ballots shall be counted by an inspector or inspectors appointed by the chairman
of the meeting.

total number of authorized directors (whether or not there exist any vacancies
in



                                     - 4 -


previously authorized directorships at the time any such resolution is presented
to the Board of Directors for adoption). Each director shall hold office until
his successor is elected and qualified or until his earlier death, resignation,
retirement, disqualification or removal. Directors will be elected for a term
that will expire at the annual meeting of the stockholders immediately
succeeding their election.

      Section 2.2  Vacancies and Newly Created Directorships. Newly created
directorships resulting from any increase in the authorized number of directors
or any vacancies in the Board of Directors resulting from death, resignation,
retirement, disqualification, or other cause (other than removal from office by
a vote of the stockholders) may be filled only by a majority vote of the
directors then in office. Directors so chosen shall hold office for a term
expiring at the next annual meeting of stockholders. No decrease in the number
of directors constituting the Board of Directors shall shorten the term of any
incumbent director.

      Section 2.3  Removal. Subject to the limitations stated in the Certificate
of Incorporation, any director, or the entire Board of Directors, may be removed

of the holders of at least a majority of the voting power of all, of the
then-outstanding shares of stock of the Corporation entitled to vote generally
in the election of directors, voting together as a single class. Vacancies in
the Board of Directors resulting from such removal may be filled by a majority
of the directors remaining, even though less than a quorum of the Board of
Directors, or by the sole remaining director. If such vacancy was caused by an
action of the stockholders, the vacancy shall be filled by the affirmative vote
of the holders of at least a majority of the total voting power of the then
outstanding voting stock. Directors so chosen shall hold office until a
successor shall be elected and qualified and, if the Board of Directors at such
time is classified, until the next election of the class for which such director
shall have been chosen. No decrease in the number of Directors shall shorten the
term of any incumbent director.

      Section 2.4  Regular Meetings. Regular meetings of the Board of Directors
shall be held at such place or places, within or without the State of Delaware,

regular meeting shall not be required.

      Section 2.5  Special Meetings. Special meetings of the Board of Directors
may be called by any member of the directors then in office, by the Chairman of
the Board, or by the Chief Executive Officer and shall be held at such place,

shall fix. Notice of the place, date, and time of each such special meeting
shall be given to each director by whom it is not waived by mailing written
notice not less than five (5) days before the meeting (one (1) day before the
meeting if delivered by an overnight courier service and two (2) days before the
meeting if by overseas courier service) or by telephoning, telecopying,
telegraphing or personally delivering the same not less than twenty-four (24)

of the total number of authorized directors then in office shall constitute a
quorum for all purposes. If a



                                     - 5 -


quorum shall fail to attend any meeting, a majority of those present may adjourn
the meeting to another place, date, or time, without further notice or waiver
thereof.

      Section 2.7  Participation in Meetings by Conference Telephone. Members of
the Board of Directors, or of any committee of the Board of Directors, may
participate in a meeting of such Board or 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.

      Section 2.8  Conduct of Business. At any meeting of the Board of
Directors, business shall be transacted in such order and manner as the Board
may from time to time determine, and all matters shall be determined by the vote
of a majority of the directors present, except as otherwise provided herein or
required by law. Action may be taken by the Board of Directors without a meeting
if all members thereof consent thereto in writing, and the writing or writings
are filed with the minutes of proceedings of the Board of Directors.

restricted by the Certificate of Incorporation of the Corporation or required by
law, exercise all such powers and do all such acts and things as may be

      Section 3.1  Committees of the Board of Directors. The Board of Directors,
by a vote of a majority of the whole Board, may from time to time designate
committees of the Board, with such lawfully delegable powers and duties as it

committees and any others provided for herein, elect a director or directors to
serve as the member or members, designating, if it desires, other directors as
alternate members who may replace any absent or disqualified member at any
meeting of the committee. Any committee so designated may exercise the power and
authority of the Board of Directors to declare a dividend, to authorize the
issuance of stock or to adopt an agreement of merger or consolidation if the
resolution which designates the committee or a, supplemental resolution of the
Board of Directors shall so provide. In the absence or disqualification of any

vote appoint another member of the Board of Directors to act at the meeting in
the place of the absent or disqualified member.

Adequate provision shall be made for notice to members of all meetings; one
third of the authorized members shall constitute a quorum unless the committee
shall consist of one or two members, in which event one member shall constitute
a quorum; and all matters shall be determined by a majority vote of the members
present. Action may be taken by any committee without a meeting if all members
thereof consent thereto in writing, and the writing or writings are filed with
the minutes of the proceedings of such committee.

                                  ARTICLE VIII
                    INDEMNIFICATION OF DIRECTORS AND OFFICERS

      Section 8.1  Right to Indemnification. Each person who was or is made a
party or is threatened to be made a party to or is' involved in any action, suit
or proceeding, whether civil, criminal, administrative or investigative ("
proceeding"), by reason of the fact that he or she or a person of whom he or she
is the legal representative, is or was a director or officer of the Corporation
or is or was serving at the request of the Corporation as a director or officer
of another corporation; or as a controlling person of a partnership, joint
venture, trust or other enterprise, including service with respect to employee
benefit plans, whether the basis of such proceeding is alleged action in an
official capacity as a director, officer or employee or in any other capacity
while serving as a director or officer, shall be indemnified and held harmless
by the Corporation to the fullest extent authorized by the Delaware General
Corporation Law, as the same exists or may hereafter be amended (but, in the
case of any such amendment, only to the extent that such amendment permits the
Corporation to provide broader indemnification rights than said Law permitted
the Corporation to provide prior to such amendment) against all expenses,
liability and loss reasonably incurred or suffered by such person in connection
therewith and such indemnification shall continue as to a person who has ceased
to be a director



                                     - 11 -


or officer and shall inure to the benefit of his or her heirs, executors and
administrators; provided, however, that, except as provided in Section 8.2, the
Corporation shall indemnify any such person seeking indemnity in connection with
an action, suit or proceeding (or part thereof) initiated by such person only if
(i) such indemnification is expressly required to be made by law, (ii) the
action, suit or proceeding (or part thereof) was authorized by the Board of
Directors of the Corporation, (iii) such indemnification is provided by the
Corporation, in its sole discretion, pursuant to the powers vested in the
Corporation under the Delaware General Corporation Law, or (iv) the action, suit
or proceeding (or part thereof) is brought to establish or enforce a right to
indemnification under an indemnity agreement or any other statute or law or
otherwise as required under Section 145 of the Delaware General Corporation Law.
The rights hereunder shall be contract rights and shall include the right to be
paid by the Corporation expenses incurred in defending any such proceeding in
advance of its final disposition; provided, however, that, if the Delaware
General Corporation Law then so requires, the payment of such expenses incurred
by a director or officer of the Corporation in his or her capacity as a director
or officer (and not in any other capacity in which service was or is rendered by
such person while a director or officer, including, without limitation, service
to an employee benefit plan) in advance of the final disposition of such
proceeding, shall be made only upon delivery to the Corporation of an
undertaking, by or on behalf of such director or officer, to repay all amounts
so advanced if it should be determined ultimately that such director or officer
is not entitled to be indemnified under this Section or otherwise.

      Section 8.2  Right of Claimant to Bring Suit. If a claim under Section 8.1
is not paid in full by the Corporation within thirty (30) days after a written
claim has been received by the Corporation, the claimant may at any time
thereafter bring suit against the Corporation to recover the unpaid amount of
the claim and, if such suit is not frivolous or brought in bad faith, the
claimant shall be entitled to be paid also the expense of prosecuting such
claim. It shall be a defense to any such action (other than an action brought to
enforce a claim for expenses incurred in defending any proceeding in advance of
its final disposition where the required undertaking, if any, has been tendered
to this Corporation) that the claimant has not met the standards of conduct
which make it permissible under the Delaware General Corporation Law for the
Corporation to indemnify the claimant for the amount claimed, but the burden of
proving such defense shall be on the Corporation. Neither the failure of the
Corporation (including its Board of Directors, independent legal counsel, or its
stockholders) to have made a determination prior to the commencement of such
action that indemnification of the claimant is proper in the circumstances
because he or she has met the applicable standard of conduct set forth in the
Delaware General Corporation Law, nor an actual determination by the Corporation
(including its Board of Directors, independent legal counsel, or its
stockholders) that the claimant has not met such applicable standard of conduct,
shall be a defense to the action or create a presumption that a claimant has not
met such applicable standard of conduct.

      Section 8.3  Non Exclusivity of Rights. The rights conferred on any person
by Sections 8.1 and 8.2 shall not be exclusive of any other right which such
persons may have or hereafter acquire under any statute, provision of the
Certificate of Incorporation, bylaw, agreement, vote of stockholders or
disinterested directors or otherwise.

      Section 8.4  Indemnification Contracts. The Board of Directors is
authorized to enter into a contract with any director, officer, employee or
agent of the Corporation, or any person



                                     - 12 -


serving at the request of the Corporation as a director, officer, employee or
agent of another corporation, partnership, joint venture, trust or other
enterprise, including employee benefit plans, providing for indemnification
rights equivalent to or, if the Board of Directors so determines, greater than,
those provided for in this Article VIII.

      Section 8.5  Insurance. The Corporation may maintain insurance to the
extent reasonably available, at its expense, to protect itself and any such
director, officer, employee or agent of the Corporation or another corporation,
partnership, joint venture, trust or other enterprise against any such expense,
liability or loss, whether or not the Corporation would have the power to
indemnify such person against such expense, liability or loss under Delaware
General Corporation Law.

      Section 8.6  Effect of Amendment. Any amendment, repeal or modification of
any provision of this Article VIII by the stockholders or the directors of the
Corporation shall not adversely affect any right or protection of a director or
officer of the Corporation existing at the time of such amendment, repeal or
modification.


                                   ARTICLE IX
                                   AMENDMENTS

Corporation, the Board of Directors is expressly empowered to adopt, amend or
repeal by-laws of the Corporation, subject to the right of the stockholders to
adopt, amend, alter or repeal the by-laws of the Corporation. Except as
expressly restricted in the Certificate of Incorporation of the Corporation, any
adoption, amendment or repeal of by-laws of the Corporation by the Board of
Directors shall require the approval of a majority of the total number of
authorized directors (whether or not there exist any vacancies in previously
authorized directorships at the time any resolution providing for adoption,
amendment or repeal is presented to the Board). Except as expressly restricted
in the Certificate of Incorporation of the Corporation, the stockholders shall
also have power to adopt, amend or repeal the by-laws of the Corporation.
