| | (iii) | any other engineering firm that could reasonably be considered, after having made reasonable inquiry, as having a potential conflict of interest, including lacking sufficient independence to carry out the Engineering
Audit in an unbiased manner based on the engineering firms professional judgment (provided, however, that no such conflict of interest shall be deemed to exist solely because such firm was involved in the Major Expansion in a lesser capacity
than the Design Engineers or EPCM Contractor).

unreasonably withheld,

such proposed revised Aggregate Productive Capacity of the applicable Producer shall become that Producers Aggregate
Productive Capacity and such proposed revised Individual Productive Capacity of the applicable Mine shall become the Individual Productive Capacity for that Mine. Such increases shall be effective from and after:



| | (a) | January 1 in the immediately following Fiscal Year, provided the Engineering Audit Completion Date occurs on or before December 31 in any year; or

|6.17 | Notwithstanding Section 6.16, in the event a consultation process conducted in accordance with Section 6.15(h) identifies issues which cannot be resolved within ten (10) business days from the date the
consultation takes place (the Consultation Completion Deadline), the parties hereto shall confer to determine whether the results of the Engineering Audit should be provisionally accepted pending ultimate resolution, or held in abeyance
pending such resolution, considering the materiality of the issue, the magnitude of the adjustment and the anticipated time required to resolve the issues. If the parties hereto cannot reach resolution of these matters, the Expanding Producer,
regardless of whether the Expanding Producer previously confirmed (or was deemed to confirm) to Canpotex that it accepted the results of the Engineering Audit Report, may elect to apply the Production Run Procedures (in which case, the Expanding
Producer shall be considered an Electing Producer) or, if no such election is made, all questions shall immediately proceed to binding arbitration and resolved no later than one (1) month from the Consultation Completion Deadline with
retroactive effect to the date that would otherwise apply pursuant to Section 6.16 (being January 1 or July 1, as applicable). If the Expanding Producer is not satisfied with the results of such arbitration, the Expanding Producer,

this Part V applies, the results of any Engineering Audit applicable to the Major Expansion shall not be used to determine, as a result of such Major Expansion, the Productive Capacity Change, the Producers Aggregate Productive Capacity or the
Individual Productive Capacity of the applicable Mine, but rather, such matters shall be determined in accordance with this Part V.
|---- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|6.19 | (a) | Where this Part V applies, the Producer undertaking the Major Expansion shall, as soon as reasonably practicable, supply to the Canpotex Auditors:

parties to this Agreement in connection with the Production Run Completion Notice set forth in Section 6.21. Following verification by the Canpotex Auditors of the Post-Expansion Audit Amount and Canpotexs receipt of the Production Run
Post-Expansion Consent, the applicable Mine expansion in question shall be deemed, for the purposes of this Agreement, to (a) constitute a Major Expansion and (b) have been fully completed by the date of the Post-Expansion Audit Amount
verification received from the Canpotex Auditors.

Audit Amount, the Post-Expansion Audit Amount and the existing Individual Productive Capacity of the applicable Mine (in each case, with respect to the Major Expansion), whether the Major Expansion has resulted in a Productive Capacity Change. If
Canpotex so determines that there has been a Productive Capacity Change, Canpotex shall, within five (5) business days of receiving verification of the Post-Expansion Audit Amount from the Canpotex Auditors, notify the Producers in writing of
the proposed revised Aggregate Productive Capacity and Individual Productive Capacity of the applicable Producer and Mine, respectively, (a Production Run Completion Notice) whereby:

Canpotex and the Producers agree that the Production Run Post-Expansion Consent shall be in such form as is agreed to by Canpotex and the Producers from
time to time, each acting reasonably.



|6.22 | 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

B equals a conversion factor of 85%.
