"Affected Lender" has the meaning set forth in Section 2.14(a).

"Affiliate" means, as to any Person, any other Person that, directly or indirectly, through one or more intermediaries, controls, is controlled by or is under common control with such Person or any Subsidiary of such Person. The term "control" (including the terms "controlled by" or "under common control with") means the possession, directly or indirectly, of the power to direct or cause the direction of the management or policies of a Person, whether through ownership of a Control Percentage, by contract or otherwise.

"Aggregate Commitment" means the Commitments of all Lenders.

"Agreement" means this Second Amended and Restated Credit Agreement, as it may be amended, restated, supplemented, renewed, extended or otherwise modified from time to time in accordance with its terms (including, without limitation, as it may be supplemented by any Increase Commitment Agreement).

"Applicable Lending Office" means, with respect to each Lender, such Lender's Domestic Lending Office in the case of a Base Rate Advance and such Lender's Eurodollar Lending Office in the case of a Eurodollar Rate Advance.

"Applicable Margin" means, subject to the terms and provisions of this definition, at any time with respect to any Revolving Advances, facility fees, letter of credit fees or utilization fees hereunder, the following percentages determined as a function of the ratings by the Selected Rating Agencies, applicable on such date, of the Company's Senior Debt as set forth below:


	Senior Debt Rating
Tier				Eurodollar	Base Rate	Facility	Letter of	Utilization
Level	S&P	Moody�s	Fitch	Rate Advances	Advances	Fees	Credit Fees	Fees
I	A or higher	A2 or higher	A or higher	0.190%	0.000%	0.060%	0.190%	0.050%
II	A-	A3	A-	0.230%	0.000%	0.070%	0.230%	0.050%
III	BBB+	Baa1	BBB+	0.295%	0.000%	0.080%	0.295%	0.075%

VI	BB+ or less	Ba1 or less	BB+ or less	0.525%	0.000%	0.200%	0.525%	0.150%

If (with respect to the table above) the Senior Debt Ratings of the Selected Rating Agencies fall within different Tier Levels, the Applicable Margin shall be based on the higher Senior Debt Rating unless the higher Senior Debt Rating is two or more Tier Levels above the lower Senior Debt Rating, in which case the Senior Debt Rating which is the level directly above the lower Senior Debt Rating will apply. If the ratings established by either of the Selected Rating Agencies for the Company's Senior Debt change (other than as a result of a change in the rating system of such Selected Rating Agency), such change shall be effective as of the date on which it is first announced by the applicable Selected Rating Agency. If the rating system of either Selected Rating Agency shall change when a rating for the Company's Senior Debt exists from both Selected Rating Agencies, then such Selected Rating Agency�s, "Senior Debt Rating" as referred to in the table above shall be, if and to the extent objectively determinable, changed to the equivalent new rating with the effect that such change in the rating system shall have no effect on the Applicable Margin that would have been determined under the table above if such rating change had not occurred or, if and to the extent the same is not objectively determinable, then the Applicable Margin shall be based on the rating of the Selected Rating Agency that has not changed its rating system or, if both Selected Rating Agencies have changed their rating system, the Selected Rating Agency as to which the change is objectively determinable or, if the change is not objectively determinable as to either Selected Rating Agency, then the Applicable Margin shall be determined as provided in the last sentence of this definition. If either such Selected Rating Agency shall cease to rate corporate debt obligations of the Company, then the Applicable Margin shall be based on the rating of the Selected Rating Agency that continues to rate the corporate debt obligations of the Company. If both of the Selected Rating Agencies shall change their rating system and the effect thereof is not objectively determinable as explained above, cease rating the Company's Senior Debt or cease to be in the business of rating corporate debt obligations, then the Company and the Administrative Agent shall select a

substitute nationally recognized statistical rating agency or agencies, as the case may be; provided, however, that if the Company and the Administrative Agent cannot mutually agree on such a substitute rating agency, then a substitute nationally recognized statistical rating agency or agencies, as the case may be, shall be selected and approved by the Company, the Administrative Agent and the Majority Lenders; provided, further, however, that if the Company, the Administrative Agent and the Majority Lenders cannot mutually agree on such a substitute rating agency, then the Applicable Margin shall be the rate then most recently determined in accordance with this definition.

ARTICLE II

THE ADVANCES AND THE LETTERS OF CREDIT

Section 2.1 The Advances.

(a) Revolving Advances. Subject to the succeeding proviso, each Lender severally agrees, on the terms and conditions set forth in this Agreement, to make Revolving Advances to the Borrowers from time to time on any Business Day prior to the Maturity Date in an aggregate amount not to exceed at any time outstanding an amount equal to the remainder of such Lender's Commitment minus such Lender's Pro Rata Share of the outstanding Swingline Advances and the Letter of Credit Exposure at such time; provided, however, that the aggregate amount of all outstanding Revolving Advances, all outstanding Swingline Advances and the Letter of Credit Exposure at any time may not exceed the aggregate Commitments at such time. Within the limits of each Lender's Commitment, the Borrowers may from time to time borrow, prepay (in whole or in part) and reborrow Revolving Advances.

(b) Swingline Advances. Subject to the succeeding proviso, on the terms and conditions set forth in this Agreement, the Swingline Lender may, in its sole discretion from time to time on any Business Day during the period from the date of this Agreement until the Maturity Date, make advances ("Swingline Advances") under the Swingline Note to the Borrowers in an aggregate principal amount not to exceed $25,000,000 outstanding at any time; provided, however, that the aggregate amount of all outstanding Revolving Advances, all outstanding Swingline Advances and the Letter of Credit Exposure at any time may not exceed the aggregate Commitments at such time; and provided, further, that no Swingline Advance shall be made by the Swingline Lender if, to its knowledge, the statements set forth in Section 3.2(a) are not true on the date of such Swingline Advance, it being agreed by the Borrowers that the giving of the

applicable Notice of Borrowing and the acceptance by any Borrower of the proceeds of such Swingline Advance shall constitute a representation and warranty by the Borrowers that on the date of such Swingline Advance such statements are true. Subject to the other provisions hereof, the Borrowers may from time to time borrow, prepay (in whole or in part) and reborrow Swingline Advances.

(i) Except as provided in the following clause (ii) below, each request for a Swingline Advance shall be made pursuant to telephone or email notice to the Swingline Lender given no later than 1:00 p.m. (Dallas, Texas time) on the date of the proposed Swingline Advance, promptly confirmed by a completed and executed Notice of Borrowing telecopied to the Administrative Agent. The Swingline Lender will promptly make the Swingline Advance available to the applicable Borrower at such Borrower's account designated in its written notice to the Administrative Agent.

(ii) The Borrowers and the Lenders agree that in the event any Swingline Advance is not repaid on the date due to the Swingline Lender, each Lender shall pay to the Administrative Agent its Pro Rata Share of such Swingline Advance and such payment shall be deemed to be a Base Rate Advance made pursuant to such Lender's Commitment, whether made before or after termination of the Commitments, acceleration of the Advances or otherwise, and whether or not a Default has then occurred or is continuing or any of the other conditions precedent set forth in Article III have been satisfied. The Administrative Agent shall give each Lender notice of such Mandatory Revolving Borrowing by 11:00 a.m. (Dallas, Texas time) on the date the Mandatory Revolving Borrowing is to be made. Each Lender shall make its Advance available to the Administrative Agent for the account of the Swingline Lender in immediately available funds by 1:00 p.m. (Dallas, Texas time) on the date requested, and the Borrowers hereby irrevocably instructs the Swingline Lender to apply the proceeds of such Mandatory Revolving Borrowing to the payment of the outstanding Swingline Advances.

Section 2.2 Method of Borrowing.

(a) Notice. Each Revolving Borrowing shall be made pursuant to a Notice of Borrowing given, not later than (i) 11:00 a.m. (Dallas, Texas time) on the third Business Day before the date of the proposed Borrowing, in the case of a Eurodollar Rate Advance or (ii) 11:00 a.m. (Dallas, Texas time) on the Business Day of the proposed Borrowing, in the case of a Base Rate Advance, by the Borrower requesting such Revolving Borrowing to the Administrative Agent, and on the day of its receipt of a timely Notice of Borrowing, the Administrative Agent shall transmit a copy of such notice to each Lender by telecopier; provided, however, that the Administrative Agent and each of the Lenders hereby waive the requirement in clause (i) of this Section 2.2(a) that any Borrower provide three Business Days advance written notice of the date of the initial Borrowing. Each Swingline Advance shall be made pursuant to a Notice of Borrowing given by the applicable Borrower to each of the Administrative Agent and the Swingline Lender not later than 1:00 p.m. (Dallas, Texas time) on the day of the proposed Borrowing. Each Notice of Borrowing shall be in writing or by telecopier specifying the requested (A) date of such Borrowing, (B) Type of Advances comprising such Borrowing, (C) aggregate amount of such Borrowing, and (D) if such

Borrowing is to be comprised of Eurodollar Rate Advances, the Interest Period for each such Advance. In the case of a proposed Borrowing comprised of Eurodollar Rate Advances, the Administrative Agent shall promptly notify each Lender of the applicable interest rate under Section 2.6(b). Each Lender shall (1) in the case of all Revolving Borrowings other than Borrowings made on the same day as the day the Notice of Borrowing is received, before 1:00 p.m. (Dallas, Texas time) on the date of such Borrowing and (2) in the case of Revolving Borrowings made on the same day as the date of the Notice of Borrowing or Mandatory Revolving Borrowings, before 1:00 p.m. (Dallas, Texas time), make available for the account of its Applicable Lending Office to the Administrative Agent at the Administrative Agent's address referred to in Section 9.2, or such other location as the Administrative Agent may specify by notice to the Lenders, in same day funds, such Lender's Pro Rata Share of such Borrowing. After the Administrative Agent's receipt of such funds and, except in the case of Mandatory Revolving Borrowings, upon fulfillment of the applicable conditions set forth in Article III, the Administrative Agent will make such funds available to the Borrower requesting such funds or, in the case of Mandatory Revolving Borrowings, to the Swingline Lender, in each case at such Borrower's or the Swingline Lender's (as applicable) account designated in its respective written notice to the Administrative Agent.

(b) Conversions and Continuations. In order to elect to Convert or continue Advances comprising part of the same Revolving Borrowing under this Section, the Borrower making such election shall deliver an irrevocable Notice of Conversion or Continuation to the Administrative Agent at the Administrative Agent's office no later than 11:00 a.m. (Dallas, Texas time) (i) on the Business Day of the proposed conversion date in the case of a Conversion of such Advances to Base Rate Advances and (ii) at least three Business Days in advance of the proposed Conversion or continuation date in the case of a Conversion to, or a continuation of, Eurodollar Rate Advances. Each such Notice of Conversion or Continuation shall be in writing or by telecopier, specifying (A) the requested Conversion or continuation date (which shall be a Business Day), (B) the Borrowing amount and Type of the Advances to be Converted or continued, (C) whether a Conversion or continuation is requested and, if a Conversion, into what Type of Advances, and (D) in the case of a Conversion to, or a Continuation of, Eurodollar Rate Advances, the requested Interest Period. Revolving Advances may only be Converted or continued as Revolving Advances. Swingline Advances may not be Converted or continued. Promptly after receipt of a Notice of Conversion or Continuation under this Section 2.2(b), the Administrative Agent shall provide each Lender with a copy thereof and, in the case of a Conversion to or a continuation of Eurodollar Rate Advances, notify each Lender of the applicable interest rate under Section 2.6(b). For purposes other than the conditions set forth in Section 3.2, the portion of Revolving Advances comprising part of the same Revolving Borrowing that are Converted to Revolving Advances of another Type shall constitute a new Revolving Borrowing.

(i) each Borrowing (other than a Borrowing of Swingline Advances) shall be in an aggregate amount not less than (A) $1,000,000 or greater multiples of $500,000, in the case of Eurodollar Rate Advances, or (B) $500,000 or greater multiples of $100,000,

in the case of Base Rate Advances, and shall consist of Advances of the same Type made on the same day by the Lenders ratably according to their respective Commitments;

(ii) at no time shall there be more than eight Interest Periods applicable to outstanding Eurodollar Rate Advances;

(iii) no Borrower may select Eurodollar Rate Advances for any Borrowing to be made if (A) the aggregate amount of such Borrowing is less than $1,000,000 or (B) a Default has occurred and is continuing;

(iv) no Borrower may select Eurodollar Rate Advances for any Borrowing to be Converted or continued if (A) the aggregate amount of such Borrowing is less than $1,000,000 or (B) an Event of Default has occurred and is continuing;

(v) (A) if any Lender shall, at any time prior to the making of any requested Borrowing comprised of Eurodollar Rate Advances, notify the Administrative Agent 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, such Lender's Pro Rata Share of such Borrowing shall be made as a Base Rate Advance of such Lender, but otherwise shall be considered part of the same Borrowing and interest on such Base Rate Advance shall be due and payable at the same time that interest on the Eurodollar Rate Advances comprising the remainder of such Borrowing shall be due and payable; and (B) such Lender agrees to use commercially reasonable efforts (consistent with its internal policies and legal and regulatory restrictions) to designate a different Applicable Lending Office if the making of such designation would avoid the effect of this clause (v) and would not, in the reasonable judgment of such Lender, be otherwise disadvantageous to such Lender;

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

(vii) if the Majority Lenders shall, at least one Business Day before the date of any requested Borrowing, notify the Administrative Agent 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 such Borrower to select Eurodollar Rate Advances for such Borrowing or for any subsequent Borrowing shall be suspended until the Administrative Agent shall notify such Borrower and the Lenders that the circumstances causing such suspension no longer exist, and each Advance comprising such Borrowing shall be a Base Rate Advance; and

(viii) if any Borrower shall fail to select the duration or continuation of any Interest Period for any Eurodollar Rate Advances in accordance with the provisions contained in the definition of "Interest Period" in Section 1.1 and Section 2.2(a) or 2.2(b) above, the Administrative Agent will forthwith so notify such Borrower and the Lenders and such Advances will be made available to such Borrower on the date of such Borrowing as Base Rate Advances or, if an existing Advance, Converted into Base Rate Advances.

(d) Notices Irrevocable. Each Notice of Borrowing and Notice of Conversion or Continuation shall be irrevocable and binding on the Borrowers. In the case of any Borrowing which the related Notice of Borrowing specifies is to be comprised of Eurodollar Rate Advances, the Borrowers shall indemnify each Lender against any loss or out-of-pocket cost or expense incurred by such Lender as a result of any condition precedent for Borrowing set forth in Article III not being satisfied or waived by the Administrative Agent and the Majority Lenders for any reason, including, without limitation, any loss, cost or expense actually 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 Revolving Borrowing or Mandatory Revolving Borrowing that such Lender will 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 2.2(a) and the Administrative Agent may, in reliance upon such assumption, make available to the applicable 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 Borrowers 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 any Borrower until the date such amount is repaid to the Administrative Agent, at (i) in the case of the Borrowers, 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.

(f) Lender 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 2.3 Fees.

(a) Facility Fees. The Borrowers agree to pay to the Administrative Agent, for the pro rata benefit of the Lenders, a facility fee on the average daily aggregate amount of the Commitments, irrespective of the Borrowers' usage of such Commitments, at a rate per annum equal to the Applicable Margin for the period from the Effective Date until the Maturity Date, which fee shall be due and payable quarterly in arrears on the last Business Day of each March, June, September and December and on the Maturity Date.

(b) Letter of Credit Fees.

(i) The Borrowers agree to pay to the Administrative Agent, for the pro rata benefit of the Lenders, a fee in respect of all Letters of Credit outstanding at a rate per annum equal to the Applicable Margin calculated on the average daily maximum amount available from time to time to be drawn under such outstanding Letters of Credit, which fee shall be due and payable quarterly in arrears on the last Business Day of each March, June, September and December and on the Maturity Date.

(ii) Upon agreement by the Company and any Issuing Lender, the Borrowers shall pay to such Issuing Lender, solely for the account of such Issuing Lender, a fronting fee (A) with respect to each Letter of Credit issued by such Issuing Lender, at a rate agreed upon by the Company and such Issuing Lender, which fee shall be due and payable quarterly in arrears on the last Business Day of each March, June, September and December and on the Maturity Date, and (B) with respect to any renewal (including any auto-renewal), extension of the expiry date or amendment (increasing the amount thereof) of any commercial Letter of Credit issued by such Issuing Lender, at a rate and at such time as agreed upon by the Company and such Issuing Lender.

(iii) In addition to the fees referred to in the preceding clauses (i) and (ii) above, the Borrowers agree to pay to each Issuing Lender for its own account amendment, transfer and negotiation fees, in respect of all Letters of Credit outstanding issued by such Issuing Lender, which fees shall be due and payable in such amounts, at such times and otherwise in accordance with such Issuing Lender's then current policy.

(c) Administrative Agent Fees. The Borrowers agree to pay to the Administrative Agent and/or Wells Fargo, for its benefit, the fees set forth in the Administrative Agent's Fee Letter.

(d) Utilization Fee. The Borrowers agree to pay to the Administrative Agent, for the pro rata benefit of the Lenders, a utilization fee at a rate per annum equal to the product of (i) the Applicable Margin and (ii) the aggregate amount of Advances and Letter of Credit Exposure on each day that the aggregate amount of Advances and Letter of Credit Exposure exceeds 50% of the actual daily amount of the Commitments then in effect (or, if terminated, in effect immediately prior to such termination), which fee shall be due and payable quarterly in arrears on the last Business Day of each March, June, September and December and on the Maturity Date.

Section 2.4 Reduction of the Commitments.

(a) Voluntary Reduction. The Borrowers shall have the right, upon at least three Business Days' irrevocable notice to the Administrative Agent, to terminate in whole or reduce ratably in part the unused portion of the Commitments; provided that each partial reduction shall be in the aggregate amount of $1,000,000 or greater multiples of $1,000,000. Subject to Section 2.16, any termination or reduction of the Commitments pursuant to this Section 2.4 shall be permanent, with no obligation of the Lenders to reinstate such Commitments and the facility fees provided for in Section 2.3(a) shall thereafter be computed on the basis of the Commitments, as so reduced.

(b) Change of Control. Upon the occurrence of any of the following:

(i) a change in control is reported by the Company in response to either Item 6(e) of Schedule 14A of Regulation 14A promulgated under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), or

(ii) any "person" or "group" (as such terms are used in Section 13(d) and Section 14(d) of the Exchange Act, but excluding any employee benefit plan of such person or its subsidiaries, and any person or entity acting in its capacity as trustee, agent or other fiduciary or administrator or any such plan) is or becomes the "beneficial owner" (as defined in Rule 13d-3 and 13d-5 under the Exchange Act), directly or indirectly, of voting Capital Stock of the Company (or securities convertible into or exchangeable for such Capital Stock) representing the Control Percentage or more of the combined voting power of the Company's then outstanding Capital Stock,

then, in such event the Majority Lenders may, at their sole option upon written notice to the Company (a "Termination Notice"), declare the obligation of each Lender to make Advances and the obligation of each Issuing Lender to issue, increase or extend Letters of Credit to be terminated, whereupon the same shall forthwith terminate and the Commitments shall reduce to zero.

Section 2.5 Repayment of Advances.

(a) Revolving Advances. The Borrowers shall repay the outstanding principal amount of each Revolving Advance on the Maturity Date.

(b) Swingline Advances. The Borrowers shall repay the outstanding principal amount of each Swingline Advance on the earlier of the Maturity Date or the date which is three Business Days after the date such Swingline Advance was made.

Section 2.6 Interest. The Borrowers shall pay interest on the unpaid principal amount of each Advance from the date of such Advance until such principal amount shall be paid in full, at the following rates per annum:

(a) Base Rate Advances. If such Advance is a Base Rate Advance, a rate per annum equal, at all times, to the lesser of (i) the Base Rate in effect from time to time plus the Applicable Margin and (ii) the Maximum Rate, payable in arrears on the last Business Day of

each calendar quarter and on the date such Base Rate Advance is payable in full, provided that any amount of principal which is not paid when due (whether at stated maturity, by acceleration or otherwise) shall bear interest from the date on which such amount is due until such amount is paid in full, payable on demand, at a rate per annum equal at all times to the lesser of (A) the rate required to be paid on such Advance immediately prior to the date on which such amount becomes due plus two percent (2%) and (B) the Maximum Rate.

(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 lesser of (i) the Eurodollar Rate for such Interest Period plus the Applicable Margin and (ii) the Maximum Rate, payable in arrears on the last day of such Interest Period and on the date such Eurodollar Rate Advance is payable in full; provided, however, in the case of an Interest Period greater than three months, accrued interest shall also be payable on the date that is three months after the first day of such Interest Period; and provided, further, that any amount of principal which is not paid when due (whether at stated maturity, by acceleration or otherwise) shall bear interest from the date on which such amount is due until such amount is paid in full, payable on demand, at a rate per annum equal at all times to the lesser of (A) the greater of (1) the Base Rate in effect from time to time plus two percent (2%) and (2) the rate required to be paid on such Advance immediately prior to the date on which such amount became due plus two percent (2%) and (b) the Maximum Rate.

(c) Swingline Advances. If such Advance is a Swingline Advance, a rate per annum equal, at all times, to the lesser of (i) the rate agreed to pursuant to the letter agreement between the Company and Wells Fargo dated May 4, 2007 and (ii) the Maximum Rate, payable in arrears on the earlier of the Maturity Date of this Agreement or the last Business Day of each calendar quarter and, if a Default has then occurred and is continuing, on the date such Swingline Advance is payable in full, provided that any amount of principal which is not paid when due (whether at stated maturity, by acceleration or otherwise) shall bear interest from the date on which such amount is due until such amount is paid in full, payable on demand, at a rate per annum equal at all times to the lesser of (1) the rate required to be paid on such Advance immediately prior to the date on which such amount becomes due plus two percent (2%) and (2) the Maximum Rate.

(d) Usury Recapture. In the event that, but for limitations regarding the Maximum Rate set forth in this Agreement, the rate of interest otherwise chargeable under this Agreement at any time is greater than the Maximum Rate, then the unpaid principal amount of the Advances shall bear interest at the Maximum Rate until the total amount of interest paid or accrued on the Advances equals the amount of interest which would have been paid or accrued on the Advances if the stated rates of interest set forth in this Agreement, without giving effect to limitations regarding the Maximum Rate set forth in this Agreement, had at all times been in effect. In the event, upon payment in full of the Advances, the total amount of interest paid or accrued under the terms of this Agreement on the Advances is less than the total amount of interest which would have been paid or accrued if the rates of interest set forth in this Agreement, without giving effect to limitations regarding the Maximum Rate set forth in this Agreement, had, at all times, been in effect, then the Borrowers shall, to the extent permitted by applicable law, pay the Administrative Agent for the account of the Lenders an amount equal to the difference between (i) the lesser of (A) the amount of interest which would have been charged on the Advances if

the Maximum Rate had, at all times, been in effect and (B) the amount of interest which would have accrued on the Advances if the rates of interest set forth in this Agreement, without giving effect to limitations regarding the Maximum Rate set forth in this Agreement, had at all times been in effect and (ii) the amount of interest actually paid or accrued under this Agreement on the Advances. In the event the Lenders ever receive, collect or apply as interest any sum in excess of the Maximum Rate, such excess amount shall, to the extent permitted by law, be applied to the reduction of the principal balance of the Advances, and if no such principal is then outstanding, such excess or part thereof remaining shall be paid to the Borrowers.

(e) Default Interest. Notwithstanding anything to the contrary contained in this Agreement, (i) at all times during which an Event of Default has occurred and is continuing, interest shall accrue and be payable on the outstanding principal amount of each Advance, and (ii) to the fullest extent permitted by applicable law and whether or not an Event of Default has occurred and is continuing, interest shall accrue on any other amount of the Obligations which is not paid in full when due (whether at stated maturity, by acceleration or otherwise), in each case payable on demand at a rate per annum equal to the lesser of (A) the Base Rate plus two percent (2%) and (B) the Maximum Rate, which interest at such rate shall accrue from the initial date of the giving of notice by the Administrative Agent to the Company of the occurrence of such Event of Default (as to clause (i) preceding) or from the date such amount of the Obligations became due until the date such amount is paid in full (as to clause (ii) preceding).

Section 2.7 Prepayments.

(a) Right to Prepay. The Borrowers shall have no right to prepay any principal amount of any Advance except as provided in this Section 2.7.

(b) Optional Prepayments. The Borrowers may elect to prepay any of the Advances, after giving notice thereof to the Administrative Agent (i) by 11:00 a.m. (Dallas, Texas time) on the day of prepayment of any Swingline Advance, and (ii) by 11:00 a.m. (Dallas Texas time) at least three Business Days' prior to the day of prepayment of any Eurodollar Rate Advances and at least one Business Day prior to the day of prepayment of any Base Rate Advances. Such notice must state the proposed date and aggregate principal amount of such prepayment, whether such prepayment should be applied to reduce outstanding Revolving Advances or Swingline Advances, and if applicable, the relevant Interest Period for the Advances to be prepaid. If any such notice is given, the Borrowers 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, and shall also pay accrued interest to the date of such prepayment on the principal amount prepaid and amounts, if any, required to be paid pursuant to Section 2.8 as a result of such prepayment being made on such date; provided, however, that each partial prepayment of Eurodollar Rate Advances shall be in an aggregate principal amount not less than $1,000,000 or greater multiples of $500,000.

(i) Change of Control. On the fifth Business Day following the Company's receipt of a Termination Notice pursuant to Section 2.4(b) hereof, the Borrowers shall be required to prepay all outstanding Advances and all other unpaid Obligations in full and

to deposit with the Administrative Agent into the Cash Collateral Account an amount equal to the Letter of Credit Exposure.

(ii) Reduction of Commitments. In the event the Commitments are reduced in accordance with Section 2.4(a), the Borrowers shall prepay the Advances to the extent the aggregate amount of all outstanding Advances and the Letter of Credit Exposure exceeds the aggregate amount of the Commitments after giving effect to such reduction (or, upon payment in full of all outstanding Advances, to deposit with the Administrative Agent into the Cash Collateral Account an amount equal to the amount by which the Letter of Credit Exposure exceeds the Commitments as so reduced).

(iii) Accrued Interest. Each prepayment pursuant to this Section 2.7(c) 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 2.8 as a result of such prepayment being made on such date.

(iv) Avoidance of Breakage Costs. In the event that the amount of any mandatory prepayment of Advances under this Section 2.7(c) exceeds the aggregate principal amount of Advances which consist of Base Rate Advances (the amount of such excess being the "Excess Amount"), the Borrowers shall have the right, in lieu of making such prepayment in full, to prepay such outstanding Advances which are Base Rate Advances and to deposit an amount equal to the Excess Amount with the Administrative Agent in the Cash Collateral Account maintained by and in the sole dominion and control of the Administrative Agent for the ratable benefit of the Lenders. Any amount so deposited shall be held by the Administrative Agent as collateral for the Obligations and applied to the prepayment of Advances which are Eurodollar Rate Advances at the end of the current Interest Period(s) applicable thereto. On any day on which amounts collected in the Cash Collateral Account remain on deposit in or to the credit of the Cash Collateral Account after giving effect to the payment made on such day pursuant to this Section 2.7(c), and the Company shall have delivered to the Administrative Agent a written request or a telephonic request (which shall be promptly confirmed in writing) prior to 10:00 am (Dallas, Texas time) that such remaining collected amounts be invested in cash equivalents specified in such request, the Administrative Agent shall invest such funds, to the extent the Administrative Agent is reasonably able to do so, in such cash equivalents as are acceptable to, and with no risk to, the Administrative Agent on an overnight basis or with maturities such that amounts will be available to pay the Obligations secured thereby as they become due, whether at maturity, by acceleration or otherwise; provided, however, that any loss resulting from such investments shall be charged to and be immediately payable by the Borrowers on demand by the Administrative Agent.

(d) Ratable Payments. Each payment of any Advance pursuant to this Section 2.7 or any other provision of this Agreement shall be made in a manner such that all Advances comprising part of the same Borrowing are paid in whole or ratably in part.

(e) Effect of Notice. All notices given pursuant to this Section 2.7 shall be irrevocable and binding upon the Borrowers.

Section 2.8 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 as a result of any payment pursuant to Section 2.7 or the acceleration of the maturity of the Advances pursuant to Article VII or otherwise, (b) any Conversion of a Eurodollar Rate Advance is made other than on the last day of the Interest Period for such Advance pursuant to Section 2.12 or otherwise, (c) the Borrowers fail to (i) borrow, continue, convert or prepay any Eurodollar Rate Advance on the date specified in any notice delivered pursuant hereto or (ii) make a principal or interest payment with respect to any Eurodollar Rate Advance on the date such payment is due and payable, or (d) the assignment of any Eurodollar Rate Advance other than on the last day of an Interest Period therefor as a result of a request of the Company pursuant to Section 2.14, the Borrowers shall, within 10 days of any written demand sent by any Lender to the Company through the Administrative Agent, pay to the Administrative Agent for the account of such Lender any amounts (without duplication of any other amounts payable in respect of breakage costs) required to compensate such Lender for any additional losses or out-of-pocket costs or expenses which it may reasonably incur as a result of such payment or nonpayment, including, without limitation, any loss (excluding 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 2.9 Increased Costs.

(a) Eurodollar Rate Advances. If, after the date hereof, 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 calculation of the Eurodollar Rate) in or in the interpretation of any law or regulation 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 in the cost to any Lender of agreeing to make or making, funding or maintaining Eurodollar Rate Advances, then the Borrowers shall from time to time, within 30 days of written demand by such Lender (with a copy of such demand to the Administrative Agent), immediately pay to the Administrative Agent for the account of such Lender additional amounts (without duplication of any other amounts payable in respect of increased costs) sufficient to compensate such Lender for such increased cost; provided, however, that, before making any such demand, each Lender agrees to use commercially 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 the reasonable judgment of such Lender, be otherwise disadvantageous to such Lender. In determining such increased costs, each Lender will act reasonably and in good faith and will use averaging and attribution methods which are reasonable, provided that such Lender's reasonable good faith determination (made in a manner generally consistent with the Lender's standard practices) of compensation owing under this Section 2.9(a) shall, absent manifest error, be conclusive and binding for all purposes. Each Lender, at the time such Lender demands payment under this Section 2.9(a), shall submit to the Company and the Administrative Agent a certificate (A) as to the amount of such increased cost, (B) detailing the calculation of such cost, and (C) certifying that such Lender is generally charging such costs to other similarly situated borrowers under similar credit facilities; provided that, unless such Lender is also demanding compensation generally from other similarly situated borrowers of such Lender under

similar credit facilities, the Borrowers shall not be required to compensate such Lender pursuant to this Section 2.9(a) for any increased costs.

(b) Capital Adequacy. If any Lender or any Issuing Lender determines in good faith that compliance with any law or regulation or any guideline or request from any central bank or other Governmental Authority (whether or not having the force of law) implemented or effective after the date of this Agreement affects or would affect the amount of capital required or expected to be maintained by such Lender or such Issuing Lender (or on the amount of capital required or expected to be maintained by such Lender's or the Issuing Lender's holding company) and that the amount of such capital is increased by or based upon the existence of such Lender's commitment to lend or such Issuing Lender's commitment to issue Letters of Credit or any Lender's commitment to risk participate in Letters of Credit and other commitments of this type, then, upon 30 days prior written notice by such Lender or such Issuing Lender (with a copy of any such demand to the Administrative Agent), the Borrowers shall pay to the Administrative Agent for the account of such Lender or to such Issuing Lender, as the case may be, from time to time as specified by such Lender or such Issuing Lender, additional amounts (without duplication of any other amounts payable in respect of increased costs) sufficient to compensate such Lender or such Issuing Lender (or such Lender's or the Issuing Lender's holding company), in light of such circumstances, (i) with respect to such Lender (or holding company), to the extent that such Lender reasonably determines such increase in capital to be allocable to the existence of such Lender's commitment to lend under this Agreement or its commitment to risk participate in Letters of Credit and (ii) with respect to such Issuing Lender (or holding company), to the extent that such Issuing Lender reasonably determines such increase in capital to be allocable to the issuance or maintenance of the Letters of Credit. In determining such additional amounts, each Lender will act reasonably and in good faith and will use averaging and attribution methods which are reasonable, provided that such Lender's reasonable good faith determination (made in a manner generally consistent with the Lender's standard practices) of compensation owing under this Section 2.9(b) shall, absent manifest error, be conclusive and binding for all purposes. Each Lender, at the time such Lender demands payment under this Section 2.9(b), shall submit to the Company and the Administrative Agent a certificate (A) as to the amount of such additional amounts, (B) detailing the calculation of such additional amounts, and (C) certifying that such Lender is generally charging such additional amounts to other similarly situated borrowers under similar credit facilities; provided that, unless such Lender is also demanding compensation generally from other similarly situated borrowers of such Lender under similar credit facilities, the Borrowers shall not be required to compensate such Lender pursuant to this Section 2.9(b) for any additional amounts.

(c) Letters of Credit. If, after the date hereof, 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, any Issuing Lender or any Lender or (ii) impose on such Issuing Lender or any Lender 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 Lender of issuing or maintaining any Letter of Credit, or increase the cost to such Lender of its risk participation in any Letter of Credit (which increase in cost shall be determined by such Issuing Lender's or such

Lender's reasonable allocation of the aggregate of such cost increases resulting from such event), then, within 30 days of written demand by such Issuing Lender or such Lender (with a copy sent to the Administrative Agent), as the case may be, the Borrowers shall pay to the Administrative Agent for the account of such Issuing Lender or such Lender, as the case may be, from time to time as specified by such Issuing Lender or such Lender, additional amounts which shall be sufficient to compensate such Issuing Lender or such Lender for such increased cost. Each Issuing Lender and each Lender agrees to use commercially reasonable efforts (consistent with internal policy and legal and regulatory restrictions) to designate a different Applicable Lending Office for the booking of its Letters of Credit or risk participations if the making of such designation would avoid the effect of this Section 2.9(c) and would not, in the reasonable judgment of such Issuing Lender or such Lender, be otherwise disadvantageous to such Issuing Lender or such Lender, as the case may be. In determining such increased costs, each Lender will act reasonably and in good faith and will use averaging and attribution methods which are reasonable, provided that such Lender's reasonable good faith determination (made in a manner generally consistent with the Lender's standard practices) of compensation owing under this Section 2.9(c) shall, absent manifest error, be conclusive and binding for all purposes. Each Lender, at the time such Lender demands payment under this Section 2.9(c), shall submit to the Company and the Administrative Agent a certificate (A) as to the amount of such increased cost, (B) detailing the calculation of such cost, and (C) certifying that such Lender is generally charging such costs to other similarly situated borrowers under similar credit facilities; provided that, unless such Lender is also demanding compensation generally from other similarly situated borrowers of such Lender under similar credit facilities, the Borrowers shall not be required to compensate such Lender pursuant to this Section 2.9(c) for any increased costs.

Section 2.10 Payments and Computations.

(a) Payment Procedures. Except if otherwise set forth herein, the Borrowers 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 at the location referred to in the Notes (or such other location as the Administrative Agent shall designate in writing to the Company) in same day funds without set-off, counterclaims or other deduction. The Administrative Agent will 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 Issuing Lenders or a specific Lender pursuant to Section 2.1(b), 2.3(b), 2.3(c), 2.3(d), 2.6(c), 2.8, 2.9, 2.11, 2.12 or 2.13(c)) to the Lenders in accordance with each Lender's Pro Rata Share 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 Lender to such Lender or such Issuing 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 or fees based on the Base Rate when the Base Rate is determined by the Prime Rate shall be made on the basis of a year of 365 or 366 days, as the case may be, and the actual days elapsed. Subject to Section 9.12, all other computations of interest or fees based on the Eurodollar Rate or the Federal Funds Rate 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 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 any Borrower prior to the date on which any payment is due to the Lenders that the Borrowers will not make such payment in full, the Administrative Agent may assume that the Borrowers have 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 to such Lender. If and to the extent the Borrowers 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.

(e) Application of Payments. Unless otherwise specified in Section 2.7 hereof, whenever any payment received by the Administrative Agent under this Agreement is insufficient to pay in full all amounts then due and payable under this Agreement and the Notes, such payment shall be distributed and applied by the Administrative Agent and the Lenders in the following order: first, to the payment of fees and expenses due and payable to the Administrative Agent or Wells Fargo under and in connection with this Agreement or any other Credit Document; second, to the payment of all expenses due and payable under Section 2.11(c), ratably among the Lenders in accordance with the aggregate amount of such payments owed to each such Lender; third, to the payment of fees due and payable to the Issuing Lenders pursuant to Section 2.3(b); fourth, to the payment of all other fees due and payable under Section 2.3 ratably among the Lenders in accordance with their applicable Commitments; and fifth, to the payment of the interest accrued on and the principal amount of all of the Advances, Reimbursement Obligations and other Obligations, regardless of whether any such amount is then due and payable, ratably among the Lenders in accordance with the aggregate accrued interest plus the aggregate principal amount owed to such Lender.

(f) Evidence of Debt. The Advances made and Letters of Credit issued by each Lender shall be evidenced by one or more accounts or records maintained by such Lender and by the Administrative Agent in the ordinary course of business. The accounts or records maintained by the Administrative Agent and each Lender shall be conclusive absent manifest error of the amount of the Advances made and Letters of Credit issued by the Lenders to the Borrowers and the interest and payments thereon. Any failure to so record or any error in doing so shall not, however, limit or otherwise affect the obligation of the Borrowers hereunder to pay any amount owing with respect to the Obligations. In the event of any conflict between the accounts and records maintained by any Lender and the accounts and records of the Administrative Agent in

respect of such matters, the accounts and records of the Administrative Agent shall control in the absence of manifest error. Upon the request of any Lender made through the Administrative Agent, the Borrowers shall execute and deliver to such Lender (through the Administrative Agent) a Note, which shall evidence such Lender's Advances in addition to such accounts or records. Each Lender may attach schedules to its Note and endorse thereon the date, Type (if applicable), amount and maturity of its Advances and payments with respect thereto. In addition to the accounts and records referred to in this Section 2.10(f), each Lender and the Administrative Agent shall maintain in accordance with its usual practice accounts or records evidencing the purchases and sales by such Lender of participations in Letters of Credit and Swingline Advances. In the event of any conflict between the accounts and records maintained by the Administrative Agent and the accounts and records of any Lender in respect of such matters, the accounts and records of the Administrative Agent shall control in the absence of manifest error.

Section 2.11 Taxes.

(a) No Deduction for Certain Taxes. Any and all payments by the Borrowers shall be made, in accordance with Section 2.10, 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 Lender and the Administrative Agent, taxes imposed on its income, and franchise taxes imposed on it, by the jurisdiction under the laws of which such Lender, such Issuing Lender or the Administrative Agent (as the case may be) is organized or any political subdivision of such jurisdiction (all such non-excluded taxes, levies, imposts, deductions, charges, withholdings and liabilities being hereinafter referred to as "Taxes") and, in the case of each Lender and each Issuing Lender, Taxes by the jurisdiction of such Lender's Applicable Lending Office or any political subdivision of such jurisdiction. If any Borrower shall be required by law to deduct any Taxes from or in respect of any sum payable to any Lender, any Issuing Lender 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 2.11), such Lender, such Issuing Lender 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; provided, however, that if such Borrower's obligation to deduct or withhold Taxes is caused solely by such Lender�s, such Issuing Lender's or the Administrative Agent's failure to provide the forms described in Section 2.11(e) and such Lender, such Issuing Lender or the Administrative Agent could have provided such forms, no such increase shall be required; (ii) such Borrower shall make such deductions; and (iii) such Borrower shall pay the full amount deducted to the relevant taxation authority or other authority in accordance with applicable law.

(b) Other Taxes. In addition, the Borrowers agree 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").

(c) Indemnification. In addition, the Borrowers agree to indemnify each Lender, each Issuing Lender 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 2.11) paid by such Lender, such Issuing Lender or the Administrative Agent (as the case may be) and any liability (including interest and expenses) arising therefrom or with respect thereto, whether or not such Taxes or Other Taxes were correctly or legally asserted. Each payment required to be made by the Borrowers in respect of this indemnification shall be made by the Borrowers to the Administrative Agent for the benefit of any party claiming such indemnification within 30 days from the date the Company receives written demand detailing the calculation of such amounts therefor from the Administrative Agent on behalf of such Lender, such Issuing Lender or the Administrative Agent. If any Lender, any Issuing Lender or the Administrative Agent receives a refund in respect of any taxes paid by the Borrowers under this Section 2.11(c), such Lender, such Issuing Lender or the Administrative Agent, as the case may be, shall promptly pay to the Borrowers such refund.

(d) Evidence of Tax Payments. The Borrowers will pay prior to delinquency all Taxes payable in respect of any payment. Within 30 days after the date of any payment of Taxes, the Company will furnish to the Administrative Agent, at its address referred to in Section 9.2, the original or a certified copy of a receipt evidencing payment of such Taxes.

(e) Foreign Lender Withholding Exemption. Each Lender and each Issuing Lender that is not incorporated under the laws of the U.S. or a state thereof (a "Non-U.S. Lender") agrees that it will deliver to the Borrowers and the Administrative Agent on the date of this Agreement or upon the effectiveness of any Assignment and Acceptance (i) two duly completed copies of U.S. Internal Revenue Service Form W-8ECI or W-8BEN or, in the case of a Non-U.S. Lender claiming exemption from U.S. federal withholding tax under Section 871(h) or 881(c) of the Code, with respect to payments of "portfolio interest", a statement substantially in the form of Exhibit I hereto, appropriately completed, and a Form W-8BEN, or other equivalent successor form, as appropriate, 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 U.S. federal income taxes and (ii) 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 any Borrower. Each Lender which delivers to the Borrowers and the Administrative Agent a Form W-8ECI or W-8BEN, or other equivalent successor form, as appropriate, further undertakes to deliver to the Borrowers and the Administrative Agent two further copies of such form, or successor applicable forms, or other manner of certification, as the case may be, on or before the date that any such form expires or becomes obsolete or after the occurrence of any event requiring a change in the most recent form previously delivered by it to the Borrowers and the Administrative Agent, and such extensions or renewals thereof as may reasonably be requested by any Borrower and the Administrative Agent certifying in the case of a Form W-8ECI or W-8BEN that such Lender is entitled to receive payments under this Agreement without deduction or withholding of any U.S. 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 such Borrower and the Administrative Agent that it is not capable of receiving payments without any deduction or withholding of U.S. federal income tax, such Lender shall not be required to deliver such forms. The Borrowers shall withhold tax at the rate and in the

manner required by the laws of the U.S. with respect to payments made to a Lender failing to timely provide the requisite Internal Revenue Service forms.

Section 2.12 Illegality. If any Lender shall notify the Administrative Agent and the Company that the introduction of or any change in or in the interpretation of any law or regulation after the date hereof 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, then, notwithstanding anything herein to the contrary, the Company shall, if demanded by such Lender in its notice, no later than 11:00 a.m. (Dallas, Texas time), (a) if not prohibited by law or regulation to maintain such Eurodollar Rate Advances for the duration of the Interest Period, on the last day of the Interest Period for each outstanding Eurodollar Rate Advance of such Lender or (b) if prohibited by law or regulation to maintain such Eurodollar Rate Advances for the duration of the Interest Period, on the second Business Day following its receipt of such notice from such Lender, Convert all Eurodollar Rate Advances of such Lender then outstanding to Base Rate Advances and pay accrued interest on the principal amount Converted to the date of such Conversion and amounts, if any, required to be paid pursuant to Section 2.8 as a result of such Conversion being made on such date. Each Lender agrees to use commercially reasonable efforts (consistent with its internal policies and legal and regulatory restrictions) to designate a different Applicable Lending Office if the making of such designation would avoid the effect of this Section 2.12 and would not, in the reasonable judgment of such Lender, be otherwise disadvantageous to such Lender.

Section 2.13 Letters of Credit.

(a) Issuance. From time to time from the date of this Agreement until three months before the Maturity Date, at the request of any Borrower, each Issuing Lender shall, on any Business Day and on the terms and conditions hereinafter set forth, issue, increase, decrease, amend or extend the expiration date of Letters of Credit for the account of the Borrowers (for the benefit of a Borrower or for the benefit of any of the other Subsidiaries of the Company). No Letter of Credit will be issued, increased or extended (i) if such issuance, increase or extension would cause the Letter of Credit Exposure to exceed the lesser of (a) $150,000,000 or (b) an amount equal to the remainder of (1) the aggregate Commitments minus (2) the aggregate outstanding principal amount of the Revolving Advances and Swingline Advances at such time; (ii) unless such Letter of Credit has an Expiration Date not later than the earlier of (A) one year after the date of issuance thereof or (B) five days before the Maturity Date; (iii) unless such Letter of Credit is in form and substance acceptable to the respective Issuing Lender in its sole discretion; (iv) unless the Borrower requesting such Letter of Credit has delivered to the respective Issuing Lender a completed and executed letter of credit application on such Issuing Lender's standard form, which shall contain terms no more restrictive than the terms of this Agreement; and (v) unless such Letter of Credit, if a standby Letter of Credit, is governed by the ISP or, if a commercial Letter of Credit, the rules of the Uniform Customs and Practice for Documentary Credits, as most recently published by the International Chamber of Commerce at the time of issuance. If the terms of any letter of credit application referred to in the foregoing clause (iv) conflicts with the terms of this Agreement, the terms of this Agreement shall control.

(b) Participations. With respect to each letter of credit described on Schedule 1.1(b), the Borrowers, the Administrative Agent, each Issuing Lender and the Lenders agree that such letters of credit shall constitute Letters of Credit for all purposes of this Agreement and each Lender agrees that it has a participation in the related Letter of Credit Exposure equal to such Lender's Pro Rata Share on the Effective Date. On the date of the issuance or increase of any Letter of Credit on or after the Effective Date, each Issuing Lender shall be deemed to have sold to each other Lender and each other Lender shall have been deemed to have purchased from such Issuing Lender a participation in the Letter of Credit Exposure related to the Letters of Credit issued by such Issuing Lender 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. Each Issuing Lender shall promptly notify each such participant Lender by telex, telephone or telecopy of each Letter of Credit of such Issuing Lender issued, increased or decreased, and the actual dollar amount of such Lender's participation in such Letter of Credit. Each Lender's obligation to purchase participating interests pursuant to this Section 2.13(b) and to reimburse the respective Issuing Lender for such Lender's Pro Rata Share of any payment under a Letter of Credit issued by such Issuing Lender and not reimbursed in full by the Borrowers shall be absolute and unconditional and shall not be affected by any circumstance, including, without limitation, (i) any of the circumstances described in Section 2.13(d) below, (ii) the occurrence and continuance of a Default, (iii) an adverse change in the financial condition of any Borrower or Guarantor, or (iv) any other circumstance, happening or event whatsoever, whether or not similar to any of the foregoing, except for any such circumstance, happening or event constituting or arising from gross negligence or willful misconduct on the part of such Issuing Lender.

(c) Reimbursement. The Borrowers hereby agree to pay on demand to each Issuing Lender in respect of each Letter of Credit issued by such Issuing Lender an amount equal to any amount paid by such Issuing Lender under or in respect of such Letter of Credit. In the event any Issuing Lender makes a payment pursuant to a request for draw presented under a Letter of Credit and such payment is not promptly reimbursed by the Borrowers upon demand, such Issuing Lender shall give notice of such payment to the Administrative Agent and the Lenders, and each Lender shall promptly reimburse such Issuing Lender for such Lender's Pro Rata Share of such payment, and such reimbursement shall be deemed for all purposes of this Agreement to constitute a Base Rate Advance to the Borrower from such Lender. If such reimbursement is not made by any Lender to any Issuing Lender within one Business Day of the day on which such Issuing Lender shall have made payment on any such draw, such Lender shall pay interest thereon to such Issuing Lender at a rate per annum equal to the Federal Funds Rate. Until such Issuing Lender receives such reimbursement by a Lender in respect of such draw, the interest accrued on the amount of such draw to be reimbursed by such Lender shall be for the account of such Issuing Lender. The Borrowers hereby unconditionally and irrevocably authorize, empower and direct the Administrative Agent and the Lenders to record and otherwise treat each payment under a Letter of Credit not immediately reimbursed by the Borrowers as a Borrowing comprised of Base Rate Advances to the Borrowers.

(d) Obligations Unconditional. The obligations of the Borrowers 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, notwithstanding 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 any Borrower or any Lender or any other Person 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 respective Issuing Lender 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 respective Issuing Lender would not be liable therefor pursuant to the following Section 2.13(e);

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

(vi) any other circumstance or happening whatsoever, whether or not similar to any of the foregoing;

provided, however, that nothing contained in this Section 2.13(d) shall be deemed to constitute a waiver of any remedies of any Borrower in connection with the Letters of Credit.

(e) Liability of Issuing Lenders. The Borrowers assume 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 Lender nor any of its Related Parties 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 such Issuing Lender 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

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

except that the Borrowers shall have a claim against such Issuing Lender, and such Issuing Lender shall be liable to, and shall promptly pay to, the Borrowers, to the extent of any direct, as opposed to consequential, damages suffered by the Borrowers which the Borrowers prove were caused by (A) such Issuing Lender's willful misconduct 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 Lender'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, any Issuing Lender 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.

Section 2.14 Lender Replacement.

(a) Right to Replace. The Company shall have the right to replace each Lender affected by a condition under clause (v) of Section 2.2(c), Section 2.9 or Section 2.12 for more than 90 days or each Lender which fails to consent to any extension of the Maturity Date pursuant to Section 2.17 (each such Lender, an "Affected Lender") in accordance with the procedures in this Section 2.14 and provided that no reduction of the total Commitments occurs as a result thereof.

(b) First Right of Refusal; Replacement.

(i) Upon the occurrence of any condition permitting the replacement of a Lender, each Lender which is not an Affected Lender shall have the right, but not the obligation, to elect to increase its respective Commitment by an amount not to exceed the amount of the Commitments of the Affected Lenders, which election shall be made by written notice from each such Lender to the Administrative Agent and the Company given within 30 days after the date such condition occurs specifying the amount of such proposed increase in such Lender's Commitment.

(ii) If the aggregate amount of the proposed increases in Commitments of all such Lenders making such an election is in excess of the Commitments of the Affected Lenders, (A) the Commitments of the Affected Lenders shall be allocated pro rata among such Lenders based on the respective amounts of the proposed increases to Commitments elected by each of such Lenders, and (B) the respective Commitments of such Lenders shall be increased by the respective amounts as so allocated so that, after giving effect to such termination and increases, the aggregate amount of the Commitments of all of the Lenders will be the same as prior to such termination.

(iii) If the aggregate amount of the proposed increases in Commitments of all such Lenders making such an election equals the Commitments of the Affected Lenders, the respective Commitments of such Lenders shall be increased by the respective amounts of their proposed increases so that, after giving effect to such termination and increases, the aggregate amount of the Commitments of all of the Lenders will be the same as prior to such termination.

(iv) If the aggregate amount of the proposed increases in Commitments of all such Lenders making such an election is less than the Commitments of the Affected Lenders, (A) the respective Commitments of such Lenders shall be increased by the respective amounts of their proposed increases, and (B) the Company shall add additional Lenders which are Eligible Assignees to this Agreement to replace such Affected Lenders, which additional Lenders would have aggregate Commitments no greater than those of the Affected Lenders minus the amounts thereof assumed by the other Lenders pursuant to such increases.

(c) Procedure. Any assumptions of Commitments pursuant to this Section 2.14 shall be made by the purchasing Lender or Eligible Assignee and the selling Lender entering into an Assignment and Assumption and by following the procedures in Section 9.6 for adding a Lender. In connection with the increase of the Commitments of any Lender pursuant to the foregoing Section 2.14(b), each Lender with an increased Commitment shall purchase from the Affected Lenders at par such Lender's ratable share of the outstanding Advances of the Affected Lenders and assume such Lender's ratable share of the Affected Lenders' Letter of Credit Exposure.

Section 2.15 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 its Advances or its share of Letter of Credit Obligations in excess of its Pro Rata Share 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 in accordance with the requirements of this Agreement 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 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 Borrowers agree that any Lender so purchasing a participation from another Lender pursuant to this Section 2.15 may, to the fullest extent permitted by law, unless and until rescinded as provided above, 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 Borrowers in the amount of such participation.

Section 2.16 Increase of Commitments. By delivery of an effective Increase Notice to the Administrative Agent (which the Administrative Agent shall promptly distribute to the Lenders), the Company may request an increase of the aggregate amount of the Commitments; provided that (a) the aggregate amount of the Commitments both before and after giving effect to such requested increase shall not exceed $525,000,000, (b) no Default or Event of Default shall have occurred and be continuing or would result therefrom and (c) the Company shall cause to be delivered to the Administrative Agent a commitment (or commitments) from (i) at

least one Lender that commits to lending to the Borrowers more than its then current Commitment (such Lender to be referred to herein as an "Existing Lender" and such amount of its commitment above its then current Commitment to be referred to herein as a "Commitment Supplement") and/or (ii) any other Person that meets the requirements of the definition of "Eligible Assignee" (as defined in Article I hereof) and that commits to lending to the Borrowers and becoming a Lender under this Agreement (such Person to be referred to herein as a "New Lender" and the amount of its commitment to be referred to herein as a "New Commitment") (each Existing Lender and each New Lender to be referred to herein collectively as the "Supplementing Lenders"). Upon receipt of notice from the Administrative Agent to the Lenders and the Company that the Supplementing Lenders have agreed to commit to increase the Commitments by an aggregate amount equal to the Increase Amount (as defined below) and execution and delivery by the Borrowers, the Administrative Agent and the Supplementing Lenders of an Increased Commitment Agreement evidencing such agreement, then (A) the then current aggregate Commitments shall be increased by the Increase Amount, (B) the then current Commitment of each Existing Lender shall be increased by such Existing Lender's Commitment Supplement and (C) each of the New Lenders will be added as a Lender under this Agreement and each such New Lender's Commitment shall be such New Lender's New Commitment. On the effective date of the Increased Commitment Agreement, the Borrowers shall request a Revolving Advance hereunder, which Revolving Advance shall be made by (and only by) the Supplementing Lenders in the appropriate amounts as provided below. The proceeds of such Revolving Advance shall be utilized by the Borrowers to repay the Lenders that did not agree to increase their Commitments, such Revolving Advance and repayment to be in amounts sufficient so that, after giving effect to the Increased Commitment Agreement, the Revolving Advances and the Letter of Credit Exposure shall be held by the Lenders according to their Pro Rata Share of the Commitments as increased in accordance with the Increased Commitment Agreement. The Borrower shall pay any amounts required pursuant to Section 2.8 as a result of any payment of any Eurodollar Rate Advance under this Section 2.16.

Section 2.17 Extensions of the Maturity Date.

(a) Extension. In the manner set forth in this Section 2.17, the Company may request that the Maturity Date be extended (i) up to two times, in each case for a period of one year measured from the Maturity Date in effect or (ii) once for a period no longer than two years measured from the Maturity Date then in effect as of the Effective Date. If the Company wishes to request such an extension of the Maturity Date, it shall give written notice to that effect to the Administrative Agent not less than 60 days prior to the Maturity Date then in effect. The Administrative Agent shall notify each Lender of such request promptly upon its receipt of such notice and shall request that each Lender respond to such request by the Borrower within 21 days of the Administrative Agent's notice to the Lenders. If any Lender does not consent in writing or respond to the Company's request within such 21-day period, then such Lender (a "Refusing Lender") shall be deemed to have rejected such request. If Lenders whose combined Pro Rata Shares equal more than 50% (the "Extension Required Lenders"; each Lender agreeing to extend its Commitment is referred to herein as an "Extending Lender") agree in writing within such 21-day period prior to the Maturity Date then in effect to extend their Commitments, and provided that, on the Maturity Date then in effect (x) the representations and warranties made by the Borrower and any Guarantors in any Credit Document (excluding Section 4.5(b) hereof) are true and correct in all material respects at and as if made as of such date except to the extent they

expressly relate to an earlier date and (y) no Default or Event of Default shall exist or be continuing either prior to or after giving effect thereto and the Company delivers to the Administrative Agent a certificate so stating, then (i) effective on the Maturity Date then in effect the Commitments of the Extending Lenders shall without further action be extended for an additional one-year period (or two-year period, as the case may be), (ii) the term "Maturity Date" shall thenceforth mean, (A) as to the Commitments and Advances of the Extending Lenders, the last day of such additional one-year (or two-year, as the case may be) period and (B) as to the Commitments and Advances of the Refusing Lenders, the Maturity Date in effect prior to such extension (each a "RL Maturity Date"), (iii) subject to the terms of subsection (b) below, the Commitments of the Refusing Lenders shall terminate on the applicable RL Maturity Date and the Advances and other amounts owed to such Lenders shall be due and payable on such date, (iv) subject to the terms of subsection (b) below, on such RL Maturity Date (A) the Aggregate Commitment shall be reduced by an amount equal to the sum of the Commitments of the applicable Refusing Lenders and (B) the Pro Rata Shares of the Extending Lenders shall be reallocated so that the sum of such Pro Rata Shares equal one hundred percent (100%) and (v) if the aggregate Revolving Credit Exposure of all Lenders, after the payment provided for in clause (iii) above, exceeds the Aggregate Commitment (as so reduced) (A) the Borrowers shall pay on such RL Maturity Date Loans in the amount necessary to cause the aggregate Revolving Credit Exposure of all Lenders to equal but not exceed the Aggregate Commitment and (B) if the outstanding Letters of Credit exceed the Aggregate Commitment (as so reduced), the Borrowers shall pay to the Administrative Agent on such RL Maturity Date an amount in immediately available funds equal to the amount by which the outstanding Letters of Credit exceed the Aggregate Commitment, which funds shall be held by the Administrative Agent in the Cash LC Collateral Account. If such extension is not approved in writing by the Extension Required Lenders within such 21-day period, then in effect, the Maturity Date then in effect will be retained.

(b) Company Option. So long as the Extension Required Lenders consent to the extension of the Maturity Date in accordance with the terms of Section 2.17(a), with respect to any Refusing Lender, the Company may, in its own discretion, require such Refusing Lender to assign all of its interests, rights and obligations under this Credit Agreement to one or more assignees (which may be one or more Existing Lenders if any Existing Lender accepts such assignment subject to and in accordance with the provisions of Section 2.14). In such event, the maturity date of the Advances transferred to such assignee shall be the Maturity Date as extended in accordance with Section 2.17(a) above. Such transfer and assignment must occur on or prior to the applicable RL Maturity Date.

(c) Indemnity. The Company shall indemnify each Lender (whether an Extending Lender or Refusing Lender) for any loss or expense payable to such Lender pursuant to Section 2.8 as a result of any extension of the Maturity Date pursuant to this Section 2.17 and any assignment of such Lender's Commitments and Advances or any reallocation of such Lender's Pro Rata Share in connection with such extension.

(d) Amendment Authorization. Each of the Lenders hereby authorizes the Administrative Agent, on its behalf, to enter into an amendment to this Credit Agreement (and the Borrowers hereby agree to enter into any such amendment on terms reasonably acceptable to the Company and the Administrative Agent) to effectuate any extension of the Maturity Date,

reduction of the Aggregate Commitment, repayment of Advances or reallocation of the Pro Rata Shares, in each case as expressly contemplated by the terms of this Section 2.17.

Section 2.18 Agreements regarding Subsidiaries.

(a) Domestic Subsidiaries. The Company agrees that it shall cause each Domestic Subsidiary that is a Material Subsidiary and that is not a Borrower to guarantee the payment and performance of the Obligations pursuant to the Guaranty to be executed by such Subsidiary prior to or substantially concurrent with the Borrower's execution of this Agreement. Contemporaneously with the creation or acquisition of any Domestic Subsidiary after the Closing Date that is a Material Subsidiary but that does not become a Borrower or in the event that any Domestic Subsidiary that was not previously a Material Subsidiary becomes a Material Subsidiary, within ten Business Days after delivery of the Compliance Certificate to the Administrative Agent reflecting such fact and the receipt of the necessary documents for execution from the Administrative Agent, the Company shall (i) cause such Domestic Subsidiary to guarantee the payment and performance of the Obligations by executing and delivering to the Administrative Agent an Accession Agreement, (ii) deliver a certificate covering the same matters described in clause (iii) of Section 3.1(a) with respect to such Domestic Subsidiary and (iii) if requested by the Administrative Agent, deliver an opinion of Borrowers' counsel with respect thereto covering the matters previously opined on with regard to each Guarantor.

Each Lender hereby appoints and authorizes the Administrative Agent to take such action as administrative agent under this Agreement and the other Credit Documents on behalf of such Lender and to exercise such powers under this Agreement and the other Credit Documents as are delegated to the Administrative Agent by the terms hereof and of the other Credit Documents, together with such powers as are reasonably incidental thereto. As to any matters not expressly provided for by this Agreement or any other Credit Document (including, without limitation, enforcement or collection of the Notes), the Administrative Agent shall not be required to exercise any discretion or take any action, but shall be required to act or to refrain from acting (and shall be fully protected in so acting or refraining from acting) upon the instructions of the Majority Lenders, and such instructions shall be binding upon all Lenders and all holders of Notes; provided, however, that the Administrative Agent shall not be required to take any action which exposes the Administrative Agent to personal liability or which is contrary to this Agreement, any other Credit Document or applicable law. The Administrative Agent shall not be subject to any fiduciary or other implied duties, regardless of whether a Default or an Event of Default has occurred and is continuing.

Section 8.2 Administrative Agent's Reliance, Etc. Neither the Administrative Agent nor any of its directors, officers, agents or employees shall be liable for any action taken or omitted to be taken (including the Administrative Agent's own negligence) by it or them under or in connection with this Agreement or the other Credit Documents, except for its or their own gross negligence or willful misconduct.

Section 8.3 Delegation of Duties. The Administrative Agent may perform any and all of its duties and exercise its rights and powers hereunder or under any other Credit Document by or through any one or more sub-agents appointed by the Administrative Agent. The Administrative Agent and any such sub-agent may perform any and all of its duties and exercise its rights and powers by or through their respective Related Parties. The exculpatory provisions of this Article shall apply to any such sub-agent and to the Related Parties of the Administrative Agent and any sub-agent, and shall apply to their respective activities in connection with the syndication of the credit facilities provided for herein as well as activities as Administrative Agent.

Section 8.4 The Administrative Agent and Its Affiliates. With respect to its Commitment, the Advances made by it and the Notes issued to it, the Administrative Agent shall have the same rights and powers under this Agreement as any other Lender and may exercise the same as though it were not the Administrative Agent. The term "Lender" or "Lenders" shall, unless otherwise expressly indicated, include the Administrative Agent in its individual capacity. The Administrative Agent and its Affiliates may accept deposits from, lend money to, act as trustee under indentures of, and generally engage in any kind of business with, the Company or any of its Subsidiaries, and any Person who may do business with or own securities of the Company or any such Subsidiary, all as if the Administrative Agent were not an agent hereunder and without any duty to account therefor to the Lenders.

Section 8.5 Lender Credit Decision. Each Lender acknowledges that it has, independently and without reliance upon the Administrative Agent or any other Lender and based on the financial statements referred to in Section 4.5 and such other documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement. Each Lender also acknowledges that it will, independently and without reliance upon the Administrative Agent 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.

Section 8.6 Indemnification. The Lenders severally agree to indemnify the Administrative Agent and each Issuing Lender and each Related Party of any of the foregoing (to the extent not reimbursed by the Borrowers), according to their respective Pro Rata Shares (determined at the time such indemnity is sought) from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever which may be imposed on, incurred by or asserted against the Administrative Agent, such Issuing Lender or any such Related Party in any way relating to or arising out of this Agreement or any other Credit Document or any action taken or omitted by the Administrative Agent, such Issuing Lender or any such Related Party under this Agreement or any other Credit Document (INCLUDING THE AGENT�S, SUCH ISSUING LENDER's OR SUCH RELATED PARTY's OWN NEGLIGENCE), provided that no Lender shall be liable for any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements resulting from the Administrative Agent�s, such Issuing Lender's or such Related Party's gross negligence or willful misconduct. Without limitation of the foregoing, each Lender agrees to reimburse the Administrative Agent promptly upon demand for its ratable share (determined at the time such reimbursement is sought) of any 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 or any other Credit Document, to the extent that the Administrative Agent is not reimbursed for such expenses by the Borrowers.

The Administrative Agent, the Swingline Lender or any Issuing Lender may resign at any time by giving written notice thereof to the Lenders and the Company and may be removed at any time with or without cause by the Majority Lenders upon receipt of written notice from the Majority Lenders to such effect. Upon receipt of notice of any such resignation or removal, the Majority Lenders shall have the right to appoint a successor Administrative Agent, Swingline Lender or Issuing Lender with, if an Event of Default has not occurred and is not continuing, the consent of the Company, which consent shall not be unreasonably withheld or delayed. If no successor Administrative Agent, Swingline Lender or Issuing Lender shall have been so appointed, and shall have accepted such appointment, within 30 days after the retiring Administrative Agent�s, Swingline Lender's or Issuing Lender's giving of notice of resignation or the Majority Lenders' removal of the retiring Administrative Agent, Swingline Lender or Issuing Lender, then the retiring Administrative Agent, Swingline Lender or Issuing Lender may, on behalf of the Lenders and the Company, appoint a successor Administrative Agent, Swingline Lender or Issuing Lender, which shall be a bank with an office in the United States or an Affiliate of any such bank with an office in the United States and, in the case of the Swingline Lender or an Issuing Lender, a Lender. Upon the acceptance of any appointment as Administrative Agent, Swingline Lender or Issuing Lender by a successor Administrative Agent, Swingline Lender or Issuing Lender, such successor Administrative Agent, Swingline Lender or Issuing Lender shall thereupon succeed to and become vested with all the rights, powers, privileges and duties of the retiring Administrative Agent, Swingline Lender or Issuing Lender, and the retiring Administrative Agent, Swingline Lender or Issuing Lender shall be discharged from its duties and obligations under this Agreement and the other Credit Documents, except that the retiring Issuing Lender shall remain an Issuing Lender with respect

to any Letters of Credit issued by such Issuing Lender and outstanding on the effective date of its resignation or removal and the provisions affecting such Issuing Lender with respect to such Letters of Credit shall inure to the benefit of the retiring Issuing Lender until the termination of all such Letters of Credit. After any retiring Administrative Agent�s, Swingline Lender's or Issuing Lender's resignation or removal hereunder as Administrative Agent, Swingline Lender or Issuing Lender, the provisions of this Article VIII shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Administrative Agent, Swingline Lender or Issuing Lender under this Agreement and the other Credit Documents.

In the case of the pendency of any proceeding under any bankruptcy, insolvency, reorganization or any other similar judicial proceeding relative to any Borrower or any Guarantor, the Administrative Agent (irrespective of whether the principal or any Advance or Letter of Credit Obligations 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 any Borrower) shall be entitled and empowered, by intervention in such proceeding or otherwise

(a) 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 Obligations 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 Lender and the Administrative Agent (including any claim for the reasonable compensation, expenses, disbursements and advances of the Lenders, the Issuing Lenders and the Administrative Agent and their respective agents and counsel and all other amounts due the Lenders, the Issuing Lenders and the Administrative Agent under Sections 2.3, 9.4 and 9.7) allowed in such judicial proceeding; and

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 any Issuing Lender any plan of reorganization, arrangement, adjustment or composition affecting the Obligations or the rights of any Lender or any Issuing Lender to authorize the Administrative Agent to vote in respect of the claim of any Lender or any Issuing Lender in any such proceeding.

Section 8.9 Collateral and Guaranty Matters. The Lenders and the Issuing Lenders irrevocably authorize the Administrative Agent, at its option and in its discretion,

Section 9.3 No Waiver; Remedies. No failure on the part of any Lender, the Administrative Agent or any Issuing Lender to exercise, and no delay in exercising, any right or remedy hereunder or under any Note shall operate as a waiver thereof; nor shall any single or partial exercise of any such right or remedy preclude any other or further exercise thereof or the

Section 9.6 Lender Assignments and Participations.

(a) Assignments. Any Lender may assign to one or more Eligible Assignees all or any portion of its rights and obligations under this Agreement and the other Credit Documents (including, without limitation, all or a portion of its Commitment, the Advances owing to it, the Notes held by it and the participation interest in the Letter of Credit Obligations and Swingline Advances held by it); provided, however, that (i) each such assignment shall be of a constant, and not a varying, percentage of all of such Lender's rights and obligations under this Agreement and the other Credit Documents and shall involve a ratable assignment of such Lender's Commitment and such Lender's Revolving Advances, (ii) the amount of the resulting Commitment and Revolving Advances of the assigning Lender (unless it is assigning all its Commitment) and the assignee Lender pursuant to each such assignment (determined as of the date of the Assignment and Acceptance with respect to such assignment) shall in no event be less than $5,000,000 and shall be an integral multiple of $1,000,000, (iii) each such assignment shall be to an Eligible Assignee, (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 Revolving Note subject to such assignment, and (v) each Eligible Assignee (other than the Eligible Assignee of the Administrative Agent or an Eligible Assignee which is an Affiliate of the assigning Lender) shall pay to the Administrative Agent a $3,000 administrative fee. 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 unless otherwise agreed by the parties to

such Assignment and Acceptance and the Administrative Agent, (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 (but such Lender shall continue to be entitled to the benefits of Sections 2.8, 2.9, 2.11(c), 9.4 and 9.7 with respect to facts and circumstances occurring prior to the effective date of such assignment) 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). Notwithstanding anything herein to the contrary, any Lender may assign, as collateral or otherwise, any of its rights under the Credit Documents to any Federal Reserve Lender.

(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 any other Credit Document or the execution, legality, validity, enforceability, genuineness, sufficiency or value of this Agreement or any other Credit Document 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 Company or its Subsidiaries or the Guarantors or the performance or observance by any Borrower or Guarantors of any of its respective obligations under this Agreement or any other Credit Document 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 4.5 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 and the other Credit Documents as are delegated to the Administrative Agent by the terms hereof or thereof, 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 Schedule 9.2 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"). The entries in the Register shall be conclusive and binding for all purposes, absent manifest error, and the Borrowers, the Administrative Agent, the Issuing Lenders 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 Borrowers 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, together with the Revolving Note or, in the case of an assignment to another Lender, Revolving 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 Company. Within five Business Days after its receipt of such notice, the Borrowers, at their own expense, shall execute and deliver to the Administrative Agent in exchange for such Note or Notes, a new Revolving Note payable to the order of such Eligible Assignee in amount equal to the Commitment assumed by it pursuant to such Assignment and Acceptance, and if the assigning Lender has retained any Commitment hereunder, a new Revolving Note payable to the order of such Lender in an amount equal to, respectively, the Commitment retained by it hereunder. Such new Notes shall be dated the effective date of such Assignment and Acceptance and shall otherwise be in substantially the form of the attached Exhibit G.

(e) Electronic Execution of Assignments. The words "execution," "signed," "signature," and words of like import in any Assignment and Acceptance shall be deemed to include electronic signatures or the keeping of records in electronic form, each of which shall be of the same legal effect, validity or enforceability as a manually executed signature or the use of a paper-based recordkeeping system, as the case may be, to the extent and as provided for in any applicable law, including the Federal Electronic Signatures in Global and National Commerce Act, the New York State Electronic Signatures and Records Act, or any other similar state laws based on the Uniform Electronic Transactions Act.

(f) Participations. Each Lender may sell participations to one or more banks or other entities in or to all or a portion of its rights and obligations under this Agreement (including, without limitation, all or a portion of its Commitment, the Advances owing to it, its participation interest in the Letter of Credit Obligations and Swingline Advances and the Revolving Note held by it); provided, however, that (i) such Lender's obligations under this Agreement (including, without limitation, its Commitment to the Borrowers 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 Note for all purposes of this Agreement, (iv) the Borrowers, the Administrative Agent, the Issuing Lenders 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, (v) such Lender shall not require the participant's consent to any matter under this Agreement, except for change in the principal amount of any Note in which the participant has an interest, reductions in fees or interest or extending the Maturity Date, and (vi) such Lender shall give prompt prior notice to the Company of each such participation to be sold by such Lender. The Borrowers hereby agree that participants shall have the same rights under Sections 2.8, 2.9, 2.11(c) and 9.7 hereof as the Lender to the extent of their respective participations. Notwithstanding the foregoing, upon the receipt of notice by the Company of the sale of a participation by any Lender to one or more banks or other entities (other than an Affiliate of such Lender) in or to all or a portion of its rights and obligations under this Agreement (each such bank or other entity, a "Proposed Participant"), the Company shall have the right, but not the obligation, to select additional banks to replace such Proposed Participant on the same terms and conditions as the Proposed Participant upon prompt written notice from the Company to the Administrative Agent and the Lender selling

such participation. The Company shall have ten days from the date of its receipt of notice of the proposed sale of such participation to the Proposed Participant to select replacement banks to replace such Proposed Participant. If the Company does not select any replacement banks or does not elect replacement banks the applicable Lender may sell such participation to the Proposed Participant.

Section 9.7 Indemnification. The Borrowers shall indemnify the Administrative Agent, the Lenders (including any lender which was a Lender hereunder prior to any full assignment of its Commitment), the Issuing Lenders and each Related Party of any of the foregoing Persons (each such Person being called an "Indemnitee") from, and discharge, release and hold each of them harmless against, any and all losses, penalties, liabilities, claims or damages to which any Indemnitee may become subject, insofar as such losses, penalties, liabilities, claims or damages arise out of or result from (a) the execution or delivery of this Agreement or any other Credit Document or any agreement or instrument contemplated hereby or thereby, the performance by the parties hereto of their respective obligations hereunder or thereunder or the consummation of the transactions contemplated hereby or thereby, (b) any Advance or Letter of Credit or any actual or proposed use by any Borrower or any Affiliate of any Borrower of the proceeds of any Advance, (c) any breach by any Borrower, any Subsidiary of any Borrower or any Guarantor of any provision of this Agreement or any other Credit Document, (d) any investigation, litigation or other proceeding (including any threatened investigation or proceeding) relating to the foregoing, or (e) any Environmental Claim or requirement of Environmental Laws concerning or relating to the present or previously-owned or operated properties, or the operations or business, of the Company or any of its Subsidiaries, and the Borrowers shall reimburse each Indemnitee, upon demand, for any reasonable out-of-pocket expenses (including reasonable legal fees) 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 ANY INDEMNITEE's OWN NEGLIGENCE, BUT EXCLUDING ANY SUCH LOSSES, LIABILITIES, CLAIMS, DAMAGES OR EXPENSES INCURRED BY REASON OF THE GROSS NEGLIGENCE, OR WILLFUL MISCONDUCT OR BAD FAITH OF ANY INDEMNITEE.

Section 9.8 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. Except as provided in Section 3.1, this Agreement shall become effective when it shall have been executed by the Administrative Agent and the Administrative Agent shall have received counterparts hereof that, when taken together, bear the signatures of each of the other parties hereto. Delivery of an executed counterpart of a signature page of this Agreement by telecopy or other electronic transmission shall be effective as delivery of a manually executed counterpart of this Agreement.

Section 9.9 Survival of Representations, Etc. All representations and warranties contained in this Agreement or made in writing by or on behalf of the Borrowers 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 Lenders, none of which investigations shall diminish any Lender's right to rely on such representations and

warranties. All obligations of the Borrowers provided for in Sections 2.8, 2.9, 2.11(c), 9.4 and 9.7 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.

Section 9.11 Commercial Loans. The Borrowers represent and warrant that the Advances are and shall be "Commercial Loans" as such term is used in Chapter 306 of the Texas Finance Code. In the event that applicable law provides for an interest ceiling under Chapter 303 of the Texas Finance Code, the ceiling shall be the indicated (weekly) ceiling and shall be used when appropriate in determining the Maximum Rate.

Section 9.12 Usury Not Intended. It is the intent of the Borrowers and each Lender 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 each Lender including such applicable laws of the State of Texas and the U.S. from time to time in effect. In furtherance thereof, the Lenders and the Borrowers 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 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 each Lender receiving same shall credit the same on the principal of its Advances (or if such Advances shall have been paid in full, refund said excess to the Borrowers). In the event that the maturity of the Advances 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 applicable Advances (or, if the applicable Advances shall have been paid in full, refunded to the Borrowers). The provisions of this Section 9.12 shall control over all other provisions of this Agreement or the other Credit Documents which may be in apparent conflict herewith.

Section 9.13 Governing Law. This Agreement, the Notes and the other Credit Documents shall be governed by, and construed and enforced in accordance with, the laws of the State of Texas; provided, that the Administrative Agent and each Lender shall retain all rights arising under federal law.

Section 9.14 Lenders not in Control. None of the covenants or other provisions contained in the Credit Documents shall, or shall be deemed to, give the Lenders the right or power to exercise control over the affairs and/or management of the Company, any of its

Subsidiaries or any Guarantor, the power of the Lenders being limited to the right to exercise the rights and remedies provided in the Credit Documents; provided, however, that if any Lender becomes the owner of any stock, or other equity interest in, any Person whether through foreclosure or otherwise, such Lender shall be entitled (subject to requirements of law) to exercise such legal rights as it may have by being owner of such stock, or other equity interest in, such Person.

Section 9.15 Headings Descriptive. The headings of the several sections, clauses and paragraphs of the Agreement are inserted for convenience only and shall not in any way affect the meaning or construction of any provision of this Agreement.

Section 9.16 WAIVERS OF JURY TRIAL. THE BORROWERS, THE AGENT AND THE LENDERS HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVE TRIAL BY JURY IN ANY LEGAL PROCEEDING RELATING TO THIS AGREEMENT OR THE NOTES OR ANY OTHER CREDIT DOCUMENT OR TO ANY COUNTERCLAIM THEREIN.

EACH BORROWER IRREVOCABLY AND UNCONDITIONALLY SUBMITS, FOR ITSELF AND ITS PROPERTY, TO THE NONEXCLUSIVE JURISDICTION OF THE COURTS OF THE STATE OF TEXAS SITTING IN DALLAS COUNTY AND OF THE UNITED STATES DISTRICT COURT OF THE NORTHERN DISTRICT OF TEXAS, AND ANY APPELLATE COURT FROM ANY THEREOF, IN ANY ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT OR ANY OTHER CREDIT DOCUMENT, OR FOR RECOGNITION OR ENFORCEMENT OF ANY JUDGMENT, AND EACH OF THE PARTIES HERETO IRREVOCABLY AND UNCONDITIONALLY AGREES THAT ALL CLAIMS IN RESPECT OF ANY SUCH ACTION OR PROCEEDING MAY BE HEARD AND DETERMINED IN SUCH TEXAS STATE COURT OR, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, IN SUCH FEDERAL COURT. EACH OF THE PARTIES HERETO 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 AGREEMENT OR IN ANY OTHER CREDIT DOCUMENT SHALL AFFECT ANY RIGHT THAT THE ADMINISTRATIVE AGENT, ANY LENDER OR ANY ISSUING LENDER MAY OTHERWISE HAVE TO BRING ANY ACTION OR PROCEEDING RELATING TO THIS AGREEMENT OR ANY OTHER CREDIT DOCUMENT AGAINST ANY BORROWER OR ITS PROPERTIES IN THE COURTS OF ANY JURISDICTION.

(b) WAIVER OF VENUE. EACH BORROWER IRREVOCABLY AND UNCONDITIONALLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY OBJECTION THAT IT MAY NOW OR HEREAFTER HAVE TO THE LAYING OF VENUE OF ANY ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT OR ANY OTHER CREDIT DOCUMENT IN ANY COURT REFERRED TO IN PARAGRAPH (a) OF THIS SECTION. EACH OF THE PARTIES HERETO HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT

PERMITTED BY APPLICABLE LAW, THE DEFENSE OF AN INCONVENIENT FORUM TO THE MAINTENANCE OF SUCH ACTION OR PROCEEDING IN ANY SUCH COURT.

(c) SERVICE OF PROCESS. EACH PARTY HERETO IRREVOCABLY CONSENTS TO SERVICE OF PROCESS IN THE MANNER PROVIDED FOR NOTICES IN SECTION 9.2. NOTHING IN THIS AGREEMENT WILL AFFECT THE RIGHT OF ANY PARTY HERETO TO SERVE PROCESS IN ANY OTHER MANNER PERMITTED BY APPLICABLE LAW.

Section 9.18 Confidentiality. Each of the Administrative Agent, the Issuing Lenders and the Lenders agrees to maintain the confidentiality of the Information (as defined below), except that Information may be disclosed (a) to it and its Related Parties and accountants and legal counsel, who, in the reasonable judgment of the Administrative Agent and the applicable Lenders, need to know such information for the purpose of performing or exercising the duties, obligations, rights and remedies of the Administrative Agent, the Issuing Lenders or such Lenders under this Agreement and the other Credit Documents (it being understood that the Persons to whom such disclosure is made will be informed of the confidential nature of such Information and instructed to keep such Information confidential), (b) to the extent requested by any regulatory authority, (c) to the extent required by applicable laws or regulations or by any subpoena or similar legal process, (d) to any other party hereto, (e) in connection with the exercise of any remedies hereunder or under any other Credit Document or any action or proceeding relating to this Agreement or any other Credit Agreement or the enforcement of rights hereunder or thereunder, (f) subject to any agreement containing provisions substantially the same as those of this Section, to (i) any assignee of or participant in, or any prospective assignee or participant in, any of its rights or obligations under this Agreement or (ii) any actual or prospective counterparty (or its advisors) to any swap or derivative transaction relating to the Borrowers and their respective obligations, (g) with the consent of the Company, or (h) to the extent such Information (x) becomes publicly available other than as a result of a breach of this Section or (y) becomes available to the Administrative Agent, any Issuing Lender or any Lender on a non-confidential basis from a source other than the Company. In addition, the Administrative Agent, the Issuing Lenders and the Lenders may disclose the existence of this Agreement and the terms of this Agreement to market data collectors, similar service providers to the lending industry, and service providers to the Administrative Agent, the Issuing Lenders and the Lenders in connection with the administration and management of this Agreement and the other Credit Documents. For purposes of this Section, "Information" means all information received from or on behalf of the Company or any other Borrowers or Guarantors relating to the Company or any other Borrowers or Guarantors or any of their respective businesses, including information posted to Intralinks, other than any such information that is available to the Administrative Agent, the Issuing Lenders or any Lender on a non-confidential basis prior to disclosure by the Company or any other Borrowers or Guarantors. Any Person required to maintain the confidentiality of Information as provided in this Section shall be considered to have complied with its obligation to do so if such Person has exercised the same degree of care to maintain the confidentiality of such Information as such Person should accord to its own confidential information.

Each of the Administrative Agent, the Lenders and the Issuing Lenders acknowledges, and shall advise all Persons to whom it discloses Information, that (a) the Information may

include material non-public information concerning the Company or a Subsidiary, as the case may be, (b) it has developed compliance procedures regarding the use of material non-public information and (c) it will, and all persons to whom such information is disclosed should, handle such material non-public information in accordance with applicable law, including United States Federal and state securities laws.

Section 9.19 Joint and Several Obligations.

(a) Joint and Several. Each Borrower shall be jointly and severally liable for all of the obligations of Borrowers under this Agreement, regardless of which Borrower actually receives the proceeds of the Advances or the benefit of any other extensions of credit hereunder, or the manner in which the Borrowers, Administrative Agent, or Lenders account therefor in their respective books and records.

(b) Benefits. Each Borrower acknowledges that it will enjoy significant benefits from the business conducted by the other Borrowers because of, inter alia, their combined ability to bargain with other Persons including without limitation, their ability to receive the credit extensions under this Agreement and the other Credit Documents, which would not have been available to an individual Borrower acting alone. Each Borrower has determined that it is in its best interest to procure the credit facilities contemplated hereunder, with the credit support of the other Borrowers as contemplated by this Agreement and the other Credit Documents.

(c) Inducement. The Administrative Agent and the Lenders have advised the Borrowers that it is unwilling to enter into this Agreement and the other Credit Documents and make available the credit facilities extended hereby or thereby to any Borrower unless each Borrower agrees, among other things, to be jointly and severally liable for the due and proper payment of the Obligations of each other Borrower under this Agreement and the other Credit Documents. Each Borrower has determined that it is in its best interest and in pursuit of its purposes that it so induce the Administrative Agent and the Lenders to extend credit pursuant to this Agreement and the other Credit Documents (i) because of the desirability to each Borrower of the credit facilities hereunder and the interest rates and the modes of borrowing available hereunder, (ii) because each Borrower may engage in transactions joint with other Borrowers, and (iii) because each Borrower may require, from time to time, access to funds under this Agreement for the purposes herein set forth. Each Borrower, individually, expressly understands, agrees and acknowledges, that the credit facilities contemplated hereunder would not be made available on the terms herein in the absence of the collective credit of the Borrowers, the joint and several liability of all such Persons. Accordingly, each Borrower individually acknowledges that the benefit of the accommodations made under this Agreement to Borrowers as a whole constitutes reasonably equivalent value, regardless of the amount of the indebtedness actually borrowed by, advanced to, or the amount of credit provided to, any individual Borrower.

(d) Limitation. Notwithstanding anything herein, in the Notes or in any other Credit Document to the contrary, in any action or proceeding involving any state corporate law, or any state or federal bankruptcy, insolvency, reorganization or other law affecting the rights of credits generally, if, as a result of applicable law relating to fraudulent conveyance or fraudulent transfer, including Section 548 of the Bankruptcy Code or any applicable provisions of

comparable state law (collectively, "Fraudulent Transfer Laws"), the obligations of any Borrower other than the Company (a "Non-Company Borrower") under this Agreement, the Notes or any other Credit Document would otherwise, after giving effect to (i) all other liabilities of such Non-Company Borrower, contingent or otherwise, that are relevant under such Fraudulent Transfer Laws (specifically excluding, however, any liabilities of such Non-Company Borrower in respect of intercompany Indebtedness to any other Borrower to the extent that such Indebtedness would be discharged in an amount equal to the amount paid by such Non-Company Borrower hereunder or under any other Credit Document) and (ii) the value as assets of such Non-Company Borrower (as determined under the applicable provisions of such Fraudulent Transfer Laws) of any rights of subrogation, contribution, reimbursement, indemnity or similar rights held by such Non-Company Borrower, be held or determined to be void, invalid or unenforceable, or subordinated to the claims of any other creditors, on account of the amount of its liability under this Agreement, the Notes or any other Credit Document, then the amount of such liability shall, without any further action by such Non-Company Borrower, any Lender, the Administrative Agent or any other Person, be automatically limited and reduced to the highest amount that is valid and enforceable and not subordinated to the claims of other creditors as determined in such action or proceeding.

(e) Authority. The Administrative Agent is hereby authorized, without notice or demand and without affecting the liability of any Borrower hereunder, to, at any time and from time to time, subject to Section 9.1, (i) renew, extend or otherwise increase the time for payment of the Obligations; (ii) with the written agreement of any Borrower accelerate or otherwise change the terms relating to the Obligations or otherwise modify, amend or change the terms of any promissory note or other agreement, document or instrument now or hereafter executed by any Borrower and delivered to Administrative Agent; (iii) accept partial payments of the Obligations; (iv) take and hold security or collateral for the payment of the Obligations or for the payment of any guaranties of the Obligations and exchange, enforce, waive and release any such security or collateral; (v) apply such security or collateral and direct the order or manner of sale thereof as Administrative Agent, in its sole discretion, may determine; and (vi) settle, release, compromise, collect or otherwise liquidate the Obligations and any security or collateral therefor in any manner, without affecting or impairing the obligations of any Borrower. Except as specifically provided in this Agreement or any of the other Credit Documents, Administrative Agent shall have the exclusive right to determine the time and manner of application of any payments or credits, whether received from any Borrower or any other source, and such determination shall be binding on all Borrowers. All such payments and credits may be applied, reversed and reapplied, in whole or in part, to any of the Obligations as Administrative Agent shall determine in its sole discretion without affecting the validity or enforceability of the Obligations of any other Borrower.

(f) Obligations Unconditional. Each Borrower hereby agrees that, except as hereinafter provided, its obligations hereunder shall be unconditional, irrespective of (i) the absence of any attempt to collect the Obligations from any obligor or other action to enforce the same; (ii) the waiver or consent by Administrative Agent with respect to any provision of any instrument evidencing the Obligations, or any part thereof, or any other agreement heretofore, now or hereafter executed by a Borrower (other than the Borrower with respect to which such waiver or consent is granted) and delivered to Administrative Agent; (iii) failure by Administrative Agent to take any steps to perfect and maintain its security interest in, or to

preserve its rights to, any security or collateral for the Obligations; (iv) the institution of any proceeding under the United States Bankruptcy Code, or any similar proceeding, by or against a Borrower or Administrative Agent's election in any such proceeding of the application of Section 1111(b)(2) of the United States Bankruptcy Code; (v) any borrowing or grant of a security interest by a Borrower as debtor-in-possession, under Section 364 of the United States Bankruptcy Code; (vi) the disallowance, under Section 502 of the United States Bankruptcy Code, of all or any portion of Administrative Agent's claim(s) for repayment of any of the Obligations; or (vii) any other circumstance other than payment in full of the Obligations which might otherwise constitute a legal or equitable discharge or defense of a guarantor or surety.

(g) Remedies Delayed. Until all Obligations have been paid and satisfied in full and all Commitments hereunder are terminated, no payment made by or for the account of a Borrower including, without limitation, (i) a payment made by such Borrower on behalf of the liabilities of any other Borrower or (ii) a payment by any other person under any guaranty, shall entitle such Borrower, by subrogation or otherwise, to any payment from any other Borrower or from or out of any other Borrower's property and such Borrower shall not exercise any right or remedy against any other Borrower or any property of any other Borrower by reason of any performance of such Borrower of its joint and several obligations hereunder.

(h) Notice. Any notice given by one Borrower hereunder shall constitute and be deemed to be notice given by all Borrowers, jointly and severally. Notice given by Administrative Agent or Lenders to the Company hereunder or pursuant to any other Credit Documents in accordance with the terms hereof shall constitute notice to each and every Borrower. The knowledge of one Borrower shall be imputed to all Borrowers and any consent by one Borrower shall constitute the consent of and shall bind all Borrowers.

(i) Rights. This Section is intended only to define the relative rights of Borrowers and nothing set forth in this Section is intended to or shall impair the obligations of Borrowers, jointly and severally, to pay any amounts as and when the same shall become due and payable in accordance with the terms of this Agreement or any other Credit Documents. Nothing contained in this Section shall limit the liability of any Borrower to pay the credit facilities made directly or indirectly to that Borrower and accrued interest, fees and expenses with respect thereto or which such Borrower shall be primarily liable.

(j) Contribution Rights. The parties hereto acknowledge that any rights of contribution and indemnification or a Borrower against another Borrower shall constitute assets of each Borrower to which such contribution and indemnification is owing. The rights of any indemnifying Borrower against the other Borrowers shall be exercisable upon the full and indefeasible payment of the Obligations and the termination of the credit facilities hereunder.

(k) Primary Obligation. This Agreement is a primary and original obligation of each of the Borrowers and each of the Borrowers shall be liable for all existing and future Obligations of any other Borrower as fully as if such Obligations were directly incurred by such Borrower.

(l) Additional Authorizations. Each Borrower, as joint and several primary obligor of the Obligations directly incurred by any other Borrower, authorizes Administrative Agent (subject to Section 9.1), without giving notice to such Borrower or to any other Borrower or

obtaining such Borrower's consent or any other Borrower's consent and without affecting the liability of such Borrower for the Obligations directly incurred by the other Borrower, from time to time to:

(i) compromise, settle, renew, extend the time for payment, change the manner or terms of payment, discharge the performance of, decline to enforce, or release all or any of the Obligations; grant other indulgences to any Borrower in respect thereof; or modify in any manner any documents relating to the Obligations;

(ii) declare all Obligations due and payable upon the occurrence and during the continuance of an Event of Default;

(iii) take and hold security for the performance of the Obligations of any Borrower and exchange, enforce, waive and release any such security;

(iv) apply and reapply such security and direct the order or manner of sale thereof as Administrative Agent, in its sole discretion, may determine;

(v) release, surrender or exchange any deposits or other property securing the Obligations or on which Administrative Agent at any time may have a Lien; release, substitute or add any one or more endorsers or guarantors of the Obligations of any other Borrower; or compromise, settle, renew, extend the time for payment, discharge the performance of, decline to enforce, or release all or any obligations of any such endorser or guarantor or other Person who is now or may hereafter be liable on any Obligations or release, surrender or exchange any deposits or other property of any such Person;

(vi) apply payments received by Administrative Agent from any Borrower to any Obligations, in such order as Administrative Agent shall determine, in its sole discretion; and

(vii) exercise, in its sole discretion, any right, remedy or combination thereof which may then be available to Administrative Agent, since it is such Borrower's intent that the Obligations be absolute, independent and unconditional obligations of such Borrower under all circumstances.

(m) No Impairment. Each Borrower further agrees that its obligations hereunder shall not be impaired in any manner whatsoever by any bankruptcy, extensions, moratoria or other relief granted to any other Borrower pursuant to any statute presently in force or hereafter enacted.

Section 9.20 Amendment and Restatement. Upon satisfaction of all of the conditions precedent set forth in Section 3.1 of this Agreement, the Existing Credit Agreement shall be amended and restated by this Agreement, provided that this Agreement does not constitute and shall not be construed as a novation of or a payment and readvance of the loan principal, interest and other sums, if any, heretofore outstanding under the Existing Credit Agreement.

SCHEDULE 1.1(d)

Company Election Provisions

Notwithstanding anything to the contrary in the Credit Agreement:

1.		"Company Election Charge" means "***"

2.		"***"

3.		"***"

4.		Implementation of a Company Election shall not constitute a Termination Event or be a Reportable Event, shall be excluded from the representations set forth in Section 4.11, and shall not trigger an Event of Default under Section 7.1(g).

5.		Promptly upon the knowledge of any Responsible Officer of the Company, the Company shall furnish the Administrative Agent notice that a Company Election will occur and the proposed date for such Company Election.

6.		"Company Election". Under the provisions of the Taft-Hartley Act, retirement benefits for ABF's contractual employees are provided by a number of Multiemployer Plans. ABF contributes to these Multiemployer Plans monthly based on the time worked by its contractual employees, as specified in the National Master Freight Agreement and its regional supplemental agreements. ABF has contingent liabilities for its share of the unfunded liabilities of each Multiemployer Plan to which it contributes. Under the Multi-Employer Pension Plan Amendments Act of 1980, ABF's contingent liability for a Multiemployer Plan would become payable if it were to withdraw from that Multiemployer Plan. In order to provide single employer retirement benefits for such contractual employees through its own qualified Plan, the Company and/or ABF must withdraw from the Multiemployer Plans and pay its withdrawal liabilities. In order to withdraw from the Multiemployer Plans, ABF must negotiate an agreement with the representative of its contractual employees that allows it to withdraw and establish a single employer retirement Plan or Plans. The Company and/or ABF's election to withdraw from one or more Multiemployer Plans is referred to collectively as the "Company Election". The Company Election may occur in one or more separate Multiemployer Plan withdrawals, all of which individually and collectively constitute the Company Election.

7.		"***"

8.		Information regarding a Company Election shall not be disclosed to any third party (except as otherwise required by law) including, but not limited to, market data collectors, similar service providers to the lending industry, and service providers to the Administrative Agent, the Issuing Lenders and the Lenders without the express written permission of the Company.

Litigation

Litigation.

Various legal actions, the majority of which arise in the normal course business of the Borrowers and their Subsidiaries, are pending. None of these actions, if decided against the Borrowers or their Subsidiaries, would cause a Material Adverse Change. The Borrowers and their Subsidiaries maintain liability insurance against risks arising out of the normal course of its business, subject to certain self-insured retention or deductible limits.

Environmental.

Certain Borrowers and their Subsidiaries, store fuel for their tractors and trucks in approximately 72 underground storage tanks located in 23 states. Maintenance of such tanks is regulated at the federal and, in some cases, state levels. The Borrowers and their Subsidiaries believe they are in substantial compliance with all such regulations. Neither the Company, the Borrowers nor any of their Subsidiaries is aware of any leaks from such tanks that could reasonably be expected to have a Material Adverse Effect on the Borrowers or any of their Subsidiaries.

Certain Borrowers have received notices from the Environmental Protection Agency ("EPA") and others that they have been identified as a potentially responsible party ("PRP") under the Comprehensive Environmental Response Compensation and Liability Act ("CERCLA") or other federal or state environmental statutes at twenty-five sites in the United States. After investigating the Borrowers' and their Subsidiaries' involvement at such sites, the Borrowers and its Subsidiaries have agreed to de minimus settlements aggregating approximately $130,000 over the last ten years at seven of the sites. At December 31, 2006, the Borrowers had accrued approximately $1.2 million to provide for environmental related liabilities.

Insurance Disclosure

Reliance Insurance Company ("Reliance") was the Company's excess insurer for workers' compensation claims above the self-insured retention level of $0.3 million for the 1993 through 1999 policy years. According to an Official Statement by the Pennsylvania Insurance Department on October 3, 2001, Reliance was determined to be insolvent. The Company has been in contact with and has received either written or verbal confirmation from a number of state guaranty funds that they will accept excess claims. For claims not accepted by state guaranty funds, the Company has continually maintained liabilities since 2001 for its estimated exposure to the Reliance liquidation. The Company anticipates receiving either full reimbursement from state guaranty funds or partial reimbursement through orderly liquidation; however, this process could take several years.

Kemper Insurance Companies ("Kemper") insured the Company's workers' compensation excess claims above $0.3 million for the 2000 through 2001 policy years. In March 2003, Kemper announced that it was discontinuing its business of providing insurance coverage. Lumbermen's Mutual Casualty Company, the Kemper company which insures the Company's excess claims, received audit opinions with a going-concern explanatory paragraph on its 2005, 2004 and 2003 statutory financial statements. The Company has not received any communications from Kemper regarding any changes in the handling of the Company's existing excess insurance coverage with Kemper. Although Kemper continues to pay amounts owed, the Company is uncertain as to the future impact that Kemper's financial condition will have on excess insurance coverage during the 2000 and 2001 policy years. Based upon Kemper's available financial information, the Company has recorded an allowance for uncollectible receivables and additional liabilities for excess claims.

SUBSIDIARY GUARANTY AND CONTRIBUTION AGREEMENT

This Subsidiary Guaranty and Contribution Agreement dated as of ___, 2007 (this "Agreement") is executed by the parties signatory hereto or to an Accession Agreement in favor of the Administrative Agent and the Lenders party to the Credit Agreement herein described.

INTRODUCTION

A. This Agreement is given in connection with the Second Amended and Restated Credit Agreement dated as of May 4, 2007 (as the same may be amended, restated, supplemented, renewed, extended or otherwise modified from time to time, the "Credit Agreement") among Arkansas Best Corporation, ABF Aviation, LLC, ABF Cartage, Inc., ABF Farms, Inc., ABF Freight System, Inc., Arkansas Best Airplane Leasing, Inc., Data-Tronics Corp., FleetNet America, Inc., Freightvalue, Inc., Global Supply Chain Services, Inc., Transport Realty, Inc., Tread-Ark Corporation, Tread-Ark Investment Corporation, and Tread-Ark Real Estate Corporation, (collectively, the "Borrowers"), Wells Fargo Bank, National Association, as Administrative Agent (the "Administrative Agent"), Bank of America, N.A. and SunTrust Bank, as Co-Syndication Agents, Wachovia Bank, National Association and The Bank of Tokyo-Mitsubishi UFJ, Ltd., as Co-Documentation Agents, and the lenders parties thereto.

B. The Company is the principal financing entity for all capital requirements of its Subsidiaries, and from time to time the Company has made and will continue to make capital contributions and advances to certain of its Subsidiaries, including each of the parties hereto (such parties herein called individually a "Guarantor" and collectively the "Guarantors"). Each Guarantor is a direct or indirect subsidiary of the Company and will derive substantial direct and indirect benefit from the transactions contemplated by the Credit Agreement.

C. Under the Credit Agreement, it is a condition to the making of the Advances by the Lenders and the issuance of the Letters of Credit by the Issuing Lenders that each Guarantor shall have executed and delivered this Agreement.

Therefore, in order to induce the Lenders to make the Advances and the Issuing Lenders to issue the Letters of Credit, each Guarantor hereby agrees as follows:

Section 1. Definitions. Unless otherwise defined in this Agreement, capitalized terms used herein shall have the same meanings herein as defined in the Credit Agreement.

Section 2. Guaranty. Each Guarantor hereby unconditionally guarantees the punctual payment when due, whether at stated maturity, by acceleration or otherwise, of all indebtedness, liabilities and/or obligations of the Borrowers now or hereafter existing under the Credit Agreement, the Notes and any other Credit Document, whether for principal, Reimbursement Obligations, interest, fees, expenses or otherwise (such indebtedness, liabilities and/or obligations being hereinafter referred to as the "Guaranteed Obligations"), and any and all expenses (including reasonable counsel fees and expenses) incurred by the Administrative Agent or any Lender in enforcing any rights under this Agreement. Each Guarantor agrees that its

Exhibit C to Credit Agreement � Page 1

guaranty obligation under this Agreement is a guarantee of payment, not of collection, and that such Guarantor is primarily liable for the payment of the Guaranteed Obligations.

Section 3. Limit of Liability. Each Guarantor shall be liable under this Agreement with respect to the Guaranteed Obligations only for amounts aggregating up to the largest amount that would not render its guaranty obligation hereunder subject to avoidance under Section 548 of the United States Bankruptcy Code or any comparable provisions of any state law.

Section 4. Guaranty Absolute. Each Guarantor guarantees that the Guaranteed Obligations will be paid strictly in accordance with the terms of the Credit Agreement and the other Credit Documents, regardless of any law, regulation or order now or hereafter in effect in any jurisdiction affecting any of such terms or the rights of the Administrative Agent or the Lenders with respect thereto. The liability of each Guarantor under this Agreement shall be absolute and unconditional irrespective of:

(a) any lack of validity or enforceability of the Credit Agreement, any other Credit Document or any other agreement or instrument relating thereto;

(b) any change in the time, manner or place of payment of, or in any other term of, any of the Guaranteed Obligations, or any other amendment or waiver of or any consent to departure from the Credit Agreement or any Credit Document;

(c) any release or amendment or waiver of or consent to departure from the Credit Agreement, this Agreement or any other agreement or guaranty, for any of the Guaranteed obligations; or

(d) any other circumstances which might otherwise constitute a defense available to, or a discharge of, any Borrower or a Guarantor.

Section 5. Continuation and Reinstatement, Etc. Each Guarantor agrees that, to the extent that the Borrowers make payment to the Administrative Agent or any Lender and such payments 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 occurred. The Guarantor shall defend and indemnify the Administrative Agent and each Lender from and against any claim or loss under this Section 5 (including reasonable attorneys' fees and expenses) in the defense of any such action or suit.

Section 6. Certain Waivers.

6.01. Notice. Each Guarantor hereby waives promptness, diligence, notice of acceptance, notice of acceleration, notice of intent to accelerate and any other notice with respect to any of the Guaranteed Obligations and this Agreement.

6.02. Other Remedies. Each Guarantor hereby waives any requirement that the Administrative Agent or any Lender exhaust any right or take any action against any Borrower or any other Person, including any action required by Chapter 34 of the Texas Business and Commerce Code.

Exhibit C to Credit Agreement � Page 2

6.03. Waiver of Subrogation. (a) Each Guarantor hereby irrevocably waives, until payment in full of all Guaranteed Obligations and termination of all Commitments, any claim or other rights which it may acquire against any Borrower that arise from such Guarantor's obligations under this Agreement or any other Credit Document, including, without limitation, any right of subrogation (including, without limitation, any statutory rights of subrogation under Section 509 of the Bankruptcy Code, 11 U.S.C. 509, or otherwise), reimbursement, exoneration, contribution, indemnification or any right to participate in any claim or remedy of the Administrative Agent or any Lender against any Borrower which the Administrative Agent or any Lender now has or acquires. If any amount shall be paid to any Guarantor in violation of the preceding sentence and the Guaranteed Obligations shall not have been paid in full and all of the Commitments terminated, such amount shall be held in trust for the benefit of the Administrative Agent and the Lenders, and shall promptly be paid to the Administrative Agent for the benefit of the Administrative Agent and the Lenders to be applied to the Guaranteed Obligations, whether matured or unmatured, as the Administrative Agent may elect. Each Guarantor acknowledges that it will receive direct and indirect benefits from the financing arrangements contemplated by the Credit Agreement and that the waiver set forth in this Section 6.03(a) is knowingly made in contemplation of such benefits.

(a) Each Guarantor further agrees that it will not enter into any agreement providing, directly or indirectly, for any contribution, reimbursement, repayment or indemnity by any Borrower or any other Person on account of any payment by such Guarantor to the Administrative Agent or the Lenders under this Agreement.

Section 7. Representations and Warranties. Each Guarantor hereby represents and warrants as follows:

7.01. Legal Authority. Such Guarantor is a corporation or a limited liability company duly organized, validly existing and in good standing under the laws of the jurisdiction of its organization, which is set forth on Schedule 4.1 to the Credit Agreement. The execution, delivery and performance by such Guarantor of this Agreement are within such Guarantor's corporate powers, have been duly authorized by all necessary corporate or other legal action, and do not contravene or violate (a) such Guarantor's charter or bylaws or other organizational document or (b) any law or material contractual restriction affecting such Guarantor or its Property.

7.02. Government Approval. No authorization or approval or other action by, and no notice to or filing with, any Governmental Authority is required for the due execution, delivery and performance by such Guarantor of this Agreement.

7.03. Binding Obligations. This Agreement is the legal, valid and binding obligation of such Guarantor enforceable against such Guarantor in accordance with its terms, subject to the effect of any applicable bankruptcy, insolvency, reorganization, moratorium or similar law affecting creditors' rights (whether considered in a proceeding at law or in equity).

Section 8. Covenants. Each Guarantor will comply with all covenant provisions of Article V and Article VI of the Credit Agreement to the extent such provisions are applicable to a Subsidiary of the Borrower.

Exhibit C to Credit Agreement � Page 3

Section 9. Contribution. As a result of the transactions contemplated by the Credit Agreement, each of the Guarantors will benefit, directly and indirectly, from the Obligations and in consideration thereof desire to enter into a contribution agreement among themselves as set forth in this Section 9 to allocate such benefits among themselves and to provide a fair and equitable arrangement to make contributions in the event any payment is made by any Guarantor hereunder to the Administrative Agent or the Lenders (such payment being referred to herein as a "Contribution"). The Guarantors hereby agree as follows:

9.01. Calculation of Contribution. In order to provide for just and equitable contribution among the Guarantors in the event any Contribution is made by a Guarantor (a "Funding Guarantor"), such Funding Guarantor shall be entitled to a contribution from certain other Guarantors for all payments, damages and expenses incurred by that Funding Guarantor in discharging any of the Obligations, in the manner and to the extent set forth in this Section 9.01. The amount of any Contribution under this Agreement shall be equal to the payment made by the Funding Guarantor to the Administrative Agent or any other beneficiary pursuant to this Agreement and shall be determined as of the date on which such payment is made.

9.02. Benefit Amount Defined. For purposes of this Agreement, the "Benefit Amount" of any Guarantor as of any date of determination shall be the net value of the benefits to such Guarantor and all of its Subsidiaries (including any Subsidiaries which may be Guarantors) from extensions of credit made by the Lenders to the Borrowers under the Credit Agreement; provided, that in determining the contribution liability of any Guarantor which is a Subsidiary to its direct or indirect parent corporation or of any Guarantor to its direct or indirect Subsidiary, the Benefit Amount of such Subsidiary and its Subsidiaries, if any, shall be subtracted in determining the Benefit Amount of the parent corporation. Such benefits shall include benefits of funds constituting proceeds of Advances made to the Borrowers by the Lenders which are in turn advanced or contributed by the Borrowers to such Guarantor or its Subsidiaries and benefits of Letters of Credit issued pursuant to the Credit Agreement on behalf of, or the proceeds of which are advanced or contributed or otherwise benefit, directly or indirectly, such Guarantor and its Subsidiaries (collectively, the "Benefits"). In the case of any proceeds of Advances or Benefits advanced or contributed to a Person of which any of the equity interests are owned directly or indirectly by a Guarantor (an "Owned Entity"), the Benefit Amount of a Guarantor with respect thereto shall be that portion of the net value of the benefits attributable to Advances or Benefits equal to the direct or indirect percentage ownership of such Guarantor in its Owned Entity.

9.03. Contribution Obligation. Each Guarantor shall be liable to a Funding Guarantor in an amount equal to the greater of (a) (i) the ratio of the Benefit Amount of such Guarantor to the total amount of Obligations, multiplied by (ii) the amount of Obligations paid by such Funding Guarantor and (b) 95% of the excess of the fair saleable value of the property of such Guarantor over the total liabilities of such Guarantor (including the maximum amount reasonably expected to become due in respect of contingent liabilities) determined as of the date on which the payment made by a Funding Guarantor is deemed made for purposes of this Agreement (giving effect to all payments made by other Funding Guarantors as of such date in a manner to maximize the amount of such contributions).

Exhibit C to Credit Agreement � Page 4

9.04. Allocation. In the event that at any time there exists more than one Funding Guarantor with respect to any Contribution (in any such case, the "Applicable Contribution"), then payment from other Guarantors pursuant to this Agreement shall be allocated among such Funding Guarantors in proportion to the total amount of the Contribution made for or on account of the Borrowers by each such Funding Guarantor pursuant to the Applicable Contribution. In the event that at any time any Guarantor pays an amount under this Agreement in excess of the amount calculated pursuant to clause (a) of Section 9.03, that Guarantor shall be deemed to be a Funding Guarantor to the extent of such excess and shall be entitled to contribution from the other Guarantors in accordance with the provisions of this Section 9.04.

9.05. Subsidiary Payment. The amount of contribution payable under this Section 9.05 by any Guarantor shall be reduced by the amount of any contribution paid hereunder by a Subsidiary of such Guarantor.

9.06. Equitable Allocation. If as a result of any reorganization, recapitalization or other corporate change in the Company or any of its Subsidiaries, or as a result of any amendment, waiver or modification of the terms and conditions of other Sections of this Agreement or the Obligations, or for any other reason, the contributions under this Section 9.06 become inequitable as among the Guarantors, the Guarantors shall promptly modify and amend this Section 9.06 to provide for an equitable allocation of contributions. Any of the foregoing modifications and amendments shall be in writing and signed by all Guarantors.

9.07. Asset of Party to Which Contribution is Owing. The Guarantors acknowledge that the right to contribution hereunder shall constitute an asset in favor of the Guarantor to which such contribution is owing.

9.08. Subordination. No payments payable by a Guarantor pursuant to the terms of this Section 9 shall be paid until all amounts then due and payable by the Borrowers to any Lender, pursuant to the terms of the Credit Documents, are paid in full in cash. Nothing contained in this Section 9 shall affect the indebtedness, liabilities or obligations of any Guarantor to the Administrative Agent or any Lender under this Agreement, the Credit Agreement or any other Credit Documents.

Section 10. Miscellaneous.

10.01. Addresses for Notices. All notices and other communications provided for hereunder shall be in writing, including telegraphic communication, and delivered or teletransmitted to the Administrative Agent, as set forth in the Credit Agreement, and to each Guarantor, at the address set forth beside such Guarantor's name on Annex 1 hereto or in the Accession Agreement executed by such Guarantor, or to such other address as shall be designated by any Guarantor or the Administrative Agent in written notice to the other parties. All such notices and other communications shall be effective when delivered or teletransmitted to the above addresses.

10.02. Amendments, Etc. No waiver of any provision of this Agreement nor consent to any departure by any Guarantor therefrom shall be effective unless the same shall be in writing and signed by the Administrative Agent, the Majority Lenders and the Borrowers, and no

Exhibit C to Credit Agreement � Page 5

amendment of this Agreement shall be effective unless the same shall be in writing and signed by each Guarantor and the Administrative Agent, with the consent of the Majority Lenders; provided, however, that any amendment or waiver releasing any Guarantor from any liability hereunder shall be signed by all the Lenders; provided, further, however, that any waiver or consent shall be effective only in the specific instance and for the specific purpose for which given. Notwithstanding the foregoing, in the event that any Subsidiary of the Company hereafter is required in a accordance with the terms of the Credit Agreement or otherwise agrees to become a guarantor of the Borrowers' obligations under the Credit Documents, then such Subsidiary may become a party to this Agreement by executing an Accession Agreement ("Accession Agreement") in the form attached hereto as Annex 2, and each Guarantor and the Administrative Agent hereby agrees that, upon such Subsidiary's execution of such Accession Agreement, this Agreement shall be deemed to have been amended to make such Person a Guarantor hereunder for all purposes and a party hereto and no signature is required on behalf of the other Guarantors or the Administrative Agent to make such an amendment to this Agreement effective.

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

10.04. Right of Set-Off. Upon the occurrence and during the continuance of any Event of Default, the Administrative Agent and the Lenders are hereby authorized at any time, to the fullest extent permitted by law, to set off and apply any deposits (general or special, time or demand, provisional or final) and other indebtedness owing by the Administrative Agent or the Lenders to the account of any Guarantor against any and all of the obligations of such Guarantor under this Agreement, irrespective of whether or not the Administrative Agent or the Lenders shall have made any demand under this Agreement and although such obligations may be contingent and unmatured. The Administrative Agent and the Lenders agree promptly to notify each Guarantor affected by any such set-off after any such set-off and application made by the Administrative Agent or the Lenders provided that the failure to give such notice shall not affect the validity of such set-off and application. The rights of the Administrative Agent and the Lenders under this Section 10.04 are in addition to other rights and remedies (including, without limitation, other rights of set-off) which the Administrative Agent and the Lenders may have.

10.05. Continuing Guaranty; Transfer of Interest. This Agreement shall create a continuing guaranty and shall (a) remain in full force and effect until payment in full and termination of the Guaranteed Obligations, (b) be binding upon each Guarantor, its successors, and assigns, and (c) inure, together with the rights and remedies of the Administrative Agent hereunder, to the benefit of the Administrative Agent, the Lenders and their respective successors, transferees and assigns. Without limiting the generality of the foregoing clause, when any Lender assigns or otherwise transfers any interest held by it under the Credit Agreement or other Credit Document to any other Person pursuant to the terms of the Credit Agreement or other Credit Document, that other Person shall thereupon become vested with all the benefits held by such Lender under this Agreement. Subject to Section 5, upon the payment in full and termination of the Guaranteed Obligations, the guaranties granted hereby shall

Exhibit C to Credit Agreement � Page 6

terminate and all rights hereunder shall revert to each Guarantor to the extent such rights have not been applied pursuant to the terms hereof. Subject to Section 5, upon any such termination, the Administrative Agent will, at each Guarantor's expense, execute and deliver to such Guarantor such documents as such Guarantor shall reasonably request and take any other actions reasonably requested to evidence or effect such termination.

10.06. Governing Law. This Agreement shall be governed by, and construed and enforced in accordance with, the laws of the State of Texas.

10.07. WAIVERS OF JURY TRIAL. EACH GUARANTOR HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES TRIAL BY JURY IN ANY LEGAL PROCEEDING RELATING TO THIS AGREEMENT OR ANY OTHER CREDIT DOCUMENT TO WHICH IT IS A PARTY OR TO ANY COUNTERCLAIM THEREIN.

(b) Any and all Liens (including any judgment Liens) upon any Debtor's property or assets securing payment of any Subordinated Indebtedness (the "Subordinated Liens") shall be and remain inferior and subordinate to any and all Liens, if any exist, upon any Debtor's assets securing payment of the Guaranteed Obligations or any part thereof, regardless of whether such Subordinated Liens presently exist or are hereafter created or when such Subordinated Liens were created, perfected, filed or recorded. Each Guarantor shall not exercise or enforce any creditors' rights or remedies that it may have against any Debtor or foreclose, repossess, sequester or otherwise institute any action or proceeding (whether judicial or otherwise, including, without limitation, the commencement of, or joinder in, any bankruptcy, insolvency, reorganization, liquidation, receivership or other debtor relief law) to enforce any Subordinated Lien on any property or assets of any Debtor unless and until the Guaranteed Obligations shall have been irrevocably paid and performed in full;

(c) In the event of any receivership, bankruptcy, reorganization, rearrangement, debtor's relief or other insolvency proceeding involving any Debtor as debtor, the Administrative Agent shall have the right to prove and vote any claim under the Subordinated Indebtedness and to receive directly from the receiver, trustee or other court custodian all dividends, distributions and payments made in respect of the Subordinated Indebtedness until the Guaranteed Obligations have been irrevocably paid and performed in full. The Administrative Agent may apply any such dividends, distributions and payments against the Guaranteed Obligations in accordance with the Credit Agreement;

(d) All promissory notes, accounts receivable, ledgers, records or any other evidence of Subordinated Indebtedness, and all mortgages, deeds of trust, security agreements, assignments and other security documents evidencing the Subordinated Liens, shall contain a specific written notice thereon that the indebtedness and Liens evidenced thereby are subordinated under the terms of this Agreement; and

(e) The terms and provisions of this Section 10.10 are given by each Guarantor as additional rights, remedies and benefits to any and all other subordination agreements heretofore, concurrently herewith or hereafter executed by such Guarantor to or in favor of the Administrative Agent or any Lender, and nothing in this Agreement shall ever be deemed to in any way negate or replace any other such previous, concurrent or subsequent subordination agreements.

FORM OF BORROWERS�/GUARANTORs' COUNSEL OPINION

, 2007

To Each of the Lenders Party to the Credit
Agreement and Wells Fargo Bank,
National Association, as administrative
agent for the Banks

Ladies and Gentlemen:

I have acted as counsel to Arkansas Best Corporation, a Delaware corporation, ABF Aviation, LLC, an Arkansas limited liability company, ABF Cartage, Inc., a Delaware corporation, ABF Farms, Inc., an Arkansas corporation, ABF Freight System, Inc., a Delaware corporation, Arkansas Best Airplane Leasing, Inc., an Arkansas corporation, Data-Tronics Corp., an Arkansas corporation, FleetNet America, Inc., an Arkansas corporation, Freightvalue, Inc., an Arkansas corporation, Global Supply Chain Services, Inc., an Arkansas corporation, Transport Realty, Inc., an Arkansas corporation, Tread-Ark Corporation, a Delaware corporation, Tread-Ark Investment Corporation, a Nevada corporation, Tread-Ark Real Estate Corporation, a Delaware corporation (collectively, the "Borrowers"), in connection with the Second Amended and Restated Credit Agreement dated as of May 4, 2007 (the "Credit Agreement"), among the Borrowers, the lending institutions party thereto (the "Lenders"), Bank of America, N.A. and SunTrust Bank, as Co-Syndication Agents, Wachovia Bank, National Association and The Bank of Tokyo-Mitsubishi UFJ, Ltd., as Co-Documentation Agents, and Wells Fargo Bank, National Association, as administrative agent for the Lenders (the "Administrative Agent"). I have been requested to render this opinion pursuant to Section 3.1(a)(iv) of the Credit Agreement. Unless otherwise defined herein, capitalized terms used herein shall have the same meanings herein as defined in the Credit Agreement.

In connection with this opinion, I have examined and relied upon the originals, or copies certified or otherwise identified to my satisfaction, of such corporate documents and records of the Borrowers and have received such information from officers and representatives of the Borrowers as I have deemed necessary or appropriate to enable me to express the opinions expressed below. I have also relied on certificates of officers of the Borrowers and certificates of public officials as to certain factual matters. For purposes of this opinion, I have also examined each of the Credit Documents.

In rendering my opinion, I have assumed (a) the genuineness of all signatures, (b) the authenticity of all documents submitted to me as originals, (c) the conformity to authentic original documents of all documents submitted to me as certified, conformed or photostatic copies, and (d) the due authorization, execution and delivery of all documents referred to herein by the parties thereto other than the Borrowers.

Exhibit J to Credit Agreement � Page 1

Based on the foregoing and subject to the further assumptions, qualifications and limitations set forth below, and as may be disclosed in the Credit Documents, I am of the opinion that:

1. Each of the Borrowers is a corporation duly incorporated or limited liability company duly organized, validly existing and in good standing under the laws of the jurisdictions of its incorporation or organization (as applicable).

2. Each of the Borrowers has the requisite power to own or hold under lease its assets and to carry on its businesses as now being conducted and as proposed to be conducted.

3. Each of the Borrowers is duly qualified as a foreign entity and is authorized to do business in each jurisdiction where the character of the properties owned or held under lease by it or the nature of the business transacted by it makes such qualification necessary and where failure to so qualify would have a material adverse effect on the business, operations or financial condition of any of the Borrowers.

4. To my knowledge after due inquiry, there are no legal or arbitral proceedings or any proceedings by or before any governmental or regulatory authority or agency, now pending or threatened against or affecting any of the Borrowers or the rights of any of the Borrowers which could reasonably be expected to have a material adverse effect on the financial condition, operations or business of any of the Borrowers or the ability of any of the Borrowers to perform its respective obligations under the Credit Documents.

5. None of (a) the execution and delivery of the Credit Documents, (b) the consummation of the transactions therein contemplated, or (c) compliance with the terms and provisions thereof will (i) violate or result in a breach of, or require any consent under, the certificate or articles, as the case may be, of incorporation or organization or bylaws or other constitutional document of any of the Borrowers, or any law or regulation applicable to any of the Borrowers, or any of their respective properties, or any order, writ, injunction or decree of any court or Governmental Authority or agency known to us after due inquiry, (ii) violate or result in a breach of or a default under any material agreement, document or instrument to which any of the Borrowers is a party or by which any of the Borrowers or their respective properties are bound, known to me after due inquiry (a "Material Contract"), or (iii) except for the Liens permitted by the Agreement, result in the creation or imposition of any Lien upon any of the revenues or assets of any of the Borrowers pursuant to the terms of any such Material Contract.

6. Each of the Borrowers has all necessary power and authority to execute, deliver and perform its respective obligations under the Credit Documents to which it is a party, and the execution, delivery and performance by each of the Borrowers of the Credit Documents to which it is a party and the obligations thereunder have been duly authorized by all necessary action.

7. Each of the Credit Documents to which any Loan Party is a party have been duly and validly executed and delivered by such Loan Party and constitutes the legal, valid and binding obligations of such Loan Party enforceable against it in accordance with their respective terms, except that the enforceability thereof may be limited (a) by bankruptcy, insolvency, reorganization, fraudulent conveyance or moratorium or other similar laws relating to the

Exhibit J to Credit Agreement � Page 2

enforcement of creditors' rights generally and (b) by general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law).

8. No authorizations, approvals or consents of, or filings or registrations with, any governmental or regulatory authority or agency are necessary for the execution, delivery or performance by any of the Borrowers of the Credit Documents to which it is a party, except for authorizations, consents and approvals that have already been obtained and filings which have already been made.

9. Neither the Company nor any of its Subsidiaries is engaged principally, or as one of its important activities, in the business of extending credit for the purpose of purchasing or carrying margin stock (within the meaning of Regulation U or X of the Board of Governors of the Federal Reserve System).

10. Neither the Company nor 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.

The opinions expressed herein are as of the date hereof only, and I assume no obligation to update or supplement such opinions to reflect any fact or circumstance that may hereafter come to my attention or any change in law that may occur or become effective.

The foregoing opinion is, with your concurrence, predicated upon and qualified in its entirety by the following:

I am a member of the Bar of the State of Arkansas, and I express no opinion as to the laws of any jurisdiction, other than the Federal Laws of the United States of America, the Laws of the State of Arkansas, the Delaware General Corporation Law, and Delaware limited liability company law. Insofar as the foregoing opinion involves agreements that purport to be governed by Texas or other states' laws, I have assumed that such law is the same as the Law of the State of Arkansas.

This opinion is solely for your benefit and may not be relied upon by any person other than you and your counsel and any of your assignees and participants.

Very truly yours,

Michael R. Johns
