Actual results could differ materially from these expectations depending on factors such as the combined company's cost of capital, the ability of the combined company to identify and implement cost savings, synergies and efficiencies in the time frame needed to achieve these expectations, prior contractual commitments of the combined companies and their ability to terminate these commitments or amend, renegotiate or settle the same, the combined company's actual expenditures, any unforeseen merger or acquisition opportunities that could affect capital needs, the costs incurred in implementing synergies and the factors that generally affect both Yellow's and Roadway's respective businesses as further outlined in "Management's Discussion and Analysis of Financial Condition and Results of Operations" in each of the companies' respective Annual Reports on Form 10-K for the year ended December 31, 2002 and the "Risk Factors" outlined in Yellow's Current Report on Form 8-K filed on August 4, 2003 and its Registration Statement on Form S-4, as amended, filed on October 17, 2003.

Actual actions that the combined company may take may differ from time to time as the combined company may deem necessary or advisable in the best interest of the combined company and its shareholders to attempt to achieve the successful integration of the companies, the synergies needed to make the transaction a financial success and to react to the economy and the combined company's market for its transportation services.
