FORWARD LOOKING STATEMENTS

This annual report includes "forward-looking statements." All statements, other than statements of historical facts, included in this annual report that address activities, events or developments, which we expect or anticipate, will or may occur in the future are forward-looking statements.

The words "believe", "intend", "expect", "anticipate", "project", "estimate", "predict" and similar expressions are also intended to identify forward-looking statements.

These forward-looking statements address, among others, such issues as:

- - Future earnings and cash flow, - future plans and capital expenditures, - expansion and other development trends of the resource sector.

- - Expansion and growth of our business and operations, and

- Our prospective operational and financial information.

These statements are based on assumptions and analyses made by us in light of our experience and our perception of historical trends, current conditions and expected future developments, as well as other factors we believe are appropriate in particular circumstances. However, whether actual results and developments will meet our expectations and predictions depends on a number of risks and uncertainties, which could cause actual results to differ materially from our expectations, including the risks set forth in "Item 3-Key Information-Risk Factors" and the following:

-

Fluctuations in prices of our products and services,

-

Potential acquisitions and other business opportunities,

-

General economic, market and business conditions, and

-

Other risks and factors beyond our control.

Consequently, all of the forward-looking statements made in this annual report are qualified by these cautionary statements.

Unless the context indicates otherwise, the terms "Bontan Corporation Inc." the "Company”,"Bontan", “we”, “us”, “our” are used interchangeably in this Annual Report and mean Bontan Corporation Inc. and its subsidiaries.

FOREIGN PRIVATE ISSUER STATUS AND CURRENCIES AND EXCHANGE RATES

Foreign Private Issuer Status:

Bontan Corporation Inc. is a Canadian corporation incorporated under the laws of the Province of Ontario. Approximately 86% of its common stock is held by non-United States citizens and residents and our business is administered principally outside the United States; As a result, we believe that we qualify as a "foreign private issuer" for continuing to report regarding the registration of our common stock using this Form 20-F annual report format.

(D)  RISK FACTORS

The following is a brief discussion of those distinctive or special characteristics of the Company’s operations and industry that may have a material impact on, or constitute risk factors in respect of, the Company’s future financial performance.

We  have  a  history  of  operating  losses  and  may  not  achieve  or  sustain profitability in the future.

We have incurred significant operating losses during recent fiscal years. We have not yet had any revenue from the exploration activities nor have we ever found that development activity is warranted on any of our properties.  As of March 31, 2007, we had an accumulated deficit of approximately $32.0 million.  We currently have no interest in any oil or gas property or any natural resource project.

 

We expect to continue to incur losses until it is determined that properties in which we may acquire interests in the future can be sufficiently developed for commercialization. Even if it is determined that such properties should be developed for commercialization, there is no certainty that we will produce revenue, operate profitably or provide a return on investment in the future. We cannot assure you that we will be able to achieve or sustain profitable operations in the future.

We are in the process of seeking oil and gas opportunities and currently do not own any interests or properties.

Currently, we do not own any interest in any oil or gas project or any natural resource project.  We are assessing various opportunities, none of which may meet our eligibility requirements. Consequently, we may not own any interest for an indeterminate amount of time.  As a result, we will use our cash resources to pay for expenses and costs we incur in our efforts to identify appropriate opportunities as well as for our standard operating costs.

Our operations are subject to substantial exploration and development risks.

The Company anticipates participating in oil and gas resource properties in the hope of locating reserves.  The Company's property interests, when acquired will most likely be in the exploration stage only. Accordingly, there is little likelihood that the Company will realize any profits in the short to medium term. Any profitability in the future from the Company's business will be dependent upon locating reserves, which itself is subject to numerous risk factors.

The business of exploring for and producing oil and gas involves a substantial risk of investment loss which, even a combination of experience, knowledge and careful evaluation may not be able to overcome.  The principal resources necessary for the exploration and production of crude oil and natural gas are leasehold prospects under which crude oil and natural gas reserves may be discovered, drilling rigs and related equipment to explore for such reserves and knowledgeable personnel to conduct all phases of crude oil and natural gas operations, all of which requires a substantial investment.

Drilling oil and gas wells involves the risk that the wells will be unproductive or that, although productive, the wells do not produce oil and/or gas in economic quantities. Other hazards, such as unusual or unexpected geological formations, pressures, fires, blowouts, loss of circulation of drilling fluids or other conditions may substantially delay or prevent completion of any well. Adverse weather conditions can also hinder drilling operations.

A productive well may become uneconomic in the event water or other deleterious substances are encountered, which impair or prevent the production of oil and/or gas from the well.  In addition, production from any well may be unmarketable if it is impregnated with water or other deleterious substances.  As with any petroleum property, there can be no assurance that oil and gas will be produced from the properties in which the Company had and may in future have interests.  

 

In addition, the marketability of oil and gas, which may be acquired or discovered, will be affected by numerous factors beyond the control of the Company.  These factors include the proximity and capacity of oil and gas pipelines and processing equipment, market fluctuations of prices, taxes, royalties, land tenure, allowable production and environmental protection.  

The extent of these factors cannot be accurately predicted, but the combination of these factors may result in the Company not receiving an adequate return on invested capital. There is no assurance that our anticipated exploration and development activities in future resource properties will ultimately yield oil or gas in commercial quantities.  Drilling for oil and gas may be unprofitable. Dry holes and wells that are productive but do not produce sufficient net revenues after drilling, operating and other costs are unprofitable.  We cannot assure you that we will be able to achieve profitable operations in the future.

In determining the purchase price for our future interests, we will rely on both internal and external assessments relating to estimates of exploration, production and possible reserves that may prove to be materially inaccurate.

The price we are willing to pay for an interest in an oil and gas project is based on a combination of projected exploration and production costs and on the estimates of potential reserves. Actual costs and reserve could vary materially from these estimates. Consequently, the interests we acquire may be less unproductive than expected, or not productive at all, which could adversely affect us or cause us to lose our entire invest, or both.  Initial assessments of an interest will be based on a report by engineers or firms of engineers and these initial assessments may differ significantly from our subsequent assessments.

Our interests are subject to uninsurable risks.

Our industry also experiences numerous operating risks. These operating risks include the risk of fire, explosions, blow-outs, pipe failure, abnormally pressured formations and environmental hazards. Environmental hazards include oil spills, natural gas leaks, ruptures or discharges of toxic gases. Such events could result in substantial damage to oil and gas wells, producing facilities and other property and personal injury.  Although management believes the operator of any properties in which the Company and its subsidiaries may acquire interests, will acquire and maintain appropriate insurance coverage in accordance with standard industry practice, the Company and its subsidiaries may suffer losses from uninsurable hazards or from hazards which the operator has chosen not to insure against because of high premium costs or other reasons.  If any of these industry operating risks occur, the Company and its subsidiaries may face liability. &nbs p;The payment of any such liabilities may have a material, adverse effect on the Company's financial position.  We cannot assure you that insurance held by the operator of any of our properties will be adequate to cover losses or liabilities.

Environmental and other regulatory requirements may delay production and development of our resource interests.

 

The current or future operations of the Company, including development activities and commencement of production on its properties, require permits from various governmental authorities and such operations will be subject to laws and regulations governing prospecting, development, mining, production, exports, taxes, labour standards, occupational health, waste disposal, toxic substances, land use, environmental protection, safety and other matters. Companies engaged in the development and operation of natural resource properties and related facilities generally experience increased costs, and delays in production and other schedules as a result of the need to comply with applicable laws, regulations and permits.

There can be no assurance that approvals and permits required to commence production on its properties will be obtained.  Additional permits and studies, which may include environmental impact studies conducted before permits can be obtained, may be necessary prior to operation of the properties in which the Company acquires interests and there can be no assurance that the operator of these interests or the Company will be able to obtain or maintain all necessary permits that may be required to commence construction, development or operation of oil and gas extraction facilities at these properties on terms which enable operations to be conducted at economically justifiable costs.

 

Failure to comply with applicable laws, regulations, and permitting requirements may result in enforcement actions against the operator of any of our resource properties or us, including orders issued by regulatory or judicial authorities causing operations to cease or be curtailed, and may include corrective measures requiring capital expenditures, installation of additional equipment, or remedial actions.

 

Conducting business in foreign countries subjects us to special risks, which we have no control over.  

 

Company’s current business strategy may involve participation in overseas projects in the resource sector.  Consequently, the Company will be subject to certain risks associated with foreign ownership, including currency fluctuations, inflation, political instability and political risk. Oil, gas and other resource exploration and production activities in foreign countries may be affected in varying degrees by political stability and government regulations relating to the resource industry. Any changes in regulations or shifts in political conditions are beyond the control of the Company and may adversely affect its business. Operations may be affected in varying degrees by government regulations with respect to restrictions on production, price controls, export controls, restriction of earnings, taxation laws, expropriation of property, environmental legislation, water use and workplace safety.

Our short term investments are susceptible to market fluctuations and other risks.

We have approximately $6.3 million in cash ($3 million) and marketable securities ($3.3 million) as of March 31, 2007. Our marketable securities are primarily securities of publicly held Canadian corporations.  The value of these securities is subject to market fluctuations as well as the specific risks of each particular issuer.  Although we believe we have diversified our portfolio, we may lose some of our original investment in the event that an investment does not perform as anticipated.

Further, approximately $1.6 million or 48% of our investments are invested in one Canadian marketable security. While the market value of this security at March 31, 2007 was $2.7 million and continued at that level on May 10, 2007, the date of this report, there is no guarantee that the market price would continue to be higher than our cost. In the event, we are unable to or do not sell these securities on time and their market price gets adversely affected for whatever reasons, we may lose significant sum of money. We are minimising this risk by having all our investments monitored on a daily basis by consultants with substantial experience and knowledge of the investment market.

We will need to raise additional funds in the future, which may not be available to us.

The Company is currently without a source of revenue from operations and upon the investment of its current cash and liquidity, resources will most likely be required to issue additional securities to finance its operations and the development of its projects.  We may not be able to obtain additional financing on acceptable terms or at all. Failure to obtain additional financing on a timely basis could cause the Company to sell or forfeit its interest in its properties and reduce or terminate its operations on such properties or discontinue operations entirely.

There is a substantial risk of dilution through possible equity financings and stock options.

Any equity or debt financings, if available at all, may cause dilution to our then-existing shareholders. If additional funds are raised through the issuance of equity securities, the net tangible book value per share of our common shares would decrease and the percentage ownership of then current shareholders would be diluted.

Additionally, the Company may in the future grant to some or all of its own and its subsidiaries' directors, officers, insiders and key consultants options to purchase the Company's common shares as non-cash incentives to those people. Such options may be granted at exercise prices equal to market prices at time when the public market is depressed or below fair market value.  To the extent that significant numbers of such options may be granted and exercised, the interests of the then existing shareholders of the Company may be subject to additional dilution.

We are dependent upon our key managerial consultants, the loss of which would negatively affect our business.

Our performance depends on a small number of key managerial consultants. In particular, we believe our success is highly dependent upon the services of our Chief Executive Officer and Chief Financial Officer, Mr. Kam Shah, as well as Mr. Terence Robinson both of whom are consultants and who have been significantly involved in locating and negotiating our resource investments. Loss of either of their services could negatively affect our business.

Our officers and directors reside outside of the United States and there is a risk that civil liabilities and judgments may be unenforceable.

 

The Company and its officers and all but one of its directors are residents of countries other than the United States, and most of the Company's assets are located outside the United States.  As a result, it may not be possible for investors to effect service of process within the United States upon such persons or enforce in the United States against such persons judgments obtained in United States courts, including judgments predicated upon the civil liability provisions of United States federal securities laws or state securities laws.

 

Risk Factors Relating to Our Common Shares

Our share price has been volatile in the past and may decline in the future.

 

In recent years, the securities markets in Canada and the United States have experienced a high level of price and volume volatility, and the market prices of securities of many companies, particularly small mineral exploration companies like the Company, have experienced wide fluctuations which have not necessarily been related to the operating performance, underlying asset values or prospects of such companies.  Our shares may continue to experience significant market price and volume fluctuations in the future in response to factors, which are beyond our control.

Shares eligible for future sale may depress our stock price.    

At March 31, 2007, we had approximately 28.4 million shares of common stock outstanding. We also have approximately 13 million and 4.8 million shares of commons stock issuable under presently exercisable warrants and options, respectively, All such shares are registered pursuant to an effective registration statement under the Act and are eligible for resale in the public market.  Sales of shares of common stock pursuant to an effective registration statement or under Rule 144 or another exemption under the Act could have a material adverse effect on the price of our common stock and could impair our ability to raise additional capital through the sale of equity securities.

We do not intend to pay dividends.

 

All of the Company's available funds will be invested to finance the growth of the Company's business and therefore investors cannot expect and should not anticipate receiving a dividend on the Company's common shares in the foreseeable future.

Our common stock is subject to penny stock rules.

 

The capital stock of the Company would be classified as “penny stock” as defined in Reg. § 240.3a51-1 promulgated under the Securities Exchange Act of 1934 (the “1934 Act”).  In response to perceived abuse in the penny stock market generally, the 1934 Act was amended in 1990 to add new requirements in connection with penny stocks.  In connection with effecting any transaction in a penny stock, a broker or dealer must give the customer a written risk disclosure document that (a) describes the nature and level of risk in the market for penny stocks in both public offerings and secondary trading, (b) describes the broker’s or dealer’s duties to the customer and the rights and remedies available to such customer with respect to violations of such duties, (c) describes the dealer market, including “bid” and “ask” prices for penny stock and the significance of the spread between the bid and ask p rices, (d) contains a toll-free telephone number for inquiries on disciplinary histories of brokers and dealers, and (e) define significant terms used in the disclosure document or the conduct of trading in penny stocks.  In addition, the broker-dealer must provide to a penny stock customer a written monthly account statement that discloses the identity and number of shares of each penny stock held in the customer’s account, and the estimated market value of such shares.  The extensive disclosure and other broker-dealer compliance related to penny stocks may result in reducing the level of trading activity in the secondary market for such stocks, thus limiting the ability of the holder to sell such stock.

Your rights and responsibilities as a shareholder will be governed by Canadian law and differ in some respects from the rights and responsibilities of shareholders under U.S. law.

We are incorporated under Ontario Canada law. The rights and responsibilities of holders of our shares are governed by our memorandum of association, our articles of association and by Canadian law. These rights and responsibilities may differ in some respects from the rights and responsibilities of shareholders in typical U.S. corporations.

Changing regulation of corporate governance and public disclosure can cause additional expenses and failure to comply may adversely affect our reputation and the value of our securities.

Changing laws, regulations and standards relating to corporate governance and public disclosure, including the Sarbanes-Oxley Act of 2002, new SEC regulations and new and changing provisions of Canadian securities laws, are creating uncertainty because of the lack of specificity and varying interpretations of the rules. As a result, the application of the rules may evolve over time as new guidance is provided by regulatory and governing bodies, which could result in continuing uncertainty regarding compliance matters and higher costs necessitated by ongoing revisions to disclosure and governance practices. We are committed to maintaining high standards of corporate governance and public disclosure. As a result, our efforts to comply with evolving laws, regulations and standards have resulted in, and are likely to continue to result in, increased general and administrative expenses and a diversion of management time and attention from revenue-generating a ctivities to compliance activities. Any failure to comply with applicable laws may materially adversely affect our reputation and the value of our securities.

If we fail to comply with Section 404 of the Sarbanes-Oxley Act of 2002, our reputation and the value of our securities may be adversely affected.

Beginning with our annual report for the year ending March 31, 2008, Section 404 of the Sarbanes-Oxley Act of 2002 will require us to include an internal control report of management with our annual report on Form 20-F, which is to include management’s assessment of the effectiveness of our internal control over financial reporting as of the end of the fiscal year. That report will also be required to include a statement that our independent auditors have issued an attestation report on management’s assessment of our internal control over financial reporting. In order to achieve compliance with Section 404 within the prescribed period, management is in the process of adopting a detailed project work plan to assess the adequacy of our internal control over financial reporting, validate through testing that controls are functioning as documented, remediate any control weaknesses that may be identified, and implement a continuous reporting and imp rovement process for internal control over financial reporting. Any failure to comply with Section 404, including issuing the required management report and obtaining the attestation report on management’s assessment from our independent auditors, may materially adversely affect our reputation and the value of our securities.

If we lose our status as a foreign private issuer, our compliance costs will increase.

We are a "foreign private issuer" as defined under the Exchange Act. As a result, our proxy solicitations are not subject to the disclosure and procedural requirements of Regulation 14A under the Exchange Act and transactions in our equity securities by our officers and directors are exempt from Section 16 of the Exchange Act. In addition, we are not required under the Exchange Act to file periodic reports and financial statements as frequently or as promptly as U.S. companies whose securities are registered under the Exchange Act.   If we lose our status as a foreign private issuer by our election or otherwise, we will be subject to additional reporting obligations under the Exchange Act which could increase our cost of operations.

 

ITEM 4 – INFORMATION ON THE COMPANY

(A)  HISTORY AND DEVELOPMENT OF THE COMPANY

We are a Canadian corporation incorporated under the laws of the Province of Ontario.  Since April 2003, we have been a diversified natural resource company that invests in exploration, development and exploitation projects worldwide through our wholly-owned subsidiaries by acquiring joint venture, indirect and direct participation interests and working interests in those projects. During the fiscal year 2006, we sold our indirect participation interest in an oil exploration project and wrote off our working interest in a gas project owing to a dry test well. We currently do not own any interests in any oil or gas project or any natural resource project.  We are currently seeking opportunities to acquire oil and gas interests.  We have over $6.3 million in cash ($3 million) and marketable securities ($3.3 million) as of March 31, 2007.

We were originally incorporated under the Business Corporation Act (Ontario) in 1973 under the name Kamlo Gold Mines Limited and went through multiple name changes and five major changes in our business activities including a marine propulsion business, a snack food business, and an emerging technology investments business. Details of these changes are provided in our Registration Statement on Form 20-F dated June 12, 2000 and a summary is provided in our Annual Report on Form 20-F dated August 29, 2006.  On April 21, 2003, we changed our name to "Bontan Corporation Inc." when we adopted our business strategy to focus on the natural resource sector.

The Company’s registered office is situated at 47 Avenue Road, Suite 200,Toronto, Ontario, Canada M5R 2G3. The Company is a reporting issuer in the provinces of Ontario. The Company’s shares have been listed on the Over the Counter Bulletin Board (“OTCBB”) under the symbol “BNTNF” in the United States.

The following is a summary of our key past events:

a.

The Company was incorporated under the name “Kamlo Gold Mines Limited and remained an inactive shell from the date of incorporation to 1985.

b.

Between 1986 and 1982, the Company was involved in the development of a new technology for the marine propulsion business. During this period, the Company went through three name changes.

c.

Between 1993 and 1996, the Company was involved in the distribution and manufacture of a snack food. During this period, the Company went through two more name changes.

d.

The Company remained an inactive shell since the closure of snack food business in November 1996 until December 1998 when it changed its name to Dealcheck.com Inc. and agreed on a new business strategy. This strategy focused on investing in new and emerging technology oriented projects and businesses.

e.

In 1999, the company successfully raised $3.2 million, which were invested in various projects and companies over the next two years as per the new business strategy of the company. Unfortunately, IT sector performed poorly since 2001 and new and emerging technology-based businesses suffered significant losses, financial problems and bankruptcies. These factors adversely affected the company’s investments and its profitability. The company had to write off all its investments by the end of the fiscal 2003.

f.

In April 2003, the Company changed its business focus to resource industry based on the recommendations of its shareholders in the last shareholders’ meeting. At that time, the Company commenced and successfully completed a private placement of approximately 8.9 million common shares, raising approximately US$3.1 million. These funds were primarily invested in projects involving oil and gas exploration and diamond mining projects in Brazil between April 2003 and September 2005,

g.

Diamond mining operations discontinued in December 2004. The company sold its interest in an oil exploration project in Papua New Guinea in July 2005 for US$3.2 million. The Company’s cost of this project was approximately US$1.6 million. Further, in October 2004, the company acquired working interest in gas exploration project in Louisiana, USA.  Between March 2005 and September 2005, the company invested approximately $3.9 million as its share of exploration costs. The exploration however proved a dry well and was therefore abandoned and the costs incurred were fully written off in December 2005.

(B)  BUSINESS OVERVIEW

Our long-term business plan continues to be focused on becoming a diversified natural resource company that invests in major oil and gas exploration prospects. Through our wholly-owned subsidiaries, we will continue to seek highly visible opportunities in countries around the globe with a history of natural resource production that offer exciting and attractive propositions. We will seek to minimize risk by bringing in either joint venture, carried or working interest partners, depending on the size and scale of the project.  

It is our current belief that oil and gas exploration is a high priority all over the world and especially in North America. Higher price levels for both these natural resources which have occurred over the past twelve months encourage new drilling activities.  Our past experience with our two oil and gas projects enables us to more efficiently select and evaluate potential exploration projects in the oil and gas sector than in the other resource sectors.  During the past several months, we have received without solicitation opportunities to participate in oil and gas exploration projects as a result of our past involvement in similar projects.

Therefore, our current business model, based on our experience with resource projects handled over the recent past and our assumptions set forth above, envisions the following key features:

a.

We will focus only on oil and gas exploration projects;

b.

Preference will be given to projects that have proven but undeveloped reserves rather than probable or potential reserves;

 

c.

We will invest our resources in projects which involves multiple well exploration potentials;

d.

Preference will be given to explorations involving shallow wells (up to 7,500 ft.) rather than deep wells (over 15,000 ft.);

e.

Preference will be given to projects with other experienced partners who are involved in the project;

f.

We will attempt to allocate our cash or liquidity resources to more than one project.

However, if the Company is unable to find any suitable projects in oil and gas within a reasonable time, it may seek opportunities in other sectors, including alternative energy but not necessarily limited to the energy sector.

Income

Income comprised the following:

Fiscal year ended March 31	2007	2006	2005
Realised gain on disposal of short term investments	650,508	618,707	417,255
Interest	93,278	31,109	1,606
Gain on sale of interest in oil exploration project	-	1,207,831	-
	$743,786	$1,857,647	$418,861

Gains on disposal of short term investments

At the end of the fiscal 2006, the Company was able to retain a surplus cash of approximately $2 million after writing off its working interest in gas project, which failed to explore a producing well and after meeting its working capital requirements. In addition, the Company raised approximately $2.7 million from the private placement between February and April 2006 net of finder’s fee. The management began reviewing new oil and gas projects for potential participation.

Meanwhile, however, the management decided to invest the surplus funds on hand in short term marketable securities of companies primarily in the resource sector. The management believed that this would bring better returns than simply leaving the funds in bank deposits. The funds were invested through well known Canadian brokerage firms in securities trading on Canadian and US stock exchanges or Over the Counter Bulletin Boards.

By the end of the fiscal 2007, the Company realized a net gain of $650,508 and an unrealized gain of $ 959,701 on its investments. Average of approximately $2.6 million remained invested through the year.

By the end of the fiscal year 2006, the Company realized a net gain of $618,707 on these investments and the market value of its holdings exceeded the carrying value by $746,928. Average of approximately $1 million remained invested through the year.

During the fiscal 2005, The Company made a net capital gain of approx. $417,000 from disposal of 15,262 shares of Interoil Corporation that it received by converting part of its advances for a oil exploration project in Papua new Guinea made in fiscal 2004 and certain other shares of non related corporations that it bought as part of its temporary investments of surplus funds.

Interest Income

Interest was earned on cash funds held at the brokerage firms before they are being invested in marketable securities.

Significantly higher interest income in fiscal 2007 was mainly due to higher cash balances being held. Average cash during the fiscal 2007 was approximately $3.2 million compared to $2.1 million in fiscal 2006 and $700,000 in fiscal 2005.

Stock based compensation is made up of the Company’s common shares and options to acquire the Company’s common shares being issued to various consultants and directors of the Company for services provided. The Company used this method of payment mainly to conserve its cash flow for business investments purposes. This method also allows the Company to avail the services of consultants with specialized skills and knowledge in the business activities of the Company without having to deplete its limited cash flow.

During the fiscal 2007, the Company only registered one Plan and issued common shares to three existing consultants as explained below. No new consultants were hired due to lack of any active projects.

On January 16, 2007, the Company registered 2007 Consultant Stock Compensation Plan with the US Securities and Exchange Commission. The Company registered 1.7 million common shares under this Plan. On February 8, 2007, the company issued 1,150,000 common shares under this Plan to three existing consultants, who are all related parties, for a value of $313,486 based on the market price of the Company’s common shares on the date of their issuance.

The following table summarizes the stock granted by each consultant and nature of the services provided by the consultants:

#	Name	Period of service	# of shares to be issued	Market price (US$)	Fee in US$	CDN$ at	Brief description of services to be performed
						$1.1852
1	John Robinson (a)	Year ending June 30, 2008	300,000	$0.23	$69,000	$81,779	Searching and evaluating new oil and gas exploration project proposals and assisting Terence in managing our short term investment portfolios

			1,150,000		$264,500	$313,485

(a)

John has been providing consulting services for the last few years. These services mainly included review of oil and gas proposals that are received and short listing them for further review and analysis by CEO. In addition, John also does constant research on companies acquiring oil and gas interest and major oil and gas plays under consideration. The research has always proved useful in negotiating proper terms on any proposals and saved the company from over paying. During the past year, John also played an important role in managing our short term investments of around $6 million. These investments grew by over 100% during the period and provided the Company with a healthy cash flow. Owing to the above, we have extended John's contract for another year to June 30, 2008 and negotiated settlement of his fee for this period by issuance of the recommended number of shares.

(b)

Terence provides two main services to the company. Owing to his extensive network, he is constantly in touch with some of our key shareholders and potential investors to ensure that whenever the company needs additional funding, it can be easily raised through private placement. We had two such successful placements during the past five years. The second important service is business development through his network. The company receives lucrative proposals for acquiring interest in oil and gas projects from contacts known to Terence. Once we finalize such a project, he also helps secure best pricing. For the past few months, Terence was involved in deciding on the marketable securities in which the company's surplus funds got invested on a short term basis. Our funds grew by over 100% owing to his selection of the marketable securities and decisions to buy and sell at the right time. He will continue to provide these services during the year 2006 and has agreed to accept the proposed number of common shares in lieu of his fees for such services.

During fiscal 2006, the board of directors of the Company approved and created three new Plans, which were all registered with Securities and Exchange Commission of the United States of America as required under the Securities Act of 1933:

1.

2005 Consultant Stock Compensation Plan covering one million common shares, which were issued to five consultants including directors and key consultants of the company for their services and valued at $327,827. $60,398 was expensed in fiscal 2006 and the balance was deferred.

2.

The Robinson Plan covering 1.1 million options exercisable at an option price of US$0.50 per option to convert into equal number of common shares within five years to December 5, 2010. These options were granted to Mr. Terence Robinson, a key consultant for services rendered in connection with the sale of IPI interest in oil exploration project. These options were valued at $655,779 and were off set against the net gain from the sale as explained earlier in this report.

3.

2005 Stock Option Plan covering one million options. None of the options were granted to anyone as at March 31, 2006.

During fiscal 2005, approx. 929,000 shares were issued under the Consultants compensation plan to eleven consultants for services provided in fiscal 2005 and to be provided during the fiscal 2006. These shares were valued at the fair value, based on the market value on the date of issue, of approx. $1.2 million. Approx. 347,000 shares valuing at approx. $590,000 related to the services to be provided in the fiscal 2006 and have therefore been carried as deferred compensation while the remaining value was expensed in fiscal 2005.

During the fiscal 2005, the Company also allotted all the 5.5 registered Options to eleven individuals, which were valued at approx. $5.3 million using the Black-Scholes option-pricing model. Approx. $4.1 million was expensed and the balance 1.1 million was deferred. Further details on the Options are available in note 9 to the financial statements for fiscal 2005.

Exchange Loss

The Company’s reporting unit of currency is the Canadian dollar. At the year end, all transactions in US dollar and other currencies are translated using either average rate for the year or the rates on the dates of transactions depending upon the nature of the transactions. All assets and liabilities in non- Canadian currencies are translated at either the closing rate or rates on the dates of the underlying transactions again depending upon the nature of these balances.

During the fiscal 2007, the Company had an exchange loss of $111,659 on year end translation of foreign currency balances. The Company’s subsidiary, Bontan Oil & Gas Corporation has US dollar as a functional currency. The subsidiary owes to the parent company over US$ 3 million, which resulted in a translation loss at the year end on conversion of the US dollar balances into Canadian dollar due to strengthening of the value of the Canadian dollar versus US dollar. One US dollar was equal to Canadian dollar 1.15 at March 31, 2007 compared to 1.17 at March 31, 2006.

 

Similar trend between the two currencies gave rise to an exchange loss of $194,758 at March 31, 2006. One US dollar was equal to Canadian dollar 1.17 at March 31, 2006 compared to 1.22 at March 31, 2005.

Loss for the fiscal year 2005 was relatively small - $17,898 since most of the assets were non current and were translated at historical rate which was higher than the year end rate.

Loss from discontinued operations – for fiscal year 2005 only

There were no discontinued operations in fiscal 2006 and fiscal 2004.

In fiscal 2005, the Company discontinued its diamond mining operations in Brazil and decided to focus on oil and gas activities. The Company incurred losses of $179,678 from this discontinued operation during the fiscal 2005.

Losses were made up of expenses of approx. $121,000 relating to operations of the Brazilian office and approx. $55,000 relating to the costs of investments in two joint ventures, which was originally deferred but was written off on the closure of the operations.

Write off of interest in gas exploration project

On October 15, 2004, the Company entered into an exploration agreement with a private investors group in the United States under which it acquired 49% gross working interest in a gas exploration project in the State of Louisiana, USA (the project).

By September 20, 2005, the Company paid approximately US$3.5 million – CDN$ 4.3 million towards seismic survey, land leases and exploration costs of the first exploration test well, Placide Richard No.1, under the project.

The drilling began on August 21, 2005 and the targeted depth of 15,378’ was reached on October 19, 2005.

On October 21, 2005, the Company was informed by the project operators that based on electric log analysis and wireline formation tests results, the well could not be completed as a well capable of commercial production and therefore the well should be plugged and abandoned and all leases be allowed to expire.

Consequently, as at September 30, 2005, the management decided to write off the carrying value of the interest in the gas project in full.

Liquidity and Capital Resources

Working Capital

As at March 31, 2007, the Company had a net working capital of approximately $6.6 million compared to a working capital of $5.3 million as at March 31, 2006.

95% of the working capital - approximately $6.3 million - at March 31, 2007 was in the form of cash and short term investments compared to 94%  - $5 million at March 31, 2006.

Significant improvement in the liquid working capital was due to raising of equity through private placement and short term investments in marketable securities realising significant gains as explained earlier in this report.

Cash on hand as at March 31, 2007 was $3.0 million compared to $3.3 million as at March 31, 2006.

Operating cash flow

During the fiscal 2007, operating activities required net cash outflow of $529,323 which was off set by the net proceeds of $650,508 from the sale of short term investments. The Company was able to support its operating needs from the short term investment activities and was able to save the funds it raised from private placement for project investment purposes.

In fiscal 2006, the Company’s operating activities required net cash flow of $752,520 which was partly off set by the net proceeds from the sale of short term investments of $618,707 leaving a deficit of $133,813, which was financed from the funds raised through private placement.

The major decline in the operating cash requirement was due to the key management opting to shares and options in lieu of cash fees for their services.

Investment cash flows

During the fiscal 2007, the Company invested a net of $1.5 million in short term marketable securities while generating $650,508 from the sale of the short term marketable securities. These proceeds were primarily used for operational needs as explained above while funds raised through private placement were primarily used for investments.

There were three key investment activities during the fiscal 2006 that resulted in significant cash flows.

·

Sale of IPI interest in oil exploration project , as explained earlier in this report, generated a net cash flow of around $ 4 million – (US$ 3.2 million)

·

Approximately $3.7 million was spent on the gas exploration project in Louisiana during the fiscal year 2006.

·

A net sum of $1.7 million was invested in short term marketable securities through various brokerage firms, while generating $618,707 from the sale of short term marketable securities. The proceeds were used for the operational needs as explained above.

Overall investment activities in fiscal 2006 required a net cash outlay of $1.3 million before the net cash inflow form disposal of short term investments, which was primarily met from the equity funds raised under financing cash flows.

Financing cash flows

During the fiscal 2007, the Company raised an additional $1.2 million net of the finders’ fee from private placement which commenced in late fiscal 2006 and completed in April 2006.

The company generated approximately $4 million through financing activities during the fiscal 2006. The key financing activities in fiscal 2006 were as follows:

·

$2.2 million from exercise of warrants attached to the Units issued under the 2003 private placement.

·

Approximately $300,000 from exercise of options granted under various option plans discussed earlier in this report.

·

Approximately $1.7 million from a new private placement, which commenced on February 24, 2006 and completed on April 16, 2006.

The Company paid finder’s fee of $397,944 in connection with funds raised through warrant exercise and private placements during the fiscal 2006.

The Board held a total of 6 meetings during our financial year ended March 31, 2007.  To assist in the discharge of its responsibilities, the Board has designated one standing committee: an Audit Committee, as more particularly discussed below.

Audit Committee

The members of the audit committee consisted of Dean Bradley and Damian Lee until December 8, 2006 when Mr. Lee resigned and was replaced by Mr. Brett Rees as an independent director who became another member of the audit committee. The audit committee is charged with overseeing the Company's accounting and financial reporting policies, practices and internal controls.

Audit Committee charter assists the Board in fulfilling its responsibilities for our accounting and financial reporting practices by:

reviewing the quarterly and annual consolidated financial statements and management discussion and analyses;

meeting at least annually with our external auditor;

·

reviewing the adequacy of the system of internal controls in consultation with the chief executive and financial officer;

·

reviewing any relevant accounting and financial matters including reviewing our public disclosure of information extracted or derived from our financial statements;

establishing procedures for the receipt, retention and treatment of complaints received by us regarding accounting, internal controls or auditing matters and the confidential, anonymous submission by employees of concerns regarding questionable accounting or auditing matters;

reviewing and approving our hiring policies regarding personnel of our present and former external auditor

A copy of the Audit Committee Charter can be requested by calling (416) 929-1806.

Compensation Committee

The Company does not currently have a Compensation Committee. The directors determined that, in light of the Company’s size and resources, setting up such a committee would be too expensive and would not serve any useful purpose for the Company at this time. The Company has, however, set up an Independent Review Committee of the Board to review and approve all non-arms' length contracts. This Committee has the same composition as the Audit Committee, and is currently comprised of the two independent directors - Dean Bradley and Brett Rees.

(C)  MARKETS

The Company’s common shares were traded on the Over the Counter Bulletin Board (OTCBB) under the symbol “DEAL” and on Canadian Dealing Network (CDN) under the symbol “FDQI” until January 20, 1999.

Effective January 21, 1999. The Company’s shares were traded only on OTCBB. The symbol was further changed to “NMBC” on August 13, 1999 and then to “DCHK” on November 3, 1999.

On May 26, 2000, the Company shares were de-listed from OTCBB and began trading on the “Pink Sheet” pending clearance of the Registration Statement, F-20 by Securities and Exchange Commission (SEC). The Company filed F-20 originally in December 1999 and then filed several amendments in response to the comments received from SEC to its submissions. The SEC clearance was finally received on June 16, 2000 and the common shares of the Company began trading again on OTCBB effective August 2, 2000.

The company changed its name to Bontan Corporation Inc.  On April 21, 2003 and its common shares began trading, and currently trade under a new symbol “BNTNF” on OTCBB.

ITEM 10 – ADDITIONAL INFORMATION

(A)  SHARE CAPITAL

This Form 20F is being filed as an Annual Report under the Exchange Act and, as such, there is no requirement to provide any information under this section.

(B)  MEMORANDUM AND ARTICLES OF ASSOCIATION

The Memorandum and Articles of the Company are incorporated by reference to the information in our registration statement on Form 20-F filed with the Securities and Exchange Commission, in Washington, D.C. on June 12, 2000 to which our Articles of Incorporation and Memorandum were filed as exhibits.

No further changes have been made to the Company’s Articles/Bylaws.

(C) MATERIAL CONTRACTS

Except for contracts entered into in the ordinary course of its business, the only material contracts to which we are or have been a party to for the two years preceding this annual report is as follows:

1.

Agreement dated July 5, 2005 with Kings Road Investments Limited for sale of indirect participation interest in oil exploration project in Papua New Guinea.

2.

Private Placement Agreement dated February 24, 2006 for issuance of Units consisting of common shares and common share purchase warrants to a group of accredited investors.

(D) EXCHANGE CONTROLS

Limitations on the ability to acquire and hold shares of the Company may be imposed by the Competition Act (Canada) (the “Competition Act”).  This legislation permits the Commissioner of Competition to review any acquisition of a significant interest in us. This legislation grants the Commissioner jurisdiction, for up to three years, to challenge this type of acquisition before the Competition Tribunal if the Commissioner believes that it would, or would be likely to, result in a substantial lessening or prevention of competition in any market in Canada.

The Competition Act requires that any person proposing to acquire any of the assets in Canada of an operating business file a notification with the Competition Bureau where (a) the parties to the transaction, together with their respective affiliates, have (i) assets in Canada the value of which exceeds $400,000,000 in the aggregate, or (ii) annual gross revenues from sales in, from or into Canada that exceed $400,000,000 in the aggregate; and (b) the aggregate value of those assets, or the gross revenues from sales in or from Canada generated from those assets, would exceed $50,000,000.  For the purposes of the Competition Act, asset values and gross revenues are to be determined as of the last day of the period covered by the most recent audited financial statements in which the assets or gross revenues are accounted for.

This legislation also requires any person who intends to acquire shares to file a notification with the Competition Bureau if certain financial thresholds are exceeded, and that person would hold more than 20% of our voting shares as a result of the acquisition.  If a person already owns 20% or more of our voting shares, a notification must be filed when the acquisition would bring that person’s holdings over 50%.  Where a notification is required, the legislation prohibits completion of the acquisition until the expiration of a statutory waiting period, unless the Commissioner provides written notice that he does not intend to challenge the acquisition.

There are no governmental laws, decrees or regulations in Canada that restrict the export or import of capital or that affect the remittance of dividends, interest or other payments to non-resident holders of our securities.  However, any such remittance to a resident of the United States may be subject to a withholding tax pursuant to the Income Tax Act (Canada).  For further information concerning such withholding tax, see “Taxation" below.

Except as may be provided under the Investment Canada Act (the "ICA"), there are no specific limitations under the laws of Canada, the Province of Ontario, or in the Notice of Articles and Articles of the Company with respect to the rights of non-residents of Canada to hold and/or vote securities of the Company.

The ICA requires each individual, government or agency thereof, corporation, partnership, trust or joint venture that is not a “Canadian” as defined in the ICA (a “non-Canadian”) making an investment to acquire control of a Canadian business, the gross assets of which exceed certain defined threshold levels, to file an application for review with the Investment Review Division of Industry Canada.  The current threshold level for non-Canadians who are World Trade Organization investors (as defined in the ICA) is $265,000,000 (in 2006).  This amount is subject to an annual adjustment on the basis of a prescribed formula in the ICA to reflect inflation and real growth within Canada.

In the context of the Company, in essence, three methods of acquiring control of a Canadian business are regulated by the ICA: (i) the acquisition of all or substantially all of the assets used in carrying on business in Canada; (ii) the acquisition, directly or indirectly, of voting shares of a Canadian corporation carrying on business in Canada; (iii) the acquisition of voting shares of an entity which controls, directly or indirectly, another entity carrying on business in Canada.  An acquisition of a majority of the voting interests of an entity, including a corporation, is deemed to be an acquisition of control under the ICA.  However, under the ICA, there is a rebuttable presumption that control is acquired if one-third of the voting shares of a Canadian corporation or an equivalent undivided interest in the voting shares of such corporation are held by a non-Canadian person or entity.  A n acquisition of less than one-third of the voting shares of a Canadian corporation is deemed not to be an acquisition of control.  An acquisition of less than a majority, but one-third or more, of the voting shares of a Canadian corporation is presumed to be an acquisition of control unless it can be established that on the acquisition the Canadian corporation is not, in fact, controlled by the acquirer through the ownership of voting shares.  Certain transactions relating to the acquisition of common shares would be exempt from review from the ICA, including:

(a) acquisition of common shares by a person in the ordinary course of a person’s business as a trader or dealer in securities;

(b) acquisition of control of a Canadian corporation in connection with the realization of security granted for a loan or other financial assistance and not for any purpose related to the provisions of the ICA; and

(c) acquisition of control of a Canadian corporation by reason of an amalgamation, merger, consolidation or corporate reorganization following which the ultimate direct or indirect control in fact of the corporation, through the ownership of voting interests, remains unchanged.

In addition, if less than a majority of voting interests of a Canadian corporation are owned by Canadians, the acquisition of control of any other Canadian corporation by such corporation may be subject to review unless it can be established that the corporation is not in fact controlled through the ownership of voting interests and that two-thirds of the members of the board of directors of the corporation are Canadians.

Where an investment is reviewable under the ICA, it may not be implemented unless it is likely to be of net benefit to Canada.  If an applicant is unable to satisfy the Minister responsible for Industry Canada that the investment is likely to be of net benefit to Canada, the applicant may not proceed with the investment.  Alternatively, an acquirer may be required to divest control of the Canadian business that is the subject of the investment.

In addition to the foregoing, the ICA requires formal notification to the Canadian government of all other acquisitions of control of Canadian businesses by non-Canadians.  These provisions require a foreign investor to give notice in the required form, which notices are for information, as opposed to review purposes.

(E)  TAXATION

Canadian Federal Income Tax Consequences

We consider that the following general summary fairly describes the principal Canadian federal income tax considerations applicable to holders of our common shares who, for purposes of the Income Tax Act (Canada) (the “ITA”), deal at arm’s length with the Company, hold such shares as capital property, do not carry on business in Canada, have not been at any time residents of Canada for purposes of the ITA and are residents of the United States (“US Residents”) under the Canada-United States Income Tax Convention as amended by the Protocols thereto (the “Convention”).

This summary is based upon the current provisions of the ITA, the Income Tax Regulations (the “Regulations”), the current publicly announced administrative and assessing policies of the Canada Revenue Agency (formerly Canada Customs and Revenue Agency), and all specific proposals (the “Tax Proposals”) to amend the ITA and Regulations publicly announced prior to the date hereof by the Minister of Finance (Canada).  This description is not exhaustive of all possible Canadian federal income tax consequences and, except for the Tax Proposals, does not take into account or anticipate any changes in law, whether by legislative, governmental or judicial action, nor does it take into account provincial or foreign tax considerations which may differ significantly from those discussed herein.

The following discussion is for general information only and it is not intended to be, nor should it be construed to be, legal or tax advice to any holder or prospective holder of our common shares and no opinion or representation with respect to any Canadian federal, provincial or foreign tax consequences to any such holder or prospective holder is made. Accordingly, holders and prospective holders of our common shares should consult with their own tax advisors about the Canadian federal, provincial and foreign tax consequences of purchasing, owning and disposing of our common shares.

Dividends

The ITA provides that dividends and other distributions deemed to be dividends paid or deemed to be paid by a Canadian resident corporation (such as our Company) to a non-resident of Canada shall be subject to a non-resident withholding tax equal to 25% of the gross amount of the dividend or deemed dividend. Provisions in the ITA relating to dividend and deemed dividend payments to and gains realized by non-residents of Canada, who are residents of the United States, are subject to the Treaty. The Treaty may reduce the withholding tax rate on dividends as discussed below.

The Convention provides a 5% withholding tax on gross dividends or deemed dividends paid to a United States corporation which beneficially owns at least 10% of the voting stock of the company paying the dividend. In cases where dividends or deemed dividends are paid to a United States resident (other than a corporation) or a United States corporation which beneficially owns less than 10% of the voting stock of a company, a withholding tax of 15% is imposed on the gross amount of the dividend or deemed dividend paid. We would be required to withhold any such tax from the dividend and remit the tax directly to CRA for the account of the investor.

The reduction in withholding tax from 25%, pursuant to the Treaty, will not be available:

(a)

if the shares in respect of which the dividends are paid formed part of the business property or were otherwise effectively connected with a permanent establishment or fixed base that the holder has or had in Canada within the 12 months preceding the disposition, or

(b)

the holder is a U.S. LLC which is not subject to tax in the U.S.

The Convention generally exempts from Canadian income tax dividends paid to a religious, scientific, literary, educational or charitable organization or to an organization exclusively administering a pension, retirement or employee benefit fund or plan, if the organization is resident in the U.S. and is exempt from income tax under the laws of the U.S.

Capital Gains

The Convention provides that a US Resident will not be subject to tax under the ITA in respect of any capital gain on the disposition of our common shares unless such shares constitute taxable Canadian property of the US Resident and the US Resident is not entitled to the benefits of the Convention with regards to capital gains. Our common shares will constitute taxable Canadian property if at any time during the five year period immediately preceding the disposition of our common shares, the US Resident, or persons with whom the US Resident did not deal at arm’s length, or the US Resident together with persons with whom the US resident did not deal at arm’s length owned 25% or more of the issued shares of any class of our capital stock.

Where a US resident realizes a capital gain on a disposition of shares that constitute “taxable Canadian property”, the Convention relieves the US resident from liability for Canadian tax on such capital gains unless:

(a)

the value of the shares is derived principally from “real property” in Canada, including the right to explore for or exploit natural resources and rights to amounts computed by reference to production;

(b)

the shareholder was resident in Canada for 120 months during any period of 20 consecutive years preceding the disposition, was resident in Canada at any time during the 10 years immediately preceding the disposition and the shares were owned by him when he ceased to be resident in Canada;

(c)

the shares formed part of the business property of a “permanent establishment” or pertained to a fixed base used for the purpose of performing independent personal services that the shareholder has or had in Canada within the 12 months preceding the disposition, or

(d)      

the holder is a U.S. LLC which is not subject to tax in the U.S.

If subject to Canadian tax on such a disposition, the taxpayer's capital gain (or capital loss) from a disposition is the amount by which the taxpayer's proceeds of disposition exceed (or are exceeded by) the aggregate of the taxpayer's adjusted cost base of the shares and reasonable expenses of disposition. For Canadian income tax purposes, the "taxable capital gain" is equal to one-half of the capital gain.

U.S. Federal Income Tax Consequences

The following is a summary of the anticipated material U.S. federal income tax consequences to a U.S. Holder (as defined below) arising from and relating to the acquisition, ownership, and disposition of our common shares (“Common Shares”).

This summary is for general information purposes only and does not purport to be a complete analysis or listing of all potential U.S. federal income tax consequences that may apply to a U.S. Holder as a result of the acquisition, ownership, and disposition of Common Shares.  In addition, this summary does not take into account the individual facts and circumstances of any particular U.S. Holder that may affect the U.S. federal income tax consequences of the acquisition, ownership, and disposition of Common Shares.  Accordingly, this summary is not intended to be, and should not be construed as, legal or U.S. federal income tax advice with respect to any U.S. Holder.  Each U.S. Holder should consult its own financial advisor, legal counsel, or accountant regarding the U.S. federal, U.S. state and local, and foreign tax consequences of the acquisition, ownership, and disposition of Common Shares.

Scope of this Disclosure

Authorities

This summary is based on the Internal Revenue Code of 1986, as amended (the “Code”), Treasury Regulations (whether final, temporary, or proposed), published rulings of the Internal Revenue Service (“IRS”), published administrative positions of the IRS, the Convention Between Canada and the United States of America with Respect to Taxes on Income and on Capital, signed September 26, 1980, as amended (the “Canada-U.S. Tax Convention”), and U.S. court decisions that are applicable and, in each case, as in effect and available, as of the date of this Annual Report.  Any of the authorities on which this summary is based could be changed in a material and adverse manner at any time, and any such change could be applied on a retroactive basis.  This summary does not discuss the potential effects, whether adverse or beneficial, of any proposed legislation that, if enacted, could be applied on a retroactive basis.

U.S. Holders

For purposes of this summary, a “U.S. Holder” is a beneficial owner of Common Shares that, for U.S. federal income tax purposes, is (a) an individual who is a citizen or resident of the U.S., (b) a corporation, or any other entity classified as a corporation for U.S. federal income tax purposes, that is created or organized in or under the laws of the U.S. or any state in the U.S., including the District of Columbia, (c) an estate if the income of such estate is subject to U.S. federal income tax regardless of the source of such income, or (d) a trust if (i) such trust has validly elected to be treated as a U.S. person for U.S. federal income tax purposes or (ii) a U.S. court is able to exercise primary supervision over the administration of such trust and one or more U.S. persons have the authority to control all substantial decisions of such trust.

Non-U.S. Holders

For purposes of this summary, a “non-U.S. Holder” is a beneficial owner of Common Shares other than a U.S. Holder.  This summary does not address the U.S. federal income tax consequences of the acquisition, ownership, and disposition of Common Shares to non-U.S. Holders.  Accordingly, a non-U.S. Holder should consult its own financial advisor, legal counsel, or accountant regarding the U.S. federal, U.S. state and local, and foreign tax consequences (including the potential application of and operation of any tax treaties) of the acquisition, ownership, and disposition of Common Shares.

U.S. Holders Subject to Special U.S. Federal Income Tax Rules Not Addressed

This summary does not address the U.S. federal income tax consequences of the acquisition, ownership, and disposition of Common Shares to U.S. Holders that are subject to special provisions under the Code, including the following U.S. Holders:  (a) U.S. Holders that are tax-exempt organizations, qualified retirement plans, individual retirement accounts, or other tax-deferred accounts; (b) U.S. Holders that are financial institutions, insurance companies, real estate investment trusts, or regulated investment companies; (c) U.S. Holders that are dealers in securities or currencies or U.S. Holders that are traders in securities that elect to apply a mark-to-market accounting method; (d) U.S. Holders that have a “functional currency” other than the U.S. dollar; (e) U.S. Holders that are liable for the alternative minimum tax under the Code; (f) U.S. Holders that own Common Shares as part of a straddle, hedging t ransaction, conversion transaction, constructive sale, or other arrangement involving more than one position; (g) U.S. Holders that acquired Common Shares in connection with the exercise of employee stock options or otherwise as compensation for services; (h) U.S. Holders that hold Common Shares other than as a capital asset within the meaning of Section 1221 of the Code; or (i) U.S. Holders that own, directly or indirectly, 10% or more, by voting power or value, of our outstanding shares.  U.S. Holders that are subject to special provisions under the Code, including U.S. Holders described immediately above, should consult their own financial advisor, legal counsel or accountant regarding the U.S. federal, U.S. state and local, and foreign tax consequences of the acquisition, ownership, and disposition of Common Shares.

If an entity that is classified as partnership (or “pass-through” entity) for U.S. federal income tax purposes holds Common Shares, the U.S. federal income tax consequences to such partnership (or “pass-through” entity) and the partners of such partnership (or owners of such “pass-through” entity) generally will depend on the activities of the partnership (or “pass-through” entity) and the status of such partners (or owners).  Partners of entities that are classified as partnerships (or owners of “pass-through” entities) for U.S. federal income tax purposes should consult their own financial advisor, legal counsel or accountant regarding the U.S. federal income tax consequences of the acquisition, ownership, and disposition of Common Shares.

Tax Consequences Other than U.S. Federal Income Tax Consequences Not Addressed

This summary does not address the U.S. state and local, U.S. federal estate and gift, or foreign tax consequences to U.S. Holders of the acquisition, ownership, and disposition of Common Shares.  Each U.S. Holder should consult its own financial advisor, legal counsel, or accountant regarding the U.S. state and local, U.S. federal estate and gift, and foreign tax consequences of the acquisition, ownership, and disposition of Common Shares.  (See “Taxation—Canadian Federal Income Tax Consequences” above).

U.S. Federal Income Tax Consequences of the Acquisition, Ownership, and Disposition of Common Shares

Distributions on Common Shares

General Taxation of Distributions

A U.S. Holder that receives a distribution, including a constructive distribution, with respect to the Common Shares will be required to include the amount of such distribution in gross income as a dividend (without reduction for any Canadian income tax withheld from such distribution) to the extent of our current or accumulated “earnings and profits”.  To the extent that a distribution exceeds our current and accumulated “earnings and profits”, such distribution will be treated (a) first, as a tax-free return of capital to the extent of a U.S. Holder’s tax basis in the Common Shares and, (b) thereafter, as gain from the sale or exchange of such Common Shares.  (See more detailed discussion at “Disposition of Common Shares” below).  

Reduced Tax Rates for Certain Dividends

For taxable years beginning after December 31, 2002 and before January 1, 2011, a dividend paid by us generally will be taxed at the preferential tax rates applicable to long-term capital gains if (a) we are a “qualified foreign corporation” (as defined below), (b) the U.S. Holder receiving such dividend is an individual, estate, or trust, and (c) such dividend is paid on Common Shares that have been held by such U.S. Holder for at least 61 days during the 121-day period beginning 60 days before the “ex-dividend date” (i.e., the first date that a purchaser of such Common Shares will not be entitled to receive such dividend).

We generally will be a “qualified foreign corporation” under Section 1(h)(11) of the Code (a “QFC”) if (a) we are incorporated in a possession of the U.S., (b) we are eligible for the benefits of the Canada-U.S. Tax Convention, or (c) the Common Shares are readily tradable on an established securities market in the U.S.  However, even if we satisfy one or more of such requirements, we will not be treated as a QFC if we are a “passive foreign investment company” (as defined below) for the taxable year during which we pay a dividend or for the preceding taxable year.  In 2003, the U.S. Department of the Treasury (the “Treasury”) and the IRS announced that they intended to issue Treasury Regulations providing procedures for a foreign corporation to certify that it is a QFC.  Although these Treasury Regulations were not issued in 2004, the Treasury and the IRS have confirmed their int ention to issue these Treasury Regulations.  It is expected that these Treasury Regulations will obligate persons required to file information returns to report a distribution with respect to a foreign security issued by a foreign corporation as a dividend from a QFC if the foreign corporation has, among other things, certified under penalties of perjury that the foreign corporation was not a “passive foreign investment company” for the taxable year during which the foreign corporation paid the dividend or for the preceding taxable year.  

As discussed below, we believe that we might be considered a “passive foreign investment company” for the taxable year ended March 31, 2007. There can be no assurance that we will not be a “passive foreign investment company” for the current or any future taxable year.  Accordingly, there can be no assurances that we will be a QFC for the current or any future taxable year, or that we will be able to certify that it is a QFC in accordance with the certification procedures issued by the Treasury and the IRS.

If we are not a QFC, a dividend paid by us to a U.S. Holder, including a U.S. Holder that is an individual, estate, or trust, generally will be taxed at ordinary income tax rates (and not at the preferential tax rates applicable to long-term capital gains).  The dividend rules are complex, and each U.S. Holder should consult its own financial advisor, legal counsel, or accountant regarding the dividend rules.

Distributions Paid in Foreign Currency

The amount of a distribution paid to a U.S. Holder in foreign currency generally will be equal to the U.S. dollar value of such distribution based on the exchange rate applicable on the date of receipt.  A U.S. Holder that does not convert foreign currency received as a distribution into U.S. dollars on the date of receipt generally will have a tax basis in such foreign currency equal to the U.S. dollar value of such foreign currency on the date of receipt.  Such a U.S. Holder generally will recognize ordinary income or loss on the subsequent sale or other taxable disposition of such foreign currency (including an exchange for U.S. dollars).

Dividends Received Deduction

Dividends paid on the Common Shares generally will not be eligible for the “dividends received deduction.”  The availability of the dividends received deduction is subject to complex limitations that are beyond the scope of this discussion, and a U.S. Holder that is a corporation should consult its own financial advisor, legal counsel, or accountant regarding the dividends received deduction.

Disposition of Common Shares

A U.S. Holder will recognize gain or loss on the sale or other taxable disposition of Common Shares in an amount equal to the difference, if any, between (a) the amount of cash plus the fair market value of any property received and (b) such U.S. Holder’s tax basis in the Common Shares sold or otherwise disposed of.  Any such gain or loss generally will be capital gain or loss, which will be long-term capital gain or loss if the Common Shares are held for more than one year.  Gain or loss recognized by a U.S. Holder on the sale or other taxable disposition of Common Shares generally will be treated as “U.S. source” for purposes of applying the U.S. foreign tax credit rules.   (See more detailed discussion at “Foreign Tax Credit” below).  

Preferential tax rates apply to long-term capital gains of a U.S. Holder that is an individual, estate, or trust.  There are currently no preferential tax rates for long-term capital gains of a U.S. Holder that is a corporation.  Deductions for capital losses and net capital losses are subject to complex limitations.  For a U.S. Holder that is an individual, estate, or trust, capital losses may be used to offset capital gains and up to US$3,000 of ordinary income.  An unused capital loss of a U.S. Holder that is an individual, estate, or trust generally may be carried forward to subsequent taxable years, until such net capital loss is exhausted.  For a U.S. Holder that is a corporation, capital losses may be used to offset capital gains, and an unused capital loss generally may be carried back three years and carried forward five years from the year in which such net capital loss is recognized.  

Foreign Tax Credit

A U.S. Holder who pays (whether directly or through withholding) Canadian income tax with respect to dividends paid on the Common Shares generally will be entitled, at the election of such U.S. Holder, to receive either a deduction or a credit for such Canadian income tax paid.  Generally, a credit will reduce a U.S. Holder’s U.S. federal income tax liability on a dollar-for-dollar basis, whereas a deduction will reduce a U.S. Holder’s income subject to U.S. federal income tax.  This election is made on a year-by-year basis and applies to all foreign taxes paid (whether directly or through withholding) by a U.S. Holder during a year.  

Complex limitations apply to the foreign tax credit, including the general limitation that the credit cannot exceed the proportionate share of a U.S. Holder’s U.S. federal income tax liability that such U.S. Holder’s “foreign source” taxable income bears to such U.S. Holder’s worldwide taxable income.  In applying this limitation, a U.S. Holder’s various items of income and deduction must be classified, under complex rules, as either “foreign source” or “U.S. source.”  In addition, this limitation is calculated separately with respect to specific categories of income (including “passive income,” “high withholding tax interest,” “financial services income,” “general income,” and certain other categories of income).  Dividends paid by us generally will constitute “foreign source” income and generally will be categorized as “passive income ” or, in the case of certain U.S. Holders, “financial services income.”  However, for taxable years beginning after December 31, 2006, the foreign tax credit limitation categories are reduced to “passive income” and “general income” (and the other categories of income, including “financial services income,” are eliminated).  The foreign tax credit rules are complex, and each U.S. Holder should consult its own financial advisor, legal counsel, or accountant regarding the foreign tax credit rules.

Information Reporting; Backup Withholding Tax

Payments made within the U.S., or by a U.S. payor or U.S. middleman, of dividends on, and proceeds arising from certain sales or other taxable dispositions of, Common Shares generally will be subject to information reporting and backup withholding tax, at the rate of 28%, if a U.S. Holder (a) fails to furnish such U.S. Holder’s correct U.S. taxpayer identification number (generally on Form W-9), (b) furnishes an incorrect U.S. taxpayer identification number, (c) is notified by the IRS that such U.S. Holder has previously failed to properly report items subject to backup withholding tax, or (d) fails to certify, under penalty of perjury, that such U.S. Holder has furnished its correct U.S. taxpayer identification number and that the IRS has not notified such U.S. Holder that it is subject to backup withholding tax.  However, U.S. Holders that are corporations generally are excluded from these information reporting and backup withholding tax rules.  Any amounts withheld under the U.S. backup withholding tax rules will be allowed as a credit against a U.S. Holder’s U.S. federal income tax liability, if any, or will be refunded, if such U.S. Holder furnishes required information to the IRS. Each U.S. Holder should consult its own financial advisor, legal counsel, or accountant regarding the information reporting and backup withholding tax rules.

Additional Rules that May Apply to U.S. Holders

If we are a “controlled foreign corporation,” or a “passive foreign investment company” (each as defined below), the preceding sections of this summary may not describe the U.S. federal income tax consequences to U.S. Holders of the acquisition, ownership, and disposition of Common Shares.

Controlled Foreign Corporation

We generally will be a “controlled foreign corporation” under Section 957 of the Code (a “CFC”) if more than 50% of the total voting power or the total value of our outstanding shares are owned, directly or indirectly, by citizens or residents of the U.S., domestic partnerships, domestic corporations, domestic estates, or domestic trusts (each as defined in Section 7701(a)(30) of the Code), each of which own, directly or indirectly, 10% or more of the total voting power of our outstanding shares (a “10% Shareholder”).

If we are a CFC, a 10% Shareholder generally will be subject to current U.S. federal income tax with respect to (a) such 10% Shareholder’s pro rata share of the “subpart F income” (as defined in Section 952 of the Code) of the Company and (b) such 10% Shareholder’s pro rata share of our earnings invested in “United States property” (as defined in Section 956 of the Code).  In addition, under Section 1248 of the Code, any gain recognized on the sale or other taxable disposition of Common Shares by a U.S. Holder that was a 10% Shareholder at any time during the five-year period ending with such sale or other taxable disposition generally will be treated as a dividend to the extent of the “earnings and profits” of the Company that are attributable to such Common Shares.  If we are both a CFC and a “passive foreign investment company” (as defined below), we ge nerally will be treated as a CFC (and not as a “passive foreign investment company”) with respect to any 10% Shareholder.  

We do not believe that Bontan has previously been, or currently is a CFC.  However, there can be no assurance that we will not be a CFC for the current or any future taxable year.

Passive Foreign Investment Company

We generally will be a “passive foreign investment company” under Section 1297 of the Code (a “PFIC”) if, for a taxable year, (a) 75% or more of our gross income for such taxable year is passive income or (b) 50% or more of the assets held by us either produce passive income or are held for the production of passive income, based on the fair market value of such assets (or on the adjusted tax basis of such assets, if we are not publicly traded and either is a “controlled foreign corporation” or makes an election). “Passive income” includes, for example, dividends, interest, certain rents and royalties, certain gains from the sale of stock and securities, and certain gains from commodities transactions.  

For purposes of the PFIC income test and asset test described above, if we own, directly or indirectly, 25% or more of the total value of the outstanding shares of another foreign corporation, we will be treated as if it (a) held a proportionate share of the assets of such other foreign corporation and (b) received directly a proportionate share of the income of such other foreign corporation.  In addition, for purposes of the PFIC income test and asset test described above, “passive income” does not include any interest, dividends, rents, or royalties that are received or accrued by us from a “related person” (as defined in Section 954(d)(3) of the Code), to the extent such items are properly allocable to the income of such related person that is not passive income.  

We believe that Bontan has during the fiscal year 2007 and is currently a PFIC since we do not have any active projects and our surplus funds are being held in short term investments and our main sources of revenue are gains from disposal of these investments and interest on the funds on hand. 

Default PFIC Rules Under Section 1291 of the Code

If we are a PFIC, the U.S. federal income tax consequences to a U.S. Holder of the acquisition, ownership, and disposition of Common Shares will depend on whether such U.S. Holder makes an election to treat the Company as a “qualified electing fund” or “QEF” under Section 1295 of the Code (a “QEF Election”) or a mark-to-market election under Section 1296 of the Code (a “Mark-to-Market Election”).  A U.S. Holder that does not make either a QEF Election or a Mark-to-Market Election will be referred to in this summary as a “Non-Electing U.S. Holder.”

A Non-Electing U.S. Holder will be subject to the rules of Section 1291 of the Code with respect to (a) any gain recognized on the sale or other taxable disposition of Common Shares and (b) any excess distribution paid on the Common Shares.  A distribution generally will be an “excess distribution” to the extent that such distribution (together with all other distributions received in the current taxable year) exceeds 125% of the average distributions received during the three preceding taxable years (or during a U.S. Holder’s holding period for the Common Shares, if shorter).

Under Section 1291 of the Code, any gain recognized on the sale or other taxable disposition of Common Shares, and any excess distribution paid on the Common Shares, must be ratably allocated to each day in a Non-Electing U.S. Holder’s holding period for the Common Shares.  The amount of any such gain or excess distribution allocated to prior years of such Non-Electing U.S. Holder’s holding period for the Class Common Shares (other than years prior to the first taxable year of the Company during such Non-Electing U.S. Holder’s holding period and beginning after December 31, 1986 for which we were not a PFIC) will be subject to U.S. federal income tax at the highest tax applicable to ordinary income in each such prior year.  A Non-Electing U.S. Holder will be required to pay interest on the resulting tax liability for each such prior year, calculated as if such tax liability had been due in each such prior year. Such a N on-Electing U.S. Holder that is not a corporation must treat any such interest paid as “personal interest,” which is not deductible.  The amount of any such gain or excess distribution allocated to the current year of such Non-Electing U.S. Holder’s holding period for the Common Shares will be treated as ordinary income in the current year, and no interest charge will be incurred with respect to the resulting tax liability for the current year.

If we are a PFIC for any taxable year during which a Non-Electing U.S. Holder holds Common Shares, we will continue to be treated as a PFIC with respect to such Non-Electing U.S. Holder, regardless of whether we cease to be a PFIC in one or more subsequent years.  A Non-Electing U.S. Holder may terminate this deemed PFIC status by electing to recognize gain (which will be taxed under the rules of Section 1291 of the Code discussed above) as if such Common Shares were sold on the last day of the last taxable year for which the Company was a PFIC.

QEF Election

A U.S. Holder that makes a QEF Election generally will not be subject to the rules of Section 1291 of the Code discussed above. However, a U.S. Holder that makes a QEF Election will be subject to U.S. federal income tax on such U.S. Holder’s pro rata share of (a) the net capital gain of the Company, which will be taxed as long-term capital gain to such U.S. Holder, and (b) and the ordinary earnings of the Company, which will be taxed as ordinary income to such U.S. Holder.  Generally, “net capital gain” is the excess of (a) net long-term capital gain over (b) net short-term capital loss, and “ordinary earnings” are the excess of (a) “earnings and profits” over (b) net capital gain. A U.S. Holder that makes a QEF Election will be subject to U.S. federal income tax on such amounts for each taxable year in which we are a PFIC, regardless of whether such amounts are actually distribut ed to such U.S. Holder by us.  However, a U.S. holder that makes a QEF Election may, subject to certain limitations, elect to defer payment of current U.S. federal income tax on such amounts, subject to an interest charge.  If such U.S. Holder is not a corporation, any such interest paid will be treated as “personal interest,” which is not deductible.  

A U.S. Holder that makes a QEF Election generally also (a) may receive a tax-free distribution from us to the extent that such distribution represents “earnings and profits” of the Company that were previously included in income by the U.S. Holder because of such QEF Election and (b) will adjust such U.S. Holder’s tax basis in the Common Shares to reflect the amount included in income or allowed as a tax-free distribution because of such QEF Election. In addition, a U.S. Holder that makes a QEF Election generally will recognize capital gain or loss on the sale or other taxable disposition of Common Shares.  

The procedure for making a QEF Election, and the U.S. federal income tax consequences of making a QEF Election, will depend on whether such QEF Election is timely.  A QEF Election will be treated as “timely” if such QEF Election is made for the first year in the U.S. Holder’s holding period for the Common Shares in which we were a PFIC.  A U.S. Holder may make a timely QEF Election by filing the appropriate QEF Election documents at the time such U.S. Holder files a U.S. federal income tax return for such first year. However, if we were a PFIC in a prior year, then in addition to filing the QEF Election documents, a U.S. Holder must elect to recognize (a) a gain (which will be taxed under the rules of Section 1291 of the Code discussed above) as if the Common Shares were sold on the qualification date or (b) if we were also a CFC, such U.S. Holder’s pro rata share of the post-1986 “earnings and profits
48; of the Company as of the qualification date.  The “qualification date” is the first day of the first taxable year in which we were a QEF with respect to such U.S. Holder.  The election to recognize such gain or “earnings and profits” can only be made if such U.S. Holder’s holding period for the Common Shares includes the qualification date.  By electing to recognize such gain or “earnings and profits,” such U.S. Holder will be deemed to have made a timely QEF Election.  In addition, under very limited circumstances, a U.S. Holder may make a retroactive QEF Election if such U.S. Holder failed to file the QEF Election documents in a timely manner.  

A QEF Election will apply to the taxable year for which such QEF Election is made and to all subsequent taxable years, unless such QEF Election is invalidated or terminated or the IRS consents to revocation of such QEF Election.  If a U.S. Holder makes a QEF Election and, in a subsequent taxable year, we cease to be a PFIC, the QEF Election will remain in effect (although it will not be applicable) during those taxable years in which we are not a PFIC.  Accordingly, if we become a PFIC in another subsequent taxable year, the QEF Election will be effective and the U.S. Holder will be subject to the QEF rules described above during any such subsequent taxable year in which we qualify as a PFIC.  In addition, the QEF Election will remain in effect (although it will not be applicable) with respect to a U.S. Holder even after such U.S. Holder disposes of all of such U.S. Holder’s direct and indirect interest in the Common Shares.  Acc ordingly, if such U.S. Holder reacquires an interest in the Company, such U.S. Holder will be subject to the QEF rules described above for each taxable year in which we are a PFIC.

Each U.S. Holder should consult its own financial advisor, legal counsel, or accountant regarding the availability of, and procedure for making, a QEF Election.  U.S. Holders should be aware that there can be no assurance that we will satisfy record keeping requirements that apply to a QEF, or that we will supply U.S. Holders with information that such U.S. Holders require to report under the QEF rules, in event that we are a PFIC and a U.S. Holder wishes to make a QEF Election.  

Mark-to-Market Election

A U.S. Holder may make a Mark-to-Market Election only if the Common Shares are marketable stock. The Common Shares generally will be “marketable stock” if the Common Shares are regularly traded on (a) a national securities exchange that is registered with the Securities and Exchange Commission, (b) the national market system established pursuant to section 11A of the Securities and Exchange Act of 1934, or (c) a foreign securities exchange that is regulated or supervised by a governmental authority of the country in which the market is located, provided that (i) such foreign exchange has trading volume, listing, financial disclosure, and other requirements and the laws of the country in which such foreign exchange is located, together with the rules of such foreign exchange, ensure that such requirements are actually enforced and (ii) the rules of such foreign exchange ensure active trading of listed stocks.

A U.S. Holder that makes a Mark-to-Market Election generally will not be subject to the rules of Section 1291 of the Code discussed above.  However, if a U.S. Holder makes a Mark-to-Market Election after the beginning of such U.S. Holder’s holding period for the Common Shares and such U.S. Holder has not made a timely QEF Election, the rules of Section 1291 of the Code discussed above will apply to certain dispositions of, and distributions on, the Common Shares.  

A U.S. Holder that makes a Mark-to-Market Election will include in ordinary income, for each taxable year in which we are a PFIC, an amount equal to the excess, if any, of (a) the fair market value of the Common Shares as of the close of such taxable year over (b) such U.S. Holder’s tax basis in such Common Shares.  A U.S. Holder that makes a Mark-to-Market Election will be allowed a deduction in an amount equal to the lesser of (a) the excess, if any, of (i) such U.S. Holder’s adjusted tax basis in the Common Shares over (ii) the fair market value of such Common Shares as of the close of such taxable year or (b) the excess, if any, of (i) the amount included in ordinary income because of such Mark-to-Market Election for prior taxable years over (ii) the amount allowed as a deduction because of such Mark-to-Market Election for prior taxable years.  

A U.S. Holder that makes a Mark-to-Market Election generally also will adjust such U.S. Holder’s tax basis in the Common Shares to reflect the amount included in gross income or allowed as a deduction because of such Mark-to-Market Election.  In addition, upon a sale or other taxable disposition of Common Shares, a U.S. Holder that makes a Mark-to-Market Election will recognize ordinary income or loss (not to exceed the excess, if any, of (a) the amount included in ordinary income because of such Mark-to-Market Election for prior taxable years over (b) the amount allowed as a deduction because of such Mark-to-Market Election for prior taxable years).

A Mark-to-Market Election applies to the taxable year in which such Mark-to-Market Election is made and to each subsequent taxable year, unless the Common Shares cease to be “marketable stock” or the IRS consents to revocation of such election.  Each U.S. Holder should consult its own financial advisor, legal counsel, or accountant regarding the availability of, and procedure for making, a Mark-to-Market Election.

Other PFIC Rules

Under Section 1291(f) of the Code, the IRS has issued proposed Treasury Regulations that, subject to certain exceptions, would cause a U.S. Holder that had not made a timely QEF Election to recognize gain (but not loss) upon certain transfers of Common Shares that would otherwise be tax-deferred (e.g., gifts and exchanges pursuant to corporate reorganizations).  However, the specific U.S. federal income tax consequences to a U.S. Holder may vary based on the manner in which Common Shares are transferred.  

Certain additional adverse rules will apply with respect to a U.S. Holder if we are a PFIC, regardless of whether such U.S. Holder makes a QEF Election.  For example under Section 1298(b)(6) of the Code, a U.S. Holder that uses Common Shares as security for a loan will, except as may be provided in Treasury Regulations, be treated as having made a taxable disposition of such Common Shares.  

The PFIC rules are complex, and each U.S. Holder should consult its own financial advisor, legal counsel, or accountant regarding the PFIC rules and how the PFIC rules may affect the U.S. federal income tax consequences of the acquisition, ownership, and disposition of Common Shares.

This summary is of a general nature only and is not intended to be relied on as legal or tax advice or representations to any particular investor.  Consequently, potential investors are urged to seek independent tax advice in respect of the consequences to them of the acquisition of common stock having regard to their particular circumstances.

ITEM 11 – QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

We are exposed to financial market risks, credit risks on investments and foreign currency exchange rates.  We do not use derivative financial instruments.  

Financial Market and Credit Risk

At March 31, 2007 we had invested approximately $3.3 million (March 31, 2006: $1.8 million) in short-term marketable securities.  A fundamental objective of our investment policy is to obtain better than bank interest return on the surplus funds being held while we review and finalize opportunities for participation in oil and gas projects. Our investments are mostly in marketable securities quoted and traded on Canadian or US exchanges. We have consultants with extensive experience monitoring our investments on a daily basis and therefore believe that we will be able to respond on time to any major factors affecting the value of our investments and reduce or eliminate the risks of significant market price fluctuations. Further discussion of our investment strategy is set forth in item 3D under the heading “Our short term investments are susceptible to market fluctuations and other risks”.

Foreign Currency Risk

We operate internationally, however the majority of our expenditures are in Canadian or United States dollars. As at March 31, 2007; approximately $5 million – 75% -  of our assets were held in US dollar.  (As at March 31, 2006: $3.1 million or 57%).  We incurred a foreign exchange loss of $111,659 for the year ended March 31, 2007 (see “ITEM 5, OPERATING AND FINANCIAL REVIEW AND PROSPECTS – OPERATING RESULTS - Other Income and Expenses”).   Due to our net United States dollar working capital position in Fiscal 2007 and the increasing value of the Canadian dollar as compared to the United States dollar, we incurred a foreign exchange loss.

Further, the Company also plans activities in different countries involving different local currencies. Exchange rates for these currencies in the future may have an adverse effect on our earnings or assets when these currencies are exchanged for Canadian dollars.  The Company has not entered into forward foreign exchange contracts in an attempt to mitigate this risk.  To date, losses and gains resulting from foreign exchange transactions have been included in our results of operations.  Further discussion of foreign currency risk is set forth in Item 3 D under the heading, “Conducting business in foreign countries.”

The Company has no debt instruments subject to interest payments, sales contracts, swaps, derivatives, or forward agreements or contracts, or inventory.

The Company has no currency or commodity contracts, and the Company does not trade in such instruments.

The Company periodically accesses the capital markets with the issuance of new shares to fund operating expenses and new projects.

ITEM 12 – DESCRIPTION OF SECURITIES OTHER THAN EQUITY SECURITIES

Not applicable.

PART II

ITEM 13 – DEFAULTS, DIVIDEND ARREARAGES AND DELINQUENCIES

None.

ITEM 14 – MATERIAL MODIFICATIONS TO THE RIGHTS OF SECURITY HOLDERS AND USE OF PROCEEDS

No modifications or qualifications have been made in the Fiscal Year to the instruments defining the rights of the holders of our Common Shares and no material amount of assets securing our securities has been withdrawn or substituted by us or anyone else (other than in the ordinary course of business).

ITEM 15  - CONTROLS AND PROCEDURES

a) Disclosure controls and procedures

We have no employees. Our Chief Executive Officer who also serves as Chief Financial Officer (“CEO”) is primarily responsible in establishing and maintaining controls and procedures concerning disclosure of material information and their timely reporting in consultation and under direct supervision of the audit committee which comprises two independent directors. We therefore do not have an effective internal controls and procedures due to lack of segregation of duties. However, given the size and nature of our current operations and involvement of independent directors in the process significantly reduce the risk factors associated with the lack of segregation of duties.

The CEO has instituted a system of disclosure controls for the Corporation to ensure proper and complete disclosure of material information. The limited number of consultants and direct involvement of the CEO facilitates access to real time information about developments in the business for drafting disclosure documents. All documents are circulated to the board of directors and audit committee according to the disclosure time-lines.

In July 2006 a comprehensive review of risk factors facing the Corporation was undertaken by management and the board of directors. Mitigating controls and procedures were identified wherever possible. New procedures were implemented in a couple of cases where it was evident that controls were not robust enough to ensure appropriate disclosure in a timely manner. Some controls were implemented as a secondary detection mechanism if the initial controls failed to prevent errors from occurring.

The CEO, after evaluating the effectiveness of the Corporation’s disclosure controls and procedures (as defined in U.S. Exchange Act Rule 13a-14(c)) as of the end of the period covered by this Form 20-F, have concluded that, as of such date, the Corporation’s disclosure controls and procedures were effective to ensure that material information relating to the Corporation was made known to him by others within the Corporation during the period in which this Form 20-F was being prepared.

There were no significant changes in the Corporation's internal controls or in other factors that could significantly affect these controls subsequent to the date the CEO completed his evaluation, nor were there any significant deficiencies or material weaknesses in the Corporation's internal controls requiring corrective actions other than the lack of segregation of duties.

b) Management’s annual report on internal control over financial reporting

Not applicable, pursuant to temporary rules of the Securities and Exchange Commission.

c) Attestation report of the registered public accounting firm

Not applicable, pursuant to temporary rules of the Securities and Exchange Commission.

ITEM 16   (A)   AUDIT COMMITTEE FINANCIAL EXPERTS

Mr. Bradley’s background is described under Item 6(A) Directors and senior management.

Effective December 8, 2006, Mr. Damian Lee was replaced by Mr. Brett Rees as independent director and a member of the audit committee. Mr. Dean Bradley continues as a financial expert.

ITEM 16 (B)   CODE OF ETHICS

AUDITORS’ REPORT

To the Shareholders of

Bontan Corporation Inc.

We have audited the consolidated balance sheets of Bontan Corporation Inc. as at March 31, 2007 and 2006 and the related consolidated statements of operations, shareholders' equity and cash flows for the years then ended. These consolidated financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these consolidated financial statements based on our audit.

We conducted our audit in accordance with Canadian generally accepted auditing standards and with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform an audit to obtain reasonable assurance whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation.

SIGNIFICANT ACCOUNTING POLICIES (Continued)

Mineral Properties (discontinued operation)

The cost of each mineral property or interest therein, together with exploration costs are capitalized until the properties to which they relate are placed into production, sold or abandoned. These costs will be amortized on the basis of units produced in relation to the proven reserves available on the related property following commencement of production. Costs of abandoned properties are written off to operations.

The costs capitalized do not necessarily reflect present or future values. The ultimate recovery of such amounts depends on the discovery of economically recoverable reserves, successful commercial development of the related properties, availability of financing and future profitable production or proceeds from the disposition of the properties.

Although the Company has taken steps to verify the title to resource properties in which it has an interest, in accordance with industry standards for the current stage of exploration of such properties, these procedures do not guarantee the Company’s title. Property title may be subject to unregistered prior agreements, transfers or aboriginal land claims and title may be affected by undetected defects.

The company discontinued its mineral exploration activities effective December 30, 2004.

Oil and Gas Properties Interest

Interests held in oil and gas properties are recorded on the basis of successful efforts method of accounting for oil and gas exploration and development activities under which direct acquisition costs of development properties, geological and geophysical costs associated with these properties and costs of development and exploratory wells that result in additions to proven reserves are capitalized. When the carrying value of a property exceeds its net recoverable amount that may be estimated by quantifiable evidence of an economic geological resource or reserve, joint venture expenditure commitments or the Company’s assessment of its ability to sell the property for an amount exceeding the deferred costs, provision is made for the impairment in value.

Revenue Recognition

Revenues associated with the sales of natural gas, crude oil and natural gas liquids (“NGLs”) together with costs including production and mineral taxes, royalty to landowner and transportation and selling costs are recognized on receipt of a statement of account from the operators of the projects where the Company holds equity interest and collection is reasonably assured.

Short-term Investments

Short-term investments are investments that are either highly liquid or are to be disposed of within a one year period and are recorded at lower of cost and market value. All short term investments are considered available for sale type of investments.

Foreign Currency Translation

The functional currency of the Company is the Canadian dollar. Monetary assets and liabilities are translated at exchange rates in effect at the balance sheet date.  Non-monetary assets are translated at exchange rates in effect when they were acquired. Revenue and expenses are translated at the approximate average rate of exchange for the year, except that amortization is translated at the rates used to translate related assets. The resulting gains or losses on translation are included in the consolidated statement of operations.

SIGNIFICANT ACCOUNTING POLICIES (Continued)

Future Income Taxes

The Company follows the asset and liability method of accounting for income taxes.  Under this method, future income tax assets and liabilities are determined based on temporary differences between financial reporting and tax bases of assets and liabilities, as well as for the benefit of losses available to be carried forward to future years for tax purposes.  Future income tax assets and liabilities are measured using substantively enacted tax rates and laws that will be in effect when the differences are expected to reverse.  Future income tax assets are recognized in the financial statements if realization is considered more likely than not. A valuation allowance against future tax assets is provided to the extent that the realization of these future tax assets is not more likely than not.

Stock-Based Compensation Plan

The Company follows a fair value based method of accounting for all Stock-based Compensation and Other Stock-based Payments to employees and non-employees.  The fair value of all share purchase options is expensed over their vesting period with a corresponding increase to contributed surplus. Upon exercise of share purchase options, the consideration paid by the option holder, together with the amount previously recognized in contributed surplus, is recorded as an increase to share capital. The Company uses the Black-Scholes option valuation model to calculate the fair value of share purchase options at the date of grant.

The market value of the Company’s share on the date of issuance of shares under any stock compensation plan is considered as fair value of the shares issued.

Loss Per Share

Basic loss per share is calculated by dividing net loss (the numerator) by the weighted average number of common shares outstanding (the denominator) during the period.  Diluted loss per share reflects the dilution that would occur if outstanding stock options and share purchase warrants were exercised or converted into common shares using the treasury stock method and are calculated by dividing net loss applicable to common shares by the sum of the weighted average number of common shares outstanding and all additional common shares that would have been outstanding if potentially dilutive common shares had been issued.

The inclusion of the Company’s stock options and share purchase warrants in the computation of diluted loss per share would have an anti-dilutive effect on loss per share and are therefore excluded from the computation.  Consequently, there is no difference between basic loss per share and diluted loss per share.

Use of estimates

The preparation of financial statements in conformity with Canadian generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the period.  Actual results could differ from those estimates.  Some of the key areas where estimates and assumptions are normally used include valuation of stocks, warrants and options.

SHORT TERM INVESTMENTS

Short-term investments are comprised of marketable securities.  The quoted market value of the securities on hand as at March 31, 2007 was $ 4,275,393 (2006: $ 2,524,849) resulting in an unrealised gain of $959,701 (2006: $746,928), which has not been accounted for according to the stated accounting policy.

Included in the short-term investments are 100,000 shares (2006: nil) of a US public corporation subscribed under private placements at a total cost of US$ 100,000 (2006: nil) (market value at March 31, 2007:  US$164,000).  These shares cannot be traded until their registration with the US Securities and Exchange Commission according to the restrictive conditions of the private placement.

Also included in the short-term investments is 500,000 Common shares (2006: nil) in a private corporation for a cost of US$50,000 (2006: nil) and 50,000 preference shares (2006: 50,000 preference shares) held in another private corporation for a cost of US$50,000 (2006: US$50,000). The market value of these shares as at March 31, 2007 was not available but management believes that this approximates the cost.  However, based on the management review of the affairs of the investee companies and discussions with their management, it was concluded that there was no permanent impairment in the carrying costs of these investments.

i. Interest in oil properties (applicable to fiscal year 2006):

On July 5, 2005, the Company sold its 0.75% Indirect Participation Interest in an oil exploration project in Papua New Guinea (IPI Interest) for a sum of US$3.2 million to an independent institutional investor under an IPI purchase agreement dated July 5, 2005.  The Company received the funds on July 7, 2005. Under the agreement, the Company will no longer be responsible for any future cash calls and other obligations of the Project.

The Company paid cash fee of US$32,000 plus 16,000 restricted common shares of the Company valued at US$16,000 to an independent US brokerage firm, which introduced the buyer.

In addition, the Company also granted, on December 5, 2005, 1.1 million options to acquire equal number of common shares of the Company to Mr. Terence Robinson exercisable at US$0.50 per option, for successfully bringing in and negotiating the deal. The value of the option granted of $655,779 based on Black-Scholes option price model was charged against the proceeds of the sale of IPI interest.

OIL AND GAS PROPERTIES INTERESTS - Continued….

ii. Interest in gas properties

On October 15, 2004, the Company entered into an exploration agreement with a private investors group in the United States under which it acquired 49% gross working interest in a gas exploration project in the State of Louisiana, USA (the project).

By September 20, 2005, the Company paid approximately US$3.5 million towards seismic survey, land leases and exploration costs of the first exploration test well under the project.

The drilling began on August 21, 2005 and the targeted depth of 15,378’ was reached on October 19, 2005.

On October 21, 2005, the Company was informed by the project operators that based on electric log analysis and wireline formation tests results, the well could not be completed as a well capable of commercial production and therefore the well should be plugged and abandoned and all leases be allowed to expire.

Consequently, the management decided to write off the carrying value of the interest in the gas project in October 2005.

In July 2006, the company paid $4,142 (US$3,638) to the project contractor towards its share of the cost of open hole logging. The Company does not expect any further costs on this project.

On February 24, 2006, the Company reached an agreement with certain accredited investors for a private placement of 10.4 million Units at US$0.25 per Unit for gross proceeds of US$2.6 million. Each Unit includes one common share and one common share purchase warrant. Each warrant entitles its holder to acquire one common share of the company at a price of US$0.35 within twenty-four months of the date of issuance of the Unit.  Private placement was closed on April 16, 2006. The number of Units subscribed under the private placement between April 1, 2006 and the closing date was 4.5 million resulting in issuance of equal number of common shares.

The 10.4 million shares issued under this private placement were registered with the US Securities and Exchange Commission on November 30, 2006 and are therefore freely tradable.

WARRANTS – Continued…….

(i)

The company issued 6.5 million warrants (2006: 3.9 million warrants) under a 2006 private placement. 2 million warrants relating to Units subscribed and paid for prior to March 31, 2006 and the balance of 4.5 million relating to Units subscribed during the current period as explained in Note 6(b)(i). These warrants are convertible into equal number of common shares at an exercise price of US$0.35 per warrant and expiry within two years of their issue.

The fair value of these warrants has been estimated using a Black-Scholes option price model with the following assumptions:

Risk free interest rate

5%

Expected dividend

nil

Expected volatility

130%

Expected life

730 days

Market price

US$0.67

The amount of $3,810,814 has been accounted for as a reduction of the value of the shares issued.

(ii)

On April 16, 2006, the Company issued 1,040,000 warrants to Current Capital Corp., a related party as part of the finder’s fee in connection with a private placement as explained in Note 6(b)(ii). The warrants are convertible into equal number of common shares at an exercise price of US$0.35 per warrant and expiry within two years of their issue.

The fair value of these warrants has been estimated using a Black-Scholes option price model with the assumptions detailed in 8(i) above. The amount of $609,730 has been accounted for as a finder’s fee.

The shares issuable upon exercise of these warrants were registered with the US Securities and Exchange Commission on November 30, 2006 and will therefore be freely tradable when issued.

iii)

1,721,960 warrants issued under 2003 private placement were originally expiring on March 31, 2007. The board extended the expiry date on March 30, 2007 to March 31, 2009.  

The fair value of these warrants as of March 31, 2007, being the date on which their terms changed,  has been estimated using a Black-Scholes option price model with the following assumptions:

Risk free interest rate

5%

Expected dividend

nil

Expected volatility

52.25%

Expected life

731 days

Market price

US$0.30

Exercise price

US$1.00

The amount of $20,846 resulting from the above criteria was considered immaterial and no revision was made to the existing value of the warrants for extending their expiry date.

WARRANTS – Continued…….

Option price models used for calculating fair value of warrants require input of highly subjective assumptions including the expected price volatility. Changes in the subjective input assumptions can materially affect the fair value estimate, and therefore the models do not necessarily provide a reliable measure of the fair value of the Company’s warrants.

9.

LOSS PER SHARE

Loss per share is calculated on the weighted average number of common shares outstanding during the year, which were 27,472,703 shares for the year ended March 31, 2007 (2006 – 15,655,023, 2005 – 11,700,303).

The Company had approximately 13.1 million warrants and 4.8 million options, which were not exercised as at March 31, 2007. Inclusion of these warrants and options in the computation of diluted loss per share would have an anti-dilutive effect on loss per share and are therefore excluded from the computation. Consequently, there is no difference between loss per share and diluted loss per share.

10. DISCONTINUED OPERATIONS

On December 30, 2004, the Company decided to close its operations in Brazil and discontinue further participation in any diamond mining activities. It had only one existing joint venture which was dissolved due to the failure of the local partner to obtain the environmental permit for exploratory drilling, which was a pre-condition to the Company’s commitment to invest more money into the program. The Company also had option to acquire mining rights in another program. The option expired on December 31, 2004 and was not renewed.

SEGMENTED INFORMATION

As at March 31, 2007 and 2006, the Company had only one major business segment-

Energy sector: This segment includes the Company’s acquisition of interests in joint ventures and projects relating to exploration and commercial drilling of oil and gas and related products.

The Company discontinued its mineral activities effective December 30, 2004.

The accounting policies of the segments are same as those described in Note 2. The Company evaluates each segment’s performance based on its contribution to consolidated net earnings. There are no inter-segmental charges or transactions. The following table presents summarised financial information for the fiscal years ended March 31, 2007 and 2006

Geographic Information

The Company operates from one location in Canada. Its assets are located as follows:

	2007	2006
Canada	$6,557,628	$5,432,531
USA	115,290	18,241
	$6,672,918	$5,450,772

15.

FINANCIAL INSTRUMENTS AND CONCENTRATION OF RISKS

The fair value for all financial assets and liabilities are considered to approximate their carrying values due to their short-term nature.

There is an exposure to market price fluctuation risk on the Company’s short term investments in marketable securities which accounted for approximately 50% of total assets of the Company as at March 31, 2007. Further, the Company’s holding in one Canadian marketable security accounted for approximately 50% of the total short term investment in marketable securities or 24% of total assets at March 31, 2007. The management mitigates this risk by daily monitoring of all its investments by experienced consultants.

The Company also has a currency exposure on its US dollar cash balances on hand at March 31, 2007, which accounted for approximately 12% of the total assets.

DIFFERENCES BETWEEN CANADIAN AND UNITED STATES GENERALLY ACCEPTED ACCOUNTING PRINCIPLES (Continued)

The impact of the above differences between Canadian GAAP and US GAAP on the consolidated statements of cash flows would be as follows:

Year ended March 31	2007	2006	2005
Cashflows used in continuing operating activities, Canadian GAAP	$ (533,465)	$ (752,520)	$ (854,783)
Adjustment to oil & gas properties interests (ii)	-	-	(216,568)
Cashflows used in  operating activities,  US GAAP	(533,465)	(752,520)	(1,071,351)
Cashflows provided by (used) in investing activities, Canadian GAAP	(887,262)	(699,685)	476,319
Adjustment to oil & gas properties interests (ii)	-	-	216,568
Cashflow provided by (used) in investing activities	(887,262)	(699,685)	692,887
Cashflow provided by financing activities, Canadian and US GAAP	1,172,813	3,854,717	738,253
Increase(decrease) in cash during period, Canadian and US GAAP	(247,914)	2,402,512	359,789
Cash at beginning of year	3,262,842	860,330	500,541
Cash at end of year	$ 3,014,928	$ 3,262,842	$  860,330

The following are brief explanations of the identified differences:

(i)

Short-term Marketable securities

In accordance with Canadian GAAP, short-term marketable securities are carried at the lower of aggregate cost and current market values, with unrealized losses being included in the determination of net income (loss) for the year. Statement of Financial Accounting Standard (“SFAS”) No. 115, “Accounting for Certain Investments in Debt and Equity Securities”, requires that equity securities that have readily determinable fair values be classified as either available-for-sale or trading securities, and that they be reported at fair market values. For available-for-sale securities, unrealized gains or losses are to be reported as other comprehensive income, a separate component of shareholders’ equity, until realized. All our short term investments are classified as “available for trade” and the resultant unrealised gains for the year are included as other comprehensive income in the reconciliation.

(ii)

Oil and gas properties interests

Under Canadian GAAP, mineral properties, including exploration, development and acquisition costs, are carried at cost until the properties to which they relate are placed into production, sold or where management has determined there to be a permanent impairment in value.

Under U.S. GAAP, mineral property expenditures are expensed as incurred. Once a final feasibility study has been completed however, additional costs incurred to bring the mine into production are capitalized as development costs.

Fiscal 2005

As the Company’s interests in gas project is currently at exploratory stages as explained in Note 5, it has been decided to expense the cost of acquiring the interests and its contribution to exploration costs under the US GAAP. No adjustment is considered necessary as regards the Company’s interest in oil properties since the interest was subsequently sold at a profit and was therefore not considered held for exploration as at March 31, 2005.

Similarly, the costs for the year were treated as part of cash flows from operating activities instead of investing activities under the US GAAP.

(iii)

Exchange gains and losses on translation of foreign currency items and balances

Under Canadian GAAP, gains or losses arising from the translation of foreign currency financials into the reporting currency, which is Canadian dollar, are included in the computation of net income.

Under FAS 52 (13) and FAS 130, translation adjustments resulting from translating foreign currency financials into the reporting currency shall not be included in determination of net income but shall be included in other comprehensive income computation.

Translation losses arising from translating the foreign currency financials, into Canadian dollar at the year end were therefore eliminated from the computation of net income and included in the computation of the comprehensive income in the reconciliation.

Recently issued accounting standards

The following standards were issued by the Financial accounting Standards Board during 2007 and 2006:

In May 2005, the FASB issued SFAS Statement No. 154, Accounting Changes and Error Corrections (“SFAS 154”). SFAS 154 is a replacement of Accounting Principles Board Opinion No. 20 (“APB 20”) and FASB Statement No. 3. SFAS 154 provides guidance on the accounting for and reporting of accounting changes and error corrections. It establishes retrospective application, or the latest practicable date, as the required method for reporting a change in accounting principle and the reporting of a correction of an error. SFAS 154 is effective for accounting changes and corrections of errors made in fiscal years beginning after December 15, 2005. The adoption of SFAS 154 did not have a material impact on our consolidated financial position, results of operations or cash flows.

DIFFERENCES BETWEEN CANADIAN AND UNITED STATES GENERALLY ACCEPTED ACCOUNTING PRINCIPLES – Recent Pronouncements - Continued

In June 2005, the FASB issued Staff Position Paper (“FSP”) 115-1, The Meaning of Other-Than-Temporary Impairment and its Application to Certain Investments, superseding EITF 03-1. FSP 115-1 will replace the accounting guidance on the determination of whether an investment is other-than-temporarily impaired as set forth in EITF 03-1 with references to existing other-than-temporary impairment guidance. FSP 115-1 is effective for reporting periods beginning after December 15, 2005. Adoption of FSP 115-1 did not have a material impact on our consolidated financial position, results of operations or cash flows.

 

In February 2006, FASB issued SFAS No. 155, “Accounting for Certain Hybrid Financial Instruments – an Amendment of FASB Statements No. 133 and 140”. Among other things, SFAS No. 155 permits the election of fair value remeasurement for certain hybrid financial instruments that would otherwise require bifurcation under Statement 133, Accounting for Derivative Instruments and Hedging Activities. These hybrid financial instruments would include both assets and liabilities. SFAS No. 155 is effective for fiscal years beginning after September 15, 2006.

The Company has not yet determined the effect of future implementation of this new standard on its financial statements.

In March 2006, the FASB issued SFAS No. 156, “Accounting for Servicing of Financial Assets” (“SFAS 156”). SFAS 156 addresses the accounting for recognized servicing assets and servicing liabilities related to certain transfers of the servicer’s financial assets and for acquisitions or assumptions of obligations to service financial assets that do not relate to the financial assets of the servicer and its related parties. SFAS 156 requires that all recognized servicing assets and servicing liabilities are initially measured at fair value, and subsequently measured at either fair value or by applying an amortization method for each class of recognized servicing assets and servicing liabilities. SFAS 156 is effective in fiscal years beginning after September 15, 2006. The adoption of SFAS 156 is not expected to have a material impact on our consolidated financial statements.

In July 2006, FASB issued FIN 48 “Accounting for Uncertainty in Income Taxes – an Interpretation of FASB Statement No. 109” FIN 48 seeks to reduce the significant diversity in practice associated with financial statement recognition and measurement in accounting for income taxes. FIN 48 is effective in fiscal years beginning after December 15, 2006.

 

The Company has not yet determined the effect of future implementation of this new interpretation on its financial statements.

In September 2006, FASB issued Standard 157 ‘Fair Value Measurements’. FAS 157 provides enhanced guidance for using fair values to measure assets and liabilities and applies whenever other standards require (or permit) assets or liabilities to be measured at fair value. FAS157 does not expand the use of fair values in any new circumstances. FAS157 is effective for fiscal years beginning after November 15, 2007.

The Company has not yet determined the effect of future implementation of this new standard on its financial statements.

DIFFERENCES BETWEEN CANADIAN AND UNITED STATES GENERALLY ACCEPTED ACCOUNTING PRINCIPLES – Recent Pronouncements - Continued

In September 2006, FASB issued Statement No. 158, Employers’ Accounting for Defined Benefit Pension and Other Postretirement Plans - an amendment of FASB Statements No. 87, 88, 106, and 132(R).  This Statement applies to employers that sponsor single-employer defined benefit pension and other postretirement plans

The requirement to recognize the funded status of a benefit plan and the disclosure requirements for entities with publicly traded equity securities are effective as of the end of the fiscal year ending after December 15, 2006

The Company currently does not have any defined benefit plan or any other post retirement plans. The Company will therefore determine the effect of future implementation of these new FAS, if and when it introduces any post retirement plans.

In September 2006, the Securities and Exchange Commission released SAB No. 108 regarding the effects of prior year misstatements in considering current year misstatements for the purpose of a materiality assessment. The opinion in SAB 108 is that in the case of an error that has occurred and been immaterial in a number of previous years, the cumulative effect should be considered in assessing the materiality of the error in the current year. If the cumulative effect of the error is material, then the current year statements, as well as prior year statements should be restated. In the case of restated prior year statements, previously filed reports do not need to be amended, if the error was considered immaterial to previous year’s financial statements. However the statements should be amended the next time they are filed. The effects of this guidance should be applied cumulatively to fiscal years ending March 31, 2007 onwards. Additional disclosure should be made regarding any cumulative adjustments made in the current year financial statements. Adoption of this SAB did not have any significant impact on the Company’s consolidated financial statements.

In February 2007, the FASB issued SFAS Statement No. 159, the Fair Value Option for Financial Assets and Financial Liabilities – Including an amendment of SFAS No. 115. This Statement permits entities to choose to measure many financial instruments and certain other items at fair value. This Statement is effective as of the beginning of an entity’s first fiscal year that begins after November 15, 2007.

The Company will implement this standard on the effective date especially with regards to its available for sale investments.
