      that, starting 21 months from closing, the investors will have the option
      to request redemption of portions of the original principal amount from

      InterOil's option, any cash payments contemplated under the debentures may
      be made in registered common shares issued at a ten percent discount to

interest from existing investors, the previously announced private placement was
increased from $40 million to $45 million. The securities will be issued with an
effective date of September 3, 2004. InterOil intends to use the net proceeds
for additional working capital and general corporate purposes.

commissioning phase, and provides incremental capital for InterOil's drilling
program and the securing of drilling rigs with improved capabilities" said Mr
Phil Mulacek, CEO of InterOil.

      The debentures mature on August 28, 2009 and bear interest at a rate of
8.875% per annum, payable quarterly. The debentures are convertible at the
investor's option at any time into common shares at a fixed conversion price of
US$20. 16 (C$26.45) per share. The definitive agreement provides that, starting
21 months from closing, the investors will have the option to request redemption
of portions of the original principal amount from InterOil in equal amounts at
stated dates until the maturity date. At InterOil's option, any cash payments
contemplated under the debentures may be made in registered common shares issued
at a ten percent discount to market.

      In addition, if after the one-year anniversary of closing, the trading
price exceeds US$28.23 (C$37.03) per share in certain circumstances. InterOil
may require the investors to convert the debentures into common shares at the
fixed conversion price.

      The debentures have certain customary covenants regarding, among other
things, the debt that InterOil may incur in an event of default under the
debentures, InterOil may be required to repay any outstanding amounts plus
accrued and unpaid interest, plus a 15% premium.

      In connection with the private placement, InterOil issued to the investors
five-year warrants to purchase 359,415 common shares at an exercise price equal
to US$21.91 (C$28.75).
