                                     PART I

Item 1.  Business.

(a)  Yellow Corporation and its wholly-owned subsidiaries are collectively
     referred to as "the company". The company provides transportation services
     primarily to the less-than-truckload (LTL) market throughout North America
     and, through partnership alliances, other international markets. During
     1998, the company concentrated on improving future earnings growth through
     the negotiation of a new five-year National Master Freight Agreement (NMFA)
     at its Yellow Freight subsidiary, divesting of its under performing Preston
     Trucking subsidiary and the acquisition of Action Express, Inc., a Pacific
     Northwest regional LTL transportation company, as well as reducing
     outstanding shares of common stock through stock buyback programs.

(b)  The company provides interstate transportation of general commodity
     freight, primarily LTL, primarily by motor vehicle. The operation of the
     company is conducted among two primary business segments. Financial
     disclosures for these segments are presented in the Business Segments
     footnote on page 43 of the 1998 Annual Report to Shareholders which is
     incorporated herein by reference.

(c)  Yellow Corporation is a holding company providing freight transportation 
     services through its subsidiaries, Yellow Freight System, Inc. (Yellow
     Freight), Saia Motor Freight Line, Inc. (Saia), WestEx, Inc. (WestEx), and
     Action Express, Inc. (Action). Yellow Services, Inc. (Yellow Services) is a
     subsidiary that provides information technology services to the company and
     its subsidiaries. The company employed an average of 29,700 persons in
     1998.

     Yellow Freight, the company's principal subsidiary based in Overland Park,
     Kansas, accounted for 86% of total company revenue from continuing
     operations in 1998, 88% in 1997 and 89% in 1996. It is one of the nation's
     largest providers of LTL transportation services. It provides comprehensive
     national LTL service as well as international service to Mexico, Canada
     and, via alliances, Europe, the Asia/Pacific region, South America and
     Central America.

     Saia is a regional LTL carrier headquartered in a suburb of Atlanta,
     Georgia provides overnight and second-day service in eleven southeastern
     states and Puerto Rico. Saia accounted for 12% of total company revenue
     from continuing operations in 1998, 11% in 1997 and 10% in 1996.

     WestEx provides one and two-day service in Arizona, California, Nevada, New
     Mexico, and Texas. WestEx had operating revenue of $65 million in 1998 and
     is headquartered in Phoenix, Arizona.

     Action provides one and two day service to the Pacific Northwest and Rocky
     Mountain states. Action was acquired on December 1, 1998 and is
     headquartered in Boise, Idaho. Only revenue since its acquisition date is
     included in the results of operations and was not material to the 1998
     consolidated financial results of the company.

Item 1. Business. (cont.)

     Yellow Services supports the company's subsidiaries - primarily Yellow
     Freight - with information technology. Its headquarters is in Overland
     Park, Kansas.

     The operations of the freight transportation companies are partially
     regulated by the United States Department of Transportation and state
     regulatory bodies. The company's competition includes contract motor
     carriers, private fleets, railroads, other motor carriers and small
     shipment carriers. No single carrier has a dominant share of the motor
     freight market.

     The company operates in a highly price-sensitive and competitive industry,
     making pricing, customer service, effective asset utilization, and cost
     control major competitive factors. No single customer accounts for more
     than 10% of the company's total revenue. The company's revenue is subject
     to seasonal variations throughout the year. The first quarter is generally
     the weakest while the third is the strongest.

     Operating revenue for Yellow Corporation (the company) totaled $2.9 billion
     in 1998, relatively unchanged from 1997. Operating income for the year was
     $83.4 million, down from $98.7 million in 1997. Income from continuing
     operations was $40.1 million or $1.49 per share (diluted) in 1998, compared
     to $52.7 million or $1.84 per share (diluted) in 1997.

     Yellow Freight's 1998 operating income of $66.9 million was lower than 1997
     operating income of $82.7 million. Operating revenue was $2.49 billion for
     1998, down 1.8 percent from $2.54 billion for 1997. The 1998 operating
     ratio was 97.3 compare with 96.7 in 1997.

     Saia continued its growth with 1998 operating income of $24.7 million, up
     from $19.6 million in 1997. Saia's 1998 operating ratio was 92.7 compared
     with 93.7 in 1997.

     WestEx continued its rapid growth in 1998, reporting revenue of 64.9
     million, up 32.4 percent from 49.0 million in 1997.

     The company's operations are further described in Management's Discussion
     and Analysis on page 17 of the 1998 Annual Report to Shareholders, which is
     incorporated herein by reference.

     Discontinued Operations

     In the second quarter of 1998, the company sold Preston Trucking Company,
     Inc. (Preston Trucking) its northeast regional LTL segment to a management
     group of three senior officers of Preston Trucking. The sale resulted in a
     charge of $63.6 million net of anticipated tax benefits of approximately
     $28.0 million, which has been reflected as discontinued operations in the
     consolidated statement of operations.

     After giving effect to the discontinued operations, the company recorded a
     net loss for 1998 of $28.7 million or $1.06 per share (diluted), versus net
     income of $52.4 million, or $1.83 per share (diluted) in 1997.

Item 1. Business. (cont.)

     The company's liquidity needs arise primarily from capital investment in
     new equipment, land and structures and information technology, as well as
     funding working capital requirements. Working capital decreased from a
     negative $22 million at year-end 1997 to a negative $42 million at year-end
     1998. The company can operate with negative working capital because of the
     quick turnover of its account receivables and its ready access to sources
     of short-term liquidity.

     Future Outlook

     The company operates in a highly competitive and changing transportation
     business. The 1998 five-year NMFA labor agreement provides stability to the
     customers of its largest subsidiary, Yellow Freight with reasonable
     economic terms for its largest expense item.

     All of the company's subsidiaries can now focus on achieving profitable
     revenue growth. This starts with continuous improvement focus on offering
     best in class customer satisfaction for core services. It also means
     reinventing the business with more customer solutions involving new and
     enhanced services, not limited to just LTL. An example of this is Yellow
     Freight's introduction in July of Exact Express, a time-definite, expedited
     air and ground delivery service.

     The company's subsidiaries are also working to continuously improve their
     productivity and cost efficiency to best in class levels. This not only
     reduces costs, but it also supports improved customer service capabilities.

     The company believes its ability to achieve profitable revenue growth and
     cost efficiency is enhanced by its technology investments, its
     comprehensive physical assets as well as the quality and low turnover of
     its experienced work force. Because employees are the company's greatest
     asset, the subsidiaries are focused on achieving best in class safety
     performance.

     In addition to current subsidiaries and businesses, the company will also
     evaluate opportunities to grow earnings through acquisitions. Management
     believes the company's balance sheet and access to capital provide
     flexibility to reinvest in existing businesses as well as new opportunities
     with attractive growth prospects.

     Statements contained herein, that are not purely historical, are forward
     looking statements within the meaning of the Private Securities Litigation
     Reform Act of 1995, including statements regarding the company's
     expectations, hopes, beliefs and intentions on strategies regarding the
     future. It is important to note that the company's actual future results
     could differ materially from those projected in such forward-looking
     statements because of a number of factors, including but not limited to
     inflation, labor relations, inclement weather, competitor pricing activity,
     year 2000 issues, expense volatility and a downturn in general economic
     activity.

Item 1. Business. (cont.)

(d)  Revenue from foreign sources is discussed in the Business Segments footnote
     on page 44 of the 1998 Annual Report to Shareholders, which is incorporated
     herein by reference. Foreign source revenue was not material to
     consolidated financial results in 1998, 1997 and 1996.

Item 2.  Properties.

The company's operating subsidiaries each provide their transportation services
through separate networks, principally consisting of a fleet of tractors and
trailers and real estate terminal facilities.

At December 31, 1998, the company operated a total of 505 freight terminals
located in 50 states, Puerto Rico, parts of Canada and Mexico. Of this total,
238 were owned terminals and 267 were leased, generally for terms of three years
or less. The number of vehicle back-in doors totaled 15,997, of which 12,111
were at owned terminals and 3,886 were at leased terminals. The freight
terminals vary in size ranging from one to three doors at small local terminals,
to over 300 doors at Yellow Freight's largest consolidation and distribution
terminal. Substantially all of the larger terminals, containing the greatest
number of doors, are owned. In addition, the company and most of its
subsidiaries own and occupy general office buildings in their headquarters city.

At December 31, 1998, the company's subsidiaries operated the following number
of linehaul units: tractors - 4,201, and trailers - 36,459. The company operated
the following number of city units: trucks and tractors - 6,738 and trailers -
6,621.

The company's facilitates and equipment are adequate to meet current business
requirements. The company expects moderate growth in 1999 and has projected only
modest increases in its operational capacity. Projected net capital expenditures
for 1999 are $147 million, an increase over $96 million in 1998 net capital
expenditures. Net capital for both periods pertain primarily to replacement of
revenue equipment at all subsidiaries, growth capital at Saia, WestEx and
Action, and additional investments in information technology.

                          Report of Independent Public
                   Accountants on Financial Statement Schedule



To the Shareholders of Yellow Corporation:

We have audited in accordance with generally accepted auditing standards, the
consolidated financial statements included in Yellow Corporation and
Subsidiaries' annual report to shareholders incorporated by reference in this
Form 10-K, and have issued our report thereon dated January 28, 1999. Our audit
was made for the purpose of forming an opinion on those statements taken as a
whole. The schedule of valuation and qualifying accounts (Schedule II) is the
responsibility of the company's management and is presented for purposes of
complying with the Securities and Exchange Commission's rules and is not part of
the basic consolidated financial statements. This schedule has been subjected to
the auditing procedures applied in the audit of the basic consolidated financial
statements and, in our opinion, fairly states in all material respects the
financial data required to be set forth therein in relation to the basic
consolidated financial statements taken as a whole.
