the following amended definition:


 


“ ‘Daily Adjusting
LIBOR Rate’ means, for any day, a per annum interest rate which is equal to the quotient of the following:


 


(1)         for
any day, the per annum rate of interest determined on the basis of the rate for deposits in United States Dollars for a period
equal to one (1) month appearing on Page BBAM of the Bloomberg Financial Markets Information Service at or about 11:00 a.m. (London,
England time) (or as soon thereafter as practical) on such day, or if such day is not a Business Day, on the immediately preceding
Business Day. In the event that such rate does not appear on Page BBAM of the Bloomberg Financial Markets Information Service (or
otherwise on such Service) on any day, the “Daily Adjusting LIBOR Rate” for such day shall be determined by reference
to such other publicly available service for displaying eurodollar rates as may be reasonably selected by Bank, or, in the absence
of such other service, the “Daily Adjusting LIBOR Rate” for such day shall, instead, be determined based upon the average
of the rates at which Bank is offered dollar deposits at or about 11:00 a.m. (Detroit, Michigan time) (or as soon thereafter as
practical), on such day, or if such day is not a Business Day, on the immediately preceding Business Day, in the interbank eurodollar
market in an amount comparable to the principal amount of the Indebtedness outstanding hereunder and for a period equal to one
(1) month;


 


divided by


 


(2)         1.00
minus the maximum rate (expressed as a decimal) on such day at which Bank is required to maintain reserves on “Euro-currency
Liabilities” as defined in and pursuant to Regulation D of the Board of Governors of the Federal Reserve System or, if such
regulation or definition is modified, and as long as Bank is required to maintain reserves against a category of liabilities which
includes eurodollar deposits or includes a category of assets which includes eurodollar loans, the rate at which such reserves
are required to be maintained on such category;


 


provided,  however,
and notwithstanding anything to the contrary set forth in this Addendum, if at any time the Daily Adjusting LIBOR Rate determined
as provided above would be less than zero percent (0%), then the Daily Adjusting LIBOR Rate shall be deemed to be zero percent
(0%) per annum for all purposes of this Addendum. Each calculation by Bank of the Daily Adjusting LIBOR Rate shall be conclusive
and binding for all purposes, absent manifest error.”
