                        SERVICEMASTER LIMITED PARTNERSHIP
                        (A Delaware Limited Partnership)


                      SERVICEMASTER ACQUISITION CORPORATION
                            (A Delaware Corporation)


                                       and


                                  BAREFOOT INC.
                            (A Delaware Corporation)





                                December 5, 1996

                          PLAN AND AGREEMENT OF MERGER

     This PLAN AND AGREEMENT OF MERGER, dated as of December 5, 1996, is entered
into  by  and  among  ServiceMaster  Limited  Partnership  ("ServiceMaster"),  a
Delaware limited Partnership, ServiceMaster Acquisition Corporation (the "Merger
Sub"),  a  Delaware   corporation  and  wholly-owned   indirect   subsidiary  of
ServiceMaster and Barefoot Inc. ("Barefoot"), a Delaware corporation.

                                    RECITALS

     Simultaneous with the execution of this Agreement,  the parties hereto have
entered into an Acquisition  Agreement  which provides  subject to the terms and
conditions  specified therein that  ServiceMaster  will make a tender offer (the
"Offer")  for all of the  issued and  outstanding  shares of  Barefoot  in which
ServiceMaster  will pay the  Offer  Consideration  (as  defined  in  Acquisition
Agreement) for each Share  tendered.  The term "Share" as used in this Agreement
means  a  share  of  Barefoot's   common  stock  as  constituted  prior  to  the
consummation of the Merger provided for by this Agreement.

     The respective boards of directors of ServiceMaster, MergerSub and Barefoot
have  determined  that it is advisable  for MergerSub to be merged with and into
Barefoot (the "Merger") on the terms prescribed in this Agreement. The Merger is
intended to (i)  convert all Shares not  tendered in the Offer into an amount of
cash (herein called the "Merger Price") exactly equal to the Cash  Consideration
paid under the  Acquisition  Agreement  for the Shares  acquired by means of the
Offer and (ii) convert Barefoot into a wholly-owned subsidiary of ServiceMaster.
The parties have entered into this Agreement to prescribe  terms for the Merger.
Each term  which is  defined  in the  Acquisition  Agreement  and is not given a
different  meaning in this  Agreement has the same meaning in this  Agreement as
the term is given in the Acquisition Agreement.


                                    ARTICLE I
                                   The Merger

     1.1 The  Merger.  At the  Effective  Time (as defined in Section  1.3),  in
accordance  with this  Agreement and the Delaware  General  Corporation  Law, as
amended (the "Delaware Law"),  MergerSub shall be merged with and into Barefoot,
the separate  existence of MergerSub (except as may be continued by operation of
law) shall cease,  and Barefoot  shall  continue as the  surviving  corporation.
Barefoot,  in its  capacity  as the  surviving  corporation  in the  Merger,  is
hereinafter sometimes referred to as the "Surviving  Corporation."  Barefoot and
MergerSub  are  sometimes   referred  to   collectively   as  the   "Constituent
Corporations", or individually as a "Constituent Corporation."

     1.2 Effect of the Merger. The Surviving  Corporation shall at and after the
Effective Time possess all the rights,  privileges,  immunities, and franchises,
as well of a public and of a private nature, of the Constituent Corporations and
all property,  real,  personal and mixed, and all debts due on whatever account,
and all other causes of action,  and all and every other interest,  or belonging

                                      -58-



to or due to each of the Constituent Corporations,  shall be taken and deemed to
be transferred to and vested in the Surviving Corporation without further act or
deed, and the title to any real estate, or any interest  thereto,  vested in any
of the Constituent  Corporations,  shall not revert or be in any way impaired by
reason  of the  Merger;  and  the  Surviving  Corporation  shall  henceforth  be
responsible  and liable for all the  obligations  and liabilities of each of the
Constituent Corporations, and any claim existing or action or proceeding pending
by or against any of the Constituent  Corporations may be prosecuted to judgment
as if the  Merger  had not taken  place,  or the  Surviving  Corporation  may be
substituted in its place, all with the effect set forth in Sections 259, 260 and
261 of the  Delaware  Law. The  authority  of the  officers of  MergerSub  shall
continue  with  respect to the due  execution  thereof or  conveyance  and other
documents  where the execution  thereof is required or convenient to comply with
any  provision of the Delaware  Law, of any  contract to which  MergerSub  was a
party or the plan of merger contained herein.

     1.3  Effective  Time.  As  soon  as is  reasonably  practicable  after  the
stockholders  of Barefoot have approved the Merger or  ServiceMaster  shall have
acquired at least 90% of then outstanding  Shares (whichever shall first occur),
the parties  hereto shall cause the Merger to be  consummated by filing with the
Secretary of State of Delaware in accordance  with Section 251 or Section 253 of
the Delaware Law three duplicate original certificates of merger with respect to
the  Merger  (the  "Certificates  of  Merger"),  in the  form and  executed  and
acknowledged  as required by Section 103 of the  Delaware  Law. The Merger shall
become  effective  at the time of such filing or at such other  subsequent  time
specified in the  Certificate  of Merger.  The time and date on which the Merger
shall become effective is referred to as the "Effective Time."

     1.4 Certificate of Incorporation and Bylaws.

     (a) The Certificate of Incorporation of MergerSub, as in effect immediately
prior to the Effective Time,  shall be the Certificate of  Incorporation  of the
Surviving  Corporation as amended by the  Certificate of Merger,  and thereafter
shall continue to be its Certificate of Incorporation  until amended as provided
therein  and under  the  Delaware  Law,  except  that the name of the  Surviving
Corporation shall be "Barefoot Inc."

     (b)  The  Bylaws  of  MergerSub,  as in  effect  immediately  prior  to the
Effective Time, shall be the Bylaws of the Surviving  Corporation and thereafter
shall continue to be its Bylaws until amended as provided  therein and under the
Delaware Law.

     1.5 Directors and Officers.  Unless  otherwise  determined by ServiceMaster
prior to the Effective Time, the officers of Barefoot holding office immediately
prior to the Effective Time shall be the officers (holding the same positions as
they held with  Barefoot) of the  Surviving  Corporation  immediately  after the
Effective  Time,  to hold office  until their  successors  have been elected and
shall  qualify  or  as  otherwise  provided  by  the  Bylaws  of  the  Surviving
Corporation. Unless otherwise determined by ServiceMaster prior to the Effective
Time,  the  directors  of  MergerSub  holding  office  immediately  prior to the
Effective Time shall be the directors of the Surviving  Corporation  immediately
after the  Effective  Time,  to hold  office  until their  successors  have been

                                      -59-



elected  and  shall  qualify  or as  otherwise  provided  by the  Bylaws  of the
Surviving Corporation.

                                   ARTICLE II
                              Conversion of Shares

     2.1  Conversion  of MergerSub  Common  Stock.  Each of the shares of common
stock of MergerSub ("MergerSub Common Stock") issued and outstanding immediately
prior to the  Effective  Time  shall,  by virtue of the Merger and  without  any
action on the part of the holder  thereof,  be converted  into and represent the
right to receive one fully paid and non-assessable  share of common stock of the
Surviving Corporation ("Surviving Corporation Common Stock"). From and after the
Effective Time, each outstanding certificate theretofore  representing shares of
MergerSub Common Stock shall be deemed for all purposes to evidence ownership of
and to represent the number of shares of Surviving Corporation Common Stock into
which such shares of MergerSub Common Stock shall have been converted.  Promptly
after  the  Effective  Time,  the  Surviving  Corporation  shall  issue  a stock
certificate or certificates  representing shares of Surviving Corporation Common
Stock in exchange for the certificate or certificates which formerly represented
the shares of MergerSub Common Stock, which shall be canceled.

     2.2 Conversion of Barefoot  Securities.  Each Share issued and  outstanding
immediately  prior to the  Effective  Time  shall,  by virtue of the  Merger and
without  any action on the part of the holder  thereof,  be  converted  into the
right to receive an amount, in cash, without interest, equal to the Merger Price
except that each of the following  Shares shall not be so  converted:  (i) every
Barefoot  Share held by  ServiceMaster  shall be canceled  and shall cease to be
outstanding;  (ii)  Dissenting  Shares (as defined in Section 2.4) in respect of
which  appraisal  rights are perfected  (which shall be treated as prescribed in
Section  2.4);  and (iii) every Share held in the treasury of Barefoot or by any
direct or indirect  subsidiary of Barefoot  (which shall be canceled and retired
at the Effective Time).

     2.3 Surrender of Certificates.

     (a) As soon as practicable  after the Effective Time, a person appointed by
ServiceMaster  to act as exchange  agent to effect the exchange of  certificates
(the  "Exchange  Agent") shall mail to each holder of record of a certificate or
certificates (the  "Certificates")  that immediately prior to the Effective Time
represented outstanding Shares (other than Shares excluded from conversion under
clauses (i) - (iii) in Section 2.2) a form letter of  transmittal  for return to
the Exchange Agent (which form shall specify that delivery of Certificates shall
be effected,  and risk of loss and title to the  Certificates  shall pass,  only
upon delivery of the  Certificates to the Exchange Agent) and  instructions  for
use in effecting  the surrender of the  certificates  in exchange for the Merger
Price. From time to time at or following the Effective time, ServiceMaster shall
deposit  with the  Exchange  Agent  in  trust  for the  benefit  of the  holders
immediately  available  funds  in an  amount  necessary  to  make  the  payments
contemplated  by  Section  2.2  hereof  on a timely  basis  (such  amount  being
hereinafter  referred to as the "Payment Fund"). Upon surrender of a Certificate
for  cancellation  to the Exchange Agent or to such other agent or agents as may

                                      -60-



be  appointed  by  ServiceMaster  and  Barefoot,  together  with such  letter of
transmittal and such documentation as shall be necessary effectively to transmit
the Certificate for cancellation, duly executed, the holder of such Certificates
shall be entitled  to receive in exchange  therefor  the Merger  Price,  and the
Certificate  so  surrendered  shall  forthwith be canceled.  The Exchange  Agent
shall,  pursuant to irrevocable  instructions,  make the payments referred to in
the preceding  sentence out of the Payment  Fund.  The Payment Fund shall not be
used for any other purpose except as described  herein.  Until  surrendered  and
exchanged, each such certificate shall represent solely the right to receive the
Merger Price for each Share  previously  represented  by that  certificate,  and
ServiceMaster  shall not be  required to pay the holder  thereof  any  property,
stock or cash to which such  holder  otherwise  would be entitled as a holder of
Barefoot  Common Stock,  provided  that  customary  and  appropriate  procedures
allowing for the surrender and exchange of former Shares  represented by lost or
destroyed certificates shall be provided.

     (b) Any cash in respect of the Merger Price  delivered or made available to
the  Exchange  Agent  pursuant  to  this  Section  2.3  and  not  exchanged  for
Certificates  within one year after the Effective  Time pursuant to this Section
2.3 shall be returned by the Exchange Agent to  ServiceMaster,  after which time
persons  entitled  thereto may look only to  ServiceMaster  for payment thereof,
subject  to the  rights of  holders  of  unsurrendered  Certificates  under this
Article II and subject to any applicable abandoned property,  escheat or similar
law.

     (c) If the  Merger  Price is to be issued to a person  whose  name is other
than  that  in  which  the  Certificate  surrendered  in  exchange  therefor  is
registered, it shall be a condition of the issuance thereof that the Certificate
so  surrendered  shall be properly  endorsed  and  otherwise  in proper form for
transfer, and that the person requesting such exchange shall pay to the Exchange
Agent any  transfer  or other  taxes  required  by reason of the  payment of the
Merger Price to a person whose name is other than that of the registered  holder
of the  Certificate so surrendered,  or required for any other reason,  or shall
establish to the  satisfaction of the Exchange Agent that such tax has been paid
or is not payable. Notwithstanding the foregoing, neither the Exchange Agent nor
any party hereto shall be liable to a holder of any  Certificate  for any amount
paid to or deposited with a public official pursuant to any applicable abandoned
property, escheat or similar law.

     (d) After the  Effective  Time,  there shall be no  transfers  on the stock
transfer books for the Surviving Corporation of the Shares that were outstanding
immediately  prior  to  the  Effective  Time.  If,  after  the  Effective  Time,
Certificates representing such shares are presented for transfer to the Exchange
Agent or to the Surviving Corporation,  they shall be canceled and exchanged for
the Merger Price.

     2.4 Dissenting  Shares.  Notwithstanding  anything in this Agreement to the
contrary,  but  only in the  circumstances  and to the  extent  provided  by the
Delaware Law,  Shares that are issued and outstanding  immediately  prior to the
Effective Time and that are held by stockholders  who have not voted such Shares
in favor of the  approval and  adoption of the Merger  Agreement  and shall have
delivered a written demand for appraisal of such Shares in the manner (including
the  time  of  delivery)  provided  in  Section  262 of the  Delaware  Law  (the
"Dissenting  Shares")  shall not be converted  into or be  exchangeable  for the
right to receive  the  Merger  Price,  but shall be  entitled  to  receive  such
consideration  as shall be  determined  pursuant to Section 262 of the  Delaware

                                      -61-



Law;  provided,  however,  that,  if such holder shall have failed to perfect or
shall have  effectively  withdrawn or lost such holder's  right to appraisal and
payment under the Delaware Law, such holder's  Shares shall  thereupon be deemed
to have been  converted  into and to have  become  exchangeable  for,  as of the
Effective  Time,  the right to receive the Merger  Price,  without any  interest
thereon,  in  accordance  with  Section  2.2, and such Shares shall no longer be
Dissenting Shares.


                                   ARTICLE III
                            Amendment and Termination

     3.1 Amendment. This Agreement may not be amended except by an instrument in
writing signed on behalf of each of the parties hereto. The respective boards of
directors  of each of the  parties  hereto  shall  have the right to amend  this
Agreement  without  approval  of their  respective  stockholders  to the  extent
permitted by Section 251(d) of the Delaware Law.

     3.2 Termination. At any time prior to the Effective Time, whether before or
after  approval  by the  stockholders  of  the  Constituent  Corporations,  this
Agreement  may  (subject to the  provisions  in Section  6.1 of the  Acquisition
Agreement) be  terminated  and the Merger  abandoned by mutual  agreement of the
boards of directors  of Barefoot  and  ServiceMaster.  This  Agreement  shall be
automatically  terminated  if the  Acquisition  Agreement is validly  terminated
pursuant to the provisions of Section 6.1 thereof. The filing of the Certificate
of Merger with the Secretary of State of Delaware pursuant to Section 1.3 hereof
shall  constitute  certification  that this Agreement has not  theretofore  been
terminated.  If terminated as provided in this Section 3.2, this Agreement shall
forthwith become wholly void and of no further force and effect.


                                   ARTICLE IV
                                  Miscellaneous

     4.1   Counterparts.   This  Agreement  may  be  executed  in  one  or  more
counterparts, each of which together shall constitute one agreement.

     4.2  Governing  Law.  This  Agreement  shall be governed  in all  respects,
including  validity,  interpretation  and  effect,  by the laws of the  State of
Delaware.



                                     * * * *

     IN WITNESS WHEREOF, ServiceMaster,  MergerSub and Barefoot have caused this
Agreement  to be  executed  on the  date  first  written  above  by  their  duly
authorized officers.
