These forward-looking statements often relate to our future performance and management’s expectations for the future, including statements about our financial outlook. Our forward-looking statements are based on estimates and assumptions that we believe are reasonable. Actual results could be materially different from our forward-looking statements. The factors that could cause actual results to differ are discussed in our periodic filings with the Securities and Exchange Commission. Statements regarding our financial outlook speak only as of the date of our fourth quarter 2013 earnings release, February 12, 2014, and all other forward-looking statements speak only as of the initial release date of this presentation, February 25, 2014. We have no duty to update publicly or revise any forward-looking statements to conform the statements to actual results or to reflect new information or future events. Safe Harbor 2

See the non-GAAP reconciliations set forth later in this presentation for additional information

| Non-GAAP Reconciliations To supplement our consolidated financial statements, which are prepared and presented in accordance with GAAP, we use several non-GAAP financial measures to monitor and evaluate our performance. These non-GAAP financial measures may include adjusted EBITDA, adjusted net income, net sales, average net realized sales price, cash operating costs, average potash gross margin, average net realized sales price advantage, cash margin, and cash margin advantage. These non-GAAP financial measures should not be considered in isolation or as a substitute for, or superior to, the financial information prepared and presented in accordance with GAAP. In addition, because the presentation of these non-GAAP financial measures varies among companies, our non-GAAP financial measures may not be comparable to similarly titled measures used by other companies. We believe these non-GAAP financial measures provide useful information to investors for analysis of our business. We also refer to these non-GAAP financial measures in assessing our performance and when planning, forecasting and analyzing future periods. We believe these non-GAAP financial measures are widely used by professional research analysts and others in the valuation, comparison and investment recommendations of companies in the potash mining industry. Many investors use the published research reports of these professional research analysts and others in making investment decisions. The following slides contain additional information about the non-GAAP financial measures used in this presentation, including reconciliations of our non-GAAP financial measures to the most directly comparable GAAP measures:

| Non-GAAP Reconciliation Calculation of Adjusted EBITDA (in thousands) Adjusted earnings before interest, taxes, depreciation, and amortization (or adjusted EBITDA) is a non-GAAP financial measure that is calculated as net income adjusted for the add back of reductions in the estimated accounts receivable related to the employment-related high wage tax credits in New Mexico, interest expense (including derivatives), income tax expense, depreciation, depletion, and amortization, and asset retirement obligation accretion. We consider adjusted EBITDA to be useful because it reflects our operating performance before the effects of certain non-cash items and other items that we believe are not indicative of our core operations. We use adjusted EBITDA to assess operating performance and as one of the measures under our performance-based compensation programs for employees. 20 Q1 Q2 Q3 Q4 Q1 Q2 Q3 Q4 Net Income $20,626 $19,013 $33,267 $14,537 $14,919 $11,317 $2,026 ($5,987) Add: Allowance for New Mexico employment credits - - - - - - 2,811 - Add: Interest Expense, including realized and 253 215 221 216 213 219 248 851 unrealized derivative gains and/losses Add: Income tax expense 12,613 12,312 10,685 13,874 8,698 7,171 (350) 299 Add: Depreciation, depletion, amortization and accretion 11,256 11,376 12,095 12,872 14,141 14,338 15,561 17,263 Total adjustments 24,122 23,903 23,001 26,962 23,052 21,728 18,270 18,413 Adjusted Earnings Before Income Taxes, Interest Depreciation, Depletion and Amortization $44,748 $42,916 $56,268 $41,499 $37,971 $33,045 $20,296 $12,426 2012 2013

| Non-GAAP Reconciliation Net sales, average net realized sales price, and average net realized sales price advantage are non-GAAP financial measures. Net sales are calculated as sales less freight costs. Average net realized sales price is calculated as net sales, divided by the number of tons sold in the period. Average net realized sales price advantage is calculated by us as the difference between our average net realized sales price and the combined estimated average net realized sales prices of Potash Corporation of Saskatchewan Inc. (POT), The Mosaic Company (MOS), and Agrium Inc. (AGU) based on publicly available information. We consider these measures to be useful because they remove the effect of transportation and delivery costs on sales and pricing. When we arrange transportation and delivery for a customer, we include in revenue and in freight costs the costs associated with transportation and delivery. However, many of our customers arrange for and pay their own transportation and delivery costs, in which case these costs are not included in our revenue and freight costs. We use these measures as key performance indicators to analyze sales and price trends. We also use net sales as one of the measures under our performance-based compensation programs for employees. 21 Net Sales, Average Net Realized Sales Price, and Average Net Realized Sales Price Advantage Average Net Realized Sales Price: Potash: Year Ended December 31, 2005 2006 2007 2008 2009 2010 2011 2012 2013 Sales 150,381 $ 138,482 $ 188,006 $ 362,703 $ 250,887 $ 312,088 $ 392,331 $ 402,382 $ 284,831 $ Freight costs 9,261 8,122 14,271 10,318 13,060 18,021 18,470 21,396 20,796 Net sales 141,120 130,360 173,735 352,385 237,827 294,067 373,861 380,986 264,035 Divided by: Tons sold (in thousands) 869 729 893 724 440 810 793 839 692 Average net realized sales price per ton 162 $ 179 $ 194 $ 486 $ 541 $ 363 $ 472 $ 454 $ 382 $ Estimated average net realized sales price per ton of North American competitors (POT, MOS, AGU) 137 $ 141 $ 152 $ 398 $ 412 $ 403 $ 380 $ 399 $ 309 $ Average net realized sales price advantage 25 $ 38 $ 42 $ 88 $ 129 $ (40) $ 92 $ 55 $ 73 Average net realized sales price advantage expressed as apercentage $ 18% 27% 28% 22% 31% -10% 24% 14% 24%

| Non-GAAP Reconciliation Cash operating costs is a non-GAAP financial measure that is calculated as total of cost of goods sold divided by the number of tons sold in the period and then adjusted to exclude per-ton depreciation, depletion, and royalties. Total cost of goods sold is reported net of by-product credits and does not include warehouse and handling costs. We consider cash operating costs to be useful because it represents our core, per-ton costs to produce potash. We use cash operating costs as an indicator of performance and operating efficiencies and as one of the measures under our performance-based compensation programs for employees. 22 Cash Operating Costs Per Ton Potash: 2013 Cost of goods sold 179,207 $ Divided by sales volume (in thousands of tons) 692 Cost of goods sold per ton 260 $ Less per-ton adjustments Depreciation and depletion 52 Royalties 13 Cash operating costs per ton 195 $
