Buenos Aires, February 11, 2011.
 

Messrs.
National Securities Commission

 
 
Ref.: Information Article 2, Chapter XXI of the Rules – Supplementary Note

We notify the following:

The purpose of this letter is to comply with the requirements set forth under Article 2 of Chapter XXI of the Rules of the National Securities Commission.
 
Therefore, we attach the letter sent to the Buenos Aires Stock Exchange providing information in this respect.
 
 
 
Yours sincerely,

Buenos Aires, February 11, 2011.


Messrs.
Buenos Aires Stock Exchange

 
Attn. Mrs. Nora Ramos
 
Ref.: Information Article 2, Chapter XXI of the Rules — Providing additional information No. 00158538


We notify the following:

The purpose of this letter is to comply with the requirements.
 
Therefore, we hereby inform that the Company was informally notified today of the court decrees “Karcz, Miguel Angel and Other vs. REPSOL YPF S.A.- YPF S.A. - NATIONAL STATE (Ministry of Economy)- Declaration of Certainty” (File 2-K-2010), pursuant to which a preliminary injunction has been granted by the judge, ordering that those sales of shares of YPF S.A. and/or any other securities transactions that involve the sale, assignment or transfer of the shares of YPF. S.A. Argentine subsidiary, where the plaintiff and other beneficiaries of the employee share ownership plan (Programa de Propiedad Participada), organized under the Federation of Former Employees of YPF S.A., are not involved or are not a party thereto, be suspended.

We hereby inform you that the Company has filed an Appeal against such decision, justifying its request, and has requested that the injunction be suspended.  It should be noted that the decision referred to above is not final yet.

In addition, we have argued that the injunction should be revoked, among other reasons because such injunction seems excessive, implausible, inadmissible, and irrational, and does not bear any patrimonial proportion with the alleged right that it intended to protect, being this type of general measure excessive.  In addition, the claim brought by the plaintiff is barred by the statute of limitations and the plaintiff has previously declined to file a claim against YPF S.A and Repsol YPF S.A.

For the reasons explained above, we request to this Exchange that it immediately allows trading to resume.
 
 
 
Yours sincerely,
