Uranium Energy Corp. was incorporated under the laws of the State of Nevada on May 16, 2003 and since 2004, we have been engaged in uranium mining and related activities, including exploration, pre-extraction, extraction and processing on projects located in the United States and Paraguay. In November 2010, we commenced uranium extraction utilizing in-situ recovery for the first time at the Palangana Mine and processed those materials at the Hobson Facility into drums of U₃O₈, our only sales product and source of revenue. We generated revenues from sales of U₃O₈ during Fiscal 2013 and 2012, with no revenues generated prior to Fiscal 2012. We also hold uranium projects in various stages of exploration and pre-extraction in the States of Arizona, Colorado, New Mexico, Texas and Wyoming and in Paraguay.

We have a history of significant negative cash flow and accumulated deficit since inception to October 31, 2013 of $148.6 million, incurring a net loss of $5.9 million for the three months ended October 31, 2013. For Fiscal 2013, 2012 and 2011, we incurred net losses of $21.9 million, $25.1 million and $27.4 million, respectively. Although we generated revenues from sales of uranium concentrates during Fiscal 2013 and 2012 of $9.0 million and $13.8 million, respectively, we have yet to achieve profitability or develop positive cash flow from operations. Furthermore, we do not expect to achieve profitability or develop positive cash flow from operations in the near term, which may never happen. Historically, we have been reliant primarily on equity financings and, more recently, on debt financing to fund our operations and we expect this reliance to continue for the foreseeable future. As a result of our limited financial and operating history, including our significant negative cash flow and net losses to date, it may be difficult to evaluate our future performance.

Our long-term success, including the recoverability of the carrying values of our assets and our ability to acquire additional uranium projects and continue with exploration, pre-extraction and mining activities on our existing uranium projects, will depend ultimately on our ability to achieve and maintain profitability and to develop positive cash flow from our operations by establishing ore bodies that contain commercially recoverable uranium and to develop these into profitable mining activities. The economic viability of our mining activities has many risks and uncertainties including, but not limited to: (i) a significant, prolonged decrease in the market price of uranium; (ii) difficulty in marketing and/or selling uranium concentrates; (iii) significantly higher than expected capital costs to construct the mine and/or processing plant; (iv) significantly higher than expected extraction costs; (v) significantly lower than expected uranium extraction; (vi) significant delays, reductions or stoppages of uranium extraction activities; and (vi) the introduction of significantly more stringent regulatory laws and regulations. Our mining activities may change as a result of any one or more of these risks and uncertainties and there is no assurance that any ore body that we extract mineralized materials from will result in profitable mining activities.

S-8

Our operations are capital intensive, and we will require significant additional financing to acquire additional uranium projects and continue with our exploration and pre-extraction activities which include assaying, drilling, geological and geochemical analysis and mine construction costs. In the absence of such additional financing, we would not be able to fund our operations, including continuing with our exploration and pre-extraction activities, which may result in delay, curtailment or abandonment of any one or all of our uranium projects.

Historically, we have been reliant primarily on equity financings from the sale of our common stock and, more recently, on debt financing to fund our operations. We have filed a Form S-3 "Shelf" Registration Statement that became effective September 2, 2011 which provides for the public offer and sale of certain securities of our Company from time to time, at our discretion, for gross proceeds of up to $50 million, of which approximately $34.4 million has been utilized (approximately $22.5 million pursuant to an offering of shares on April 10, 2012, approximately $7.1 million pursuant to an offering of units consisting of shares and warrants on October 23, 2013, and approximately $4.8 million representing the aggregate exercise price to purchase warrant shares upon exercise of the warrants issued as part of such units, although there is no guarantee that any of such warrants will be exercised), leaving appropriately $15.6 million available. We filed a further registration statement pursuant to Rule 462(b) on December 31, 2013 to register securities representing an additional 20% of such remaining amount, that is, an additional approximately $3.1 million. Such $15.6 million and further $3.1 million (for a total of approximately $18.7 million) will be utilized under the offering contemplated by this prospectus supplement and the accompanying prospectus. We have also entered into a Credit Agreement dated July 30, 2013 which provides for a $20 million secured credit facility, pursuant to which we have drawn down $10 million in principal.

Although we have also generated cash flow from our mining activities during Fiscal 2013 and 2012, our reliance on equity and debt financings is expected to continue for the foreseeable future. We caution that the availability of future financing will be dependent on many factors, including but not limited to general market conditions and the market value of our common stock. We may also be required to seek other forms of financing, such as joint venture arrangements, to continue advancing our uranium projects. A joint venture would depend entirely on our ability to find one or more suitable third parties willing to enter into such an arrangement, and would typically require us to assign a percentage interest in the mineral project to the joint venture participants.

Factors beyond our control such as, but not limited to, volatility in the global financial markets affecting our stock price, the status of the worldwide economy and the market price of uranium may pose significant challenges to our ability to access additional financing, including access to the equity and credit markets. There is no assurance that we will be successful in securing any form of additional financing when required and on terms favorable to us.

Under our $20 million secured credit facility, we received initial funding in the amount of $10 million, with an additional $5 million available for draw-down pursuant to a second advance and a further additional $5 million available for draw-down pursuant to a third advance, in each case in accordance with the terms of a credit agreement. The credit agreement includes restrictive covenants that, among other things, limit our ability to sell the assets securing our indebtedness or to incur additional indebtedness other than permitted indebtedness, which may restrict our ability to pursue certain business strategies from time to time. If we do not comply with these covenants, we could be in default which, if not addressed or waived, could require accelerated repayment of our indebtedness.

Our ability to make scheduled payments depends on our financial condition and operating performance, which are subject to prevailing economic, competitive, legislative and regulatory conditions beyond our control. We may be unable to generate a level of cash flow from operating activities sufficient to permit us to pay the principal, interest and standby fees on our indebtedness.

S-9

If we cannot make scheduled payments on our debt, we will be in default which, if not addressed or waived, could require accelerated repayment of our indebtedness and the enforcement by the lenders against the assets securing our indebtedness. Our credit facility is secured by our Hobson Processing Facility and the Goliad mineral leases, and in the event of the advance of the final $5 million, would be required to be secured by our Palangana mineral leases. These are key assets on which our business is substantially dependent and as such, the enforcement against any one or all of these assets would have a material adverse effect on our operations and financial condition.

Our uranium extraction and sales history is limited, with our uranium extraction originating from a single uranium mine. Our ability to continue generating revenue is subject to a number of factors, any one or more of which may adversely affect our revenues, results of operations and financial condition.

We have a limited history of uranium extraction and generating revenue. In November 2010, we commenced uranium extraction at a single uranium mine, the Palangana Mine, which has been our sole source for the uranium concentrates sold to generate our revenues during Fiscal 2013 and 2012, with no revenues generated prior to Fiscal 2012. Our ability to continue generating revenue from the Palangana Mine is subject to a number of factors which include, but are not limited to, (i) a significant, prolonged decrease in the market price of uranium; (ii) difficulty in marketing and/or selling uranium concentrates; (iii) significantly higher than expected capital costs to construct the mine and/or processing plant; (iv) significantly higher than expected extraction costs; (v) significantly lower than expected uranium extraction; (vi) significant delays, reductions or stoppages of uranium extraction activities; and (vii) the introduction of significantly more stringent regulatory laws and regulations. Furthermore, continued mining activities at the Palangana Mine will eventually deplete the Palangana Mine or become uneconomical, and if we are unable to directly acquire or develop our existing uranium projects into additional uranium mines from which we can commence uranium extraction, it will negatively impact our ability to continue generating revenues. Any one or more of these occurrences may adversely affect our results of operations and financial condition.

Uranium exploration and pre-extraction programs and mining activities are inherently subject to numerous significant risks and uncertainties, many beyond our control, including, but not limited to: (i) unanticipated ground and water conditions and adverse claims to water rights; (ii) unusual or unexpected geological formations; (iii) metallurgical and other processing problems; (iv) the occurrence of unusual weather or operating conditions and other force majeure events; (v) lower than expected ore grades; (vi) industrial accidents; (vii) delays in the receipt of or failure to receive necessary government permits; (viii) delays in transportation; (ix) availability of contractors and labor; (x) government permit restrictions and regulation restrictions; (xi) unavailability of materials and equipment; and (xii) the failure of equipment or processes to operate in accordance with specifications or expectations. These risks and uncertainties could result in: delays, reductions or stoppages in our mining activities; increased capital and/or extraction costs; damage to, or destruction of, our mineral projects, extraction facilities or other properties; personal injuries; environmental damage; monetary losses; and legal claims.

Success in uranium exploration is dependent on many factors, including, without limitation, the experience and capabilities of a company's management, the availability of geological expertise and the availability of sufficient funds to conduct the exploration program. Even if an exploration program is successful and commercially recoverable uranium is established, it may take a number of years from the initial phases of drilling and identification of the mineralization until extraction is possible, during which time the economic feasibility of extraction may change such that the uranium ceases to be economically recoverable. Uranium exploration is frequently non-productive due, for example, to poor exploration results or the inability to establish ore bodies that contain commercially recoverable uranium, in which case the uranium project may be abandoned and written-off. Furthermore, we will not be able to benefit from our exploration efforts and recover the expenditures that we incur on our exploration programs if we do not establish ore bodies that contain commercially recoverable uranium and develop these uranium projects into profitable mining activities, and there is no assurance that we will be successful in doing so for any of our uranium projects.

S-10

Whether an ore body contains commercially recoverable uranium depends on many factors including, without limitation: (i) the particular attributes, including material changes to those attributes, of the deposit such as size, grade, recovery rates and proximity to infrastructure; (ii) the market price of uranium, which may be volatile; and (iii) government regulations and regulatory requirements including, without limitation, those relating to environmental protection, permitting and land use, taxes, land tenure and transportation.

We have established the existence of mineralized materials for certain uranium projects, including the Palangana Mine. We have not established proven or probable reserves, as defined by the SEC under Industry Guide 7, through the completion of a "final" or "bankable" feasibility study for any of our uranium projects, including the Palangana Mine. Furthermore, we have no plans to establish proven or probable reserves for any of our uranium projects for which we plan on utilizing ISR mining, such as the Palangana Mine. Since we commenced uranium extraction at the Palangana Mine without having established proven or probable reserves, there may be greater inherent uncertainty as to whether or not any mineralized material can be economically extracted as originally planned and anticipated. Any mineralized materials established or extracted from the Palangana Mine should not be in any way associated with having established or produced from proven or probable reserves.

Despite the fact that we commenced uranium extraction at the Palangana Mine in November 2010, we remain in the Exploration Stage as defined under Industry Guide 7, and will continue to remain in the Exploration Stage until such time proven or probable reserves have been established, which may never occur. We prepare our consolidated financial statements in accordance with United States generally accepted accounting principles ("U.S. GAAP") under which acquisition costs of mineral rights are initially capitalized as incurred while pre-production expenditures are expensed as incurred until such time we exit the Exploration Stage. Expenditures relating to exploration activities are expensed as incurred and expenditures relating to pre-extraction activities are expensed as incurred until such time proven or probable reserves are established for that uranium project, after which subsequent expenditures relating to mine development activities for that particular project are capitalized as incurred.

We have neither established nor have any plans to establish proven or probable reserves for our uranium projects for which we plan on utilizing ISR mining, such as the Palangana Mine. Companies in the Production Stage as defined by the SEC under Industry Guide 7, having established proven and probable reserves and exited the Exploration Stage, typically capitalize expenditures relating to ongoing development activities, with corresponding depletion calculated over proven and probable reserves using the units-of-production method and allocated to future reporting periods to inventory and, as that inventory is sold, to cost of goods sold. As we are in the Exploration Stage, it has resulted in us reporting larger losses than if we had been in the Production Stage due to the expensing, instead of capitalizing, of expenditures relating to ongoing mill and mine pre-extraction activities. Additionally, there would be no corresponding amortization allocated to our future reporting periods since those costs would have been expensed previously, resulting in both lower inventory costs and cost of goods sold and results of operations with higher gross profits and lower losses than if we had been in the Production Stage. Any capitalized costs, such as acquisition costs of mineral rights, are depleted over the estimated extraction life using the straight-line method. As a result, our consolidated financial statements may not be directly comparable to the financial statements of companies in the Production Stage.

S-11

We are responsible for certain reclamation obligations in the future, primarily for the Hobson Facility and the Palangana Mine, and have recorded a liability on our balance sheet to recognize such estimated reclamation costs. There is a risk, however, that the actual reclamation costs when incurred in the future will exceed the estimated amounts recorded, which will adversely affect our results of operations and financial performance.

In general, where coverage is available and not prohibitively expensive relative to the perceived risk, we will maintain insurance against such risk, subject to exclusions and limitations. We currently maintain insurance against general commercial liability claims and certain physical assets used in our operations, subject to exclusions and limitations, however, we do not maintain insurance to cover all of the potential risks and hazards associated with our operations. We may be subject to liability for environmental, pollution or other hazards associated with our exploration, pre-extraction and extraction activities, which risks may not be insured against, which may exceed the limits of our insurance coverage or which we may elect not to insure against because of high premiums or other reasons. Furthermore, we cannot provide assurance that any insurance coverage we currently have will continue to be available at reasonable premiums or that such insurance will adequately cover any resulting liability.

From time to time, we examine opportunities to acquire additional mining assets and businesses. Any acquisition that we may choose to complete may be of a significant size, may change the scale of our business and operations, and may expose us to new geographic, political, operating, financial and geological risks. Our success in our acquisition activities depends on our ability to identify suitable acquisition candidates, negotiate acceptable terms for any such acquisition, and integrate the acquired operations successfully with those of our Company. Any acquisitions would be accompanied by risks which could have a material adverse effect on our business. For example, there may be a significant change in commodity prices after we have committed to complete the transaction and established the purchase price or exchange ratio; a material ore body may prove to be below expectations; we may have difficulty integrating and assimilating the operations and personnel of any acquired companies, realizing anticipated synergies and maximizing the financial and strategic position of the combined enterprise, and maintaining uniform standards, policies and controls across the organization; the integration of the acquired business or assets may disrupt our ongoing business and our relationships with employees, customers, suppliers and contractors; and the acquired business or assets may have unknown liabilities which may be significant. In the event that we choose to raise debt capital to finance any such acquisition, our leverage will be increased. If we choose to use equity as consideration for such acquisition, existing shareholders may suffer dilution. Alternatively, we may choose to finance any such acquisition with our existing resources. There can be no assurance that we would be successful in overcoming these risks or any other problems encountered in connection with such acquisitions.

Uranium exploration and pre-extraction programs and mining activities are subject to numerous stringent laws, regulations and standards at the federal, state, and local levels governing permitting, pre-extraction, extraction, exports, taxes, labor standards, occupational health, waste disposal, protection and reclamation of the environment, protection of endangered and protected species, mine safety, hazardous substances and other matters. Our compliance with these requirements requires significant financial and personnel resources.

The laws, regulations, policies or current administrative practices of any government body, organization or regulatory agency in the United States or any other applicable jurisdiction, may change or be applied or interpreted in a manner which may also have a material adverse effect on our operations. The actions, policies or regulations, or changes thereto, of any government body or regulatory agency or special interest group, may also have a material adverse effect on our operations.

S-12

Uranium exploration and pre-extraction programs and mining activities are subject to stringent environmental protection laws and regulations at the federal, state, and local levels. These laws and regulations, which include permitting and reclamation requirements, regulate emissions, water storage and discharges and disposal of hazardous wastes. Uranium mining activities are also subject to laws and regulations which seek to maintain health and safety standards by regulating the design and use of mining methods. Various permits from governmental and regulatory bodies are required for mining to commence or continue, and no assurance can be provided that required permits will be received in a timely manner.

Our compliance costs including the posting of surety bonds associated with environmental protection laws and regulations and health and safety standards have been significant to date, and are expected to increase in scale and scope as we expand our operations in the future. Furthermore, environmental protection laws and regulations may become more stringent in the future, and compliance with such changes may require capital outlays in excess of those anticipated or cause substantial delays, which would have a material adverse effect on our operations.

To the best of our knowledge, our operations are in compliance, in all material respects, with all applicable laws, regulations and standards. If we become subject to liability for any violations, we may not be able or may elect not to insure against such risk due to high insurance premiums or other reasons. Where coverage is available and not prohibitively expensive relative to the perceived risk, we will maintain insurance against such risk, subject to exclusions and limitations. However, we cannot provide any assurance that such insurance will continue to be available at reasonable premiums or that such insurance will be adequate to cover any resulting liability.

Our exploration and mining activities are dependent upon the grant of appropriate authorizations, licences, permits and consents, as well as continuation of these authorizations, licences, permits and consents already granted, which may be granted for a defined period of time, or may not be granted or may be withdrawn or made subject to limitations. There can be no assurance that all necessary authorizations, licences, permits and consents will be granted to us, or that authorizations, licences, permits and consents already granted will not be withdrawn or made subject to limitations.

The nuclear incident that occurred in Fukushima, Japan in March 2011 had significant and adverse effects on both the nuclear and uranium industries. If another nuclear incident were to occur, it may have further adverse effects for both industries. Public opinion of nuclear power as a source of electricity generation may be adversely affected, which may cause governments of certain countries to further increase regulation for the nuclear industry, reduce or abandon current reliance on nuclear power or reduce or abandon existing plans for nuclear power expansion. Any one of these occurrences has the potential to reduce current and/or future demand for nuclear power, resulting in lower demand for uranium and lower market prices for uranium, adversely affecting the Company's operations and prospects. Furthermore, the growth of the nuclear and uranium industries is dependent on continuing and growing public support of nuclear power as a source of electricity generation.

The marketability of uranium concentrates extracted by us will be affected by numerous factors beyond our control. These factors include macroeconomic factors, fluctuations in the market price of uranium, governmental regulations, land tenure and use, regulations concerning the importing and exporting of uranium and environmental protection regulations. The future effects of these factors cannot be accurately predicted, but any one or a combination of these factors may result in our inability to receive an adequate return on our invested capital.

S-13

The uranium industry is highly competitive, and our competition includes larger, more established companies with longer operating histories that not only explore for and produce uranium, but also market uranium and other products on a regional, national or worldwide basis. Due to their greater financial and technical resources, we may not be able to acquire additional uranium projects in a competitive bidding process involving such companies. Additionally, these larger companies have greater resources to continue with their operations during periods of depressed market conditions.

We hold certain mineral rights located in Paraguay through the acquisition of Piedra Rica Mining S.A. and Transandes Paraguay S.A., both companies incorporated in Paraguay. Operations in foreign jurisdictions outside of the U.S. and Canada, especially in developing countries, may be subject to additional risks as they may have different political, regulatory, taxation, economic and cultural environments that may adversely affect the value or continued viability of our rights. These additional risks include, but are not limited to: (i) changes in governments or senior government officials; (ii) changes to existing laws or policies on foreign investments, environmental protection, mining and ownership of mineral interests; (iii) renegotiation, cancellation, expropriation and nationalization of existing permits or contracts; (iv) foreign currency controls and fluctuations; and (v) civil disturbances, terrorism and war.

In the event of a dispute arising at our foreign operations in Paraguay, we may be subject to the exclusive jurisdiction of foreign courts or may not be successful in subjecting foreign persons to the jurisdiction of the courts in the United States or Canada. We may also be hindered or prevented from enforcing our rights with respect to a government entity or instrumentality because of the doctrine of sovereign immunity. Any adverse or arbitrary decision of a foreign court may have a material and adverse impact on our business, prospects, financial condition and results of operations.

Although we have taken reasonable measures to ensure proper title to our interests in mineral properties and other assets, there is no guarantee that the title to any of such interests will not be challenged. No assurance can be given that we will be able to secure the grant or the renewal of existing mineral rights and tenures on terms satisfactory to us, or that governments in the jurisdictions in which we operate will not revoke or significantly alter such rights or tenures or that such rights or tenures will not be challenged or impugned by third parties, including local governments, aboriginal peoples or other claimants. Our mineral properties may be subject to prior unregistered agreements, transfers or claims, and title may be affected by, among other things, undetected defects. A successful challenge to the precise area and location of our claims could result in us being unable to operate on our properties as permitted or being unable to enforce our rights with respect to our properties.

Due to the nature of our business, we may be subject to numerous regulatory investigations, civil claims, lawsuits and other proceedings in the ordinary course of our business including those described from time to time in our annual reports on Form 10-K and our quarterly reports on Form 10-Q under the heading, "Legal Proceedings." No reserves have been established for any potential liability relating to these lawsuits. The outcome of these lawsuits is uncertain and subject to inherent uncertainties, and the actual costs to be incurred will depend upon many unknown factors. We may be forced to expend significant resources in the defense of these suits, and we may not prevail. Defending against these and other lawsuits in the future may not only require us to incur significant legal fees and expenses, but may become time-consuming for us and detract from our ability to fully focus our internal resources on our business activities. The results of any legal proceeding cannot be predicted with certainty due to the uncertainty inherent in litigation, the difficulty of predicting decisions of regulators, judges and juries and the possibility that decisions may be reversed on appeal. There can be no assurances that these matters will not have a material adverse effect on our business, results of operations or financial position.

Our success is dependent on the efforts, abilities and continued service of certain senior officers and key employees and consultants. A number of our key employees and consultants have significant experience in the uranium industry. A loss of service from any one of these individuals may adversely affect our operations, and we may have difficulty or may not be able to locate and hire a suitable replacement.

The majority of our directors and officers are involved in other business ventures including similar capacities with other private or publicly-traded companies. Such individuals may have significant responsibilities to these other business ventures, including consulting relationships, which may require significant amounts of their available time. Conflicts of interest may include decisions on how much time to devote to our business affairs and what business opportunities should be presented to us. Our Code of Business Conduct for Directors, Officers and Employees provides for guidance on conflicts of interest.

The laws of the State of Nevada provide that our directors and officers will not be liable to the Company or its stockholders for monetary damages for all but certain types of conduct as directors and officers of the Company. Our Bylaws provide for broad indemnification powers to all persons against all damages incurred in connection with our business to the fullest extent provided or allowed by law. These indemnification provisions may require us to use our limited assets to defend our directors and officers against claims, and may have the effect of preventing stockholders from recovering damages against our directors and officers caused by their negligence, poor judgment or other circumstances.

Several of our directors and officers are nationals and/or residents of countries other than the U.S., and all or a substantial portion of such persons' assets are located outside of the U.S. As a result, it may be difficult for investors to effect service of process on such directors and officers, or enforce within the U.S. any judgments obtained against such directors and officers, including judgments predicated upon the civil liability provisions of the securities laws of the U.S. or any state thereof. Consequently, stockholders may be effectively prevented from pursuing remedies against such directors and officers under U.S. federal securities laws. In addition, stockholders may not be able to commence an action in a Canadian court predicated upon the civil liability provisions under U.S. federal securities laws. The foregoing risks also apply to those experts identified in this document that are not residents of the U.S.

Management's evaluation on the effectiveness of disclosure controls and procedures is designed to ensure that information required for disclosure in our public filings is recorded, processed, summarized and reported on a timely basis to our senior management, as appropriate, to allow timely decisions regarding required disclosure. Management's report on internal control over financial reporting is designed to provide reasonable assurance that transactions are properly authorized, assets are safeguarded against unauthorized or improper use and transactions are properly recorded and reported. Any system of controls, no matter how well designed and operated, is based in part upon certain assumptions designed to obtain reasonable, and not absolute, assurance as to its reliability and effectiveness.

On September 28, 2007, our common stock commenced trading on the NYSE MKT (formerly known as the American Stock Exchange and the NYSE Amex Equities Exchange) and prior to that, traded on the OTC Bulletin Board.

The global markets have experienced significant and increased volatility, especially over the recent past, which have been impacted by the effects of mass sub-prime mortgage defaults and liquidity problems of the asset-backed commercial paper market, resulting in a number of large financial institutions requiring government bailouts or filing for bankruptcy. The effects of these past events and any similar events in the future may continue to or further affect the global markets, which may directly affect the market price of our common stock and our accessibility for additional financing. Although this volatility may be unrelated to specific company performance, it can have an adverse effect on the market price of our shares which, historically, has fluctuated significantly and may continue to do so in the future.

In addition to the volatility associated with general economic trends and market conditions, the market price of our common stock could decline significantly due to the impact of any one or more events, including, but not limited to, the following: (i) volatility in the uranium market; (ii) occurrence of a major nuclear incident such as the events in Fukushima, Japan in March 2011; (iii) changes in the outlook for the nuclear power and uranium industries; (iv) failure to meet market expectations on our exploration, pre-extraction or extraction activities, including abandonment of key uranium projects; (v) sales of a large number of our shares held by certain stockholders including institutions and insiders; (vi) downward revisions to previous estimates on us by analysts; (vii) removal from market indices; (viii) legal claims brought forth against us; and (ix) introduction of technological innovations by competitors or in competing technologies.

Historically, we have relied on equity financing and more recently, on debt financing, as primary sources of financing. A prolonged decline in the market price of our common stock or a reduction in our accessibility to the global markets may result in our inability to secure additional financing which would have an adverse effect on our operations.

We are authorized to issue 750,000,000 shares of common stock of which 89,696,759 shares were issued and outstanding as of December 30, 2013. Future issuances for financings, mergers and acquisitions, exercise of stock options and share purchase warrants and for other reasons may result in significant dilution to and be issued at prices substantially below the price paid for our shares held by our existing stockholders. Significant dilution would reduce the proportionate ownership and voting power held by our existing stockholders, and may result in a decrease in the market price of our shares.

We also filed a Form S-3 "Shelf" Registration Statement that became effective September 2, 2011 which provides for the public offer and sale of certain securities of our Company from time to time, at our discretion, for gross proceeds of up to $50 million, of which approximately $34.4 million has been utilized (approximately $22.5 million pursuant to an offering of shares on April 10, 2012, approximately $7.1 million pursuant to an offering of units consisting of shares and warrants on October 23, 2013, and approximately $4.8 million representing the aggregate exercise price to purchase warrant shares upon exercise of the warrants issued as part of such units, although there is no guarantee that any of such warrants will be exercised), leaving appropriately $15.6 million available. We filed a further registration statement pursuant to Rule 462(b) on December 31, 2013 to register securities representing an additional 20% of such remaining amount, that is, an additional approximately $3.1 million. Such $15.6 million and further $3.1 million (for a total of approximately $18.7 million) will be utilized under the offering contemplated by this prospectus supplement and the accompanying prospectus.

S-16

Our common stock is currently listed on the NYSE MKT. In order to maintain this listing, we must maintain certain share prices, financial and share distribution targets, including maintaining a minimum amount of shareholders' equity and a minimum number of public shareholders. In addition to these objective standards, the NYSE MKT may delist the securities of any issuer if, in its opinion, the issuer's financial condition and/or operating results appear unsatisfactory; if it appears that the extent of public distribution or the aggregate market value of the security has become so reduced as to make continued listing on the NYSE MKT inadvisable; if the issuer sells or disposes of principal operating assets or ceases to be an operating company; if an issuer fails to comply with the NYSE MKT's listing requirements; if an issuer's common stock sells at what the NYSE MKT considers a "low selling price" and the issuer fails to correct this via a reverse split of shares after notification by the NYSE MKT; or if any other event occurs or any condition exists which makes continued listing on the NYSE MKT, in its opinion, inadvisable.

If the NYSE MKT delists our common stock, investors may face material adverse consequences, including, but not limited to, a lack of trading market for our securities, reduced liquidity, decreased analyst coverage of our securities, and an inability for us to obtain additional financing to fund our operations.

S-17

The amount of proceeds from this offering will depend upon the number of shares of our common stock sold and the market price at which they are sold. There can be no assurance that we will be able to sell any shares under or fully utilize the sales agreement with Cantor Fitzgerald & Co. as a source of financing. We intend to use the net proceeds, if any, from this offering to fund exploration and pre-extraction expenditures at our projects and for general corporate and working capital purposes.

Until such time as the net proceeds of the offering are used as described above, we intend to invest the net proceeds primarily in short-term bank guaranteed deposits or other substantially similar secure deposits.

S-18

In this offering, we are offering shares of our common stock.

The material terms and provisions of our common stock are described under the caption "Description of Common Shares" starting on page 13 of the accompanying prospectus.

S-19

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 related to the acquisition, ownership and disposition of common shares. Except as specifically set forth below, this summary does not discuss applicable tax reporting requirements. In addition, this summary does not take into account the individual facts and circumstances of any particular holder that may affect the U.S. federal income tax consequences to such holder. 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 particular holder. Each Non-U.S. Holder should consult its own tax advisors regarding the U.S. federal, state and local, and non-U.S. tax consequences related to the acquisition, ownership and disposition of common shares.

No legal opinion from U.S. legal counsel or ruling from the Internal Revenue Service (the "IRS") has been requested, or will be obtained, regarding the U.S. federal income tax consequences related to 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.

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 IRS, published administrative positions of the IRS, and U.S. court decisions that are applicable and, in each case, as in effect and available, as of the date of this prospectus supplement. Any of the authorities on which this summary is based could be changed in a material and adverse manner at any time, and any such change could be applied on a retroactive basis. This summary does not discuss the potential effects, whether adverse or beneficial, of any proposed legislation that, if enacted, could be applied on a retroactive basis.

As used in this summary, the term "Non-U.S. Holder" means a beneficial owner of common shares acquired pursuant to this prospectus supplement that, for U.S. federal income tax purposes, is not: (a) an individual who is a citizen or resident of the United States; (b) a corporation (or other entity taxable as a corporation for U.S. federal income tax purposes) created or organized in or under the laws of the United States, any state thereof or the District of Columbia; (c) an estate the income of which is subject to U.S. federal income taxation regardless of its source; (d) a trust that (1) is subject to the primary supervision of a court within the United States and the control of one or more U.S. persons for all substantial decisions of the trust or (2) has a valid election in effect under applicable Treasury Regulations to be treated as a U.S. person; or (e) a partnership or other entity or arrangement treated as a partnership for U.S. federal income tax purposes.

This summary deals only with persons or entities who hold common shares as a capital asset within the meaning of Section 1221 of the Code (generally, property held for investment purposes). This summary does not address all aspects of U.S. federal income taxation that may be applicable to holders in light of their particular circumstances or to holders subject to special treatment under U.S. federal income tax law, such as (without limitation):

S-20

• banks, insurance companies, and other financial institutions;
• dealers or traders in securities, commodities or foreign currencies;
• regulated investment companies;
• tax-exempt entities;
• U.S. expatriates or former long-term residents of the United States;
• persons holding common shares as part of a straddle, appreciated financial position, synthetic security, hedge, conversion or constructive sale transaction or other integrated investment;
• entities that acquire common shares that are treated as partnerships for U.S. federal income tax purposes and partners in such partnerships;
• real estate investment trusts;
• U.S. Holders that have a "functional currency" other than the U.S. dollar;
• holders that acquired common shares in connection with the exercise of employee stock options or otherwise as consideration for services; or
• holders that are "controlled foreign corporations" or "passive foreign investment companies."

Non-U.S. Holders that are subject to special provisions under the Code, including holders described immediately above, should consult their own tax advisors regarding the U.S. federal, state and local, and non-U.S. tax consequences arising from and relating to the acquisition, ownership and disposition of common shares.

If an entity or arrangement that is classified as a partnership (or other "pass-through" entity) for U.S. federal income tax purposes holds common shares, the U.S. federal income tax consequences to such entity and the partners (or other owners) of such entity generally will depend on the activities of the entity and the status of such partners (or owners). This summary does not address the tax consequences to any such owner or entity. Partners (or other owners) of entities or arrangements that are classified as partnerships or as "pass-through" entities for U.S. federal income tax purposes should consult their own tax advisors regarding the U.S. federal income tax consequences arising from and relating to the acquisition, ownership, and disposition of common shares.

This summary does not address the U.S. state and local, U.S. federal estate and gift, U.S. Medicare, U.S. federal alternative minimum tax, or non-U.S. tax consequences to Non-U.S. Holders of common shares. Each Non-U.S. Holder should consult its own tax advisors regarding the U.S. state and local, U.S. federal estate and gift, U.S. federal alternative minimum tax, and non-U.S. tax consequences of the acquisition, ownership, and disposition of common shares.

Distributions on common shares paid to Non-U.S. Holders will constitute dividends for U.S. federal income tax purposes to the extent paid from our current and accumulated earnings and profits, as determined under U.S. federal income tax principles. To the extent those distributions exceed current and accumulated earnings and profits, they will constitute a return of capital and will first reduce a Non-U.S. Holder's basis in common shares, but not below zero, and then will be treated as gain from the sale of stock, which will be taxable according to rules discussed below under the heading "Sale or Other Taxable Disposition of Common Shares." Any dividends paid to a Non-U.S. Holder with respect to common shares generally will be subject to withholding tax at a 30% gross rate, subject to any exemption or lower rate under an applicable treaty if the Non-U.S. Holder provides us with a properly executed IRS Form W-8BEN, unless the Non-U.S. Holder provides us with a properly executed IRS Form W-8ECI (or other applicable form) relating to income effectively connected with the conduct of a trade or business within the United States.

S-21

Dividends that are effectively connected with the conduct of a trade or business within the United States and includible in the Non-U.S. Holder's gross income are not subject to the withholding tax (assuming proper certification and disclosure), but instead are subject to U.S. federal income tax on a net income basis at applicable graduated individual or corporate rates. Any such effectively connected income received by a non-U.S. corporation may, under certain circumstances, be subject to an additional branch profits tax at a 30% rate, subject to any exemption or lower rate as may be specified by an applicable income tax treaty.

A Non-U.S. Holder of common shares who wishes to claim the benefit of an applicable treaty rate or exemption is required to satisfy certain certification and other requirements. If a Non-U.S. Holder is eligible for an exemption from or a reduced rate of U.S. withholding tax pursuant to an income tax treaty, it may obtain a refund of any excess amounts withheld by timely filing an appropriate claim for refund with the IRS.

In general, a Non-U.S. Holder of common shares will not be subject to U.S. federal income tax on gain recognized from a sale, exchange, or other taxable disposition of such common shares, unless:

• the gain is effectively connected with a U.S. trade or business carried on by the Non-U.S. Holder (and, where an income tax treaty applies, is attributable to a U.S. permanent establishment of the Non-U.S. Holder), in which case the Non-U.S. Holder will be subject to tax on the net gain from the disposition at regular graduated U.S. federal income tax rates, and if the Non-U.S. Holder is a corporation, may be subject to an additional U.S. branch profits tax at a gross rate equal to 30% of its effectively connected earnings and profits for that taxable year, subject to any exemption or lower rate as may be specified by an applicable income tax treaty;
• the Non-U.S. Holder is an individual who is present in the United States for 183 days or more in the taxable year of the disposition and certain other conditions are met, in which case the Non-U.S. Holder will be subject to a 30% tax on the gain from the sale, which may be offset by U.S. source capital losses; or
• we are or have been a "United States real property holding corporation" ("USRPHC") for U.S. federal income tax purposes at any time during the shorter of the Non-U.S. Holder's holding period or the 5-year period ending on the date of the disposition; provided that, as long as our common shares are regularly traded on an established securities market as determined under the Treasury Regulations (the "Regularly Traded Exception"), a Non-U.S. Holder would not be subject to taxation on the gain on the disposition of common shares under this rule unless the Non-U.S. Holder has owned more than 5% of our common stock at any time during such 5-year or shorter period (a "5% Shareholder"). Non-U.S. Holders should be aware that we have made no determination as to whether we are or have been a USRPHC, and we can provide no assurances that we are not and will not become a USRPHC in the future. In addition, in the event that we are or become a USRPHC, we can provide no assurances that the common shares will meet the Regularly Traded Exception at the time a Non-U.S. Holder purchases such common shares or sells, exchanges or otherwise disposes of such common shares. Non-U.S. Holders should consult with their own tax advisors regarding the consequences to them of investing in a USRPHC. As a USRPHC, a Non-U.S. Holder will be taxed as if any gain or loss were effectively connected with the conduct of a U.S. trade or business as described above in "Dividends" in the event that (i) such holder is a 5% Shareholder, or (ii) the Regularly Traded Exception is not satisfied during the relevant period.

Generally, we must report annually to the IRS and to Non-U.S. Holders the amount of dividends paid on the common shares to Non-U.S. Holders and the amount of tax, if any, withheld with respect to those dividends. Copies of the information returns reporting such dividends and withholding may also be made available to the tax authorities in the country in which a Non-U.S. Holder resides under the provisions of an applicable income tax treaty.

S-22

In general, a Non-U.S. Holder will not be subject to backup withholding with respect to payments of dividends by us, provided we receive a statement meeting certain requirements to the effect that the Non-U.S. Holder is not a U.S. person and we do not have actual knowledge or reason to know that the holder is a U.S. person, as defined under the Code, or the Non-U.S. Holder otherwise establishes an exemption. The requirements for the statement will be met if (1) the Non-U.S. Holder provides its name, address and U.S. taxpayer identification number, if any, and certifies, under penalty of perjury, that it is not a U.S. person (which certification may be made on IRS Form W-8BEN) or (2) a financial institution holding the instrument on behalf of the Non-U.S. Holder certifies, under penalty of perjury, that such statement has been received by it and furnishes us or the paying agent with a copy of the statement. In addition, a Non-U.S. Holder will be subject to information reporting and, depending on the circumstances, backup withholding with respect to payments of the proceeds of a sale of common shares within the United States or conducted through certain U.S.-related financial intermediaries, unless the statement described above has been received, and we do not have actual knowledge or reason to know that a holder is a U.S. person, as defined under the Code, or the Non-U.S. Holder otherwise establishes an exemption. Backup withholding is not an additional tax and any amounts withheld under the backup withholding rules will be allowed as a refund or a credit against a Non-U.S. Holder's U.S. federal income tax liability, if any, provided the required information is furnished in a timely manner to the IRS.

Under legislation enacted in 2010 and existing guidance issued thereunder, a 30% U.S. federal withholding tax may apply to dividends in respect of common shares, and gross proceeds from the sale of common shares, held by or through certain foreign financial institutions (including investment funds) beginning after June 30, 2014, in the case of dividends, and beginning after December 31, 2016, in the case of such gross proceeds, unless such institution enters into an agreement with the Secretary of the Treasury to report, on an annual basis, certain information regarding accounts with or interests in the institution held by certain U.S. persons and by certain non-U.S. entities that are wholly- or partially-owned by U.S. persons. Accordingly, the entity through which common shares are held will affect the determination of whether such withholding is required. Similarly, dividends in respect of common shares, and gross proceeds from the sale of common shares, held by certain investors that are non-financial non-U.S. entities will be subject to withholding at a rate of 30%, beginning after June 30, 2014, in the case of dividends, and beginning after December 31, 2016, in the case of such gross proceeds, unless such entity either (i) certifies that such entity does not have any "substantial U.S. owners" or (ii) provides certain information regarding the entity's "substantial U.S. owners," which will in turn be provided to the Secretary of the Treasury. Non-U.S. Holders should consult with their own tax advisors regarding the possible implications of the foregoing rules on their holding of common shares.

S-23

We have entered into a Controlled Equity Offering^SM sales agreement with Cantor Fitzgerald & Co., or Cantor, under which we may issue and sell shares of our common stock having an aggregate gross sales price of up to $18,695,000 from time to time through Cantor acting as agent. The sales agreement will be filed as an exhibit to a current report on Form 8-K filed under the Exchange Act and incorporated by reference in this prospectus supplement.

Upon delivery of a placement notice and subject to the terms and conditions of the sales agreement, Cantor may sell our common stock by any method permitted by law deemed to be an "at-the-market" offering as defined in Rule 415 promulgated under the Securities Act, including sales made directly on the NYSE MKT, on any other existing trading market for our common stock or to or through a market maker. Cantor may also sell our common stock by any other method permitted by law, including in privately negotiated transactions. We may instruct Cantor not to sell common stock if the sales cannot be effected at or above the price designated by us from time to time. We or Cantor may suspend the offering of common stock upon notice and subject to other conditions.

We will pay Cantor commissions, in cash, for its services in acting as agent in the sale of our common stock. Cantor will be entitled to a commission equal to an amount to be agreed upon based on the gross sales price per share sold. Because there is no minimum offering amount required as a condition to close this offering, the actual total public offering amount, commissions and proceeds to us, if any, are not determinable at this time. We have also agreed to reimburse Cantor for certain specified expenses, including the fees and disbursements of its legal counsel in an amount not to exceed $50,000. We estimate that the total expenses for the offering, excluding compensation and reimbursements payable to Cantor under the terms of the sales agreement, will be approximately $100,000.

Settlement for sales of common stock will occur on the third business day following the date on which any sales are made, or on some other date that is agreed upon by us and Cantor in connection with a particular transaction, in return for payment of the net proceeds to us. Sales of our common stock as contemplated in this prospectus will be settled through the facilities of The Depository Trust Company or by such other means as we and Cantor may agree upon. There is no arrangement for funds to be received in an escrow, trust or similar arrangement.

Cantor will use its commercially reasonable efforts, consistent with its sales and trading practices, to solicit offers to purchase the common stock shares under the terms and subject to the conditions set forth in the sales agreement. In connection with the sale of the common stock on our behalf, Cantor will be deemed to be an "underwriter" within the meaning of the Securities Act and the compensation of Cantor will be deemed to be underwriting commissions or discounts. We have agreed to provide indemnification and contribution to Cantor against certain civil liabilities, including liabilities under the Securities Act.

The offering of our common stock pursuant to the sales agreement will terminate upon the earlier of (i) the sale of all shares of our common stock subject to the sales agreement, or (ii) termination of the sales agreement as permitted therein. We and Cantor may each terminate the sales agreement at any time upon ten days' prior notice.

Cantor and its affiliates may in the future provide various investment banking, commercial banking and other financial services for us and our affiliates, for which services they may in the future receive customary fees. To the extent required by Regulation M, Cantor will not engage in any market making activities involving our common stock while the offering is ongoing under this prospectus supplement.

This prospectus supplement and the accompanying prospectus in electronic format may be made available on a website maintained by Cantor and Cantor may distribute this prospectus supplement and the accompanying prospectus electronically.

The Company was incorporated in the State of Nevada on May 16, 2003 under the name "Carlin Gold Inc." On January 24, 2005, we completed a reverse stock split of our shares of common stock on the basis of one share for each two outstanding shares and changed the Company's name to "Uranium Energy Corp." Effective February 28, 2006, we completed a forward split of our shares of common stock on the basis of 1.5 shares for each outstanding share to increase liquidity for our shares of common stock. Effective February 28, 2006, we amended our Articles of Incorporation with the Nevada Secretary of State increasing our authorized capital stock from 75,000,000 shares of common stock with a par value of $0.001 each to 750,000,000 shares of common stock with a par value of $0.001 each. In June 2007, we changed our fiscal year end from December 31 to July 31.

We are a U.S.-based company engaged in uranium production, development and exploration activities. Our wholly-owned Hobson Processing Facility forms the basis for our regional operating strategy in the South Texas Uranium Belt, which is a primary focus for the Company. By utilizing Hobson as a central processing site, it allows us to process uranium-loaded resins not only from the Palangana Mine but from other satellite mining operations within the South Texas Uranium Belt as they enter production.

However, no Prospectus Supplement or free writing prospectus will offer a security that is not registered and described in this Prospectus at the time of the effectiveness of the registration statement of which this Prospectus is a part.

We may sell the Securities on a continuous or delayed basis to or through underwriters, dealers or agents or directly to purchasers. The Prospectus Supplement, which we will provide to you each time we offer Securities, will set forth the names of any underwriters, dealers or agents involved in the sale of the Securities, and any applicable fee, commission or discount arrangements with them.

We may offer Common Shares. Holders of Common Shares are entitled to one vote per Common Share on all matters that require shareholder approval. Holders of our Common Shares are entitled to dividends when and if declared by our Board of Directors. Our Common Shares are described in greater detail in this Prospectus under "Description of Common Shares."

We may offer Debt Securities from time to time, in one or more series, as either senior or subordinated debt or as senior or subordinated convertible debt. The Debt Securities will be issued under one or more documents called indentures, which are contracts between our Company and a trustee for the holders of the Debt Securities. In this Prospectus, we have summarized certain general features of the Debt Securities under "Description of Debt Securities." We urge you, however, to read any Prospectus Supplement and any free writing prospectus that we may authorize to be provided to you related to the series of Debt Securities being offered, as well as the complete indentures that contain the terms of the Debt Securities. A form of indenture has been filed as an exhibit to the registration statement of which this Prospectus is a part, and supplemental indentures and forms of Debt Securities containing the terms of Debt Securities being offered will be filed as exhibits to the registration statement of which this Prospectus is a part, or incorporated by reference from a current report on Form 8-K that we file with the SEC.

We may offer Warrants for the purchase of Common Shares or Debt Securities, in one or more series, from time to time. We may issue Warrants independently or together with Common Shares, Debt Securities, or Subscription Receipts, and the Warrants may be attached to or separate from such securities.

The Warrants will be evidenced by warrant certificates and may be issued under one or more warrant indentures, which are contracts between our Company and a warrant trustee for the holders of the Warrants. We may also

-5-

choose to act as our own warrant trustee. In this Prospectus, we have summarized certain general features of the Warrants under "Description of Warrants." We urge you, however, to read any Prospectus Supplement and any free writing prospectus that we may authorize to be provided to you related to the series of Warrants being offered, as well as the warrant certificates and, if applicable, the warrant indentures, that contain the terms of the Warrants. Specific warrant certificates and, if applicable, warrant indentures, will contain additional important terms and provisions and will be filed as exhibits to the registration statement of which this Prospectus is a part, or incorporated by reference from a current report on Form 8-K that we file with the SEC.

We may issue Subscription Receipts, which will entitle holders to receive upon satisfaction of certain release conditions and for no additional consideration, Common Shares, Debt Securities, Warrants or any combination thereof. Subscription Receipts will be issued pursuant to one or more subscription receipt agreements, each to be entered into between our Company and an escrow agent, which will establish the terms and conditions of the Subscription Receipts. Each escrow agent will be a financial institution organized under the laws of the United States or any state thereof or Canada or a province thereof and authorized to carry on business as a trustee. A copy of the form of subscription receipt agreement will be filed as an exhibit to the registration statement of which this Prospectus is a part, or will be incorporated by reference from a current report on Form 8-K that we file with the SEC.

We may offer Units consisting of Common Shares, Debt Securities, Warrants and/or Subscription Receipts to purchase any of such securities in one or more series. In this Prospectus, we have summarized certain general features of the Units under "Description of Units." We urge you, however, to read any Prospectus Supplement and any free writing prospectus that we may authorize to be provided to you related to the series of Units being offered. We may evidence each series of units by unit certificates that we will issue under a separate unit agreement with a unit agent. We may also choose to act as our own unit agent. We will file as exhibits to the registration statement of which this Prospectus is a part, or will incorporate by reference from a current report on Form 8-K that we file with the SEC, any unit agreements that describe the terms of the series of Units we are offering before the issuance of the related series of Units.

We will need to raise additional financing to complete further exploration and development of our mineral properties. Furthermore, if the costs of our planned exploration and development programs are greater than anticipated, we may have to seek additional funds through public or private share offerings or arrangements with corporate partners. There can be no assurance that we will be successful in our efforts to raise the required funds, or on terms satisfactory to us. The continued exploration and development of our mineral properties and the development of our business will depend upon our ability to establish the commercial viability of our mineral properties and to ultimately develop cash flow from operations and reach profitable operations. We currently have no revenue from operations and are experiencing significant negative cash flow. Accordingly, the primary source of

-6-

funds presently available to us is through the sale of equity securities. In addition, we believe that debt financing may potentially be an alternative to us. Alternatively, we may finance our business by offering an interest in our mineral properties to be earned by another party or parties carrying out further exploration thereof or to obtain project or operating financing from financial institutions, neither of which is presently intended. Our future cash flows and the availability of financing will be subject to a number of variables, including the market price of uranium. We may not be able to obtain additional financing on favorable terms, if at all. If we are unable to obtain this additional financing, we will not be able to continue our exploration or development activities and our assessment of the commercial viability of our mineral properties.

Since inception, we have not established proven and probable reserves through the completion of feasibility studies for any of our mineral properties in accordance with SEC Industry Guide 7, and there are no plans to do so. Accordingly, we are classified as an exploration stage company. Although we announced initial production activities at our Palangana project on November 17, 2010, and continue to conduct development activities on our Palangana project as well as permitting activities on our Goliad project, there is no assurance that a commercially viable mineral deposit exists or will be established on any of our mineral properties in accordance with SEC Industry Guide 7. We will continue to conduct exploration activities on our other mineral property interests with the objective of ascertaining whether these properties contain economic quantities of uranium ore. The known mineralization at these projects has not been determined to be economic ore, and may never be determined to be economic. We will also continue to pursue the acquisition of new mineral property interests that we believe contain or have the potential to contain economic quantities of uranium ore. There is a substantial risk that these exploration activities will not result in discoveries of commercially recoverable quantities of ore.

Our long-term success depends on our ability to establish commercially recoverable quantities of ore on our mineral properties that can then be developed into commercially viable mining operations. Mineral exploration is highly speculative in nature, involves many risks and is frequently non-productive. These risks include unusual or unexpected geologic formations, and the inability to obtain suitable or adequate machinery, equipment or labor. The success of uranium exploration is determined in part by the following factors:

• identification of potential uranium mineralization based on superficial analysis;

• availability of government-granted exploration permits;

• the quality of management and geological and technical expertise; and

• the capital available for exploration.

Substantial expenditures are required to establish proven and probable reserves through drilling and analysis, to develop metallurgical processes to extract metal, and to develop the mining and processing facilities and infrastructure at any site chosen for mining. Whether a mineral deposit will be established or determined to be commercially viable depends on a number of factors, which include, without limitation, the particular attributes of the deposit, such as size, grade and proximity to infrastructure; metal prices, which fluctuate widely; and government regulations, including, without limitation, regulations relating to prices, taxes, royalties, land tenure, land use, importing and exporting of minerals and environmental protection. We may invest significant capital and resources in exploration activities and abandon such investments if we are unable to identify commercially exploitable mineral reserves. The decision to abandon a project may reduce the trading price of our common stock and impair our ability to raise future financing. We cannot provide any assurance to investors that we will discover mineralized material in sufficient quantities on our properties to justify commercial operations. Further, we will not be able to recover the funds that we spend on exploration if we are not able to establish commercially recoverable quantities of ore on our mineral properties.

We have a history of operating losses, expect to continue to incur losses, and may never be profitable. Further, we have been dependent on sales of our equity securities and debt financing to meet our cash requirements. We have incurred net losses totaling $90,176,718 from May 16, 2003 (inception) to April 30, 2011. We incurred net losses totaling $14,478,669 in the year ended July 31, 2010, $13,503,576 in the year ended July 31, 2009 and $19,236,124 in the year ended July 31, 2008. Further, we do not expect positive cash flow from operations in the near term. There is no assurance that actual cash requirements will not exceed our estimates. In particular, additional capital may be required in the event that: (i) the costs to acquire additional uranium exploration claims are more than we currently anticipate; (ii) exploration costs for additional claims increase beyond our expectations; (iii) development and mining expenditures exceed anticipated costs; or (iv) we encounter greater costs associated with general and administrative expenses or offering costs.

Our participation in an increasingly larger number of uranium minerals exploration prospects has required and will continue to require substantial capital expenditures. The uncertainty and factors described throughout this section may impede our ability to economically discover uranium prospects. As a result, we may not be able to achieve or sustain profitability or positive cash flows from operating activities in the future.

Since our inception on May 16, 2003, our activities have been limited to organizational efforts, obtaining working capital and acquiring, exploring and developing a very limited number of properties. As a result, there is limited historical financial and operating information available upon which to evaluate our future performance.

The business of minerals exploration and mining is subject to many risks and uncertainties, including those described in this section, and if uranium is found in economic quantities, the profitability of future uranium mining ventures depends upon factors beyond our control. The profitability of mining uranium properties if economic quantities of uranium are found is dependent upon many factors and risks beyond our control, including, but not limited to: (i) unanticipated ground and water conditions and adverse claims to water rights; (ii) geological problems; (iii) metallurgical and other processing problems; (iv) the occurrence of unusual weather or operating conditions and other force majeure events; (v) lower than expected ore grades; (vi) accidents; (vii) delays in the receipt of or failure to receive necessary government permits; (viii) delays in transportation; (ix) labor disputes; (x) government permit restrictions and regulation restrictions; (xi) unavailability of materials and equipment; and (xii) the failure of equipment or processes to operate in accordance with specifications or expectations.

The Company's exploration and mining activities are subject to the risks normally inherent in the industry, including, but not limited, to environmental hazards, flooding, fire, periodic or seasonal hazardous climate and weather conditions, unexpected rock formation, industrial accidents and metallurgical and other processing problems. These risks could result in damage to, or destruction of, mineral properties, production facilities or other properties; personal injury; environmental damage; delays in mining; increased production costs; monetary losses; and possible legal liability. The Company may become subject to liability which it cannot insure against or which it may elect not to insure due to high premium costs or other reasons. Where considered practical to do so the Company maintains insurance against risks in the operation of its business in amounts which the Company believes to be reasonable. Such insurance, however, contains exclusions and limitations on coverage. The Company cannot provide any assurance that such insurance will continue to be available, will be available at economically acceptable premiums or will be adequate to cover any resulting liability. In some cases, coverage is not available or considered too expensive relative to the perceived risk.

The uranium exploration and mining industry is intensely competitive, and we compete with other companies that have greater resources. Many of these companies not only explore for and produce uranium, but also market uranium and other products on a regional, national or worldwide basis. These companies may be able to pay more

-8-

for productive uranium properties and exploratory prospects or define, evaluate, bid for and purchase a greater number of properties and prospects than our financial or human resources permit. In addition, these companies may have a greater ability to continue exploration and mining activities during periods of low uranium market prices. Our larger competitors may be able to absorb the burden of present and future federal, state, local and other laws and regulations more easily than we can, which would adversely affect our competitive position. Our ability to acquire additional properties and to explore them in the future will be dependent upon our ability to evaluate and select suitable properties and to consummate transactions in a highly competitive environment. In addition, because we have fewer financial and human resources than many companies in our industry, we may be at a disadvantage in bidding for exploratory prospects.

If we are successful in acquiring additional properties, some or all of the properties may not produce positive results of exploration, or we may not complete exploration of such prospects within specified time periods which may cause the forfeiture of the lease in that prospect. There can be no assurance that we will be able to successfully integrate acquired properties, which could result in substantial costs and delays or other operational, technical or financial problems. Further, acquisitions could disrupt ongoing business operations. If any of these events occur, it would have a material adverse effect upon our operations and results from operations.

The marketability of natural resources which may be acquired or discovered by us will be affected by numerous factors beyond our control. These factors include macroeconomic factors, market fluctuations in commodity pricing and demand, the proximity and capacity of natural resource markets and processing equipment, governmental regulations, land tenure, land use, regulation concerning the importing and exporting of uranium and environmental protection regulations. The exact effect of these factors cannot be accurately predicted, but the combination of these factors may result in us not receiving an adequate return on invested capital to be profitable or viable.

If economic quantities of uranium are found on any lease owned by us in sufficient quantities to warrant uranium mining operations, such mining operations are subject to federal, state, and local laws relating to the protection of the environment, including laws regulating removal of natural resources from the ground and the discharge of materials into the environment. Uranium mining operations are also subject to federal, state, and local laws and regulations which seek to maintain health and safety standards by regulating the design and use of mining methods and equipment. Various permits from government bodies are required for mining operations to be conducted; other than what has been previously disclosed herein, no assurance can be given that such permits will be received. Environmental standards imposed by federal, provincial, or local authorities may be changed and any such changes may have material adverse effects on our activities. Moreover, compliance with such laws may cause substantial delays or require capital outlays in excess of those anticipated, thus resulting in an adverse effect on us. Additionally, we may be subject to liability for pollution or other environmental damages which we may elect not to insure against due to prohibitive premium costs and other reasons. To date, we have not been required to spend material amounts on compliance with environmental regulations. However, we may be required to do so in the future and this may affect our ability to expand or maintain our operations.

Uranium minerals exploration, development and mining operations are subject to stringent federal, state, provincial, and local laws and regulations relating to improving or maintaining environmental quality. Environmental laws often require parties to pay for remedial action or to pay damages regardless of fault. Environmental laws also often impose liability with respect to divested or terminated operations, even if the operations were terminated or divested of many years ago.

Our uranium mining operations and exploration activities are or will be subject to extensive laws and regulations governing prospecting, development, production, exports, taxes, labor standards, occupational health, waste disposal, protection and remediation of the environment, protection of endangered and protected species, mine safety, toxic substances and other matters. Uranium mining is also subject to risks and liabilities associated with

-9-

pollution of the environment and disposal of waste products occurring as a result of mineral exploration and production. Compliance with these laws and regulations will impose substantial costs on us and will subject us to significant potential liabilities.

Costs associated with environmental liabilities and compliance are expected to increase with the increasing scale and scope of operations and we expect these costs may increase in the future.

We believe that our operations comply, in all material respects, with all applicable environmental regulations. However, we are not fully insured at the current date against possible environmental risks.

The laws, regulations, policies or current administrative practices of any government body, organization or regulatory agency in the United States or any other applicable jurisdiction, may be changed, applied or interpreted in a manner which will fundamentally alter our ability to carry on business. The actions, policies or regulations, or changes thereto, of any government body or regulatory agency, or other special interest groups, may have a detrimental effect on us. Any or all of these situations may have a negative impact on our ability to operate and/or our profitably.

Other than what has been previously disclosed herein, there are no assurances if and when a particular mineral property of the Company can enter into production. The amounts of future production for all our projects, including Palangana, are based on the estimates prepared by or for the Company. The capital and operating costs to take the Company's projects into production may be significantly higher than anticipated. Capital and operating costs of production and economic returns are based on estimates prepared by or for the Company may differ significantly from their actual values. There can be no assurance that the Company's actual capital and operating costs will not be higher than currently anticipated.

In addition, the construction and development of mines and infrastructure are complex. Resources invested in construction and development may yield outcomes that may differ significantly from those anticipated by the Company.

Our extremely limited personnel means that we would be required to spend significant sums of money to locate and train new employees in the event any of our employees resign or terminate their employment with us for any reason. Due to our limited operating history and financial resources, we are entirely dependent on the continued service of Amir Adnani, our President, Chief Executive Officer, Principal Executive Officer and a director, and Harry Anthony, our Chief Operating Officer and a director. We may not have the financial resources to hire a replacement if any of our officers were to die. The loss of service of any of these employees could therefore significantly and adversely affect our operations.

Some of our officers and directors serve only part time and may be subject to conflicts of interest. Each may devote part of his working time to other business endeavors, including consulting relationships with other corporate entities, and may have responsibilities to these other entities. Such conflicts may include deciding how much time to devote to our affairs, as well as what business opportunities should be presented to us. Because of these relationships, some of our officers and directors may be subject to conflicts of interest.

Nevada law provides that our officers and directors will not be liable to the Company or its stockholders for monetary damages for all but certain types of conduct as officers and directors. Our Bylaws permit us broad indemnification powers to all persons against all damages incurred in connection with our business to the fullest extent provided or allowed by law. The exculpation provisions may have the effect of preventing stockholders from

-10-

recovering damages against our officers and directors caused by their negligence, poor judgment or other circumstances. The indemnification provisions may require us to use our limited assets to defend our officers and directors against claims, including claims arising out of their negligence, poor judgment, or other circumstances.

Sales of a substantial number of shares of our common stock in the public market by certain stockholders could cause a reduction in the market price of our common stock. As of August 17, 2011, we had 73,487,337 shares of common stock issued and outstanding, stock options outstanding to purchase 8,579,750 shares and share purchase warrants outstanding to purchase 4,348,983 shares.

The sale of a substantial number of shares into the public market of previously restricted shares, or upon exercise of stock options or warrants, could place downward pressure on the price of our common stock.

Our common stock commenced trading on the NYSE Amex Equities exchange (formerly known as the American Stock Exchange) on September 28, 2007, and previously traded on the OTC Bulletin Board, and the trading price has fluctuated. In addition to volatility associated with securities in general, the value of your investment could decline due to the impact of any of the following factors upon the market price of our common stock: (i) disappointing results from our discovery or development efforts; (ii) failure to meet our revenue or profit goals or operating budget; (iii) decline in demand for our common stock; (iv) downward revisions in securities analysts' estimates or changes in general market conditions; (v) technological innovations by competitors or in competing technologies; (vi) lack of funding generated for operations; (vii) investor perception of our industry or our prospects; and (viii) general economic trends.

In addition, stock markets have experienced price and volume fluctuations and the market prices of securities have been highly volatile. These fluctuations are often unrelated to operating performance and may adversely affect the market price of our common stock. As a result, investors may be unable to sell their shares at a fair price and you may lose all or part of your investment.

The Board of Directors has the authority to issue additional shares of our capital stock to provide additional financing in the future and the issuance of any such shares may result in a reduction of the book value or market price of the outstanding shares of our common stock. If we do issue any such additional shares, such issuance also will cause a reduction in the proportionate ownership and voting power of all other stockholders. As a result of such dilution, if you acquire shares of our common stock, your proportionate ownership interest and voting power could be decreased. Further, any such issuances could result in a change of control.

Because the market price of the common stock has fluctuated and may trade at times at less than $5 per share, the common stock may be classified from time to time as a "penny stock." SEC Rule 15g-9 under the Exchange Act imposes additional sales practice requirements on broker-dealers that recommend the purchase or sale of penny stocks to persons other than those who qualify as an "established customer" or an "accredited investor." This includes the requirement that a broker-dealer must make a determination that investments in penny stocks are suitable for the customer and must make special disclosures to the customers concerning the risk of penny stocks. Many broker-dealers decline to participate in penny stock transactions because of the extra requirements imposed on penny stock transactions. Application of the penny stock rules to our common stock from time to time may limit the

-11-

market liquidity of our shares, which in turn affects the ability of holders of our common stock to resell the shares they purchase, and they may not be able to resell at prices at or above the prices they paid.

A decline in the price of our common stock could result in a reduction in the liquidity of our common stock and a reduction in our ability to raise additional capital for our operations. Because our operations to date have been principally financed through the sale of equity securities, a decline in the price of our common stock could have an adverse effect upon our liquidity and our continued operations. A reduction in our ability to raise equity capital in the future would have a material adverse effect upon our business plan and operations, including our ability to continue our current operations. If our stock price declines, we may not be able to raise additional capital or generate funds from operations sufficient to meet our obligations.

A majority of our directors and officers are nationals and/or residents of countries other than the United States, and all or a substantial portion of such persons' assets are located outside the United States. As a result, it may be difficult for investors to effect service of process on our directors or officers, or enforce within the United States or Canada any judgments obtained against us or our officers or directors, including judgments predicated upon the civil liability provisions of the securities laws of the United States or any state thereof. Consequently, you may be effectively prevented from pursuing remedies under U.S. federal securities laws against them. In addition, investors may not be able to commence an action in a Canadian court predicated upon the civil liability provisions of the securities laws of the United States. The foregoing risks also apply to those experts identified in this prospectus that are not residents of the United States.

This Prospectus and the documents incorporated herein by reference contain "forward-looking-statements" within the meaning of the Private Securities Litigation Reform Act of 1995. Such forward-looking statements concern our anticipated results and developments in our operations in future periods, planned exploration and, if warranted, development of our properties, plans related to our business and other matters that may occur in the future.

This list is not exhaustive of the factors that may affect our forward-looking statements. Some of the important risks and uncertainties that could affect forward-looking statements are described further under the sections titled "Risk Factors" of this Prospectus. Should one or more of these risks or uncertainties materialize, or should underlying assumptions prove incorrect, actual results may vary materially from those anticipated, believed, estimated or expected. We caution readers not to place undue reliance on any such forward-looking statements, which speak only as of the date made. We disclaim any obligation subsequently to revise any forward-looking statements to reflect events or circumstances after the date of such statements or to reflect the occurrence of anticipated or unanticipated events.

We did not have any fixed charges during the five fiscal years ended July 31, 2010 or for our period ended April 30, 2011. Accordingly, we have no ratio of earnings to fixed charges to illustrate for such periods.

Except as otherwise provided in the applicable Prospectus Supplement, we intend to use the net proceeds from the sale of the Securities covered by this Prospectus for general corporate purposes, which may include working capital, capital expenditures, acquisitions, exploration and development of existing or acquired mineral properties or repayment of indebtedness.

We are authorized to issue 750,000,000 common shares with a par value of $0.001. Upon liquidation, dissolution or winding up of our Company, the holders of our common shares are entitled to share ratably in all net assets available for distribution to common stockholders after payment to creditors. Our common stock is not convertible or redeemable and has no preemptive, subscription or conversion rights. Each outstanding share of common stock is entitled to one vote on all matters submitted to a vote of stockholders. There are no cumulative voting rights.

The holders of outstanding shares of common stock are entitled to receive dividends out of assets legally available therefore at such times and in such amounts as our board of directors may from time to time determine. Holders of common stock will share equally on a per share basis in any dividend declared by the board of directors. We have not paid any dividends on our common stock and do not anticipate paying any cash dividends on such stock in the foreseeable future.

-13-

We may, from time to time, issue Common Shares or other securities otherwise than through the Offering of Securities pursuant to this Prospectus.

We may issue Debt Securities in one or more series under an indenture (the "Indenture"), to be entered into between us and Transfer Online, Inc. as trustee. The Indenture will be subject to and governed by the United States Trust Indenture Act of 1939, as amended (the "Trust Indenture Act"). A copy of the form of the Indenture will be filed with the SEC as an exhibit to the registration statement of which this Prospectus forms a part and will be filed on SEDAR. The following description sets forth certain general terms and provisions of the Debt Securities and is not intended to be complete. For a more complete description, prospective investors should refer to the Indenture and the terms of the Debt Securities. If Debt Securities are issued, we will describe in the applicable Prospectus Supplement the particular terms and provisions of any series of Debt Securities and a description of how the general terms and provisions described below may apply to that series of Debt Securities. Prospective investors should rely on information in the applicable Prospectus Supplement and not on the following information to the extent that the information in such Prospectus Supplement is different from the following information. We will file as exhibits to the registration statement of which this Prospectus is a part, or will incorporate by reference from a current report on Form 8-K that we file with the SEC, any supplemental indenture describing the terms and conditions of Debt Securities we are offering before the issuance of such Debt Securities.

We may issue debt securities and incur additional indebtedness other than through the offering of Debt Securities pursuant to this Prospectus.

The Indenture will not limit the aggregate principal amount of Debt Securities that we may issue under the Indenture and will not limit the amount of other indebtedness that we may incur. The Indenture will provide that we may issue Debt Securities from time to time in one or more series and may be denominated and payable in U.S. dollars, Canadian dollars or any foreign currency. Unless otherwise indicated in the applicable Prospectus Supplement, the Debt Securities will be unsecured obligations of our Company. The Indenture will also permit our Company to increase the principal amount of any series of the Debt Securities previously issued and to issue that increased principal amount.

The applicable Prospectus Supplement for any series of Debt Securities that we offer will describe the specific terms of the Debt Securities and may include, but is not limited to, any of the following:

• the title of the Debt Securities;

• the aggregate principal amount of the Debt Securities;

• the percentage of principal amount at which the Debt Securities will be issued;

• whether payment on the Debt Securities will be senior or subordinated to our other liabilities or obligations;

• whether payment of the Debt Securities will be guaranteed by any other person;

• the date or dates, or the methods by which such dates will be determined or extended, on which we may issue the Debt Securities and the date or dates, or the methods by which such dates will be determined or extended, on which we will pay the principal and any premium on the Debt Securities and the portion (if less than the principal amount) of Debt Securities to be payable upon a declaration of acceleration of maturity;

• whether the Debt Securities will bear interest, the interest rate (whether fixed or variable) or the method of determining the interest rate, the date from which interest will accrue, the dates on which we will pay interest and the record dates for interest payments, or the methods by which such dates will be determined or extended;

-14-

• the place or places we will pay principal, premium, if any, and interest and the place or places where Debt Securities can be presented for registration of transfer or exchange;

• whether and under what circumstances we will be required to pay any additional amounts for withholding or deduction for taxes with respect to the Debt Securities, and whether and on what terms we will have the option to redeem the Debt Securities rather than pay the additional amounts;

• whether we will be obligated to redeem or repurchase the Debt Securities pursuant to any sinking or purchase fund or other provisions, or at the option of a holder and the terms and conditions of such redemption;

• whether we may redeem the Debt Securities prior to maturity and the terms and conditions of any such redemption;

• the denominations in which we will issue any registered Debt Securities, if other than denominations of $1,000 and any multiple of $l,000 and, if other than denominations of $5,000, the denominations in which any unregistered debt security shall be issuable;

• whether we will make payments on the Debt Securities in a currency or currency unit other than U.S. dollars or by delivery of our common shares or other property;

• whether payments on the Debt Securities will be payable with reference to any index, formula or other method;

• whether we will issue the Debt Securities as global securities and, if so, the identity of the depositary for the global securities;

• whether we will issue the Debt Securities as unregistered securities, registered securities or both;

• any changes or additions to events of default or covenants whether or not such events of default or covenants are consistent with the events of default or covenants in the Indenture;

• any other terms, conditions, rights and preferences (or limitations on such rights and preferences) including covenants and events of default which apply solely to a particular series of the Debt Securities being offered which do not apply generally to other Debt Securities, or any covenants or events of default generally applicable to the Debt Securities which do not apply to a particular series of the Debt Securities.

Unless stated otherwise in the applicable Prospectus Supplement, no holder of Debt Securities will have the right to require our Company to repurchase the Debt Securities and there will be no increase in the interest rate if we become involved in a highly leveraged transaction or if our Company has a change of control.

We may issue Debt Securities bearing no interest or interest at a rate below the prevailing market rate at the time of issuance, and offer and sell the Debt Securities at a discount below their stated principal amount. We may also sell any of the Debt Securities for a foreign currency or currency unit, and payments on the Debt Securities may be payable in a foreign currency or currency unit. In any of these cases, we will describe certain Canadian federal and U.S. federal income tax consequences and other special considerations in the applicable Prospectus Supplement.

We may issue Debt Securities with terms different from those of Debt Securities previously issued and, without the consent of the holders thereof, we may reopen a previous issue of a series of Debt Securities and issue additional Debt Securities of such series (unless the reopening was restricted when such series was created).

-15-

Unless otherwise indicated in an applicable Prospectus Supplement, the Debt Securities will be unsecured obligations and will rank equally with all of our other unsecured and other subordinated debt from time to time outstanding and equally with other Debt Securities issued under the Indenture. The Indenture will provide that the Debt Securities will be subordinated to and junior in right of payment to all present and future Senior Indebtedness. "Senior Indebtedness" will be defined in the Indenture as: (a) all indebtedness of our Company in respect of borrowed money, other than: (i) indebtedness evidenced by the Debt Securities; and (ii) indebtedness which, by the terms of the instrument creating or evidencing it, is expressed to rank in right of payment equally with or subordinate to the indebtedness evidenced by the Debt Securities; (b) all obligations of our Company for the reimbursement of amounts paid pursuant to any letter of credit, banker's acceptance or similar credit transaction; and (c) all obligations of the type referred to in paragraphs (a) through (b) above of other persons for the payment of which we are responsible or liable as obligor, guarantor or otherwise. For greater certainty, "Senior Indebtedness" will include all indebtedness of our Company for borrowed money which is outstanding as at the date of the Indenture.

Our Board of Directors may establish the extent and manner, if any, to which payment on or in respect of a series of Debt Securities will be senior or will be subordinated to the prior payment of our other liabilities and obligations, other than Senior Indebtedness, and whether the payment of principal, premium, if any, and interest, if any, will be guaranteed by any other person and the nature and priority of any security.

Unless otherwise specified in the applicable Prospectus Supplement, a series of the Debt Securities may be issued in whole or in part in global form as a "global security" and will be registered in the name of or issued in bearer form and be deposited with a depositary, or its nominee, each of which will be identified in the applicable Prospectus Supplement relating to that series. Unless and until exchanged, in whole or in part, for the Debt Securities in definitive registered form, a global security may not be transferred except as a whole by the depositary for such global security to a nominee of the depositary, by a nominee of the depositary to the depositary or another nominee of the depositary or by the depositary or any such nominee to a successor of the depositary or a nominee of the successor.

The specific terms of the depositary arrangement with respect to any portion of a particular series of the Debt Securities to be represented by a global security will be described in the applicable Prospectus Supplement relating to such series. We anticipate that the provisions described in this section will apply to all depositary arrangements.

Upon the issuance of a global security, the depositary therefor or its nominee will credit, on its book entry and registration system, the respective principal amounts of the Debt Securities represented by the global security to the accounts of such persons, designated as "participants", having accounts with such depositary or its nominee. Such accounts shall be designated by the underwriters, dealers or agents participating in the distribution of the Debt Securities or by our Company if such Debt Securities are offered and sold directly by our Company. Ownership of beneficial interests in a global security will be limited to participants or persons that may hold beneficial interests through participants. Ownership of beneficial interests in a global security will be shown on, and the transfer of that ownership will be effected only through, records maintained by the depositary therefor or its nominee (with respect to interests of participants) or by participants or persons that hold through participants (with respect to interests of persons other than participants). The laws of some states in the United States may require that certain purchasers of securities take physical delivery of such securities in definitive form.

So long as the depositary for a global security or its nominee is the registered owner of the global security or holder of a global security in bearer form, such depositary or such nominee, as the case may be, will be considered the sole owner or holder of the Debt Securities represented by the global security for all purposes under the Indenture. Except as provided below, owners of beneficial interests in a global security will not be entitled to have a series of the Debt Securities represented by the global security registered in their names, will not receive or be entitled to receive physical delivery of such series of the Debt Securities in definitive form and will not be considered the owners or holders thereof under the Indenture.

-16-

Any payments of principal, premium, if any, and interest, if any, on global securities registered in the name of a depositary or securities registrar will be made to the depositary or its nominee, as the case may be, as the registered owner of the global security representing such Debt Securities. None of our Company, any trustee or any paying agent for the Debt Securities represented by the global securities will have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests of the global security or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests.

We expect that the depositary for a global security or its nominee, upon receipt of any payment of principal, premium, if any, or interest, if any, will credit participants' accounts with payments in amounts proportionate to their respective beneficial interests in the principal amount of the global security as shown on the records of such depositary or its nominee. We also expect that payments by participants to owners of beneficial interests in a global security held through such participants will be governed by standing instructions and customary practices, as is now the case with securities held for the accounts of customers registered in "street name", and will be the responsibility of such participants.

If a depositary for a global security representing a particular series of the Debt Securities is at any time unwilling or unable to continue as depositary or, if at any time the depositary for such series shall no longer be registered or in good standing under the Exchange Act, and a successor depositary is not appointed by us within 90 days, we will issue such series of the Debt Securities in definitive form in exchange for a global security representing such series of the Debt Securities. If an event of default under the Indenture has occurred and is continuing, Debt Securities in definitive form will be printed and delivered upon written request by the holder to the trustee. In addition, we may at any time and in our sole discretion determine not to have a series of the Debt Securities represented by a global security and, in such event, will issue a series of the Debt Securities in definitive form in exchange for all of the global securities representing that series of Debt Securities.

A series of the Debt Securities may be issued in definitive form, solely as registered securities, solely as unregistered securities or as both registered securities and unregistered securities. Registered securities will be issuable in denominations of $1,000 and integral multiples of $1,000 and unregistered securities will be issuable in denominations of $5,000 and integral multiples of $5,000 or, in each case, in such other denominations as may be set out in the terms of the Debt Securities of any particular series. Unless otherwise indicated in the applicable Prospectus Supplement, unregistered securities will have interest coupons attached.

Unless otherwise indicated in the applicable Prospectus Supplement, payment of principal, premium, if any, and interest, if any, on the Debt Securities (other than global securities) will be made at the office or agency designated by our Company, or at our option we can pay principal, interest, if any, and premium, if any, by cheque mailed or delivered to the address of the person entitled at the address appearing in the security register of the trustee or electronic funds wire or other transmission to an account of persons who meet certain thresholds set out in the Indenture who are entitled to receive payments by wire transfer. Unless otherwise indicated in the applicable Prospectus Supplement, payment of interest, if any, will be made to the persons in whose name the Debt Securities are registered at the close of business on the day or days specified by us.

At the option of the holder of Debt Securities, registered securities of any series will be exchangeable for other registered securities of the same series, of any authorized denomination and of a like aggregate principal amount. If, but only if, provided in an applicable Prospectus Supplement, unregistered securities (with all unmatured coupons, except as provided below, and all matured coupons in default) of any series may be exchanged for registered securities of the same series, of any authorized denominations and of a like aggregate principal amount and tenor. In such event, unregistered securities surrendered in a permitted exchange for registered securities between a regular record date or a special record date and the relevant date for payment of interest shall be surrendered without the coupon relating to such date for payment of interest, and interest will not be payable on such date for payment of interest in respect of the registered security issued in exchange for such unregistered security, but will be payable only to the holder of such coupon when due in accordance with the terms of the Indenture. Unless otherwise specified in an applicable Prospectus Supplement, unregistered securities will not be issued in exchange for registered securities.

-17-

The applicable Prospectus Supplement may indicate the places to register a transfer of the Debt Securities in definitive form. Service charges may be payable by the holder for any registration of transfer or exchange of the Debt Securities in definitive form, and we may, in certain instances, require a sum sufficient to cover any tax or other governmental charges payable in connection with these transactions.

We shall not be required to:

• issue, register the transfer of or exchange any series of the Debt Securities in definitive form during a period beginning at the opening of 15 business days before any selection of securities of that series of the Debt Securities to be redeemed and ending on the relevant date of notice of such redemption, as provided in the Indenture;

• register the transfer of or exchange any registered security in definitive form, or portion thereof, called for redemption, except the unredeemed portion of any registered security being redeemed in part;

• exchange any unregistered security called for redemption except to the extent that such unregistered security may be exchanged for a registered security of that series and like tenor; provided that such registered security will be simultaneously surrendered for redemption with written instructions for payment consistent with the provisions of the Indenture; or

• issue, register the transfer of or exchange any of the Debt Securities in definitive form which have been surrendered for repayment at the option of the holder, except the portion, if any, of such Debt Securities not to be so repaid.

The Indenture will provide that we may not amalgamate or consolidate with, merge into or enter into any statutory arrangement with any other person or, directly or indirectly, convey, transfer or lease all or substantially all of our properties and assets to another person, unless among other items:

• the resulting, surviving or transferee person is organized and existing under the laws of Canada, or any province or territory thereof, the United States, any state thereof or the District of Columbia, or, if the amalgamation, merger, consolidation, statutory arrangement or other transaction would not impair the rights of holders, any other country;

• the resulting, surviving or transferee person, if other than our Company, assumes all of our obligations under the Debt Securities and the Indenture; and

• immediately after the transaction, no default or event of default under the Indenture shall have happened and be continuing.

When such a successor person assumes our obligations in such circumstances, subject to certain exceptions, we shall be discharged from all obligations and covenants under the Debt Securities and the Indenture.

We will file with the trustee, within 20 days after we file or furnish them with the SEC, copies of our annual reports and of the information, documents and other reports (or copies of such portions of any of the foregoing as the SEC may by rules and regulations prescribe) which we are required to file or furnish with the SEC pursuant to Section 13 or 15(d) of the Exchange Act.

Notwithstanding that we may not remain subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act or otherwise report on an annual and quarterly basis on forms provided for such annual and quarterly reporting pursuant to rules and regulations promulgated by the SEC, we will continue to provide the trustee:

• within 20 days after the time periods required for the filing or furnishing of such forms by the SEC, annual reports on Form 10-K or any successor form, quarterly reports on Form 10-Q or any successor form and current reports of Form 8-K or any successor form.

-18-

Unless otherwise specified in the applicable Prospectus Supplement relating to a particular series of Debt Securities, the following is a summary of events which will, with respect to any series of the Debt Securities, constitute an event of default under the Indenture with respect to the Debt Securities of that series:

• we fail to pay principal of, or any premium on, or any Additional Amounts in respect of, any Debt Security of that series when it is due and payable;

• we fail to pay interest (including Additional Amounts) payable on any Debt Security of that series when it becomes due and payable, and such default continues for 30 days;

• we fail to make any required sinking fund or analogous payment for that series of Debt Securities;

• we fail to observe or perform any of our covenants or agreements in the Indenture that affect or are applicable to the Debt Securities of that series for 90 days after written notice to us by the trustee or to us and the trustee by holders of at least 25% in aggregate principal amount of the outstanding Debt Securities of that series;

• a default (as defined in any indenture or instrument under which we or one of our subsidiaries has at the date of the Indenture or will thereafter have outstanding any indebtedness) has occurred and is continuing, or we or any of our subsidiaries has failed to pay principal amounts with respect to such indebtedness at maturity and such event of default or failure to pay has resulted in such indebtedness under such indenture or instrument being declared due, payable or otherwise being accelerated, in either event so that an amount in excess of the greater of $15,000,000 and 2% of our shareholders' equity will be or become due, payable and accelerated upon such declaration or prior to the date on which the same would otherwise have become due, payable and accelerated (the "Accelerated Indebtedness"), and such acceleration will not be rescinded or annulled, or such event of default or failure to pay under such indenture or instrument will not be remedied or cured, whether by payment or otherwise, or waived by the holders of such Accelerated Indebtedness, then (i) if the Accelerated Indebtedness will be as a result of an event of default which is not related to the failure to pay principal or interest on the terms, at the times, and on the conditions set out in any such indenture or instrument, it will not be considered an event of default for the purposes of the indenture governing the Debt Securities until 30 days after such indebtedness has been accelerated, or (ii) if the Accelerated Indebtedness will occur as a result of such failure to pay principal or interest or as a result of an event of default which is related to the failure to pay principal or interest on the terms, at the times, and on the conditions set out in any such indenture or instrument, then (A) if such Accelerated Indebtedness is, by its terms, non-recourse to our Company or our subsidiaries, it will be considered an event of default for purposes of the Indenture governing the Debt Securities; or (B) if such Accelerated Indebtedness is recourse to our Company or our subsidiaries, any requirement in connection with such failure to pay or event of default for the giving of notice or the lapse of time or the happening of any further condition, event or act under such indenture or instrument in connection with such failure to pay or event of default will be applicable together with an additional seven days before being considered an event of default for the purposes of the Indenture;

• certain events involving our bankruptcy, insolvency or reorganization; and

• any other event of default provided for in that series of Debt Securities.

A default under one series of Debt Securities will not necessarily be a default under another series. The trustee may withhold notice to the holders of the Debt Securities of any default, except in the payment of principal or premium, if any, or interest, if any, if in good faith it considers it in the interests of the holders to do so and so advises us in writing.

If an event of default (except for events involving our bankruptcy, insolvency or reorganization) for any series of Debt Securities occurs and continues, the trustee or the holders of at least 25% in aggregate principal amount of the Debt Securities of that series may require us to repay immediately:

• the entire principal and interest of the Debt Securities of the series; or

-19-

• if the Debt Securities are discounted securities, that portion of the principal as is described in the applicable Prospectus Supplement.

If an event of default relates to events involving our bankruptcy, insolvency or reorganization, the principal of all Debt Securities will become immediately due and payable without any action by the trustee or any holder.

Subject to certain conditions, the holders of a majority of the aggregate principal amount of the Debt Securities of the affected series can rescind and annul an accelerated payment requirement. If Debt Securities are discounted securities, the applicable Prospectus Supplement will contain provisions relating to the acceleration of maturity of a portion of the principal amount of the discounted securities upon the occurrence or continuance of an event of default.

Other than its duties in case of a default, the trustee is not obligated to exercise any of the rights or powers that it will have under the Indenture at the request or direction of any holders, unless the holders offer the trustee reasonable security or indemnity. If they provide this reasonable security or indemnity, the holders of a majority in aggregate principal amount of any series of Debt Securities may, subject to certain limitations, direct the time, method and place of conducting any proceeding for any remedy available to the trustee, or exercising any trust or power conferred upon the trustee, for any series of Debt Securities.

We will be required to furnish to the trustee a statement annually as to our compliance with all conditions and covenants under the Indenture and, if we are not in compliance, we must specify any defaults. We will also be required to notify the trustee as soon as practicable upon becoming aware of any event of default.

No holder of a Debt Security of any series will have any right to institute any proceeding with respect to the Indenture, or for the appointment of a receiver or a trustee, or for any other remedy, unless:

• the holder has previously given to the trustee written notice of a continuing event of default with respect to the Debt Securities of the affected series;

• the holders of at least 25% in principal amount of the outstanding Debt Securities of the series affected by an event of default have made a written request, and the holders have offered reasonable indemnity, to the trustee to institute a proceeding as trustee; and

• the trustee has failed to institute a proceeding, and has not received from the holders of a majority in aggregate principal amount of the outstanding Debt Securities of the series affected by an event of default a direction inconsistent with the request, within 60 days after receipt of the holders' notice, request and offer of indemnity.

However, such above-mentioned limitations do not apply to a suit instituted by the holder of a Debt Security for the enforcement of payment of the principal of or any premium, if any, or interest on such Debt Security on or after the applicable due date specified in such Debt Security.

When we use the term "defeasance", it means discharge from our obligations with respect to any Debt Securities of or within a series under the Indenture. Unless otherwise specified in the applicable Prospectus Supplement, if we deposit with the trustee cash, government securities or a combination thereof sufficient to pay the principal, interest, if any, premium, if any, and any other sums due to the stated maturity date or a redemption date of the Debt Securities of a series, then at our option:

• we will be discharged from the obligations with respect to the Debt Securities of that series; or

• we will no longer be under any obligation to comply with certain restrictive covenants under the Indenture and certain events of default will no longer apply to us.

If this happens, the holders of the Debt Securities of the affected series will not be entitled to the benefits of the Indenture except for registration of transfer and exchange of Debt Securities and the replacement of lost, stolen,

-20-

destroyed or mutilated Debt Securities. These holders may look only to the deposited fund for payment on their Debt Securities.

To exercise the defeasance option, we must deliver to the trustee:

• an opinion of counsel in the United States to the effect that the holders of the outstanding Debt Securities of the affected series will not recognize gain or loss for U.S. federal income tax purposes as a result of a defeasance and will be subject to U.S. federal income tax on the same amounts, in the same manner and at the same times as would have been the case if the defeasance had not occurred;

• an opinion of counsel in Canada or a ruling from the Canada Revenue Agency to the effect that the holders of the outstanding Debt Securities of the affected series will not recognize income, gain or loss for Canadian federal, provincial or territorial income or other tax purposes as a result of a defeasance and will be subject to Canadian federal, provincial or territorial income tax and other tax on the same amounts, in the same manner and at the same times as would have been the case had the defeasance not occurred; and

• a certificate of one of our officers and an opinion of counsel, each stating that all conditions precedent provided for relating to defeasance have been complied with.

If we are to be discharged from our obligations with respect to the Debt Securities, and not just from our covenants, the U.S. opinion must be based upon a ruling from or published by the United States Internal Revenue Service or a change in law to that effect.

In addition to the delivery of the opinions described above, the following conditions must be met before we may exercise our defeasance option:

• no event of default or event that, with the passing of time or the giving of notice, or both, shall constitute an event of default shall have occurred and be continuing for the Debt Securities of the affected series;

• we are not an "insolvent person" within the meaning of applicable bankruptcy and insolvency legislation; and

• other customary conditions precedent are satisfied.

Modifications and amendments of the Indenture may be made by our Company and the trustee pursuant to one or more Supplemental Indentures (a "Supplemental Indenture") with the consent of the holders of a majority in aggregate principal amount of the outstanding Debt Securities of each series affected by the modification. However, without the consent of each holder affected, no such modification may:

• change the stated maturity of the principal of, premium, if any, or any installment of interest, if any, on any Debt Security;

• reduce the principal, premium, if any, or rate of interest, if any, or change any obligation of our Company to pay any Additional Amounts;

• reduce the amount of principal of a debt security payable upon acceleration of its maturity or the amount provable in bankruptcy;

• change the place or currency of any payment;

• affect the holder's right to require our Company to repurchase the Debt Securities at the holder's option;

• impair the right of the holders to institute a suit to enforce their rights to payment;

• adversely affect any conversion or exchange right related to a series of Debt Securities;

• reduce the percentage of Debt Securities required to modify the Indenture or to waive compliance with certain provisions of the Indenture; or

-21-

• reduce the percentage in principal amount of outstanding Debt Securities necessary to take certain actions.

The holders of a majority in principal amount of outstanding Debt Securities of any series may on behalf of the holders of all Debt Securities of that series waive, insofar as only that series is concerned, past defaults under the Indenture and compliance by our Company with certain restrictive provisions of the Indenture. However, these holders may not waive a default in any payment of principal, premium, if any, or interest on any Debt Security or compliance with a provision that cannot be modified without the consent of each holder affected.

We may modify the Indenture pursuant to a Supplemental Indenture without the consent of any holders to:

• evidence a successor under the Indenture;

• add covenants or surrender any right or power for the benefit of holders;

• add events of default;

• provide for unregistered securities to become registered securities under the Indenture and make other such changes to unregistered securities that in each case do not materially and adversely affect the interests of holders of outstanding Debt Securities;

• establish the forms of the Debt Securities;

• appoint a successor trustee under the Indenture;

• add provisions to permit or facilitate the defeasance and discharge of the Debt Securities as long as there is no material adverse effect on the holders;

• cure any ambiguity, correct or supplement any defective or inconsistent provision or make any other provisions in each case that would not materially and adversely affect the interests of holders of outstanding Debt Securities, if any;

• comply with any applicable laws of the United States and Canada in order to effect and maintain the qualification of the Indenture under such laws to the extent they do not conflict with the applicable laws of the United States; or

• change or eliminate any provisions of the Indenture where such change takes effect when there are no Debt Securities outstanding under the Indenture.

The Indenture and the Debt Securities will be governed by and construed in accordance with the laws of the State of New York.

Any trustee under the Indenture or its affiliates may provide other services to our Company in the ordinary course of their business. If the trustee or any affiliate acquires any conflicting interest and a default occurs with respect to the Debt Securities, the trustee must eliminate the conflict or resign.

The trustee may resign or be removed with respect to one or more series of the Debt Securities and a successor trustee may be appointed to act with respect to such series.

In connection with the Indenture, we will irrevocably designate and appoint CT Corporation System, 111 8^th Avenue, 13^th Floor, New York, New York 10011, as our Company's authorized agent upon which process may be served in any suit or proceeding arising out of or relating to the Indenture or the Debt Securities that may be

-22-

instituted in any U.S. federal or New York State court located in The Borough of Manhattan, in the City of New York, or brought by the trustee (whether in its individual capacity or in its capacity as trustee under the Indenture), and will irrevocably submit to the non-exclusive jurisdiction of such courts.

Because all or substantially all of our assets, as well as the assets of certain of the directors of our Company, are within the United States, any judgment obtained in Canada against our Company or certain of our directors, including judgments with respect to the payment of principal on the Debt Securities, may not be collectible within Canada.

We have been advised that there is doubt as to the enforceability in the United States, by a court in original actions or actions to enforce judgments of Canadian courts, of civil liabilities predicated solely upon Canadian federal or provincial securities laws.

The following description, together with the additional information we may include in any applicable Prospectus Supplements and free writing prospectuses, summarizes the material terms and provisions of the Warrants that we may offer under this Prospectus, which may consist of Warrants to purchase Common Shares or Debt Securities and may be issued in one or more series. Warrants may be offered independently or together with Common Shares, Debt Securities or Subscription Receipts offered by any Prospectus Supplement, and may be attached to or separate from those Securities. While the terms we have summarized below will apply generally to any Warrants that we may offer under this Prospectus, we will describe the particular terms of any series of Warrants that we may offer in more detail in the applicable Prospectus Supplement and any applicable free writing prospectus. The terms of any Warrants offered under a Prospectus Supplement may differ from the terms described below.

We may also choose to act as our own Warrant Trustee.

This summary of some of the provisions of the Warrants is not complete. The statements made in this Prospectus relating to any Warrant Indenture and Warrants to be issued under this Prospectus are summaries of certain anticipated provisions thereof and do not purport to be complete and are subject to, and are qualified in their entirety by reference to, all provisions of the applicable Warrant Certificate and, if applicable, Warrant Indenture. Prospective investors should refer to the Warrant Certificate and/or Warrant Indenture relating to the specific Warrants being offered for the complete terms of the Warrants. We will file as exhibits to the registration statement of which this Prospectus is a part, or will incorporate by reference from a current report on Form 8-K that we file with the SEC, any Warrant Certificate and/or Warrant Indenture describing the terms and conditions of Warrants we are offering before the issuance of such Warrants.

The applicable Prospectus Supplement relating to any Warrants offered by our Company will describe the particular terms of those Warrants and include specific terms relating to the offering.

• any other material terms or conditions of the Debt Warrants.

Prior to the exercise of their Warrants, holders of Warrants will not have any of the rights of holders of the Common Shares or Debt Securities issuable upon exercise of the Warrants.

Each Warrant will entitle the holder to purchase the Securities that we specify in the applicable Prospectus Supplement at the exercise price that we describe therein. Unless we otherwise specify in the applicable Prospectus Supplement, holders of the Warrants may exercise the Warrants at any time up to the specified time on the expiration date that we set forth in the applicable Prospectus Supplement. After the close of business on the expiration date, unexercised Warrants will become void.

Holders of the Warrants may exercise the Warrants by delivering the Warrant Certificate representing the Warrants to be exercised together with specified information, and paying the required amount to our Company or, if applicable, the Warrant Trustee, in immediately available funds, as provided in the applicable Prospectus Supplement. We will set forth on the Warrant Certificate and in the applicable Prospectus Supplement the information that the holder of the Warrant will be required to deliver to our Company or, if applicable, the Warrant Trustee.

Upon receipt of the required payment and the Warrant Certificate properly completed and duly executed at our Company or, if applicable, the corporate trust office of the Warrant Trustee or any other office indicated in the applicable Prospectus Supplement, we will issue and deliver the securities purchasable upon such exercise. If fewer than all of the Warrants represented by the Warrant Certificate are exercised, then we will issue a new Warrant Certificate for the remaining amount of Warrants. If we so indicate in the applicable Prospectus Supplement, holders of the Warrants may surrender securities as all or part of the exercise price for Warrants.

The Warrant Certificate and/or Warrant Indenture will specify that upon the subdivision, consolidation, reclassification or other material change of the Common Shares or Debt Securities or any other reorganization, amalgamation, merger or sale of all or substantially all of our assets, the Warrants will thereafter evidence the right of the holder to receive the securities, property or cash deliverable in exchange for or on the conversion of or in respect of the Common Shares or Debt Securities to which the holder of a Common Share or Debt Security would have been entitled immediately after such event. Similarly, any distribution to all or substantially all of the holders of Common Shares of rights, options, warrants, evidences of indebtedness or assets will result in an adjustment in the number of Common Shares to be issued to holders of Equity Warrants.

We may issue Warrants in whole or in part in the form of one or more global securities, which will be registered in the name of and be deposited with a depositary, or its nominee, each of which will be identified in the applicable Prospectus Supplement. The global securities may be in temporary or permanent form. The applicable Prospectus Supplement will describe the terms of any depositary arrangement and the rights and limitations of owners of beneficial interests in any global security. The applicable Prospectus Supplement will describe the exchange, registration and transfer rights relating to any global security.

The Warrant Certificate and/or Warrant Indenture will provide for modifications and alterations to the Warrants issued thereunder by way of a resolution of holders of Warrants at a meeting of such holders or a consent in writing from such holders. The number of holders of Warrants required to pass such a resolution or execute such a written consent will be specified in the Warrant Certificate and/or Warrant Indenture.

-25-

We may amend any Warrant Certificate and/or Warrant Indenture and the Warrants, without the consent of the holders of the Warrants, to cure any ambiguity, to cure, correct or supplement any defective or inconsistent provision, or in any other manner that will not materially and adversely affect the interests of holders of outstanding Warrants.

We may issue Subscription Receipts, which will entitle holders to receive upon satisfaction of certain release conditions and for no additional consideration, Common Shares, Debt Securities, Warrants or any combination thereof. Subscription Receipts will be issued pursuant to one or more subscription receipt agreements (each, a "Subscription Receipt Agreement"), each to be entered into between our Company and an escrow agent (the "Escrow Agent"), which will establish the terms and conditions of the Subscription Receipts. Each Escrow Agent will be a financial institution organized under the laws of the United States or a state thereof or Canada or a province thereof and authorized to carry on business as an escrow agent. We will file as exhibits to the registration statement of which this Prospectus is a part, or will incorporate by reference from a current report on Form 8-K that we file with the SEC, any Subscription Receipt Agreement describing the terms and conditions of Subscription Receipts we are offering before the issuance of such Subscription Receipts.

The following description sets forth certain general terms and provisions of Subscription Receipts and is not intended to be complete. The statements made in this Prospectus relating to any Subscription Receipt Agreement and Subscription Receipts to be issued thereunder are summaries of certain anticipated provisions thereof and are subject to, and are qualified in their entirety by reference to, all provisions of the applicable Subscription Receipt Agreement and the Prospectus Supplement describing such Subscription Receipt Agreement.

The Prospectus Supplement relating to any Subscription Receipts we offer will describe the Subscription Receipts and include specific terms relating to their offering. All such terms will comply with the requirements of NYSE Amex relating to Subscription Receipts. If underwriters or agents are used in the sale of Subscription Receipts, one or more of such underwriters or agents may also be parties to the Subscription Receipt Agreement governing the Subscription Receipts sold to or through such underwriters or agents.

The Prospectus Supplement and the Subscription Receipt Agreement for any Subscription Receipts we offer will describe the specific terms of the Subscription Receipts and may include, but are not limited to, any of the following:

• the designation and aggregate number of Subscription Receipts offered;

• the price at which the Subscription Receipts will be offered;

• the currency or currencies in which the Subscription Receipts will be offered;

• the designation, number and terms of the Common Shares, Debt Securities, Warrants or combination thereof to be received by holders of Subscription Receipts upon satisfaction of the release conditions, and the procedures that will result in the adjustment of those numbers;

• the conditions (the "Release Conditions") that must be met in order for holders of Subscription Receipts to receive for no additional consideration Common Shares, Debt Securities, Warrants or a combination thereof;

• the procedures for the issuance and delivery of Common Shares, Debt Securities, Warrants or a combination thereof to holders of Subscription Receipts upon satisfaction of the Release Conditions;

• whether any payments will be made to holders of Subscription Receipts upon delivery of the Common Shares, Debt Securities, Warrants or a combination thereof upon satisfaction of the Release Conditions (e.g., an amount equal to dividends declared on Common Shares by our Company to holders of record during the period from the date of issuance of the Subscription Receipts to the date of issuance of any Common Shares pursuant to the terms of the Subscription Receipt Agreement, or an amount equal to interest payable by our Company in respect of Debt Securities during the period from the date of issuance of the Subscription Receipts to the date of issuance of the Debt Securities pursuant to the terms of the Subscription Receipt Agreement);

-26-

• the terms and conditions under which the Escrow Agent will hold all or a portion of the gross proceeds from the sale of Subscription Receipts, together with interest and income earned thereon (collectively, the "Escrowed Funds"), pending satisfaction of the Release Conditions;

• the terms and conditions pursuant to which the Escrow Agent will hold Common Shares, Debt Securities, Warrants or a combination thereof pending satisfaction of the Release Conditions;

• the terms and conditions under which the Escrow Agent will release all or a portion of the Escrowed Funds to our Company upon satisfaction of the Release Conditions;

• if the Subscription Receipts are sold to or through underwriters or agents, the terms and conditions under which the Escrow Agent will release a portion of the Escrowed Funds to such underwriters or agents in payment of all or a portion of their fees or commission in connection with the sale of the Subscription Receipts;

• procedures for the refund by the Escrow Agent to holders of Subscription Receipts of all or a portion of the subscription price for their Subscription Receipts, plus any pro rata entitlement to interest earned or income generated on such amount, if the Release Conditions are not satisfied;

• any entitlement of our Company to purchase the Subscription Receipts in the open market by private agreement or otherwise;

• whether we will issue the Subscription Receipts as global securities and, if so, the identity of the depositary for the global securities;

• whether we will issue the Subscription Receipts as bearer securities, registered securities or both;

• provisions as to modification, amendment or variation of the Subscription Receipt Agreement or any rights or terms attaching to the Subscription Receipts;

• the identity of the Escrow Agent;

• whether the Subscription Receipts will be listed on any exchange;

• material United States and Canadian federal tax consequences of owning the Subscription Receipts; and

• any other terms of the Subscription Receipts.

In addition, the Prospectus Supplement and the Subscription Receipt Agreement for any Subscription Receipts we offer will describe all contractual rights of rescission that will be granted to initial purchasers of Subscription Receipts in the event this Prospectus, the Prospectus Supplement under which Subscription Receipts are issued or any amendment hereto or thereto contains a misrepresentation, as discussed further under the sub-paragraph entitled "Rescission" below.

The Escrowed Funds will be held in escrow by the Escrow Agent, and such Escrowed Funds will be released to our Company (and, if the Subscription Receipts are sold to or through underwriters or agents, a portion of the Escrowed

-27-

Funds may be released to such underwriters or agents in payment of all or a portion of their fees in connection with the sale of the Subscription Receipts) at the time and under the terms specified by the Subscription Receipt Agreement. If the Release Conditions are not satisfied, holders of Subscription Receipts will receive a refund of all or a portion of the subscription price for their Subscription Receipts plus their pro rata entitlement to interest earned or income generated on such amount, in accordance with the terms of the Subscription Receipt Agreement. Common Shares, Debt Securities or Warrants may be held in escrow by the Escrow Agent, and will be released to the holders of Subscription Receipts following satisfaction of the Release Conditions at the time and under the terms specified in the Subscription Receipt Agreement.

The Subscription Receipt Agreement will specify that upon the subdivision, consolidation, reclassification or other material change of the Common Shares, Debt Securities or Warrants or any other reorganization, amalgamation, merger or sale of all or substantially all of our assets, the Subscription Receipts will thereafter evidence the right of the holder to receive the securities, property or cash deliverable in exchange for or on the conversion of or in respect of the Common Shares, Debt Securities or Warrants to which the holder of a Common Share, Debt Security or Warrant would have been entitled immediately after such event. Similarly, any distribution to all or substantially all of the holders of Common Shares of rights, options, warrants, evidences of indebtedness or assets will result in an adjustment in the number of Common Shares to be issued to holders of Subscription Receipts whose Subscription Receipts entitle the holders thereof to receive Common Shares. Alternatively, such securities, evidences of indebtedness or assets may, at the option of our Company, be issued to the Escrow Agent and delivered to holders of Subscription Receipts on exercise thereof. The Subscription Receipt Agreement will also provide that if other actions of our Company affect the Common Shares, Debt Securities or Warrants, which, in the reasonable opinion of the directors of our Company, would materially affect the rights of the holders of Subscription Receipts and/or the rights attached to the Subscription Receipts, the number of Common Shares, Debt Securities or Warrants which are to be received pursuant to the Subscription Receipts shall be adjusted in such manner, if any, and at such time as our directors may in their discretion reasonably determine to be equitable to the holders of Subscription Receipts in such circumstances.

The Subscription Receipt Agreement will also provide that any misrepresentation in this Prospectus, the Prospectus Supplement under which the Subscription Receipts are offered, or any amendment thereto, will entitle each initial purchaser of Subscription Receipts to a contractual right of rescission following the issuance of the Common Shares, Debt Securities or Warrants to such purchaser entitling such purchaser to receive the amount paid for the Subscription Receipts upon surrender of the Common Shares, Debt Securities or Warrants, provided that such remedy for rescission is exercised in the time stipulated in the Subscription Receipt Agreement. This right of rescission does not extend to holders of Subscription Receipts who acquire such Subscription Receipts from an initial purchaser, on the open market or otherwise, or to initial purchasers who acquire Subscription Receipts in the United States.

We may issue Subscription Receipts in whole or in part in the form of one or more global securities, which will be registered in the name of and be deposited with a depositary, or its nominee, each of which will be identified in the applicable Prospectus Supplement. The global securities may be in temporary or permanent form. The applicable Prospectus Supplement will describe the terms of any depositary arrangement and the rights and limitations of owners of beneficial interests in any global security. The applicable Prospectus Supplement also will describe the exchange, registration and transfer rights relating to any global security.

The Subscription Receipt Agreement will provide for modifications and alterations to the Subscription Receipts issued thereunder by way of a resolution of holders of Subscription Receipts at a meeting of such holders or a consent in writing from such holders. The number of holders of Subscriptions Receipts required to pass such a resolution or execute such a written consent will be specified in the Subscription Receipt Agreement.

The following description, together with the additional information we may include in any applicable Prospectus Supplements, summarizes the material terms and provisions of the Units that we may offer under this Prospectus. While the terms we have summarized below will apply generally to any Units that we may offer under this Prospectus, we will describe the particular terms of any series of Units in more detail in the applicable Prospectus Supplement. The terms of any Units offered under a Prospectus Supplement may differ from the terms described below.

We will file as exhibits to the registration statement of which this Prospectus is a part, or will incorporate by reference from a current report on Form 8-K that we file with the SEC, the form of unit agreement, if any ("Unit Agreement"), between our Company and a unit agent, if any ("Unit Agent"), that describes the terms and conditions of the series of Units we are offering, and any supplemental agreements, before the issuance of the related series of Units. We may also choose to act as our own Unit Agent. The following summaries of material terms and provisions of the Units are subject to, and qualified in their entirety by reference to, all the provisions of the Unit Agreement, if applicable, and any supplemental agreements applicable to a particular series of Units. We urge you to read the applicable Prospectus Supplements related to the particular series of Units that we sell under this Prospectus, as well as the complete Unit Agreement, if applicable, and any supplemental agreements that contain the terms of the Units.

We may issue units comprising one or more of Common Shares, Debt Securities, Warrants and Subscription Receipts in any combination. Each Unit will be issued so that the holder of the Unit is also the holder of each security included in the Unit. Thus, the holder of a Unit will have the rights and obligations of a holder of each included security. The Unit Agreement, if applicable, under which a Unit is issued may provide that the securities included in the Unit may not be held or transferred separately, at any time or at any time before a specified date.

We will describe in the applicable Prospectus Supplement the terms of the series of Units, including:

• the designation and terms of the Units and of the securities comprising the Units, including whether and under what circumstances those securities may be held or transferred separately;

• if applicable, any provisions of the governing Unit Agreement that differ from those described below; and

• any provisions for the issuance, payment, settlement, transfer or exchange of the Units or of the securities comprising the Units.

The provisions described in this section, as well as those described under "Description of Common Shares," "Description of Debt Securities," "Description of Warrants," and "Description of Subscription Receipts" will apply to each Unit and to any Common Share, Debt Security, Warrant or Subscription Receipt included in each Unit, respectively.

We may issue Units in such amounts and in numerous distinct series as we determine.

Each Unit Agent, if applicable, will act solely as our agent under the applicable Unit Agreement, if any, and will not assume any obligation or relationship of agency or trust with any holder of any Unit. A single bank or trust company may act as Unit Agent for more than one series of Units. A Unit Agent will have no duty or responsibility in case of any default by our Company under the applicable Unit Agreement, if any, or Unit, including any duty or responsibility to initiate any proceedings at law or otherwise, or to make any demand upon our Company. Any holder of a Unit may, without the consent of the related Unit Agent, if applicable, or the holder of any other Unit, enforce by appropriate legal action its rights as holder under any security included in the Unit.

Our Company, any Unit Agent, and any of their agents may treat the registered holder of any Unit Certificate as an absolute owner of the Units evidenced by that certificate for any purpose and as the person entitled to exercise the rights attaching to the Units so requested, despite any notice to the contrary.

-29-

We may offer and sell the Securities, separately or together: (a) to one or more underwriters or dealers; (b) through one or more agents; or (c) directly to one or more other purchasers. The Securities offered pursuant to any Prospectus Supplement may be sold from time to time in one or more transactions at: (i) a fixed price or prices, which may be changed from time to time; (ii) market prices prevailing at the time of sale; (iii) prices related to such prevailing market prices; or (iv) other negotiated prices. We may only offer and sell the Securities pursuant to a Prospectus Supplement during the period that this Prospectus, including any amendments hereto, remains effective. The Prospectus Supplement for any of the Securities being offered thereby will set forth the terms of the offering of such Securities, including the type of Security being offered, the name or names of any underwriters, dealers or agents, the purchase price of such Securities, the proceeds to our Company from such sale, any underwriting commissions or discounts and other items constituting underwriters' compensation and any discounts or concessions allowed or re-allowed or paid to dealers. Only underwriters so named in the Prospectus Supplement are deemed to be underwriters in connection with the Securities offered thereby.

If underwriters are used in the sale, the Securities will be acquired by the underwriters for their own account and may be resold from time to time in one or more transactions, including negotiated transactions, at a fixed public offering price or at varying prices determined at the time of sale. Unless otherwise set forth in the Prospectus Supplement relating thereto, the obligations of underwriters to purchase the Securities will be subject to certain conditions, but the underwriters will be obligated to purchase all of the Securities offered by the Prospectus Supplement if any of such Securities are purchased. We may offer the Securities to the public through underwriting syndicates represented by managing underwriters or by underwriters without a syndicate. We may agree to pay the underwriters a fee or commission for various services relating to the offering of any Securities. Any such fee or commission will be paid out of the general corporate funds of our Company. We may use underwriters with whom we have a material relationship. We will describe in the Prospectus Supplement, naming the underwriter, the nature of any such relationship.

If dealers are used, and if so specified in the applicable Prospectus Supplement, we will sell such Securities to the dealers as principals. The dealers may then resell such Securities to the public at varying prices to be determined by such dealers at the time of resale. Any public offering price and any discounts or concessions allowed or re-allowed or paid to dealers may be changed from time to time. We will set forth the names of the dealers and the terms of the transaction in the applicable Prospectus Supplement.

The Securities may also be sold through agents designated by our Company. Any agent involved will be named, and any fees or commissions payable by our Company to such agent will be set forth, in the applicable Prospectus Supplement. Any such fees or commissions will be paid out of the general corporate funds of our Company. Unless otherwise indicated in the Prospectus Supplement, any agent will be acting on a best efforts basis for the period of its appointment.

Securities may also be sold directly by our Company at such prices and upon such terms as agreed to by our Company and the purchaser. In this case, no underwriters, dealers or agents would be involved in the offering.

Underwriters, dealers and agents that participate in the distribution of the Securities offered by this Prospectus may be deemed underwriters under the Securities Act, and any discounts or commissions they receive from us and any profit on their resale of the securities may be treated as underwriting discounts and commissions under the Securities Act.

-30-

Underwriters, dealers or agents who participate in the distribution of Securities may be entitled under agreements to be entered into with our Company to indemnification by our Company against certain liabilities, including liabilities under Canadian provincial and territorial and United States securities legislation, or to contribution with respect to payments which such underwriters, dealers or agents may be required to make in respect thereof. Such underwriters, dealers or agents may be customers of, engage in transactions with, or perform services for, our Company in the ordinary course of business.

We may enter into derivative transactions with third parties, or sell securities not covered by this Prospectus to third parties in privately negotiated transactions. If the applicable Prospectus Supplement indicates, in connection with those derivatives, the third parties may sell securities covered by this Prospectus and the applicable Prospectus Supplement, including in short sale transactions. If so, the third parties may use securities pledged by us or borrowed from us or others to settle those sales or to close out any related open borrowings of stock, and may use securities received from us in settlement of those derivatives to close out any related open borrowings of stock. The third parties in such sale transactions will be identified in the applicable Prospectus Supplement.

One or more firms, referred to as "remarketing firms," may also offer or sell the Securities, if the Prospectus Supplement so indicates, in connection with a remarketing arrangement upon their purchase. Remarketing firms will act as principals for their own accounts or as agents for us. These remarketing firms will offer or sell the Securities in accordance with the terms of the Securities. The Prospectus Supplement will identify any remarketing firm and the terms of its agreement, if any, with us and will describe the remarketing firm's compensation. Remarketing firms may be deemed to be underwriters in connection with the Securities they remarket.

In connection with any offering of Securities, underwriters may over-allot or effect transactions which stabilize or maintain the market price of the Securities offered at a level above that which might otherwise prevail in the open market. Such transactions may be commenced, interrupted or discontinued at any time.

The following is a general summary of certain U.S. federal income tax considerations that may be relevant to U.S. holders and Non-U.S. holders (as defined below) with respect to the acquisition, ownership and disposition of Debt Securities and Common Shares acquired pursuant to this Prospectus. It does not address the United States federal income tax consequences of the purchase, ownership, and exercise of Warrants, Subscription Receipts, or Units.

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 IRS, published administrative positions of the IRS, and United States court decisions that are applicable and, in each case, as in effect and available, as of the date of this Prospectus. Any of the authorities on which this summary is based could be changed in a material and adverse manner at any time, and any such change could be applied on a retroactive basis. This summary does not discuss the potential effects, whether adverse or beneficial, of any proposed legislation that, if enacted, could be applied on a retroactive basis.

This summary is for general information purposes only and does not purport to be a complete analysis or listing of all potential United States federal income tax consequences related to the acquisition, ownership and disposition of Debt Securities or Common Shares. In addition, this summary does not address other United States federal tax laws, such as estate and gift tax laws, and does not address any state, local, or foreign tax consequences.

This summary deals only with persons or entities that hold our Debt Securities or Common Shares as a capital asset within the meaning of Section 1221 of the Code. This summary does not address all aspects of U.S. federal income taxation that may be applicable to holders subject to special treatment under U.S. federal income tax law, such as (without limitation): banks, insurance companies, and other financial institutions; dealers in securities or foreign currencies; regulated investment companies; traders in securities that mark to market; U.S. expatriates or former long-term residents of the U.S.; persons holding Common Shares as part of a straddle, appreciated financial position,

-31-

synthetic security, hedge, conversion transaction or other integrated investment; persons holding Common Shares as a result of a constructive sale; persons holding Debt Securities or Common Shares whose functional currency is not the U.S. dollar; persons who directly, indirectly, or by attribution own 10% or more of our outstanding equity interests; or entities that acquire Common Shares that are treated as partnerships for U.S. federal income tax purposes and investors (i.e., partners) in such partnerships. Holders that are subject to special provisions under the Code, including holders described immediately above, should consult their own tax advisor regarding the United States federal, state and local, and foreign tax consequences arising from and relating to the acquisition, ownership and disposition of Common Shares.

This summary does not take into account the individual facts and circumstances of any particular holder that may affect the United States federal income tax consequences to such holder (e.g., application of the alternative minimum tax). Accordingly, this summary is not intended to be, and should not be construed as, legal or United States federal income tax advice with respect to any holder. Each holder should consult its own tax advisor regarding the United States federal, state and local, and foreign tax consequences related to the acquisition, ownership and disposition of Common Shares.

If an entity treated as a partnership holds our Common Shares, the tax treatment of the partners and the partnership generally will depend on the status of the partner and the activities of the partnership. If you are a partner of a partnership holding our Common Shares, you should consult your own tax advisor.

This summary is not intended and was not written to be used, and cannot be used, by any taxpayer for the purpose of avoiding penalties under the United States federal tax laws that may be imposed on the taxpayer.

No legal opinion from United States legal counsel or ruling from the Internal Revenue Service (the "IRS") has been requested, or will be obtained, regarding the United States federal income tax consequences related to 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.

As used in this summary, the term "U.S. Holder" means a beneficial owner of Debt Securities or Common Shares acquired pursuant to this Prospectus that is for U.S. federal income tax purposes: an individual who is a citizen or resident of the U.S.; a corporation (or other entity taxable as a corporation) organized under the laws of the U.S., any state thereof or the District of Columbia; an estate whose income is subject to U.S. federal income taxation regardless of its source; or a trust that (1) is subject to the primary supervision of a court within the U.S. and one or more U.S. persons have the authority to control all substantial decisions of the trust or (2) has a valid election in effect under applicable U.S. Treasury regulations to be treated as a U.S. person.

The term "Non-U.S. Holder" means any beneficial owner of Debt Securities or Common Shares acquired pursuant to this Prospectus that is neither a U.S. Holder nor a partnership nor other entity or arrangement treated as a partnership for U.S. federal income tax purposes. A Non-U.S. Holder should review the discussion under the headings "Additional Amounts Paid with Respect to Debt Securities," "Tax Redemptions," and "U.S. Federal Income Tax Consequences to Non-U.S. Holders of the Acquisition, Ownership and Disposition of Common Shares" below for more information.

Interest on a Debt Security generally will be taxable to a U.S. Holder as ordinary interest income at the time of receipt or accrual in accordance with the U.S. Holder's method of accounting for U.S. federal income tax purposes.

-32-

Repayments of the principal amount of a Debt Security are not subject to U.S. federal income tax.

Except to the extent that gain or loss is attributable to accrued but unpaid interest, a U.S. Holder generally will recognize capital gain or loss upon a sale, exchange or complete retirement of a Debt Security equal to the difference between the amount realized and the U.S. Holder's adjusted basis in the Debt Security. The gain or loss generally will be long-term if the Debt Security has been held for more than one year. The adjusted basis of a Debt Security generally will equal its initial cost reduced by principal payments previously received on the Debt Security.

Unless otherwise specified in the applicable Prospectus Supplement, all payments made by or on behalf of our Company under or with respect to the Debt Securities of any series will be made free and clear of and without withholding or deduction for or on account of any present or future tax, duty, levy, impost, assessment or other government charge (including penalties, interest and other liabilities related thereto) imposed or levied by or on behalf of the U.S. Government or by any authority or agency therein or thereof having power to tax ("U.S. Taxes"), unless we are required to withhold or deduct U.S. Taxes by law or by the interpretation or administration thereof by the relevant government authority or agency.

If we are so required to withhold or deduct any amount for or on account of U.S. Taxes from any payment made under or with respect to the Debt Securities issued, we will pay, unless otherwise specified, as additional interest such additional amounts, (the "Additional Amounts"), as may be necessary so that the net amount received by a holder of the Debt Securities after such withholding or deduction will not be less than the amount such holder of the Debt Securities would have received if such U.S. Taxes had not been withheld or deducted (a similar payment will also be made to holders of the Debt Securities, other than excluded holders (as defined herein), that are exempt from withholding but required to pay tax under the Code, directly on amounts otherwise subject to withholding); provided, however, that no additional amounts will be payable with respect to a payment made to a holder (an "excluded holder") if the holder of the Debt Securities or the beneficial owner of some or all of the payment to the holder:

• does not deal at arm's length with our Company (for purposes of the Code) at the time of the making of such payment;

• is subject to such U.S. Taxes by reason of the Debt Securities holder's failure to comply with any certification, identification, information, documentation or other reporting requirement if compliance is required by law, regulation, administrative practice or an applicable treaty as a precondition to exemption from, or a reduction in the rate of deduction or withholding of, such U.S. Taxes;

• is subject to such U.S. Taxes by reason of the Debt Securities holder being a resident, domicile or national of, or engaged in business or maintaining a permanent establishment or other physical presence in or otherwise having some connection with the U.S. otherwise than by the mere holding of the Debt Securities or the receipt of payments thereunder; or

• is subject to such U.S. Taxes because it is not entitled to the benefit of an otherwise applicable tax treaty by reason of the legal nature of such holder of the Debt Securities.

We will make such withholding or deduction and remit the full amount deducted or withheld to the relevant authority as and when required in accordance with applicable law. We will pay all taxes, interest and other liabilities which arise by virtue of any failure of our Company to withhold, deduct and remit to the relevant authority on a timely basis the full amounts required in accordance with applicable law. We will furnish to the holder of the Debt Securities subject to withholding or deduction, within 60 days after the date the payment of any U.S. Taxes is due pursuant to applicable law, certified copies of tax receipts evidencing such payment by us.

The foregoing obligations shall survive any termination, defeasance or discharge of the Indenture.

-33-

If and to the extent specified in the applicable Prospectus Supplement, the Debt Securities issued of a series will be subject to redemption at any time, in whole but not in part, at a redemption price equal to the principal amount thereof together with accrued and unpaid interest to the date fixed for redemption, upon the giving of a notice, if (1) we determine that (a) as a result of any change in or amendment to the laws (or any regulations or rulings promulgated thereunder) of the U.S. or of any political subdivision or taxing authority thereof or therein affecting taxation, or any change in position regarding application or interpretation of such laws, regulations or rulings (including a holding by a court of competent jurisdiction), which change or amendment is announced or becomes effective on or after a date specified in the applicable Prospectus Supplement if any date is so specified, we have or will become obligated to pay, on the next succeeding date on which interest is due, Additional Amounts with respect to any Debt Security of such series or (b) on or after a date specified in the applicable Prospectus Supplement, any action has been taken by any taxing authority of, or any decision has been rendered by a court of competent jurisdiction in, the U.S. or any political subdivision or taxing authority thereof or therein, including any of those actions specified in (a) above, whether or not such action was taken or decision was rendered with respect to our Company, or any change, amendment, application or interpretation shall be proposed, which, in any such case, in the opinion of counsel to our Company, will result in our becoming obligated to pay, on the next succeeding date on which interest is due, Additional Amounts with respect to any Debt Security issued of such series and (2) in any such case, our Company, in our business judgment, determines that such obligation cannot be avoided by the use of reasonable measures available to it; provided however, that (i) no such notice of redemption may be given earlier than 90 days prior to the earliest date on which we would be obligated to pay such Additional Amounts were a payment in respect of the Debt Securities then due, and (ii) at the time such notice of redemption is given, such obligation to pay such Additional Amounts remains in effect.

In the event that we elect to redeem the Debt Securities issued of such series pursuant to the provisions set forth in the preceding paragraph, we shall deliver to the trustee a certificate, signed by an authorized officer, stating that we are entitled to redeem the Debt Securities issued of such series pursuant to their terms.

Distributions made on our Common Shares generally will be included in a U.S. Holder's income as ordinary dividend income to the extent of our current and accumulated earnings and profits (determined under U.S. federal income tax principles) as of the end of our taxable year in which the distribution occurs. However, with respect to dividends received by individuals, for taxable years beginning before January 1, 2013, such dividends are generally taxed at the lower applicable long-term capital gains rates, provided certain holding period requirements are satisfied. Distributions in excess of our current and accumulated earnings and profits will be treated as a return of capital to the extent of a U.S. Holder's adjusted tax basis in the Common Shares and thereafter as capital gain from the sale or exchange of such Common Shares. Dividends received by a corporation may be eligible for a dividends received deduction, subject to applicable limitations.

Upon the sale, certain qualifying redemptions, or other taxable disposition of our Common Shares, a U.S. Holder generally will recognize capital gain or loss equal to the difference between (i) the amount of cash and the fair market value of any property received upon such taxable disposition and (ii) the U.S. Holder's adjusted tax basis in the Common Shares. Such capital gain or loss will be long-term capital gain or loss if a U.S. Holder's holding period in the Common Shares is more than one year at the time of the taxable disposition. Long-term capital gains recognized by certain non-corporate U.S. Holders (including individuals) will generally be subject to a maximum U.S. federal income tax rate of 15%, which maximum is currently scheduled to increase to 20% for dispositions occurring during taxable years beginning on or after January 1, 2013. The deductibility of capital losses is subject to limitations. A U.S. Holder who sells Common Shares at a loss which, in the aggregate, exceeds certain thresholds may also be required to file a disclosure statement with the IRS.

-34-

Information reporting requirements generally will apply to payments of dividends on our Common Shares and to the proceeds of a sale of Common Shares paid to a U.S. Holder unless the U.S. Holder is an exempt recipient. A backup withholding tax will apply to those payments if the U.S. Holder fails to provide its correct taxpayer identification number, or certification of exempt status, or if the U.S. Holder is notified by the IRS that it has failed to report in full payments of interest and dividend income. Any amounts withheld under the backup withholding rules will be allowed as a refund or a credit against a U.S. Holder's U.S. federal income tax liability provided the required information is furnished in a timely manner to the IRS.

Distributions on our Common Shares will constitute dividends for U.S. tax purposes to the extent paid from our current and accumulated earnings and profits, as determined under U.S. federal income tax principles. To the extent those distributions exceed our current and accumulated earnings and profits, they will constitute a return of capital and will first reduce a Non-U.S. Holder's basis in our Common Shares, but not below zero, and then will be treated as gain from the sale of stock, which will be taxable according to rules discussed under the heading "Sale or Exchange of Common Shares," below. Any dividends paid to a Non-U.S. Holder with respect to our Common Shares generally will be subject to withholding tax at a 30% gross rate, subject to any exemption or lower rate under an applicable treaty if the Non-U.S. Holder provides us with a properly executed IRS Form W-8BEN, unless the Non-U.S. Holder provides us with a properly executed IRS Form W-8ECI (or other applicable form) relating to income effectively connected with the conduct of a trade or business within the U.S.

Dividends that are effectively connected with the conduct of a trade or business within the U.S. and includible in the Non-U.S. Holder's gross income are not subject to the withholding tax (assuming proper certification and disclosure), but instead are subject to U.S. federal income tax on a net income basis at applicable graduated individual or corporate rates. Any such effectively connected income received by a foreign corporation may, under certain circumstances, be subject to an additional branch profits tax at a 30% rate, subject to any exemption or lower rate as may be specified by an applicable income tax treaty.

A Non-U.S. Holder of Common Shares who wishes to claim the benefit of an applicable treaty rate or exemption is required to satisfy certain certification and other requirements. If a Non-U.S. Holder is eligible for an exemption from or a reduced rate of U.S. withholding tax pursuant to an income tax treaty, it may obtain a refund of any excess amounts withheld by timely filing an appropriate claim for refund with the IRS.

In general, a Non-U.S. Holder of Common Shares will not be subject to U.S. federal income tax on gain recognized from a sale, exchange, or other taxable disposition of such Common Shares, unless:

• the gain is effectively connected with a U.S. trade or business carried on by the Non-U.S. Holder (and, where an income tax treaty applies, is attributable to U.S. permanent establishment of the Non-U.S. Holder), in which case the Non-U.S. Holder will be subject to tax on the net gain from the sale at regular graduated federal income tax rates, and if the Non-U.S. Holder is a corporation may be subject to branch profits tax, as described below;

• the Non-U.S. Holder is an individual who is present in the U.S. for 183 days or more in the taxable year of disposition, in which case the Non-U.S. Holder will be subject to a 30% tax on the gain from the sale, which may be offset by U.S. source capital losses; or

• Our Company is or has been a "U.S. real property holding corporation" ("USRPHC") for U.S. federal income tax purposes at any time during the shorter of the Non-U.S. Holder's holding period or the 5-year period ending on the date of disposition of Common Shares; provided, that as long as our shares of Common Shares are regularly traded on an established securities market (the "Regularly Traded Exception"), a Non-U.S. Holder would not be subject to taxation under this rule if the Non-U.S. Holder has

If a Non-U.S. Holder is an individual described in the first bullet point above, he or she will be subject to tax on the net gain derived from the sale or other taxable disposition of our Common Shares under regular graduated U.S. federal income tax rates. If a Non-U.S. Holder is a foreign corporation described in the first bullet point above, it will be subject to tax on its net gain from such a sale or other taxable disposition generally in the same manner as if it were a U.S. person as defined under the Code and, in addition, it may be subject to the branch profits tax at a gross rate equal to 30% of its effectively connected earnings and profits for that taxable year, subject to any exemption or lower rate as may be specified by an applicable income tax treaty. If a Non-U.S. Holder is an individual described in the second bullet point above, such holder will be subject to tax at a rate of 30% (or subject to any exemption or lower rate as may be specified by an applicable income tax treaty) on the gain derived from the sale or other taxable disposition of our Common Shares even though such holder is not considered a resident of the U.S. The amount of such gain may be offset by the Non-U.S. Holder's U.S. source capital losses.

Generally, we must report annually to the IRS and to Non-U.S. Holders the amount of dividends paid on our Common Shares to Non-U.S. Holders and the amount of tax, if any, withheld with respect to those payments. Copies of the information returns reporting such interest, dividends and withholding may also be made available to the tax authorities in the country in which a Non-U.S. Holder resides under the provisions of an applicable income tax treaty.

In general, a Non-U.S. Holder will not be subject to backup withholding with respect to payments of dividends that we make, provided we receive a statement meeting certain requirements to the effect that the Non-U.S. Holder is not a U.S. person and we do not have actual knowledge or reason to know that the holder is a U.S. person, as defined under the Code, that is not an exempt recipient. The requirements for the statement will be met if (1) the Non-U.S. Holder provides its name, address and U.S. taxpayer identification number, if any, and certifies, under penalty of perjury, that it is not a U.S. person (which certification may be made on IRS Form W-8BEN) or (2) a financial institution holding the instrument on behalf of the Non-U.S. Holder certifies, under penalty of perjury, that such statement has been received by it and furnishes us or our paying agent, if applicable, with a copy of the statement. In addition, a Non-U.S. Holder will be subject to information reporting and, depending on the circumstances, backup withholding with respect to payments of the proceeds of a sale of our Common Shares within the U.S. or conducted through certain U.S.-related financial intermediaries, unless the statement described above has been received, and we do not have actual knowledge or reason to know that a holder is a U.S. person, as defined under the Code, that is not an exempt recipient, or the Non-U.S. Holder otherwise establishes an exemption. Any amounts withheld under the backup withholding rules will be allowed as a refund or a credit against a Non-U.S. Holder's U.S. federal income tax liability provided the required information is furnished timely to the IRS.
