Promptly after receipt of a Notice of Conversion or Continuation under this Section, the Administrative Agent shall provide each Lender with a copy thereof and, in the case of a Conversion to or a Continuation of a Borrowing comprised of Eurodollar Rate Advances, notify each Lender of the applicable interest rate under Section 2.07(b).

     (c) Certain Limitations. Notwithstanding anything in paragraphs 2.02(a) and 2.02(b) above:

          (i) at no time shall there be more than ten (10) Interest Periods applicable to outstanding Eurodollar Rate Advances and the Borrower may not select Eurodollar Rate Advances for any Borrowing at any time that an Event of Default has occurred and is continuing;

          (ii) if any Lender shall, at least one Business Day before the date of any requested Borrowing, Conversion or continuation, notify the Administrative Agent and the Borrower that the introduction of or any change in or in the interpretation of any law or regulation makes it unlawful, or that any central bank or other Governmental Authority asserts that it is unlawful, for such Lender or its Eurodollar Lending Office to perform its obligations under this Agreement to make Eurodollar Rate Advances or to fund or maintain Eurodollar Rate Advances, the right of the Borrower to select Eurodollar Rate Advances from such Lender shall be suspended until such Lender shall notify the Administrative Agent and the Borrower that the circumstances causing such suspension no longer exist, and the Advance made by such Lender in respect of such Borrowing, Conversion or continuation shall be an Alternate Base Rate Advance;

          (iii) if the Administrative Agent is unable to determine in good faith the Eurodollar Rate for Eurodollar Rate Advances comprising any requested Borrowing, the right of the Borrower to select Eurodollar Rate Advances for such Borrowing or for any subsequent Borrowing shall be suspended until the Administrative Agent shall notify the Borrower and the Lenders that the circumstances causing such suspension no longer exist, and each Advance comprising such Borrowing shall be an Alternate Base Rate Advance;

L.P. Credit Agreement

          (iv) if the Majority Lenders shall, at least one Business Day before the date of any requested Borrowing, notify the Administrative Agent and the Borrower that the Eurodollar Rate for Eurodollar Rate Advances comprising such Borrowing will not adequately reflect the cost to such Lenders of making or funding their respective Eurodollar Rate Advances, as the case may be, for such Borrowing, the right of the Borrower to select Eurodollar Rate Advances for such Borrowing or for any subsequent Borrowing shall be suspended until the Administrative Agent shall notify the Borrower and the Lenders that the circumstances causing such suspension no longer exist, and each Advance comprising such Borrowing shall be an Alternate Base Rate Advance;

          (v) if the Borrower delivers a Notice of Conversion or Continuation to the Administrative Agent but fails to select the duration of any Interest Period for any Eurodollar Rate Advances in accordance with the provisions contained in the definition of “Interest Period” in Section 1.01 and paragraph 2.02(b) above, the Administrative Agent shall so notify the Borrower and the Lenders and such Advances shall be made available to the Borrower on the date of such Borrowing as Eurodollar Rate Advances or, if an existing Advance, Converted into Eurodollar Rate Advances, in each case with an Interest Period equal to one month; and

          (vi) if the Borrower fails to deliver a Notice of Conversion or Continuation to the Administrative Agent with respect to any Eurodollar Rate Advance in accordance with Section 2.02(b)(i) hereof, such Eurodollar Rate Advances shall, at the end of the applicable Interest Period, be Converted into Alternate Base Rate Advances.

     (d) Notices Irrevocable. Each Notice of Borrowing and Notice of Conversion or Continuation, once delivered, shall be irrevocable and binding on the Borrower. In the case of any Borrowing which the related Notice of Borrowing specifies is to be comprised of Eurodollar Rate Advances, the Borrower shall indemnify each Lender against any loss, reasonable out-of-pocket cost or expense incurred by such Lender as a result of any failure by the Borrower to fulfill on or before the date specified in such Notice of Borrowing, the applicable conditions set forth in Article III that are not otherwise waived in writing, including, without limitation, any loss (including any loss of anticipated profits), cost or expense incurred by reason of the liquidation or reemployment of deposits or other funds acquired by such Lender to fund the Advance to be made by such Lender as part of such Borrowing when such Advance, as a result of such failure, is not made on such date.

     (e) Administrative Agent Reliance. Unless the Administrative Agent shall have received notice from a Lender before the date of any Borrowing that such Lender shall not make available to the Administrative Agent such Lender’s Pro Rata Share of the Borrowing, the Administrative Agent may assume that such Lender has made its Pro Rata Share of such Borrowing available to the Administrative Agent on the date of such Borrowing in accordance with Section 2.02(a) and the Administrative Agent may, in reliance upon such assumption, make available to the Borrower on such date a corresponding amount. If and to the extent that such Lender shall not have so made its Pro Rata Share of such Borrowing available to the Administrative Agent, such Lender and the Borrower severally agree to immediately repay to the Administrative Agent on demand such corresponding amount, together with interest on such amount, for each day from the date such amount is made available to the Borrower until the date such amount is repaid to the Administrative Agent, at (i) in the case of the Borrower, the interest rate applicable on such day to Advances comprising such Borrowing and (ii) in the case of such Lender, the Federal Funds Rate for such day. If such Lender shall repay to the Administrative Agent such corresponding amount and interest as provided above, such corresponding amount so repaid shall constitute such Lender’s Advance as part of such Borrowing for purposes of this Agreement even though not made on the same day as the other Advances comprising such Borrowing.

Holly Energy Partners -Operating
L.P. Credit Agreement

     (f) Lenders’ Obligations Several. The failure of any Lender to make the Advance to be made by it as part of any Borrowing shall not relieve any other Lender of its obligation, if any, to make its Advance on the date of such Borrowing. No Lender shall be responsible for the failure of any other Lender to make the Advance to be made by such other Lender on the date of any Borrowing.

     Section 2.03. Reduction of the Commitments.

     (a) The Borrower shall have the right, upon at least three Business Days’ notice to the Administrative Agent, to terminate in whole or reduce ratably in part the unused portion of the Commitment; provided that each partial reduction shall be in the aggregate amount of $1,000,000 or in integral multiples of $500,000 in excess thereof. Each notice delivered by the Borrower pursuant to this Section 2.03 shall be irrevocable; provided that a notice of termination of the Commitments delivered by the Borrower in connection with a refinancing or a sale may state that such notice is conditioned upon the effectiveness of other credit facilities or such sale agreement, in which case such notice may be revoked by the Borrower (by notice to the Administrative Agent on or prior to the specified effective date) if such condition is not satisfied.

     (b) Except as provided in the immediately preceding sentence, any reduction and termination of the Commitments pursuant to this Section 2.03 shall be applied ratably to each Lender’s Commitment and shall be permanent, with no obligation of the Lenders to reinstate such Commitments and the commitment fees provided for in Section 2.06(a) shall thereafter be computed on the basis of the Commitments as so reduced.

     Section 2.04. Prepayment of Advances.

     (a) Optional. The Borrower may prepay Advances, after giving by 11:00 a.m. (Dallas, Texas time) (i) in the case of Eurodollar Rate Advances, at least three Business Days’ or (ii) in case of Alternate Base Rate Advances, at least one Business Day’s, irrevocable prior written notice to the Administrative Agent stating the proposed date and aggregate principal amount of such prepayment; provided that, if a notice of prepayment is given in connection with a conditional notice of termination of the Commitments as contemplated by Section 2.03, then such notice of prepayment may be revoked if such notice of termination is revoked in accordance with Section 2.03. If any such notice is given, the Borrower shall prepay Advances comprising part of the same Borrowing in whole or ratably in part in an aggregate principal amount equal to the amount specified in such notice, together with accrued interest to the date of such prepayment on the principal amount prepaid and amounts, if any, required to be paid pursuant to Section 2.10 as a result of such prepayment being made on such date; provided, however, that each partial prepayment with respect to: (A) any Borrowing comprised of Alternate Base Rate Advances shall be made in an initial minimum aggregate principal amount of $500,000 and thereafter in $100,000 multiples in excess thereof and in an aggregate principal amount such that after giving effect thereto such Borrowing shall have a principal amount outstanding of at least $500,000 and (B) any Borrowing comprised of Eurodollar Rate Advances shall be made in an initial minimum aggregate principal amount of $1,000,000 and thereafter in $500,000 multiples in excess thereof and in an aggregate principal amount such that after giving effect thereto such Borrowing shall have a principal amount outstanding of at least $1,000,000. Full prepayments of any Borrowing are permitted without restriction of amounts. Each prepayment under this Section 2.04(a) shall be allocated between the Borrowings as determined by the Borrower.

     (b) Mandatory.

          (i) Advances Exceeding Commitments. On any date that the sum of the outstanding Advances plus the Letter of Credit Exposure exceeds the Commitments (including as a result of the reduction of Commitments pursuant to Section 2.03), the Borrower shall, to the extent of such excess, prepay to the Lenders on a pro rata basis the outstanding principal amount of the Advances or if all such Advances have been repaid, the Borrower shall deposit with the Administrative Agent into the Cash Collateral Account an amount equal to such excess.

          (ii) Accrued Interest. Each prepayment under this Section 2.04(b) shall be accompanied by accrued interest on the amount prepaid to the date of such prepayment and amounts, if any, required to be paid pursuant to Section 2.10 as a result of such prepayment.

     (c) Illegality. If any Lender shall notify the Administrative Agent and the Borrower that the introduction of or any change in or in the interpretation of any law or regulation makes it unlawful, or that any central bank or other Governmental Authority asserts that it is unlawful for such Lender or its Eurodollar Lending Office to perform its obligations under this Agreement to maintain any Eurodollar Rate Advances of such Lender then outstanding hereunder, (i) the Borrower shall, no later than 11:00 a.m. (Dallas, Texas time) (A) if not prohibited by law, on the last day of the Interest Period for each outstanding Eurodollar Rate Advance made by such Lender or (B) if required by such notice, on the second Business Day following its receipt of such notice prepay all of the Eurodollar Rate Advances made by such Lender then outstanding, together with accrued interest on the principal amount prepaid to the date of such prepayment and amounts, if any, required to be paid pursuant to Section 2.10 as a result of such prepayment being made on such date, (ii) such Lender shall simultaneously make an Alternate Base Rate Advance to the Borrower on such date in an amount equal to the aggregate principal amount of the Eurodollar Rate Advances prepaid to such Lender, and (iii) the right of the Borrower to select Eurodollar Rate Advances from such Lender for any subsequent Borrowings shall be suspended until such Lender shall notify the Administrative Agent that the circumstances causing such suspension no longer exist; provided, that such Lender agrees to use reasonable efforts to designate a different Applicable Lending Office if the making of such designation would avoid such payment, and would not, in its reasonable judgment, be otherwise disadvantageous to such Lender.

     (d) No Additional Right; Ratable Prepayment. The Borrower shall have no right to prepay any principal amount of any Advance except as provided in this Section 2.04, and except as provided in Section 2.04(a), all notices given pursuant to this Section 2.04 shall be irrevocable and binding upon the Borrower. Each payment of any Advance pursuant to this Section 2.04 shall be made in a manner such that all Advances comprising part of the same Borrowing are paid in whole or ratably in part.

     Section 2.05. Repayment of Advances. The Borrower shall repay to the Administrative Agent for the ratable benefit of the Lenders the outstanding principal amount of each Advance, together with any accrued interest thereon, on the Final Maturity Date or such earlier date pursuant to Section 7.02 or Section 7.03.

     Section 2.06. Fees.

     (a) Commitment Fees. The Borrower agrees to pay to the Administrative Agent for the account of each Lender a commitment fee on the daily amount by which such Lender’s Commitment exceeds the sum of such Lender’s outstanding Advances plus its Pro Rata Share of the aggregate Letter of Credit Exposure, at a rate equal to the Applicable Margin for commitment fees from the date of this Agreement until the Revolver Termination Date. All commitment fees required hereunder shall be due

     (c) Letter of Credit Fees. The Borrower agrees to pay to, with respect to Letters of Credit issued hereunder, the following fees: (i) to the Administrative Agent for the pro rata benefit of the Lenders, a fee per annum for each Letter of Credit issued hereunder equal to the Applicable Margin for letter of credit fees on the face amount of such Letter of Credit, but in no event less than $500.00 per year on each Letter of Credit, (ii) to the Administrative Agent, for each Issuing Bank, a per annum letter of credit fronting fee in an amount equal to the greater of (y) $500.00 and (z) 0.125% of the face amount of each Letter of Credit and (iii) to the applicable Issuing Bank any other fees agreed to in writing between the Borrower and such Issuing Bank. Each such fee shall be payable quarterly in arrears on the last day of each March, June, September and December for the previous calendar quarter, commencing on March 31, 2011, and on the Final Maturity Date.

     (d) If any Lender shall become a Defaulting Lender, then, notwithstanding Sections 2.06(a) and (c) above and without prejudicing any right or remedy that the Borrower may have with respect to, on account of, arising from or relating to any event pursuant to which such Lender shall be a Defaulting Lender, no commitment fee or letter of credit fees shall accrue for the account of such Lender from and after the date upon which such Lender shall have become a Defaulting Lender.

     Section 2.07. Interest. The Borrower shall pay interest on the unpaid principal amount of each Advance made by each Lender from the date of such Advance until such principal amount shall be paid in full, at the following rates per annum:

     (a) Alternate Base Rate Advances. If such Advance is an Alternate Base Rate Advance, a rate per annum equal at all times to the Alternate Base Rate in effect from time to time plus the Applicable Margin in effect from time to time, payable in arrears on the fifth (5^th) Business Day following the last day of each March, June, September and December for the previous calendar quarter, commencing March 31, 2011 and on the date such Alternate Base Rate Advance shall be paid in full, provided that upon the occurrence and during the continuance of any Event of Default, such Advance shall, at the written request of the Administrative Agent or the Majority Lenders, bear interest at a rate per annum equal to the Alternate Base Rate in effect from time to time plus the Applicable Margin plus two percent (2.00%) per annum, payable on written demand.

     (b) Eurodollar Rate Advances. If such Advance is a Eurodollar Rate Advance, a rate per annum equal at all times during the Interest Period for such Advance to the Eurodollar Rate for such Interest Period plus the Applicable Margin in effect from time to time, payable on the last day of such Interest Period, and, in the case of Interest Periods of more than three months duration, on each day which occurs during such Interest Period at intervals of three months from the first day of such Interest Period, provided that upon the occurrence and during the continuance of any Event of Default, such Advance shall, at the written request of the Administrative Agent or the Majority Lenders, bear interest at a rate per

Holly Energy Partners -Operating
L.P. Credit Agreement

annum equal to the Alternate Base Rate in effect from time to time plus the Applicable Margin plus two percent (2.00%) per annum, payable on written demand.

     (c) Additional Interest on Eurodollar Rate Advances. The Borrower shall pay to each Lender, so long as any such Lender shall be required under regulations of the Federal Reserve Board to maintain reserves with respect to liabilities or assets consisting of or including Eurocurrency Liabilities, additional interest on the unpaid principal amount of each Eurodollar Rate Advance of such Lender, from the effective date of such Advance until such principal amount is paid in full, at an interest rate per annum equal at all times to the remainder obtained by subtracting (i) the Eurodollar Rate for the Interest Period for such Advance from (ii) the rate obtained by dividing such Eurodollar Rate by a percentage equal to 100% minus the Eurodollar Rate Reserve Percentage of such Lender for such Interest Period, payable on each date on which interest is payable on such Advance. Such additional interest payable to any Lender shall be determined by such Lender and notified to the Borrower in writing through the Administrative Agent (such notice to include the detailed calculation of such additional interest, which calculation shall be conclusive in the absence of manifest error).

     (d) Usury Recapture.

          (i) If, with respect to any Lender, the effective rate of interest contracted for under the Credit Documents, including the stated rates of interest and fees contracted for hereunder and any other amounts contracted for under the Credit Documents which are deemed to be interest, at any time exceeds the Maximum Rate, then the outstanding principal amount of the loans made by such Lender hereunder shall bear interest at a rate which would make the effective rate of interest for such Lender under the Credit Documents equal the Maximum Rate until the difference between the amounts which would have been due at the stated rates and the amounts which were due at the Maximum Rate (the “Lost Interest”) has been recaptured by such Lender.

          (ii) If, when the loans made hereunder are repaid in full, the Lost Interest has not been fully recaptured by such Lender pursuant to the preceding paragraph, then, to the extent permitted by law, for the loans made hereunder by such Lender the interest rates charged under Section 2.07 hereunder shall be retroactively increased such that the effective rate of interest under the Credit Documents was at the Maximum Rate since the effectiveness of this Agreement to the extent necessary to recapture the Lost Interest not recaptured pursuant to the preceding sentence and, to the extent allowed by law, the Borrower shall pay to such Lender the amount of the Lost Interest remaining to be recaptured by such Lender.

          (iii) Notwithstanding the foregoing or any other term in this Agreement and the Credit Documents to the contrary, it is the intention of each Lender and the Borrower to conform strictly to any applicable usury laws. Accordingly, if any Lender contracts for, charges, or receives any consideration which constitutes interest in excess of the Maximum Rate, then any such excess shall be canceled automatically and, if previously paid, shall at such Lender’s option be applied to the outstanding amount of the loans made hereunder by such Lender or be refunded to the Borrower.

     (e) Default Rate on Other Obligations. After the occurrence and during the continuance of any Event of Default, all Obligations other than those described in Sections 2.07(a) and (b) shall bear interest, at the written request of the Administrative Agent or the Majority Lenders, at a rate per annum equal at all times to the otherwise applicable interest rate plus two percent (2.00%) per annum, payable on written demand.

     Section 2.08. Payments and Computations.

Holly Energy Partners -Operating
L.P. Credit Agreement

     (a) Payment Procedures. The Borrower shall make each payment under this Agreement and under the Notes not later than 11:00 a.m. (Dallas, Texas time) on the day when due in Dollars to the Administrative Agent, in same day funds without deduction (except for deductions made pursuant to a Legal Requirement), setoff, or counterclaim of any kind and shall send notice of such payments to the Administrative Agent at 1700 Lincoln Street, Suite 600, Denver, Colorado 80203, Attention: Suzanne Ridenhour. The Administrative Agent shall promptly thereafter cause to be distributed like funds relating to the payment of principal, interest, or fees ratably (other than amounts payable solely to the Administrative Agent, the relevant Issuing Bank, or a specific Lender pursuant to Section 2.06(b), 2.06(c), 2.10, 2.11, 2.12, 2.13 8.05, 9.04 or 9.07) in accordance with each Lender’s Pro Rata Share to the Lenders for the account of their respective Applicable Lending Offices, and like funds relating to the payment of any other amount payable to any Lender or any Issuing Bank to such Lender for the account of its Applicable Lending Office, in each case to be applied in accordance with the terms of this Agreement.

     (b) Computations. All computations of interest based on the Alternate Base Rate shall be made by the Administrative Agent on the basis of a year of 365 or 366 days, as the case may be, and all computations of interest based on the Eurodollar Rate and the Federal Funds Rate and of fees shall be made by the Administrative Agent, on the basis of a year of 360 days, in each case for the actual number of days (including the first day, but excluding the last day) occurring in the period for which such interest or fees are payable. Each determination by the Administrative Agent of an interest rate or fee shall be conclusive and binding for all purposes, absent manifest error.

     (c) Non-Business Day Payments. Whenever any payment shall be stated to be due on a day other than a Business Day, such payment shall be made on the next succeeding Business Day, and such extension of time shall in such case be included in the computation of payment of interest or fees, as the case may be; provided, however, that if such extension would cause payment of interest on or principal of Eurodollar Rate Advances to be made in the next following calendar month, such payment shall be made on the next preceding Business Day.

     (d) Administrative Agent Reliance. Unless the Administrative Agent shall have received written notice from the Borrower prior to the date on which any payment is due to the Lenders that the Borrower shall not make such payment in full, the Administrative Agent may assume that the Borrower has made such payment in full to the Administrative Agent on such date and the Administrative Agent may, in reliance upon such assumption, cause to be distributed to each Lender on such date an amount equal to the amount then due such Lender. If and to the extent the Borrower shall not have so made such payment in full to the Administrative Agent, each Lender shall repay to the Administrative Agent forthwith on demand such amount distributed to such Lender, together with interest, for each day from the date such amount is distributed to such Lender until the date such Lender repays such amount to the Administrative Agent, at the Federal Funds Rate for such day.

     Section 2.09. Sharing of Payments, Etc. If any Lender shall obtain any payment (whether voluntary, involuntary, through the exercise of any right of set-off, or otherwise) on account of the Advances or Letter of Credit Obligations made by it in excess of its Pro Rata Share, as applicable, of payments on account of the Advances or Letter of Credit Obligations obtained by all the Lenders, such Lender shall notify the Administrative Agent and forthwith purchase from the other Lenders such participations in the Advances made by them or Letter of Credit Obligations held by them as shall be necessary to cause such purchasing Lender to share the excess payment ratably with each of them; provided, however, that if all or any portion of such excess payment is thereafter recovered from such purchasing Lender, such purchase from each Lender shall be rescinded and such Lender shall repay to the purchasing Lender the purchase price to the extent of such Lender’s ratable share (according to the

Holly Energy Partners -Operating
L.P. Credit Agreement

proportion of (a) the amount of the participation sold by such Lender to the purchasing Lender as a result of such excess payment to (b) the total amount of such excess payment) of such recovery, together with an amount equal to such Lender’s ratable share (according to the proportion of (i) the amount of such Lender’s required repayment to the purchasing Lender to (ii) the total amount of all such required repayments to the purchasing Lender) of any interest or other amount paid or payable by the purchasing Lender in respect of the total amount so recovered. The Borrower agrees that any Lender so purchasing a participation from another Lender pursuant to this Section 2.09 may, to the fullest extent permitted by law, exercise all its rights of payment (including the right of set-off) with respect to such participation as fully as if such Lender were the direct creditor of the Borrower in the amount of such participation.

     Section 2.10. Breakage Costs. If (a) any payment of principal of any Eurodollar Rate Advance is made other than on the last day of the Interest Period for such Advance, whether as a result of any payment pursuant to Section 2.04, the acceleration of the maturity of the Notes pursuant to Article VII, or for any other reason or (b) the Borrower fails to make a principal or interest payment with respect to any Eurodollar Rate Advance on the date such payment is due and payable, the Borrower shall, within ten days of any written demand sent by any Lender to the Borrower through the Administrative Agent (which demand shall provide a statement explaining the amount and setting forth the computation of any such loss or expense), pay to the Administrative Agent for the account of such Lender any amounts required to compensate such Lender for any additional losses, out-of-pocket costs or expenses which it may reasonably incur as a result of such payment or nonpayment, including, without limitation, any loss (including loss of anticipated profits), cost or expense incurred by reason of the liquidation or reemployment of deposits or other funds acquired by any Lender to fund or maintain such Advance.

     Section 2.11. Increased Costs.

     (a) Eurodollar Rate Advances. If, due to either (i) the introduction of or any change (other than any change by way of imposition or increase of reserve requirements included in the Eurodollar Rate Reserve Percentage) in or in the interpretation of any law or regulation occurring on or after the date of this Agreement (including, without limitation, the Dodd-Frank Wall Street Reform and Consumer Protection Act and any regulations pursuant thereto, regardless of when enacted, adopted or issued) or (ii) the compliance with any guideline or request from any central bank or other Governmental Authority (whether or not having the force of law), there shall be any increase occurring on or after the date of this Agreement in the cost (other than costs attributable to the imposition of, or any change in the rate of, any Taxes or Excluded Taxes) to any Lender of agreeing to make or making, funding or maintaining Eurodollar Rate Advances, then the Borrower shall from time-to-time, upon demand by such Lender (with a copy of such demand to the Administrative Agent), promptly pay to the Administrative Agent for the account of such Lender additional amounts sufficient to compensate such Lender for such increased cost; provided, that, before making any such demand, such Lender agrees to promptly notify the Borrower and to use reasonable efforts (consistent with its internal policy and legal and regulatory restrictions) to designate a different Applicable Lending Office if the making of such a designation would avoid the need for, or reduce the amount of, such increased cost and would not, in its reasonable judgment, be otherwise disadvantageous. A certificate as to the amount of such increased cost and detailing the calculation of such cost submitted to the Borrower and the Administrative Agent by such Lender shall be conclusive and binding for all purposes, absent manifest error.

     (b) Capital Adequacy. If any Lender or Issuing Bank reasonably determines that its required compliance with any law or regulation or any guideline or request from any central bank or other Governmental Authority, including, without limitation the implementation of the Dodd-Frank Wall Street Reform and Consumer Protection Act (whether or not having the force of law) affects or would affect the amount of capital required or expected to be maintained by such Lender or Issuing Bank or any

Holly Energy Partners -Operating
L.P. Credit Agreement

corporation controlling such Lender or Issuing Bank and that the amount of the capital is increased by or based upon the existence of such Lender’s commitment to lend or such Issuing Bank’s commitment to issue the Letters of Credit and other commitments of this type, then, upon thirty days’ prior written notice by such Lender or Issuing Bank (with a copy of any such demand to the Administrative Agent), the Borrower shall promptly pay to the Administrative Agent for the account of such Lender or Issuing Bank, as the case may be, from time-to-time as specified by such Lender or Issuing Bank, additional amounts sufficient to compensate such Lender or Issuing Bank, in light of the circumstances, to the extent that such Lender or Issuing Bank, as the case may be, reasonably determines the increase in capital to be allocable to the existence of such Lender’s commitment to lend or such Issuing Bank’s commitment to issue the Letters of Credit under this Agreement. A certificate as to the amounts showing in reasonable detail the calculation of the amounts submitted to the Borrower by such Lender or Issuing Bank shall be presumptively correct, absent manifest error.

     (c) Letters of Credit. If any change in any law or regulation or in the interpretation thereof by any court or administrative or Governmental Authority charged with the administration thereof shall either (i) impose, modify, or deem applicable any reserve, special deposit, or similar requirement against letters of credit issued by, or assets held by, or deposits in or for the account of, an Issuing Bank or (ii) impose on an Issuing Bank any other condition regarding the provisions of this Agreement relating to the Letters of Credit or any Letter of Credit Obligations, and the result of any event referred to in the preceding clause (i) or (ii) shall be to increase the cost to such Issuing Bank of issuing or maintaining any Letter of Credit (which increase in cost shall be determined by such Issuing Bank’s reasonable allocation of the aggregate of such cost increases resulting from such event), then, upon demand by such Issuing Bank, the Borrower shall pay to the Administrative Agent for the account of such Issuing Bank, from time to time as specified by such Issuing Bank, additional amounts which shall be sufficient to compensate such Issuing Bank for such increased cost. A certificate as to such increased cost incurred by such Issuing Bank, as a result of any event mentioned in clause (i) or (ii) above, and detailing the calculation of such increased costs submitted by such Issuing Bank to the Borrower, shall be conclusive and binding for all purposes, absent manifest error.

     Section 2.12. Taxes.

     (a) No Deduction for Certain Taxes. Any and all payments by the Borrower shall be made, in accordance with Section 2.08, free and clear of and without deduction for any and all present or future taxes, levies, imposts, deductions, charges or withholdings, and all liabilities with respect thereto, excluding, in the case of each Lender, each Issuing Bank and the Administrative Agent, (i) taxes imposed on its income, and franchise taxes and branch profits taxes imposed on it, by the United States of America, the jurisdiction under the laws of which such Lender, such Issuing Bank or the Administrative Agent (as the case may be) is organized, the jurisdiction in which its principal office or Applicable Lending Office is located, or any political subdivision of the foregoing, (ii) in the case of any Non-U.S. Lender (other than an assignee pursuant to a request by the Borrower under Section 2.15), any withholding tax that is imposed on amounts payable to such Non-U.S. Lender at the time such Non-U.S. Lender becomes a party to this Agreement (or designates a new lending office) or is attributable to such Non-U.S. Lender’s failure or inability (other than as a result of a change in law) to comply with Section 2.12(c), except to the extent that such Non-U.S. Lender (or its assignor, if any) was entitled, at the time of designation of a new lending office (or assignment), to receive additional amounts from the Borrower with respect to such withholding tax pursuant to Section 2.12(a), and (iii) any United States withholding tax imposed by FATCA (all such taxes collectively referred to as “Excluded Taxes”, and all such taxes, levies, imposts, deductions, charges, withholdings and liabilities other than the Excluded Taxes being hereinafter referred to as “Taxes”). If the Borrower shall be required by law to deduct any Taxes from or in respect of any sum payable to any Lender, any Issuing Bank, or the Administrative Agent, (i) the sum

payable shall be increased as may be necessary so that, after making all required deductions (including deductions applicable to additional sums payable under this Section 2.12), such Lender, such Issuing Bank, or the Administrative Agent (as the case may be) receives an amount equal to the sum it would have received had no such deductions been made; (ii) the Borrower shall make such deductions; and (iii) the Borrower shall pay the full amount deducted to the relevant taxation authority or other authority in accordance with applicable law. In addition, the Borrower agrees to pay any present or future stamp or documentary taxes or any other excise or property taxes, charges or similar levies which arise from any payment made or from the execution, delivery or registration of, or otherwise with respect to, this Agreement, the Notes, or the other Credit Documents (hereinafter referred to as “Other Taxes”).

     (b) Indemnification. The Borrower hereby indemnifies each Lender, each Issuing Bank, and the Administrative Agent for the full amount of Taxes or Other Taxes (including, without limitation, any Taxes or Other Taxes imposed by any jurisdiction on amounts payable under this Section 2.12) paid by such Lender, such Issuing Bank, or the Administrative Agent, as the case may be, and any liability arising therefrom or with respect thereto. Each payment required to be made by the Borrower in respect of this indemnification shall be made to the Administrative Agent for the benefit of any party claiming such indemnification within thirty days from the date the Borrower receives written demand therefor from the Administrative Agent on behalf of itself as Administrative Agent, such Issuing Bank, or any such Lender.

     (c) Lender Tax Status. Each Lender and Issuing Bank that is not organized under the laws of the United States of America or a state thereof (a “Non-U.S. Lender”) agrees that it shall deliver to the Borrower and the Administrative Agent on the date of this Agreement or upon, and as a condition to, the effectiveness of any Assignment and Acceptance (i) two duly completed copies of United States Internal Revenue Service Form W-8BEN or W-8ECI or successor applicable form, as the case may be, certifying in each case that such Lender is entitled to receive payments under this Agreement and the Notes payable to it, without deduction or withholding of any United States federal income taxes, (ii) if applicable, an Internal Revenue Service Form W-8 or successor applicable form, as the case may be, to establish an exemption from United States backup withholding, and (iii) any other governmental forms which are necessary or required under an applicable tax treaty or otherwise by law to reduce or eliminate any withholding tax which have been reasonably requested by the Borrower. Each Lender that is organized under the laws of the United States of America or a state thereof shall deliver to the Borrower and the Administrative Agent on the date of this Agreement or upon, and as a condition to, the effectiveness of any Assignment and Acceptance an Internal Revenue Service Form W-9 or successor form to establish an exemption from United States backup withholding. Each Lender which delivers to the Borrower and the Administrative Agent a Form W-8BEN or W-8ECI and Form W-8 or W-9 pursuant to the foregoing sentences further undertakes to deliver to the Borrower and the Administrative Agent two further copies of the said documents and Form W-8BEN or W-8ECI and Form W-8 or W-9, or successor applicable forms, or other manner of certification, as the case may be, on or before the date that any such documents or form expires or becomes obsolete or after the occurrence of any event requiring a change in the most recent letter and form previously delivered by it to the Borrower and the Administrative Agent, and such extensions or renewals thereof as may reasonably be requested by the Borrower and the Administrative Agent certifying in the case of a Form W-8BEN or W-8ECI that such Lender is entitled to receive payments under this Agreement without deduction or withholding of any United States federal income taxes. If an event (including without limitation any change in treaty, law or regulation) has occurred prior to the date on which any delivery required by the preceding sentence would otherwise be required which renders all such forms inapplicable or which would prevent any Lender from duly completing and delivering any such letter or form with respect to it and such Lender advises the Borrower and the

L.P. Credit Agreement

Administrative Agent that it is not capable of receiving payments without any deduction or withholding of United States federal income tax, and in the case of a Form W-8 or W-9, establishing an exemption from United States backup withholding tax, such Lender shall not be required to deliver such letter or forms.

     (d) FATCA. If a payment made to the Administrative Agent, a Lender, or an Issuing Bank under this Agreement would be subject to United States federal withholding tax imposed by FATCA if the Administrative Agent, such Lender, or such Issuing Bank fails to comply with the applicable reporting requirements of FATCA (including those contained in Section 1471(b) or 1472(b) of the Code, as applicable), the Administrative Agent, such Lender, or such Issuing Bank shall deliver to the Withholding Agent, at the time or times prescribed by law and at such time or times reasonably requested by the Withholding Agent, such documentation prescribed by applicable law (including as prescribed by Section 1471(b)(3)(C)(i) of the Code) and such additional documentation reasonably requested by the Withholding Agent as may be necessary for the Withholding Agent to comply with its obligations under FATCA, to determine that the Administrative Agent, such Lender, or such Issuing Bank has complied with the Administrative Agent’s, such Lender’s, or such Issuing Bank’s obligations under FATCA or to determine the amount to deduct and withhold from such payment.

     (e) Refunds. If the Administrative Agent, a Lender or an Issuing Bank determines, in its sole discretion, that it has received a refund of any Taxes or Other Taxes as to which it has been indemnified by the Borrower or with respect to which the Borrower has paid additional amounts pursuant to this Section, it shall pay to the Borrower an amount equal to such refund (but only to the extent of indemnity payments made, or additional amounts paid, by the Borrower under this Section with respect to the Taxes or Other Taxes giving rise to such refund), net of all out-of-pocket expenses of the Administrative Agent, such Lender or such Issuing Bank, as the case may be, and without interest (other than any interest paid by the relevant Governmental Authority with respect to such refund), provided that the Borrower, upon the request of the Administrative Agent, such Lender or such Issuing Bank, agrees to repay the amount paid over to the Borrower (plus any penalties, interest or other charges imposed by the relevant Governmental Authority) to the Administrative Agent, such Lender or such Issuing Bank in the event the Administrative Agent, such Lender or such Issuing Bank is required to repay such refund to such Governmental Authority. This paragraph shall not be construed to require the Administrative Agent, any Lender or an Issuing Bank to make available its tax returns (or any other information relating to its taxes that it deems confidential) to the Borrower or any other Person.

     Section 2.13. Letters of Credit.

     (a) Commitment. From time to time from the date of this Agreement until the date which is five Business Days prior to the Revolver Termination Date, at the request of the Borrower or, if the Borrower makes such request to the Administrative Agent, the Administrative Agent, the applicable Issuing Bank shall, on the terms and conditions hereinafter set forth, issue, increase, or extend the expiration date of Letters of Credit for the account of the Borrower or any of its Subsidiaries on any Business Day. No Letter of Credit shall be issued, increased, or extended:

          (i) unless such issuance, increase, or extension would not cause the Letter of Credit Exposure to exceed the lesser of (A) $50,000,000.00 or (B) the aggregate amount of the unused Commitments;

          (ii) unless such Letter of Credit has an Expiration Date not later than the earlier of (A) twelve months after the date of issuance thereof (or, if extendable beyond such period, unless such

Holly Energy Partners -Operating
L.P. Credit Agreement

Letter of Credit is cancelable upon at least thirty days’ notice given by the applicable Issuing Bank to the beneficiary of such Letter of Credit) and (B) five days prior to the Revolver Termination Date;

          (iii) unless such Letter of Credit Documents are in form and substance acceptable to the applicable Issuing Bank in its sole discretion;

          (iv) unless such Letter of Credit is a standby letter of credit not supporting the repayment of indebtedness for borrowed money of any Person;

          (v) unless the Borrower has delivered to the applicable Issuing Bank a completed and executed Letter of Credit Application; or

          (vi) if any Lender is a Defaulting Lender, unless the applicable Issuing Bank has entered into arrangements, including the deposit by the Borrower with the Administrative Agent into the Cash Collateral Account such amount as such Issuing Bank may request, up to the maximum amount equal to the Letter of Credit Exposure of such Defaulting Lender, after giving effect to the provisions of Section 2.17(a)(iv).

     (b) Participations. Upon the date of the issuance or increase of a Letter of Credit, the applicable Issuing Bank shall be deemed to have sold to each other Lender and each other Lender shall have been deemed to have purchased from such Issuing Bank a participation in the related Letter of Credit Obligations equal to such Lender’s Pro Rata Share at such date and such sale and purchase shall otherwise be in accordance with the terms of this Agreement. Such Issuing Bank shall promptly notify each such participant Lender by telex, telephone, or telecopy of each Letter of Credit issued, increased, or extended or converted and the actual dollar amount of such Lender’s participation in such Letter of Credit.

     (c) Issuing. Each Letter of Credit shall be issued, increased, or extended pursuant to a Letter of Credit Application (or by telephone notice promptly confirmed in writing by a Letter of Credit Application), given not later than 11:00 a.m. (Dallas, Texas time) on the third Business Day before the date of the proposed issuance, increase, or extension of the Letter of Credit, and the Administrative Agent shall give to each Lender prompt notice thereof by telex, telephone or telecopy. Each Letter of Credit Application shall be given by hand delivery, telecopier, telex, e-mail, or other electronic transmission, confirmed in writing to the extent requested, specifying the information required therein. After the applicable Issuing Bank’s receipt of such Letter of Credit Application and upon fulfillment (or waiver in writing) of the applicable conditions set forth in Article III, such Issuing Bank shall issue, increase, or extend such Letter of Credit for the account of the Borrower or any applicable Subsidiary. Each Letter of Credit Application shall be irrevocable and binding on the Borrower.

     (d) Reimbursement. The Borrower hereby agrees to pay on demand to the applicable Issuing Bank an amount equal to any amount paid by such Issuing Bank under any Letter of Credit. In the event an Issuing Bank makes a payment pursuant to a request for draw presented under a Letter of Credit and such payment is not promptly reimbursed by the Borrower upon demand, such Issuing Bank shall give the Administrative Agent notice of the Borrower’s failure to make such reimbursement and the Administrative Agent shall promptly notify each Lender of the amount necessary to reimburse such Issuing Bank. Upon such notice from the Administrative Agent, each Lender shall promptly reimburse such Issuing Bank for such Lender’s Pro Rata Share of such amount and such reimbursement shall be deemed for all purposes of this Agreement to be an Advance to the Borrower transferred at the Borrower’s request to such Issuing Bank. If such reimbursement is not made by any Lender to such Issuing Bank on the same day on which the Administrative Agent notifies such Lender to make reimbursement to such Issuing Bank hereunder, such Lender shall pay interest on its Pro Rata Share thereof to such Issuing Bank

L.P. Credit Agreement

at a rate per annum equal to the Federal Funds Rate. The Borrower hereby unconditionally and irrevocably authorizes, empowers, and directs the Administrative Agent and the Lenders to record and otherwise treat such reimbursements to such Issuing Bank as Alternate Base Rate Advances under a Borrowing requested by the Borrower to reimburse such Issuing Bank which have been transferred to such Issuing Bank at the Borrower’s request.

     (e) Obligations Unconditional. The obligations of the Borrower under this Agreement in respect of each Letter of Credit shall be unconditional and irrevocable, and shall be paid strictly in accordance with the terms of this Agreement under all circumstances, including, without limitation, the following circumstances:

          (i) any lack of validity or enforceability of any Letter of Credit Documents;

          (ii) any amendment or waiver of, or any consent to, departure from any Letter of Credit Documents;

          (iii) the existence of any claim, set-off, defense, or other right which the Borrower may have at any time against any beneficiary or transferee of such Letter of Credit (or any Persons for whom any such beneficiary or any such transferee may be acting), the applicable Issuing Bank, or any other person or entity, whether in connection with this Agreement, the transactions contemplated in this Agreement or in any Letter of Credit Documents, or any unrelated transaction;

          (iv) any statement or any other document presented under such Letter of Credit proving to be forged, fraudulent, invalid, or insufficient in any respect or any statement therein being untrue or inaccurate in any respect to the extent the applicable Issuing Bank would not be liable therefor pursuant to the following Section 2.13(f); or

          (v) payment by the applicable Issuing Bank under such Letter of Credit against presentation of a draft or certificate which does not comply with the terms of such Letter of Credit;

provided, however, that nothing contained in this Section 2.13(e) shall be deemed to constitute a waiver of any remedies of the Borrower in connection with the Letters of Credit or the Borrower’s rights under Section 2.13(f) below.

     (f) Liability of Issuing Bank. The Borrower assumes all risks of the acts or omissions of any beneficiary or transferee of any Letter of Credit with respect to its use of such Letter of Credit. No Issuing Bank nor any of its officers or directors shall be liable or responsible for:

          (i) the use which may be made of any Letter of Credit or any acts or omissions of any beneficiary or transferee in connection therewith;

          (ii) the validity, sufficiency, or genuineness of documents, or of any endorsement thereon, even if such documents should prove to be in any or all respects invalid, insufficient, fraudulent, or forged;

          (iii) payment by an Issuing Bank against presentation of documents which do not comply with the terms of a Letter of Credit, including failure of any documents to bear any reference or adequate reference to the relevant Letter of Credit; or

Holly Energy Partners -Operating
L.P. Credit Agreement

          (iv) any other circumstances whatsoever in making or failing to make payment under any Letter of Credit (including an Issuing Bank’s own negligence),

except that the Borrower shall have a claim against the applicable Issuing Bank, and such Issuing Bank shall be liable to the Borrower to the extent of any direct, as opposed to consequential, damages suffered by the Borrower which the Borrower proves were caused by (A) such Issuing Bank’s willful misconduct, bad faith, or gross negligence in determining whether documents presented under a Letter of Credit comply with the terms of such Letter of Credit or (B) such Issuing Bank’s willful failure to make lawful payment under any Letter of Credit after the presentation to it of a draft and certificate strictly complying with the terms and conditions of such Letter of Credit. In furtherance and not in limitation of the foregoing, such Issuing Bank may accept documents that appear on their face to be in order, without responsibility for further investigation, regardless of any notice or information to the contrary.

     (g) Cash Collateral Account.

          (i) If the Borrower is required to deposit funds in the Cash Collateral Account pursuant to Sections 2.04(b), 2.13(a), 2.17(a), 7.02(b), or 7.03(b), then the Borrower and the Administrative Agent shall establish the Cash Collateral Account and the Borrower shall execute any documents and agreements that the Administrative Agent reasonably requests in connection therewith to establish the Cash Collateral Account and grant the Administrative Agent an Acceptable Security Interest in such account and the funds therein. The Borrower hereby pledges to the Administrative Agent and grants the Administrative Agent a security interest in (x) the Cash Collateral Account, whenever established, (y) all funds held in the Cash Collateral Account from time to time, and (z) all proceeds thereof as security for the payment of the Obligations.

          (ii) So long as no Event of Default exists, (A) the Administrative Agent may apply the funds held in the Cash Collateral Account only to the reimbursement of any Letter of Credit Obligations, and (B) the Administrative Agent shall promptly release to the Borrower at the Borrower’s written request any funds held in the Cash Collateral Account in an amount up to but not exceeding the excess, if any (immediately prior to the release of any such funds), of the total amount of funds held in the Cash Collateral Account over the Letter of Credit Exposure. During the existence of any Event of Default, the Administrative Agent may apply any funds held in the Cash Collateral Account to the Obligations in any order determined by the Administrative Agent, regardless of any Letter of Credit Exposure which may remain outstanding. The Administrative Agent may in its sole discretion at any time release to the Borrower any funds held in the Cash Collateral Account.

          (iii) The Administrative Agent shall exercise reasonable care in the custody and preservation of any funds held in the Cash Collateral Account and shall be deemed to have exercised such care if such funds are accorded treatment substantially equivalent to that which the Administrative Agent accords its own property, it being understood that the Administrative Agent shall not have any responsibility for taking any necessary steps to preserve rights against any parties with respect to any such funds.

     Section 2.14. Commitment Increase.

     (a) Subject to the conditions set forth in clauses (b) and (c) of this Section 2.14, the Borrower may request that the amount of the aggregate Commitments be increased one or more times, in each case in a minimum amount of $10,000,000 or in integral multiples of $10,000,000 in excess thereof; provided that, the aggregate Commitments may not exceed $375,000,000. No Lender shall have any obligation to increase its Commitment.

Holly Energy Partners -Operating
L.P. Credit Agreement

     (b) Each such increase shall be effective, without the consent of any Lender (other than any Lender increasing its Commitment) only upon the following conditions being satisfied: (i) no Default or Event of Default has occurred and is continuing at the time thereof or would be caused thereby, (ii) either the Lenders having Commitments hereunder at the time the increase is requested agree to increase their Commitments in the amount of the requested increase or other financial institutions satisfying the definitions of Eligible Assignee or Approved Affiliate agree to make a Commitment, (iii) such Lenders and other financial institutions, if any, shall have executed and delivered to the Administrative Agent a Commitment Increase Agreement or a New Lender Agreement, as applicable, and (iv) the Borrower shall have delivered such evidence of authority for the increase (including without limitation, certified resolutions of the applicable board of directors of the General Partner authorizing such increase) as the Administrative Agent may reasonably request.

     (c) Each financing institution to be added to this Agreement as described in Section 2.14(b)(ii) above shall execute and deliver to the Administrative Agent a New Lender Agreement, pursuant to which it becomes a party to this Agreement. Each Lender agreeing to increase its Commitment as described in Section 2.14(b)(ii) shall execute and deliver to the Administrative Agent a Commitment Increase Agreement pursuant to which it increases its Commitment hereunder. In addition, a Responsible Officer shall execute and deliver to the Administrative Agent, for each Lender being added to this Agreement, a Note payable to such new Lender in the principal amount of the Commitment of such Lender, and for each Lender increasing its Commitment, a replacement Note payable to such Lender, in the principal amount of the increased Commitment of such Lender. Each such Note shall be dated the effective date of the pertinent New Lender Agreement or Commitment Increase Agreement. Upon execution and delivery to the Administrative Agent of the Note and the execution by the Administrative Agent of the relevant New Lender Agreement or Commitment Increase Agreement, as the case may be, such new financing institution shall constitute a “Lender” hereunder with a Commitment as specified therein, or such existing Lender’s Commitment shall increase as specified therein, as the case may be, and the Administrative Agent shall notify all Lenders of such addition or increase, and the final allocations thereof, and provide a revised Schedule 1.01(a) reflecting such additions or increase.

     (d) The decision to increase its Commitment hereunder shall be at the sole discretion of each Lender. Any such increase in the Commitment shall have the same guarantees as, and be secured on a pari passu basis by the Collateral securing the Commitment prior to such increase.

     Section 2.15. Replacement of Lenders. If the Borrower is required pursuant to Section 2.07(c), 2.11 or 2.12 to make any additional payment to any Lender, or if any Lender’s obligation to make or continue, or to convert Alternate Base Rate Advances into, Eurodollar Advances shall be suspended pursuant to 2.02(c)(ii), 2.02(c)(iv) or 2.04(c), or if any Lender is a Defaulting Lender or a Non-Consenting Lender (any Lender so affected, an “Affected Lender”), the Borrower may elect, if such amounts continue to be charged or such suspension is still effective, to replace such Affected Lender as a Lender party to this Agreement, provided that (a) no Event of Default shall have occurred and be continuing at the time of such replacement; (b) such replacement shall be at the Borrower’s sole expense and effort, including the payment of the administrative fee referenced in Section 9.06(a); (c) concurrently with such replacement, another bank or other entity (which entity shall be an Eligible Assignee or an Approved Affiliate) shall agree, as of such date, to purchase for cash the Advances and other Obligations due to the Affected Lender pursuant to an assignment substantially in the form of Exhibit A and to become a Lender for all purposes under this Agreement and to assume all obligations of the Affected Lender which as to the Affected Lender shall be terminated as of such date and to comply with the requirements of Section 9.06 applicable to assignments; and (d) concurrently with such replacement, the Borrower shall pay to such Affected Lender in same day funds on the day of such replacement all interest, fees and other amounts then accrued but unpaid to such Affected Lender by the Borrower hereunder to

Holly Energy Partners -Operating
L.P. Credit Agreement

and including the date of termination, including without limitation payments due to such Affected Lender under Sections 2.07(c), 2.11 and 2.12. A Lender shall not be required to make any such assignment and delegation if, prior thereto, as a result of a waiver by such Lender or Issuing Bank, as applicable, or otherwise, the circumstances entitling the Borrower to require such assignment and delegation cease to apply.

     Section 2.16. Pari Passu Lien. All Obligations arising under the Credit Documents, including, without limitation, Obligations under this Agreement, Banking Service Obligations and Obligations under any Lender Hedging Agreement, shall be secured pari passu by the Collateral. For the avoidance of doubt, no Debt of any Excluded Subsidiary owing to any Lender, any Affiliate of a Lender, any non-Lender, or any non-Lender Affiliate party to a Swap Contract with any Excluded Subsidiary shall be secured by the Collateral or be considered an “Obligation” for purposes of the Credit Documents. No Lender or Affiliate of a Lender shall have any voting rights under any Credit Document as a result of the existence of obligations owed to it under any Lender Hedging Agreement or as a result of any Banking Service Obligation being owed to it, except as expressly provided herein.

     Section 2.17. Defaulting Lenders.

     (a) Adjustments. Notwithstanding anything to the contrary contained in this Agreement, if any Lender becomes a Defaulting Lender, then, until such time as that Lender is no longer a Defaulting Lender, to the extent permitted by applicable law:

          (i) Waivers and Amendments. That Defaulting Lender’s right to approve or disapprove any amendment, waiver or consent with respect to this Agreement shall be restricted as set forth in Section 9.01.

          (ii) Reallocation of Payments. Any payment of principal, interest, fees or other amounts received by the Administrative Agent for the account of that Defaulting Lender (whether voluntary or mandatory, at maturity, pursuant to Article VII or otherwise, and including any amounts made available to the Administrative Agent by that Defaulting Lender pursuant to Section 7.05), shall be applied at such time or times as may be determined by the Administrative Agent as follows: first, to the payment of any amounts owing by that Defaulting Lender to the Administrative Agent hereunder; second, to the payment on a pro rata basis of any amounts owing by that Defaulting Lender to the Issuing Banks hereunder; third, if so determined by the Administrative Agent or requested by an Issuing Bank or Borrower, to be held in the Cash Collateral Account for future funding obligations of that Defaulting Lender of any participation in any Letter of Credit; fourth, as the Borrower may request (so long as no Default or Event of Default exists), to the funding of any Advance in respect of which that Defaulting Lender has failed to fund its portion thereof as required by this Agreement, as determined by the Administrative Agent; fifth, if so determined by the Administrative Agent or requested by the Borrower, to be held in a non-interest bearing deposit account and released in order to satisfy obligations of that Defaulting Lender to fund Advances under this Agreement; sixth, to the payment of any amounts owing to the Lenders or the Issuing Banks as a result of any judgment of a court of competent jurisdiction obtained by any Lender or the Issuing Banks against that Defaulting Lender as a result of that Defaulting Lender’s breach of its obligations under this Agreement; seventh, so long as no Default or Event of Default exists, to the payment of any amounts owing to the Borrower as a result of any judgment of a court of competent jurisdiction obtained by the Borrower against that Defaulting Lender as a result of that Defaulting Lender’s breach of its obligations under this Agreement; and eighth, to that Defaulting Lender or as otherwise directed by a court of competent jurisdiction; provided that if (x) such payment is a payment of the principal amount of any Advances or Letter of Credit Obligations in respect of which that Defaulting Lender has not fully funded its appropriate share and (y) such Advances or Letter of Credit

Holly Energy Partners -Operating
L.P. Credit Agreement

Obligations was made at a time when the conditions set forth in Section 3.02 were satisfied or waived, such payment shall be applied solely to pay the Advances of, and Letter of Credit Obligations owed to, all non-Defaulting Lenders on a pro rata basis prior to being applied to the payment of any Advances of, or Letter of Credit Obligations owed to, that Defaulting Lender. Any payments, prepayments or other amounts paid or payable to a Defaulting Lender that are applied (or held) to pay amounts owed by a Defaulting Lender or to deposit into the Cash Collateral Account pursuant to this Section 2.17(a)(ii) shall be deemed paid to and redirected by that Defaulting Lender, and each Lender irrevocably consents hereto.

          (iii) Certain Fees. That Defaulting Lender shall not be entitled to receive or accrue any fees pursuant to Section 2.06 for any period during which that Lender is a Defaulting Lender (and the Borrower shall not be required to pay any such fee that otherwise would have been required to have been paid to that Defaulting Lender).

          (iv) Reallocation of Pro Rata Shares to Reduce Letter of Credit Exposure. Subject to this Section 2.17(a)(iv), during any period in which there is a Defaulting Lender, for purposes of computing the amount of the obligation of each non-Defaulting Lender to acquire, refinance or fund participations in Letters of Credit pursuant to Section 2.13, the “Pro Rata Share” of each non-Defaulting Lender shall be computed without giving effect to the Commitment of that Defaulting Lender; provided, that, (i) each such reallocation shall be given effect only if, at the date the applicable Lender becomes a Defaulting Lender, no Default or Event of Default exists; and (ii) the aggregate obligation of each non-Defaulting Lender to acquire, refinance or fund participations in Letters of Credit shall not exceed the positive difference, if any, of (1) the Commitment of that non-Defaulting Lender minus (2) the outstanding amount of Advances of that Lender.

     (b) Defaulting Lender Cure. If the Borrower, the Administrative Agent and the Issuing Banks agree in writing in their sole discretion that a Defaulting Lender should no longer be deemed to be a Defaulting Lender, the Administrative Agent will so notify the parties hereto, whereupon as of the effective date specified in such notice and subject to any conditions set forth therein (which may include arrangements with respect to deposits to the Cash Collateral Account), that Lender will, to the extent applicable, purchase that portion of outstanding Advances of the other Lenders or take such other actions as the Administrative Agent may determine to be necessary to cause the Advances and funded and unfunded participations in Letters of Credit to be held on a pro rata basis by the Lenders in accordance with their Pro Rata Shares (without giving effect to Section 2.17(a)(iv)), whereupon that Lender will cease to be a Defaulting Lender; provided that no adjustments will be made retroactively with respect to fees accrued or payments made by or on behalf of the Borrower while that Lender was a Defaulting Lender; and provided, further, that except to the extent otherwise expressly agreed by the affected parties, no change hereunder from Defaulting Lender to Lender will constitute a waiver or release of any claim of any party hereunder arising from that Lender’s having been a Defaulting Lender.

     (c) Replacement of Defaulting Lender. The Borrower shall have the right to replace a Defaulting Lender in accordance with Section 2.15.

filings necessary to protect, preserve and validly perfect such Liens have been made, taken or obtained, as the case may be, and are in full force and effect.

     Section 4.04. Enforceable Obligations. This Agreement, the Notes, and the other Credit Documents have been duly executed and delivered by the Borrower and each of the Guarantors to which any of them is a party. Each Credit Document is (or upon execution will be) the legal, valid, and binding obligation of the Borrower and each of the Guarantors enforceable against the Borrower and each of the Guarantors in accordance with its terms, except for the Third Party Consent Limitation with respect to real property interests to which such limitation is applicable and except as such enforceability may be limited by any applicable bankruptcy, insolvency, reorganization, moratorium, or similar law affecting creditors’ rights generally and general equitable principles (whether considered in a proceeding in equity or at law).

     Section 4.05. Financial Statements. The Borrower has delivered to the Administrative Agent and the Lenders copies of the Financial Statements, and the Financial Statements are accurate and complete in all material respects and present fairly the consolidated financial condition of the Limited Partner and its consolidated Subsidiaries as of their respective dates and for their respective periods in accordance with GAAP. As of the date of the Financial Statements, there were no material contingent obligations, liabilities for taxes, unusual forward or long term commitments, or unrealized or anticipated losses of the Borrower or any of its Subsidiaries, except for the Third Party Consent Limitation with respect to real property interests to which such limitation is applicable and except as disclosed therein and adequate reserves for such items have been made in accordance with GAAP. All projections, estimates, and pro forma financial information furnished by the Borrower were prepared on the basis of assumptions, data, information, tests, or conditions believed to be reasonable at the time such projections, estimates, and pro forma financial information were furnished. Since the date of the Financial Statements, no Material Adverse Effect has occurred, and no event or circumstance that could reasonably be expected to cause a Material Adverse Effect has occurred.

     Section 4.06. True and Complete Disclosure. All factual information heretofore or contemporaneously furnished by or on behalf of the Borrower, any of its Subsidiaries or any of the Partners in writing to the Administrative Agent and the Lenders for purposes of or in connection with this Agreement, any other Credit Document, or any transaction contemplated hereby or thereby is, and all other such factual information (taken as a whole) hereafter furnished by or on behalf of the Borrower, any of its Subsidiaries or any of the Partners in writing to the Administrative Agent and the Lenders will be, true and accurate in all material respects on the date as of which such information is dated or certified and not incomplete by omitting to state any material fact necessary to make such information (taken as a whole) not misleading at such time.

     Section 4.07. Litigation. Except as set forth on Schedule 4.07, there is no pending or, to the best knowledge of the Borrower or any of its Subsidiaries, threatened action or proceeding against the Borrower, any of its Subsidiaries or any of the Partners before any court, Governmental Authority or arbitrator, including, without limitation, the FERC or any equivalent state regulatory agency, which could reasonably, individually or in the aggregate, be expected to have a Material Adverse Effect or which purports to affect the legality, validity, binding effect or enforceability of this Agreement, the Notes, or any other Credit Document. Additionally, there is no pending or, to the knowledge of any Responsible Officer, threatened action or proceeding instituted against the Borrower, any of its Subsidiaries, or any Partner which seeks to adjudicate the Borrower, any of its Subsidiaries, or any Partner as bankrupt or insolvent, or seeking liquidation, winding up, reorganization, arrangement, adjustment, protection, relief, or composition of it or its debts under any law relating to bankruptcy, insolvency or reorganization or

L.P. Credit Agreement

relief of debtors, or seeking the entry of an order for relief or the appointment of a receiver, trustee or other similar official for it or for any substantial part of its Property other than a threatened action or involuntary proceeding that is not an Event of Default pursuant to Section 7.01(e).

     Section 4.08. Use of Proceeds. The proceeds of the Borrowings will be used by the Borrower for (i) working capital purposes of the Borrower, any Guarantor and their Subsidiaries, (ii) Investments, Acquisitions and the development of new projects, including, without limitation, any Capital Expansion Projects, (iii) general corporate purposes of the Borrower, any Guarantor and their Subsidiaries including, without limitation, the making of capital expenditures, (iv) to refinance Debt existing under the Prior Credit Agreement, (v) payment of the fees and expenses incurred in connection with the refinancing of the Debt existing under the Prior Credit Agreement, (vi) the making of Distribution Payments in compliance with Section 6.05 and (vii) the repayment or repurchase of Debt, including, without limitation, all or a portion of the 6.25% Senior Notes, in compliance with Section 6.05 and Section 6.18.

     Section 4.09. Investment Company Act. None of the General Partner, the Limited Partner, the Borrower or any of its Subsidiaries is an “investment company” or a company “controlled” by an “investment company” within the meaning of the Investment Company Act of 1940, as amended.

     Section 4.10. Taxes. All federal, and material state, local and foreign tax returns, reports and statements required to be filed (after giving effect to any extension granted in the time for filing) by the Borrower or any member of the Controlled Group (hereafter collectively called the “Tax Group”) have been filed with the appropriate Governmental Authority in all jurisdictions in which such returns, reports, and statements are required to be filed, and all taxes (which are material in amount) and other impositions due and payable have been timely paid prior to the date on which any fine, penalty, interest, late charge or loss may be added thereto for non-payment thereof except (a) where contested in good faith and by appropriate proceedings or (b) to the extent the failure to pay such, individually or in the aggregate, could not reasonably be expected to have a Material Adverse Effect. Neither the Borrower nor any member of the Tax Group has given, or been requested to give, a waiver of the statute of limitations relating to the payment of any federal, state, local or foreign taxes or other impositions. Proper and accurate amounts have been withheld by the Borrower and all other members of the Tax Group from their employees for all periods to comply in all material respects with the tax, social security and unemployment withholding provisions of applicable federal, state, local and foreign law. Timely payment of all sales and use taxes required by applicable law have been made by the Borrower and all other members of the Tax Group, except to the extent that the failure to pay such, individually or in the aggregate, could not reasonably be expected to have a Material Adverse Effect.

     Section 4.11. Pension Plans; ERISA. All Plans are in compliance in all material respects with all applicable provisions of ERISA. No Termination Event has occurred with respect to any Plan, and each Plan has complied with and been administered in all material respects in accordance with applicable provisions of ERISA and the Code. No “accumulated funding deficiency” (as defined in Section 302 of ERISA) has occurred and there has been no excise tax imposed under Section 4971 of the Code. No Reportable Event has occurred with respect to any Multiemployer Plan, and each Multiemployer Plan has complied with and been administered in all material respects with applicable provisions of ERISA and the Code. Neither the Borrower nor any member of the Controlled Group has had a complete or partial withdrawal from any Multiemployer Plan for which there is any withdrawal liability. As of the most recent valuation date applicable thereto, neither the Borrower nor any member of the Controlled Group would become subject to any liability under ERISA if the Borrower or any member of the Controlled Group has received notice that any Multiemployer Plan is insolvent or in reorganization. Based upon GAAP existing as of the date of this Agreement and current factual circumstances, the Borrower has no reason to believe that the annual cost during the term of this Agreement to the Borrower or any member of the Controlled Group for post-retirement benefits to be provided to the current and former employees

Holly Energy Partners -Operating
L.P. Credit Agreement

of the Borrower or any member of the Controlled Group under Plans that are welfare benefit plans (as defined in Section 3(1) of ERISA) could, in the aggregate, reasonably be expected to cause a Material Adverse Change.

     Section 4.12. Insurance. The Borrower and its Subsidiaries carry the insurance required to be carried under Section 5.02 of this Agreement.

     Section 4.13. No Burdensome Restrictions; No Defaults. None of the Borrower, any of its Subsidiaries, the General Partner, or the Limited Partner is a party to any indenture, loan or credit agreement or any lease or other agreement or instrument or subject to any charter or partnership restriction or provision of any Legal Requirement which could reasonably, individually or in the aggregate, be expected to have a Material Adverse Effect or which could affect the legality, validity, binding effect or enforceability of this Agreement, the Notes, or any other Credit Document. Except as set forth on Schedule 4.13, none of the Borrower, any of its Subsidiaries, the General Partner, or the Limited Partner is in default under or with respect to any Material Contract to which the Borrower, any of its Subsidiaries, the General Partner, or the Limited Partner is a party.

     Section 4.14. Environmental Condition. Except for matters that, individually or in the aggregate, (i) do not materially interfere with the ordinary conduct of Business, (ii) do not materially detract from the value or the use of the portion of the Pipeline Systems affected thereby and (iii) could not reasonably be expected to have a Material Adverse Effect:

     (c) Certain Actions. Without limiting the foregoing, (i) all necessary notices have been properly filed, and no further action is required under current Environmental Law as to each Response or other restoration or remedial project taken by the Borrower or any of its Subsidiaries on any of their presently or formerly owned or operated real property and (ii) there is no material present and future liability, if any, of the Borrower and its Subsidiaries which could reasonably be expected to arise in connection with requirements under Environmental Laws.

     Section 4.15. Permits, Licenses, etc. The Borrower and each of its Subsidiaries possesses all authorizations, permits, licenses, patents, patent rights or licenses, trademarks, trademark rights, trade names rights and copyrights which are necessary to conduct the Business. Each of the Borrower and its Subsidiaries manages and operates its business in all material respects in accordance with all applicable Legal Requirements, except where such failure to comply, either individually or in the aggregate, could not reasonably have a Material Adverse Effect. No violations exist or have been recorded in respect of such authorizations, permits, licenses, patents, patent rights or licenses, trademarks, trademark rights, trade names rights and copyrights, including, without limitation, any known conflict with the valid trademarks, trade names, copyrights or licenses of others which could, individually or in the aggregate, have a Material Adverse Effect.

     Section 4.16. Security Interests.

On the date of this Agreement, all governmental actions and all other filings, recordings, registrations, third party consents and other actions which are necessary to create and perfect the Liens provided for in the Security Documents will have been made, obtained and taken in all relevant jurisdictions, or satisfactory arrangements will have been made for all governmental actions and all other filings, recordings, registrations, third party consents, and other actions which are necessary to create and perfect the Liens provided for in the Security Documents to be made, obtained, or taken in all relevant jurisdictions. Upon the filing of the Security Documents, each of the Security Documents creates, as security for the Obligations purported to be secured thereby, an Acceptable Security Interest.

     Section 4.17. Title, Etc.

     (a) The Borrower and each of its Subsidiaries have good and marketable title, in all material respects, in all of their respective Property, including, without limitation, the real and personal property described in each of the Mortgages, as is necessary to operate the Business as reflected in the Financial Statements, and none of such Property is subject to any Lien, except Permitted Liens.

     (b) The Pipeline Systems are covered by recorded fee deeds, rights of way, easements, leases, subleases, servitudes, permits, licenses, or other instruments (collectively, “rights of way”) in favor of the Borrower or its Subsidiaries (or their predecessors in interest) and their respective successors and assigns, except where the failure of the Pipeline Systems to be so covered, individually or in the aggregate, (i) does not materially interfere with the ordinary conduct of Business, (ii) does not materially detract from the value or the use of the portion of the Pipeline Systems which are not covered and (ii) could not reasonably be expected to have a Material Adverse Effect. The rights of way establish a contiguous and continuous right of way for the Pipeline Systems and grant the Borrower or its Subsidiaries (or their predecessors in interest) the right to construct, operate, and maintain the Pipeline Systems in, over, under, or across the land covered thereby in the same way that a prudent owner and operator would inspect, operate, repair, and maintain similar assets and in the same way as the Borrower has inspected, operated, repaired, and maintained the Pipeline Systems as reflected in the Financial Statements; provided, however, (A) some of the rights of way granted to the Borrower or its Subsidiaries (or their predecessors in interest) by private parties and Governmental Authorities are revocable at the right of the applicable grantor, (B) some of the rights of way cross properties that are subject to liens in favor of third parties that have not been subordinated to the rights of way; and (C) some rights of way are subject to certain defects, limitations and restrictions; provided, further, none of the limitations, defects,

and restrictions described in clauses (A), (B) and (C) above, individually or in the aggregate, (x) materially interfere with the ordinary conduct of Business, (y) materially detract from the value or the use of the portion of the Pipeline Systems which are covered or (z) could reasonably be expected to have a Material Adverse Effect.

     (c) The Terminals are covered by fee deeds, real property leases, or other instruments (collectively “deeds”) in favor of the Borrower or its Subsidiaries (or their predecessors in interest) and their respective successors and assigns. The deeds grant the Borrower or its Subsidiaries (or their predecessors in interest) the right to construct, operate, and maintain the Terminals in, over, under, and across the land covered thereby in the same way that a prudent owner and operator would inspect, operate, repair, and maintain similar assets and in the same way as the Borrower has inspected, operated, repaired, and maintained the Terminals as reflected in the Financial Statements.

     (d) There has been no and there is not presently any occurrence of any (i) breach or event of default on the part of the Borrower or any of its Subsidiaries with respect to any right of way or deed, (ii) to the knowledge of the Borrower or any of its Subsidiaries, breach or event of default on the part of any other party to any right of way or deed, or (iii) event that, with the giving of notice or lapse of time or both, would constitute such breach or event of default on the part of the Borrower or any of its Subsidiaries with respect to any right of way or deed or, to the knowledge of the Borrower or any of its Subsidiaries, on the part of any other party thereto, in each case, to the extent any such breach or default, individually or in the aggregate, (A) materially interferes with the ordinary conduct of Business, (B) materially detracts from the value or the use of the portion of the Pipeline Systems covered thereby or (C) could reasonably be expected to have a Material Adverse Effect. The rights of way and deeds (to the extent applicable) are in full force and effect in all material respects and are valid and enforceable against the parties thereto in accordance with their terms (subject to the effect of any applicable bankruptcy, reorganization, insolvency, moratorium, fraudulent transfer, fraudulent conveyance or similar laws effecting creditors’ rights generally and subject, as to enforceability to the effect of general principles of equity) and all rental and other payments due thereunder by the Borrower, its Subsidiaries, and their predecessors in interest have been duly paid in accordance with the terms of the deeds and rights of way (as such terms are defined in this Section 4.17) except to the extent that a failure to do so, individually or in the aggregate, (x) does not materially interfere with the ordinary conduct of Business, (y) does not materially detract from the value or the use of the portion of the Pipeline Systems covered thereby and (z) could not reasonably be expected to have a Material Adverse Effect.

     (e) The Pipeline Systems are located within the confines of the rights of way and do not encroach upon any adjoining property in any one or more material respects. The Terminals are located within the boundaries of the property affected by the deeds, leases or other instruments to the Borrower or its Subsidiaries and do not encroach upon any adjoining property in any one or more material respects. The buildings and improvements owned or leased by the Borrower and its Subsidiaries, and the operation and maintenance thereof, do not (i) contravene any applicable zoning or building law or ordinance or other administrative regulation or (ii) violate any applicable restrictive covenant or any Legal Requirement, the contravention or violation of which would materially affect the use of the property subject thereto.

     (f) The material Properties used or to be used in the Business or the continuing operations of the Borrower and each of its Subsidiaries are in good repair, working order, and condition, normal wear and tear excepted. Neither the Business nor the Properties of the Borrower or any of its Subsidiaries has been affected in any material and adverse manner as a result of any fire, explosion, earthquake, flood, drought, windstorm, accident, strike or other labor disturbance, embargo, requisition or taking of Property

or cancellation of contracts, permits or concessions by a Governmental Authority, riot, activities of armed forces or acts of God or of any public enemy.

     (g) No eminent domain proceeding or taking has been commenced or, to the knowledge of the Borrower or any of its Subsidiaries, is contemplated with respect to all or any portion of the Pipeline Systems or the Terminals except for that which, individually or in the aggregate, could not reasonably be expected to have a Material Adverse Effect.

     (h) No portion of the Pipeline Systems or the Terminals has, since the date of this Agreement, suffered any material damage by fire or other casualty loss that has not heretofore been repaired and restored. No portion of the Terminals is located in a special flood hazard area as designated by any Governmental Authority.

     Section 4.18. State and Federal Regulation.

     (a) The interstate common carrier pipeline operations comprising a portion of the Pipeline Systems (the “Borrower Interstate Pipelines”) are subject to rate regulation by the FERC under the Interstate Commerce Act and the Energy Policy Act. With respect to that certain portion of the Borrower Interstate Pipelines that is located between Artesia, New Mexico and El Paso, Texas, (i) the rates on file with the FERC are just and reasonable pursuant to the Energy Policy Act and (ii) to the knowledge of the Borrower, no provision of the tariff containing such rates is unduly discriminatory or preferential. Except as set forth on Schedule 4.18(a) or which could not reasonably be expected to cause a Material Adverse Effect, neither the Borrower, the Parent, any of the Borrower’s Subsidiaries, nor any other Person that now owns or has owned an interest in any of the Borrower Interstate Pipelines has been or is the subject of a complaint, investigation or other proceeding regarding their respective rates or practices with respect to the Borrower Interstate Pipelines. No such complaint, petition, or other filing with the FERC, individually or in the aggregate, could result, if adversely determined to the position or interest of Borrower or its applicable Subsidiaries, in a Material Adverse Effect.

     (b) With respect to those certain intrastate common carrier pipeline operations that comprise a portion of the Pipeline Systems, as of the Effective Date, such pipeline operations in the State of Texas (the “Texas Intrastate Pipelines”) are subject to regulation by the Railroad Commission of Texas. Each of the Borrower and its Subsidiaries which owns pipelines and conducts pipeline operations in the State of Texas has followed prudent practice in the refined products transportation and distribution industries, as applicable, regarding the setting of rates for services provided and the implementation of such rates. To the Borrower’s knowledge, the rates charged by Borrower and its Subsidiaries with respect to the Texas Intrastate Pipelines, as reflected in the Financial Statements, provide no more than a fair return on the aggregate value of the property used to render services on the Texas Intrastate Pipelines, and to the Borrower’s knowledge, neither Borrower nor any of its Subsidiaries uses, charges, imposes, or implements, or has previously done any of the foregoing in a discriminatory way. As of the Effective Date, the Borrower’s and its Subsidiaries’ pipeline operations in the State of Idaho and in the State of New Mexico do not constitute intrastate common carrier pipeline operations and are not subject to regulation by the Idaho Public Utilities Commission or the New Mexico Public Regulation Commission. Except as set forth on Schedule 4.18(b), neither the Borrower, the Parent, any of the Borrower’s Subsidiaries, nor any other party that now owns or has owned an interest in any of the Texas Intrastate Pipelines has been or is the subject of a complaint, investigation or other proceeding regarding their respective rates or practices with respect to the Texas Intrastate Pipelines.

Moreover, the Administrative Agent as the secured party may take such independent action in connection therewith as it may in its reasonable discretion deem proper, including the right to employ independent counsel and to intervene in any suit affecting the Collateral.

ARTICLE VIII

THE ADMINISTRATIVE AGENT AND THE ISSUING BANKS

     Section 8.01. Appointment and Authorization of Administrative Agent.

     (a) Each Lender hereby irrevocably (subject to Section 8.10) appoints, designates and authorizes the Administrative Agent to take such action on its behalf under the provisions of this Agreement and each other Credit Document and to exercise such powers and perform such duties as are expressly delegated to it by the terms of this Agreement or any other Credit Document, together with such powers as are reasonably incidental thereto. Notwithstanding any provision to the contrary contained elsewhere herein or in any other Credit Document, the Administrative Agent shall not have any duties or responsibilities, except those expressly set forth herein, nor shall the Administrative Agent have or be deemed to have any fiduciary relationship with any Lender or participant, and no implied covenants, functions, responsibilities, duties, obligations or liabilities shall be read into this Agreement or any other Credit Document or otherwise exist against the Administrative Agent. Without limiting the generality of the foregoing sentence, the use of the term “agent” herein and in the other Credit Documents with reference to the Administrative Agent, any syndication agent or documentation agent is not intended to connote any fiduciary or other implied (or express) obligations arising under agency doctrine of any

Holly Energy Partners -Operating
L.P. Credit Agreement

applicable law. Instead, such term is used merely as a matter of market custom, and is intended to create or reflect only an administrative relationship between independent contracting parties.

     (b) Each Issuing Bank shall act on behalf of the Lenders with respect to any Letters of Credit issued by it and the documents associated therewith until such time (and except for so long) as the Administrative Agent may agree at the request of the Majority Lenders to act for such Issuing Bank with respect thereto; provided, however, that each Issuing Bank shall have all of the benefits and immunities (i) provided to the Administrative Agent in this Article VIII with respect to any acts taken or omissions suffered by an Issuing Bank in connection with Letters of Credit issued by it or proposed to be issued by it and the application and agreements for letters of credit pertaining to the Letters of Credit as fully as if the term “Administrative Agent” as used in this Article VIII included each Issuing Bank with respect to such acts or omissions, and (ii) as additionally provided herein with respect to each Issuing Bank.

     Section 8.02. Delegation of Duties. The Administrative Agent may execute any of its duties under this Agreement or any other Credit Document by or through agents, sub-agents, employees or attorneys-in-fact and shall be entitled to advice of counsel and other consultants or experts concerning all matters pertaining to such duties. Administrative Agent shall not be responsible for the negligence or misconduct of any agent or attorney-in-fact that it selects in the absence of gross negligence, bad faith, or willful misconduct.

     Section 8.03. Default; Collateral.

     (a) Upon the occurrence and continuance of a Default or Event of Default, the Lenders agree to promptly confer in order that Majority Lenders or all Lenders, as the case may be, may agree upon a course of action for the enforcement of the rights of the Lenders; and the Administrative Agent shall be entitled to refrain from taking any action (without incurring any liability to any Person for so refraining) unless and until the Administrative Agent shall have received instructions from Majority Lenders or all Lenders, as the case may be. All rights of action under the Credit Documents and all right to the Collateral, if any, hereunder may be enforced by the Administrative Agent and any suit or proceeding instituted by the Administrative Agent in furtherance of such enforcement shall be brought in its name as the Administrative Agent without the necessity of joining as plaintiffs or defendants any other Lender, and the recovery of any judgment shall be for the benefit of the Lenders (and, with respect to Lender Hedging Agreements and Banking Services, Affiliates, if applicable) subject to the expenses of the Administrative Agent. In actions with respect to any property of the Borrower or any Guarantor, the Administrative Agent is acting for the ratable benefit of each Lender (and, with respect to Lender Hedging Agreements and Banking Services, Affiliates, if applicable). Any and all agreements to subordinate (whether made heretofore or hereafter) other indebtedness or obligations of Borrower to the Obligations shall be construed as being for the ratable benefit of each Lender (and, with respect to Lender Hedging Agreements and Banking Services, Affiliates, if applicable).

     (b) Each Lender authorizes and directs the Administrative Agent to enter into the Security Documents on behalf of and for the benefit of the Lenders (and, with respect to Lender Hedging Agreements and Banking Services, Affiliates, if applicable)(or if previously entered into, hereby ratifies the Administrative Agent’s (or any predecessor administrative agent’s) previously entering into such agreements and Security Documents).

     (c) Except to the extent unanimity (or other percentage set forth in Section 9.01) is required hereunder, each Lender agrees that any action taken by the Majority Lenders in accordance with the provisions of the Credit Documents, and the exercise by the Majority Lenders of the power set forth herein or therein, together with such other powers as are reasonably incidental thereto, shall be authorized

L.P. Credit Agreement

and binding upon all of the Lenders and Affiliates of Lenders (with respect to Banking Service Obligations and Lender Hedging Agreements).

     (d) The Administrative Agent is hereby authorized on behalf of the Lenders, without the necessity of any notice to or further consent from any Lender, from time to time to take any action with respect to any Collateral or Security Documents which may be necessary to perfect and maintain perfected the Liens upon the Collateral granted pursuant to the Security Documents.

     (e) The Administrative Agent shall not have any obligation whatsoever to any Lender or to any other Person (and the Predecessor Administrative Agent shall not have any obligation whatsoever to the Administrative Agent, any other Lender or to any other Person) to assure that the Collateral exists or is owned by the Person purporting to own it or is cared for, protected, or insured or has been encumbered or that the Liens granted to the Administrative Agent (or any predecessor administrative agent) herein or pursuant thereto have been properly or sufficiently or lawfully created, perfected, protected, or enforced, or are entitled to any particular priority, or to exercise at all or in any particular manner or under any duty of care, disclosure, or fidelity, or to continue exercising, any of the rights granted or available to the Administrative Agent in this Section 8.03 or in any of the Security Documents; it being understood and agreed that in respect of the Collateral, or any act, omission, or event related thereto, the Administrative Agent may act in any manner it may deem appropriate, in its sole discretion, given the Administrative Agent’s own interest in the Collateral as one of the Lenders and that the Administrative Agent shall have no duty or liability whatsoever to any Lender (and, with respect to Lender Hedging Agreements and banking services, Affiliates), other than to act without gross negligence, bad faith, or willful misconduct.

     (f) The Lenders hereby irrevocably authorize the Administrative Agent, at its option and in its discretion, to (i) deliver instruments of assurance confirming the non-existence of any Lien under the Credit Documents with respect to assets of a Person described in Section 5.11 that are excluded from the Collateral and (ii) release any Lien granted to or held by the Administrative Agent upon any Collateral: (A) constituting Property in which neither Borrower nor any Guarantor owned an interest at the time the Lien was granted or at any time thereafter; (B) constituting property leased to the Borrower or a Guarantor under a lease which has expired or been terminated in a transaction permitted under the Credit Documents or is about to expire and which has not been, and is not intended by the Borrower or such Guarantor to be, renewed; (C) consisting of an instrument or other possessory collateral evidencing Debt or other obligations pledged to the Administrative Agent (for the benefit of the Lenders), if the Debt or obligations evidenced thereby has been paid in full or otherwise superseded. In addition, the Lenders irrevocably authorize the Administrative Agent to release Liens upon Collateral as contemplated herein, or if approved, authorized, or ratified in writing by the requisite Lenders; (D) Property permitted to be sold pursuant to Section 6.04; or (E) Property permitted to be invested pursuant to Section 6.06. Upon request by the Administrative Agent at any time, the Lenders will confirm in writing the Administrative Agent’s authority to release particular types or items of Collateral pursuant to this Section 8.03.

     (g) In furtherance of the authorizations set forth in this Section 8.03, each Lender hereby irrevocably appoints the Administrative Agent its attorney-in-fact, with full power of substitution, for and on behalf of and in the name of each such Lender (i) to enter into Security Documents (including, without limitation, any appointments of substitute trustees under any Security Documents), (ii) to take action with respect to the Collateral and Security Documents to perfect, maintain, and preserve Lenders’ Liens, and (iii) to execute instruments of release or to take other action necessary to release Liens upon any Collateral to the extent authorized in paragraph (f) hereof. This power of attorney shall be liberally, not restrictively, construed so as to give the greatest latitude to the Administrative Agent’s power, as attorney-in-fact, relative to the Collateral matters described in this Section 8.03. The powers and

Holly Energy Partners -Operating
L.P. Credit Agreement

authorities herein conferred on the Administrative Agent may be exercised by the Administrative Agent through any Person who, at the time of the execution of a particular instrument, is an officer of the Administrative Agent (or any Person acting on behalf of the Administrative Agent pursuant to a valid power of attorney). The power of attorney conferred by this Section 8.03(g) to the Administrative Agent is granted for valuable consideration and is coupled with an interest and is irrevocable so long as the Obligations, or any part thereof, shall remain unpaid or the Lenders are obligated to make any Advance or issue any Letter of Credit under the Credit Documents.

     Section 8.04. Liability of Administrative Agent. NO AGENT-RELATED PERSON SHALL (A) BE LIABLE FOR ANY ACTION TAKEN OR OMITTED TO BE TAKEN BY ANY OF THEM UNDER OR IN CONNECTION WITH THIS AGREEMENT OR ANY OTHER CREDIT DOCUMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY (EXCEPT FOR ITS OWN GROSS NEGLIGENCE, BAD FAITH, OR WILLFUL MISCONDUCT IN CONNECTION WITH ITS DUTIES EXPRESSLY SET FORTH HEREIN), or (b) be responsible in any manner to any Lender or participant for any recital, statement, representation or warranty made by Borrower or any Guarantor or any officer thereof, contained herein or in any other Credit Document, or in any certificate, report, statement or other document referred to or provided for in, or received by Administrative Agent under or in connection with, this Agreement or any other Credit Document, or the validity, effectiveness, genuineness, enforceability or sufficiency of this Agreement or any other Credit Document, or for the creation, perfection or priority of any Liens purported to be created by any of the Credit Documents, or the validity, genuineness, enforceability, existence, value or sufficiency of any collateral security, or to make any inquiry respecting the performance by the Borrower of its obligations hereunder or under any other Credit Document, or for any failure of Borrower or any Guarantor or any other party to any Credit Document to perform its obligations hereunder or thereunder. No Agent-Related Person shall be under any obligation to any Lender or participant to ascertain or to inquire as to the observance or performance of any of the agreements contained in, or conditions of, this Agreement or any other Credit Document, or to inspect the properties, books or records of the Borrower or any Guarantor or any Affiliate thereof.

     Section 8.05. Reliance by Administrative Agent.

     (a) The Administrative Agent shall be entitled to rely, and shall be fully protected in relying, upon any writing, communication, signature, resolution, representation, notice, consent, certificate, affidavit, letter, telegram, facsimile, electronic mail, telex or telephone message, statement or other document or conversation believed by it to be genuine and correct and to have been signed, sent or made by the proper Person or Persons, and upon advice and statements of legal counsel (including counsel to the Borrower or any Guarantor), independent accountants and other experts selected by the Administrative Agent. The Administrative Agent shall be fully justified in failing or refusing to take any action under any Credit Document unless it shall first receive such advice or concurrence of the requisite Majority Lenders as it deems appropriate and, if it so requests, it shall first be indemnified to its satisfaction by the Lenders against any and all liability and expense which may be incurred by it by reason of taking or continuing to take any such action. The Administrative Agent shall in all cases be fully protected in acting, or in refraining from acting, under this Agreement or any other Credit Document in accordance with a request or consent of the requisite Majority Lenders or all the Lenders, if required hereunder, and such request and any action taken or failure to act pursuant thereto shall be binding upon all the Lenders and participants. Where this Agreement expressly permits or prohibits an action unless the requisite Majority Lenders otherwise determine, the Administrative Agent shall, and in all other instances, the Administrative Agent may, but shall not be required to, initiate any solicitation for the consent or a vote of the requisite Lenders.

     (b) For purposes of determining compliance with the conditions specified in Section 4.01, each Lender that has funded its Pro Rata Share of the initial Advance on the Effective Date (or, if there is

Holly Energy Partners -Operating
L.P. Credit Agreement

no Advance made on such date, each Lender other than Lenders who gave written objection to the Administrative Agent prior to such date) shall be deemed to have consented to, approved or accepted or to be satisfied with, each document or other matter either sent by the Administrative Agent to such Lender (or otherwise made available for such Lender on SyndTrak Online, DXSyndicate™ or any similar website) for consent, approval, acceptance or satisfaction, or required hereunder to be consented to or approved by or acceptable or satisfactory to a Lender.

     Section 8.06. Notice of Default. The Administrative Agent shall not be deemed to have knowledge or notice of the occurrence of any Default or Event of Default, except with respect to defaults in the payment of principal, interest and fees required to be paid to the Administrative Agent for the account of the Lenders, unless the Administrative Agent shall have received written notice from a Lender or the Borrower referring to this Agreement, describing such Default or Event of Default and stating that such notice is a “notice of default.” The Administrative Agent will notify the Lenders of its receipt of any such notice. The Administrative Agent shall take such action with respect to such Default or Event of Default as may be directed by the Majority Lenders in accordance with this Article VIII; provided, however, that unless and until the Administrative Agent has received any such direction, the Administrative Agent may (but shall not be obligated to) take such action, or refrain from taking such action, with respect to such Default or Event of Default as it shall deem advisable or in the best interest of the Lenders.

     Section 8.07. Credit Decision; Disclosure of Information by Administrative Agent. Each Lender acknowledges that no Agent-Related Person has made any representation or warranty to it, and that no act by the Administrative Agent hereinafter taken, including any consent to and acceptance of any assignment or review of the affairs of the Borrower or any Guarantor or any Affiliate thereof, shall be deemed to constitute any representation or warranty by any Agent-Related Person to any Lender as to any matter, including whether Agent-Related Persons have disclosed material information in their possession. Each Lender represents to the Administrative Agent that it has, independently and without reliance upon any Agent-Related Person and based on such documents and information as it has deemed appropriate, made its own appraisal of and investigation into the business, prospects, operations, property, financial and other condition and creditworthiness of the Borrower, any Guarantor and their respective Subsidiaries, and all applicable bank or other regulatory laws relating to the transactions contemplated hereby, and made its own decision to enter into this Agreement and to extend credit to the Borrower hereunder. Each Lender also represents that it will, independently and without reliance upon any Agent-Related Person and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit analysis, appraisals and decisions in taking or not taking action under this Agreement and the other Credit Documents, and to make such investigations as it deems necessary to inform itself as to the business, prospects, operations, property, financial and other condition and creditworthiness of the Borrower and the other Loan Parties. In this regard, each Lender acknowledges that Thompson & Knight LLP is acting in this transaction as counsel to the Administrative Agent. Each other party hereto will consult with its own legal counsel to the extent that it deems necessary in connection with the Credit Documents and the matters contemplated therein. Except for notices, reports and other documents expressly required to be furnished to the Lenders by the Administrative Agent herein, the Administrative Agent shall not have any duty or responsibility to provide any Lender with any credit or other information concerning the business, prospects, operations, property, financial and other condition or creditworthiness of any of the Loan Parties or any of their respective Affiliates which may come into the possession of any Agent-Related Person.

     Section 8.08. Indemnification of Agents. Whether or not the transactions contemplated hereby are consummated, the Lenders shall indemnify upon demand each Agent-Related Person (to the extent not reimbursed by or on behalf of the

Holly Energy Partners -Operating
L.P. Credit Agreement

Borrower and without limiting the obligation of Borrower to do so), in accordance with their respective Pro Rata Shares, and hold harmless each Agent-Related Person from and against any and all indemnified liabilities incurred by it (including such Agent-Related Person’s own negligence); provided, however, that no Lender shall be liable for the payment to any Agent-Related Person of any portion of such indemnified liabilities resulting from such Person’s gross negligence, bad faith, or willful misconduct; provided, however, that no action taken in accordance with the directions of the Majority Lenders shall be deemed to constitute gross negligence, bad faith, or willful misconduct for purposes of this Section 8.08. Without limitation of the foregoing, each Lender shall reimburse the Administrative Agent upon demand for its ratable share of any costs or reasonable out-of-pocket expenses (including counsel fees) incurred by the Administrative Agent in connection with the preparation, execution, delivery, administration, modification, amendment or enforcement (whether through negotiations, legal proceedings or otherwise) of, or legal advice in respect of rights or responsibilities under, this Agreement, any other Credit Document, or any document contemplated by or referred to herein, to the extent that the Administrative Agent is not reimbursed for such expenses by or on behalf of the Borrower and without limiting the obligation of Borrower to do so. The undertaking in this Section 8.08 shall survive termination of the Commitments, the payment of all Obligations hereunder and the resignation or replacement of the Administrative Agent.

     Section 8.09. Administrative Agent in its Individual Capacity. Wells Fargo and its Affiliates may make loans to, accept deposits from, acquire equity interests in and generally engage in any kind of banking, trust, financial advisory, underwriting or other business with the Borrower and its Affiliates as though Wells Fargo were not the Administrative Agent or an Issuing Bank hereunder and without notice to or consent of the Lenders. The Lenders acknowledge that, pursuant to such activities, Wells Fargo or its Affiliates may receive information regarding the Borrower or its Affiliates (including information that may be subject to confidentiality obligations in favor of Borrower or such Affiliate) and acknowledge that the Administrative Agent shall be under no obligation to provide such information to them. With respect to its Advances, Wells Fargo shall have the same rights and powers under this Agreement as any other Lender and may exercise such rights and powers as though it were not the Administrative Agent or an Issuing Bank, and the terms “Lender” and “Lenders” include Wells Fargo in its individual capacity.

     Section 8.10. Successor Administrative Agent and Issuing Bank. The Administrative Agent or an Issuing Bank may resign at any time upon 30 days’ notice to the Lenders with a copy of such notice to the Borrower. If the Administrative Agent or Issuing Bank resigns under this Agreement, the Majority Lenders shall appoint from among the Lenders a successor administrative agent or issuing bank for the Lenders which successor administrative agent or issuing bank shall be consented to by the Borrower at all times other than during the existence of an Event of Default. If no successor administrative agent or issuing bank is appointed prior to the effective date of the resignation of the Administrative Agent or Issuing Bank, the Administrative Agent may appoint, after consulting with the Lenders and the Borrower, a successor administrative agent and/or issuing bank from among the Lenders. Upon the acceptance of its appointment as successor administrative agent and/or issuing bank hereunder, such successor administrative agent and/or issuing bank shall succeed to all the rights, powers and duties of the retiring Administrative Agent or Issuing Bank and the term “Administrative Agent” and “Issuing Bank” shall mean such successor administrative agent or issuing bank and the retiring Administrative Agent’s or Issuing Bank’s appointment, powers and duties as Administrative Agent or Issuing Bank shall be terminated. The resigning Issuing Bank shall remain the Issuing Bank with respect to any Letters of Credit outstanding on the effective date of its resignation and the provisions affecting such Issuing Bank with respect to Letters of Credit shall inure to the benefit of the resigning Issuing Bank until the termination of all such Letters of Credit. After any retiring Administrative Agent’s resignation hereunder as Administrative Agent, the provisions of this Article VIII and Sections 9.04 and 9.09 shall inure to its

L.P. Credit Agreement

benefit as to any actions taken or omitted to be taken by it while it was Administrative Agent under this Agreement. If no successor administrative agent has accepted appointment as Administrative Agent by the date which is 30 days following a retiring Administrative Agent’s notice of resignation, the retiring Administrative Agent’s resignation shall nevertheless thereupon become effective and the Lenders shall perform all of the duties of the Administrative Agent hereunder until such time, if any, as the Majority Lenders appoint a successor agent as provided for above.

     Section 8.11. Syndication Agent; Other Agents; Arrangers. None of the Lenders or other Persons identified on the facing page or signature pages of this Agreement as a “syndication agent,” as a “documentation agent,” any other type of agent (other than the Administrative Agent), “arranger,” or “bookrunner” shall have any right, power, obligation, liability, responsibility or duty under this Agreement other than those applicable to all Lenders as such. Without limiting the foregoing, none of the Lenders so identified shall have or be deemed to have any fiduciary relationship with any Lender. Each Lender acknowledges that it has not relied, and will not rely, on any of the Lenders so identified in deciding to enter into this Agreement or in taking or not taking action hereunder.

     Section 8.12. Administrative Agent May File Proof of Claim. In case of the pendency of any receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or other judicial proceeding relative to the Borrower or any Guarantor, the Administrative Agent (irrespective of whether the principal of any Advance or Letter of Credit Exposure shall then be due and payable as herein expressed or by declaration or otherwise and irrespective of whether the Administrative Agent shall have made any demand on the Borrower) shall be entitled and empowered, by intervention in such proceeding or otherwise

     (i) to file and prove a claim for the whole amount of the principal and interest owing and unpaid in respect of the Advances, Letter of Credit Exposures and all other Obligations that are owing and unpaid and to file such other documents as may be necessary or advisable in order to have the claims of the Lenders, the Issuing Banks and the Administrative Agent (including any claim for the reasonable compensation, expenses, disbursements and advances of the Lenders, the Issuing Banks and the Administrative Agent and their respective agents and counsel and all other amounts due the Lenders, the Issuing Banks and the Administrative Agent under Sections 2.06 and 9.04) allowed in such judicial proceeding; and

     (ii) to collect and receive any monies or other property payable or deliverable on any such claims and to distribute the same;

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized by each Lender and Issuing Bank to make such payments to the Administrative Agent and, in the event that the Administrative Agent shall consent to the making of such payments directly to the Lenders and Issuing Banks, to pay to the Administrative Agent any amount due for the reasonable compensation, expenses, disbursements and advances of the Administrative Agent and its agents and counsel, and any other amounts due the Administrative Agent under Sections 2.06 and 9.04.

     Nothing contained herein shall be deemed to authorize the Administrative Agent to authorize or consent to or accept or adopt on behalf of any Lender or Issuing Bank any plan of reorganization, arrangement, adjustment or composition affecting the Obligations or the rights of any Lender or to authorize the Administrative Agent to vote in respect of the claim of any Lender in any such proceeding.

     Section 8.13. Lender Hedging Agreements To the extent any Affiliate of a Lender is a party to a Swap Contract with the Borrower or any of its Subsidiaries and thereby becomes a beneficiary of the

     Section 8.14. Banking Service Obligations. To the extent any Affiliate of a Lender provides any Banking Services and thereby becomes a beneficiary of the Liens pursuant to the Security Agreements, Mortgages or any other Collateral Document, such Affiliate of a Lender shall be deemed to appoint the Administrative Agent its nominee and agent to act for and on behalf of such Affiliate in connection with the Security Agreements, Mortgages and such Security Documents and to be bound by the terms of this Article VIII, Section 9.01(j) and the last sentence of Section 2.16.

     Section 9.06. Lender Assignments and Participations.

     (a) Assignments. Any Lender may assign to another Lender or an Approved Affiliate all or any portion of its rights and obligations under this Agreement (including, without limitation, all or a portion of its Commitments, the Advances owing to it, the Notes held by it, and the participation interest in the Letter of Credit Obligations held by it) without the Borrower’s consent and without any minimum

L.P. Credit Agreement

assignment amount. Additionally, any Lender may assign to one or more banks or other entities all or any portion of its rights and obligations under this Agreement (including, without limitation, all or a portion of its Commitments, the Advances owing to it, the Notes held by it, and the participation interest in the Letter of Credit Obligations held by it); provided, however, that (i) each such assignment shall be of a constant, and not a varying, percentage of such Lender’s rights and obligations assigned under this Agreement, (ii) the amount of the Commitments, Advances, and participation interest in the Letter of Credit Obligations of such Lender being assigned pursuant to each such assignment (determined as of the date of the Assignment and Acceptance with respect to such assignment) shall be, if to an entity other than a Lender, not less than $5,000,000.00 and shall be an integral multiple of $1,000,000.00 (unless the Borrower and Administrative Agent otherwise consent), (iii) each such assignment shall be to an Eligible Assignee or an Approved Affiliate, (iv) the parties to each such assignment shall execute and deliver to the Administrative Agent, for its acceptance and recording in the Register, an Assignment and Acceptance, together with the Notes subject to such assignment, and (v) each Eligible Assignee or Approved Affiliate (other than the Eligible Assignee of the Administrative Agent) shall pay to the Administrative Agent a $3,500 administrative fee. Additionally, the consent of the Issuing Banks (such consent not to be unreasonably withheld, conditioned or delayed) shall be required for any assignment that increases the obligation of the assignee to participate in exposure under one or more Letters of Credit (whether or not then outstanding). Upon such execution, delivery, acceptance and recording, from and after the effective date specified in each Assignment and Acceptance, which effective date shall be at least three Business Days after the execution thereof, (A) the assignee thereunder shall be a party hereto for all purposes and, to the extent that rights and obligations hereunder have been assigned to it pursuant to such Assignment and Acceptance, have the rights and obligations of a Lender hereunder and (B) such Lender thereunder shall, to the extent that rights and obligations hereunder have been assigned by it pursuant to such Assignment and Acceptance, relinquish its rights and be released from its obligations under this Agreement (and, in the case of an Assignment and Acceptance covering all or the remaining portion of such Lender’s rights and obligations under this Agreement, such Lender shall cease to be a party hereto). In connection with any assignment of rights and obligations of any Defaulting Lender hereunder, no such assignment shall be effective unless and until, in addition to the other conditions thereto set forth herein, the parties to the assignment shall make such additional payments to the Administrative Agent in an aggregate amount sufficient, upon distribution thereof as appropriate (which may be outright payment, purchases by the assignee of participations or subparticipations, or other compensating actions, including funding, with the consent of the Borrower and the Administrative Agent, the applicable Pro Rata Share of Advances previously requested but not funded by the Defaulting Lender, to each of which the applicable assignee and assignor hereby irrevocably consent), to (x) pay and satisfy in full all payment liabilities then owed by such Defaulting Lender to the Administrative Agent or any Lender hereunder (and interest accrued thereon) and (y) acquire (and fund as appropriate) its full Pro Rata Share of all Advances and participations in Letters of Credit. Notwithstanding the foregoing, in the event that any assignment of rights and obligations of any Defaulting Lender hereunder shall become effective under applicable law without compliance with the provisions of this paragraph, then the assignee of such interest shall be deemed to be a Defaulting Lender for all purposes of this Agreement until such compliance occurs.

     (b) Term of Assignments. By executing and delivering an Assignment and Acceptance, the Lender thereunder and the assignee thereunder confirm to and agree with each other and the other parties hereto as follows: (i) other than as provided in such Assignment and Acceptance, such Lender makes no representation or warranty and assumes no responsibility with respect to any statements, warranties or representations made in or in connection with this Agreement or the execution, legality, validity, enforceability, genuineness, sufficiency of value of this Agreement or any other instrument or document furnished pursuant hereto; (ii) such Lender makes no representation or warranty and assumes no responsibility with respect to the financial condition of the Borrower or the Guarantors or the

performance or observance by the Borrower or the Guarantors of any of their obligations under this Agreement or any other instrument or document furnished pursuant hereto; (iii) such assignee confirms that it has received a copy of this Agreement, together with copies of the financial statements referred to in Section 4.05 and such other documents and information as it has deemed appropriate to make its own credit analysis and decision to enter into such Assignment and Acceptance; (iv) such assignee will, independently and without reliance upon the Administrative Agent, such Lender or any other Lender and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under this Agreement; (v) such assignee appoints and authorizes the Administrative Agent to take such action as agent on its behalf and to exercise such powers under this Agreement as are delegated to the Administrative Agent by the terms hereof, together with such powers as are reasonably incidental thereto; and (vi) such assignee agrees that it will perform in accordance with their terms all of the obligations which by the terms of this Agreement are required to be performed by it as a Lender.

     (c) The Register. The Administrative Agent shall maintain at its address referred to in Section 9.02 a copy of each Assignment and Acceptance delivered to and accepted by it and a register for the recordation of the names and addresses of the Lenders and the Commitments of, and principal amount of the Advances owing to, each Lender from time to time (the “Register”). In addition, the Administrative Agent shall maintain on the Register information regarding the designation, and revocation of designation, of any Lender as a Defaulting Lender. The entries in the Register shall be conclusive and binding for all purposes, absent manifest error, and the Borrower, the Administrative Agent, the Issuing Banks, and the Lenders may treat each Person whose name is recorded in the Register as a Lender hereunder for all purposes of this Agreement. The Register shall be available for inspection by the Borrower or any Lender at any reasonable time and from time to time upon reasonable prior notice.

     (d) Procedures. Upon its receipt of an Assignment and Acceptance executed by a Lender and an Eligible Assignee or an Approved Affiliate, together with the Notes subject to such assignment, the Administrative Agent shall, if such Assignment and Acceptance has been completed and is in substantially the form of the attached Exhibit A, (i) accept such Assignment and Acceptance, (ii) record the information contained therein in the Register, and (iii) give prompt notice thereof to the Borrower. Within five Business Days after its receipt of such notice, the Borrower shall execute and deliver to the Administrative Agent in exchange for the surrendered Notes (A) if such Eligible Assignee or Approved Affiliate has acquired a Commitment, a new Note to such Eligible Assignee in an amount equal to the Commitment assumed by it pursuant to such Assignment and Acceptance and (B) if such Lender has retained any Commitment hereunder, a new Note to such Lender in an amount equal to the Commitment retained by it hereunder. Such new Note or Notes shall be dated the effective date of such Assignment and Acceptance and shall otherwise be in substantially the form of the attached Exhibit A.

     (e) Participations. Each Lender may sell participations to one or more banks or other entities (other than a Defaulting Lender or Subsidiary of a Defaulting Lender) in or to all or a portion of its rights and obligations under this Agreement (including, without limitation, all or a portion of its Commitments, the Advances owing to it, its participation interest in the Letter of Credit Obligations, and the Notes held by it); provided, however, that (i) such Lender’s obligations under this Agreement (including, without limitation, its Commitments to the Borrower hereunder) shall remain unchanged, (ii) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations, (iii) such Lender shall remain the holder of any such Notes for all purposes of this Agreement, (iv) the Borrower, the Administrative Agent, and the Issuing Banks and the other Lenders shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement, and (v) such Lender shall not require the participant’s consent to any matter under this Agreement, except for change in the principal amount of the Notes, reductions in fees or interest, releasing all or substantially

The Borrower hereby agrees that participants shall have the same rights under Sections 2.10, 2.11, 2.12(b) and 9.07 as a Lender, subject to the requirements and limitations therein, including the requirements of Section 2.12(c) (it being understood that the documentation required under Section 2.12(c) shall be delivered by the participant to the Lender issuing such participation), to the extent of their respective participations, and provided that a participant shall in no event be entitled to receive any greater payment than the Lender that issued the participation would have been entitled to receive with respect to such participation.

     (f) Notwithstanding any other provision set forth in this Agreement, any Lender may at any time assign and pledge all or any portion of its Advances and its Notes to any Federal Reserve Bank as collateral security pursuant to Regulation A and any Operating Circular issued by such Federal Reserve Bank. No such assignment shall release the assigning Lender from its obligations hereunder.

     Section 9.07. Indemnification. BORROWER SHALL INDEMNIFY THE ADMINISTRATIVE AGENT, THE ARRANGERS, EACH ISSUING BANK AND EACH LENDER AND THEIR RESPECTIVE AFFILIATES, DIRECTORS, OFFICERS, EMPLOYEES AND AGENTS FROM, AND DISCHARGE, RELEASE, AND HOLD EACH OF THEM HARMLESS AGAINST, ANY AND ALL LIABILITIES, OBLIGATIONS, LOSSES, CLAIMS, EXPENSES, OR DAMAGES OF ANY KIND OR NATURE WHATSOEVER (OTHER THAN EXCLUDED TAXES AND TAXES GOVERNED BY SECTION 2.12) TO WHICH ANY OF THEM MAY BECOME SUBJECT RELATING TO OR ARISING OUT OF THIS AGREEMENT, INCLUDING ANY LIABILITIES, OBLIGATIONS, LOSSES, CLAIMS, EXPENSES, OR DAMAGES WHICH ARISE OUT OF OR RESULT FROM (I) ANY ACTUAL OR PROPOSED USE BY THE BORROWER OR ANY AFFILIATE OF THE BORROWER OF THE PROCEEDS OF THE ADVANCES OR ANY LETTER OF CREDIT, (II) ANY BREACH BY THE BORROWER OR ANY AFFILIATE OF THE BORROWER OF ANY PROVISION OF THIS AGREEMENT OR ANY OTHER CREDIT DOCUMENT, (III) ANY INVESTIGATION, LITIGATION OR OTHER PROCEEDING (INCLUDING ANY THREATENED INVESTIGATION OR PROCEEDING) RELATING TO THE FOREGOING, (IV) ANY ENVIRONMENTAL CLAIM OR REQUIREMENT OF ENVIRONMENTAL LAWS CONCERNING OR RELATING TO THE PRESENT OR PREVIOUSLY-OWNED OR OPERATED PROPERTIES OF THE BORROWER OR ANY AFFILIATE OF THE BORROWER OR THE OPERATIONS OR BUSINESS OF THE BORROWER OR ANY AFFILIATE OF THE BORROWER, OR (V) ANY ENVIRONMENTAL CLAIM OR REQUIREMENT OF ENVIRONMENTAL LAWS CONCERNING OR RELATED TO THE BORROWER’S OR ANY BORROWER AFFILIATE’S PROPERTIES AND THE BORROWER SHALL REIMBURSE THE ADMINISTRATIVE AGENT, THE ARRANGERS, EACH ISSUING BANK AND EACH LENDER AND THEIR RESPECTIVE AFFILIATES, DIRECTORS, OFFICERS, EMPLOYEES AND AGENTS, UPON DEMAND FOR ANY REASONABLE OUT-OF-POCKET EXPENSES (INCLUDING REASONABLE OUTSIDE LEGAL FEES AND SETTLEMENT COSTS) INCURRED IN CONNECTION WITH ANY SUCH INVESTIGATION, LITIGATION OR OTHER PROCEEDING; AND EXPRESSLY INCLUDING ANY SUCH LOSSES, LIABILITIES, CLAIMS, DAMAGES, OR EXPENSE INCURRED BY REASON OF THE PERSON BEING INDEMNIFIED’S OWN NEGLIGENCE, BUT EXCLUDING ANY SUCH LOSSES, LIABILITIES, CLAIMS, DAMAGES OR EXPENSES WHICH ARE FOUND BY A FINAL, NON-APPEALABLE JUDGMENT BY A COURT OF COMPETENT JURISDICTION TO HAVE RESULTED FROM THE GROSS NEGLIGENCE, BAD FAITH OR WILLFUL MISCONDUCT OF THE PERSON TO BE INDEMNIFIED OR ARISING OUT OF DISPUTES AMONG THE LENDERS (OTHER THAN DISPUTES INVOLVING THE ARRANGERS IN THEIR CAPACITIES AS JOINT LEAD ARRANGERS OR DISPUTES INVOLVING WELLS

FARGO IN ITS CAPACITY AS ADMINISTRATIVE AGENT). THE COVENANTS AND INDEMNITIES PROVIDED IN THIS SECTION SHALL SURVIVE THE REPAYMENT OR ANY OTHER SATISFACTION OF THE OBLIGATIONS OF THE BORROWER UNDER THE CREDIT DOCUMENTS.

     Section 9.08. Execution in Counterparts. This Agreement may be executed in any number of counterparts and by different parties hereto in separate counterparts, each of which when so executed shall be deemed to be an original and all of which taken together shall constitute one and the same agreement. Delivery of an executed counterpart of a signature page of this Agreement by facsimile or other electronic transmission (including via e-mail) shall be effective as delivery of a manually executed counterpart to this Agreement.

     Section 9.09. Survival of Representations, etc. All representations and warranties contained in this Agreement or made in writing by or on behalf of the Borrower in connection herewith shall survive the execution and delivery of this Agreement and the Credit Documents, the making of the Advances and any investigation made by or on behalf of the Administrative Agent or any Lender, none of which investigations shall diminish the Administrative Agent’s or any Lender’s right to rely on such representations and warranties. All obligations of the Borrower provided for in Sections 2.10, 2.11, 2.12, 9.04 and 9.07 and all of the obligations of the Lenders in Section 2.09 and 8.08 shall survive any termination of this Agreement and repayment in full of the Obligations.

     Section 9.10. Severability. In case one or more provisions of this Agreement or the other Credit Documents shall be invalid, illegal, or unenforceable in any respect under any applicable law, the validity, legality, and enforceability of the remaining provisions contained herein or therein shall not be affected or impaired thereby. Without limiting the foregoing provisions of this Section 9.10, if and to the extent that the enforceability of any provisions in this Agreement relating to Defaulting Lenders shall be limited by applicable bankruptcy laws, as determined in good faith by the Administrative Agent or the Issuing Banks, as applicable, then such provisions shall be deemed to be in effect only to the extent not so limited.

     Section 9.11. Business Loans. The Borrower warrants and represents that the Advances evidenced by the Notes are and shall be for business, commercial, investment, or other similar purposes and not primarily for personal, family, household, or agricultural use, as such terms are used in Chapter One (“Chapter One”) of the Texas Credit Code. At all such times, if any, as Chapter One shall establish a Maximum Rate, the Maximum Rate shall be the “indicated rate ceiling” (as such term is defined in Chapter One) from time-to-time in effect.

     Section 9.12. Usury Not Intended. It is the intent of the Borrower, the Administrative Agent, the Issuing Banks, and the Lenders in the execution and performance of this Agreement and the other Credit Documents to contract in strict compliance with applicable usury laws, including conflicts of law concepts, governing the Advances of the Lenders including such applicable laws of the State of Texas and the United States of America from time-to-time in effect. In furtherance thereof, the Administrative Agent, the Lenders, and the Borrower stipulate and agree that none of the terms and provisions contained in this Agreement or the other Credit Documents shall ever be construed to create a contract to pay, as consideration for the use, forbearance or detention of money, interest at a rate in excess of the Maximum Rate and that for purposes hereof “interest” shall include the aggregate of all charges which constitute interest under such laws that are contracted for, charged, or received under this Agreement and the other Credit Documents; and in the event that, notwithstanding the foregoing, under any circumstances the aggregate amounts taken, reserved, charged, received, or paid on the Advances, include amounts which by applicable law are deemed interest which would exceed the Maximum Rate, then such excess shall be deemed to be a mistake and the Lender receiving same shall credit the same on the principal of its Notes

L.P. Credit Agreement

(or if its Notes shall have been paid in full, refund said excess to the Borrower). In the event that the maturity of the Notes is accelerated by reason of any election of the holder thereof resulting from any Event of Default under this Agreement or otherwise, or in the event of any required or permitted prepayment, then such consideration that constitutes interest may never include more than the Maximum Rate and excess interest, if any, provided for in this Agreement or otherwise shall be canceled automatically as of the date of such acceleration or prepayment and, if theretofore paid, shall be credited on the Notes (or, if the Notes shall have been paid in full, refunded to the Borrower of such interest). The provisions of this Section shall control over all other provisions of this Agreement or the other Credit Documents which may be in apparent conflict herewith. In determining whether or not the interest paid or payable under any specific contingencies exceeds the Maximum Rate, the Borrower, the Administrative Agent, the Issuing Banks, and the Lenders shall to the maximum extent permitted under applicable law amortize, prorate, allocate and spread in equal parts during the period of the full stated term of the Note, all amounts considered to be interest under applicable law at any time contracted for, charged, received or reserved in connection with the Obligations.

     Section 9.13. Waiver of Jury; Waiver of Consequential Damages; Consent to Jurisdiction.

     (a) The Borrower, the Administrative Agent, the Issuing Banks, and each Lender hereby irrevocably waive any and all right to trial by jury in respect of any legal proceeding arising out of or relating to this Agreement, or any other Credit Document, or any of the transactions contemplated hereby.

     (b) Waiver of Consequential Damages, Etc. To the fullest extent permitted by applicable law, the Borrower, the Administrative Agent, the Issuing Banks and each Lender hereby agree that they shall not assert, and hereby waive, any claim against any such Person which they may have against any other such Person and such Person’s respective Affiliates, directors, officers, employees and agents, on any theory of liability, for special, indirect, consequential or punitive damages (as opposed to direct or actual damages) arising out of, in connection with, or as a result of, this Agreement, any other Credit Document or any agreement or instrument contemplated hereby, the transactions contemplated hereby or thereby, any Advance or Letter of Credit Obligation or the use of the proceeds thereof; provided that the foregoing shall not apply to any consequential damages payable to a third person (that is, a Person other than the Borrower, the Administrative Agent, the Issuing Banks, any Lender and each of the foregoing’s respective Affiliates, directors, officers, employees and agents) for which indemnification is sought under this Agreement.

     (c) The Borrower hereby irrevocably submits to the jurisdiction of any Texas state or federal court sitting in Dallas, Texas in any action or proceeding arising out of or relating to this Agreement or the other Credit Documents, and the transactions contemplated thereby and the Borrower hereby irrevocably agrees that all claims in respect of such action or proceeding may be heard and determined in such court. The Borrower hereby unconditionally and irrevocably waives, to the fullest extent it may effectively do so, any right it may have to the defense of an inconvenient forum to the maintenance of such action or proceeding. The Borrower hereby agrees that service of copies of the summons and complaint and any other process which may be served in any such action or proceeding may be made by mailing or delivering a copy of such process to such Borrower at its address set forth in this Agreement. The Borrower agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law. Nothing in this Section shall affect the rights of any Lender to serve legal process in any other manner permitted by the law or affect the right of any Lender to bring any action or proceeding against the Borrower or its Property in the courts of any other jurisdiction.

(“Borrower”), certain lenders party thereto from time to time (the “Original Lenders”), and Union Bank, N.A., formerly known as Union Bank of California, N.A., as the administrative agent (the “Predecessor Administrative Agent”).

     B. The Original Credit Agreement was amended and restated in its entirety by that certain Amended and Restated Credit Agreement dated as of August 27, 2007 entered into by the Borrower, the Predecessor Administrative Agent, Bank of America, N.A., as syndication agent, Guaranty Bank, as predecessor in interest to BBVA Compass Bank, as documentation agent, and the lenders party thereto, including certain of the Lenders (as heretofore amended, the “Prior Credit Agreement”).

     C. In order to secure the full and punctual payment and performance of the obligations under the Prior Credit Agreement and other Credit Documents (as defined in the Prior Credit Agreement), some of the Guarantors (as defined in the Prior Credit Agreement) amended and restated the Original Guaranty and executed and delivered that certain Amended and Restated Guaranty Agreement dated August 27, 2007 (the “Existing Guaranty”).

     D. The Borrower has requested certain amendments to the Prior Credit Agreement which include, among other things, the replacement of Union Bank, N.A. as administrative agent and issuing bank by Wells Fargo Bank, N.A.

     E. The Prior Credit Agreement is being amended and restated in its entirety pursuant to that certain Second Amended and Restated Credit Agreement dated as of February __, 2011 (as amended, restated, supplemented and otherwise modified from time to time, the “Credit Agreement”) among the Borrower, the Lenders, the Predecessor Administrative Agent and the Administrative Agent.

     F. The Guarantors are Subsidiaries or Affiliates of the Borrower and will derive substantial direct and indirect benefit from (i) the transactions contemplated by the Credit Agreement, and the other Credit Documents (as defined in the Credit Agreement), and (ii) the Lender Hedging Agreements (as defined in the Credit Agreement) entered into by the Borrower or any of its Subsidiaries with a Lender or an Affiliate of a Lender (each such counterparty being referred to as a “Swap Counterparty”).

     G. It is a requirement under the Credit Agreement that the Grantors shall continue to guarantee the due payment and performance of all Obligations (as defined in the Credit Agreement) by amending and restating in its entirety the Existing Guaranty as set forth herein.

     NOW, THEREFORE, in consideration of the premises, each Guarantor hereby agrees (a) that the Existing Guaranty is amended and restated in its entirety as follows and (b) further agrees as follows:

Without limiting the generality of the foregoing, each Guarantor’s liability shall extend to all amounts that constitute part of the Guaranteed Obligations and would be owed by the Borrower or any of its Subsidiaries to the Administrative Agent, any Issuing Bank or any Lender under the Credit Documents and by the Borrower or any of its Subsidiaries to any Swap Counterparty but for the fact that they are unenforceable or not allowable due to insolvency or the existence of a bankruptcy, reorganization or similar proceeding involving the Borrower.

Accordingly, notwithstanding anything to the contrary contained in this Guaranty or in any other agreement or instrument executed in connection with the payment of any of the Guaranteed Obligations, the amount of the Guaranteed Obligations guaranteed by a Guarantor under this Guaranty shall be limited to an aggregate amount equal to the largest amount that would not render such Guarantor’s obligations hereunder subject to avoidance under Section 548 of the United States Bankruptcy Code or any comparable provision of any other applicable law.

     Section 3. Guaranty Absolute.

The obligations of each Guarantor under this Guaranty are independent of the Guaranteed Obligations or any other obligations of any other Person under the Credit Documents or in connection with any Lender Hedging Agreement or Banking Service Obligations, and a separate action or actions may be brought and prosecuted against any Guarantor to enforce this Guaranty, irrespective of whether any action is brought against the Borrower, any other Guarantor or any other Person or whether the Borrower, any other Guarantor or any other Person is joined in any such action or actions.

     (c) any taking, exchange, release or non-perfection of any Collateral, or any taking, release or amendment or waiver of or consent to departure from any other guaranty, for all or any of the Guaranteed Obligations;

     (d) any manner of application of Collateral, or proceeds thereof, to all or any of the Guaranteed Obligations, or any manner of sale or other disposition of any Collateral for all or any of the Guaranteed Obligations or any other obligations of any other Person under the Credit Documents or any other assets of the Borrower or any of its Subsidiaries;

     (e) any change, restructuring or termination of the corporate structure or existence of the Borrower or any of its Subsidiaries or any Guarantor;

     (f) any failure of any Lender, the Administrative Agent, any Issuing Bank or any other Beneficiary to disclose to the Borrower or any Guarantor any information relating to the business, condition (financial or otherwise), operations, properties or prospects of any Person now or in the future known to the Administrative Agent, any Issuing Bank, any Lender or any other Beneficiary (and each Guarantor hereby irrevocably waives any duty on the part of any Beneficiary to disclose such information);

     (g) any signature of any officer of the Borrower or any Guarantor being mechanically reproduced in facsimile or otherwise; or

     (h) any other circumstance or any existence of or reliance on any representation by any Beneficiary that might otherwise constitute a defense available to, or a discharge of, the Borrower, any Guarantor or any other guarantor, surety or other Person.

     Section 4. Continuation and Reinstatement, Etc. Each Guarantor agrees that, to the extent that payments of any of the Guaranteed Obligations are made, or any Beneficiary receives any proceeds of Collateral, and such payments or proceeds or any part thereof are subsequently invalidated, declared to be fraudulent or preferential, set aside, or otherwise required to be repaid, then to the extent of such repayment the Guaranteed Obligations shall be reinstated and continued in full force and effect as of the date such initial payment or collection of proceeds occurred. EACH GUARANTOR SHALL DEFEND AND INDEMNIFY EACH BENEFICIARY FROM AND AGAINST ANY CLAIM, DAMAGE, LOSS, LIABILITY, COST OR EXPENSE UNDER THIS SECTION 4 (INCLUDING REASONABLE ATTORNEYS’ FEES AND EXPENSES) IN THE DEFENSE OF ANY SUCH ACTION OR SUIT INCLUDING SUCH CLAIM, DAMAGE, LOSS, LIABILITY, COST, OR EXPENSE ARISING AS A RESULT OF THE INDEMNIFIED BENEFICIARY’S OWN NEGLIGENCE BUT EXCLUDING SUCH CLAIM, DAMAGE, LOSS, LIABILITY, COST, OR EXPENSE THAT IS FOUND IN A FINAL, NON-APPEALABLE JUDGMENT BY A COURT OF COMPETENT JURISDICTION TO HAVE RESULTED FROM SUCH INDEMNIFIED BENEFICIARY’S GROSS NEGLIGENCE, BAD FAITH OR WILLFUL MISCONDUCT OR ARISING OUT OF DISPUTES AMONG THE BENEFICIARIES (OTHER THAN DISPUTES INVOLVING THE ARRANGERS IN THEIR CAPACITIES AS JOINT LEAD ARRANGERS OR

DISPUTES INVOLVING WELLS FARGO IN ITS CAPACITY AS ADMINISTRATIVE AGENT).

     Section 5. Waivers and Acknowledgments.

     (a) Each Guarantor hereby waives promptness, diligence, presentment, notice of acceptance and any other notice with respect to any of the Guaranteed Obligations and this Guaranty and any requirement that any Beneficiary protect, secure, perfect or insure any Lien or any property or exhaust any right or take any action against the Borrower or any other Person or any Collateral.

     (b) Each Guarantor hereby irrevocably waives any right to revoke this Guaranty, and acknowledges that this Guaranty is continuing in nature and applies to all Guaranteed Obligations, whether existing now or in the future.

     (c) Each Guarantor acknowledges that it will receive substantial direct and indirect benefits from the financing arrangements involving the Borrower contemplated by the Credit Documents and the Lender Hedging Agreements with the Swap Counterparties and that the waivers set forth in this Guaranty are knowingly made in contemplation of such benefits.

     Section 6. Subrogation. No Guarantor will exercise any rights that it may now have or hereafter acquire against the Borrower or any other Person to the extent that such rights arise from the existence, payment, performance or enforcement of such Guarantor’s obligations under this Guaranty or any other Credit Document, including, without limitation, any right of subrogation, reimbursement, exoneration, contribution or indemnification and any right to participate in any claim or remedy of any Beneficiary against the Borrower or any other Person, whether or not such claim, remedy or right arises in equity or under contract, statute or common law, including, without limitation, the right to take or receive from the Borrower or any other Person, directly or indirectly, in cash or other property or by set-off or in any other manner, payment or security on account of such claim, remedy or right, unless and until all of the Guaranteed Obligations and any and all other amounts payable by the Guarantors under this Guaranty shall have been paid in full in cash, all Letters of Credit have terminated or expired and no Letter of Credit Obligations shall remain outstanding, all Lender Hedging Agreements with the Beneficiaries have been terminated, and all Commitments shall have expired or terminated.

     A. Reference is made to the Second Amended and Restated Credit Agreement dated as of February __, 2011 (as amended, supplemented or otherwise modified from time to time, the “Credit Agreement”), among the Borrower, the Lenders from time to time party thereto (the “Lenders”), and the Administrative Agent.

     B. Capitalized terms used herein and not otherwise defined herein shall have the meanings assigned to such terms in the Guaranty Agreement or the Credit Agreement.

     C. The Guarantors have entered into the Guaranty Agreement in order to induce the Lenders to make Advances and the Issuing Banks to issue Letters of Credit. Pursuant to Section 5.10 of the Credit Agreement, certain Material Subsidiaries of the Borrower are required to enter into the Guaranty Agreement as Guarantors. Section 18 of the Guaranty Agreement provides that additional Material Subsidiaries of the Borrower may become Guarantors under the Guaranty Agreement by execution and delivery of an instrument in the form of this Supplement. The undersigned Material Subsidiary of the Borrower (the “New Guarantor”) is executing this Supplement in accordance with the requirements of the Credit Agreement to become a Guarantor under the Guaranty Agreement in order to induce the Lenders to make additional Advances and the Issuing Banks to issue additional Letters of Credit and as consideration for Advances previously made and Letters of Credit previously issued.

     Accordingly, the Administrative Agent and the New Guarantor agree as follows:

     1. In accordance with Section 18 of the Guaranty Agreement, the New Guarantor by its signature below becomes a Guarantor under the Guaranty Agreement with the same force and effect as if originally named therein as a Guarantor and the New Guarantor hereby (a) agrees to all the terms and provisions of the Guaranty Agreement applicable to it as a Guarantor thereunder and (b) represents and warrants that the representations and warranties made by it as a Guarantor thereunder are true and correct in all material respects on and as of the date hereof. Each reference to a “Guarantor” in the Guaranty Agreement shall be deemed to include the New Guarantor. The Guaranty Agreement is hereby incorporated herein by reference.

     2. The New Guarantor represents and warrants to the Administrative Agent and the other Beneficiaries that this Supplement has been duly authorized, executed and delivered by it and constitutes its legal, valid and binding obligation, enforceable against it in accordance with its terms (subject to applicable bankruptcy, reorganization, insolvency, moratorium or similar laws affecting creditors’ rights generally and subject, as to enforceability, to equitable principles of general application (regardless of whether enforcement is sought in a proceeding in equity or at law)).

     3. This Supplement may be executed in counterparts, each of which shall constitute an original, but all of which when taken together shall constitute a single contract. This Supplement shall become effective when the Administrative Agent shall have received counterparts of this Supplement that, when taken together, bear the signatures of the New Guarantor and the Administrative Agent.

The New Guarantor hereby irrevocably waives, to the fullest extent it may effectively do so, any right it may have to the defense of an inconvenient forum to the maintenance of such action or proceeding. The New Guarantor hereby agrees that service of copies of the summons and complaint and any other process which may be served in any such action or proceeding may be made by mailing or delivering a copy of such process to such Guarantor at its address set forth on the signature page hereof. The New Guarantor agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law. Nothing in this Section shall affect the rights of any Beneficiary to serve legal process in any other manner permitted by law or affect the right of any Beneficiary to bring any action or proceeding against the New Guarantor or its Property in the courts of any other jurisdiction.

     6. In case any one or more of the provisions contained in this Supplement should be held invalid, illegal or unenforceable in any respect, the validity, legality and enforceability of the remaining provisions contained herein and in the Guaranty Agreement shall not in any way be affected or impaired thereby (it being understood that the invalidity of a particular provision hereof in a particular jurisdiction shall not in and of itself affect the validity of such provision in any other jurisdiction). The parties hereto shall endeavor in good-faith negotiations to replace the invalid, illegal or unenforceable provisions with valid provisions the economic effect of which comes as close as possible to that of the invalid, illegal or unenforceable provisions.

     7. All communications and notices hereunder shall be in writing and given as provided in Section 10 of the Guaranty Agreement. All communications and notices hereunder to the New Guarantor shall be given to it at the address set forth under its signature below.

GRANTING CLAUSES; SECURED OBLIGATIONS

     2.1 Conveyance and Grant of Lien. In consideration of the advances, issuances, or extensions by the Credit Parties to Borrower of the funds or credit constituting the Secured Obligations (including the making of the Advances and the issuing of the Letters of Credit), and in further consideration of the mutual covenants contained herein, Mortgagor, by this Deed of Trust hereby GRANTS, SELLS, TRANSFERS, ASSIGNS AND CONVEYS with a general warranty of title, and WITH THE POWER OF SALE, for the uses, purposes and conditions hereinafter set forth, all of its right, title and interest in and to the Mortgaged Property unto Trustee, and to his successor or successors or substitutes IN TRUST, WITH POWER OF SALE, to secure the payment and performance of the Secured Obligations for the benefit of Mortgagee and the ratable benefit of the Credit Parties.

     TO HAVE AND TO HOLD the Mortgaged Property unto the Trustee and his successors or substitutes in trust and to his and their successors and assigns forever for the benefit of the Credit Parties, together with all and singular the rights, hereditaments and appurtenances thereto in anywise appertaining or belonging, to secure payment of the Secured Obligations and the performance of the covenants of Mortgagor contained in this Deed of Trust. Mortgagor does hereby bind itself, its successors and permitted assigns, to warrant and forever defend all and singular the Mortgaged Property unto the Trustee and his successors or substitutes in trust, and their successors and assigns, against every person whomsoever lawfully claiming or to claim the same, or any part thereof.

     Notwithstanding anything to the contrary in the foregoing, to the extent applicable to any Lease, Servitude, or other portion of the Mortgaged Property, the conveyance and grant of Liens and security interests under this Mortgage are subject to the Third Party Consent Limitation and shall not be deemed to have been made with respect to the applicable portion(s) of the Mortgaged Property (but no other portion of the Mortgaged Property) until the receipt, if at all, of the applicable third-party consent.

     2.2 Conveyance and Grant of Security Interest. For the same consideration and to further secure the Secured Obligations, Mortgagor hereby grants to Mortgagee for its benefit and the ratable benefit of the other Credit Parties a security interest in and to the Mortgaged Property.

     2.3 Assignment of Rents and Leases. Mortgagor hereby assigns, transfers, conveys, and sets over to Mortgagee all of Mortgagor’s estate, right, title and interest in, to and under the Leases, whether existing on the date hereof or hereafter entered into, together with any changes, extensions, revisions or modifications thereof and all rights, powers, privileges, options and other benefits of Mortgagor as the lessor under the Leases regarding the current tenants and any future tenants, and all the Rents from the Leases, including those now due, past due, or to become due. Mortgagor irrevocably appoints Mortgagee its true and lawful attorney-in-fact, at the option of Mortgagee, upon the occurrence and during the continuance of an Event of Default, to take possession and control of the applicable portions of the Mortgaged Property, pursuant to Mortgagor’s rights under the Leases, to exercise any of Mortgagor’s rights under the Leases, and to demand, receive and enforce payment, to give receipts, releases and satisfaction and to sue, in the name of Mortgagor or Mortgagee, for all of the Rents. The power of attorney granted hereby shall be irrevocable and coupled with an interest and shall terminate only upon the indefeasible payment in full in cash of the Secured Obligations (including all Letter of Credit Obligations), the termination or expiration of all Letters of Credit and all obligations of the Issuing Banks and the Lenders in respect of Letters of Credit, and the expiration or termination of all Commitments, and Mortgagor hereby releases Mortgagee from all liability (other than as a result of the gross negligence or willful misconduct of Mortgagee) whatsoever for the exercise of the foregoing power of attorney and all actions taken pursuant thereto. The consideration received by Mortgagor to execute and deliver this assignment and the Liens and security interests created herein is legally sufficient and will provide a direct economic benefit to Mortgagor. It is intended by Mortgagor and Mortgagee that the assignment set forth herein constitutes an absolute assignment and not merely an assignment for additional security. Notwithstanding the foregoing, this assignment shall not be construed to bind Mortgagee to the performance of any of the covenants, conditions, or provisions of Mortgagor contained in the Leases or otherwise to impose any obligation upon Mortgagee, and, so long as no Event of Default shall have occurred and be continuing, Mortgagor shall have a license, revocable by Mortgagee, to possess and control the Leases and collect and receive the Rents. Upon the occurrence of an Event of Default, such license in favor of Mortgagor shall be automatically revoked. Mortgagee’s acceptance of the assignment of the Rents under this Deed of Trust shall not be deemed to constitute Mortgagee a “secured party in possession,” nor obligate Mortgagee to appear in or defend any proceeding relating to the Rents, any Leases, or the Mortgaged Property, or to take any action hereunder, expend any money, incur any expenses, or perform any obligation under any Leases.

     2.4 After-Acquired Mortgaged Property. Any and all of the Mortgaged Property which is acquired after the date of this Deed of Trust shall, immediately and without any further conveyance, assignment, or act on the part of Mortgagor or Mortgagee, be subject to the Liens granted pursuant to this Deed of Trust as fully and completely as though specifically described herein and as though such Mortgaged Property had been owned by Mortgagor on the date of this Deed of Trust.

     2.5 Revolving Credit and Future Advances. It is contemplated and acknowledged that the Secured Obligations may include revolving credit loans and advances from time to time, and that this Deed of Trust shall have effect as of the date hereof to secure all Secured Obligations, regardless of whether any amounts are advanced on the date hereof or on a later date or, whether having been advanced, are later repaid in part or in whole and further advances made at a later date. This Deed of Trust secures all future advances and obligations constituting Secured Obligations.

     2.6 Security for Secured Obligations. The Liens and other rights granted pursuant to Section 2.1 and Section 2.2 of this Deed of Trust secure, and the Mortgaged Property is security for, the prompt performance and payment in full in cash when due, whether at stated maturity, by acceleration or otherwise, of the Secured Obligations. Notwithstanding that the balance of the Secured Obligations may at certain times be zero and that no Secured Obligations may at certain times be outstanding, the Liens granted hereunder and this Deed of Trust shall remain in full force and effect at all times and with the same priority until the payment in full in cash of the Secured Obligations and the expiration or termination of the Credit Documents.

     2.7 Products and Proceeds. The Liens and security interests granted by Mortgagor under this Deed of Trust include all products and Proceeds of the Mortgaged Property.

Mortgagor shall take such action, employing attorneys agreeable to Mortgagee, as may be necessary to preserve Mortgagor’s, the Trustee’s and Mortgagee’s rights affected thereby. If Mortgagor fails or refuses to adequately or vigorously, in the reasonable judgment of Mortgagee, defend Mortgagor’s, the Trustee’s or Mortgagee’s rights to the Mortgaged Property, the Trustee or Mortgagee may take such action on behalf of and in the name of Mortgagor and at Mortgagor’s expense. Moreover, Mortgagee or the Trustee on behalf of Mortgagee, may take such independent action in connection therewith as they may in their discretion deem proper, including the right to employ independent counsel and to intervene in any suit affecting the Mortgaged Property. All costs, expenses and attorneys’ fees incurred by Mortgagee or the Trustee pursuant to this Section 3.3 or in connection with the defense by Mortgagee of any claims, demands or litigation relating to Mortgagor, the Mortgaged Property or the transactions contemplated in this Deed of Trust shall be paid by Mortgagor as provided in Section 6.2 below.

     3.5 Records, Statements and Reports. Mortgagor shall keep proper books of record and account in which complete and correct entries shall be made of Mortgagor’s transactions in accordance with the method of accounting required in the Credit Agreement and shall furnish or cause to be furnished to Mortgagee the reports required to be delivered pursuant to the terms of the Credit Agreement.

     3.6 Covenants Running with the Land. All covenants and agreements herein contained shall constitute covenants running with the Land.

If any Event of Default pursuant to paragraph (e) of Section 7.01 of the Credit Agreement shall occur, the entire unpaid principal of, and the interest accrued on, and all other amounts owed in connection with, the Secured Obligations shall immediately and automatically become and be due and payable in full, without presentment, demand, protest or any notice of any kind (including, without limitation, any notice of intent to accelerate or notice of acceleration) all of which are hereby expressly waived by Mortgagor. Whether or not Mortgagee or the Majority Lenders elect to accelerate as herein provided, Mortgagee may simultaneously, or thereafter, without any further notice to Mortgagor, exercise any other right or remedy provided in this Deed of Trust or otherwise existing under the Credit Agreement or any other Credit Document or any other agreement, document, or instrument evidencing obligations owing from Mortgagor to any of the Credit Parties.

ARTICLE V

Mortgagee’s Rights

     5.1 Rights to Realty Collateral Upon Default.

     (a) Operation of Property by Mortgagee. Upon the occurrence and during the continuance of any Event of Default, and in addition to all other rights of Mortgagee, Mortgagee shall have the following rights and powers (but no obligation):

     (i) To hold, use, administer, manage and operate the Realty Collateral to the extent that Mortgagor could do so, and without any liability to Mortgagor in connection with such operations; and

     (ii) Either in person or by agent, with or without bringing any action or proceeding, or by a receiver appointed by a court, and without regard to the adequacy of its security, to enter upon and take possession of the Realty Collateral or any part thereof, and exclude Mortgagor therefrom, and do any other acts which it deems necessary or desirable to preserve the value, marketability or rentability of the Realty Collateral, or part thereof or interest therein, increase the income therefrom or protect the security hereof and, with or without taking possession of the Realty Collateral, take any action described herein, sue for or otherwise collect the Rents, including those past due and unpaid, and apply the same, less reasonable costs and expenses of operation and

collection including reasonable attorneys’ fees, upon the Secured Obligations, all in such order as Mortgagee may determine.

The entering upon and taking possession of the Realty Collateral, the taking of any action described herein, the collection of such Rents, and the application thereof as aforesaid, shall not cure or waive any Event of Default or notice of default or invalidate any act done in response to such Event of Default or pursuant to such notice of default and, notwithstanding the continuance in possession of the Realty Collateral or the collection, receipt and application of Rents, Mortgagee shall be entitled to exercise every right provided for in any of the Credit Documents or by law upon any Event of Default, including the right to exercise the power of sale herein conferred. Mortgagee may designate any person, firm, corporation or other entity to act on its behalf in exercising the foregoing rights and powers.

     (b) Judicial Proceedings. Upon the occurrence and during the continuance of any Event of Default, the Trustee and/or Mortgagee, in lieu of or in addition to exercising the power of sale hereafter given, may proceed by a suit or suits, in equity or at law (i) for the specific performance of any covenant or agreement herein contained or in aid of the execution of any power herein granted, (ii) for the appointment of a receiver whether there is then pending any foreclosure hereunder or the sale of the Realty Collateral, or (iii) for the enforcement of any other appropriate legal or equitable remedy; and further, in lieu of the non-judicial power of sale hereafter given for Mortgaged Property located in the State of Texas, the Trustee may proceed by suit for a sale of the Realty Collateral.

     (c) Foreclosure by Private Power of Sale of Collateral. Upon the occurrence and during the continuance of any Event of Default, the Trustee shall have the right and power to sell, as the Trustee may elect, all or a portion of the Mortgaged Property at one or more sales as an entirety or in parcels, in accordance with Section 51.002 of the Texas Property Code, as amended from time to time (or any successor provisions of Texas law governing real property foreclosure sales) or with any applicable state law. Mortgagor hereby designates as Mortgagor’s address for the purpose of notice the address set out in Section 6.12; provided that Mortgagor may by written notice to Mortgagee designate a different address for notice purposes. Any purchaser or purchasers will be provided with a general warranty conveyance binding Mortgagor and Mortgagor’s successors and assigns. Sale of a part of the Realty Collateral will not exhaust the power of sale, and sales may be made from time to time until all of the Realty Collateral is sold or all of the Secured Obligations are paid in full.

     (d) Certain Aspects of Sale. Mortgagee will have the right to become the purchaser at any foreclosure sale and to credit the then outstanding balance of the Secured Obligations against the amount payable by Mortgagee as purchaser at such sale. Statements of fact or other recitals contained in any conveyance to any purchaser or purchasers at any sale made hereunder will conclusively establish the occurrence of any Event of Default, any acceleration of the maturity of the Secured Obligations, the advertisement and conduct of such sale in the manner provided herein, the appointment of any successor-Trustee hereunder and the truth and accuracy of all other matters stated therein. Mortgagor does hereby ratify and confirm all legal acts that the Trustee may do in carrying out the Trustee’s duties and obligations under this Deed of Trust, and Mortgagor hereby irrevocably appoints Mortgagee to be the attorney-in-fact of Mortgagor and in the name and on behalf of Mortgagor to execute and deliver any deeds, transfers, conveyances, assignments, assurances and notices which Mortgagor ought to execute and deliver and do and perform any and all such acts and things which Mortgagor ought to do and perform under the covenants herein contained and generally to use the name of Mortgagor in the exercise of all or any of the powers hereby conferred on Trustee. Upon any sale, whether under the power of sale

hereby given or by virtue of judicial proceedings, it shall not be necessary for Trustee or any public officer acting under execution or by order of court, to have physically present or constructively in his possession any of the Mortgaged Property, and Mortgagor hereby agrees to deliver to the purchaser or purchasers at such sale on the date of sale the Mortgaged Property purchased by such purchasers at such sale and if it should be impossible or impracticable to make actual delivery of such Mortgaged Property, then the title and right of possession to such Mortgaged Property shall pass to the purchaser or purchasers at such sale as completely as if the same had been actually present and delivered.

     (e) Receipt to Purchaser. Upon any sale made under the power of sale herein granted, the receipt of the Trustee will be sufficient discharge to the purchaser or purchasers at any sale for its purchase money, and such purchaser or purchasers, will not, after paying such purchase money and receiving such receipt of the Trustee, be obligated to see to the application of such purchase money or be responsible for any loss, misapplication or non-application thereof.

     (f) Effect of Sale. Any sale or sales of the Realty Collateral will operate to divest all right, title, interest, claim and demand whatsoever, either at law or in equity, of Mortgagor in and to the premises and the Realty Collateral sold, and will be a perpetual bar, both at law and in equity, against Mortgagor, Mortgagor’s successors or assigns, and against any and all persons claiming or who shall thereafter claim all or any of the Realty Collateral sold by, through or under Mortgagor, or Mortgagor’s successors or assigns. Nevertheless, if requested by the Trustee so to do, Mortgagor shall join in the execution and delivery of all proper conveyances, assignments and transfers of the Property so sold. The purchaser or purchasers at the foreclosure sale will receive as incident to his, her, its or their own ownership, immediate possession of the Realty Collateral purchased and Mortgagor agrees that if Mortgagor retains possession of the Realty Collateral or any part thereof subsequent to such sale, Mortgagor will be considered a tenant at sufferance of the purchaser or purchasers and will be subject to eviction and removal by any lawful means, with or without judicial intervention, and all damages by reason thereof are hereby expressly waived by Mortgagor.

     (g) Application of Proceeds. The proceeds of any sale of the Realty Collateral or any part thereof, whether under the power of sale herein granted and conferred or by virtue of judicial proceedings, shall either be, at the option of Mortgagee, applied at the time of receipt, or held by Mortgagee in a cash collateral account as additional Mortgaged Property, and in either case, applied in the order set forth in Section 7.06 of the Credit Agreement.

     (h) Mortgagor’s Waiver of Appraisement and Marshalling. Mortgagor agrees, to the full extent that Mortgagor may lawfully so agree, that Mortgagor will not at any time insist upon or plead or in any manner whatever claim the benefit of any appraisement, valuation, stay, extension or redemption law, now or hereafter in force, in order to prevent or hinder the enforcement or foreclosure of this Deed of Trust, the absolute sale of the Mortgaged Property, including the Realty Collateral, or the possession thereof by any purchaser at any sale made pursuant to this Deed of Trust or pursuant to the decree of any court of competent jurisdiction; and Mortgagor, for Mortgagor and all who may claim through or under Mortgagor, hereby waives the benefit of all such laws and, to the extent that Mortgagor may lawfully do so under any applicable law, any and all rights to have the Mortgaged Property, including the Realty Collateral, marshaled upon any foreclosure of the Lien hereof or sold in inverse order of alienation. Mortgagor agrees that the Trustee may sell the Mortgaged Property, including the Realty Collateral, in part, in parcels or as an entirety as directed by Mortgagee.

     (i) Waiver of Notices, Appraisements, Reinstatement and other Rights. Mortgagor hereby expressly waives, to the full extent permitted by applicable law, any and all rights or privileges of notices, appraisements, redemption and any prerequisite in the event of foreclosure of the Liens and/or security interests created herein, including without limitation, any right to reinstatement prior to foreclosure. Mortgagee at all times shall have the right to release any part of the Mortgaged Property now or hereafter subject to the Liens or security interests of this Deed of Trust, any part of the proceeds of production or other income herein or hereafter assigned or pledged, or any other security it now has or may hereafter have securing the Indebtedness, without releasing any other part of the Mortgaged Property, proceeds or income, and without affecting the Liens or security interests hereof as to the part or parts of the Mortgaged Property, proceeds or income not so released or the right to receive future proceeds and income

     5.2 Rights to Personalty Collateral Upon Default. Upon the occurrence and during the continuance of any Event of Default, Mortgagee or the Trustee may proceed against the Personalty Collateral in accordance with the rights and remedies granted herein with respect to the Realty Collateral, or will have all rights and remedies granted by the Uniform Commercial Code as in effect in Texas and this Deed of Trust. Mortgagee shall have the right to take possession of the Personalty Collateral, and for this purpose Mortgagee may enter upon any premises on which any or all of the Personalty Collateral is situated and, to the extent that Mortgagor could do so, take possession of and operate the Personalty Collateral or remove it therefrom. Mortgagee may require Mortgagor to assemble the Personalty Collateral and make it available to Mortgagee at a place to be designated by Mortgagee which is reasonably convenient to both parties. Unless the Personalty Collateral is perishable or threatens to decline speedily in value or is of a type customarily sold on a recognized market, Mortgagee will send Mortgagor reasonable notice of the time and place of any public sale or of the time after which any private sale or other disposition of the Personalty Collateral is to be made. This requirement of sending reasonable notice will be met if such notice is mailed, postage prepaid, to Mortgagor at the address designated in Section 6.12 hereof (or such other address as has been designated as provided herein) at least ten days before the time of the sale or disposition. In addition to the expenses of retaking, holding, preparing for sale, selling and the like, Mortgagee will be entitled to recover attorney’s fees and legal expenses as provided for in this Deed of Trust and in the writings evidencing the Secured Obligations before applying the balance of the proceeds from the sale or other disposition toward satisfaction of the Secured Obligations. Mortgagor will remain liable for any deficiency remaining after the sale or other disposition. Mortgagor hereby consents and agrees that any disposition of all or a part of the Mortgaged Property may be made without warranty of any kind whether expressed or implied.

     5.3 Rights to Fixture Collateral Upon Default. Upon the occurrence and during the continuance of any Event of Default, Mortgagee may elect to treat the Fixture Collateral as either Realty Collateral or as Personalty Collateral (but not both) and proceed to exercise such rights as apply to the type of Mortgaged Property selected.

     5.4 Certain Remedies related to Rents. After the occurrence and during the continuance of an Event of Default, the Mortgagee may by written notice to Mortgagor terminate Mortgagor’s license to collect the Rents hereunder. Any Rents received by Mortgagor after such notice shall be held in trust for the benefit of the Mortgagee, segregated from the other funds of Mortgagor, and immediately paid over to the Mortgagee, with any necessary endorsement. Mortgagor irrevocably authorizes all parties obligated to pay Rents to accept any notice from the Mortgagee that Mortgagor’s license to collect the Rents has been terminated after the occurrence and during the continuance of an Event of Default and, following such notice, to follow the instructions of the Mortgagee and ignore the instructions of Mortgagor with respect to collecting the Rents, including instructions which direct the obligors to pay all amounts due directly to the Mortgagee. Upon such notification and at the expense of Mortgagor, the Mortgagee may enforce collection of any Rents, and adjust, settle, or compromise the amount or payment thereof.

     5.5 Account Debtors. Mortgagee may, in its discretion, after the occurrence and during the continuance of any Event of Default, notify any account debtor to make payments directly to Mortgagee and contact account debtors directly to verify information furnished by Mortgagor. Mortgagee shall not have any obligation to preserve any rights against prior parties.

     5.6 Costs and Expenses. All reasonable sums advanced or costs or expenses incurred by Mortgagee (either by it directly or on its behalf by the Trustee or any receiver appointed hereunder) in protecting and enforcing its rights hereunder shall constitute a demand obligation owing by Mortgagor to Mortgagee as part of the Secured Obligations. Mortgagor hereby agrees to repay such reasonable sums on demand plus interest thereon from the date of the advance or incurrence until reimbursement of Mortgagee at the same rate of interest as charged Alternate Base Rate Advances when an Event of Default exists as set forth in the Credit Agreement.

     5.7 Set-Off. Upon the occurrence and during the continuance of any Event of Default, Mortgagee shall have the right to set-off any funds of Mortgagor in the possession of Mortgagee against any amounts then due by Mortgagor to Mortgagee pursuant to this Deed of Trust.

     (a) Successor Trustees. The Trustee may resign in writing addressed to Mortgagee or be removed at any time with or without cause by an instrument in writing duly executed by Mortgagee. In case of the death, resignation or removal of the Trustee, a successor Trustee may be appointed by Mortgagee by instrument of substitution complying with any applicable requirements of law, and in the absence of any requirement, without other formality other than an appointment and designation in writing. The appointment and designation will vest in the named successor Trustee all the estate and title of the Trustee in all of the Mortgaged Property and all of the rights, powers, privileges, immunities and duties hereby conferred upon the Trustee. All references herein to the Trustee will be deemed to refer to any successor Trustee from time to time acting hereunder.

     (b) Indemnification of Trustee. The Trustee shall not be liable for any error of judgment or act done by the Trustee in good faith, or be otherwise responsible or accountable under any circumstances whatsoever, INCLUDING THE TRUSTEE’S OWN NEGLIGENCE, but excluding any of the Trustee’s own gross negligence, bad faith or willful misconduct or arising out of disputes with the Lenders found to be such by a final, non-appealable judgment by a court of competent jurisdiction. The Trustee may rely on any instrument, document, or signature authorizing or supporting any action taken or proposed to be taken by him hereunder, believed by him in good faith to be genuine. All moneys received by the Trustee shall, until used or applied as herein provided, be held in trust for the purposes for which they were received, but need not be segregated in any manner from any other moneys (except to the extent required by law), and the Trustee shall have no liability for interest on any moneys received by him hereunder. Mortgagor shall reimburse the Trustee for, and indemnify and save the Trustee harmless against, any and all liability and expenses which may be incurred by the Trustee in the performance of the Trustee’s duties hereunder, INCLUDING THOSE INCURRED AS A RESULT OF THE TRUSTEE’S OWN NEGLIGENCE, but excluding such liabilities and expenses that are found by a final, non-appealable judgment by a court of competent jurisdiction to have been incurred as a result of the gross negligence, willful misconduct, or

bad faith of the Trustee or arising out of disputes with the Lenders. Mortgagor’s obligations under this Section 6.1(b) shall survive the termination of this Deed of Trust, the payment in full of the Secured Obligations, the termination of all obligations of the Issuing Banks and the Lenders in respect of Letters of Credit, and the termination or expiration of the Commitments.

     (c) Duties of Trustee. It shall be no part of the duty of the Trustee to see to any recording, filing or registration of this Deed of Trust or any other instrument in addition or supplemental hereto, or to see to the payment of or be under any duty with respect to any tax or assessment or other governmental charge which may be levied or assessed on the Mortgaged Property, any part thereof, or against Mortgagor, or to see to the performance or observance by Mortgagor of any of the covenants and agreements contained herein. Trustee shall not be responsible for the execution, acknowledgment or validity of this Deed of Trust or of any instrument in addition or supplemental hereto or for the sufficiency of the security purported to be created hereby, and makes no representation in respect thereof or in respect of the rights of Mortgagee.

Trustee shall not incur any personal liability hereunder except for his own willful misconduct; and the Trustee shall have the right to rely on any instrument, document or signature authorizing or supporting any action taken or proposed to be taken by him hereunder, believed by him in good faith to be genuine.

     6.2 Advances by Mortgagee or Trustee. Each and every covenant of Mortgagor herein contained shall be performed and kept by Mortgagor solely at Mortgagor’s expense. If Mortgagor fails to perform or keep any of the covenants of whatsoever kind or nature contained in this Deed of Trust, Mortgagee (either by it directly or on its behalf by the Trustee or any receiver appointed hereunder) may, but will not be obligated to, make advances to perform the same on Mortgagor’s behalf, and Mortgagor hereby agrees to repay such sums and any reasonable attorneys’ fees incurred in connection therewith on demand plus interest thereon from the date of the advance until reimbursement of Mortgagee at the same rate of interest as charged Alternate Base Rate Advances when an Event of Default exists as set forth in the Credit Agreement. In addition, Mortgagor hereby agrees to repay on demand any costs, expenses and reasonable attorney’s fees incurred by Mortgagee or the Trustee which are to be obligations of Mortgagor pursuant to, or allowed by, the terms of this Deed of Trust, including such costs, expenses and reasonable attorney’s fees incurred pursuant to the terms hereof, plus interest thereon from the date of the advance by Mortgagee or the Trustee until reimbursement of Mortgagee or the Trustee, respectively, at the same rate of interest as charged Alternate Base Rate Advances when an Event of Default exists as set forth in the Credit Agreement. Such amounts will be in addition to any sum of money which may, pursuant to the terms and conditions of the written instruments comprising part of the Secured Obligations, be due and owing. No such advance will be deemed to relieve Mortgagor from any default hereunder.

     6.3 Termination. If the Secured Obligations (including all Letter of Credit Obligations) have been indefeasible paid in full in cash, all Letters of Credit have expired or terminated and all obligations of the Issuing Banks and the Lenders in respect of Letters of Credit have terminated, and all Commitments have expired or terminated, then all of the Mortgaged Property (to the extent not sold pursuant to the terms hereof) will revert to Mortgagor and the entire estate, right, title and interest of the Trustee and Mortgagee will thereupon cease; and Mortgagee in such case shall, upon the request of Mortgagor and the payment by Mortgagor of all reasonable attorneys’ fees and other expenses, deliver to Mortgagor proper instruments acknowledging satisfaction of this Deed of Trust.

     6.4 Renewals, Amendments and Other Security. Without notice or consent of Mortgagor, renewals and extensions of the written instruments constituting part or all of the Secured Obligations may

be given at any time and amendments may be made to agreements relating to any part of such written instruments or the Mortgaged Property. Mortgagee may take or hold other security for the Secured Obligations without notice to or consent of Mortgagor. The acceptance of this Deed of Trust by Mortgagee shall not waive or impair any other security Mortgagee may have or hereafter acquire to secure the payment of the Secured Obligations nor shall the taking of any such additional security waive or impair the Lien and security interests herein granted. The Trustee or Mortgagee may resort first to such other security or any part thereof, or first to the security herein given or any part thereof, or from time to time to either or both, even to the partial or complete abandonment of either security, and such action will not be a waiver of any rights conferred by this Deed of Trust. This Deed of Trust may not be amended, waived or modified except in a written instrument executed by both Mortgagor and Mortgagee.

     6.5 Security Agreement, Financing Statement and Fixture Filing. This Deed of Trust will be deemed to be and may be enforced from time to time as an assignment, chattel mortgage, contract, deed of trust, financing statement, real estate mortgage, or security agreement, and from time to time as any one or more thereof if appropriate under applicable state law. AS A FINANCING STATEMENT, THIS DEED OF TRUST IS INTENDED TO COVER ALL PERSONALTY COLLATERAL INCLUDING MORTGAGOR’S INTEREST IN ALL HYDROCARBONS AS AND AFTER THEY ARE EXTRACTED AND ALL ACCOUNTS ARISING FROM THE SALE THEREOF AT THE WELLHEAD.

In addition, Mortgagor hereby irrevocably authorizes Mortgagee and any affiliate, employee or agent thereof, at any time and from time to time, to file in any Uniform Commercial Code jurisdiction any financing statement or document and amendments thereto, without the signature of Mortgagor where permitted by law, in order to perfect or maintain the perfection of any security interest granted under this Deed of Trust. A photographic or other reproduction of this Deed of Trust shall be sufficient as a financing statement.

     6.6 Unenforceable or Inapplicable Provisions.

     6.7 Rights Cumulative. Each and every right, power and remedy herein given to the Trustee or Mortgagee will be cumulative and not exclusive, and each and every right, power and remedy whether specifically herein given or otherwise existing may be exercised from time to time and as often and in such order as may be deemed expedient by the Trustee, or Mortgagee, as the case may be, and the exercise, or the beginning of the exercise, of any such right, power or remedy will not be deemed a waiver of the right to exercise, at the same time or thereafter, any other right, power or remedy.

It is the intent of Mortgagor and Mortgagee in the execution and performance of this Deed of Trust, the Credit Agreement and the other Credit Documents to contract in strict compliance with applicable usury laws governing the Secured Obligations including such applicable usury laws of the State of Texas and the United States of America as are from time-to-time in effect. In furtherance thereof, Mortgagee and Mortgagor stipulate and agree that none of the terms and provisions contained in this Deed of Trust, the Credit Agreement or the other Credit Documents shall ever be construed to create a contract to pay, as consideration for the use, forbearance or detention of money, interest at a rate in excess of the maximum non-usurious rate permitted by applicable law and that for purposes hereof “interest” shall include the aggregate of all charges which constitute interest under such laws that are contracted for, charged or received under this Deed of Trust, the Credit Agreement and the other Credit Documents; and in the event that, notwithstanding the foregoing, under any circumstances the aggregate amounts taken, reserved, charged, received or paid on the Secured Obligations, include amounts which by applicable law are deemed interest which would exceed the maximum non-usurious rate permitted by applicable law, then such excess shall be deemed to be a mistake and Mortgagee shall credit the same on the principal of the Secured Obligations (or if the Secured Obligations shall have been paid in full, refund said excess to Mortgagor). In the event that the maturity of the Secured Obligations is accelerated by reason of any election of Mortgagee resulting from any Event of Default, or in the event of any required or permitted prepayment, then such consideration that constitutes interest may never include more than the maximum non-usurious rate permitted by applicable law and excess interest, if any, provided for in this Deed of Trust, the Credit Agreement or other Credit Documents shall be canceled automatically as of the date of such acceleration and prepayment and, if theretofore paid, shall be credited on the Secured Obligations or, if the Secured Obligations shall have been paid in full, refunded to Mortgagor. In determining whether or not the interest paid or payable under any specific contingencies exceeds the maximum non-usurious rate permitted by applicable law, Mortgagor and Mortgagee shall to the maximum extent permitted under applicable law amortize, prorate, allocate and spread in equal part during the period of the full stated term of the Secured Obligations, all amounts considered to be interest under applicable law of any kind contracted for, charged, received or reserved in connection with the Secured Obligation.

     6.17 [INTENTIONALLY OMITTED.]

     6.18 No Offsets, Etc. Mortgagor hereby represents, warrants and covenants to Mortgagee and the Trustee that there are no offsets, counterclaims or defenses at law or in equity against this Deed of Trust or the indebtedness secured thereby.

     6.19 Bankruptcy Limitation. Notwithstanding anything contained herein to the contrary, it is the intention of Mortgagor, the Mortgagee and the other Credit Parties that the amount of the Secured Obligation secured by Mortgagor’s interests in any of its Property shall be in, but not in excess of, the maximum amount permitted by fraudulent conveyance, fraudulent transfer and other similar law, rule or regulation of any Governmental Authority applicable to Mortgagor. Accordingly, notwithstanding anything to the contrary contained in this Deed of Trust, in any other agreement or instrument executed in connection with the payment of any of the Secured Obligations, the amount of the Secured Obligations secured by Mortgagor’s interests in any of its Property pursuant to this Deed of Trust shall be limited to an aggregate amount equal to the largest amount that would not render Mortgagor’s obligations hereunder or the Liens and security interest granted to the Mortgagee hereunder subject to avoidance under Section 548 of the United States Bankruptcy Code or any comparable provision of any other applicable law.

     6.20 Express Negligence Rule. The indemnification, release and assumption provisions provided for in this Agreement shall be applicable whether or not the losses, costs, expenses and damages in question arose solely or in part from the gross, active, passive, or concurrent negligence, strict liability or other fault of any indemnified party. Each of Administrative Agent, the Issuing Banks, the Lenders, the Borrower, and each of the Guarantors acknowledges that this statement complies with the express negligence rule and is conspicuous.

     6.21 Time of the Essence. Time is of the essence in the performance of each and every obligation under this Deed of Trust.

     6.22 Financing Statement and Utility Security Instrument Filings. This Deed of Trust may be filed as provided in Article 9 of the UCC, to assure that the security interests granted by this Deed of Trust are perfected. In this connection, this instrument will be presented to a filing officer under the UCC to be filed in the real estate records as a Financing Statement covering fixtures. This Deed of Trust may also be filed as provided in TEX. BUS. & COM. CODE ANN. Ch. 35 (Vernon 1996), as amended from time to time, relating to the granting of a security interest by utilities. The filing of this Deed of Trust under the provisions of TEX. BUS. & COM. CODE ANN, Ch. 35 (Vernon 1996), as amended from time to time, shall not constitute an admission by Mortgagor that it is a utility for purposes of TEX. BUS. & COM. CODE ANN.
