(1) Earnings and fixed charges are defined and computed in accordance with Item
    503 of Regulation S-K.

(2) This amount represents the aggregate of (a) the pre-tax income (loss) of MCN
    Energy Enterprises Inc., (MCNEE) and its majority-owned subsidiaries, (b)
    MCNEE's share of pre-tax income of its 50% owned companies and (c) any
    income actually received from less than 50% owned companies.

(3) Fixed charges added to earnings are adjusted to exclude interest capitalized
    during the period.

(4) For the twelve-month period ended December 31, 1999, MCNEE recorded several
    unusual charges, consisting of property write-downs, investment and contract
    losses, loss on sale of properties and merger costs totaling $160,282,000
    pre-tax ($104,184,000 net of taxes).

    unusual charges, consisting of property write-downs, investment loss and
    restructuring charges, totaling $564,984,000 pre-tax ($367,239,000 net of
    taxes).

    adequate to cover fixed charges.  The amount of the coverage deficiency was
    $218,790,000. The amount of the coverage deficiency excluding unusual
    charges would have been $58,508,000.

    adequate to cover fixed charges. The amount of the coverage deficiency was
