Item 4. Description of Securities.

Not applicable.

Item 5. Interests of Named Experts and Counsel.

Not Applicable.

Item 6. Indemnification of Directors and Officers.

The certificate of incorporation and bylaws of the Registrant provide that the Registrant will indemnify and advance expenses, as permitted by the Delaware General Corporation Law, to each person who is or was a director or officer of the Registrant, or who serves or served as a director, officer, employee or agent of any other enterprise or organization at the request of the Registrant (an “Indemnitee”).

Under Delaware law, to the extent that an Indemnitee is successful on the merits in defense of a suit or proceeding brought against him or her by reason of the fact that he or she is or was a director, officer, or agent of the Registrant, or serves or served any other enterprise or organization at the request of the Registrant, the Registrant shall indemnify him or her against expenses (including attorneys’ fees) actually and reasonably incurred in connection with such action.

If unsuccessful in defense of a third-party civil suit or a criminal suit, or if such a suit is settled, an Indemnitee may be indemnified under Delaware law against both (i) expenses, including attorney’s fees, and (ii) judgments, fines and amounts paid in settlement 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 Registrant, and, with respect to any criminal action, had no reasonable cause to believe his or her conduct was unlawful.

If unsuccessful in defense of a suit brought by or in the right of the Registrant, or where the suit is settled, an Indemnitee may be indemnified under Delaware law only against expenses (including attorneys’ fees) actually and reasonably incurred in the defense or settlement of the 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 Registrant, except that if the Indemnitee is adjudged to be liable for negligence or misconduct in the performance of his or her duty to the Registrant, he or she cannot be made whole even for expenses unless a court determines that he or she is fully and reasonably entitled to indemnification for such expenses.

Also under Delaware law, expenses incurred by an officer or director in defending a civil or criminal action, suit, or proceeding may be paid by the Registrant in advance of the final disposition of the suit, action or proceeding upon receipt of an undertaking by or on behalf of the officer or director to repay such amount if it is ultimately determined that he or she is not entitled to be indemnified by the Registrant. The Registrant may also advance expenses incurred by other employees and agents of the Registrant upon such terms and conditions, if any, that the Board of Directors of the Registrant deems appropriate.

In addition, the Registrant has entered into indemnification agreements that require the Registrant to indemnify the directors, officers, and certain other representatives of the Registrant against expenses and certain other liabilities arising out of their conduct on behalf of the Registrant to the maximum extent and under all circumstances permitted by law.

The Registrant maintains insurance policies that indemnify its directors and officers against various liabilities arising under the Securities Act and the Exchange Act that might be incurred by any director or officer in his capacity as such.
