Executive.

     2.  TERM.  Subject only to the provisions hereof set forth in Section 7,
the term of this Agreement (herein the "Term") shall be for a period beginning

Agreement shall be renewed for a period ending on the earlier of (i) the date
two (2) 

 
years from such March 10, or (ii) the date of the Executive's 62nd
birthday on which birthday this Agreement shall terminate unless earlier

     3.  COMPENSATION.  During the Term, the Executive's salary shall be payable

initially be $350,000 per annum and thereafter be established by either the
Compensation and Stock Option Committee of the Board of Directors of the Company
(subject to approval by the full Board) or, in the event Executive is not among
the Company officers whose compensation is subject to review by the Compensation
and Stock Option Committee of the Board, by the Executive Committee of the
Company (the applicable committee being referred to herein as the "Committee")
and all adjustments thereto and all aspects of the Executive's incentive or
performance compensation shall be established by the Committee in its sole
discretion.  In the event there is no Committee in existence at any time, the

executives of the Employer including, without limitation, incentive
compensation, loans, awards, insurance, stock options, stock purchase plans,
benefits from qualified plans or non-qualified plans or other benefit plans now
or hereafter existing which are adopted by the Employer for the benefit of its

Benefits to be provided in such amounts as may be determined from time to time
by the Committee in its discretion.

     4.  EXTENT OF SERVICE.  During the Term, the Executive shall devote his
full time, attention and energy to the business of the Employer and the
Executive shall not be engaged in any other business activity pursued for gain,
profit or other pecuniary advantage which activity interferes with the
Executive's duties and responsibilities provided for herein.

     5.   NON-COMPETITION AND NON-SOLICITATION.  Executive agrees that:
          ------------------------------------                          

          (a) During the Term and for a period of one year thereafter or during
any Severance Period, if longer (the "Restricted Period"), Executive agrees that
he will not (without the written consent of the Chief Executive Officer) engage
directly or indirectly in any business within the United States (financially as
an investor or lender or as an employee, director, officer, partner, independent
contractor, consultant or owner or in any other capacity calling for the
rendition of personal services or acts of management, operation or control)
which is directly competitive with the business at any time during the Term
conducted by the Company or any of its subsidiaries or Affiliates as defined
below.  Notwithstanding the foregoing, Executive shall be entitled to own
securities of any corporation conducting a business competitive with the
business of the Company or any of its subsidiaries or Affiliates so long as the
securities of such corporation are listed on a national securities exchange and
the securities owned directly or indirectly by Executive do not represent more
than two percent (2%) of any class of the outstanding securities of such
company.

          (b) During the Restricted Period, in addition to the obligations
pursuant to Subsection 5(a), Executive agrees that neither he nor any business
in which he engages directly or 

                                       2

 
indirectly will (i) directly or indirectly induce any customers of the Company
or of corporations or businesses which directly or indirectly control or are
controlled by or under common control with the Company ("Affiliates") to
patronize any business similar to that of the Company, (ii) canvass, solicit or
accept any similar business from any customer of the Company or any Affiliates,
(iii) directly or indirectly request or advise any customer of the Company or
Affiliates to withdraw, curtail or cancel such customer's business with the
Company or Affiliates, (iv) directly or indirectly disclose to any other person,
firm or corporation the names or addresses of any of the customers of the
Company or Affiliates, or (v) compete with the Company or Affiliates in
acquiring or merging with any other business or acquiring the assets of such
other business.

          (c) During the Restricted Period, in addition to the obligations
pursuant to Subsections 5(a) and 5(b), Executive agrees that neither he nor any
business in which he engages directly or indirectly will (i) hire or attempt to
hire any employee of the Company or its Affiliates nor (ii) directly or
indirectly encourage any employee of the Company or its Affiliates to terminate
employment with the Company or its Affiliates.  Notwithstanding the foregoing,
it shall not be deemed a violation of this subsection if a business which
employs Executive hires or attempts to hire an employee of the Affiliates and
Executive has no knowledge of, control over or involvement with such
solicitation.

          (d) In the event that any of the provisions of this Section 5 should
ever be deemed to exceed the time, geographic or occupational limitations
permitted by applicable laws, then such provisions shall be and are hereby
reformed to the maximum time, geographic or occupational limitations permitted
by law.

      6.  CONFIDENTIAL INFORMATION.  The Executive acknowledges that in his
employment he is or will be making use of, acquiring or adding to the Employer's
and Company's confidential information which includes, but is not limited to,
memoranda and other materials or records of a proprietary nature and records and
policy matters relating to finance, personnel, management and operations.
Therefore, in order to protect the Employer's and Company's confidential
information and to protect other employees who depend on the Employer and
Company for regular employment, the Executive agrees that he will not in any way
utilize any of said confidential information except in connection with his
employment by the Employer, and except in connection with the business of the
Employer and Company he will not copy, reproduce or take with him the original
or any copies of said confidential information and will not disclose any of said
confidential information to anyone.

      7.  TERMINATION.
          ----------- 

          (a) Death or Disability. If the Executive should become physically
or mentally disabled and unable to perform his duties hereunder for a continuous
period in excess of ninety (90) days (in the reasonable opinion of the
Committee), or if the Executive should die while an employee of the Employer,
this Agreement and Executive's employment with the Employer shall immediately
terminate.

                                       3

 
          (b) Termination by the Employer for Cause.  The following events shall
create in the Employer a right to terminate the Executive's employment under
this Agreement prior to the expiration of the Term: (i) the commission of fraud,
embezzlement or theft by the Executive in connection with the Executive's
duties; (ii) the intentional wrongful damage to property of the Company, the
Employer and/or their Affiliates by the Executive; (iii) the intentional
wrongful disclosure by the Executive of any secret process or confidential
information of the Company, the Employer and/or their Affiliates; or (iv) the
violation of the Executive's non-disclosure, non-solicitation and non-
competition covenants set forth in Sections 5 and 6.  In the event of such a
Termination for cause pursuant to this Subsection, all of the obligations of the
Employer and the Company under this Agreement shall immediately terminate.

          (c) Other Termination by Employer. In the event the Employer shall
elect to terminate Executive's employment for any reason other than those
specified in Subsection 7(a) or 7(b), it shall provide written notice of such
termination to Executive. In the event that there occurs without the written
consent of the Executive:

          (i)    a change in the Executive's duties, title or responsibilities,
                 or a change in the Executive's reporting relationships, either
                 of which results in or reflects a diminution of the scope or
                 importance of the Executive's duties and responsibilities;

          (ii)   a reduction in the Executive's then current annual base salary
                 (other than as part of reductions in annual base salary
                 affecting the Employer's officers generally);

          (iii)  a reduction in the level of benefits available or awarded under
                 employee and officer benefit plans and programs, including, but
                 not limited to annual and long-term incentive and stock-based
                 plans and programs (other than as part of reductions in such
                 benefit plans or programs affecting the Employer's officers
                 generally);

          (iv)   a relocation of Executive's primary employment location to a
                 location which is more than 50 miles from his current location;
                 or

          (v)    the Company terminates the automatic renewal provision of this
                 Agreement by providing Executive with 30 days' prior written
                 notice as provided in Section 2 hereof

     then Executive may deliver written notice of termination of his employment
     to the Company within three months of such event (which notice shall be
     effective even if such three months expire after the end of the Term). In
     the event of notice being given by the Employer or Executive under this
     Subsection 7(c) within one year of Executive's initial employment with the
     Employer, and subject to the execution and delivery by Executive to the
     Company of the release described in Section 10 hereof, the Company shall
     provide 

                                       4

 
     Executive with the severance compensation and benefits set forth in
     (u), (w), (x), (y), and (z) below.  In the event of notice being given by
     the Employer or Executive under this Subsection 7(c) after one year of
     Executive's initial employment with the Employer, subject to the execution
     and delivery by Executive to the Company of the release described in
     Section 10 hereof, the Company shall provide Executive with severance
     compensation and benefits set forth in (u)-(z) below:
     
          (u) Executive shall receive an amount equal to his then current base
          salary for two years, payable at intervals not less frequently than
          monthly over a period of two years following the end of the Term (such
          period of payment to be referred to herein as the "Severance Period");

          (v) with respect to any participation rights in the Company's annual
          or long-term incentive plans which have been awarded to Executive
          prior to the end of the Term, Executive shall be entitled to receive a
          prorated award under any such plan, payable if and when awards are
          paid to other similarly positioned officers of the Employer, such
          proration to be determined by dividing the number of whole or partial
          months the Executive is employed during the incentive compensation
          performance period by the total number of months in the incentive
          compensation performance period;

          (w) with respect to Executive's stock options, the exercisability of
          Executive's outstanding stock options shall be accelerated, and such
          options shall remain exercisable during the Severance Period (unless
          they shall otherwise expire earlier by their terms) and such options
          shall otherwise be treated in accordance with the terms of their
          respective grants;

          (x) the Executive's medical, dental and vision Benefits shall be
          continued on the same basis as offered to active salaried employees
          for the Severance Period or until such earlier time as the Executive
          becomes employed and eligible for such benefits under a plan of the
          new employer, and continuation coverage under COBRA shall commence at
          the end of the Severance Period; and

          (y) credit for vesting and benefit service under the Company's
          Supplemental Executive Retirement Plan shall be provided to Executive
          for the Severance Period; and

          (z) all other Benefits shall be paid or continued only to the extent
          the terms thereof provide for payment or continuation following the
          termination of employment.

                                       5

 
The foregoing shall be in lieu of all salary, bonuses or incentive or
performance based compensation for the remainder of the Term.  If Executive
should die during the Severance Period, any remaining severance payments shall
be made to Executive's surviving spouse or, if none, to his estate.

     (d) Voluntary Termination. If during the Term the Executive should
voluntarily terminate his employment with the Employer for any reason, including
retirement, other than as described in Subsection 7(c) hereof, the obligations
of the Employer and the Company under this Agreement shall terminate forthwith,
other than obligations to (i) pay the Executive's base salary to the date of
voluntary termination, (ii) pay all incentive compensation earned by the
Executive for performance periods which are completed prior to the date of
voluntary termination, at such times and on the same basis amounts as such
incentive compensation becomes payable to other executives of the Employer and
(iii) pay or make available to the Executive all Benefits which by their terms
or under applicable law survive the voluntary termination of the Executive's
employment; and the Executive shall remain bound by his non-disclosure, non-
solicitation and non-competition covenants set forth in Sections 5 and 6 hereof.
The exercisability of the Executive's outstanding stock options shall be treated
in accordance with the terms of their respective grants or awards, except that
in the case of retirement on or after age 62, the Company will recommend to the
Compensation and Stock Option Committee of the Board of Directors of the Company
that the exercisability of Executive's outstanding stock options be accelerated.

     8.  ELECTION TO EXTEND SEVERANCE PERIOD.  Notwithstanding anything in
Subsection 7(c) to the contrary, the Executive may make an irrevocable written
election, within 30 days of receipt or delivery of the written termination
notice provided for in Subsection 7(c), that would extend the time period during
which the base salary is to be paid under Subsection 7(c) for one additional
year.  The total amount of base salary that is to be paid under Subsection 7(c)
will not be affected by this election.  If such election is made, the term
"Severance Period" will be deemed to refer to such extended payment period.

     9.  EXCISE TAX.  In the event that an excise tax ("Excise Tax") is imposed 
on Executive under Section 4999 of the Internal Revenue Code (or any successor
provision of like import) on the payments due under Subsection 7(c)
(collectively, the "Payments"), Executive shall be paid an additional amount
("Gross Up") no later than 30 days prior to the date such Excise Tax is due,
such that the net amount retained by Executive after deduction of the Excise Tax
on the Payments and any federal and state income taxes on the Payments and the
Gross Up shall be equal to the Payments. For purposes of determining the Gross
Up, Executive shall be deemed to pay federal and state income taxes at the
highest marginal rate of taxation in the calendar year in which the Payments or
Gross Up is to be made. The opinion of whether such Excise Tax is payable and
the amount thereof shall be based upon a "substantial authority opinion" of tax
counsel selected by the Company and reasonably acceptable to Executive. If such
opinion is not finally accepted by the IRS upon audit, then appropriate
adjustments shall be computed (with Gross Up) by tax counsel based upon the
final amount of Excise Tax so

                                       6

 
determined.  The amount shall be paid by the appropriate party in one lump cash
sum within 30 days of such computation.

     10.  GENERAL RELEASE AND COOPERATION AGREEMENT. Notwithstanding anything in
Subsection 7(c) or Section 9 to the contrary and in consideration therefor,
severance benefits and the Gross Up thereunder shall only become payable by the
Company if the Executive executes and delivers to the Company a General Release
and Cooperation Agreement on or after the date of written notice of termination
of Executive's employment or prior to the date the Gross Up is paid, as
applicable, and in substantially the form attached as Exhibit A hereto.

     11.  NOTICES.  Any notice required or permitted to be given under this
Agreement shall be in writing and shall be deemed to have been given when
deposited in the U.S. mail in a registered, postage prepaid envelope addressed:

Executive may direct, and if to the Company, c/o Chief Executive Officer, Waste
Management, Inc., 3003 Butterfield Road, Oak Brook, Illinois 60523, with a copy
to the General Counsel, Waste Management, Inc., at the same address.

     12.  ASSIGNMENT. The Executive may not assign his obligations hereunder.
The rights of the Executive and the rights and obligations of the Company
hereunder shall inure to the benefit of and shall be binding upon their
respective heirs, personal representatives, successors and assigns.
 
     13.  MISCELLANEOUS.
          ------------- 
 
          (a) This Agreement shall be subject to and governed by the laws of the
State of Illinois.

          (b) Failure to insist upon strict compliance with any provisions
hereof shall not be deemed a waiver of such provisions or any other provision
hereof.

          (c) This Agreement may not be modified except by an agreement in
writing executed by the parties hereto.

          (d) The invalidity or unenforceability of any provision hereof shall
not affect the validity or enforceability of any other provision.

          (e) This Agreement shall supersede any and all prior employment
agreements or understandings, written or oral, with Executive.
