               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 1998
     Annual  Report).  The results of  operations  for the three and nine months
     ended September 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 nine months
     ended September 30, 1999 and 1998, respectively:

         logistics  and  supply  chain  management  services,  which was sold in
         November 1998.
     [c] The  Corporation   does  not  have  significant   intercompany   sales
         activities. [d] "Other" includes the adjustment of a liability related
         to the discontinued operations of a former subsidiary (Note 4).
     [e] "Trucking"  includes goodwill  amortization of $5 million and $15
         million for the three months and nine months ended  September 30, 1998,
         respectively.
     [f] "Other"  includes  the  write-down  of the  investment  in  Overnite in
         connection with the attempted sale of Overnite (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 2,900  employees and relocated  4,500 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 $110 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 September
    30,  1999  and  1998   included  $13  million  and  $7  million   after-tax,
    respectively,  and for the nine months  ended  September  30, 1999 and 1998,
    included  $30  million  and  $36  million   after-tax,   respectively,   for
    acquisition-related costs for UPRR consolidation activities.

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


- -------------------------------------------------------------------------------
                                                   Original Cumulative  Current
        Millions of Dollars                         Reserve   Activity  Reserve
- -------------------------------------------------------------------------------
                                                                
    Contractual obligations.......................   $361       $361     $  -
    Severance costs...............................    343        264       79
    Contract cancellation fees and
      facility and line closure costs.............    145        126       19
    Relocation costs..............................    109         89       20
- -------------------------------------------------------------------------------
    Total.........................................   $958       $840     $118
- -------------------------------------------------------------------------------



    Merger  Liabilities - Merger liability  activity  reflects 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  two  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,  UPRR  purchased  an  additional  13%
    ownership interest for $87 million from one of its partners.  UPRR now holds
    a 26% ownership  share in the  consortium.  The  investment is accounted for
    under the equity method.

4.  Discontinued Operations

    Adjustment to 1994 Loss on Disposal of Discontinued  Operations - Net income
    for the  third  quarter  1999  included  a  one-time  after-tax  gain of $27
    million,  net of taxes of $16 million,  from the  adjustment  of a liability
    established  in  connection  with the  discontinued  operations  of a former
    subsidiary.

    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,  net of a  $198  million  tax  benefit,  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.

  9


    Credit  Risk - The  total  credit  risk  associated  with the  Corporation's
    counterparties  was $111  million at September  30,  1999.  UPC has received
    collateral  relating  to its hedging  activity  where the  concentration  of
    credit risk was substantial.

    Valuation - The fair market values of the Corporation's derivative financial
    instrument  positions  at  September  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
    September 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 September 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

 11

    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 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.
    Also,  during September 1999, the Corporation  issued $150 million of 7 3/8%
    notes with a maturity  date of  September  15, 2009.  The proceeds  from the
    issuance of these  debentures  and notes 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 $850 million
    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.

7.  Earnings Per Share - The following tables provide a  reconciliation  between
    basic and diluted  earnings  per share for the three  months and nine months
    ended September 30, 1999 and 1998:

9.  Ratio of Earnings to Fixed  Charges - The ratio of earnings to fixed charges
    has been computed on a consolidated basis.  Earnings represent income (loss)
    from  continuing  operations  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 nine months ended September 30,
    1998, fixed charges exceeded earnings by approximately $339 million.

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  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 or results
    of operations. 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.

 14


        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  Position (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.

Item 2. Management's Discussion and Analysis of Financial Condition
        and Results of Operations


               UNION PACIFIC CORPORATION AND SUBSIDIARY COMPANIES
                              RESULTS OF OPERATIONS

           Three and Nine Months Ended September 30, 1999 Compared to
              Three Months and Nine Months Ended September 30, 1998

Union Pacific  Corporation  (the  Corporation or 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.  All  earnings per share
information is stated on a diluted basis.

CONSOLIDATED

Net Income - Net income for the three months and nine months ended September 30,
1999 was $245  million  ($0.96 per share) and $568  million  ($2.27 per  share),
respectively,  compared  to $34  million  ($0.14  per  share) and a loss of $444
million ($1.80 per share) for the  comparable  periods in 1998. The increase was
driven  primarily by improved  operations  and service levels at UPC's Rail unit
which resulted in higher revenues and lower  expenses.  Net income for the third
quarter of 1999  included a one-time  after-tax  gain of $27 million  ($0.10 per
share) from the  adjustment of a liability  established  in connection  with the
discontinued  operations of a former subsidiary.  Net income for the nine months
ended  September  30, 1998 included a $262 million  after-tax  provision for the
expected loss from the proposed sale of Overnite. In the fourth quarter of 1998,
the Corporation  reclassified  Overnite's  results to continuing  operations and
reversed the loss from  discontinued  operations (see Note 4 to the Consolidated
Financial Statements).

Operating  Revenues - Operating  revenues  increased  $233 million (9%) and $537
million  (7%) for the three month and nine month  periods  ended  September  30,
1999,  respectively,  over the  comparable  periods in 1998.  The  increase  was
primarily due to higher 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 and $133 million in
revenue during the third quarter and first nine months of 1998, respectively.

Operating  Expenses - For the three and nine month periods  ended  September 30,
1999,  operating  expenses  decreased  $72 million (3%) and $677  million  (9%),
respectively,  over the comparable periods in 1998. Salaries, wages and employee
benefit  costs  increased in the third quarter of 1999 over the third quarter of
1998, due to one-time costs related to the Southern  Pacific merger  recorded in
the third quarter of 1999 (see Note 3 to the Consolidated Financial Statements),
higher rail volume and  inflation,  partially  offset by improved  productivity.
Fuel and  utilities  costs also  increased in the third quarter of 1999 over the
third quarter of 1998 due to increased volume,  partially offset by lower prices
(see  Note  5  to  the  Consolidated  Financial  Statements).  Depreciation  and
materials and supplies both increased slightly for both the three month and nine
month periods ended September 30, 1999 over the comparable  periods in 1998. The
increase in depreciation expense reflects increased capital spending,  while the


 16

increase in  materials  and supplies  reflects  higher rail  volumes.  All other
operating  expense  categories  decreased in the third  quarter of 1999 over the
comparable period in 1998. The factors primarily  responsible for such decreases
are substantially the same in the three and nine month periods and are discussed
below.

     For the nine month period, all operating expense categories  decreased over
the comparable 1998 period. Salaries, wages and employee benefit costs decreased
due to improved  productivity and lower corporate expenses,  partially offset by
higher rail volume and  inflation.  Equipment and other rents expense  decreased
primarily as a result of improved rail cycle times,  partially  offset by higher
rail  volumes.  Fuel and  utilities  costs were lower,  as lower fuel prices and
improved  fuel  efficiency  more than offset  volume  driven  increases  in fuel
consumption.  Casualty  costs  decreased due to lower than  expected  settlement
costs at the Rail unit. The decrease in other costs in 1999 reflected the impact
in 1998 of 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.

Operating  Income - Operating income increased $305 million and $1.2 billion for
the three and nine month periods ended  September 30, 1999,  over the comparable
periods in 1998, reflecting improved operations and service levels at UPC's Rail
unit,  which resulted in decreased  Rail  operating  expenses and increased Rail
revenues.

Non-Operating Items - Other income decreased $12 million in the third quarter of
1999 over the  comparable  period in 1998 due to the impact in the third quarter
of 1998 of a  telecommunications  contract  buyout  and the sale of a  corporate
aircraft. Other income decreased $40 million for the nine months ended September
30, 1999 over the comparable period in 1998, reflecting the additional impact of
the sale of the  Southern  Pacific  Rail  Corporation  (SP or Southern  Pacific)
headquarters  building and an insurance  recovery for 1997 flood damage recorded
in the second quarter of 1998.  Interest expense  decreased in the third quarter
of 1999 over the third  quarter of 1998,  due to lower average debt in the third
quarter of 1999,  but  increased  for the 1999 nine month  period as a result of
increased  average debt  levels.  Income taxes for both the three and nine month
periods  increased  over the  comparable  periods  in 1998 due to higher  income
before income taxes, partially offset by settlements related to prior tax years.

RAIL SEGMENT

Net  Income - Rail  operations  reported  net  income of $234  million  and $589
million  for the  three  months  and  nine  months  ended  September  30,  1999,
respectively,  compared to net income of $67  million  for the third  quarter of
1998 and a net loss of $87 million for the 1998 nine month period.  The increase
for both the three and nine  month  periods  resulted  primarily  from  improved
operations and service  levels,  increased  revenues in all commodity  lines and
lower operating costs.

Operating  Revenues - Rail  operating  revenues  increased $246 million (10%) to
$2,606  million and $615 million (9%) to $7,576 million for the quarter and nine
months ended September 30, 1999,  respectively,  over the comparable  periods in
1998.  Revenue carloads increased 9% and 7% for the three and nine month periods
ended  September 30, 1999,  respectively,  over the comparable  periods in 1998.
1999 commodity  revenues,  primarily  automotive and industrial,  were adversely
influenced due to the impact on rail traffic of the  implementation of the joint
acquisition of Conrail.

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


Agricultural - Agricultural  revenue increased for both the three and nine month
periods over the comparable  periods in 1998,  primarily due to stronger exports
and improved  service  levels,  which  resulted in increases in wheat,  corn and
beverages.

Automotive  -  Automotive  revenue  increased  for both the three and nine month
periods over the comparable periods in 1998, due to increased carloads caused by
strong domestic  production,  improvements in cycle times, price increases,  and
the negative impact in 1998 of a strike against a major auto manufacturer. These
gains  were  partially  offset by the  negative  impact on rail  traffic  of the
implementation of the joint acquisition of Conrail.

Chemical - Chemical revenue  increased for both the three and nine month periods
over the comparable periods in 1998, due to improved service levels and recovery
in demand for plastics, liquid and dry chemical and phosphorous, which increased
carloads.  These  gains  were  partially  offset by  declines  in soda ash and a
decline in demand for  fertilizers.  Average  revenue  per car  improved  due to
increased  longer-haul  plastics shipments and fewer shorter-haul  petroleum and
export sulfur moves.

 17


Energy - Energy revenue increased for both the three and nine month periods over
the  comparable  periods in 1998 due to  increases in the number of Powder River
Basin trains per day, tons per car and average train length.  Powder River Basin
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.
Average  revenue  per car  increased  resulting  from  changes in traffic mix as
longer-haul Powder River Basin traffic increased.

Industrial  Products - Industrial  Products revenue increased for both the three
and nine month  periods  over the  comparable  periods  in 1998 due to  stronger
demand and improved cycle times.  Carloads increased 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
lower-priced  foreign  steel and lost  volumes  from a major steel  producer who
filed for bankruptcy.  Average revenue per car increased due to a combination of
price increases and product mix changes.

Intermodal  -  Intermodal  revenue  increased  for both the three and nine month
periods  over the  comparable  periods in 1998 due to  increased  carloads,  and
increased  average revenue per car.  Carloads improved due to strong demand 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.  Average revenue per car increased due to positive
mix shifts and demand-driven price increases.

Operating  Expenses - Operating  expenses  decreased  $44 million  (2%) and $540
million  (8%)  for the  quarter  and  nine  months  ended  September  30,  1999,
respectively.

     Salaries, wages and employee benefit costs increased for the three and nine
month periods ended September 30, 1999 over the comparable  periods in 1998, due
to one-time costs related to the Southern  Pacific merger  recorded in the third
quarter of 1999 (see Note 3 to the Consolidated  Financial  Statements),  higher
rail volume and inflation, partially offset by improved productivity.

     Equipment  and other  rents  expenses  decreased  $9  million  (3%) and $94
million  (9%)  for the  quarter  and  nine  months  ended  September  30,  1999,
respectively,  due  primarily to  improvements  in cycle time and lower  prices,
partially offset by higher volume.

     Fuel and  utilities  expenses  were up $8 million (4%) and down $33 million
(6%) for the quarter and nine months ended September 30, 1999, respectively. The
quarterly increase was driven by higher volumes, while the year-to-date decrease
reflects lower fuel prices and improved  consumption rates,  partially offset by
higher volume.  The Railroad hedged 68% and 69% of its fuel  consumption for the
three and nine months  periods  ended  September 30, 1999,  respectively,  which
decreased fuel costs by $26 million and $7 million, respectively.  Expected fuel
consumption  for the remaining  three months of 1999 is 67% hedged at an average
of 41 cents per gallon  (excluding  taxes,  transportation  charges and regional
pricing spreads).

     Casualty  costs  declined $34 million  (33%) and $62 million  (20%) for the
quarter and nine months ended September 30, 1999, respectively, 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.

     Depreciation  and materials and supplies both  increased  slightly for both
the three and nine month  periods ended  September 30, 1999 over the  comparable
periods in 1998. The increase in depreciation expense reflects increased capital
spending,  while the increase in materials  and  supplies  reflects  higher rail
volumes.

 19


     Other costs  decreased  $39 million  (16%) and $407  million  (39%) for the
three and nine month periods ended September 30, 1999, respectively,  reflecting
the impact on 1998 results from 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 $290 million to $515 million and
$1.2 billion to $1.3 billion for the quarter and nine months ended September 30,
1999,  respectively.  Both 1999 and 1998  included the impact of one-time  costs
related to the Southern Pacific merger for severance, relocation and training of
employees.  The operating  ratio for the third  quarter of 1999 was 80.2%,  10.3
percentage  points better than 1998's 90.5% operating ratio. The operating ratio
for the first nine months of 1999 was 82.6%,  15.1 percentage points better than
1998's 97.7% operating ratio.

Non-Operating  Items - Other  income  decreased  $22 million  (49%) in the third
quarter  of 1999 over 1998 due to the  impact in the third  quarter of 1998 of a
telecommunications  contract buyout and the sale of a corporate aircraft.  Other
income  decreased $50 million (44%) for the nine months ended September 30, 1999
over the comparable period in 1998, reflecting the additional impact of the sale
of the SP headquarters  building and an insurance recovery for 1997 flood damage
recorded in the second quarter of 1998.  Interest  expense  decreased $4 million
(2%) in the third  quarter  of 1999 over the third  quarter of 1998 due to lower
average  debt in the third  quarter  of 1999.  Interest  expense  increased  $26
million (6%) for the nine months ended  September  30, 1999 over the  comparable
period in 1998 as a result of higher average debt levels year over year.  Income
taxes increased $105 million for the three month period and $403 million for the
nine month period, respectively, reflecting higher income before income taxes.

OTHER OPERATIONS

Trucking Product Line

Net Income - Trucking net income was $8 million and $28  million,  for the three
and nine month periods  ended  September  30, 1999,  respectively,  down from $9
million  (excluding  goodwill  amortization  of  $5  million)  and  $29  million
(excluding good will amortization of $15 million) for the comparable  periods in
1998. The decrease in net income for both periods was more than accounted for by
expenses related to Overnite's  contingency plans in response to activity by the
International  Brotherhood  of Teamsters  (Teamsters)  and a brief job action in
July.

Operating  Revenues - For the three and nine month periods  ended  September 30,
1999,  trucking  revenues  increased  $20 million  (8%) to $277  million and $27
million (3%) to $803 million, respectively, over the comparable periods in 1998.
The revenue  increase  resulted  from higher  volume,  reflecting  a new product
offering in the  northeast  United  States and Texas and from rate  improvements
resulting from increased average length of haul and yield improvement.

Operating  Expenses - For the three and nine month periods  ended  September 30,
1999,  operating  expenses  increased  $24 million (10%) to $269 million and $32
million (4%) to $770 million, respectively, over the comparable periods in 1998.
For the three and nine months  ended  September  30, 1999,  salaries,  wages and
employee  benefit  costs  increased  $14  million  (9%) to $169  million and $26
million  (6%)  to  $494  million,  respectively,  reflecting  wage  and  benefit
enhancements and expenses related to Overnite's contingency plans in response to
Teamster  activity.  Fuel and utilities  costs increased $2 million (18%) to $13
million  for the three month  period and $1 million  (3%) to $35 million for the
nine month period, due to higher volumes and increased fuel price per gallon (57


 20

cents in the third  quarter of 1999 compared to 48 cents in the third quarter of
1998), partially offset by favorable hedge activity.  Forty percent of estimated
remaining  1999 fuel  purchases  are hedged at an average of 45 cents per gallon
(excluding  taxes,   transportation   charges  and  regional  pricing  spreads).
Equipment and other rents  increased $4 million (20%) for the three month period
due to costs related to Teamster  activity and to the  alleviation of congestion
caused by closure of a regional competitor.

Operating Income - Trucking operations  generated operating income of $8 million
(excluding  goodwill  amortization  of $5 million) for the third quarter of 1999
and $33 million (excluding  goodwill  amortization of $15 million) for the first
nine months of 1999  compared to $12 million and $38 million for the  comparable
periods in 1998. The operating ratio for trucking operations (excluding goodwill
amortization  in 1998)  increased  to 97.1% in 1999  from  95.3% in 1998 for the
third  quarter  and  increased  to 95.9% in 1999 from 95.1% in 1998 for the nine
months ended September 30, 1998.

Recent Events - On October 24, 1999, the Teamsters began a job action at certain
Overnite facilities. As of November 9, 1999, approximately 30 Overnite terminals
had some  employees  who did not  cross  picket  lines,  and  approximately  870
employees,  6.7% of Overnite's  workforce,  did not report to work.  Overnite is
operating under its strike contingency plan, and has deployed  approximately 400
employee  volunteers to other Overnite locations and is using  approximately 200
temporary third-party  replacement workers. The Teamster activity is expected to
negatively  impact  Overnite's  results of operations  in the fourth  quarter of
1999.

     The Teamsters are the certified and  recognized  bargaining  agent at 22 of
Overnite's  locations employing  approximately 1,800 of Overnite's  workforce of
approximately  13,000.  Additionally,  proceedings  are pending in certain cases
where a Teamsters local union lost a representation  election. See Part II, Item
1, "Legal Proceedings - Labor Matters."

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).  For the three and nine
month periods ended September 30, 1999,  operating revenues declined $33 million
and  $105  million,  respectively,  over the  comparable  periods  in 1998,  due
primarily to the sale of Skyway in November  1998. For the three and nine months
ended  September  30, 1999,  operating  expenses  decreased $47 million and $154
million,  respectively,  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 for the three and nine month
periods ended  September 30, 1999 over the  comparable  periods in 1998 declined
$14 million and $49 million, respectively, and losses from continuing operations
declined  $13  million  and  $33  million,  respectively,  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 nine months of 1999,  cash  provided by
operations  was $1.5  billion,  compared to $209 million in 1998.  This increase
reflects  higher  earnings at the  Corporation's  Rail segment.  Working capital
improved  due to  continued  emphasis on  receivable  collection  efforts at the
Railroad and the timing of current liability payments.

 21


     Cash used in investing activities was $1.3 billion in the first nine months
of 1999,  compared to a use of $1.7  billion 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 used in equity and financing  activities was $138 million in the first
nine months of 1999,  compared to $2.0  billion  provided in 1998.  Cash used in
1999 principally reflects lower net borrowings ($600 million in 1999 compared to
$4.0 billion in 1998) offset by debt repaid  ($591  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 56.6% at September  30, 1999  compared to 58.0% at December 31,
1998 and 58.4% at September 30, 1998. Including the CPS as an equity instrument,
the ratio of debt to total  capital  employed  at  September  30, 1999 was 48.3%
compared to 49.4% at December 31, 1998 and 50.2% at September 30, 1998.

     At September 30, 1999 the  Corporation  had a $2.8 billion credit  facility
outstanding.  The  facility is  designated  for general  corporate  purposes and
expires in 2001.  During January 1999 the  Corporation  issued $600 million of 6
5/8% debentures with a maturity date of February 1, 2029.  During September 1999
the  Corporation  issued  $150  million of 7 3/8% notes with a maturity  date of
September 15, 2009. The proceeds from the issuance of these debentures and notes
were used for  repayment of debt and other  general  corporate  purposes.  Under
currently  effective shelf  registration  statements,  the Corporation may sell,
from time to time,  up to $850 million 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 to the  Consolidated
Financial  Statements).  In addition,  to the extent fuel hedges are ineffective


 22

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 the
remainder of 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.

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 is
complete, 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

 23


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 fourth  quarter of 1999.  Costs to convert
UPC's systems are expensed as incurred.  As of September 30, 1999, more than 88%
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.

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
third 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 Surface  Transportation  Board of the U.S.  Department of  Transportation
(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.  The Supreme Court
denied the petition on October 18, 1999.

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.  Overnite  appealed that ruling to the NLRB. On November 10, 1999 the
NLRB upheld the  decision of the  administrative  law judge in those four cases.
Overnite has appealed the NLRB's ruling. Additionally, during the second quarter
of 1999, an administrative  law judge ruled in the remaining cases,  determining
that the bargaining order remedy is warranted in seven of the eight cases.
Overnite has appealed that ruling to the NLRB.

Environmental  Matters - As reported in the UPC 1998 10-K, the District Attorney
for San Bernardino County,  California was investigating the Railroad's handling
of several hazardous material spills in Barstow and West Colton,  California. In
the third quarter of 1999,  the District  Attorney and the Railroad  agreed to a
settlement,  and on July 28, 1999 a stipulated judgement against the Railroad in
the amount of $350,000 was entered by the San  Bernardino  Superior  Court.  The
Railroad also agreed to pay certain costs of San  Bernardino  County  associated
with the incidents that were the subject of the  investigation.  These costs are
estimated at $20,000, but may ultimately be more or less than such amount.

Other Matters - On August 29, 1997,  an Amtrak train,  operating on UPRR tracks,
struck  a car at a  crossbuck-protected  crossing  near  Warrensburg,  Missouri,
injuring  Kimberley R. Alcorn,  a passenger in the car. Ms. Alcorn  brought suit
against  UPRR and  Amtrak  in the  Circuit  Court of  Jackson  County,  Missouri
Division No. 10. On  September  24, 1999, a jury found that Amtrak and UPRR were
negligent in causing the  accident.  The jury awarded Ms.  Alcorn  approximately
$40.3 million in  compensatory  damages,  and, on September 29, 1999,  found the
Railroad and Amtrak liable for an additional  $120 million in punitive  damages.
The defendants are pursuing multiple avenues of relief from the jury awards. The
Railroad  believes  that the damage awards are not supported by the facts or the
law,  and that the trial court and/or the  appellate  courts will either grant a
new trial or will substantially reduce the amount of damages. Under the terms of
an existing  agreement,  Amtrak will continue to defend UPRR's interests in this

 25


litigation  and UPRR believes  that Amtrak and its insurers,  under the terms of
the agreement, will hold UPRR harmless from any final judgment.
