(i) no Interest Period shall extend beyond the Revolving Credit Maturity Date; and

13

(ii) any Interest Period which would otherwise end on a day which is not a Business Day shall be extended to the next succeeding Business Day unless the next succeeding Business Day falls in another calendar month, in which case, such Interest Period shall end on the immediately preceding Business Day and when an Interest Period begins on a day which has no numerically corresponding day in the calendar month during which such Interest Period is to end, it shall end on the last Business Day of such calendar month.

The Company shall elect the initial Interest Period applicable to a Eurodollar-based Advance by its Request for Advance given to the Bank pursuant to Section 2.3 or by its notice of conversion given to the Bank pursuant to Section 3.3, as the case may be. Provided that no Event of Default shall have occurred and be continuing, the Company may elect to continue an Advance as a Eurodollar-based Advance by giving irrevocable written, telephonic or telegraphic notice thereof to the Bank, before 11:00 a.m. on the last day of the then current Interest Period applicable to such Eurodollar-based Advance, specifying the duration of the succeeding Interest Period therefor. If the Bank does not receive timely notice of the election and the Interest Period elected by the Company, the Company shall be deemed to have elected to convert such Eurodollar-based Advance to a Prime-based Advance at the end of the then current Interest Period. No more than seven (7) Interest Periods shall be in effect at any one time with respect to the Revolving Credit Note.

3.3 Provided that no Event of Default shall have occurred and be continuing, the Company may, on any Business Day, convert any outstanding Advance into an Advance of another type in the same aggregate principal amount, provided that any conversion of a Eurodollar-based Advance shall be made only on the last Business Day of the then current Interest Period applicable to such Advance. If the Company desires to convert an Advance, it shall give the Bank written or telephonic notice, specifying the date of such conversion, the Advances to be converted, the type of Advance elected and, if the conversion is into a Eurodollar-based Advance, the duration of the first Interest Period therefor, which notice shall be given not later than 11:00 a.m. on the applicable date of conversion.

4. SPECIAL PROVISIONS, CHANGES IN CIRCUMSTANCES AND YIELD PROTECTION.

4.1 If Company makes any payment of principal with respect to any Eurodollar-based Advance on any day other than the last day of the Interest Period applicable thereto (whether voluntarily, by acceleration, or otherwise), or if Company fails to borrow any Eurodollar-based Advance after notice has been given by Company to Bank in accordance with the terms hereof requesting such Advance, or if Company fails to make any payment of principal or interest when due in respect of a Eurodollar-based Advance, Company shall reimburse Bank on demand for any resulting loss, cost or expense incurred by Bank as a result thereof, including, without limitation, any such loss, cost or expense incurred in obtaining, liquidating, employing or redeploying deposits from third parties, whether or not Bank shall have funded or committed to

14

fund such Advance. Such amount payable by Company to Bank may include, without limitation, an amount equal to the excess, if any, of (a) the amount of interest which would have accrued on the amount so prepaid, or not so borrowed, refunded or converted, for the period from the date of such prepayment or of such failure to borrow, refund or convert, through the last day of the relevant Interest Period, at the applicable rate of interest for said Advance(s) provided under this Agreement, over (b) the amount of interest (as reasonably determined by Bank) which would have accrued to Bank on such amount by placing such amount on deposit for a comparable period with leading banks in the interbank eurodollar market. Calculation of any amounts payable to Bank under this paragraph shall be made as though Bank shall have actually funded or committed to fund the relevant Eurodollar-based Advance through the purchase of an underlying deposit in an amount equal to the amount of such Advance and having a maturity comparable to the relevant Interest Period; provided, however, that Bank may fund any Eurodollar-based Advance in any manner it deems fit and the foregoing assumptions shall be utilized only for the purpose of the calculation of amounts payable under this paragraph. Upon the written request of Company, Bank shall deliver to Company a certificate setting forth the basis for determining such losses, costs and expenses, which certificate shall be conclusively presumed correct, absent manifest error.

4.2 For any Interest Period for which the Applicable Interest Rate is the Eurodollar-based Rate, if Bank shall designate a Eurodollar Lending Office which maintains books separate from those of the rest of Bank, Bank shall have the option of maintaining and carrying the relevant Advance on the books of such Eurodollar Lending Office.

4.3 If with respect to any Interest Period Bank reasonably determines that, by reason of circumstances affecting the foreign exchange and interbank markets generally, deposits in Eurodollars in the applicable amounts are not being offered to the Bank for such Interest Period, then Bank shall forthwith give notice thereof to the Company. Thereafter, until Bank notifies Company that such circumstances no longer exist, the obligation of Bank to make Eurodollar-based Advances for such Interest Period, and the right of Company to convert an Advance to or refund an Advance as a Eurodollar-based Advance for such Interest Period shall be suspended.

4.4 If, after the date hereof, the introduction or implementation of, or any change in, any applicable law, rule or regulation or in the interpretation or administration thereof by any governmental authority charged with the interpretation or administration thereof, or compliance by Bank (or its Eurodollar Lending Office) with any request or directive (whether or not having the force of law) of any such authority, shall make it unlawful or impossible for the Bank (or its Eurodollar Lending Office) to honor its obligations hereunder to make or maintain any Advance with interest at the Eurodollar-based Rate, Bank shall forthwith give notice thereof to Company. Thereafter (a) the obligations of Bank to make Eurodollar-based Advances and the right of Company to convert an Advance or refund an Advance as a Eurodollar-based Advance shall be suspended and thereafter Company may select as Applicable Interest Rates only those which remain available, and (b) if Bank may not lawfully continue to maintain an Advance to the end of the then current Interest Period applicable thereto, the Prime-based Rate shall be the Applicable Interest Rate for the remainder of such Interest Period.

4.5 If the adoption or implementation after the date hereof, or any change after the date hereof in, any applicable law, rule or regulation of any governmental authority, central bank

15

or comparable agency charged with the interpretation or administration thereof, or compliance by Bank (or its Eurodollar Lending Office) with any request or directive (whether or not having the force of law) made by any such authority, central bank or comparable agency after the date hereof:

(a) shall subject Bank (or its Eurodollar Lending Office) to any tax, duty or other charge with respect to any Advance or any Note or shall change the basis of taxation of payments to Bank (or its Eurodollar Lending Office) of the principal of or interest on any Advance or the Note or any other amounts due under this Agreement in respect thereof (except for changes in the rate of tax on the overall net income of Bank or its Eurodollar Lending Office imposed by any jurisdiction in which Bank is organized or engaged in business); or

(b) shall impose, modify or deem applicable any reserve (including, without limitation, any imposed by the Board of Governors of the Federal Reserve System), special deposit or similar requirement against assets of, deposits with or for the account of, or credit extended by Bank (or its Eurodollar Lending Office) or shall impose on Bank (or its Eurodollar Lending Office) or the foreign exchange and interbank markets any other condition affecting any Advance or the Note;

and the result of any of the foregoing is to increase the costs to Bank of maintaining any part of the indebtedness hereunder or to reduce the amount of any sum received or receivable by Bank under this Agreement or under the Note, by an amount deemed by the Bank to be material, then Bank shall promptly notify Company of such fact and demand compensation therefor and, within fifteen days after demand by Bank, Company agrees to pay to Bank such additional amount or amounts as will compensate Bank for such increased cost or reduction. Bank will promptly notify Company of any event of which it has knowledge which will entitle Bank to compensation pursuant to this Section. A certificate of Bank setting forth the basis for determining such additional amount or amounts necessary to compensate Bank shall be conclusively presumed to be correct save for manifest error. Bank agrees that, as promptly as practical after it becomes aware of the occurrence of any event or the existence of a condition that will cause Bank to be entitled to compensation under this Section, it will, to the extent not inconsistent with Bank’s internal policies, use reasonable efforts to make, fund or maintain any affected Eurodollar-based Advance through another lending office of Bank if as a result thereof the additional monies which would otherwise be required to be paid in respect of such Eurodollar-based Advance would be materially reduced and if, as determined by Bank, in its reasonable discretion, the making, funding or maintaining of such Eurodollar-based Advance through such other lending office would not materially adversely affect such Advance or Bank. Company shall pay all reasonable expenses incurred by Bank in utilizing another lending office pursuant to this Section.

4.6 In the event that at any time after the date of this Agreement any change in law such as described in Section 4.5, hereof, shall, in the reasonable opinion of Bank require that the credit provided under Section 2 of this Agreement be treated as an asset or otherwise be included for purposes of calculating the appropriate amount of capital to be maintained by Bank or any corporation controlling Bank and such change has or would have the effect of reducing the rate of return on Bank’s or Bank’s parent’s capital or assets as a consequence of the Bank’s

16

obligations hereunder to a level below that which Bank or Bank’s parent would have achieved but for such change, then Bank shall notify Company and demand compensation therefor and, within fifteen days after demand by Bank, Company agrees to pay to Bank such additional amount or amounts as will compensate Bank for such reduction. Bank will promptly notify Company of any event of which it has knowledge which will entitle Bank to compensation pursuant to this Section. A certificate of Bank setting forth the basis for determining such additional amount or amounts necessary to compensate Bank shall be conclusively presumed to be correct save for manifest error.

4.7 A late installment charge equal to five percent (5%) of each late installment under any Note may be charged on any installment payment not received by Bank within ten (10) calendar days after the installment due date but acceptance of this charge shall not waive any default or Event of Default under this Agreement.

4.8 Adjustments to the Applicable Margin, Applicable Fee Percentage and Applicable L/C Commission Rate based on Schedule 1.1 shall be implemented quarterly as follows:

(a) Such adjustments shall be given prospective effect only, effective as of the first day of the first quarter following delivery of the financial statements under Sections 7.1(a) and 7.1(b) hereunder and the covenant compliance report under Section 7.10 hereof, in each case establishing applicability of the appropriate adjustment, in each case with no retroactivity or claw-back. In the event the Company fails timely to deliver such financial statements or the covenant compliance report, then (but without affecting the Event of Default resulting therefrom) from the date delivery of such financial statements and report was required until such financial statements and report are delivered, the margins (including the Applicable Fee Percentage and the Applicable L/C Commission Rate) shall be at the next higher level as compared to the then applicable level (for example if Level 1 was applicable, the margins will move to Level 2) on the Pricing Matrix attached to this Agreement as Schedule 1.1.

(b) From the date of execution of this Agreement until the required date of delivery (or, if earlier, delivery) under Section 7.1(b) of the Company’s financial statements for the fiscal quarter ending September 30, 2005, the margins shall be those set forth under the Level 1 column of the Pricing Matrix attached to this Agreement as Schedule 1.1. Thereafter, all margins shall be based upon the Company’s financial statements and covenant compliance reports, subject to recalculation as provided in subsection 4.8(a) above.

11.6 This Agreement and the Notes have been delivered at Detroit, Michigan, and shall be governed by and construed and enforced in accordance with the laws of the State of Michigan. Whenever possible each provision of this Agreement shall be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Agreement shall be prohibited by or invalid under applicable law, such provision shall be ineffective to the extent of such prohibition or invalidity, without invalidating the remainder of such provision or the remaining provisions of this Agreement.

11.7 No amendments or waiver of any provisions of this Agreement nor consent to any departure by Company therefrom shall in any event be effective unless the same shall be in writing and signed by the Bank, and then such amendment, waiver or consent shall be effective only in the specific instance and for the specific purpose for which given.

11.8 All sums payable by Company to Bank under this Agreement or the other documents contemplated hereby shall be paid directly to Bank at its principal office set forth in Section 11.5 hereof in immediately available United States funds, without set off, deduction or counterclaim. In its sole discretion, Bank may charge any and all deposit or other accounts (including without limit an account evidenced by a certificate of deposit) of Company with Bank for all or a part of any Indebtedness then due; provided, however, that this authorization shall not affect Company’s obligation to pay, when due, any Indebtedness whether or not account balances are sufficient to pay amounts due.

31

11.9 Any payment of the Indebtedness made by mail will be deemed tendered and received only upon actual receipt by Bank at the address designated for such payment, whether or not Bank has authorized payment by mail or any other manner, and shall not be deemed to have been made in a timely manner unless received on the date due for such payment, time being of the essence. Company expressly assumes all risks of loss or liability resulting from non-delivery or delay of delivery of any item of payment transmitted by mail or in any other manner. Acceptance by Bank of any payment in an amount less than the amount then due shall be deemed an acceptance on account only, and the failure to pay the entire amount then due shall be and continue to be an Event of Default, and at any time thereafter and until the entire amount then due has been paid, Bank shall be entitled to exercise any and all rights conferred upon it herein upon the occurrence of an Event of Default. Upon the occurrence and during the continuance of an Event of Default, Company waives the right to direct the application of any and all payments at any time or times hereafter received by Bank from or on behalf of Company. Upon the occurrence and during the continuance of an Event of Default, Company agrees that Bank shall have the continuing exclusive right to apply and to reapply any and all payments received at any time or times hereafter against the Indebtedness in such manner as Bank may deem advisable, notwithstanding any entry by Bank upon any of its books and records. Company expressly agrees that to the extent that Bank receives any payment or benefit and such payment or benefit, or any part thereof, is subsequently invalidated, declared to be fraudulent or preferential, set aside or is required to be repaid to a trustee, receiver, or any other party under any bankruptcy act, state or federal law, common law or equitable cause, then to the extent of such payment or benefit, the Indebtedness or part thereof intended to be satisfied shall be revived and continued in full force and effect as if such payment or benefit had not been made and, further, any such repayment by Bank, to the extent that Bank did not directly receive a corresponding cash payment, shall be added to and be additional Indebtedness payable upon demand by Bank.

11.10 In the event Company’s obligation to pay interest on the principal balance of the Note is or becomes in excess of the maximum interest rate which Company is permitted by law to contract or agree to pay, giving due consideration to the execution date of this Agreement, then, in that event, the rate of interest applicable shall be deemed to be immediately reduced to such maximum rate and all previous payments in excess of such maximum rate shall be deemed to have been payments in reduction of principal and not of interest.

11.11 COMPANY AND BANK ACKNOWLEDGE THAT THE RIGHT TO TRIAL BY JURY IS A CONSTITUTIONAL ONE, BUT THAT IT MAY BE WAIVED. EACH PARTY, AFTER CONSULTING (OR HAVING HAD THE OPPORTUNITY TO CONSULT) WITH COUNSEL OF THEIR CHOICE, KNOWINGLY AND VOLUNTARILY, AND FOR THEIR MUTUAL BENEFIT WAIVES ANY RIGHT TO TRIAL BY JURY IN THE EVENT OF LITIGATION REGARDING THE PERFORMANCE OR ENFORCEMENT OF, OR IN ANY WAY RELATED TO, THIS AGREEMENT OR THE INDEBTEDNESS.

11.12 This Agreement may be terminated by Company at any time by giving Bank not less than five (5) Business Days advanced written notice so long as no Advances, Letters of Credit, unreimbursed drawings under Letters of Credit or other amounts owing from Company to Bank (including Letter of Credit commission amounts and unused fees) are outstanding at the

32

time written notice is given or become outstanding prior to the termination date. Upon the termination of this Agreement, payment by Company to Bank in full of all Indebtedness of Company to Bank and cancellation of all outstanding Letters of Credit, Bank will promptly upon the written request of Company deliver to Company at Company’s cost and expense (a) proper instruments acknowledging the termination of this Agreement, the Security Agreement and any Guaranties (subject to any obligations of Company which expressly survive termination of such Loan Documents) and (b) the original Note marked “cancelled”.

11.13 This Agreement shall become effective upon the execution hereof by Bank and Company.
