SECURITIZATION
================================================================================

- - DTE Energy is issuing Securitization Bonds to fully, and immediately, recover
  100% of stranded costs.

- - On Friday, March 2, Detroit Edison priced $1.75 billion of securitization
  bonds with an average interest rate of 6.1%. Settlement date is set for March
  9, 2001.

- - Between the passage of legislation and the issuing of bonds, DTE Energy
  achieved the shortest time interval of any utility nationwide.

- - Securitization proceeds will be used to strengthen DTE Energy's balance sheet
  and increase shareholder value. Proceeds will be used to retire existing debt
  ($1.3 billion) and repurchase outstanding shares ($0.4 billion).

                                                                               7
