Each borrowing or reborrowing made hereunder shall be evidenced by the Revolving Credit Notes, which shall be in the form of Exhibit A hereto and shall mature and bear interest as set forth in Section 4 hereof and in such Revolving Credit Notes. On the Effective Date, the Company shall issue and deliver to each Bank a Revolving Credit Note in the principal amount of such Banks' Commitment for the period beginning on the Effective Date in substitution for the promissory notes previously issued under the Prior Loan Agreement.

Subject to the terms and conditions of this Agreement, the Company may borrow, prepay pursuant to Section 4.1(c) and reborrow under this Section 2.1.

S/L/Cs shall only be issued for the account of the Company and only for purposes occurring in the ordinary course of business of the Company, and shall not be issued to guarantee any indebtedness of any Person other than the Company or any Subsidiary. Any S/L/C issued by the Agent for the Company outstanding as of the Effective Date shall be considered an Advance under this Agreement. For purposes of this Agreement, an S/L/C Advance shall be deemed outstanding in an amount equal to the sum of the maximum amount available to be drawn and not drawn under the related S/L/C on or after the date of determination and on or before the stated Expiry Date thereof plus the amount of any draws under the related S/L/C which have not been reimbursed. 2.4 Limit on Advances. Notwithstanding anything herein to the contrary (other than provisions of Section 3.1(a) permitting Revolving Credit Loans to be automatically made in the amount of any reimbursement obligation under an S/L/C), the Company shall not be entitled to obtain, and the Banks shall not be obligated to make, any Advance if on the proposed Advance Date the principal amount of such Advance, when added to the aggregate amount of all Advances then outstanding, would exceed the Available Portion. SECTION 3. The Advances 3.1 Disbursement of Advances. (a) The Company shall give notice to the Agent of each requested Advance in substantially the form of Exhibit D hereto, which notice shall be received by the Agent not later than 11:00 A.M. (Detroit time) (a) three Eurodollar Business Days prior to the proposed Advance Date in the case of any Eurodollar Rate Loan, (b) one Business Day prior to the proposed Advance Date in the case of all other Loans and (c) three Business Days prior to the Advance Date in the case of an S/L/C Advance, which notice shall specify whether a CD Rate Loan, Eurodollar Rate Loan, Prime Rate Loan or S/L/C Advance is requested and, in the case of each Fixed Rate Loan, the Interest Period to be initially applicable to such Loan. Each such notice shall be irrevocable and binding on the Company. The Agent shall provide notice of such requested Advance to each Bank on the same Business Day such notice is received from the Company and the Agent shall provide notice to such Bank on each date on which it honors a draft under any S/L/C, specifying the amount of such draft and any cost and expenses related thereto. If an S/L/C is requested, the Company shall deliver together with such notice a fully completed S/L/C Application with respect to such S/L/C. All obligations of the Company arising under any S/L/C Application shall be deemed obligations of the Company under this Agreement. The Agent will give each Bank oral notice (to be confirmed promptly in writing) on each day on which it honors a draft to it under any S/L/C, specifying the amount of such draft. Notwithstanding anything in any S/L/C Application to the contrary, unless the Company shall have made full payment (which shall include withdrawals 17 23 from deposits of cash cover for any S/L/C) to the Agent on the day of any draw under any S/L/C, the Company, the Agent and the Banks agree that the obligation of the Company to reimburse the Agent in respect of amounts drawn under any S/L/C (and any costs and expenses related thereto) shall be satisfied, on the date due, by disbursement of a Revolving Credit Loan bearing interest at the Adjusted Prime Rate in the amount to be so reimbursed. Such Revolving Credit Loan shall be disbursed notwithstanding any failure to satisfy any conditions for disbursement of any Loan set forth herein. (b) Subject to the terms and conditions of this Agreement, the proceeds of such requested Loan shall be made available to the Company by depositing the proceeds thereof, in immediately available funds, on the Advance Date for such Loan in an account maintained and designated by the Company at the principal office of the Agent and in the case of an S/L/C Advance, by delivery of the S/L/C to the Company or the beneficiary under such S/L/C, provided, however, that disbursements of Revolving Credit Loans made pursuant to the last sentence of Section 3.1(a) shall be made directly from each Bank in respect of the reimbursement and related obligations of the Company. Each Bank, on the Advance Date of each such Loan shall make its Pro Rata Share of such Loan available in immediately available funds at the principal office of the Agent for disbursement to the Company. Unless the Agent shall have received notice from any Bank prior to the date of any requested Loan under this Section 3.1 that such Bank will not make available to the Agent such Bank's Pro Rata Share, the Agent may assume that such Bank has made such share available to the Agent on the Advance Date of such Loan in accordance with this Section 3.1(b). If and to the extent such Bank shall not have so made such Pro Rata Share available to the Agent, the Agent may (but shall not be obligated, except as required under any S/L/C, to) make such amount available to the Company on the relevant Advance Date in the case of a Loan and to the beneficiary in the case of a draw under an S/L/C, and such Bank agrees to pay to the Agent forthwith on demand such amount together with interest thereon, for each day from the date such amount is made available to the Company or such beneficiary by the Agent until the date such amount is paid to the Agent, at a rate per annum equal to the rate at which overnight borrowings are available to the Agent from other banks in its regional federal funds market. If such Bank shall pay to the Agent such amount, such amount so paid shall constitute a Loan by such Bank as a part of such borrowing for purposes of this Agreement. The failure of any Bank to make its Pro Rata Share of any such Loan available to the Agent shall not relieve any other Bank of its obligations to make available its Pro Rata Share of such Loan on the Advance Date of such Loan, but no Bank shall be responsible for failure of any other Bank to make such Pro Rata Share available to the Agent on the Advance Date of any such Loan. 3.2 Conditions of Advances.

The Company shall elect in writing to the Banks the Elected Available Portion on the following dates: (a) the Effective Date, and (b) within five Business Days after receipt by the Company of each Borrowing Base determination. Each such election pursuant to the preceding sentence shall remain in effect from the date of such election until the date of the next available election. If the Company fails to make any such election, the Elected Available Portion shall be an amount equal to the Available Portion. Notwithstanding anything herein to the contrary, the Elected Available Portion shall not be less than the difference between the Borrowing Base minus the principal amount outstanding of the Private Placement Notes. If any Advance causes the total outstanding Advances (including such Advance) at any time to exceed the Elected Available Portion, the Elected Available Portion automatically shall be increased thereafter by such excess. 4.5 Fees. (a) The Company agrees to pay to the Agent, for the pro rata account of the Banks, a commitment fee computed at the rate of three-eighths of one percent (3/8%) per annum on the amount by which the Elected Available Portion (without giving effect to any reduction therein caused by the Borrowing Base limitations) exceeds the aggregate outstanding principal amount of the Loans, for the period from the Effective Date until the Termination Date or the earlier termination of the Credit. Said fee shall be paid quarterly, on the last day of each March, June, September and December commencing on the first such date after the Effective Date, and the date of each reduction or termination of the Credit, for the preceding period for which such fee has not been paid. (b) If any Advance causes the aggregate outstanding Advances, including such Advance, at any time to exceed the Elected Available Portion, the Company shall pay an 25 31 additional fee to the Agent, for its account and the account of the Banks, on the date of such Advance equal to three-eighths of one percent (3/8%) per annum, computed for the period from and including the date of the most recent election by the Company of the Elected Available Portion under Section 4.4 hereof to and including the date of such Advance, of the amount of such excess. (c) The Company agrees to pay to the Agent a fee computed at the rate of one and one-quarter of one percent (1-1/4%) per annum (with the Agent retaining for its own account one-quarter of one percent per annum of such fee, and with the remainder of such fee being paid to the Banks according to their Pro Rata Share) of the maximum amount available to be drawn from time to time under each S/L/C for a period from and including the date of the issuance of such S/L/C to and including the Stated Expiry Date of such S/L/C. Such fee shall be payable annually in advance on or before the date of the issuance of each S/L/C and on each anniversary thereof if such S/L/C is then outstanding. Such fees are non-refundable and the Company shall not be entitled to any rebate of any portion thereof if such S/L/C does not remain outstanding through the end of the annual or shorter period for which such fee was paid. Notwithstanding the foregoing, it is understood that if the period from and including the date of the issuance of an S/L/C to and including the Stated Expiry Date of such S/L/C is less than one year, the fee payable hereunder will be payable for the period of time during which such S/L/C may be outstanding and not payable for a one year period. The Company further agrees to pay to the Agent, on demand, such other customary administrative fees, charges and expenses of the Agent in respect of the issuance, negotiation, acceptance, amendment, transfer and payment of such S/L/C or otherwise payable pursuant to the S/L/C Application and related documentation under which such S/L/C is issued. 4.6 Cash Cover of S/L/Cs. The Company may reduce all or any part of the outstanding S/L/C Advances (provided that such reduction is in a minimum amount of $100,000 and in a whole multiple of $100,000) prior to any Expiry Date with respect to any S/L/C by the provision of cash cover in a manner satisfactory to the Banks to meet the maximum contingent obligations of the Banks under such S/L/C. Upon the delivery of such cash cover to the Agent, the Banks shall have a lien thereon and a security interest therein and in all interest and other proceeds thereof to secure the obligations of the Company to the Banks in connection with this Agreement, and the Company shall provide to the Banks such evidence as the Banks may request to establish the legality, validity and enforceability of such lien and security interest. The Agent agrees to deposit such cash cover in an interest bearing account at the main office of the Agent or in an investment acceptable to the Agent. The amount of such S/L/C Advance shall be reduced by the amount of cash cover deposited. If the Company shall have so provided to the Banks cash cover for any S/L/C, the Banks shall make available to the Company promptly after the Expiry Date of such S/L/C the amount of any such cash cover and interest thereon in excess of amounts thereof required by the Banks and the Agent, if any, to satisfy and pay any obligations of the Company to the Banks then due and payable. 4.7 Indemnity. The Company assumes all risks of the acts or omissions of any beneficiary under any S/L/C issued pursuant to this Agreement with respect to the use by such 26 32 beneficiary of such S/L/C. In addition to all undertakings and indemnities of the Company contained in the S/L/C Applications delivered by the Company to the Agent pursuant to Section 3.1, the Company acknowledges that neither the Banks, the Agent nor any of their officers or directors shall be liable or responsible for (i) the use which may be made of any S/L/C or for any acts or omissions of any beneficiary in connection therewith, (ii) the validity, sufficiency or genuineness of any documents delivered in connection with any S/L/C, or of any endorsements thereon, even if such documents should in fact prove to be in any or all respects invalid, insufficient, fraudulent or forged, or (iii) any other circumstances whatsoever in connection with honoring or dishonoring any S/L/C, except that the Company shall have a claim against the Agent, and the Agent shall be liable to the Company, to the extent, but only to the extent, of any direct damages suffered by the Company which the Company proves were caused by the Agent's wrongful dishonor of a draft under any S/L/C after presentation to the Agent by the beneficiary thereunder of documents strictly complying with the terms and conditions of such S/L/C or by the Agent's wrongful honor of a draft under any S/L/C after presentation to the Agent by the beneficiary thereunder of documents not substantially complying with the terms and conditions of such S/L/C, but in no event shall the Banks or the Agent be liable for any special, punitive, exemplary or consequential damages. In furtherance and not in limitation of the foregoing, the Agent may accept documents that appear on their face to be in order, without responsibility for further investigation regardless of any notice or information to the contrary. The Company hereby indemnifies the Banks and the Agent and agrees to keep the Banks and the Agent at all times indemnified against all liabilities which the Banks may incur or which may be claimed against any Bank or the Agent by any Person or entity by reason of or relating to any matters arising in connection with any S/L/C or any of the transactions contemplated thereby, provided, however, that the Company shall not be required to so indemnify any Bank or the Agent for any such liabilities or claims to the extent, but only to the extent, caused by such Bank's or the Agent's gross negligence or willful misconduct under this Agreement. If any law, rule, regulation, directive or request of general applicability, or the interpretation thereof by any court or administrative or governmental authority charged with the administration thereof (whether or not having the force of law), shall either (i) impose, modify or deem applicable any taxation, reserve, special deposit or any other requirement or condition with respect to S/L/Cs issued hereunder (including without limitation the imposition of any reserve requirement by the Federal Deposit Insurance Corporation in respect of any S/L/C), or (ii) impose on any Bank any other requirement or condition regarding this Agreement or its S/L/C issued hereunder or any of the transactions contemplated hereby, and as a result of any such event, or by reason of such Bank's compliance therewith, the cost to such Bank of issuing or maintaining its S/L/C or related obligation, or its participation in related obligations of the Company, or engaging in any of the transactions contemplated hereby shall be increased, then, upon demand by such Bank, the Company agrees to pay immediately to such Bank, from time to time, additional amounts which shall be sufficient to compensate such Bank for such increased cost, together with interest on each such amount from the date demanded until payment in full thereof at the Overdue Rate, provided, however, that any such claims shall not duplicate any claims under Section 5.1. Such amounts shall be due and payable on the Business Day following presentation to the Company by such Bank of a certificate as to such increased cost incurred by such Bank, prepared by such 27 33 Bank and showing the calculation of such cost in reasonable detail, which calculation shall be conclusive absent manifest error in computation. 4.8 Payment Method. All payments to be made by the Company hereunder will be made in Dollars and in immediately available funds to the Agent at its address set forth in Section 10.2 not later than 11:00 a.m. Detroit time on the date on which such payment shall become due. Payments received after 11:00 a.m. Detroit time shall be deemed to be payments made prior to 11:00 a.m. Detroit time on the next succeeding Business Day. At the time of making each such payment, the Company shall specify to the Agent that obligation of the Company hereunder to which such payment is to be applied, or, in the event that the Company fails to so specify or if an Event of Default shall have occurred and be continuing, the Agent may apply such payments as it may determine in its sole discretion. On the day such payments are received, the Agent shall remit to the Banks their respective Pro Rata Shares of such payments, in immediately available funds. 4.9 No Setoff or Deduction. All payments of principal of and interest on the Advances and other amounts payable by the Company hereunder shall be made by the Company without setoff or counterclaim, and free and clear of, and without deduction or withholding for, or on account of, any present or future taxes, levies, imposts, duties, fees, assessments, or other charges of whatever nature, imposed by any governmental authority, or by any department, agency or other political subdivision or taxing authority. 4.10 Payment on Non-Business Day; Payment Computations. Except as otherwise provided in this Agreement to the contrary, whenever any installment of principal of, or interest on, any Advance outstanding hereunder or any other amount due hereunder, becomes due and payable on a day which is not a Business Day, the maturity thereof shall be extended to the next succeeding Business Day and, in the case of any installment of principal, interest shall be payable thereon at the rate per annum determined in accordance with this Agreement during such extension. Computations of interest and other amounts due under this Agreement shall be made on the basis of a year of 360 days for the actual number of days elapsed, including the first day but excluding the last day of the relevant period. 4.11 Agent's Fees. The Company agrees to pay to the Agent agency, engineering, closing and servicing fees for its services under this Agreement in such amounts as may from time to time be agreed upon by the Company and the Agent. Notwithstanding anything herein to the contrary, unless otherwise agreed to by the Agent, such fees shall be retained solely by the Agent. SECTION 5. Yield Protection and Contingencies 5.1 Additional Costs. (a) In the event that any applicable law, treaty, rule or regulation (whether domestic or foreign) now or hereafter in effect and whether or not presently applicable to any Bank, or any interpretation or administration thereof by any governmental 28 34 authority charged with the interpretation or administration thereof, or compliance by any Bank with any request or directive of any such authority (whether or not having the force of law), shall (i) affect the basis of taxation of payments to any Bank of any amounts payable by the Company under this Agreement (other than taxes imposed on the overall net income of any Bank by the jurisdiction, or by any political subdivision or taxing authority of any such jurisdiction, in which such Bank has its principal office), or (ii) shall impose, modify or deem applicable any risk-based capital, reserve, special deposit, deposit insurance or similar requirement against assets of, deposits with or for the account of, or credit extended by such Bank, or (iii) shall impose any other condition with respect to this Agreement, the Notes or the Advances, and the result of any of the foregoing is to increase the cost to any Bank of making or maintaining any Fixed Rate Loan or to reduce the amount of any such receivable by such Bank thereon, then the Company shall pay to such Bank, from time to time, upon request by such Bank additional amounts sufficient to compensate such Bank for such increased cost or reduced sum receivable to the extent such Bank is not compensated therefor in the computation of the interest rate applicable to such Fixed Rate Loan. All claims under this Section 5.1(a) and under Section 5.1(b) shall not duplicate any claims under Section 4.7. A detailed statement as to the amount of such increased cost or reduced sum receivable, prepared in good faith and submitted by such Bank to the Company, shall be conclusive and binding for all purposes absent manifest error in computation. The Banks agree that such costs under this Section 5.1(a) and the compensation requested under Section 5.1(b) shall (i) not be requested if they are not requested of other borrowers similar to the Company, provided that the Banks' determination of similar borrowers shall be conclusive and binding, and (ii) only be charged when actually incurred by any Bank, and if any Bank is refunded such costs after charging the Company for such costs, then such Bank shall refund to the Company such costs to the extent such Bank receives a refund, net of any costs or expenses incurred in pursuing such refund. (b) In the event that any applicable law, treaty, rule or regulation (whether domestic or foreign) now or hereafter in effect and whether or not presently applicable to any Bank or the Agent, or any interpretation or administration thereof by any governmental authority charged with the interpretation or administration thereof, or compliance by any Bank or the Agent with any guideline, request or directive of any such authority (whether or not having the force of law), affects or would affect the amount of capital required or expected to be maintained by such Bank or the Agent or any corporation controlling such Bank or the Agent and such Bank or the Agent, as the case may be, determines that the amount of such capital is increased by or based upon the existence of such Bank's or the Agent's obligations hereunder and such increase has the effect of reducing the rate of return on such Bank's or the Agent's capital as a consequence of its obligations hereunder to a level below that which such Bank or the Agent could have achieved but for such circumstances (taking into consideration its policies with respect to capital adequacy) by an amount deemed by such Bank or the Agent to be material, then the Company shall pay to such Bank or the Agent, as the case may be, from time to time, upon request by such Bank (with a copy of such request to be provided to the Agent) or the Agent, additional amounts sufficient to compensate such Bank or the Agent for any increase in the amount of capital and reduced rate of return which such Bank or the Agent reasonably determines to be allocable to the existence of such Bank's or the Agent's obligations hereunder. A statement as 29 35 to the amount of such compensation, prepared in good faith and in reasonable detail by such Bank or the Agent, as the case may be, and submitted by such Bank or the Agent to the Company, shall be conclusive and binding for all purposes absent manifest error in computation. 5.2 Limitation of Requests and Elections. Notwithstanding any other provision of this Agreement to the contrary, if, upon receiving a request for a Fixed Rate Loan pursuant to Section 3.1, or a request for a continuation of a Fixed Rate Loan as a Fixed Rate Loan of the then existing type pursuant to Section 3.4, or conversion of a Loan to a Fixed Rate Loan pursuant to Section 3.4, (a) in the case of any Eurodollar Rate Loan or CD Rate Loan, deposits in Dollars for periods approximately equal to the Interest Period elected by the Company are not available to any Bank in the relevant interbank or secondary market, or (b) the CD Rate or the Eurodollar Rate, as the case may be, for periods approximately equal to the Interest Period elected by the Company will not adequately and fairly reflect the cost to any Bank of making or maintaining the related CD Rate Loan or Eurodollar Rate Loan, as the case may be, or (c) by reason of national or international financial, political or economic conditions or by reason of any applicable law, treaty, rule or regulation (whether domestic or foreign) now or hereafter in effect and whether or not presently applicable to any Bank, or the interpretation or administration thereof by any governmental authority charged with the interpretation or administration thereof, or compliance by any Bank with any request or directive of such authority (whether or not having the force of law), including without limitation exchange controls, it is impracticable, unlawful or impossible for any Bank (i) to make the relevant Fixed Rate Loan or (ii) to continue such Fixed Rate Loan as a Fixed Rate Loan of the then existing type or (iii) to convert a Loan to such a Fixed Rate Loan, then the Company shall not be entitled, so long as such circumstances continue, to request from each such Bank a Fixed Rate Loan of the affected type pursuant to Section 3.1 or a continuation of or conversion to a Fixed Rate Loan of the affected type pursuant to Section 3.4; provided, however, that nothing in this Section 5.2 shall affect such Bank's obligations under this Agreement to make or continue a Prime Rate Loan. In the event that such circumstances no longer exist, such Bank shall again accept, provided that the other terms and conditions of this Agreement are satisfied, requests for Fixed Rate Loans of the affected type pursuant to Section 3.1, and requests for continuations of and conversions to Fixed Rate Loans of the affected type pursuant to Section 3.4. 5.3 Illegality and Impossibility. In the event that any applicable law, treaty, rule or regulation (whether domestic or foreign) now or hereafter in effect and whether or not presently applicable to any Bank, or any interpretation or administration thereof by any governmental authority charged with the interpretation or administration thereof, or compliance by any Bank with any request or directive of such authority (whether or not having the force of law), including without limitation exchange controls, or any change in such law, treaty, rule, regulation, interpretation or administration shall make it unlawful or impossible for any Bank to maintain any Fixed Rate Loan under this Agreement, the Company shall upon receipt of notice thereof from such Bank, repay in full to such Bank the then outstanding principal amount of each Fixed Rate Loan so affected together with all accrued interest thereon to the date of payment and all amounts due to such Bank under Section 5.4 (a) on the last day of the then current Interest Period applicable to such Loan if such Bank may lawfully continue to maintain 30 36 such Loan to such day, or (b) immediately if such Bank may not continue to maintain such Loan to such day. 5.4 Indemnification. If the Company makes any payment of principal with respect to any Fixed Rate Loan on any date other than the last day of an Interest Period applicable thereto (whether pursuant to Section 4.1(d), Section 5.3, Section 7.1(i), Section 8.2 or otherwise), or if the Company fails to borrow any Fixed Rate Loan after notice has been given in accordance with Section 3.1, or fails to make any payment of principal or interest in respect of a Fixed Rate Loan when due, the Company shall reimburse each Bank on demand for any resulting loss or expense incurred by each such Bank, including without limitation any loss incurred in obtaining, liquidating or employing deposits from third parties. A detailed statement as to the amount of such loss or expense, certified by such Bank as having been prepared in good faith and as being accurate to the best of such Bank's knowledge and submitted by such Bank to the Company, shall be conclusive and binding for all purposes absent manifest error in computation.

(a) Upon the occurrence and during the continuance of any Event of Default, the Agent shall, upon being directed to do so by the Majority Banks or, in the case of any Event of Default arising under Section 8.1(a) upon being directed to do so by Banks holding not less than 51% of the principal amount of the Advances then outstanding (or 51% of the Commitments if no Advances are then outstanding), by notice to the Company terminate the Commitments or declare the outstanding principal of, and accrued interest on, the Notes and all other amounts due under this Agreement, and cash cover with respect to any outstanding S/L/C, to be immediately due and payable, or all of the above, whereupon the Commitments shall terminate forthwith and all such amounts shall become immediately due and payable, or both, as the case may be, provided that in the case of any event or condition described in Section 8.1(h) with respect to the Company, the Commitments shall automatically terminate forthwith and all such amounts shall automatically become immediately due and payable without notice; in each case without demand, presentment, protest, diligence, notice of dishonor or other formality, all of which are hereby expressly waived. (b) Upon the occurrence and during the continuance of such Event of Default, the Agent shall, upon being directed to do so by the Majority Banks or, in the case of any Event of Default arising under Section 8.1(a) upon being directed to do so by Banks holding not less than 51% of the principal amount of the Advances then outstanding (or 51% of the Commitments if no Advances are then outstanding), in addition to the remedies provided in Section 8.2(a), enforce its rights either by suit in equity, or by action at law, or by other 48 54 appropriate proceedings, whether for the specific performance (to the extent permitted by law) of any covenant or agreement contained in this Agreement or in any then outstanding Note or any S/L/C Application or in aid of the exercise of any power granted in this Agreement, any then outstanding Note or any S/L/C Application, and may enforce the payment of any then outstanding Notes and any of the other rights of the Agent and the Banks available at law or in equity. (c) Upon the occurrence and during the continuance of any Event of Default hereunder, each Bank may at any time and from time to time, without notice to the Company (any requirement for such notice being expressly waived by the Company) set off and apply against any and all of the obligations of the Company now or hereafter existing under this Agreement, any of the Notes or the S/L/C Applications, 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 to or for the credit or the account of the Company and any property of the Company from time to time in possession of such Bank, irrespective of whether or not any Bank shall have made any demand hereunder and although such obligations may be contingent and unmatured. The rights of the Banks under this Section 8.2(c) are in addition to other rights and remedies (including, without limitation, other rights of setoff) which the Banks may have. SECTION 9. The Agent and the Banks 9.1 Appointment of Agent. NBD Bank, N.A. is hereby appointed Agent for the Banks and accepts such appointment and agrees to act as such upon the conditions herein set forth. The Agent shall have no duties or responsibilities except those expressly set forth in this Agreement, and shall not, by reason of this Agreement, have a fiduciary relationship with any Bank. 9.2 Scope of Agency. Neither the Agent nor any of its directors, officers or agents shall be liable to the Banks for any action taken or omitted by any of them hereunder or under the Notes or the S/L/C's, except for its, his or her own gross negligence or willful misconduct and except as provided in Section 9.3 hereof; or be responsible to the Banks for any recitals, warranties or representations herein or in the Notes or the S/L/C Applications or for the execution or validity of this Agreement, the Notes or the S/L/C Applications; or be required to make any inquiry concerning the performance by the Company of any of its obligations under this Agreement, the Notes or the S/L/C Applications. In the absence of gross negligence or willful misconduct, the Agent shall be entitled to rely, without liability therefor, upon any certificate or other document or other communication believed by it to be genuine and correct and to have been signed or sent by the proper officer or Person and upon the advice of legal counsel (which may be legal counsel for the Company), independent public accountants and other experts concerning all matters pertaining to the agency. To the extent that the Company shall fail to pay or to reimburse the Agent for the payment of the same, each Bank shall reimburse the Agent in accordance with such Bank's Pro Rata Share, and any such amount so paid shall be immediately due and payable to the Banks by the Company. The Banks shall 49 55 indemnify the Agent ratably in accordance with their Pro Rata Share of the Commitments for any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever which may be imposed on, incurred by or asserted against the Agent in any way relating to or arising out of this Agreement or the transactions contemplated hereby, provided that no Bank shall be liable for any of the foregoing to the extent they arise from the Agent's gross negligence or willful misconduct. 9.3 Duties of Agent. In carrying out the agency, the Agent shall have only the duties and responsibilities expressly set forth in this Agreement and in performing such duties and responsibilities the Agent shall exercise the same degree of care as it would if the Loans were entirely for its own account, but the Agent shall not be deemed to have knowledge of the occurrence of any Event of Default, or any event or condition which with notice or lapse of time, or both, could become such an Event of Default and need not take or continue any action with respect thereto or toward the enforcement of this Agreement, the Notes or the S/L/C Applications, nor prosecute or defend any suit with respect to this Agreement, the Notes or the S/L/C Applications, unless directed to do so by the Banks and unless indemnified to its satisfaction against any loss, cost, liability or expense which it might incur as a consequence of taking such action. The Agent may employ agents and attorneys and shall not be answerable for the negligence or misconduct of any such agents or attorneys selected by it with reasonable care. The 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 the Agent hereunder. Each Bank agrees that it has, independently and without reliance on the Agent or any other Bank, and based on such documents and information as it has deemed appropriate, made its own credit analysis of the Company and its Subsidiaries in connection with its decision to enter into this Agreement and that it will, independently and without reliance upon the 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 this Agreement. 9.4 Resignation of Agent. The Agent may resign as such at any time upon thirty days' prior written notice to the Company and the Banks. In the event of any such resignation, the Banks shall, by an instrument in writing delivered to the Company and the Agent, appoint a successor which shall be an incorporated bank or trust company. If a successor is not so appointed or does not accept such appointment at least five days before the Agent's resignation becomes effective, the Agent may appoint a temporary successor to act until such appointment by the Banks is made and accepted. Any successor to the Agent shall be reasonably acceptable to the Company, have adequate expertise in oil and gas lending and execute and deliver to the Company and the Banks an instrument accepting such appointment and thereupon such successor Agent, without further act, deed, conveyance or transfer shall become vested with all of the properties, rights, interests, powers, authorities and obligations of its predecessor hereunder with like effect as if originally named as Agent hereunder. Upon request of such successor Agent, the Company and the Agent ceasing to act shall execute and deliver such instruments of conveyance, assignment and further assurance and do such other things as may reasonably be 50 56 required for more fully and certainly vesting and confirming in such successor Agent all such properties, rights, interests, powers, authorities and obligations. 9.5 Pro Rata Sharing by Banks. Each Bank agrees with every other Bank that, in the event that it shall receive and retain any payment on account of the Company's obligations under this Agreement, the Notes or the S/L/C Applications in a greater proportion than that received by any other Bank, whether such payment be voluntary, involuntary or by operation of law, by application of set-off of any indebtedness or otherwise, then such Bank shall promptly purchase from the other Banks, without recourse, for cash and at face value, ratably in accordance with its Pro Rata Share, in such an amount that each Bank shall have received payment in respect of such obligations in accordance with its Pro Rata Share; provided, that if any such purchase be made by any Bank and if any such excess payment relating thereto or any part thereof is thereafter recovered from such Bank, appropriate adjustment in the related purchase from the other Banks shall be made by rescission and restoration of the purchase price as to the portion of such excess payment so recovered. It is further agreed that, to the extent there is then owing by the Company to any Bank indebtedness other than that evidenced by this Agreement, the Notes and the S/L/C Applications to which such Bank may apply any involuntary payments of indebtedness by the Company, including those resulting from exercise of rights of set-off or similar rights, such Bank shall apply all such involuntary payments first to obligations of the Company to the Banks hereunder and under the Notes and the S/L/C Applications and then to such other indebtedness owed to it by the Company. In addition, it is further agreed that any and all proceeds resulting from a sale or other disposition of any collateral which may be hereafter granted for the benefit of the Banks to secure the obligations of the Company hereunder, shall be applied first to obligations of the Company to the Banks hereunder and under the Notes and the S/L/C Applications, and then ratably to any other indebtedness owed by the Company to the Banks which is secured by such collateral. 9.6 Determination of Borrowing Base, Etc. (a) Any determination of the Borrowing Base shall be made by the Agent, and then shall be submitted to the Banks. If any Bank(s) holding not less than 20% of the aggregate principal amount of the Advances then outstanding, or 20% of the Commitments if no Advances are outstanding (the "20% Banks") determines that such determination made by the Agent is understated or overstated by more than 5% based on the determination of the Borrowing Base by each Bank, in accordance with its customary and standard practices in lending to oil and gas companies, such 20% Banks may object to such determination by the Agent provided such objection is made within fifteen Business Days of such 20% Banks receiving such determination. If the Agent and the 20% Banks cannot mutually agree upon a determination of the Borrowing Base within three days of such objection, then the Borrowing Base shall be immediately redetermined and equal to the weighted average of the determinations of the Borrowing Base of each Bank, weighted in accordance with their Pro Rata Share. Such determination of the Borrowing Base and related determinations shall then become effective, subject to any subsequent reduction that may occur pursuant to Section 9.6(b) hereof. The Borrowing Base may be re-evaluated from time to time as determined by the Banks, and will be re- evaluated upon the request of the Company (provided that the Company cannot request any re-evaluation of the Borrowing Base more than two times in any twelve month period), but 51 57 will be re-evaluated upon receipt of any document referred to in Section 7.1(d)(vi) hereof or the occurrence of any event referred to in Section 7.2(h)(iii) or 7.1(d)(viii) hereof and, in addition, at least twice annually as follows: promptly upon receipt of the annual reserve report referred to in Section 7.1(d)(ix) hereof and each six months thereafter. Except for the scheduled re-evaluations of the Borrowing Base upon receipt of the annual reserve report and each six months thereafter, each Bank requesting a re-evaluation of the Borrowing Base agrees to give notice to the Company of such request. The Company acknowledges that the Borrowing Base may also be re-evaluated upon the request of the holders of at least 66-2/3% in aggregate principal amount of the outstanding Private Placement Notes one time in any twelve month period and as reasonably requested by the holders of at least 30% in aggregate principal amount of the outstanding Private Placement Notes after an Event of Default under the Private Placement Agreement, under the conditions described in the letter agreement of approximately even date herewith among the Agent, the Banks and a Private Placement Noteholders, and the Company agrees that the expenses of any such re-evaluation at the request of such holders shall be borne by the Company. (b) Upon any determination by the Agent and the Banks pursuant to Section 9.6(a) hereof, the Company shall submit such determination to the Private Placement Noteholders, and unless the Majority Private Placement Noteholders determine that the Borrowing Base determination determined by the Agent and the Banks as described in Section 9.6(a) is overstated by more than 5% and notify the Agent and the Banks in writing of such objection within ten business days of the submission of such Borrowing Base determination to the Private Placement Noteholders, the determination of the Borrowing Base by the Agent and the Banks described above shall be final. If the Majority Private Placement Noteholders do so timely object, such objection must be accompanied by appropriate calculations and engineering support for such objection and the Banks and the Private Placement Noteholders thereafter shall negotiate in good faith toward the determination of a new Borrowing Base and the Agent shall resubmit additional determinations of the Borrowing Base until the Majority Lenders approve a Borrowing Base. Until such agreement has been reached among the Majority Lenders, the determination of the Borrowing Base pursuant to Section 9.6(a) shall remain in effect. Under no circumstances may the Private Placement Noteholders effect an increase in the Borrowing Base determined under Section 9.6(a). SECTION 10. Miscellaneous 10.1 Amendments; Etc. This Agreement and any term or provision hereof may be amended, waived or terminated by an instrument in writing executed by the Company and the Majority Banks, provided, that, notwithstanding anything in this Agreement to the contrary, except by an instrument in writing executed by the Company and all of the Banks, no such amendment, waiver or termination shall: (a) Authorize or permit the extension of the time or times of payment of the principal of, or interest on, the Notes or the obligations under the S/L/C Applications or any of them, or 52 58 the reduction in principal amount thereof or the rate of interest thereon, or any fees payable hereunder, or increase the Commitment of any Bank without such Bank's consent or increase the aggregate Commitments of all Banks to an amount greater than $135,000,000, or increase the aggregate Commitments beyond $110,000,000 without making modifications, if any, to this Agreement necessary to insure that NBD Bank, N.A., Bank of Montreal and Banque Paribas each qualify as a 20% Bank under Section 9.6, or amend this Section 10.1 or the definition of Majority Banks; or (b) Any such amendment, waiver or termination shall be effective only in the specific instance and for the specific purpose for which given. 10.2 Notices. (a) Except as otherwise provided in Section 10.2(c) hereof, all notices, requests, consents and other communications hereunder shall be in writing and shall be delivered or sent to the Company, the Banks and the Agent at the respective addresses for notices set forth on the signature pages hereof, or to such other address as may be designated by the Company, the Agent or any Bank by notice to the other parties hereto. All notices shall be deemed to have been given at the time of actual delivery thereof to such address, or if sent by the Agent or any Bank to the Company by certified or registered mail, postage prepaid, to such address, on the fifth day after the date of mailing. (b) Notices by the Company to the Agent with respect to requests for Advances pursuant to Section 3.1 and notices of prepayment pursuant to Section 4.1(c) shall be irrevocable and binding on the Company.

Any such notice given by telephone, telex or facsimile transmission shall be deemed effective upon receipt thereof by the party to whom such notice is given. 10.3 Conduct No Waiver; Remedies Cumulative. No course of dealing on the part of the Agent or the Banks, nor any delay or failure on the part of the Agent or any Bank in exercising any right, power or privilege hereunder shall operate as a waiver of such right, power or privilege or otherwise prejudice the Agent's or the Banks' rights and remedies hereunder; nor shall any single or partial exercise thereof preclude any further exercise thereof or the exercise of any other right, power or privilege. No right or remedy conferred upon or reserved to the Agent or the Banks under this Agreement is intended to be exclusive of any other right or remedy, and every right and remedy shall be cumulative and in addition to every other right or remedy given hereunder or now or hereafter existing under any applicable law. Every right and remedy given by this Agreement or by applicable law to the Agent or the Banks may be exercised from time to time and as often as may be deemed expedient by them. 53 59 10.4 Reliance on and Survival of Various Provisions. All terms, covenants, agreements, representations and warranties of the Company made herein or in any certificate or other document delivered pursuant hereto shall be deemed to be material and to have been relied upon by the Banks, notwithstanding any investigation heretofore or hereafter made by any Bank or on any Bank's behalf, and those covenants and agreements of the Company set forth in Section 10.5 hereof shall survive the repayment in full of the Loans and other obligations of the Company hereunder and under S/L/C Applications and the termination of the Commitment. 10.5 Expenses; Indemnification.

(a) This Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns, provided that the Company may not, without the prior consent of the Majority Banks, assign its rights or obligations hereunder or under the Notes and the Banks shall not be obligated to make any Advance hereunder to any entity other than the Company. (b) Any Bank may sell a participation interest to any financial institution or institutions, and such financial institution or institutions may further sell, a participation interest (undivided or divided) in, the Advances and such Bank's rights and benefits under this Agreement and the Notes and to the extent of that participation, such participant or participants shall have the same rights and benefits against the Company under Section 8.2(c) as it or they would have had if participation of such participant or participants were the Bank making the Advances to the Company hereunder, provided, however, that (i) such Bank's obligations under this Agreement shall remain unmodified and fully effective and enforceable against such Bank, (ii) such Bank shall remain solely responsible to the other parties hereto for the performance of such obligations, (iii) such Bank shall remain the holder of its Note for all purposes of this Agreement, (iv) the Company, the Agent and the other Banks shall continue to deal solely and directly with such Bank in connection with such Bank's rights and obligations under this Agreement, and (v) such Bank shall not grant to its participant any rights to consent or withhold consent to any action taken by such Bank or the Agent under this Agreement other than action requiring the consent of all of the Banks hereunder. The Agent from time to time in its sole discretion may appoint agents for the purpose of servicing and administering this Agreement and 55 61 the transactions contemplated hereby and enforcing or exercising any rights or remedies of the Agent provided under this Agreement, the Notes, or otherwise. In furtherance of such agency, the Agent may from time to time direct that the Company provide notices, reports and other documents contemplated by this Agreement (or duplicates thereof) to such agent. The Company hereby consents to the appointment of such agent and agrees to provide all such notices, reports and other documents and to otherwise deal with such agent acting on behalf of the Agent in the same manner as would be required if dealing with the Agent itself. (c) Each Bank may, with the prior consent of the Company and the Agent, assign to one or more banks or other entities all or a portion of its rights and obligations under this Agreement (including, without limitation, all or a portion of its Commitment, the Advances owing to it and the Note or Notes held by it); provided, however, that (i) each such assignment shall be of a uniform, and not a varying, percentage of all rights and obligations, (ii) except in the case of an assignment of all of a Bank's rights and obligations under this Agreement, (A) the amount of the Commitment of the assigning Bank being assigned pursuant to each such assignment (determined as of the date of the Assignment and Acceptance with respect to such assignment) shall in no event be less than $5,000,000, and in integral multiples of $1,000,000 thereafter, or such lesser amount as the Company and the Agent may consent to and (B) after giving effect to each such assignment, the amount of the Commitment of the assigning Bank shall in no event be less than $5,000,000, and (iii) the parties to each such assignment shall execute and deliver to the Agent, for its acceptance and recording in the Register, an Assignment and Acceptance in the form of Exhibit L hereto (an "Assignment and Acceptance"), together with any Note or Notes subject to such assignment and a processing and recordation fee of $3,000. Upon such execution, delivery, acceptance and recording, from and after the effective date specified in such Assignment and Acceptance, (x) the assignee thereunder shall be a party hereto and, to the extent that rights and obligations hereunder have been assigned to it pursuant to such Assignment and Acceptance, have the rights and obligations of a Bank hereunder and (y) the Bank assignor thereunder shall, to the extent that rights and obligations hereunder have been assigned by it pursuant to such Assignment and Acceptance, relinquish its rights and be released from its obligations under this Agreement (and, in the case of an Assignment and Acceptance covering all of the remaining portion of an assigning Bank's rights and obligations under this Agreement, such Bank shall cease to be a party hereto). (d) By executing and delivering an Assignment and Acceptance, the Bank assignor thereunder and the assignee thereunder confirm to and agree with each other and the other parties hereto as follows: (i) other than as provided in such Assignment and Acceptance, such assigning Bank makes no representation or warranty and assumes no responsibility with respect to any statements, warranties or representations made in or in connection with this Agreement or the execution, legality, validity, enforceability, genuineness, sufficiency or value of this Agreement or any other instrument or document furnished pursuant hereto; (ii) such assigning Bank makes no representation or warranty and assumes no responsibility with respect to the financial condition of the Company or the performance or observance by the Company of any of its obligations under this Agreement or any other instrument or document furnished pursuant hereto; (iii) such assignee confirms that it has received a copy of this Agreement, together with 56 62 copies of the financial statements referred to in Section 6.6 and such other documents and information as it has deemed appropriate to make its own credit analysis and decision to enter into such Assignment and Acceptance; (iv) such assignee will, independently and without reliance under the Agent, such assigning Bank or any other Bank and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under this Agreement; (v) such assignee appoints and authorizes the Agent to take such action as agent on its behalf and to exercise such powers and discretion under this Agreement as are delegated to the Agent by the terms hereof, together with such powers and discretion as are reasonably incidental thereto; and (vi) such assignee agrees that it will perform in accordance with their terms all of the obligations that by the terms of this Agreement are required to be performed by it as a Bank. (e) The Agent shall maintain at its address designated on the signature pages hereof a copy of each Assignment and Acceptance delivered to and accepted by it and a register for the recordation of the names and addresses of the Banks and the Commitment of, and principal amount of the Advances owing to, each Bank from time to time (the "Register"). The entries in the Register shall be conclusive and binding for all purposes, absent manifest error, and the Company, the Agent and the Banks may treat each Person whose name is recorded in the Register as a Bank hereunder for all purposes of this Agreement. The Register shall be available for inspection by the Company or any Bank at any reasonable time and from time to time upon reasonable prior notice. (f) Upon its receipt of an Assignment and Acceptance executed by an assigning Bank and an assignee, together with any Note or Notes subject to such assignment, the Agent shall, if such Assignment and Acceptance has been completed, (i) accept such Assignment and Acceptance, (ii) record the information contained therein in the Register and (iii) give prompt notice thereof to the Company. Within five Business Days after its receipt of such notice, the Company, at its own expense, shall execute and deliver to the Agent in exchange for the surrendered Note or Notes a new Note to the order of such assignee in an amount equal to the Commitment assumed by it pursuant to such Assignment and Acceptance and, if the assigning Bank has retained a Commitment hereunder, a new Note to the order of the assigning Bank in an amount equal to the Commitment retained by it hereunder. Such new Note or Notes shall be in an aggregate principal amount equal to the aggregate principal amount of such surrendered Note or Notes, shall be dated the effective date of such Assignment and Acceptance and shall otherwise be in substantially the form of Exhibit L hereto. (g) The Company shall not be liable for any costs or expenses of any Bank in effectuating any participation or assignment under this Section 10.6. (h) The Banks may, in connection with any assignment or participation or proposed assignment or participation pursuant to this Section 10.6, disclose to the assignee or participant or proposed assignee or participant, any information relating to the Company, provided that prior to any such disclosure, each assignee or participant or proposed assignee or participant 57 63 shall agree by executing a confidentiality letter in favor of the Company in form and substance equivalent to the confidentiality agreement described in Section 10.12 hereof. (i) Additional lenders may also become Banks hereunder, with the prior written consent of the Company and the Agent, by executing an Assumption Agreement substantially in the form of Exhibit M hereto, provided that without the prior written consent of the Majority Banks, the aggregate Commitments of all Banks may not exceed $110,000,000. Any Bank, subject to the prior written approval of the Majority Banks, the Agent and the Company and subject to being paid in full or all outstanding liabilities owing to such Bank, may be terminated as a Bank hereunder and upon such termination the Company shall have the option to select a bank to replace such terminating bank and to assume the rights and obligations of such terminated Bank hereunder, provided that such replacement bank is acceptable to the Agent and executes an Assumption Agreement substantially in the form of Exhibit M hereto. Upon any Bank being added hereto or terminated, a new schedule will be distributed by the Agent to all Banks and the Company showing Commitment amount and the Pro Rata Share of each Bank. 10.7 Governing Law. This Agreement is a contract made under, and the rights and obligations of the parties hereunder shall be governed by and construed in accordance with, the laws of the State of Michigan applicable to contracts made and to be performed entirely within such State. 10.8 Table of Contents and Headings. The table of contents and the headings of the various subdivisions hereof are for the convenience of reference only and shall in no way modify any of the terms or provisions hereof. 10.9 Construction of Certain Provisions. All computations required hereunder and all financial terms used herein shall be made or construed in accordance with GAAP unless such principles are inconsistent with the express requirements of this Agreement. If any provision of this Agreement refers to any action to be taken by any Person, or which such Person is prohibited from taking, such provision shall be applicable whether such action is taken directly or indirectly by such Person, whether or not expressly specified in such provision. 10.10 Integration and Severability. This Agreement embodies the entire agreement and understanding between the Company and the Banks, and supersedes all prior agreements and understandings, relating to the subject matter hereof. In case any one or more of the obligations of the Company under this Agreement, the Notes or any S/L/C Application shall be invalid, illegal or unenforceable in any jurisdiction, the validity, legality and enforceability of the remaining obligations of the Company shall not in any way be affected or impaired thereby, and such invalidity, illegality or unenforceability in one jurisdiction shall not affect the validity, legality or enforceability of the obligations of the Company under this Agreement, the Notes or any S/L/C Application in any other jurisdiction. 10.11 Interest Rate Limitation. Notwithstanding any provisions of this Agreement, the Notes or any S/L/C Application, in no event shall the amount of interest paid or agreed to be 58 64 paid by the Company exceed an amount computed at the highest rate of interest permissible under applicable law. If, from any circumstances whatsoever, fulfillment of any provision of this Agreement, the Notes or any S/L/C Application at the time performance of such provision shall be due, shall involve exceeding the interest rate limitation validly prescribed by law which a court of competent jurisdiction may deem applicable hereto, then, ipso facto, the obligations to be fulfilled shall be reduced to an amount computed at the highest rate of interest permissible under applicable law, and if for any reason whatsoever the Banks shall ever receive as interest an amount which would be deemed unlawful under such applicable law such interest shall be automatically applied to the payment of principal of the Loans outstanding and other obligations of the Company hereunder (whether or not then due and payable) and not to the payment of interest, or shall be refunded to the Company if such principal has been paid in full. Anything herein to the contrary notwithstanding, the obligations of the Company under this Agreement shall be subject to the limitation that payments of interest shall not be required to the extent that receipt of any such payment by the Banks would be contrary to provisions of law applicable to the Banks which limits the maximum rate of interest which may be charged or collected by the Banks. 10.12 Confidentiality. The Banks and the Agent shall hold all confidential information obtained pursuant to the requirements of this Agreement which has been identified as such by the Company in accordance with their customary procedures for handling confidential information of this nature and in accordance with safe and sound banking practices and in any event may make disclosure to its examiners, affiliates, outside auditors, counsel and other professional advisors in connection with this Agreement or as reasonably required by any bona fide transferee or participant in connection with the contemplated transfer of any Note or participation therein, provided that any Bank shall give notice to the Company of such disclosure to any such transferee or participant, or as required by any governmental agency or representative thereof or pursuant to legal process. Without limiting the foregoing, it is expressly understood that such confidential information shall not include information which, at the time of disclosure is in the public domain or, which after disclosure, becomes part of the public domain or information which any Bank or the Agent had obtained prior to the time of disclosure and identification by the Company under this Section, or information received by any Bank or the Agent from a third party. Nothing in this Section or otherwise shall prohibit any Bank or the Agent from disclosing any confidential information to the other Banks or the Agent or render any of them liable in connection with any such disclosure. 10.13 Counterparts. This Agreement may be executed in any number of counterparts, all of which taken together shall constitute one and the same instrument and any of the parties hereto may execute this Agreement by signing any such counterpart. 10.14 Independence of Covenants. All covenants hereunder shall be given independent effect so that if a particular action or condition is not permitted by any such covenant, the fact that it would be permitted by an exception to, or would be otherwise within the limitations of, another covenant shall not avoid the occurrence of an Event of Default or any event or condition 59 65 which with notice or lapse of time, or both, could become such an Event of Default if such action is taken or such condition exists. 10.15 Jury Trial Waiver. The Agent, the Banks and the Company, after consulting or having had the opportunity to consult with counsel, knowingly, voluntarily and intentionally waive any right any of them may have to a trial by jury in any litigation based upon or arising out of this Agreement or any related instrument or agreement or any of the transactions contemplated by this Agreement or any course of conduct, dealing, statements (whether oral or written) or actions of any of them. Neither the Agent, the Banks nor the Company shall seek to consolidate, by counterclaim or otherwise, any such action in which a jury trial has been waived with any other action in which a jury trial cannot be or has not been waived. These provisions shall not be deemed to have been modified in any respect or relinquished by either the Agent and the Banks or the Company except by a written instrument executed by all of them. IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be duly executed and delivered as of this 1st day of November, 1993, which shall be the Effective Date of this Agreement, notwithstanding the day and year first above written.
