Notice of Borrowings. The Borrower shall give the Administrative Agent notice (a "Notice of Borrowing") substantially in the form of Exhibit 2.02 hereto not later than 10:00 A.M. (Houston time) on (i) the date of each Base Rate Borrowing or each Euro-Dollar Borrowing with an Interest Period of seven days or less (ii) the second Domestic Business Day before each CD Borrowing and (iii) the third Euro-Dollar Business Day before each Euro- Dollar Borrowing with an Interest Period greater than seven days, specifying: (a) the date of such Borrowing, which shall be a Domestic Business Day in the case of a Domestic Borrowing or a Euro-Dollar Business Day in the case of a Euro-Dollar Borrowing; (b) the aggregate amount of such Borrowing; (c) whether the Loans comprising such Borrowing are to be CD Loans, Base Rate Loans or Euro-Dollar Loans or a combination thereof; (d) in the case of a Fixed Rate Borrowing, the duration of the Interest Period applicable thereto, subject to the provisions of the definition of Interest Period; and (e) the aggregate outstanding principal amount of Debt of the Borrower and its Subsidiaries incurred after the Effective Date and, if required, a calculation as of the date of such Notice of Borrowing pursuant to Section 5.08(a). SECTION 2.03. Letters of Credit. (a) Subject to and upon the terms and conditions hereof and the execution and delivery of a letter of credit application ("Letter of Credit Application"), and a letter of credit request ("Letter of Credit Request") substantially in the form of Exhibit 2.03(b) hereto, the Issuing Bank agrees that it will, at any time and from time to time on or after the Effective Date and prior to the Letter of Credit Termination Date, renew, extend and issue for the account of the Borrower (in support of its obligations and the obligations of its Consolidated Subsidiaries) one or more irrevocable standby letters of credit (all such letters of credit collectively, the "Letters of Credit"); provided, 15 however, that the Issuing Bank shall not extend, renew or issue any Letter of Credit if at the time of such issuance, extension or renewal: (i) the Stated Amount of such Letter of Credit shall be greater than an amount which when added to the Letter of Credit Outstandings at such time and the aggregate principal amount of all Loans then outstanding or requested would exceed the aggregate amount of the Banks' Commitments; or (ii) the Stated Amount of such Letter of Credit shall be greater than an amount which when added to the Letter of Credit Outstandings at such time, would exceed the Letter of Credit Limit; or (iii) the expiry date or, in the case of any Letter of Credit containing an expiry date that is extendible at the option of the Issuing Bank, the initial expiry date of such Letter of Credit, is a date that is later than the Letter of Credit Termination Date; or (iv) such issuance, renewal or extension shall be prohibited by applicable law. (b) The Issuing Bank shall neither renew nor permit the renewal of any Letter of Credit if any of the conditions precedent to such renewal set forth in Section 3.02 are not satisfied or, after giving effect to such renewal, the expiry date of such Letter of Credit would be a date that is later than the Letter of Credit Termination Date. (c) Whenever the Borrower requests that a Letter of Credit be issued or renewed for its account or an existing expiry date be extended, it shall forward an executed Letter of Credit Request and Letter of Credit Application to the Issuing Bank (with copies to be sent to the Administrative Agent (if different from the Issuing Bank)) (i) in the case of a Letter of Credit to be issued or renewed at least four Domestic Business Days' prior to the proposed date of issuance or renewal and (ii) in the case of the extension of the existing expiry date of any Letter of Credit, at least five Domestic Business Days prior to the date on which the Issuing Bank must notify the beneficiary thereof that the Issuing Bank does not intend to extend such existing expiry date. Each Letter of Credit shall be denominated in U.S. dollars, shall expire no later than the date specified in paragraph (a) above, shall not be in an amount greater than is permitted under this Section 2.03 and shall be in such form as may be approved from time to time by the Issuing Bank and the Borrower. At the time of issuance, the Issuing Bank shall designate the Letter of Credit as either a Financial Letter of Credit or a Performance Letter of Credit, which designation shall be final. (d) The making of each Letter of Credit Request shall be deemed to be a representation and warranty by the Borrower that such Letter of Credit may be 16 renewed, extended or issued in accordance with, and will not violate the requirements of this Agreement. Unless the Issuing Bank has received notice from the Administrative Agent (if different from the Issuing Bank) before it issues or renews the respective Letter of Credit or extends the existing expiry date of a Letter of Credit that one or more of the conditions specified in Article III are not then satisfied, or that the renewal, extension or issuance of such Letter of Credit would violate any of the terms of this Agreement, then the Issuing Bank may renew, extend or issue the requested Letter of Credit for the account of the Borrower (in support of its obligations and the obligations of its Consolidated Subsidiaries) in accordance with the Issuing Bank's usual and customary practices. Upon its issuance or renewal of any Letter of Credit or the extension of the existing expiry date of any Letter of Credit, as the case may be, the Issuing Bank shall promptly notify the Borrower, the Administrative Agent and each Bank of such issuance, renewal or extension, which notice shall be accompanied by a copy of the Letter of Credit actually issued or renewed or a copy of any amendment extending the existing expiry date of any Letter of Credit, as the case may be. (e) Upon the renewal, extension or issuance by the Issuing Bank of each Letter of Credit, the Issuing Bank shall be deemed to have sold and transferred to each Bank, and each Bank shall be deemed irrevocably and unconditionally to have purchased and received from the Issuing Bank, without recourse or warranty, an undivided interest and participation, to the extent of such Bank's Commitment Percentage in each such Letter of Credit (including extensions of the expiry date thereof), each substitute letter of credit, each drawing made thereunder and the Obligations of the Borrower under this Agreement and the other Loan Documents with respect thereto and any security, if any, therefor. (f) In determining whether to pay under any Letter of Credit, the Issuing Bank shall have no obligation relative to the Banks other than to confirm that any documents required to be delivered under such Letter of Credit appear to have been delivered and that they appear to comply on their face with the requirements of such Letter of Credit. (g) Upon the receipt by the Issuing Bank of any documentation presented for a drawing from a beneficiary under a Letter of Credit, the Issuing Bank promptly will provide the Administrative Agent (if different from the Issuing Bank), the Banks and the Borrower with telecopy notice thereof and the Issuing Bank will promptly examine the documentation presented for such drawing in accordance with its customary procedures for conformity to the requirements of such Letter of Credit. The Borrower hereby agrees to reimburse the Issuing Bank by making payment to the Administrative Agent in immediately available funds (which payment may be made by application of the proceeds of Loans made to the Borrower in accordance with this Agreement) for any payment so made by the Issuing Bank under any Letter of Credit issued by it 17 (each such amount so paid until reimbursed by the Borrower, including by application of the proceeds of Loans to the Borrower in accordance with this Agreement, an "Unpaid Drawing") upon demand on or after the date of such payment, with interest on the amount so paid by the Issuing Bank, to the extent not reimbursed prior to 2:00 p.m. (Houston time) on the date of such payment, from and including the date paid to but excluding the date reimbursement is made as provided above, at a rate per annum equal to the lesser of (i) the sum of 2 percent plus the Base Rate or (ii) the Highest Lawful Rate. (h) In the event that the Issuing Bank makes any payment under any Letter of Credit and the Borrower shall not have reimbursed such amount in full to the Issuing Bank (including by any application of the proceeds of Loans) pursuant to paragraph (g) above, the Issuing Bank shall promptly notify the Administrative Agent (if different from the Issuing Bank) and the Administrative Agent, shall promptly notify each Bank of such failure, and each Bank shall promptly and unconditionally pay the Administrative Agent for the account of the Issuing Bank the amount of such Bank's Commitment Percentage of such unreimbursed payment in dollars and in funds immediately available in Houston. If the Administrative Agent so notifies, prior to 11:00 a.m. (Houston time) on any Domestic Business Day, any Bank required to fund a payment under a Letter of Credit, such Bank shall make available to the Administrative Agent for the account of the Issuing Bank such Bank's Commitment Percentage of the amount of such payment on such Domestic Business Day in funds immediately available in Houston. If and to the extent such Bank shall not have so made its Commitment Percentage of the amount of such payment available to the Administrative Agent for the account of the Issuing Bank, such Bank agrees to pay to the Administrative Agent for the account of the Issuing Bank, forthwith on demand such amount, together with the interest thereon, for each day from such date until the date such amount is paid to the Administrative Agent for the account of the Issuing Bank at the Federal Funds Rate. The failure of any Bank to make available to the Administrative Agent for the account of the Issuing Bank, its Commitment Percentage of any payment under any Letter of Credit shall not relieve any other Bank of its obligation hereunder to make available to the Administrative Agent for the account of the Issuing Bank its Commitment Percentage of any payment under any Letter of Credit on the date required, as specified above, but no Bank shall be responsible for the failure of any other Bank to make available to the Administrative Agent for the account of the Issuing Bank such other Bank's Commitment Percentage of any such payment. (i) Whenever the Issuing Bank receives a payment of a reimbursement obligation as to which the Administrative Agent has received for the account of the Issuing Bank any payments from a Bank pursuant to paragraph (h) above, the Issuing Bank shall pay to the Administrative Agent (if different from the Issuing Bank) and the Administrative Agent shall promptly pay to each Bank which has paid its 18 Commitment Percentage thereof, in dollars and in same day funds, an amount equal to such Bank's Commitment Percentage thereof together with any interest on such reimbursement obligation allocable to such Bank's Commitment Percentage paid by the Borrower to the Issuing Bank and received by the Administrative Agent pursuant to paragraph (g) above. (j) The obligations of the Banks to make payments to the Administrative Agent for the account of the Issuing Bank with respect to Letters of Credit shall be irrevocable and not subject to any qualification or exception whatsoever (except for the gross negligence or willful misconduct of the Issuing Bank) and shall be made in accordance with the terms and conditions of this Agreement under all circumstances, including any of the following circumstances: (1) any lack of validity or enforceability of this Agreement or any of the other Loan Documents; (2) the existence of any claim, setoff, defense or other right which the Borrower may have at any time against a beneficiary named in a Letter of Credit, any transferee of Letter of Credit, any Agent, the Issuing Bank, any other Bank, or any other Person, whether in connection with this Agreement, any Letter of Credit, the transactions contemplated herein or any unrelated transactions; (3) any draft, certificate or any other document presented under the Letter of Credit proving to be forged, fraudulent, invalid or insufficient in any respect or any statement therein being untrue or inaccurate in any respect; (4) the surrender or impairment of any security for the performance or observance of any of the terms of any of the Loan Documents; or (5) the occurrence of any Default or Event of Default. (k) The Borrower also agrees with the Issuing Bank and the Banks that the Issuing Bank shall not be responsible for, and the Borrower's reimbursement obligations under paragraph (g) above are absolute and unconditional and shall not be affected by any of the following (absent any gross negligence, willful misconduct or violation of law on the part of any of the Issuing Bank, the Agents and the other Banks): the validity or genuineness of documents or any endorsements thereon, even though such documents shall in fact prove to be invalid, fraudulent or forged, or any dispute between or among the Borrower and the beneficiary of any letter of Credit or any other party to which such Letter of Credit may be transferred or any claims whatsoever of the Borrower against any beneficiary of such Letter of Credit or any 19 such transferee or any other matter or event similar to any of the foregoing or any setoff, counterclaim or defense to payment which the Borrower may have. (l) The Issuing Bank, its officers, directors, agents and employees, shall not be liable for any error, omission, interruption or delay in transmission, dispatch or delivery of any message or advice, however transmitted, in connection with any Letter of Credit, except for errors, omissions, interruptions or delays caused by the Issuing Bank's gross negligence or willful misconduct or violation of law. IT IS THE EXPRESS INTENTION OF THE PARTIES HERETO THAT THE ISSUING BANK SHALL BE INDEMNIFIED AND HELD HARMLESS AGAINST ANY AND ALL LOSSES, LIABILITIES, CLAIMS, DEFICIENCIES, JUDGMENTS OR REASONABLE EXPENSES ARISING OUT OF OR RESULTING FROM THE ORDINARY NEGLIGENCE (WHETHER SOLE OR CONTRIBUTORY) OF THE ISSUING BANK IN CONNECTION WITH ANY SUCH ERROR, OMISSION, INTERRUPTION OR DELAY AS AFORESAID. The Borrower agrees that any action taken or omitted by the Issuing Bank under or in connection with any Letter of Credit or the related drafts or documents if done in accordance with the standards of care specified in the Uniform Customs and Practice for Documentary Credits (1983 Revision), International Chamber of Commerce, Publication No. 400 (and any subsequent revisions thereof approved by a Congress of the International Chamber of Commerce and adhered to by the Issuing Bank) and, to the extent not inconsistent therewith, the Uniform Commercial Code of the State of Texas, shall not result in any liability of the Issuing Bank to the Borrower. (m) To the extent that any provision of any Letter of Credit Application related to any Letter of Credit is inconsistent with the provisions of this Agreement, the provisions of this Agreement shall control and no Letter of Credit Application or any other document relating to any Letter of Credit shall give the Agents or the Banks any additional rights than they would otherwise have under this Agreement. (n) The Borrower shall, on the date of issuance or any extension or renewal of any Letter of Credit and at such other time or times as such charges are customarily made by the Issuing Bank, pay an upfront fee (in each case, a "Letter of Credit Fee") to the Administrative Agent in respect of each Performance Letter of Credit or Financial Letter of Credit so issued equal to the Letter of Credit Margin for such Performance Letter of Credit or Financial Letter of Credit, as the case may be, (the applicable basis points set forth on Schedule 2.07(b) computed on an annualized basis) plus a fronting fee for the benefit of the Issuing Bank equal to 12.5 basis points (computed on an annualized basis) plus the Issuing Bank's issuance, amendment and other administrative fees and charges customarily charged to its customers similarly situated. Such Letter of Credit Fee (but not such customary issuance, amendment fee or other administrative fees and charges, or the fronting fee, all of which shall be solely for the account of the Issuing Bank) shall be for the accounts of the Banks in accordance with their respective Commitment Percentages. Such upfront fees and fronting fees shall be based on a 360-day year, except that if the use of a 360-day 20 year would cause any such fees constituting interest (within the meaning of all applicable laws) to exceed the Highest Lawful Rate, then such interest and fees will be computed on the basis of a year of 365 days (or 366 in a leap year). SECTION 2.04. Notice to Banks; Funding of Loans. (a) Upon receipt of a Notice of Borrowing, the Administrative Agent shall promptly notify each Bank of the contents thereof and of such Bank's share (if any) of such Borrowing and such Notice of Borrowing shall not thereafter be revocable by the Borrower. (b) Not later than 12:00 Noon (Houston time) on the date of each Borrowing, each Bank participating therein shall (except as provided in subsection (c) of this Section) make available its share of such Borrowing, in funds immediately available in Houston, to the Administrative Agent at its address specified in or pursuant to Section 9.01. Unless the Administrative Agent determines that any applicable condition specified in Article III has not been satisfied, the Administrative Agent will make the funds so received from the Banks available to the Borrower at the Administrative Agent's aforesaid address. (c) If any Bank makes a new Loan hereunder on a day on which the Borrower is to repay all or any part of an outstanding Loan from such Bank, such Bank shall apply the proceeds of its new Loan to make such repayment and only an amount equal to the difference (if any) between the amount being borrowed and the principal amount being repaid shall be made available by such Bank to the Administrative Agent as provided in subsection (b), or remitted by the Borrower to the Administrative Agent as provided in Section 2.13, as the case may be. (d) Unless the Administrative Agent shall have received notice from a Bank prior to or on the date of any Borrowing that such Bank will not make available to the Administrative Agent such Bank's share of such Borrowing, the Administrative Agent may assume that such Bank has made such share available to the Administrative Agent on the date of such Borrowing in accordance with subsections (b) and (c) of this Section 2.04 and the Administrative Agent may, in reliance upon such assumption, make available to the Borrower on such date a corresponding amount. If and to the extent that such Bank shall not have so made such share available to the Administrative Agent, such Bank and the Borrower severally agree to repay to the Administrative Agent forthwith on demand such corresponding amount together with interest thereon, for each day from the date such amount is made available to the Borrower until the date such amount is repaid to the Administrative Agent, at (i) in the case of the Borrower, a rate per annum equal to the higher of the Federal Funds Rate and the interest rate applicable thereto pursuant to Section 2.07 and (ii) in the case of such Bank, the Federal Funds Rate. If such Bank shall repay to the Administrative 21 Agent such corresponding amount, such amount so repaid shall constitute such Bank's Loan included in such Borrowing for purposes of this Agreement. In no event shall any payment by the Administrative Agent, or repayment by the Borrower, of any amount pursuant to this subsection (d) relieve the Bank that failed to make available its share of the related Borrowing of its obligations hereunder. SECTION 2.05. Notes. (a) The Loans of each Bank shall be evidenced by a single Note payable to the order of such Bank for the account of its Applicable Lending Office in an amount equal to such Bank's Commitment. (b) Upon receipt of each Bank's Note pursuant to Section 3.01(viii), the Administrative Agent shall send by overnight mail such Note to such Bank. Each Bank shall record the date, amount and maturity of each Loan made by it and the date and amount of each payment of principal made by the Borrower with respect thereto, and prior to any transfer of its Note shall endorse on the schedule forming a part thereof appropriate notations to evidence the foregoing information with respect to each such Loan then outstanding; provided, however, that the failure of any Bank to make any such recordation or endorsement shall not affect the obligations of the Borrower hereunder or under the Notes. Each Bank is hereby irrevocably authorized by the Borrower so to endorse its Note and to attach to and make a part of its Note a continuation of any such schedule as and when required. SECTION 2.06. Maturity of Loans. Subject to any rights of the Borrower under Section 2.08, each Loan included in any Borrowing shall mature, and the principal amount thereof shall be due and payable, on the last day of the Interest Period applicable to such Borrowing. SECTION 2.07. Interest Rates. (a) Each Base Rate Loan shall bear interest on the outstanding principal amount thereof, for each day from the date such Loan is made until it becomes due, at a rate per annum equal to the Base Rate for such day (as described on Schedule 2.07(a)). Such interest shall be payable for each Interest Period on the last day thereof. Any overdue principal of and, to the extent permitted by law, overdue interest on any Base Rate Loan shall bear interest, payable on demand, for each day until paid at a rate per annum equal to the lesser of (i) the sum of 2 percent plus the rate otherwise applicable to Base Rate Loans for such day or (ii) the Highest Lawful Rate. (b) Each CD Loan shall bear interest on the outstanding principal amount thereof, for the Interest Period applicable thereto, at a rate per annum equal to the lesser of (i) the sum of the CD Margin (as in effect on the first day of such Interest Period) plus the applicable Adjusted CD Rate or (ii) the Highest Lawful Rate. Such interest shall be payable for each Interest Period on the last day thereof and, if such Interest Period is longer than 90 days, at intervals of 90 days after the first day 22 thereof. Any overdue principal of and, to the extent permitted by law, overdue interest on any CD Loan shall bear interest, payable on demand, for each day until paid at a rate per annum equal to the lesser of (i) the sum of 2 percent plus the rate applicable to Base Rate Loans for such day or (ii) the Highest Lawful Rate. "CD Margin" means the applicable basis points set forth in Schedule 2.07(c) hereto. The "Adjusted CD Rate" applicable to any Interest Period means a rate per annum determined pursuant to the following formula: [CDBR ]* ACDR = [-----------] + AR [1.00 - DRP] ACDR = Adjusted CD Rate CDBR = CD Base Rate DRP = Domestic Reserve Percentage AR = Assessment Rate - -------------------- * The amount in brackets being rounded upwards, if necessary, to the next higher 1/100 of 1 percent. The "CD Base Rate" applicable to any Interest Period is the rate of interest determined by the Administrative Agent to be the average (rounded upward, if necessary, to the next higher 1/100 of 1 percent) of the prevailing rates per annum (as determined by the CD Reference Banks as of approximately 9:00 a.m. on the preceding day) on the first day of such Interest Period paid by the CD Reference Banks on their respective certificates of deposit in an amount comparable to the unpaid principal amount of the CD Loan to which such Interest Period applies and having a maturity comparable to such Interest Period. "Domestic Reserve Percentage" means for any day that percentage (expressed as a decimal) which is in effect on such day, as prescribed by the Board of Governors of the Federal Reserve System (or any successor) for determining the maximum reserve requirement (including without limitation any basic, supplemental or emergency reserves) for a member bank of the Federal Reserve System in Dallas with deposits exceeding five billion dollars in respect of new non-personal time deposits in dollars in Dallas having a maturity comparable to the related Interest Period and in an amount of $100,000 or more. The Adjusted CD Rate shall be adjusted automatically on and as of the effective date of any change in the Domestic Reserve Percentage. 23 "Assessment Rate" means for any day the annual assessment rate in effect on such day which is payable by a member of the Bank Insurance Fund classified as well capitalized and within supervisory subgroup "B" (or a comparable successor assessment risk classification) within the meaning of 12 C.F.R. Section 327.3(d) (or any successor provision) to the Federal Deposit Insurance Corporation (or any successor) for such Corporation's (or such successor's) insuring time deposits at offices of such institution in the United States. The Adjusted CD Rate shall be adjusted automatically on and as of the effective date of any change in the Assessment Rate. (c) Each Euro-Dollar Loan shall bear interest on the outstanding principal amount thereof, for the Interest Period applicable thereto, at a rate per annum equal to the lesser of (i) the sum of the Euro-Dollar Margin (as in effect on the first day of such Interest Period) plus the Euro-Dollar Rate or (ii) the Highest Lawful Rate. Such interest shall be payable for each Interest Period on the last day thereof and, if such Interest Period is longer than three months, at intervals of three months after the first day thereof. "Euro-Dollar Margin" means the applicable basis points set forth in Schedule 2.07(d) hereto. "Euro-Dollar Rate" means, as to any Interest Period, the average (rounded upward, if necessary, to the next higher 1/16 of 1 percent) of the respective rates per annum at which deposits in dollars are offered to each of the Euro- Dollar Reference Banks by prime banks in whatever Euro-Dollar interbank market (or, in the case of 1-7 day Euro-Dollar Loans, the appropriate money markets) may be selected by the Euro-Dollar Reference Banks in their sole and absolute discretion, acting in good faith, at the time of determination and in accordance with the then usual practice in such market, at approximately 9:00 A.M. (Houston time) two Euro-Dollar Business Days before the first day of such Interest Period in an amount approximately equal to the principal amount of the Euro-Dollar Loan of such Reference Bank to which such Interest Period is to apply and for a period of time comparable to such Interest Period. (d) Any overdue principal of and, to the extent permitted by law, overdue interest on any Euro-Dollar Loan shall bear interest, payable on demand, for each day from and including the date payment thereof was due to but excluding the date of actual payment, at a rate per annum equal to the lesser of (i) the sum of 2 percent plus the rate applicable to Base Rate Loans for such day or (ii) the Highest Lawful Rate. (e) The Administrative Agent shall determine each interest rate applicable to the Loans hereunder. The Administrative Agent shall give prompt notice to the Borrower and the participating Banks by telecopy, telex or cable of each rate of 24 interest so determined, and its determination thereof shall be conclusive in the absence of manifest error. (f) Each Reference Bank agrees to use its best efforts to furnish quotations to the Administrative Agent as contemplated by this Section. If any Reference Bank does not furnish a timely quotation, the Administrative Agent shall determine the relevant interest rate on the basis of the quotation or quotations furnished by the remaining Reference Bank or Banks or, if none of such quotations is available on a timely basis, the provisions of Section 8.01 shall apply. SECTION 2.08. Conversions and Continuances. At the end of any Interest Period, the Borrower shall have the option to convert or continue all or a portion, equal to not less than $5,000,000 ($1,000,000 in the case of conversions or continuations into Base Rate Loans), of the outstanding principal amount of one Type of its Loans made pursuant to one or more Borrowings into a Borrowing or Borrowings of the other Type or Types of Loans; provided, however, that except as otherwise provided in Section 8.03, no partial conversion or continuation of Euro-Dollar Loans shall reduce the outstanding principal amount of Euro-Dollar Loans made pursuant to any single Borrowing to less than $5,000,000 and (ii) Base Rate Loans may be converted into CD Loans or Euro- Dollar Loans or continued as Base Rate Loans, and CD Loans and Euro-Dollar Loans may be continued as CD Loans or as Euro-Dollar Loans (as applicable) or converted into Base Rate Loans for additional Interest Periods if and only if, in either case no Default or Event of Default is in existence on the date of the conversion or continuation. Each such conversion or continuation shall be effected by the Borrower giving the Administrative Agent notice substantially in the form of Exhibit 2.08 (each a "Notice of Conversion") prior to 11:00 a.m. (Houston, Texas time) at least (a) three Euro-Dollar Business Days prior to the date of such conversion or continuation in the case of a conversion or continuation into Euro-Dollar Loans, (b) two Domestic Business Days in the case of a continuation or conversion into CD Loans and (c) one Domestic Business Day in the case of a conversion or continuation into Base Rate Loans, specifying each Type of Borrowing (or portions thereof) to be so converted or continued and, if to be converted or continued into CD Loans or Euro-Dollar Loans, the Interest Period to be initially applicable thereto. The Administrative Agent shall promptly give the Banks written or telephonic notice (promptly confirmed in writing) of any such proposed conversion or continuation affecting any of its Loans. SECTION 2.09. Pro Rata Borrowings. All Borrowings under this Agreement shall be incurred from the Banks ratably in proportion to their respective Commitments. It is understood that no Bank shall be responsible for any default by any other Bank in its obligation to make Loans hereunder and that each Bank shall be obligated to make the Loans provided to be made by it hereunder, regardless of the failure of any other Bank to fulfill its Commitment hereunder. 25 SECTION 2.10. Optional Termination or Reduction of Commitments. The Borrower may, upon at least three Domestic Business Days' notice to the Administrative Agent, (i) terminate the Commitments at any time, if no Loans or Letters of Credit are outstanding at such time or (ii) ratably reduce from time to time by an aggregate amount of $10,000,000 or any larger multiple of $1,000,000, the aggregate amount of the Commitments in excess of the sum of the aggregate outstanding principal amount of the Loans plus the Letter of Credit Outstandings; provided, however, that if no Loans are then outstanding, the Borrower may terminate the Commitments at any time when there are outstanding Letters of Credit by depositing with the Administrative Agent such amount of cash as is equal to the aggregate Stated Amount of the Letters of Credit then outstanding to be held in an interest bearing account with the Administrative Agent, all such cash and interest to be held by the Administrative Agent as security for the obligations of the Borrower in respect of such Letters of Credit; provided further, that the Borrower shall remain liable for any expenses and other liabilities in respect of such Letters of Credit on terms consistent with Section 9.04, but for all other purposes of this Agreement and the other Loan Documents the Obligations will be deemed paid in full and not outstanding. Any reduction of the Commitments shall apply proportionately to the Commitment of each Bank in accordance with its Commitment Percentage and any such reduction shall be permanent. SECTION 2.11. Mandatory Termination of Commitments. The Commitment of each Bank shall terminate on the Termination Date, and all Loans then outstanding (together with accrued interest thereon) shall be due and payable on such date; provided, however, if there are any Letter of Credit Outstandings or unpaid Loans on the Termination Date, all obligations of the Borrower and all rights and remedies of the Banks hereunder shall continue, subject to the provisos of Section 2.10, until the full and final repayment thereof. SECTION 2.12. Optional Prepayments. (a) The Borrower may, upon at least one Domestic Business Day's notice to the Administrative Agent, prepay any Base Rate Borrowing (or any other Borrowing bearing interest at the Base Rate pursuant to Article VIII) or, subject to Section 2.14 and upon at least three Euro-Dollar Business Days' notice to the Administrative Agent, prepay any Fixed Rate Borrowing, in whole at any time, or from time to time in part in amounts aggregating $10,000,000 or any larger multiple of $1,000,000, by paying the principal amount to be prepaid together with accrued interest thereon to but excluding the date of prepayment. Each such optional prepayment shall be applied to prepay ratably the Loans of the several Banks included in such Borrowing. (b) Upon receipt of a notice of prepayment pursuant to this Section, the Administrative Agent shall promptly notify each Bank of the contents thereof and of 26 such Bank's ratable share (if any) of such prepayment and such notice shall not thereafter be revocable by the Borrower. SECTION 2.13. General Provisions as to Payments. (a) The Borrower shall make each payment of principal of, and interest on, the Loans and of fees hereunder, not later than 12:00 Noon (Houston time) on the date when due, in Federal or other funds immediately available in Houston, Texas, to the Administrative Agent at its address referred to in Section 9.01. The Administrative Agent will promptly distribute to each Bank its ratable share, if any, of each such payment received by the Administrative Agent for the account of the Banks. Whenever any payment of principal of, or interest on, the Domestic Loans or of fees shall be due on a day which is not a Domestic Business Day, the date for payment thereof shall be extended to the next succeeding Domestic Business Day. Whenever any payment of principal of, or interest on, the Euro-Dollar Loans shall be due on a day which is not a Euro-Dollar Business Day, the date for payment thereof shall be extended to the next succeeding Euro- Dollar Business Day unless such Euro-Dollar Business Day falls in another calendar month, in which case the date for payment thereof shall be the next preceding Euro-Dollar Business Day. If the date for any payment of principal is extended by operation of law or otherwise, interest thereon shall be payable for such extended time. (b) Unless the Administrative Agent shall have received notice from the Borrower prior to the date on which any payment is due to the Banks hereunder that the Borrower will not make such payment in full, the Administrative Agent may assume that the Borrower has made such payment in full to the Administrative Agent on such date and the Administrative Agent may, in reliance upon such assumption, cause to be distributed to each Bank on such due date an amount equal to the amount then due such Bank. If and to the extent that the Borrower shall not have so made such payment, each Bank shall repay to the Administrative Agent forthwith on demand such amount distributed to such Bank together with interest thereon, for each day from the date such amount is distributed to such Bank until the date such Bank repays such amount to the Administrative Agent, at the Federal Funds Rate. SECTION 2.14. Funding Losses. The Borrower shall pay to the Administrative Agent for the account of each Bank, upon the request of such Bank through the Administrative Agent, such amount or amounts as shall compensate such Bank for any reasonable loss, cost or expense actually incurred by such Bank (or, subject to Section 9.07(b), by any existing Participant in the related Loan) as a result of: (a) any payment or prepayment of a Fixed Rate Loan (pursuant to Section 2.12 or Article VI or VIII or otherwise) held by such Bank (or 27 such Participant) on a date other than the last day of the Interest Period applicable thereto, or (b) any failure by the Borrower to borrow a Fixed Rate Loan held or to be held by such Bank (or such Participant) on the date for such Borrowing specified in the relevant Notice of Borrowing, such compensation to include, without limitation, an amount equal to the excess, if any, of (i) the amount of interest which would have accrued on the amount so paid or prepaid, or not converted or borrowed, for the period from the date of such payment or prepayment or failure to borrow or convert to the last day of such Interest Period (or, in the case of a failure to borrow, the Interest Period for such Fixed Rate Loan which would have commenced on the date of such failure to convert or borrow) in each case at the applicable rate of interest for such Fixed Rate Loan provided for herein (excluding, however, the CD Margin or the Euro-Dollar Margin included therein) over (ii) the amount of interest (as reasonably determined by such Bank or Participant) which would have accrued to such Bank or Participant on such amount by placing such amount on deposit for a comparable period with leading banks in the relevant interbank market; provided, however, that such Bank shall have delivered to the Borrower, within 60 days after the date of such payment or prepayment or failure to borrow, a certificate as to the amount of such actual loss or expense, which certificate shall set forth in reasonable detail the basis for such loss or expense and shall be conclusive in the absence of manifest error. Any payment required to be made pursuant to this Section 2.14 shall be made within 5 days after receipt of the certificate referred to above. SECTION 2.15. Fees. (a) Commitment Fee. The Borrower shall pay to the Administrative Agent for the account of the Banks ratably in proportion to their Commitments a commitment fee equal to the highest applicable basis points set forth in Schedule 2.15 calculated on the daily average amount by which the aggregate amount of the Commitments exceeds the sum of (i) the Letter of Credit Outstandings and (ii) the aggregate outstanding principal amount of the Loans. Such commitment fee shall accrue for the account of each Bank from and including the Effective Date to but excluding the Termination Date. (b) Payments. Accrued fees under this Section and Section 2.03 for the account of any Bank shall be payable quarterly in arrears on each March 31, June 30, September 30 and December 31 and upon the Termination Date. SECTION 2.16. Computation of Interest and Fees. Interest based on the Prime Rate shall be computed on the basis of a year of 365 days (or 366 days in a leap year) 28 and paid for the actual number of days elapsed (including the first day but excluding the last day). All other interest and all fees shall be computed on the basis of a year of 360 days and paid for the actual number of days elapsed (including the first day but excluding the last day) except that if use of a 360-day year would cause any interest or fees constituting interest (within the meaning of all applicable laws) to exceed the Highest Lawful Rate, then such interest and fees will be computed on the basis of a year of 365 days (or 366 in a leap year). SECTION 2.17. Maximum Interest Rate. (a) It is the intention of the parties hereto to comply strictly with all applicable usury laws regarding the contracting for, and the taking, reserving, charging, collection, payment and receipt of, interest (which shall, for purposes of this Section 2.17, be deemed to include, without limitation, any compensation received by any Agent or any Bank for the use, forbearance or detention (as such terms are used in Tex. Rev. Civ. Stat. Ann. Art. 5069-1.01(a)) of the indebtedness incurred under this Agreement and the Notes) whether such laws are now or hereafter in effect, including the laws of the United States of America or any other jurisdiction whose laws are applicable, and including any subsequent revisions to or judicial interpretations of those laws, in each case to the extent they are applicable to this Agreement and the Notes (the "Applicable Usury Laws"). (b) If any payment by the Borrower or any other Person to any Agent or any Bank hereunder (including any payment upon acceleration of the maturity of any Notes of such Bank) would produce a rate of interest in excess of the Highest Lawful Rate, as defined in paragraph (e) below, with respect to any Bank, or otherwise result in the Borrower or any other Person paying or being deemed to have paid to any Agent or any Bank any interest in excess of the Maximum Amount, as defined in subsection (e) below, with respect to any Bank, or if any Agent or any Bank shall for any reason receive any unearned interest in violation of any Applicable Usury Law, or if any transaction contemplated by or any provision of this Agreement, any Bank's Note or Notes, any Letter of Credit Application or any other agreement or instrument (collectively, such Bank's "Loan Documents") would otherwise be usurious under any Applicable Usury Laws, then, notwithstanding anything to the contrary in any Bank's Loan Documents, the parties hereto agree as follows: (i) the provisions of this Section 2.17 shall govern and control; (ii) the aggregate amount of all interest under Applicable Usury Laws that is contracted for, taken, reserved, charged, collected or received pursuant to each Bank's Loan Documents or otherwise shall under no circumstances exceed the Maximum Amount; (iii) neither the Borrower nor any other Person shall be obligated to pay the amount of such interest to the extent that it exceeds the Maximum Amount; and (iv) the provisions of each Bank's Loan Documents immediately shall be deemed reformed, without the necessity of the execution of any new document or instrument, so as to comply with all Applicable Usury Laws, it being the intention of the parties, to the fullest extent permitted by law, to render 29 inapplicable any and all penalties of any kind provided by any Applicable Usury Law as a result of any such excess interest. (c) If any payment by the Borrower or any other Person under any Bank's Loan Documents (including any payment upon acceleration of the maturity of any Note) results in the Borrower actually having paid to such Bank or any Agent any interest in excess of the Maximum Amount, then such excess amount shall be applied to the reduction of the principal balance of such Bank's Loans or to other amounts (other than interest) payable hereunder, and if no such principal is then outstanding, and no such other amount is then payable, such excess or part thereof remaining, shall be repaid to the Borrower or such other Person. (d) All interest paid, or agreed to be paid, pursuant to any Bank's Loan Documents shall, to the fullest extent permitted by Applicable Usury Laws, be amortized, prorated, allocated and spread throughout the full term of any indebtedness incurred under or evidenced by such Bank's Loan Documents. (e) As used herein, the term "Maximum Amount" means, with respect to any Bank, in any of such Bank's capacities hereunder, the maximum nonusurious amount of interest that may be lawfully contracted for, reserved, charged, collected or received (in each case as determined by the Applicable Usury Laws) by such Bank in connection with the indebtedness incurred under or evidenced by such Bank's Loan Documents under all Applicable Usury Laws, and the term "Highest Lawful Rate" means, with respect to any Bank, on any day, the maximum rate of interest, if any, that may be contracted for, taken, reserved, charged, collected or received under all Applicable Usury Laws on the principal balance of the indebtedness incurred under or evidenced by such Bank's Loan Documents from time to time outstanding. In this connection, for purposes of Tex. Rev. Civ. Stat. Ann. Art. 5069-1.04, as it may from time to time be amended, the Highest Lawful Rate, to the extent it is determined with reference thereto, shall be the "indicated rate ceiling" from time to time in effect, referred to in, and determined pursuant to Section (a)(1) of such Art. 5069-1.04, as amended, as modified by Section (b) of such Art. 5069-1.04; provided, however, that to the fullest extent permitted by all Applicable Usury Laws, each Agent and each Bank reserves the right to change, from time to time, in accordance with such Art. 5069-1.04, by written notice to the Borrower, the ceiling upon which the Highest Lawful Rate is based under such Art. 5069-1.04 to the extent it is based thereon; provided further, that the Highest Lawful Rate shall not be limited to the applicable rate ceiling under such Art. 5069-1.04 if applicable federal laws or state laws now or hereafter in effect shall permit a higher rate of interest to be contracted for, taken, reserved, charged, collected and received under any Bank's Loan Documents. (f) In the event that any rate of interest set forth in Sections 2.07 and 8.01 on any Loan of any Bank (a "Stated Rate"), together with any fees or other amounts 30 payable under such Bank's Loan Documents to any Agent or such Bank, in any of such Bank's capacities hereunder, deemed to constitute interest under Applicable Usury Laws ("Additional Interest"), exceeds the Highest Lawful Rate, then the amount of interest payable to such Bank to accrue pursuant to such Bank's Loan Documents shall be limited, notwithstanding anything to the contrary in such Bank's Loan Documents, to the amount of interest that would accrue at the Highest Lawful Rate; provided, however, that, to the fullest extent permitted by Applicable Usury Laws, any subsequent reductions in any Stated Rate shall not reduce the interest payable to such Bank to accrue pursuant to such Bank's Loan Documents below the Highest Lawful Rate until the aggregate amount of interest payable to such Bank actually accrued pursuant to such Bank's Loan Documents, together with all Additional Interest payable to such Bank, equals the amount of interest which would have accrued if the Stated Rates had at all times been in effect and such Additional Interest, if any, had been paid in full. (g) In the event that, at maturity or upon payment in full of all amounts payable under any Bank's Loan Documents, the total amount of interest paid or payable to any Agent or any Bank, in any of such Bank's capacities hereunder, and accrued under the terms of or evidenced by such Bank's Loan Documents is less than the total amount of interest which would have been paid or accrued on the indebtedness incurred under or evidenced by such Bank's Loan Documents if the Stated Rates had, at all times, been in effect and all Additional Interest had been paid in full, then the Borrower shall, to the extent permitted by Applicable Usury Laws, pay to the Administrative Agent for the account of such Bank an amount equal to the difference between (1) the lesser of (i) the amount of interest payable to such Bank which would have accrued if the Highest Lawful Rate for such Bank had at all times been in effect or (ii) the amount of interest which would have accrued on the indebtedness incurred under or evidenced by such Bank's Loan Documents if the Stated Rates had at all times been in effect and all Additional Interest had been paid in full and (2) the amount of interest actually paid to such Bank or payable to such Bank and accrued under or evidenced by such Bank's Loan Documents. (h) The Borrower, the Agents and the Banks agree that, except for Article 15.10(b) thereof, the provisions of Chapter 15, Subtitle 79, Revised Civil Statutes of Texas, 1925, as amended (which regulates certain revolving credit loan accounts and revolving tri-party accounts), do not apply to this Agreement or any of the Notes or any of the Obligations. SECTION 2.18. Withholding Tax Exemption. At least five Domestic Business Days prior to the first date on which interest or fees are payable hereunder for the account of any Bank, each Bank that is not incorporated under the laws of the United States of America or a state thereof agrees that it will deliver to each of the Borrower and the Administrative Agent two duly completed copies of United States Internal 31 Revenue Service Form 1001 or 4224, certifying in either case that such Bank is entitled to receive payments under this Agreement and the Notes without deduction or withholding of any United States federal income taxes. Each Bank which so delivers a Form 1001 or 4224 further undertakes to deliver to each of the Borrower and the Administrative Agent two additional copies of such form (or a successor form) on or before the date that such form expires or becomes obsolete or after the occurrence of any event requiring a change in the most recent form so delivered by it, and such amendments thereto or extensions or renewals thereof as may be reasonably requested by the Borrower or the Administrative Agent, in each case certifying that such Bank is entitled to receive payments under this Agreement and the Notes without deduction or withholding of any United States federal income taxes, unless 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 Bank from duly completing and delivering any such form with respect to it and such Bank advises the Borrower and the Administrative Agent that it is not capable of receiving payments without any deduction or withholding of United States federal income tax. Any Bank that is not capable of receiving payments without any deduction or withholding of United States federal income tax will promptly notify the Borrower and the Administrative Agent to that effect and will designate a different Applicable Lending Office if such designation will render such Bank capable of receiving payments without any such deduction or withholding and will not, in the reasonable judgment of such Bank, be otherwise disadvantageous. If the Borrower shall receive a certificate of such Bank claiming the need for deductions or withholdings under this Section 2.18, the Borrower shall, subject to Section 8.06 hereof, commence making any deductions and withholding any amounts with respect to payments for the account of such Bank that are required by applicable law. ARTICLE III CONDITIONS SECTION 3.01. Effectiveness.

The Administrative Agent shall promptly notify the Borrower and the Banks of the Effective Date, and such notice shall be conclusive and binding on all parties hereto. The Administrative Agent shall promptly forward to the Banks copies of the documents delivered pursuant to this Section 3.01. SECTION 3.02. Credit Events.

Each Credit Event hereunder shall be deemed to be a representation and warranty by the Borrower on the date of such Borrowing as to the facts specified in clauses (ii), (iii) and (iv) of this Section. 34 ARTICLE IV REPRESENTATIONS AND WARRANTIES SECTION 4.01.

(i) in addition to its obligations pursuant to Section 2.02, prompt written notice of any Debt, other than Borrowings, incurred subsequent to the Effective Date; and 41 (j) from time to time such further information regarding compliance with this Agreement or the business, operations, affairs, assets, condition (financial or otherwise) or results of operations of the Borrower and its Consolidated Subsidiaries as the Administrative Agent, at the request of any Bank, may reasonably request.

To the extent, if any, that the following Liens would otherwise be prohibited by the foregoing provisions, the foregoing provisions shall not apply to: (a) Liens on any property of a corporation or other Person existing at the time it becomes a Subsidiary or at the time it is merged into or consolidated with the Borrower or a Subsidiary and not created in contemplation of such event;

(g) Liens required by any contract or statute in order to permit the Borrower or a Subsidiary to perform any contract or subcontract made by it with or at the request of the United States of America, any state or any department, agency or instrumentality or political subdivision of either; or (h) Liens securing taxes, assessments, governmental charges or levies, statutory Liens of landlords and Liens of carriers, warehousemen, materialmen, mechanics and other like Persons not yet due or the payment of which is not then required;

provided, however, that any obligation secured by any such Lien shall not be overdue or, if overdue, is being contested in good faith by appropriate actions or proceedings during which there is no right to exercise remedies and adequate book reserves have been established; provided further, that paragraph (j) shall not be deemed to permit any Liens which may be imposed pursuant to Section 4068 of ERISA; (k) Minor survey exceptions and minor encumbrances, easements or reservations, or rights of others for rights-of-way, utilities and other similar purposes, or zoning or other restrictions as to the use of real properties, which are necessary for the conduct of the activities of Borrower or any Subsidiary or which customarily exist on properties of corporations or other Persons engaged in similar activities and similarly situated; (l) any extension, renewal or replacement (or successive extensions, renewals or replacements), in whole or in part, of any Lien referred to in the foregoing paragraphs (a) to (k) inclusive or of any Debt secured thereby, provided that the principal amount of Debt secured thereby shall not exceed the principal amount of Debt so secured at the time of such extension, renewal or replacement, and that such extension, renewal or replacement Lien shall be limited to all or part of substantially the same property which secured the Lien extended, renewed or replaced (plus improvements on such property); provided, however, that the Borrower and any one or more Restricted Subsidiaries may issue, assume or guarantee Debt secured by Liens which would otherwise be subject to the foregoing restrictions or grant any such Lien to secure any such Debt in an aggregate principal amount which, together with the aggregate outstanding principal amount of all Debt of the Borrower and the Restricted Subsidiaries which would otherwise be subject to the foregoing restrictions (not including Debt permitted to be secured under paragraphs (a) to (l) inclusive above), does not at any one time exceed the greater of $50,000,000 or 10 percent of Consolidated Net Tangible Assets of the Borrower and its Consolidated Subsidiaries. SECTION 5.04. Consolidation, Merger, Disposition of Assets. (a) Subject to the provisions of Section 5.04(b) hereof, nothing contained in this Agreement shall prevent any consolidation or merger of the Borrower with or into any other corporation or corporations (whether or not affiliated with the Borrower), or successive consolidations or mergers in which the Borrower or its successor or successors shall be a party or parties, or shall prevent any sale or conveyance of all or substantially all the property of the Borrower, to any other Person (whether or not affiliated with the Borrower) authorized to acquire and operate the same; provided, however, that upon any such consolidation, merger, sale or conveyance, other than a consolidation or merger in which the Borrower is the continuing corporation, the surviving entity must 44 be chartered under the laws of the United States or one of its states and the due and punctual payment of the principal of and interest on all of the Notes, according to their tenor, and the due and punctual performance and observance of all of the covenants and conditions of this Agreement, shall be expressly assumed by instrument reasonably satisfactory in form to the Required Banks and executed and delivered to the Administrative Agent by the corporation (if other than the Borrower) formed by such consolidation or into which the Borrower shall have been merged or by the Person which shall have acquired such property; and provided further that no Default or Event of Default shall exist hereunder after giving effect to such consolidation, merger or sale of assets. (b) If, upon any consolidation or merger of the Borrower with or into any other corporation, or upon the sale or conveyance of all or substantially all the property of the Borrower to any other Person or if any of the remaining property of the Borrower or of any Restricted Subsidiary would thereupon become subject to any Lien, the Borrower, prior to or simultaneously with such consolidation, merger, sale or conveyance, will secure the Notes, the Letter of Credit Outstandings and all other obligations of the Borrower under this Agreement equally and ratably with any other obligations of the Borrower (or any Restricted Subsidiary if applicable) then entitled thereto, by a direct Lien on all such property prior to all Liens other than any theretofore existing thereon. SECTION 5.05. Use of Proceeds. The proceeds of the Loans made and Letters of Credit issued under this Agreement will be used by the Borrower and its Subsidiaries for general business purposes. None of such proceeds will be used in violation of Regulation U, Regulation X, Regulation G or of any similar laws or regulations. SECTION 5.06. Payment of Taxes.

LCR Matters. (a) The Borrower will cause LRC to not permit any amendment or modification to the Company Regulations, or take any other action, that would in each case result in LRC's Participation Percentage (as defined in the Company Regulations) to be less that 50 percent, without the consent of Banks having at least 70 percent of the aggregate amount of the Commitments. (b) Unless the Banks having at least 70 percent of the aggregate Commitments agree otherwise, the Borrower shall cause LRC (within the bounds of good business judgment and its legal obligations under or in connection with the Company Regulations), as an Owner of LCR, to withhold its consent, which is required under Section 3.8 of the Company Regulations, with respect to any action that would cause or permit LCR (or any Person acting in the name or on behalf of LCR), directly or indirectly, to undertake any of the following: (1) to incur Debt; provided, however, that this covenant shall not be applicable to (i) any Debt for which the Borrower or LRC is the obligee, (ii) any Debt resulting from the Credit Agreement dated as of July 1, 1993 (as the same may be amended or otherwise modified from time to time) between LCR and Continental Bank N.A. as Agent, or any renewal or replacement of such Credit Agreement; provided, however, that such renewal or replacement does not result in an increase in the aggregate principal amount of such credit facility, (iii) any Debt which CITGO Refining is contractually or otherwise liable to pay or to provide reimbursement for pursuant to the Company Regulations, as the same may be amended or otherwise modified from time to time, or (iv) any Debt that is non-recourse to the Borrower and LRC either existing on the In-Service Date (as defined in the Company Regulations) or incurred by LCR subsequent to the In-Service Date; (2) to fail to maintain insurance consistent either with the insurance practices of the Borrower and its Subsidiaries in effect on the date hereof or with then existing industry practice, in either case to the extent available to LCR on commercially reasonable terms; and (3) to amend, or alter the Company Regulations in any way that would materially adversely affect (i) the Borrower's access to its share of distributable cash from LCR or (ii) other material rights and obligations of the Borrower or LRC under the Company Regulations (including without limitation materially increasing an obligation of the Borrower or LRC to make contributions to LCR or materially decreasing an obligation of CITGO or CITGO Refining to make contributions to LCR), provided, however, that in any event the Borrower will 46 provide promptly thereafter to the Administrative Agent notice and copies of all amendments to the Company Regulations. SECTION 5.08. Financial and Other Covenants. The Borrower will comply with the covenants described in this Section. a. Debt Incurrence Test. If the aggregate outstanding principal amount of all Debt of the Borrower and its Consolidated Subsidiaries incurred subsequent to the Effective Date exceeds $75,000,000, then the Borrower and its Subsidiaries will not be permitted to incur any additional Debt unless, after giving effect thereto, the ratio of EBITDA to Consolidated Interest Expense, for the four-fiscal-quarter period most recently ended, is greater than or equal to the ratio set forth below with respect to the period that includes the last quarter of such four-fiscal-quarter period; provided, however, that each such determination shall be made by giving effect to all Debt of the Borrower and its Consolidated Subsidiaries actually outstanding during any portion of such four- fiscal-quarter period and by assuming that such proposed Debt had been incurred on the first day of such four-fiscal-quarter period: Period Ratio - ---------- --------- From the Effective Date 1.75 to 1 through December 31, 1994 From January 1, 1995 2.00 to 1 through December 31, 1995 Thereafter 2.25 to 1 b. Fixed Charge Coverage Ratio. The Borrower will not permit, as of the end of any fiscal quarter, the ratio of (i) EBITDA less Consolidated Capital Expenditures (provided, however, that in determining Consolidated Capital Expenditures for purposes of this covenant all items attributable to the activities or business of LCR shall be excluded), to (ii) Consolidated Interest Expense, computed in each case for the four-fiscal-quarter period ending during each of the following periods, to be less than the designated ratio set forth below with respect to each such period: Period Ratio - ------- --------- From the Effective Date 1.15 to 1 through December 31, 1994 From January 1, 1995 1.30 to 1 through December 31, 1995 Thereafter 2.00 to 1 c. Leverage Ratio. The Borrower will not permit, as of the end of any fiscal quarter, the ratio of Consolidated Debt to EBITDA, computed in each case for the four- 47 fiscal-quarter period ending during each of the following periods, to be greater than the designated ratio set forth below with respect to each such period: Period Ratio - ------ --------- From the Effective Date 6.50 to 1 through December 31, 1994 From January 1, 1995 5.50 to 1 through December 31, 1995 From January 1, 1996 4.50 to 1 through December 31, 1996 Thereafter 4.00 to 1 d. Dividend Payments. The Borrower will not at any time declare, make or pay, or incur any liability to make or pay, or cause or permit to be declared, made or paid any Dividend unless at the time of declaring such Dividend, and after giving effect thereto, the aggregate amount of all such Dividends declared or paid on or after January 1, 1994 shall not exceed an amount equal to the sum of $72,000,000 plus 100 percent of Consolidated Net Income or Loss, excluding non-cash Non-Operating Special Items used in determining Consolidated Net Income or Loss, for the period commencing October 1, 1993 and ending with the most recently completed fiscal quarter of the Borrower. e. Restricted LCR Investments. From and after the Effective Date, the aggregate of all Investments shall not exceed $200,000,000; provided, however, that the Borrower or LRC may invest in LCR, in excess of such $200,000,000, all or a portion of the proceeds from any capital markets offering consisting solely of equity securities. f. Methodology for Determining Covenant Compliance. Notwithstanding any contrary provision of this Agreement, the Borrower's compliance with each of the covenants described in this Section shall be determined in accordance with the following methodology: (1) All calculations shall be made without taking into account any Debt or Interest Expense of LCR or CITGO Refining, or any Debt or Interest Expense which CITGO Refining, pursuant to the Company Regulations as the same may be amended or otherwise modified from time to time, is contractually or otherwise liable to pay or provide reimbursement for; (2) In the event the Borrower issues Debt ("Replacement Debt") for the purpose of refinancing Debt outstanding under any of the Borrower's public indentures or medium-term note programs ("Replaced Debt"), the aggregate principal amount of such Replacement Debt shall be substituted in place of the Replaced Debt for purposes of all determinations and the calculations, in 48 paragraphs (a) and (c) of this Section; provided, however, that the Net Interest associated with such Replacement Debt shall be included in Interest Expense for purposes of the calculation in paragraph (b) of this Section; and further provided, that the treasurer of the Borrower shall certify to the Administrative Agent that such Replacement Debt will be used to refinance Replaced Debt. (3)(A) From the Effective Date until the Borrower's public announcement of its Consolidated Net Income or Loss for the fiscal quarter ended June 30, 1994, the results of operations for, and all information pertaining to, the Borrower's most recently completed quarter or four- fiscal-quarter period, as applicable, shall be determined by converting to an annualized four-fiscal-quarter period, information publicly announced by the Borrower as its Consolidated Net Income or Loss for the most recent three month, six month or nine month period, as available, from and including the fiscal quarter ended September 30, 1993; and (3)(B) From the date of the Borrower's public announcement of its Consolidated Net Income or Loss for the fiscal quarter ended June 30, 1994 and during the remainder of the term of this Agreement, the results of operations for, and all information pertaining to, the Borrower's most recently completed quarter or four-fiscal-quarter period, as applicable, shall be determined based upon the last quarter, or the four-fiscal-quarter period (the last quarter of which is the most recent quarter), for which the Borrower has made a public announcement of its Consolidated Net Income or Loss. ARTICLE VI DEFAULTS AND REMEDIES SECTION 6.01. Defaults.

SECTION 7.08. Successor Agents. Either of the Agents may resign at any time by giving written notice thereof to the Banks and the Borrower, with such resignation to be effective upon the acceptance by a successor Agent of its appointment as agent hereunder, as set forth below.

Basis for Determining Interest Rate Inadequate or Unfair. If on or prior to the first day of any Interest Period for any Fixed Rate Borrowing: (1) the Administrative Agent is advised by the Reference Banks that deposits in dollars (in the applicable amounts) are not being offered to the Reference Banks in the relevant market for such Interest Period, or (2) the Required Banks advise the Administrative Agent that the Adjusted CD Rate or the Euro-Dollar Rate, as the case may, as determined by the Administrative Agent will not adequately and fairly reflect the cost to such Banks of funding their Fixed Rate Loans for such Interest Period, the Administrative Agent shall forthwith give notice thereof to the Borrower and the Banks, whereupon until the Administrative Agent notifies the Borrower that the circumstances giving rise to such notice no longer exist: (A)(i) if such circumstances relate to CD Loans, the obligations of the Banks to make CD Loans shall be suspended or (ii) if such circumstances relate to the Euro-Dollar Loans, the obligations of the Banks to make Euro-Dollar Loans shall be suspended and (B) unless the Borrower notifies the Administrative Agent at least one Domestic Business Day before the date of any Fixed Rate Borrowing for which a Notice of Borrowing has previously been given that it elects not to borrow on such date, (i) if such Fixed Rate Borrowing is a CD Borrowing, such CD Borrowing shall instead be made (x) as a Euro-Dollar Borrowing if the Borrower so elects by notice to the Administrative Agent and all of the procedures set forth herein for a Euro-Dollar Borrowing can be complied with at such time or (y) if a Euro-Dollar Borrowing is not possible, then such CD Borrowing shall instead be made as a Base Rate Borrowing, and (ii) if such Fixed Rate Borrowing is a Euro-Dollar Borrowing, such Euro-Dollar Borrowing shall be made (x) as a CD Borrowing if the Borrower so elects by notice to the Administrative Agent and all of the procedures set forth herein for a CD Borrowing can be complied with at such time or (y) if a CD Borrowing is not elected or is not possible, then such Euro- Dollar Borrowing shall instead be made as a Base Rate Borrowing. SECTION 8.02. Illegality. If, after the Effective Date, the adoption of any applicable law, rule or regulation, or any change therein, or any change in the 55 interpretation or administration thereof by any governmental authority, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by any Bank (or its Euro-Dollar Lending Office) with any request or directive (whether or not having the force of law) of any such authority, central bank or comparable agency shall make it unlawful or impossible for any Bank (or its Euro-Dollar Lending Office) to make, maintain or fund its Euro-Dollar Loans and such Bank shall so notify the Administrative Agent, the Administrative Agent shall forthwith give notice thereof to the other Banks and the Borrower whereupon until such Bank notifies the Borrower and the Administrative Agent that the circumstances giving rise to such suspension no longer exist (which such Bank shall do forthwith) the obligation of such Bank to make Euro-Dollar Loans shall be suspended. Before giving any notice to the Administrative Agent pursuant to this Section, such Bank shall designate a different Euro-Dollar Lending Office if such designation will avoid the need for giving such notice and will not, in the reasonable judgment of such Bank, be otherwise disadvantageous to such Bank. If such Bank shall determine that it may not lawfully continue to maintain and fund any of its outstanding Euro- Dollar Loans to maturity and shall so specify in such notice, the Borrower shall immediately prepay in full the then outstanding principal amount of each such affected Euro-Dollar Loan, together with accrued interest thereon. Concurrently with prepaying each such affected Euro-Dollar Loan, the Borrower shall borrow a Base Rate Loan (or, if the Borrower so elects by at least one Domestic Business Day's notice to the Administrative Agent and such Bank, the Borrower shall borrow a CD Loan from such Bank in a principal amount equal to the principal amount of such affected Euro-Dollar Loan for an Interest Period coincident with the remaining term of the Interest Period applicable to such affected Euro- Dollar Loan of the Borrower, and such Bank shall make such a Base Rate (or other) Loan. SECTION 8.03. Increased Cost and Reduced Return. (a) If on or after the Effective Date, in the case of any Loan or any obligation to make Loans or any obligations to issue or participate in any Letters of Credit, the adoption of any applicable law, rule or regulation, or any change therein, or any change in the interpretation or administration thereof by any governmental authority, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by any Bank (or its Parent or Applicable Lending Office) with any request or directive (whether or not having the force of law) of any such authority, central bank or comparable agency: (i) shall subject any Bank (or its Applicable Lending Office) to any tax, duty or other charge with respect to its Fixed Rate Loans or participation in Letters of Credit, its Notes or its obligation to make Fixed Rate Loans or issue Letters of Credit, or shall change the basis of taxation of payments to any Bank (or its Applicable Lending Office) of the principal of or interest on its Fixed Rate Loans or Letters of Credit or any other amounts due under this Agreement in 56 respect of its Fixed Rate Loans or Letters of Credit or its obligation to make Fixed Rate Loans or issue or participate in Letters of Credit (except for changes in the rate of tax on the income of such Bank or its Applicable Lending Office or changes in franchise taxes imposed on it under applicable law); or (ii) shall impose, modify or deem applicable any reserve, special deposit, deposit insurance assessment or similar requirement (including, without limitation, any such requirement imposed by the Board of Governors of the Federal Reserve System, but excluding (A) with respect to any CD Loan any such requirement included in an applicable Domestic Reserve Percentage and (B) with respect to any Euro-Dollar Loan any such requirement with respect to which such Bank is entitled to compensation during the relevant Interest Period under Section 8.05) against assets of, deposits with or for the account of, or credit extended by, any Bank (or its Applicable Lending Office) or shall impose on any Bank (or its Applicable Lending Office) or on the United States market for certificates of deposit or the London interbank market any other condition affecting its Fixed Rate Loans, its Notes or its obligation to make Fixed Rate Loans; and the result of any of the foregoing is to increase the actual cost to such Bank (or its Applicable Lending Office) of making or maintaining any Fixed Rate Loan or issuing or participating in any Letter of Credit, or to reduce the amount of any sum received or receivable by such Bank (or its Applicable Lending Office) under this Agreement or under its Notes with respect thereto, by an amount reasonably deemed by such Bank to be material, then, within 15 days after demand by such Bank (with a copy to the Administrative Agent), the Borrower shall pay to such Bank (without duplication of amounts otherwise payable hereunder) such additional amount or amounts as will compensate such Bank for such increased cost or reduction with respect to such affected Fixed Rate Loan or Letter of Credit or such affected sum. (b) If any Bank shall have reasonably determined that the adoption of any applicable law, rule or regulation regarding capital adequacy or any change therein, or any change in the interpretation or administration thereof by any governmental authority, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by any Bank (or its Parent or Applicable Lending Office) with any request or directive regarding capital adequacy (whether or not having the force of law) of any such authority, central bank or comparable agency, has or has had the effect of reducing the rate of return on capital of such Bank (or its Parent) as a consequence of such Bank's obligations hereunder to a level below that which such Bank or its Parent could have achieved but for such adoption, change or compliance (taking into consideration such Bank's policies with respect to capital adequacy) by an amount deemed by such Bank to be material, then from time to time, within 15 days after demand by such Bank (with a copy to the Administrative Agent), the 57 Borrower shall pay to such Bank (without duplication of amounts otherwise payable hereunder) such additional amount or amounts as will compensate such Bank or its Parent for such reduction. (c) Each Bank will promptly notify the Borrower and the Administrative Agent of any event of which it has knowledge, occurring after the Effective Date, which will entitle such Bank to compensation pursuant to this Section and will designate a different Applicable Lending Office if such designation will avoid the need for, or reduce the amount of, such compensation and will not, in the reasonable judgment of such Bank, be otherwise disadvantageous to such Bank. A certificate of any Bank claiming compensation under this Section, setting forth the additional amount or amounts to be paid to it hereunder and setting forth in reasonable detail the basis for such compensation shall be conclusive in the absence of manifest error, and the amount set forth therein shall be payable by the Borrower within five days after receipt of such certificate. In determining such amount, such Bank may use any reasonable averaging and attribution methods. SECTION 8.04. Substitute Loans. If (i) the obligation of any Bank to make Euro-Dollar Loans has been suspended pursuant to Section 8.01 or 8.02 or (ii) any Bank has demanded compensation under Section 8.03(a) and the Borrower shall, by at least five Euro-Dollar Business Days' prior notice to such Bank through the Administrative Agent, have elected that the provisions of this Section shall apply to such Bank, then, unless and until such Bank notifies the Borrower that the circumstances giving rise to such suspension or demand for compensation no longer apply (which such Bank shall do forthwith): (a) all Loans which would otherwise be made by such Bank as CD Loans or Euro-Dollar Loans, as the case may be, shall be made instead as Base Rate Loans or, if the Borrower shall so elect in its Notice of Borrowing, CD Loans or Euro-Dollar Loans (whichever type is not affected by such circumstances) for an Interest Period coincident with the related Fixed Rate Borrowing, and (b) after each of its CD Loans or Euro-Dollar Loans, as the case may be, has been repaid, all payments of principal which would otherwise be applied to repay such Fixed Rate Loans shall instead be applied to repay its Loans made pursuant to Section 8.02 or clause (a) above. SECTION 8.05. Regulation D Compensation. Each Bank may require the Borrower to pay, contemporaneously with each payment of interest on Euro-Dollar Borrowings, additional interest on the related Euro-Dollar Loan of such Bank at a rate per annum equal to the excess of (i) (A) the applicable Euro-Dollar Rate divided by (B) one minus the Euro-Dollar Reserve Percentage over (ii) the rate specified in clause (i)(A). Any Bank electing to require payment of such additional interest (x) shall so 58 notify the Borrower and the Administrative Agent, in which case such additional interest on the Euro-Dollar Loans of such Bank shall be payable to such Bank at the place indicated in such notice with respect to each Interest Period commencing at least five Euro-Dollar Business Days after the giving of such notice and (y) shall notify the Borrower at least five Euro-Dollar Business Days prior to each date on which interest is payable on the Euro-Dollar Loans of the amount then due it under this Section. SECTION 8.06. Substitution of Bank. If (i) the obligation of any Bank to make Euro-Dollar Loans has been suspended pursuant to Section 8.01 or 8.02 or (ii) any Bank has demanded compensation under Section 8.03 or 8.05, or if any Bank has notified the Borrower that it is not capable of receiving payments without deduction or withholding pursuant to Section 2.18 the Borrower shall have the right, with the assistance of the Administrative Agent and the Co- Agent, to seek a mutually satisfactory substitute bank or banks (which may be one or more of the Banks) to purchase the Notes for cash without recourse to such Bank and assume the Commitment and participation in any Letters of Credit of such Bank. Any such purchase shall be at par, shall be subject to the provisions of Section 2.14, shall be without prejudice to the Borrower's obligations under Section 9.04 and shall release such Bank from all further obligations under this Agreement.

SECTION 9.07. Successors and Assigns. (a) The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns, except that the Borrower may not assign or otherwise transfer any of its rights under this Agreement without the prior written consent of all Banks. (b) Any Bank may at any time grant to one or more banks or other institutions (each a "Participant") participating interests in its Commitment or any or all of its Loans or any or all of its Commitment Percentage of Letter of Credit Outstandings.

(e) If any Reference Bank assigns its Notes to an unaffiliated institution, the Administrative Agent shall, in consultation with the Borrower and with the consent of the Required Banks, appoint another bank to act as a Reference Bank hereunder.

SECTION 9.10. Headings. The Table of Contents and Article and Section headings used herein shall not affect the interpretation of any provision of this Agreement. 63 SECTION 9.11. Sharing of Setoffs. Each Bank agrees that, if it shall, by exercising any right of setoff or counterclaim or otherwise, receive payment of a proportion of the aggregate amount of principal and interest due with respect to any Note held by it or any Letter of Credit Outstandings which is greater than the proportion received by any other Bank in respect of the aggregate amount of principal and interest due with respect to any Note held by such other Bank or any Letter of Credit Outstandings (other than disproportionate payments to any Bank provided for by this Agreement), the Bank receiving such proportionately greater payment shall purchase such participation in the Notes held by, or the rights in respect of Letter of Credit Outstandings of, the other Banks, and such other adjustments shall be made, as may be required so that all such payments of principal and interest with respect to the Notes and Letter of Credit Outstandings held by the Banks shall be shared by the Banks pro rata; provided, however, that nothing in this Section shall impair the right of any Bank to exercise any right of setoff or counterclaim it may have and to apply the amount recovered thereby to the payment of indebtedness of the Borrower other than its indebtedness under the Notes, or in respect of Letter of Credit Outstandings. If under any applicable bankruptcy, insolvency or other similar law, any Bank receives a secured claim in lieu of a setoff to which this Section applies, such Bank shall, to the extent practicable, exercise its rights in respect of such secured claim in a manner consistent with the rights of the Banks entitled under this Section to share in the benefits of any recovery on such secured claim. SECTION 9.12. Collateral. Each of the Banks represents to the Agents and each of the other Banks that it in good faith is not relying upon any "margin stock" (as defined in Regulation U) as collateral in the extension or maintenance of the credit provided for in this Agreement.

THE BORROWER AGREES THAT A FINAL, NONAPPEALABLE JUDGMENT IN ANY SUCH SUIT, ACTION OR PROCEEDING BROUGHT IN ANY SUCH A COURT SHALL BE CONCLUSIVE AND BINDING UPON THE BORROWER AND MAY BE ENFORCED IN ANY FEDERAL OF STATE COURT SITTING IN THE STATE OF TEXAS (OR ANY OTHER COURTS TO THE JURISDICTION OF WHICH THE BORROWER IS OR MAY BE SUBJECT) BY A SUIT UPON SUCH JUDGMENT; PROVIDED, HOWEVER, THAT SERVICE OF PROCESS IS EFFECTED 64 UPON THE BORROWER IN ONE OF THE MANNERS SPECIFIED IN SUBSECTION (b) OF THIS SECTION OR AS OTHERWISE PERMITTED BY LAW.
