Comments

Interoil's total daily average operated production in April increased by 295
boepd compared with previous month. This increase is mainly coming from the
Argentinean fields whereas Colombia once again experienced a slight reduction of
flows.

In Argentina, the operated production increased by 319 boepd, as the gas
compressors have arrived allowing more gas flows especially from the Oceano
Field in the Santa Cruz assets. The reopening pulling program in the Santa Cruz
wells is still ongoing as programmed. In Mata Magallanes Oeste (MMO), the
monthly average production reached 30 bopd, a reduction from March figures due
to some producing wells waiting for the arrival of some spare parts.

In Colombia, production in Puli C had a modest increment of 3 boepd as the
result of the chemical treatment in some wells in Mana, Rio Opia and Ambrosia.
In the same line, the Vikingo production experienced a production reduction of
around 33 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.
