The above opinions are subject to the effects of applicable bankruptcy, insolvency and similar laws affecting creditors’ rights generally, concepts of reasonableness and equitable principles of general applicability, and subject to possible judicial or regulatory actions giving effect to governmental actions or foreign laws affecting creditors’ rights.

In connection with the opinions expressed above, we have assumed that at or prior to the time of the delivery of any Securities (i) the Board of Directors of the Company shall have duly established the terms of such Securities and duly authorized the issuance and sale of such Securities and such authorization shall not have been modified or rescinded, (ii) the Company is and shall remain validly existing as a sociedad anónima organized under the laws of the Kingdom of Spain, (iii) the relevant Trustee is and shall remain validly existing as a corporation in good standing under the laws of its jurisdiction of incorporation, (iv) the Registration Statement shall have become effective and such effectiveness shall not have been terminated or rescinded, (v) the Securities (other than as expressly covered above in respect of the Company) and the Indentures are each valid, binding and enforceable agreements of each party thereto; and (vi) there shall not have occurred any change in law affecting the validity or enforceability of the Indentures or any such Securities.

We express no opinion as to (i) whether a New York State or U.S. federal court would render or enforce a judgment in a currency other than U.S. Dollars or enforce the exclusivity of the jurisdiction of the Spanish courts in the city of Madrid or waivers of holders and owners of Securities provided for in the Indentures and the Securities for the purposes described therein, or (ii) the exchange rate that such a court would use in rendering a judgment in U.S. Dollars in respect of an obligation in any other currency.

We note that the choice-of-law provisions of the Indentures and the Securities, as applicable, are expressed to select Spanish law as the governing law for certain matters related to the Indentures and the Securities, including the authorization and execution of the Indentures, the authorization, issuance and execution of the Securities and certain provisions of the Indentures and the Securities related to the status and ranking or subordination, as applicable, of the Securities, the waiver of rights of set-off and the Spanish Bail-in Power (as such term is defined therein). We also note that the submission-to-jurisdiction provisions of the Indentures and the Securities, as applicable, are expressed to provide that the Spanish courts in the city of Madrid shall have exclusive jurisdiction in respect of any suit or proceeding arising out of or relating to the Securities or the Indentures arising out of, relating to or in connection with the exercise of the Spanish Bail-in Power by the Relevant Spanish Resolution Authority (as such terms are defined therein).

We are members of the Bar of the State of New York and the foregoing opinion is limited to the laws of the State of New York and the federal laws of the United States, except that we express no opinion as to (i) any law, rule or regulation that is applicable to the Company or the Indentures or the Securities or the transactions contemplated thereby solely because such law, rule or regulation is part of a regulatory regime applicable to any party to any of the Indentures or the Securities or any of its affiliates due to the specific assets or business of such party or such affiliate, (ii) the impact of any executive order or (iii) any law, rule or regulation relating to national security. Insofar as the foregoing opinion involves matters governed by the laws of the Kingdom of Spain, we have relied, without independent inquiry or investigation, on the opinion of J&A Garrigues, S.L.P., Spanish legal counsel for the Company, to be filed on the date hereof as an exhibit to the Registration Statement, and our opinion is subject to the qualifications, assumptions and limitations set forth therein.

We hereby consent to the filing of this opinion as an exhibit to the Registration Statement referred to above and further consent to the reference to our name under the caption “Validity of the Securities” in the Prospectus. In giving this consent, we do not admit that we are in the category of persons whose consent is required under Section 7 of the Securities Act.
