                      UNION PACIFIC BRINGS LITIGATION TO
                       INVALIDATE SANTA FE POISON PILL
                    - - - - - - - - - - - - - - - - - - -

          BETHLEHEM, PA, JANUARY 18, 1995 -- Union Pacific
          Corporation (NYSE: UNP) announced today that it is
          amending its litigation against Santa Fe Pacific
          Corporation (NYSE: SFX), Burlington Northern Inc. (NYSE:
          BNI) and Santa Fe's Board of Directors in the Delaware
          Chancery Court in connection with its previously
          announced all-cash tender offer for Santa Fe shares.

               The litigation seeks, among other things, to
          invalidate the Santa Fe "poison pill" rights plan, compel
          Santa Fe to adopt a fair and equal process for
          considering competing Union Pacific and Burlington
          Northern bids, and invalidate the $60 million "lock up"
          termination fee and expense reimbursement provisions
          granted by Santa Fe to Burlington Northern.

               Union Pacific's amended complaint asserts, among
          other things, that Santa Fe and its Board of Directors
          have breached their fiduciary duties by entering into a
          merger agreement with Burlington Northern in violation of
          their obligation to seek the best proposal for Santa Fe
          shareholders, by failing to consider competing proposals
          on a fair and equal basis, by adopting a discriminatory
          "poison pill" rights plan and granting "lock up" payments
          to Burlington Northern.
