As Representatives of the several Underwriters

Ladies and Gentlemen:

Abengoa, S.A., a corporation organized under the laws of the Kingdom of Spain (“Spain”) (the “Company”), proposes to issue and sell to the several Underwriters, for whom you (the “Representatives”) are acting as representatives, [·] Class B shares, €0.01 par value each (such class of shares, the “Class B Shares”), of the Company (said shares to be issued and sold by the Company being hereinafter called the “Underwritten Shares”). The Company also proposes to sell up to [·] additional Class B Shares to the Underwriters to cover over-allotments, if any (the “Option Shares” and together with the Underwritten Shares, the “Offered Shares”), in accordance with Section 2 hereof.

The Representatives have also advised the Company that the Underwriters may elect to cause the Company to deposit on their behalf all or any portion of the Offered Shares to be purchased by them hereunder pursuant to the Deposit Agreement, dated as of [·], 2013 (the “Deposit Agreement”), to be entered into among the Company, Citibank, N.A., as depositary (the “Depositary”) and all holders from time to time of the ADSs (as hereinafter defined). Upon deposit of any Class B Shares, the Depositary will issue American Depositary Shares (the “ADSs”) representing the Class B Shares so deposited. The ADSs will be evidenced by American Depositary Receipts (the “ADRs”). Each ADS will represent [·] Class B Shares and each ADR may represent any number of ADSs. Unless the context otherwise requires, the terms “Underwritten Shares,” “Option Shares” and “Offered Shares,” shall be deemed to refer, respectively, to Underwritten Shares, Option Shares and Offered Shares as well as, in each case, to any ADSs representing such securities and the ADRs evidencing such ADSs.

To the extent there are no additional Underwriters listed on Schedule I other than you, the term Representatives as used in this Underwriting Agreement shall mean you, as Underwriters, and the terms Representatives and Underwriters shall mean either the singular or plural as the context requires. The use of the neuter in this Underwriting Agreement shall include the feminine and masculine wherever appropriate. Certain terms used in this Underwriting Agreement are defined in Section 23 hereof.

1. Representations and Warranties. The Company represents and warrants to, and agrees with, each Underwriter as set forth below in this Section 1.

(a) The Company has prepared and filed with the Commission the Registration Statement (as hereinafter defined), including related preliminary prospectuses, for registration under the Act of the offering and sale of the Securities (as hereinafter defined) being offered in the United States. Such Registration Statement, including any amendments thereto filed prior to the Execution Time, has become effective. The Company may have filed one or more amendments thereto, including the related preliminary prospectuses, each of which has previously been furnished to you. The Company will file with the Commission a final prospectus in accordance with Rule 424(b). As filed, such final prospectus shall contain all information required by the Act and the rules thereunder and, except to the extent the Representatives shall agree in writing to a modification, shall be in all substantive respects in the form furnished to you prior to the Execution Time or, to the extent not completed at the Execution Time, shall contain only such specific additional information and other changes (beyond that contained in the latest Preliminary Prospectus (as hereinafter defined)) as the Company has advised you, prior to the Execution Time, will be included or made therein.

It is understood that two forms of prospectuses are to be used in connection with the offering and sale of the Offered Shares: the Prospectus relating to the offering and sale of the Securities in the United States and outside the United States (other than in Canada) and a prospectus relating to the offering and sale of the Securities in Canada (the “Canadian Prospectus”). The Prospectus and the Canadian Prospectus contain substantially identical information except for certain substitute or additional pages. Unless the context otherwise requires, references herein to the “Prospectus” whether in preliminary or final form and whether as amended or supplemented, shall include the two versions thereof referred to in this paragraph.

(b) The Company has prepared and filed with the CNMV on July 12, 2012 a registration document (documento de registro) (the “Documento de Registro”) pursuant to Annexes I and II of Commission Regulation (EC) No. 809/2004, in the Spanish language for approval and registration under the Spanish Act (as hereinafter defined). Such Documento de Registro was approved and registered by the CNMV on its official files on July 12, 2012 (file number 2012/10,185) and has not been supplemented thereafter. In addition, the Company filed a relevant fact notice (comunicación de hecho relevante) concerning the Securities (the “Relevant Fact Notice”) with the CNMV on [·], 2013, which was registered by the CNMV on its official files under file number [·]. The Company will prepare and file with the CNMV on [·] a securities note (nota sobre las acciones), in the Spanish language, pursuant to Annex III of Commission Regulation (EC) No. 809/2004 (the “Nota sobre las Acciones”), including a summary note (resumen) that, together with the Documento de Registro, will constitute the

informative prospectus (folleto informativo) (the “Folleto”) required to be filed and registered by the Company with the CNMV in connection with its application for admission to listing of the Offered Shares on the Madrid and Barcelona Stock Exchanges for trading through the SIB (as hereinafter defined). The Relevant Fact Notice and the Folleto are hereto referred to as the “Spanish Documents.”

The Spanish Documents, as of their dates and as of the Execution Time, did not and will not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein not misleading; and on the date of any amendment or supplement and on the Closing Date, the Settlement Date and the Option Closing Date, if any, the Folleto (together with any supplement thereto) will not include any untrue statement of a material fact or omit 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; provided, however, that the Company makes no representations or warranties as to the information contained in or omitted from the Folleto (or any supplement thereto) in reliance upon and in conformity with information furnished in writing to the Company by or on behalf of any Underwriter through the Representatives specifically for inclusion in the Folleto, it being understood and agreed that the only such information furnished by or on behalf of any Underwriter consists of the information described as such in Section 8(b) hereof.

(y) No holders of securities of the Company have rights to the registration of such securities under the Registration Statement, the ADR Registration Statement and the Spanish Documents.

(z) The consolidated historical financial statements and the related notes of the Company and its consolidated subsidiaries included in the Disclosure Package, the Prospectus, the Registration Statement and the Folleto present fairly the financial condition, results of operations and cash flows of the Company as of the dates and for the periods indicated, comply as to form with the applicable accounting requirements of the Act and have been prepared in accordance with IFRS as issued by the IASB (as such terms are defined herein), in the case of the Disclosure Package, the Prospectus and the Registration Statement, and IFRS as adopted by the European Union, in the case of the Folleto, in each case applied on a consistent basis throughout the periods involved. The selected financial data set forth under the captions “Summary Consolidated Financial Information” and “Selected Consolidated Financial Information” in each Preliminary Prospectus and the Prospectus and in Section 3 of the Documento de Registro and Section 11.2 of the Nota sobre las Acciones fairly present, on

the basis stated in each Preliminary Prospectus, the Prospectus and the Folleto, the information included therein. The interim financial data set forth under the caption “Recent Developments” in the Disclosure Package and the Prospectus and in Section 11.3 of the Nota sobre las Acciones, was prepared in accordance with IFRS as issued by the IASB, applied on a consistent basis as the consolidated historical financial statements and the related notes of the Company and its consolidated subsidiaries included in the Disclosure Package, the Prospectus, the Registration Statement and the Folleto, as applicable. The selected financial data and any other historical financial data regarding the Company and its subsidiaries included in the Disclosure Package, the Prospectus, the Registration Statement and the Spanish Documents have been correctly extracted, derived or recalculated from, and have been compiled on a basis consistent with, the audited consolidated financial statements of the Company or the accounting records of the Company. The pro forma financial statements included in the Disclosure Package, the Prospectus, the Registration Statement and the Nota sobre las Acciones present fairly the information shown therein and include assumptions that provide a reasonable basis for presenting the significant effects directly attributable to the transactions and events described therein, the related pro forma adjustments give appropriate effect to those assumptions, and the pro forma adjustments reflect the proper application of those adjustments to the historical financial statement amounts in the pro forma financial statements included in the Disclosure Package, the Prospectus, the Registration Statement and the Nota sobre las Acciones. The pro forma financial statements included in the Disclosure Package, the Prospectus and the Registration Statement comply as to form in all material respects with the applicable accounting requirements of Regulation S-X under the Act. The pro forma financial statements and the related notes thereto and the other pro forma and as-adjusted information included in the Nota sobre las Acciones have been prepared in accordance with the disclosure rules and guidelines of Annex II of Commission Regulation (EC) No. 809/2004 and have been properly compiled on the bases described therein.

(aa) The targets set forth in each Preliminary Prospectus and the Prospectus under the caption “Business—Certain Financial Targets” [and in the Nota sobre las Acciones in Section [·] under the heading [·]], respectively, have been calculated after due, careful and proper inquiry and consideration by the Company, and represent reasonable and fair expectations honestly held by the Company based on all relevant material information known to the Company as of the date of their use. All assumptions on which such targets are based are reasonable.

(bb) The statements set forth in each Preliminary Prospectus and the Prospectus under the caption “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources” and in the Nota sobre las Acciones in Section [3.1] under the heading “Declaración del capital de explotación,” respectively, accurately and fully describe all material trends, demands, commitments and events that the Company believes would materially affect liquidity and are reasonably likely to occur. The Company is not aware of any circumstances now existing or likely to arise that are likely to cause the Company not to have adequate working capital to finance its operations and the operations of its consolidated subsidiaries, in each case for a period of 12 months from the Effective Date. Taking into account the existing cash resources and other facilities available to the Company (and disregarding the proceeds from the issuance and sale of the Securities), the

Company believes that the working capital available to the Company is sufficient for its present requirements and for at least the 12 months following the Effective Date. The cash flow and working capital projections on which the Company has based its statement regarding the sufficiency of its working capital have been properly prepared after due and careful enquiry and take into account all relevant material information concerning the Company. All assumptions on which such projections are based are reasonable, and there are no other material assumptions that should reasonably be taken into account in the preparation of such projections.

(cc) Since the date of the most recent financial statements included in the Disclosure Package, the Prospectus, the Registration Statement and the Spanish Documents (exclusive of any amendment or supplement thereto), there has been no material adverse effect on the condition (financial or otherwise), prospects, earnings, business or properties of the Company and its subsidiaries, taken as a whole, whether or not arising from transactions in the ordinary course of business (a “Material Adverse Effect”), except as set forth in or contemplated in the Disclosure Package, the Prospectus, the Registration Statement and the Folleto (exclusive of any amendment or supplement thereto).

(dd) No action, suit or proceeding by or before any court or governmental agency, authority or body or any arbitrator involving the Company or any of its subsidiaries or its or their property is pending or, to the best knowledge of the Company, threatened that (i) could reasonably be expected to have a material adverse effect on the performance of this Underwriting Agreement or the consummation of any of the transactions contemplated hereby or (ii) could reasonably be expected to have a Material Adverse Effect, except as set forth in the Disclosure Package, the Prospectus and the Spanish Documents (exclusive of any amendment or supplement thereto).

(ee) Except as otherwise set forth in the Disclosure Package, the Prospectus and the Spanish Documents (exclusive of any amendment or supplement thereto), each of the Company and each of its subsidiaries lawfully owns or leases all such properties as are necessary to the conduct of its operations as presently conducted and such properties are free of any encumbrance.

(hh) Except as otherwise set forth in the Disclosure Package, the Prospectus and the Spanish Documents (exclusive of any amendment or supplement thereto), there are no acquisitions or disposals of businesses or assets by the Company or its subsidiaries pending or currently being negotiated which would be or might reasonably be expected to be material in the context of the issue of the Offered Shares or which might require a public announcement to be made by the Company.

(ii) Except as otherwise set forth in the Disclosure Package, the Prospectus and the Spanish Documents (exclusive of any amendment or supplement thereto), neither the Company nor any of its subsidiaries has any material off balance sheet financing.

There are no further transactions or agreements that would be required to be described in the Disclosure Package, the Prospectus, the Registration Statement or the Spanish Documents under applicable laws that have not been so described. None of the Company or any of its subsidiaries has since January 1, 2010 or is currently engaged in any material transactions with its directors, officers, management, shareholders, or any other person, including persons formerly holding such positions, on terms that are not available from other parties on an arm’s-length basis.

(ww) Neither the Company nor any of its subsidiaries nor, to the knowledge of the Company, any of its affiliates or any person acting on its or their behalf (other than the Underwriters, as to whom the Company makes no representation) has taken, or will take, directly or indirectly, any action designed to or that would constitute or that might reasonably

be expected to cause or result in, under the Exchange Act or otherwise, stabilization or manipulation of the price of any security of the Company to facilitate the sale or resale of the Offered Shares.

(xx) Neither the Company nor any of its subsidiaries nor, to the knowledge of the Company, any of its affiliates has, directly or indirectly, in relation to the offering contemplated pursuant to this Underwriting Agreement or otherwise, done any act or engaged in any course of conduct in breach of applicable Spanish regulations on market abuse including the Spanish Act as developed by Royal Decree 1333/2005 (Real Decreto 1333/2005, de 11 de noviembre, por el que se desarrolla ▇▇ ▇▇▇ ▇▇/▇▇▇▇, ▇▇ ▇▇ ▇▇ ▇▇▇▇▇, ▇▇▇ ▇▇▇▇▇▇▇ ▇▇ ▇▇▇▇▇▇▇, en materia de abuso ▇▇ ▇▇▇▇▇▇▇), or, to the knowledge of the Company, the equivalent provisions under the securities laws applicable in any other relevant jurisdiction nor, so far as the Company is aware, has any person acting on its behalf or on behalf of any of its affiliates (other than the Underwriters, as to whom the Company makes no representation) done any act or engaged in any course of conduct as described above. The Company has suspended the effectiveness of its liquidity agreement entered into with Santander Investment Bolsa, S.V., S.A. on November 8, 2012 from the date immediately following approval and registration of the Nota sobre las Acciones with the CNMV until the end of the stabilization period provided for in Section 2 hereof.

(yy) Except as otherwise set forth in the Disclosure Package, the Prospectus and the Spanish Documents (exclusive of any amendment or supplement thereto), the Company and its subsidiaries (i) are in compliance with any and all applicable European Union, state, local and foreign law (including U.S. federal and state law) and regulations relating to the protection of human health and safety, the environment or hazardous or toxic substances or wastes, pollutants or contaminants (“Environmental Laws”), (ii) have received and are in compliance with all permits, licenses or other approvals required of them under applicable Environmental Laws to conduct their respective businesses and (iii) have not received written notice of any actual or potential liability under any environmental law, except where such non-compliance with Environmental Laws, failure to receive required permits, licenses or other approvals, or liability would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect. Except as set forth in the Disclosure Package, the Prospectus and the Spanish Documents (exclusive of any amendment or supplement thereto), neither the Company nor any of the subsidiaries has been named as a “potentially responsible party” under the Comprehensive Environmental Response, Compensation, and Liability Act of 1980, as amended.

(zz) Each benefit, pension and compensation plan, agreement, policy and arrangement that is maintained, administered or contributed to by the Company or any of its subsidiaries or any of their respective affiliates for current or former employees or directors of, or independent contractors with respect to, the Company or any of its subsidiaries or any of their respective affiliates, or with respect to which any of such entities could reasonably be expected to have any current, future or contingent liability or responsibility, has been maintained in compliance with its terms and requirements of any applicable statutes, orders, rules and regulations. The Company and each of its subsidiaries and each of their respective affiliates have complied with all applicable statutes, orders, rules and regulations in regard to such plans, agreements, policies and arrangements. The present value of all accrued benefits

under each such plan, based on those assumptions used to fund such plan, as calculated by the Company’s actuaries, did not, as of the last annual valuation date prior to the date on which this representation is made, exceed the value of the assets of such plan allocable to such benefits by an amount which could reasonably be expected to have a Material Adverse Effect. The liabilities reflected on the relevant entity’s financial statements with respect to each such plan, agreement, policy and arrangement which is not required or intended to be funded accurately reflects the present value of all benefits earned or accrued or payments due under such plan, agreement, policy or arrangement determined using reasonable actuarial assumptions.

(aaa) In the ordinary course of its business, the Company periodically reviews the effect of Environmental Laws on the business, operations and properties of the Company and its subsidiaries, in the course of which it identifies and evaluates associated costs and liabilities (including, without limitation, any capital or operating expenditures required for clean-up, closure of properties or compliance with Environmental Laws, or any permit, license or approval, any related constraints on operating activities and any potential liabilities to third parties). On the basis of such review, the Company has reasonably concluded that such associated costs and liabilities would not, singly or in the aggregate, have a Material Adverse Effect, except as set forth in the Disclosure Package, the Prospectus and the Spanish Documents (exclusive of any amendment or supplement thereto).

(bbb) None of the following events has occurred or exists: (i) a failure to fulfill the obligations, if any, under the minimum funding standards of ▇▇▇▇▇▇▇ ▇▇▇ ▇▇ ▇▇▇ ▇▇▇▇▇▇ ▇▇▇▇▇▇ Employee Retirement Income Security Act of 1974, as amended (“ERISA”), and the regulations and published interpretations thereunder with respect to a Plan, determined without regard to any waiver of such obligations or extension of any amortization period; (ii) an audit or investigation by the Internal Revenue Service, the U.S. Department of Labor, the Pension Benefit Guaranty Corporation or any other federal or state governmental agency or any foreign regulatory agency with respect to the employment or compensation of employees by any of the Company or any of its subsidiaries that could have a Material Adverse Effect; (iii) any breach of any contractual obligation, or any violation of law or applicable qualification standards, with respect to the employment or compensation of employees by the Company or any of its subsidiaries that could have a Material Adverse Effect.

(ccc) There is and has been no failure on the part of the Company nor, to the Company’s knowledge, any of the Company’s directors or officers, in their capacities as such, to comply with any provision of the ▇▇▇▇▇▇▇▇-▇▇▇▇▇ Act of 2002 and the applicable rules and regulations promulgated in connection therewith (the “▇▇▇▇▇▇▇▇-▇▇▇▇▇ Act”), including Section 402 relating to loans.

(ddd) Neither the Company nor any of its subsidiaries nor, to the knowledge of the Company, any director, officer, agent, employee or affiliate of the Company or any of its subsidiaries is aware of or has taken any action, directly or indirectly, that would result in a violation by such persons of the Foreign Corrupt Practices Act of 1977, as amended, and the rules and regulations thereunder (the “FCPA”) or of any other applicable law in any applicable jurisdiction which is broadly equivalent to the FCPA or which has as its objective the prevention of corruption, including, without limitation, making use of the mails or any

means or instrumentality of interstate commerce corruptly in furtherance of an offer, payment, promise to pay or authorization of the payment of any money, or other property, gift, promise to give, or authorization of the giving of anything of value to any “foreign official” (as such term is defined in the FCPA) or any foreign political party or official thereof or any candidate for foreign political office, in contravention of the FCPA; and the Company, its subsidiaries and, to the knowledge of the Company, its affiliates have conducted their businesses in compliance with the FCPA and any other applicable law in any applicable jurisdiction which is broadly equivalent to the FCPA or which has as its objective the prevention of corruption and have instituted and maintain policies and procedures designed to ensure, and which are reasonably expected to continue to ensure, continued compliance therewith.

(eee) None of the Company, any of its subsidiaries nor, so far as the Company is aware, any director, officer, agent or employee of the Company or any of its subsidiaries or, to the best of the Company’s knowledge, any person acting on its or their behalf has: (i) used, or agreed to use, any corporate funds for any unlawful contribution, gift, entertainment or unlawful expense relating to political activity; (ii) made, or agreed to make, any offer, payment, promise to pay, or authorization of the payment of any money, or offer, gift, promise to give, or authorization of the giving of anything of value to any official or employee of any foreign or domestic government or public international organization (or person acting in an official capacity for or on behalf of any such government or organization) from, in each case, corporate funds or assets; or (iii) paid, or attempted to pay, any bribe, rebate, pay-off, influence payment, kickback or other unlawful payment.

(fff) The operations of the Company and its subsidiaries are and have been conducted at all times in compliance with applicable financial recordkeeping and reporting requirements and the money laundering statutes and the rules and regulations thereunder and any related or similar rules, regulations or guidelines, issued, administered or enforced by any governmental agency (collectively, the “Money Laundering Laws”) and no action, suit or proceeding by or before any court or governmental agency, authority or body or any arbitrator involving the Company or any of its subsidiaries with respect to the Money Laundering Laws is pending or, to the best knowledge of the Company, threatened.

(ggg) Neither the Company nor any of its subsidiaries nor, to the knowledge of the Company, any director, officer, agent, employee or affiliate of the Company or any of its subsidiaries is currently subject to any sanctions administered by the Office of Foreign Assets Control of the U.S. Treasury Department (“OFAC”); and the Company will not directly or indirectly use the proceeds of the offering, or lend, contribute or otherwise make available such proceeds to any subsidiary, joint venture partner or other person or entity, for the purpose of financing the activities of any person currently subject to any U.S. sanctions administered by OFAC.

(hhh) The Company and its subsidiaries own or possess adequate licenses or have other rights to use, on reasonable terms, all patents, patent applications, trade and service marks, trade and service ▇▇▇▇ registrations, trade names, copyrights, licenses, inventions, trade secrets, technology, know-how and other intellectual property (collectively, the “Intellectual Property”) necessary for the conduct of the Company’s business as now conducted or as proposed in the Prospectus to be conducted. Except as set forth in the

Disclosure Package, the Prospectus and the Spanish Documents (exclusive of any amendment or supplement thereto), (i) there are no rights of third parties to any such Intellectual Property, except for customary reversionary rights of third-party licensors; (ii) there is no material infringement by third parties of any such Intellectual Property that is disclosed in the Registration Statement, the Disclosure Package, the Prospectus and the Spanish Documents as owned by the Company or its subsidiaries; (iii) there is no pending or, to the Company’s best knowledge, threatened action, suit, proceeding or claim by others (A) challenging the Company’s rights in or to any such Intellectual Property, and the Company is unaware of any facts which would form a reasonable basis for any such claim; (B) challenging the validity or scope of any such Intellectual Property, and the Company is unaware of any facts which would form a reasonable basis for any such claim; or (C) that the Company infringes or otherwise violates any patent, trademark, copyright, trade secret or other proprietary rights of others, and the Company is unaware of any other fact which would form a reasonable basis for any such claim; and (iv) there is no prior art of which the Company is aware that may render any U.S. patent held by the Company invalid or any U.S. patent application held by the Company unpatentable which has not been disclosed to the U.S. Patent and Trademark Office.

(jjj) Neither the Company nor any of its subsidiaries nor any of its or their properties or assets has any immunity from the jurisdiction of any court or from any legal process (whether through service or notice, attachment prior to judgment, attachment in aid of execution or otherwise) under the laws of Spain.

(kkk) The Company was not a Passive Foreign Investment Company (“PFIC”) within the meaning of Section 1297 of the United States Internal Revenue Code of 1986, as amended, for its most recent taxable year, believes that it will not be a PFIC for its current taxable year and, based on the Company’s current and projected income, assets and activities, it does not expect to be classified as a PFIC in the foreseeable future.

(lll) The Company is not and, after giving effect to the offering and sale of the Securities and the application of the proceeds thereof as described in the Disclosure Package and the Prospectus, will not be an “investment company” as defined in the Investment Company Act of 1940, as amended.

Any certificate signed by any officer of the Company and delivered to the Representatives or counsel for the Underwriters in connection with the offering of the Offered

Shares shall be deemed a representation and warranty by the Company, as to matters covered thereby, to each Underwriter.

2. Purchase and Sale. (a) Subject to the terms and conditions and in reliance upon the representations and warranties set forth in this Underwriting Agreement, the Company agrees, on the Closing Date, to issue and sell to each Underwriter, and each Underwriter agrees, severally and not jointly, to purchase from the Company, at a purchase price of €[·] per Class B Share (the “Purchase Price”), the amount of the Underwritten Shares, in the form of Class B Shares or ADSs, set forth opposite such Underwriter’s name in Schedule I to this Underwriting Agreement. In connection with the offering, each Underwriter and any controlling entities and/or any of its affiliates acting as an investor for its own account may take up Underwritten Shares and in that capacity may retain, purchase or sell for its own account such Underwritten Shares and any securities of the Company or related investments and may offer or sell such securities or other investments otherwise than in connection with the offering. Accordingly, references herein or in the Disclosure Package, the Prospectus, the Spanish Documents or the Folleto to the Underwritten Shares being offered or placed should be read as including any offering or placement of such Underwritten Shares to the Underwriters and any relevant affiliate acting in such capacity. The Underwriters do not intend to disclose the extent of any such investment or transactions otherwise than in accordance with any legal or regulatory obligation to do so.

(b) Subject to the terms and conditions and in reliance upon the representations and warranties set forth in this Underwriting Agreement, the Company hereby grants an option to the several Underwriters to purchase, severally and not jointly, up to [·] Option Shares at the Purchase Price. Said option (the “Over-allotment Option”) may be exercised only to cover over-allotments in the sale of the Underwritten Shares by the Underwriters. The Over-allotment Option may be exercised by the Representatives, on behalf of the Underwriters, in whole or in part, only once, at any time on or before the 30th day after the date of this Underwriting Agreement upon written or telegraphic notice by the Representatives to the Company setting forth the number of shares of the Option Shares as to which the several Underwriters are exercising the Over-allotment Option and the date on which such Option Shares are to be subscribed and paid for (any such date, an “Option Closing Date”). The number of Option Shares to be purchased by each Underwriter shall be the same percentage of the total number of shares of the Option Shares to be purchased by the several Underwriters as such Underwriter is purchasing of the Underwritten Shares, subject to such adjustments as you in your absolute discretion shall make to eliminate any fractional shares.

(c) With respect to all or any portion of the Offered Shares to be purchased by the Underwriters pursuant to Sections 2(a) and 2(b), the Representatives, on behalf of the Underwriters, may elect to have ADSs delivered and paid for hereunder in lieu of, and in satisfaction of, the Company’s obligation to sell to the Underwriters, and the Underwriters’ several obligation to purchase, such Offered Shares.

(d) In consideration of the agreements herein by the Underwriters, the Company will, in accordance with the provisions of this Underwriting Agreement, no later than the Closing Time (or, with respect to the Option Shares (if the option provided for in Section 2(b) hereof shall have been exercised after the date of this Underwriting Agreement), the Option Closing Date), pay to the Underwriters an aggregate underwriting

commission of 4.5% of the amount equal to the Purchase Price multiplied by the aggregate number of Class B Shares purchased hereunder pursuant to Section 2(a) and 2(b), together with any VAT or other similar tax chargeable thereon.

(e) All sums payable by the Company under this Underwriting Agreement shall be paid without set-off or counterclaim, and free and clear of and without deduction or withholding for or on account of any present or future taxes, levies, imposts, duties, fees, assessments or other charges of whatever nature imposed by Spain, or by any department, agency or other political subdivision or taxing authority thereof, and all interest, penalties or similar liabilities with respect thereto (“Taxes”), unless such deduction or withholding is required by law. If any Taxes are required by law to be deducted or withheld in connection with any such payment, and only in the case of payments made to an Underwriter which is resident for tax purposes in a country that has entered into a Double Tax Treaty with Spain and is not acting through a permanent establishment in a Spanish territory through which it will be acting for the purposes of this Underwriting Agreement, the Company will increase the amount payable as may be necessary in order that the net amount of such payment received by the relevant Underwriter after the deduction or withholding shall equal the respective amount that would have been received by such Underwriter in the absence of the deduction or withholding. No additional amounts shall be payable hereunder by the Company to an Underwriter in the event that such Underwriter (a) does not provide the Company, within a reasonable time, a certificate of tax residence within the meaning of the relevant Double Tax Treaty entered into with Spain duly issued by the tax authorities of its country of residence and dated not more than twelve months prior to the date on which the relevant amount is due and payable, or (b) operates through a tax haven jurisdiction (as defined in Royal Decree 1080/1991, of July 5, 1991, as amended).

(f) If an Underwriter determines, in its sole discretion, that it has received a refund of any Taxes as to which it has been paid additional amounts pursuant to Section 2(e), it shall pay to the Company an amount equal to such refund (but only to the extent of the additional amounts paid under Section 2(e) with respect to the Taxes giving rise to such refund), net of all out-of-pocket expenses (including Taxes) of such Underwriter and without interest (other than any interest paid by the relevant jurisdiction with respect to such refund). The Company, upon the request of such Underwriter, shall repay to such Underwriter the amount paid over pursuant to this paragraph (f) (plus any penalties, interest or other charges imposed by the relevant jurisdiction) in the event that such Underwriter is required to repay such refund to such jurisdiction. Notwithstanding anything to the contrary in this paragraph (f), in no event will the Underwriter be required to pay any amount to the Company pursuant to this paragraph (f) the payment of which would place the Underwriter in a less favorable net after-Tax position than the Underwriter would have been in if the Tax in respect of which additional amounts were paid and giving rise to such refund had not been deducted, withheld or otherwise imposed and the additional amounts paid with respect to such Tax had never been paid. This paragraph shall not be construed to require any Underwriter to make available its Tax returns (or any other information relating to its Taxes that it deems confidential) to the Company or any other person.

(g) In connection with the offering of the Offered Shares, [·] (or its agents) on behalf of itself and the other Underwriters (the “Stabilization Agent”) may, to the extent permitted by applicable laws and regulations, at its discretion, over-allot Class B Shares

(including in the form of ADSs), or effect transactions in any over-the-counter market or otherwise, with a view to supporting the market price of the Class B Shares (including in the form of ADSs), at a level higher than that which might otherwise prevail in the open market. Such transactions may commence on or after the date of commencement of trading of the Offered Shares on the Madrid and Barcelona Stock Exchanges and the ADSs on the Nasdaq Global Select Market and will end no later than 30 calendar days after the date of commencement of trading of the Offered Shares on the Madrid and Barcelona Stock Exchanges and the ADSs on the Nasdaq Global Select Market (the “Stabilization Period”). In so doing, the Stabilization Agent shall act as principal and not as agent for the Company and any loss resulting from stabilization shall be borne, and any profit arising therefrom shall be beneficially retained, by the Stabilization Agent on behalf of itself and the other Underwriters in the manner agreed between them. There is no assurance that such transactions will be undertaken and, if commenced, they may be discontinued at any time. There shall be no obligation on the Stabilization Agent to enter into such transactions . All such stabilization shall be conducted in accordance with applicable laws and regulations (including, when applicable, Commission Regulation (EC) No. 2273/2003). The Company authorizes the Stabilization Agent on behalf of itself and of the other Underwriters to make adequate public disclosure of the information required by Commission Regulation (EC) No. 2273/2003.

3. Delivery and Payment. (a) [·], as pre-funding banks (the “Pre-Funding Banks”), acting in their own name and on behalf of the other Underwriters in the proportion set out opposite their names in Schedule I, shall pay for the Underwritten Shares and the Option Shares (if the Over-allotment Option provided for in Section 2(b) hereof shall have been exercised on the date of this Underwriting Agreement) at the Purchase Price, without deduction of any commissions and expenses (the “Pre-funding Amount”), by 9:00 a.m. Madrid time (the “Pre-funding Time”) on the Madrid business day immediately following the date of this Underwriting Agreement (unless postponed in accordance with the provisions of Section 9 hereof) or on such other time not later than five Madrid business days after such date as shall be agreed upon by the Representatives and the Company (the “Closing Date”) on the terms and conditions and in the manner set forth in Appendix A hereto, which shall be deemed to form an integrated part of this Underwriting Agreement.

(b) If the Over-allotment Option provided for in Section 2(b) hereof is exercised after the date of this Underwriting Agreement, payment for the Option Shares shall be made to the Company in euro by wire transfer of immediately available funds to the Company Account (as such term is defined in Appendix A hereto) on the Option Closing Date. On the Option Closing Date, the Agent Bank (as such term is defined in Appendix A hereto) shall withdraw from, or segregate within, the Company Account sufficient funds (in the amount notified to it by the Representatives) to make payment, on the Option Closing Date, to the [Representatives, for the account of the several] Underwriters, of the aggregate commissions set forth in Section 2 of this Underwriting Agreement in connection with the Option Shares. Delivery of the Option Shares shall be made by the Company within 5 and 15 Madrid business days after the date of exercise of the Over-allotment Option and in the manner contemplated in the Stock Loan Agreement. If the Option Closing Date occurs after the Closing Date, the Company will deliver to the Representatives on the Option Closing Date, and the obligation of the Underwriters to purchase the Option Shares shall be conditioned upon receipt

of, supplemental opinions, certificates and letters confirming as of such date the opinions, certificates and letters delivered on the Closing Date pursuant to Section 6 hereof.

5. Agreements. The Company agrees with the several Underwriters that:

(a) Prior to the termination of the offering of the Offered Shares, the Company will not file any amendment of the Registration Statement or the ADR Registration Statement or supplement to the Prospectus or the Spanish Documents or any Rule 462(b) Registration Statement unless the Company has furnished you a copy for your review prior to filing and will not file any such proposed amendment or supplement to which you reasonably object.

(t) Prior to the Closing Date, the Company shall have furnished to the Representatives such further information, certificates and documents as the Representatives may reasonably request.

If any of the conditions specified in this Section 6 shall not have been fulfilled (or waived by the Representatives in the name and on behalf of the Underwriters) when and as provided in this Underwriting Agreement, or if any of the opinions and certificates mentioned above or elsewhere in this Underwriting Agreement shall not be reasonably satisfactory in form and substance to the Representatives and counsel for the Underwriters, this Underwriting Agreement and all obligations of the Underwriters hereunder may be terminated at, or at any time prior to, the Closing Date by the Representatives. Notice of such termination shall be given to the Company in writing or by telephone or facsimile confirmed in writing.

The documents required to be delivered by this Section 6 shall be delivered at the office of ▇▇▇▇▇ ▇▇▇▇ & ▇▇▇▇▇▇▇▇ LLP, counsel for the Underwriters, at ▇▇▇▇▇ ▇▇ ▇▇ ▇▇▇▇▇▇▇▇▇▇, ▇▇, ▇▇▇▇▇▇ ▇▇▇▇▇, ▇▇▇▇▇, on the Closing Date.

7. Reimbursement of Underwriters’ Expenses. If the sale of the Offered Shares provided for in this Underwriting Agreement is not consummated because any condition to the obligations of the Underwriters set forth in Section 6 hereof is not satisfied, because of any termination pursuant to Section 10 hereof or because of any refusal, inability or failure on the part of the Company to perform any agreement in this Underwriting Agreement or comply with any provision hereof other than by reason of a default by any of the Underwriters, the Company will reimburse the Underwriters severally through the Representatives on demand for all reasonable and documented expenses (including fees and disbursements of U.S., Spanish and Canadian counsel) that shall have been incurred by them in connection with the proposed purchase and sale of the Offered Shares.

8. Indemnification and Contribution. (a) The Company agrees to indemnify and hold harmless each Underwriter, the directors, officers, employees and agents of each Underwriter and each person who controls any Underwriter within the meaning of either the Act or the Exchange Act and each affiliate of any Underwriter within the meaning of the Act against any and all losses, claims, damages or liabilities, joint or several, to which they or any of them may become subject under the Act, the Exchange Act or other U.S. federal or state statutory law or regulation, at common law, under any non-U.S. law or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement as originally filed or in any amendment thereof, or in the ADR Registration Statement as originally filed or in any amendment thereof, or in any Preliminary Prospectus, the Disclosure Package, any Issuer Free Writing Prospectus or any Prospectus, or in any amendment thereof or supplement thereto, or any road show presentation of the Company, or in the Spanish Documents or any amendment or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and agrees to reimburse each such indemnified party, as incurred, for any legal or other expenses properly incurred by it in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that the Company will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon any such untrue statement or alleged untrue statement or omission or alleged omission made therein in reliance upon and in conformity with written information furnished to the Company by or on behalf of any Underwriter through the Representatives specifically for inclusion therein, it being understood and agreed that the only such information furnished by or on behalf of any Underwriter consists of the information described as such in Section 8(b). This indemnity agreement will be in addition to any liability which the Company may otherwise have.

(b) Each Underwriter severally and not jointly agrees to indemnify and hold harmless the Company, each of its directors, each of its officers who signs the Registration Statement, or the ADR Registration Statement, and each person who controls the Company within the meaning of either the Act or the Exchange Act, to the same extent as the foregoing indemnity from the Company to each Underwriter, but only with reference to written information

relating to such Underwriter furnished to the Company by or on behalf of such Underwriter through the Representatives specifically for inclusion in the documents referred to in the foregoing indemnity. This indemnity agreement will be in addition to any liability which any Underwriter may otherwise have. The Company acknowledges that [(i) the statements regarding delivery of the Offered Shares in the paragraph of the cover page and in the paragraph under the heading “Underwriting,” (ii) the list of Underwriters and their respective participation in the sale of the Offered Shares, (iii) the sentences related to concessions and reallowances in the paragraph under the heading “Underwriting” and (iv) the statements regarding stabilization in the paragraph under the heading “Underwriting” in each Preliminary Prospectus, the Disclosure Package and the Prospectus and the information contained in Section 6.5 of the Nota sobre las Acciones constitute the only information furnished in writing by or on behalf of the several Underwriters for inclusion in the Registration Statement, the ADR Registration Statement, each Preliminary Prospectus, the Prospectus, any Issuer Free Writing Prospectus or the Spanish Documents.

(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 this Section 8, notify the indemnifying party in writing of the commencement thereof; but the failure so to notify the indemnifying party (i) will not relieve it from liability under paragraph (a) or (b) above unless and to the extent it did not otherwise learn of such action and such failure results in the forfeiture by the indemnifying party of substantial rights and defenses and (ii) will not, in any event, relieve the indemnifying party from any obligations to any indemnified party other than the indemnification obligation provided in paragraph (a) or (b) above. The indemnifying party shall be entitled to appoint counsel of the indemnifying party’s choice at the indemnifying party’s expense to represent the indemnified party in any action for which indemnification is sought (in which case the indemnifying party shall not thereafter be responsible for the fees and expenses of any separate counsel retained by the indemnified party or parties except as set forth below); provided, however, that such counsel shall be satisfactory to the indemnified party. Notwithstanding the indemnifying party’s election to appoint counsel to represent the indemnified party in an action, the indemnified party shall have the right to employ separate counsel (including local counsel), and the indemnifying party shall bear the properly incurred fees, costs and expenses of such separate counsel if (i) the use of counsel chosen by the indemnifying party to represent the indemnified party would present such counsel with an actual or potential conflict of interest, (ii) the actual or potential defendants in, or targets of, any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that there may be legal defenses available to it and/or other indemnified parties which are different from or additional to those available to the indemnifying party, (iii) the indemnifying party shall not have employed counsel satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of the institution of such action, (iv) the indemnifying party shall authorize the indemnified party to employ separate counsel at the expense of the indemnifying party, (v) an Underwriter (in respect of a claim against it or any of its indemnified parties) gives notice to an indemnifying party that its insurers require it not to allow such participation or assumption of (or continued participation in or assumption of) the defense of the action or (vi) if in the reasonable judgment of an indemnified party its position and interests would be adversely affected by the indemnifying party’s participation in or assumption of (or continued participation in or assumption of) the

defense of such action. It is understood and agreed that the indemnifying party shall not, in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the fees and expenses of more than one separate firm (in addition to any local and/or regulatory counsel) for all indemnified parties, and that all such fees and expenses shall be paid or reimbursed as they are incurred. An indemnifying party will not, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent (i) includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding, and (ii) does not include any statement as to an admission of fault, culpability or failure to act by or on behalf of any indemnified party.

(d) In the event that the indemnity provided in paragraph (a), (b) or (c) of this Section 8 is unavailable to or insufficient to hold harmless an indemnified party for any reason, the Company and the Underwriters severally agree to contribute to the aggregate losses, claims, damages and liabilities (including legal or other expenses properly incurred in connection with investigating or defending the same) (collectively “Losses”) to which the Company and one or more of the Underwriters may be subject in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and by the Underwriters on the other from the offering of the Offered Shares; provided, however, that in no case shall any Underwriter (except as may be provided in any agreement among underwriters relating to the offering of the Offered Shares) be responsible for any amount in excess of the underwriting discount or commission applicable to the Offered Shares purchased by such Underwriter hereunder. If the allocation provided by the immediately preceding sentence is unavailable for any reason, the Company and the Underwriters severally shall contribute in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Company on the one hand and of the Underwriters on the other in connection with the statements or omissions which resulted in such Losses as well as any other relevant equitable considerations. Benefits received by the Company shall be deemed to be equal to the total net proceeds from the offering (before deducting expenses) received by it, and benefits received by the Underwriters shall be deemed to be equal to the total underwriting discounts and commissions, in each case as set forth on the cover page of the Prospectus. Relative fault shall be determined by reference to, among other things, whether any untrue or any alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information provided by the Company on the one hand or the Underwriters on the other, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The Company and the Underwriters agree that it would not be just and equitable if contribution were determined by pro rata allocation or any other method of allocation which does not take account of the equitable considerations referred to above. Notwithstanding the provisions of this paragraph (d), no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this Section 8, each person who controls an Underwriter within the meaning of either the Act or the Exchange Act and each director, officer, employee and agent of an Underwriter shall have the same rights to contribution as such Underwriter, and each person who controls the Company within the meaning of either the Act or

the Exchange Act, each officer of the Company who shall have signed the Registration Statement and the ADR Registration Statement and each director of the Company shall have the same rights to contribution as the Company, subject in each case to the applicable terms and conditions of this paragraph (d).

9. Default by an Underwriter. If any one or more Underwriters shall fail to purchase and pay for any of the Offered Shares agreed to be purchased by such Underwriter or Underwriters hereunder and such failure to purchase shall constitute a default in the performance of its or their obligations under this Underwriting Agreement, the remaining Underwriters shall be obligated severally to take up and pay for (in the respective proportions which the amount of Offered Shares set forth opposite their names in Schedule I hereto bears to the aggregate amount of Offered Shares set forth opposite the names of all the remaining Underwriters) the Offered Shares which the defaulting Underwriter or Underwriters agreed but failed to purchase; provided, however, that in the event that the aggregate amount of Offered Shares which the defaulting Underwriter or Underwriters agreed but failed to purchase shall exceed 10% of the aggregate amount of Offered Shares set forth in Schedule I hereto, the remaining Underwriters shall have the right to purchase all, but shall not be under any obligation to purchase any, of the Offered Shares and if such nondefaulting Underwriters do not purchase all the Offered Shares this Underwriting Agreement will terminate without liability to any nondefaulting Underwriter or the Company. In the event of a default by any Underwriter as set forth in this Section 9, the Closing Date shall be postponed for such period, not exceeding [five] Business Days, as the Representatives shall determine in order that any required changes in the Registration Statement, the ADR Registration Statement and the Prospectus or in any other documents or arrangements may be effected. Nothing contained in this Underwriting Agreement shall relieve any defaulting Underwriter of its liability, if any, to the Company and any nondefaulting Underwriter for damages occasioned by its default hereunder.

10. Termination.

(a) This Underwriting Agreement shall be subject to termination in the absolute discretion of the Representatives, by notice given to the Company prior to [·] [a.m./p.m.] on the Closing Date, if at any time prior to such time there shall have occurred any of the following: (i) since the time of execution of this Underwriting Agreement or the earlier respective dates as of which information is given in the Registration Statement, the ADR Registration Statement, the Preliminary Prospectus, the Prospectus and the Folleto (in each case, exclusive of any amendment or supplement thereto), there has been a material adverse change, or any development reasonably likely to result in a prospective material adverse change, in the business, properties, management, financial condition or results of operations of the Company and its subsidiaries, considered as a single business enterprise and whether or not arising in the ordinary course of business, the effect of which change or development is, in the judgment of the Representatives, so material and adverse as to make it impractical or inadvisable to proceed with the offering or the delivery of the Offered Shares on the terms and in the manner contemplated in each Preliminary Prospectus, the Disclosure Package, the Prospectus or the Folleto; (ii) a general banking moratorium has been declared by European Union, Spanish, United Kingdom, U.S. federal or New York State authorities or there is a material disruption in commercial banking or securities settlement, payment or clearance services in the European Union, Spain, the United Kingdom, the United States or New York State; (iii) there has occurred a suspension or material

limitation in trading in the Company’s Class A Shares or Class B Shares or securities generally on, or minimum or maximum prices shall have been established in, any of the Spanish Stock Exchanges, the London Stock Exchange, the New York Stock Exchange or the Nasdaq Global Select Market; or (iv) there has occurred (A) any change or any development involving a prospective change in the national or international financial, political or economic conditions, any financial markets or any currency exchange rates or controls, (B) an outbreak or escalation of hostilities or acts of terrorism or a declaration of a national emergency or war, or (C) any other calamity or crisis, if the effect of any such event specified in this Section 10(a)(iv), individually or together with any other such event, in the judgment of the Representatives, is so material and adverse as to make it impractical or inadvisable to proceed with the offering or the delivery of the Offered Shares on the terms and in the manner contemplated in the Preliminary Prospectus, the Prospectus or the Nota sobre las Acciones (exclusive of any amendment or supplement thereto).

(b) The Representatives may terminate this Underwriting Agreement, by notice to the Company, in the following circumstances: (i) any judicial or administrative authority suspends or revokes the offer of the Offered Shares prior to the Closing Time, (ii) any of the conditions set forth in Section 6 hereof shall not have been met by the Closing Date or (iii) admission to listing of the Offered Shares on any of the Barcelona or the Madrid Stock Exchanges shall not have been obtained by 23:59 pm (CET) on [the [third] Madrid business day immediately after the Settlement Date].

(c) In the event of termination of this Underwriting Agreement pursuant to this Section 10, all offers of the Offered Shares will be automatically terminated and all offers to purchase and all purchase orders related to the offering shall be cancelled, and the Company shall have no obligation to deliver the Offered Shares and the Underwriters or final purchasers, as the case may be, shall have no obligation to subscribe or purchase for the Offered Shares.

In the event that this Underwriting Agreement is terminated pursuant to this Section 10 after the subscription and payment by the Pre-Funding Banks for the Pre-Funded Shares (as such term is defined in Appendix A hereto), the Company undertakes (i) to purchase from the Pre-Funding Banks, the Underwriters or the final purchasers, as the case may be, for their redemption, within [two] Madrid business days from the date of termination of this Underwriting Agreement, the maximum number of Offered Shares permitted by law to be repurchased by the Company as treasury stock at the Purchase Price plus interest accrued thereon at an annual rate of [·]% from the date of this Underwriting Agreement by way of a reverse special stock transaction to be settled three Madrid business days after on a delivery versus payment basis through the facilities and in accordance with the procedures of Iberclear for the settlement of transactions in the Spanish Stock Exchanges, and (ii) to cause the Board of Directors of the Company to convene within the same term indicated above an Extraordinary General Meeting to approve a share capital reduction resolution, which capital reduction shall be completed within three months from the date of termination of this Underwriting Agreement, by way of repurchase by the Company of the remaining Offered Shares at the Purchase Price plus interest accrued thereon at an annual rate of [·]% from the date of this Underwriting Agreement for their redemption with simultaneous allocation of the capital redemption reserve provided for in article 335 of the Spanish Capital Companies Act out of distributable reserves such that the creditors of the

Company do not to have the right to oppose to such share capital reduction, in order to return the Purchase Price for the Offered Shares to the Pre-Funding Banks, to the Underwriters or to the final subscribers of the Offered Shares, as the case may be. Subject to approval of the foregoing share capital reduction by the Extraordinary General Meeting of the Company, the Company will purchase from the Pre-Funding Banks, the Underwriters or the final subscribers, as the case may be, any such Offered Shares not previously repurchased by it pursuant to the provisions of this paragraph.

(d) In the event of the purchase of the Offered Shares, the share capital reduction of the Company referred to in Section 10(c) above or any combination of the foregoing, the Agent Bank will, on the settlement date of the relevant special stock transaction, (x) pay the entire or the corresponding portion of the amount standing to the credit of the Company Account; and (y) if the entire amount standing to the credit of the Company Account is less than the sum of the aggregate Purchase Price, as the case may be, plus interest at an annual rate of [·]% from the date of this Underwriting Agreement, the Company hereby irrevocably undertakes to pay an amount equal to the difference, to the Underwriters and/or final purchasers of shares, as the case may be, in the case of each of (x) and (y) pro rata to the number of Offered Shares acquired by them and against redelivery of such Offered Shares to the Company.

11. Representations and Indemnities to Survive. The respective agreements, representations, warranties, indemnities and other statements of the Company or its officers and of the Underwriters set forth in or made pursuant to this Underwriting Agreement will remain in full force and effect, regardless of any investigation made by or on behalf of any Underwriter or the Company or any of the officers, directors, employees, agents or controlling persons referred to in Section 8 hereof, and will survive delivery of and payment for the Offered Shares.

The Company agrees that it will not claim that the Underwriters have rendered advisory services of any nature or respect, or owe an agency, fiduciary or similar duty to the Company, in connection with such transaction or the process leading thereto.

APPENDIX A

This Appendix A shall be deemed to form an integrated part of the Underwriting Agreement to which it is attached. All terms capitalized and not otherwise defined in this Appendix A shall have the meanings set forth in the Underwriting Agreement to which this Appendix A is attached.

The Underwriters hereby authorize the Pre-Funding Banks to subscribe and pay for the Underwritten Shares and the Option Shares (if the option provided for in Section 2 (b) hereof shall have been exercised on the date of the Underwriting Agreement) (the “Pre-Funded Shares”) and enter into, as the case may be, one or more loans on the terms the Pre-Funding Banks deem appropriate (in their sole discretion) to finance such subscription. The Pre-Funding Banks shall use their commercially reasonable efforts to obtain the financing of the amounts pre-funded by them on the most favorable terms reasonably available to them. Without prejudice to the other obligations of the parties under this Underwriting Agreement, the Underwriters shall, as against the Pre-Funding Banks, assume any liabilities arising from such subscription of the Pre-Funded Shares and any such loans in their respective underwriting proportions.

The payment contemplated by the preceding paragraph and representing an amount equal to the aggregate Purchase Price for the Pre-Funded Shares (the “Subscription Funds”) will be deposited by the Pre-Funding Banks with Banco Santander, S.A. (the “Agent Bank”) in the following account (the “Company Account”):

Upon subscription and payment for the Pre-Funded Shares, the Pre-Funding Banks, acting in their own name and on behalf of the other Underwriters, will be recorded temporarily as the owners of the Pre-Funded Shares, in the Company’s book entry registry held at Iberclear.

If an election has been made to have ADSs delivered and paid for hereunder in lieu of all or any portion of the Pre-Funded Shares, on the Closing Date, the Pre-Funding Banks, acting in their own name and on behalf of the other Underwriters, will transfer a portion of the Pre-Funded Shares corresponding to such ADSs to the Depositary in exchange for ADSs representing such Pre-Funded Shares.

The Company and the Underwriters hereby agree that at or prior to the Time of Delivery of ADSs, the Company shall transfer from the Company Account an amount in euro equivalent to the payment made pursuant to the preceding sentence, at an exchange rate of €1.00 = US$• (the noon buying rate on the date hereof), to the account of the Pre-Funding Banks that the Pre-Funding Banks shall have designated by notice to the Company given not less than 24 hours prior to the Time of Delivery of ADSs.

Unless otherwise agreed, all Pre-Funded Shares to be delivered on the Settlement Date shall be delivered to the final purchasers by book-entry transfer (transferencia contable de anotaciones en cuenta) to the account or accounts specified by the Underwriters at a participating entity in Iberclear in such respective portions as the Underwriters may designate not less than one full Madrid business day prior to the Closing Date. If an election has been made to acquire ADSs, the ADR certificates evidencing the Pre-Funded Shares shall be registered in such names and in such denominations as the Representatives may request not less than one full New York business day immediately preceding the Settlement Date.

It is understood and agreed by the parties hereto that no delivery of Pre-Funded Shares to be issued and subscribed or purchased under the Underwriting Agreement on the Closing Date or the Settlement Date, as the case may be, shall be effective until and unless payment therefor has been made pursuant to the Underwriting Agreement and the Company shall have furnished or caused to be furnished to the Pre-
