Item 6.
Indemnification of Directors and Officers
.
Section 102 of the Delaware General Corporation Law allows a corporation to limit directors' personal liability to the corporation or its stockholders from monetary damages for breach of fiduciary duty as a director, with certain exceptions. Paragraph Tenth of the Registrant's Certificate of Incorporation provides that a director of the Registrant shall not be personally liable to the Registrant or its stockholders for monetary damages for breach of fiduciary duty as a director, except for liability (i) for any breach of the director's duty of loyalty to the Registrant or its stockholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) for unlawful payment of dividends or for unlawful stock purchase or redemption of the corporation's stock under Section 174 of the Delaware General Corporation Law, (iv) for any transaction from which the director derived an improper personal benefit or (v) for any act or omission occurring prior to the date Paragraph Tenth became effective.
- 1 -
Section 145 of the Delaware General Corporation Law permits a corporation, subject to the standards set forth therein, to indemnify any person in connection with any action, suit or proceeding brought or threatened by reason of the fact that such person is or was a director, officer, employee or agent of the corporation or is or was serving as such with respect to another entity at the request of the corporation.
Article Seventh of the Registrant's Certificate of Incorporation provides for full indemnification of its directors and officers to the extent permitted by Section 145 of the Delaware General Corporation Law. In addition, Article V of the Registrant's Amended and Restated By-Laws provides for indemnification of persons by reason of the fact that he or she is or was serving as a director and/or officer of the Registrant.
In addition to the provisions in its Certificate of Incorporation and its Amended and Restated By-Laws, the Registrant has taken such other steps as are reasonably necessary to effect its indemnification policy. Included among such other steps is liability insurance provided by the Registrant for its directors and officers for certain losses arising from claims or charges made against them in their capacities as directors or officers of the Registrant. The Registrant has also entered into indemnification agreements with individual directors. These agreements generally provide such directors with a contractual right of indemnification to the fullest extent provided by applicable law as in effect at the respective dates of such agreements and as amended from time to time.
Item 7.

Not applicable.
Item 8.
Exhibits
.
See Exhibit Index.
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 this 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 this 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 SEC 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 Registration Fee" table in the effective registration statement;
(iii)     To include any material information with respect to the plan of distribution not previously disclosed in this Registration Statement or any material change to such information in this 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 SEC by the Registrant pursuant to Section 13 or Section 15(d) of the Exchange Act that are incorporated by reference in this Registration Statement.
- 2 -
(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 this 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 SEC 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.
