Item 4. Description of Securities.

Not applicable.

Item 5. Interests of Named Experts and Counsel.

Not applicable.

Item 6. Indemnification of Directors and Officers.

Section 145(a) of the General Corporation Law of the State of Delaware, as amended ("DGCL") provides, in general, that a corporation may indemnify any person who was or is a party to 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), because he or she 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 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, with respect to any criminal action or proceeding, had no reasonable cause to believe his or her conduct was unlawful. Section 145(b) of the DGCL provides, in general, that a 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 because 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) actually and reasonably incurred by the person in connection with the defense or settlement of such action or suit if 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, except that no indemnification shall be made with respect to any claim, issue or matter as to which he or she 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, he or she is fairly and reasonably entitled to indemnity for such expenses that the Court of Chancery or other adjudicating court shall deem proper.

Section 145(g) of the DGCL provides, in general, that a corporation may purchase and maintain insurance on behalf of any person who 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 any liability asserted against such person and incurred by such person 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 the person against such liability under Section 145 of the DGCL. As permitted by the DGCL, the Registrant's amended and restated certificate of incorporation limits the liability of its directors to the fullest extent permitted by the DGCL providing that a director will not be personally liable for monetary damages to the Registrant or its stockholders for breach of fiduciary duty as a director to the extent so permitted. The amended and restated certificate of incorporation also provides that each current or former director, officer, employee or agent of the Registrant, or each such person who is or was serving or who had agreed to serve at the request of the Registrant as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or any other enterprise will be indemnified by the Registrant to the full extent permitted by law, as the same exists or may in the future be amended. The Registrant's bylaws provide that it will indemnify, and provide expense advancement to, its directors and officers to the fullest extent permitted by such law, subject to certain exceptions contained in the Registrant's amended and restated bylaws.

Pursuant to Section 102(b)(7) of the DGCL, the Registrant's Amended and Restated Certificate of Incorporation eliminates the liability of a director to the Registrant or its stockholders for monetary damages for breach of fiduciary duty as a director to the fullest extent permitted by the DGCL, as may be amended from time to time. The Registrant has approved and entered into indemnification agreements with each of its directors and executive officers. These agreements provide that the Registrant will indemnify, and provide expense advancement and reimbursement to, each of its directors and such officers to the fullest extent permitted by law and its amended and restated certificate of incorporation and its bylaws, subject to certain exceptions contained in those agreements. Any claims for indemnification by the Registrant's directors and officers may reduce the Registrant's available funds to satisfy successful third-party claims against it and may reduce the amount of money available to the Registrant. The Registrant also maintains a general liability insurance policy, which will cover 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.
