The Commitments of the Lenders to make the Loans shall be terminable by the Borrower by notice to the Agent at any time prior to April 28, 1995; provided, however, all fees accrued pursuant to Section 2.14 shall be paid by the Borrower and such Commitments may not thereafter be reinstated. (b) Subject to the terms of this Agreement, at any time prior to Final Maturity, the Borrower may convert Loans of one type or with one Interest Period into Loans of another type or with a different Interest Period. Each conversion of Loans shall be in an amount at least equal to $500,000. Each conversion of or into a Loan of a different type or, in the case of a LIBO Rate Loan, having a different Interest Period, shall be deemed a separate conversion for purposes of the foregoing, one for each type of Loan or Interest Period. Anything in this Agreement to the contrary notwithstanding, the aggregate principal amount of LIBO Rate Loans having the same Interest Period shall be at least equal to $1,000,000; and if any LIBO Rate Loan would otherwise be in a lesser principal amount for any period, such Loan shall be a Floating Rate Loan during such period. (c) Not later than 3:00 p.m., Central Standard or Daylight Savings Time, as the case may be, on the date specified for the borrowing under this Section, each Lender shall make available an amount equal to its Term Loan Commitment Amount to the Agent, at an account designated by the Agent, in immediately available funds, for the account of the Borrower. The amount so received by the Agent shall, subject to the terms and conditions hereof, be made available to the Borrower in immediately available funds at the Principal Office. All Loans by each Lender shall be maintained at the Applicable Lending Office of such Lender and shall be evidenced by the Note of such Lender. (d) The failure of any Lender to make the Loan required to be made by it hereunder shall not relieve any other Lender of its obligation to make the Loan required to be made by it, and no Lender shall be responsible for the failure of any other Lender to make any Loan. 2.2 Letter of Credit Facility. (a) Upon the terms and conditions and relying on the representations and warranties contained in this Agreement, the Agent, as issuing bank for the Lenders, agrees, during the Commitment Period, to issue, on behalf of the Lenders in their respective L/C Percentage Shares, Letters of Credit for the account of the Borrower and to renew and extend such Letters of Credit. Letters of Credit shall be issued, renewed, or extended from time to time on any Business Day designated by the Borrower following the receipt in accordance with the terms hereof by the Agent of the written (or oral, confirmed promptly in writing) request by a Responsible Officer of the Borrower therefor and a Letter of Credit Application.

Upon delivery by such Lender of funds requested pursuant to Section 2.2(c), such Lender shall be treated as having purchased a participating interest in an amount equal to such funds delivered by such Lender to the Agent in the obligation of the Borrower to reimburse the Agent, as the issuer of such Letter of Credit, for any amounts payable, paid, or incurred by the Agent, as the issuer of such Letter of Credit, with respect to such Letter of Credit. (c) Each Lender shall be unconditionally and irrevocably liable, without regard to the occurrence of any Default or Event of Default, to the extent of the L/C Percentage Share of such Lender at the time of issuance (or, with respect to the Existing Letters of Credit, on the Closing Date) of each Letter of Credit, to reimburse, on demand, the Agent, as the issuer of such Letter of Credit, for the amount of each Letter of Credit Payment under such Letter of Credit. Each Letter of Credit Payment shall be deemed to be a Floating Rate Loan by each Lender to the extent of funds delivered by such Lender to the Agent with respect to such Letter of Credit Payment and shall to such extent be deemed a Floating Rate Loan under and shall be evidenced by the Note of such Lender and shall be payable by the Borrower upon demand by the Agent. (d) EACH LENDER AGREES TO INDEMNIFY THE AGENT, AS THE ISSUER OF EACH LETTER OF CREDIT, AND THE OFFICERS, DIRECTORS, EMPLOYEES, AGENTS, ATTORNEYS- IN-FACT AND AFFILIATES OF THE AGENT (TO THE EXTENT NOT REIMBURSED BY THE BORROWER AND WITHOUT LIMITiNG THE OBLIGATION OF THE BORROWER TO DO SO), RATABLY ACCORDING TO THE L/C PERCENTAGE SHARE OF SUCH LENDER AT THE TIME OF ISSUANCE OF SUCH LETTER OF CREDIT, FROM AND AGAINST ANY AND ALL LIABILITIES, CLAIMS, OBLIGATIONS, LOSSES, DAMAGES, PENALTIES, ACTIONS, JUDGMENTS, SUITS, COSTS, EXPENSES AND DISBURSEMENTS OF ANY KIND WHATSOEVER WHICH MAY AT ANY TIME (INCLUDING, WITHOUT LIMITATION, ANY TIME FOLLOWING THE PAYMENT AND PERFORMANCE OF ALL OBLIGATIONS AND THE TERMINATION OF THIS AGREEMENT) BE IMPOSED ON, INCURRED BY OR ASSERTED AGAINST THE AGENT AS THE ISSUER OF SUCH LETTER OF CREDIT OR ANY OF ITS OFFICERS, DIRECTORS, EMPLOYEES, AGENTS, ATTORNEYS-IN-FACT OR AFFILIATES IN ANY WAY RELATING TO OR ARISING OUT OF THIS AGREEMENT OR SUCH LETTER OF CREDIT OR ANY ACTION TAKEN OR OMITTED BY THE AGENT AS THE ISSUER OF SUCH LETTER OF CREDIT OR ANY OF ITS OFFICERS, DIRECTORS, EMPLOYEES, AGENTS, ATTORNEYS-IN-FACT OR AFFILIATES UNDER OR IN CONNECTION WITH ANY OF THE FOREGOING, INCLUDING, WITHOUT LIMITATION, ANY LIABILITIES, CLAIMS, OBLIGATIONS, LOSSES, DAMAGES, PENALTIES, ACTIONS, JUDGMENTS, SUITS, COSTS, EXPENSES AND DISBURSEMENTS IMPOSED, INCURRED OR ASSERTED AS A RESULT OF THE NEGLIGENCE, WHETHER SOLE OR CONCURRENT, OF THE AGENT AS THE ISSUER OF SUCH LETTER OF CREDIT OR ANY OF ITS OFFICERS, DIRECTORS, EMPLOYEES, AGENTS, ATTORNEYS-IN-FACT OR AFFILIATES; PROVIDED THAT NO LENDER (OTHER THAN THE AGENT AS THE ISSUER OF A LETTER OF CREDIT) SHALL BE LIABLE FOR THE PAYMENT OF ANY PORTION OF SUCH LIABILITIES, OBLIGATIONS, LOSSES, DAMAGES, PENALTIES, ACTIONS, JUDGMENTS, SUITS, COSTS, EXPENSES OR DISBURSEMENTS RESULTING SOLELY FROM THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF THE AGENT AS THE ISSUER OF A LETTER OF CREDIT. THE AGREEMENTS IN THIS SECTION 2.2(d) SHALL SURVIVE THE PAYMENT AND PERFORMANCE OF ALL OBLIGATIONS AND THE TERMINATION OF THIS AGREEMENT. 2.3 Limitations on Interest Periods. Each Interest Period selected by the Borrower (a) which commences on the last Business Day of a calendar month (or any day for which there is no numerically corresponding day in the appropriate subsequent calendar month) shall end on the last Business Day of the appropriate subsequent calendar month, (b) which would otherwise end on a day which is not a Business Day shall end on the next succeeding Business Day (or, if such next succeeding Business Day falls in the next succeeding calendar month, on the next preceding Business Day), (c) which would otherwise end after Final Maturity shall end on Final Maturity, and (d) shall have a duration of not less than one month and, if any Interest Period would otherwise be a shorter period, the relevant Loan shall be a Floating Rate Loan during such period. 2.4 Limitation on Types of Loans. Anything herein to the contrary notwithstanding, no more than two separate Loans shall be outstanding at any one time, with, for purposes of this Section, all Floating Rate Loans constituting one Loan, and all LIBO Rate Loans for the same Interest Period constituting one Loan. Anything herein to the contrary notwithstanding, if, on or prior to the determination of any interest rate for any LIBO Rate Loan for any Interest Period therefor: (a) the Agent determines (which determination shall be conclusive, absent manifest error) that quotations of interest rates for the deposits referred to in the definition of "LIBO Rate" in Section 1.2 are not being provided in the relevant amounts or for the relevant maturities for purposes of determining the rate of interest for such Loan as provided in this Agreement; or (b) the Agent determines (which determination shall be conclusive, absent manifest error) that the rates of interest referred to in the definition of "LIBO Rate" in Section 1.2 upon the basis of which the rate of interest for such Loan for such Interest Period is to be determined do not accurately reflect the cost to the Lenders of making or maintaining such Loan for such Interest Period, then the Agent shall give the Borrower and the Lenders prompt notice thereof (which notice shall be deemed rebuttably presumptive evidence of the conditions set forth therein); and so long as such condition remains in effect, the Lenders shall be under no obligation to make LIBO Rate Loans or to convert Floating Rate Loans into LIBO Rate Loans, and the Borrower shall, on the last day of the then current Interest Period for each outstanding LIBO Rate Loan, either prepay such LIBO Rate Loan or convert such Loan into a Floating Rate Loan in accordance with Section 2.13. Before giving such notice pursuant to this Section, the Agent will take such action as the Borrower may request if such action will avoid the need to suspend the obligation of the Lenders to make LIBO Rate Loans hereunder and will not, in the opinion of the Agent, be disadvantageous to the Lenders. 2.5 Use of Loan Proceeds and Letters of Credit. (a) Proceeds of the Loans shall be used solely for the purchase by the Borrower of certain of the Pipeline Properties and to make loans to the Pipeline Subsidiaries for their purchase of the remaining Pipeline Properties. (b) Letters of Credit shall be used solely to support crude oil purchases by the Borrower. 2.6 Interest. (a) Subject to the terms of this Agreement (including, without limitation, Section 2.20), interest on the Loans shall accrue and be payable at a rate per annum equal to the Floating Rate for each Floating Rate Loan and the Adjusted LIBO Rate for each LIBO Rate Loan. Notwithstanding the foregoing, interest on past-due principal and, to the extent permitted by applicable law, past-due interest, shall accrue at the Default Rate and shall be payable upon demand by the Agent at any time as to all or any portion of such interest. In the event that the Borrower fails to select the duration of any Interest Period for any LIBO Rate Loan within the time period and otherwise as provided herein, such Loan (if outstanding as a LIBO Rate Loan) will be automatically converted into a Floating Rate Loan on the last day of the then current Interest Period for such Loan or (if outstanding as a Floating Rate Loan) will remain as, or (if not then outstanding) will be made as, a Floating Rate Loan. Interest provided for herein shall be calculated on unpaid sums actually advanced and outstanding pursuant to the terms of this Agreement and only for the period from the date or dates of such advances until repayment. (b) In the event the ratio of Total Debt to Capitalization as of the end of any fiscal quarter of Howell Corporation is less than or equal to .5 to 1.0, the Borrower and Howell Corporation may give notice, in the form of Exhibit VIII, of such fact to the Agent. On the Business Day following the receipt by the Agent of such notice, the Applicable Margin shall be reduced to one and one-half percent (1-1/2%). If, at any time thereafter, the ratio of Total Debt to Capitalization as of the end of any fiscal quarter of Howell Corporation is greater than .5 to 1.0, the Borrower and Howell Corporation shall give notice, in the form of Exhibit VIII, of such fact to the Agent. On the Business Day following the receipt by the Agent of such notice, the Applicable Margin shall be increased to two percent (2%) and thereafter shall not be subject to reduction as provided in the first sentence of this subsection until the ratio of Total Debt to Capitalization shall have been less than or equal to .5 to 1.0 for two successive fiscal quarters. 2.7 Repayment of Loans and Interest. (a) Accrued and unpaid interest on each outstanding Floating Rate Loan shall be due and payable monthly commencing on the first day of May, 1995, and continuing on the first day of each calendar month thereafter while any Floating Rate Loan remains outstanding, the payment in each instance to be the amount of interest which has accrued and remains unpaid in respect of the relevant Loan. Accrued and unpaid interest on each outstanding LIBO Rate Loan shall be due and payable on the last day of the Interest Period for such LIBO Rate Loan and, in the case of any Interest Period in excess of three months, on the day of the third calendar month following the commencement of such Interest Period corresponding to the day of the calendar month on which such Interest Period commenced, the payment in each instance to be the amount of interest which has accrued and remains unpaid in respect of the relevant Loan. (b) The Loan Balance shall be due and payable in quarterly installments commencing on the first day of July, 1995, and continuing thereafter on the first day of each third calendar month until Final Maturity. Such installments shall be in the amount of the lesser of the Loan Balance or One Million Four Hundred Thirty-Seven Thousand Five Hundred Dollars ($1,437,500). The Loan Balance, together with all accrued and unpaid interest thereon, shall be due and payable at Final Maturity. (c) At the time of making each payment hereunder or under the Notes, the Borrower shall specify to the Agent the Loans or other amounts payable by the Borrower hereunder to which such payment is to be applied. In the event the Borrower fails to so specify, or if an Event of Default has occurred and is continuing, the Agent may apply such payment as it may elect in its discretion and in accordance with the terms hereof. 2.8 General Terms. (a) The outstanding principal balance of the Note of each Lender reflected in the records of such Lender shall be deemed rebuttably presumptive evidence of the principal amount owing on such Note. The liability for payment of principal and interest evidenced by each Note shall be limited to principal amounts actually advanced and outstanding pursuant to this Agreement and interest on such amounts calculated in accordance with this Agreement. (b) Unless the Agent shall have been notified by a Lender or the Borrower prior to the date on which either of them is scheduled to make payment to the Agent of (in the case of a Lender) the proceeds of a Loan to be made by such Lender hereunder or (in the case of the Borrower) a payment to the Agent for account of one or more of the Lenders hereunder (such payment being herein called the "Required Payment"), which notice shall be effective upon receipt, that such Lender or the Borrower, as the case may be, does not intend to make the Required Payment to the Agent, the Agent may assume that the Required Payment has been made and, in reliance upon such assumption, may (but shall not be required to) make the amount thereof available to the intended recipient on such date. If such Lender or the Borrower, as the case may be, has not in fact made the Required Payment to the Agent, the recipient of such payment shall, on demand, repay to the Agent for its account the amount so made available together with interest thereon in respect of each day during the period commencing on the date such amount was so made available by the Agent until the date the Agent recovers such amount at a rate per annum equal to, in the case of a Lender as recipient, the Federal Funds Rate or, in the case of the Borrower as recipient, the Floating Rate. 2.9 Time, Place, and Method of Payments. All payments required pursuant to this Agreement or the Notes shall be made without set-off or counterclaim in Dollars and in immediately available funds. All payments by the Borrower shall be deemed received on the next Business Day following receipt if such receipt is after 5:00 p.m., Central Standard or Daylight Savings Time, as the case may be, on any Business Day, and shall be made to the Agent at the Principal Office. Except as provided to the contrary herein, if the due date of any payment hereunder or under any Note would otherwise fall on a day which is not a Business Day, such date shall be extended to the next succeeding Business Day, and interest shall be payable for any principal so extended for the period of such extension. 2.10 Pro Rata Treatment; Adjustments. (a) Except to the extent otherwise expressly provided herein, (i) the borrowing made pursuant to this Agreement shall be from the Lenders pro rata in accordance with their respective Term Loan Percentage Shares, (ii) each payment by the Borrower of fees shall be made for the account of the Lenders pro rata in accordance with their respective Term Loan Percentage Shares, (iii) each payment of principal of Loans shall be made for the account of the Lenders pro rata in accordance with their respective shares of the Loan Balance, and (iv) each payment of interest on Loans shall be made for the account of the Lenders pro rata in accordance with their respective shares of the aggregate amount of interest due and payable to the Lenders. (b) The Agent shall distribute all payments with respect to the Obligations to the Lenders promptly upon receipt in like funds as received. In the event that any payments made hereunder by the Borrower at any particular time are insufficient to satisfy in full the Obligations due and payable at such time, such payments shall be applied (a) first, to fees and expenses due pursuant to the terms of this Agreement or any other Loan Document, (b) second, to accrued interest, (c) third, to the Loan Balance, and (d) last, to any other Obligations. (c) If any Lender (for purposes of this Section, a "benefitted Lender") shall at any time receive any payment of all or part of its portion of the Obligations, or receive any Collateral in respect thereof (whether voluntarily or involuntarily, by set-off, pursuant to events or proceedings of the nature referred to in Sections 7.1(e) or 7.1(f), or otherwise) in an amount greater than such Lender was entitled to receive pursuant to the terms hereof, such benefitted Lender shall purchase for cash from the other Lenders such portion of the Obligations of such other Lenders or shall provide such other Lenders with the benefits of any such Collateral or the proceeds thereof as shall be necessary to cause such benefitted Lender to share the excess payment or benefits of such Collateral or proceeds with each of the Lenders according to the terms hereof. If all or any portion of such excess payment or benefits is thereafter recovered from such benefitted Lender, such purchase shall be rescinded and the purchase price and benefits returned by such Lender, to the extent of such recovery, but without interest. The Borrower agrees that each such Lender so purchasing a portion of the Obligations of another Lender may exercise all rights of payment (including, without limitation, rights of set- off) with respect to such portion as fully as if such Lender were the direct holder of such portion. If any Lender ever receives, by voluntary payment, exercise of rights of set-off or banker's lien, counterclaim, cross-action or otherwise, any funds of the Borrower to be applied to the Obligations, or receives any proceeds by realization on or with respect to any Collateral, all such funds and proceeds shall be immediately forwarded to the Agent for distribution in accordance with the terms of this Agreement. 2.11 Borrowing Base Determinations. (a) The Borrowing Base as of the Closing Date is acknowledged by the Borrower and the Lenders to be $16,326,546.80. (b) The Borrowing Base shall be redetermined monthly upon receipt by the Lenders of each Borrowing Base Report and Receivable Report required pursuant to Section 5.4 and shall be the amount set forth as the Borrowing Base in such Borrowing Base Report unless any Lender advises the Agent and the Borrower that such Lender does not agree with the amount set forth as the Borrowing Base in such Borrowing Base Report. In such event, the Borrowing Base in effect prior to the receipt of such Borrowing Base Report shall be in effect until the Lenders shall have redetermined the Borrowing Base and advised the Borrower thereof. Notwithstanding the foregoing, at the request of any Lender, the Lenders may at their discretion redetermine the Borrowing Base at any time and from time to time. (c) The Borrowing Base shall represent the determination by the Lenders, in accordance with the applicable definitions and provisions herein contained and their customary lending practices for loans of this nature, of the value, for loan purposes, of the Eligible Accounts. Furthermore, the Borrower acknowledges that the determination of the Borrowing Base contains an equity cushion (market value in excess of loan value), which is acknowledged by the Borrower to be essential for the adequate protection of the Lenders. 2.12 Mandatory Prepayments; Cash Collateral. (a) In addition to the payments on the Notes required pursuant to Section 2.7, beginning with the delivery of Financial Statements for the fiscal quarter ending March 31, 1996, on each date on which Financial Statements are required to be delivered to the Agent and the Lenders pursuant to Sections 5.2 and 5.3 (or on the date such Financial Statements are delivered, if earlier), the Borrower shall pay an amount equal to 60% of Excess Cash Flow for the previous fiscal quarter for application as a prepayment on the Notes. (b) If at any time the L/C Exposure exceeds the lesser of the Maximum L/C Commitment Amount or the Borrowing Base then in effect, the Borrower shall, within two days of notice from the Agent of such occurrence, deposit with the Agent, as additional collateral securing the Obligations, an amount of cash, in immediately available funds, equal to the L/C Exposure minus the lesser of the Maximum L/C Commitment Amount or the Borrowing Base. The cash deposited with the Agent in satisfaction of the requirement provided in this Section may be invested, at the sole discretion of the Agent and then only at the express direction of the Borrower as to investment vehicle and maturity (which shall be no later than the latest expiry date of any then outstanding Letter of Credit), for the account of the Borrower in cash or cash equivalent investments offered by or through Bank One. 2.13 Voluntary Prepayments and Conversions of Loans. Subject to applicable provisions of this Agreement, the Borrower shall have the right at any time or from time to time to prepay Loans and to convert Loans of one type or with one Interest Period into Loans of another type or with a different Interest Period; provided, however, that (a) the Borrower shall give the Agent notice of each such prepayment or conversion of all or any portion of a LIBO Rate Loan no less than two Business Days prior to prepayment or conversion, (b) any LIBO Rate Loan may be prepaid or converted only on the last day of an Interest Period for such Loan, (c) the Borrower shall pay all accrued and unpaid interest on the amounts of LIBO Rate Loans prepaid or converted, and (d) no such prepayment or conversion shall serve to postpone the repayment when due of any Obligation. 2.14 Commitment Fee. (a) To compensate the Lenders for maintaining funds available, the Borrower shall pay to the Agent for the account of the Lenders a fee in the amount of three-eighths of one percent (3/8%) per annum, calculated on the basis of a year of 365 or 366 days, as the case may be, and actual days elapsed (including the first day but excluding the last day), of the Maximum Term Loan Commitment Amount for the period beginning April 1, 1995, and ending on the earliest of the date the Loans are made, April 30, 1995, or the date on which the Borrower gives notice to the Agent that the Borrower wishes to terminate the Commitments to make Loans. Such accrued commitment fees shall be payable on the date of funding of the Loans pursuant to Section 2.1, April 30, 1995, or the date of such notice of termination by the Borrower, as the case may be. (b) The Borrower shall pay to the Agent for the account of the Lenders in accordance with their respective L/C Percentage Shares a letter of credit commitment fee in the amount of one-fourth of one percent (1/4%) per annum, calculated on the basis of a year of 365 or 366 days, as the case may be, and actual days elapsed (including the first day but excluding the last day), on the average daily amount of the Available L/C Commitment. Accrued letter of credit commitment fees shall be payable on the first day of July, 1995, the first day of each third calendar month thereafter during the Commitment Period (or within five days following the notice from the Agent of the amount of such fee owing, if later), and on the Commitment Termination Date. 2.15 Facility Fee. To compensate the Lenders for the extension of credit hereunder, the Borrower shall pay to the Agent for the account of the Lenders on the Closing Date a facility fee in accordance with the terms of the Facility Fee Letter. 2.16 Letter of Credit Fee. The Borrower shall pay to the Agent for the account of the Lenders in accordance with their respective L/C Percentage Shares, on the date of issuance or renewal of each Letter of Credit, an issuing fee equal to the greater of $500 or one percent (1%) per annum, calculated on the basis of a year of 365 or 366 days, as the case may be, and actual days elapsed (including the first day but excluding the last day), on the face amount of such Letter of Credit during the period for which such Letter of Credit is issued or renewed. The Borrower also agrees to pay on demand to the Agent for its own account as the issuer of the Letters of Credit its customary letter of credit transactional fees and expenses, including, without limitation, amendment fees, payable with respect to each Letter of Credit. 2.17 Agency Fee. The Borrower shall pay to the Agent for its own account all fees owing or which may become owing under the Agency Fee Letter as provided therein. 2.18 Loans to Satisfy Obligations of Borrower. The Lenders may, but shall not be obligated to, make Loans for the benefit of the Borrower and apply proceeds thereof to the satisfaction of any condition, warranty, representation, or covenant of the Borrower or any Guarantor contained in this Agreement or any other Loan Document. Such Loans shall be evidenced by the Notes, shall be made as a Floating Rate Loan, and shall be payable upon demand. The Agent agrees to notify the Borrower of any such Loan; provided, however, the failure of the Agent or any Lender to do so shall not subject the Agent or any Lender to any liability and shall not relieve the Borrower from liability for any Obligation. 2.19 Security Interest in Accounts; Right of Offset. As security for the payment and performance of the Obligations, the Borrower hereby transfers, assigns, and pledges to the Agent and each Lender and grants to the Agent and each Lender a security interest in all funds of the Borrower now or hereafter or from time to time on deposit with the Agent or such Lender, with such interest of the Agent and the Lenders to be retransferred, reassigned, and/or released, as the case may be, at the reasonable expense of the Borrower upon payment in full and complete performance of all Obligations and the termination of the Commitments. All remedies as secured party or assignee of such funds shall be exercisable by the Agent and the Lenders with the verbal consent (confirmed promptly in writing) of the Required Lenders upon the occurrence of any Event of Default, regardless of whether the exercise of any such remedy would result in any penalty or loss of interest or profit with respect to any withdrawal of funds deposited in a time deposit account prior to the maturity thereof. Furthermore, the Borrower hereby grants to the Agent and each Lender the right, exercisable at such time as any Event of Default shall occur, of offset or banker's lien against all funds of the Borrower now or hereafter or from time to time on deposit with the Agent or such Lender, regardless of whether the exercise of any such remedy would result in any penalty or loss of interest or profit with respect to any withdrawal of funds deposited in a time deposit account prior to the maturity thereof. 2.20 General Provisions Relating to Interest. (a) It is the intention of the parties hereto to comply strictly with all applicable usury laws. In this connection, there shall never be collected, charged, or received on the sums advanced hereunder interest in excess of that which would accrue at the Highest Lawful Rate. For purposes of Article 5069-1.04, Vernon's Texas Civil Statutes, as amended, the Borrower agrees that the Highest Lawful Rate shall be the "indicated (weekly) rate ceiling" as defined in such Article, provided that the Agent and the Lenders may also rely, to the extent permitted by applicable laws, on alternative maximum rates of interest under other laws, if greater. (b) Notwithstanding anything herein or in the Notes to the contrary, during any Limitation Period, the interest rate to be charged on amounts evidenced by the Notes shall be the Highest Lawful Rate, and the obligation, if any, of the Borrower for the payment of fees or other charges deemed to be interest under applicable law shall be suspended. During any period or periods of time following a Limitation Period, to the extent permitted by applicable laws, the interest rate to be charged hereunder shall remain at the Highest Lawful Rate until such time as there has been paid to the Agent and each Lender (i) the amount of interest in excess of that accruing at the Highest Lawful Rate that such Lender would have received during the Limitation Period had the interest rate remained at the otherwise applicable rate, and (ii) all interest and fees otherwise payable to the Agent and such Lender but for the effect of such Limitation Period. (c) If, under any circumstances, the aggregate amounts paid on the Notes or under this Agreement or any other Loan Document include amounts which by law are deemed interest and which would exceed the amount permitted if the Highest Lawful Rate were in effect, the Borrower stipulates that such payment and collection will have been and will be deemed to have been, to the extent permitted by applicable laws, the result of mathematical error on the part of the Borrower, the Agent, and the Lenders; and the party receiving such excess shall promptly refund the amount of such excess (to the extent only of such interest payments in excess of that which would have accrued and been payable on the basis of the Highest Lawful Rate) upon discovery of such error by such party or notice thereof from the Borrower. In the event that the maturity of any Obligation is accelerated, by reason of an election by the Lenders or otherwise, or in the event of any required or permitted prepayment, then the consideration constituting interest under applicable laws may never exceed the Highest Lawful Rate; and excess amounts paid which by law are deemed interest, if any, shall be credited by the Agent and the Lenders on the principal amount of the Obligations, or if the principal amount of the Obligations shall have been paid in full, refunded to the Borrower. (d) All sums paid, or agreed to be paid, to the Agent and the Lenders for the use, forbearance and detention of the proceeds of any advance hereunder shall, to the extent permitted by applicable law, be amortized, prorated, allocated, and spread throughout the full term hereof until paid in full so that the actual rate of interest is uniform but does not exceed the Highest Lawful Rate throughout the full term hereof. 2.21 Obligations Absolute. Subject to the further provisions of this Section, the Obligations of the Borrower under this Article shall be absolute and unconditional under any and all circumstances and irrespective of any set-off, counterclaim, or defense to payment or performance which the Borrower may have or have had against the Agent, any Lender, or any beneficiary of any Letter of Credit. The Borrower agrees that none of the Agent or the Lenders shall be responsible for, nor shall the Obligations be affected by, among other things, (a) the validity or genuineness of documents or any endorsements thereon presented in connection with any Letter of Credit, even if such documents shall in fact prove to be in any and all respects invalid, fraudulent or forged, AND EVEN IF DUE TO THE NEGLIGENCE, WHETHER SOLE OR CONCURRENT, OF THE AGENT OR ANY LENDER, so long as the Agent, as the issuer of such Letter of Credit, has no actual knowledge of any such invalidity, lack of genuineness, fraud, or forgery prior to the presentment for payment of a corresponding Letter of Credit or any draft thereunder; provided, however, with respect to the preceding matters in this Section, the Agent, as the issuer of the Letters of Credit, agrees to exercise ordinary care in examining each document required to be presented pursuant to each Letter of Credit to ascertain that each such document appears on its face to comply with the terms thereof, or (b) any dispute between or among the Borrower and any beneficiary of any Letter of Credit or any other party to which any Letter of Credit may be transferred, or any claims whatsoever of the Borrower against any beneficiary of any Letter of Credit or any such transferee, EVEN IF DUE TO THE NEGLIGENCE, WHETHER SOLE OR CONCURRENT, OF THE AGENT OR ANY LENDER; provided, in all respects, that the Agent, as the issuer of Letters of Credit, shall be liable to the Borrower to the extent, but only to the extent, of any direct, as opposed to consequential or punitive, damages suffered by the Borrower as a result of the willful misconduct or gross negligence of the Agent as the issuer of Letters of Credit in determining whether documents presented under a Letter of Credit complied with the terms of such Letter of Credit that resulted in either a wrongful payment under such Letter of Credit or a wrongful dishonor of a claim or draft properly presented under such Letter of Credit. In the absence of gross negligence or willful misconduct by the Agent as the issuer of Letters of Credit, the Agent shall not be liable for any error, omission, interruption or delay, EVEN IF DUE TO THE NEGLIGENCE, WHETHER SOLE OR CONCURRENT, OF THE AGENT, in transmission, dispatch or delivery of any message or advice, however transmitted, in connection with any Letter of Credit. The Agent, the Lenders, and the Borrower agree that any action taken or omitted by the Agent, as issuer of any Letter of Credit, under or in connection with any Letter of Credit or the related drafts or documents, EVEN IF DUE TO THE NEGLIGENCE, WHETHER SOLE OR CONCURRENT, OF THE AGENT OR ANY LENDER, if done in the absence of gross negligence or willful misconduct, shall be binding as among the Agent, as issuer of such Letter of Credit or otherwise, the Lenders, and the Borrower and shall not put the Agent, as issuer of such Letter of Credit or otherwise, or any Lender under any liability to the Borrower. 2.22 Yield Protection. (a) Without limiting the effect of the other provisions of this Section (but without duplication), the Borrower shall pay to the Agent and each Lender from time to time such amounts as the Agent or such Lender may determine are necessary to compensate it for any Additional Costs incurred by the Agent or such Lender. (b) Without limiting the effect of the other provisions of this Section (but without duplication), the Borrower shall pay to each Lender from time to time on request such amounts as such Lender may determine are necessary to compensate such Lender for any costs attributable to the maintenance by such Lender (or any Applicable Lending Office), pursuant to any Regulatory Change, of capital in respect of its Commitment, such compensation to include, without limitation, an amount equal to any reduction of the rate of return on assets or equity of such Lender (or any Applicable Lending Office) to a level below that which such Lender (or any Applicable Lending Office) could have achieved but for such Regulatory Change. (c) Without limiting the effect of the other provisions of this Section (but without duplication), in the event that any Requirement of Law or Regulatory Change or the compliance by the Agent or any Lender therewith shall (i) impose, modify, or hold applicable any reserve, special deposit, or similar requirement against any Letter of Credit or obligation to issue Letters of Credit, or (ii) impose upon the Agent or such Lender any other condition regarding any Letter of Credit or obligation to issue Letters of Credit, and the result of any such event shall be to increase the cost to the Agent or such Lender of issuing or maintaining any Letter of Credit or obligation to issue Letters of Credit or any liability with respect to Letter of Credit Payments, or to reduce any amount receivable in connection therewith, then upon demand by the Agent or such Lender, as the case may be, the Borrower shall pay to the Agent or such Lender,from time to time as specified by the Agent or such Lender, additional amounts which shall be sufficient to compensate the Agent or such Lender for such increased cost or reduced amount receivable. (d) Without limiting the effect of the other provisions of this Section (but without duplication), the Borrower shall pay to the Agent and each Lender such amounts as shall be sufficient in the reasonable opinion of the Agent and such Lender to compensate them for any loss, cost, or expense incurred by and as a result of: (i) any payment, prepayment, or conversion by the Borrower of a LIBO Rate Loan on a date other than the last day of an Interest Period for such Loan; or (ii) any failure by the Borrower to borrow a LIBO Rate Loan or to convert a Floating Rate Loan into a LIBO Rate Loan on the date for such borrowing or conversion specified in the relevant Borrowing Request; such compensation to include, without limitation, with respect to any LIBO Rate Loan, an amount equal to the excess, if any, of (A) the amount of interest which would have accrued on the principal amount so paid, prepaid, converted, or not borrowed or converted for the period from the date of such payment, prepayment, conversion, or failure to borrow or convert to the last day of the then current Interest Period for such Loan (or, in the case of a failure to borrow or convert, the Interest Period for such Loan which would have commenced on the date of such failure to borrow or convert) at the applicable rate of interest for such Loan provided for herein over (B) the interest component of the amount the Agent or such Lender would have bid in the London interbank market for Dollar deposits of amounts comparable to such principal amount and maturities comparable to such period, as reasonably determined by the Agent or such Lender. (e) The Agent or such Lender shall determine for purposes of this Section the effect of any Regulatory Change on capital maintained, its costs or rate of return, maintaining Loans, issuing Letters of Credit, its obligation to make Loans and issue Letters of Credit, or on amounts receivable by it in respect of Loans, Letters of Credit, or such obligations, and the additional amounts required to compensate the Agent or such Lender under this Section and shall furnish the Borrower with a certificate setting forth in reasonable detail the basis and amount of increased costs incurred or reduced amounts receivable as a result of any such event. The statements set forth therein shall be deemed rebuttably presumptive evidence of such amount. The Agent or the relevant Lender shall notify the Borrower, as promptly as practicable after the Agent or such Lender obtains knowledge of any Additional Costs or other sums payable pursuant to this Section and determines to request compensation therefor, of any event occurring after the Closing Date which will entitle the Agent or such Lender to compensation pursuant to this Section. If any Lender requests compensation from the Borrower under this Section, the Borrower may, by notice to the Agent and such Lender, require that the Loans by the Lender of the type with respect to which such compensation is requested be converted into Floating Rate Loans in accordance with Section 2.13. Any compensation requested by the Agent or any Lender pursuant to this Section shall be due and payable to the Agent or such Lender within five days of delivery of any such notice to the Borrower. (f) The Agent and the Lenders agree not to request, and the Borrower shall not be obligated to pay, any Additional Costs or other sums payable pursuant to this Section unless similar additional costs and other sums payable are also generally assessed by the Agent or such Lender against other customers similarly situated where such customers are subject to documents providing for such assessment. 2.23 Illegality. Notwithstanding any other provision of this Agreement, in the event that it becomes unlawful for any Lender or its Applicable Lending Office to (a) honor its obligation to make LIBO Rate Loans, or (b) maintain LIBO Rate Loans, then such Lender shall promptly notify the Agent and the Borrower thereof. The obligation of such Lender to make LIBO Rate Loans and to convert Floating Rate Loans into LIBO Rate Loans shall then be suspended until such time as such Lender may again make and maintain LIBO Rate Loans, and the outstanding LIBO Rate Loans of such Lender shall be converted into Floating Rate Loans in accordance with Section 2.13. Before giving such notice pursuant to this Section, such Lender will take such action as the Borrower may request if such action will avoid the need to suspend the obligation of such Lender to make LIBO Rate Loans and will not, in the opinion of such Lender, be disadvantageous to such Lender. 2.24 Taxes. (a) All payments made by the Borrower under this Agreement shall be made free and clear of, and without reduction or withholding for or on account of, present or future income, stamp or other taxes, levies, imposts, duties, charges, fees, deductions or withholdings, hereafter imposed, levied, collected, withheld or assessed by any Governmental Authority on the basis of any change after the date hereof in any applicable treaty, law, rule, guideline or regulations or in the interpretation or administration thereof, excluding, in the case of the Agent and each Lender, net income and franchise taxes imposed on the Agent or such Lender by the jurisdiction under the laws of which the Agent or such Lender is organized or any political subdivision or taxing authority thereof or therein, or by any jurisdiction in which such Lender's lending office is located or any political subdivision or taxing authority thereof or therein (all such non-excluded taxes, levies, imposts, deductions, charges or withholdings being hereinafter called "Taxes"). If any Taxes are required to be withheld from any amounts payable to the Agent or any Lender hereunder or under any other Loan Document, the amounts so payable to the Agent or such Lender shall be increased to the extent necessary to yield to the Agent or such Lender (after payment of all Taxes) interest or any such other amounts payable hereunder at the rates or in the amounts specified in this Agreement and the other Loan Documents. The Agent or the relevant Lender shall, as promptly as practicable after becoming aware of any Taxes, notify the Borrower thereof; and notwithstanding the foregoing, unless such Taxes are made retroactive, the Borrower shall not be obligated for the payment of any Taxes to the extent such Taxes accrued more than 150 days prior to the earlier of the date of such notice or the date on which the Borrower otherwise became aware that such Taxes were to be imposed. Whenever any Taxes are payable by the Borrower, as promptly as possible thereafter, the Borrower shall send to the Agent for its own account or for the account of such Lender, as the case may be, a certified copy of an original official receipt received by the Borrower showing payment thereof. If the Borrower fails to pay any Taxes when due to the appropriate taxing authority or fails to remit to the Agent the required receipts or other required documentary evidence, the Borrower shall indemnify the Agent and the Lenders for any incremental taxes, interest or penalties that may become payable by the Agent or any Lender as a result of any such failure. The agreements in this Section shall survive the termination of this Agreement and the payment of all Obligations. (b) Each Lender that is not incorporated under the laws of the United States of America or a state thereof agrees that, prior to the first date on which any payment is due to it hereunder, it will, to the extent it may lawfully do so, deliver to the Borrower and the Agent two duly completed copies of United States Internal Revenue Service Form 1001 or 4224 or successor applicable form, as the case may be, certifying in each case that such Lender is entitled to receive payments under this Agreement and the Note payable to it, without deduction or withholding of any United States federal income taxes. At the written request of the Borrower, each Lender which delivers to the Borrower and the Agent a Form 1001 or 4224 pursuant to the preceding sentence further undertakes to deliver to the Borrower and the Agent two further copies of such Form 1001 or 4224, or successor applicable forms, or other manner of certification, as the case may be, on or before the date that any such letter or form expires or becomes obsolete or after the occurrence of any event requiring a change in the most recent form previously delivered by it to the Borrower, and such extensions or renewals thereof as may reasonably be requested by the Borrower, certifying in the case of Form 1001 or 4224 that such Lender is entitled to receive payments under this Agreement without deduction or withholding of any United States federal income taxes, unless in any such case, an event (including, without limitation, any change in treaty, law or regulation) has occurred prior to the date on which any such delivery would otherwise be required which renders all such forms inapplicable or which would prevent such Lender from duly completing and delivering any such form with respect to it and such Lender advises the Borrower that it is not capable of receiving payments without any deduction or withholding of United States federal income tax. 2.25 Replacement Lenders. (a) If any Lender has notified the Borrower of its incurring additional costs under Section 2.22 or that, pursuant to Section 2.23 or 2.26, its obligation to make or maintain LIBO Rate Loans is to be suspended, or has required the Borrower to make payments for Taxes under Section 2.24, the Borrower may, unless such Lender has notified the Borrower that the circumstances giving rise to such notice no longer apply, terminate, in whole but not in part, the Commitment of any Lender (other than the Agent) (the "Terminated Lender") at any time upon five Business Days' prior written notice to the Terminated Lender and the Agent (such notice referred to herein as a "Notice of Termination"). (b) In order to effect the termination of the Commitment of the Terminated Lender, the Borrower shall (i) with the consent of Lenders holding at least seventy percent (70%) of the Loan Balance, without regard to any sale of a participation in any Loan and exclusive of the portion of the Loan Balance outstanding to the Terminated Lender, pay to the Agent for the account of the Terminated Lender only, all amounts owing to such Terminated Lender under the Loan Documents, or (ii) obtain an agreement with one or more Lenders to increase their Commitments and/or request any one or more other banking institutions to become a "Lender" in place and instead of such Terminated Lender and agree to accept a Commitment; provided, however, that such other banking institutions are reasonably acceptable to the Agent and become parties by executing an Assignment Agreement (the Lenders or other banking institutions that agree to accept in whole or in part the Commitment of the Terminated Lender being referred to herein as the "Replacement Lenders"), such that the aggregate increased and/or accepted L/C Commitment Amounts and Term Loan Commitment Amounts of the Replacement Lenders equal the L/C Commitment Amount and Term Loan Commitment Amount, respectively, of the Terminated Lender. (c) The Notice of Termination shall include the name of the Terminated Lender, the date the termination will occur (the "Termination Date"), the Replacement Lender or Replacement Lenders to which the Terminated Lender will assign its Commitment, and, if there will be more than one Replacement Lender, the portion of the Terminated Lender's Commitment to be assigned to each Replacement Lender. (d) On the Termination Date, (i) the Terminated Lender shall by execution and delivery of an Assignment Agreement assign its Commitment to the Replacement Lender or Replacement Lenders (pro rata, if there is more than one Replacement Lender, in proportion to the portion of the Terminated Lender's Commitment to be assigned to each Replacement Lender) indicated in the Notice of Termination and shall assign to the Replacement Lender or Replacement Lenders its Loan (if any) then outstanding pro rata as aforesaid), (ii) the Terminated Lender shall endorse its Note, payable without recourse, representation or warranty to the order of the Replacement Lender or Replacement Lenders (pro rata as aforesaid), (iii) the Replacement Lender or Replacement Lenders shall purchase the Note held by the Terminated Lender (pro rata as aforesaid) at a price equal to the unpaid principal amount thereof plus interest and fees accrued and unpaid to the Termination Date, and (iv) the Replacement Lender or Replacement Lenders will thereupon (pro rata as aforesaid) succeed to and be substituted in all respects for the Terminated Lender with like effect as if becoming a Lender pursuant to the terms of Section 9.1(b), and the Terminated Lender will have the rights and benefits of an assignor under Section 9.1(b). To the extent not in conflict, the terms of Section 9.1(b) shall supplement the provisions of this Section. 2.26 Regulatory Change. In the event that by reason of any Regulatory Change or any other circumstance arising after the Closing Date affecting any Lender, such Lender (a) incurs Additional Costs (other than those incurred as a result of an increase in the Reserve Requirement) based on or measured by the excess above a specified level of the amount of a category of deposits or other liabilities of such Lender which includes deposits by reference to which the interest rate on any LIBO Rate Loan is determined as provided in this Agreement or a category of extensions of credit or other assets of such Lender which includes any LIBO Rate Loan, or (b) becomes subject to restrictions on the amount of such a category of liabilities or assets which it may hold, then, at the election of such Lender with notice to the Agent and the Borrower, the obligation of such Lender to make LIBO Rate Loans and to convert Floating Rate Loans into LIBO Rate Loans shall be suspended until such time as such Regulatory Change or other circumstance ceases to be in effect, and all such outstanding LIBO Rate Loans shall be converted into Floating Rate Loans in accordance with Section 2.13. ARTICLE III CONDITIONS 3.1 Conditions Precedent to Loans. The Lenders shall have no obligation to make the Loans unless and until the following conditions precedent have been satisfied: (a) all matters incident to the consummation of the transactions contemplated herein, including, without limitation, the review by the Agent or its counsel of the title of the Borrower and/or the Pipeline Subsidiaries to their respective Mortgaged Properties, shall be satisfactory to the Agent;

ARTICLE IV REPRESENTATIONS AND WARRANTIES To induce the Agent and the Lenders to enter into this Agreement and to extend credit to the Borrower, the Borrower represents and warrants to the Agent and each Lender (which representations and warranties shall survive the delivery of the Notes) that: 4.1 Due Authorization. The execution and delivery by the Borrower of this Agreement and the borrowings hereunder, the execution and delivery by the Borrower of the Notes and the other Loan Documents, the repayment of the Notes and interest and fees provided for in the Notes and this Agreement, and the performance of all obligations of the Borrower under the Loan Documents are within the power of the Borrower, have been duly authorized by all necessary corporate action by the Borrower, and do not and will not (a) require the consent of any Governmental Authority, (b) contravene or conflict with any Requirement of Law, (c) contravene or conflict with any indenture, instrument, or other agreement to which the Borrower is a party or by which any Property of the Borrower may be presently bound or encumbered, or (d) result in or require the creation or imposition of any Lien in, upon or of any Property of the Borrower other than as contemplated by the Loan Documents. 4.2 Corporate Existence. The Borrower is a corporation duly organized, legally existing, and in good standing under the laws of its state of incorporation and is duly qualified as a foreign corporation and is in good standing in all jurisdictions wherein the ownership of Property or the operation of its business necessitates same, other than those jurisdictions wherein the failure to so qualify will not have a Material Adverse Effect. 4.3 Valid and Binding Obligations. All Loan Documents to which the Borrower is a party, when duly executed and delivered by the Borrower, will be the legal, valid, and binding obligations of the Borrower, enforceable against the Borrower in accordance with their respective terms. 4.4 Security Instruments. The provisions of each Security Instrument executed by the Borrower are effective to create in favor of the Agent, a legal, valid, and enforceable Lien in all right, title, and interest of the Borrower in the Collateral described therein, which Liens, assuming the accomplishment of recording and filing in accordance with applicable laws prior to the intervention of rights of other Persons, shall constitute fully perfected first-priority Liens on all right, title, and interest of the Borrower in the Collateral described therein. 4.5 Title to Assets. The Borrower has good and indefeasible title to all of its Properties, free and clear of all Liens except Permitted Liens. 4.6 Scope and Accuracy of Financial Statements. The Financial Statements of the Borrower as of September 30, 1994, present fairly the financial position and results of operations and cash flows of the Borrower in accordance with GAAP (except for the omission of footnotes and provision for income taxes) as at the relevant point in time or for the period indicated, as applicable, subject to normal year-end audit adjustments. No event or circumstance has occurred since September 30, 1994, which could reasonably be expected to have a Material Adverse Effect. 4.7 No Material Misstatements. No information, exhibit, statement, or report furnished to the Agent or any Lender by or at the direction of the Borrower in connection with this Agreement contains any material misstatement of fact or omits to state a material fact or any fact necessary to make the statements contained therein not misleading as of the date made or deemed made in light of the circumstances in which they were made. 4.8 Liabilities, Litigation, and Restrictions. Other than as disclosed in the Financial Statements provided to the Lenders on or before the Closing Date, the Borrower has no liabilities, direct, or contingent, which may materially and adversely affect its business or operations or its ownership of the Collateral. Except as disclosed in writing to the Lenders on the Closing Date, no litigation or other action of any nature affecting the Borrower in which the amount in controversy exceeds $100,000 is pending before any Governmental Authority or, to the best knowledge of the Borrower, threatened against or affecting the Borrower. No unusual or unduly burdensome restriction, restraint or hazard exists by contract, Requirement of Law, or otherwise relative to the business or operations of the Borrower or the ownership and operation of the Collateral other than such as relate generally to Persons engaged in business activities similar to those conducted by the Borrower, the effect of which could reasonably be expected to have a Material Adverse Effect. 4.9 Authorizations; Consents. Except as expressly contemplated by this Agreement, no authorization, consent, approval, exemption, franchise, permit, or license of, or filing with, any Governmental Authority or any other Person is required to authorize or is otherwise required in connection with the valid execution and delivery by the Borrower of the Loan Documents or any instrument contemplated hereby, the repayment by the Borrower of the Notes and interest and fees provided in the Notes and the other Loan Documents, or the performance by the Borrower of the Obligations. 4.10 Compliance with Laws. The Borrower and its Property are in compliance with all applicable Requirements of Law, including, without limitation, Environmental Laws, the Natural Gas Policy Act of 1978, as amended, and ERISA, except to the extent non-compliance with any such Requirements of Law could not reasonably be expected to have a Material Adverse Effect. 4.11 ERISA. No Reportable Event has occurred with respect to any Single Employer Plan, and each Single Employer Plan has complied with and been administered in all material respects in accordance with applicable provisions of ERISA and the Code. To the best knowledge of the Borrower, (a) no Reportable Event has occurred with respect to any Multiemployer Plan, and (b) each Multiemployer Plan has complied with and been administered in all material respects with applicable provisions of ERISA and the Code. The present value of all benefits vested under each Single Employer Plan maintained by the Borrower or any Commonly Controlled Entity (based on the assumptions used to fund such Plan) did not, as of the last annual valuation date applicable thereto, exceed the value of the assets of such Plan allocable to such vested benefits. Neither the Borrower nor any Commonly Controlled Entity has had a complete or partial withdrawal from any Multiemployer Plan for which there is any withdrawal liability. As of the most recent valuation date applicable to any Multiemployer Plan, neither the Borrower nor any Commonly Controlled Entity would become subject to any liability under ERISA if the Borrower or such Commonly Controlled Entity were to withdraw completely from such Multiemployer Plan. Neither the Borrower nor any Commonly Controlled Entity has received notice that any Multiemployer Plan is Insolvent or in Reorganization. To the best knowledge of the Borrower, no such Insolvency or Reorganization is reasonably likely to occur. The Borrower has no reason to believe that the annual cost during the term of this Agreement to the Borrower and all Commonly Controlled Entities for post-retirement benefits to be provided to the current and former employees of the Borrower and all Commonly Controlled Entities under Plans which are welfare benefit plans (as defined in Section 3(1) of ERISA) will, in the aggregate, have a Material Adverse Effect. 4.12 Environmental Laws. (a) No Property of the Borrower or either Pipeline Subsidiary is currently on or has ever been on, or, to the knowledge of the Borrower, is adjacent to any Property which is on or has ever been on, any federal or state list of Superfund Sites. (b) To the knowledge of the Borrower, no Hazardous Substances have been generated, transported, and/or disposed of by the Borrower or either Pipeline Subsidiary at a site which was, at the time of such generation, transportation, and/or disposal, or has since become, a Superfund Site. (c) No Release of Hazardous Substances by the Borrower or either Pipeline Subsidiary or from, affecting, or related to any Property of the Borrower or either Pipeline Subsidiary or, to the knowledge of the Borrower, adjacent to any Property of the Borrower or either Pipeline Subsidiary has occurred which could reasonably be expected to have a Material Adverse Effect. (d) No Environmental Complaint has been received by the Borrower or either Pipeline Subsidiary which has not been satisfactorily resolved. 4.13 Compliance with Federal Reserve Regulations. No transaction contemplated by the Loan Documents is in violation of any regulations promulgated by the Board of Governors of the Federal Reserve System, including, without limitation, Regulations G, T, U, or X. 4.14 Investment Company Act Compliance. The Borrower is not, nor is the Borrower directly or indirectly controlled by or acting on behalf of any Person which is, an "investment company" or an "affiliated person" of an "investment company" within the meaning of the Investment Company Act of 1940, as amended. 4.15 Public Utility Holding Company Act Compliance. The Borrower is not a "holding company," or an "affiliate" of a "holding company" or of a "subsidiary company" of a "holding company," within the meaning of the Public Utility Holding Company Act of 1935, as amended. 4.16 Proper Filing of Tax Returns; Payment of Taxes Due. All United States income tax returns and all other tax returns which are required to be filed on behalf of the Borrower have been filed, and all taxes owing by the Borrower and the Guarantors have been paid except such as are being contested in good faith and as to which adequate provisions and disclosures have been made in accordance with GAAP. The respective charges and reserves on the books of the Borrower and the Guarantors with respect to taxes and other governmental charges are adequate. 4.17 Intellectual Property. The Borrower owns or is licensed to use all Intellectual Property necessary to conduct all business material to its condition (financial or otherwise), business, or operations as such business is currently conducted. No claim has been asserted or is pending by any Person with the respect to the use of any such Intellectual Property or challenging or questioning the validity or effectiveness of any such Intellectual Property; and the Borrower knows of no valid basis for any such claim. The use of such Intellectual Property by the Borrower does not infringe on the rights of any Person, except for such claims and infringements as do not, in the aggregate, give rise to any material liability on the part of the Borrower. 4.18 Casualties or Taking of Property. Since September 30, 1994, neither the business nor any Property of the Borrower has been materially adversely affected as a result of any fire, explosion, earthquake, flood, drought, windstorm, accident, strike or other labor disturbance, embargo, requisition or taking of Property, or cancellation of contracts, permits, or concessions by any Governmental Authority, riot, activities of armed forces, or acts of God. 4.19 Locations of Borrower. The principal place of business and chief executive office of the Borrower is located at the address of the Borrower set forth on the signature pages hereof or at such other location as the Borrower may have, by proper written notice hereunder, advised the Agent and the Lenders, provided that such other location is within a state in which appropriate financing statements from the Borrower in favor of the Agent have been filed. 4.20 Subsidiaries. The Borrower has no Subsidiaries except for the Pipeline Subsidiaries, the Pipeline Subsidiaries have no Subsidiaries, and Howell Corporation has no Subsidiaries except those described on Exhibit XI under the heading "Subsidiaries of Howell Corporation." ARTICLE V AFFIRMATIVE COVENANTS So long as any Obligation remains outstanding or unpaid or any Commitment exists, the Borrower shall: 5.1 Maintenance and Access to Records.

Each Lender authorizes the Agent, as the agent for such Lender, to take such action on behalf of such Lender under the provisions of this Agreement and the other Loan Documents and to exercise such powers and perform such duties as are expressly delegated to the Agent by the terms of this Agreement and the other Loan Documents, together with such other powers as are reasonably incidental thereto. Notwithstanding any provision to the contrary elsewhere in this Agreement or in any other Loan Document, the Agent shall not have any duties or responsibilities except those expressly set forth herein or in any other Loan Document or any fiduciary relationship with any Lender; and no implied covenants, functions, responsibilities, duties, obligations, or liabilities on the part of the Agent shall be read into this Agreement or any other Loan Document or otherwise exist against the Agent. 8.2 Delegation of Duties. The Agent may execute any of its duties under this Agreement and the other Loan Documents by or through agents or attorneys-in-fact and shall be entitled to advice of counsel concerning all matters pertaining to such duties. The Agent shall not be responsible for the negligence or misconduct of any agents or attorneys-in-fact selected by it with reasonable care. 8.3 Exculpatory Provisions. Neither the Agent nor any of its officers, directors, employees, agents, attorneys-in-fact or affiliates shall be (a) required to initiate or conduct any litigation or collection proceedings hereunder, except with the concurrence of the Required Lenders and contribution by each Lender of its Term Loan Percentage Share of costs reasonably expected by the Agent to be incurred in connection therewith, (b) liable for any action lawfully taken or omitted to be taken by it or such Person under or in connection with this Agreement or any other Loan Document (except for gross negligence or willful misconduct of the Agent or such Person), or (c) responsible in any manner to any Lender for any recitals, statements, representations or warranties made by the Borrower or any officer thereof contained in this Agreement or any other Loan Document or in any certificate, report, statement or other document referred to or provided for in, or received by the Agent under or in connection with, this Agreement or any other Loan Document, or for the sufficiency, accuracy, or completeness of any materials provided by the Agent, or the failure of the Agent to provide any materials or disclose any matter to any Lender except as may be expressly required herein, or for the value, validity, effectiveness, genuineness, enforceability or sufficiency of this Agreement or any other Loan Document or for any failure of the Borrower to perform its obligations hereunder or thereunder. The Agent shall not be under any obligation to any Lender to ascertain or to inquire as to the observance or performance of any of the agreements contained in, or conditions of, this Agreement or any other Loan Document, or to inspect the properties, books or records of the Borrower. 8.4 Reliance by Agent. The Agent shall be entitled to rely, and shall be fully protected in relying, upon any Note, writing, resolution, notice, consent, certificate, affidavit, letter, cablegram, telegram, telecopy, telex or teletype message, statement, order or other document or conversation believed by it to be genuine and correct and to have been signed, sent or made by the proper Person or Persons and upon advice and statements of legal counsel (including, without limitation, counsel to the Borrower), independent accountants and other experts selected by the Agent. The Agent may deem and treat the payee of any Note as the owner thereof for all purposes unless and until a written notice of assignment, negotiation, or transfer thereof shall have been received by the Agent. The Agent shall be fully justified in failing or refusing to take any action under this Agreement or any other Loan Document unless it shall first receive such advice or concurrence of the Required Lenders as it deems appropriate and contribution by each Lender of its Term Loan Percentage Share of costs reasonably expected by the Agent to be incurred in connection therewith. The Agent shall in all cases be fully protected in acting, or in refraining from acting, under this Agreement and the other Loan Documents in accordance with a request of the Required Lenders.

The Agent shall not be deemed to have knowledge or notice of the occurrence of any Default or Event of Default unless the Agent has received notice from a Lender or the Borrower 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 Agent receives such a notice, the Agent shall promptly give notice thereof to the Lenders. The Agent shall take such action with respect to such Default or Event of Default as shall be reasonably directed by the Required Lenders; provided that unless and until the Agent shall have received such directions, subject to the provisions of Section 7.2, the Agent may (but shall not be obligated to) take such action, or refrain from taking such action, with respect to such Default or Event of Default as it shall deem advisable in the best interests of the Lenders. In the event that the officer of the Agent primarily responsible for the lending relationship with the Borrower or the officer of any Lender primarily responsible for the lending relationship with the Borrower becomes aware that a Default or Event of Default has occurred and is continuing, the Agent or such Lender, as the case may be, shall use its good faith efforts to inform the other Lenders and/or the Agent, as the case may be, promptly of such occurrence. Notwithstanding the preceding sentence, failure to comply with the preceding sentence shall not result in any liability to the Agent or any Lender. 8.6 Non-Reliance on Agent and Other Lenders. Each Lender expressly acknowledges that neither the Agent nor any other Lender nor any of their respective officers, directors, employees, agents, attorneys-in-fact or affiliates has made any representation or warranty to such Lender and that no act by the Agent or any other Lender hereafter taken, including any review of the affairs of the Borrower, shall be deemed to constitute any representation or warranty by the Agent or any Lender to any other Lender. Each Lender represents to the Agent that it has, independently and without reliance upon the Agent or any other Lender, and based on such documents and information as it has deemed appropriate, made its own appraisal of and investigation into the business, operations, property, condition (financial and otherwise) and creditworthiness of the Borrower and the value of the Collateral and other Properties of the Borrower and has made its own decision to enter into this Agreement. Each Lender also represents that it will, independently and without reliance upon the Agent or any other Lender and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit analysis, appraisals and decisions in taking or not taking action under this Agreement and the other Loan Documents, and to make such investigation as it deems necessary to inform itself as to the business, operations, property, condition (financial and otherwise) and creditworthiness of the Borrower and the value of the Collateral and other Properties of the Borrower. Except for notices, reports and other documents expressly required to be furnished to the Lenders by the Agent hereunder, the Agent shall not have any duty or responsibility to provide any Lender with any credit or other information concerning the business, operations, property, condition (financial and otherwise), or creditworthiness of the Borrower or the value of the Collateral or other Properties of the Borrower which may come into the possession of the Agent or any of its officers, directors, employees, agents, attorneys-in-fact or affiliates. 8.7 Indemnification. EACH LENDER AGREES TO INDEMNIFY THE AGENT AND ITS OFFICERS, DIRECTORS, EMPLOYEES, AGENTS, ATTORNEYS-IN-FACT AND AFFILIATES (TO THE EXTENT NOT REIMBURSED BY THE BORROWER AND WITHOUT LIMITING THE OBLIGATION OF THE BORROWER TO DO SO), RATABLY ACCORDING TO THE TERM LOAN PERCENTAGE SHARE OF SUCH LENDER, FROM AND AGAINST ANY AND ALL LIABILITIES, CLAIMS, OBLIGATIONS, LOSSES, DAMAGES, PENALTIES, ACTIONS, JUDGMENTS, SUITS, COSTS, EXPENSES AND DISBURSEMENTS OF ANY KIND WHATSOEVER WHICH MAY AT ANY TIME (INCLUDING, WITHOUT LIMITATION, ANY TIME FOLLOWING THE PAYMENT AND PERFORMANCE OF ALL OBLIGATIONS AND THE TERMINATION OF THIS AGREEMENT) BE IMPOSED ON, INCURRED BY OR ASSERTED AGAINST THE AGENT OR ANY OF ITS OFFICERS, DIRECTORS, EMPLOYEES, AGENTS, ATTORNEYS-IN-FACT OR AFFILIATES IN ANY WAY RELATING TO OR ARISING OUT OF THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT, OR ANY OTHER DOCUMENT CONTEMPLATED OR REFERRED TO HEREIN OR THE TRANSACTIONS CONTEMPLATED HEREBY OR ANY ACTION TAKEN OR OMITTED BY THE AGENT OR ANY OF ITS OFFICERS, DIRECTORS, EMPLOYEES, AGENTS, ATTORNEYS-IN-FACT OR AFFILIATES UNDER OR IN CONNECTION WITH ANY OF THE FOREGOING, INCLUDING, WITHOUT LIMITATION, ANY LIABILITIES, CLAIMS, OBLIGATIONS, LOSSES, DAMAGES, PENALTIES, ACTIONS, JUDGMENTS, SUITS, COSTS, EXPENSES AND DISBURSEMENTS IMPOSED, INCURRED OR ASSERTED AS A RESULT OF THE NEGLIGENCE, WHETHER SOLE OR CONCURRENT, OF THE AGENT OR ANY OF ITS OFFICERS, DIRECTORS, EMPLOYEES, AGENTS, ATTORNEYS-IN-FACT OR AFFILIATES; PROVIDED THAT NO LENDER SHALL BE LIABLE FOR THE PAYMENT OF ANY PORTION OF SUCH LIABILITIES, OBLIGATIONS, LOSSES, DAMAGES, PENALTIES, ACTIONS, JUDGMENTS, SUITS, COSTS, EXPENSES OR DISBURSEMENTS RESULTING SOLELY FROM THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF THE AGENT OR ANY OF ITS OFFICERS, DIRECTORS, EMPLOYEES, AGENTS, ATTORNEYS-IN- FACT OR AFFILIATES. THE AGREEMENTS IN THIS SECTION SHALL SURVIVE THE PAYMENT AND PERFORMANCE OF ALL OBLIGATIONS AND THE TERMINATION OF THIS AGREEMENT. 8.8 Restitution. Should the right of the Agent or any Lender to realize funds with respect to the Obligations be challenged and any application of such funds to the Obligations be reversed, whether by Governmental Authority or otherwise, or should the Borrower otherwise be entitled to a refund or return of funds distributed to the Lenders in connection with the Obligations, the Agent or such Lender, as the case may be, shall promptly notify the Lenders of such fact. Not later than Noon, Central Standard or Daylight Savings Time, as the case may be, of the Business Day following such notice, each Lender shall pay to the Agent an amount equal to the ratable share of such Lender of the funds required to be returned to the Borrower. The ratable share of each Lender shall be determined on the basis of the percentage of the payment all or a portion of which is required to be refunded originally distributed to such Lender, if such percentage can be determined, or, if such percentage cannot be determined, on the basis of the Term Loan Percentage Share of such Lender. The Agent shall forward such funds to the Borrower or to the Lender required to return such funds. If any such amount due to the Agent is made available by any Lender after Noon, Central Standard or Daylight Savings Time, as the case may be, of the Business Day following such notice, such Lender shall pay to the Agent (or the Lender required to return funds to the Borrower, as the case may be) for its own account interest on such amount at a rate equal to the Federal Funds Rate for the period from and including the date on which restitution to the Borrower is made by the Agent (or the Lender required to return funds to the Borrower, as the case may be) to but not including the date on which such Lender failing to timely forward its share of funds required to be returned to the Borrower shall have made its ratable share of such funds available. 8.9 Agent in Its Individual Capacity. The Agent and its affiliates may make loans to, accept deposits from and generally engage in any kind of business with the Borrower as though the Agent were not the agent hereunder. With respect to any Note issued to the Lender serving as the Agent, the Agent shall have the same rights and powers under this Agreement as a Lender and may exercise such rights and powers as though it were not the Agent. The terms "Lender" and "Lenders" shall include the Agent in its individual capacity. 8.10 Successor Agent. The Agent may resign as Agent upon ten days' notice to the Lenders and the Borrower. If the Agent shall resign as Agent under this Agreement and the other Loan Documents, Lenders for which the Term Loan Percentage Shares aggregate at least 60% shall appoint from among the Lenders a successor agent for the Lenders, whereupon such successor agent shall succeed to the rights, powers and duties of the Agent. The term "Agent" shall mean such successor agent effective upon its appointment. The rights, powers, and duties of the former Agent as Agent shall be terminated, without any other or further act or deed on the part of such former Agent or any of the parties to this Agreement or any holders of the Notes. After the removal or resignation of any Agent hereunder as Agent, the provisions of this Article VIII and Sections 2.2(d), 5.12, and 5.17 shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Agent under this Agreement and the other Loan Documents. 8.11 Applicable Parties. The provisions of this Article are solely for the benefit of the Agent and the Lenders, and the Borrower shall not have any rights as a third party beneficiary or otherwise under any of the provisions of this Article. In performing functions and duties hereunder and under the other Loan Documents, the Agent shall act solely as the agent of the Lenders and does not assume, nor shall it be deemed to have assumed, any obligation or relationship of trust or agency with or for the Borrower or any legal representative, successor, and assign of the Borrower.

Any such assignment of rights and obligations of a Lender hereunder shall become effective upon the execution and delivery to the Agent of the Assignment Agreement and the consent of the Agent. Promptly following receipt of an executed Assignment Agreement, the Agent shall send to the Borrower a copy of such executed Assignment Agreement. Promptly following receipt of such executed Assignment Agreement, the Borrower shall execute and deliver, at its own expense, new Notes to the assignee and, if applicable, the assignor, in accordance with their respective interests, whereupon the prior Notes of the assignor and, if applicable, the assignee, shall be cancelled and returned to the Borrower. Upon the effectiveness of any assignment pursuant to this Section 9.1(b), the assignee will become a "Lender," if not already a "Lender," for all purposes of the Loan Documents, and the assignor shall be relieved of its obligations hereunder to the extent of such assignment. If the assignor no longer holds any rights or obligations under this Agreement, such assignor shall cease to be a "Lender" hereunder, except that its rights under Sections 2.21 and 5.17 shall not be affected. On the last Business Day of each month during which an assignment has become effective pursuant to this Section 9.1(b), the Agent shall prepare a new Exhibit IV giving effect to all such assignments effected during such month and will promptly provide a copy thereof to the Borrower and each Lender. (c) Each Lender may transfer, grant, or assign participations in all or any portion of its interests hereunder to its affiliates only pursuant to this Section 9.1(c), provided that such Lender shall remain a "Lender" for all purposes of this Agreement and the transferee of such participation shall not constitute a "Lender" hereunder. In the case of any such participation, the participant shall not have any rights under any Loan Document, the rights of the participant in respect of such participation to be against the granting Lender as set forth in the agreement with such Lender creating such participation, and all amounts payable by the Borrower hereunder shall be determined as if such Lender had not sold such participation. (d) The Lenders may furnish any information concerning the Borrower in the possession of the Lenders from time to time to permitted assignees and participants and, with the consent of the Borrower, to prospective assignees and participants. (e) Notwithstanding anything in this Section to the contrary, any Lender may assign and pledge all or any of its Notes or any interest therein to any Federal Reserve Bank or the United States Treasury as collateral security pursuant to Regulation A of the Board of Governors of the Federal Reserve System and any operating circular issued by such Federal Reserve System and/or such Federal Reserve Bank. No such assignment or pledge shall release the assigning or pledging Lender from its obligations hereunder. (f) Notwithstanding any other provisions of this Section, no transfer or assignment of the interests or obligations of any Lender or grant of participations therein shall be permitted if such transfer, assignment, or grant would require the Borrower to file a registration statement with the Securities and Exchange Commission or any successor Governmental Authority or qualify the Loans under the "Blue Sky" laws of any state. 9.2 Survival of Representations, Warranties, and Covenants. All representations and warranties of the Borrower and all covenants and agreements herein made shall survive the execution and delivery of the Notes and the Security Instruments and shall remain in force and effect so long as any Obligation is outstanding or any Commitment exists. 9.3 Notices. Except as to oral notices expressly authorized herein, which oral notices shall be confirmed in writing, all notices, requests, and communications hereunder shall be in writing (including by telecopy). Unless otherwise expressly provided herein, any such notice, request, demand, or other communication shall be deemed to have been duly given or made when delivered by hand, or, in the case of delivery by mail, two Business Days after deposited in the mail, certified mail, return receipt requested, postage prepaid, or, in the case of telecopy notice, when receipt thereof is acknowledged orally or by written confirmation report, addressed to each party at the "Address for Notices" specified below its name on the signature pages hereof or at such other address as shall be designated by such party in a properly given notice. 9.4 Parties in Interest. Subject to the restrictions on changes in corporate structure set forth in Section 6.8 and other applicable restrictions contained herein, all covenants and agreements herein contained by or on behalf of the Borrower, the Agent, or the Lenders shall be binding upon and inure to the benefit of the Borrower, the Agent, or the Lenders, as the case may be, and their respective legal representatives, successors, and permitted assigns. 9.5 Rights of Third Parties. All provisions herein are imposed solely and exclusively for the benefit of the Agent, the Lenders and the Borrower and their successors and permitted assigns. No other Person shall have any right, benefit, priority, or interest hereunder or as a result hereof or have standing to require satisfaction of provisions hereof in accordance with their terms. 9.6 No Waiver; Rights Cumulative. No course of dealing on the part of the Agent or the Lenders or their officers or employees, nor any failure or delay by the Agent or the Lenders with respect to exercising any of their rights under any Loan Document shall operate as a waiver thereof. The rights of the Agent and the Lenders under the Loan Documents shall be cumulative and the exercise or partial exercise of any such right shall not preclude the exercise of any other right. Neither the making of the Loan nor the issuance of a Letter of Credit shall constitute a waiver of any of the covenants, warranties, or conditions of the Borrower contained herein. In the event the Borrower is unable to satisfy any such covenant, warranty, or condition, neither the making of the Loan nor the issuance of a Letter of Credit shall have the effect of precluding the Agent or the Lenders from thereafter declaring such inability to be an Event of Default as hereinabove provided. 9.7 Survival Upon Unenforceability. In the event any one or more of the provisions contained in any of the Loan Documents or in any other instrument referred to herein or executed in connection with the Obligations shall, for any reason, be held to be invalid, illegal, or unenforceable in any respect, such invalidity, illegality, or unenforceability shall not affect any other provision of any Loan Document or of any other instrument referred to herein or executed in connection with such Obligations. 9.8 Amendments; Waivers. Neither this Agreement nor any of the other Loan Documents nor any terms hereof or thereof may be amended, supplemented, modified, or waived except in writing and in accordance with the provisions of this Section. The Agent and the Borrower may, from time to time with the written consent of the Required Lenders, enter into written amendments, supplements, or modifications to the Loan Documents for the purpose of adding any provisions to this Agreement or the other Loan Documents or changing in any manner the rights of the Lenders or the Borrower hereunder or thereunder or waiving, on such terms and conditions as the Agent may specify in such instrument, any of the requirements of this Agreement or the other Loan Documents or any Default or Event of Default and its consequences; provided, however, that no such amendment, supplement, modification, or waiver shall (a) extend the time of payment of any Obligation, change the rate of interest thereon, extend the Commitment Termination Date or Final Maturity, reduce any fee payable for the account of the Lenders hereunder, release any Collateral, reduce the amount of any Obligation, increase the Maximum L/C Commitment Amount or the Maximum Term Loan Commitment Amount, change the Borrowing Base or any provision applicable to the determination of the Borrowing Base, amend, modify, or waive any provision of this Section or Sections 3.2, 5.12, 5.17, or 8.10, change the percentage specified in the definition of Required Lenders, or consent to the assignment or transfer by the Borrower of any of its rights or obligations under this Agreement or the other Loan Documents, in any such case without the written consent of all Lenders, or (b) amend, modify, or waive any provision of Article VIII or the rights or obligations of the Agent (including its rights and obligations as issuer of the Letters of Credit) without the written consent of the Agent. Any such amendment, supplement, modification, or waiver shall apply equally to each of the Lenders and shall be binding upon the Borrower, the Lenders, and the Agent and all future holders of the Notes. Notwithstanding the foregoing, the Agent may, provided that no Default or Event of Default exists, release Collateral the value of which, as reasonably determined by the Agent, in any fiscal year of the Borrower does not exceed $1,000,000. In the event of any waiver, the Borrower, the Lenders, and the Agent shall be restored to their respective former positions and rights hereunder and under the other Loan Documents, and any Default or Event of Default waived shall be deemed to be cured and not continuing; but no such waiver shall extend to any subsequent or other Default or Event of Default or impair any right with respect thereto. 9.9 Controlling Agreement. In the event of a conflict between the provisions of this Agreement and those of any other Loan Document, the provisions of this Agreement shall control. 9.10 GOVERNING LAW. THIS AGREEMENT, THE NOTES, AND THE GUARANTIES SHALL BE DEEMED TO BE CONTRACTS MADE UNDER AND SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY THE LAWS OF THE STATE OF TEXAS WITHOUT GIVING EFFECT TO PRINCIPLES THEREOF RELATING TO CONFLICTS OF LAW; PROVIDED, HOWEVER, THAT VERNON'S TEXAS CIVIL STATUTES, ARTICLE 5069, CHAPTER 15 (WHICH REGULATES CERTAIN REVOLVING CREDIT LOAN ACCOUNTS AND REVOLVING TRIPARTY ACCOUNTS) SHALL NOT APPLY. 9.11 JURISDICTION AND VENUE. ALL ACTIONS OR PROCEEDINGS WITH RESPECT TO, ARISING DIRECTLY OR INDIRECTLY IN CONNECTION WITH, OUT OF, RELATED TO, OR FROM THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT MAY BE LITIGATED, AT THE SOLE DISCRETION AND ELECTION OF THE AGENT, IN COURTS HAVING SITUS IN HOUSTON, HARRIS COUNTY, TEXAS. THE BORROWER HEREBY SUBMITS TO THE JURISDICTION OF ANY LOCAL, STATE, OR FEDERAL COURT LOCATED IN HOUSTON, HARRIS COUNTY, TEXAS, AND HEREBY WAIVES ANY RIGHTS IT MAY HAVE TO TRANSFER OR CHANGE THE JURISDICTION OR VENUE OF ANY LITIGATION BROUGHT AGAINST IT BY THE AGENT OR ANY LENDER IN ACCORDANCE WITH THIS SECTION. 9.12 WAIVER OF RIGHTS TO JURY TRIAL. THE BORROWER, THE AGENT, AND EACH LENDER HEREBY KNOWINGLY, VOLUNTARILY, INTENTIONALLY, IRREVOCABLY, AND UNCONDITIONALLY WAIVE ALL RIGHTS TO TRIAL BY JURY IN ANY ACTION, SUIT, PROCEEDING, COUNTERCLAIM, OR OTHER LITIGATION THAT RELATES TO OR ARISES OUT OF ANY OF THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT OR THE ACTS OR OMISSIONS OF THE AGENT OR ANY LENDER IN THE ENFORCEMENT OF ANY OF THE TERMS OR PROVISIONS OF THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT OR OTHERWISE WITH RESPECT THERETO. THE PROVISIONS OF THIS SECTION ARE A MATERIAL INDUCEMENT FOR THE AGENT AND THE LENDERS ENTERING INTO THIS AGREEMENT. 9.13 ENTIRE AGREEMENT. THIS AGREEMENT AMENDS, RESTATES AND REPLACES THE EXISTING CREDIT AGREEMENT AND CONSTITUTES THE ENTIRE AGREEMENT AMONG THE PARTIES HERETO WITH RESPECT TO THE SUBJECT HEREOF AND SHALL SUPERSEDE ANY PRIOR AGREEMENT BETWEEN OR AMONG THE PARTIES HERETO, WHETHER WRITTEN OR ORAL, RELATING TO THE SUBJECT HEREOF, INCLUDING, WITHOUT LIMITATION, THE EXISTING CREDIT AGREEMENT AND THE CORRESPONDENCE DATED FEBRUARY 9, 1995, FROM BANK ONE TO THE GUARANTOR AND THE TERM SHEET ENCLOSED THEREWITH. FURTHERMORE, IN THIS REGARD, THIS AGREEMENT AND THE OTHER WRITTEN LOAN DOCUMENTS REPRESENT, COLLECTIVELY, THE FINAL AGREEMENT AMONG THE PARTIES THERETO AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL AGREEMENTS OF SUCH PARTIES. THERE ARE NO UNWRITTEN ORAL AGREEMENTS AMONG SUCH PARTIES. 9.14 Counterparts. For the convenience of the parties, this Agreement may be executed in multiple counterparts and by different parties hereto in separate counterparts, each of which when so executed shall be deemed to be an original, and all of which shall together constitute but one and the same agreement. IN WITNESS WHEREOF, this Agreement is executed as of the date first above written. BORROWER: HOWELL CRUDE OIL COMPANY By: /s/ Mark J. Gorman ------------------ Mark J.
