ITEM 17.  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
of 1933;

(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% 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 the undertakings set forth in paragraphs (i),
(ii) and (iii) above 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 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, or is contained in a form of
prospectus filed pursuant to Rule 424(b) that is part of this registration
statement.

(2) That, for the purpose of determining any liability under the Securities Act
of 1933, 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.

(4) That, for the purpose of determining liability under the Securities Act of
1933 to any purchaser, each prospectus filed pursuant to Rule 424(b) as part of
a registration statement relating to an offering, other than registration
statements relying on Rule 430B or other than prospectuses filed in reliance on
Rule 430A, shall be deemed to be part of and included in the registration
statement as of the date it is first used after effectiveness. Provided,
however, that no statement made in a registration statement or prospectus that
is part of the registration statement or made in a document incorporated or
deemed incorporated by reference into the registration statement or prospectus
that is part of the registration statement will, as to a purchaser with a time
of contract of sale prior to such first use, supersede or modify any statement
that was made in the registration statement or prospectus that was part of the
registration statement or made in any such document immediately prior to such
date of first use.

 (5) That, for the purpose of determining liability of the Registrant under the
Securities Act of 1933 to any purchaser in the initial distribution of the
securities:

The undersigned Registrant undertakes that in a primary offering of securities
of the undersigned Registrant pursuant to this registration statement,
regardless of the underwriting method used to sell the securities to the
purchaser, if the securities are offered or sold to such purchaser by means of
any of the following communications, the undersigned Registrant will be a seller
to the purchaser and will be considered to offer or sell such securities to such
purchaser:

(i) Any preliminary prospectus or prospectus of the undersigned Registrant
relating to the offering required to be filed pursuant to Rule 424;

(ii) Any free writing prospectus relating to the offering prepared by or on
behalf of the undersigned Registrant or used or referred to by the undersigned
Registrant;

(iii) The portion of any other free writing prospectus relating to the offering
containing material information about the undersigned Registrant or its
securities provided by or on behalf of the undersigned Registrant; and

(iv) Any other communication that is an offer in the offering made by the
undersigned Registrant to the purchaser.

(b) The undersigned Registrant hereby undertakes that, for purposes of
determining any 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 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
of 1933 ("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 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, officers 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 Act and will be governed by the final adjudication of
such issue.

Pursuant to the requirements of the Securities Act of 1933, Registrant certifies
