Corporation's Restated Certificate of Incorporation (the "Effective Time"), the
Board of Directors shall be divided into three classes to be designated as Class
I, Class II and Class III. The Board of Directors, by resolution, shall

upon such classification. The terms of office of the classes of directors so
designated by the Board of Directors shall expire at the times of the annual
meetings of the stockholders as follows: Class I on the first annual meeting of
stockholders following the Effective Time, Class II on the second annual meeting
following the Effective Time and Class III on the third annual meeting following
the Effective Time, or thereafter in each case when their respective successors
are elected and qualified. At each subsequent annual election, the directors
chosen to succeed those whose terms are expiring shall be identified as being of
the same class as the directors whom they succeed, and shall be elected for a
term expiring at the time of the third succeeding annual meeting of
stockholders, or thereafter in each case when their respective successors are
elected and qualified. The number of directorships shall be apportioned among
the classes so as to maintain the classes as nearly equal in number as possible.

                  SECTION 3.4. VACANCIES. Vacancies, however resulting, and
newly created directorships resulting from any increase in the authorized number
of directors may be filled by a majority of the directors then in office,
although less than a quorum, or by a sole remaining director. Any director

for a term that shall coincide with the term of the class to which such director
shall have been elected.

                  SECTION 3.5. REMOVAL. Subject to any rights of the holders of
any series of Preferred Stock to elect additional directors under specified
circumstances, any director, or the entire Board of Directors, may be removed
from office at any time, but only for cause and only by the affirmative vote of
the holders of at least eighty percent (80%) of the outstanding stock entitled
to vote thereon.

facsimile transmission. If mailed, such notice shall be deemed adequately
delivered when deposited in the United States mails so addressed, with postage

telephone, the notice shall be given at least twelve hours prior to the time set

adequately delivered if transmitted at least twenty-four hours before such
meeting. Neither the business to be transacted at, nor the purpose of, any
regular or special meeting of the Board of Directors need be specified in the
notice of such meeting, except for amendments to these By-laws as provided under
Article IX hereof. A meeting of the Board of Directors may be held at any time
without notice if all the directors are present or if those not present waive
notice of the meeting in writing, either before or after such meeting.

                  SECTION 3.10. WAIVER OF NOTICE. A written waiver, signed by
the director, whether before or after the meeting of the Board of Directors,
shall be equivalent to the giving of such notice. Attendance by a director,

constitute waiver of notice of such meeting.

                  SECTION 3.11. TELEPHONE PARTICIPATION. Directors may

telephone or similar communications equipment if all persons participating in

of Directors shall constitute a quorum for the transaction of business. The vote
of the majority of the directors present at a meeting at which a quorum is

number is required by statute, the Restated Certificate of Incorporation, or
these By-laws.

                  SECTION 3.13. ACTION WITHOUT A MEETING. Any action that may be
taken at a meeting of the directors may be taken without a meeting if a consent
in writing, setting forth the action taken, is signed by all directors.

                  SECTION 3.14. COMPENSATION. By resolution of the Board of
Directors, a director may be paid a fixed sum, and any expenses, for attendance
at a meeting of the Board of Directors. No such payment shall preclude a
director from receiving compensation for serving the Corporation in any other
capacity.

                  SECTION 8.1. NON-DERIVATIVE SUITS. The Corporation shall
indemnify any person who was or is a party or is threatened to be made a party
to any threatened, pending or complete 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 or other enterprise,
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 and 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 the 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 his conduct was unlawful.

                  SECTION 8.2. DERIVATIVE SUITS. The Corporation shall indemnify
any person who was or is a party or is threatened to be made a party to any
threatened, pending or completed action or suit 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 or other
enterprise against expenses (including attorneys' fees) actually and reasonably
incurred by him in connection with the defense or settlement of such action or
suit if he acted in good faith and in a manner he reasonably believed to be in
or not opposed to the best interest of the Corporation and except 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 the Court of Chancery or the court in which
such action or suit was brought shall determine upon application that, despite
the adjudication of liability but in view of all the circumstances of the case,
such person is fairly and reasonably entitled to indemnity for such expenses
which the Court of Chancery or such other court shall deem proper.

                  SECTION 8.3. EXTENT OF INDEMNIFICATION. 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 Section 8.1 or 8.2 above, or in defense of any claim, issue or matter
therein, he shall be indemnified against expenses (including attorneys' fees)
actually and reasonably incurred by him in connection therewith.

                  SECTION 8.4. APPROVAL OF INDEMNIFICATION. Any indemnification
under Section 8.1 or 8.2 above (unless ordered by a court) shall be made 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
Section 8.1 or 8.2 above. Such determination shall be made (1) by the Board of
Directors by a majority vote of a quorum consisting of directors who were not
parties to such action, suit or proceeding, (2) if such a quorum is not
obtainable, or, even if obtainable, a quorum of disinterested directors so
directs, by independent legal counsel in a written opinion or (3) by the
affirmative vote of the holders of a majority of the outstanding shares of
Common Stock of the Corporation.

                  SECTION 8.5. ADVANCES. Expenses (including attorneys' fees)
incurred in defending a civil, criminal, administrative or investigative action,
suit or proceeding shall be paid by the Corporation in advance of the final
disposition of such action, suit or proceeding upon receipt of an undertaking by
or on behalf of the director, officer, employee or agent to repay such amount,
if it shall ultimately be determined that he is not entitled to be indemnified
by the Corporation as authorized in this Article VIII.

                  SECTION 8.6. NON-EXCLUSIVITY. The indemnification and
advancement of expenses provided by, or granted pursuant to, this Article VIII
shall not be deemed exclusive of any other rights to which any person seeking
indemnification may be entitled under any By-law, agreement, vote of
stockholders or disinterested director or otherwise, both as to action in his
official capacity and as to action in another capacity while holding such
office, and shall continue as to a person who has ceased to be a director,
officer, employee or agent and shall inure to the benefit of the heirs,
executors and administrators of such person.

                  SECTION 8.7. INSURANCE. The Corporation shall have power to
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 director, officer, employee or agent of
another corporation, partnership, joint venture, trust or other enterprise
against any liability asserted against him and incurred by him in any such
capacity or arising out of his status as such, whether or not the Corporation
would have the power to indemnify him against such liability under the
provisions of this Section 8.7 or under the provisions of any applicable law or
regulation.

                                   ARTICLE IX.

                  SECTION 9.1. These By-laws may be repealed, altered, amended
or rescinded and new by-laws may be adopted by the majority vote of the Board of
Directors or by the affirmative vote of sixty-six and two-thirds percent
(66-2/3%) of the outstanding stock entitled to vote thereon; provided, however
that Sections 3.2, 3.3, 3.4 and 3.5 may only be repealed, altered, amended or
rescinded by the affirmative vote of eighty percent (80%) of the outstanding
stock entitled to vote thereon.
