Any Delivery Modification Notice issued by Buyer must be delivered to Seller no later than ten (10) days after Buyer’s receipt of Seller’s notice specifying the Commencement Date, after which time Buyer’s right to furnish a Delivery Modification Notice shall expire and the Agreement shall continue in full force and effect pursuant to its terms. If Buyer timely delivers a Delivery Modification Notice to Seller, then for the duration of the term of this Agreement (i) Buyer shall have the right, but not the obligation, to request from time to time that Seller sell Fuel to Buyer at a price to be mutually agreed by the Parties (it being understood that the pricing set forth in Section 5.2 shall not apply) and otherwise on the terms and subject to the conditions set forth herein, (ii) if so requested by Buyer, Seller shall only be obligated to sell Fuel to Buyer on an As Available Basis and Seller shall have no liability whatsoever if for any reason Buyer requests Fuel from Seller but Seller does not supply such Fuel, (iii) Seller shall be free to sell any and all Fuel from Seller’s Facility to third parties without any restrictions or obligations to Buyer whatsoever, and (iv) all of the terms and conditions in this Agreement pertaining to the take or pay nature of the Agreement, including the Minimum Annual Contract Quantity, shall be null and void or modified, as appropriate, mutatis mutandis, to reflect the foregoing.”

3. Section 5.2 of the Agreement is hereby deleted in its entirety and replaced with the following:
