  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&#146; fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by the person in connection with such

  cause to believe the person&#146;s conduct was unlawful. The termination of any action, suit or proceeding by judgment, order, settlement, conviction, or upon a plea of nolo contendere or its equivalent, shall not, of itself, create a presumption
  that the person did not act in good faith and in a manner which 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 reasonable cause to believe

  the capacities set forth above, against expenses (including attorneys&#146; fees) actually and reasonably incurred by the person in connection with the defense or settlement of such action or suit if the person acted under similar standards to those

  for breaching his or her duty of loyalty, engaging in intentional misconduct or knowingly violating the law, paying a dividend or approving a stock repurchase which was illegal, or obtaining an improper personal benefit. A provision of this type has

  <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">The indemnity agreements also require the Registrant to make prompt payment of expenses incurred by the director or executive officer in

  Item 5.
  Interests of Named Experts and Counsel.
  The validity of the issuance of Common Stock registered hereby is passed on for the Registrant by Cynthia L. Tregillis. Ms. Tregillis is
  the Senior Vice President, Chief Legal Officer and Secretary of the Company and is compensated by the Company as an employee. As of the date hereof, Ms. Tregillis owns 10,918 shares of Common Stock, 90,475 restricted stock units that are
  payable in an equivalent number of shares of Common Stock, 3,539 performance stock units (at the target level of performance, or, if applicable, as credited) that are payable in an equivalent number of shares of Common Stock, and no Company stock
  options to acquire shares of Common Stock.
  Item 6.
  Indemnification of Directors and Officers.
  The Registrant is a Delaware corporation. Section 145(a) of the Delaware General Corporation Law (the "DGCL") provides that a
  Delaware corporation may 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. The termination of any action, suit or proceeding by judgment, order, settlement, conviction, or upon a plea of nolo contendere or its equivalent, shall not, of itself, create a presumption
  that the person did not act in good faith and in a manner which 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 reasonable cause to believe
  that the person's conduct was unlawful.
  Section 145(b) of the DGCL provides that a Delaware corporation may 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 fact that the person acted in any of
  the capacities set forth above, 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 under similar standards to those
  set forth above, except that no indemnification may be made in 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 in which such action
  or suit was brought shall determine that despite the adjudication of liability, in view of all the circumstances of the case, such person is fairly and reasonably entitled to be indemnified for such expenses which the court shall deem proper.
  2
  Section 145 of the DGCL further provides, among other things, that to the extent a
  present or former director or officer of the corporation has been successful in the defense of any action, suit or proceeding referred to in subsection (a) and (b) of Section 145 or in the defense of any claim, issue or matter therein,
  such person shall be indemnified against expenses (including attorneys' fees) actually and reasonably incurred by him or her in connection therewith; that indemnification provided for by Section 145 shall not be deemed exclusive of any
  other rights to which the indemnified party may be entitled, and that the corporation may purchase and maintain insurance on behalf of a director or officer of the corporation against any liability asserted against such officer or director and
  incurred by him or her in any such capacity or arising out of his or her status as such, whether or not the corporation would have the power to indemnify him or her against such liabilities under Section 145.
  As permitted by Section 102(b)(7) of the DGCL, the Registrant's certificate of incorporation provides that a director or officer
  shall not be liable to the Registrant or its stockholders for monetary damages for breach of fiduciary duty as a director. However, such provision does not eliminate or limit the liability of such person for acts or omissions not in good faith or
  for breaching his or her duty of loyalty, engaging in intentional misconduct or knowingly violating the law, paying a dividend or approving a stock repurchase which was illegal, or obtaining an improper personal benefit. A provision of this type has
  no effect on the availability of equitable remedies, such as injunction or rescission, for breach of fiduciary duty.
  The
  Registrant's bylaws require that directors and officers be indemnified to the maximum extent permitted by Delaware law. In addition to the indemnification provisions in the Registrant's bylaws, the Registrant has entered into indemnity
  agreements with each director and executive officer of the Registrant. These indemnity agreements require that the Registrant indemnify each director and executive officer to the fullest extent permitted by the DGCL.
  The indemnity agreements also require the Registrant to make prompt payment of expenses incurred by the director or executive officer in
  connection with any proceeding upon the request of the director or executive officer in advance of indemnification to the extent permitted by law.
  The Registrant has a policy of directors' liability insurance which insures the directors and officers against the cost of defense,
  settlement or payment of a judgment under certain circumstances stated in the policy.
  The above discussion of the DGCL and of the
  Registrant's certificate of incorporation, bylaws, and indemnification agreements is not intended to be exhaustive and is qualified in its entirety by such statute, certificate of incorporation, bylaws and indemnification agreements.

  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;
  (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) if, in the aggregate, the changes in volume and price represent no more than 20% change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the
  effective 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;
  p
  rovided, however,
  that
  paragraphs (a)(1)(i) and (a)(1)(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 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, 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; and
  (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
  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.
  (c) 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 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.
