  <DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Company&#146;s charter provides that the Company will indemnify all persons whom it shall have
  power to indemnify to the full extent permitted by state law. Under Delaware law, a director,
  officer, employee or agent who has been successful on the merits or otherwise in defense of any
  action, suit or proceeding or in defense of any claim, issue or matter therein shall be indemnified
  against expenses (including attorney&#146;s fees) actually and reasonably incurred. In other
  circumstances, a director, officer, employee or agent of the Company may be indemnified against
  expenses (including attorney&#146;s fees), judgments, fines and amounts paid in settlement actually and
  reasonably incurred if he/she acted in good faith and in a manner reasonably believed to be in or
  not opposed to the best interest of the Company, except that in an action or suit by or in the
  right of the Company, such person shall not be indemnified if he/she has been adjudged to be liable
  to the Company unless otherwise determined by the Court of Chancery. The Company&#146;s charter further
  provides that directors are not liable for monetary damages for certain violations of their duty of
  care. A determination that indemnification of a director, officer, employee or agent is proper
  shall be made by a disinterested majority of directors, by independent legal counsel or by the
  stockholders of the Company.

  provisions or otherwise, the Company 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 of 1933 and is, therefore, unenforceable. In the event that a claim for indemnification
  against such liabilities (other than the payment by the Company of expenses incurred or paid by a
  director, officer or controlling person of the Company 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 Company 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 of 1933 and will be governed by the final adjudication of such issue.

  Item 6.      INDEMNIFICATION OF DIRECTORS AND OFFICERS.
  The Company's charter provides that the Company will indemnify all persons whom it shall have
  power to indemnify to the full extent permitted by state law. Under Delaware law, a director,
  officer, employee or agent who has been successful on the merits or otherwise in defense of any
  action, suit or proceeding or in defense of any claim, issue or matter therein shall be indemnified
  against expenses (including attorney's fees) actually and reasonably incurred. In other
  circumstances, a director, officer, employee or agent of the Company may be indemnified against
  expenses (including attorney's fees), judgments, fines and amounts paid in settlement actually and
  reasonably incurred if he/she acted in good faith and in a manner reasonably believed to be in or
  not opposed to the best interest of the Company, except that in an action or suit by or in the
  right of the Company, such person shall not be indemnified if he/she has been adjudged to be liable
  to the Company unless otherwise determined by the Court of Chancery. The Company's charter further
  provides that directors are not liable for monetary damages for certain violations of their duty of
  care. A determination that indemnification of a director, officer, employee or agent is proper
  shall be made by a disinterested majority of directors, by independent legal counsel or by the
  stockholders of the Company.

  Item 9.      UNDERTAKINGS.
  A.    The Company 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 which, individually or in the
  aggregate, represent a fundamental change in the information set forth in the
  registration statement;
  (iii) To include any material information with respect to the plan of
  4
  Table of Contents
  distribution not previously disclosed in the registration statement, or any material
  change to such information in the registration statement;
  provided
  ,
  however
  , that paragraphs (A)(1)(i) and (A)(1)(ii) do not apply if the
  information required to be in a post-effective amendment by those paragraphs is
  contained in periodic reports filed by the Company pursuant to Section 13 or Section
  15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in
  the registration statement.
  (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 Plan.
  B.    The Company hereby undertakes that, for purposes of determining any liability under the
  Securities Act of 1933, each filing of the Company's annual report pursuant to Section 13(a) or
  Section 15(d) of the Securities Exchange Act of 1934 (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 under the Securities Act of 1933 may be
  permitted to directors, officers, and controlling persons of the Company pursuant to the foregoing
  provisions or otherwise, the Company 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 of 1933 and is, therefore, unenforceable. In the event that a claim for indemnification
  against such liabilities (other than the payment by the Company of expenses incurred or paid by a
  director, officer or controlling person of the Company 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 Company 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 of 1933 and will be governed by the final adjudication of such issue.
