  <DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Section&nbsp;102 of the Delaware General Corporation Law permits a corporation to eliminate the
  personal liability of its directors or its stockholders for monetary damages for a breach of
  fiduciary duty as a director, except where the director breached his or her duty of loyalty, failed
  to act in good faith, engaged in intentional misconduct or knowingly violated a law, authorized the
  payment of a dividend or approved a stock repurchase in violation of Delaware corporate law or
  obtained an improper personal benefit. The registrant&#146;s restated certificate of incorporation
  provides that no director shall be personally liable to the registrant or its stockholders for
  monetary damages for any breach of fiduciary duty as director, notwithstanding any provision of law
  imposing such liability, except to the extent that the Delaware General Corporation Law prohibits
  the elimination or limitation of liability of directors for breaches of fiduciary duty.

  <DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Section&nbsp;145 of the Delaware General Corporation Law provides that a corporation has the power

  serving at the request of the corporation in related capacities against expenses (including
  attorneys&#146; fees), judgments, fines and amounts paid in settlements actually and reasonably incurred
  by the person in connection with an action, suit or proceeding to which he or she is or is
  threatened to be made a party by reason of such position, if such person 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, in any criminal action or proceeding, had no reasonable cause to believe his or
  her conduct was unlawful, except that, in the case of actions brought by or in the right of the
  corporation, no indemnification shall be made with respect to 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 other adjudicating court determines that, despite the
  adjudication of liability but in view of all of 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.

  reason of the fact that he or she is or was, or has agreed to become, a director or officer, or is

  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

  stock.
  Item 6. Indemnification of Directors and Officers.
  Section 102 of the Delaware General Corporation Law permits a corporation to eliminate the
  personal liability of its directors or its stockholders for monetary damages for a breach of
  fiduciary duty as a director, except where the director breached his or her duty of loyalty, failed
  to act in good faith, engaged in intentional misconduct or knowingly violated a law, authorized the
  payment of a dividend or approved a stock repurchase in violation of Delaware corporate law or
  obtained an improper personal benefit. The registrant's restated certificate of incorporation
  provides that no director shall be personally liable to the registrant or its stockholders for
  monetary damages for any breach of fiduciary duty as director, notwithstanding any provision of law
  imposing such liability, except to the extent that the Delaware General Corporation Law prohibits
  the elimination or limitation of liability of directors for breaches of fiduciary duty.
  Section 145 of the Delaware General Corporation Law provides that a corporation has the power
  to indemnify a director, officer, employee or agent of the corporation and certain other persons
  serving at the request of the corporation in related capacities against expenses (including
  attorneys' fees), judgments, fines and amounts paid in settlements actually and reasonably incurred
  by the person in connection with an action, suit or proceeding to which he or she is or is
  threatened to be made a party by reason of such position, if such person 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, in any criminal action or proceeding, had no reasonable cause to believe his or
  her conduct was unlawful, except that, in the case of actions brought by or in the right of the
  corporation, no indemnification shall be made with respect to 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 other adjudicating court determines that, despite the
  adjudication of liability but in view of all of 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 restated certificate of incorporation provides that it will indemnify each
  person who was or is a party or threatened to be made a party to any threatened, pending or
  completed action, suit or proceeding, other than an action by or in the right of the registrant, by
  reason of the fact that he or she is or was, or has agreed to become, a director or officer, or is
  or was serving, or has agreed to serve at the registrant's request, as a director, officer,
  partner, employee or trustee of, or in a similar capacity with, another corporation, partnership,
  joint venture, trust or other enterprise, all such persons being referred to as an indemnitee, or
  by reason of any action alleged to have been taken or omitted in such capacity, against all
  expenses, including attorneys' fees, liabilities, losses, judgments, fines, excise taxes and
  penalties arising under the Employee Retirement Income Security Act of 1974, and amounts paid in
  settlement actually and reasonably incurred by or on behalf of an indemnitee in connection with
  such action, suit or proceeding and any appeal therefrom, if such indemnitee acted in good faith
  and in a manner which he or she reasonably believed to be in, or not opposed to, the registrant's
  best interests, and, with respect to any criminal action or proceeding, had no reasonable cause to
  believe his or her conduct was unlawful.
  Table of Contents
  The registrant's restated certificate of incorporation provides that it will indemnify any
  indemnitee who was or is a party to or threatened to be made a party to any threatened, pending or
  completed action or suit by or in the right of the registrant to procure a judgment in the
  registrant's favor by reason of the fact that the indemnitee is or was, or has agreed to become,
  the registrant's director or officer, or is or was serving, or has agreed to serve, at the
  registrant's request, as a director, officer, partner, employee or trustee of, or in a similar
  capacity with, another corporation, partnership, joint venture, trust or other enterprise, or by
  reason of any action alleged to have been taken or omitted in such capacity, against all expenses,
  including attorneys' fees, and, to the extent permitted by law, amounts paid in settlement actually
  and reasonably incurred by or on behalf of the indemnitee in connection with such action, suit or
  proceeding and any appeal therefrom, if the indemnitee acted in good faith and in a manner which
  the indemnitee reasonably believed to be in, or not opposed to, the registrant's best interests,
  except that no indemnification shall be made in respect of any claim, issue or matter as to which
  the indemnitee shall have been adjudged to be liable to the registrant, unless, and only to the
  extent that, the Court of Chancery of Delaware or the court in which such action or suit was
  brought determines upon application that, despite the adjudication of such liability but in view of
  all the circumstances of the case, the indemnitee is fairly and reasonably entitled to indemnity
  for such expenses, including attorneys' fees, which the Court of Chancery of Delaware or such other
  court shall deem proper. Expenses must be advanced to an indemnitee under certain circumstances.
  The registrant has entered into indemnification agreements with each of its directors and its
  executive officers. These indemnification agreements require the registrant, among other things, to
  indemnify its directors and executive officers for some expenses, including attorneys' fees,
  judgments, fines and settlement amounts, incurred by a director or executive officer in any action
  or proceeding arising out of his or her service as one of the registrant's directors or executive
  officers, or any of its subsidiaries or any other company or enterprise to which the person
  provides services at the registrant's request.
  The registrant maintains a general liability insurance policy that covers certain liabilities
  of directors and officers of the registrant arising out of claims based on acts or omissions in
  their capacities as directors or officers.
  Item 7. Exemption from Registration Claimed.
  Not applicable.
  Item 8. Exhibits.
  The Exhibit Index immediately preceding the exhibits is incorporated herein by reference.
  Item 9. Undertakings.
  1.
  Item
  512(a)
  of Regulation S-K
  . 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;
  (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,
  Table of Contents
  individually or in the aggregate, represent a fundamental change in the information set
  forth in the registration statement; and
  (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 (i) and (ii) do not apply if the information required to
  be included in a post-effective amendment by those paragraphs is contained in reports filed
  with or furnished to the Commission by the registrant pursuant to Section 13 or Section
  15(d) of the Exchange Act that are incorporated by reference in the registration statement.
  (2) That, for the purpose of determining any liability under the Securities Act, 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.
  2.
  Item
  512(b)
  of Regulation S-K
  . 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 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.
  3.
  Item
  512(h)
  of Regulation S-K
  . Insofar as indemnification for liabilities arising
  under the Securities Act 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 Securities 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 Securities Act and will be governed by the final adjudication of such
  issue.
