                     UNION PACIFIC UPDATES EARNINGS OUTLOOK
                   HIGH FUEL PRICES IMPACTING BUSINESS RESULTS


         OMAHA, NEB., MARCH 24, 2003 - Union Pacific Corporation (NYSE: UNP)
today announced that its first quarter diluted earnings per share from
continuing operations is expected to be in the $0.58 to $0.60 range. This
compares to $0.86 in the first quarter of 2002 and is lower than the Company's
initial target estimate for the quarter. During the quarter, war fears
dramatically increased the Company's fuel cost and contributed to a recent
softening in economic demand. In addition, winter storms have had an impact on
financial results.

         "Average diesel fuel prices for the quarter are almost $0.40 per gallon
more than we paid a year ago. Operating costs for the entire transportation
industry have been inflated by fuel prices that reached all-time highs during
the quarter," said Dick Davidson, chairman and chief executive officer. "In
addition, while first quarter revenues started out fairly strong, as war
tensions increased and crude oil prices rose, we saw a weakening in some
customer shipments. As a result, we have not experienced the growth we'd
expected, particularly in March, which is typically the strongest month of the
quarter."

2003 FIRST QUARTER IMPACTS

         Key factors affecting the quarterly earnings results include:

         o        Rising diesel fuel prices will add approximately $130 million
                  to operating expenses, or costing nearly $0.30 per diluted
                  share from 2002 to 2003.

         o        Coal inventory adjustments at utility plants and the
                  operational impact of a severe March storm will result in
                  lower than expected Energy revenues.

         o        Softening demand toward the end of the quarter has resulted in
                  lower than expected growth in our domestic intermodal and
                  chemicals businesses.

         o        Severance costs will total $0.04 per diluted share in the
                  quarter. Work force level reductions are on plan, but overall
                  costs are less than anticipated due to higher attrition rates
                  and lower severance payments.

         Excluding the effects of increased fuel prices and one-time severance
payments, Union Pacific Railroad's operating margin will likely match, or be
slightly better than last year's rate.

FAS 143

         In the first quarter, the Company will also report a cumulative effect
of a change in accounting principle that will add approximately $250 to $300
million after tax to Union Pacific's first quarter net income. This change
results from the adoption of FAS 143 (Accounting for Asset Retirement
Obligations). This new standard is being adopted by all rail transportation
companies and changes the way the rail industry accounts for track structure
removal costs. This change will have no impact on liquidity.

2003 OUTLOOK

         "It appears that high fuel prices and economic weakness in the first
half of the year will challenge the Company's ability to reach our 2003 goal of
5 to 10 percent earnings growth over 2002 core earnings* of $4.30 per diluted
share," said Davidson. "In the face of these head winds, however, the men and
women of Union Pacific remain dedicated to achieving continued productivity
gains, improved service reliability and increased customer satisfaction.

         "Looking ahead, I'm hopeful that a quick and positive outcome to the
war in Iraq will restore consumer confidence, strengthen the economy and
continue to drive fuel prices lower, thus helping to drive a strong second half
performance for the Company. "
