Item 1.01. Entry into a Material Definitive Agreement.

     On May 15, 2005, United Parcel Service, Inc. (the "Company") entered into
an Agreement of Merger ("Agreement of Merger") with Overnite Corporation
("Overnite") and Olympic Merger Sub, Inc., an indirect wholly owned subsidiary
of the Company ("Merger Sub"). The Agreement of Merger provides that, upon the
terms and subject to the conditions set forth in the Agreement of Merger, Merger
Sub will be merged with and into Overnite, with Overnite as the surviving
corporation of the merger (the "Merger"). As a result of the Merger, Overnite
will become an indirect wholly owned subsidiary of the Company, and each
outstanding share of Overnite common stock will be converted into the right to
receive $43.25 in cash, without interest thereon, for an aggregate purchase
price of approximately $1.25 billion.

     The Agreement of Merger contains customary representations, warranties and
covenants by each of the Company, Overnite and Merger Sub. Further, the closing
of the transaction is subject to Overnite shareholder and regulatory approval,
as well as other customary closing conditions. The transaction is expected to 
close in the third quarter of 2005.

     The foregoing description of the Agreement of Merger does not purport to be
complete and is qualified in its entirety by reference to the Agreement of
Merger, which is attached hereto as Exhibit 10.1.
