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

UNDERTAKINGS
1.
The undersigned registrant hereby undertakes:
(a)
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, as
amended (the "Securities Act");
Table of Contents
(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)(i) and (a)(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 issuer pursuant to section 13 or section 15(d) of
the Securities Exchange Act of 1934, as amended (the "Exchange Act") that are incorporated by
reference herein.
(b)
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 herein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.
(c)
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.
2.
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 herein, and the offering of such
securities at that time shall be deemed to be the initial bona fide offering thereof.
3.
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.
