Comments

Interoil's total daily average operated production in May decreased by 255 boepd
compared with previous month. This reduction is mainly coming from the
Argentinean fields whereas Colombia continues experiencing a slight reduction of
flows in lined with production forecast.

In Argentina, the operated production had 255 boepd reduction. The reopening
pulling program in the Santa Cruz wells is still ongoing as programmed. In Mata
Magallanes Oeste (MMO), the monthly average production reached 31 bopd.

In Colombia, production in Puli C decreased 3 boepd because of the natural
depletion experienced on the flowing wells in Mana, Rio Opia and Ambrosia
Fields. In the same line, the Vikingo production experienced a production
reduction of around 13 bopd as its downhole equipment might be experiencing an
accelerated worn-out due to its current working parameters.

The exploration campaign in Altair and LLA-47 blocks remains on hold pending
approval from local authorities. Conversations with the ANH concerning the
formal approval is still on hold waiting for the new authorities to take
position.
