Ladies and Gentlemen:

         We have acted as special tax counsel to ABN AMRO Bank N.V., a limited liability company incorporated under the laws of the Netherlands (the “Company”), in connection with the preparation and filing of a Pricing Supplement (No. 20) dated September 3, 2003 (the “Pricing Supplement”) to a supplemental prospectus dated July 8, 2002 (the “Supplemental Prospectus”) to registration statement number 333-89136 on Form F-3 (the “Registration Statement”). This opinion is being furnished in accordance with the requirements of Item 601(b)(8) of Regulation S-K of the Securities Act of 1933, as amended (the “Act”).

We have reviewed the discussion contained under the heading “United States Federal Income Taxation” in the Pricing Supplement. In our opinion, such discussion, insofar as it related to U.S. federal income tax matters, and subject to the conditions and limitations set forth in the discussion, sets forth the material U.S. federal income tax considerations applicable generally to U.S. holders of the securities offered pursuant to the Pricing Supplement (the “Securities”) as a result of the ownership and disposition of the Securities.

We hereby consent to the filing of this opinion as an exhibit to the Registration Statement and to the references to us under the headings “United States Federal Income Taxation” in the Pricing Supplement included therein. In giving such consent, we do not thereby admit that we are in the category of persons whose consent is required under Section 7 of the Act.

Very truly yours,

/s/ Davis Polk & Wardwell
