We note that, as of the date of this opinion, a judgment for money in an action based on a Debt Security denominated in a foreign currency or currency unit, or on a related Guarantee, in a Federal or state court in the United 12 Popular, Inc. Popular International Bank, Inc. Popular North America, Inc. -12- States ordinarily would be enforced in the United States only in United States dollars. The date used to determine the rate of conversion of the foreign currency or currency unit in which a particular Debt Security is denominated into United States dollars will depend on various factors, including which court renders the judgment. In the case of a Debt Security denominated in a foreign currency, or a related Guarantee, a state court in the State of New York rendering a judgment on a Debt Security, or on a related Guarantee, would be required under Section 27 of the New York Judiciary Law to render such judgment in the foreign currency in which the Debt Security is denominated, and such judgment would be converted into United States dollars at the exchange rate prevailing on the date of entry of the judgment. The foregoing opinion is limited to the Federal laws of the United States, the laws of the State of New York and the Commonwealth of Puerto Rico, and the General Corporation Law of the State of Delaware, and we are expressing no opinion as to the effect of the laws of any other jurisdiction. With respect to all matters of the laws of the Commonwealth of Puerto Rico, we have relied upon the opinion, dated the date hereof, of Brunilda Santos de 13 Popular, Inc. Popular International Bank, Inc. Popular North America, Inc. -13- Alvarez, Counsel to the Corporation, and our opinion is subject to the same assumptions, qualifications and limitations with respect to such matters as are contained in such opinion of Brunilda Santos de Alvarez. Also, we have relied as to certain matters on information obtained from public officials, officers of the Corporation, PNA and PIB, and other sources believed by us to be responsible, and we have assumed that each of the Popular Senior Indenture, the Popular Subordinated Indenture and the PNA Senior Indenture has been duly authorized, executed and delivered by the respective Trustee thereunder, assumptions that we have not independently verified. We hereby consent to the filing of this opinion as an exhibit to the Registration Statement and to the references to us under the heading "Validity of Offered Securities" in the Prospectus contained in the Registration Statement. 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/ Sullivan & Cromwell
