any share, right or option is registered as the owner thereof, for all purposes,

the books of account of the Corporation or statements prepared by any of its

the annual meeting of stockholders in 2001; each initial director in Class II
shall hold office until the annual meeting of stockholders in 2002; and each

the remaining directors of the class in which such vacancy occurs or by the
sole remaining director of that class if only one such director remains, or
by the majority vote of the members of the remaining classes if no such
director remains. A director so elected to fill a vacancy shall serve for the
remainder of the then present term of office of the class to which he is
elected.
G. Notwithstanding any of the provisions of this Certificate of

Preferred Stock to elect one or more directors, any director, or the entire
Board of Directors, may be removed from office at any time, but only for cause
and then only by the affirmative vote of the holders of at least 75% of the
votes entitled to be cast in the election of directors. For the purpose of this
paragraph, "cause" shall mean with respect to any particular director a final
judgment of a court of competent jurisdiction holding that such director caused
demonstrable, material harm to the Corporation through bad faith or active and
deliberate dishonesty.
I. Any amendment, alteration or repeal of this Article IX or any
provision hereof shall require the approval of the holders of the shares of the

which it was created.
(c) To make, amend, alter, change, add to or repeal Bylaws for
the Corporation without any action on the part of the

or book or document of the Corporation except as conferred by

for services to the Corporation, including fees for attendance
at meetings of the Board of Directors, of the Executive
Committee, and of other committees, and to determine the
amount of such compensation and fees.
ARTICLE X
A. A director of the Corporation shall not be disqualified by his
office from dealing or contracting with the Corporation either as a vendor,
purchaser or otherwise, nor shall any transaction or contract of the Corporation
be void or voidable by reason of the fact that any director or any firm of which
any director is a member or any corporation of which any director is a
stockholder, officer or director, is in any way interested in such transaction
or contract, provided that such transaction or contract is or shall be
authorized, ratified or approved either (1) by a vote of a majority of a quorum
of the Board of Directors or of the Executive Committee, without including in
such majority or quorum any director so interested or member of a firm so
interested, or a stockholder, officer or director of a corporation so
interested, or (2) by the written consent of the holders of record of a majority
of all the outstanding shares of stock of the Corporation entitled to vote or
the affirmative vote of the holders of a majority of the stock of the
Corporation represented at any meeting at which a quorum is present, nor shall
any director be liable to account to the Corporation for any profits realized by
or from or through any such transaction or contract of the Corporation
authorized, ratified or approved as aforesaid by reason of the fact that he, or
any firm of which he is a member or any corporation of which he is a
stockholder, officer or director was interested in such transaction or contract.
Nothing herein contained shall create liability in the events above described or
prevent the authorization, ratification or approval of such transactions or
contracts in any other manner permitted by law.
B. Any contract, transaction or act of the Corporation or of the
Board of Directors which shall be ratified by the affirmative vote of the
holders of a majority of the stock of the Corporation represented at any
meeting at which a quorum is present and which is called for that purpose,
shall be as valid and binding as though ratified by every stockholder of the
Corporation; provided, however, that any failure of the stockholders to
6
<PAGE>
approve or ratify such contract, transaction or act, when and if submitted,
shall not be deemed in any way to invalidate the same or to deprive the
Corporation, its directors or officers of their right to proceed with such
contract, transaction or action.
ARTICLE XI
A. The affirmative vote of the holders of not less than a majority of
the outstanding voting stock of the Corporation shall be required for the
approval or authorization of any: (i) merger or consolidation of the Corporation
with or into any other corporation; or (ii) sale, lease, exchange or other
disposition of all or substantially all of the assets of the Corporation to or
with any other disposition of all or substantially all of the assets of the
Corporation to or with any other corporation, person or other entity.

provision hereof shall require the approval of the holders of shares of the
Corporation representing at least 75% of the shares then entitled to vote
thereon.

Corporation or its stockholders for monetary damages for breach of fiduciary

duty of loyalty to the Corporation or its stockholders, (ii) for acts or
omissions not in good faith or which involve intentional misconduct or a knowing
violation of law, (iii) under Section 174 of the DGCL, or (iv) for any
transaction from which the Director derived any improper personal benefit. The
foregoing sentence notwithstanding, if the DGCL hereafter is amended to
authorize further limitations of the liability of a director of a corporation,
then a Director of the Corporation, in addition to the circumstances in which a
Director is not personally liable as set forth in the preceding sentence, shall
be held free from liability to the fullest extent permitted by the DGCL as so
amended. Any repeal or modification of the foregoing provisions of this Article
XII by the stockholders of the Corporation shall not adversely affect any right
or protection of a Director of the Corporation existing at the time of such
repeal or modification.
B. Any amendment, alteration or repeal of this Article XII or any
provision hereof shall require the approval of the holders of the shares of the
Corporation representing at least 75% of the shares then entitled to vote
thereon.
