Buyer's take of any Deficiency Volumes shall be in addition to its take obligations of the Required Monthly Quantity for the subject Contract Year. If Buyer elects to take delivery of Deficiency Volumes during the twenty-four (24) months following the Contract Month it failed to take the Deficiency Volumes, in addition to the Contract Price paid in the Contract Month it failed to take the Deficiency Volumes, Buyer shall pay Koch the product of the (i) difference between the Contract Price for the Month Buyer actually takes delivery of Deficiency Volumes and the Contract Price paid by Buyer in the Contract Month it failed to take the Deficiency Volumes multiplied by (ii) the Tons of Deficiency Volumes actually taken in the subject Month.

It is understood and agreed by Buyer that its obligation to pay for any Required Monthly Quantity or any Required Yearly Quantity it elects not to take during any Contract Year is not in the nature of damages. Rather, such a payment constitutes an alternative measure of performance elected by Buyer. This alternative measure is designed to compensate Koch for the risk of producing, procuring and supplying the Required Monthly Quantity and Required Yearly Quantity, while it is expressly understood that Buyer has accepted the market risk associated with such a contract. Therefore, if Buyer fails to take or to pay for the 7 Required Yearly Quantity or Required Monthly Quantity not taken in any Contract Year or Month respectively, Koch shall have no duty or obligation to resell or otherwise mitigate its potential losses arising from Buyer's failure to perform its contractual obligations.

If requested by Koch, Buyer shall provide proper documentation to Koch to verify that fifty percent (50%) of Buyer's Product Requirements have been purchased from Koch. If such documentation is not satisfactory to Koch, the parties will mutually agree to an independent auditor which will be allowed to audit Buyer's books and records to verify that fifty percent (50%) of Buyer's Product Requirements have been purchased from Koch. IV. QUALITY All Product delivered hereunder shall conform to the specifications set forth in Section T of Article I. All claims by Buyer that any Product delivered hereunder does not conform to the specifications set forth in said Section T, shall be made in writing and sent within thirty (30) days of Koch's delivery of such Product to the Delivery Point.

THE OMITTED INFORMATION HAS BEEN FILED SEPARATELY WITH THE SECRETARY OF THE SECURITIES AND EXCHANGE COMMISSION FOR PURPOSES OF SUCH REQUEST. 10 F. Fixed Charge Adjustment. The Fixed Charge shall be adjusted annually beginning January 1, 2000, based on the annual percentage change between the PPI as it existed on January 1 of the year that just ended (Subject Contract Year), and the PPI as it existed on January 1 of the year prior to the year that just ended (Preceding Contract Year) and shall be adjusted on January 1 of each calendar year. To calculate each annual adjustment, Buyer and Koch agree to take the difference in the PPI for the Subject Contract Year and the Preceding Contract Year and then divide by the Preceding Contract Year's PPI, which will yield the annual PPI percentage change. The annual PPI percentage change shall then be multiplied by the current Fixed Charge to get the Fixed Charge Adjustment rounded to the nearest cent. The Fixed Charge Adjustment will then be added to or subtracted, from the current Fixed Charge to establish the now Fixed Charge. For an example of such calculation, see Addendum A for calculations used in determining the Fixed Charge Adjustment for 1999. A Preliminary PPI Annual number, for the Subject Contract Year, may be used to calculate the Fixed Charge Adjustment until the Actual Annual PPI number, for the Subject Contract Year, is known. Once actualized, then credits/debits would be made accordingly and the actual new Fixed Charge would apply. F. Ammonia Pipeline Transportation Charge Adjustment. The Ammonia Pipeline Transportation Charge shall be increased or decreased whenever Koch incurs a cost change to reflect Koch's actual Product transportation costs from Koch's Facility to the Delivery Point.

Alpha shall be defined as follows: 1) October 1, 1999 through December 31, 1999: Additional Monthly Quantity Alpha, $/Ton ___________________________ ____________ *** 2) January 1, 2000 through December 31, 2000: Additional Monthly Quantity Alpha, $/Ton ___________________________ ____________ *** 3) January 1, 2001 through December 31, 2002: Additional Monthly Quantity Alpha, $/Ton ___________________________ ____________ ***INDICATES INFORMATION IN THIS DOCUMENT WHICH HAS BEEN OMITTED FROM THIS PUBLIC FILING PURSUANT TO A REQUEST BY THE COMPANY FOR CONFIDENTIAL TREATMENT BY THE SECURITIES AND EXCHANGE COMMISSION. THE OMITTED INFORMATION HAS BEEN FILED SEPARATELY WITH THE SECRETARY OF THE SECURITIES AND EXCHANGE COMMISSION FOR PURPOSES OF SUCH REQUEST. 11 *** H. Rail or Truck Transportation Costs. Notwithstanding any other provision of this Agreement, if ammonia pipeline transportation service is interrupted or curtailed, preventing Koch from making all or a portion of the required deliveries of Product hereunder, Koch shall use reasonable efforts to arrange rail or trucking transportation service from Koch's Facility to Buyer's Facility. Buyer shall be responsible for and reimburse Koch for all rail and/or trucking transportation costs incurred by Koch for deliveries of Product hereunder, including without limitation, demurrage charges. However, if Buyer is forced to pay a trucking and/or rail transportation rate that is higher than the Pipeline Transportation Charge and the increased transportation rate makes it uneconomical for Buyer to operate Buyer's Facility, forcing Buyer to shut down such facility, then Buyer shall have the right to suspend its performance hereunder by providing Koch with thirty (30) days written notice. However, Buyer shall not be allowed to suspend its performance hereunder if Koch, within its sole discretion, elects to pay the difference between the Ammonia Pipeline Transportation Charge and the trucking and/or rail transportation charges to the Delivery Point. If it remains uneconomical for Buyer to operate Buyer's Facility for sixty (60) consecutive days from the date Buyer gives Company notice solely because of the interruption or curtailment of pipeline Product deliveries hereunder and Koch elects not to pay the transportation differential, then Buyer shall have the right to terminate this Agreement by providing Koch with written notice within five (5) days of the end of the sixty (60) day period. I. Payment Term. *** ***INDICATES INFORMATION IN THIS DOCUMENT WHICH HAS BEEN OMITTED FROM THIS PUBLIC FILING PURSUANT TO A REQUEST BY THE COMPANY FOR CONFIDENTIAL TREATMENT BY THE SECURITIES AND EXCHANGE COMMISSION. THE OMITTED INFORMATION HAS BEEN FILED SEPARATELY WITH THE SECRETARY OF THE SECURITIES AND EXCHANGE COMMISSION FOR PURPOSES OF SUCH REQUEST. 12 ***. Koch shall also invoice Buyer for any additional amounts or refund any amounts as required by the terms set forth in Article I, Section N. *** Buyer agrees to accept facsimile copies of invoices from Koch. J. End of Term Payment. In the event Buyer has not purchased all Additional Yearly Quantity amounts, as defined in Article III, Section B.2, by December 31, 2002, Buyer shall make an "End of Term Payment" to Koch in the amount equal to (i) the difference between *** Tons and the sum of the Additional Monthly Quantity amounts taken, multiplied by (ii) $*** per Ton. In such case Koch shall invoice Buyer within thirty (30) days after December 31, 2002, and Buyer shall pay Koch the foregoing amount within two (2) days of the invoice date by Koch debiting Buyer's account, by using EFT. K. Letter of Credit. As assurance to Koch for Buyer's performance hereunder, Buyer agrees (i) to maintain the existing irrevocable standby letter of credit issued pursuant to the Previous Agreement in the amount of *** (the "LC") or an amended version of that LC in the amount of *** and (ii) at least one business day prior to the delivery by Koch of the 1998 Deficiency Volumes or execution of this Agreement, to deliver to Koch an additional Irrevocable standby letter of credit In the amount of *** ***INDICATES INFORMATION IN THIS DOCUMENT WHICH HAS BEEN OMITTED FROM THIS PUBLIC FILING PURSUANT TO A REQUEST BY THE COMPANY FOR CONFIDENTIAL TREATMENT BY THE SECURITIES AND EXCHANGE COMMISSION. THE OMITTED INFORMATION HAS BEEN FILED SEPARATELY WITH THE SECRETARY OF THE SECURITIES AND EXCHANGE COMMISSION FOR PURPOSES OF SUCH REQUEST. 13 (the "Additional LC") issued by a bank or other financial institution acceptable to the Credit Department of Koch. Such LC(s) shall be in the form of Addendum B attached hereto and made a part hereof. Buyer shall annually renew or cause the renewal or the letters of credit at least thirty (30) days prior to their respective expiration dates. Buyer shall maintain such letters of credit in the total amount of *** until such time the projected amount of the Unpaid Premium, as defined in Section L below, is less than *** at which time Koch shall allow Buyer to reduce the value of the letters of credit as the projected amount of Unpaid Premium is reduced, on a dollar for dollar basis. Subject to the foregoing, the letters of credit shall remain effective until 30 days after the term of this Agreement expires. If the bank or financial institution issuing one of the letters of credit shall at any time cease to be acceptable to the Credit Department of Koch as determined in its sole discretion, then within fifteen (15) calendar days after written notice from Koch, Buyer agrees it shall deliver to Koch a substitute irrevocable standby LC issued by a bank or other financial institution satisfactory to Koch, without terminating the original or then outstanding LC until such substitute LC has been delivered to Koch. If Buyer fails or refuses to cause the renewal of an existing LC or the delivery of a substitute LC within the required time period, such failure or refusal shall constitute a material breach of this Agreement entitling Koch to collect damages and to draw on the original or then outstanding letter of credit. In such event, Buyer shall have ten (10) days in which to cure such default and if such default is not cured within that time period, Koch may draw down on all or part of the Letter(s) of Credit, in addition to any other remedies Koch may be entitled to under this Agreement or at law or in equity. Koch shall give Buyer five (5) days notice prior to drawing on the LC. The parties specifically agree that in such case, if Koch chooses to draw down on the Letter(s) of Credit in an amount greater than any amount then due and owing under this Agreement, adequate consideration for Koch doing so exists due to Koch foregoing its rights to collect amounts due and owing under the Previous Agreement and instead entering into this Agreement with Buyer. L. Basis for Letter of Credit Reduction. Koch shall notify Buyer ninety (90) days in advance when the projected amount of the Unpaid Premium shall be expected to be less than ***. The "Unpaid Premium" shall be an amount equal ***INDICATES INFORMATION IN THIS DOCUMENT WHICH HAS BEEN OMITTED FROM THIS PUBLIC FILING PURSUANT TO A REQUEST BY THE COMPANY FOR CONFIDENTIAL TREATMENT BY THE SECURITIES AND EXCHANGE COMMISSION. THE OMITTED INFORMATION HAS BEEN FILED SEPARATELY WITH THE SECRETARY OF THE SECURITIES AND EXCHANGE COMMISSION FOR PURPOSES OF SUCH REQUEST. 14 to (i) the difference between 96,000 Tons and the sum of all Required Monthly Quantity Amounts paid for by Buyer multiplied by (ii) ***. Current projections indicate this should occur around the end of March 2001. When the Unpaid Premium is less than ***, Buyer shall be allowed to reduce the total value of the letters of credit by the amount the Unpaid Premium is less than ***; provided the letters of credit at the beginning of any Month covers 100 percent of the Unpaid Premium. In reducing letter(s) of credit pursuant to the above, Buyer agrees to first reduce entirely the most recently issued letter of credit before reducing the letter of credit issued earlier. M. Additional Credit. Koch may from time to time demand different terms of payment or additional assurance of payment, or other credit terms whenever Koch within its good faith discretion deems itself insecure because the prospect for payment or performance reasonably appears impaired. In any such event, and upon written notice specifying the event warranting the change in terms of payment, additional assurance of payment, or credit, Koch may suspend further deliveries pending agreement to the revised terms, including, but not limited to, pending agreement of Buyer to the posting of an appropriate bond, an additional letter of credit or other security acceptable to Koch to further secure Buyer's obligations hereunder. If Buyer fails or refuses to give adequate assurance of performance or payment upon demand therefor, Koch may treat such failure or refusal as a repudiation and breach of this Agreement, thereby entitling Koch to exercise all remedies provided for under this Agreement and any other remedy it may have at law or in equity. VII. DELIVERY A. Required Yearly Quantity. Subject to variations as may be necessitated due to a Force Majeure event as set out in Article X Koch shall deliver the Required Yearly Quantity, and Buyer shall take delivery of the Required Yearly Quantity in equal quantities of two thousand (2,000) Tons per Month during Contract Year 2000 and three thousand (3,000) Tons per Month during Contract Years 2001 and 2002. Buyer shall notify Koch no later than the 1st calendar day of the Month immediately prior to the Month of delivery of the number of Product Tons it wishes to receive for such Month of delivery.

Notwithstanding anything seemingly to the contrary herein, if Buyer makes a Buyout Payment, this Agreement shall be deemed automatically terminated except for Articles IV and V and except for the return to Buyer of any undrawn or partially undrawn Letters of Credit. 16 C. Buy Out Payment. In the event a Buy Out Payment is called for as set forth above, Koch shall send an invoice to Buyer for the payment in an amount equal to ***. Buyer shall pay Koch the foregoing amount within two (2) days of the invoice date by Koch debiting Buyer's bank account using EFT. IX. TAXES A. All present and future taxes, including, but not limited to, the Superfund Tax, (referred to herein as "Taxes") relating to the Product delivered hereunder, including all new taxes or increases in existing taxes including excise taxes (but excluding Koch's net income, excess profits, or corporate franchise taxes) imposed by any governmental authority upon the manufacture, use, sale, or delivery of the Product, shall be for Buyer's account, unless Buyer delivers to Koch current exemption certificates evidencing Buyer's exemption from paying such Taxes. B. Buyer agrees to indemnify and hold harmless Koch and its successors and assigns from and against any and all excise taxes (but not including net income, excess profits, or corporate franchise taxes), inclusive of any penalty and interest, assessed at a future date against Koch by any governmental authority upon the manufacture, use, sale, or delivery of the Required Yearly Quantity and/or Additional Yearly Quantity, whether taken or not. X. FORCE MAJEURE A. Neither Koch, nor Buyer, shall be liable for any failure or delay in performance under this Agreement, except for the obligation to make money payments due hereunder for Product already purchased, due to a Force Majeure event. "Force Majeure," as used herein shall mean any event which may be due in whole or in part to any contingency, delay, failure, cause or other occurrence of any nature beyond a party's reasonable control, whether it is presently occurring or occurs in the future, which (i) prevents Koch from producing, selling, purchasing or ***INDICATES INFORMATION IN THIS DOCUMENT WHICH HAS BEEN OMITTED FROM THIS PUBLIC FILING PURSUANT TO A REQUEST BY THE COMPANY FOR CONFIDENTIAL TREATMENT BY THE SECURITIES AND EXCHANGE COMMISSION. THE OMITTED INFORMATION HAS BEEN FILED SEPARATELY WITH THE SECRETARY OF THE SECURITIES AND EXCHANGE COMMISSION FOR PURPOSES OF SUCH REQUEST. 17 transporting the Product or (ii) which prevents Product from being used at Buyer's chemical facility in El Dorado, Arkansas (referred to hereafter as Buyer's Facility). B. The term "Force Majeure" shall not include (i) an event caused by a party's sole or contributory negligence; (ii) Koch's ability to sell or Buyer's ability to purchase Product at a price more advantageous than the Contract Price; (iii) Buyer's loss of markets for products produced at Buyer's Facility; (iv) shutdown of Seller's Facility or Buyer's Facility for reasons other than a Force Majeure event and (v) routine or scheduled maintenance at Seller's Facility or Buyer's Facility. C. If a Force Majeure event occurs, the declaring party may exercise its right under this Article by giving timely notice thereof to the other party setting forth with reasonable particularity the nature of the Force Majeure event. The declaring party shall use reasonable efforts to remedy the situation as quickly as possible and shall only be excused from performance hereunder during the duration of the Force Majeure event. The declaring party shall give the other party prompt notice of when the Force Majeure event ends. If Koch's deliveries of Product to Buyer are impeded due to a Force Majeure event, Koch shall have the right to apportion deliveries among its present and future customers (including regular customers not then under contract) and Koch's own requirements on such basis as may appear to Koch to be appropriate and equitable. Koch shall not be obligated to take any action which would result in increasing its performance costs under this Agreement beyond the costs which it would have incurred in the absence of such occurrence, delay or cause. In this regard, should Koch be required to operate the Koch Facility in a manner that results in Koch violating an operational flow order or similar gas pipeline order in order to meet its obligations under this Agreement, and the violation triggers a penalty or other charge to be incurred by Koch, Koch shall have the right to invoice Buyer for such charge on a per Ton basis as follows: ([the dollar amount per MMBTU of such a charge x Conversion Factor] x the number of Tons of Product produced using natural gas to which such charge applies). Buyer agrees to pay such charge in addition to the Contract Price per Ton and all other charges to be paid by Buyer to Koch for Product under this Agreement until such penalty or charge is curtailed as against Koch, provided, that in any such event, Buyer will have the option of declining to take 18 Product that is subject to such penalty or charge. The Required Yearly Quantity for the subject Contract Year shall be reduced by the Tons of Product Buyer declines to take under the preceding sentence. D. If a Force Majeure event occurs, Koch shall have the option, but not the obligation, to reduce the number of Tons of Product that it is required to deliver and Buyer is required to take or pay for hereunder; provided, that such reduction shall not affect the obligation of Koch to deliver, nor the obligation of Buyer (except as provided for herein) to take or pay for, the remaining Tons to be taken or paid for hereunder. If Koch elects to reduce the number of Tons Buyer is obligated to take or pay for in a particular Contract Year due to a Force Majeure event, or if the Force Majeure event continues into a subsequent Contract Year, Buyer's Required Yearly Quantity shall be reduced by number of Tons canceled by Koch due to the Force Majeure event. Koch's exercise of its option to cancel such affected Tons must be made by notice in writing by Koch to Buyer no later than thirty (30) days after the Force Majeure event no longer exists. If Koch does not exercise such option, the quantity of Product which was not delivered and received during the occurrence shall be delivered by Koch and received by Buyer after the Force Majeure event no longer exists during the term of this Agreement or within a reasonable period immediately following the expiration of this Agreement depending upon when Koch has Product available. If Koch delivers the Product after the Force Majeure event no longer exists during the term hereof, the Contract Price per Ton, or the Nola Index Price per Ton, whichever is applicable, for such Product shall be as set forth in Article VI calculated for the Month Koch actually delivers the Product. If, however, Koch delivers the Product after the end of this Agreement's term, the price for such Product shall be the Contract Price per Ton or the Nola Index price per Ton, whichever is applicable, according to the formula contained in Article VI and the definitions contained in Article I that would have been charged during the Month the Product is actually delivered if the term of this Agreement had continued in effect. If a Force Majeure event exists for a period of sixty (60) days or longer, or the declaring party gives notice that such event will last more than sixty (60) days, the non-declaring party shall have the option to terminate this Agreement by written notice to the other. Upon such termination, all obligations of the 19 parties hereunder shall terminate without liability to the other party, except for obligations which accrued prior to the effective date of the termination. E. If, at any time during this Agreement's term, any regulatory or governmental body adopts, issues, or publishes any action, rule, or order which directly or indirectly materially and adversely affects the rights or obligations of Koch under this Agreement or (each of the events described in hereafter referred to as "Adverse Action"), Koch shall notify Buyer in writing of the Adverse Action and the parties shall enter into negotiations to modify this Agreement. If negotiations regarding the Adverse Action do not result in Koch and Buyer agreeing on the terms of a modification to this Agreement within sixty (60) days of Koch's notice to Buyer, Koch shall have the right, but not the obligation, to suspend its performance hereunder until such time, if any, as the parties reach agreement on such a modification to this Agreement. In the event such Adverse Action continues for a period of one hundred twenty (120) days after Koch notifies Buyer of the same and the parties have not resolved the handling of the Adverse Action, either party may, but is not required to, terminate this Agreement upon thirty (30) days written notice to the other party within one hundred eighty (180) days of when Koch first notified buyer of the Adverse Action. Upon termination, all obligations by either party shall cease, except obligations to remit money due and payable. In the event of Adverse Action, upon written request, Koch shall provide Buyer with data or information reasonably necessary for Buyer to determine that such Adverse Action exists, subject to the confidentiality obligations of Article XVI of this Agreement. XI. REMEDIES FOR PAYMENT BREACH A. If Buyer is late in making any payment due to Koch under Article VI hereof, or otherwise, Koch may at its sole discretion by notice to Buyer elect one or more of the following courses of action: 1. Cease to make any further deliveries hereunder until Buyer has made the late payment and has taken steps to assure Koch that there shall be no such delinquencies in the future; 2. Refuse to make any further deliveries hereunder except upon cash payments before delivery; 3. Stop delivery of goods in the possession of a carrier or other bailee as provided by law; 20 4. Resell any Product concerned without further notice to Buyer and without affecting or abating Buyer's other obligations under this Agreement; 5. Set off any obligations Koch may have to Buyer against the payments due Koch hereunder; or 6. Draw upon any letter(s) of credit and/or other security provided by Buyer hereunder, provided any draw by Koch shall not exceed the amounts due and payable. If Buyer has not remedied late payments to the reasonable satisfaction of Koch within ten (10) days of such notice, Koch may at its option by notice to Buyer terminate this Agreement (without discharging any claim for breach), provided Koch shall not be allowed to terminate this Agreement if the amount of Buyer's liability to Koch does not exceed the outstanding LC amounts and Buyer makes up the amount drawn by Koch under the LC(s) within five (5) days of the date Koch draws on the LC(s); however, Koch shall have the right to suspend performance until Buyer replenishes the LC(s). The election by Koch of any of the courses of action hereto shall in no way limit any other remedies available to Koch under this Agreement or otherwise at law or in equity. B. If either party: 1. Voluntarily petitions under or otherwise seeks the benefit of any bankruptcy, reorganization, arrangement or insolvency law; or 2. Makes a general assignment for the benefit of creditors; or 3. Is adjudicated bankrupt or becomes insolvent; or 4. Allows a receiver or trustee of the business to be appointed; or 5. Fails to perform any part of this Agreement (other than provided for in Section A. of this Article) and upon written notice of such failure by the other party fails to remedy the same within thirty (30) days of such notice, or in the event such failure cannot reasonably be cured within thirty (30) days, does not initiate and pursue reasonable corrective action within said period of time, then, in any of said events, this Agreement may be terminated forthwith by written notice at the option of the other party with such other party retaining all its other rights and remedies at law or in equity. 21 XII.

Each and every right, power and remedy may be excused from time to time and so often and in such order as may be deemed expedient by the party, and the exercise of any such right, power or remedy shall not be deemed a waiver of the right to exercise at the same time or thereafter, any other right, power or remedy.
