Shell shall sell and deliver to Buyer, and Buyer shall purchase and accept from Shell, "Shell" Odorized HD-5 ("Product") in such quantities as Buyer shall order from time to time, but, during any calendar month, not less than 90% nor more (except at Shell's option) than all of the quantity specified for such month in the following schedule (in thousands of gallons): June 250 September 275 December 275 March 250 July 250 October 275 January 275 April 250 August 275 November 275 February 275 May 250 provided that Buyer shall order and accept deliveries in quantities and at intervals approximately equal during each month. 2.2 Quality - Warranty Disclaimer. The Product shall meet Shell's own specifications in effect at the time of delivery; but SHELL OTHERWISE MAKES NO WARRANTIES OF QUALITY, MERCHANTABILITY OR FITNESS AS TO THE PRODUCT, AND NONE SHALL BE IMPLIED. 2.3 Excess Quantities. Shell's sale and delivery during any month of more of any product than the quantity specified in the Schedule for that month, whether resulting from Shell's voluntary act, Shell's compliance with any allocation or other legal requirement, or any other cause, shall not be deemed to increase or otherwise amend such specified contract quantity as to any future month unless expressly so agreed in writing by Shell and Buyer. 3. PRICES. 3.1 Definitions. The price for the Product during July, August, September, April, May, June, F.O.B. Shell's Wood River Manufacturing Complex, shall be determined by adding the mean (sum of high/low OPIS prices divided by two) spot prices of propane at Mapco 140 as published by Oil Pricing Information Service (OPIS/Petroscan) for the following weekly OPIS report days: Thursday, Friday, Monday, Tuesday, and Wednesday and dividing the sum by five (5). This average price will have 2.25 cents per gallon differential added to produce the final selling price. During October, November, December, January, February, and March, the average price will have 3.25 cents per gallon differential added to produce the final selling price. This calculation will be completed by Shell on Thursday and Friday each week and effective for all product purchased beginning on the following Monday through Sunday. In the event OPIS fails to publish a price for any of these days, the day or days will be excluded from the calculation. 3.2 Quantity Limitation. Shell may, at its option, after the initial three months of the term, limit the quantity of any Product to be supplied in any month to a quantity which is the same percentage of contract quantity for that month as the average percentage of contract quantities actually delivered during the last preceding three months. 3.3 Payments. Buyer shall pay for the Product delivered on such terms as Shell shall prescribe, any of which may be altered or revoked by Shell at any time by notice to Buyer (which may be given by telephone or regular mail). Payment shall be deemed made when received by Shell. 4. DELIVERIES. 4.1 Places. The Product shall be delivered to Buyer at Shell's origin(s) (including pipeline terminals) at Wood River. However, Shell shall have the right at any time or times to change any place of delivery from origin to Buyer's destination(s) or from Buyer's destination to origin, and to change any origin either to another one specified in this article 4.1 or to a new one designated by Shell, by giving Buyer at least 15 days' prior notice or such shorter notice as may be reasonable in emergency situations. Such notice shall specify the new place of delivery, the effective date of the change, and, for Buyer's information, Shell's then-current price for the Product, F.O.B. that place.

Shell shall have no liability to Buyer for any defect in quality or shortage in quantity of the Product delivered unless (a) Buyer gives Shell notice of Buyer's claim within five days after delivery of such product, or in the case of any latent defect in quality, within five days after Buyer's discovery of such defect but in no event later than 30 days after delivery of such Product; (b) Shell is given reasonable opportunity to inspect the Product and to take and test samples thereof, and (c) in case of delivery by tank car, the claim, if for anything other than latent defect in quality, is allowed by Shell before the Product is unloaded from the tank car and, if for shortage in quantity, is for an amount in excess of 2% of the quantity shown on the bill of lading. In any event, Shell shall not be liable for any such claim in excess of the purchase price of the Product or for any consequential commercial damages. Every initial notice of claim shall set forth fully the facts on which the claim is based and shall be formally documented, in writing, to Shell within 60 days after initial notice. 9. EXCUSES FOR NONPERFORMANCE. Either Shell or Buyer will be excused from its obligations under this Contract (except financial) to the extent that performance is delayed or prevented by any circumstances reasonably beyond its control; or by fire, explosion, mechanical breakdown, strikes or other labor trouble, plant shutdown, riots or other civil disturbances, or voluntary or involuntary compliance with any law, regulation or request of any governmental authority; or by unavailability of or interference with Shell's usual sources of the Product or crude oils or other constituent materials, or the usual means of transporting any of the same, or that Shell cannot reasonably acquire access to railroad delivery equipment to deliver Product at Buyer's designation(s). If, due to any of the foregoing reasons, there should be a shortage of any Product from any source, Shell will not be obligated to purchase supplies from any other than its usual sources or to divert supplies in order to perform this Contract and may apportion its available supplies among its contract and non-contract customers and its own internal uses in such manner as it finds fair and reasonable. Quantities of Product consequentially undelivered will be deducted from the applicable remaining quantity obligation unless the parties agree otherwise in writing. 10. REMEDIES - WAIVER. In the event of Buyer's breach of any provision of this Contract; or Buyer's default in payment of any indebtedness to Shell, whether under this Contract or otherwise; or initiation of any bankruptcy, insolvency, receivership or other like proceeding by or against Buyer; or Buyer's failure to comply with any federal, state or municipal law, ordinance, regulation, order, license or permit relating to the operations of Buyer in connection with the Product, Shell shall have the right, in addition to any other rights or remedies it may have, to suspend deliveries hereunder or to terminate this Contract by giving Buyer notice. Shell's right to require strict performance of Buyer's obligations hereunder shall not be affected in any way by any previous waiver, forbearance, course of dealing, or trade custom or usage. 11. NOTICES. Every notice hereunder (except when otherwise specified and subject to any requirements of law) shall be given by certified or registered letter, telegram, facsimile (if Shell acknowledges receipt thereof) or telex and shall be deemed given when the letter is deposited in the U.S. mail or the telegram or telex or facsimile is dispatched, postage or charges prepaid, and directed to Shell or Buyer (as the case may be) at its address first herein specified, or at such other address as either may have substituted by notice so given to the other. 12. ENTIRETY - RELEASE - EXECUTION. This Contract, as of the beginning date of its term, contains the complete and exclusive agreement of, and terminates all prior contracts between Shell and Buyer concerning the Product, and Shell and Buyer each release the other from all claims arising in connection with any such prior contract including any railroad lease agreements, excepting however, claims of Shell against Buyer for indebtedness, reimbursement or indemnification. Neither this Contract nor any subsequent agreement amending or supplementing this Contract shall be binding on Shell unless and until it has been signed for Shell by a duly authorized representative, and commencement of performance hereunder or under any such subsequent agreement shall not constitute a waiver of this requirement.
