        BLACKHAWK BANCORP, INC. COMPLETES THE ACQUISITION OF DUNC CORP.

BELOIT, WISCONSIN and CAPRON, ILLINOIS--September 30, 2003--Blackhawk Bancorp,
Inc. ("Blackhawk") and DunC Corp. ("DunC") announced today that the two
organizations have completed the acquisition of DunC by Blackhawk. The
shareholders of DunC overwhelmingly approved the acquisition of DunC by
Blackhawk at a special meeting held on September 18, 2003. Blackhawk owns
Blackhawk State Bank with nine offices located in Beloit, Wisconsin (3) and
Rockford, Belvidere (2), Roscoe, Oregon and Rochelle, Illinois. DunC owns First
Bank bc with offices in Machesney Park, Belvidere, Rockford and Capron,
Illinois. The acquisition is effective September 30, 2003.

Under terms of the merger each share of DunC will be exchanged for $1,523.18 in
cash.

Effective immediately, current customers of First Bank bc will now have the
advantage of banking at nine additional branch locations, seven new ATM's, in
addition to full trust and investment services, online banking and banking seven
days a week.

Current customers of Blackhawk State Bank will be able to bank at three new
branches in Machesney Park, Belvidere and Capron, three new ATM locations and
Sunday banking at Machesney Park.

"This affiliation is a natural fit to our existing branch network and our
strategies for growth," said R. Richard Bastian III, President and Chief
Executive Officer of Blackhawk Bancorp, Inc.

"It underscores our commitment to be the premier community bank in the state-
line area.  Expanding our locations is a natural extension of fulfilling the
financial needs of people on both sides of the border," he said.

"We are the only bank along the I-90 corridor between Beloit and Belvidere with
branches in every major community."

After completion of this merger, Blackhawk will rank second in deposit balances
in fast growing Boone County and in Beloit.

"Our intention is to be the community bank of choice because we not only offer
top notch service, but convenience in the form of Sunday banking and branches
along major roads to accommodate cross border commuting, shopping and people's
lifestyles," continued Bastian.

"The acquisition will help us create an even stronger financial services company
with a broader array of services and locations, enhanced financial efficiencies,
new technologies and new products," he said.

"Blackhawk is an ideal partner for First Bank" added Blachford. "Our customers
will continue to receive the personal attention that only a community bank can
provide.  In addition, our customers will have the added benefit of access to a
broader line of products and services, including internet banking, cash
management and trust services.

"We chose Blackhawk because of its focus on community banking and its commitment
to maintaining close customer relationships," said Blachford.
