                 UNION PACIFIC SAYS BURLINGTON NORTHERN'S
                   ICC FILING IS ENTIRELY WITHOUT MERIT

               Bethlehem, PA, November 17, 1994 -- Union Pacific
     Corporation said today that it believed Burlington Northern
     Inc.'s recent filing with the ICC challenging Union Pacific's
     use of a voting trust in its proposed acquisition of Santa Fe
     Pacific Corporation is entirely without merit.

               Dick Davidson, President of Union Pacific, said,
     "Burlington Northern's claims are inconsistent with decades of
     precedent.  We do not believe the ICC has ever refused to allow
     the use of a voting trust.  Our proposed voting trust is a
     'plain vanilla' document.  It raises none of the controversial
     issues that slowed down the approval of the voting trusts in the
     IC/KCS and SFSP transactions."

               Davidson also noted "Union Pacific's use of a voting
     trust in its acquisition proposal has been repeatedly requested
     by Santa Fe Chairman Robert Krebs.  We continue to believe our
     proposal would provide greater value to Santa Fe's shareholders
     than Burlington Northern's proposed transaction which, by not
     using a voting trust, would require Santa Fe shareholders to
     bear the risk and delay associated with ICC review of their
     merger."

               "Instead of complaining to regulators, as Burlington
     Northern has done," Davidson continued, "Union Pacific will
     continue to seek to work with Santa Fe's Board, through a fair
     bidding process, to reach agreement on a transaction that
     maximizes value and is in the best interests of Santa Fe, Union
     Pacific, our respective shareholders and the shipping public."
