                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS



To the Administrative Committee of the
ServiceMaster Employee Share Purchase Plan:

We have audited the accompanying  statements of net assets of the  ServiceMaster
Employee  Share  Purchase Plan as of December 31, 1998 and 1997, and the related
statements  of changes  in net assets for each of the three  years in the period
ended December 31, 1998. These financial  statements are the  responsibility  of
the Plan's Administrative Committee. Our responsibility is to express an opinion
on these financial statements based on our audits.

We  conducted  our  audits  in  accordance  with  generally   accepted  auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements.  An audit also includes
assessing the  accounting  principles  used and  significant  estimates  made by
management,  as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion,  the financial  statements  referred to above present fairly, in
all  material  respects,  the net assets of the Plan as of December 31, 1998 and
1997 and the  changes in net  assets  for each of the three  years in the period
ended  December  31,  1998 in  conformity  with  generally  accepted  accounting
principles.

                          NOTES TO FINANCIAL STATEMENTS


1.   The Plan

     The ServiceMaster  Employee Share Purchase Plan (the "Plan") was created to
     give eligible employees, wishing to do so, a convenient means of purchasing
     The  ServiceMaster  Company  shares  through  payroll  deductions  and cash
     contributions,  supplemented  by  contributions  made by The  ServiceMaster
     Company ("ServiceMaster").  Employees of ServiceMaster or any subsidiary or
     affiliate  which  has  adopted  the Plan on  behalf  of its  employees  who
     regularly  work nine  months or more  during the year,  who have an average
     work  week of 32  hours  or more  during  the  period  worked  and who have
     attained  age 18 are  eligible  to  participate  in the  Plan on the  first
     business day of the calendar  quarter  coinciding with or subsequent to the
     first  anniversary  of their  employment.  As of December 31,  1998,  7,738
     employees were participating in the Plan.

     Details relating to shares issued by the Plan (reflecting all share splits)
     from inception (July 1, 1972) through December 31, 1998, are as follows:



     
                                                                 Number
                                                                of Shares          Total Cost 
                                                              -------------       -------------

                                                                                
                  Issued during the year ended
                     December 31, 1998 to participants              496,865       $   9,576,524
                  Issued from inception through

                  Total issued from inception through
                     December 31, 1998                           30,123,856       $  87,349,870

2.   Summary of Significant Accounting Policies

(a)      The transactions of the Plan are accounted for on the accrual basis of 
         accounting.

(b)      Expenses incurred by the Plan are paid by ServiceMaster.

(c)      The  preparation  of  the  Plan's  financial  statements  requires  the
      Administrative  Committee  to  make  certain  estimates  and   assumptions
      required  under  generally   accepted   accounting   principles  which may
      differ from actual results.

3.   Contributions

     The amounts contributed by the participants and ServiceMaster  during 1998,
     1997, and 1996 were as follows:



                                            1998                         1997                           1996
                                       Contributed by                 Contributed by               Contributed by    
                                 Participants   ServiceMaster   Participants  ServiceMaster   Participants  ServiceMaster
                                 ------------   -------------   ------------  -------------   ------------  ------------- 
                                                                                           
     Participant contributions
       and ServiceMaster
       required contributions
       for the year              $   8,311,040  $    37,500     $  7,299,615  $     37,500     $  6,321,820  $    37,500

     ServiceMaster additional
       contributions                   -          1,209,156           -          1,057,442           -           910,773
                                 -------------  -----------     ------------  ------------     ------------  -----------

     Total contributions         $   8,311,040  $ 1,246,656     $  7,299,615  $  1,094,942     $  6,321,820  $   948,273
                                 =============  ===========     ============  ============     ============  ===========


     Participant  contributions  and required  ServiceMaster  contributions  are
     accounted for on the accrual basis. The  ServiceMaster  contribution to the
     Plan is equal to the lesser of 15% of total  participant  contributions  or
     $37,500.  ServiceMaster  may elect to make additional  contributions to the
     Plan as it deems appropriate.  Participants may contribute a maximum of 10%
     of their prior year compensation as defined in the Plan agreement.

     The Board of Directors of ServiceMaster  approved additional  contributions
     which, together with the required  ServiceMaster  contributions  previously
     made, were  equivalent to a 15% matching of the  participant  contributions
     made during 1998, 1997, and 1996, for participants as of each year end.


4.   Federal Income Taxes

     (a)   Tax Status of the Plan - The Plan's  trust does not  qualify  for tax
           exempt  status  under  Section  501 of  the  Internal  Revenue  Code.
           However,  the Plan incurs no tax  liability  since all Plan income is
           distributed to the participants.

     (b)   Tax Status of Each  Participant  - Since the Plan does not qualify as
           an "employee  stock  purchase plan" under Section 423 of the Internal
           Revenue Code (the  "Code") or as a "stock  bonus plan" under  Section
           401 of the Code, the  participant  realizes income equal to his share
           of the ServiceMaster  contributions and cash  distributions on shares
           issued to the participant during the calendar year.
