Note to Editors:

Andes is a Latin American energy group, with oil and gas, electricity distribution and hydro-electric power interests in Argentina. The Company's focus is on the Argentinean energy sector, which it believes offers premium assets at undervalued prices.

Fitch, an international ratings agency, has developed a methodology for rating stock risk and defines six categories of risk from Level 1 (least risk) to Level 5 (highest risk) and Level 6 attributable to those shares where there is insufficient information to quantify the risk.
