                                   ARTICLE I

                                  STOCKHOLDERS

     1.1   PLACE OF MEETINGS. All meetings of stockholders shall be held at such
place as may be designated from time to time by the Board of Directors, the
Chairman of the Board or the President or, if not so designated, at the
principal office of the corporation.

     1.2   ANNUAL MEETING. Unless directors are elected by consent in lieu of an
annual meeting, the annual meeting of stockholders for the election of directors
and for the transaction of such other business as may properly be brought before
the meeting shall be held during the month of March on a date and at a time
designated by the Board of Directors, the Chairman of the Board or the President
(which date shall not be a legal holiday in the place where the meeting is to be
held). If no annual meeting is held in accordance with the foregoing provisions,
a special meeting may be held in lieu of the annual meeting, and any action
taken at that special meeting shall have the same effect as if it had been taken
at the annual meeting, and in such case all references in these By-laws to the
annual meeting of the stockholders shall be deemed to refer to such special
meeting.

     1.3   SPECIAL MEETINGS. Special meetings of stockholders for any purpose or
purposes may be called at any time by the Board of Directors, the Chairman of
the Board or the President, but such special meetings may not be called by any
other person or persons. Business transacted at any special meeting of
stockholders shall be limited to matters relating to the purpose or purposes
stated in the notice of meeting.

     1.4   NOTICE OF MEETINGS. Except as otherwise provided by law, written
notice of each meeting of stockholders, whether annual or special, shall be
given not less than 10 nor more than 60 days before the date of the meeting to
each stockholder entitled to vote at such meeting. The notices of all meetings
shall state the place, date and time of the meeting and the means of remote
communications, if any, by which stockholders and proxyholders may be deemed to
be present in person and vote at such meeting. The notice of a special meeting
shall state, in addition, the purpose or purposes for which the meeting is
called. If notice is given by mail, such notice shall be deemed given when
deposited in the United States mail, postage prepaid,

directed to the stockholder at such stockholder's address as it appears on the
records of the corporation.

     1.5   VOTING LIST. The Secretary shall prepare, at least 10 days before
every meeting of stockholders, a complete list of the stockholders entitled to
vote at the meeting, arranged in alphabetical order, and showing the address of
each stockholder and the number of shares registered in the name of each
stockholder. The list shall 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.

     1.6   QUORUM. Except as otherwise provided by law, the Certificate of
Incorporation or these By-laws, the holders of a majority of the shares of the
capital stock of the corporation issued and outstanding and entitled to vote at
the meeting, present in person or represented by proxy, shall constitute a
quorum for the transaction of business. A quorum, once established at a meeting,
shall not be broken by the withdrawal of enough votes to leave less than a
quorum.

     1.7   ADJOURNMENTS. Any meeting of stockholders may be adjourned from time
to time to any other time and to any other place at which a meeting of
stockholders may be held under these By-laws by the stockholders present or
represented at the meeting and entitled to vote, although less than a quorum,
or, if no stockholder is present, by any officer entitled to preside at or to
act as secretary of such meeting. At the adjourned meeting, the corporation may
transact any business which might have been transacted at the original meeting.

     1.8   VOTING AND PROXIES. Each stockholder shall have one vote for each
share of stock entitled to vote held of record by such stockholder, unless
otherwise provided by law or the Certificate of Incorporation. Each stockholder
of record entitled to vote at a meeting of stockholders, or to express consent
or dissent to corporate action without a meeting, may vote or express such
consent or dissent in person or may authorize another person or persons to vote
or act for such stockholder by a proxy executed and delivered to the Secretary
of the corporation. No such proxy shall be voted or acted upon after six months
from the date of its execution, unless the proxy expressly provides for a longer
period.

     1.9   ACTION AT MEETING. When a quorum is present at any meeting, any
matter other than the election of directors to be voted upon by the stockholders
at such meeting shall be decided by the vote of the holders of shares of stock
having a majority of the votes cast by the holders of all of the shares of stock
present or represented and voting on such matter (or if there are two or more
classes of stock entitled to vote as separate classes, then in the case of each
such class, the holders of a majority of the stock of that class present or
represented and voting on such matter), except when a different vote is required
by law, the Certificate of Incorporation or these By-Laws. When a quorum is
present at any meeting, any election by stockholders of directors shall be
determined by a plurality of the votes cast on the election.

     1.10  CONDUCT OF MEETINGS.

           (a)  CHAIRMAN OF MEETING. Meetings of stockholders shall be presided
over by the Chairman of the Board, if any, or in the Chairman's absence by the
Vice Chairman of the Board, if any, or in the Vice Chairman's absence by the
President, or in the President's absence by a Vice President, or in the absence
of all of the foregoing persons by a chairman designated by the Board of
Directors, or in the absence of such designation by a chairman chosen by vote of
the stockholders at the meeting. The Secretary shall act as secretary of the
meeting, but in the Secretary's absence the chairman of the meeting may appoint
any person to act as secretary of the meeting.

           (b)  RULES, REGULATIONS AND PROCEDURES. The Board of Directors of the
corporation may adopt by resolution such rules, regulations and procedures for
the conduct of any meeting of stockholders of the corporation as it shall deem
appropriate. Except to the extent inconsistent with such rules, regulations and
procedures as adopted by the Board of Directors, the chairman of any meeting of
stockholders shall have the right and authority to prescribe such rules,
regulations and procedures and to do 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 shall be determined; (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.

     1.11  ACTION WITHOUT MEETING.

           (a)  TAKING OF ACTION BY CONSENT. Any action required or permitted to
be taken at any annual or special meeting of stockholders of the corporation may
be taken without a meeting, without prior notice and without a vote, if a
consent in writing, setting forth the action so taken, is signed by the holders
of outstanding stock having not less than the minimum number of votes that would
be necessary to authorize or take such action at a meeting at which all shares
entitled to vote on such action were present and voted. Except as otherwise
provided by the Certificate of Incorporation, stockholders may act by written
consent to elect directors; provided, however, that, if such consent is less
than unanimous, such action by written consent may be in lieu of holding an
annual meeting only if all of the directorships to which directors could be

                                      - 3 -
<Page>

elected at an annual meeting held at the effective time of such action are
vacant and are filled by such action.

           (b)  NOTICE OF TAKING OF CORPORATE ACTION. Prompt notice of the
taking of corporate action without a meeting by less than unanimous written
consent shall be given to those stockholders who have not consented 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.

                                   ARTICLE II

                                    DIRECTORS

     2.1   GENERAL POWERS. The business and affairs of the corporation shall be
managed by or under the direction of a Board of Directors, who may exercise all
of the powers of the corporation except as otherwise provided by law, the
Certificate of Incorporation or these By-laws. In the event of a vacancy in the
Board of Directors, the remaining directors, except as otherwise provided by
law, may exercise the powers of the full Board until the vacancy is filled.

     2.2   NUMBER; ELECTION AND QUALIFICATION. The number of directors which
shall constitute the whole Board of Directors shall be determined from time to
time by resolution of the stockholders or the Board of Directors, but in no
event shall be less than one. The number of directors may be decreased at any
time and from time to time either by the stockholders or by a majority of the
directors then in office, but only to eliminate vacancies existing by reason of
the death, resignation, removal or expiration of the term of one or more
directors. The directors shall be elected at the annual meeting of stockholders
by such stockholders as have the right to vote on such election. Directors need
not be stockholders of the corporation.

     2.3   ENLARGEMENT OF THE BOARD. The number of directors may be increased at
any time and from time to time by the stockholders or by a majority of the
directors then in office.

     2.4   TENURE. Each director shall hold office until the next annual meeting
and until a successor is elected and qualified, or until such director's earlier
death, resignation or removal.

     2.5   VACANCIES. Unless and until filled by the stockholders, any vacancy
in the Board of Directors, however occurring, including a vacancy resulting from
an enlargement of the Board, may be filled by vote of a majority of the
directors then in office, although less than a quorum, or by a sole remaining
director. A director elected to fill a vacancy shall be elected for the
unexpired term of such director's predecessor in office, and a director chosen
to fill a position resulting from an increase in the number of directors shall
hold office until the next

                                      - 4 -
<Page>

annual meeting of stockholders and until a successor is elected and qualified,
or until such director's earlier death, resignation or removal.

     2.6   RESIGNATION. Any director may resign by delivering a resignation in
writing or by electronic transmission to the corporation at its principal office
or to the Chairman of the Board, the President or the Secretary. Such
resignation shall be effective upon receipt unless it is specified to be
effective at some later time or upon the happening of some later event.

     2.7   REGULAR MEETINGS. Regular meetings of the Board of Directors may be
held without notice at such time and place as shall be determined from time to
time by the Board of Directors; provided that any director who is absent when
such a determination is made shall be given notice of the determination. A
regular meeting of the Board of Directors may be held without notice immediately
after and at the same place as the annual meeting of stockholders.

     2.8   SPECIAL MEETINGS. Special meetings of the Board of Directors may be
held at any time and place designated in a call by the Chairman of the Board,
the President, two or more directors, or by one director in the event that there
is only a single director in office.

     2.9   NOTICE OF SPECIAL MEETINGS. Notice of any special meeting of
directors shall be given to each director by the Secretary or by the officer or
one of the directors calling the meeting. Notice shall be duly given to each
director (i) by giving notice to such director in person or by telephone at
least 24 hours in advance of the meeting, (ii) by sending a telegram or
delivering written notice by hand, to such director's last known business or
home address at least 48 hours in advance of the meeting, or (iii) by sending
written notice, via first-class mail or reputable overnight courier, to such
director's last known business or home address at least 72 hours in advance of
the meeting. A notice or waiver of notice of a meeting of the Board of Directors
need not specify the purposes of the meeting.

     2.10  MEETINGS BY CONFERENCE COMMUNICATIONS EQUIPMENT. Directors may
participate in meetings of the Board of Directors or any committee thereof by
means of conference telephone or other communications equipment by means of
which all persons participating in the meeting can hear each other, and
participation by such means shall constitute presence in person at such meeting.

     2.11  QUORUM. A majority of the total number of the whole Board of
Directors shall constitute a quorum at all meetings of the Board of Directors.
In the event one or more of the directors shall be disqualified to vote at any
meeting, then the required quorum shall be reduced by one for each such director
so disqualified; provided, however, that in no case shall less than one-third of
the number of directors fixed pursuant to Section 2.2 of these By-laws
constitute a quorum. In the absence of a quorum at any such meeting, a majority
of the directors present may adjourn the meeting from time to time without
further notice other than announcement at the meeting, until a quorum shall be
present.

                                      - 5 -
<Page>

     2.12  ACTION AT MEETING. At any meeting of the Board of Directors at which
a quorum is present, the vote of a majority of those present shall be sufficient
to take any action, unless a different vote is specified by law, the Certificate
of Incorporation or these By-laws.

     2.13  ACTION BY CONSENT. 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 or committee, as the case may be,
consent to the action in writing or by electronic transmission, and the written
consents and electronic transmissions are filed with the minutes of proceedings
of the Board or committee.

     2.14  REMOVAL. Any one or more or all of the directors may be removed, with
or without cause, by the holders of a majority of the shares then entitled to
vote at an election of directors, except that the directors elected by the
holders of a particular class or series of stock may be removed without cause
only by vote of the holders of a majority of the outstanding shares of such
class or series.

     2.15  COMMITTEES. The Board of Directors may designate 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. In the absence or disqualification of a member of a
committee, the member or members of the committee present at any meeting and 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 the place of any such absent or disqualified member. Any such
committee, to the extent provided in the resolution of the Board of Directors
and subject to the provisions of law, 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
affixed to all papers which may require it. Each such committee shall keep
minutes and make such reports as the Board of Directors may from time to time
request. Except as the Board of Directors may otherwise determine, any committee
may make rules for the conduct of its business, but unless otherwise provided by
the directors or in such rules, its business shall be conducted as nearly as
possible in the same manner as is provided in these By-laws for the Board of
Directors.

     2.16  COMPENSATION OF DIRECTORS. Directors may be paid such compensation
for their services and such reimbursement for expenses of attendance at meetings
as the Board of Directors may from time to time determine. No such payment shall
preclude any director from serving the corporation or any of its parent or
subsidiary corporations in any other capacity and receiving compensation for
such service.

     3.1   TITLES. The officers of the corporation shall consist of a President,
a Secretary, a Treasurer and such other officers with such other titles as the
Board of Directors may determine, including a Chairman of the Board, a Vice
Chairman of the Board, and one or more Vice Presidents, Assistant Treasurers,

offices may be held by the same person.

     3.4   TENURE. Except as otherwise provided by law, by the Certificate of
Incorporation or by these By-laws, each officer shall hold office until such
officer's successor is elected and qualified, unless a different term is
specified in the resolution electing or appointing such officer, or until such
officer's earlier death, resignation or removal.

     3.5   RESIGNATION AND REMOVAL. Any officer may resign by delivering a
written resignation to the corporation at its principal office or to the Chief
Executive Officer or the Secretary. Such resignation shall be effective upon
receipt unless it is specified to be effective at some later time or upon the
happening of some later event.

     Any officer may be removed at any time, with or without cause, by vote of a
majority of the entire number of directors then in office.

     Except as the Board of Directors may otherwise determine, no officer who
resigns or is removed shall have any right to any compensation as an officer for
any period following such officer's resignation or removal, or any right to
damages on account of such removal, whether such officer's compensation be by
the month or by the year or otherwise, unless such compensation is expressly
provided in a duly authorized written agreement with the corporation.

     3.6   VACANCIES. The Board of Directors may fill any vacancy occurring in
any office for any reason and may, in its discretion, leave unfilled for such
period as it may determine any offices other than those of President, Treasurer
and Secretary. Each such successor shall hold office for the unexpired term of
such officer's predecessor and until a successor is elected and qualified, or
until such officer's earlier death, resignation or removal.

of the Treasurer, the Assistant Treasurer, (or if there shall be more than one,
the Assistant Treasurers in the order determined by the Board of Directors)
shall perform the duties and exercise the powers of the Treasurer.

     3.12  SALARIES. Officers of the corporation shall be entitled to such
salaries, compensation or reimbursement as shall be fixed or allowed from time

                                   ARTICLE IV

                                  CAPITAL STOCK

     4.1   ISSUANCE OF STOCK. Unless otherwise voted by the stockholders and
subject to the provisions of the Certificate of Incorporation, the whole or any
part of any unissued balance of the authorized capital stock of the corporation
or the whole or any part of any shares of the authorized capital stock of the
corporation held in the corporation's treasury may be issued, sold, transferred
or otherwise disposed of by vote of the Board of Directors in such manner, for
such lawful consideration and on such terms as the Board of Directors may
determine.

     4.2   CERTIFICATES OF STOCK. Every holder of stock of the corporation shall
be entitled to have a certificate, in such form as may be prescribed by law and
by the Board of Directors, certifying the number and class of shares owned by
such holder in the corporation. Each such certificate shall be signed by, or in
the name of the corporation by, the Chairman or Vice-Chairman, if any, of the

corporation. Any or all of the signatures on the certificate may be a facsimile.

     Each certificate for shares of stock which are subject to any restriction
on transfer pursuant to the Certificate of Incorporation, these By-laws,
applicable securities laws or any agreement among any number of stockholders or
among such holders and the corporation shall have conspicuously noted on the
face or back of the certificate either the full text of the restriction or a
statement of the existence of such restriction.

     If the corporation shall be authorized to issue more than one class of
stock or more than one series of any class, the powers, designations,
preferences and relative, participating, optional or other special rights of
each class of stock or series thereof and the qualifications, limitations or
restrictions of such preferences and/or rights shall be set forth in full or
summarized on the face or back of each certificate representing shares of such
class or series of stock, provided that in lieu of the foregoing requirements
there may be set forth on the face or back of each certificate representing
shares of such class or series of stock a statement that the corporation will
furnish without charge to each stockholder who so requests a copy of the full
text of the powers, designations, preferences and relative, participating,
optional or other special rights of each class of stock or series thereof and
the qualifications, limitations or restrictions of such preferences and/or
rights.

     4.3   TRANSFERS. Except as otherwise established by rules and regulations
adopted by the Board of Directors, and subject to applicable law, shares of
stock may be transferred on the books of the corporation by the surrender to the
corporation or its transfer agent of the certificate representing such shares
properly endorsed or accompanied by a written assignment or power of attorney
properly executed, and with such proof of authority or the authenticity of
signature as the corporation or its transfer agent may reasonably require.
Except as may be otherwise required by law, by the Certificate of Incorporation
or by these By-laws, the corporation shall be entitled to treat the record
holder of stock as shown on its books as the owner of such stock for all
purposes, including the payment of dividends and the right to vote with respect
to such stock, regardless of any transfer, pledge or other disposition of such
stock until the shares have been transferred on the books of the corporation in
accordance with the requirements of these By-laws.

     4.4   LOST, STOLEN OR DESTROYED CERTIFICATES. The corporation may issue a
new certificate of stock in place of any previously issued certificate alleged
to have been lost, stolen, or destroyed, upon such terms and conditions as the
Board of Directors may prescribe, including the presentation of reasonable
evidence of such loss, theft or destruction and the giving of such indemnity as
the Board of Directors may require for the protection of the corporation or any
transfer agent or registrar.

     4.5   RECORD DATE. The Board of Directors may fix in advance a date as a
record date for the determination of the stockholders entitled to notice of or
to vote at any meeting of stockholders or to express consent (or dissent) to
corporate action without a meeting, or entitled to receive payment of any
dividend or other distribution or allotment of any rights in respect of

                                     - 10 -
<Page>

any change, conversion or exchange of stock, or for the purpose of any other
lawful action. Such record date shall not be more than 60 nor less than 10 days
before the date of such meeting, nor more than 10 days after the date of
adoption of a record date for a consent without a meeting, nor more than 60 days
prior to any other action to which such record date relates.

     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 before the day on which notice is given, or, if
notice is waived, at the close of business on the day before the day on which
the meeting is held. If no record date is fixed, the record date for determining
stockholders entitled to express consent to corporate action without a meeting,
when no prior action by the Board of Directors is necessary, shall be the day on
which the first consent is properly delivered to the corporation. If no record
date is fixed, the record date for determining stockholders for any other
purpose shall be at the close of business on the day on which the Board of
Directors adopts the resolution relating to such purpose.

     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.

the Certificate of Incorporation or by these By-laws, a written waiver, signed
by the person entitled to notice, or a waiver by electronic transmission by the
person entitled to notice, whether before, at or after the time stated in such
notice, 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.

     5.4   VOTING OF SECURITIES. Except as the Board of Directors may otherwise
designate, the President or the Treasurer may waive notice of, and act as, or
appoint any person or persons to act as, proxy or attorney-in-fact for this
corporation (with or without power of substitution) at,

                                     - 11 -

organization, the securities of which may be held by this corporation.

     5.5   EVIDENCE OF AUTHORITY. A certificate by the Secretary, or an
Assistant Secretary, or a temporary Secretary, as to any action taken by the
stockholders, directors, a committee or any officer or representative of the
corporation shall as to all persons who rely on the certificate in good faith be
conclusive evidence of such action.

     5.6   CERTIFICATE OF INCORPORATION. All references in these By-laws to the
Certificate of Incorporation shall be deemed to refer to the Certificate of
Incorporation of the corporation, as amended and in effect from time to time.

     5.7   TRANSACTIONS WITH INTERESTED PARTIES. No contract or transaction
between the corporation and one or more of the directors or officers, or between
the corporation and any other corporation, partnership, association, or other
organization in which one or more of the 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 a committee of the
Board of Directors at which the contract or transaction is authorized or solely
because any such director's or officer's votes are counted for such purpose, if:

           (a)  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 Board of Directors or the committee, and the Board 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;

           (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 stockholders entitled to vote thereon, and the contract or
transaction is specifically approved in good faith by vote of the stockholders;
or

           (c)  The contract or transaction is fair as to the corporation as of
the time it is authorized, approved or ratified, by the Board of Directors, a
committee of the Board of Directors, or the stockholders.

     Common or interested directors may be counted in determining the presence
of a quorum at a meeting of the Board of Directors or of a committee which
authorizes the contract or transaction.

     5.8   SEVERABILITY. Any determination that any provision of these By-laws
is for any reason inapplicable, illegal or ineffective shall not affect or
invalidate any other provision of these By-laws.

                                   AMENDMENTS

     6.1   BY THE BOARD OF DIRECTORS. These By-laws may be altered, amended or
repealed or new by-laws may be adopted by the affirmative vote of a majority of
the directors present at any regular or special meeting of the Board of
Directors at which a quorum is present.

     6.2   BY THE STOCKHOLDERS. These By-laws may be altered, amended or
repealed or new by-laws may be adopted by the affirmative vote of the holders of
a majority of the shares of the capital stock of the corporation issued and
outstanding and entitled to vote at any regular meeting of stockholders, or at
any special meeting of stockholders, provided notice of such alteration,
amendment, repeal or adoption of new by-laws shall have been stated in the
notice of such special meeting.
