otherwise provided by the Certificate of Incorporation or by statute, each

        Section 2.9  Consents.  The provision of these By-Laws covering notices
                     --------
and meetings to the contrary notwithstanding, any action required or permitted
to be taken at any meeting of stockholders may be taken without a meeting,
without prior notice and without a vote, if a consent in writing setting forth
the action so taken shall be signed by the holders of outstanding stock having
not less than the minimum number of votes that would have been necessary to
authorize or take such action at a meeting at which all shares of stock entitled
to

                                      -4-

vote thereon were present and voted. Where corporate action is taken in such
manner by less than unanimous written consent, prompt written notice of the
taking of such action shall be given to all stockholders who have not consented
in writing thereto and who, if the action had been taken at a meeting, would
have been entitled to notice of the meeting.

          (a)  Actions, Suits or Proceedings Other Than by or in the Right of
               --------------------------------------------------------------
the Corporation.  The Corporation shall indemnify any current or former
     -----------
director or officer of the Corporation and may, at the discretion of the Board,
indemnify any current or former employee or agent of the Corporation who was or
is a party or is threatened to be made a party 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 such person 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 (including trustee) of another
corporation, partnership, joint venture, trust or other enterprise (including
employee benefit plans) (funds paid or required to be paid to any person as a
result of the provisions of this Section 10.1 shall be returned to the
Corporation or reduced, as the case may be, to the extent that such person

suit or proceeding, if he or she acted in good faith and in a manner he or she
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 that his or her 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 seeking indemnification did not act
in good faith and in a manner which he or she 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 that his or
her conduct was unlawful.

          (b)  Actions or Suits by or in the Right of the Corporation.  The
               ------------------------------------------------------

or agent of the Corporation, or is or was serving at the request of the
Corporation as a director, officer, employee or agent (including trustee) of
another corporation, partnership, joint venture, trust or other enterprise
(including employee benefit plans) (funds paid or required to be paid to any
person as a result of the provisions of this Section 10.1 shall be returned to
the Corporation or reduced, as the case may be, to the extent that such person
receives funds pursuant to an indemnification from any such other corporation,
partnership, joint venture, trust or enterprise) to the fullest extent permitted
under Delaware law, as then in

effect, against expenses (including attorneys' fees) actually and reasonably
incurred by such person in connection with the defense or settlement of such
action or suit, if he or she acted in good faith and in a manner he or she
reasonably believed to be in or not opposed to the best interests of the
Corporation, 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 of the State of Delaware 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.

          (c)  Indemnification for Expenses of Successful Party.  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 10.1, or in

under paragraph (a) or (b) of this Section 10.1 (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 such person has met the applicable
standard of conduct set forth in paragraphs (a) and (b) of this Section 10.1.
Such determination shall be made (1) by the Board by a majority vote of the
directors who are not parties to such action, suit or proceeding, even though
less than a quorum or (2) if

                                      -18-

incurred by an officer or director in defending any 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 such director or
officer to repay such amount if it shall ultimately be determined that such
person is not entitled to be indemnified by the Corporation as authorized in
this Section 10.1. Such expenses (including attorneys' fees) incurred by other
employees and agents may be so paid upon such terms and conditions, if any, as
the Board deems appropriate.

          (f)  Other Rights.  The indemnification and advancement of expenses
               ------------
provided by, or granted pursuant to, the other paragraphs of this Section 10.1
shall not be deemed exclusive of any other rights to which those seeking
indemnification or advancement of expenses may be entitled under any By-Law,
agreement, vote of stockholders or disinterested directors or otherwise, both as
to action in an official capacity and as to action in another capacity while
holding such office.

          (g)  Insurance.  By action of the Board, notwithstanding an interest
               ---------
of the directors in the action, the Corporation may purchase and maintain
insurance, in such amounts as the Board deems appropriate, 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 (including trustee) of another corporation, partnership,

                                      -19-
<PAGE>

joint venture, trust or other enterprise (including employee benefit plans),
against any liability asserted against such person and incurred by such person
in any such capacity, or arising out of such person's status as such, whether or
not the Corporation shall have the power to indemnify such person against such
liability under the provisions of this Section 10.l.

          (h)  Continuation of Rights to Indemnification.  The indemnification
               -----------------------------------------
and advancement of expenses provided by, or granted pursuant to, this Section
10.1 shall, unless otherwise provided when authorized or ratified, 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 a
person.

          (i)  Protection of Rights Existing at Time of Repeal or Modification.
               ---------------------------------------------------------------
Any repeal or modification of this Section 10.1 shall not adversely affect any
right or protection of an indemnified person existing at the time of such
repeal or modification.
