ARTICLE II THE CREDIT SECTION 2.1. Commitments. (a) Each Bank severally agrees, subject to Sections 2.1(c), 7.1 and 7.2 and the other terms and conditions set forth in this Agreement, to lend to Borrower from time to time prior to the Revolver Conversion Date, amounts not to exceed in the aggregate at any one time outstanding, the amount of such Bank's Commitment reduced by an amount equal to such Bank's Letter of Credit Exposure. Each Borrowing shall be in an aggregate principal amount of $200,000 or any larger integral multiple of $500,000 (except that any Base Rate Borrowing may be in an amount equal to the Availability at such time), and (ii) shall be made from 22 29 such Banks ratably in accordance with their respective Commitment Percentages. Subject to the foregoing limitations and the other provisions of this Agreement, prior to the Revolver Conversion Date, Borrower may borrow under this Section 2.1(a), repay amounts borrowed and request new Borrowings to be made under this Section 2.1(a). (b) Administrative Agent will, from time to time prior to the Revolver Conversion Date, upon request by Borrower, issue Letters of Credit for the account of Borrower, so long as (i) the sum of (A) the total Letter of Credit Exposure then existing, and (B) the amount of the requested Letter of Credit does not exceed twenty percent (20%) of the Borrowing Base, and (ii) Borrower would be entitled to a Borrowing under Sections 2.1(a) and 2.1(c) in the amount of the requested Letter of Credit. Not less than three (3) Domestic Business Days prior to the requested date of issuance of any such Letter of Credit, Borrower shall execute and deliver to Administrative Agent, Administrative Agent's customary letter of credit application. Each Letter of Credit shall be in the minimum amount of $10,000 and shall be in form and substance acceptable to Administrative Agent. No Letter of Credit shall have an expiration date later than thirty (30) days prior to the Revolver Conversion Date. Upon the date of issuance of a Letter of Credit, Administrative Agent shall be deemed to have sold to each other Bank, and each other Bank shall be deemed to have unconditionally and irrevocably purchased from Administrative Agent, a non-recourse participation in the related Letter of Credit and Letter of Credit Exposure equal to such Bank's Commitment Percentage of such Letter of Credit and Letter of Credit Exposure. Upon request of any Bank, but not less often than quarterly, Administrative Agent shall provide notice to each Bank by telephone, teletransmission or telex setting forth each Letter of Credit issued and outstanding pursuant to the terms hereof and specifying the beneficiary and expiration date of each such Letter of Credit, each Bank's percentage of each such Letter of Credit and the actual dollar amount of each Bank's participation held by Administrative Agent for such Bank's account and risk. At the time of issuance of each Letter of Credit, Borrower shall pay to Administrative Agent in respect of such Letter of Credit (a) the applicable Letter of Credit Fee, and (b) the applicable Letter of Credit Fronting Fee. Administrative Agent shall distribute the Letter of Credit Fee payable upon the issuance of each Letter of Credit to Banks in accordance with their respective Commitment Percentages, and Administrative Agent shall retain the Letter of Credit Fronting Fee for its own account. Any amendment, modification, renewal or extension of any Letter of Credit shall be deemed to be the issuance of a new Letter of Credit for purposes of this Section 2.1(b). Immediately upon the occurrence of an Event of Default, Borrower shall deposit with Administrative Agent cash in such amounts as Administrative Agent may request, up to a maximum amount equal to the aggregate existing Letter of Credit Exposure of all Banks. Any amounts so deposited shall be held by Administrative Agent for the ratable benefit of all Banks as security for the outstanding Letter of Credit Exposure and the other Obligations, and Borrower will, in connection therewith, execute and deliver such security agreements in form and substance satisfactory to Administrative Agent which it may, in its discretion, require. As drafts or demands for payment are presented under any Letter of Credit, Administrative Agent shall apply such cash to satisfy such drafts or demands. When all Letters of Credit have expired and the Obligations have been repaid in full (and no Bank has any obligation to lend or issue Letters of Credit hereunder) or such Event of Default has been cured to the satisfaction of Required Banks, Administrative Agent shall release to Borrower any remaining cash deposited under this Section 2.1(b). Whenever Borrower is required to make deposits under this Section 2.1(b) and fails to do so on the day such 23 30 deposit is due, Administrative Agent or any Bank may, without notice to Borrower, make such deposit (whether by application of proceeds of any collateral for the Obligations, by transfers from other accounts maintained with any Bank or otherwise) using any funds then available to any Bank of any Credit Party or any other party liable for repayment of the Obligations. Notwithstanding anything to the contrary contained herein, Borrower hereby agrees to reimburse Administrative Agent immediately upon demand by Administrative Agent, and in immediately available funds, for any payment or disbursement made by Administrative Agent under any Letter of Credit issued by it. Payment shall be made by Borrower with interest on the amount so paid or disbursed by Administrative Agent from and including the date payment is made under any Letter of Credit to and including the date of payment, at the Default Rate. The obligations of Borrower under this Section 2.1(b) will continue until all Letters of Credit have expired and all reimbursement obligations with respect thereto have been paid in full by Borrower and until all other Obligations shall have been paid in full. The reimbursement obligations of Borrower under this Section 2.1(b) shall be absolute, unconditional and irrevocable, and shall be performed strictly in accordance with the terms of the Loan Documents (including any letter of credit application or agreement executed pursuant to this Section 2.1(b)) under all circumstances whatsoever and Borrower hereby waives any defense to the payment of such reimbursement obligations based on any circumstance whatsoever, including without limitation, in any case, the following circumstances: (i) any lack of validity or enforceability of any Letter of Credit; (ii) the existence of any claim, set-off, counterclaim, defense or other Rights which Borrower or any other Person may have at any time against any beneficiary of any Letter of Credit, Administrative Agent, any Bank or any other Person, whether in connection with any Letter of Credit or any unrelated transaction; (iii) any statement, draft or other documentation presented under any 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 whatsoever; (iv) payment by Administrative Agent under any Letter of Credit against presentation of a draft or other document that does not comply with the terms of such Letter of Credit; or (v) any other circumstance whatsoever, whether or not similar to any of the foregoing. As among Borrower, on the one hand, and Administrative Agent and each Bank, on the other hand, Borrower assumes all risks of the acts and omissions of, or misuse of any Letter of Credit by, the beneficiary of such Letters of Credit. In furtherance and not in limitation of the foregoing, neither Administrative Agent nor any Bank shall be responsible for: (i) the form, validity, sufficiency, accuracy, genuineness or legal effect of any document submitted by any Person in connection with the application for, issuance of, and presentation of drafts with respect to, any Letter of Credit, even if it should prove to be in any or all respects invalid, insufficient, inaccurate, fraudulent or forged; (ii) the validity or sufficiency of any instrument transferring or assigning or purporting to transfer or assign any Letter of Credit or the Rights or benefits thereunder or proceeds thereof, in whole or in part, which may prove to be invalid or ineffective for any reason; 24 31 (iii) the failure of the beneficiary of any Letter of Credit to comply duly with conditions required in order to draw upon any such Letter of Credit; (iv) errors, omissions, interruptions or delays in transmission or delivery of any messages, by mail, cable, telegraph, telex or otherwise, whether or not they be in cipher; (v) errors in interpretation of technical terms; (vi) any loss or delay in the transmission or otherwise of any document required in order to make a drawing under any Letter of Credit or of the proceeds thereof; (vii) the misapplication by the beneficiary of any Letter of Credit of the proceeds of any drawing under any such Letter of Credit; or (viii) any consequences arising from causes beyond the control of Administrative Agent or any Bank. Borrower shall be obligated to reimburse Administrative Agent upon demand for all amounts paid under any Letter of Credit as set forth in the immediately preceding paragraph hereof; provided however if Borrower for any reason fails to reimburse Administrative Agent in full upon demand, Banks shall reimburse Administrative Agent in accordance with each Banks' Commitment Percentage for amounts due and unpaid from Borrower as set forth hereinbelow; provided however that no such reimbursement made by Banks shall discharge Borrower's obligations to reimburse Administrative Agent. All reimbursement amounts payable by any Bank under this Section 2.1(b) shall include interest thereon at the Federal Funds Rate from the date of the payment of such amounts by Administrative Agent to the date of reimbursement by such Bank. No Bank shall be liable for the performance or nonperformance of the obligations of any other Bank under this Section 2.1(b). The reimbursement obligations of Banks under this Section 2.1(b) shall continue after the Termination Date and shall survive termination of this Agreement and the other Loan Documents. (c) No Bank will be obligated to lend to Borrower hereunder or incur Letter of Credit Exposure, and Borrower shall not be entitled to borrow hereunder or obtain Letters of Credit hereunder in an amount which would cause the Outstanding Credit to exceed the Borrowing Base then in effect. No Bank shall be obligated to fund Borrowings hereunder and Borrower shall not be entitled to Borrowings hereunder during the existence of a Borrowing Base Deficiency. (d) In order to request any Borrowing under this Section 2.1, Borrower shall hand deliver, telex or telecopy to Administrative Agent a duly completed Request for Borrowing (herein so called) prior to 11:00 a.m. (New York, New York time), (i) at least one (1) Domestic Business Day before the specified Borrowing Date of a proposed Base Rate Borrowing, and (ii) at least three (3) Eurodollar Business Days before the specified Borrowing Date of a proposed Eurodollar Borrowing. Each such Request for Borrowing shall be substantially in the form of Exhibit F hereto, and shall specify: 25 32 (i) the Borrowing Date of such Borrowing, which shall be a Domestic Business Day in the case of a Base Rate Borrowing or a Eurodollar Business Day in the case of a Eurodollar Borrowing; (ii) the aggregate amount of such Borrowing; (iii) whether such Borrowing is to be a Base Rate Borrowing or a Eurodollar Borrowing; and (iv) in the case of a Eurodollar Borrowing, the duration of the Interest Period applicable thereto, subject to the provisions of the definition of Interest Period. Upon receipt of a Request for Borrowing, Administrative Agent shall promptly notify each Bank of the contents thereof and the amount of the Borrowing to be loaned by such Bank pursuant thereto, and such Request for Borrowing shall not thereafter be revocable by Borrower. Not later than 11:00 a.m. (New York, New York time) on the date of each Borrowing, each Bank shall make available its Commitment Percentage of such Borrowing, in Federal or other funds immediately available in New York, New York to Administrative Agent at its address set forth on Schedule 1.1 hereto. Notwithstanding the foregoing, if Borrower delivers to Administrative Agent a Request for Borrowing prior to 10:00 a.m. (New York, New York time) on a Domestic Business Day requesting a Base Rate Borrowing on such day, each Bank shall use its best efforts to make available to Administrative Agent its Commitment Percentage of such Borrowing by 1:00 p.m. (New York, New York time) on the same day. Unless Administrative Agent determines that any applicable condition specified in Section 7.2 has not been satisfied, Administrative Agent will make the funds so received from Banks available to Borrower at Administrative Agent's aforesaid address. (e) In order to request any Letter of Credit hereunder, Borrower shall hand deliver, telex or telecopy to Administrative Agent a duly completed Request for Letter of Credit (herein so called) prior to 11:00 a.m. (New York, New York time) at least three (3) Domestic Business Days before the date specified for issuance of such Letter of Credit. Each Request for Letter of Credit shall be substantially in the form of Exhibit G hereto, shall be accompanied by Administrative Agent's duly completed and executed letter of credit application and agreement and shall specify: (i) the requested date for issuance of such Letter of Credit; (ii) the terms of such requested Letter of Credit, including the name and address of the beneficiary, the stated amount, the expiration date and the conditions under which drafts under such Letter of Credit are to be available; and (iii) the purpose of such Letter of Credit. Upon receipt of a Request for Letter of Credit, Administrative Agent shall promptly notify each Bank of the contents thereof, including the amount of the requested Letter of Credit, and such Request for Letter of Credit shall not thereafter be revocable by Borrower. Not later than 11:00 a.m. (New York, New York time) on the date each Letter of Credit is requested, unless Administrative Agent 26 33 determines that any applicable condition precedent set forth in Section 7.2 hereof has not been satisfied, Administrative Agent will issue and deliver such Letter of Credit pursuant to the instructions of Borrower. SECTION 2.2. Notes. Each Bank's Commitment Percentage of the Loan shall be evidenced by a single Note payable to the order of such Bank in an amount equal to such Bank's Commitment. SECTION 2.3. Interest Rates; Payments. (a) The principal amount of the Base Rate Loan shall bear interest at a rate per annum equal to (i) prior to the Revolver Conversion Date, the sum of the Applicable Revolver Margin plus the Base Rate in effect from day to day, and (ii) from and after the Revolver Conversion Date, the sum of the Applicable Term Margin plus the Base Rate in effect from day to day; provided that in no event shall the rate charged hereunder or under the Notes exceed the Maximum Lawful Rate. Interest on the Base Rate Loan shall be payable as it accrues on the last day of each Fiscal Quarter, on the Revolver Conversion Date, and on the Termination Date. (b) The principal amount of each Eurodollar Loan shall bear interest for the Interest Period applicable thereto at a rate per annum equal to (i) prior to the Revolver Conversion Date, the sum of the Applicable Revolver Margin plus the applicable Adjusted Eurodollar Rate, and (ii) from and after the Revolver Conversion Date, the sum of the Applicable Term Margin plus the applicable Adjusted Eurodollar Rate; provided that in no event shall the rate charged hereunder or under the Notes exceed the Maximum Lawful Rate. Interest on any Eurodollar Loan with an interest period of three (3) months or less shall be payable on the last day of the Interest Period applicable thereto. Interest on any Eurodollar Loan with an Interest Period greater than three (3) months shall be payable as it accrues at three month intervals commencing with the expiration of three months following the commencement of such Interest Period. (c) So long as no Default or Event of Default shall be continuing, subject to the provisions of this Section 2.3, Borrower shall have the option of having all or any portion of the principal outstanding under the Loan be a Base Rate Loan or one (1) or more Eurodollar Loans, which shall bear interest at rates determined by reference to the Base Rate and the Adjusted Eurodollar Rate, respectively; provided that each Eurodollar Loan shall be in a minimum amount of $200,000 and shall be in an amount which is an integral multiple of $50,000. Prior to the termination of each Interest Period with respect to each Eurodollar Loan, Borrower shall give written notice (a "Notice of Continuation or Conversion") in the form of Exhibit H attached hereto to Administrative Agent of the Type of Loan which shall be applicable to the principal of such Eurodollar Loan upon the expiration of such Interest Period. Such Notice of Continuation or Conversion shall be given to Administrative Agent at least one (1) Domestic Business Day, in the case of a Base Rate Loan selection, and three (3) Eurodollar Business Days, in the case of a Eurodollar Loan selection, prior to the termination of the Interest Period then expiring. If Borrower shall specify a Eurodollar Loan, such Notice of Continuation or Conversion shall also specify the length of the succeeding Interest Period (subject to the definition of such term) selected by Borrower. Each Notice of Continuation or Conversion shall be irrevocable and effective upon notification thereof to Administrative Agent. If the required Notice of Continuation or Conversion shall not have been timely received by Administrative Agent, Borrower shall be deemed to have elected that the 27 34 principal of the Eurodollar Loan subject to the Interest Period then expiring be a part of the Base Rate Loan upon the expiration of such Interest Period and Borrower will be deemed to have given Administrative Agent notice of such election. Subject to the limitations set forth in this Section 2.3(c) on the amount and number of Eurodollar Loans, Borrower shall have the right to convert (a "Conversion") all or any part of the Base Rate Loan to a Eurodollar Loan by giving Administrative Agent a Notice of Continuation or Conversion of such election at least three (3) Eurodollar Business Days prior to the date on which Borrower elects to make such conversion (a "Conversion Date"). The Conversion Date selected by Borrower shall be a Eurodollar Business Day. Notwithstanding anything in this Section 2.3 to the contrary, no portion of the principal of the Base Rate Loan may be Converted to a Eurodollar Loan and no Eurodollar Loan may be Continued as such when any Default or Event of Default has occurred and is continuing, but each such Eurodollar Loan shall be automatically Converted to the Base Rate Loan on the last day of each applicable Interest Period. Borrower shall not be permitted to have more than three (3) Eurodollar Loans in effect at any time. (d) Notwithstanding anything to the contrary set forth in Section 2.3(a) or (b) above, all overdue principal of and, to the extent permitted by Law, overdue interest, shall bear interest from the date due, payable on demand, for each day until paid at the Default Rate. (e) Administrative Agent shall determine each interest rate applicable to the Loan in accordance with the terms hereof. Administrative Agent shall promptly notify Borrower and Banks by telex, teletransmission or cable of each rate of interest so determined, and its determination thereof shall be conclusive in the absence of manifest error. (f) Notwithstanding the foregoing, if at any time the rate of interest calculated with reference to the Base Rate or the Eurodollar Rate hereunder (the "contract rate") is limited to the Maximum Lawful Rate, any subsequent reductions in the contract rate shall not reduce the rate of interest on the Loan below the Maximum Lawful Rate until the total amount of interest accrued equals the amount of interest which would have accrued if the contract rate had at all times been in effect. In the event that at maturity (stated or by acceleration), or at final payment of any Note, the total amount of interest paid or accrued on such Note is less than the amount of interest which would have accrued if the contract rate had at all times been in effect with respect thereto, then at such time, to the extent permitted by Law, Borrower shall pay to the holder of such Note an amount equal to the difference between (i) the lesser of (a) the amount of interest which would have accrued if the contract rate had at all times been in effect, and (b) the amount of interest which would have accrued if the Maximum Lawful Rate had at all times been in effect, and (ii) the amount of interest actually paid on such Note. (g) Interest payable hereunder on each Eurodollar Loan shall be computed based on the number of actual days elapsed assuming that each calendar year consisted of 360 days. Interest payable hereunder on the Base Rate Loan shall be computed based on the actual number of days elapsed assuming that each calendar year consisted of 365 days. SECTION 2.4. Borrowing Base Deficiency. If, at any time, a Borrowing Base Deficiency shall occur, then, Borrower shall (i) within ninety (90) days after the date such Borrowing Base Deficiency first occurs, either (A) provide additional collateral acceptable to Agent and 28 35 Required Banks as security for the Obligations, with a value as determined by Required Banks in their sole discretion, at least equal to the amount of such Borrowing Base Deficiency, or (B) prepay, without premium or penalty (except as provided in Section 4.5), the Loan, in an amount to at least equal to the amount of such Borrowing Base Deficiency. SECTION 2.5. Mandatory Repayments. If, on any date, the aggregate outstanding principal balance of the Loan on such date shall exceed the Total Commitment, then, Borrower shall immediately repay, without premium or penalty, the principal of the Loan in an amount equal to such excess, along with accrued unpaid interest on the amount so repaid to the date of such repayment. On each Quarterly Date after the Revolver Conversion Date (commencing on December 31, 2000), Borrower shall make a mandatory prepayment of the principal of the Loan then outstanding in an amount equal to one-twelfth (1/12th) of the aggregate principal balance of the Loan outstanding on the Revolver Conversion Date. SECTION 2.6. Voluntary Prepayments. Borrower may, subject to Section 4.5 and the other provisions of this Agreement, upon (A) one (1) Domestic Business Day's advance notice to Administrative Agent with respect to Base Rate Borrowings, and (B) five (5) Domestic Business Days advance notice to Administrative Agent with respect to Eurodollar Borrowings, prepay the principal of the Loan in whole or in part. Any partial prepayment shall be in a minimum amount of $200,000 and shall be in an integral multiple of $50,000, and (i) to the extent made after the Revolver Conversion Date (a) may not be reborrowed hereunder, and (b) shall be applied to the mandatory prepayments required by Section 2.5 hereof in the inverse order of maturity, and (ii) to the extent made with respect to any Eurodollar Loan, may be made only on the last day of the Interest Period applicable thereto. SECTION 2.7. Voluntary Reduction of Commitments. Borrower may, by notice to Administrative Agent five (5) Domestic Business Days prior to the effective date of any such reduction, reduce the Total Commitment (and thereby reduce the Commitment of each Bank ratably) in amounts not less than $5,000,000 and in an amount which is an integral multiple of $1,000,000. On the effective date of any such reduction, Borrower shall, to the extent required as a result of such reduction, make a principal payment on the Loan in an amount sufficient to cause the Outstanding Credit to be equal to or less than the Total Commitment as thereby reduced. Notwithstanding the foregoing, Borrower shall not be permitted to voluntarily reduce the Total Commitment to an amount less than the aggregate Letter of Credit Exposure of all Banks. SECTION 2.8. Mandatory Reduction of Commitments. The Total Commitment shall reduce (and the Commitments of each Bank shall reduce ratably) on the Revolver Conversion Date to an amount equal to the principal balance of the Loan outstanding on the Revolver Conversion Date. The Total Commitment shall reduce after the Revolver Conversion Date (and the Commitments of each Bank shall reduce ratably) (a) on each Quarterly Date in an amount equal to the mandatory prepayment required to be made on such date pursuant to Section 2.5, (b) on the date of each prepayment made pursuant to Section 2.4 by the amount of such prepayment, (c) on the date of each voluntary prepayment made pursuant to Section 2.6 by the amount of such voluntary prepayment, and (d) on the date of each voluntary prepayment made pursuant to Section 2.7 by the amount of such voluntary prepayment. 29 36 SECTION 2.9. Termination of Commitments; Final Maturity of Loan. The Total Commitment (and the Commitment of each Bank) shall terminate, and the entire outstanding principal balance of the Loan, all interest accrued thereon, all accrued but unpaid fees hereunder and all other outstanding Obligations shall be due and payable in full on the Termination Date. SECTION 2.10. Unused Commitment Fee. On the Revolver Conversion Date, on each Quarterly Date prior to the Revolver Conversion Date, and, in the event the Commitments are terminated in their entirety prior to the Revolver Conversion Date, on the date of such termination, Borrower shall pay to Administrative Agent, for the ratable benefit of each Bank based on each Bank's Commitment Percentage, a commitment fee equal to the Commitment Fee Percentage in effect from day to day (applied on a per annum basis and computed on the basis of actual days elapsed and as if each calendar year consisted of 365 days) of the average daily Availability for the Fiscal Quarter (or portion thereof) ending on the date such payment is due. SECTION 2.11. Borrowing Base Increase Fee. On the date of any increase in the Borrowing Base which results in an increase in the Borrowing Base beyond the existing Apex Borrowing Base, Borrower shall pay to Administrative Agent for the ratable benefit of each Bank, a borrowing base increase fee equal to one-half of one percent (.50%) on the difference between (i) the existing Apex Borrowing Base, and (ii) the Borrowing Base on the day of such increase of the Borrowing Base after giving effect to such increase. SECTION 2.12. Agency and other Fees. Borrower shall pay to Administrative Agent and its Affiliates such other fees and amounts as Borrower shall be required to pay to Administrative Agent and its Affiliates from time to time pursuant to any separate agreement between Borrower and Administrative Agent or such Affiliates. Such fees and other amounts shall be retained by Administrative Agent and its Affiliates, and no Bank (other than Administrative Agent) shall have any interest therein. ARTICLE III GENERAL PROVISIONS SECTION 3.1. Delivery and Endorsement of Notes. Simultaneously with the execution of this Agreement, Administrative Agent shall deliver to each Bank the Notes payable to such Bank. Each Bank may endorse (and prior to any transfer of its Notes shall endorse) on the schedules attached and forming a part thereof appropriate notations to evidence the date and amount of its Commitment Percentage of each Borrowing, the Interest Period applicable thereto, and the date and amount of each payment of principal made by Borrower with respect thereto; provided that the failure by any Bank to so endorse its Notes shall not affect the liability of Borrower for the repayment of all amounts outstanding under such Notes together with interest thereon. Each Bank is hereby irrevocably authorized by Borrower to endorse its Notes and to attach to and make a part of any Notes a continuation of any such schedule as required. SECTION 3.2. General Provisions as to Payments. (a) Borrower shall make each payment of principal of, and interest on, the Loan and all fees payable hereunder shall be paid not 30 37 later than 11:00 a.m. (New York, New York time) on the date when due, in Federal or other funds immediately available in New York, New York, to Administrative Agent at its address set forth on Schedule 1.1 hereto. Administrative Agent will promptly (and if such payment is received by Administrative Agent by 10:00 a.m. (New York, New York time), and otherwise if reasonably possible, on the same Domestic Business Day) distribute to each Bank its Commitment Percentage of each such payment received by Administrative Agent for the account of Banks. Whenever any payment of principal of, or interest on, any portion of the Base Rate Loan 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 (subject to the definition of Interest Period). Whenever any payment of principal of, or interest on, any portion of any Eurodollar Loan shall be due on a day which is not a Eurodollar Business Day, the date for payment thereof shall be extended to the next succeeding Eurodollar Business Day (subject to the definition of Interest Period). 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. Borrower hereby authorizes Administrative Agent to charge from time to time against Borrower's accounts with Administrative Agent any amount then due. (b) Prior to the occurrence of an Event of Default, all principal payments received by Banks with respect to the Loan shall be applied first to Eurodollar Loans outstanding with Interest Periods ending on the date of such payment, then to the Base Rate Loan, and then to Eurodollar Loans next maturing until such principal payment is fully applied. (c) After the occurrence of an Event of Default, all amounts collected or received by Administrative Agent or any Bank shall be applied first to the payment of all proper costs incurred by Administrative Agent in connection with the collection thereof (including reasonable expenses and disbursements of Administrative Agent), second to the payment of all proper costs incurred by Banks in connection with the collection thereof (including reasonable expenses and disbursements of Banks), third to the reimbursement of any advances made by Banks to effect performance of any unperformed covenants of any Credit Party under any of the Loan Documents, fourth to the payment of any unpaid fees required pursuant to Section 2.13, fifth to the payment of any unpaid fees required pursuant to Sections 2.1(b), 2.10, 2.11, and 2.12 sixth to payment to each Bank of its Commitment Percentage of the outstanding principal of the Loan and accrued but unpaid interest thereon, and seventh to establish the deposits required pursuant to Section 2.1(b).

ARTICLE IV CHANGE IN CIRCUMSTANCES SECTION 4.1. Increased Cost and Reduced Return. (a) If, after the date hereof, the adoption of any applicable Law, rule, or regulation, or any change in any applicable Law, rule, or regulation, 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 31 38 Applicable Lending Office) with any request or directive (whether or not having the force of law) of any such Governmental Authority, central bank, or comparable agency: (i) shall subject such Bank (or its Applicable Lending Office) to any Tax, duty, or other charge with respect to any Eurodollar Loans, its Note, or its obligation to make Eurodollar Loans, or change the basis of taxation of any amounts payable to such Bank (or its Applicable Lending Office) under this Agreement or its Note in respect of any Eurodollar Loans (other than Taxes imposed on the overall net income of such Bank by the jurisdiction in which such Bank has its principal office or such Applicable Lending Office); (ii) shall impose, modify, or deem applicable any reserve, special deposit, assessment, compulsory loan, or similar requirement (other than the Reserve Requirement utilized in the determination of the Adjusted Eurodollar Rate) relating to any extensions of credit or other assets of, or any deposits with or other liabilities or commitments of, such Bank (or its Applicable Lending Office), including the Commitment of such Bank hereunder; or (iii) shall impose on such Bank (or its Applicable Lending Office) or on the London interbank market any other condition affecting this Agreement or its Note or any of such extensions of credit or liabilities or commitments; and (iv) the result of any of the foregoing is to increase the cost to such Bank (or its Applicable Lending Office) of making, Converting into, Continuing, or maintaining any Eurodollar Loans or to reduce any sum received or receivable by such Bank (or its Applicable Lending Office) under this Agreement or its Note with respect to any Eurodollar Loans, then Borrower shall pay to such Bank on demand such amount or amounts as will compensate such Bank for such increased cost or reduction. If any Bank requests compensation by Borrower under this Section 4.1(a), Borrower may, by notice to such Bank (with a copy to Administrative Agent), suspend the obligation of such Bank to make or Continue Eurodollar Loans or to Convert all or part of the Base Rate Loan owing to such Bank into Eurodollar Loans, until the event or condition giving rise to such request ceases to be in effect (in which case the provisions of Section 4.4 shall be applicable); provided that such suspension shall not affect the right of such Bank to receive the compensation so requested. (b) If, after the date hereof, any Bank shall have determined that the adoption of any applicable Law, rule, or regulation regarding capital adequacy or any change therein or in the interpretation or administration thereof by any Governmental Authority, central bank, or comparable agency charged with the interpretation or administration thereof, or any request or directive regarding capital adequacy (whether or not having the force of law) of any such Governmental Authority, central bank, or comparable agency, has or would have the effect of reducing the rate of return on the capital of such Bank or any corporation controlling such Bank as a consequence of such Bank's obligations hereunder to a level below that which such Bank or such corporation could have achieved but for such adoption, change, request, or directive (taking into consideration its policies with respect to capital adequacy), then from time to time upon demand Borrower shall pay to such Bank such additional amount or amounts as will compensate such Bank for such reduction. 32 39 (c) Each Bank shall promptly notify Borrower and Administrative Agent of any event of which it has knowledge, occurring after the date hereof, which will entitle such Bank to compensation pursuant to this Section 4.1 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 judgment of such Bank, be otherwise disadvantageous to it. Any Bank claiming compensation under this Section 4.1 shall furnish to Borrower and Administrative Agent a statement setting forth the additional amount or amounts to be paid to it hereunder which shall be conclusive in the absence of manifest error. In determining such amount, such Bank may use any reasonable averaging and attribution methods. SECTION 4.2. Limitation on Eurodollar Loans. If on or prior to the first day of any Interest Period for any Eurodollar Loan: (a) Administrative Agent determines (which determination shall be conclusive) that by reason of circumstances affecting the relevant market, adequate and reasonable means do not exist for ascertaining the Eurodollar Rate for such Interest Period; or (b) Required Banks determine (which determination shall be conclusive) and notify Administrative Agent that the Adjusted Eurodollar Rate will not adequately and fairly reflect the cost to Banks of funding Eurodollar Loans for such Interest Period; then Administrative Agent shall give Borrower prompt notice thereof and the relevant amounts or periods, and so long as such condition remains in effect, Banks shall be under no obligation to make additional Eurodollar Loans, Continue Eurodollar Loans, or to Convert all or any part of the Base Rate Loan into Eurodollar Loans and Borrower shall, on the last day(s) of the then current Interest Period(s) for the outstanding Eurodollar Loans, either prepay such Eurodollar Loans or Convert such Eurodollar Loans into the Base Rate Loan in accordance with the terms of this Agreement. SECTION 4.3. Illegality. Notwithstanding any other provision of this Agreement, in the event that it becomes unlawful for any Bank or its Applicable Lending Office to make, maintain, or fund Eurodollar Loans hereunder, then such Bank shall promptly notify Borrower thereof and such Bank's obligation to make or Continue Eurodollar Loans and to Convert all or any part of the Base Rate Loan into Eurodollar Loans shall be suspended until such time as such Bank may again make, maintain, and fund Eurodollar Loans (in which case the provisions of Section 4.4 shall be applicable). SECTION 4.4. Treatment of Affected Loans. If the obligation of any Bank to make particular Eurodollar Loans or to Continue Eurodollar Loans, or to Convert all or any part of the Base Rate Loan into Eurodollar Loans shall be suspended pursuant to Section 4.1 or 4.3 hereof, such Bank's Eurodollar Loans shall be automatically Converted into the Base Rate Loan on the last day(s) of the then current Interest Period(s) for Eurodollar Loans (or, in the case of a Conversion required by Section 4.3 hereof, on such earlier date as such Bank may specify to Borrower with a copy to Administrative Agent) and, unless and until such Bank gives notice as provided below that the circumstances specified in Section 4.1 or 4.3 hereof that gave rise to such Conversion no longer exist: 33 40 (a) to the extent that such Bank's Eurodollar Loans have been so Converted, all payments and prepayments of principal that would otherwise be applied to such Bank's Eurodollar Loans shall be applied instead to the Base Rate Loan; and (b) all Loans that would otherwise be made or Continued by such Bank as Eurodollar Loans shall be made or Continued instead as part of the Base Rate Loan, and all or any part of the Base Rate Loan that would otherwise be Converted into Eurodollar Loans shall remain as part of the Base Rate Loan. If such Bank gives notice to Borrower (with a copy to Administrative Agent) that the circumstances specified in Section 4.1 or 4.3 hereof that gave rise to the Conversion of such Bank's Eurodollar Loans pursuant to this Section 4.4 no longer exist (which such Bank agrees to do promptly upon such circumstances ceasing to exist) at a time when Eurodollar Loans made by other Banks are outstanding, such Bank's portion of the Base Rate Loan shall be automatically Converted, on the first day(s) of the next succeeding Interest Period(s) for such outstanding Eurodollar Loans, to the extent necessary so that, after giving effect thereto, all Loans held by Banks holding Eurodollar Loans are held pro rata (as to principal amounts, and Interest Periods) in accordance with their respective Commitments. SECTION 4.5. Compensation. Upon the request of any Bank, Borrower shall pay to such Bank such amount or amounts as shall be sufficient (in the reasonable opinion of such Bank) to compensate it for any loss, cost, or expense (including loss of anticipated profits) incurred by it as a result of: (a) any payment, prepayment, or Conversion of a Eurodollar Loan for any reason (including, without limitation, the acceleration of the Loan) on a date other than the last day of the Interest Period for such Loan; or (b) any failure by Borrower for any reason (including, without limitation, the failure of any condition precedent specified in Article VII to be satisfied) to borrow, Convert, Continue, or prepay a Eurodollar Loan on the date for such Borrowing, Conversion, Continuation, or prepayment specified in the relevant notice of Borrowing, prepayment, Continuation, or Conversion under this Agreement. SECTION 4.6. Taxes. (a) Any and all payments by Borrower to or for the account of any Bank or Administrative Agent hereunder or under any other Loan Document shall be made free and clear of and without deduction for any and all present or future Taxes, duties, levies, imposts, deductions, charges or withholdings, and all liabilities with respect thereto, excluding, in the case of each Bank and Administrative Agent, Taxes imposed on its income, and franchise Taxes imposed on it, by the jurisdiction under the Laws of which such Bank (or its Applicable Lending Office) or Administrative Agent (as the case may be) is organized or any political subdivision thereof (all such non-excluded Taxes, duties, levies, imposts, deductions, charges, withholdings, and liabilities being hereinafter referred to as "Non-Excluded Taxes"). If Borrower shall be required by Law to deduct any Non-Excluded Taxes from or in respect of any sum payable under this Agreement or any other Loan Document to any Bank or Administrative Agent, (i) the sum payable shall be increased as necessary so that after making all required deductions (including deductions applicable 34 41 to additional sums payable under this Section 4.6) such Bank or Administrative Agent receives an amount equal to the sum it would have received had no such deductions been made, (ii) Borrower shall make such deductions, (iii) Borrower shall pay the full amount deducted to the relevant taxation authority or other authority in accordance with applicable Law, and (iv) Borrower shall furnish to Administrative Agent, at its address referred to in Section 14.1, the original or a certified copy of a receipt evidencing payment thereof. (b) In addition, Borrower agrees to pay any and all present or future stamp or documentary Taxes and any other excise or property Taxes or charges or similar levies which arise from any payment made under this Agreement or any other Loan Document or from the execution or delivery of, or otherwise with respect to, this Agreement or any other Loan Document (hereinafter referred to as "Other Taxes"). (c) Borrower agrees to indemnify each Bank and Administrative Agent for the full amount of Non-Excluded Taxes and Other Taxes (including, without limitation, any Non- Excluded Taxes or Other Taxes imposed or asserted by any jurisdiction on amounts payable under this Section 4.6) paid by such Bank or Administrative Agent (as the case may be) and any liability (including penalties, interest, and expenses) arising therefrom or with respect thereto. (d) Each Bank organized under the Laws of a jurisdiction outside the United States, on or prior to the date of its execution and delivery of this Agreement in the case of each Bank listed on the signature pages hereof and on or prior to the date on which it becomes a Bank in the case of each other Bank, and from time to time thereafter if requested in writing by Borrower or Administrative Agent (but only so long as such Bank remains lawfully able to do so), shall provide Borrower and Administrative Agent with (i) Internal Revenue Service Form 1001 or 4224, as appropriate, or any successor form prescribed by the Internal Revenue Service, certifying that such Bank is entitled to benefits under an income tax treaty to which the United States is a party which reduces the rate of withholding tax on payments of interest or certifying that the income receivable pursuant to this Agreement is effectively connected with the conduct of a trade or business in the United States, (ii) Internal Revenue Service Form W-8 or W-9, as appropriate, or any successor form prescribed by the Internal Revenue Service, and (iii) any other form or certificate required by any taxing authority (including any certificate required by Sections 871(h) and 881(c) of the Code), certifying that such Bank is entitled to an exemption from or a reduced rate of tax on payments pursuant to this Agreement or any of the other Loan Documents. (e) For any period with respect to which a Bank has failed to provide Borrower and Administrative Agent with the appropriate form pursuant to Section 4.6(d) (unless such failure is due to a change in treaty, Law, or regulation occurring subsequent to the date on which a form originally was required to be provided), such Bank shall not be entitled to indemnification under Section 4.6(a) or 4.6(b) with respect to Non-Excluded Taxes imposed by the United States; provided, however, that should a Bank, which is otherwise exempt from or subject to a reduced rate of withholding tax, become subject to Non-Excluded Taxes because of its failure to deliver a form required hereunder, Borrower shall take such steps as such Bank shall reasonably request to assist such Bank to recover such Non-Excluded Taxes. 35 42 (f) If Borrower is required to pay additional amounts to or for the account of any Bank pursuant to this Section 4.6, then such Bank will agree to use reasonable efforts to change the jurisdiction of its Applicable Lending Office so as to eliminate or reduce any such additional payment which may thereafter accrue if such change, in the judgment of such Bank, is not otherwise disadvantageous to such Bank. (g) Within thirty (30) days after the date of any payment of Non-Excluded Taxes, Borrower shall furnish to Administrative Agent the original or a certified copy of a receipt evidencing such payment. (h) Without prejudice to the survival of any other agreement of Borrower hereunder, the agreements and obligations of Borrower contained in this Section 4.6 shall survive the termination of the Commitments and the payment in full of the Notes. SECTION 4.7. Discretion of Banks as to Manner of Funding. Notwithstanding any provisions of this Agreement to the contrary, each Bank shall be entitled to fund and maintain its funding of all or any part of its Commitment in any manner it sees fit, it being understood, however, that for the purposes of this Agreement all determinations hereunder shall be made as if such Bank had actually funded and maintained each Eurodollar Loan during the Interest Period for such Eurodollar Loan through the purchase of deposits having a maturity corresponding to the last day of such Interest Period and bearing an interest rate equal to the Adjusted Eurodollar Rate for such Interest Period. ARTICLE V BORROWING BASE SECTION 5.1. Delivery of Reserve Reports. (a) As soon as available and in any event by February 15 and August 15 of each year commencing February 15, 1999, Borrower shall deliver to each Bank, at Borrower's expense, a Reserve Report prepared as of the immediately preceding December 31 and June 30, respectively. In addition to the foregoing, as soon as available and in any event by May 15 and November 15 of each year commencing May 15, 1999, Borrower shall deliver to each Bank a Reserve Update prepared as of the immediately preceding March 31 and September 30, respectively, which shall set forth the information described in the definition of such term contained in Section 1.1 hereof. As soon as practical after each Bank's receipt of the Reserve Report and the Reserve Update, as applicable, but in no event later than the applicable Redetermination Date, as the case may be, Banks shall redetermine the Maximum Borrowing Base in accordance with Section 5.5 and Administrative Agent shall promptly notify Borrower of the amount of the Maximum Borrowing Base as so determined. (b) In the event that Borrower does not furnish to Banks the Reserve Report and Reserve Update (as applicable) or any other information specified in clause (a) above by the date specified therein, Banks may nonetheless redetermine the Maximum Borrowing Base and redesignate the Maximum Borrowing Base from time to time thereafter at their discretion until Banks receive the relevant Reserve Report or Reserve Update (as applicable) or other information, 36 43 whereupon Banks shall redetermine the Maximum Borrowing Base as otherwise specified in this Article V. (c) Each delivery of a Reserve Report and Reserve Update by Borrower to Banks shall constitute a representation and warranty by Borrower to Administrative Agent and each Bank that, unless otherwise disclosed to Administrative Agent and each Bank in writing on or prior to the date of such delivery, (i) Borrower owns the Mineral Interests described in the Reserve Report (or Reserve Update, as applicable) free and clear of any Liens (except Permitted Encumbrances), and (ii) Mineral Interests representing not less than the Required Reserve Value of the Proven Reserves reflected in such Reserve Report (or Reserve Update, as applicable) constitute Mortgaged Property. SECTION 5.2. Selection of Borrowing Base. Upon notification by Administrative Agent to Borrower of the amount of the Maximum Borrowing Base, Borrower shall notify Administrative Agent and each Bank of the amount of the Borrowing Base requested by Borrower which shall not exceed the amount of the Maximum Borrowing Base. The Borrowing Base selected by Borrower shall be the Borrowing Base which shall remain in effect until the next Redetermination Date, provided that the Borrowing Base may be redetermined between Redetermination Dates in accordance with Section 5.3 hereof. If Borrower fails to notify Administrative Agent and each Bank of the amount of the requested Borrowing Base within ten (10) days after Borrower is notified of the amount of the Maximum Borrowing Base, Borrower will be deemed to have selected the Maximum Borrowing Base. SECTION 5.3. Special Redeterminations of Maximum Borrowing Base. Special Redeterminations of the Maximum Borrowing Base may be requested by Borrower or Required Banks at any time during the term hereof; provided, however, that there shall be no more than an aggregate of two (2) Special Redeterminations in any calendar year. If any Special Redetermination is requested by Borrower, it shall be accompanied by such information regarding Borrower's business (including the Mineral Interests and the Proven Reserves and production relating thereto) as Banks may reasonably request, including without limitation a Reserve Report to be delivered at least fifteen (15) days prior to the requested date of Redetermination. If any Special Redetermination is requested by Required Banks, Borrower shall provide Administrative Agent and each Bank with a Reserve Report as soon as possible following the request; provided, however, such Special Redetermination shall not be counted as a Special Redetermination for purposes of the first sentence of this Section 5.3. The determination whether to increase or decrease the Maximum Borrowing Base shall then be made by all Banks (in the case of an increase) or Required Banks (in the case of a decrease or reaffirmation) in their sole discretion in accordance with the standards set forth in Article V hereof. Promptly following any Special Redetermination pursuant to this Section 5.3, Administrative Agent shall notify Borrower of the amount of the Maximum Borrowing Base as so redetermined. In the event of any Special Redetermination of the Maximum Borrowing Base pursuant to this Section 5.3, Required Banks in the exercise of their discretion may suspend the next regularly Scheduled Redetermination of the Maximum Borrowing Base. SECTION 5.4. Disposition Redetermination. In addition to Scheduled Redeterminations and Special Redeterminations, in the event during any period between Redeterminations of the Borrowing Base, Borrower sells Proven Reserves pursuant to, and in accordance with, Section 10.10 hereof, the Borrowing Base shall be automatically reduced by the 37 44 amounts, and in the manner, provided in such Section 10.10. Promptly following any reduction in the Borrowing Base pursuant to this Section 5.4 and Section 10.10, Administrative Agent shall notify Borrower and each Bank of the amount of the Borrowing Base so reduced, which Borrowing Base shall be effective as of the date specified in such notice, and shall remain in effect for all purposes of this Agreement until the next Redetermination. SECTION 5.5. Standards for Redetermination. Each Redetermination of the Maximum Borrowing Base by Banks made pursuant to this Article V shall be made (i) in the sole discretion of Banks, (ii) generally in accordance with each such Bank's then current practices, customary internal standards and procedures used by each such Bank for its petroleum industry customers for valuing and redetermining the value of oil and gas properties in connection with reserve based on oil and gas loan transactions, (iii) in conjunction with the most recent Reserve Report, Reserve Update or other information received by Administrative Agent and each Bank and deemed reliable by Administrative Agent and each Bank (in their sole discretion) relating to the Proven Reserves of Borrower in the Mineral Interests of Borrower, which secure the Loan (to the extent required by Section 6.1 hereof), and (iv) based upon the estimated value of the Proven Reserves owned by Borrower in the Mineral Interests of Borrower which secure the Loan (to the extent required by Section 6.1 hereof) as determined by Required Banks; provided, however, no Proven Reserves shall be included or considered for inclusion in the Maximum Borrowing Base unless (A) such Proven Reserves are (or will become simultaneously with a Borrowing hereunder) Collateral (to the extent required by Section 6.1 hereof), and (B) Administrative Agent and each Bank shall have received, at Borrower's expense, evidence of title satisfactory in form and substance to Required Banks that Administrative Agent (for the ratable benefit of Banks) has a perfected, first priority Lien (except for Permitted Encumbrances) on such Proven Reserves to the extent required by Section 6.1. At all times after Administrative Agent has given Borrower notification of a Redetermination of the Maximum Borrowing Base under this Article V, the Maximum Borrowing Base shall be equal to the redetermined amount until the Maximum Borrowing Base is subsequently redetermined in accordance with this Article V subject, however, to reduction pursuant to Section 10.10(ii). SECTION 5.6. Voluntary Designation of Borrowing Base. Borrower may from time to time and at any time prior to the Revolver Conversion Date, upon two (2) Domestic Business Days' prior written notice to Administrative Agent and each Bank, decrease the Borrowing Base, by designating a Borrowing Base which is lower than the Borrowing Base then in effect. Any such designation shall be effective as of the date of the notice. SECTION 5.7. Borrowing Base Deficiency. If a Borrowing Base Deficiency exists after giving effect to any Redetermination, Borrower shall be obligated to eliminate such Borrowing Base Deficiency in the manner required by Section 2.4. SECTION 5.8. Initial Borrowing Base. Notwithstanding anything to the contrary contained herein, the Borrowing Base in effect during the period commencing on the Closing Date and ending on the effective date of the first Redetermination after the Closing Date shall be the Initial Borrowing Base. 38 45 ARTICLE VI COLLATERAL AND GUARANTEES SECTION 6.1.

SECTION 8.10. Employee Benefit Plans. (a) Except as set forth on Schedule 8.10, neither Borrower nor any ERISA Affiliate currently sponsors or contributes to, nor has any contract or other obligation to contribute to (nor has Borrower or any ERISA Affiliate in the preceding sixty (60) calendar months sponsored or contributed to, or contracted to or become otherwise obligated to contribute to) any Plan or any Multiemployer Plan. (b) Each Plan is in compliance with all applicable provisions of ERISA, the Code and all other Laws, except for any failures to be in compliance therewith which in the aggregate would not result in a Material Adverse Change. With respect to each Plan (other than a "Multiemployer Plan"), all reports required under ERISA or other applicable Law to be filed with any Governmental Authority, the failure of which to file could reasonably result in a Material Adverse Change, have been timely filed.

Neither Borrower nor any ERISA Affiliate maintains, has established or has ever participated in a multiple employer welfare benefit arrangement as described in section 3(40)(A) of ERISA. (e) Neither Borrower nor any ERISA Affiliate has incurred any material liability to the PBGC in connection with any Plan. The assets of each Plan that is subject to Title IV of ERISA are sufficient to provide the benefits under such Plan, the payment of which the PBGC would guarantee if such Plan were terminated, and such assets are also sufficient to provide all other "benefit liabilities" (as defined in ERISA section 4001(a)(16)) due under the Plan upon termination. No ERISA Event has occurred and is continuing with respect to any Plan. (f) There are no pending, or to the knowledge of Borrower and each ERISA Affiliate, threatened claims, lawsuits or actions (other than routine claims for benefits in the ordinary course) asserted or instituted against, and neither Borrower nor any ERISA Affiliate has knowledge of any threatened litigation or claims against, the assets of any Plan or its related trust or against any fiduciary of a Plan with respect to the operation of such Plan.

Borrower has no Debt other than that listed on Schedule 8.12 attached hereto. SECTION 8.13. Material Contracts. No Credit Party is, nor will the execution, delivery and performance of and compliance with the terms of the Loan Documents cause any Credit Party to be, in default (nor has any potential default occurred) under any Material Contract or any other material agreement, document or instrument other than such defaults or potential defaults which could not, individually or collectively, cause a Material Adverse Effect. SECTION 8.14. No Consents. No order, consent, approval, license, permit, waiver, exemption, authorization of or validation of, or filing, recording or registration with (except as heretofore have been obtained or made), or exemption by, any Person is required to authorize, or is 46 53 required in connection with, the execution, delivery, performance, legality, validity, binding effect, or enforceability of the Loan Documents.

The costs to Borrower and any other Credit Party that have not been incurred as of the date hereof for such reprogramming and testing and for the other reasonably foreseeable consequences to them of any improper functioning of other computer systems and equipment containing embedded microchips due to the occurrence of the year 2000 could not reasonably be expected to result in a Default or Event of Default or to cause a Material Adverse Change.

Appointment, Powers, and Immunities. Each Bank hereby irrevocably appoints and authorizes Administrative Agent to act as its agent under this Agreement and the other Loan Documents with such powers and discretion as are specifically delegated to Administrative Agent by the terms of this Agreement and the other Loan Documents, together with such other powers as are reasonably incidental thereto. Administrative Agent (which term as used in this sentence and in Section 14.5 and the first sentence of Section 14.6 hereof shall include its Affiliates and its own and its Affiliates' officers, directors, employees, and agents) (a) shall not have any duties or responsibilities except those expressly set forth in this Agreement and shall not be a trustee or fiduciary for any Bank; (b) shall not be responsible to Banks for any recital, statement, representation, or warranty (whether written or oral) made in or in connection with any Loan Document or any certificate or other document referred to or provided for in, or received by any of them under, any Loan Document, or for the value, validity, effectiveness, genuineness, enforceability, or sufficiency of any Loan Document, or any other document referred to or provided for therein or for any failure by any Credit Party or any other Person to perform any of its obligations thereunder; (c) shall not be responsible for or have any duty to ascertain, inquire into, or verify the performance or observance of any covenants or agreements by any Credit Party or the satisfaction of any condition or to inspect the property (including the books and records) of any Credit Party or their Affiliates; (d) shall not be required to initiate or conduct any litigation or collection proceedings under any Loan Document; and (e) shall not be responsible for any action taken or omitted to be taken by it under or in connection with any Loan Document, except for its own gross negligence or willful misconduct.

SECTION 14.2. Reliance by Administrative Agent. Administrative Agent shall be entitled to rely upon any certification, notice, instrument, writing, or other communication (including, without limitation, any thereof by telephone or telecopy) believed by it to be genuine and correct and to have been signed, sent or made by or on behalf of the proper Person or Persons, and upon advice and statements of legal counsel (including counsel for Borrower), independent accountants, and other experts selected by Administrative Agent. Administrative Agent may deem and treat the payee of any Note as the holder thereof for all purposes hereof unless and until Administrative Agent receives and accepts an Assignment and Acceptance Agreement executed in accordance with Section 15.10 hereof. As to any matters not expressly provided for by this Agreement, Administrative Agent shall not be required to exercise any discretion or take any action, but shall be required to act or to refrain from acting (and shall be fully protected in so acting or refraining from acting) upon the instructions of Required Banks, and such instructions shall be binding on Banks; provided, however, that Administrative Agent shall not be required to take any action that exposes Administrative Agent to personal liability or that is contrary to any Loan Document or applicable Law unless it shall first be indemnified to its satisfaction by Banks against any and all liability and expense which may be incurred by it by reason of taking any such action. 61 68 SECTION 14.3. Defaults. Administrative Agent shall not be deemed to have knowledge or notice of the occurrence of a Default or Event of Default unless Administrative Agent has received written notice from a Bank or Borrower specifying such Default or Event of Default and stating that such notice is a "Notice of Default". In the event that Administrative Agent receives such a notice of the occurrence of a Default or Event of Default, Administrative Agent shall give prompt notice thereof to Banks. Administrative Agent shall (subject to Section 14.2 hereof) take such action with respect to such Default or Event of Default as shall reasonably be directed by Required Banks; provided that, unless and until Administrative Agent shall have received such directions, Administrative 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 interest of Banks. SECTION 14.4. Rights as Bank. With respect to its Commitment and the Loans made by it, The Chase Manhattan Bank (and any successor acting as Administrative Agent) in its capacity as a Bank hereunder shall have the same Rights and powers hereunder as any other Bank and may exercise the same as though it were not acting as Administrative Agent, and the term "Bank" or "Banks" shall, unless the context otherwise indicates, include Administrative Agent in its individual capacity. The Chase Manhattan Bank (and any successor acting as Administrative Agent) and its Affiliates may (without having to account therefor to any Bank) accept deposits from, lend money to, make investments in, provide services to, and generally engage in any kind of lending, trust, or other business with any Credit Party or any of their Affiliates as if it were not acting as Administrative Agent, and The Chase Manhattan Bank (and any successor acting as Administrative Agent) and its Affiliates may accept fees and other consideration from any Credit Party or any of their Affiliates for services in connection with this Agreement or otherwise without having to account for the same to Banks. SECTION 14.5. Indemnification. Banks agree to indemnify Administrative Agent (to the extent not reimbursed by Borrower or any other Credit Party, but without limiting the obligations of Borrower or any other Credit Party to so reimburse) ratably in accordance with their respective Commitments, for any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses (including attorneys' fees), or disbursements of any kind and nature whatsoever that may be imposed on, incurred by or asserted against Administrative Agent (including by any Bank) in any way relating to or arising out of any Loan Document or the transactions contemplated thereby or any action taken or omitted by Administrative Agent under any Loan Document (INCLUDING ANY OF THE FOREGOING ARISING FROM THE NEGLIGENCE OF ADMINISTRATIVE AGENT); provided that no Bank shall be liable for any of the foregoing to the extent they arise from the gross negligence or willful misconduct of the Person to be indemnified. Without limitation of the foregoing, each Bank agrees to reimburse Administrative Agent promptly upon demand for its ratable share of any costs or expenses payable by Borrower hereunder, to the extent that Administrative Agent is not promptly reimbursed for such costs and expenses by Borrower. The agreements contained in this Section 14.5 shall survive payment and performance in full of the Obligations and all other amounts payable under this Agreement. SECTION 14.6. Non-Reliance on Administrative Agent and Other Banks. Each Bank agrees that it has, independently and without reliance on Administrative Agent or any other Bank, and based on such documents and information as it has deemed appropriate, made its own credit 62 69 analysis of each Credit Party and has made its own decision to enter into this Agreement and that it will, independently and without reliance upon Administrative Agent or any other Bank, and based on such documents and information as it shall deem appropriate at the time, continue to make its own analysis and decisions in taking or not taking action under the Loan Documents. Except for notices, reports, and other documents and information expressly required to be furnished to Banks by Administrative Agent hereunder, Administrative Agent shall not have any duty or responsibility to provide any Bank with any credit or other information concerning the affairs, financial condition, or business of any Credit Party or any of their Affiliates that may come into the possession of Administrative Agent or any of its Affiliates. SECTION 14.7. Resignation of Administrative Agent. Administrative Agent may resign at any time by giving notice thereof to Banks and Borrower. Upon any such resignation, Required Banks shall have the right to appoint a successor Administrative Agent. If no successor Administrative Agent shall have been so appointed by Required Banks and shall have accepted such appointment within thirty (30) days after the retiring Administrative Agent's giving of notice of resignation, then the retiring Administrative Agent may, on behalf of Banks, appoint a successor Administrative Agent which shall be a commercial bank organized under the Laws of the United States of America having combined capital and surplus of at least $100,000,000. Upon the acceptance of any appointment as Administrative Agent hereunder by a successor, such successor shall thereupon succeed to and become vested with all the Rights, powers, discretion, privileges, and duties of the retiring Administrative Agent, and the retiring Administrative Agent shall be discharged from its duties and obligations hereunder. After any retiring Administrative Agent's resignation hereunder as Administrative Agent, the provisions of this Article XIV shall continue in effect for its benefit in respect of any actions taken or omitted to be taken by it while it was acting as Administrative Agent. SECTION 14.8. Warrant Related Documents. Each Bank acknowledges that the Warrant Related Documents were each executed and delivered in connection with the Existing Credit Agreement and for the sole and exclusive benefit of The Chase Manhattan Bank, for itself and not as a Bank or as Administrative Agent hereunder, and each Bank acknowledges and agrees that such Bank (other than Existing Bank) shall not have any right, title or interest in, or with respect to, such Warrant Related Documents. ARTICLE XV MISCELLANEOUS SECTION 15.1. Notices. All notices, requests and other communications to any party hereunder shall be in writing (including bank wire, telecopy or similar writing) and shall be given, if to Administrative Agent or any Bank, at its address or telecopier number set forth on Schedule 1.1 hereto, and if given to Borrower, at its address or telecopy number set forth on the signature pages hereof (or in either case, at such other address or telecopy number as such party may hereafter specify for the purpose by notice to the other parties hereto). Each such notice, request or other communication shall be effective (a) if given by telecopy, when such telecopy is transmitted to the telecopy number specified in this Section 15.1 and the appropriate answerback is received or receipt is otherwise confirmed, (b) if given by mail, three (3) Domestic Business Days after deposit in the 63 70 mails with first class postage prepaid, addressed as aforesaid, or (c) if given by any other means, when delivered at the address specified in this Section 15.1; provided that notices to Administrative Agent under Article II shall not be effective until received. SECTION 15.2. No Waivers. No failure or delay by Administrative Agent or any Bank in exercising any Right, power or privilege hereunder or under any Note or other Loan Document shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any other Right, power or privilege. The Rights and remedies herein provided shall be cumulative and not exclusive of any Rights or remedies provided by Law or in any of the other Loan Documents. SECTION 15.3. Expenses. Borrower agrees to pay on demand all reasonable costs and expenses of Administrative Agent in connection with the syndication, preparation, execution, delivery, modification, restatement and amendment of this Agreement, the other Loan Documents, and the other documents to be delivered hereunder, including, without limitation, the reasonable fees and expenses of counsel for Administrative Agent (including the cost of internal counsel) with respect thereto and with respect to advising Administrative Agent as to its Rights and responsibilities under the Loan Documents. Borrower further agrees to pay on demand all reasonable costs and expenses of Administrative Agent and Banks, if any (including, without limitation, reasonable attorneys' fees and expenses and the cost of internal counsel), in connection with the enforcement (whether through negotiations, legal proceedings, or otherwise) of the Loan Documents and the other documents to be delivered hereunder. SECTION 15.4. Right of Set-off; Adjustments. (a) Upon the occurrence and during the continuance of any Event of Default, each Bank (and each of its Affiliates) is hereby authorized at any time and from time to time, to the fullest extent permitted by Law, to set-off and apply any and all deposits (general or special, time or demand, provisional or final) at any time held and other indebtedness at any time owing by such Bank (or any of its Affiliates) to or for the credit or the account of Borrower against any and all of the Obligations, irrespective of whether such Bank shall have made any demand under this Agreement or under any Note held by such Bank and although such obligations may be unmatured. Each Bank agrees promptly to notify Borrower after any such set-off and application made by such Bank; provided, however, that the failure to give such notice shall not affect the validity of such set-off and application. The Rights of each Bank under this Section 15.4 are in addition to any other Rights and remedies (including, without limitation, other Rights of set-off) that such Bank may have. (b) If any Bank (a "benefitted Bank") shall at any time receive any payment of all or part of the Loans owing to it, or interest thereon, or receive any collateral in respect thereof (whether voluntarily or involuntarily, by set-off, or otherwise), in a greater proportion than any such payment to or collateral received by any other Bank, if any, in respect of such other Bank's Loans owing to it, or interest thereon, such benefitted Bank shall purchase for cash from any such other Bank a participating interest in such portion of each such other Bank's Loans owing to it, or shall provide such other Banks with the benefits of any such collateral, or the proceeds thereof, as shall be necessary to cause such benefitted Bank to share the excess payment or benefits of such collateral or proceeds ratably with each other Bank; provided, however, that if all or any portion of such excess payment or benefits is thereafter recovered from such benefitted Bank, such purchase shall be 64 71 rescinded, and the purchase price and benefits returned, to the extent of such recovery, but without interest. Borrower agrees that any Bank so purchasing a participation from a Bank pursuant to this Section 15.4 may, to the fullest extent permitted by Law, exercise all of its Rights of payment (including the Right of set-off) with respect to such participation as fully as if such Person were the direct creditor of Borrower in the amount of such participation. SECTION 15.5. Amendments and Waivers. Any provision of this Agreement or any other Loan Document may be amended or waived if, but only if, such amendment or waiver is in writing and is signed by Borrower and Required Banks (and, if Article XIV or the Rights or duties of Administrative Agent are affected thereby, by Administrative Agent); provided that no such amendment or waiver shall, unless signed by each Bank directly affected thereby, (a) increase the Commitment of any Bank, (b) reduce the principal of or rate of interest on any Loan or any fees or other amounts payable hereunder, (c) postpone the Termination Date, the Revolver Conversion Date or any date fixed for the payment of any scheduled installment of principal of or interest on any Loan or any fees or other amounts payable hereunder or for the termination of any Commitment, (d) change the percentage of the Commitments or of the unpaid principal amount of the Notes, or the number of Banks which shall be required for Banks or any of them to take any action under this Section 15.5, or any other provision of this Agreement, or (e) release any guarantor of the Obligations or all or substantially all of the collateral securing the Obligations. SECTION 15.6. Survival. All representations, warranties and covenants made by any Credit Party herein or in any certificate or other instrument delivered by it or in its behalf under the Loan Documents shall be considered to have been relied upon by Banks and shall survive the delivery to Banks of such Loan Documents or the extension of the Loan (or any part thereof), regardless of any investigation made by or on behalf of Banks. The indemnity provided in Section 9.7 herein shall survive the repayment of all credit advances hereunder and/or the discharge or release of any Lien granted hereunder or in any other Loan Document, contract or agreement between Borrower or any other Credit Party and Administrative Agent or any Bank. SECTION 15.7. Limitation on Interest. Regardless of any provision contained in the Loan Documents, Banks shall never be entitled to receive, collect, or apply, as interest on the Loan, any amount in excess of the Maximum Lawful Rate, and in the event any Bank ever receives, collects or applies as interest any such excess, such amount which would be deemed excessive interest shall be deemed a partial prepayment of principal and treated hereunder as such; and if the Loan is paid in full, any remaining excess shall promptly be paid to Borrower. In determining whether or not the interest paid or payable under any specific contingency exceeds the Maximum Lawful Rate, Borrower and Banks shall, to the extent permitted under applicable Law, (a) characterize any nonprincipal payment as an expense, fee or premium rather than as interest, (b) exclude voluntary prepayments and the effects thereof, and (c) amortize, prorate, allocate and spread, in equal parts, the total amount of the interest throughout the entire contemplated term of the Notes, so that the interest rate is the Maximum Lawful Rate throughout the entire term of the Notes; provided, however, that if the unpaid principal balance thereof is paid and performed in full prior to the end of the full contemplated term thereof, and if the interest received for the actual period of existence thereof exceeds the Maximum Lawful Rate, Banks shall refund to Borrower the amount of such excess and, in such event, Banks shall not be subject to any penalties provided by any Laws 65 72 for contracting for, charging, taking, reserving or receiving interest in excess of the Maximum Lawful Rate. SECTION 15.8. Invalid Provisions. If any provision of the Loan Documents is held to be illegal, invalid, or unenforceable under present or future Laws effective during the term thereof, such provision shall be fully severable, the Loan Documents shall be construed and enforced as if such illegal, invalid, or unenforceable provision had never comprised a part thereof, and the remaining provisions thereof shall remain in full force and effect and shall not be affected by the illegal, invalid, or unenforceable provision or by its severance therefrom. Furthermore, in lieu of such illegal, invalid, or unenforceable provision there shall be added automatically as a part of the Loan Documents a provision as similar in terms to such illegal, invalid, or unenforceable provision as may be possible and be legal, valid and enforceable.
