-- The corporation expects electric segment earnings in the range of

$19.0 million to $24.0 million in 2007, which is consistent with 2007

prior guidance. A major maintenance shutdown of Big Stone Plant planned

for the third quarter of 2007 was rescheduled for the fourth quarter of

2007, resulting in a shift in anticipated expenditures and plant

availability between the quarters.

-- The corporation expects the plastics segment's earnings performance to

be in the range of $6.0 million to $8.5 million, which is consistent

with 2007 prior guidance.

-- Continued enhancements in productivity and capacity utilization and

strong backlogs are expected to result in increased net income in the

manufacturing segment in 2007.

-- The corporation expects flat to slightly declining earnings in the

health services segment in 2007 primarily due to lower sales at the

diagnostic imaging services company. This is a change from prior

guidance of moderate net income growth from this segment in 2007.

-- The corporation expects its food ingredient processing business to

generate net income in the range of $3.0 million to $4.5 million in

2007, a change from prior guidance of $2.5 million to $4.5 million.

-- The other business operations segment is expected to have lower

earnings in 2007 compared with 2006 due to an expected return to more

normal corporate cost levels. The construction companies are expected

to have a strong 2007 given performance in the first nine months of

2007 and current backlogs.
