FORM OF OPINION OF GENERAL COUNSEL OF TELEFÓNICA

April 28, 2017

Citigroup Global Markets Inc.

388 Greenwich Street

New York, NY 10013

Re:     Telefónica, S.A. 2017 SEC-Registered Debt Offering

Ladies and Gentlemen,

I am Ramiro Sánchez de Lerín García-Ovies, General Counsel of Telefónica, S.A., a stock corporation (sociedad anónima) organized under the laws of the Kingdom of Spain (the “Guarantor”), and in that capacity I am familiar with the legal affairs of the Guarantor and its subsidiaries. This opinion is delivered to you in connection with the issuance by Telefónica Emisiones, S.A.U. (the “Company”), a stock corporation with a single shareholder (sociedad anónima unipersonal) organized under the laws of the Kingdom of Spain and a wholly owned subsidiary of the Guarantor, of $500,000,000 aggregate principal amount of its 5.213% Fixed Rate Senior Notes due 2047 (the “Notes”). The Notes will be unconditionally guaranteed pursuant to the guarantee (the “Guarantee”) as to payment of principal, interest and premiums, if any, by the Guarantor. Pursuant to the Underwriting Agreement dated April 24, 2017 (the “Underwriting Agreement”) between you, the Guarantor and the Company, you have agreed to purchase or procure purchasers for the Notes to be issued pursuant to the indenture between the Company, the Guarantor and The Bank of New York Mellon, as Trustee, dated May 22, 2012 (the “Base Indenture”), as supplemented by a supplemental fixed rate note indenture dated as of March 8, 2017, pursuant to which the 5.213% Fixed Rate Senior Notes will be issued (the Base Indenture and the supplemental indenture, collectively the “Indentures”). This opinion is delivered to you pursuant to Section 2(b) of the Underwriting Agreement. All capitalized terms not otherwise defined herein shall have the meanings ascribed to them in the Underwriting Agreement.

In rendering the opinions expressed herein, I, or members of my staff upon whom I am relying, have examined originals or copies, certified or otherwise identified to my or their satisfaction, of such documents, corporate records and other instruments as I or they have deemed necessary or appropriate, including the following:

(i) the Underwriting Agreement;

(ii) the registration statement registered with the U.S. Securities and Exchange Commission (the “SEC”) dated May 13, 2015 with file number 333-204118 and the documents incorporated by reference therein (the “Registration Statement”);

(iii) the Prospectus dated May 13, 2015 relating to the offering of debt securities of the Company included in the Registration Statement and the documents incorporated by reference therein (the “Prospectus”);

Exhibit A to the Underwriting Agreement – 1

(iv) the Preliminary Prospectus Supplement dated April 24, 2017 and filed with the SEC on April 24, 2017 relating to the offering of the Notes and the documents incorporated by reference therein (the “Preliminary Prospectus Supplement”);

(v) final term sheet dated April 24, 2017 (the “Final Term Sheet” and, together with the Prospectus, the Preliminary Prospectus Supplement and the Prospectus Supplement, the “Disclosure Package”);

(vi) the final Prospectus Supplement dated April 24, 2017 and filed with the SEC on April 25, 2017 relating to the offering of the Notes and the documents incorporated by reference therein (the “Prospectus Supplement”);

(vii) the Guarantee;

(viii) the Indentures;

(ix) the global note dated April 28, 2017 relating to the Notes (the “Global Note”);

(x) a copy of the public deed of issuance of the Notes (escritura de emisión) executed on April 25, 2017, before the Notary Public of Madrid Mr. José Miguel García Lombardía (the “Public Deed of Issuance”);

(xi) a copy of the bylaws (estatutos) of the Guarantor;

(xii) a copy of the bylaws (estatutos) of the Company;

(xiii) a copy of a certificate of the secretary of the Board of Directors of the Guarantor, Mr. Ramiro Sánchez de Lerín García-Ovies, with respect to the resolutions approved by the General Shareholders’ Meeting of the Guarantor on May 30, 2014;

(xiv) a copy of a certificate of the secretary of the Board of Directors of the Guarantor, Mr. Ramiro Sánchez de Lerín García-Ovies, with respect to the minutes of the meeting of the Board of Directors of the Guarantor held on May 30, 2014 in relation to the issue of the Notes and the Guarantee;

(xv) a copy of a certificate of the secretary of the Board of Directors of the Guarantor, Mr. Ramiro Sánchez de Lerín García-Ovies, with respect to the resolutions approved by the Executive Commission of the Guarantor at its meetings held on April 29, 2015 and February 10, 2017; and

(xvi) a copy of a certificate of the Joint and Several Director of the Company, Mr. Eduardo José Álvarez Gómez, with respect to the resolutions adopted by the Guarantor as sole shareholder of the Company on May 4, 2015 in relation to the issue of the Notes.

The Underwriting Agreement, the Guarantee and the Indentures are hereinafter collectively referred to as the “Documents”.

The opinions set forth in this letter are based upon the following assumptions:

(i) the genuineness of all signatures, stamps and seals (other than those signatures, stamps and seals of the Guarantor or the Company), the conformity to the originals of all documents supplied to us as certified photostatic or faxed copies and the authenticity of the originals of such documents;

(ii) that the Disclosure Package has been filed with the SEC, and the Documents and the Global Note have been duly executed and delivered on behalf of each of the parties thereto (other than the Guarantor and the Company), in the respective forms examined by us;

Exhibit A to the Underwriting Agreement – 2

(iii) the due authorization, execution and delivery of the Documents and the Global Note by each of the parties thereto (other than the Guarantor and the Company) and that the performance thereof is within the capacity and powers of each of the parties thereto (other than the Guarantor and the Company);

(iv) the absence of any other arrangements between any of the parties to the Underwriting Agreement which modify or supersede any of the terms of the Underwriting Agreement; and

(v) that the terms and conditions of the Notes, the Guarantee, the Indentures and the Underwriting Agreement, constitute legal, valid and binding obligations under the law of the State of New York by which they are expressed to be governed.

Based on the foregoing, and such examination of law as I have deemed necessary, I am of the opinion that:

(i) Each of the Company and the Guarantor has been duly incorporated and is validly existing as a limited liability corporation (sociedad anónima) under the laws of the Kingdom of Spain with corporate power and all requisite authority under such laws to own, lease and operate its respective properties and conduct its respective businesses as described in the Disclosure Package.

(ii) The Underwriting Agreement has been duly authorized, executed and delivered by the Guarantor and the Company.

(iii) The Guarantor owns directly or indirectly all of the outstanding ordinary shares of the Company.

(iv) No filing or registration of the Disclosure Package or any other prospectus or circular is necessary under Spanish law in connection with the issuance, sale or delivery of the Notes and the Guarantee.

(v) Insofar as matters of Spanish law are concerned, the Disclosure Package has been duly authorized by and on behalf of the Company and the Guarantor.

(vi) The statements made in the Guarantor’s Annual Report on Form 20-F for the year ended December 31, 2016, which is incorporated by reference in the Registration Statement, the Preliminary Prospectus Supplement and the Prospectus Supplement, under the captions “Information on the Company – B. Business Overview”, “Directors, Senior Management and Employees – B. Compensation”, “Directors, Senior Management and Employees – C. Board Practices”, “Financial Information – Legal Proceedings”, “The Offering and Listing – C. Markets”, “Additional Information – B. Memorandum and Articles of Association”, “Additional Information – C. Material Contracts”, “Additional Information – D. Exchange Controls” and “Additional Information – E. Taxation” and the statements made in the Preliminary Prospectus Supplement and the Prospectus Supplement under the caption “Taxation—Spanish Tax Considerations”, to the extent that they relate to matters of Spanish law or taxation, in each case as supplemented by the statements made under the caption “Recent Developments” of the Prospectus Supplement, are true and accurate and there are no facts the omission of which from such statements would make the same misleading in any material respect.

Exhibit A to the Underwriting Agreement – 3

(vii) Other than as set forth in the Registration Statement and the Disclosure Package, there are no actions, suits or governmental proceedings pending to which the Company, the Guarantor or any subsidiary of the Guarantor is a party or of which any asset of the Company, the Guarantor, or any subsidiary of the Guarantor is the subject which could reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect, or to impair the ability of the Company or the Guarantor to consummate the transactions contemplated hereby; and, to the best of my knowledge, no such actions, suits or proceedings are threatened or contemplated by any court or governmental, regulatory or stock exchange authority or any other party having jurisdiction over the (i) Company, (ii) the Guarantor or (iii) Telefónica de España, S.A., Telefónica Latinoamerica Holding, S.L. and Telefónica Europe Plc (collectively, the “Material Subsidiaries” and each, a “Material Subsidiary”) or any of their respective assets, which could reasonably be expected to have a Material Adverse Effect.

(viii) None of the Company, the Guarantor or any of the Material Subsidiaries is in violation of its articles of association or other governing documents or, to my knowledge, in default in the performance or observance of any obligation contained in any agreement or instrument to which it is a party or by which it or any of its assets are subject, which violation or default would have a Material Adverse Effect on the business or financial condition of the Guarantor, the Company or any of the Material Subsidiaries or impair the Guarantor’s ability to consummate the transactions contemplated in the Underwriting Agreement.

(ix) Neither the sale of the Notes by the Company, the execution by the Guarantor and the Company, as applicable, of the Documents nor the consummation of any of the other transactions contemplated in the Documents and the Notes will conflict with, result in a breach of, or constitute a default under the bylaws of the Company, the Guarantor or any Material Subsidiary or the terms of any indenture or other agreement or instrument known to such counsel to which the Company, the Guarantor or any Material Subsidiary is a party or is bound, or any order or regulation known to such counsel to be applicable to the Company, the Guarantor or any Material Subsidiary of any court, regulatory body, administrative agency, governmental body or arbitrator having jurisdiction over the Company, the Guarantor or any Material Subsidiary (except for such conflicts, breaches or defaults that would not have a Material Adverse Effect on the financial condition, earnings or business affairs of the Guarantor and its subsidiaries, considered as one enterprise).

(x) The Company, the Guarantor and each of the Material Subsidiaries have all licenses, franchises, permits, authorizations, approvals, and orders from all governmental authorities, that are necessary to own or lease their properties and conduct their respective businesses and that are material to the Guarantor and its subsidiaries, taken as a whole (except for such licenses, franchises, permits, subsidiaries, orders and approvals which the failure to obtain will not have a Material Adverse Effect on the business or financial condition of the Guarantor and its subsidiaries, taken as a whole).

(xi) The statements in the Registration Statement and the Disclosure Package relating to the ranking and the status of the Notes and the Guarantee, to the extent that they relate to matters of Spanish law, are true and accurate and there are no facts the omission of which from such statements would make the same misleading in any material respect.

FORM OF OPINION OF DAVIS POLK & WARDWELL LLP

April 28, 2017

Citigroup Global Markets Inc.

388 Greenwich Street

New York, NY 10013

Ladies and Gentlemen:

We have acted as special United States counsel for Telefónica Emisiones, S.A.U., a sociedad anónima unipersonal organized under the laws of the Kingdom of Spain (the “Company”), and Telefónica, S.A., a sociedad anónima organized under the laws of the Kingdom of Spain, as guarantor (the “Guarantor”), in connection with the Underwriting Agreement dated April —, 2017 (the “Underwriting Agreement”) with you under which you have agreed to purchase from the Company $— aggregate principal amount of the Company’s 5.213% Fixed Rate Senior Notes due 2047 (the “Notes”) guaranteed by the Guarantor (the “Guarantee” and, together with the Notes, the “Securities”). The Securities are to be issued pursuant to the provisions of the Indenture dated as of May 22, 2012 (the “Base Indenture”) among the Company, the Guarantor and The Bank of New York Mellon, as trustee (the “Trustee”), as supplemented by the fifth supplemental fixed rate note indenture dated as of March 8, 2017, pursuant to which the Notes will be issued (the Base Indenture and the fifth supplemental indenture, collectively, the “Indenture”).

We have examined originals or copies of such documents, corporate records, certificates of public officials and other instruments as we have deemed necessary or advisable for the purpose of rendering this opinion.

We have also participated in the preparation of the registration statement of the Company and the Guarantor on Form F-3 (File No. 333-204118) (including the documents incorporated by reference therein (the “Incorporated Documents”)) filed with the Securities and Exchange Commission (the “Commission”) pursuant to the provisions of the Securities Act of 1933, as amended (the “Act”), relating to the registration of securities (the “Shelf Securities”) to be issued from time to time by the Company and the Guarantor, and have participated in the preparation of the preliminary prospectus supplement dated April —, 2017 relating to the Securities, the free writing prospectus dated April —, 2017, identified as Number 1 on Schedule II to the Underwriting Agreement and attached as Exhibit 1 to Schedule III to the Underwriting Agreement, and the prospectus supplement dated April —, 2017, relating to the Securities (the “Prospectus Supplement”). The registration statement became effective under the Act and the Base Indenture qualified under the Trust Indenture Act of 1939, as amended, upon the filing of the registration statement with the Commission on May 13, 2015 pursuant to Rule 462(e). The registration statement at the date of the Underwriting Agreement, including the Incorporated Documents and the information deemed to be part of the registration statement at the time of effectiveness pursuant to Rule 430B under the Act, is hereinafter referred to as the “Registration Statement”, and the related prospectus (including the Incorporated Documents) dated May 13, 2015 relating to the Shelf Securities is

Exhibit B to the Underwriting Agreement – 1

hereinafter referred to as the “Basic Prospectus”. The Basic Prospectus, as supplemented by the Prospectus Supplement, in the form first used to confirm sales of the Securities (or in the form first made available by the Company to you to meet requests of purchasers of the Securities under Rule 173 under the Act), is hereinafter referred to as the “Prospectus”.

In rendering the opinions expressed herein, we have, without independent inquiry or investigation, assumed that (i) all documents submitted to us as originals are authentic and complete, (ii) all documents submitted to us as copies conform to authentic, complete originals, (iii) all documents filed with or submitted to the Commission through its Electronic Data Gathering, Analysis and Retrieval (“EDGAR”) system (except for required EDGAR formatting changes) conform to the versions of such documents reviewed by us prior to such formatting, (iv) all signatures on all documents that we reviewed are genuine, (v) all natural persons executing documents had and have the legal capacity to do so, (vi) all statements in certificates of public officials and officers of the Company and the Guarantor that we reviewed were and are accurate and (vii) all representations made by the Company and the Guarantor as to matters of fact in the documents that we reviewed were and are accurate.

Based upon the foregoing, and subject to the additional assumptions and qualifications set forth below, we are of the opinion that:

(1) Assuming that the Underwriting Agreement has been duly authorized, executed and delivered by the Company and the Guarantor insofar as Spanish law is concerned, the Underwriting Agreement has been duly executed and delivered by the Company and the Guarantor.

(2) Assuming that the Indenture has been duly authorized, executed and delivered by the Company and the Guarantor insofar as Spanish law is concerned, the Indenture has been duly executed and delivered by the Company and the Guarantor, and the Indenture is a valid and binding agreement of the Company and the Guarantor, enforceable in accordance with its terms, subject to applicable bankruptcy, insolvency and similar laws affecting creditors’ rights generally, concepts of reasonableness and equitable principles of general applicability, and may be subject to possible judicial or regulatory actions giving effect to governmental actions or foreign laws affecting creditors’ rights, provided that we express no opinion as to the validity, legally binding effect or enforceability of any provision that permits holders to collect any portion of stated principal amount upon acceleration of the Securities to the extent determined to constitute unearned interest.

(3) Assuming that the Notes have been duly authorized, executed and delivered by the Company insofar as Spanish law is concerned, the Notes, when the Notes are executed and authenticated in accordance with the provisions of the Indenture and delivered to and paid for by you pursuant to the Underwriting Agreement, will be valid and binding obligations of the Company enforceable in accordance with their terms, subject to applicable bankruptcy, insolvency and similar laws affecting creditors’ rights generally, concepts of reasonableness and equitable principles of general applicability, and may be subject to possible judicial or regulatory actions giving effect to governmental actions or foreign laws affecting creditors’ rights, and will be entitled to the benefits of the Indenture pursuant to which such Notes are to be issued, provided that we express no opinion as to the validity, legally binding effect or enforceability of any provision that permits holders to collect any portion of stated principal amount upon acceleration of the Securities to the extent determined to constitute unearned interest.

Exhibit B to the Underwriting Agreement – 2

(4) Assuming the due authorization, execution and delivery of the Notes by the Company insofar as Spanish law is concerned and the due authorization, execution and delivery of the Guarantee endorsed on each Note by the Guarantor insofar as Spanish law is concerned, the Guarantee, when the Notes (and the Guarantee endorsed thereon) are executed and authenticated in accordance with the provisions of the Indenture and delivered to and paid for by you pursuant to the Underwriting Agreement, will be a valid and binding obligation of the Guarantor, enforceable in accordance with its terms, subject to applicable bankruptcy, insolvency and similar laws affecting creditors’ rights generally, concepts of reasonableness and equitable principles of general applicability, and may be subject to possible judicial or regulatory actions giving effect to governmental actions or foreign laws affecting creditors’ rights, provided that we express no opinion as to the validity, legally binding effect or enforceability of any provision that permits holders to collect any portion of stated principal amount upon acceleration of the Securities to the extent determined to constitute unearned interest.

(5) Assuming that each of the Underwriting Agreement and the Base Indenture has been duly authorized, executed and delivered by the Company and the Guarantor insofar as Spanish law is concerned, under the laws of the State of New York relating to personal jurisdiction, each of the Company and the Guarantor has, pursuant to Section 14 of the Standard Provisions attached and incorporated into the Underwriting Agreement (the “Standard Provisions”) and Section 1.15 of the Base Indenture, validly and irrevocably submitted to the extent permitted by law to the exclusive personal jurisdiction of any state or United States federal court located in the Borough of Manhattan, the City of New York, New York (each a “New York Court”) in any action based on or arising under the Notes, the Indenture and the Underwriting Agreement or the transactions contemplated by the Underwriting Agreement, has validly and irrevocably waived to the fullest extent it may effectively do so any objection to the venue of a proceeding in any such New York Court, and has validly and irrevocably appointed CT Corporation System as its authorized agent for the purpose described in Section 14 of the Standard Provisions and Section 1.15 of the Base Indenture; and service of process effected on such agent in the manner set forth in Section 14 of the Standard Provisions and Section 1.15 of the Base Indenture will be effective to confer valid personal jurisdiction on the Company and the Guarantor. We express no opinion as to whether a New York State or United States federal court would enforce the exclusivity of the jurisdiction of any New York State or United States federal court provided for in the Underwriting Agreement or the Indenture.

(6) Neither the Company nor the Guarantor is, and after giving effect to the offering and sale of the Securities and the application of the proceeds thereof as described in the Prospectus will be, required to register as an “investment company” as such term is defined in the Investment Company Act of 1940, as amended.

(7) The execution and delivery by the Company of, and the performance by the Company of its obligations under, the Underwriting Agreement, the Indenture and the Securities (collectively, the “Documents”) and the execution and delivery by the Guarantor, and the performance by the Guarantor of its obligations under, the Documents will not

Exhibit B to the Underwriting Agreement – 3

contravene any provision of the statutory laws of the State of New York or any federal law of the United States of America that in our experience is normally applicable to general business corporations in relation to transactions of the type contemplated thereby, provided that we express no opinion as to federal or state securities laws.

(8) No consent, approval, authorization, or order of, or qualification with, any governmental body or agency under the laws of the State of New York or any federal law of the United States of America that in our experience is normally applicable to general business corporations in relation to transactions of the type contemplated by the Documents is required for the execution, delivery and performance by the Company or the Guarantor of its obligations under the Documents, except such as may be required under federal or state securities or Blue Sky laws as to which we express no opinion.

We have considered the statements included in the Prospectus under the caption “Description of the Notes and the Guarantee” insofar as they summarize provisions of the Notes and the Guarantee. In our opinion, such statements fairly summarize these provisions in all material respects. The statements included in the Prospectus under the caption “Taxation—Material U.S. Federal Income Tax Considerations,” insofar as they purport to describe provisions of U.S. federal income tax laws or legal conclusions with respect thereto, in our opinion fairly and accurately summarize the matters referred to therein in all material respects.

In rendering the opinions in paragraphs (1), (2), (3), (4) and (5) above, we have assumed that each party to the Documents has been duly incorporated and is validly existing under the laws of the jurisdiction of its organization. In addition, we have assumed that (i) the execution, delivery and performance by each party thereto of each Document to which it is a party (a) are within its corporate powers, (b) do not contravene, or constitute a default under, the certificate of incorporation or bylaws or other constitutive documents of such party, (c) require no action by or in respect of, or filing with, any governmental body, agency or official and (d) do not contravene, or constitute a default under, any provision of applicable law or regulation or any judgment, injunction, order or decree or any agreement or other instrument binding upon such party, provided that we make no such assumption to the extent that we have specifically opined as to such matters with respect to the Company and the Guarantor, and (ii) each Document (other than the Underwriting Agreement) is a valid, binding and enforceable agreement of each party thereto (other than as expressly covered above in respect of the Company and the Guarantor).

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 of America, except that we express no opinion as to any law, rule or regulation that is applicable to the Company and the Guarantor, the Documents or such transactions solely because such law, rule or regulation is part of a regulatory regime applicable to any party to any of the Documents or any of its affiliates due to the specific assets or business of such party or such affiliate. With respect to all matters of Spanish law, you have received, and we understand that you are relying upon, the opinions of Uría Menéndez Abogados, S.L.P. and Ramiro Sánchez de Lerín García-Ovies, General Counsel of the Guarantor, each delivered pursuant to the Underwriting Agreement.

Exhibit B to the Underwriting Agreement – 4

This opinion is rendered solely to you in connection with the Underwriting Agreement. This opinion may not be relied upon by you for any other purpose or relied upon by any other person (including any person acquiring Securities from you) or furnished to any other person without our prior written consent.

We have participated in the preparation of the registration statement of the Company and the Guarantor on Form F-3 (File No. 333-204118) (including the documents incorporated by reference therein (the “Incorporated Documents”)) filed with the Securities and Exchange Commission (the “Commission”) pursuant to the provisions of the Securities Act of 1933, as amended (the “Act”), relating to the registration of securities (the “Shelf Securities”) to be issued from time to time by the Company and the Guarantor, and have participated in the preparation of the preliminary prospectus supplement dated April —, 2017 (the “Preliminary Prospectus Supplement”) relating to the Securities, the free writing prospectus dated April —, 2017, identified as Numbers 1 Schedule II to the Underwriting Agreement and attached as Exhibit 1 to Schedule III to the Underwriting Agreement, and the prospectus supplement dated April —, 2017, relating to the Securities (the “Prospectus Supplement”).

We have, without independent inquiry or investigation, assumed that all documents filed with or submitted to the Commission through its Electronic Data Gathering, Analysis and Retrieval (“EDGAR”) system (except for required EDGAR formatting changes) conform to the versions of such documents reviewed by us prior to such formatting.

The primary purpose of our professional engagement was not to establish or confirm factual matters or financial, accounting or quantitative information.

However, in the course of our acting as counsel to the Company and the Guarantor in connection with the preparation of the Registration Statement, the Disclosure Package and the Prospectus, we have generally reviewed and discussed with your representatives and your counsel and with certain officers and employees of, Spanish counsel for, and independent public accountants for, the Company and the Guarantor the information furnished, whether or not subject to our check and verification. We have also reviewed and relied upon certain corporate records and documents, letters from counsel and accountants and oral and written statements of officers and other representatives of the Company and the Guarantor and others as to the existence and consequence of certain factual and other matters.

On the basis of the information gained in the course of the performance of the services rendered above, but without independent check or verification except as stated above:

(i) the Registration Statement and the Prospectus appear on their face to be appropriately responsive in all material respects to the requirements of the Act and the applicable rules and regulations of the Commission thereunder; and

(ii) nothing has come to our attention that causes us to believe that, insofar as relevant to the offering of the Securities:

(a) on the date of the Underwriting Agreement, the Registration Statement contained any untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading,

(b) at — [p.m.], New York City time on April —, 2017, the Disclosure Package contained any untrue statement of a material fact or omitted to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, or

C.    Opinion

We do not represent ourselves to be familiar with the laws of any jurisdiction other than Spain as they stand at present and therefore express no opinion on matters arising under any laws other than the laws of Spain currently in force. This legal opinion is issued on the basis that all related-matters will be governed by, and construed in accordance with Spanish law, and that all matters between the addressee of this legal opinion and ourselves (in particular, those regarding interpretation) will be brought before the Spanish courts.

Exhibit D to the Underwriting Agreement – 4

Our involvement in the transaction described has been limited to our role as Spanish counsel to the Guarantor and the Company, and we therefore assume no obligation to advise any other party to the transaction. Furthermore, we assume no obligation to advise you or any other party of any changes to the law or facts that may occur after today’s date, regardless of whether they affect the legal analysis or conclusions in this legal opinion.

Legal concepts are expressed in the documents in English terms and may not be identical or equivalent to the Spanish legal terms used.

Based on the above, and subject to the additional exceptions, limitations and qualifications set out below, it is our opinion that:

1. Valid existence

Each of the Guarantor and the Company was duly incorporated and validly exist as a “sociedad anónima” under the laws of Spain.

2. Corporate power

Each of the Company and the Guarantor has corporate power to conduct its corporate purpose (including the power to dispose of and encumber its assets) and each of the Company and the Guarantor has the required corporate power to be a party to the Documents and perform the obligations deriving from the same.

3. Corporate action

The execution, delivery and performance of the Documents have been duly authorized by all the necessary corporate actions of the Company and the Guarantor.

4. Valid execution of agreements

Each of the Company and the Guarantor has duly authorized, executed and delivered each of the Documents to which it is a party.

5. Choice of law

The choice of the laws of the State of New York as the governing law of the Documents is valid and should be recognized and enforced by the Spanish courts, subject to the qualification referred to in paragraph D.(f) below. The effectiveness of this choice is subject, in particular, to the laws of the State of New York being evidenced to the Spanish courts pursuant to Article 281 of the Civil Procedural Law and taking into account the contents of article 33 of Law 29/2015 of 30 July on international cooperation in civil matters (“Law 29/2015”).

6. Authorizations and consents

The execution, delivery and performance of the Documents by each of the Company and the Guarantor to which it is a party (a) do not require any consent, approval, licence, authorization, or registration from any Spanish governmental authority, save for the registration of the Public Deed of Issuance with the Commercial Registry of Madrid and (b) do not imply a breach of the articles of association (estatutos) of the Company and the Guarantor. This notwithstanding (i) once the Notes have been paid

Exhibit D to the Underwriting Agreement – 5

in full, this circumstance must be registered at the Commercial Registry of Madrid; and (ii) the Issuer will be required to report the issuance of the Notes to the Bank of Spain pursuant to, and in accordance with, the Circular 4/2012, of April 25 on communication rules applicable to the Spanish residents on foreign economic transactions and financial assets and liabilities (Circular 4/2012, de 25 de abril, del Banco de España, sobre normas para la comunicación por los residentes en España de las transacciones económicas y los saldos de activos y pasivos financieros con el exterior).

7. Tax regime of payments made under the Notes

Additional Provision One of Law 10/2014 of 26 June, on the regulation, supervision and solvency of credit institutions (Ley 10/2014, de 26 de junio, de ordenación, supervisión y solvencia de entidades de crédito), as amended (“Law 10/2014”) establishes the tax regime applicable to certain preference shares and debt instruments.

To the extent that the Issuer is a company resident in Spain, which is not a financial institution or a listed company, the tax regime set forth in Additional Provision One of Law 10/2014 requires, among other conditions, that the Notes qualifies as debt instruments for the Issuer and that the Notes are listed on a regulated market, multilateral trading facility or other organised market. Both conditions are met in the case of the Notes.

Under Law 10/2014, income deriving from the Notes obtained by holders who have a beneficial interest in the Notes (each a “Holder” and collectively the “Holders”) with non-tax residence in Spain and who do not operate with respect to the Notes through a permanent establishment in Spain should be exempt from Spanish Non-Resident Income Tax (“NRIT”). Conversely, income deriving from the Notes obtained by Spanish tax resident Holders and Non-Spanish tax resident Holders acting with respect to the Notes through a permanent establishment in Spain is fully subject to tax in Spain. According to Spanish tax legislation, “income” includes payment of coupons and income deriving from the transfer, redemption or reimbursement of the Notes, on the basis of the positive difference between the amounts obtained in the transfer, redemption or reimbursement of the Notes and their tax basis.

Additionally, under Law 10/2014 all payments of income on the Notes made by the Issuer with respect to the Notes for the benefit of Holders, whether resident or not in Spain for tax purposes, will not be subject to Spanish withholding tax unless the Fiscal Agent fails to timely comply with certain tax formalities, as described in detail below.

The application of the abovementioned exemption from Spanish withholding tax is conditional upon the submission by the Fiscal Agent, in a timely manner, to the Issuer with a certificate containing certain information relating to the Notes in accordance with section 44 of the Royal Decree 1065/2007 as amended by Royal Decree 1145/2011 (“Payment Statement”), as detailed under the Agency Agreement.

The Issuer, the Guarantor and the Fiscal Agent have arranged certain procedures to facilitate the collection of information concerning the Notes so that before the close of business on the business day (as defined in the Conditions) immediately preceding the date on which any payment of income in respect of the Notes is due, the Issuer must receive from the Fiscal Agent the Payment Statement as prescribed under section 44 paragraph 5 of the Royal Decree 1065/2007. If, despite these procedures, the Payment Statement is not received by the Issuer on each date in which any amount is due under the Notes, the Issuer will withhold tax at the then-applicable rate (currently 19%) from any payment of income in respect of the relevant Bond.

Exhibit D to the Underwriting Agreement – 6

Notwithstanding the above, if, before the tenth calendar day of the month following the month in which the relevant income is paid, the Fiscal Agent provides the Payment Statement, the Issuer will reimburse the amounts withheld.

Holders not acting with respect to the Notes through a permanent establishment in Spain and entitled to exemption from NRIT, but the payment to whom was not exempt from Spanish withholding tax due to the failure to deliver by the Fiscal Agent of certain information relating to the Notes in a timely manner may apply directly to the Spanish tax authorities for any refund to which they may be entitled..

8. Tax regime of payments made under the Notes if Law 10/2014 does not apply

If the Notes are not listed on a regulated market, multilateral trading facility or other organized market on any Interest Payment Date (as defined in the Prospectus Supplement) or on any redemption date, Law 10/2014 will not apply to the Notes. In such case, any payment of income in respect of the Notes made by the Company to non-Spanish tax resident beneficial owners who do not operate with respect to the Notes through a permanent establishment in Spain will be subject to Spanish withholding tax at the current rate of 19 %, except in the case of income payments made to non-Spanish tax resident beneficial owners who are (A) resident in a European Union Member State other than Spain, or a permanent establishment located in a European Union Member State of residents of other European Union Member States, provided that such beneficial owners (i) do not operate with respect to the Notes through a permanent establishment in Spain, and (ii) are not resident or nationals of, are not located in, nor obtain the income through, a tax haven territory (as defined in Royal Decree 1080/1991 of July 5, 1991, as amended); or (B) resident for tax purposes in a country which has entered into a convention for the avoidance of double taxation with Spain which provides for an exemption from Spanish tax or a reduced withholding tax rate with respect to interest or other financial income payable to any beneficial owner of the Notes, and provided further that said beneficial owners deliver evidence of their tax residence in accordance with the Spanish tax law.

9. Tax regime of payments made under the Guarantee

In light of the operational arrangement described in Exhibit B to the Supplemental Indentures, income payments in respect of the Guarantee would fall under the scope of Law 10/2014 and, therefore, the tax treatment applicable will be that described in paragraph 7 above.

In the event that the Notes are not listed on a regulated market, multilateral trading facility or other organized market on any Interest Payment Date (as defined in the Prospectus Supplement) or on any redemption date, Law 10/2014 will not apply to the Notes and consequently, such income payments will be subject to the tax treatment described in paragraph 8 above. However, non-Spanish tax resident beneficial owners who do not operate with respect to the Notes through a permanent establishment in Spain may take the position that income payments in respect of the Guarantee should be characterised as an indemnity under Spanish law and, hence, should have been made free of withholding or deduction on account of any Spanish tax. In such a case, these beneficial owners should apply directly to the Spanish tax authorities for any refund to which they may be entitled.

Exhibit D to the Underwriting Agreement – 7

10. Stamp duty and other transfer taxes

No stamp or other issuance or transfer taxes or duties are payable by or on behalf of the Underwriter to Spain or any political subdivision or taxing authority thereof or therein in connection with the sale of the Notes to the Underwriter in the manner contemplated hereby, or the resale and delivery of such Notes by the Underwriter in the manner contemplated in the Prospectus Supplement.

11. Tax Status of Holders of the Notes

Any holder of Notes will not be deemed to be resident in Spain by reason only of holding such Notes.

12. Choice of foreign courts

The Spanish courts will determine the validity of clause 14 of the Standard Provisions of the Underwriting Agreement and clause 1.15 of the Indenture (submission to exclusive jurisdiction) in accordance with the laws of Spain although such agreements are subject to the laws of the State of New York. In view of this, the submission to the exclusive jurisdiction of any federal or state court in the Borough of Manhattan, the City of New York, New York, as set out in clause 14 of the Standard Provisions of the Underwriting Agreement and clause 1.15 of the Indenture, in order to resolve any dispute that could arise is valid and should be recognized and enforced by the Spanish courts in any action or proceedings brought in relation thereto before them, provided that it is alleged in accordance with Spanish procedural law.

13. Execution of foreign judgments

An unappelable judgment duly rendered by any federal or state court in the Borough of Manhattan, the City of New York, New York, in response to a legal action filed before such courts in connection with the Underwriting Agreement, the Indenture and the Supplemental Indenture would be enforceable in Spain, provided that the requirements in Law 29/2015 are complied with.

These provisions set out that any unappelable judgment rendered outside of Spain (apart from countries bound by Regulation (EU) No 1215/2012 of the European Parliament and of the Council of 12 December 2012 on jurisdiction and the recognition and enforcement of judgments in civil and commercial matters) may be enforced in Spain in two different situations: (i) in accordance with any applicable international treaty, or (ii) in the absence of any such treaty, when the requirements in Title V of Law 29/2015, including those applicable to exequatur proceedings, are complied with.

Since there is no applicable treaty between Spain and the United States, the conditions referred to in point (ii) of the previous paragraph must be satisfied in order to enforce an unappealable judgment of a New York court in Spain. These conditions are, among others, that the judgment is not irreconcilable with another earlier judgment issued in Spain or in another country (provided in this latter case that the earlier judgment fulfils the conditions to be recognised in Spain), that there are no prior proceedings on the same matter pending in Spain, that the judgment does not infringe public policy and that the relevant matter does not fall under the exclusive jurisdiction of the Spanish courts.

Exhibit D to the Underwriting Agreement – 8

D.    Qualifications

The opinions above are subject to the following:

(a) our opinions above are subject to the effects and outcome of transactions that may derive from insolvency or any other similar proceedings that affect creditors’ rights generally as well as to any principles of public policy (orden público);

(b) without prejudice to the general qualification set forth in the preceding paragraph, the credit rights of creditors that are considered “closely related” to the insolvent debtor will be subordinated pursuant to article 92.5 of Law 22/2003 of 9 July 2003 on Insolvency (for example, because the creditor holds an interest in the insolvent debtor or is part of the same group, the creditor is a director of the insolvent debtor or may be considered a “de facto” director of the same, or the creditor is the assignee or successor of credit rights previously held by any of the foregoing).

After the amendment of the Insolvency Law pursuant to Royal Decree-Law 3/2009 of March 27, it has been clarified that credit rights against the Company arising from the Notes benefiting of the Guarantee will not be classified as subordinated obligations, provided that the holders of the Notes are not especially related persons;

(c) the above references to the insolvency legislation and other similar proceedings are not exhaustive and there may be other rules which, in one way or the other, may also have an impact on the transaction analyzed;

(d) the term “enforceable” in paragraph C.13 of this opinion means that the obligations assumed by the relevant party under the Documents are of a type that the Spanish courts would generally enforce. However, it does not mean that these obligations will be enforced under all circumstances in accordance with their exact terms. In particular, enforcement before the Spanish courts will be subject to the following:

(a) a Spanish court may refuse to give effect to any provision of the Documents on the grounds that it breaches Spanish public policy (orden público);

(b) the Spanish courts will apply the law subject to the equitable principles and will not acknowledge a right if its exercise would be in breach of good faith or cause an abuse of rights (abuso de derecho). The Spanish courts will not enforce an obligation in the event of fraud;

(c) a Spanish court may award damages where specific performance of an obligation is deemed impracticable;

(d) the validity and performance of contractual obligations cannot be left to the discretion of one of the contracting parties as per article 1,256 of the Spanish Civil Code;

(e) a Spanish court may not enforce a contractual provision that imposes a penalty on one of the parties if it considers that the amount of the penalty is not justified and it falls within the scope of articles 1,152 et seq of the Spanish Civil Code, provided that the obligations secured by the penalty have been partially or irregularly complied with; in this event the court may reduce the amount of the penalty; and

Exhibit D to the Underwriting Agreement – 9

(f) the exercise of the rights arising from the Documents and their enforcement is limited by the applicable statute of limitations.

These principles are of general application, and in applying such principles a court could, among other measures, prohibit a creditor from accelerating the maturity of a debt upon the occurrence of a default deemed immaterial.

(e) in Spanish Procedural law, the rules on the burden of proof in any judicial proceeding cannot be modified by agreement of the parties and, consequently, any provision of the Documents in which decisions, certificates, notifications, opinions or the like carried out by the parties are deemed conclusive evidence in the absence of a manifest error, would not be upheld by a Spanish court. Any document that is not in Spanish must be accompanied by an official sworn translation into Spanish for it to be admissible by a Spanish court or authority;

(f) the choice of the laws of the State of New York in the Documents will not restrict the application of the Spanish “overriding mandatory provisions”, as defined in article 9.1 of Regulation (EC) No 593/2008 of the European Parliament and of the Council of June 17, 2008 on the law applicable to contractual obligations. Furthermore, Spanish courts may refuse to apply a provision of the chosen law if such application is manifestly incompatible with Spanish public policy. Spanish courts may also give effect to the overriding mandatory provisions of the law of the country in which the obligations arising from the contract have been performed or must be performed;

(g) the exclusive jurisdiction of the Spanish courts includes matters relating to the incorporation, validity, nullity and dissolution of companies or legal entities domiciled in Spain, and any decisions and resolutions of their corporate bodies, the validity or nullity of any recordings with a Spanish registry, and the recognition and enforcement of any judgment or arbitration award in Spain that has been obtained in a foreign country; and

(h) our opinion expressed in paragraph C.9 above has been issued under the assumption that the Paying Agent will act in the manner and in accordance with the operational arrangements described in Exhibit B to the Supplemental Indenture.

This legal opinion is rendered to the addressee identified in this letter and in connection with the transactions described above. This legal opinion is not to be used, circulated, quoted or referred to in any other way or for any other purpose, and no persons other than its addressee may make decisions based on it, nor may they claim any liability for its content without our prior written consent.

Yours faithfully,

Rafael Sebastián / Jesús López Tello

(q) Other than as set forth or incorporated by reference in the Registration Statement, the Disclosure Package and the Prospectus, there are no actions, suits or governmental proceedings pending to which the Company, the Guarantor or any subsidiary of the Guarantor is a party or of which any asset of the Company, the Guarantor, or any subsidiary of the Guarantor is the subject which could reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect, or to impair the ability of the Company or the Guarantor to consummate the transactions contemplated hereby; and, to the best of the Guarantor’s knowledge, no such actions, suits or proceedings are threatened or contemplated by any court or governmental, regulatory or stock exchange authority having jurisdiction over the Company, the Guarantor, any Material Subsidiary or any of their respective assets (each a “Governmental Authority”) or any other party, which could reasonably be expected to have a Material Adverse Effect, or to impair the ability of the Company or the Guarantor to consummate the transactions contemplated hereby.

(r) Based on the evaluation of its disclosure controls and procedures performed in conjunction with its Form 20-F filed for the last fiscal year, the Guarantor is

Underwriting Agreement – Standard Provisions – 6

2. Representations and Warranties of the Underwriters.

Each Underwriter represents and warrants, severally and not jointly, to, and agrees with, the Company, the Guarantor and each other Underwriter that:

(a) it has not made, and will not make any offer relating to the Designated Securities that would constitute a “free writing prospectus” (as defined in Rule 405 of the Rules and Regulations) required to be filed with the Commission, other than the information contained in the Term Sheet(s) prepared pursuant to section 5(a) below, without the prior written consent of the Company, the Guarantor and the Representative(s);

the parties or any oral representations or assurances previously or subsequently made by the Underwriters: (i) no fiduciary or agency relationship between the Underwriters, on the one hand, and the Company and the Guarantor, on the other, exists; and (ii) the Underwriters are not acting as advisors, expert or otherwise, to either the Company or the Guarantor, including, without limitation, with respect to the determination of the price of the Designated Securities, and such relationship between the Underwriters, on the one hand, and the Company and the Guarantor, on the other, is entirely and solely commercial, based on arms-length negotiations.

3. Purchase and Sale.

(a) The Company agrees to sell to each Underwriter named in the applicable Underwriting Agreement and each Underwriter, upon the basis of the representations and warranties contained in this Agreement, but subject to the conditions in this Agreement, agrees to purchase from the Company severally and not jointly, the aggregate principal amounts of Designated Securities set forth opposite their names in Schedule I of the applicable Underwriting Agreement at the respective purchase prices set forth in such Underwriting Agreement, plus accrued interest, if any, from the date set forth therein to the date of payment and delivery.

(b) The several commitments of the Underwriters to purchase the Designated Securities pursuant to the applicable Underwriting Agreement shall be deemed to have been made on the basis of the representations, warranties and agreements contained in this Agreement and shall be subject to the terms and conditions set forth in this Agreement.

The global certificates for the Designated Securities to be purchased by the Underwriters shall be delivered by or on behalf of (and at the expense of) the Company to or upon the order of the Underwriters against payment by the Underwriters of the purchase price therefor by wire transfer of immediately available funds, payable to or upon the order of the Company, at the Scheduled Closing Date, as set forth in the applicable Underwriting Agreement, and as the Representative(s) shall designate, which date and time may be postponed by agreement among the Underwriters, the Company and the Guarantor (such date and time of delivery and payment for the Designated Securities being herein called the “Closing Date”). Payment for the Designated Securities shall be made against delivery to the Underwriters of the Designated Securities registered in such names and in such denominations as the Underwriters shall request in writing, with any transfer taxes payable in connection with the transfer of the Designated Securities to the Underwriters duly paid by the Guarantor. The Company agrees that delivery of the Designated Securities will be made on the Closing Date through the book-entry facilities of The Depository Trust Company (“DTC”). Upon issuance, all Designated Securities will be represented by one or more global securities registered in the name of a nominee of the DTC.

5. Covenants and Agreements of the Company and the Guarantor.

The Company and the Guarantor, jointly and severally, covenant with each Underwriter of the Designated Securities as follows:

Underwriting Agreement – Standard Provisions – 8

(a) The Company and the Guarantor will file the Prospectus pursuant to Rule 424(b) of the Rules and Regulations not later than the Commission’s close of business on the second Business Day following the execution and delivery of this Agreement or, if applicable, such earlier time as may be required by Rule 424(b). The Company or the Guarantor will notify the Representative(s), promptly after filing of the Registration Statement, of the time when any amendment to the Registration Statement has been filed or becomes effective or any supplement to the Prospectus or any amended Prospectus has been filed. The Company or the Guarantor will notify the Representative(s) promptly of any request by the Commission for any amendment of or supplement to the Registration Statement or the Prospectus or for additional information; the Company and the Guarantor will prepare and file with the Commission, promptly upon the reasonable request of the Representative(s), any amendments or supplements to the Registration Statement or the Prospectus which, in the reasonable opinion of the Representative(s), may be necessary or advisable in connection with the distribution of the Designated Securities; and neither the Company nor the Guarantor will file any amendment or supplement to the Registration Statement or the Prospectus or file any document under the Exchange Act before the termination of the offering of the Designated Securities by the Underwriters if such document would be deemed to be incorporated by reference into the Prospectus, which filing is not consented to by the Representative(s) after reasonable notice thereof (such consent not to be unreasonably withheld or delayed). The Company and the Guarantor will prepare one or more Term Sheets, containing solely a description of the Designated Securities, substantially in the form attached to the applicable Underwriting Agreement and approved by the Representative(s) and file such Term Sheet or Term Sheets pursuant to Rule 433(d) under the Securities Act within the time period prescribed by such Rule. The Company or the Guarantor will advise the Representative(s) promptly of the issuance by the Commission or any State or other regulatory body of any stop order or other order suspending the effectiveness of the Registration Statement, suspending or preventing the use of any Preliminary Prospectus, the Prospectus or any Issuer Free Writing Prospectus or suspending the qualification of the Designated Securities for offering or sale in any jurisdiction, of the institution of any proceedings for any such purpose, or of receipt by the Company or the Guarantor from the Commission of any notice of objection to the use of the Registration Statement or any post-effective amendment thereto pursuant to Rule 401(g)(2) of the Rules and Regulations; and the Company and the Guarantor will use their reasonable best efforts to prevent the issuance of any stop order or other such order or any such notice of objection and, if a stop order or other such order is issued or any such notice of objection is received, to obtain as soon as practicable the lifting or withdrawal thereof.

(b) Subject to the selling restrictions set forth in Annex A to this Agreement, the Company and the Guarantor will use their reasonable best efforts, in cooperation with the Underwriters, to qualify the Designated Securities for offering and sale under the securities laws of such jurisdictions as the Representative(s) may reasonably request; provided, however, that neither the Company nor the Guarantor shall be obligated to file any general consent to service of process, subject itself to taxation or to qualify as a foreign corporation or as a dealer in securities in any jurisdiction.

(c) The Company and the Guarantor shall prepare the Disclosure Package and the Prospectus in a form approved by the Underwriters, and will promptly furnish the Underwriters with copies of the Registration Statement, the Preliminary

Underwriting Agreement – Standard Provisions – 9

Prospectus, the Term Sheets, any Issuer Free Writing Prospectus and the Prospectus in such quantities as the Underwriters may from time to time reasonably request, and will not file or publish any amendment or supplement to the Registration Statement, the Disclosure Package or the Prospectus, except in accordance with Section 1(f) above, and unless they have furnished a copy to the Underwriters for their review and, except as required by law, will not publish any such proposed amendment or supplement to which the Underwriters reasonably object. If at any time prior to completion of the distribution of the Designated Securities (as determined by the Underwriters) any event occurs as a result of which the Registration Statement, the Disclosure Package or the Prospectus, each as then amended or supplemented, would contain any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, the Company and the Guarantor will promptly so notify the Underwriters. If so notified, the Underwriters shall forthwith suspend any solicitation of offers to purchase Designated Securities and shall cease using the Registration Statement, the Disclosure Package or the Prospectus. If the Company and the Guarantor should decide to amend or supplement the Registration Statement, the Disclosure Package or the Prospectus, as the case may be, to correct such statement or omission, the Company and the Guarantor, upon the completion thereof, will furnish to the Underwriters a reasonable number of copies of such amendment or supplement to the Registration Statement, the Disclosure Package or the Prospectus.

(d) The Company and the Guarantor shall furnish to the Underwriters as soon as practicable and thereafter from time to time prior to the completion of the distribution of the Designated Securities (as determined by the Underwriters) as many copies of the Registration Statement, the Disclosure Package and the Prospectus and any amendments thereof and supplements thereto as the Underwriters may reasonably request.

(e) The Company or the Guarantor will pay the required Commission filing fees relating to the Designated Securities within the time period required by Rule 456(b)(1) of the Rules and Regulations and otherwise in accordance with Rules 456(b) and 457(r) of the Rules and Regulations.

(f) If required by Rule 430B(h) of the Rules and Regulations, the Company or the Guarantor will prepare a prospectus in a form approved by the Representative(s) and file such prospectus pursuant to Rule 424(b) of the Rules and Regulations not later than may be required by such Rule; and, except as required by law or approved by the Representative(s) (which approval shall not be unreasonably withheld), neither the Company nor the Guarantor will make any further amendment or supplement to such prospectus.

(g) The Guarantor will use its reasonable best efforts, and shall cause the Company to use its reasonable best efforts, to ensure that the public deed in respect of the Designated Securities is registered in the Madrid Mercantile Registry.

(h) The Guarantor will use its reasonable best efforts, and shall cause the Company to use its reasonable best efforts, to ensure that the Designated Securities qualify as debt instruments (instrumentos de deuda) under Law 10/2014 of 26 June, or any other law substituting or amending such law.

(i) The Guarantor will use its reasonable best efforts, and shall cause the Company to use its reasonable best efforts, to ensure that the disbursement minutes in respect of the Designated Securities are registered in the Madrid Mercantile Registry.

(j) The Guarantor will use its reasonable best efforts, and shall cause the Company to use its reasonable best efforts, to permit the Designated Securities to be eligible for clearance and settlement through DTC.

(k) The Guarantor will use its reasonable best efforts, and shall cause the Company to use its reasonable best efforts, to list the Designated Securities on an organized market in an OECD country or on a regulated market, multilateral trading facility or other organized market no later than 45 days prior to the first day on which interest on such Designated Securities is payable (the “First Interest Payment Date”) and to maintain such listing at all times prior to and including the First Interest Payment Date.

(l) From the date of the applicable Underwriting Agreement and continuing to and including 10 days following the Closing Date, the Guarantor will not, and shall ensure that the Company does not, without the prior written consent of the Representative(s) (which consent shall not be unreasonably withheld), offer, sell, contract to sell or otherwise dispose of in the United States any U.S. dollar-denominated debt securities issued or guaranteed by the Guarantor which are substantially similar to the Designated Securities.

(m) The Guarantor agrees that for as long as the Designated Securities are outstanding it will maintain sufficient ownership of the share capital of the Company, directly or indirectly, to control its actions.

(n) The Company and the Guarantor acknowledge and agree that in connection with this offering, sale of the Designated Securities or any other services the Underwriters may be deemed to be providing hereunder, notwithstanding any preexisting relationship, advisory or otherwise, between the parties or any oral representations or assurances previously or subsequently made by the Underwriters: (i) no fiduciary or agency relationship between the Company and the Guarantor, on the one hand, and the Underwriters, on the other, exists; (ii) the Underwriters are not acting as advisors, expert or otherwise, to either the Company or the Guarantor, including, without limitation, with respect to the determination of the price of the Designated Securities, and such relationship between the Company and the Guarantor, on the one hand, and the Underwriters, on the other, is entirely and solely commercial, based on arms-length negotiations; (iii) any duties and obligations that the Underwriters may have to the Company or the Guarantor shall be limited to those duties and obligations specifically stated herein; and (iv) the Underwriters and their respective affiliates may have interests that differ from those of the Company and the Guarantor. The Company and the Guarantor hereby waive any claims that the Company or the Guarantor may have against the Underwriters with respect to any breach of fiduciary duty asserted to be owed by the Underwriters to the Company or the Guarantor in connection with this offering.

(b) No Underwriter shall have been advised by the Company or shall have discovered and disclosed to the Company that the Registration Statement, the Disclosure Package or the Prospectus or any amendment or supplement thereto, contains an untrue statement of fact which in the opinion of the Underwriters, or in the opinion of counsel to the Underwriters, is material, or omits to state a fact which, in the opinion of the Underwriters, or in the opinion of counsel to the Underwriters, is material and is required to be stated therein or is necessary to make the statements therein not misleading.

(c) At the Closing Date, if from the Applicable Time to the Closing Date there is no Downgrade Event or Review Event (each as defined below), the Underwriters shall have received a certificate, dated as of the Closing Date, of the Guarantor signed by the deputy chief financial officer of the Guarantor, certifying, with respect to the Guarantor, that at the Closing Date and subsequent to the dates as of which information is given in the Disclosure Package, (i) no stop order suspending the effectiveness of the Registration Statement shall be in effect, and no proceedings for such purpose shall be pending before or threatened by the Commission (ii) there shall not have been any material adverse change in the financial condition, earnings or prospects of the Guarantor and its subsidiaries, considered as one enterprise, (iii) since the Applicable Time, there shall not have been, with respect to the rating of any debt securities or preferred stock of the Guarantor or debt securities or preferred stock unconditionally guaranteed by the Guarantor, a downgrade by Moody’s Investor Services, Inc. (“Moody’s”), Fitch Ratings Ltd. (“Fitch”); or Standard and Poor’s Corporation (“S&P”) (any such event, a “Downgrade Event”), or any public announcement that either Moody’s, Fitch, or S&P has under surveillance or review its rating of any debt securities or preferred stock of the Guarantor or debt securities or preferred stock unconditionally

Underwriting Agreement – Standard Provisions – 12

(f) At the Closing Date, the Underwriters shall have received letters of accountants dated as of the Closing Date, confirming information as specified in the comfort letters delivered pursuant to Section 6(e) above, from those accountants of the Guarantor or any of its subsidiaries as specified in the applicable Underwriting Agreement.

Underwriting Agreement – Standard Provisions – 13

7. Payment of Expenses.

The Guarantor will pay costs and expenses incident to the performance of the Company’s and the Guarantor’s obligations under this Agreement as the parties may separately agree.

8. Indemnification.

(a) The Company and the Guarantor jointly and severally agree to indemnify and hold harmless the Underwriters and each person, if any, who controls an Underwriter within the meaning of Section 15 of the Securities Act as follows: (i) against any and all loss, liability, claim, damage and expense whatsoever, as incurred and reasonably and properly documented, arising out of an untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, any “free writing prospectus” (as defined in Rule 405 of the Rules and Regulations), the Disclosure Package, or the Prospectus (or any amendment or supplement thereto), or the omission or alleged omission therefrom of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; and (ii) against any and all expense whatsoever (including reasonable fees and disbursements of counsel chosen by the Underwriters), reasonably incurred in investigating, preparing or defending against any litigation, or investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission, to the extent that any such expense is not paid under clause (i) above; provided, however, that this indemnity does not apply to any loss, liability, claim, damage or expense to the extent arising out of (A) an untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with information furnished in writing to the Company or the Guarantor by the Underwriters expressly for use in the Registration Statement, any Issuer Free Writing Prospectus, the Disclosure Package or the Prospectus (or any amendment or supplement to the Prospectus) or (B) an untrue statement or omission or alleged untrue statement or omission of a material fact in any Issuer Free Writing Prospectus, any Preliminary Prospectus or the Prospectus (or any amendment or supplement to part of any Issuer Free Writing Prospectus, any Preliminary Prospectus or the Prospectus) delivered to any person if such untrue statement or omission was corrected in any subsequent Issuer Free Writing Prospectus, Preliminary Prospectus or Prospectus or any amendment or supplement thereto, if copies thereof were delivered to such Underwriter sufficiently in advance of the Applicable Time to enable such Underwriter to deliver such copies to such person and a copy thereof was not furnished to such person prior to the confirmation of the sale of Designated Securities to such person.

(b) Each Underwriter severally, but not jointly, agrees to indemnify and hold harmless the Company and the Guarantor, and each person, if any, who controls the Company or the Guarantor, within the meaning of Section 15 of the Securities Act, against any and all loss, liability, claim, damage and expense described in the indemnity contained in Section 8(a), as incurred, but only with respect to untrue statements or omissions, or alleged untrue statements or omissions, made in any Issuer Free Writing Prospectus, the Disclosure Package or the Prospectus (or any amendment or supplement to the Prospectus), in reliance upon and in conformity with information furnished in writing to the Company or the Guarantor by the Underwriters expressly for use in such Issuer Free Writing Prospectus, Disclosure Package or Prospectus (or any amendment or supplement to the Prospectus).

Underwriting Agreement – Standard Provisions – 14

(c) Promptly after receipt by an indemnified party under this Section 8 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under subsection (a) or (b) above, notify the indemnifying party of the commencement thereof; but the omission so to notify the indemnifying party will not relieve it from any liability which it may have to any indemnified party under subsection (a) or (b) above except to the extent that it has been materially prejudiced (through forfeiture or impairment of procedural or substantive rights or defenses) by such failure; and provided further that the failure to notify the indemnifying party shall not relieve it from any liability that it may have to an indemnified party otherwise than under subsection (a) or (b) above. In case any such action is brought against any indemnified party and it notifies the indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein and, to the extent that it may wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel reasonably satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party will not be liable to such indemnified party under this Section 8 for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation; provided, however, that the indemnified party shall have the right to employ counsel to represent the indemnified party and their respective controlling persons who may be subject to liability arising out of any claim in respect of which indemnity may be sought by the indemnified party against the indemnifying party under this Section 8 if the employment of such counsel shall have been authorized in writing by the indemnifying party in connection with the defense of such action, if in the written opinion of counsel to either the indemnifying party or the indemnified party, representation of both parties by the same counsel would be inappropriate due to actual or likely conflicts of interest between them or the indemnifying party shall have failed to employ counsel within a reasonable period of time, and in that event the fees and expenses of one firm of separate counsel (in addition to the fees and expenses of one local counsel in each applicable jurisdiction) shall be paid by the indemnifying party. No indemnifying party shall, without the prior written consent of the indemnified party (which consent shall not be unreasonably withheld), effect any settlement of any pending or threatened action in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party unless such settlement (i) includes an unconditional release of such indemnified party from all liability on any claims that are the subject matter of such action and (ii) does not include a statement as to or an admission of fault, culpability or failure to act by or on behalf of any indemnified party. The indemnified party shall not be liable for any settlement of any proceeding effected without its written consent.

9. Contribution.

If the indemnification provided for in Section 8 is unavailable or insufficient to hold harmless an indemnified party under subsection (a) or (b) of Section 8, then each indemnifying party shall contribute to the amount paid or payable by such

Underwriting Agreement – Standard Provisions – 15

indemnified party as a result of the losses, claims, damages or liabilities referred to in subsection (a) or (b) of Section 8, (i) in such proportion as is appropriate to reflect the relative benefits received by the Company and the Guarantor, on the one hand, and the Underwriters, on the other, from the offering of the Designated Securities or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company and the Guarantor, on the one hand, and the Underwriters, on the other, in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities as well as any other relevant equitable considerations. The relative benefits received by the Company and the Guarantor, on the one hand, and the Underwriters, on the other, shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Company bear to the total discounts and commissions received by the Underwriters from the Company under this Agreement. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or the Guarantor or the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The Company, the Guarantor and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 9 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to above in this Section 9. The amount paid by an indemnified party as a result of the losses, claims, damages or liabilities referred to in the first sentence of this Section 9 shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any action or claim which is the subject of this Section 9. Notwithstanding the provisions of this Section 9, no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Designated Securities purchased by it were resold exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations in this Section 9 to contribute are several in proportion to their respective purchase obligations and not joint.

10. Representations, Warranties and Agreements.

The representations, warranties, indemnities, agreements and other statements of the Underwriters, the Company and the Guarantor and their officers set forth in or made pursuant to this Agreement will remain operative and in full force and effect regardless of any investigation made by or on behalf of the Company, the Guarantor or the Underwriters or controlling person and will survive delivery of and payment for the Designated Securities.

11. Termination of Agreement.

(a) The Underwriters may terminate this Agreement, by notice to the Company or the Guarantor, at any time at or prior to the Closing Date:

(i) if there has been, since the Applicable Time, except as otherwise set forth or contemplated by the Registration Statement, the Disclosure

Underwriting Agreement – Standard Provisions – 16

Package and the Prospectus, any change, or any development (other than as set forth in or contemplated by the Registration Statement, the Disclosure Package and the Prospectus), in the financial condition, earnings or prospects of the Guarantor and its subsidiaries, considered as one enterprise, which, in the judgment of the Representative(s), is material and adverse in the context of the issuance, offer and sale of the Designated Securities and makes it impracticable or inadvisable to proceed with completion of the offering or the sale of and payment for the Designated Securities; or

(ii) if, since the Applicable Time there has occurred:

(A) any material suspension or material limitation of trading in securities generally on the New York Stock Exchange or in the over-the counter market or minimum or maximum prices for trading have been fixed, or maximum ranges for prices for securities have been required by such exchange or by order of the Commission, or any other Governmental Authority, or

(B) any material suspension of trading of any equity securities issued by the Guarantor by the Commission, the Comisión Nacional del Mercado de Valores, the Spanish Stock Exchanges or the New York Stock Exchange, or

(C) any banking moratorium declared by Spanish, United States Federal or New York State authorities, or

(D) any major disruption of settlements of securities or clearance services in the United States or with respect to DTC, or

(E) any change or any development involving a prospective change in national or international political, financial or economic conditions or exchange controls which, in the judgment of the Representative(s), makes it impracticable or inadvisable to proceed with the completion of the offering or sale of and payment for the Designated Securities, or

(F) any attack on, or outbreak or escalation of hostilities or act of terrorism involving the United States, any declaration of war by the United States Congress or any other substantial calamity or emergency if, in the judgment of the Representative(s), the effect of any such attack, outbreak, escalation, act, declaration, calamity or emergency makes it impracticable or inadvisable to proceed with completion of the offering or sale of and payment for the Designated Securities.

(b) If the Underwriters propose to terminate this Agreement pursuant to Sections 11(a)(i), 11(a)(ii)(E) or 11(a)(ii)(F), the Representative(s) shall enter into consultations with the Guarantor by telephone. Such consultation shall take place among one senior representative of each of the Representative(s) and the Guarantor. The senior representative(s) of the Representative(s) will explain in depth the basis of their determination and the senior representative of the Guarantor will relay the views of the Company and the Guarantor to the

Underwriting Agreement – Standard Provisions – 17

Representative(s). If no such consultation takes place within a time period as reasonably determined by the Representative(s) to be appropriate, despite the best efforts of the Representative(s) to reach the senior representative of the Guarantor, or if no consensus can be reached during that period, the Representative(s) may (unanimously, if there is more than one Representative), in the name of the Underwriters, effect the termination of the obligations of the Underwriters under this Agreement.
