         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 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

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,

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, Financial and PIB, and

other sources believed by us to be responsible.
