                          AS ADOPTED ON JULY 31, 2001

                                  ARTICLE I:
                                  STOCKHOLDERS

         SECTION 1.01      ANNUAL MEETINGS; TIME AND PLACE OF MEETINGS.

                  If an annual meeting is required by applicable law, the
annual meeting of the stockholders of the Corporation shall be held for the
election of Directors and for the transaction of such other business as
properly may come before such meeting.

                  All meetings of stockholders shall be held at such place,
either within or without the State of Delaware, and on such date and at such
time, as may be fixed from time to time by the Board of Directors (or the
Chairman in the absence of a designation by the Board of Directors) and set
forth in the notice or waiver of notice of the meeting.

         SECTION 1.02      SPECIAL MEETINGS.

                  Special meetings of the stockholders may be called at any
time by the Chairman of the Board or the Chief Executive Officer or, in the
event of the Chief Executive Officer's absence or disability, by the President
or any Director who is also an officer (hereafter, an "Officer Director"). In
addition, a special meeting shall be called by the Chief Executive Officer (or,
in the event of his or her absence or disability, by the President or any
Officer Director), or by the Secretary (i) pursuant to a resolution approved by
a majority of the entire Board of Directors, or (ii) subject to the procedures
set forth in the second paragraph of this Section 1.02, upon receipt of a
written request therefor by stockholders holding in the aggregate not less than
fifteen percent (15%) of the outstanding shares of the Corporation at the time
entitled to vote at any meeting of the stockholders. If such officers shall
fail to call such meeting within one hundred (100) days after receipt of such
stockholder request, the stockholder executing such request may call such
meeting.

                  Upon request in writing sent by registered mail to the Chief
Executive Officer or the Secretary by any stockholder or stockholders entitled
to call a special meeting of stockholders pursuant to this Section 1.02, the
Board of Directors (or the Chairman in the absence of a designation by the
Board of Directors) shall determine a place and time for such meeting, which
time shall be not less than ninety (90) nor more than one hundred (100) days
after the receipt and determination of the validity of such request, and a
record date for the determination of stockholders entitled to vote at such
meeting in the manner set forth in Section 5.05 hereof. Following such receipt
and determination, it shall be the duty of the Secretary or any Assistant
Secretary to cause notice to be given to the stockholders entitled to vote at
such meeting, in the manner set forth in Section 1.03 hereof, that a meeting
will be held at the time and place so determined.

         SECTION 1.03      NOTICE OF MEETINGS; WAIVER.

                  The Secretary or any Assistant Secretary shall cause written
notice of the place, date and hour of each meeting of the stockholders, and, in
the case of a special meeting, the purpose or purposes for which such meeting
is called, to be given personally or by mail, not less than ten (10) nor more
than sixty (60) days prior to the meeting, to each stockholder of record
entitled to vote at such meeting, unless otherwise provided by Delaware Law. If
such notice is mailed, it shall be deemed to have been given to a stockholder
when deposited in the United States mail, postage prepaid, directed to the
stockholder at his or her address as it appears on the record of stockholders
of the Corporation, or, if he or she shall have filed with the Secretary of the
Corporation a written request that notices to him or her be mailed to some
other address, then directed to him or her at such other address. Such further
notice shall be given as may be required by law.

                  A written waiver of any notice of any annual or special
meeting signed by the person entitled thereto shall be deemed equivalent to
notice. Neither the business to be transacted at, nor the purpose of, any
regular or special meeting of the stockholders need be specified in a written
waiver of notice. Attendance of a stockholder at a meeting of stockholders
shall constitute a waiver of notice of such meeting, except when the
stockholder attends a meeting for the express purpose of objecting, at the
beginning of the meeting, to the transaction of any business on the ground that
the meeting is not lawfully called or convened.

         SECTION 1.04      QUORUM.

                  Except as otherwise required by law or by the Certificate of
Incorporation, the presence in person or by proxy of the holders of record of a
majority of the shares entitled to vote at a meeting of stockholders shall
constitute a quorum for the transaction of business at such meeting.

         SECTION 1.05      VOTING.

                  At all meetings of stockholders for the election of directors
a plurality of the votes cast shall be sufficient to elect directors. Except as
otherwise required by the Certificate of Incorporation, these Bylaws, Delaware
Law, the rules or regulations of any stock exchange applicable to the
Corporation, or applicable law or pursuant to any regulation applicable to the
Corporation or its securities, the vote of a majority of the shares represented
in person or by proxy at any meeting at which a quorum is present shall be
sufficient for the transaction of any business at such meeting.

         SECTION 1.06      VOTING BY BALLOT.

                  No vote of the stockholders need be taken by written ballot
unless otherwise required by law. Any vote not required to be taken by ballot
may be conducted in any manner approved at the meeting at which such vote is
taken. Unless otherwise provided in the Certificate of Incorporation and
subject to Delaware Law, each stockholder shall be entitled to one vote for
each outstanding share of capital stock of the Corporation held by such
stockholder.

         SECTION 1.07      ADJOURNMENT.

                  If a quorum is not present at any meeting of the
stockholders, the stockholders present in person or by proxy shall have the
power to adjourn any such meeting from time to time until a quorum is present.
Notice of any adjourned meeting of the stockholders of the

                                      -2-
<PAGE>   6

Corporation need not be given if the place, date and hour thereof are announced
at the meeting at which the adjournment is taken, provided, however, that if
the adjournment is for more than thirty days, or if after the adjournment a new
record date for the adjourned meeting is fixed pursuant to Section 5.05 of
these Bylaws, a notice of the adjourned meeting, conforming to the requirements
of Section 1.03 hereof, shall be given to each stockholder of record entitled
to vote at such meeting. At any adjourned meeting at which a quorum is present,
any business may be transacted that might have been transacted at the original
meeting.

         SECTION 1.08      PROXIES.

                  Any stockholder entitled to vote at any meeting of the
stockholders may authorize another person or persons to vote at any such
meeting for him or her by proxy. A stockholder may authorize a valid proxy by
executing a written instrument or by causing his or her signature to be affixed
to such writing by any reasonable means including, but not limited to, by
facsimile signature, or by transmitting or authorizing the transmission of a
telegram, cablegram, electronic mail or other means of electronic transmission
to the person designated as the holder of the proxy, a proxy solicitation firm
or a like authorized agent. No such proxy shall be voted or acted upon after
the expiration of three (3) years from the date of such proxy, unless such
proxy provides for a longer period. Every proxy shall be revocable at the
pleasure of the stockholder executing it, except in those cases where
applicable law provides that a proxy shall be irrevocable. A stockholder may
revoke any proxy which is not irrevocable by attending the meeting and voting
in person or by filing an instrument in writing revoking the proxy or by
submitting another proxy bearing a later date to the Secretary. Proxies by
telegram, cablegram, electronic mail or other electronic transmission must
either set forth or be submitted with information from which it can be
determined that such telegram, cablegram, electronic mail or other electronic
transmission was authorized by the stockholder. Any copy, facsimile
telecommunication or other reliable reproduction of a writing or transmission
created pursuant to this section may be substituted or used in lieu of the
original writing or transmission for any and all purposes for which the
original writing or transmission could be used, provided that such copy,
facsimile telecommunication or other reproduction shall be a complete
reproduction of the entire original writing or transmission.

         SECTION 1.09      ORGANIZATION; PROCEDURE.

                  (a)      Duties of Officers. At every meeting of stockholders
the presiding officer shall be the Chairman or, in the event of his or her
absence or disability, the Chief Executive Officer or, in the event of their
absences or disabilities, the President or any Executive Vice President chosen
by resolution of the Board of Directors. The Secretary, or in the event of his
or her absence or disability, any Assistant Secretary designated by the
presiding officer, if any, or if there be no Assistant Secretary, in the
absence of the Secretary, an appointee of the presiding officer, shall act as
Secretary of the meeting and keep the minutes thereof.

                  (b)      Conduct of Meetings. 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 at the meeting by the
person presiding over the meeting. The Board of Directors may adopt by
resolution such rules and regulations for the conduct of the meeting of
stockholders as it shall deem appropriate. Except to the extent inconsistent
with such rules and regulations as adopted by the Board of Directors, the
chairman of any meeting of stockholders shall have the right and authority to
convene and to adjourn the meeting, to prescribe such rules, regulations and

                                      -3-
<PAGE>   7

procedures and to all such acts as, in the judgment of such chairman, are
appropriate for the proper conduct of the meeting. Such rules, regulations or
procedures, whether adopted by the Board of Directors or prescribed by the
chairman of the meeting, may include, without limitation, the following: (i)
the establishment of an agenda or order of business for the meeting; (ii) rules
and procedures for maintaining order at the meeting and the safety of those
present; (iii) limitations on attendance at or participation in the meeting to
stockholders of record of the Corporation, their duly authorized and
constituted proxies or such other persons as the chairman of the meeting shall
determine; (iv) restrictions on entry to the meeting after the time fixed for
the commencement thereof; and (v) limitations on the time allotted to questions
or comments by participants. Unless and to the extent determined by the Board
of Directors or the chairman of the meeting, meetings of stockholders shall not
be required to be held in accordance with the rules of parliamentary procedure.

         SECTION 1.10      NOTICE OF NOMINATIONS AND STOCKHOLDER BUSINESS.

                  (a)      Annual Meetings of Stockholders.

                           (i)      Nominations of persons for election to the
         Board of Directors of the Corporation and the proposal of business to
         be considered by the stockholders may be made at an annual meeting of
         stockholders (A) by or at the direction of the Board of Directors or
         the Chairman, or (B) by any stockholder of the Corporation who is
         entitled to vote at the meeting, who complies with the notice
         procedures set forth in clauses (ii) and (iii) of this paragraph and
         who was a stockholder of record at the time such notice is delivered
         to the Secretary of the Corporation.

                           (ii)     For nominations or other business to be
         properly brought before an annual meeting by a stockholder pursuant to
         clause (B) of paragraph (a)(i) of this Section 1.10, the stockholder
         must have given timely notice thereof in writing to the Secretary of
         the Corporation and any such other business must otherwise be a proper
         matter for stockholder action. To be timely, a stockholder's notice
         shall be delivered to the Secretary at the principal executive offices
         of the Corporation not later than the close of business on the
         ninetieth (90th) day nor earlier than the close of business on the one
         hundred twentieth (120th) day prior to the first anniversary of the
         preceding year's annual meeting (provided, however, that in the event
         that the date of the annual meeting is more than thirty (30) days
         before or more than seventy (70) days after such anniversary date,
         notice by the stockholder must be so delivered not earlier than the
         close of business on the one hundred twentieth (120th) day prior to
         such annual meeting and not later than the close of business on the
         later of the ninetieth (90th) day prior to such annual meeting or the
         tenth (10th) day following the day on which public announcement of the
         date of such meeting is first made by the Corporation). In no event
         shall an adjournment or postponement of an annual meeting (or the
         public announcement thereof) commence a new time period (or extend any
         time period) for the giving of a stockholder's notice as described
         above.

                           Such stockholder's notice shall set forth in writing
         (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

                                      -4-
<PAGE>   8

         Act"), and Rule 14A-11 thereunder, 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 text of the proposal or business (including the text of any
         resolutions proposed for consideration and in the event that such
         business includes a proposal to amend the Bylaws of the Corporation,
         the language of the proposed amendment), the reasons for conducting
         such business at the meeting and any material interest in such
         business of such stockholder and of any beneficial owner on whose
         behalf the proposal is made; and (C) as to the stockholder giving the
         notice and any beneficial owner on whose behalf the nomination or
         proposal is made, (1) the name and address of such stockholder, as it
         appears on the Corporation's books, and of such beneficial owner, (2)
         the class and number of shares of the Corporation which are owned
         beneficially and of record by such stockholder and such beneficial
         owner, (3) a representation that the stockholder is a holder of record
         of stock of the Corporation entitled to vote at such a meeting and
         intends to appear in person or by proxy at the meeting to propose such
         business or nomination, and (4) a representation whether the
         stockholder or the beneficial owner, if any, intends or is part of a
         group which intends to (a) deliver a proxy statement and/or form of
         proxy to holders of at least the percent of the Corporation's
         outstanding capital stock required to approve or adopt the proposal or
         elect the nominee and/or (b) otherwise solicit proxies from
         stockholders in support of such proposal or nomination. The
         Corporation may require any proposed nominee to furnish such other
         information as it may reasonably require to determine the eligibility
         of such proposed nominee to serve as a director of the Corporation.

                           (iii)    Notwithstanding anything in the second
         sentence of paragraph (a)(ii) of this Section 1.10 to the contrary, in
         the event that the number of Directors to be elected to the Board of
         Directors of the Corporation at an annual meeting is increased and
         there is no public announcement naming all of the nominees for
         Director or specifying the size of the increased Board of Directors
         made by the Corporation at least one hundred (100) days prior to the
         first anniversary of the preceding year's annual meeting, a
         stockholder's notice under this paragraph 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 at
         the principal executive offices 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.

inspector, shall take and sign an oath faithfully to execute the duties of
inspector with strict impartiality and according to the best of his or her
ability. The inspector shall:

<PAGE>   10

                           (iii)    count all votes and ballots;

                           (iv)     determine and retain for a reasonable
         period a record of the disposition of any challenges made to any
         determination by the inspectors; and

                           (v)      certify his or her determination of the
         number of shares represented at the meeting, and his or her count of
         all votes and ballots.

                  (b)      The inspector may appoint or retain other persons or
entities to assist in the performance of the duties of inspector.

                  (c)      When determining the shares represented and the
validity of proxies and ballots, the inspector shall be limited to an
examination of the proxies, any envelopes submitted with those proxies, any
proxies or other information provided in accordance with Section 1.08 of these
Bylaws, ballots and the regular books and records of the Corporation. The
inspector may consider other reliable information for the limited purpose of
reconciling proxies and ballots submitted by or on behalf of banks, brokers or
their nominees or a similar person 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 inspector considers other reliable
information as outlined in this section, the inspector, at the time of his or
her certification pursuant to (a)(v) of this Section 1.11, shall specify the
precise information considered, the person or persons from whom the information
was obtained, when this information was obtained, the means by which the
information was obtained, and the basis for the inspector's belief that such
information is accurate and reliable.

         SECTION 1.12      OPENING AND CLOSING OF POLLS.

                  The date and time for the opening and the closing of the
polls for each matter to be voted upon at a stockholder meeting shall be

from accepting any ballots, proxies or votes or any revocations thereof or
changes thereto after the closing of the polls, unless the Delaware Court of
Chancery upon application by a stockholder shall determine otherwise.

Incorporation or these Bylaws, any action required or permitted to be taken at

cause, only by the affirmative vote of the holders of at least 66 2/3% of the
voting power of all outstanding shares of stock of the Corporation entitled to
vote generally in the election of Directors, voting together as a single class.
Any vacancy in the Board of Directors caused by any such removal may be filled
at such meeting by the stockholders entitled to vote for the election of the
Director so removed. A Director filling any such vacancy shall hold office

of preferred stock, if any, to elect additional Directors under specified
circumstances, and except as provided in Section 2.12, if any vacancies shall
occur in the Board of Directors, by reason of death, resignation, removal or
otherwise, or if the authorized number of Directors shall be increased, the
Directors then in office shall continue to act, and such vacancies and newly
created directorships may be filled by a majority of the Directors then in
office, although less than a quorum. Whenever the holders of any class or
classes of stock or series thereof are entitled to elect one or more Directors
by the Certificate of Incorporation, vacancies and newly created directorships
of such class or classes or series may be filled by a majority of Directors
elected by such class or classes or series thereof then in office, or by a sole
remaining Director so elected. A Director elected to fill a vacancy or a newly
created directorship shall hold office for a term that shall coincide with the
term of the Class to which such director shall have been elected until his or
her successor has been elected and qualified or until his or her earlier death,
resignation or removal. If there are no Directors in office, then an election
of Directors may be held in accordance with Delaware Law. Unless otherwise
provided in the Certificate of Incorporation, when one or more directors shall
resign from the Board, effective at a future date, a majority of the Directors
then in office, including those who have so resigned, shall have the power to
fill such vacancy or vacancies, the vote thereon to take effect when such
resignation or resignations shall become effective, and each Director so chosen
shall hold office as provided in the filing of other vacancies.

         SECTION 2.14      COMPENSATION.

resolution of the Board of Directors.

         SECTION 2.15      RELIANCE ON ACCOUNTS AND REPORTS, ETC.

                  A Director, and any member of any committee designated by the
Board of Directors shall, in the performance of such Director's duties, be
fully protected in relying in good faith upon the records of the Corporation
and upon information, opinions, reports or statements presented to the
Corporation by any of the Corporation's officers or employees, or Committees
designated by the Board of Directors, or by any other person as to the matters

as from time to time may be fixed by the Board of Directors. The Board of
Directors may designate one or more Directors as alternate members of any such
committee, who may replace any absent or disqualified member or members at any
meeting of such committee. Thereafter, members (and alternate members, if any)
of each such committee may be designated at the annual meeting of the Board of
Directors. Any such committee may be abolished or re-designated from time to
time by the Board of Directors. Each member (and each alternate member) of any

Director, or until his or her earlier death, resignation or removal.

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 affixed to all papers which may
require it; but no such committee shall have the power or authority in

be submitted to the stockholders for approval or (ii) adopting, amending or
repealing any bylaw of the Corporation.

         SECTION 3.03      PROCEEDINGS.

                  Each committee may fix its own rules of procedure and may
meet at such place (within or without the State of Delaware), at such time and
upon such notice, if any, as it shall determine from time to time. Each
committee shall keep minutes of its proceedings and shall report such
proceedings to the Board of Directors at the meeting of the Board of Directors
next following any such proceedings.

         SECTION 3.04      QUORUM AND MANNER OF ACTING.

                  Except as may be otherwise provided in the resolution
creating such committee, at all meetings of any committee the presence of
members (or alternate members) constituting a majority of the total authorized
membership of such committee shall constitute a quorum for the transaction of
business. The act of the majority of the members present at any meeting at
which a quorum is present shall be the act of such committee. Any action
required or permitted to be taken at any meeting of any such committee may be
taken without a meeting, if all members of such committee shall consent to such
action in writing and such writing or writings are filed with the minutes of
the proceedings of the committee. The members of any such committee shall act
only as a committee, and the individual members of such committee shall have no
power as such.

Board of Directors. The Board of Directors from time to time may delegate to
any officer or agent the power to appoint subordinate officers or agents and to

         SECTION 5.01      CERTIFICATES OF STOCK, UNCERTIFICATED SHARES.

                  The shares of the Corporation shall be represented by
certificates, provided that the Board of Directors may provide by resolution or
resolutions that some or all of any or all classes or series of the stock of
the Corporation shall be uncertificated shares. Any such resolution shall not
apply to shares represented by a certificate until each certificate is
surrendered to the Corporation. Notwithstanding the adoption of such a
resolution by the Board of Directors, every holder of stock in the Corporation
represented by certificates, and upon request every holder of uncertificated
shares shall be entitled to have a certificate signed by, or in the name of,
the Corporation, by the Chief Executive Officer, the President or an Executive
Vice President, and by the Treasurer or an Assistant Treasurer, or the
Secretary or an Assistant Secretary, representing the number of shares
registered in certificate form. Such certificate shall be in such form as the
Board of Directors may determine, to the extent consistent with applicable law,
the Certificate of Incorporation and these Bylaws.

         SECTION 5.02      SIGNATURES; FACSIMILE.

                  All of such signatures on the certificate referred to in
Section 5.01 of these Bylaws may be a facsimile, engraved or printed, to the
extent permitted by law. In case any officer, transfer agent or registrar who
has signed, or whose facsimile signature has been placed upon a certificate
representing shares of the Corporation shall have ceased to be such officer,
transfer agent or registrar before such certificate is issued, it may be issued
by the Corporation with the same effect as if he or she were such officer,
transfer agent or registrar at the date of issue.

         SECTION 5.03      LOST, STOLEN OR DESTROYED CERTIFICATES.

                  The Board of Directors may direct that a new certificate be
issued in place of any certificate theretofore issued by the Corporation
alleged to have been lost, stolen or destroyed, upon delivery to the Board of
Directors of an affidavit of the owner or owners of such certificate, setting
forth such allegation. The Board of Directors may require the owner of such
lost, stolen or destroyed certificate, or his or her legal representative, to
give the Corporation a bond sufficient to indemnify it against any claim that
may be made against it on account of the alleged loss, theft or destruction of
any such certificate or the issuance of any such new certificate.

         SECTION 5.04      TRANSFER OF STOCK.

                  Upon surrender to the Corporation or the transfer agent of
the Corporation of a certificate for shares, duly endorsed or accompanied by
appropriate evidence of succession, assignment or authority to transfer, the
Corporation shall issue a new certificate to the person entitled thereto,
cancel the old certificate and record the transaction upon its books. Within a

                                     -15-
<PAGE>   19

reasonable time after the transfer of uncertificated stock, the Corporation
shall send to the registered owner thereof a written notice containing the
information required to be set forth or stated on certificates pursuant to
Sections 151, 156, 202(a) or 218(a) of Delaware Law. Subject to the provisions
of the Certificate of Incorporation and these Bylaws, the Board of Directors
may prescribe such additional rules and regulations as it may deem appropriate
relating to the issue, transfer and registration of shares of the Corporation.

         SECTION 5.05      RECORD DATE.

                  In order to determine the stockholders entitled to notice of
or to vote at any meeting of stockholders or any adjournment thereof, the Board
of Directors may fix, in advance, a record date, which record date shall not
precede the date on 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. If no record date is fixed
the record date for determining stockholders entitled to notice of or to vote
at a meeting of stockholders shall be at 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 next preceding the day on which the meeting is
held. 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.

                  In order that the Corporation may determine the stockholders
entitled to receive payment of any dividend or other distribution or allotment
of any rights of the stockholders 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 a record date, which record date
shall not precede the date upon which the resolution fixing the record date is
adopted, and which record date shall be not more than sixty (60) days prior to
such action. If no record date is fixed, the record date for determining
stockholders for any such purpose shall be at the close of business on the day
on which the Board of Directors adopts the resolution relating thereto.

         SECTION 5.06      REGISTERED STOCKHOLDERS.

                  Prior to due surrender of a certificate for registration of
transfer, the Corporation may treat the registered owner as the person
exclusively entitled to receive dividends and other distributions, to vote, to
receive notice and otherwise to exercise all the rights and powers of the owner
of the shares represented by such certificate, and the Corporation shall not be
bound to recognize any equitable or legal claim to or interest in such shares
on the part of any other person, whether or not the Corporation shall have
notice of such claim or interests, except as otherwise required by applicable
law. Whenever any transfer of shares shall be made for collateral security, and
not absolutely, it shall be so expressed in the entry of the transfer if, when
the certificates are presented to the Corporation for transfer or
uncertificated shares are requested to be transferred, both the transferor and
transferee request the Corporation to do so.

         SECTION 5.07      TRANSFER AGENT AND REGISTRAR.

                  The Board of Directors may appoint one or more transfer
agents and one or more registrars, and may require all certificates
representing shares to bear the signature of any such transfer agents or
registrars.

time, in its absolute discretion, thinks proper as a reserve or reserves to
