ABOUT THIS PROSPECTUS

This prospectus is part of a registration statement that we filed with the Securities and Exchange Commission, or SEC, utilizing a “shelf” registration process. Under this shelf process, we may, from time to time, sell common stock, preferred stock, warrants, and debt securities as described in this prospectus, in one or more offerings.

This prospectus may not be used to sell securities unless accompanied by a prospectus supplement. This prospectus provides you with a general description of the common stock and other securities that we may offer. Each time we sell common stock or other securities, we will provide a prospectus supplement that will contain specific information about the terms of that offering, including the specific amounts, prices and terms of the common stock or other securities offered. The prospectus supplements may also add, update or change information contained in this prospectus. You should read both this prospectus and any prospectus supplement together with the additional information described under the heading “Where You Can Find More Information” and “Incorporation of Certain Documents By Reference.”

This prospectus and any accompanying prospectus supplement do not contain all of the information included in the registration statement as permitted by the rules and regulations of the SEC. For further information, we refer you to the registration statement on Form S-3, including its exhibits. We are subject to the informational requirements of the Securities Exchange Act of 1934 and, therefore, file reports and other information with the SEC. Our file number with the SEC is 1-8491. Statements contained in this prospectus and any accompanying prospectus supplement or other offering material about the provisions or contents of any agreement or other document are only summaries. If SEC rules require that any agreement or document be filed as an exhibit to the registration statement, you should refer to that agreement or document for its complete contents.

Unless otherwise stated or the context otherwise requires, references in this prospectus to “Hecla,” “we,” “our,” “us” or the “Company” refer to Hecla Mining Company and its subsidiaries.

You should rely only on the information contained or incorporated by reference in this prospectus. We have not authorized anyone to provide you with different information. If anyone provides you with different or inconsistent information, you should not rely on it. We are not making an offer to sell these securities in any jurisdiction where the offer or sale is not permitted.

You should not assume that the information provided in this prospectus, any prospectus supplement or any other offering material is accurate as of any date other than the date on the front of those documents, as applicable. Our business, financial condition, results of operations and prospects may have changed since that date.

INFORMATION REGARDING FORWARD-LOOKING STATEMENTS

Certain statements contained in this prospectus and other public filings (including information incorporated by reference) are “forward-looking statements” and are intended to be covered by the safe harbor provided for under Section 27A of the Securities Act of 1933, as amended (the “Securities Act”), and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). Our forward-looking statements include our current expectations and projections about future production, results, performance, prospects and opportunities, including reserves, resources and other mineralization. We have tried to identify these forward-looking statements by using words such as “may,” “might,” “will,” “expect,” “anticipate,” “believe,” “could,” “intend,” “plan,” “estimate” and similar expressions. These forward-looking statements are based on information currently available to us and are expressed in good faith and believed to have a reasonable basis. However, our forward-looking statements are subject to a number of risks, uncertainties and other factors that could cause our actual production, results, performance, prospects or opportunities, including reserves, resources and other mineralization, to differ materially from those expressed in, or implied by, these forward-looking statements.

These risks, uncertainties and other factors include, but are not limited to, those set forth in our Annual Report on Form 10-K for the year ended December 31, 2021, which is incorporated by reference in this prospectus, in any other SEC Reports we file and in this prospectus, including the following:

• a substantial or extended decline in metals prices would have a material adverse effect on us;

• an extended decline in metals prices, an increase in operating or capital costs, mine accidents or closures, increasing regulatory obligations, or our inability to convert resources or exploration targets to reserves may cause us to record write-downs, which could negatively impact our results of operations;

• we have a substantial amount of debt that could impair our financial health and prevent us from fulfilling our obligations under our existing and future indebtedness;

• we have had losses that could reoccur in the future;

• our accounting and other estimates may be imprecise;

• commodity and currency risk management activities could prevent us from realizing possible revenues or lower costs or expose us to losses;

• our ability to recognize the benefits of deferred tax assets related to net operating loss carryforwards and other items is dependent on future cash flows and taxable income;

• returns for investments in pension plans and pension plan funding requirements are uncertain;

• natural disasters, public health crises (including COVID-19), political crises, and other catastrophic events or other events outside of our control may materially and adversely affect our business or financial results;

• the COVID-19 virus pandemic may heighten other risks;

• climate change could negatively our impact operations and financial performance;

• mining accidents or other adverse events at an operation could decrease our anticipated production or otherwise adversely affect our operations;

• our operations may be adversely affected by risks and hazards associated with the mining industry that may not be fully covered by insurance;

• our costs of extending reserves or development of new orebodies and other capital costs may be higher and provide less return than we estimated;

• our ore reserve and resource estimates may be imprecise;

2

• efforts to expand the finite lives of our mines may not be successful or could result in significant demands on our liquidity, which could hinder our growth;

• our ability to market our metals production depends on the availability of smelters and/or refining facilities and our operations and financial results may be affected by disruptions or closures or the unavailability of smelters and/or refining facilities for other reasons;

• we derive a significant amount of revenue from a relatively small number of customers and occasionally enter into concentrate spot market sales with metal traders;

• shortages of critical parts and equipment may adversely affect our operations and development projects;

• our foreign activities are subject to additional inherent risks;

• our operations and properties in Canada expose us to additional political risks;

• certain of our mines and exploration properties are located on land that is or may become subject to traditional territory, title claims and/or claims of cultural significance, and such claims and the attendant obligations of the federal government to those tribal communities and stakeholders may affect our current and future operations;

• we may be subject to a number of unanticipated risks related to inadequate infrastructure;

• we face inherent risks in acquisitions of other mining companies or properties that may adversely impact our growth strategy;

• we may be unable to successfully integrate the operations of the properties we acquire;

• the issues we have faced at our Nevada Operations unit could require us to write-down the associated long-lived assets. We could face similar issues at our other operations. Such write-downs may adversely affect our results of operations and financial condition;

• we may not realize all of the anticipated benefits from our acquisitions;

• the properties we may acquire may not produce as expected, and we may be unable to determine reserve potential, identify liabilities associated with the acquired properties or obtain protection from sellers against such liabilities;

• we face risks relating to transporting our products from our mines, as well as transporting employees and materials at Greens Creek;

• we face substantial governmental regulation, including the Mine Safety and Health Act, various environmental laws and regulations and the 1872 Mining Law;

• our operations are subject to complex, evolving and increasingly stringent environmental laws and regulations. Compliance with environmental regulations, and litigation based on such regulations, involves significant costs and can threaten existing operations or constrain expansion opportunities;

• mine closure and reclamation regulations impose substantial costs on our operations and include requirements that we provide financial assurance supporting those obligations. These costs could significantly increase and we might not be able to provide financial assurance;

• we are required to obtain governmental permits and other approvals in order to conduct mining operations;

• we are currently involved in ongoing legal disputes that may materially adversely affect us;

• our environmental and asset retirement obligations may exceed the provisions we have made;

• new federal and state laws, regulations and initiatives could impact our operations;

• legal challenges could prevent the Rock Creek or Montanore projects from ever being developed;

3

• the titles to some of our properties may be defective or challenged;

• we may be unable to generate sufficient cash to service all of our debt and meet our other ongoing liquidity needs and may be forced to take other actions to satisfy our obligations, which may be unsuccessful;

• the price of our stock has a history of volatility and could decline in the future;

• our Series B preferred stock has a liquidation preference of $50 per share, or $7.9 million;

• we may not be able to pay common or preferred stock dividends in the future;

• our existing stockholders are effectively subordinated to the holders of our 7.25% Senior Notes due 2028 (“Senior Notes”);

• the issuance of additional shares of our preferred or common stock in the future could adversely affect holders of common stock;

• the provisions in our certificate of incorporation, our by-laws and Delaware law could delay or deter tender offers or takeover attempts;

• our Senior Notes and the guarantees thereof are effectively subordinated to any of our and our guarantors’ secured indebtedness to the extent of the value of the collateral securing that indebtedness;

• the terms of our debt impose restrictions on our operations;

• our variable rate indebtedness subjects us to interest rate risk, which could cause our indebtedness service obligations to increase significantly;

• key terms of the Senior Notes will be suspended if the Senior Notes achieve investment grade ratings and no default or event of default has occurred and is continuing;

• we may be unable to repurchase Senior Notes in the event of a change of control as required by the indenture;

• holders of the Senior Notes may not be able to determine when a change of control giving rise to their right to have the Senior Notes repurchased has occurred following a sale of “substantially all” of our assets;

• federal and state fraudulent transfer laws may permit a court to void the Senior Notes or any of the guarantees thereof, and if that occurs, holders of the Senior Notes may not receive any payments on the notes;

• global financial events or developments impacting major industrial or developing countries may have an impact on our business and financial condition in ways that we currently cannot predict;

• tariffs, other potential changes to tariff and import/export regulations, and ongoing trade disputes between the United States and other jurisdictions may have a negative effect on global economic conditions and our business, financial results and financial condition;

• our profitability could be affected by the prices of other commodities;

• our business depends on availability of skilled miners and good relations with employees;

• our information technology systems may be vulnerable to disruption which could place our systems at risk from data loss, operational failure, or compromise of confidential information;

• competition from other mining companies may harm our business;

• additional issuances of equity securities by us would dilute the ownership of our existing stockholders and could reduce our earnings per share;

• if a large number of shares of our common stock are sold in the public market, the sales could reduce the trading price of our common stock and impede our ability to raise future capital; and

4

• any downgrade in the credit ratings assigned to us or our debt securities could increase future borrowing costs, adversely affect the availability of new financing and may result in increased collateral requirements under our existing surety bond portfolio.

Given these risks and uncertainties, readers are cautioned not to place undue reliance on our forward-looking statements. Projections and other forward-looking statements included in this prospectus have been prepared based on assumptions, which we believe to be reasonable, but not in accordance with United States generally accepted accounting principles (“GAAP”) or any guidelines of the SEC. Actual results may vary, perhaps materially. You are strongly cautioned not to place undue reliance on such projections and other forward-looking statements. All subsequent written and oral forward-looking statements attributable to Hecla Mining Company or to persons acting on our behalf are expressly qualified in their entirety by these cautionary statements. Except as required by federal securities laws, we disclaim any intention or obligation to update or revise any forward-looking statements, whether as a result of new information, future events or otherwise.

HECLA MINING COMPANY

Hecla Mining Company and its subsidiaries have provided precious and base metals to the U.S. and worldwide since 1891 (in this prospectus, “we” or “our” or “us” refers to Hecla Mining Company and our affiliates and subsidiaries, unless the context requires otherwise). We discover, acquire and develop mines and other mineral interests and produce and market (i) concentrates containing silver, gold (in the case of Greens Creek), lead and zinc, (ii) carbon material containing silver and gold, and (iii) unrefined doré containing silver and gold. In doing so, we intend to manage our business activities in a safe, environmentally responsible and cost-effective manner.

RISK FACTORS

Investment in our securities involves risks. You should carefully consider the risk factors incorporated by reference to our most recent Annual Report on Form 10-K and any subsequent Quarterly Reports on Form 10-Q or Current Reports on Form 8-K we file after the date of this prospectus, and all other information contained or incorporated by reference into this prospectus, as updated by our subsequent filings under the Exchange Act, as well as the risk factors and other information contained in any prospectus supplement, before acquiring any of such securities. The risks incorporated herein by reference, any of which could materially and adversely affect our business, financial condition, cash flows and results of operations, are the material risks of which we are currently aware; however, they may not be the only risks that we may face. Any of these risks could materially and adversely affect our business, financial condition, results of operations and cash flows. In that case, you may lose all or part of your investment.

7

USE OF PROCEEDS

Unless otherwise indicated in the applicable prospectus supplement, we intend to use the net proceeds of any securities sold for general corporate purposes. This may include, among other things, additions to working capital, repayment or refinancing of existing indebtedness or other corporate obligations, financing of capital expenditures and acquisitions, investment in existing and future projects, and repurchases and redemptions of securities. Pending any specific application, we may initially invest funds in short-term marketable securities or apply them to the reduction of other indebtedness.

8

DESCRIPTION OF CAPITAL STOCK

The following summary is not complete. You should refer to the applicable provisions of our Restated Certificate of Incorporation, and our Bylaws, as amended, and to Delaware corporate law for a complete understanding of the terms and rights of our common and preferred stock.

Common Stock

We are authorized to issue 750,000,000 shares of common stock, $0.25 par value per share, of which 538,352,111 shares of common stock were outstanding as of February 17, 2022. All of our currently outstanding shares of common stock are listed on the New York Stock Exchange under the symbol “HL.”

Subject to the rights of the holders of any outstanding shares of preferred stock, each share of common stock is entitled to: (i) one vote on all matters presented to the stockholders, with no cumulative voting rights; (ii) receive such dividends as may be declared by the Board of Directors out of funds legally available therefor; and (iii) in the event of our liquidation or dissolution, share ratably in any distribution of our assets.

Holders of shares of common stock do not have preemptive rights or other rights to subscribe for unissued or treasury shares or securities convertible into such shares, and no redemption or sinking fund provisions are applicable. All outstanding shares of common stock are fully paid and nonassessable.

Preferred Stock

Our Restated Certificate of Incorporation authorizes us to issue 5,000,000 shares of preferred stock, par value $0.25 per share. The preferred stock is issuable in series with such voting rights, if any, designations, powers, preferences and other rights and such qualifications, limitations and restrictions as may be determined by our Board of Directors. The Board may fix the number of shares constituting each series and increase or decrease the number of shares of any series. As of February 22, 2022, 157,816 shares were outstanding, all of which were shares of Series B preferred stock. All of the shares of our Series B preferred stock are listed on the New York Stock Exchange under the symbol “HL PB.”

Ranking

The Series B preferred stock ranks senior to our common stock and any shares of Series A junior participating preferred stock (none of which have ever been issued) with respect to payment of dividends, and amounts due upon liquidation, dissolution or winding up.

While any shares of Series B preferred stock are outstanding, we may not authorize the creation or issuance of any class or series of stock that ranks senior to the Series B preferred stock as to dividends or amounts due upon liquidation, dissolution or winding up without the consent of the holders of 66 2/3% of the outstanding shares of Series B preferred stock and any other series of preferred stock ranking on a parity with the Series B preferred stock as to dividends and amounts due upon liquidation, dissolution or winding up, voting as a single class without regard to series.

Dividends

Series B preferred stockholders are entitled to receive, when, as and if declared by the Board of Directors out of our assets legally available therefor, cumulative cash dividends at the rate per annum of $3.50 per share of Series B preferred stock. Dividends on the Series B preferred stock are payable quarterly in arrears on October 1, January 1, April 1 and July 1 of each year (and, in the case of any undeclared and unpaid dividends, at such additional times and for such interim periods, if any, as determined by the Board of Directors), at such annual rate. Dividends are cumulative from the date of the original issuance of the Series B preferred stock, whether or not in any dividend period or periods we have assets legally available for the payment of such dividends. Accumulations of dividends on shares of Series B preferred stock do not bear interest.

9

All quarterly dividends on our Series B preferred stock for 2017 through 2021 were declared and paid in cash.

Redemption

The Series B preferred stock is redeemable at our option, in whole or in part, at $50 per share, plus, in each case, all dividends undeclared and unpaid on the Series B preferred stock up to the date fixed for redemption.

Liquidation Preference

The Series B preferred stockholders are entitled to receive, in the event that we are liquidated, dissolved or wound up, whether voluntary or involuntary, $50 per share of Series B preferred stock plus an amount per share equal to all dividends undeclared and unpaid thereon to the date of final distribution to such holders (the “Liquidation Preference”), and no more. Until the Series B preferred stockholders have been paid the Liquidation Preference in full, no payment will be made to any holder of Junior Stock upon our liquidation, dissolution or winding up. The term “junior stock” means our common stock and any other class of our capital stock issued and outstanding that ranks junior as to the payment of dividends or amounts payable upon liquidation, dissolution and winding up to the Series B preferred stock. As of December 31, 2021, our Series B preferred stock had an aggregate Liquidation Preference of $7.9 million.

Voting Rights

Except in certain circumstances and as otherwise from time to time required by applicable law, the Series B preferred stockholders have no voting rights and their consent is not required for taking any corporate action. When and if the Series B preferred stockholders are entitled to vote, each holder will be entitled to one vote per share.

Conversion

Each share of Series B preferred stock is convertible, in whole or in part at the option of the holders thereof, into shares of common stock at a conversion price of $15.55 per share of common stock (equivalent to a conversion rate of 3.2154 shares of common stock for each share of Series B preferred stock). The right to convert shares of Series B preferred stock called for redemption will terminate at the close of business on the day preceding a redemption date (unless we default in payment of the redemption price).

Provisions with Possible Anti-Takeover Effects

The provisions in our Restated Certificate of Incorporation, our Bylaws, as amended, and Delaware law could make it more difficult for a third party to acquire control of us, even if that transaction would be beneficial to stockholders. These impediments include:

• the classification of our Board of Directors into three classes serving staggered three-year terms, which makes it more difficult to quickly replace board members;

• the ability of our Board of Directors to issue shares of preferred stock with rights as it deems appropriate without stockholder approval;

• a provision that special meetings of our Board of Directors may be called only by our chief executive officer or a majority of our Board of Directors;

• a provision that special meetings of stockholders may only be called pursuant to a resolution approved by a majority of our entire Board of Directors;

• a prohibition against action by written consent of our stockholders;

10

• a provision that our board members may only be removed for cause and by an affirmative vote of at least 80% of the outstanding voting stock;

• a provision that our stockholders comply with advance-notice provisions to bring director nominations or other matters before meetings of our stockholders;

• a prohibition against certain business combinations with an acquirer of 15% or more of our common stock for three years after such acquisition unless the stock acquisition or the business combination is approved by our board prior to the acquisition of the 15% interest, or after such acquisition our board and the holders of two-thirds of the other common stock approve the business combination; and

• a prohibition against our entering into certain business combinations with interested stockholders without the affirmative vote of the holders of at least 80% of the voting power of the then outstanding shares of voting stock.

11

DESCRIPTION OF WARRANTS

We may issue warrants for the purchase of our debt securities, preferred stock, or common stock or units of two or more of these types of securities. Warrants may be issued independently or together with debt securities, preferred stock or common stock and may be attached to or separate from these securities. Each series of warrants will be issued under a separate warrant agreement. We will distribute a prospectus supplement with regard to each issue or series of warrants.

Warrants to Purchase Debt Securities

Each prospectus supplement for warrants to purchase debt securities will describe:

• the title of the debt warrants;

• the aggregate number of the debt warrants;

• the price or prices at which the debt warrants will be issued;

• the designation, aggregate principal amount and terms of the debt securities purchasable upon exercise of the debt warrants, and the procedures and conditions relating to the exercise of the debt warrants;

• if applicable, the number of the warrants issued with a specified principal amount of our debt securities or each share of our preferred stock or common stock;

• if applicable, the date on and after which the debt warrants and the related securities will be separately transferable;

• the principal amount of and exercise price for debt securities that may be purchased upon exercise of each debt warrant;

• the maximum or minimum number of the debt warrants which may be exercised at any time;

• if applicable, a discussion of any material federal income tax considerations; and

• any other material terms of the debt warrants and terms, procedures and limitations relating to the exercise of the debt warrants.

Certificates for warrants to purchase debt securities will be exchangeable for new debt warrant certificates of different denominations. Warrants may be exercised at the corporate trust office of the warrant agent or any other office indicated in the prospectus supplement.

Warrants to Purchase Preferred Stock and Common Stock

Each prospectus supplement for warrants to purchase preferred stock or common stock will describe:

• the title of the warrants;

• the securities for which the warrants are exercisable;

• if applicable, the number of the warrants issued with each share of our preferred stock or common stock;

• if applicable, the date on and after which such warrants and the related securities will be separately transferable;

• any provisions for adjustment of the number or amount of shares of our preferred stock or common stock receivable upon exercise of the warrants or the exercise price of the warrants;

• if applicable, a discussion of material federal income tax considerations; and

12

DESCRIPTION OF DEBT SECURITIES

The following is a general description of the debt securities that we may offer from time to time. The particular terms of the debt securities offered by any prospectus supplement and the extent, if any, to which the general provisions described below may apply to those securities will be described in the applicable prospectus supplement. We also may sell hybrid securities that combine certain features of debt securities and other securities described in this prospectus. As you read this section, please remember that the specific terms of a debt security as described in the applicable prospectus supplement and set forth in the relevant supplemental indenture will supplement and may modify or replace the general terms described in this section. If there are differences between the applicable prospectus supplement and this prospectus, the applicable prospectus supplement will control. As a result, the statements we make in this section may not apply to the debt security you purchase.

Senior Notes

On February 19, 2020, we completed an offering of $475 million in aggregate principal amount of our 7.250% Senior Notes due February 15, 2028. The Senior Notes are governed by the Indenture, dated as of February 19, 2020 (the “Indenture”), among the Company and certain of our subsidiaries and The Bank of New York Mellon Trust Company, N.A., as trustee (the “Trustee”), as supplemented by the First Supplemental Indenture, dated as of February 19, 2020 (the “Supplemental Indenture”), among the Company, certain of our subsidiaries and the Trustee. The Indenture and the Supplemental Indenture have been filed as exhibits to the registration statement of which this prospectus is a part and are subject to, and governed by, the Trust Indenture Act of 1939.

We may offer additional Senior Notes, which additional Senior Notes would be issued pursuant to the Indenture and Supplemental Indenture. If we offer additional Senior Notes, we will describe the terms of such notes in a prospectus supplement applicable to such offering. Except as specifically set forth in such prospectus supplement, the general terms of our debt securities discussed below will not apply to the Senior Notes.

Other Debt Securities

The debt securities that we may offer under this prospectus will represent unsecured general obligations of the Company, unless otherwise provided in the prospectus supplement. As indicated in the applicable prospectus supplement, the debt securities will either be senior debt, senior to all future subordinated indebtedness of the Company and pari passu with other current and future unsecured, unsubordinated indebtedness of the Company or, in the alternative, subordinated debt subordinate in right of payment to current and future senior debt or pari passu with other future subordinated indebtedness of the Company. The debt securities will be issued under the Indenture, subject to such amendments or supplemental indentures as are adopted from time to time, including a supplemental indenture that relates to the particular series of debt securities being offered. The following summary of certain provisions of the Indenture does not purport to be complete and is subject to, and qualified in its entirety by, reference to all the provisions of the Indenture, including the definitions therein of certain terms. Capitalized terms used in this section and not defined have the meanings assigned to those terms in the Indenture. Wherever particular sections or defined terms of the Indenture are referred to, it is intended that such sections or defined terms shall be incorporated herein by reference.

General

Unless otherwise indicated in a prospectus supplement, the terms of the debt securities that we may offer under this prospectus will have the following provisions.

The Indenture does not limit the amount of debt securities that may be issued thereunder. Reference is made to the applicable prospectus supplement for the following terms of the debt securities offered pursuant thereto: (i) designation (including whether they are senior debt or subordinated debt and whether such debt is

14

convertible), aggregate principal amount, purchase price and denomination; (ii) the date of maturity; (iii) interest rate or rates (or method by which such rate will be determined), if any; (iv) the dates on which any such interest will be payable and the method of payment (cash or common stock); (v) the place or places where the principal of and interest, if any, on the debt securities will be payable; (vi) any redemption or sinking fund provisions; (vii) any rights of the holders of debt securities to convert the debt securities into other securities or property of the Company; (viii) the terms, if any, on which such debt securities will be subordinate to other debt of the Company; (ix) if other than the principal amount thereof, the portion of the principal amount of the debt securities that will be payable upon declaration of acceleration of the maturity thereof or provable in bankruptcy; (x) any events of default in addition to or in lieu of those described herein and remedies therefor; (xi) any trustees, authenticating or paying agents, transfer agents or registrars or any other agents with respect to the debt securities; (xii) listing (if any) on a securities exchange; (xiii) whether such debt securities will be certificated or in book-entry form; and (xiv) any other specific terms of the debt securities, including any additional events of default or covenants provided for with respect to debt securities, and any terms that may be required by or advisable under United States laws or regulations.

Debt securities may be presented for exchange, conversion or transfer in the manner, at the places and subject to the restrictions set forth in the debt securities and the applicable prospectus supplement. The Company may charge a reasonable fee for such services, subject to the limitations provided in the Indenture.

Debt securities will bear interest at a fixed rate or a floating rate. Debt securities bearing no interest or interest at a rate that, at the time of issuance, is below the prevailing market rate, will be sold at a discount below their stated principal amount. Special United States federal income tax considerations applicable to any such discounted debt securities or to any debt securities issued at par that is treated as having been issued at a discount for United States income tax purposes will be described in the relevant prospectus supplement.

The Indenture does not contain any covenant or other specific provision affording protection to holders of the debt securities in the event of a highly leveraged transaction or a change in control of the Company, except to the limited extent described below under “—Consolidation, Merger and Sale of Assets.” The Company’s restated certificate of incorporation also contains other provisions that may prevent or limit a change of control.

Modification and Waiver

The Indenture provides that modifications and amendments of the Indenture may be made by the Company and the Trustee, with the consent of the holders of a majority in aggregate principal amount of the outstanding Securities issued under the Indenture that are affected by the modification or amendment voting as one class; provided that no such modification or amendment may, without the consent of the holder of each such Security affected thereby, among other things: (1) change the stated maturity of principal of, or any installment of principal of or interest on, any Security, (2) reduce the rate of or extend the time of payment of interest, if any, on any Security or alter the manner of calculation of interest payable on any Security (except as part of any remarketing of the Securities of any series, or any interest rate reset with respect thereto in each case in accordance with the terms thereof), (3) reduce the principal amount or premium, if any, on any Security, (4) make the principal amount or premium, if any, or interest, if any, on any Security payable in any coin or currency other than that provided in any Security, (5) reduce the percentage in principal amount of Securities of any series the holders of which are required to consent to any such supplemental indenture or any waiver of any past default or Event of Default, (6) change any place of payment where the Securities of any series or interest thereon is payable, or (7) impair the right of any holder of a Security to institute suit for any such payment, reduce the amount of the principal of an Original Issue Discount Security that would be due and payable upon an acceleration of the maturity thereof, adversely affect the right of repayment, if any, at the option of the holder or extend the time or reduce the amount of any payment to any sinking fund or analogous obligation relating to any Security. Any amendment or waiver that waives, changes or eliminates any covenant or other provision of the Indenture that has expressly been included solely for the benefit of one or more particular series, or that modifies the rights of the holders of Securities of such series with respect to such covenant or other provision, shall be deemed not to affect the rights under the Indenture of the holders of Securities of any other series.

15

The Indenture provides that a supplemental indenture that changes or eliminates any covenant or other provision of the Indenture that has expressly been included solely for the benefit of one or more particular series of debt securities, or that modifies the rights of the holders of such series with respect to such covenant or other provision, shall be deemed not to affect the rights under the Indenture of the holders of debt securities of any other series.

The Indenture provides, and each supplemental indenture entered into thereunder will provide, that the Company and the Trustee may, without the consent of the holders of any series of debt securities issued thereunder, amend the Indenture or enter into supplemental indentures for one or more of the following purposes: (1) to evidence the succession of another corporation to the Company and the assumption by any such successor of the covenants, agreements and obligations of the Company in the Indenture and in the debt securities issued thereunder, (2) to add any additional Events of Default; (3) to cure any ambiguity, defect or inconsistency; (4) to make any change that does not adversely affect the interests of the holders of any series of debt securities issued thereunder; (5) to establish the form and terms of debt securities issued thereunder; (6) to set forth the conversion rights of any series; and (7) to set forth the provisions regarding subordination of any series.

Events of Default

Unless otherwise provided in any prospectus supplement, the following will be events of default under the Indenture with respect to each series of debt securities issued thereunder: (1) the Company defaults in the payment of interest on any Security of that series when the same becomes due and payable and such Default continues for a period of 30 days; (2) the Company defaults in the payment of the principal of any Security of that series when the same becomes due and payable at maturity, upon redemption or otherwise; (3) the Company fails to comply with any of its other agreements in the Securities of that series or the indenture with respect to that series and such failure continues for the period and after the notice specified in the indenture; (4) the Company pursuant to or within the meaning of any bankruptcy law: (A) commences a voluntary case, (B) consents to the entry of an order for relief against it in an involuntary case, (C) consents to the appointment of a custodian of it or for all or substantially all of its property, or (D) makes a general assignment for the benefit of its creditors; (5) a court of competent jurisdiction enters an order or decree under any bankruptcy law that: (A) is for relief against the Company in an involuntary case, (B) appoints a custodian of the Company or for all or substantially all of its property, or (C) orders the liquidation of the Company, and the order or decree remains unstayed and in effect for 60 days; or (6) an Event of Default provided in the establishing securities resolution or supplemental indenture for that series occurs. Any event of default with respect to particular series of debt securities under the Indenture may be waived by the holders of a majority in aggregate principal amount of the outstanding debt securities of such series (voting as a class), except in each case a failure to pay principal or interest on such debt securities or a default in respect of a covenant or provision which cannot be modified or amended without the consent of each holder affected thereby.

The Company will be required to furnish to the Trustee annually a statement as to its compliance with all conditions and covenants in the Indenture.

The Indenture contains a provision entitling the Trustee to be indemnified by the holders of Securities before proceeding to exercise any trust or power under the Indenture at the request of such holders. The Indenture provides that the holders of a majority in aggregate principal amount of the then outstanding Securities of any series may direct the time, method and place of conducting any proceedings for any remedy available to the Trustee or of exercising any trust or power conferred upon the Trustee with respect to the Securities of such series; provided, however, that the Trustee may decline to follow any such direction if, among other reasons, the Trustee determines in good faith that the actions or proceedings as directed may not lawfully be taken, would involve the Trustee in personal liability or would be unduly prejudicial to the holders of the Securities of such series not joining in such direction. The right of a holder to institute a proceeding with respect to the Indenture is subject to certain conditions precedent including, without limitation, that the holders of not less than 25% in aggregate principal amount of the Securities of such series then outstanding under the Indenture make a request

16

upon the Trustee to exercise its powers under the Indenture, indemnify the Trustee and afford the Trustee reasonable opportunity to act, but the holder has an absolute right to receipt of the principal of, premium, if any, and interest when due on the Securities, to require conversion of Securities if the Securities are convertible at the option of the holder and to institute suit for the enforcement thereof.

Consolidation, Merger and Sale of Assets

The Indenture provides that the Company may not consolidate with, merge into or sell, convey or lease all or substantially all of its assets to any person unless the Company is the surviving corporation or the successor person is a corporation organized under the laws of any domestic or Canadian jurisdiction and assumes the Company’s obligations on the debt securities issued thereunder, and under the Indenture, and after giving effect thereto, no event of default, and no event that, after notice or lapse of time or both, would become an event of default, shall have occurred and be continuing, and that certain other conditions are met.

The Company will also comply with the other provisions of § 314(a) of the Trust Indenture Act of 1939. Delivery of such reports, information and documents to the Trustee is for informational purposes only and the Trustee’s receipt of such shall not constitute notice or constructive notice of any information contained therein or determinable from information contained therein, including the Company’s compliance with any of its covenants hereunder (as to which the Trustee is entitled to rely exclusively on Officers’ Certificates).

Compliance Certificate. The Company shall deliver to the Trustee, no later than May 1 of each year (beginning with the first May 1 following the first date of issuance of any Securities under the Indenture), a brief certificate signed by the principal executive officer, principal financial officer or principal accounting officer of the Company, as to the signer’s knowledge of the Company’s compliance with all conditions and covenants contained in the Indenture (determined without regard to any period of grace or requirement of notice provided herein).

Discharge, Defeasance and Covenant Defeasance

The Indenture provides with respect to each series of Securities issued thereunder that the Company may terminate its obligations under such Securities of a series and the Indenture with respect to Securities of such series when (1) either (A) all Securities theretofore authenticated and delivered (other than (i) Securities which have been destroyed, lost or stolen and which have been replaced or paid and (ii) Securities for whose payment money has theretofore been deposited in trust or segregated and held in trust by the Company and thereafter repaid to the Company or discharged from such trust) have been delivered to the Trustee for cancellation; or (B) all such Securities not theretofore delivered to the Trustee for cancellation (i) have become due and payable, or (ii) will become due and payable at their stated maturity within one year, or (iii) are to be called for redemption within one year under arrangements satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the name, and at the expense, of the Company, and the Company in the case of (i), (ii), and (iii) above, has deposited or caused to be deposited with the Trustee for that purpose an amount of money or U.S. Government Obligations sufficient to pay and discharge the entire indebtedness on such Securities not theretofore delivered to the Trustee for cancellation, for principal and interest to the date of such deposit (in the case of Securities which have become due and payable) or to the stated maturity or redemption date, as the case may be; (2) the Company has paid or caused to be paid all other sums payable under the Indenture by the Company; and (3) the Company has delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent therein provided for relating to the satisfaction and discharge of the Indenture have been complied with.

DESCRIPTION OF GUARANTIES

We will set forth in the applicable prospectus supplement a description of any guaranties that may be offered pursuant to this prospectus. The guaranties will be governed by the laws of the State of New York.

PLAN OF DISTRIBUTION

The securities being offered by this prospectus may be sold by us:

• through agents;

• to or through underwriters;

• through broker-dealers (acting as agent or principal);

• directly by us to purchasers, through a specific bidding or auction process or otherwise; or

• through a combination of any such methods of sale.

The distribution of securities may be effected from time to time in one or more transactions, including block transactions and transactions on the New York Stock Exchange or any other organized market where the securities may be traded. The securities may be sold at a fixed price or prices, which may be changed, or at market prices prevailing at the time of sale, at prices relating to the prevailing market prices or at negotiated prices. The consideration may be cash or another form negotiated by the parties. Agents, underwriters or broker-dealers may be paid compensation for offering and selling the securities. That compensation may be in the form of discounts, concessions or commissions to be received from us or from the purchasers of the securities. Dealers and agents participating in the distribution of the securities may be deemed to be underwriters, and compensation received by them on resale of the securities may be deemed to be underwriting discounts. If such dealers or agents were deemed to be underwriters, they may be subject to statutory liabilities under the Securities Act.

Agents may from time to time solicit offers to purchase the securities. If required, we will name in the applicable prospectus supplement any agent involved in the offer or sale of the securities and set forth any compensation payable to the agent. Unless otherwise indicated in the prospectus supplement, any agent will be acting on a best efforts basis for the period of its appointment. Any agent selling the securities covered by this prospectus may be deemed to be an underwriter, as that term is defined in the Securities Act, of the securities.

If underwriters are used in a sale, securities will be acquired by the underwriters for their own account and may be resold from time to time in one or more transactions, including negotiated transactions, at a fixed public offering price or at varying prices determined at the time of sale, or under delayed delivery contracts or other contractual commitments. Securities may be offered to the public either through underwriting syndicates represented by one or more managing underwriters or directly by one or more firms acting as underwriters. If an underwriter or underwriters are used in the sale of securities, an underwriting agreement will be executed with the underwriter or underwriters at the time an agreement for the sale is reached. The applicable prospectus supplement will set forth the managing underwriter or underwriters, as well as any other underwriter or underwriters, with respect to a particular underwritten offering of securities, and will set forth the terms of the transactions, including compensation of the underwriters and dealers and the public offering price, if applicable. The prospectus and prospectus supplement will be used by the underwriters to resell the securities.

If a dealer is used in the sale of the securities, we or an underwriter will sell the securities to the dealer, as principal. The dealer may then resell the securities to the public at varying prices to be determined by the dealer at the time of resale. To the extent required, we will set forth in the prospectus supplement the name of the dealer and the terms of the transactions.

We may directly solicit offers to purchase the securities and we may make sales of securities directly to institutional investors or others. These persons may be deemed to be underwriters within the meaning of the Securities Act with respect to any resale of the securities. To the extent required, the prospectus supplement will describe the terms of any such sales, including the terms of any bidding or auction process, if used.

20

Agents, underwriters and dealers may be entitled under agreements which may be entered into with us to indemnification by us against specified liabilities, including liabilities incurred under the Securities Act, or to

contribution by us to payments they may be required to make in respect of such liabilities. If required, the prospectus supplement will describe the terms and conditions of such indemnification or contribution. Some of the agents, underwriters or dealers, or their affiliates may be customers of, engage in transactions with or perform services for us or our subsidiaries in the ordinary course of business.

Under the securities laws of some states, the securities offered by this prospectus may be sold in those states only through registered or licensed brokers or dealers.

Any person participating in the distribution of common stock registered under the registration statement that includes this prospectus will be subject to applicable provisions of the Exchange Act, and the applicable SEC rules and regulations, including, among others, Regulation M, which may limit the timing of purchases and sales of any of our common stock by any such person. Furthermore, Regulation M may restrict the ability of any person engaged in the distribution of our common stock to engage in market-making activities with respect to our common stock. These restrictions may affect the marketability of our common stock and the ability of any person or entity to engage in market-making activities with respect to our common stock.

Certain persons participating in an offering may engage in over-allotment, stabilizing transactions, short-covering transactions and penalty bids in accordance with Regulation M under the Exchange Act that stabilize, maintain or otherwise affect the price of the offered securities. For a description of these activities, see the information under the heading “Underwriting” in the applicable prospectus supplement.

PART II

INFORMATION NOT REQUIRED IN PROSPECTUS

Item 14. Other Expenses of Issuance and Distribution.

The expenses relating to the registration of the securities will be borne by the registrant. Such expenses (excluding underwriting discounts and commissions) are estimated to be as follows:

Securities and Exchange Commission Registration Fee	$	#
Trustee Fees		*
Transfer Agents’ Fees and Expenses		*
Printing and Engraving Fees and Expenses		*
Accounting Fees and Expenses		*
Legal Fees		*
Miscellaneous		*
Total	$	*

# To be determined. The registrant is deferring payment of the registration fee in reliance on Rule 456(b) and 457(r).

* As the types and amounts of securities to be issued and distributed pursuant to this registration statement may vary, the fees and expenses of such issuances and distributions cannot be reasonably determined or estimated at this time.

Item 15. Indemnification of Directors and Officers.

The Registrant is organized as a corporation under Delaware law and is subject to the provisions of the General Corporation Law of the State of Delaware (the “DGCL”). The following description is intended only as a summary and is qualified in its entirety by reference to the Restated Certificate of Incorporation of the Registrant, the Bylaws of the Registrant and the DGCL.

Pursuant to the DGCL, a corporation may indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of such corporation) by reason of the fact that such person is or was a director, officer, employee or agent of such corporation, or is or was serving at the request of such corporation in such capacity for another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by such person in connection with such action, suit or proceeding, if such person acted in good faith and in a manner such person reasonably believed to be in or not opposed to the best interests of such corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe his or her conduct was unlawful.

The DGCL also permits indemnification by a corporation under similar circumstances for expenses (including attorneys’ fees) actually and reasonably incurred by such persons in connection with the defense or settlement of an action by or in the right of such corporation, except that no indemnification shall be made in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable to such corporation unless and only to the extent that the Delaware Court of Chancery or the court in which such action or suit was brought shall determine upon application that such person is fairly and reasonably entitled to indemnity for such expenses which such court shall deem proper.

To the extent that a present or former director or officer is successful in the defense of such an action, suit or proceeding (or of any claim, issue or matter therein), the corporation is required by the DGCL to indemnify such person for actual and reasonable expenses (including attorneys’ fees) incurred thereby.

II-1

Expenses (including attorneys’ fees) incurred by a director or officer in defending any civil, criminal, administrative or investigative action, suit or proceeding may be paid (on terms and conditions satisfactory to the corporation) in advance of the final disposition of such action, suit or proceeding upon receipt of an undertaking by or on behalf of such person to repay such amount if it is ultimately determined that such person is not entitled to be so indemnified.

The DGCL provides that the indemnification and advancement of expenses described above shall not be deemed exclusive of other indemnification or advancement of expenses that may be granted by a corporation pursuant to its Bylaws, a disinterested director vote, a stockholder vote, an agreement or otherwise.

The DGCL also provides corporations with the power to purchase and maintain insurance on behalf of any person who is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation in a similar capacity for another corporation, partnership, joint venture, trust or other enterprise, against any liability asserted against such person in any such capacity, or arising out of such person’s status as such, whether or not the corporation would have the power to indemnify such person against such liability as described above.

Accordingly, the Bylaws of the Registrant, to the fullest extent permitted by applicable law, indemnify and hold harmless each person (each, a “Covered Person”) who is or was a director, officer or employee of the Registrant or, while a director, officer or employee of the Registrant, is or was serving at the request of the Registrant as a director, officer or employee or agent of another corporation, or of a partnership, joint venture, trust, enterprise or non-profit entity, including service with respect to employee benefit plans. However, the Registrant shall be required to indemnify any person seeking indemnification in connection with a proceeding initiated by such person only if such proceeding was authorized by the Board of Directors or is a proceeding to enforce such person’s claim to indemnification pursuant to the rights granted by the Bylaws or otherwise by the Registrant. The Registrant may also enter into one or more agreements with any person which provide for indemnification greater or different than that provided in the Registrant’s Restated Certificate of Incorporation.

The Bylaws of the Registrant also provide that the Registrant shall, to the fullest extent not prohibited by applicable law, pay the expenses (including attorneys’ fees) incurred by a Covered Person in defending any proceeding in advance of its final disposition, provided, however, that, to the extent required by law, such payment of expenses in advance of the final disposition of the proceeding shall be made only upon receipt of an undertaking by such Covered Person to repay all amounts advanced if it should be ultimately determined that such Covered Person is not entitled to be indemnified.

The Bylaws of the Registrant also provide that the Registrant’s obligation, if any, to indemnify or to advance expenses to any Covered Person who was or is serving at its request as a director, officer, employee or agent of another corporation, partnership, joint venture, trust, enterprise or non-profit entity shall be reduced by any amount such Covered Person may collect as indemnification or advancement of expenses from such other corporation, partnership, joint venture, trust, enterprise or non-profit entity.

Furthermore, pursuant to the Restated Certificate of Incorporation of the Registrant, as permitted under the DGCL, a director of the Registrant shall not be personally liable to the Registrant or its stockholders for monetary damages for breach of such person’s fiduciary duty as a director, except for liability (1) for any breach of such person’s duty of loyalty to the Registrant or its stockholders, (2) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (3) under Section 174 of the DGCL or (4) for any transaction from which he or she derived an improper personal benefit.

The DGCL permits, and the Registrant has, liability insurance for the benefit of its directors and officers.

Item 17. Undertakings.

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;

(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 (1)(i), (1)(ii) and (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) 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

II-3

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.

(5) 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.

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.

The undersigned registrant hereby undertakes to file an application for the purpose of determining the eligibility of the trustee to act under subsection (a) of section 310 of the Trust Indenture Act (“Act”) in accordance with the rules and regulations prescribed by the Commission under section 305(b)(2) of the Act.

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.
