         surplus or paid-in surplus, and all other distributions (other than
         distributions referred to in the preceding sentence) made on or in
         respect of the Pledged Securities, whether paid or payable in cash or
         otherwise, whether resulting from a subdivision, combination or
         reclassification of the outstanding Equity Interests of the issuer of
         any Pledged Securities or received in exchange for Pledged Securities
         or any part thereof, or in redemption thereof, or as a result of any
         merger, consolidation, acquisition or other exchange of assets to which
         such issuer may be a party or otherwise, shall be and become part of
         the Collateral, and, if received by any Subsidiary Pledgor, shall not
         be commingled

<PAGE>

                                                                               9

         by such Subsidiary Pledgor with any of its other funds or property but
         shall be held separate and apart therefrom, shall be held in trust for
         the benefit of the Collateral Trustee and shall be forthwith delivered
         to the Collateral Trustee in the same form as so received (with any
         necessary endorsement).

         (b) Upon the occurrence and during the continuance of an Event of
Default, all rights of any Subsidiary Pledgor to dividends, interest or
principal that such Subsidiary Pledgor is authorized to receive pursuant to
paragraph (a)(iii) above shall cease, and all such rights shall thereupon become
vested in the Collateral Trustee, which shall have the sole and exclusive right
and authority to receive and retain such dividends, interest or principal. All
dividends, interest or principal received by the Subsidiary Pledgor contrary to
the provisions of this Section 6 shall be held in trust for the benefit of the
Collateral Trustee, shall be segregated from other property or funds of such
Subsidiary Pledgor and shall be forthwith delivered to the Collateral Trustee
upon demand in the same form as so received (with any necessary endorsement).
Any and all money and other property paid over to or received by the Collateral
Trustee pursuant to the provisions of this paragraph (b) shall be retained by
the Collateral Trustee in an account to be established by the Collateral Trustee
upon receipt of such money or other property and shall be applied in accordance
with the provisions of Section 8. After all Events of Default have been cured or
waived and the Borrower has delivered to the Collateral Trustee certificates to
that effect, the Collateral Trustee shall, within five Business Days after all
such Events of Default have been cured or waived, repay to each Subsidiary
Pledgor all cash dividends, interest or principal (without interest) that such
Subsidiary Pledgor would otherwise be permitted to retain pursuant to the terms
of paragraph (a)(iii) above and which remain in such account after application
in accordance with Section 8.

         (c) Upon the occurrence and during the continuance of an Event of
Default, all rights of any Subsidiary Pledgor to exercise the voting and
consensual rights and powers it is entitled to exercise pursuant to paragraph
(a)(i) of this Section 6, and the obligations of the Collateral Trustee under
paragraph (a)(ii) of this Section 6, shall cease, and all such rights shall
thereupon become vested in the Collateral Trustee, which shall have the sole and
exclusive right and authority to exercise such voting and consensual rights and
powers; provided that the Collateral Trustee shall, at its sole discretion (or
with the consent of the Requisite Secured Parties, if the Collateral Trustee so
elects), have the right from time to time following and during the continuance
of an Event of Default to permit the Subsidiary Pledgors to exercise such
rights. After all Events of Default have been cured or waived, such Subsidiary
Pledgor will have the right to exercise the voting and consensual rights and
powers that it would otherwise be entitled to exercise pursuant to the terms of
paragraph (a)(i) above.

         SECTION 7. Remedies upon Default. Upon the occurrence and during the
continuance of an Event of Default, subject to applicable regulatory and legal
requirements, the Collateral Trustee may sell or otherwise transfer or dispose
of the Collateral, or any part thereof, at a public or private sale or at any
broker's board or on any securities exchange, for cash, upon credit or for
future delivery as the Collateral Trustee shall deem appropriate. The Collateral
Trustee shall be authorized at any such sale (if it deems it advisable to do so)
to restrict the prospective bidders or purchasers to

<PAGE>

                                                                              10

Persons who will represent and agree that they are purchasing the Collateral for
their own account for investment and not with a view to the distribution or sale
thereof, and upon consummation of any such sale the Collateral Trustee shall
have the right to assign, transfer and deliver to the purchaser or purchasers
thereof the Collateral so sold. Each such purchaser at any such sale shall hold
the property sold absolutely free from any claim or right on the part of any
Subsidiary Pledgor and, to the extent permitted by applicable law, the
Subsidiary Pledgors hereby waive all rights of redemption, stay, valuation and
appraisal any Subsidiary Pledgor now has or may at any time in the future have
under any rule of law or statute now existing or hereafter enacted.

         The Collateral Trustee shall give the Borrower and each applicable
Subsidiary Pledgor 10 days' prior written notice (which each Subsidiary Pledgor
agrees is reasonable notice within the meaning of Section 9-611 of the UCC or
its equivalent in other jurisdictions) of the Collateral Trustee's intention to
make any sale of such Subsidiary Pledgor's Collateral. Such notice, in the case
of a public sale, shall state the time and place for such sale and, in the case
of a sale at a broker's board or on a securities exchange, shall state the board
or exchange at which such sale is to be made and the day on which the
Collateral, or portion thereof, will first be offered for sale at such board or
exchange. Any such public sale shall be held at such time or times within
ordinary business hours and at such place or places as the Collateral Trustee
may fix and state in the notice of such sale. At any such sale, the Collateral,
or portion thereof, to be sold may be sold in one lot as an entirety or in
separate parcels, as the Collateral Trustee may (in its sole and absolute
discretion) determine. The Collateral Trustee shall not be obligated to make any
sale of any Collateral if it shall determine not to do so, regardless of the
fact that notice of sale of such Collateral shall have been given. The
Collateral Trustee may, without notice or publication, adjourn any public or
private sale or cause the same to be adjourned from time to time by announcement
at the time and place fixed for sale, and such sale may, without further notice,
be made at the time and place to which the same was so adjourned. In case any
sale of all or any part of the Collateral is made on credit or for future
delivery, the Collateral so sold may be retained by the Collateral Trustee until
the sale price is paid in full by the purchaser or purchasers thereof, but the
Collateral Trustee shall not incur any liability in case any such purchaser or
purchasers shall fail to take up and pay for the Collateral so sold and, in case
of any such failure, such Collateral may be sold again upon like notice. At any
public (or, to the extent permitted by applicable law, private) sale made
pursuant to this Section 7, any Secured Party may bid for or purchase, free from
any right of redemption, stay or appraisal on the part of any Subsidiary Pledgor
(all said rights being also hereby waived and released), the Collateral or any
part thereof offered for sale and may make payment on account thereof by using
any claim then due and payable to it from such Subsidiary Pledgor as a credit
against the purchase price, and it may, upon compliance with the terms of such
sale, hold, retain and dispose of such property without further accountability
to such Subsidiary Pledgor therefor. For purposes hereof, (a) a written
agreement to purchase the Collateral or any portion thereof shall be treated as
a sale thereof, (b) the Collateral Trustee shall be free to carry out such sale
pursuant to such agreement and (c) such Subsidiary Pledgor shall not be entitled
to the return of the Collateral or any portion thereof subject thereto,
notwithstanding the fact that after the Collateral Trustee shall have entered
into such an agreement all Events of Default shall have been remedied and the
Obligations paid in

<PAGE>

                                                                              11

full. As an alternative to exercising the power of sale herein conferred upon
it, the Collateral Trustee may proceed by a suit or suits at law or in equity to
foreclose upon the Collateral and to sell the Collateral or any portion thereof
pursuant to a judgment or decree of a court or courts having competent
jurisdiction or pursuant to a proceeding by a court-appointed receiver. Any sale
pursuant to the provisions of this Section 7 shall be deemed to conform to the
commercially reasonable standards as provided in Section 9-610(b) of the UCC or
its equivalent in other jurisdictions.

         SECTION 8. Application of Proceeds of Sale. The Collateral Trustee
shall apply the proceeds of any collection or sale of the Collateral, as well as
any Collateral consisting of cash, in the manner set forth in the Collateral
Trust Agreement; provided, however, that if the Collateral Trust Agreement shall
not be in effect, such proceeds and cash shall be applied as follows:

                  FIRST, to the payment of all costs and expenses incurred by
         the Agent or the Collateral Trustee (in its capacity as such hereunder
         or under any other Loan Document) in connection with such collection or
         sale or otherwise in connection with this Agreement or any of the
         Obligations, including all court costs and the fees and expenses of its
         agents and legal counsel, the repayment of all advances made by the
         Collateral Trustee or any Secured Party hereunder or under any other
         Loan Document on behalf of any Subsidiary Pledgor and any other costs
         or expenses incurred in connection with the exercise of any right or
         remedy hereunder or under any other Loan Document;

                  SECOND, to the payment in full of the Credit Agreement
         Obligations (the amounts so applied to be distributed among the holders
         of the Credit Agreement Obligations pro rata in accordance with the
         amounts of the Credit Agreement Obligations owed to them on the date of
         any such distribution); and

                  THIRD, to the Subsidiary Pledgors, their successors or
         assigns, or as a court of competent jurisdiction may otherwise direct.

The Collateral Trustee shall have absolute discretion as to the time of
application of any such proceeds, moneys or balances in accordance with this
Agreement. Upon any sale of the Collateral by the Collateral Trustee (including
pursuant to a power of sale granted by statute or under a judicial proceeding),
the receipt of any such proceeds, moneys or balances by the Collateral Trustee
or of the officer making the sale shall be a sufficient discharge to the
purchaser or purchasers of the Collateral so sold and such purchaser or
purchasers shall not be obligated to see to the application of any part of the
purchase money paid over to the Collateral Trustee or such officer or be
answerable in any way for the misapplication thereof.

         SECTION 9. Reimbursement of Collateral Trustee. (a) Each Subsidiary
Pledgor jointly and severally agrees to pay upon demand to the Collateral
Trustee the amount of any and all reasonable expenses, including the reasonable
fees, other charges and disbursements of a single counsel in New York and such
other local or special counsel as may be reasonably necessary in connection
therewith and of any experts or agents, that

<PAGE>

                                                                              12

the Collateral Trustee may incur in connection with (i) the administration of
this Agreement, (ii) the custody or preservation of, or the sale of, collection
from, or other realization upon, any of the Collateral, (iii) the exercise or
enforcement of any of the rights of the Collateral Trustee hereunder or (iv) the
failure by such Subsidiary Pledgor to perform or observe any of the provisions
hereof.

         (b) Without limitation of its indemnification obligations under the
other Loan Documents, each Subsidiary Pledgor agrees to jointly and severally
indemnify the Collateral Trustee, the other Indemnitees (as defined in Section
9.03(b) of the Credit Agreement), the BFI Trustee, the AWNA Trustee and the 2001
Indenture Trustee (collectively, the "Shared Collateral Indemnitees") against,
and hold each Indemnitee harmless from, any and all losses, claims, damages,
liabilities and related expenses, including reasonable fees of a single counsel
in New York and such other local and special counsel as may be reasonably
necessary in connection therewith, other charges and disbursements, incurred by
or asserted against any Indemnitee arising out of, in any way connected with, or
as a result of, (i) the execution or delivery of this Agreement, the AWNA
Indenture, any 2001 Indenture and the BFI Indenture or any other Loan Document
or any agreement or instrument contemplated hereby or thereby, the performance
by the parties hereto of their respective obligations hereunder or thereunder or
the consummation of the Transactions and the other transactions contemplated
hereby or thereby or (ii) any claim, litigation, investigation or proceeding
relating to any of the foregoing, whether or not any Indemnitee is a party
thereto; provided that such indemnity shall not, as to any Shared Collateral
Indemnitee, be available to the extent that such losses, claims, damages,
liabilities or related expenses are determined by a court of competent
jurisdiction by a final nonappealable judgment to have resulted from the gross
negligence or wilful misconduct of such Shared Collateral Indemnitee.

         (c) Any amounts payable as provided hereunder shall be additional
Obligations secured hereby and by the other Security Documents. The provisions
of this Section 9 shall remain operative and in full force and effect regardless
of the termination of this Agreement, any other Loan Document, the BFI
Indenture, the AWNA Indenture or any 2001 Indenture, the consummation of the
transactions contemplated hereby, the repayment of any of the Obligations, the
invalidity or unenforceability of any term or provision of this Agreement, any
other Loan Document, the BFI Indenture, the AWNA Indenture or any 2001 Indenture
or any investigation made by or on behalf of the Collateral Trustee or any other
Secured Party. All amounts due under this Section 9 shall be payable on written
demand therefor and shall bear interest at the rate specified in Section 2.13 of
the Credit Agreement.

         SECTION 10. Collateral Trustee Appointed Attorney-in-Fact. Each
Subsidiary Pledgor hereby appoints the Collateral Trustee the attorney-in-fact
of such Subsidiary Pledgor for the purpose of carrying out the provisions of
this Agreement and taking any action and executing any instrument that the
Collateral Trustee may deem necessary or advisable to accomplish the purposes
hereof, which appointment is irrevocable and coupled with an interest; provided
that the Collateral Trustee shall have such right, only upon the occurrence and
during the continuance of an Event of Default of which the Collateral Trustee
shall have received written notice from the Agent or a Trustee under

<PAGE>

                                                                              13

the applicable Debt Instrument, which right shall include the full power of
substitution either in the Collateral Trustee's name or in the name of such
Subsidiary Pledgor, to ask for, demand, sue for, collect, receive and give
acquittance for any and all moneys due or to become due under and by virtue of
any Collateral, to endorse checks, drafts, orders and other instruments for the
payment of money payable to such Subsidiary Pledgor representing any interest or
dividend or other distribution payable in respect of the Collateral or any part
thereof or on account thereof and to give full discharge for the same, to
settle, compromise, prosecute or defend any action, claim or proceeding with
respect thereto, and to sell, assign, endorse, pledge, transfer and to make any
agreement respecting, or otherwise deal with, the same; provided, however, that
nothing herein contained shall be construed as requiring or obligating the
Collateral Trustee to make any commitment or inquiry as to the nature or
sufficiency of any payment received by the Collateral Trustee, or to present or
file any claim or notice, or to take any action with respect to the Collateral
or any part thereof or the moneys due or to become due in respect thereof or any
property covered thereby. The Collateral Trustee and the other Secured Parties
shall be accountable only for amounts actually received as a result of the
exercise of the powers granted to them herein, and neither they nor their
officers, directors, employees or agents shall be responsible to any Subsidiary
Pledgor for any act or failure to act hereunder, except to the extent determined
by a court of competent jurisdiction by a final non-appealable judgment to have
resulted from their own gross negligence or wilful misconduct.

         SECTION 11. Waivers; Amendment. (a) No failure or delay of the
Collateral Trustee, the Administrative Agent, any Issuing Bank, any Lender, the
AWNA Trustee, the BFI Trustee or the 2001 Indenture Trustee in exercising any
power or right hereunder or under any other Loan Document, the BFI Indenture,
the AWNA Indenture or any 2001 Indenture shall operate as a waiver thereof, nor
shall any single or partial exercise of any such right or power, or any
abandonment or discontinuance of steps to enforce such a right or power,
preclude any other or further exercise thereof or the exercise of any other
right or power. The rights and remedies of the Collateral Trustee hereunder and
of the other Secured Parties under the other Loan Documents, the BFI Indenture,
the AWNA Indenture and the 2001 Indentures are cumulative and are not exclusive
of any rights or remedies that they would otherwise have. No waiver of any
provisions of this Agreement or any other Loan Document, the BFI Indenture, the
AWNA Indenture or any 2001 Indenture or consent to any departure by any
Subsidiary Pledgor therefrom shall in any event be effective unless the same
shall be permitted by paragraph (b) below, and then such waiver or consent shall
be effective only in the specific instance and for the purpose for which given.
Without limiting the generality of the foregoing, the making of a Loan or
issuance of a Letter of Credit under the Credit Agreement shall not be construed
as a waiver of any Default under the Credit Agreement. No notice or demand on
any Subsidiary Pledgor or any other Loan Party in any case shall entitle such
Subsidiary Pledgor or any other Loan Party to any other or further notice or
demand in similar or other circumstances.

         (b) Neither this Agreement nor any provision hereof may be waived,
amended or modified except pursuant to a written agreement entered into between
the Collateral Trustee and the Subsidiary Pledgor or Subsidiary Pledgors with
respect to which such

<PAGE>

                                                                              14

waiver, amendment or modification is to apply, subject to any consent required
in accordance with Section 9.02 of the Credit Agreement.

         SECTION 12. Securities Act, etc. In view of the position of the
Subsidiary Pledgors in relation to the Pledged Securities, or because of other
current or future circumstances, a question may arise under the Securities Act
of 1933, as now or hereafter in effect, or any similar statute hereafter enacted
analogous in purpose or effect (such Act and any such similar statute as from
time to time in effect being collectively referred to herein as the "Federal
Securities Laws") with respect to any disposition of the Pledged Securities
permitted hereunder. Each Subsidiary Pledgor understands that compliance with
the Federal Securities Laws might very strictly limit the course of conduct of
the Collateral Trustee if the Collateral Trustee were to attempt to dispose of
all or any part of the Pledged Securities, and might also limit the extent to
which or the manner in which any subsequent transferee of any Pledged Securities
could dispose of the same. Similarly, there may be other legal restrictions or
limitations affecting the Collateral Trustee in any attempt to dispose of all or
part of the Pledged Securities under applicable Blue Sky or other state
securities laws or similar laws analogous in purpose or effect. Each Subsidiary
Pledgor recognizes that in light of such restrictions and limitations the
Collateral Trustee may, with respect to any sale of the Pledged Securities,
limit the purchasers to those who will agree, among other things, to acquire
such Pledged Securities for their own account, for investment, and not with a
view to the distribution or resale thereof. Each Subsidiary Pledgor acknowledges
and agrees that in light of such restrictions and limitations, the Collateral
Trustee, in its sole and absolute discretion, (a) may proceed to make such a
sale whether or not a registration statement for the purpose of registering such
Pledged Securities or part thereof shall have been filed under the Federal
Securities Laws and (b) may approach and negotiate with a single potential
purchaser to effect such sale. Each Subsidiary Pledgor acknowledges and agrees
that any such sale might result in prices and other terms less favorable to the
seller than if such sale were a public sale without such restrictions. In the
event of any such sale, the Collateral Trustee shall incur no responsibility or
liability for selling all or any part of the Pledged Securities at a price that
the Collateral Trustee, in its sole and absolute discretion, may in good faith
deem reasonable under the circumstances, notwithstanding the possibility that a
substantially higher price might have been realized if the sale were deferred
until after registration as aforesaid or if more than a single purchaser were
approached. The provisions of this Section 12 will apply notwithstanding the
existence of a public or private market upon which the quotations or sales
prices may exceed substantially the price at which the Collateral Trustee sells.

         SECTION 13. Registration, etc. Each Subsidiary Pledgor agrees that,
upon the occurrence and during the continuance of an Event of Default, if for
any reason the Collateral Trustee desires to sell any of the Pledged Securities
at a public sale, it will, at any time and from time to time, upon the written
request of the Collateral Trustee, use its best efforts to take or to cause the
issuer of such Pledged Securities to take such action and prepare, distribute
and/or file such documents, as are required or advisable in the reasonable
opinion of counsel for the Collateral Trustee to permit the public sale of such
Pledged Securities. Each Subsidiary Pledgor further agrees to indemnify, defend
and hold harmless the Collateral Trustee, each other Secured Party, any
underwriter and their

<PAGE>

                                                                              15

respective officers, directors, affiliates and controlling persons from and
against all losses, liabilities, expenses, costs of counsel (including, without
limitation, reasonable fees and expenses to the Collateral Trustee of a single
counsel in New York and such other local and special counsel as may be
reasonably necessary in connection therewith), and claims (including the costs
of investigation) that they may incur insofar as such loss, liability, expense
or claim arises out of or is based upon any alleged untrue statement of a
material fact contained in any prospectus (or any amendment or supplement
thereto) or in any notification or offering circular, or arises out of or is
based upon any alleged omission to state a material fact required to be stated
therein or necessary to make the statements in any thereof not misleading,
except insofar as the same may have been caused by any untrue statement or
omission based upon information furnished in writing to such Subsidiary Pledgor
or the issuer of such Pledged Securities by the Collateral Trustee or any other
Secured Party expressly for use therein. Each Subsidiary Pledgor further agrees,
upon such written request referred to above, to use its best efforts to qualify,
file or register, or cause the issuer of such Pledged Securities to qualify,
file or register, any of the Pledged Securities under the Blue Sky or other
securities laws of such states as may be requested by the Collateral Trustee and
keep effective, or cause to be kept effective, all such qualifications, filings
or registrations. Each Subsidiary Pledgor will bear all costs and expenses of
carrying out its obligations under this Section 13. Each Subsidiary Pledgor
acknowledges that there is no adequate remedy at law for failure by it to comply
with the provisions of this Section 13 and that such failure would not be
adequately compensable in damages, and therefore agrees that its agreements
contained in this Section 13 may be specifically enforced.

         SECTION 14. Security Interest Absolute. All rights of the Collateral
Trustee hereunder, the grant of a security interest in the Collateral and all
obligations of each Subsidiary Pledgor hereunder, shall be absolute and
unconditional irrespective of (a) any lack of validity or enforceability of the
Credit Agreement, any other Loan Document, the BFI Indenture, the AWNA
Indenture, any 2001 Indenture, any agreement with respect to any of the
Obligations or any other agreement or instrument relating to any of the
foregoing, (b) any change in the time, manner or place of payment of, or in any
other term of, all or any of the Obligations, or any other amendment or waiver
of or any consent to any departure from the Credit Agreement, the BFI Indenture,
the AWNA Indenture, any 2001 Indenture, any other Loan Document or any other
agreement or instrument relating to any of the foregoing, (c) any exchange,
release or nonperfection of any other collateral, or any release or amendment or
waiver of or consent to or departure from any guaranty, for all or any of the
Obligations or (d) any other circumstance that might otherwise constitute a
defense available to, or a discharge of, any Subsidiary Pledgor in respect of
the Obligations or in respect of this Agreement (other than the indefeasible
payment in full of all the monetary Obligations).

         SECTION 15. Termination or Release. This Agreement and the pledge
hereunder (i) shall cease to be effective with respect to the BFI Senior Note
Obligations and the AWNA Senior Note Obligations on the earlier of the date (a)
on which all the AWNA Indenture Debt and the BFI Indenture Debt shall have been
paid in full to the holders thereof and (b) that is ten days after the
provisions of the AWNA Indenture, the BFI Indenture and each 2001 Indenture that
require equal and ratable security shall be held by

<PAGE>

                                                                              16

a court of competent jurisdiction to be invalid, void or unenforceable and (ii)
shall terminate when all the monetary Credit Agreement Obligations have been
indefeasibly paid in full, the Lenders have no further commitment to lend, the
LC Exposure has been reduced to zero, the Issuing Banks have no further
commitment to issue Letters of Credit under the Credit Agreement and the Agent
has given written notification thereof to the Collateral Trustee, at which time
the Collateral Trustee shall execute and deliver to the Subsidiary Pledgors, at
the Subsidiary Pledgors' expense, all documents which the Subsidiary Pledgors
shall reasonably request to evidence such termination. Any execution and
delivery of such documents pursuant to this Section 15 shall be without recourse
to or warranty by the Collateral Trustee and shall, upon the reasonable prior
request of the Subsidiary Pledgors, be made prior to such termination for
holding in escrow pending such termination. A Subsidiary Pledgor shall
automatically be released from its obligations hereunder and the pledge of the
Collateral of such Subsidiary Pledgor hereunder shall be automatically released
in the event that all the Equity Interests of such Subsidiary Pledgor shall be
sold, transferred or otherwise disposed of to a Person that is not an Affiliate
of AWNA in accordance with the terms of the Credit Agreement and the other Loan
Documents; provided that, if required by the terms of the Credit Agreement, the
Required Lenders or all the Lenders, as the case may be, shall have consented to
such sale, transfer or other disposition and the terms of such consent did not
provide otherwise; and, provided, further, that any release of a Subsidiary
Pledgor or any Collateral after the occurrence and during the continuance of a
Triggering Event (as defined in the Collateral Trust Agreement) shall be subject
to the prior approval of the Collateral Trustee. The Pledge hereunder shall
automatically terminate with respect to any Collateral sold, transferred or
disposed of in accordance with this Agreement and the Credit Agreement, and the
Collateral Agent shall execute and deliver to the Pledgors, at the Pledgors'
expense, all documents which the Pledgors shall reasonably request to evidence
such termination (which documents shall, upon prior request of the Pledgors, be
delivered prior to, and held in escrow pending, such sale, transfer or
disposition).

         SECTION 16. Notices. All communications and notices hereunder shall be
in writing and given as provided in Section 9.01 of the Credit Agreement. All
communications and notices hereunder to any Subsidiary Pledgor shall be given to
it in care of AWNA. All notices and other communications given to any party
hereto in accordance with the provisions of this Agreement shall be deemed to
have been given on the date of receipt. Notices to the AWNA Indenture Trustee,
the BFI Indenture Trustee and the 2001 Indenture Trustee shall be given as
provided in the AWNA Indenture, the BFI Indenture and the 2001 Indenture,
respectively.

         SECTION 17. Further Assurances. Each Subsidiary Pledgor agrees to do
such further acts and things, and to execute and deliver such additional
conveyances, assignments, agreements and instruments, as the Collateral Trustee
may at any time reasonably request in connection with the administration and
enforcement of this Agreement or with respect to the Collateral or any part
thereof or in order better to assure and confirm unto the Collateral Trustee its
rights and remedies hereunder.

         SECTION 18. Binding Effect; Several Agreement; Assignments; Successor
Collateral Trustee. Whenever in this Agreement any of the parties hereto is
referred to,

such reference shall be deemed to include the successors and assigns of such
party; and all covenants, promises and agreements by or on behalf of any
Subsidiary Pledgor that are contained in this Agreement shall bind and inure to
the benefit of its successors and assigns. This Agreement shall become effective
on the Restatement Effective Date, and thereafter shall be binding upon the
Subsidiary Pledgors and the Collateral Trustee and their successors and assigns,
and shall inure to the benefit of each Subsidiary Pledgor, the Collateral
Trustee and the other Secured Parties, and their successors and assigns, except
that no Subsidiary Pledgor shall have the right to assign its rights hereunder
or any interest herein or in the Collateral (and any such attempted assignment
shall be void), except as expressly contemplated by this Agreement or the other
Loan Documents. This Agreement shall be construed as a separate agreement with
respect to each Subsidiary Pledgor and may be amended, modified, supplemented,
waived or released with respect to any Subsidiary Pledgor without the approval
of any other Subsidiary Pledgor and without affecting the obligations of any
other Subsidiary Pledgor hereunder. The Collateral Trustee may resign and a
successor collateral trustee may be appointed in the manner provided in the
Collateral Trust Agreement. Upon the acceptance of any appointment as a
collateral trustee by a successor collateral trustee, that successor collateral
trustee shall thereupon succeed to and become vested with all the rights,
powers, privileges and duties of the retiring collateral trustee, as secured
party under this Agreement, and the retiring collateral trustee shall thereupon
be discharged from its duties and obligations under this Agreement. After any
retiring collateral trustee's resignation, the provisions of this Agreement
shall inure to its benefit as to any actions taken or omitted to be taken by it
under this Agreement while it was Collateral Trustee.

         SECTION 19. Survival of Agreement; Severability. (a) All covenants,
agreements, representations and warranties made by each Subsidiary Pledgor
herein and in the other Loan Documents and in the certificates or other
instruments prepared or delivered in connection with or pursuant to this
Agreement or any other Loan Document shall be considered to have been relied
upon by the Collateral Trustee and the other Secured Parties and shall survive
the making by the Lenders of the Loans and the issuance of the Letters of Credit
by the Issuing Banks, regardless of any investigation made by any Secured Party
or on its behalf, and shall continue in full force and effect until this
Agreement has been terminated in accordance with Section 15.

         (b) In the event any one or more of the provisions contained in this
Agreement should be held invalid, illegal or unenforceable in any respect, the
validity, legality and enforceability of the remaining provisions contained
herein shall not in any way be affected or impaired thereby (it being understood
that the invalidity of a particular provision in a particular jurisdiction shall
not in and of itself affect the validity of such provision in any other
jurisdiction). The parties hereto shall endeavor in good-faith negotiations to
replace the invalid, illegal or unenforceable provisions with valid provisions
the economic effect of which comes as close as possible to that of the invalid,
illegal or unenforceable provisions.

         SECTION 20. GOVERNING LAW. THIS AGREEMENT SHALL BE GOVERNED BY, AND
CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.

         SECTION 21. Counterparts. This Agreement may be executed in two or more
counterparts, each of which shall constitute an original, but all of which, when
taken together, shall constitute a single contract (subject to Section 18), and
shall become effective as provided in Section 18. Delivery of an executed
counterpart of a signature page to this Agreement by facsimile transmission
shall be as effective as delivery of a manually executed counterpart of this
Agreement.

         SECTION 22. Rules of Interpretation. The rules of interpretation
specified in Section 1.03 of the Credit Agreement shall be applicable to this
Agreement. Section headings used herein are for convenience of reference only,

         SECTION 23. Jurisdiction; Consent to Service of Process. (a) Each
Subsidiary Pledgor hereby irrevocably and unconditionally submits, for itself
and its property, to the nonexclusive jurisdiction of any New York State court
or Federal court of the United States of America sitting in New York City, and
any appellate court from any thereof, in any action or proceeding arising out of
or relating to this Agreement or any other Loan Document, or for recognition or
enforcement of any judgment, and each of the parties hereto hereby irrevocably
and unconditionally agrees that, to the extent permitted by applicable law, all
claims in respect of any such action or proceeding may be heard and determined
in such New York State or, to the extent permitted by law, in such Federal
court. Each of the parties hereto agrees that a final judgment in any such
action or proceeding shall be conclusive and may be enforced in other
jurisdictions by suit on the judgment or in any other manner provided by law.
Nothing in this Agreement or any other Loan Document shall affect any right that
the Collateral Trustee or any other Secured Party may otherwise have to bring
any action or proceeding relating to this Agreement, any other Loan Document,
the BFI Indenture, the AWNA Indenture or any 2001 Indenture against any
Subsidiary Pledgor or its properties in the courts of any jurisdiction.

         (b) Each Subsidiary Pledgor hereby irrevocably and unconditionally
waives, to the fullest extent it may legally and effectively do so, any
objection that it may now or hereafter have to the laying of venue of any suit,
action or proceeding arising out of or relating to this Agreement or any other
Loan Document in any New York State or Federal court. Each of the parties hereto
hereby irrevocably waives, to the fullest extent permitted by law, the defense
of an inconvenient forum to the maintenance of such action or proceeding in any
such court.

         (c) Each party to this Agreement irrevocably consents to service of
process in the manner provided for notices in Section 16. Nothing in this
Agreement will affect the right of any party to this Agreement to serve process
in any other manner permitted by law.

         SECTION 24. WAIVER OF JURY TRIAL. EACH PARTY HERETO HEREBY WAIVES, TO
THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL
BY JURY IN RESPECT OF ANY

                                                                              19

LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF, UNDER OR IN CONNECTION WITH
THIS AGREEMENT, ANY OTHER LOAN DOCUMENT, THE BFI INDENTURE, THE AWNA INDENTURE
OR THE 2001 INDENTURE . EACH PARTY HERETO (A) CERTIFIES THAT NO REPRESENTATIVE,
AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE,
THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE
FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE
BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL
WAIVERS AND CERTIFICATIONS IN THIS SECTION.

         SECTION 25. Additional Subsidiary Pledgors. Pursuant to Section 5.10(b)
of the Credit Agreement, each Specified Subsidiary that is a subsidiary of BFI
that was not in existence or not a such a Specified Subsidiary on the
Restatement Effective Date is required to enter in this Agreement as a
Subsidiary Pledgor upon becoming such a Specified Subsidiary if such Subsidiary
owns or possesses property of a type that would be considered Collateral
hereunder. Upon execution and delivery by the Collateral Trustee and a
Subsidiary of an instrument in the form of Annex 1 hereto, such Subsidiary shall
become a Subsidiary Pledgor hereunder with the same force and effect as if
originally named as a Subsidiary Pledgor herein. The execution and delivery of
such instrument shall not require the consent of any Subsidiary Pledgor
hereunder. The rights and obligations of each Subsidiary Pledgor hereunder shall
remain in full force and effect notwithstanding the addition of any new
Subsidiary Pledgor as a party to this Agreement.

         SECTION 26. Collateral Trustee in its Individual Capacity. The
Collateral Trustee and its affiliates may make loans to, accept deposits from
and generally engage in any kind of business with Allied Waste and its
Subsidiaries as though the Collateral Trustee were not collateral trustee
hereunder. With respect to the Loans made by it and all Obligations owing to it,
the Collateral Trustee shall have the same rights and powers under this
Agreement as any Lender and may exercise the same as though it were not the
collateral trustee, and the terms "Lender" and "Lenders" shall include the
Collateral Trustee in its individual capacity.

                           "Supplement"), to the SHARED COLLATERAL PLEDGE
                           AGREEMENT dated as of July 30, 1999 and amended and
                           restated as of April 29, 2003 (as amended,
                           supplemented or otherwise modified from time to time,
                           the "Shared Collateral Pledge Agreement") among
                           Allied Waste North America, Inc., a Delaware
                           corporation ("AWNA"), each Subsidiary listed on
                           Schedule I thereto and each Subsidiary becoming a
                           party thereto as provided in Section 25 thereof (each
                           such Subsidiary individually, a "Subsidiary Pledgor",
                           and collectively, the "Subsidiary Pledgors"), and
                           JPMorgan Chase Bank, a New York banking corporation
                           ("JPMCB"), as collateral trustee (in such capacity,
                           the "Collateral Trustee") for the Secured Parties (as
                           defined in the Shared Collateral Pledge Agreement
                           referred to below).

         A. Reference is made to (a) the Credit Agreement dated as of July 21,
1999 and amended and restated as of April 29, 2003 (as amended, supplemented or
otherwise modified from time to time, the "Credit Agreement"), among AWNA,
Allied Waste Industries, Inc., the lenders from time to time party thereto (the
"Lenders"), and JPMCB, as administrative agent and collateral agent for the
Lenders.

         B. Capitalized terms used herein and not otherwise defined herein shall
have the meanings assigned to such terms in the Shared Collateral Pledge
Agreement and the Credit Agreement.

         C. The Subsidiary Pledgors have entered into the Shared Collateral
Pledge Agreement in order to induce the Lenders to make Loans and other
extensions of credit under the Credit Agreement. Section 5.10(b) of the Credit
Agreement provides that additional Specified Subsidiaries of AWNA shall become
Subsidiary Pledgors under the Shared Collateral Pledge Agreement by execution
and delivery of an instrument in the form of this Supplement. The undersigned
Subsidiary (the "New Subsidiary Pledgor") is executing this Supplement in
accordance with the requirements of the Credit Agreement to become a Subsidiary
Pledgor under the Shared Collateral Pledge Agreement in order to induce the
Lenders to make additional Loans and other extensions of credit under the Credit
Agreement.

         Accordingly, the Collateral Trustee and the New Subsidiary Pledgor
agree as follows:

         SECTION 1. In accordance with Section 25 of the Shared Collateral
Pledge Agreement, the New Subsidiary Pledgor by its signature below becomes a
Subsidiary Pledgor under the Shared Collateral Pledge Agreement with the same
force and effect as if originally named therein as a Subsidiary Pledgor and the
New Subsidiary Pledgor hereby agrees (a) to all the terms and provisions of the
Shared Collateral Pledge Agreement applicable to it as a Subsidiary Pledgor
thereunder and (b) represents and warrants that the representations and
warranties made by it as a Subsidiary Pledgor

<PAGE>

                                                                               2

thereunder are true and correct in all material respects on and as of the date
hereof. In furtherance of the foregoing, the New Subsidiary Pledgor, as security
for the payment and performance in full of the Obligations (as defined in the
Shared Collateral Pledge Agreement), does hereby create and grant to the
Collateral Trustee, its successors and assigns, for the benefit of the Secured
Parties, their successors and assigns, a security interest in and lien on all of
the New Subsidiary Pledgor's right, title and interest in and to the Collateral
(as defined in the Shared Collateral Pledge Agreement) of the New Subsidiary
Pledgor. Each reference to "Subsidiary Pledgor" in the Shared Collateral Pledge
Agreement shall be deemed, if applicable, to include the New Subsidiary Pledgor.
The Shared Collateral Pledge Agreement is hereby incorporated herein by
reference.

         SECTION 2. The New Subsidiary Pledgor represents and warrants to the
Collateral Trustee and the other Secured Parties that this Supplement has been
duly authorized, executed and delivered by it and constitutes its legal, valid
and binding obligation, enforceable against it in accordance with its terms.

         SECTION 3. This Supplement may be executed in counterparts, each of
which shall constitute an original, but all of which when taken together shall
constitute a single contract. This Supplement shall become effective when the
Collateral Trustee shall have received counterparts of this Supplement that,
when taken together, bear the signatures of the New Subsidiary Pledgor and the
Collateral Trustee. Delivery of an executed signature page to this Supplement by
facsimile transmission shall be as effective as delivery of a manually signed
counterpart of this Supplement.

         SECTION 4. The New Subsidiary Pledgor hereby represents and warrants
that set forth on Schedule I attached hereto is a true and correct schedule of
all its Pledged Securities.

         SECTION 5. Except as expressly supplemented hereby, the Shared
Collateral Pledge Agreement shall remain in full force and effect.

         SECTION 6. THIS SUPPLEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN
ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.

         SECTION 7. In case any one or more of the provisions contained in this
Supplement should be held invalid, illegal or unenforceable in any respect,
neither party hereto shall be required to comply with such provision for so long
as such provision is held to be invalid, illegal or unenforceable, but the
validity, legality and enforceability of the remaining provisions contained
herein and in the Shared Collateral Pledge Agreement shall not in any way be
affected or impaired. The parties hereto shall endeavor in good-faith
negotiations to replace the invalid, illegal or unenforceable provisions with
valid provisions the economic effect of which comes as close as possible to that
of the invalid, illegal or unenforceable provisions.

         SECTION 8. All communications and notices hereunder shall be in writing
and given as provided in Section 9.01 of the Credit Agreement. All
communications and

notices hereunder to the New Subsidiary Pledgor shall be given to it in care of
AWNA as set forth in the Shared Collateral Pledge Agreement.

         SECTION 9. The New Subsidiary Pledgor agrees to reimburse (or cause to

in connection with this Supplement, including the reasonable fees, other charges

Trustee have duly executed this Supplement to the Shared Collateral Pledge
Agreement as of the day and year first above written.
