Stephen Foss, Senior Independent non-executive Director and Chairman of the Remuneration Committee said:

"Today's grant of options is within the Company's LTIP scheme that was adopted in 2011. In designing the scheme, the Company, with the help of external consultants, carefully examined performance and undertook a benchmarking exercise.

"The Remuneration Committee has set very specific and challenging targets which, if met, will align management with shareholder interests. The delivery of the cross border pipeline is, in particular, of strategic importance to Amerisur and the Putumayo region as a whole."
