Item 2.

On March 1, 2004, the Company completed its acquisition, effective as of the
close of business on February 29, 2004 (the "Closing") of 36 leased automotive
repair and tire retail locations in the Baltimore, Maryland and Arlington,
Virginia areas from Mr. Tire, Inc. (the "Seller") and its sole shareholder,
Atlantic Automotive Corp. (doing business as Mile One Automotive) ("Atlantic").
The acquired locations include 26 retail stores and 10 kiosks, which operate in
Mile One Automotive dealerships. In total, these locations produced
approximately $50 million in revenue in the year ending December 2003. Pursuant
to the terms of an Asset Purchase Agreement, dated as of February 9, 2004, by
and among the Company, the Seller and Atlantic (the "Purchase Agreement"), the
Company purchased certain of Seller's assets, including inventory, fixed assets
and intellectual property. The Company intends to continue to utilize the
acquired assets to operate the Mr. Tire locations. The Company also assumed
certain of Seller's liabilities, including Seller's obligations pursuant to the
real property leases for each of the twenty-six (26) retail store locations,
certain warranty obligations outstanding to customers as of the Closing and
certain other liabilities. The transaction is valued at approximately $29
million (cash, Warrant (as defined herein) and assumed liabilities).

As part of the purchase price paid by the Company pursuant to the Purchase
Agreement at the Closing, the Company transferred $24.3 million to Seller and $1
million to an escrow account to cover certain post-closing adjustments to the
Purchase Price and indemnification obligations of Seller and Atlantic (the
"Purchase Price"). The Purchase Price will be adjusted post-closing to reflect,
among other things, final counts of inventory and fixed assets. Also as part of
the Purchase Price, at the Closing the Company issued a two-year warrant
agreement (the "Warrant") to Atlantic, pursuant to which Atlantic may purchase
100,000 shares (the "Shares") of the Company's $.01 par value Common Stock at
$22.33 per share, the closing price of the Company's Common Stock on
February 6, 2004. Atlantic may not exercise the Warrant for a


                                       2

period of six months after the Closing or until September 1, 2004 and the
Company has agreed to use its best efforts to submit all required information
and filings with the Securities and Exchange Commission in order to register the
Shares. The Company financed the cash portion of the Purchase Price with bank
debt under the Company's existing revolving credit facility.

Prior to the completion of the acquisition, the Company, Seller and Atlantic
agreed to amend the Purchase Agreement, in order to, among other things, revise
certain Schedules to the Purchase Agreement and amend the indemnification
provisions of the Purchase Agreement. The Asset Purchase Agreement has been
filed as Exhibit 10.1 to this Form 8-K. The First Amendment to Asset Purchase
Agreement has been filed as Exhibit 10.2 to this Form 8-K.
