Item 1
Buenos Aires, May 21, 2008


Messrs.
Buenos Aires Stock Exchange


 
Re.: Tender Offer by Petersen Energía Inversora S.A.


We hereby inform you that on May 20, 2008, at 8:40 p.m., YPF S.A. received a letter from Petersen Energía Inversora S.A. (“PEISA”), a company organized under the laws of the Kingdom of Spain; the letter includes the following relevant information:
 
 
§
On May 20, 2008, PEISA exercised an option to purchase from Repsol YPF S.A. and certain of its affiliates (“Repsol YPF Group”) shares representing 0.1% of the capital stock of YPF S.A., at a price of US$ 34.300013 per share.
 
 
§
Given the fact that as a result of the exercise of such option, if the purchase of the shares mentioned above is effected, PEISA and Petersen Energía S.A. (“PESA”), companies belonging to the Petersen Group, will become the owners of shares representing 15% of the capital stock of YPF S.A., the acquisition by PEISA constitutes an “Acquisition of Control” under the terms of Article 7, items (d), (e) and (f), and related provisions of the By-laws of YPF S.A.; therefore, PEISA has notified YPF S.A. that it will carry out a tender offer for all the outstanding shares of YPF S.A. at a price of US$ 49.45 (U.S. Dollars forty-nine with forty-five cents) per share, according to the terms of the letter and the copy of the notice attached thereto.
 
Please find attached to this instrument the letter received from PEISA and a copy of the notice related to the Tender Offer to be made by Petersen Energía Inversora S.A. in the relevant media.
 

Sincerely,

By YPF S.A.

City of Buenos Aires
At.: Chairman of the Board of Directors
Mr. Antonio Brufau Niubó

Dear Sirs,

We hereby address you in connection with Article 7 of the By-laws of YPF S.A. and in compliance with Article 3, paragraph b.1), Chapter XXVII, of the Rules of the Comisión Nacional de Valores.
 
In such respect, as you know, on February 21, 2008, Petersen Energía, S.A. ("PESA"), a company indirectly controlled by Messrs. Enrique and Sebastián Eskenazi, and Matías and Ezequiel Eskenazi Storey (the “Eskenazi Family) purchased shares representing 14.9% of the capital stock of YPF S.A.
 
On the other hand, today, Petersen Energía Inversora, S.A. (“PEISA”), a company also indirectly controlled by the Eskenazi Family, exercised the option to purchase shares representing 0.1% of the capital stock of YPF S.A. (the “Option Shares”) at a price of US$ 34.30013 per share.
 
By reason of the Option exercise by PEISA, the Eskenazi Family will become the indirect holder of shares representing 15% of the capital stock of YPF S.A. Therefore, the acquisition by PEISA of the Option Shares constitues an “Acquisition of Control” under the terms of Article 7, items (d) and (e) of the By-laws of YPF S.A.
 
Due to the foregoing, PEISA hereby announces and gives notice to YPF S.A., pursuant to the terms of Article 7, items (d), (e) and (f), and related provisions of the By-Laws of YPF S.A., of the “Acquisition of Control” mentioned in the preceding paragraphs and that it will carry out a tender offer for all the shares of YPF S.A. (the “Tender Offer”). Please note that only upon completion of the Tender Offer and once PEISA has acquired the shares to be offered for sale by the shareholders of YPF S.A. under the Tender Offer, shall the acquisition of Option Shares by PEISA be formalized (such acquisition is defined in Article 7, item (f)(i) of the By-laws of YPF as “PRELIMINARY AGREEMENT”).
 
Attached to this instrument you will find the text of the notice that will be published in the newspapers “Clarín” and “Ámbito Financiero”; that text will also be published in English in the “New York Post” according to the terms of the Tender offer.
 
We also inform the following:
 
(A) PEISA is a corporation (sociedad anónima) organized under the laws of the Kingdom of Spain; its corporate office is located at Velázquez 9, 1º Planta, 28006, Madrid, España (telephone: +34 915750008). Also, according to the terms of Article 123 of Law No. 19550, PEISA is registered with the Public Registry of Commerce of the City of Buenos Aires as from May 16, 2008, under Number 610, of Book 58, Volume B, of Foreign By-laws.

PETERSEN ENERGIA, S.A. ("Petersen SA") acquired 58,603,606 ADSs of YPF (representing 58,603,606 Class D Shares of YPF) representing 14.9% of the total outstanding capital stock of YPF pursuant to a stock purchase agreement between Repsol
 

 
YPF S.A. ("Repsol") and certain of its affiliates, dated as of February 21, 2008 (the "Acquisition").
