                                   THE NOTES

SECTION 2.01.   FORM AND DATING.

        (a)     GENERAL. The Notes and the Trustee's certificate of
authentication shall 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 shall be dated the date of its authentication. The Notes
shall be in denominations of $1,000 and integral multiples thereof.

        The terms and provisions contained in the Notes shall 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 shall be substantially
in the form of Exhibit A 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 shall be substantially in the form of
Exhibit A 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 shall represent such of the outstanding Notes as
shall be specified therein and each shall provide that it shall represent 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 shall 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.

SECTION 2.02.   EXECUTION AND AUTHENTICATION.

        Two Officers shall sign the Notes for the Company by manual or facsimile
signature. The Company's seal shall be reproduced on the Notes and may be in
facsimile form.

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

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

        The Trustee shall, upon a written order of the Company signed by two
Officers (an "AUTHENTICATION ORDER"), authenticate Notes for original issue up
to the aggregate principal amount stated in paragraph 4 of the Notes.

        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.

office or agency where Notes may be presented for payment ("PAYING AGENT"). The
Registrar shall 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 shall notify
the Trustee in writing of the name and address of any Agent not a party to this

act as Depositary with respect to the Global Notes.

        The Company initially appoints the Trustee to act as the Registrar and
Paying Agent and to act as Custodian with respect to the Global Notes.

        The Company shall 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 Liquidated Damages, if any, or interest on the Notes, and
will notify the Trustee of any default by the Company, the Parent Guarantor or
any Subsidiary Guarantor 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) shall have no further liability for
the money. If the Company or a Subsidiary acts as Paying Agent, it shall
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 shall serve as Paying Agent for
the Notes.

SECTION 2.05.   HOLDER LISTS.

        The Trustee shall 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 Section 312(a). If the Trustee
is not the Registrar, the Company shall 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 Section 312(a).

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

                                       24

of, a Global Note or any portion thereof, pursuant to this Section 2.06 or

interests in a Global Note may be transferred and exchanged as provided in

                in the form of Exhibit B hereto, including the certifications in
                item (2) thereof; and

                        (C)     if the transfer will be made pursuant to any
                other exemption from the registration requirements of the
                Securities Act, then the transferor must deliver a certificate
                in the form of Exhibit B hereto, including the certifications,
                certificates and Opinion of Counsel required by item (3)

        NOTES. Any Restricted Definitive Note may be exchanged by the Holder
        thereof for an Unrestricted Definitive Note or transferred to a Person
        or Persons who take delivery thereof in the form of an Unrestricted
        Definitive Note if:

                        (A)     such exchange or transfer is effected pursuant
                to the Exchange Offer in accordance with the Registration Rights
                Agreement and the Holder, in the case of an exchange, or the
                transferee, in the case of a transfer, certifies in the
                applicable Letter of Transmittal that it is not (1) a
                broker-dealer, (2) a Person participating in the distribution of
                the Exchange Notes or (3) a Person who is an affiliate (as
                defined in Rule 144) of the Company;

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

                        (C)     any such transfer is effected by a Broker-Dealer

                        (D)     the Registrar receives the following:

                                (1)     if the Holder of such Restricted
                        Definitive Notes proposes to exchange such Notes for an
                        Unrestricted Definitive Note, a certificate from such
                        Holder in the form of Exhibit C hereto, including the
                        certifications in item (1)(d) thereof; or

                                (2)     if the Holder of such Restricted
                        Definitive Notes proposes to transfer such Notes to a
                        Person who shall take delivery thereof in the form of an
                        Unrestricted Definitive Note, a certificate from such
                        Holder in the form of Exhibit B hereto, including the
                        certifications in item (4) thereof;

                and, in each such case set forth in this subparagraph (D), if
                the Registrar so requests, an Opinion of Counsel in form
                reasonably acceptable to the Company to the effect that such
                exchange or transfer is in compliance with the Securities Act
                and that the restrictions on transfer contained herein and in
                the Private Placement Legend are no longer required in order to
                maintain compliance with the Securities Act.

                (iii)   UNRESTRICTED DEFINITIVE NOTES TO UNRESTRICTED DEFINITIVE
        NOTES. A Holder of Unrestricted Definitive Notes may transfer such Notes
        to a Person who takes delivery thereof in the form of an Unrestricted
        Definitive Note. Upon receipt of a request to register such a transfer,
        the Registrar shall register the Unrestricted Definitive Notes pursuant
        to the instructions from the Holder thereof.

        (f)     EXCHANGE OFFER. Upon the occurrence of the Exchange Offer in
accordance with the Registration Rights Agreement, the Company shall issue and,

Trustee shall authenticate (i) one or more Unrestricted Global Notes in an
aggregate principal amount equal to the principal amount of the beneficial
interests in the Restricted Global Notes tendered for acceptance by Persons that
certify in the applicable Letters of Transmittal that (x) they are not
broker-dealers, (y) they are not participating in a distribution of the Exchange
Notes and (z) they are not affiliates (as defined in Rule 144) of the Company,
and accepted for exchange in the Exchange Offer and (ii) Definitive Notes in an

Definitive Notes accepted for exchange in the Exchange Offer. Concurrently with
the issuance of such Notes, the Trustee shall cause the aggregate principal
amount of the applicable Restricted Global Notes to be reduced accordingly, and
the Company shall execute and the Trustee shall authenticate and deliver to the
Persons designated by the Holders of Definitive Notes so accepted Definitive
Notes in the appropriate principal amount.

        (g)     LEGENDS. The following legends shall appear on the face of all
Global Notes and Definitive Notes issued under this Indenture unless
specifically stated otherwise in the applicable provisions of this Indenture.

                (i)     PRIVATE PLACEMENT LEGEND.

                        (A)     Except as permitted by subparagraph (B) below,
                each Global Note and each Definitive Note (and all Notes issued
                in exchange therefor or substitution thereof) shall bear the
                legend in substantially the following form

"THIS NOTE HAS NOT BEEN REGISTERED UNDER THE U.S. SECURITIES ACT OF 1933, AS

                        (B)     Notwithstanding the foregoing, any Global Note
                or Definitive Note issued pursuant to subparagraphs (b)(iv),
                (c)(iii), (c)(iv), (d)(ii), (d)(iii), (e)(ii), (e)(iii) or (f)
                to this Section 2.06 (and all Notes issued in exchange therefor
                or substitution thereof) shall not bear the Private Placement
                Legend.

                (ii)    GLOBAL NOTE LEGEND. Each Global Note shall bear a legend
        in substantially the following form:

"THIS GLOBAL NOTE IS HELD BY THE DEPOSITARY (AS DEFINED IN THE INDENTURE
GOVERNING THIS NOTE) OR ITS NOMINEE IN CUSTODY FOR THE BENEFIT OF THE BENEFICIAL
OWNERS HEREOF, AND IS NOT TRANSFERABLE TO ANY PERSON UNDER ANY CIRCUMSTANCES
EXCEPT THAT (I) THE TRUSTEE MAY MAKE SUCH NOTATIONS HEREON AS MAY BE REQUIRED
PURSUANT TO SECTION 2.07 OF THE INDENTURE, (II) THIS GLOBAL NOTE MAY BE
EXCHANGED IN WHOLE BUT NOT IN PART PURSUANT TO SECTION 2.06(a) OF THE INDENTURE,
(III) THIS GLOBAL NOTE MAY BE DELIVERED TO THE TRUSTEE FOR CANCELLATION PURSUANT
TO SECTION 2.11 OF THE INDENTURE AND (IV) THIS GLOBAL NOTE MAY BE TRANSFERRED TO
A SUCCESSOR DEPOSITARY WITH THE PRIOR WRITTEN CONSENT OF THE COMPANY."

        (h)     CANCELLATION AND/OR ADJUSTMENT OF GLOBAL NOTES. At such time as
all beneficial interests in a particular Global Note have been exchanged for
Definitive Notes or a particular Global Note has been redeemed, repurchased or
canceled in whole and not in part, each such Global Note shall be returned to or
retained and canceled by the Trustee in accordance with Section 2.11 hereof. At
any time prior to such cancellation, if any beneficial interest in a Global Note
is exchanged for or transferred to a Person who will take delivery thereof in
the form of a beneficial interest in another Global Note or for Definitive
Notes, the principal amount of Notes represented by such Global Note shall be
reduced accordingly and an endorsement shall be made on such Global Note by the
Trustee or by the Depositary at the direction of the Trustee to reflect such
reduction; and if the beneficial interest is being exchanged for or transferred
to a Person who will take delivery thereof in the form of a beneficial interest
in another Global Note, such other Global Note shall be increased accordingly
and an endorsement shall be made on such Global Note by the Trustee or by the
Depositary at the direction of the Trustee to reflect such increase.

        (i)     GENERAL PROVISIONS RELATING TO TRANSFERS AND EXCHANGES.

                (i)     To permit registrations of transfers and exchanges, the
        Company shall execute and the Trustee shall authenticate Global Notes
        and Definitive Notes upon the Company's order or at the Registrar's
        request.

                (ii)    No service charge shall be made to a holder of a
        beneficial interest in 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, 4.14 and 9.05
        hereof).

                (iii)   The Registrar shall 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.

                (iv)    All Global Notes and Definitive Notes issued upon any
        registration of transfer or exchange of Global Notes or Definitive Notes
        shall be the valid obligations of the Company,

                                       34
<Page>

        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.

                (v)     The Company shall 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 mailing a
        notice of redemption of Notes for 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 so 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.

                (vi)    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.

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

                (viii)  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 shall issue and the Trustee, upon receipt of an
Authentication Order, shall authenticate a replacement Note if the Trustee's
requirements are met. 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
shall 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 a Subsidiary 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 bona fide purchaser.

                                       35
<Page>

        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 shall be deemed to be no longer outstanding and shall cease to accrue
interest.

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, by the Parent Guarantor, by any Subsidiary Guarantor or by any Person
directly or indirectly controlling or controlled by or under direct or indirect
common control with the Company, the Parent Guarantor or such Subsidiary
Guarantor, shall be considered as though not outstanding, except that for the
purposes of determining whether the Trustee shall be protected in relying on any
such direction, waiver or consent, only Notes that a Responsible Officer of the
Trustee actually knows are so owned shall 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,
shall authenticate temporary Notes. Temporary Notes shall be substantially in
the form of certificated Notes but may have variations that the Company
considers appropriate for temporary Notes and as shall be reasonably acceptable
to the Trustee. Without unreasonable delay, the Company shall prepare and the
Trustee shall authenticate definitive Notes in exchange for temporary Notes.

        Holders of temporary Notes shall 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 shall forward to the Trustee any
Notes surrendered to them for registration of transfer, exchange or payment. The
Trustee and no one else shall cancel all Notes surrendered for registration of
transfer, exchange, payment, replacement or cancellation and shall dispose of
canceled Notes in accordance with its customary procedures. 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 shall
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 shall 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 shall fix or cause to be fixed each such
special record date and payment date, PROVIDED that no such special record date
shall 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) shall 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.

                                       36
<Page>

SECTION 2.13.   CUSIP NUMBERS.

        The Company in issuing the Notes may use "CUSIP" numbers (if then
generally in use), and, if so, the Trustee shall use "CUSIP" numbers in notices
of redemption as a convenience to Holders; PROVIDED that any such notice may
state that no representation is made as to the correctness of such numbers
either as printed on the Notes or as contained in any notice of a redemption and
that reliance may be placed only on the other identification numbers printed on
the Notes, and any such redemption shall not be affected by any defect in or
omission of such numbers. The Company will promptly notify the Trustee of any
change in the "CUSIP" numbers.

                                   ARTICLE 3.
                            REDEMPTION AND PREPAYMENT

SECTION 3.01.   NOTICES TO TRUSTEE.

        If the Company elects to redeem Notes pursuant to the optional
redemption provisions of Section 3.07 hereof, it shall furnish to the Trustee,
at least 30 days but not more than 60 days before a redemption date, an
Officers' Certificate setting forth (i) the clause of this Indenture pursuant to
which the redemption shall occur, (ii) the redemption date, (iii) the principal
amount of Notes to be redeemed and (iv) the redemption price.

SECTION 3.02.   SELECTION OF NOTES TO BE REDEEMED.

        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 as
follows:

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

        (2)     if the Notes are not so listed, on a pro rata basis, by lot
                or in accordance with any other method the Trustee considers
                fair and appropriate.

        Notes and portions of Notes selected will be in amounts of $1,000 or
whole multiples of $1,000, except that if all Notes of a Holder are to be
redeemed, the entire amount of Notes held by such Holder, even if not a multiple
of $1,000, will be redeemed. Notices of redemption shall be mailed by first
class mail at least 10 but not more than 60 days before the redemption date to
each Holder of Notes to be redeemed at its registered address. Notices of
redemption may not be conditional.

        If any Note is to be redeemed in part only, the notice of redemption
that relates to that Note shall state the portion of the principal amount
thereof to be redeemed. An Exchange Note in principal amount equal to the
unredeemed portion of the original Note will be issued in the name of the Holder
thereof upon cancellation of the original Note. Notes called for redemption
become due on the date fixed for redemption at the redemption price. On and
after the redemption date, interest ceases to accrue on Notes or portions of
them called for redemption.

SECTION 3.03.   NOTICE OF REDEMPTION.

        Subject to the provisions of Section 3.09 hereof, at least 30 days but
not more than 60 days before a redemption date, the Company shall 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.

                                       37
<Page>

        The notice shall identify the Notes to be redeemed (including CUSIP
number) and shall state:

        (a)     the redemption date;

        (b)     the redemption price;

        (c)     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 shall be issued upon cancellation of the original Note;

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

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

        (f)     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;

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

        (h)     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.

        At the Company's request, the Trustee shall give the notice of
redemption in the Company's name and at its expense; PROVIDED, HOWEVER, that the
Company shall have 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 PRICE.

        One Business Day prior to the redemption date, the Company shall deposit
with the Trustee or with the Paying Agent money sufficient to pay the redemption
price of and accrued interest on all Notes to be redeemed on that date. The
Trustee or the Paying Agent shall 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 price of, and accrued interest on, all
Notes to be redeemed.

        If the Company complies with the provisions of the preceding paragraph,
on and after the redemption date, interest shall cease to accrue on the Notes or
the portions of Notes called for redemption. If a Note is redeemed 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

Offer. Payment for any Notes so purchased shall be made in the same manner as

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 shall be payable to
Holders who tender Notes pursuant to the Asset Sale Offer.

        Upon the commencement of an Asset Sale Offer, the Company shall send, by
first class mail, a notice to the Trustee and each of the Holders, with a copy
to the Trustee. The notice shall contain all instructions and materials
necessary to enable such Holders to tender Notes pursuant to the Asset Sale
Offer. The Asset Sale Offer shall be made to all Holders. The notice, which

Note accepted for payment pursuant to the Asset Sale Offer shall cease to
accrete or accrue interest after the Purchase Date;

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

        (f)     that Holders electing to have a Note purchased pursuant to any
Asset Sale Offer shall 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;

        (g)     that Holders shall 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 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;

        (h)     that, if the aggregate principal amount of Notes surrendered by
Holders exceeds the Offer Amount, the Company shall select the Notes to be
purchased on a PRO RATA basis (with such adjustments as may be deemed
appropriate by the Company so that only Notes in denominations of $1,000, or
integral multiples thereof, shall be purchased); and

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

or if less than the Offer Amount has been tendered, all Notes tendered, and
shall 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, shall 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 shall promptly issue a new Note, and the
Trustee, upon written request from the Company shall 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
shall publicly announce the results of the Asset Sale Offer on the Purchase
Date.

        Other than as specifically provided in this Section 3.09, any purchase

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.

refundings, replacements or refinancings thereof, PROVIDED that such amendments,
modifications, restatements, renewals, increases, supplements, refundings,

Person, so acquired, PROVIDED that, in the case of Indebtedness, such
Indebtedness was permitted by the terms of this Indenture to be incurred;

real property mortgages or related documents entered into in the ordinary course
of business and consistent with past practices;

SECTION 4.09.   INCURRENCE OF INDEBTEDNESS AND ISSUANCE OF PREFERRED STOCK.

        The Company 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 Company shall not issue any Disqualified Stock; PROVIDED, HOWEVER,
that the Company may incur Indebtedness or issue Disqualified Stock and a
Subsidiary Guarantor may incur Acquired Debt if the ratio of Total Consolidated
Indebtedness to Adjusted Consolidated Operating Cash Flow for the Company's 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 is issued would have been at
less than or equal to 6.0 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 had been issued, as
the case may be, at the beginning of such four-quarter period.

        The provisions of the first paragraph of this Section 4.09 shall not
apply to the incurrence of any of the following items of Indebtedness
(collectively, "PERMITTED DEBT"):

                (i)     the incurrence by the Company or any Subsidiary
        Guarantor of Pari Passu Indebtedness or Satellite Vendor Indebtedness in
        an aggregate principal amount (including the aggregate principal amount
        of all Permitted Refinancing Indebtedness incurred to refund, refinance
        or replace any Indebtedness incurred pursuant to this clause (i)), which
        does not exceed: (a) $500.0 million plus (b) the amount equal to 125% of
        Total Incremental Equity as of the date of such incurrence;

                (ii)    unsecured subordinated Indebtedness or Disqualified
        Stock of the Company incurred to finance the construction, expansion,
        development or acquisition of music libraries and other recorded music
        programming, furniture, fixtures and equipment (including satellites,
        ground stations and related equipment) if such subordinated Indebtedness
        or Disqualified Stock, as applicable, has a Weighted Average Life to
        Maturity longer than the Weighted Average Life to Maturity of the Notes
        and has a final Stated Maturity of principal later than the Stated
        Maturity of principal of the Notes;

                (iii)   unsecured subordinated Indebtedness or Disqualified
        Stock of the Company in an aggregate principal amount (or liquidation
        preference, as applicable) (including the aggregate principal amount (or
        liquidation preference, as applicable) of all Permitted Refinancing
        Indebtedness incurred to refund, refinance or replace any Indebtedness
        or Disqualified Stock, as applicable, incurred pursuant to this clause
        (iii)) at any time outstanding not to exceed the product of (a) $100.0
        and (b) the number of Subscribers at such time if such subordinated
        Indebtedness or Disqualified Stock, as applicable, has a Weighted
        Average Life to Maturity longer than the

                                       47
<Page>

        Weighted Average Life to Maturity of the Notes and has a final Stated
        Maturity of principal later than the Stated Maturity of principal of the
        Notes;

                (iv)    the incurrence by the Company and its Restricted
        Subsidiaries of the Existing Indebtedness and the incurrence by the
        Company and the Restricted Subsidiaries of the Company of Indebtedness
        pursuant to the January 2003 Financing Transactions;

                (v)     the incurrence by the Company and any Subsidiary
        Guarantors of Indebtedness represented by the Notes and any Subsidiary
        Guarantees thereof and the Exchange Notes and any Subsidiary Guarantees
        thereof to be issued pursuant to the Registration Rights Agreement;

                (vi)    the incurrence by the Company or any of its Restricted
        Subsidiaries (other than XM Leasing) of Indebtedness represented by
        Capital Lease Obligations, mortgage financings or purchase money
        obligations, in each case, incurred for the purpose of financing all or
        any part of the purchase price or cost of acquisition, construction or
        improvement of property, plant or equipment used in the business of the
        Company or such Subsidiary, in an aggregate principal amount, including
        all Permitted Refinancing Indebtedness incurred to refund, refinance or
        replace any Indebtedness incurred pursuant to this clause (vi), not to
        exceed $30.0 million at any time outstanding;

                (vii)   the incurrence by the Company or any Subsidiary
        Guarantors or any of its Restricted Subsidiaries, as applicable, 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 the first paragraph of this covenant or clauses (i),
        (ii), (iii), (iv), (v), (vi), (vii), (xii), (xiii) or (xiv) of this
        paragraph;

                (viii)  the incurrence by the Company or any of its Restricted
        Subsidiaries other than XM Leasing of intercompany Indebtedness between
        or among the Company and any of its Restricted Subsidiaries; PROVIDED,
        HOWEVER, that: (a) if the Company 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; and (b) (i)
        any subsequent issuance or transfer of Equity Interests that results in
        any such Indebtedness being held by a Person other than the Company or a
        Restricted Subsidiary thereof (other than XM Leasing) and (ii) any sale
        or other transfer of any such Indebtedness to a Person that is not
        either the Company or a Restricted Subsidiary (other than XM Leasing)
        thereof; shall be deemed, in each case, to constitute an incurrence of
        such Indebtedness by the Company or such Restricted Subsidiary (other
        than XM Leasing), as the case may be, that was not permitted by this
        clause (viii);

                (ix)    the incurrence by the Company of Hedging Obligations
        that are incurred for the purpose of fixing or hedging (x) interest rate
        risk with respect to any floating rate Indebtedness that is permitted by
        the terms of this Indenture to be outstanding or (y) fluctuation in
        currency values;

                (x)     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;

                                       48
<Page>

                (xi)    the incurrence by the Company of additional Indebtedness
        (including Acquired Debt) or Disqualified Stock in an aggregate
        principal amount (or liquidation preference or accreted value, as
        applicable) at any time outstanding, including all Permitted Refinancing
        Indebtedness incurred to refund, refinance or replace any Indebtedness
        or Disqualified Stock incurred pursuant to this clause (xi), not to
        exceed $30.0 million;

                (xii)   Indebtedness the proceeds of which are utilized solely
        to finance working capital in an aggregate principal amount not to
        exceed the lesser of (a) $50.0 million and (b) 80% of Qualified
        Receivables;

                (xiii)  from and after any Parent Company Merger, Indebtedness
        of Holdings in existence on the date hereof;

                (xiv)   any Qualified Sale and Leaseback Transaction; and

                (xv)    any Indebtedness of XM Leasing when taken together with
        all amounts permitted by Clause (14) of the definition of "Permitted
        Investments" not exceeding $5.0 million outstanding at any time.

        The Company will not incur any Indebtedness (including Permitted Debt)
that is contractually subordinated in right of payment to any other Indebtedness
of the Company 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 Company shall be deemed to be contractually
subordinated in right of payment to any other Indebtedness of the Company solely
by virtue of being unsecured.

        For purposes of determining compliance with this Section 4.09, in the
event that an item of Indebtedness meets the criteria of more than one of the
categories of Permitted Debt described in clauses (i) through (xv) above or is
entitled to be incurred pursuant to the first paragraph of this Section 4.09,
the Company shall, in its sole discretion, classify such item of Indebtedness in
any manner that complies with this Section 4.09 and such item of Indebtedness
shall be treated as having been incurred pursuant to only one of such clauses or
pursuant to the first paragraph of this Section 4.09.

SECTION 4.10.   ASSET SALES.

        The Company shall not, and shall not permit any of its Restricted
Subsidiaries to consummate an Asset Sale unless (x) the Company (or the
Restricted Subsidiary, as the case may be) receives consideration at the time of
such Asset Sale at least equal to the fair market value of the assets or Equity
Interests issued or sold or otherwise disposed of; (y) such fair market value
shall be determined by the Company's Board of Directors (whose good faith
determination shall be conclusive) and evidenced by a Board Resolution set forth
in an Officers' Certificate delivered to the Trustee; and (z) at least 75% of
the consideration received therefor by the Company or such Restricted Subsidiary
is in the form of cash or Cash Equivalents.

        For purposes of this provision, each of the following shall be deemed to
be cash:

        (a)     any liabilities (as shown on the Company's or such Restricted
                Subsidiary's most recent balance sheet or in the notes thereto)
                of the Company or any Restricted Subsidiary (other than
                contingent liabilities and liabilities that are by their terms
                subordinated to the notes or any guarantee thereof) that are
                assumed by the transferee of any such assets pursuant to a

                                       49
<Page>

                customary novation agreement that releases the Company or such
                Restricted Subsidiary from further liability; and

        (b)     any securities, notes or other obligations received by the
                Company or any such Restricted Subsidiary from such transferee
                that are converted by the Company or such Restricted Subsidiary
                into cash (to the extent of the cash received in that
                conversion) within 30 days of the receipt thereof.

        Any Restricted Payment that is permitted by Section 4.07 hereof will not
be deemed to be an Asset Sale.

        Within 360 days after the receipt of any Net Proceeds from an Asset
Sale, the Company may (a) apply the Net Proceeds from such Asset Sale, at its
option, (i) to acquire all or substantially all of the assets of, or a majority
of the Voting Stock of, another Permitted Business, or Voting Stock of a
Restricted Subsidiary engaged in a Permitted Business (other than any such
Voting Stock owned or held by a Restricted Subsidiary), (ii) to make a capital
expenditure, or (iii) to acquire other assets that are used or useful in a
Permitted Business that have an expected useful life of one year or longer; (b)
enter into a legally binding agreement to apply such Net Proceeds as described
in the preceding clause (a) within six months after such agreement is entered
into and apply such Net Proceeds in accordance with the terms of such agreement
or the provisions of clause (a) above; provided that if such agreement
terminates the Company shall have until the earlier of (i) 90 days after the
date of such termination and (ii) six months after the date of the Asset Sale
resulting in such Net Proceeds to effect such an application; or (c) to
permanently repay (and reduce the commitments with respect to) Pari Passu
Indebtedness. Pending the final application of any such Net Proceeds, the
Company may temporarily reduce revolving credit borrowings or otherwise invest
such Net Proceeds in any manner that is not prohibited by this Indenture. Any
Net Proceeds from such Asset Sale that are not finally applied or invested as
provided in the first sentence of this paragraph will be deemed to constitute
"EXCESS PROCEEDS." Within five days of each date on which the aggregate amount
of Excess Proceeds exceeds $10 million, the Company shall commence an Asset Sale
Offer pursuant to Section 3.09 hereof to all Holders of Notes and all holders of
Pari Passu Indebtedness 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, or if applicable,
accreted value, of notes and such other PARI PASSU Indebtedness that may be
purchased out of the Excess Proceeds. The offer price in any Asset Sale Offer
will be equal to 100% of the principal amount (or accreted value, if applicable,
of such Indebtedness plus accrued and unpaid interest of any Liquidated Damages,
if any) to the date fixed for the closing of such offer, in accordance with the
procedures set forth in Section 3.09 hereof. If any Excess Proceeds remain after
consummation of an Asset Sale Offer, the Company may use such Excess Proceeds
for any purpose not otherwise prohibited by the indenture. If the aggregate
principal amount of notes and principal amount (or, if applicable, accreted
value) of such other PARI PASSU Indebtedness tendered into such Asset Sale Offer
exceeds the amount of Excess Proceeds, the Trustee shall select the Notes and
such other PARI PASSU Indebtedness to be purchased on a pro rata basis based on
the principal amount (or, if applicable, accreted value) of Notes and such other
PARI PASSU Indebtedness tendered. Upon completion of each Asset Sale Offer, the
amount of Excess Proceeds shall be deemed to be reset at zero.

        The Company shall comply with the requirements of Rule 14e-1 under the
Exchange Act and any other securities laws and regulations thereunder to the
extent such laws and regulations are applicable in connection with each
repurchase of Notes pursuant to an Asset Sale Offer. To the extent that the
provisions of any securities laws or regulations conflict with the Asset Sales
provisions of this Indenture, the Company shall comply with the applicable
securities laws and regulations and shall not be deemed to have breached its
obligations under the Asset Sale provisions of this Indenture by virtue of such
conflict.

SECTION 4.11.   TRANSACTIONS WITH AFFILIATES.

        The Company shall not, and shall not permit any of its Restricted
Subsidiaries to, make any payment to, or sell, lease, transfer or otherwise
dispose of any of its properties or assets to, or purchase any property or
assets from, or enter into or make or amend any transaction, contract,
agreement, understanding, loan, advance or guarantee with, or for the benefit
of, any Affiliate (each, an "AFFILIATE TRANSACTION"), unless: (a) such Affiliate
Transaction is on terms that are no less favorable to the Company or the
relevant Restricted Subsidiary than those that would have been obtained in a
comparable transaction by the Company or such Restricted Subsidiary with an
unrelated Person; and (b) the Company delivers to the Trustee (i) with respect
to any Affiliate Transaction or series of related Affiliate Transactions
involving aggregate consideration in excess of $5.0 million, a resolution of the
Board of Directors set forth in an Officers' Certificate certifying that such
Affiliate Transaction complies with this covenant and, if an opinion meeting the
requirements set forth in clause (ii) of this paragraph has not been obtained,
that such Affiliate Transaction has been approved by a majority of the members
of the Board of Directors who have no direct financial interest in such
Affiliate Transaction other than as a stockholder of the Company or Holdings and
(ii) with respect to (x) any Affiliate Transaction or series of related
Affiliate Transactions involving aggregate consideration in excess of $20.0
million, or (y) any Affiliate Transaction or series of related Affiliate
Transactions involving aggregate consideration in excess of $5.0 million where
none of the members of the Board of Directors qualify as having no direct
financial interest in such Affiliate Transaction (other than as a stockholder of
the Company or Holdings), an opinion as to the fairness to the Company or such
Restricted Subsidiary of such Affiliate Transaction from a financial point of
view issued by an accounting, appraisal or investment banking firm of national
standing; PROVIDED HOWEVER that the following items shall not be deemed to be
Affiliate Transactions and, therefore, will not be subject to the provisions of
this paragraph:

        (1)     any transaction by the Company or any Restricted Subsidiary with
an Affiliate directly related to the purchase, sale or distribution of products
in the ordinary course of business consistent with industry practice which has
been approved by a majority of the members of the Board of Directors who are
disinterested with respect to such transaction;

        (2)     any employment agreement or arrangement or employee benefit plan
entered into by the Company or any of its Restricted Subsidiaries in the
ordinary course of business of the Company or such Restricted Subsidiary;

        (3)     transactions between or among the Company and/or its Restricted
Subsidiaries;

        (4)     payment of reasonable directors fees and provisions of customary
indemnification to directors, officers and employees of the Company and its
Restricted Subsidiaries;

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

        (6)     Restricted Payments that are permitted by the provisions of
Section 4.07 hereof and under clauses (8) and (9) of the definition of
"Permitted Investments";

        (7)     transactions pursuant to the Tax Sharing Agreement;

        (8)     contractual arrangements existing on the date hereof, and any
renewals, extensions, implementations or modifications thereof that are not
materially adverse to the Holders;

        (9)     the January 2003 Financing Transactions; and

                                       51
<Page>

        (10)    the Parent Company Merger.

SECTION 4.12.   LIENS.

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

SECTION 4.13.   CORPORATE EXISTENCE.

        Subject to Article 5 hereof, the Company, the Parent Guarantor and each
Subsidiary Guarantor shall use its reasonable best efforts to preserve and keep
in full force and effect (i) its corporate existence, and the corporate,
partnership or other existence of each of its Subsidiaries, in accordance with
the respective organizational documents (as the same may be amended from time to
time) of the Company, the Parent Guarantor, each Subsidiary Guarantor or any
such Subsidiary and (ii) the rights (charter and statutory), licenses and
franchises of the Company, the Parent Guarantor, each Subsidiary Guarantor and
any such Subsidiaries; PROVIDED, HOWEVER, that the Company, the Parent Guarantor
and the Subsidiary Guarantors shall not be required to preserve any such right,
license or franchise, or the corporate, partnership or other existence of any of
its Subsidiaries, if the Board of Directors shall determine that the
preservation thereof is no longer desirable in the conduct of the business of
the Company, the Parent Guarantor, each Subsidiary Guarantor and any such
Subsidiaries, taken as a whole, and that the loss thereof is not adverse in any
material respect to the Holders of the Notes, PROVIDED, however, that nothing in
this Section 4.13 shall prohibit a Parent Company Merger.

SECTION 4.14.   OFFER TO REPURCHASE UPON CHANGE OF CONTROL.

        (a)     Upon the occurrence of a Change of Control, the Company 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 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 Liquidated Damages thereon, if
any) to the date of purchase (the "CHANGE OF CONTROL PAYMENT"). Within 30 days
following any Change of Control, the Company shall mail a notice to each Holder
stating: (1) that the Change of Control Offer is being made pursuant to this
Section 4.14 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 and no
later than 60 calendar 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 Company defaults in the payment of the Change of
Control Payment, all Notes accepted for payment pursuant to the Change of
Control Offer shall 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;
(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 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 Company
shall comply with the requirements of Rule 14e-1 under the Exchange Act and any
other securities laws and regulations thereunder to the extent such laws and
regulations are applicable in connection with the repurchase of Notes in
connection with a Change of Control. To the extent that the

                                       52
<Page>

provisions of any securities laws or regulations conflict with the Change of
Control provisions of this Indenture, the Company will comply with the
applicable securities laws and regulations and will not be deemed to have
breached its obligations under the Change of Control provisions of this
Indenture by virtue of such conflict.

        (b)     On the Change of Control Payment Date, the Company 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 thereof so 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 thereof being purchased by the
Company. The Paying Agent shall promptly mail to each Holder of Notes so
tendered the Change of Control Payment for such Notes, and the Trustee shall
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 by such Holder, if any; PROVIDED, that each such new Note
shall be in a principal amount of $1,000 or an integral multiple thereof. The
Company 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)     The Company 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

SECTION 4.18.   INSURANCE

        (a)     The Company shall obtain prior to the launch of each satellite
and shall maintain launch insurance with respect to each satellite launch
covering the period from the launch to 180 days following the launch of each
satellite in an amount equal to or greater than the sum of (1) the cost to
replace such satellite with a satellite of comparable or superior technological
capability (as determined by the Board of Directors, whose determination shall
be conclusive and evidenced by a Board Resolution) and having at least as much
transmission capacity as the satellite to be replaced, (2) the cost to launch a
replacement satellite pursuant to the contract whereby a replacement satellite
will be launched and (3) the cost of launch insurance for such replacement or,
in the event that the Company has reason to believe that the cost of obtaining
comparable insurance for a replacement would be materially higher, the Company's
best estimate of the cost of such comparable insurance in each case such costs
being determined as of the date such insurance is procured by the Board of
Directors whose determination shall be conclusive and evidenced by a Board
Resolution). Notwithstanding the foregoing, at any time when the Company has two
primary satellites in-orbit and fully functioning, the Company shall not be
obligated to obtain insurance pursuant to this paragraph (a) with respect to the
launch of any satellite that the Company does not intend to use as a replacement
for one of the satellites used by the Company to provide the XM Radio Service.

        (b)     The Company shall maintain full in-orbit insurance with respect
to each satellite it owns and launches in an amount at least equal to the sum of
(1) the cost to replace such satellite with a satellite of comparable or
superior technological capability (as determined by the Board of Directors,
whose determination shall be conclusive and evidenced by a Board Resolution) and
having at least as much transmission capacity as the satellite to be replaced
(or such percentage of replacement value as is then reasonably obtainable in the
insurance market at a commercially reasonable cost), (2) the cost to launch a
replacement satellite pursuant to the contract pursuant to which a replacement
satellite will be launched and (3) the cost of launch insurance for such
replacement or, in the event that the Company has reason to believe that the
cost of obtaining comparable insurance for a replacement would be materially
higher, the Company's best estimate of the cost of such comparable insurance
(provided, however, that with respect to any satellite as to which there has
been an insured loss, the required amount of such insurance shall equal the
lesser of such sum and the amount reasonably obtainable in the insurance market
at a

                                       54
<Page>

commercially reasonable cost, as determined by the Board of Directors whose
determination shall be conclusive and evidenced by a Board Resolution). The
in-orbit insurance required by this paragraph shall provide that if 50% or more
of a satellite's capacity is lost, the full amount of insurance shall become due
and payable, and that if a satellite is able to maintain more than 50% but less
than 100% of its capacity, a portion of such insurance shall become due and
payable.

        (c)     In the event that the Company receives proceeds from insurance
relating to any satellite, the Company shall be entitled to use all or any
portion of such proceeds for any purpose, including (1) to repay any vendor or
third-party purchase money financing pertaining to such satellite that is
required to be repaid by reason of the loss giving rise to such insurance
proceeds, (2) to develop and construct a replacement satellite; or (3) general
corporate purposes

of the Company in accordance with Section 5.01 hereof, the successor corporation
formed by such consolidation or into or with which the Company is merged or to

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 the "Company" shall refer instead to
the successor corporation and not to the Company), and may exercise every right
and power of the Company under this Indenture with the same effect as if such
successor Person had been named as the Company herein; PROVIDED, HOWEVER, that
the predecessor Company shall not be relieved from the obligation to pay the
principal of and interest on the Notes except in the case of a sale, assignment,

                                       55

SECTION 6.01.   EVENTS OF DEFAULT AND REMEDIES.

Liquidated Damages with respect to, the Notes and such default continues for 30
days;

        (b)     the Company defaults in the payment when due of principal of or

Notes, if any) then outstanding voting as a single class;

        (e)     a default occurs under any mortgage, indenture or instrument
under which there may be issued or by which there may be secured or evidenced
any Indebtedness for money borrowed by the Company or any of its Restricted
Subsidiaries (or the payment of which is guaranteed by the Company or any of its
Restricted Subsidiaries), whether such Indebtedness or guarantee now exists, or
is created after the date hereof, which default results in the acceleration of
such Indebtedness prior to its express maturity or is caused by a failure to pay
principal of, or interest or premium, if any, on such Indebtedness prior to the
expiration of the grace period provided in such Indebtedness on the date of such
default (a "Payment Default") and, in each case, the principal amount of such

shall not be effectively stayed) of 60 days, PROVIDED that the aggregate of all
such undischarged judgments exceeds $10.0 million (net of any amounts with
respect to which a reputable and creditworthy insurance company has acknowledged
liability in writing);

        (g)     the Company or any of its Significant Subsidiaries or any group
of Subsidiaries that, taken as a whole, would constitute a Significant
Subsidiary pursuant to or within the meaning of Bankruptcy Law:

        whole, would constitute a Significant Subsidiary in an involuntary case;

                (ii)    appoints a custodian of the Company or any of its
        Significant Subsidiaries or any group of Subsidiaries that, taken as a

        substantially all of the property of the Company or any of its
        Significant Subsidiaries or any group of Subsidiaries that, taken as a
        whole, would constitute a Significant Subsidiary; or

                (iii)   orders the liquidation of the Company or any of its
        Significant Subsidiaries or any group of Subsidiaries that, taken as a

Guarantee.

SECTION 6.02.   ACCELERATION.

        In the case of an Event of Default specified in clause (g) or (h) of
Section 6.01 hereof with respect to the Company, any Significant Subsidiary or
any group of Subsidiaries that, taken as a whole, would constitute a Significant
Subsidiary, the principal amount of 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. Holders of the Notes may not enforce this Indenture
or the Notes except as provided herein. Except where such (x) would conflict
with applicable law or this Indenture or (y) may involve the Trustee in personal
liability (for which the Trustee has not been indemnified as provided in this
Indenture), Holders of a majority in principal amount of outstanding Notes may
direct the Trustee in its exercise of any trust 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
amount, premium or interest) if it determines that withholding notice is in
their interest. The

                                       57
<Page>

Holders of not less than a majority in aggregate principal amount of the Notes
then outstanding by notice to the Trustee may on behalf of all of the Holders
waive any existing Default or Event of Default and its consequences hereunder
except a continuing Default or Event of Default in the payment of interest or
Liquidated Damages on, or the principal amount of, the Notes.

        In the case of any Event of Default occurring by reason of any willful
action (or inaction) taken (or not taken) by or on behalf of the Company with
the intention of avoiding payment of the premium that the Company would have had
to pay if the Company then had elected to redeem the Notes pursuant to Section
3.07 hereof, an equivalent premium shall also become and be immediately due and
payable, to the extent permitted by law upon the acceleration of the principal
amount of the Notes. If an Event of Default occurs prior to June 15, 2007 by
reason of any willful action (or inaction) taken (or not taken) by or on behalf
of the Company with the intention of avoiding the prohibition on redemption of
the Notes prior to such date, then the premium specified herein shall also
become immediately due and payable to the extent permitted by law upon the
acceleration of the principal amount of the Notes.

        The Company is required to deliver to the Trustee annually an Officer's
Certificate regarding compliance herewith. Upon becoming aware of any Default or
Event of Default, the Company is required to deliver to the Trustee an Officer's
Certificate specifying such Default or Event of Default.

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 Liquidated
Damages, 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 Liquidated Damages, 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 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.

                                       58
<Page>

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:

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

        (b)     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;

        (c)     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;

        (d)     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

        (e)     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 of a Note to receive payment of principal, premium and Liquidated
Damages, if any, and interest on the Note, on or after the respective due dates
expressed in the Note (including in connection with an offer to purchase), 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(a) or (b) 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, the Parent Guarantor or any
Subsidiary Guarantor for the whole amount of principal of, premium and
Liquidated Damages, 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.

                                       59
<Page>

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 obligor upon the Notes), its creditors or its property and shall
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, 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 Liquidated Damages, 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
        Liquidated Damages, 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 and expenses, 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 does not apply to a suit by the Trustee, a suit by a
Holder of a Note

SECTION 7.01.   DUTIES OF TRUSTEE.

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

                (i)     the duties of the Trustee shall 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

                (ii)    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, in the case of any such certificates or opinions
        which by any provision hereof are specifically required to be furnished
        to the Trustee, the Trustee shall be under a duty to examine the same to
        determine whether or not they conform to the requirements of this
        Indenture (but need not confirm or investigate the accuracy of
        mathematical calculations or other facts stated therein).

        (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:

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

                (ii)    the Trustee shall 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

                (iii)   the Trustee shall 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.

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

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 shall 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

action taken, suffered or omitted by it hereunder in good faith and in reliance
thereon.

and liabilities that might be incurred by it in compliance with such request or
direction.

        (g)     The Trustee shall not be deemed to have notice of any Default or
Event of Default unless a Responsible Officer of the Trustee has actual
knowledge thereof or unless written notice of any event which is in fact such a
default is received by the Trustee at the Corporate Trust Office of the Trustee,
and such notice references the Notes and this Indenture.

        (h)     The rights, privileges, protections, immunities and benefits
given to the Trustee, including, without limitation, its right to be
indemnified, are extended to, and shall be enforceable by, the Trustee in each
of its capacities hereunder, and each agent, custodian and other Person employed
to act hereunder.

        (i)     The Trustee may request that the Company deliver an Officers'
Certificate setting forth the names of individuals and/or titles of officers

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 the Company or any Affiliate of
the Company 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. The Trustee is also subject to Sections 7.10 and 7.11 hereof.

SECTION 7.04.   TRUSTEE'S DISCLAIMER.

        The Trustee shall not be responsible for and makes no representation as
to the validity or adequacy of this Indenture or the Notes, it 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, it shall not be responsible for the use or application of any money
received by any Paying Agent other than the Trustee, and it shall 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 shall 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, 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.

        Within 60 days after each May 15 beginning with the May 15 following the
date hereof, and for so long as Notes remain outstanding, the Trustee shall mail
to the Holders of the Notes a brief report dated as of such reporting date that
complies with TIA Section 313(a) (but if no event described in TIA Section
313(a) has occurred within the twelve months preceding the reporting date, no
report need be transmitted). The Trustee also shall comply with TIA Section
313(b)(2). The Trustee shall also transmit by mail all reports as required by
TIA Section 313(c).

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

SECTION 7.07.   COMPENSATION AND INDEMNITY.

        The Company shall pay to the Trustee from time to time such compensation
for its acceptance of this Indenture and services hereunder as shall be agreed
in writing from time to time between the Company and the Trustee. The Trustee's
compensation shall not be limited by any law on compensation of a trustee of an
express trust. The Company shall 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 shall include the
reasonable compensation, disbursements and expenses of the Trustee's agents and
counsel.

                                       63
<Page>

        The Company shall indemnify the Trustee against any and all losses,
liabilities or expenses incurred by it arising out of or in connection with the
acceptance or administration of its duties under this Indenture, including the
reasonable costs and expenses of enforcing this Indenture against the Company
(including this Section 7.07) and defending itself against any claim (whether
asserted by the Company 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 shall notify the
Company promptly of any claim for which it may seek indemnity. Failure by the
Trustee to so notify the Company shall not relieve the Company of its
obligations hereunder. The Company shall defend the claim and the Trustee shall
cooperate in the defense. The Trustee may have separate counsel and the Company
shall pay the reasonable fees and expenses of such counsel. The Company need not
pay for any settlement made without its consent, which consent shall not be
unreasonably withheld.

satisfaction and discharge of this Indenture.

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

        When the Trustee incurs expenses or renders services after an Event of
Default specified in Section 6.01(g) or (h) 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.

the extent applicable.

SECTION 7.08.   REPLACEMENT OF TRUSTEE.

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

        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:

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

        (b)     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;

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

        (d)     the Trustee becomes incapable of acting.

        If the Trustee resigns or is removed or if a vacancy exists in the
office of Trustee for any reason, the Company shall 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.

                                       64
<Page>

        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, at the expense of the Company, any court of competent jurisdiction
for the appointment of a successor Trustee.

        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.

        A successor Trustee shall deliver a written acceptance of its
appointment to the retiring Trustee and to the Company. Thereupon, the
resignation or removal of the retiring Trustee shall become effective, and the
successor Trustee shall have all the rights, powers and duties of the Trustee
under this Indenture. The successor Trustee shall mail a notice of its
succession to Holders. The retiring Trustee shall 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 shall 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 shall be the successor
Trustee.

SECTION 7.10.   ELIGIBILITY; DISQUALIFICATION.

        There shall 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 shall always have a Trustee who satisfies the
requirements of TIA Section 310(a)(1), (2) and (5). The Trustee is subject to
TIA Section 310(b).

SECTION 7.11.   PREFERENTIAL COLLECTION OF CLAIMS AGAINST COMPANY.

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

                                       65
<Page>

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, the Parent Guarantor and the
Subsidiary Guarantors shall, 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 on the date the conditions set
forth below are satisfied (hereinafter, "LEGAL DEFEASANCE"). For this purpose,
Legal Defeasance means that the Company, the Parent Guarantor and the Subsidiary
Guarantors shall be deemed to have paid and discharged the entire Indebtedness
represented by the outstanding Notes, which shall 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 (a) and (b) below, and to have
satisfied all its other obligations under such Notes 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
shall survive until otherwise terminated or discharged hereunder: (a) the rights
of Holders of outstanding Notes to receive solely from the trust fund described
in Section 8.04 hereof, and as more fully set forth in such Section, payments in
respect of the aggregate principal amount of, premium, if any, and interest on
such Notes when such payments are due, (b) the Company's, the Parent Guarantor's
and the Subsidiary Guarantors' obligations with respect to such Notes under
Article 2 and Section 4.02 hereof, (c) the rights, powers, trusts, duties and
immunities of the Trustee hereunder and the Company's, the Parent Guarantor's
and the Subsidiary Guarantors' obligations in connection therewith and (d) this
Article Eight. Subject to compliance with this Article Eight, 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 shall, subject to the satisfaction
of the conditions set forth in Section 8.04 hereof, be released from its
obligations under the covenants contained in Sections 3.09, 4.07, 4.08, 4.09,
4.10, 4.11, 4.12, 4.14, 4.15, 4.16, 4.17 and 4.18 hereof and clause (iv) of
Section 5.01 hereof with respect to the outstanding Notes on and after the date
the conditions set forth in Section 8.04 are satisfied (hereinafter, "COVENANT
DEFEASANCE"), and the Notes shall 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 shall
continue to be deemed "outstanding" for all other purposes hereunder (it being
understood that such Notes shall not be deemed outstanding for accounting
purposes). For this purpose, Covenant Defeasance means that, with respect to the
outstanding Notes, the Company 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 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(c) through 6.01(f) hereof shall not constitute Events of Default.

SECTION 8.04.   CONDITIONS TO LEGAL OR COVENANT DEFEASANCE.

        The following shall be the conditions to the application of either
Section 8.02 or 8.03 hereof to the outstanding Notes:

<Page>

        (a)     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 aggregate principal amount of, or interest and premium,
if any, on the outstanding Notes on the Stated Maturity or on the applicable
redemption date, as the case may be, and the Company must specify whether the
Notes are being defeased to maturity or to a particular redemption date;

        (b)     in the case of an election under Section 8.02 hereof, the
Company shall have delivered 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 hereof, 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;

        (c)     in the case of an election under Section 8.03 hereof, the
Company shall have delivered 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;

        (d)     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 incurrence of Indebtedness all or a portion of the proceeds
of which will be used to defease the Notes pursuant to this Article Eight
concurrently with such incurrence) or insofar as Sections 6.01(g) or 6.01(h)
hereof is concerned, at any time in the period ending on the 91st day after the
date of deposit;

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

        (f)     the Company shall have delivered to the Trustee an Opinion of
Counsel (which may be subject to customary exceptions including, but not limited
to the assumption that there is no intervening bankruptcy of the Company between
the date of deposit and the 91st day following the deposit and the assumption
that no Holder is an "insider" of the Company under applicable bankruptcy law)
to the effect that on the 91st day following the deposit, the trust funds will
not be subject to the effect of any applicable bankruptcy, insolvency,
reorganization or similar laws affecting creditors' rights generally;

        (g)     the Company shall have delivered to the Trustee an Officers'
Certificate stating that the deposit was not made by the Company with the intent
of preferring the Holders over any other creditors of the Company or with the
intent of defeating, hindering, delaying or defrauding any other creditors of
the Company; and

        (h)     the Company shall have delivered to the Trustee an Officers'
Certificate and an Opinion of Counsel, each stating that all conditions
precedent provided for or relating to the Legal Defeasance or the Covenant
Defeasance have been complied with.

        Anything in this Article Eight to the contrary notwithstanding, the
Trustee shall deliver or pay to the Company from time to time upon the written
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(a) 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.

Securities (including the proceeds thereof) deposited with the Trustee (or other
qualifying trustee, collectively for purposes of this Section 8.05, the

shall 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 aggregate principal amount, premium and
Liquidated Damages, if any, and interest, but such money need not be segregated
from other funds except to the extent required by law.

        The Company shall 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.

        Anything in this Article Eight to the contrary notwithstanding, the
Trustee shall 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(a) 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 aggregate principal amount of,
premium, if any, or interest on any Note and remaining unclaimed for two years
after such aggregate principal amount, and premium, 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) shall be discharged from such trust; and the Holder of such

liability of the Trustee or such Paying Agent with respect to such trust money,
and all liability of the Company as trustee thereof, shall 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 shall 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 any Guarantors' obligations under this
Indenture, the Notes and the Indenture Guarantees shall 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 aggregate principal
amount of, premium and Liquidated Damages, if any, or interest on any Note
following 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 held by the Trustee or Paying Agent.

        (d)     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

authorizing the execution of any such amended or supplemental Indenture,
Indenture Guarantee, Security Agreement or Intercreditor Agreement and upon
receipt by the Trustee of the documents described in Section 7.02 hereof, the

SECTION 9.02.   WITH CONSENT OF HOLDERS OF NOTES.

        Except as provided below in this Section 9.02, the Company, the Parent
Guarantor, the Subsidiary Guarantors and the Trustee may amend or supplement
this Indenture (including Section 3.09, 4.10 and 4.14 hereof), the Notes, the
Indenture Guarantees, either of the Security Agreements and either of the
Intercreditor Agreements with the consent of the Holders of at least a majority
in principal amount at maturity of the Notes (including 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 (other than a Default or Event of Default
in the payment of the principal of, premium, if any, or interest on the Notes,
except a payment default resulting from an acceleration that has been rescinded)
or compliance with any provision of this Indenture, the Notes, the Indenture
Guarantees, either of the Security Agreements or either of the Intercreditor
Agreements may be waived with the consent of the Holders of a majority in
principal amount at maturity of the then outstanding Notes (including Additional
Notes, if any) voting as a single class (including consents obtained in
connection with a tender offer or exchange offer for, or purchase of, the
Notes). Notwithstanding anything to the contrary contained in the Indenture,
each of the Security Agreements may also be amended pursuant to the terms of the
applicable Intercreditor Agreement without the consent of the Holders of at
least a majority in principal amount at maturity of the Notes.

        Upon the request of the Company, the Parent Guarantor and the Subsidiary
Guarantors accompanied by a resolution of each of their Boards of Directors
authorizing the execution of any such amended or supplemental Indenture,
Indenture Guarantee, Security Agreement or Intercreditor Agreement, and upon the
filing with the Trustee of evidence satisfactory to the Trustee of the consent
of the Holders of Notes as aforesaid, if necessary, and upon receipt by the
Trustee of the documents described in Section 7.02 hereof, the Trustee shall
join with the Company, the Parent Guarantor and the Subsidiary Guarantors in the
execution of (or, in the case of any Security Agreement, directing the
Collateral Agent to execute) such amended or supplemental Indenture, Indenture
Guarantee, Security Agreement or Intercreditor Agreement unless such amended or
supplemental Indenture, Indenture Guarantee, Security Agreement or Intercreditor
Agreement 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 shall not be obligated to, enter into (or, if applicable, direct the
Collateral Agent to enter into) such amended or supplemental Indenture,
Indenture Guarantee, Security Agreement or Intercreditor Agreement.

        It shall not be 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 shall be sufficient if such consent approves the substance
thereof.

        After an amendment, supplement or waiver under this Section becomes
effective, the Company shall 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, shall 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 at maturity of the Notes (including
Additional Notes, if any) then outstanding voting as a single class may waive

                                       70
<Page>

compliance in a particular instance by the Company with any provision of this
Indenture or the Notes. However, 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):

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

        (b)     reduce the principal amount 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
4.14 hereof;

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

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

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

        (f)     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, if any, on the Notes;

        (g)     waive a redemption payment with respect to any Note other than a
payment required by Sections 3.09, 4.10 and 4.14 hereof;

        (h)     release any portion of the Collateral from the Lien of the
Security Agreements, except in accordance with the terms thereof;

        (i)     release any Guarantor from its Obligations under the Indenture
or its Indenture Guarantee except as in accordance therewith; or

        (j)     make any change in Section 6.04 or 6.07 hereof or in the
foregoing amendment and waiver provisions.

SECTION 9.03.   COMPLIANCE WITH TRUST INDENTURE ACT.

        Every amendment or supplement to this Indenture or the Notes shall be
set forth in a 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,

                                       71
<Page>

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 shall not
affect the validity and effect of such amendment, supplement or waiver.

SECTION 9.06.   TRUSTEE TO SIGN AMENDMENTS, ETC.

        The Trustee shall sign any amended or supplemental Indenture, Indenture
Guarantee, Security Agreement or Intercreditor Agreement authorized pursuant to
this Article Nine if the amendment or supplement does not adversely affect the
rights, duties, liabilities or immunities of the Trustee. Each of the Company,
the Parent Guarantor and the Subsidiary Guarantors may not sign an amendment or
supplemental Indenture, Indenture Guarantee, Security Agreement or Intercreditor
Agreement until its Board of Directors approves it. In executing any amended or
supplemental Indenture, Indenture Guarantee, Security Agreement or Intercreditor
Agreement, the Trustee shall receive and (subject to Section 7.01 hereof) shall
be fully protected in relying upon, in addition to the documents required by
Section 13.04 hereof, an Officers' Certificate and an Opinion of Counsel stating
that the execution of such amended or supplemental Indenture, Indenture
Guarantee, Security Agreement or Intercreditor Agreement is authorized or
permitted by this Indenture.

constituted, so as to render the same available for the security and benefit of

<Page>

        (c)     The release of any Collateral from the terms of this Indenture

impair the security under this Indenture and the Liens in favor of the
Collateral Agent on the remaining Collateral in contravention of the provisions
hereof if and to the extent the Collateral is released pursuant to the terms of
the Security Agreements and the Intercreditor Agreements. To the extent
applicable, the Company shall cause TIA Section 313(b), relating to reports, and
TIA Section 314(d), relating to the release of property or securities from the

certificate or opinion be made by an independent Person, which Person shall be
an independent engineer, appraiser or other expert selected or approved by the

conclusive evidence of compliance with the foregoing provisions the appropriate
statements contained in such documents.

received all documentation required by TIA Section 314(d) in connection with
such release and, based on such determination, shall deliver a certificate to
the Collateral Agent setting forth such determination.

                SECURITY AGREEMENTS AND THE INTERCREDITOR AGREEMENTS.

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 (a) enforce any of the
terms of the Security Agreements and the Intercreditor Agreements and (b)
collect and receive any and all amounts payable in respect of the Obligations of
the Company, the Parent Guarantor or any Subsidiary Guarantor hereunder. The
Trustee shall 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 Security Agreements, the
Intercreditor Agreements 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

                                       74
<Page>

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).

        Any action taken by the Trustee under either of the Intercreditor
Agreements with the vote or consent of the Holders of at least a majority in
aggregate principal amount of the Notes (including Additional Notes, if any)
shall constitute an action taken on behalf of all Holders for purposes of
determining the Required Secured Parties (as defined in such Intercreditor
Agreement) or otherwise calculating the amount of indebtedness approving or
consenting to a particular matter under such Intercreditor Agreement.

Indenture and the Notes, or upon Legal Defeasance, the Trustee shall, at the
request of the Company, deliver a certificate to the Collateral Agent in
accordance with Section 3.4 of the Intercreditor Agreements stating that such

                                   ARTICLE 11.
                              INDENTURE GUARANTEES

SECTION 11.01.  INDENTURE GUARANTEES.

        Subject to the provisions of this Article 11, the Parent Guarantor and
each Subsidiary Guarantor, jointly and severally, hereby unconditionally and
irrevocably guarantees to each Holder of a Note authenticated and delivered by
the Trustee and to the Trustee and its successors and assigns, that: (a) the
aggregate principal amount of, and premium and Liquidated Damages, if any, and
interest on the Notes will be duly and punctually paid in full when due, whether
at maturity, by acceleration or otherwise, and interest on overdue aggregate
principal amount of, and premium if any, and (to the extent permitted by law)
interest on any interest, if any, on the Notes and all other obligations of the

full or performed, all in accordance with the terms hereof and thereof; and (b)
in case of any extension of time of payment or renewal of any Notes or any of
such other obligations the 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 failing performance of any other obligation of the
Company to the Holders, for whatever reason, the Parent Guarantor and each
Subsidiary Guarantor will be obligated to pay or to perform or to cause the
performance of, the same immediately. An Event of Default under this Indenture
or the Notes shall constitute an event of default under this Indenture
Guarantee, and shall entitle the Holders of Notes to accelerate the obligations
of the Parent Guarantor and each Subsidiary Guarantor hereunder in the same
manner and to the same extent as the obligations of the Company. The Parent
Guarantor and the Subsidiary Guarantors each hereby agrees that its obligations
hereunder shall be 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

                                       75
<Page>

to any thereof, the entry 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 the Parent Guarantor or a Subsidiary
Guarantor. The Parent Guarantor and the Subsidiary Guarantors each hereby waives
and relinquishes: (a) any right to require the Trustee or the Holders (each, a
"BENEFITTED PARTY") to proceed against the Restricted Subsidiaries, the Company,
or any other Person or to proceed against or exhaust any security held by a
Benefitted Party at any time or to pursue any other remedy in any secured
party's power before proceeding against the Parent Guarantor or the Subsidiary
Guarantors; (b) any defense that may arise by reason of the incapacity, lack of
authority, death or disability of any other Person or Persons or the failure of
a Benefitted Party to file or enforce a claim against the estate (in
administration, bankruptcy or any other proceeding) of any other Person or
Persons; (c) demand, protest and notice of any kind (except as expressly
required by this Indenture), including but not limited to notice of the
existence, creation or incurring of any new or additional Indebtedness or
obligation or of any action or non-action on the part of the Parent Guarantor,
the Subsidiary Guarantors, the Company, the Restricted Subsidiaries, any
Benefitted Party, any creditor of the Parent Guarantor, the Subsidiary
Guarantors, the Company or the Restricted Subsidiaries or on the part of any
other Person whomsoever in connection with any obligations the performance of
which are hereby guaranteed; (d) any defense based upon an election of remedies
by a Benefitted Party, including but not limited to an election to proceed
against the Parent Guarantor or the Subsidiary Guarantors for reimbursement; (e)
any defense based upon any statute or rule of law which provides that the
obligation of a surety must be neither larger in amount nor in other respects
more burdensome than that of the principal; (f) any defense arising because of a
Benefitted Party's election, in any proceeding instituted under the Bankruptcy
Law, of the application of Section 1111 (b)(2) of the Bankruptcy Code; and (g)
any defense based on any borrowing or grant of a security interest under Section
364 of the Bankruptcy Code. The Parent Guarantor and the Subsidiary Guarantors
each hereby covenant that this Indenture Guarantee will not be discharged except
by payment in full of all principal, premium, if any, and interest on the Notes
and all other costs provided for under this Indenture, or as provided in
Sections 12.01 and 11.04.

        If any Holder or the Trustee is required by any court or otherwise to
return to either the Company, the Parent Guarantor or the Subsidiary Guarantors,
or any custodian, trustee, or similar official acting in relation to the
Company, the Parent Guarantor or the Subsidiary Guarantors, any amount paid by
the Company, the Parent Guarantor or the Subsidiary Guarantors to the Trustee or
such Holder, the Indenture Guarantees, to the extent theretofore discharged,
shall be reinstated in full force and effect. The Parent Guarantor and the
Subsidiary Guarantors each 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. The Parent
Guarantor and the Subsidiary Guarantors each agrees that, as between it, on the
one hand, and the Holders of Notes and the Trustee, on the other hand, (x) the
maturity of the obligations guaranteed hereby may be accelerated as provided in
Article 6 hereof for the purposes hereof, notwithstanding any stay, injunction
or other prohibition preventing such acceleration in respect of the obligations
guaranteed hereby, and (y) in the event of any acceleration of such obligations
as provided in Article 6 hereof, such obligations (whether or not due and
payable) shall forthwith become due and payable by the Parent Guarantor and such
Subsidiary Guarantor for the purpose of this Indenture Guarantee.

SECTION 11.02.  EXECUTION AND DELIVERY OF INDENTURE GUARANTEES.

        To evidence the Indenture Guarantees set forth in Section 11.01 hereof,
the Parent Guarantor and the Subsidiary Guarantors each agrees that a notation
of the Indenture Guarantees substantially in the form included in Exhibit G
shall be endorsed on each Note authenticated and delivered by the Trustee and
that this Indenture shall be executed on behalf of the Parent Guarantor and each
of the Subsidiary Guarantors by the Chairman of the Board, any Vice Chairman,
the President or one of the Vice Presidents

                                       76
<Page>

of the Parent Guarantor or such Subsidiary Guarantor, as applicable, under a
facsimile of its seal reproduced on this Indenture and attested to by an Officer
other than the Officer executing this Indenture.

        The Parent Guarantor and the Subsidiary Guarantors each agrees that the
Indenture Guarantees set forth in this Article 11 will remain in full force and
effect and apply to all the Notes notwithstanding any failure to endorse on each
Note a notation of the Indenture Guarantees..

        If an Officer whose facsimile signature is on a Note no longer holds
that office at the time the Trustee authenticates the Note on which the
Indenture Guarantees are endorsed, the Indenture Guarantees shall be valid
nevertheless.

        The delivery of any Note by the Trustee, after the authentication
thereof hereunder, shall constitute due delivery of the Indenture Guarantees set
forth in this Indenture on behalf of the Parent Guarantor and each of the
Subsidiary Guarantors.

SECTION 11.03.  SUBSIDIARY GUARANTORS MAY CONSOLIDATE, ETC. ON CERTAIN TERMS.

        (a)     Nothing contained in this Indenture or in the Notes shall
prevent any consolidation or merger of a Subsidiary Guarantor with or into the
Company or another Subsidiary Guarantor, or shall prevent the transfer of all or
substantially all of the assets of a Subsidiary Guarantor to the Company or
another Subsidiary Guarantor. Upon any such consolidation, merger, transfer or
sale, the Indenture Guarantee of such Subsidiary Guarantor shall no longer have
any force or effect.

        (b)     Nothing contained in this Indenture or in any of the Notes shall
prevent any consolidation or merger of a Subsidiary Guarantor with or into a
corporation or corporations other than the Company or another Subsidiary
Guarantor (whether or not affiliated with the Subsidiary Guarantor), or
successive consolidations or mergers in which a Subsidiary Guarantor or its
successor or successors shall be a party or parties, or shall prevent the
transfer of all or substantially all of the assets of a Subsidiary Guarantor, to
a corporation other than the Company or another Subsidiary Guarantor (whether or
not affiliated with the Subsidiary Guarantor) authorized to acquire and operate
the same; PROVIDED, HOWEVER, that, except as provided in Section 11.04, each
Subsidiary Guarantor hereby covenants and agrees that, upon any such
consolidation, merger or transfer, the Indenture Guarantee endorsed on the
Notes, and the due and punctual performance and observance of all of the
covenants and conditions of this Indenture to be performed by such Subsidiary
Guarantor, shall be expressly assumed (in the event that the Subsidiary
Guarantor is not the surviving corporation in the merger), by a supplemental
indenture satisfactory in form to the Trustee, executed and delivered to the
Trustee, by the corporation formed by such consolidation, or into which the
Subsidiary Guarantor shall have been merged, or by the corporation which shall
have acquired such property. In case of any such consolidation, merger or
transfer of assets and upon the assumption by the successor corporation, by
supplemental indenture, executed and delivered to the Trustee and satisfactory
in form to the Trustee, of the Indenture 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 Subsidiary Guarantor, such successor
corporation shall succeed to and be substituted for the Subsidiary Guarantor
with the same effect as if it had been named herein as a Subsidiary Guarantor.
Such successor corporation thereupon may cause to be signed any or all of the
Indenture 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 Indenture Guarantees so issued shall in all respects have the
same legal rank and benefit under this Indenture as the Indenture Guarantees
theretofore and thereafter issued in accordance with the terms of this Indenture
as though all of such Indenture Guarantees had been issued at the date of the
execution hereof.

receive an Officers' Certificate and an Opinion of Counsel as conclusive
evidence that any such consolidation, merger, sale or conveyance, and any such
assumption of Obligations, comply with the provisions of this Section 11.03.
Such certificate and opinion shall comply with the provisions of Section 13.05.

SECTION 11.04.  RELEASES FOLLOWING SALE OF ASSETS.

        Concurrently with any sale of all or substantially all of the assets of
any Subsidiary Guarantor or all of the Capital Stock of any Subsidiary
Guarantor, in each case, in compliance with the terms hereof, then such
Subsidiary Guarantor (in the event of a sale or other disposition of all of the
Capital Stock of such Subsidiary 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 a Subsidiary Guarantor) shall be released from and relieved
of its obligations under its Indenture Guarantee or Section 11.03 hereof, as the
case may be; PROVIDED that in the event of an Asset Sale, the Net Proceeds from
such sale or other disposition are treated in accordance with the provisions of
Section 4.10 hereof. Upon delivery by the Company to the Trustee of an Officers'
Certificate and Opinion of Counsel, to the effect that such sale or other
disposition was made by the Company in accordance with the provisions of this
Indenture, including without limitation Section 4.10 hereof, the Trustee shall
execute any documents reasonably required in order to evidence the release of
any Subsidiary Guarantor from its obligations under its Indenture Guarantee. Any
Subsidiary Guarantor not released from its obligations under its Indenture
Guarantee shall remain liable for the full amount of principal of and interest
on the Notes and for the other obligations of any Subsidiary Guarantor under the
Indenture as provided in this Article 11.

Subsidiary of the Company at any time on or after the date hereof to reasonably
promptly become a Subsidiary Guarantor hereunder.

        (b)     If the Company is required to cause a Subsidiary to become a
Subsidiary Guarantor pursuant to clause (a) of this Section 11.05, the Company
shall cause such Subsidiary to (1) execute and deliver to the Trustee a
supplemental indenture in form and substance reasonably satisfactory to the
Trustee pursuant to which such Subsidiary shall unconditionally Guarantee all of
the Company's Obligations under the Notes on the terms set forth in this
Indenture, (2) execute and deliver to the Trustee the General Security Agreement
(or an accession or joinder agreement thereto) in form and substance reasonably
satisfactory to the Trustee and (3) deliver to the Trustee an Opinion of Counsel
reasonably satisfactory to the Trustee that such supplemental indenture has been
duly executed and delivered by such Subsidiary.

SECTION 11.06.  LIMITATION OF PARENT GUARANTOR'S AND SUBSIDIARY GUARANTOR'S
                LIABILITY.

        Each of the Parent Guarantor and the Subsidiary Guarantors, and by its
acceptance hereof each Holder, hereby confirms that it is the intention of all
such parties that the guarantee by the Parent Guarantor or such Subsidiary
Guarantor, as applicable, pursuant to its Indenture Guarantee not constitute a
fraudulent transfer or conveyance for purposes of the Bankruptcy Law, the
Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any
similar federal or state law. To effectuate the foregoing intention, the
Holders, the Parent Guarantor and each Subsidiary Guarantor hereby irrevocably
agree that the obligations of the Parent Guarantor and each Subsidiary Guarantor
under this Article 11 shall be limited to the maximum amount as will, after
giving effect to all other contingent and fixed liabilities of the Parent
Guarantor or such Subsidiary Guarantor, as applicable, and after giving effect
to any collections from or payments made by or on behalf of the Parent Guarantor
or any other

such other Subsidiary Guarantor under this Article 11, result in the obligations
of the Parent Guarantor or such Subsidiary Guarantor under the Indenture
Guarantee of the Parent Guarantor or such Subsidiary Guarantor not constituting
a fraudulent transfer or conveyance.

SECTION 11.07.  APPLICATION OF CERTAIN TERMS AND PROVISIONS TO THE PARENT
                GUARANTOR AND THE SUBSIDIARY GUARANTORS.

        (a)     For purposes of any provision of this Indenture that provides
for the delivery by the Parent Guarantor or any Subsidiary Guarantor of an
Officers' Certificate and/or an Opinion of Counsel, the definitions of such
terms in Section 1.01 shall apply to the Parent Guarantor or such Subsidiary
Guarantor, as applicable, as if references therein to the Company were
references to the Parent Guarantor or such Subsidiary Guarantor, respectively.

        (b)     Any request, direction, order or demand that by any provision of
this Indenture is to be made by the Parent Guarantor or any Subsidiary

required or permitted to be given or served by the Trustee or by the holders of
Notes to or on the Parent Guarantor or any Subsidiary Guarantor may be given or
served as described in Section 13.02 as if references therein to Company were

        (d)     Upon any demand, request or application by the Parent Guarantor
or any Subsidiary Guarantor to the Trustee to take any action under this
Indenture, the Parent Guarantor or such Subsidiary Guarantor, as applicable,

Section 13.04 as if all references therein to the Company were references to the
Parent Guarantor or such Subsidiary Guarantor, as applicable

                           SATISFACTION AND DISCHARGE

SECTION 12.01.  SATISFACTION AND DISCHARGE.

        This Indenture will be discharged and will cease to be of further effect
as to all Notes and Indenture Guarantees 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 making
                of a notice of redemption or otherwise or will become due and
                payable within one year and the Company 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

                                       79
<Page>

                of interest, to pay and discharge the entire indebtedness on the
                Notes not delivered to the Trustee for cancellation for
                principal, premium, Liquidated Damages, if any, and accrued
                interest to the date of maturity or redemption;

(2)     no Default or Event of Default shall have occurred and be continuing on
        the date of such deposit or shall occur as a result of such deposit
        (other than a Default or Event of Default resulting from the borrowing
        of funds to be applied to 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 is a party or by which the Company or
        any Guarantor is bound;

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

(4)     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 shall
have been deposited with the Trustee pursuant to subclause (b) of clause (1) of
this Section, the provisions of Section 11.02 and Section 8.06 shall survive.

SECTION 12.02.  APPLICATION OF TRUST MONEY.

        Subject to the provisions of Section 8.06, all money deposited with the
Trustee pursuant to Section 11.01 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 11.01 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 obligations under this Indenture and the Notes shall be revived and
reinstated as though no deposit had occurred pursuant to Section 11.01; 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 shall have the meanings assigned to them
in the Indenture referred to below unless otherwise indicated.

        1. INTEREST. XM Satellite Radio Inc., a Delaware corporation (the
"Company"), promises to pay interest on the principal amount of this Note at 12%
per annum from June 17, 2003 until maturity and shall pay the Liquidated Damages
payable pursuant to Section 5 of the Registration Rights Agreement referred to
below. The Company will pay interest and Liquidated Damages semi-annually in
arrears on December 15 and June 15, 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 December 15, 2003. The Company shall
pay interest (including post-petition interest in any proceeding under any
Bankruptcy Law) on overdue principal and premium, if any, from time to time on
demand at a rate that is 1% per annum in excess of the rate then in effect; it
shall pay interest (including post-petition interest in any proceeding under any
Bankruptcy Law) on overdue installments of interest and Liquidated Damages, 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 Liquidated Damages to the Persons who are registered
Holders of Notes at the close of business on the December 1 or June 1 next
preceding the Interest Payment Date, even if such Notes are canceled after such
record date and on or before such Interest Payment Date, except as provided in
Section 2.12 of the Indenture with respect to defaulted interest. The Notes will
be payable as to principal, premium and Liquidated Damages, 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 Liquidated Damages, if any, may be made by check mailed
to the Holders at their addresses set forth in the register of Holders, and
PROVIDED that payment by wire transfer of immediately available funds will be
required with respect to principal of and interest, premium and Liquidated
Damages, if any, on, all Global Notes and all other Notes the Holders owning
$1.0 million or more in aggregate principal amount thereof which shall have
provided wire transfer instructions to the Company or the Paying Agent. Such
payment shall be in such coin or currency of the United States of America as at
the time of payment is legal tender for payment of public and private debts.

        3. PAYING AGENT AND REGISTRAR. Initially, The Bank of New York, 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 17, 2003 ("Indenture") between the Company and the
Trustee. The terms of the Notes

                                       A-2
<Page>

include those stated in the Indenture and those made part of the Indenture by
reference to the Trust Indenture Act of 1939, as amended (15 U.S. Code Sections
77aaa-77bbbb). The Notes are subject to all such terms, and Holders are referred
to the Indenture and such Act for a statement of such terms. To the extent any
provision of this Note conflicts with the express provisions of the Indenture,
the provisions of the indenture shall govern and be controlling. The Notes are
secured obligations of the Company limited to $175 million in aggregate
principal amount, plus amounts, if any, issued to pay Liquidated Damages on
outstanding Notes as set forth in Paragraph 2 hereof. The Notes are secured by a
pledge of the Collateral pursuant to the Security Agreements referred to in the
Indenture.

        (a) Except as set forth in subparagraph (b) of this Paragraph 5, the
Company shall not have the option to redeem the Notes prior to June 15, 2007.

prices (expressed as percentages of principal amount) set forth below plus
accrued and unpaid interest and Liquidated Damages thereon to the applicable

        2009 and thereafter........................... .....      100.00%
</Table>

        (b) At any time prior to June 15, 2006, the Company may on any one or
more occasions redeem an amount of the aggregate principal amount of Notes
issued under the Indenture at a redemption price of 112% of the principal amount
thereof, plus accrued and unpaid interest and Liquidated Damages, if any, to the
redemption date, with the net cash proceeds of one or more equity offerings by
the Company or parent corporation of the Company the net proceeds of which are
contributed to the common equity of the Company (other than an offering of
Disqualified Stock); PROVIDED that at least $100.0 million of the aggregate
principal amount of the Notes issued under this Indenture remains outstanding
immediately after the occurrence of such redemption (excluding Notes held by the
Company and its subsidiaries) and that such redemption occurs within 90 days of
the date of the closing of such equity offering.

        6. MANDATORY REDEMPTION.

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

        7. REPURCHASE AT OPTION HOLDER.

        (a) If there is a Change of Control, the Company shall 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 Liquidated Damages thereon, if any, to the date of purchase
(the "Change of Control Payment"). Within 30 days following any Change of
Control, the Company shall mail a notice to each Holder setting forth the
procedures governing the Change of Control Offer as required by the Indenture.

        (b) If the Company or a Restricted Subsidiary consummates any Asset
Sales, within five days of each date on which the aggregate amount of Excess
Proceeds exceeds $10 million, the Company shall

                                       A-3
<Page>

commence an Asset Sale Offer pursuant to Section 3.09 of the Indenture to all
Holders of Notes and all holders of Pari Passu Indebtedness containing
provisions similar to those set forth in the Indenture with respect to offers to
purchase or redeem with the proceeds of sales of assets to purchase the maximum
principal amount (or, if applicable, accreted value) of Notes and such 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 Liquidated Damages, thereon, if any, to the
date fixed for the closing of such offer, in accordance with the procedures set
forth in Section 3.09 of the Indenture. To the extent that the aggregate amount
of Notes (including any Additional Notes) tendered pursuant to an Asset Sale
Offer is less than the Excess Proceeds, the Company may use such difference for
any purpose not otherwise prohibited by the Indenture. If the aggregate
principal amount of Notes and such other Pari Passu Indebtedness tendered into
such Asset Sale Offer exceeds the amount of Excess Proceeds, the Trustee shall
select the Notes and such other Pari Passu Indebtedness to be purchased on a pro
rata basis based on the principal amount (or, if applicable, accreted value) of
Notes and such other Pari Passu Indebtedness tendered. Holders of Notes that are
the subject of an offer to purchase will receive an Asset Sale 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 the mailing of a notice of redemption of Notes to be redeemed or during
the period between a record date and the corresponding Interest Payment Date.

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

        11. AMENDMENT, SUPPLEMENT AND WAIVER. Subject to certain exceptions, the
Indenture, the Notes, the Indenture Guarantees, the Security Agreements and the
Intercreditor Agreements may be amended or supplemented with the consent of the
Holders of at least a majority in principal amount at maturity of the then
outstanding Notes and Additional Notes, if any, voting as a single class, and

Security Agreements may also be amended pursuant to the terms of the applicable
Intercreditor Agreement without the consent of the Holders of at least a
majority in principal amount at maturity of the Notes, and (b) any existing
default or event of default under either of the Security Agreements, and
compliance with any provision of either of the Security Agreements, may be
waived pursuant to the terms of the applicable Intercreditor Agreement without
the consent of the Holders of at least a majority in principal amount at
maturity of the Notes.

Indenture Guarantees, the Security Agreements and the Intercreditor Agreements
may be amended or supplemented to cure any ambiguity, defect or inconsistency,
to provide for uncertificated Notes in addition to or in place of certificated

related definitions) in a manner that does not materially adversely affect any
Holder, to provide for the assumption of the Company's obligations to Holders of
the Notes by a successor to the Company pursuant to Article 5 of the Indenture,

Holders of the Notes or that does not adversely affect the legal rights under
the Indenture of any such Holder, to comply with the requirements of the SEC or
in order to effect or maintain the qualification of the Indenture under the
Trust Indenture Act, to provide for the Issuance of Additional Notes in
accordance with the limitations set forth in the Indenture, or to add a

Offer in accordance with the provisions of Section 4.14 of the Indenture or the
failure of the Company to make or consummate an Asset Sale Offer in accordance
with the provisions of Section 4.10 of the Indenture; (iv) failure by the
Company or any of its Restricted Subsidiaries, for 60 days after notice to the
Company by the Trustee or the Holders of at least 25% in principal amount of the
Notes (including Additional Notes, if any) then outstanding voting as a single
class to comply with certain other agreements in the Indenture or the Notes, the
Indenture Guarantees, the Security Agreements or the Intercreditor Agreements;
(v) default under certain other agreements relating to Indebtedness of the
Company which default results in the acceleration of such Indebtedness prior to
its express maturity; (vi) certain final judgments for the payment of money that
remain undischarged for a period of 60 days; (vii) certain events of bankruptcy
or insolvency with respect to the Company or any of its Significant
Subsidiaries; (viii) the Security Agreements or the Intercreditor Agreements
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 and (ix) any Indenture
Guarantee shall be held in a judicial proceeding to be enforceable or invalid or
shall cease for any reason to be in full force and effect. 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

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.

Subsidiary Guarantor, as such, shall not have any liability for any obligations
of the Company, the Parent Guarantor or such Subsidiary Guarantor under the
Notes, the Indenture, the Indenture Guarantees or the Security Agreements or for
any claim based on, in respect of, or by reason of, such obligations or their
