               UNION PACIFIC CORPORATION AND SUBSIDIARY COMPANIES

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

                                   (Unaudited)

1.   Responsibilities  for  Financial  Statements - The  consolidated  financial
     statements are unaudited and reflect all  adjustments  (consisting  only of
     normal and recurring  adjustments)  that are, in the opinion of management,
     necessary for a fair  presentation of the financial  position and operating
     results for the interim  periods  presented.  The Statement of Consolidated
     Financial  Position at December 31, 1998 is derived from audited  financial
     statements.  The  consolidated  financial  statements  should  be  read  in
     conjunction  with the consolidated  financial  statements and notes thereto
     contained in the Union Pacific  Corporation (the Corporation or UPC) Annual
     Report to  Shareholders  incorporated  by  reference  in the  Corporation's
     Annual  Report on Form  10-K for the year  ended  December  31,  1998.  The
     results of operations  for the three and six months ended June 30, 1999 are
     not  necessarily  indicative  of the  results  for the entire  year  ending
     December 31, 1999.  Certain 1998 amounts have been  reclassified to conform
     to the 1999 financial statement presentation.

2.    Segmentation - UPC consists of one reportable segment, rail transportation
      (Rail), and UPC's other product lines (Other Operations). The Rail segment
      includes the  operations of Union Pacific  Railroad  Company  (UPRR),  its
      subsidiaries  and rail  affiliates  (collectively,  the  Railroad).  Other
      Operations  include the  trucking  product line  (Overnite  Transportation
      Company or Overnite),  as well as technology and insurance  product lines,
      corporate  holding  company  operations,  which  largely  support the Rail
      segment, and all appropriate consolidating entries.

         The following tables detail reportable financial  information for UPC's
      Rail  segment  and Other  Operations  for the three  months and six months
      ended June 30, 1999 and 1998, respectively:

      [a]"Other Operations"  includes all product lines that are not significant
         enough to warrant reportable segment classification.

      [b]Included in the "Other"  product line are the results of the  corporate
         holding   company,   Union   Pacific   Technologies,   a  provider   of
         transportation-related   technologies,  Wasatch  Insurance  Limited,  a
         captive insurance  company,  and all necessary  consolidating  entries.
         1998 also includes Skyway Freight Systems, Inc., a provider of contract
         logistics  and  supply  chain  management  services,  which was sold in
         November 1998.

      [c]The Corporation does not have significant intercompany sales activities

      [d]1998 "Other"  includes the  write-down of the investment in Overnite in
         connection with the attempted sale of Overnite (See Note 4).

3.   Acquisitions

     Southern  Pacific  Rail  Corporation   (Southern   Pacific  or  SP)  -  UPC
     consummated  the  acquisition  of Southern  Pacific in September  1996. The
     acquisition   of  SP  was  accounted  for  as  a  purchase  and  was  fully
     consolidated into UPC's results beginning in October 1996.

     Merger  Consolidation  Activities - In connection  with the acquisition and
     continuing integration of UPRR and Southern Pacific's rail operations,  UPC
     is in the  process of  eliminating  5,200  duplicate  positions,  which are
     primarily  employees  involved in activities  other than train,  engine and
     yard activities. In addition, UPC is relocating 4,700 positions, merging or
     disposing of redundant  facilities and disposing of certain rail lines. The
     Corporation is also canceling uneconomical and duplicative SP contracts.

         To date, UPC has severed 2,500  employees and relocated 4,100 employees
     due to merger  implementation  activities.  UPC  recognized  a $958 million
     pre-tax merger  liability as part of the SP purchase  price  allocation for
     costs associated with SP's portion of these  activities.  In addition,  the
     Railroad expects to incur $130 million in pre-tax acquisition-related costs
     for  severing or  relocating  UPRR  employees,  disposing  of certain  UPRR
     facilities,  training and  equipment  upgrading  over the  remainder of the
     merger implementation period.  Earnings for the three months ended June 30,
     1999 and 1998 included $8 million and $11 million after-tax,  respectively,
     and for the six months  ended June 30, 1999 and 1998,  included $17 million
     and $29 million after-tax,  respectively, for acquisition-related costs for
     UPRR consolidation activities.


  7

     The  components  of the merger  liability  as of June 30,  1999 were as
     follows:


     --------------------------------------------------------------------------
                                              Original   Cumulative    Current
     Millions of Dollars                       Reserve     Activity    Reserve

                                                               
     Contractual obligations................     $361         $361      $  -
     Severance costs........................      343          261        82
     Contract cancellation fees and
       facility and line closure costs......      145          125        20
     Relocation costs.......................      109           84        25
     --------------------------------------------------------------------------
     Total..................................     $958         $831      $127
     --------------------------------------------------------------------------



     Merger  Liabilities - Merger liability activity reflected cash payments for
     merger   consolidation   activities  and  reclassification  of  contractual
     obligations  from  merger  liabilities  to  contractual  liabilities.   The
     Corporation  expects that the remaining  merger  payments will be made over
     the course of the next three years as labor  negotiations are completed and
     implemented, and related merger consolidation activities are finalized.

     Mexican Railway Concession - During 1997, UPRR and a consortium of partners
     were  granted  a  50-year  concession  to  operate  the  Pacific-North  and
     Chihuahua  Pacific  lines in  Mexico  and a 25%  stake in the  Mexico  City
     Terminal  Company  at a  price  of $525  million.  The  consortium  assumed
     operational  control  of both  lines  in  1998.  In  March  1999,  the UPRR
     purchased an additional 13% ownership  interest for $87 million from one of
     its partners.  The UPRR now holds a 26% ownership  share in the consortium.
     The investment is accounted for under the equity method.

4.   Attempted  Sale of  Overnite  - In May  1998,  the  Corporation's  Board of
     Directors  approved a formal plan to divest  UPC's  investment  in Overnite
     through an initial  public  offering  (IPO).  UPC  recorded a $262  million
     after-tax loss from  discontinued  operations in the second quarter of 1998
     to provide  for the  expected  loss from the sale of  Overnite.  During the
     fourth  quarter of 1998,  it became  apparent  that  because  of  continued
     weakness in the IPO market, a successful divestiture of Overnite within the
     one year time limit prescribed by generally accepted accounting  principles
     was no longer  reasonably  assured.  As a result,  in the fourth quarter of
     1998  the  Corporation   reclassified   Overnite's  results  to  continuing
     operations and reversed the $262 million loss from discontinued operations.
     Overnite's   operating   results  have  been   reclassified  to  continuing
     operations for all periods.  Additionally,  as discussed in the 1998 Annual
     Report,  the Corporation  changed its method of valuing goodwill during the
     fourth  quarter  of 1998.  In  connection  with this  change in  accounting
     policy, $547 million of goodwill related to the acquisition of Overnite was
     written off during the fourth quarter of 1998.

5.   Financial Instruments - The Corporation and its subsidiaries use derivative
     financial  instruments  in limited  instances  and for other  than  trading
     purposes to manage risk as it relates to fuel  prices and  interest  rates.
     Where the  Corporation  has fixed interest rates or fuel prices through the
     use of swaps,  futures or forward contracts,  the Corporation has mitigated
     the downside risk of adverse price and rate movements; however, it has also
     limited future gains from favorable movements.

     Credit  Risk - The total  credit  risk  associated  with the  Corporation's
     counterparties  was  $96  million  at  June  30,  1999.  UPC  has  received
     collateral  relating to its hedging  activity  where the  concentration  of
     credit risk was substantial.

  9

     Valuation  -  The  fair  market  values  of  the  Corporation's  derivative
     financial  instrument positions at June 30, 1999 and December 31, 1998 were
     determined  based upon current fair market  values as quoted by  recognized
     dealers or  developed  based upon the  present  value of future  cash flows
     discounted at the applicable U.S. Treasury rate and swap spread.

     The  following is a summary of the Corporation's  financial  instruments at
     June 30, 1999 and December 31, 1998:

     Sale of  Receivables  - The Railroad  has sold,  on a revolving  basis,  an
     undivided  percentage  ownership  interest in a designated pool of accounts
     receivable to third parties  through a  bankruptcy-remote  subsidiary  (the
     Subsidiary).  The Subsidiary is  collateralized  by a $66 million note from
     UPRR. The amount of receivables sold fluctuates based upon the availability
     of the designated pool of receivables and is directly  affected by changing
     business  volumes and credit risks. At June 30, 1999 and December 31, 1998,
     accounts  receivable  are  presented  net of $576 million and $580 million,
     respectively, of receivables sold.

6.   Debt
     Credit  Facilities - The Corporation had $1.2 billion of credit  facilities
     with various banks designated for general  corporate  purposes that expired
     in the first  quarter of 1999.  Because of  improvements  in  earnings  and
     operating cash flows during 1999, the  Corporation no longer  required this
     credit capacity for operational  purposes.  A $2.8 billion credit facility,
     which expires in 2001, remains outstanding.

     Convertible Preferred Securities - Union Pacific Capital Trust (the Trust),
     a statutory  business trust sponsored and wholly owned by the  Corporation,
     has issued $1.5 billion aggregate  liquidation amount of 6-1/4% Convertible
     Preferred  Securities (the CPS).  Each of the CPS has a stated  liquidation
     amount of $50 and is convertible,  at the option of the holder, into shares
     of UPC's common stock, par value $2.50 per share (the Common Stock), at the
     rate of 0.7257 shares of Common Stock for each of the CPS,  equivalent to a
     conversion price of $68.90 per share of Common Stock, subject to adjustment
     under  certain  circumstances.  The CPS accrue  and pay cash  distributions
     quarterly in arrears at the annual rate of 6-1/4% of the stated liquidation
     amount. The Corporation owns all of the common securities of the Trust. The
     proceeds  from the sale of the CPS and the common  securities  of the Trust
     were invested by the Trust in $1.5 billion  aggregate  principal  amount of
     the Corporation's  6-1/4%  Convertible Junior  Subordinated  Debentures due
     April 1, 2028, which debentures represent the sole assets of the Trust.

         For  financial  reporting   purposes,   the  Corporation  has  recorded
     distributions  payable on the CPS as an interest  charge to earnings in the
     statement of consolidated income.

     Significant  New Borrowings - During January 1999, the  Corporation  issued
     $600 million of 6-5/8% debentures with a maturity date of February 1, 2029.
     The proceeds from the issuance of these  debentures were used for repayment
     of debt and other general corporate purposes.

     Shelf Registration Statement - Under currently effective shelf registration
     statements,  the  Corporation may sell, from time to time, up to $1 billion
     in the aggregate of any combination of debt securities, preferred stock, or
     warrants for debt  securities or preferred  stock in one or more offerings.
     The Corporation has no immediate plans to issue equity securities.

     --------------------------------------------------------------------------


9.   Ratio of Earnings to Fixed Charges - The ratio of earnings to fixed charges
     has been computed on a consolidated  basis.  Earnings  represent net income
     (loss) less equity in undistributed earnings of unconsolidated  affiliates,
     plus income taxes and fixed  charges.  Fixed  charges  represent  interest,
     amortization of debt discount and the estimated  interest portion of rental
     charges.  For the three months and six months  ended June 30,  1998,  fixed
     charges exceeded  earnings by approximately  $272 million and $386 million,
     respectively.

10.  Commitments  and  Contingencies  - There are  various  claims and  lawsuits
     pending  against  the  Corporation  and  certain of its  subsidiaries.  The
     Corporation is also subject to Federal,  state and local environmental laws
     and  regulations,  pursuant to which it is currently  participating  in the
     investigation   and  remediation  of  numerous  sites.  In  addition,   the
     Corporation and its subsidiaries also periodically enter into financial and
     other commitments and guarantees in connection with their  businesses,  and
     have  retained  certain  contingent  liabilities  upon the  disposition  of
     formerly owned operations.

     It is not possible at this time for the Corporation to determine  fully the
     effect  of any or  all  unasserted  claims  on its  consolidated  financial
     condition;  however, to the extent possible, where unasserted claims can be
     estimated and where such claims are considered  probable,  the  Corporation
     has recorded a liability. The

 13


     Corporation does not expect that any known lawsuits, claims,  environmental
     costs, commitments or guarantees will have a material adverse effect on its
     consolidated   financial   condition.   Certain   potentially   significant
     contingencies   relating  to  the   Corporation's   and  its  subsidiaries'
     businesses are detailed below:

     Customer  Claims - Certain  customers  have  submitted  claims for  damages
     related to  shipments  delayed by the  Railroad  as a result of  congestion
     problems  during 1997 and 1998,  and certain  customers have filed lawsuits
     seeking relief related to such delays.  The nature of the damages sought by
     claimants includes,  but is not limited to, contractual liquidated damages,
     freight  loss or damage,  alternative  transportation  charges,  additional
     production  costs,  lost  business  and lost  profits.  In  addition,  some
     customers  have asserted that they have the right to cancel  contracts as a
     result of alleged material breaches of such contracts by the Railroad.  The
     Corporation has made no additional provisions for such claims in 1999.

     Shareholder  Lawsuits - UPC and certain of its  directors  and officers are
     defendants in two purported class actions that have been  consolidated into
     one proceeding.  The consolidated  complaint  alleges,  among other things,
     that the  Corporation  violated the Federal  securities  laws by failing to
     disclose   material  facts  and  making  materially  false  and  misleading
     statements   concerning  the  service,   congestion  and  safety   problems
     encountered following the Corporation's  acquisition of Southern Pacific in
     1996.  These lawsuits were filed in late 1997 in the United States District
     Court for the  Northern  District of Texas and seek to recover  unspecified
     amounts of damages.  Management  believes that the  plaintiffs'  claims are
     without merit and intends to defend them  vigorously.  The defendants  have
     moved to dismiss this action,  and the motion has been fully briefed and is
     awaiting a decision by the Court.

         In  addition to the class  action  litigation,  a purported  derivative
     action was filed on behalf of the Corporation and UPRR in September 1998 in
     the District  Court for Tarrant  County,  Texas,  naming as defendants  the
     then-current  and certain former directors of the Corporation and UPRR and,
     as nominal  defendants,  the  Corporation  and UPRR. The derivative  action
     alleges,  among  other  things,  that the named  directors  breached  their
     fiduciary  duties to the Corporation and UPRR by approving and implementing
     the Southern Pacific merger without  informing  themselves of its impact or
     ensuring  that  adequate  controls were put in place and by causing UPC and
     UPRR  to make  misrepresentations  about  UPRR's  service  problems  to the
     financial markets and regulatory  authorities.  The Corporation's  Board of
     Directors  established a special litigation  committee  consisting of three
     independent  directors to review the plaintiff's  allegations and determine
     whether it is in UPC's best  interest to pursue  them.  The  committee  has
     unanimously  concluded that further prosecution of the derivative action on
     behalf of the  Corporation  and UPRR is not in the best  interest of either
     such company.  Accordingly,  the  Corporation  and UPRR have filed a motion
     with the Court to dismiss the derivative  action. The plaintiff has not yet
     responded to the motion. The individual  defendants also believe that these
     claims are without merit and intend to defend them vigorously.

11.  Accounting   Pronouncements  -  In  June  1998,  the  Financial  Accounting
     Standards  Board  issued  Statement  No. 133,  "Accounting  for  Derivative
     Instruments  and  Hedging  Activities"  (FAS  133),  that  would  have been
     effective January 1, 2000. In June 1999, the Financial Accounting Standards
     Board issued Statement No. 137, "Accounting for Derivatives Instruments and
     Hedging  Activities-Deferral  of the Effective  Date of FASB  Statement No.
     133" postponing the effective date for implementing FAS 133 to fiscal years
     beginning after June 15, 2000.  While management is still in the process of
     determining  the  full  effect  FAS  133  will  have  on the  Corporation's
     financial statements,  management has determined that FAS 133 will increase
     the   volatility  of  the   Corporation's   asset,   liability  and  equity
     (comprehensive  income) positions as the change in the fair market value of
     all financial  instruments the  Corporation  uses for fuel or interest rate
     hedging  purposes  will,  upon  adoption  of FAS 133,  be  recorded  in the
     Corporation's Statement of Financial

 14


     Position (See Note 5). In  addition,  to the extent fuel hedges are
     ineffective   due to pricing  differentials  resulting from the geographic
     dispersion of      the  Corporation's   operations,   income  statement
     recognition  of  the      ineffective portion of the hedge position will be
     required. Management does  not  anticipate  that the final  adoption  of
     FAS 133 will have a material impact on UPC's consolidated financial
     statements.

SERVICE ISSUES

The results of operations of Union Pacific  Corporation (the Corporation or UPC)
and its rail segment  (Rail),  which  includes the  operations  of Union Pacific
Railroad Company (UPRR) and its subsidiaries and rail affiliates  (collectively,
the  Railroad),  for the three and six months ended June 30, 1998 were adversely
affected by the  congestion  that began in the third  quarter of 1997.  However,
service recovery  efforts resulted in significant  improvements in operating and
financial  results  beginning in the latter half of 1998 and continuing into the
first half of 1999.

           Three Months Ended June 30, 1999 Compared to June 30, 1998

CONSOLIDATED

Net Income - The  Corporation  reported  net income of $194 million or $0.79 per
basic share and $0.77 per diluted share for the second quarter of 1999, compared
to a net loss of $416 million or $1.69 per basic and diluted share in 1998. This
earnings increase resulted primarily from improved operations and service levels
at UPC's Rail unit, as well as the impact in the second  quarter 1998 results of
a $262 million after-tax loss from discontinued  operations  associated with the
planned  sale of  Overnite  Transportation  Company  (Overnite).  Excluding  the
Overnite  write-down,  the 1998 net loss  from  continuing  operations  was $154
million or $0.63 per basic and diluted share.

Operating  Revenues - Operating  revenues  increased $150 million (6%) to $2,773
million in 1999,  reflecting  increased  volumes and  revenues in all  commodity
lines of the Rail unit, partially offset by the impact of selling Skyway Freight
Systems,  Inc.  (Skyway) in November of 1998.  Skyway  generated  $44 million in
revenue during the second quarter of 1998.

Operating  Expenses - Operating  expenses decreased $430 million (16%) to $2,332
million in 1999.  Salaries,  wages and employee  benefit  costs were $33 million
lower  than  1998,  as  inflation  and volume  growth  were more than  offset by
improved  productivity  at UPC's Rail unit and the impact of the sale of Skyway.
Equipment  and other  rents were $44 million  (12%)  lower than 1998,  resulting
primarily  from  improved  rail cycle  times,  partially  offset by higher  rail
volumes.   Depreciation  expense  was  unchanged  at  $268  million,  reflecting
increased capital spending at the Rail unit offset by lower overall depreciation
rates for rail  equipment and track assets.  Fuel and utilities were $12 million
(6%) lower than 1998,  as lower fuel prices and improved  fuel  efficiency  more
than offset  volume  driven  increases.  Materials and supplies was unchanged at
$146  million.  Casualty  costs  decreased  $23  million  (19%),  as the cost of
rail-related  accident claims  continued to decline.  Other costs decreased $318
million  (57%) to $239  million  in 1999,  reflecting  the  impact in the second
quarter 1998 of a $250 million  expense for the  resolution of customer  claims,
the impact of the sale of Skyway,  lower state and local taxes  (primarily sales
and  property  taxes)  and  increased  benefits  resulting  from the  continuing
integration  of Southern  Pacific  operations.  (See Note 3 to the  Consolidated
Financial Statements.)

 16

Operating  Income - Operating  income  increased $580 million to $441 million in
1999 reflecting both decreased Rail operating expenses and increased revenues.

Non-Operating  Items - Other income decreased $30 million (56%),  reflecting the
impact in the second quarter of 1998 of the sale of the SP headquarters building
and an insurance  recovery for 1997 flood damage.  Interest expense increased $7
million,  the result of  increased  debt  levels  year-over-year.  Income  taxes
increased  $195  million to an $87 million  expense,  reflecting  higher  income
before income taxes, partially offset by settlements related to prior tax years.

RAIL SEGMENT

Net Income - Rail operations  reported net income of $206 million for the second
quarter of 1999 compared to a 1998 net loss of $122 million.  Increased earnings
resulted  primarily  from improved  operations  and service levels and achieving
benefits from the SP merger.

Operating  Revenues - Rail  operating  revenues  increased  $174 million (8%) to
$2,491 million in 1999,  reflecting the Rail unit's continued recovery from 1998
results. Second quarter 1999 results were adversely impacted by an estimated $40
million  reduction in commodity revenue due to the impact on rail traffic of the
implementation of the joint acquisition of Conrail, which primarily affected the
Rail unit's  automotive  and  industrial  traffic,  and the Rail unit's  planned
10-day  maintenance  outage on its central  corridor,  which primarily  affected
energy traffic from the Powder River Basin (PRB). Commodity revenue increased 8%
and carloads increased 6% as all commodity lines showed  improvements over 1998.
Average revenue per car (ARC) improved 2% over 1998 to $1,151.

      The following  table  summarizes the  quarter-over-quarter  change in rail
commodity revenue (CR):

Agricultural - Carloads  increased 11%,  leading to a commodity  revenue gain of
$38 million  (13%) over 1998.  Stronger  exports  and  improved  service  levels
resulted in volume increases in wheat (19%), corn (21%) and beverages (22%). ARC
increased  2%,  primarily the result of increased  long-haul  export moves and a
price increase on wheat movements.

Automotive - Commodity  revenues were up $32 million  (13%),  driven mainly by a
12% increase in  carloadings.  Strong  domestic  production and  improvements in
cycle   times,   partially   offset  by  the  impact  on  rail  traffic  of  the
implementation  of the joint  acquisition  of Conrail,  as well as the  negative
impact  in the  second  quarter  of  1998  of a  strike  against  a  major  auto
manufacturer,  helped to drive a 13% improvement in finished vehicle volumes and
a 10%  improvement  in  parts  volumes.  ARC  increased  1%  per  car  due  to a
combination of product mix and price increases.

 17

Chemicals - Carloadings and commodity revenue  increased 3% over 1998.  Improved
service  levels and recovery in demand drove  increases in plastics,  liquid and
dry  chemicals  and  phosphorous  moves.  These gains were  partially  offset by
declines in soda ash caused by the adverse  impact on demand  resulting from the
Asian  currency  crisis,  lower  sulfur  moves  resulting  from a slow  down  in
production in response to weak demand,  and a decline in demand for  fertilizers
resulting from depressed demand for U.S. farm  commodities.  ARC improved 1% due
to  favorable  product  mix,  reflecting  traffic  improvements  in  longer-haul
plastics and fewer shorter-haul petroleum moves.

Energy - Carloads increased 5%, resulting in a $45 million increase in commodity
revenue.  ARC  improved as a result of an increase in  longer-haul  PRB traffic,
combined  with a 4% increase in tons per car.  Volumes  increased as a result of
longer  trains and more trains per day out of the PRB and improved  service from
Colorado and Utah mines,  offset by a planned 10-day  maintenance  outage in the
central corridor in June 1999.

Industrial - Carloadings increased 3% and commodity revenue increased $8 million
(2%) to $475  million.  Volume  increases  resulted  from  stronger  demand  and
improved cycle times.  Traffic gains occurred in lumber, stone and cement due to
strong  construction  demand.  Recyclables grew due to new business.  Gains were
partially offset by decreased steel loadings due to higher imports of low-priced
foreign  steel,  which  reduced U.S.  production,  and lost volumes from a major
steel producer who filed for  bankruptcy.  ARC declined 1% due to an unfavorable
mix of long- and short-haul business.

Intermodal - Commodity  revenue  increased $46 million (12%) to $426 million and
carloadings  increased  6%.  Results were  positively  affected by strong demand
resulting  from  growth in imports  from Asia,  service  improvements  and a new
premium  service  offering.  These gains were  partially  offset by a decline in
exports  to Asia due to the  Asian  economic  crisis.  ARC  increased  6% due to
positive mix shifts (longer-haul shipments) and demand driven price increases.

Operating  Expenses - Operating  expenses decreased $380 million (16%) to $2,054
million in 1999.  A large  portion  of the  decrease  relates to a $250  million
expense in the second quarter of 1998 for the  resolution  of  customer  claims.
Improvements in service and increased  benefits from the SP merger helped reduce
quarter-over-quarter operating expenses.

Salaries,  wages and employee  benefits - Labor  expenses  were $15 million (2%)
lower than 1998, as higher rail volumes and wage inflation were more than offset
by merger consolidation benefits and productivity improvements.

Equipment  and other rents - Rent  expense  decreased  $40 million  (12%) versus
1998,  due primarily to an improvement  in cycle time,  which  decreased to 12.6
days in 1999  compared to 16.4 days in 1998,  and lower  prices for private tank
cars,  intermodal  equipment  and  other  leased  equipment.  Most of the  price
decrease  was related to a more  favorable  mix of  equipment,  as well as lower
rates resulting from  deregulation of equipment rates.  These  improvements were
partially offset by higher volume as carloads increased 6% quarter-over-quarter.

Depreciation - Depreciation expense grew by $8 million or 3% to $256 million due
to the  Railroad's  capital  spending in the last half of 1998 and first half of
1999,  partially  offset by lower overall  depreciation  rates for equipment and
track assets resulting from the most recent periodic depreciation study required
by the Surface  Transportation  Board of the U.S.  Department of  Transportation
(STB).

 18

Fuel and  utilities - Fuel and  utilities  expenses  were down $11 million or 5%
from 1998,  reflecting lower fuel prices and improved  consumption  rates, which
were  partially  offset by higher  volume.  An 8%  increase in  gross-ton  miles
quarter-over-quarter added volume-related fuel costs of $14 million versus 1998.
Prices were down 7 cents per gallon to 56 cents,  saving $23  million.  The fuel
consumption  rate of 1.39 gallons per thousand  gross-ton miles improved 2% from
last year, lowering fuel costs by another $4 million. The Railroad hedged 69% of
its second quarter fuel  consumption in 1999, which increased fuel costs by less
than a million dollars, or .1 cent per gallon. Expected fuel consumption for the
remaining  six months of 1999 is 64% hedged at an average of 55 cents per gallon
(including taxes, transportation charges and regional pricing spreads).

Materials  and supplies - Materials  and supplies  expense  decreased $1 million
(1%) from 1998. Lower material costs for roadway machines and work equipment and
lower material freight charges more than offset an increase in locomotive repair
material needed for units being removed from storage.

Casualty costs - Casualty costs declined $23 million (21%) from 1998,  primarily
due to the  effect  of  lower  than  expected  settlement  costs.  In  addition,
insurance  costs and costs for repairs on cars from other  railroads  were lower
quarter-over-quarter.

Other costs - Other costs  decreased $298 million (58%) from 1998,  reflecting a
$250 million  expense  recorded in 1998 for the  resolution of customer  claims,
lower state and local taxes  (primarily  sales and property  taxes) and benefits
resulting from the continuing integration of Southern Pacific operations.

Operating  Income - Operating  income  increased $554 million to $437 million in
1999.  Both  periods  included the impact of one-time  merger-related  costs for
severance,  relocation  and  training of  employees  ($13  million  reduction in
operating income in 1999 and $17 million reduction in operating income in 1998).
The operating  ratio for the second quarter of 1999 was 82.5%,  22.5  percentage
points better than 1998's 105.0% operating ratio.

Non-Operating  Items - Other income decreased $33 million (66%),  reflecting the
impact in the second quarter of 1998 of the sale of the SP headquarters building
and an insurance  recovery for 1997 flood damage.  Interest expense increased $8
million,  the result of higher average debt levels.  Income taxes increased $185
million to a $93 million expense,  reflecting higher income before income taxes,
partially offset by settlements related to prior tax years.

OTHER OPERATIONS

Trucking Product Line

Net Income - Trucking earnings increased $1 million to $11 million in the second
quarter  of 1999 from $10  million  in the  second  quarter  of 1998  (excluding
goodwill amortization of $5 million in 1998).

Operating  Revenues -  Trucking  revenues  increased  $11  million  (4%) to $273
million,  primarily  driven by a 3%  increase  in volume and a $2 million  (33%)
increase in Special Services  Division  revenue,  primarily truck load business.
Volume  increases  reflect a new product offering in the northeast United States
and Texas. Rate  improvements from non-contract  customers were partially offset
by a shift in the mix of lower and higher margin customers.

Operating  Expenses -  Operating  expenses  increased  $9  million  (4%) to $258
million  in  1999  compared  to  $249  million  in  1998   (excluding   goodwill
amortization of $5 million in 1998). Salaries,  wages and employee benefit costs

 19

increased $8 million (5%) to $167 million, reflecting wage and benefit inflation
and the addition of a new product  offering in the  northeast  United States and
Texas.  Rent expense  increased  primarily due to costs related to a new premium
service and opening a new facility in Dallas,  Texas.  Fuel costs were unchanged
at $11  million as lower fuel  prices (51 cents in 1999  compared to 52 cents in
1998) offset increased volumes. Fuel hedging increased fuel expense by less than
$1 million in 1999. 40% of estimated remaining 1999 fuel purchases are hedged at
an average of 45 cents per gallon.  Materials and supplies  increased $1 million
(9%) due to increased fleet maintenance  expense resulting from increased volume
and longer average length of haul.  Other costs decreased $1 million (4%) due to
cost control initiatives.

Operating Income - Trucking operations generated operating income of $15 million
for the second quarter of 1999 compared to $13 million for the comparable period
a year  ago  (excluding  goodwill  amortization  of $5  million  in  1998).  The
operating  ratio for trucking  operations  (excluding  goodwill  amortization in
1998) improved to 94.5% in 1999 from 95.1% in 1998.

Other Product Lines

Other operations  include the technology and insurance product lines, as well as
the corporate holding company operations and all necessary consolidating entries
(see  Note 2 to  the  Consolidated  Financial  Statements).  Operating  revenues
declined  $35  million in 1999 due  primarily  to the sale of Skyway in November
1998, offset by a reclassification to operating revenue of commercial technology
revenue  previously  reported in other income.  Operating expenses decreased $54
million  reflecting  the  absence of 1999 costs  associated  with Skyway and the
consolidation  of portions of the Corporate  staff with the Rail unit's staff in
Omaha,  Nebraska.  Operating losses declined $19 million and net losses declined
$14 million compared to 1998, due to the corporate  reorganization  and improved
operations at the Corporation's technology division.

            Six Months Ended June 30, 1999 Compared to June 30, 1998

CONSOLIDATED

Net Income - The  Corporation  reported  net income of $323 million or $1.31 per
basic and diluted share for the first six months of 1999, compared to a net loss
of $478  million or $1.94 per basic and  diluted  share in 1998.  This  earnings
increase resulted primarily from improved operations and service levels at UPC's
Rail unit,  as well as the impact in 1998  results of a $262  million  after-tax
loss from discontinued  operations associated with the planned sale of Overnite.
Excluding the Overnite write-down,  the 1998 net loss from continuing operations
was $216 million or $0.88 per basic and diluted share.

Operating  Revenues - Operating  revenues  increased $304 million (6%) to $5,513
million in 1999,  reflecting  increased  volumes and  revenues in all  commodity
lines of the Rail unit,  partially  offset by the  impact of  selling  Skyway in
November of 1998.  Skyway  generated $89 million in revenue during the first six
months of 1998.

Operating  Expenses - Operating  expenses decreased $605 million (11%) to $4,710
million in 1999.  Salaries,  wages and employee  benefit  costs were $35 million
(2%) lower than 1998,  as inflation  and volume  growth were more than offset by
improved  productivity  at UPC's Rail unit and the impact of the sale of Skyway.
Equipment  and other  rents were $95 million  (13%)  lower than 1998,  resulting
primarily  from  improved  rail  cycle  times  partially  offset by higher  rail
volumes. Depreciation expense increased by $7 million to $538 million reflecting
increased  capital spending at the Rail unit,  partially offset by lower overall
depreciation rates for rail equipment and track assets.  Fuel and utilities were
$44  million  (10%)  lower than 1998,  as lower fuel  prices and  improved  fuel

 20

efficiency more than offset volume driven increases.  Materials and supplies was
unchanged at $290  million.  Casualty  costs  decreased $29 million (12%) as the
cost of rail-related accident claims continued to decline. Other costs decreased
$409  million  (45%) to $496 million in 1999,  reflecting  the impact in 1998 of
expense for the resolution of customer claims,  the impact of the sale of Skyway
and increased  benefits  resulting from the  continuing  integration of Southern
Pacific operations.

Operating  Income - Operating  income  increased $909 million to $803 million in
1999 reflecting both decreased Rail operating expenses and increased revenues.

Non-Operating  Items - Other income decreased $28 million (36%),  reflecting the
impact in the second quarter of 1998 of the sale of the SP headquarters building
and an insurance recovery for 1997 flood damage,  offset by a one-time favorable
contract settlement in the first quarter of 1999. Interest expense increased $32
million,  the result of higher average debt levels.  Income taxes increased $310
million to a $159 million expense, reflecting higher income before income taxes,
partially offset by settlements related to prior tax years.

RAIL SEGMENT

Net Income - Rail  operations  reported  net income of $355  million for the six
months  ended  June  30,  1999  compared  to a 1998  net  loss of $154  million.
Increased  earnings  resulted  primarily  from improved  operations  and service
levels and achieving benefits from the SP merger.

Operating  Revenues - Rail  operating  revenues  increased  $369 million (8%) to
$4,970 million in 1999,  reflecting the Rail unit's continued recovery from 1998
results.  1999  revenues  were  adversely  impacted by an estimated  $40 million
reduction  in  commodity  revenue  due to the  impact  on  rail  traffic  of the
implementation  of the joint  acquisition of Conrail,  which primarily  impacted
automotive  and  industrial   traffic,   and  the  Rail  unit's  planned  10-day
maintenance  outage on its central  corridor,  which  primarily  affected energy
traffic  from the PRB.  Carloadings  for the  first  six  months of 1999 were 6%
higher than 1998. Average revenue per car (ARC) improved 2% over 1998 to $1,162.

Agricultural - Carloads  increased 11%,  leading to a commodity  revenue gain of
$70 million  (12%) over 1998.  Stronger  exports  and  improved  service  levels
resulted in volume increases in wheat, corn and beverages.  ARC remained flat as
longer  hauls in meals and oils and a price  increase  on wheat  movements  were
offset by a shift in corn  movements  to  shorter-haul  Gulf Coast moves  versus
longer-haul Pacific Northwest moves.

Automotive - Commodity  revenue was up $55 million (12%),  driven mainly by a 9%
increase in carloadings.  Strong domestic production,  and improvements in cycle
times,  partially offset by the impact on rail traffic of

 21

the implementation of the joint acquisition of Conrail,  model changeovers and a
plant shut down,  as well as the negative  impact in 1998 of a strike  against a
major auto manufacturer,  resulted in year-over-year  increases in both finished
vehicle and parts  volumes.  ARC  increased 2% per car due to a  combination  of
product mix and price increases.

Chemicals - Carloadings and commodity revenue increased 2% and 3%, respectively,
over 1998.  Improved  service  levels and recovery in demand drove  increases in
plastics,  liquid and dry  chemicals  and  phosphorous  moves.  These gains were
partially  offset by declines in soda ash caused by the adverse impact on demand
resulting from the Asian currency  crisis,  lower sulfur moves  resulting from a
slow down in production in response to weak demand,  and a decline in demand for
fertilizers  resulting  from  depressed  demand for U.S. farm  commodities.  ARC
improved 1% due to favorable  product mix,  reflecting  traffic  improvements in
longer-haul plastics and fewer shorter-haul petroleum and export sulfur moves.

Energy  -  Carloads  increased  6%,  resulting  in a $112  million  increase  in
commodity revenue.  ARC also improved $52 per car (5%) year-over-year  resulting
from changes in traffic mix as longer-haul PRB traffic  increased.  Increases in
the number of PRB trains per day,  tons per car and average  train length helped
to improve 1999 PRB business  versus  1998.  PRB traffic was reduced  during the
Rail unit's planned 10-day  maintenance  outage in June 1999.  Colorado and Utah
volumes also increased due to improved service.

Industrial  -  Carloadings  increased 4% and  commodity  revenue  increased  $24
million (3%) to $924 million. Volume increases resulted from stronger demand and
improved cycle times.  Traffic gains occurred in lumber, stone and cement due to
strong construction demand, and recyclables grew due to new business. Gains were
partially offset by decreased steel loadings due to higher imports of low-priced
foreign  steel,  which  reduced U.S.  production,  and lost volumes from a major
steel producer who filed for  bankruptcy.  ARC declined 1% due to an unfavorable
mix of long- and short-haul business.

Intermodal - Commodity  revenue  increased $73 million (10%) to $814 million and
carloadings  increased  5%.  Results were  affected  positively by strong demand
resulting  from  growth in imports  from Asia,  service  improvements  and a new
premium  service  offering.  These gains were  partially  offset by a decline in
exports  to Asia due to the  Asian  economic  crisis.  ARC  increased  4% due to
positive mix shifts (longer-haul shipments) and demand driven price increases.

Operating  Expenses - Operating  expenses decreased $496 million (11%) to $4,169
million  in 1999.  A large  portion  of the  decrease  relates  to the impact of
expense in 1998 for the resolution of customer  claims.  Improvements in service
and increased  benefits  from the SP merger  helped to drive the  year-over-year
decrease in operating expenses.

Salaries,  wages and employee  benefits - Labor  expenses were $6 million higher
than 1998, a result of higher  volumes and wage  inflation  that were  partially
offset by merger consolidation benefits and productivity improvements.

Equipment  and other rents - Rent  expense  decreased  $85 million  (12%) versus
1998, due primarily to  improvements  in cycle time and lower prices,  partially
offset by higher volume as carloads increased 6% year-over-year.

Depreciation -  Depreciation  expense grew by $20 million or 4% to $514 million,
due to the Railroad's  capital  spending in the last half of 1998 and first half
of 1999,  partially offset by lower overall depreciation rates for

 22


equipment and track assets resulting from the most recent periodic  depreciation
study  required  by the STB.  The  Railroad  spent  over $2  billion  on capital
projects in 1998 and over $800 million on capital  projects during the first six
months of 1999.

Fuel and  utilities - Fuel and  utilities  expenses were down $41 million or 10%
from 1998,  reflecting lower fuel prices and improved  consumption  rates, which
were  partially  offset by higher  volume.  The Railroad  hedged 70% of its fuel
consumption for the first six months of 1999,  which increased fuel costs by $19
million.

Materials and supplies - Materials and supplies expense remained  unchanged from
the first six months of 1998 at $266 million.  Lower  material costs for roadway
machines and work equipment,  lower material  freight charges and higher credits
received for parts  rebuilt,  offset an increase in locomotive  repair  material
needed for units being removed from storage.

Casualty costs - Casualty costs declined $28 million (13%) from 1998,  primarily
due to the  effect  of  lower  than  expected  settlement  costs.  In  addition,
insurance  costs and costs for repairs on cars from other  railroads  were lower
year-over-year.

Other costs - Other costs decreased $368 million (45%) from 1998, reflecting the
impact on 1998 results from expense for the resolution of customer claims, lower
state  and local  taxes  (primarily  sales  and  property  taxes)  and  benefits
resulting from the continuing integration of Southern Pacific operations.

Operating  Income - Operating  income  increased $865 million to $801 million in
1999.  Both  periods  included the impact of one-time  merger-related  costs for
severance,  relocation  and  training of  employees  ($28  million  reduction in
operating income in 1999 and $46 million reduction in operating income in 1998).
The operating ratio for the first six months of 1999 was 83.9%,  17.5 percentage
points better than 1998's 101.4% operating ratio.

Non-Operating  Items - Other income decreased $29 million (42%),  reflecting the
impact in the second quarter of 1998 of the sale of the SP headquarters building
and an insurance recovery for 1997 flood damage.  Interest expense increased $29
million,  the result of higher average debt levels.  Income taxes increased $298
million to a $175 million expense  reflecting higher income before income taxes,
partially offset by settlements related to prior years.

OTHER OPERATIONS

Trucking Product Line

Net  Income -  Trucking  net  income  matched  1998's  results  of $20  million
(excluding goodwill amortization of $10 million in 1998).

Operating  Revenues  -  Trucking  revenues  increased  $7  million  (1%) to $526
million.  Stable volumes combined with a 1% increase in average price to produce
the year-over-year improvement.

Operating  Expenses -  Operating  expenses  increased  $8  million  (2%) to $501
million  in  1999  compared  to  $493  million  in  1998   (excluding   goodwill
amortization of $10 million in 1998). Salaries, wages and employee benefit costs
increased  $12  million  (4%) to  $325  million,  reflecting  wage  and  benefit
inflation  and the addition of a new product  offering in the  northeast  United
States and Texas. Rent expense decreased $2 million (5%) to $40

 23


million,  due to a shift from third  party to internal  transportation  sources.
Fuel costs  decreased $2 million  (8%),  primarily  due to lower fuel prices (47
cents in 1999 compared to 55 cents in 1998). Fuel hedging increased fuel expense
by $1 million in 1999. 40% of estimated remaining 1999 fuel purchases are hedged
at an  average of 45 cents per  gallon.  Materials  and  supplies  increased  $1
million (5%) due to increased fleet maintenance  expense.  Other costs decreased
$1 million (2%) due to cost control initiatives.

Operating Income - Trucking operations generated operating income of $25 million
for the first six months of 1999  compared  to $26  million  for the  comparable
period a year ago (excluding goodwill  amortization of $10 million in 1998). The
operating  ratio for trucking  operations  (excluding  goodwill  amortization in
1998) increased to 95.2% in 1999 from 95.0% in 1998.

Other Product Lines

Other operations  include the technology and insurance product lines, as well as
the corporate holding company operations and all necessary consolidating entries
(see  Note 2 to  the  Consolidated  Financial  Statements).  Operating  revenues
declined  $72  million in 1999 due  primarily  to the sale of Skyway in November
1998, offset by a reclassification to operating revenue of commercial technology
revenue previously  reported in other income.  Operating expenses decreased $107
million  reflecting  the  absence of 1999 costs  associated  with Skyway and the
consolidation  of portions of the Corporate  staff with the Rail unit's staff in
Omaha,  Nebraska.  Operating losses declined $35 million and net losses declined
$20 million  compared to 1998 due to the corporate  reorganization  and improved
operations at the Corporation's technology division.

              CHANGES IN FINANCIAL CONDITION AND OTHER DEVELOPMENTS

Financial  Condition  - During the first six months of 1999,  cash  provided  by
operations  was $978  million,  compared to cash  provided by  operations of $83
million in 1998. This $895 million increase  primarily  reflects higher earnings
at the Corporation's Rail segment resulting from the success of service recovery
efforts  in the first  half of 1999 and the last half of 1998.  Working  capital
improved  due to  continued  emphasis on  receivable  collection  efforts at the
Railroad and the timing of current liability payments.

     Cash used in investing  activities was $841 million in the first six months
of 1999,  compared to a use of $1,223 million in 1998.  This decrease  primarily
reflects lower Rail capital spending,  including merger-related spending, offset
by the  purchase of an  additional  13%  ownership  interest  in the  consortium
operating  the  Pacific-North  and  Chihuahua  Pacific  lines in Mexico  for $87
million (see Note 3 to Consolidated Financial Statements).

     Cash  provided by equity and  financing  activities  was $18 million in the
first six  months of 1999,  compared  to $1.4  billion  provided  in 1998.  Cash
provided in 1999 principally reflects lower net borrowings ($642 million in 1999
compared to $3.4 billion in 1998)  offset by debt repaid  ($528  million in 1999
compared  to $1.8  billion in 1998)  reflecting  the  private  placement  of the
Convertible  Preferred  Securities (the CPS) on April 1, 1998 (see Note 6 to the
Consolidated Financial Statements).

     The ratio of debt to total  capital  employed  (treating  the CPS as a debt
instrument)  was 57.5% at June 30, 1999  compared to 58.0% at December  31, 1998
and 56.9% at June 30, 1998. Including the CPS as an equity instrument, the ratio
of debt to total capital  employed at June 30, 1999 was 49.1%  compared to 49.4%
at December 31, 1998 and 48.4% at June 30, 1998.


 24


     At June 30,  1999,  the  Corporation  had a $2.8  billion  credit  facility
outstanding.  The  facility is  designated  for general  corporate  purposes and
expires in 2001. Under currently  effective shelf registration  statements,  the
Corporation  may sell,  from time to time,  up to $1 billion in the aggregate of
any  combination  of debt  securities,  preferred  stock,  or warrants  for debt
securities or preferred stock in one or more  offerings.  The Corporation has no
immediate plans to issue equity securities.

                                  OTHER MATTERS

Commitments and  Contingencies  - There are various claims and lawsuits  pending
against  the  Corporation  and certain of its  subsidiaries.  In  addition,  the
Corporation and its subsidiaries are subject to various Federal, state and local
environmental  laws and are currently  participating  in the  investigation  and
remediation  of  various  sites.  A  discussion  of  certain  claims,  lawsuits,
guarantees  and  contingencies  is set  forth  in  Note  10 to the  Consolidated
Financial Statements, which is incorporated herein by reference.

Accounting  Pronouncements  - In June 1998, the Financial  Accounting  Standards
Board issued  Statement No. 133,  "Accounting  for  Derivative  Instruments  and
Hedging  Activities" (FAS 133), that would have been effective  January 1, 2000.
In June 1999, the Financial Accounting Standards Board issued Statement No. 137,
"Accounting for Derivatives  Instruments and Hedging  Activities-Deferral of the
Effective  Date of FASB  Statement No. 133"  postponing  the effective  date for
implementing  FAS 133 to fiscal  years  beginning  after  June 15,  2000.  While
management is still in the process of  determining  the full effect FAS 133 will
have on the Corporation's  financial statements,  management has determined that
FAS 133 will increase the volatility of the Corporation's  asset,  liability and
equity  (comprehensive  income) positions as the change in the fair market value
of all  financial  instruments  the  Corporation  uses for fuel or interest rate
hedging   purposes  will,   upon  adoption  of  FAS  133,  be  recorded  in  the
Corporation's  Statement of Financial Position (See Note 5). In addition, to the
extent fuel hedges are ineffective due to pricing  differentials  resulting from
the geographic  dispersion of the  Corporation's  operations,  income  statement
recognition of the  ineffective  portion of the hedge position will be required.
Management  does not  anticipate  that the final adoption of FAS 133 will have a
material impact on UPC's consolidated financial statements.

Year 2000 - The Year 2000  (Y2K)  compliance  project at UPC  includes  software
(internally  developed  and  purchased),  hardware  and  embedded  chips  inside
equipment  and  machinery,   primarily  at  its  Rail  unit.  The  Corporation's
enterprise-wide  project encompasses  computer systems and equipment in multiple
data centers and a telecommunications  network spread over 23 states.  Equipment
containing  embedded  computer  chips  includes  locomotives,   automated  train
switching systems, computer aided train dispatching systems,  signaling systems,
computerized  fueling  stations,  weigh-in-motion  scales,  cranes,  lifts,  PBX
systems,  elevators, and computerized monitoring systems throughout UPC. The Y2K
project   started  with  research  in  1994  and  an  impact   analysis  of  the
Corporation's  mainframe  COBOL systems in 1995. The Y2K project has been a high
priority since then.

     UPC's Y2K Project is divided into five major initiatives as follows:

Mainframe  Systems - These systems have been converted,  tested and deemed to be
Y2K compliant as of December 31, 1998.  Periodic  audits are planned during 1999
to ensure these systems remain Y2K compliant.

Client Server Systems - All critical  client server systems have been converted,
tested, and deemed to be Y2K compliant as of December 31, 1998. The non-critical
client server systems were deemed to be Y2K compliant as of June 30, 1999.


 25


User Department  Developed Systems - These systems consist of both mainframe and
PC-based systems developed by internal user departments. All of the systems were
deemed to be Y2K compliant as of June 30, 1999.

Vendor Supplied and Embedded Systems - These systems consist of  vendor-supplied
software,  desktop,  mainframe  and server  hardware,  databases  and  operating
systems,  as well as equipment and machinery with embedded systems.  One hundred
percent of the  identified  critical  suppliers of these systems have  indicated
that they have a  comprehensive  Year 2000 plan.  To help assure  safety and Y2K
compliance,  UPC is testing selected  critical  software,  hardware and embedded
systems,  even if the vendor has already certified the product.  The Corporation
is  sharing  information  on the  compliance  and  testing  of  safety  critical
components  common to the industry with the  cooperation  of the  Association of
American Railroads (AAR).

Electronic Commerce Systems - These systems consist of all electronic  exchanges
of  information   with  customers,   vendors,   other  railroads  and  financial
institutions.  The railroad  industry has agreed on a standard  4-digit year for
all  electronic  data  interchange  (EDI).  The Rail unit can now  transmit  and
receive the new EDI standard that involves a 4-digit year.  The  Corporation  is
conducting  additional  Y2K testing with  customers and trading  partners  using
current and older versions of EDI transactions in 1999.

     In an effort to ensure that interfacing  systems will operate  successfully
in the year 2000 the Corporation is conducting  integrated testing of individual
systems  already deemed to be Y2K compliant.  Although the formal testing period
is scheduled to be completed in September 1999, additional  verification testing
will continue through December 1999.

     For each of these  initiatives,  seven major categories of events have been
identified  for  contingency   plans.  These  categories  are  (1)  key  data  -
integrity/loss,    (2)   critical   software,   (3)   critical   hardware,   (4)
communications, (5) critical supplies and suppliers, (6) facilities, and (7) key
personnel.  The contingency plans also include a Y2K command center that will be
staffed 24 hours a day in the fourth quarter of 1999 and  continuing  into early
2000 for any problems that might occur due to Y2K. The staff will be composed of
technical experts to fix or advise what to fix if systems fail and knowledgeable
representatives  from each  business  unit.  Contingency  plans  continue  to be
developed and will be refined and adjusted throughout 1999.

     As of June 30, 1999, 100% of the Corporation's systems (excluding trucking)
have been  converted,  tested,  and deemed to be Y2K compliant.  Modification to
trucking systems comprises  approximately 10% of UPC's total Y2K workload and is
estimated to be 98% complete.  The remaining  modification to trucking's systems
is expected to be completed in the third quarter of 1999. Costs to convert UPC's
systems are  expensed as  incurred.  As of June 30,  1999,  more than 80% of the
costs of the Y2K project,  estimated to be $61 million  (pre-tax) in total, have
been  expensed.   Although  the   Corporation   believes  its  systems  will  be
successfully  modified,  failure  by it,  or by those  from  whom UPC  purchases
equipment,  or by other  entities  with whom UPC  exchanges  data, or on whom it
relies for data, to successfully  modify their systems,  could materially impact
operations and financial results in the year 2000.

Item 3.  Quantitative and Qualitative Disclosures about Market Risk

Disclosure concerning market  risk-sensitive  instruments is set forth in Note 5
to the Consolidated  Financial  Statements  included in Item 1 of Part I of this
Report and is incorporated herein by reference.

PART II.  OTHER INFORMATION

Item 1.  Legal Proceedings

The discussion of certain legal  proceedings  affecting the  Corporation  and/or
certain of its subsidiaries  set forth in Note 10 to the Consolidated  Financial
Statements included in Item 1 of Part I of this Report is incorporated herein by
reference.  In  addition  to  those  matters,  the  following  proceedings,   or
developments  in proceedings  presently  pending,  arose or occurred  during the
second quarter of 1999.

Bottleneck  Proceedings - As reported in the Corporation's Annual Report on Form
10-K for the year ended December 31, 1998 and Quarterly  Report on Form 10-Q for
the quarter  period  ended  March 31,  1999,  the U.S.  Court of Appeals for the
Eighth Circuit  entered an order on February 10, 1999 affirming a prior decision
by the  STB.  The  STB  decision  generally  reaffirmed  its  existing  position
regarding  the  obligation  of rail  carriers  to provide  rates for  bottleneck
segments  (lines of  railroad  that are  served by a single  railroad  between a
junction  and  an  exclusively-served   shipper  facility),  and  dismissed  two
complaint  proceedings  filed  by  shippers  challenging  a class  rate  for the
movement of coal to which UPRR and a predecessor were parties. On April 23, 1999
the Eighth Circuit denied a petition for rehearing  filed by two of the shippers
involved in the complaint proceeding.  On July 19, 1999 the Western Coal Traffic
League filed a petition for a writ of certiorari  in the United  States  Supreme
Court.

Labor  Matters - The UPC 1998 10-K  disclosed  that the  General  Counsel of the
National Labor Relations Board (NLRB) is seeking a bargaining order remedy in 12
cases involving Overnite  Transportation  Company (Overnite),  where a Teamsters
local union lost a representation  election, and that in four of the 12 cases an
administrative  law  judge  has  ruled  that  the  bargaining  order  remedy  is
warranted,  a ruling that  Overnite has appealed to the NLRB.  During the second
quarter,  an administrative law judge ruled in the remaining cases,  determining
that the  bargaining  order  remedy is  warranted  in seven of the eight  cases.
Overnite intends to appeal that ruling to the NLRB.

 27

Environmental Matters - As reported in the UPC 1998 10-K, the Railroad was named
as a  defendant  in a  criminal  misdemeanor  action  brought  by the  State  of
California,  and both the California  Department of Fish and Game and the United
States  Environmental  Protection Agency (USEPA) were seeking penalties,  as the
result of a diesel fuel spill at Norden,  California  in February  1997.  In the
second quarter,  the Railroad  settled the cases with the State of California by
payment of  $180,000.  The  Railroad  and the USEPA have reached an agreement in
principle  to settle that case for payment of  $125,000,  subject to the USEPA's
customary public comment procedures.
