<P align="left" style="margin-left:3%; font-size: 10pt">(i)&nbsp;To include any prospectus required by Section&nbsp;10(a)(3) of the Securities Act;

end of the estimated maximum offering range may be reflected in the form of prospectus filed
with the SEC pursuant to rule 424(b) if, in the aggregate, the changes in volume and price
represent no more than 20&nbsp;percent change in the maximum aggregate offering price set forth
in the &#147;Calculation of Registration Fee&#148; table in the effective registration statement; and



<P align="left" style="margin-left:3%; font-size: 10pt">(iii)&nbsp;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;


<P align="left" style="font-size: 10pt"><I>Provided</I>, <I>however</I>, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if the registration
statement is on Form&nbsp;S-3, Form&nbsp;S-8 or Form&nbsp;F-3, and 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 SEC by the registrant pursuant to Section&nbsp;13 or 15(d) of the Securities Exchange
Act of 1934 that are incorporated by reference in the registration statement.



<P align="left" style="font-size: 10pt">(2)&nbsp;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 <I>bona fide </I>offering thereof.



<P align="left" style="font-size: 10pt">(3)&nbsp;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.



<P align="left" style="font-size: 10pt">(b)&nbsp;That, for the purpose of determining any liability under the Securities Act, each filing of the
registrant&#146;s annual report pursuant to Section&nbsp;13(a) or 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 herein, and the offering of such
securities at the time shall be deemed to be the initial <I>bona fide </I>offering hereof.



<P align="left" style="font-size: 10pt">(c)&nbsp;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 SEC 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.

ITEM 9. UNDERTAKINGS
The undersigned registrant hereby undertakes:
(a)(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 value 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 SEC pursuant to rule 424(b) if, in the aggregate, the changes in volume and price
represent no more than 20 percent change in the maximum aggregate offering price set forth
in the "Calculation of Registration Fee" table in the effective 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;
Provided
,
however
, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if the registration
statement is on Form S-3, Form S-8 or Form F-3, and 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 SEC by the registrant pursuant to Section 13 or 15(d) of the Securities Exchange
Act of 1934 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.
(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) That, for the purpose 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 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 herein, and the offering of such
securities at the time shall be deemed to be the initial
bona fide
offering hereof.
(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 SEC 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.
