The pro forma computation of ratio of earnings to fixed charges 
gives effect to the Merger to be accounted for as a pooling of interests. The
financial information on the preceding pages presents (i) the historical
computation of ratio of earnings to fixed charges of both the Corporation and
Midlantic, for the six months ended June 30, 1995 and for each of the five years
in the period ended December 31, 1994 and (ii) the computation of ratio of
earnings to fixed charges, giving effect to the Merger as if it had occurred at
the beginning of the earliest period presented.

During 1995 and 1994, the Corporation and Midlantic completed or have pending,
various other acquisitions which individually and in the aggregate are not
"significant subsidiaries" in relation to the Corporation. Accordingly, pro 
forma financial information with respect to those acquisitions is not included
herein.

The pro forma consolidated financial information is intended for informational
