A. GENERAL; TERMS OF PAYMENT

1. FOR VALUE RECEIVED, the undersigned, Delek US Holdings Inc., a corporation organized under the laws of the State of Delaware (the “Borrower”), hereby promises to pay to the order of BANK LEUMI USA (the “Bank”), at its office at 564 Fifth Ave., New York, NY 10036 the principal sum of Fifty Million Dollars ($50,000,000.00) in lawful money of the United States of America and in immediately available funds, in installments in the amount of Two Million Dollars ($2,000,000) commencing April 1, 2011 and continuing on the first day of each July, October, January and April thereafter, until October 1, 2013 at which time the entire unpaid principal balance of this Note, and all accrued and unpaid interest hereon shall be due and payable.

The Borrower will pay interest on the unpaid principal amount hereof from time to time outstanding, computed on the basis of a 360-day year, at a rate per annum which shall be equal to 4.5% per annum above the Libor Rate (Reserve Adjusted) ^(*) for a Three month term, as calculated by the Bank, in the manner hereinafter provided, but in no event in excess of the maximum rate permitted by applicable law; provided, that in the event the Bank shall have determined that by reason of circumstances affecting the Libor Rate (Reserve Adjusted) adequate and reasonable means do not exist for ascertaining the Libor Rate (Reserve Adjusted) for any Interest Period, or the

Libor Rate				Libor Rate
(Reserve Adjusted)		=		1.00 — Libor Reserve Percentage

time remaining to the stated maturity date of this Note is less than the shortest Interest Period which may be elected hereunder, then the applicable rate of interest during such Interest Period shall be equal to the rate of interest designated by the Bank, and in effect from time to time, as its “Reference Rate” + 2.75% per annum adjusted when said Reference Rate changes, but in no event in excess of the maximum rate permitted by law (the Borrower acknowledges that the Reference Rate may not necessarily represent the lowest rate of interest charged by the Bank to customers) and in no event shall the per annum rate of interest charged hereunder be less than 5% at any time; further provided that if, by 11:00am New York time, three (3) business days prior to the end of any Interest Period, the Borrower has failed to timely notify the Bank of its election of the choice of interest rate for or length of the next Interest Period, then the interest rate in effect thereafter shall be at the Libor Rate (Reserve Adjusted) +4.5% per annum for an Interest Period the length of which shall be the same length as the immediately preceding Interest Period unless such Interest Period would end after the stated maturity date of this Note, in which case the Interest Period shall be of a duration equal to the next longest Interest Period which would end prior to such scheduled maturity date, provided further that no Libor Rate (Reserve Adjusted)-based loan shall be made less than one month before the stated maturity date of this Note or after the occurrence and continuance of an Event of Default. Interest hereunder shall be payable on the last day of each Interest Period and at maturity (whether by acceleration or otherwise). The term “Interest Period” as used in this Note shall mean a period of Three months (provided however that the first Interest Period shall end on January 1, 2011), with each successive period ending on the first day of each April, July, October and January. No Interest Period shall extend beyond the stated maturity date of this Note. The initial Interest Period for this Note shall begin on the day of the initial draw down under the Note, and each subsequent Interest Period shall begin on the last day of the immediately preceding Interest Period. If an Interest Period would otherwise end on a day that is not a Business Day, such Interest Period shall end on the next succeeding Business Day; provided, however, that, if any Interest Period would otherwise end on a day that is not a Business Day but is a day of the month after which no further Business Day occurs in such month, such Interest Period shall end on the next preceding Business Day and further provided that if any Interest Period commences on the last Business Day in a calendar month or if there is no corresponding day in the calendar month in which it is to end, then it shall end on the last Business Day in a calendar month. The Bank shall give notice to the Borrower of the interest rate determined for each Interest Period as provided herein, and such notice shall be conclusive and binding upon the Borrower for all purposes absent manifest error. The Borrower shall pay to the Bank to compensate it for any loss, cost or expense that the Bank determines is attributable to any prepayment of a loan made by the Bank to the Borrower using the Libor Rate (Reserve Adjusted). Such compensation shall be an amount equal to the excess (if any) of (i) the amount of interest that otherwise would have accrued on the principal amount so prepaid for the period from the date of such prepayment to the last day of the then current Interest Period for such loan at the applicable rate of interest for such loan provided for herein less (ii) the amount of interest that otherwise would have accrued on such principal amount from the date of such prepayment until the end of the then current Interest Period at a rate per annum equal to the interest component of the amount the Bank would have bid in The London Interbank market for dollar deposits of leading banks in amounts comparable to such principal amount and with maturities comparable to such period (as reasonably determined by the Bank). The term “Business Day” shall mean any day of the year on which the Bank is open for business (as required or permitted by law or otherwise) and on which dealings in U.S. dollar deposits are carried on in London, England.

If any law, treaty, rule, regulation or determination of a court or governmental authority or any change therein or in the interpretation or application thereof (each, a “Change in Law”) shall make it unlawful for the Bank to make Libor Rate (Reserve Adjusted)-based loans, or to maintain interest rates based on Libor, then in the former event, any obligation of the Bank contained herein or in any agreement of the Bank to make available such unlawful Libor Rate (Reserve Adjusted)-based loans shall immediately be cancelled, and in the latter event, any such unlawful Libor Rate (Reserve Adjusted)-based loans then outstanding shall be converted, at the Bank’s option, so that interest on the outstanding principal balance subject hereto is determined in relation to the Reference Rate as hereinabove provided; provided however, that if any such Change in Law shall permit any Libor Rate (Reserved Adjusted)-based loans to remain in effect until the expiration of the Interest Period applicable thereto, then such permitted Libor Rate (Reserve Adjusted)-based loans shall continue in effect until the expiration of such Interest Period. Upon the occurrence of any of the foregoing events, Borrower shall pay to the Bank immediately upon demand such amounts as may be necessary to compensate the Bank for any fines, fees, charges, penalties or other costs incurred or payable by the Bank as a result thereof and which are attributable to any Libor Rate (Reserve Adjusted) options made available to Borrower hereunder, and any reasonable allocation made by the Bank among its operations shall be conclusive and binding upon Borrower.

If any Change in Law or compliance by the Bank with any request or directive (whether or not having the force of law) from any central bank or other governmental authority shall:

	(A)		subject the Bank to any tax, duty or other charge with respect to any Libor Rate (Reserve Adjusted) options, or change the basis of taxation of payments to the Bank of principal, interest, fees or any other amount payable hereunder (except for changes in the rate of tax on the overall net income of the Bank); or
	(B)		impose, modify or hold applicable any reserve, special deposit, compulsory loan or similar requirement against assets held by, deposits or other liabilities in or for the account of, advances or loans by, or any other acquisition of funds by any office of the Bank; or
	(C)		impose on the Bank any other condition;

and the result of any of the foregoing is to increase the cost to the Bank of making, renewing or maintaining any Libor Rate (Reserve Adjusted)-based loan hereunder and/or to reduce any amount receivable by the Bank in connection therewith, then in any such case, Borrower shall pay to the Bank immediately upon demand such amounts as may be necessary to compensate the Bank for any additional costs incurred by the Bank and/or reductions in amounts received by the Bank which are attributable to such Libor Rate (Reserve Adjusted)-based loan. In determining which costs incurred by the Bank and/or reductions in amounts received by the Bank are attributable to any Libor Rate (Reserve Adjusted)-based loan made to Borrower hereunder, any reasonable allocation made by the Bank among its operations shall be conclusive and binding upon Borrower.

In addition, after this Note becomes due, at stated maturity or on acceleration, any unpaid balance hereof shall bear interest from such date until paid at a rate per annum equal to 3% above the rate of interest hereinabove indicated.

2. All Property (as hereinafter defined) held by the Bank shall be subject to a security interest in favor of the Bank as security for any and all Liabilities (as hereinafter defined). The term “Property” shall mean the balance of every deposit account of the Borrower with the Bank or any of the Bank’s nominees or agents and all other obligations of the Bank or any of its nominees or agents to the Borrower, whether now existing or hereafter arising, and all other personal property of the Borrower (including without limitation all money, accounts, general intangibles, goods, instruments, documents and chattel paper) which, or evidence of which, are now or at any time in the future shall come into the possession or under the control of or be in transit to the Bank or any of its nominees or agents for any purpose, whether or not accepted for the purposes for which it was delivered. The term “Liabilities” shall mean the indebtedness evidenced by this Note and all other indebtedness, liabilities and obligations of any kind of the Borrower to the Bank including without limitation all expenses, including attorneys’ fees, incurred by the Bank in connection with any such indebtedness, liabilities or obligations or any of the Property (including any sale or other disposition of the Property).

3. Prepayment. Borrower may prepay this note in whole or in part at any time upon not less than 3 days prior written notice to the Bank, provided that such prepayment is made on the last day of an Interest Period.

4. Manner of Payment. All payments by the Borrower on account of principal, interest or fees hereunder shall be made in lawful money of the United States of America, in immediately available funds. The Borrower authorizes (but shall not require) the Bank to debit any account maintained by the Borrower with the Bank, at any date on which a payment is due under this Note, in an amount equal to any unpaid portion of such payment. If any payment of principal or interest becomes due on a day on which the Bank is closed (as required or permitted by law or otherwise), such payment shall be made not later than the next succeeding Business Day except as may be otherwise provided herein, and such extension shall be included in computing interest in connection with such payment. In the event that any other Liabilities of the Borrower to the Bank are due at any time that the Bank receives a payment from the Borrower on account of this Note or any such other Liabilities of the Borrower, the Bank may apply such payments to amounts due under this Note or any such other Liabilities in such manner as the Bank, in its discretion, elects, regardless of any instructions from the Borrower to the contrary. The Bank or any holder may accept late payments, or partial payments, even though marked “payment in full” or containing words of similar import or other conditions, without waiving any of its rights.

	A.		At no time during the term of the Loan shall the Borrower pledge, assign or hypothecate any shares of stock or other ownership interests which it owns in any subsidiary or affiliate in which it owns a “controlling interest”, as such term is defined by Regulation S-X promulgated by the Securities and Exchange Commission (“Controlled Subsidiaries and Affiliates”), other than shares of stock or other ownership interests in Mapco Express, Inc., Delek Refining, Inc., or Delek Marketing & Supply, Inc, and any of their respective Controlled Subsidiaries and Affiliates that are presently pledged for their existing loan facilities (the “Existing Facilities”), or which may be required to be pledged under the Existing Facilities (collectively, the “Pledged Shares”). In the event that the Existing Facilities are refinanced with the existing or different lenders, the pledging of Pledged Shares may continue. However, in the event that the Existing Facilities are not refinanced as a part of the termination of the pledge of Pledged Shares, then such shares shall be subject to the restrictions contained in this paragraph and shall not be pledged, assigned or hypothecated, without the consent of Lender. In addition to the foregoing, at all times the Borrower shall maintain ownership of at least seventy five (75%) percent of the shares of issued and outstanding stock or ownership interests in the Controlled Subsidiaries and Affiliates in which it owns in excess of 75% of the issued and outstanding stock or other ownership interests as of the date hereof or in the future. Notwithstanding the foregoing, this provision shall in no way prohibit the current pledge of the 2,867,242 shares of Lion Oil Company that are currently pledged to the Bank and Israel Discount Bank of New York.

	C.		The ability of Borrower’s subsidiaries to upstream dividends or repay intercompany debt to the Borrower shall be maintained in any new debt arrangement entered into after the date hereof and any such ability shall be (a) not materially more restrictive than what exists in the Borrower’s subsidiaries’ existing debt arrangements in effect on the date hereof, or (b) otherwise satisfactory to the Lender.

	E.		Borrower shall not, directly or indirectly, declare, pay or make any dividend or distribution on any class of its capital stock or apply any of its funds, property, or assets to the purchase, redemption, or other retirement of any class of its capital stock; except, that, so long as no default or Event of Default exists under the Note or any of the Loan Documents, immediately prior to or after giving affect to any such payment, Borrower may make dividends or distributions to its shareholders not to exceed $15,000,000 in the aggregate in any fiscal year; provided, further, that, Borrower may make dividends or distributions to its shareholders in excess of such $15,000,000 aggregate amount in any fiscal year, so long as, concurrently with the making of any payment thereto, Borrower pays to Lender an amount equal to thirty (30%) percent of such excess dividend payment, which payment(s) will be applied by the Lender to the outstanding principal amount of the Note.
	F.		During the term of this Note, Borrower shall not make any Acquisitions (as hereinafter defined), in an aggregate amount in excess of $350,000,000 (the “Basket”).

2. No Waiver; Remedies Cumulative. No failure on the part of the Bank to exercise, and no delay in exercising any right hereunder shall operate as a waiver thereof nor shall any single or partial exercise by the Bank of any right hereunder preclude any other or further exercise thereof or the exercise of any other right. The remedies herein provided are cumulative and not exclusive of any remedies provided by any other instrument or document or under applicable law.

3. Closing Fees; Costs and Expenses. A one-time, non-refundable closing fee in the amount of $250,000 will be due and payable by Borrower to Bank upon the closing and funding of this Note.

4. Amendments. No amendment, modification or waiver of any provision of this Note nor consent to any departure by the Borrower therefrom shall be effective unless the same shall be in writing and signed by the Bank and then such waiver or consent shall be effective only in the specific instance and for the specific purpose for which given.

5. Construction. This Note shall be deemed to be a contract made under the laws of the State of New York and shall be construed in accordance with the laws of said State.

7. Severability. The provisions of this Note are severable, and if any provision shall be held invalid or unenforceable in whole or in part in any jurisdiction, then such invalidity or unenforceability shall not in any manner affect such provision in any other jurisdiction or any other provision of this Note in any jurisdiction.

This Note replaces in its entirety (i) that certain promissory note by Borrower in favor of Bank dated as of July 27, 2006 (as heretofore amended or modified) in the original principal amount of $30,000,000.00 as the same may have been paid down from time to time (the “2006 Note”) ; (ii) that certain promissory note by Borrower in favor of Bank dated May 12, 2008 (as heretofore amended or modified) in the original principal amount of $20,000,000.00 as the same may have been paid down from time to time (the “2008 Note”); (iii) that certain Letter Agreement dated May 7, 2008 by and between Borrower and Bank (as heretofore amended or modified) (the “2008 Letter Agreement”), and (iv) that certain Letter Agreement dated June 23, 2009 by and between Borrower and Bank (the “2009 Letter Agreement”); which 2006 Note, 2008 Note, 2008 Letter Agreement and 2009 Letter Agreement are hereby terminated and cancelled in all respects.
