        (a)    General.    The Notes and the Trustee's certificate of authentication will be substantially in the form of
Exhibit A hereto. The Notes may have notations, legends or endorsements required by law, stock exchange rule or usage. Each Note will be dated the date of its authentication. The Notes shall be
in denominations of $1,000 and integral multiples thereof and shall be issued only against payment in immediately available funds. 


        The
terms and provisions contained in the Notes will constitute, and are hereby expressly made, a part of this Indenture and the Company, the Guarantors and the Trustee, by their
execution and delivery of this Indenture, expressly agree to such terms and provisions and to be bound thereby. However, to the extent any provision of any Note conflicts with the express provisions
of this Indenture, the provisions of this Indenture shall govern and be controlling. 



        (b)    Global Notes.    Notes issued in global form will be substantially in the form of Exhibits A1 or A2 attached
hereto (including the Global Note Legend thereon and the "Schedule of Exchanges of Interests in the Global Note" attached thereto). Notes issued in definitive form will be substantially in the form of
Exhibit A1 attached hereto (but without the Global Note Legend thereon and without the "Schedule of Exchanges of Interests in the Global Note" attached thereto). Each Global Note will represent such
of the outstanding Notes as will be specified therein and each shall provide that it represents the aggregate principal amount of outstanding Notes from time to time endorsed thereon and that the
aggregate principal amount of outstanding Notes represented thereby may from time to time be reduced or increased, as appropriate, to reflect exchanges and redemptions. Any endorsement of a Global
Note to reflect the amount of any increase or decrease in the aggregate principal amount of outstanding Notes represented thereby will be made by the Trustee or the Custodian, at the direction of the
Trustee, in accordance with instructions given by the Holder thereof as required by Section 2.06 hereof. 


        (c)    Temporary Global Notes.    Notes offered and sold in reliance on Regulation S will be issued initially
in the form of the Regulation S Temporary Global Note, which will be deposited on behalf of the purchasers of the Notes represented thereby with the Trustee, as custodian for the Depositary,
and registered in the name of the Depositary or the nominee of the Depositary for the accounts of designated agents holding on behalf of Euroclear or Clearstream Bank, duly executed by the Company and
authenticated by the Trustee as hereinafter provided. The Restricted Period will be terminated upon the receipt by the Trustee of: 



        (1)   a
written certificate from the Depositary, together with copies of certificates from Euroclear and Clearstream Bank certifying that they have received certification of
non-United States beneficial ownership of 100% of the aggregate principal amount of the Regulation S Temporary Global Note (except to the extent of any beneficial owners thereof who
acquired an interest therein during the Restricted Period pursuant to another exemption from registration under the Securities Act and who will take delivery of a beneficial ownership interest in a
144A Global Note bearing a Private Placement Legend, all as contemplated by Section 2.06(b) hereof); and 


        (2)   an
Officers' Certificate from the Company.

the termination of the Restricted Period, beneficial interests in the Regulation S Temporary Global Note will be exchanged for beneficial interests in

Regulation S Temporary Global Note. The aggregate principal amount of the Regulation S Temporary Global Note and the Regulation S Permanent Global Notes may from time to time be
increased or decreased by adjustments made on the records of the Trustee and the Depositary or its nominee, as the case may be, in connection with transfers of interest as hereinafter provided. 



        (3)    Euroclear and Clearstream Procedures Applicable.    The provisions of the "Operating Procedures of the

        Two
Officers must sign the Notes for the Company by manual or facsimile signature. 


        If
an Officer whose signature is on a Note no longer holds that office at the time a Note is authenticated, the Note will nevertheless be valid. 


        A
Note will not be valid until authenticated by the manual signature of the Trustee. The signature will be conclusive evidence that the Note has been authenticated under this Indenture. 



        The
Trustee will, upon receipt of a written order of the Company signed by two Officers (an "Authentication Order"), authenticate Notes
for original issue up to the aggregate principal amount set forth in such Authentication Order. The aggregate principal amount of Notes outstanding at any time may not exceed the aggregate amount of
Notes authenticated for original issue pursuant to all Authentication Orders issued by the Company, except as provided in Section 2.07 hereof. 


        The
Trustee may appoint an authenticating agent acceptable to the Company to authenticate Notes. An authenticating agent may authenticate Notes whenever the Trustee may do so. Each
reference in this Indenture to authentication by the Trustee includes authentication by such agent. An authenticating agent has the same rights as an Agent to deal with Holders or an Affiliate of the
Company. 


Section 2.03    Registrar and Paying Agent.    


        The
Company will maintain an office or agency where Notes may be presented for registration of transfer or for exchange ("Registrar") and
an office or agency where Notes may be presented for payment ("Paying Agent"). The Registrar will keep a register of the Notes and of their transfer and
exchange. The Company may appoint one or more co-registrars and one or more additional paying agents. The term "Registrar" includes any co-registrar and the term "Paying Agent"
includes any additional paying agent. The Company may change any Paying Agent or Registrar without notice to any Holder. The Company will notify the Trustee in writing of the name
and address of any Agent not a party to this Indenture. If the Company fails to appoint or maintain another entity as Registrar or Paying Agent, the Trustee shall act as such. The Company or any of
its Subsidiaries may act as Paying Agent or Registrar. 


        The
Company initially appoints The Depository Trust Company ("DTC") to act as Depositary with respect to the Global Notes.

Section 2.04    Paying Agent to Hold Money in Trust.    


        The
Company will require each Paying Agent other than the Trustee to agree in writing that the Paying Agent will hold in trust for the benefit of Holders or the Trustee all money held by
the Paying Agent for the payment of principal, premium or Additional Interest, if any, or interest on the Notes, and will notify the Trustee of any default by the Company in making any such payment.
While any such default continues, the Trustee may require a Paying Agent to pay all money held by it to the Trustee. The Company at any time may require a Paying Agent to pay all money held by it to
the Trustee. Upon payment over to the Trustee, the Paying Agent (if other than the Company or a Subsidiary) will have no further liability for the money. If the Company or a Subsidiary acts as Paying
Agent, it will segregate and hold in a separate trust fund for the benefit of the Holders all money held by it as Paying Agent. Upon any bankruptcy or reorganization proceedings relating to the
Company, the Trustee will serve as Paying Agent for the Notes. 


Section 2.05    Holder Lists.    


        The
Trustee will preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of all Holders and shall otherwise comply with
TIA § 312(a). If the Trustee is not the Registrar, the Company will furnish to the Trustee at least seven Business Days before each interest payment date and at such other times as the
Trustee may request in writing, a list in such form and as of such date as the Trustee may reasonably require of the names and addresses of the Holders of Notes and the Company shall otherwise comply
with TIA § 312(a). 


Section 2.06    Transfer and Exchange.    


        (a)    Transfer and Exchange of Global 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 will be exchanged by the Company for Definitive Notes if: 



        (1)   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 120 days after the date of such notice from the Depositary; or 


        (2)   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; provided that in no event shall the Regulation S Temporary Global Note be exchanged by the Company for Definitive
Notes prior to (x) the expiration of the Restricted Period and (y) the receipt by the Registrar of any certificates required pursuant to Rule 903(b)(3)(ii)(B) under the Securities
Act.

        (i)    General Provisions Relating to Transfers and Exchanges.    



        (1)   To
permit registrations of transfers and exchanges, the Company will execute and the Trustee will authenticate Global Notes and Definitive Notes upon receipt of an
Authentication Order in accordance with Section 2.02 or at the Registrar's request. 


        (2)   No
service charge will be made to a Holder of a Global Note or to a Holder of a Definitive Note for any registration of transfer or exchange, but the Company may require
payment of a sum sufficient to cover any transfer tax or similar governmental charge payable in connection therewith (other than any such transfer taxes or similar governmental charge payable upon
exchange or transfer pursuant to Sections 2.10, 3.06, 3.09, 4.10, 4.15 and 9.05 hereof). 



        (3)   The
Registrar will not be required to register the transfer of or exchange any Note selected for redemption in whole or in part, except the unredeemed portion of any
Note being redeemed in part. 


        (4)   All
Global Notes and Definitive Notes issued upon any registration of transfer or exchange of Global Notes or Definitive Notes will be the valid obligations of the
Company, evidencing the same debt, and entitled to the same benefits under this Indenture, as the Global Notes or Definitive Notes surrendered upon such registration of transfer or exchange. 


        (5)   The
Company will not be required: 



        (A)  to
issue, to register the transfer of or to exchange any Notes during a period beginning at the opening of business 15 days before the day of any selection of
Notes for 




31





 


redemption
under Section 3.02 hereof and ending at the close of business on the day of selection; 


        (B)  to
register the transfer of or to exchange any Note selected for redemption in whole or in part, except the unredeemed portion of any Note being redeemed in part; or 



        (C)  to
register the transfer of or to exchange a Note between a record date and the next succeeding interest payment date. 




        (6)   Prior
to due presentment for the registration of a transfer of any Note, the Trustee, any Agent and the Company may deem and treat the Person in whose name any Note is
registered as the absolute owner of such Note for the purpose of receiving payment of principal of and interest on such Notes and for all other purposes, and none of the Trustee, any Agent or the
Company shall be affected by notice to the contrary. 


        (7)   The
Trustee will authenticate Global Notes and Definitive Notes in accordance with the provisions of Section 2.02 hereof. 


        (8)   All
certifications, certificates and Opinions of Counsel required to be submitted to the Registrar pursuant to this Section 2.06 to effect a registration of
transfer or exchange may be submitted by facsimile. 




Section 2.07    Replacement Notes.    



        If
any mutilated Note is surrendered to the Trustee or the Company and the Trustee receives evidence to its satisfaction of the destruction, loss or theft of any Note, the Company will
issue and the Trustee, upon receipt of an Authentication Order, will authenticate a replacement Note if the Trustee's requirements are met. If required by the Trustee or the Company, an indemnity bond
must be supplied by the Holder that is sufficient in the judgment of the Trustee and the Company to protect the Company, the Trustee, any Agent and any authenticating agent from any loss that any of
them may suffer if a Note is replaced. The Company may charge for its expenses in replacing a Note. 



        Every
replacement Note is an additional obligation of the Company and will be entitled to all of the benefits of this Indenture equally and proportionately with all other Notes duly
issued hereunder. 


Section 2.08    Outstanding Notes.    


        The
Notes outstanding at any time are all the Notes authenticated by the Trustee except for those canceled by it, those delivered to it for cancellation, those reductions in the interest
in a Global Note effected by the Trustee in accordance with the provisions hereof, and those described in this Section as not outstanding. Except as set forth in Section 2.09 hereof, a Note
does not cease to be outstanding because the Company or an Affiliate of the Company holds the Note; however, Notes held by the Company or an affiliate (other than notes acquired by Affiliates in the
ordinary course of their respective businesses) of the Company shall not be deemed to be outstanding for purposes of Section 3.07(b) hereof. 


        If
a Note is replaced pursuant to Section 2.07 hereof, it ceases to be outstanding unless the Trustee receives proof satisfactory to it that the replaced Note is held by a
"protected purchaser" (as defined in the Uniform Commercial Code as adopted and in effect in the State of New York). 


        If
the principal amount of any Note is considered paid under Section 4.01 hereof, it ceases to be outstanding and interest on it ceases to accrue. 



        If
the Paying Agent (other than the Company, a Subsidiary or an Affiliate of any thereof) holds, on a redemption date or maturity date, money sufficient to pay Notes payable on that
date, then on and after that date such Notes will be deemed to be no longer outstanding and will cease to accrue interest. 


32





 



Section 2.09    Treasury Notes.    



        In
determining whether the Holders of the required principal amount of Notes have concurred in any direction, waiver or consent, Notes owned by the Company, or by any Person directly or
indirectly controlling or controlled by or under direct or indirect common control with the Company, will be considered as though not outstanding, except that for the purposes of determining whether
the Trustee will be protected in relying on any such direction, waiver or consent, only Notes that the Trustee knows are so owned will be so disregarded. 


Section 2.10    Temporary Notes.    



        Until
certificates representing Notes are ready for delivery, the Company may prepare and the Trustee, upon receipt of an Authentication Order, will authenticate temporary Notes.
Temporary Notes will be substantially in the form of certificated Notes but may have variations that the Company considers appropriate for temporary Notes and as may be reasonably acceptable to the
Trustee. Without unreasonable delay, the Company will prepare and the Trustee will authenticate definitive Notes in exchange for temporary Notes. 


        Holders
of temporary Notes will be entitled to all of the benefits of this Indenture. 


Section 2.11    Cancellation.    



        The
Company at any time may deliver Notes to the Trustee for cancellation. The Registrar and Paying Agent will forward to the Trustee any Notes surrendered to them for registration of
transfer, exchange or payment. The Trustee and no one else will cancel all Notes surrendered for registration of transfer, exchange, payment, replacement or cancellation and will destroy canceled
Notes (subject to the record retention requirement of the Exchange Act). Certification of the destruction of all canceled Notes will be delivered to the Company. The Company may not issue new Notes to
replace Notes that it has paid or that have been delivered to the Trustee for cancellation. 


Section 2.12    Defaulted Interest.    



        If
the Company defaults in a payment of interest on the Notes, it will pay the defaulted interest in any lawful manner plus, to the extent lawful, interest payable on the defaulted
interest, to the Persons who are Holders on a subsequent special record date, in each case at the rate provided in the Notes and in Section 4.01 hereof. The Company will notify the Trustee in
writing of the amount of defaulted interest proposed to be paid on each Note and the date of the proposed payment. The Company will fix or cause to be fixed each such special record date and payment
date, provided that no such special record date may be less than 10 days prior to the related payment date for such defaulted interest. At least
15 days before the special record date, the Company (or, upon the written request of the Company, the Trustee in the name and at the expense of the Company) will mail or cause to be mailed to
Holders a notice that states the special record date, the related payment date and the amount of such interest to be paid. 


ARTICLE 3.

REDEMPTION AND PREPAYMENT

redemption provisions of Section 3.08 hereof, it must furnish to the Trustee, at least 30 days (or 10 days in the case of a special mandatory redemption pursuant to
Section 3.08) but not more than 60 days before a redemption date, an Officers' Certificate setting forth: 



        (1)   the

        (2)   the

Section 3.02    Selection of Notes to Be Redeemed or Purchased.    


        If
less than all of the Notes are to be redeemed or purchased in an offer to purchase at any time, the Trustee will select Notes for redemption or purchase as follows: 



        (1)   if
the Notes are listed on any national securities exchange, in compliance with the requirements of the principal national securities exchange on which the Notes are
listed; or 


        (2)   if
the Notes are not listed on any national securities exchange, on a pro rata basis, by lot or by such method as the
Trustee shall deem fair and appropriate. 




        In
the event of partial redemption or purchase by lot, the particular Notes to be redeemed or purchased will be selected, unless otherwise provided herein, not less than 30 nor more than
60 days prior to the redemption or purchase date by the Trustee from the outstanding Notes not previously called for redemption or purchase. 


        The
Trustee will promptly notify the Company in writing of the Notes selected for redemption or purchase and, in the case of any Note selected for partial redemption or purchase, the
principal amount thereof to be redeemed or purchased. Notes and portions of Notes selected will be in amounts of $1,000 or whole multiples of $1,000; except that if all of the Notes of a Holder are to
be redeemed or purchased, the entire outstanding amount of Notes held by such Holder, even if not a multiple of $1,000, shall be redeemed or purchased. Except as provided in the preceding sentence,
provisions of this Indenture that apply to Notes called for redemption or purchase also apply to portions of Notes called for redemption or purchase. 


Section 3.03    Notice of Redemption.    


        Subject
to the provisions of Sections 3.08 and 3.09 hereof, at least 30 days (or 10 days in the case of a special mandatory redemption pursuant to Section 3.08
hereof) but not more than 60 days before a redemption date, the Company will mail or cause to be mailed, by first class mail, a notice of redemption to each Holder whose Notes are to be
redeemed at its registered address, except that redemption notices may be mailed more than 60 days prior to a redemption date if the notice is issued in connection with a defeasance of the
Notes or a satisfaction and discharge of this Indenture pursuant to Articles 8 or 12 of this Indenture. 


        The
notice will identify the Notes to be redeemed and will state: 



        (1)   the
redemption date; 


        (2)   the
redemption price; 


        (3)   if
any Note is being redeemed in part, the portion of the principal amount of such Note to be redeemed and that, after the redemption date upon surrender of such Note, a
new Note or Notes in principal amount equal to the unredeemed portion will be issued upon cancellation of the original Note; 


        (4)   the
name and address of the Paying Agent; 



34











  



        (5)   that
Notes called for redemption must be surrendered to the Paying Agent to collect the redemption price; 


        (6)   that,
unless the Company defaults in making such redemption payment, interest on Notes called for redemption ceases to accrue on and after the redemption date; 



        (7)   the
paragraph of the Notes and/or Section of this Indenture pursuant to which the Notes called for redemption are being redeemed; and 


        (8)   that
no representation is made as to the correctness or accuracy of the CUSIP number, if any, listed in such notice or printed on the Notes. 




        Notices
of redemption may not be conditional. 


        At
the Company's request, the Trustee will give the notice of redemption in the Company's name and at its expense; provided, however, that
the Company has delivered to the Trustee, at least 45 days prior to the redemption date, an Officers' Certificate requesting that the Trustee give such notice and setting forth the information
to be stated in such notice as provided in the preceding paragraph. 


Section 3.04    Effect of Notice of Redemption.    


        Once
notice of redemption is mailed in accordance with Section 3.03 hereof, Notes called for redemption become irrevocably due and payable on the redemption date at the redemption
price. A notice of redemption may not be conditional. 


Section 3.05    Deposit of Redemption or Purchase Price.    



        One
Business Day prior to the redemption or purchase price date, the Company will deposit with the Trustee or with the Paying Agent money sufficient to pay the redemption or purchase
price of and accrued interest and Additional Interest, if any, on all Notes to be redeemed or purchased on that date. The Trustee or the Paying Agent will promptly return to the Company any money
deposited with the Trustee or the Paying Agent by the Company in excess of the amounts necessary to pay the redemption or purchase price of, and accrued interest and Additional Interest, if any, on,
all Notes to be redeemed or purchased. 


        If
the Company complies with the provisions of the preceding paragraph, on and after the redemption or purchase date, interest will cease to accrue on the Notes or the portions of Notes
called for redemption or purchase. If a Note is redeemed or purchased on or after an interest record date but on or prior to the related interest payment date, then any accrued and unpaid interest
shall be paid to the Person in whose name such Note was registered at the close of business on such record date. If any Note called for redemption or purchase is not so paid upon surrender for
redemption or purchase because of the failure of the Company to comply with the preceding paragraph, interest shall be paid on the unpaid principal, from the redemption or purchase date until such
principal is paid, and to the extent lawful on any interest not paid on such unpaid principal, in each case at the rate provided in the Notes and in Section 4.01 hereof. 


Section 3.06    Notes Redeemed or Purchased in Part.    



        Upon
surrender of a Note that is redeemed or purchased in part, the Company will issue and, upon receipt of an Authentication Order, the Trustee will authenticate for the Holder at the
expense of the Company a new Note equal in principal amount to the unredeemed or unpurchased portion of the Note surrendered. 


Section 3.07    Optional Redemption.    


        (a)   At
any time prior to September 1, 2006, the Company may on any one or more occasions redeem up to 35% of the aggregate principal amount of Notes issued under this
Indenture at a redemption price of 108.5% of the principal amount thereof, plus accrued and unpaid interest and 


35





 



Additional

        (2)   the
redemption occurs within 90 days of the date of the closing of such Qualified Equity Offering. 




        (b)   At
any time prior to September 1, 2007, the Company may redeem all or a part of the Notes upon not less than 30 nor more than 60 days' notice, at a
redemption price equal to the following on the date of redemption: 



        (1)   as
determined by an Independent Investment Bank, the sum of the present values of the Remaining Scheduled Payments discounted to the redemption date on a semiannual
basis (assuming a 360 day year consisting of twelve 30-day months) at the Adjusted Treasury Rate; plus in each case, 


        (2)   accrued
and unpaid interest and Additional Interest, if any, on the Notes to the applicable date of redemption. 




        (c)   At
any time on or after September 1, 2007, the Company may redeem all or a part of the Notes upon not less than 30 nor more than 60 days' notice, at the

	2009 and thereafter	 	100.000	%






        (d)   Any
redemption pursuant to this Section 3.07 and Section 3.08 shall be made pursuant to the provisions of Section 3.01 through 3.06 hereof. 


Section 3.08    Special Mandatory Redemption.    


        (a)   Except
as set forth in clause (b) of this Section 3.08 or under Sections 4.10 and 4.15 hereof, the Company is not required to make mandatory redemption
payments with respect to the Notes. 


        (b)   In
accordance with the terms and conditions of the Escrow Agreement, and using the Company Deposit (as defined in the Escrow
Agreement), the Company shall redeem all and not less than all of the Notes on September 30, 2003, or such earlier date as the Company shall
elect (the "Special Mandatory Redemption Date"), if the Acquisition has not occurred on or prior to the Special Mandatory Redemption Date, at a
redemption price equal to 100% of the aggregate principal amount of the Notes, plus accrued and unpaid interest thereon to, but not including, September 30, 2003. Upon the closing of the
Acquisition on or before the Special Mandatory Redemption Date, the foregoing provisions of this Section 3.08(b) shall be null and void. 



Section 3.09    Offer to Purchase by Application of Excess Proceeds.    


        In
the event that, pursuant to Section 4.10 hereof, the Company is required to commence an offer to all Holders to purchase Notes (an "ARC Transaction
Offer"), it will follow the procedures specified below. 


36





 



        The
ARC Transaction Offer shall be made to all Holders and all holders of other Indebtedness that is pari passu with the Notes containing
provisions similar to those set forth in this Indenture with respect to offers to purchase or redeem with the proceeds of sales of assets. The ARC Transaction Offer will remain open for a period of at
least 20 Business Days following its commencement and not more than 30 Business Days, except to the extent that a longer period is required by applicable law (the "Offer
Period"). No later than three Business Days after the termination of the Offer Period (the "Purchase Date"), the Company will
apply all Excess Proceeds (the "Offer Amount") to the purchase of Notes and such other pari passu
Indebtedness (on a pro rata basis, if applicable) or, if less than the Offer Amount has been tendered, all Notes and other Indebtedness tendered in response to the ARC Transaction Offer. Payment for
any Notes so purchased will be made in the same manner as interest payments are made. 


        If
the Purchase Date is on or after an interest record date and on or before the related interest payment date, any accrued and unpaid interest, and Additional Interest, if any, will be
paid to the Person in whose name a Note is registered at the close of business on such record date, and no additional interest will be payable to Holders who tender Notes pursuant to the ARC
Transaction Offer. 


        Upon
the commencement of an ARC Transaction Offer, the Company will send, by first class mail, a notice to the Trustee and each of the Holders, with a copy to the Trustee. The notice
will contain all instructions and materials necessary to enable such Holders to tender Notes pursuant to the ARC Transaction Offer. The notice, which will govern the terms of the ARC Transaction
Offer, will state: 



        (1)   that
the ARC Transaction Offer is being made pursuant to this Section 3.09 and Section 4.10 hereof and the length of time the ARC Transaction Offer will
remain open; 


        (2)   the
Offer Amount, the purchase price and the Purchase Date; 


        (3)   that
any Note not tendered or accepted for payment will continue to accrue interest; 


        (4)   that,
unless the Company defaults in making such payment, any Note accepted for payment pursuant to the ARC Transaction Offer will cease to accrue interest after the
Purchase Date; 


        (5)   that
Holders electing to have a Note purchased pursuant to an ARC Transaction Offer may elect to have Notes purchased in integral multiples of $1,000 only; 



        (6)   that
Holders electing to have a Note purchased pursuant to any ARC Transaction Offer will be required to surrender the Note, with the form entitled "Option of Holder to
Elect Purchase" on the reverse of the Note completed, or transfer by book-entry transfer, to the Company, a Depositary, if appointed by the Company, or a Paying Agent at the address
specified in the notice at least three days before the Purchase Date; 


        (7)   that
Holders will be entitled to withdraw their election if the Company, the Depositary or the Paying Agent, as the case may be, receives, not later than the expiration
of the Offer Period, a telegram, telex, facsimile transmission or letter setting forth the name of the Holder, the principal amount of the Note the Holder delivered for purchase and a statement that
such Holder is withdrawing his election to have such Note purchased; 


        (8)   that,
if the aggregate principal amount of Notes and other pari passu Indebtedness surrendered by Holders exceeds the
Offer Amount, the Company will select the Notes and other pari passu Indebtedness to be purchased on a pro
rata basis based on the principal amount of Notes and such other pari passu Indebtedness surrendered (with such adjustments as
may be deemed appropriate by the Company so that only Notes in denominations of $1,000, or integral multiples thereof, will be purchased); and 



37





 

        (9)   that
Holders whose Notes were purchased only in part will be issued new Notes equal in principal amount to the unpurchased portion of the Notes surrendered (or
transferred by book-entry transfer). 




        On
or before the Purchase Date, the Company will, to the extent lawful, accept for payment, on a pro rata basis to the extent necessary,
the Offer Amount of Notes and other pari passu Indebtedness tendered or portions thereof tendered pursuant to the ARC Transaction Offer, or if less than
the Offer Amount has been tendered, all Notes and other pari passu Indebtedness tendered, and will deliver to the Trustee an Officers' Certificate
stating that such Notes or portions thereof were accepted for payment by the Company in accordance with the terms of this Section 3.09. The Company, the Depositary or the Paying Agent, as the
case may be, will promptly (but in any case not later than five days after the Purchase Date) mail or deliver to each tendering Holder an amount equal to the purchase price of the Notes tendered by
such Holder and accepted by the Company for purchase, and the Company will promptly issue a new Note, and the Trustee, upon written request from the Company will authenticate and mail or deliver such
new Note to such Holder, in a principal amount equal to any unpurchased portion of the Note surrendered. Any Note not so accepted shall be promptly mailed or delivered by the Company to the Holder
thereof. The Company will publicly announce the results of the ARC Transaction Offer on the Purchase Date. 



        Other
than as specifically provided in this Section 3.09, any purchase pursuant to this Section 3.09 shall be made pursuant to the provisions of Sections 3.01 through 3.06
hereof. 


ARTICLE 4.

        The
Company will pay or cause to be paid the principal of, premium, if any, and interest and Additional Interest, if any, on the Notes on the dates and in the manner provided in the
Notes. Principal, premium, if any, and interest and Additional Interest, if any will be considered paid on the date due if the Paying Agent, if other than the Company or a Subsidiary thereof, holds as

then due. The Company will pay all Additional Interest, if any, in the same manner on the dates and in the amounts set forth in the Registration Rights Agreement.

Section 4.02    Maintenance of Office or Agency.    


        The
Company will maintain in the Borough of Manhattan, the City of New York, an office or agency (which may be an office of the Trustee or an affiliate of the Trustee, Registrar or
co-registrar) where Notes may be surrendered for registration of transfer or for exchange and where notices and demands to or upon the Company in respect of the Notes and this Indenture
may be served. The Company will give prompt written notice to the Trustee of the location, and any change in the location, of such office or agency. If at any time the Company fails to maintain any
such required office or agency or fails to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office of the
Trustee. 


38





 



        The
Company may also from time to time designate one or more other offices or agencies where the Notes may be presented or surrendered for any or all such purposes and may from time to
time rescind such designations; provided, however, that no such designation or rescission will in any manner relieve the Company of its obligation to
maintain an office or agency in the Borough of Manhattan, the City of New York for such purposes. The Company will give prompt written notice to the Trustee of any such designation or rescission and
of any change in the location of any such other office or agency. 


        The
Company hereby designates the Corporate Trust Office of the Trustee as one such office or agency of the Company in accordance with Section 2.03 hereof. 


Section 4.03    Reports.    



        (a)   Whether
or not required by the rules and regulations of the SEC, so long as any Notes are outstanding, the Company will furnish to the Holders of Notes, within the time
periods specified in the SEC's rules and regulations: 



        (1)   all
quarterly and annual reports that would be required to be filed with the SEC on Forms 10-Q and 10-K if the Company were required to file such
reports; provided that no quarterly reports will be required with respect to the period ended June 30, 2003 and 



        (2)   all
current reports that would be required to be filed with the SEC on Form 8-K if the Company were required to file such reports. 




        In
addition, following the consummation of the Exchange Offer contemplated by the Registration Rights Agreement, whether or not required by the SEC, the Company will file a copy
of all of the information and reports referred to in clauses (1) and (2) above with the SEC for public availability within the time periods specified in the SEC's rules and regulations
(unless the SEC will not accept such a filing) and make such information available to securities analysts and prospective investors upon request. The Company will at all times comply with TIA
§ 314(a). 


        (b)   For
so long as any Notes remain outstanding, at any time the Company is not required to file the reports required by Section 4.03(a) with the SEC, the Company and
the Guarantors will furnish to the Holders and to securities analysts and prospective investors, upon their request, the information required to be delivered pursuant to Rule 144A(d)(4) under
the Securities Act. 


        (c)   If
MSW has designated any of its Subsidiaries as Unrestricted Subsidiaries, then the quarterly and annual financial information required by this Section 4.03
shall include a reasonably detailed presentation, either on the face of the financial statements or in the footnotes thereto, and in Management's Discussion and Analysis of Financial Condition and
Results of Operations, of the financial condition and results of operations of MSW and its Restricted Subsidiaries separate from the financial condition and results of operations of the Unrestricted
Subsidiaries of MSW. 


Section 4.04    Compliance Certificate.    


        (a)   The
Company and each Guarantor (to the extent that such Guarantor is so required under the TIA) shall deliver to the Trustee, within 120 days after the end of
each fiscal year, an Officers' Certificate stating (i) that in the course of the performance by the signers of their duties as Officers they would normally have knowledge of any action or event
that would cause a Default under this Indenture and (ii) as to each such Officer, that to the best of such Officer's knowledge, no Default under this Indenture has occurred during the preceding
fiscal year and no Default exists as of the date of such Officers' Certificate (or if a Default has occurred during the preceding fiscal year or exists as of the date of such Officers' Certificate,
describing all such Defaults and what action the Company is taking or proposes to take with respect thereto). 


        (b)   So
long as not contrary to the then current recommendations of the American Institute of Certified Public Accountants, the Company will use reasonable best efforts to
obtain and deliver with 


39





 



the
year-end financial statements delivered pursuant to Section 4.03(a) above, a written statement of the Company's independent auditors (who shall be a firm of established national
reputation) that in making the examination necessary for certification of such financial statements, nothing has come to their attention that would lead them to believe that the Company has violated
any accounting provisions of Article 4 or Article 5 hereof or, if any such violation has occurred, specifying the nature and period of existence thereof, it being understood that such
accountants shall not be liable directly or indirectly to any Person for any failure to obtain knowledge of any such violation. 



        (c)   So
long as any of the Notes are outstanding, the Company will deliver to the Trustee, forthwith upon any Officer becoming aware of any Default or Event of Default, an
Officers' Certificate specifying such Default or Event of Default and what action the Company is taking or proposes to take with respect thereto. 


Section 4.05    Taxes.    


        The
Company will pay, and will cause each of its Subsidiaries to pay, prior to delinquency, all material taxes, assessments, and governmental levies except such as are contested in good
faith and by appropriate proceedings or where the failure to effect such payment is not adverse in any material respect to the Holders of the Notes. 


Section 4.06    Stay, Extension and Usury Laws.    


        The
Company and each of the Guarantors covenants (to the extent that it may lawfully do so) that it will not at any time insist upon, plead, or in any manner whatsoever claim or take the
benefit or advantage of, any stay, extension or usury law wherever enacted, now or at any time hereafter in force,
that may affect the covenants or the performance of this Indenture; and the Company and each of the Guarantors (to the extent that it may lawfully do so) hereby expressly waives all benefit or
advantage of any such law, and covenants that it will not, by resort to any such law, hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the
execution of every such power as though no such law has been enacted. 


Section 4.07    Restricted Payments.    


        (a)   MSW
shall not, and shall not permit any of its Restricted Subsidiaries to, directly or indirectly: 



        (1)   declare
or pay any dividend or make any other payment or distribution on account of MSW's or any of its Restricted Subsidiaries' Equity Interests (including, without
limitation, any payment in connection with any merger or consolidation involving MSW or any of its Restricted Subsidiaries and repayments of any capital contribution loan made by a member of MSW) or
to the direct or indirect holders of MSW's or any of its Restricted Subsidiaries' Equity Interests in their capacity as such (other than dividends or distributions payable in Equity Interests (other
than Disqualified Stock) of MSW or to MSW or a Restricted Subsidiary of MSW); 


        (2)   purchase,
redeem or otherwise acquire or retire for value (including, without limitation, in connection with any merger or consolidation involving MSW) any Equity
Interests of MSW or any direct or indirect parent of MSW; 


        (3)   make
any payment on or with respect to, or purchase, redeem, defease or otherwise acquire or retire for value any Indebtedness that is subordinated to the Notes or the
Note Guarantees, except a payment of interest or principal at the Stated Maturity thereof; or 


        (4)   make
any Restricted Investment (all such payments and other actions set forth in these clauses (1) through (4) above being collectively referred to as
"Restricted Payments"), 



40





 





unless,
at the time of and after giving effect to such Restricted Payment: 



        (1)   no
Default or Event of Default has occurred and is continuing or would occur as a consequence of such Restricted Payment; 


        (2)   the
Issuers are not then required to make an ARC Transaction Offer pursuant to Section 4.10 which they have not yet consummated; and 



        (3)   MSW
would, at the time of such Restricted Payment, have been permitted to incur at least $1.00 of additional Indebtedness pursuant to (a) the Proportionate
Consolidated Interest Coverage Ratio test and (b) the projected Proportionate Consolidated Interest Coverage Ratio test set forth in Section 4.09(a). 




        MSW's
Board of Directors shall determine on a basis consistent with the projections most recently approved by MSW's Board of Directors in good faith whether MSW's projected Proportionate
Consolidated Interest Coverage Ratio for the relevant period is greater than 2.0 to 1.0. Not later than the date of making such Restricted Payment, the Issuers shall deliver to the Trustee an
Officers' Certificate stating that the making of such Restricted Payment is permitted and setting forth the basis upon which the Proportionate Consolidated Interest Coverage Ratio tests were computed;  provided that such Officers' Certificate need not include any projections, including the amount by which the projected Proportionate Consolidated
Interest Coverage Ratio exceeds 2.0 to 1.0. 


        (b)   So
long as no Default (or, in the case of clause (5) below, so long as no Event of Default based on the failure to pay principal on the Notes) has occurred and is
continuing or would be caused thereby, the provisions of Section 4.07(a) will not prohibit: 



        (1)   the
payment of any dividend or distribution within 60 days after the date of declaration of the dividend or distribution, if at the date of declaration the
dividend or distribution payment would have complied with the provisions of this Indenture; 


        (2)   the
redemption, repurchase, retirement, defeasance or other acquisition of any subordinated Indebtedness of MSW or any Guarantor or of any Equity Interests of MSW in
exchange for, or out of the net cash proceeds of the substantially concurrent sale (other than to any Subsidiary of MSW) of, Equity Interests of MSW (other than Disqualified Stock) or out of the net
proceeds of substantially concurrent capital contributions made to MSW; provided that the amount of any such net cash proceeds that are utilized for any
such redemption, defeasance or other acquisition will be excluded from clause (7) of this paragraph; 


        (3)   the
defeasance, redemption, repurchase or other acquisition of subordinated Indebtedness of MSW or any Guarantor with the net cash proceeds from an incurrence of
Permitted Refinancing Indebtedness; 


        (4)   the
payment of any dividend by a Restricted Subsidiary of MSW to the holders of its Equity Interests on a pro rata basis; 



        (5)   so
long as MSW is a limited liability company that is not treated as an association taxable as a corporation for federal income tax purposes, distributions to members of
MSW (or the owners of such members) in an amount not to exceed the Tax Accrual Amount for such period and all prior periods; provided that no distribution shall be made unless MSW would, at the time
of such distribution, have been permitted to incur at least $1.00 of additional Indebtedness pursuant to Section 4.09(a)(i) and (ii) of this Indenture; 


        (6)   the
repurchase, redemption or other acquisition or retirement for value of any Equity Interests of MSW or any Restricted Subsidiary of MSW held by any member of MSW's
(or any of its Restricted Subsidiaries') current or former management or any of their permitted transferees pursuant to any management equity subscription agreement, stock option agreement or similar 



41





 




agreement;
provided that the aggregate price paid for all such repurchased, redeemed, acquired or retired Equity Interests may not exceed
$2.0 million in any twelve-month period (with amounts not being used in any twelve-month period being carried-forward to the next twelve-month period;  provided, that the aggregate price paid in any
twelve-month period may not exceed $10.0 million); 



        (7)   Restricted
Payments by MSW or its Restricted Subsidiaries in an amount not to exceed the cumulative net cash proceeds it receives from (i) the sale of Equity
Interests (other than Disqualified Stock), (ii) capital contributions and (iii) cash distributions from any of its Unrestricted Subsidiaries; 


        (8)   payment
of interest on and repayment by MSW of any capital contribution loan made by a member of MSW to MSW or the payment by MSW of preferred returns on, or the
redemption by MSW of, preferred interest in MSW, in each case subject to and in accordance with the terms of MSW's Amended and Restated Limited Liability Company Agreement; 



        (9)   payments
to Affiliates or Duke/UAE Ref-Fuel in consideration for the assumption of Duke Capital Corporation's obligations under the Essex Support Agreement; 


        (10) capital
contribution and capital contribution loans by MSW or any of its Subsidiaries to Duke/UAE Ref-Fuel up to an aggregate amount of $20.0 million
outstanding at any one time; and 


        (11) other
Restricted Payments not to exceed $15.0 million in the aggregate since the date of this Indenture. 




        The
amount of all Restricted Payments (other than cash) shall be the fair market value on the date of the Restricted Payment of the asset(s) or securities proposed to be transferred or
issued by MSW or such Restricted Subsidiary, as the case may be, pursuant to the Restricted Payment. The fair market value of any assets or securities that are required to be valued by this
Section 4.07 shall be determined in good faith by the Board of Directors whose resolution with respect thereto will be delivered to the Trustee. Not later than the date of making any Restricted
Payment, the Issuers will deliver to the Trustee an Officers' Certificate stating that such Restricted Payment is permitted and setting forth the basis upon which the calculations required by this
Section 4.07 were computed; provided that such Officers' Certificate need not include any projections, including the amount by which the
projected Proportionate Consolidated Interest Coverage Ratio exceeds 2.0 to 1.0. 


        (c)   Notwithstanding
anything contained to the contrary in this Section 4.07, MSW may not make a Restricted Payment with the proceeds of any Indebtedness incurred by
MSW or any of its Restricted Subsidiaries, other than a distribution of proceeds of ARC Acquisition Indebtedness to facilitate the acquisition of additional Capital Stock of Duke/UAE
Ref-Fuel or another direct or indirect ownership interest in ARC. 


Section 4.08    Dividend and Other Payment Restrictions Affecting Subsidiaries.    


        (a)   MSW
shall not, and shall not permit any of its Restricted Subsidiaries to, directly or indirectly, create or permit to exist or become effective any consensual
encumbrance or restriction on the ability of any Restricted Subsidiary to, and MSW will not vote its membership interest so that Duke/UAE Ref-Fuel will create or permit to exist or become
effective any consensual encumbrance or restriction on the ability of Duke UAE/Ref-Fuel to: 



        (1)   pay
dividends or make any other distributions on its Capital Stock to MSW or any of its Restricted Subsidiaries, or with respect to any other interest or participation
in, or measured by, its profits, or pay any Indebtedness owed to MSW or any of its Restricted Subsidiaries; 


        (2)   make
loans or advances to MSW or any of its Restricted Subsidiaries; or 


        (3)   transfer
any of its properties or assets to MSW or any of its Restricted Subsidiaries. 



42





 





        (b)   The
restrictions in Section 4.08(a) shall not apply to encumbrances or restrictions existing under or by reason of: 



        (1)   Agreements
governing Existing Indebtedness; 


        (2)   this
Indenture, the Notes and the Note Guarantees; 


        (3)   applicable
law; 


        (4)   any
instrument governing Indebtedness or Capital Stock of a Person acquired by MSW or any of its Restricted Subsidiaries as in effect at the time of such acquisition
(except to the extent such Indebtedness or Capital Stock was incurred in connection with or in contemplation of such acquisition), which encumbrance or restriction is not applicable to any Person, or
the properties or assets of any Person, other than the Person, or the property or assets of the Person, so acquired, provided that, in the case of
Indebtedness incurred in connection with the acquisition, such Indebtedness of such acquired Person was permitted by the terms of this Indenture to be incurred by MSW and its Restricted Subsidiaries; 


        (5)   customary
non-assignment provisions in leases and other agreements entered into in connection with the acquisition of Duke Hudson or Duke Erie or in the
ordinary course of business; 


        (6)   any
agreement for the sale or other disposition of a Restricted Subsidiary that restricts distributions by that Restricted Subsidiary pending its sale or other
disposition; 


        (7)   Permitted
Refinancing Indebtedness, provided that the restrictions contained in the agreements governing such Permitted
Refinancing Indebtedness are no more restrictive, taken as a whole, than those contained in the agreements governing the Indebtedness being refinanced; 


        (8)   Liens
securing Indebtedness otherwise permitted to be incurred under this Indenture pursuant to Section 4.12 that limit the right of the debtor to dispose of the
assets subject to such Liens; 


        (9)   restrictions
on cash or other deposits or net worth imposed by customers under contracts entered into in the ordinary course of business; 


        (10) any
restrictions arising under the terms of the Duke Essex Side Agreement (as in effect on the date of this Indenture); and 


        (11) in
the case of Duke/UAE Ref-Fuel, any consensual encumbrances or other restrictions contained in the Amended and Restated Limited Liability Company
Agreement of Duke/UAE Ref-Fuel as in effect on the date of this Indenture. 




Section 4.09    Incurrence of Indebtedness and Issuance of Preferred Equity.    


        (a)   MSW
shall not, and shall not permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur, issue, assume, guarantee or otherwise become directly
or indirectly liable, contingently or otherwise, with respect to (collectively, "incur") any Indebtedness (including Acquired Debt), and the Issuers
shall not issue any Disqualified Stock and shall not permit any of their Restricted Subsidiaries to issue any shares of preferred equity; provided,
however, that the Issuers may incur Indebtedness (including Acquired Debt) or issue Disqualified Stock, and the Issuers' Restricted Subsidiaries may incur Indebtedness or issue
preferred stock if, (i) the Proportionate Consolidated Interest Coverage Ratio for the Issuers' most recently ended four full fiscal quarters for which internal financial statements are
available immediately preceding the date on which such additional Indebtedness is incurred or such Disqualified Stock or preferred equity is issued would have been at least 2.0 to 1.0, determined on a
pro forma basis (including a pro forma application of the net proceeds therefrom), as if the additional Indebtedness had been incurred or the Disqualified Stock or preferred equity had 


43





 



been
issued, as the case may be, at the beginning of such four-quarter period; (ii) the projected Proportionate Consolidated Interest Coverage Ratio for the Issuers' four full
fiscal quarters commencing with the first full fiscal quarter after the date of the proposed incurrence of Indebtedness or issuance of Disqualified Stock or preferred equity would be at least 2.0 to
1.0; and (iii) if the Indebtedness to be incurred constitutes Indebtedness that is pari passu with the Notes, the Issuers deliver to the Trustee
written confirmation from S&P that the issuance of such Indebtedness will not result in a downgrade of the then current ratings on the Notes. 



        MSW's
Board of Directors shall determine on a basis consistent with the projections most recently approved by MSW's Board of Directors in good faith whether MSW's projected Proportionate
Consolidated Interest Coverage Ratio for the relevant period is greater than 2.0 to 1.0. Not later than the date of incurring such additional Indebtedness or issuing such Disqualified Stock or
preferred equity, the Issuers shall deliver to the Trustee an Officers' Certificate stating that the incurrence of such additional Indebtedness or issuance of Disqualified Stock or preferred equity is
permitted and setting forth the basis upon which the Proportionate Consolidated Interest Coverage Ratio tests were computed; provided that such
Officers' Certificate need not include any projections, including the amount by which the projected Proportionate Consolidated Interest Coverage Ratio exceeds 2.0 to 1.0. 


        (b)   The
provisions of Section 4.09(a) shall not prohibit the incurrence of any of the following items of Indebtedness (collectively,
"Permitted Debt"): 



        (1)   the
incurrence by MSW and its Restricted Subsidiaries of the Existing Indebtedness; 


        (2)   the
incurrence by MSW of any Indebtedness to its members in respect of capital contribution loans or any other loans from the members of MSW to MSW contemplated by the
Amended and Restated Limited Liability Company Agreement of MSW as in effect on the date of this Indenture; 


        (3)   the
incurrence by the Issuers and the Guarantors of Indebtedness represented by the Notes and the related Note Guarantees to be issued on the date of this Indenture and
the Exchange Notes and the related Note Guarantees to be issued pursuant to the Registration Rights Agreement and any future Note Guarantee delivered by a Restricted Subsidiary; 


        (4)   the
incurrence by MSW or any of its Restricted Subsidiaries of Permitted Refinancing Indebtedness in exchange for, or the net proceeds of which are used to refund,
refinance or replace Indebtedness (other than intercompany Indebtedness) that was permitted by this Indenture to be incurred under Section 4.09(a) or clauses (b)(1), (3), (9)(c), (9)(d) or
(10) of this Section 4.09(b); 


        (5)   the
incurrence by MSW or any of its Restricted Subsidiaries of intercompany Indebtedness between or among MSW and any of its Restricted Subsidiaries;  provided, however, that: 



        (a)   if
an Issuer or any Guarantor is the obligor on such Indebtedness, such Indebtedness must be expressly subordinated to the prior payment in full in cash of all
Obligations with respect to the Notes, in the case of an Issuer, or the Note Guarantee, in the case of a Guarantor; and 


        (b)   (i) any
subsequent issuance or transfer of Equity Interests that results in any such Indebtedness being held by a Person other than MSW or a Restricted Subsidiary
of MSW and (ii) any sale or other transfer of any such Indebtedness to a Person that is not either MSW or a Restricted Subsidiary of MSW; shall be deemed, in each case, to constitute an
incurrence of such Indebtedness by MSW or such Restricted Subsidiary, as the case may be, that was not permitted by this Section 4.09(b)(5); 




44













  



        (6)   the
incurrence by MSW or any of its Restricted Subsidiaries of Hedging Obligations that are incurred for the purpose of fixing or hedging interest rate risk with respect
to any floating rate Indebtedness that is permitted by the terms of this Indenture to be outstanding; 



        (7)   the
guarantee by the Issuers or any of the Guarantors of Indebtedness of the Issuers or a Restricted Subsidiary of the Issuers that was permitted to be incurred by
another provision of this Section 4.09; 


        (8)   the
accrual of interest, the accretion or amortization of original issue discount, the payment of interest on any Indebtedness in the form of additional Indebtedness
with the same terms, and the payment of dividends on Disqualified Stock in the form of additional shares of the same class of Disqualified Stock will not be deemed to be an incurrence of Indebtedness
or an issuance of Disqualified Stock for purposes of this covenant; provided, in each such case, that the amount thereof is included in Consolidated
Interest Expense of the Issuers as accrued; 


        (9)   in
the event that ARC becomes a Subsidiary of MSW or MSW and its Affiliates control 100% of the membership interests in Duke/UAE Ref-Fuel and either MSW
incurs ARC Acquisition Indebtedness or Duke/UAE Ref-Fuel becomes a subsidiary of MSW, 



        (a)   the
incurrence of Indebtedness under the ARC Credit Facility in an aggregate principal amount at any one time outstanding under this clause (9)(a)(with letters of
credit being deemed to have a principal amount equal to the maximum potential liability of ARC and its Subsidiaries thereunder) not to exceed $75.0 million; 


        (b)   the
incurrence by ARC and its Restricted Subsidiaries of Purchase Money Indebtedness not exceeding the cost of the property being financed with such Indebtedness and
that does not extend to any property other than the property being financed permitted to be incurred under the ARC Indenture; 


        (c)   the
incurrence by ARC and its Restricted Subsidiaries of Indebtedness incurred in connection with any modification of any of the ARC Operating Facilities required in
connection with compliance with applicable laws permitted to be incurred under the ARC Indenture; and 


        (d)   the
incurrence by ARC and its Restricted Subsidiaries of Non-Recourse Debt permitted under the ARC Indenture and incurred in connection with any new
acquisition or development with respect to activities not prohibited by the ARC Indenture; and 




        (10) the
incurrence by MSW or any of its Restricted Subsidiaries of additional Indebtedness in an aggregate principal amount (or accreted value, as applicable) at any time
outstanding, including all Permitted Refinancing Indebtedness incurred to refund, refinance or replace any Indebtedness incurred pursuant to this Section 4.09(b)(10), not to exceed
$30.0 million. 




        The
Issuers shall not incur any Indebtedness (including Permitted Debt) that is contractually subordinated in right of payment to any other Indebtedness of the Issuers unless such
Indebtedness is also contractually subordinated in right of payment to the Notes on substantially identical terms; provided, however, that no
Indebtedness of the Issuers shall be deemed to be contractually subordinated in right of payment to any other Indebtedness of the Issuers solely by virtue of being unsecured. 



        For
purposes of determining compliance with this Section 4.09, in the event that an item of proposed Indebtedness meets the criteria of more than one of the categories of
Permitted Debt described in clauses (1) through (10) above or is entitled to be incurred pursuant to Section 4.09(a), the Issuers shall be permitted to classify such item of
Indebtedness on the date of its incurrence, or later reclassify all or a portion of such item of Indebtedness, in any manner that complies with this Section 4.09. 


45





 



        For
purposes of determining compliance with this Section 4.09, if ARC becomes a Subsidiary of MSW or MSW and its Affiliates control 100% of the membership interests in Duke/UAE
Ref-Fuel and either MSW incurs ARC Acquisition Indebtedness or Duke/UAE Ref-Fuel becomes a Subsidiary of MSW, the Indebtedness of ARC and its Subsidiaries outstanding at the
time it becomes subject to this Section 4.09 shall be deemed to be Existing Indebtedness of MSW and its Restricted Subsidiaries. 


Section 4.10    Asset Sales.    


        (a)   MSW
shall not, and shall not permit any of its Restricted Subsidiaries to, consummate an Asset Sale. 


        (b)   Any
distribution of any net proceeds received by MSW or its Restricted Subsidiaries from: 



        (1)   an
issuance of any debt or equity securities or incurrence of other Indebtedness by Duke/UAE Ref-Fuel or any of its Subsidiaries; and 


        (2)   the
consummation of an ARC Asset Sale by Duke/UAE Ref-Fuel or any of its Subsidiaries 




will
constitute "Excess Proceeds". Within 30 days of the date when the aggregate amount of Excess Proceeds exceeds $20.0 million, the
Issuers will make an ARC Transaction Offer to all Holders of notes and all holders of other Indebtedness that is pari passu with the Notes containing
provisions similar to those set forth in this Indenture with respect to offers to purchase or redeem with the proceeds of sales of assets to purchase the maximum principal amount of notes and such
other pari passu Indebtedness that may be purchased out of the Excess Proceeds. The offer price in any ARC Transaction Offer will be equal to 100% of
principal amount plus accrued and unpaid interest and Additional Interest, if any, to the date of purchase, and will be payable in cash. If any Excess Proceeds remain after consummation of an ARC
Transaction Offer, the Issuers may use those Excess Proceeds for any purpose not otherwise prohibited by this Indenture. If the aggregate principal amount of notes and other  pari passu Indebtedness
tendered into such ARC Transaction Offer exceeds the amount of Excess Proceeds, the Trustee will select the Notes and such other  pari passu Indebtedness to be purchased on a pro rata basis. Upon
completion of each ARC Transaction Offer, the amount of Excess Proceeds will be reset
at zero. 


        The
Issuers 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 each repurchase of Notes pursuant to an ARC Transaction Offer. To the extent that the provisions of any securities laws or regulations conflict with
the provisions of Sections 3.09 or 4.10 of this Indenture, the Issuers shall comply with the applicable securities laws and regulations and will not be deemed to have breached their obligations under
those provisions of this Indenture by virtue of such conflict. 



        (c)   Whether
MSW or any of its Restricted Subsidiaries has received net proceeds from the events described in Section 4.10(b)(1) and (2), and the amount of any such
net proceeds, shall be determined by MSW's Board of Directors in good faith. 


Section 4.11    Transactions with Affiliates.    


        (a)   MSW
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 (each an "Affiliate Transaction"), unless: 



        (1)   such
Affiliate Transaction is on terms that are no less favorable to MSW or the relevant Restricted Subsidiary than those that would have been obtained in a comparable
transaction by MSW or such Restricted Subsidiary with an unrelated Person; and 



46





 

        (2)   MSW
delivers to the Trustee: 



        (A)  with
respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $2.0 million, a resolution of
the Board of Directors set forth in an Officers' Certificate certifying that such Affiliate Transaction complies with clause (1) of this Section 4.11(a) and that such Affiliate
Transaction has been approved by a majority of the disinterested members of the Board of Directors of MSW; and 



        (B)  with
respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $10.0 million, an opinion as
to the fairness to MSW of such Affiliate Transaction from a financial point of view issued by an accounting, appraisal or investment banking firm of national standing. 





        (b)   The
following items will not be deemed to be Affiliate Transactions and, therefore, will not be subject to the provisions of Section 4.11(a): 



        (1)   any
employment agreement entered into by MSW or any of its Restricted Subsidiaries in the ordinary course of business of MSW or such Restricted Subsidiary; 


        (2)   transactions
between or among MSW and/or its Restricted Subsidiaries; 


        (3)   transactions
with a Person that is an Affiliate of MSW solely because MSW owns an Equity Interest in, or controls, such Person; 


        (4)   payment
of reasonable directors fees to Persons who are not otherwise Affiliates of the Issuers; 


        (5)   sales
of Equity Interests of MSW (other than Disqualified Stock) to Affiliates of MSW; 


        (6)   Restricted
Payments that are permitted by Section 4.07 hereof; 


        (7)   Reimbursements
of any drawings and related interest and fees made to Affiliates by MSW or its Restricted Subsidiaries with respect to letters of credit, corporate
guarantees or other agreements furnished on behalf of MSW or its Restricted Subsidiaries by such Affiliates; 



        (8)   payment
of reasonable administrative services fees, and reimbursement of related expenses, by MSW to its members or their Affiliates, to the extent a majority of the
representatives to MSW's Board of Directors appointed by the disinterested member(s) of MSW approves such arrangements and determines that such administrative services are necessary and must be
obtained either by outsourcing to a third party or by hiring additional employees to perform such services; 


        (9)   the
provision by Credit Suisse Boston LLC or its Affiliates of investment banking or other services, if such arrangements are approved by a majority of the
representatives appointed by the disinterested member(s) of MSW; 


        (10) the
provision by American International Group, Inc. or its Affiliates of insurance and surety bond services, if such arrangements are approved by a majority of
the representatives appointed by the disinterested member(s) of MSW; and 


        (11) the
acquisition of additional membership interests in Duke/UAE Ref-Fuel. 




Section 4.12    Liens.    



        MSW
shall not, and shall not permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur, assume or suffer to exist any Lien of any kind on any asset now owned or
hereafter acquired, except Permitted Liens. 


47





 



Section 4.13    Line of Business.    


        The
Issuers shall not, and shall not permit any of their Restricted Subsidiaries to, hold any material assets, become liable for any material obligations or engage in any significant
business activities other than holding the Capital Stock, directly or indirectly, of Duke/UAE Ref-Fuel or any entity that succeeds to all or part of Duke/UAE Ref-Fuel's
ownership interest in ARC; provided that (i) MSW may incur any Indebtedness permitted to be incurred by this Indenture if the net proceeds of
such Indebtedness are received by MSW or one or more of MSW's Restricted Subsidiaries and MSW Finance may be a co-obligor or guarantor with respect to such Indebtedness if MSW is a primary
obligor of such Indebtedness and (ii) the Issuers and their Restricted Subsidiaries may own Unrestricted Subsidiaries in accordance with the applicable provisions of this Indenture, and the
Unrestricted Subsidiaries will be free to engage in any line of business. 


Section 4.14    Corporate Existence.    


        Subject
to Article 5 hereof, MSW shall do or cause to be done all things necessary to preserve and keep in full force and effect: 



        (1)   its
limited liability company existence, and the corporate, partnership or other existence of each of its Restricted Subsidiaries, in accordance with the respective
organizational documents (as the same may be amended from time to time) of MSW or any such Restricted Subsidiary; and 



        (2)   the
rights (charter and statutory), licenses and franchises of MSW and its Restricted Subsidiaries; provided, however,
that MSW shall not be required to preserve any such right, license or franchise, or the corporate, partnership or other existence of any of its Restricted Subsidiaries, if the Board of Directors shall
determine that the preservation thereof is no longer desirable in the conduct of the business of MSW and its Restricted Subsidiaries, taken as a whole, and that the loss thereof is not adverse in any
material respect to the Holders of the Notes. 




Section 4.15    Offer to Repurchase Upon Change of Control.    



        (a)   Upon
the occurrence of a Change of Control, the Issuers shall make an offer (a "Change of Control Offer") to each Holder
to repurchase all or any part (equal to $1,000 or an integral multiple of $1,000) of each Holder's Notes at a purchase price equal to 101% of the aggregate principal amount thereof plus accrued and
unpaid interest and Additional Interest on the Notes repurchased, if any, to (but not including) the date of purchase the "Change of Control Payment").
Within 30 days following any Change of Control, the Issuers shall mail a notice to each Holder describing the transaction or transactions that constitute the Change of Control and stating: 



        (1)   that
the Change of Control Offer is being made pursuant to this Section 4.15 and that all Notes tendered will be accepted for payment; 


        (2)   the
purchase price and the purchase date, which shall be no earlier than 30 days and no later than 60 days from the date such notice is mailed (the  "Change of Control Payment Date"); 


        (3)   that
any Note not tendered will continue to accrue interest; 


        (4)   that,
unless the Issuers default in the payment of the Change of Control Payment, all Notes accepted for payment pursuant to the Change of Control Offer will cease to
accrue interest after the Change of Control Payment Date; 


        (5)   that
Holders electing to have any Notes purchased pursuant to a Change of Control Offer will be required to surrender the Notes, with the form entitled "Option of Holder
to Elect Purchase" on the reverse of the Notes completed, to the Paying Agent at the address specified in the notice prior to the close of business on the third Business Day preceding the Change of
Control Payment Date; 



48





 




        (6)   that
Holders will be entitled to withdraw their election if the Paying Agent receives, not later than the close of business on the second Business Day preceding the
Change of Control Payment Date, a telegram, telex, facsimile transmission or letter setting forth the name of the Holder, the principal amount of Notes delivered for purchase, and a statement that
such Holder is withdrawing his election to have the Notes purchased; and 



        (7)   that
Holders whose Notes are being purchased only in part will be issued new Notes equal in principal amount to the unpurchased portion of the Notes surrendered, which
unpurchased portion must be equal to $1,000 in principal amount or an integral multiple thereof. 




        The
Issuers shall comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws
and regulations are applicable in connection with the repurchase of the Notes as a result of a Change in Control. To the extent that the provisions of any securities laws or regulations conflict with
the provisions of Sections 3.09 or 4.15 of this Indenture, the Issuers shall comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under
Section 3.09 or this Section 4.15 by virtue of such conflict. 


        (b)   On
the Change of Control Payment Date, the Issuers shall, to the extent lawful: 



        (1)   accept
for payment all Notes or portions thereof properly tendered pursuant to the Change of Control Offer; 


        (2)   deposit
with the Paying Agent an amount equal to the Change of Control Payment in respect of all Notes or portions of Notes properly tendered; and 



        (3)   deliver
or cause to be delivered to the Trustee the Notes so accepted together with an Officers' Certificate stating the aggregate principal amount of Notes or portions
of Notes being purchased by the Company. 




        The
Paying Agent will promptly mail to each Holder of Notes properly tendered the Change of Control Payment for such Notes, and the Trustee will promptly authenticate and mail (or cause
to be transferred by book entry) to each Holder a new Note equal in principal amount to any unpurchased portion of the Notes surrendered, if any;  provided that each new Note will be in a principal
amount of $1,000 or an integral multiple thereof. The Issuers shall publicly announce the results of
the Change of Control Offer on or as soon as practicable after the Change of Control Payment Date. 


        (c)   Notwithstanding
anything to the contrary in this Section 4.15, the Issuers shall not be required to make a Change of Control Offer upon a Change of Control if a
third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in this Section 4.15 and Section 3.09 hereof and
purchases all Notes validly tendered and not withdrawn under the Change of Control Offer or Moody's and S&P shall have confirmed their then current ratings of the Issuers following such Change of
Control. 


Section 4.16    Payments for Consent.    



        MSW
shall not, and shall not permit any of its Restricted Subsidiaries to, directly or indirectly, pay or cause to be paid any consideration to or for the benefit of any Holder of Notes
for or as an inducement to any consent, waiver or amendment of any of the terms or provisions of this Indenture or the Notes unless such consideration is offered to be paid and is paid to all Holders
of the Notes that consent, waive or agree to amend in the time frame set forth in the solicitation documents relating to such consent, waiver or agreement. 


Section 4.17    Additional Note Guarantees.    



        If
MSW or any of its Restricted Subsidiaries acquires, creates or obtains control of another Subsidiary after the date of this Indenture, then MSW shall cause that newly acquired,
created or 


49





 



controlled
Subsidiary (other than a Subsidiary that does not constitute a Restricted Subsidiary) to execute a Note Guarantee pursuant to a supplemental indenture in form and substance satisfactory to
the Trustee and deliver an Opinion of Counsel to the Trustee within 90 days of the date on which it was acquired, created or on which MSW obtained control. In the event that MSW and its
Affiliates control 100% of Duke/UAE Ref-Fuel and either MSW incurs ARC Acquisition Indebtedness or Duke/UAE Ref-Fuel becomes a Subsidiary of MSW, then MSW shall cause the
Affiliates that directly hold the Capital Stock of Duke/UAE Ref-Fuel to execute a Note Guarantee pursuant to a supplemental indenture. The form of such Note Guarantee is attached as
Exhibit E hereto. 


Section 4.18    Additional Pledges of Capital Stock.    


        If
MSW or any Guarantor directly acquires, creates or obtains control of another Subsidiary after the date of this Indenture, then MSW or such Guarantor shall pledge the Capital Stock of
that newly acquired, created or controlled Subsidiary held by MSW or such Guarantor, and, if such newly acquired, created or controlled Subsidiary is a Restricted Subsidiary, it shall pledge the
Capital Stock of any Subsidiary held directly by such newly acquired, created or controlled Subsidiary, in each case, as security for the full and final payment and performance of the Obligations of
the Issuers under this Indenture and the Notes, except, that in the event Duke/UAE Ref-Fuel becomes a Restricted Subsidiary, it will not be required to pledge the Capital Stock in ARC to
the extent prohibited by any financing agreement entered into prior to and not in connection with Duke/UAE Ref-Fuel becoming a Restricted Subsidiary. In the event that MSW and its
Affiliates control 100% of Duke UAE/Ref-Fuel and either MSW incurs ARC Acquisition Indebtedness or Duke UAE/Ref Fuel becomes a Subsidiary of MSW, such Affiliate shall pledge the Capital
Stock of Duke UAE/Ref-Fuel that it directly holds. MSW, the Guarantors and such newly acquired, created or controlled Subsidiary shall execute a pledge agreement with the collateral agent
and deliver an opinion of counsel satisfactory to the collateral agent within 90 days of the date on which it was acquired, created or controlled. 


Section 4.19    Distributions From Duke/UAE Ref-Fuel.    


        In
the event that MSW and its Affiliates control 100% of Duke UAE/Ref-Fuel and either MSW incurs ARC Acquisition Indebtedness or Duke UAE/Ref Fuel becomes a Subsidiary of
MSW, MSW shall either: 



        (a)   cause
Duke/UAE Ref-Fuel (or any other Affiliate succeeding to Duke/UAE Ref-Fuel's interest in ARC) to distribute all distributions received by
Duke UAE Ref-Fuel, after payment of any operating or similar expenses then due and payable or estimated to be due and payable within the next three months, with respect to its interest in
ARC to MSW for application as directed by MSW pursuant to Section 4.1.2 of the Deposit Agreement; or 


        (b)   cause
Duke UAE/Ref-Fuel to enter into a deposit agreement, having the same terms and conditions as the Deposit Agreement, including, without limitation,
requiring Duke/UAE Ref-Fuel to: 



        (1)   establish
accounts identical to the "Accounts" set forth in Section 2.1 of the Deposit Agreement; 


        (2)   deposit
all dividends, distributions and other amounts received by Duke/UAE Ref-Fuel on account of its interests in its Subsidiaries, including payments on
loans made by Duke UAE/Ref-Fuel to its Subsidiaries, into such accounts; and 


        (3)   distribute
all funds held in such accounts pursuant to waterfall levels identical to the "Waterfall Levels" set forth in Section 4.1.2 of the Deposit Agreement; 





provided that the "Operating Account" in such deposit agreement shall include operating and similar expenses of MSW and the other Affiliates holding an
interest in Duke UAE/Ref-Fuel and the MSW 


50





 

Distribution
Account shall hold amounts to be distributed to MSW and all other members of Duke/UAE Ref-Fuel. 


Section 4.20    Designation of Restricted and Unrestricted Subsidiaries.    



        The
Board of Directors of MSW may designate any Restricted Subsidiary (other than MSW Finance, Duke Hudson or, upon acquisition, Duke Erie, or any Subsidiary that holds the Capital Stock
of Duke/UAE Ref-Fuel, ARC or any of their Subsidiaries or any successor to any of them) to be an Unrestricted Subsidiary if that designation would not cause a Default. If a Restricted
Subsidiary is designated as an Unrestricted Subsidiary, the aggregate fair market value of all outstanding Investments owned by MSW and its Restricted Subsidiaries in the Subsidiary properly
designated will be deemed to be an Investment made as of the time of the designation. That
designation will only be permitted if the Investment would be permitted at that time and if the Restricted Subsidiary otherwise meets the definition of an Unrestricted Subsidiary. The Board of
Directors of MSW may redesignate any Unrestricted Subsidiary to be a Restricted Subsidiary if the redesignation would not cause a Default. 


ARTICLE 5.

Section 5.01    Merger, Consolidation, or Sale of Assets.    


        MSW
shall not, directly or indirectly, (a) consolidate or merge with or into another Person (whether or not MSW is the surviving corporation), or (b) sell, assign,
transfer, convey or otherwise dispose of all or substantially all of the properties or assets of MSW and its Restricted Subsidiaries taken as a whole, in one or more related transactions, to another
Person; unless: 



        (1)   either:




        (A)  MSW
is the surviving entity; or 


        (B)  the
Person formed by or surviving any such consolidation or merger (if other than MSW) or to which such sale, assignment, transfer, conveyance or other disposition has
been made is a corporation or limited liability company organized or existing under the laws of the United States, any state of the United States or the District of Columbia; 




        (2)   the
Person formed by or surviving any such consolidation or merger (if other than MSW) or the Person to which such sale, assignment, transfer, conveyance or other
disposition shall have been made assumes all the obligations of MSW under the Notes, this Indenture, the Registration Rights Agreement, the Deposit Agreement and the Pledge Agreement pursuant to
agreements reasonably satisfactory to the Trustee; 


        (3)   immediately
after such transaction, no Default or Event of Default exists; and 


        (4)   MSW
or the Person formed by or surviving any such consolidation or merger (if other than MSW), or to which such sale, assignment, transfer, conveyance or other
disposition has been made would, on the date of such transaction after giving pro forma effect thereto and any related financing transactions as if the same had occurred at the beginning of the
applicable four-quarter period, either (A) be permitted to incur at least $1.00 of additional Indebtedness pursuant to the historical Proportionate Consolidated Interest Coverage
Ratio test set forth in Section 4.09(a) hereof or (B) have a higher ratio of Consolidated Cash Flow to Consolidated Interest Expense (including for this purpose, the components of the
Proportionate Consolidated Cash Flow for MSW for the applicable period) determined on a basis consistent with this Indenture (whether or not greater than 2.0 to 1.0) than the Proportionate
Consolidated Interest Coverage Ratio for MSW for the same period on a stand-alone basis without giving effect to such merger or consolidation or other applicable transaction.

Section 5.01 shall not apply to a sale, assignment, transfer, conveyance or other disposition of assets between or among the Issuers and any of the Guarantors. 



        Notwithstanding
the foregoing, MSW shall be permitted to reorganize as a corporation in accordance with the terms of this Indenture,  provided that MSW shall have delivered to the Trustee an opinion of counsel in the
United States reasonably acceptable to the Trustee confirming that
such reorganization is not adverse to Holders of the Notes (it being recognized that such reorganization shall not be deemed adverse to the Holders of the Notes solely because (i) of the
accrual of deferred tax liabilities resulting from such reorganization or (ii) the successor or surviving corporation (a) is subject to income tax as a corporate entity or (b) is
considered to be an "includible corporation" of an affiliated group of corporations within the meaning of the Code or any similar state or local law). 


Section 5.02    Successor Corporation Substituted.    


        Upon
any consolidation or merger, or any sale, assignment, transfer, lease, conveyance or other disposition of all or substantially all of the assets of MSW in a transaction that is
subject to, and that complies with the provisions of, Section 5.01 hereof, the successor corporation formed by such consolidation or into or with which MSW is merged or to which such sale,
assignment, transfer, lease, conveyance or other disposition is made shall succeed to, and be substituted for (so that from and after the date of such consolidation, merger, sale, lease, conveyance or
other disposition, the provisions of this Indenture referring to "MSW" shall refer instead to the successor entity and not to MSW), and may exercise every right and power of MSW under this Indenture
with the same effect as if such successor Person had been named as MSW herein; provided, however, that MSW shall not be relieved from the obligation to
pay the principal of and interest on the Notes except in the case of a sale of all of the Company's assets in a transaction that is subject to, and that complies with the provisions of,
Section 5.01 hereof.

        and

Section 6.02    Acceleration.    


        In
the case of an Event of Default specified in clause (11) or (12) of Section 6.01 hereof, all outstanding Notes will become due and payable immediately without
further action or notice. If any other Event of Default 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 immediately. 


        Upon
any such declaration, the Notes shall become due and payable immediately. Notwithstanding the foregoing, if an Event of Default specified in clause (11) or (12) of
Section 6.01 hereof occurs all outstanding Notes shall be due and payable immediately without further action or notice. The Holders of a majority in aggregate principal amount of the then
outstanding Notes by written notice to the Trustee may on behalf of all of the Holders rescind an acceleration and its consequences if the rescission would not conflict with any judgment or decree and
if all existing Events of Default (except nonpayment of principal, interest or premium that has become due solely because of the acceleration) have been cured or waived. 


Section 6.03    Other Remedies.    


        If
an Event of Default occurs and is continuing, the Trustee may pursue any available remedy to collect the payment of principal, premium and Additional Interest, if any, and interest on
the Notes or to enforce the performance of any provision of the Notes or this Indenture. 


        The
Trustee may maintain a proceeding even if it does not possess any of the Notes or does not produce any of them in the proceeding. A delay or omission by the Trustee or any Holder of
a Note in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of or acquiescence in the Event of Default. All remedies are
cumulative to the extent permitted by law. 


Section 6.04    Waiver of Past Defaults.    


        Holders
of not less than a majority in aggregate principal amount of the then outstanding Notes by notice to the Trustee may on behalf of the Holders of all of the Notes waive an
existing Default or Event of Default and its consequences hereunder, except a continuing Default or Event of Default in the payment of the principal of, premium and Additional Interest, if any, or
interest on, the Notes (including in connection with an offer to purchase); provided, however, that the Holders of a majority in aggregate principal
amount of the then outstanding Notes may rescind an acceleration and its consequences, including any related payment default that resulted from such acceleration. Upon any such waiver, such Default
shall cease to exist, and any Event of Default arising therefrom shall be 


54





 

deemed
to have been cured for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other Default or impair any right consequent thereon. 


Section 6.05    Control by Majority.    


        Holders
of a majority in principal amount of the then outstanding Notes may direct the time, method and place of conducting any proceeding for exercising any remedy available to the
Trustee or exercising any trust or power conferred on it. However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture that the Trustee determines may be unduly
prejudicial to the rights of other Holders of Notes or that may involve the Trustee in personal liability. 


Section 6.06    Limitation on Suits.    


        A
Holder of a Note may pursue a remedy with respect to this Indenture or the Notes only if: 



        (1)   the
Holder of a Note gives to the Trustee written notice of a continuing Event of Default; 


        (2)   the
Holders of at least 25% in principal amount of the then outstanding Notes make a written request to the Trustee to pursue the remedy; 



        (3)   such
Holder of a Note or Holders of Notes offer and, if requested, provide to the Trustee indemnity satisfactory to the Trustee against any loss, liability or expense; 


        (4)   the
Trustee does not comply with the request within 60 days after receipt of the request and the offer and, if requested, the provision of indemnity; and 


        (5)   during
such 60-day period the Holders of a majority in principal amount of the then outstanding Notes do not give the Trustee a direction inconsistent with
the request. 




        A
Holder of a Note may not use this Indenture to prejudice the rights of another Holder of a Note or to obtain a preference or priority over another Holder of a Note. 


Section 6.07    Rights of Holders of Notes to Receive Payment.    


        Notwithstanding
any other provision of this Indenture, the right of any Holder to receive payment of principal, premium and Additional Interest, if any, and interest on the Note, on or
after the respective due dates expressed in the Note (including in connection with an ARC Transaction Offer or Change of Control Offer), or to bring suit for the enforcement of any such payment on or
after such respective dates, shall not be impaired or affected without the consent of such Holder; provided that a Holder shall not have the right to
institute any such suit for the enforcement of payment if and to the extent that the institution or prosecution thereof or the entry of judgment therein would, under applicable law, result in the
surrender, impairment, waiver or loss of the Lien of this Indenture upon any property subject to such Lien. 


Section 6.08    Collection Suit by Trustee.    


        If
an Event of Default specified in Section 6.01(1) or (2) occurs and is continuing, the Trustee is authorized to recover judgment in its own name and as trustee of an
express trust against the Company for the whole amount of principal of, premium and Additional Interest, if any, and interest remaining unpaid on the Notes and interest on overdue principal and, to
the extent lawful, interest and such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of
the Trustee, its agents and counsel. 


Section 6.09    Trustee May File Proofs of Claim.    


        The
Trustee is authorized to file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for
the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and the Holders of the Notes allowed in any judicial proceedings relative to the Company (or
any other 


55





 



obligor
upon the Notes), its creditors or its property and shall, as permitted by applicable law, be entitled and empowered to collect, receive and distribute any money or other property payable or
deliverable on any such claims and any custodian in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee, and in the event that the Trustee shall
consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due to it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its
agents and counsel, and any other amounts due the Trustee under Section 7.07 hereof. To the extent that the payment of any such compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.07 hereof out of the estate in any such proceeding, shall be denied for any reason, payment of the same
shall be secured by a Lien on, and shall be paid out of, any and all distributions, dividends, money, securities and other properties that the Holders may be entitled to receive in such proceeding
whether in liquidation or under any plan of reorganization or arrangement or otherwise. Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt
on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder, or to authorize the Trustee to vote in respect of the claim
of any Holder in any such proceeding. 


Section 6.10    Priorities.    


        If
the Trustee collects any money pursuant to this Article 6, it shall pay out the money in the following order: 



         First:    to the Trustee, its agents and attorneys for amounts due under Section 7.07 hereof, including payment of all compensation,
expense and
liabilities incurred, and all advances made, by the Trustee and the costs and expenses of collection; 


         Second:    to Holders of Notes for amounts due and unpaid on the Notes for principal, premium and Additional Interest, if any, and
interest, ratably,
without preference or priority of any kind, according to the amounts due and payable on the Notes for principal, premium and Additional Interest, if any and interest, respectively; and 


         Third:    to the Company or to such party as a court of competent jurisdiction shall direct. 




        The
Trustee may fix a record date and payment date for any payment to Holders of Notes pursuant to this Section 6.10. 


Section 6.11    Undertaking for Costs.    


        In
any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as a Trustee, a court in its
discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable
attorneys' fees, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section 6.11 (to the extent
permitted by applicable law) does not apply to a suit by the Trustee, a suit by a Holder of a Note pursuant to Section 6.07 hereof, or a suit by Holders of more than 10% in principal amount of
the then outstanding Notes. 


ARTICLE 7.

TRUSTEE  


Section 7.01    Duties of Trustee.    



        (a)   If
an Event of Default has occurred and is continuing, the Trustee will exercise such of the rights and powers vested in it by this Indenture, and use the same degree of
care and skill in its 


56





 



exercise,
as a prudent person would exercise or use under the circumstances in the conduct of such person's own affairs. 


        (b)   Except
during the continuance of an Event of Default: 



        (1)   the
duties of the Trustee will be determined solely by the express provisions of this Indenture and the Trustee need perform only those duties that are specifically set
forth in this Indenture and no others, and no implied covenants or obligations shall be read into this Indenture against the Trustee; and 


        (2)   in
the absence of bad faith on its part, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon
certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture. However, the Trustee will examine the certificates and opinions to determine whether or not they
conform to the requirements of this Indenture. 




        (c)   The
Trustee may not be relieved from liabilities for its own negligent action, its own negligent failure to act, or its own willful misconduct, except that: 



        (1)   this
paragraph does not limit the effect of paragraph (b) of this Section 7.01; 



        (2)   the
Trustee will not be liable for any error of judgment made in good faith by a Responsible Officer, unless it is proved that the Trustee was negligent in ascertaining
the pertinent facts; and 


        (3)   the
Trustee will not be liable with respect to any action it takes or omits to take in good faith in accordance with a direction received by it pursuant to
Section 6.05 hereof. 




        (d)   Whether
or not therein expressly so provided, every provision of this Indenture that in any way relates to the Trustee is subject to paragraphs (a), (b), and
(c) of this Section 7.01. 


        (e)   No
provision of this Indenture will require the Trustee to expend or risk its own funds or incur any liability. The Trustee will be under no obligation to exercise any
of its rights and powers under this Indenture at the request of any Holders, unless such Holder has offered to the Trustee security and indemnity satisfactory to it against any loss, liability or
expense. 


        (f)    The
Trustee will not be liable for interest on any money received by it except as the Trustee may agree in writing with the Company. Money held in trust by the Trustee
need not be segregated from other funds except to the extent required by law. 



        (g)   Every
provision of this Indenture relating to the conduct or affecting the liability of or affording protections to the Trustee shall be subject to the provisions of
this Section 7.01 and the TIA. 


Section 7.02    Rights of Trustee.    


        (a)   The
Trustee may conclusively rely upon any document believed by it to be genuine and to have been signed or presented by the proper Person. The Trustee need not
investigate any fact or matter stated in the document. 


        (b)   Before
the Trustee acts or refrains from acting, it may require an Officers' Certificate or an Opinion of Counsel or both. The Trustee will not be liable for any action
it takes or omits to take in good faith in reliance on such Officers' Certificate or Opinion of Counsel. The Trustee may consult with counsel and the written advice of such counsel or any Opinion of
Counsel will be full and complete authorization and protection from liability in respect of any action taken, suffered or omitted by it hereunder in good faith and in reliance thereon. 



        (c)   The
Trustee may act through its attorneys and agents and will not be responsible for the misconduct or negligence of any agent appointed with due care. 


57





 



        (d)   The
Trustee will not be liable for any action it takes or omits to take in good faith that it believes to be authorized or within the rights or powers conferred upon it
by this Indenture. 


        (e)   Unless
otherwise specifically provided in this Indenture, any demand, request, direction or notice from MSW will be sufficient if signed by an Officer of MSW. 


        (f)    The
Trustee will be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request or direction of any of the Holders unless
such Holders have offered to the Trustee reasonable security or indemnity against the costs, expenses and liabilities that might be incurred by it in compliance with such request or direction. 


Section 7.03    Individual Rights of Trustee.    



        The
Trustee in its individual or any other capacity may become the owner or pledgee of Notes and may otherwise deal with MSW or any Affiliate of MSW with the same rights it would have if
it were not
Trustee. However, in the event that the Trustee acquires any conflicting interest it must eliminate such conflict within 90 days, apply to the SEC for permission to continue as trustee or
resign. Any Agent may do the same with like rights and duties. However, the Trustee must comply with Sections 7.10 and 7.11 hereof. 


Section 7.04    Trustee's Disclaimer.    



        The
Trustee will not be responsible for and makes no representation as to the validity or adequacy of this Indenture or the Notes, except as contained in the Trustee's certificate of
authentication. The Trustee shall not be accountable for the Company's use of the proceeds from the Notes or any money paid to the Company or upon the Company's direction under any provision of this
Indenture. The Trustee will not be responsible for the use or application of any money received by any Paying Agent other than the Trustee, and it will not be responsible for any statement or recital
herein or any statement in the Notes or any other document in connection with the sale of the Notes or pursuant to this Indenture other than its certificate of authentication. 



Section 7.05    Notice of Defaults.    


        If
a Default or Event of Default occurs and is continuing and if it is known to the Trustee, the Trustee will mail to Holders of Notes a notice of the Default or Event of Default within
90 days after it occurs. Except in the case of a Default or Event of Default in payment of principal of, premium or Additional Interest, if any, or interest on any Note, the Trustee may
withhold the notice if and so long as a committee of its Responsible Officers in good faith determines that withholding the notice is in the interests of the Holders of the Notes. 



Section 7.06    Reports by Trustee to Holders of the Notes.    


        (a)   Within
60 days after each June 25 beginning with the June 25 following the date of this Indenture, and for so long as Notes remain outstanding, the
Trustee will mail to the Holders of the Notes a brief report dated as of such reporting date that complies with TIA § 313(a) (but if no event described in TIA § 313(a) has
occurred within the twelve months preceding the reporting date, no report need be transmitted). The Trustee also will comply with TIA § 313(b)(2). The Trustee will also transmit by mail
all reports as required by TIA § 313(c). 


        (b)   A
copy of each report at the time of its mailing to the Holders of Notes will be mailed by the Trustee to the Company and filed by the Trustee with the SEC and each
stock exchange on which the Notes are listed in accordance with TIA § 313(d). The Company will promptly notify the Trustee when the Notes are listed on any stock exchange. 


Section 7.07    Compensation and Indemnity.    



        (a)   The
Company will pay to the Trustee from time to time reasonable compensation for its acceptance of this Indenture and services hereunder. The Trustee's compensation
will not be limited by 


58





 



any
law on compensation of a trustee of an express trust. The Company will reimburse the Trustee promptly upon request for all reasonable disbursements, advances and expenses incurred or made by it in
addition to the compensation for its services. Such expenses will include the reasonable compensation, disbursements and expenses of the Trustee's agents and counsel. 



        (b)   The
Company and the Guarantors will indemnify the Trustee against any and all losses, liabilities or expenses (including reasonable attorneys fees) incurred by it
arising out of or in connection with the acceptance or administration of its duties under this Indenture, including the costs and expenses of enforcing this Indenture against the Company and the
Guarantors (including this Section 7.07) and defending itself against any claim (whether asserted by the Company, the Guarantors or any Holder or any other Person) or liability in connection
with the exercise or performance of any of its powers or duties hereunder, except to the extent any such loss, liability or expense may be attributable to its negligence or bad faith. The Trustee will
notify the Company promptly of any claim for which it may seek indemnity. Failure by the Trustee to so notify the Company will not relieve the Company or any of the Guarantors of their obligations
hereunder. The Company or such Guarantor will defend the claim and the Trustee will cooperate in the defense. The Trustee may have separate counsel and the Company will pay the reasonable fees and
expenses of such counsel. Neither the Company nor any Guarantor need pay for any settlement made without its consent, which consent will not be unreasonably withheld. 


        (c)   The
obligations of the Company and the Guarantors under this Section 7.07 will survive the satisfaction and discharge of this Indenture. 



        (d)   To
secure the Company's payment obligations in this Section 7.07, the Trustee will have a Lien prior to the Notes on all money or property held or collected by
the Trustee in its capacity as Trustee under this Indenture, except that held in trust to pay principal and interest on particular Notes. Such Lien will survive the satisfaction and discharge of this
Indenture. 


        (e)   When
the Trustee incurs expenses or renders services after an Event of Default specified in Section 6.01(11) or (12) hereof occurs, the expenses and the
compensation for the services (including the fees and expenses of its agents and counsel) are intended to constitute expenses of administration under any Bankruptcy Law. 



        (f)    The
Trustee will comply with the provisions of TIA § 313(b)(2) to the extent applicable. 


Section 7.08    Replacement of Trustee.    


        (a)   A
resignation or removal of the Trustee and appointment of a successor Trustee will become effective only upon the successor Trustee's acceptance of appointment as
provided in this Section 7.08. 


        (b)   The
Trustee may resign in writing at any time and be discharged from the trust hereby created by so notifying the Company. The Holders of a majority in principal amount
of the then outstanding Notes may remove the Trustee by so notifying the Trustee and the Company in writing. The Company may remove the Trustee if: 



        (1)   the
Trustee fails to comply with Section 7.10 hereof; 


        (2)   the
Trustee is adjudged a bankrupt or an insolvent or an order for relief is entered with respect to the Trustee under any Bankruptcy Law; 



        (3)   a
custodian or public officer takes charge of the Trustee or its property; or 


        (4)   the
Trustee becomes incapable of acting. 




        (c)   If
the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for any reason, the Company will promptly appoint a successor Trustee. Within one
year after the successor Trustee takes office, the Holders of a majority in principal amount of the then outstanding Notes may appoint a successor Trustee to replace the successor Trustee appointed by
the Company. 


59





 

        (d)   If
a successor Trustee does not take office within 60 days after the retiring Trustee resigns or is removed, the retiring Trustee, the Company, or the Holders of
at least 10% in principal amount of the then outstanding Notes may petition any court of competent jurisdiction for the appointment of a successor Trustee. 


        (e)   If
the Trustee, after written request by any Holder who has been a Holder for at least six months, fails to comply with Section 7.10, such Holder may petition any
court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee. 


        (f)    A
successor Trustee will deliver a written acceptance of its appointment to the retiring Trustee and to the Company. Thereupon, the resignation or removal of the
retiring Trustee will become effective, and the successor Trustee will have all the rights, powers and duties of the Trustee under this Indenture. The successor Trustee will mail a notice of its
succession to Holders. The retiring Trustee will promptly transfer all property held by it as Trustee to the successor Trustee, provided all sums owing
to the Trustee hereunder have been paid and subject to the Lien provided for in Section 7.07 hereof. Notwithstanding replacement of the Trustee pursuant to this Section 7.08, the
Company's obligations under Section 7.07 hereof will continue for the benefit of the retiring Trustee. 


Section 7.09    Successor Trustee by Merger, etc.    


        If
the Trustee consolidates, merges or converts into, or transfers all or substantially all of its corporate trust business to, another corporation, the successor corporation without any
further act will be the successor Trustee. 


Section 7.10    Eligibility; Disqualification.    


        There
will at all times be a Trustee hereunder that is a corporation organized and doing business under the laws of the United States of America or of any state thereof that is
authorized under such laws to exercise corporate trustee power, that is subject to supervision or examination by federal or state authorities and that has a combined capital and surplus of at least
$100 million as set forth in its most recent published annual report of condition. 


        This
Indenture will always have a Trustee who satisfies the requirements of TIA § 310(a)(1), (2) and (5). The Trustee is subject to TIA §310(b). 


Section 7.11    Preferential Collection of Claims Against Company.    


        The
Trustee is subject to TIA § 311(a), excluding any creditor relationship listed in TIA § 311(b). A Trustee who has resigned or been removed shall be subject to
TIA § 311(a) to the extent indicated therein. 


ARTICLE 8.

LEGAL DEFEASANCE AND COVENANT DEFEASANCE  


Section 8.01    Option to Effect Legal Defeasance or Covenant Defeasance.    


        The
Company may, at the option of its Board of Directors evidenced by a resolution set forth in an Officers' Certificate, at any time, elect to have either Section 8.02 or 8.03
hereof be applied to all outstanding Notes upon compliance with the conditions set forth below in this Article 8. 


Section 8.02    Legal Defeasance and Discharge.    


        Upon
the Company's exercise under Section 8.01 hereof of the option applicable to this Section 8.02, the Company and each of the Guarantors will, subject to the
satisfaction of the conditions set forth in Section 8.04 hereof, be deemed to have been discharged from their obligations with respect to all outstanding Notes (including the Note
Guarantees)] on the date the conditions set forth below are satisfied (hereinafter, "Legal Defeasance"). For this purpose, Legal Defeasance
means that the 


60





 



Company
and the Guarantors will be deemed to have paid and discharged the entire Indebtedness represented by the outstanding Notes (including the Note Guarantees), which will thereafter be deemed to
be "outstanding" only for the purposes of Section 8.05 hereof and the other Sections of this Indenture referred to in clauses (1) and (2) below, and to have satisfied all their
other obligations under such Notes, the Note Guarantees and this Indenture (and the Trustee, on demand of and at the expense of the Company, shall execute proper instruments acknowledging the same),
except for the following provisions which will survive until otherwise terminated or discharged hereunder: 



        (1)   the
rights of Holders of outstanding Notes to receive payments in respect of the principal of, or interest or premium and Additional Interest, if any, on such Notes when
such payments are due from the trust referred to in Section 8.04 hereof; 


        (2)   the
Company's obligations with respect to such Notes under Article 2 and Section 4.02 hereof; 



        (3)   the
rights, powers, trusts, duties and immunities of the Trustee hereunder and the Company's and the Guarantors' obligations in connection therewith; and 


        (4)   this
Article 8. 




        Subject
to compliance with this Article 8, the Company may exercise its option under this Section 8.02 notwithstanding the prior exercise of its option under
Section 8.03 hereof. 


Section 8.03    Covenant Defeasance.    



        Upon
the Company's exercise under Section 8.01 hereof of the option applicable to this Section 8.03, the Company and the Guarantors shall, subject to the satisfaction of
the conditions set forth in Section 8.04 hereof, be released from each of their obligations under the covenants contained in Sections 4.03, 4.05, 4.07, 4.08, 4.09, 4.10, 4.11, 4.12, 4.13, 4.15,
4.17 4.18, 4.19 and 4.20 hereof and clause (4) of Section 5.01 hereof with respect to the outstanding Notes on and after the date the conditions set forth in Section 8.04 hereof
are satisfied (hereinafter, "Covenant Defeasance"), and the Notes will thereafter be deemed not "outstanding" for the purposes of any direction, waiver,
consent or declaration or act of Holders (and the consequences of any thereof) in connection with such covenants, but will continue to be deemed "outstanding" for all other purposes hereunder (it
being understood that such Notes will not be deemed outstanding for accounting purposes). For this purpose, Covenant Defeasance means that, with respect to the outstanding Notes and Note Guarantees,
the Company and the Guarantors may omit to comply with and shall have no liability in respect of any term, condition or limitation set forth in any such covenant, whether directly or indirectly, by
reason of any reference elsewhere herein to any such covenant or by reason of any reference in any such covenant to any other provision herein or in any other document and such omission to comply
shall not constitute a Default or an Event of Default under Section 6.01 hereof, but, except as specified above, the remainder of this Indenture and such Notes and Note Guarantees shall be
unaffected thereby. In addition, upon the Company's exercise under Section 8.01 hereof of the option applicable to this Section 8.03 hereof, subject to the satisfaction of the conditions
set forth in Section 8.04 hereof, Sections 6.01(3) through 6.01(7) and 6.01(9) hereof will not constitute Events of Default. 


61









   
Section 8.04    Conditions to Legal or Covenant Defeasance.    


        In
order to exercise either Legal Defeasance or Covenant Defeasance under either Section 8.02 or 8.03 hereof: 



        (1)   the
Company must irrevocably deposit with the Trustee, in trust, for the benefit of the Holders, cash in United States dollars, non-callable Government
Securities, or a combination thereof, in such amounts as will be sufficient, in the opinion of a nationally recognized firm of independent public accountants, to pay the principal of, premium and
Additional Interest, if any, and interest on the outstanding Notes on the stated date for payment thereof or on the applicable redemption date, as the case may be; 


        (2)   in
the case of an election under Section 8.02 hereof, the Company must deliver to the Trustee an Opinion of Counsel in the United States reasonably acceptable to
the Trustee confirming that: 



        (A)  the
Company has received from, or there has been published by, the Internal Revenue Service a ruling; or 


        (B)  since
the date of this Indenture, there has been a change in the applicable federal income tax law, 




in
either case to the effect that, and based thereon such Opinion of Counsel shall confirm that, the Holders of the outstanding Notes will not recognize income, gain or loss for federal income tax
purposes as a result of such Legal Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Legal
Defeasance had not occurred; 


        (3)   in
the case of an election under Section 8.03 hereof, the Company must deliver to the Trustee an Opinion of Counsel in the United States reasonably acceptable to
the Trustee confirming that the Holders of the outstanding Notes will not recognize income, gain or loss for federal income tax purposes as a result of such Covenant Defeasance and will be subject to
federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Covenant Defeasance had not occurred; 


        (4)   no
Default or Event of Default shall have occurred and be continuing on the date of such deposit (other than a Default or Event of Default resulting from the borrowing
of funds to be applied to such deposit); 


        (5)   such
Legal Defeasance or Covenant Defeasance will not result in a breach or violation of, or constitute a default under, any material agreement or instrument (other than
this Indenture) to which MSW or any of its Subsidiaries is a party or by which MSW or any of its Subsidiaries is bound; 


        (6)   the
Company must deliver to the Trustee an Officers' Certificate stating that the deposit was not made by the Company with the intent of preferring the Holders of Notes
over the other creditors of the Company with the intent of defeating, hindering, delaying or defrauding any other creditors of the Company or others; and 



        (7)   the
Company must deliver to the Trustee an Officers' Certificate and an Opinion of Counsel, each stating that all conditions precedent relating to the Legal Defeasance
or the Covenant Defeasance have been complied with. 




Section 8.05    Deposited Money and Government Securities to be Held in Trust; Other Miscellaneous Provisions.    


62





 

        Subject
to Section 8.06 hereof, all money and non-callable Government Securities (including the proceeds thereof) deposited with the Trustee (or other qualifying
trustee, collectively for purposes of this Section 8.05, the "Trustee") pursuant to Section 8.04 hereof in respect of the outstanding Notes will be held in trust and applied by the
Trustee, in accordance with the provisions of such Notes and this Indenture, to the payment, either directly or through any Paying Agent (including the Company acting as Paying Agent) as the Trustee
may determine, to the Holders of such Notes of all sums due and to become due thereon in respect of principal, premium and Additional Interest, if any, and interest, but such money need not be
segregated from other funds except to the extent required by law. 


        The
Company will pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the cash or non-callable Government Securities deposited
pursuant to Section 8.04 hereof or the principal and interest received in respect thereof other than any such tax, fee or other charge which by law is for the account of the Holders of the
outstanding Notes. 


        Notwithstanding
anything in this Article 8 to the contrary, the Trustee will deliver or pay to the Company from time to time upon the request of the Company any money or
non-callable Government Securities held by it as provided in Section 8.04 hereof which, in the opinion of a nationally recognized firm of independent public accountants expressed in
a written certification thereof delivered to the Trustee (which may be the opinion delivered under Section 8.04(1) hereof), are in excess of the amount thereof that would then be required to be
deposited to effect an equivalent Legal Defeasance or Covenant Defeasance. 


Section 8.06    Repayment to Company.    


        Any
money deposited with the Trustee or any Paying Agent, or then held by the Company, in trust for the payment of the principal of, premium or Additional Interest, if any, or interest
on any Note and remaining unclaimed for two years after such principal, premium or Additional Interest, if any, or interest has become due and payable shall be paid to the Company on its request or
(if then held by the Company) will be discharged from such trust; and the Holder of such Note will thereafter be permitted to look only to the Company for payment thereof, and all liability of the
Trustee or such Paying Agent with respect to such trust money, and all liability of the Company as trustee thereof, will thereupon cease; provided,
however, that the Trustee or such Paying Agent, before being required to make any such repayment, may at the expense of the Company cause to be published once, in the New York
Times and The Wall Street Journal (national edition), notice that such money remains unclaimed and that, after a date specified therein, which will not be less than 30 days from the date of
such notification or publication, any unclaimed balance of such money then remaining will be repaid to the Company. 


Section 8.07    Reinstatement.    


        If
the Trustee or Paying Agent is unable to apply any United States dollars or non-callable Government Securities in accordance with Section 8.02 or 8.03 hereof, as
the case may be, by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the Company's and the Guarantor's
obligations under this Indenture and the Notes and the Note Guarantees will be revived and reinstated as though no deposit had occurred pursuant to Section 8.02 or 8.03 hereof until such time
as the Trustee or Paying Agent is permitted to apply all such money in accordance with Section 8.02 or 8.03 hereof, as the case may be; provided,
however, that, if the Company makes any payment of principal of, premium or Additional Interest, if any, or interest on any Note following the reinstatement of its obligations,
the Company will be subrogated to the rights of the Holders of such Notes to receive such payment from the money held by the Trustee or Paying Agent.

ARTICLE 9.

AMENDMENT, SUPPLEMENT AND WAIVER  


Section 9.01    Without Consent of Holders of Notes.    


        Notwithstanding
Section 9.02 of this Indenture, the Company, the Guarantors and the Trustee may amend or supplement this Indenture, the Note Guarantees or the Notes without the
consent of any Holder of a Note: 



        (1)   to
cure any ambiguity, defect or inconsistency; 


        (2)   to
provide for uncertificated Notes in addition to or in place of certificated Notes or to alter the provisions of Article 2 hereof (including the related
definitions) in a manner that does not materially adversely affect any Holder; 


        (3)   to
provide for the assumption of the Company's or a Guarantor's obligations to the Holders of the Notes by a successor to the Company pursuant to Article 5
hereof; 


        (4)   to
make any change that would provide any additional rights or benefits to the Holders of the Notes or that does not adversely affect the legal rights hereunder of any
Holder; 


        (5)   to
comply with requirements of the SEC in order to effect or maintain the qualification of this Indenture under the TIA; 


        (6)   to
provide for the issuance of Additional Notes in accordance with the limitations set forth in this Indenture as of the date hereof; 


        (7)   to
allow any Guarantor to execute a supplemental indenture and/or a Note Guarantee with respect to the Notes; 


        (8)   to
implement the arrangements contemplated by Section 4.19 hereof; and 


        (9)   to
conform the text of this Indenture, the Note Guarantees, the Pledge Agreement, the Deposit Agreement or the Notes to any provision of the section entitled
"Description of Notes" in the Offering Memorandum to the extent that such provision in such section was intended to be a verbatim recitation of a provision of this Indenture, the Note Guarantees, the
Pledge Agreement, the Deposit Agreement or the Notes. 




        Upon
the request of the Company accompanied by a resolution of its Board of Directors authorizing the execution of any such amended or supplemental Indenture, and upon receipt by the
Trustee of the documents described in Section 7.02 hereof, the Trustee will join with the Company and the Guarantors in the execution of any amended or supplemental Indenture authorized or
permitted by the terms of this Indenture and to make any further appropriate agreements and stipulations that may be therein contained, but the Trustee will not be obligated to enter into such amended
or supplemental Indenture that affects its own rights, duties or immunities under this Indenture or otherwise. 


Section 9.02    With Consent of Holders of Notes.    


        Except
as provided below in this Section 9.02, the Company and the Trustee may amend or supplement this Indenture (including, without limitation, Section 3.09, 4.10 and
4.15 hereof), the Note Guarantees, the Notes, the Pledge Agreement or the Deposit Agreement with the consent of the Holders of at least a majority in principal amount of the Notes (including, without
limitation, Additional Notes, if any) then outstanding voting as a single class (including, without limitation, consents obtained in connection with a tender offer or exchange offer for, or purchase
of, the Notes), and, subject to Sections 6.04 and 6.07 hereof, any existing Default or Event of Default or compliance with any provision of this Indenture, the Note Guarantees, the Notes, the Pledge

in connection with a 


64





 



tender
offer or exchange offer for, or purchase of, the Notes). Section 2.08 hereof shall determine which Notes are considered to be "outstanding" for purposes of this Section 9.02. 



        Upon
the request of the Company accompanied by a resolution of its Board of Directors authorizing the execution of any such amended or supplemental Indenture, and upon the filing with
the Trustee of evidence satisfactory to the Trustee of the consent of the Holders of Notes as aforesaid, and upon receipt by the Trustee of the documents described in Section 7.02 hereof, the
Trustee will join with the Company and the Guarantors in the execution of such amended or supplemental Indenture unless such amended or supplemental Indenture directly affects the Trustee's own
rights, duties or immunities under this Indenture or otherwise, in which case the Trustee may in its discretion, but will not be obligated to, enter into such amended or supplemental Indenture. 



        It
is not necessary for the consent of the Holders of Notes under this Section 9.02 to approve the particular form of any proposed amendment or waiver, but it is sufficient if
such consent approves the substance thereof. 


        After
an amendment, supplement or waiver under this Section 9.02 becomes effective, the Company will mail to the Holders of Notes affected thereby a notice briefly describing the
amendment, supplement or waiver. Any failure of the Company to mail such notice, or any defect therein, will not, however, in any way impair or affect the validity of any such amended or supplemental
Indenture or waiver. Subject to Sections 6.04 and 6.07 hereof, the Holders of a majority in aggregate principal amount of the Notes then outstanding voting as a single class may waive compliance in a
particular instance by the Company with any provision of this Indenture or the Notes. 


        Notwithstanding
anything to the contrary contained in this Section 9.02, without the consent of each Holder affected, an amendment or waiver under this Section 9.02 may not
(with respect to any Notes held by a non-consenting Holder): 



        (1)   reduce
the principal amount of Notes whose Holders must consent to an amendment, supplement or waiver; 



        (2)   reduce
the principal of or change the fixed maturity of any Note or alter or waive any of the provisions with respect to the redemption of the Notes except as provided
above with respect to Sections 3.09, 4.10 and 4.15 hereof; 


        (3)   reduce
the rate of or change the time for payment of interest, including default interest, on any Note; 


        (4)   waive
a Default or Event of Default in the payment of principal of or premium or Additional Interest, if any, or interest on the Notes (except a rescission of
acceleration of the Notes by the Holders of at least a majority in aggregate principal amount of the then outstanding Notes and a waiver of the payment default that resulted from such acceleration); 


        (5)   make
any Note payable in money other than that stated in the Notes; 


        (6)   make
any change in the provisions of this Indenture relating to waivers of past Defaults or the rights of Holders of Notes to receive payments of principal of, or
interest or premium or Additional Interest, if any, on the Notes; 


        (7)   waive
a redemption payment with respect to any Note (except a payment pursuant to Sections 3.09, 4.10 or 4.15 hereof); 



        (8)   release
any Guarantor from any of its obligations under its Note Guarantee or this Indenture, except in accordance with the terms of this Indenture; or 


        (9)   make
any change in this Section 9.02.

Section 9.03    Compliance with Trust Indenture Act.    



        Every
amendment or supplement to this Indenture or the Notes will be set forth in an amended or supplemental Indenture that complies with the TIA as then in effect. 


Section 9.04    Revocation and Effect of Consents.    


        Until
an amendment, supplement or waiver becomes effective, a consent to it by a Holder of a Note is a continuing consent by the Holder of a Note and every subsequent Holder of a Note or
portion of a Note that evidences the same debt as the consenting Holder's Note, even if notation of the consent is not made on any Note. However, any such Holder of a Note or subsequent Holder of a
Note may revoke the consent as to its Note if the Trustee receives written notice of revocation before the date the waiver, supplement or amendment becomes effective. An amendment, supplement or
waiver becomes effective in accordance with its terms and thereafter binds every Holder. 


Section 9.05    Notation on or Exchange of Notes.    


        The
Trustee may place an appropriate notation about an amendment, supplement or waiver on any Note thereafter authenticated. The Company in exchange for all Notes may issue and the
Trustee shall, upon receipt of an Authentication Order, authenticate new Notes that reflect the amendment, supplement or waiver. 



        Failure
to make the appropriate notation or issue a new Note will not affect the validity and effect of such amendment, supplement or waiver. 


Section 9.06    Trustee to Sign Amendments, etc.    


        The
Trustee will sign any amended or supplemental Indenture authorized pursuant to this Article 9 if the amendment or supplement does not adversely affect the rights, duties,
liabilities or immunities of the Trustee. The Company may not sign an amendment or supplemental Indenture until the Board of Directors approves it. In executing any amended or supplemental indenture,
the Trustee will be entitled to receive and (subject to Section 7.01 hereof) will be fully protected in relying upon, in addition to the documents required by Section 12.04 hereof, an
Officers' Certificate and an Opinion of Counsel stating that the execution of such amended or supplemental Indenture is authorized or permitted by this Indenture. 


ARTICLE 10.

COLLATERAL AND SECURITY  


Section 10.01    Pledge Agreement and Deposit Agreement.

the
Trustee copies of all documents delivered to the Collateral Agent pursuant to the Pledge Agreement and the Deposit Agreement, and will 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 Pledge Agreement and the Deposit Agreement, to assure and confirm to the Trustee and the Collateral Agent the security interest in
the Collateral contemplated hereby, by the Pledge Agreement, and the Pledged Accounts and Pledged Account Funds, by the Deposit Agreement, or any part thereof, as from time to time constituted, so as
to render the same available for the security and benefit of this Indenture and of the Notes secured hereby, according to the intent and purposes herein expressed. MSW shall take, and shall cause its
Subsidiaries to take, upon request of the Trustee, any and all actions reasonably required to cause the Pledge Agreement and the Deposit Agreement to create and maintain, as security for the
Obligations of the Company hereunder, a valid and enforceable perfected first priority Lien in and on all the Collateral, the Pledged Accounts and the Pledged Account Funds, in favor of the Collateral
Agent for the benefit of the Holders of Notes and holders of Parity Lien Obligations, superior to and prior to the rights of all third Persons and subject to no other Liens other than Permitted Liens. 


Section 10.02    Recording and Opinions.    



        (a)   The
Company will furnish to the Trustee promptly after the execution and delivery of this Indenture an Opinion of Counsel either: 



        (1)   stating
that, in the opinion of such counsel, all action has been taken with respect to the recording, registering and filing of this Indenture, financing statements or
other instruments necessary to make effective the Lien intended to be created by the Pledge Agreement, and reciting with respect to the security interests in the Pledged Collateral, the details of
such action; or 


        (2)   stating
that, in the opinion of such counsel, no such action is necessary to make such Lien effective. 




        (b)   The
Company will furnish to the Collateral Agent and the Trustee on July 1 in each year beginning with July 1, 2004, an Opinion of Counsel, dated as of
such date, either:

the Lien of the Pledge Agreement and reciting with respect to the security interests in the Collateral the details of such action or referring to prior Opinions of Counsel in which such details are
given, and (B) stating that, in the opinion of such counsel, based on relevant laws as in effect on the date of such Opinion of Counsel, all financing statements and continuation statements
have been executed and filed that are necessary as of such date and during the succeeding 12 months fully to preserve and protect, to the extent such protection and preservation are possible by
filing, the rights of the Holders of Notes and the Collateral Agent and the Trustee hereunder and under the Pledge Agreement with respect to the security interests in the Collateral; 



        (2)   stating
that, in the opinion of such counsel, no such action is necessary to maintain such Lien and assignment. 




        (c)   The

that if such sale, conveyance or disposition constitutes an ARC Asset Sale, the Company will apply the Excess Proceeds in accordance with Section 4.10 hereof. Upon receipt of such Officers'
Certificate the Collateral Agent 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 Indenture or the Pledge Agreement. Any transfer of funds in accordance with the terms and conditions set forth in the Deposit Agreement will not be considered a release
of Collateral for purposes of this Article 10. 


        (b)   No
Collateral may be released from the Lien and security interest created by the Pledge Agreement pursuant to the provisions of the Pledge Agreement unless the
certificate required by this Section 10.03 has been delivered to the Collateral Agent, except for transfers of cash pursuant to Section 4(b)(iii)(C)(3) of the Pledge Agreement. 



        (c)   At
any time when a Default or Event of Default has occurred and is continuing and the maturity of the Notes has been accelerated (whether by declaration or otherwise)
and the Trustee has delivered a notice of acceleration to the Collateral Agent, no release of Collateral pursuant to the provisions of the Pledge Agreement will be effective as against the Holders of
Notes. 


        (d)   The
release of any Collateral from the terms of this Indenture and the Pledge Agreement will not be deemed to impair the security under this Indenture in contravention
of the provisions hereof if and to the extent the Collateral is released pursuant to the terms of the Pledge Agreement. To the extent applicable, the Company will cause TIA § 313(b),
relating to reports, and TIA § 314(d), relating to the release of property or securities from the Lien and security interest of the Pledge Agreement and relating to the substitution
therefor of any property or securities to be subjected to the Lien and security interest of the Pledge Agreement and the Deposit Agreement, to be complied with. Any certificate or opinion required by
TIA § 314(d) may be made by an Officer of the Company except in cases where TIA § 314(d) requires that such certificate or opinion be made by an independent Person, which
Person will be an independent engineer, appraiser or other expert selected or approved by the Trustee and the Collateral Agent in the exercise of reasonable care. 


Section 10.04    Certificates of the Company.    


        The
Company will furnish to the Trustee and the Collateral Agent, prior to each proposed release of Collateral pursuant to the Pledge Agreement: 



        (1)   all
documents required by TIA §314(d); and 


        (2)   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
§314(d). 




        The
Trustee may, to the extent permitted by Sections 7.01 and 7.02 hereof, accept as conclusive evidence of compliance with the foregoing provisions the appropriate statements contained
in such documents and such Opinion of Counsel. 


Section 10.05    Certificates of the Trustee.    


        In
the event that the Company wishes to release Collateral in accordance with the Pledge Agreement and has delivered the certificates and documents required by the Pledge Agreement and
Sections 10.03 and 10.04 hereof, the Trustee will determine whether it has received all documentation required by TIA §314(d) in connection with such release and, based on such
determination and the Opinion of Counsel delivered pursuant to Section 10.04(2), will deliver a certificate to the Collateral Agent setting forth such determination.

Section 10.06    Authorization of Actions to Be Taken by the Trustee.    


        Subject
to the provisions of Section 7.01 and 7.02 hereof, the Trustee may, in its sole discretion and without the consent of the Holders of Notes, direct, on behalf of the
Holders of Notes, the Collateral Agent to, take all actions it deems necessary or appropriate in order to: 



        (1)   enforce
any of the terms of the Pledge Agreement or the Deposit Agreement; and 


        (2)   collect
and receive any and all amounts payable in respect of the Obligations of the Company hereunder. 




        The
Trustee will have power to institute and maintain such suits and proceedings as it may deem expedient to prevent any impairment of the Collateral by any acts that may be unlawful or
in violation of the Pledge Agreement, the Deposit Agreement or this Indenture, and such suits and proceedings as the Trustee may deem expedient to preserve or protect its interests and the interests
of the Holders of Notes in the Collateral (including power to institute and maintain suits or proceedings to restrain the enforcement of or compliance with any legislative or other governmental
enactment, rule or order that may be unconstitutional or otherwise invalid if the enforcement of, or compliance with, such enactment, rule or order would impair the security interest hereunder or be
prejudicial to the interests of the Holders of Notes or of the Trustee). 


Section 10.07    Authorization of Receipt of Funds by the Trustee.    


        The
Trustee is authorized to receive any funds for the benefit of the Holders of Notes distributed under the Pledge Agreement and the Deposit Agreement, and to make further distributions
of such funds to the Holders of Notes according to the provisions of this Indenture. 


Section 10.08    Termination of Security Interest.    



        Upon
the payment in full of all Obligations of the Company under this Indenture and the Notes, or upon Legal Defeasance, the Trustee will, at the request of the Company, deliver a
certificate to the Collateral Agent stating that such Obligations have been paid in full, and instruct the Collateral Agent to release the Liens pursuant to this Indenture and the Pledge Agreement. 


ARTICLE 11.

NOTE GUARANTEES  


Section 11.01    Guarantee.    



        (a)   Subject
to this Article 11, each of the Guarantors hereby, jointly and severally, unconditionally guarantees to each Holder of a Note authenticated and delivered
by the Trustee and to the Trustee and its successors and assigns, irrespective of the validity and enforceability of this Indenture, the Notes or the obligations of the Company hereunder or
thereunder, that: 



        (1)   the
principal of, premium and Additional Interest, if any, and interest on the Notes will be promptly paid in full when due, whether at maturity, by acceleration,
redemption or otherwise, and interest on the overdue principal of and interest on the Notes, if any, if lawful, and all other obligations of the Company to the Holders or the Trustee hereunder or
thereunder will be promptly paid in full or performed, all in accordance with the terms hereof and thereof; and 


        (2)   in
case of any extension of time of payment or renewal of any Notes or any of such other obligations, that same will be promptly paid in full when due or performed in
accordance with the terms of the extension or renewal, whether at stated maturity, by acceleration or otherwise. 




        Failing
payment when due of any amount so guaranteed or any performance so guaranteed for whatever reason, the Guarantors will be jointly and severally obligated to pay the same
immediately. Each Guarantor agrees that this is a guarantee of payment and not a guarantee of collection. 


69





 

        (b)   The
Guarantors hereby agree that their obligations hereunder are unconditional, irrespective of the validity, regularity or enforceability of the Notes or this
Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder of the Notes with respect to any provisions hereof or thereof, the recovery of any judgment against the
Company, any action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a guarantor. Each Guarantor hereby waives diligence,
presentment, demand of payment, filing of claims with a court in the event of insolvency or bankruptcy of the Company, any right to require a proceeding first against the Company, protest, notice and
all demands whatsoever and covenant that this Note Guarantee will not be discharged except by complete performance of the obligations contained in the Notes and this Indenture. 


        (c)   If
any Holder or the Trustee is required by any court or otherwise to return to the Company, the Guarantors or any custodian, trustee, liquidator or other similar
official acting in relation to either the Company or the Guarantors, any amount paid by either to the Trustee or such Holder, this Note Guarantee, to the extent theretofore discharged, will be
reinstated in full force and effect. 


        (d)   Each
Guarantor agrees that it will not be entitled to any right of subrogation in relation to the Holders in respect of any obligations guaranteed hereby until payment
in full of all obligations guaranteed hereby. Each Guarantor further agrees that, as between the Guarantors, on the one hand, and the Holders and the Trustee, on the other hand, (1) the
maturity of the obligations guaranteed hereby may be accelerated as provided in Article 6 hereof for the purposes of this Note Guarantee, notwithstanding any stay, injunction or other
prohibition preventing such acceleration in respect of the obligations guaranteed hereby, and (2) in the event of any declaration of acceleration of such obligations as provided in
Article 6 hereof, such obligations (whether or not due and payable) will forthwith become due and payable by the Guarantors for the purpose of this Note Guarantee. The Guarantors will have the
right to seek contribution from any non-paying Guarantor so long as the exercise of such right does not impair the rights of the Holders under the Note Guarantee. 


Section 11.02    Limitation on Guarantor Liability.    


        Each
Guarantor, and by its acceptance of Notes, each Holder, hereby confirms that it is the intention of all such parties that the Note Guarantee of such Guarantor not constitute a
fraudulent transfer or conveyance for purposes of Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar federal or state law to the extent
applicable to any Note Guarantee. To effectuate the foregoing intention, the Trustee, the Holders and the Guarantors hereby
irrevocably agree that the obligations of such Guarantor will be limited to the maximum amount that will, after giving effect to such maximum amount and all other contingent and fixed liabilities of
such Guarantor that are relevant under such laws, and after giving effect to any collections from, rights to receive contribution from or payments made by or on behalf of any other Guarantor in
respect of the obligations of such other Guarantor under this Article 11, result in the obligations of such Guarantor under its Note Guarantee not constituting a fraudulent transfer or
conveyance. 


Section 11.03    Execution and Delivery of Note Guarantee.    


        To
evidence its Note Guarantee set forth in Section 11.01, each Guarantor hereby agrees that a notation of such Note Guarantee substantially in the form attached as
Exhibit E hereto will be endorsed by an Officer of such Guarantor on each Note authenticated and delivered by the Trustee and that a supplemental indenture will be executed on behalf of such
Guarantor by one of its Officers. 



        Each
Guarantor hereby agrees that its Note Guarantee set forth in Section 11.01 will remain in full force and effect notwithstanding any failure to endorse on each Note a
notation of such Note Guarantee. 


70





 



        If
an Officer whose signature is on this Indenture or on the Note Guarantee no longer holds that office at the time the Trustee authenticates the Note on which a Note Guarantee is
endorsed, the Note Guarantee will be valid nevertheless. 


        The
delivery of any Note by the Trustee, after the authentication thereof hereunder, will constitute due delivery of the Note Guarantee set forth in this Indenture on behalf of the
Guarantors. 


        In
the event that MSW or any of its Restricted Subsidiaries creates, acquires or obtains control of any Subsidiary after the date of this Indenture, if required by Section 4.17
hereof, MSW or such Restricted Subsidiary shall cause such Subsidiary to comply with the provisions of Section 4.17 hereof and this Article 11, to the extent applicable. 



Section 11.04    Guarantors May Consolidate, etc., on Certain Terms.    


        Except
as otherwise provided in Section 11.05, no Guarantor may sell or otherwise dispose of all or substantially all of its assets to, or consolidate with or merge with or into
(whether or not such Guarantor is the surviving Person) another Person, other than MSW or another Guarantor, unless: 



        (1)   immediately
after giving effect to such transaction, no Default or Event of Default exists; and 



        (2)   the
Person acquiring the property in any such sale or disposition or the Person formed by or surviving any such consolidation or merger unconditionally assumes all the
obligations of that Guarantor, pursuant to a supplemental indenture in form and substance reasonably satisfactory to the Trustee, under the Notes, this Indenture, the Note Guarantee and the Pledge
Agreement on the terms set forth herein or therein. 




        In
case of any such consolidation, merger, sale or conveyance and upon the assumption by the successor Person, by supplemental indenture, executed and delivered to the Trustee and
satisfactory in form to the Trustee, of the Note Guarantee endorsed upon the Notes and the due and punctual performance of all of the covenants and conditions of this Indenture to be performed by the
Guarantor, such successor Person will succeed to and be substituted for the Guarantor with the same effect as if it had been named herein as a Guarantor. Such successor Person thereupon may cause to
be signed any or all of the Note Guarantees to be endorsed upon all of the Notes issuable hereunder which theretofore shall not have been signed by the Company and delivered to the Trustee. All the
Note Guarantees so issued will in all respects have the same legal rank and benefit under this Indenture as the Note Guarantees theretofore and thereafter issued in accordance with the terms of this
Indenture as though all of such Note Guarantees had been issued at the date of the execution hereof. 


        Except
as set forth in Articles 4 and 5 hereof, and notwithstanding clauses (a) and (b) above, nothing contained in this Indenture or in any of the Notes will prevent any
consolidation or merger of a Guarantor with or into MSW or another Guarantor, or will prevent any sale or conveyance of the property of a Guarantor as an entirety or substantially as an entirety to
MSW or another Guarantor. 


Section 11.05    Releases.    


        In
the event of any sale or other disposition of all or substantially all of the assets of any Guarantor, by way of merger, consolidation or otherwise, or a sale or other disposition of
all of the Capital Stock of any Guarantor, in each case to a Person that is not (either before or after giving effect to such transactions) a Restricted Subsidiary of MSW, then such Guarantor (in the
event of a sale or other disposition, by way of merger, consolidation or otherwise, of all of the capital stock of such Guarantor) or the corporation acquiring the property (in the event of a sale or
other disposition of all or substantially all of the assets of such Guarantor) will be released and relieved of any obligations under its Note Guarantee. Upon delivery by the Company to the Trustee of
an Officers' Certificate and an Opinion of Counsel to the effect that such sale or other disposition was made by the Company in 


71





 



accordance
with the provisions of this Indenture, the Trustee will execute any documents reasonably required in order to evidence the release of any Guarantor from its obligations under its Note
Guarantee. The Note Guarantee of a Guarantor shall be released upon its designation by MSW as an Unrestricted Subsidiary in accordance with the terms of this Indenture. 


        Any
Guarantor not released from its obligations under its Note Guarantee will remain liable for the full amount of principal of and interest on the Notes and for the other obligations of
any Guarantor under this Indenture as provided in this Article 11. 


ARTICLE 12.

COLLATERAL SHARING WITH PARITY LIENS  


Section 12.01    Prerequisites to incurring Parity Lien Debt.    



        (a)   Prior
to incurring any Parity Lien Debt, the Company will deliver to the Trustee and the Collateral Agent an Officer's Certificate stating that: 



        (1)   the
Company intends to incur, on a date stated therein, Indebtedness that will constitute Parity Lien Debt; 


        (2)   no
Default or Event of Default exists on the date of such Officer's Certificate or will exist after giving effect to the incurrence of such Indebtedness; 



        (3)   the
Company has appointed the Collateral Agent to hold the security interest on behalf of such Parity Lien Debt in accordance with the Pledge Agreement and has taken all
steps necessary to make the Pledge Agreement and the Deposit Agreement applicable to the Parity Lien Debt; 


        (4)   the
Company will take all actions as may be necessary to grant or confirm the grant of Collateral to the Collateral Agent as security for all present and future Note
Obligations and Parity Lien Obligations, and shall take such action to perfect such security interest such that after giving effect thereto the Collateral Agent will hold as security for all present
and future Note Obligations and Parity Lien Obligations, a valid and perfected security interest upon all or substantially all of the Collateral that, immediately prior to giving effect thereto, was
subject to the Liens on the Notes; 


        (5)   the
Liens securing such proposed Parity Lien Debt will not be subject or subordinate to any Lien securing Indebtedness other than Liens permitted by clause (6) of
the definition of "Permitted Liens" and any other Permitted Lien to which the Notes are subject or subordinate to; and 


        (6)   the
Company and its Subsidiaries will, on such date, enter into all amendments, if any, to the Pledge Agreement and the Deposit Agreement then in effect that are
necessary to add Parity Lien Obligations to the obligations secured thereby, pursuant to amendments delivered to the Collateral Agent therewith, to be executed on such date by the Collateral Agent and
the Company or the Subsidiary party to the Pledge Agreement; 




        (b)   the
holders of any Parity Lien Obligations, or a representative on their behalf, shall execute and deliver a contractual undertaking in substantially the form of the
Joinder Agreement attached as Exhibit B to the Pledge Agreement whereby such persons agree to be bound by the lien sharing provisions of this Indenture; 



        (c)   the
Company will deliver to the Trustee and the Collateral Agent, as the case may be, opinions of counsel confirming on customary terms: 



        (1)   the
validity and enforceability of each of the Pledge Agreement and the Deposit Agreement, as amended, delivered to the Collateral Agent; 



72





 

        (2)   the
validity, enforceability and perfection of the Liens granted by such Pledge Agreement, as amended; 


        (3)   that
the Note Obligations and Parity Lien Obligations (i) are secured by equal and ratable security interests in the Collateral and (ii) that the holders
of any such Parity Lien Obligations or their representative have duly executed and delivered a contractual undertaking in substantially the form of the Joinder Agreement attached as Exhibit B
to the Pledge Agreement whereby such persons agree to be bound by the lien sharing provisions of this Indenture and that such contractual undertaking is legally binding and enforceable on such holders
of Parity Lien Debt; and 


        (4)   the
continued perfection of the Note Liens, without loss of priority as against any Lien other than Parity Liens, upon giving effect to the inclusion of such Parity Lien
Obligation in any such amendment of the Pledge Agreement, 




then,
subject to the terms of the Pledge Agreement and the Deposit Agreement, the Trustee will direct the Collateral Agent to execute and deliver such amendments to the Pledge Agreement and the
Deposit Agreement, if any, as may be necessary to accomplish the foregoing and the Collateral Agent will countersign the Joinder Agreement thereby confirming that it will hold the Note Liens and the
Pledge Agreement and the Liens granted thereby for the benefit of the holders of the Note Obligations and Parity Lien Obligations on the terms of such Pledge Agreement. 


Section 12.02    Equal and Ratable Lien Sharing.

filed or recorded to perfect any Lien upon any Collateral, (iv) the time of taking possession or control over any Collateral or (v) the rules for determining priority under the Uniform
Commercial Code or any other law governing relative priorities of secured creditors: 


        (a)   the
Note Liens will rank equally and ratably with all valid, enforceable and perfected Parity Liens, whenever granted upon any present or future Collateral, but only to
the extent such Parity Liens secure Parity Lien Obligations, and 


        (b)   all
proceeds of the Note Liens and Parity Liens shall be allocated and distributed equally and ratably on account of the Note Obligations and Parity Lien Obligations. 


Section 12.03    Enforcement.    


        The
provisions of Section 12.01(b) are intended for the benefit solely of the Company and shall be enforceable by the Company against the Trustee, the Collateral Agent and the
Holders of Notes. The provisions of Section 12.02 are binding upon and intended for the benefit of the Collateral Agent and each present and future holder of Note Obligations and Parity Lien
Obligations, each of whom shall be entitled to enforce such provisions as a third party beneficiary hereof. 


Section 12.04    Amendment.    


        (a)   No
amendment or supplement to the provisions of this Article 12 will: 



        (1)   be

ARTICLE 13.

SATISFACTION AND DISCHARGE  


Section 13.01    Satisfaction and Discharge.    


        This
Indenture will be discharged and will cease to be of further effect as to all Notes issued hereunder, when: 



        (1)   either:




        (a)   all
Notes that have been authenticated (except lost, stolen or destroyed Notes that have been replaced or paid and Notes for whose payment money has theretofore been
deposited in trust and thereafter repaid to the Company) have been delivered to the Trustee for cancellation; or 


        (b)   all
Notes that have not been delivered to the Trustee for cancellation have become due and payable by reason of the mailing of a notice of redemption or otherwise or
will become due and payable within one year and the Company or any Guarantor has irrevocably deposited or caused to be deposited with the Trustee as trust funds in trust solely for the benefit of the
Holders, cash in U.S. dollars, non-callable Government Securities, or a combination thereof, in such amounts as will be sufficient without consideration of any reinvestment of interest, to
pay and discharge the entire Indebtedness on the Notes not delivered to the Trustee for cancellation for principal, premium and Additional Interest, if any, and accrued interest to the date of
maturity or redemption; 




        (2)   with
respect to Section 13.01(1)(b), no Default or Event of Default has occurred and is continuing on the date of such deposit or will occur as a result of such
deposit and such deposit will not result in a breach or violation of, or constitute a default under, any other instrument to which the Company or any Guarantor is a party or by which the Company or
any Guarantor is bound; 


        (3)   the
Company or any Guarantor has paid or caused to be paid all sums payable by it under this Indenture; and 



        (4)   with
respect to Section 13.01(1)(b), the Company has delivered irrevocable instructions to the Trustee under this Indenture to apply the deposited money toward
the payment of the Notes at maturity or the redemption date, as the case may be. 




In
addition, the Company must deliver an Officers' Certificate and an Opinion of Counsel to the Trustee stating that all conditions precedent to satisfaction and discharge have been satisfied. 


        Notwithstanding
the satisfaction and discharge of this Indenture, if money has been deposited with the Trustee pursuant to subclause (b) of clause (1) of this Section, the
provisions of Section 13.02 and Section 8.06 will survive. In addition, nothing in this Section 13.01 will be deemed to discharge those 


74





 



provisions
of Section 7.07 hereof, that, by their terms, survive the satisfaction and discharge of this Indenture. 


Section 13.02    Application of Trust Money.    



        Subject
to the provisions of Section 8.06, all money deposited with the Trustee pursuant to Section 13.01 shall be held in trust and applied by it, in accordance with the
provisions of the Notes and this Indenture, to the payment, either directly or through any Paying Agent (including the Company acting as its own Paying Agent) as the Trustee may determine, to the
Persons entitled thereto, of the principal (and premium, if any) and interest for whose payment such money has been deposited with the Trustee; but such money need not be segregated from other funds
except to the extent required by law. 


        If
the Trustee or Paying Agent is unable to apply any money or Government Securities in accordance with Section 13.01 by reason of any legal proceeding or by reason of any order
or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the Company's and any Guarantor's obligations under this Indenture and the Notes
shall be revived and reinstated as though no deposit had occurred pursuant to Section 13.01; provided that if the Company has made any payment of
principal of, premium, if any, or interest on any Notes because of the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Notes to receive such
payment from the money or Government Securities held by the Trustee or Paying Agent.

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



        (1)    INTEREST.    MSW Energy Holdings LLC, a Delaware limited liability company ("MSW"), and MSW Energy Finance
Co., Inc., a Delaware corporation ("MSW Finance" and, together with MSW, the "Company"), promises to pay interest on the principal amount of this Note at 81/2% per annum from
June 25, 2003 until maturity and shall pay the Additional Interest, if any, payable pursuant to Section 6 of the Registration Rights Agreement referred to below. The Company will pay
interest and Additional Interest, if any, semi-annually in arrears on March 1 and September 1 of each year, 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 will 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 September 1, 2003. The Company will 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 1% per annum in excess of the rate then in effect; it will pay interest (including
post-petition interest in any proceeding under any Bankruptcy Law) on overdue installments of interest and Additional Interest, if any, (without regard to any applicable grace periods)
from time to time on demand at the same rate to the extent lawful. Interest will be computed on the basis of a 360-day year of twelve 30-day months. 


        (2)    METHOD OF PAYMENT.    The Company will pay interest on the Notes (except defaulted interest) and Additional
Interest, if any, to the Persons who are registered Holders of Notes at the close of business on the February 15 or August 15 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 2.12 of the Indenture with respect to defaulted interest. The Notes will be
payable as to principal, premium and Additional Interest, if any, and interest 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 Additional Interest, if any, may be made by check mailed to the Holders at their addresses set forth in the register of Holders;  provided that
payment by wire transfer
of immediately available funds will be required with respect to principal of and interest, premium and Additional Interest, if any, on, all Global Notes and all other Notes the Holders of which will
have provided wire transfer instructions to the Company or the Paying Agent. Such payment will 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, Wells Fargo Bank Minnesota, National Association, the Trustee under
the Indenture, will 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 AND SECURITY AGREEMENTS.    The Company issued the Notes under an Indenture dated as of
June 25, 2003 (the "Indenture") between the Company and the Trustee. 



A1-3





 




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 §§
77aaa-77bbbb). The Notes are subject to all such terms, and Holders are referred to the Indenture and such Act for a complete 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. The Notes are secured obligations of the Company. The Notes are secured by
a first priority lien on substantially all of the assets of the Company pursuant to the Pledge Agreement and the Deposit Agreement referred to in the Indenture. 


        (5)    Optional Redemption.    



        (a)   Notwithstanding
the provisions of subparagraph (a) of this Paragraph 5, at any time prior to September 1, 2006, the Company may redeem Notes with
the net proceeds of a Qualified Equity Offering at a redemption price equal to 108.5% of the aggregate principal amount thereof; provided that at least
65% in aggregate principal amount of the Notes issued under the Indenture remains outstanding immediately after the occurrence of such redemption and that such redemption occurs within 90 days
of the date of the closing of such Qualified Equity Offering. 


        (b)   At
any time prior to September 1, 2007, the Company may redeem all or a part of the Notes upon not less than 30 nor more than 60 days' notice, at a
redemption price equal to the following on the date of redemption: 



        (1)   as
determined by an Independent Investment Bank, the sum of the present values of the Remaining Scheduled Payments discounted to the redemption date on a semiannual
basis (assuming a 360 day year consisting of twelve 30-day months) at the Adjusted Treasury Rate; plus in each case, 


        (2)   accrued
and unpaid interest and Additional Interest, if any, on the notes to the applicable date of redemption. 




        (c)   At
any time on or after September 1, 2007, the Company will have the option to redeem the Notes, in whole or in part, upon not less than 30 nor more than
60 days' notice, at the redemption prices (expressed as percentages of principal amount) set forth below plus accrued and unpaid interest and Additional Interest, if any, thereon to the
applicable redemption date, if redeemed during the twelve-month period beginning on September 1 of the years indicated below: 




	Year
 
	 	Percentage
	 
	2007	 	104.250	%
	2008	 	102.125	%
	2009 and thereafter	 	100.000	%






        (6)    Special Mandatory Redemption.    


        In
accordance with the terms and conditions of the Escrow Agreement, and using the Company Deposit (as defined in the Escrow Agreement), the Company shall redeem all and not less than
all of the Notes on September 30, 2003, or such earlier date as the Company shall elect (the "Special Mandatory Redemption Date"), if the Acquisition has not occurred on or prior to the Special
Mandatory Redemption Date, at a redemption price equal to 100% of the aggregate principal amount of the Notes, plus accrued and unpaid interest thereon to, but not including, September 30,
2003. Upon the closing of the Acquisition on or before the Special Mandatory Redemption Date, the foregoing provisions of this paragraph (6) shall be null and void. 



A1-4





 




        (7)    Repurchase at Option of Holder.    



        (a)   If
there is a Change of Control, the Company will be required to make an offer (a "Change of Control Offer") to repurchase all or any part (equal to $1,000 or an
integral multiple thereof) of each Holder's Notes at a purchase price equal to 101% of the aggregate principal amount thereof plus accrued and unpaid interest and Additional Interest thereon, if any,
to the date of purchase (the "Change of Control Payment"). Within 30 days following any Change of Control, the Company will mail a notice to each Holder setting forth the procedures governing
the Change of Control Offer as required by the Indenture. 


        (b)   MSW
shall not, and shall not permit any of its Restricted Subsidiaries to, consummate an Asset Sale. 


        (c)   Within
30 days of each date on which the aggregate amount of Excess Proceeds exceeds $20 million, the Company will commence an ARC Transaction Offer to all
Holders of Notes and all holders of other Indebtedness that is pari passu with the Notes containing provisions similar to those set forth in the
Indenture pursuant to Section 3.09 of the Indenture to purchase the maximum principal amount of Notes (including any Additional Notes) and other pari
passu Indebtedness that may be purchased out of the Excess Proceeds at an offer price in cash in an amount equal to 100% of the principal amount thereof plus accrued and unpaid
interest and Additional Interest thereon, if any, to the date fixed for the closing of such offer, in accordance with the procedures set forth in the Indenture. To the extent that the aggregate amount
of Notes (including any Additional Notes) and other pari passu Indebtedness tendered pursuant to an ARC Transaction Offer is less than the Excess
Proceeds, the Company may use such deficiency for any purpose not otherwise prohibited by the Indenture. If the aggregate principal amount of Notes and other pari
passu Indebtedness surrendered by holders thereof exceeds the amount of Excess Proceeds, the Trustee shall select the Notes and other pari
passu Indebtedness to be purchased on a pro rata basis. Holders of Notes that are the subject of an offer to purchase will
receive an ARC Transaction Offer from the Company prior to any related purchase date and may elect to have such Notes purchased by completing the form entitled "Option of Holder to Elect Purchase" on
the reverse of the Notes. 




        (8)    NOTICE OF REDEMPTION.    Notice of redemption will be mailed at least 30 days but not 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
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.

such Indebtedness prior to its express maturity and the principal amount of any such Indebtedness aggregates $25.0 million or more; (vii) certain final judgments aggregating in excess of

Subsidiaries, Duke/UAE Ref-Fuel, any Subsidiary of Duke/UAE Ref-Fuel that is a Significant Subsidiary of Duke/UAE Ref-Fuel or any group of Subsidiaries
of Duke/UAE Ref Fuel that, taken as a whole, would constitute a Significant Subsidiary of Duke/UAE Ref-Fuel. If any Event of Default 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 will become due and payable without further action or notice. 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, partner, member or stockholder, of
the Company or any of the Guarantors, as such, will not have any liability for any obligations of the Company or such Guarantor under the Notes, the Note Guarantees, the Indenture, the Pledge
Agreement or the Deposit Agreement 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 will not be valid until authenticated by the manual signature of the Trustee or
an authenticating agent.

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 September 1, 2003. The Company will pay interest (including post-petition interest in any proceeding

post-petition interest in any proceeding under any Bankruptcy Law) on overdue installments of interest and Additional Interest, if any, (without regard to any applicable grace periods)
from time to time on demand at the same rate to the extent lawful. Interest will be computed on the basis of a 360-day year of twelve 30-day months. 


        Until
this Regulation S Temporary Global Note is exchanged for one or more Regulation S Permanent Global Notes, the Holder hereof shall not be entitled to receive payments
of interest hereon; until so exchanged in full, this Regulation S Temporary Global Note shall in all other respects be entitled to the same benefits as other Notes under the Indenture. 



        (2)    METHOD OF PAYMENT.    The Company will pay interest on the Notes (except defaulted interest) and Additional
Interest, if any, to the Persons who are registered Holders of Notes at the close of business on the February 15 or August 15 next preceding the Interest Payment Date, even if such Notes

for a complete 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. The Notes are secured obligations of the Company. The Notes are secured by a first priority lien on substantially all of the assets of the Company pursuant to the Pledge Agreement and the
Deposit Agreement referred to in the Indenture. 


        (5)    OPTIONAL REDEMPTION.

the provisions of subparagraph (a) of this Paragraph 5, at any time prior to September 1, 2006, the Company may redeem Notes with
the net proceeds of a Qualified Equity Offering at a redemption price equal to 108.5% of the aggregate principal amount thereof; provided that at least
65% in aggregate principal amount of the Notes issued under the Indenture remains outstanding immediately after the occurrence of such redemption and that such redemption occurs within 90 days
of the date of the closing of such Qualified Equity Offering. 


        (b)   At
any time prior to September 1, 2007, the Company may redeem all or a part of the Notes upon not less than 30 nor more than 60 days' notice, at a
redemption price equal to the following on the date of redemption: 



        (1)   as
determined by an Independent Investment Bank, the sum of the present values of the Remaining Scheduled Payments discounted to the redemption date on a semiannual
basis (assuming a 360 day year consisting of twelve 30-day months) at the Adjusted Treasury Rate; plus in each case, 


        (2)   accrued
and unpaid interest and Additional Interest, if any, on the notes to the applicable date of redemption. 




        (c)   At
any time on or after September 1, 2007, the Company will have the option to redeem the Notes, in whole or in part, upon not less than 30 nor more than
60 days' notice, at the redemption prices (expressed as percentages of principal amount) set forth below plus accrued and unpaid interest and Additional Interest, if any, thereon to the

A2-4





 

redemption
price equal to 100% of the aggregate principal amount of the Notes, plus accrued and unpaid interest thereon to, but not including, September 30, 2003. Upon the closing of the
Acquisition on or before the Special Mandatory Redemption Date, the foregoing provisions of this paragraph (6) shall be null and void. 


        (7)    REPURCHASE AT OPTION OF HOLDER.    



        (a)   If
there is a Change of Control, the Company will be required to make an offer (a "Change of Control Offer") to repurchase all or any part (equal to $1,000 or an
integral multiple thereof) of each Holder's Notes at a purchase price equal to 101% of the aggregate principal amount thereof plus accrued and unpaid interest and Additional Interest thereon, if any,
to the date of purchase (the "Change of Control Payment"). Within 30 days following any Change of Control, the Company will mail a notice to each Holder setting forth the procedures governing
the Change of Control Offer as required by the Indenture. 


        (b)   MSW
shall not, and shall not permit any of its Restricted Subsidiaries to, consummate an Asset Sale. 



        (c)   Within
30 days of each date on which the aggregate amount of Excess Proceeds exceeds $20 million, the Company will commence an ARC Transaction Offer to all
Holders of Notes and all holders of other Indebtedness that is pari passu with the Notes containing provisions similar to those set forth in the
Indenture pursuant to Section 3.09 of the Indenture to purchase the maximum principal amount of Notes (including any Additional Notes) and other pari
passu Indebtedness that may be purchased out of the Excess Proceeds at an offer price in cash in an amount equal to 100% of the principal amount thereof plus accrued and unpaid
interest and Additional Interest thereon, if any, to the date fixed for the closing of such offer, in accordance with the procedures set forth in the Indenture. To the extent that the aggregate amount
of Notes (including any Additional Notes) and other pari passu Indebtedness tendered pursuant to an ARC Transaction Offer is less than the Excess
Proceeds, the Company may use such deficiency for any purpose not otherwise prohibited by the Indenture. If the aggregate principal amount of Notes and other pari
passu Indebtedness surrendered by holders thereof exceeds the amount of Excess Proceeds, the Trustee shall select the Notes and other pari
passu Indebtedness to be purchased on a pro rata basis. Holders of Notes that are the subject of an offer to purchase will
receive an ARC Transaction Offer from the Company prior to any related purchase date and may elect to have such Notes purchased by completing the form entitled "Option of Holder to Elect Purchase" on
the reverse of the Notes. 




        (8)    NOTICE OF REDEMPTION.    Notice of redemption will be mailed at least 30 days but not 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
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

reason; (ix) failure of the Escrow Agreement, at any time, to be in full force and effect (unless the Company Deposit is released by the Escrow Agent) or any contest by the Company or any of
the Guarantors of the validity or enforceability of the Escrow Agreement; (x) except as permitted by the Indenture, any Note Guarantee shall be held in any judicial proceeding to be
unenforceable or invalid or shall cease for any reason to be in full force and effect or any Guarantor or any Person acting on its behalf shall deny or disaffirm its obligations under such Guarantor's
Note Guarantee; or (xi) certain events of bankruptcy or insolvency with respect to MSW, or any of its Restricted Subsidiaries, Duke/UAE Ref-Fuel, any Subsidiary of Duke/UAE

Subsidiary of Duke/UAE Ref-Fuel. If any Event of Default 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 will become due
and payable without further action or notice. 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, partner, member or stockholder, of
the Company or any of the Guarantors, as such, will not have any liability for any obligations of the Company or such Guarantor under the Notes, the Note Guarantees, the Indenture, the Pledge
Agreement or the Deposit Agreement 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 will not be valid until authenticated by the manual signature of the Trustee or
an authenticating agent.

with all Guarantors named in the Indenture, to jointly and severally Guarantee to each Holder of a Note authenticated and delivered by the Trustee and to the
Trustee and its successors and assigns, the Notes or the obligations of the Company hereunder or thereunder, that: 



        (i)    the
principal of, and premium and Additional Interest, if any, and interest on the Notes will be promptly paid in full when due, whether at maturity, by acceleration,
redemption or otherwise, and interest on the overdue principal of and interest on the Notes, if any, if lawful, and all other obligations of the Company to the Holders or the Trustee hereunder or
thereunder will be promptly paid in full or performed, all in accordance with the terms hereof and thereof; and 



        (ii)   in
case of any extension of time of payment or renewal of any Notes or any of such other obligations, that same will be promptly paid in full when due or performed in
accordance with the terms of the extension or renewal, whether at stated maturity, by acceleration or otherwise. Failing payment when due of any amount so guaranteed or any performance so guaranteed
for whatever reason, the Guarantors shall be jointly and severally obligated to pay the same immediately. 





F-1





 







        (b)   The
obligations hereunder shall be unconditional, irrespective of the validity, regularity or enforceability of the Notes or the Indenture, the absence of any action to
enforce the same, any waiver or consent by any Holder of the Notes with respect to any provisions hereof or thereof, the recovery of any judgment against the Company, any action to enforce the same or
any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a Guarantor. 


        (c)   The
following is hereby waived: diligence, presentment, demand of payment, filing of claims with a court in the event of insolvency or bankruptcy of the Company, any
right to require a proceeding first against the Company, protest, notice and all demands whatsoever. 


        (d)   This
Note Guarantee shall not be discharged except by complete performance of the obligations contained in the Notes and the Indenture, and the Guaranteeing Subsidiary
accepts all obligations of a Guarantor under the Indenture. 


        (e)   If
any Holder or the Trustee is required by any court or otherwise to return to the Company, the Guarantors, or any custodian, trustee, liquidator or other similar
official acting in relation to either the Company or the Guarantors, any amount paid by either to the Trustee or such Holder, this Note Guarantee, to the extent theretofore discharged, shall be
reinstated in full force and effect. 


        (f)    The
Guaranteeing Subsidiary shall not be entitled to any right of subrogation in relation to the Holders in respect of any obligations guaranteed hereby until payment in
full of all obligations guaranteed hereby. 


        (g)   As
between the Guarantors, on the one hand, and the Holders and the Trustee, on the other hand, (x) the maturity of the obligations guaranteed hereby may be
accelerated as provided in Article 6 of the Indenture for the purposes of this Note Guarantee, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect
of the obligations guaranteed hereby, and (y) in the event of any declaration of acceleration of such obligations as provided in Article 6 of the Indenture, such obligations (whether or
not due and payable) shall forthwith become due and payable by the Guarantors for the purpose of this Note Guarantee. 


        (h)   The
Guarantors shall have the right to seek contribution from any non-paying Guarantor so long as the exercise of such right does not impair the rights of
the Holders under the Note Guarantee. 


        (i)    Pursuant
to Section 11.02 of the Indenture, after giving effect to any maximum amount and all other contingent and fixed liabilities that are relevant under any
applicable Bankruptcy or fraudulent conveyance laws, and after giving effect to any collections from, rights to receive contribution from or payments made by or on behalf of any other Guarantor in
respect of the obligations of such other Guarantor under Article 10 of the Indenture, this new Note Guarantee shall be limited to the maximum amount permissible such that the obligations of
such Guarantor under this Note Guarantee will not constitute a fraudulent transfer or conveyance. 




        3.    EXECUTION AND DELIVERY.    Each Guaranteeing Subsidiary agrees that the Note Guarantees shall remain in full
force and effect notwithstanding any failure to endorse on each Note a notation of such Note Guarantee. 


        4.    GUARANTEEING SUBSIDIARY MAY CONSOLIDATE, ETC. ON CERTAIN TERMS.    



        (a)   Except
as otherwise provide in Section 11.05 of the Indenture, the Guaranteeing Subsidiary may not sell or otherwise dispose of all substantially all of its
assets to, or 




F-2





 


consolidate
with or merge with or into (whether or not such Guarantor is the surviving Person) another Person, other than the Company or another Guarantor unless: 



        (i)    immediately
after giving effect to such transaction, no Default or Event of Default exists; and 



        (ii)   the
Person acquiring the property in any such sale or disposition or the Person formed by or surviving any such consolidation or merger unconditionally assumes all the
obligations of that Guarantor, pursuant to a supplemental indenture in form and substance reasonably satisfactory to the Trustee, under the Notes, the Indenture and the Note Guarantee on the terms set
forth herein or therein. 




        (b)   In
case of any such consolidation, merger, sale or conveyance and upon the assumption by the successor Person, by supplemental indenture, executed and delivered to the
Trustee and satisfactory in form to the Trustee, of the Note Guarantee endorsed upon the Notes and the due and punctual performance of all of the covenants and conditions of the Indenture to be
performed by the Guarantor, such successor Person shall succeed to and be substituted for the Guarantor with the same effect as if it had been named herein as a Guarantor. Such successor Person
thereupon may cause to be signed any or all of the Note Guarantees to be endorsed upon all of the Notes issuable under the Indenture which theretofore shall not have been signed by the Company and
delivered to the Trustee. All the Note Guarantees so issued shall in all respects have the same legal rank and benefit under the Indenture as the Note Guarantees theretofore and thereafter issued in
accordance with the terms of the Indenture as though all of such Note Guarantees had been issued at the date of the execution hereof. 


        (c)   Except
as set forth in Articles 4 and 5 and Section 11.05 of Article 11 of the Indenture, and notwithstanding clauses (a) and (b) above,
nothing contained in the Indenture or in any of the Notes shall prevent any consolidation or merger of a Guarantor with or into the Company or another Guarantor, or shall prevent any sale or
conveyance of the property of a Guarantor as an entirety or substantially as an entirety to the Company or another Guarantor. 




        5.    RELEASES.    



        (a)   In
the event of any sale or other disposition of all or substantially all of the assets of any Guarantor, by way of merger, consolidation or otherwise, or a sale or
other disposition of all of the capital stock of any Guarantor, in each case to a Person that is not (either before or after giving effect to such
transaction) a Restricted Subsidiary of the Company, then such Guarantor (in the event of a sale or other disposition, by way of merger, consolidation or otherwise, of all of the capital stock of such
Guarantor) or the corporation acquiring the property (in the event of a sale or other disposition of all or substantially all of the assets of such Guarantor) will be released and relieved of any
obligations under its Note Guarantee. Upon delivery by the Company to the Trustee of an Officers' Certificate and an Opinion of Counsel to the effect that such sale or other disposition was made by
the Company in accordance with the provisions of the Indenture, including without limitation Section 4.10 of the Indenture, the Trustee shall execute any documents reasonably required in order
to evidence the release of any Guarantor from its obligations under its Note Guarantee. The Note Guarantee of a Guarantor shall be released upon its designation by MSW as an Unrestricted Subsidiary in
accordance with the terms of the Indenture. 


        (b)   Any
Guarantor not released from its obligations under its Note Guarantee shall remain liable for the full amount of principal of and interest on the Notes and for the
other obligations of any Guarantor under the Indenture as provided in Article 11 of the Indenture. 




F-3





 






        6.    NO RECOURSE AGAINST OTHERS.    No past, present or future director, officer, employee, incorporator, partner,
member, stockholder or agent of the Guaranteeing Subsidiary, as such, shall have any liability for any obligations of the Company or any Guaranteeing Subsidiary under the Notes, any Note Guarantees,
the Indenture or this Supplemental Indenture or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder of the Notes by accepting a Note waives and
releases all such liability. The waiver and release are part of the consideration for issuance of the Notes. Such waiver may not be effective to waive liabilities under the federal securities laws and
it is the view of the SEC that such a waiver is against public policy. 


        7.    NEW YORK LAW TO GOVERN.    THE INTERNAL LAW OF THE STATE OF NEW YORK SHALL GOVERN AND BE USED TO CONSTRUE THIS
SUPPLEMENTAL INDENTURE BUT WITHOUT GIVING EFFECT TO APPLICABLE PRINCIPLES OF CONFLICTS OF LAW TO THE EXTENT THAT THE APPLICATION OF THE LAWS OF ANOTHER JURISDICTION WOULD BE REQUIRED THEREBY. 



        8.    COUNTERPARTS.    The parties may sign any number of copies of this Supplemental Indenture. Each signed copy
shall be an original, but all of them together represent the same agreement. 


        9.    EFFECT OF HEADINGS.    The Section headings herein are for convenience only and shall not affect the
construction hereof. 


        10.    THE TRUSTEE.    The Trustee shall not be responsible in any manner whatsoever for or in respect of the validity
or sufficiency of this Supplemental Indenture or for or in respect of the recitals contained herein, all of which recitals are made solely by the Guaranteeing Subsidiary and the Company.
