                           unless the Board determines that such person or group
                           is making a "hostile acquisition;"

                  (iv)     a majority of the members of the Board are not
                           Continuing Directors, where a "CONTINUING DIRECTOR"
                           is any member of the Board who (x) was a member of
                           the Board on the date of the award or (y) was

                           employ of the Company or a Subsidiary after the Grant
                           Date, or

                  (ii)     with the consent of the Board, retires after the
                           Grant Date from the Company or a Subsidiary under a

                  (iii)    ceases to be employed by the Company or any
                           Subsidiary as the result of a termination by the

                  4. Termination of Rights and Forfeiture of Common Stock.
Except for Shares that have become nonforfeitable, all of the Shares will be

forfeiture, any certificate(s) representing the Shares will be canceled.

                  5. Dividend, Voting and Other Rights. Except as otherwise
provided in this Agreement, the Grantee will have all of the rights of a
shareholder with respect to the Shares, including the right to vote the Shares
and receive any dividends that may be paid thereon; provided, however, that any
additional shares of Common Stock or other securities that the Grantee may
become entitled to receive pursuant to a stock dividend, stock split,
combination of shares, recapitalization, merger, consolidation, separation or
reorganization or any other change in the capital structure of the Company will
be subject to the same restrictions as the Shares.

                  6. Retention of Stock Certificate(s) by Company. Any
certificates representing Shares will be held in custody by the Company together
with a stock power endorsed in blank by the Grantee with respect thereto, until
those shares have become nonforfeitable in accordance with Section 3.

                  7. Compliance with Law. The Company shall make reasonable
efforts to comply with all applicable federal, state and other applicable
securities laws; provided, however, notwithstanding any other provision of this
Agreement, the Company will not be obligated to issue any securities pursuant to
this Agreement if the issuance thereof would result in a violation of any such
law. Grantee acknowledges that Grantee is a senior manager of the Company, has
complete access to the Company's financial and other information, is fully
capable of making an investment decision concerning the Company's Common Stock
without assistance of third parties, and has no intention to distribute any of
the Shares to third parties.

                  8. Withholding Taxes. If the Company is required to withhold
any federal, state, local or foreign tax in connection with any issuance of
restricted or nonrestricted shares of Common Stock or other securities pursuant
to this Agreement, the Grantee shall pay the tax or make provisions that are
satisfactory to the Company for the payment thereof.

                  9. Right to Terminate Employment. No provision of this
Agreement will limit in any way whatsoever any right that the Company or a
Subsidiary may otherwise have to terminate the employment of the Grantee at any
time.

                  10. Relation to Other Benefits. Any economic or other benefit
to the Grantee under this Agreement will not be taken into account in
determining any benefits to which the Grantee may be entitled under any
profit-sharing, retirement or other benefit or compensation plan maintained by
the Company or a Subsidiary and will not affect the amount of any insurance
coverage available to any beneficiary under any insurance plan covering
employees of the Company or a Subsidiary.

                  11. Severability. In the event that one or more of the
provisions of this Agreement are invalidated for any reason by a court of
competent jurisdiction, any provision so invalidated will be deemed to be
separable from the other provisions hereof, and the remaining provisions hereof
will continue to be valid and fully enforceable.

                  12. Governing Law. This Agreement is made under, and will be
construed in accordance with, the laws of the State of Ohio without regard to
conflict of law principles of such state.

                  13. Restrictive Legends. The Grantee acknowledges that the
Shares are subject to the terms of this Agreement and to transfer restrictions
imposed by the securities laws, and that the certificates representing the

      Restricted Subsidiary, as the case may be) receives consideration at the
      time of such disposition at least equal to the fair market value of the

      marketable cash equivalents, (B) the assumption of Debt or other
      liabilities reflected on the consolidated balance sheet of the Company and
      its Restricted Subsidiaries in accordance with generally accepted

      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

      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 Tenth 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

                                       4
<PAGE>

      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.

            (b) Change of Control.

            Within 30 days following the date the Company becomes aware of the
      consummation of a transaction that results in a Change of Control (as
      defined below), the Company shall commence an Offer to Purchase all
      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 Tenth 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), acting
      together that would constitute a "Group" (a "GROUP") for purposes of
      Section 13(d) of the Exchange Act (an "ALLIED 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 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 have not been approved by

      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 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 Restricted Payment under this Tenth Supplemental
      Indenture after giving pro forma effect to such transaction, or (III) a
      combination thereof, and the beneficial owners of the Voting Stock of
      Allied immediately

      transaction (or series), beneficially own Voting Stock representing more
      than 50% of the total voting power of all classes of Voting Stock of
      Allied (or in the case of a transaction (or series) in 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 Company immediately prior to such transaction (or
      series) receive (I) solely Voting Stock of the Company (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 Restricted Payment
      under this Tenth Supplemental Indenture after giving pro forma effect to
      such transaction, or (III) a combination thereof, and the beneficial
      owners of the Voting Stock of the Company immediately prior to such
      transaction (or series) do not, immediately after such transaction (or
      series), beneficially own Voting Stock representing more than 50% of the
      total voting power of all classes of Voting Stock of the Company (or in

      successor to the Company, of the successor entity).

            The Company shall comply with the requirements of Rule 14e-1 under
      the Exchange Act and any other securities laws and regulations thereunder
      to the extent such laws and regulations are applicable in connection with
      the repurchase of the Notes resulting from a Change of Control.

            The Company and the Trustee shall perform their respective
      obligations specified in the Offer Document for the Offer to Purchase.
      Prior to the Purchase Date, the Company shall (i) accept for payment Notes
      or portions thereof tendered pursuant to the Offer to Purchase, (ii)
      deposit with the Paying Agent (or, if the Company is acting as its own

      the Indenture) money sufficient to pay the Purchase Price of all Notes or
      portions thereof so accepted and (iii) deliver or cause to be delivered to
      the Trustee all Notes so accepted together with an Officers' Certificate
      stating the Notes or portions thereof accepted for payment by the Company.

      deliver to Holders of Notes so accepted payment in an amount equal to the
      Purchase Price for each $1,000 of Notes so accepted, and the Company shall
      promptly execute a new Note or Notes equal in principal amount to any
      unpurchased portion of the Note surrendered as requested by the Holder,

      Company shall publicly announce the results of the Offer to Purchase on or
      as soon as practicable after the Purchase Date.

            (c) Changes in Covenants when Senior Notes rated Investment Grade.

            Following the first date upon which the Notes are rated the
      following: (i) Baa3 or better by Moody's Investors Service, Inc.
      ("MOODY'S") and BB+ or better by Standard & Poor's Ratings Group ("S&P");
      or (ii) BBB- or better by S&P and Ba1 or better by Moody's (a "RATING
      EVENT") (or, in any case, if such person ceases to rate the Notes for
      reasons outside of the control of the Company, the equivalent investment
      grade credit rating from any other "nationally recognized statistical
      rating organization" (within the meaning of Rule 15c3-1(c)(2)(vi)(F) under
      the Exchange Act) selected by the Company as a replacement agency) (the
      "RATING EVENT DATE") (and provided no Event of Default or event that with
      notice or the passage of time would constitute an Event of Default shall
      exist on the Rating Event Date), the covenants specifically listed under
      subsections 12(a), 12(d), 12(e), 12(f), 12(h) and 12(j) of this Section
      1.01 of this Tenth Supplemental Indenture shall no longer be applicable to
      the Notes. At no time after a Rating Event Date will the provisions and
      covenants contained in this Tenth Supplemental Indenture at the time of
      the issuance of the Notes that cease to be applicable after the Rating
      Event Date be reinstated.

            (d) Limitation on Consolidated Debt.

            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:

                  (i) Debt under the Credit Facility in an aggregate principal
            amount at any one time outstanding not to exceed the amount
            permitted to be borrowed thereunder;

            Debt owed by a Restricted Subsidiary to the Company or to a
            Restricted Subsidiary; provided, however, that in the event that
            either (x) the Company or the Restricted Subsidiary to which such
            Debt is owed transfers or otherwise disposes of such Debt to a
            Person other than the Company or 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 Restricted Subsidiary;

                                       7

            consolidation transaction permitted under the provisions described
            under Section 7.1 of the Indenture (as superseded by subsection 13
            of this Section 1.01 of this Tenth 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 Subsidiary) and was not issued in contemplation of such
            transaction, or (y) is issued by the Company or a Restricted
            Subsidiary to a seller in connection with such transaction, in an
            aggregate amount for all such Debt issued pursuant to the provisions
            of this Tenth Supplemental Indenture described under this clause (v)
            and then outstanding does not exceed 7.5% of the Consolidated Total
            Assets of the Company at the time of such Incurrence;

                  (vi) Debt consisting of Permitted Interest Rate or Currency
            Protection Agreements;

                  (vii) Debt Incurred to renew, extend, refinance or refund any
            outstanding Debt permitted in the preceding paragraph or in clauses
            (i) through (v) above or Incurred pursuant to this clause (vii);
            provided, however, that such 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, extended, refinanced or refunded) ("Permitted Refinancing
            Debt"); and

                  (viii) Debt not otherwise permitted to be Incurred pursuant to
            clauses (i) through (vii) above, which, in aggregate amount,
            together with the aggregate amount of all other Debt previously
            Incurred pursuant to the provisions of this clause (viii) and then
            outstanding, does not exceed 7.5% of the Consolidated Total Assets
            of the Company at the time of such Incurrence.

            (e) Limitation on Restricted Payments.

      The Company shall not, and shall not permit any Restricted Subsidiary to,

Wholly-Owned Restricted Subsidiary); (iii) make any Investment that is not a
Permitted Investment; or (iv) redeem, defease, repurchase, retire or otherwise
acquire or retire for value prior to any scheduled maturity, repayment or

            (1) an Event of Default, or an event that with the lapse of time or
      the giving of notice, or both, would constitute an Event of Default, shall
      have occurred and be continuing; or

            (2) the Company would, at the time of such Restricted Payment and
      after giving pro forma effect thereto as if such Restricted Payment had
      been made 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 Restricted Payment, not 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 paragraph
      under subsection 12(d) of this Section 1.01 of this Tenth Supplemental
      Indenture; or

      all Restricted Payments (excluding Restricted Payments permitted by
      clauses (ii), (iii), (iv), (v) and (vii) of the next succeeding paragraph)
      from the date of this Tenth Supplemental Indenture (the amount so
      expended, if other than in cash, determined in good faith by the Board of
      Directors) exceeds the sum, without duplication, of: (a) 50% of the
      aggregate Consolidated Net Income (or, in case Consolidated Net Income
      shall be negative, less 100% of such deficit) for the period (taken as one
      accounting period) from the beginning of the second fiscal quarter of

      convertible into Capital Stock) of the Company and the principal amount of
      Debt and Redeemable Interests of the Company that has been converted into
      Capital Stock (other than Redeemable Interests) of the Company after
      January 30, 2001, provided that any such net proceeds received by the
      Company from an employee stock ownership plan financed by loans from the
      Company or a Subsidiary of the Company shall be included only to the
      extent such loans have been repaid with cash on or prior to the date of
      determination; (c) 50% of any dividends received by the Company or a
      Wholly-Owned Restricted Subsidiary after January 30, 2001 from an

      The foregoing covenant shall not be violated by reason of

            (i) the payment of any dividend within 60 days after declaration
      thereof if at the declaration date such payment would have complied with
      the foregoing covenant;

            (ii) any refinancing or refunding of Debt permitted if such

      Supplemental Indenture;

            (iii) the purchase, redemption or other acquisition or retirement
      for value of any Debt or Capital Stock of the Company or any options,

      substantially concurrent issuance or sale (other than to a Restricted
      Subsidiary of the Company) of Capital Stock (other than Redeemable
      Interests) of the Company; provided that the amount of any such net cash
      proceeds that are utilized for any such purchase, redemption or other
      acquisition or retirement for value shall be excluded from clause (3)(b)
      in the foregoing paragraph of this subsection 12(e);

            (iv) the repurchase, redemption, defeasance, retirement, refinancing

      provision contained in subsection 12(b) of this Section 1.01 of this Tenth
      Supplemental Indenture; provided that prior to such repurchase the Company
      has made the Change of Control Offer (the "CHANGE OF CONTROL OFFER") as
      provided in such covenant with respect to the Notes and repurchased all
      Notes validly tendered for repayment in connection with such Change of
      Control Offer;

            (vi) the purchase or redemption of any Debt from Net Available
      Proceeds to the extent permitted under subsection 12(a) of this Section

      refinancing or acquisition for value the principal of the Subordinated
      Notes; and

            (viii) payments pursuant to the Intercompany Agreements.

      Upon the designation of any Restricted Subsidiary as an Unrestricted
Subsidiary, an amount equal to the greater of the book value and the fair market
value of all assets of such Restricted Subsidiary at the end of the Company's
most recently ended fiscal quarter for which internal financial statements are
available prior to such designation shall be deemed to be a Restricted Payment
at the time of such designation for purposes of calculating the aggregate amount
of Restricted Payments (including the Restricted Payment resulting from such
designation) permitted under this subsection 12(e) of Section 1.01 of this Tenth
Supplemental Indenture.

      (f) Limitations Concerning Distributions by Subsidiaries, Etc.

      The Company shall not, and shall not permit any Restricted Subsidiary to,

                                       10
<PAGE>

respect of its Capital Stock or other ownership interests or pay any Debt or
other obligation owed to the Company or any other Restricted Subsidiary, (ii) to
make loans or advances to the Company or any other Restricted Subsidiary, or
(iii) to sell, lease or transfer any of its property or assets to the Company or
any Wholly-Owned Restricted Subsidiary, except, in any such case, any
encumbrance or restriction existing pursuant to: (a) the Notes, the Indenture,
the Senior Guarantees or any other agreement in effect on the date of this Tenth
Supplemental Indenture; (b) the Credit Facility, including any Guarantees of or
Liens securing the Debt Incurred thereunder; (c) an agreement relating to any
Debt Incurred by such Subsidiary prior to the date on which such Subsidiary was
acquired by the Company and outstanding on such date and not incurred in
anticipation of becoming a Subsidiary; (d) an agreement which has been entered
into for the pending sale or disposition of all or substantially all of the

that such restriction terminates upon consummation or abandonment of such
disposition and upon termination of such agreement; (e) customary non-assignment
provisions in leases and other agreements entered into in the ordinary course of
business; (f) restrictions contained in any security agreement (including a
capital lease) securing Debt permitted to be Incurred under this Tenth
Supplemental Indenture that impose restrictions of the nature described in
clause (iii) above on the property subject to the Lien of such security
agreement; (g) an agreement effecting a renewal, extension, refinancing or
refunding of Debt incurred pursuant to an agreement referred to in clause (a),
(b) or (f) above; provided, however, that the provisions relating to such
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 distributions.

      (g) Limitation on Liens.

      Allied shall not, and the Company shall not, and shall not permit any of
its Restricted Subsidiaries to, create, Incur, assume or otherwise cause or
suffer to exist or become effective any Lien (other than Permitted Liens) upon
any of their property or assets, now owned or hereafter acquired to secure Debt
of Allied, the Company or any of its Restricted Subsidiaries.

      (h) Limitation on Transactions with Affiliates and Related Persons.

      The Company shall not, and shall not permit any of its Restricted
Subsidiaries to, make any payment to, or sell, lease, transfer or otherwise
dispose of any of its properties or assets to, or purchase any property or
assets from, or enter into or make or amend any transaction, contract,
agreement, understanding, loan, advance or guarantee with, or for the benefit
of, any Affiliate of the Company (each of the foregoing, an "AFFILIATE
TRANSACTION"), unless: (a) such Affiliate Transaction is on terms that are no
less favorable to the Company or such Restricted Subsidiary than those that
would have been obtained in a comparable transaction by the Company or such
Restricted Subsidiary with an unrelated Person; and (b) the Company delivers to
the Trustee, with respect to any Affiliate Transaction or series of related
Affiliate Transactions involving aggregate consideration in excess of $10
million, either: (i) a 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

                                       11
<PAGE>

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

outstanding; provided that such limitation shall not apply to loans the proceeds

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 Tenth 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 Tenth 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 (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.

                                       12

      (j) Unrestricted Subsidiaries.

      The Company at any time may designate any Person that is a Subsidiary, or
after the date of this Tenth 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 Tenth 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

                                       13
<PAGE>

      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 Tenth 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 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,

                                       14
<PAGE>

      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 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 (to the extent permitted by law) on the Notes and performance of
all other obligations of the Company to the Holders of Notes or the Trustee
under this Tenth 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 Tenth
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 Tenth 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.

                  (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).

                                       15
<PAGE>

            (b) Release of Collateral.

                  (i) Subject to this subsection 14(b) of this Section 1.01 of
      this Tenth 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 Tenth Supplemental Indenture or the Security Agreements.

                  (ii) The release of any Collateral from the terms of this
      Tenth Supplemental Indenture and the Security Agreements shall not be
      deemed to impair the security under this Tenth 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 Tenth
      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
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 Tenth 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.

                                       16
<PAGE>

            (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 Tenth Supplemental Indenture.

            (e) Termination of Security Interest. Upon (1) the full and final
payment and performance of all obligations of the Company under this Tenth
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 Tenth 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 Tenth 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 Tenth 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 Tenth 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 action

      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

Holder of a Definitive Note may exchange such Note for a beneficial interest in

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 Tenth
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.

Committee on Uniform Security Identification Procedures, the Company has caused
