Forward-Looking Statements

This news release includes forward-looking statements within the meaning of the U.S. federal and Canadian securities laws. Any such statements reflect Bontan's current views and assumptions about future events and financial performance. Bontan cannot assure that future events or performance will occur. Important risks and factors that could cause actual results or events to differ materially from those indicated in our forward-looking statements, include, but are not limited to: the effect of economic and political developments in Israel and in the Mideast; the reliance on the working interest owners, as well as third-party consultants and contractors, to develop the Offshore Israel Project; the ability of IPC Cayman to raise sufficient capital to demonstrate to the Israeli Ministry of Natural Infrastructures adequate financial capability and to satisfy its obligations for the costs of drilling and development; the risk that the final interpretation of the seismic and other data may show or suggest, or that drilling may ultimately demonstrate, that either or both of the Licenses contain no, or non-commercial amounts of, hydrocarbons; the volatility in commodity prices for crude oil and natural gas; the presence or recoverability of estimated reserves; the potential unreliability or other effects of geological and geophysical analysis and interpretation; exploration and development, drilling and operating risks; competition for development of the Offshore Israel Project; environmental risks; government regulation or other action, including the potential change in tax and royalty provisions under active consideration by the Israeli government; potential disruption from terrorist activities or warfare in the region or at the Offshore Israel Project site; general economic conditions; limited market available in Israel for oil and gas that may be found in commercial quantities; other risks generally associated with the exploration and development of international offshore drilling projects in several thousand feet of water; and other risks identified by the press releases and securities filings of the other working interest owners in Israel and other jurisdictions in which such releases and filings are made. In light of the Israeli Supreme Court's decision, Bontan cannot assure that ITC will not proceed to consummate the Shaldieli transaction in contravention of agreements with Bontan and Bontan's vote against approving or proceeding with the transaction. Bontan's recent engagement of additional law firms, and further court efforts, including in defense of counterclaims from IPC Cayman and ITC, will entail the expenditure of significant funds and may not successfully protect Bontan's indirect share of the Working Interest in the Offshore Israel Project as Bontan's management intends. Bontan assumes no obligation and expressly disclaims any duty to update the information in this News Release.
