                                    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 Chief Executive Officer or, if not so
designated, at the principal office of the corporation.

         1.2      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 on a date and at a time
designated by the Board of Directors, the Chairman of the Board or the Chief
Executive Officer (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 Bylaws 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 Chief Executive Officer, 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,
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. Without limiting the manner
by which notice otherwise may be given to stockholders, any notice shall be
effective if given by a form of electronic transmission consented to (in a
manner consistent with the General Corporation Law of the State of Delaware) by
the stockholder to whom the notice is given. 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. If notice is given by electronic transmission, such notice shall be
deemed given at the time specified in Section 232 of the General Corporation Law
of the State of Delaware.

         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. Such list shall be open to the examination of any stockholder,
for any purpose germane to the meeting, for a period of at least 10 days prior
to the meeting: (i) on a reasonably accessible electronic network, provided that
the information required to gain access to such list is provided with notice of
the meeting, or (ii) during ordinary business hours, at the principal place of
business of the corporation. The list shall also be

<PAGE>

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 Bylaws, 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, present by means of remote communication in a
manner, if any, authorized by the Board of Directors in its sole discretion, 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 Bylaws 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. It shall not be necessary to notify any
stockholder of any adjournment of less than 30 days if the time and place of the
adjourned meeting, and the means of remote communication, if any, by which
stockholders and proxyholders may be deemed to be present in person and vote at
such adjourned meeting, are announced at the meeting at which adjournment is
taken, unless after the adjournment a new record date is fixed for the adjourned
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 and a
proportionate vote for each fractional share so held, unless otherwise provided
by law or the Certificate of Incorporation. Each stockholder of record entitled
to vote at a meeting of stockholders may vote in person (including by means of
remote communications, if any, by which stockholders may be deemed to be present
in person and vote at such meeting) or may authorize another person or persons
to vote for such stockholder by a proxy executed or transmitted in a manner
permitted by the General Corporation Law of the State of Delaware by the
stockholder or such stockholder's authorized agent and delivered (including by
electronic transmission) to the Secretary of the corporation. No such proxy
shall be voted upon after three years 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 affirmative 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
Bylaws. When a quorum is present at any meeting, any election by stockholders of
directors shall be determined by a plurality of the votes cast by the
stockholders entitled to vote on the election.

corporation as follows: (x) in the case of an election of directors at an annual
meeting of stockholders, not less than 90 days nor more than 120 days prior to
the first anniversary of the preceding year's annual meeting; provided, however,
that (i) in the case of the annual meeting of stockholders of the corporation to
be held in 2004 or (ii) in the event that the date of the annual meeting in any
other year is advanced by more than 20 days, or delayed by more than 60 days,
from the first anniversary of the preceding year's annual meeting, a
stockholder's notice must be so received not earlier than the 120th day prior to
such annual meeting and not later than the close of business on the later of (A)
the 90th day prior to such annual meeting and (B) the tenth day following the

disclosure of the date of such annual meeting was made, whichever first occurs;
or (y) in the case of an election of directors at a special meeting of
stockholders, not earlier than the 120th day prior to such special meeting and
not later than the close of business on the later of (i) the 90th day prior to
such special meeting and (ii) the tenth day following the day on which notice of

such special meeting was made, whichever first occurs.

         The stockholder's notice to the Secretary shall set forth: (a) as to
each proposed nominee (i) such person's name, age, business address and, if
known, residence address, (ii) such person's principal occupation or employment,
(iii) the class and number of shares of stock of the corporation which are
beneficially owned by such person, and (iv) any other information concerning
such person that must be disclosed as to nominees in proxy solicitations

(the "Exchange Act"); (b) as to the stockholder giving the notice (i) such
stockholder's name and address, as they appear on the corporation's books, (ii)
the class and number of shares of stock of the corporation which are owned,
beneficially and of record, by such stockholder, (iii) a description of all
arrangements or understandings between such stockholder and each proposed
nominee and any other person or persons (including their names) pursuant to
which the nomination(s) are to be made by such stockholder, (iv) a

the meeting to nominate the person(s) named in its notice and (v) a
representation whether the stockholder intends or is part of a group which
intends (a) to deliver a proxy statement and/or form of proxy to holders of at
least the percentage of the corporation's outstanding capital stock required to
elect the nominee and/or (b) otherwise to solicit proxies from stockholders in
support of such nomination; and (c) as to the beneficial owner, if any, on

whose behalf the nomination is being made (i) such beneficial owner's name and
address, (ii) the class and number of shares of stock of the corporation which
are beneficially owned by such beneficial owner, (iii) a description of all

proxy statement and/or form of proxy to holders of at least the percentage of
the corporation's outstanding capital stock requirement to elect the nominee
and/or (b) otherwise to solicit proxies from stockholders in support of such
nomination. In addition, to be effective, the stockholder's notice must be
accompanied by the written consent of the proposed nominee to serve as a
director if elected. The corporation may require any proposed nominee to furnish
such other information as may reasonably be required to determine the
eligibility of such proposed nominee to serve as a director of the corporation.
A stockholder shall not have complied with this Section 1.10(b) if the
stockholder or beneficial owner, if any, on whose behalf the nomination is made
solicited (or is part of a group which solicited) or did not so solicit, as the
case may be, proxies in support of such stockholder's nominee in compliance with
the representations with respect thereto required by this Section 1.10.

                  (c)      The chairman of any meeting shall, if the facts
warrant, determine that a nomination was not made in accordance with the
provisions of this Section 1.10 (including whether the stockholder or beneficial

group which solicited) or did not so solicit, as the case may be, proxies in
support of such stockholder's nominee in compliance with the representations
with respect thereto required by this Section 1.10).

                  (d)      Except as otherwise required by law, nothing in this
Section 1.10 shall obligate the corporation or the Board of Directors to include
in any proxy statement or other stockholder communication distributed on behalf
of the corporation or the Board of Directors information with respect to any
nominee for director submitted by a stockholder.

                  (e)      Notwithstanding the foregoing provisions of this
Section 1.10, if the stockholder (or a qualified representative of the
stockholder) does not appear at the annual or special meeting of stockholders of
the corporation to present a nomination, such nomination shall be disregarded,
notwithstanding that proxies in respect of such vote may have been received by
the corporation.

                  (f)      For purposes of this Section 1.10, "public
disclosure" shall include disclosure in a press release reported by the Dow
Jones New Service, Associated Press or comparable national news service or in a
document publicly filed by the Corporation with the Securities and Exchange
Commission pursuant to Section 13, 14 or 15(d) of the Exchange Act.

         1.11     Notice of Business at Annual Meetings.

                  (a)      At any annual meeting of the stockholders, only such
business shall be conducted as shall have been properly brought before the

brought before the meeting by or at the direction of the Board of Directors, or
(iii) properly brought before the meeting by a stockholder. For business to be
properly brought before an annual meeting by a stockholder, (i) if such business
relates to the nomination of a person for election as a director of the
corporation, the procedures in Section 1.10 must be complied with and (ii) if
such business relates to any other matter, the stockholder must (x) have given
timely notice thereof in writing to the Secretary in accordance with the
procedures set forth in Section 1.11(b) and (y) be a stockholder of record on
the date of the giving of such notice and on the record date for the
determination of stockholders entitled to vote at such annual meeting.

                  (b)      To be timely, a stockholder's notice must be received
in writing by the Secretary at the principal executive offices of the
corporation not less than 90 days nor more than 120 days prior to the first
anniversary of the preceding year's annual meeting; provided, however, that (i)
in the case of the annual meeting of stockholders of the corporation to be held
in 2004 or (ii) in the event that the date of the annual meeting in any other
year is advanced by more than 20 days, or delayed by more than 60 days, from the
first anniversary of the preceding year's annual meeting, a stockholder's notice
must be so received not earlier than the 120th day prior to such annual meeting
and not later than the close of business on the later of (A) the 90th day prior
to such annual meeting and (B) the tenth day following the day on which notice
of the date of such annual meeting was mailed or public disclosure of the date
of such annual meeting was made, whichever first occurs.

         The stockholder's notice to the Secretary shall set forth as to each
matter the stockholder proposes to bring before the annual meeting (i) a brief
description of the business desired to be brought before the annual meeting and
the reasons for conducting such business at the annual meeting, (ii) the name
and address, as they appear on the corporation's books, of the stockholder
proposing such business, and the name and address of the beneficial owner, if
any, on whose behalf the proposal is made, (iii) the class and number of shares
of stock of the corporation which are owned, of record and beneficially, by the
stockholder and beneficial owner, if any, (iv) a description of all arrangements
or understandings between such stockholder or such beneficial owner, if any, and
any other person or persons (including their names) in connection with the
proposal of such business by such stockholder and any material interest of the
stockholder or such beneficial owner, if any, in such business, (v) a
representation that such stockholder intends to appear in person or by proxy at
the annual meeting to bring such business before the meeting and (vi) a
representation whether the stockholder or the beneficial owner, if any, intends
or is part of a group which intends (a) to deliver a proxy statement and/or form
of proxy to holders of at least the percentage of the corporation's outstanding
capital stock required to approve or adopt the proposal and/or (b) otherwise to
solicit proxies from stockholders in support of such proposal. Notwithstanding
anything in these Bylaws to the contrary, no business shall be conducted at any
annual meeting of stockholders except in accordance with the procedures set
forth in this Section 1.11; provided that any stockholder proposal which
complies with Rule 14a-8 of the proxy rules (or any successor provision)
promulgated under the Securities Exchange Act of 1934, as amended, and is to be
included in the corporation's proxy statement for an annual meeting of
stockholders shall be deemed to comply with the requirements of this Section
1.11. A stockholder shall not have complied with this Section 1.11(b) if the
stockholder or beneficial owner, if any, on whose behalf the nomination is made
solicited (or is part of a group which solicited) or did not so solicit, as the
case may be, proxies in support of such stockholder's

nominee in compliance with the representations with respect thereto required by
this Section 1.11.

                  (c)      The chairman of any meeting shall, if the facts
warrant, determine that business was not properly brought before the meeting in
accordance with the provisions of this Section 1.11 (including whether the
stockholder or beneficial owner, if any, on whose behalf the proposal is made
solicited (or is part of a group which solicited) or did not so solicit, as the
case may be, proxies in support of such stockholder's proposal in compliance
with the representation with respect thereto required by this Section 1.11), and
if the chairman should so determine, the chairman shall so declare to the
meeting and such business shall not be brought before the meeting.

                  (d)      Notwithstanding the foregoing provisions of this
Section 1.11, if the stockholder (or a qualified representative of the
stockholder) does not appear at the annual meeting of stockholders of the
corporation to present business, such business shall not be transacted,
notwithstanding that proxies in respect of such vote may have been received by
the corporation.

                  (e)      For purposes of this Section 1.11, "public
disclosure" shall include disclosure in a press release reported by the Dow
Jones New Service, Associated Press or comparable national news service or in a
document publicly filed by the corporation with the Securities and Exchange
Commission pursuant to Section 13, 14 or 15(d) of the Exchange Act.

         1.12     Conduct of Meetings.

                  (a)      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 Chief
Executive Officer, or in the Chief Executive Officer's absence by the President
(if the President shall be a different individual than the Chief Executive
Officer), 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)      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
including, without limitation, such guidelines and procedures as it may deem
appropriate regarding the participation by means of remote communication of
stockholders and proxyholders not physically present at a meeting. 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

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

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

on the day on which the Board of Directors adopts the resolution relating to
such purpose.

law, by the Certificate of Incorporation or by these Bylaws, 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

Assistant Secretary, or a temporary Secretary, as to any action taken by the
stockholders, directors, a committee or any officer or representative of the

of the person or persons may require.
