      UNION PACIFIC ANNOUNCES FOURTH QUARTER RESULTS
      Omaha,  NE, January 20, 2000 -- Union Pacific  Corporation  today reported
substantial improvement in its operating performance.  Net income for the fourth
quarter was $242 million,  or $.95 per diluted  share.  The last quarter of 1998
yielded net income of $96  million,  or $.39 per diluted  share,  excluding  the
impact of a one-time charge  associated with revaluation of goodwill at Overnite
Transportation  Company.  Fourth quarter results  included  one-time,  after-tax
merger implementation expenses of $9 million, or $.03 per diluted share in 1999,
and $7 million, or $.03 per diluted share in 1998.
      Union Pacific Corporation,  excluding Overnite,  reported record operating
income of $499 million in the fourth  quarter of 1999,  compared to $256 million
for the same period in 1998. The Railroad's commodity revenues were up 8 percent
to a record  $2.5  billion for the  quarter,  with gains in all six of the major
business groups.  Intermodal and Industrial  Products led the way, with gains of
16 and 12 percent respectively, while Energy set a fourth quarter revenue record
and Autos turned in a best ever  quarter.  Increased  revenues and  productivity
improvements  lowered the operating ratio to 80.8, a reduction of 8.6 percentage
points from the prior year.
      Overnite  Transportation  reported a fourth quarter  operating loss of $13
million  compared  to  operating  income of $16  million  in 1998,  excluding  a
one-time charge for the revaluation of Overnite goodwill. Overnite's revenues in
the quarter remained


essentially flat with the prior year at $259 million. Operating expenses increased 12 percent due to costs associated with a Teamster-led job action. Despite the Teamsters activity, on-time performance improved to 97% for the quarter, the highest all year. For the total year 1999, Union Pacific Corporation reported net income of $810 million compared to a net loss of $86 million in 1998 excluding the writedown of Overnite goodwill. "Our fourth quarter results culminate a successful 1999 for Union Pacific and lay a strong foundation as we head into 2000," said Dick Davidson, Chairman and Chief Executive Officer. "In the upcoming year, Union Pacific will stay the course, with unrelenting focus on growing our business by providing high quality, reliable service. We are committed to achieving our vision by translating the tremendous potential of our franchise into tangible results." A fourth quarter and full-year income statement is attached.
