                              EIGHTH AMENDMENT TO
                        NON-QUALIFIED STOCK OPTION PLAN
                      FOR EMPLOYEES OF ACQUIRED COMPANIES


         THIS EIGHTH AMENDMENT (the "Eighth Amendment") is made effective as of
the 20th day of January, 2000, by PER-SE TECHNOLOGIES, INC., a Delaware
corporation formerly known as Medaphis Corporation (the "Company").

                              W I T N E S S E T H:

         WHEREAS, the Company has previously adopted the Medaphis Corporation
Non-Qualified Stock Option Plan for Employees of Acquired Companies, as amended
(the "Plan"); and

         WHEREAS, the Compensation Committee of the Board of Directors of the
Company has duly authorized an amendment of the Plan to reflect the recent name
change of the Company, and to decrease the number of shares available for grant
pursuant to the Plan from 1,505,000 shares (as adjusted to reflect a
one-for-three reverse stock split effective November 23, 1999) to 1,320,000
shares.

         NOW, THEREFORE, the Plan is hereby amended by deleting the name
"Medaphis Corporation" from the Plan and replacing such name with the name
"Per-Se Technologies, Inc."

         FURTHER, Section 3 of the Plan is hereby amended by deleting Section 3
of the Plan in its entirety and replacing it with the following:

                                     "ss. 3

                         SHARES RESERVED UNDER THE PLAN

         There shall be 1,320,000 shares of Stock reserved for issuance under
         this Plan, and such shares of Stock shall be reserved to the extent
         that the Company deems appropriate from authorized but unissued shares
         of Stock and from shares of Stock which have been repurchased by the
         Company. Furthermore, any shares of Stock subject to an Option that
         remain unissued after the cancellation or expiration of such Option
         thereafter shall again become available for use under this Plan."


         FURTHER, except as specifically amended by this Eighth Amendment, the
Plan shall remain in full force and effect as prior to this Eighth Amendment.


   2

         IN WITNESS WHEREOF, the Company has caused this Eighth Amendment to be
executed on the day and year first above written.


                                   PER-SE TECHNOLOGIES, INC.
