Common Shares

Warrants

Units
_____________

Largo Inc. (“we”, “us”, “our”, “Largo” or the “Company”) may offer and issue from time to time common shares (“Common Shares”), common share purchase warrants (“Warrants”) and units comprised of Common Shares and Warrants (“Units”) or any combination thereof (collectively, the “Securities”) up to an aggregate initial offering price of $150,000,000 (or the equivalent thereof if the Securities are denominated in any other currency or currency unit) during the period that this registration statement (the “Registration Statement”), including any amendments thereto, remains effective. Securities may be offered separately or together, in amounts, at prices and on terms to be determined based on market conditions at the time of sale and set forth in one or more prospectus supplements (each, a “Prospectus Supplement” and together, the “Prospectus Supplements”) to the prospectus contained in the Registration Statement (the “Prospectus”).

The specific terms of the Securities with respect to a particular offering will be set out in the applicable Prospectus Supplement and may include, where applicable (i) in the case of Common Shares, the number of Common Shares offered, the offering price, and any other terms specific to the Common Shares being offered, (ii) in the case of Warrants, the offering price, the designation, the number and the terms of the Common Shares purchasable upon exercise of the Warrants, any procedures that will result in the adjustment of these numbers, the exercise price, the dates and periods of exercise and any other terms specific to the Warrants being offered, and (iii) in the case of Units, the number of Units offered, the offering price of the Units, the number, designation and terms of the Common Shares and Warrants comprising the Units and any procedures that will result in the adjustment of those numbers and any other specific terms applicable to the offering of Units. Where required by statute, regulation or policy, and where Securities are offered in currencies other than United States dollars, appropriate disclosure of foreign exchange rates applicable to the Securities will be included in the Prospectus Supplement describing the Securities.

All shelf information permitted under applicable law to be omitted from this Prospectus will be contained in one or more Prospectus Supplements that will be delivered to purchasers together with this Prospectus. Each Prospectus Supplement will be incorporated by reference into this Prospectus for the purposes of securities legislation as of the date of the Prospectus Supplement and only for the purposes of the distribution of the Securities to which the Prospectus Supplement pertains.

This Prospectus constitutes a public offering of the Securities only in those jurisdictions where they may be lawfully offered for sale and only by persons permitted to sell the Securities in those jurisdictions. We may offer and sell Securities to, or through, underwriters or dealers and also may offer and sell certain Securities directly to other purchasers or through agents pursuant to exemptions from registration or qualification under applicable securities laws. A Prospectus Supplement relating to each issue of Securities offered thereby will set forth the names of any underwriters, dealers, or agents involved in the offering and sale of the Securities and will set forth the terms of the offering of the Securities, the method of distribution of the Securities including, to the extent applicable, the proceeds we will receive and any fees, discounts or any other compensation payable to underwriters, dealers or agents and any other material terms of the plan of distribution.

- iii -

Our Common Shares are currently traded under the symbol “LGO” on the Toronto Stock Exchange (the “TSX”) and on the Nasdaq Capital Market (“Nasdaq”). On September 9, 2025 (the last trading day prior to the date of this Prospectus), the closing price of the Common Shares on: (i) the TSX was C$2.06; and (ii) the Nasdaq was $1.50. We will apply to have any Common Shares distributed under this Prospectus listed on the TSX and the Nasdaq provided the Common Shares are currently listed or traded on such exchanges. Any listing and admission will be subject to Largo fulfilling all of the listing requirements of the TSX and the Nasdaq, respectively. Unless otherwise specified in the applicable Prospectus Supplement, any offering of Warrants or Units will be a new issue of Securities with no established trading market and, accordingly, such Securities will not be listed on any securities or stock exchange or on any automated dealer quotation system.

On September 9, 2025, the aggregate market value worldwide of our outstanding common equity held by non-affiliates was approximately $54,038,481, based on 36,025,654 Common Shares outstanding held by non-affiliates and a per share price of $1.50 based on the closing sale price of the Common Shares on Nasdaq on September 9, 2025. Pursuant to General Instruction I.B.5. of Form F-3, in no event will we sell our securities in a public primary offering with a value exceeding one-third of our public float in any 12-month period so long as our public float remains below $75,000,000. During the 12 calendar months prior to and including the date of this Prospectus, we have not offered or sold any securities pursuant to General Instruction I.B.5. of Form F-3.

We are an "emerging growth company" as defined by the Jumpstart Our Business Startups Act of 2012 (the "JOBS Act") and, as such, we have elected to comply with certain reduced public company reporting requirements for this Prospectus and future filings. However, we have elected not to take advantage of the extended transition period allowed for emerging growth companies for complying with new or revised accounting guidance as allowed by Section 107 of the JOBS Act and Section 7(a)(2)(B) of the Securities Act of 1933, as amended, (the "Securities Act").

There is no market through which the Warrants or Units may be sold and purchasers may not be able to resell such Securities purchased under this Prospectus and any applicable Prospectus Supplement. This may affect the pricing of such Securities in the secondary market, the transparency and availability of trading prices, the liquidity of the Securities, and the extent of issuer regulation. See "Risk Factors".

Our principal executive offices are located at 1 First Canadian Place, 100 King Street West, Suite 1600, Toronto, Ontario M5X 1G5, Telephone: (416) 861-9797.

We have prepared this Prospectus in accordance with United States disclosure requirements. Our financial statements are prepared in accordance with International Financial Reporting Standards as issued by the International Accounting Standards Board and thus may not be comparable to financial statements of United States companies.

Purchasers of the Securities should be aware that the acquisition of the Securities may have tax consequences in the United States and in Canada. Such consequences for purchasers who are resident in, or citizens of, the United States, or who are resident in Canada may not be described fully herein or in any applicable Prospectus Supplement. Purchasers of the Securities should read the tax discussion contained in the applicable Prospectus Supplement with respect to a particular offering of Securities.

The enforcement by investors of civil liabilities under United States federal securities laws may be affected adversely by the fact that Largo is incorporated and governed under the laws of Canada, that some of our officers and directors are residents of countries other than the United States, that some or all of the underwriters, if any, may be residents of a foreign country, and a substantial portion of our assets and some of said persons are located outside the United States.

- iv -

No underwriter has been involved in the preparation of this Prospectus nor has any underwriter performed any review of the contents of this Prospectus.

Investing in the Securities involves a high degree of risk. Prospective purchasers of the Securities should carefully consider all the information in this Prospectus and in the documents incorporated by reference in this Prospectus. See "Risk Factors" beginning on page 9 of this Prospectus.

Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of these securities or determined if this Prospectus is truthful or complete. Any representation to the contrary is a criminal offense.

Except as otherwise indicated, references in this Prospectus to "Largo," "Company," "we," "us" and "our" refer to Largo Inc. and its consolidated subsidiaries.

MARKET AND INDUSTRY DATA

Unless otherwise indicated, the market and industry data contained or incorporated by reference in this Prospectus is based upon information from independent industry publications, market research, analyst reports and surveys and other publicly available sources. Although we believe these sources to be generally reliable, market and industry data is subject to interpretation and cannot be verified with complete certainty due to limits on the availability and reliability of raw data, the voluntary nature of the data gathering process and other limitations and uncertainties inherent in any survey. We have not independently verified any of the data from third party sources referred to or incorporated by reference herein and accordingly, the accuracy and completeness of such data is not guaranteed.

Financial statements included or incorporated by reference herein have been prepared in accordance with International Financial Reporting Standards as issued by the International Accounting Standards Board ("IFRS") and are audited in accordance with the standards of the Public Company Accounting Oversight Board (United States), however, are also subject to Canadian auditing and auditor independence standards and thus may not be comparable to financial statements of United States companies.

The following tables set out the average annual exchange rates according to information published by the Bank of Canada and the resulting currency conversion if one United States dollar, one Brazilian real and one Euro were exchanged for the equivalent in Canadian dollars.

EMERGING GROWTH COMPANY

We are an “emerging growth company” as defined in Section 3(a) of the Exchange Act as amended by the JOBS Act, and we may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies. We will continue to qualify as an “emerging growth company” until the earliest to occur of: (a) the last day of the fiscal year during which we had total annual gross revenues of $1,235,000,000 (as such amount is indexed for inflation every 5 years by the SEC) or more; (b) the last day of our fiscal year following the fifth anniversary of the date of the first sale of equity securities pursuant to an effective registration statement under the Securities Act; (c) the date on which we have, during the previous 3-year period, issued more than $1,000,000,000 in non-convertible debt; or (d) the date on which we are deemed to be a “large accelerated filer”, as defined in Exchange Act Rule 12b-2.

Generally, a registrant that registers any class of its securities under Section 12 of the Exchange Act is required to include in the second and all subsequent annual reports filed by it under the Exchange Act a management report on internal control over financial reporting and, subject to an exemption available to registrants that are neither an "accelerated filer" or a "large accelerated filer" (as those terms are defined in Exchange Act Rule 12b-2), an auditor attestation report on management's assessment of internal control over financial reporting. However, for so long as we continue to qualify as an emerging growth company, we will be exempt from the requirement to include an auditor attestation report on management's assessment of internal controls over financial reporting in its annual reports filed under the Exchange Act, even if we were to qualify as an "accelerated filer" or a "large accelerated filer". In addition, Section 10(a)(3) of the Sarbanes-Oxley Act of 2002 has been amended by the JOBS Act to provide that, among other things, auditors of an emerging growth company are exempt from any rules of the Public Company Accounting Oversight Board requiring a supplement to the auditor's report in which the auditor would be required to provide additional information about the audit and the financial statements of the company.

CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

This Prospectus contains forward-looking statements concerning the Company's projects, capital, anticipated financial performance, business prospects and strategies and other general matters. These statements are subject to certain risks and uncertainties that could cause actual results to differ materially from those included in the forward-looking statement. The use of words such as "intend", "anticipate", "continue", "estimate", "expect", "may", "will", "project", "should", "believe" and similar expressions are intended to identify forward-looking statements. Any statements that express or involve discussions with respect to predictions, expectations, beliefs, plans, projections, objectives, assumptions or future events or performance are not statements of historical fact and may constitute forward-looking information. Statements relating to Mineral Resources are also forward-looking information, as they involve the implied assessment, based on certain estimates and assumptions that the Mineral Resources described can be profitably produced in the future. There is no certainty that it will be commercially viable to produce any portion of the Mineral Resources.

Forward-looking statements are necessarily based upon a number of estimates and assumptions related to the factors set forth below that, while considered reasonable by Largo in light of management's experience and perception of current conditions and expected developments, are inherently subject to significant business, economic and competitive uncertainties and contingencies.

Forward-looking information includes, without limitation, statements with respect to:

• the Company's sales operations and anticipated sales of vanadium products, ilmenite and TiO₂;

• the timing and amount of estimated future production and sales;

• costs of future activities and operations;

• the extent of capital and operating expenditures;

• eventual production from the Ilmenite Plant and/or the titanium project;

• the Company's ability to sell ilmenite, titanium dioxide pigment, V₂O₅ or other vanadium commodities on a profitable basis;

• the Company's ability to produce V₂O₅, FeV and V₂O₃ according to customer specifications;

• expectations regarding the continuity of mineral deposits;

• future prices of V₂O₅, V₂O₃, TiO₂, FeV, and ilmenite;

• future production at the Company's Maracás Menchen Mine;

• the extent and impact of global freight delays and higher inventory transit time;

• the realization of the anticipated benefits of previously announced transactions or other expectations after the completion of previously announced transactions;

• the competitiveness of the Company's investment in vanadium flow battery technology in the long duration energy storage systems market;

• the Company's ability to maintain, protect and develop its intellectual property and technology;

• the adoption of vanadium flow battery technology generally in the market;

• the cost of producing and implementing the vanadium flow battery technology;

• the impact of the ongoing conflict between Russia and Ukraine, including the potential for broader economic disruption;

• the results in the Company's Technical Report including resource estimates;

• expectations regarding any environmental issues that may affect planned or future exploration and development programs and the potential impact of complying with existing and proposed environmental laws and regulations;

• receipt and timing of third party approvals;

• government regulation of mineral exploration and development operations in Brazil;

• expectations regarding any social or local community issues in Brazil that may affect planned or future exploration and development programs; and

• statements in respect of V₂O₅, V₂O₃, TiO₂, ilmenite, and LDES systems demand and supply.

These statements and information are only predictions based on current information and knowledge, some of which may be attributed to third party industry sources. Actual future events or results may differ materially. Undue reliance should not be placed on such forward-looking information, as there can be no assurance that the plans, intentions or expectations upon which they are based will occur. By its nature, forward-looking information involves numerous assumptions, known and unknown risks and uncertainties, both general and specific, that contribute to the possibility that the predictions, forecasts, projections and other forward-looking information will not be realized.

The following are some of the assumptions upon which forward-looking information is based:

• that general business and economic conditions will not change in a material adverse manner;

• the continued and growing demand for LDES systems and the movement towards a low-carbon future;

• demand for, and improving price of, V₂O₅, V₂O₃, FeV, ilmenite, TiO₂ and other vanadium commodities;

• that the estimates of the Mineral Resources and Mineral Reserves at the Maracás Menchen Mine are within reasonable bounds of accuracy (including with respect to size, grade and recovery and the operational and price assumptions on which such estimates are based);

• that the Company will not experience any material accident, labour dispute or failure of plant or equipment or other material disruption in the Company's operations at the Maracás Menchen Mine;

• the availability of financing for operations and development;

• that the Company will enter into agreements for the sales of vanadium, ilmenite and TiO₂ products on favourable terms and for the sale of substantially all of its annual production capacity;

• the Company's ability to mitigate the impact of future rainfall;

• the benefit of Largo Physical Vanadium Corp. ("LPV") to Largo, the Storion Energy LLC ("Storion Energy") joint venture, and the vanadium market generally;

• receipt of regulatory and governmental approvals, permits and renewals in a timely manner;

• the Company's ability to procure equipment and operating supplies in sufficient quantities and on a timely basis;

• the competitiveness of the Company's investment in vanadium flow battery technology;

• that the Company's plans for iron ore, ilmenite, titanium dioxide pigment and vanadium flow batteries can be achieved;

• the potential impact of the ongoing conflict between Russia and Ukraine on the Company;

• the Company's ability to attract and retain skilled personnel and directors; and

• the ability of management to execute strategic goals.

Actual results could differ materially from those anticipated in this forward-looking information as a result of the risks and uncertainties including, without limitation:

• volatility in prices of, and demand for, V₂O₅, V₂O₃, FeV, ilmenite, TiO₂ and other vanadium commodities;

• uncertainties regarding our ability to continue as a going concern;

• uncertainties regarding the rate of inflation and its effect on the profitability of long-term contracts;

• unexpected operational events and delays;

• risks inherent in mineral exploration and development;

• uncertainties associated with estimating Mineral Resources and Mineral Reserves (including with respect to size, grade and recovery and the operational and price assumptions on which such estimates are based);

• uncertainties related to title to the Company's mineral projects;

• risks inherent with the introduction and reliance on recently developed vanadium flow battery technology;

• revocation of government approvals;

• risks associated with our material financing arrangements and our covenants thereunder, including our ability to meet such obligations as they come due;

• tightening of the credit markets, global economic uncertainty and counterparty risk;

• failure of plant, equipment or processes to operate as anticipated;

• competition for, among other things, capital and skilled personnel;

• geological, technical and drilling problems;

• fluctuations in foreign exchange or interest rates and stock market volatility;

• rising costs of labour and equipment;

• disruption caused by labour actions;

• risks associated with political and/or economic instability in Brazil;

• compliance with applicable sanctions regimes;

• inherent uncertainties involved in the legal dispute resolution process, including in foreign jurisdictions;

• changes in income tax and other laws of foreign jurisdictions; and

• other factors discussed under "Risk Factors" in this Prospectus and the Company's filings incorporated by reference herein.

Assumptions relating to the potential mineralisation of the Maracás Menchen Mine are discussed in the Company’s Technical Report which is available under the Company’s profile on System for Electronic Document Analysis and Retrieval + (“SEDAR+”) and available on www.sec.gov.

Additional risks and uncertainties not currently known to the Company, or that the Company currently deems to be immaterial, may also materially and adversely affect the Company's business and prospects. Should one or more of these risks and uncertainties materialize, or should any of the underlying assumptions prove incorrect, actual results may vary materially from those described in forward-looking information.

Although the Company has attempted to identify important factors that could cause actual actions, events or results to differ materially from those described in forward-looking information, there may be other factors that cause actions, events or results not to be as anticipated, estimated or intended. There can be no assurance that forward-looking information will prove to be accurate, as actual results and future events could differ materially from those anticipated in such information. The reader is cautioned not to place undue reliance on forward-looking information.

The forward-looking information is presented for the purpose of assisting investors in understanding the Company's plans, objectives and expectations in making an investment decision and may not be appropriate for other purposes. This forward-looking information is expressly qualified in its entirety by this cautionary statement. Forward-looking information contained in this Prospectus or documents incorporated herein by reference are made as of the date of this Prospectus or the document incorporated herein by reference, as applicable, and are accordingly subject to change after such date. The Company disclaims any obligation to update any such forward-looking information to reflect events or circumstances after the date of such information, or to reflect the occurrence of anticipated or unanticipated events, except as required by law.

If any such risks actually occur, the Company's business, financial condition and results of operations could be materially adversely affected.

In addition to the risks set out in the Company's latest Annual Information Form included as Exhibit 99.1 to the Company's Annual Report on Form 40-F for the year ended December 31, 2024, filed on March 28, 2025, and the other risk factors presented in a Prospectus Supplement or other reports that may, from time to time, be incorporated by reference into this Prospectus, prospective investors should also carefully consider the risks set out below.

There is uncertainty about our ability to continue as a "going concern."

There is substantial doubt about our ability to continue as a going concern. We have included disclosure in our annual audited financial statements describing material uncertainties related to our ability to continue as a going concern and the report of our independent registered public accounting firm incorporated by reference in this Prospectus contains an explanatory paragraph on our consolidated financial statements stating there is substantial doubt about our ability to continue as a going concern, meaning that we may not be able to continue in operation for the foreseeable future or be able to realize assets and discharge liabilities in the ordinary course of operations.  Such material uncertainties could materially limit our ability to raise additional funds through the issuance of new equity securities or otherwise.

We incurred a net loss of $50,565,000 for the year ended December 31, 2024 (year ended December 31, 2023 - $32,358,000) and had a working capital deficit (current assets less current liabilities) of $20,972,000 (December 31, 2023 - surplus of $94,668,000). We incurred a net loss of $14,957,000 for the six months ended June 30, 2025 (six months ended June 30, 2024 - $27,489,000) and had a working capital deficit (current assets less current liabilities) of $69,398,000 (December 31, 2024 - deficit of $20,972,000), which includes $81,323,000 in debt maturing within the next twelve months ($27,573,000 maturing by September 30, 2025 and an additional $50,000,000 maturing by December 31, 2025, resulting in a total of $77,573,000 maturing by December 31, 2025). In August 2025, we agreed to a 60-day extension to pay a $7,500,000 principal payment due on one of our outstanding debt facilities in the principal amount owed of $15,000,000.        

We have experienced declining operating results and cash flows over the course of the last 18 months as a result of declining vanadium prices and operational challenges. Since December 31, 2023, vanadium prices have declined by over 23%, which has had a significant impact on our cash flows. We have implemented changes to address underlying operating issues and announced an operational turnaround plan and additional cost optimization incentives at the Maracás Menchen Mine that we believe are required in order to generate positive cash flows from operating activities. In the three months ended June 30, 2025, we had positive cash provided by operating activities before working capital items of $2,151,000 an improvement from the cash used by operating activities before working capital items in the three months ended March 31, 2025 of $8,492,000. There can be no assurance that we will have sufficient liquidity to fund operating activities and repay debt in the short term until additional financing is received and the price received for our vanadium increases. There can be no assurance that vanadium prices will increase or the other initiatives will be successful.

If we are unable to improve our liquidity position, by, among other things, raising capital through public or private offerings or reducing our expenses, we may exhaust our cash resources and will be unable to continue our operations. If we cannot continue as a viable entity, our shareholders would likely lose most or all of their investment in us. There is no assurance that sufficient financing will be available when needed to allow us to continue as a going concern. The perception that we may not be able to continue as a going concern may also make it more difficult to raise additional funds or operate our business due to concerns about our ability to meet our contractual obligations. Any inability to raise additional funds, when needed, could materially adversely affect our business, financial condition and results of operations.

An investment in the Securities is speculative and you may lose your entire investment

An investment in the Securities is speculative and may result in the loss of an investor's entire investment. Only potential investors who are experienced in high-risk investments and who can afford to lose their entire investment should consider an investment in the Company.

You may experience future dilution as a result of future equity offerings.

In order to raise additional capital, we may in the future offer additional Common Shares or other securities convertible into or exchangeable for Common Shares at prices that may not be the same as the price per share paid by any investor in an offering in a subsequent Prospectus Supplement. We may sell Common Shares or other securities in any other offering at a price per share that is less than the price per share or other security paid by any investor in an offering in a subsequent Prospectus Supplement, and investors purchasing Common Shares or other securities in the future could have rights superior to you. The price per share at which we sell additional Common Shares or securities convertible or exchangeable into Common Shares, in future transactions may be higher or lower than the price per share paid by any investor in an offering under a subsequent Prospectus Supplement.

There can be no assurance as to the liquidity of the trading market for certain Securities or that a trading market for certain Securities will develop.

No assurance can be given that an active or liquid trading market for the Common Shares will be sustained. If an active or liquid market for the Common Shares fails to be sustained, the prices at which such Common Shares trade may be adversely affected. Whether or not the Common Shares will trade at lower prices depends on many factors, including the liquidity of the Common Shares, prevailing interest rates, the markets for similar securities, general economic conditions and the Company's financial condition, historic financial performance and future prospects.

There is no public market for our Warrants, and unless otherwise specified in the applicable Prospectus Supplement, the Company does not intend to apply for listing of Warrants. If these securities are traded after their initial issue, they may trade at a discount from their initial offering prices depending on the market for similar securities, prevailing interest rates and other factors, including general economic conditions and the Company's financial condition. There can be no assurance as to the liquidity of the trading market for any Warrants or that a trading market for these securities will develop.

The trading price for the Company's securities is volatile.

The trading price of the Common Shares has been and may continue to be subject to large fluctuations which may result in losses to investors. The trading price of the Common Shares may increase or decrease in response to a number of events and factors, including:

• changes in the market price of V₂O₅ or other by-product metals the Company sells;

• events affecting economic circumstances in Canada, Brazil and the United States and elsewhere;

• trends in the mining and energy storage industries and the markets in which the Company operates;

• changes in financial estimates and recommendations by securities analysts;

• acquisitions, investments, divestitures and financings;

• quarterly variations in operating results;

• compliance with new and existing regulations, including with respect to water and tailings management and greenhouse gas emissions;

• the actions of other companies in the mining industry;

• the sale of a large number of Common Shares; and

• the operating and share price performance of other companies that investors may deem comparable.

Wide price swings are currently common in the markets on which the Company's securities trade. This volatility may adversely affect the prices of the Common Shares regardless of the Company's operating performance.

In addition, the market price of the Common Shares and any other Securities offered hereunder that become listed and posted for trading on the TSX, Nasdaq or any other stock exchange may be affected by many variables not directly related to the Company's results and not within the Company's control, including developments that affect the market for all resource sector shares, the breadth of the public market for the Common Shares or any other Securities offered hereunder that become listed and posted for trading on the TSX, Nasdaq, or any other stock exchange, and the attractiveness of alternative investments. In addition, securities markets have recently experienced an extreme level of price and volume volatility, and the market price of securities of many companies has experienced wide fluctuations which have not necessarily been related to the operating performance, underlying asset values or prospects of such companies. As a result of these and other factors, the Company's share price may be volatile in the future and may decline below the price paid for Securities offered hereunder. Accordingly, investors may not be able to sell their Securities at or above the price paid for Securities offered hereunder.

The Company will have broad discretion in the use of the net proceeds of any offering of Securities.

Management of the Company will have broad discretion with respect to the application of net proceeds received from the sale of Securities from the capital of the Company under this Prospectus and a future Prospectus Supplement and may spend such proceeds in ways that do not improve the Company's results of operations or enhance the value of the Common Shares or its other Securities issued and outstanding from time to time. Any failure by management to apply these funds effectively could result in financial losses that could have a material adverse effect on the Company's business or cause the price or value of the Company's issued and outstanding securities to decline.

Changing political and geopolitical conditions, including changing international trade policies and the implementation of wide-ranging, reciprocal and retaliatory tariffs, surtaxes and other similar import or export duties, or trade restrictions, could adversely impact our business, prospects, operations and financial performance.

Changes in political and geopolitical conditions may be difficult to predict and may adversely affect our business, prospects, operations and financial performance. For example, changes in political and geopolitical conditions may lead to changes in governmental policies, laws and regulations, including with respect to sanctions, taxes, tariffs, surtaxes and other similar import or export duties, import and export controls or restrictions, tariff rate quotas, and the general movement of goods, materials, services and capital, or may lead to uncertainty as to the potential for such changes. In particular, on July 30, 2025, Executive Order 14323 was issued by United States President Donald Trump, increasing tariffs on imports from Brazil from 10% to 50%, effective August 6, 2025. As a result, the Company is evaluating the potential commercial impact on its vanadium product sales to U.S. customers, including high-purity and ferrovanadium products. Commercial adjustments, including a reassessment of the Company's U.S. customer strategy, may be necessary if the current tariff regime remains in place.  There can be no assurance that any such efforts will be effective in mitigating the impacts of the tariffs on our business, prospects, operations and financial condition, which may be significantly impacted should the current tariff remain in place indefinitely.

The shifts in trade policies in the U.S. and other countries are rapidly evolving and difficult to predict. The ultimate impact of any announced or future tariffs, surtaxes, or other similar import or export duties, and trade restrictions will depend on various factors, including what is ultimately implemented, the timing of implementation and the amount, scope and nature of such measures and potential exclusions from the application of those measures. The potential implications of such uncertainty, which include trade barriers, exchange rate fluctuations, rising costs for miners and other hardware and equipment and broader market contractions, could adversely affect our business, prospects, operations and financial performance.

If we are characterized as a passive foreign investment company, U.S. holders may be subject to adverse U.S. federal income tax consequences.

U.S. investors should be aware that they could be subject to certain adverse U.S. federal income tax consequences in the event that the Company is classified as a "passive foreign investment company" ("PFIC") for U.S. federal income tax purposes. The determination of whether the Company is a PFIC for a taxable year depends, in part, on the application of complex U.S. federal income tax rules, which are subject to differing interpretations, and the determination will depend on the composition of the Company's income, expenses and assets from time to time and the nature of the activities performed by the Company's officers and employees. Based on the composition of the Company's income and the value of its assets as reported for financial statement purposes, the Company does not believe that it is classified as a PFIC for its taxable year ending December 31, 2024. However, the Company has not engaged such an analysis applying U.S. federal income tax rules, which may vary from financial accounting rules. Although the Company does not expect to be a PFIC for the current year, the determination as to whether the Company is a PFIC for any given year depends on the composition of the Company's income, expenses and assets for the entire year and, therefore, the Company cannot definitively ascertain whether it will be classified as a PFIC for the current taxable year. Prospective investors should carefully read the discussion under the heading "Certain U.S. Federal Income Tax Considerations for U.S. Holders" for more information and consult their own tax advisors regarding the likelihood and consequences of the Company being treated as a PFIC for U.S. federal income tax purposes, including the advisability of making certain elections that may mitigate certain possible adverse U.S. federal income tax consequences that may result in an inclusion in gross income without receipt of such income.

OUR COMPANY

General

Largo is a globally recognized supplier of high-quality vanadium and ilmenite products, sourced from its world-class Maracás Menchen Mine in Brazil. As one of the world's largest primary vanadium producers, Largo produces critical materials that empower global industries, including steel, aerospace, defense, chemical, and energy storage sectors. The Company is committed to operational excellence and sustainability, leveraging its vertical integration to ensure reliable supply and quality for its customers.

Largo is also strategically invested in the energy storage sector through its 50% ownership of Storion Energy, a joint venture with Stryten Energy LLC focused on scalable domestic electrolyte production and battery stack manufacturing for utility-scale vanadium flow battery long-duration energy storage solutions in the U.S.

The Maracás Menchen Project is the Company's sole material project for the purposes of NI 43-101. The Maracás Menchen Project consists of the currently operating Maracás Menchen Mine (Campbell Pit) and includes a number of other deposits being explored throughout the project area. The Maracás Menchen Mine is our principal operating asset and has accounted for substantially all of our revenues since commencing operations in 2014. The Company is incorporated and exists under the Business Corporations Act (Ontario) ("OBCA") and its Common Shares are listed on the TSX under the symbol "LGO" and on the NASDAQ under the symbol "LGO".

The current Technical Report, effective as of January 30, 2024, describes the Maracás Menchen Mine (Campbell Pit) as a large-scale vanadium and titanium project with Proven Mineral Reserves of 48.67 million tonnes at an average grade of 0.64% V₂O₅ and 7.46% TiO₂ and with Probable Mineral Reserves of 52.36 million tonnes with an average grade of 0.50% V₂O₅ and 7.52% TiO₂. The Maracás Menchen Mine currently produces V₂O₅ equivalent and ilmenite products from the Campbell Pit and effective as of January 30, 2024 had an estimated mine life of 31 years. Based on the current mine plan and the successful development of the NAN, SJO, NAO, and GAN deposits, mining is planned to begin in 2032 at the conclusion of mining at the Campbell Pit. The Technical Report outlines a robust supply of vanadium, ilmenite and titanium through various proposed operational scenarios over the project life, including total LOM V₂O₅ equivalent production of 346.6 kt, ilmenite concentrate production of 7,766.6 kt and TiO2 pigment production opportunity of 2,499 kt.

Largo is currently one of the lowest cost primary producers of V₂O₅ in the world due to the characteristics of the Maracás Menchen Mine's ore body and our operating efficiency. Largo is solely responsible for the global sales, distribution and marketing of its vanadium products through its established team of sales professionals. See "General Development of the Business - Three Year History - Operations", and "Description of the Business - Marketing and Distribution".

The Company also has a portfolio of secondary projects consisting of (i) the Campo Alegre de Lourdes project, vanadiferous titano-magnetite property in Bahia, Brazil, (ii) the Northern Dancer Project, a tungsten and molybdenum property in Yukon, Canada and (iii) Currais Novos, a tungsten project in Rio Grande do Norte, Brazil. As of the date of this Prospectus, none of these projects are operational and the Company does not consider any of these projects to be material properties.

Energy Storage Investment

The Company's investment in energy storage exists through its wholly-owned subsidiary, Largo Clean Energy Corp. ("LCE"), based in Wilmington, Massachusetts and its involvement in the Storion JV (as defined below). In August 2023, we announced that LCE was exploring and evaluating potential strategic alternatives in the power generation markets globally. On December 19, 2024, the Company announced the signing of definitive agreements between LCE and Stryten Critical E Storage, LLC, an affiliate of Stryten Energy LLC, to establish a joint venture in Storion Energy, which intends to become a leading manufacturer of domestically produced vanadium electrolyte and remove other barriers to entry in the flow battery manufacturing industry (the "Storion Transaction"). Following the closing of the Storion Transaction in January of 2025, LCE owns 50% of Storion Energy and participates in the LDES sector through its investment in Storion Energy LLC (the "Storion JV").

Vanadium flow batteries can be preferred for use over non-vanadium-based LDES applications in densely populated and risk sensitive areas as the electrolyte solution used in these systems is non-volatile, as it is neither flammable nor explosive as a result of its high-water content. Vanadium flow batteries also have a comparatively long- life cycle due to the non-degrading properties of vanadium. The applications of the vanadium flow battery include, but are not limited to:

- Renewable Integration: Enabling the shift of renewable generated electricity to align with consumer demand by storing and delivering clean energy to consumers or businesses when the renewables are otherwise not producing power.

- Utilities/Grid Optimization: Storing energy when electricity lines, substations, and other equipment have excess bandwidth and then discharge to handle power quality and ancillary services, which allows for delaying or avoiding upgrades of T&D assets.

- Microgrids: Providing microgrids and island energy systems with a reliable source of clean energy, potentially enabling a full transition away from conventional generation with fossil fuels. Vanadium flow batteries also provide a source of power for microgrids when access to neighboring grids is unavailable.

- Commercial and Industrial Energy Independence: Enabling a transition away from conventional fossil fuels utilizing long-duration renewable energy storage integration. Vanadium flow batteries can serve as excellent surrogates for balancing and reserves of PV and wind integration for commercial and industrial applications.

- EV Charging Integration: Reducing grid demands through ultra-fast 350kW charging. The inherent non-flammability of vanadium flow batteries allows for installation near occupied structures like vehicle service stations, office parks, or parking garages.

Marketing and Distribution

Vanadium Sales

The Company is responsible for the marketing and distribution of all vanadium production including VPURE^® Flake and Powder, VPURE+^® Flake and Powder. Global supply of vanadium is relatively concentrated and is not readily sold on global marketplaces. Benchmark prices are generally based on the Fastmarkets Metal Bulletin or the CRU Indices. However, due to the supply and demand characteristics of vanadium, pricing is often difficult to ascertain and is subject to wide fluctuations, see "Risk Factors - Risks Related to the Business and Operations - Our business is highly dependent upon the price of V₂O₅ and FeV and our ability to produce V₂O₅ and FeV at the required customer specifications" in the Company's latest Annual Information Form included as Exhibit 99.1 to the Company's Annual Report on Form 40-F for the year ended December 31, 2024, filed on March 28, 2025. Global demand for vanadium is not as robust as compared to other minerals and so the marketing of vanadium products and the identification of key consumers and markets is critical to the distribution and sale of vanadium.

During 2024, the price of V₂O₅ in Europe ranged from $6.53 to $5.37 per pound and, as at, June 30, 2025, the average price posted by Fastmarkets Metal Bulletin was $5.05 per pound.

Ilmenite Sales

Ilmenite pricing is very dependent on its quality and recognition in the market. Publications such as FerroAlloysNet offer more than 15 prices for this commodity in China according to TiO₂ content and origin. During its ramp-up phase, Largo production and commercial teams are working closely with end-users to maximize the value of its production.

In January 2024, the Company delivered its first commercial sale of ilmenite. The transaction was based on FOB Brazil terms and shipped in containers. Going forward, the Company expects to optimize its logistics operations and costs with break-bulk shipments as well as local deliveries.

Our commercial team, operating under Largo Ireland, Largo USA and LVMSA, have successfully built out the Company's global sales capacity for all vanadium products having sold 9,600 tonnes (inclusive of 416 tonnes of purchased material) of V₂O₅ equivalent in 2024. Mr. Francesco D'Allesio, Chief Commercial Officer of Largo, is tasked with leading and implementing the Company's global sales and trading strategy. Mr. Randy Doyle, Director of Sales, Americas, is based in the USA and is tasked with supporting this global effort, with a focus on the American market.

The vanadium sales cycle commences in the fourth quarter of the year coincident with the main industry conferences in Europe and the United States. The Company intends to commit the majority of its anticipated annual vanadium production to annual sales contracts with remaining vanadium production being committed to spot sales.

Vanadium Flow Batteries

Demand for LDES is fast-growing as governments and large organizations push for net zero goals. While there are currently approximately 800 MWh across almost 200 vanadium flow batteries installed globally, according to Vanitec, LDES has the potential to be scaled up to 85-140 TWh by 2040 if 10% of all electricity generated would need to be stored in long duration energy at some point. (McKinsey & Company, 2021). Vanadium flow batteries have emerged as a viable long duration (> 4 hour) renewable energy storage system and are considered a cost competitive alternative to lithium-ion technology with their safe and continuous energy storage over a 20+ year life cycle with zero degradation.

Principal markets of Storion Energy's offerings are expected to be North America and Europe in the near to medium term. LDES systems are being solicited by utility companies and developers in both regions as they seek to incorporate higher percentages of renewable energy assets onto the electricity transmission systems. Commercial and industrial customers seeking to improve resiliency, power quality, and flexibility have also begun to look to vanadium flow battery solutions that have long asset life and non-volatile energy components. Microgrids continue to seek LDES as they strive to achieve 100% renewable energy targets and cope with the intermittency inherent in the power production asset class.

Recent Developments

On February 18, 2025, the Company appointed Gordon Babcock and Luis Alberto Rendon to Co-Chief Operating Officers of the Company, following the departure of Celio Pereira.

In June 2025, Storion Energy, signed a strategic supply agreement with TerraFlow Energy Operating LLC ("TerraFlow") to advance the adoption of vanadium flow batteries in the United States.

In Q2 2025, the Company signed a non-recourse factoring facility agreement for advances up to a limit of $10.0 million, with potential expansion to $30.0 million subject to customer and credit approvals. Under the terms of the agreement, the Company sells eligible accounts receivable to a third-party financial institution for advances equal to 85%, to a total limit of $10.0 million. The remaining 15% is received based on customer payment terms.

On June 9, 2025, the Company received a default notice from a counterparty for failure to deliver 900 tonnes of V₂O₅ at the scheduled time. The same counterparty has also alleged that some of the V₂O₅ delivered previously has failed to meet the agreed upon specifications. The Company is currently reviewing the notice and assessing its available options.

In July 2025, Storion Energy secured a vanadium electrolyte lease for TerraFlow's 48 MWh Bellville flow battery project in Texas, which, when completed, will be one of the largest flow battery installations in the state. The lease is expected to commence in early 2027, when the electrolyte is deployed.

On July 30, 2025, Executive Order 14323 was issued by the United States President Donald Trump, increasing tariffs on imports from Brazil from 10% to 50%, effective August 6, 2025. As a result, the Company is evaluating the potential commercial impact on its vanadium product sales to U.S. customers, including high-purity and ferrovanadium products. Commercial adjustments, including a reassessment of the Company's U.S. customer strategy, may be necessary if the current tariff regime remains in place.

In July 2025, the Company increased the existing factoring facility limit from $10.0 million to $14.4 million.

In August 2025, the Company secured a loan facility for a principal amount of $6.0 million (the "Facility"). The Facility is secured against the Company's equity interest in LPV, in which the Company holds a 65.7% majority stake. The Facility has a term of six months, bears interest at an annualized rate of 15%, and includes a 1% arrangement fee.

CORPORATE GOVERNANCE

Material differences between Ontario Corporate Law and Delaware General Corporation Law

Our corporate affairs are governed by our articles and bylaws and the provisions of the OBCA. The OBCA differs from the various state laws applicable to U.S. corporations and their stockholders. The following is a summary of the material differences between the OBCA and the General Corporation Law of the State of Delaware ("DGCL").

This summary is qualified in its entirety by reference to the DGCL, the OBCA and our governing corporate instruments.

Other Important Provisions in Articles and Bylaws

The following is a summary of certain important provisions of our articles and bylaws, as amended. Please note that this is only a summary, is not intended to be exhaustive and is qualified in its entirety by reference to the articles and bylaws. For further information, please refer to the full version of the articles and bylaws, copies of which are filed as exhibits to the registration statement of which this prospectus forms a part.

Objects and Purposes

Our articles do not contain and are not required to contain a description of our objects and purposes. There is no restriction contained in our articles on the business that we may carry on.

Directors

Interested Transactions

The OBCA states that a director must disclose to us, in accordance with the provisions of the OBCA, the nature and extent of an interest that the director has in a material contract or material transaction, whether made or proposed, with us, if the director is a party to the contract or transaction, is a director or an officer or an individual acting in a similar capacity of a party to the contract or transaction, or has a material interest in a party to the contract or transaction.

A director who holds an interest in respect of any material contract or transaction into which we have entered or propose to enter is not entitled to vote on any directors' resolution to approve that contract or transaction, unless the contract or transaction:

Remuneration of Directors

The OBCA provides that the remuneration of directors, if any, may be determined by the directors subject to our articles and bylaws. That remuneration may be in addition to any salary or other remuneration paid to any employees who are also directors.

Age Limit Requirement

Neither our articles nor the OBCA impose any mandatory age-related retirement or non-retirement requirement for directors.

Action Necessary to Change the Rights of Holders of Shares

Shareholders can authorize the amendment of our articles to create or vary the special rights or restrictions attached to any of the shares by passing a special resolution. However, a right or special right attached to any class or series of shares may not be prejudiced or interfered with unless the shareholders holding shares of that class or series to which the right or special right is attached consent by a separate special resolution. A special resolution means a resolution passed by: (1) a majority of not less than two-thirds of the votes cast by the applicable class or series of shareholders who vote in person or by proxy at a meeting or (2) a resolution consented to in writing by all of the shareholders entitled to vote.

Shareholder Meetings

We must hold an annual general meeting of shareholders at least once every year at a time and place determined by the board of directors, provided that the meeting must not be held later than 15 months after the preceding annual general meeting but no later than six months after the end of the preceding financial year. A meeting of shareholders may be held on the date and at the time and place in or outside Ontario as the person(s) calling the meeting determine.

Directors may, at any time, call a special meeting of shareholders. Shareholders holding not less than 5% of the issued voting shares may also cause directors to call a shareholders' meeting.

A notice to convene a meeting, specifying the date, time and location of the meeting, and, where a meeting is to consider special business, the general nature of the special business, must be sent to shareholders, to each director and the auditor not less than 21 days prior to the meeting, although, as a result of applicable securities laws, the time for notice is effectively longer. Under the OBCA, shareholders entitled to notice of a meeting may waive or reduce the period of notice for that meeting, provided applicable securities laws requirements are met. The accidental omission to send notice of any meeting of shareholders to, or the non-receipt of any notice by, any person entitled to notice does not invalidate any proceedings at that meeting.

A quorum for meetings is two persons present and holding, or represented by proxy, 33-1/3% of the issued shares entitled to be voted at the meeting. If a quorum is not present at the opening of the meeting, the shareholders may adjourn the meeting to a fixed time and place but may not transact any further business.

Holders of outstanding common shares are entitled to attend meetings of shareholders. Except as otherwise provided with respect to any particular series of preferred shares, and except as otherwise required by law, the holders of preferred shares are not entitled as a class to receive notice of, or to attend or vote at any meetings of shareholders. Directors, the secretary (if any), the auditor and any other persons invited by the chairman or directors or with the consent of those at the meeting are entitled to attend at any meeting of shareholders but will not be counted in the quorum or be entitled to vote at the meeting unless he or she is a shareholder or proxyholder entitled to vote at the meeting.

Director Nominations

Pursuant to a bylaw relating to the advance notice of nominations of directors, shareholders seeking to nominate candidates for election as directors other than pursuant to a proposal or requisition of shareholders made in accordance with the provisions of the OBCA, must provide timely written notice to the corporate secretary. To be timely, a shareholder's notice must be received (i) in the case of an annual meeting of shareholders, not less than 60 days prior to the date of the annual meeting of shareholders; provided, however, that in the event that the annual meeting of shareholders is to be held on a date that is less than 50 days after the date on which the first public announcement of the date of the annual meeting was made, notice by the shareholder must be received not later than the close of business on the 10th day following the date of such public announcement; and (ii) in the case of a special meeting (which is not also an annual meeting) of shareholders called for any purpose which includes the election of directors to the board of directors, not later than the close of business on the 15th day following the day on which the first public announcement of the date of the special meeting was made. This bylaw also prescribes the proper written form for a shareholder's notice.

Impediments to Change of Control

Our articles do not contain any change of control limitations with respect to a merger, acquisition or corporate restructuring that involves our company.

Compulsory Acquisition

The OBCA provides that if, within 120 days after the date of a take-over bid made to shareholders of a corporation, the bid is accepted by the holders of not less than 90% of the shares (other than the shares held by the offeror or an affiliate of the offeror) of any class of shares to which the bid relates, the offeror is entitled to acquire (on the same terms on which the offeror acquired shares under the take-over bid) the shares held by those holders of shares of that class who did not accept the take-over bid. If a shareholder who did not accept the take-over bid (a dissenting offeree) does not receive an offeror's notice, with respect to a compulsory acquisition (as described in the preceding sentence), that shareholder may require the offeror to acquire those shares on the same terms under which the offeror acquired (or will acquire) the shares owned by the shareholders who accepted the take-over bid.

Ownership and Exchange Controls

Competition Act

Limitations on the ability to acquire and hold common shares may be imposed by the Competition Act (Canada). This legislation establishes a pre-merger notification regime for certain types of merger transactions that exceed certain statutory shareholding and financial thresholds. Mergers that are subject to notification cannot be closed until the required materials are filed and the applicable statutory waiting period has expired or been waived by the Commissioner of Competition (the "Commissioner"). Further, the Competition Act (Canada) permits the Commissioner to review any acquisition of control over or of a significant interest in our company, whether or not it is subject to mandatory notification. This legislation grants the Commissioner jurisdiction, for up to one year for notifiable acquisitions and for up to three years for non-notifiable acquisitions, to challenge such acquisitions before the Canadian Competition Tribunal if it would, or would be likely to, substantially prevent or lessen competition in any market in Canada.

Investment Canada Act

The Investment Canada Act requires notification and, in certain cases, advance review and approval by the Government of Canada of an investment to establish a new Canadian business by a non-Canadian or of the acquisition by a non-Canadian of "control" of a "Canadian business", all as defined in the Investment Canada Act. Generally, the threshold for advance review and approval will be higher in monetary terms for an investor from a country that is a member of the World Trade Organization. The Investment Canada Act generally prohibits the implementation of such a reviewable transaction unless, after review, the relevant minister is satisfied that the investment is likely to be of net benefit to Canada.

The Investment Canada Act contains various rules to determine if there has been an acquisition of control. For example, for purposes of determining whether an investor has acquired control of a corporation by acquiring shares, the following general rules apply, subject to certain exceptions. The acquisition of a majority of the voting shares of a corporation is deemed to be acquisition of control of that corporation. The acquisition of less than a majority but one-third or more of the voting shares of a corporation is presumed to be an acquisition of control of that corporation unless it can be established that, on the acquisition, the corporation is not controlled in fact by the acquiror through the ownership of voting shares. The acquisition of less than one-third of the voting shares of a corporation is deemed not to be acquisition of control of that corporation.

In addition, under the Investment Canada Act, national security review on a discretionary basis may also be undertaken by the federal government in respect of a much broader range of investments by a non-Canadian to acquire, in whole or in part, or to establish an entity carrying on all or any part of its operations in Canada, with the relevant test being whether such an investment by a non-Canadian could be "injurious to national security." The federal government typically subjects acquisitions of Canadian business that operate in the "critical mineral" supply chain to enhanced national security scrutiny (and vanadium is considered a "critical mineral"), especially where the potential purchaser is a state-owned enterprise. The Minister of Industry also has broad discretion to determine whether an investor is a non-Canadian and therefore may be subject to national security review. Review on national security grounds is at the discretion of the federal government and may occur on a pre- or post-closing basis.

Any of these provisions may discourage a potential acquirer from proposing or completing a transaction that may have otherwise presented a premium to our shareholders. We cannot predict whether investors will find us and our common shares less attractive because we are governed by foreign laws.

Restrictions on Capital

There is no law, governmental decree or regulation in Canada that restricts the export or import of capital or which would affect the remittance of dividends or other payments by us to non-Canadian holders of our Common Shares or preferred shares, other than withholding tax requirements.

Neither our articles nor our bylaws contain any change of control limitations with respect to a merger, acquisition or corporate restructuring that involves us.

This summary above is not a comprehensive description of relevant or applicable considerations regarding such requirements and, accordingly, is not intended to be, and should not be interpreted as, legal advice to any prospective purchaser and no representation with respect to such requirements to any prospective purchaser is made. Prospective investors should consult their own Canadian legal advisors with respect to any questions regarding the foregoing and securities law in the provinces and territories of Canada.

USE OF PROCEEDS

The net proceeds to be derived from the sale of Securities will be the issue price thereof less any commission paid in connection therewith and the expenses relating to the particular offering of Securities. The net proceeds to us from any offering of Securities, the proposed use of those proceeds and the specific business objectives that we wish to accomplish with such proceeds will be set out in the applicable Prospectus Supplement. There may be circumstances where, on the basis of results obtained or for other sound business reasons, a re-allocation of funds may be necessary or prudent. Accordingly, our management will have broad discretion in the application of the proceeds of an offering of Securities. The actual amount that we spend in connection with each intended use of proceeds may vary from the amounts specified in the applicable Prospectus Supplement and will depend on a number of factors, including those referred to under "Risk Factors" and any other factors set out in the applicable Prospectus Supplement. We may invest funds which we do not immediately use. Such investments may include short-term marketable investment grade securities.

We may, from time to time, issue securities (including debt securities) other than pursuant to this Prospectus.

PLAN OF DISTRIBUTION

We may sell the Securities, separately or together, to or through underwriters or dealers purchasing as principals for public offering and sale by them, and also may sell Securities to one or more other purchasers directly or through agents. Each Prospectus Supplement will set forth the terms of the offering, including the name or names of any underwriters or agents, if any, the purchase price or prices of the Securities and the proceeds we will receive from the sale of the Securities.

The Securities may be sold from time to time in one or more transactions at a fixed price or prices which may be changed or at market prices prevailing at the time of sale, at prices related to such prevailing market prices or at negotiated prices including sales in transactions that are deemed to be "at-the-market" distributions or "at the market offerings" as defined in Rule 415(a)(4) under the Securities Act, including sales made directly on the TSXV, Nasdaq or other existing trading markets for the securities. The prices at which the Securities may be offered may vary as between purchasers and during the period of distribution. If, in connection with the offering of Securities at a fixed price or prices, the underwriters, if any, have made a bona fide effort to sell all of the Securities at the initial offering price fixed in the applicable Prospectus Supplement, the public offering price may be decreased and thereafter further changed, from time to time, to an amount not greater than the initial public offering price fixed in such Prospectus Supplement, in which case the compensation realized by the underwriters will be decreased by the amount that the aggregate price paid by purchasers for the Securities is less than the gross proceeds paid to us by the underwriters.

Underwriters, dealers and agents who participate in the distribution of the Securities may be entitled under agreements to be entered into with us to indemnification by us against certain liabilities, including liabilities under the Securities Act and Canadian 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 and agents may be customers of, engage in transactions with, or perform services for, us in the ordinary course of business.

In connection with any offering of Securities, except as otherwise set out in a Prospectus Supplement relating to a particular offering of Securities, the underwriters may over-allot or effect transactions intended to maintain or stabilize the market price of the Securities offered at a level above that which might otherwise prevail in the open market. Such transactions, if commenced, may be discontinued at any time.

CERTAIN CANADIAN FEDERAL INCOME TAX CONSIDERATIONS

The following is, as of the date hereof, a summary of the principal Canadian federal income tax considerations generally applicable to a person who acquires Common Shares as beneficial owner and who, for the purposes of the Income Tax Act (Canada) (the "Tax Act"), and at all relevant times: (i) is not, and is not deemed to be, resident in Canada; (ii) does not use or hold and is not and will not be deemed to use or hold the Common Shares in connection with carrying on a business in Canada; (iii) deals at arm's length with the Company; (iv) is not affiliated with the Company; and (v) acquires and holds the Common Shares as capital property (a "Holder"). This summary does not apply to a Holder that carries on, or is deemed to carry on, an insurance business in Canada and elsewhere or that is an "authorized foreign bank" (as defined in the Tax Act). Such Holders should consult their own tax advisors.

Common Shares will generally be considered to be capital property to a Holder unless the Holder holds or uses the Common Shares or is deemed to hold or use the Common Shares in the course of carrying on a business of trading or dealing in securities or has acquired them or is deemed to have acquired them in a transaction or transactions considered to be an adventure or concern in the nature of trade.

This summary is based upon: (i) the current provisions of the Tax Act and the regulations thereunder (the "Regulations") in force as of the date hereof; (ii) all specific proposals ("Proposed Amendments") to amend the Tax Act or the Regulations that have been publicly announced by, or on behalf of, the Minister of Finance (Canada) prior to the date hereof; and (iii) our understanding of the current published administrative policies and assessing practices of the Canada Revenue Agency ("CRA"). No assurance can be given that the Proposed Amendments will be enacted or otherwise implemented in their current form, if at all. If the Proposed Amendments are not enacted or otherwise implemented as presently proposed, the tax consequences may not be as described below in all cases. Other than the Proposed Amendments, this summary does not take into account or anticipate any changes in law, the CRA's administrative policies or assessing practices, whether by legislative, regulatory, administrative, governmental or judicial decision or action, nor does it take into account any provincial, territorial or foreign income tax legislation or considerations, which considerations may differ significantly from the Canadian federal income tax considerations discussed in this summary.

This summary is of a general nature only, is not exhaustive of all possible Canadian federal income tax considerations and is not intended to be, nor should it be construed to be, legal or tax advice to any particular Holder. Accordingly, Holders should consult their own tax advisors with respect to their particular circumstances.

Dividends

Dividends paid or credited or deemed under the Tax Act to be paid or credited by the Company to a Holder on the Common Shares will generally be subject to Canadian withholding tax at the rate of 25% on the gross amount of the dividend, unless such rate is reduced by the terms of an applicable income tax treaty or convention. Under the Canada-United States Tax Convention (1980), as amended (the "US Treaty"), the rate of withholding tax on dividends paid or credited to a Holder who is resident in the U.S. for purposes of the US Treaty, is the beneficial owner of the dividends, and is fully entitled to benefits under the US Treaty (a "U.S. Holder") is generally limited to 15% of the gross amount of the dividend. The rate of withholding tax is further reduced to 5% if the beneficial owner of such dividend is a U.S. Holder that is a company that owns, directly or indirectly, at least 10% of the voting stock of the Company. The Multilateral Convention to Implement Tax Treaty Related Measures to Prevent Base Erosion and Profit Shifting of which Canada is a signatory, affects many of Canada's bilateral tax treaties (but not the US Treaty), including the ability to claim benefits thereunder. Holders are urged to consult their own tax advisors to determine their entitlement to relief under an applicable income tax treaty or convention.

Dispositions of Common Shares

A Holder will not be subject to tax under the Tax Act in respect of any capital gain realized on a disposition or deemed disposition of a Common Share, nor will capital losses arising therefrom be recognized under the Tax Act, unless the Common Share is, or is deemed to be, "taxable Canadian property" of the Holder for the purposes of the Tax Act and the Holder is not entitled to relief under an applicable income tax treaty or convention between Canada and the country in which the Holder is resident.

Provided that the Common Shares are listed on a "designated stock exchange" for the purposes of the Tax Act (which currently includes the TSX), at the time of disposition, the Common Shares generally will not constitute taxable Canadian property of a Holder at that time, unless at any time during the 60 month period immediately preceding the disposition, (i) 25% or more of the issued shares of any class or series of the capital stock of the Company were owned by, or belonged to, any combination of (a) the Holder, (b) persons with whom the Holder did not deal at arm's length, and (c) partnerships in which the Holder or a person described in (b) holds a membership interest directly or indirectly through one or more partnerships; and (ii) at such time, more than 50% of the fair market value of such shares was derived, directly or indirectly, from any combination of real or immovable property situated in Canada, "Canadian resource property" (as defined in the Tax Act), "timber resource property" (as defined in the Tax Act), or options in respect of, interests in, or for civil law rights in such properties, whether or not such property exists. Notwithstanding the foregoing, a Common Share may also be deemed to be taxable Canadian property to a Holder for purposes of the Tax Act in certain other circumstances. Holders should consult their own tax advisors as to whether their Common Shares constitute "taxable Canadian property" in their own particular circumstances.

CERTAIN U.S. FEDERAL INCOME TAX CONSIDERATIONS FOR U.S. HOLDERS

The following is a general summary of certain U.S. federal income tax considerations applicable to a U.S. Holder (as defined below) arising from and relating to the acquisition, ownership and disposition of Common Shares, Units and Warrants acquired pursuant to this offering and exercise, disposition, and lapse of Warrants, and the acquisition, ownership, and disposition of the Common Shares ("Warrant Shares") received upon exercise of such Warrants. The term "securities" as used in this summary includes the Common Shares, Units , Warrants, and Warrant Shares, as applicable.

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 considerations that may apply to a U.S. Holder as a result of the acquisition of securities pursuant to this offering. In addition, this summary does not take into account the individual facts and circumstances of any particular U.S. Holder that may affect the U.S. federal income tax consequences to such U.S. Holder, including specific tax consequences to a U.S. Holder under an applicable tax treaty. 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 U.S. Holder. This summary does not address the U.S. federal net investment income, U.S. federal alternative minimum, U.S. federal estate and gift, U.S. state and local, and non-U.S. tax consequences to U.S. Holders of the acquisition, ownership, and disposition of the securities. In addition, except as specifically set forth below, this summary does not discuss applicable tax reporting requirements. Each U.S. Holder should consult its own tax advisor regarding the U.S. federal, U.S. federal net investment income, U.S. federal alternative minimum, U.S. federal estate and gift, U.S. state and local, and non-U.S. tax consequences relating to the acquisition, ownership and disposition of the securities.

No ruling from the IRS has been requested, or will be obtained, regarding the U.S. federal income tax consequences of the ownership or disposition of the 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 discussion set forth in this summary. In addition, because the authorities on which this summary is based are subject to various interpretations, the IRS and U.S. courts could disagree with one or more of the positions taken in this summary.

Scope of this Summary

Authorities

This summary is based on the Internal Revenue Code of 1986, as amended (the "Code"), Treasury Regulations (whether final, temporary, or proposed) promulgated under the Code, published rulings of the IRS, published administrative positions of the IRS and U.S. court decisions, that are in effect and available, as of the date of this document. 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 retroactively. This summary does not discuss the potential effects, whether adverse or beneficial, of any proposed legislation that, if enacted, could be applied on a retroactive or prospective basis.

U.S. Holders

For purposes of this summary, the term "U.S. Holder" means a beneficial owner of the securities acquired pursuant to this offering that is for U.S. federal income tax purposes:

• a citizen or individual resident of the United States;

• a corporation (or other entity treated as a corporation for U.S. federal income tax purposes) organized under the laws of the United States, 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 United States and the control of one or more U.S. persons for all substantial decisions or (2) has a valid election in effect under applicable Treasury Regulations to be treated as a U.S. person.

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

This summary does not address the U.S. federal income tax considerations applicable to U.S. Holders that are subject to special provisions under the Code, including U.S. Holders that: (a) are tax-exempt organizations, qualified retirement plans, individual retirement accounts, or other tax-deferred accounts; (b) are financial institutions, underwriters, insurance companies, real estate investment trusts, or regulated investment companies; (c) are brokers or dealers in securities or currencies or U.S. Holders that are traders in securities that elect to apply a mark-to-market accounting method; (d) have a "functional currency" other than the U.S. dollar; (e) own securities as part of a straddle, hedging transaction, conversion transaction, constructive sale, or other integrated transaction; (f) acquired the securities in connection with the exercise of employee stock options or otherwise as compensation for services; (g) hold the securities other than as a capital asset within the meaning of Section 1221 of the Code (generally, property held for investment purposes); (h) are partnerships and other pass-through entities (and investors in such partnerships and entities); (i) are subject to special tax accounting rules; (j) own, have owned or will own (directly, indirectly, or by attribution) 10% or more of the total combined voting power or value of our outstanding shares; (k) are U.S. expatriates or former long-term residents of the U.S.; or (l) are subject to taxing jurisdictions other than, or in addition to, the United States. U.S. Holders that are subject to special provisions under the Code, including U.S. Holders described immediately above, should consult their own tax advisors regarding the U.S. federal, U.S. federal net investment income, U.S. federal alternative minimum, U.S. federal estate and gift, U.S. state and local, and non-U.S. tax consequences relating to the acquisition, ownership and disposition of the securities.

If an entity or arrangement that is classified as a partnership for U.S. federal income tax purposes holds the securities, the U.S. federal income tax consequences to such entity or arrangement and the owners of such entity or arrangement generally will depend on the activities of such entity or arrangement and the status of such owners. This summary does not address the tax consequences to any such entity or arrangement or owner. Owners of entities or arrangements that are classified as partnerships for U.S. federal income tax purposes should consult their own tax advisor regarding the U.S. federal income tax consequences arising from and relating to the acquisition, ownership, and disposition of the securities.

U.S. Federal Income Tax Consequences of the Acquisition of a Unit

No statutory, administrative or judicial authority directly addresses the treatment of a Unit or instruments similar to a Unit for U.S. federal income tax purposes and, therefore, that treatment is not entirely clear. The purchase price for each Unit will be allocated between a Common Share and a Warrant in proportion to their relative fair market values at the time such securities are issued to the U.S. Holder. Each investor must make his or her own determination of such value based on all the relevant facts and circumstances. This allocation of the purchase price for each such Unit will establish a U.S. Holder's initial tax basis for U.S. federal income tax purposes in the Common Share and a Warrant that comprise each such type of Unit. Any disposition of a Unit should be treated for U.S. federal income tax purposes as a disposition of a Common Share and a Warrant and the amount realized on the disposition should be allocated between the Common Share and the Warrant based on their respective relative fair market values at the time of disposition (as determined by each such Unit holder based on all relevant facts and circumstances).

The foregoing treatment of the Unit and a holder's purchase price allocation are not binding on the IRS or the courts. Because there are no authorities that directly address instruments that are similar to the Units, no assurance can be given that the IRS or the courts will agree with the characterization described above or the discussion below.

Accordingly, each prospective investor is urged to consult its own tax advisors regarding the tax consequences of an investment in a Unit (including alternative characterizations of a Unit). The balance of this discussion assumes that the characterization of the Units described above is respected for U.S. federal income tax purposes.

Passive Foreign Investment Company Rules

If we are considered a "passive foreign investment company" within the meaning of Section 1297 of the Code (a "PFIC") at any time during a U.S. Holder's holding period, the following sections will generally describe the potentially adverse U.S. federal income tax consequences to U.S. Holders of the acquisition, ownership, and disposition of the securities.

In any year in which we are classified as a PFIC, a U.S. Holder will be required to file an annual report with the IRS containing such information as Treasury Regulations and/or other IRS guidance may require. In addition to penalties, a failure to satisfy such reporting requirements may result in an extension of the time period during which the IRS can assess a tax. U.S. Holders should consult their own tax advisors regarding the requirements of filing such information returns under these rules, including the requirement to file an IRS Form 8621.

We generally will be a PFIC for any tax year in which (a) 75% or more of our gross income for such tax year is passive income (the "PFIC income test") or (b) 50% or more of the value of our assets either produce passive income or are held for the production of passive income, based on the quarterly average of the fair market value of such assets (the "PFIC asset test"). "Gross income" generally includes sales revenues less the cost of goods sold, plus income from investments and from incidental or outside operations or sources, and "passive income" generally includes, for example, dividends, interest, certain rents and royalties, certain gains from the sale of stock and securities, and certain gains from commodities transactions. Active business gains arising from the sale of commodities generally are excluded from passive income if substantially all of a foreign corporation's commodities are stock in trade or inventory, depreciable property used in a trade or business, or supplies regularly used or consumed in the ordinary course of its trade or business, and certain other requirements are satisfied.

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

Under certain attribution rules, if we are a PFIC, U.S. Holders will be deemed to own their proportionate share of any of our subsidiaries which is also a PFIC (a "Subsidiary PFIC"), and will generally be subject to U.S. federal income tax under the "Default PFIC Rules Under Section 1291 of the Code" discussed below on their proportionate share of any (i) distribution on the shares of a Subsidiary PFIC and (ii) disposition or deemed disposition of shares of a Subsidiary PFIC, both as if such U.S. Holders directly held the shares of such Subsidiary PFIC. Accordingly, U.S. Holders should be aware that they could be subject to tax under the PFIC rules even if no distributions are received and no redemptions or other dispositions of the securities are made. In addition, U.S. Holders may be subject to U.S. federal income tax on any indirect gain realized on the stock of a Subsidiary PFIC on the sale or disposition of the securities.

In particular, and without limiting the foregoing, the Company does not believe that it was a PFIC for its most recent taxable year or that it will be for future taxable years. A separate determination must be made after the close of each taxable year as to whether we are a PFIC for that year, and as a result, our PFIC status may change from year to year. The total value of our assets for purposes of the asset test generally will be calculated using the market price of the Common Shares or Warrant Shares, which may fluctuate considerably. Fluctuations in the market price of the Common Shares or Warrant Shares may result in us being a PFIC for any taxable year. Because of the uncertainties involved in establishing our PFIC status, there can be no assurance regarding whether we currently are treated as a PFIC, or may be treated as a PFIC in the future. If we are classified as a PFIC in any year during which a U.S. Holder holds the securities, we generally will continue to be treated as a PFIC as to such U.S. Holder in all succeeding years, regardless of whether we continue to meet the PFIC income test or PFIC asset test discussed above.

Default PFIC Rules Under Section 1291 of the Code

If we are a PFIC, the U.S. federal income tax consequences to a U.S. Holder of the acquisition, ownership, and disposition of the securities will depend on whether such U.S. Holder makes a "qualified electing fund" or "QEF" election (a "QEF Election") or makes a mark-to-market election under Section 1296 of the Code (a "Mark-to-Market Election") with respect to the Common Shares, or the Warrant Shares. A U.S. Holder that does not make either a QEF Election or a Mark-to-Market Election (a "Non-Electing U.S. Holder") will be taxable as described below.

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

Under Section 1291 of the Code, any gain recognized on the sale or other taxable disposition of the securities of a PFIC (including an indirect disposition of shares of a Subsidiary PFIC), and any excess distribution received on such securities (or a distribution by a Subsidiary PFIC to its shareholder that is deemed to be received by a U.S. Holder) must be ratably allocated to each day in a Non-Electing U.S. Holder's holding period for the securities. The amount of any such gain or excess distribution allocated to the tax year of disposition or distribution of the excess distribution and to years before the entity became a PFIC, if any, would be taxed as ordinary income (and not eligible for certain preferential tax rates, as discussed below). The amounts allocated to any other tax year would be subject to U.S. federal income tax at the highest tax rate applicable to ordinary income in each such year, and an interest charge would be imposed on the tax liability for each such year, calculated as if such tax liability had been due in each such year. A Non-Electing U.S. Holder that is not a corporation must treat any such interest paid as "personal interest," which is not deductible.

If we are a PFIC for any tax year during which a Non-Electing U.S. Holder holds the securities, it will continue to be treated as a PFIC with respect to such Non-Electing U.S. Holder, regardless of whether it ceases to be a PFIC in one or more subsequent tax years. If we cease to be a PFIC, a Non-Electing U.S. Holder may terminate this deemed PFIC status with respect to the Common Shares, and Warrant Shares by electing to recognize gain (which will be taxed under the rules of Section 1291 of the Code as discussed above) as if such securities were sold on the last day of the last tax year for which we were a PFIC. No such election, however, may be made with respect to the Warrants.

Under proposed Treasury Regulations, if a U.S. Holder has an option, warrant, or other right to acquire stock of a PFIC (such as the Warrants), such option, warrant or right is considered to be PFIC stock subject to the default rules of Section 1291 of the Code. Under rules described below, the holding period for the Warrant Shares will begin on the date a U.S. Holder acquires the related Warrant. This will impact the availability of the QEF Election and Mark-to-Market Election with respect to the Warrant Shares. Thus, a U.S. Holder will have to account for the Warrant Shares and Common Shares under the PFIC rules and the applicable elections differently.

QEF Election

A U.S. Holder that makes a QEF Election for the first tax year in which its holding period of its Common Shares begins generally will not be subject to the rules of Section 1291 of the Code discussed above with respect to its Common Shares. However, a U.S. Holder that makes a QEF Election will be subject to U.S. federal income tax on such U.S. Holder's pro rata share of (a) our net capital gain, which will be taxed as long-term capital gain to such U.S. Holder, and (b) our ordinary earnings, which will be taxed as ordinary income to such U.S. Holder. Generally, "net capital gain" is the excess of (a) net long-term capital gain over (b) net short-term capital loss, and "ordinary earnings" are the excess of (a) "earnings and profits" over (b) net capital gain. A U.S. Holder that makes a QEF Election will be subject to U.S. federal income tax on such amounts for each tax year in which we are a PFIC, regardless of whether such amounts are actually distributed to such U.S. Holder by us. However, for any tax year in which we are a PFIC and have no net income or gain, U.S. Holders that have made a QEF Election would not have any income inclusions as a result of the QEF Election. If a U.S. Holder that made a QEF Election has an income inclusion, such a U.S. Holder may, subject to certain limitations, elect to defer payment of current U.S. federal income tax on such amounts, subject to an interest charge. If such U.S. Holder is not a corporation, any such interest paid will be treated as "personal interest," which is not deductible.

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

The procedure for making a QEF Election, and the U.S. federal income tax consequences of making a QEF Election, will depend on whether such QEF Election is timely. A QEF Election will be treated as "timely" for purposes of avoiding the default PFIC rules discussed above if such QEF Election is made for the first year in the U.S. Holder's holding period for the Common Shares in which we were a PFIC. A U.S. Holder may make a timely QEF Election by filing the appropriate QEF Election documents at the time such U.S. Holder files a U.S. federal income tax return for such year.

A QEF Election will apply to the tax year for which such QEF Election is made and to all subsequent tax years, unless such QEF Election is invalidated or terminated or the IRS consents to revocation of such QEF Election. If a U.S. Holder makes a QEF Election and, in a subsequent tax year, we cease to be a PFIC, the QEF Election will remain in effect (although it will not be applicable) during those tax years in which we are not a PFIC. Accordingly, if we become a PFIC in another subsequent tax year, the QEF Election will be effective, and the U.S. Holder will be subject to the QEF rules described above during any subsequent tax year in which we qualify as a PFIC.

As discussed above, under proposed Treasury Regulations, if a U.S. Holder has an option, warrant or other right to acquire stock of a PFIC (such as the Warrants), such option, warrant or right is considered to be PFIC stock subject to the default rules of Section 1291 of the Code. However, a U.S. Holder of an option, warrant or other right to acquire stock of a PFIC may not make a QEF Election that will apply to the option, warrant or other right to acquire PFIC stock. In addition, under proposed Treasury Regulations, if a U.S. Holder holds an option, warrant or other right to acquire stock of a PFIC, the holding period with respect to shares of stock of the PFIC acquired upon exercise of such option, warrant or other right will include the period that the option, warrant or other right was held.

Consequently, under the proposed Treasury Regulations, if a U.S. Holder of the Common Shares that are part of a Unit makes a QEF Election, such election generally will not be treated as a timely QEF Election with respect to Warrant Shares and the rules of Section 1291 of the Code discussed above will continue to apply with respect to such U.S. Holder's Warrant Shares. However, a U.S. Holder of Warrant Shares should be eligible to make a timely QEF Election if such U.S. Holder makes a "purging" or "deemed sale" election to recognize gain (which will be taxed under the rules of Section 1291 of the Code discussed above) as if such Warrant Shares were sold for fair market value. As a result of the "purging" or "deemed sale" election, the U.S. Holder will have a new basis and holding period in the Warrant Shares acquired upon the exercise of the Warrants for purposes of the PFIC rules. In addition, gain recognized on the sale or other taxable disposition (other than by exercise) of the Warrants by a U.S. Holder will be subject to the rules of Section 1291 of the Code discussed above. Each U.S. Holder should consult its own tax advisor regarding the application of the PFIC rules to the securities.

If we determine that we are a PFIC for this year or any future taxable year, we currently expect that we would provide the information necessary for U.S. Holders to make a QEF Election. U.S. Holders should consult with their own tax advisors regarding the potential application of the PFIC rules to the ownership and disposition of the securities, and the availability of certain U.S. tax elections under the PFIC rules.

A U.S. Holder makes a QEF Election by attaching a completed IRS Form 8621, including a PFIC Annual Information Statement, to a timely filed U.S. federal income tax return. However, if we do not provide the required information with regard to us or any of our Subsidiary PFICs, U.S. Holders will not be able to make a QEF Election for such entity and will continue to be subject to the rules of Section 1291 of the Code discussed above that apply to Non-Electing U.S. Holders with respect to the taxation of gains and excess distributions.

Mark-to-Market Election

A U.S. Holder may make a Mark-to-Market Election with respect to the Common Shares and Warrant Shares only if such shares are marketable stock. The Common Shares and Warrant Shares generally will be "marketable stock" if the Common Shares and Warrant Shares are regularly traded on (a) a national securities exchange that is registered with the SEC, (b) the national market system established pursuant to Section 11A of the Exchange Act or (c) a foreign securities exchange that is regulated or supervised by a governmental authority of the country in which the market is located, provided that (i) such foreign exchange has trading volume, listing, financial disclosure, and other requirements and the laws of the country in which such foreign exchange is located, together with the rules of such foreign exchange, ensure that such requirements are actually enforced and (ii) the rules of such foreign exchange ensure active trading of listed stocks. If such stock is traded on such a qualified exchange or other market, such stock generally will be considered "regularly traded" for any calendar year during which such stock is traded, other than in de minimis quantities, on at least 15 days during each calendar quarter. Provided that the Common Shares and Warrant Shares are "regularly traded" as described in the preceding sentence, such shares are expected to be marketable stock. There can be no assurance that the common shares will be "regularly traded" in subsequent calendar quarters. U.S. Holders should consult their own tax advisors regarding the marketable stock rules. A Mark-to-Market Election will likely not be available with respect to the Warrants. Accordingly, each U.S. Holder should consult its own tax advisor regarding the availability of a Mark-to-Market Election with respect to the Warrants. The balance of this discussion generally assumes that a Mark-to-Market Election may be made with respect Common Shares or Warrant Shares.

A U.S. Holder that makes a Mark-to-Market Election with respect to its Common Shares or Warrant Shares generally will not be subject to the rules of Section 1291 of the Code discussed above with respect to such Common Shares or Warrant Shares. However, if a U.S. Holder does not make a Mark-to-Market Election beginning in the first tax year of such U.S. Holder's holding period for the Common Shares or Warrant Shares and such U.S. Holder has not made a timely QEF Election, the rules of Section 1291 of the Code discussed above will apply to certain dispositions of, and distributions on, the Common Shares and Warrant Shares.

Any Mark-to-Market Election made by a U.S. Holder for the Common Shares will also apply to such U.S. Holder's Warrant Shares. As a result, if a Mark-to-Market Election has been made by a U.S. Holder with respect to its Common Shares, any Warrant Shares received will automatically be marked-to-market in the year of exercise. Because, under the proposed Treasury Regulations, a U.S. Holder's holding period for Warrant Shares includes the period during which such U.S. Holder held the Warrants, a U.S. Holder will be treated as making a Mark-to-Market Election with respect to its Warrant Shares after the beginning of such U.S. Holder's holding period for the Warrant Shares unless the Warrant Shares are acquired in the same tax year as the year in which the U.S. Holder acquired its securities. Consequently, the default rules under Section 1291 described above generally will apply to the mark-to-market gain realized in the tax year in which Warrant Shares are received. However, the general mark-to-market rules will apply to subsequent tax years.

A U.S. Holder that makes a Mark-to-Market Election will include in ordinary income, for each tax year in which we are a PFIC, an amount equal to the excess, if any, of (a) the fair market value of the Common Shares and any Warrant Shares as of the close of such tax year over (b) such U.S. Holder's tax basis in such securities. A U.S. Holder that makes a Mark-to-Market Election will be allowed a deduction in an amount equal to the excess, if any, of (i) such U.S. Holder's adjusted tax basis in the Common Shares and any Warrant Shares, over (ii) the fair market value of such securities (but only to the extent of the net amount of previously included income as a result of the Mark-to-Market Election for prior tax years).

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

A U.S. Holder makes a Mark-to-Market Election by attaching a completed IRS Form 8621 to a timely filed U.S. federal income tax return. A timely Mark-to-Market Election applies to the tax year in which such Mark-to-Market Election is made and to each subsequent tax year, unless the securities cease to be "marketable stock" or the IRS consents to revocation of such election. Each U.S. Holder should consult its own tax advisor regarding the availability of, and procedure for making, a Mark-to-Market Election.

Although a U.S. Holder may be eligible to make a Mark-to-Market Election with respect to the Common Shares and Warrant Shares, no such election may be made with respect to the stock of any Subsidiary PFIC that a U.S. Holder is treated as owning because such stock is not marketable. Hence, the Mark-to-Market Election will not be effective to eliminate the interest charge and other income inclusion rules described above with respect to deemed dispositions of Subsidiary PFIC stock or distributions from a Subsidiary PFIC to its shareholder.

Other PFIC Rules

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

If finalized in their current form, the proposed Treasury Regulations applicable to PFICs would be effective for transactions occurring on or after April 1, 1992. Because the proposed Treasury Regulations have not yet been adopted in final form, they are not currently effective, and there is no assurance that they will be adopted in the form and with the effective date proposed. Nevertheless, the IRS has announced that, in the absence of final Treasury Regulations, taxpayers may apply reasonable interpretations of the Code provisions applicable to PFICs and that it considers the rules set forth in the proposed Treasury Regulations to be reasonable interpretations of those Code provisions. The PFIC rules are complex, and the implementation of certain aspects of the PFIC rules requires the issuance of Treasury Regulations which in many instances have not been promulgated and which, when promulgated, may have retroactive effect. U.S. Holders should consult their own tax advisors about the potential applicability of the proposed Treasury Regulations.

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

In addition, a U.S. Holder who acquires securities from a decedent will not receive a "step up" in tax basis of such securities to fair market value.

Special rules also apply to the amount of foreign tax credit that a U.S. Holder may claim on a distribution from a PFIC. Subject to such special rules, foreign taxes paid with respect to any distribution in respect of stock in a PFIC are generally eligible for the foreign tax credit. The rules relating to distributions by a PFIC and their eligibility for the foreign tax credit are complicated, and a U.S. Holder should consult with their own tax advisor regarding the availability of the foreign tax credit with respect to distributions by a PFIC.

The PFIC rules are complex, and each U.S. Holder should consult its own tax advisor regarding the PFIC rules (including the applicability and advisability of a QEF Election and Mark-to-Market Election) and how the PFIC rules may affect the U.S. federal income tax consequences of the acquisition, ownership, and disposition of the securities.

U.S. Federal Income Tax Consequences of the Exercise and Disposition of Warrants

The following discussion describes the general rules applicable to the ownership and disposition of the Warrants but is subject in its entirety to the special rules described above under the heading "Passive Foreign Investment Company Rules."

Exercise of Warrants

A U.S. Holder should not recognize gain or loss on the exercise of a Warrant and related receipt of a Warrant Share (unless cash is received in lieu of the issuance of a fractional Warrant Share). A U.S. Holder's initial tax basis in the Warrant Share received on the exercise of a Warrant should be equal to the sum of (a) such U.S. Holder's tax basis in such Warrant plus (b) the exercise price paid by such U.S. Holder on the exercise of such Warrant. It is unclear whether a U.S. Holder's holding period for the Warrant Share received on the exercise of a Warrant would commence on the date of exercise of the Warrant or the day following the date of exercise of the Warrant. If we are a PFIC, a U.S. Holder's holding period for the Warrant Share for PFIC purposes will begin on the date on which such U.S. Holder acquired its Warrant

Disposition of Warrants

A U.S. Holder will recognize gain or loss on the sale or other taxable disposition of a Warrant in an amount equal to the difference, if any, between (a) the amount of cash plus the fair market value of any property received and (b) such U.S. Holder's tax basis in the Warrant sold or otherwise disposed of. Subject to the PFIC rules discussed above, any such gain or loss generally will be a capital gain or loss, which will be long-term capital gain or loss if the Warrant is held for more than one year. Deductions for capital losses are subject to complex limitations under the Code.

Expiration of Warrants Without Exercise

Upon the lapse or expiration of a Warrant, a U.S. Holder will recognize a loss in an amount equal to such U.S. Holder's tax basis in the Warrant. Any such loss generally will be a capital loss and will be long-term capital loss if the Warrants are held for more than one year. Deductions for capital losses are subject to complex limitations under the Code.

Certain Adjustments to the Warrants

Under Section 305 of the Code, an adjustment to the number of Warrant Shares that will be issued on the exercise of the Warrants, or an adjustment to the exercise price of the Warrants, may be treated as a constructive distribution to a U.S. Holder of the Warrants if, and to the extent that, such adjustment has the effect of increasing such U.S. Holder's proportionate interest in the "earnings and profits" or our assets, depending on the circumstances of such adjustment (for example, if such adjustment is to compensate for a distribution of cash or other property to the shareholders). Adjustments to the exercise price of Warrants made pursuant to a bona fide reasonable adjustment formula that has the effect of preventing dilution of the interest of the holders of the Warrants should generally not be considered to result in a constructive distribution. Any such constructive distribution would be taxable whether or not there is an actual distribution of cash or other property. (See more detailed discussion of the rules applicable to distributions made by us at "- Distributions on the Common Shares and Warrant Shares" below).

General Rules Applicable to U.S. Federal Income Tax Consequences of the Acquisition, Ownership, and Disposition of the Common Shares and Warrant Shares

The following discussion describes the general rules applicable to the ownership and disposition of the Common Shares and Warrant Shares, but is subject in its entirety to the special rules described above under the heading "Passive Foreign Investment Company Rules."

Distributions on Common Shares and Warrant Shares

In general, subject to the PFIC rules discussed above, the gross amount of any distribution received by a U.S. Holder with respect to the Common Shares and Warrant Shares (including amounts withheld to pay Canadian withholding taxes) will be included in the gross income of the U.S. Holder as a dividend to the extent attributable to the Company's current and accumulated earnings and profits, as determined under U.S. federal income tax principles. A dividend generally will be taxed to a U.S. Holder at ordinary income tax rates if we are a PFIC for the tax year of such distribution or the preceding tax year. To the extent that a distribution exceeds our current and accumulated "earnings and profits," such distribution will be treated first as a tax-free return of capital to the extent of a U.S. Holder's tax basis in such securities and thereafter as gain from the sale or exchange of such securities (see "Sale or Other Taxable Disposition of the Common Shares and Warrant Shares" below). However, because the Company does not expect to maintain calculations of the Company's earnings and profits in accordance with U.S. federal income tax principles, U.S. Holders should expect that a distribution will generally be treated as a dividend for U.S. federal income tax purposes.

Subject to applicable limitations and provided the Company is eligible for the benefits of the US Treaty or the Common Shares are readily tradable on a United States securities market, dividends paid by the Company to non-corporate US Holders, including individuals, generally will be eligible for the preferential tax rates applicable to long-term capital gains for dividends, provided certain holding period and other conditions are satisfied, including that the Company is not classified as a PFIC in the tax year of distribution or in the preceding tax year. Any amount of distributions treated as dividends generally will not be eligible for the dividends received deduction available to certain corporate U.S. Holders in respect of dividends received from U.S. corporations.

Distributions to a U.S. Holder with respect to the Common Shares or Warrant Shares may be subject to Canadian non-resident withholding tax. Any Canadian withholding tax paid will not reduce the amount treated as received by the U.S. Holder for U.S. federal income tax purposes. However, subject to limitations imposed by U.S. law, a U.S. Holder may be eligible to receive a foreign tax credit for

Sale, Exchange or Other Taxable Disposition of Common Shares and Warrant Shares

Subject to the PFIC rules discussed above, upon a sale, exchange or other taxable disposition of the Common Shares or Warrant Shares, a U.S. Holder will generally recognize a capital gain or loss equal to the difference between the amount realized on such sale, exchange or other taxable disposition and the adjusted tax basis of such Common Shares or Warrant Shares. If any foreign tax is imposed on the sale, exchange or other disposition of the Common Shares or Warrant Shares, a U.S. Holder's amount realized will include the gross amount of the proceeds of the disposition before deduction of the tax. A U.S. Holder's initial tax basis in the Common Shares generally will equal the cost of such Common Shares. Such gain or loss will be a long-term capital gain or loss if the Common Shares have been held for more than one year and will be short-term gain or loss if the holding period is equal to or less than one year. Such gain or loss generally will be considered U.S. source gain or loss for U.S. foreign tax credit purposes. Long-term capital gains of certain non-corporate U.S. Holders are eligible for reduced rates of taxation. For both corporate and non-corporate U.S. Holders, limitations apply to the deductibility of capital losses.

Additional Tax Considerations

Receipt of Foreign Currency

The amount of any distribution paid to a U.S. Holder in foreign currency or on the sale, exchange or other taxable disposition of the securities generally will be equal to the U.S. dollar value of such foreign currency based on the exchange rate applicable on the date of receipt (regardless of whether such foreign currency is converted into U.S. dollars at that time). If the foreign currency received is not converted into U.S. dollars on the date of receipt, a U.S. Holder will have a tax basis in the foreign currency equal to its U.S. dollar value on the date of receipt. Any U.S. Holder who receives payment in foreign currency and engages in a subsequent conversion or other disposition of the foreign currency may have a foreign currency exchange gain or loss that would be treated as ordinary income or loss, and generally will be U.S. source income or loss for foreign tax credit purposes. Different rules apply to U.S. Holders who use the accrual method of tax accounting. Each U.S. Holder should consult its own U.S. tax advisor regarding the U.S. federal income tax consequences of receiving, owning, and disposing of foreign currency.

Foreign Tax Credit

Subject to the PFIC rules discussed above, a U.S. Holder that pays (whether directly or through withholding) Canadian income tax with respect to dividends paid on the securities (or with respect to any constructive dividend on the Warrants) generally will be entitled, at the election of such U.S. Holder, to receive either a deduction or a credit for such Canadian income tax paid. Generally, a credit will reduce a U.S. Holder's U.S. federal income tax liability on a dollar-for-dollar basis, whereas a deduction will reduce a U.S. Holder's income subject to U.S. federal income tax. This election is made on a year-by-year basis and applies to all foreign taxes paid or accrued (whether directly or through withholding) by a U.S. Holder during a year. The foreign tax credit rules are complex and involve the application of rules that depend on a U.S. Holder's particular circumstances. Accordingly, each U.S. Holder should consult its own tax advisor regarding the foreign tax credit rules.

Information Reporting and Backup Withholding

Under U.S. federal income tax laws certain categories of U.S. Holders must file information returns with respect to their investment in, or involvement in, a foreign corporation. For example, U.S. return disclosure obligations (and related penalties) are imposed on U.S. Holders that hold certain specified foreign financial assets in excess of certain threshold amounts. The definition of specified foreign financial assets includes not only financial accounts maintained in foreign financial institutions, but also, unless held in accounts maintained by a financial institution, any stock or security issued by a non-U.S. person, any financial instrument or contract held for investment that has an issuer or counterparty other than a U.S. person, and any interest in a non-U.S. entity. U. S. Holders may be subject to these reporting requirements unless the securities are held in an account at certain financial institutions. Penalties for failure to file certain of these information returns are substantial. U.S. Holders should consult their own tax advisors regarding the requirements of filing information returns, including the requirement to file IRS Form 8938. In addition, U.S. Holders should consult with their own tax advisors regarding the requirements of filing information returns, and, if applicable, filing obligations relating to the PFIC rules, including possible reporting on an IRS Form 8621

Payments made within the U.S., or by a U.S. payor or U.S. middleman, of dividends on, and proceeds arising from the sale or other taxable disposition of the Common Shares generally may be subject to information reporting and backup withholding tax, currently at the rate of 24%, if a U.S. Holder (a) fails to furnish its correct U.S. taxpayer identification number (generally on Form W 9), (b) furnishes an incorrect U.S. taxpayer identification number, (c) is notified by the IRS that such U.S. Holder has previously failed to properly report items subject to backup withholding tax, or (d) fails to certify, under penalty of perjury, that it has furnished its correct U.S. taxpayer identification number and that the IRS has not notified such U.S. Holder that it is subject to backup withholding tax. However, certain exempt persons, such as U.S. Holders that are corporations, generally are excluded from these information reporting and backup withholding tax rules. Any amounts withheld under the U.S. backup withholding tax rules will be allowed as a credit against a U.S. Holder's U.S. federal income tax liability, if any, or will be refunded, if such U.S. Holder furnishes required information to the IRS in a timely manner. The information reporting and backup withholding rules may apply even if, under the Canada-U.S. Tax Convention, payments may be exempt from the dividend withholding tax rules or otherwise eligible for a reduced withholding rate. Each U.S. Holder should consult its own tax advisor regarding the information reporting and backup withholding rules.

The discussion of reporting requirements set forth above is not intended to constitute a complete description of all reporting requirements that may apply to a U.S. Holder. A failure to satisfy certain reporting requirements may result in an extension of the time period during which the IRS can assess a tax and, under certain circumstances, such an extension may apply to assessments of amounts unrelated to any unsatisfied reporting requirement. Each U.S. Holder should consult its own tax advisors regarding the information reporting and backup withholding rules.

THE ABOVE SUMMARY IS NOT INTENDED TO CONSTITUTE A COMPLETE ANALYSIS OF ALL TAX CONSIDERATIONS APPLICABLE TO U.S. HOLDERS WITH RESPECT TO THE ACQUISITION, OWNERSHIP, AND DISPOSITION OF THE SECURITIES. EACH PROSPECTIVE INVESTOR IS URGED TO CONSULT ITS OWN TAX ADVISOR ABOUT THE TAX CONSEQUENCES TO IT OF AN INVESTMENT IN THE SECURITIES IN LIGHT OF THE INVESTOR'S OWN CIRCUMSTANCES.

Notes:

(1) To be provided by a Prospectus Supplement, or as an exhibit to a Report on Form 6-K that is incorporated by reference into this Prospectus.

DISCLOSURE OF COMMISSION POSITION ON INDEMNIFICATION FOR SECURITIES ACT LIABILITIES

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers or persons controlling the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or person controlling the registrant in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

ENFORCEMENT OF CIVIL LIABILITIES

Largo is a corporation governed by the Business Corporations Act (Ontario), and a substantial portion of our assets are outside of the United States. Most of our directors and senior management and independent auditors are resident outside the United States, and all or a substantial portion of their respective assets may be located outside the United States. As a result, it may be difficult for U.S. investors to effect service of process within the United States upon these persons. It may also be difficult for U.S. investors to enforce within the United States judgments predicated upon the civil liability provisions of the securities laws of the United States or any state thereof. In addition, there is uncertainty as to whether the courts outside the United States would recognize or enforce judgments of U.S. courts obtained against us or our directors and officers predicated upon the civil liability provisions of the securities laws of the United States or any state thereof. Therefore, it may be difficult to enforce U.S. judgments against us, our directors and officers and independent auditors.

WHERE YOU CAN GET MORE INFORMATION

We have filed with the SEC a registration statement on Form F-3 under the Securities Act with respect to the securities described in this Prospectus and any accompanying Prospectus Supplement, as applicable. This Prospectus and any accompanying Prospectus Supplement, which constitute a part of that registration statement, do not contain all of the information set forth in that registration statement and its exhibits. For further information with respect to us and our securities, you should consult the registration statement and its exhibits.

We are required to file with the Commissions annual and quarterly reports, material change reports and other information. In addition, we are subject to the informational requirements of the Exchange Act, and, in accordance with the Exchange Act, we also must file reports with, and furnish other information to, the SEC. As a foreign private issuer, we are exempt from the rules under the Exchange Act prescribing the furnishing and content of proxy statements, and our officers, directors and principal shareholders are exempt from the reporting and short-swing profit recovery provisions contained in Section 16 of the Exchange Act. In addition, we are not required to publish financial statements as promptly as United States companies. However, we file with the SEC an annual report on Form 40-F or Form 20-F, as applicable, containing financial statements audited by an independent registered public accounting firm, and we submit to the SEC, on Form 6-K, unaudited quarterly financial information.

The SEC maintains an internet site (www.sec.gov) that makes available reports and other information that we file or furnish electronically with it.

PART II

INFORMATION NOT REQUIRED IN PROSPECTUS

Indemnification of Directors and Officers

Under the Ontario Business Corporations Act ("OBCA"), we may indemnify our current or former directors or officers or another individual who acts or acted at our request as a director or officer, or an individual acting in a similar capacity, of another entity, against all costs, charges and expenses, including an amount paid to settle an action or satisfy a judgment, reasonably incurred by the individual in respect of any civil, criminal, administrative, investigative or other proceeding in which the individual is involved because of his or her association with us or another entity. The OBCA also provides that we may also advance moneys to a director, officer or other individual for costs, charges and expenses incurred in connection with such a proceeding.

However, indemnification is prohibited under the OBCA unless the individual:

Our bylaws require us to indemnify each of our current or former directors or officers and each individual who acts or acted at our request as a director or officer, or an individual acting in a similar capacity, of another entity, against all costs, charges and expenses, including an amount paid to settle an action or satisfy a judgment, reasonably incurred by the individual in respect of any civil, criminal, administrative, investigative or other proceeding to which the individual is made a party by reason of having been a director or officer of the Company or at the request of the Company as a director or officer, or in similar capacity, of another entity, if certain criteria are met, as further described in our bylaws.

Under the OBCA, we are permitted to purchase and maintain insurance for the benefit of each of our current or former directors or officers and each person who acts or acted at our request as a director or officer, or an individual acting in a similar capacity, of another entity.

Insofar as indemnification for liabilities arising under the U.S. Securities Act of 1933, as amended, may be permitted to directors, officers or persons controlling the Registrant pursuant to the foregoing provisions, the Registrant has been informed that in the opinion of the U.S. Securities and Exchange Commission such indemnification is against public policy as expressed in the U.S. Securities Act of 1933, as amended, and is therefore unenforceable.

EXHIBITS

The following exhibits have been filed as part of this Registration Statement.

* To be filed by amendment or as an exhibit to a report pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934, as amended, including any Form 6-K, and incorporated herein by reference if necessary or required by the transaction.

UNDERTAKINGS

(a) The undersigned registrant hereby undertakes:

(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

(i) To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933;

(ii)  To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20 percent change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective registration statement; and

(iii) To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;

Provided, however, that paragraphs (a)(1)(i), (a)(1)(ii) and (a)(1)(iii) of this section do not apply if the registration statement is on Form S-3 or Form F-3 and the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission by the registrant pursuant to section 13 or section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of the registration statement.

(2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(4) To file a post-effective amendment to the registration statement to include any financial statements required by Item 8.A. of Form 20-F at the start of any delayed offering or throughout a continuous offering. Financial statements and information otherwise required by Section 10(a)(3) of the Securities Act of 1933 need not be furnished, provided, that the registrant includes in the prospectus, by means of a post-effective amendment, financial statements required pursuant to this paragraph (a)(4) and other information necessary to ensure that all other information in the prospectus is at least as current as the date of those financial statements. Notwithstanding the foregoing, with respect to registration statements on Form F-3, a post-effective amendment need not be filed to include financial statements and information required by Section 10(a)(3) of the Securities Act of 1933 or Rule 3-19 of Regulation S-X if such financial statements and information are contained in periodic reports filed with or furnished to the Commission by the registrant pursuant to section 13 or section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the Form F-3.

(5) That, for the purpose of determining liability under the Securities Act of 1933 to any purchaser:

(i) Each prospectus filed by the registrant pursuant to Rule 424(b)(3) shall be deemed to be part of the registration statement as of the date the filed prospectus was deemed part of and included in the registration statement; and

(ii) Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5), or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii), or (x) for the purpose of providing the information required by Section 10(a) of the Securities Act of 1933 shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which that prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date.

(6) That, for the purpose of determining liability of the registrant under the Securities Act of 1933 to any purchaser in the initial distribution of the securities:

The undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

(i) Any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;

(ii) Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;

(iii) The portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and

(iv) Any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.

(b) The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant's annual report pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan's annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(c) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act of 1933 and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act of 1933 and will be governed by the final adjudication of such issue.
