         consideration at the time of such disposition at least equal to the
         fair market value of the shares or the assets disposed of, as
         determined in good faith by the Board of Directors for any transaction
         (or series of transactions) involving in excess of $10 million and not

         liabilities reflected on the consolidated balance sheet of the Company
         and its Restricted Subsidiaries in accordance with generally accepted
         accounting principles (excluding Debt or any other liabilities
         subordinate in right of payment to the Notes) and release from all
         liability on such Debt or other liabilities assumed, (C) assets used
         in, or stock or other ownership interests in a Person that upon the
         consummation of such Asset Disposition becomes a Restricted Subsidiary
         and will be principally engaged in, the business of the Company or any
         of its Restricted Subsidiaries as such business is conducted
         immediately prior to such Asset Disposition, (D) any securities, notes
         or other obligations received by the Company or any such Restricted
         Subsidiary from such transferee that are contemporaneously (subject to
         ordinary settlement periods) converted by the Company or such
         Restricted Subsidiary into cash or Cash Equivalents (to the extent of
         cash and Cash Equivalents received), (E) any Designated Noncash
         Consideration received pursuant to this clause (E) that is at the time
         outstanding, not to exceed 15% of Consolidated Total Assets at the time
         of the receipt of such Designated Noncash Consideration (with the fair
         market value of each item of Designated Noncash Consideration being
         measured at the time received and without giving effect to subsequent
         changes in value), or (F) any combination thereof; and (iii) 100% of
         the Net Available Proceeds from such Asset Disposition (including from
         the sale of any marketable cash equivalents received therein) are

         first, within one year from the later of the date of such Asset
         Disposition or the receipt of such Net Available Proceeds, to repayment
         of Debt of the Company or its Restricted Subsidiaries then outstanding
         under the Credit Facility which would require such application or which
         would prohibit payments pursuant to clause (B); (B) second, to the
         extent Net Available Proceeds are not required to be applied as
         specified in clause (A), to purchases of outstanding Notes and other
         Debt of the Company that ranks pari passu in right of payment to the
         Notes (on a pro rata basis based upon the outstanding aggregate
         principal amount thereof) pursuant to an Offer to Purchase (to the
         extent such an offer is not prohibited by the terms of the Credit
         Facility then in effect) at a purchase price equal to 100% of the
         principal amount thereof plus accrued interest to the date of purchase
         (subject to the rights of Holders of record on the relevant Regular
         Record Date to receive interest due on an Interest Payment Date that is
         on or prior to the purchase date); and (C) third, to the extent of any
         remaining Net Available Proceeds following completion of such Offer to
         Purchase, to any other use as determined by the Company which is not
         otherwise prohibited by this Eleventh Supplemental Indenture and
         provided further that the 75% limitation referred to in clause (ii)
         above shall not apply to any Asset Disposition if the consideration
         received therefrom, as determined in good faith by the Company's Board
         of Directors, is equal to or greater than what the after-tax proceeds
         would have been had the Asset Disposition complied with the
         aforementioned 75% limitation.

                  Notwithstanding the foregoing, the Company shall not be
         required to comply with the provisions described in clause (iii) of the
         preceding paragraph: (i) if the Net Available Proceeds ("REINVESTED
         AMOUNTS") are invested or committed to be invested within one year from
         the later of the date of the related Asset Disposition or the receipt
         of such Net Available Proceeds in assets that will be used in the
         business of the Company or any of its Restricted Subsidiaries as such
         business is conducted prior to such Asset Disposition (determined by
         the Board of Directors in good faith) or (ii) to the extent the Company
         elects to redeem the Notes with the Net Available Proceeds pursuant to
         any of the provisions of subsection (5) of this Section 1.01.

                  Notwithstanding the foregoing, the Company shall not be
         required to comply with the requirements described in clause (ii) of
         the second preceding paragraph if the Asset Disposition is an Excepted
         Disposition.

                  Any Offer to Purchase pursuant to this subsection 12(a) shall
         be effected by the sending of the written terms and conditions thereof
         (the "OFFER DOCUMENT") by the Company, by first class mail, to Holders
         of the Notes within 30 days after the date which is one year after the
         later of the date of consummation of the Asset Disposition referred to
         in this subsection 12(a) or the receipt of the Net Available Proceeds
         from such Asset Disposition. The aggregate principal amount of the
         Notes to be offered to be purchased pursuant to the Offer to Purchase
         shall equal the Net Available Proceeds required to be made available
         therefor pursuant to clause (iii)(B) of this subsection 12(a) (rounded
         down to the next lowest integral multiple of $1,000). Each Holder shall
         be entitled to tender all or any portion of the Notes owned by such
         Holder pursuant to the Offer to Purchase, subject to the requirement
         that any portion of a Note tendered must be tendered in an integral
         multiple of $1,000 principal amount.

         outstanding Notes, at a purchase price equal to 101% of their aggregate
         principal amount plus accrued interest, if any, to the date of purchase
         (subject to the rights of Holders of record on the relevant Regular
         Record Date to receive interest due on an Interest Payment Date that is
         on or prior to the date of purchase).

                  A "CHANGE OF CONTROL" shall be deemed to have occurred in the
         event that, after the date of this Eleventh Supplemental Indenture,

                  (i) so long as the Company is a Subsidiary of Allied: (a) any
         Person, or any Persons (other than a Permitted Allied Successor),

         together with any Affiliates or Related Persons thereof (other than any
         employee stock ownership plan), beneficially own 50% or more of the
         total voting power of all classes of Voting Stock of Allied, (b) any
         Person or Allied Group, together with any Affiliates or Related Persons
         thereof, succeeds in having a sufficient number of its nominees who

         of Directors of Allied such that such nominees, when added to any
         existing director remaining on the Board of Directors of Allied after
         such election who is an Affiliate or Related Person of such Person or
         Allied Group, shall constitute a majority of the Board of Directors of
         Allied, or (c) there

<PAGE>
         occurs any transaction or series of related transactions other than a
         merger, consolidation or other transaction with a Related Business in
         which the shareholders of Allied immediately prior to such transaction
         (or series) receive (I) solely Voting Stock of Allied (or its successor
         or parent, as the case may be), (II) cash, securities and other
         property in an amount which could be paid by the Company as a

         which another entity becomes a successor to, or parent of, Allied, of
         the successor or parent entity), and

                  (ii) if the Company is not a Subsidiary of Allied: (a) any
         Person, or any Persons (other than a Permitted Allied Successor),
         acting together that would constitute a Group for purposes of Section
         13(d) of the Exchange Act (an "AWNA GROUP"), together with any
         Affiliates or Related Persons thereof (other than any employee stock
         ownership plan) beneficially own 50% or more of the total voting power
         of all classes of Voting Stock of the Company, (b) any Person or AWNA
         Group, together with any Affiliates or Related Persons thereof,
         succeeds in having a sufficient number of its nominees who have not
         been approved by the Continuing Directors elected to the Board of
         Directors of the Company such that such nominees, when added to any
         existing director remaining on the Board of Directors of the Company
         after such election who is an Affiliate or Related Person of such
         Person or AWNA Group, shall constitute a majority of the Board of
         Directors of the Company, or (c) there occurs any transaction or series
         of related transactions other than a merger, consolidation or other
         transaction with a Related Business in which the shareholders of the

         case may be), (II) cash, securities and other property in an amount
         which could be paid by the Company as a Restricted Payment under this

         investment grade credit rating from any other "nationally recognized
         statistical rating organization" (within the meaning of Rule

         issuance of the Notes that cease to be applicable after the Rating
         Event Date be reinstated.

                  The Company shall not incur any Debt and shall not permit
         Restricted Subsidiaries to Incur any Debt or issue Preferred Stock
         unless, immediately after giving effect to the Incurrence of such Debt
         or issuance of such Preferred Stock and the receipt and application of
         the proceeds thereof, the Consolidated EBITDA Coverage Ratio of the
         Company for the four full fiscal quarters next preceding the Incurrence
         of such Debt or issuance of such Preferred Stock, calculated on a pro
         forma basis if such Debt had been Incurred or such Preferred Stock had
         been issued and the proceeds thereof had been received and so applied
         at the beginning of the four full fiscal quarters, would be greater
         than 2.0 to 1.0.

                  Without regard to the foregoing limitations, the Company or
         any Restricted Subsidiary of the Company may Incur the following Debt:

                  Subsidiary or Debt owed by a Restricted Subsidiary to the

                  another Restricted Subsidiary, or (y) such Restricted
                  Subsidiary ceases to be a Restricted Subsidiary, the
                  provisions of this clause (iii) shall no longer be applicable
                  to such Debt and such Debt shall be deemed to have been
                  incurred at the time of such transfer or other disposition or
                  at the time such Restricted Subsidiary ceases to be a

                  superseded by subsection 13 of this Section 1.01 of this
                  Eleventh Supplemental Indenture), which Debt: (x) was issued
                  by a Person prior to the time such Person becomes a Restricted
                  Subsidiary in such transaction (including by way of merger or
                  consolidation with the Company or another Restricted

                  Debt does not exceed the principal amount of Debt so renewed,
                  extended, refinanced or refunded (plus the amount of any
                  premium and accrued interest, plus customary fees, consent
                  payments, expenses and costs relating to the Debt so renewed,

         Eleventh Supplemental Indenture; (b) the Credit Facility, including any

         encumbrance or restriction contained in such renewal, extension,
         refinancing or refunding agreement are no more restrictive in any
         material respect than the provisions contained in the agreement it
         replaces, as determined in good faith by the Board of Directors; or (h)
         such encumbrance or restriction is the result of applicable corporate
         law or regulation relating to the payment of dividends or

         resolution of the Board of Directors set forth in an Officers'
         Certificate certifying that such Affiliate Transaction complies with
         clause (a) above and that such Affiliate Transaction has been approved
         by a majority of the disinterested members of the Board of Directors,
         or (ii) an opinion as to the fairness to the Company or such Restricted
         Subsidiary, as the case may be, of such Affiliate Transaction from a
         financial point of view issued by an accounting, appraisal or
         investment banking firm of national standing.

                  Notwithstanding the foregoing, the following items shall not
         be deemed to be Affiliate Transactions: (a) customary directors' fees,
         indemnification or similar arrangements or any employment agreement or
         other compensation plan or arrangement entered into by the Company or
         any of its Restricted Subsidiaries in the ordinary course of business
         including ordinary course loans to employees not to exceed: (i) $5
         million outstanding in the aggregate at any time, and (ii) $2 million
         to any one employee and consistent with the past practice of the
         Company or such Restricted Subsidiary; (b) loans by the Company and its
         Restricted Subsidiaries to employees of Allied or any of its
         Subsidiaries in connection with management incentive plans not to
         exceed $25 million at any time outstanding; provided that such
         limitation shall not apply to loans the proceeds of which are used to
         purchase common stock of: (i) the Company from the Company, or (ii)
         Allied from Allied if and to the extent that Allied utilizes the
         proceeds thereof to acquire Capital Stock (other than Redeemable
         Interests) of the Company; (c) transactions between or among the
         Company and/or its Restricted Subsidiaries; (d) payments of customary
         fees by the Company or any of its Restricted Subsidiaries to investment
         banking firms and financial advisors made for any financial advisory,
         financing, underwriting or placement services or in respect of other
         investment banking activities, including, without limitation, in
         connection with acquisitions or divestitures which are approved by a
         majority of the Board of Directors in good faith; (e) any agreement as
         in effect on the date of this Eleventh Supplemental Indenture or any
         amendment thereto (so long as such amendment is not disadvantageous to
         the Holders of the Notes in any material respect) or any transaction
         contemplated thereby; and (f) Restricted Payments that are permitted by
         the provisions of subsection 12(e) of this Section 1.01 of this
         Eleventh Supplemental Indenture.

                  (i) Provision of Financial Information.

                  Whether or not Allied is required to be subject to Section
         13(a) or 15(d) of the Exchange Act, or any successor provision thereto,
         the Company (or Allied for so long as the Company is a Wholly-Owned
         Subsidiary of Allied) shall file with the Commission the annual
         reports, quarterly reports and other documents which the Company (or
         Allied for so long as the Company is a Wholly-Owned Subsidiary of
         Allied) would have been required to file with the Commission pursuant
         to such Section 13(a) or 15(d) or any successor provision thereto if
         the Company (or Allied for so long as the Company is a Wholly-Owned
         Subsidiary of Allied) were so required, such documents to be filed with
         the Commission on or prior to the respective dates (the "REQUIRED
         FILING DATES") by which the Company would have been required so to file
         such documents if the Company were so required. The Company shall also
         in any event: (a) within 15 days of each Required Filing Date file with
         the Trustee copies of the annual reports, quarterly reports and other
         documents which the Company (or Allied for so long as the Company is a
         Wholly-Owned Subsidiary of Allied) filed with the Commission pursuant
         to such Section 13(a) or 15(d) or any successor provisions thereto or
         would have been required to file with the Commission pursuant to such
         Section 13(a) or 15(d) or any successor provisions thereto if the
         Company

                                       12
<PAGE>
         (or Allied for so long as the Company is a Wholly-Owned Subsidiary of
         Allied) were required to comply with such Sections, and (b) if filing
         such documents by the Company (or Allied for so long as the Company is
         a Wholly-Owned Subsidiary of Allied) with the Commission is not
         permitted under the Exchange Act, promptly upon written request supply
         copies of such documents to any prospective Holder.

                  (j) Unrestricted Subsidiaries.

                  The Company at any time may designate any Person that is a
         Subsidiary, or after the date of this Eleventh Supplemental Indenture
         becomes a Subsidiary, of the Company as an "UNRESTRICTED SUBSIDIARY,"
         whereupon (and until such Person ceases to be an Unrestricted
         Subsidiary) such Person and each other Person that is then or
         thereafter becomes a Subsidiary of such Person shall be deemed to be an
         Unrestricted Subsidiary. In addition, the Company may at any time
         terminate the status of any Unrestricted Subsidiary as an Unrestricted
         Subsidiary, whereupon such Subsidiary and each other Subsidiary of the
         Company (if any) of which such Subsidiary is a Subsidiary shall be a
         Restricted Subsidiary.

                  Notwithstanding the foregoing, no change in the status of a
         Subsidiary of the Company from a Restricted Subsidiary to an
         Unrestricted Subsidiary or from an Unrestricted Subsidiary to a
         Restricted Subsidiary will be effective, and no Person may otherwise
         become a Restricted Subsidiary, if:

                           (i) in the case of any change in status of a
                  Restricted Subsidiary to an Unrestricted Subsidiary, the
                  Restricted Payment resulting from such change, would violate
                  the provisions of clause (3) of the first paragraph of
                  subsection 12(e) of this Section 1.01 of this Eleventh
                  Supplemental Indenture; or

                           (ii) such change or other event would otherwise
                  result (after the giving of notice or the lapse of time, or
                  both) in an Event of Default.

                  In addition and notwithstanding the foregoing, no Restricted
         Subsidiary of the Company may become an Unrestricted Subsidiary, and
         the status of any Unrestricted Subsidiary as an Unrestricted Subsidiary
         will be deemed to have been immediately terminated (whereupon such
         Subsidiary and each other Subsidiary of the Company (if any) of which
         such Subsidiary is a Subsidiary will be a Restricted Subsidiary) at any
         time when:

                           (i) such Subsidiary (A) has outstanding Debt that is
                  Unpermitted Debt (as defined below), or (B) owns or holds any
                  Capital Stock of or other ownership interests in, or a Lien on
                  any property or other assets of, the Company or any of its
                  Restricted Subsidiaries; or

                           (ii) the Company or any other Restricted Subsidiary
                  (A) provides credit support for, or a Guarantee of, any Debt
                  of such Subsidiary (including any undertaking, agreement or
                  instrument evidencing such Debt), or (B) is directly or
                  indirectly liable on any Debt of such Subsidiary. Any
                  termination of the status of an Unrestricted Subsidiary as an
                  Unrestricted Subsidiary pursuant to the preceding sentence
                  will be deemed to result in a breach of this covenant in any
                  circumstance in which the Company would not be permitted to
                  change the status of such Unrestricted Subsidiary to the
                  status of a Restricted Subsidiary pursuant to the preceding
                  paragraph.

                  "UNPERMITTED DEBT" means any Debt of a Subsidiary of the
                  Company if: (x) a default thereunder (or under any instrument
                  or agreement pursuant to or by which such Debt is issued,
                  secured or evidenced) or any right that the Holders thereof
                  may have to take enforcement action against such Subsidiary or
                  its property or other assets, would permit (whether or not
                  after the giving of notice or the lapse of time or both) the
                  Holders of any Debt of the Company or any other Restricted
                  Subsidiary to declare the same due and payable prior to the
                  date on which it otherwise would have become due and payable
                  or otherwise to take any enforcement action against the
                  Company or any such other Restricted Subsidiary, or (y) such
                  Debt is secured by a Lien on any property or other assets of
                  the Company and any of its other Restricted Subsidiaries.

                  Each Person that is or becomes a Subsidiary of the Company
                  shall be deemed to be a Restricted Subsidiary at all times
                  when it is a Subsidiary of the Company that is not an
                  Unrestricted Subsidiary. Each Person that is or becomes a
                  Wholly-Owned Subsidiary of the Company shall be deemed to be a
                  Wholly-Owned Restricted Subsidiary at all times when it is a
                  Wholly-Owned Subsidiary of the Company that is not an
                  Unrestricted Subsidiary.

         (13) Mergers, Consolidations and Certain Sales of Assets. Section 7.1
of the Indenture is hereby superseded by the following in respect of the Notes:

         "The Company (i) shall not consolidate with or merge into any Person;
(ii) shall not permit any Person other than a Restricted Subsidiary to
consolidate with or merge into the Company; and (iii) may not, directly or
indirectly, in one or a series of transactions, transfer, convey, sell, lease or
otherwise dispose of all or substantially all of the properties and assets of
the Company and its Subsidiaries on a consolidated basis; unless, in each case
of (i), (ii) and (iii) above:

                  (1) immediately before and after giving effect to such
         transaction (or series) and treating any Debt Incurred by the Company
         or a Subsidiary of the Company as a result of such transaction (or
         series) as having been incurred by the Company of such Subsidiary at
         the time of the transaction (or series), no Event of Default, or event
         that with the passing of time or the giving of notice, or both, will
         constitute an Event of Default, shall have occurred and be continuing;

                  (2) in a transaction (or series) in which the Company does not
         survive or in which the Company transfers, conveys, sells, leases or
         otherwise disposes of all or substantially all of its properties and
         assets, the successor entity is a corporation, partnership, limited
         liability company or trust and is organized and validly existing under
         the laws of the United States of America, any State thereof or the
         District of Columbia and expressly assumes, by a supplemental indenture
         executed and delivered to the Trustee in form satisfactory to the
         Trustee, all the Company's obligations under this Eleventh Supplemental
         Indenture;

                  (3) if such transaction (or series) occurs prior to the
         occurrence of a Rating Event Date, either (x) the Company or the
         successor entity would, at the time of such transaction (or series) and
         after giving pro forma effect thereto as if such transaction (or
         series) had occurred at the beginning of the most recently ended four
         full fiscal quarter period for which internal financial statements are
         available immediately preceding the date of such transaction (or
         series), have been permitted to Incur at least $1.00 of additional Debt
         pursuant to the Consolidated EBITDA Coverage Ratio test set forth in
         the first

                                       14
<PAGE>
         paragraph under subsection 12(d) of this Section 1.01, or (y) the
         Consolidated EBITDA Coverage Ratio of the Company or the successor
         entity for the most recently ended four full fiscal quarter period for
         which internal financial statements are available immediately preceding
         the date of such transaction (or series), calculated on a pro forma
         basis as if such transaction (or series) had occurred at the beginning
         of such four full fiscal quarter period, would be no less than such
         Consolidated EBITDA Coverage Ratio, calculated without giving effect to
         such transaction or series or any other transactions (or series) that
         is subject to the provisions of the Indenture described in this
         paragraph and that occurred after the date that is twelve months before
         the date of such transaction (or series);

                  (4) if, as a result of any such transaction, property or
         assets of the Company or any Restricted Subsidiary of the Company would
         become subject to a Lien prohibited by subsection 12(g) of this Section
         1.01, the Company or the successor entity shall have secured the Notes
         as required by such covenant; and

                  (5) the Company has delivered to the Trustee an Officers'
         Certificate and an Opinion of Counsel as specified in the Indenture.

                  The Company shall deliver to the Trustee prior to the proposed
         consolidation, merger, sale, transfer, lease or other disposition an
         Officers' Certificate to the foregoing effect and an Opinion of Counsel
         stating that the proposed consolidation, merger, sale, transfer, lease
         or other disposition and such supplemental indenture comply with the
         Indenture and that all conditions precedent to the consummation of such
         transaction under this Section 7.1 have been met."

         (14) Security.

         The Security Agreements shall secure the due and punctual payment of
the principal of and interest and Special Interest, if any, on the Notes when
and as the same shall be due and payable, whether on an interest payment date,
at maturity, by acceleration, repurchase, redemption or otherwise, and interest
on the overdue principal of and interest and Special Interest (to the extent
permitted by law), if any, on the Notes and performance of all other obligations
of the Company to the Holders of Notes or the Trustee under this Eleventh
Supplemental Indenture and the Notes, according to the terms hereunder or
thereunder. Each Holder of Notes, by its acceptance thereof, consents and agrees
to the terms of the Security Agreements (including, without limitation, the
provisions providing for foreclosure and release of the Collateral) as the same
may be in effect or may be amended from time to time in accordance with their
terms. The Company shall deliver to the Trustee copies of all documents
delivered to the collateral trustee pursuant to the Security Agreements, and
shall do or cause to be done all such acts and things as may be necessary or
proper, or as may be required by the provisions of the Security Agreements, to
assure and confirm to the Trustee and the collateral trustee the security
interest in the Collateral contemplated hereby, by the Security Agreements or
any part thereof, as from time to time constituted, so as to render the same
available for the security and benefit of this Eleventh Supplemental Indenture
and of the Notes secured hereby, according to the intent and purposes herein
expressed. The Company shall take, or shall cause its Subsidiaries to take, upon
request of the Trustee, any and all actions reasonably required to cause the
Security Agreements to create and maintain, as security for the obligations of
the Company under this Eleventh Supplemental Indenture and the Notes, a valid
and enforceable perfected first priority Lien in and on all the Collateral in
favor of the collateral trustee for the benefit of the Holders of Notes.

                  (a) Opinions and Certificates.


                                       15
<PAGE>
                           (i) The Company shall furnish to the Trustee all
         opinions and certificates delivered by the Company in connection with
         the Security Agreements and such opinions and certificates shall be for
         the benefit of the Trustee and the Holders of the Notes.

                           (ii) The Company shall otherwise comply with the
         provisions of TIA Section 314(b).

                  (b) Release of Collateral.

                           (i) Subject to this subsection 14(b) of this Section
         1.01 of this Eleventh Supplemental Indenture, the Collateral may be
         released from the Lien and security interest created by the Security
         Agreements at any time or from time to time in accordance with the
         provisions of the Security Agreements. The collateral trustee shall
         execute, deliver or acknowledge any necessary or proper instruments of
         termination, satisfaction or release to evidence the release of any
         Collateral permitted to be released pursuant to this Eleventh
         Supplemental Indenture or the Security Agreements.

                           (ii) The release of any Collateral from the terms of
         this Eleventh Supplemental Indenture and the Security Agreements shall
         not be deemed to impair the security under this Eleventh Supplemental
         Indenture in contravention of the provisions hereof if and to the
         extent the Collateral is released pursuant to the terms of the Security
         Agreements. To the extent applicable, the Company shall cause TIA
         Section 313(b), relating to reports, and TIA Section 314(d), relating
         to the release of property or securities from the Lien and security
         interest of the Security Agreements and relating to the substitution
         therefor of any property or securities to be subjected to the Lien and
         security interest of the Security Agreements, to be complied with. The
         Company shall furnish to the Trustee and the collateral trustee, prior
         to each proposed release of Collateral pursuant to the Security
         Agreements, (i) all documents required by TIA Section 314(d) and (ii)
         an Opinion of Counsel, which may be rendered by internal counsel to the
         Company, to the effect that such accompanying documents constitute all
         documents required by TIA Section 314(d).

                           (iii) Any certificate or opinion required by TIA
         Section 314(d) may be made by an Officer of the Company except in cases
         where TIA Section 314(d) requires that such certificate or opinion be
         made by an independent Person, which Person shall be an independent
         engineer, appraiser or other expert selected or approved by the Trustee
         and the collateral trustee in the exercise of reasonable care.

                           (iv) In the event that the Company wishes to obtain a
         release of any Collateral in accordance with the Security Agreements
         and has delivered the certificates and documents required by the
         Security Agreements and this subsection 14(b) of this Section 1.01 of
         this Eleventh Supplemental Indenture, the Trustee shall determine
         whether it has received all documentation required by TIA Section
         314(d) in connection with such release and, based on such determination
         and the Opinion of Counsel delivered pursuant to Section 10.03(b),
         shall deliver a certificate to the collateral trustee setting forth
         such determination. The Trustee may, to the extent permitted by the
         Indenture, accept as conclusive evidence of compliance with the
         foregoing provisions the appropriate statements contained in such
         documents and such Opinion of Counsel.

                  (c) Authorization of Actions to Be Taken by the Trustee Under
the Security Agreements. Subject to the provisions of the Indenture, the Trustee
may, in its sole discretion and without the consent of the Holders of Notes,
instruct, on behalf of the Holders of Notes, the collateral trustee to take all


                                       16
<PAGE>
actions it deems necessary or appropriate in order to (a) enforce the rights of
the Trustee and the Holders of Notes under any of the terms of the Security
Agreements and (b) collect and receive any and all amounts payable in respect of
the obligations of the Company under this Eleventh Supplemental Indenture and
the Notes, provided, that in no event shall the collateral trustee be required
to take any actions that violate the terms of the Security Agreements or the
Credit Facility. The Trustee shall have power to institute and maintain such
suits and proceedings as it may deem expedient to preserve or protect its
interests and the interests of the Trustee and the Holders of Notes in the
Collateral.

                  (d) Authorization of Receipt of Funds by the Trustee Under the
Security Agreements. The Trustee is authorized to receive any funds for the
benefit of the Holders of Notes distributed under the Security Agreements, and
to make further distributions of such funds to the Holders of Notes according to
the provisions of this Eleventh Supplemental Indenture.

                  (e) Termination of Security Interest. Upon (1) the full and
final payment and performance of all obligations of the Company under this
Eleventh Supplemental Indenture and the Notes; (2) the release of the Lien on
the Collateral securing the BFI Notes, the Allied NA Senior Notes and all other
indebtedness of Allied and its Restricted Subsidiaries (other than under the
Credit Facility); or (3) the sale of any such Collateral in accordance with the
applicable provisions of this Eleventh Supplemental Indenture, the Trustee
shall, at the request of the Company, deliver a certificate to the collateral
trustee instructing the collateral trustee to release the Liens (or in the case
of clause (3), the Liens on such Collateral) pursuant to this Eleventh
Supplemental Indenture and the Security Agreements.

                  (f) No Amendments to the Security Agreements. The Company
shall not amend, waive or modify any provisions of the Security Agreements if
such amendment, waiver or modification could reasonably be expected to adversely
impact the Holder of Notes without the consent of a majority of Holder of Notes.

                  (g) Maintenance. The Company shall maintain as security for
the obligations of the Company under this Eleventh Supplement Indenture and the
Notes, an equal and ratable sharing of the perfected security interest held by
the collateral trustee under the uniform commercial code as in effect in the
State of New York pursuant to the Security Agreements in the Collateral.

         (15) Events of Default. In addition to the Events of Default set forth
in Section 5.1 of the Indenture, the Notes shall include the following
additional Event of Default designated as clause (j) of such Section, which
shall be deemed an Event of Default under Section 5.1 of the Indenture:

                  "(j) failure to perform or comply with the provisions of
         Section 7.1 of the Indenture (as superseded by subsection 13 of Section
         1.01 hereof) or the provisions of subsection 12(a) or subsection 12(b)
         of Section 1.01 of this Eleventh Supplemental Indenture."

                  (b) In addition, Section 5.1 of the Indenture is further
         supplemented by adding the following paragraph thereto:

         "If an Event of Default occurs at any time by reason of any willful

         (a) Transfers of Interests in Global Notes for Definitive Notes. A
Global Note may not be transferred as a whole except by the Depositary to a
nominee of the Depositary, by a nominee of the Depositary to the Depositary or
to another nominee of the Depositary, or by the Depositary or any such nominee
to a successor Depositary or a nominee of such successor Depositary. All Global
Notes shall be exchanged by the Company for Definitive Notes if (i) the Company
delivers to the Trustee notice from the Depositary that it is unwilling or
unable to continue to act as Depositary or that it is no longer a clearing
agency registered under the Exchange Act and, in either case, a successor
Depositary is not appointed by the Company within 90 days after the date of such
notice from the Depositary, (ii) the Company in its sole discretion determines
that the Global Notes (in whole but not in part) should be exchanged for
Definitive Notes and delivers a written notice to such effect to the Trustee, or

Default under the Indenture with respect to the Notes. Upon the occurrence of

shall be issued in such names as the Participants and Indirect Participants and
the Depositary shall instruct the Trustee. Global Notes also may be exchanged or
replaced, in whole or in part, as provided in Sections 3.6 and 3.4 of the

of, a Global Note or any portion thereof, pursuant to this Section 2.02 or

another Note other than as provided in this Section 2.02(a), however, beneficial
interests in a Global Note may be transferred and exchanged as provided in
Section 2.02(b) or (c) of this Eleventh Supplemental Indenture.

         (b) Transfer and Exchange of Beneficial Interests in the Global Notes.
The transfer and exchange of beneficial interests in the Global Notes shall be
effected through the Depositary, in accordance with the provisions of this
Eleventh Supplemental Indenture and the Applicable Procedures. Beneficial
interests in the Restricted Global Notes shall be subject to restrictions on
transfer comparable to those set forth in this Eleventh Supplemental Indenture
to the extent required by the Securities Act. Transfers of beneficial interests
in the Global Notes also shall require compliance with either subparagraph (i)
or (ii) below, as applicable, as well as one or more of the other following
subparagraphs, as applicable:

                  (i) Transfer of Beneficial Interests in the Same Global Note.
         Beneficial interests in any Restricted Global Note may be transferred
         to Persons who take delivery thereof in the form of a beneficial
         interest in the same Restricted Global Note in accordance with the
         transfer restrictions set forth in the Private Placement Legend;
         provided, however, that prior to the expiration of the Restricted
         Period, transfers of beneficial interests in the Regulation S Global
         Note may not be made to a U.S. Person or for the account or benefit of
         a U.S. Person (other than an Initial Purchaser.) Beneficial interests
         in any Unrestricted Global Note may be transferred to Persons who take
         delivery thereof in the form of a beneficial interest in an
         Unrestricted Global Note. No written orders or instructions shall be
         required to be delivered to the Registrar to effect the transfers
         described in this Section 2.02(b)(i).

                  (ii) All Other Transfers and Exchanges of Beneficial Interests
         in Global Notes. In connection with all transfers and exchanges of
         beneficial interests that are not subject to Section 2.02(b)(i) above,
         the transferor of such beneficial interest must deliver to the
         Registrar either (A)(1) a written order from a Participant or an
         Indirect Participant given to the Depositary in accordance with the
         Applicable Procedures directing the Depositary to credit or cause to be
         credited a beneficial interest in another Global Note in an amount
         equal to the beneficial interest to be transferred or exchanged and (2)
         instructions given in accordance with the Applicable Procedures
         containing information regarding the Participant account to be credited
         with such increase or (B)(1) a written order from a Participant or an
         Indirect Participant given to the Depositary in accordance with the
         Applicable Procedures directing the Depositary to cause to be issued a
         Definitive Note in an amount equal to the beneficial interest to be
         transferred or exchanged and (2) instructions given by the Depositary
         to the Registrar containing information regarding the Person in whose
         name such Definitive Note shall be registered to effect the transfer or
         exchange referred to in (1) above. Upon consummation of an Exchange
         Offer by the Company in accordance with Section 2.02(f) of this
         Eleventh Supplemental Indenture, the requirements of this Section
         2.02(b)(ii) shall be deemed to have been satisfied upon receipt by the
         Registrar of the instructions contained in the Letter of Transmittal
         delivered by the Holder of such beneficial interests in the Restricted
         Global Notes. Upon satisfaction of all of the requirements for transfer
         or exchange of beneficial interests in Global Notes contained in this
         Eleventh Supplemental Indenture and the Notes or otherwise applicable
         under the Securities Act, the Trustee shall adjust the principal amount
         of the relevant Global Note(s) pursuant to Section 2.02(h) of this
         Eleventh Supplemental Indenture.

                  (iii) Transfer of Beneficial Interests to Another Restricted
         Global Note. A beneficial interest in any Restricted Global Note may be
         transferred to a Person who takes delivery thereof in the form of a
         beneficial interest in another Restricted Global Note if the transfer
         complies with the requirements of Section 2.02(b)(ii) above and the
         Registrar receives the following:

         Global Note. A beneficial interest in any Restricted Global Note may be
         exchanged by any Holder thereof for a beneficial interest in an
         Unrestricted Global Note or transferred to a Person who takes delivery
         thereof in the form of a beneficial interest in an Unrestricted Global
         Note if the exchange or transfer complies with the requirements of
         Section 2.02(b)(ii) above and:

                           (A) such exchange or transfer is effected pursuant to
                  the Exchange Offer in accordance with the applicable
                  Registration Rights Agreement and the Holder of the beneficial
                  interest to be transferred, in the case of an exchange, or the

                           (B) such transfer is effected pursuant to a Shelf
                  Registration Statement in accordance with the applicable
                  Registration Rights Agreement;

                           (C) such transfer is effected by a Broker-Dealer
                  pursuant to an Exchange Offer Registration Statement in

                  or

                           (D) the Registrar receives the following:

                                    (1) if the Holder of such beneficial

                           exchange such beneficial interest for a beneficial

         Capitalized terms used herein shall have the meanings assigned to them
in the Indenture referred to below unless otherwise indicated.

         1. INTEREST. Allied Waste North America, Inc., a Delaware corporation
(the "COMPANY"), promises to pay interest on the principal amount of this Note
at 6-1/2% per annum from the date hereof until maturity and shall pay the
Special Interest, if any, payable pursuant to Section 5 of the Registration
Rights Agreement referred to below. The Company shall pay interest and Special
Interest semi-annually in arrears on February 15 and August 15 of each year,
beginning August 15, 2004, or if any such day is not a Business Day, on the next
succeeding Business Day (each an "Interest Payment Date"). Interest on the Notes
shall accrue from the most recent date to which interest has been paid or, if no
interest has been paid, from the date of issuance; provided that if there is no
existing Default in the payment of interest, and if this Note is authenticated
between a record date referred to on the face hereof and the next succeeding
Interest Payment Date, interest shall accrue from such next succeeding Interest
Payment Date; provided, further, that the first Interest Payment Date shall be
August 15, 2004. The Company shall pay interest (including post-petition
interest in any proceeding under any Bankruptcy Law) on overdue principal and
premium, if any, from time to time on demand at a rate that is 2% per annum in
excess of the rate then in effect; it shall pay interest (including
post-petition interest in any proceeding under any Bankruptcy Law) on overdue
installments of interest and Special Interest, if any, from time to time on
demand at the same rate to the extent lawful. Interest shall be computed on the
basis of a 360 day year of twelve 30 day months.

         2. METHOD OF PAYMENT. The Company shall pay interest on the Notes
(except defaulted interest) and Special Interest, if any, to the Persons who are
registered Holders of Notes at the close of business on the February 1 or August
1 next preceding the Interest Payment Date, even if such Notes are canceled
after such record date and on or before such Interest Payment Date, except as
provided in Section 3.7(b) of the Indenture with respect to defaulted interest.
The Notes shall be payable as to principal, premium, interest and Special
Interest, if any, at the office or agency of the Company maintained for such
purpose within or without the City and State of New York, or, at the option of
the Company, payment of interest and Special Interest, if any, may be made by
check mailed to the Holders at their addresses set forth in the register of
Holders, and provided that payment by wire transfer of immediately available
funds shall be required with respect to principal of and interest, premium and
Special Interest, if any, on all Global Notes and all other Notes the Holders of
which shall have provided wire transfer instructions to the Company or the
Paying Agent at least 10 Business Days prior to the applicable payment date.
Such payment shall be in such coin or currency of the United States of America
as at the time of payment is legal tender for payment of public and private
debts.

         3. PAYING AGENT AND REGISTRAR. Initially, U.S. Bank National
Association, the Trustee under the Indenture, shall act as Paying Agent and
Registrar. The Company may change any Paying

Agent or Registrar without notice to any Holder. The Company or any of its
Subsidiaries may act in any such capacity.

         4. INDENTURE. The Company issued the Notes under an Indenture dated as
of December 23, 1998, as amended by the Eleventh Supplemental Indenture dated as
of November 10, 2003 (together, the "INDENTURE"), each among the Company, the
Guarantors and the Trustee. The terms of the Notes include those stated in the
Indenture and those made part of the Indenture by reference to the Trust
Indenture Act of 1939, as amended (15 U.S. Code Sections 77aaa-77bbbb). The
Notes are subject to all such terms, and Holders are referred to the Indenture
and such Act for a statement of such terms. To the extent any provision of this
Note conflicts with the express provisions of the Indenture, the provisions of
the Indenture shall govern and be controlling.

         5. OPTIONAL REDEMPTION.

         (a) Except as set forth in subparagraph (b) and (c) of this Paragraph
5, the Company shall not have the option to redeem the Notes prior to the final
maturity of such Notes.

         (b) The Notes will be subject to redemption, at the option of the
Company, in whole or in part, at any time, upon not less than 30 nor more than
60 days' notice mailed to each Holder of Notes to be redeemed at such Holder's
address appearing in the Security Register, in amounts of $1,000 or an integral
multiple of $1,000, at a redemption price equal to the greater of (1) 100% of
their principal amount or (2) the sum of the present values of the remaining
scheduled payments of principal and interest thereon discounted to maturity on a
semi-annual basis (assuming a 360-day year consisting of twelve 30-day months)
at the Treasury Yield plus 50 basis points, plus in each case accrued but unpaid
interest (including Special Interest) to but excluding the Redemption Date
(subject to the rights of Holders of record on the relevant Regular Record Date
to receive interest due on an Interest Payment Date that is on or prior to the
Redemption Date).

         (c) At any time, or from time to time, prior to November 15, 2006, up
to 33-1/3% in aggregate principal amount of the Notes originally issued under
the Indenture shall be redeemable, at the option of the Company, from the net
proceeds of one or more Public Offerings of Capital Stock (other than Redeemable
Interests) of Allied, at a Redemption Price equal to 106.500% of the principal
amount thereof, together with accrued but unpaid interest to the Redemption Date
(subject to the right of Holders of record on the relevant Regular Record Date
to receive interest due on an Interest Payment Date that is on or prior to the
Redemption Date); provided that the notice of redemption with respect to any
such redemption is mailed within 30 days following the closing of the
corresponding Public Offering.

         6. MANDATORY REDEMPTION. Except as set forth in paragraph 7 below, the
Company shall not be required to make mandatory redemption payments with respect
to the Notes.

         7. REPURCHASE AT OPTION OF HOLDER. The Indenture provides that, subject
to certain conditions, if (i) certain Net Available Proceeds are available to
the Company as a result of Asset Dispositions or (ii) a Change of Control
occurs, the Company shall be required to make an Offer to Purchase for all or a
specified portion of the Securities.

         8. NOTICE OF REDEMPTION. Notice of redemption shall be mailed no less
than 30 days but no more than 60 days before the redemption date to each Holder
whose Notes are to be redeemed at its registered address. Notes in denominations
larger than $1,000 may be redeemed in part but only in whole

                                      A-3
<PAGE>
                                                                       EXHIBIT A



multiples of $1,000, unless all of the Notes held by a Holder are to be
redeemed. On and after the redemption date interest ceases to accrue on Notes or
portions thereof called for redemption.

         9. DENOMINATIONS, TRANSFER, EXCHANGE. The Notes are in registered form
without coupons in denominations of $1,000 and integral multiples of $1,000. The
transfer of Notes may be registered and Notes may be exchanged as provided in
the Indenture. The Registrar and the Trustee may require a Holder, among other
things, to furnish appropriate endorsements and transfer documents and the
Company may require a Holder to pay any taxes and fees required by law or
permitted by the Indenture. The Company need not exchange or register the
transfer of any Note or portion of a Note selected for redemption, except for
the unredeemed portion of any Note being redeemed in part. Also, the Company
need not exchange or register the transfer of any Notes for a period of 15 days
before a selection of Notes to be redeemed or during the period between a record
date and the corresponding Interest Payment Date.

         10. PERSONS DEEMED OWNERS. The registered Holder of a Note may be
treated as its owner for all purposes.

         11. AMENDMENT, SUPPLEMENT AND WAIVER. The Indenture permits, with
certain exceptions as therein provided, the amendment thereof and the
modification of the rights and obligations of the Company and the Guarantors and
the rights of the Holders of the Securities under the Indenture at any time by
the Company, the Guarantors and the Trustee with the consent of the Holders of a
majority in aggregate principal amount of the Notes at the time.

         12. DEFAULTS AND REMEDIES. Events of Default include: (i) default for
30 days in the payment when due of interest on the Notes; (ii) default in
payment when due of principal of or premium, if any, on the Notes when the same
becomes due and payable at maturity, upon redemption (including in connection
with an Offer to Purchase) or otherwise, (iii) failure by the Company to comply
with subsections 12(a) or 12(b) of Section 1.01 of the Indenture or Article 7 of
the Indenture (as superseded by subsection 13 of Section 1.01 of the Eleventh
Supplemental Indenture); (iv) failure by the Company for 60 days after notice to
the Company or the Holders of at least 10% in principal amount of the Notes
(including Additional Notes, if any) then outstanding voting as a single class
to comply with certain other agreements in the Indenture and the Notes; (v)
default under certain other agreements relating to Debt of the Company which
default results in the acceleration of such Debt prior to its express maturity;
(vi) certain final judgments for the payment of money that remain undischarged
for a period of 60 days; and (vii) certain events of bankruptcy or insolvency
with respect to the Company or any of its Material Subsidiaries. If any Event of
Default (other than an Event of Default of the type described in clause (vii)
above) occurs and is continuing, the Trustee or the Holders of at least 25% in
principal amount of the then outstanding Notes may declare all the Notes to be
due and payable. Notwithstanding the foregoing, in the case of an Event of
Default arising from certain events of bankruptcy or insolvency, all outstanding
Notes shall become due and payable without further action or notice; provided,
however, that after such acceleration, but before a judgment or decree based on
acceleration, the Holders of a majority in aggregate principal amount of
Outstanding Notes of such issue may, under certain circumstances, rescind and
annul such acceleration if all Events of Default, other than the non-payment of
accelerated principal, have been cured or waived as provided in the Indenture.
Holders may not enforce the Indenture or the Notes except as provided in the
Indenture. Subject to certain limitations, Holders of a majority in principal
amount of the then outstanding Notes may direct the Trustee in its exercise of
any trust or power. The Trustee may withhold from Holders of the Notes notice of
any continuing Default or Event of Default (except a Default or Event of Default
relating to the payment of principal or interest) if it determines that
withholding notice is in their interest. The Holders of a majority in aggregate
principal amount of the Notes then outstanding by notice to the Trustee may on
behalf of the Holders of all of the Notes waive any existing Default or Event of
Default and its consequences under the Indenture except a

continuing Default or Event of Default in the payment of interest on, or the
principal of, the Notes. The Company is required to deliver to the Trustee
annually a statement regarding compliance with the Indenture, and the Company is
required upon becoming aware of any Default or Event of Default, to deliver to
the Trustee a statement specifying such Default or Event of Default.

         13. TRUSTEE DEALINGS WITH COMPANY. The Trustee, in its individual or
any other capacity, may make loans to, accept deposits from, and perform
services for the Company or its Affiliates, and may otherwise deal with the
Company or its Affiliates, as if it were not the Trustee.

         14. NO RECOURSE AGAINST OTHERS. A director, officer, employee,
incorporator or stockholder, of the Company, as such, shall not have any
liability for any obligations of the Company under the Notes or the Indenture or
for any claim based on, in respect of, or by reason of, such obligations or
their creation. Each Holder by accepting a Note waives and releases all such
liability. The waiver and release are part of the consideration for the issuance
of the Notes.

         15. AUTHENTICATION. This Note shall not be valid until authenticated by
the manual signature of the Trustee or an authenticating agent.

         16. ABBREVIATIONS. Customary abbreviations may be used in the name of a
Holder or an assignee, such as: TEN COM (= tenants in common), TEN ENT (=
tenants by the entireties), JT TEN (= joint tenants with right of survivorship
and not as tenants in common), CUST (= Custodian), and U/G/M/A (= Uniform Gifts
to Minors Act).

         17. ADDITIONAL RIGHTS OF HOLDERS OF RESTRICTED GLOBAL NOTES AND
RESTRICTED DEFINITIVE NOTES. In addition to the rights provided to Holders of
Notes under the Indenture, Holders of Restricted Global Notes and Restricted
Definitive Notes shall have all the rights set forth in the Registration Rights
Agreement relating to the Notes dated as of November 10, 2003, among the
Company, the Guarantors and the parties named on the signature pages thereof or,
in the case of Additional Notes, Holders of Restricted Global Notes and
Restricted Definitive Notes shall have the rights set forth in one or more
registration rights agreements, if any, between the Company and the other
parties thereto, relating to rights given by the Company to the purchasers of
any Additional Notes (collectively, the "Registration Rights Agreement").

         18. CUSIP NUMBERS. Pursuant to a recommendation promulgated by the
Committee on Uniform Security Identification Procedures, the Company has caused
CUSIP numbers to be printed on the Notes and the Trustee may use CUSIP numbers
in notices of redemption as a convenience to Holders. No representation is made
as to the accuracy of such numbers either as printed on the Notes or as
contained in any notice of redemption and reliance may be placed only on the
other identification numbers placed thereon.

         The Company shall furnish to any Holder upon written request and
without charge a copy of the Indenture and/or the Registration Rights Agreement.
