Item 4.		Description of Securities.
		Not Applicable.

Item 6.		Indemnification of Directors and Officers.
Delaware law permits a corporation to include a provision in its certificate of incorporation eliminating or limiting the personal liability of each of its directors, but not an officer in his or her capacity as such, to the corporation and its stockholders for monetary damages for breach of fiduciary duty as a director, except that such provision cannot eliminate or limit the liability of a director for (1) any breach of the director's duty of loyalty to the corporation or its stockholders, (2) acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (3) liability under section 174 of the Delaware General Corporation Law for unlawful payment of dividends or stock purchases or redemptions, or (4) any transaction from which the director derived an improper personal benefit. The Registrant's certificate of incorporation provides that the personal liability of the directors of the Registrant to
4
the Registrant and its stockholders for monetary damages shall be eliminated or limited to the fullest extent permissible under applicable law as may be amended from time to time.
Under Delaware law, a corporation is permitted to 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 (other than an action by or in the right of the corporation), by reason of the fact that the person is or was an officer, director, employee or agent of the corporation or is or was serving at the request of the corporation as an officer, director, employee or agent of another corporation, partnership, joint venture, trust or other enterprise against expenses (including attorney's fees), judgments, fines and amounts paid in settlement actually and reasonably incurred in connection with such proceeding: (1) if the person acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the corporation; and (2) in the case of a criminal proceeding, the person had no reasonable cause to believe that his conduct was unlawful.
A corporation also is permitted to 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 obtain a judgment in its favor by reason of the fact that the person is or was an officer, director, 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 attorney's fees) actually and reasonably incurred in connection with the defense or settlement of such action or suit if the person acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the corporation, provided that no such indemnification is permitted with respect to any claim, issue or matter as to which the person is found liable to the corporation unless and only to the extent that the Delaware Court of Chancery or the court in which the action or suit is brought determines the person is fairly and reasonably entitled to indemnification for such expenses as the court shall deem proper.
Under Delaware law, a corporation is required to indemnify any current or former director or officer of the corporation who is successful on the merits or otherwise in the defense of any action, suit or proceeding against such person by reason of the fact that the person is or was an officer, director, 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 actually and reasonably incurred. Expenses incurred by an officer or director in defending civil, criminal, administrative or investigative proceedings may be paid by the corporation in advance of the final disposition of such proceedings upon receipt of an undertaking by or on behalf of such director or officer to repay such amount if it shall ultimately be determined that the person is not entitled to be indemnified by the corporation. Expenses incurred by former officers and directors or other employees or agents in defending such proceedings may be paid upon terms deemed appropriate by the corporation.
The Registrant's certificate of incorporation provides that the Registrant shall indemnify and advance expenses to any director, officer or employee of the Registrant, and may indemnify or advance expenses to any other person, who is, was or is threatened to be made a party to an action, suit or proceeding, whether civil, criminal, administrative or investigative, by
5
reason of his or her service as a director, officer, employee or agent of the Registrant or his or her service as a director, officer, employee or agent of another entity at the request of the Registrant, to the fullest extent permitted by applicable law; provided that in the case of an advancement of expenses, if required by the Delaware General Corporation Law, an undertaking is first delivered to the Registrant, by or on behalf of such director, officer, employee or agent, to repay all amounts so advanced if it is ultimately determined that the director, officer, employee or agent is not entitled to be indemnified under the certificate of incorporation.

Item 9.			Undertakings.
			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:
			(a)     to include any prospectus required by Section 10(a)(3) of the Securities Act of 1933;
			(b)     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
6
			dollar value of the 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 Securities and Exchange Commission (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
			(c)     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 1(a) and 1(b) do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed with or furnished to the Commission by the Registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in this Registration Statement.
(2)  That, for the purpose of determining any liability under the Securities Act of 1933, each 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.
The undersigned Registrant hereby undertakes that, for purposes of determining liability under the Securities Act of 1933, each filing of the Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan's annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in this Registration Statement shall be deemed to be a new registration statement relating to the securities offered herein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
Insofar as indemnification for liabilities arising under the Securities Act of 1933 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 Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act of 1933 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 1933 and will be governed by the final adjudication of such issue.
