SINTANA ENERGY INC. ANNOUNCES VMM-37 RESOLUTION

Sintana Energy Inc.'s subsidiaries, Patriot Energy Oil and Gas Inc. and Patriot Energy Sucursal Colombia, have reached agreement to resolve the previously announced arbitration against ExxonMobil Exploration Colombia Ltd. and ExxonMobil Exploration Colombia Ltd. Sucursal Colombia associated with the VMM-37 block located in Colombia's Middle Magdalena Valley basin.

Pursuant to such resolution: Patriot and ExxonMobil have agreed to dismiss the current arbitration. Patriot has agreed to conditionally assign all of its rights and interests associated with VMM-37 to ExxonMobil, and ExxonMobil has agreed to make two cash payments to Patriot, the first $3-million due within 60 days of execution and a second payment of $6-million, together with mutual releases, conditioned on approval of the assignment by the appropriate Colombian governmental agencies, including the Agencia Nacional de Hidrocarburos and other contractual requirements.

Robert Bose, chief executive officer of Sintana, commented: "We are pleased to bring this matter associated with our legacy position in Colombia to an initial conclusion. This outcome supports our efforts to streamline operations focusing resources on our active, high-impact portfolio across the Atlantic margin."
