Notwithstanding any contrary provision hereof, if a Default has occurred and is continuing and the Lender so notifies the Borrower Representative, then, so long as a Default is continuing (i) no outstanding Borrowing may be converted to or continued as a Eurodollar Borrowing and (ii) unless repaid, each Eurodollar Borrowing shall be converted to a CBFR Borrowing at the end of the Interest Period applicable thereto.

SECTION 2.08 Termination and Reduction of Commitment; Increase in Commitment. (a) Unless previously terminated, the Commitment shall terminate on the Maturity Date.

(b) The Borrowers may at any time terminate the Commitment upon (i) the payment in full of all outstanding Loans, together with accrued and unpaid interest thereon and on any Letters of Credit, (ii) the cancellation and return of all outstanding Letters of Credit (or alternatively, with respect to each such Letter of Credit, the furnishing to the Lender of a cash deposit, or at the discretion of the Lender a back up standby letter of credit satisfactory to the Lender, equal to 105% of the LC Exposure as of such date), (iii) the payment in full of the accrued and unpaid fees and (iv) the payment in full of all reimbursable expenses and other Obligations together with accrued and unpaid interest thereon.

(c) The Borrowers may from time to time reduce the Commitment by an aggregate amount of up to $5,000,000; provided that (i) each reduction of the Commitment shall be in an amount that is an integral multiple of $2,500,000 and (ii) the Borrowers shall not reduce the Commitment if, after giving effect to any concurrent prepayment of the Loans in accordance with Section 2.10, the sum of the Exposures would exceed the sum of (A) the lesser of (1) the Commitment or (2) the Borrowing Base, minus (B) without duplication, Reserves, minus (C) the Availability Block.

(d) The Borrower Representative shall notify the Lender of any election to terminate or reduce the Commitment under paragraph (b) or (c) of this Section at least five Business Days prior to the effective date of such termination or reduction, specifying such election and the effective date thereof. Each notice delivered by the Borrower Representative pursuant to this Section shall be irrevocable; provided that a notice of termination of the Commitment delivered by the Borrower Representative may state that such notice is conditioned upon the effectiveness of other credit facilities, in which case such notice may be revoked by the Borrower Representative (by notice to the Lender on or prior to the specified effective date) if such condition is not satisfied. Any termination or reduction of the Commitment shall be permanent.

(e) The Borrowers may request that the Lender agree, in its sole and absolute discretion, to increase the Commitment by an aggregate amount of up to $20,000,000; provided that (i) any such request for an increase shall be in a minimum amount of $5,000,000, (ii) the Borrower Representative, on behalf of the Borrowers, may make a maximum of four such requests and (iii) the procedures described in Section 2.08(f) have been satisfied.

(f) Any amendment hereto for such an increase shall be in form and substance satisfactory to the Lender in its sole and absolute discretion. As a condition precedent to such an increase, the Borrowers shall deliver to the Lender a certificate of each Loan Party signed by an authorized officer of such Loan Party (i) certifying and attaching the resolutions adopted by such Loan Party approving or consenting to such increase, and (ii) in the case of the Borrowers, certifying that, before and after giving effect to such increase, (A) the representations and warranties contained in Article III and the other Loan Documents are true and correct, except to the extent that such representations and warranties specifically refer to an earlier date, in which case they are true and correct as of such earlier date, and (B) no Default exists.

SECTION 2.09 Repayment of Loans; Evidence of Debt. (a) The Borrowers hereby unconditionally promise to pay (i) to the Lender for its account the then unpaid principal amount of each Loan on the Maturity Date and (ii) to the Lender the then unpaid amount of each Protective Advance on the earlier of the Maturity Date and demand by the Lender.

(a) At all times that Cash Dominion is in effect, each Business Day, the Lender shall apply all funds credited to the Collection Account on such Business Day or the immediately preceding Business Day (at the discretion of the Lender, whether or not immediately available) first to prepay any Protective Advances that may be outstanding and second to prepay the Loans and to cash collateralize outstanding LC Exposure.

(b) The Lender shall maintain in accordance with its usual practice an account or accounts evidencing the indebtedness of the Borrowers to the Lender resulting from each Loan made by the Lender, including the amounts of principal and interest payable and paid to the Lender from time to time hereunder.

(c) The Lender shall maintain accounts in which it shall record (i) the amount of each Loan made hereunder, the Class and Type thereof and the Interest Period applicable thereto, (ii) the amount of any principal or interest due and payable or to become due and payable from the Borrowers to the Lender hereunder and (iii) the amount of any sum received by the Lender hereunder.

(d) The entries made in the accounts maintained pursuant to paragraph (b) or (c) of this Section shall be prima facie evidence of the existence and amounts of the obligations recorded therein; provided that the failure of the Lender to maintain such accounts or any error therein shall not in any manner affect the obligation of the Borrowers to repay the Loans in accordance with the terms of this Agreement.

(e) The Lender may request that Loans made by it be evidenced by a promissory note. In such event, the Borrowers shall prepare, execute and deliver to the Lender a promissory note payable to the order of the Lender (or, if requested by the Lender, to the Lender and its registered assigns) and in a form approved by the Lender. Thereafter, the Loans evidenced by such promissory note and interest thereon shall at all times (including after assignment pursuant to Section 8.04) be represented by one or more promissory notes in such form payable to the order of the payee named therein (or, if such promissory note is a registered note, to such payee and its registered assigns).

SECTION 2.10 Prepayment of Loans. (a) The Borrowers shall have the right at any time and from time to time to prepay any Borrowing in whole or in part, subject to prior notice in accordance with paragraph (e) of this Section.

(b) In the event and on such occasion that the total Exposure exceeds the sum of (i) the lesser of (A) the Commitment or (B) the Borrowing Base, minus (ii) without duplication, Reserves, minus (iii) the Availability Block, the Borrowers shall prepay the Loans and cash collateralize LC Exposure in an aggregate amount equal to such excess.

(c) In the event and on each occasion that any Net Proceeds are received by or on behalf of any Loan Party in respect of any Prepayment Event, the Borrowers shall, immediately after such Net Proceeds are received by any Loan Party, prepay the Obligations as set forth in Section 2.10(e) below in an aggregate amount equal to 100% of such Net Proceeds, provided that, in the case of any event described in clause (a) or (b) of the definition of the term “Prepayment Event”, if the Borrower Representative shall deliver to the Lender a certificate of a Financial Officer to the effect that the Loan Parties (1) have applied or (2) intend to apply the Net Proceeds from such event (or a portion thereof specified in such certificate) within 180 days after receipt of such Net Proceeds, as applicable, to acquire (or replace or rebuild) assets used or to be used in the business of the Loan Parties, and certifying that no Default has occurred and is continuing, then either (i) so long as Cash Dominion is not in effect, no prepayment shall be required pursuant to this paragraph in respect of the Net Proceeds specified in such certificate or (ii) if Cash Dominion is in effect, then, if the Net Proceeds specified in such certificate are to be applied by (A) the Borrowers, then such Net Proceeds shall be applied by the Lender to reduce the outstanding principal balance of the Loans (without a permanent reduction of the Commitment) and upon such application, the Lender shall establish a Reserve against the Borrowing Base in an amount equal to the amount of such proceeds so applied and (B) any Loan Party that is not the Borrower, such Net Proceeds shall be deposited in a cash collateral account, and in the case of either (A) or (B), thereafter, such funds shall be made available to the applicable Loan Party as follows:

(1) the Borrower Representative shall request a Borrowing (specifying that the request is to use Net Proceeds pursuant to this Section) or the applicable Loan Party shall request a release from the cash collateral account be made in the amount needed;

(2) so long as the conditions set forth in Section 4.02 have been met, the Lender shall make such Borrowing or the Lender shall release funds from the cash collateral account; and

(3) in the case of Net Proceeds applied against the Borrowing, the Reserve established with respect to such insurance proceeds shall be reduced by the amount of such Borrowing;

provided that any such Net Proceeds therefrom that have not been so applied by the end of such 180-day period shall be applied to prepay the Loans in an amount equal to such Net Proceeds that have not been so applied.

(d) All amounts prepaid pursuant to Section 2.10(c) shall be applied, first to prepay any Protective Advances that may be outstanding and second to prepay the Loans without a corresponding reduction in the Commitment and to cash collateralize outstanding LC Exposure.

(e) The Borrower Representative shall notify the Lender by telephone (confirmed by facsimile) of any prepayment hereunder (other than a prepayment pursuant to Section 2.10(b)) not later than 10:00 a.m., Dallas, Texas time, (i) in the case of prepayment of a Eurodollar Borrowing three Business Days before the date of prepayment, or (ii) in the case of prepayment of a CBFR Borrowing on the date of prepayment. Each such notice shall be irrevocable and shall specify the prepayment date and the principal amount of each Borrowing or portion thereof to be prepaid; provided that, if a notice of prepayment is given in connection with a conditional notice of termination of the Commitment as contemplated by Section 2.08, then such notice of prepayment may be revoked if such notice of termination is revoked in accordance with Section 2.08. Each partial prepayment of any Borrowing shall be in an amount that would be permitted in the case of an advance of a Borrowing (other than a prepayment pursuant to Section 2.10(b) and 2.10(c)) of the same Type as provided in Section 2.02. Prepayments shall be accompanied by accrued interest to the extent required by Section 2.12.

SECTION 2.11 Fees. (a) The Borrowers agree to pay to the Lender a commitment fee, which shall accrue at the Applicable Rate on the average daily amount of the Available Commitment of the Lender during the period from and including the Effective Date to but excluding the date on which the Lender’s Commitment terminates. Accrued commitment fees shall be payable in arrears on the first day of each calendar quarter and on the date on which the Commitment terminates, commencing on the first such date to occur after the date hereof. All commitment fees shall be computed on the basis of a year of 360 days and shall be payable for the actual number of days elapsed.

(b) The Borrowers agree to pay (i) to the Lender a letter of credit fee with respect to Letters of Credit, which shall accrue at the same Applicable Rate used to determine the interest rate applicable to Eurodollar Loans on the average daily amount of the Lender’s LC Exposure (excluding any portion thereof attributable to unreimbursed LC Disbursements) during the period from and including the Effective Date to but excluding the later of the date on which the Lender’s Commitment terminates and the date on which the Lender ceases to have any LC Exposure, and (ii) the Lender’s standard fees with respect to the issuance, amendment, renewal or extension of any Letter of Credit or processing of drawings thereunder. Letter of credit fees accrued through and including the last day of each calendar quarter shall be payable on the first day of each calendar quarter following such last day, commencing on the first such date to occur after the Effective Date; provided that all such fees shall be payable on the date on which the Commitment terminates and any such fees accruing after the date on which the Commitment terminates shall be payable on demand. Any other fees payable to the Lender pursuant to this paragraph shall be payable within 10 days after demand. All letter of credit fees shall be computed on the basis of a year of 360 days and shall be payable for the actual number of days elapsed.

(c) The Borrowers agree to pay to the Lender an annual administration fee in the amount of $20,000, which administration fee shall be payable annually in advance beginning on the Effective Date and on each anniversary thereof during the term of the Commitment. The administration fee shall be deemed fully earned by the Lender on the first day of the year and shall be due and payable in full on that date.

(d) The Borrowers agree to pay to the Lender a closing fee in an amount equal to $100,000. The entire closing fee shall be deemed fully earned by the Lender and shall be due and payable in full on the Effective Date.

(e) The Borrowers agree to pay to the Lender at all times that Cash Dominion is in effect a fee equal to the additional interest that the Borrowers would have paid in respect of the Loans, at the CB Floating Rate plus the Applicable Margin for CBFR Loans, as if each check was received one Business Day after application to the Loans. Such fee will be payable monthly in arrears.

(f) All fees payable hereunder shall be paid on the dates due, in immediately available funds, to the Lender. Fees paid shall not be refundable under any circumstances.

SECTION 2.12 Interest. (a) The Loans comprising each CBFR Borrowing shall bear interest at the CB Floating Rate plus the Applicable Rate.

(b) The Loans comprising each Eurodollar Borrowing shall bear interest at the Adjusted LIBO Rate for the Interest Period in effect for such Borrowing plus the Applicable Rate.

(d) Notwithstanding the foregoing, during the occurrence and continuance of an Event of Default, the Lender may, at its option, by notice to the Borrower Representative, declare that (i) all Loans shall bear interest at 2% plus the rate otherwise applicable to such Loans as provided in the preceding paragraphs of this Section or (ii) in the case of any other amount outstanding hereunder, such amount shall accrue at 2% plus the rate applicable to such fee or other obligation as provided hereunder.

(e) Accrued interest on each Loan (for CBFR Loans, accrued through the last day of the prior calendar month) shall be payable in arrears on each Interest Payment Date for such Loan and upon termination of the Commitment; provided that (i) interest accrued pursuant to paragraph (d) of this Section shall be payable on demand, (ii) in the event of any repayment or prepayment of any Loan (other than a prepayment of a CBFR Loan prior to the end of the Availability Period), accrued interest on the principal amount repaid or prepaid shall be payable on the date of such repayment or prepayment and (iii) in the event of any conversion of any Eurodollar Loan prior to the end of the current Interest Period therefor, accrued interest on such Loan shall be payable on the effective date of such conversion.

(f) All interest hereunder shall be computed on the basis of a year of 360 days, except that interest computed by reference to the CB Floating Rate shall be computed on the basis of a year of 365 days (or 366 days in a leap year), and in each case shall be payable for the actual number of days elapsed. The applicable CB Floating Rate, Adjusted LIBO Rate or LIBO Rate shall be determined by the Lender, and such determination shall be conclusive absent manifest error.

SECTION 2.13 Alternate Rate of Interest. If prior to the commencement of any Interest Period for a Eurodollar Borrowing:

(a) the Lender reasonably determines (which determination shall be conclusive absent manifest error) that adequate and reasonable means do not exist for ascertaining the Adjusted LIBO Rate or the LIBO Rate, as applicable, for such Interest Period; or

(b) the Lender reasonably determines the Adjusted LIBO Rate or the LIBO Rate, as applicable, for such Interest Period will not adequately and fairly reflect the cost to the Lender of making or maintaining their Loans (or its Loan) included in such Borrowing for such Interest Period;

then the Lender shall give notice thereof to the Borrower Representative by telephone or facsimile as promptly as practicable thereafter and, until the Lender notifies the Borrower Representative that the circumstances giving rise to such notice no longer exist, (i) any Interest Election Request that requests the conversion of any Borrowing to, or continuation of any Borrowing as, a Eurodollar Borrowing shall be ineffective, and (ii) if any Borrowing Request requests a Eurodollar Borrowing, such Borrowing shall be made as a CBFR Borrowing.

SECTION 2.14 Increased Costs. (a) If any Change in Law shall:

(i)

impose, modify or deem applicable any reserve, special deposit or similar requirement against assets of, deposits with or for the account of, or credit extended by, the Lender (except any such reserve requirement reflected in the Adjusted LIBO Rate);

	(ii)		impose on the Lender or the London interbank market any other condition affecting this Agreement or Eurodollar Loans made by such Lender or any Letter of Credit or participation therein; or

	(iii)		subject the Lender to any Taxes on its loans, loan principal, letters of credit, commitments, or other obligations, or its deposits, reserves, other liabilities or capital attributable thereto (other than (A) Indemnified Taxes and (B) Other Connection Taxes on gross or net income, profits or receipts (including value-added or similar Taxes));

and the result of any of the foregoing shall be to increase the cost to the Lender of making or maintaining any Eurodollar Loan (or of maintaining its obligation to make any such Eurodollar Loan) or to increase the cost to the Lender of participating in, issuing or maintaining any Letter of Credit or to reduce the amount of any sum received or receivable by the Lender hereunder (whether of principal, interest or otherwise), then the Borrowers will pay to the Lender such additional amount or amounts as will compensate the Lender for such additional costs incurred or reduction suffered.

(b) If the Lender determines that any Change in Law regarding capital requirements has or would have the effect of reducing the rate of return on the Lender’s capital or on the capital of the Lender’s holding company, as a consequence of this Agreement or the Loans made by, Letters of Credit issued by the Lender to a level below that which the Lender or the Lender’s holding company could have achieved but for such Change in Law (taking into consideration the Lender’s policies and the policies of the Lender’s holding company with respect to capital adequacy), then from time to time the Borrowers will pay to the Lender such additional amount or amounts as will compensate the Lender or the Lender’s holding company for any such reduction suffered.

(c) A certificate of the Lender setting forth the amount or amounts necessary to compensate the Lender or its holding company, as the case may be, as specified in paragraph (a) or (b) of this Section shall be delivered to the Borrower Representative and shall be conclusive absent manifest error. The Borrowers shall pay the Lender the amount shown as due on any such certificate within 10 days after receipt thereof.

(d) Failure or delay on the part of the Lender to demand compensation pursuant to this Section shall not constitute a waiver of the Lender’s right to demand such compensation; provided that the Borrowers shall not be required to compensate a Lender pursuant to this Section for any increased costs or reductions incurred more than 270 days prior to the date that the Lender notifies the Borrower Representative of the Change in Law giving rise to such increased costs or reductions and of the Lender’s intention to claim compensation therefor; provided further that, if the Change in Law giving rise to such increased costs or reductions is retroactive, then the 270-day period referred to above shall be extended to include the period of retroactive effect thereof.

SECTION 2.15 Break Funding Payments. In the event of (a) the payment of any principal of any Eurodollar Loan other than on the last day of an Interest Period applicable thereto (including as a result of an Event of Default), (b) the conversion of any Eurodollar Loan other than on the last day of the Interest Period applicable thereto or (c) the failure to borrow, convert, continue or prepay any Eurodollar Loan on the date specified in any notice delivered pursuant hereto (regardless of whether such notice may be revoked under Section 2.08(d) and is revoked in accordance therewith), then, in any such event, the Borrowers shall compensate the Lender for the loss, cost and expense attributable to such event. In the case of a Eurodollar Loan, such loss, cost or expense to the Lender shall be deemed to include an amount determined by the Lender to be the excess, if any, of (i) the amount of interest which would have accrued on the principal amount of such Eurodollar Loan had such event not occurred, at the Adjusted LIBO Rate that would have been applicable to such Eurodollar Loan, for the period from the date of such event to the last day of the then current Interest Period therefor (or, in the case of a failure to borrow, convert or continue, for the period that would have been the Interest Period for such Eurodollar Loan), over (ii) the amount of interest which would accrue on such principal amount for such period at the interest rate which the Lender would bid were it to bid, at the commencement of such period, for dollar deposits of a comparable amount and period from other banks in the eurodollar market. A certificate of the Lender setting forth any amount or amounts that the Lender is entitled to receive pursuant to this Section shall be delivered to the Borrower Representative and shall be conclusive absent manifest error. The Borrowers shall pay the Lender the amount shown as due on any such certificate within 10 days after receipt thereof.

SECTION 2.16 Taxes. (a) Withholding of Taxes; Gross-Up. Each payment by any Loan Party under any Loan Document shall be made without withholding for any Taxes, unless such withholding is required by any law. If any Withholding Agent determines, in its sole discretion exercised in good faith, that it is so required to withhold Taxes, then such Withholding Agent may so withhold and shall timely pay the full amount of withheld Taxes to the relevant Governmental Authority in accordance with applicable law. If such Taxes are Indemnified Taxes, then the amount payable by such Loan Party shall be increased as necessary so that, net of such withholding (including such withholding applicable to additional amounts payable under this Section), the Lender receives the amount it would have received had no such withholding been made.

(b) Payment of Other Taxes by the Borrowers. The Borrowers shall timely pay any Other Taxes to the relevant Governmental Authority in accordance with applicable law.

(c) Evidence of Payments. As soon as practicable after any payment of Indemnified Taxes by any Loan Party to a Governmental Authority, such Loan Party shall deliver to the Lender the original or a certified copy of a receipt issued by such Governmental Authority evidencing such payment, a copy of the return reporting such payment or other evidence of such payment reasonably satisfactory to the Lender.

(d) Indemnification by the Loan Parties. The Loan Parties shall jointly and severally indemnify the Lender for any Indemnified Taxes that are paid or payable by the Lender in connection with any Loan Document (including amounts paid or payable under this Section 2.16(d)) and any reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. The indemnity under this Section 2.16(d) shall be paid within 10 days after the Lender delivers to any Loan Party a certificate stating the amount of any Indemnified Taxes so paid or payable by the Lender and describing the basis for the indemnification claim. Such certificate shall be conclusive of the amount so paid or payable absent manifest error.

(e) Treatment of Certain Refunds. If the Lender determines, in its sole discretion, exercised in good faith, that it has received a refund of any Taxes as to which it has been indemnified pursuant to this Section 2.16 (including additional amounts paid pursuant to this Section 2.16), it shall pay to the indemnifying party an amount equal to such refund (but only to the extent of indemnity payments made under this Section with respect to the Taxes giving rise to such refund), net of all out-of-pocket expenses (including any Taxes) of the Lender and without interest (other than any interest paid by the relevant Governmental Authority with respect to such refund). Such indemnifying party, upon the request of the Lender, shall repay to the Lender the amount paid to the Lender (plus any penalties, interest or other charges imposed by the relevant Governmental Authority) in the event the Lender is required to repay such refund to such Governmental Authority. This Section shall not be construed to require the Lender to make available its tax returns (or any other information relating to its taxes which it deems confidential) to the Borrower or any other Person. Notwithstanding anything to the contrary in this Section 2.16(e), in no event will the Lender be required to pay any amount to any indemnifying party pursuant to this Section 2.16 if such payment would place the Lender in a less favorable position (on a net after-Tax basis) than the Lender would have been in if the indemnification payments or additional amounts giving rise to such refund had never been paid. This Section 2.16(e) shall not be construed to require the Lender to make available its Tax returns (or any other information relating to its Taxes which it deems confidential) to the indemnifying party or any other Person.

SECTION 2.17 Payments Generally; Allocation of Proceeds. (a) The Borrowers shall make each payment required to be made by them hereunder (whether of principal, interest, fees or reimbursement of LC Disbursements, or of amounts payable under Section 2.14, 2.15 or 2.16, or otherwise) prior to 2:00 p.m., Dallas, Texas time, on the date when due, in immediately available funds, without set-off or counterclaim. Any amounts received after such time on any date may, in the discretion of the Lender, be deemed to have been received on the next succeeding Business Day for purposes of calculating interest thereon. All such payments shall be made to the Lender at its offices at 00 Xxxxx Xxxxxxxx Xxxxxx, 00xx Xxxxx, Xxxxxxx, Xxxxxxxx. If any payment hereunder shall be due on a day that is not a Business Day, the date for payment shall be extended to the next succeeding Business Day, and, in the case of any payment accruing interest, interest thereon shall be payable for the period of such extension. All payments hereunder shall be made in dollars.

(b) Any proceeds of Collateral received by the Lender (i) not constituting either (A) a specific payment of principal, interest, fees or other sum payable under the Loan Documents (which shall be applied as specified by the Borrowers), (B) a mandatory prepayment (which shall be applied in accordance with Section 2.10) or (C) amounts to be applied from the Collection Account when Cash Dominion is in effect (which shall be applied in accordance with Section 2.09(a)) or (ii) after an Event of Default has occurred and is continuing and the Lender so elects such funds shall be applied ratably first, to pay any fees, indemnities, or expense reimbursements including amounts then due to the Lender from the Borrowers, second, to pay interest due in respect of the Protective Advances, third, to pay the principal of the Protective Advances, fourth, to pay interest then due and payable on the Loans (other than the Protective Advances), fifth, to prepay principal on the Loans (other than the Protective Advances) and unreimbursed LC Disbursements, sixth, to pay an amount to the Lender equal to one hundred five percent (105%) of the aggregate undrawn face amount of all outstanding Letters of Credit and the aggregate amount of any unpaid LC Disbursements, to be held as cash collateral for such Obligations, seventh, to payment of any amounts owing with respect to Banking Services and Swap Obligations, and eighth, to the payment of any other Secured Obligation due to the Lender by the Borrowers. Notwithstanding anything to the contrary contained in this Agreement, unless so directed by the Borrower Representative, or unless a Default is in existence, the Lender shall not apply any payment which it receives to any Eurodollar Loan, except (a) on the expiration date of the Interest Period applicable thereto or (b) in the event, and only to the extent, that there are no outstanding CBFR Loans and, in any such event, the Borrowers shall pay the break funding payment required in accordance with Section 2.15. The Lender shall have the continuing and exclusive right to apply and reverse and reapply any and all such proceeds and payments to any portion of the Secured Obligations.

(c) At the election of the Lender, all payments of principal, interest, LC Disbursements, fees, premiums, reimbursable expenses (including, without limitation, all reimbursement for fees and expenses pursuant to Section 8.03), and other sums payable under the Loan Documents, may be paid from the proceeds of Borrowings made hereunder whether made following a request by the Borrower Representative pursuant to Section 2.03 or a deemed request as provided in this Section or may be deducted from any deposit account of any Borrower maintained with the Lender. Each Borrower hereby irrevocably authorizes (i) the Lender to make a Borrowing for the purpose of paying each payment of principal, interest and fees as it becomes due hereunder or any other amount due under the Loan Documents and agrees that all such amounts charged shall constitute Loans (but such a Borrowing may only constitute a Protective Advance if it is to reimburse costs, fees and expenses as described in Section 8.03) and that all such Borrowings shall be deemed to have been requested pursuant to Sections 2.03 or 2.04, as applicable and (ii) the Lender to charge any deposit account of any Borrower maintained with the Lender for each payment of principal, interest and fees as it becomes due hereunder or any other amount due under the Loan Documents.

SECTION 2.18 Indemnity for Returned Payments. If after receipt of any payment which is applied to the payment of all or any part of the Obligations, the Lender is for any reason compelled to surrender such payment or proceeds to any Person because such payment or application of proceeds is invalidated, declared fraudulent, set aside, determined to be void or voidable as a preference, impermissible setoff, or a diversion of trust funds, or for any other reason, then the Obligations or part thereof intended to be satisfied shall be revived and continued and this Agreement shall continue in full force as if such payment or proceeds had not been received by the Lender. The provisions of this Section 2.18 shall be and remain effective notwithstanding any contrary action which may have been taken by the Lender in reliance upon such payment or application of proceeds. The provisions of this Section 2.18 shall survive the termination of this Agreement.

SECTION 2.19 Mitigation. If the Lender requests compensation under Section 2.14, or if the Borrower is required to pay any additional amount to the Lender or any Governmental Authority for the account of the Lender pursuant to Section 2.16, then the Lender shall use reasonable efforts to designate a different lending office for funding or booking its Loans hereunder or to assign its rights and obligations hereunder to another of its offices, branches or affiliates, if, in the judgment of the Lender, such designation or assignment (i) would eliminate or reduce amounts payable pursuant to Section 2.14 or Section 2.16, as the case may be, in the future and (ii) would not subject the Lender to any unreimbursed cost or expense and would not otherwise be disadvantageous to the Lender. The Borrower hereby agrees to pay all reasonable costs and expenses incurred by the Lender in connection with any such designation or assignment.

ARTICLE III

Representations and Warranties

Each Borrower, jointly and severally, represents and warrants to the Lender that:

SECTION 3.01 Organization; Powers. Each Loan Party and its Subsidiaries is duly organized, validly existing and in good standing under the laws of the jurisdiction of its organization, has all requisite power and authority to carry on its business as now conducted and, except as could not reasonably be expected, individually or in the aggregate, to have Material Adverse Effect, is qualified to do business in, and is in good standing in, every jurisdiction where such qualification is required.

SECTION 3.03 Governmental Approvals; No Conflicts. The Transactions (a) do not require any consent or approval of, registration or filing with, or any other action by, any Governmental Authority, except such as have been obtained or made and are in full force and effect and except for filings necessary to perfect Liens created pursuant to the Loan Documents, (b) will not violate any Requirement of Law applicable to any Loan Party or any of its Subsidiaries, (c) will not violate or result in a default under any indenture, agreement or other instrument binding upon any Loan Party or any of its Subsidiaries or the assets of any Loan Party or any of its Subsidiaries, or give rise to a right thereunder to require any payment to be made by any Loan Party or any of its Subsidiaries, and (d) will not result in the creation or imposition of any Lien on any asset of any Loan Party or any of its Subsidiaries, except Liens created pursuant to the Loan Documents.

SECTION 3.04 Financial Condition; No Material Adverse Change. (a) The Borrowers have heretofore furnished to the Lender (i) Compressco Partners’ unaudited pro forma consolidated balance sheet as of March 31, 2011, and unaudited statements of income, partners equity and cash flows as of and for the portion of the fiscal year ended March 31, 2011 (the “Pro Forma Financials”), in each case reflecting on a pro-forma basis the transactions described therein, and (ii) audited combined consolidated balance sheet and statements of income, shareholders equity and cash flows of Compressco, Inc., and its subsidiaries, together with certain subsidiaries of TETRA, conducting business in Mexico (collectively, the “Predecessor”) as of and for the fiscal years 2009 and 2010, and (iii) unaudited combined consolidated balance sheet and statements of income, shareholders equity and cash flows of the Predecessor as of and for fiscal quarter and the portion of the fiscal year ended March 31, 2011 (collectively with the financial statements described in clause (ii), the “Predecessor Financials”).

(b) The Borrowers shall, jointly and severally, indemnify the Lender, and each Related Party of the Lender (each such Person being called an “Indemnitee”) against, and hold each Indemnitee harmless from, any and all losses, claims, damages, penalties, incremental taxes, liabilities and related expenses, including the fees, charges and disbursements of any counsel for any Indemnitee, incurred by or asserted against any Indemnitee arising out of, in connection with, or as a result of (i) the execution or delivery of the Loan Documents or any agreement or instrument contemplated thereby, the performance by the parties hereto of their respective obligations thereunder or the consummation of the Transactions or any other transactions contemplated hereby, (ii) any Loan or Letter of Credit or the use of the proceeds therefrom (including any refusal by the Lender to honor a demand for payment under a Letter of Credit if the documents presented in connection with such demand do not strictly comply with the terms of such Letter of Credit), (iii) any actual or alleged presence or release of Hazardous Materials on or from any property owned or operated by any Borrower or any of their Subsidiaries, or any Environmental Liability related in any way to any Borrower or any of their Subsidiaries, (iv) the failure of the Borrowers to deliver to the Lender the required receipts or other required documentary evidence with respect to a payment made by the Borrowers for Taxes pursuant to Section 2.16, or (v) any actual or prospective claim, litigation, investigation or proceeding relating to any of the foregoing, whether based on contract, tort or any other theory and regardless of whether any Indemnitee is a party thereto; provided that such indemnity shall not, as to any Indemnitee, be

available to the extent that such losses, claims, damages, penalties, liabilities or related expenses are determined by a court of competent jurisdiction by final and nonappealable judgment to have resulted from the gross negligence or wilful misconduct of such Indemnitee.WITHOUT LIMITATION OF THE FOREGOING, IT IS THE INTENTION OF THE BORROWERS AND THE BORROWERS AGREE THAT THE FOREGOING INDEMNITIES SHALL APPLY TO EACH INDEMNITEE WITH RESPECT TO LOSSES, CLAIMS, DAMAGES, PENALTIES, LIABILITIES AND RELATED EXPENSES (INCLUDING, WITHOUT LIMITATION, ALL EXPENSES OF LITIGATION OR PREPARATION THEREFOR), WHICH IN WHOLE OR IN PART ARE CAUSED BY OR ARISE OUT OF THE NEGLIGENCE OF SUCH (AND/OR ANY OTHER) INDEMNITEE.This Section 8.03(b) shall not apply with respect to Taxes other than any Taxes that represent losses or damages arising from any non-Tax claim.

(c) The relationship between any Loan Party on the one hand and the Lender on the other hand shall be solely that of debtor and creditor. The Lender (i) shall not have any fiduciary responsibilities to any Loan Party or (ii) does not undertake any responsibility to any Loan Party to review or inform such Loan Party of any matter in connection with any phase of any Loan Party’s business or operations. To the extent permitted by applicable law, no Loan Party shall assert, and each hereby waives, any claim against any Indemnitee, on any theory of liability, for special, indirect, consequential or punitive damages (as opposed to direct or actual damages) arising out of, in connection with, or as a result of, this Agreement or any agreement or instrument contemplated hereby, the Transactions, any Loan or Letter of Credit or the use of the proceeds thereof.

(d) All amounts due under this Section shall be payable upon written demand therefor.

SECTION 8.04 Successors and Assigns. (a) The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns permitted hereby, except that the Borrowers may not assign or otherwise transfer any of its rights or obligations hereunder without the prior written consent of the Lender (and any attempted assignment or transfer by the Borrowers without such consent shall be null and void). Nothing in this Agreement, expressed or implied, shall be construed to confer upon any Person (other than the parties hereto, their respective successors and assigns permitted hereby and, to the extent expressly contemplated hereby, the Related Parties of each of the Lender) any legal or equitable right, remedy or claim under or by reason of this Agreement.

(b) The Lender may assign to one or more assignees all or a portion of its rights and obligations under this Agreement (including all or a portion of its Commitment and the Loans at the time owing to it); provided that, except in the case of an assignment to an Affiliate of the Lender or an Approved Fund that in each case is organized under the laws of the United States or a state thereof or the District of Columbia, the Borrowers must give their prior written consent to such assignment (which consent shall not be unreasonably withheld but which may be conditioned on (i) in the case of an assignment that would result in there being more than one Lender, amendments to the Loan Documents reasonably satisfactory to the Borrower Representative to conform to customary agented syndicated transactions, including providing for an administrative agent reasonably satisfactory to the Borrower Representative to represent the Lenders, and (ii) in the case of an assignment to a Person not organized under the laws of the United State thereof or the District of Columbia, amendments to this Agreement reasonably satisfactory to the Borrower Representative to incorporate customary provisions relating to foreign lender, including provisions relating to withholding tax payments and maintaining and evidencing exemptions therefrom); and provided further that any consent of the Borrowers otherwise required under this paragraph shall not be required if an Event of Default has occurred and is continuing. Subject to notification of an assignment, the assignee shall be a party hereto and, to the extent of the interest assigned, have the rights and obligations of the Lender under this Agreement, and the Lender shall, to the extent of the interest assigned, be released from its obligations under this Agreement (and, in the case of an assignment covering all of the Lender’s rights and obligations under this Agreement, the Lender shall cease to be a party hereto but shall continue to be entitled to the benefits of Sections 2.14, 2.15, 2.16 and 8.03). The Borrowers hereby agree to execute any amendment and/or any other document that may be necessary to effectuate such an assignment, including an amendment to this Agreement to provide for multiple lenders and an administrative agent to act on behalf of such lenders. Any assignment or transfer by the Lender of rights or obligations under this Agreement that does not comply with this paragraph shall be treated for purposes of this Agreement as a sale by the Lender of a participation in such rights and obligations in accordance with paragraph (c) of this Section.

For the purposes of this Section 8.04(b), the term “Approved Fund” has the following meaning:

“Approved Fund” means any Person (other than a natural person) that is engaged in making, purchasing, holding or investing in bank loans and similar extensions of credit in the ordinary course of its business and that is administered or managed by (a) the Lender, (b) an Affiliate of the Lender or (c) an entity or an Affiliate of an entity that administers or manages the Lender.

(c) The Lender may, without the consent of the Borrowers, sell participations to one or more banks or other entities (a “Participant”) in all or a portion of the Lender’s rights and obligations under this Agreement (including all or a portion of its Commitment and the Loans owing to it); provided that (i) the Lender’s obligations under this Agreement shall remain unchanged, (ii) the Lender shall remain solely responsible to the other parties hereto for the performance of such obligations and (iii) the Borrowers shall continue to deal solely and directly with the Lender in connection with the Lender’s rights and obligations under this Agreement. Subject to paragraph (d) of this Section, the Borrowers agree that each Participant shall be entitled to the benefits of Sections 2.14, 2.15 and 2.16 to the same extent as if it were the Lender and had acquired its interest by assignment pursuant to paragraph (b) of this Section; provided that such Participant (A) agrees to be subject to the provisions of Sections 2.17 and 2.18 as if it were an assignee under paragraph (b) of this Section; and (B) shall not be entitled to receive any greater payment under Section 2.14 or 2.16, with respect to any participation, than its participating Lender would have been entitled to receive, except to the extent such entitlement to receive a greater payment results from a Change in Law that occurs after the Participant acquired the applicable participation.

To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 8.08 as though it were a Lender, provided such Participant agrees to be subject to Section 2.17(c) as though it were a Lender.

(d) The Lender may at any time pledge or assign a security interest in all or any portion of its rights under this Agreement to secure obligations of the Lender, including any pledge or assignment to secure obligations to a Federal Reserve Lender, and this Section shall not apply to any such pledge or assignment of a security interest; provided that no such pledge or assignment of a security interest shall release the Lender from any of its obligations hereunder or substitute any such pledgee or assignee for the Lender as a party hereto.

SECTION 8.05 Survival. All covenants, agreements, representations and warranties made by the Loan Parties in the Loan Documents and in the certificates or other instruments delivered in connection with or pursuant to this Agreement or any other Loan Document shall be considered to have been relied upon by the other parties hereto and shall survive the execution and delivery of the Loan Documents and the making of any Loans and issuance of any Letters of Credit, regardless of any investigation made by any such other party or on its behalf and notwithstanding that the Lender, the Lender or any Lender may have had notice or knowledge of any Event of Default or incorrect representation or warranty at the time any credit is extended hereunder, and shall continue in full force and effect as long as the principal of or any accrued interest on any Loan or any fee or any other amount payable under this Agreement is outstanding and unpaid or any Letter of Credit is outstanding and so long as the Commitment has not expired or terminated. The provisions of Sections 2.14, 2.15, 2.16 and Article VIII shall survive and remain in full force and effect regardless of the consummation of the transactions contemplated hereby, the repayment of the Loans, the expiration or termination of the Letters of Credit and the Commitment or the termination of this Agreement or any provision hereof.

SECTION 8.06 Counterparts; Integration; Effectiveness. This Agreement may be executed in counterparts (and by different parties hereto on different counterparts), each of which shall constitute an original, but all of which when taken together shall constitute a single contract. This Agreement, the other Loan Documents and any separate letter agreements with respect to fees payable to the Lender constitute the entire contract among the parties relating to the subject matter hereof and supersede any and all previous agreements and understandings, oral or written, relating to the subject matter hereof. Except as provided in Section 4.01, this Agreement shall become effective when it shall have been executed by the Lender and when the Lender shall have received counterparts hereof which, when taken together, bear the signatures of each of the other parties hereto, and thereafter shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns. Delivery of an executed counterpart of a signature page of this Agreement by facsimile or other electronic

transmission shall be effective as delivery of a manually executed counterpart of this Agreement. THIS WRITTEN AGREEMENT REPRESENTS 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 8.07 Severability. Any provision of any Loan Document held to be invalid, illegal or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such invalidity, illegality or unenforceability without affecting the validity, legality and enforceability of the remaining provisions thereof; and the invalidity of a particular provision in a particular jurisdiction shall not invalidate such provision in any other jurisdiction.

SECTION 8.08 Right of Setoff. If an Event of Default shall have occurred and be continuing, the Lender and each of its Affiliates is hereby authorized at any time and from time to time, to the fullest extent permitted by law, to set off and apply any and all deposits (general or special, time or demand, provisional or final) at any time held and other obligations at any time owing by the Lender or such Affiliate to or for the credit or the account of the Borrowers or any Loan Guarantor against any of and all the Secured Obligations held by the Lender, irrespective of whether or not the Lender shall have made any demand under the Loan Documents and although such obligations may be unmatured. The rights of the Lender under this Section are in addition to other rights and remedies (including other rights of setoff) which the Lender may have.

SECTION 8.09 Governing Law; Jurisdiction; Consent to Service of Process. (a) The Loan Documents (other than those containing a contrary express choice of law provision) shall be governed by and construed in accordance with the internal laws (and not the law of conflicts) of the State of Texas, but giving effect to federal laws applicable to national banks.

(a) Each Loan Party hereby irrevocably and unconditionally submits, for itself and its property, to the nonexclusive jurisdiction of any U.S. Federal or Texas State court sitting in Dallas, Texas in any action or proceeding arising out of or relating to any Loan Documents, or for recognition or enforcement of any judgment, and each of the parties hereto hereby irrevocably and unconditionally agrees that all claims in respect of any such action or proceeding may be heard and determined in such Texas State or, to the extent permitted by law, in such Federal court. Each of the parties hereto agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law. Nothing in this Agreement or any other Loan Document shall affect any right that the Lender may otherwise have to bring any action or proceeding relating to this Agreement or any other Loan Document against any Loan Party or its properties in the courts of any jurisdiction.

(b) Each Loan Party hereby irrevocably and unconditionally waives, to the fullest extent it may legally and effectively do so, any objection which it may now or hereafter have to the laying of venue of any suit, action or proceeding arising out of or relating to this Agreement or any other Loan Document in any court referred to in paragraph (a) of this Section. Each of the parties hereto hereby irrevocably waives, to the fullest extent permitted by law, the defense of an inconvenient forum to the maintenance of such action or proceeding in any such court.

(c) Each party to this Agreement irrevocably consents to service of process in the manner provided for notices in Section 8.01. Nothing in this Agreement or any other Loan Document will affect the right of any party to this Agreement to serve process in any other manner permitted by law.

SECTION 8.10 WAIVER OF JURY TRIAL. EACH PARTY HERETO HEREBY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT, ANY OTHER LOAN DOCUMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY (WHETHER BASED ON CONTRACT, TORT OR ANY OTHER THEORY). EACH PARTY HERETO (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT,

IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION.

SECTION 8.11 Headings. Article and Section headings and the Table of Contents used herein are for convenience of reference only, are not part of this Agreement and shall not affect the construction of, or be taken into consideration in interpreting, this Agreement.

SECTION 8.12 Confidentiality. The Lender agrees to maintain the confidentiality of the Information (as defined below), except that Information may be disclosed (a) to its and its Affiliates’ directors, officers, employees and agents, including accountants, legal counsel and other advisors (it being understood that the Persons to whom such disclosure is made will be informed of the confidential nature of such Information and instructed to keep such Information confidential), (b) to the extent requested by any regulatory authority, (c) to the extent required by Requirement of Law or by any subpoena or similar legal process, (d) to any other party to this Agreement, (e) in connection with the exercise of any remedies hereunder or any suit, action or proceeding relating to this Agreement or any other Loan Document or the enforcement of rights hereunder or thereunder, (f) subject to an agreement containing provisions substantially the same as those of this Section, to (i) any assignee of or Participant in, or any prospective assignee of or Participant in, any of its rights or obligations under this Agreement or (ii) any actual or prospective counterparty (or its advisors) to any swap or derivative transaction relating to the Loan Parties and their obligations, (g) with the consent of the Borrower Representative or (h) to the extent such Information (i) becomes publicly available other than as a result of a breach of this Section or (ii) becomes available to the Lender on a non-confidential basis from a source other than the Borrowers. For the purposes of this Section, “Information” means all information received from the Borrowers relating to the Borrowers or their business, other than any such information that is available to the Lender on a non-confidential basis prior to disclosure by the Borrowers; provided that, in the case of information received from the Borrowers after the date hereof, such information is clearly identified at the time of delivery as confidential. Any Person required to maintain the confidentiality of Information as provided in this Section shall be considered to have complied with its obligation to do so if such Person has exercised the same degree of care to maintain the confidentiality of such Information as such Person would accord to its own confidential information.

SECTION 8.13 Nonreliance; Violation of Law. The Lender hereby represents that it is not relying on or looking to any margin stock for the repayment of the Borrowings provided for herein. Anything contained in this Agreement to the contrary notwithstanding, the Lender shall not be obligated to extend credit to the Borrowers in violation of any Requirement of Law.

SECTION 8.14 USA PATRIOT Act. The Lender is subject to the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)) (the “Act”) and hereby notifies the Borrowers that pursuant to the requirements of the Act, it is required to obtain, verify and record information that identifies the Borrowers, which information includes the names and addresses of the Borrowers and other information that will allow such Lender to identify the Borrowers in accordance with the Act.

SECTION 8.15 Disclosure. Each Loan Party hereby acknowledges and agrees that the Lender and/or its Affiliates from time to time may hold investments in, make other loans to or have other relationships with any of the Loan Parties and their respective Affiliates.

SECTION 8.16 Interest Rate Limitation. Notwithstanding anything herein to the contrary, if at any time the interest rate applicable to any Loan, together with all fees, charges and other amounts which are treated as interest on such Loan under applicable law (collectively the “Charges”), shall exceed the maximum lawful rate (the “Maximum Rate”) which may be contracted for, charged, taken, received or reserved by the Lender holding such Loan in accordance with applicable law, the rate of interest payable in respect of such Loan hereunder, together with all Charges payable in respect thereof, shall be limited to the Maximum Rate and, to the extent lawful, the interest and Charges that would have been payable in respect of such Loan but were not payable as a result of the operation of this Section shall be cumulated and the interest and Charges payable to such Lender in respect of other Loans or periods shall be increased (but not above the Maximum Rate therefor) until such

cumulated amount, together with interest thereon at the Federal Funds Effective Rate to the date of repayment, shall have been received by such Lender.

SECTION 8.17 Releases of Guarantees and Liens.

(a) Notwithstanding anything to the contrary contained herein or in any other Loan Document, at such time as the Loans and the other obligations under the Loan Documents (other than contingent indemnification obligations and obligations under or in respect of Swap Agreements and Bank Services Obligations) shall have been irrevocably paid in full, the Commitment has been terminated and no Letters of Credit shall be outstanding (other than Letters of Credit that have been cash collateralized or otherwise backstopped in a manner satisfactory to the Lender), the Collateral shall be released from the Liens created by the Loan Documents, and the Collateral Documents and all obligations (other than those expressly stated to survive such termination) of each Loan Party under the Collateral Documents shall terminate, all without delivery of any instrument or performance of any act by any Person; and

(b) If any of the Collateral shall be sold, transferred or otherwise disposed of by any Borrower or any Subsidiary in a transaction not prohibited by this Agreement, then the Lender, at the request and sole expense of any Borrower or any Subsidiary, shall execute and deliver to such Borrower or such Subsidiary at the Borrowers’ sole expense all releases or other documents reasonably necessary or desirable for the release of the Liens created by the Collateral Documents on such Collateral. At the request and sole expense of any Borrower, a Loan Party shall be released from its obligations hereunder and under the other Loan Documents in the event that all the Equity Interests of such Loan Party shall be disposed of in a transaction not prohibited by this Agreement; provided that, unless otherwise waived by the Administrative Agent, the Borrower Representative shall have delivered to the Administrative Agent, at least five (5) Business Days prior to the date of the proposed release, a written request for release identifying the relevant Loan Party and the terms of the disposition in reasonable detail, together with a certification by the Borrower Representative stating that such transaction is in compliance with this Agreement and the other Loan Documents.

SECTION 8.18 Limitation of Liability. Compressco GP, as general partner of Compressco Partners, shall not be liable for the obligations of any Loan Party under this Agreement or any other Loan Document, including, without limitation, by reason of any payment obligation imposed by governing state partnership statutes and any provision of the applicable limited partnership agreement of Compressco Partners or any other Loan Party that requires Compressco GP to restore a capital account deficit; provided that nothing in this Section 8.18 shall be construed so as to prevent the Lender from commencing any action, suit or proceeding with respect to or causing legal papers to be served upon Compressco GP for the purpose of (a) obtaining jurisdiction over Compressco Partners or (b) obtaining any judgment, order or execution against Compressco GP arising out of any fraud or intentional misrepresentation by Compressco GP in connection with the Loan Documents or in order to recover moneys received by Compressco GP in violation of the terms of this Agreement.

ARTICLE IX

Loan Guaranty

SECTION 9.01 Guaranty. Each Loan Guarantor (other than those that have delivered a separate Guaranty) hereby agrees that it is jointly and severally liable for, and absolutely and unconditionally guarantees to the Lender the prompt payment when due, whether at stated maturity, upon acceleration or otherwise, and at all times thereafter, of the Secured Obligations and all costs and expenses including, without limitation, all court costs and attorneys’ and paralegals’ fees (including allocated costs of in-house counsel and paralegals) and expenses paid or incurred by the Lender in endeavoring to collect all or any part of the Secured Obligations from, or in prosecuting any action against, any Borrower, any Loan Guarantor or any other guarantor of all or any part of the Secured Obligations (such costs and expenses, together with the Secured Obligations, collectively the “Guaranteed Obligations”). Each Loan Guarantor further agrees that the Guaranteed Obligations may be extended or renewed in whole or in part without notice to or further assent from it, and that it remains bound upon its guarantee notwithstanding any such extension or renewal. All terms of this Loan Guaranty apply to and may be enforced by

or on behalf of any domestic or foreign branch or Affiliate of any Lender that extended any portion of the Guaranteed Obligations.

SECTION 9.02 Guaranty of Payment. This Loan Guaranty is a guaranty of payment and not of collection. Each Loan Guarantor waives any right to require the Lender to xxx any Borrower, any Loan Guarantor, any other guarantor, or any other Person obligated for all or any part of the Guaranteed Obligations (each, an “Obligated Party”), or otherwise to enforce its payment against any collateral securing all or any part of the Guaranteed Obligations.

SECTION 9.03 No Discharge or Diminishment of Loan Guaranty. (a) Except as otherwise provided for herein, the obligations of each Loan Guarantor hereunder are unconditional and absolute and not subject to any reduction, limitation, impairment or termination for any reason (other than the indefeasible payment in full in cash of the Guaranteed Obligations), including: (i) any claim of waiver, release, extension, renewal, settlement, surrender, alteration, or compromise of any of the Guaranteed Obligations, by operation of law or otherwise; (ii) any change in the corporate existence, structure or ownership of any Borrower or any other Obligated Party liable for any of the Guaranteed Obligations; (iii) any insolvency, bankruptcy, reorganization or other similar proceeding affecting any Obligated Party, or their assets or any resulting release or discharge of any obligation of any Obligated Party; or (iv) the existence of any claim, setoff or other rights which any Loan Guarantor may have at any time against any Obligated Party, Lender, or any other person, whether in connection herewith or in any unrelated transactions.

(b) The obligations of each Loan Guarantor hereunder are not subject to any defense or setoff, counterclaim, recoupment, or termination whatsoever by reason of the invalidity, illegality, or unenforceability of any of the Guaranteed Obligations or otherwise, or any provision of applicable law or regulation purporting to prohibit payment by any Obligated Party, of the Guaranteed Obligations or any part thereof.

(c) Further, the obligations of any Loan Guarantor hereunder are not discharged or impaired or otherwise affected by: (i) the failure of the Lender to assert any claim or demand or to enforce any remedy with respect to all or any part of the Guaranteed Obligations; (ii) any waiver or modification of or supplement to any provision of any agreement relating to the Guaranteed Obligations; (iii) any release, non-perfection, or invalidity of any indirect or direct security for the obligations of any Borrower for all or any part of the Guaranteed Obligations or any obligations of any other Obligated Party liable for any of the Guaranteed Obligations; (iv) any action or failure to act by the Lender with respect to any collateral securing any part of the Guaranteed Obligations; or (v) any default, failure or delay, willful or otherwise, in the payment or performance of any of the Guaranteed Obligations, or any other circumstance, act, omission or delay that might in any manner or to any extent vary the risk of such Loan Guarantor or that would otherwise operate as a discharge of any Loan Guarantor as a matter of law or equity (other than the indefeasible payment in full in cash of the Guaranteed Obligations).

SECTION 9.04 Defenses Waived. To the fullest extent permitted by applicable law, each Loan Guarantor hereby waives any defense based on or arising out of any defense of any Borrower or any Loan Guarantor or the unenforceability of all or any part of the Guaranteed Obligations from any cause, or the cessation from any cause of the liability of any Borrower or any Loan Guarantor, other than the indefeasible payment in full in cash of the Guaranteed Obligations. Without limiting the generality of the foregoing, each Loan Guarantor irrevocably waives acceptance hereof, presentment, demand, protest and, to the fullest extent permitted by law, any notice not provided for herein, as well as any requirement that at any time any action be taken by any Person against any Obligated Party, or any other Person. Each Loan Guarantor confirms that it is not a surety under any state law and shall not raise any such law as a defense to its obligations hereunder. The Lender may, at its election, foreclose on any Collateral held by it by one or more judicial or nonjudicial sales, accept an assignment of any such Collateral in lieu of foreclosure or otherwise act or fail to act with respect to any collateral securing all or a part of the Guaranteed Obligations, compromise or adjust any part of the Guaranteed Obligations, make any other accommodation with any Obligated Party or exercise any other right or remedy available to it against any Obligated Party, without affecting or impairing in any way the liability of such Loan Guarantor under this Loan Guaranty except to the extent the Guaranteed Obligations have been fully and indefeasibly paid in cash. To the fullest extent permitted by applicable law, each Loan Guarantor waives any defense arising out of any such election even though

that election may operate, pursuant to applicable law, to impair or extinguish any right of reimbursement or subrogation or other right or remedy of any Loan Guarantor against any Obligated Party or any security.

SECTION 9.05 Rights of Subrogation. No Loan Guarantor will assert any right, claim or cause of action, including, without limitation, a claim of subrogation, contribution or indemnification that it has against any Obligated Party, or any collateral, until the Loan Parties and the Loan Guarantors have fully performed all their obligations to the Lender.

SECTION 9.06 Reinstatement; Stay of Acceleration. If at any time any payment of any portion of the Guaranteed Obligations is rescinded or must otherwise be restored or returned upon the insolvency, bankruptcy, or reorganization of any Borrower or otherwise, each Loan Guarantor’s obligations under this Loan Guaranty with respect to that payment shall be reinstated at such time as though the payment had not been made and whether or not the Lender is in possession of this Loan Guaranty. If acceleration of the time for payment of any of the Guaranteed Obligations is stayed upon the insolvency, bankruptcy or reorganization of any Borrower, all such amounts otherwise subject to acceleration under the terms of any agreement relating to the Guaranteed Obligations shall nonetheless be payable by the Loan Guarantors forthwith on demand by the Lender.

SECTION 9.07 Information. Each Loan Guarantor assumes all responsibility for being and keeping itself informed of the Borrowers’ financial condition and assets, and of all other circumstances bearing upon the risk of nonpayment of the Guaranteed Obligations and the nature, scope and extent of the risks that each Loan Guarantor assumes and incurs under this Loan Guaranty, and agrees that the Lender shall not have any duty to advise any Loan Guarantor of information known to it regarding those circumstances or risks.

SECTION 9.08 Termination. The Lender may continue to make loans or extend credit to the Borrowers based on this Loan Guaranty until five days after it receives written notice of termination from any Loan Guarantor. Notwithstanding receipt of any such notice, each Loan Guarantor will continue to be liable to the Lender for any Guaranteed Obligations created, assumed or committed to prior to the fifth day after receipt of the notice, and all subsequent renewals, extensions, modifications and amendments with respect to, or substitutions for, all or any part of that Guaranteed Obligations.

SECTION 9.09 Taxes. Each payment of the Guaranteed Obligations will be made by each Loan Guarantor without withholding for any Taxes, unless such withholding is required by law. If any Loan Guarantor determines, in its sole discretion exercised in good faith, that it is so required to withhold Taxes, then such Loan Guarantor may so withhold and shall timely pay the full amount of withheld Taxes to the relevant Governmental Authority in accordance with applicable law. If such Taxes are Indemnified Taxes, then the amount payable by such Loan Guarantor shall be increased as necessary so that, net of such withholding (including such withholding applicable to additional amounts payable under this Section), the Lender receives the amount it would have received had no such withholding been made.

SECTION 9.10 Maximum Liability. The provisions of this Loan Guaranty are severable, and in any action or proceeding involving any state corporate law, or any state, federal or foreign bankruptcy, insolvency, reorganization or other law affecting the rights of creditors generally, if the obligations of any Loan Guarantor under this Loan Guaranty would otherwise be held or determined to be avoidable, invalid or unenforceable on account of the amount of such Loan Guarantor’s liability under this Loan Guaranty, then, notwithstanding any other provision of this Loan Guaranty to the contrary, the amount of such liability shall, without any further action by the Loan Guarantors or the Lender, be automatically limited and reduced to the highest amount that is valid and enforceable as determined in such action or proceeding (such highest amount determined hereunder being the relevant Loan Guarantor’s “Maximum Liability”). This Section with respect to the Maximum Liability of each Loan Guarantor is intended solely to preserve the rights of the Lender to the maximum extent not subject to avoidance under applicable law, and no Loan Guarantor nor any other Person shall have any right or claim under this Section with respect to such Maximum Liability, except to the extent necessary so that the obligations of any Loan Guarantor hereunder shall not be rendered voidable under applicable law. Each Loan Guarantor agrees that the Guaranteed Obligations may at any time and from time to time exceed the Maximum Liability of each Loan Guarantor without impairing this Loan Guaranty or affecting the rights and remedies of the Lender hereunder,

provided that, nothing in this sentence shall be construed to increase any Loan Guarantor’s obligations hereunder beyond its Maximum Liability.

SECTION 9.11 Contribution. In the event any Loan Guarantor (a “Paying Guarantor”) shall make any payment or payments under this Loan Guaranty or shall suffer any loss as a result of any realization upon any collateral granted by it to secure its obligations under this Loan Guaranty, each other Loan Guarantor (each a “Non-Paying Guarantor”) shall contribute to such Paying Guarantor an amount equal to such Non-Paying Guarantor’s “Applicable Percentage” of such payment or payments made, or losses suffered, by such Paying Guarantor. For purposes of this Article IX, each Non-Paying Guarantor’s “Applicable Percentage” with respect to any such payment or loss by a Paying Guarantor shall be determined as of the date on which such payment or loss was made by reference to the ratio of (i) such Non-Paying Guarantor’s Maximum Liability as of such date (without giving effect to any right to receive, or obligation to make, any contribution hereunder) or, if such Non-Paying Guarantor’s Maximum Liability has not been determined, the aggregate amount of all monies received by such Non-Paying Guarantor from the Borrowers after the date hereof (whether by loan, capital infusion or by other means) to (ii) the aggregate Maximum Liability of all Loan Guarantors hereunder (including such Paying Guarantor) as of such date (without giving effect to any right to receive, or obligation to make, any contribution hereunder), or to the extent that a Maximum Liability has not been determined for any Loan Guarantor, the aggregate amount of all monies received by such Loan Guarantors from the Borrowers after the date hereof (whether by loan, capital infusion or by other means). Nothing in this provision shall affect any Loan Guarantor’s several liability for the entire amount of the Guaranteed Obligations (up to such Loan Guarantor’s Maximum Liability). Each of the Loan Guarantors covenants and agrees that its right to receive any contribution under this Loan Guaranty from a Non-Paying Guarantor shall be subordinate and junior in right of payment to the payment in full in cash of the Guaranteed Obligations. This provision is for the benefit of the Lender and the Loan Guarantors and may be enforced by any one, or more, or all of them in accordance with the terms hereof.

SECTION 9.12 Liability Cumulative. The liability of each Loan Party as a Loan Guarantor under this Article IX is in addition to and shall be cumulative with all liabilities of each Loan Party to the Lender under this Agreement and the other Loan Documents to which such Loan Party is a party or in respect of any obligations or liabilities of the other Loan Parties, without any limitation as to amount, unless the instrument or agreement evidencing or creating such other liability specifically provides to the contrary.

ARTICLE X

The Borrower Representative

SECTION 10.01 Appointment; Nature of Relationship. Compressco Partners is hereby appointed by each of the Borrowers as its contractual representative (herein referred to as the “Borrower Representative”) hereunder and under each other Loan Document, and each of the Borrowers irrevocably authorizes the Borrower Representative to act as the contractual representative of such Borrower with the rights and duties expressly set forth herein and in the other Loan Documents. The Borrower Representative agrees to act as such contractual representative upon the express conditions contained in this Article X. Additionally, the Borrowers hereby appoint the Borrower Representative as their agent to receive all of the proceeds of the Loans, at which time the Borrower Representative shall promptly disburse such Loans to the appropriate Borrower, provided that, in the case of a Loan, such amount shall not exceed such Borrower’s Availability. The Lender and its respective officers, directors, agents or employees, shall not be liable to the Borrower Representative or any Borrower for any action taken or omitted to be taken by the Borrower Representative or the Borrowers pursuant to this Section 10.01.

SECTION 10.02 Powers. The Borrower Representative shall have and may exercise such powers under the Loan Documents as are specifically delegated to the Borrower Representative by the terms of each thereof, together with such powers as are reasonably incidental thereto. The Borrower Representative shall have no implied duties to the Borrowers, or any obligation to the Lender to take any action thereunder except any action specifically provided by the Loan Documents to be taken by the Borrower Representative.

SECTION 10.03 Employment of Agents. The Borrower Representative may execute any of its duties as the Borrower Representative hereunder and under any other Loan Document by or through authorized officers.

SECTION 10.04 Notices. Each Borrower shall immediately notify the Borrower Representative of the occurrence of any Default or Event of Default hereunder referring to this Agreement describing such Default or Event of Default and stating that such notice is a “notice of default.” In the event that the Borrower Representative receives such a notice, the Borrower Representative shall give prompt notice thereof to the Lender. Any notice provided to the Borrower Representative hereunder shall constitute notice to each Borrower on the date received by the Borrower Representative.

SECTION 10.05 Successor Borrower Representative. Upon the prior written consent of the Lender, the Borrower Representative may resign at any time, such resignation to be effective upon the appointment of a successor Borrower Representative.

SECTION 10.06 Execution of Loan Documents; Borrowing Base Certificate. The Borrowers hereby empower and authorize the Borrower Representative, on behalf of the Borrowers, to execute and deliver to the Lender the Loan Documents and all related agreements, certificates, documents, or instruments as shall be necessary or appropriate to effect the purposes of the Loan Documents, including without limitation, the Borrowing Base Certificates and the Compliance Certificates. Each Borrower agrees that any action taken by the Borrower Representative or the Borrowers in accordance with the terms of this Agreement or the other Loan Documents, and the exercise by the Borrower Representative of its powers set forth therein or herein, together with such other powers that are reasonably incidental thereto, shall be binding upon all of the Borrowers.

SECTION 10.07 Reporting. Each Borrower hereby agrees that such Borrower shall furnish promptly after each fiscal month to the Borrower Representative a copy of its Borrowing Base Certificate and any other certificate or report required hereunder or requested by the Borrower Representative on which the Borrower Representative shall rely to prepare the Borrowing Base Certificates and Compliance Certificates required pursuant to the provisions of this Agreement.
