         transfer, reorganization, moratorium and similar laws of general
         applicability relating to or affecting creditors' rights and to general
         equity principles.

                  (x) When the Registration Statement has become effective under
         the Act, a certificate of designations with respect to the PNA
         Preferred Stock has been duly filed and recorded with the Secretary of
         State of the State of Delaware, the terms of the PNA Preferred Stock

         relating to or affecting creditors' rights and to general equity
         principles.

                  I 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



Popular, Inc.                                                                -9-

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 General Corporation Law of the State of Delaware and the laws
of the State of New York and the Commonwealth of Puerto Rico, and I am
expressing no opinion as to the effect of the laws of any other jurisdiction.
With respect to all matters of the laws of the State of New York and of the
State of Delaware, I have relied upon the opinion, dated the date hereof, of
Sullivan & Cromwell LLP, and my opinion is subject to the same assumptions,
qualifications and limitations with respect to such matters as are contained in
such opinion of Sullivan & Cromwell LLP.

                  Also, I have relied as to certain matters on information
obtained from public officials, officers of the Corporation, PNA and PIB, and
other sources believed by me to be responsible, and I 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 which I have not independently
verified. Finally, I 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 Sullivan & Cromwell LLP as
to matters of the laws of the Commonwealth of Puerto Rico.

                  I hereby consent to the filing of this opinion as an exhibit
to the Registration Statement and to the reference to me under the heading
"Validity of Offered Securities" in the Prospectus contained in the Registration
Statement. In giving such consent, I do not thereby admit that I am in the
category of persons whose consent is required under Section 7 of the Act.

                                                  Very truly yours,
