Ladies and Gentlemen:

Repsol YPF, S.A., a sociedad anónima organized under the laws of Spain (the “Selling Shareholder”) and the controlling shareholder of YPF Sociedad Anónima, a sociedad anónima organized under the laws of Argentina (the “Company”), proposes to sell to the international underwriters named in Schedule A attached hereto (the “Underwriters”), an aggregate of 26,215,000 Class D shares of common stock, Ps.10 par value per share, with one

vote per share and in book-entry form (the “Class D Shares”), of the Company, in the form of American Depositary Shares (“ADSs”), each representing the right to receive one Class D Share (the “Firm ADSs”). In addition, the Selling Shareholder proposes to grant to the Underwriters the option to purchase from the Selling Shareholder up to an additional 3,930,898 Class D Shares, in the form of ADSs (the “Additional ADSs”). The Firm ADSs and the Additional ADSs are hereinafter collectively sometimes referred to as the “Offering ADSs.” The Offering ADSs are described in the Prospectus which is referred to below.

The Offering ADSs have been issued in accordance with the Amended and Restated Deposit Agreement dated as of November 13, 2009 (the “Deposit Agreement”), among the Company, The Bank of New York Mellon, as depositary (in such capacity, the “Depositary”), and all owners and holders from time to time of American Depositary Receipts (“ADRs”) issued thereunder and evidencing ADSs.

The Company has prepared and filed, in accordance with the provisions of the U.S. Securities Act of 1933, as amended, and the rules and regulations thereunder (collectively, the “Securities Act”), with the U.S. Securities and Exchange Commission (the “SEC”) a registration statement on Form F-3 (File No. 333-170848) under the Securities Act, including a prospectus, relating to securities of the Company, including the Class D Shares, which registration statement incorporates by reference certain documents which the Company has filed, or will file, in accordance with the provisions of the U.S. Securities Exchange Act of 1934, as amended, and the rules and regulations thereunder (collectively, the “Exchange Act”).

Except where the context otherwise requires, “Registration Statement,” as used herein, means the registration statement, as amended at the time of such registration statement’s effectiveness for purposes of Section 11 of the Securities Act, as such section applies to the respective Underwriters (the “Effective Time”), including (i) all documents filed as a part thereof or incorporated or deemed to be incorporated by reference therein, (ii) any information contained or incorporated by reference in a prospectus filed with the SEC pursuant to Rule 424(b) under the Securities Act, to the extent such information is deemed, pursuant to Rule 430A or Rule 430C under the Securities Act, to be part of the registration statement at the Effective Time, and (iii) any registration statement filed to register the offer and sale of Class D Shares pursuant to Rule 462(b) under the Securities Act.

The Company has furnished to you, for use by the Underwriters and by dealers in connection with the offering of the Offering ADSs, copies of a preliminary prospectus supplement dated March 14, 2011, and the documents incorporated by reference therein, relating to the Offering ADSs. Except where the context otherwise requires, “Preliminary Prospectus,” as used herein, means such preliminary prospectus supplement, in the form so furnished, which includes the prospectus in the Registration Statement.

Except where the context otherwise requires, “Prospectus,” as used herein, means the prospectus, relating to the Offering ADSs, filed by the Company with the SEC pursuant to Rule 424(b) under the Securities Act on or before the second business day after the date hereof (or such earlier time as may be required under the Securities Act), or, if no such filing is required, the final prospectus included in the Registration Statement at the time it became

-2-

effective under the Securities Act, in each case in the form furnished by the Company to you for use by the Underwriters and by dealers in connection with the offering of the Offering ADSs.

“Permitted Free Writing Prospectuses,” as used herein, means the documents listed on Schedule B attached hereto and each “road show” (as defined in Rule 433 under the Securities Act), if any, related to the offering of the Offering ADSs contemplated hereby that is a “written communication” (as defined in Rule 405 under the Securities Act). The Underwriters have not offered or sold and will not offer or sell, without the Company’s consent, any Offering ADSs by means of any “free writing prospectus” (as defined in Rule 405 under the Securities Act) that is required to be filed by the Underwriters with the SEC pursuant to Rule 433 under the Securities Act, other than a Permitted Free Writing Prospectus.

“Disclosure Package,” as used herein, means the Preliminary Prospectus together with the Permitted Free Writing Prospectuses, if any, listed on Schedule B attached hereto.

Any reference herein to the Registration Statement, the Preliminary Prospectus, the Prospectus or any Permitted Free Writing Prospectus shall be deemed to refer to and include the documents, if any, incorporated by reference, or deemed to be incorporated by reference, therein (the “Incorporated Documents”), including, unless the context otherwise requires, the documents, if any, filed as exhibits to such Incorporated Documents. Any reference herein to the terms “amend,” “amendment” or “supplement” with respect to the Registration Statement, the Preliminary Prospectus, the Prospectus or any Permitted Free Writing Prospectus shall be deemed to refer to and include the filing of any document under the Exchange Act on or after the initial effective date of the Registration Statement, or the date of the Preliminary Prospectus, the Prospectus or such Permitted Free Writing Prospectus, as the case may be, and deemed to be incorporated therein by reference.

As used in this Agreement, “business day” shall mean a day on which the New York Stock Exchange (the “NYSE”) is open for trading. The terms “herein,” “hereof,” “hereto,” “hereunder,” “hereby,” “hereinafter” and similar terms, as used in this Agreement, shall in each case refer to this Agreement as a whole and not to any particular section, paragraph, sentence or other subdivision of this Agreement. The term “or,” as used herein, is not exclusive.

A registration statement on Form F-6 (File No. 33-63592), for the registration of the ADSs under the Securities Act, was filed with the SEC on June 17, 1993. The registration statement on Form F-6, as amended at the time it became effective (including by the filing of any post-effective amendments thereto, if applicable) is herein called the “ADS Registration Statement.”

The Company, the Selling Shareholder and the Underwriters agree as follows:

1. Sale and Purchase. Upon the basis of the representations and warranties and subject to the terms and conditions herein set forth, the Selling Shareholder agrees to sell to the respective Underwriters and each of the Underwriters, severally and not jointly, agrees to purchase from the Selling Shareholder, the number of Firm ADSs set forth opposite the name of such Underwriter in Schedule A, subject to adjustment in accordance with Section 11 hereof, in

-3-

each case at a purchase price of US$41.00 per ADS. A commission of 2.15% per ADS (the “Commission”) shall be deducted from such purchase price as set forth herein.

The Company and the Selling Shareholder are advised by you that the Underwriters intend (i) to make a public offering of their respective portions of the Firm ADSs as soon after the effective date of the Registration Statement as in your judgment is advisable and (ii) initially to offer the Firm ADSs, upon the terms set forth in the Prospectus. You may from time to time increase or decrease the public offering price after the initial public offering to such extent as you may determine.

In addition, the Selling Shareholder hereby grants to the several Underwriters the option (the “Additional ADSs Option”) to purchase, and upon the basis of the representations and warranties and subject to the terms and conditions herein set forth, the Underwriters shall have the right to purchase, severally and not jointly, from the Selling Shareholder, ratably in accordance with the number of Firm ADSs to be purchased by each of them, all or a portion of the Additional ADSs, at the same purchase price per ADS (less the same Commission) to be paid by the Underwriters to the Selling Shareholder for the Firm ADSs. The Additional ADSs Option may be exercised by the Underwriters at any time and from time to time on or before the thirtieth day following the date of the Prospectus, by written notice to the Selling Shareholder. Such notice shall set forth the aggregate number of Additional ADSs as to which the Additional ADSs Option is being exercised and the date and time when the Additional ADSs are to be delivered (any such date and time being herein referred to as an “additional time of purchase”); provided, however, that no additional time of purchase shall be earlier than the “time of purchase” (as defined below) nor earlier than the second business day after the date on which the Additional ADSs Option shall have been exercised nor later than the fifth business day after the date on which the Additional ADSs Option shall have been exercised. The number of Additional ADSs to be sold to each Underwriter shall be the number which bears the same proportion to the aggregate number of Additional ADSs being purchased as the number of Firm ADSs set forth opposite the name of such Underwriter on Schedule A hereto bears to the total number of Firm ADSs (subject, in each case, to such adjustment as the Underwriters may determine to eliminate fractional ADSs), subject to adjustment in accordance with Section 11 hereof.

2. Payment and Delivery. Payment of the purchase price less the Commission for the Firm ADSs shall be made to the Selling Shareholder by Federal Funds wire transfer against delivery of the Firm ADSs to you through the facilities of The Depository Trust Company (“DTC”) for the respective accounts of the Underwriters. Such payment and delivery shall be made at 10:00 A.M., New York City time, on March 28, 2011 (unless another time shall be agreed to by you, the Company and the Selling Shareholder or unless postponed in accordance with the provisions of Section 11 hereof). The time at which such payment and delivery are to be made is hereinafter sometimes called the “time of purchase.” Electronic transfer of the Firm ADSs, or the ADRs evidencing the Firm ADSs, shall be made to you at the time of purchase in such names and in such denominations as you shall specify.

Payment of the purchase price for the Additional ADSs (after deducting the Commission) shall be made at the additional time of purchase in the same manner and at the same office as the payment for the Firm ADSs. Electronic transfer of the Additional ADSs,

-4-

or the ADRs evidencing the Additional ADSs, shall be made to you at the additional time of purchase in such names and in such denominations as you shall specify.

Deliveries of the documents described in Section 9 hereof with respect to the purchase of the Firm ADSs and the Additional ADSs, if any, shall be made at the offices of Simpson Thacher & Bartlett LLP at 425 Lexington Avenue, New York, NY 10017, at 9:00 A.M., New York City time, on the date of the closing of the purchase of the Firm ADSs or the Additional ADSs, as the case may be.

Such Firm ADSs shall be taken up and paid for by such non-defaulting Underwriters in such amount or amounts as you may designate with the consent of each Underwriter so designated or, in the event no such designation is made, such ADSs shall be taken up and paid for by all non-defaulting Underwriters pro rata in proportion to the aggregate number of Firm ADSs set forth opposite the names of such non-defaulting Underwriters in Schedule A.

(b) In addition to the provisions of Sections 12(a) and (c), if (x) the Company fails, for whatever reason, to comply with its indemnity obligations set forth in Section 12(a) within a period of 45 days from the date the Company receives notice from any Underwriter of the occurrence of an event or circumstance that gives rise to indemnity pursuant to the provisions of Section 12(a) (or thereafter fails to so comply), or (y) a Bankruptcy Event occurs, then the Selling Shareholder agrees to indemnify, defend and hold harmless each Underwriter, its partners, directors and officers, and any person who controls any Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, and the successors and assigns of all of the foregoing persons, from and against any loss, damage, expense, liability or claim (including the reasonable cost of investigation) which, jointly or severally, any such Underwriter or any such person may incur under the Securities Act, the Exchange Act, the common law or otherwise, insofar as such loss, damage, expense, liability or claim arises out of or is based upon (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement (or in the Registration Statement as amended by any post-effective amendment thereof by the Company) or any omission or alleged omission to state a material fact required to be stated therein or necessary to make the statements therein not misleading, except insofar as any such loss, damage, expense, liability or claim arises out of or is based upon any untrue statement or alleged untrue statement of a material fact contained in, and in conformity with information furnished in writing by an Underwriter to the Company expressly for use in, the Registration Statement or arises out of or is based upon any omission or alleged omission to state a material fact in the Registration Statement in connection with such information, which material fact was not contained in such information and which material fact was required to be stated in such Registration Statement or was necessary to make such information not misleading, or (ii) any untrue statement or alleged untrue statement of a material fact included in any Prospectus or, when considered together with the Prospectus, in any Permitted Free Writing Prospectus or in any “issuer information” (as defined in Rule 433 under the Securities Act) of the Company, which “issuer information” is required to be, or is, filed with the SEC or any omission or alleged omission 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, except, with respect to such Prospectus or Permitted Free Writing Prospectus, insofar as any such loss, damage, expense, liability or claim arises out of or is based upon any untrue statement or alleged untrue statement of a material fact contained in, and in conformity with information furnished in writing by or on behalf of an Underwriter to the Company expressly for use in, such Prospectus or Permitted Free Writing Prospectus or any omission or alleged omission to state a material fact in such Prospectus or Permitted Free Writing Prospectus in connection with such information, which material fact was not contained in such information and which material fact was necessary in order to make the statements in any such information, in the light of the circumstances under which they were made, not misleading. Notwithstanding anything herein to the contrary, in no event shall the liability of the Selling Shareholder to provide indemnity pursuant to this Section 12(b) or Section 12(c) exceed an amount equal to the

-34-

proceeds received by the Selling Shareholder in respect of the sale of Offering ADSs pursuant to this Agreement, after deducting underwriting fees, but before deducting expenses. For the purposes of this Section 12(b), a “Bankruptcy Event” shall occur if the Company or any of its Subsidiaries (i) stops paying, or admits that it is generally unable to pay, its debts as they become due (excluding for such purposes the portion of any such debts as to which a reputable and creditworthy insurance company has acknowledged liability in writing); (ii) commences voluntarily proceedings under any applicable liquidation, insolvency, composition, reorganization or any other similar laws, or files an application for the appointment of an administrative or other receiver, manager or administrator, or any such or other similar official, in relation to the Company or any of its Subsidiaries; (iii) enters into any composition or other similar arrangement with such party’s creditors, or a proceeding is initiated against the Company or any of its Subsidiaries under applicable bankruptcy or insolvency law or law with similar effect and is not discharged or removed within 45 days; (iv) is adjudicated or found bankrupt or insolvent, or the Company or any of its Subsidiaries is ordered by a court or passes a resolution to dissolve, or a receiver, administrator or similar person is appointed in relation to, or a distress, execution, attachment, sequestration or other process is levied, enforced upon, sued out or put in force against, the undertakings or assets of the Company or any of its Subsidiaries and is not discharged, removed or stayed within 45 days; or (v) any event occurs or action is taken that has effects similar to those events or actions described herein.

(c) In addition to the provisions of Section 12(b), the Selling Shareholder agrees to indemnify, defend and hold harmless each Underwriter, its partners, directors and officers, and any person who controls any Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, and the successors and assigns of all of the foregoing persons, from and against any loss, damage, expense, liability or claim (including the reasonable cost of investigation) which, jointly or severally, any such Underwriter or any such person may incur under the Securities Act, the Exchange Act, the common law or otherwise, insofar as such loss, damage, expense, liability or claim arises out of or is based upon (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement (or in the Registration Statement as amended by any post-effective amendment thereof by the Company) or any omission or alleged omission to state a material fact required to be stated therein or necessary to make the statements therein not misleading, only to the extent that as any such loss, damage, expense, liability or claim arises out of or is based upon any untrue statement or alleged untrue statement of a material fact contained in, and in conformity with information furnished in writing by the Selling Shareholder to the Company expressly for use in, the Registration Statement or arises out of or is based upon any omission or alleged omission to state a material fact in the Registration Statement in connection with such information, which material fact was not contained in such information and which material fact was required to be stated in such Registration Statement or was necessary to make such information not misleading or (ii) any untrue statement or alleged untrue statement of a material fact included in any Prospectus or, when considered together with the Prospectus, in any Permitted Free Writing Prospectus or, in any “issuer information” (as defined in Rule 433 under the Securities Act) of the Company, which “issuer information” is required to be, or is, filed with the SEC, or any omission or alleged omission 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, only to the extent that, with respect to such Prospectus or Permitted Free Writing Prospectus, any such

-35-

loss, damage, expense, liability or claim arises out of or is based upon any untrue statement or alleged untrue statement of a material fact contained in, and in conformity with information furnished in writing by or on behalf of the Selling Shareholder to the Company expressly for use in, such Prospectus or Permitted Free Writing Prospectus or any omission or alleged omission to state a material fact in such Prospectus or Permitted Free Writing Prospectus in connection with such information, which material fact was not contained in such information and which material fact was necessary in order to make the statements in such information, in the light of the circumstances under which they were made, not misleading. Notwithstanding anything herein to the contrary, in no event shall the liability of the Selling Shareholder to provide indemnity pursuant to this Section 12(c), Section 12(b) or Section 12(f) exceed an amount equal to the proceeds received by the Selling Shareholder in respect of the sale of Offering ADSs pursuant to this Agreement, after deducting underwriting fees, but before deducting expenses.

(d) Each Underwriter severally agrees to indemnify, defend and hold harmless the Company, its directors and officers, the Selling Shareholder and any person who controls the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, and the successors and assigns of all of the foregoing persons, from and against any loss, damage, expense, liability or claim (including the reasonable cost of investigation) which, jointly or severally, the Company, the Selling Shareholder or any such person may incur under the Securities Act, the Exchange Act, the common law or otherwise, insofar as such loss, damage, expense, liability or claim arises out of or is based upon (i) any untrue statement or alleged untrue statement of a material fact contained in, and in conformity with information furnished in writing by such Underwriter to the Company expressly for use in, the Registration Statement (or in the Registration Statement as amended by any post-effective amendment thereof by the Company), or any omission or alleged omission to state a material fact in such Registration Statement in connection with such information, which material fact was not contained in such information and which material fact was required to be stated in such Registration Statement or was necessary to make such information not misleading; or (ii) any untrue statement or alleged untrue statement of a material fact contained in, and in conformity with information furnished in writing by such Underwriter to the Company expressly for use in, a Prospectus or a Permitted Free Writing Prospectus, or arises out of or is based upon any omission or alleged omission to state a material fact in such Prospectus or Permitted Free Writing Prospectus in connection with such information, which material fact was not contained in such information and which material fact was necessary in order to make the statements in such information, in the light of the circumstances under which they were made, not misleading; provided however, that the Underwriters shall not be liable for any losses, claims, damages or liabilities arising out of or based upon the Company or any Selling Shareholder’s failure to perform its obligations under Sections 5 and 6 of this Agreement, provided further, that the aggregate liability of each Underwriter under this clause (d) shall in no event exceed the net underwriting discounts and commissions received by such Underwriter under this offering;

(e) If any action, suit or proceeding (each, a “Proceeding”) is brought against a person (an “indemnified party”) in respect of which indemnity may be sought against the Company, the Selling Shareholder or an Underwriter (as applicable, the “indemnifying party”) pursuant to subsection (a), (b), (c) or (d), respectively, of this Section 12, such indemnified party shall promptly notify such indemnifying party in writing of the institution of such Proceeding

-36-

and such indemnifying party shall assume the defense of such Proceeding, including the employment of counsel reasonably satisfactory to such indemnified party and payment of all fees and expenses; provided, however, that the omission to so notify such indemnifying party shall not relieve such indemnifying party from any liability which such indemnifying party may have to any indemnified party (unless the indemnifying party has been materially prejudiced (including through the forfeiture of substantive rights or defenses) by such failure). The indemnified party or parties shall have the right to employ its or their own counsel in any such case, but the fees and expenses of such counsel shall be at the expense of such indemnified party or parties unless the employment of such counsel shall have been authorized in writing by the indemnifying party in connection with the defense of such Proceeding or the indemnifying party shall not have, within a reasonable period of time, employed counsel to defend such Proceeding or such indemnified party or parties shall have reasonably concluded, after consulting with counsel, that there are defenses available to it or them which are different from, additional to or in conflict with those available to such indemnifying party (in which case such indemnifying party shall not have the right to direct the defense of such Proceeding on behalf of the indemnified party or parties), in any of which events such reasonable fees and expenses shall be borne by such indemnifying party and paid as incurred (it being understood, however, that such indemnifying party shall not be liable for the expenses of more than one separate counsel (in addition to any one local counsel per jurisdiction) in any one Proceeding or series of related Proceedings representing the indemnified parties who are parties to such Proceeding). The indemnifying party shall not be liable for any settlement of any Proceeding effected without its written consent but, if settled with its written consent such indemnifying party agrees to indemnify and hold harmless the indemnified party or parties from and against any loss or liability by reason of such settlement. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by the second sentence of this Section 12(e), then the indemnifying party agrees that it shall be liable for any settlement of any Proceeding effected without its written consent if (i) such settlement is entered into more than 60 business days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party shall not have fully reimbursed the indemnified party in accordance with such request prior to the date of such settlement and (iii) such indemnified party shall have given the indemnifying party at least 30 days’ prior notice of its intention to settle. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened Proceeding 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 includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such Proceeding and does not include an admission of fault or culpability or a failure to act by or on behalf of such indemnified party.

(f) If the indemnification provided for in this Section 12 is unavailable to an indemnified party under subsections (a), (b), (c) and (d) of this Section 12 or insufficient to hold an indemnified party harmless in respect of any losses, damages, expenses, liabilities or claims referred to therein, then each applicable indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, damages, expenses, liabilities or claims (i) in such proportion as is appropriate to reflect the relative benefits received by the Company and the Selling Shareholder on the one hand and the Underwriters on the other hand

-37-

from the offering of the Offering ADSs 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 Selling Shareholder on the one hand and of the Underwriters on the other in connection with the statements or omissions which resulted in such losses, damages, expenses, liabilities or claims, as well as any other relevant equitable considerations. The relative benefits received by the Company and the Selling Shareholder on the one hand and the Underwriters on the other shall be deemed to be in the same respective proportions as the total proceeds from the offering (net of underwriting discounts and commissions but before deducting expenses) received by the Selling Shareholder, and the total underwriting discounts and commissions received by the Underwriters, bear to the aggregate public offering price of the Offering ADSs. The relative fault of the Company and the Selling Shareholder on the one hand and of the Underwriters on the other shall be determined by reference to, among other things, whether the untrue statement or alleged untrue statement of a material fact or omission or alleged omission relates to information supplied by the Company or the Selling Shareholder or by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The amount paid or payable by a party as a result of the losses, damages, expenses, liabilities and claims referred to in this subsection shall be deemed to include any legal or other fees or expenses reasonably incurred by such party in connection with investigating, preparing to defend or defending any Proceeding.

(g) The Company, the Selling Shareholder and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 12 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 in subsection (f) above. Notwithstanding the provisions of this Section 12, no Underwriter shall be required to contribute any amount in excess of the amount by which the total net underwriting discounts and commissions it received from the offering exceeds the amount of any damage which such Underwriter has otherwise been required to pay by reason of such untrue statement 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 to contribute pursuant to this Section 12 (g) are several in proportion to their respective underwriting commitments and not joint.

(h) The indemnity and contribution agreements contained in this Section 12 and the covenants, warranties and representations of the Company and the Selling Shareholder contained in this Agreement shall remain in full force and effect regardless of any investigation made by or on behalf of any Underwriter, its partners, directors or officers or any person (including each partner, officer or director of such person) who controls any Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, or by or on behalf of the Company or the Selling Shareholder, their respective directors or officers or any person who controls the Company or any Selling Shareholder within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, and shall survive any termination of this Agreement or delivery of the Offering ADSs to be sold by the Selling Shareholder pursuant hereto. The Company, the Selling Shareholder and each Underwriter agree promptly to notify

-38-

each other of the commencement of any Proceeding against it and, in the case of the Company or the Selling Shareholder, against any of their officers or directors in connection with the issuance and sale of Offering ADSs, or in connection with the Registration Statement, any Preliminary Prospectus, the Prospectus or any Permitted Free Writing Prospectus.

13. Information Furnished by the Underwriters and the Selling Shareholder. Each of the Company and the Selling Shareholder acknowledges and agrees that the statements with respect to the name of each Underwriter set forth in the Prospectus and the statements set forth in the fifth, eleventh and twelfth paragraphs under the caption “Underwriting” in the Prospectus, only insofar as such statements relate to the amount of selling concession and reallowance or to over-allotment and stabilization activities that may be undertaken by the Underwriters, constitute the only information furnished by or on behalf of the Underwriters for inclusion in the Registration Statement, the Preliminary Prospectus, the Prospectus or any Permitted Free Writing Prospectus, as such information is referred to in Sections 3 and 12 hereof. Each Underwriter acknowledges and agrees that the statements set forth in the Registration Statement, the Preliminary Prospectus and the Prospectus under the caption “Principal and Selling Shareholders,” only insofar as such statements relate to the Selling Shareholder, transactions entered into by the Selling Shareholder and the Selling Shareholder’s beneficial ownership of Class D Shares or securities of the Company, constitute the only information furnished by or on behalf of the Selling Shareholder for inclusion in the Registration Statement, the Preliminary Prospectus, the Prospectus or any Permitted Free Writing Prospectus, as such information is referred to in Sections 4 and 12 hereof.

14. Notices. Except as otherwise herein provided, all statements, requests, notices and agreements shall be in writing or by telegram or facsimile and, if to the Underwriters, shall be sufficient in all respects if delivered or sent to Credit Suisse Securities (USA) LLC, Eleven Madison Avenue, New York, NY 10010-3629, Attention: LCD-IBD, to Deutsche Bank Securities Inc. 60 Wall Street, 4th Floor, New York, NY 10005, Attention: ECM Syndicate Desk (F:212-797-9344) with a copy to the General Counsel (F:212-797-4564), to Goldman, Sachs & Co., : 200 West Street, New York, New York 10282, Attention: Registration Department (F:866-471-2526), to Itaú BBA USA Securities, Inc., 767 Fifth Avenue 50th Floor, New York, New York, 10153, Attention: Compliance — ECM Desk, to Morgan Stanley & Co.

15. Governing Law; Construction. This Agreement shall be governed by, and construed in accordance with, the laws of the State of New York. The section headings in this Agreement have been inserted as a matter of convenience of reference and are not a part of this Agreement.

16. Waiver of Immunity. This Agreement and any other documents delivered pursuant hereto or thereto, and any actions taken hereunder or thereunder, constitute commercial acts by the Company and the Selling Shareholder. Each of the Company and the Selling Shareholder irrevocably and unconditionally and to the fullest extent permitted by law, waives, and agrees not to plead or claim, any immunity from jurisdiction of any court or from any legal process (whether through service or notice, attachment prior to judgment, attachment in aid of execution, execution or otherwise) for itself of any of its property, assets or revenues wherever located with respect to its obligations, liabilities or any other matter under or arising out of or in connection with this Agreement and the Deposit Agreement and any document delivered pursuant hereto or thereunder, in each case for the benefit of each assigns, it being intended that, to the extent permitted by law, the foregoing waiver and agreement will be effective, irrevocable and not subject to withdrawal in any and all jurisdiction, and, without limiting the generality of the foregoing, agrees that the waivers set forth in this Section 16 shall have the fullest scope permitted under the U.S. Foreign Sovereign Immunities Act of 1976 and are intended to be irrevocable for the purposes of such act.

17. Submission to Jurisdiction. Except as set forth below, no claim arising out of or relating to this Agreement may be commenced, prosecuted or continued in any court other than the courts of the State of New York located in the City and County of New York or in the United States District Court for the Southern District of New York, which courts shall have exclusive jurisdiction over the adjudication of such claims, and the Company and the Selling Shareholder consent to the exclusive jurisdiction of such courts and personal service with respect thereto. The Company and the Selling Shareholder hereby consent to personal jurisdiction, service and venue in any court in which any claim arising out of or in any way relating to this Agreement is brought by any third party against any Underwriter or any indemnified party. Each Underwriter and the Company and the Selling Shareholder waive all right to trial by jury in any action, proceeding or counterclaim (whether based upon contract, tort or otherwise) in any way arising out of or relating to this Agreement. Each of the Company and the Selling Shareholder hereby appoints, without power of revocation, CT Corporation System as its agent (the “Authorized Agent”) to accept and acknowledge on its behalf service of any and all process which may be served in any action, proceeding or counterclaim in any way relating to or arising out of this Agreement. Each of the Company and the Selling Shareholder hereby represents and warrants that the Authorized Agent has accepted such appointment and has agreed to act as said agent for service of process, and each of the Company and the Selling Shareholder agrees to take any and all action, including the filing of any and all documents that may be necessary to continue such appointment in full force and effect as aforesaid. Service of process upon the Authorized Agent shall be deemed, in every respect, effective service of process upon the Company and the Selling Shareholder. Notwithstanding the foregoing, any action arising out of or based upon this Agreement may be instituted by any Underwriter, the partners, directors and officers of any Underwriter, or by any person who controls any Underwriter, in any court of competent jurisdiction in Argentina or Spain.

-40-

18. Judgment Currency. If for the purposes of obtaining judgment in any court is necessary to convert a sum due hereunder into any currency other than U.S. dollars, the parties hereto agree, to the fullest extent permitted by law, that the rate of exchange used shall be the rate at which in accordance with normal banking procedures the Underwriters could purchase U.S. dollars with such other currency in the City of New York on the banking business day preceding that on which final judgment is given. The obligation of the Company or the Selling Shareholder with respect to any sum due from them to any Underwriter or any person controlling any Underwriter shall, notwithstanding any judgment in a currency other than U.S. dollars, not be discharged until the first banking business day following receipt of such Underwriter or controlling person of any sum in such other currency, and only to the extent that such Underwriting or controlling person may in accordance with normal banking procedures purchase U.S. dollars with such other currency. If the U.S. dollars so purchased are less than the sum originally due to such Underwriter or controlling person hereunder, the Company and the Selling Shareholder agree as a separate obligation and notwithstanding any such judgment, to indemnify such Underwriter or controlling person hereunder, against such loss. If the U.S. dollars so purchased are greater than the sum originally due to such Underwriter or controlling person hereunder, such Underwriter or controlling person agrees to pay to the Company or the Selling Shareholder an amount equal to the excess of the U.S. dollars so purchased over the sum originally due to such Underwriter or controlling person hereunder.

19. Parties at Interest. The Agreement herein set forth has been and is made solely for the benefit of the Underwriters and the Company and the Selling Shareholder and to the extent provided in Section 12 hereof the controlling persons, partners, directors and officers referred to in such Section, and their respective successors, assigns, heirs, personal representatives and executors and administrators. No other person, partnership, association or corporation (including a purchaser, as such purchaser, from any of the Underwriters) shall acquire or have any right under or by virtue of this Agreement.

20. No Fiduciary Relationship. The Company and the Selling Shareholder hereby acknowledge that the Underwriters are acting solely as underwriters in connection with the purchase and sale of the Company’s securities. The Company and the Selling Shareholder further acknowledge that the Underwriters are acting pursuant to a contractual relationship created solely by this Agreement entered into on an arm’s length basis, and in no event do the parties intend that the Underwriters act or be responsible as a fiduciary to the Company or the Selling Shareholder, their respective management, stockholders or creditors or any other person in connection with any activity that the Underwriters may undertake or have undertaken in furtherance of the purchase and sale of the Company’s securities, either before or after the date hereof. The Underwriters hereby expressly disclaim any fiduciary or similar obligations to the Company or the Selling Shareholder, either in connection with the transactions contemplated by this Agreement or any matters leading up to such transactions, and the Company and the Selling Shareholder hereby confirm their understanding and agreement to that effect. The Company, the Selling Shareholder and the Underwriters agree that they are each responsible for making their own independent judgments with respect to any such transactions and that any opinions or views expressed by the Underwriters to the Company or the Selling Shareholder regarding such transactions, including, but not limited to, any opinions or views with respect to the price or

-41-

market for the Company’s securities, do not constitute advice or recommendations to the Company or the Selling Shareholder. The Company and the Selling Shareholder hereby waive and release, to the fullest extent permitted by law, any claims that the Company or the Selling Shareholder may have against the Underwriters with respect to any breach or alleged breach of any fiduciary or similar duty to the Company or the Selling Shareholder in connection with the transactions contemplated by this Agreement.

21. Counterparts. This Agreement may be signed by the parties in one or more counterparts which together shall constitute one and the same agreement among the parties.

22. Successors and Assigns. This Agreement shall be binding upon the Underwriters and the Company and the Selling Shareholder and their successors and assigns and any successor or assign of any substantial portion of the Company’s, the Selling Shareholder’s and any of the Underwriters’ respective businesses and/or assets.

23. Patriot Act. In accordance with the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)), the Underwriters are required to obtain, verify and record information that identifies their respective clients, including the Company, which information may include the name and address of their respective clients, as well as other information that will allow the Underwriters to properly identify their respective clients.

Capitalized terms not defined herein shall have the meaning given to them in the Underwriting Agreement

In order to induce you to enter into the Underwriting Agreement, the undersigned agrees that, for a period (the “Lock-Up Period”) of 90 days after the date of the final prospectus relating to the Offering, the undersigned will not, directly or indirectly (including through its subsidiaries), without the prior written consent of the Underwriters, (i) sell, offer to sell, contract or agree to sell, hypothecate, pledge, grant any option to purchase or otherwise dispose of or agree to dispose of, directly or indirectly, or file (or participate in the filing of) a registration statement with the SEC in respect of, or establish or increase a put equivalent position or liquidate or decrease a call equivalent position within the meaning of Section 16 of the Securities Exchange Act of 1934, as amended, and the rules and regulations of the SEC promulgated thereunder (the “Exchange Act”) with respect to, any shares of capital stock of the Company or ADSs representing those shares, or any securities convertible into or exercisable or exchangeable for shares of capital stock of the Company or ADSs representing those shares, or warrants or other rights to purchase shares of capital stock of the Company or ADSs representing those shares or any such securities, (ii) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of shares of capital stock of the Company or ADSs representing those shares, or any securities convertible into or exercisable or exchangeable for shares of capital stock of the Company or ADSs representing those shares, or warrants or other rights to purchase shares of capital stock of the Company or ADSs representing those shares or any such securities, whether any such transaction is to be settled by delivery of shares of capital stock of the Company or ADSs representing those shares or such other securities, in cash or otherwise, (iii) publicly announce an intention to effect any transaction specified in clause (i) or (ii) or (iv) vote in favor of any primary offerings of Class D Shares or ADS of the Company. The foregoing sentence shall not apply to (a) the registration of or sale to the Underwriters (as defined in the Underwriting Agreement) of any Class D Shares or ADSs pursuant to the Offering and the Underwriting Agreement, the sale of ADSs pursuant to the transactions described in the Preliminary Prospectus under the section “Recent Developments” or the sale of any of the remaining 13,781,031 Class D Shares or ADSs available for sale under the registration statement on form F-3 (File No. 333-170848), plus any Option ADSs not purchased by the Underwriters under the Underwriting Agreement at a price that is not lower than the Offering price, (b) the sale of Class D Shares to investors located in the Republic of Argentina representing in the aggregate no more than 2% (two percent) of the current outstanding capital stock of the Company, (c) the offer and sale of Class D Shares or ADSs to affiliates of Petersen Energía S.A. and Eton Park Master Fund, Ltd. and Eton Park Fund, L.P. pursuant to the options and warrants, respectively described in the Registration Statement, the Preliminary Prospectus and the Prospectus or (d) bona fide gifts or transfers to entities controlled

If (i) the Company notifies you in writing that it does not intend to proceed with the Offering, (ii) the registration statement filed with the SEC with respect to the Offering is withdrawn or (iii) for any reason the Underwriting Agreement shall be terminated prior to the “time of purchase” (as defined in the Underwriting Agreement), this Lock-Up Agreement shall be terminated and the undersigned shall be released from its obligations hereunder.

	Yours very truly,

Assuming that the Underwriting Agreement has been duly authorized, executed and delivered by the Company and the Selling Shareholder insofar as Republic of Argentina law and Kingdom of Spain law, respectively, is concerned, the Underwriting Agreement has been duly executed and delivered by the Company and the Selling Shareholder.

2. Assuming that the Amended and Restated Deposit Agreement dated as of November 13, 2009 (the “Deposit Agreement”), among the Company, The Bank of New York Mellon, as depositary (in such capacity, the “Depositary”), and all owners and holders from time to time of American Depositary Receipts (“ADRs”) issued thereunder and evidencing ADSs, has been duly authorized, executed and delivered by the Company insofar as Republic of Argentina law is concerned, the Deposit Agreement has been duly executed and delivered by the Company, and the Deposit Agreement is a valid and binding agreement of the Company, 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.

3. Upon payment for the Offering ADSs to be sold by the Selling Shareholder to each of the several Underwriters as provided in the Underwriting Agreement and the crediting of such ADSs on the records of The Depository Trust Company (“DTC”) to a security account or security accounts in the name of such Underwriter (assuming that such Underwriter does not have notice of any adverse claim (as such phrase is defined in Section 8-105 of the Uniform Commercial Code as in effect in the State of New York (the “UCC”)) to such ADSs or any security entitlement in respect thereof), (A) under Section 8-501 of the UCC, such Underwriter will acquire a security entitlement in respect of such ADSs and (B) to the extent governed by Article 8 of the UCC, no action based on any “adverse claim” (as defined in Section 8-102 of the UCC) to such ADSs may be asserted against such Underwriter; it being understood that for purposes of this opinion, we have assumed that when such payment, delivery and crediting occur, (x) such ADSs will have been registered in the name of Cede & Co. or such other nominee as may be designated by DTC, in each case on the Company’s share registry in accordance with its certificate of incorporation, bylaws and applicable law, (y) DTC will be registered as a “clearing corporation” within the meaning of Section 8-102 of the UCC and (z) appropriate entries to the securities account or accounts in the name of such Underwriter on the records of DTC will have been made pursuant to the UCC.

Assuming that the Underwriting Agreement has been duly authorized, executed and delivered by the Company and the Selling Shareholder insofar as Republic of Argentina law and Kingdom of Spain law are concerned, respectively, under the laws of the State of New York relating to personal jurisdiction, each of the Company and the Selling Shareholder has, pursuant to Section 17 of the Underwriting Agreement, validly and irrevocably submitted to the exclusive personal jurisdiction of any court of the State of New York located in the City and County of New York or in the United States District Court for the Southern District of New York (each a

B-1

“New York Court”) in any action arising out of or relating to the Underwriting Agreement or the transactions contemplated thereby, 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 the Authorized Agent as its authorized agent for the purpose described in Section 17 thereof; and service of process effected on such agent in the manner set forth in Section 17 thereof will be effective to confer valid personal jurisdiction on the Company and the Selling Shareholder, respectively. 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.

5. The Company is not, and after giving effect to the offering and sale of the Offering ADSs and the application of the proceeds thereof as described in the Prospectuses will not be, required to register as an “Investment Company,” as such term is defined in the Investment Company Act of 1940, as amended.

The execution and delivery by the Company of, and the performance by the Company of its obligations under, the Underwriting Agreement, the Deposit Agreement and the ADRs (collectively, the “Documents”) will not contravene any provision of 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 thereby, or any agreement, indenture, lease or other instrument to which the Company is a party or by which any of its properties is bound, that is identified on Schedule I hereto (which the Company has represented to us lists all material agreements governed by New York law to which the Company is a party or by which any of its properties is bound), provided that we express no opinion as to federal or state securities laws.

7. The execution and delivery by the Selling Shareholder of, and the performance by the Selling Shareholder of its obligations under, the Documents will not contravene any provision of 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 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 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.

9. 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

B-2

the execution, delivery and performance by the Selling Shareholder 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.

OPINION OF SEVERGNINI, ROBIOLA, GRINBERG & LARRECHEA

1. The Company has been duly organized and is validly existing as a corporation (sociedad anónima) under the laws of Argentina, with full corporate power and authority to own, lease and operate its properties and conduct its business as described in each of the Preliminary Prospectus Supplement and the Prospectus, to execute and deliver the Underwriting Agreement and the Deposit Agreement and to perform its obligations thereunder.

2. The Company is duly qualified to do business and is in good standing in each Argentine jurisdiction where the ownership or leasing of its properties or the conduct of its business requires such qualification, except where the failure to be so qualified and in good standing would not, individually or in the aggregate, have a Material Adverse Effect.

3. The Underwriting Agreement has been duly and validly authorized, executed and delivered by the Company. Assuming the Underwriting constitutes a legal, valid and binding agreement of the Company, enforceable against the Company in accordance with its terms under the laws of the State of New York, the Underwriting Agreement will constitute a legal, valid and binding agreement of the Company and enforceable against such parties in accordance with its terms.

4. The Deposit Agreement has been duly and validly authorized, executed and delivered by the Company and, assuming due authorization, execution and delivery of the Deposit Agreement by the Depositary, constitutes a valid and legally binding obligation of the Company, enforceable against the Company in accordance with its terms.

5. The Company has an authorized and outstanding capital stock as set forth in each of the Preliminary Prospectus Supplement and the Prospectus; all of the issued and outstanding shares of capital stock of the Company, including the Class D Shares, have been duly authorized and validly issued, are fully paid and non-assessable and, other than as set forth in each of the Preliminary Prospectus Supplement and the Prospectus, are free of statutory preemptive rights and accretion rights and, to our knowledge, contractual preemptive rights, accretion rights, resale rights, rights of first refusal and similar rights; and, other than as set forth in each of the Preliminary Prospectus Supplement and the Prospectus, the holders of the Offering ADSs will not be subject to personal liability by reason of being such holders; provided, however, that holders who have a conflict of interest with the Company and who do not abstain from voting or instructing the Depositary to vote at the respective shareholders’ meeting may be liable for damages to the Company, but only if the transaction would not have been approved without such holders’ votes. Furthermore, holders who willfully or negligently vote or instruct the Depositary to vote in favor of a resolution that is subsequently declared void by a court as contrary to the law or the Company’s bylaws may be held jointly and severally liable for damages to the Company or to other third parties, including other shareholders. To our knowledge, other than as set forth in each of the Preliminary Prospectus Supplement and the Prospectus, no options, warrants or other rights to purchase, agreements or other obligations to issue, or rights to convert

C-1

any obligations into or exchange any securities for, shares of capital stock of or ownership interests in the Company are outstanding.

6. No approval, authorization, consent or order of or filing with any Argentine federal, provincial or local governmental or regulatory commission, board, body, authority or agency, or of or with any Argentine self-regulatory organization or other non-governmental regulatory authority (including, without limitation, the BASE), or approval of the shareholders of the Company, is required in connection with the execution, delivery and performance by the Company and the Selling Shareholder of the Underwriting Agreement and the Deposit Agreement, the sale of the Offering ADSs or with the consummation by the Company and the Selling Shareholder of the other transactions contemplated by the Underwriting Agreement, and the Deposit Agreement, as the case may be.

7. The execution, delivery and performance by the Company of the Underwriting Agreement and the Deposit Agreement, and the consummation of the transactions contemplated by thereby, will not conflict with, result in any breach or violation of or constitute a default under (nor constitute any event which, with notice, lapse of time or both, would result in any breach or violation of, constitute a default under or give the holder of any indebtedness (or a person acting on such holder’s behalf) the right to require the repurchase, redemption or repayment of all or a part of such indebtedness under) (or result in the creation or imposition of a lien, charge or encumbrance on any property or assets of the Company) pursuant to (i) to our knowledge, upon due inquiry, any indenture, mortgage, deed of trust, bank loan or credit agreement or other evidence of indebtedness, or any license, lease, contract or other agreement or instrument, governed by the laws of Argentina, to which the Company is a party or by which it or any of its properties may be bound or affected, or (ii) to our knowledge, upon due inquiry, any decree, judgment or order of any Argentine federal, provincial or local court having jurisdiction over the Company or any of its properties, or, (iii) to our knowledge, upon due inquiry, any Argentine federal, provincial or local law, regulation or rule, (iv) to our knowledge, upon due inquiry, any rule or regulation of any Argentine self-regulatory organization or other non-governmental regulatory authority (including, without limitation, the rules and regulations of the BASE), or (v) the charter or bylaws (estatutos sociales) or equivalent constituent documents of the Company, except, in the case of each of clauses (i), (ii), (iii) and (iv), for each conflicts, breaches, defaults or violations as would not, individually or in the aggregate, have a Material Adverse Effect.

8. The Selling Shareholder has valid marketable title to the Class D Shares underlying the Offering ADSs to be sold by the Selling Shareholder pursuant to the Underwriting Agreement.

9. The execution, delivery and performance by the Selling Shareholder of the Underwriting Agreement, the sale of the Offering ADSs by the Selling Shareholder and the consummation by the Selling Shareholder of the transactions contemplated thereby do not and will not conflict with, result in any breach or violation of (i) any Argentine federal, provincial or

C-2

local law, regulation or rule, or (ii) any rule or regulation of any Argentine self-regulatory organization or other non-governmental regulatory authority (including, without limitation, the rules and regulations of the BASE) or, (iii) to our knowledge, upon due inquiry, any decree, judgment or order of any Argentine federal, provincial or local court having jurisdiction over the Selling Shareholder or any of its properties, except, in the case of each of (i), (ii) and (iii) for each conflicts, breaches or violations as would not, individually or in the aggregate, have a Material Adverse Effect on the ability of the Selling Shareholder to consummate the transaction contemplated under the Underwriting Agreement.

10. To our knowledge, after due inquiry, the Company is not in breach, violation of or in default under (nor has any event occurred which, with notice, lapse of time or both, would result in any breach or violation of, or constitute a default under or give the holder of any indebtedness (or a person acting on such holder’s behalf) the right to require the repurchase, redemption or repayment of all or a part of such indebtedness under) (i) the charter or bylaws (estatutos sociales) or equivalent documents of the Company, or (ii) any material indenture, mortgage, deed of trust, bank loan or credit agreement or other material evidence of indebtedness, or any license, lease, contract or other agreement or instrument, governed by the laws of Argentina, to which the Company is a party or by which any of its properties may be bound or affected, or (iii) any material Argentine federal, provincial or local law, regulation or rule, or (iv) any material rule or regulation of any Argentine self regulatory organization or other non-governmental regulatory authority (including, without limitation, the rules and regulations of the BASE) or (v) any material decree, judgment or order of any Argentine federal, provincial or local court having jurisdiction over the Company or any of its properties.

11. To our knowledge, after due inquiry (i) the Company is not a party to any legal or governmental action or proceeding that challenges the validity or enforceability, or seeks to enjoin the performance of the Underwriting Agreement or the Deposit Agreement; and (ii) except as disclosed in each of the Preliminary Prospectus Supplement and the Prospectus, there are no material actions, suits, claims, investigations or proceedings pending or threatened, to which the Company or the Selling Shareholder is or would be a party or to which any of their respective properties is or would be subject, before or by any Argentine federal, provincial or local governmental or regulatory commission, board, body, authority or agency.

12. The statements in each of the Registration Statement, the Preliminary Prospectus Supplement and the Prospectus under the headings “Business—Regulatory Framework and Relationship with the Argentine Government,” “Business—Environmental Matters—YPF Argentine Operations,” “Item 5. Update of Legal Proceedings—Argentina,” “Additional Information—Directors,” “Item 10. Additional Information—Capital Stock,” “Dividends,” “Material Tax Considerations—Argentine Tax Considerations” and “Enforcement of Judgments Against Foreign Persons,” insofar as such statements constitute summaries of documents governed by or issued pursuant to Argentine law or Argentine legal proceedings or refer to matters of Argentine law or legal conclusions under Argentine law, are accurate and complete in all material respects and present fairly the information purported to be shown.

13. To our knowledge, after due inquiry, except as disclosed in each of the Preliminary Prospectus Supplement and the Prospectus, the Company has all concessions, licenses, permits,

C-3

certificates and other approvals or authorizations from all governmental and regulatory officials and bodies of Argentina that are necessary to the conduct of its business in Argentina and to the ownership, lease or right to use of its properties, and is in compliance with the terms and conditions of the foregoing, except to the extent that the failure to have any such concessions, licenses, permits, certificates and other approvals or authorizations or to be in compliance therewith would not result, individually or in the aggregate, in a Material Adverse Effect.

14. The Company has good and marketable title to all material real property and good and marketable title to all material personal property owned, in each case free and clear of all liens, encumbrances and defects except, in each case, as described or referred to in each of the Preliminary Prospectus Supplement and the Prospectus or such as do not materially affect the value of such property and do not materially interfere with the use made and proposed to be made of such property by the Company; and any material real property and buildings held under lease by the Company are held by it under valid, existing and enforceable leases with such exceptions as are not material and do not interfere with the use made or proposed to be made of such property and buildings by the Company.

15. Payments of dividends or other disbursements to the shareholders by the Company are not subject to any restrictions under Argentine law other than those described in each of the Preliminary Prospectus Supplement and the Prospectus. All dividends and other distributions declared and payable on the Offering ADSs, in cash or in securities, may, under current Argentine law and regulations, including any foreign exchange or foreign currency approvals, be paid to the Depositary and to the holders of the ADSs, as the case may be, in Argentine pesos and may be converted freely into foreign currency that may be transferred out of Argentina in accordance with the Deposit Agreement, and all such dividends and other distributions made to holders of the Offering ADSs who are non-residents of Argentina currently are not subject to Argentine withholding or other taxes under Argentine laws and regulations and are otherwise currently free and clear of any other tax, duty, withholding or deduction in Argentina and do not require any governmental authorization in Argentina.

16. No stamp or other issuance or transfer taxes or duties and no capital gains, income, withholding or other taxes are payable by or on behalf of the Underwriters or the Depositary to Argentina or to any political subdivision or taxing authority thereof or therein in connection with the sale of the Class D Shares in accordance with the Underwriting Agreement, the deposit of the Class D Shares against issuance of ADRs evidencing the Offering ADSs in the manner contemplated in the Deposit Agreement, the sale and delivery by the Underwriters of the Offering ADSs, as the case may be, as contemplated in the Underwriting Agreement and the Prospectus, or the execution and delivery of the Underwriting Agreement or the Deposit Agreement.

17. The Class D Shares underlying the Offering ADSs are listed on the BASE and, to our knowledge, the Company has not received any notice of any proceedings relating to the delisting of the Class D Shares from such stock exchange.

18. The Underwriting Agreement and the Deposit Agreement do not contravene Argentine law or public policy.

C-4

19. The Company has the legal capacity to sue and be sued in its own name under the laws of Argentina; the submissions by the Company to the jurisdiction of the U.S. federal and state courts in the Borough of Manhattan in the City and County of New York and the United States District Court for the Southern District of New York set forth in the Underwriting Agreement constitute valid and legally binding obligations of the Company, and service of process effected in the manner set forth in the Underwriting Agreement, assuming validity under the laws of the State of New York, will be effective to confer valid personal jurisdiction over the Company under the laws of Argentina; and neither the Company nor its assets are entitled to immunity from suit, execution or other legal process in Argentina. But the service of process by the mailing of copies of such process to the Company’s domicile in Argentina may be considered null and void unless the Company acknowledges receipt of such service and, consequently, any judgment against the Company obtained pursuant to service of process in such manner would not be recognized nor would be enforceable in the Argentine courts. Service of process to the Company in Argentina may have to follow Argentine procedural rules.

20. The choice of laws of the State of New York as the governing law of the Underwriting Agreement and the Deposit Agreement is a valid choice of law under the laws of Argentina, and the Argentine courts will recognize the choice of laws of the State of New York as the governing law of the Underwriting Agreement and the Deposit Agreement.

21. Any judgment obtained in a U.S. federal or state court of competent jurisdiction sitting in New York City arising out of or in relation to the obligations of the Company or the Selling Shareholder under the Underwriting Agreement or the Deposit Agreement or the transactions contemplated thereby will be enforced against the Company or the Selling Shareholder, as applicable, and will be recognized in Argentina without reconsideration of the merits; provided that the requirements of Article 517 of the Argentine Civil and Commercial Procedure Code are met, as follows, (i) a final judgment was issued by a court competent in accordance with Argentine laws regarding conflict of laws and jurisdiction with either personal or in rem action with respect to personal property, as opposed to real property, which was transferred to Argentine territory during or after the prosecution of foreign action; (ii) the defendant against whom enforcement of the judgment is sought was personally served with a summons, and in accordance with due process of law, and was given an opportunity to defend against the action; (iii) the judgment must be valid in the jurisdiction where rendered and its authenticity must be established in accordance with the requirements of Argentine law; (iv) the judgment does not violate the principles of public policy of Argentine law; and (v) the judgment is not contrary to a prior or simultaneous judgment of an Argentine court if the plaintiff has also simultaneously sued in the Argentine courts; none of the provisions of the Underwriting Agreement (including, without limitation, the indemnification and contribution provisions set forth in Section 12 herein) or of the Deposit Agreement is or would be deemed against Argentine public policy; provided, that it is not clear whether under Argentine law an Argentine Court could or would permit the enforcement of a judgment against any of the Company’s property or assets located in Argentina to the extent that such property or assets have been or are determined by an Argentine Court to be used for the provision of an essential public service.

C-5

22. The Underwriting Agreement and the Deposit Agreement are in proper legal form for enforcement against the Company and the Selling Shareholder, as applicable, in Argentina. To ensure the legality, validity, enforceability or admissibility in evidence of the Underwriting Agreement or the Deposit Agreement in Argentina, it is not necessary that any of them or any other document related thereto be filed or recorded or enrolled in advance with any court or authority in Argentina or that any stamp, registration or similar tax be paid in Argentina, other than court costs, including filing fees and deposits to guarantee judgment required by Argentina law and regulations except that such agreements must be translated into Spanish by a sworn translator in Argentina.

23. We have participated in conferences with officers and other representatives of the Company and the Selling Shareholder, representatives of the independent public accountants of the Company and representatives of the Underwriters in the course of the preparation the Registration Statement, Preliminary Prospectus Supplement and the Prospectus, and also reviewed certain corporate and other records and documents furnished to us by the Company. Although we are not passing upon and do not assume responsibility for the accuracy, completeness or fairness of the statements contained in the Registration Statement, the Preliminary Prospectus Supplement or the Prospectus (except as and to the extent stated in paragraph 11 above), on the basis of the foregoing (A) nothing has come to our attention that causes us to believe that, (i) the Registration Statement, at the Effective Time, contained an 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, (ii) the Preliminary Prospectus Supplement, as of the Applicable Time (as defined below), when taken together with the Pricing Information (as defined below), contained an 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 (iii) the Prospectus as of the date of the Prospectus or as of the date hereof, contained or contains an untrue statement of a material fact or omitted or omits 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 (it being understood that we express no opinion in this paragraph 22 with respect to the financial statements and related schedules, and other financial and statistical data included or incorporated by reference therein). As used herein, (A) “Applicable Time” means [ ] [“A.M.” / “P.M.”], New York City time, on [ ], 2011 and (B) “Pricing Information” means (i) the number of ADSs offered for sale pursuant to the Prospectus and (ii) the public offering price per ADSs, as reflected on the cover page of the Prospectus.

24. In the event that for any reason (a) the preliminary injunction mentioned in (xii) above becomes applicable in whole or in part to the Selling Shareholder or (b) the decision mentioned in (xiii) above is revoked or ceases to be in effect in whole or in part, in each case after the sale of the Offering ADS by the Selling Shareholder pursuant to the Underwriting Agreement, such sale may not be unwound, declared null and void or rescinded, in whole or in part, and the plaintiffs, in case a final decision is awarded in the substantive claim, would only be entitled to obtain compensation or damages.

OPINION OF THE CORPORATE DIRECTOR OF LEGAL SERVICES
OF THE SELLING SHAREHOLDER

I am of the opinion that:

1. The Selling Shareholder has full corporate power, right and authority to execute and deliver the Underwriting Agreement, to sell and deliver the Offering ADSs and to perform its other obligations thereunder.

2. The Underwriting Agreement has been duly and validly authorized, executed and delivered by the Selling Shareholder.

3. The execution, delivery and performance by the Selling Shareholder of the Underwriting Agreement and the sale of the Offering ADSs,(a) do not violate the charter or bylaws (estatutos) of the Selling Shareholder, (b) will not breach or result in a default under any indenture, mortgage, deed of trust, loan agreement or other agreement or instrument to which the Selling Shareholder or any of its subsidiaries is a party or any of their properties may be bound or affected, except as would not, individually or in the aggregate, have a Material Adverse Effect, and (c) do not violate any Spanish statute or any rule or regulation that has been issued pursuant to any Spanish statute or any order known to us issued pursuant to any Spanish statute by any court or governmental agency or body having jurisdiction over the Selling Shareholder or any of its subsidiaries or any of their properties.

4. No consent, approval, authorization, order, registration or qualification of or with any Spanish governmental agency or body or, to our knowledge, any Spanish court is required for the execution, delivery and performance by the Selling Shareholder of the Underwriting Agreement, the sale of the Offering ADSs or the consummation of the other transactions contemplated thereby.

5. The choice of laws of the State of New York as the governing law of the Underwriting Agreement is a valid choice of law under the laws of the Kingdom of Spain, and the Spanish Courts will recognize the choice of the laws of the State of New York as the governing law of the Underwriting Agreement.

6. The indemnification and contribution provisions set forth in Section 12 of the Underwriting Agreement do not contravene Spanish law or public policy.

7. The Selling Shareholder has (i), pursuant to Section 17 of the Underwriting Agreement, validly and irrevocably submitted to the jurisdiction of the courts of the State of New York located in the City and County of New York and the United States District Court for the Southern District of New York, in any action or proceeding against it arising out of or relating to the Underwriting Agreement, (ii) validly and irrevocably waived any objection to the venue of a proceeding in any such court and (iii) validly and irrevocably appointed the authorized agent for service of process named in Section 17 of the Underwriting Agreement for the purposes

6. To my knowledge, after due inquiry, except as disclosed in each of the Preliminary Prospectus and the Prospectus, the Argentine Subsidiaries have all concessions, licenses, permits, certificates and other approvals or authorizations from all governmental and regulatory officials and bodies of Argentina that are necessary to the conduct of their respective business in Argentina and to the ownership, lease or right to use of their respective properties, and are in compliance with the terms and conditions of the foregoing, except to the extent that the failure to have any such concessions, licenses, permits, certificates and other approvals or authorizations or to be in compliance therewith would not result, individually or in the aggregate, in a Material Adverse Effect; and

7. (A) The Argentine Subsidiaries have good and marketable title to all property (real and personal) described in the Preliminary Prospectus and the Prospectus, if any, as being owned by any of them, free and clear of all liens, claims, security interests or other encumbrances; and (B) all the property described in the Preliminary Prospectus and the Prospectus, if any, as being held under lease by the Argentine Subsidiaries are held thereby under valid, existing and enforceable leases, except, in the case of each of (A) and (B), where the failure to do so would not, individually or in the aggregate, have a Material Adverse Effect.
