Once any Crude Oil is injected into the Supplemental Pipeline, such Crude Oil shall constitute Supplemental Material for purposes hereof. Each Supplemental Quantity shall be the amount reported by SPLP, which amounts shall be reported as positive numbers and shall indicate for each Supplemental Quantity whether it is an Eastbound or Westbound Shipment.

2.2    Certain Adjustments.

(a)    For purposes of all monthly calculations under the Supply and Offtake Agreement,

(i)    the Monthly Supplemental Quantity shall be deemed to be subject to an Included Transaction; provided that, if such Monthly Supplemental Quantity is a positive amount, such Included Transaction shall constitute an agreement by the Company to purchase Supplemental Material from Aron which shall represent a positive volume for purposes of the Supply and Offtake Agreement and if such Monthly Supplemental Quantity is negative, such Included Transaction shall constitute an agreement of Aron to purchase Supplemental Material from the Company which shall represent a negative volume for purposes of the Supply and Offtake Agreement, and in each case having a per barrel price equal to the Supplemental Price for that relevant month. The parties acknowledge that, for purposes of calculating the Aggregate Monthly Product True-up Amount in accordance with Schedule C to the Supply and Offtake Agreement, as a result of the foregoing, the Monthly Supplemental Quantity shall be added to Aggregate Product Sales for the relevant month and the Supplemental Material Product Group, so that if the Monthly Supplemental Quantity is a positive number (representing a purchase of Supplemental Material by the Company from Aron) it

shall increase Aggregate Product Sales and if the Monthly Supplemental Quantity is a negative number (representing a purchase of Supplemental Material by Aron from the Company) it shall decrease Aggregate Product Sales.

(ii)    the Nederland-Krotz Buy/Sell Transaction shall be deemed to result in:

(1)    the aggregate Shipped Quantity for such month being subject to an Included Transaction under which Aron has sold such quantity to the Company at the applicable price specified pursuant to the Nederland-Krotz Buy/Sell Confirmation and, for purposes of the month in which such aggregate Shipped Quantity is delivered, it shall be an increase to the Aggregate Product Sales for such month for the Supplemental Material Product Group; and

(2)    the aggregate Delivered Quantity for such month being subject to a Procurement Contract under which Aron has purchased such quantity from the Company at the applicable price specified pursuant to the Nederland-Krotz Buy/Sell Confirmation and, for purposes of the month in which such Delivered Quantity is delivered, it shall be an increase to Aggregate Crude Receipts for such month.

(b)    For purposes of calculating Net Payments under Section 10.1 of the Supply and Offtake Agreement, the following provisions shall apply:

(i)    “Adjusted Net Payment Conditions” shall consist of the following:

(3)    Aron shall have determined, in its reasonable judgment based on such inventory reports and other reasonable forms of evidence as may be available, that the sum of the Supplemental Step-in Inventory and the aggregate quantity of Supplemental Material injected into the Included Supplemental Facilities following the Inventory Transfer Time under the Supplemental Inventory Sales Agreement exceeds 300,000 Barrels; and

(4)    Aron shall have received the “Supplemental LC” complying with the terms and conditions specified in the Fee Letter.

(ii)    Once the Adjusted Net Payment Conditions have been satisfied, and for so long as the Supplemental LC is maintained and continues to satisfy the maintenance requirements specified in the Fee letter, the determination of Weekly Supply Value under Section 10.1(c) of the Supply and Offtake Agreement shall be adjusted by including in such determination the deemed Procurement Contract referred to in Section 2.2.(a)(ii)(2) above on the same basis as all other Procurement Contracts for purposes of such determination; provided that if Aron in its reasonable judgment determines, with respect to such deemed Procurement Contracts, that Contract Nominations are deviating from actual Shipped

Quantities in excess of immaterial and customary variances, then for purposes of determining the Weekly Supply Value Aron may from time to time adjust the amount of such Contract Nominations as it deems appropriate.

(iii)    The parties acknowledge and agree that neither the Supplemental Material nor the Included Supplemental Facilities shall at any time be reflected in the calculation of the Net Payment.

(iv)    The parties acknowledge and agree the deemed Procurement Contract referred to in Section 2.2.(a)(ii)(2) above shall be included in the determination of the Weekly Supply Value only under the terms and conditions specified above. Accordingly, at all times prior to the satisfaction of the Adjusted Net Payment Conditions and thereafter at any time at which the Supplemental LC has ceased to comply with the maintenance conditions specified in the Fee Letter, the determination of Weekly Supply Value shall be made as set forth in Section 10.1(d) of the Supply and Offtake Agreement, without including such deemed Procurement Contract as contemplated by Section 2.2(b)(ii) above.

2.3    Measurements. For purposes of determining the Monthly Supplemental Quantity, Aron shall rely on the pipeline statements provided by SPLP with respect to the volumes on the Supplemental Pipeline.

2.4    Shipments from Nederland Terminal to the Refinery.

Each Shipped Quantity shall be the determined based on the reports of the Independent Inspectors or SPMT as mutually agreed between the parties. The parties acknowledge that the net payment terms specified in the Nederland-Krotz Buy/Sell Confirmation are conditioned on the requirement that Shipped Quantities be transported by the Company only to the Refinery.

(b)    In connection with each Nederland-Krotz Buy/Seller Transaction, the parties shall comply with both the nomination and scheduling procedures set forth in the Nederland Terminaling Agreement (“Nederland Shipment Procedures”) and the Scheduling Protocol set forth in Schedule J to the Supply and Offtake Agreement.

(c)    The Company covenants and agrees that it will take such further actions, and execute, deliver and/or file such additional agreements, instruments and documents as Aron and its Affiliates may deem necessary or appropriate to confirm and maintain the lien and

security interest of Goldman Sachs Bank USA (“GS Bank”) in all Shipped Quantities and all documents of title (“Title Documents”) related thereto. If, in Aron’s reasonable judgment, GS Bank does not or would not hold a perfected first priority security interest in any quantities that are intended to be Shipped Quantities and/or Title Documents that would be related thereto, then such quantities shall not be released from the storage tanks at the Nederland Terminal unless the Company has provided to GS Bank additional credit support in form and substance satisfactory to GS Bank with respect to such quantities that the Company desires to ship.

(d)    Without limiting the generality of Section 2.4(d) above, the Company covenant and agrees, with respect to each Shipped Quantity, that any bill of lading issued with respect to the further transportation by the Company of such Shipped Quantity from the docks of the Nederland Terminal (as provided in the Nederland Shipment Procedures) shall be a non-negotiable bill of lading and the Company shall be the only consignee named thereon.

2.5    Title.

(a)    Aron shall retain title to all Supplemental Material quantities at all times while such quantities are held in the Supplemental Pipeline or in the Nederland Terminal in connection with the Supply and Offtake Agreement or the Big Spring S&O Agreement (including without limitation any linefill transferred to Aron in connection therewith), except to the extent otherwise provided under a buy/sell transaction between Aron and Alon USA with respect to an Excess Quantity.

(b)    As provided in the Nederland-Krotz Buy/Sell Confirmation, title to any Shipped Quantity shall transfer from Aron to the Company as such quantity passes the relevant delivery point provided therein and title to any Delivered Quantity shall transfer from the Company to Aron as such Supplemental Quantity or portion thereof passes the relevant delivered point as provided therein.
