Buenos Aires, January 31, 2014 – Petrobras Argentina S.A. (Buenos Aires: PESA, NYSE: PZE) informs that on this date it has signed a purchase and sale agreement with YPF S.A for the sale of its entire interest in the Puesto Hernández Joint Venture (UTE) agreement, in an amount of US$ 40,713,000.

Puesto Hernández area, located in the Province of Neuquén and extending to the Province of Mendoza, covers 147 km2 and has a current oil production of approximately 4,000 barrels per day in connection with PESA’s interest.
