UNDERTAKINGS The Company 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) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement; (iii) To include any material information about the plan of distribution not already disclosed in the registration statement or any material change to such information in the registration statement; provided, however, that paragraphs (1)(i) and (1)(ii) do not apply if the registration statement is on Form S-3 or Form S-8 and the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed 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. (2) that, for purposes of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be a new registration statement relating to the securities offered, and the offering of such securities at that time will be viewed as the initial bona fide offering. (3) to remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the end of the offering. (4) 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 will be a new registration statement relating to the securities offered, and the offering of such securities at that time shall be viewed as the initial bona fide offering. Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant under 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 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 Act and will be governed by the final adjudication of such issue. SIGNATURES Under the requirements of the Securities Act of 1933, the Registrant has reasonable grounds to believe that it meets all of the requirements for filing on Form S-8 and has caused this Registration Statement to be signed on its behalf by the authorized signer in The City of New York, State of New York, on the 18th day of December, 2003.

In giving such consent, I do not admit that I come within the category of persons whose consent is required under Section 7 of the Securities Act of 1933, or the Rules and Regulations of the Securities and Exchange Commission.
