appears on the records of the Corporation. An affidavit of the Secretary, an
Assistant Secretary, or the transfer agent of the Corporation that the notice
has been given shall, in the absence of fraud, be prima facie evidence of the
facts stated therein.

     Section 5.    QUORUM OF STOCKHOLDERS.

          (a)  Unless otherwise provided by law, at any meeting of stockholders,
     a majority of the shares of stock entitled to vote at such meeting, present
     in person or represented by proxy, shall constitute a quorum.

          (b)  At any meeting of stockholders at which a quorum is present, a
     majority of the shares of stock present in person or represented by proxy
     and entitled to vote may adjourn the meeting from time to time without
     notice other than announcement at the meeting. In the absence of a quorum,
     the officer presiding at the meeting shall have power to adjourn the
     meeting from time to time until a quorum is present. Notice need not be
     given of an adjourned meeting if the time and place thereof are announced
     at the meeting at which the adjournment is taken, except as provided in
     paragraph (d) below or as otherwise provided by law.

          (c)  At any adjourned meeting at which a quorum is present, any
     business may be transacted that might have been transacted at the original
     meeting, but only those stockholders entitled to vote at the original
     meeting shall be entitled to vote at any adjournment or adjournments
     thereof, unless a new record date is fixed by the Board of Directors.

          (d)  If an adjournment is for more than thirty days, or if after an
     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 adjourned meeting.

the Board, or, in his absence, the President, or, in his absence, a Vice
President, shall preside at meetings of stockholders. The Secretary, or, in his

     Section 8.    PROXIES. Any stockholder entitled to vote at a meeting of
stockholders may authorize another person or persons to act for him by proxy,
but no such proxy shall be voted or acted upon after three years from its date,
unless the proxy provides for a longer period. A duly executed proxy shall be
irrevocable if it states that it is irrevocable and if, and only as long as, it
is coupled with an interest sufficient in law to support an irrevocable power. A
stockholder may revoke any proxy that is not irrevocable by attending the
meeting and voting in person or by filing an instrument in writing revoking the
proxy or another duly executed proxy bearing a later date with the Secretary.

     Section 9.    LIST OF STOCKHOLDERS.

     of stock registered in the name of each stockholder.

          (b)  During ordinary business hours, for a period of at least ten days
     prior to the meeting, such list shall be open to the examination of any
     stockholder, for any purpose germane 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 meeting during the whole time thereof and may be inspected by any
     stockholder who is present.

     stockholders entitled to examine the stock ledger, the list required by
     this section, or the books of the Corporation, or to vote in person or by
     proxy at any meeting of stockholders.

supplement thereto) given by or at the direction of the Board of Directors, (b)
otherwise properly brought before the meeting by or at the direction of the
Board of Directors, or (c) otherwise properly brought before the meeting by a
stockholder. In addition to any other applicable requirements for business to be
properly brought before a meeting by a stockholder, the stockholder must have
given timely notice thereof in writing to the Secretary of the Corporation. To
be timely, a stockholder's notice must be delivered to or mailed and received at
the principal executive offices of the Corporation, not less than 90 days prior
to the meeting. A stockholder's notice to the Secretary shall set forth as to
each matter the stockholder proposes to bring before the meeting (i) a brief
description of the business desired to be brought before the meeting and the
reasons for conducting such business at the meeting, (ii) the name and record
address of the stockholder proposing such business, (iii) the class and number
of shares of the Corporation that are beneficially owned by the stockholder, and
(iv) any material interest of the stockholder in such business. In addition, any
such stockholder shall be required to provide such further information as may be
requested by the Corporation in advance to comply with federal securities laws,
rules and regulations. The Corporation may require evidence by any person giving
notice under this Section 10 that such person is a bona fide beneficial owner of
the Corporation's stock.

     Notwithstanding anything in these By-Laws to the contrary, no business
shall be conducted at the meeting except in accordance with the procedures set
forth in this Section 10; provided, however, that nothing in this Section 10
shall be deemed to preclude discussion by any stockholder of any business
properly brought before the meeting in accordance with said procedure.

     The chairman of a meeting shall, if the facts warrant, determine and
declare to the meeting that business was not properly brought before the meeting
in accordance with the provisions of this Section 10, and if he should so
determine, he shall so declare to the meeting and any such business not properly
brought before the meeting shall not be transacted.

     Section 11.   PROCEDURE FOR NOMINATION OF DIRECTORS. Only persons nominated
in accordance with the following procedures

                                        4

shall be eligible for election as Directors, except as may otherwise be provided
by the terms of the Corporation's Certificate of Incorporation with respect to
the rights of holders of any class or series of preferred stock to elect
Directors. Nominations of persons for election to the Board of Directors of the
Corporation may be made at a meeting of stockholders by or at the direction of
the Board of Directors, by any nominating Committee or person appointed by the
Board of Directors, or by any stockholder of the Corporation entitled to vote

set forth in this Section 11. Nominations other than those made by or at the
direction of the Board of Directors or any nominating committee or person
appointed by the Board of Directors shall be made pursuant to timely notice in
proper written form to the Secretary of the Corporation. To be timely, a
stockholder's request to nominate a person for Director, together with the
written consent of such person to serve as Director, must be received by the
Secretary of the Corporation (x) not less than 90 days nor more than 150 days
prior to the date fixed for the meeting or (y) with respect to an election of
Directors, before the close of business on the eighth day following the day on
which notice of such meeting is given to stockholders. To be in proper written
form, such stockholder's notice shall set forth in writing (a) as to each person
whom the stockholder proposes to nominate for election or re-election as a
Director (i) the name, age, business address and residence address for such
person, (ii) the principal occupation or employment of such person, (iii) the
class and number of shares of stock of the Corporation that are beneficially
owned by such person, and (iv) such other information relating to such person as
is required to be disclosed in solicitations of proxies for election of
Directors, or as otherwise required, in each case pursuant to Regulation 14A
under the Securities Exchange Act of 1934, as amended and any successor to such
Regulation; and (b) as to the stockholder giving the notice (i) the name and
address, as they appear on the Corporation's books, of such stockholder, (ii)
the class and number of shares of stock of the Corporation that are beneficially
owned by such stockholder, and (iii) a representation that the stockholder is a
holder of record of stock of the Corporation entitled to vote at such meeting
and intends to appear in person or by proxy at the meeting to nominate the
person or persons specified in the notice. The Corporation may require any
proposed nominee to furnish such other information as may reasonably be required
by the Corporation to determine the eligibility of such proposed nominee to
serve as a Director of the Corporation or the stockholder to nominate the
proposed nominee. No persons shall be eligible for election as a Director of the
Corporation unless nominated in accordance with the procedures set forth herein
and in the

                                        5

Corporation's Certificate of Incorporation. The Chairman of any meeting shall,
if the facts so warrant, determine and declare to the meeting that a nomination
was not made in accordance with the procedures prescribed in the Corporation's
Certificate of Incorporation and these By-Laws; and if he should so determine,
he shall so declare to the meeting and the defective nomination(s) shall be
disregarded.

     Section 2.    RECORD OWNERSHIP. A record of the name and address of the
holder of each certificate, the number of shares represented thereby, and the
date of issue thereof shall be made on the Corporation's books. The Corporation
shall be entitled to treat the holder of record of any share of stock as the
holder in fact thereof and, accordingly, shall not be bound to recognize any
equitable or other claim to or interest in any share on the part of any other
person, whether or not it shall have express or other notice thereof, except as
required by law.

     Section 3.    TRANSFER OF RECORD OWNERSHIP. Transfers of stock shall be
made on the books of the Corporation only by direction of the person named in
the certificate or his attorney, lawfully constituted in writing, and only upon
the surrender of the certificate therefor and a written assignment of the shares
represented thereby. Whenever any transfer of stock is made for collateral
security, and not absolutely, it shall be so expressed in the entry of the
transfer if, when the certificate is presented to the Corporation for transfer,
both the transferor and transferee request the Corporation to do so.

     Section 4.    LOST, STOLEN, OR DESTROYED CERTIFICATES. A certificate
representing shares of stock of the Corporation shall be issued in place of any
certificate alleged to have been lost,

                                       12
<Page>

stolen or destroyed in such manner and on such terms and conditions as the Board
of Directors may authorize from time to time.

     Section 5.    TRANSFER AGENT, REGISTRAR, AND RULES RESPECTING CERTIFICATES.
The Corporation shall maintain one or more transfer offices or agencies where
stock of the Corporation shall be transferable. The Corporation shall also
maintain one or more registry offices where such stock shall be registered. The
Board of Directors may make such rules and regulations as it deems expedient
concerning the issue, transfer and registration of stock certificates.

     Section 6.    FIXING RECORD DATE FOR DETERMINATION OF STOCKHOLDERS OF
RECORD. The Board of Directors may fix in advance a date as the record date for
the purpose of determining the stockholders entitled to receive notice of or
vote at any meeting of stockholders or any adjournment thereof, or to express
consent to corporate action in writing without a meeting, or to receive payment
of any dividend or other distribution or allotment of any rights, or to exercise
any rights in respect of any change, conversion or exchange of stock, or for the
purpose of any other lawful action. Such record date shall be not more than
sixty nor less than ten days before the date of a meeting of stockholders, nor
more than sixty days prior to any other action requiring such determination of
stockholders. A determination of stockholders entitled to receive notice of or
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.

                       SECURITIES HELD BY THE CORPORATION

     Section 1.    VOTING. Unless the Board of Directors otherwise orders, each

or to execute any consent of stockholders of any corporation in which the
Corporation holds stock, to exercise at such meeting any rights incident to the
ownership of such stock, and to execute on behalf of the Corporation a proxy or
proxies empowering another or others to act as aforesaid. The Board of Directors
may confer like powers upon any other person or persons from time to time.

     Section 2.    GENERAL AUTHORIZATION TO TRANSFER SECURITIES HELD BY THE
CORPORATION.

          (a)  Each of the following officers of the Corporation, namely: the
     Chairman of the Board, the President, any Vice President, the Treasurer,
     and the Secretary, shall be authorized to transfer, convert, endorse, sell,
     assign, set over and deliver any shares of stock, bonds, debentures, notes,
     subscription warrants, stock purchase warrants, evidences of indebtedness,
     or other securities now or hereafter standing in the name of or owned by
     the Corporation, and to execute and deliver under the seal of the
     Corporation any written instruments of assignment and transfer necessary or
     proper to effect the authority hereby conferred.

          (b)  Whenever there is annexed to any executed instrument of
     assignment and transfer, pursuant to and in accordance with the foregoing
     paragraph (a), a certificate of the Secretary or an Assistant Secretary of
     the Corporation holding office at the date of such certificate setting
     forth the provisions hereof and stating that they are in full force and
     effect and setting forth the names of persons who are then officers of the
     Corporation, all persons to whom such instrument and annexed certificate
     thereafter comes shall be entitled, without further inquiry or
     investigation and regardless of the date of such certificate, to assume and
     act in reliance upon the assumption that the shares of stock or other
     securities named in such instrument were theretofore duly and properly
     transferred, endorsed, sold, assigned, set over and delivered by the
     Corporation, and that with respect to such securities the authority of
     these provisions of the By-Laws and of such officers is still in full force
     and effect.

                                   ARTICLE VI

                                    DIVIDENDS

     Section 1.    DECLARATION OF DIVIDENDS. Dividends upon the capital stock of
the Corporation may be blared by the Board of Directors at any regular or
special meeting, in accordance with the provisions of law, and may be paid in
cash, property, or shares of capital stock of the Corporation.

     Section 2. PAYMENT AND RESERVES. Before payment of any dividend, there may
be set aside out of any funds of the Corporation available for dividends such
sum or sums as the Board of

                                       14
<Page>

Directors, in its absolute discretion, shall deem proper as a reserve or
reserves for meeting contingencies, equalizing dividends, repairing or
maintaining any property of the Corporation, or any other purpose that the Board
of Directors shall deem conducive to the best interests of the Corporation, and
the Board of Directors may modify or abolish any such reserve in the manner In
which it was created.

     Section 3.    RECORD DATE. The Board of Directors may fix in advance a date
not more than sixty days prior to the date for payment of any dividend as a
record date for determination of stockholders entitled to receive payment of
such dividend, and in such case such stockholders and only such stockholders as
are stockholders on such date shall be entitled to receive payment of such
dividend, notwithstanding any transfer of any stock on the books of the
Corporation after such record date.

                                   ARTICLE VII

                          INDEMNIFICATION OF DIRECTORS,
                         OFFICERS, EMPLOYEES AND AGENTS

     Section 1.    RIGHT TO INDEMNIFY. The Corporation shall indemnify to the
fullest extent authorized by the Delaware General Corporation Law, as the same
exists or may hereafter be amended, (but, in the case of any such amendment,
only to the extent that such amendment permits the Corporation to provide
broader indemnification rights than such law permitted the Corporation to
provide prior to such amendment) any person who was or is a party or threatened
to be made a party to any threatened, pending or completed action, suit or
proceeding whether civil, criminal, administrative or investigative (whether
brought or conducted by a third party or by or in the right of the Corporation),
by reason of the fact that he is or was a Director or officer of the Corporation
or, while a Director or officer of the Corporation, is or was 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 an
employee benefit plan, against expenses, including attorneys' fees, judgments,
fines, penalties, and amounts paid in settlement actually and reasonably
incurred or suffered by him in connection with such action, suit or proceeding
whether or not the indemnified liability arises or arose from any threatened,
pending or completed action by or on behalf of the Corporation; except, that, no
indemnification shall be provided in connection with any claim, issue or matter
as to which a judgment or other final adjudication thereof shall

                                       15
<Page>

establish that acts of active and deliberate dishonesty committed by any such
person with actual dishonest purpose and intent were material to the cause of
action so adjudicated. The termination of any action, suit or proceeding by
judgment, order, conviction, settlement or upon plea of no contest or its
equivalent shall not, of itself, preclude indemnification under this provision.
Such indemnification provided under this Article shall continue as to a person
who has ceased to be a Director, officer, employee or agent and shall inure to
the benefit of his heirs, executors and administrators.

     Section 2.    PROCEDURE. Any indemnification under Section 1 of this
Article, unless ordered by a court, shall be made by the Corporation only as
authorized in the specific case upon a determination that indemnification of the
Director or officer is proper in whole or in part in the circumstances under the
standard established in Section 1 of this Article. The person seeking
indemnification under Section 1 of this Article shall select one of the
following means for determining his right to indemnification:

          (a)  By a majority vote of a quorum of the Board of Directors
     consisting of Directors not at the time parties to the same or related
     proceedings. If a quorum of such Directors cannot be obtained, by majority
     vote of a committee duly appointed by the Board of Directors and consisting
     solely of two or more Directors not at the time parties to the same or
     related proceedings. Directors who are parties to the same or related
     proceedings may participate in the designation of members of the committee.

          (b)  By independent legal counsel elected by a quorum of the Board of
     Directors or its committee in the manner prescribed in Paragraph (a),
     above, or, if unable to obtain such a quorum or committee, by a majority
     vote of the full Board of Directors, including Directors who are parties to
     the same or related proceedings.

          (c)  By a panel of three arbitrators consisting of one arbitrator
     selected by those Directors entitled under Paragraph (b), above, to select
     independent legal counsel, one arbitrator elected by the person seeking
     indemnification and one arbitrator selected by the two arbitrators
     previously selected.

          (d)  By an affirmative vote of shares of the Corporation's voting
     stock, voting as a single class (excluding shares owned by, or voted under
     the control of, persons who are at the time parties to the same or related

                                       16
<Page>

     proceedings, whether as plaintiffs of defendants or in any other capacity).

          There shall be a rebuttable presumption that the person seeking
indemnification has not engaged in conduct which would disqualify him from
receiving indemnification. The burden of rebutting such presumption by clear and
convincing evidence shall be on the Corporation or such party challenging
indemnification.

     Section 3.    RIGHT OF CLAIMANT TO BRING SUIT. If a claim is not paid in
full by the Corporation within thirty days after final determination of such
claim under Section 2 of this Article, the claimant may at any time thereafter
bring suit against the Corporation to recover the unpaid amount of the claim
and, if successful in whole or in part, the claimant shall be entitled to be
paid also the expense of prosecuting such claim. It shall be a defense to any
such action (other than an action brought to enforce a claim for expenses
incurred in defending any proceeding in advance of its final disposition where
the required undertaking, if any is required, has been tendered to the
Corporation) that the claimant has not met the standards of conduct which make
it permissible under the Delaware General Corporation Law for the Corporation to
indemnify the claimant for the amount claimed, but the burden of proving such
defense shall be on the Corporation. Neither the failure of the Corporation
(including its Board of Directors, independent legal counsel or stockholders) to
have made a determination prior to the commencement of such action that
indemnification of the claimant is proper in the circumstances because he or she
has met the applicable standard of conduct set forth in the Delaware General
Corporation Law, nor an actual determination by the Corporation (including its
Board of Directors, independent legal course or stockholders) that the claimant
has not met such applicable standard of conduct, shall be a defense to the
action or create a presumption that the claimant has not met the applicable
standard of conduct.

     Section 4.    SUPPLEMENT. The Corporation may, but shall not be required
to, supplement the right of indemnification and advance payment under this
Article, by any lawful means, including without limitation by reason of
enumeration, (i) the purchase of insurance on behalf of any one or more of such
persons, whether or not the Corporation would be obligated to indemnify such
person under Section 1 of this Article or otherwise, and (ii) individual or
group indemnification agreements with any one or more of such persons.

     Section 5.    ADVANCE PAYMENTS. Expenses, including attorneys' fees,
incurred in defending a civil or criminal

                                       17
<Page>

action, suit or proceeding shall be paid by the Corporation in advance of the
final disposition of such action, suit or proceeding, upon receipt of an
undertaking by or on behalf of the Director, officer, employer or agent to repay
such amount if it shall ultimately be determined that he or she is not entitled
to be indemnified by the Corporation as to such amounts.

     Section 6.    ADDITIONAL RIGHTS. The indemnification and advance payment
provided by this Article shall be not deemed exclusive of any other right to
which an indemnified person may be entitled under Section 145 of the Delaware
General Corporation Law (or any successor provision) or otherwise applicable
law, or under any agreement, vote of stockholders or Directors or otherwise,
both as to action in his official capacity and as to action in another capacity
while holding such office and shall continue as to a person who has ceased to be
a director, officer, employee or agent and shall inure to the benefit of the
heirs, executors and administrators of such a person.

     Section 7.    CONTINUATION OF INDEMNITY. As used in this Article,
references to "the Corporation" shall include, in addition to the resulting or
surviving Corporation, any constituent Corporation absorbed in a consolidation
or merger which, if its separate existence had continued, would have had power
and authority to indemnify its Directors, officers, employees and agents, so
that any person who is or was a director, officer, employee or agent of such
constituent Corporation, or is or was serving at the request of such constituent
Corporation as a director, officer, employee or agent of another corporation,
partnership, joint venture, trust, or other enterprise, shall stand in the same
position under the provisions of this Article with respect to the resulting or
surviving Corporation as he or she would have with respect to such constituent
Corporation if its separate existence had continued.

     Section 8.    SEVERANCE. To the extent any court of competent jurisdiction
shall determine that the indemnification provided under this Article shall be
invalid as applied to a particular claim, issue or matter, the provisions hereof
shall be deemed amended to allow indemnification to the maximum extent permitted
by law.

     Section 9.    APPLICATION. This Article shall be deemed to be a contract
between the corporation and each previous, current or future Director and
officer of the corporation. The provisions of this Article shall be applicable
to all actions, claims, suits or proceedings, commenced after the adoption
hereof, whether arising from any action taken or failure to act

                                       18
<Page>

before or after such adoption. No amendment, modification or repeal of this
Article shall diminish the rights provided hereby or diminish the right to
indemnification with respect to any claim, issue or matter in any material
respect from any alleged action or failure to act prior to such amendment,
modification or repeal.

                                  ARTICLE VIII

                               GENERAL PROVISIONS

     Section 1.    SIGNATURES OF OFFICERS. All checks or demands for money and
notes of the Corporation shall be signed by such officer or officers or such
other person or persons as the Board of Directors shall designate from time to
time. The signature of any officer upon any of the foregoing instruments may be
a facsimile whenever authorized by the Board of Directors.

     Section 2.    FISCAL YEAR. The fiscal year of the Corporation shall end on
such date as shall be fixed by the Board of Directors.

     Section 3.    SEAL. The corporate seal shall have inscribed thereon the
name of the Corporation, the year of its incorporation, and the words "Corporate
Seal, Delaware", and may be used by causing it or a facsimile thereof to be
impressed, affixed, or in any other manner reproduced.

                                   ARTICLE IX

                       WAIVER OF OR DISPENSING WITH NOTICE

     Whenever any notice of the time, place or purpose of any meeting of
stockholders or the Board of Directors or a committee thereof is required by
law, the Certificate of Incorporation, or these By-Laws to be given to any
person, a waiver thereof in writing, signed by such person entitled to such
notice, whether before or after the holding thereof, or his actual attendance at
the meeting, in person, or, in the case of a stockholder, by his
attorney- in-fact, shall be deemed equivalent to the giving of notice to him. No
notice need be given to any person with whom communication is made unlawful by
any law of the United States or any rule, regulation, proclamation or executive
order issued under any such law.

                              AMENDMENT OF BY-LAWS

     These By-Laws may be amended, restated, changed or repealed by the Board of
Directors, as long as authorized by the Certificate of Incorporation, or by the
vote of a majority of the shares of stock present in person or represented by
proxy and entitled to vote at a meeting of stockholders at which a quorum is
present.
