FORWARD LOOKING STATEMENTS

This annual report includes “forward looking statements”. All statements, other than statements of historical facts, included herein or incorporated by reference herein, including without limitation, statements regarding our business strategy, plans and objectives of management for future operations and those statements preceded by, followed by or that otherwise include the words “believe”, “expects”, “anticipates”, “intends”, “estimates” or similar expressions or variations on such expressions are forward-looking statements. We can give no assurances that such forward-looking statements will prove to be correct.

Each forward-looking statement reflects our current view of future events and is subject to risks, uncertainties and other factors that could cause actual results to differ materially from any results expressed or implied by our forward-looking statements.

Risks and uncertainties include, but are not limited to:

· our plans and ability to develop and commercialize product candidates and the timing of these development programs;
· clinical development of our product candidates, including the results of current and future clinical trials;
· the benefits and risks of our product candidates as compared to others;
· our maintenance and establishment of intellectual property rights in our product candidates;
· our need for additional financing and our estimates regarding our capital requirements and future revenues and profitability;
· our estimates of the size of the potential markets for our product candidates;
· our selection and licensing of product candidates;

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 based on the change in the focus of our business activities from Oil & Gas to Biotechnology , 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."

We do not currently have the marketing expertise needed to commercialize our products; we will be primarily a pharmaceutical development business subject to all of the risks of a pharmaceutical development business;

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”, "Bontan", “we”, “us”, “our” are used interchangeably in this Annual Report and mean Bontan Corporation Inc. and its subsidiaries.

We do not hold interests in any exploration projects and have no reserves as defined in Canadian National Instrument 51-101 Standards of Disclosure for Oil and Gas Activities ("NI 51-101"). We have changed the focus of our business activity from Oil & Gas to Biotechnology effective December 2012.

FOREIGN PRIVATE ISSUER STATUS AND REPORTING CURRENCY

Foreign Private Issuer Status:

Bontan Corporation Inc. is a Canadian corporation incorporated under the laws of the Province of Ontario. Approximately 41% of its common stock was held by non-United States citizens and residents as of September 30, 2012 being its latest second quarter end. However, our business is administered principally outside the United States and all 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 the International Financial Reporting Standards as issued by the International Accounting Standards Board (“IFRS”)

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

(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. Since we changed the focus of our business from oil & gas to biotechnology since December 2012, the risks set out below relate to the new intended business activities.

Risks Related to our Business

We have a history of operating losses and may never achieve profitability in the future.

We have not generated any business income since fiscal 2010 and have losses for the fiscal year 2013 in the amount of approximately $1.5 million and accumulated deficit of approximately $45 million. We do not have any proven reserves or current production of oil or gas and we have abandoned further involvements in this business. While we expect to bring in persons with significant experience in the biotechnology industry, we have never been involved in the biotechnology industry and have no previous experience with product sales and have no established sales and distribution network.

We expect to be involved in research and development to identify and validate new drug targets that could become marketed drugs for several years to come and will be requiring significant financial resources without any income. We expect these expenses to result in continuing operating losses in the near future.

Our ability to generate future revenue or achieve profitable operations is largely dependent upon our ability to attract the experienced management and know-how to develop new drug candidates and to partner with major pharmaceutical companies to successfully commercialize the drug candidates. It takes many years and significant financial resources to successfully develop pre-clinical or early clinical drug candidate into a marketable drug and we cannot assure you that we will be able to successfully achieve these objectives.

We will be primarily in a pharmaceutical development business and will be subject to all of the risks of a pharmaceutical development business.

As a result, our business must be evaluated in light of the problems, delays, uncertainties and complications encountered in connection with establishing a pharmaceutical development business.

There is a possibility that none of our drug candidates that may be under development in future will be found to be safe and effective, that we will be unable to receive necessary regulatory approvals in order to commercialize them, or that we will obtain regulatory approvals that are too narrow to be commercially viable.

Any failure to successfully develop and obtain regulatory approval for products would have a material adverse effect on our business, financial condition and results of operations.

Clinical trials for our potential product candidates will be expensive and time consuming, and their outcome uncertain.

Before we can obtain regulatory approval for the commercial sale of any product candidate or attract major pharmaceutical company to collaborate with, we will be required to complete extensive clinical trials to demonstrate its safety and efficacy. Clinical trials are very expensive, and are difficult to design and implement. The clinical trial process is also time-consuming and can often be subject to unexpected delays.

The timing of the commencement, continuation and completion of clinical trials may be subject to significant delays relating to various causes, including:

our inability to manufacture or obtain sufficient quantities of materials for use in clinical trials;

delays arising from our collaborative partnerships;

delays in obtaining regulatory approvals to commence a study, or government intervention to suspend or terminate a study;

delays, suspension, or termination of the clinical trials due to the institutional review board or independent ethics board responsible for overseeing the study to protect research subjects at a particular study site;

delays in identifying and reaching agreement on acceptable terms with prospective clinical trial sites;

slower than expected rates of patient recruitment and enrollment;

uncertain dosing issues;

inability or unwillingness of medical investigators to follow our clinical protocols;

variability in the number and types of subjects available for each study and resulting difficulties in identifying and enrolling subjects who meet trial eligibility criteria;

scheduling conflicts with participating clinicians and clinical institutions;

difficulty in maintaining contact with subjects after treatment, which results in incomplete data;

unforeseen safety issues or side effects;

lack of efficacy during the clinical trials;

our reliance on clinical research organizations to conduct clinical trials, which may not conduct those trials with good clinical or laboratory practices; or

other regulatory delays.

The results of pre-clinical studies and initial clinical trials are not necessarily predictive of future results, and our potential product candidates may not have favourable results in later trials or in the commercial setting.

Pre-clinical tests and Phase 1 and Phase 2 clinical trials are primarily designed to test safety, to study pharmacokinetics and pharmacodynamics and to understand the side effects of product candidates and explore efficacy at various doses and schedules. Success in pre-clinical or animal studies and early clinical trials does not ensure that later large-scale efficacy trials will be successful nor does it predict final results; favourable results in early trials may not be repeated in later trials.

A number of companies in the life sciences industry have suffered significant setbacks in advanced clinical trials, even after positive results in earlier trials. Clinical results are frequently susceptible to varying interpretations that may delay, limit or prevent regulatory approvals. Negative or inconclusive results or adverse medical events during a clinical trial could cause a clinical trial to be delayed, repeated or terminated. In addition, failure to construct appropriate clinical trial protocols could result in the test or control group experiencing a disproportionate number of adverse events and could cause a clinical trial to be repeated or terminated.

There is typically an extremely high rate of attrition from the failure of product candidates proceeding through clinical and post-approval trials.

Our success will be dependent upon our corporate collaborations with third parties in connection with services we will need for the development, marketing and commercialization of our products.

The success of our business will be largely dependent on our ability to enter into corporate collaborations regarding the development, clinical testing, regulatory approval and commercialization of our potential product candidates. We may not be able to find new collaborative partners to support our future development, marketing and commercialization of our products, which may require us to undertake research and development and/or commercialization activities ourselves, and may result in a material adverse effect on our business, financial condition, prospects and results of operations.

Even if we are able to find new collaborative partners, our success is highly dependent upon the performance of these new corporate collaborators. The amount and timing of resources to be devoted to activities by future corporate collaborators, if any, are not within our direct control and, as a result, we cannot assure you that any future corporate collaborators will commit sufficient resources to our research and development projects or the commercialization of our potential product candidates. Any future corporate collaborators might not perform its obligations as expected and might pursue existing or other development-stage products or alternative technologies in preference to those being developed in collaboration with us, or may terminate particular development programs, or the agreement governing such development programs.

In addition, if any future collaborators fail to comply with applicable regulatory requirements, the FDA, the European Medicines Agency (“EMA”), the Therapeutic Products Directorate (“TPD”) or other authorities could take enforcement action that could jeopardize our ability to develop and commercialize our potential product candidates. Despite our best efforts to limit them, disputes may arise with respect to ownership of technology developed under any such corporate collaboration.

We will rely on proprietary technology, the protection of which can be unpredictable and costly.

Our success will depend in part upon our ability to obtain patent protection or patent licenses for our future technology and products. Obtaining such patent protection or patent licenses can be costly and the outcome of any application for patent protection and patent licenses can be unpredictable. In addition, any breach of confidentiality by a third party by premature disclosure may preclude us from obtaining appropriate patent protection, thereby affecting the development and commercial value of our technology and products.

Some of our future products may rely on licenses of proprietary technology owned by third parties and we may not be able to maintain these licenses on favourable terms.

The manufacture and sale of some of the products we hope to develop may involve the use of processes, products, or information, the rights to which are owned by third parties. Such licenses frequently provide for limited periods of exclusivity that may be extended only with the consent of the licensor. If licenses or other rights related to the use of such processes, products or information are crucial for marketing purposes, and we are not able to obtain them on favourable terms, or at all, the commercial value of our products will be significantly impaired. If we experience delays in developing our products and extensions are not granted on any or all of such licenses, our ability to realize the benefits of our efforts may be limited.

We will have additional future capital needs and there are uncertainties as to our ability to raise additional funding.

We will require substantial additional capital resources to develop potential product candidates, obtain regulatory approvals and ultimately to commercialize such product candidates.

In addition, our future cash requirements may vary materially from those now expected. For example, our future capital requirements may increase if:

· we experience scientific progress sooner than expected in our future discovery, research and development projects, if we expand the magnitude and scope of these activities, or if we modify our focus as a result of our discoveries;

· we experience setbacks in our progress with pre-clinical studies and clinical trials are delayed;

· we experience delays or unexpected increased costs in connection with obtaining regulatory approvals;

· we are required to perform additional pre-clinical studies and clinical trials;

· we experience unexpected or increased costs relating to preparing, filing, prosecuting, maintaining, defending and enforcing patent claims; or

· we elect to develop, acquire or license new technologies and products.

We could potentially seek additional funding through corporate collaborations and licensing arrangements or through public or private equity or debt financing. However, if our future research and development activities do not show positive progress, or if capital market conditions in general, or with respect to life sciences or development stage companies such as ours in particular, are unfavourable, our ability to obtain additional funding on acceptable terms, if at all, will be negatively affected. Additional financing that we may pursue may involve the sale of our common shares or financial instruments that are exchangeable for or convertible into our common shares which could result in significant dilution to our shareholders.

If sufficient capital is not available, we may be required to delay, reduce the scope of, eliminate or divest of one or more of our research or development projects, any of which could have a material adverse effect on our business, financial condition, prospects or results of operations.

We will be subject to risks associated with doing business globally.

As a pharmaceutical company our operations are likely to expand in the European Union and worldwide, we will be subject to political, economic, operational, legal, regulatory and other risks that are inherent in conducting business globally. These risks include foreign exchange fluctuations, exchange controls, capital controls, new laws or regulations or changes in the interpretation or enforcement of existing laws or regulations, political instability, macroeconomic changes, including recessions and inflationary or deflationary pressures, increases in prevailing interest rates by central banks or financial services companies, economic uncertainty, which may reduce the demand for our potential products or reduce the prices that our potential customers will be willing to pay for our products, import or export restrictions, tariff increases, price controls, nationalization and expropriation, changes in taxation, diminished or insufficient protection of intellectual property, lack of access to impartial court systems, violations of law, including the U.S. Foreign Corrupt Practices Act and the U.K. Bribery Act, disruption or destruction of operations or changes to the Company’s business position, regardless of cause, including war, terrorism, riot, civil insurrection, social unrest, strikes and natural or man-made disasters, including famine, flood, fire, earthquake, storm or disease. The impact of any of these developments, either individually or cumulatively, could have a material adverse effect on our business, financial condition and results of operations.

We may face exposure to adverse movements in foreign currency exchange rates while completing international clinical trials and when our products will be commercialized.

We intend to generate revenue and expenses internationally that are likely to be primarily denominated in U.S., Euros and other foreign currencies. Our intended international business will be subject to risks typical of an international business including, but not limited to, differing tax structures, a myriad of regulations and restrictions, and general foreign exchange rate volatility. A decrease in the value of such foreign currencies relative to the Canadian dollar could result in losses in revenues from currency exchange rate fluctuations. Conversely, an increase in the value of such foreign currencies relative to the Canadian dollar could negatively impact our operating expenses. To date, we have not hedged against risks associated with foreign exchange rate exposure. We cannot be sure that any hedging techniques we may implement in the future will be successful or that our business, results of operations, financial condition and cash flows will not be materially adversely affected by exchange rate fluctuations.

Risks Related to Ownership of our Stock

There is currently a limited trading market for our common shares.

There currently is a limited public market for our common shares. Further, although our common shares are currently quoted on the OTC Bulletin Board, trading of our common shares may be extremely sporadic. As a result, an investor may find it difficult to sell, or to obtain accurate quotations of the price of, our common shares. There can be no assurance that a more active trading market for our common shares will develop. Accordingly, investors must assume they may have to bear the economic risk of an investment in our common shares for an indefinite period of time.

Risks related to penny stocks.

Our common shares are subject to regulations prescribed by the SEC relating to “penny stock.” These regulations impose additional sales practice requirements on broker-dealers who sell such securities to persons other than established customers and accredited investors (as defined in Rule 501 of the U.S. Securities Act of 1933). These regulations could adversely impact market demand for our shares and adversely impact our trading volume and price.

The issuance of common shares upon the exercise of our outstanding warrants and options will dilute the ownership interest of existing stockholders and increase the number of shares eligible for future resale.

The exercise of some or all of our outstanding warrants and options could significantly dilute the ownership interests of our existing shareholders. As of March 31, 2013, we had outstanding warrants to purchase an aggregate of approximately 66 million common shares and outstanding options to purchase an aggregate of approximately 5.4 million common shares. To the extent the warrants and options are exercised, additional common shares will be issued and that issuance will increase the number of shares eligible for resale in the public market. The sale of a significant number of shares by our shareholders, or the perception that such sales could occur, could have a depressive effect on the public market price of our common shares.

Your investment return may be reduced if we lose our foreign private issuer status.

We are a “foreign private issuer,” as such term is defined in Rule 405 under the U.S. Securities Act of 1933, and, therefore, we are not required to file quarterly reports on Form 10-Q or current reports on Form 8-K with the SEC. In addition, the proxy rules and Section 16 reporting and short-swing profit recapture rules are not applicable to us. 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 SEC compliance costs.

We may be treated as a passive foreign investment company for U.S. tax purposes, which could subject United States investors to significant adverse tax consequences.

A foreign corporation will be treated as a passive foreign investment company, or PFIC, for U.S. federal income taxation purposes, if in any taxable year either: (a) 75% or more of its gross income consists of passive income; or (b) 50% or more of the value of the company’s assets is attributable to assets that produce, or are held for the production of, passive income. Based on our current income and assets and our anticipated future operations, we believe that we currently are not a PFIC. U.S. stockholders of a PFIC are subject to a disadvantageous U.S. income tax regime with respect to the income derived by the PFIC, the distributions they receive from the PFIC, and the gain, if any, they derive from the sale or other disposition of their shares in the PFIC. Because PFIC status is a fact-intensive determination made on an annual basis, no assurance can be given that we are not or will not become classified as a PFIC. The PFIC rules are extremely complex. A U.S. person is encouraged to consult his or her U.S. tax advisor before making an investment in our shares.

U.S. shareholders may not be able to enforce civil liabilities against us.

We are a corporation organized under the laws of the Province of Ontario, Canada. Most of our directors and executive officers are non-residents of the United States. Because a substantial portion of their assets and currently all of our assets are located outside the United States, it may not be possible for you to effect service of process within the United States upon us or those persons. Furthermore, it may not be possible for you to enforce against us or them in the United States, judgments obtained in U.S. courts based upon the civil liability provisions of the U.S. federal securities laws or other laws of the United States. There is doubt as to the enforceability, in original actions in Canadian courts, of liabilities based upon the U.S. federal securities laws and as to the enforceability in Canadian courts of judgments of U.S. courts obtained in actions based upon the civil liability provisions of the U.S. federal securities laws.

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 in 1973 under the original name of Kamlo Gold Mines Limited. We were inactive until 1985. Between 1986 and 1992, our company was involved in the development of a new technology for the marine propulsion business. During this period, our company went through three name changes.

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

Our company remained inactive after the closure of the snack food business in November 1996 until December 1998 when we changed our 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, our company raised $3.2 million, which we invested in various projects and companies over the next two years as per the new business strategy of our company. Unfortunately, the IT sector performed poorly since 2001 and new and emerging technology-based businesses suffered significant losses, financial problems and bankruptcies. These factors adversely affected our company’s investments and its profitability. Our company had to write off all its investments by the end of the fiscal 2003.

In April 2003, our company changed its business focus to the natural resource industry and completed a private placement of approximately 8.9 million common shares, raising approximately USD $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.

Diamond mining operations discontinued in December 2004. Our company sold its interest in an oil exploration project in Papua New Guinea in July 2005 for USD $3.2 million. Our company’s cost of this project was approximately USD $1.6 million. Further, in October 2004, our company acquired a working interest in a gas exploration project in Louisiana, USA. Between March 2005 and September 2005, our 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.

In the fiscal 2010, we acquired 4.70% working interest in two off-shore drilling licenses in the Levantine Basin, approximately forty kilometres off the West coast of Israel, through our holding of 76.79% equity interest in Israel Petroleum Company Limited (“IPC Cayman”). This indirect working interest was disposed of for US$ 5 million in cash and certain other non-cash items under a settlement agreement on June 29, 2012with our minority shareholder of IPC Cayman.

In December 2012, the Company decided to change the focus of its business activities from oil and gas to biotechnology mainly due to the increasing difficulty in getting access to viable oil & gas projects and also due to the potentially more profitable business opportunities which currently exist in the biotechnology sector. On March 21, 2013, the Company signed a letter of intent with Portage Pharma Ltd, a biotech private limited company formed under the laws of the British Virgin Islands (“Portage”) to acquire Portage Pharma Ltd through exchange of shares. The transaction was completed on June 4, 2013.

Our company’s registered office is situated at 47 Avenue Road, Suite 200 Toronto, Ontario, Canada M5R 2G3. We are a reporting issuer in the province of Ontario.

(B) BUSINESS OVERVIEW

During the fiscal year 2013, we resolved our extensive litigations with the minority shareholder of IPC Cayman and signed a settlement agreement with them surrendering our 76.79% equity in IPC Cayman for US$ 5 million among other things. The following are the details of the events leading to the final settlement:

On December 16, 2011, the Company signed a settlement agreement (“Settlement agreement”) with IPC Cayman, International Three Crown Petroleum LLC (“ITCP”), Three Crown Petroleum LLC (“TCP”) and Mr. Howard Cooper (“IPC Parties”). The Company agreed to transfer all its equity in IPC Cayman on closing for a total price of US$15 million, which was revised subsequently to $ 5 million plus other future payments as discussed below, and a 0.25% Overriding Royalty Interest (“ORI”) in the Israeli Project in addition, all 5 million warrants issued to ITC and 390,000 options issued to IPC Cayman consultants had been surrendered and cancelled without any compensation. The price of US$15 million was to consist of cash of US$10 million with the balance covered by two promissory notes carrying interest at 5% per annum and secured by additional ORI of 0.25% and a guarantee from IPC Cayman. One promissory note for US$2 million was payable on or before November 9, 2012 and another for US$3 million was payable on or before November 9, 2013. In the event of requests by the IPC Parties for an extension, or the occurrence of certain financing activities, the Company might receive up to a further US$500,000 in non-refundable deposits. The Company might also receive up to an additional US$ 3 million based on the price of Shaldieli shares after two years.

The Company received a non-refundable deposit of US$250,000. IPC Parties exercised its extension right on March 12, 2012 by paying to the Company’s tax escrow agent a further non-refundable deposit of US$125,000 and extended the closing date to April 25, 2012. This date was extended to May 14, 2012 for which the IPC Parties paid to the Company an extension fee of US$ 100,000. The original settlement agreement was finally revised and closed on June 29, 2012.

As per the terms of the revised settlement agreement the Company received US$ 5 million and surrendered all its shares in IPC Cayman for cancellation. The Company and IPC Parties exchanged mutual releases and dismissed all lawsuits against each other and against IPC Oil and Gas Holdings Ltd. (Formerly, Shaldieli Ltd.) and certain of its promoters.

As additional consideration, on or before December 31, 2012, based on a revaluation of the surrendered shares to be performed by the IPC Parties, Bontan was to either receive (i) at the option of the IPC Parties, either a payment of US$9.625 million or a payment of US$6.625 million plus delivery of a US$3.0 million promissory note due on November 8, 2013, carrying 5% p.a. interest and secured by an IPC guarantee, a 0.15% Overriding Royalty Interest (ORI) and a pledge of 23% of the IPC Shares, or (ii) the right to exercise an option to purchase 49.27% of the issued and outstanding share capital of IPC Cayman on a fully diluted basis for an exercise price of US$4,927.(IPC Cayman currently holds 144,821,469 shares of Shaldieli).

However, on December 31, 2012, the Company learnt of the failure of the two exploration wells drilled under the Israeli licenses and as a result decided to abandon further efforts in securing any more interest in IPC Cayman. The company also cancelled 2 million warrants originally issued to another party in connection with this project.

Portage is a biotechnology company engaged in researching and developing products through to proof of concept with an early focus on unmet clinical needs and orphan drugs. Following proof of concept, Portage would look to sell or licence the products to Big Pharma.

Portage currently holds a master license to the Antennapedia platform for all pathologies (except oncology).

As of March 31, 2013, Bontan Corporation had a single wholly owned subsidiary, 1843343 Ontario Inc., incorporated in Ontario, Canada on January 31, 2011. Although the subsidiary has had no activity since its inception, the name of this subsidiary was changed to Portage Services Ltd., on July 11, 2013,

On April 5, 2013, the Company incorporated another wholly owned subsidiary, Portage Acquisition Inc., in the British Virgin Islands.

(D) PROPERTY PLANTS AND EQUIPMENT

We currently lease office space at 47 Avenue Road, Suite 200, and Toronto, Ontario, Canada for approximately $2,300 per month. The leased area is approximately 950 square feet. Our current lease agreement is a month to month arrangement.

Overview

Key activities during fiscal 2013 were:

a.	On June 29, 2012, the Company disposed of, under a settlement agreement, its indirect 4.70% working interest in two off-shore drilling licenses in the Levantine Basin through its holding of 76.79% equity interest in Israel Petroleum Company Limited (“IPC Cayman”).

On December 31, 2012, the Company fully abandon all efforts in pursuing further recovery under the settlement agreement after learning of the failure of two exploratory wells under the drilling licences to identify any oil or gas. All costs previously capitalized relating to the Israeli Project were off set against cash received and warrants cancelled, resulting in a net recovery of $230,455.

In December 2012, the Company announced a new focus on business within the biotechnology industry and on March 12, 2013 it signed a letter of intent with Portage Pharma Ltd, a biotech private limited company formed under the laws of the British Virgin Islands (“Portage”) to acquire Portage through exchange of shares. The transaction was completed on June 4, 2013.

During most part of fiscal 2012, we were mainly engaged in negotiations with IPC Cayman management to work out an acceptable out of court settlement and to end all legal disputes. A settlement agreement was reached in December 2011 and we were able to get US$475,000 and an overriding royalty interest of 0.25% on the two licenses. However, the settlement agreement was extended and revised and finally closed on June 29, 2012. Further details of these agreements are explained elsewhere in this report.

Key activities during the fiscal 2011 were:

a.	We completed our private placement which began in December 2009 in April 2010 and raised an additional approximately $2.3 million.

b.	The following key development occurred on the Israeli project –

·	Signing of a joint operating agreement with an operator on October 6, 2010.

·	Securing a drill rigs for potential drilling of an exploratory well in early 2012.

·	Securing extension on the Sara and Myra licenses to July 13, 2012 from Petroleum Commissioner in Israel in May 2011.

·	Completing 3D analysis in July 2011.

c.	Our subsidiary IPC Cayman set up IPC Israel in May 2010 and as a result, it became limited partner and we lost control over the financial reporting process of IPC Cayman and decided to deconsolidate the results of IPC Cayman effective May 18, 2010.

d.	We initiated extensive legal actions against the manager of IPC Cayman and against Shadieli Ltd., an Israeli shell in which the manager of IPC Cayman agreed to roll all the interest in IPC Israel for 90% equity without our knowledge or consent.

Income - During the year ended March 31, 2013, the Company received an extension fee of US$100,000 which has been included as other income. No revenue was recognized during the years ended March 31, 2012 and 2011

Expenses

The overall analysis of the expenses is as follows:

Fiscal year ended March 31	2013	2012	2011

Operating expenses	$ 553,428	$ 249,690	$ 379,636

	$ 1,571,951	$ 2,470,378	$ 3,779,638

Operating Expenses

Fiscal year ended March 31		2013	2012	2011

Travel, meals and entertainment		$ 174,142	$ 32,114	$131,976
	Shareholder information	284,606	131,575	148,610
	Other	94,680	86,001	99,050

		$ 553,428	$ 249,690	$379,636

Travel, meals and entertainment

Approximately $ 160,000 was reimbursed to Mr. Terence Robinson, the key consultant for his expenses and travels in Europe and Israeli in connection with the Israeli project and exploring new business opportunities in biotechnology during fiscal 2013. Mr. Robinson’s contract was terminated effective April 1, 2013.

Travel, meals and entertainment expenses for fiscal 2012 were substantially incurred by our CEO, Kam Shah and the key consultant, Mr. Terence Robinson and other consultants and lawyers in visiting Israel in connection with the Israel Project. As explained earlier, most part of fiscal 2012 was spent in litigation and negotiations for an out of court settlement which involved minimum travels. These expenses were therefore significantly less in fiscal 2012 compared to fiscal 2011.

Increased travel costs during fiscal 2011 was caused by several visits to Israel and Grand Cayman in connection with our litigations in those places and also visiting Vancouver, USA and UK in earlier part of the fiscal year in connection with the Israeli Project and fund raising efforts.

Shareholder information

Shareholder information costs comprise investor and media relations fee, costs of holding annual general meeting of the shareholders and various regulatory filing fees.

Major cost (approximately 95%) consists of media relation and investor relation services provided by Current Capital Corp. (“CCC”) under contracts dated July 1, 2004, for a total monthly fee of US$10,000. Current Capital Corp. is a shareholder Corporation where the Chief Executive and Financial Officer of the Company provide accounting services.

During fiscal year, CCC was paid $ 119,192 towards media and investor relation services, which is consistent with payments made in fiscal years 2012 and 2011. In addition, CCC was paid $ 150,000 on March 31, 2013 as an additional fee for cancellation of all future finder’s fee claims on proceeds of any warrants to be exercised. Contracts with CCC were terminated effective March 31, 2013.

Other operating costs

These costs include rent, telephone, Internet, transfer agents fees and other general and administration costs.

There was no major change on a year over year basis.

Consulting fees and payroll	2013	2012	2011

Fees settled in common shares	179,141	7,171	91,714
Fee settled by issuance of options	-	-	181,329
Fee settled in cash	562,018	425,436	505,856
Payroll	47,806	46,158	39,738
	$ 788,965	$ 478,765	$ 818,637

Consulting fees for fiscal 2013 include 3,045,000 shares issued under the existing Consultant Stock Compensation Plans to the CEO- Kam Shah, two consultants –Terence Robinson and John Robinson and two independent directors as bonus on successful resolution of the litigation and settlement relating to the Company’s interest in the Israeli project. These shares were valued at market on the date of their issuance. Cash fee also included a bonus of $ 50,000 paid to the CEO –Kam Shah and $ 40,000 each paid to the two consultants, Terence Robinson and John Robinson for early termination of their consulting contracts which were terminated effective April 1, 2013.

The Company did not issue any shares or options to any consultants during the fiscal year 2012.Cash fee consisted of consulting fee charged by the CEO, audit committee members and two other consultants and were consistent with prior fiscal year. Payroll included value of $3,120 representing 50,000 shares granted under a compensation plan to an employee.

Major reduction in consulting fee during the fiscal year 2012 was mainly due to non-consolidation of IPC Cayman. The previous year’s fees included fees of approximately $266,000 to the IPC Cayman consultants.

The following details relate to the fiscal year 2011:

a.	Fees settled by shares include 120,000 shares issued to two independent consultants and 15,000 shares issued to the employee in respect of their services during the year.

950,000 options were issued in August 2010 to eight consultants and valued at $ 181,329 using Black-Scholes option price model. 300,000 of these options were issued to three directors. These options expire in five years and can be exercised to acquire equal number of common shares at an exercise price of US$0.35 per share.

c.	Cash fee includes approximately $402,000 paid to the CEO and two key consultants, Mr. Terence Robinson and Mr. John Robinson.

Write down of short term investments

During fiscal 2013, the Company’s short term investments included four securities whose market price showed continuous decline and were therefore written down by approximately $162,000 at March 31, 2013 and then disposed of prior to the end of the fiscal year. As a result, the Company holds no further investments as at March 31, 2013.

The Company’s investment portfolio had five marketable securities at the beginning of the fiscal year 2012, one of which was fully written off. Another security was adjusted down by $ 111,000 to its fair value and later sold. The remaining three securities were still being held at the fiscal year end. However, their fair value declined significantly and the decline was considered other than temporary and therefore management decided to write off approximately $ 665,000 against carrying costs of these securities.

As at March 31, 2011, the Company’s short term investment portfolio included four securities whose market price showed continued decline which was considered other than temporary. The carrying costs of these securities were therefore written down by $386,672 in line with their market value as at March 31, 2011.

Loss (Gains) on disposal of short term investments

During fiscal 2013, three marketable securities with adjusted costs of approximately $45,800 were disposed for $46,300, resulting in a net realized gain of approximately $500.

During the fiscal 2012, four marketable securities with adjusted costs of approximately $747,000 were disposed of for $663,000, resulting in a net realized loss of approximately $ 84,000. The disposals were made to generate more cash flow to meet litigation and operational costs.

During the fiscal year 2011, nine securities with carrying cost of $1.9 million were disposed of for approximately $1 million. Three securities alone had a combined loss of approximately $ 796,000. The significant disposal was mainly caused by the need for additional cash to meet litigation costs.

Professional fees

Professional fees consisted of:

	2013	2012	2011
	(in $000’)
Audit & Related fees	$ 33	$ 66	$ 70
Legal	212	915	1,152
Insurance claim received against legal costs	-	(110)	-
	$ 245	$ 871	$ 1,222

Professional fees for fiscal 2013 included audit fee of $ 45,000 which was partly offset by reversal of previous year’s excess provision of $ 15,000 and approximately $ 182,000 in legal fees relating to litigations against IPC Cayman which eventually resulted in settlement in June 2012.

As explained elsewhere in this report, the Company was forced to initiate legal actions against the manager of its subsidiary, IPC Cayman to protect its interest in Israeli project. The litigation initiatives required the Company to hire expensive lawyers in Israel, USA and Cayman Islands. Litigation proceedings began in December 2010 until May 2011 and after that out of court settlement negotiations began which also required heavy involvement of the same lawyers. Thus, for both the fiscal years 2012 and 2011, legal costs were the major costs for the Company.

During the fiscal 2012, we were able to successfully claim some of the legal costs incurred in the past from our insurance company under the directors and officers insurance, which approved a net of $110,000 against our claim.

Bank charges, interest and fees

Small increase in charges during the fiscal 2013 compared to fiscal 2012 was largely due to higher volume of wire transfers resulting in higher wire handling fees.

Charges were substantially lower in 2012 compared to 2011 due to limited number of transactions. Besides, 2011 included interest costs of approximately 1,500 related to loans settled in that fiscal year.

(B) Liquidity and Capital Resources

Working Capital

As at March 31, 2013, the Company had a net working capital of approximately $3.0 million compared to a working capital of $4.9 million as at March 31, 2012. The lower working capital at the end of fiscal 2013 resulted from full adjustment of net exploration and evaluation expenditure recoverable of approximately $5.4 million on settlement during fiscal 2013through cash receipt of $ 5 million and settlement of liabilities – mostly pending legal costs – of approximately $ 600,000.

Operating cash flow

During the fiscal year 2013, operating activities required a net cash outflow of approximately $1.8 million mainly due to the payments made toward accounts payable. This was met from the funds received under settlement in respect of exploration and evaluation expenditure recoverable.

During the fiscal year 2012, operating activities required a net cash outflow of approximately $1.3 million mainly due to increased legal costs and cash fees. This was met from the available cash, cash received form settlement and sale of short term investments.

During the fiscal year 2011, operating activities required a net cash outflow of approximately $ 2.6 million which was met from the available cash and cash generated from investments and equity financing.

While the Company’s fixed overhead costs are expected to reduce significantly due to termination of consulting contracts of Messers Robinsons and CCC, the operational costs are expected to increase due to the proposed acquisition of Portage Pharma, which was completed in June 2013 and research and development costs expected on new drug development plans.

Investing cash flows

During fiscal year, investing activities generated a net cash flow of approximately $ 5 million arising from settlement relating to disposal of our indirect 4.70% interest in two offshore drilling licenses in Israel held through the 76.79% equity of IPC Cayman as more fully explained under item 4 (B) - business overview.

During fiscal 2012, investing activities generated net cash flow of approximately $ 1 million. $383,887 was received as part of the original settlement agreement on December 16, 2011 relating to our interest in the Israeli Project. The said agreement was subsequently revised on June 29, 2012 as more fully explained under item 4 (B) – business overview. The balance of approximately $ 700,000 was received from disposal of four of the marketable securities.

During the fiscal year 2011, investing activities generated a net cash flow of approximately $ 630,000. Approximately $ 940,000 was generated through disposal of nine marketable securities to meet approximately $ 310,000 contributed to IPC Cayman towards the exploration costs on the Israeli Project and the balance was used towards operating cash requirements.

Financing cash flows

There were no financing activities during the fiscal year 2013 and 2012.

Financing cash flow in fiscal 2011 arose from equity financing of approximately $ 2.1 million which was used to settle short term loans of $ 1.1 million and $ 1 million towards financing the subsidiary.

Equity financing in fiscal 2011

During the fiscal year 2011, the Company raised a net of $ 2.1 million in private placement which began in November 2009 and ended on April 30, 2010.This private placement required issuance of 12.7 million additional common shares of the company and 13.9 million warrants and a finder’s fee of 10% in cash and warrants.

Further 600,000 warrants were exercised during the fiscal 2011 by two shareholders for a total cash price of $60,503.

The funds raised were spent in settling all short term loans of approximately $ 1.1 million, in advances made to subsidiary, IPC Cayman of approximately $1 million.

Approximately $ 5.5 million was raised through two private placements. The first one began in December 2008 and completed in October 2009 and raised net of US$ 450,000. The second one began in December 2009 and until March 31, 2010 raised approximately $ 5 million. This private placed closed on April 30, 2010 and an additional approximately $ 2 million was raised. These private placements were subject to 10% finder’s fee in cash and additional 10% fee in warrants payable to various persons including Current Capital Corp., a related party and Mr. Howard Cooper, the sole director and president of our subsidiary, IPC Cayman.

Debt funding in fiscal 2011

We borrowed short term loans totalling to approximately $1.2 million as at March 31, 2010. These loans carried interest between 5% and 10% per annum. The loans were fully settled with accumulated interest subsequent to March 31, 2010 from the additional funds raised through private placement

The Company has not spent any funds on research and development during the fiscal years 2013, 2012 and 2011.

(D) TREND INFORMATION

There are no other trends, commitments, events or uncertainties presently known to management that are reasonably expected to have a material effect on the Company’s business, financial condition or results of operation other than uncertainty as to the speculative nature of the business (Refer to the heading entitled “Risk Factors”).

(E) OFF-BALANCE SHEET ARRANGEMENTS

At March 31, 2013, 2012, and 2011, the Company did not have any off balance sheet arrangements, including any relationships with unconsolidated entities or financial partnership to enhance perceived liquidity.

(F) CONTRACTUAL OBLIGATIONS

None.

(G) SAFE HARBOUR

Not applicable.

Mandate of the Board

The Board has adopted a mandate, in which it has explicitly assumed responsibility for the stewardship of Bontan Corporation Inc. In carrying out its mandate the Board holds at least four meetings annually. The frequency of meetings, as well as the nature of the matters dealt with, will vary from year to year depending on the state of our business and the opportunities or risks, which we face from time to time. The Board held a total of 14 meetings, mostly by way of conference calls, during our financial year ended March 31, 2013. To assist in the discharge of its responsibilities, the Board has designated one standing committee: an Audit Committee, which was re-named as Audit and Compensation Committee effective June 27, 2013.as more particularly discussed below.

Audit and Compensation Committee (“ACC”)

The members of the ACC consist of Jim Mellon, Greg Bailey and Kam Shah. Jim Mellon and Greg Bailey are the independent directors and Kam Shah is an executive director. Jim Mellon is the chairman of the Committee. The ACC was approved in the board meeting on June 27, 2013. Prior to June 27, 2013, the Company had an Audit Committee consisting of Dean Bradley and Brett Rees, two independent directors who resigned effective June 3, 2013.

The ACC is charged with overseeing the Company's accounting and financial reporting policies, practices and internal controls. The committee reviews significant financial and accounting issues and the services performed by and the reports of our independent auditors and makes recommendations to our Board of Directors with respect to these and related matters.

The Company’s Audit Committee’s charter was detailed in the annual report for fiscal 2005. The Charter became effective on August 2, 2005.

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;

·	pre-approving all non-audit services and recommending the appointment of external auditors; and

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

·	Reviewing and approving all employee and consultants contracts, bonuses and other compensation matters

The Company is in the process of preparing an updated Charter for the ACC.

Corporate Governance Committee

The Company does not have a separate corporate governance committee. The management in conjunction with the ACC has developed and updated corporate governance practices and policies, code of ethics and corporate disclosure policy which form part of our internal control over financial reporting manual.

(D) EMPLOYEES

The Company presently has one employee who serves as assistant to the chief financial officer. It uses the services of consultants from time to time.

(E) SHARE OWNERSHIP

The Company usually creates two Plans, Consultants Stock Compensation Plan and Stock Option Plan.

As at July 24, 2013, the date of this report, the Company had one active Consultants Stock Compensation Plan and four active Stock Option Plans. Details of these Plans and movements therein during the fiscal 2013 are given in Notes 6(c) and 7(a) respectively to the consolidated financial statements for the fiscal 2013. As of the date of this report, there were 5,061,667 common shares registered under the Consultants Stock Compensation Plan and not yet allotted, and 3,388,453 outstanding options under the Stock Option Plans.

All shares and options under previous plans have been issued and fully vested.

The objective of these stock plans is to provide for and encourage ownership of our common shares by our directors, officers, consultants and employees and those of any subsidiary companies so that such persons may increase their stake in our company and benefit from increases in the value of the common shares. The Plans are designed to be competitive with the benefit programs of other companies in the natural resource industry. It is the view of management that the plans are a significant incentive for the directors, officers, consultants and employees to continue and to increase their efforts in promoting our operations to the mutual benefit of both our company and such individuals and also allows us to avail of the services of experienced persons with minimum cash outlay.

The following table sets forth the share ownership of our executive officers and directors as at July 24, 2013:

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.

The Company’s articles of incorporation do not place any restrictions on the Company’s objects and purposes.

Certain Powers of Directors

The Business Corporations Act (Ontario) (the "OBCA") requires that every director who is a party to a material contract or transaction or a proposed material contract or transaction with a corporation, or who is a director or officer of, or has a material interest in, any person who is a party to a material contract or transaction or a proposed material contract or transaction with the corporation, shall disclose in writing to the corporation or request to have entered in the minutes of the meetings of directors the nature and extent of his or her interest, and shall refrain from voting in respect of the material contract or transaction or proposed material contract or transaction unless the contract or transaction is: (a) an arrangement by way of security for money lent to or obligations undertaken by the director for the benefit of the corporation or an affiliate; (b) one relating primarily to his or her remuneration as a director, officer, employee or agent of the corporation or an affiliate; (c) one for indemnity of or insurance for directors as contemplated under the OBCA; or (d) one with an affiliate. However, a director who is prohibited by the OBCA from voting on a material contract or proposed material contract may be counted in determining whether a quorum is present for the purpose of the resolution, if the director disclosed his or her interest in accordance with the OBCA and the contract or transaction was reasonable and fair to the corporation at the time it was approved.

The Company's by-laws provide that the directors shall from time to time determine by resolution the remuneration to be paid to the directors, which shall be in addition to the salary paid to any officer or employee of the Company who is also a director. The directors may also by resolution award special remuneration to any director in undertaking any special services on the Company's behalf other than the normal work ordinarily required of a director of the Company. The by-laws provide that confirmation of any such resolution by the Company's shareholders is not required.

The Company's by-laws also provide that the directors may: (a) borrow money upon the credit of the Company; (b) issue, reissue, sell or pledge bonds, debentures, notes or other evidences of indebtedness or guarantee of the Company, whether secured or unsecured; (c) to the extent permitted by the OBCA, give directly or indirectly financial assistance to any person by means of a loan, a guarantee on behalf of the Company to secure performance of any present or future indebtedness, liability or other obligation of any person, or otherwise; and (d) mortgage, hypothecate, pledge or otherwise create a security interest in all or any currently owned or subsequently acquired real or personal, movable or immovable, tangible or intangible, property of the Company to secure any such bonds, debentures, notes or other evidences of indebtedness or guarantee or any other present or future indebtedness, liability or other obligation of the Company.

The directors may, by resolution, amend or repeal any by-laws that regulate the business or affairs of the Company. The OBCA requires the directors to submit any such amendment or repeal to the Company's shareholders at the next meeting of shareholders, and the shareholders may confirm, reject or amend the amendment or repeal.

Meetings of Shareholders

The OBCA requires the Company to call an annual shareholders' meeting not later than 15 months after holding the last preceding annual meeting and permits the Company to call a special shareholders' meeting at any time. In addition, in accordance with the OBCA, the holders of not less than 5% of the Company's shares carrying the right to vote at a meeting sought to be held may requisition our directors

to call a special shareholders' meeting for the purposes stated in the requisition. The Company is required to mail a notice of meeting and management information circular to registered shareholders not less than 21 days and not more than 50 days prior to the date of any annual or special shareholders' meeting. These materials also are filed with Canadian securities regulatory authorities and the SEC. The Company's by-laws provide that a quorum of two shareholders in person or represented by proxy holding or representing by proxy not less than 10% of the Company's issued shares carrying the right to vote at the meeting is required to transact business at a shareholders' meeting. Shareholders, and their duly appointed proxies and corporate representatives, as well as the Company's auditors, are entitled to be admitted to the Company's annual and special shareholders' meetings.

Authorized Capital

The Company's authorized capital consists of an unlimited number of shares of one class designated as common shares. The Company may not create any class or series of shares or make any modification to the provisions attaching to the Company's common shares without the affirmative vote of two-thirds of the votes cast by the holders of the common shares. The Company's common shares do not have pre-emptive rights to purchase additional shares.

Disclosure of Share Ownership

The Securities Act (Ontario) provides that a person or company that beneficially owns, directly or indirectly, voting securities of an issuer or that exercises control or direction over voting securities of an issuer or a combination of both, carrying more than 10% of the voting rights attached to all the issuer's outstanding voting securities (an "insider") must, within 5 days of becoming an insider, file a report in the required form effective the date on which the person became an insider, disclosing any direct or indirect beneficial ownership of, or control or direction over, securities of the reporting issuer. The Securities Act (Ontario) also provides for the filing of a report by an insider of a reporting issuer who acquires or transfers securities of the issuer. This report must be filed within 5 days after the end of the month in which the acquisition or transfer takes place.

The Securities Act (Ontario) also provides that a person or company that acquires (whether or not by way of a take-over bid, issuer bid or offer to acquire) beneficial ownership of voting or equity securities or securities convertible into voting or equity securities of a reporting issuer that, together with previously held securities brings the total holdings of such holder to 10% or more of the outstanding securities of that class, must (a) issue and file forthwith a news release containing the prescribed information and (b) file a report within two business days containing the same information set out in the news release. The acquiring person or company must also issue a press release and file a report each time it acquires an additional 2% or more of the outstanding securities of the same class and every time there is a "material change" to the contents of the news release and report previously issued and filed.

The rules in the United States governing the ownership threshold above which shareholder ownership must be disclosed are more stringent than those discussed above. Section 13 of the Securities Exchange Act of 1934, as amended (the "Exchange Act") imposes reporting requirements on persons who acquire beneficial ownership (as such term is defined in Rule 13d-3 under the Exchange Act) of more than 5% of a class of an equity security registered under Section 12 of the Exchange Act. In general, such persons must file, within 10 days after such acquisition, a report of beneficial ownership with the SEC containing the information prescribed by the regulations under Section 13 of the Exchange Act. This information is also required to be sent to the issuer of the securities and to each exchange where the securities are traded.

Restrictions on Share Ownership by Non-Canadians

There are no limitations under the laws of Canada or in the constitutive documents of the Company on the right of foreigners to hold or vote securities of the Company, except that the Investment Canada Act may require review and approval by the Minister of Industry (Canada) of certain acquisitions of "control" of the Company by a "non-Canadian". The threshold for acquisitions of control is generally defined as being one-third or more of the voting shares of the Company. "Non-Canadian" generally means an individual who is not a Canadian citizen, or a corporation, partnership, trust or joint venture that is ultimately controlled by non-Canadians.

The Company currently has only one material contract. On June 29, 2012, the Company signed a settlement agreement to dispose of its indirect interest in the Israeli Project as more fully described under Item 4(B) of this report.

(D) EXCHANGE CONTROLS

There are currently no laws, decrees, regulations or other legislation in Canada that restricts the export or import of capital or that affects the remittance of dividends, interest or other payments to non-resident holders of our securities other than withholding tax requirements. There is no limitation imposed by

Canadian law or by our Articles of Incorporation or our other organizational documents on the right of a non-resident of Canada to hold or vote our common shares, other than as provided in the North American Free Trade Agreement Implementation Act (Canada) and in the Investment Canada Act, as amended by the World Trade Organization Agreement Implementation Act.

The Investment Canada Act requires notification and, in certain cases, advance review and approval by the Government of Canada of the acquisition by a “non-Canadian” of “control of a Canadian business”, all as defined in the Investment Canada Act. Generally, the threshold for review will be higher in monetary terms, and in certain cases an exemption will apply, for an investor ultimately controlled by persons who are nationals of a WTO Member or have the right of permanent residence in relation thereto.

(E) TAXATION

Canadian Federal Income Tax Consequences

We consider that the following summary fairly describes the principal Canadian federal income tax consequences applicable to a holder of our common shares who at all material times deals at arm’s length with our company, who holds all common shares as capital property, who is resident in the United States, 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 our company in connection with carrying on a business in Canada (a “non-resident holder”). It is assumed that the common shares will at all material times be listed on a stock exchange that is prescribed for purposes of the Income Tax Act (Canada) (the “ITA”) and regulations thereunder. Investors should be aware that the Canadian federal income tax consequences applicable to holders of our common shares will change if, for any reason, we cease to be listed on a prescribed stock exchange. Accordingly, holders and prospective holders of our common shares should consult with their own tax advisors with respect to the income tax consequences of them purchasing, owing and disposing of our common shares should we cease to be listed on a prescribed stock exchange.

This summary is based upon the current provisions of the ITA, the regulations there under, the Canada-United States Tax Convention as amended by the Protocols thereto (the “Treaty”) as at the date of the registration statement and the currently publicly announced administrative and assessing policies of the Canada Revenue Agency (the “CRA”). This summary does not take into account Canadian provincial income tax consequences. This description is not exhaustive of all possible Canadian federal income tax consequences and does not take into account or anticipate any changes in law, whether by legislative, governmental or judicial action. This summary does, however, take into account all specific proposals to amend the ITA and regulations there under, publicly announced by the Government of Canada to the date hereof.

This summary does not address potential tax effects relevant to our company or those tax considerations that depend upon circumstances specific to each investor. Accordingly, holders and prospective holders of our common shares should consult with their own tax advisors with respect to the income tax consequences to them of purchasing, owning and disposing of common shares in our company.

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 of 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.

Article X of the Treaty as amended by the US-Canada Protocol ratified on November 9, 1995 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 Treaty 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

A non-resident holder is not subject to tax under the ITA in respect of a capital gain realized upon the disposition of one of our shares unless the share represents “taxable Canadian property” to the holder thereof. Our common shares will be considered taxable Canadian property to a non-resident holder only if-.

(a) the non-resident holder;

(b) persons with whom the non-resident holder did not deal at arm’s length - or

owned not less than 25% of the issued shares of any class or series of our company at any time during the five year period preceding the disposition. In the case of a non-resident holder to whom shares of our company represent taxable Canadian property and who is resident in the United States, no Canadian taxes will generally be payable on a capital gain realized on such shares by reason of the Treaty unless:

(a) the value of such shares is derived principally from real property (including resource property) situated in Canada,

(b) the holder was resident in Canada for 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 a resident of Canada,

(c) they formed part of the business property or were otherwise effectively connected with a permanent establishment or fixed base that the holder has or bad 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 general 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. This summary does not address the U.S. federal alternative minimum, U.S. federal estate and gift, U.S. state and local, and 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. federal income, U.S. state and local, and foreign tax consequences of the acquisition, ownership, and disposition of Common Shares.

No legal opinion from U.S. legal counsel or ruling from the Internal Revenue Service (“IRS”) has been requested, or will be obtained, regarding the U.S. federal income tax consequences of the acquisition, ownership, and disposition of Common Shares. This summary is not binding on the IRS, and the IRS is not precluded from taking a position that is different from, and contrary to, the positions taken in this summary. In addition, because the authorities on which this summary is based on subject to various interpretations, the IRS and the U.S. courts could disagree with one or more of the conclusions described in this summary.

Scope of this Summary

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 (the “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 or prospective 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 or prospective 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 income, 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 and Tax Consequences Other than U.S. Federal Income Tax 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, but not limited to, 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 transaction, 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; (i) U.S. Holders who are U.S. expatriates or former long-term residents of the United States.; or (j) U.S. Holders that own (directly, indirectly, or by attribution) 10% or more of the total combined voting power of the outstanding shares of the Company. 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 income, 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 a 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.

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 foreign income tax withheld from such distribution) to the extent of the current or accumulated “earnings and profits” of the Company. To the extent that a distribution exceeds the current and accumulated “earnings and profits” of the Company, 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). However, the Company may not maintain the calculations of earnings and profits in accordance with U.S. federal income tax principles, and each U.S. Holder should therefore assume that any distributions by the Company with respect to the Common Shares will constitute ordinary dividend income. Dividends received on common shares generally will not constitute qualified dividend income eligible for the “dividends received deduction.”

Reduced Tax Rates for Certain Dividends

A dividend paid by the Company generally will be taxed at the preferential tax rates applicable to long-term capital gains if (a) the Company is 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.” The Company generally will be a “qualified foreign corporation” under Section 1(h)(11) of the Code (a “QFC”) if (a) the Company is eligible for the benefits of the Canada-U.S. Tax Convention, or (b) the Common Shares are readily tradable on an established securities market in the U.S. However, even if the Company satisfies one or more of such requirements, the Company will not be treated as a QFC if the Company is a “passive foreign investment Company” (or “PFIC”, as defined below) for the taxable year during which the Company pays a dividend or for the preceding taxable year. Even if the Company satisfies one or more of such requirements, as noted below, there can be no assurance that the Company will not become a PFIC. Thus, there can be no assurance that the Company will qualify as a QFC. See “Passive Foreign Investment Company Rule” section below.

The Company has not made the determination of whether it was a “passive foreign investment Company” for the tax year ended March 31, 2013, nor whether it will be a “passive foreign investment Company” for future periods. (See more detailed discussion under “Passive Foreign Investment Company Rule” below). If the Company is not a QFC, a dividend paid by the Company to a U.S. Holder, including a U.S. Holder that is an individual, estate, or trust, generally will be taxed at the 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 who 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 unless the gain is subject to tax in Canada and resourced as “foreign source” under the U.S.-Canada Tax Convention and the U.S. Holder elects to treat such gain as “foreign source”.

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 are subject to significant limitations under the Code.

The amount realized on a sale or other disposition of Common Shares for an amount in foreign currency will generally be the U.S. dollar value of this amount on the date of sale or disposition. On the settlement date, the U.S. Holder will recognize U.S. source foreign currency gain or loss (taxable as ordinary income or loss) equal to the difference (if any) between the U.S. dollar value of the amount received based on the exchange rates in effect on the date of sale or other disposition and the settlement date.

Foreign Tax Credit

A U.S. Holder that 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.” Generally, dividends paid by a foreign corporation should be treated as foreign source income and categorized as “passive income” for this purpose. Gains recognized on the sale of stock of a foreign corporation by a U.S. Holder should be treated as U.S. sources for this purpose, except as otherwise provided in an applicable income tax treaty, and if an election is properly made under the Code. However, the amount of a distribution with respect to the Common Shares that is treated as a “dividend” may be lower for U.S. federal income tax purposes than it is for Canadian federal income tax purposes, resulting in a reduced foreign tax credit allowance to a U.S. Holder. In addition, this limitation is calculated separately with respect to specific categories of income. 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 and Backup Withholding Tax

Under U.S. federal income tax law and Treasury Regulations, certain categories of U.S. Holder must file information returns with respect to their investment in, or involvement in, a foreign corporation. For example, U.S. return disclosure obligations (and related penalties) are imposed on individuals who are U.S. Holders that hold certain specified foreign financial assets in excess of $50,000. The definition of specified foreign financial assets include not only financial accounts maintained in foreign financial institutions, but also, unless held in accounts maintained by a financial institution, any stock or security issued by a non-U.S. person, any financial instrument or contract held for investment that has an issuer or counterparty other than a U.S. person and any interest in a foreign entity. U.S. Holder may be subject to these reporting requirements unless their common shares are held in an account at a domestic financial institution. Penalties for failure to file certain of these information returns are substantial. U.S. Holders should consult with their own tax advisors regarding the requirements of filing information returns, including the requirement to file an IRS Form 8938.

Payments made within the U.S., or by a U.S. payer or U.S. middleman, of dividends on, or proceeds arising from the sale or other taxable disposition of, Common Shares generally will be subject to information reporting and backup withholding tax, at the rate of 28% (increasing to 31% for payments made after December 31, 2012), 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 in a timely manner. Each U.S. Holder should consult its own financial advisor, legal counsel, or accountant regarding the information reporting and backup withholding tax rules.

Passive Foreign Investment Company Rule

If the Company is a “passive foreign investment Company” (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.

The Company generally will be a “passive foreign investment Company” under Section 1297 of the Code (a “PFIC”) if, for a tax year, (a) 75% or more of the gross income of the Company for such tax year is passive income or (b) 50% or more of the assets held by the Company 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 the Company is not publicly traded and either is a “controlled foreign corporation” or makes an election). “Gross income” generally includes all sales revenues less the cost of goods sold, plus income from investments and from incidental or outside operations or sources, and “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. Active business gains arising from the sale of commodities generally are excluded from passive income if substantially all (85% or more) of a foreign corporation’s commodities are stock in trade or inventory, depreciable property used in a trade or business or supplies regularly used or consumed in a trade or business and certain other requirements are satisfied.

For purposes of the PFIC income test and asset test described above, if the Company owns, directly or indirectly, 25% or more of the total value of the outstanding shares of another foreign corporation, the Company 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 the Company 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.

In any year in which the Company is classified as a PFIC, such holder will be required to file an annual report with the IRS containing such information as Treasury Regulations and/or other IRS guidance may require. U.S. Holders should consult their own tax advisors regarding the requirements of filing such information returns under these rules, including the requirement to file an IRS Form 8621.

In addition, if the Company is a PFIC and owns shares of another foreign corporation that also is a PFIC, under certain indirect ownership rules, a disposition of the shares of such other foreign corporation or a distribution received from such other foreign corporation generally will be treated as an indirect disposition by a U.S. Holder or an indirect distribution received by a U.S. Holder, subject to the rules of Section 1291 of the Code discussed below. To the extent that gain recognized on the actual disposition by a U.S. Holder of Common shares or income recognized by a U.S. Holder on an actual distribution received on Common Shares was previously subject to U.S. federal income tax under these indirect ownership rules, such amount generally should not be subject to U.S. federal income tax.

If the Company is 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.”

Under Section 1291 of the Code, any gain recognized on the sale or other taxable disposition of Common Shares, and any “excess distribution” (as defined below) 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. An “excess distribution” as defined in Section 1291(b) of the Code is the excess of distributions with respect to the common shares received by a U.S. Holder in any tax year over 125% of the average annual distribution such U.S. Holder has received from the Company during the shorter of the three preceding tax years, or such 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 Common Shares generally 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.

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 generally 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. 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 the Company is a PFIC, regardless of whether such amounts are actually distributed to such U.S. Holder by the Company.

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. A U.S. Holder may make a Mark-to-Market Election only if the Common Shares are “marketable stock” (as defined in Section 1296(e) of the Code). A U.S. Holder that makes a Mark-to-Market Election will include in gross income, for each taxable year in which the Company is 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, subject to certain limitations, be allowed a deduction in an amount equal to the excess, if any, of (a) such U.S. Holder’s adjusted tax basis in the Common Shares over (b) the fair market value of such Common Shares as of the close of such taxable year.

The determination of whether the Company was, or will be, a PFIC for a taxable year depends, in part, on the application of complex U.S. federal income tax rules, which are subject to differing interpretations, as well as the assets and income of the Company over the course of future taxable years, which cannot be predicted with certainty as of the date of this Annual Report.

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.

Additional Tax on Passive Income

For tax years beginning after March 31, 2013, certain individuals, estates and trusts whose income exceeds certain thresholds will be required to pay a 3.8% Medicare surtax on “net investment income” including, among other things, dividends and net gain from disposition of property (other than property held in a trade or business). U.S. Holders should consult with their tax advisors regarding the effect, if any of this tax on their ownership and disposition of Common Shares.

ITEM 11 – QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The Company is exposed in varying degrees to a number of risks arising from financial instruments. Management’s close involvement in the operations allows for the identification of risks and variances from expectations. The Company does not participate in the use of financial instruments to mitigate these risks and has no designated hedging transactions. The Board approves and monitors the risk management processes. The Board’s main objectives for managing risks are to ensure liquidity, the fulfilment of

obligations, the continuation of the Company’s search for new business participation opportunities, and limited exposure to credit and market risks while ensuring greater returns on the surplus funds on hand. There were no changes to the objectives or the process from the prior year.

A summary of the Company’s risk exposures as it relates to financial instruments are reflected below:

1)	Fair value of financial instruments

The Company’s financial assets and liabilities are comprised of cash, amounts receivable, prepaid expenses, accounts payable and accrued liabilities.

The Company classifies the fair value of these transactions according to the following fair value hierarchy based on the amount of observable inputs used to value the instrument:

•	Level 1 – Values are based on unadjusted quoted prices available in active markets for identical assets or liabilities as of the reporting date.

•	Level 2 – Values are based on inputs, including quoted forward prices for commodities, time value and volatility factors, which can be substantially observed or corroborated in the marketplace. Prices in Level 2 are either directly or indirectly observable as of the reporting date.

•	Level 3 – Values are based on prices or valuation techniques that are not based on observable market data.

Assessment of the significance of a particular input to the fair value measurement requires judgment and may affect the placement within the fair value hierarchy.

The Company’s financial instruments are exposed to certain financial risks: credit risk, liquidity risk, other price risk and market risk.

2) Credit risk

Credit risk is the risk of loss associated with a counter-party’s inability to fulfil its payment obligations. The credit risk is attributable to various financial instruments, as noted below. The credit risk is limited to the carrying value amount carried on the statement of financial position.

a.	Cash– Cash is held with a major international financial institution in Canada and therefore the risk of loss is minimal. However, the Company does have a concentration risk since all funds are held with one bank.

b.	Other receivable – The Company is not exposed to major credit risk attributable to customers. A significant portion of this amount is due from the Canadian government.

3) Liquidity risk

Liquidity risk is the risk that the Company will encounter difficulty in satisfying financial obligations as they become due.

The Company’s approach to managing liquidity is to ensure, as far as possible, that it will have sufficient liquidity to meet its liabilities when due, under both normal and stressed conditions without incurring unacceptable losses or risking harm to the Company’s reputation. The Company holds sufficient cash to satisfy obligations under accounts payable and accruals.

The Company monitors its liquidity position regularly to assess whether it has the funds necessary to take care of its operating needs and needs for investing in new projects. The company has changed its business focus from oil and gas to biotechnology as explained in Note 1 and has signed a letter of intent to acquire a biotech corporation. The Company believes that its existing cash will allow it to finance the drug development work after the acquisition apart from meeting its operational needs at least for another year. However, the exact need for additional cash cannot be reasonably ascertained at this stage. Should the Company require further funding, it intends to secure through equity financing.

However, as a biotech company at an early stage of development and without significant internally generated cash flows, there are inherent liquidity risks, including the possibility that additional financing may not be available to the Company, or that actual drug development expenditures may exceed those planned. The current uncertainty in global markets could have an impact on the Company’s future ability to access capital on terms that are acceptable to the Company. There can be no assurance that required financing will be available to the Company.

4) Market risk

Market risk consists of interest rate risk and foreign currency risk. The Company is exposed to foreign currency risk since almost its entire cash holding is in US Dollars.

ITEM 15 - CONTROLS AND PROCEDURES

a) Evaluation of Disclosure controls and procedures

We have only one employee. Our Chief Financial Officer who, until June 4, 2013, also served as Chief Executive 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, until June 4, 2013, comprised two independent directors. We therefore did 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 Company to ensure proper and complete disclosure of material information. The limited number of consultants and direct involvement of the CEO and CFO 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.

As at March 31, 2013, the management carried out a comprehensive review and update of the internal controls existing over the financial reporting. Mitigating controls and procedures were identified wherever possible. Some controls were implemented as a secondary detection mechanism if the initial controls failed to prevent errors from occurring.

However, effective June 4, 2013, we appointed a new chief executive officer and so the management functions have been segregated between chief executive officer and chief financial officer. Further, the audit committee has now been expanded to include three members – two independent directors and the chief financial officer.

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

Management of Bontan Corporation Inc. (The Company) is responsible for establishing and maintaining adequate internal control over financial reporting. The Company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of the Company’s consolidated financial statements for external reporting purposes in accordance with generally accepted accounting principles.

The Company’s internal control over financial reporting includes policies and procedures that:

-	Pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect transactions and dispositions of assets;

Provide reasonable assurance that transactions are recorded as necessary to permit preparation of consolidated financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures are being made only in accordance with authorizations of management and the Directors of the Company: and,

-	Provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the Company’s assets that could have a material effect on the Company’s consolidated financial statements.

Due to its inherent limitations, internal control over financial reporting may not prevent or detect misstatements on a timely basis. Also, projections of any evaluation of the effectiveness of internal control over financial reporting are subject to the risks that the controls may become inadequate because of changes in conditions or that the degree of compliance with the policies or procedures may deteriorate.

Management evaluated and updated the design and operation of the Company’s internal control over financial reporting as of March 31, 2013, based on the framework and criteria established in Internal Control – Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission and has concluded that such internal control over financial reporting is effective.

There was a lack of segregation of duties since Chief executive and financial officer handled accounting records and was also a sole signatory to bank accounts. However, effective June 4, 2013, we appointed a new CEO and segregated management functions between the CEO and CFO. Further, we also introduced dual signatories to all our bank accounts and independent review of bank reconciliations and other related controls. Our audit committee – now known as audit and compensation committee - now comprise three members two of whom are independent.

We believe that the above changes have mitigated significantly any potential risks arising from the earlier weakness of lack of segregation of duties.

c) Attestation report of the registered public accounting firm

Not applicable since we are neither an accelerated filer nor a large accelerated filer as defined in Rule 12b-2 under the Securities Exchange Act of 1934.

d) Changes in Internal Controls

There were no changes in our internal control over financial reporting that occurred during the year ended March 31, 2013 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. However, as explained under b) above, we have now introduced segregation of duties and significantly addressed certain deficiencies in the internal control arising from lack of segregation.

ITEM 16(A) AUDIT COMMITTEE FINANCIAL EXPERTS

Our Board of Directors has determined that majority of the members of our Audit Committee are “independent” within the meaning of applicable Commission regulations and the listing standards of the NASDAQ Stock Market, Inc. (“NASDAQ”). In addition, the Board of Directors has determined that Mr. James Mellon is an audit committee financial expert within the meaning paragraph (b) of Item 16A of Form 20-F under the Exchange Act.

The Commission has indicated that the designation of a person as an audit committee financial expert does not make such person an “expert” for any purpose, impose any duties, obligations or liability on such person that are greater than those imposed on members of the Audit Committee and the Board of Directors who do not carry this designation or affect the duties, obligations or liability of any other member of the Audit Committee or the Board of Directors.

ITEM 16 (B) CODES OF ETHICS

We have adopted a Code of Ethics, which applies to all employees, consultants, officers and directors. A copy of our current code of ethics was included in the exhibits to the annual report for the fiscal year ended March 31, 2007 (Exhibit Item 19(b) 11).

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Shareholders of Bontan Corporation Inc.

We have audited the accompanying consolidated financial statements of Bontan Corporation Inc., which comprise the consolidated statements of financial position as at March 31, 2013 and March 31, 2012, and the consolidated statements of operations and comprehensive loss, changes in shareholders’ equity and cash flows for the years ended March 31, 2013, 2012 and 2011 and a summary of significant accounting policies and other explanatory information.

Management's Responsibility for the Consolidated Financial Statements

Management is responsible for the preparation and fair presentation of these consolidated financial statements in accordance with International Financial Reporting Standards as issued by the International Accounting Standards Board, and for such internal control as management determines is necessary to enable the preparation of consolidated financial statements that are free from material misstatement, whether due to fraud or error.

Auditor’s Responsibility

Our responsibility is to express an opinion on these consolidated financial statements based on our audits. We conducted our audits in accordance with Canadian generally accepted auditing standards and the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we comply with ethical requirements and plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free from material misstatement. We were not engaged to perform an audit of the Company’s internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion.

An audit involves performing procedures to obtain audit evidence about the amounts and disclosures in the consolidated financial statements. The procedures selected depend on the auditor’s judgment, including the assessment of the risks of material misstatement of the consolidated financial statements, whether due to fraud or error. An audit also includes evaluating the appropriateness of accounting policies used and the reasonableness of accounting estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements.

We believe that the audit evidence we have obtained in our audits is sufficient and appropriate to provide a basis for our audit opinion.

Opinion

In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of Bontan Corporation Inc. as at March 31, 2013 and March 31, 2012, and its financial performance and its cash flows for the years ended March 31, 2013, 2012 and 2011 in accordance with International Financial Reporting Standards as issued by the International Accounting Standards Board.

Israel Oil & Gas Company, a wholly owned subsidiary, was merged with the Company on May 15, 2012.

All inter-company balances and transactions have been eliminated on consolidation.

The consolidated financial statements are presented in Canadian dollars which is also the functional currency of the Company and its subsidiaries.

(d) Use of Estimates and judgments

The preparation of consolidated financial statements in conformity with IFRS requires management to make judgments, estimates and assumptions that affect the application of accounting policies and the reported amounts of assets, liabilities, income and expenses. Actual results may differ from these estimates.

Estimates and underlying assumptions are reviewed on an ongoing basis. Revisions to accounting estimates are recognized in the year in which the estimates are revised and in any future years affected. Significant areas where estimation uncertainty and critical judgments are applied include valuation of financial instruments, valuation of property, plant and equipment, impairment losses, depletion and depreciation, and measurement of share- based compensation.

3.	SIGNIFICANT ACCOUNTING POLICIES

The accounting policies set out below have been applied consistently to all years presented in these consolidated financial statements, and have been applied consistently by the Company and its subsidiaries.

Financial instruments

Financial assets

All financial assets are initially recorded at fair value and are designated upon inception into one of the following four categories: held-to-maturity, available-for-sale, loans and receivables or at fair value through profit or loss (“FVTPL”).

Financial assets classified as FVTPL are measured at fair value with unrealized gains and losses recognized through earnings. The Company’s cash is classified as FVTPL.

Financial assets classified as loans and receivables are measured at amortized cost. The Company’s trade and other receivables are classified as loans and receivables.

Short term investments which consist of marketable securities are designated as “available-for-sale” and are measured at fair value with unrealized gains and losses recorded in other comprehensive income until the security is sold, or if an unrealized loss is considered other than temporary.

The purchase or sale of financial assets that require delivery of assets within a time frame established by regulation or convention in the marketplace (regular way trades) are recognized on the settlement date.

Common shares are classified as equity. Incremental costs directly attributable to the issue of common shares and stock options are recognized as a deduction from equity, net of any tax effects.

Transactions costs associated with FVTPL financial assets are expensed as incurred, while transaction costs associated with all other financial assets are included in the initial carrying amount of the asset.

Financial liabilities

All financial liabilities are initially recorded at fair value and designated upon inception as FVTPL or other financial liabilities.

Financial liabilities classified as other financial liabilities are initially recognized at fair value less directly attributable transaction costs. After initial recognition, other financial liabilities are subsequently measured at amortized cost using the effective interest method. The effective interest method is a method of calculating the amortized cost of a financial liability and of allocating interest expense over the relevant period. The effective interest rate is the rate that exactly discounts estimated future cash payments through the expected life of the financial liability, or, where appropriate, a shorter period. The Company’s trade and other payables are classified as other financial liabilities.

Impairment of financial assets

The Company assesses at each date of the statement of financial position whether a financial asset is impaired.

Assets carried at amortized cost

If there is objective evidence that an impairment loss on assets carried at amortized cost has been incurred, the amount of the loss is measured as the difference between the asset’s carrying amount and the present value of estimated future cash flows discounted at the financial asset’s original effective interest rate. The carrying amount of the asset is then reduced by the amount of the impairment. The amount of the loss is recognized in profit or loss.

If, in a subsequent period, the amount of the impairment loss decreases and the decrease can be related objectively to an event occurring after the impairment was recognized, the previously recognized impairment loss is reversed to the extent that the carrying value of the asset does not exceed what the amortized cost would have been had the impairment not been recognized. Any subsequent reversal of an impairment loss is recognized in profit or loss.

In relation to trade receivables, a provision for impairment is made and an impairment loss is recognized in profit and loss when there is objective evidence (such as the probability of insolvency or significant financial difficulties of the debtor) that the Company will not be able to collect all of the amounts due under the original terms of the invoice. The carrying amount of the receivable is reduced through use of an allowance account. Impaired debts are written off against the allowance account when they are assessed as uncollectible.

If an available-for-sale asset is impaired, an amount comprising the difference between its cost and its current fair value, less any impairment loss previously recognized in profit or loss, is transferred from equity to profit or loss. Reversals in respect of equity instruments classified as available-for-sale are not recognized in profit or loss.

Foreign currency translation

The functional and presentation 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.

Share-based payments

The Company accounts for share-based payments granted to directors, officers, employees and consultants using the Black-Scholes option-pricing model to determine the fair value of the plan at grant date. An estimated forfeiture rate is incorporated into the fair value calculated and adjusted to reflect the actual number of options that vest. Share-based payments are recorded and reflected as an expense over the vesting period with a corresponding amount reflected in stock option reserve. At exercise, the associated amounts previously recorded in stock option reserve are transferred to common share capital.

The quoted market price of the Company’s shares on the date of issuance under any share- based plan is considered as fair value of the shares issued.

Accounting for equity units

When the Company issues Units under a private placement comprising of common shares and warrants, the Company follows the relative fair value method of accounting for warrants attached to and issued with common shares of the Company. Under this method, the fair value of warrants issued is estimated using a Black-Scholes option pricing model which is added to fair value of the common shares determined using the stock price at the date of issuance and the percentage relative to the fair values determined. The fair value of the common shares and the warrants are proportionately adjusted to the net proceeds received. The fair value is then related to the total of the net proceeds received on issuance of the Common shares.

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.

Income taxes

Income tax expense comprises current and deferred tax. Income tax expense is recognized in profit or loss except to the extent that it relates to items recognized directly in equity, in which case it is recognized in equity.

Current tax is the expected tax payable on the taxable income for the year, using tax rates enacted or substantively enacted at the reporting date, and any adjustments to tax payable in respect of previous years.

Deferred tax is recognized using the balance sheet method, providing for temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for taxation purposes. Deferred tax is not recognized on the initial recognition of assets or liabilities in a transaction that is not a business combination. In addition, deferred tax is not recognized for taxable temporary differences arising on the initial recognition of goodwill. Deferred tax is measured at the tax rates that are expected to be applied to temporary differences when they reverse, based on the laws that have been enacted or substantively enacted by the reporting date. Deferred tax assets and liabilities are offset if there is a legally enforceable right to offset, and they relate to income taxes levied by the same tax authority on the same taxable entity, or on different tax entities, but they intend to settle current tax liabilities and assets on a net basis or their tax assets and liabilities will be realized simultaneously.

A deferred tax asset is recognized to the extent that it is probable that future taxable profits will be available against which the temporary difference can be utilized. Deferred tax assets are reviewed at each reporting date and are reduced to the extent that it is no longer probable that the related tax benefit will be realized.

Determination of fair value

A number of the Company’s accounting policies and disclosures required the determination of fair value, both for financial and non-financial assets and liabilities. Fair values have been determined for measurement and/or disclosure purposes based on the following methods. When applicable, further information about the assumptions made in determining fair values is disclosed in the notes specific to that asset or liability.

a ) Property, plant and equipment are recognized at fair value in a business combination. The fair value of property, plant and equipment is the estimated amount for which the property, plant and equipment could be exchanged on the acquisition date between a willing buyer and a willing seller in an arm’s length transaction after proper marketing wherein the parties had each acted knowledgeably, prudently and without compulsion. The fair value of oil and natural gas interests (included in property, plant and equipment) is estimated with reference to the discounted cash flows expected to be derived from oil and gas production based on externally prepared reserve reports. The risk-adjusted discount rate is specific to the asset with reference to general market conditions, being 10% for fiscal 2013 (2012 – 10%).

The market value of other items of property, plant and equipment is based on the quoted market prices for similar items.

b) The fair value of cash and cash equivalents, accounts receivable and accruals and accounts payable and accruals is estimated as the present value of future cash flows, discounted at the market rate of interest at the reporting date. At March 31, 2013 and 2012 the fair value of these balances approximated their carrying value due to their short term to maturity.

c) The fair value of stock options is measured using a Black Scholes option pricing model. Measurement inputs include share price on measurement date, exercise price of the instrument, expected volatility (based on weighted average historic volatility adjusted for changes expected due to publicly available information), weighted average expected life of the instruments (based on historical experience and general option holder behavior), expected dividends, and the risk-free interest rate (based on government bonds).

New standards and interpretations not yet adopted

Standards issued but not yet effective up to the date of issuance of the Company‘s consolidated financial statements are listed below. This listing is of standards and interpretations issued which the Company reasonably expects to be applicable at a future date. The Company intends to adopt those standards when they become effective.

IAS 1 – Presentation of Financial Statements

In June 2011, the IASB issued amendments to International Accounting Standard (“IAS”) 1, “Presentation of Financial Statements”. The amendments govern the presentation of Other Comprehensive Income (“OCI”) in the financial statements, primarily by requiring OCI items that may be reclassified to the consolidated statements of earnings to be presented separately from those that remain in equity.

These changes are applicable for fiscal years beginning on or after July 1, 2012. The Company will apply these changes for its first quarter of fiscal year 2014 and does not expect that the adoption of these changes will have a material impact on its consolidated financial statements.

IAS 32 – Financial Instruments Presentation

In December 2011, the IASB issued revised versions of IFRS 7, “Financial Instruments: Disclosures” and IAS 32, “Financial Instruments: Presentation”. The modifications clarify the offsetting rules and state new disclosure requirements for offsetting of financial assets and financial liabilities on the consolidated balance sheets.

The changes applied to IFRS 7 are applicable for fiscal years beginning on or after January 1, 2013 while changes applied to IAS 32 are applicable for fiscal years beginning on or after January 1, 2014. The Company will apply these changes for its first quarters of fiscal years 2014 and 2015 respectively and does not expect that the adoption of these changes will have a material impact on its consolidated financial statements.

IFRS 9 ‐ Financial Instruments

The IASB intends to replace IAS 39, Financial Instruments: Recognition and Measurements, with IFRS 9, Financial Instruments. IFRS 9 will be published in six phases, of which the first phase has been published.

For financial assets, IFRS 9 uses a single approach to determine whether a financial asset is measured at amortized cost or fair value, and replaces the multiple rules in IAS 39. The approach in IFRS 9 is based on how an entity manages its financial instruments in the context of its business model and the contractual cash flow characteristics of the financial assets. The new standard also requires a single impairment method to be used. For financial liabilities, the approach to the fair value option may require different accounting for changes to the fair value of a financial liability as a result of changes to an entity’s own credit risk.

IFRS 9 is effective for annual periods beginning on April 1, 2015, but is available for early adoption. The Company has yet to assess the full impact of IFRS 9.

IFRS 10 – Consolidated Financial Statements

As of April 1, 2013, the Company will be required to adopt IFRS 10 which requires an entity to consolidate an investee when it is exposed, or has rights, to variable returns from its involvement with the investee and has the ability to affect those returns through its power over the investee. Under existing IFRS, consolidation is required when an entity has the power to govern the financial and operating policies of an entity so as to obtain benefits from its activities. IFRS 10 replaces SIC‐12 – Consolidation – Special Purpose Entities, and parts of IAS 27 –Consolidated and Separate Financial Statements. IFRS 10 is effective for annual periods beginning on April 1, 2013, but is available for early adoption. The Company has yet to assess the full impact of IFRS 10.

IFRS 11 – Joint Arrangements

As of April 1, 2013, the Company will be required to adopt IFRS 11 which requires a venturer to classify its interest in a joint arrangement as a joint venture or joint operation. Joint ventures will be accounted for using the equity method of accounting whereas for a joint operation the venturer will recognize its share of the assets, liabilities, revenue and expenses of the joint operations. Under existing IFRS, entities have the choice to proportionately consolidate or equity account for interests in joint ventures. IFRS 11 supersedes IAS 31 –Interests in Joint Ventures, and SIC 13 – Jointly Controlled Entities – Non‐monetary Contributions by Venturers. IFRS 11 is effective for annual periods beginning on April 1, 2013, but is available for early adoption. The Company has yet to assess the full impact of IFRS 11.

IFRS 12 – Disclosure of Interests in Other Entities

As of April 1, 2013, the Company will be required to adopt IFRS 12 which establishes disclosure requirements for interests in other entities, such as joint arrangements, associates, special purpose vehicles and off balance sheet vehicles. The standard carries forward existing disclosures and also introduces significant additional disclosure requirements that address the nature of, and risks associated with, an entity’s interests in other entities. IFRS 12 is effective for annual periods beginning on April 1, 2013, but is available for early adoption. The Company has yet to assess the full impact of IFRS 12.

IFRS 13 – Fair Value Measurement

As of April 1, 2013, the Company will be required to adopt IFRS 13, a comprehensive standard for fair value measurement and disclosure requirements for use across all IFRS standards. This new standard clarifies that fair value is the price that would be received to sell an asset, or paid to transfer a liability in an orderly transaction between market participants, at the measurement date. It also establishes disclosures about fair value measurement. Under existing IFRS, guidance on measuring and disclosing fair value is dispersed among the specific standards requiring fair value measurements and in many cases does not reflect a clear measurement basis or consistent disclosures. IFRS 13 is effective for annual periods beginning on April 1, 2013, but is available for early adoption. The Company has yet to assess the full impact of IFRS 13.

IAS 28 – Investments in Associates and Joint Ventures

IAS 28, Investments in Associates and Joint Ventures prescribes the accounting for investments in

associates and sets out the requirements for the application of the equity method when accounting for investments in associates and joint ventures. IAS 28 applies to all entities that are investors with joint control of, or significant influence over, an investee (associate or joint venture). This standard is effective for annual periods beginning on April 1, 2013, with early application permitted. The Company has yet to assess the full impact of IFRS 28.

5. EXPLORATION AND EVALUATION EXPENDITURES RECOVERABLE

The Company held an indirect 4.70% interest in two offshore drilling licenses in Israel (“Israeli project”) through its 76.79% equity of IPC Cayman.

The Company signed a settlement agreement on December 15, 2011 to dispose of its interest in the Israeli project held through its ownership of 76.79% equity in IPC Cayman. The agreement being extended, from time to time, and amended, was finally closed on June 29, 2012.

As per the terms of the revised settlement agreement the Company received US$5 million and surrendered all its shares in IPC Cayman for cancellation. The Company and IPC Parties exchanged mutual releases and dismissed all lawsuits against each other and against IPC Oil and Gas Holdings Ltd. (formerly, Shaldieli Ltd.) and certain of its promoters. The Company also received an extension fee of US$100,000 which has been included as other income.

As a result of the above settlement and cancellation of previously issued warrants in connection with the Israeli project, valued at $492,516, the Company had a net recovery of 230,455 as follows:

0.35	42,825,000	1.90
0.29	66,071,420	1.59

9. LOSS PER SHARE

Loss per share is calculated on the weighted average number of common shares outstanding during the year, which was 80,403,243 (2012 - 78,680,743, 2011: 78,469,909).

The Company had approximately 66 million (2012: 68 million, 2011: 73 million) warrants and 5.4 million options (2012: 5.4 million, 2011: 5.8 million), which were not exercised as at March 31, 2013. 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.	CONSULTING FEES

	2013	2012	2011
Fees settled in stocks and options	$ 179,141	$ 7,171	$ 273,043

	$ 741,159	$ 432,607	$ 778,899

11.	INCOME TAXES

Income tax expense differs from the amount that would be computed by applying the Federal and Provincial statutory income tax rates to income (loss) before income taxes. The components of these differences are estimated as follows:

		2013	2012	2011
Income tax recovery based on combined corporate income tax rate of 26.50% (2012: 25%)		$(390,033)	$(617,595)	$(889,551)

Provision for income taxes		$-	$-	$-

The components of the temporary differences and the country of origin at March 31, 2013 and 2012 are as follows (applying the combined Canadian federal and provincial statutory income tax rate of 26.5% and the US income tax rate of 34%). No deferred tax assets are recognized on these differences as it is not probable that sufficient taxable profit will be available to realize such assets

The Company has approximately $18.9 million (2012: $12.6 million) in Canadian non-capital losses, $4.0 million (2012: $4.8 million) in capital losses and US$ 4.4 million (2011: US$4.4 million) in US non-capital losses available to claim against future taxable income. The benefits arising from these losses has not been included in the consolidated financial statements as management has determined that it is not more likely than not that the losses will be utilized.

The non-capital losses expire as follows:

12. COMMITMENTS AND CONTINGENT LIABILITIES

(a)

The Company entered into a consulting contract with Mr Kam Shah, the Chief Executive Officer and Chief Financial Officer on April 1, 2005 for a five-year term. This term was extended by another five years to March 31, 2015 by the audit committee on April 1, 2010. Mr Shah’s monthly fee is $15,000 plus taxes. Further, the contract provides for a lump sum compensation of US$250,000 for early termination of the contract without cause. The contract also provides for entitlement to stock compensation and stock options under appropriate plans as may be decided by the board of directors from time to time.

(b)	There were contingent liabilities and assets as at March 31, 2013 in respect of indemnities undertaken and received as part of the oil and gas activities which have now been discontinued. No material losses or gains are likely to arise from such contingent liabilities and assets.

15. FINANCIAL INSTRUMENTS AND RISK MANAGEMENT

The Company’s financial instruments recognized in the balance sheet consist of the following:

	March 31, 2013		March 31, 2012
	Carrying value	Fair value	Carrying value	Fair value
Financial assets
Cash	3,376,531	3,376,531	58,359	58,359
Other receivable	108,544	108,544	231,039	231,039
Short term investments	-	-	208,100	227,600
Financial liabilities
Accounts payable and accrued liabilities	454,663	454,663	1,040,450	1,040,450

Fair value estimates are made at a specific point in time, based on relevant market information and information about financial instruments. These estimates are subject to and involve uncertainties and matters of significant judgment, therefore cannot be determined with precision. Changes in assumptions could significantly affect the estimates.

A summary of the Company’s risk exposures as it relates to financial instruments are reflected below:

a)	Fair value of financial instruments

The Company’s financial assets and liabilities are comprised of cash, amounts receivable, prepaid expenses, accounts payable and accrued liabilities.

The Company classifies the fair value of these transactions according to the following fair value hierarchy based on the amount of observable inputs used to value the instrument:

• Level 1 – Values are based on unadjusted quoted prices available in active markets for identical assets or liabilities as of the reporting date.

• Level 2 – Values are based on inputs, including quoted forward prices for commodities, time value and volatility factors, which can be substantially observed or corroborated in the marketplace. Prices in Level 2 are either directly or indirectly observable as of the reporting date.

• Level 3 – Values are based on prices or valuation techniques that are not based on observable market data.

Assessment of the significance of a particular input to the fair value measurement requires judgment and may affect the placement within the fair value hierarchy.

The Company’s financial instruments are exposed to certain financial risks: credit risk, liquidity risk, other price risk and market risk.

Credit risk

Credit risk is the risk of loss associated with a counter-party’s inability to fulfill its payment obligations. The credit risk is attributable to various financial instruments, as noted below. The credit risk is limited to the carrying value amount carried on the statement of financial position.

a.	Cash– Cash is held with a major international financial institution in Canada and therefore the risk of loss is minimal. However, the Company does have a concentration risk since all funds are held with one bank.

b.	Other receivable – The Company is not exposed to major credit risk attributable to customers. A significant portion of this amount is due from the Canadian government.

c)	Liquidity risk

Liquidity risk is the risk that the Company will encounter difficulty in satisfying financial obligations as they become due.

Market risk

Market risk consists of interest rate risk and foreign currency risk. The Company is exposed to foreign currency risk, since almost all of its cash holding is in US Dollars.

16. CAPITAL DISCLOSURES

The Company considers the items included in Shareholders’ Equity as capital. The Company had payables of approximately $ 0.4 million as at March 31, 2013 and current assets, mostly in cash of approximately $3.5 million. The Company’s objectives when managing capital are to safeguard the Company’s ability to continue as a going concern in order to pursue new business opportunities and to maintain a flexible capital structure which optimizes the costs of capital at an acceptable risk.

The Company manages the capital structure and makes adjustments to it in light of changes in economic conditions and the risk characteristics of the underlying assets. To maintain or adjust the capital structure, the Company may attempt to issue new shares, issue new debt, acquire or dispose of assets or adjust the amount of cash.

As at March 31, 2013, the shareholders’ equity was approximately $ 3 million (March 31, 2012: $ 4.8 million). Approximately all of it was held in cash (March 31, 2012: $0.3 million or 6%).

The Company is not subject to any externally imposed capital requirements and does not presently utilize any quantitative measures to monitor its capital. There have been no changes to the Company’s approach to capital management during the year ended March 31, 2013.
