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