If the legal proceeding, however, is by or in the right of the Company, the director or officer (i)&#160;may be indemnified by the Company only for expenses (including attorneys&#8217; fees) but not for judgments, fines or amounts paid in settlements and (ii)&#160;may not be indemnified for expenses in respect of any claim, issue or matter as to which he or she shall have been adjudged to be liable to the Company unless a court determines otherwise.</p>

The Company&#8217;s Restated Certificate of Incorporation also contains a provision that eliminates, subject to certain exceptions, to the fullest extent permitted by the Delaware General Corporation Law, the personal liability of each director of the Company to the Company and its stockholders for monetary damages for breaches of fiduciary duty as a director. The Registrant&#8217;s Fourth Amended and Restated Bylaws also provide that the Registrant may advance the payment of expenses, upon receipt of an undertaking by or on behalf of such person to repay such amounts if it should be determined ultimately that such person is not entitled to be indemnified under the bylaws or otherwise, and that the indemnification and advancement of expense provisions of the bylaws are nonexclusive. The Registrant maintains director and officer liability insurance covering director and officer indemnification.</p>

Pursuant to such agreements, the Company will, to the extent permitted by applicable law, indemnify such persons against all expenses, judgments, fines and penalties incurred in connection with the defense or settlement of any actions brought against them by reason of the fact that they were directors or officers of the Company or assumed certain responsibilities at the direction of the Company. These indemnification agreements provide for the creation of a trust account in the event of a &#8220;change in control&#8221; (as defined in the indemnification agreements), funded in an amount sufficient to reasonably satisfy any and all expenses incurred by a director or executive officer in connection with investigating, preparing for, participating in, and/or defending any proceeding relating to any Indemnifiable Event (as defined in the indemnification agreements). The trustee of such trust account is to be selected by the director or executive officer receiving the indemnity under the indemnification agreements. The preceding discussion of the Company&#8217;s indemnification agreements is not intended to be exhaustive and is qualified in its entirety by reference to such indemnification agreements.</p>

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 Company is a Delaware corporation subject to the applicable indemnification provisions of the General Corporation Law of the State of Delaware, which is referred to herein as the "Delaware General Corporation Law." Under Section 145 of the Delaware General Corporation Law, each director and officer of the Company may be indemnified by the Company against all expenses and liabilities (including attorney's fees, judgments, fines and amounts paid in settlement) actually and reasonably incurred in connection with the defense or settlement of any threatened, pending or completed legal proceedings (other than a proceeding by or in the right of the Company) in which he or she is involved by reason of the fact that he or she is or was a director or officer of the Company if such director or officer acted in good faith and in a manner that he or she reasonably believed to be in or not opposed to the best interests of the Company and, with respect to any criminal action or proceeding, if he or she had no reasonable cause to believe that his or her conduct was unlawful. If the legal proceeding, however, is by or in the right of the Company, the director or officer (i) may be indemnified by the Company only for expenses (including attorneys' fees) but not for judgments, fines or amounts paid in settlements and (ii) may not be indemnified for expenses in respect of any claim, issue or matter as to which he or she shall have been adjudged to be liable to the Company unless a court determines otherwise.
The Company's Fourth Amended and Restated Bylaws and Restated Certificate of Incorporation both provide for the indemnification of the Company's directors and officers, to the fullest extent permitted by the Delaware General Corporation Law, for all liability and loss (including attorney's fees) incurred in defending actions brought against them arising out of the performance of their duties. The Company's Restated Certificate of Incorporation also contains a provision that eliminates, subject to certain exceptions, to the fullest extent permitted by the Delaware General Corporation Law, the personal liability of each director of the Company to the Company and its stockholders for monetary damages for breaches of fiduciary duty as a director. The Registrant's Fourth Amended and Restated Bylaws also provide that the Registrant may advance the payment of expenses, upon receipt of an undertaking by or on behalf of such person to repay such amounts if it should be determined ultimately that such person is not entitled to be indemnified under the bylaws or otherwise, and that the indemnification and advancement of expense provisions of the bylaws are nonexclusive. The Registrant maintains director and officer liability insurance covering director and officer indemnification.
The foregoing is only a general summary of certain aspects of Delaware law and the Company's Restated Certificate of Incorporation and Fourth Amended and Restated Bylaws dealing with indemnification of directors and officers and does not purport to be complete. It is qualified in its entirety by reference to the detailed provisions of the Delaware General Corporation Law and the Company's Restated Certificate of Incorporation and Fourth Amended and Restated Bylaws.
The Company has entered into indemnification agreements with its directors and executive officers, and intends to enter into indemnification agreements with any new directors and executive officers in the future. Pursuant to such agreements, the Company will, to the extent permitted by applicable law, indemnify such persons against all expenses, judgments, fines and penalties incurred in connection with the defense or settlement of any actions brought against them by reason of the fact that they were directors or officers of the Company or assumed certain responsibilities at the direction of the Company. These indemnification agreements provide for the creation of a trust account in the event of a "change in control" (as defined in the indemnification agreements), funded in an amount sufficient to reasonably satisfy any and all expenses incurred by a director or executive officer in connection with investigating, preparing for, participating in, and/or defending any proceeding relating to any Indemnifiable Event (as defined in the indemnification agreements). The trustee of such trust account is to be selected by the director or executive officer receiving the indemnity under the indemnification agreements. The preceding discussion of the Company's indemnification agreements is not intended to be exhaustive and is qualified in its entirety by reference to such indemnification agreements.

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 a 20 percent 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;
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 periodic reports filed 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.
(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.
