Item 6. Indemnification of Directors and Officers.
Section 102(b)(7) of the General Corporation Law of the State of Delaware (the "DGCL") permits a corporation, in its certificate of incorporation, to limit or eliminate the liability of
directors to the corporation or its stockholders for monetary damages for breaches of fiduciary duty, except for liability (a) for any breach of the director's duty of loyalty to the corporation or its stockholders, (b) for acts or
omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (c) for the unlawful payment of a dividend or an unlawful stock purchase or redemption under Section 174 of the DGCL, or (d) for any
transaction from which the director derived an improper personal benefit. Article X of the Registrant's Restated Certificate of Incorporation contains provisions intended to limit a director's personal liability to the fullest extent
permitted under the DGCL.
Under Section 145 of the DGCL, a corporation has the power to indemnify directors and officers
under certain circumstances, subject to certain limitations, against specified costs and expenses actually and reasonably incurred in connection with an action, suit or proceeding, whether civil, criminal, administrative or investigative.
Article VI of the Registrant's By-Laws provides that the Registrant will indemnify any person who was or is made or is threatened to be made a party or is otherwise involved in any action, suit or proceeding, whether civil, criminal,
administrative or investigative by reason of the fact that such person, or an individual for whom such person is the legal representative, is or was a director, officer, employee or agent of the Registrant or is or was serving at the request of the
Registrant as a director, officer, employee or agent of another corporation or of a partnership, joint venture, trust, enterprise or non-profit entity, against all liability and loss suffered and expenses reasonably incurred by such person.
Article VI of the Registrant's By-Laws further permits the Registrant to maintain insurance on behalf of any person who is or was or has agreed to become a director or officer of the Registrant, or is or was serving at the request of the
Registrant as a director or officer of another corporation, partnership, joint venture, trust or other enterprise against any liability asserted against such person and incurred by such person or on such person's behalf in any such capacity, or
arising out of such person's status as such, whether or not the Registrant would have the power to indemnify such person against such liability under the provisions of the Registrant's By-Laws.

Item 9. Undertakings.
(a)
The undersigned Registrant hereby undertakes:
(1)
To file, during any period in which offers of 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;
(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) of this
section 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 Exchange Act that are incorporated by reference in this 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 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.
- 4 -
(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.
