Mining shall pay to Intrepid Potash, without interest, the amount of the realized benefit promptly following the date it is realized.

The Accountants shall use commercially reasonable efforts to render their written

10

decision specifically establishing the amount(s) of the Potash Post-Closing Income Tax Liability and/or the Potash Post-Closing Non-Income Tax Liability, as applicable, prior to the due date of the applicable Tax Return, but in all events shall render such decision within 30 days after the parties initiate the arbitration proceeding. The fees and other costs of the arbitration and the reasonable attorney fees, expert witness fees, and costs, if any, of Intrepid Mining shall be borne by Intrepid Potash unless the sum of any Potash Post-Closing Income Tax Liability plus any Potash Post-Closing Non-Income Tax Liability asserted by Intrepid Mining with respect to the Mining Post-Closing Return exceeds the sum of such amounts established by the Accountants by at least 20%, in which case, the fees and other costs of the arbitration and the reasonable attorney fees, expert witness fees, and costs, if any, of Intrepid Potash shall be borne by Intrepid Mining. The Accountants’ decision shall include an award of such fees and costs provided by this Section 7.3(a). The decision may be filed in any court of competent jurisdiction and may be enforced by any party as a final judgment of such court. Without the consent of Intrepid Mining and Intrepid Potash, the arbitration shall not determine any issues other than those set forth in this Section 7.3(a); all other disputes shall be handled pursuant to the provisions of Article 8. For purposes of determining any liability of any direct or indirect owner (for Income Tax purposes) of Intrepid Mining for Income Taxes described in clause (i) above, the tax rate applicable to any income or gain allocable to such direct or indirect owner shall be deemed to be the highest rate applicable to an individual with respect to income or gain of such character in the applicable jurisdiction.

(b) All liabilities of Intrepid Mining and any direct or indirect owner (for Income Tax purposes) of Intrepid Mining for Income Taxes that result from or are attributable to the ownership or operation of Exchanged Assets (including the operations of the Subsidiaries) or otherwise with respect to the Assumed Liabilities, to the extent attributable to the portion of any taxable period covered by a Mining Post-Closing Return that begins after the Closing Date, shall constitute Assumed Liabilities from and after the Closing; all liabilities for Taxes other than Income Taxes that result from or are attributable to the ownership or operation of Exchanged Assets (including the operations of the Subsidiaries) or otherwise with respect to the Assumed Liabilities, to the extent attributable to any taxable period covered by a Mining Post-Closing Return, shall constitute Assumed Liabilities from and after the Closing; and, subject to Section 7.1, all other liabilities with respect to Taxes of the type and for the taxable periods covered by Mining Post-Closing Returns shall constitute Retained Liabilities from and after the Closing.

(c) Intrepid Mining shall be entitled to receive, credit and apply in its discretion any refund or overpayment with respect to a taxable period covered by a Mining Post-Closing Return; provided, however, that to the extent that Intrepid Mining actually realizes a benefit from such a refund or overpayment that represents an amount which, if payable as a liability after the Closing, would constitute an Assumed Liability,

11

Intrepid Mining shall pay to Intrepid Potash, without interest, the amount of the realized benefit promptly following the date it is realized.

7.4 Potash Post-Closing Returns.

connection with the defense thereof other than reasonable costs of investigation; provided, however, in the event Intrepid Potash declines or fails to assume the defense of the Proceeding or to employ counsel reasonably satisfactory to the Indemnified Party, in either case within a 30-day period, or if a court of competent jurisdiction determines that Intrepid Potash is not vigorously defending such Proceeding, or if there is a bona fide conflict of interest between Intrepid Potash and the Indemnified Party, then such Indemnified Party may employ counsel to represent or defend it in any such Proceeding and Intrepid Potash shall pay the reasonable fees and disbursements of such counsel or other representative as incurred; provided, further, however, that Intrepid Potash shall not be required to pay the fees and disbursements of more than one counsel for all Indemnified Parties in any jurisdiction in any single Proceeding.

(c) Intrepid Potash will not settle any such Proceeding or consent to the entry of any judgment without the prior written consent of the Indemnified Party, unless such settlement or judgment (i) includes as an unconditional term thereof the giving by the claimant or plaintiff of a release to such Indemnified Party from all liability in respect of such Proceeding and (ii) does not involve the imposition of equitable remedies or the imposition of any obligations on such Indemnified Party and does not otherwise adversely affect such Indemnified Party, other than as a result of the imposition of financial obligations for which such Indemnified Party will be indemnified hereunder. No Indemnified Party will settle any such Proceeding or consent to the entry of any judgment without the prior written consent of Intrepid Potash (such consent not to be unreasonably withheld).
