advised that in the opinion of the Securities and Exchange Commission such
indemnification is against public policy as expressed in the Securities Act and
is, therefore, unenforceable.&#160; In 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.</font></p>

Item 6.  Indemnification of Directors and Officers.
Delaware General
Corporation Law
Section 145 of the Delaware General Corporation Law (the "DGCL")
provides that a corporation may indemnify any person who was or is a party or
is threatened to be made a party to any threatened, pending or
2
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 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, partnership, joint venture, trust or other enterprise,
against expenses (including attorneys' fees), judgments, fines and amounts paid
in settlement actually and reasonably incurred by the person in connection with
such action, suit or proceeding if the person acted in good faith and in a
manner the 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 the person's conduct was
unlawful. Section 145 of the DGCL further provides that a corporation
similarly 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 or suit by or in
the right of the corporation to procure a judgment in its favor by reason of
the fact that the person 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, partnership, joint
venture, trust or other enterprise against expenses (including attorneys' fees)
actually and reasonably incurred by the person in connection with the defense
or settlement of such action or suit if the person acted in good faith and in a
manner that the person reasonably believed to be in or not opposed to the best
interests of the corporation and except that no indemnification shall be made
in respect of any claim, issue or matter as to which such person shall have
been adjudged to be liable to the corporation unless and only to the extent
that the Delaware Court of Chancery or such other court in which such action or
suit was brought shall determine upon application that, despite the
adjudication of liability but in view of all of the circumstances of the case,
such person is fairly and reasonably entitled to indemnity for such expenses
which the Delaware Court of Chancery or such other court shall deem proper.
Section 145 of the DGCL also provides that a corporation has the
power 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, partnership, joint venture, trust or other enterprise
against any liability asserted against such person and incurred by such person
in any such capacity, or arising out of such person's status as such, whether
or not the corporation would have the power to indemnify such person against
such liability under this section.
Certificate of
Incorporation and By-Laws
The Registrant's amended and restated certificate of incorporation and
its by-laws provide for the indemnification of officers and directors to the
fullest extent permitted by the DGCL.
Insurance
The Registrant's directors and officers are covered under directors'
and officers' liability insurance policies maintained by the Registrant against
certain liabilities taken in their capacities as such, including liabilities
under the Securities Act.

Filed herewith
Item 9.  Undertakings
(a)           The
undersigned registrant hereby undertakes:
(1)           To file, during any period in which
offers or sales are being made of securities registered hereby, 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.
(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 with or furnished to the
Commission by the registrant pursuant to Section 13 or 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; and
(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 further 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 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.
5
(h)           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 Securities and Exchange 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.
