&lt;p style="FONT-FAMILY: times"&gt;&lt;font size="2"&gt;&lt;b&gt;Note&amp;nbsp;18&amp;#151;RELATED PARTIES&lt;/b&gt;&lt;/font&gt;&lt;/p&gt;
&lt;p style="FONT-FAMILY: times"&gt;&lt;font size="2"&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;The members of Mining were Intrepid Production Corp. ("IPC"), whose sole shareholder is Robert P. Jornayvaz III ("Mr.&amp;nbsp;Jornayvaz"), Harvey Operating and Production Company ("HOPCO"), whose sole shareholder is Hugh E. Harvey, Jr. ("Mr.&amp;nbsp;Harvey"), and Potash Acquisition,&amp;nbsp;LLC ("PAL"), controlled by Platte River Ventures Investors I,&amp;nbsp;LLC. These members maintained a controlling interest in Intrepid immediately subsequent to the IPO. &lt;/font&gt;&lt;/p&gt;
&lt;p style="FONT-FAMILY: times"&gt;&lt;font size="2"&gt;&lt;b&gt;&lt;i&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;Airplane Use Policy&lt;/i&gt;&lt;/b&gt;&lt;/font&gt;&lt;font size="2"&gt;&amp;#151;Under Intrepid's aircraft use policy, Mr.&amp;nbsp;Jornayvaz, Mr.&amp;nbsp;Harvey, and approved executive officers are allowed personal use of Intrepid's plane. Any personal use of aircraft may be taxable to the executive officer as a "fringe benefit" under Internal Revenue Service ("IRS") regulations. Additionally, Mr.&amp;nbsp;Jornayvaz and Mr.&amp;nbsp;Harvey may use the plane under dry-leases and reimburse Intrepid the lesser of the actual cost or the maximum amount chargeable under Federal Aviation Regulation&amp;nbsp;91-501(d). The value of personal use of the airplane was calculated based on the requirements provided by IRS regulations. &lt;/font&gt;&lt;/p&gt;
&lt;p style="FONT-FAMILY: times"&gt;&lt;font size="2"&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;An entity known as BH Holdings&amp;nbsp;LLC ("BH"), which is owned by entities controlled by Mr.&amp;nbsp;Jornayvaz and Mr.&amp;nbsp;Harvey, entered into a dry-lease arrangement with Intrepid to allow Intrepid use of an aircraft owned by BH for Intrepid business purposes. Additionally, in January 2009, a dry-lease arrangement by and between Intrepid and Intrepid Production Holdings&amp;nbsp;LLC ("IPH"), which is indirectly owned by Mr.&amp;nbsp;Jornayvaz, became effective to allow Intrepid use of an aircraft owned by IPH for Intrepid business purposes. Both dry-lease rates and dry-lease arrangements were approved by Intrepid's Audit Committee.&lt;/font&gt;&lt;/p&gt;
&lt;p style="FONT-FAMILY: times"&gt;&lt;font size="2"&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;In the year ended December&amp;nbsp;31, 2010, 2009, and the period from April&amp;nbsp;25, 2008, through December&amp;nbsp;31, 2008, Intrepid incurred dry-lease charges of $200,000, $330,000 and $292,000, respectively, for BH. As of December&amp;nbsp;31, 2010, and December&amp;nbsp;31, 2009, accounts payable balances due to BH were $27,000 and $67,000, respectively. In the year ended December&amp;nbsp;31, 2010, and 2009, Intrepid incurred dry-lease charges of $542,000 and $687,000, respectively, for IPH. As of December&amp;nbsp;31, 2010, and 2009, the accounts payable balance due to IPH was $17,000 and $23,000. &lt;/font&gt;&lt;/p&gt;
&lt;p style="FONT-FAMILY: times"&gt;&lt;font size="2"&gt;&lt;b&gt;&lt;i&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;Transition Services Agreement and Surface Use Easement Agreements&lt;/i&gt;&lt;/b&gt;&lt;/font&gt;&lt;font size="2"&gt;&amp;#151;On April&amp;nbsp;25, 2008, Intrepid, Intrepid Oil&amp;nbsp;&amp;amp; Gas,&amp;nbsp;LLC ("IOG"), and Intrepid Potash&amp;#151;Moab,&amp;nbsp;LLC ("Moab") executed a Transition Services Agreement. Pursuant to the Transition Services Agreement, IOG may request specified employees of Intrepid or its subsidiaries (other than Mr.&amp;nbsp;Jornayvaz and Mr.&amp;nbsp;Harvey) to provide a limited amount of geology, land title, and engineering services in connection with IOG's oil and gas ventures. Effective March&amp;nbsp;26, 2010, the term of the Transition Services Agreement was extended until April&amp;nbsp;24, 2011. &lt;/font&gt;&lt;/p&gt;&lt;/td&gt;&lt;/tr&gt;&lt;/table&gt;
