Item 1.01 Entry into a Material Definitive Agreement

     On October 13, 2004, First Health Group Corp. (“First Health”) entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Coventry Health Care, Inc. (“Coventry”), pursuant to which First Health will merge with and into a wholly owned subsidiary of Coventry (the “Merger”). The Merger Agreement and the press release announcing the Merger were attached as exhibits to the Current Report on Form 8-K filed by First Health with the Securities and Exchange Commission on October 14, 2004.

     In connection with the Merger Agreement, First Health will commence an offer to purchase all of the outstanding options, whether or not vested, to purchase shares of First Health common stock (the “Option Tender Offer”). Upon consummation of the Option Tender Offer, First Health will pay cash to the holder of each validly tendered option in an amount for each option equal to the greater of (i) the amount by which $18.75 exceeds the exercise price of the option, if any, or (ii) $1.25, in each case less any applicable withholdings for taxes. The Option Tender Offer will be conditioned upon, among other things, satisfaction or waiver of all the conditions to the Merger set forth in the Merger Agreement. On or since October 13, 2004, certain holders of outstanding options to purchase shares of First Health common stock entered into agreements to, among other things, tender their options pursuant to the Option Tender Offer (the “Options Tender Agreement”).
