Item 5. Interests of Named Experts and Counsel.

Not required to be filed with this Registration Statement pursuant to General Instruction E to Form S-8.

Item 6. Indemnification of Directors and Officers.

The Delaware General Corporation Law (the “DGCL”) and the Registrant’s Amended and Restated Certificate of Incorporation, as amended (the “Charter”), and the Registrant’s Amended and Restated By-Laws, as amended (the “By-Laws”), provide for indemnification of the Registrant’s directors and officers for liabilities and expenses that they may incur in such capacities. In general, directors and officers are indemnified with respect to actions taken in good faith in a manner reasonably believed to be in, or not opposed to, the best interests of the Registrant, and with respect to any criminal action or proceeding, actions that the director or officer had no reasonable cause to believe were unlawful.

The Charter provides that the Registrant will, to the full extent permitted under Section 145 of the DGCL, advance payment of expenses and maintain insurance against liability on behalf of all persons for whom it may take each such respective action pursuant to the DGCL. Section 145 of the DGCL provides 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, suit or proceeding, whether civil, criminal, administrative or investigative, by reason of the fact that he or she is or was a director, officer, employee or agent of the corporation or is or was serving at its request in such capacity in another corporation or business association against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by him or her 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.

The By-Laws also provide that the Registration shall indemnify, and advance expenses, to the fullest extent permitted by applicable law, to each person who is or was a director, officer, employee, agent or fiduciary of the Registrant or of any other corporation, partnership, joint venture, trust, employee benefit plan or other enterprise which such person is or was serving at the request of the Registrant in the event such person is, or is threatened to be made, a party to any action, suit, arbitration, alternate dispute resolution mechanism, investigation, administrative hearing or any other threatened, pending or completed proceeding whether civil, criminal, administrative or investigative (a “Proceeding”) due to such person’s status as a director, officer, employee, agent or fiduciary of the Registrant or of any other corporation, partnership, joint venture, trust, employee benefit plan or other enterprise which such person is or was serving at the request of the Registrant, if such person acted in good faith. Further, such indemnification shall continue as to an indemnitee who has ceased to be a director or officer, and shall inure to the benefit of the estate, heirs, executors and administrators of the indemnitee. However, such indemnification shall not extend to (A) such Proceeding as to which the indemnitee shall have been adjudged to be liable to the corporation if applicable law prohibits such indemnification or (B) such Proceeding brought by the indemnitee or made by the indemnitee against the Registrant.

The By-Laws provide that rights of indemnification and to receive advancement of expenses are not exclusive of any other rights to which indemnitee may at any time be entitled under applicable law, the Charter, the By-Laws, any agreement, a vote of stockholders or a resolution of directors, or otherwise. The Registrant has obtained director and officer liability insurance for the benefit of its directors and officers.

The By-Laws specifically authorize the Registrant to enter into agreements with officers, directors, employees or agents of the Registrant providing indemnification rights, to the extent authorized from time to time by its Board of Directors.
