      NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                          (Unaudited)
                                
1. Responsibilities for Financial Statements - The condensed 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.  The Condensed Statement of
   Consolidated Financial Position at December 31, 1997 is derived from audited
   financial statements.  The condensed 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,
   1997.  The results of operations for the three months ended March 31, 1998
   are not necessarily indicative of the results for the entire year ending
   December 31, 1998.  Certain 1997 amounts have been reclassified to conform
   to the 1998 financial statement presentation.

2. Acquisition of Southern Pacific Rail Corporation (Southern Pacific or SP) -
   UPC consummated the acquisition of Southern Pacific in September 1996.  The
   acquisition of Southern Pacific was accounted for using the purchase method. 
   SP's results were fully consolidated with the Corporation effective October
   1, 1996.  On February 1, 1998, Union Pacific Railroad Company (UPRR) was
   merged with and into Southern Pacific Transportation Company (SPT), the
   principal SP rail affiliate (the SPT    Merger), with SPT continuing as the
   surviving corporation and changing its  name to "Union Pacific Railroad
   Company" immediately following the SPT Merger.  Immediately prior to the SPT
   Merger, SPT was a wholly-owned, indirect subsidiary of UPC, and UPRR was a
   subsidiary of UPC, with all of the issued and outstanding shares of voting
   stock of UPRR being owned, directly or indirectly, by UPC. UPRR and SPT
   operated as a unified system before and after the SPT Merger.

   In connection with the continuing integration of UPRR and Southern Pacific's
   rail operations (collectively, the Railroad), UPC is continuing to eliminate
   duplicate positions (primarily positions other than train crews), relocate
   positions, merge or dispose of redundant facilities, dispose of certain rail
   lines and cancel uneconomical and duplicative SP contracts.  The Corporation
   has also repaid certain of Southern Pacific's debt obligations. UPC
   recognized a $958 million liability in the Southern Pacific purchase price
   allocation for costs associated with SP's portion of these activities. 

   Through March 31, 1998, a total of $323 million in merger-related costs were
   paid by the Corporation and charged against these reserves, composed of
   approximately $160 million and $70 million, respectively, for severance and
   relocation payments made to approximately 3,700 Southern Pacific employees,
   and approximately $63 million for labor protection payments. The Corporation
   expects that the remaining merger payments will be made over the course of
   the next five years as the rail operations of UPRR and SP are integrated and
   labor negotiations are completed and implemented.

   In addition, the Railroad expects to incur approximately $206 million in
   acquisition-related costs through 1999 for severing or relocating UPRR
   employees, disposing of certain UPRR facilities, training and equipment
   upgrading.  These costs will be charged to expense as incurred over the next
   two years.  Net income for the three months ended March 31, 1998 includes 
   $18 million in acquisition-related operating costs.

   3.  Financial Instruments - The Corporation uses derivative financial
   instruments in limited instances 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. 

   The Corporation addresses market risk related to these instruments by
   selecting instruments whose value fluctuations correlate highly with the
   underlying item being hedged.  Credit risk related to derivative financial
   instruments, which is minimal, is managed by requiring minimum credit
   standards for counterparties and periodic settlements.  The total credit 
   risk associated with the Corporation's counterparties was $73 million at 
   March 31, 1998.  The Corporation has not been required to provide, nor 
   has it received, any collateral relating to its hedging activity.  

   The fair market value of the Corporation's derivative financial instrument
   positions at March 31, 1998 was 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 zero coupon U.S.
   treasury rate and swap spread.

   Interest Rates - The Corporation controls its overall risk relating to
   fluctuations in interest rates by managing the proportion of fixed and
   floating rate debt instruments within its debt portfolio over a given 
   period.  Derivatives are used in limited circumstances as one of the tools 
   to obtain the targeted mix.  The mix of fixed and floating rate debt is 
   largely managed through the issuance of targeted amounts of such debt 
   as debt maturities occur or as incremental borrowings are required.  The
   Corporation also obtains additional flexibility in managing interest cost
   and the interest rate mix within its debt portfolio by issuing callable fixed
   rate debt securities. 

   At March 31, 1998, the Corporation had outstanding interest rate swaps on
   $260 million of notional principal amount of debt (3% of the total debt
   portfolio) with a gross fair market value asset position of $73 million and
   a gross fair market value liability position of $25 million.  These contracts
   mature over the next one to seven years. Interest rate hedging activity
   increased interest expense by $1 million in the first quarter of 1998 and by
   $2 million in the first quarter of 1997.

   Fuel - Over the past three years, fuel costs approximated 10% of the
   Corporation's total operating expenses.  As a result of the significance of
   the fuel costs and the historical volatility of fuel prices, the
   Corporation's transportation subsidiaries periodically use swaps, futures and
   forward contracts to mitigate the impact of fuel price volatility. The intent
   of this program is to protect the Corporation's operating margins and overall

6

   profitability from adverse fuel price changes.  

   At March 31, 1998, the Railroad and Overnite Transportation Company
   (Overnite), the Corporation's trucking subsidiary, had hedged 49% and 38%,
   respectively, of their estimated remaining 1998 diesel fuel consumption at
   $0.51 and $0.52 per gallon, respectively, on a Gulf Coast basis.  At March
   31, 1998, the Railroad had outstanding swap agreements covering its fuel
   purchases of $267 million, with gross and net liability positions of $28
   million.  Overnite had outstanding swap agreements of $8 million, with gross
   and net liability positions of $1 million.  Fuel hedging increased first
   quarter 1998 fuel expense by approximately $15 million and had no impact on
   first quarter 1997 fuel expense.

4. Ratio of Earnings to Fixed Charges - The ratio of earnings to fixed charges
   has been computed on a total enterprise basis.  Earnings represent income
   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 expense, and
   the estimated interest portion of rental charges.  For the three months ended
   March 31, 1998, fixed charges exceeded earnings by approximately $116
   million.

5. Commitments and Contingencies - There are various claims and lawsuits pending
   against the Corporation and certain of its subsidiaries.  Certain customers
   have submitted claims or stated their intention to submit claims to the
   Railroad for damages related to the delay of shipments as a result of
   congestion problems, 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 expects
   additional claims by shippers. UPC will continue to evaluate the adequacy of
   its reserves for claims and expects to add to such reserves as appropriate.

   The Railroad is also party to certain regulatory proceedings before the
   Surface Transportation Board of the U.S. Department of Transportation (STB). 
   One proceeding pertains to rail service problems in the western United
   States. As an outgrowth of this proceeding, the STB has issued an emergency
   service order imposing certain temporary measures on the Railroad designed,
   among other things, to reduce congestion on the Railroad's lines in the
   Houston, Texas area.  A second proceeding, initiated under the STB's
   continuing oversight jurisdiction with respect to the Corporation's
   acquisition of Southern Pacific and consolidation of Southern Pacific with
   UPRR (and separate from the STB's regularly scheduled annual proceeding to
   review the implementation of the merger and the effectiveness of the
   conditions that the STB imposed on it), is for the purpose of considering the
   justification for and advisability of any proposals for new remedial
   conditions to the merger as they pertain to service in the Houston,
   Texas/Gulf Coast area, including proposals by Kansas City Southern Railway
   Company (KCS), Texas Mexican Railway Company (Tex Mex) and the Greater
   Houston Partnership (GHP) for the forced transfer by the Railroad to Tex Mex
   of certain lines and facilities in and around Houston, the establishment of
   a "neutral" switching operation in the greater Houston area, and the

7

   permanent adoption of provisions in the STB's emergency service order that
   expanded Tex Mex's right to handle traffic to and from Houston.  In addition,
   the STB has initiated various inquiries and formal rulemaking proceedings
   regarding certain elements of rail regulation following two days of hearings
   by the STB at the request of two members of Congress and in response to
   shippers' expressions of concern regarding railroad service quality, railroad
   rates and allegedly inadequate regulatory remedies.  If the Railroad is
   unsuccessful in eliminating the remaining congestion and service problems
   affecting its system, the STB could issue a new emergency service order upon
   the expiration of the current one and order the Railroad to take additional
   actions including, among other things, further diversions of traffic or the
   transfer of certain rail lines or other facilities to other railroads.  In
   addition, there can be no assurance that the proposals advanced by parties
   in the remedial conditions proceeding or the proceedings initiated in
   response to the rail regulation hearings will not be approved in some form. 
   Should the STB or Congress take aggressive action in the rail regulation
   proceedings (e.g., by making purportedly competition-enhancing changes in
   rate and route regulation and "access" provisions), the adverse effect on the
   Railroad and other rail carriers could be material.

   The Corporation is also subject to Federal, state and local environmental
   laws and regulations, and is currently participating in the investigation and
   remediation of numerous sites.  Where the remediation costs can be reasonably
   determined, and where such remediation is probable, the Corporation has
   recorded a liability.  In addition, the Corporation and its subsidiaries
   periodically enter into financial and other commitments and have retained
   certain contingent liabilities upon the disposition of formerly-owned
   operations.
 
   In addition, UPC and certain of its officers and directors are currently
   defendants in two purported class action securities lawsuits, and certain
   current and former directors of the Corporation are currently defendants in
   a purported derivative action filed on behalf of the Corporation.  The class
   action suits allege, among other things, that management failed to disclose
   properly the Railroad's service and safety problems and thereby issued
   materially false and misleading statements concerning the merger with SP and
   the safe, efficient operation of its rail network.  The derivative action
   alleges, among other things, that the named current and former directors
   breached their fiduciary duties to the Corporation by approving the mergers
   of SP and Chicago and North Western Transportation Company into the
   Corporation without ensuring that the Corporation or the Railroad had
   adequate systems in place to effectively integrate those companies into the
   operations of the Corporation and the Railroad.  Because both the size of the
   class and the damages are uncertain, UPC and the Railroad are unable at this
   time to determine the potential liability, if any, which might arise from
   these lawsuits.  Management believes that these claims are without merit and
   intends to defend them vigorously.

   It is not possible at this time for the Corporation to fully determine the
   effect of all unasserted claims on its consolidated financial condition,
   results of operations or liquidity; 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

8

   condition.

6. Accounting Pronouncements - In June 1997, the Financial Accounting Standards
   Board (FASB) issued Statement No. 130, "Reporting Comprehensive Income" 
   (FAS 130)that is effective for all periods in 1998, including interim 
   periods.  UPC has adopted the provisions of FAS 130 effective January 1, 
   1998.  The components of comprehensive income include, among other things, 
   changes in the market value of futures contracts which qualify for hedge 
   accounting and a net loss recognized as an additional pension liability but 
   not yet recognized as net periodic pension cost. The impact of adopting 
   FAS 130 for the three months ended March 31, 1998 was approximately 
   $2 million. 
   
   Also in June 1997, the FASB issued Statement No. 131, "Disclosures about 
   Segments of an Enterprise and Related Information," effective December 31, 
   1998. The Corporation currently complies with most provisions of this 
   Statement, and any incremental disclosure required by that Statement is 
   expected to be minimal. 

   In February 1998, the FASB issued Statement No. 132, "Employers' Disclosures
   about Pensions and Other Postretirement Benefits" effective in 1998 
   (FAS 132).  FAS 132 revises and standardizes disclosures required by 
   FAS 87, 88, and 106.  Restatement of the retirement plan footnote will be 
   required for all earlier periods presented in comparative financial  
   statements at December 31, 1998.


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

              UNION PACIFIC CORPORATION AND SUBSIDIARY COMPANIES
                            RESULTS OF OPERATIONS
           Quarter Ended March 31, 1998 Compared to March 31, 1997 

Southern Pacific Rail Corporation (Southern Pacific or SP) Acquisition - UPC
consummated the acquisition of Southern Pacific in September 1996.  The 
aggregate Southern Pacific purchase price was $4.1 billion ($2.5 billion in 
UPC common stock and $1.6 billion in cash). The acquisition of Southern Pacific 
was accounted for as a purchase. Southern Pacific's results have been fully
consolidated with the Corporation since October 1, 1996. (See Note 2 to the
Condensed Consolidated Financial Statements). Throughout 1997 and continuing in
the first quarter of 1998, Union Pacific Corporation (UPC or the Corporation)
continued the process of implementing the acquisition of Southern Pacific. 

On February 1, 1998, Union Pacific Railroad Company (UPRR) was merged with and
into Southern Pacific Transportation Company (SPT), the principal SP rail
affiliate (the SPT Merger), with SPT continuing as the surviving corporation 
and changing its name to "Union Pacific Railroad Company" immediately 
following the SPT Merger. Immediately prior to the SPT Merger, SPT was a 
wholly-owned, indirect subsidiary of UPC, and UPRR was a subsidiary of UPC, 
with all of the issued and outstanding shares of voting stock of UPRR being 
owned, directly or indirectly, by UPC. UPRR and SPT operated as a unified 
system before and after the SPT Merger.

The Corporation expects to complete the full integration of the railroad
operations of UPRR and the Southern Pacific rail subsidiaries (collectively, the
Railroad) during 1999.  The Corporation believes that the full implementation of
the merger will result in shorter routes, faster transit times, better on-time
performance, expanded single-line service and more efficient traffic flow.

9

As a result of the SP acquisition, UPC now operates the largest rail system in
the United States, with nearly 35,000 route miles linking Pacific Coast and Gulf
Coast ports to the Midwest and eastern U.S. gateways.  The Corporation also owns
Overnite Transportation Company (Overnite), a major interstate trucking company
specializing in less-than-truckload (LTL) shipments.

CONGESTION AND SERVICE ISSUES
As previously reported in the Corporation's 1997 Annual Report on Form 10-K,
congestion in and around Houston and the coastal areas of Texas and Louisiana
(the Gulf Coast region) began to have a material adverse effect on the
Corporation's operations and earnings in the third quarter of 1997.  System
congestion started in the Gulf Coast region and spread throughout the system as
the Railroad shifted resources to help mitigate the problem in the Gulf Coast
region.  The congestion was brought on by, among other things, crew shortages 
and restricted track access caused by necessary track maintenance on former 
Southern Pacific lines, increased demand, washouts due to severe weather, 
derailments and congestion at Texas/Mexico gateways.  Traffic slowed further 
as rail yards in the Gulf Coast region filled, slowing access into and out of 
the yards and forcing trains to be held on sidings.  Slower average train 
velocity led to a greater need for locomotives in the region.  As traffic in 
the region backed up and the Railroad redeployed locomotives to the Gulf Coast 
region to help alleviate local congestion, congestion problems spread to 
other parts of the Railroad's system during the third and fourth quarters of 
1997.

To restore service to acceptable levels, the Railroad implemented a Service
Recovery Plan (the Plan) in October, 1997.  The Plan focuses on reducing the
number of cars on the system and restoring system velocity, which, in turn,
results in more reliable service to customers.  Implementation of the Plan has
resulted in improvement in the overall operation of the Railroad and is
addressing congestion problems in the Gulf Coast region and the surrounding
southeast portion of the Railroad's system (although intermittent periods of
congestion continue to arise in other regions, primarily in the Midwest). In 
late March and early April 1998, congestion in the Gulf Coast region was 
aggravated by several severe storms and congestion caused by operational 
problems on Mexican railroad lines south of Laredo, Texas.  However, 
operational initiatives subsequently implemented by the Railroad, including 
the Railroad's embargo of most southbound traffic destined for the Laredo 
gateway described below, have substantially reduced congestion on the 
Railroad's lines in the Gulf Coast region.

In connection with its integration with Southern Pacific, the Company has
implemented (i) TCS in the southeast portion of UPRR's system, which includes 
the Gulf Coast region, where the cutover to TCS occurred on December 1, 1997, 
(ii) directional running from Dexter Junction, Missouri, on the north, 
across Arkansas, western Louisiana and eastern Texas to the Houston and 
San Antonio areas on the south, beginning on February 1, 1998 and 
(iii) the hub-and-spoke labor agreements in Texas and Arkansas.  Although 
the Company believes that the full implementation of these changes is 
essential to achieving significant long-term benefits, their implementations 
also contributed to the persistence of congestion in the effected Gulf Coast 
region during late 1997 and early 1998.  
 
On March 28, 1998, the Railroad embargoed most southbound traffic destined for
the Laredo, Texas gateway to address worsening congestion at that gateway and
clear the backlog of cars waiting to cross into Mexico.  The embargo applied to
grain, chemicals, industrial products and coal, but not finished automobiles,
auto parts or intermodal traffic or any northbound traffic through Laredo.  The
Railroad rerouted some of the embargoed traffic through other Railroad gateways
to Mexico, none of which were subject to the embargo.  The Railroad believed 
that this embargo was necessary because congestion problems principally 
within Mexico and agricultural inspection delays at the border that affected 
the Laredo gateway had worsened during the weeks preceding the imposition of 
the embargo and were affecting other areas within the southeast region of its 
system, resulting in a substantial backlog of cars waiting to move south to 
Laredo. Imposition of the embargo quickly resulted in a significant reduction 
in the backlog of cars. 

10

Accordingly, on April 14, 1998, the Railroad amended the embargo to introduce
permitting to control traffic volumes.  The permitting system allowed customers
to move traffic that had been embargoed while allowing the Railroad to meter
southbound traffic to prevent any surge of business that could again block the
Laredo crossing. On April 16, 1998, the Railroad further amended the embargo to
eliminate permit requirements for domestic shipments terminating at Laredo, and
on April 22, 1998, the Railroad canceled the embargo.

Financial Impact of Congestion - The Corporation has estimated that the cost of
the congestion-related problems for the three months ended March 31, 1998 was
approximately $260 million, after tax, which reflected the combined effects of
lost business, higher costs associated with system congestion, costs
associated with implementation of the Plan, alternate transportation and 
customer claims.  Although progress has been made in improving service, the 
Railroad expects these problems to continue to have an adverse impact on 1998 
results. In addition, as a result of recent operating losses incurred by the 
Railroad and in order to fund its capital programs, the Corporation has 
incurred substantial incremental debt since December 31, 1997 and obtained 
additional financing from a private placement of preferred securities.  (See
Changes in Financial Condition and Other Developments)  The timing 
of the Corporation's return to profitability will be determined by how rapidly 
it is able to eliminate congestion and return to normal operations throughout 
its system.

FINANCIAL RESULTS
CONSOLIDATED - The Corporation reported a net loss of $62 million or $0.25 per
diluted share for the first quarter of 1998, compared to 1997 net income of $128
million or $0.52 per diluted share.  This earnings decrease resulted primarily
from continued congestion and service issues at the Railroad, which were 
slightly offset by improved operating results at Overnite.  

Operating revenues decreased $224 million (8%) to $2,586 million in 1998,
reflecting an 11% decrease in volumes at the Railroad, which were somewhat 
offset by a 20% increase in revenues at Overnite.

Operating expenses increased $62 million (3%) to $2,527 million in 1998.
Congestion-related costs and wage inflation, partially offset by net merger
benefits and volume-related cost savings, caused salaries, wages and employee
benefits to increase $52 million.  Congestion was also a contributing factor,
along with unfavorable rates, to an increase in equipment and other rents by $41
million.  Lower volumes and the absence of 1997 maintenance projects at the
Railroad were the primary factors causing a decrease in materials and supplies
($13 million).  Fuel and utility costs fell $75 million (25%), principally the
result of decreased volumes at the Railroad and a 15% decrease in fuel prices at
both the Railroad and Overnite.  Depreciation charges rose $5 million, primarily
due to the UPC's extensive capital spending on its equipment and rail
infrastructure.  Other costs increased $52 million, primarily resulting from
miscellaneous costs associated with the congestion and service recovery. 
Personal injury costs and casualty accruals fell $6 million and $3 million,
respectively, while professional fees and other taxes rose $7 million and $4
million, respectively.

Consolidated operating income fell $286 million (83%) to $59 million in 1998,
principally because of declining results at the Railroad, slightly offset by
improved results at Overnite. Other income fell $15 million, primarily 
reflecting fewer real estate sales and lower rental income resulting from the 
sale of the sign board business in 1997.  Interest expense increased 
$11 million, the result of higher debt levels, offset by favorable interest 

11

rates.  Income taxes decreased $120 million to a $43 million benefit, 
primarily reflecting lower income before income taxes.

Railroad - The Railroad lost $32 million in the first quarter of 1998, compared
to net income of $170 million a year ago.  This decline in earnings is the 
result of the continuing effect of congestion on the Railroad's operations. 
Both periods included the impact of one-time SP merger-related costs for 
severance, relocation, and training of employees ($18 million reduction in 
net income in 1998 and $9 million reduction in net income in 1997).  
The operating ratio for the first quarter of 1998 was 97.7, which includes 
approximately 15 points estimated to be attributable to congestion costs 
(both lost business and incremental operating costs).  This compares to 86.2 
for the same period in 1997.  Operating revenues fell $279 million (11%) 
to $2.28 billion in 1998.  This decrease reflects continuing congestion, the 
impact of the Asian crisis on export grain and intermodal markets and weak 
grain demand as farmers delay shipments due to the current grain price 
environment. Average commodity revenue per car (ARC) fell 1% to $1,149 per car, 
while total carloadings fell 9% (approximately 189,000 cars).  Commodity 
revenue in 1998 fell 10% over the same period in 1997 as shown in the table 
below.

                        =========    ======  ==========     ==========   ====

Agricultural Products: Commodity revenue fell 22% to $316 million.  Carloadings
declined 18% to 203,000 cars, primarily the result of a 25% decrease in corn
volumes due to soft export demand (strong foreign production and the effect on
exchange rates due to the Asian crisis), as well as continued congestion. Most
agricultural products suffered from congestion problems and related equipment
shortages; meals and oils were the only bright spot, as U.S. producers 
benefitted from strong export markets, primarily to Mexico.  Average 
commodity revenue per car declined 5%, primarily the result of weak exports, 
which significantly reduced the average length of haul.

Automotive: Commodity revenue fell 3% to $230 million, in spite of a 1% increase
in carloadings reflecting new business opportunities and steady economic
conditions in the industry. Strong demand and the new Ford business led the 3%
increase in finished autos carloadings while parts volumes fell 2% resulting 
from congestion-related diversions of traffic and inventory control by major
manufacturers. Average commodity revenue per car declined 4%, resulting from
generally shorter haul Ford business and less long-haul Mexico business.

Chemicals: Carloadings declined 6% to 223,000 cars and commodity revenue
decreased $44 million (10%) to $390 million.  The decline in volume resulted

12

principally from system congestion (partially the result of congestion of 
traffic crossing at the Mexican border), which more than offset strong market 
demand.  Average commodity revenue per car declined 4% due to generally 
shorter hauls (storage-in-transit moves for plastic and growth in short-haul 
potash moves) and unfavorable product mix.

Energy (Primarily Coal): Commodity revenue fell 3% to $497 million in 1998,
driven by a 3% decrease in carloadings. Continued congestion problems, 
diversions of business to competing roads and a late February blizzard led 
the decline, despite strong demand.  Average commodity revenue was flat, 
quarter over quarter.  Powder River Basin (PRB) train cycles fell slightly 
quarter-over-quarter, 24.8 in 1998 vs. 25.1 in 1997, however longer trains 
(117.6 cars/train in 1998 vs. 114.1 in 1997) boosted loads by approximately 
3,200 units helping to improve PRB business versus 1997.  All other mine 
locations posted declines, largely due to congestion and related train cycle 
issues.

Industrial Products: Carloadings decreased 10% while commodity revenue declined
9% to $436 million.  Volume declines resulted primarily from continued 
congestion (in the Southern tier and the Pacific Northwest) as well as the 
Railroad's sale of its Duck Creek North line in 1997. Average commodity 
revenue per car improved 1%, the result of the absence of shorter-haul Duck 
Creek business and favorable mix changes. 

Intermodal: Commodity revenue declined 14% to $358 million while carloadings 
fell 12% to 590,000 loads-the result of continued congestion and related 
diversions of traffic, as well as equipment imbalances caused by strong 
imports and weak exports.  Average commodity revenue per car fell 1%, as 
unfavorable mix was largely offset by new longer haul business.
  
Operating expenses were $2,231 million, $21 million (1%) higher than the first
quarter 1997 operating costs of $2,210 million.  Higher operating costs reflect
an estimated $77 million of congestion-related costs ($148 million of 
congestion-related costs offset by $71 million of volume savings from lower 
business levels).  The impact of congestion was partially offset by lower fuel 
costs, merger benefits and volume-related cost savings, as carloads were 
off 9% and gross-ton miles were down 10%.
    
Labor expense was $29 million (3%) higher than 1997, as net congestion-related
costs and wage inflation were partially offset by merger consolidation benefits
and volume-related cost savings.  Quarter-over-quarter, the work force levels
were virtually flat, as merger-related reductions and attrition were offset by
new hiring for train and engine crews.

Depreciation expense grew $6 million or 2% to $246 million due to the Railroad's
extensive capital program in 1997 and 1998.  The Railroad spent over $2 billion
on capital projects in 1997 and anticipates spending $2.2 billion in 1998 of
which $400 million will be merger-related. 

Materials and Supplies costs for the quarter were down $16 million (11%) from
first quarter 1997.  More rebuild projects (which are capitalized) and less 
maintenance projects in 1998 plus the absence of large program maintenance
projects on freight cars in 199 accounted for the quarter-over-quarter decline.

Fuel and Utilities expenses were down $73 million or 26% from 1997, reflecting
lower fuel prices and congestion-related volume declines. A reduction in 
gross-ton 

13

miles quarter-over-quarter (down 10%) generated volume-related fuel savings
of $24 million versus 1997.  Prices were down 11.7 cents per gallon to 63.6
cents, saving $33 million.  The fuel consumption rate of 1.416 gallons per
thousand gross-ton miles improved 3% from last year's 1.457 (largely slower
locomotive speeds), lowering UP's fuel costs by another $7 million.
  
Rent Expense was up 13% ($42 million) versus 1997, as system congestion (which
hindered car cycle times) combined with unfavorable rates (strong market demand
for equipment) to drive up equipment rent costs.

Other Costs increased $33 million (9%) from 1997, reflecting costs for customer
claims and service recovery caused by the system congestion offset by merger
consolidation benefits (trackage rights reimbursements and contract pricing
savings) and cost savings from administrative cost control efforts.

Operating income declined $300 million (85%) to $53 million in 1998, reflecting
the effect of continued congestion and service issues.  Interest expense
increased $12 million to $134 million, principally resulting from higher debt
levels.  Other income, net, declined $18 million due to the absence of the Duck
Creek North branch line sale in 1997.  Income taxes decreased $128 million to a
benefit of $31 million, primarily reflecting lower income before income taxes.

Trucking - During 1997, Overnite continued to benefit from several strategic
initiatives, implemented in 1996, aimed at better matching its operations to the
current trucking industry business environment. Actions taken included workforce
reductions, service center consolidations, centralization of the linehaul
management process and pricing initiatives targeting Overnite's lowest margin
customers.  Primarily as a result of these initiatives, Overnite increased its
net income from $1 million in the first quarter of 1997 to $10 million net 
income in the first quarter of 1998 (excluding goodwill amortization of 
$5 million in each period).

Overnite's operating revenues increased  $43 million (20%) to $257 million, as
a 13% increase in volumes combined with a 7% increase in average 
prices--resulting from Overnite's pricing initiatives.  Higher volumes 
reflected a 15% increase in LTL tonnage, somewhat offset by a 14% decrease 
in truckload volumes. 

Operating expenses increased $30 million (14%) to $244 million. Salaries, wages
and employee benefit costs increased $19 million (14%) to $154 million,
reflecting workforce increases, higher volumes, and wage and benefit inflation. 
An increased use of intermodal rail service and contract linehaul carriers 
caused an $8 million increase in purchased services.  Fuel costs declined 
$.5 million, as a 15% decrease in fuel prices was offset by a 10% 
volume-related increase in fuel consumption. Higher volumes caused increases 
in materials and supplies ($2 million). Overnite generated operating income 
of $13 million for the first quarter of 1998, compared to breaking even for 
the comparable period a year ago (excluding goodwill amortization of $5 
million in each period). Overnite's operating ratio (including goodwill 
amortization) improved to 96.8 in 1998 from 102.2 in 1997.

Corporate Services and Other Operations - Expenses related to Corporate Services
and Other Operations (consisting of corporate expenses, third-party interest
charges, intercompany interest allocations, other income and income taxes 
related to the Corporation's holding company operations, and the results of 
other operating units) decreased $3 million to $35 million in 1998.  This 
decrease

14

         
largely reflects lower Corporate interest and insurance costs.  Other operating
units generated an operating loss of $3 million in the first quarter of 1998,
compared to the same results during the comparable period in 1997. 

      CHANGES IN FINANCIAL CONDITION AND OTHER DEVELOPMENTS

FINANCIAL CONDITION - During the first three months of 1998, cash from 
operations was a negative $117 million, compared to $251 million in 1997.  
This $368 million decrease primarily reflects lower earnings and timing of 
working capital requirements due to the continuing congestion as well as 
merger consolidation spending.

Cash used in investing activities was $553 million in the first quarter of 1998
compared to $434 million in 1997. This increase primarily reflects higher 
capital spending by the railroad, incuding merger related spending.

Cash provided by equity and financing activities was $771 million in the first
quarter of 1998 compared to $86 million in 1997.  Cash provided in 1998
principally reflects higher net borrowings ($1.76 billion), offset by debt 
repaid of $888 million. The ratio of debt to total capital employed increased 
to 53.6% at March 31, 1998, compared to 50.9% at December 31, 1997 and 50.7% 
at March 31, 1997.  This change resulted from the increase in debt levels 
from year-end 1996.  

In February 1998, the Corporation announced that its Board of Directors had 
taken certain steps, including authorizing the issuance of equity-related 
securities and the reduction of the first quarter 1998 common stock dividend 
to 20 cents per share from 43 cents per share in the previous quarter, to 
ensure that the Railroad maintains the financial flexibility critical to 
funding its 1998 capital program.  On April 1, 1998, the Corporation 
completed a private placement of $1.5 billion of 6-1/4% preferred securities 
of Union Pacific Capital Trust, a statutory business trust sponsored by the 
Corporation, which securities are convertible into common stock of the 
Corporation at an initial conversion price of $68.90 (the Convertible 
Preferred Securities). Proceeds from the sale of the Convertible  Preferred 
Securities were used for repayment of borrowings.  (See "Part II.  OTHER 
INFORMATION; Item 2. Changes in Securities and Use of Proceeds.")

The Convertible Preferred Securities will be presented as a separate line item
in the consolidated balance sheet for the second quarter of 1998 between
liabilities and equity and appropriate disclosures will be included in the 
notes to the financial statements.  For financial reporting purposes, the 
Corporation will record distributions payable on the Convertible Preferred 
Securities as a financing charge to earnings in the statement of consolidated 
income.  

                             OTHER MATTERS

Accounting Pronouncements - In June 1997, the Financial Accounting Standards
Board (FASB) issued Statement No. 130, "Reporting Comprehensive Income" 
(FAS 130) that is effective for all periods in 1998.  UPC has adopted the 
provisions of FAS 130 effective January 1, 1998.  The components of 
comprehensive income include, among other things, changes in the market value 
of futures contracts which qualify for hedge accounting and a net loss 
recognized as an additional pension liability but not yet recognized as net 
periodic pension cost. The impact of adopting FAS 130 for the three months 
ended March 31, 1998 was approximately $2 million. 
             
15

Also in June 1997, the FASB issued Statement No. 131, "Disclosures about 
Segments of an Enterprise and Related Information," effective December 31, 
1998. The Corporation currently complies with most provisions of this 
Statement, and any incremental disclosure required by that Statement is 
expected to be minimal. 

In February 1998, the FASB issued Statement No. 132, "Employers' Disclosures
about Pensions and Other Postretirement Benefits" (FAS 132) effective in 1998. 
FAS 132 revises and standardizes disclosures required by FAS 87, 88, and 106.
Restatement of the retirement plan footnote will be required for all earlier
periods presented in comparative financial statements at December 31, 1998.

Commitments and Contingencies -There are various claims and lawsuits pending
against the Corporation and certain of its subsidiaries.  Certain customers 
have submitted claims or stated their intention to submit claims to the 
Railroad for damages related to the delay of shipments as a result of 
congestion problems, 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 expects additional 
claims by shippers. UPC will continue to evaluate the adequacy of its 
reserves for claims and expects to add to such reserves as appropriate.

The Railroad is also party to certain regulatory proceedings before the Surface
Transportation Board of the U.S. Department of Transportation (STB).  One
proceeding pertains to rail service problems in the western United States. As an
outgrowth of this proceeding, the STB has issued an emergency service order
imposing certain temporary measures on the Railroad designed, among other 
things, to reduce congestion on the Railroad's lines in the Houston, Texas 
area.  A second proceeding, initiated under the STB's continuing oversight 
jurisdiction with respect to the Corporation's acquisition of Southern Pacific 
and consolidation of Southern Pacific with UPRR (and separate from the STB's
regularly scheduled annual proceeding to review the implementation of the merger
and the effectiveness of the conditions that the STB imposed on it), is for the
purpose of considering the justification for and advisability of any proposals
for new remedial conditions to the merger as they pertain to service in the
Houston, Texas/Gulf Coast area, including proposals by Kansas City Southern
Railway Company (KCS), Texas Mexican Railway Company (Tex Mex) and the Greater
Houston Partnership (GHP) for the forced transfer by the Railroad to Tex Mex of
certain lines and facilities in and around Houston, the establishment of a
"neutral" switching operation in the greater Houston area, and the permanent
adoption of provisions in the STB's emergency service order that expanded Tex
Mex's right to handle traffic to and from Houston.  In addition, the STB has
initiated various inquiries and formal rulemaking proceedings regarding certain
elements of rail regulation following two days of hearings by the STB at the
request of two members of Congress and in response to shippers' expressions of
concern regarding railroad service quality, railroad rates and allegedly
inadequate regulatory remedies.  If the Railroad is unsuccessful in eliminating
the remaining congestion and service problems affecting its system, the STB 
could issue a new emergency service order upon the expiration of the current 
one and order the Railroad to take additional actions including, among other 
things, further diversions of traffic or the transfer of certain rail lines 
or other

16


facilities to other railroads.  In addition, there can be no assurance that the
proposals advanced by parties in the remedial conditions proceeding or the
proceedings initiated in response to the rail regulation hearings will not be
approved in some form.  Should the STB or Congress take aggressive action in the
rail regulation proceedings (e.g., by making purportedly competition-enhancing
changes in rate and route regulation and "access" provisions), the adverse 
effect on the Railroad and other rail carriers could be material.

The Corporation is also subject to Federal, state and local environmental laws
and regulations, and is currently participating in the investigation and
remediation of numerous sites.  Where the remediation costs can be reasonably
determined, and where such remediation is probable, the Corporation has recorded
a liability.  In addition, the Corporation and its subsidiaries periodically
enter into financial and other commitments and have retained certain contingent
liabilities upon the disposition of formerly-owned operations.
 
In addition, UPC and certain of its officers and directors are currently
defendants in two purported class action securities lawsuits, and certain 
current and former directors of the Corporation are currently defendants in 
a purported derivative action filed on behalf of the Corporation.  The class 
action suits allege, among other things, that management failed to disclose 
properly the Railroad's service and safety problems and thereby issued 
materially false and misleading statements concerning the merger with SP and 
the safe, efficient operation of its rail network.  The derivative action 
alleges, among other things, that the named current and former directors 
breached their fiduciary duties to the Corporation by approving the mergers 
of SP and Chicago and North Western Transportation Company into the 
Corporation without ensuring that the Corporation or the Railroad had 
adequate systems in place to effectively integrate those companies into the 
operations of the Corporation and the Railroad.  Because both the size of the 
class and the damages are uncertain, UPC and the Railroad are unable at this
time to determine the potential liability, if any, which might arise from 
these lawsuits.  Management believes that these claims are without merit and 
intends to defend them vigorously.

It is not possible at this time for the Corporation to fully determine the 
effect of all unasserted claims on its consolidated financial condition, 
results of operations or liquidity; 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.

successful in overcoming its congestion-related problems and implementing the
Plan and other operational and financial initiatives, industry competition and
regulatory developments, natural events such as floods and earthquakes, the
effects of adverse general economic conditions, fuel prices, labor strikes, the
impact of year 2000 systems problems and the ultimate outcome of shipper claims
related to congestion, environmental investigations or proceedings and other
types of claims and litigation.

Disclosure concerning market risk-sensitive instruments is set forth in Note 3
to the Financial Statements, pages 6-7 herein.


PART II.  OTHER INFORMATION


Item 1.  Legal Proceedings.

SOUTHERN PACIFIC ACQUISITION:  As previously reported in the Corporation's 1997
Annual Report on Form 10-K, various appeals have been filed with respect to the
STB's August 12, 1996 decision (the Decision) approving the acquisition of
control of Southern Pacific by the Corporation. All of the appeals have been
consolidated in the U.S. Court of Appeals for the District of Columbia Circuit.
Oral argument in the case is scheduled for September 11, 1998.  Various
appellants have withdrawn their appeals, leaving only Burlington Northern and
Santa Fe Railway Company (BNSF), the Western Coal Traffic League (WCTL),
Enterprise Products Company and the City of Reno, Nevada with appeals pending. 
On April 10, 1998, WCTL filed a motion to vacate and remand the Decision in 
light of a proceeding the STB commenced on March 31, 1998, under its continuing
oversight jurisdiction over the merger, to consider whether any additional
conditions are justified and should be imposed to deal with service problems in
the Houston/Gulf Coast area.  The STB, the Corporation and BNSF have opposed 
this motion.  The Corporation believes that it is unlikely that the disposition 
of the remaining appeals will have a material adverse impact on its consolidated
financial condition or its results of operations.

RAIL SERVICE PROCEEDINGS AND RELATED MATTERS:   As previously reported in the
Corporation's 1997 Annual Report on Form 10-K, the Railroad is currently subject
to an emergency service order issued by the STB on October 31, 1997, as an
outgrowth of a proceeding initiated by the STB on October 2, 1997 to investigate
rail service problems in the western United States.  The original service order,
which, among other things, imposed several temporary measures designed to reduce
congestion on the Railroad's lines in the Houston area, was modified and 
extended by a supplemental order dated December 4, 1997.  On February 25, 
1998, the STB, citing the gravity of the Railroad's congestion problems and 
characterizing them as "not yet close to being resolved," further modified 
the emergency service order and extended it until August 2, 1998, the 
maximum period allowable under

18

      
the law for the original order.  

On March 31, 1998, the STB initiated a proceeding under its continuing oversight
jurisdiction with respect to the merger of the Corporation and Southern Pacific
to consider proposals for new remedial conditions to the merger as they pertain
to service in the Houston, Texas/Gulf Coast area.  This proceeding, which is
separate from the STB's regularly scheduled annual proceeding to review the
implementation of the merger and the effectiveness of the conditions that the 
STB imposed on it, was initiated in response to submissions by Texas Mexican 
Railway Company (Tex Mex), Kansas City Southern Railway Company (KCS) and the 
Greater Houston Partnership (GHP), proposing that the Railroad be directed to 
transfer certain lines and facilities in the Gulf Coast region to other rail 
carriers, that a "neutral" switching operation be established in the greater 
Houston area and that provisions in the STB's emergency service order that 
expanded Tex Mex's right to handle traffic to and from Houston be adopted 
permanently.  The STB's decision announcing the proceeding established a 
procedural schedule for the submission of evidence, replies and rebuttal.

If continued implementation of the Plan and other operational and financial
initiatives undertaken by the Corporation ultimately prove unsuccessful in
alleviating the remaining congestion and related service problems experienced by
the Railroad, the STB could issue a new emergency service order upon the
expiration of the current one and order the Railroad to take additional actions
including, among other things, further diversions of traffic or the transfer of
certain of the Railroad's rail lines or other facilities to other railroads. In
addition, there can be no assurance that the proposals advanced by Tex Mex, KCS,
GHP or other parties in the remedial conditions proceeding will not be approved
in some form. 

RAIL ACCESS AND COMPETITION: Acting pursuant to requests from two members of
Congress and responding to shippers' concerns about railroad service quality,
railroad rates and allegedly inadequate regulatory remedies, the STB on April 
17, 1998, following two days of hearings, issued a decision opening inquiries 
into certain elements of rail regulation. The STB noted that no parties to the
hearings had shown how aggressive remedies designed to produce lower rates and
enhance competition would permit the industry to cover system costs and support
reinvestment.  Nevertheless, it (i) directed a panel of disinterested economic
experts to recommend appropriate standards to measure railroad revenue adequacy,
which is used to determine whether rates are lawful (this portion of the 
decision was subsequently modified to permit, as an alternative, discussions 
of this issue between railroad and shipper representatives); (ii) initiated 
a rulemaking proceeding to consider revisions to "competitive access" 
regulations in order to address quality of service issues; (iii) ordered 
interested parties to identify modifications to regulations governing access 
on non-service-related grounds; (iv) began a proceeding to consider 
eliminating product and geographic competition as factors to be considered in 
deciding whether a railroad has market dominance over rail traffic; 
(v) ordered large and small railroads to negotiate arrangements that would 
increase the role of short-line rail carriers; and (vi) directed the railroads 
to establish "formalized dialogue" immediately with large and small shippers 
and rail labor.  Should the STB or Congress take aggressive action, (e.g., by 
making purportedly competition-enhancing changes in rate and route regulation 
and "access" provisions), the adverse effect on the Railroad and other 
railroads could be material.

LABOR MATTERS:  As previously reported in the Corporation's 1997 Annual Report

19

on Form 10-K, the General Counsel of the National Labor Relations Board ("NLRB")
is seeking a bargaining order remedy in 15 cases involving Overnite where a
Teamsters local union lost a representation election.  These cases are pending
before the NLRB.  By decision dated April 10, 1998, an administrative law judge
has recommended that bargaining orders be issued in four locations.  Overnite
plans to appeal the decision to the NLRB.  The remaining cases must yet be
scheduled for trial.  A bargaining order remedy would require Overnite to
recognize and bargain with the union as if the union had won instead of lost the
election and would be warranted only if the following findings are made and
upheld: (1) the petitioning Teamsters local had obtained valid authorization
cards from a majority of the employees in an appropriate unit; (2) Overnite
committed serious unfair labor practices; and (3) those unfair labor practices
would preclude the holding of a fair election despite the application of less
drastic remedies.  Under NLRB case law, a bargaining order remedy would attach
retrospectively to the date when, after a union with a showing of majority
support demanded recognition, Overnite embarked on an unlawful course of 
conduct. In the event of such a retroactive effective bargaining order, 
Overnite would face back pay liability for losses in employee earnings due to 
unilateral changes in terms or conditions of employment, such as layoffs, 
reduced hours of work or less remunerative work assignments.  In addition, if 
a bargaining order remedy was granted in all contested cases, the increased 
Teamsters' representation could force Overnite to alter its posture in 
collective bargaining, increase its costs and alter its operating methods. 
Overnite believes it has substantial defenses to these cases and intends to 
continue to aggressively defend them.

ENVIRONMENTAL MATTERS: The Railroad has been named as a defendant in a civil
action brought by the California Department of Fish and Game, Office of Spill
Prevention and Response on April 10, 1998.  The complaint alleges violations of
California Fish and Game Code Section 5650, California Business and Professions
Code Section 17200, Civil Code Sections 3479 and 3480, and damage to the waters
of California for which the Department of Fish and Game allege trusteeship. The
complaint results from derailments and alleged releases of diesel fuel oil 
during 1995 in the Feather River Canyon in Butte County, California. The 
Complaint seeks penalties, exemplary damages, natural resource damages and 
unspecified injunctive relief.

The Railroad has been named as a defendant in a criminal misdemeanor action
brought by the State of California in the Municipal Court of Placer County,
California on February 24, 1998.  The complaint alleges a violation of 
California Fish and Game Code Section 5650 as a result of a diesel fuel spill 
in Norden, California in February 1997.  In addition, the California 
Department of Fish and Game is seeking penalties, monitoring costs and 
natural resource damages under state water statutes, and the U.S. 
Environmental Protection Agency (EPA) is seeking penalties for violation of 
the Clean Water Act in connection with the same incident.

The Railroad and Clean Harbors, a waste disposal firm, are the subject of a
criminal investigation by the EPA and the Federal Bureau of Investigation.  Tank
cars containing hazardous waste billed to Clean Harbors' transload facility in
Sterling, Colorado were held in the Railroad's Sterling, Colorado rail yard for
periods longer than ten days prior to placement in Clean Harbor's facility,
allegedly in violation of hazardous waste regulations.  A finding of violation
could result in significant criminal or civil penalties.

20


Item 2.  Changes in Securities and Use of Proceeds.

On April 1, 1998, Union Pacific Capital Trust (the "Trust"), a statutory 
business trust formed under the laws of the State of Delaware and a 
subsidiary of the Corporation, closed a private placement of $1.5 billion in 
aggregate amount of 6-1/4% Convertible Preferred Securities (the "Convertible 
Preferred Securities"), with a liquidation amount of $50 per each of the 
Convertible Preferred Securities.  Each of the Convertible Preferred Securities 
is convertible, at the option of the holder thereof, into shares of UPC's 
common stock, par value $2.50 per share (the "UPC Common Stock"), at the rate 
of 0.7257 shares of UPC Common Stock for each of the Convertible Preferred 
Securities, equivalent to a conversion price of $68.90 per share of UPC 
Common Stock, subject to adjustment under certain circumstances.  The 
Corporation owns all of the common securities of the Trust.

The initial purchasers of the Convertible Preferred Securities (the "Initial
Purchasers") were Credit Suisse First Boston Corporation; Merrill Lynch, Pierce,
Fenner & Smith Incorporated; Smith Barney Inc.; and Schroder & Co. Inc.  The
Initial Purchasers resold 29,909,600 of the Convertible Preferred Securities 
(the "QIB Securities") to qualified institutional buyers in reliance on 
Rule 144A under the Securities Act of 1933, as amended (the "Securities Act"), 
and 32,900 of the Convertible Preferred Securities (the "IAI Securities") to 
a limited number of institutional "accredited investors," as such term is 
defined in Rule 501(a)(1), (2), (3) or (7) under the Securities Act.  
The QIB Securities were sold for their liquidation amount of $50 each or 
$1,495,480,000 in the aggregate, and the IAI Securities were sold for their
liquidation amount of $50 each or $1,645,000 in the aggregate.  In connection 
with the purchase of the QIB Securities and the IAI Securities, the 
Corporation paid the Initial Purchasers a commission equal to 2.25% of the 
purchase price of each of the QIB Securities and the IAI Securities, or 
$33,648,300 and $37,012.50, respectively, in the aggregate.  In addition to 
sales of the QIB and IAI Securities, the initial purchasers also sold 57,500  
of the Convertible Preferred Securities outside the United States to certain 
persons other than U.S. persons in reliance on Regulation S under the 
Securities Act, as previously reported in the Corporation's Current Report on 
Form 8K, filed on April 20, 1998.
 
Item 4.  Submission of Matters to a Vote of Security Holders.

   (a) The annual meeting of shareholders of the Corporation was held on April
       17, 1998.

   (c) At the Annual Meeting, the Corporation's shareholders voted for the 
       election of Philip F. Anschutz (206,359,406 shares in favor;11,044,914 
       shares withheld), Robert P. Bauman (206,581,925 shares in favor; 
       10,822,395 shares withheld), Richard K. Davidson (205,913,479 shares in 
       favor; 11,490,841 shares withheld), Spencer F. Eccles (206,604,706 
       shares in favor; 10,799,614 shares withheld), Elbridge T. Gerry, Jr. 
       (206,601,620 shares in favor; 10,802,700 shares withheld), William H. 
       Gray, III (206,536,320 shares in favor; 10,868,000 shares withheld), 
       Judith Richards Hope (206,553,752 shares in favor; 10,850,568 shares 
       withheld), Richard J. Mahoney (206,564,904 shares in favor; 10,839,416 
       shares withheld), John R. Meyer (206,563,462 shares in favor; 10,840,858
       shares withheld), and Richard D. Simmons (206,586,280 shares in favor;
       10,818,040 shares withheld) as directors of the Corporation.  In 
       
21       

       addition, the Corporation's shareholders voted to ratify the appointment
       of Deloitte & Touche LLP as independent auditors of the Corporation  
       (215,978,952 shares in favor; 696,527 shares against;  728,841 shares  
       withheld).
