The logged interval defined above is only the upper section of the reservoir. The drilling has stopped here, above the zone in which oil was sampled in the Antelope-1 well, to obtain these intermediate logs and to flow test the gas portion of the reservoir before running casing. Casing off the upper gas interval will allow us to better evaluate the lower section of the reservoir where we will be testing for a potentially higher condensate-to-gas ratio at the base of the gas column. Due to the washouts observed on the logs throughout the wellbore, InterOil has determined that the packer required for a drill stem test is not likely to seal and would not provide definitive results on the condensate ratio. The forward program for the well is to perform a production test, run a 7 inch liner and tie back, then drill out to test and core the lower gas interval and potential oil leg section of the reservoir. The well will be drilled to approximately 8,285 feet (2,525) meters which is 1,056 feet (322 meters) deeper than the depth logged to date.

"These results continue to surpass our expectations as the logs of the Antelope-2 well are as good, or better than what we observed in our Antelope-1 well. These results combined with the reservoir coming in high, a larger dolomite section deeper in the reservoir and an increase in average porosity are encouraging." said Mr. Phil Mulacek, Chief Executive Officer.

These statements are based on certain assumptions made by the Company based on its experience and perception of current conditions, expected future developments and other factors it believes are appropriate in the circumstances. No assurances can be given however, that these events will occur. Actual results will differ, and the difference may be material and adverse to the Company and its shareholders. Such statements are subject to a number of assumptions, risks and uncertainties, many of which are beyond the control of the Company, which may cause our actual results to differ materially from those implied or expressed by the forward-looking statements.

In particular, there is no established market for natural gas in Papua New Guinea and no guarantee that oil, gas or condensate from the Elk/Antelope field will ultimately be able to be extracted and sold commercially. There is no guarantee that an oil leg will be established of a size and grade as to be commercially exploitable. In addition, there is no guarantee that the Antelope-2 well will be able to be drilled and/or tested in the manner proposed, nor that it will ultimately be successful.

Investors are urged to consider closely the disclosure in the Company's Form 40-F, available from us at www.interoil.com or from the SEC at www.sec.gov and its and its Annual Information Form available on SEDAR at www.sedar.com.
