination or 
proposal is made (1) the name and address of such stockholder, as they appear 
on the Corporation's books, and of such beneficial owner, and (2) the class 
and number of shares of the Corporation that are owned beneficially and held 
of record by such stockholder and such beneficial owner.

              (iii)  Notwithstanding anything in the second sentence of 
subparagraph (a)(ii) of this Section 1.12 to the contrary, in the event that 
the number of directors to be elected to the Board of Directors of the 
Corporation is increased and there is no public announcement by the 
Corporation naming all of the nominees for director or specifying the size of 
the increased board of directors at least seventy (70) days prior to the 
first anniversary of the preceding year's annual meeting (or, if the annual 
meeting is held more than thirty (30) days before or sixty (60) days after 
such anniversary date, at least seventy (70) days prior to such annual 
meeting), a stockholder's notice required by this Section 1.12 shall also be 
considered timely, but only with respect to nominees for any new positions 
created by such increase, if it shall be delivered to the Secretary of the 
Corporation at the principal executive office of the Corporation not later 
than the close of business on the tenth (10th) day following the day on which 
such public announcement is first made by the Corporation.

       (b)    SPECIAL MEETINGS OF STOCKHOLDERS.  Only such business shall be 
conducted at a special meeting of stockholders as shall have been brought 
before the meeting pursuant to the Corporation's notice of such meeting.  
Nominations of persons for election to the Board of Directors may be made at 
a special meeting of stockholders at which directors are to be elected 
pursuant to the Corporation's notice of such meeting (i) by or at the 
direction of the Board of Directors or (ii) provided that the Board of 
Directors has determined that directors shall be elected at such meeting, by 
any stockholder of the Corporation who is a stockholder of record at the time 
of giving of notice of the special meeting, who shall be entitled to vote at 
the meeting and who complies with the notice procedures set forth in this 
Section 1.12.  In the event the Corporation calls a special meeting of 
stockholders for the purpose of electing one or more directors to the Board 
of Directors, any such stockholder may nominate a person or persons (as the 
case may be), for election to such position(s) as specified in the 
Corporation's notice of meeting, if the stockholder's notice required by 
subparagraph (a)(ii) of this Section 1.12 shall be delivered to the Secretary 
of the Corporation at the principal executive offices of the Corporation

                                      -6-

which public announcement is first made of the date of the special meeting 
and of the nominees proposed by the Board of Directors to be elected at such 
meeting.

       (c)    GENERAL.

              (i)    Only such persons who are nominated in accordance with 
the procedures set forth in this Section 1.12 shall be eligible to serve as 
directors and only such business shall be conducted at a meeting of 
stockholders as shall have been brought before the meeting in accordance with 
the procedures set forth in this Section 1.12.  Except as otherwise provided 
by law or these Bylaws, the chairperson of the meeting shall have the power 
and duty to determine whether a nomination or any business proposed to be 
brought before the meeting was made or proposed, as the case may be, in 
accordance with the procedures set forth in this Section 1.12 and, if any 
proposed nomination or business is not in compliance herewith, to declare 
that such defective proposal or nomination shall be disregarded.

              (ii)   For purposes of this Section 1.12, the term "PUBLIC 
ANNOUNCEMENT" shall mean disclosure in a press release reported by the Dow 
Jones News Service, Associated Press or comparable national news service or 
in a document publicly filed by the Corporation with the Securities and 
Exchange Commission pursuant to section 13, 14 or 15(d) of the Exchange Act.

              (iii)  Notwithstanding the foregoing provisions of this Section 
1.12, a stockholder shall also comply with all applicable requirements of the 
Exchange Act and the rules and regulations thereunder with respect to the 
matters set forth herein.  Nothing in this Section 1.12 shall be deemed to 
affect any rights of stockholders to request inclusion of proposals in the 
Corporation's proxy statement pursuant to Rule 14a-8 under the Exchange Act.

                               BOARD OF DIRECTORS

       SECTION 2.1:  NUMBER; QUALIFICATIONS.  The Board of Directors shall 
consist of one or more members.  The initial number of directors shall be 
seven (7), and thereafter shall be fixed from time to time by resolution of 
the Board of Directors.  No decrease in the authorized number of directors 
constituting the Board of Directors shall shorten the term of any incumbent 
director. Directors need not be stockholders of the Corporation.

       SECTION 2.2:  ELECTION; RESIGNATION; REMOVAL; VACANCIES.  Subject to 
the rights of the holders of any series of Preferred Stock to elect 
additional directors under specified circumstances, following the closing of 
the corporation's initial public offering pursuant to an effective 
registration statement under the Securities Act of 1933, as amended, covering 
the offer and sale of Common Stock to the public (the "INITIAL PUBLIC 
OFFERING"), the directors shall be divided, with respect to the time for 
which they severally hold office, into three classes designated as Class I, 
Class II and Class III, respectively.  Directors shall be assigned to each 

                                      -7-


class in accordance with a resolution or resolutions adopted by the Board of 
Directors, with the number of directors in each class to be divided as 
equally as possible.  The term of office of the Class I directors shall 
expire at the corporation's first annual meeting of stockholders following 
the closing of the Initial Public Offering, the term of office of the Class 
II directors shall expire at the corporation's second annual meeting of 
stockholders following the closing of the Initial Public Offering, and the 
term of office of the Class III directors shall expire at the corporation's 
third annual meeting of stockholders following the closing of the Initial 
Public Offering.  At each annual meeting of stockholders commencing with the 
first annual meeting of stockholders following the closing of the Initial 
Public Offering, directors elected to succeed those directors of the class 
whose terms then expire shall be elected for a term of office to expire at 
the third succeeding annual meeting of stockholders after their election.  
Prior to the closing of the Initial Public Offering, each director shall hold 
office until the next annual meeting of stockholders and until such 
director's successor is elected and qualified, or until such director's 
earlier death, resignation or removal.  Any director may resign at any time 
upon written notice to the Corporation.  Subject to the rights of the holders 
of any series of Preferred Stock, any vacancy occurring in the Board of 
Directors for any cause, and any newly created directorship resulting from 
any increase in the authorized number of directors, shall, unless (i) the 
Board of Directors determines by resolution that any such vacancies or newly 
created directorships shall be filled by the stockholders, or (ii) as 
otherwise provided by law, be filled only by the affirmative vote of a 
majority of the directors then in office, although less than a quorum, or by 
a sole remaining director, and not by the stockholders.  Any director elected 
in accordance with the preceding sentence shall hold office for the remainder 
of the full term of the director for which the vacancy was created or 
occurred.  Subject to the rights of any holders of Preferred Stock, any 
director or the entire Board of Directors may be removed, only with cause, by 
the holders of a majority of the shares then entitled to vote at an election 
of directors.

       SECTION 2.3:  REGULAR MEETINGS.  Regular meetings of the Board of 
Directors may be held at such places, within or without the State of

State of Delaware, as the person or persons calling the meeting shall fix.

in writing, by the person or persons calling the meeting to all directors at 
least four (4) days before the meeting if the notice is mailed, or at least 
twenty-four (24) hours before the meeting if such notice is given by 
telephone, hand delivery, telegram, telex, mailgram, facsimile or similar 
communication method.  Unless otherwise indicated in the notice, any and all 
business may be transacted at a special meeting.

       SECTION 2.5:  TELEPHONIC MEETINGS PERMITTED.  Members of the Board of 
Directors, or any committee of the Board, may participate in a meeting of the 
Board or such committee by means of conference telephone or similar 
communications equipment by means of which all 

                                      -8-


persons participating in the meeting can hear each other, and participation 
in a meeting pursuant to conference telephone or similar communications 
equipment shall constitute presence in person at such meeting.

       SECTION 2.6:  QUORUM; VOTE REQUIRED FOR ACTION.  At all meetings of 
the Board of Directors a majority of the total number of authorized directors 
shall constitute a quorum for the transaction of business.  Except as 
otherwise provided herein or in the Certificate of Incorporation, or required 
by law, the vote of a majority of the directors present at a meeting at which 
a quorum is present shall be the act of the Board of Directors.

       SECTION 2.7:  ORGANIZATION.  Meetings of the Board of Directors shall 
be presided over by the Chairperson of the Board of Directors, or in such 
person's absence by the President, or in such person's absence by a 
chairperson chosen at the meeting.  The Secretary shall act as secretary of 
the meeting, but in such person's absence the chairperson of the meeting may

       SECTION 2.8:  WRITTEN ACTION BY DIRECTORS.  Any action required or 
permitted to be taken at any meeting of the Board of Directors, or of any 
committee thereof, may be taken without a meeting if all members of the Board

writing or writings are filed with the minutes of proceedings of the Board or 
committee, respectively.

       SECTION 2.9:  POWERS.  The Board of Directors may, except as otherwise 
required by law or the Certificate of Incorporation, exercise all such powers 
and do all such acts and things as may be exercised or done by the

more committees, each committee to consist of one or more of the directors of 
the Corporation.  The Board of Directors may designate one or more directors

disqualified member at any meeting of the committee.  In the absence or 
disqualification of a member of the committee, the member or members thereof 
present at any meeting of such committee who are not disqualified from 
voting, whether or not such member or members constitute a quorum, may 
unanimously appoint another member of the Board of Directors to act at the 
meeting in place of any such absent or disqualified member.  Any such 
committee, to the extent provided in a resolution of the Board of Directors, 
shall have and may exercise all the powers and authority of the Board of 
Directors in the management of the business and affairs of the Corporation 
and may authorize the seal of the Corporation to be 

                                      -9-


affixed to all papers that may require it; but no such committee shall have 
the power or authority in reference to the following matters:  (i) approving 
or adopting, or recommending to the stockholders, any action or matter 
expressly required by the Delaware General Corporation Law to be submitted to 
stockholders for approval or (ii) adopting, amending or repealing any bylaw 
of the Corporation.

       SECTION 3.2:  COMMITTEE RULES.  Unless the Board of Directors

of such rules each committee shall conduct its business in the same manner as 
the Board of Directors conducts its business pursuant to Article II of these 
Bylaws.

the signatures on the certificate may be a facsimile.

       SECTION 5.2:  LOST, STOLEN OR DESTROYED STOCK CERTIFICATES; ISSUANCE

                                   ARTICLE VI
                                          
                                INDEMNIFICATION

       SECTION 6.1   INDEMNIFICATION OF OFFICERS AND DIRECTORS.  Each person 
who was or is made a party to, or is threatened to be made a party to, or is 
involved in any action, suit or proceeding, whether civil, criminal, 
administrative or investigative (a "PROCEEDING"), by reason of the fact that 
such person (or a person of whom such person is the legal representative), is 
or was a director or officer of the Corporation or a Reincorporated 
Predecessor (as defined below) or is or was serving at the request of the 
Corporation or a Reincorporated Predecessor (as defined below) as a director 
or officer of another corporation, or of a partnership, joint venture, trust 
or other enterprise, including service with respect to employee benefit 
plans, shall be indemnified and held harmless by the Corporation to the 
fullest extent permitted by the Delaware General Corporation Law, against all 
expenses, liability and loss (including attorneys' fees, judgments, fines, 
ERISA excise taxes and penalties and amounts paid or to be paid in 
settlement) reasonably incurred or suffered by such person in connection 
therewith, provided such person acted in good faith and in a manner which the 
person 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 the person's conduct was unlawful.  Such 
indemnification shall continue as to a person who has ceased to be a director 
or officer and shall inure to the benefit of such person's heirs, executors 
and administrators.  Notwithstanding the foregoing, the Corporation shall 
indemnify any such person seeking indemnity 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.  As 
used herein, the term "REINCORPORATED PREDECESSOR" means a corporation that 
is merged with and into the Corporation in a statutory merger where (a) the 
Corporation is the surviving corporation of such merger; (b) the primary 
purpose of such merger is to change the corporate domicile of the 
Reincorporated Predecessor to Delaware.

       SECTION 6.2:  ADVANCE OF EXPENSES.  The Corporation shall pay all 
expenses (including attorneys' fees) incurred by such a director or officer 
in defending any such Proceeding as they are incurred in advance of its final 
disposition; PROVIDED, HOWEVER, that if the Delaware General Corporation Law 
then so requires, the payment of such expenses incurred by such a director or 
officer in advance of the final disposition of such Proceeding shall be made 
only upon delivery to the Corporation of an undertaking, by or on behalf of 
such director or officer, to repay all amounts so advanced if it should be 
determined ultimately that such director or officer is not entitled to be 
indemnified under this Article VI or otherwise; and PROVIDED, FURTHER, that 
the Corporation shall not be required to advance any expenses to a person 
against whom the Corporation directly brings a claim, in a Proceeding, 
alleging that such person has breached such person's duty of loyalty to the 
Corporation, committed an act or omission not in good faith or that involves 
intentional misconduct or a knowing violation of law, or derived an improper 
personal benefit from a transaction.

       SECTION 6.3:  NON-EXCLUSIVITY OF RIGHTS.  The rights conferred on any 
person in this Article VI shall not be exclusive of any other right that such 
person may have or hereafter 

                                     -13-


acquire under any statute, provision of the Certificate of Incorporation, 
Bylaw, agreement, vote or consent of stockholders or disinterested directors, 
or otherwise.  Additionally, nothing in this Article VI shall limit the 
ability of the Corporation, in its discretion, to indemnify or advance 
expenses to persons whom the Corporation is not obligated to indemnify or 
advance expenses pursuant to this Article VI.

       SECTION 6.4:  INDEMNIFICATION CONTRACTS.  The Board of Directors is 
authorized to cause the Corporation to enter into indemnification contracts 
with any director, officer, employee or agent of the Corporation, or any 
person serving at the request of the Corporation as a director, officer, 
employee or agent of another corporation, partnership, joint venture, trust 
or other enterprise, including employee benefit plans, providing 
indemnification rights to such person.  Such rights may be greater than those 
provided in this Article VI.

       SECTION 6.5:  EFFECT OF AMENDMENT.  Any amendment, repeal or 
modification of any provision of this Article VI shall be prospective only, 
and shall not adversely affect any right or protection conferred on a person 
pursuant to this Article VI and existing at the time of such amendment, 
repeal or modification.
                                       
                                  ARTICLE VII
                                          
                                    NOTICES

       SECTION 7.1:  NOTICE.  Except as otherwise specifically provided 
herein or required by law, all notices required to be given pursuant to these 
Bylaws shall be in writing and may in every instance be effectively given by 
hand delivery (including use of a delivery service), by depositing such 
notice in the mail, postage prepaid, or by sending such notice by prepaid 
telegram, telex, overnight express courier, mailgram or facsimile.  Any such 
notice shall be addressed to the person to whom notice is to be given at such 
person's address as it appears on the records of the Corporation.  The notice 
shall be deemed given (i) in the case of hand delivery, when received by the 
person to whom notice is to be given or by any person accepting such notice 
on behalf of such person, (ii) in the case of delivery by mail, upon deposit 
in the mail, (iii) in the case of delivery by overnight express courier, when 
dispatched, and (iv) in the case of delivery via telegram, telex, mailgram or 
facsimile, when dispatched.

       SECTION 7.2:  WAIVER OF NOTICE.  Whenever notice is required to be 
given under any provision of these Bylaws, a written waiver of notice, signed 
by the person entitled to notice, whether before or after the time stated 
therein, shall be deemed equivalent to notice.  Attendance of a person at a 
meeting shall constitute a waiver of notice of such meeting, except when the 
person attends a meeting for the express purpose of objecting at the 
beginning of the meeting to the transaction of any business because the 
meeting is not lawfully called or convened.  Neither the business to be 
transacted at, nor the purpose of, any regular or special meeting of the 
stockholders, directors or members of a committee of directors need be 
specified in any written waiver of notice.

                                  ARTICLE VIII
                                          
                              INTERESTED DIRECTORS

       SECTION 8.1:  INTERESTED DIRECTORS; QUORUM.  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 this reason, or solely because the director or 
officer is present at or participates in the meeting of the Board of 
Directors or committee thereof that authorizes the contract or transaction, 
or solely because his, her or their votes are counted for such purpose, if: 
(i) the material facts as to his, her or their relationship or interest and 
as to the contract or transaction are disclosed or are known to the Board of 
Directors or the committee, and the Board of Directors or committee in good 
faith authorizes the contract or transaction by the affirmative votes of a 
majority of the disinterested directors, even though the disinterested 
directors be less than a quorum; (ii) the material facts as to his, her or 
their relationship or interest and as to the contract or transaction are 
disclosed or are known to the stockholders entitled to vote thereon, and the 
contract or transaction is specifically approved in good faith by vote of the 
stockholders; or (iii) 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, a committee thereof, or the stockholders.  Interested 
directors may be counted in determining the presence of a quorum at a meeting 
of the Board of Directors or of a committee which authorizes the contract or 
transaction.

                                   ARTICLE IX
                                          
                                 MISCELLANEOUS

be determined by resolution of the Board of Directors.

corporate seal, which shall have the name of the Corporation inscribed 
thereon and shall otherwise be in such form as may be approved from time to 
time by the Board of Directors.

       SECTION 9.3:  FORM OF RECORDS.  Any records maintained by the 
Corporation in the regular course of its business, including its stock 
ledger, books of account and minute books, may be kept on, or be in the form 
of, magnetic tape, diskettes, photographs, microphotographs or any other 
information storage device, provided that the records so kept can be 
converted into clearly legible form within a reasonable time.  The 
Corporation shall so convert any records so kept upon the request of any 
person entitled to inspect the same.

       SECTION 9.4:  RELIANCE UPON BOOKS AND RECORDS.  A member of the Board 
of Directors, or a member of any committee designated by the Board of 
Directors shall, in the performance of such person's duties, be fully 
protected in relying in good faith upon records of the Corporation and upon 
such information, opinions, reports or statements presented to the 
Corporation by any 

                                     -15-


of the Corporation's officers or employees, or committees of the Board of 
Directors, or by any other person as to matters the member reasonably 
believes are within such other person's professional or expert competence and 
who has been selected with reasonable care by or on behalf of the Corporation.

       SECTION 9.5:  CERTIFICATE OF INCORPORATION GOVERNS.  In the event of 
any conflict between the provisions of the Corporation's Certificate of 
Incorporation and Bylaws, the provisions of the Certificate of Incorporation 
shall govern.

       SECTION 9.6:  SEVERABILITY.  If any provision of these Bylaws shall be 
held to be invalid, illegal, unenforceable or in conflict with the provisions 
of the Corporation's Certificate of Incorporation, then such provision shall 
nonetheless be enforced to the maximum extent possible consistent with such 
holding and the remaining provisions of these Bylaws (including without 
limitation, all portions of any section of these Bylaws containing any such 
provision held to be invalid, illegal, unenforceable or in conflict with the 
Certificate of Incorporation, that are not themselves invalid, illegal, 
unenforceable or in conflict with the Certificate of Incorporation) shall 
remain in full force and effect.

                                   ARTICLE X
                                          
                                   AMENDMENT

       SECTION 10.1: AMENDMENTS.  Stockholders of the Corporation holding a 
majority of the Corporation's outstanding voting stock then entitled to vote 
at an election of directors shall have the power to adopt, amend or repeal 
Bylaws. To the extent provided in the Corporation's Certificate of 
Incorporation, the Board of Directors of the Corporation shall also have the 
power to adopt, amend or repeal Bylaws of the Corporation.
