DETROIT, Feb. 9 /PRNewswire/ -- Comerica Incorporated (NYSE: CMA) today
announced that Imperial Bancorp's net income in 2000 was $41 million, compared
to $87 million in 1999. Comerica completed the acquisition of Imperial
Bancorp on January 29, 2001. The $1.3 billion transaction will be accounted
for as a pooling of interests.

Imperial incurred a $22 million loss in the fourth quarter of 2000,
compared to net income of $38 million in the fourth quarter of 1999. The loss
in the fourth quarter of 2000 was primarily due to an increase in the
provision for credit losses. This increase is in line with Comerica's
expectations.

Imperial's net interest income was $91 million in the fourth quarter of
2000, an increase of $18 million, or 25 percent, from $73 million in the
fourth quarter of 1999. This increase was primarily due to 13 percent growth
in average earning assets as well as a net interest margin of 5.76 percent.

Imperial's noninterest income in the fourth quarter of 2000 was $19
million, down from $75 million in the fourth quarter of 1999. The decrease in
noninterest income was due to a $44 million gain associated with the initial
public offering of Official Payments Corporation (Nasdaq: OPAY) in 1999 and a
significant decline in warrant and equity investment gains. Imperial realized
only $324 thousand in warrant and equity investment gains in the fourth
quarter 2000, compared to $11 million in the same period a year ago. For the
year, warrant and equity investment gains totalled $43 million in 2000 and $23
million in 1999. The Emerging Growth segment continued to grow its warrant
portfolio in the current quarter, ending the year with 779 positions in 552
companies, up substantially from 413 positions in 300 companies at year-end
1999. At December 31, 2000, Imperial's unrealized gain in Emerging Growth
investments and warrants was $3 million.

Imperial's noninterest expenses totaled $82 million in the fourth quarter
of 2000, up 13 percent from $73 million in the fourth quarter of 1999, and
include a one-time $4.5 million accrual for unpaid vacation.

Net charge-offs were $76 million in the fourth quarter 2000. The
allowance for credit losses was $70 million, or 1.70 percent of total loans
and 103 percent of total nonperforming assets at December 31, 2000.
Nonperforming assets totaled $68 million at December 31, 2000 and were in line
with Comerica's expectations.

results will be held at 8:30 a.m. today, February 9, 2001. Interested parties
