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

increase in the number of the Registrant's outstanding Shares.

The Proposed Maximum Offering Price Per Share has been estimated in accordance with Rule 457(c) under the Securities Act solely for the purpose of calculating the registration fee on the basis of the average of the

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.
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 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
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 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 of the Registrant under the Securities Act
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, each filing of the 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 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
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 of 1933 and will be governed by the final adjudication of such issue.
