ARTICLE V.
In furtherance and not in limitation of the powers conferred by
statute, the Bylaws of the Corporation may be made, altered, amended or repealed

ARTICLE VI.
(a) The business and affairs of the Corporation shall be managed by
or under the direction of the Board of Directors. The number of directors of the

be designated as Class I, Class II and Class III. The number of directorships
shall be apportioned among the classes so as to maintain the classes as nearly

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 subsequent annual elections, 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
ending at the time of the third succeeding annual meeting of stockholders, or
thereafter in each case when their respective successors are elected and
qualified.
(c) A director may be removed from office only for cause and only
by vote of at least a majority of the outstanding stock entitled to vote in an
election of directors. Any vacancy on the Board of Directors, however resulting,
may be filled only by a majority of the directors then in office, even if less
than a quorum, or by a sole remaining director. Any director elected to fill a
vacancy shall hold office for a term that shall coincide with the term of the
class to which such director shall have been elected.

(a) The Corporation shall indemnify to the fullest extent
authorized or permitted under and in accordance with the laws of the State of
Delaware (as now or hereafter in effect) any person 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, by
reason of the fact that he or she 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, trustee, employee or agent of or in any other capacity
with 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 or her in connection with
such action, 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 his or her conduct was unlawful.
(b) Expenses incurred in defending a civil or criminal action, suit
or proceeding shall (in the case of any action, suit or proceeding against a
director of the Corporation) or may (in the case of any action, suit or
proceeding against an officer, trustee, employee or agent) be paid by the
Corporation in advance of the final disposition of such action, suit or
proceeding as authorized by the Board of Directors upon receipt of an
undertaking by or on behalf of the indemnified person to repay such amount if it
shall ultimately be determined that he or she is not entitled to be indemnified
by the Corporation as authorized in this Article.
(c) This indemnification and other rights set forth in this Article
shall not be exclusive of any provisions with respect thereto in the Bylaws or
any other contract or agreement between the Corporation and any officer,
director, employee or agent of the Corporation.
(d) Neither the amendment nor repeal of paragraph (a), (b) or (c)
of this Article VII, nor the adoption of any provision of this Amended and
Restated Certificate of Incorporation inconsistent with paragraph (a), (b) or
(c) of this Article VII, shall eliminate or reduce the effect of paragraphs (a),
(b) and (c) of this Article VII, in respect of any matter occurring before such
amendment, repeal or adoption of an inconsistent provision or in respect of any
cause of action, suit or claim relating to any such matter which would have
given rise to a right of indemnification or right to receive expenses pursuant
to paragraph (a), (b) or (c) of this Article VII, if such provision had not been
so amended or repealed or if a provision inconsistent therewith had not been so
adopted.
(e) No director shall be liable to the Corporation or its
stockholders for monetary damages for breach of fiduciary duty as a director,
except liability:
(i) for any breach of the director's duty of loyalty to the
Corporation or its stockholders;

intentional misconduct or a knowing violation of law;
(iii) under Section 174 of the General Corporation Law of the State
of Delaware; or
(iv) for any transaction from which a director derived an improper
personal benefit.
If the General Corporation Law of the State of Delaware is amended
after the date of this Amended and Restated Certificate of Incorporation to
authorize corporate action further eliminating or limiting the personal
liability of directors, then the liability of a director of the Corporation
shall be eliminated or limited to the fullest extent permitted by the General
Corporation Law of the State of Delaware, as so amended.
