ITEM 5.  OTHER EVENTS.

     On March 24, 1999, Concentra Managed Care, Inc., a Delaware corporation 
("Concentra"), entered into an Amended and Restated Agreement and Plan of 
Merger (the "Amended Merger Agreement") with Yankee Acquisition Corp., a 
Delaware corporation ("Newco"), amending the Agreement and Plan of Merger 
previously entered into between Concentra and Yankee on March 2, 1999. The 
Amended Merger Agreement contemplates the merger (the "Merger") of Newco with 
and into Concentra.  As a result of the Merger, each outstanding share of 
Concentra's common stock, par value $.01 per share (the "Concentra Common 
Stock"), (other than shares held by stockholders who exercise and perfect 
their dissenters' appraisal rights) will be converted into the right to 
receive $16.50 in cash. Shares held by Concentra, its subsidiaries or Yankee 
or its affiliates will be cancelled in the Merger.

     The Merger is conditioned upon, among other things, approval of the 
stockholders of Concentra, receipt of financing and upon certain regulatory 
approvals.  A copy of the Amended Merger Agreement is attached as an exhibit 
hereto and is incorporated herein by reference in its entirety.

     A copy of the press release issued by Concentra announcing the execution 
of the Amended Merger Agreement is attached as an exhibit hereto and is 
incorporated herein by reference in its entirety.
