he, his testator or intestate is or was a director, officer or employee of

indemnification by individual contracts with the directors and officers, and
(ii)&nbsp;that Registrant shall not be required to indemnify any director or officer
unless the indemnification is required by law, the proceeding in which
indemnification is sought was authorized in advance by our board of directors,
the indemnification is provided by Registrant, in its sole discretion pursuant
to the powers vested in Registrant under the General Corporation Law or the

its directors and executive officers providing indemnification of such
directors and executive officers by Registrant to the fullest extent
permitted by law, subject to certain limited exceptions.

All documents subsequently filed by Registrant pursuant to Sections 13(a),

Item 6. Indemnification of Directors and Officers.
Section 145
("Section 145")
of the General Corporation Law of the State of
Delaware, as the same exists or may hereafter be amended (the
"General
Corporation Law"
) provides that a Delaware corporation may 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
such corporation) by reason of the fact that such person is or was a director,
officer, employee or agent of such corporation, or is or was serving at the
request of such corporation as a director, officer, employee or agent of
another corporation or enterprise. The indemnity may include
Table of Contents
expenses (including attorneys' fees), judgments, fines and amounts paid in
settlement actually and reasonably incurred by such person in connection with
such action, suit or proceeding, provided such person acted in good faith and
in a manner such person reasonably believed to be in or not opposed to the
best interests of the corporation and, with respect to any criminal action or proceeding, had no
reasonable cause to believe that such person's conduct was
unlawful.
Section 145 further authorizes a corporation to purchase and maintain
insurance on behalf of any person who is or was a director, officer, 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 or
enterprise, against any liability asserted against such person and incurred by
such person in any such capacity, arising out of such person's status as such,
whether or not the corporation would otherwise have the power to indemnify such
person against such liability under Section 145.
Registrant's Amended and Restated Certificate of Incorporation provides
that Registrant may indemnify to the fullest extent permitted by law any person
made or threatened to be made a party to an action or proceeding, whether
criminal, civil, administrative or investigative, by reason of the fact that
he, his testator or intestate is or was a director, officer or employee of
Registrant or any predecessor of Registrant or serves or served at any
other enterprise as a director, officer or employee at the request of
Registrant or any predecessor to Registrant.
Registrant's Bylaws provide for the mandatory indemnification of the
directors and officers to the maximum extent permitted by the General Corporation
Law. The Bylaws also provide (i) that Registrant may modify the scope of
indemnification by individual contracts with the directors and officers, and
(ii) that Registrant shall not be required to indemnify any director or officer
unless the indemnification is required by law, the proceeding in which
indemnification is sought was authorized in advance by our board of directors,
the indemnification is provided by Registrant, in its sole discretion pursuant
to the powers vested in Registrant under the General Corporation Law or the
indemnification is required by individual contract. In addition, the Bylaws
provide that Registrant has the power to indemnify its employees and agents to
the maximum extent permitted by the General Corporation Law.
Registrant's directors and executive officers are covered by insurance
maintained by Registrant against specified liabilities for actions taken in
their capacities as such, including liabilities under the Securities Act of
1933, as amended (the
"Securities Act"
). In addition, Registrant has entered into contracts with
its directors and executive officers providing indemnification of such
directors and executive officers by Registrant to the fullest extent
permitted by law, subject to certain limited exceptions.

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; 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.
(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 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 Registrant pursuant to the foregoing provisions, or otherwise, Registrant
has been advised that in the opinion of the Commission such indemnification is
against public policy as expressed in the Act and is, therefore, unenforceable.
In the event that a claim for indemnification against such liabilities (other
than the payment by Registrant of expenses incurred or paid by a director,
officer or controlling person of Registrant in the successful defense of any
action, suit or proceeding) is
-3-
Table of Contents
asserted by such director, officer or controlling person in connection
with the securities being registered, 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.
