The address of ServiceMaster's principal executive offices is One ServiceMaster

     During the last five years, neither ServiceMaster, nor to the knowledge of

ITEM 3.   SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION

     Certain stockholders of LandCare have executed voting agreements pursuant
to which such stockholders committed to among other things vote in favor of the
merger involving ServiceMaster described under Item 4 below. ServiceMaster
conditioned its entering into the Merger Agreement (as defined under Item 4) on
such stockholders of LandCare committing to vote for the Merger, as evidenced by
such voting agreements. ServiceMaster did not pay any funds to such stockholders
of

                              Page 3 of 10 Pages
<PAGE>
 
LandCare in connection with their entering into such voting agreements. If the
Merger is consummated, each share of LandCare common stock will be converted
into the right to receive a fraction of one share of ServiceMaster common stock
as provided in the Merger Agreement.


ITEM 4.   PURPOSE OF TRANSACTION

Merger Agreement

     LandCare, ServiceMaster and a wholly-owned subsidiary of ServiceMaster
("Merger Subsidiary") entered into a Plan of Reorganization and Agreement and
Plan of Merger dated as of November 1, 1998 (the "Merger Agreement") pursuant to
which Merger Subsidiary will be merged with and into LandCare, whereupon the
separate corporate existence of Merger Subsidiary will cease, and LandCare will
continue as the surviving corporation and will become a subsidiary of
ServiceMaster (the "Merger"). The Merger Agreement is subject to certain closing
conditions and termination events. In connection with the Merger, each issued
and outstanding share of LandCare common stock will be converted into a fraction
of one share of ServiceMaster common stock as established pursuant to the terms
of the Merger Agreement.

     In connection with the Merger, ServiceMaster intends to replace the
present board of directors of LandCare and to amend and restate the certificate
of incorporation and bylaws of LandCare as indicated in the Merger Agreement.
The Merger, which is subject to regulatory and LandCare stockholder approval,
and other closing conditions, is expected to close during the first quarter of
1999.

     Upon consummation of the Merger, LandCare common stock will be delisted
from the New York Stock Exchange and deregistered under the Securities Exchange
Act of 1934, as amended.

Sections 13D or 16 of the Securities Exchange Act of 1934, as amended, or for
any other purpose and such beneficial ownership is expressly disclaimed.

LandCare Common Stock other than the LandCare Common Stock that may be deemed to

          This Plan of Reorganization and Agreement and Plan of Merger (this
"Agreement") has been made as of November 1, 1998 (the "date hereof") among
 ---------                                              -----------  
LandCare USA, Inc., a Delaware corporation ("LandCare"), The ServiceMaster
                                             --------
Company, a Delaware corporation ("ServiceMaster"), and SVM Acquisition
                                  -------------

                -----------------     
          WHEREAS, the respective boards of directors of ServiceMaster, Merger

interests of their respective stockholders, this Agreement and the acquisition
of LandCare by ServiceMaster on the terms and conditions set forth herein.

          WHEREAS, ServiceMaster has entered into Voting Agreements with
stockholders of LandCare who collectively own approximately 30% of LandCare's
Common Stock outstanding on the date hereof (the "Voting Agreements").

          The parties hereto agree as follows:


                                   ARTICLE 1

                                  THE MERGER

          Section 1.1  The Merger.
                       ----------

                  (a)  Upon the terms and subject to the conditions set forth in
this Agreement, at the Effective Time (as hereinafter defined), Merger

                                 ------
with the General Corporation Law of the State of Delaware ("Delaware Law"),
                                                            ------------    
whereupon the separate existence of Merger Subsidiary shall cease, and LandCare

                                                  ---------------------


                  (b)  As soon as practicable after satisfaction or, to the

herein, LandCare and Merger Subsidiary will file a certificate of merger with
the Secretary of State of the State of Delaware and make all other filings or
recordings required by Delaware Law in connection with the Merger. The Merger
shall become effective at such time as the certificate of merger is duly filed
with the Secretary of State of the State of Delaware or at such later time as is
agreed by ServiceMaster and LandCare and specified in the certificate of merger
(the "Effective Time").

             Consideration."

     Section 1.3  Surrender and Payment.
                  ---------------------

                  (a) Prior to the Effective Time, ServiceMaster shall appoint
an agent reasonably acceptable to LandCare (the "Exchange Agent") for the
                                                 -------------- 
purpose of exchanging certificates representing Shares for the Merger
Consideration. Immediately following the Effective Time, ServiceMaster shall
deposit with the Exchange Agent, for the benefit of the holders of certificates
formerly representing Shares, the Merger Consideration issuable pursuant to
Section 1.2(a)(iii) in exchange for outstanding Shares. Promptly after the
Effective Time, ServiceMaster will send, or will cause the Exchange Agent to
send, to each holder of Shares at the Effective Time (i) a letter of transmittal
for use in such exchange (which shall specify that delivery of the Merger
Consideration shall be effected, and risk of loss and title to the certificates
representing ServiceMaster Common Stock and LandCare Common Stock shall pass,
only upon proper deliver of the certificates formerly representing Shares to the
Exchange Agent) and (ii) instructions for use in effecting the surrender of the
certificates formerly representing Shares in exchange for the Merger
Consideration.

                  (b) Each holder of Shares that have been converted into a
right to receive the Merger Consideration, upon surrender to the Exchange Agent
of a certificate or certificates formerly representing such Shares, together
with a properly completed and duly executed letter of transmittal covering such
Shares and such other documents as may reasonably be required by the Exchange
Agent, will be entitled to receive the Merger Consideration payable in respect
of such Shares and any dividends payable pursuant to Section 1.3(f). Until so
surrendered, each such certificate shall, after the Effective Time, represent
for all purposes only the right to receive the Merger Consideration and any
dividends payable pursuant to Section 1.3(f), without interest.

                  (c) If any portion of the Merger Consideration is to be paid
to a Person other than the registered holder of the Shares formerly represented
by the certificate or certificates surrendered in exchange therefor, it shall be
a condition to such payment that the certificate or certificates so surrendered
shall be properly endorsed or otherwise be in proper form for transfer and that
the Person requesting such payment shall pay to the Exchange Agent any transfer
or other taxes required as a result of such payment to a Person other than the
registered holder of

                                      -4-
<PAGE>
 
such Shares represented by the certificate or certificates so surrendered or
establish to the satisfaction of the Exchange Agent that such tax has been paid
or is not applicable.

          (d)  After the Effective Time, there shall be no further registration
of transfers of Shares. If, after the Effective Time, certificates formerly
representing Shares are presented to the Surviving Corporation, they shall be
canceled and exchanged for the consideration provided for, and in accordance
with the procedures set forth, in this Article 1.

          (e)  Any portion of the Merger Consideration made available to
the Exchange Agent pursuant to Section 1.3(a) that remains unclaimed by the
holders of Shares one year after the Effective Time shall be returned to
ServiceMaster, upon demand, and any such holder who has not exchanged his Shares
for the Merger Consideration in accordance with this Section 1.3 prior to that
time shall thereafter look only to ServiceMaster for payment of the Merger
Consideration and any dividends payable pursuant to Section 1.3(f) in respect of
his Shares. Neither ServiceMaster, LandCare nor the Exchange Agent shall be
liable to any person in respect of any shares of ServiceMaster Common Stock, any
dividends or distributions with respect thereto or any cash in lieu of
fractional shares of ServiceMaster Common Stock, in each case, delivered to a
public official pursuant to any applicable abandoned property, escheat or
similar law. If any certificate representing Shares shall not have been
surrendered prior to two years after the Effective Time (or immediately prior to
such earlier date on which any Merger Consideration, any dividends or
distributions payable to the holder of such certificate or any cash payable to
the holder of such certificate formerly representing LandCare Common Stock
pursuant to this Article 1, would otherwise escheat to or become the property of
any Governmental Entity (as hereinafter defined)), any such Merger
Consideration, dividends or distributions in respect of such certificate or such
cash shall, to the extent permitted by applicable law, become the property of
the Surviving Corporation, free and clear of all claims or interest of any
person previously entitled thereto.

               (f)  No dividends or other distributions with respect to
ServiceMaster Common Stock issued in connection with the Merger shall be paid to
the holder of any unsurrendered certificates formerly representing Shares until
such certificates are surrendered as provided in this Section 1.3. Subject to
the effect of applicable laws, following the surrender of such certificates,
there shall be paid, without interest, to the record holder of ServiceMaster
Common Stock issued in exchange therefor at the time of such surrender, the
amount of dividends or other distributions with a record date after the
Effective Time payable prior to or on the date of such surrender with respect to
such whole shares of ServiceMaster Common Stock and not previously paid, less
the amount of any withholding taxes which may be required thereon.

               (g)  The Exchange Agent shall invest any cash deposited with
the Exchange Agent, as directed by ServiceMaster, on a daily basis. Any interest
and other income resulting from such investments shall be paid to ServiceMaster.

               (h)  If any certificate representing Shares shall have been
lost, stolen or destroyed, upon the making of an affidavit of that fact by the
person claiming such certificate to be lost, stolen or destroyed and, if
required by the Surviving Corporation, the posting by such person of a bond in
such reasonable amount as the Surviving Corporation may direct as indemnity
against any claim that may be made against it with respect to such certificate,
the Exchange Agent shall issue in exchange for such lost, stolen or destroyed
certificate the Merger Consideration and, if applicable, any unpaid dividends
and distributions on shares of ServiceMaster Common Stock deliverable in respect
thereof and any cash in lieu of fractional shares, in each case, due to such
person pursuant to this Agreement.

     Section 1.4    Stock Options.
                    -------------

          (a)  As soon as practicable following the date of this Agreement, the
Board of Directors of LandCare (and, if appropriate, any committee administering
its 1998 Long-Term Incentive Plan and 1998 Non-Employee Director's Stock Plan
(the "LandCare Option Plans")) shall adopt such resolutions or take such other
      ---------------------
actions as may be required to effect the following:

               (i)  adjust the terms of all outstanding LandCare Stock Options
          (defined below) granted under the LandCare Option Plans and the terms
          of the LandCare Option Plans, to provide that at the Effective Time,
          each LandCare Stock Option outstanding immediately prior to the
          Effective Time shall be deemed to constitute an option to acquire, on
          the same terms and conditions as were applicable under such LandCare
          Stock Option (subject to adjustments and lapsing of restrictions,
          vesting or acceleration of exercisability of LandCare Stock Options
          required by this Section 1.4), the same number of shares of
          ServiceMaster Common Stock as the holder of such LandCare Stock Option
          would have been entitled to receive pursuant to the Merger had such
          holder exercised such LandCare Stock Option in full immediately prior
          to the Effective Time, at a price per share equal to the quotient
          derived by dividing the Exchange Ratio into the exercise price per
          share at which the LandCare Common Stock shall have been purchasable
          on exercise of such LandCare Stock Option prior to the Effective Time;
          and

               (ii) make such other changes to the LandCare Option Plans as it
          deems appropriate to give effect to the Merger (subject to approval of
          ServiceMaster, which shall not be unreasonably withheld).

          (b)  At the Effective Time and subject to the last sentence to
this Section 1.4(b), all conditions and restrictions relating to all outstanding
LandCare Stock Options which have been granted pursuant to the LandCare Option
Plans (the "LandCare Stock Options"), including limitations on exercisability,
           ------------------------
risks of forfeiture and conditions and restrictions requiring continued
performance of services with respect to the exercisability or settlement of such
LandCare Stock Options, shall immediately lapse. LandCare shall use diligent
efforts to cause the individuals listed

                                      -6-
<PAGE>
 
in Section 1.4(b) of the LandCare Disclosure Schedule (as hereinafter defined)
(hereinafter referred to as the "Senior Option Holders") to waive the complete
                                 ---------------------  
lapsing of conditions and restrictions relating to exercisability of LandCare
Stock Options set forth above, and accept a modified vesting schedule whereby
one-half of each Senior Option Holder's LandCare Stock Options shall vest and
thereafter be exercisable as provided in the respective LandCare Option
Agreement on the date six months immediately following the Effective Time, and
the remaining one-half of such LandCare Stock Options shall vest and thereafter
be exercisable as provided in the respective LandCare Option Agreement on the
first anniversary of the Effective Time; provided, however, in the event a
Senior Option Holder's employment is terminated by LandCare without Cause (as
defined in the respective Senior Option Holder's employment agreement with
LandCare) or if the Senior Option Holder elects to terminate his employment with
LandCare for Good Reason (as defined in the respective Senior Option Holder's
employment agreement with LandCare) the unvested portion of such Senior Option
Holder's LandCare Stock Options shall immediately vest and be exercisable for a
period of three months following termination of employment.

          (c)   As soon as practicable after the Effective Time, ServiceMaster
shall deliver to the holders of LandCare Stock Options appropriate notices
setting forth such holders' rights pursuant to the respective LandCare Option
Plans and the agreements evidencing the grants of such LandCare Stock Options
shall continue in effect on the same terms and conditions (except as expressly
provided above).

          (d)   ServiceMaster shall take all corporate action necessary to
reserve for issuance a sufficient number of shares of ServiceMaster Common Stock
for delivery on exercise of the LandCare Stock Options assumed in accordance
with this Section 1.4. As soon as reasonably practicable after the Effective
Time, ServiceMaster shall file a registration statement on Form S-8 (or any
successor or other appropriate form) with respect to the shares of ServiceMaster
Common Stock subject to such LandCare Stock Options and shall use reasonable
efforts to maintain the effectiveness of such registration statement or
registration statements (and maintain the current status of the prospectus or
prospectuses contained therein) for so long as such LandCare Stock Options
remain outstanding.

   Section 1.5  Fractional Shares.
                ----------------- 

          (a)   No certificates or scrip representing fractional shares of
ServiceMaster Common Stock shall be issued upon the surrender for exchange of
certificates formerly representing Shares, no dividend or distribution of
ServiceMaster shall relate to such fractional share interests and such
fractional share interests will not entitle the owner thereof to vote or to any
rights of a stockholder of ServiceMaster.

          (b)   As promptly as practicable following the Effective Time,
ServiceMaster shall cause the Exchange Agent to determine the excess of (i) the
number of whole shares of ServiceMaster Common Stock delivered to the Exchange
Agent by ServiceMaster pursuant to

                                      -7-
<PAGE>
 
Section 1.3(a) hereof over (ii) the aggregate number of whole shares of
ServiceMaster Common Stock to be distributed to former holders of Shares
pursuant to Section 1.3(b) hereof (such excess being herein called the "Excess 
                                                                        ------  
Shares"). Following the Effective Time, the Exchange Agent shall, on behalf of
- ------ 
former holders of certificates representing Shares, sell the Excess Shares at
then-prevailing prices on the NYSE, all in the manner provided in this Section.

          (c)  The sale of the Excess Shares by the Exchange Agent shall
be executed on the NYSE through one or more member firms of the NYSE and shall
be executed in round lots to the extent practicable. ServiceMaster shall cause
the Exchange Agent to use reasonable efforts to complete the sale of the Excess
Shares as promptly following the Effective Time as, in the Exchange Agent's sole
judgment, is practicable consistent with obtaining the best execution of such
sales in light of prevailing market conditions. Until the net proceeds of such
sale or sales have been distributed to the holders of certificates formerly
representing Shares, the Exchange Agent shall hold such proceeds in trust for
such holders (the "Common Stock Trust"). The Surviving Corporation shall pay all
                  --------------------
commissions, transfer taxes and other out-of-pocket transaction costs, including
the expenses and compensation of the Exchange Agent incurred in connection with
such sale of the Excess Shares. The Exchange Agent shall determine the portion
of the Common Stock Trust to which each former holder of Shares is entitled, if
any, by multiplying the amount of the aggregate net proceeds comprising the
Common Stock Trust by a fraction, the numerator of which is the amount of the
fractional share interest to which such former holder of Shares is entitled
(after taking into account all Shares held at the Effective Time by such holder)
and the denominator of which is the aggregate amount of fractional share
interests to which all former holders of Shares are entitled.

          (d)  Notwithstanding subsections (a), (b) and (c) above, the
Surviving Corporation may elect at its option, exercised prior to the Effective
Time, in lieu of the issuance and sale of Excess Shares and the making of the
payments herein above contemplated, to pay each former holder of Shares an
amount in cash equal to the product obtained by multiplying (i) the fractional
share interest to which such former holder (after taking into account all Shares
held at the Effective Time by such holder) would otherwise be entitled by (ii)
the closing price for a share of ServiceMaster Common Stock as reported on the
NYSE Composite Transaction Tape (as reported in The Wall Street Journal, or, if
not reported thereby, any other authoritative source) on the Closing Date (as
hereinafter defined), and, in such case, all references herein to the cash
proceeds of the sale of the Excess Shares and similar references shall be deemed
to mean and refer to the payments calculated as set forth in this subsection
(d).

          (e)  As soon as practicable after the determination of the
amount of cash, if any, to be paid to holders of certificates formerly
representing Shares with respect to any fractional share interests,
ServiceMaster shall cause the Exchange Agent to make available such amounts to
such holders of certificates formerly representing Shares, subject to surrender
of such certificates in accordance with Section 1.3. For purposes of this
Section 1.5, Shares of any holder represented

                                      -8-
<PAGE>
 
by two or more certificates may be aggregated, and in no event shall any holder
be paid an amount in cash in respect of more than one share of ServiceMaster
Common Stock.

     Section 1.6  Adjustments. In the event of any stock dividend in respect
                  -----------  
of outstanding ServiceMaster Common Stock, or of any split, combination or
reclassification of the outstanding ServiceMaster Common Stock or of any
issuance of any other securities in exchange or in substitution for outstanding
shares of ServiceMaster Common Stock at any time during the period from the date
of this Agreement to the Effective Time, LandCare and ServiceMaster shall make
such adjustment to the Merger Consideration as LandCare and ServiceMaster shall
mutually agree so as to preserve the economic benefits that LandCare and
ServiceMaster each reasonably expected on the date of this Agreement to receive
as a result of the consummation of the Merger and the other transactions
contemplated by this Agreement.

     Section 3.1 Organization. Each of LandCare and its Subsidiaries is a
                 ------------   
corporation duly organized, validly existing and in good standing under the laws
of the jurisdiction of its incorporation, and has all requisite corporate power
and authority and all necessary governmental approvals to own, lease and operate
its properties and to carry on its business as now being conducted, except where
the failure to be so organized, existing and in good standing or to have such
power, authority and governmental approvals would not have a material adverse
effect on LandCare and its Subsidiaries taken as a whole. Each of LandCare and
its Subsidiaries is duly qualified or licensed to do business and in good
standing in each jurisdiction in which the property owned, leased or operated by
it or the nature of the business conducted by it makes such qualification or
licensing necessary, except where the failure to be so duly qualified or

adverse effect on LandCare and its Subsidiaries taken as a whole.

     Section 3.2 Corporate Authorization; Validity of Agreement; Board Action.
                 ------------------------------------------------------------

and deliver this Agreement and, subject to obtaining any necessary approval of
its stockholders as contemplated by Section 5.2 with respect to the adoption of
this Agreement, to consummate the transactions contemplated hereby. The
execution, delivery and performance by LandCare of this Agreement, and the
consummation by it of the transactions contemplated hereby, have been duly and
validly authorized by its board of directors and, except for obtaining the

respect to the adoption of this Agreement, no other corporate action or
proceedings on the part of LandCare is necessary to authorize the execution and
delivery by LandCare of this Agreement, and the consummation by it of the
transactions contemplated hereby. This Agreement has been duly executed and
delivered by LandCare and, assuming this Agreement constitutes a valid and
binding obligation of ServiceMaster and Merger Subsidiary, constitutes a valid
and binding obligation of LandCare, enforceable against LandCare in accordance
with its terms, except that (i) such enforcement may be subject to applicable
bankruptcy, insolvency or other similar laws, now or hereafter in effect,
affecting creditors' rights generally, and (ii) the remedy of specific
performance and injunctive and other forms of equitable relief may be subject to
equitable defenses and to the discretion of the court before which any
proceeding therefor may be brought.

             (b) The affirmative vote of the holders of a majority of the
LandCare Common Stock outstanding at the record date for the LandCare
Stockholders Meeting is the only vote of the holders of any class or series of
capital stock of LandCare necessary to adopt this Agreement, and thus to approve
of the transactions contemplated by this Agreement.

          filed in connection with the determination, assessment or collection

          administrative requirements relating to any Tax.

          (b)  Tax Filings and Payments.

               (i)    All Returns (as hereinafter defined) required to be filed
          on or before the date hereof and the date of the Closing by or on
          behalf of LandCare have been duly filed on a timely basis and such
          Returns are true, correct and complete in all material respects,
          except that such returns may contain inadvertent errors and omissions
          which are not material.

               (ii)   LandCare has timely paid or made adequate provision for
          all Taxes and, no other material Taxes are payable by LandCare with
          respect to items or periods covered by such Returns (whether or not

               (iii)  LandCare has made or will make adequate provision for all
          Taxes payable for any periods that end on or before the Closing for
          which no Returns have yet been filed and for any periods that begin

          are attributable to the portion of any such period ending at the
          Closing.

               (iv)   The charges, accruals and reserves for current Taxes
          (excluding reserves for deferred Taxes) reflected on the books of
          LandCare are not materially less than the Tax liabilities accruing or
          payable by LandCare in respect of periods prior to the date hereof and
          such charges, accruals and reserves are reflected on LandCare's most
          recent financial statements.

               (v)    LandCare is not delinquent in the payment of any Taxes or
          has requested any extension of time within which to file or send any

          have not been paid.

               (vi)   No deficiencies exist for any Taxes or any penalties,
          interest or assessments nor have any been proposed, asserted, or
          assessed against LandCare that are not adequately reserved for.

               (vii)  There is no dispute or claim concerning any material Tax
          liability of LandCare either (A) claimed or raised by any authority in
          writing or (B) as to which LandCare has knowledge based upon personal
          contact with any agent of such authority.

               (viii) There is no pending audit, examination, or, to LandCare's
          knowledge, any investigation of any Return by any authority nor has
          LandCare received any notice of such audit, examination, or
          investigation.

               (ix)   LandCare has not waived any statute of limitations in
          respect of Taxes or granted any extension of the limitations period
          applicable to any claim of Taxes.

               (x)    LandCare is not subject to liability for Taxes of any
          person (other than LandCare or any other member of the affiliated
          group of corporations that files a consolidated federal income tax
          return, of which LandCare is the common parent), including, without
          limitation, liability arising from the application of U.S. Treasury
          Regulation section 1.1502-6 or any analogous provision of state, local
          or foreign law.

               (xi)   LandCare is not nor has it ever been a party to any tax
          sharing agreement with any entity.

               (xii)  To LandCare's knowledge, no claim has ever been made by an
          authority in a jurisdiction where LandCare does not file Returns that
          it is or may be subject to taxation by that jurisdiction.

               (xiii) There are no liens on any of the assets of LandCare that
          arose in connection with any failure (or alleged failure) to pay any
          Taxes.

               (xiv)  LandCare has withheld and paid over and complied with all
          material information reporting and backup withholding requirements,
          including, without limitation, maintenance of required records with

          employee, independent contractor, creditor, stockholder, or other
          third party.

               (xv)   LandCare does not expect any authority to assess any
          additional Taxes for any period for which Returns have been filed
          except to an extent consistent with LandCare's past experience as
          reflected in its publicly released financial statements.

               (xvi)  LandCare has delivered to ServiceMaster correct and
          complete copies of all Returns, examination reports, and statements of

               (xviii) All material net operating losses, credits and other tax
          attributes utilized by LandCare during any taxable year ending on or
          prior to the Closing were fully and properly available to LandCare
          under all applicable tax laws, regulations and administrative

               (i)    To LandCare's knowledge, no stockholder of LandCare who
          owns more than 5% of LandCare's Common Stock is a "foreign person" (as

               (ii)   LandCare is not a "consenting corporation" under Section

               (iii)  LandCare has not entered into any compensatory agreement
          with respect to the performance of services which payment thereunder
          would result in a nondeductible expense to LandCare pursuant to

          of such payment pursuant to Section 4999 of the Code.

               (iv)   LandCare has not agreed, nor is it required to make, any

          a result of any "closing agreement" described in Section 7121 of the
          Code (or any corresponding provision of state, local or foreign income
          Tax law), to include any item of income in, or exclude any item of
          deduction from, taxable income for any taxable period (or portion
          thereof) ending after the Closing.

               (vi)   LandCare will not be required as a result of any deferred
          intercompany gain described in Treasury Regulation Section 1.1502-13
          or any excess loss account described in Treasury Regulation Section
          1.1502-19 (or any corresponding or similar provision or administrative
          rule of federal, state, local or foreign income tax law), to include
          any item of income in taxable income for any period (or portion
          thereof) ending after the Closing Date.

     Section 3.15 Contracts. Each material LandCare Agreement is valid, binding
                  ---------
and enforceable and in full force and effect, except where failure to be valid,
binding and enforceable and in full force and effect would not have a material
adverse effect on LandCare and its Subsidiaries taken as a whole, and there are
no defaults thereunder, except those defaults that would not have a material
adverse effect on LandCare and its Subsidiaries taken as a whole. Neither
LandCare nor any of its Subsidiaries is a party to any agreement that expressly
and materially limits the ability of LandCare or any of its Subsidiaries to
compete in or conduct any line of business or compete with any person or in any
geographic area or during any period of time. All material contracts of LandCare
and its Subsidiaries will continue to be legal, valid, binding and enforceable,

          (e)  None of LandCare or its Subsidiaries, or their respective
predecessors, has treated, stored, disposed of, arranged for or permitted the
disposal of, transported, handled or released any substance, including without

          (g)  Neither LandCare nor its Subsidiaries has, either expressly or by

                                      -24-

facilities, properties or operations of LandCare, its Subsidiaries or any of
their predecessors will prevent, hinder or limit continued compliance with

                                 WARRANTIES OF
                      SERVICEMASTER AND MERGER SUBSIDIARY

         References in this Agreement to the "ServiceMaster Disclosure Schedule"

mean the document captioned "ServiceMaster Disclosure Schedule" as constituted
upon its delivery to LandCare prior to LandCare's execution and delivery of this
Agreement. ServiceMaster warrants to LandCare, subject in the case of the
warranties in each particular section below to the exceptions set forth in the
corresponding section of the ServiceMaster Disclosure Schedule:

         Section 4.1 Organization. ServiceMaster is a corporation duly
                     ------------
organized, validly existing and in good standing under the laws of the State of
Delaware. Merger Subsidiary is a corporation duly organized, validly existing
and in good standing under the laws of the State of Delaware. Each of
ServiceMaster and its Subsidiaries has all requisite corporate or other power
and authority and all necessary governmental approvals to own, lease and operate
its properties and to carry on its business as now being conducted, except where
the failure to be so organized, existing and in good standing or to have such
power, authority and governmental approvals would not have a material adverse
effect on ServiceMaster and its subsidiaries taken as a whole. ServiceMaster and
each of its Subsidiaries is duly qualified or licensed to do business and in
good standing in each jurisdiction in which the property owned, leased or
operated by it or the nature of the business conducted by it makes such
qualification or licensing necessary, except where the failure to be so duly
qualified or licensed and in good standing would not in the aggregate, have a
material adverse effect on ServiceMaster and its Subsidiaries taken as a whole.
Merger Subsidiary has not heretofore conducted any business other than in
connection with this Agreement and the transactions contemplated hereby.

         Section 4.2 Corporate Authorization; Validity of Agreement; Necessary
                     ---------------------------------------------------------
Action. ServiceMaster and Merger Subsidiary have full corporate power and
- ------
authority to execute and deliver this Agreement and to consummate the
transactions contemplated hereby. The execution, delivery and performance by
ServiceMaster and Merger Subsidiary of this Agreement and the consummation by
ServiceMaster and Merger Subsidiary of the transactions contemplated hereby have
been duly and validly authorized by their respective boards of directors and no
other corporate action or proceedings on the part of ServiceMaster and Merger
Subsidiary are necessary to authorize the execution and delivery by
ServiceMaster and Merger Subsidiary of this Agreement, and the consummation by
ServiceMaster and Merger Subsidiary of the transactions contemplated hereby.
This Agreement has been duly executed and delivered by ServiceMaster and Merger
Subsidiary, and, assuming this Agreement constitutes a valid and binding
obligation of LandCare, constitutes a valid and binding obligation of each of
ServiceMaster and Merger Subsidiary, enforceable against each of them in
accordance with their terms, except that (i) such enforcement may be subject to
applicable bankruptcy, insolvency or other similar laws, now or hereafter in
effect, affecting creditors' rights generally, and (ii) the remedy of specific
performance

                                      -27-

defenses and to the discretion of the court before which any proceeding therefor
may be brought. ServiceMaster Common Stock to be issued in connection with the
Merger will when issued be duly authorized, validly issued, fully paid and
nonassessable and not subject to preemptive rights. No vote of the holders of
ServiceMaster Common Stock is necessary for ServiceMaster to consummate the
Merger or to issue the shares of ServiceMaster Common Stock to be issued in
connection with the Merger or for Merger Subsidiary to consummate the Merger.

Merger Subsidiary nor the consummation by ServiceMaster and Merger Subsidiary of
the transactions contemplated hereby nor compliance by ServiceMaster and Merger

convene the LandCare Stockholders Meeting and shall submit for (or shall not

                      ---------------

                (a)   LandCare warrants to ServiceMaster that the board of
directors of LandCare has (i) made such assessments of LandCare's value and has
taken such other actions as to satisfy the fiduciary duties of its board of
directors that must be satisfied to enable LandCare to enter into this Agreement
and to render this Agreement binding upon LandCare in accordance with its terms
and (ii) has adopted a resolution approving this Agreement and declaring its
advisability.

                (b)   LandCare agrees that, prior to the Effective Time, it

its or its Subsidiaries' directors, officers, employees, agents or
representatives, directly or indirectly, to solicit, initiate or knowingly
encourage (including by way of furnishing or disclosing non-public information)
any inquiries or the making of any proposal with respect to any merger,
consolidation or other business combination involving LandCare or the
acquisition of all or any material portion of the assets or capital stock of
LandCare (an "Acquisition Transaction") or negotiate, explore or otherwise
              ----------------------- 
engage in substantive discussions with any person (other than ServiceMaster,
Merger Subsidiary or their respective directors, officers, employees, agents and
representatives), or enter into any agreement, with respect to any Acquisition
Transaction or enter into any agreement, arrangement or understanding requiring
it to abandon, terminate or fail to consummate the Merger or any other
transactions contemplated by this Agreement.

<PAGE>
 
                (c)   Notwithstanding subsection (b) above:

                      (i)  LandCare may provide non-public information to
                and seek to negotiate an Acquisition Transaction with a person
                (the "Competitor") provided that the Competitor shall make a
                      ----------
                bona fide unsolicited written proposal to make an Acquisition
                Transaction for all the capital stock or assets of LandCare on
                Superior Terms. For purposes of this Agreement, terms will be
                deemed to be "Superior Terms" only if the proposal of such
                              --------------
                Competitor is more favorable than the Merger to the stockholders
                of LandCare as determined in good faith by the board of
                directors of LandCare. A proposal to acquire LandCare on
                Superior Terms is herein called a "Qualified Competing
                                                   -------------------
                Proposal." LandCare shall prior to entering into an agreement
                --------
                with respect to a Qualified Competing Proposal pay or cause to
                be paid to ServiceMaster the amount specified in Section 9.4(b).
                Nothing contained in this Agreement shall prevent the board of
                directors of LandCare from complying with Rule 14c-2 under the
                Exchange Act with regard to an Acquisition Transaction.

                      (ii) If LandCare receives a Qualified Competing
                Proposal, LandCare will nevertheless (i) permit its stockholders
                to vote on the adoption of this Agreement and (ii) not take any
                action that would preclude LandCare from consummating the Merger
                if this Agreement is adopted by LandCare's stockholders or make
                the Merger any less advantageous to ServiceMaster if this
                Agreement is adopted by LandCare's stockholders. If this
                Agreement is adopted by LandCare's stockholders (i) LandCare
                will consummate the Merger and (ii) shall not consummate any
                Acquisition Transaction contemplated by a Qualified Competing
                Proposal.

                (d)   Upon executing this Agreement, LandCare shall immediately
advise ServiceMaster in writing regarding (i) the identity of any other persons
or entities with whom LandCare has had direct or indirect contact since January
1, 1998 regarding a possible Acquisition Transaction and (ii) the status of any
discussions or negotiations regarding a possible Acquisition Transaction
involving any such person or entity. LandCare warrants that LandCare is not
bound by any contract or agreement that would require it to take any action
which would violate any restriction contained in Section 5.4(b). Hereafter,
LandCare shall advise ServiceMaster in writing of the receipt, directly or
indirectly, of any inquiries or proposals relating to an Acquisition Transaction
promptly upon such receipt and of its intention to enter into any agreement
relating to an Acquisition Transaction which is a Qualified Competing Proposal
at least 48 hours prior to executing any such agreement, and promptly advise
ServiceMaster in writing of any actions taken pursuant to Section 5.4(c) hereof
and furnish to ServiceMaster either a copy of such proposal or a written summary
of such proposal.

         Section 5.5  Corporate Organization. Notwithstanding anything to the
                      ----------------------
contrary contained in this Agreement or in the disclosure schedules hereto,
LandCare and each of its Subsidiaries

                                      -35-
<PAGE>
 
shall take all actions necessary in order to be duly qualified and in good
standing on the Effective Time with the Secretary of State in each jurisdiction
in which the character of its properties owned or held under lease or the nature
of its activities makes such qualification necessary.

         Section 5.6  Pipeline Acquisitions.
                      ---------------------

                (a)   LandCare has delivered to ServiceMaster prior to the
execution of this Agreement a schedule captioned "Pipeline Schedule" which as
                                                  -----------------
constituted when so delivered to ServiceMaster prior to execution of this
Agreement is herein called the "Pipeline Schedule." LandCare warrants to
ServiceMaster that the Pipeline Schedule shows: (i) every enterprise with which
LandCare has entered into a letter of intent or binding acquisition agreement
contemplating the acquisition of such enterprise by LandCare which is in
existence on the date hereof (except that the acquisition of Albuquerque
Landscape identified in Section 5.6(f) shall not be deemed to be part of the
Pipeline Schedule); (ii) the purchase price for such enterprise specified in
such letter of intent or acquisition agreement; and (iii) the annual revenues
and proforma EBITDA that LandCare estimates such enterprise generated in the
trailing 12 months prior to the execution of the letter of intent with respect
to that enterprise.

                (b)   LandCare shall not enter into any letter of intent or
agreement to make any acquisition of any business enterprise or consummate any
acquisition of any business enterprise after the date hereof except that
LandCare may enter into purchase agreements for the enterprises shown on the
Pipeline Schedule on terms that comply with the requirements in Section 5.6(d)
and may consummate such acquisitions and except that LandCare shall have the
right to make additional acquisitions of enterprises not shown on the Pipeline
Schedule that comply with the requirements set forth in paragraphs (c) and (d)
of this Section 5.6.

                (c)   LandCare may without ServiceMaster's consent acquire
businesses not shown on the Pipeline Schedule provided that the standards in
Section 5.6(d) and the following additional standards are met with respect to
each such acquisition:

                      (i)  the purchase price payable for such business shall
                not exceed .8 times trailing twelve month revenues or six times
                trailing twelve month pro forma EBITDA for the business (both
                calculated in the same manner used to calculate trailing 12
                month revenues and pro forma EBITDA for purposes of the Pipeline
                Schedule and for purposes of this requirement all debt
                obligations to which the acquired enterprise shall be subject
                (net of excess cash) shall count as part of the purchase price);

                      (ii) such business shall have generated during the

                      (iii)  such business has a quality and potential
                comparable to the businesses shown on the Pipeline Schedule on
                the date hereof.

                (d)   The following requirements shall apply to every
acquisition made by LandCare after the date hereof ("New Acquisitions"):
                                                     ----------------

                      (i)   LandCare shall not use its LandCare Common Stock for
                any New Acquisition unless that such stock shall be valued for
                purposes of that acquisition at:

                            (A)  not less than the actual average closing price
                      for LandCare Common Stock during a five Trading Day period
                      ending within two Trading Days prior to the closing of the
                      New Acquisition;

                            (B)  not less than $9 per LandCare share; and

                            (C)  not less than $1 per LandCare share
                      issued in the New Acquisition below the "Applicable
                      ServiceMaster Deal Price." For purposes of this Section
                      5.6, the "Applicable ServiceMaster Deal Price" for
                                -----------------------------------
                      purposes of any particular New Acquisition shall be equal
                      to the Applicable Exchange Ratio times the average closing
                      price per share for ServiceMaster Common Stock for the
                      period of 20 consecutive Trading Days ending on the third
                      Trading Day before the date on which the particular New
                      Acquisition closes. The "Applicable Exchange Ratio" shall
                                               -------------------------
                      be the Exchange Ratio that would have been applicable if
                      the Scheduled Meeting Date coincided with the date on
                      which the New Acquisition shall close.

                      (ii)  LandCare shall limit the shares of LandCare Common
                Stock issuable in New Acquisitions so that in the aggregate the
                shares of LandCare Common Stock issued in such transactions will
                result in aggregate Deal Losses of not more than $1 million. For
                purposes of this requirement, the Deal Loss in any particular
                New Acquisition shall be the product derived by multiplying the
                number of shares of LandCare Common Stock issued in that New
                Acquisition times the amount by which the Applicable Service
                Master Deal Price shall exceed the value per share for which
                shares of LandCare Common Stock were valued for purposes of that
                New Acquisition.

                      (iii) LandCare shall not use LandCare Shares in any
                particular New Acquisition unless the characteristics of the
                persons receiving such stock and all other relevant
                considerations with respect to that New Acquisition are such
                that the use of such stock will not cause either LandCare or
                ServiceMaster to breach any of the requirements of the federal
                securities laws.

                      (iv)  The terms governing each New Acquisition will
                include (i) warranties to LandCare and indemnifications from the
                sellers comparable to the scope and value of the warranties
                usually obtained by LandCare in acquisitions made after its
                acquisition of its "founding companies" and prior to the date
                hereof and (ii) other terms as favorable to LandCare as the
                comparable terms in acquisitions made after its acquisition of
                its "founding companies" and prior to the date hereof. The
                indemnification and other rights that continue after the closing
                of a New Acquisition shall be on terms such that LandCare's
                rights will not be impaired or diminished in value by the
                consummation of the Merger. Without ServiceMaster's consent,
                such terms shall not allow the sellers to use stock to satisfy
                their indemnification obligations and shall prohibit the sellers
                from transferring any interest in the shares of LandCare Common
                Stock they receive in the deal (or in the ServiceMaster shares
                issued in the Merger to replace those Shares) for a period of
                one year after their New Acquisition closes.

                (e)   ServiceMaster shall have the right to terminate this
Agreement if by the Scheduled Meeting Date:

                (A)   LandCare shall not have completed and closed Qualified New
                Acquisitions that meet the following criteria: (i) the aggregate
                purchase price for the Qualified Pipeline Acquisitions shall not
                be more than 5% in excess of the aggregate of the projected
                acquisition prices projected on the Pipeline Schedule for New
                Acquisitions shown on that Schedule and closed prior to the
                Scheduled Meeting Date; and (ii) the aggregate purchase price
                for Qualified Post Pipeline Acquisitions shall not exceed the
                maximum price permitted by clause (i) in Section 5.6(c); and
                (iii) the trailing 12 month revenues for the Qualified New
                Acquisitions (measured as of the time each such New Acquisition
                closed) shall not be less than $46.6 million; and (iv) the
                trailing 12 month EBITDA for the Qualified New Acquisitions
                (measured as of the time each such New Acquisition closed) shall
                not be less than $5.9 million; or

                (B)   LandCare shall have made any New Acquisitions after the
                date hereof (other than Albuquerque Landscape) that are contrary
                to the requirements in paragraphs (c) or (d) in this Section
                5.6; or

                (C)   the aggregate trailing 12 month revenues of all businesses
                acquired in New Acquisitions closed prior to the Scheduled
                Meeting Date shall exceed $70 million.

                requirements paragraphs (c) and (d) of this Section 5.6 are
                herein called "Qualified Post Pipeline Acquisitions."
                               ------------------------------------

                      (iii) The term "Qualified New Acquisitions" means all
                                      --------------------------
                Qualified Pipeline Acquisitions and all Qualified Post Pipeline
                Acquisitions that shall have closed prior to the Scheduled
                Meeting Date.

                      (iv)  In the event ServiceMaster or any ServiceMaster
                subsidiary shall acquire any enterprise shown on the Pipeline
                Schedule, then for purposes of this Section 5.6(e) LandCare
                shall be deemed to have acquired such enterprise on the terms
                specified in the Pipeline Schedule for that enterprise.

                (f)   In the event LandCare shall within the next two weeks
close its acquisition of Albuquerque Landscape on the terms provided in the
definitive agreements governing that acquisition in effect on the date hereof,
then (i) such acquisition shall not be required to meet any of the standards
prescribed by this Section 5.6 but (ii) such acquisition shall not be deemed a
New Acquisition and shall not be taken into account in determining whether
ServiceMaster shall have a termination right under the provisions in Section
5.6(e).

                (g)   LandCare shall supply ServiceMaster at such time as

have been satisfied all information ServiceMaster shall reasonably request about
New Acquisitions.

diligent efforts to cause each of the convertible notes of LandCare described in
the section of LandCare Disclosure Schedule corresponding to Section 3.4(c) to
be redeemed and repaid in full for an amount less than the greater of (unless
otherwise agreed by ServiceMaster) (i) the outstanding principal amount of such
note plus accrued interest or (ii) the then market value of the LandCare shares
into which the notes would be convertible if the conversion were governed by the
conversion ratio applicable after a change in control.

Merger Subsidiary;

               (b)  by either LandCare or ServiceMaster, if the Merger has not
been consummated by May 1, 1999; provided that no party may terminate this
Agreement pursuant to this subsection if such party's failure to fulfill any of
its obligations under this Agreement shall have been the primary and but-for
reason that the Effective Time shall not have occurred on or before said date
and provided further that in no event shall ServiceMaster's failure to permit an
adjustment in the Exchange Ratio under Section 1.2(b)(iii) preclude or impair
ServiceMaster's right to terminate under this clause (b);

               (c)  by either LandCare or ServiceMaster, if there shall be any
judgment, injunction, order or decree enjoining ServiceMaster or LandCare from

               (d)  by either LandCare or ServiceMaster, if this Agreement shall
not have been adopted by the stockholders of LandCare at the LandCare

               (e)  by ServiceMaster or Merger Subsidiary, if the board of
directors of LandCare shall (i) withdraw, modify or change its recommendation or
approval in respect of this Agreement in a manner adverse to ServiceMaster or
(ii) have recommended any proposal other than by ServiceMaster or Merger
Subsidiary in respect of an Acquisition Transaction; and

               (f)  by ServiceMaster or Merger Subsidiary, if any corporation,

the Exchange Act) other than ServiceMaster or Merger Subsidiary or any of their
respective Subsidiaries or affiliates shall have become the beneficial owner of
more than 40% of the outstanding LandCare Common Stock (either on a primary or a
fully diluted basis).

               (g)  by ServiceMaster, if LandCare shall have breached

persons shall not have taken all actions necessary to cause the conversions
prescribed by Section 1.4(a) to occur automatically upon consummation of the
Merger; or

               (i)  by LandCare, if a Qualified Competing Proposal is made to
LandCare, subject to the restrictions set forth in Section 5.4(c)(ii); provided
that the right to terminate described in this subsection shall not be effective

subsection shall immediately expire and be of no force or effect if LandCare's
stockholders approve the Merger; or

               (j)  by LandCare, if ServiceMaster or Merger Subsidiary shall

subsequent to the date of this Agreement) in any material respect any of its
representations, warranties, covenants or agreements contained herein; or

               (k)  by LandCare if LandCare shall become entitled to terminate
under Section 1.2(b)(iii); or

               (l)  by ServiceMaster if the right to termination shall arise
under Section 5.6(e).

Such right of termination shall be exercised by written notice of termination
given by the terminating party to the other parties hereto in the manner
hereinafter provided. Any such right of termination shall not be an exclusive
remedy hereunder but shall be in addition to any other legal or equitable
remedies that may be available to any non-defaulting party hereto arising out of
any default hereunder by any other party hereto.

     Section 9.2    Waiver. At any time prior to the Effective Time, the parties

pursuant to its termination rights in Section 5.6(e), then LandCare shall
promptly, but in no event later than two business days after the date of such
termination, pay ServiceMaster an amount, not to exceed $1,000,000, equal to the

incurred since October 15, 1998, including negotiation and execution of this
Agreement and the attempted completion of the Merger, which fee and amount shall

EXHIBIT 2


                               VOTING AGREEMENT

         This Voting Agreement (this "Agreement") has been made as of November
1, 1998 (the "date hereof") by The ServiceMaster Company ("ServiceMaster") and
other parties who have executed this Agreement (herein called the
"Stockholders").

                                   RECITALS

         A. Concurrently with the execution and delivery of this Agreement,
ServiceMaster, SVM Acquisition Corporation, a wholly-owned subsidiary of
ServiceMaster ("Merger Subsidiary"), and LandCare USA, Inc. ("LandCare") are
entering into a Plan of Reorganization and Agreement and Plan of Merger of even
date herewith (which as constituted from time to time is herein called the
"Merger Agreement") which provides, among other things, that Merger Subsidiary
be merged into LandCare and that upon such Merger, LandCare will become a
wholly-owned subsidiary of ServiceMaster. The Merger Agreement also provides
that upon consummation of the Merger, each share of LandCare's Common Stock
outstanding immediately prior to consummation of the Merger will be converted
into a fraction of a share of Common Stock issuable by ServiceMaster. The term
"Merger" whenever it is used in this Agreement means the merger of the Merger
Subsidiary into LandCare.

         B. The Stockholders are the record and beneficial owners of the number
of shares of LandCare common stock set forth adjacent to the Stockholders'
signatures to this Agreement. The term "Stockholders' LandCare Shares" means the
shares of Common Stock listed adjacent to the Stockholders' signatures and any
other LandCare shares the Stockholders may acquire after the date hereof.

         C. The Stockholders have entered into this Agreement to induce
ServiceMaster to enter into the Merger Agreement.

THE PARTIES AGREE AS FOLLOWS:

         1. Agreement to Vote Shares.
            ------------------------

            (a) The Stockholders confirm that the Stockholders desire that the
Merger occur and have concluded that it is in the best interests of LandCare and
such Stockholders that LandCare's Board approve the Merger Agreement and that
LandCare sign the Merger Agreement and that it is better for LandCare to make
the commitments required by the Merger Agreement than to take the risk that by
seeking a higher offer for LandCare, the opportunity for acquisition by
ServiceMaster may be lost.

            (b) At every meeting of the stockholders of LandCare called with
respect to any of the following, and at every adjournment thereof, and on every
action or approval by written consent of the stockholders of LandCare with
respect to any of the following, the Stockholders irrevocably agree to vote the
Stockholders' LandCare Shares: (i) in favor of the adoption of the Merger
Agreement and approval of the Merger and any matter that could reasonably be
expected to 
<PAGE>
 
facilitate consummation of the Merger (the "Merger Proposal"); and (ii) against
approval of any proposal made in opposition to or competition with consummation
of the Merger and against any merger, consolidation, sale of assets,
reorganization or recapitalization, with any party other than with ServiceMaster
and its affiliates and against any reorganization, recapitalization, liquidation
or winding up of LandCare (each of the things cited in this clause (ii) is
hereinafter referred to as an "Opposing Proposal").

          (c) The voting commitments in this Section 1 and in Section 2
and the authorization in Section 3 shall end when and if (but not before) the
Merger Agreement shall be terminated in accordance with its terms.

     2.   No Support for Opposing Proposals.
          ---------------------------------

          (a) The Stockholders shall not invite or seek any Opposing Proposal,
support (or suggest that anyone else should support) any Opposing Proposal that
may be made, or ask LandCare's Board to consider, support or seek any Opposing
Proposal, or otherwise take any action designed to make any Opposing Proposal
more likely.

          (b) The Stockholders shall not meet or otherwise communicate with any
person that makes or is considering making an Opposing Proposal or any
representative of a person after becoming aware that the person has made or is
considering making a Opposing Proposal. The Stockholders shall promptly advise
ServiceMaster of each contact the Stockholders or any of the Stockholders'
representatives may receive from any person relating to any Opposing Proposal or
otherwise indicating that any person may wish to precipitate or engage in any
transaction arising out of any Opposing Proposal and will provide ServiceMaster
with all information ServiceMaster requests available to the Stockholders
regarding any Opposing Proposal or possible Opposing Proposal.

          (c) The Stockholders will not make any claim or join in any litigation
alleging that LandCare's Board is required to consider, endorse or Support any
Opposing Proposal or to invite or seek any Opposing Proposal.

          (d) The Stockholders shall not take any other action that is
reasonably likely to make consummation of the Merger less likely or to impair
ServiceMaster's ability to exercise any of the rights granted by this Agreement
or the value of any such exercise.

     3.   Authorization to Execute Ballot. The Stockholders hereby irrevocably
          --------------------------------
authorize ServiceMaster to execute as attorney in fact for the Stockholders any
ballot or consent form ServiceMaster shall reasonably deem appropriate to
accomplish the votes and consents required by this Agreement.

<PAGE>
 
     4.   Transfer Restrictions.
          ----------------------

          (a) Until and unless the Merger Agreement has been terminated (i) none
of the Stockholders' LandCare Shares shall be tendered in response to any tender
offer, (ii) no interest in any of the Stockholders' LandCare Shares shall be
sold or otherwise transferred, (iii) the Stockholders will not take any other
action which would impair Stockholders' ability to vote any of Stockholders'
LandCare Shares in the manner required by this Agreement and (iv) subject to
Section 11 hereof, the Stockholders' commitments in Sections 1 though 3 shall be
irrevocable.

          (b) The Stockholders hereby agree that for the period ending on the
first anniversary of the issuance of the Stockholders' LandCare Shares the
Stockholders shall not sell, offer to sell, or otherwise transfer or dispose of
any ServiceMaster shares received in the Merger in exchange for the
Stockholders' LandCare Shares (the "Stockholders' ServiceMaster Shares"), engage
in put, call, short-sale, straddle or similar transactions involving
ServiceMaster Shares, or in any other way reduce the Stockholders' risk of
owning Stockholders' ServiceMaster Shares, provided that this restriction shall
not prohibit the Stockholders from pledging Stockholders' ServiceMaster Shares
to secure full-recourse indebtedness. ServiceMaster shall be entitled to place a
legend on the certificates representing the Stockholders' ServiceMaster Shares
identifying the restrictions imposed by this paragraph.

          (c) The Stockholders hereby agree that Stockholders' LandCare Shares
shall be legended to reflect the restrictions set forth herein in form
reasonably satisfactory to ServiceMaster. Upon execution of this Agreement, the
Stockholders shall deliver their LandCare Shares to LandCare for placement of
the restrictive legend and the shares shall be promptly returned to the
Stockholders thereafter.

     5.   Representations and Warranties of the Stockholders.
          --------------------------------------------------

          (a) The Stockholders hereby warrant to ServiceMaster that the
Stockholders have the capacity to enter into this Agreement and the night and
power to perform their obligations under this Agreement.

          (b) The Stockholders are not subject to or obligated under any
provision of (i) their organizational documents (if the Stockholders are not a
natural person), (ii) any contract, license, franchise or permit, or (iii) any
order, judgment or decree which would be breached or violated by the execution,
delivery and performance of this Agreement by the Stockholders.

          (c) No authorization, consent or approval of, or any filing with, any
public body, court or authority is necessary for consummation by the
Stockholders of the transactions contemplated by this Agreement.

          (d) The Stockholders' LandCare Shares listed adjacent to the
Stockholders' signature to this Agreement constitute all of LandCare Common
Stock over which the Stockholders possess beneficial ownership or voting power
on the date of this Agreement. The Stockholders have absolute ownership of the
Stockholders' LandCare Shares free of any adverse interest and have 

                                       3

necessary and sufficient right and authority to make the commitments with
respect to the Stockholders' LandCare Shares contained in this Agreement.

          (e) The Stockholders are accredited investors as defined in the Rule
501 issued by the Securities and Exchange Commission under the Securities Act of

willing to respond to any questions or supply any information the Stockholders
shall desire in order to assess the risks and benefits of the transactions

execution of this Agreement.

     6.   Indemnification Currency. The Stockholders acknowledge that the
          ------------------------
Stockholders formerly had an ownership interest in a business enterprise
previously acquired by LandCare and that LandCare issued the Stockholders'
LandCare Shares in connection with LandCare's acquisition of that business. The
agreement pursuant to which that acquisition occurred (the "Prior Acquisition
Agreement") provides that the Stockholders have the right to deliver LandCare
shares in satisfaction for certain indemnification obligations of the
Stockholders that may arise under that Agreement. ServiceMaster hereby agrees
that after the Merger, the Stockholders may use ServiceMaster shares to satisfy
any indemnification obligations that the Stockholders may have under the Prior
Acquisition Agreement to the same extent that the Stockholders were permitted to
use LandCare shares prior to the Merger. The Stockholders hereby agree that the
Merger shall not limit or impair any indemnification obligation that the
Stockholders may have under the Prior Acquisition Agreement and hereby agree
that the provisions in the Prior Acquisition Agreement that permit the
Stockholders to utilize LandCare shares to satisfy, any certain indemnification
obligations that may arise under the Prior Acquisition Agreement shall be deemed
after the Merger to refer to ServiceMaster shares.

     7.   Further Assurances. The Stockholders will, upon the request of
          ------------------
ServiceMaster, execute and deliver such documents and take such action
reasonably deemed by ServiceMaster to be necessary or desirable to more

EXHIBIT 3


                               VOTING AGREEMENT

         This Voting Agreement (this "Agreement") has been made as of November
1, 1998 (the "date hereof") by The ServiceMaster Company ("ServiceMaster") and
other party who has executed this Agreement (herein called the "Stockholder").

                                   RECITALS

          A.   Concurrently with the execution and delivery of this Agreement,
ServiceMaster, SVM Acquisition Corporation, a wholly-owned subsidiary of
ServiceMaster ("Merger Subsidiary"), and LandCare USA, Inc. ("LandCare") are
entering into a Plan of Reorganization and Agreement and Plan of Merger of even
date herewith (which as constituted from time to time is herein called the
"Merger Agreement") which provides, among other things, that Merger Subsidiary
be merged into LandCare and that upon such Merger, LandCare will become a
wholly-owned subsidiary of ServiceMaster. The Merger Agreement also provides
that upon consummation of the Merger, each share of LandCare's Common Stock
outstanding immediately prior to consummation of the Merger will be converted
into a fraction of a share of Common Stock issuable by ServiceMaster. The term
"Merger" whenever it is used in this Agreement means the merger of the Merger
Subsidiary into LandCare.

          B.   The Stockholder is the record and beneficial owner of the number
of shares of LandCare common stock set forth adjacent to the Stockholder's
signatures to this Agreement. The term "Stockholder's LandCare Shares" means the
shares of Common Stock listed adjacent to the Stockholder's signature and any
other LandCare shares the Stockholder may acquire after the date hereof.

          C.   The Stockholder has entered into this Agreement to induce
ServiceMaster to enter into the Merger Agreement.

THE PARTIES AGREE AS FOLLOWS:

          1.   Agreement to Vote Shares.
               ------------------------  

               (a) The Stockholder confirms that the Stockholder desires that
the Merger occur and has concluded that it is in the best interests of LandCare
and such Stockholder that LandCare's Board approve the Merger Agreement and that
LandCare sign the Merger Agreement and that it is better for LandCare to make
the commitments required by the Merger Agreement than to take the risk that by
seeking a higher offer for LandCare, the opportunity for acquisition by
ServiceMaster may be lost.

               (b) At every meeting of the Stockholders of LandCare called
with respect to any of the following, and at every adjournment thereof, and on
every action or approval by written consent of the Stockholders of LandCare with
respect to any of the following, the Stockholder irrevocably agrees to vote the
Stockholders' LandCare Shares: (i) in favor of the adoption of the Merger
Agreement and approval of the Merger and any matter that could reasonably be
expected to 

                                       1
<PAGE>
 
facilitate consummation of the Merger (the "Merger Proposal"); and (ii) against
approval of any proposal made in opposition to or competition with consummation
of the Merger and against any merger, consolidation, sale of assets,
reorganization or recapitalization, with any party other than with ServiceMaster
and its affiliates and against any reorganization, recapitalization, liquidation
or winding up of LandCare (each of the things cited in this clause (ii) is
hereinafter referred to as an "Opposing Proposal").

               (c) The voting commitments in this Section 1 and in Section 2
and the authorization in Section 3 shall end when and if (but not before) the
Merger Agreement shall be terminated in accordance with its terms.

         2.    No Support for Opposing Proposals.
               ---------------------------------

               (a) The Stockholders shall not invite or seek any Opposing
Proposal, support (or suggest that anyone else should support) any Opposing
Proposal that may be made, or ask LandCare's Board to consider, support or seek
any Opposing Proposal, or otherwise take any action designed to make any
Opposing Proposal more likely.

               (b) The Stockholder shall not meet or otherwise communicate
with any person that makes or is considering making an Opposing Proposal or any
representative of a person after becoming aware that the person has made or is
considering making a Opposing Proposal. The Stockholder shall promptly advise
ServiceMaster of each contact the Stockholder or any of the Stockholder's
representatives may receive from any person relating to any Opposing Proposal or
otherwise indicating that any person may wish to precipitate or engage in any
transaction arising out of any Opposing Proposal and will provide ServiceMaster
with all information ServiceMaster requests available to the Stockholders
regarding any Opposing Proposal or possible Opposing Proposal.

               (c) The Stockholder will not make any claim or join in any
litigation alleging that LandCare's Board is required to consider, endorse or
Support any Opposing Proposal or to invite or seek any Opposing Proposal.

               (d) The Stockholder shall not take any other action that is
reasonably likely to make consummation of the Merger less likely or to impair
ServiceMaster's ability to exercise any of the rights granted by this Agreement
or the value of any such exercise.

         3.    Authorization to Execute Ballot. The Stockholder hereby
               -------------------------------
irrevocably authorizes ServiceMaster to execute as attorney in fact for the
Stockholder any ballot or consent form ServiceMaster shall reasonably deem
appropriate to accomplish the votes and consents required by this Agreement.

                                       2
<PAGE>
 
          4.   Transfer Restrictions.
               ---------------------

               (a) Until and unless the Merger Agreement has been terminated
(i) none of the Stockholder's LandCare Shares shall be tendered in response to
any tender offer, (ii) no interest in any of the Stockholder's LandCare Shares
shall be sold or otherwise transferred, (iii) the Stockholder will not take any
other action which would impair Stockholder's ability to vote any of
Stockholder's LandCare Shares in the manner required by this Agreement and (iv)
subject to Section 11 hereof, the Stockholder's commitments in Sections 1 though
3 shall be irrevocable.

               (b) The Stockholder hereby agrees that for the period ending
on the first anniversary of the issuance of the Stockholder's LandCare Shares
the Stockholder shall not sell, offer to sell, or otherwise transfer or dispose
of any ServiceMaster shares received in the Merger in exchange for the
Stockholder's LandCare Shares (the "Stockholder's ServiceMaster Shares"), engage
in put, call, short-sale, straddle or similar transactions involving
ServiceMaster Shares, or in any other way reduce the Stockholder's risk of
owning Stockholder's ServiceMaster Shares, provided that this restriction shall
not prohibit the Stockholders from pledging Stockholders' ServiceMaster Shares
to secure full-recourse indebtedness. ServiceMaster shall be entitled to place a
legend on the certificates representing the Stockholder's ServiceMaster Shares
identifying the restrictions imposed by this paragraph.

               (c) The Stockholder hereby agree that Stockholder's LandCare
Shares shall be legended to reflect the restrictions set forth herein in form
reasonably satisfactory to ServiceMaster. Upon execution of this Agreement, the
Stockholder shall deliver their LandCare Shares to LandCare for placement of the
restrictive legend and the shares shall be promptly returned to the Stockholder
thereafter.

          5.   Representations and Warranties of the Stockholder.
               -------------------------------------------------

               (a) The Stockholder hereby warrants to ServiceMaster that the
Stockholder have the capacity to enter into this Agreement and the night and
power to perform their obligations under this Agreement.

               (b) The Stockholder is not subject to or obligated under any
provision of (i) its organizational documents (if the Stockholders are not a
natural person), (ii) any contract, license, franchise or permit, or (iii) any
order, judgment or decree which would be breached or violated by the execution,
delivery and performance of this Agreement by the Stockholder.

               (c) No authorization, consent or approval of, or any filing
with, any public body, court or authority is necessary for consummation by the
Stockholder of the transactions contemplated by this Agreement.

               (d) The Stockholder's LandCare Shares listed adjacent to the
Stockholder's signature to this Agreement constitute all of LandCare Common
Stock over which the Stockholder possesses beneficial ownership or voting power
on the date of this Agreement. The Stockholder has absolute ownership of the
Stockholder's LandCare Shares free of any adverse interest and has 

                                       3

necessary and sufficient right and authority to make the commitments with
respect to the Stockholder's LandCare Shares contained in this Agreement.

               (e) The Stockholder is an accredited investors as defined in
the Rule 501 issued by the Securities and Exchange Commission under the
Securities Act of 1933, as amended, and is an affiliate of LandCare. The
Stockholder is able to assess the risks and benefits of the transactions

and LandCare are each willing to respond to any questions or supply any
information the Stockholder shall desire in order to assess the risks and
benefits of the transactions contemplated by this Agreement and hereby confirm
that there are no questions that the Stockholder desires to ask or information
the Stockholder desires to obtain that has not been answered or supplied prior

          6.   Indemnification Currency. The Stockholder acknowledges that the
               ------------------------
Stockholder formerly had an ownership interest in a business enterprise
previously acquired by LandCare and that LandCare issued the Stockholder's
LandCare Shares in connection with LandCare's acquisition of that business. The
agreement pursuant to which that acquisition occurred (the "Prior Acquisition
Agreement") provides that the Stockholder has the right to deliver LandCare
shares in satisfaction for certain indemnification obligations of the
Stockholder that may arise under that Agreement. ServiceMaster hereby agrees
that after the Merger, the Stockholder may use ServiceMaster shares to satisfy
any indemnification obligations that the Stockholder may have under the Prior
Acquisition Agreement to the same extent that the Stockholder was permitted to
use LandCare shares prior to the Merger. The Stockholder hereby agrees that the
Merger shall not limit or impair any indemnification obligation that the
Stockholder may have under the Prior Acquisition Agreement and hereby agrees
that the provisions in the Prior Acquisition Agreement that permit the
Stockholder to utilize LandCare shares to satisfy, any certain indemnification
obligations that may arise under the Prior Acquisition Agreement shall be deemed
after the Merger to refer to ServiceMaster shares.

          7.   Further Assurances. The Stockholder will, upon the request of
               ------------------
ServiceMaster, execute and deliver such documents and take such action
reasonably deemed by ServiceMaster to be necessary or desirable to more

Agreement.

               --------

incurring such expenses.

amended, altered or supplemented except by a writing signed by ServiceMaster and
the Stockholder. Neither the Stockholder nor ServiceMaster may assign any of its
rights or obligations under this Agreement without the written consent of the
other.

EXHIBIT 4


                               VOTING AGREEMENT

         This Voting Agreement (this "Agreement") has been made as of November
1, 1998 (the "date hereof") by The ServiceMaster Company ("ServiceMaster") and
other party who has executed this Agreement (herein called the "Stockholder").

                                   RECITALS

          A.   Concurrently with the execution and delivery of this Agreement,
ServiceMaster, SVM Acquisition Corporation, a wholly-owned subsidiary of
ServiceMaster ("Merger Subsidiary"), and LandCare USA, Inc. ("LandCare") are
entering into a Plan of Reorganization and Agreement and Plan of Merger of even
date herewith (which as constituted from time to time is herein called the
"Merger Agreement") which provides, among other things, that Merger Subsidiary
be merged into LandCare and that upon such Merger, LandCare will become a
wholly-owned subsidiary of ServiceMaster. The Merger Agreement also provides
that upon consummation of the Merger, each share of LandCare's Common Stock
outstanding immediately prior to consummation of the Merger will be converted
into a fraction of a share of Common Stock issuable by ServiceMaster. The term
"Merger" whenever it is used in this Agreement means the merger of the Merger
Subsidiary into LandCare.

          B.   The Stockholder is the record and beneficial owner of the number
of shares of LandCare common stock set forth adjacent to the Stockholder's
signatures to this Agreement. The term "Stockholder's LandCare Shares" means the
shares of Common Stock listed adjacent to the Stockholder's signature and any
other LandCare shares the Stockholder may acquire after the date hereof.

          C.   The Stockholder has entered into this Agreement to induce
ServiceMaster to enter into the Merger Agreement.

THE PARTIES AGREE AS FOLLOWS:

          1.   Agreement to Vote Shares.
               ------------------------  

               (a) The Stockholder confirms that the Stockholder desires that
the Merger occur and has concluded that it is in the best interests of LandCare
and such Stockholder that LandCare's Board approve the Merger Agreement and that
LandCare sign the Merger Agreement and that it is better for LandCare to make
the commitments required by the Merger Agreement than to take the risk that by
seeking a higher offer for LandCare, the opportunity for acquisition by
ServiceMaster may be lost.

               (b) At every meeting of the Stockholders of LandCare called
with respect to any of the following, and at every adjournment thereof, and on
every action or approval by written consent of the Stockholders of LandCare with
respect to any of the following, the Stockholder irrevocably agrees to vote the
Stockholders' LandCare Shares: (i) in favor of the adoption of the Merger
Agreement and approval of the Merger and any matter that could reasonably be
expected to 

                                       1
<PAGE>
 
facilitate consummation of the Merger (the "Merger Proposal"); and (ii) against
approval of any proposal made in opposition to or competition with consummation
of the Merger and against any merger, consolidation, sale of assets,
reorganization or recapitalization, with any party other than with ServiceMaster
and its affiliates and against any reorganization, recapitalization, liquidation
or winding up of LandCare (each of the things cited in this clause (ii) is
hereinafter referred to as an "Opposing Proposal").

               (c) The voting commitments in this Section 1 and in Section 2
and the authorization in Section 3 shall end when and if (but not before) the
Merger Agreement shall be terminated in accordance with its terms.

         2.    No Support for Opposing Proposals.
               ---------------------------------

               (a) The Stockholders shall not invite or seek any Opposing
Proposal, support (or suggest that anyone else should support) any Opposing
Proposal that may be made, or ask LandCare's Board to consider, support or seek
any Opposing Proposal, or otherwise take any action designed to make any
Opposing Proposal more likely.

               (b) The Stockholder shall not meet or otherwise communicate
with any person that makes or is considering making an Opposing Proposal or any
representative of a person after becoming aware that the person has made or is
considering making a Opposing Proposal. The Stockholder shall promptly advise
ServiceMaster of each contact the Stockholder or any of the Stockholder's
representatives may receive from any person relating to any Opposing Proposal or
otherwise indicating that any person may wish to precipitate or engage in any
transaction arising out of any Opposing Proposal and will provide ServiceMaster
with all information ServiceMaster requests available to the Stockholders
regarding any Opposing Proposal or possible Opposing Proposal.

               (c) The Stockholder will not make any claim or join in any
litigation alleging that LandCare's Board is required to consider, endorse or
Support any Opposing Proposal or to invite or seek any Opposing Proposal.

               (d) The Stockholder shall not take any other action that is
reasonably likely to make consummation of the Merger less likely or to impair
ServiceMaster's ability to exercise any of the rights granted by this Agreement
or the value of any such exercise.

         3.    Authorization to Execute Ballot. The Stockholder hereby
               -------------------------------
irrevocably authorizes ServiceMaster to execute as attorney in fact for the
Stockholder any ballot or consent form ServiceMaster shall reasonably deem
appropriate to accomplish the votes and consents required by this Agreement.

          4.   Transfer Restrictions.
               ---------------------

               (a) Until and unless the Merger Agreement has been terminated
(i) none of the Stockholder's LandCare Shares shall be tendered in response to
any tender offer, (ii) no interest in 

                                       2
<PAGE>
 
any of the Stockholder's LandCare Shares shall be sold or otherwise transferred,
(iii) the Stockholder will not take any other action which would impair
Stockholder's ability to vote any of Stockholder's LandCare Shares in the manner
required by this Agreement and (iv) subject to Section 11 hereof, the
Stockholder's commitments in Sections 1 though 3 shall be irrevocable.

               (b) The Stockholder hereby agree that Stockholder's LandCare
Shares shall be legended to reflect the restrictions set forth herein in form
reasonably satisfactory to ServiceMaster. Upon execution of this Agreement, the
Stockholder shall deliver their LandCare Shares to LandCare for placement of the
restrictive legend and the shares shall be promptly returned to the Stockholder
thereafter.

          5.   Representations and Warranties of the Stockholder.
               -------------------------------------------------

               (a) The Stockholder hereby warrants to ServiceMaster that the
Stockholder have the capacity to enter into this Agreement and the night and
power to perform their obligations under this Agreement.

               (b) The Stockholder is not subject to or obligated under any
provision of (i) its organizational documents (if the Stockholders are not a
natural person), (ii) any contract, license, franchise or permit, or (iii) any
order, judgment or decree which would be breached or violated by the execution,
delivery and performance of this Agreement by the Stockholder.

such Stockholder that LandCare's Board approve the Merger Agreement and that

facilitate consummation of the Merger (the "Merger Proposal"); and (ii) against
approval of any proposal made in opposition to or competition with consummation
of the Merger and against any merger, consolidation, sale of assets,
reorganization or recapitalization with any party other than with ServiceMaster
and its affiliates and against any reorganization, recapitalization, liquidation
or winding up of LandCare (each of the things cited in this clause (ii) is
hereinafter referred to as an "Opposing Proposal").

be merged into LandCare and that upon such Merger, LandCare will become a

that upon consummation of the Merger, each share of LandCare's Common Stock
outstanding immediately prior to consummation of the Merger will be converted
into a fraction of a share of Common Stock issuable by ServiceMaster. The term
"Merger" whenever it is used in this Agreement means the merger of the Merger
Subsidiary into LandCare.

                               VOTING AGREEMENT

         This Voting Agreement (this "Agreement") has been made as of November
1, 1998 (the "date hereof") by The ServiceMaster Company ("ServiceMaster") and
other party who has executed this Agreement (herein called the "Stockholder").

                                   RECITALS

         A.    Concurrently with the execution and delivery of this Agreement,
ServiceMaster, SVM Acquisition Corporation, a wholly-owned subsidiary of
ServiceMaster ("Merger Subsidiary"), and LandCare USA, Inc. ("LandCare") are
entering into a Plan of Reorganization and Agreement and Plan of Merger of even
date herewith (which as constituted from time to time is herein called the
"Merger Agreement") which provides, among other things, that Merger Subsidiary
be merged into LandCare and that upon such Merger, LandCare will become a
wholly-owned subsidiary of ServiceMaster. The Merger Agreement also provides
that upon consummation of the Merger, each share of LandCare's Common Stock
outstanding immediately prior to consummation of the Merger will be converted
into a fraction of a share of Common Stock issuable by ServiceMaster. The term
"Merger" whenever it is used in this Agreement means the merger of the Merger
Subsidiary into LandCare.

         B.    The Stockholder is the record and beneficial owner of the number
of shares of LandCare common stock set forth adjacent to the Stockholder's
signature to this Agreement. The term "Stockholder's LandCare Shares" means the
shares of Common Stock listed adjacent to the Stockholder's signature and any
other LandCare shares the Stockholder may acquire after the date hereof.

         C.    The Stockholder has entered into this Agreement to induce
ServiceMaster to enter into the Merger Agreement.

THE PARTIES AGREE AS FOLLOWS:

         1.    Agreement to Vote Shares.
               ------------------------

               (a)  The Stockholder confirms that the Stockholder desires that
the Merger occur and has concluded that it is in the best interests of LandCare
and such Stockholder that LandCare's Board approve, the Merger Agreement and
that LandCare sign the Merger Agreement and that it is better for LandCare to
make the commitments required by the Merger Agreement than to take the risk that
by seeking a higher offer for LandCare, the opportunity for acquisition by
ServiceMaster may be lost.

               (b)  At every meeting of the Stockholders of LandCare called
with respect to any of the following, and at every adjournment thereof, and on
every action or approval by written consent of the Stockholders of LandCare with
respect to any of the following, the Stockholder irrevocably agrees to vote the
Stockholder's LandCare Shares: (i) in favor of the adoption of the Merger
Agreement and approval of the Merger and any matter that could reasonably be
expected to 

                                       1
<PAGE>
 
facilitate consummation of the Merger (the "Merger Proposal"); and (ii) against
approval of any proposal made in opposition to or competition with consummation
of the Merger and against any merger, consolidation, sale of assets,
reorganization or recapitalization with any party other than with ServiceMaster
and its affiliates and against any reorganization, recapitalization, liquidation
or winding up of LandCare (each of the things cited in this clause (ii) is
hereinafter referred to as an "Opposing Proposal").

               (c)  The voting commitments in this Section 1 and in Section 2
and the authorization in Section 3 shall end when and if (but not before) the
Merger Agreement shall be terminated in accordance with its terms.

          2.   No Support for Opposing Proposals.
               ---------------------------------

               (a)  The Stockholder shall not invite or seek any Opposing
Proposal, support (or suggest that anyone else should support) any Opposing
Proposal that may be made, or ask LandCare's Board to consider, support or seek
any Opposing Proposal, or otherwise take any action designed to make any
Opposing Proposal more likely.

               (b)  The Stockholder shall not meet or otherwise communicate
with any person that makes or is considering making an Opposing Proposal or any
representative of a person after becoming aware that the person has made or is
considering making a Opposing Proposal. The Stockholder shall promptly advise
ServiceMaster of each contact the Stockholder or any of the Stockholder is
representatives may receive from any person relating to any Opposing Proposal or
otherwise indicating that any person may wish to precipitate or engage in any
transaction arising out of any Opposing Proposal and will provide ServiceMaster
with all information ServiceMaster requests available to the Stockholder
regarding any Opposing Proposal or possible Opposing Proposal.

               (c)  The Stockholder will not make any claim or join in any
litigation alleging that LandCare's Board is required to consider, endorse or
support any Opposing Proposal or to invite or seek any Opposing Proposal.

               (d)  The Stockholder shall not take any other action that is
likely to make consummation of the Merger less likely or to impair
ServiceMaster's ability to exercise any of the rights granted by this Agreement
or the value of any such exercise.

          3.   Authorization to Execute Ballot. The Stockholder hereby
               -------------------------------
irrevocably authorizes ServiceMaster to execute as attorney in fact for the
Stockholder any ballot or consent form ServiceMaster shall reasonably deem
appropriate to accomplish the votes and consents required by this Agreement.

          4.   Transfer Restrictions.
               ---------------------

(i) none of the Stockholder's LandCare Shares shall be tendered in response to
any tender offer, (ii) no interest in 

                                       2
<PAGE>
 
any of the Stockholder's LandCare Shares shall be sold or otherwise transferred,
(iii) the Stockholder will not take any other action which would impair
Stockholder's ability to vote any of Stockholder's LandCare Shares in the manner
required by this Agreement and (iv) subject to Section 11 hereof, the
Stockholder's commitments in Sections 1 though 3 shall be irrevocable.

               (b)  The Stockholder hereby agrees that for the period ending
on the first anniversary of the issuance of the Stockholder's LandCare Shares
the Stockholder shall not sell, offer to sell, or otherwise transfer or dispose
of any ServiceMaster shares received in the Merger in exchange for the
Stockholder's LandCare Shares (the "Stockholder's ServiceMaster Shares"), engage
in put, call, short-sale, straddle or similar transactions involving
ServiceMaster Shares, or in any other way reduce the Stockholder's risk of
owning Stockholder's ServiceMaster Shares, provided that this restriction shall
not prohibit the Stockholder from pledging Stockholder's ServiceMaster Shares to
secure full-recourse indebtedness. ServiceMaster shall be entitled to place a
legend on the certificates representing the Stockholder's ServiceMaster Shares
identifying the restrictions imposed by this paragraph.

               (c)  The Stockholder hereby agrees that Stockholder's LandCare
Shares shall be legended to reflect the restrictions set forth herein in form
reasonably satisfactory to ServiceMaster. Upon execution of this Agreement, the
Stockholder shall deliver its LandCare Shares to LandCare for placement of the
restrictive legend and the shares shall be promptly returned to the Stockholder
thereafter.

          5.   Representations and Warranties of the Stockholder.
               -------------------------------------------------

               (a)  The Stockholder hereby warrants to ServiceMaster that the
Stockholder has the capacity to enter into this Agreement and the right and
power to perform his obligations under this Agreement.

               (b)  The Stockholder is not subject to or obligated under any
provision of (i) its organizational documents (if the Stockholder is not a
natural person), (ii) any contract, license, franchise or permit, or (iii) any
order, judgment or decree which would be breached or violated by the execution,
delivery and performance of this Agreement by the Stockholder.

               (c)  No authorization, consent or approval of, or any filing
with, any public body, court or authority is necessary for consummation by the
Stockholder of the transactions contemplated by this Agreement.

               (d)  The Stockholder's LandCare Shares listed adjacent to the
Stockholder's signature to this Agreement constitute all of LandCare Common
Stock over which the Stockholder possesses beneficial ownership or voting power
on the date of this Agreement. The Stockholder has absolute ownership of the
Stockholder's LandCare Shares free of any adverse interest and has necessary and
sufficient right and authority to make the commitments with respect to the
Stockholder's LandCare Shares contained in this Agreement.

                                       3
<PAGE>
 
               (e)  The Stockholder is an accredited investor as defined in
the Rule 501 issued by the Securities and Exchange Commission under the
Securities Act of 1933, as amended, and is an affiliate of LandCare. The
Stockholder is able to assess the risks and benefits of the transactions
contemplated by this Agreement. The Stockholder understands that ServiceMaster
and LandCare are each willing to respond to any questions or supply any
information the Stockholder shall desire in order to assess the risks and
benefits of the transactions contemplated by this Agreement and hereby confirms
that there are no questions that the Stockholder desires to ask or information
the Stockholder desires to obtain that has not been answered or supplied prior
to the Stockholder's execution of this Agreement.

          6.   Indemnification Currency. The Stockholder acknowledges that the
               ------------------------
Stockholder formerly had any ownership interest in a business enterprise
previously acquired by LandCare and that LandCare issued the Stockholder's
LandCare Shares in connection with LandCare's acquisition of that business. The
agreement pursuant to which that acquisition occurred (the "Prior Acquisition
Agreement"), provides that the Stockholder has the right to deliver LandCare
shares in satisfaction for certain indemnification obligations of the
Stockholder that may arise under that Agreement. ServiceMaster hereby agrees
that after the Merger, the Stockholder may use ServiceMaster shares to satisfy
any indemnification obligations that the Stockholder may have under the Prior
Acquisition Agreement to the same extent that the Stockholder was permitted to
use LandCare shares prior to the Merger. The Stockholder hereby agrees that the
Merger shall not limit or impair any indemnification obligation that the
Stockholder may have under the Prior Acquisition Agreement and hereby agrees
that the provisions in the Prior Acquisition Agreement that permit the
Stockholder to utilize LandCare shares to satisfy any certain indemnification
obligations that may arise under the Prior Acquisition Agreement shall be deemed
after the Merger to refer to ServiceMaster shares.

          7.   Further Assurances. The Stockholder will, upon the request of
               ------------------
ServiceMaster, execute and deliver such documents and take such action
reasonably deemed by ServiceMaster to be necessary or desirable to more
effectively complete and evidence the transactions contemplated by this
Agreement.

          8.   Expenses. All costs and expenses incurred in connection with this
               --------
Agreement and the transactions contemplated hereby shall be paid by the party
incurring such expenses.

          9.   Amendment; Assignment. This Agreement may not be modified,
               ---------------------
amended, altered or supplemented except by a writing signed by ServiceMaster and
the Stockholder. Neither the Stockholder nor ServiceMaster may assign any of its
rights or obligations under this Agreement without the written consent of the
other.

          10.  Notices. All notices, requests, claims, demands and other
               -------

entitled to enforce its rights under this Agreement specifically, to recover

                               VOTING AGREEMENT

         This Voting Agreement (this "Agreement") has been made as of November
1, 1998 (the "date hereof') by The ServiceMaster Company ("ServiceMaster") and
other party who has executed this Agreement (herein called the "Stockholder").

                                   RECITALS

         A. Concurrently with the execution and delivery of this Agreement,
ServiceMaster, SVM Acquisition Corporation, a wholly-owned subsidiary of
ServiceMaster ("Merger Subsidiary"), and LandCare USA, Inc. ("LandCare") are
entering into a Plan of Reorganization and Agreement and Plan of Merger of even
date herewith (which as constituted from time to time is herein called the
"Merger Agreement") which provides, among other things, that Merger Subsidiary
be merged into LandCare and that upon such Merger, LandCare will become a
wholly-owned subsidiary of ServiceMaster. The Merger Agreement also provides
that upon consummation of the Merger, each share of LandCare's Common Stock
outstanding immediately prior to consummation of the Merger will be converted
into a fraction of a share of Common Stock issuable by ServiceMaster. The term
"Merger" whenever it is used in this Agreement means the merger of the Merger
Subsidiary into LandCare.

         B. The Stockholder is the record and beneficial owner of the number of
shares of LandCare common stock set forth adjacent to the Stockholder's
signature to this Agreement. The term "Stockholder's LandCare Shares" means the
shares of Common Stock listed adjacent to the Stockholder's signature and any
other LandCare shares the Stockholder may acquire after the date hereof.

         C. The Stockholder has entered into this Agreement to induce
ServiceMaster to enter into the Merger Agreement.

THE PARTIES AGREE AS FOLLOWS:

         1. Agreement to Vote Shares.

            (a) The Stockholder confirms that the Stockholder desires that the
Merger occur and has concluded that it is in the best interests of LandCare and
such Stockholder that LandCare's Board approve the Merger Agreement and that
LandCare sign the Merger Agreement and that it is better or LandCare to make the
commitments required by the Merger Agreement than to take the risk that by
seeking a higher offer for LandCare, the opportunity for acquisition by
ServiceMaster may be lost.

            (b) At every meeting of the Stockholders of LandCare called with
respect to any of the following, and at every adjournment thereof, and on every
action or approval by written consent of the Stockholders of LandCare with
respect to any of the following, the Stockholder irrevocably agrees to vote the
Stockholder's LandCare Shares: (i) in favor of the adoption of the Merger
Agreement and approval of the Merger and any matter that could reasonably be
expected to 

                                       1
<PAGE>
 
facilitate consummation of the Merger (the "Merger Proposal"); and (ii) against
approval of any proposal made in opposition to or competition with consummation
of the Merger and against any merger, consolidation, sale of assets,
reorganization or recapitalization with any party other than with ServiceMaster
and its affiliates and against any reorganization, recapitalization, liquidation
or winding up of LandCare (each of the things cited in this clause (ii) is
hereinafter referred to as an "Opposing Proposal").

            (c) The voting commitments in this Section 1 and in Section 2 and
the authorization in Section 3 shall end when and if (but not before) the Merger
Agreement shall be terminated in accordance with its terms.

            ---------------------------------

            (a) The Stockholder shall not invite or seek any Opposing Proposal,

Proposal, or otherwise take any action designed to make any Opposing Proposal
more likely.

            (b) The Stockholder shall not meet or otherwise communicate with any
person that makes or is considering making an Opposing Proposal or any
representative of a person after becoming aware that the person has made or is
considering making a Opposing Proposal. The Stockholder shall promptly advise
ServiceMaster of each contact the Stockholder or any of the Stockholder's
representatives may receive from any person relating to any Opposing Proposal or
otherwise indicating that any person may wish to precipitate or engage in any
transaction arising out of any Opposing Proposal and will provide ServiceMaster
with all information ServiceMaster requests available to the Stockholder
regarding any Opposing Proposal or possible Opposing Proposal.

            (c) The Stockholder will not make any claim or join in any
litigation alleging that LandCare's Board is required to consider, endorse or
support any Opposing Proposal or to invite or seek any Opposing Proposal.

            (d) The Stockholder shall not take any other action that is
reasonably likely to make consummation of the Merger less likely or to impair
ServiceMaster's ability to exercise any of the rights granted by this Agreement
or the value of any such exercise.

         3. Authorization to Execute Ballot. The Stockholder hereby irrevocably
            -------------------------------
authorizes ServiceMaster to execute as attorney in fact for the Stockholder any
ballot or consent form ServiceMaster shall reasonably deem appropriate to
accomplish the votes and consents required by this Agreement.

         4. Transfer Restrictions.
            ---------------------

<PAGE>
 
any of the Stockholder's LandCare Shares shall be sold or otherwise transferred,
(iii) the Stockholder will not take any other action which would impair
Stockholder's ability to vote any of Stockholder's Shares in the manner required
by this Agreement and (iv) subject to Section 11 hereof, the Stockholder's
commitments in Sections 1 though 3 shall be irrevocable.

            (b) The Stockholder hereby agrees that for the period ending on the
first anniversary of the issuance of the Stockholder's LandCare Shares the
Stockholder shall not sell, offer to sell, or otherwise transfer or dispose of
any ServiceMaster shares received in the Merger in exchange for the
Stockholder's LandCare Shares (the "Stockholder's ServiceMaster Shares"), engage
in put, call, short-sale, straddle or similar transactions involving
ServiceMaster Shares, or in any other way reduce the Stockholder's risk of
owning Stockholder's ServiceMaster Shares, provided that this restriction shall
not prohibit the Stockholder from pledging Stockholder's ServiceMaster Shares to
secure full-recourse indebtedness. ServiceMaster shall be entitled to place a
legend on the certificates representing the Stockholder's ServiceMaster Shares
identifying the restrictions imposed by this paragraph.

            (c) The Stockholder hereby agrees that Stockholder's LandCare
Shares shall be legended to reflect the restrictions set forth herein in form
reasonably satisfactory to ServiceMaster. Upon execution of this Agreement, the
Stockholder shall deliver its LandCare Shares to LandCare for placement of the
restrictive legend and the shares shall be promptly returned to the Stockholder

EXHIBIT 10

                               VOTING AGREEMENT

     This Voting Agreement (this "Agreement") has been made as of November 1,
1998 (the "date hereof') by The ServiceMaster Company ("ServiceMaster") and
other party who has executed this Agreement (herein called the "Stockholder").

                                   RECITALS

     A.   Concurrently with the execution and delivery of this Agreement,
ServiceMaster, SVM Acquisition Corporation. a wholly-owned subsidiary of
ServiceMaster ("Merger Subsidiary"), and LandCare USA, Inc. ("LandCare") are
entering 'into a Plan of Reorganization and Agreement and Plan of Merger of even
date herewith (which as constituted from time to time is herein called the
"Merger Agreement") which provides, among other things, that Merger Subsidiary
be merged into LandCare and that upon such Merger, LandCare will become a
wholly-owned subsidiary of ServiceMaster. The Merger Agreement also provides
that upon consummation of the Merger, each share of LandCare's Common Stock
outstanding immediately prior to consummation of the Merger will be converted
into a fraction of a share of Common Stock issuable by ServiceMaster. The term
"Merger" whenever it is used in this Agreement means the merger of the Merger
Subsidiary into LandCare.

     B.   The Stockholder is the record and beneficial owner of the number of
shares of LandCare common stock set forth adjacent to the Stockholder's
signature to this Agreement. The term "Stockholder's LandCare Shares" means the
shares of Common Stock listed adjacent to the Stockholder's signature and any
other LandCare shares the Stockholder may acquire after the date hereof.

     C.   The Stockholder has entered into this Agreement to induce
ServiceMaster to enter into the Merger Agreement.


THE PARTIES AGREE AS FOLLOWS:

     1.   Agreement to Vote Shares.
          ------------------------

          (a)  The Stockholder confirm that the Stockholder desires that the
Merger occur and has concluded that it is in the best interests of LandCare and
such Stockholder that LandCare's Board approve the Merger Agreement and that
LandCare sign the Merger Agreement and that it is better for LandCare to make
the commitments required by the Merger Agreement than to take the risk that by
seeking a higher offer for LandCare, the opportunity for acquisition by
ServiceMaster may be lost.

          (b)  At every meeting of the Stockholders of LandCare called with
respect to any of the following, and at every adjournment thereof, and on every
action or approval by written consent of the Stockholders of LandCare with
respect to any of the following, the Stockholder irrevocably agrees to vote the
Stockholder's LandCare Shares: (i) in favor of the adoption of the Merger
Agreement and approval of the Merger and any matter that could reasonably be
expected to

                                       1
<PAGE>
 
facilitate consummation of the Merger (the "Merger Proposal"); and (ii) against
approval of any proposal made in opposition to or competition with consummation
of the Merger and against any merger, consolidation, sale of assets,
reorganization or recapitalization with any party other than with ServiceMaster
and its affiliates and against any reorganization, recapitalization, liquidation
or winding up of LandCare (each of the things cited in this clause (ii) is
hereinafter referred to as an "Opposing Proposal").

          (c)  The voting commitments in this Section 1 and in Section 2 and the
authorization in Section 3 shall end when and if (but not before) the Merger
Agreement shall be terminated in accordance with its terms.

     2.   No Support for Opposing Proposals.
          ---------------------------------

          (a)  The Stockholder shall not invite or seek any Opposing Proposal,
support (or suggest that anyone else should support) any Opposing Proposal that
may be made, or ask LandCare's Board to consider, support or seek any Opposing
Proposal, or otherwise take any action designed to make any Opposing Proposal
more likely.

          (b)  The Stockholder shall not meet or otherwise communicate with any
person that makes or is considering making an Opposing Proposal or any
representative of a person after becoming aware that the person has made or is
considering making a Opposing Proposal. The Stockholder shall promptly advise
ServiceMaster of each contact the Stockholder or any of the Stockholder's
representatives may receive from any person relating to any Opposing Proposal or
otherwise indicating that any person may wish to precipitate or engage in any
transaction arising out of any Opposing Proposal and will provide ServiceMaster
with all information ServiceMaster requests available to the Stockholder
regarding any Opposing Proposal or possible Opposing Proposal.

          (c)  The Stockholder will not make any claim or join in any litigation
alleging that LandCare's Board is required to consider, endorse or support any
Opposing Proposal or to invite or seek any Opposing Proposal.

          (d)  The Stockholder shall not take any other action that is
reasonably likely to make consummation of the Merger less likely or to impair
ServiceMaster's ability to exercise any of the rights granted by this Agreement
or the value of any such exercise.

     3.   Authorization to Execute Ballot. The Stockholder hereby irrevocably
          -------------------------------
authorizes ServiceMaster to execute as attorney in fact for the Stockholder any
ballot or consent form ServiceMaster shall reasonably deem appropriate to
accomplish the votes and consents required by this Agreement.

     4.   Transfer Restrictions.

          (a)  Until and unless the Merger Agreement has been terminated
(i) none of the Stockholder's LandCare Shares shall be tendered in response to
any tender offer, (ii) no interest in any of the Stockholder's LandCare Shares
shall be sold or otherwise transferred, (iii) the Stockholder will not take any
other action which would impair Stockholder's ability to vote any of
Stockholder's LandCare Shares in the manner required by this Agreement and (iv)
subject to Section 11 hereof, the Stockholder's commitments in Sections 1 though
3 shall be irrevocable.

          (b)  The Stockholder hereby agrees that for the period ending on the

Stockholder shall not sell, offer to sell, or otherwise transfer or dispose of
any ServiceMaster shares received in the Merger in exchange for the
Stockholder's LandCare Shares (the "Stockholder's ServiceMaster Shares"), engage
in put, call, short-sale, straddle or similar transactions involving
ServiceMaster Shares, or in any other way reduce the Stockholder's risk of
owning Stockholder's ServiceMaster Shares, provided that this restriction shall
not prohibit the Stockholder from pledging Stockholder's ServiceMaster Shares to
secure full-recourse indebtedness. ServiceMaster shall be entitled to place a
legend on the certificates representing the Stockholder's ServiceMaster Shares
identifying the restrictions imposed by this paragraph.

          (c)  The Stockholder hereby agrees that Stockholder's LandCare Shares
shall be legended to reflect the restrictions set forth herein in form
reasonably satisfactory to ServiceMaster. Upon execution of this Agreement, the
Stockholder shall deliver its LandCare Shares to LandCare for placement of the
restrictive legend and the shares shall be promptly returned to the Stockholder
thereafter.

     5.   Representations and Warranties of the Stockholder.
          -------------------------------------------------

          (a)  The Stockholder hereby warrants to ServiceMaster that the
Stockholder has the capacity to enter into this Agreement and the right and
power to perform his obligations under this Agreement.

          (b)  The Stockholder is not subject to or obligated under any
provision of (i) its organizational documents (if the Stockholder is not a

order, judgment or decree which would be breached or violated by the execution,
delivery and performance of this Agreement by the Stockholder.

          (c)  No authorization, consent or approval of, or any filing with, any
public body, court or authority is necessary for consummation by the Stockholder
of the transactions contemplated by this Agreement.

          (d)  The Stockholder's LandCare Shares listed adjacent to the
Stockholder's signature to this Agreement constitute all of LandCare Common
Stock over which the Stockholder possesses beneficial ownership or voting power
on the date of this Agreement. The Stockholder has absolute ownership of the
Stockholder's LandCare Shares free of any adverse interest and has 

                                       3
<PAGE>
 
necessary and sufficient night and authority to make the commitments with
respect to the Stockholder's LandCare Shares contained in this Agreement.

          (e)  The Stockholder is an accredited investor as defined in the Rule

Agreement. The Stockholder understands that ServiceMaster and LandCare are each
willing to respond to any questions or supply any information the Stockholder
shall desire in order to assess the risks and benefits of the transactions
contemplated by this Agreement and hereby confirms that there are no questions
that the Stockholder desires to ask or information the Stockholder desires to
obtain that has not been answered or supplied prior to the Stockholder's
execution of this Agreement.

     6.   Indemnification Currency. The Stockholder acknowledges that the
          ------------------------

previously acquired by LandCare and that LandCare issued the Stockholder's
LandCare Shares in connection with LandCare's acquisition of that business. The
agreement pursuant to which that acquisition occurred (the "Prior Acquisition
Agreement") provides that the Stockholder has the right to deliver LandCare
shares in satisfaction for certain indemnification obligations of the
Stockholder that may arise under that Agreement. ServiceMaster hereby agrees
that after the Merger, the Stockholder may use ServiceMaster shares to satisfy
any indemnification obligations that the Stockholder may have under the Prior
Acquisition Agreement to the same extent that the Stockholder was permitted to
use LandCare shares prior to the Merger. The Stockholder hereby agrees that the
Merger shall not limit or impair any indemnification obligation that the
Stockholder may have under the Prior Acquisition Agreement and hereby agrees
that the provisions in the Prior Acquisition Agreement that permit the
Stockholder to utilize LandCare shares to satisfy any certain indemnification
obligations that may arise under the Prior Acquisition Agreement shall be deemed
after the Merger to refer to ServiceMaster shares.

     7.   Further Assurances. The Stockholder will, upon the request of
          ------------------
ServiceMaster, execute and deliver such documents and take such action

                               VOTING AGREEMENT

         This Voting Agreement (this "Agreement") has been made as of November
1, 1998 (the "date hereof") by The ServiceMaster Company ("ServiceMaster") and
other party who has executed this Agreement (herein called the "Stockholder").

                                   RECITALS

         A. Concurrently with the execution and delivery of this Agreement,
ServiceMaster, SVM Acquisition Corporation, a wholly-owned subsidiary of
ServiceMaster ("Merger Subsidiary"), and LandCare USA, Inc. ("LandCare") are
entering into a Plan of Reorganization and Agreement and Plan of Merger of even
date herewith (which as constituted from time to time is herein called the
"Merger Agreement") which provides, among other things, that Merger Subsidiary
be merged into LandCare and that upon such Merger, LandCare will become a
wholly-owned subsidiary of ServiceMaster. The Merger Agreement also provides
that upon consummation of the Merger, each share of LandCare's Common Stock
outstanding immediately prior to consummation of the Merger will be converted
into a fraction of a share of Common Stock issuable by ServiceMaster. The term
"Merger" whenever it is used in this Agreement means the merger of the Merger
Subsidiary into LandCare.

         B. The Stockholder is the record and beneficial owner of the number of
shares of LandCare common stock set forth adjacent to the Stockholder's
signature to this Agreement. The term "Stockholder's LandCare Shares" means the
shares of Common Stock listed adjacent to the Stockholder's signature and any
other LandCare shares the Stockholder may acquire after the date hereof.

         C. The Stockholder has entered into this Agreement to induce
ServiceMaster to enter into the Merger Agreement.


THE PARTIES AGREE AS FOLLOWS:

         1. Agreement to Vote Shares.
            -------------------------

            (a) The Stockholder confirms that the Stockholder desires that
the Merger occur and has concluded that it is in the best interests of LandCare
and such Stockholder that LandCare's Board approve the Merger Agreement and that
LandCare sign the Merger Agreement and that it is better for LandCare to make
the commitments required by the Merger Agreement than to take the risk that by
seeking a higher offer for LandCare, the opportunity for acquisition by
ServiceMaster may be lost.

            (b) At every meeting of the Stockholders of LandCare called
with respect to any of the following, and at every adjournment thereof, and on
every action or approval by written consent of the Stockholders of LandCare with
respect to any of the following, the Stockholder irrevocably agrees to vote the
Stockholder's LandCare Shares: (i) in favor of the adoption of the 

                                       1
<PAGE>
 
Merger Agreement and approval of the Merger and any matter that could reasonably
be expected to facilitate consummation of the Merger (the "Merger Proposal");
and (ii) against approval of any proposal made in opposition to or competition
with consummation of the Merger and against any merger, consolidation, sale of
assets, reorganization or recapitalization with any party other than with
ServiceMaster and its affiliates and against any reorganization,
recapitalization, liquidation or winding up of LandCare (each of the things
cited in this clause (ii) is hereinafter referred to as an "Opposing Proposal").

            (c) The voting commitments in this Section 1 and in Section 2 and
the authorization in Section 3 shall end when and if (but not before) the Merger
Agreement shall be terminated in accordance with its terms.

     2.     No Support for Opposing Proposals.
            ---------------------------------
 
            (a) The Stockholder shall not 'invite or seek any Opposing
Proposal, support (or suggest that anyone else should support) any Opposing
Proposal that may be made, or ask LandCare's Board to consider, support or seek
any Opposing Proposal, or otherwise take any action designed to make any
Opposing Proposal more likely.

            (b) The Stockholder shall not meet or otherwise communicate
with any person that makes or is considering making an Opposing Proposal or any
representative of a person after becoming aware that the person has made or is
considering making a Opposing Proposal. The Stockholder shall promptly advise
ServiceMaster of each contact the Stockholder or any of the Stockholder's
representatives may receive from any person relating to any Opposing Proposal or
otherwise indicating that any person may wish to precipitate or engage in any
transaction arising out of any Opposing Proposal and will provide ServiceMaster
with all information ServiceMaster requests available to the Stockholder
regarding any Opposing Proposal or possible Opposing Proposal.

            (c) The Stockholder will not make any claim or join in any
litigation alleging that LandCare's Board is required to consider, endorse or
support any Opposing Proposal or to invite or seek any Opposing Proposal.

            (d) The Stockholder shall not take any other action that is
reasonably likely to make consummation of the Merger less likely or to impair
ServiceMaster's ability to exercise any of the rights granted by this Agreement
or the value of any such exercise.

         3. Authorization to Execute Ballot. The Stockholder hereby irrevocably
            -------------------------------   
authorizes ServiceMaster to execute as attorney in fact for the Stockholder any

         4.  Transfer Restrictions.
             ---------------------  

             (a) Until and unless the Merger Agreement has been terminated
(i) none of the Stockholder's LandCare Shares shall be tendered in response to
any tender offer, (ii) no interest in any of the Stockholder's LandCare Shares
shall be sold or otherwise transferred, (iii) the Stockholder will not take any
other action which would impair Stockholder's ability to vote any of
Stockholder's LandCare Shares in the manner required by this Agreement and (iv)
subject to Section 11 hereof, the Stockholder's commitments in Sections 1 though
3 shall be irrevocable.

             (b) The Stockholder hereby agrees that for the period ending on the
first anniversary of the issuance of the Stockholder's LandCare Shares the
Stockholder shall not sell, offer to sell, or otherwise transfer or dispose of
any ServiceMaster shares received in the Merger in exchange for the
Stockholder's LandCare Shares (the "Stockholder's ServiceMaster Shares"), engage
in put, call, short-sale, straddle or similar transactions involving
ServiceMaster Shares, or in any other way reduce the Stockholder's risk of
owning Stockholder's ServiceMaster Shares, provided that this restriction shall
not prohibit the Stockholder from pledging Stockholder's ServiceMaster Shares to
secure full-recourse indebtedness. ServiceMaster shall be entitled to place a
legend on the certificates representing the Stockholder's ServiceMaster Shares
identifying the restrictions imposed by this paragraph.

             (c) The Stockholder hereby agrees that Stockholder's LandCare
Shares shall be legended to reflect the restrictions set forth herein in form
reasonably satisfactory to ServiceMaster. Upon execution of this Agreement, the
Stockholder shall deliver its LandCare Shares to LandCare for placement of the
restrictive legend and the shares shall be promptly returned to the Stockholder
thereafter.

         5.  Representations and Warranties of the Stockholder.
             ------------------------------------------------- 

             (a) The Stockholder hereby warrants to ServiceMaster that the
Stockholder has the capacity to enter into this Agreement and the right and
power to perform his obligations under this Agreement.

             (b) The Stockholder is not subject to or obligated under any
provision of (i) its organizational documents (if the Stockholder is not a

order, judgment or decree which would be breached or violated by the execution,
delivery and performance of this Agreement by the Stockholder.

             (c) No authorization, consent or approval of, or any filing with,
any public body, court or authority is necessary for consummation by the
Stockholder of the transactions contemplated by this Agreement.

             (d) The Stockholder's LandCare Shares listed adjacent to the
Stockholder's signature to this Agreement constitute all of LandCare Common
Stock over which the Stockholder possesses beneficial ownership or voting power
on the date of this Agreement. The Stockholder has absolute ownership of the
Stockholder's LandCare Shares free of any adverse interest and has

                                       3

LandCare are each willing to respond to any questions or supply any
information the Stockholder shall desire in order to assess the risks and
benefits of the transactions contemplated by this Agreement and hereby confirms

agreement pursuant to which that acquisition occurred (the "Prior Acquisition
Agreement" provides that the Stockholder has the right to deliver LandCare
shares in satisfaction for certain indemnification obligations of the
Stockholder that may arise under that Agreement. ServiceMaster hereby agrees
that after the Merger, the Stockholder may use ServiceMaster shares to satisfy
any indemnification obligations that the Stockholder may have under the Prior
Acquisition Agreement to the same extent that the Stockholder was permitted to
use LandCare shares prior to the Merger. The Stockholder hereby agrees that the
Merger shall not limit or impair any indemnification obligation that the
Stockholder may have under the Prior Acquisition Agreement and hereby agrees
that the provisions in the Prior Acquisition Agreement that permit the
Stockholder to utilize LandCare shares to satisfy any certain indemnification
obligations that may arise under the Prior Acquisition Agreement shall be deemed
after the Merger to refer to ServiceMaster shares.

         7.  Further Assurances. The Stockholder will, upon the request of

action or approval by written consent of the Stockholders of LandCare with

EXHIBIT 13


                               VOTING AGREEMENT

         This Voting Agreement (this "Agreement") has been made as of November
1, 1998 (the "date hereof") by The ServiceMaster Company ("ServiceMaster") and
other party who has executed this Agreement (herein called the "Stockholder").

                                   RECITALS

         A.       Concurrently with the execution and delivery of this
Agreement, ServiceMaster, SVM Acquisition Corporation, a wholly-owned subsidiary
of ServiceMaster ("Merger Subsidiary"), and LandCare USA, Inc. ("LandCare") are
entering into a Plan of Reorganization and Agreement and Plan of Merger of even
date herewith (which as constituted from time to time is herein called the
"Merger Agreement") which provides, among other things, that Merger Subsidiary
be merged into LandCare and that upon such Merger, LandCare will become a 
wholly-owned subsidiary of ServiceMaster. The Merger Agreement also provides
that upon consummation of the Merger, each share of LandCare's Common Stock
outstanding immediately prior to consummation of the Merger will be converted
into a fraction of a share of Common Stock issuable by ServiceMaster. The term
"Merger" whenever it is used in this Agreement means the merger of the Merger
Subsidiary into LandCare.

         B.       The Stockholder is the record and beneficial owner of the
number of shares of LandCare common stock set forth adjacent to the
Stockholder's signature to this Agreement. The term "Stockholder's LandCare
Shares" means the shares of Common Stock listed adjacent to the Stockholder's
signature and any other LandCare shares the Stockholder may acquire after the
date hereof.

         C.       The Stockholder has entered into this Agreement to induce
ServiceMaster to enter into the Merger Agreement.


THE PARTIES AGREE AS FOLLOWS:

         1.       Agreement to Vote Shares.
                  ------------------------

the Merger occur and has concluded that it is in the best interests of LandCare
and such Stockholder that LandCare's Board approve the Merger Agreement and that
LandCare sign the Merger Agreement and that it is better for LandCare to make
the commitments required by the Merger Agreement than to take the risk that by
seeking a higher offer for LandCare, the opportunity for acquisition by
ServiceMaster maybe lost.

                  (b) At every meeting of the Stockholders of LandCare called
with respect to any of the following, and at every adjournment thereof, and on
every action or approval by written consent of the Stockholders of LandCare with
respect to any of the following, the Stockholder irrevocably agrees to vote the
Stockholder's LandCare Shares: (i) in favor of the adoption of the

be expected to facilitate consummation of the Merger (the "Merger Proposal"),
and (ii) against approval of any proposal made in opposition to or competition
with consummation of the Merger and against any merger, consolidation, sale of
assets, reorganization or recapitalization with any party other than with
ServiceMaster and its affiliates and against any reorganization,

cited in this clause (ii) is hereinafter referred to as an "Opposing Proposal").

                  (c) The voting commitments in this Section 1 and in Section 2

any Opposing Proposal, or otherwise take any action designed to make any
Opposing Proposal more likely.

                  (b) The Stockholder shall not meet or otherwise communicate
with any person that makes or is considering making an Opposing Proposal or any
representative of a person after becoming aware that the person has made or is
considering making a Opposing Proposal. The Stockholder shall promptly advise
ServiceMaster of each contact the Stockholder or any of the Stockholder's
representatives may receive from any person relating to any Opposing Proposal or
otherwise indicating that any person may wish to precipitate or engage in any

with all information ServiceMaster requests available to the Stockholder
regarding any Opposing Proposal or possible Opposing Proposal.

litigation alleging that LandCare's Board is required to consider, endorse or
support any Opposing Proposal or to invite or seek any Opposing Proposal.

                  (d) The Stockholder shall not take any other action that is
reasonably likely to make consummation of the Merger less likely or to impair
ServiceMaster's ability to exercise any of the rights granted by this Agreement
or the value of any such exercise.

         3.       Authorization to Execute Ballot. The Stockholder hereby
                  -------------------------------
irrevocably authorizes ServiceMaster to execute as attorney in fact for the

EXHIBIT 14


                               VOTING AGREEMENT

     This Voting Agreement (this "Agreement") has been made as of November 1,
1998 (the "date hereof") by The ServiceMaster Company ("ServiceMaster") and
other parties who have executed this Agreement (herein called the
"Stockholders").

                                   RECITALS

     A.   Concurrently with the execution and delivery of this Agreement,
ServiceMaster, SVM Acquisition Corporation, a wholly-owned subsidiary of
ServiceMaster ("Merger Subsidiary"), and LandCare USA, Inc. ("LandCare") are
entering into a Plan of Reorganization and Agreement and Plan of Merger of even
date herewith (which as constituted from time to time is herein called the
"Merger Agreement") which provides, among other things, that Merger Subsidiary
be merged into LandCare and that upon such Merger, LandCare will become a
wholly-owned subsidiary of ServiceMaster. The Merger Agreement also provides
that upon consummation of the Merger, each share of LandCare's Common Stock
outstanding immediately prior to consummation of the Merger will be converted
into a fraction of a share of Common Stock issuable by ServiceMaster. The term
"Merger" whenever it is used in this Agreement means the merger of the Merger
Subsidiary into LandCare.

     B.   The Stockholders are the record and beneficial owners of the number
of shares of LandCare common stock set forth adjacent to the Stockholders'
signatures to this Agreement. The term "Stockholders' LandCare Shares" means the
shares of Common Stock listed adjacent to the Stockholders' signatures and any
other LandCare shares the Stockholders may acquire after the date hereof.

     C.   The Stockholders have entered into this Agreement to induce
ServiceMaster to enter into the Merger Agreement.

THE PARTIES AGREE AS FOLLOWS:

     1.   Agreement to Vote Shares.
          ------------------------

          (a)  The Stockholders confirm that the Stockholders desire that
the Merger occur and have concluded that it is in the best interests of LandCare
and such Stockholders that LandCare's Board approve the Merger Agreement and
that LandCare sign the Merger Agreement and that it is better for LandCare to
make the commitments required by the Merger Agreement than to take the risk that
by seeking a higher offer for LandCare, the opportunity for acquisition by
ServiceMaster may be lost.

          (b)  At every meeting of the stockholders of LandCare called
with respect to any of the following, and at every adjournment thereof, and on
every action or approval by written consent of the stockholders of LandCare with
respect to any of the following, the Stockholders irrevocably agree to vote the
Stockholders' LandCare Shares: (i) in favor of the adoption of the 

                                       1
<PAGE>
 
Merger Agreement and approval of the Merger and any matter that could reasonably
be expected to facilitate consummation of the Merger (the "Merger Proposal");
and (ii) against approval of any proposal made in opposition to or competition
with consummation of the Merger and against any merger, consolidation, sale of
assets, reorganization or recapitalization, with any party other than with
ServiceMaster and its affiliates and against any reorganization,
recapitalization, liquidation or winding up of LandCare (each of the things
cited in this clause (ii) is hereinafter referred to as an "Opposing Proposal").

          (c)  The voting commitments in this Section 1 and in Section 2
and the authorization in Section 3 shall end when and if (but not before) the
Merger Agreement shall be terminated in accordance with its terms.

          ---------------------------------

          (a)  The Stockholders shall not invite or seek any Opposing Proposal,

Proposal, or otherwise take any action designed to make any Opposing Proposal
more likely.

          (b)  The Stockholders shall not meet or otherwise communicate with any
person that makes or is considering making an Opposing Proposal or any
representative of a person after becoming aware that the person has made or is

ServiceMaster of each contact the Stockholders or any of the Stockholders'
representatives may receive from any person relating to any Opposing Proposal or
otherwise indicating that any person may wish to precipitate or engage in any
transaction arising out of any Opposing Proposal and will provide ServiceMaster
with all information ServiceMaster requests available to the Stockholders
regarding any Opposing Proposal or possible Opposing Proposal.

          (c)  The Stockholders will not make any claim or join in any
litigation alleging that LandCare's Board is required to consider, endorse or
Support any Opposing Proposal or to invite or seek any Opposing Proposal.

          (d)  The Stockholders shall not take any other action that is
reasonably likely to make consummation of the Merger less likely or to impair
ServiceMaster's ability to exercise any of the rights granted by this Agreement
or the value of any such exercise.

     3.   Authorization to Execute Ballot. The Stockholders hereby irrevocably
          -------------------------------

3 shall be irrevocable.

          (b)  The Stockholders hereby agree that for the period ending

of any ServiceMaster shares received in the Merger in exchange for the
Stockholders' LandCare Shares (the "Stockholders' ServiceMaster Shares"), engage
in put, call, short-sale, straddle or similar transactions involving
ServiceMaster Shares, or in any other way reduce the Stockholders' risk of
owning Stockholders' ServiceMaster Shares, provided that this restriction shall
not prohibit the Stockholders from pledging Stockholders' ServiceMaster Shares
to secure full-recourse indebtedness. ServiceMaster shall be entitled to place a
legend on the certificates representing the Stockholders' ServiceMaster Shares
identifying the restrictions imposed by this paragraph.

          (c)  The Stockholders hereby agree that Stockholders' LandCare
Shares shall be legended to reflect the restrictions set forth herein in form
