                                     Preface

         Reference is made to the Rights Agreement dated as of February 11,
1999, by and between Per-Se (then known as Medaphis Corporation) and the Rights
Agent (the "Rights Agreement"), as amended by (i) the First Amendment thereto
dated as of May 4, 2000, and (ii) the Second Amendment thereto dated as of
December 6, 2001 and effective as of March 6, 2002 (the Rights Agreement, as
amended by the First and Second Amendments thereto, the "Agreement").
Capitalized terms used herein and not otherwise defined shall have the same

         The Agreement provides for the dividend distribution of one Right for

representing the right to purchase one one-hundredth of a share of Series A
Junior Participating Preferred Stock. Certain events are triggered under the
Agreement upon any person becoming an "Acquiring Person," as defined in Section
1(a) of the Agreement. Section 27(a) of the Agreement provides for the amendment
or modification of the Agreement, and Per-Se desires to amend the Agreement
pursuant to Section 27(a) thereof to provide for an additional exclusion from
the definition of the term "Acquired Person."
