Securities Class Action Lawsuit Filed Against YPF Sociedad Anonima; 
Shareholders With Large Losses Encouraged to Contact Holzer Holzer &
Fistel, LLC Regarding April 6, 2013 Lead Plaintiff Deadline 
ATLANTA, GA -- (Marketwire) -- 02/06/13 --  A class action lawsuit
has been filed on behalf of investors who purchased the American
Depositary Shares ("ADSs") of YPF Sociedad Anonima ("YPF" or the
"Company") (NYSE: YPF) pursuant or traceable to the Company's March
23, 2011 offering (the "Offering"). The lawsuit, which was filed in
the United States District Court for the Southern District of New
York, alleges YPF, certain of its officers and directors, and the
underwriters of the Offering violated the Securities Act of 1933 (the
"Securities Act").  
On or about November 26, 2010, YPF filed a Form F-3 Registration
Statement (the "Registration Statement") for the Offering with the
SEC. On or about March 23, 2011, the Prospectus with respect to the
Offering, which forms part of the Registration Statement, became
effective and more than 26.2 million shares of YPF ADSs were sold to
the public at $41 per share, thereby valuing the total size of the
Offering at more than $1 billion.  
According to the complaint, YPF's Registration Statement failed to
disclose and misrepresented the following adverse facts, among
others, which existed at the time of the Offering: (1) that the
Company faced a risk of nationalization by the Argentinean
government; (2) that the risk of nationalization had increased
because of the Company's failure to: (a) adequately produce oil and
gas within Argentina; and (b) reinvest a substantial portion of its
profits back into the Company and its operations; (3) that the
Company was in breach of its concession contracts with various
Argentinean provinces; and (4) that nationalization by the
Argentinean government would likely have a severe adverse effect on
shareholders and on the Company's market value.  
If you purchased YPF ADSs pursuant or traceable to the Company's
March 23, 2011 Offering and suffered a net loss on those purchases,
you have the legal right to petition the Court to be appointed a
"lead plaintiff." A lead plaintiff is a representative party that
acts on behalf of other class members in directing the litigation.
Any such request must satisfy certain criteria and be made no later
than April 6, 2013. Any member of the purported class may move the
Court to serve as lead plaintiff through counsel of their choice, or
may choose to do nothing and remain an absent class member.  
Investors who are interested in serving as lead plaintiff or who have
questions concerning their legal rights may contact Michael I.
