      THIS AMENDMENT, is made and entered into on December 12, 2002, by ALLIED

                                R E C I T A L S:

      1.    The Employer maintains the Allied Waste Industries, Inc. 1993

      2.    The Employer has reserved the right to amend the Plan in whole or in
part; and

      3.    The Employer intends to amend the Plan.

      THEREFORE, the Employer hereby adopts this Amendment as follows:

      1.    The definition of "Code" contained in Section 2(e) of the Plan is
amended by adding the following sentence at the end of that Section:

            Reference in the Plan to any Code section shall be deemed to include
      any amendments or successor provisions to any Section and any treasury
      regulations promulgated thereunder.

      2.    Section 2(k) of the Plan is amended to read as follows:

            "Fair Market Value" of a share of Common Stock on any date is (i)
      the closing sales price on that date (or if that date is not a business
      day, on the immediately preceding business day) of a share of Common Stock
      as reported on the principal securities exchange on which shares of Common
      Stock are then listed or admitted to trading; (ii) if not so reported, the
      average of the closing bid and asked prices for a share of Common Stock on
      that date (or if that date is not a business day, on the immediately
      preceding business day) as quoted on the National Association of
      Securities Dealers Automated Quotation System ("NASDAQ") or (iii) if not
      quoted on NASDAQ, the average of the closing bid and asked prices for a
      share of Common Stock as quoted by the National Quotation Bureau's "Pink
      Sheets" or the National Association of Securities Dealers' OTC Bulletin
      Board System. If the price of a share of Common Stock is not so reported,
      the Fair Market Value of a share of Common Stock shall be determined by
      the Committee in its absolute discretion.

      3.    Section 4 of the Plan is amended by adding the following sentence to
the end of the first paragraph:

            For purposes of grants and awards pursuant to, and the

      "Committee" and "Board" shall be used interchangeably.

      4.    The fifth paragraph of Section 4 of the Plan is amended to read as
follows:

            Except as provided in Section 6(e)(5) hereof, whether an authorized
      leave of absence, or absence in military or government service, shall

      in its absolute discretion.

      5.    Section 4 of the Plan is amended by adding the following new
paragraph to the end of that Section:

            The Committee or Board may delegate to an officer of the Corporation
      the authority to make decisions pursuant to this Plan; provided, however,
      that no such delegation may be made that would cause any award or other
      transaction under the Plan to cease to be exempt from Section 16(b) of the
      Exchange Act. The Committee may authorize any one or more of its members
      or any officer of the Company to execute and deliver documents on behalf
      of the Committee.

      6.    The second sentence in Section 6(b) of the Plan is amended to read

            Except as provided in Section 6(d) hereof and subject to the
      adjustments provided for in Section 11 hereof, the exercise price of an
      Incentive Stock Option granted under the Plan shall not be less than 100%
      of the Fair Market Value of a share of Common Stock on the date on which
      such Option is granted.

      7.    Section 6(c)(3) of the Plan is amended to read as follows:

            An Option shall be exercised by delivering notice to the Company's
      principal office, to the attention of its Secretary, along with the
      agreement evidencing the Option and payment for shares of Common Stock to
      be purchased upon the exercise of the Option. The notice must specify the
      number of shares of Common Stock with respect to which the Option is being
      exercised and must be signed by the Participant. Payment shall be made
      either (A) in cash, by certified check, bank cashier's check or wire
      transfer, (B) subject to the approval of the Committee, in shares of
      Common Stock owned by the Participant for a period of at least six months
      prior to the effective date on which the Option is exercised and valued at
      their Fair Market Value on the effective date of such exercise, (C)
      subject to the approval of the Committee, in the form of a "cashless
      exercise" (as described below) or (D) subject to the approval of the
      Committee, in any combination of the foregoing. Any payment in shares of
      Common Stock shall be effected by the delivery of such shares to the
      Secretary of

                                                                               2
<PAGE>
      the Company, duly endorsed in blank or accompanied by stock powers duly
      executed in blank, together with any other documents and evidences as the
      Secretary of the Company shall require from time to time. The effective
      date on which an Option is exercised shall be established by the Secretary
      and shall occur within an administrative reasonable period of time (but no
      later than five business days) after the Secretary receives the notice,
      agreement, and payment referred to above. Prior to the exercise date, the
      Optionee may withdrawal the notice, in which case the Option will not be
      exercised.

            The cashless exercise of an Option shall be pursuant to procedures
      whereby the Participant by written notice, directs (A) an immediate market
      sale or margin loan respecting all or a part of the shares of Common Stock
      to which he is entitled upon exercise pursuant to an extension of credit
      by a brokerage firm (or other party that is not affiliated with the
      Company) of the exercise price, (B) the delivery of the shares of Common
      Stock directly from the Company to a brokerage firm and (C) delivery of
      the exercise price from the sale or the margin loan proceeds from the
      brokerage firm directly to the Company.

      8.    Section 6(c)(5) of the Plan is amended to read as follows:

            Certificates for shares of Common Stock purchased upon the exercise
      of an Option shall be issued in the name of the Participant or permitted
      transferee of the Participant and delivered to the Participant or
      permitted transferee as soon as practicable following the later of (A) the
      effective date on which the Option is exercised or (B) the date
      withholdings are made by the Company (or an amount sufficient to satisfy
      such withholdings are received by the Company) with respect to the Option
      that is exercised; provided, however, that such delivery shall be effected
      for all purposes when a stock transfer agent of the Company shall have
      deposited such certificates in the United States mail, addressed to the
      Participant or permitted transferee. If withholdings are to be transmitted
      to the Company and are not timely received, to satisfy its withholding
      obligation, the Company may withhold a portion of the shares of Common
      Stock that would otherwise be issued to the Participant upon the exercise
      of the Option, sell such shares, and use the proceeds from such shares to
      satisfy the Company's withholding obligations.

      9.    Section 6(c)(6) of the Plan is amended to read as follows:

            Except as set forth in this Section 6(c)(6), during the lifetime of
      a Participant, each Option granted to him shall be exercisable only by him
      or a broker-dealer acting on his behalf pursuant to Section 6(c)(4). No
      Option shall be assignable or transferable for value. Each Option may be
      assigned by a Participant by will or by the laws of descent and
      distribution, or pursuant to a Qualified Domestic Relations Order.
      Non-Qualified Stock Options may be assigned to: (A) a child, stepchild,
      grandchild, sibling, niece, nephew, mother-in-law, father-in-law,
      son-in-law, daughter-in-law, brother-in-law or sister-in-law, including
      adoptive relationships, (B) any person sharing the Participant's household
      (other than a tenant or employee), (C) a trust in which the persons
      described in (A) or (B) (or the Participant) hold more than 50% of the
      beneficial interest or (D) a private foundation in which the persons
      described in (A) or (B) (or the Participant) own more than 50% of the
      voting interests. A transfer to any entity in which more than 50% of the
      voting interests are

                                                                               3
<PAGE>
      owned by the persons described in (A) or (B) (or the Participant) in
      exchange for an interest in that entity shall not constitute a transfer
      for value.

      10.   Section 6(e) of the Plan is amended by adding the following new
subparagraph:

            (5) A Participant's employment with the Company shall be deemed
      terminated if the Participant's leave of absence (including military or
      such leave or other bona fide leave of absence) extends for more than 90
      days and the Participant's continued employment with the Company is not
      guaranteed by contract or statute.

      11.   Section 6 of the Plan is amended by adding the following new
paragraphs to the end of that Section:

            (f) Buyout of Options. The Committee may at any time (i) offer to
      buy out for a payment of cash or cash equivalents an Option previously
      granted, or (ii) authorize a holder of an Option to elect to cash out an
      Option previously granted, in either case at such time and based upon such
      terms and conditions as the Committee shall establish.

            (g) Definitions. For purposes of this Section 6, "month" means 31
      calendar days beginning with the calendar day on which the relevant event
      occurs, and "year" means 365 calendar days beginning with the calendar day
      on which the relevant event occurs.

      12.   The first sentence in the first paragraph of Section 7 of the Plan
is amended to read as follows:

            The Committee may grant shares of Restricted Stock pursuant to the
      Plan for such consideration as the Committee may determine, including
      (without limitation) cash, cash equivalents, full-recourse promissory
      notes, past services or future services.

      13.   Section 7(c) of the Plan is amended to read as follows:

            (c) Transfers Prior to Vesting. Prior to the vesting of a share of
      Restricted Stock, a Participant shall be entitled to assign or transfer
      such share and all of the rights related thereto to the extent permitted
      by this Section 7(c). Any such assignment or transfer must not be for
      value. Any such assignment or transfer is limited to an assignment or
      transfer to: (i) a child, stepchild, grandchild, sibling, niece, nephew,
      mother-in-law, father-in-law, son-in-law, daughter-in-law, brother-in-law
      or sister-in-law, including adoptive relationships, (ii) any person
      sharing the Participant's household (other than a tenant or employee),
      (iii) a trust in which the persons described in (i) or (ii) (or the
      Participant) hold more than 50% of the beneficial interest or (iv) a
      private foundation in which the persons described in (i) or (ii) (or the
      Participant) own more than 50% of the voting interests. A transfer to any
      entity in which more than 50% of the voting interests are owned by the
      persons described in (i) or (ii) (or the Participant) in exchange for an
      interest in that entity shall not constitute a transfer for value.

                                                                               4

      16.   Section 7 is amended by adding the following new paragraph to the
end of that Section:

            (h) Voting and Dividend Rights. The holders of Restricted Stock
      awarded under this Plan shall have the same voting, dividend and other
      rights as the Company's other stockholders (except that the transfer of
      such shares is limited in accordance with Section 7(c) prior to vesting);
      provided, however, that the Committee may require in the agreement
      granting the Restricted Stock that cash dividends be invested in
      additional shares of Restricted Stock, subject to the same conditions and
      restrictions as the Incentive Award with respect to which the dividends
      were paid.

      17.   The last sentence in Section 8(d)(1) of the Plan is amended to read

            Such portion may equal zero, and any non-vested shares shall be
      forfeited as of the commencement of business on the date of the
      Participant's termination of employment.

      18.   Section 14 of the Plan is amended by adding the following new
paragraph to the end of that Section:

            (c) It is intended that the Plan and any grant of an Incentive Award
      made to a person subject to Section 16 of the Exchange Act meet all of the
      requirements of Rule 16b-3 promulgated thereunder. If any provision of the
      Plan or any Incentive Award would disqualify the Plan or the Incentive
      Award, or would otherwise not comply with Rule 16b-3, such provision or
      Incentive Award shall be construed or deemed amended to conform to Rule
      16b-3 to the extent permitted by applicable law and deemed advisable by
      the Board.

      19.   Section 18 of the Plan is amended to read as follows:

            Upon the death of a Participant, outstanding Incentive Awards
      granted to such Participant may be exercised only by the executors or
      administrators of the Participant's estate or by any person or persons who
      shall have acquired such right to exercise by will or by the laws of
      descent and distribution or by assignment or transfer from the Participant
      as contemplated by Sections 6(c)(6) and 7(c) above. No transfer by will or
      the laws of descent

                                                                               5
<PAGE>
      and distribution, or as contemplated by Sections 6(c)(6) and 7(c) above,
      of any Incentive Award, or the right to exercise any Incentive Award,
      shall be effective to bind the Company unless the Committee shall have
      been furnished with (a) written notice thereof and with a copy of the
      will, assignment, or transfer document and/or such evidence as the
      Committee may deem necessary to establish the validity of the transfer and
      (b) an agreement by the transferee to comply with all the terms and
      conditions of the Incentive Award that are or would have been applicable
      to the Participant and to be bound by the acknowledgments made by the
      Participant in connection with the grant of the Incentive Award.

      20.   The Plan is amended by adding the following new Section:

      22.   DEFERRAL OF DELIVERY OF SHARES

            The Committee (in its sole discretion) may permit or require a
      Participant who receives an Incentive Award to have Common Shares that
      would otherwise be delivered to the Participant converted into a deferred
      compensation account established for such Participant by the Committee as
      an entry on the Company's books. Such amounts shall be determined by
      reference to the Fair Market Value of such Common Shares as of the date
      they otherwise would have been delivered to the Participant. A deferred
      compensation account established under this Section 22 may be credited
      with interest or other forms of investment return, as determined by the
      Committee. A Participant for whom such an account is established shall
      have no rights other than those of a general creditor of the Company. Such
      an account shall represent an unfunded and unsecured obligation of the
      Company and shall be subject to the terms and conditions of the applicable
      agreement between the Participant and the Company; provided, however, that
      the Committee may elect to establish a trust for the purpose of securing
      any such obligation. If the deferral of Incentive Awards is permitted or
      required, the Committee (in its sole discretion) may establish rules,
      procedures and forms pertaining to such Incentive Awards, including
      (without limitation) the settlement of deferred compensation accounts
      established under this Section 22.

      21.   The Plan is amended by adding the following new Section:

      23.   COMPLIANCE WITH THE EXCHANGE ACT

            With respect to persons subject to Section 16 of the Exchange Act,
      transactions under this Plan are intended to comply with all applicable
      conditions of Rule 16b-3 or its successors under the Exchange Act. To the
      extent any provisions of the Plan or action by the Committee or Board
      fails to so comply, it shall be deemed null and void, to the extent
      permitted by law and deemed advisable by the Committee or Board.

      22.   The Effective Date of this Amendment shall be December 12, 2002.

                                                                               6

      23.   Except as amended, all of the terms and conditions of the Plan shall
      remain in full force and effect.
