time to time by resolution adopted by majority vote of the directors then in
office. Directors need not be shareholders. The directors shall be elected
annually. Each director, whether elected at an annual meeting of the
shareholders or to fill a vacancy or a newly created directorship, shall
continue in office until the next annual meeting of the shareholders held after
his election and until his successor shall have been elected and qualified, or

appointed by the chairman of the meeting, shall act as secretary of the meeting.

                                       2



        SECTION 6. Removal. Any director may be removed with or without cause at
any time by the vote of the holders of at least a majority of the shares of
Common Stock at a meeting of the shareholders called for that purpose.

        SECTION 7. Vacancies. In case any vacancy or newly created directorship
shall occur in the Board, the Board may by vote of a majority of the directors

for the unexpired portion of the term or to fill such newly created
directorship.

        SECTION 8. Meetings. The Board may hold meetings either in or outside
the State of Delaware. Regular meetings of the Board may be held, without notice
at such times and places as shall be determined, or with notice in accordance
with the manner established, by resolution of the Board. The next meeting of the
Board following each annual election of directors shall be for the purposes of
organization, election of officers and the transaction of other business.
Special meetings of the Board may be called with notice on the request of the
President, the Chairman of the Board or two (2) other directors. With notice, a
meeting of the Board may be cancelled on the request of the President, the
Chairman of the Board or two (2) other directors. Notices shall be mailed, sent

on the records of the Corporation, or given by telephone, and in the case of
notice of a meeting, on a day not later than the third day before the day on
which the meeting is to be held. Every such notice of a meeting shall state the
time and place fixed by the President, the Chairman of the Board or two (2)
directors, as the case may be, but need not state the purpose or purposes of the
meeting. Any required notice may be waived in writing, signed by the director
entitled thereto, whether before or after the time stated therein, and
attendance at a meeting shall constitute a waiver of notice of such meeting.

        SECTION 9. Quorum; Manner of Acting; Procedure. At any meeting of the
Board, one-third (1/3) of the total number of directors fixed by or pursuant to
these By-Laws, but not less than two (2), shall constitute a quorum for the
transaction of business at such meeting. Common or interested directors may be
counted in determining the presence of a quorum at a meeting of the Board which
authorizes any contract or transaction in which one or more of the directors are
interested or common directors. The vote of a majority of the directors present
at a meeting at which a quorum is present shall be the act of the Board;
provided, however, where permissible by law, the vote of a majority of the
disinterested directors present, even though less than a quorum, shall be the
act of the Board. Directors may participate in a meeting of the Board 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 shall constitute presence in person at such meeting. In the
absence of a quorum, a majority of the directors present may, without notice
other than announcement at the meeting, adjourn the meeting from time to time
until a quorum be had. Any action required or permitted to be taken at any
meeting of the Board may be taken without a meeting if all members of the Board
consent thereto in writing, and the writing or writings are filed with the
minutes of proceedings of the Board. The directors shall act only as a Board,
and the individual directors shall have no power as such.

        SECTION 10. Remuneration. Each director shall be compensated for
reasonable


                                       3



expenses incurred by him in attending the meetings of the Board. Otherwise, no
director shall receive compensation for acting in his capacity as such, except
as provided by a resolution of the Board.

                                   ARTICLE IV
                                   COMMITTEES

        SECTION 1. How Constituted. The Board of Directors may, by a resolution
adopted by a majority of the Board, elect two (2) or more of its members to
constitute a committee of the Board.

        SECTION 2. Term of Office; Vacancies. Each member of a committee shall
continue in office until the next annual meeting of the Board after his
election, or until his earlier resignation or removal. In case any vacancy shall
occur in a committee resulting from any cause whatsoever, such vacancy may be
filled by vote of a majority of the Board, at any regular or special meeting.

        SECTION 3. Meetings. Regular meetings of a committee may be held without
notice at such times and places in or outside Delaware, as shall be determined,
or with notice in accordance with the manner established, by resolution of the
Board or the committee. Special meetings of a committee may be held at such
times and at such places as shall be specified in a notice by the Chairman,
Secretary or any member of the committee. Notices shall be mailed, sent by
telegraph or delivered personally to each member of the committee at his address
appearing on the records of the Corporation, or given by telephone at least
twenty-four (24) hours before the meeting. Every such notice of a meeting shall
state the time and place fixed for, but need not state the purpose or purposes
of, the meeting. Any required notice may be waived in writing, signed by the
member entitled thereto, whether before or after the time stated therein, and
attendance at a meeting shall constitute a waiver of notice of such meeting.

        SECTION 4. Quorum; Manner of Acting; Procedure. A majority of the
members of a committee shall constitute a quorum for the transaction of business
at any meeting thereof. The vote of a majority of the members present at any
meeting at which a quorum is present shall be the act of the committee. In the
absence of a quorum, a majority of the members present may, without notice other
than announcement at the meeting, adjourn the meeting from time to time until a
quorum be had. The committee shall elect from among its members a chairman who
shall act as chairman of the meetings of the committee. In his absence at
meetings of the committee, a member of the committee chosen by the members
thereof present shall act as chairman of the meeting. A secretary, appointed by
the committee, shall keep a record of each meeting and file a copy of that
record with the records of the Corporation. Members of a committee may
participate in a meeting of the 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 shall constitute
presence in person at such meeting. Any action required or permitted to be taken
at any meeting of the committee may be taken without a meeting if all members of
the committee consent thereto in writing, and the writing or writings are filed
with the minutes


                                       4



of proceedings of the committee. The members shall act only as the committee,
and the individual directors shall have no power as such.

        SECTION 5. Removal and Resignations. Any member of a committee may be
removed from the committee at any time, with or without cause, by a resolution
adopted by a majority of the full Board. Removal from the Board shall also
constitute removal from the committee. Any member of a committee may resign from
the committee at any time upon written notice and such resignation shall be
effective, unless otherwise agreed, upon receipt by the chairman of the
committee or the Secretary of the Corporation. Resignation from the Board shall
also constitute resignation from the committee.

        SECTION 6. Powers and Authority. To the extent provided by resolution of
the Board from time to time, any committee of the Board, upon proper
constitution, shall have and may exercise all of the powers and authority of the
Board in the direction of the management of the business and affairs of the
Corporation, including the power and authority to declare a dividend, to
authorize the issuance of stock and to authorize the seal of the Corporation to
be affixed to all papers which may require it; provided, however, that no such
committee shall have the power or authority to amend the Certificate of
Incorporation, amend these By-Laws, adopt an agreement of merger or
consolidation, recommend to the shareholders the sale or lease or exchange of
all or substantially all of the Corporation's property and assets, or recommend
to the shareholders a dissolution of the Corporation or a revocation of a
dissolution.

continue in office until his successor shall have been duly elected or
appointed, or until he shall have resigned and his resignation shall have become
effective, or until he shall have been removed in the manner prescribed by
Section 4 of this Article V. The Board may, by vote of a majority of the
directors then in office, elect a person to fill any vacancy or newly created
office, for the unexpired portion of the term.

        SECTION 3. Additional Officers; Other Officers. The Board may elect
additional officers, each of whom shall have such powers, authority and duties
as may from time to time be delegated by resolution of the Board, the President
or any authorized officer senior to such additional officer, and as are provided
in these By-Laws. The Board may also authorize the President to appoint other
officers of the Corporation.

        SECTION 4. Removal; Resignation. Any officer may be removed, with or
without cause, by the Board at any meeting thereof, or by any committee or
officer upon whom such power of removal may be conferred by the Board, or by any
officer upon whom the power to appoint such officer may have been conferred, Any
officer may resign at any time upon written notice, and such resignation shall
be effective, unless otherwise agreed, upon receipt by the Board, the President,

necessary or appropriate to the conduct or attainment of the Corporation's
business or purposes as are not by law, the Corporation's Certificate of
Incorporation or these By-Laws directed or required to be exercised or done by
the shareholders or by the Board. The President shall preside at all meetings of
the shareholders and, in the absence of the Chairman of the Board, at all
meetings of the Board at which he is present. In general, the President shall
perform all duties incident to the office of the President, and such other
duties as may from time to time be assigned by the Board. The Board may
authorize the President to prescribe in writing powers, authority and duties of
any officers of the Corporation (other than the President), which he may deem
advisable or appropriate, and to authorize any officer of the Corporation to
delegate further in writing, with such limitations as the President or such
delegating officer may deem advisable or appropriate, the powers, authority and
duties delegated to such officer.

        SECTION 7. The Secretary. The Secretary shall perform all of the duties
incident to the office of Secretary and such other duties as may from time to

Corporation, and such authority may be general or confined to specific


                                       6



instances; and unless so authorized, no officer, employee or agent shall have

to pledge its credit or to render it liable pecuniarily for any purpose or to
any amount.

        SECTION 2. Loans. No loan shall be contracted on behalf of the

                                    ARTICLE X
             LIMITATION OF LIABILITY: INDEMNIFICATION AND INSURANCE
                        OF DIRECTORS, OFFICERS AND OTHERS

        SECTION 1. Limitation of Liability. Neither a director of the
Corporation nor a director, officer or employee of the Corporation serving as a
director of another company at the request of the Corporation (hereafter
"Designated Director") shall have any personal


                                       7



liability to the Corporation or its shareholder for monetary damages arising out
of a breach of fiduciary duty in such capacity, except for (i) any breach of the
director's duty of loyalty to the Corporation or its shareholder, or in the case
of a Designated Director, breach of his duty of loyalty to the company of which
he is a director or its shareholders, (ii) any acts or omissions not in good
faith or which involve intentional misconduct or knowing violation of law, (iii)
any unlawful payment of a dividend or other distribution prohibited by Section
174 of the Delaware General Corporation Law, or (iv) any transaction from which
the director or Designated Director derived an improper personal benefit.

        SECTION 2. Indemnification: Insurance and Other Arrangements.

        (a) Actions Other Than Those By or in the Right of the Corporation. The
Corporation shall indemnify, to the full extent not prohibited by law, any
person who was or is a party or is threatened to be made party (including a
witness) to any threatened, pending or completed action, suit or proceeding,
whether civil, criminal, administrative or investigative (other than an action
by or in the right of the Corporation), by reason of the fact that he is or was
a director, officer, employee or agent of the Corporation, or is or was serving
at the request of the Corporation as a director, officer, employee or agent of
another corporation, partnership, joint venture, trust, employee benefit plan or
other enterprise or entity, against expenses (including attorneys' fees),
judgments, fines and amounts paid in settlement, actually and reasonably
incurred by him in connection with such action, suit or proceeding if he acted
in good faith, in a manner he reasonably believed to be in or not opposed to the
best interests of the Corporation, and, with respect to any criminal action or
proceeding, had no reasonable cause to believe his conduct was unlawful. The
termination of any action, suit or proceeding by judgment, order, settlement,
conviction, or upon a plea of nolo contendere or its equivalent, shall not, of
itself, create a presumption that such person did not act in good faith and in a
manner which he reasonably believed to be in or not opposed to the best
interests of the Corporation, and with respect to any criminal action or
proceeding, had reasonable cause to believe that his conduct was unlawful.

        (b) Action By or in the Right of the Corporation. The Corporation shall
indemnify, to the full extent not prohibited by law, any person who was or is a
party or is threatened to be made a party (including a witness) to any
threatened, pending or completed action, suit or proceeding by or in the right
of the Corporation to procure a judgment in its favor by reason of the fact that
he is or was a director, officer, employee or agent of the Corporation, or is or
was serving at the request of the Corporation as a director, officer, employee
or agent of another corporation, partnership, joint venture, trust, employee
benefit plan or other enterprise or entity, against expenses (including
attorneys' fees) actually and reasonably incurred by him in connection with the
defense or settlement of, or appearance connected with, such action, suit or
proceeding if he acted in good faith and in a manner he reasonably believed to
be in or not opposed to the best interests of the Corporation; provided,
however, that no indemnification shall be made in respect of any claim, issue,
or matter as to which such person shall have been adjudged to be liable to the
Corporation unless and only to the extent that a court, upon application, shall
determine that, despite the adjudication of liability but in view of all
circumstances of the case, such person is fairly and reasonably entitled to
indemnification for such expenses.


                                       8



        (c) Successful Defense of Action. Notwithstanding, and without
limitation of, any other provision of this Article X, to the extent that a
director, officer, employee or agent of the Corporation has been successful on
the merits or otherwise in defense of any action, suit or proceeding referred to
in paragraph (a) or (b) of this Section 2, or in defense of any claim, issue or
matter included therein, he shall be indemnified against expenses (including
attorneys' fees) actually and reasonably incurred by him in connection
therewith.

        (d) Determination Required. Any indemnification under paragraph (a) or
(b) of this Section 2 (unless ordered by a court) shall be made promptly by the
Corporation only as authorized in the specific case upon a determination that
indemnification of the director, officer, employee or agent is proper in the
circumstances because he has met the applicable standard of conduct set forth in
such paragraph. Such determination shall be made, in the case of any officer or
director, by a majority vote of the directors who were not parties to the
particular action, suit or proceeding even if those directors constitute less
than a quorum of the Board of Directors, or (ii) there are no such directors, or
if such directors so direct, by legal counsel in a written opinion, or (iii) by
the stockholders. Such determination shall be made, in the case of an employee
or agent of the Corporation who is not an officer or director of the
Corporation, as specified in the preceding sentence or by the President or by
any officer authorized by the President.

        (e) Advance of Expenses. Expenses incurred with respect to any action,
suit or proceeding, whether civil, criminal, administrative or investigative,
specified in paragraph (a) or (b) of this Section 2 of this Article X, shall be
paid promptly by the Corporation in advance of the final disposition of such
action, suit or proceeding upon receipt of a satisfactory undertaking by or on
behalf of the director, officer, employee or agent to repay such amount if it
shall be determined that he is not entitled to be indemnified by the Corporation
as authorized by the Board, in the case of any director or officer, or by the
President or any officer authorized by the President, in the case of any
employee of the Corporation who is not a director or officer, and as authorized
in this Section 2.

        SECTION 3. Insurance. The Corporation shall, when authorized by the
Board, purchase and maintain insurance on behalf of any person who is or was a
director, officer, employee or agent of the Corporation or is or was serving at
the request of the Corporation as a director, officer, employee or agent of
another corporation, partnership, joint venture, trust, employee benefit plan or
other enterprise or entity against any liability asserted against, and incurred
by, him in any such capacity, or arising out of his status as such, whether or
not the Corporation would be required to indemnify him against such liability
under the provisions of Section 2 of this Article X.

        SECTION 4. Nonexclusivity; Duration. The indemnifications, advancement
of expenses and other rights and limitations of liability provided by this
Article X shall not be deemed exclusive of any other indemnifications, rights,
agreements regarding advancement of expenses or limitation of liability to which
any person may be entitled under any statute, certificate of incorporation,
by-law, agreement, vote of shareholders or disinterested directors, or
otherwise, either as to action in his official capacity or as to action in any
other capacity. The authorization to purchase and maintain insurance set forth
in Section 3 of this Article X


                                       9



shall likewise not be deemed exclusive. Such indemnifications, rights and
limitations of liability shall continue although such person has ceased to be a
director, officer, employee or agent and shall inure to the benefit of his
heirs, executors and administrators. No amendment of these By-Laws shall effect
adversely any rights of any person to indemnity, limitation of liability or
advancement of expenses pursuant to these By-Laws, to the extent any matter as
to which indemnity, limitation of liability or advancement of expenses may be
sought arose prior to any such amendment becoming effective.

        SECTION 5. Constituent Corporations. For purposes of this Article X,
references to "the Corporation" shall include, in addition to the resulting
corporation, any constituent corporation (including any constituent of a
constituent) absorbed in a consolidation or merger which, if its separate
existence had continued, would have had power and authority to indemnify its
directors, officers, and employees or 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, employee benefit plan, or other enterprise or entity, shall stand in the
same position under the provisions of this Article X in respect of the resulting
