REVOLVING CREDIT NOTE

Exhibit 10.43

REVOLVING CREDIT NOTE
Prime Referenced Rate

On or before the Maturity Date set forth above, FOR VALUE RECEIVED, the undersigned promise(s) to pay to the order of COMERICA BANK (herein called “Bank”), at any office of the Bank in the State of Michigan, the principal sum of FOURTEEN DOLLARS ($14,000,000.00), or so much of said sum as has been advanced and is then outstanding under this Note, together with interest thereon at the Prime Referenced Rate plus the Applicable Margin.

This Note is a note under which advances, repayments and re-advances may be made from time to time, subject to the terms and conditions of this Note and the Credit Agreement. AT NO TIME SHALL THE BANK BE UNDER ANY OBLIGATION TO MAKE ANY ADVANCES TO THE UNDERSIGNED PURSUANT TO THIS NOTE IF A DEFAULT OR EVENT WITH WHICH THE GIVING OF NOTICE OR PASSAGE OF TIME OR BOTH WOULD CONSTITUTE A DEFAULT SHALL HAVE OCCURRED AND BE COMTINUING.

Accrued and unpaid interest on the unpaid principal balance outstanding hereunder shall be payable monthly, in arrears, on the first Business Day of each month, until maturity (whether as stated herein, by acceleration, or otherwise). Interest accruing hereunder shall be computed on the basis of a year of 360 days, and shall be assessed for the actual number of days elapsed, and in such computation, effect shall be given to any change in the applicable interest rate as a result of any change in the Prime Referenced Rate on the date of each such change.

From and after the occurrence of any Default hereunder, and so long as any such Default remains unremedied or uncured thereafter, the Indebtedness outstanding under this Note shall bear interest at a per annum rate of three percent (3%) above the otherwise applicable interest rate hereunder, which interest shall be payable upon demand. In addition to the foregoing, a late payment charge equal to five percent (5%) of each late payment hereunder may be charged on any payment not received by Bank within ten (10) calendar days after the payment due date therefor, but acceptance of payment of any such charge shall not constitute a waiver of any Default hereunder.

In no event shall the interest payable under this Note at any time exceed the maximum rate permitted by law.

The amount and date of each advance hereunder, its applicable interest rate and the amount and date of any repayment shall be noted on Bank’s records, which records shall be conclusive evidence thereof, absent manifest error; provided, however, any failure by Bank to make any such notation, or any error in any such notation, shall not relieve the undersigned of its/their obligations to repay Bank all amounts payable by the undersigned to Bank under or pursuant to this Note, when due in accordance with the terms hereof.

In the event that any payment under this Note becomes due and payable on any day which is not a Business Day, the due date thereof shall be extended to the next succeeding Business Day, and, to the extent applicable, interest shall continue to accrue and be payable thereon during such extension at the rates set forth in this Note.

All payments to be made by the undersigned to Bank under or pursuant to this Note shall be in immediately available United States funds, without setoff or counterclaim, and in the event that any payments submitted hereunder are in funds not available until collected, said payments shall continue to bear interest until collected.

The undersigned may prepay all or part of the outstanding balance of any Indebtedness hereunder at any time without premium or penalty. Any prepayment hereunder shall also be accompanied by the payment of all accrued and unpaid interest on the amount so prepaid.

If the adoption after the date hereof, or any change after the date hereof in, any applicable law, rule or regulation (whether domestic or foreign) of any governmental authority, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by Bank 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 to any tax, duty or other charge with respect to this Note or any Indebtedness hereunder, or shall change the basis of taxation of payments

to Bank of the principal of or interest under this Note or any other amounts due under this Note in respect thereof (except for changes in the rate of tax on the overall net income of Bank imposed by the jurisdiction in which Bank’s principal executive office is located); 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 shall impose on Bank or the foreign exchange and interbank markets any other condition affecting this Note or the Indebtedness hereunder; and the result of any of the foregoing is to increase the cost 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 Note by an amount deemed by the Bank to be material, then the undersigned shall pay to Bank, within fifteen (15) days of the undersigned’s receipt of written notice from Bank demanding such compensation, such additional amount or amounts as will compensate Bank for such increased cost or reduction. A certificate of Bank, prepared in good faith and in reasonable detail by Bank and submitted by Bank to the undersigned, setting forth the basis for determining such additional amount or amounts necessary to compensate Bank shall be conclusive and binding for all purposes, absent manifest error.

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 Bank, or any interpretation or administration thereof by any governmental authority charged with the interpretation or administration thereof, or compliance by Bank with any guideline, request or directive of any such authority (whether or not having the force of law), including any risk-based capital guidelines, affects or would affect the amount of capital required or expected to be maintained by Bank (or any corporation controlling Bank), and Bank determines that the amount of such capital is increased by or based upon the existence of any obligations of Bank hereunder or the maintaining of any Indebtedness hereunder, and such increase has the effect of reducing the rate of return on Bank’s (or such controlling corporation’s) capital as a consequence of such obligations or the maintaining of such Indebtedness hereunder to a level below that which Bank (or such controlling corporation) could have achieved but for such circumstances (taking into consideration its policies with respect to capital adequacy), then the undersigned shall pay to Bank, within fifteen (15) days of the undersigned’s receipt of written notice from Bank demanding such compensation, additional amounts as are sufficient to compensate Bank (or such controlling corporation) for any increase in the amount of capital and reduced rate of return which Bank reasonably determines to be allocable to the existence of any obligations of the Bank hereunder or to maintaining any Indebtedness hereunder. A certificate of Bank as to the amount of such compensation, prepared in good faith and in reasonable detail by the Bank and submitted by Bank to the undersigned, shall be conclusive and binding for all purposes absent manifest error.

This Note and any other indebtedness and liabilities of any kind of the undersigned (or any of them) to the Bank, and any and all modifications, renewals or extensions of it, whether joint or several, contingent or absolute, now existing or later arising, and however evidenced and whether incurred voluntarily or involuntarily, known or unknown, or originally payable to the Bank or to a third party and subsequently acquired by Bank including, without limitation, any late charges; loan fees or charges; overdraft indebtedness; costs incurred by Bank in establishing, determining, continuing or defending the validity or priority of any security interest, pledg
