TORONTO, Dec. 19, 2011 /PRNewswire/ - Bontan Corporation Inc. (OTCBB: BNTNF) announces that it has entered into a settlement agreement  with IPC Cayman , International Three Crown Petroleum LLC ("ITCP"), Three Crown Petroleum LLC ( "TCP")  and Mr. Howard Cooper ("IPC Parties").

Under the terms and conditions stated in settlement agreement, all parties agree to settle the claims, differences and disputes between them while denying any liability to each other.

Bontan agrees to transfer all its equity in IPC Cayman on closing for a total price of US$15 million and a 0.25% Overriding Royalty Interest ("ORI") in the Israeli Project comprising two offshore Israeli drilling licenses # 348 Sara and # 347 Myra.  In addition, all 5 million warrants issued to ITC and 600,000 options issued to IPC Cayman consultants have been surrendered and cancelled without any compensation. The price of US$15 million will consist of cash of US$10 million. The balance is covered by two promissory notes carrying interest at 5% per annum and secured by additional ORI of 0.25%and a guarantee from IPC Cayman. One promissory note for US$2 million is payable on or before November 9, 2012 and another for US$3 million is payable on or before November 9, 2013. Bontan has received a non-refundable deposit of US$250,000. In the event of requests by the IPC Parties for an extension, or the occurrence of certain financing activities, Bontan may receive up to a further US$500,000 in non-refundable deposits. Bontan may also receive up to an additional US$ 3 million based on the price of IPC Oil and Gas Holdings Ltd ("Shaldieli" TASE:IPC) shares after two years.

Closing is conditioned on receipt or waiver of Regulatory Approval. If closing is not consummated, the situation will revert to the status quo that existed prior to signing except that Bontan will be able to retain certain deposited cash, cancelled warrants and options and the ORI.

Should closing not occur, all current lawsuits between the parties will carry on. All litigations between the parties have been stayed, pending dismissal at closing. The IPC Parties have until March 8, 2012 to deposit US$9,750,000 into escrow.  Should they not pay by that date, extensions may be granted upon payment of additional non-refundable deposits.

Mr. Kam Shah, CEO commented, "We believe that the settlement and sale as negotiated is in the best interests of our shareholders. As in any litigation, there is never assurance of success, and the prospect of continuing costly litigations was a factor in the Board's decision. Should the deal close as contemplated, Bontan will have made a good profit on the transaction with the possibility of some further upside through the holding of the ORI and the interest in the appreciation of Shaldieli shares. We wish IPC and its partners the best of luck. "

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 noncommercial 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. Bontan's recent settlement, if not closed as planned, will require it to renew 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 cannot assure that its claim to undo the Shaldieli transaction due to the fact that it was made in contravention of ITC's agreements with Bontan will succeed, or the extent of compensation which will be awarded to Bontan in lieu of such rescission, if such compensation is awarded. Bontan assumes no obligation and expressly disclaims any duty to update the information in this News Release.
