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.</font></p>

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;
(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 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)(i) and (a)(ii) of this section 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 the
registration statement.
(b)
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 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.
(d)
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.
2.
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 (and, where
applicable, each filing of an employee benefit plan's annual report pursuant to
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 herein, and the
offering of such securities at that time shall be deemed to be the initial
bona fide
offering thereof.
3
3.
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
Securities and Exchange 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.
