                 SECTION 2.  Intercreditor Agreement.

the Agents during the Enforcement Stay Period with respect to such Enforcement
Notice, provided that during such Enforcement Stay Period, demand for payment
may be made, the maturity of any portion of the Lender's Claim may be
accelerated, and any commitment to extend credit pursuant to the Credit

provided that such Enforcement Stay Period, demand for payment may be made.
Notwithstanding the foregoing, the Lender Parties and WMX may each commence
Enforcement without giving a prior Enforcement Notice or prior to the
expiration of an Enforcement Stay Period if a petition is filed by or against
either Borrower for relief under title 11 of the United States Code, as amended
from time to time, or under any similar state statute.  Each Lender Group may
join with the other Lender Group in such other Lender Group's Enforcement.

                 The Agents and WMX each agree to use good faith efforts to
cooperate with respect to any proposed or continuing Enforcement in order to
maximize the amount of proceeds obtained therefrom.  The Agents and WMX agree
to exchange, upon request, information regarding the Collateral (including, but
not limited to, appraisals and third party offers to purchase, or inquiries as
to, the Collateral).  Each Lender Group agrees to use its best efforts to
notify the other Lender Group, prior to incurring any material expense in
connection with Enforcement, or with any appraisal of or evaluation of the
Collateral.

                 2.02.    Sale Notice.  If either Lender Group intends to
conduct a public or private sale of any of the Collateral, then such Lender
Group shall provide a Sale Notice with respect to such Collateral being sold.
To be effective, such Sale Notice must be delivered in one of the manners set
forth in Section 3.01 hereof, with an actual or deemed receipt date (pursuant
to the provisions of Section 3.01) at least ten (10) days prior to such
proposed sale.

                 2.03.    The Collateral; Distribution of Proceeds of
Collateral.  The Agents and WMX each acknowledge and agree that the Borrowers
have, pursuant to the Lender Documents and the WMX Documents, granted liens and
security interests in all of the Collateral to both the Issuing and Paying
Agent (for the benefit of the Lenders) and WMX.  To the extent that either
Agent or WMX receives at any time while a WMX Claim is outstanding, or at any
time after the obligations under the Credit Agreement have become due by their
terms at maturity or the Administrative Agent has accelerated the maturity of
the obligations under the Credit Agreement and terminated the Banks' agreement
to lend under the Credit Agreement, whether or not a payment has been made by
WMX under the WMX Guaranty, proceeds of any Collateral, or payments





                                      -5-
   6
in respect of the WMX Claim or the Lenders' Claim (including any amounts
received by exercise of set-off), such proceeds or payments (net of the
reasonable costs of enforcement and collection) shall be held in trust (until
distributed or retained as set forth below) and shall be promptly paid (or
retained) as follows:

                          (a)     The Lenders' Pro Rata Share of such net
         proceeds or payments shall be paid to (or retained by) the Agents; and

                          (b)     WMX' Pro Rata Share of such net proceeds or
         payments shall be paid to (or retained by) WMX.

Amounts paid to or retained by the Agents pursuant to clause (a) above shall be
applied in accordance with the Lender Documents, and amounts paid to or
retained by WMX pursuant to clause (b) above shall be applied in accordance
with the WMX Documents; provided, that any amounts so paid to or retained by
WMX prior to WMX's having made payment under the WMX Guaranty shall be held by
WMX as cash collateral for the Borrowers' contingent obligations under the
Reimbursement Agreement.  By its consent hereto, each of the Borrowers consents
to WMX' so holding or retaining any such proceeds as cash collateral, agrees
that such cash collateral need not be segregated, and agrees that WMX may apply
such cash collateral to the Borrowers' obligation to reimburse WMX for any
payment made by WMX under the WMX Guaranty.

                 Upon the Lenders' receipt of payment in full in cash
(including any amounts received by exercise of any set-off) of the Lenders'
Claim while the WMX Claim is still outstanding, all further proceeds of
Collateral shall be paid to or retained by WMX and applied toward satisfaction
of the WMX Claim, and upon payment in full in cash (including amounts received
by exercise of any set-off) of the WMX Claim while the Lenders, Claim is still
outstanding, all further proceeds of Collateral shall be paid to or retained by
the Agents in satisfaction of the Lenders' Claim.  If both the Lenders' Claim
and the WMX Claim shall have been paid in full (in cash), all further proceeds
of Collateral shall be paid to the Borrowers or as otherwise required by law.

                 2.04.    Invalidated Payments.  To the extent that any
payments on the Lenders' Claim or the WMX Claim, or any application of any
proceeds of Collateral to the reduction of the Lenders' Claims or the WMX
Claim, are subsequently invalidated, declared to be fraudulent or preferential,
set aside and/or required to be repaid to a trustee, receiver or any other
Person under any bankruptcy law, state or federal law, common law, or equitable
cause, then, to the extent of such payment or proceeds application, the
Lenders' Claim or the WMX Claim, or part thereof, as the case may be, intended
to be satisfied shall be revived and continue in full force and effect as if
such payments or proceeds had not been received.

                 2.05.    Additional Collateral.  To the extent that either
Agent, any other Lender Party or WMX is granted a lien upon or security
interest in any additional real or personal property to secure the repayment or
performance of the Lenders' Claim or the WMX Claim, such additional collateral
shall be deemed Collateral hereunder, subject to all of the terms and
provisions hereof.

                 2.06.    Notice of Defaults.  (a) The Agents and WMX each
agree to use their good faith efforts to give to the other copies of any notice
of the occurrence or existence of a Lender Default or a Reimbursement Default,
as applicable, sent simultaneously with the sending of such notice to the
Borrowers, but the failure to do so shall not affect the validity of any such
notice to the Borrowers or create a cause of action against the party failing
to give such notice or create any claim or right on behalf of any third party.
The sending of any such notice by or on behalf of a Lender Group shall not give
the other Lender Group any obligation or right to cure such Lender Default or
Reimbursement Default, as applicable.

                 (b)      WMX agrees to give to each of the Agents notice of
any default or event of default (which continues beyond any applicable grace
period) under any indebtedness of WMX with a principal amount of $50,000,000 or
more, or under any of the documents executed in connection with any such
indebtedness, such notice to be given within ten (10) days after WMX has notice
of any such default or event of default, provided, however, that WMX shall have
no liability to the Lender Parties for failure to give such notice with respect
to indebtedness of WMX with a principal amount of less than 5% of the
stockholders' equity of WMX.

                 2.07.    Agency for Perfection.  The Agents hereby appoint
WMX, and WMX hereby appoints each of the Agents, as agent for purposes of
perfecting their respective security interests in Collateral.  In the event any
party hereto obtains possession of any Collateral, any proceeds arising
therefrom shall be applied in accordance with Section 2.03 above.  Without
limiting the generality of the foregoing, the Issuing and Paying Agent hereby
agrees that it shall hold the stock certificates evidencing the issued and
outstanding stock pledged pursuant to the "Pledge Agreement" (as defined in the
Credit Agreement) as bailee for WMX for purposes of perfecting WMX's lien with
respect to such stock as granted under the WMX Documents.  Upon indefeasible
payment in full in cash of the Lenders' Claim, the Issuing and Paying Agent
hereby agrees to deliver the certificates evidencing such stock to WMX, unless
the Issuing and Paying Agent has received prior written notice from WMX that
the WMX Claim has been paid in full.  By its consent hereto, each of the
Borrowers hereby authorizes the Issuing and Paying Agent to so deliver the
certificates evidencing such stock to WMX upon indefeasible payment in full in
cash of the Lenders' Claim and the Issuing and Paying Agent shall have no
liability to either Borrower with respect to such





                                      -7-
   8
delivery.  Notwithstanding the foregoing, neither Lender Group makes any
representation to the other Lender Group with respect to the perfection or
priority of its security interests in any of the Collateral, and neither Lender
Group shall be liable to the other for failure to properly perfect its security
interests in any of the Collateral.

                 SECTION 3.  Miscellaneous.

                 3.01.    Notices.  All notices and other communications

                 3.02.    Contesting Liens or Security Interests.  No Lender
Party shall contest the validity, perfection, priority or enforceability of any
lien or security interest granted by either Borrower to WMX, or petition any
court to equitably subordinate the WMX Claim, and WMX shall not contest the
validity, perfection, priority or enforceability of any lien or security
interest granted by either Borrower to any Lender Party or petition any court
to equitably subordinate the Lenders' Claim.   All parties agree all future
security interests granted in any of the Collateral during the term of this
Intercreditor Agreement are subject to the terms of this Intercreditor
Agreement.

                 3.03.    No Additional Rights for Borrower or Other Parties
Hereunder.  This Agreement sets forth certain rights and obligations of the two
Lender Groups as between themselves, and is solely for their benefit.  In no
event shall the Borrowers or any third party obtain any rights with respect to
any Lender Party or WMX as a result of this Agreement.  Without limiting the
generality of the foregoing, if the Agents or WMX shall fail to comply with the
terms of this Agreement, the Borrowers agree that they shall not use such
failure as a defense to any Enforcement under the Lender Documents and/or the
WMX Documents nor assert such failure as a counterclaim or basis for set-off or
recoupment of any kind or nature.

                 3.04.    Independent Credit Investigations.  Neither Lender
Group, nor any of the directors, officers, agents or employees of any member of
either Lender Group, shall be responsible to the other Lender Group or to any
other Person for either Borrower's solvency, financial condition or ability to
repay the Lenders' Claim or the WMX Claim, or for statements of either
Borrower, oral or written, or for the validity, sufficiency or enforceability
of the Lenders' Claim or the WMX Claim, the Lenders' Documents, the WMX
Documents, or any liens or security interests granted by either Borrower to any
Lender Party or WMX in connection therewith.  Each Lender Group has entered
into its respective financing agreements with the Borrowers based upon its own
independent investigation, and makes no warranty or representation to, nor does
it rely upon any warranty or representation of, the other Lender Group with
respect to matters identified or referred to in this Section 3.04.


                 3.05.    Amendments to Financing Arrangements; Release of
Collateral.  Each Lender Group, at any time and from time to time, may enter
into such agreement or agreements with either Borrower as such Lender Group may
deem proper, extending the time of payment of or renewing or otherwise
altering, in accordance with the terms of such documents, the terms of the
Lender Documents (in the case of the Lender Parties) or the WMX Documents (in
the case of WMX) or affecting the security underlying any or all of the
Lenders' Claim (in the case of the Lender Parties) or the WMX Claim (in the
case of WMX), and may





                                      -9-
   10
exchange, sell, release, surrender or otherwise deal with any such security,
without in any way thereby impairing or affecting this Agreement. The Agents
and WMX shall each use its good faith efforts to notify the other of any
amendment of or modification to the Lender Documents or the WMX Documents, as
the case may be, but the failure to do so shall not create a cause of action
against the party failing to give such notice or create any claim or right on
behalf of any third party.  The Agents and WMX shall, upon request of the
other, provide copies of all such modifications or amendments and copies of all
other documentation relevant to the Collateral hereunder.

                 3.06.    Amendments.  All modifications or amendments of this
Agreement must be in writing and duly executed by an authorized officer of each
party hereto to be binding and enforceable.

                 3.07.    Term.  This Agreement shall be effective upon the
execution hereof by the parties hereto, and shall continue in effect and may
not be revoked by any, of the parties hereto prior to the earliest of (a) the
indefeasible payment in full in cash of the Lenders' Claims and the termination
of the Lender Documents, (b) the indefeasible payment in full in cash of the
WMX Claim and the termination of the WMX Guaranty and the WMX Documents, and
(c) the termination of the WMX Guaranty in accordance with its terms without
the WMX Guaranty having been drawn on.  The Agreement shall terminate upon the
earlier to occur of (a), (b) and (c) above, provided that the provisions of the
last paragraph of Section 2.03 shall survive such termination.

                 3.08.    Successors and Assigns.  This Agreement shall be
binding upon and inure to the benefit of the respective successors and assigns
of each of the parties hereto, but does not otherwise create, and shall not be
construed as creating, any rights enforceable by any Person other than the two
Lender Groups.

                 3.9.     Governing Law.  This Agreement shall be governed as
to validity, interpretation, enforcement and effect by the laws (including
Section 5-1401 of the General Obligations Law, but otherwise without regard to
conflicts of law principles) and decisions of the State of New York.

                 3.10.  Execution in Counterparts.  This Agreement may be
executed in any number of counterparts and by different parties hereto in
separate counterparts each of which when so executed shall be deemed to be an
original and all of which taken together shall constitute one and the same
agreement.
