(1)		“EBITDA” and “adjusted EBITDA” are non-GAAP financial measures. Set forth below is a reconciliation of EBITDA and adjusted EBITDA to net income, the most directly comparable financial measure calculated and presented in accordance with Canadian GAAP.

		EBITDA is calculated as earnings before interest, income taxes, depreciation and amortization. Adjusted EBITDA is calculated as earnings before interest, income taxes, depreciation and amortization, and impairment charges. We use EBITDA and adjusted EBITDA as supplemental financial measures of our operational performance. Management believes EBITDA and adjusted EBITDA to be important measures as they exclude the effects of items which primarily reflect the impact of long-term investment decisions, rather than the performance of our day-to-day operations. As compared to net income according to GAAP, these measures are limited in that they do not reflect the periodic costs of certain capitalized tangible and intangible assets used in generating revenues in our business, or the non-cash charges associated with impairments. Management evaluates such items through other financial measures such as capital expenditures and cash flow provided by operating activities. We believe that these measurements are useful to measure a company’s ability to service debt and to meet other payment obligations or as a valuation measurement.
(2)		“Free cash flow” is a non-GAAP financial measure. Set forth below is a reconciliation of free cash flow to cash provided by operating activities, the most directly comparable financial measure calculated and presented in accordance with Canadian GAAP.

		We use free cash flow as a supplemental financial measure in our evaluation of liquidity and financial strength. Management believes that adjusting principally for the swings in non-cash operating working capital items due to seasonality, additions to property, plant and equipment, purchases of long-term investments, and changes to other assets assists management in the long-term assessment of liquidity and financial strength. We also believe that this measurement is useful as an indicator of our ability to service our debt, meet other payment obligations and make strategic investments. Readers should be aware that free cash flow does not represent residual cash flow available for discretionary expenditures.
(3)		Effective January 21, 2009, our 364-day credit facility was amended to increase available borrowings to $1,500.0 and to extend the maturity date to May 28, 2010. The amount available under the credit facility was again increased on March 5, 2009 to $1,850.0. As the credit facility was extended for a period greater than one year, draws made under it during the first quarter of 2009 have been classified as long-term debt obligations. Outstanding borrowings at March 31, 2009 were $555.0. Draws of $1,000.0 under this pre-amended facility at December 31, 2008 were classified as short-term debt.

Ranking		The notes will be our senior unsecured obligations and will rank equally in right of payment with all of our existing and future senior unsecured indebtedness.
Covenants		We will issue the notes under an indenture containing covenants that restrict our ability to:
		• incur debt secured by liens; and
		• engage in certain sale and leaseback transactions.
		These covenants are subject to important exceptions and qualifications. For more information on these covenants, please see the information under the caption “Description of Debt Securities — Certain Covenants” in the accompanying prospectus.
Change of Control		Upon the occurrence of both (1) a change of control and (2) a downgrade of a particular series of notes below an investment grade rating by each of Moody’s Investors Service, Inc. and Standard & Poor’s Ratings Services within a specified period, we will be required to make an offer to purchase such series of notes at a price equal to 101% of the aggregate principal amount of such notes, plus accrued and unpaid interest to the date of repurchase. See “Description of the Notes — Change of Control” in this prospectus supplement.
Optional Redemption		We may redeem the notes of either series, in whole or in part, at our option at any time and from time to time at a redemption price equal to the greater of:

		360-day year consisting of twelve 30-day months) at the Adjusted Treasury Rate (as defined herein) plus      basis points for the Notes due           and      basis points for the Notes due          .

Additional Amounts		Payments made by us with respect to the notes will be made without withholding or deduction for Canadian taxes, unless we are required to withhold or deduct Canadian taxes by law. If we are required to withhold or deduct for Canadian taxes with respect to any payment made regarding the notes, we will pay such additional amounts as may be necessary so that the net amount received by the holders of the notes after such deduction or withholding is not less than the amount such holders would have received in the absence of the withholding or deduction. See “Description of Debt Securities — Certain Covenants — Additional Amounts” in the accompanying prospectus.
Use of Proceeds		We estimate the net proceeds from the sale of the notes to be approximately $      million after deducting underwriting discounts and commissions and expenses of the offering. We intend to use the net proceeds to repay outstanding indebtedness under our $1,850.0 million revolving credit facility maturing May 28, 2010 and our $750.0 million revolving credit facility maturing May 31, 2013, and for general corporate purposes. See “Use of Proceeds” in this prospectus supplement.

You should carefully consider all the information included in this prospectus supplement, the accompanying prospectus and the documents filed with the Commission that are incorporated by reference herein and therein and, in particular, the risks described below and the risk factors of PotashCorp in Item 1A of our Annual Report on Form 10-K for the fiscal year ended December 31, 2008, which is incorporated by reference herein, before making an investment decision. The risks described below or incorporated by reference herein are not the only ones facing PotashCorp. Additional risks not presently known to us or that we currently deem immaterial may also impair our business operations and the risks described below and in the documents incorporated by reference may also adversely affect our business in ways we have not described or do not currently anticipate. Our business, financial condition or results of operations could be materially adversely affected by any of these risks. In such case, you may lose all or part of your original investment.

 

The notes are unsecured and are subordinated to all of our existing and future secured indebtedness.

 

The notes are unsecured and effectively subordinated in right of payment to all of our existing and future secured indebtedness, to the extent of the value of the assets securing such indebtedness. The indenture for the notes does not restrict our ability to incur additional indebtedness, including secured indebtedness generally, which would have a prior claim on the assets securing that indebtedness. In the event of our insolvency, bankruptcy, liquidation, reorganization, dissolution or winding up, our assets that serve as collateral for any secured indebtedness would be made available to satisfy the obligations to our secured creditors before any payments are made on the notes. See “Description of Debt Securities — General” in the accompanying prospectus.

 

The notes are effectively subordinated to all liabilities of our subsidiaries.

 

None of our subsidiaries has guaranteed or otherwise become obligated with respect to the notes. Accordingly, our right to receive assets from any of our subsidiaries upon its bankruptcy, liquidation or reorganization, and the right of holders of the notes to participate in those assets, is effectively subordinated to claims of that subsidiary’s creditors, including trade creditors.

 

We have made only limited covenants in the indenture for the notes.

 

The indenture for the notes does not:

 

 

The notes have no prior public market and we cannot assure you that any public market will develop or be sustained after the offering.

 

The notes are new issues of securities with no established trading markets. We do not intend to apply for listing of the notes of either series on any national securities exchange or for quotation of the notes on any automated dealer quotation system. We have been advised by the underwriters that they presently intend to make a market in the notes of each series after completion of the offering. However, they are under no obligation to do so and may discontinue any market-making activities at any time without any notice. We cannot assure you that active trading markets for the notes will develop, be maintained or be liquid. If active trading markets for the notes do not develop, are not maintained or are not liquid, the market prices of the notes may be adversely affected.

 

We may be unable to repurchase the notes upon a Change of Control Triggering Event.

 

Upon the occurrence of a Change of Control Triggering Event (as defined herein) with respect to a particular series of notes, subject to certain conditions, we will be required to make an offer to repurchase all outstanding notes of such series at 101% of their principal amount, plus accrued and unpaid interest. See “Description of the Notes — Change of Control” in this prospectus supplement. The source of funds for such a repurchase will be our available cash or cash generated from our subsidiaries’ operations or other potential sources, including borrowings, sales of assets or sales of equity. We cannot assure you that sufficient funds from such sources will be available at the time of any Change of Control Triggering Event to make required repurchases of notes tendered. In addition, the terms of certain of our other existing indebtedness provide that certain change of control events will require us to make an offer to repurchase such outstanding indebtedness. Our future debt instruments may contain similar provisions. It is possible that we will not have sufficient funds at the time of the Change of Control Triggering Event to complete the required repurchase of the notes and, if applicable, our other indebtedness.

 

We estimate the net proceeds from the sale of the notes to be approximately $      million after deducting underwriting discounts and commissions and expenses of the offering. We intend to use the net proceeds to repay outstanding indebtedness under our $1,850.0 million revolving credit facility maturing May 28, 2010 and our $750.0 million revolving credit facility maturing May 31, 2013, and for general corporate purposes. As of April 24, 2009, we had $745.0 million of borrowings outstanding under the $1,850.0 million credit facility and $650.0 million of borrowings outstanding under the $750.0 million credit facility. As of April 24, 2009, the weighted average interest rate applicable to borrowings under the $1,850.0 million credit facility was 3.50%, and the weighted average interest rate applicable to borrowings under the $750.0 million credit facility was 0.96%. We used the proceeds from borrowings under the credit facilities for share repurchases, capital expenditures and general corporate purposes.

 

The following table sets forth our cash and cash equivalents and consolidated capitalization (including short-term debt) as of December 31, 2008 on an actual basis and on an as adjusted basis to give effect to the sale of the notes and the application of the net proceeds from the sale of the notes. You should read the information in this table in conjunction with PotashCorp’s audited consolidated financial statements, which are incorporated by reference into this prospectus supplement and the accompanying prospectus. See “Incorporation by Reference” in this prospectus supplement.

 

 

 

 

The following table sets forth our consolidated ratios of earnings to fixed charges computed using amounts reported under Canadian GAAP and U.S. GAAP for the periods indicated below. Earnings for this purpose have been calculated by adding income taxes, fixed charges and distributed income of equity investees to net income, and deducting interest capitalized and income from equity investees. Fixed charges for this purpose consist of the total of interest expensed and capitalized, amortization of capitalized expenses related to indebtedness and an estimate of the interest within rental expense.

 

 

The following description of the particular terms of the notes offered by this prospectus supplement adds information to the description of the general terms and provisions of debt securities under the heading “Description of Debt Securities” beginning on page 5 of the accompanying prospectus. As used under “Prospectus Supplement Summary — The Offering” and under this heading, “Description of the Notes,” all references to “we,” “us,” “our,” “PotashCorp” and the “Company” refer to Potash Corporation of Saskatchewan Inc. excluding any of its subsidiaries.

 

General

 

We will issue the     % Notes due           in the aggregate principal amount of $           and the     % Notes due           in the aggregate principal amount of $           pursuant to an indenture dated as of February 27, 2003 between us and The Bank of Nova Scotia Trust Company of New York, the trustee for the notes. The     % Notes due           will mature on          ,     , and the     % Notes due           will mature on          ,     . We will issue the notes only in book-entry form, in denominations of $2,000 and integral multiples of $1,000 in excess thereof.

 

The notes will bear interest at the annual rates shown on the cover of this prospectus supplement and will accrue interest from          , 2009 or from the most recent date to which interest has been paid (or provided for) to but not including the next date upon which interest is required to be paid.

 

Commencing          , 2009, interest will be payable twice a year, on           and          , to the person in whose name a note is registered at the close of business on the           or           that precedes the date on which interest will be paid. Interest on the notes will be paid on the basis of a 360-day year consisting of twelve 30-day months.

 

As contemplated under “Description of Debt Securities — Discharge, Defeasance and Covenant Defeasance” on page 14 of the accompanying prospectus, the satisfaction of certain conditions will permit us to discharge some or all of our obligations under the indenture with respect to the notes. In addition, we may discharge our obligations with respect to certain covenants through covenant defeasance. We refer you to the information under “Description of Debt Securities — Discharge, Defeasance and Covenant Defeasance” in the accompanying prospectus for more information.

 

Except as described in this prospectus supplement or the accompanying prospectus, the indenture for the notes does not contain any covenants or other provisions designed to protect holders of the notes against a reduction in our creditworthiness in the event of a highly leveraged transaction nor does the indenture for the notes prohibit other transactions that might adversely affect holders of the notes, including the incurrence of additional indebtedness. See “Risk Factors — We have made only limited covenants in the indenture for the notes” in this prospectus supplement.

 

Re-opening of the Notes

 

We are initially offering notes in the aggregate principal amount of $          . We may from time to time, without the consent of the holders of the notes, create and issue further notes of a series having the same terms and conditions in all respects as the notes of such series being offered hereby, except for the issue date, the issue price and, in some cases, the first payment of interest thereon. Additional notes issued in this manner will be consolidated with and will form a single series with the notes of such series being offered hereby.

 

Optional Redemption

 

The notes of each series will be redeemable, in whole or in part, at our option at any time and from time to time at a redemption price equal to the greater of:

 

 

together with, in each case, accrued interest on the principal amount of the notes to be redeemed to the date of redemption.

 

In connection with such optional redemption, the following defined terms apply:

 

“Adjusted Treasury Rate” means, with respect to any redemption date, the rate per annum equal to the semi-annual equivalent yield to maturity (computed as of the third business day immediately preceding that redemption date) or interpolated (on a day count basis) of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for that redemption date.

 

“Comparable Treasury Issue” means the United States Treasury security or securities selected by the Independent Investment Banker that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining term of the series of notes to be redeemed.

 

“Comparable Treasury Price” means, with respect to any redemption date, (a) the average of the Reference Treasury Dealer Quotations for that redemption date, after excluding the highest and lowest of such Reference Treasury Dealer Quotations, or (b) if the Independent Investment Banker for the notes obtains fewer than four such Reference Treasury Dealer Quotations, the average of all such quotations.

 

“Independent Investment Banker” means one of the Reference Treasury Dealers appointed by us to act as the “Independent Investment Banker.”

 

“Reference Treasury Dealer” means Banc of America Securities LLC and HSBC Securities (USA) Inc. and their respective successors and two other nationally recognized investment banking firms, each of which is a primary U.S. Government securities dealer in New York City (a “Primary Treasury Dealer”) specified from time to time by us; provided, however, that if any of the foregoing shall cease to be a Primary Treasury Dealer, we shall substitute therefor another nationally recognized investment banking firm that is a Primary Treasury Dealer.

 

“Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any redemption date, the average, as determined by the Independent Investment Banker, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Independent Investment Banker by such Reference Treasury Dealer at 3:30 p.m., New York City time, on the third business day preceding that redemption date.

 

“Remaining Scheduled Payments” means, with respect to each note to be redeemed, the remaining scheduled payments of the principal thereof and interest thereon that would be due after the related redemption date but for such redemption; provided, however, that, if that redemption date is not an interest payment date with respect to such note, the amount of the next succeeding scheduled interest payment thereon will be reduced by the amount of interest accrued thereon to that redemption date.

 

Notice of any redemption will be mailed at least 30 days but not more than 60 days before the redemption date to each holder of the notes to be redeemed. On and after any redemption date, interest will cease to accrue on the notes or any portion thereof called for redemption. On or before any redemption date, we shall deposit with the trustee or with a paying agent money sufficient to pay the redemption price of and accrued interest on the notes to be redeemed on such date. If less than all of a series of notes are to be redeemed, the notes of such series to be redeemed shall be selected by the trustee at our direction by such method as we and the trustee shall deem fair and appropriate. The redemption price shall be calculated by the Independent Investment Banker and we, the trustee and any paying agent for the notes shall be entitled to rely on such calculation.

Change of Control

 

If a Change of Control Triggering Event occurs with respect to a particular series of notes, unless we have exercised our right to redeem such series of notes as described above, we will be required to make an offer to repurchase all, or any part (equal to $2,000 or an integral multiple of $1,000 in excess thereof), of each holder’s notes of such series pursuant to the offer described below (the “Change of Control Offer”) on the terms set forth in the notes. In the Change of Control Offer, we will be required to offer payment in cash equal to 101% of the aggregate principal amount of notes repurchased plus accrued and unpaid interest, if any, on the notes repurchased, to the date of purchase (the “Change of Control Payment”).

 

Within 30 days following any Change of Control Triggering Event with respect to a particular series of notes, we will be required to mail a notice to holders of such series of notes describing the transaction or transactions that constitute the Change of Control Triggering Event and offering to repurchase such series of notes on the date specified in the notice, which date will be no earlier than 30 days and no later than 60 days from the date such notice is mailed (the “Change of Control Payment Date”), pursuant to the procedures required by the notes and described in such notice. We must comply with the requirements of Rule 14e-1 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of a series of notes as a result of a Change of Control Triggering Event. To the extent that the provisions of any securities laws or regulations conflict with the Change of Control provisions of the notes, we will be required to comply with the applicable securities laws and regulations and will not be deemed to have breached our obligations under the Change of Control provisions of the notes by virtue of such conflicts.

 

On the Change of Control Payment Date, we will be required, to the extent lawful, to:

 

 

The paying agent will be required to mail promptly to each holder who properly tendered notes the purchase price for such notes and the trustee will be required to authenticate and mail (or cause to be transferred by book entry) promptly to each such holder a new note equal in principal amount to any unpurchased portion of the notes surrendered, if any; provided that each new note will be in a principal amount of $2,000 or an integral multiple of $1,000 in excess thereof.

 

For purposes of the foregoing discussion of a repurchase at the option of holders, the following definitions are applicable:

 

“Below Investment Grade Rating Event” means the rating on a series of notes is changed from an Investment Grade Rating to below an Investment Grade Rating by each of the Rating Agencies (as defined below) on any date from the date of the public notice of an arrangement that could result in a Change of Control until the end of the 60-day period following public notice of the occurrence of the Change of Control (which 60-day period shall be extended so long as the rating of the applicable series of notes is under publicly announced consideration for possible downgrade by any of the Rating Agencies).

 

“Change of Control” means the occurrence of any of the following: (1) the direct or indirect sale, transfer, conveyance or other disposition (other than by way of merger, amalgamation, arrangement or consolidation), in one or a series of related transactions, of all or substantially all of our properties or assets and those of our subsidiaries taken as a whole to any Person other than us or one of our subsidiaries; (2) the consummation of any transaction (including, without limitation, any merger, amalgamation, arrangement or consolidation) the result of which is that any Person becomes the beneficial owner, directly or indirectly, of more than 50% of the total voting power in the aggregate of all classes of our voting stock normally entitled to vote in elections

of directors; or (3) the first day on which a majority of the members of our Board of Directors are not Continuing Directors.

 

“Change of Control Triggering Event” means the occurrence of both a Change of Control and a Below Investment Grade Rating Event.

 

“Continuing Directors” means, as of any date of determination, any member of our Board of Directors who (1) was a member of such Board of Directors on the date of this prospectus supplement; or (2) was nominated for election or elected to such Board of Directors with the approval of a majority of the Continuing Directors who were members of such Board of Directors at the time of such nomination or election (either by a specific vote or by approval of our proxy statement in which such member was named as a nominee for election as a director, without objection to such nomination).

 

“Investment Grade Rating” means a rating equal to or higher than Baa3 (or the equivalent) by Moody’s and BBB- (or the equivalent) by S&P.

 

“Moody’s” means Moody’s Investors Service, Inc.

 

“Person” means any individual, partnership, corporation, limited liability company, joint stock company, business trust, trust, unincorporated association, joint venture or other entity, or a government or political subdivision or agency thereof.

 

“Rating Agencies” means (1) each of Moody’s and S&P; and (2) if either Moody’s or S&P ceases to rate a series of notes or fails to make a rating of a series of notes publicly available for reasons outside of our control, a “nationally recognized statistical rating organization” within the meaning of Rule 15c3-1(c)(2)(vi)(F) under the Exchange Act, selected by us (as certified by a resolution of our Board of Directors) as a replacement agency for Moody’s or S&P, or both of them, as the case may be.

 

“S&P” means Standard & Poor’s Ratings Services, a division of The McGraw-Hill Companies, Inc.

 

The failure by us to comply with the obligations described under “— Change of Control” will constitute an event of default with respect to such series of notes.

 

Book-Entry System

 

The certificates representing each series of notes will be issued in the form of one or more fully registered global notes without coupons (the “Global Note”) and will be deposited with, or on behalf of, DTC and registered in the name of Cede & Co., as the nominee of DTC. Except in limited circumstances, the notes will not be issuable in definitive form. Unless and until they are exchanged in whole or in part for the individual notes represented thereby, any interests in the Global Note may not be transferred except as a whole by DTC to a nominee of DTC or by a nominee of DTC to DTC or another nominee of DTC or by DTC or any nominee of DTC to a successor depository or any nominee of such successor. See “Legal Ownership of Debt Securities — Global Securities” in the accompanying prospectus.

 

DTC has advised us that DTC is a limited-purpose trust company organized under the New York Banking Law, a “banking organization” within the meaning of the New York Banking Law, a member of the Federal Reserve System, a “clearing corporation” within the meaning of the New York Uniform Commercial Code, and a “clearing agency” registered pursuant to the provisions of Section 17A of the Exchange Act. DTC holds securities that its participants (“Direct Participants”) deposit with DTC. DTC also facilitates the post-trade settlement among Direct Participants of sales and other securities transactions in deposited securities, through electronic computerized book-entry transfers and pledges between Direct Participants’ accounts. This eliminates the need for physical movement of securities certificates. Direct Participants include both U.S. and non-U.S. securities brokers and dealers, banks, trust companies, clearing corporations, and certain other organizations. DTC is a wholly owned subsidiary of The Depository Trust & Clearing Corporation (“DTCC”). DTCC is the holding company for DTC, National Securities Clearing Corporation and Fixed Income Clearing Corporation, all of which are registered clearing agencies. DTCC is owned by the users of its regulated subsidiaries. Access to the DTC system is also available to others such as both U.S. and non-U.S. securities brokers and dealers, banks, trust companies and clearing corporations that clear through or maintain a

custodial relationship with a Direct Participant, either directly or indirectly. The rules applicable to DTC and its participants are on file with the Commission.

 

The information in this section concerning DTC and DTC’s book-entry system has been obtained from sources that we believe to be reliable, but we take no responsibility for the accuracy thereof.

 

Same-Day Funds Settlement and Payment

 

Settlement for the notes will be made by the underwriters in immediately available funds. All payments of principal and interest in respect of notes in book-entry form will be made by us in immediately available funds to the accounts specified by DTC.

 

Secondary trading in long-term notes and debentures of corporate issuers is generally settled in clearing houses or next-day funds. In contrast, the notes will trade in DTC’s Same-Day Funds Settlement System until maturity, or earlier redemption or repayment, or until the notes are issued in certificated form, and secondary market trading activity in the notes will therefore be required by DTC to settle in immediately available funds. No assurance can be given as to the effect, if any, of settlement in immediately available funds on trading activity in the notes.

 

Concerning the Trustee

 

The Bank of Nova Scotia Trust Company of New York is the trustee under the indenture. An affiliate of the trustee is a lender to us under our $750.0 million revolving credit facility maturing May 31, 2013 and our $1,850.0 million revolving credit facility maturing May 28, 2010 and also maintains other normal banking relationships, including the maintenance of depositary accounts, with us and certain of our subsidiaries.

 

Kaye Scholer LLP, our United States tax counsel, has advised that the following is a fair summary of the material U.S. federal income tax consequences to U.S. holders (as defined below) of the acquisition, ownership and disposition of the notes. This discussion is based upon the Internal Revenue Code of 1986, as amended (the “Code”), the U.S. Treasury regulations promulgated thereunder, administrative pronouncements and judicial decisions, all as of the date hereof and all of which are subject to change (possibly with retroactive effect) and differing interpretations. Unless otherwise indicated, this summary addresses only notes purchased at original issue at their initial offering price and applies only to beneficial owners that hold the notes as capital assets (generally, property held for investment) within the meaning of section 1221 of the Code.

 

This summary is intended for general information purposes only and does not address all of the U.S. federal income tax considerations that may be relevant to a particular U.S. holder in light of the holder’s individual circumstances or to holders subject to special rules under U.S. federal income tax laws, such as banks and other financial institutions, insurance companies, real estate investment trusts, regulated investment companies, tax-exempt organizations, partnerships (or entities properly classified as partnerships for U.S. federal income tax purposes) or other pass-through entities, dealers in securities or currencies, traders in securities that elect to use a mark-to-market method of accounting, persons liable for U.S. federal alternative minimum tax, U.S. holders whose functional currency is not the U.S. dollar, persons holding notes as part of a hedging or conversion transaction or a straddle, and holders of 10% or more of our voting shares. The discussion does not address any non-U.S., state, local or non-income tax consequences of the acquisition, ownership or disposition of the notes.

 

As used in this prospectus supplement, the term “U.S. holder” means a beneficial owner of a note that is:

 

 

Prospective purchasers of the notes who are not U.S. holders should consult with their own tax advisor regarding the U.S. federal income and other tax consequences of the acquisition, ownership and disposition of the notes.

 

If a partnership (or other entity properly classified as a partnership for U.S. federal income tax purposes) is a beneficial owner of a note, the tax treatment of a partner will generally depend upon the status of the partner and the activities of the partnership. A beneficial owner of a note that is a partnership and partners in such partnerships are urged to consult with their own tax advisors about the U.S. federal income and other tax consequences of the acquisition, ownership and disposition of the notes.

 

This discussion is for general purposes only and should not be construed as tax advice to any holder of the notes. Holders are urged to consult their own tax advisors regarding the application of the U.S. federal income tax laws to their particular situations and the consequences under federal estate or gift tax laws, as well as non-U.S., state, or local laws and tax treaties, and the possible effects of changes in tax laws. We also refer you to “Canadian Federal Income Tax Considerations.”

Taxation of Interest

 

Interest on notes beneficially owned by a U.S. holder generally will be taxable as ordinary interest income at the time it is paid or accrued in accordance with the U.S. holder’s regular method of accounting for U.S. federal income tax purposes.

 

Sale, Exchange or Redemption of the Notes

 

Upon the sale, exchange, redemption or other taxable disposition of the notes, a U.S. holder generally will recognize gain or loss equal to the difference, if any, between (i) the amount realized upon the sale, exchange, redemption or other taxable disposition, other than amounts attributable to accrued and unpaid interest (which will be taxed as ordinary interest income to the extent such interest has not been previously included in income), and (ii) the U.S. holder’s adjusted tax basis in the notes. The amount realized by a U.S. holder is the sum of the cash plus the fair market value of any other property received on such sale, exchange, redemption or other taxable disposition. A U.S. holder’s adjusted tax basis in the notes generally will be its cost for the notes.

 

The gain or loss a U.S. holder recognizes on the sale, exchange, redemption or other taxable disposition of the notes generally will be capital gain or loss. Such gain or loss generally will be long-term capital gain or loss if a U.S. holder has held the notes for more than one year at the time of such sale, exchange, redemption or other taxable disposition. For certain non-corporate U.S. holders (including individuals), under current law, long-term capital gains are generally taxed at a lower rate than ordinary income. The deductibility of capital losses is subject to limitations. U.S. holders are urged to consult their own tax advisors regarding the deductibility of capital losses in light of their particular circumstances.

 

The gain a U.S. holder recognizes on the sale, exchange, redemption or other taxable disposition of the notes generally will be treated as U.S. source income for U.S. foreign tax credit purposes.

 

Information Reporting and Backup Withholding

 

In general, information reporting requirements will apply to interest and to the proceeds received on the disposition of the notes paid within the United States (and in certain cases, outside the United States) to U.S. holders that are not exempt recipients (such as corporations). In general, a U.S. holder that is not an exempt recipient will be subject to U.S. federal backup withholding tax at the applicable rate (currently 28%) with respect to payments on the notes and the proceeds of a sale, exchange, redemption or other taxable disposition of the notes, unless the U.S. holder provides its taxpayer identification number to the paying agent and certifies, under penalty of perjury, that it is not subject to backup withholding on an Internal Revenue Service Form W-9 (Request for Taxpayer Identification Number and Certification) and otherwise complies with the applicable requirements of the backup withholding rules. Backup withholding is not an additional tax. The amount of any backup withholding from a payment to a U.S. holder may be allowed as a credit against such U.S. holder’s U.S. federal income tax liability and may entitle such U.S. holder to a refund, provided the required information is furnished to the Internal Revenue Service in a timely manner.

 

If you are not a U.S. holder, in order to avoid information reporting and U.S. federal backup withholding tax requirements you will have to comply with certification procedures to establish that you are not a U.S. person.

 

The preceding discussion is only a general summary of certain of the U.S. federal income tax implications of an investment in the notes. Prospective investors are urged to consult with their own tax advisors prior to investing to determine the tax implications of such investment in light of each such investor’s particular circumstances.

 

Davies Ward Phillips & Vineberg LLP, our Canadian tax counsel, has advised that the following is a fair summary of the principal Canadian federal income tax consequences under the Income Tax Act (Canada) and the regulations thereunder (which we refer to in this section as the “Act” and the “Regulations”, respectively) in effect at the date hereof generally applicable to a holder of the notes who:

 

 

Such a holder is hereinafter referred to as a “Non-Resident Holder.”

 

Special rules which are not discussed in this summary may apply to a Non-Resident Holder that is an insurer carrying on business in Canada and elsewhere.

 

This summary is based on the current provisions of the Act and the Regulations, all specific proposals to amend the Act and Regulations publicly announced by or on behalf of the Minister of Finance (Canada) prior to the date hereof (which we refer to in this section as the “Proposals”) and our Canadian counsel’s understanding of the current published administrative practices and policies of the Canada Revenue Agency. This summary assumes that the Act and the Regulations will be amended in accordance with the Proposals as so announced although we cannot assure you that this will occur.

 

This summary does not otherwise take into account or anticipate any changes in law or practice, whether by judicial, governmental or legislative decision or action, nor does it take into account tax legislation of any province, territory or foreign jurisdiction. The provisions of provincial income tax legislation vary from province to province in Canada and in some cases differ from federal income tax legislation. Non-Resident Holders should be aware that the acquisition, holding and disposition of the notes may have tax consequences in the jurisdiction in which they reside which are not described in this prospectus supplement.

 

This summary is of a general nature only and is not intended to be, nor should it be construed to be, legal or tax advice to any particular Non-Resident Holder, and no representations with respect to the income tax consequences to any particular Non-Resident Holder are made. Accordingly, you should consult your own tax advisor for advice with respect to the tax consequences to you of acquiring, holding and disposing of notes, including the application and effect of the income and other tax laws of any country, province, state or local tax authority.

 

Taxation of Interest and Dispositions

 

The payment by the Company of interest, premium, if any, or principal on a note to a Non-Resident Holder will not be subject to Canadian withholding tax under the Act. No other taxes on income (including capital gains) will be payable under the Act in respect of the holding, redemption or disposition of the notes, including a disposition as the result of an optional redemption of a note by us.

The discussion in this section “Canadian Federal Income Tax Considerations” is a summary of certain material Canadian federal income tax considerations for a holder of notes and does not purport to deal with all aspects of Canadian income taxation. For example, the foregoing is not intended to provide any commentary on the income tax consequences and implications to a holder of notes following (a) any of the events or arrangements summarized under “Description of Securities — Discharge, Defeasance and Covenant Defeasance” beginning on page 14 of the accompanying prospectus; (b) a successor entity assuming the payments under the notes as summarized under “Description of Securities — Merger, Consolidation or Sale” beginning on page 8 of the accompanying prospectus; or (c) assumption of obligations under the notes by any other party. Accordingly, no opinion is expressed as to the applicability of any withholding tax to or the income tax treatment of any payments (including proceeds of disposing of the notes) that may be received by holders of the notes following the events or arrangements described under (a), (b) or (c) above.

 

Subject to the terms and conditions contained in an underwriting agreement, we have agreed to sell to the underwriters, for whom Banc of America Securities LLC, HSBC Securities (USA) Inc. and RBC Capital Markets Corporation are acting as representatives, and these underwriters severally have agreed to purchase from us, the principal amount of the notes listed opposite their names below:

 

 

The underwriters have agreed, subject to the terms and conditions of the underwriting agreement, to purchase all of the notes being sold if any of such notes are purchased. If an underwriter defaults, the underwriting agreement provides that the purchase commitments of the non-defaulting underwriters may be increased or the underwriting agreement may be terminated.

 

We have agreed to indemnify the underwriters against certain liabilities, including liabilities under the Securities Act of 1933, as amended, or to contribute to payments the underwriters may be required to make in respect of those liabilities.

 

The underwriters are offering the notes, subject to prior sale, when, as and if issued to and accepted by them, subject to approval of legal matters by their counsel, including the validity of the notes, and other conditions contained in the underwriting agreement, such as the receipt by the underwriters of officer’s certificates and legal opinions. The underwriters reserve the right to withdraw, cancel or modify offers to the public and to reject orders in whole or in part.

 

Commissions and Discounts

 

The underwriters have advised us that they propose initially to offer the notes to the public at the public offering prices set forth on the cover page of this prospectus supplement, and to dealers at this price less a concession not in excess of     % of the principal amount per Note due           and     % of the principal amount per Note due          . The underwriters may allow, and the dealers may reallow, discounts not in excess of     % of the principal amount per Note due      and     % of the principal amount per Note due      to other dealers. After the initial offering of the notes, the public offering price, concessions and discounts may be changed.

 

The following table summarizes the compensation to be paid by us to the underwriters.

 

 

The expenses of the offering, not including the underwriting discount, are estimated to be $      and are payable by us.

 

New Issue of Notes

 

The notes are new issues of securities with no established trading markets. We do not intend to apply for listing of the notes of either series on any national securities exchange or for quotation of the notes on any automated dealer quotation system. We have been advised by the underwriters that they presently intend to make a market in the notes of each series after completion of the offering. However, they are under no obligation to do so and may discontinue any market-making activities at any time without any notice. We cannot assure you that active trading markets for the notes will develop, be maintained or be liquid. If active

trading markets for the notes do not develop, are not maintained or are not liquid, the market prices of the notes may be adversely affected.

 

Price Stabilization and Short Positions

 

In connection with the offering, the underwriters are permitted to engage in transactions that stabilize the market prices of the notes. Such transactions consist of bids or purchases to peg, fix or maintain the price of the notes. If the underwriters create short positions in the notes in connection with the offering, i.e., if they sell more notes than are on the cover page of this prospectus supplement, the underwriters may reduce that short position by purchasing notes in the open market. Purchases of a security to stabilize the price or to reduce a short position could cause the price of the security to be higher than it might be in the absence of such purchases.

 

Neither we nor any of the underwriters make any representation or prediction as to the direction or magnitude of any effect that the transactions described above may have on the prices of the notes. In addition, neither we nor any of the underwriters make any representation that the underwriters will engage in these transactions or that these transactions, once commenced, will not be discontinued without notice.

 

Other Relationships

 

Certain underwriters and their affiliates have engaged in, and may in the future engage in, investment banking, commercial banking and other commercial dealings with us in the ordinary course of business. They have received and will receive customary fees, commissions or other payments for these transactions. Certain of the underwriters or their affiliates have been or are lenders in connection with one or more of our existing credit facilities. In particular, each of the representatives of the underwriters or their affiliates are lenders under our $1,850.0 million revolving credit facility maturing May 28, 2010 and our $750.0 million revolving credit facility maturing May 31, 2013. A portion of the net proceeds of the sale of the notes will be used to reduce our indebtedness to such lenders under our credit facilities. See “Use of Proceeds” and “Capitalization” in this prospectus supplement.

 

Because more than 10% of the net proceeds from the offering may be used to repay indebtedness owed to the underwriters or their affiliates, this offering will be conducted in accordance with Rule 5110(h) of the Financial Industry Regulatory Authority, Inc.

 

Certain matters involving the laws of the United States will be passed upon for us by Jones Day, our United States counsel, and certain matters involving the laws of Canada will be passed upon for us by Stikeman Elliott LLP, our Canadian counsel. Certain matters involving the tax laws of the United States will be passed upon for us by Kaye Scholer LLP, our United States tax counsel. Certain matters involving the tax laws of Canada will be passed upon for us by Davies Ward Phillips & Vineberg LLP, our Canadian tax counsel. Certain matters involving the laws of the United States will be passed upon for the underwriters by Skadden, Arps, Slate, Meagher & Flom LLP.

This prospectus provides you with a general description of the debt securities we may offer. These summary descriptions are not intended to be complete descriptions of the debt securities. Each time we sell debt securities, we will provide one or more prospectus supplements that will contain specific information about the terms of that offering. Those terms may vary from the terms described in this prospectus.

Statements containing words such as “could,” “expect,” “may,” “anticipate,” “believe,” “intend,” “estimate,” “plan” and similar expressions constitute forward-looking statements. These statements are based on certain factors and assumptions as set forth in this document and the documents incorporated by reference herein, including foreign exchange rates, expected growth, results of operations, performance, business prospectus and opportunities, and effective income tax rates.

Some of the factors that could cause actual results or events to differ from current expectations include the following, some of which are described in greater detail in the documents that are incorporated by reference into this prospectus:

 

 

 

These risks and uncertainties are discussed in more detail under the headings “Risk Factors” and “Management’s Discussion and Analysis of Results of Operations and Financial Condition” in our annual report on Form 10-K for the fiscal year ended December 31, 2006 and in other documents and reports filed by us with the SEC and the Canadian provincial securities commissions. You may obtain copies of these documents and reports as described under the heading “Where You Can Find More Information” and “Incorporation by Reference of Certain Documents.”

On May 2, 2007, our Board of Directors approved a three-for-one stock split of our outstanding common shares. The stock split was effected in the form of a stock dividend of two additional common shares for each share owned by shareholders of record at the close of business on May 22, 2007. Information on an adjusted basis, showing the impact of this split for each of 2004, 2005 and 2006 and the first quarter of 2007 is presented in the table below. Comparative results for the second and third quarters of 2007 are also included.

 

 

As required by U.S. federal securities law for all notes and bonds that are publicly offered in the United States, the debt securities offered pursuant to this prospectus are governed by a document called an indenture. The indenture is a contract between us, as issuer, and The Bank of Nova Scotia Trust Company of New York, as trustee. The indenture is incorporated by reference as an exhibit to the registration statement of which this prospectus is a part. The indenture is subject to and governed by the U.S. Trust Indenture Act of 1939, as amended. You should read the indenture for a more complete understanding of the provisions we describe below. Please see “Where You Can Find More Information” for information on how to obtain a copy of the indenture.

 

In the discussion that follows, we summarize particular provisions of the indenture. This discussion is not complete, and is qualified by reference to all the provisions of the indenture, including definitions of terms used in the indenture. For example, in this section we use defined terms that have been given special meaning in the indenture. We describe the meaning for only the more important terms. We also include references in parentheses to certain sections of the indenture. Whenever we refer to particular sections or defined terms of the indenture in this prospectus or in any prospectus supplement, those sections or defined terms are incorporated by reference in this prospectus or in any prospectus supplement.

 

We describe in this section the general terms that will apply to any debt securities that may be offered by us pursuant to this prospectus. At the time that we offer debt securities, we will describe in the related prospectus supplement the specific terms of the offered debt securities and the extent to which the general terms described in this section apply to those debt securities.

 

General

 

Debt securities offered through this prospectus will be limited to an aggregate initial public offering price of $2,000,000,000 or the equivalent in one or more foreign currencies, currency units or composite currencies. The indenture provides that debt securities may be issued thereunder in an unlimited amount. The debt securities may be issued in one or more series, as established by us or as established in the indenture or in one or more indentures supplemental to the indenture. Not all securities of one series need be issued at the same time and, unless otherwise provided, any series may be reopened, without the consent of the holders of the securities of that series, for issuances of additional securities of that series. (Section 3.01)

 

The debt securities described in this prospectus will be direct unsecured obligations of PotashCorp and will rank equally and ratably without preference among themselves and at least equally with all of our other unsecured and unsubordinated indebtedness.

 

The particular terms of each issue of debt securities, as well as any modifications or additions to the general terms of the indenture that may be applicable in the case of that issue of debt securities, will be described in the related prospectus supplement. This description will include, where applicable:

 

 

 

We may issue debt securities as original issue discount securities to be offered and sold at a substantial discount below their stated principal amounts. We will describe in the related prospectus supplement any special U.S. or Canadian federal income tax, accounting and other considerations that may apply to any such original issue discount securities.

 

The prospectus supplement for each offering of debt securities may add to or change statements contained in this prospectus. Except as described in any prospectus supplement, the debt securities will not contain any provisions that would limit our ability to incur unsecured indebtedness or that would afford holders of the debt securities protection in the event of a highly leveraged transaction or that would prohibit other transactions that could adversely affect holders of the debt securities.

 

Form, Denomination, Registration or Transfer

 

Unless otherwise specified in the applicable prospectus supplement, we will issue debt securities only in registered form.

 

We may issue debt securities of a series in whole or in part in the form of one or more global securities. (Section 2.03)

 

Unless otherwise specified in the applicable prospectus supplement, we will issue debt securities denominated in U.S. dollars in integral multiples of $1,000. We will specify the denomination of any series of debt securities denominated in a foreign or composite currency or currency units in the related prospectus

supplement. If applicable, we will issue one or more global securities in a denomination or aggregate denominations equal to the aggregate principal amount of the outstanding debt securities of the series to be represented by such global security or securities. (Sections 3.01 and 3.02)

 

The trustee will act as our agent for registering debt securities in the names of holders and recording transfers of debt securities, although we may appoint another entity to perform this function or perform this function ourselves. The entity performing this function is called the “security registrar.”

 

You may transfer or exchange debt securities at the office of the security registrar. You will not be required to pay any service charge for any registration of transfer or exchange of debt securities, but you may be required to pay for any tax or other governmental charge associated with the transfer or exchange. You may have your debt securities, other than a global security, exchanged for more debt securities of smaller permitted denominations or for fewer debt securities of larger permitted denominations. The transfer or exchange of a debt security will only be made if the security registrar is satisfied with your proof of ownership. (Section 3.05)

 

Neither we nor the trustee will be required to:

 

 

Global Debt Securities

 

We may issue the debt securities of a series in whole or in part in the form of one or more global securities that will be deposited with, or on behalf of, a depositary identified in the related prospectus supplement. Global securities will be registered in the name of the depositary or its nominee. Unless a global security is exchanged in whole or in part for debt securities in definitive form, a global security generally may be transferred only as a whole and only to the depositary or to a nominee of the depositary or to a successor depositary or its nominee. (Sections 3.02 and 3.05)

 

A general description of global securities arrangements is set forth below under “Legal Ownership of Securitie—Global Securities.” The specific terms of the depositary arrangement with respect to any debt securities of a series issued in global form will be described in the prospectus supplement related to such series. We expect that the provisions of the next two paragraphs will apply to all depositary arrangements.

 

Upon the issuance of a global security, the depositary or its nominee will credit, on its book-entry registration and transfer system, the respective principal amounts of the individual debt securities represented by the global security to the accounts of institutions that have accounts with the depositary. These institutions are called “participants.” The participant accounts to be credited will be designated by the underwriters or agents for such debt securities or by us if the debt securities are offered and sold directly by us. Ownership of beneficial interests in a global security will be limited to participants or persons that may hold interests through participants. Ownership of beneficial interests in a global security will be shown on, and the transfer of that interest will be effected only through, records maintained by the depositary or its nominee, or by participants or persons that hold through participants.

 

Upon receipt of any payment in respect of a global security, the depositary or its nominee will immediately credit participants’ accounts with amounts proportionate to their respective beneficial interests in the principal amount of the global security as shown in the records of the depositary or its nominee. Payments by participants to owners of beneficial interests in a global security held through participants will be governed by standing instructions and customary practices and will be the responsibility of those participants.

Payment and Paying Agents

 

Unless otherwise indicated in the applicable prospectus supplement, payment of any installment of interest on debt securities will be made to the person in whose name the debt security is registered at the close of business on the security register at the record date for such interest. The principal of (and applicable premium, if any, on) any series of debt securities will be payable at the corporate trust office of the trustee, which initially will be One Liberty Plaza, New York, New York 10006; except that, at our option, payment of interest may be made by check mailed to each holder at the holder’s registered address or by wire transfer of funds to each holder at an account maintained within the United States. (Sections 3.01, 3.07 and 10.02)

 

If any interest is not punctually paid or provided for on any interest payment date, then interest will stop being payable to the holder on the relevant regular record date and may be paid to the person in whose name the debt security is registered at the close of business on a special record date for the payment of such defaulted interest. A special record date will be fixed by the trustee and notice will be given to the holder of the debt security not more than 15 days and not less than ten days prior to the special record date. In addition, defaulted interest may be paid at any time in any other lawful manner, all as more completely described in the indenture. (Section 3.07)

 

We may appoint one or more paying agents to effect payments in respect of debt securities. We will identify any paying agent for a series of debt securities in the applicable prospectus supplement. We may terminate the appointment of any paying agent at any time, except that we will maintain at least one paying agent in New York City for payments with respect to debt securities of any series payable in U.S. dollars. (Section 10.02)

 

Any money paid to a paying agent in respect of any debt security that remain unclaimed at the end of two years (or such shorter period of time for return of such money to PotashCorp under applicable abandoned property laws) after the relevant amounts shall have become due and payable will be repaid to us. Holders of these debt securities will thereafter look only to us for payment of these amounts. (Section 10.03)

 

Merger, Consolidation or Sale

 

Under the indenture we may amalgamate or consolidate with, or sell, lease or convey all or substantially all of our assets to, or merge with or into, any other entity, provided that:

 

 

Certain Covenants

 

Additional Amounts

 

Payments made by us under or with respect to the debt securities will be free and clear of, and without withholding or deduction for or on account of, any present or future tax, duty, levy, impost, assessment or other governmental charge of any nature whatsoever imposed or levied by or on behalf of the Government of Canada or of any province or territory of Canada or by any authority or agency therein or thereof having power to tax, which we refer to as Taxes, unless we are required to withhold or deduct Taxes by law.

If we are required to withhold or deduct any amount for or on account of Taxes from any payment made with respect to the debt securities, we will pay such additional amounts as may be necessary so that the net amount received by each holder (including additional amounts) after such withholding or deduction will not be less than the amount the holder would have received if the Taxes had not been withheld or deducted; provided that no additional amounts will be payable with respect to certain Taxes specified in the indenture, which we refer to as excluded Taxes. Excluded Taxes include Taxes:

 

 

We will also make such withholding or deduction and remit the full amount deducted or withheld to the relevant authority in accordance with applicable law.

 

We will furnish to the holders of the debt securities certified copies of tax receipts evidencing payment by us within 30 days after the date the payment of any Taxes is due.

 

At least 30 days prior to each date on which any payment under or with respect to the debt securities is due and payable, if we are obligated to pay additional amounts with respect to such payment, we will deliver to the trustee an officer’s certificate stating the fact that such additional amounts will be payable, the amounts payable and such other information necessary to enable the trustee to pay such additional amounts to holders on the payment date. Wherever in this prospectus or a prospectus supplement we mention the payment of the principal of (or premium, if any) or interest on or any other amount payable under, or in respect of, any debt security of any series, we include the payment of additional amounts to the extent that, in such context, additional amounts are, were or would be payable.

 

Our obligation to pay additional amounts if and when due will survive the termination of the indenture and the payment of all amounts under or with respect to the debt securities. (Section 10.06)

 

Limitation on Liens

 

We may not, and we may not permit any of our subsidiaries to, incur any lien on or with respect to any of our or any of our subsidiaries’ principal property (as this term is defined below) owned on or acquired after the date of the indenture to secure debt without making (or causing such subsidiary to make) effective provision for securing the debt securities equally and ratably with such debt as to such principal property for as long as such debt is so secured. If such debt is subordinate to the debt securities, we must secure the debt securities as to such principal property prior to such debt for so long as such debt is so secured.

 

The restrictions on liens will not apply to:

 

 

 

In addition, we and our subsidiaries may incur a lien or liens to secure debt (excluding debt secured by liens permitted under the exceptions listed above) the aggregate amount of which, including attributable debt in respect of sale and leaseback transactions, does not exceed 15% of our consolidated net tangible assets, as such term is defined in the indenture, determined in accordance with Canadian GAAP. We and our subsidiaries may also incur a lien or liens to secure any debt incurred pursuant to a sale and leaseback transaction, without securing the debt securities equally and ratably with or prior to such debt, provided that such sale and leaseback transaction is permitted by the provisions of the indenture described below under “—Limitation on Sale and Leaseback Transactions.” (Section 10.07)

 

For purposes of the limitation on liens covenant and the limitation on sale and leaseback transactions covenant, which is described below, the term “principal property” means any real property interest that is held by us or any of our subsidiaries and that has a gross book value exceeding 5% of our consolidated net tangible assets (other than any interest that our board of directors determines is not material to our business), or any of the capital stock or debt securities issued by any of our significant subsidiaries, as such term is defined in the indenture.

 

Limitation on Sale and Leaseback Transactions

 

We may not, and we may not permit any of our subsidiaries to, enter into any sale and leaseback transaction with respect to any principal property (except for a period, including renewals, not exceeding 36 months) unless:

 

 

 

Notwithstanding the foregoing, in no event will we be required to defease or retire, in the aggregate with respect to any and all such sale and leaseback transactions, more than 25% of the original aggregate principal amount of a series of debt securities on or prior to the fifth anniversary of the original issue date thereof. If the aggregate net proceeds that we would be otherwise required to use to defease or retire securities on or prior to the fifth anniversary of the issue date would exceed 25% of the original aggregate principal amount of such series (such excess we refer to as the 25% excess proceeds), then promptly after such fifth anniversary we will defease or retire securities in an amount equal to the 25% excess proceeds. Pending such defeasing or retiring of securities, the 25% excess proceeds will be invested and maintained by us and for our benefit in permitted short-term investments, and we will not distribute such proceeds in respect of our common shares. (Section 10.08)

 

For purposes of the limitation on sale and leaseback transactions covenant, the term “attributable debt” means, with respect to any sale and leaseback transaction, the present value (discounted at the rate of interest implicit in the terms of the lease) of the obligations of the lessee under the lease for net rental payments during the remaining term of the lease (including any period for which such lease has been extended). For this purpose, “net rental payments” under any lease for any period means the sum of the rental and other payments required to be paid in the period by the lessee, not including, however, any amounts required to be paid by the lessee (whether or not designated as rental or additional rental) on account of maintenance and repairs, insurance, taxes, assessments or similar charges.

 

Events of Default, Notice and Waiver

 

The indenture provides that the following events are events of default with respect to any series of debt securities:

 

 

 

An event of default with respect to a particular series of debt securities will not necessarily constitute an event of default with respect to any other series of debt securities.

 

We are required to file with the trustee annual officers’ certificates as to the absence of specified defaults under the indenture. (Section 10.05)

 

If an event of default with respect to a series of debt securities occurs and is continuing, the trustee will, at the request of holders of not less than 25% in principal amount of the then-outstanding debt securities of the relevant series, declare the principal of, and premium, if any, on, all debt securities of the series to be due and payable, together with accrued interest. The indenture provides that, in certain cases, the holders of a majority in principal amount of the then-outstanding debt securities of a series may on behalf of the holders of all debt securities of that series waive any past default or event of default and rescind and annul any such declaration and its consequences. (Section 5.02)

 

The trustee may require indemnification from the holders of debt securities of a series before proceeding to exercise any right or power under the indenture at the request of those holders. (Section 6.01) The holders of a majority in principal amount of the then-outstanding debt securities of any series may:

 

 

However, the trustee may refuse to follow any direction that conflicts with law or the indenture or is unduly prejudicial to the rights of other holders. (Section 5.12)

 

No holder will be entitled to pursue any remedy with respect to the indenture unless the trustee fails to act for 60 days after it is given:

 

 

and during this 60-day period the holders of a majority in principal amount of all of the then-outstanding debt securities issued under the indenture (treated as a single class) do not give a direction to the trustee that is inconsistent with the enforcement request. (Section 5.07) These provisions will not prevent any holder of debt securities from enforcing payment of the principal of (and premium, if any) and interest on the debt securities at the relevant due dates. (Section 5.08)

If an event of default with respect to a series of debt securities occurs and is continuing, the trustee will mail to the holders of those debt securities a notice of the event of default within 90 days after it occurs. However, except in the case of a default in any payment in respect of a series of debt securities, the trustee shall be protected in withholding notice of an event of default if it determines in good faith that this is in the interests of the holders of the relevant debt securities. (Section 6.02)

 

Modification of the Indenture

 

The indenture provides that, in general, we and the trustee may modify the indenture or the rights of the holders of any debt securities so long as we obtain the consent of the holders of not less than a majority in principal amount of the then-outstanding debt securities affected by the modification. The indenture also provides, however, that we may not effect any modification without the consent of each affected holder if that modification would:

 

 

We and the trustee are permitted to make modifications and amendments to the indenture without the consent of any holder of debt securities for any of the following purposes:

 

 

 

The indenture contains provisions for convening meetings of the holders of debt securities of a series. (Section 15.01) A meeting may be called at any time by the trustee, and also, upon request, by us or by the holders of at least 10% in principal amount of the outstanding debt securities of such series, in any such case upon notice given as provided in the indenture. (Section 15.02) Except for any consent that must be given by the holder of each debt security affected by certain modifications and amendments of the indenture, any resolution presented at a meeting at which a quorum is present may be adopted by the affirmative vote of the holders of a majority in principal amount of the outstanding debt securities of that series. (Section 15.04)

 

Any resolution passed or decision taken at any meeting of holders of debt securities of any series duly held in accordance with the indenture will be binding on all holders of debt securities of that series whether or not present or represented at the meeting. The quorum at any meeting of the holders of debt securities of a series called to adopt a resolution, and at any reconvened meeting, will be persons holding or representing a majority in principal amount of the outstanding debt securities of a series. (Section 15.04)

 

Discharge, Defeasance and Covenant Defeasance

 

We are permitted under the indenture to discharge certain obligations to holders of debt securities that have not already been delivered to the trustee for cancellation and that either have become due and payable or will become due and payable within one year (or scheduled for redemption within one year) by irrevocably depositing with the trustee, in trust, funds in an amount sufficient to pay the entire indebtedness on such debt securities in respect of principal (and premium, if any) and interest to the date of such deposit (if such debt securities have become due and payable) or to the stated maturity and redemption date, as the case may be. (Section 4.01)

 

The indenture provides that we may elect either:

 

 

in either case upon the irrevocable deposit by us with the trustee, in trust, of an amount, in the currency in which those debt securities are payable at stated maturity, or government obligations, or both, applicable to those debt securities that through the scheduled payment of principal and interest in accordance with their terms will provide money in an amount sufficient to pay the principal of (and premium, if any) and interest on those debt securities, and any mandatory sinking fund or analogous payments thereon, on the scheduled due dates. (Section 14.04)

Such a trust will only be permitted to be established if, among other things, we have delivered to the trustee an opinion of counsel to the effect that the holders of such debt securities will not recognize income, gain or loss for U.S. federal income tax purposes as a result of such defeasance or covenant defeasance and will be subject to U.S. federal income tax on the same amounts, in the same manner and at the same times as would have been the case if the defeasance or covenant defeasance had not occurred, and such opinion of counsel, in the case of defeasance, will be required to refer to and be based upon a ruling of the Internal Revenue Service or a change in applicable U.S. federal income tax law occurring after the date of the indenture. (Section 14.04)

 

Governing Law

 

The indenture and the debt securities will be governed by the laws of the State of New York. (Section 1.12)

 

Concerning the Trustee

 

The Bank of Nova Scotia Trust Company of New York is the trustee under the indenture. An affiliate of the trustee is a lender to us under our syndicated credit facility and also maintains other normal banking relations, including the maintenance of depositary accounts, with us and certain of our subsidiaries.

 

“Street Name” and Other Indirect Holders

 

We generally will not recognize investors who hold debt securities in accounts at banks or brokers as legal holders of those debt securities. This is called holding in “street name.” Instead, we recognize only the bank or broker or the financial institution the bank or broker uses to hold the debt securities. These intermediary banks, brokers and other financial institutions pass along principal, interest and other payments on the debt securities, either because they agree to do so in their customer agreements or because they are legally required to do so. If you hold debt securities in street name, you should check with your own institution to find out:

 

 

Registered Holders

 

Our obligations, as well as the obligations of the trustee and any third parties employed by us or the trustee, run only to persons who are registered as holders of debt securities. As noted above, we do not have obligations to you if you hold in street name or through other indirect means, either because you choose to hold debt securities in that manner or because the debt securities are issued in the form of global securities as described below. For example, once we make payment to the registered holder, we have no further responsibility for the payment even if that holder is legally required to pass the payment along to you as a street name customer but does not do so.

 

Global Securities

 

A global security is a special type of indirectly held security. If we choose to issue debt securities in the form of global securities, the ultimate beneficial owners of the debt securities will be indirect holders. We do this by requiring that the global security be registered in the name of a financial institution we select and by requiring that the debt securities represented by the global security not be registered in the name of any other holder except in the special situations described below. The financial institution that acts as the sole registered holder of the global security is called the depositary. Any person wishing to own a debt security may do so indirectly through an account with a broker, bank or other financial institution that in turn has an account with the depositary. The prospectus supplement will indicate whether your series of debt securities will be issued only as global securities.

 

Transfers of debt securities represented by the global security will be made only on the records of the depositary or its nominee by transferring such debt securities from the account of one broker, bank or financial institution to the account of another broker, bank or financial institution. These transfers are made electronically only and are also known as book-entry transfers. Securities in global form are sometimes also referred to as being in book-entry form.

 

As an indirect holder, your rights relating to a global security will be governed by the account rules of your financial institution and of the depositary, as well as general laws relating to securities transfers. We will

not recognize you as a holder of debt securities and instead will deal only with the depositary that holds the global security.

 

You should be aware that if debt securities are issued only in the form of a global security:

 

 

In a few special situations described below, the global security will terminate and the indirect interests in it will be exchanged for registered debt securities represented by physical certificates. After that exchange, the choice of whether to hold debt securities in registered form or in street name will be up to you. You must consult your bank or broker to find out how to have your interests in debt securities transferred to your name, so that you will be a registered holder.

 

Unless we specify otherwise in the prospectus supplement, the special situations for termination of a global security are:

 

 

The prospectus supplement may also list additional situations for terminating a global security that would apply only to the particular series of debt securities covered by the prospectus supplement. When a global security terminates, the depositary (and not us or the trustee) is responsible for deciding the names of the institutions that will be the initial registered holders.

 

The Term “Holder” as Used in this Prospectus and Elsewhere

 

In the descriptions of the debt securities included in this prospectus and any prospectus supplement, when we refer to the “holder” of a given debt security as being entitled to certain rights or payments, or being permitted to take certain actions, we are in all cases referring to the registered holder of the debt security.

 

While you would be the registered holder if you held a certificated security registered in your name, it is likely that the holder will actually be either the broker, bank or other financial institution where you have your street name account, or, in the case of a global security, the depositary. If you are an indirect holder, you will need to coordinate with the institution through which you hold your interest in a debt security in order to determine how the provisions involving holders described in this prospectus and any prospectus supplement will actually apply to you. For example, if the debt security in which you hold a beneficial interest in street name can be repaid at the option of the holder, you cannot exercise the option yourself by following the procedures described in the prospectus supplement. Instead, you would need to cause the institution through which you hold your interest to take those actions on your behalf. Your institution may have procedures and deadlines different from or additional to those described in the prospectus supplement relating to the debt security.

 

The applicable prospectus supplement will describe the principal Canadian federal income tax consequences to an investor who is not resident or deemed to be resident in Canada for purposes of the Income Tax Act (Canada), who is a resident of the United States for purposes of the Canada-United States Income Tax Convention, who deals with us at arm’s length for purposes of the Income Tax Act (Canada) at all times, and who meets certain other requirements, of acquiring, owning and disposing of our debt securities, including whether the payment by us of principal (and premium, if any) and interest will be subject to Canadian non-resident withholding tax under the Income Tax Act (Canada).

 

General

 

We may sell the offered securities (a) through agents; (b) through underwriters or dealers; (c) directly to one or more purchasers; or (d) through a combination of any of these methods of sale.

 

The accompanying prospectus supplement will identify or describe:

 

 

Underwriters, agents and dealers that participate in the distribution of the securities may be “underwriters” as defined in the Securities Act of 1933, or the Securities Act, and any discounts or commissions they receive from us and any profit on their resale of the debt securities may be treated as underwriting discounts and commissions under the Securities Act.

 

The securities described in this prospectus will not be offered or sold to a resident of Canada in contravention of the securities laws of Canada or any province or territory thereof.

 

Underwriters and Agents

 

If we use underwriters for a sale of debt securities, the debt securities will be acquired by the underwriters for their own account. The underwriters may resell the debt securities in one or more transactions, including negotiated transactions at a fixed public offering price or at varying prices determined at the time of sale. Unless otherwise indicated in the related prospectus supplement, the obligations of the underwriters to purchase the debt securities will be subject to various conditions, and the underwriters will be obligated to purchase all the debt securities of the series offered if any of the securities of that series are purchased. Any initial public offering price and any discounts or concessions allowed or reallowed or paid to dealers may be changed from time to time.

 

We may designate agents to solicit purchases for the period of their appointment to sell securities on a continuing basis. Unless otherwise indicated in the related prospectus supplement, any such agent will be acting on a reasonable best efforts basis for the period of its appointment.

 

Any such underwriters or agents may from time to time purchase and sell the debt securities described in this prospectus and the relevant prospectus supplement in the secondary market, but are not obligated to do so. No assurance can be given that there will be a secondary market for the securities or liquidity in the secondary market if one develops. From time to time, those underwriters or agents may make a market in the debt securities but are not obligated to do so.

Dealers

 

We may sell the offered securities to dealers as principals. We may negotiate and pay dealers’ commissions, discounts or concessions for their services. The dealer may then resell such securities to the public either at varying prices to be determined by the dealer or at a fixed offering price agreed to with us at the time of resale. Dealers engaged by us may allow other dealers to participate in resales.

 

Direct Sales

 

We may choose to sell the offered securities directly. In this case, no underwriters or agents would be involved.

 

Indemnification; Other Relationships

 

We may have agreements with any underwriters, agents or dealers to indemnify them against certain civil liabilities, including liabilities under the Securities Act, or to contribute to payments they may be required to make in respect thereof. Underwriters, agents or dealers may engage in transactions with us or our subsidiaries, perform services for us or our subsidiaries or be customers of ours or our subsidiaries in the ordinary course of business.

 

In connection with particular offerings of the debt securities in the future, and if stated in the applicable prospectus supplements, certain matters involving the laws of the United States will be passed upon for us by Jones Day, our United States counsel, and certain matters involving the laws of Canada will be passed upon for us by Stikeman Elliott LLP, our Canadian counsel. Certain matters involving the laws of the United States will be passed upon for any underwriters or agents by Skadden, Arps, Slate, Meagher & Flom LLP.

 

The financial statements as of December 31, 2006 and 2005 and for each of the years in the three-year period ended December 31, 2006, and the related financial statement schedules and management’s report on the effectiveness of internal control over financial reporting as of December 31, 2006 incorporated in this prospectus by reference from our Annual Report on Form 10-K for the fiscal year ended December 31, 2006 have been audited by Deloitte & Touche LLP, independent registered chartered accountants, as stated in their reports (which reports (1) expressed an unqualified opinion on the financial statements and the related financial statement schedule and include a separate report titled Comments by Independent Registered Chartered Accountants on Canada-United States of America Reporting Differences referring to changes in accounting principles; (2) expressed an unqualified opinion on management’s assessment regarding the effectiveness of internal control over financial reporting; and (3) expressed an unqualified opinion on the effectiveness of internal control over financial reporting), which are incorporated in this prospectus by reference and have been so incorporated in reliance upon the reports of such firm given upon their authority as experts in accounting and auditing.

 

We are a corporation organized under the laws of Canada. Certain of our directors and executive officers are residents of Canada. Substantial portions of our assets and of our subsidiaries and such individuals are located outside of the United States. As a result, it may be difficult or impossible to effect service of process within the United States upon such persons within the United States in connection with matters arising under the United States federal securities laws or to enforce against them in United States courts judgments of United States courts predicated upon the civil liability provisions of the United States federal securities laws. There is some doubt as to the enforceability in Canada in original actions, or in actions for enforcement of judgments of United States courts, of civil liabilities predicated upon the United States federal securities laws. In addition, awards for punitive damages in actions brought in the United States or elsewhere may be unenforceable in Canada.
