UPDATE: Americas Petrogas and ExxonMobil Sign Agreement for Shale Oil and Gas Project in Argentina

Americas Petrogas announced that it has, through its wholly-owned Argentina subsidiary, Americas Petrogas Argentina S.A., entered into a farm-out agreement with ExxonMobil Exploration Argentina S.R.L., a wholly-owned subsidiary of Exxon Mobil Corporation

for the exploration and potential exploitation of Americas Petrogas's Los Toldos blocks (163,500 gross acres or 255 sections or 660 square kilometers) located in Neuquen, Argentina. The Los Toldos blocks are located in the western region of the Neuquen Basin and are in a favorable location relative to other recent discoveries of shale oil and shale gas in the Vaca Muerta formation. Barclay Hambrook, President and CEO of Americas Petrogas, stated "As the world's largest publicly-owned integrated oil and gas company, ExxonMobil brings vast experience, technology, research and financial resources to this joint venture with Americas Petrogas." Pursuant to the terms of the FOA, ExxonMobil has committed to fund US$53.9 million (including taxes) during the exploration phase with a further US$22.4 million (including taxes) if the parties proceed to the exploitation phase, for a total potential initial investment of US$76.3 million. This focus of exploration, exploitation and other related activities is expected to be directed towards the Los Toldos 1 and 2 blocks. ExxonMobil will earn a 45% interest in the Los Toldos blocks with Americas Petrogas retaining a 45% interest and the government entity, Gas y Petroleo del Neuquen ("G&P"), maintaining a 10% interest. ExxonMobil will also provide technical assistance on the Los Toldos blocks. The FOA is subject to approval by G&P. Americas Petrogas is the operator of the Los Toldos blocks and expects to spud the first well in the fourth quarter of 2011 with the primary target being the unconventional Vaca Muerta formation and potential secondary targets in other conventional and unconventional formations.
