         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,


Popular, Inc.                                                               -11-

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 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
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.
