Item 4. Description of Securities.

Not Applicable.

Item 5. Interests of Named Experts and Counsel.

The validity of the securities being registered hereby has been passed upon for the Registrant by Pamela Taylor, Vice President and Assistant Secretary of the Registrant. Ms. Taylor is a full-time employee of the Registrant, owns less than 0.1% of the outstanding shares of Common Stock and is eligible to (i) receive awards under the Stock and Incentive Plan and (ii) participate in the ESPP.

Item 6. Indemnification of Directors and Officers.

The discussion below summarizes the material indemnification provisions of the Registrant's amended and restated certificate of incorporation ("certificate of incorporation") and by-laws and Section 145 of the General Corporation Law of the State of Delaware (the "DGCL").

Section 145 of the DGCL provides that a Delaware corporation has the power, under specified circumstances, to indemnify its directors, officers, employees and agents or persons who are or were serving at the request of the corporation as directors, officers, employees or agents of another entity. Indemnification is allowed in connection with threatened, pending, or completed actions, suits, or proceedings, whether civil, criminal, administrative or investigative, other than an action by or in right of the corporation, brought against them by reason of the fact that they were or are directors, officers, employees or agents, for expenses, judgments, fines and amounts paid in settlement actually and reasonably incurred in connection with such action, suit, or proceeding if: (1) 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 (2) with respect to any criminal proceeding, he or she had no reasonable cause to believe that his or her 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 a person did not act in good faith and in a manner which he or she reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal proceeding, had reasonable cause to believe that his or her conduct was unlawful.

Section 35 of the Registrant's by-laws provides for mandatory indemnification, to the fullest extent permitted by the DGCL as it existed at the time the indemnification provisions of the Registrant's by-laws were adopted or as it is thereafter amended, of each person who was or is or is threatened to be made a witness in or a party to any action, suit, arbitration, alternative dispute resolution mechanism, investigation, administrative hearing or any other proceeding, whether civil, criminal, administrative or investigative, because:

•the person is or was an officer or director of the Registrant;

•the person is an employee or agent of the Registrant (and not also a director or officer of the Registrant) and the board of directors of the Registrant adopts a resolution specifically stating that such person shall be entitled to some or all of the benefits of Section 35 of the Registrant's by-laws (an "Other Indemnified Person"); or

•is a director, officer or Other Indemnified Person who is or was serving at the request of the Registrant as a director, officer or administrator of any other corporation, partnership, joint venture, trust, employee benefit plan or other enterprise.

Section 35 of the Registrant's by-laws expressly provides that the right to indemnification as set forth therein is not exclusive of any other right that any person may have or acquire.

Section 145 of the DGCL provides that a Delaware corporation has the power to purchase and maintain insurance on behalf of its directors, officers, employees or agents against liabilities asserted against and incurred by such person in his or her capacity or arising out of his or her status as a director, officer, employee or agent of the corporation. A Delaware corporation has this power whether or not the corporation has the power to indemnify such person against such liability under Section 145 of the DGCL.

Section 35 of the Registrant's by-laws provides that the Registrant may maintain insurance, at its own expense, to protect itself and any person, including any person who is or was a director, officer, employee or agent of the Registrant or of another entity, against any expense, liability or loss. This insurance coverage may be maintained regardless of whether the Registrant would have the power to indemnify such person against such expense, liability or loss under the DGCL.

Section 102(b)(7) of the DGCL provides that a certificate of incorporation may contain a provision eliminating or limiting the personal liability of a director or officer to the corporation or its stockholders for monetary damages for breach of fiduciary duty as a director or officer. However, that provision shall not eliminate or limit the liability of:

•a director or officer for any breach of the director's or officer's duty of loyalty to the corporation or its stockholders;

•a director or officer for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law;

•a director under Section 174 of the DGCL, relating to liability for unlawful acquisitions or redemptions of, or payment of dividends on, capital stock;

•a director or officer for any transaction from which the director or officer derived an improper personal benefit; or

•an officer in any action by or in the right of the corporation.

Article XV of the Registrant's certificate of incorporation provides that, to the fullest extent permitted by the DGCL, no director or officer shall be personally liable to the corporation or its stockholders for monetary damages for breach of fiduciary duty as a director or officer, subject to certain exceptions.

The foregoing statements are subject to the detailed provisions of Sections 145 and 102 of the DGCL and the Registrant's certificate of incorporation and by-laws.

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;

(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 Filing Fee Tables" or "Calculation of Registration Fee" table, as applicable, 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; provided, 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 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; 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 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.
