INDEPENDENT AUDITORS' REPORT

To the Plan Administrator and Participants of the
PCS U.S. Employees' Savings Plan:

We have audited the accompanying statements of net assets available for benefits
of the PCS U.S. Employees' Savings Plan (the "Plan") as of December 31, 2000 and
1999, and the related statement of changes in net assets available for benefits
for the year ended December 31, 2000. These financial statements are the
responsibility of the Plan's management. Our responsibility is to express an
opinion on these financial statements based on our audits.

We conducted our audits in accordance with auditing standards generally accepted
in the United States of America. Those standards require that we plan and
perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.

In our opinion, such financial statements present fairly, in all material
respects, the net assets available for benefits of the Plan as of December 31,
2000 and 1999, and the changes in net assets available for benefits for the year
ended December 31, 2000 in conformity with accounting principles generally
accepted in the United States of America.

Our audits were conducted for the purpose of forming an opinion on the basic
financial statements taken as a whole. The supplemental schedule of assets held
for investment purposes at end of year, as of December 31, 2000 is presented for
the purpose of additional analysis and is not a required part of the basic
financial statements but is supplementary information required by the Department
of Labor's Rules and Regulations for Reporting and Disclosure under the Employee
Retirement Income Security Act of 1974. This schedule is the responsibility of
the Plan's management. Such schedule has been subjected to the auditing
procedures applied in the audit of the basic 2000 financial statements and, in
our opinion, is fairly stated in all material respects when considered in
relation to the basic financial statements taken as a whole.

PCS U.S. EMPLOYEES' SAVINGS PLAN

NOTES TO FINANCIAL STATEMENTS
AS OF DECEMBER 31, 2000 AND 1999 AND
FOR THE YEAR ENDED DECEMBER 31, 2000

--------------------------------------------------------------------------------

1.       DESCRIPTION OF PLAN

         The following description of the PCS U.S. Employees' Savings Plan (the
         "Plan") provides only general information. Participants should refer to
         the Plan agreement for a more complete description of the Plan's
         provisions.

         General - The Plan is a defined contribution plan sponsored by PCS
         Administration (USA), Inc. (the "Company") covering all employees of
         the Company, PCS Phosphate Company, Inc., PCS Sales (USA), Inc.,
         certain employees of White Springs Agricultural Chemicals, Inc. and
         certain employees of PCS Nitrogen. It is subject to the provisions of
         the Employee Retirement Income Security Act of 1974 ("ERISA").

         Contributions - Participants may contribute up to 20 percent of base
         compensation each year, as defined in the Plan. Participants may also
         contribute amounts representing distributions from other qualified
         defined benefit or contribution plans. The Company matches 100 percent
         of the first five percent of base compensation that participants
         contribute to the Plan. Contributions are subject to certain
         limitations as described in the Plan agreement and the Internal Revenue
         Code.

         Participant Accounts - Individual accounts are maintained for each Plan
         participant. Each participant's account is credited with the
         participant's contribution, the Company's contribution, and allocations
         of plan earnings, and is charged with an allocation of plan losses and
         administrative expenses. Allocations are based on participant earnings
         or account balances, as defined in the Plan. The benefit to which a
         participant is entitled is the benefit that can be provided from the
         participant's vested account.

         Vesting - Participants are immediately vested in their account
         balances.

         Investments - Participants direct the investment of their account
         balances and contributions into various investment options offered by
         the Plan. The Plan currently offers Potash Corporation of Saskatchewan
         Inc. Common Stock, eight mutual funds, and one fixed interest fund as
         investment options for participants. The fixed interest fund is
         comprised of two insurance investment contracts and a pooled investment
         stable value fund which invests in fixed interest insurance investment
         contracts, money market funds, corporate and government bonds,
         mortgage-backed securities, bond funds, and other fixed income
         securities.

                                       4




         Loans to Participants - Participants may borrow from their fund
         accounts up to a maximum amount equal to the lesser of $50,000 or 50
         percent of their vested account balance. Loan terms range from one to
         five years or up to 20 years for the purchase of a primary residence.
         The loans are secured by the balance in the participant's account and
         bear interest at two percentage points above the rate for five-year
         U.S. Treasury Notes. Loans for the purchase of a primary residence bear
         interest at the standard lending rate for 20-year fixed rate home
         mortgage loans. Principal and interest are paid ratably through monthly
         payroll deductions.

         Payment of Benefits - On termination of service, a participant may
         elect to receive either a lump-sum amount equal to the value of the
         participant's vested interest in his or her account, or annual
         installments over the participant's estimated life span. A participant
         may elect to receive payment of benefits prior to termination of
         service, as defined in the Plan. Amounts allocated to accounts of
         participants who have elected to withdraw from the plan but have not
         yet been paid were approximately $-0- and $833,000 at December 31, 2000
         and 1999, respectively.

2.       SUMMARY OF ACCOUNTING POLICIES

         Basis of Accounting - The financial statements of the Plan are prepared
         under the accrual method of accounting.

         Use of Estimates - The preparation of financial statements in
         conformity with accounting principles generally accepted in the United
         States of America requires management to make estimates and assumptions
         that affect the reported amounts of assets, liabilities, and changes
         therein, and disclosure of contingent assets and liabilities. Actual
         results could differ from those estimates. The Plan utilizes various
         investment instruments. Investment securities, in general, are exposed
         to various risks, such as interest rate, credit, and overall market
         volatility. Due to the level of risk associated with certain investment
         securities, it is reasonably possible that changes in the values of
         investment securities will occur in the near term and that such changes
         could materially affect the amounts reported in the statements of net
         assets available for plan benefits.

         Investment Valuation and Income Recognition - The Plan's investment are
         stated at fair value. Shares of registered investment companies are
         valued at quoted market prices which represent the net asset value of
         shares held by the Plan at year-end. The Fixed Interest Fund is valued
         at the amount of participant and Company contributions plus actual
         earnings thereon due to its ability to meet participant investment
         election and participant benefits out of fully benefit responsive
         investments. Such amount approximates fair value. Participants notes
         receivable are valued at cost which approximates fair value. Purchases
         and sales of securities are recorded on a trade-date basis. Interest
         income is recorded on the accrual basis. Dividends are recorded on the
         ex-dividend date.

         Payment of Benefits - Benefits are recorded when paid.

         Expenses - The Plan's administrative expenses are paid by the plan and
         allocated to participants' accounts.

                                       5



3.       INVESTMENTS

         The Plan's investments which represent five percent or more of the
         Plan's net assets available for benefits as of December 31, 2000 and
         1999 are as follows:

                                                         2000         1999

           Fidelity Magellan Fund                     (3,676,670)
           Fidelity Spartan U.S. Equity Index Fund    (1,151,624)
           Fidelity Aggressive Growth Fund           (15,152,256)

                                                  ---------------
                                                     (22,066,942)

4.       INVESTMENT CONTRACT WITH INSURANCE COMPANY

         The Fixed Interest Fund is comprised of two investment contracts and a
         pooled investment stable value fund which invests in fixed interest
         insurance investment contracts, money market funds, corporate and
         government bonds, mortgage-backed securities, bond funds, and other
         fixed income securities. Participants may ordinarily direct the
         withdrawal or transfer of all or a portion of their investment at
         contract value.

         There are no reserves against contract value for credit risk of the
         contract issuer or otherwise. The average yield rates for the years
         ended December 31, 2000 and 1999 were approximately 6.2% and 6.0%,
         respectively. The crediting interest rates as of December 31, 2000 and
         1999 were approximately 5.8% and 5.6%, respectively.

5.       TRANSFERS FROM OTHER PLANS

         Effective January 1, 2000, certain participants in the PCS Nitrogen 401
         (k) Savings Plan (the "PCS Plan"), sponsored by an affiliated company,
         became participants in the Plan. During 2000, participant account
         balances transferred from the PCS Nitrogen Plan were $69,268,889.

                                       6



6.       TRANSFERS TO OTHER PLANS

         Effective February 22, 2000, participants who were active employees of
         MOAB Salt, Inc. became participants in the MOAB Salt, L.L.C.
         Employees' Savings Plan. During 2000, participant account balances
         transferred to the MOAB Salt, L.L.C. Employees' Savings Plan were
         $1,302,349.

7.       RELATED PARTY TRANSACTIONS

         Certain Plan investments are shares of mutual funds managed by Fidelity
         Management Trust Company ("Fidelity"). Fidelity is the trustee as
         defined by the Plan and, therefore, these transactions qualify as
         party-in-interest. Fees paid by the Plan for the investment management
         services were $66,803 for the year ended December 31, 2000.

8.       PLAN TERMINATION

         Although it has not expressed any intent to do so, the Company has the
         right under the Plan to discontinue its contributions at any time and
         to terminate the Plan subject to the provisions of ERISA.

9.       TAX STATUS

         The Plan obtained its latest determination letter dated March 26, 1997,
         in which the Internal Revenue Service stated that the Plan, as then
         designed, was in compliance with the applicable requirements of the
         Internal Revenue Code ("IRC"). The Plan has been amended and restated
         since receiving the determination letter. However, the plan
         administrator and the plan's tax counsel believe that the Plan is
