CEDAR RAPIDS, IOWA------

         Perpetual Midwest Financial, Inc., parent of Perpetual Savings Bank,
FSB, announced that the company had all time record earnings for the third
quarter ended March 31, 1998 of $628,000. This was a 44.7% increase in
earnings over the $434,000 the company earned in the same quarter last year.
Earnings per share rose 41.7% to $0.34 in the quarter ended March 31, 1998
from $0.24 per share earned in the same quarter last year.

         Net interest income, before provision for loan losses, for the three
months ended March 31, 1998 increased $275,000 to $3.0 million as compared to
the same period last year. Interest income increased $371,000 to $7.7 million
while interest expense increased $96,000 to $4.7 million for the three months
ended March 31, 1998, as compared to the three months ended March 31, 1997.

         Earnings for the nine month period ended March 31, 1998 resulted in
net income of $1.6 million or $0.90 per share of common stock. This compared
to a net loss of $38,000 or ($0.02) per share of common stock for the nine
months ended March 31, 1997 or net income of $853,000 or $0.45 per share of
common stock before a special SAIF assessment.

         The increase in earnings for the first nine months of fiscal 1998
compared to the same period last year was predominantly due to an increase of
$881,000 net interest income, a $273,000 decrease for provision for loan
losses, and a $1.5 million decrease in other expenses predominantly due to the
$1.5 million expense for a special assessment on SAIF-insured institutions in
order to recapitalize the SAIF insurance fund in 1997, offset by a $1.0
million increase in tax provision.
