at such time and place as may be fixed by the Board of Directors and stated in
the notice of the meeting or in a duly executed waiver of notice thereof.
Meetings may be held within or without the State of Delaware.

      SECTION 2. The regular annual meeting of stockholders shall be held on
such date and at such time as shall be designated from time to time by the Board
of Directors and stated in the notice of meeting, at which meetings the
stockholders shall elect by a plurality vote, the Class of Directors whose term
expires at such meeting, and transact such other business as may be properly

                                      -1-

      SECTION 3. Written notice of the annual meeting stating the place, date,

such meeting not less than 10 days before the date of the meeting.

      SECTION 4. The Secretary or an Assistant Secretary shall prepare and make,
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

any stockholder, for any purpose germane to the meeting, during ordinary
business hours, for a period of at least 10 days prior 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 list shall also 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.

      SECTION 5. Special meetings of the stockholders, for any purpose or
purposes, may be called by the Chairman of the Board of Directors, by the Chief
Executive Officer or by the Board of Directors.

      SECTION 6. In the case of special meetings of the stockholders, written or
printed notice of a special meeting stating the place, date, and hour of the
meeting and the purpose or purposes for which the meeting is called, shall be
given not less than 10 days, nor more than 60 days before the date of the
meeting, to each stockholder entitled to vote at such meeting. If mailed, such

addressed to the stockholder at his address as it appears on the records of the

      SECTION 7. Business transacted at any special meeting of stockholders

                                      -2-

      SECTION 8. 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

any meeting of the stockholders, the stockholders entitled to vote thereat,
present in person or represented by proxy, shall have the power to adjourn the
meeting from time to time, 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

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.

      SECTION 9. When a quorum is present at any meeting, the vote of the
holders of a majority of the stock having voting power present in person or
represented by proxy shall decide any question brought before such meeting,
unless the question is one upon which by express provision of the statutes or of
the certificate of incorporation, a different vote is required in which case
such express provision shall govern and control the decision of such question.

      SECTION 10. Each stockholder shall at every meeting of the stockholders be
entitled to one vote in person or by proxy for each share of the capital stock
having voting power held by each stockholder, but no proxy shall be valid after
eleven (11) months from the date of its execution, unless otherwise provided in
the proxy.

      SECTION 11. Whenever the vote of stockholders at a meeting thereof is
required or permitted to be taken for or in connection with any corporate
action, by any provision of the statutes, the meeting and vote of stockholders
may be dispensed with if all the

                                      -3-

stockholders who would have been entitled to vote upon the action of such
meeting were held shall consent in writing to such corporate action being taken,
or if a consent in writing, setting forth the action to be taken, shall be
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.

      SECTION 12. Subject to the provisions of the next Section in this Article
II and Section 2 of Article III, the items of business at each regular annual
meeting of stockholders shall include the following:

            (a)  Ascertainment of quorum.
            (b)  Proof of due notice of meeting.
            (c)  Reports of officers and committees.
            (d)  Unfinished business.
            (e)  New business.
            (f)   Election of Directors.
            (g)  Adjournment.

      SECTION 13. At any meeting of the stockholders, only such business shall
be conducted as shall have been properly brought before the meeting. To be
properly brought before a meeting business must be (a) specified in the notice
of meeting (or any 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. For business to be properly brought before a
stockholders' meeting by a stockholder, the stockholder must have given timely
notice thereof in writing to the secretary. To be timely, a stockholder's

                                      -4-

notice must be received at the principal executive offices of the corporation,
not less than 120 days before the date of the corporation"s proxy statement
released to stockholders in connection with the previous year"s annual meeting.
A stockholder's notice to the Secretary shall set forth as to each matter the
stockholder proposes to bring before the meeting, (a) a brief description of the
business desired to be brought before the meeting and the reasons for conducting
such business at the meeting, (b) the name and address, as they appear on the
corporation's books, of the stockholder proposing such business, (c) the class
and number of shares of the corporation which are beneficially owned by the
stockholder, and (d) any material interest of the stockholder in such business.
Notwithstanding anything in the by-laws to the contrary, no business shall be
conducted at any meeting except in accordance with the procedures set forth in
this Section 13. The Chairman of the meeting shall, if the facts warrant,
determine and declare to the meeting that business was not properly brought
before the meeting and in accordance with the provisions of this Section 13, 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.

                                   ARTICLE III
                                    DIRECTORS

      SECTION 1. The number of Directors of the corporation (exclusive of
Directors to be elected by the holders of any one or more series of Preferred
Stock voting separately as a class or classes) shall not be less than three nor
more than twelve, the exact number of Directors to be determined from time to
time by resolution adopted by the affirmative vote of a majority of the whole
Board of Directors, and such exact number shall be eight until otherwise
determined by resolution adopted by the affirmative vote of a majority of the
whole Board of Directors. As used in these by-laws, the term "whole Board" means
the total number of Directors which the corporation would have if there were no
vacancies.

                                      -5-

The Board of Directors (exclusive of Directors to be elected by the holders of
any one or more series of Preferred Stock voting separately as a class or
classes) shall be divided into three classes, Class I, Class II, Class III,
which shall be nearly equal in number as possible. Each Director shall serve for
a term ending on the date of the third annual meeting following the annual
meeting at which such Director was elected; provided, however, that each initial
Director in Class I shall hold office until the annual meeting of stockholders
in 1984; each initial Director in Class II shall hold office until the annual
meeting of stockholders in 1985; and each initial Director in Class III shall
hold office until the annual meeting of stockholders in 1986.

      SECTION 2. Vacancies and newly created Directorships resulting from any
increase in the number of Directors, may, except as otherwise required by law,
be filled only by the Board of Directors, acting by a majority of the Directors
then in office, although less than a quorum, and any Directors so chosen shall
hold office until the next election of the class for which such Directors shall
have been chosen and until their successors shall be elected and qualified. If
there are no Directors in office, then an election of Directors may be held in
the manner provided by Statute. No decrease in the number of Directors shall
shorten the term of any incumbent Director. Notwithstanding the foregoing, and
except as otherwise required by law, whenever the holders of any one or more
series of Preferred Stock shall have the right, voting separately as a class, to
elect one or more Directors of the corporation, the terms of the Director or
Directors elected by such holders shall expire at the next succeeding annual
meeting of stockholders. Only persons who are nominated in accordance with the
procedures set forth in this Section 2 shall be eligible for election as
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 or by any stockholder of the corporation entitled to vote
for the election of Directors at the meeting who complies with the notice
procedures set forth in this Section 2. Such

                                       -6-

nominations, other than those made by or at the direction of the Board of
Directors, shall be made pursuant to timely notice in writing to the secretary.
To be timely, a stockholder's notice shall be received at the principal
executive offices of the corporation not less than 120 days before the date of
the corporation"s proxy statement released to stockholders in connection with
the previous year"s annual meeting. Such stockholder's notice shall set forth
(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 of such person, (ii) the principal occupation or employment of such
person, (iii) the class and number of shares of the corporation which are
beneficially owned by such person and (iv) any other information relating to
such person that is required to be disclosed in solicitations of proxies for
election of Directors, or is otherwise required, in each case pursuant to
Regulation 14A under the Securities Exchange Act of 1934, as amended (including
without limitation such person's written consent to being named in the proxy
statement as a nominee and to serving as a Director if elected); 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 and (ii) the class and number of
shares of the corporation which are beneficially owned by such stockholder. At
the request of the Board of Directors any person nominated by the Board of
Directors for election as a Director shall furnish to the Secretary that
information required to be set forth in a stockholder's notice of nomination
which pertains to the nominee. No person shall be eligible for election as a
Director unless nominated in accordance with the procedures set forth in this
Section 2. The Chairman of the meeting shall, if the facts warrant, determine
and declare to the meeting that a nomination was not made in accordance with the
procedures prescribed by the by-laws, and if he should so determine, he shall so
declare to the meeting and the defective nomination shall be disregarded.


                                       -7-

      SECTION 3. The business of the corporation shall be managed by its Board
of Directors which may exercise all such powers of the corporation and do all
such lawful acts and things as are not by statute or by the certificate of
incorporation or by these by-laws directed or required to be exercised or done
by the stockholders.

                        MEETING OF THE BOARD OF DIRECTORS

      SECTION 4. REMOVAL. A member of the Board of Directors may be removed by
the stockholders of the corporation only for cause. Any such removal for cause
shall be at a special meeting of stockholders called for such purpose. The vote
of the holders of shares conferring 80% of the total votes of all shares of
capital stock of the corporation voting as a single class shall be necessary to
remove a Director. For purposes of this Section 4, cause for removal shall exist
only if a Director shall have been adjudged by a court of competent jurisdiction
to be guilty of fraud, criminal conduct (other than minor traffic violations),
gross abuse of office amounting to a breach of trust, or similar misconduct, and
no appeal (or further appeal) therefore shall be permitted under applicable law.

      No proposal by a stockholder to remove a Director of the corporation shall
be voted upon at a meeting of stockholders unless, at least 120 days before the
date of the corporation"s proxy statement released to stockholders in connection
with the previous year"s annual meeting, such stockholder shall have delivered
in writing to the Secretary of the corporation (1) notice of such proposal, (2)
a statement of the grounds on which such Director is proposed to be removed, (3)
evidence, reasonably satisfactory to the Secretary of the corporation, of such
stockholder's status as such and of the number of shares of each class of the
capital stock of the corporation beneficially owned by such stockholder, (4) a
list of the names of other beneficial owners of shares of the capital stock of
the corporation, if any, with whom such stockholder is acting in concert, and of
the number of shares of each class of the capital stock of the corporation
beneficially owned by each

                                       -8-

such beneficial owner, and (5) an opinion of counsel, which counsel and the form
and substance of which opinion shall be reasonably satisfactory to the Board of
Directors of the corporation (excluding the Director proposed to be removed), to
the effect that, if adopted at a duly called special meeting of the stockholders
of the corporation by the vote of the holders of shares conferring 80% of the
total votes of all shares of the capital stock of the corporation voting as
single class, such removal would not be in conflict with the laws of the State
of Delaware, the certificate of incorporation of the corporation, or these
by-laws. Within 30 days after such stockholder shall have delivered the
foregoing to the Secretary of the corporation, the Secretary and the Board of
Directors of the corporation shall respectively determine whether the items to
be ruled upon by them are reasonably satisfactory and shall notify such
stockholder in writing of their respective determinations. If such stockholder
fails to submit a required item in the form or within the time indicated, or if
the Secretary or the Board of Directors of the corporation determines that the
items to be ruled upon by them, respectively, as provided above are not
reasonably satisfactory, then such proposal by such stockholder may not be voted
upon by the stockholders of the corporation at such meeting of stockholders.

      Notwithstanding the foregoing, and without limiting the ability of the
Board of Directors as provided by applicable law to declare vacant the position
of a Director on the Board of Directors, if a member of the Board of Directors
has been adjudged by a court of competent jurisdiction to be guilty of fraud,
criminal conduct (other than minor traffic violations), gross abuse of office
amounting to a breach of trust, or similar misconduct, and no appeal (or further
appeal) therefrom is permitted under applicable law, the other Directors then in
office, by unanimous vote, may declare the position occupied by such Director
vacant, and such other Directors may fill such vacancy as provided in Section 2
of this Article III of these by-laws.

                                      -9-

      SECTION 5. The Board of Directors of the corporation may hold meetings,
both regular and special, either within or without the State of Delaware.

      SECTION 6. A regular meeting of the Board of Directors shall be held
immediately after the annual election of Directors in each year, provided a
quorum for such meeting can be obtained and thereafter regular meetings of the
Board of Directors shall be held at such time and places as may be fixed by
resolution of the Board. No notice need be given of any regular meeting of the
Board.

      SECTION 7. Special meetings of the Board may be called by the Chairman of
the Board or the Chief Executive Officer on two (2) days notice to each
Director, either personally or by facsimile, telex or telegram or other similar
immediate electronic transmission methods. Special meetings of the Board may be
called by the Chairman of the Board, or the Chief Executive Officer, or the
Secretary in like manner and on like notice on the prior written request of two
Directors. Notwithstanding the foregoing provisions of this Section 6, notice of
such special meetings may be given by mail, addressed and given in the manner
specified in Section 1, Article IV, provided that such notice is given at least
seven (7) days prior to the day set for such special meeting.

      SECTION 8. At all meetings of the Board a majority of the Directors shall
constitute a quorum for the transaction of business and the act of a majority of
the Directors present at any meeting at which there is a quorum shall be the act
of the Board of Directors. If a quorum shall not be present at any meeting of
the Board of Directors the Directors present thereat may adjourn the meeting
from time to time, without notice other than announcement at the meeting, until
a quorum shall be present.

        SECTION 9. Unless otherwise restricted by the certificate of
incorporation or these by-laws, 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


                                      -10-

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 10. The items of business at each regular meeting of the Board
of Directors shall include the following:

        (a) Submission of an action on minutes of any previous meeting or
            meetings which have not been signed by all the Directors.
        (b) Report of officers and employees.
        (c) Report of committees.
        (d) Unfinished business.
        (e) New business.
        (f) Adjournment.

                             COMMITTEES OF DIRECTORS

      SECTION 11. The Board of Directors may, by resolution passed by a majority
of the whole Board, designate one or more committees, each committee to consist
of two or more 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 any member of such committee or committees, the member or
members thereof present at any meeting and not disqualified from voting, whether
or not he or they 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 or in the by-laws of the corporation, shall
have and may exercise the powers 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

                                      -11-

reference to amending the certificate of incorporation, adopting an agreement of
merger or consolidation, recommending to the stockholders the sale, lease or
exchange of all or substantially all of the corporation's property and assets,
recommending to the stockholders a dissolution of the corporation or a
revocation of a dissolution, or amending the by-laws of the corporation and,
unless the resolution or by-laws expressly so provide, no such committee shall
have the power or authority to declare a dividend or to authorize the issuance
of stock. Such committee or committees shall have such name or names as may be
determined from time to time by resolution adopted by the Board of Directors.
Any action taken by any committee shall be promptly reported to the Board as a
whole for information and review and any action taken within the course and
scope of its authority shall be binding on the corporation.

      SECTION 12. Each committee shall keep regular minutes of its meetings and
shall report the same to the Board of Directors as a whole.

      SECTION 13. The Board committees listed in Exhibit A are designated
initially by the Board of Directors, with the responsibilities set forth or
referred to therein.

                            COMPENSATION OF DIRECTORS

      SECTION 14. The Directors shall be paid their expenses, if any, of
attendance at each meeting of the Board of Directors and committees thereof, and
non-management Directors shall be paid such sums, retainers and fees as may be
fixed from time to time by resolution of the Board of Directors for attending
and performing services in connection with meetings of the Board and committees
thereof. No such payment shall preclude any Director from serving the
corporation in any other capacity or in receiving compensation therefor.
Non-management Directors who are members of special or standing committees shall
be allowed compensation for attending committee meetings.

                                      -12-

                                   ARTICLE IV
                                     NOTICES

      SECTION 1. Whenever, under the provisions of the statutes or of the
certificate of incorporation or of these by-laws, notice is required to be given
to any Director or stockholder, it shall not be construed to require personal
notice, but such notice may be given in writing, by mail addressed to such
Director or stockholder, at his address as it appears on the records of the
corporation, with postage thereon prepaid, and such notice shall be deemed to be
given at the time when the same shall be deposited in the United States mail.
Notice to Directors may also be given personally or by facsimile, telex or
telegram, or other similar immediate electronic transmission methods.

        SECTION 2. Whenever any notice is required to be given under the
provisions of the statutes or of the certificate of incorporation or of these
by-laws, a waiver thereof in writing, signed by the person or persons entitled
to said notice, whether before or after the time stated therein, shall be deemed
equivalent thereto.

                                    ARTICLE V
                                    OFFICERS

of Directors and shall be a Chairman of the Board, a Chief Executive Officer, a
President, a Chief Operating Officer, one or more Vice Presidents, (any of whom
may be designated as Executive Vice President, Senior Vice President, or
otherwise at the discretion of the Board), a Secretary and a Treasurer. The
Board of Directors may also elect one or more Assistant Secretaries and
Assistant Treasurers. Any number of offices may be held by the same person,
except the Chairman of the Board or the President shall not also hold the office
of Secretary.

                                      -13-

      SECTION 2. The Board of Directors at its first meeting after each annual
meeting of stockholders shall elect officers of the corporation.

      SECTION 3. The Board of Directors may elect such other officers and
appoint agents as it shall deem necessary who shall hold their offices for such
term and shall exercise such powers and perform such duties as shall be
determined from time to time by the Board.

      SECTION 4. The salaries of all officers of the corporation shall be fixed
by the Board of Directors.

      SECTION 5. The officers of the corporation shall hold office from the date
of election thereto until the first meeting of the Board of Directors after the
next annual meeting of the stockholders and until their successors are elected

Director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise in which it owns shares of capital stock or
other interests or which it is a creditor, against any expenses and costs,
including, but not limited to, legal and accounting fees, judgments, fines and
amounts paid in settlement actually and reasonably incurred by such person in

reasonable cause to believe his conduct was unlawful; provided that no
indemnification shall be made to any such person who is adjudged in such action,

settlement, conviction or upon a plea of NOLO CONTENDERE or its equivalent,

proceeding, or (ii) upon the written opinion of independent legal counsel
requested by the Board of Directors, or (iii) by the stockholders of the
corporation.

civil or criminal action, suit or proceeding may be paid by the corporation to
such person in advance of the final disposition of such action, suit or
proceeding upon receipt of an undertaking by or on behalf of such person to
repay such amount in the event that it shall ultimately be determined that he is
not entitled to indemnification by the corporation as authorized by these
by-laws. Such expenses incurred by other employees and agents may be so paid
upon such terms and conditions, if any, as the Board of Directors deems
appropriate.

of the stockholders or disinterested Directors or otherwise, whether as to
action taken in his official capacity or as to action in any other capacity

liability asserted against him and incurred by him in any such capacity, or
