increase, if any, in the CPI-U (All Urban Consumers), as reported by the U.S.
Bureau of Labor Statistics, Index; provided, however, that the Services Base Fee
may not be decreased below the initial Services Base Fee provided in Section

index that gives comparable protection against inflation and the same method of
adjustment for increases in the new index shall be used to calculate increases

Section 11.12.”

Quarter, as applicable) period shall be due and payable by Delek Refining in
arrears on or before the tenth (10th) Business Day following receipt by Delek
Refining of such invoice. The Services Profit Share for any one-month period
shall be due and payable by Delek Refining in arrears on or before the tenth
(10th) Business Day of the second month following such period. Any past due
payments owed pursuant to this Article 6 shall accrue interest, payable on
demand, at the Prime Rate from the due date of the payment through the actual
date of payment. Payment of any Services Base Fee, Services Profit Share or
Shortfall Payment pursuant to this Article 6 shall be made by wire transfer of
immediately available funds to an account designated in writing by Delek
Marketing. If any such fee shall be due and payable on a day that is not a
Business Day, such payment shall be due and payable on the next succeeding
Business Day.”

amended in its entirety to read as follows:

Force Majeure event to perform its obligations under this Agreement, then upon
the delivery by such Party (the “Force Majeure Party”) of written notice (a
“Force Majeure Notice”) and full particulars of the Force Majeure event within a
reasonable time after the occurrence of the Force Majeure event relied on, the

paid pursuant to clause (A)(i) and (B) from and after the third anniversary of
the Effective Date, Delek Refining shall be required to continue to make
payments for the Services Base Fee and Services Profit Share for volumes
actually sold under this Agreement, provided that the aggregate minimum amount
of such Services Profit Share specified in Section 6.1(b) shall not apply for
purposes of this clause (B).”
