ITEM 2. ACQUISITION OR DISPOSITION OF ASSETS.

(a)  On April 27, 1999, ProBusiness Services, Inc.,  a Delaware corporation
     ("ProBusiness"), entered into an Agreement and Plan of Reorganization (the
     "Agreement") with certain parties, including Clemco, Inc. ("Conduit
     Parent"), a privately-held Georgia corporation and the parent and sole
     stockholder of Conduit Software, Inc. ("Conduit"), a privately-held Georgia
     corporation and a leading provider of Employee Relationship Management
     applications.

     Pursuant to the Agreement and as of the date of the Agreement, ProBusiness
     issued 1,714,957 shares of its common stock to Conduit Parent's
     stockholders in exchange for all of the outstanding capital stock of
     Conduit Parent, and all outstanding options and warrants to purchase
     Conduit Parent's capital stock were converted into options and warrants to
     purchase 82,997 shares of ProBusiness common stock.  The consideration
     issued by ProBusiness was determined as a result of arm's length
     negotiations between senior management of ProBusiness and Conduit.

     The foregoing description does not purport to be a complete description of
     the terms of the acquisition agreement, a copy of which is attached hereto
     as an exhibit and incorporated by reference.  

(b)  Certain of the assets of Conduit constitute plant, equipment and other
     physical property, particularly furniture, fixtures and leasehold
     improvements used in the business of Conduit, and ProBusiness intends to
     continue such use.
     
ITEM 7. FINANCIAL STATEMENTS AND EXHIBITS.

(a)  Financial statements of business acquired.  It is impracticable at this
     time for the Registrants to provide the financial statements of the
     acquired business.  Such financial statements will be filed by the 
     Registrant as an amendment to this Form 8-K as soon as practicable, but, in
     any event, not later than sixty days after the date hereof. 

(b)  Pro forma financial information.  It is impracticable at this time for the 
     Registrant to provide the pro forma financial information relative to the
     acquired business.  Such pro forma financial information will be filed by
     the  Registrant as amendment to this Form 8-K as soon as practicable, but,
