All covenants hereunder shall be given independent effect so that if a particular action or condition is not permitted by any of such covenants, the fact that it would be permitted by an exception to, or otherwise within the limitations of, another covenant shall not avoid the occurrence of a default if such action is taken or condition exists. In addition, all representations and warranties hereunder shall be given independent effect so that if a particular representation or warranty proves to be incorrect or is breached, the fact that another representation or warranty concerning the same or similar subject matter is correct or is not breached will not affect the incorrectness of a breach of a representation or warranty hereunder.

II ADVANCES, PAYMENTS.

     2.1. Revolving Advances.

          (a) Amount of Revolving Advances. Subject to the terms and conditions set forth in this Agreement including Sections 2.1(b), each Lender, severally and not jointly, will make Revolving Advances to Borrowers in aggregate amounts outstanding at any time equal to such Lender’s Commitment Percentage of the lesser of (x) the Maximum Revolving Advance Amount less the aggregate Maximum Undrawn Amount of all outstanding Letters of Credit, or (y) the Note Indebtedness Limitation, or (z) an amount equal to the sum of:

     (i) up to 85%, subject to the provisions of Section 2.1(b) hereof, of Eligible Domestic Receivables (the “Domestic Advance Rate”), plus

     (ii) up to the lesser of (A) 85%, subject to the provisions of Section 2.1(b) hereof, of Eligible Foreign Receivables or (B) $10,000,000 (the “Foreign Advance Rate” and together with the Domestic Advance Rate, the “Advance Rate”), minus

     (iii) the aggregate Maximum Undrawn Amount of all outstanding Letters of Credit, minus

     (iv) such reserves as Agent may reasonably deem proper and necessary from time to time, including, but not limited to, the Permanent Reserves.

     The amount derived from the sum of (x) Sections 2.1(a)(z)(i) and (ii) minus (y) Section 2.1(a)(z)(iv) at any time and from time to time shall be referred to as the “Formula Amount”. The Revolving Advances shall be evidenced by one or more secured promissory notes (collectively, the “Revolving Credit Note”) substantially in the form attached hereto as Exhibit 2.1(a).

          (b) Discretionary Rights. The Advance Rates may be increased or decreased by Agent at any time and from time to time in the exercise of its reasonable discretion. Each Borrower consents to any such increases or decreases and acknowledges that decreasing the Advance Rates or increasing or imposing reserves may limit or restrict Advances requested by Borrowing Agent. The rights of Agent under this subsection are subject to the provisions of Section 16.2(b).

     2.2. Procedure for Revolving Advances Borrowing.

          (a) Borrowing Agent on behalf of any Borrower may notify Agent prior to 10:00 a.m. (Dallas, Texas time) on a Business Day of a Borrower’s request to incur, on that day, a Revolving Advance hereunder. Subject to the satisfaction of the conditions set forth in Section 8.3 hereof, in the event any Borrower desires a CapEx Loan, Borrowing Agent shall give Agent at least three (3) Business Days’ prior written notice. Should any amount required to be paid as interest hereunder, or as fees or other charges under this Agreement or any other agreement with Agent or Lenders, or with respect to any other Obligation, become due, same shall be deemed a request for a Revolving Advance as of the date such payment is due, in the amount required to pay in full such interest, fee, charge or Obligation under this Agreement or any other agreement with Agent or Lenders, and such request shall be irrevocable.

          (b) Notwithstanding the provisions of subsection (a) above, in the event any Borrower desires to obtain a Eurodollar Rate Loan, Borrowing Agent shall give Agent written notice by no later than 10:00 a.m. (Dallas, Texas time) on the day which is three (3) Business Days prior to the date such Eurodollar Rate Loan is to be borrowed, specifying (i) the date of the proposed borrowing (which shall be a Business Day), (ii) the type of borrowing and the amount on the date of such Advance to be borrowed, which amount shall be for at least $500,000 and if greater, in an integral multiple of $100,000 and (iii) the duration of the first Interest Period therefor. Interest Periods for Eurodollar Rate Loans shall be for one, two, three or six months; provided, if an Interest Period would end on a day that is not a Business Day, it shall end on the next succeeding Business Day unless such day falls in the next succeeding calendar month in which case the Interest Period shall end on the next preceding Business Day. No Eurodollar Rate Loan shall be made available to any Borrower during the continuance of a Default or an Event of Default. After giving effect to each requested Eurodollar Rate Loan, including those which are converted from a Domestic Rate Loan under Section 2.2(d), there shall not be outstanding more than five (5) Eurodollar Rate Loans, in the aggregate.

          (c) Each Interest Period of a Eurodollar Rate Loan shall commence on the date such Eurodollar Rate Loan is made and shall end on such date as Borrowing Agent may elect as set forth in subsection (b)(iii) above provided that the exact length of each Interest Period shall be determined in accordance with the practice of the interbank market for offshore Dollar deposits and no Interest Period shall end after the last day of the Term.

     Borrowing Agent shall elect the initial Interest Period applicable to a Eurodollar Rate Loan by its notice of borrowing given to Agent pursuant to Section 2.2(b) or by its notice of conversion given to Agent pursuant to Section 2.2(d), as the case may be. Borrowing Agent shall elect the duration of each succeeding Interest Period by giving irrevocable written notice to Agent of such duration not later than 10:00 a.m. (Dallas, Texas time) on the day which is three

Amended & Restated Credit Agreement

(3) Business Days prior to the last day of the then current Interest Period applicable to such Eurodollar Rate Loan. If Agent does not receive timely notice of the Interest Period elected by Borrowing Agent, Borrowing Agent shall be deemed to have elected to convert to a Domestic Rate Loan subject to Section 2.2(d) hereinbelow.

          (d) Provided that no Event of Default shall have occurred and be continuing, Borrowing Agent may, on the last Business Day of the then current Interest Period applicable to any outstanding Eurodollar Rate Loan, or on any Business Day with respect to Domestic Rate Loans, convert any such loan into a loan of another type in the same aggregate principal amount provided that any conversion of a Eurodollar Rate Loan shall be made only on the last Business Day of the then current Interest Period applicable to such Eurodollar Rate Loan. If Borrowing Agent desires to convert a loan, Borrowing Agent shall give Agent written notice by no later than 10:00 a.m. (Dallas, Texas time) (i) on the day which is three (3) Business Days’ prior to the date on which such conversion is to occur with respect to a conversion from a Domestic Rate Loan to a Eurodollar Rate Loan, or (ii) on the day which is one (1) Business Day prior to the date on which such conversion is to occur with respect to a conversion from a Eurodollar Rate Loan to a Domestic Rate Loan, specifying, in each case, the date of such conversion, the loans to be converted and if the conversion is from a Domestic Rate Loan to any other type of loan, the duration of the first Interest Period therefor.

          (e) At its option and upon written notice given prior to 10:00 a.m. (Dallas, Texas time) at least three (3) Business Days’ prior to the date of such prepayment, any Borrower may prepay the Eurodollar Rate Loans in whole at any time or in part from time to time, with accrued interest on the principal being prepaid to the date of such repayment. Such Borrower shall specify the date of prepayment of Advances which are Eurodollar Rate Loans and the amount of such prepayment. In the event that any prepayment of a Eurodollar Rate Loan is required or permitted on a date other than the last Business Day of the then current Interest Period with respect thereto, such Borrower shall indemnify Agent and Lenders therefor in accordance with Section 2.2(f) hereof.

          (f) Each Borrower shall indemnify Agent and Lenders and hold Agent and Lenders harmless from and against any and all losses or expenses that Agent and Lenders may sustain or incur as a consequence of any prepayment, conversion of or any default by any Borrower in the payment of the principal of or interest on any Eurodollar Rate Loan or failure by any Borrower to complete a borrowing of, a prepayment of or conversion of or to a Eurodollar Rate Loan after notice thereof has been given, including, but not limited to, any interest payable by Agent or Lenders to lenders of funds obtained by it in order to make or maintain its Eurodollar Rate Loans hereunder. A certificate as to any additional amounts payable pursuant to the foregoing sentence submitted by Agent or any Lender to Borrowing Agent shall be conclusive absent manifest error.

          (g) Notwithstanding any other provision hereof, if any Applicable Law, treaty, regulation or directive, or any change therein or in the interpretation or application thereof, shall make it unlawful for any Lender (for purposes of this subsection (g), the term “Lender” shall include any Lender and the office or branch where any Lender or any corporation or bank controlling such Lender makes or maintains any Eurodollar Rate Loans) to make or maintain its Eurodollar Rate Loans, the obligation of Lenders to make Eurodollar Rate Loans hereunder shall

Amended & Restated Credit Agreement

forthwith be cancelled and Borrowers shall, if any affected Eurodollar Rate Loans are then outstanding, promptly upon request from Agent, either pay all such affected Eurodollar Rate Loans or convert such affected Eurodollar Rate Loans into loans of another type. If any such payment or conversion of any Eurodollar Rate Loan is made on a day that is not the last day of the Interest Period applicable to such Eurodollar Rate Loan, Borrowers shall pay Agent, upon Agent’s request, such amount or amounts as may be necessary to compensate Lenders for any loss or expense sustained or incurred by Lenders in respect of such Eurodollar Rate Loan as a result of such payment or conversion, including (but not limited to) any interest or other amounts payable by Lenders to lenders of funds obtained by Lenders in order to make or maintain such Eurodollar Rate Loan. A certificate as to any additional amounts payable pursuant to the foregoing sentence submitted by Lenders to Borrowing Agent shall be conclusive absent manifest error.

     2.3. Disbursement of Advance Proceeds.

     All Advances shall be disbursed from whichever office or other place Agent may designate from time to time and, together with any and all other Obligations of Borrowers to Agent or Lenders, shall be charged to Borrowers’ Account on Agent’s books. During the Term, Borrowers may use the Revolving Advances by borrowing, prepaying and reborrowing, all in accordance with the terms and conditions hereof. The proceeds of each Revolving Advance requested by Borrowing Agent on behalf of any Borrower or deemed to have been requested by any Borrower under Section 2.2 hereof shall, with respect to requested Revolving Advances to the extent Lenders make such Revolving Advances, be made available to the applicable Borrower on the day so requested by way of credit to such Borrower’s operating account at PNC, or such other bank located in the United States as Borrowing Agent may designate following notification to Agent, in immediately available federal funds or other immediately available funds or, with respect to Revolving Advances deemed to have been requested by any Borrower, be disbursed to Agent to be applied to the outstanding Obligations giving rise to such deemed request.

     2.4. Loans.

          (a) CapEx Loans.

     (i) Subject to the terms and conditions of this Agreement, each Lender, severally and not jointly, shall, from time to time, make available Advances to one or more Borrowers (each, a “CapEx Loan” and collectively, the “CapEx Loans”) to finance each applicable Borrower’s purchase of Equipment for use in each such Borrower’s business. All such CapEx Loans shall be in such amounts as are requested by Borrowing Agent, but in no event shall any CapEx Loan exceed ninety (90%) percent of the net invoice cost (excluding taxes, shipping, delivery, handling, installation, overhead and other so called “soft” costs) of the Equipment then to be purchased by Borrowers and the total amount of all CapEx Loans outstanding hereunder shall not exceed, in the aggregate, the sum of Six Million Five Hundred Thousand Dollars ($6,500,000.00). Once repaid CapEx Loans may not be reborrowed.

     (ii) Advances constituting CapEx Loans shall be accumulated during each six month period (each a “Borrowing Period”) during the Term. Notwithstanding the

Amended & Restated Credit Agreement

foregoing, the first Borrowing Period shall commence on the Restated Closing Date and end on December 31, 2007 (the “Initial Borrowing Period”). Each subsequent Borrowing Period shall consist of six month periods commencing on January 1, 2008. For the twelve-month period commencing on the Restated Closing Date and ending on December 31, 2007, only interest will be due and payable on the CapEx Loans. Thereafter, at the end of each Borrowing Period, the sum of all CapEx Loans made during the Borrowing Period shall amortize on the basis of a forty-eight (48) month schedule (such amount as determined with respect to any Borrowing Period, the “Amortization Amount”). Monthly principal payments will be initially determined for the CapEx Loans made during the Initial Borrowing Period and the amount of such monthly principal payments shall be increased upon the completion of each such subsequent Borrowing Period by the Amortization Amount for each such subsequent Borrowing Period. The CapEx Loans shall be, with respect to principal, payable in equal monthly installments based upon the amortization schedule set forth above, commencing on January 1, 2008 and on the first day of each month thereafter with the balance payable upon the expiration of the Term, subject to acceleration upon the occurrence of an Event of Default under this Agreement or termination of this Agreement. CapEx Loans shall be evidenced by one or more secured promissory notes (collectively, the “CapEx Note”) in substantially the form attached hereto as Exhibit 2.4(a).

     (iii) Voluntary prepayments of the CapEx Loans shall be applied in the inverse order of scheduled payments and may not be reborrowed.

     2.5. Maximum Advances. The aggregate balance of Revolving Advances outstanding at any time shall not exceed the lesser of (a) the Maximum Revolving Advance Amount or (b) the Formula Amount, less, in each case, the aggregate Maximum Undrawn Amount of all issued and outstanding Letters of Credit.

     2.6. Repayment of Advances.

          (a) The Advances shall be due and payable in full on the last day of the Term subject to earlier prepayment as herein provided. The CapEx Loans shall be due and payable as provided in Section 2.4(a) hereof and in the CapEx Note, subject to mandatory prepayments as herein provided.

          (b) Each Borrower recognizes that the amounts evidenced by checks, notes, drafts or any other items of payment relating to and/or proceeds of Collateral may not be collectible by Agent on the date received. In consideration of Agent’s agreement to conditionally credit Borrowers’ Account as of the Business Day on which Agent receives those items of payment, each Borrower agrees that, in computing the charges under this Agreement, all items of payment shall be deemed applied by Agent on account of the Obligations one (1) Business Day after (i) the Business Day Agent receives such payments via wire transfer or electronic depository check or (ii) in the case of payments received by Agent in any other form, the Business Day such payment constitutes good funds in Agent’s account. Agent is not, however, required to credit Borrowers’ Account for the amount of any item of payment which is unsatisfactory to Agent and Agent may charge Borrowers’ Account for the amount of any item of payment which is returned to Agent unpaid.

Amended & Restated Credit Agreement

          (c) All payments of principal, interest and other amounts payable hereunder, or under any of the Other Documents shall be made to Agent at the Payment Office not later than 1:00 p.m. (Dallas, Texas time) on the due date therefor in lawful money of the United States of America in federal funds or other funds immediately available to Agent. Agent shall have the right to effectuate payment on any and all Obligations due and owing hereunder by charging Borrowers’ Account or by making Advances as provided in Section 2.2 hereof.

          (d) Borrowers shall pay principal, interest, and all other amounts payable hereunder, or under any related agreement, without any deduction whatsoever, including, but not limited to, any deduction for any setoff or counterclaim.

     2.7. Repayment of Excess Advances. The aggregate balance of Advances outstanding at any time in excess of the maximum amount of Advances permitted hereunder shall be immediately due and payable without the necessity of any demand, at the Payment Office, whether or not a Default or Event of Default has occurred.

     2.8. Statement of Account. Agent shall maintain, in accordance with its customary procedures, a loan account (“Borrowers’ Account”) in the name of Borrowers in which shall be recorded the date and amount of each Advance made by Agent and the date and amount of each payment in respect thereof; provided, however, the failure by Agent to record the date and amount of any Advance shall not adversely affect Agent or any Lender. Each month, Agent shall send to Borrowing Agent a statement showing the accounting for the Advances made, payments made or credited in respect thereof, and other transactions between Agent and Borrowers during such month. The monthly statements shall be deemed correct and binding upon Borrowers in the absence of manifest error and shall constitute an account stated between Lenders and Borrowers unless Agent receives a written statement of Borrowers’ specific exceptions thereto within thirty (30) days after such statement is received by Borrowing Agent. The records of Agent with respect to the loan account shall be conclusive evidence absent manifest error of the amounts of Advances and other charges thereto and of payments applicable thereto.

     2.9. Letters of Credit. Subject to the terms and conditions hereof, Agent shall issue or cause the issuance of standby Letters of Credit (“Letters of Credit”) for the account of any Borrower; provided, however, that Agent will not be required to issue or cause to be issued any Letters of Credit to the extent that the issuance thereof would then cause the sum of (i) the outstanding Revolving Advances plus (ii) the Maximum Undrawn Amount of all outstanding Letters of Credit to exceed the lesser of (x) the Maximum Revolving Advance Amount or (y) the Formula Amount. The Maximum Undrawn Amount of outstanding Letters of Credit shall not exceed in the aggregate at any time the Letter of Credit Sublimit. All disbursements or payments related to Letters of Credit shall be deemed to be Revolving Advances and shall bear interest at the Revolving Interest Rate; Letters of Credit that have not been drawn upon shall not bear interest.

     2.10. Issuance of Letters of Credit.

          (a) Borrowing Agent, on behalf of Borrowers, may request Agent to issue or cause the issuance of a Letter of Credit by delivering to Agent at the Payment Office, prior to

Amended & Restated Credit Agreement

10:00 a.m. (Dallas, Texas time), at least five (5) Business Days’ prior to the proposed date of issuance, Agent’s form of Letter of Credit Application (the “Letter of Credit Application”) completed to the satisfaction of Agent; and, such other certificates, documents and other papers and information as Agent may reasonably request. Borrowing Agent, on behalf of Borrowers, also has the right to give instructions and make agreements with respect to any application, any applicable letter of credit and security agreement, any applicable letter of credit reimbursement agreement and/or any other applicable agreement, any letter of credit and the disposition of documents, disposition of any unutilized funds, and to agree with Agent upon any amendment, extension or renewal of any Letter of Credit.

          (b) Each Letter of Credit shall, among other things, (i) provide for the payment of sight drafts, other written demands for payment, or acceptances of usance drafts when presented for honor thereunder in accordance with the terms thereof and when accompanied by the documents described therein and (ii) have an expiry date not later than twelve (12) months after such Letter of Credit’s date of issuance and in no event later than the last day of the Term. Each standby Letter of Credit shall be subject either to the Uniform Customs and Practice for Documentary Credits (1993 Revision), International Chamber of Commerce Publication No. 500, and any amendments or revision thereof adhered to by the Issuer (“UCP 500”) or the International Standby Practices (ISP98-International Chamber of Commerce Publication Number 590) (the “ISP98 Rules”), as determined by Agent, and each trade Letter of Credit shall be subject to UCP 500.

          (c) Agent shall use its reasonable efforts to notify Lenders of the request by Borrowing Agent for a Letter of Credit hereunder.

     2.11. Requirements For Issuance of Letters of Credit.

          (a) Borrowing Agent shall authorize and direct any Issuer to name the applicable Borrower as the “Applicant” or “Account Party” of each Letter of Credit. If Agent is not the Issuer of any Letter of Credit, Borrowing Agent shall authorize and direct the Issuer to deliver to Agent all instruments, documents, and other writings and property received by the Issuer pursuant to the Letter of Credit and to accept and rely upon Agent’s instructions and agreements with respect to all matters arising in connection with the Letter of Credit, the application therefor or any acceptance therefor.

          (b) In connection with all Letters of Credit issued or caused to be issued by Agent under this Agreement, each Borrower hereby appoints Agent, or its designee, as its attorney, with full power and authority if an Event of Default shall have occurred, (i) to sign and/or endorse such Borrower’s name upon any warehouse or other receipts, letter of credit applications and acceptances, (ii) to sign such Borrower’s name on bills of lading; (iii) to clear Inventory through the United States of America Customs Department (“Customs”) in the name of such Borrower or Agent or Agent’s designee, and to sign and deliver to Customs officials powers of attorney in the name of Borrower for such purpose; and (iv) to complete in such Borrower’s name or Agent’s, or in the name of Agent’s designee, any order, sale or transaction, obtain the necessary documents in connection therewith, and collect the proceeds thereof. Neither Agent nor its attorneys will be liable for any acts or omissions nor for any error of judgment or mistakes of fact or law, except for Agent’s or its attorney’s willful misconduct. This

Amended & Restated Credit Agreement

power, being coupled with an interest, is irrevocable as long as any Letters of Credit remain outstanding.

     2.12. Disbursements, Reimbursement.

          (a) Immediately upon the issuance of each Letter of Credit, each Lender shall be deemed to, and hereby irrevocably and unconditionally agrees to, purchase from Agent a participation in such Letter of Credit and each drawing thereunder in an amount equal to such Lender’s Commitment Percentage of the Maximum Face Amount of such Letter of Credit and the amount of such drawing, respectively.

          (b) In the event of any request for a drawing under a Letter of Credit by the beneficiary or transferee thereof, Agent will promptly notify Borrowing Agent. Provided that Borrowing Agent shall have received such notice, the Borrowers shall reimburse (such obligation to reimburse Agent shall sometimes be referred to as a “Reimbursement Obligation”) Agent prior to 12:00 p.m., Dallas, Texas time on each date that an amount is paid by Agent under any Letter of Credit (each such date, a “Drawing Date”) in an amount equal to the amount so paid by Agent. In the event Borrowers fail to reimburse Agent for the full amount of any drawing under any Letter of Credit by 12:00 p.m., Dallas, Texas time, on the Drawing Date, Agent will promptly notify each Lender thereof, and Borrowers shall be deemed to have requested that a Domestic Rate Loan be made by the Lenders to be disbursed on the Drawing Date under such Letter of Credit, subject to the amount of the unutilized portion of the lesser of Maximum Revolving Advance Amount or the Formula Amount and subject to Section 8.2 hereof. Any notice given by Agent pursuant to this Section 2.12(b) may be oral if immediately confirmed in writing; provided that the lack of such an immediate confirmation shall not affect the conclusiveness or binding effect of such notice.

          (c) Each Lender shall upon any notice pursuant to Section 2.12(b) make available to Agent an amount in immediately available funds equal to its Commitment Percentage of the amount of the drawing, whereupon the participating Lenders shall (subject to Section 2.12(d)) each be deemed to have made a Domestic Rate Loan to Borrowers in that amount. If any Lender so notified fails to make available to Agent the amount of such Lender’s Commitment Percentage of such amount by no later than 2:00 p.m., Dallas, Texas time on the Drawing Date, then interest shall accrue on such Lender’s obligation to make such payment, from the Drawing Date to the date on which such Lender makes such payment (i) at a rate per annum equal to the Federal Funds Rate during the first three days following the Drawing Date and (ii) at a rate per annum equal to the rate applicable to Domestic Rate Loans on and after the fourth day following the Drawing Date. Agent will promptly give notice of the occurrence of the Drawing Date, but failure of Agent to give any such notice on the Drawing Date or in sufficient time to enable any Lender to effect such payment on such date shall not relieve such Lender from its obligation under this Section 2.12(c), provided that such Lender shall not be obligated to pay interest as provided in Section 2.12(c) (i) and (ii) until and commencing from the date of receipt of notice from Agent of a drawing.

          (d) With respect to any unreimbursed drawing that is not converted into a Domestic Rate Loan to Borrowers in whole or in part as contemplated by Section 2.12(b), because of Borrowers’ failure to satisfy the conditions set forth in Section 8.2 (other than any

Amended & Restated Credit Agreement

notice requirements) or for any other reason, Borrowers shall be deemed to have incurred from Agent a borrowing (each a “Letter of Credit Borrowing”) in the amount of such drawing. Such Letter of Credit Borrowing shall be due and payable on demand (together with interest) and shall bear interest at the rate per annum applicable to a Domestic Rate Loan. Each Lender’s payment to Agent pursuant to Section 2.12(c) shall be deemed to be a payment in respect of its participation in such Letter of Credit Borrowing and shall constitute a “Participation Advance” from such Lender in satisfaction of its Participation Commitment under this Section 2.12.

          (e) Each Lender’s Participation Commitment shall continue until the last to occur of any of the following events: (x) Agent ceases to be obligated to issue or cause to be issued Letters of Credit hereunder; (y) no Letter of Credit issued or created hereunder remains outstanding and uncancelled and (z) all Persons (other than the Borrowers) have been fully reimbursed for all payments made under or relating to Letters of Credit.

     2.13. Repayment of Participation Advances.

          (a) Upon (and only upon) receipt by Agent for its account of immediately available funds from Borrowers (i) in reimbursement of any payment made by the Agent under the Letter of Credit with respect to which any Lender has made a Participation Advance to Agent, or (ii) in payment of interest on such a payment made by Agent under such a Letter of Credit, Agent will pay to each Lender, in the same funds as those received by Agent, the amount of such Lender’s Commitment Percentage of such funds, except Agent shall retain the amount of the Commitment Percentage of such funds of any Lender that did not make a Participation Advance in respect of such payment by Agent.

          (b) If Agent is required at any time to return to any Borrower, or to a trustee, receiver, liquidator, custodian, or any official in any insolvency proceeding, any portion of the payments made by Borrowers to Agent pursuant to Section 2.13(a) in reimbursement of a payment made under the Letter of Credit or interest or fee thereon, each Lender shall, on demand of Agent, forthwith return to Agent the amount of its Commitment Percentage of any amounts so returned by Agent plus interest at the Federal Funds Effective Rate.

     2.14. Documentation. Each Borrower agrees to be bound by the terms of the Letter of Credit Application and by Agent’s interpretations of any Letter of Credit issued on behalf of such Borrower and by Agent’s written regulations and customary practices relating to letters of credit, though Agent’s interpretations may be different from such Borrower’s own. In the event of a conflict between the Letter of Credit Application and this Agreement, this Agreement shall govern and control. It is understood and agreed that, except in the case of gross negligence or willful misconduct (as determined by a court of competent jurisdiction in a final non-appealable judgment), Agent shall not be liable for any error, negligence and/or mistakes, whether of omission or commission (INCLUDING WITHOUT LIMITATION, WITH RESPECT TO ANY ACT OR INACTION ARISING FROM AGENT’S NEGLIGENCE OR STRICT LIABILITY), in following the Borrowing Agent’s or any Borrower’s instructions or those contained in the Letters of Credit or any modifications, amendments or supplements thereto.

     2.15. Determination to Honor Drawing Request. In determining whether to honor any request for drawing under any Letter of Credit by the beneficiary thereof, Agent shall be

Amended & Restated Credit Agreement

responsible only to determine that the documents and certificates required to be delivered under such Letter of Credit have been delivered and that they comply on their face with the requirements of such Letter of Credit and that any other drawing condition appearing on the face of such Letter of Credit has been satisfied in the manner so set forth.

     2.16. Nature of Participation and Reimbursement Obligations. Each Lender’s obligation in accordance with this Agreement to make the Revolving Advances or Participation Advances as a result of a drawing under a Letter of Credit, and the obligations of Borrowers to reimburse Agent upon a draw under a Letter of Credit, shall be absolute, unconditional and irrevocable, and shall be performed strictly in accordance with the terms of this Section 2.16 under all circumstances, including the following circumstances:

               (i) any set-off, counterclaim, recoupment, defense or other right which such Lender may have against Agent, any Borrower or any other Person for any reason whatsoever;

               (ii) the failure of any Borrower or any other Person to comply, in connection with a Letter of Credit Borrowing, with the conditions set forth in this Agreement for the making of a Revolving Advance, it being acknowledged that such conditions are not required for the making of a Letter of Credit Borrowing and the obligation of the Lenders to make Participation Advances under Section 2.12;

               (iii) any lack of validity or enforceability of any Letter of Credit;

               (iv) any claim of breach of warranty that might be made by Borrower or any Lender against the beneficiary of a Letter of Credit, or the existence of any claim, set-off, recoupment, counterclaim, crossclaim, defense or other right which any Borrower or any Lender may have at any time against a beneficiary, any successor beneficiary or any transferee of any Letter of Credit or the proceeds thereof (or any Persons for whom any such transferee may be acting), Agent or any Lender or any other Person, whether in connection with this Agreement, the transactions contemplated herein or any unrelated transaction (including any underlying transaction between any Borrower or any Subsidiaries of such Borrower and the beneficiary for which any Letter of Credit was procured);

               (v) the lack of power or authority of any signer of (or any defect in or forgery of any signature or endorsement on) or the form of or lack of validity, sufficiency, accuracy, enforceability or genuineness of any draft, demand, instrument, certificate or other document presented under or in connection with any Letter of Credit, or any fraud or alleged fraud in connection with any Letter of Credit, or the transport of any property or provisions of services relating to a Letter of Credit, in each case even if Agent or any of Agent’s Affiliates has been notified thereof;

               (vi) payment by Agent under any Letter of Credit against presentation of a demand, draft or certificate or other document which does not comply with the terms of such Letter of Credit;

               (vii) the solvency of, or any acts or omissions by, any beneficiary of any Letter of Credit, or any other Person having a role in any transaction or obligation relating to a

Amended & Restated Credit Agreement

Letter of Credit, or the existence, nature, quality, quantity, condition, value or other characteristic of any property or services relating to a Letter of Credit;

               (viii) any failure by the Agent or any of Agent’s Affiliates to issue any Letter of Credit in the form requested by Borrowing Agent, unless the Agent has received written notice from Borrowing Agent of such failure within three (3) Business Days after the Agent shall have furnished Borrowing Agent a copy of such Letter of Credit and such error is material and no drawing has been made thereon prior to receipt of such notice;

               (ix) any Material Adverse Effect on any Borrower or any Guarantor;

               (x) any breach of this Agreement or any Other Document by any party thereto;

               (xi) the occurrence or continuance of an insolvency proceeding with respect to any Borrower or any Guarantor;

               (xii) the fact that a Default or Event of Default shall have occurred and be continuing;

               (xiii) the fact that the Term shall have expired or this Agreement or the Obligations hereunder shall have been terminated; and

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

     2.17. Indemnity. In addition to amounts payable as provided in Section 16.5, each Borrower hereby agrees to protect, indemnify, defend, pay and save harmless Agent and any of Agent’s Affiliates that have issued a Letter of Credit from and against any and all claims, demands, liabilities, damages, taxes, penalties, interest, judgments, settlements, losses, costs, charges and expenses (including reasonable fees, expenses and disbursements of counsel and allocated costs of internal counsel) which the Agent or any of Agent’s Affiliates may incur or be subject to as a consequence, direct or indirect, of the issuance of any Letter of Credit, other than as a result of (A) the gross negligence or willful misconduct of the Agent as determined by a final and non-appealable judgment of a court of competent jurisdiction or (B) the wrongful dishonor by the Agent or any of Agent’s Affiliates of a proper demand for payment made under any Letter of Credit (INCLUDING, WITHOUT LIMITATION, WITH RESPECT TO ANY OTHERWISE INDEMNIFIED MATTER ARISING FROM AGENT’S NEGLIGENCE OR STRICT LIABILITY), except if such dishonor resulted from any act or omission, whether rightful or wrongful, of any present or future de jure or de facto Governmental Body (all such acts or omissions herein called “Governmental Acts”).

     2.18. Liability for Acts and Omissions. As between Borrowers and Agent and Lenders, each Borrower assumes all risks of the acts and omissions of, or misuse of the Letters of Credit by, the respective beneficiaries of such Letters of Credit (INCLUDING, WITHOUT LIMITATION, ALL RISKS ATTRIBUTABLE TO ANY ACT OR OMISSION ARISING FROM AGENT’S OR LENDER’S NEGLIGENCE OR STRICT LIABILITY). In furtherance and not in limitation of the respective foregoing, Agent shall not be responsible for:

Amended & Restated Credit Agreement

(i) the form, validity, sufficiency, accuracy, genuineness or legal effect of any document submitted by any party in connection with the application for an issuance of any such Letter of Credit, even if it should in fact prove to be in any or all respects invalid, insufficient, inaccurate, fraudulent or forged (even if Agent shall have been notified thereof); (ii) the validity or sufficiency of any instrument transferring or assigning or purporting to transfer or assign any such Letter of Credit or the rights or benefits thereunder or proceeds thereof, in whole or in part, which may prove to be invalid or ineffective for any reason; (iii) the failure of the beneficiary of any such Letter of Credit, or any other party to which such Letter of Credit may be transferred, to comply fully with any conditions required in order to draw upon such Letter of Credit or any other claim of any Borrower against any beneficiary of such Letter of Credit, or any such transferee, or any dispute between or among any Borrower and any beneficiary of any Letter of Credit or any such transferee; (iv) errors, omissions, interruptions or delays in transmission or delivery of any messages, by mail, cable, telegraph, telex or otherwise, whether or not they be in cipher; (v) errors in interpretation of technical terms; (vi) any loss or delay in the transmission or otherwise of any document required in order to make a drawing under any such Letter of Credit or of the proceeds thereof; (vii) the misapplication by the beneficiary of any such Letter of Credit of the proceeds of any drawing under such Letter of Credit; or (viii) any consequences arising from causes beyond the control of Agent, including any governmental acts, and none of the above shall affect or impair, or prevent the vesting of, any of Agent’s rights or powers hereunder. Nothing in the preceding sentence shall relieve Agent from liability for Agent’s gross negligence or willful misconduct (as determined by a court of competent jurisdiction in a final non-appealable judgment) in connection with actions or omissions described in such clauses (i) through (viii) of such sentence. In no event shall Agent or Agent’s Affiliates be liable to any Borrower for any indirect, consequential, incidental, punitive, exemplary or special damages or expenses (including without limitation attorneys’ fees), or for any damages resulting from any change in the value of any property relating to a Letter of Credit.

     Without limiting the generality of the foregoing, Agent and each of its Affiliates (i) may rely on any oral or other communication believed in good faith by Agent or such Affiliate to have been authorized or given by or on behalf of the applicant for a Letter of Credit, (ii) may honor any presentation if the documents presented appear on their face substantially to comply with the terms and conditions of the relevant Letter of Credit; (iii) may honor a previously dishonored presentation under a Letter of Credit, whether such dishonor was pursuant to a court order, to settle or compromise any claim of wrongful dishonor, or otherwise, and shall be entitled to reimbursement to the same extent as if such presentation had initially been honored, together with any interest paid by Agent or its Affiliates; (iv) may honor any drawing that is payable upon presentation of a statement advising negotiation or payment, upon receipt of such statement (even if such statement indicates that a draft or other document is being delivered separately), and shall not be liable for any failure of any such draft or other document to arrive, or to conform in any way with the relevant Letter of Credit; (v) may pay any paying or negotiating bank claiming that it rightfully honored under the laws or practices of the place where such bank is located; and (vi) may settle or adjust any claim or demand made on Agent or its Affiliate in any way related to any order issued at the applicant’s request to an air carrier, a letter of guarantee or of indemnity issued to a carrier or any similar document (each an “Order”) and honor any drawing in connection with any Letter of Credit that is the subject of such Order, notwithstanding that any drafts or other documents presented in connection with such Letter of Credit fail to conform in any way with such Letter of Credit.

Amended & Restated Credit Agreement

     In furtherance and extension and not in limitation of the specific provisions set forth above, any action taken or omitted by Agent under or in connection with the Letters of Credit issued by it or any documents and certificates delivered thereunder, if taken or omitted in good faith and without gross negligence (as determined by a court of competent jurisdiction in a final non-appealable judgment), shall not put Agent under any resulting liability to any Borrower or any Lender.

     2.19. Additional Payments. Any sums expended by Agent or any Lender due to any Borrower’s failure to perform or comply with its obligations under this Agreement or any Other Document including any Borrower’s obligations under Sections 4.2, 4.4, 4.12, 4.13, 4.14 and 6.1 hereof, may be charged to Borrowers’ Account as a Revolving Advance and added to the Obligations.

     2.20. Manner of Borrowing and Payment.

          (a) Each borrowing of Revolving Advances shall be advanced according to the applicable Commitment Percentages of Lenders. Each borrowing of CapEx Loans shall be advanced according to the applicable Commitment Percentages of Lenders.

          (b) Each payment (including each prepayment) by any Borrower on account of the principal of and interest on the Revolving Advances, shall be applied to the Revolving Advances pro rata according to the applicable Commitment Percentages of Lenders. Each payment (including each prepayment) by any Borrower on account of the principal of and interest on the CapEx Note, shall be applied to that portion of the CapEx Loan evidenced by the CapEx Note pro rata according to the Commitment Percentages of Lenders. Except as expressly provided herein, all payments (including prepayments) to be made by any Borrower on account of principal, interest and fees shall be made without set off or counterclaim and shall be made to Agent on behalf of the Lenders to the Payment Office, in each case on or prior to 1:00 p.m., Dallas, Texas time, in Dollars and in immediately available funds.

          (c) (i) Notwithstanding anything to the contrary contained in Sections 2.20(a) and (b) hereof, commencing with the first Business Day following the Restated Closing Date, each borrowing of Revolving Advances shall be advanced by Agent and each payment by any Borrower on account of Revolving Advances shall be applied first to those Revolving Advances advanced by Agent. On or before 1:00 p.m., Dallas, Texas time, on each Settlement Date commencing with the first Settlement Date following the Restated Closing Date, Agent and Lenders shall make certain payments as follows: (I) if the aggregate amount of new Revolving Advances made by Agent during the preceding Week (if any) exceeds the aggregate amount of repayments applied to outstanding Revolving Advances during such preceding Week, then each Lender shall provide Agent with funds in an amount equal to its applicable Commitment Percentage of the difference between (w) such Revolving Advances and (x) such repayments and (II) if the aggregate amount of repayments applied to outstanding Revolving Advances during such Week exceeds the aggregate amount of new Revolving Advances made during such Week, then Agent shall provide each Lender with funds in an amount equal to its applicable Commitment Percentage of the difference between (y) such repayments and (z) such Revolving Advances.

Amended & Restated Credit Agreement

               (ii) Each Lender shall be entitled to earn interest at the applicable Contract Rate on outstanding Advances which it has funded.

               (iii) Promptly following each Settlement Date, Agent shall submit to each Lender a certificate with respect to payments received and Advances made during the Week immediately preceding such Settlement Date. Such certificate of Agent shall be conclusive in the absence of manifest error.

          (d) If any Lender or Participant (a “Benefited Lender”) shall at any time receive any payment of all or part of its Advances, or interest thereon, or receive any Collateral in respect thereof (whether voluntarily or involuntarily or by set-off) in a greater proportion than any such payment to and Collateral received by any other Lender, if any, in respect of such other Lender’s Advances, or interest thereon, and such greater proportionate payment or receipt of Collateral is not expressly permitted hereunder, such Benefited Lender shall purchase for cash from the other Lenders a participation in such portion of each such other Lender’s Advances, or shall provide such other Lender with the benefits of any such Collateral, or the proceeds thereof, as shall be necessary to cause such Benefited Lender to share the excess payment or benefits of such Collateral or proceeds ratably with each of the other Lenders; provided, however, that if all or any portion of such excess payment or benefits is thereafter recovered from such Benefited Lender, such purchase shall be rescinded, and the purchase price and benefits returned, to the extent of such recovery, but without interest. Each Lender so purchasing a portion of another Lender’s Advances may exercise all rights of payment (including rights of set-off) with respect to such portion as fully as if such Lender were the direct holder of such portion.

          (e) Unless Agent shall have been notified by telephone, confirmed in writing, by any Lender that such Lender will not make the amount which would constitute its applicable Commitment Percentage of the Advances available to Agent, Agent may (but shall not be obligated to) assume that such Lender shall make such amount available to Agent on the next Settlement Date and, in reliance upon such assumption, make available to Borrowers a corresponding amount. Agent will promptly notify Borrowing Agent of its receipt of any such notice from a Lender. If such amount is made available to Agent on a date after such next Settlement Date, such Lender shall pay to Agent on demand an amount equal to the product of (i) the daily average Federal Funds Rate (computed on the basis of a year of 360 days) during such period as quoted by Agent, times (ii) such amount, times (iii) the number of days from and including such Settlement Date to the date on which such amount becomes immediately available to Agent. A certificate of Agent submitted to any Lender with respect to any amounts owing under this paragraph (e) shall be conclusive, in the absence of manifest error. If such amount is not in fact made available to Agent by such Lender within three (3) Business Days after such Settlement Date, Agent shall be entitled to recover such an amount, with interest thereon at the rate per annum then applicable to such Revolving Advances hereunder, on demand from Borrowers; provided, however, that Agent’s right to such recovery shall not prejudice or otherwise adversely affect Borrowers’ rights (if any) against such Lender.

     2.21. Mandatory Prepayments.

          (a) Subject to Section 4.3 hereof and excluding the exceptions set forth therein, when Borrower (i) sells or otherwise disposes of any Collateral other than Inventory in

Amended & Restated Credit Agreement

the Ordinary Course of Business, (ii) other than conversion of the Subordinated Debt to Equity Interests, issues or sells any equity securities, capital stock or other ownership interests, or receives any capital contributions (except to the extent the proceeds of such a sale or issuance are applied to the repayment of the Investor Notes), (iii) incurs any Indebtedness (other than as permitted by Section 7.8 hereof), or (iv) receives any proceeds payable in connection with (A) any condemnation proceedings affecting any of the foregoing or any rights thereto or any interest in or to any Collateral or (B) any damage to or taking of any of the foregoing or any rights in any Collateral or any interest therein arising from or otherwise relating to any exercise of the power of eminent domain, or any conveyance in lieu of or under threat of any such taking, then Borrower shall repay the Advances in an amount equal to the net cash proceeds of the foregoing (i.e., gross proceeds less the reasonable costs of such sales, issuances, contributions or other dispositions), such repayments to be made promptly but in no event more than one (1) Business Day following receipt of such net proceeds, and until the date of payment, such proceeds shall be held in trust for Agent. The foregoing shall not be deemed to be implied consent to any such sale or transaction otherwise prohibited by the terms and conditions hereof. Such repayments shall be applied (i) if the Collateral disposed of is Equipment the purchase of which was financed by a CapEx Loan, (x) first, to the outstanding principal installments of the CapEx Loans in the inverse order of the maturities thereof and (y) second, to the remaining Advances in such order as Agent may determine, subject to Borrowers’ ability to reborrow Revolving Advances in accordance with the terms hereof or (ii) if the Collateral disposed of is Equipment other than as set forth in (i) above, (x) first to the outstanding principal installments of the CapEx Loans in the inverse order of the maturities thereof and (y) second, to the remaining Advances in such order as Agent may determine, subject to Borrowers’ ability to reborrow Revolving Advances in accordance with the terms hereof.

     2.22. Reduction of Commitments.

          (a) The Borrowing Agent may from time to time reduce the Revolving Commitments; provided that (i) each reduction of the Revolving Commitments shall be in an amount that is an integral multiple of $1,000,000, and (ii) the Borrowing Agent shall not reduce the Revolving Commitments if, after giving effect to any concurrent prepayment of the Revolving Advances in accordance with this Agreement, the sum of the outstanding Revolving Advances would exceed the lesser of (i) the total Maximum Revolving Advance Amount and (ii) the Formula Amount minus the aggregate Maximum Undrawn Amount of all outstanding Letters of Credit.

          (b) The Borrowing Agent shall notify the Agent of any election to reduce the Revolving Commitments under paragraph (a) of this Section at least five Business Days prior to the effective date of such reduction, specifying such election and the effective date thereof. Promptly following receipt of any notice, the Agent shall advise the Lenders of the contents thereof. Each notice delivered by the Borrowing Agent pursuant to this Section shall be irrevocable. Any reduction of the Revolving Commitments shall be permanent. Each reduction of the Revolving Commitments shall be made ratably among the Lenders in accordance with their respective Commitment Percentage.

Amended & Restated Credit Agreement

     2.23. Use of Proceeds.

          (a) Borrowers shall apply the proceeds of Advances to (i) pay fees and expenses relating to the Transaction and (ii) provide for Borrowers’ working capital needs (including Capital Expenditures permitted hereunder).

          (b) Without limiting the generality of Section 2.23(a) above, neither the Borrowers, Guarantors, nor any other Person which may in the future become party to this Agreement or the Other Documents as a Borrower or Guarantor, intends to use nor shall they use any portion of the proceeds of the Advances, directly or indirectly, for any purpose in violation of the Trading with the Enemy Act.

     2.24. Defaulting Lender.

          (a) Notwithstanding anything to the contrary contained herein, in the event any Lender (x) has refused (which refusal constitutes a breach by such Lender of its obligations under this Agreement) to make available its portion of any Advance or to refund its portion of any excess interest received as provided in Section 3.6 or (y) notifies either Agent or Borrowing Agent that it does not intend to make available its portion of any Advance (if the actual refusal would constitute a breach by such Lender of its obligations under this Agreement) (each, a “Lender Default”), all rights and obligations hereunder of such Lender (a “Defaulting Lender”) as to which a Lender Default is in effect and of the other parties hereto shall be modified to the extent of the express provisions of this Section 2.24 while such Lender Default remains in effect.

          (b) Advances shall be incurred pro rata from Lenders (the “Non-Defaulting Lenders”) which are not Defaulting Lenders based on their respective Commitment Percentages, and no Commitment Percentage of any Lender or any pro rata share of any Advances required to be advanced by any Lender shall be increased as a result of such Lender Default. Amounts received in respect of principal of any type of Advances shall be applied to reduce the applicable Advances of each Lender (other than any Defaulting Lender) pro rata based on the aggregate of the outstanding Advances of that type of all Lenders at the time of such application; provided, that, Agent shall not be obligated to transfer to a Defaulting Lender any payments received by Agent for the Defaulting Lender’s benefit, nor shall a Defaulting Lender be entitled to the sharing of any payments hereunder (including any principal, interest or fees). Amounts payable to a Defaulting Lender shall instead be paid to or retained by Agent. Agent may hold and, in its discretion, re-lend to a Borrower the amount of such payments received or retained by it for the account of such Defaulting Lender.

          (c) A Defaulting Lender shall not be entitled to give instructions to Agent or to approve, disapprove, consent to or vote on any matters relating to this Agreement and the Other Documents. All amendments, waivers and other modifications of this Agreement and the Other Documents may be made without regard to a Defaulting Lender and, for purposes of the definition of “Required Lenders”, a Defaulting Lender shall be deemed not to be a Lender and not to have Advances outstanding.

          (d) Other than as expressly set forth in this Section 2.24, the rights and obligations of a Defaulting Lender (including the obligation to indemnify Agent) and the other

Amended & Restated Credit Agreement

parties hereto shall remain unchanged. Nothing in this Section 2.24 shall be deemed to release any Defaulting Lender from its obligations under this Agreement and the Other Documents, shall alter such obligations, shall operate as a waiver of any default by such Defaulting Lender hereunder, or shall prejudice any rights which any Borrower, Agent or any Lender may have against any Defaulting Lender as a result of any default by such Defaulting Lender hereunder.

          (e) In the event a Defaulting Lender retroactively cures to the satisfaction of Agent the breach which caused a Lender to become a Defaulting Lender, such Defaulting Lender shall no longer be a Defaulting Lender and shall be treated as a Lender under this Agreement.

III INTEREST AND FEES.

     3.1. Interest. Interest on Advances shall be payable in arrears on the first day of each month with respect to Domestic Rate Loans and, with respect to Eurodollar Rate Loans, at the end of each Interest Period. Interest charges shall be computed on the actual principal amount of Advances outstanding during the month at a rate per annum equal to (i) with respect to Revolving Advances, the applicable Revolving Interest Rate and (ii) with respect to the CapEx Loans, the applicable CapEx Loan Rate (as applicable, the “Contract Rate”). Whenever, subsequent to the date of this Agreement, the Alternate Base Rate is increased or decreased, the applicable Contract Rate shall be similarly changed without notice or demand of any kind by an amount equal to the amount of such change in the Alternate Base Rate during the time such change or changes remain in effect. The Eurodollar Rate shall be adjusted with respect to Eurodollar Rate Loans without notice or demand of any kind on the effective date of any change in the Reserve Percentage as of such effective date. Upon and after the occurrence of an Event of Default, and during the continuation thereof, at the option of Agent or at the direction of Required Lenders, the Obligations shall bear interest at the Contract Rate plus two percent (2%) per annum (as applicable, the “Default Rate”).

     Commencing on the Initial Adjustment Date, the Applicable Margin with respect to the Revolving Advances and the CapEx Loans will be adjusted (up or down) prospectively as determined in accordance with the foregoing table based on the Borrowers’ most recent Financials. For purposes of this Section 3.1, “Financials” shall mean the annual or quarterly financial statements of the Borrowers delivered pursuant to Section 9.7 and Section 9.8 of this Agreement. Adjustments, if any, to the Applicable Margin shall be effective on the first day of the calendar month after the Agent has received the applicable Financials. If the Borrowers fail to deliver the Financials to the Agent at the time required pursuant to this Agreement, then the Applicable Margin shall be the highest Applicable Margin set forth in the foregoing table until five days after such Financials are so delivered. During the period from the Restated Closing Date through the Initial Adjustment Date, the Applicable Margin shall be determined in accordance with the foregoing table as if the Fixed Charge Coverage Ratio were greater than or equal to 1.50 to 1.00 but less than 2.00 to 1.00.

     3.2. Letter of Credit Fees.

          (a) Borrowers shall pay (x) to Agent, for the ratable benefit of Lenders, fees for each Letter of Credit for the period from and excluding the date of issuance of same to and including the date of expiration or termination, equal to the average daily face amount of each outstanding Letter of Credit multiplied by the Applicable Revolving Eurodollar Rate Margin, such fees to be calculated on the basis of a 360-day year for the actual number of days elapsed and to be payable quarterly in arrears on the first day of each quarter and on the last day of the Term, and (y) to the Issuer, a fronting fee of one quarter of one percent (0.25%) per annum, together with any and all administrative, issuance, amendment, payment and negotiation charges with respect to Letters of Credit and all fees and expenses as agreed upon by the Issuer and the Borrowing Agent in connection with any Letter of Credit, including in connection with the opening, amendment or renewal of any such Letter of Credit and any acceptances created thereunder and shall reimburse Agent for any and all fees and expenses, if any, paid by Agent to the Issuer (all of the foregoing fees, the “Letter of Credit Fees”). All such charges shall be deemed earned in full on the date when the same are due and payable hereunder and shall not be subject to rebate or pro-ration upon the termination of this Agreement for any reason. Any such charge in effect at the time of a particular transaction shall be the charge for that transaction, notwithstanding any subsequent change in the Issuer’s prevailing charges for that type of transaction. All Letter of Credit Fees payable hereunder shall be deemed earned in full on the date when the same are due and payable hereunder and shall not be subject to rebate or pro-ration upon the termination of this Agreement for any reason.

Amended & Restated Credit Agreement

     On demand, Borrowers will cause cash to be deposited and maintained in an account with Agent, as cash collateral, in an amount equal to one hundred and five percent (105%) of the Maximum Undrawn Amount of all outstanding Letters of Credit, and each Borrower hereby irrevocably authorizes Agent, in its discretion, on such Borrower’s behalf and in such Borrower’s name, to open such an account and to make and maintain deposits therein, or in an account opened by such Borrower, in the amounts required to be made by such Borrower, out of the proceeds of Receivables or other Collateral or out of any other funds of such Borrower coming into any Lender’s possession at any time. Agent will invest such cash collateral (less applicable reserves) in such short-term money-market items as to which Agent and such Borrower mutually agree and the net return on such investments shall be credited to such account and constitute additional cash collateral. No Borrower may withdraw amounts credited to any such account except upon the occurrence of all of the following: (x) payment and performance in full of all Obligations, (y) expiration of all Letters of Credit and (z) termination of this Agreement.

     3.3. Closing Fee and Facility Fee.

          (a) Closing Fee. Upon the execution of this Agreement, Borrowers shall pay to Agent a closing fee of $75,000.00.

          (b) Facility Fee. If, for any month during the Term, the average daily unpaid balance of the Revolving Advances and undrawn amount of any outstanding Letters of Credit for each day of such month does not equal the Maximum Revolving Advance Amount and/or the average daily unpaid balance of the CapEx Loans for each day of such month does not equal the Maximum CapEx Loan Amount, then Borrowers shall pay to Agent for the ratable benefit of Lenders a fee at a rate equal to one-quarter of one percent (.25%) per annum on the amount by which the Maximum Revolving Advance Amount and/or Maximum CapEx Loan Amount (as applicable) exceeds such average daily unpaid balance. Such fee shall be payable to each Lender (in proportion to such Lender’s commitment) in arrears on the first day of each month with respect to the previous month.

     3.4. Collateral Evaluation Fee, Collateral Monitoring Fee; Late Reporting Fee.

          (a) Collateral Evaluation Fee. Borrowers shall pay Agent a collateral evaluation fee equal to $1,250.00 per month commencing on the first day of the month following the Restated Closing Date and on the first day of each month thereafter during the Term. The collateral evaluation fee shall be deemed earned in full on the date when same is due and payable hereunder and shall not be subject to rebate or proration upon termination of this Agreement for any reason.

          (b) Collateral Monitoring Fee. Borrowers shall pay to Agent on the first day of each month following any month in which Agent performs any collateral monitoring — namely any field examination, collateral analysis or other business analysis, the need for which is to be determined by Agent and which monitoring is undertaken by Agent or for Agent’s benefit — a collateral monitoring fee in an amount of at least $750.00 per day (subject to change from time to time based on market rates) for each person employed to perform such monitoring, plus all costs and disbursements incurred by Agent in the performance of such examination or analysis.

Amended & Restated Credit Agreement

          (c) Late Reporting Fee. At Agent’s option, Borrowers shall pay to Agent a late reporting fee in the amount of $500.00 per day, for each report or other deliverable required on or after January 1, 2007, under Sections 9.7, 9.8, 9.9, 9.10, 9.11 and 9.13 which is not received by Agent on the date such report or deliverable is due.

     3.5. Computation of Interest and Fees. Interest and fees hereunder shall be computed on the basis of a year of 360 days and for the actual number of days elapsed. If any payment to be made hereunder becomes due and payable on a day other than a Business Day, the due date thereof shall be extended to the next succeeding Business Day and interest thereon shall be payable at the applicable Contract Rate during such extension.

     3.6. Maximum Charges. It is the intention of the parties to comply strictly with applicable usury laws. Accordingly, notwithstanding any provision to the contrary in this Agreement or the Other Documents, in no event shall any Obligations require the payment or permit the payment, taking, reserving, receiving, collection or charging of any sums constituting interest under Applicable Laws that exceed the maximum amount permitted by such laws, as the same may be amended or modified from time to time (the “Maximum Rate”). If any such excess interest is called for, contracted for, charged, taken, reserved or received in connection herewith or therewith, or in any communication by Agent, any Lender or any other Person to Borrower, any Guarantor or any other Person liable for the Obligations, or in the event that all or part of the principal or interest hereof or thereof shall be prepaid or accelerated, so that under any of such circumstances or under any other circumstance whatsoever the amount of interest contracted for, charged, taken, reserved or received on the amount of principal actually outstanding from time to time under the Obligations shall exceed the Maximum Rate, then in such event it is agreed that: (a) the provisions of this paragraph shall govern and control; (b) neither Borrower, any Guarantor nor any other Person now or hereafter liable for the payment of any of the Obligations shall be obligated to pay the amount of such interest to the extent it is in excess of the Maximum Rate; (c) any such excess interest which is or has been received by Agent or any Lender, notwithstanding this paragraph, shall be credited against the then unpaid principal balance of the Obligations (or, if the principal amount of the Obligations shall have been paid in full, refunded by Lenders to the party primarily liable on the Obligation, and each Lender shall refund its pro rat share of such interest); and (d) the provisions of this Agreement and the Obligations, and any other communication to Borrower or any Guarantor, shall immediately be deemed reformed and such excess interest reduced, without the necessity of executing any other document, to the Maximum Rate. The right to accelerate the maturity of the Obligations does not include the right to accelerate, collect or charge unearned interest, but only such interest that has otherwise accrued as of the date of acceleration. Without limiting the foregoing, all calculations of the rate of interest contracted for, charged, taken, reserved or received in connection with any of the Obligations which are made for the purpose of determining whether such rate exceeds the Maximum Rate shall be made to the extent permitted by Applicable Laws by amortizing, prorating, allocating and spreading during the period of the full term of such Obligations, including all prior and subsequent renewals and extensions hereof or thereof, all interest at any time contracted for, charged, taken, reserved or received by Agent or any Lender. To the extent that either Chapter 303 or 306, or both, of the Texas Finance Code apply in determining the Maximum Rate, Agent and Lenders hereby elect to determine the applicable rate ceiling by using the weekly ceiling from time to time in effect, subject to Agent’s right subsequently to change

Amended & Restated Credit Agreement

such method in accordance with Applicable Law, as the same may be amended or modified from time to time.

     3.7. Increased Costs. In the event that any Applicable Law, treaty or governmental regulation, or any change therein or in the interpretation or application thereof, or compliance by any Lender (for purposes of this Section 3.7, the term “Lender” shall include Agent or any Lender and any corporation or bank controlling Agent or any Lender) and the office or branch where Agent or any Lender (as so defined) makes or maintains any Eurodollar Rate Loans with any request or directive (whether or not having the force of law) from any central bank or other financial, monetary or other authority, shall:

          (a) subject Agent or any Lender to any tax of any kind whatsoever with respect to this Agreement or any Other Document or change the basis of taxation of payments to Agent or any Lender of principal, fees, interest or any other amount payable hereunder or under any Other Documents (except for changes in the rate of tax on the overall net income of Agent or any Lender by the jurisdiction in which it maintains its principal office);

          (b) impose, modify or hold applicable any reserve, special deposit, assessment or similar requirement against assets held by, or deposits in or for the account of, advances or loans by, or other credit extended by, any office of Agent or any Lender, including pursuant to Regulation D of the Board of Governors of the Federal Reserve System; or

          (c) impose on Agent or any Lender or the London interbank Eurodollar market any other condition with respect to this Agreement or any Other Document;

     and the result of any of the foregoing is to increase the cost to Agent or any Lender of making, renewing or maintaining its Advances hereunder by an amount that Agent or such Lender deems to be material or to reduce the amount of any payment (whether of principal, interest or otherwise) in respect of any of the Advances by an amount that Agent or such Lender deems to be material, then, in any case Borrowers shall promptly pay Agent or such Lender, upon its demand, such additional amount as will compensate Agent or such Lender for such additional cost or such reduction, as the case may be, provided that the foregoing shall not apply to increased costs which are reflected in the Eurodollar Rate, as the case may be. Agent or such Lender shall certify the amount of such additional cost or reduced amount to Borrowing Agent, and such certification shall be conclusive absent manifest error.

     3.8. Basis For Determining Interest Rate Inadequate or Unfair. In the event that Agent or any Lender shall have determined that:

          (a) reasonable means do not exist for ascertaining the Eurodollar Rate applicable pursuant to Section 2.2 hereof for any Interest Period; or

          (b) Dollar deposits in the relevant amount and for the relevant maturity are not available in the London interbank Eurodollar market, with respect to an outstanding Eurodollar Rate Loan, a proposed Eurodollar Rate Loan, or a proposed conversion of a Domestic Rate Loan into a Eurodollar Rate Loan, then Agent shall give Borrowing Agent prompt written, telephonic or telegraphic notice of such determination. If such notice is given, (i) any such requested Eurodollar Rate Loan shall be made as a Domestic Rate Loan, unless Borrowing Agent shall

     3.9. Capital Adequacy.

          (a) In the event that Agent or any Lender shall have determined that any Applicable Law, rule, regulation or guideline regarding capital adequacy, or any change therein, or any change in the interpretation or administration thereof by any Governmental Body, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by Agent or any Lender (for purposes of this Section 3.9, the term “Lender” shall include Agent or any Lender and any corporation or bank controlling Agent or any Lender) and the office or branch where Agent or any Lender (as so defined) makes or maintains any Eurodollar Rate Loans with any request or directive regarding capital adequacy (whether or not having the force of law) of any such authority, central bank or comparable agency, has or would have the effect of reducing the rate of return on Agent or any Lender’s capital as a consequence of its obligations hereunder to a level below that which Agent or such Lender could have achieved but for such adoption, change or compliance (taking into consideration Agent’s and each Lender’s policies with respect to capital adequacy) by an amount deemed by Agent or any Lender to be material, then, from time to time, Borrowers shall pay upon demand to Agent or such Lender such additional amount or amounts as will compensate Agent or such Lender for such reduction. In determining such amount or amounts, Agent or such Lender may use any reasonable averaging or attribution methods. The protection of this Section 3.9 shall be available to Agent and each Lender regardless of any possible contention of invalidity or inapplicability with respect to the Applicable Law, regulation or condition.

          (b) A certificate of Agent or such Lender setting forth such amount or amounts as shall be necessary to compensate Agent or such Lender with respect to Section 3.9(a) hereof when delivered to Borrowing Agent shall be conclusive absent manifest error.

     3.10. Gross Up for Taxes. If any Borrower shall be required by Applicable Law to withhold or deduct any taxes from or in respect of any sum payable under this Agreement or any of the Other Documents to Agent, or any Lender, assignee of any Lender, or Participant (each, individually, a “Payee” and collectively, the “Payees”), (a) the sum payable to such Payee or

Amended & Restated Credit Agreement

Payees, as the case may be, shall be increased as may be necessary so that, after making all required withholding or deductions, the applicable Payee or Payees receives an amount equal to the sum it would have received had no such withholding or deductions been made (the “Gross-Up Payment”), (b) such Borrower shall make such withholding or deductions, and (c) such Borrower shall pay the full amount withheld or deducted to the relevant taxation authority or other authority in accordance with Applicable Law. Notwithstanding the foregoing and only with respect to any withholdings or deductions for taxes payable pursuant to the laws of the United States of America or any state or jurisdiction thereof, no Borrower shall be obligated to make any portion of the Gross-Up Payment that is attributable to any withholding or deductions that would not have been paid or claimed had the applicable Payee or Payees properly claimed a complete exemption with respect thereto pursuant to Section 3.11 hereof.

     3.11. Withholding Tax Exemption.

          (a) Each Payee that is not incorporated under the Laws of the United States of America or a state thereof (and, upon the written request of Agent, each other Payee) agrees that it will deliver to Borrowing Agent and Agent two (2) duly completed appropriate valid Withholding Certificates (as defined under §1.1441-1(c)(16) of the Income Tax Regulations (“Regulations”)) certifying its status (i.e., U.S. or foreign person) and, if appropriate, making a claim of reduced, or exemption from, U.S. withholding tax on the basis of an income tax treaty or an exemption provided by the Code. The term “Withholding Certificate” means a Form W-9; a Form W-8BEN; a Form W-8ECI; a Form W-8IMY and the related statements and certifications as required under §1.1441-1(e)(2) and/or (3) of the Regulations; a statement described in §1.871-14(c)(2)(v) of the Regulations; or any other certificates under the Code or Regulations that certify or establish the status of a payee or beneficial owner as a U.S. or foreign person.

          (b) Each Payee required to deliver to Borrowing Agent and Agent a valid Withholding Certificate pursuant to Section 3.11(a) hereof shall deliver such valid Withholding Certificate as follows: (A) each Payee which is a party hereto on the Restated Closing Date shall deliver such valid Withholding Certificate at least five (5) Business Days prior to the first date on which any interest or fees are payable by any Borrower hereunder for the account of such Payee; (B) each Payee shall deliver such valid Withholding Certificate at least five (5) Business Days before the effective date of such assignment or participation (unless Agent in its sole discretion shall permit such Payee to deliver such Withholding Certificate less than five (5) Business Days before such date in which case it shall be due on the date specified by Agent). Each Payee which so delivers a valid Withholding Certificate further undertakes to deliver to Borrowing Agent and Agent two (2) additional copies of such Withholding Certificate (or a successor form) on or before the date that such Withholding Certificate expires or becomes obsolete or after the occurrence of any event requiring a change in the most recent Withholding Certificate so delivered by it, and such amendments thereto or extensions or renewals thereof as may be reasonably requested by Borrowing Agent or Agent.

          (c) Notwithstanding the submission of a Withholding Certificate claiming a reduced rate of or exemption from U.S. withholding tax required under Section 3.11(b) hereof, Agent shall be entitled to withhold United States federal income taxes at the full 30% withholding rate if in its reasonable judgment it is required to do so under the due diligence

Amended & Restated Credit Agreement

requirements imposed upon a withholding agent under §1.1441-7(b) of the Regulations. Further, Agent is indemnified under §1.1461-1(e) of the Regulations against any claims and demands of any Payee for the amount of any tax it deducts and withholds in accordance with regulations under §1441 of the Code.

     4.6. Defense of Agent’s and Lenders’ Interests. Until (a) payment and performance in full of all of the Obligations and (b) termination of this Agreement, Agent’s interests in the Collateral shall continue in full force and effect.

Each Borrower hereby authorizes all

Amended & Restated Credit Agreement

Governmental Bodies to furnish to Agent and each Lender copies of reports or examinations relating to such Borrower, whether made by such Borrower or otherwise; however, Agent and each Lender will attempt to obtain such information or materials directly from such Borrower prior to obtaining such information or materials from such accountants or Governmental Bodies.

     4.9. Compliance with Laws. Each Borrower shall comply with all Applicable Laws with respect to the Collateral or any part thereof or to the operation of such Borrower’s business the non-compliance with which could reasonably be expected to have a Material Adverse Effect. Each Borrower may, however, contest or dispute any Applicable Laws in any reasonable manner, provided that any related Lien is inchoate or stayed and sufficient reserves are established to the reasonable satisfaction of Agent to protect Agent’s Lien on or security interest in the Collateral. The assets of Borrowers at all times shall be maintained in accordance with the requirements of all insurance carriers which provide insurance with respect to the assets of Borrowers so that such insurance shall remain in full force and effect.

     4.10. Inspection of Premises.

     4.11. Insurance. The assets and properties of each Borrower at all times shall be maintained in accordance with the requirements of all insurance carriers which provide insurance with respect to the assets and properties of such Borrower so that such insurance shall remain in full force and effect. Each Borrower shall bear the full risk of any loss of any nature whatsoever with respect to the Collateral. At each Borrower’s own cost and expense in amounts and with carriers acceptable to Agent, each Borrower shall (a) keep all its insurable properties and properties in which such Borrower has an interest insured against the hazards of fire, flood, sprinkler leakage, those hazards covered by extended coverage insurance and such other hazards, and for such amounts, as is customary in the case of companies engaged in businesses similar to such Borrower’s; (b) maintain public and, if applicable, product liability insurance against claims for personal injury, death or property damage suffered by others; (c) maintain all such worker’s compensation or similar insurance as may be required under the laws of any state or jurisdiction in which such Borrower is engaged in business; (d) furnish Agent with (i) copies of all policies and evidence of the maintenance of such policies by the renewal thereof at least thirty (30) days before any expiration date, and (ii) appropriate loss payable endorsements in form and substance satisfactory to Agent, naming Agent as a co-insured and loss payee as its interests may appear with respect to all insurance coverage referred to in clauses (a) and (c) above, and providing (A) that all proceeds thereunder shall be payable to Agent, (B) no such insurance shall be affected by any act or neglect of the insured or owner of the property described in such policy, and (C) that such policy and loss payable clauses may not be cancelled, amended or terminated unless at least thirty (30) days’ prior written notice is given to Agent. In the event of any loss thereunder, the carriers named therein hereby are directed by Agent and the applicable Borrower

Amended & Restated Credit Agreement

to make payment for such loss to Agent and not to such Borrower and Agent jointly. If any insurance losses are paid by check, draft or other instrument payable to any Borrower and Agent jointly, Agent may endorse such Borrower’s name thereon and do such other things as Agent may deem advisable to reduce the same to cash. Agent is hereby authorized to adjust and compromise claims under insurance coverage referred to in clauses (a) and (b) above. All loss recoveries received by Agent upon any such insurance may be applied to the Obligations, in such order as Agent in its sole discretion shall determine. Any surplus shall be paid by Agent to Borrowers or applied as may be otherwise required by law. Any deficiency thereon shall be paid by Borrowers to Agent, on demand.

     4.12. Failure to Pay Insurance. If any Borrower fails to obtain insurance as hereinabove provided, or to keep the same in force, Agent, if Agent so elects, may obtain such insurance and pay the premium therefor on behalf of such Borrower, and charge Borrowers’ Account therefor as a Revolving Advance of a Domestic Rate Loan and such expenses so paid shall be part of the Obligations.

     4.13. Payment of Taxes. Each Borrower will pay, when due, all taxes, assessments and other Charges lawfully levied or assessed upon such Borrower or any of the Collateral including real and personal property taxes, assessments and charges and all franchise, income, employment, social security benefits, withholding, and sales taxes unless such Borrower is contesting such taxes in good faith, by appropriate proceedings, and is maintaining adequate reserves for such taxes in accordance with GAAP. Notwithstanding the foregoing, if a Lien securing any such taxes is filed in any public office and such Lien is not a Permitted Lien, then the Borrowers shall pay all taxes secured by such Lien immediately and remove such Lien of record promptly. If any tax by any Governmental Body is or may be imposed on or as a result of any transaction between any Borrower and Agent or any Lender which Agent or any Lender may be required to withhold or pay or if any taxes, assessments, or other Charges remain unpaid after the date fixed for their payment, or if any claim shall be made which, in Agent’s or any Lender’s opinion, may possibly create a valid Lien on the Collateral, Agent may without notice to Borrowers pay the taxes, assessments or other Charges and each Borrower hereby agrees to indemnify, defend and hold Agent and each Lender harmless in respect thereof. The amount of any payment by Agent under this Section 4.13 shall be charged to Borrowers’ Account as a Revolving Advance and added to the Obligations and, until Borrowers shall furnish Agent with an indemnity therefor (or supply Agent with evidence satisfactory to Agent that due provision for the payment thereof has been made), Agent may hold without interest any balance standing to Borrowers’ credit and Agent shall retain its security interest in and Lien on any and all Collateral held by Agent.

     4.14. Payment of Leasehold Obligations. Each Borrower shall at all times pay, when and as due, its rental obligations under all leases under which it is a tenant, and shall otherwise comply, in all material respects, with all other terms of such leases and keep them in full force and effect and, at Agent’s request will provide evidence of having done so.

     4.15. Receivables.

          (a) Nature of Receivables. Each of the Receivables shall be a bona fide and valid account representing a bona fide indebtedness incurred by the Customer therein named, for

          (d) Collection of Receivables. Until any Borrower’s authority to do so is terminated by Agent (which notice Agent may give at any time following the occurrence of an Event of Default or a Default or when Agent in its sole discretion deems it to be in Lenders’ best interest to do so), each Borrower will, at such Borrower’s sole cost and expense, but on Agent’s behalf and for Agent’s account, collect as Agent’s property and in trust for Agent all amounts received on Receivables, and shall not commingle such collections with any Borrower’s funds or use the same except to pay Obligations.

          (e) Notification of Assignment of Receivables. At any time, Agent shall have the right to send notice of the assignment of, and Agent’s security interest in and Lien on, the Receivables to any and all Customers or any third party holding or otherwise concerned with any of the Collateral. Thereafter, Agent shall have the sole right to collect the Receivables, take possession of the Collateral, or both.

Agent shall have the right at any time to change the address for delivery of mail addressed to any Borrower to such address as Agent may designate and to receive, open and dispose of all mail addressed to any Borrower.

XI            LENDERS’ RIGHTS AND REMEDIES AFTER DEFAULT.

     11.1. Rights and Remedies.

Amended & Restated Credit Agreement

          (a) Upon the occurrence of (i) an Event of Default pursuant to Section 10.7 all Obligations shall be immediately due and payable and this Agreement and the obligation of Lenders to make Advances shall be deemed terminated; and, (ii) any of the other Events of Default and at any time thereafter (such default not having previously been cured), at the option of Required Lenders all Obligations shall be immediately due and payable and Lenders shall have the right to terminate this Agreement and to terminate the obligation of Lenders to make Advances and (iii) a filing of a petition against any Borrower in any involuntary case under any state or federal bankruptcy laws, all Obligations shall be immediately due and payable and the obligation of Lenders to make Advances hereunder shall be terminated other than as may be required by an appropriate order of the bankruptcy court having jurisdiction over such Borrower. Upon the occurrence of any Event of Default, Agent shall have the right to exercise any and all rights and remedies provided for herein, under the Other Documents, under the Uniform Commercial Code and at law or equity generally, including the right to foreclose the security interests granted herein and to realize upon any Collateral by any available judicial procedure and/or to take possession of and sell any or all of the Collateral with or without judicial process. Agent may enter any of any Borrower’s premises or other premises without legal process and without incurring liability to any Borrower therefor, and Agent may thereupon, or at any time thereafter, in its discretion without notice or demand, take the Collateral and remove the same to such place as Agent may deem advisable and Agent may require Borrowers to make the Collateral available to Agent at a convenient place. With or without having the Collateral at the time or place of sale, Agent may sell the Collateral, or any part thereof, at public or private sale, at any time or place, in one or more sales, at such price or prices, and upon such terms, either for cash, credit or future delivery, as Agent may elect. Except as to that part of the Collateral which is perishable or threatens to decline speedily in value or is of a type customarily sold on a recognized market, Agent shall give Borrowers reasonable notification of such sale or sales, it being agreed that in all events written notice mailed to Borrowing Agent at least ten (10) days prior to such sale or sales is reasonable notification. At any public sale Agent or any Lender may bid for and become the purchaser, and Agent, any Lender or any other purchaser at any such sale thereafter shall hold the Collateral sold absolutely free from any claim or right of whatsoever kind, including any equity of redemption and all such claims, rights and equities are hereby expressly waived and released by each Borrower. In connection with the exercise of the foregoing remedies, including the sale of Inventory, Agent is granted a perpetual nonrevocable, royalty free, nonexclusive license and Agent is granted permission to use all of each Borrower’s (a) trademarks, trade styles, trade names, patents, patent applications, copyrights, service marks, licenses, franchises and other proprietary rights which are used or useful in connection with Inventory for the purpose of marketing, advertising for sale and selling or otherwise disposing of such Inventory and (b) Equipment for the purpose of completing any unfinished job, contract, project or assignment as deemed necessary by Agent. The cash proceeds realized from the sale of any Collateral shall be applied to the Obligations in the order set forth in Section 11.5 hereof. Noncash proceeds will only be applied to the Obligations as they are converted into cash. If any deficiency shall arise, Borrowers shall remain liable to Agent and Lenders therefor.

          (b) To the extent that Applicable Law imposes duties on the Agent to exercise remedies in a commercially reasonable manner, each Borrower acknowledges and agrees that it is not commercially unreasonable for the Agent (i) to fail to incur expenses reasonably deemed significant by the Agent to prepare Collateral for disposition or otherwise to complete raw material or work in process into finished goods or other finished products for disposition, (ii) to

Amended & Restated Credit Agreement

fail to obtain third party consents for access to Collateral to be disposed of, or to obtain or, if not required by other law, to fail to obtain governmental or third party consents for the collection or disposition of Collateral to be collected or disposed of, (iii) to fail to exercise collection remedies against Customers or other Persons obligated on Collateral or to remove Liens on or any adverse claims against Collateral, (iv) to exercise collection remedies against Customers and other Persons obligated on Collateral directly or through the use of collection agencies and other collection specialists, (v) to advertise dispositions of Collateral through publications or media of general circulation, whether or not the Collateral is of a specialized nature, (vi) to contact other Persons, whether or not in the same business as any Borrower, for expressions of interest in acquiring all or any portion of such Collateral, (vii) to hire one or more professional auctioneers to assist in the disposition of Collateral, whether or not the Collateral is of a specialized nature, (viii) to dispose of Collateral by utilizing internet sites that provide for the auction of assets of the types included in the Collateral or that have the reasonable capacity of doing so, or that match buyers and sellers of assets, (ix) to dispose of assets in wholesale rather than retail markets, (x) to disclaim disposition warranties, such as title, possession or quiet enjoyment, (xi) to purchase insurance or credit enhancements to insure the Agent against risks of loss, collection or disposition of Collateral or to provide to the Agent a guaranteed return from the collection or disposition of Collateral, or (xii) to the extent deemed appropriate by the Agent, to obtain the services of other brokers, investment bankers, consultants and other professionals to assist the Agent in the collection or disposition of any of the Collateral. Each Borrower acknowledges that the purpose of this Section 11.1(b) is to provide non-exhaustive indications of what actions or omissions by the Agent would not be commercially unreasonable in the Agent’s exercise of remedies against the Collateral and that other actions or omissions by the Agent shall not be deemed commercially unreasonable solely on account of not being indicated in this Section 11.1(b). Without limitation upon the foregoing, nothing contained in this Section 11.1(b) shall be construed to grant any rights to any Borrower or to impose any duties on Agent that would not have been granted or imposed by this Agreement or by Applicable Law in the absence of this Section 11.1(b).

          (c) With respect to Exploration and any Collateral held or owned by it, upon the occurrence of and during the continuance of any Event of Default, Agent may appoint or reappoint by instrument in writing, any Person or Persons, whether an officer or officers or an employee or employees of Agent or not, to be an interim receiver, receiver or receivers (hereinafter called a “Receiver”, which term when used herein shall include a receiver and manager) of Collateral (including any interest, income or profits therefrom) and may remove any Receiver so appointed and appoint another in his/her/its stead. Any such Receiver shall, so far as concerns responsibility for his/her/its acts, be deemed the agent of Exploration and not Agent and Agent shall not be in any way responsible for any misconduct, negligence or non-feasance on the part of any such Receiver or his/her/its servants, agents or employees. Subject to the provisions of the instrument appointing him/her/it, any such Receiver shall have power to take possession of Collateral, to preserve Collateral or its value, to carry on or concur in carrying on all or any part of the business of Exploration and to sell, lease, license or otherwise dispose of or concur in selling, leasing, licensing or otherwise disposing of Collateral. To facilitate the foregoing powers, any such Receiver may, to the exclusion of all others, including Agent, enter upon, use and occupy all premises owned or occupied by Agent wherein Collateral may be situate, maintain Collateral upon such premises, borrow money on a secured or unsecured basis and use Collateral directly in carrying on the business of Exploration or as security for loans or

Amended & Restated Credit Agreement

advances to enable the Receiver to carry on the business or Exploration or otherwise, as such Receiver shall, in its discretion, determine. Except as may be otherwise directed by Agent, all money received from time to time by such Receiver in carrying out his/her/its appointment shall be received in trust for and be paid over to Agent. Every such Receiver may, in the discretion of Agent, be vested with all or any of the rights and powers of Agent.

     11.2. Agent’s Discretion. Agent shall have the right in its sole discretion to determine which rights, Liens, security interests or remedies Agent may at any time pursue, relinquish, subordinate, or modify or to take any other action with respect thereto and such determination will not in any way modify or affect any of Agent’s or Lenders’ rights hereunder.

     11.3. Setoff. Subject to Section 14.12, in addition to any other rights which Agent or any Lender may have under Applicable Law, upon the occurrence of an Event of Default hereunder, Agent and such Lender shall have a right, immediately and without notice of any kind, to apply any Borrower’s property held by Agent and such Lender to reduce the Obligations.

     11.4. Rights and Remedies not Exclusive. The enumeration of the foregoing rights and remedies is not intended to be exhaustive and the exercise of any rights or remedy shall not preclude the exercise of any other right or remedies provided for herein or otherwise provided by law, all of which shall be cumulative and not alternative.

     11.5. Allocation of Payments After Event of Default. Notwithstanding any other provisions of this Agreement to the contrary, after the occurrence and during the continuance of an Event of Default, all amounts collected or received by the Agent on account of the Obligations or any other amounts outstanding under any of the Other Documents or in respect of the Collateral may, at Agent’s discretion, be paid over or delivered as follows:

     In carrying out the foregoing, (i) amounts received shall be applied in the numerical order provided until exhausted prior to application to the next succeeding category; (ii) each of the Lenders shall receive (so long as it is not a Defaulting Lender) an amount equal to its pro rata share (based on the proportion that the then outstanding Advances held by such Lender bears to the aggregate then outstanding Advances) of amounts available to be applied pursuant to clauses “FOURTH”, “FIFTH” and “SIXTH” above; and (iii) to the extent that any amounts available for distribution pursuant to clause “FIFTH” above are attributable to the issued but undrawn amount of outstanding Letters of Credit, such amounts shall be held by the Agent in a cash collateral account and applied (A) first, to reimburse the Issuer from time to time for any drawings under such Letters of Credit and (B) then, following the expiration of all Letters of Credit, to all other obligations of the types described in clauses “FIFTH” and “SIXTH” above in the manner provided in this Section 11.5.

XIII EFFECTIVE DATE AND TERMINATION.

     13.1. Term. This Agreement, which shall inure to the benefit of and shall be binding upon the respective successors and permitted assigns of each Borrower, Agent and each Lender, shall become effective on the date hereof and shall continue in full force and effect until December 15, 2011 (the “Term”) unless sooner terminated as herein provided. Borrowers may terminate this Agreement at any time upon ninety (90) days’ prior written notice upon payment in full of the Obligations. In the event the Obligations are prepaid in full and all commitments to lend hereunder are terminated prior to the last day of the Term (the date of such prepayment hereinafter referred to as the “Early Termination Date”), Borrowers shall pay to Agent for the benefit of Lenders an early termination fee in an amount equal to (x) $600,000.00 if the Early Termination Date occurs on or after the Restated Closing Date to and including the date immediately preceding the first anniversary of the Restated Closing Date, (y) $450,000.00 if the Early Termination Date occurs on or after the first anniversary of the Restated Closing Date to and including the date immediately preceding the second anniversary of the Restated Closing Date or (z) $150,000.00 if the Early Termination Date occurs on or after the second anniversary of the Restated Closing Date, but before the date that is thirty (30) days prior to the end of the Term; provided, however that such early termination fees shall not apply to new financing arranged by Agent.

     13.2. Termination.

The security interests, Liens and rights granted to Agent and Lenders hereunder and the financing statements filed hereunder shall continue in full force and effect, notwithstanding the termination of this Agreement or the fact that Borrowers’ Account may from time to time be temporarily in a zero or credit position, until all of the Obligations of each Borrower have been indefeasibly paid and performed in full after the termination of this Agreement or each Borrower has furnished Agent and Lenders with an indemnification satisfactory to Agent and Lenders with respect thereto. Accordingly, each Borrower waives any rights which it may have under the Uniform Commercial Code to demand

Amended & Restated Credit Agreement

the filing of termination statements with respect to the Collateral, and Agent shall not be required to send such termination statements to each Borrower, or to file them with any filing office, unless and until this Agreement shall have been terminated in accordance with its terms and all Obligations have been indefeasibly paid in full in immediately available funds. All representations, warranties, covenants, waivers and agreements contained herein shall survive termination hereof until all Obligations are indefeasibly paid and performed in full.

XIV            REGARDING AGENT.

     14.1. Appointment. Each Lender hereby designates PNC to act as Agent for such Lender under this Agreement and the Other Documents. Each Lender hereby irrevocably authorizes Agent to take such action on its behalf under the provisions of this Agreement and the Other Documents and to exercise such powers and to perform such duties hereunder and thereunder as are specifically delegated to or required of Agent by the terms hereof and thereof and such other powers as are reasonably incidental thereto and Agent shall hold all Collateral, payments of principal and interest, fees (except the fees set forth in Sections 3.3(a) and 3.4), charges and collections (without giving effect to any collection days) received pursuant to this Agreement, for the ratable benefit of Lenders. Agent may perform any of its duties hereunder by or through its agents or employees. As to any matters not expressly provided for by this Agreement (including collection of the Note) 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 Required Lenders, and such instructions shall be binding; provided, however, that Agent shall not be required to take any action which exposes Agent to liability or which is contrary to this Agreement or the Other Documents or Applicable Law unless Agent is furnished with an indemnification reasonably satisfactory to Agent with respect thereto.

     14.2. Nature of Duties. Agent shall have no duties or responsibilities except those expressly set forth in this Agreement and the Other Documents. Neither Agent nor any of its officers, directors, employees or agents shall be (i) liable for any action taken or omitted by them as such hereunder or in connection herewith, unless caused by their gross (not mere) negligence or willful misconduct (as determined by a court of competent jurisdiction in a final non-appealable judgment), or (ii) responsible in any manner for any recitals, statements, representations or warranties made by any Borrower or any officer thereof contained in this Agreement, or in any of the Other Documents or in any certificate, report, statement or other document referred to or provided for in, or received by Agent under or in connection with, this Agreement or any of the Other Documents or for the value, validity, effectiveness, genuineness, due execution, enforceability or sufficiency of this Agreement, or any of the Other Documents or for any failure of any Borrower to perform its obligations hereunder. Agent shall not be under any obligation to any Lender to ascertain or to inquire as to the observance or performance of any of the agreements contained in, or conditions of, this Agreement or any of the Other Documents, or to inspect the properties, books or records of any Borrower. The duties of Agent as respects the Advances to Borrowers shall be mechanical and administrative in nature; Agent shall not have by reason of this Agreement a fiduciary relationship in respect of any Lender; and nothing in this Agreement, expressed or implied, is intended to or shall be so construed as to impose upon Agent any obligations in respect of this Agreement except as expressly set forth herein.

Amended & Restated Credit Agreement

     14.3. Lack of Reliance on Agent and Resignation. Independently and without reliance upon Agent or any other Lender, each Lender has made and shall continue to make (i) its own independent investigation of the financial condition and affairs of each Borrower and any Guarantor in connection with the making and the continuance of the Advances hereunder and the taking or not taking of any action in connection herewith, and (ii) its own appraisal of the creditworthiness of each Borrower and any Guarantor. Agent shall have no duty or responsibility, either initially or on a continuing basis, to provide any Lender with any credit or other information with respect thereto, whether coming into its possession before making of the Advances or at any time or times thereafter except as shall be provided by any Borrower pursuant to the terms hereof. Agent shall not be responsible to any Lender for any recitals, statements, information, representations or warranties herein or in any agreement, document, certificate or a statement delivered in connection with or for the execution, effectiveness, genuineness, validity, enforceability, collectability or sufficiency of this Agreement or any Other Document, or of the financial condition of any Borrower or any Guarantor, or be required to make any inquiry concerning either the performance or observance of any of the terms, provisions or conditions of this Agreement, the Note, the Other Documents or the financial condition of any Borrower, or the existence of any Event of Default or any Default.

     Agent may resign on sixty (60) days’ written notice to each of Lenders and Borrowing Agent and upon such resignation, the Required Lenders will promptly designate a successor Agent reasonably satisfactory to Borrowers.

     Any such successor Agent shall succeed to the rights, powers and duties of Agent, and the term “Agent” shall mean such successor agent effective upon its appointment, and the former Agent’s rights, powers and duties as Agent shall be terminated, without any other or further act or deed on the part of such former Agent. After any Agent’s resignation as Agent, the provisions of this Article XIV shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Agent under this Agreement.

     14.4. Certain Rights of Agent. If Agent shall request instructions from Lenders with respect to any act or action (including failure to act) in connection with this Agreement or any Other Document, Agent shall be entitled to refrain from such act or taking such action unless and until Agent shall have received instructions from the Required Lenders; and Agent shall not incur liability to any Person by reason of so refraining. Without limiting the foregoing, Lenders shall not have any right of action whatsoever against Agent as a result of its acting or refraining from acting hereunder in accordance with the instructions of the Required Lenders.

     14.5. Reliance. Agent shall be entitled to rely, and shall be fully protected in relying, upon any note, writing, resolution, notice, statement, certificate, telex, teletype or telecopier message, cablegram, order or other document or telephone message believed by it to be genuine and correct and to have been signed, sent or made by the proper person or entity, and, with respect to all legal matters pertaining to this Agreement and the Other Documents and its duties hereunder, upon advice of counsel selected by it. Agent may employ agents and attorneys-in-fact and shall not be liable for the default or misconduct of any such agents or attorneys-in-fact selected by Agent with reasonable care.

Amended & Restated Credit Agreement

     14.6. Notice of Default. Agent shall not be deemed to have knowledge or notice of the occurrence of any Default or Event of Default hereunder or under the Other Documents, unless Agent has received notice from a Lender or Borrowing Agent referring to this Agreement or the Other Documents, describing such Default or Event of Default and stating that such notice is a “NOTICE OF DEFAULT”. In the event that Agent receives such a notice, Agent shall give notice thereof to Lenders. Agent shall take such action with respect to such Default or Event of Default as shall be reasonably directed by the Required Lenders; provided, that, unless and until Agent shall have received such directions, Agent may (but shall not be obligated to) take such action, or refrain from taking such action, with respect to such Default or Event of Default as it shall deem advisable in the best interests of Lenders.

     14.7. Indemnification. To the extent Agent is not reimbursed and indemnified by Borrowers, each Lender will reimburse and indemnify Agent in proportion to its respective portion of the Advances (or, if no Advances are outstanding, according to its Commitment Percentage), 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 Agent in performing its duties hereunder, or in any way relating to or arising out of this Agreement or any Other Document (INCLUDING, WITHOUT LIMITATION, WITH RESPECT TO ANY OTHERWISE INDEMNIFIED MATTER ARISING FROM AGENT’S NEGLIGENCE OR STRICT LIABILITY BUT NOT AGENT’S GROSS NEGLIGENCE OR WILLFUL MISCONDUCT); provided that, Lenders shall not be liable for any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements resulting from Agent’s gross (not mere) negligence or willful misconduct (as determined by a court of competent jurisdiction in a final non-appealable judgment).

     14.8. Agent in its Individual Capacity. With respect to the obligation of Agent to lend under this Agreement, the Advances made by it shall have the same rights and powers hereunder as any other Lender and as if it were not performing the duties as Agent specified herein; and the term “Lender” or any similar term shall, unless the context clearly otherwise indicates, include Agent in its individual capacity as a Lender. Agent may engage in business with any Borrower as if it were not performing the duties specified herein, and may accept fees and other consideration from any Borrower for services in connection with this Agreement or otherwise without having to account for the same to Lenders.

     14.9. Delivery of Documents. To the extent Agent receives financial statements required under Sections 9.7, 9.8, 9.9, 9.13 and 9.14 or Borrowing Base Certificates from any Borrower pursuant to the terms of this Agreement which any Borrower is not obligated to deliver to each Lender, Agent will promptly furnish such documents and information to Lenders.

     14.10. Borrowers’ Undertaking to Agent. Without prejudice to their respective obligations to Lenders under the other provisions of this Agreement, each Borrower hereby undertakes with Agent to pay to Agent from time to time on demand all amounts from time to time due and payable by it for the account of Agent or Lenders or any of them pursuant to this Agreement to the extent not already paid. Any payment made pursuant to any such demand shall pro tanto satisfy the relevant Borrower’s obligations to make payments for the account of Lenders or the relevant one or more of them pursuant to this Agreement.

Amended & Restated Credit Agreement

     14.11. No Reliance on Agent’s Customer Identification Program. Each Lender acknowledges and agrees that neither such Lender, nor any of its Affiliates, participants or assignees, may rely on the Agent to carry out such Lender’s, Affiliate’s, participant’s or assignee’s customer identification program, or other obligations required or imposed under or pursuant to the USA PATRIOT Act or the regulations thereunder, including the regulations contained in 31 CFR 103.121 (as hereafter amended or replaced, the “CIP Regulations”), or any other Anti-Terrorism Law, including any programs involving any of the following items relating to or in connection with any Borrower, its Affiliates or its agents, this Agreement, the Other Documents or the transactions hereunder or contemplated hereby: (1) any identity verification procedures, (2) any record-keeping, (3) comparisons with government lists, (4) customer notices or (5) other procedures required under the CIP Regulations or such other laws.

     14.12. Other Agreements. Each of the Lenders agrees that it shall not, without the express consent of Agent, and that it shall, to the extent it is lawfully entitled to do so, upon the request of Agent, set off against the Obligations, any amounts owing by such Lender to any Borrower or any deposit accounts of any Borrower now or hereafter maintained with such Lender. Anything in this Agreement to the contrary notwithstanding, each of the Lenders further agrees that it shall not, unless specifically requested to do so by Agent, take any action to protect or enforce its rights arising out of this Agreement or the Other Documents, it being the intent of Lenders that any such action to protect or enforce rights under this Agreement and the Other Documents shall be taken in concert and at the direction or with the consent of Agent or Required Lenders.

XV BORROWING AGENCY.

     15.1. Borrowing Agency Provisions.

          (a) Each Borrower hereby irrevocably designates Borrowing Agent to be its attorney and agent and in such capacity to borrow, sign and endorse notes, and execute and deliver all instruments, documents, writings and further assurances now or hereafter required hereunder, on behalf of such Borrower or Borrowers, and hereby authorizes Agent to pay over or credit all loan proceeds hereunder in accordance with the request of Borrowing Agent.

          (b) The handling of this credit facility as a co-borrowing facility with a borrowing agent in the manner set forth in this Agreement is solely as an accommodation to Borrowers and at their request. Neither Agent nor any Lender shall incur liability to Borrowers as a result thereof. To induce Agent and Lenders to do so and in consideration thereof, each Borrower hereby indemnifies Agent and each Lender and holds Agent and each Lender harmless from and against any and all liabilities, expenses, losses, damages and claims of damage or injury asserted against Agent or any Lender by any Person arising from or incurred by reason of the handling of the financing arrangements of Borrowers as provided herein, reliance by Agent or any Lender on any request or instruction from Borrowing Agent or any other action taken by Agent or any Lender with respect to this Section 15.1 except due to willful misconduct or gross (not mere) negligence by the indemnified party (as determined by a court of competent jurisdiction in a final and non-appealable judgment).

Amended & Restated Credit Agreement

          (c) All Obligations shall be joint and several, and each Borrower shall make payment upon the maturity of the Obligations by acceleration or otherwise, and such obligation and liability on the part of each Borrower shall in no way be affected by any extensions, renewals and forbearance granted to Agent or any Lender to any Borrower, failure of Agent or any Lender to give any Borrower notice of borrowing or any other notice, any failure of Agent or any Lender to pursue or preserve its rights against any Borrower, the release by Agent or any Lender of any Collateral now or thereafter acquired from any Borrower, and such agreement by each Borrower to pay upon any notice issued pursuant thereto is unconditional and unaffected by prior recourse by Agent or any Lender to the other Borrowers or any Collateral for such Borrower’s Obligations or the lack thereof. Each Borrower waives all suretyship defenses.

     15.2. Waiver of Subrogation. Each Borrower expressly waives any and all rights of subrogation, reimbursement, indemnity, exoneration, contribution of any other claim which such Borrower may now or hereafter have against the other Borrowers or other Person directly or contingently liable for the Obligations hereunder, or against or with respect to the other Borrowers’ property (including, without limitation, any property which is Collateral for the Obligations), arising from the existence or performance of this Agreement, until termination of this Agreement and repayment in full of the Obligations.

XVI MISCELLANEOUS.

     16.1. Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of Texas applied to contracts to be performed wholly within the State of Texas.

Amended & Restated Credit Agreement

     16.2. Entire Understanding.

          (a) THIS AGREEMENT AND THE DOCUMENTS EXECUTED CONCURRENTLY HEREWITH CONTAIN THE ENTIRE UNDERSTANDING AMONG BORROWER, AGENT AND EACH LENDER AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES AND SUPERSEDES ALL PRIOR AGREEMENTS AND UNDERSTANDINGS, IF ANY, RELATING TO THE SUBJECT MATTER HEREOF. THERE ARE NO UNWRITTEN AGREEMENTS AMONG THE PARTIES. Any promises, representations, warranties or guarantees not herein contained and hereinafter made shall have no force and effect unless in writing, signed by each Borrower’s, Agent’s and each Lender’s respective officers. Neither this Agreement nor any portion or provisions hereof may be changed, modified, amended, waived, supplemented, discharged, cancelled or terminated orally or by any course of dealing, or in any manner other than by an agreement in writing, signed by the party to be charged. Each Borrower acknowledges that it has been advised by counsel in connection with the execution of this Agreement and Other Documents and is not relying upon oral representations or statements inconsistent with the terms and provisions of this Agreement.

          (b) The Required Lenders, Agent with the consent in writing of the Required Lenders, and Borrowers may, subject to the provisions of this Section 16.2 (b), from time to time enter into written supplemental agreements to this Agreement or the Other Documents executed by Borrowers, for the purpose of adding or deleting any provisions or otherwise changing, varying or waiving in any manner the rights of Lenders, Agent or Borrowers thereunder or the conditions, provisions or terms thereof of waiving any Event of Default thereunder, but only to the extent specified in such written agreements; provided, however, that no such supplemental agreement shall, without the consent of all Lenders:

               (i) increase the Commitment Percentage, the maximum dollar commitment of any Lender or the Maximum Loan Amount.

               (ii) extend the maturity of any Note or the due date for any amount payable hereunder, or decrease the rate of interest or reduce any fee payable by Borrowers to Lenders pursuant to this Agreement.

               (iii) alter the definition of the term Required Lenders or alter, amend or modify this Section 16.2(b).

               (iv) release any Collateral during any calendar year (other than in accordance with the provisions of this Agreement) having an aggregate value in excess of $1,000,000.

               (v) change the rights and duties of Agent.

               (vi) permit any Revolving Advance to be made if after giving effect thereto the total of Revolving Advances outstanding hereunder would exceed the Formula Amount for more than sixty (30) consecutive Business Days or exceed one hundred and five percent (105%) of the Formula Amount.

Amended & Restated Credit Agreement

               (vii) increase the Advance Rates above the Advance Rates in effect on the Restated Closing Date.

               (viii) release any Guarantor.

     Any such supplemental agreement shall apply equally to each Lender and shall be binding upon Borrowers, Lenders and Agent and all future holders of the Obligations. In the case of any waiver, Borrowers, Agent and Lenders shall be restored to their former positions and rights, and any Event of Default waived shall be deemed to be cured and not continuing, but no waiver of a specific Event of Default shall extend to any subsequent Event of Default (whether or not the subsequent Event of Default is the same as the Event of Default which was waived), or impair any right consequent thereon.

     In the event that Agent requests the consent of a Lender pursuant to this Section 16.2 and such Lender shall not respond or reply to Agent in writing within five (5) days of delivery of such request, such Lender shall be deemed to have consented to the matter that was the subject of the request. In the event that Agent requests the consent of a Lender pursuant to this Section 16.2 and such consent is denied, then PNC may, at its option, require such Lender to assign its interest in the Advances to PNC or to another Lender or to any other Person designated by the Agent (the “Designated Lender”), for a price equal to (i) the then outstanding principal amount thereof plus (ii) accrued and unpaid interest and fees (but not including any fees payable with respect to the termination of this Agreement before the expiration of the Term) then due such Lender, which interest and fees shall be paid when collected from Borrowers. In the event PNC elects to require any Lender to assign its interest to PNC or to the Designated Lender, PNC will so notify such Lender in writing within forty five (45) days following such Lender’s denial, and such Lender will assign its interest to PNC or the Designated Lender no later than five (5) days following receipt of such notice pursuant to a Commitment Transfer Supplement executed by such Lender, PNC or the Designated Lender, as appropriate, and Agent.

     Notwithstanding (a) the existence of a Default or an Event of Default, (b) that any of the other applicable conditions precedent set forth in Section 8.2 hereof have not been satisfied or (c) any other provision of this Agreement, Agent may at its discretion and without the consent of the Required Lenders, voluntarily permit the outstanding Revolving Advances at any time to exceed an amount equal to the Formula Amount by up to ten percent (10%) for up to thirty (30) consecutive Business Days (the “Out-of-Formula Loans”). If Agent is willing in its sole and absolute discretion to make such Out-of-Formula Loans, such Out-of-Formula Loans shall be payable on demand and shall bear interest at the Default Rate; provided that, if Lenders do make Out-of-Formula Loans, neither Agent nor Lenders shall be deemed thereby to have changed the limits of Section 2.1(a). For purposes of this paragraph, the discretion granted to Agent hereunder shall not preclude involuntary overadvances that may result from time to time due to the fact that the Formula Amount was unintentionally exceeded for any reason, including, but not limited to, Collateral previously deemed to be “Eligible Receivables,” becomes ineligible, collections of Receivables applied to reduce outstanding Revolving Advances are thereafter returned for insufficient funds or overadvances are made to protect or preserve the Collateral. In the event Agent involuntarily permits the outstanding Revolving Advances to exceed the Formula Amount by more than ten percent (10%), Agent shall use its efforts to have Borrowers decrease such excess in as expeditious a manner as is practicable under the circumstances and

Amended & Restated Credit Agreement

not inconsistent with the reason for such excess. Revolving Advances made after Agent has determined the existence of involuntary overadvances shall be deemed to be involuntary overadvances and shall be decreased in accordance with the preceding sentence.

     In addition to (and not in substitution of) the discretionary Revolving Advances permitted above in this Section 16.2, the Agent is hereby authorized by Borrowers and the Lenders, from time to time in the Agent’s sole discretion, (A) after the occurrence and during the continuation of a Default or an Event of Default, or (B) at any time that any of the other applicable conditions precedent set forth in Section 8.2 hereof have not been satisfied, to make Revolving Advances to Borrowers on behalf of the Lenders which the Agent, in its reasonable business judgment, deems necessary or desirable (a) to preserve or protect the Collateral, or any portion thereof, (b) to enhance the likelihood of, or maximize the amount of, repayment of the Advances and other Obligations, or (c) to pay any other amount chargeable to Borrowers pursuant to the terms of this Agreement; provided, that at any time after giving effect to any such Revolving Advances the outstanding Revolving Advances do not exceed one hundred and ten percent (110%) of the Formula Amount.

     16.3. Successors and Assigns; Participations; New Lenders.

          (a) This Agreement shall be binding upon and inure to the benefit of Borrowers, Agent, each Lender, all future holders of the Obligations and their respective successors and assigns, except that no Borrower may assign or transfer any of its rights or obligations under this Agreement without the prior written consent of Agent and each Lender.

          (b) Each Borrower acknowledges that in the regular course of commercial banking business one or more Lenders may at any time and from time to time sell participating interests in the Advances to other financial institutions (each such transferee or purchaser of a participating interest, a “Participant”). Each Participant may exercise all rights of payment (including rights of set-off) with respect to the portion of such Advances held by it or other Obligations payable hereunder as fully as if such Participant were the direct holder thereof provided that Borrowers shall not be required to pay to any Participant more than the amount which it would have been required to pay to Lender which granted an interest in its Advances or other Obligations payable hereunder to such Participant had such Lender retained such interest in the Advances hereunder or other Obligations payable hereunder and in no event shall Borrowers be required to pay any such amount arising from the same circumstances and with respect to the same Advances or other Obligations payable hereunder to both such Lender and such Participant. Each Borrower hereby grants to any Participant a continuing security interest in any deposits, moneys or other property actually or constructively held by such Participant as security for the Participant’s interest in the Advances.

          (c) Any Lender may, with the consent of Agent and the Borrowing Agent, on behalf of the Borrowers, which consent shall not be unreasonably withheld or delayed, sell, assign or transfer all or any part of its rights under this Agreement and the Other Documents to one or more additional banks or financial institutions and one or more additional banks or financial institutions may commit to make Advances hereunder (each a “Purchasing Lender”), in minimum amounts of not less than $5,000,000, pursuant to a Commitment Transfer Supplement, executed by a Purchasing Lender, the transferor Lender, and Agent and delivered to Agent for

Amended & Restated Credit Agreement

recording; provided, however, that if any Event of Default has occurred and is continuing, no consent by Borrowing Agent or Borrowers shall be required for such sale, assignment or transfer. Upon such execution, delivery, acceptance and recording, from and after the transfer effective date determined pursuant to such Commitment Transfer Supplement, (i) Purchasing Lender thereunder shall be a party hereto and, to the extent provided in such Commitment Transfer Supplement, have the rights and obligations of a Lender thereunder with a Commitment Percentage as set forth therein, and (ii) the transferor Lender thereunder shall, to the extent provided in such Commitment Transfer Supplement, be released from its obligations under this Agreement, the Commitment Transfer Supplement creating a novation for that purpose. Such Commitment Transfer Supplement shall be deemed to amend this Agreement to the extent, and only to the extent, necessary to reflect the addition of such Purchasing Lender and the resulting adjustment of the Commitment Percentages arising from the purchase by such Purchasing Lender of all or a portion of the rights and obligations of such transferor Lender under this Agreement and the Other Documents. Each Borrower hereby consents to the addition of such Purchasing Lender and the resulting adjustment of the Commitment Percentages arising from the purchase by such Purchasing Lender of all or a portion of the rights and obligations of such transferor Lender under this Agreement and the Other Documents. Borrowers shall execute and deliver such further documents and do such further acts and things in order to effectuate the foregoing.

          (d) Any Lender, with the consent of Agent and of Borrowing Agent, on behalf of the Borrowers, which consent shall not be unreasonably withheld or delayed, may directly or indirectly sell, assign or transfer all or any portion of its rights and obligations under or relating to Revolving Advances and/or CapEx Loans under this Agreement and the Other Documents to an entity, whether a corporation, partnership, trust, limited liability company or other entity that (i) is engaged in making, purchasing, holding or otherwise investing in bank loans and similar extensions of credit in the ordinary course of its business and (ii) is administered, serviced or managed by the assigning Lender or an Affiliate of such Lender (a “Purchasing CLO” and together with each Participant and Purchasing Lender, each a “Transferee” and collectively the “Transferees”), in minimum amounts of $5,000,000, pursuant to a Commitment Transfer Supplement modified as appropriate to reflect the interest being assigned (“Modified Commitment Transfer Supplement”), executed by any intermediate purchaser, the Purchasing CLO, the transferor Lender, and Agent as appropriate and delivered to Agent for recording; provided, however, that if any Event of Default has occurred and is continuing, no consent by Borrowing Agent or Borrowers shall be required for such sale, assignment or transfer. Upon such execution and delivery, from and after the transfer effective date determined pursuant to such Modified Commitment Transfer Supplement, (i) Purchasing CLO thereunder shall be a party hereto and, to the extent provided in such Modified Commitment Transfer Supplement, have the rights and obligations of a Lender thereunder and (ii) the transferor Lender thereunder shall, to the extent provided in such Modified Commitment Transfer Supplement, be released from its obligations under this Agreement, the Modified Commitment Transfer Supplement creating a novation for that purpose. Such Modified Commitment Transfer Supplement shall be deemed to amend this Agreement to the extent, and only to the extent, necessary to reflect the addition of such Purchasing CLO. Each Borrower hereby consents to the addition of such Purchasing CLO. Borrowers shall execute and deliver such further documents and do such further acts and things in order to effectuate the foregoing.

Amended & Restated Credit Agreement

          (e) Agent shall maintain at its address a copy of each Commitment Transfer Supplement and Modified Commitment Transfer Supplement delivered to it and a register (the “Register”) for the recordation of the names and addresses of each Lender and the outstanding principal, accrued and unpaid interest and other fees due hereunder. The entries in the Register shall be conclusive, in the absence of manifest error, and each Borrower, Agent and Lenders may treat each Person whose name is recorded in the Register as the owner of the Advance recorded therein for the purposes of this Agreement. The Register shall be available for inspection by Borrowers or any Lender at any reasonable time and from time to time upon reasonable prior notice. Agent shall receive a fee in the amount of $5,000 payable by the applicable Purchasing Lender and/or Purchasing CLO upon the effective date of each transfer or assignment (other than to an intermediate purchaser) to such Purchasing Lender and/or Purchasing CLO.

          (f) Each Borrower authorizes each Lender to disclose to any Transferee and any prospective Transferee any and all financial information in such Lender’s possession concerning such Borrower which has been delivered to such Lender by or on behalf of such Borrower pursuant to this Agreement or in connection with such Lender’s credit evaluation of such Borrower.

     16.4. Application of Payments. Agent shall have the continuing and exclusive right to apply or reverse and re-apply any payment and any and all proceeds of Collateral to any portion of the Obligations. To the extent that any Borrower makes a payment or Agent or any Lender receives any payment or proceeds of the Collateral for any Borrower’s benefit, which are subsequently invalidated, declared to be fraudulent or preferential, set aside or required to be repaid to a trustee, debtor in possession, receiver, custodian or any other party under any bankruptcy law, common law or equitable cause, then, to such extent, the Obligations or part thereof intended to be satisfied shall be revived and continue as if such payment or proceeds had not been received by Agent or such Lender.

     16.5. Indemnity. Each Borrower shall indemnify and defend Agent, each Lender and each of their respective officers, directors, Affiliates, attorneys, employees and agents from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses and disbursements of any kind or nature whatsoever (including fees and disbursements of counsel) which may be imposed on, incurred by, or asserted against Agent or any Lender in any claim, litigation, proceeding or investigation instituted or conducted by any Governmental Body or instrumentality or any other Person with respect to any aspect of, or any transaction contemplated by, or referred to in, or any matter related to, this Agreement or the Other Documents, whether or not Agent or any Lender is a party thereto, except to the extent that any of the foregoing arises out of the willful misconduct of the party being indemnified (as determined by a court of competent jurisdiction in a final and non-appealable judgment). WITHOUT LIMITING THE FOREGOING, (i) IT IS THE INTENTION OF BORROWERS, AND BORROWERS AGREE, THAT THE INDEMNITY PROVISIONS AND EXCULPATORY PROVISIONS CONTAINED IN THIS AGREEMENT SHALL APPLY WITH RESPECT TO LIABILITIES, OBLIGATIONS, LOSSES, DAMAGES, PENALTIES, ACTIONS, JUDGMENTS, SETTLEMENTS, SUITS, COSTS, EXPENSES AND DISBURSEMENTS OF ANY KIND WHATSOEVER (INCLUDING, WITHOUT LIMITATION, FEES AND DISBURSEMENTS OF COUNSEL), WHICH IN WHOLE OR IN PART ARE CAUSED BY OR ARISE OUT OF THE NEGLIGENCE OF ANY

Amended & Restated Credit Agreement

PARTY TO BE INDEMNIFIED, AND (ii) this indemnity shall extend to any liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses and disbursements of any kind or nature whatsoever (including fees and disbursements of counsel) asserted against or incurred by any of the indemnitees described above in this Section 16.5 by any Person under any Environmental Laws or similar laws by reason of any Borrower’s or any other Person’s failure to comply with laws applicable to solid or hazardous waste materials, including Hazardous Substances and Hazardous Waste, or other Toxic Substances. Additionally, if any taxes (excluding taxes imposed upon or measured solely by the net income of Agent and Lenders, but including any intangibles taxes, stamp tax, recording tax or franchise tax) shall be payable by Agent, Lenders or Borrowers on account of the execution or delivery of this Agreement, or the execution, delivery, issuance or recording of any of the Other Documents, or the creation or repayment of any of the Obligations hereunder, by reason of any Applicable Law now or hereafter in effect, Borrowers will pay (or will promptly reimburse Agent and Lenders for payment of) all such taxes, including interest and penalties thereon, and will indemnify and hold the indemnitees described above in this Section 16.5 harmless from and against all liability in connection therewith.

     16.7. Survival. The obligations of Borrowers under Sections 2.2(f), 3.7, 3.8, 3.9, 4.18(h), and 16.5 and the obligations of Lenders under Section 14.7, shall survive termination of this Agreement and the Other Documents and payment in full of the Obligations.

     16.8. Severability. If any part of this Agreement is contrary to, prohibited by, or deemed invalid under Applicable Laws or regulations, such provision shall be inapplicable and deemed omitted to the extent so contrary, prohibited or invalid, but the remainder hereof shall not be invalidated thereby and shall be given effect so far as possible.

     16.9. Expenses. All costs and expenses including, without limitation, all search, accounting, audit, appraisal, recording, professional and filing fees and expenses and reasonable attorneys’ fees (including the allocated costs of in-house counsel) and all other expenses and disbursements incurred by Agent on its behalf or on behalf of Lenders and Lenders (a) in all efforts made to enforce payment of any Obligation or effect collection of any Collateral, or (b) in connection with the entering into, documenting, negotiating, structuring, reviewing and closing this Agreement and the modification, amendment, administration, monitoring, and enforcement of this Agreement or any consents or waivers hereunder and all related agreements, documents and instruments, or (c) in instituting, monitoring, maintaining, preserving, enforcing and foreclosing on Agent’s security interest in or Lien on any of the Collateral, or monitoring, maintaining, preserving or enforcing any of Agent’s or any Lender’s rights hereunder and under all related agreements, documents and instruments, whether through judicial proceedings or otherwise, or (d) in defending or prosecuting any actions or proceedings arising out of or relating to Agent’s or any Lender’s transactions with any Borrower, or (e) in connection with any advice given to Agent or any Lender with respect to its rights and obligations under this Agreement and all related agreements, documents and instruments, may be charged to Borrowers’ Account and shall be part of the Obligations.

Amended & Restated Credit Agreement

threatens to fail to perform, observe or discharge such obligations or liabilities, any remedy at law may prove to be inadequate relief to Lenders; therefore, Agent, if Agent so requests, shall be entitled to temporary and permanent injunctive relief in any such case without the necessity of proving that actual damages are not an adequate remedy.

     16.11. Consequential Damages. Neither Agent nor any Lender, nor any agent or attorney for any of them, shall be liable to any Borrower or any Guarantor (or any Affiliate of any such Person) for indirect, punitive, exemplary or consequential damages arising from any breach of contract, tort or other wrong relating to the establishment, administration or collection of the Obligations or as a result of any transaction contemplated under this Agreement or any Other Document.

     16.12. Captions. The captions at various places in this Agreement are intended for convenience only and do not constitute and shall not be interpreted as part of this Agreement.

     16.13. Counterparts; Facsimile Signatures. This Agreement may be executed in any number of and by different parties hereto on separate counterparts, all of which, when so executed, shall be deemed an original, but all such counterparts shall constitute one and the same agreement. Any signature delivered by a party by facsimile transmission shall be deemed to be an original signature hereto.

     16.14. Construction. The parties acknowledge that each party and its counsel have reviewed this Agreement and that the normal rule of construction to the effect that any ambiguities are to be resolved against the drafting party shall not be employed in the interpretation of this Agreement or any amendments, schedules or exhibits thereto.

     16.15. Confidentiality; Sharing Information. Agent, each Lender and each Transferee shall hold all non-public information obtained by Agent, such Lender or such Transferee pursuant to the requirements of this Agreement in accordance with Agent’s, such Lender’s and such Transferee’s customary procedures for handling confidential information of this nature; provided, however, Agent, each Lender and each Transferee may disclose such confidential information (a) to its examiners, Affiliates, outside auditors, counsel and other professional advisors, (b) to Agent, any Lender or to any prospective Transferees, and (c) as required or requested by any Governmental Body or representative thereof or pursuant to legal process; provided, further that (i) unless specifically prohibited by Applicable Law or court order, Agent, each Lender and each Transferee shall use its reasonable best efforts prior to disclosure thereof, to notify the applicable Borrower of the applicable request for disclosure of such non-public information (A) by a Governmental Body or representative thereof (other than any such request in connection with an examination of the financial condition of a Lender or a Transferee by such Governmental Body) or (B) pursuant to legal process and (ii) in no event shall Agent, any Lender or any Transferee be obligated to return any materials furnished by any Borrower other than those documents and instruments in possession of Agent or any Lender in order to perfect its Lien on the Collateral once the Obligations have been paid in full and this Agreement has been terminated. Each Borrower acknowledges that from time to time financial advisory, investment banking and other services may be offered or provided to such Borrower or one or more of its Affiliates (in connection with this Agreement or otherwise) by any Lender or by one or more Subsidiaries or Affiliates of such Lender and each Borrower hereby authorizes each

Amended & Restated Credit Agreement

Lender to share any information delivered to such Lender by such Borrower and its Subsidiaries pursuant to this Agreement, or in connection with the decision of such Lender to enter into this Agreement, to any such Subsidiary or Affiliate of such Lender, it being understood that any such Subsidiary or Affiliate of any Lender receiving such information shall be bound by the provisions of this Section 16.15 as if it were a Lender hereunder. Such authorization shall survive the repayment of the other Obligations and the termination of this Agreement.

     16.16. Publicity. Each Borrower and each Lender hereby authorizes Agent to make appropriate announcements of the financial arrangement entered into among Borrowers, Agent and Lenders, including announcements which are commonly known as tombstones, in such publications and to such selected parties as Agent shall in its sole and absolute discretion deem appropriate.

     16.17. Non-Applicability of Chapter 346. Borrowers, Agent and each Lender hereby agree that, except for the opt-out provisions of Section 346.004 thereof, the provisions of Chapter 346 of the Texas Finance Code (regulating certain revolving credit loans and revolving tri-party accounts) shall not apply to this Agreement or any of the Other Documents.

     16.18. Certifications From Banks and Participants; US PATRIOT Act. Each Lender or assignee or participant of a Lender that is not incorporated under the Laws of the United States of America or a state thereof (and is not excepted from the certification requirement contained in Section 313 of the USA PATRIOT Act and the applicable regulations because it is both (i) an affiliate of a depository institution or foreign bank that maintains a physical presence in the United States or foreign country, and (ii) subject to supervision by a banking authority regulating such affiliated depository institution or foreign bank) shall deliver to the Agent the certification, or, if applicable, recertification, certifying that such Lender is not a “shell” and certifying to other matters as required by Section 313 of the USA PATRIOT Act and the applicable regulations: (1) within 10 days after the Restated Closing Date, and (2) as such other times as are required under the USA PATRIOT Act.

     16.19. Amendment and Restatement. This Agreement and the Notes are given in amendment, consolidation, restatement, renewal and extension (but not in novation, extinguishment or satisfaction) of the Original Agreement and the promissory notes issued in connection therewith. All Liens and security interests securing payment of the obligations under the Original Agreement and such promissory notes are hereby collectively renewed, extended, rearranged, ratified and brought forward as security for the payment and performance of the Obligations. With respect to matters relating to the period prior to the date hereof, all of the provisions of the Original Agreement (as amended hereby), and the security agreements and other documents, instruments or agreements executed in connection therewith, are each hereby ratified and confirmed and shall remain in force and effect. This Agreement shall not constitute a waiver by Agent and Lenders of any Default or Event of Default (each such term as defined in the Original Agreement) under the Original Agreement and the Loan Documents (as defined therein) that existed on or prior to the Restated Closing Date (and not otherwise expressly waived in writing by the Lenders (as defined in the Original Agreement)) immediately prior to the effectiveness hereof.
