         NOTES TO INTERIM UNAUDITED CONDENSED FINANCIAL STATEMENTS
                 FOR THE SIX MONTHS ENDED DECEMBER 31, 1999

1.       INTRODUCTION

         CheckFree Management Corporation ("CheckFree Management") was formed
         from a plan of recapitalization of RCM Systems, Inc., a wholly owned
         subsidiary of CheckFree Holdings Corporation ("CheckFree Holdings"),
         on December 8, 1998. CheckFree Management was formed as a medical
         claims management subsidiary in order to appropriately minimize,
         control, and manage the medical claims liabilities of CheckFree
         Holdings and its subsidiaries.

         As of September 30, 1999, CheckFree Holdings and its subsidiaries owned
         approximately 63% of CheckFree Management. On November 19, 1999,
         CheckFree Corporation, a wholly owned subsidiary of CheckFree Holdings,
         purchased all outstanding shares of Class D Preferred Stock. Subsequent
         to this purchase, CheckFree Holdings and its subsidiaries own 89% of
         the Company.

         The accompanying condensed consolidated financial statements and notes
         thereto have been prepared in accordance with the rules and regulations
         of the Securities and Exchange Commission for Form 10-Q and include all
         of the information and disclosures required by generally accepted
         accounting principles for interim financial reporting. The results of
         operations for the six months ended December 31, 1999 are not
         necessarily indicative of the results for the full year.

         These financial statements should be read in conjunction with the
         financial statements, accounting policies and financial notes thereto
         of CheckFree Management included within CheckFree Holdings Corporation
         and Subsidiaries Annual Report filed with the Securities and Exchange
         Commission on Form 10-K/A. In the opinion of management, the
         accompanying condensed consolidated unaudited financial statements
         reflect all adjustments (consisting only of normal recurring
         adjustments) which are necessary for a fair representation of
         financial results for the interim periods presented.

2.       RECENT ACCOUNTING PRONOUNCEMENTS

         In June 1998 the Financial Accounting Standards Board issued SFAS 133,
         "Accounting for Derivative Instruments and Hedging Activities," which
         will require that all derivative financial instruments be recognized as
         either assets or liabilities in the balance sheet. SFAS 133 will be
         effective for the Company's first quarter of fiscal 2001. The Company's
         current investment policy does not allow for the use of hedging
         instruments. In anticipation of the adoption of SFAS 133, the Company
         is currently reviewing all outstanding contracts for evidence of
         embedded derivative. Based on the procedures undertaken through this
         point, management does not believe that adoption of SFAS 133 will have
         a material impact on its results of operations.
