This press release may include "forward-looking statements" as defined in United States federal and Canadian securities laws. All statements, other than statements of historical facts, included in this press release that address activities, events or developments that InterOil expects, believes or anticipates will or may occur in the future are forward-looking statements, including in particular statements concerning drilling of the Antelope-2 well in the Elk/Antelope field and the characteristics of the Antelope reef structure. 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 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.
