effective April 1, 2001.

Plan shall be interpreted and administered consistent with this intent.

         (a) An Employee whose stated Base Salary and target Bonus as of the
first day of a Plan Year exceeds the annual compensation limit established under
Code Section 401(a)(17) for such Plan Year shall be eligible to participate in
the Plan for such Plan Year. For any Plan Year beginning on or after January 1,

if his or her stated Base Salary for the year before the Plan Year equals or
exceeds




                                       3
<PAGE>

$170,000, or if the Employee is hired during the Plan Year, his or her stated
Base Salary on the Employee's date of hire equals or exceeds $170,000.

         (b) Prior to each Plan Year, the Plan Administrator shall determine the
identity of those Employees who are eligible to commence their participation in
the Plan pursuant to Section 3.1(a) and those Participants who may continue
their participation in the Plan for such Plan Year pursuant to Section 3.1(a).
The Plan Administrator will notify those Employees of their eligibility to
participate (or continue participation) in the Plan and provide them with a
Deferral Form. The Plan Administrator shall have the sole discretion to
determine eligibility pursuant to the Plan.

         3.2 PARTICIPATION. An Eligible Employee who properly completes a
Deferral Form shall become a Participant in the Plan on the first date as of
which an Elective Deferral or Bonus Deferral is credited to his or her Account.
A Participant in the Plan shall continue to be a Participant so long as any
amount remains credited to his or her Account.

         3.3 SUSPENSION OF PARTICIPATION. If the Plan Administrator determines
that a Participant currently making Elective Deferrals or receiving Matching
Allocations no longer satisfies the eligibility requirements of Section 3.1(a)
during the Plan Year, the Plan Administrator may suspend the Participant's
Elective Deferrals and Matching Allocations until the next following Plan Year
as of which the Participant again satisfies such eligibility requirements. In
such circumstance, the Plan Administrator shall notify the Participant of such
suspension. If the Participant's participation is suspended as described in this
Section 3.3 and the Plan Administrator determines that the Participant again
satisfies the eligibility requirements of Section 3.1(a), the Plan Administrator
shall notify the Participant, and the Participant shall be permitted to resume
active participation in the Plan as of the next following Plan Year.

                           DEFERRALS AND CONTRIBUTIONS

Employee may irrevocably elect to defer, on a pre-tax basis, up to 25% (in whole
percentages) of his or her Base Salary. Such an election is a separate and
independent election from an election to defer compensation under the Qualified
Plan.

         4.2 BONUS DEFERRALS. With respect to any Plan Year, an Eligible
Employee may irrevocably elect to defer all or a portion of his or her Bonus (in
whole percentages). Notwithstanding the foregoing, the amount of an Eligible
Employee's Bonus eligible for deferral in a given Plan Year shall not exceed the
Bonus reduced by sum of any before-tax contributions made to the Qualified Plan
and the amount necessary to satisfy the tax due for FICA with respect to such
Bonus.

         4.3 ELECTIONS.

         (a) TIME FOR MAKING DEFERRAL ELECTIONS.

                  (i)      ELECTIVE DEFERRALS.

<PAGE>

                           (A)      Generally. An election to defer Base Salary
                                    shall be made prior to the calendar year in
                                    which the Base Salary is earned; provided,
                                    that, for the Plan Year beginning on the
                                    Effective Date, such elections shall be made
                                    prior to April 1, 2001 and shall only be
                                    effective for Base Salary earned on and
                                    after such date. The Plan Administrator will
                                    notify each Eligible Employee of the
                                    applicable election period and deadline for
                                    filing such elections.

                           (B)      Newly Eligible Employees. In the case of an
                                    Eligible Employee in his or her first year
                                    of employment, an election to defer Base
                                    Salary must be made within 30 days after the
                                    Eligible Employee begins employment and at
                                    least five business days before the
                                    commencement of the first payroll period for
                                    which the election is effective. Such
                                    elections are effective only with respect to
                                    Base Salary earned after the effective date
                                    of the election.

                  (ii)     BONUS DEFERRALS. An election to defer Bonuses must be
                           made on or before December 31 of the Plan Year that
                           precedes the Plan Year in which the Bonus is
                           otherwise paid.

         (b) DEFERRAL FORMS; IRREVOCABILITY. All Deferral Forms for Elective and
Bonus Deferrals must be timely filed, recorded or otherwise made in the manner
prescribed by the Plan Administrator. An Eligible Employee may change a prior
election up to the date established under Section 4.3(i) or (ii), as applicable.
However, from and after the last date permitted for making such elections, all
deferral elections pursuant to this Article 4 shall be irrevocable.

         (c) NO ELECTION. A Deferral Form for a Plan Year shall not apply to
subsequent Plan Years. If no election to defer Base Salary or Bonuses is made
for a given Plan Year, no deferrals shall be made for such Plan Year.

         4.4 MATCHING ALLOCATIONS.

         (a) No later than the latest date permitted by Code Section 404 for
matching contributions under the Qualified Plan with respect to each Plan Year
thereunder (or such later date that the need for a matching contribution is
determined), the Employer shall credit a Matching Allocation to the Account of
each Participant who is an Eligible Employee and is entitled to such a
contribution pursuant to Section 4.4(b).

         (b) With respect to each payroll period after a Participant reaches the
Limit, such Participant shall receive a Matching Allocation equal to (i) 100% of
the Participant's Matched Deferrals up to 3% of the Participant's Total
Compensation, plus (ii) 50% of the Participant's Matched Deferrals in excess of
3% of the Participant's Total Compensation, up to 6% of the Participant's Total
Compensation. Notwithstanding the foregoing, the Committee, in its sole and
absolute discretion, may adjust a Participant's Matching Allocation to the
extent necessary to ensure that he or she does not receive matching
contributions under this Plan and the Qualified Plan that exceed the sum of (i)
100% of the Participant's deferrals under this Plan and elective contributions
under the Qualified Plan up to 3% of Total Compensation and (ii) 50% of the



                                       5
<PAGE>

Participant's deferrals under this Plan and elective contributions under the
Qualified Plan in excess of 3% of Total Compensation, up to 6% of Total
Compensation.

                                    ARTICLE 5
                                    ACCOUNTS

         5.1 ACCOUNTS. The Plan Administrator shall establish an Account for
each Participant to reflect Elective Deferrals, Bonus Deferrals, Matching
Allocations, if any, and Transferred Amounts made for the Participant's benefit
together with any adjustments for income, gain or loss and any payments from the
Account. A separate sub-account shall be established for Elective Deferrals,
Bonus Deferrals, if any, and Matching Allocations, if any. Elective Deferrals
shall be credited as of the end of each payroll period, and Bonus Deferrals
shall be credited as of the date on which the Bonus would otherwise be paid. The
Accounts are established solely for the purposes of tracking Elective Deferrals,
Bonus Deferrals, Matching Allocations and any income adjustments thereto. The
Accounts shall not be used to segregate assets for payment of any amounts
deferred or allocated under the Plan.

         5.2 INVESTMENTS.

         (a) Amounts credited to each Participant's Account shall be deemed
invested, in accordance with the Participant's directions, in one or more
investment funds that are available under the Plan. If a Participant does not
make investment elections with respect to amounts credited to his or her
Account, such amounts shall be deemed invested in the Moderate Asset Allocation
Fund or such other investment fund as the Investment Committee of the Waste
Management Employee Benefit Plans may direct.

         (b) A Participant shall make his or her investment fund selections at
such time as he or she files the Deferral Form, as described in Article 4.
Investments must be made in whole percentages. A Participant may change his or
her investment elections at any time, or may reallocate amounts invested among
the investment funds available under the Plan.

         (c) Expense charges for transactions performed for each Participant's
sub-account shall be debited against each respective sub-account and shall be
listed on the quarterly statement. Other Plan charges and administrative
expenses will be paid by the Employer without debit against Participant
Accounts.

         5.3 STATEMENTS. As soon as practicable following the last business day
of each calendar quarter, the Plan Administrator (or its designee) shall provide
the Participant with a statement of such Participant's Account reflecting the
deemed income, gains and losses (realized and unrealized), amounts of deferrals
and distributions with respect to such Account since the prior statement.

                                    ARTICLE 6
                                     VESTING

         Subject to the provisions of Sections 7.4, 7.5 and 8.1, a Participant
shall at all times have a fully vested and nonforfeitable right to all Elective
Deferrals, Bonus Deferrals, if any, and



                                       6

Matching Allocations, if any, credited to the Participant's Account, adjusted
for deemed income, gain and loss attributable thereto.

                                    ARTICLE 7
                            DISTRIBUTION OF ACCOUNTS

         7.1 ELECTION AS TO TIME AND FORM OF PAYMENT.

         (a) GENERAL PAYMENT OPTIONS. Except as otherwise permitted in this
Article 7, a Participant may elect, on a Payment Form, one of the following
payment options for all amounts credited to a Participant's Account:

                  (i)      a lump sum payment in February of the calendar year
                           following either (A) a future date or age that occurs
                           on or after termination of employment, or (B)
                           retirement at age 65; or

                  (ii)     annual installments over a period of up to ten years
                           (as elected by the Participant), to begin in February
                           of the calendar year following a specific date or
                           age.

         Any such election shall be made in accordance with procedures and rules
established by the Plan Administrator.

         If a Participant does not make an election, distribution shall be made
in a single lump sum in February of the calendar year following the
Participant's termination of employment. Payments from a Participant's Account
may be in cash or in property, as determined by the Plan Administrator or the
trustee of any existing trust from which payment is made.

         For purposes of the Plan, a Participant shall terminate employment when
the Participant separates from service with the Company and all majority-owned
subsidiaries of the Company. However, temporary absence from employment because
of illness, vacation, approved leaves of absences, and transfers of employment
among the Company and its majority-owned subsidiaries shall not be considered a
termination of employment or an interruption of employment.

         (b) SCOPE OF ELECTIONS. The elections under this Section 7 shall apply
to all amounts credited to a Participant's Account.

         (c) PERMITTED CHANGES. Subject to approval by the Plan Administrator, a
Participant may change the payment form or date elected for distribution of his
or her Account under Section 7.1(a) before any payment is made under his or her
existing election by properly completing a new Payment Form and filing such form
with the Plan Administrator at least 12 months before the first payment is due
under the new election. Such change shall apply to all amounts credited to the
Participant's Account.

         7.2 DEATH.

         (a) If a Participant dies before payment or complete distribution (in
the case of installment payouts) of his or her Account, all amounts credited to
the Participant's Account



                                       7
<PAGE>

shall be paid to the Participant's designated Beneficiary, according to the
Participant's distribution election, unless the Plan Administrator elects, in
its sole discretion, to pay out a Participant's Account balance in a single lump
sum as soon as practicable following the date of the Participant's death.

         (b) A Participant may designate a Beneficiary by notifying the Plan
Administrator in writing, at any time before Participant's death, on a form
prescribed by the Plan Administrator for that purpose. A Participant may revoke
any Beneficiary designation or designate a new Beneficiary at any time without
the consent of a Beneficiary or any other person. If no Beneficiary is
designated or no Beneficiary survives the Participant, payment shall be made to
the Participant's surviving spouse, or, if none, to the Participant's estate.

         7.3 UNFORESEEABLE EMERGENCY. If a Participant experiences an
unforeseeable emergency, the Plan Administrator, in its sole discretion, may pay
to the Participant only that portion, if any, of the Participant's Account that
the Plan Administrator determines is necessary to satisfy such emergency,
including any amounts necessary to pay any federal, state or local income taxes
reasonably anticipated to result from the distribution. A Participant requesting
a distribution due to an unforeseeable emergency shall apply for the
distribution in writing using a form prescribed by the Plan Administrator for
that purpose and shall provide such additional information as the Plan
Administrator may require. For purposes of the Plan, an "unforeseeable
emergency" is an unanticipated emergency that is caused by an event beyond the
control of the Participant or Beneficiary and that would result in severe
financial hardship to the Participant or Beneficiary if withdrawal is not
permitted. Unforeseeable emergencies may include:

         (a) Expenses that are not covered by insurance and that the Participant
or his or her spouse or dependent has incurred as a result of, or is required to
incur in order to receive medical care;

         (b) The need to prevent the eviction of the Participant from his or her
principal residence or foreclosure on the mortgage of the Participant's
principal residence; or

         (c) Any other circumstance that is determined by the Plan
Administrator, in the Plan Administrator's sole discretion, to constitute an
unforeseeable emergency if an event or circumstance (i) cannot be relieved
through reimbursement and is not covered by insurance, (ii) cannot be reasonably
relieved by the liquidation of the Participant's or Beneficiary's assets, unless
such liquidation itself would cause a severe financial hardship, and (iii) is
consistent with the intent of Treasury Regulation Section 1.457-2(h)(4) and (5).

         7.4 EARLY DISTRIBUTION. Notwithstanding the foregoing provisions of
this Article VII or the provisions of any applicable deferral election, a
Participant may elect to receive a lump-sum payment of any or all of his or her
Account balance prior to the date prescribed in Section 7.1(a). Such payment
shall be made as soon as practicable following the date as of which the
Participant requests such payment. The Plan Administrator shall impose a penalty
for such early payment, in an amount equal to 10% of the Account balance to be
distributed, and such penalty shall be deducted from the distribution and
forfeited by the Participant.



                                       8

         7.5 TAXES. Income taxes and other taxes payable with respect to an
Account shall be deducted from such Account. All federal, state or local taxes
that the Plan Administrator determines are required to be withheld from any
payments made pursuant to this Article 7 shall be withheld.

                                    ARTICLE 8
                               PLAN ADMINISTRATION

         8.1 PLAN ADMINISTRATION AND INTERPRETATION. The Plan Administrator
shall oversee the administration of the Plan. The Plan Administrator shall have
complete control and authority to determine the rights and benefits and all
claims, demands and actions arising out of the provisions of the Plan of any
Participant, Beneficiary, deceased Participant, or other person having or
claiming to have any interest under the Plan. Benefits under the Plan shall be
paid only if the Plan Administrator decides in its discretion that the Eligible
Employee, Participant or Beneficiary is entitled to them. Notwithstanding any
other provision of the Plan to the contrary, the Plan Administrator shall have
complete discretion to interpret the Plan and to decide all matters under the
Plan. Such interpretation and decision shall be final, conclusive and binding on
all Participants and any person claiming under or through any Participant, in
the absence of clear and convincing evidence that the Plan Administrator acted
arbitrarily and capriciously. Any individual serving as Plan Administrator who
is a Participant shall not vote or act on any matter relating solely to himself
or herself. When making a determination or calculation, the Plan Administrator
shall be entitled to rely on information furnished by a Participant, a
Beneficiary, the Employer or a trustee (if any). The Plan Administrator shall
have the responsibility for complying with any reporting and disclosure
requirements of ERISA.

         8.2 POWERS, DUTIES, PROCEDURES. The Plan Administrator shall have such
powers and duties, may adopt such rules and tables, may act in accordance with
such procedures, may appoint such officers or agents, may delegate such powers
and duties, may receive such reimbursements and compensation, and shall follow
such claims and appeal procedures with respect to the Plan as the Plan
Administrator may establish.

         8.3 INFORMATION. To enable the Plan Administrator to perform its
functions, the Employer shall supply full and timely information to the Plan
Administrator on all matters relating to the compensation of Participants, their
employment, retirement, death, termination of employment, and such other
pertinent facts as the Plan Administrator may require.

         8.4 INDEMNIFICATION OF PLAN ADMINISTRATOR. The Employer agrees to
indemnify and to defend to the fullest extent permitted by law any director,
officer or employee who serves as Plan Administrator (including any such
individual who formerly served as Plan Administrator) against all liabilities,
damages, costs and expenses (including reasonable attorneys' fees and amounts
paid in settlement of any claims approved by the Employer in writing in advance)
occasioned by any act or omission to act in connection with the Plan, if such
act or omission is in good faith.

                                    ARTICLE 9
                            AMENDMENT AND TERMINATION

         9.1 AUTHORITY TO AMEND AND TERMINATE. Subject to Section 9.2, the Plan
Committee shall have the right to amend or terminate the Plan at any time. If
the Plan is terminated and a trust is established (as described in Section
10.1), the Company may (a) elect to continue to maintain the trust to pay
benefits hereunder as they become due as if the Plan had not terminated, or (b)
direct the trustee to pay promptly to Participants (or their Beneficiaries) the
balance of their Accounts.

         9.2 EXISTING RIGHTS. No amendment or termination of the Plan shall
adversely affect the rights of any Participant with respect to amounts that have
been credited to his or her Account prior to the later of the date such
amendment or termination is adopted or effective.

                                   ARTICLE 10
                                  MISCELLANEOUS

         10.1 NO FUNDING. The Company intends that the Plan constitute an
"unfunded" plan for tax purposes and for purposes of Title I of ERISA; provided
that the Plan Administrator may authorize the creation of trusts and deposit
therein cash or other property, or make other arrangements to meet the Company's
obligations under the Plan, and further provided that such a trust shall be
established upon a Change in Control, if none has previously been established,
and the Company shall make a contribution to such trust effective as of the date
of the Change in Control in an amount equal to the sum of the value of all
Participant Accounts (including deemed investment gains) under the Plan as of
such date and all contributions made to the Trust as of the date of the Change
in Control shall thereafter be irrevocable until all Accounts under the Plan
have been paid in full. Such trusts or other arrangements shall be consistent
with the unfunded status of the Plan, unless the Plan Administrator otherwise
determines with the consent of each Participant. In the event that such a trust
or other arrangement is established, any Matching Allocations under the Plan may
be made in cash or in property (either in part or in whole), including common
stock of the Company.

         10.2 GENERAL CREDITOR STATUS. The Plan constitutes a mere promise by
the Company to make payments in accordance with the terms of the Plan and
Participants and Beneficiaries shall have the status of general unsecured
creditors of the Company. Nothing in the Plan will be construed to give any
employee or any other person rights to any specific assets of the Company or of
any other person.

         10.3 NON-ASSIGNABILITY. None of the benefits, payments, proceeds or
claims of any Participant or Beneficiary shall be subject to any claim of any
creditor of any Participant or Beneficiary and, in particular, the same shall
not be subject to attachment or garnishment or other legal process by any
creditor of such Participant or Beneficiary, nor shall any Participant or
Beneficiary have any right to alienate, anticipate, commute, pledge, encumber or
assign any of the benefits or payments or proceeds that he or she may expect to
receive, contingently or otherwise under the Plan.

         10.4 LIMITATION OF PARTICIPANT'S RIGHTS. Nothing contained in the Plan
shall confer upon any person a right to be employed or to continue in the employ
of an Employer, or to interfere, in any way, with an Employer's right to
terminate the employment of a Participant in the Plan at any time, with or
without cause.

         10.5 PARTICIPANTS BOUND. Any action with respect to the Plan taken by
the Plan Administrator or a trustee (if any), or any action authorized by or
taken at the direction of the Plan Administrator or a trustee (if any), shall be
conclusive upon all Participants and Beneficiaries entitled to benefits under
the Plan.

         10.6 SATISFACTION OF CLAIMS; UNCLAIMED BENEFITS. Any payment to any
Participant or Beneficiary in accordance with the provisions of the Plan shall,
to the extent thereof, be in full satisfaction of all claims under the Plan
against the Employer, the Plan Administrator and a trustee (if any) under the
Plan, and the Plan Administrator may require such Participant or Beneficiary, as
a condition precedent to such payment, to execute a receipt and release to such
effect. If any Participant or Beneficiary is determined by the Plan
Administrator to be incompetent by reason of physical or mental disability
(including minority) to give a valid receipt and release, the Plan Administrator
may cause the payment or payments becoming due to such person to be made to
another person for his or her benefit without responsibility on the part of the
Plan Administrator, the Employer or a trustee (if any) to follow the application
of such funds. In the case of a benefit payable on behalf of a Participant, if
the Plan Administrator is unable to locate the Participant or beneficiary to
whom such benefit is payable, upon the Plan Administrator's determination
thereof, such benefit shall be forfeited to the Company. Notwithstanding the
foregoing, if subsequent to any such forfeiture the Participant or beneficiary
to whom such benefit is payable makes a valid claim for such benefit, such
forfeited benefit shall be restored to the Plan by the Company.

         GOVERNING LAW AND SEVERABILITY. The Plan shall be construed,
administered, and governed in all respects under and by the laws of the State of
Texas. If any provision is held by a court of competent jurisdiction to be
invalid or unenforceable, the remaining provisions hereof shall continue to be
fully effective.

         10.7 NOT CONTRACT OF EMPLOYMENT. The adoption and maintenance of the
Plan shall not be deemed to be a contract between the Company and any person or
to be consideration for the employment of any person. Nothing herein contained
shall be deemed to give any person the right to be retained in the employ of the
Company or to restrict the right of the Company to discharge any person at any
time nor shall the Plan be deemed to give the Company the right to require any
person to remain in the employ of the Company or to restrict any person's right
to terminate his employment at any time.

         10.8 SEVERABILITY. If any provision of this Plan shall be held illegal
or invalid for any reason, said illegality or invalidity shall not affect the
remaining provisions hereof; instead, each provision shall be fully severable
and the Plan shall be construed and enforced as if said illegal or invalid
provision had never been included herein.

         10.9 HEADINGS. Headings and subheading in the Plan are inserted for
convenience only and are not to be considered in the construction of the
provisions hereof.
