REVOLVING LOANS

Section 2.1.  The Revolving Loan Commitment.  Subject to the terms and conditions of this Agreement, Bank agrees to extend credit to Borrowers during the period from the date hereof until the Termination Date by (a) making Revolving Loans to Borrowers from time to time, and (b) issuing irrevocable standby and commercial letters of credit (said irrevocable standby and commercial letters of credit being referred to herein as the "Letters of Credit") for the account of Borrowers or either one of them; provided, however, that (1) at no time shall the sum of (i) the aggregate principal amount of Revolving Loans to Borrowers at such time outstanding, plus (ii) the aggregate unfunded amount of Letters of Credit issued for the account of Borrowers at such time outstanding (said sum, at any time, being hereinafter referred to as the "Bank's Current Revolving Loan Commitment Exposure"), exceed the Borrowing Base Amount then in effect, and (2) at no time shall the aggregate unfunded amount of Letters of Credit issued for the account of Borrowers (or for the account of either of them) at such time outstanding exceed the amount of $500,000.00.  In the event, at any time, and from time to time, the Bank's Current Revolving Loan Commitment Exposure exceeds the Borrowing Base Amount then in effect, Borrowers shall immediately prepay the Revolving Loans by such an amount to cause the Bank's Current Revolving Loan Commitment Exposure to equal the Borrowing Base Amount (or, at the option of Bank, Borrowers may post cash collateral or other collateral acceptable to Bank in its sole discretion to secure such deficiency in the Borrowing Base Amount).  Within the limits set forth herein, Borrowers may borrow from Bank hereunder, repay any and all such Revolving Loans as hereinafter provided and reborrow hereunder.  Borrowers' obligation to repay the Revolving Loans made by Bank shall be evidenced by a master promissory note made by Borrowers as co-makers (the "Revolving Note") payable to the order of Bank in the principal sum of $8,883,997.00, dated the date of this Agreement, with a final maturity of December 27, 2003, and bearing interest at the Base Rate plus the Applicable Margin from time to time in effect.  The Borrowers shall be solidarily liable for all Revolving Loans, Letters of Credit (and reimbursement obligations arising thereunder) and other obligations to Bank arising pursuant to this Agreement or the Revolving Note.

Section 2.2.  Manner and Notice of Borrowing Under the Revolving Loan Commitment.  Requests for advances under the Revolving Loan Commitment, other than daily fundings under controlled disbursement, shall be made by Borrowers  in writing  to Bank and include certificates required under Section 8.1(e) of this Agreement.  Requests for advances must be received by not later than 12:00 p.m. (Central Time) on the date of the proposed advance.

Section 2.3.  Payment of the Revolving Note Under the Revolving Loan Commitment.  Interest on the unpaid principal balance of the Revolving Note shall be payable monthly in arrears on the first day of each month, commencing January 1, 2002, and on the first day of each month thereafter until the Revolving Note is paid in full.  All principal shall be payable in a single installment due on the Termination Date; subject to, however, the mandatory prepayment requirement set forth above in Section 2.1 hereof which requires Borrowers to prepay the Revolving Loans under the Revolving Note in the event, at any time and from time to time, the Bank's Current Revolving Loan Commitment Exposure exceeds the Borrowing Base Amount then in effect (or which, at the option of Bank, requires that Borrowers post cash collateral or other collateral acceptable to Bank in its sole discretion, to secure such deficiency in its Borrowing Base Amount).  Borrowers hereby authorize Bank to debit their checking accounts maintained with Bank to pay interest due on the Revolving Note on each interest payment date and to credit all proceeds of their Receivables received in the Dominion Account when collected (or earlier, if Bank in its sole discretion allows such funds to be available to Borrowers prior to the date on which any checks or other instruments given in payment of Receivables are actually collected) towards payment of the Revolving Loans outstanding under the Revolving Note.

Section 2.4.  Proceeds of Dominion Account.  Borrowers have executed an agreement with Bank, pursuant to which all checks, drafts and other instruments evidencing payment of Borrowers' Receivables shall be delivered to Bank and deposited into Borrowers' Dominion Account more fully described in Section 8.15 hereof.  Borrowers authorize Bank to apply, from time to time, at Borrower's request, the proceeds of their Receivables actually collected (or, at the sole discretion of Bank, amounts which have been received but not yet collected) by the Bank from the Dominion Account to reduce in whole or in part the outstanding principal balance of the Revolving Loans due under the Revolving Note.  Such payments will adjust for loan availability,  bookkeeping and interest purposes on the second day after deposit.

Section 2.5.  Overlines and Overadvances.  In the event the unpaid principal amount of the outstanding Revolving Loans and Letters of Credit under the Revolving Loan Commitment ever exceeds the maximum Borrowing Base Amount), Borrowers agree to pay the excess amount (an "overline") immediately upon demand by Bank.  In the event the unpaid principal amount of the outstanding Revolving Loans and Letters of Credit under the Revolving Loan Commitment ever exceeds the current Borrowing Base Amount then in effect, Borrowers agree to pay the excess amount (an "overadvance") immediately upon demand by Bank.  Overlines and overadvances shall bear interest at the rate stated in the Note.  If not sooner paid, interest on overlines and overadvances shall be paid on the first day of each month, until the Termination Date.  Upon request of Bank, Borrowers shall execute a promissory note, payable to the order of Bank, to represent the amount of any overline and any overadvance; however, Borrowers acknowledge and agree that the records of Bank and this Agreement shall constitute conclusive evidence of any overline or overadvance and the obligation of Borrowers to repay any overline or overadvance, with interest.  All overlines and overadvances for which Bank has not demanded payment earlier, and all unpaid and accrued interest on overlines and overadvances not due and payable earlier, shall be due and payable on the Termination Date.  Borrowers acknowledge and agree that Bank is not obligated to Borrowers to make any Revolving Loan or issue Letters of Credit that would create an overline or an overadvance.

Section 2.6.  Early Termination.  Bank agrees that Borrowers shall have the right to terminate this Agreement prior to the Termination Date upon Borrowers (a) giving Bank ninety (90) days' written notice of termination and designating a termination effective date, and (b) paying to Bank on the designated termination effective date, the aggregate unpaid principal amount of all Revolving Loans then outstanding and all accrued unpaid interest, together with all other applicable fees, costs and charges, if any, not yet paid.

Section 2.7.  Use of Proceeds.  Borrowers shall use the proceeds of the Revolving Loans for general corporate purposes (but not for the purchase of any producing oil and gas properties).

ARTICLE III

LETTERS OF CREDIT

Section 3.1.  The Letters of Credit.  Upon the written application of Borrowers (or any one of them), using the form or forms of letter of credit applications currently in use by Bank (the "Letter of Credit Application"), executed by Borrowers (or by any one of the persons designated by Borrowers in writing to Bank in accordance with the terms hereof), Bank agrees, upon satisfaction of the terms and conditions of this Agreement and upon approval by Bank (in its sole discretion) of the terms of the requested Letter of Credit to be issued pursuant to the Letter of Credit Application, that it will issue an irrevocable standby letter of credit or commercial letter of credit for the account of Borrowers or either one of them (a "Letter of Credit") substantially in accordance with the Letter of Credit Application.  Each Letter of Credit issued hereunder shall expire on a Business Day which is the earlier to occur of (i) twelve months from the date of issuance of such Letter of Credit, or (ii) the Termination Date.  In no event shall a Letter of Credit be issued by Bank if the sum of the face amount thereof when added to the aggregate unfunded amount of Letters of Credit then outstanding plus the aggregate principal amount of the Revolving Loans at such time outstanding would exceed Borrowing Base Amount, and in no event shall a Letter of Credit be issued if the face amount thereof when added to the aggregate unfunded amount of Letters of Credit then outstanding would exceed $500,000.00.

Section 3.2.  Issuance of Letters of Credit.  Each Letter of Credit shall be issued not later than three (3) Business Days after receipt by Bank of the Letter of Credit Application related thereto.  No later than 12:00 noon (New Orleans time) on the third Business Day following receipt of the Letter of Credit Application and upon fulfillment of the applicable conditions set forth in this Agreement, Bank shall issue its Letter of Credit.  Bank may rely fully and completely upon the authority of the signatory of the Letter of Credit Application and the contents thereof unless such authority is terminated by written notice delivered to Bank, and any such termination of authority shall be effective only prospectively.

Section 3.3.  Letter of Credit Fee.  Borrowers agree to pay to Bank a fee equal to one and a half percent (1.5%) per annum of the face amount of each Letter of Credit issued by Bank hereunder (the "Letter of Credit Commission") plus any other fees customarily charged by Bank for Letters of Credit such as issuance and courier fees.  Payment of such Letter of Credit Commission with respect to each Letter of Credit created by Bank shall be paid in advance on the date of issuance of the Letter of Credit and on each anniversary date of any such Letter of Credit.

Section 3.4.  Letter of Credit Obligations.  Borrowers agree unconditionally to pay Bank on demand in United States currency at Bank's principal office in New Orleans, Louisiana, the amount required to pay (a) any and all drafts drawn and any and all demands made or purported to be made under any Letter of Credit, (b) any and all costs, charges, fees and/or expenses incurred or paid by Bank in connection with any Letter of Credit, (c) interest on such amounts described above under (a) and (b) as hereinafter provided, and (d) a fee equal to one-eighth of one percent (0.125%) of the amount of each such draft drawn and demand made or purported to be made under any Letter of Credit (the "Letter of Credit Obligations").  In the event of any drafts drawn and any and all demands made under any Letter of Credit are payable in foreign currency, Borrowers agree to make the aforementioned payment to Bank in United States currency at Bank's selling rate for cable transfers to the place of payment of such draft on the date of such payment.  Such obligation of Borrowers shall be deemed a Letter of Credit Obligation hereunder.  Borrowers further agree to comply with any and all governmental currency exchange regulations or requirements now or hereafter applicable to such Letter of Credit or to any drafts related thereto.  Borrowers further authorize Bank, at its option, to compensate itself by applying any part or all of the balance of any deposit account or certificate of deposit which Borrowers may maintain with Bank, at any time, whether or not the deposit is mature, and/or any and all monies or property or interest of any kind now or hereafter in Bank's hands, or in transit to or from Bank, and belonging to Borrowers, to the payment, in whole or in part, of the amount of any draft and all interest, costs and reasonable attorney's fees which Borrowers may owe Bank pursuant to this Agreement.  In the event a Letter of Credit Obligation is not paid when demanded by Bank, Borrowers agree to pay to Bank on demand a sum equal to the amount of the Letter of Credit Obligation, plus interest thereon from the date the Letter of Credit Obligation is demanded by Bank until paid at the Base Rate plus 1.5%.  A payment shall not be deemed made until funds therefor have been actually collected and made available to Bank.  Upon the occurrence of an Event of Default hereunder, Borrowers agree to pay to Bank on demand a sum equal to the aggregate unfunded amounts of all Letters of Credit outstanding, together with interest thereon (such obligation of Borrower shall be deemed a Letter of Credit Obligation as such term is used herein).  Upon the occurrence of such Event of Default, Bank may exercise its right of offset and compensation set forth above in this paragraph.  Any amount which Bank offsets or which Borrowers may pay to Bank in excess of drafts actually drawn on any outstanding Letters of Credit shall be held by Bank in pledge to secure the payment of future drafts until Bank's obligation to make Revolving Loans have been terminated, all Indebtedness has been paid in full, and no further Letters of Credit are outstanding.

Section 3.5.  Revolving Loans.  In the event that Letter of Credit Obligations owed Bank are not paid when due for any reason including Letter of Credit Obligations arising upon occurrence of an Event of Default hereunder, or upon request by Borrowers, such Letter of Credit Obligations shall be immediately paid by Borrowers pursuant to a Revolving Loan in the amount of such Letter of Credit Obligations.  Such Letter of Credit Obligations shall be immediately converted to a Revolving Loan by Bank and shall be evidenced by the Revolving Note.  If at any time any Event of Default occurs and any portion of any Letter of Credit remains unfunded, Borrowers shall pay to Bank in cash for application to future drawings under the outstanding Letters of Credit, an amount equal to the aggregate unfunded portion of the outstanding Letters of Credit.  If Borrowers do not pay such amount on demand, such amount shall be immediately paid by Borrowers by a Revolving Loan to Borrowers from Bank.  Such amount shall be immediately converted to a Revolving Loan by Bank and shall be evidenced by the Revolving Note.  The amount of such Revolving Loan shall be held by Bank in pledge securing Borrowers' obligations under this Agreement, with Borrowers hereby granting Bank a continuing security interest in such funds as security for the Indebtedness until Bank's obligation to make Revolving Loans has terminated, all Indebtedness has been paid in full, and no further Letters of Credit are outstanding.

ARTICLE IV

CERTAIN GENERAL PROVISIONS

Section 4.1.  Payments to Bank.  All payments of principal, interest, commitment fees and any other amounts due hereunder or under any of the other Related Documents shall be made to the Bank at the Bank's office at 313 Carondelet Street, New Orleans, Louisiana 70130, or at such other location that the Bank may from time to time designate in writing to Borrowers, in each case in immediately available funds.

Section 4.2.  No Offset, etc.  All payments by Borrowers hereunder and under any of the other Related Documents shall be made without setoff or counterclaim and free and clear of and without deduction for any taxes, levies, imposts, duties, charges, fees, deductions, withholdings, compulsory loans, restrictions or conditions of any nature now or hereafter imposed or levied by any jurisdiction or any political subdivision thereof or taxing or other authority therein unless Borrowers are compelled by law to make such deduction or withholding.  If any such obligation is imposed upon Borrowers with respect to any amount payable by them hereunder or under any of the other Loan Documents, Borrowers will pay to the Bank, on the date on which such amount is due and payable hereunder or under such other Related Document, such additional amount as shall be necessary to enable the Bank to receive the same net amount which Bank would have received on such due date had no such obligation been imposed upon Borrowers.  Borrowers will deliver promptly to the Bank certificates or other valid vouchers for all taxes or other charges deducted from or paid with respect to payments made by Borrowers hereunder or under such other Loan Documents.

Section 4.3.  Computations.  All computations of interest on the Revolving Loans and of commitment or other fees shall be assessed utilizing a 360-day daily interest factor over the number of days in an actual calendar year (365 days or 366 days in a leap year).  Bank shall determine each interest rate applicable to the Revolving Loans in accordance with this Agreement, and Bank's determination of same shall be conclusive in the absence of manifest error.  Except as otherwise provided herein, whenever a payment hereunder or under any of the other Related Documents becomes due on a day that is not a Business Day, the due date for such payment shall be extended to the next succeeding Business Day, and interest shall accrue during such extension.  The outstanding amount of the Revolving Loans as reflected on the Bank's books and records from time to time shall be prima facie evidence of the amounts so outstanding.

Section 4.4.  Additional Costs, etc.  If any present or future applicable law, which expression, as used herein, includes statutes, rules and regulations thereunder and interpretations thereof by any competent court or by any governmental or other regulatory body or official charged with the administration or the interpretation thereof and requests, directives, instructions and notices at any time or from time to time hereafter made upon or otherwise issued to the Bank by any central bank or other fiscal, monetary or other authority (whether or not having the force of law), shall:

(a)     subject the Bank to any tax, levy, impost, duty, charge, fee, deduction or withholding of any nature with respect to this Agreement, the other Related Documents or the Indebtedness (other than taxes based upon or measured by the revenue, income or profits of the Bank), or

(b)     materially change the basis of taxation (except for changes in taxes on revenue, income or profits) of payments to the Bank of the principal of or the interest on the Indebtedness of any other amounts payable to the Bank under this Agreement or the other Related Documents, or

(c)     impose or increase or render applicable (other than to the extent specifically provided for elsewhere in this Agreement) any special deposit, reserve, assessment, liquidity, capital adequacy or other similar requirements (whether or not having the force of law) against assets held by, or deposits in or for the account of, or loans by, or commitments of an office of the Bank, or

(d)     impose on the Bank any other conditions or requirements with respect to this Loan Agreement, the other Related Documents, the Indebtedness, or any class of loans of which the Indebtedness forms a part, and the result of any of the foregoing is:

(i)     to increase the cost to the Bank of making, funding, issuing, renewing, extending or maintaining the Indebtedness, or

(ii)     to reduce the amount of principal, interest or other amount payable to the Bank hereunder on account of such the Indebtedness, or

(iii)     to require the Bank to make any payment or to forego any interest or other sum payable hereunder, the amount of which payment or foregone interest or other sum is calculated by reference to the gross amount of any sum receivable or deemed received by the Bank from Borrowers hereunder,

then, and in each such case, Borrowers will, upon demand made by the Bank at any time and from time to time and as often as the occasion therefor may arise, pay to the Bank such additional amounts as will be sufficient to compensate the Bank for such additional cost, reduction, payment or foregoing receipt of interest or others sum payable hereunder.

Section 4.5.  Capital Adequacy.  If after the date hereof the Bank reasonably determines that (a) the adoption of or change in any law, governmental rule, regulations, policy guideline or directive (whether or not having the force of law) regarding capital requirements for banks or bank holding companies or any change in the interpretation or application thereof by a court or governmental authority with appropriate jurisdiction, or (b) compliance by the Bank or any corporation controlling the Bank with any law, governmental rule, regulation, policy, guideline or directive (whether or not having the force of law) of any such entity regarding capital adequacy, has the effect of reducing the return on the Bank's Revolving Loans to a level below that which the Bank could have achieved but for such adoption, change or compliance (taking into consideration the Bank's then existing policies with respect to capital adequacy and assuming full utilization of such entity's capital) by any amount deemed by the Bank to be material, then the Bank may notify Borrowers of such fact.  Borrowers agree to pay the Bank for the amount of such reduction in the return on capital as and when such reduction is determined upon presentation by the Bank of a certification in accordance with paragraph Section 4.6.

Section 4.6.  Certificate; Optional Right of Prepayment.  Bank shall provide Borrowers with a certificate setting forth any additional amounts which it declares to be payable pursuant to Sections 4.4 and 4.5 hereof, and a complete explanation of such amounts which are due, and each such certificate shall be conclusive, absent manifest error, that such amounts are due and owing.  Borrowers shall have the right, at any time within 90 days of receipt of any such certificate, to terminate this Agreement and prepay all the Revolving Loans (subject to any and all prepayment penalties, if any, under the terms of this Agreement) without being obligated to pay any such additional costs set forth in such certificate, after which (provided no Letters of Credit shall remain outstanding) Bank shall promptly terminate, discharge and release of record (at Borrowers' expense) all of its Encumbrances affecting the Collateral and return all Collateral to Borrowers.

Section 4.7.  Fees for the Revolving Loans.  In addition to the other fees and expenses described in Sections 3.3, 3.4 and 11.4 hereof, the Borrowers have paid or shall pay Bank the following fees:

(a)     Borrowers shall pay Bank upon the execution of this Agreement an origination fee in the amount of $13,840.00 for the increase in the amount of credit being made available from Bank pursuant to this Agreement, which fee has been fully earned by Bank upon the execution of this Agreement.

(b)     Borrowers shall pay Bank for the costs (including hourly rates of personnel and out-of-pocket expenses) of performing field examinations of the Collateral to be initially conducted on a quarterly basis, plus a monthly monitoring fee of $1,000.00 per month due at the beginning of each month during the term of this Agreement.

(c)     Borrowers shall pay to Bank an unused facility fee on the daily average unused portion of the Revolving Loan Commitment (the "unused portion" being the amount by which the maximum dollar amount of the Revolving Note ($8,883,997.00) exceeds the outstanding principal balance due under the Revolving Note plus the combined amount of all Letters of Credit outstanding) from the date of this Agreement through the Termination Date, at the rate of  0.375% per annum, payable for each three (3) calendar month period (each calendar quarter) (or portion thereof for the period ending 12/31/01), in arrears, fifteen (15) days after last day of each calendar quarter.

(d)     The following prepayment penalties shall be immediately due and payable by Borrowers to Bank if Borrowers shall terminate or refinance the Revolving Loans with another financial institution prior to the Termination Date:  (i) 2% of the amount of the outstanding Revolving Loans prepaid upon the refinancing of the Revolving Loans or the termination of this Agreement prior to December 31, 2001; and (ii) 1% of the amount of the outstanding Revolving Loans prepaid upon the refinancing of the Revolving Loans or the termination of this Agreement prior to December 31, 2002.  No prepayment penalty shall apply if Borrowers terminate this Agreement or refinance the Revolving Loans with another financial institution after December 31, 2002.

REPRESENTATIONS AND WARRANTIES

Borrowers represent and warrant to Bank as follows:

Section 7.1.  Corporate Authority.  Compressco is a corporation duly created, validly existing and in good standing under the laws of the State of Delaware, and is duly qualified and in good standing as a foreign corporation in all other jurisdictions where the failure to qualify would have an adverse effect upon its ability to perform its obligations under this Agreement and all Related Documents.  Field Services is a corporation duly created, validly existing and in good standing under the laws of the State of Oklahoma, and is duly qualified and in good standing as a foreign corporation in all other jurisdictions where the failure to qualify would have an adverse effect upon its ability to perform its obligations under this Agreement and all Related Documents.  Borrowers have the power to enter into this Agreement, issue the Revolving Note, mortgage and grant security interests in the Collateral in the manner and for the purpose contemplated by the Collateral Documents.  Borrowers have the corporate power to perform their obligations hereunder and under this Agreement and of the Related Documents.  The making and performance by Borrowers of this Agreement and of the Related Documents have been duly authorized by all necessary corporate action (including all necessary shareholder action), and do not and will not violate any provision of any law, rule, regulation, order, writ, judgment, decree, determination or award presently in effect having applicability to Borrowers or the articles of incorporation of Borrowers.  The making and performance by Borrowers of this Agreement and the Related Documents do not and will not result in a breach of or constitute a default under any indenture or loan or credit agreement or any other agreement or instrument to which either Borrower is a party or by which it may be bound or affected, or result in, or require, the creation or imposition of any mortgage, deed of trust, pledge, lien, security interest or other charge or encumbrance of any nature (other than as contemplated this Agreement and by the Related Documents) upon or with respect to any of the properties now owned or hereafter acquired by such Borrower, and neither Borrower is in default under or in violation of any such order, writ, judgment, decree, determination, award, indenture, agreement or instrument.  This Agreement and each of the Related Documents to which either Borrower is a party constitutes legal, valid and binding obligations of each such Borrower, enforceable in accordance with its terms, except to the extent that the enforceability of such instruments may be subject to the effect of applicable bankruptcy, insolvency, reorganization, moratorium or similar laws affecting creditors' rights generally, or the effect of general equity principles.

Section 7.2.  Financial Statements.  The balance sheet of Borrowers at the date thereof, and the related statements of income and retained earnings for the periods covered thereby, copies of which have been delivered to Bank, are complete and correct and fairly present the financial condition of Borrowers as of the date or dates thereof.

No Material Adverse Change has occurred since said dates in the financial position or in the results of operations of Borrowers in their businesses taken as a whole.

Section 7.3.  Title to Collateral.  Each Borrower has good and indefeasible title to the Collateral in which it has or shall grant Bank an Encumbrance as security for the Indebtedness, free and clear of all Encumbrances other than Permitted Encumbrances.  The Collateral Documents constitute legal, valid and perfected first Encumbrances on the property interests covered thereby, subject only to Permitted Encumbrances.

Section 7.4.  Litigation.  Other than as has been disclosed previously to Bank in writing, there are no material legal actions, suits or proceedings pending or, to the best of each Borrower's knowledge, threatened against or affecting such Borrower or any of its properties before any court or administrative agency (federal, state or local), which, if determined adversely to such Borrower, would constitute a Material Adverse Change, and there are no judgments or decrees affecting Borrowers or their properties (including, without limitation, the Collateral) which are or may become an Encumbrance against such properties.

Section 7.5.  Approvals.  No authorization, consent, approval or formal exemption of, nor any filing or registration with, any governmental body or regulatory authority (federal, state or local), and no vote, consent or approval of the shareholders of Borrowers is or will be required in connection with the execution and delivery by Borrowers of the Related Documents or the performance by Borrowers of their obligations hereunder and under the other Related Documents.

Section 7.6.  Licenses.  Each Borrower possesses adequate franchises, licenses and permits to own its properties and to carry on its business as presently conducted.

Section 7.7.  Adverse Agreements.  Neither Borrower is a party to any agreement or instrument, or subject to any charter or other restriction, materially and adversely affecting its business, properties, assets, or operations or its condition (financial or otherwise), and neither Borrower is in default in the performance, observance or fulfillment of any of the obligations, covenants or conditions contained in any agreement or instrument to which it is a party, which default would constitute a Material Adverse Change.

Section 7.8.  Default or Event of Default.  No Default or Event of Default hereunder has occurred or is continuing or will occur as a result of the giving effect hereto.

Section 7.9.  Employee Benefit Plans.  Each employee benefit plan as to which Borrowers may have any liability complies in all material respects with all applicable requirements of law and regulations, and (i) no Reportable Event (as defined in ERISA) has occurred with respect to any such plan, (ii) neither Borrower has withdrawn from any such plan or initiated steps to do so, and (iii) no steps have been taken to terminate any such plan.

Section 7.10.  Investment Company Act.  Neither Borrower is an "investment company" or a company "controlled" by an "investment company," within the meaning of the Investment Company Act of 1940, as amended.

Section 7.11.  Public Utility Holding Company Act.  Neither Borrower is a "holding company," or a "subsidiary company" of a "holding company," within the meaning of the Public Utility Holding Company Act of 1935, as amended.

Section 7.12.  Regulations X, T and U.  Neither Borrower is engaged principally, or as one of its important activities, in the business of extending credit for the purpose of purchasing or carrying margin stock (within the meaning of Regulations X, T and U of the Board of Governors of the Federal Reserve System), and none of the proceeds of the Revolving Loans will be used for the purpose of purchasing or carrying such margin stock.
