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 Internet and high technology industry,

- - 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. We cannot assure you that the actual results or developments anticipated by us will be realized or, even if substantially realized, that they will have the expected effect on us or our business or operations.

Unless the context indicates otherwise, the terms "Bontan Corporation Inc." the "Company" and "Bontan" are used interchangeably in this Annual Report.

FOREIGN PRIVATE ISSUER STATUS AND CURRENCIES AND EXCHANGE RATES

Foreign Private Issuer Status:

Bontan Corporation Inc., (the "Company"), is a Canadian corporation incorporated under the laws of the Province of Ontario. Approx. 84% of its common stock is held by non-United States citizens and residents; our business is administered principally outside the United States; and all of our assets are located 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.

Currency

The financial information presented in this Annual Report is expressed in Canadian dollars ("CDN $") and the financial data in this Annual Report is presented in accordance with accounting principles generally accepted in Canada ("Can. GAAP"). Such financial data conforms in all material respects with accounting principles generally accepted in the United States ("U.S. GAAP") except as disclosed in Note 14 of the Notes to Consolidated Financial Statements contained herein.

All dollar amounts set forth in this report are in Canadian dollars, except where otherwise indicated.

1. The effect of potential share issuances pursuant to the exercise of options and warrants would be anti-dilutive and, therefore, basic and diluted losses per share are the same. The net loss per share prior to fiscal 2004 was based on the pre-reverse split number of shares issued and outstanding.

2. Weighted average number of shares for a year was calculated by dividing the total of the number of shares outstanding at the end of each of the months by twelve.

3. Decrease in the weighted average number of shares outstanding in fiscal 2004 compared to 2003 was due to a reverse stock split of 7 to 1 in fiscal 2004.

(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.

Exploration and Development Risks

The Company plans to engage in the business of acquiring interests in resource properties in the hope of locating reserves. The Company's property interests will 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. 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 has 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 additional crude oil or natural gas in commercial quantities will be discovered by the Company.

Additional Funding Requirements

The Company has not received cash flow from operations in the past and cash flow is not expected in the next few years to satisfy the Company’s operational requirements and cash commitments. In the past, the Company has relied on borrowings from the shareholders and sales of equity securities to meet most of its cash requirements. There can be no assurance that funding from these sources will be sufficient in the future to satisfy operational requirements and cash commitments. Accordingly, there is substantial doubt about the Company’s ability to continue as a going concern.

Based on its existing working capital, the Company expects to require additional financing for its currently committed interests in resource properties during the upcoming fiscal year. The development of the Company’s properties depends upon the Company’s ability to obtain financing through any or all of the joint venturing of projects, debt financing, equity financing or other means. There is no assurance that the Company will be successful in obtaining the required financing. Failure to obtain additional financing on a timely basis could cause the Company to forfeit its interest in its properties and reduce or terminate its operations on such properties.

History of Net Losses; Accumulated Deficit; Lack of Revenue From Operations

The Company has incurred net losses to date. Its deficit as of March 31, 2004, was approx. $22 million. The Company has not yet had any revenue from the exploration activities on its properties, nor has the Company yet found that development activity is warranted on any of its properties. Even if the Company does undertake development activity on any of its properties, the Company may continue to incur losses beyond the period of commencement of such activity. There is no certainty that the Company will produce revenue, operate profitably or provide a return on investment in the future.

Stock 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 prices, (d) contains a toll-free telephone number for inquiries on disciplinary histories of brokers and dealers, and (e) defines 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.

Uninsurable Risks

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. The Company and its subsidiaries intend to engage in participating in the drilling of both exploratory and development wells. Exploratory wells have much greater dry hole risk than do wells, which are drilled offsetting established production. The Company and its subsidiaries may become subject to liability for pollution, fire, explosion, blow-outs, cratering and oil spills against which it cannot insure or against which it may elect not to insure. Such events could result in substantial damage to oil and gas wells, producing facilities and other property and personal injury. The payment of any such liabilities may have a material, adverse effect on the Company's financial position.

Foreign Countries and Regulatory Requirements

Company’s current business strategy involves 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 precious metal 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.

Environmental and Other Regulatory Requirements

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 oil and gas 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 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.

The Company’s potential diamond production operations and mining activities in Brazil are subject to various federal and provincial laws governing land use, the protection of the environment, prospecting, development, production, exports, taxes, labour standards, occupational health, waste disposal, toxic substances, workplace safety and other matters. Such operations and exploration activities are also subject to substantial regulation under these laws by governmental agencies and may require that the Company obtain permits from various governmental agencies. . There can be no assurance, however, that all permits the Company may require for conduct of operations will be obtainable on reasonable terms or that such laws and regulations would not have a material adverse effect on any mining project the Company might undertake.

Failure to comply with applicable laws, regulations, and permitting requirements may result in enforcement actions there under, 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. Parties engaged in diamond exploration or extraction operations may be required to compensate those suffering loss or damage by reason of such activities and may have civil or criminal fines or penalties imposed for violations of applicable laws or regulations.

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.

Share Price Volatility; Price Fluctuations

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 junior 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. In particular, the per share price of the Company's common stock fluctuated from a low of US$0.50 to a high of US$2.47 during the year ending on the date of this Annual Report. There can be no assurance that these price fluctuations will not continue to occur.

Company's Officers and Directors Resident Outside U.S.; Potential Unenforceability of Civil Liabilities and Judgments

The Company and its officers and all but one of its directors are residents of countries other than the United States, and all 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.

The Company believes that a judgment of a United States court predicated solely upon civil liability under United States securities laws would probably be enforceable in Canada if the United States court in which the judgment was obtained has a basis for jurisdiction in the matter that was recognized by a Canadian court for such purposes. However, there is doubt whether an action could be brought in Canada in the first instance on the basis of liability predicated solely upon such laws.

Dilution

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. 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.

The Company is currently without a source of revenue and will most likely be required to issue additional securities to finance its operation and may also issue substantial additional securities to finance the development of any or all of its projects.

ITEM 4 – INFORMATION ON THE COMPANY

(A) HISTORY AND DEVELOPMENT OF THE COMPANY

Bontan Corporation Inc. (“the Company’) was incorporated under the Business Corporation Act (Ontario) in 1973 and is based in Toronto, Ontario, Canada.

The Company’s registered office is situated at 47 Avenue Road, Suite 200, Toronto, Ontario, Canada M5R 2G3The 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 Company went through several name changes and five major changes in its business activities. Details of these changes were provided in the Registration Statement F-20 dated June 12, 2000 and the annual report F-20 dated September 23, 2003. The significant changes, briefly, were as follows:

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

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.

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.

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.

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.

The management saw no sign of technology sector reviving in the near future and decided to change the business focus to resource industry. The new business strategy was discussed in the annual and special general meeting held in November 2002 and was accepted by the key shareholders of the company who have been providing the funding for its operational needs to date.

Accordingly, on April 21, 2003, the Company changed its name to Bontan Corporation Inc. and commenced a private placement to raise about US$2.8 million net of issue expenses by May 26, 2004 when the private placement was closed. These funds were invested in acquiring interest in oil exploration project in Papua New Guinea and a subsidiary in Brazil to acquire options in joint ventures for diamond exploration projects and also to fund the working capital requirements of the Company and its subsidiaries.

The Company had no significant revenue since April 1, 1996 except in the fiscal year 2001 and incurred significant losses since inception. Accumulated deficit at March 31, 2004 was approx. $22 million.

The Company relies principally on equity financing to fund its projects and expenditures.

The major expenditure during the fiscal year 2004 comprised funds advanced from time to time of approx. $2.5 million to a non-affiliated corporation, Advisory Group for the purpose of acquiring indirect participation interest of approx. 0.88% in phase one of an oil exploration program in Papua New Guinea

(B) BUSINESS OVERVIEW

The Company changed its name to Bontan Corporation Inc. on April 21, 2003 and adopted a new business strategy that is focused on resource sector. The Company plans to be a diversified natural resource company that will operate and invest in major exploration and exploitation projects in countries around the globe through its subsidiaries by acquiring joint venture, indirect and direct participation interests and working interests in those projects.

The management is aware of the greater degree of uncertainty and risks associated with investments in resource sector and is also aware of a lack of any in –house expertise in the resource sector. It has therefore planned to take the following two measures to minimise the overall financial exposure and increase the possibility of success:

Diversification

The Company will not focus only on one segment of the resource sector but plans to diversify its investment in different segments. Currently, it is focused on opportunities in oil, gas and diamond exploration projects. The management believes that the diversification will provide a broader distribution of risk associated with project failures and costs overruns.

The diversification policy will also extend to undertaking projects in different countries rather than focusing only on one country.

Co-ownership

The Company does not plan to undertake any activities all by itself but would rather participate in joint ventures and /or acquire a percentage of direct, indirect or working interests in projects with others who have broader experience and financial abilities to complete the projects more successfully and in timely manner.

The new business strategy is focused on two broad operating segments –

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.

Mineral sector: This segment includes the Company’s acquisition of interests in joint ventures and projects relating to exploration and commercial mining of diamond, gold and other precious metals.

Overview of the fiscal year ended March 31, 2004

The Company had a name change on April 21, 2003 and adopted a new business strategy as explained earlier.

Company’s auditors DMCT LLP resigned on March 5, 2004 and were replaced by Sloan Paskowitz Adelman LLP (SPA) of 7620 Yonge Street, Suite 400, Thornhill, Ontario, Canada L4J 1V9. DMCT decided not to register with the Public Company Accounting Oversight Board (USA), which became the requirement for all SEC reporting public companies effective March 1, 2004. SPA has been accepted by the Canadian Public Accountability Board and the Public Company Accounting Oversight Board (USA) as a registered member.

Most part of the fiscal 2004 was spent in pursuing two objectives, namely to raise fund and to find opportunity for investment in resource sector

Fund raising activity

The Company needed funds to pursue its new business objectives. However, lack of any activities and the then market price of the Company’s shares made it almost impossible to attract new equity fund. The Company therefore carried out a reverse stock split on April 21, 2003 under which one new common share was issued for every seven old common shares. At the same time, the Company dealt with fractional shares arising from the reverse stock split, the Holders of less than sixty-four common shares of Dealcheck.com Inc (previous name of the Company) were not issued any shares of Bontan Corporation Inc. Instead, they were entitled to a payment of $0.21US per common share. As a result, 3,255 common shares of Dealcheck.com Inc. being equal to 465 common shares of Bontan Corporation Inc. valued at $684US ($939CDN) became eligible under the buy-back plan. The Company set up an accrual for this liability. The actual payments made to March 31, 2004 were $212.

The above measures enabled the Company to achieve a better market price and On April 28, 2003, the Company reached an agreement with certain accredited investors for a private placement of up to 7,143,000 (seven million one hundred forty three thousand) Units at US$0.35 per Unit for a gross proceeds of about US$2.5 million. Each Unit included one common share and one common share purchase warrant. Each warrant entitled its holder to acquire one common share of the company at a price of US$1.00 within twenty-four months of the date of issuance of the Unit. The shares issued under this private placement would be restricted in terms of their transferability and saleability in accordance with the relevant regulatory requirements.

7,536,444 Units were subscribed and paid for up to March 31, 2004. Shares relating to 6,705,015 units were issued by that date while the shares relating to the balance of the subscription of 831,429 units were issued subsequent to March 31, 2004.

Expenses relating to the private placement represented finder’s fee of 10% of the subscription.

Private placement was over subscribed to 8,909,571 units and was closed on May 26, 2004.

Project Investment

Indirect participation Interest in oil exploration program in Papua New Guinea

In April 2003, the Company received an opportunity to participate in phase one of an oil exploration program carried out by InterOil Corporation, a non –affiliated public company over 9 million acres of land covered by three licences in Papua New Guinea. The Company opted to acquire approx. 0.88 % indirect participation interest (IPI) through PNG Venture Limited, a subsidiary of InterOil Corporation. The IPI agreement also provided option to the Company to convert its IPI share into the common shares of InterOil Corporation at a valuation of US$17.75 per share.

However, initially, the Company was not able to participate directly due to certain corporate conditions that InterOil was subject to. The Company therefore agreed to participate through another independent corporation, Advisory Group. The Company began lending funds to Advisory Group according to the funding requirement of IPI Agreement. Under the lending arrangement with Advisory Group, the Company’s advances were fully secured by a first charge on the IPI and were fully convertible into such IPI at the option of the Company, once InterOil Corporation’s corporate matters preventing direct participation by the Company were resolved.

By March 31, 2004, the Company advanced funds totalling $2.5 million to Advisory Group and on July 9, 2004, the Company exercised its option and converted its advances as follows:

US$ 270,900 was converted into 15,262 shares of InterOil Corporation and

Overview

The Company began a new business strategy coupled with consolidation of its share capital and a private placement campaign to raise funds to carry out its new strategy in fiscal year 2004.

During the fiscal year 2004, the Company ‘s key activities were the private placement campaign and review of business opportunities, which fall within the new business strategy. The key elements of income and expenses are discussed below in detail.

Two new business segments emerged from the new business strategy during the fiscal 2004 namely, (i) energy sector – which will include the Company’s planned activities in acquiring interests in oil and gas projects and (ii) mineral sector – which will include the Company’s planned initiatives in acquiring interests in projects involving exploration and commercial mining of diamond, gold and other precious metals.

The company’s performance during the fiscal years 2003 and 2002 are discussed by each of the business segments under which the Company was operating during those years. These business segments were no longer relevant for the fiscal year 2004 as explained earlier.

The performance by business segment was as follows:

Incubation: This segment relates to investing mainly in start up companies with Internet and high technology oriented business plans.

This segment did not generate any revenue. There was no major activity in this segment during the fiscal 2003. The net loss sustained by this segment was approx. $0.1 million in fiscal 2003 compared to $ 0.9 million in fiscal 2002.

Commercial web sites and project development: This segment relates to the Company’s investments in wholly owned commercial web sites and projects. The Biochex project, through an Ontario private company where the Company has full ownership equity, was the only project that was being carried over from the fiscal year 2002. The project cost was fully written off in fiscal 2003.

This segment did not generate any revenue in fiscals 2003 and 2002. Net losses from this segment during fiscal 2003 were approx. $ 89,000 compared to losses of $300 in fiscal 2002.

Fulfillment services: This segment provides administration and operational services to investee companies and other entities where the company may choose to invest in the future.

There was no activity in this segment during the fiscal 2003 and it generated no revenue compared to the revenue of $60,000 in fiscal 2002.

Income

The revenue during the fiscal year 2004 results from exchange gains. The Company had significant transactions in US Dollars. It raised about $2.6 million in US Dollars through private placement and invested about $1.9 million dollars in oil exploration project. These transactions constituted over 90% of the transactions during the fiscal year and were converted into Canadian dollar at rates prevailing on the dates of the transactions as per the Company’s accounting policy. The exchange rates between Canadian Dollar and US Dollar fluctuated significantly during the year from CDN$1.47 = US$1 at March 31, 2003 to CDN$1.31=US$1 at March 31, 2004 – almost 11% decline in US dollar value verses Canadian dollar.

Overall revenue of the Company decreased significantly to $15,256 in fiscal 2003 compared to $66,860 in fiscal 2002.

Various sources of income are discussed below.

Operational services income

The company provided no operational services during the fiscal years 2004 and 2003 and had no income from this source.

The company earned $60,000 in fiscal 2002 from providing management services to an Ontario affiliated shareholder corporation. These services comprised lending the services of two of its directors during the fiscal year in the finance and business development areas of the affiliate. The services were charged at the rate of $10,000 per month. The company earned $120,000 from similar services to the same corporation in the fiscal 2001.

The management services agreement was cancelled effective October 1, 2001 which explains only six months revenue in fiscal 2002 compared to full year’s revenue in fiscal 2001.

Other income

The other income totaled $46,958 in the fiscal 2004 compared to $15,256 in fiscal 2003 and $66,860 in fiscal 2002.

The other income in all the three years comprise mainly of exchange gain.

Expenses

The overall analysis of the expenses is as follows:

Year ended March 31	2004	2003	2002

Operating expenses	$1,407,916	$245,788	$1,135,654
Net loss on investment	-	-	263,832

	$1,106,023	$105,555	$504,982

% of operating expenses	0.785575	0.429455	0.444662

Travel, meals and entertainment

Most of these expenses during the fiscal 2004 were incurred by the CEO of the Company, Mr. Terence Robinson in meeting with the prospective investors in connection with private placement campaign and also in pursuing leads provided by various consultants in business prospects, which conform to the new business strategy of the Company.

There were no new initiatives during fiscal 2003. This explains the significantly lower travel and entertainment.

During the fiscal 2002, the management continued to focus more on handling in -house projects and investments on hand than seeking new businesses due to lack of funding and adverse business climate. Hence travel, meals and entertainment costs declined in fiscal 2002 compared with those of fiscal 2001.

Consulting costs

The consulting fee costs have increased significantly during the fiscal 2004 compared to the prior years mainly due to commencement of new business activities, which required expertise of consultants with background in resource sector in selecting and negotiating appropriate projects for the Company. The total costs include the following three major items –

Fees charged by four independent consultants	$638,177
Fees charged by a corporate shareholder, Snapper Inc.	267,894
Fees paid to Chief Executive Officer	112,150
	$1,018,221
% of total consulting fee for fiscal 2004	0.964827

Consulting fees of $638,177 were paid to four independent consultants whose services have been retained to help management review projects in resource sector for potential participation and or acquisitions and to advise and negotiate terms and pricing most beneficial to the Company. The services of these consultants were originally retained for one year and thereafter would be extended only on a need basis. The fees to these consultants were payable entirely in the common shares of the Company registered under the “2001 Consultants’ Stock Compensation Plan” The common shares were valued at US$0.50 per share for this purpose. The price represented the fair market value.

Consulting fee of $267,894 was paid to a corporate shareholder, Snapper Inc. Of this amount, $81,180(US$ 60,000) (2003: $92,682 and 2002: $94,000) was paid under a Consulting Agreement. The services provided included arranging non-interest bearing working capital funds, introduction to business opportunities and public relations. The Company had successfully used the services of this corporation in the past. Originally, the agreement provided for payment of US$10,000 per month. However, the fee was revised down to US$5,000 per month effective April 1, 2002. The balance of $186,714 (US$138,000) represented one-time finders’ fee charged for introduction to two new projects where the Company agreed to participate subsequent to the year-end date.

Consulting fee was paid to chief executive officer under a consulting agreement revised on April 1, 2003 and which provided for a fee of $10,000 per month.

Consulting fee for fiscal 2002 included approx. $250,000 in fees paid to current and past executives and other consultants of the company for services rendered during current and past years.

Promotion costs

There was no major promotional activity during fiscal years 2004 and 2003.

Professional fees

Professional fees in fiscal 2004 were $110,547 compared to $45,339 in fiscal 2003 and $133,152 in fiscal 2002.

Major item in fiscal 2004 consisted of fees of $93,135 for accounting services. Of this, $27,610 was paid to a shareholder corporation, Current Capital Corp. for providing financial and accounting services under an Expense Sharing Agreement dated April 1, 2003 for one year. The agreement was not renewed on expiry. The balance of $65,525 was paid to an executive by issuance of shares under the “2001 Consultants’ Stock Compensation Plan”. The common shares were valued at their fair market value of US$0.50 per share.

Increase in professional fees in the fiscal 2002 was due to payment of $47,820 in common shares of the company to an executive for the services rendered during current and past years. These shares were registered under the Securities Act of 1933 by filing of Form S-8 on March 28, 2002.

Other professional fees comprise legal costs for filing of Form S-8 and audit costs.

Shareholders information

Shareholder information costs comprise investor relations fee, costs of holding annual general meeting of the shareholders and various regulatory filing fees. Total cost for fiscal 2004 was $165,431 compared to $63,657 for fiscal 2003 and $341,377 for fiscal 2002.

Major item of cost was the investor relations fee of $80,314 and media relations fee of $80,314 charged by a shareholder corporation, Current Capital Corp. Which specializes in handing investor relation and media relations work for small –cap public companies. The fees were charged under an Investor relations contract dated April 1, 2003 and Media relation contract dated April 1, 2003. Both the contracts provide for a monthly fee of US$5,000 each.

Fee for fiscal 2003 mainly includes fee of $60,000 for an investor relation services provided by Current Capital Corp. at the fee of $10,000 per month. The fee was only for the first six months period since the said contract was canceled effective October 1, 2002.

Major item is rent, which declined from about $57,000 in 2002 to $6,000 in 2003 and $5,300 in 2004.

The company cancelled its existing lease and vacated its 5,000 sq.ft. leased premises at 65 Queen Street West in Toronto in February 2002 and moved as subtenant to under 300 sq ft of premises at 47 Avenue Road in Toronto without any long term lease commitment.

Another item – fees charged by transfer agents declined from about $13,500 in fiscal 2002 and 2003 to $7,800 in fiscal 2004. The significant reduction was achieved due to change in transfer agent in fiscal 2003.

The above move together with substantial reduction in related office costs helped substantially reduce the overall operating costs and future operating cash requirements.

The company received a Notice of Termination dated February 6, 2003 from the landlord, wherein the landlord claimed rent arrears of $28,924 and current plus next three months rent and damage for the loss of rent for the remaining term of the lease. The management is of the opinion that they have a strong case against the landlord for not paying such rent and penalty and considers the existing provision of approx. $37,000 adequate to cover any liability arising from the lease termination. Besides, no further communication was received from the landlord during the fiscal 2004.

Besides, no further communication was received from the landlord during the fiscal 2004.

Dividend Policy

Since its incorporation, the Company has not declared or paid, and has no present intention to declare or to pay in the foreseeable future, any cash dividends with respect to its Common Shares. Earnings will be retained to finance further growth and development of the business of the Company. However, if the Board of Directors declares dividends, all Common Shares will participate equally in the dividends, and, in the event of liquidation, in the net assets, of the Company.

(B) SIGNIFICANT CHANGES

The following is a summary of significant changes since the date of the financial statements included in this annual report.

On May 17, 2004, Mr. Terence Robinson resigned as a Chairman and CEO of the Company and in his place Mr. Kam Shah, the CFO assume the responsibilities of Chairman and CEO of the Company effective the same date until the next annual general meeting. Further, Mr. Kevin Markland was appointed as a non-executive, independent director to replace Mr. Terence Robinson.

On May 26, 2004 the Company completed its private placement, which commenced on April 28, 2003, to accredited investors for 8,879,571 Units at US$0.35 per Unit.

The Company’s subsidiary, Bontan Diamond Corporation, acquired on June 14, 2004 100% equity in a Brazilian Corporation, Astrogemas Mineraçao Ltda (“AML”). The management of AML has the right to earn back a 40% interest subject to meeting certain agreed performance milestones. AML holds 50 per cent participation rights in two joint ventures to explore for and mine diamonds in the Coromandel region of Minas Gerais state in Brazil.

On July 9, 2004, the Company converted its advances to a non-affiliated corporation for the purpose of acquiring indirect participation interest (IPI) in an oil exploration program in Papua New Guinea into (i) US$270,900 into 15,262 shares of InterOil Corporation according to the terms of the IPI agreement and (ii) the balance of the advances of approx. US$1.6 million in approx. 0.75% IPI. (See further details in Item 4(B) - overview of the fiscal year ended March 31, 2004.)

On July 22, 2004, the Company registered with Securities and Exchange Commission, two new Plans by filing of the registration statement in Form S-8. The two Plans comprise the 2003 Stock Option Plan covering 2.5 million common shares of the Company and 2003 Consultant Stock Compensation Plan covering 1 million common shares of the Company.

EXCHANGE CONTROLS

There are no governmental laws, decrees or regulations in Canada relating to restrictions on the export or import of capital, or affecting the remittance of interest, dividends or other payments to non-resident holders of the Company’s common shares. Any remittances of dividends to United States residents are, however, subject to a 15% withholding tax (5% if the shareholder is a corporation owning at least 10% of the outstanding common shares of the Company) pursuant to Article X of the reciprocal tax treaty between Canada and the United States. See “Item 10 – Additional Information – E. Taxation” below.

Except as provided in the Investment Canada Act (the “Act”), which has provisions which govern the acquisition of a control block of voting shares by non-Canadians of a corporation carrying on a Canadian business, there are no limitations specific to the rights of non-Canadians to hold or vote the common shares of the Company under the laws of Canada or the Province of Ontario or in the charter documents of the Company.

Management of the Company considers that the following general summary fairly describes those provisions of the Act pertinent to an investment in the Company by a person who is not a Canadian resident (a “non-Canadian”).

The Act requires a non-Canadian making an investment which would result in the acquisition of control of the Canadian business to notify the Investment Review Division of Industry Canada, the federal agency created by the Act; or in the case of an acquisition of a Canadian business, the gross value of the assets of which exceeds certain threshold levels or the business activity of which is related to Canada’s cultural heritage of national identity, to file an application for review with the Investment Review Division.

The notification procedure involves a brief statement of information about the investment on a prescribed form, which is required to be filed with Investment Canada by the investor at any time up to 30 days following implementation of the investment. Once the completed notice has been filed, a receipt bearing the certificate date will be issued to the non-Canadian investor. The receipt must advise the investor either that the investment proposal is unconditionally non-reviewable or that the proposal will not be reviewed as long as notice of review is not issued within 21 days of the date certified under the receipt. It is intended that investments requiring only notification will proceed without government intervention unless the investment is in a specific type of business activity related to Canada’s cultural heritage and national identity.

If an investment is reviewable under the Act, an order for review must be issued within 21 days after the certified date on which notice of investment was received. An application for review in the form prescribed is required to be filed with Investment Canada prior to the investment taking place. Once the application has been filed, a receipt will be issued to the applicant, certifying the date on which the application was received. For incomplete applications, a deficiency notice will be sent to the applicant, and if not done within 15 days of receipt of application, the application will be deemed to be complete as of the date it was received. Within 45 days after the complete application has been received, the Minister responsible for the Investment Canada Act must notify the potential investor that the Minister is satisfied that the investment is likely to be of net benefit to Canada. If within such 4 5-day period the Minister is unable to complete the review, the Minister has an additional 30 days to complete the review, unless the applicant agrees to a longer period. Within such additional period, the Minister must advise either that he is satisfied or not satisfied that the investment is likely to be of net benefit to Canada. If the time limits have elapsed, the Minister will be deemed to be satisfied that the investment is likely to be of net benefit to Canada. The investment may not be implemented until the review has been completed and the Minister is satisfied that the investment is likely to be of net benefit to Canada.

If the Minister is not satisfied that the investment is likely to be of net benefit to Canada, the non-Canadian must not implement the investment or, if the investment has been implemented, could be penalized by being required to divest himself of control of the business that is the subject of the investment. To date, the only types of business activities which have been prescribed by regulation as related to Canada’s cultural heritage or national identity deal largely with publication, film and music industries. Because the Company’s total assets are less than the $5 million notification threshold, and because the Company’s business activities would likely not be deemed related to Canada’s cultural heritage or national identity, acquisition of a controlling interest in the Company by a non-Canadian investor would not be subject to even the notification requirements under the Investment Canada Act. &nbs p;

The following investments by non-Canadians are subject to notification under the Act:

1. An investment to establish a new Canadian business; and

2. An investment to acquire control of a Canadian business that is not reviewable pursuant to the Act.

The following investments by a non-Canadian are subject to review under the Act:

1. Direct acquisition of control of Canadian businesses with assets of $5 million or more, unless the acquisition is being made by a World Trade Organization (“WTO”) member country investor (the United States being a member of the WTO);

2. Direct acquisition of control of Canadian businesses with assets of $237,000,000 or more by a WTO investor;

3. Indirect acquisition of control of Canadian business with assets of $5 million or more if such assets represent more than 50% of the total value of the assets of the entities, the control of which is being acquired, unless the acquisition is being made by a WTO investor, in which case there is no review;

4. indirect acquisition of control of Canadian businesses with assets of $50 million or more even if such assets represent less than 50% of the total value of the assets of the entities, the control of which is being acquired, unless the acquisition is being made by a WTO investor, in which case there is no review; and

5. An investment subject to notification that would not otherwise be reviewable if the Canadian business engages in the activity of publication, distribution or sale of books, magazines, periodicals, newspapers, film or video recordings, audio or video music recordings, or music in print or machine-readable form.

Generally speaking, an acquisition is direct if it involves the acquisition of control of the Canadian business or of its Canadian parent or grandparent and an acquisition is indirect if it involves the acquisition of control of a non-Canadian parent or grandparent of an entity carrying on the Canadian business. Control may be acquired through the acquisition of actual voting control by the acquisition of voting shares of a Canadian corporation or through the acquisition of substantially all of the assets of the Canadian business. No change of voting control will be deemed to have occurred if less than one-third of the voting control of a Canadian corporation is acquired by an investor.

A WTO investor, as defined in the Act, includes an individual who is a national of a member country of the World Trade Organization or who has the right of permanent residence in relation to that WTO member, a government or government agency of a WTO investor-controlled corporation, limited partnership, trust or joint venture and a corporation, limited partnership, trust or joint venture that is neither WTO-investor controlled or Canadian controlled of which two-thirds of its board of directors, general partners or trustees, as the case may be, or any combination of Canadians and WTO investors.

The higher thresholds for WTO investors do not apply if the Canadian business engages in activities in certain sectors such as uranium, financial services, transportation services or communications.

The Act specifically exempts certain transactions from either notification or review. Included among this category of transactions is the acquisition of voting shares or other voting interests by any person in the ordinary course of that person’s business as a trader or dealer in securities.

(E) TAXATION

Material Canadian Federal Income Tax Consequences

Management of the Company believes that the following general summary accurately describes all material Canadian federal income tax consequences applicable to a holder of common shares of the Company who is a resident of the United States and who is not a resident of Canada and who does not use or hold, and is not deemed to use or hold, his common shares of the Company in connection with carrying on a business in Canada (a “non-resident holder”).

This summary is based upon the current provisions of the Income Tax Act (Canada) (the “ITA”), the regulations there under (the “Regulations”), the current publicly announced administrative and assessing policies of Canada, Customs and Revenue Agency, and all specific proposals (the “Tax Proposals”) to amend the ITA and Regulations announced by the Minister of Finance (Canada) prior to the date hereof. This summary assumes that the Tax Proposals will be enacted in their form as of the date of this Annual Report. This description, except for the Tax Proposals, does not take into account or anticipate any changes in law, whether by legislative, government or judicial action, nor does it take into account provincial, territorial, or foreign tax considerations, which may differ significantly from those, discussed herein.

Dividends

Dividends paid on the common shares of the Company to a non-resident holder will be subject to withholding tax. The Canada-U.S. Income Tax Convention (1980) (the “Treaty”) provides that the normal 25% withholding tax rate under the ITA is reduced to 15% on dividends paid on shares of a corporation resident in Canada (such as the Company) to beneficial owners of the dividends who are residents of the United States, and also provides for a further reduction of this rate to 5% where the beneficial owner of the dividends is a corporation that is a resident of the United States which owns at least 10% of the voting shares of the corporation paying the dividend.

Capital Gains

Under the ITA, a taxpayer’s capital gain or capital loss from a disposition of a share of the Company is the amount, if any, by which his proceeds of disposition exceed (or are exceeded by) the aggregate of his adjusted cost base of the share and reasonable expenses of disposition. One half of a capital gain (the “taxable capital gain”) is included in income, and one half of a capital loss in a year (the “allowable capital loss”) is deductible from taxable capital gains realized in the same year. The amount by which a shareholder’s allowable capital loss exceeds his taxable capital gains in a year may be deducted from a taxable capital gain realized by the shareholder in the three previous or any subsequent year, subject to certain restrictions in the case of a corporate shareholder.

A non-resident holder is not subject to tax under the ITA in respect of a capital gain realized upon the disposition of a share of a public corporation unless the share represents “taxable Canadian property” to the holder thereof. The Company is a public corporation for purposes of the ITA and a common share of the Company will be taxable Canadian property to a non-resident holder if, at any time during the period of five years immediately preceding the disposition, the non-resident holder, persons with whom the non-resident holder did not deal at arm’s length, or the non-resident holder and persons with whom he did not deal at arm’s length together owned not less than 25% of the issued shares of any class of shares of the Company.

Where a non-resident holder who is an individual ceased to be resident in Canada, and at the time he ceased to be a Canadian resident elected to have his Company shares treated as taxable Canadian property, he will be subject to Canadian tax on any capital gain realized on disposition of the Company’s shares, subject to the relieving provisions of the Treaty described below. Shares of the Company may also be taxable Canadian property to a holder if the holder acquired them pursuant to certain tax-deferred “rollover” transactions whereby the holder exchanged property that was taxable Canadian property for shares of the Company.

Where the non-resident holder realized a capital gain on a disposition of the Company shares that constitute taxable Canadian property, the Treaty relieves the non-resident shareholder 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 from natural resources, which is the case for the Company,

(b) The non-resident holder is an individual who was resident in Canada for not less than 120 months during any period of 20 consecutive years preceding, and 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 or are property substituted for property that was owned at that time, or

(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.

Material United States Federal Income Tax Consequences

The following summary is a general discussion of the material United States Federal income tax considerations to U.S. holders of shares of the Company under current law. This discussion assumes that U.S. holders hold their shares of the Company’s common stock as capital assets within the meaning of Section 1221 of the Internal Revenue Code of 1986, as amended (the “Code”). It does not discuss all the tax consequences that may be relevant to particular holders in light of their circumstances or to holders subject to special rules, such as tax-exempt organizations, qualified retirement plans, financial institutions, insurance companies, real estate investment trusts, regulated investment companies, broker-dealers, non-resident alien individuals or foreign corporations whose ownership of shares of the Company is not effectively connected with the conduct of a trade or business in the United States, shareholders who acquired their stock through the exercise of employee stock options or otherwise as compensation, shareholders who hold their stock as ordinary assets and not capital assets and any other non-U.S. holders. In addition, U.S. holders may be subject to state, local or foreign tax consequences. No opinion or representation with respect to the United States Federal income tax consequences to any such holder or prospective holder is being made by the Company herein. Holders and prospective holders should therefore consult with their own tax advisors with respect to their particular circumstances. This discussion covers all material tax consequences.

The following discussion is based upon the sections of the Code, Treasury Regulations, published Internal Revenue Service (“IRS”) rulings, published administrative positions of the IRS and court decisions that are currently applicable, any or all of which could be materially and adversely changed, possibly on a retroactive basis, at any time. This decision does not consider the potential effects, both adverse and beneficial, of any recently proposed legislation that, if enacted, could be applied, possibly on a retroactive basis, at any time. Accordingly, holders and prospective holders of shares of the Company should consult their own tax advisors about the Federal, state, local, estate, and foreign tax consequences of purchasing, owning and disposing of shares of the Company.

U.S. Holders

As used herein, a “U.S. Holder” includes a holder of shares of the Company who is a citizen or resident of the United States, a corporation created or organized in or under the laws of the United States or of any political subdivision thereof, any entity that is taxable as a corporation for U.S. tax purposes and any other person or entity whose ownership of shares of the Company is effectively connected with the conduct of a trade or business in the United States. A U.S. Holder does not include persons subject to special provisions of Federal income tax law, such as tax exempt organizations, qualified retirement plans, financial institutions, insurance companies, real estate investment trusts, regulated investment companies, broker-dealers, non-resident alien individuals or foreign corporations whose ownership of shares of the Company is not effectively connected with conduct of trade or business in the United States, shareholders who acquired their stock through the exercise of employee stock options or otherwise as compensation and shareholders who hold their stock as ordinary assets and not as capital assets.

Distributions on Common Shares of the Company

U.S. Holders receiving dividend distribution (including constructive dividends) with respect to shares of the Company are required to include in gross income for United States Federal income tax purposes the gross amount of such distribution to the extent that the Company has current or accumulated earnings and profits as defined under U.S. Federal tax law, without reduction for any Canadian income tax withheld from such distributions. Such Canadian tax withheld may be credited, subject to certain limitations, against the U.S. Holder’s United States Federal income tax liability or, alternatively, may be deducted in computing the U.S. Holder’s United States Federal taxable income by those who itemize deductions. (See more detailed discussion at “Foreign Tax Credit” below). To the extent that distributions exceed current or accumulated earnings and profits of the Company, they will be treated first as a return of capital up to the U.S. Holder’s adjusted basis in the shares and thereafter as gain from the sale or exchange of the shares. Preferential tax rates for long-term net capital gains are applicable to a U.S. Holder that is an individual, estate or trust. There are currently no preferential tax rates for long-term capital gains for a U.S. Holder that is a corporation.

Dividends paid on the shares of the Company will not generally be eligible for the dividends received deduction provided to corporations receiving dividends from certain United States corporations. A U.S. Holder that is a corporation may, under certain circumstances, be entitled to a 70% deduction of the United States source portion of dividends received from the Company (unless the Company qualifies as a “foreign personal holding company” or a “passive foreign investment company”, as defined below) if such U.S. Holder owns shares representing at least 10% of the voting power and value of the Company. The availability of this deduction is subject to several complex limitations that are beyond the scope of this discussion.

In the case of foreign currency received as a dividend that is not converted by the recipient into U.S. dollars on the date of receipt, a U.S. Holder will have a tax basis in the foreign currency equal to its U.S. dollar value on the date of receipt. Generally, any gain or loss recognized upon a subsequent sale or other disposition of the foreign currency, including the exchange for U.S. dollars, will be ordinary income or loss. However, for tax years after 1997, an individual whose realized foreign exchange gain does not exceed U.S. $200 will not recognize that gain, to the extent that there are not expenses associated with the transaction that meet the requirement for deductibility as a trade or business expense other than travel expenses in connection with a business trip (or as an expense for the production of income).

Foreign Tax Credit

A U.S. Holder who pays (or has withheld from distribution) Canadian income tax with respect to the ownership of shares of the Company may be entitled, at the option of the U.S. Holder, to either a deduction or a tax credit for such foreign tax paid or withheld. Generally, it will be more advantageous to claim a credit because a credit reduces United States Federal income taxes on a dollar-for-dollar basis, while a deduction merely reduces the taxpayer’s income subject to tax. This election is made on a year-by-year basis and applies to all foreign taxes paid by (or withheld from) the U.S. Holder during the year. There are significant and complex limitations that apply to the credit; among which is the general limitation that the credit cannot exceed the proportionate share of the U.S. Holder’s United States Federal income tax liability that the U.S. Holder’s foreign source income bears to this or its w orldwide taxable income. In the determination of the application of this limitation, the various items of income and deduction must be classified into foreign and domestic sources. Complex rules govern this classification process. There are further limitations on the foreign tax credit for certain types of income such as “passive income”, “high withholding tax interest”, “financial services income”, “shipping income”, and certain other classifications of income. The availability of the foreign tax credit and the application of the limitations on the credit are fact specific and holders and prospective holders of shares of the Company should consult their own tax advisors regarding their individual circumstances.

Information Reporting and Backup Withholding

U.S information reporting requirements may apply with respect to the payment of dividends to U.S. Holders of the Company’s common shares. Under Treasury regulations currently in effect, non-corporate holders may be subject to backup withholding at a 31% rate with respect to dividends when such holder (1) fails to finish or certify a correct taxpayer identification number to the payor in the required manner, (2) is notified by the IRS that it has failed to report payments of interest or dividends properly or (3) fails, under certain circumstances, to certify that it has been notified by the IRS that it is subject to backup withholding for failure to report interest and dividend payments. Any amounts withheld under the backup withholding rules from a payment to a U.S. Holder generally will be allowed as a credit against the U.S. Holder’s U.S. federal income tax liability and may entitle the U.S. Holder to a refund, provided that the required information is furnished to the IRS. Certain U.S. Holders, including corporations, are not subject to backup withholding.

Disposition of Common Shares of the Company

A U.S. Holder will recognize a gain or loss upon the sale of shares of the Company equal to the difference, if any, between (i) the amount of cash plus the fair market value of any property received, and (ii) the shareholder’s tax basis in the shares of the Company. This gain or loss will be a capital gain or loss if the shares are a capital asset in the hands of the U.S. Holder, and will be a short-term or long-term capital gain or loss depending upon the holding period of the U.S. Holder. Gains and losses are netted and combined according to special rules in arriving at the overall capital gain or loss for a particular tax year. Deductions for net capital loss are subject to significant limitations. Corporate capital losses (other than losses of corporations electing under Subchapter S of the Code) are deductible to the extent of capital gains. Non-corporate taxpayers may deduct net capital losses, whether short-term or long-germ, up to U.S. $3,000 a year (U.S. $1,500 in the case of a married individual filing separately). For U.S. Holders, which are individuals, any unused portion of such net capital loss may be carried over to be used in later tax years until such net capital loss is thereby exhausted. For U.S. Holders that are corporations (other than corporations subject to Subchapter S of the Code), an unused net capital loss may be carried back three years from the loss year and carried forward five years from the loss year to be offset against capital gains until such net capital loss is thereby exhausted.

Currency Exchange Gains or Losses

U.S. holders generally are required to calculate their taxable incomes in United States dollars. Accordingly, a U.S. holder who purchases common shares of the Company with Canadian dollars will be required to determine the tax basis of such shares in United States dollars based on the exchange rate prevailing on the settlement date of the purchase (and may be required to recognize the unrealized gain or loss, if any, in the Canadian currency surrendered in the purchase transaction). Similarly, a U.S. holder receiving dividends or sales proceeds from common shares of the Company in Canadian dollars will be required to compute the dividend income or the amount realized on the sale, as the case may be, in United States dollars based on the exchange rate prevailing at the time of receipt in the case of dividends and on the settlement date in the case of sales on an established securities exchange. Gain or loss, if any, r ecognized on a disposition of Canadian currency in connection with the described transactions generally will be treated as ordinary gain or loss.

Other Considerations

In the following circumstances, the above sections of this discussion may not describe the United States Federal income tax consequences resulting from the holding and disposition of common shares of the Company (the Company does not believe that it will qualify in the next year, or has qualified within the past three fiscal years, as a “foreign personal holding company”, “foreign investment company”, “passive foreign investment company” or “controlled foreign corporation” as discussed below):

Foreign Personal Holding Company

If at any time during a taxable year more than 50% of the total combined voting power or the total value of the Company’s outstanding shares is owned, directly or indirectly, by five or fewer individuals who are citizens of the United States and 60% or more of the Company’s gross income for such year was derived from certain passive sources (e.g., from dividends received from its subsidiaries), the Company would be treated as a “foreign personal holding company”. In that event, U.S. Holders that hold common shares of the Company (on the earlier of the last day of the Company’s tax year or the last date in which the Company was a foreign personal holding company) would be required to include in gross income for such year their allocable portions of such passive income to the extent the Company does not actually distribute such income.

Foreign Investment Company

If 50% or more of the combined voting power or total value of the Company’s outstanding shares are held, directly or indirectly, by citizens or residents of the United States, United States domestic partnerships or corporations, or estates or trusts other than foreign estates or trusts (as defined by the Code Section 7701(a)(31)), and the Company is found to be engaged primarily in the business of investing, reinvesting, or trading in securities, commodities, or any interest therein, it is possible that the Company might be treated as a “foreign investment company” as defined in Section 1246 of the Code, causing all or part of any gain realized by a U.S. Holder selling or exchanging common shares of the Company to be treated as ordinary income rather than capital gains.

Passive Foreign Investment Company

As a foreign corporation with U.S. Holders, the Company could potentially be treated as a passive foreign investment company (“PFIC”), as defined in Section 1297 of the Code, depending upon the percentage of the Company’s income which is passive, or the percentage of the Company’s assets which are producing passive income (generally 75% or more of its gross income in a taxable year is passive income, or the average percentage of the Company’s assets (by value) during the taxable year which produce passive income or which are held for production of same is at least 50%). Passive income is generally defined to include gross income in the nature of dividends, interest, royalties, rents and annuities; excess of gains over losses from certain transactions in any commodities not arising inter alia from a PFIC whose business is actively involved in such commodities; certain foreign currency gains; and ot her similar types of income. U.S. Holders owning shares of a PFIC are subject to an additional tax and to an interest charge based on the value of deferral of tax for the period during which the common shares of the PFIC are owned, in addition to treatment of gain realized on the disposition of common shares of the PFIC as ordinary income rather than capital gain. However, if the U.S. Holder makes a timely election to treat a PFIC as a qualified electing fund (“QEF”) with respect to such shareholder’s interest therein, the above-described rules generally will not apply. Instead, the electing U.S. Holder would include annually in his gross income his pro rata share of the PFIC’s ordinary earnings and net capital gain regardless of whether such income or gain was actually distributed. A U.S. Holder of a QEF can, however, elect to defer the payment of United States Federal income tax on such income inclusions. Special rules apply to U.S. Holders who own their in terests in a PFIC through intermediate entities or person.

Effective for tax years of U.S. Holders beginning after December 31, 1997, U.S. Holders who hold, actually or constructively, marketable stock of a foreign corporation that qualifies as a PFIC may elect to mark such stock to the market (a “mark-to-market election”). If such an election is made, such U.S. Holder will not be subject to the special taxation rules of PFIC described above for the taxable year for which the mark-to-market election is made. A U.S. Holder who makes such an election will include in income for the taxable year an amount equal to the excess, if any, of the fair market value of the shares of the Company as of the close of such tax year over such U.S. Holder’s adjusted basis in such shares. In addition, the U.S. Holder is allowed a deduction for the lesser of (i) the excess, if any, of such U.S. Holder’s adjusted tax basis in the shares over the fair market value of such share s as of the close of the tax year, or (ii) the excess, if any of (A) the mark-to-market gains for the shares in the Company included by such U.S. Holder for prior tax years, including any amount which would have been included for any prior year but for Section 1291 interest on tax deferral rules discussed above with respect to a U.S. Holder, who has not made a timely QEF election during the year in which he holds (or is deemed to have held) shares in the Company and the Company is a PFIC (“Non-Electing U.S. Holder”), over (B) the mark-to-market losses for shares that were allowed as deductions for prior tax years. A U.S. Holder’s adjusted tax basis in the shares of the Company will be increased or decreased to reflect the amount included or deducted as a result of mark-to-market election. A mark-to-market election will apply to the tax year for which the election is made and to all later tax years, unless the PFIC stock ceases to be marketable or the IRS consents to the revocation of the election.

The IRS has issued proposed regulations that, subject to certain exceptions, would treat as taxable certain transfers of PFIC stock by a Non-Electing U.S. Holder that are generally not otherwise taxed, such as gifts, exchanges pursuant to corporate reorganizations, and transfers at death. Generally, in such cases, the basis of the Company’s shares in the hands of the transferee and the basis of any property received in the exchange for those shares would be increased by the amount of gain recognized. A U.S. Holder who has made a timely QEF election (as discussed below) will not be taxed on certain transfers of PFIC stock, such as gifts, exchanges pursuant to corporate reorganization, and transfers at death. The transferee’s basis in this case will depend on the manner of transfer. The specific tax effect to the U.S. Holder and the transferee may vary based on the manner in which the shares of the Comp any are transferred. Each U.S. Holder should consult a tax advisor with respect to how the PFIC rules affect their tax situation.

The PFIC and QEF election rules are complex. U.S. Holders should consult a tax advisor regarding the availability and procedure for making the QEF election as well as the applicable method for recognizing gains or earnings and profits under the foregoing rules.

Controlled Foreign Corporation

If more than 50% of the voting power of all classes of stock or total value of the stock of the Company is owned, directly or indirectly, by citizens or residents of the United States, United States domestic partnerships and corporations or estates or trusts other than foreign estates or trusts, each of whom owns 10% or more of the total combined voting power of all classes of stock of the Company (“United States shareholder”), the Company could be treated as a “controlled foreign corporation” under Subpart F of the Code. This classification would effect many complex results including the required inclusion by such United States shareholders in income of their pro rata shares of “Subpart F income” (as specifically defined by the Code) of the Company. Subpart F requires current inclusions in the income of United States shareholders to the extent of a controlled foreign corporation’s accumu lated earnings invested in “excess passive” assets (as defined by the Code). In addition, under Section 1248 of the Code, gain from sale or exchange of stock by a holder of common shares of the Company who is or was a United States shareholder at any time during the five year period ending with the sale or exchange is treated as ordinary dividend income to the extent of earnings and profits of the Company attributable to the stock sold or exchanged. Because of the complexity of Subpart F, and because it is not clear that Subpart F would apply to the holders of common shares of the Company, a more detailed review of these rules is outside the scope of this discussion.

If the Company is both a PFIC and controlled foreign corporation, the Company will generally not be treated as a PFIC with respect to United States shareholders of the controlled foreign corporation. This rule generally will be effective for taxable years of the Company ending with or within such taxable years of United States shareholders.

The foregoing summary is based upon the sections of the Internal Revenue Code of 1986, as amended (the “Code”), Treasury Regulations, published Internal Revenue Service (“IRS”) rulings, published administrative positions of the IRS and court decisions that are currently applicable, any or all of which could be materially and adversely changed, possibly on a retroactive basis, at any time. This discussion does not consider the potential effects, both adverse and beneficial, of any recently proposed legislation that, if enacted, could be applied, possibly on a retroactive basis, at any time. Accordingly, holders and prospective holders of shares of the Company should consult their own tax advisors about the Federal, state, local, estate, and foreign tax consequences of purchasing, owning and disposing of shares of the Company.

THE FOREGOING SUMMARY DOES NOT DISCUSS ALL ASPECTS OF CANADIAN OR US FEDERAL INCOME TAXATION THAT MAY BE RELEVANT TO A PARTICULAR HOLDER OF COMMON STOCK IN LIGHT OF SUCH HOLDER'S PARTICULAR CIRCUMSTANCES AND INCOME TAX SITUATION. HOLDERS SHOULD CONSULT THEIR OWN TAX ADVISORS AS TO THE SPECIFIC TAX CONSEQUENCES THAT WOULD RESULT FROM THEIR OWNERSHIP AND DISPOSITION OF COMMON STOCK OF THE COMPANY, INCLUDING THE APPLICATION AND EFFECT OF STATE, LOCAL AND FOREIGN LAWS.

The Company is subject to reporting requirements as a “reporting issuer” under applicable securities legislation in Canada and as a “foreign private issuer” under the Securities Exchange Act of 1934 (the “Exchange Act”). As a result, we must file periodic reports and other information with the Canadian securities regulatory authorities and the Securities and Exchange Commission.

A copy of this Annual Information Form/Form 20-F Annual Report and certain other documents referred to in this Annual Report and other documents filed by us may be retrieved from the system for electronic document analysis and retrieval (“SEDAR”) system maintained by the Canadian securities regulatory authorities at www.sedar.ca or from the Securities and Exchange Commission electronic data gathering, analysis and retrieval system(“EDGAR”) at www.sec.gov/edgar.

(I) SUBSIDIARY INFORMATION

The documents concerning the Company’s subsidiaries referred to in this Annual Report may be inspected at the Company's office at 47 Avenue Road, Suite 200, Toronto, Ontario, Canada, M5R 2G3.

ITEM 11 – QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The Company holds no material financial instruments.

The Company is exposed to foreign currency exchange rate risk as it currently incurs liabilities in United States dollars and Canadian dollars. 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, “Exchange Rate Risk.”

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, and the Company does not maintain significant cash reserves over periods of time that could be materially affected by fluctuations in interest rates or foreign exchange rates.

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 prior 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).

On April 21, 2003, certain corporate changes were made which involved a 7:1 reverse split, buy-back of fractional shares and a private placement offering. These changes and their effect have been fully explained under Item 5(B), Financing Activities.

ITEM 15 CONTROLS AND PROCEDURES

A. Evaluation of Disclosure Controls and Procedures

The Company evaluated the effectiveness of the design and operation of its disclosure controls and procedures (as defined in Rule 13a-14(c) under the Securities Exchange Act of 1934, as amended) as of the end of the period covered by this report (the "Evaluation Date"). Based upon that evaluation, the Chief Executive Officer concluded that, as of the Evaluation Date, the Company's disclosure controls and procedures were effective in timely alerting them to the material information relating to the Company (or the Company's consolidated subsidiaries) required to be included in the Company's periodic SEC filings.

B. Changes in Internal Controls

There were no significant changes made in the Company's internal controls or, to the Company's knowledge, in other factors that could significantly affect these controls subsequent to the Evaluation Date.

Mr. Kam Shah currently assumes the dual role of CEO and CFO and is currently the only executive director of the Company. Given the current size and nature of operations of the Company, strong financial and business background of Mr. Shah and existence of two independent directors out of three, the Company believes that existence of only one executive officer would not adversely affect the Company’s disclosure controls and procedures.

AUDITORS’ REPORT

To the Shareholders of

Dealcheck.com Inc.

We have audited the consolidated balance sheets of Dealcheck.com Inc. as at March 31, 2003 and 2002 and the consolidated statements of operations, cash flows and shareholders’ deficit for the years then ended. These financial statements are the responsibility of the company’s management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audit in accordance with Canadian generally accepted auditing standards and United States generally accepted audited standards. 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.

In our opinion, these consolidated financial statements present fairly, in all material respects, the financial position of the company as at March 31, 2003 and 2002 and the results of its operations and its cash flows for the years then ended in accordance with Canadian generally accepted accounting principles.

Canadian generally accepted accounting principles vary in certain significant respects from accounting principles generally accepted in the United States. Application of accounting principles generally accepted in the United States would have affected results of operations for the year ended march 31, 2003 and the shareholders’ equity as at that date to the extent summarized in Note 14 to the consolidated financial statements.

Comments by Auditor on Canada-United States Reporting Difference

United States reporting standards for auditors require the addition of an explanatory paragraph (following the opinion paragraph) when the financial statements are affected by conditions and events that cast substantial doubt on the company’s ability to continue as a going concern, such as those described in Note 1 to the financial statements.

Although we conducted our audits in accordance with both Canadian generally accepted auditing standards and United States generally accepted auditing standards, our report to the shareholders dated June 16, 2003 is expressed in accordance with Canadian reporting standards which do not permit a reference to such conditions and events in the auditors’ report when these are adequately disclosed in the financial statements.
