Item 1.01 Entry into a Material Definitive Agreement

On February 20, 2007, Comfort Systems USA, Inc. (the “Company”) entered into an amended and restated senior credit facility (the “Facility”) arranged by Wachovia Bank, N.A. and provided by a syndicate of banks including Capital One, N.A. and Bank of Texas, N.A. The Facility is secured by substantially all of our assets except for assets related to projects subject to surety bonds. The Facility consists of a revolving credit facility that provides a $100 million line of credit to the Company. This line of credit replaces the Company’s prior credit facility, which was entered into on June 30, 2005.

The new Facility will expire in February 2012. The Facility contains only two financial covenants, which are:

Leverage Ratio — The Facility requires the ratio of the Company’s indebtedness less cash and cash equivalents to its Credit Facility Adjusted EBITDA not exceed 2.50.

Fixed Charge Coverage Ratio — The Facility requires that the ratio of Credit Facility Adjusted EBITDA, less non-financed capital expenditures, tax provision, dividends and amounts used to repurchase stock to the sum of interest expense and scheduled principal payments be at least 1.50. Capital expenditures, tax provision, dividends and stock repurchase payments are defined under the Facility for purposes of this covenant to be amounts for the four quarters ending as of any given quarterly covenant compliance measurement date. The calculation of the fixed charge coverage ratio was redefined to exclude acquisitions, stock repurchases and the payment of cash dividends, provided that the Leverage Ratio does not exceed 1.0.

Other Restrictions — The Facility permits acquisitions of up to $25 million per transaction, or $50 million in the aggregate. However, these limitations only apply when the Leverage Ratio is greater than 1.0.

The Company also issued a press release announcing the new Facility. A copy of the press release has been furnished as Exhibit 99.1 to this current report.

The foregoing description does not purport to be a complete statement of the parties’ rights and obligations under the Facility. The above description is qualified in its entirety by reference to the Facility, which is filed as Exhibit 10.1 to this current report.

Item 5.02 Departure of Directors or Principal Officers; Election of Directors; Appointment of Principal Officers

(b) In a letter dated February 26, 2007 addressed to the Company, Steven S. Harter resigned from the board of directors of the Company effective February 26, 2007. Prior to his resignation Mr. Harter served on the audit committee of the board of directors.

The amount of all Revolving Loans in any Borrowing must be greater than or equal to $100,000, or must equal the remaining availability under the Aggregate Commitment. The obligation of Borrower to repay to each Revolving Lender the aggregate amount of all Revolving Loans made by such Revolving Lender, together with interest accruing in connection therewith, shall be evidenced by one or more promissory notes made by Borrower payable to the order of such Revolving Lender in the principal amount of the Revolving Loan Commitment of the applicable Revolving Lender, substantially in the form of Exhibit 2.1 (each a “Revolving Note” and, collectively, the “Revolving Notes”). The amount of principal owing on any Revolving Note at any given time shall be the aggregate amount of all Revolving Loans theretofore made by such Revolving Lender minus all payments of principal theretofore received by such Revolving Lender on such Revolving Note. Interest on each Revolving Note shall accrue and be due and payable as provided herein. Each Revolving Note shall be due and payable as provided herein, and shall be due and payable in full on the Maturity Date. Subject to the terms and conditions hereof, Borrower may borrow, repay, and reborrow hereunder.

Section 2.2 Requests for Revolving Loans. Borrower must give to Agent written or electronic notice (or telephonic notice promptly confirmed in writing) of any requested Borrowing of new Revolving Loans to be advanced by Revolving Lenders. Each such notice constitutes a “Borrowing Notice” hereunder and must:

(a) specify (i) the aggregate amount of any such Borrowing of new Base Rate Loans and the date on which such Base Rate Loans are to be advanced, or (ii) the aggregate amount of any such Borrowing of new Eurodollar Loans, the date on which such Eurodollar Loans are to be advanced (which shall be the first day of the Interest Period which is to apply thereto), and the length of the applicable Interest Period; and

Each such telephonic request shall be deemed a representation, warranty, acknowledgment and agreement by Borrower as to the matters which are required to be set out in such written confirmation. Upon receipt of any such Borrowing Notice, Agent shall give each Lender prompt notice of the terms thereof. If all conditions precedent to such new Revolving Loans have been met, each Revolving Lender will on the date requested promptly remit to Agent at Agent’s office in Houston, Texas

the amount of such Revolving Lender’s new Revolving Loan in immediately available funds, and upon receipt of such funds, unless to its actual knowledge any conditions precedent to such Revolving Loans have been neither met nor waived as provided herein, Agent shall promptly make such Revolving Loans available to Borrower. Unless Agent shall have received prompt notice from a Revolving Lender that such Revolving Lender will not make available to Agent such Revolving Lender’s new Revolving Loan, Agent may in its discretion assume that such Revolving Lender has made such Revolving Loan available to Agent in accordance with this section and Agent may if it chooses, in reliance upon such assumption, make such Revolving Loan available to Borrower. If and to the extent such Revolving Lender shall not so make its new Revolving Loan available to Agent, such Revolving Lender and Borrower severally agree to pay or repay to Agent within three days after demand the amount of such Revolving Loan together with interest thereon, for each day from the date such amount was made available to Borrower until the date such amount is paid or repaid to Agent, with interest at (i) the Federal Funds Rate, if such Revolving Lender is making such payment and (ii) the interest rate applicable at the time to the other new Revolving Loans made on such date, if Borrower is making such repayment. If neither such Revolving Lender nor Borrower pays or repays to Agent such amount within such three-day period, Agent shall in addition to such amount be entitled to recover from such Revolving Lender and from Borrower, on demand, interest thereon at the Default Rate, calculated from the date such amount was made available to Borrower. The failure of any Revolving Lender to make any new Revolving Loan to be made by it hereunder shall not relieve any other Revolving Lender of its obligation hereunder, if any, to make its new Revolving Loan, but no Revolving Lender shall be responsible for the failure of any other Revolving Lender to make any new Revolving Loan to be made by such other Revolving Lender.

Section 2.3 Continuations and Conversions of Existing Loans. Borrower may make the following elections with respect to Loans already outstanding: to convert Base Rate Loans to Eurodollar Loans, to convert Eurodollar Loans to Base Rate Loans on the last day of the Interest Period applicable thereto, and to continue Eurodollar Loans beyond the expiration of such Interest Period by designating a new Interest Period to take effect at the time of such expiration. In making such elections, Borrower may combine existing Loans made pursuant to separate Borrowings into one new Borrowing or divide existing Loans made pursuant to one Borrowing into separate new Borrowings, provided that Borrower may have no more than five Borrowings of Eurodollar Loans outstanding at any time. To make any such election, Borrower must give to Agent written notice (or telephonic notice promptly confirmed in writing) of any such Conversion or Continuation of existing Loans, with a separate notice given for each new Borrowing. Each such notice constitutes a “Continuation/Conversion Notice” hereunder and must:

(a) specify the existing Loans which are to be Continued or Converted;

(b) specify (i) the aggregate amount of any Borrowing of Base Rate Loans into which such existing Loans are to be converted and the date on which such Continuation or Conversion is to occur, or (ii) the aggregate amount of any Borrowing of Eurodollar Loans into which such existing Loans are to be continued or converted, the date on which such Continuation or Conversion is to occur (which shall be the first day of the Interest Period which is to apply to such Eurodollar Loans), and the length of the applicable Interest Period; and

(c) be received by Agent not later than 11:00 a.m., Houston, Texas time, on (i) the day on which any such conversion to Base Rate Loans is to occur, or (ii) the third Business Day preceding the day on which any such Continuation or Conversion to Eurodollar Loans is to occur.

Each such written request or confirmation must be made in the form and substance of the “Continuation/Conversion Notice” attached hereto as Exhibit 2.3(c), duly completed. Each such telephonic request shall be deemed a representation, warranty, acknowledgment and agreement by Borrower as to the matters which are required to be set out in such written confirmation. Upon receipt of any such Continuation/Conversion Notice, Agent shall give each Lender prompt notice of the terms thereof. Each Continuation/Conversion Notice shall be irrevocable and binding on Borrower. During the continuance of any Default, Borrower may not make any election to convert existing Loans into Eurodollar Loans or continue existing Loans as Eurodollar Loans. If (due to the existence of a Default or for any other reason) Borrower fails to timely and properly give any Continuation/Conversion Notice with respect to a Borrowing of existing Eurodollar Loans at least three days prior to the end of the Interest Period applicable thereto, such Eurodollar Loans shall automatically be converted into Base Rate Loans at the end of such Interest Period. No new funds shall be repaid by Borrower or advanced by any Lender in connection with any Continuation or Conversion of existing Loans pursuant to this section, and no such Continuation or Conversion shall be deemed to be a new advance of funds for any purpose; such Continuations and Conversions merely constitute a change in the interest rate applicable to already outstanding Loans.

Section 2.4 Use of Proceeds. Borrower shall use the Loans to (i) refinance Prior Indebtedness under the Prior Credit Documents; (ii) refinance Matured LC Obligations; and (iii) provide working capital for its operations and for other general business purposes. Borrower shall use all Letters of Credit for its general corporate purposes. In no event shall the funds from any Loan or any Letter of Credit be used directly or indirectly by any Person for personal, family, household or agricultural purposes or for the purpose, whether immediate, incidental or ultimate, of purchasing, acquiring or carrying any Margin Stock or to extend credit to others directly or indirectly for the purpose of purchasing or carrying any such Margin Stock. Borrower represents and warrants that Borrower is not engaged principally, or as one of Borrower’s important activities, in the business of extending credit to others for the purpose of purchasing or carrying such Margin Stock.

Section 2.5 Interest Rates and Fees; Payment Dates. (a) Interest. Subject to subsection (b) below, (i) each Base Rate Loan shall bear interest on each day it is outstanding at the Adjusted Base Rate in effect on such day, and (ii) each Eurodollar Loan shall bear interest on each day during the related Interest Period at the related Adjusted Eurodollar Rate in effect on such day, and (iii) if an Event of Default has occurred and is continuing, all Loans shall bear interest on each day outstanding at the applicable Default Rate. Past due payments of principal and interest shall bear interest at the rates and in the manner set forth in the Notes. Notwithstanding the forgoing, Borrower may request from time to time that Borrower and the Lender enter into a Hedging Contract providing for interest rate protection (1) for a term expiring no earlier than one year after the Closing Date; and (2) with other terms and conditions reasonably satisfactory to Agent.

(b) Default Rate. If an Event of Default shall have occurred and be continuing under Section 8.1(a), (b), (k)(i), (k)(ii), and (k)(iii) all outstanding Loans shall bear interest at the applicable Default Rate. In addition, if an Event of Default shall have occurred and be continuing (other than under Section 8.1(a), (b), (k)(i), (k)(ii) or (k)(iii)), Required Lenders may, by notice to Borrower, elect to have the outstanding Loans bear interest at the applicable Default Rate, whereupon such Loans shall bear interest at the applicable Default Rate until the earlier of (i) the first date thereafter upon which there shall be no Event of Default continuing and (ii) the date upon which Required Lenders shall have rescinded such notice.

(c) Commitment Fees. In consideration of each Revolving Loan Commitment of each Revolving Lender to make Revolving Loans, Borrower will pay to Agent for the account of each Revolving Lender a fee (the “Commitment Fee”) determined on a daily basis by multiplying the applicable Commitment Fee Rate by the Percentage Share of such Revolving Lender of the unused portion of the Revolving Loan Commitment on each day during the Commitment Period, determined for each such day by deducting from the amount of the Revolving Loan Commitment at the end of such day the Revolving Facility Usage. This Commitment Fee shall be due and payable in arrears on the first day of each Fiscal Quarter and at the end of the Commitment Period.

(d) Upfront Fees. In consideration of the Lenders’ commitment to make Loans, Borrower will pay to Agent for the ratable account of the Lenders an upfront fee in the aggregate amount of $150,000, due and payable on the date hereof.

(e) Additional Fees. In addition to all other amounts due to Agent under the Loan Documents, Borrower will pay fees to the Lead Arranger as described in a letter agreement of even date herewith between Lead Arranger and Borrower.

(f) Payment Dates. On each Interest Payment Date relating to Base Rate Loans, Borrower shall pay to the Lenders all unpaid interest which has accrued on the Base Rate Loans to but not including such Interest Payment Date. On each Interest Payment Date relating to a Eurodollar Loan, Borrower shall pay to Lenders all unpaid interest which has accrued on such Eurodollar Loan to but not including such Interest Payment Date.

Section 2.6 Optional Prepayments and Voluntary Reduction of Commitment.. Borrower may, without penalty, (a) upon notice to Agent to be received no later than 11:00 a.m., Houston, Texas time, with respect to any Base Rate Loan and (b) upon three Business Days’ notice to each Lender with respect to any Eurodollar Loan, from time to time and without premium or penalty prepay the Loans, in whole or in part, provided (i) that the aggregate amounts of all partial prepayments of principal on the Notes equals $100,000 or any higher integral multiple of $100,000; and (ii) that if Borrower prepays any Eurodollar Loan on any day other than the last day of the Interest Period applicable thereto, it shall pay to Lenders any amounts due under Section 3.5. Each prepayment of principal of any Eurodollar Loan under this section shall be accompanied by all interest then accrued and unpaid on the principal so prepaid. Any principal or interest prepaid pursuant to this section shall be in addition to, and not in lieu of, all payments otherwise required to be paid under the Loan Documents at the time of such prepayment.

Section 2.7 Mandatory Prepayments. (a) If at any time the Revolving Facility Usage exceeds the Revolving Loan Commitment (whether due to a reduction in the Revolving Loan Commitment in accordance with this Agreement, or otherwise), Borrower shall immediately upon demand prepay the principal of the Loans (and after the Loans are repaid in full, provide LC Collateral in accordance with Section 2.14(b)) in an amount at least equal to such excess.

(b) Intentionally Left Blank.

(c) No later than the 366th day after the receipt of any Net Casualty Proceeds aggregating in excess of $2,000,000 for any single transaction or related series of transactions, Borrower shall apply such Net Casualty Proceeds to repay the Revolving Loans, and the Revolving Loan Commitment shall be permanently reduced in an aggregate amount equal to such Net Casualty Proceeds.

(d) Each prepayment of principal under this section shall be accompanied by all interest then accrued and unpaid on the principal so prepaid. Any principal or interest prepaid pursuant to this section shall be in addition to, and not in lieu of, all payments otherwise required to be paid under the Loan Documents at the time of such prepayment.

Section 2.8 Intentionally Left Blank.

Section 2.9 Letters of Credit. Subject to the terms and conditions hereof, Borrower may during the Commitment Period request LC Issuer to, and LC Issuer shall, issue one or more Letters of Credit, provided that, after taking such Letter of Credit into account:

(a) the Revolving Facility Usage does not exceed the Aggregate Commitment (whether due to a reduction in the Aggregate Commitment in accordance with this Agreement, or otherwise) at such time; and

(b) the expiration date of such Letter of Credit is prior to the end of the Commitment Period.

All Existing Letters of Credit shall be deemed to have been issued pursuant hereto, and from and after the Closing Date shall be subject to and governed by the terms and conditions hereof.

Section 2.10 Requesting Letters of Credit. Borrower must make written application for any Letter of Credit at least two (2) Business Days (or such shorter period as LC Issuer may in its discretion from time to time agree) before the date on which Borrower desires for LC Issuer to issue such Letter of Credit. By making any such written application Borrower shall be deemed to have represented and warranted that the LC Conditions described in Section 2.11 will be met as of the date of issuance of such Letter of Credit. Each such written application for a Letter of Credit must be made in writing in the form and substance of Exhibit 2.10, the terms and provisions of which are hereby incorporated herein by reference (or in such other form as may mutually be agreed upon by LC Issuer and Borrower). Two (2) Business Days after the LC Conditions for a Letter of Credit have been met (or if LC Issuer otherwise desires to issue such Letter of Credit), LC Issuer will issue such Letter of Credit at LC Issuer’s office in Houston, Texas. If any provisions of any LC Application conflict with any provisions of this Agreement, the provisions of this Agreement shall govern and control. Borrower shall promptly examine a

copy of each Letter of Credit and each amendment thereto that is delivered to it and, in the event of any claim of noncompliance with Borrower’s instructions or other irregularity, Borrower will promptly notify LC Issuer.

Section 2.11 Reimbursement and Participations. (a) Reimbursement by Borrower. Each Matured LC Obligation shall constitute a Revolving Loan by LC Issuer to Borrower. Borrower promises to pay to LC Issuer, or to LC Issuer’s order, on the Business Day immediately following the day on which a demand is made, the full amount of each Matured LC Obligation, together with interest thereon at the Default Rate applicable to Base Rate Loans. The obligation of Borrower to reimburse LC Issuer for each Matured LC Obligation shall be absolute, unconditional and irrevocable, and shall be paid strictly in accordance with the terms of this Agreement (including any LC Application) under all circumstances, including the following: (i) any lack of validity or enforceability of such Letter of Credit or any other agreement or instrument relating thereto; (ii) the existence of any claim, counterclaim, set-off, defense or other right that Borrower may have at any time against any beneficiary or any transferee of such Letter of Credit (or any Person for whom any such beneficiary or any such transferee may be acting), LC Issuer or any other Person, whether in connection with this Agreement, the transactions contemplated hereby or by such Letter of Credit or any agreement or instrument relating thereto, or any unrelated transaction; (iii) any draft, demand, certificate or other document presented under such Letter of Credit proving to be forged, fraudulent, invalid or insufficient in any respect or any statement therein being untrue or inaccurate in any respect; or any loss or delay in the transmission or otherwise of any document required in order to make a drawing under such Letter of Credit; (iv) any payment by LC Issuer under such Letter of Credit against presentation of a draft or certificate that does not strictly comply with the terms of such Letter of Credit; or (v) any other circumstance or happening whatsoever, whether or not similar to any of the foregoing. Without limiting the generality of the foregoing, it is expressly agreed that the absolute and unconditional nature of Borrower’s obligations under this section to reimburse LC Issuer for each drawing under a Letter of Credit will not be excused by the gross negligence or willful misconduct of LC Issuer. However, the foregoing shall not be construed to excuse LC Issuer from liability to Borrower to the extent of any direct damages (as opposed to consequential damages, claims in respect of which are hereby waived by Borrower to the extent permitted by applicable Law) suffered by Borrower that are caused by LC Issuer’s gross negligence or willful misconduct in determining whether drafts and other documents presented under a Letter of Credit comply with the terms thereof.

(b) Letter of Credit Advances. If the beneficiary of any Letter of Credit makes a draft or other demand for payment thereunder then Borrower may, during the interval between the making thereof and the honoring thereof by LC Issuer, request Lenders to make Loans to Borrower in the amount of such draft or demand, which Loans shall be made concurrently with LC Issuer’s payment of such draft or demand and shall be immediately used by LC Issuer to repay the amount of the resulting Matured LC Obligation. Such a request by Borrower shall be made in compliance with all of the provisions hereof, provided that for the purposes of the first sentence of Section 2.1(b), the amount of such Loans shall be considered, but the amount of the Matured LC Obligation to be concurrently paid by such Loans shall not be considered.

(c) Participation by Lenders. LC Issuer irrevocably agrees to grant and hereby grants to each Lender, and to induce LC Issuer to issue Letters of Credit hereunder each Lender

irrevocably agrees to accept and purchase and hereby accepts and purchases from LC Issuer, on the terms and conditions hereinafter stated and for such Lender’s own account and risk, an undivided interest equal to such Lender’s Percentage Share of LC Issuer’s obligations and rights under each Letter of Credit issued hereunder and the amount of each Matured LC Obligation paid by LC Issuer thereunder. Each Lender unconditionally and irrevocably agrees with LC Issuer that, if a Matured LC Obligation is paid under any Letter of Credit for which LC Issuer is not reimbursed in full by Borrower in accordance with the terms of this Agreement and the related LC Application (including any reimbursement by means of concurrent Loans or by the application of LC Collateral), such Lender shall (in all circumstances and without set-off or counterclaim) pay to LC Issuer on demand, in immediately available funds at LC Issuer’s address for notices hereunder, such Lender’s Percentage Share of such Matured LC Obligation (or any portion thereof which has not been reimbursed by Borrower). Each Lender’s obligation to pay LC Issuer pursuant to the terms of this subsection is irrevocable and unconditional. If any amount required to be paid by any Lender to LC Issuer pursuant to this subsection is paid by such Lender to LC Issuer within three Business Days after the date such payment is due, LC Issuer shall in addition to such amount be entitled to recover from such Lender, on demand, interest thereon calculated from such due date at the Federal Funds Rate. If any amount required to be paid by any Lender to LC Issuer pursuant to this subsection is not paid by such Lender to LC Issuer within three Business Days after the date such payment is due, LC Issuer shall in addition to such amount be entitled to recover from such Lender, on demand, interest thereon calculated from such due date at the Default Rate.

(d) Distributions to Participants. Whenever LC Issuer has in accordance with this section received from any Lender payment of such Lender’s Percentage Share of any Matured LC Obligation, if LC Issuer thereafter receives any payment of such Matured LC Obligation or any payment of interest thereon (whether directly from Borrower or by application of LC Collateral or otherwise, and excluding only interest for any period prior to LC Issuer’s demand that such Lender make such payment of its Percentage Share), LC Issuer will distribute to such Lender its Percentage Share of the amounts so received by LC Issuer; provided, however, that if any such payment received by LC Issuer must thereafter be returned by LC Issuer, such Lender shall return to LC Issuer the portion thereof which LC Issuer has previously distributed to it.

(e) Calculations. A written advice setting forth in reasonable detail the amounts owing under this section, submitted by LC Issuer to Borrower or any Lender from time to time, shall be conclusive, absent manifest error, as to the amounts thereof.

Section 2.12 Letter of Credit Fees. In consideration of LC Issuer’s issuance of any Letter of Credit, Borrower agrees to pay (a) to Agent, for the account of all Lenders in accordance with their respective Percentage Shares, a per annum letter of credit issuance fee at a rate equal to 75% of the Eurodollar Margin in effect for Revolving Loans, and (b) to such LC Issuer for its own account, a letter of credit fronting fee at a rate equal to 0.125% per annum. The letter of credit fee and the letter of credit fronting fee will be calculated on the undrawn face amount of each Letter of Credit outstanding on each day at the above-applicable rates and will be due and payable in arrears on the first day of each Fiscal Quarter and at the end of the Commitment Period.

Section 2.13 No Duty to Inquire. (a) Drafts and Demands. LC Issuer is authorized and instructed to accept and pay drafts and demands for payment under any Letter of Credit without requiring, and without responsibility for, any determination as to the existence of any event giving rise to said draft, either at the time of acceptance or payment or thereafter. LC Issuer is under no duty to determine the proper identity of anyone presenting such a draft or making such a demand (whether by tested telex or otherwise) as the officer, representative or Agent of any beneficiary under any Letter of Credit, and payment by LC Issuer to any such beneficiary when requested by any such purported officer, representative or Agent is hereby authorized and approved. Borrower releases each Lender Party from, and agrees to hold each Lender Party harmless and indemnified against, any liability or claim in connection with or arising out of the subject matter of this section, which indemnity shall apply whether or not any such liability or claim is in any way or to any extent caused, in whole or in part, by any negligent act or omission of any kind by any Lender Party, provided only that no Lender Party shall be entitled to indemnification for that portion, if any, of any liability or claim which is proximately caused by its own individual gross negligence or willful misconduct, as determined in a final judgment.

(b) Extension of Maturity. If the maturity of any Letter of Credit is extended by its terms or by Law or governmental action, if any extension of the maturity or time for presentation of drafts or any other modification of the terms of any Letter of Credit is made at the request of any Restricted Person, or if the amount of any Letter of Credit is increased at the request of any Restricted Person, this Agreement shall be binding upon all Restricted Persons with respect to such Letter of Credit as so extended, increased or otherwise modified, with respect to drafts and property covered thereby, and with respect to any action taken by LC Issuer, LC Issuer’s correspondents, or any Lender Party in accordance with such extension, increase or other modification.

(c) Transferees of Letters of Credit. If any Letter of Credit provides that it is transferable, LC Issuer shall have no duty to determine the proper identity of anyone appearing as transferee of such Letter of Credit, nor shall LC Issuer be charged with responsibility of any nature or character for the validity or correctness of any transfer or successive transfers, and payment by LC Issuer to any purported transferee or transferees as determined by LC Issuer is hereby authorized and approved, and Borrower releases each Lender Party from, and agrees to hold each Lender Party harmless and indemnified against, any liability or claim in connection with or arising out of the foregoing, which indemnity shall apply whether or not any such liability or claim is in any way or to any extent caused, in whole or in part, by any negligent act or omission of any kind by any Lender Party, provided only that no Lender Party shall be entitled to indemnification for that portion, if any, of any liability or claim which is proximately caused by its own individual gross negligence or willful misconduct, as determined in a final judgment.

Section 2.14 LC Collateral. (a) Intentionally Left Blank.

(b) Acceleration of LC Obligations. If the Obligations or any part thereof become immediately due and payable pursuant to Section 8.1 then, unless Required Lenders otherwise specifically elect to the contrary (which election may thereafter be retracted by Required Lenders at any time), all LC Obligations shall be deemed to become immediately due and payable without regard to whether or not actual drawings or payments on the Letters of Credit have occurred, and Borrower shall be obligated to pay to LC Issuer immediately an amount equal to

the aggregate LC Obligations which are then outstanding, which amount shall be held by LC Issuer as security for LC Obligations (the “LC Collateral”) and the other Obligations, and such LC Collateral may be applied from time to time to any Matured LC Obligations or any other Obligations which are due and payable.

(c) Investment of LC Collateral. Pending application thereof, all LC Collateral shall be invested by the Agent in such Investments as the Agent may choose in its sole discretion. All interest on (and other proceeds of) such Investments shall be reinvested or applied to Matured LC Obligations or other Obligations which are due and payable. When all Obligations have been satisfied in full, including all LC Obligations, all Letters of Credit have expired or been terminated, and all of Borrower’s reimbursement obligations in connection therewith have been satisfied in full or when the condition pursuant to which the LC Collateral was required no longer exists, the Agent shall release any remaining LC Collateral. Borrower hereby assigns and grants to the Agent a continuing security interest in all LC Collateral paid by it to the Agent, all Investments purchased with such LC Collateral, and all proceeds thereof to secure its Matured LC Obligations and its Obligations under this Agreement, each Note, and the other Loan Documents, and Borrower agrees that such LC Collateral, Investments and proceeds shall be subject to all of the terms and conditions of the Security Documents. Borrower further agrees that the Agent shall have all of the rights and remedies of a secured party under the Uniform Commercial Code as adopted in the State of Texas with respect to such security interest and that an Event of Default under this Agreement shall constitute a default for purposes of such security interest.

(d) Payment of LC Collateral. When Borrower is required to provide LC Collateral for any reason and fails to do so on the day when required, the Agent or LC Issuer may without notice to Borrower or any other Restricted Person provide such LC Collateral (whether by application of proceeds of other Collateral, by transfers from other accounts maintained with the Agent or LC Issuer, or otherwise) using any available funds of Borrower or any other Person also liable to make such payments. Any such amounts which are required to be provided as LC Collateral and which are not provided on the date required shall, for purposes of each Security Document, be considered past due Obligations owing hereunder, and LC Issuer is hereby authorized to exercise its respective rights under each Security Document to obtain such amounts.

Section 2.15 Existing Letters of Credit. On the effective date of this Agreement, without further action by any party hereto, (x) the applicable LC Issuer for each Existing Letter of Credit shall be deemed to have granted to each Lender, and each Lender shall be deemed to have acquired from the LC Issuer, a participation in each of the Existing Letters of Credit equal to such Lender’s Percentage Share of (A) the aggregate amount available to be drawn under such Existing Letters of Credit and (B) the aggregate amount of any outstanding reimbursement obligations in respect thereof. With respect to each of the Existing Letters of Credit (i) if the applicable LC Issuer has heretofore sold a participation therein to a Lender, the applicable LC Issuer and such Lender agree that such participation shall be automatically canceled on the effective date of this Agreement and (ii) if the applicable LC Issuer has heretofore sold a participation therein to any bank or financial institution that is not a Lender, then the applicable LC Issuer shall procure the termination of such participation on or prior to the effective date of this Agreement. On and after the effective date of this Agreement, each of the Existing Letters

of Credit shall be a Letter of Credit issued hereunder. Further, with respect to that certain Existing Letter of Credit issued by Prior Agent on January 14, 2004 in the amount of $20,287,414.00 for the benefit of American Zurich Insurance Co., Borrower shall use commercially reasonable efforts to replace such Existing Letter of Credit with a Letter of Credit issued by Wachovia Bank, N.A., as LC Issuer, on or before the expiration of sixty (60) days immediately following the effective date of this Agreement.

ARTICLE III
PAYMENTS TO LENDERS

Section 3.1 General Procedures. Borrower will make each payment which it owes under the Loan Documents to Agent for the account of the Lender Party to whom such payment is owed, in lawful money of the United States of America, without set-off, deduction or counterclaim, and in immediately available funds. Each such payment must be received by Agent not later than 11:00 a.m., Houston, Texas time, on the date such payment becomes due and payable. Any payment received by Agent after such time will be deemed to have been made on the next following Business Day. Should any such payment become due and payable on a day other than a Business Day, the maturity of such payment shall be extended to the next succeeding Business Day, and, in the case of a payment of principal or past due interest, interest shall accrue and be payable thereon for the period of such extension as provided in the Loan Document under which such payment is due. Each payment under a Loan Document shall be due and payable at the place set forth for Agent on Schedule 3.1 hereto. When Agent collects or receives money on account of the Obligations, Agent shall distribute all money so collected or received, and each Lender Party shall apply all such money so distributed, as follows (except as otherwise provided in Section 8.3):

(a) first, for the payment of all Obligations which are then due (and if such money is insufficient to pay all such Obligations, first to any reimbursements due Agent under Section 6.9 or 10.4 and then to the partial payment of all other Obligations then due in proportion to the amounts thereof, or as Lender Parties shall otherwise agree);

(b) then for the prepayment of amounts owing under the Loan Documents (other than principal of the Loans) if so specified by Borrower;

(c) then for the prepayment of principal of the Loans, together with accrued and unpaid interest on the principal so prepaid; and

(d) last, for the payment or prepayment of any other Obligations.

All payments applied to principal or interest on any Note shall be applied first to any interest then due and payable, then to principal then due and payable, and last to any prepayment of principal and interest in compliance with Sections 2.6 and 2.7. All distributions of amounts described in any of subsections (b), (c) or (d) above shall be made by Agent pro rata to each Lender Party then owed Obligations described in such subsection in proportion to all amounts owed to all Lender Parties which are described in such subsection; provided that if any Lender then owes payments to LC Issuer for the purchase of a participation under Section 2.13(c) or to Agent under Section 9.9, any amounts otherwise distributable under this section to such Lender shall be deemed to belong to LC Issuer, or Agent, respectively, to the extent of such unpaid payments, and Agent shall apply such amounts to make such unpaid payments rather than distribute such amounts to such Lender.

Section 3.2 Capital Reimbursement. If either (a) the introduction or implementation after the date hereof of or the compliance with or any change after the date hereof in or in the interpretation of any Law regarding capital adequacy, or (b) the introduction or implementation

after the date hereof of or the compliance with any request, directive or guideline issued after the date hereof from any central bank or other governmental authority (whether or not having the force of Law) regarding capital requirements has or would have the effect of reducing the rate of return on any Lender Party’s capital, or on the capital of any corporation controlling such Lender Party, as a consequence of the Loans made, or Letters of Credit issued, by such Lender Party, to a level below that which such Lender Party or such corporation could have achieved but for such change (taking into consideration such Lender Party’s policies and the policies of any such corporation with respect to capital adequacy), then from time to time Borrower will pay to Agent for the benefit of such Lender Party, within five (5) Business Days of demand therefore by such Lender Party, such additional amount or amounts which such Lender Party shall determine to be appropriate to compensate such Lender Party for such reduction.

Section 3.3 Increased Cost of Eurodollar Loans or Letters of Credit. (a) If any change after the date hereof in any applicable Law (whether now in effect or hereinafter enacted or promulgated, including Regulation D) or any interpretation or administration thereof by any governmental authority charged with the interpretation or administration thereof (whether or not having the force of Law):

(i) shall change the basis of taxation of payments to any Lender Party of any principal, interest, or other amounts attributable to any Eurodollar Loan or Letter of Credit or otherwise due under this Agreement in respect of any Eurodollar Loan or Letter of Credit (other than Reimbursable Taxes governed by Section 3.6 and taxes imposed on or measured by its overall net income, and franchise taxes imposed on it (in lieu of net income taxes), by the jurisdiction (or any political subdivision thereof) under the Laws of which it is organized or otherwise resides for tax purposes or maintains any Applicable Lending Office); or

(ii) shall change, impose, modify, apply or deem applicable any reserve, special deposit or similar requirements in respect of any Eurodollar Loan made by any Lender Party or any Letter of Credit (excluding any reserve requirement included in the computation of the Adjusted Eurodollar Rate) or against assets of, deposits with or for the account of, or credit extended by, such Lender Party; or

(iii) shall impose on any Lender Party or the interbank eurocurrency deposit market any condition affecting any Eurodollar Loan or Letter of Credit,

the result of which is to increase the cost to any Lender Party of agreeing to make or making, funding or maintaining Eurodollar Loans or (as the case may be) issuing or participating in Letters of Credit, or a reduction in the amount received or receivable by such Lender in connection with any of the foregoing, then such Lender Party shall promptly notify Agent and Borrower in writing of the happening of such event and of the amount required to compensate such Lender Party for such additional costs or reduced return (on an after-tax basis, taking into account any taxes on and deductions, credits or other tax benefits in respect of such compensation), whereupon (i) Borrower shall pay such amount to Agent for the account of such Lender Party and (ii) Borrower may elect, by giving to Agent and such Lender Party not less than three Business Days’ notice, to convert all (but not less than all) of any such Eurodollar Loans of such Lender Party into Base Rate Loans.

(b) A certificate of a Lender Party setting forth the amount or amounts necessary to compensate such Lender Party or the corporation controlling such Lender Party, as the case may be, as specified in Section 3.2 or this Section 3.3 shall be delivered to Borrower and shall be conclusive absent manifest error. Borrower shall pay the applicable Lender Party the amount shown as due on any such certificate within 3 Business Days after receipt thereof.

(c) Failure or delay on the part of any Lender Party to demand compensation pursuant to Section 3.2 or this Section 3.3 shall not constitute a waiver of such Lender Party’s right to demand such compensation.

Section 3.4 Illegality. If any change after the date hereof in applicable Laws, or in the interpretation or administration thereof of or in any jurisdiction whatsoever, domestic or foreign, shall make it unlawful for any Lender Party to fund or maintain Eurodollar Loans, then, upon notice by such Lender Party to Borrower and Agent, (a) Borrower’s right to elect Eurodollar Loans from such Lender Party shall be suspended to the extent and for the duration of such illegality, (b) all Eurodollar Loans of such Lender Party which are then the subject of any Borrowing Notice and which cannot be lawfully funded shall be funded as Base Rate Loans of such Lender Party, and (c) all Eurodollar Loans of such Lender Party shall be converted automatically to Base Rate Loans on the respective last days of the then current Interest Periods with respect to such Loans or within such earlier period as required by Law. If any such conversion of a Eurodollar Loan occurs on a day which is not the last day of the then current Interest Period with respect thereto, Borrower shall pay to such Lender Party such amounts, if any, as may be required pursuant to Section 3.5.

Section 3.5 Funding Losses. In addition to its other obligations hereunder, Borrower will indemnify each Lender Party against, and reimburse each Lender Party on demand for, any loss or expense incurred or sustained by such Lender Party (including any loss or expense incurred by reason of the liquidation or reemployment of deposits or other funds acquired by a Lender Party to fund or maintain Eurodollar Loans but excluding any loss of Base Rate Margin or Eurodollar Margin), as a result of (a) any payment or prepayment (whether authorized or required hereunder or otherwise) of all or a portion of a Eurodollar Loan on a day other than the day on which the applicable Interest Period ends, (b) any payment or prepayment, whether required hereunder or otherwise, of a Loan made after the delivery, but before the effective date, of a Continuation/Conversion Notice requesting the continuation of outstanding Eurodollar Loans as, or the conversion of outstanding Base Rate Loans to, Eurodollar Loans, if such payment or prepayment prevents such Continuation/Conversion Notice from becoming fully effective, (c) the failure of any Loan to be made or of any Continuation/Conversion Notice requesting the continuation of outstanding Eurodollar Loans as, or the conversion of outstanding Base Rate Loans to, Eurodollar Loans to become effective due to any condition precedent not being satisfied or due to any other action or inaction of any Restricted Person, (d) any Conversion (whether authorized or required hereunder or otherwise) of all or any portion of any Eurodollar Loan into a Base Rate Loan or into a different Eurodollar Loan on a day other than the day on which the applicable Interest Period ends, or (e) any assignment of a Eurodollar Loan on a day other than the last day of the Interest Period therefor as a result of a request by Borrower pursuant to Section 3.8(b).

Section 3.6 Reimbursable Taxes. Borrower covenants and agrees that:

(a) Borrower will indemnify each Lender Party against and reimburse each Lender Party for all present and future income, stamp and other taxes, levies, costs and charges whatsoever imposed, assessed, levied or collected on or in respect of this Agreement or any Eurodollar Loans or Letters of Credit (whether or not legally or correctly imposed, assessed, levied or collected), excluding, however, (i) taxes imposed on or measured by its overall net income, and franchise taxes imposed on it (in lieu of net income taxes), by the jurisdiction (or any political subdivision thereof) under the Laws of which it is organized or otherwise resides for tax purposes or maintains any Applicable Lending Office, (ii) with respect to each Lender Party, taxes imposed by reason of any present or former connection between such Lender Party and the jurisdiction imposing such taxes, other than solely as a result of this Agreement or any Note or any transaction contemplated hereby, and (iii) any United States withholding tax imposed on any payment by Borrower pursuant to this Agreement or under any Eurodollar Loans or Letters of Credit, but not excluding any portion of such tax that exceeds the United States withholding tax which would have been imposed on such a payment to such Lender Party under the laws and treaties in effect when such Lender Party first becomes a party to this Agreement (all such non-excluded taxes, levies, costs and charges being collectively called “Reimbursable Taxes”). Such indemnification shall be on an after-tax basis and, except as otherwise provided in Section 3.6(b), paid within 3 Business Days after a Lender Party makes demand therefor.

(b) All payments on account of the principal of, and interest on, each Lender Party’s Loans and Note, and all other amounts payable by Borrower to any Lender Party hereunder, shall be made in full without set-off or counterclaim and shall be made free and clear of and without deductions or withholdings of any nature by reason of any Reimbursable Taxes, all of which will be for the account of Borrower. In the event of Borrower being compelled by Law to make any such deduction or withholding from any payment to any Lender Party, Borrower shall pay on the due date of such payment, by way of additional interest, such additional amounts as are needed to cause the amount receivable by such Lender Party after such deduction or withholding to equal the amount which would have been receivable in the absence of such deduction or withholding. If Borrower should make any deduction or withholding as aforesaid, Borrower shall within 60 days thereafter forward to such Lender Party an official receipt or other official document evidencing payment of such deduction or withholding.

(c) If Borrower is ever required to pay any Reimbursable Tax with respect to any Eurodollar Loan, Borrower may elect, by giving to Agent and such Lender Party not less than three Business Days’ notice, to convert all (but not less than all) of any such Eurodollar Loan into a Base Rate Loan, but such election shall not diminish Borrower’s obligation to pay all Reimbursable Taxes.

(d) Notwithstanding the foregoing provisions of this section, Borrower shall be entitled, to the extent it is required to do so by Law, to deduct or withhold (and not to make any indemnification or reimbursement for) income or other similar taxes imposed by the United States of America from interest, fees or other amounts payable hereunder for the account of any Lender Party, other than a Lender Party (i) who is a U.S. person for Federal income tax purposes or (ii) who has the Prescribed Forms on file with Agent (with copies provided to Borrower) for the applicable year to the extent deduction or withholding of such taxes is not required as a result

of the filing of such Prescribed Forms, provided that if Borrower shall so deduct or withhold any such taxes, it shall provide a statement to Agent and such Lender Party, setting forth the amount of such taxes so deducted or withheld, the applicable rate and any other information or documentation which such Lender Party may reasonably request for assisting such Lender Party to obtain any allowable credits or deductions for the taxes so deducted or withheld in the jurisdiction or jurisdictions in which such Lender Party is subject to tax. As used in this section, “Prescribed Forms” means such duly executed forms or statements, and in such number of copies, which may, from time to time, be prescribed by Law and which, pursuant to applicable provisions of (x) an income tax treaty between the United States and the country of residence of the Lender Party providing the forms or statements, (y) the Internal Revenue Code, or (z) any applicable rules or regulations thereunder, permit Borrower to make payments hereunder for the account of such Lender Party free of such deduction or withholding of income or similar taxes.

Section 3.7 Alternative Rate of Interest. If prior to the commencement of any Interest Period for a Borrowing of Eurodollar Loans:

(a) Agent determines that adequate and reasonable means do not exist for ascertaining the Eurodollar Rate for such Interest Period (any such determination shall be conclusive absent manifest error); or

(b) Agent is advised by Required Lenders that the Eurodollar Rate for such Interest Period will not adequately and fairly reflect the cost to such Lenders of making or maintaining their Loans included in such Borrowing for such Interest Period;

then Agent shall give notice thereof to Borrower and Lenders by telephone or telecopy as promptly as practicable thereafter and, until Agent notifies Borrower and Lenders that the circumstances giving rise to such notice no longer exist, (i) any Continuation/Conversion Notice that requests the conversion of any Borrowing to, or continuation of any Borrowing as, a Borrowing of Eurodollar Loans shall be ineffective and shall be deemed a request to continue such Borrowing as a Borrowing of Base Rate Loans and (ii) if any Borrowing Notice requests a Borrowing of Eurodollar Loans, such Borrowing shall be made as a Borrowing of Base Rate Loans. Upon receipt of such notice, Borrower may revoke any pending request for a Borrowing of, conversion to or continuation of Eurodollar Loans.

Section 3.8 Change of Applicable Lending Office; Replacement of Lenders.

(a) Each Lender Party agrees that, upon the occurrence of any event giving rise to the operation of Sections 3.2, 3.3, 3.4 or 3.6 with respect to such Lender Party, it will, if requested by Borrower, use reasonable efforts (subject to overall policy considerations of such Lender Party) to designate another Applicable Lending Office, provided that such designation is made on such terms that such Lender Party and its Applicable Lending Office suffer no economic, legal or regulatory disadvantage, with the object of avoiding the consequence of the event giving rise to the operation of any such section. Nothing in this section shall affect or postpone any of the obligations of Borrower or the rights of any Lender Party provided in Sections 3.2, 3.3, 3.4, or 3.6.

(b) If any Lender requests compensation under Section 3.2 or 3.3, or if Borrower is required to pay any additional amount to any Lender Party or any governmental authority for the account of any Lender Party pursuant to Section 3.6, or if the obligation of any Lender Party to make or maintain Loans as, or convert Loans to, Eurodollar Loans is suspended pursuant to Section 3.4, or if any Lender Party defaults in its obligation to fund Loans hereunder, then Borrower may, at its sole expense and effort (such expense to include any transfer fee payable to Agent under Section 10.5(c) and any expense pursuant to Article III), upon notice to such Lender Party and Agent, require such Lender Party to assign and delegate in whole (but not in part), without recourse (in accordance with and subject to the restrictions contained in Section 10.5), all its interests, rights and obligations under this Agreement to an Eligible Transferee that shall assume such obligations (which Eligible Transferee may be another Lender Party, if a Lender Party accepts such assignment); provided that (i) Borrower shall have received the prior written consent of Agent, which consent shall not unreasonably be withheld, (ii) such Lender Party shall have received payment of an amount equal to the outstanding principal of its Loans, accrued interest thereon, accrued fees and all other amounts payable to it hereunder from Borrower or such Eligible Transferee (including any amounts payable pursuant to Section 3.5), (iii) in the case of any such assignment resulting from a claim for compensation under Section 3.2 or 3.3 or payments required to be made pursuant to Section 3.6, such assignment will result in a reduction in such compensation or payments, and (iv) if the Borrower elects to exercise such right with respect to any Lender Party, it shall be obligated to replace all Lender Parties that have made similar requests. A Lender Party shall not be required to make any such assignment and delegation if, prior thereto, as a result of a waiver by such Lender Party or otherwise, the circumstances entitling Borrower to require such assignment and delegation cease to apply. Any Lender Party being replaced shall execute and deliver an Assignment and Acceptance with respect to such Lender Party’s outstanding Loans and participations in LC Obligations.

a Material Adverse Change; and (e) no Restricted Person otherwise has any known material contingent liability under any Environmental Laws or in connection with the release into the environment, or the storage or disposal, of any Hazardous Materials which could reasonably be expected to cause a Material Adverse Change. Each Restricted Person undertook, at the time of its acquisition of each of its material properties, all appropriate inquiry into the previous ownership and uses of the Property and any potential environmental liabilities associated therewith.

Borrower owns, directly or indirectly, the equity interests in each of its Subsidiaries indicated in Section 5.14 of the Disclosure Schedule or as disclosed to Agent in writing.

Section 5.15 Government Regulation. Neither Borrower nor any other Restricted Person owing Obligations is (a) a “registered holding company”, or a “subsidiary company” of a “registered holding company”, or an “affiliate” of a “registered holding company” within the meaning of the Public Utility Holding Company Act of 1935, as amended; or (b) an “investment company” or a company “controlled” by an “investment company” within the meaning of the Investment Company Act of 1940, as amended. The pledge of the Equity of each Subsidiary of Borrower does not violate Regulation T, U, or X of the Board of Governors of the Federal Reserve System.

Section 5.16 Insider. No Restricted Person, nor, to the knowledge of Borrower as of the Closing Date, any Person having “control” (as that term is defined in 12 U.S.C. § 375b(9) or in regulations promulgated pursuant thereto) of any Restricted Person, is a “director” or an “executive officer” or “principal shareholder” (as those terms are defined in 12 U.S.C. § 375b(8) or (9) or in regulations promulgated pursuant thereto) of any Lender, of a bank holding company of which any Lender is a Subsidiary or of any Subsidiary of a bank holding company of which any Lender is a Subsidiary.

Section 5.17 Solvency. Upon giving effect to the issuance of the Notes, the execution of the Loan Documents by Borrower and each Guarantor and the consummation of the transactions contemplated hereby, Borrower and the Guarantors, on a Consolidated basis, will be Solvent. Neither Borrower nor any Restricted Person has incurred (whether under the Loan Documents or otherwise), nor does any Restricted Person intend to incur or believe that it will incur Liabilities which will be beyond its ability to pay as such debts mature.

Section 5.18 Tax Shelter Regulations. Borrower does not intend to treat the Loans and/or Letters of Credit and related transactions as being a “reportable transaction” (within the meaning of Treasury Regulation Section 1.6011-4). In the event Borrower determines to take any action inconsistent with such intention, it will promptly notify Agent thereof. If Borrower so notifies Agent, Borrower acknowledges that one or more of the Lenders may treat its Loans and/or Letters of Credit as part of a transaction that is subject to Treasury Regulation Section 301.6112-1, and such Lender or Lenders, as applicable, will maintain the lists and other records required by such Treasury Regulation.

Each Restricted Person has good and defensible title to all of the Collateral and to all of its material properties and assets, free and clear of all Liens, encumbrances, or adverse claims other than Permitted Liens and free and clear of all impediments to the use of such properties and assets in such Restricted Person’s business. Each Restricted Person possesses all licenses, permits, franchises, patents, copyrights, trademarks and trade names, and other intellectual property (or otherwise possesses the right to use such intellectual property without violation of the rights of any other Person) which are necessary to carry out its business as presently conducted and as presently proposed to be conducted hereafter, which could reasonably be expected to cause a Material Adverse Change and no Restricted Person is in violation of the terms under which it possesses such intellectual property or the right to use such intellectual property, the violation of which could reasonably be expected to cause a Material Adverse Change.

Section 5.20 Regulation U. None of the Borrower and its Subsidiaries are engaged in the business of extending credit for the purpose of purchasing or carrying Margin Stock, and no proceeds of any Loans will be used for a purpose which violates Regulation U.

Agent may accept deposits from, lend money to, act as trustee under indentures of, and generally engage in any kind of business with any Restricted Person or their Affiliates, all as if it were not Agent hereunder and without any duty to account therefor to any other Lender.

Section 9.6 Sharing of Set-Offs and Other Payments. Each Lender Party agrees that if it shall, whether through the exercise of rights under Security Documents or rights of banker’s lien, set off, or counterclaim against Borrower or otherwise, obtain payment of a portion of the aggregate Obligations owed to it which, taking into account all distributions made by Agent

under Section 3.1, causes such Lender Party to have received more than it would have received had such payment been received by Agent and distributed pursuant to Section 3.1, then (a) it shall be deemed to have simultaneously purchased and shall be obligated to purchase interests in the Obligations as necessary to cause all Lender Parties to share all payments as provided for in Section 3.1, and (b) such other adjustments shall be made from time to time as shall be equitable to ensure that Agent and all Lender Parties share all payments of Obligations as provided in Section 3.1; provided, however, that nothing herein contained shall in any way affect the right of any Lender Party to obtain payment (whether by exercise of rights of banker’s lien, set-off or counterclaim or otherwise) of indebtedness other than the Obligations. Borrower expressly consents to the foregoing arrangements and agrees that any holder of any such interest or other participation in the Obligations, whether or not acquired pursuant to the foregoing arrangements, may to the fullest extent permitted by Law exercise any and all rights of banker’s lien, set-off, or counterclaim as fully as if such holder were a holder of the Obligations in the amount of such interest or other participation. If all or any part of any funds transferred pursuant to this section is thereafter recovered from the seller under this section which received the same, the purchase provided for in this section shall be deemed to have been rescinded to the extent of such recovery, together with interest, if any, if interest is required pursuant to the order of a Tribunal order to be paid on account of the possession of such funds prior to such recovery.

Section 9.7 Investments. Whenever Agent in good faith determines that it is uncertain about how to distribute to Lender Parties any funds which it has received, or whenever Agent in good faith determines that there is any dispute among Lender Parties about how such funds should be distributed, Agent may choose to defer distribution of the funds which are the subject of such uncertainty or dispute. If Agent in good faith believes that the uncertainty or dispute will not be promptly resolved, or if Agent is otherwise required to invest funds pending distribution to Lender Parties, Agent shall invest such funds pending distribution; all interest on any such Investment shall be distributed upon the distribution of such Investment and in the same proportion and to the same Persons as such Investment. All monies received by Agent for distribution to Lender Parties (other than to the Person who is Agent in its separate capacity as a Lender Party) shall be held by Agent pending such distribution solely as Agent for such Lender Parties, and Agent shall have no equitable title to any portion thereof.

Section 9.8 Benefit of Article IX. The provisions of this Article (other than the following Section 9.9) are intended solely for the benefit of Lender Parties, and no Restricted Person shall be entitled to rely on any such provision or assert any such provision in a claim or defense against any Lender. Lender Parties may waive or amend such provisions as they desire without any notice to or consent of Borrower or any Restricted Person.

Section 9.9 Resignation. Agent may resign at any time by giving written notice thereof to Lenders and Borrower. Each such notice shall set forth the date of such resignation. Upon any such resignation, Required Lenders shall have the right to appoint (with, unless an Event of Default shall have occurred and be continuing, the consent of Borrower, such consent not to be unreasonably withheld or delayed) a successor Agent. A successor must be appointed for any retiring Agent, and such Agent’s resignation shall become effective when such successor accepts such appointment. If, within thirty days after the date of the retiring Agent’s resignation, no successor Agent has been appointed and has accepted such appointment, then the retiring Agent may appoint (with, unless an Event of Default shall have occurred and be continuing, the

consent of Borrower, such consent not to be unreasonably withheld or delayed) a successor Agent, which shall be a commercial bank organized or licensed to conduct a banking or trust business under the Laws of the United States of America or of any state thereof. Upon the acceptance of any appointment as Agent hereunder by a successor Agent, the retiring Agent shall be discharged from its duties and obligations under this Agreement and the other Loan Documents. After any retiring Agent’s resignation hereunder the provisions of this Article IX shall continue to inure to its benefit as to any actions taken or omitted to be taken by it while it was Agent under the Loan Documents.

Section 9.10 Notice of Default. Agent shall not be deemed to have knowledge or notice of the occurrence of any Default, except with respect to defaults in the payment of principal, interest and fees required to be paid to Agent for the account of Lenders, unless Agent shall have received written notice from a Lender or Borrower referring to this Agreement, describing such Default and stating that such notice is a “notice of default.” Agent will notify Lenders of its receipt of any such notice. Agent shall take such action with respect to such Default as may be directed by Required Lenders in accordance with Article VIII; provided, however, that unless and until Agent has received any such direction, Agent may (but shall not be obligated to) take such action, or refrain from taking such action, with respect to such Default as it shall deem advisable or in the best interest of Lenders.

Section 9.11 Co-Agents. The Parties identified on the facing page of this Agreement as “Lead Arranger” or “Co-Agent” have no right, power, obligation, liability, responsibility, or duty under the Loan Documents in such capacity. Without limiting the foregoing, each Party so identified as “Lead Arranger” and “Co-Agent” shall not have and shall not be deemed to have any fiduciary relationship with any other Lender. Each Lender acknowledges that it has not relied, and will not rely, on taking or not taking action hereunder.

Section 10.1 Waivers and Amendments; Acknowledgments.

(a) Waivers and Amendments. No failure or delay (whether by course of conduct or otherwise) by any Lender in exercising any right, power or remedy which such Lender Party may have under any of the Loan Documents shall operate as a waiver thereof or of any other right, power or remedy, nor shall any single or partial exercise by any Lender Party of any such right, power or remedy preclude any other or further exercise thereof or of any other right, power or remedy. No waiver of any provision of any Loan Document and no consent to any departure therefrom shall ever be effective unless it is in writing and signed as provided below in this section, and then such waiver or consent shall be effective only in the specific instances and for the purposes for which given and to the extent specified in such writing. No notice to or demand on any Restricted Person shall in any case of itself entitle any Restricted Person to any other or further notice or demand in similar or other circumstances. This Agreement and the other Loan Documents set forth the entire understanding between the parties hereto with respect to the transactions contemplated herein and therein and supersede all prior discussions and understandings with respect to the subject matter hereof and thereof, and no waiver, consent, release, modification or amendment of or supplement to this Agreement or the other Loan Documents shall be valid or effective against any party hereto unless the same is in writing and signed by (i) if such party is Borrower, by Borrower, (ii) if such party is Agent or LC Issuer, by such party, and (iii) if such party is a Lender, by such Lender or by Agent on behalf of Lenders with the written consent of Required Lenders (which consent has already been given as to the termination of the Loan Documents as provided in Section 10.9). Notwithstanding the foregoing or anything to the contrary herein, Agent shall not, without the prior consent of each individual Lender, execute and deliver on behalf of such Lender any waiver or amendment which would: (1) waive any of the conditions specified in Article IV (provided that Agent may in its discretion withdraw any request it has made under Section 4.2), (2) increase the maximum amount which such Lender is committed hereunder to lend, (3) reduce any fees payable to such Lender hereunder, or the principal of, or interest on, either of such Lender’s Notes, (4) extend the Maturity Date, or postpone any date fixed for any payment of any such fees, principal or interest, (5) amend the definition herein of “Required Lenders” or otherwise change the aggregate amount of Percentage Shares which is required for Agent, Lenders or any of them to take any particular action under the Loan Documents, (6) release Borrower from its obligation to pay such Lender’s Obligations or any Guarantor (other than a Guarantor which ceases to be a Subsidiary pursuant to a sale or other disposition permitted by the Loan Documents) from its guaranty of such payment or (7) release all or substantially all of the any Collateral, except for such releases relating to sales or dispositions of property permitted by the Loan Documents, or (8) amend this Section 10.1(a). Notwithstanding the foregoing or anything to the contrary herein, Agent shall not, without the prior consent of each individual Lender affected thereby (or, as applicable, an Affiliate of such Lender), execute and deliver any waiver or amendment to any Loan Document which would (i) cause an obligation under any outstanding Hedging Contract owing to such Lender (or its Affiliate) that, prior to such waiver or amendment, constituted a “Lender Hedging Obligation” to cease to be a “Lender Hedging Obligation” or (ii) cause the priority of the Lien securing such obligation or the priority of payment with respect to such obligation in connection with the exercise of remedies under such Loan Document to be subordinate in any manner to the

Obligations (other than expense reimbursements, expenses of enforcement, and other similar obligations owing under the Loan Documents).

(b) Acknowledgments and Admissions. Borrower hereby represents, warrants, acknowledges and admits that (i) it has been advised by counsel in the negotiation, execution and delivery of the Loan Documents to which it is a party, (ii) it has made an independent decision to enter into this Agreement and the other Loan Documents to which it is a party, without reliance on any representation, warranty, covenant or undertaking by Agent or any Lender, whether written, oral or implicit, other than as expressly set out in this Agreement or in another Loan Document delivered on or after the date hereof, (iii) there are no representations, warranties, covenants, undertakings or agreements by any Lender as to the Loan Documents except as expressly set out in this Agreement or in another Loan Document delivered on or after the date hereof, (iv) no Lender has any fiduciary obligation toward Borrower with respect to any Loan Document or the transactions contemplated thereby, (v) the relationship pursuant to the Loan Documents between Borrower and the other Restricted Persons, on one hand, and each Lender, on the other hand, is and shall be solely that of debtor and creditor, respectively, provided that, solely for purposes of Section 10.5(f), Agent shall act as Agent of Borrower in maintaining the Register as set forth therein, (vi) no partnership or joint venture exists with respect to the Loan Documents between any Restricted Person and any Lender, (vii) Agent is not Borrower’s Agent, but Agent for Lenders, provided that, solely for purposes of Section 10.5(f), Agent shall act as Agent of Borrower in maintaining the Register as set forth therein, (viii) should an Event of Default or Default occur or exist, each Lender will determine in its sole discretion and for its own reasons what remedies and actions it will or will not exercise or take at that time subject to the terms of this Agreement, (ix) without limiting any of the foregoing, Borrower is not relying upon any representation or covenant by any Lender, or any representative thereof, and no such representation or covenant has been made, that any Lender will, at the time of an Event of Default or Default, or at any other time, waive, negotiate, discuss, or take or refrain from taking any action permitted under the Loan Documents with respect to any such Event of Default or Default or any other provision of the Loan Documents, and (x) all Lender Parties have relied upon the truthfulness of the acknowledgments in this section in deciding to execute and deliver this Agreement and to become obligated hereunder.

(c) Joint Acknowledgment. THIS WRITTEN AGREEMENT AND THE OTHER LOAN DOCUMENTS REPRESENT THE FINAL AGREEMENT BETWEEN THE PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES.

THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES.

Section 10.2 Survival of Agreements; Cumulative Nature. Except for representations and warranties given as of a specified date, all of Restricted Persons’ various representations, warranties, covenants and agreements in the Loan Documents shall survive the execution and delivery of this Agreement and the other Loan Documents and the performance hereof and thereof, including the making or granting of the Loans and the delivery of the Notes and the other Loan Documents, and shall further survive until all of the Obligations are paid in full to each Lender Party and all of Lender Parties’ obligations to Borrower are terminated. All statements and agreements contained in any certificate or other instrument delivered by any

Restricted Person to any Lender Party under any Loan Document shall be deemed representations and warranties by Borrower or agreements and covenants of Borrower under this Agreement. The representations, warranties, indemnities, and covenants made by Restricted Persons in the Loan Documents, and the rights, powers, and privileges granted to Lender Parties in the Loan Documents, are cumulative, and, except for expressly specified waivers and consents, no Loan Document shall be construed in the context of another to diminish, nullify, or otherwise reduce the benefit to any Lender Party of any such representation, warranty, indemnity, covenant, right, power or privilege. In particular and without limitation, no exception set out in this Agreement to any representation, warranty, indemnity, or covenant herein contained shall apply to any similar representation, warranty, indemnity, or covenant contained in any other Loan Document, unless the Loan Documents shall expressly provide that such exception shall apply to such similar representation, warranty, indemnity, or covenant.

Section 10.3 Notices. All notices, requests, consents, demands and other communications required or permitted under any Loan Document shall be in writing, unless otherwise specifically provided in such Loan Document (provided that Agent may give telephonic notices to the other Lender Parties), and shall be deemed sufficiently given or furnished if delivered by personal delivery, by facsimile or other electronic transmission, by delivery service with proof of delivery, or by registered or certified United States mail, postage prepaid, to Borrower and Restricted Persons at the address of Borrower specified on the signature pages hereto and to each Lender Party at its address specified on Schedule 3.1 hereto (unless changed by similar notice in writing given by the particular Person whose address is to be changed). Any such notice or communication shall be deemed to have been given (a) in the case of personal delivery or delivery service, as of the date of first attempted delivery during normal business hours at the address provided herein, (b) in the case of facsimile or other electronic transmission, upon receipt, or (c) in the case of registered or certified United States mail, three days after deposit in the mail; provided, however, that no Borrowing Notice shall become effective until actually received by Agent.

Section 10.4 Payment of Expenses; Indemnity.

(a) Payment of Expenses. Whether or not the transactions contemplated by this Agreement are consummated, Borrower will promptly (and in any event, within thirty (30) days after any invoice or other statement or notice) pay: (i) all transfer, stamp, mortgage, documentary or other similar taxes, assessments or charges levied by any governmental or revenue authority in respect of this Agreement or any of the other Loan Documents or any other document or transaction referred to herein or therein, (ii) all reasonable costs and expenses incurred by or on behalf of Agent (including without limitation reasonable attorneys’ fees, travel costs and miscellaneous expenses), but excluding consultants fees other than in connection with an annual field audit permitted below, in connection with (1) the negotiation, preparation, execution and delivery of the Loan Documents, and any and all consents, waivers or other documents or instruments relating thereto, (2) the filing, recording, refiling and re-recording of any Loan Documents and any other documents or instruments or further assurances required to be filed or recorded or refiled or re-recorded by the terms of any Loan Document, (3) the borrowings hereunder and other action reasonably required in the course of administration hereof, (4) monitoring or confirming (or preparation or negotiation of any document related to) any Restricted Person’s compliance with any covenants or conditions contained in this Agreement or

in any Loan Document, and (iii) all reasonable costs and expenses incurred by the Agent on behalf of any Lender Party (including without limitation reasonable attorneys’ fees, reasonable consultants’ fees and reasonable accounting fees) in connection with the conduct of an annual field audit, the preservation of any rights under the Loan Documents or the defense or enforcement of any of the Loan Documents (including this section), any attempt to cure any breach thereunder by any Restricted Person, or the defense of any Lender Party’s exercise of its rights thereunder. In addition to the foregoing, until all Obligations have been paid in full, Borrower will also pay or reimburse Agent for all reasonable out-of-pocket costs and expenses of Agent or its agents or employees in connection with the continuing administration of the Loans and the related due diligence of Agent, including travel and miscellaneous expenses and reasonable fees and expenses of Agent’s outside counsel and consultants engaged in connection with the Loan Documents.

(b) Indemnity. Borrower agrees to indemnify each Lender Party, upon demand, from and against any and all liabilities, obligations, broker’s fees, claims, losses, damages, penalties, fines, actions, judgments, suits, settlements, costs, expenses or disbursements (including reasonable fees of attorneys, accountants, experts and advisors) of any kind or nature whatsoever (in this section collectively called “liabilities and costs”) which to any extent (in whole or in part) may be imposed on, incurred by, or asserted against such Lender Party growing out of, resulting from or in any other way associated with any of the Collateral, the Loan Documents and the transactions and events (including the enforcement or defense thereof) at any time associated therewith or contemplated therein (whether arising in contract or in tort or otherwise). Among other things, the foregoing indemnification covers all liabilities and costs incurred by any Lender Party related to any breach of a Loan Document by a Restricted Person, any bodily injury to any Person or damage to any Person’s property, or any violation or noncompliance with any Environmental Laws by any Lender Party or any other Person or any liabilities or duties of any Lender Party or any other Person with respect to Hazardous Materials found in or released into the environment.

THE FOREGOING INDEMNIFICATION SHALL APPLY WHETHER OR NOT SUCH LIABILITIES AND COSTS ARE IN ANY WAY OR TO ANY EXTENT OWED, IN WHOLE OR IN PART, UNDER ANY CLAIM OR THEORY OF STRICT LIABILITY OR CAUSED, IN WHOLE OR IN PART BY ANY NEGLIGENT ACT OR OMISSION OF ANY KIND BY ANY LENDER PARTY,

provided only that no Lender Party shall be entitled under this section to receive indemnification for that portion, if any, of any liabilities and costs which is proximately caused by its own individual gross negligence or willful misconduct, as determined in a final judgment. If any Person (including Borrower or any of its Affiliates) ever alleges such gross negligence or willful misconduct by any Lender Party, the indemnification provided for in this section shall nonetheless be paid upon demand, subject to later adjustment or reimbursement, until such time as a court of competent jurisdiction enters a final judgment as to the extent and effect of the alleged gross negligence or willful misconduct. As used in this section the term “Lender Party” shall refer not only to each Person designated as such in Section 1.1 but also to each director, officer, Agent, trustee, attorney, employee, representative and Affiliate of or for such Person.

Section 10.5 Joint and Several Liability; Parties in Interest; Assignments.

(a) All Obligations which are incurred by two or more Restricted Persons shall be their joint and several obligations and liabilities. All grants, covenants and agreements contained in the Loan Documents shall bind and inure to the benefit of the parties thereto and their respective successors and assigns; provided, however, that no Restricted Person may assign or transfer any of its rights or delegate any of its duties or obligations under any Loan Document without the prior consent of the Required Lenders. Neither Borrower nor any Affiliates of Borrower shall directly or indirectly purchase or otherwise retire any Obligations owed to any Lender nor will any Lender accept any offer to do so, unless each Lender shall have received substantially the same offer with respect to the same Percentage Share of the Obligations owed to it. If Borrower or any Affiliate of Borrower at any time purchases some but less than all of the Obligations owed to all Lender Parties, such purchaser shall not be entitled to any rights of any Lender under the Loan Documents unless and until Borrower or its Affiliates have purchased all of the Obligations.

(b) No Lender shall sell any participation interest in its commitment hereunder or any of its rights under its Loans or under the Loan Documents to any Person unless the agreement between such Lender and such participant at all times provides: (i) that such participation exists only as a result of the agreement between such participant and such Lender and that such transfer does not give such participant any right to vote as a Lender or any other direct claims or rights against any Person other than such Lender, (ii) that such participant is not entitled to payment from any Restricted Person under Sections 3.2 through 3.8 of amounts in excess of those payable to such Lender under such sections (determined without regard to the sale of such participation), and (iii) unless such participant is an Affiliate of such Lender, that such participant shall not be entitled to require such Lender to take any action under any Loan Document or to obtain the consent of such participant prior to taking any action under any Loan Document, except for actions which would require the consent of all Lenders under subsection (a) of Section 10.1. No Lender selling such a participation shall, as between the other parties hereto and such Lender, be relieved of any of its obligations hereunder as a result of the sale of such participation. Each Lender which sells any such participation to any Person (other than an Affiliate of such Lender) shall give prompt notice thereof to Agent and Borrower.

(c) Except for sales of participations under the immediately preceding subsection, no Lender shall make any assignment or transfer of any kind of its commitments or any of its rights under its Loans or under the Loan Documents, except for assignments to an Eligible Transferee, and then only if such assignment is made in accordance with the following requirements:

(i) Each such assignment shall apply to all Obligations owing to the assignor Lender hereunder and to the unused portion of the assignor Lender’s Revolving Loan Commitment, so that after such assignment is made the assignor Lender shall have a fixed (and not a varying) Percentage Share in its Loans and Notes and be committed to make that Percentage Share of all future Loans, the assignee shall have a fixed Percentage Share in the aggregate Loans and Notes and be committed to make that Percentage Share of all future Loans, and, except in the case of an assignment of the entire remaining amount of the assignor’s Percentage Share of the Revolving Loan

Commitment, the Revolving Loan Commitment of both the assignor and assignee, after giving effect to such assignment, shall equal or exceed $2,500,000.

(ii) The parties to each such assignment shall execute and deliver to Agent, for its acceptance and recording in the “Register” (as defined below in this section), an Assignment and Acceptance in the form of Exhibit 10.5, appropriately completed, together with the Note subject to such assignment and a processing fee payable to Agent of $3,500. Upon such execution, delivery, and payment and upon the satisfaction of the conditions set out in such Assignment and Acceptance, then (1) Borrower shall issue new Notes to such assignor and assignee upon return of the old Notes to Borrower, and (2) as of the “Settlement Date” specified in such Assignment and Acceptance the assignee thereunder shall be a party hereto and a Lender hereunder and Agent shall thereupon deliver to Borrower and each Lender a schedule showing the revised Percentage Shares of such assignor Lender and such assignee Lender and the Percentage Shares of all other Lenders.

(iii) Each assignee Lender which is not a United States person (as such term is defined in Section 7701(a)(30) of the Internal Revenue Code) for Federal income tax purposes, shall (to the extent it has not already done so) provide Agent and Borrower with the “Prescribed Forms” referred to in Section 3.6(d).

(iv) Unless the assignee is an Affiliate of the assignor, such assignment shall not be effective unless consented to in writing by Agent and, unless an Event of Default shall have occurred and be continuing, Borrower (such consent not to be unreasonably withheld or delayed).

(d) Nothing contained in this section shall prevent or prohibit any Lender from assigning or pledging all or any portion of its Loans and Notes to any Federal Reserve Bank as collateral security pursuant to Regulation A of the Board of Governors of the Federal Reserve System and any Operating Circular issued by such Federal Reserve Bank; provided that no such assignment or pledge shall relieve such Lender from its obligations hereunder.

(e) By executing and delivering an Assignment and Acceptance, each assignee Lender thereunder will be confirming to and agreeing with Borrower, Agent and each other Lender Party that such assignee understands and agrees to the terms hereof, including Article IX hereof.

(f) Agent shall maintain a copy of each Assignment and Acceptance and a register for the recordation of the names and addresses of Lenders and the Percentage Shares of, and principal amount of the Loans owing to, each Lender from time to time (in this section called the “Register”). The entries in the Register shall be conclusive, in the absence of manifest error, and Borrower and each Lender Party may treat each Person whose name is recorded in the Register as a Lender hereunder for all purposes. The Register shall be available for inspection by Borrower or any Lender Party at any reasonable time and from time to time upon reasonable prior notice. Agent shall act as Agent of Borrower solely for purposes of maintaining the Register as set forth in this Section 10.5(f).

Section 10.6 Confidentiality. Each Lending Party agrees to keep confidential any information furnished or made available to it by any Restricted Person pursuant to this Agreement that is financial information, information in connection with a proposed transaction, or information marked confidential; provided that nothing herein shall prevent any Lending Party from disclosing such information (a) to any other Lending Party or any Affiliate of any Lending Party, or any officer, director, employee, Agent, attorney, auditor, or advisor of any Lending Party or Affiliate of any Lending Party, (b) to any other Person if reasonably incidental to the administration of the credit facility provided herein, (c) as required by any Law, (d) upon the order of any court or administrative agency, (e) upon the request or demand of any Tribunal, (f) that is or becomes available to the public or that is or becomes available to any Lending Party other than as a result of a disclosure by any Lending Party prohibited by this Agreement, (g) to the extent necessary in connection with the exercise of any right or remedy under this Agreement or any other Loan Document, (h) subject to provisions substantially similar to those contained in this section, to any actual or proposed participant or assignee or any actual or proposed contractual counterparty (or its advisors) to any securitization, hedge, or other derivative transaction relating to the parties’ obligations hereunder, and (i) if it is otherwise available in the public domain. Notwithstanding anything set forth herein to the contrary, each party to this Agreement and each of its employees, representatives, and other Agents is hereby expressly authorized to disclose the “tax treatment” and “tax structure” (as those terms are defined in Treas. Reg. §§ 1.6011-4(c)(8) and (9), respectively) of the transactions contemplated hereby and all materials of any kind, including opinions or other tax analyses, that have been provided to it by any other party relating to such tax treatment or tax structure. Any Person required to maintain the confidentiality of information described in this section shall be considered to have complied with its obligation to do so if such Person has exercised the same degree of care to maintain the confidentiality of such information as such Person would accord to its own confidential information.

Section 10.7 Governing Law; Submission to Process. Except to the extent that the Law of another jurisdiction is expressly elected in a Loan Document, the Loan Documents shall be deemed contracts and instruments made under the Laws of the State of Texas and shall be construed and enforced in accordance with and governed by the Laws of the State of Texas and the Laws of the United States of America, without regard to principles of conflicts of law. Chapter 346 of the Texas Finance Code (which regulates certain revolving credit loan accounts and revolving tri-party accounts) does not apply to this Agreement or to the Notes. Borrower hereby irrevocably submits itself and each other Restricted Person to the exclusive jurisdiction of the state and federal courts sitting in the State of Texas and agrees and consents that service of process may be made upon it or any Restricted Person in any legal proceeding relating to the Loan Documents or the Obligations by any means allowed under Texas or federal law. Any legal proceeding arising out of or in any way related to any of the Loan Documents shall be brought and litigated exclusively in the United States District Court for the Southern District of Texas, Houston Division, to the extent it has subject matter jurisdiction, and otherwise in the Texas District Courts sitting in Harris County, Texas. The parties hereto hereby waive and agree not to assert, by way of motion, as a defense or otherwise, that any such proceeding is brought in an inconvenient forum or that the venue thereof is improper, and further agree to a transfer of any such proceeding to a federal court sitting in the State of Texas to the extent that it has subject matter jurisdiction, and otherwise to a state court in Houston, Texas. In furtherance thereof, Borrower and Lender Parties each hereby acknowledge and agree that it was not inconvenient for

them to negotiate and receive funding of the transactions contemplated by this Agreement in such county and that it will be neither inconvenient nor unfair to litigate or otherwise resolve any disputes or claims in a court sitting in such county.

Section 10.8 Limitation on Interest. Lender Parties, Restricted Persons and any other parties to the Loan Documents intend to contract in strict compliance with applicable usury Law from time to time in effect. In furtherance thereof such Persons stipulate and agree that none of the terms and provisions contained in the Loan Documents shall ever be construed to create a contract to pay, for the use, forbearance or detention of money, interest in excess of the maximum amount of interest permitted to be charged by applicable Law from time to time in effect. Neither any Restricted Person nor any present or future guarantors, endorsers, or other Persons hereafter becoming liable for payment of any Obligation shall ever be liable for unearned interest thereon or shall ever be required to pay interest thereon in excess of the maximum amount that may be lawfully contracted for, charged, or received under applicable Law from time to time in effect, and the provisions of this section shall control over all other provisions of the Loan Documents which may be in conflict or apparent conflict herewith. Lender Parties expressly disavow any intention to contract for, charge, or collect excessive unearned interest or finance charges in the event the maturity of any Obligation is accelerated. If (a) the maturity of any Obligation is accelerated for any reason, (b) any Obligation is prepaid and as a result any amounts held to constitute interest are determined to be in excess of the legal maximum, or (c) any Lender or any other holder of any or all of the Obligations shall otherwise collect moneys which are determined to constitute interest which would otherwise increase the interest on any or all of the Obligations to an amount in excess of that permitted to be charged by applicable Law then in effect, then all sums determined to constitute interest in excess of such legal limit shall, without penalty, be promptly applied to reduce the then outstanding principal of the related Obligations or, at such Lender’s or holder’s option, promptly returned to Borrower or the other payor thereof upon such determination. In determining whether or not the interest paid or payable, under any specific circumstance, exceeds the maximum amount permitted under applicable Law, Lender Parties and Restricted Persons (and any other payors thereof) shall to the greatest extent permitted under applicable Law, (i) characterize any non-principal payment as an expense, fee or premium rather than as interest, (ii) exclude voluntary prepayments and the effects thereof, and (iii) amortize, prorate, allocate, and spread the total amount of interest throughout the entire contemplated term of the instruments evidencing the Obligations in accordance with the amounts outstanding from time to time thereunder and the maximum legal rate of interest from time to time in effect under applicable Law in order to lawfully contract for, charge, or receive the maximum amount of interest permitted under applicable Law. In the event applicable Law provides for an interest ceiling under Chapter 303 of the Texas Finance Code (the “Texas Finance Code”) as amended, for that day, the ceiling shall be the “weekly ceiling” as defined in the Texas Finance Code, provided that if any applicable Law permits greater interest, the Law permitting the greatest interest shall apply. As used in this section the term “applicable Law” means the Laws of the State of Texas or the Laws of the United States of America, whichever Laws allow the greater interest, as such Laws now exist or may be changed or amended or come into effect in the future.

Section 10.9 Termination; Limited Survival.

(a) In its sole and absolute discretion Borrower may at any time that no Obligations are owing (other than indemnity obligations and similar obligations that survive the termination of this Agreement for which no notice of a claim has been received by Borrower) elect in a written notice delivered to Agent to terminate this Agreement. Upon receipt by Agent of such a notice, if no Obligations are then owing, this Agreement and all other Loan Documents shall thereupon be terminated and the parties thereto released from all prospective obligations thereunder. Notwithstanding the foregoing or anything herein to the contrary, any waivers or admissions made by any Restricted Person in any Loan Document, any Obligations under Sections 3.2 through Section 3.6, and any obligations which any Person may have to indemnify or reimburse any Lender Party shall survive any termination of this Agreement or any other Loan Document. The foregoing consent shall constitute the written consent of Required Lenders required under Section 10.1(a)(iii). At the request and expense of Borrower, Agent shall prepare and execute all necessary instruments to reflect and effect such termination of the Loan Documents. Agent is hereby authorized to execute all such instruments on behalf of all Lenders, without the joinder of or further action by any Lender.

(b) The Agent and the Lenders hereby consent to (i) the automatic release of any Liens securing the Obligations in Collateral that is sold or otherwise disposed of by a Restricted Person in compliance with this Agreement and (ii) the automatic release from the relevant Guaranty of any Guarantor that ceases to be a Subsidiary pursuant to a sale or disposal of property that is permitted by this Agreement, in each case without need for further approval of the Agent or any Lender. The foregoing consent shall constitute the written consent of Required Lenders required under clause (iii) of the fourth sentence of Section 10.1(a), with respect to such releases of Liens and Guarantors. At the request and expense of Borrower, Agent shall prepare and execute all necessary or reasonably requested instruments and documents to reflect and effect such releases of Liens and Guarantors. Agent is hereby authorized to execute all such instruments and documents on behalf of all Lenders, without the joinder of or further action by any Lender.

Section 10.10 Severability. If any term or provision of any Loan Document shall be determined to be illegal or unenforceable all other terms and provisions of the Loan Documents shall nevertheless remain effective and shall be enforced to the fullest extent permitted by applicable Law.

Section 10.11 Counterparts; Fax. This Agreement may be separately executed in any number of counterparts and by different parties hereto in separate counterparts, each of which when so executed shall be deemed to constitute one and the same Agreement. This Agreement and the Loan Documents may be validly executed and delivered by facsimile or other electronic transmission.

FOR IMMEDIATE RELEASE

COMFORT SYSTEMS USA AMENDS DEBT FACILITY; DIRECTOR RESIGNS

--- Facility Increased to $100 Million; Improved Terms, Stability and Flexibility ---

--- Steven S. Harter Resigns after Ten Years of Distinguished Service ---

Houston, TX — February 26, 2007 — Comfort Systems USA, Inc. (NYSE: FIX), a leading provider of commercial, industrial and institutional heating, ventilation and air conditioning (“HVAC”) services, today announced that it has amended its existing senior debt facility to increase the amount to $100,000,000 and improve the covenants and flexibility. Wachovia Bank has joined the Company’s bank group and is leading the facility, while the largest banks in the former agreement, which are Capital One N.A. and Bank of Texas, N.A., have remained as Co-Agents. In addition to the increased commitment, the facility now has a five-year term, lower borrowing and letter of credit costs, and provides additional flexibility for the Company with regards to acquisitions, dividends and stock buybacks.

Bill Murdy, Comfort Systems USA’s Chairman and CEO, said, “We are very pleased that our lenders have graciously provided us with improved terms and additional capacity as we work to improve Comfort Systems USA. The agreement affords our board of directors the flexibility to consider ways in which the Company might return value to its shareholders. A strong and stable facility complements our strong balance sheet and continues to provide a meaningful advantage in an industry where owners and general contractors value partners with strong financial foundations.” Mr. Murdy concluded, “This long-term facility will provide us with significant support to our operations and further strengthens our foundation for long-term growth.”

Because the Company has a strong positive net cash position, initial cash borrowings under the new credit line will be zero.

Separately, the Company announced the resignation of Steven S. Harter from its board of directors effective today, February 26, 2007. Bill Murdy commented, “Comfort Systems owes a debt to Steve Harter for his service over the last ten years. Without his founding vision, valuable guidance and specifically, his crucial role in helping obtain financing for the Company, the Company would not have reached its current standing as a respected and leading provider in the HVAC industry. We wish him well in his future endeavors.”

Comfort Systems USA® is a premier provider of business solutions addressing workplace comfort, with 60 locations in 53 cities around the nation. For more information, visit the Company’s website at www.comfortsystemsusa.com.
