Notes:
(1)  Earnings and fixed charges are defined and computed in accordance with
     instructions for Item 3 of Form S-3.
(2)  This amount is estimated to be a reasonable approximation of the interest
     portion of rentals.
MichCon is a guarantor of certain other debt.  Fixed charges related to such
debt are deemed to be immaterial and therefore have been excluded from the
above ratios.
