                  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 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 upon 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 or currency unit 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
Alvarez, Esq., Puerto Rico counsel to the Corporation, PNA and PIB, 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



Popular, Inc.,                                                              -16-

                  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 trustees thereunder, assumptions that we have not independently
verified. Finally, we have assumed that the authority granted in the Corporation
Resolutions, PNA Resolutions and PIB Resolutions will remain in effect at all
relevant times.

                  This opinion may be relied upon by Brunilda Santos de Alvarez,
Esq. as to matters of the laws of the State of New York and the General
Corporation Law of the State of Delaware.

                  We hereby consent to the filing of this opinion as an exhibit
to the Registration Statement and to the
