                            MEETINGS OF STOCKHOLDERS


      2.1   PLACE OF MEETINGS

      Meetings of stockholders shall be held at any place, within or outside the
State of Delaware, designated by the person or persons calling the meetings. In
the absence of any such designation, stockholders' meetings shall be held at the
registered office of the corporation.

      2.2   ANNUAL MEETING

      The annual meeting of stockholders shall be held each year at such date,
time and place, either within or without the State of Delaware, as may be
designated by resolution of the board of directors from time to time. At the
meeting, directors shall be elected and any other proper business may be
transacted.


                                       1

      2.3   SPECIAL MEETING

      A special meeting of the stockholders may be called at any time by the
board of directors, the chairman of the board, the president or one or more
stockholders holding shares in the aggregate entitled to cast not less than
twenty percent of the votes at the meeting.

      If a special meeting is called by any person or persons other than the
board of directors, the president or the chairman of the board, the request
shall be in writing, specifying the time of such meeting and the general nature
of the business proposed to be transacted, and shall be delivered personally or
sent by registered mail or by telegraphic or other facsimile transmission to the
chairman of the board, the president, any vice president, or the secretary of
the corporation. No business may be transacted at such special meeting otherwise
than specified in such notice. The officer receiving the request shall cause
notice to be promptly given to the stockholders entitled to vote, in accordance
with the provisions of Sections 2.4 and 2.5 of this Article II, that a meeting
will be held at the time requested by the person or persons calling the meeting,
not less than ten (10) nor more than sixty (60) days after the receipt of the
request. If the notice is not given within twenty (20) days after the receipt of
the request, the person or persons requesting the meeting may give the notice.
Nothing contained in this paragraph of this Section 2.3 shall be construed as
limiting, fixing, or affecting the time when a meeting of stockholders called by
action of the board of directors may be held.

      2.4   NOTICE OF STOCKHOLDERS' MEETINGS

      All notices of meetings with stockholders shall be in writing and shall be
sent or otherwise given in accordance with Section 2.5 of these bylaws not less
than ten (10) nor more than sixty (60) days before the date of the meeting to
each stockholder entitled to vote at such meeting. The notice shall specify the
place, date, and hour of the meeting, and, in the case of a special meeting, the
purpose or purposes for which the meeting is called.

      2.5   MANNER OF GIVING NOTICE; AFFIDAVIT OF NOTICE

      Written notice of any meeting of stockholders, if mailed, is given when
deposited in the United States mail, postage prepaid, directed to the
stockholder at his address as it appears on the records of the corporation. An
affidavit of the secretary or an assistant secretary or of 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.


                                       2

      2.6   QUORUM

      The holders of a majority of the stock issued and outstanding and entitled
to vote thereat, present in person or represented by proxy, shall constitute a
quorum at all meetings of the stockholders for the transaction of business
except as otherwise provided by statute or by the certificate of incorporation.
If, however, such quorum is not present or represented at any meeting of the
stockholders, then either (i) the Chairman of the meeting or (ii) the
stockholders entitled to vote thereat, present in person or represented by
proxy, shall have power to adjourn the meeting from time to time, without notice
other than announcement at the meeting, until a quorum is present or
represented. At such adjourned meeting at which a quorum is present or
represented, any business may be transacted that might have been transacted at
the meeting as originally noticed.

      2.7   ADJOURNED MEETING; NOTICE

      When a meeting is adjourned to another time or place, unless these bylaws
otherwise require, notice need not be given of the adjourned meeting if the time
and place thereof are announced at the meeting at which the adjournment is
taken. At the adjourned meeting the corporation may transact any business that
might have been transacted at the original meeting. If the adjournment is for
more than thirty (30) days, or if after the adjournment a new record date is
fixed for the adjourned meeting, a notice of the adjourned meeting shall be
given to each stockholder of record entitled to vote at the meeting.

      2.8   CONDUCT OF BUSINESS

      The Chairman of any meeting of stockholders shall determine the order of
business at the procedure at the meeting, including such regulation of the
manner of voting and the conduct of business.

      2.9   VOTING

      The stockholders entitled to vote at any meeting of stockholders shall be
determined in accordance with the provisions of Section 2.13 of these bylaws,
subject to the provisions of Sections 217 and 218 of the General Corporation Law
of Delaware (relating to voting rights of fiduciaries, pledgors and joint owners
of stock and to voting trusts and other voting agreements).

      Except as may be otherwise provided in the certificate of incorporation,
each stockholder shall be entitled to one vote for each share of capital stock
held by such stockholder.


                                       3

      2.10  WAIVER OF NOTICE

      Whenever notice is required to be given under any provision of the General
Corporation Law of Delaware or of the certificate of incorporation of these
bylaws, a written waiver thereof, signed by the person entitled to notice,
whether before or after the time stated therein, shall be deemed equivalent to
notice. Attendance of a person at a meeting shall constitute a waiver of notice
of such meeting, except when the person attends a meeting for the express
purpose of objecting, at the beginning of the meeting, to the transaction of any
business because the meeting is not lawfully called or convened. Neither the
business to be transacted at, nor the purpose of, any regular or special meeting
of the stockholders need be specified in any written waiver of notice unless so
required by the certificate of incorporation or these bylaws.

      2.11  STOCKHOLDER ACTION BY WRITTEN CONSENT WITHOUT A MEETING

      Unless otherwise provided in the certificate of incorporation, any action
required by this chapter to be taken at any annual or special meeting of
stockholders of the corporation, or any action that may be taken at any annual
or special meeting of such stockholders, 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 thereon were
present and voted.

      Prompt notice of the taking of the corporate action without a meeting by
less than unanimous written consent shall be given to those stockholders who
have not consented in writing. If the action which is consented to is such as
would have required the filing of a certificate under any section of the General
Corporation Law of Delaware if such action had been voted on by stockholders at
a meeting thereof, then the certificate filed under section shall state, in lieu
of any statement required by such section concerning any vote of stockholders,
that written notice and written consent have been given as provided in Section
228 of the General Corporation Law of Delaware.

      2.12  RECORD DATE FOR STOCKHOLDER NOTICE; VOTING; GIVING CONSENTS

      In order that the corporation may determine the stockholders entitled to
notice of or to vote at any meeting of stockholders or any adjournment thereof,
or entitled to express consent to corporate action in writing without a meeting,
or entitled to receive payment of any dividend or other distribution or
allotment of any rights, or entitled to exercise any rights in respect of any
change, conversion


                                       4

or exchange of stock or for the purpose of any other lawful action, the board of
directors may fix, in advance, a record date, which shall not be more than sixty
(60) nor less than ten (10) days before the date of such meeting, nor more than
sixty (60) days prior to any other action.

      If the board of directors does not so fix a record date:

            (i) 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.

            (ii) The record date for determining stockholders entitled to
express consent to corporate action in writing without a meeting, when no prior
action by the board of directors is necessary, shall be the day on which the
first written consent is expressed.

            (iii) 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 thereto.

      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.

      2.13  PROXIES

      Each stockholder entitled to vote at a meeting of stockholders or to
express consent or dissent to corporate action in writing without a meeting may
authorize another person or persons to act for him by a written proxy, signed by
the stockholder and filed with the secretary of the corporation, but no such
proxy shall be voted or acted upon after three (3) years from its date, unless
the proxy provides for a longer period. A proxy shall be deemed signed if the
stockholder's name is placed on the proxy (whether by manual signature,
typewriting, telegraphic transmission or otherwise) by the stockholder or the
stockholder's attorney-in-fact. The revocability of a proxy that states on its
face that it is irrevocable shall be governed by the provisions of Section
212(c) of the General Corporation Law of Delaware.


                                       5

                                   ARTICLE III

                                    DIRECTORS

      3.1   POWERS

      Subject to the provisions of the General Corporation Law of Delaware and
any limitations in the certificate of incorporation or these bylaws relating to
action required to be approved by the stockholders or by the outstanding shares,
the business and affairs of the corporation shall be managed and all corporate
powers shall be exercised by or under the direction of the board of directors.

      3.2   NUMBER OF DIRECTORS

      The board of directors shall consist of at least one (1) person and no
more than ten (10) persons until changed by a proper amendment of this Section
3.2.

      No reduction of the authorized number of directors shall have the effect
of removing any director before that director's term of office expires.

      3.3   ELECTION, QUALIFICATION AND TERM OF OFFICE OF DIRECTORS

      Except as provided in Section 3.4 of these bylaws, directors shall be
elected at each annual meeting of stockholders to hold office until the next
annual meeting. Directors need not be stockholders unless so required by the
certificate of incorporation or these bylaws, wherein other qualifications for
directors may be prescribed. Each director, including a director elected to fill
a vacancy, shall hold office until his successor is elected and qualified or
until his earlier resignation or removal.

      Elections of directors need not be by written ballot.

      3.4   RESIGNATION AND VACANCIES

      Any director may resign at any time upon written notice to the attention
of the Secretary of the corporation. When one or more directors so resigns and
the resignation is effective at a future date, such vacancy, or any vacancy
occurring as a result of a newly created directorship shall be filled in the
following manner, unless otherwise provided in the certificate of incorporation
or these bylaws:

            (i) Vacancies and newly created directorships resulting from any
increase in the authorized number of directors elected by all of the
stockholders having the right to vote may be filled by a majority of the
directors then in office elected by all of the stockholders having a right to
vote, although


                                       6

less than a quorum, or by a sole remaining director, provided, however, that in
the event there remain no directors elected by all of the stockholders having
the right to vote, the holders of the stock of the corporation shall elect a
director or directors to fill such vacancy or newly created directorship in
accordance with the provisions of Article II of these bylaws and the certificate
of incorporation.

            (ii) Whenever the holders of any class or classes of stock or series
thereof are entitled to elect one or more directors by the provisions of the
certificate of incorporation, vacancies and newly created directorships of such
class or classes or series may be filled by a majority of the directors elected
by such class or classes or series thereof then in office, or by a sole
remaining director so elected, provided, however, that in the event there remain
no directors elected by any such class or classes or series, the holders of such
class or classes or series shall elect a director or directors to fill such
vacancy or newly created directorship in accordance with the provisions of
Article II of these bylaws and the certificate of incorporation.

      If at any time, by reason of death or resignation or other cause, the
corporation should have no directors in office, then any officer or any
stockholder or an executor, administrator, trustee or guardian of a stockholder,
or other fiduciary entrusted with like responsibility for the person or estate
of a stockholder, may call a special meeting of stockholders in accordance with
the provisions of Article II of these bylaws and the certificate of
incorporation, or may apply to the Court of Chancery for a decree summarily
ordering an election as provided in Section 211 of the General Corporation Law
of Delaware.

      3.5   PLACE OF MEETINGS; MEETINGS BY TELEPHONE

      The board of directors of the corporation may hold meetings, both regular
and special, either within or outside the State of Delaware.

      Unless otherwise restricted by the certificate of incorporation or these
bylaws, members of the board of directors, or any committee designated by the
board of directors, may participate in a meeting of the board of directors, or
any committee, by means of conference telephone or similar communications
equipment by means of which all persons participating in the meeting can hear
each other, and such participation in a meeting shall constitute presence in
person at the meeting.

      3.6   REGULAR MEETINGS

      Regular meetings of the board of directors may be held without notice at
such time and at such place as shall from time to time be determined by the
board.

      3.7   SPECIAL MEETINGS; NOTICE

      Special meetings of the board of directors for any purpose or purposes may
be called at any time by the chairman of the board, the president, any vice
president, the secretary or any director.

      Notice of the time and place of special meetings shall be delivered
personally or by telephone to each director or sent by first-class mail or
telegram, charges prepaid, addressed to each director at that director's address
as it is shown on the records of the corporation. If the notice is mailed, it
shall be deposited in the United States mail at least four (4) days before the
time of the holding of the meeting. If the notice is delivered personally or by
telephone or by telegram, it shall be delivered personally or by telephone or to
the telegraph company at least forty-eight (48) hours before the time of the
holding of the meeting. Any oral notice given personally or by telephone may be
communicated either to the director or to a person at the office of the director
who the person giving the notice has reason to believe will promptly communicate
it to the director.

      3.8   QUORUM

      At all meetings of the board of directors, a majority of the authorized
number of directors shall constitute a quorum for the transaction of business

                                    CUSTODIAN

      11.1  APPOINTMENT OF A CUSTODIAN IN CERTAIN CASES

      The Court of Chancery, upon application of any stockholder, may appoint
one or more persons to be custodians and, if the corporation is insolvent, to be
receivers, of and for the corporation when:

            (i) at any meeting held for the election of directors the
stockholders are so divided that they have failed to elect successors to
directors whose terms have expired or would have expired upon qualification of
their successors; or

            (ii) the business of the corporation is suffering or is threatened
with irreparable injury because the directors are so divided respecting the
management of the affairs of the corporation that the required vote for action
by the board of directors cannot be obtained and the stockholders are unable to
terminate this division; or


                                       20

            (iii) the corporation has abandoned its business and has failed
within a reasonable time to take steps to dissolve, liquidate or distribute its
assets.

      11.2  DUTIES OF CUSTODIAN

      The custodian shall have all the powers and title of a receiver appointed
under Section 291 of the General Corporation Law of Delaware, but the authority
of the custodian shall be to continue the business of the corporation and not to
liquidate its affairs and distribute its assets, except when the Court of
Chancery otherwise orders and except in cases arising under Sections 226(a)(3)
or 352(a)(2) of the General Corporation Law of Delaware.
