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.&#148;

The Restated Certificate of Incorporation also provides that no amendment or repeal of such

court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Act

Item 6.
Indemnification of Directors and Officers.
Section 145(a) of the Delaware General Corporation Law (the "DGCL") provides in relevant part
that "[a] corporation shall have power to indemnify 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 (other than an action by or in the right
of the corporation) by reason of the fact that the 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 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 the person in connection with such action, suit or
proceeding if the person acted in good faith and in a manner the person 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 the person's conduct was unlawful." With
respect to derivative actions, Section 145(b) of the DGCL provides in relevant part that "[a]
corporation shall have power to 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 person's service in one of the
capacities specified in the preceding sentence] against expenses (including attorneys' fees)
actually and reasonably incurred by the person in connection with the defense or settlement of such
action or suit if the person acted in good faith and in a manner the person reasonably believed to
be in or not opposed to the best interests 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."
The Registrant's Amended and Restated Certificate of Incorporation provides that to the
fullest extent permitted by the DGCL, no director of the Registrant shall be personally liable to
the Registrant or its stockholders for monetary damages for breach of fiduciary duty as a director.
The Restated Certificate of Incorporation also provides that no amendment or repeal of such
provision shall apply to or have any effect on the right to indemnification permitted thereunder
with respect to claims arising from acts or omissions occurring in whole or in part before the
effective date of such amendment or repeal whether asserted before or after such amendment or
repeal.
The Registrant's bylaws provide for the indemnification of officers, directors and third
parties acting on behalf of the Registrant if such person acted in good faith and in a manner
reasonably believed to be in and not opposed to the best interest of the Registrant,
Table of Contents
and, with respect to any criminal action or proceeding, the indemnified party had no reason to
believe his or her conduct was unlawful. The Registrant has entered into indemnification agreements
with its directors and certain of its executive officers and intends to enter into indemnification
agreements with new directors and certain of its executive officers in the future.
The Registrant carries officer and director liability insurance with respect to certain
matters, including matters arising under the Securities Act.

Item 9.
Undertakings.
A) The undersigned registrant hereby undertakes:
1)
To file, during any period in which offers or sales are being made, a post-effective
amendment to this registration statement:
(i)
To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933;
(ii)
To reflect in the prospectus any facts or events arising after the effective date of
the registration statement (or the most recent post-effective amendment thereof) which,
individually or in the aggregate, represent a fundamental change in the information set forth in
the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of
securities offered (if the total dollar value of securities offered would not exceed that which was
registered) and any deviation from the low or high end of the estimated maximum offering range may
be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) (§
230.424(b) of this chapter) if, in the aggregate, the changes in volume and price represent no more
than a 20% change in the maximum aggregate offering price set forth in the "Calculation of
Registration Fee" table in the effective registration statement.
(iii)
To include any material information with respect to the plan of distribution not
previously disclosed in the registration statement or any material change to such information in
the registration statement;
Provided, however,
that paragraphs (1)(i) and (1)(ii) do not apply if the information required
to be included in a post-effective amendment by those paragraphs is contained in periodic reports
filed with or furnished to the Commission by the registrant pursuant to Section 13 or 15(d) of the
Exchange Act that are incorporated by reference herein.
2)
That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
3)
To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.
B) The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act, each filing of
the registrant's annual report pursuant to Section 13(a) or Section
15(d) of the Exchange Act (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to Section 15(d) of
the Securities Exchange Act of 1934) that is incorporated by
reference in the registration statement shall be deemed to be a new
registration statement relating to the securities offered therein,
and the offering of such securities at that time shall be deemed to
be the initial bona fide offering thereof.
C) Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling
persons of the registrant pursuant to the foregoing provisions, or
otherwise, the registrant has been advised that in the opinion of the
Securities and Exchange Commission such indemnification is against public
policy as expressed in the Act and is, therefore, unenforceable. In the
event that a claim for indemnification against such liabilities (other
than the payment by the registrant of expenses incurred or paid by a
director, officer or controlling person of the registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities
being registered, the registrant will, unless in the opinion of its
counsel the matter has been settled by controlling precedent, submit to a
court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Act
and will be governed by the final adjudication of such issue.
