                                    OFFICES

     SECTION 1.01. Registered Office. The registered office shall be in the City
of Wilmington, County of New Castle, State of Delaware.

     SECTION 1.02. Other Offices. The Corporation may also have offices at such
other places both within and without the State of Delaware as the Board of
Directors may from time to time determine or the business of the Corporation may
require.

     SECTION 1.03. Books. The books of the Corporation may be kept within or
without of the State of Delaware as the Board of Directors may from time to time
determine or the business of the Corporation may require.



                                    ARTICLE 2
                            MEETINGS OF STOCKHOLDERS

     SECTION 2.01. Time and Place of Meetings. All meetings of stockholders
shall be held at such place, either within or without the State of Delaware, on
such date and at such time as may be determined from time to time by the Board
of Directors (or the Chairman in the absence of a designation by the Board of
Directors).

     SECTION 2.02. Annual Meetings. Unless directors are elected by written
consent in lieu of an annual meeting as permitted by the General Corporation Law
of the State of Delaware as the same exists or may hereafter be amended
("Delaware Law"), an annual meeting of stockholders, commencing with the year
2000, shall be held for the election of directors and to transact such other
business as may properly be brought before the meeting. Stockholders may,







unless the certificate of incorporation otherwise provides, 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
elected at an annual meeting held at the effective time of such action are
vacant and are filled by such action.

     SECTION 2.03. Special Meetings. Special meetings of stockholders may be
called by the Board of Directors or the Chairman of the Board and shall be
called by the Secretary at the request in writing of holders of record of a
majority of the outstanding capital stock of the Corporation entitled to vote.
Such request shall state the purpose or purposes of the proposed meeting.

     SECTION 2.04. Notice of Meetings and Adjourned Meetings; Waivers of Notice.
(a) Whenever stockholders are required or permitted to take any action at a
meeting, a written notice of the meeting shall be given which shall state 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. Unless otherwise provided
by Delaware Law, such notice shall be given not less than 10 nor more than 60
days before the date of the meeting to each stockholder of record entitled to
vote at such meeting. Unless these bylaws otherwise require, when a meeting is
adjourned to another time or place (whether or not a quorum is present), 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 which might have been
transacted at the original meeting. If the adjournment is for more than 30 days,
or 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.

     (b) A written waiver of any such notice signed by the person entitled
thereto, 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 the 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. Business transacted at any special meeting of stockholders shall be
limited to the purposes stated in the notice.

     SECTION 2.05. Quorum. Unless otherwise provided under the certificate of
incorporation or these bylaws and subject to Delaware Law, the presence, in
person or by proxy, of the holders of a majority of the outstanding capital
stock of the Corporation entitled to vote at a meeting of stockholders shall
constitute a quorum for the transaction of business. If, however, such quorum
shall not be




                                       2




present or represented at any meeting of the stockholders, the stockholders
present in person or represented by proxy shall adjourn the meeting, without
notice other than announcement at the meeting, until a quorum shall be present
or represented. At such adjourned meeting at which a quorum shall be present or
represented any business may be transacted which might have been transacted at
the meeting as originally notified.

     SECTION 2.06. Voting. (a) Unless otherwise provided in the certificate of
incorporation and subject to Delaware Law, each stockholder shall be entitled to
one vote for each outstanding share of capital stock of the Corporation held by
such stockholder. Any share of capital stock of the Corporation held by the
Corporation shall have no voting rights. Unless otherwise provided in Delaware
Law, the certificate of incorporation or these bylaws, the affirmative vote of a
majority of the shares of capital stock of the Corporation present, in person or
by written proxy, at a meeting of stockholders and entitled to vote on the
subject matter shall be the act of the stockholders.

     (b) Each stockholder entitled to vote at a meeting of stockholders or to
express consent or dissent to a corporate action in writing without a meeting
may authorize another person or persons to act for him by written 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.

     SECTION 2.07. Action by Consent. (a) Unless otherwise provided in the
certificate of incorporation, any action required to be taken at any annual or
special meeting of stockholders, or any action which may be taken at any annual
or special meeting of stockholders, may be taken without a meeting, without
prior notice and without a vote, if a consent or consents in writing, setting
forth the action so taken, shall be signed by the holders of outstanding capital
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 and shall be delivered to the Corporation by
delivery to its registered office in Delaware, its principal place of business,
or an officer or agent of the Corporation having custody of the book in which
proceedings of meetings of stockholders are recorded. Delivery made to the
Corporation's registered office shall be by hand or by certified or registered
mail, return receipt requested. 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 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 stockholders to take the action were delivered
to the Corporation as provided in Section 2.07(b).



                                       3


     (b) Every written consent shall bear the date of signature of each
stockholder who signs the consent, and no written consent shall be effective to
take the corporate action referred to therein unless, within 60 days of the
earliest dated consent delivered in the manner required by this section and
Delaware Law to the Corporation, written consents signed by a sufficient number
of holders to take action are delivered to the Corporation by delivery to its
registered office in Delaware, its principal place of business, or an officer or
agent of the Corporation having custody of the book in which proceedings of
meetings of stockholders are recorded. Delivery made to the Corporation's
registered office shall be by hand or by certified or registered mail, return
receipt requested.

     SECTION 2.08. Organization. At each meeting of stockholders, the Chairman
of the Board, if one shall have been elected, or in his absence or if one shall
not have been elected, the director designated by the vote of the majority of
the directors present at such meeting, shall act as chairman of the meeting. The
Secretary (or in his absence or inability to act, the person whom the chairman
of the meeting shall appoint secretary of the meeting) shall act as secretary of
the meeting and keep the minutes thereof.

     SECTION 2.09. Order of Business. The order of business at all meetings of
stockholders shall be as determined by the chairman of the meeting.



                                    ARTICLE 3

or the certificate of incorporation, the business and affairs of the Corporation
shall be managed by or under the direction of the Board of Directors.

     SECTION 3.02. Number, Election and Term of Office. The number of directors
which shall constitute the whole Board shall be fixed from time to time by
resolution of the Board of Directors but shall not be less than three nor more
than nine. The directors shall be elected at the annual meeting of the
stockholders except as provided in Section 2.02 and Section 3.12 herein, and
each director so elected shall hold office until his successor is elected and
qualified or until his earlier death, resignation or removal. Directors need not
be stockholders.

     SECTION 3.03. Quorum and Manner of Acting. Unless the certificate of
incorporation or these bylaws require a greater number, a majority of the total
number of directors shall constitute a quorum for the transaction of business,
and the affirmative vote of a majority of the directors present at meeting at
which a



                                       4




quorum is present shall be the act of the Board of Directors. When a meeting is
adjourned to another time or place (whether or not a quorum is present), 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 Board of Directors may transact any business which might have been
transacted at the original meeting. If a quorum shall not be present at any
meeting of the Board of Directors the directors present thereat shall adjourn
the meeting, from time to time, without notice other than announcement at the
meeting, until a quorum shall be present.

     SECTION 3.04. Time and Place of Meetings. The Board of Directors shall hold
its meetings at such place, either within or without the State of Delaware, and
at such time as may be determined from time to time by the Board of Directors
(or the Chairman in the absence of a determination by the Board of Directors).

     SECTION 3.05. Annual Meeting. The Board of Directors shall meet for the
purpose of organization, the election of officers and the transaction of other
business, as soon as practicable after each annual meeting of stockholders, on
the same day and at the same place where such annual meeting shall be held.
Notice of such meeting need not be given. In the event such annual meeting is
not so held, the annual meeting of the Board of Directors may be held at such
place either within or without the State of Delaware, on such date and at such
time as shall be specified in a notice thereof given as hereinafter provided in
Section 3.07 herein or in a waiver of notice thereof signed by any director who
chooses to waive the requirement of notice.

     SECTION 3.06. Regular Meetings. After the place and time of regular
meetings of the Board of Directors shall have been determined and notice thereof
shall have been once given to each member of the Board of Directors, regular
meetings may be held without further notice being given.

     SECTION 3.07. Special Meetings. Special meetings of the Board of Directors
may be called by the Chairman of the Board or the President and shall be called
by the Chairman of the Board, President or Secretary on the written request of
three directors. Notice of special meetings of the Board of Directors shall be
given to each director at least three days before the date of the meeting in
such manner as is determined by the Board of Directors.

     SECTION 3.08. 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



                                       5



of a committee, the member or members 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,
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; but no such committee shall have the power or authority in
reference to the following matter: (i) approving or adopting, or recommending
to the stockholders, any action or matter expressly required by Delaware Law to
be submitted to the stockholders for approval or (ii) adopting, amending or
repealing any bylaw of the Corporation. Each committee shall keep regular
minutes of its meetings and report the same to the Board of Directors when
required.

     SECTION 3.09. Action by Consent. Unless otherwise restricted by the
certificate of incorporation or these bylaws, 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 thereto in writing, and the writing or writings are filed
with the minutes of proceedings of the Board or committee.

     SECTION 3.10. Telephonic Meetings. 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 such committee, as the case may be, 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.

     SECTION 3.11. Resignation. Any director may resign at any time by giving
written notice to the Board of Directors or to the Secretary of the Corporation.
The resignation of any director shall take effect upon receipt of notice thereof
or at such later time as shall be specified in such notice; and unless otherwise
specified therein, the acceptance of such resignation shall not be necessary to
make it effective.

     SECTION 3.12. Vacancies. Unless otherwise provided in the certificate of
incorporation, vacancies and newly created directorships resulting from any
increase in the authorized number of directors elected by all the stockholders
having the right to vote as a single class may be filled by a majority of the
directors then in office, although less than a quorum, or by a sole remaining
director. Whenever the holders of any class or classes of stock or series
thereof


                                       6



are entitled to elect one or more directors by the certificate of incorporation,
vacancies and newly created directorships of such class or classes or series may
be filled by a majority of directors elected by such class or classes or series
thereof then in office, or by a sole remaining director so elected. Each
director so chosen shall hold office until his successor is elected and
qualified, or until his earlier death, resignation or removal. If there are no
directors in office, then an election of directors may be held in accordance
with Delaware Law. Unless otherwise provided in the certificate of
incorporation, when one or more directors shall resign from the Board, effective
at a future date, a majority of the directors then in office, including those
who have so resigned, shall have the power to fill such vacancy or vacancies,
the vote thereon to take effect when such resignation or resignations shall
become effective, and each director so chosen shall hold office as provided in
the filling of other vacancies.

     SECTION 3.13. Removal. Any director or the entire Board of Directors may be
removed, with or without cause, at any time by the affirmative vote of the
holders of a majority of the outstanding capital stock of the Corporation
entitled to vote and the vacancies thus created may be filled in accordance with
Section 3.12 herein.

     SECTION 3.14. Compensation. Unless otherwise restricted by the certificate
of incorporation or these bylaws, the Board of Directors shall have authority to
fix the compensation of directors, including fees and reimbursement of expenses.

Secretary.

of Directors. Any vacancy in any office shall be filled in such manner as the
Board of Directors shall determine.

     SECTION 4.03. Subordinate Officers. In addition to the principal officers
enumerated in Section 4.01 herein, the Corporation may have one or more
Assistant Treasurers, Assistant Secretaries and Assistant Controllers and such
other subordinate officers, agents and employees as the Board of Directors may
deem necessary, each of whom shall hold office for such period as the Board of
Directors may from time to time determine. The Board of Directors may delegate
to any principal officer the power to appoint and to remove any such subordinate
officers, agents or employees.

     SECTION 4.04. Removal. Except as otherwise permitted with respect to
subordinate officers, any officer may be removed, with or without cause, at any

remove such officer). The resignation of any officer shall take effect upon

                               GENERAL PROVISIONS

     SECTION 5.01. Fixing the Record Date. (a) 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, the Board of Directors may fix a record
date, which record date shall not precede the date upon which the resolution
fixing the record date is adopted by the Board of Directors, and which record
date shall not be more than 60 nor less than 10 days before the date of such

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

of record entitled to notice of or to vote at a meeting of stockholders shall
apply to any adjournment of the meeting; provided that the Board of Directors
may fix a new record date for the adjourned meeting.

     (b) In order that the Corporation may determine the stockholders entitled
to consent to corporate action in writing without a meeting, the Board of
Directors may fix a record date, which record date shall not precede the date
upon which the resolution fixing the record date is adopted by the Board of
Directors, and which date shall not be more than 10 days after the date upon
which the resolution fixing the record date is adopted by the Board of
Directors. If no record date has been fixed by the Board of Directors, the
record date for determining stockholders entitled to consent to corporate action
in writing without a meeting, when no prior action by the Board of Directors is
required by Delaware Law, shall be the first date on which a signed written
consent setting forth the action taken or proposed to be taken is delivered to
the Corporation by delivery to its registered office in Delaware, its principal
place of business, or an officer or agent of the Corporation having custody of
the book in which proceedings of meetings of stockholders are recorded. Delivery
made to the Corporation's registered office shall be by hand or by certified or
registered mail, return receipt requested. If no record date has been fixed by
the Board of Directors and prior action by the Board of Directors is required by
Delaware Law, the record date for determining stockholders entitled to consent
to corporate action in writing without a meeting shall be at the close of
business on the day on which the Board of Directors adopts the resolution taking
such prior action.

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

     SECTION 5.02. Dividends. Subject to limitations contained in Delaware Law
and the certificate of incorporation, the Board of Directors may declare and pay

dividends may be paid either in cash, in property or in shares of the capital
stock of the Corporation.

Directors may authorize any person, on behalf of the Corporation, to attend,
