Item 1.  Security and Issuer

The Annual General Shareholders Meeting of Repsol YPF, S.A. held on May 31, 2012 resolved to change the name of the Company from Repsol YPF, S.A. to Repsol, S.A. (“Repsol”).

Repsol hereby amends and supplements its report on Schedule 13D, as last amended on May 17, 2012 (as heretofore amended and restated, the “Schedule 13D”), with respect to the Class D Shares, nominal value PS. 10 per share (the “Class D Shares”), of YPF Sociedad Anónima, an Argentine corporation (the “Issuer” or the “Company”).  The principal executive offices of the Issuer are located at Macacha Güemes 515, C1106BKK Ciudad Autónoma de Buenos Aires, Argentina.  Unless otherwise indicated, capitalized terms used in this Amendment No. 8 (the “Amendment”), but not defined herein, shall have the meaning assigned to such terms in the Schedule 13D.

Item 2.  Identity and Background

Item 2 of the Schedule 13D is hereby amended and supplemented by the following information:

Repsol is filing this Amendment to Schedule 13D to reflect changes to its effective beneficial ownership of Class D Shares.

As previously reported, on May 7, 2012 the Expropriation Law went into effect in Argentina. The Expropriation Law rendered Argentina, by operation of Argentine law, the beneficial owner of 51% of the Class D shares of the Company, owned by Repsol.

On May 10, 2012, Caja de Valores, S.A. (“Caja”), the Argentine Depositary of the Issuer’s Class D Shares, informed Repsol that at the request of the Argentine appointed Interventor of the Issuer, the Caja had acknowledged the rights conferred upon Argentina by the Expropriation Law over 155,930,165 Class D Shares owned directly and indirectly by Repsol duly registered on the books of Caja.

On May 23, 2012, The Bank of New York Mellon informed Repsol that pursuant to various communications received by The Bank of New York Mellon from the Issuer, it appears that the number of Class D Shares, in the form of American Depositary Receipts of the Issuer, eligible for voting and other purposes directly or indirectly by Repsol as of such date was 25,300,788, in effect depriving Repsol of its ability to direct the vote or disposition over 44,659,360 Class D Shares.

Repsol does not concede that the Expropriation Law, or any of the actions described above, is valid and enforceable and accordingly reserves all rights to dispute or challenge the validity and enforceability of the Expropriation Law or any action, document or instrument in connection thereunder, in any forum. Nothing discussed herein constitutes, or should be construed as constituting, a waiver or otherwise of any rights, actions or other relief available to Repsol in connection with the foregoing.

As previously reported, Repsol, in its capacity as lender, entered into (i) a Seller Credit Agreement dated February 21, 2008 with Petersen Energía S.A. (“Petersen Energía”), as borrower, and The Bank of New York, as Collateral Agent (The “First Seller Credit Agreement”) and (ii) a Seller Credit Agreement dated May 19, 2011 with Petersen Energía Inversora S.A.U. (“PEISA”), as borrower and The Bank of New York Mellon, as Collateral Agent (the “Second Seller Credit Agreement” and together with the First Seller Credit Agreement, the “Seller Credit Agreements”), in order to finance in part the acquisition of certain Class D Shares by each of the Borrowers and their respective affiliates. Petersen Energía and PEISA are referred to herein as the “Borrowers.”

Pursuant to the terms of each Seller Credit Agreement, on May 30, 2012, Repsol notified (each an “Event of Default Notification”) the respective Borrower thereunder that certain Events of Default (as defined in the applicable Seller Credit Agreement) had occurred and were continuing to occur, and as a result, the Loans (as defined in each Seller Credit Agreement) became due and payable immediately, together with accrued interest thereon and all fees and other obligations of each Borrower accrued under the applicable Seller Credit Agreement.

The First Seller Credit Agreement is secured by Collateral (as defined in the First Pledge and Security Agreement), including certain Class D Shares, pursuant to the Pledge and Security Agreement dated February 21, 2008 between Petersen Energía, as pledgor and The Bank of New York, as collateral agent (the “First Pledge and Security Agreement”).

Page 3

The Second Seller Credit Agreement is secured by Collateral (as defined in the Second Pledge and Security Agreement), including certain Class D Shares, pursuant to the Pledge and Security Agreement dated May 19, 2011 between PEISA, as pledgor and The Bank of New York Mellon, as collateral agent (the “Second Pledge and Security Agreement” and together with the First Pledge and Security Agreement, the “Pledge Agreements”).

On May 30, 2012, Repsol requested and received a confirmation from each Borrower (each such confirmation, a “Voting Confirmation”) that (i) pursuant to Section 4.04(b) of the applicable Pledge Agreement, such Borrower ceased to be entitled to exercise the voting, consensual and other powers of ownership pertaining to the Pledged Shares (as defined in each Pledge Agreement) as of the occurrence of the Events of Default (as defined in the applicable Seller Credit Agreement); and (ii) pursuant to Section 4.05(a) of the applicable Pledge Agreement, the Collateral Agent thereunder has the right to exercise the voting, consensual and other powers of ownership pertaining to the Pledged Shares (as defined in the applicable Pledge Agreement) pursuant to instructions provided by Repsol.

In connection with the First Seller Credit Agreement and the Senior Secured Term Loan Facility (as defined in the First Intercreditor Agreement), Repsol entered into an Intercreditor Agreement, dated February 21, 2008, with certain lenders, Petersen Energía, as borrower, Credit Suisse, London Branch, as senior agent and intercreditor agent, Petersen Energía PTY, Ltd., and HSBC Bank plc, as collateral agent (the “First Intercreditor Agreement”). Repsol also entered into an Intercreditor Agreement dated May 9, 2011 with certain lenders, Petersen Energía Inversora, S.A.U., as borrower, Credit Suisse AG, London Branch, as senior agent and intercreditor agent, and The Bank of New York Mellon as Collateral Agent and Petersen Energía Inversora Holdings, S.A. as shareholder (the “Second Intercreditor Agreement,” and together with the First Intercreditor Agreement, the “Intercreditor Agreements”) relating to the Senior Secured Term Loan Facility (as defined in the Second Intercreditor Agreement) and the Second Seller Credit Agreement.

As a result of the events described above, and pursuant to the terms of each Seller Credit Agreement, each Pledge Agreement and the confirmations included in each Voting Confirmation, and subject to the provisions of the applicable Intercreditor Agreements, Repsol currently has the sole power to direct the vote and direct the disposition of 21,174,920 Class D Shares, in addition to the 25,300,788 Class D Shares described above.

The foregoing descriptions of each Seller Credit Agreement, each Event of Default Notification, each Pledge Agreement, each Voting Confirmation and each Intercreditor Agreement does not purport to be complete and is subject to, and qualified in its entirety by, the full text of each Seller Credit Agreement, each Event of Default Notification, each Pledge Agreement, each Voting Confirmation and each Intercreditor Agreement, as applicable which are incorporated by reference herein from Exhibits 7.06, 7.12 and 99.23 that were previously filed, and Exhibits 99.25-99.29 hereto.

The name, business address, present principal occupation or employment and citizenship of each director and executive officer of Repsol is set forth on Schedule A attached hereto.

During the last five years, none of Repsol and, to the best of Repsol’s knowledge, the persons listed on Schedule A attached hereto, has been convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors) or has been a party to a civil proceeding of a judicial or administrative body of competent jurisdiction and as a result of such proceeding was or is subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject, to federal or state securities laws or finding any violation with respect to such laws.

Except as set forth herein, Repsol does not have any plans or proposals that relate to or would result in any of the transactions described in subparagraphs (a) through (j) of Item 4 of Schedule 13D.

Repsol intends to use its Class D Shares to, from time to time, nominate and vote for certain directors and their alternates. In addition, Repsol reserves all rights to dispute and challenge the validity and enforceability of the Expropriation Law or any action, document or instrument in connection thereunder, in any forum.

Item 5.  Interest in Securities of the Issuer

Item 5(a) of the Schedule 13D is hereby amended and supplemented by the following information:

Subject to the events described under Item 2 above, Repsol beneficially owns, for the purpose of Rule 13d-3 promulgated under the Exchange Act, 46,475,858 Class D Shares, representing approximately 11.82% of the Issuer’s outstanding Class D Shares.

Except as set forth herein, none of Repsol, and, to the best of its knowledge, any persons named in Schedule A hereto owns beneficially any shares of the Issuer.

As described under Item 2 above, Repsol has sole power to direct the vote and to direct the disposition of 46,475,858 Class D Shares.

Item 5(c) of the Schedule 13D is hereby amended and supplemented by the following information:

Other than the events described in Item 2 of this Amendment, the transactions in the Class D Shares of the Issuer effected by Repsol or, to the knowledge of Repsol, any person named in Schedule A, since the filing of Repsol’s Amendment No. 7 to the Schedule 13D with the Securities and Exchange Commission on May 17, 2012 are listed in Schedule B.

Item 6. Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer

Item 6 of the Schedule 13D is hereby amended and supplemented by paragraphs three to fourteen under Item 2 above.

On November 12, 2008, Repsol entered into a Pledge and Security Agreement between PEISA, as pledgor, Repsol, as guarantor and The Bank of New York Mellon, as collateral agent (the “Santander Loan Pledge Agreement”), under which PEISA pledged Collateral (as defined in the Santander Loan Pledge Agreement) as security for the Secured Obligations (as defined in the Santander Loan Pledge Agreement). Such Collateral includes 2,210,192 Class D Shares. The Santander Loan Pledge Agreement contains other customary terms and conditions.

The Santander Loan Pledge Agreement was entered into in connection with a Guaranty Agreement dated June 6, 2008 between PEISA, as debtor, Repsol, as guarantor and Banco Santander, S.A. as financing entity (the “Santander Loan Guaranty”), whereby Repsol guaranteed the payment obligations incurred by PEISA under the U.S.$198,500,000 Credit Facility Agreement dated June 6, 2008 between PEISA, as borrower and Banco Santander, S.A., as financial entity (the “Santander Loan Agreement”), the proceeds of which were used to finance the acquisition of certain Class D Shares by PEISA and its affiliates.

Under the Santander Loan Agreement, principal payments are required to be made at certain periodic intervals up to November 15, 2013, the final maturity date. At such date, 82.25% of the principal is due and all other payments which PEISA is liable for must have been repaid. The loan bears an interest rate per annum as determined pursuant to a formula described in the Santander Loan Agreement. Upon the occurrence and during the continuance of a payment default, an additional interest rate of 2% per annum applies above the interest rate ordinarily payable. The Santander Loan Agreement and the Santander Loan Guaranty include other customary terms and conditions.

Page 5

On May 18, 2012, Banco Santander, S.A. sent a notice of default to PEISA, stating a partial default under the Santander Loan Agreement had occurred resulting from the failure of the Borrower to repay the May 15, 2012 installment, however it did not accelerate the obligations of PEISA under the Santander Loan Agreement. Banco Santander, S.A. claimed such payment from Repsol, in its capacity as guarantor of PEISA’s obligations under the Santander Loan Agreement. Repsol is considering its rights under the Santander Loan Pledge Agreement.

The foregoing descriptions of the Santander Loan Pledge Agreement, Santander Loan Guaranty and Santander Loan Agreement does not purport to be complete and is subject to, and qualified in its entirety by, the full text of the Santander Loan Pledge Agreement, Santander Loan Guaranty and Santander Loan Agreement, as applicable which are incorporated by reference herein from Exhibits 99.30, 99.31 and 99.32 hereto.
