V. BASIC ENTITLEMENTS, AGGREGATE PRODUCTIVE CAPACITIES, COMMITMENTS AND PURCHASES

5.01 The procedure for establishing the Basic Entitlement of the Producers to supply Potash to Canpotex for export, Grade Pool-by-Grade Pool, for each Fiscal Year and for establishing the quantities of Potash to be purchased from the Producers by Canpotex based on the amount thereof committed to Canpotex by the Producers, shall be as set forth in this Article V, as the same may be adjusted pursuant to this Article V and Articles VI, VII and VIII.

5.02 On or about December 1^st in each and every calendar year, Canpotex management shall submit to the Board of Directors a proposed Operating Plan and Budget for the immediately following Fiscal Year which shall include in writing a total gross sales forecast broken down in tons, Grade-Pool-by-Grade-Pool, and a schedule setting out the resulting Basic Entitlement of each Producer to supply Potash, Grade Pool-by-Grade Pool, for export by Canpotex. Upon approval by the Board of Directors of such proposed Operating Plan and Budget, which approval shall be by majority vote, Canpotex management shall make any necessary revisions in such resulting Basic Entitlements, and shall request a written commitment from each Producer to supply Potash to Canpotex for the Fiscal Year in question in amounts corresponding to each Producer’s respective Basic Entitlement.

5.03 (a) (i) Each Producer, upon receipt from Canpotex management pursuant to section 5.02 of a request for its written commitment, shall be entitled to supply to Canpotex its Basic Entitlement for each Grade Pool of Potash for the coming Fiscal Year in accordance with the approved Operating Plan and Budget and shall inform Canpotex within thirty (30) business days of the amount of Potash, Grade Pool-by-Grade Pool, that it shall commit to supply to Canpotex for export.

(ii) Should any Producer elect not to commit its full Basic Entitlement in respect of any Grade Pool, its Basic Entitlement for subsequent years shall be limited in accordance with the provisions of section 5.06 below, and such Producers as have elected to commit their full Basic Entitlements shall be entitled to supply amounts of Potash in addition to their applicable Basic Entitlements in amounts as calculated under subsection 5.03(a)(iii) in order to make up the shortfall.

(iii) In order to determine final commitments for the supply of Potash to satisfy the requirements of the approved Operating Plan and Budget in the circumstances contemplated by subsection 5.03(a)(ii), such Producers as have offered to commit their full Basic Entitlements may offer to commit additional amounts of Potash to satisfy any shortfall, either in proportion to their respective Basic Entitlements or for any greater amounts up to the

PRODUCER AGREEMENT - EXECUTION COPY Page 13

aggregate amount of any shortfall. If each Producer eligible to offer additional amounts of Potash offers to supply its proportionate share of the shortfall, the shortfall shall be supplied by such Producers in such proportions; and if one or more such Producers elect to commit lesser additional amounts of Potash, the other such Producers may supply the shortfall in proportion to their Basic Entitlements up to the maximum amounts of Potash they have offered to supply.

(b) Nothing in this Agreement is intended to restrict or preclude any Producer from supplying to Canpotex Potash during any Fiscal Year from any Mine, or from any Canadian production source on such terms and conditions as may be applicable to such added source, or to restrict or preclude any Producers from swapping Potash between or among themselves, directly with or without the involvement of Canpotex within their respective Basic Entitlements and commitments to supply any particular Grade Pool to Canpotex.

5.04 Upon completion of the process to determine supply commitments as outlined in section 5.03, each Producer shall execute and deliver to Canpotex effective January 1 in each and every calendar year a Product Supply Agreement with Canpotex in the amounts so determined which shall apply to such Fiscal Year unless further amended as provided herein. In the event of any conflict between the terms and conditions of this Agreement and any Product Supply Agreement, the terms and conditions of this Agreement shall govern.

5.05 On or before July 1 of each Fiscal Year, Canpotex management may prepare a Mid-Year Sales Forecast to cover the period from July 1 through the end of such year, allocated on the same basis as the annual forecast included in the Operating Plan and Budget approved under section 5.02, and showing the amount of Potash which each Producer would be entitled to supply for the balance of the year, Grade Pool-by-Grade Pool, based on the then-applicable calculation of Basic Entitlements as provided under this Article V. The Mid-Year Sales Forecast shall be submitted to the Board of Directors for approval, which approval shall be by majority vote, and upon such approval the following adjustment procedures shall apply:

(i) In the event that the Mid-Year Sales Forecast results in an overall forecast for the current Fiscal Year which is greater than the forecast approved pursuant to section 5.02, each Producer shall have the right to participate in such increased sales on a pro rata Grade Pool-by-Grade Pool basis with all other Producers, following the same procedures as described in section 5.03 (other than subsection 5.03 [a] [ii]) in order to arrive at revised commitments. The revised commitment by each Producer for any such increased sales shall be evidenced by the execution of an amendment to its Product Supply Agreement for such Fiscal Year.

(ii) In the event that the Mid-Year Sales Forecast results in an overall forecast for the current Fiscal Year which is less than that approved pursuant to section 5.02, each Producer shall have its commitment reduced on a pro rata Grade Pool-by-Grade Pool basis with all other Producers for the Fiscal Year in question. The revised commitment of each Producer for any such

PRODUCER AGREEMENT - EXECUTION COPY Page 14

reduction shall be communicated by Canpotex management by fax, e-mail or like means and shall be confirmed by fax, e-mail or like means forthwith thereafter, and such reduction shall be deemed to amend such Producer’s applicable Product Supply Agreement and to be effectively completed if done as aforesaid without further formality.

5.06 In the event a Producer elects, in connection with the commitment process with respect to the Fiscal Year Operating Plan and Budget outlined under sections 5.02 and 5.03, not to commit to Canpotex its entire Basic Entitlement of the forecast total sales of Canpotex for each Grade Pool (the year in which such election not to fully commit occurs being hereinafter referred to as the “Base Commitment Year”), such Producer’s Basic Entitlement for the subsequent two years following such Base Commitment Year shall be limited as follows:

(a) For the first Fiscal Year following the Base Commitment Year, such Producer’s Basic Entitlement shall be limited to the amount it committed to supply for the Base Commitment Year, plus one third (1/3) of the difference between (i) the amount of its Basic Entitlement for the Base Commitment Year and (ii) the amount it elected to commit for the Base Commitment Year.

(b) For the second Fiscal Year following the Base Commitment Year, such Producer’s Basic Entitlement shall be limited to the amount it committed to supply for the Base Commitment year, plus two thirds (2/3) of the difference between (i) the amount of its Basic Entitlement for the Base Commitment Year and (ii) the amount it elected to commit for the Base Commitment Year.

(c) In the event that the sales forecast of Canpotex, either as provided under section 5.02 for any Fiscal Year following a Base Commitment Year or as revised under section 5.05, increases above or decreases below the actual sales of Canpotex for the Base Commitment Year, then the Basic Entitlement, determined in accordance with the formula set forth in this section 5.06, shall be increased or decreased at such time on a pro rata, Grade Pool-by-Grade Pool, basis, having regard to such changed forecast sales of Canpotex.

(d) During the first and second Fiscal Years following the Base Commitment Year, each Producer whose Basic Entitlement is not subject to the limitations provided in section 5.06 (a) or (b), shall have the right, but not the obligation, to supply its proportionate share of the amount of Potash by which the Basic Entitlement was reduced as provided herein for any Producer which elected not to supply its full Basic Entitlement. The calculation of such additional amount for each Producer having the right to apply an additional amount under this subsection 5.06 (d) shall follow the same principles and procedures as set forth in subsection 5.03 (a)(iii).

(e) The adjustments provided for in this section 5.06 (i) shall be subject to all of the other provisions set forth in this Article V in respect of the entitlement/commitment procedure for Producers to supply Potash to Canpotex; (ii) shall be applicable to all Grade Pools on a proportionate basis; (iii) shall be applied cumulatively in the event that during any period of limited commitment set forth in section 5.06(a) or section 5.06 (b) a Producer elects to further reduce

PRODUCER AGREEMENT - EXECUTION COPY Page 15

its commitment as permitted under this Agreement; and (iv) shall be subject to such further adjustments as may be required to reflect a change in a Producer’s Aggregate Productive Capacity pursuant to Articles VI, VII or VIII.

(f) Notwithstanding the foregoing, the adjustments provided for in this section 5.06 shall not apply to any Producer in the event such Producer fails to commit or supply all or any portion of its Basic Entitlement, Grade Pool-by-Grade Pool, to Canpotex (i) as a result of circumstances occurring beyond its reasonable control as provided in Article XVII; (ii) as a result of a Disaster, as provided in Article VIII; or (iii) if such failure is consented to by the Board of Directors by unanimous resolution, or as may be permitted by or pursuant to any applicable Product Supply Agreement.

5.07 There shall be no adjustments to Basic Entitlement (whether under section 5.06 or otherwise) in the event a Producer elects in connection with the commitment process set forth in section 5.05 in respect of Mid-Year Sales Forecasts not to commit its full proportionate share of any increased amount of Potash required by such forecast.

5.08 The forecasts provided in this Article V are for purposes of estimating Canpotex requirements and determining Basic Entitlements. However, timing of forecasts may vary depending upon market conditions or other factors. Accordingly, the Board of Directors may, by unanimous vote: (a) alter or amend the time periods set forth in this Article V, (b) approve or authorize further adjustments to sales forecasts and commitments following such procedures as the Board of Directors may authorize and determine (but without causing any adjustment under section 5.06 or otherwise in a Producer’s Basic Entitlement), or (c) permit any Producer by mutual written agreement with Canpotex to vary its commitment during any Fiscal Year under such terms and conditions as it may determine. Additionally, it is recognized that a decrease in market demand or other factors beyond Canpotex’s control may on occasion result in Canpotex being only able to purchase less than the full commitments of each Producer as previously confirmed by Product Supply Agreements, in which case each Producer shall have its commitment reduced on a pro rata Grade Pool-by-Grade Pool basis with all other Producers for the Fiscal Year in question.

5.09 (a) In the event that a Producer sells or otherwise in any way transfers part of its Assets which sale or transfer relates or pertains in any measurable way to and which reduces the production capacity of such Producer to produce Potash, the Aggregate Productive Capacity of such Producer shall be reduced on a proportionate basis to reflect such sale or transfer. In the event that at the time of such sale or transfer the Basic Entitlement of such Producer is subject to any limitation(s) applicable pursuant to section 5.06, such limitations shall continue to apply, but shall be subject to adjustment on a proportionate basis. The Individual Productive Capacity(ies) of any Mine or Mines subject to such sale or transfer shall be similarly adjusted to reflect such sale or transfer.

(b) Any Producer acquiring Assets in a transaction subject to section 5.09 (a) shall be deemed to have its Aggregate Productive Capacity increased by an amount equal to the reduction in Aggregate Productive Capacity of the selling Producer effected pursuant to such section, and shall be subject to a further limitation to its resulting Basic Entitlement in the amount of any proportionate adjustment to section 5.06 limitations applicable to the

PRODUCER AGREEMENT - EXECUTION COPY Page 16

selling Producer made under section 5.09(a), it being the intention that in such case the net adjustment in Basic Entitlements of the Producer selling or transferring such Assets shall be fully and equally offset by the net adjustment in Basic Entitlements of the Producer acquiring such Assets. The Individual Productive Capacity(ies) of any Mine or Mines subject to such sale or transfer shall be similarly adjusted to reflect such sale or transfer.

(c) Any sale or transfer described in this section 5.09 shall not change or affect or reduce any commitment made prior to such sale or transfer by the Producer making such sale or transfer to supply Potash to Canpotex, provided, however, that if Assets are sold and transferred to another Producer, the parties to said transaction may agree between themselves to a transfer of responsibilities with respect to such commitments in whole or in part, subject to the consent of Canpotex which consent shall not unreasonably be withheld.

(d) Notwithstanding anything else to the contrary, nothing herein is intended to nor shall it restrict a Producer from selling and each Producer shall be entitled as of right to sell, Potash or Assets to any present or future affiliate, associate or subsidiary owned or controlled, directly or indirectly, whether through the ownership of shares or assets or through contract or debt, or otherwise, in any manner whatsoever, whether in law or in equity, of such Producer regardless of the capacity to produce Potash from any source of such Producer and its present and future affiliates, associates, subsidiaries, taken individually or together in any combination on the basis that such Producer and its present and future affiliates, associates, subsidiaries, taken individually or together in any combination shall be treated as one entity for all purposes hereunder.

VI. MAJOR EXPANSIONS

6.01 Any Producer which intends to undertake a Major Expansion shall give a Notice of Expansion to Canpotex and contemporaneously to the other Producers to that effect, with such notice to be given in strict compliance with the timing provisions of section 1.01(z) and not to provide any further information than the fact that such Major Expansion is to commence, that such Producer believes it complies with the definitional requirements of Section1.01(s), and that such Notice is being given solely for purposes of invoking the provisions of this Article VI.

6.02 Following the delivery of a Notice of Expansion, the Producer undertaking such Major Expansion shall, as soon as reasonably practicable thereafter, supply the necessary Operating Results to the Canpotex Auditors to enable the Canpotex Auditors to verify the Pre-Expansion Audit Amount.

6.03 Following the delivery of a Notice of Expansion, the applicable Producer may, by notice to Canpotex and contemporaneously to the other Producers, at any time voluntarily revoke the Notice of Expansion.

6.04 Following completion of a Major Expansion, the applicable Producer shall, as soon as reasonably practicable thereafter, supply to the Canpotex Auditors:

(a) the necessary Operating Results; and

PRODUCER AGREEMENT - EXECUTION COPY Page 17

(b) the necessary Dedicated Capital Documentation;

to enable the Canpotex Auditors to verify the Post-Expansion Audit Amount.

6.05 The Pre-Expansion Audit Amount verification and the Post-Expansion Audit Amount verification by the Canpotex Auditors shall be delivered to Canpotex and the Producers as soon as reasonably practicable after completion of each.

6.06 If, for the sole purpose of determining the Producer’s Basic Entitlement, the increase in the Producer’s Aggregate Productive Capacity and Individual Productive Capacity as a result of the Major Expansion has been verified by the Canpotex Auditors in compliance with this Article VI, and such verification by the Canpotex Auditors has been accepted in writing by all Producers, which acceptance shall not be unreasonably withheld, the Aggregate Productive Capacity of the applicable Producer shall thereafter be increased by the amount of the Productive Capacity Change and the Individual Productive Capacity of the applicable Mine shall be increased so that it equals the Post-Expansion Audit Amount for the applicable Mine. Such increases shall be effective from and after:

(a) January 1 in the immediately following Fiscal Year, provided such Major Expansion has been fully completed and verified on or before December 31 in any year; or

(b) July 1 in any Fiscal Year, provided such Major Expansion has been fully completed and verified on or before June 30 in such Fiscal Year.

6.07 If the Post-Expansion Audit Amount is greater than the Individual Productive Capacity of the Mine, but such expansion does not qualify as a Major Expansion, the Individual Productive Capacity of the Mine shall still be increased so that it equals the Post-Expansion Audit Amount for the applicable Mine, with such increase being effective at the time indicated in section 6.06 above.

6.08 If the Major Expansion relates to a Solution Mine, then the level of accumulated crystal Potash product (the “Measured Level of Product”) in all crystallization ponds of the Solution Mine shall be measured both within five Operating Days before and within five Operating Days after the demonstration period of 90 Operating Days used for purposes of calculating the applicable Post-Expansion Audit Amount. If the aggregate Measured Level of Product in the ponds is less following the demonstration period than it was prior to the demonstration period, then the Post-Expansion Audit Amount shall be reduced by an amount of Product Tonnes calculated pursuant to the following formula:

R = A(B)

Where:

R equals the number of Product Tonnes by which the Post-Expansion Audit Amount shall be reduced;

A equals the difference in the Measured Levels of Product, expressed in metric tonnes of crystal product; and

PRODUCER AGREEMENT - EXECUTION COPY Page 18

B equals a conversion factor of 85%.

6.09 Notwithstanding any provision of this or any predecessor Producer Agreements to the contrary, the provisions set forth in this Article VI shall be effective with respect to any Major Expansion for which a Notice of Expansion has been given and neither revoked nor deemed revoked and for which a Post-Expansion Audit Amount has not been determined on or before the Effective Date, except that for all Major Expansions for which a Notice of Expansion has been given and neither revoked nor deemed revoked and for which a Post-Expansion Audit Amount has not been determined before the Effective Date, Dedicated Capital shall be not less than US$ 25,000,000. In addition, it is acknowledged and agreed that the Notice of Expansion given by Mosaic Potash Esterhazy Limited Partnership prior to the Effective Date in respect of its K₃ mine project relates to a proposed Major Expansion of the Mosaic Esterhazy (K₁ and K₂) Mine.

6.10 If any Mine is permanently closed at the end of its production life, such Mine shall be deleted from the listing of Individual Productive Capacities and the Board shall by unanimous vote determine an appropriate adjustment to the Aggregate Productive Capacity of the Producer owning such Mine.

VII. NEW MINE CONSTRUCTION

7.01 In the event any Producer undertakes and completes the construction of a New Mine, the applicable Producer shall, as soon as reasonably practicable thereafter, supply to the Canpotex Auditors the necessary Operating Results to enable the Canpotex Auditors to verify the Post-New Mine Construction Audit Amount.

7.02 The Post-New Mine Construction Audit Amount verification by the Canpotex Auditors shall be delivered to Canpotex and the Producers as soon as reasonably practicable after completion thereof.

7.03 If a New Mine Construction has been verified by the Canpotex Auditors, in compliance with this Article VII, and provided that, for the sole purpose of determining the Producer’s Basic Entitlement, the increase in the Producer’s Aggregate Productive Capacity, as a result of the New Mine Construction has been verified by the Canpotex Auditors in compliance with this Article VII, and such verification by the Canpotex Auditors has been accepted in writing by all Producers, which acceptance shall not be unreasonably withheld, each of the Aggregate Productive Capacity of the applicable Producer and the Individual Productive Capacity of the New Mine shall thereafter be increased by the amount of the Productive Capacity Change effective from and after:

(a) January 1 in the immediately following fiscal year, provided such New Mine Construction has been fully completed and verified on or before December 31 in any year; or

(b) July 1 in any fiscal year provided such New Mine Construction has been fully completed and verified on or before June 30 in such fiscal year.

PRODUCER AGREEMENT - EXECUTION COPY Page 19

VIII. DISASTERS

8.01 (a) If, after the Effective Date an event or series of related events occurs that the Affected Producer reasonably believes has or have caused a Disaster at a Mine, the Affected Producer shall, as soon as practicable, give notice of such event(s) (an “Owner Disaster Notice”) to the other Producers and contemporaneously to Canpotex. It is acknowledged that if such an event or series of related events occurs but no Owner Disaster Notice is given, any of the other Producers that reasonably believe such event(s) has or have caused a Disaster shall be entitled to give notice of such event(s) (a “Non-Owner Disaster Notice”) simultaneously to Canpotex, the Affected Producer and all other Producers.

(b) If either an Owner Disaster Notice or a Non-Owner Disaster Notice is given, an audit shall be completed to determine the Pre-Disaster Audit Amount, and the Affected Producer shall, as soon as reasonably practicable, and in any event within six months following the date any such Notice is given, supply the necessary Operating Results to the Canpotex Auditors to enable the Canpotex Auditors to verify the Pre-Disaster Audit Amount. The Pre-Disaster Audit Amount verification shall be delivered to Canpotex and the Producers as soon as reasonably practicable thereafter.

(c) If either an Owner Disaster Notice or a Non-Owner Disaster Notice is given the Affected Producer shall, as soon as reasonably practicable and in any event within one year following the date that any such Notice is given, supply the necessary Operating Results to the Canpotex Auditors to enable the Canpotex Auditors to verify the Post-Disaster Audit Amount. The Post-Disaster Audit Amount verification shall be delivered to Canpotex and the Producers as soon as reasonably practicable thereafter.

(d) The Pre-Disaster Audit Amount and the Post-Disaster Audit Amount shall be used to confirm whether or not a Disaster has in fact occurred at the Mine.

(e) Each Producer represents to Canpotex that as of the Effective Date and the date of signing this Agreement it is not aware of, the occurrence of any event or series of related events at any of its Mines that has or have caused a Disaster at any such Mines.

8.02 If after the Effective Date a Disaster occurs, the Aggregate Productive Capacity of the Affected Producer and the Individual Productive Capacity of the applicable Mine of the Affected Producer shall not be reduced as provided for in section 8.06 hereof provided that each of the following events occur:

(a) on or prior to the 30th day preceding the end of the Suspension Period, the Affected Producer submits a Plan to Canpotex and the other Producers that is reasonably likely to achieve the results specified therein; and

(b) the Affected Producer fully implements or causes to be implemented the Plan before the expiration of the Additional Suspension Period and such implementation achieves the results specified in the Plan.

PRODUCER AGREEMENT - EXECUTION COPY Page 20

8.03 Following full implementation of the Plan, the Affected Producer shall, as soon as reasonably practicable thereafter, supply the necessary Operating Results to the Canpotex Auditors to enable the Canpotex Auditors to verify the Post-Plan Audit Amount. The Post-Plan Audit Amount verification shall be delivered to Canpotex and the Producers as soon as reasonably practicable thereafter.

8.04 If a Plan has been fully completed and verified in compliance with this Article VIII, the Aggregate Productive Capacity of the Affected Producer shall thereafter be the Aggregate Productive Capacity of the Affected Producer immediately before the Disaster:

(a) minus the Pre-Disaster Audit Amount; and

(b) plus the Post-Plan Audit Amount;

provided that the Aggregate Productive Capacity of the Affected Producer calculated as aforesaid shall not be increased above the Aggregate Productive Capacity of the Affected Producer immediately before the Disaster, unless such increase shall be at least 200,000 Product Tonnes and, for purposes of determining the Affected Producer’s Basic Entitlement, the increase in such Aggregate Productive Capacity has been verified by the Canpotex Auditors in compliance with this Article VIII, and such verification has been accepted in writing by all Producers, which acceptance shall not be unreasonably withheld.

8.05 If a Plan has been fully completed and verified in compliance with this Article VIII, the Individual Productive Capacity of the applicable Mine shall be adjusted as follows:

(a) if the Post-Plan Audit Amount is greater than the Individual Productive Capacity of the Mine, then the Individual Productive Capacity of the Mine shall be increased so that it equals such Post-Plan Audit Amount; or

(b) if the Post-Plan Audit Amount is not greater than the Individual Productive Capacity of the Mine, then the Individual Productive Capacity of the Mine shall thereafter be the Individual Productive Capacity of the Mine immediately before the Disaster:

(i) minus the Pre-Disaster Audit Amount; and

(ii) plus the Post-Plan Audit Amount.

8.06 If a Disaster occurs and any of the events specified in section 8.02 hereof do not occur within the time frame set forth therein, then unless otherwise agreed by all Producers, the Aggregate Productive Capacity of the Affected Producer and the Individual Productive Capacity of the applicable Mine of the Affected Producer shall be reduced by an amount equal to the difference between the Pre-Disaster Audit Amount and the Post-Disaster Audit Amount.

8.07 If a Disaster relates to a Solution Mine, then the Measured Level of Product in all crystallization ponds of the Solution Mine shall be measured both within five Operating Days before and within five Operating Days after the demonstration period of 90

PRODUCER AGREEMENT - EXECUTION COPY Page 21

Operating Days used for purposes of calculating the applicable Post-Disaster Audit Amount. If the aggregate Measured Level of Product in the ponds is less following the demonstration period than it was prior to the demonstration period, then the Post-Disaster Audit Amount shall be reduced by an amount of Product Tonnes calculated pursuant to the following formula:

R = A(B)

Where:

R equals the number of Product Tonnes by which the Post-Disaster Audit Amount shall be reduced;

A equals the difference in the Measured Levels of Product, expressed in metric tonnes of crystal product; and

B equals a conversion factor of 85%.

8.08 If a Disaster relates to a Solution Mine, then the Measured Level of Product in all crystallization ponds of the Solution Mine shall be measured both within five Operating Days before and within five Operating Days after the demonstration period of 90 Operating Days used for purposes of calculating the applicable Post-Plan Audit Amount. If the aggregate Measured Level of Product in the ponds is less following the demonstration period than it was prior to the demonstration period, then the Post-Plan Audit Amount shall be reduced by an amount of Product Tonnes calculated pursuant to the following formula:

R = A(B)

Where:

R equals the number of Product Tonnes by which the Post-Plan Audit Amount shall be reduced;

A equals the difference in the Measured Levels of Product, expressed in metric tonnes of crystal product; and

B equals a conversion factor of 85%.

IX. NOT TO AFFECT SALES IN CANADA OR UNITED STATES

9.01 This Agreement relates only to the export of Potash from Canada of Potash produced by each Producer in Canada for sale by Canpotex to purchasers for ultimate delivery to any destination outside Canada and the United States, and no provision of this Agreement shall be deemed to relate to any business of the Producer except the export of Potash from Canada, within the provisions of subsections 45(5) and 90.1(8) of the Competition Act, R.S.C. 1985, c. C-34, as amended, or as the same may be further amended, repealed, replaced or re-enacted from time to time.

PRODUCER AGREEMENT - EXECUTION COPY Page 22

9.02 Nothing contained herein shall restrict or be deemed to affect in any way the freedom of each Producer to engage in the production of Potash in such quantities and at such times as the Producer individually and independently may determine or to engage in the sale of Potash to any purchaser or purchasers for ultimate delivery to any destination in Canada or the United States without regard to Canpotex or any other Producer. The quantities of Potash which any Producer shall sell from time to time to purchasers for ultimate delivery to any destination in Canada or the United States and the prices and terms upon which Potash shall be sold to any such purchasers shall be determined individually and independently by each Producer without regard to the provisions of this Agreement or any Product Supply Agreement and without restriction by or consultation with Canpotex or any other Producer.

9.03 Canpotex shall not sell or contract for the sale of any Potash to purchasers for ultimate delivery to any destination in Canada or the United States.

X. DELIVERY AND TERMS OF SALE

10.01 All quantities of Potash constituting the portion of each Producer’s commitment accepted by Canpotex under the terms of this Agreement shall be made available to Canpotex in accordance with the terms of the Product Supply Agreement. Shipments of Potash shall be scheduled for supply by the Producer from time to time by Canpotex in accordance with the authority of the Board of Directors subject to the terms of this Agreement and such Product Supply Agreements, with title and risk of loss in respect of such Potash transferring unto and vesting with Canpotex when loaded free on board a common carrier at the Mine. Canpotex shall without formality be deemed to have purchased the quantities of Potash set out in commitments communicated to or made part of Product Supply Agreements as and when title to such Potash passes to Canpotex.

10.02 Unless different terms are agreed upon between Canpotex and a particular Producer with respect to any specific order, all contracts for the purchase and sale of Potash referred to under the provisions of section 10.01 shall be filled by the Producer by shipping for the account of Canpotex in accordance with the terms of the order. Canpotex shall prepare or obtain invoices, consular documents and other papers relating to the shipment, and shall arrange for shipment on appropriate forms of charter parties, contracts of affreightment or other suitable arrangements, and for cargo marine insurance, if any, on appropriate forms in the name of and payable to Canpotex, and shall make payment of freight and insurance premiums when due, if applicable.

10.03 Canpotex and each Producer may enter into further agreements supplemental to, and consistent with, this Agreement to provide for procedure for transmission of orders, delivery and shipment and matters related thereto.

XI. ACCOUNTING FOR SALES, PURCHASES AND EXPENSES OF CANPOTEX AND PAYMENT FOR POTASH

11.01 The Board of Directors shall determine the prices and terms of sale of all Potash which may be sold by Canpotex. It may from time to time delegate authority to make such determination to a committee of the Board of Directors, or to the President of Canpotex.

PRODUCER AGREEMENT - EXECUTION COPY Page 23

11.02 Canpotex, in entering into contracts for the export of Potash as contemplated herein, shall at all times adhere to and comply with any and all applicable laws, by-laws, orders, ordinances and regulations, all to the intent that the resulting contracts shall not violate or infringe any of the foregoing which are, from time to time, in force and effect.

11.03 The purchase price per ton finally payable by Canpotex to each Producer for Potash purchased in each Fiscal Year, shall be calculated in tons of K₂O equivalent and shall be determined for each Grade Pool of Potash in the following manner:

(a) For the purpose of establishing working capital to finance its operations hereunder Canpotex shall from time to time hold back from the distribution of sales proceeds as hereinafter described such amounts as are, in the opinion of management, reasonably necessary for expenses incurred in connection with its operations including, but not limited to, inventory, receivables, interest and financing, employee and associated expenses, marketing expenses, distribution and logistics expenses, facilities and supplies, management agreements, agency expenses and commissions, and generally expenses incurred by Canpotex in the conduct of its operations as approved by the Board of Directors acting unanimously (such expenses collectively referred to as “Expenses”). All such withholdings shall be on a proportionate basis, as among the Producers, such that each Producer’s share of such withholdings is in the same percentage relationship as the Producer’s share of sales proceeds of Canpotex bears to the gross sales of Canpotex in the Fiscal Year in question. Canpotex shall provide a report on an estimated basis for each quarterly period (or such other periods during the Year as management may determine) and shall adjust the amount of the holdback at the end of each reporting period and at the end of the Fiscal Year so as to assure that on a rolling basis and at the end of the Fiscal Year each Producer has borne the cost of operations of Canpotex proportionate to the amount that the sales proceeds received by Canpotex from the sale of Potash supplied by the Producer in question bears to the gross sales of Canpotex during the said Fiscal Year.

(b) Canpotex shall pay out to each Producer from time to time but not less frequently than quarterly the balance of sales proceeds realized from the sale by Canpotex of the Potash supplied by the Producer hereunder after deducting the holdback pursuant to subsection (a) above. The distribution under this subsection (b) shall be on an estimated basis and shall be adjusted at the end of each quarterly period and at the end of the Fiscal Year in question.

(c) The proceeds of sales received by Canpotex shall, subject to the holdback as in section 11.03 (a) provided, be divided amongst each Producer on the basis of its respective proportion of the total tonnage of Potash Grade Pool-by-Grade Pool sold by all Producers to Canpotex in the Fiscal Year in question; such division shall be conducted on an annualized basis notwithstanding any mid-year change in any Basic Entitlement. Distribution of sales proceeds shall therefore be carried out not less frequently than quarterly on an estimated basis with a final adjustment not later than 120 days after the end of each Fiscal Year. For this purpose all sales shall be pooled Grade Pool-by-Grade Pool and all Potash supplied by all Producers shall form the pool.

PRODUCER AGREEMENT - EXECUTION COPY Page 24

(d) In making interim payments for Potash purchased by Canpotex from Producers, Canpotex may make such interim payments as are authorized in this section 11.03 to Producers.

(e) For greater certainty and notwithstanding anything else to the contrary herein contained, the purchase price per ton finally payable by Canpotex to each Producer for each Grade Pool of Potash purchased from each Producer in each Fiscal Year by Canpotex shall be based on the actual Grade Pool of Potash supplied by each Producer without regard to the Grade Pool description for that Potash in sales made by Canpotex and for this purpose, all purchases from each Producer by Canpotex shall be pooled Grade Pool-by-Grade Pool and all Potash supplied by all Producers for each Grade Pool shall form the pool.

11.04 At the end of each Fiscal Year, after all the adjustments provided for in this Article XI have been made, Canpotex shall prepare a statement for each Producer in such form as may be approved by the Board of Directors which shall give to the Producer full disclosure of the transactions reflected in the accounts of the Producer. From time to time during the Fiscal Year Canpotex shall furnish such reports to each Producer as to the operations of Canpotex as may be determined by the Board of Directors.

11.05 In the event that Canpotex shall not receive payment for any Potash sold hereunder and in the event that, in the opinion of the President the amount receivable or any part thereof should be written off as a bad debt of Canpotex, such amount so written off shall be treated as a sales expense of Canpotex during the Fiscal Year of such write off.

11.06 As provided for in this Article XI it is intended that all Expenses of Canpotex approved by the Board of Directors in the manner required shall be met from the proceeds of sales of Canpotex in each Fiscal Year.

XII. BOOKS AND AUDIT

12.01 The accounts, books and records of Canpotex shall be audited annually by the independent firm of chartered accountants from time to time appointed as the Canpotex Auditors and an annual statement as to the transactions of Canpotex and the amounts payable to all Producers as reported upon by the Canpotex Auditors shall be submitted to each Producer. If a Producer does not make objection to such annual statement on or before the time it is submitted to and accepted by the Canpotex Board of Directors, such statement shall be deemed to be final, conclusive and binding on such Producer.

XIII. MARKETING, TRANSPORTATION AND LOGISTICAL HANDLING BY CANPOTEX

13.01 Canpotex shall have full authority to select and appoint selling representatives and distributors for the purpose of sale for export by Canpotex hereunder. Such representatives and distributors shall be paid such commission or other fees as may be agreed upon between them and Canpotex in writing and the decision of the Board of Directors on all such matters shall be conclusive and binding upon each Producer.

PRODUCER AGREEMENT - EXECUTION COPY Page 25

13.02 Canpotex shall have full authority to enter into appropriate arrangements for the transportation and logistical handling of potash supplied to it for sale for export by Canpotex hereunder, subject to such review by the Board of Directors as may be required in respect of major expenditures or commitments, and the decision of the Board of Directors on all such matters shall be conclusive and binding upon each Producer.

XIV. BOARD OF DIRECTORS

14.01 The Board of Directors shall have full authority to make such provision for the conduct of the business of Canpotex as the Board of Directors considers to be to the advantage of Canpotex and the Producers, including the determination of prices to be received or paid for Potash for export and the terms and conditions on which it may be sold, which authority may be delegated to the President of Canpotex or such other officers or management of Canpotex from time to time or in such manner as the Board of Directors may determine.

14.02 With respect to matters not specifically provided for herein the Board of Directors may make such regulations and adopt such policies, not inconsistent with the provisions of this Agreement, for the purpose of carrying into effect the provisions of this Agreement, as the Board of Directors in its discretion may determine and such regulations and policies shall be binding upon all Producers.

XV. ARBITRATION

15.01 All disputes arising out of or in connection with this Agreement, or in respect of any legal relationship associated with or derived from this Agreement, shall be finally resolved by arbitration pursuant to the National Arbitration Rules (the “Rules”) of the ADR Institute of Canada, Inc. (the “Institute”). The place of arbitration shall be Saskatoon, Saskatchewan. The language of the arbitration shall be English.

15.02 Every such dispute arising shall be referred to an Arbitration Panel (“Panel”) of three arbitrators, one to be appointed by each of the two parties to the arbitration (and a group of parties having a common interest shall be treated as being one party for the purpose hereof) and the two arbitrators so appointed shall appoint the third arbitrator. The Panel chair shall be selected by the Panel. Should the appointed arbitrators fail to agree on the appointment of a third arbitrator within the 15 day period following the date on which the last Panel member has been appointed, any party to the arbitration may apply to the Institute to make the required appointment. Should the parties in a group of parties having a common interest fail to agree to their choice of an arbitrator to represent such group within the 15 day period following the date on which the first Panel member has been appointed, any party to the arbitration may apply to the Institute to make the required appointment for such group.

15.03 In any case involving a dispute between more than two parties to this Agreement (and a group of parties having a common interest shall be treated as being one party for the purpose hereof) shall be referred to a Panel of three arbitrators, each of whom shall be appointed by the Institute. Such appointments by the Institute shall be in accordance with the procedures specified in Rule 15, provided that any list delivered by the Institute to the parties shall contain not less than 9 names.

PRODUCER AGREEMENT - EXECUTION COPY Page 26

15.04 The arbitration shall be conducted upon the terms and conditions as may be prescribed by the arbitrators who shall not be bound by the rules of evidence nor by The Arbitration Act, 1992 of Saskatchewan and the arbitrators shall be free to consider any evidence deemed to be relevant. The decision of the arbitrators shall not be subject to appeal, or subject to judicial review by Writ of Certiorari or otherwise, or subject to review or appeal by any other process by any tribunal whatsoever. The parties to such arbitration shall share equally the cost of the arbitrators and shall bear their own expenses incurred in such arbitration proceedings.

XVI. CONFIDENTIALITY
