Hereby we inform as a Relevant Information Communication that, we share the comments made by the Executive President of GMP S.A., Mr. Francisco Dulanto, in a journalist report published today December 15, in “Gestión” newspaper.

After been awarded the license for 30 years for Blocks III and IV in Talara, Graña y Montero Petrolera (GMP) announced that it will begin operations in April 2015, and a production of 5,000 barrels per day is expected.
The drilling of a total of 560 development wells will demand an investment of US$ 560 million.
GMP will drill 23 wells per year in Block III, which is a higher number than the nine wells advised in the auction, and in Block IV it will explore 33 wells annually, which is superior to the five wells required.
GMP’s President, Francisco Dulanto, estimates that the production of both blocks will exceed 3,900 barrels per day, which are currently produced in average per day.
Petroperú will have at least 45 days to decide if it will participate in the license contracts of Blocks III and IV, with up to 25%.

Sincerely,
