ITEM 1. CHANGES IN CONTROL OF REGISTRANT

         On June 12, 1999, the Registrant entered into an Agreement and Plan of
Merger (the "Merger Agreement") by and among the Registrant, Stagecoach Holdings
plc, a public limited company organized under the laws of Scotland ("Parent"),
SCH Holdings Corp., a Delaware corporation and wholly owned subsidiary of Parent
("Purchaser"), and SCH Acquisition Corp., a Delaware corporation and wholly
owned subsidiary of Purchaser ("Merger Sub"). On July 26, 1999, upon
consummation of a tender offer made by it in accordance with the Merger
Agreement, approximately 25,177,547 shares of the Registrant's outstanding
common stock, par value $0.01 per share (the "Shares") had been tendered out of
25,988,178, including approximately 1,077,920 shares tendered by guaranteed
delivery. The tender offer was followed by a merger on July 26, 1999 of
Registrant into Purchaser, in which the remaining Shares outstanding were
converted into the right to receive $42.00 in cash per share, without interest
thereon, and the surviving corporation became a wholly owned subsidiary of
Parent. Following the merger, the shares of the surviving corporation were
deposited in one of several independent voting trusts pending approval by the
Surface Transportation Board of the acquisition of control by Parent of the
Registrant.

         Purchaser's Offer to Purchase dated June 18, 1999 (the "Offer to
Purchase") is attached hereto as Exhibit 99.0. The disclosure contained in the
Introduction, Section 9 ("Sources and Amount of Funds"), Section 11 ("The Merger
Agreement and Other Agreements") and Section 12 ("Purpose of the Offer; the
Merger; Plans for the Company") is incorporated herein by this reference.

         Immediately following the filing of this Report, the Registrant is
filing a report on Form 15 with the Securities and Exchange Commission, thereby
suspending its duty to file reports under Sections 13 and 15(d) of the
Securities Exchange Act of 1934, as amended, in accordance with Rule
12h-3(b)(1)(i) thereunder.

ITEM 5.  OTHER EVENTS

         In connection with and prior to the consummation of the tender offer
and the merger, Registrant, the Purchaser, the entities listed on Schedule A
thereto (the "Guarantors") and The Bank of New York, as trustee (the "Trustee")
executed the First Supplemental Indenture, dated as of July 23, 1999, to the
Indenture, dated as of June 24, 1998 (the "Indenture"), among the Registrant,
the Guarantors and the Trustee, to provide for the Purchaser to assume all
obligations of the Registrant under the 9 3/8% Series A Senior Subordinated
Notes due 2007 (the "Series A Notes") and the 9 3/8% Series B Senior
Subordinated Notes due 2007 (the "Series B Notes" and, together with the Series
A Notes, the "Notes"). The First Supplemental Indenture is attached hereto as
Exhibit 99.1.

         In connection with and prior to the consummation of the tender offer
and the merger, Registrant also entered into a Credit Agreement (the "Credit
Agreement), dated July 24, 1999, with SCH US Holdings Corp., a Delaware
corporation and wholly owned subsidiary of Parent (the "Lender"). The Credit
Agreement provides, among other things, for the Lender to provide a $600





<PAGE>   3
million revolving credit loan facility to the Registrant (the "Credit Facility")
in order to refinance certain of the Registrant's existing indebtedness, provide
funds for certain expenses of the Registrant in connection with the tender offer
and the merger, and to provide working capital following the merger. Pursuant to
the terms of the Credit Agreement, the Credit Facility is subordinated to the
Notes.
