NOTES:

(1)  For 2001, ROE (and pro-forma EPS) excluded goodwill amortization and
     restructuring charges. For 2002, EPS targets are on an "as reported" (all
     inclusive) basis.

(2)  For 2002, cash flow is defined as cash from operations; less regulated and
     non-regulated capital expenditures and dividends; plus MCN out-of-region
     asset sales.

(3)  For 2002 approximately 90% of DTE's customers will be included in this
     measurement (both electric and gas, residential, small businesses and some
     large businesses).

(4)  For 2002 Diversity Placements will be measured across the entire DTE
     enterprise.

(5)  To determine final payouts, the actual results will be interpolated between
     the Threshold and Target, and between the Target and Maximum for each of
     the four measures.<PAGE>
