SECTION 2.  DEFINITIONS.

a) Capitalized terms used herein and not otherwise defined shall have the
respective meanings assigned thereto in the Original Indenture.

b) Solely for purposes of this First Supplemental Indenture and the 6.125% Notes
and except as otherwise expressly provided or unless the context otherwise
requires, the following terms shall have the indicated meanings (such meanings
shall apply equally to both the singular and plural forms of the respective
terms):

                  "Adjusted Treasury Rate" means, with respect to any Redemption
         Date, the rate per annum equal to the semi-annual equivalent yield to
         maturity (computed as of the second business day immediately preceding
         that Redemption Date) of the Comparable Treasury Issue, assuming a
         price for the Comparable Treasury Issue (expressed as a percentage of
         its principal amount) equal to the Comparable Treasury Price for that
         Redemption Date.

                  "Comparable Treasury Issue" means the United States Treasury
         security selected by the Independent Investment Banker that would be
         utilized, at the time of selection and in accordance with customary
         financial practice, in pricing new issues of corporate debt securities
         of comparable maturity to the remaining term of the 6.125% Notes.

                  "Comparable Treasury Price" means, with respect to any
         Redemption Date, (i) the average of the bid and asked prices for the
         Comparable Treasury Issue (expressed in each case as a percentage of
         its principal amount) on the third business day preceding that
         Redemption Date, as set forth in the daily statistical release (or any
         successor release) published by the Federal Reserve Bank of New York
         and designated "Composite 3:30 p.m. Quotations for U.S. Government
         Securities" or (ii) if such release (or any successor release) is not
         published or does not contain such prices on such business day, (A) the
         average of the Reference Treasury Dealer Quotations for that Redemption
         Date, after excluding the highest and lowest of such Reference Treasury
         Dealer Quotations, or (B) if the Independent Investment Banker obtains
         fewer than four such Reference Treasury Dealer Quotations, the average
         of all such Quotations.

                  "Independent Investment Banker" means one of the Reference
         Treasury Dealers appointed by the Corporation to act as the
         "Independent Investment Banker".

                  "Outstanding" when used with respect to the 6.125% Notes has
         the same meaning assigned to "Outstanding" when used with respect to
         "Debt Securities" in the Original Indenture, except that references to
         "Debt Securities" shall be replaced by references to the "6.125%
         Notes".

                  "Reference Treasury Dealer" means each of Chase Securities
         Inc. and Salomon Smith Barney Inc. and their respective successors and
         three other nationally recognized investment banking firms that are
         Primary Treasury Dealers specified from time to time by the
         Corporation; provided, however, that if any of the foregoing shall
         cease to be a primary U.S. Government securities dealer in New York
         City (a "Primary Treasury Dealer"), the Corporation shall substitute
         therefor another nationally recognized investment banking firm that is
         a Primary Treasury Dealer.

                  "Reference Treasury Dealer Quotations" means, with respect to
         each Reference Treasury Dealer and any Redemption Date, the average, as
         determined by the Independent Investment Banker, of the bid and asked
         prices for the Comparable Treasury Issue (expressed in each case as a
         percentage of its principal amount) quoted in writing to the
         Independent Investment Banker by such Reference

                                       3
<PAGE>   4
         Treasury Dealer at 3:30 p.m., New York City time, on the third business
         day preceding that Redemption Date.

                  "Remaining Scheduled Payments" means, with respect to each
         6.125% Note to be redeemed, the remaining scheduled payments of the
         principal thereof and interest thereon that would be due after the
         related Redemption Date but for such redemption; provided, however,
         that, if that Redemption Date is not an interest payment date with
         respect to such 6.125% Note, the amount of the next succeeding
         scheduled interest payment thereon will be reduced by the amount of
         interest accrued thereon to that Redemption Date.

SECTION 3.  OPTIONAL REDEMPTION.

The 6.125% Notes will be redeemable, in whole or in part, at the option of the
Corporation at any time and from time to time at a Redemption Price equal to the
greater of (i) 100% of the principal amount of the 6.125% Notes to be redeemed
and (ii) the sum of the present values of the Remaining Scheduled Payments
discounted to the relevant Redemption Date on a semi-annual basis (assuming a
360-day year consisting of twelve 30-day months) at the Adjusted Treasury Rate
plus 25 basis points together with, in each case, accrued interest on the
principal amount of the 6.125% Notes to be redeemed to the Redemption Date.

SECTION 4.  GOVERNING LAW.

This First Supplemental Indenture and the 6.125% Notes shall be governed by, and
construed in accordance with, the laws of the State of New York, but without
giving effect to applicable principles of conflicts of law to the extent that
the application of the law of another jurisdiction would be required thereby.

                                       4

SECTION 5.  NO RECOURSE AGAINST OTHERS.

any of the 6.125% Notes, or for any claim based thereon or otherwise in respect
thereof, and no recourse under or upon any obligation, covenant or agreement of
the Corporation contained in this First Supplemental Indenture, or in any of the
6.125% Notes, or because of the creation of any indebtedness represented thereby
shall be had against any incorporator or against any past, present or future
partner, shareholder, other equityholder, officer, director, employee or
controlling person, as such, of the Corporation or of any successor Person,
either directly or through the Corporation or any successor Person, whether by
virtue of any constitution, statute or rule of law, or by the enforcement of any
assessment or penalty or otherwise, it being expressly understood that all such
liability is hereby expressly waived and released as condition of, and as a
consideration for, the execution of this First Supplemental Indenture and the
issue of the 6.125% Notes.

Section 6.  COUNTERPARTS.

This First Supplemental Indenture may be executed in any number of counterparts,
each of which shall be an original but such counterparts shall together
constitute but one and the same instrument.

         IN WITNESS WHEREOF, the parties hereto have caused this First
Supplemental Indenture to be duly executed as of the day, month and year first
above written.

                6.125% NOTES DUE FEBRUARY 15, 2006 (the "Notes")

1. Interest

                  Nortel Networks Limited, a corporation organized under the
laws of Canada (such corporation, and its successors and assigns under the
Indenture hereinafter referred to, being herein called the "Corporation"),
promises to pay interest on the principal amount of this Note at the rate per
annum shown above.

                  The Corporation will pay interest semi-annually in arrears on
each Interest Payment Date of each year commencing August 15, 2001. Interest on
the Notes will accrue from the most recent date to which interest has been paid
on the Notes or, if no interest has been paid, from the issue date, being
February 8, 2001, to but not including the subsequent Interest Payment Date. The
Corporation shall pay interest on overdue principal (plus interest on such
interest to the extent lawful), at the rate borne by the Notes 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 Corporation will pay interest to the Persons who are
registered Holders of Notes at the close of business on the Regular Record Date
preceding the Interest Payment Date even if Notes are canceled, repurchased or
redeemed after the Regular Record Date and on or before the relevant Interest
Payment Date. Holders must surrender Notes to a Paying Agent to collect
principal payments. The Corporation will pay principal and interest in U.S.
currency.

                  Payments in respect of Notes represented by a Global Security
(including principal and interest) will be made by the transfer of immediately
available funds to the accounts specified by DTC. The Corporation will make all
payments in respect of a definitive Note (including principal and interest) by
mailing a check to the address of each Person entitled thereto or by wire
transfer to an account designated by such Person, at the option of the
Corporation.

3. Paying Agent

                  Initially, Citibank, N.A. (the "Trustee"), will act as Trustee
and Paying Agent. The Corporation may appoint and change any Paying Agent
without notice to any Holder. The Corporation and any of its Affiliates may act
as Paying Agent.

4. Indenture

                  The Corporation issued the Notes under an Indenture by and
among the Corporation, Nortel Networks Capital Corporation ("NNCC") and the
Trustee, dated as of December 15, 2000, as supplemented by the First
Supplemental Indenture by and among the Corporation, NNCC and the Trustee, dated
as of February 1, 2001 (as amended or supplemented from time to time in
accordance with the terms thereof, collectively, the "Indenture"). The terms of
the Notes include those stated in the Indenture and those made part of the
Indenture by reference to the Trust Indenture Act of 1939 (15 U.S.C. Section
Section 77aaa-77bbbb) as in effect on the date

                                       8
<PAGE>   9
of the Original Indenture (the "Act"). Capitalized terms used herein and not
defined herein have the meanings ascribed thereto in the Indenture. The Notes
are subject to all such terms, and Holders are referred to the Indenture and the
Act for a statement of those terms. Each Holder by accepting a Note, agrees to
be bound by all of the terms and provisions of the Indenture, as amended from
time to time.

                  The Notes are senior unsecured obligations of the Corporation,
ranking pari passu in right of payment with each other and with all senior
unsecured indebtedness of the Corporation.

                  The Indenture imposes certain limitations on, among other
things, the ability of the Corporation and its Restricted Subsidiaries, as
applicable, to: (i) incur Funded Debt, (ii) incur Liens or (iii) amalgamate,
merge or transfer or convey all or substantially all of the Corporation's and
its Subsidiaries' assets, in each case as provided for in the Indenture.

5. Optional Redemption

                  The Notes will be redeemable, in whole or in part, at the
Corporation's option at any time and from time to time at a Redemption Price
equal to the greater of (i) 100% of the principal amount of the Notes to be
redeemed and (ii) the sum of the present values of the Remaining Scheduled
Payments discounted to the relevant Redemption Date on a semi-annual basis
(assuming a 360-day year consisting of twelve 30-day months) at the Adjusted
Treasury Rate plus 25 basis points together with, in each case, accrued
interest on the principal amount of the Notes to be redeemed to the Redemption
Date.

                  Notice of any redemption will be mailed at least 30 days but
not more than 45 days before the Redemption Date to each Holder of the Notes to
be redeemed. On and after any Redemption Date, interest will cease to accrue on
the Notes or any portion thereof called for redemption. On or before any
Redemption Date, the Corporation shall deposit with the Paying Agent (or the
Trustee) money sufficient to pay the Redemption Price of and accrued interest on
the Notes to be redeemed on that Redemption Date. If less than all the Notes are
to be redeemed, the Notes to be redeemed shall be selected by the Trustee by
such method as the Trustee shall deem fair and appropriate. The Redemption Price
shall be calculated by the Independent Investment Banker and the Corporation,
the Trustee and the Paying Agent shall be entitled to rely on such calculation.

6. Denominations; Transfer; Exchange

                  The Notes are issued in fully registered book-entry form
without coupons, and only in denominations of principal amount of $1,000 and any
integral multiple thereof. A Holder may transfer or exchange Notes in accordance
with the Indenture. The Corporation may require a Holder, among other things, to
furnish appropriate endorsements or transfer documents and to pay any taxes and
fees required by law or permitted by the Indenture. The Corporation need not
register the transfer of or exchange (i) any Notes selected for redemption
(except, in the case of a Note to be redeemed in part, the portion of the Note
not to be redeemed) for a period beginning 15 days before the mailing of a
notice of Notes to be redeemed and ending on the date of such mailing or (ii)
any Notes so selected for redemption in whole or in part, except the unredeemed
portion of any Note being redeemed in part.

7. Persons Deemed Owners

                  The registered holder of this Note may be treated as the owner
of it for all purposes.

8. Unclaimed Money

                  If money for the payment of principal, premium, if any, or
interest remains unclaimed for two years, the Trustee or Paying Agent shall pay
the money back to the Corporation at its request unless an abandoned property
law designates another Person. After any such payment, Holders entitled to the
money must look only to the Corporation and not to the Trustee for payment.

9. Amendment, Waiver

                  Subject to certain exceptions set forth in the Indenture, (i)
the Indenture, as it pertains to the Notes, or the Notes may be amended with the
written consent of the Holders of at least a majority in principal amount of the
then Outstanding Notes and (ii) any default (other than with respect to
nonpayment or in respect of a provision in the Indenture that cannot be modified
or amended under Article Nine without the written consent of each Holder of the
Notes affected) or noncompliance with any provision may be waived with the
written consent of the Holders of a majority in principal amount of the then
Outstanding Notes.

facsimile signature.

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

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

         At any time and from time to time after the execution and delivery of
this Indenture, the Issuers may deliver Notes executed by the Issuers to the
Trustee for authentication; and the Trustee shall authenticate and deliver (i)
Initial Notes for original issue in the aggregate principal amount of
$900,000,000, (ii) Additional Notes from time to time for original issue in
aggregate principal amount specified by the Issuers and (iii) Exchange Notes
from time to time for issue in exchange for a like principal amount of Initial
Notes or Initial Additional Notes, in each case specified in clauses (i) through
(iii) above, upon a written order of the Issuers signed by an Officer of each of
the Issuers (an "Authentication Order"). Such Authentication Order shall specify
the amount of Notes to be authenticated and the date on which the Notes are to
be authenticated, whether such notes are to be Initial Notes, Additional Notes
or Exchange Notes and whether the Notes are to be issued as one or more Global
Notes and such other information as the Issuers may include or the Trustee may
reasonably request. The aggregate principal amount of Notes which may be
authenticated and delivered under this Indenture is unlimited.

         On the Issue Date, the Issuers will issue $900,000,000 aggregate
principal amount of Initial Notes. Initial Notes and any Initial Additional
Notes offered and sold in reliance on the exemption from registration under the
Securities Act provided by Section 4(2) thereunder or Rule 144A shall be issued
as one or more Rule 144A Global Notes. Initial Notes and any Initial Additional
Notes offered and sold in offshore transactions in reliance on Regulation S
shall be issued as one or more Regulation S Global Notes.

         The Trustee may appoint an authenticating agent acceptable to the
Issuers 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 Issuers.

Section 2.03.     Registrar and Paying Agent.

         The Issuers shall maintain an office or agency where Notes may be
presented for registration of transfer or for exchange ("Registrar") and an
office or agency where Notes may be presented for payment ("Paying Agent"). The
Registrar shall keep a register of the Notes and of their transfer and exchange.
The Issuers 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 Issuers may change any
Paying Agent or Registrar without notice to any Holder. The Issuers shall notify
the Trustee in writing of the name and address of any Agent not a party to this
Indenture. If the Issuers fail to appoint or maintain another entity as
Registrar or Paying Agent, the Trustee shall act as such. The Issuers or any of
their Subsidiaries may act as Paying Agent or Registrar.

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

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

Section 2.04.     Paying Agent to Hold Money in Trust.

         The Issuers shall require each Paying Agent other than the Trustee to
agree in writing that the Paying Agent shall hold in trust for the benefit of
Holders or the Trustee all money held by the Paying Agent for the payment of
principal, premium, if any, or interest on the Notes, and shall notify the
Trustee of any default by the Issuers 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 Issuers 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 Issuers or a Subsidiary) shall have no further
liability for the money. If the Issuers 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 Issuers, 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 ss. 312(a). If the Trustee is
not the Registrar, the Issuers 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

                                       29
<PAGE>   30
such date as the Trustee may reasonably require of the names and addresses of
the Holders of Notes and the Issuers shall otherwise comply with TIA ss. 312(a).

Section 2.06.     Transfer and Exchange.

         (a) Transfer and Exchange of Global Notes. A Global Note may not be
transferred as a whole except by the Depositary to a nominee of the Depositary,
by a nominee of the Depositary to the Depositary or to another nominee of the
Depositary, or by the Depositary or any such nominee to a successor Depositary
or a nominee of such successor Depositary. All Global Notes shall be exchanged
by the Company for Definitive Notes if:

                  (i) the Issuers deliver to the Trustee notice from the
         Depositary that it is unwilling or unable to continue to act as
         Depositary or that it is no longer a clearing agency registered under
         the Exchange Act and, in either case, a successor Depositary is not
         appointed by the Issuers within 120 days after the date of such notice
         from the Depositary; or

                  (ii) the Issuers in their sole discretion determine that the
         Global Notes (in whole but not in part) should be exchanged for
         Definitive Notes and deliver a written notice to such effect to the
         Trustee; or

                  (iii) there shall have occurred and be continuing a Default or
         Event of Default with respect to the Notes.

         Upon the occurrence of any of the preceding events in (i), (ii) or
(iii) above, Definitive Notes shall be issued in such names as the Depositary
shall instruct the Trustee. Global Notes also may be exchanged or replaced, in
whole or in part, as provided in Sections 2.07 and 2.10. Every Note
authenticated and delivered in exchange for, or in lieu of, a Global Note or any
portion thereof, pursuant to this Section 2.06 or Section 2.07 or 2.10, shall be
authenticated and delivered in the form of, and shall be, a Global Note. A
Global Note may not be exchanged for another Note other than as provided in this
Section 2.06(a); however, beneficial interests in a Global Note may be
transferred and exchanged as provided in Section 2.06(b), (c) or (f).

         (b) Transfer and Exchange of Beneficial Interests in the Global Notes.
The transfer and exchange of beneficial interests in the Global Notes shall be
effected through the Depositary, in accordance with the provisions of this
Indenture and the Applicable Procedures. Beneficial interests in the Restricted
Global Notes shall be subject to restrictions on transfer comparable to those
set forth herein to the extent required by the Securities Act. Prior to the
expiration of the 40-day distribution compliance period set forth in Regulation
S, beneficial interests in any Regulation S Global Notes may be held only
through Euroclear or Clearstream unless transferred in accordance with

                                       30
<PAGE>   31
Section 2.06(b)(iii)(A). Transfers of beneficial interests in the Global Notes
also shall require compliance with either subparagraph (i) or (ii) below, as
applicable, as well as one or more of the other following subparagraphs, as
applicable:

                  (i) Transfer of Beneficial Interests in the Same Global Note.
         Beneficial interests in any Restricted Global Note may be transferred
         to Persons who take delivery thereof in the form of a beneficial
         interest in the same Restricted Global Note in accordance with the
         transfer restrictions set forth in the Private Placement Legend.
         Beneficial interests in any Unrestricted Global Note may be transferred
         to Persons who take delivery thereof in the form of a beneficial
         interest in an Unrestricted Global Note. No written orders or
         instructions shall be required to be delivered to the Registrar to
         effect the transfers described in this Section 2.06(b)(i).

                  (ii) All Other Transfers and Exchanges of Beneficial Interests
         in Global Notes. In connection with all transfers and exchanges of
         beneficial interests that are not subject to Section 2.06(b)(i) above,
         the transferor of such beneficial interest must deliver to the
         Registrar either:

                           (A)(1) a written order from a Participant or an
                  Indirect Participant given to the Depositary in accordance
                  with the Applicable Procedures directing the Depositary to
                  credit or cause to be credited a beneficial interest in
                  another Global Note in an amount equal to the beneficial
                  interest to be transferred or exchanged; and

                           (A)(2) instructions given in accordance with the

                  Indirect Participant given to the Depositary in accordance
                  with the Applicable Procedures directing the Depositary to
                  cause to be issued a Definitive Note in an amount equal to the
                  beneficial interest to be transferred or exchanged; and

                           (B)(2) instructions given by the Depositary to the

         otherwise applicable under the Securities Act, the Trustee shall adjust

         2.06(h).

                  (iii)Transfer of Beneficial Interests to Another Restricted
         Global Note. A beneficial interest in any Restricted Global Note may be
         transferred to a Person who takes delivery thereof in the form of a
         beneficial interest in another Restricted Global Note if the transfer
         complies with the requirements of Section 2.06(b)(ii) above and the
         Registrar receives the following:

                           (A) if the transferee will take delivery in the form

         Global Note. A beneficial interest in any Restricted Global Note may be

         Unrestricted Global Note or transferred to a Person who takes delivery
         thereof in the form of a beneficial interest in an Unrestricted Global
         Note if the exchange or transfer complies with the requirements of
         Section 2.06(b)(ii) above and:

                           (A) such exchange or transfer is effected pursuant to

<PAGE>   33
                                    (1) if the holder of such beneficial
                           interest in a Restricted Global Note proposes to
                           exchange such beneficial interest for a beneficial

                  restrictions on transfer contained herein and in the Private
                  Placement Legend are no longer required in order to maintain
                  compliance with the Securities Act.

         Definitive Note issued pursuant to subparagraphs (b)(iv), (c)(ii),
         (c)(iii), (d)(ii), (d)(iii), (e)(ii), (e)(iii) or (f) to this Section

         BE TRANSFERRED TO A SUCCESSOR DEPOSITARY WITH THE PRIOR WRITTEN CONSENT
         OF THE ISSUERS."

         (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. 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) To permit registrations of transfers and exchanges, the
         Issuers shall execute and the Trustee shall authenticate Global Notes

         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 Issuers 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, 3.03, 4.11, 4.16 and
         9.05).

                           (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 Issuers,
         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 Issuers shall not be required 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 Issuers 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 Issuers 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.

Section 2.07. Replacement Notes.

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

         Every replacement Note is an additional legally binding obligation of
the Issuers 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 of this Indenture, and those described
in this Section as not outstanding. Except as set forth in Section 2.09, a Note
does not cease to be outstanding because either of the Issuers or an Affiliate
of the Issuers holds the Note.

         If a Note is replaced pursuant to Section 2.07, it ceases to be
outstanding unless the Trustee receives proof satisfactory to it that the
replaced Note is held by a bona fide purchaser.

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

         If the Paying Agent (other than an Issuer, 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 an
Issuer, or by any Person directly or indirectly controlling or controlled by or
under direct or indirect common control with an Issuer, 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 knows are so owned shall be
so disregarded.

Section 2.10. Temporary Notes.

         Until certificates representing Notes are ready for delivery, the
Issuers 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 Issuers
considers appropriate for temporary Notes and as shall be reasonably acceptable
to the Trustee. Without unreasonable delay, the Issuers 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.

                                       44

Section 2.11. Cancellation.

         The Issuers 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
such canceled Notes in its customary manner. The Issuers may not issue new Notes
to replace Notes that they have paid or that have been delivered to the Trustee
for cancellation.

Section 2.12. Defaulted Interest.

         If the Issuers default in a payment of interest on the Notes, they
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. The Issuers 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 Issuers 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
Issuers (or, upon the written request of the Issuers, the Trustee in the name
and at the expense of the Issuers) 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.

Section 3.03. Offer to Purchase by Application of Excess Proceeds.

         In the event that the Issuers shall be required to commence an offer to
all Holders to purchase Notes pursuant to Section 4.11 (an "Asset Sale Offer"),
they shall follow the procedures specified below.

         The Asset Sale Offer shall remain open for a period of 20 Business Days
following its commencement and no longer, except to the extent that a longer
period is required by applicable law (the "Offer Period"). No later than five
Business Days after the termination of the Offer Period (the "Purchase Date"),
the Issuers shall purchase the principal amount of Notes required to be
purchased pursuant to Section 4.11 (the "Offer Amount") or, if less than the
Offer Amount has been tendered, all Notes tendered in response to the Asset Sale
Offer. Payment for any Notes so purchased shall be made in the same manner as
interest payments are made. Unless the Issuers default in making such payment,
any Note accepted for payment pursuant to the Asset Sale Offer shall cease to
accrue interest after the Purchase Date.

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

         Upon the commencement of an Asset Sale Offer the Issuers 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
shall govern the terms of the Asset Sale Offer, shall state:

         (a) that the Asset Sale Offer is being made pursuant to this Section
3.03 and Section 4.11 and the length of time the Asset Sale Offer shall remain
open;

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

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

         (d) that, unless the Issuers default in making such payment, any Note
accepted for payment pursuant to the Asset Sale Offer shall cease to accrue
interest after the Purchase Date;

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

                                       46
<PAGE>   47
         (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 Issuers, a depositary, if appointed by
the Issuers, 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
Issuers, the depositary or the Paying Agent, as the case may be, receives, not
later than the expiration of the Offer Period, a telegram, telex, facsimile
transmission or letter setting forth the name of the Holder, the principal
amount of the Note the Holder delivered for purchase and a statement that such
Holder is withdrawing his election to have such Note purchased;

         (h) that, if the aggregate principal amount of Notes surrendered by
Holders exceeds the Offer Amount, the Issuers shall select the Notes to be
purchased on a pro rata basis (with such adjustments as may be deemed
appropriate by the Issuers 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).

         On or before the Purchase Date, the Issuers shall, to the extent
lawful, accept for payment, on a pro rata basis to the extent necessary, the
Offer Amount of Notes or portions thereof tendered pursuant to the Asset Sale
Offer 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 Issuers in accordance
with the terms of this Section 3.03. The Issuers, 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 Issuers for purchase, and the Issuers shall promptly issue a new Note, and
the Trustee, upon written request from the Issuers, 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 Issuers to the Holder thereof. The Issuers
shall publicly announce the results of the Asset Sale Offer on the Purchase
Date.

Section 4.01. Payment of Notes.

         The Issuers shall pay or cause to be paid the principal, premium, if
any, and interest on the Notes on the dates and in the manner provided in the
Notes. Principal, premium, if any, and interest shall be considered paid on the
date due if the Paying Agent, if other than the Issuers or a Subsidiary thereof,
holds as of 10:00 a.m. New York City time on the due date money deposited by the
Issuers in immediately available funds and designated for and sufficient to pay
all principal, premium, if any, and interest then due. The Issuers shall pay all

upon the Issuers in respect of the Notes and this Indenture may be served. The
Issuers shall give prompt written notice to the Trustee of the location, and any
change in the location, of such office or agency. If at any time the Issuers
shall fail to maintain any such required office or agency or shall fail to
furnish the Trustee with the address thereof, such presentations, surrenders,
notices and demands may be made or served at the Corporate Trust Office of the
Trustee.

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

violated any provisions of Article 4 or Article 5 or, if any such violation has
occurred, specifying the nature and period of existence thereof, it being

         (3) such Restricted Payment, together with the aggregate amount of all
other Restricted Payments made by the Company and each of its Restricted
Subsidiaries after March 17, 1999 (excluding Restricted Payments permitted by
clauses (2), (3), (4), (5), (6), (7) and (8) of the next succeeding paragraph),
shall not exceed, at the date of determination, the sum of:

                  (a) an amount equal to 100% of the Consolidated EBITDA of the
         Company since March 17, 1999 to the end of the Company's most recently
         ended full fiscal quarter for which internal financial statements are
         available, taken as a single accounting period, less the product of 1.2
         times the Consolidated Interest Expense of the Company since March 17,
         1999 to the end of the Company's most recently ended full fiscal
         quarter for which internal financial statements are available, taken as
         a single accounting period, plus

                  (b) an amount equal to 100% of Capital Stock Sale Proceeds
         less any such Capital Stock Sale Proceeds used in connection with (i)
         an Investment made pursuant to clause (5) of the definition of
         "Permitted Investments" or (ii) the incurrence of Indebtedness pursuant
         to clause (10) of Section 4.10, plus

                  (c) $100 million.

         So long as no Default has occurred and is continuing or would be caused
thereby, the preceding provisions shall not prohibit:

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

         (2) the redemption, repurchase, retirement, defeasance or other
acquisition of any subordinated Indebtedness of the Company in exchange for, or
out of the net proceeds of, the substantially concurrent sale (other than to a
Subsidiary of the Company) of Equity Interests of the Company (other than
Disqualified Stock); provided that the amount of any such net cash proceeds that
are utilized for any such redemption, repurchase, retirement, defeasance or
other acquisition shall be excluded from clause (3) (b) of the preceding
paragraph;

                                       52
<PAGE>   53
         (3) the defeasance, redemption, repurchase or other acquisition of
subordinated Indebtedness of the Company or any of its Restricted Subsidiaries
with the net cash proceeds from an incurrence of Permitted Refinancing
Indebtedness;

         (4) regardless of whether a Default then exists, the payment of any
dividend or distribution to the extent necessary to permit direct or indirect
beneficial owners of shares of Capital Stock of the Company to pay federal,
state or local income tax liabilities that would arise solely from income of the
Company or any of its Restricted Subsidiaries, as the case may be, for the
relevant taxable period and attributable to them solely as a result of the
Company (and any intermediate entity through which the holder owns such shares)
or any of its Restricted Subsidiaries being a limited liability company,
partnership or similar entity for federal income tax purposes;

         (5) regardless of whether a Default then exists, the payment of any
dividend by a Restricted Subsidiary of the Company to the holders of its common
Equity Interests on a pro rata basis;

         (6) the payment of any dividend on the Helicon Preferred Stock or the
redemption, repurchase, retirement or other acquisition of the Helicon Preferred
Stock in an amount not in excess of its aggregate liquidation value;

         (7) the repurchase, redemption or other acquisition or retirement for
value, or the payment of any dividend or distribution to the extent necessary to
permit the repurchase, redemption or other acquisition or retirement for value,
of any Equity Interests of the Company or a Parent held by any member of the
Company's or such Parent's management pursuant to any management equity
subscription agreement or membership or stock option agreement in effect as of
the Issue Date; provided that the aggregate price paid for all such repurchased,
redeemed, acquired or retired Equity Interests shall not exceed $10 million in
any fiscal year of the Company; and

         (8) payment of fees in connection with any acquisition, merger or
similar transaction in an amount that does not exceed an amount equal to 1.25%
of the transaction value of such acquisition, merger or similar transaction.

         The amount of all Restricted Payments (other than cash) shall be the
fair market value on the date of the Restricted Payment of the asset(s) or
securities proposed to be transferred or issued by the Company or any of its
Restricted Subsidiaries pursuant to the Restricted Payment. The fair market
value of any assets or securities that are required to be valued by this
covenant shall be determined by the Board of Directors of the Company, whose
resolution with respect thereto shall be delivered to the Trustee. Such Board of
Directors' determination must be based upon an opinion or appraisal issued by an
accounting, appraisal or investment banking firm of national standing if the
fair market value exceeds $100 million. Not later than the date of making any
Restricted

                                       53
<PAGE>   54
Payment, the Company shall deliver to the Trustee an Officers' Certificate
stating that such Restricted Payment is permitted and setting forth the basis
upon which the calculations required by this Section 4.07 were computed,
together with a copy of any fairness opinion or appraisal required by this
Indenture.

Section 4.08. Investments.

         The Company shall not, and shall not permit any of its Restricted
Subsidiaries to, directly or indirectly:

         (1) make any Restricted Investment; or

         (2) allow any Restricted Subsidiary of the Company to become an
Unrestricted Subsidiary,

unless, in each case:

         (1) no Default or Event of Default shall have occurred and be
continuing or would occur as a consequence thereof; and

         (2) the Company would, at the time of, and after giving effect to, such
Restricted Investment or such designation of a Restricted Subsidiary as an
Unrestricted Subsidiary, have been permitted to incur at least $1.00 of
additional Indebtedness pursuant to the Leverage Ratio test set forth in the
first paragraph of Section 4.10.

         Any designation of a Subsidiary of the Company as an Unrestricted
Subsidiary shall be evidenced to the Trustee by filing with the Trustee a
certified copy of the Board Resolution of the Company giving effect to such
designation and an Officers' Certificate certifying that such designation
complied with the preceding conditions and was permitted by this Section 4.08.
If, at any time, any Unrestricted Subsidiary would fail to meet the requirements
as an Unrestricted Subsidiary described in the definition of "Unrestricted
Subsidiary," it shall thereafter cease to be an Unrestricted Subsidiary for
purposes of this Indenture and any Indebtedness of such Subsidiary shall be
deemed to be incurred by a Restricted Subsidiary of the Company as of such date
and, if such Indebtedness is not permitted to be incurred as of such date under
Section 4.10, the Company shall be in default. The Board of Directors of the
Company may at any time designate any Unrestricted Subsidiary to be a Restricted
Subsidiary; provided that such designation shall be deemed to be an incurrence
of Indebtedness by a Restricted Subsidiary of the Company of any outstanding
Indebtedness of such Unrestricted Subsidiary and such designation shall only be
permitted if (1) such Indebtedness is permitted under Section 4.10 calculated on
a pro forma basis as if such designation had occurred at the beginning of the
Reference Period; and (2) no Default or Event of Default would be in existence
following such designation.

Section 4.09. Dividend and Other Payment Restrictions Affecting Subsidiaries.

         The Company shall not, directly or indirectly, create or permit to
exist or become effective any encumbrance or restriction on the ability of any
Restricted Subsidiary of the Company to:

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

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

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

However, the preceding restrictions shall not apply to encumbrances or
restrictions existing under or by reason of:

         (1) Existing Indebtedness as in effect on the Issue Date (including,
without limitation, the Credit Facilities) and any amendments, modifications,
restatements, renewals, increases, supplements, refundings, replacements or
refinancings thereof, provided that such amendments, modifications,
restatements, renewals, increases, supplements, refundings, replacements or
refinancings are no more restrictive, taken as a whole, with respect to such
dividend and other payment restrictions than those contained in such Existing
Indebtedness, as in effect on the Issue Date;

         (2) this Indenture, the Notes and the Other Notes;

         (3) applicable law;

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

         (5) customary non-assignment provisions in leases entered into in the
ordinary course of business and consistent with past practices;

                                       55
<PAGE>   56
         (6) purchase money obligations for property acquired in the ordinary
course of business that impose restrictions on the property so acquired of the
nature described in clause (3) of the preceding paragraph;

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

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

         (9) Liens securing Indebtedness otherwise permitted to be incurred
under Section 4.14 that limit the right of the Company or any of its Restricted
Subsidiaries to dispose of the assets subject to such Lien;

         (10) provisions with respect to the disposition or distribution of
assets or property in joint venture agreements and other similar agreements
entered into in the ordinary course of business;

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

         (12) restrictions contained in the terms of Indebtedness permitted to
be incurred under Section 4.10; provided that such restrictions are no more
restrictive than the terms contained in the Credit Facilities as in effect on
the Issue Date; and

         (13) restrictions that are not materially more restrictive than
customary provisions in comparable financings and the management of the Company
determines that such restrictions will not materially impair the Company's
ability to make payments as required under the Notes.

Section 4.10. 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 and shall not
permit any of its Restricted Subsidiaries to issue any shares of Preferred Stock
unless the Leverage Ratio would have been not greater than 8.75 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

                                       56
<PAGE>   57
Disqualified Stock had been issued, as the case may be, at the beginning of the
most recently ended fiscal quarter.

         So long as no Default shall have occurred and be continuing or would be
caused thereby, the first paragraph of this covenant shall not prohibit the
incurrence of any of the following items of Indebtedness (collectively,
"Permitted Debt"):

         (1) the incurrence by the Company and its Restricted Subsidiaries of
Indebtedness under the Credit Facilities; provided that the aggregate principal
amount of all Indebtedness of the Company and its Restricted Subsidiaries
outstanding under all Credit Facilities after giving effect to such incurrence
does not exceed an amount equal to $3.5 billion less the aggregate amount of all
Net Proceeds of Asset Sales applied by the Company or any of its Subsidiaries in
the case of an Asset Sale since March 17, 1999 to repay Indebtedness under a
Credit Facility pursuant to Section 4.11;

         (2) the incurrence by the Company and its Restricted Subsidiaries of
Existing Indebtedness (other than the Credit Facilities);

         (3) the incurrence on the Issue Date by the Company and its Restricted
Subsidiaries of Indebtedness represented by the Notes (other than any Additional
Notes) and the Other Notes;

         (4) the incurrence by the Company or any of its Restricted Subsidiaries
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 construction or improvement
(including, without limitation, the cost of design, development, construction,
acquisition, transportation, installation, improvement, and migration) of
Productive Assets of the Company or any of its Restricted Subsidiaries, in an
aggregate principal amount not to exceed $75 million at any time outstanding;

         (5) the incurrence by the Company or any of its Restricted Subsidiaries
of Permitted Refinancing Indebtedness in exchange for, or the net proceeds of
which are used to refund, refinance or replace, in whole or in part,
Indebtedness (other than intercompany Indebtedness) that was permitted by this
Indenture to be incurred under the first paragraph of this covenant or clauses
(2) or (3) of this paragraph;

         (6) the incurrence by the Company or any of its Restricted Subsidiaries
of intercompany Indebtedness between or among the Company and any of its Wholly
Owned Restricted Subsidiaries; provided 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

                                       57
<PAGE>   58
                  (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 Wholly Owned Restricted Subsidiary thereof
         and (ii) any sale or other transfer of any such Indebtedness to a
         Person that is not either the Company or a Wholly Owned Restricted
         Subsidiary thereof, shall be deemed, in each case, to constitute an
         incurrence of such Indebtedness by the Company or any of its Restricted
         Subsidiaries that was not permitted by this clause (6);

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

         (8) the guarantee by the Company of Indebtedness of a Restricted
Subsidiary of the Company that was permitted to be incurred by another provision
of this Section 4.10;

         (9) the incurrence by the Company or any of its Restricted Subsidiaries
of additional Indebtedness in an aggregate principal amount at any time
outstanding not to exceed $300 million;

         (10) the incurrence by the Company or any of its Restricted
Subsidiaries of additional Indebtedness in an aggregate principal amount at any
time outstanding not to exceed 200% of the net cash proceeds received by the
Company from the sale of its Equity Interests (other than Disqualified Stock)
after March 17, 1999 to the extent such net cash proceeds have not been applied
to make Restricted Payments or to effect other transactions pursuant to Section
4.07 or to make Permitted Investments pursuant to clause (5) of the definition
thereof; and

         (11) the accretion or amortization of original issue discount and the
write up of Indebtedness in accordance with purchase accounting.

         For purposes of determining compliance with this Section 4.10, in the
event that an item of proposed Indebtedness meets the criteria of more than one
of the categories of Permitted Debt described in clauses (1) through (11) above,
or is entitled to be incurred pursuant to the first paragraph of this covenant,
the Company shall be permitted to classify and from time to time to reclassify
such item of Indebtedness in any manner that complies with this covenant. For
avoidance of doubt, Indebtedness incurred pursuant to a single agreement,
instrument, program, facility or line of credit may be classified as
Indebtedness arising in part under one of the clauses listed above, and in part
under any one or more of the clauses listed above, to the extent that such
Indebtedness satisfies the criteria for such clauses.

                                       58
<PAGE>   59
         Notwithstanding the foregoing, in no event shall any Restricted
Subsidiary of the Company consummate a Subordinated Debt Financing or a
Preferred Stock Financing. A "Subordinated Debt Financing" or a "Preferred Stock
Financing", as the case may be, with respect to any Restricted Subsidiary of the
Company shall mean a public offering or private placement (whether pursuant to
Rule 144A under the Securities Act or otherwise) of Subordinated Notes or
Preferred Stock (whether or not such Preferred Stock constitutes Disqualified
Stock), as the case may be, of such Restricted Subsidiary to one or more
purchasers (other than to one or more Affiliates of the Company). "Subordinated
Notes" with respect to any Restricted Subsidiary of the Company shall mean
Indebtedness of such Restricted Subsidiary that is contractually subordinated in
right of payment to any other Indebtedness of such Restricted Subsidiary
(including, without limitation, Indebtedness under the Credit Facilities). The
foregoing limitation shall not apply to (i) any Indebtedness or Preferred Stock
of any Person existing at the time such Person is merged with or into or became
a Subsidiary of the Company; provided that such Indebtedness or Preferred Stock
was not incurred or issued in connection with, or in contemplation of, such
Person merging with or into, or becoming a Subsidiary of, the Company and (ii)
any Indebtedness or Preferred Stock of a Restricted Subsidiary issued in
connection with, and as part of the consideration for, an acquisition, whether
by stock purchase, asset sale, merger or otherwise, in each case involving such
Restricted Subsidiary, which Indebtedness or Preferred Stock is issued to the
seller or sellers of such stock or assets; provided that such Restricted
Subsidiary is not obligated to register such Indebtedness or Preferred Stock
under the Securities Act or obligated to provide information pursuant to Rule
144A under the Securities Act.

Section 4.11. Limitation on Asset Sales.

         The Company shall not, and shall not permit any of its Restricted
Subsidiaries to, consummate an Asset Sale unless:

         (1) the Company or a Restricted Subsidiary of the Company, 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;

         (2) such fair market value is determined by the Company's Board of
Directors and evidenced by a resolution of such Board of Directors set forth in
an Officers' Certificate delivered to the Trustee; and

         (3) at least 75% of the consideration therefor received by the Company
or such Restricted Subsidiary is in the form of cash, Cash Equivalents or
readily marketable securities.

                                       59
<PAGE>   60
         For purposes of this Section 4.11, 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) of the Company or
         any Restricted Subsidiary of the Company (other than contingent
         liabilities and liabilities that are by their terms subordinated to the
         Notes) that are assumed by the transferee of any such assets pursuant
         to a customary novation agreement that releases the Company or such
         Restricted Subsidiary from further liability;

                  (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, Cash
         Equivalents or readily marketable securities within 60 days after
         receipt thereof (to the extent of the cash, Cash Equivalents or readily
         marketable securities received in that conversion); and

                  (c) Productive Assets.

         Within 365 days after the receipt of any Net Proceeds from an Asset
Sale, the Company or a Restricted Subsidiary of the Company, as the case may be,
may apply such Net Proceeds at its option:

         (1) to repay debt under the Credit Facilities or any other Indebtedness
of the Restricted Subsidiaries of the Company (other than Indebtedness
represented by a guarantee of a Restricted Subsidiary of the Company); or

         (2) to invest in Productive Assets; provided that any Net Proceeds
which the Company or a Restricted Subsidiary of the Company, as the case may be,
has committed to invest in Productive Assets within 365 days of the applicable
Asset Sale may be invested in Productive Assets within two years of such Asset
Sale.

         The amount of any Net Proceeds received by the Company or a Restricted
Subsidiary of the Company from Asset Sales that are not applied or invested as
provided in the preceding paragraph shall constitute "Excess Proceeds." When the
aggregate amount of Excess Proceeds exceeds $25 million, the Issuers shall make
an Asset Sale Offer to all Holders of Notes and all holders of other
Indebtedness that is pari passu with the Notes containing provisions requiring
offers to purchase or redeem with the proceeds of sales of assets to purchase
the maximum principal amount of Notes and such other pari passu Indebtedness
that may be purchased out of the Excess Proceeds (which amount includes the
entire amount of the Net Proceeds). The offer price in any Asset Sale Offer
shall be payable in cash and equal to 100% of principal amount plus accrued and
unpaid interest, if any, to the date of purchase. If any Excess Proceeds remain
after consummation of an Asset Sale Offer, the Company or a Restricted
Subsidiary of the

                                       60
<PAGE>   61
Company may use such Excess Proceeds for any purpose not otherwise prohibited by
this 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. Upon completion of each Asset
Sale Offer, the amount of Excess Proceeds shall be reset at zero.

         In the event that the Issuers shall be required to commence an offer to
Holders to purchase Notes pursuant to this Section 4.11, they shall follow the
procedures specified in Section 3.03.

Section 4.12. Sale and Leaseback Transactions.

         The Company shall not, and shall not permit any of its Restricted
Subsidiaries to, enter into any sale and leaseback transaction; provided that
the Company may enter into a sale and leaseback transaction if:

         (1) the Company could have (a) incurred Indebtedness in an amount equal
to the Attributable Debt relating to such sale and leaseback transaction under
the Leverage Ratio test in the first paragraph of Section 4.10 and (b) incurred
a Lien to secure such Indebtedness pursuant to Section 4.14; and

         (2) the transfer of assets in that sale and leaseback transaction is
permitted by, and the Company applies the proceeds of such transaction in
compliance with, Section 4.11.

         The foregoing restrictions shall not apply to a sale and leaseback
transaction if the lease is for a period, including renewal rights, of not in
excess of three years.

Section 4.13. 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:

         (1) 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

         (2) the Company delivers to the Trustee:

                                       61
<PAGE>   62
                  (a) with respect to any Affiliate Transaction or series of
         related Affiliate Transactions involving aggregate consideration in
         excess of $15 million, a resolution of the Board of Directors of the
         Company set forth in an Officers' Certificate certifying that such
         Affiliate Transaction complies with this Section 4.13 and that such
         Affiliate Transaction has been approved by a majority of the members of
         such Board of Directors; and

                  (b) with respect to any Affiliate Transaction or series of
         related Affiliate Transactions involving aggregate consideration in
         excess of $50 million, an opinion as to the fairness to the Holders of
         such Affiliate Transaction from a financial point of view issued by an
         accounting, appraisal or investment banking firm of national standing.

         The following items shall not be deemed to be Affiliate Transactions
and, therefore, shall not be subject to the provisions of the prior paragraph:

         (1) any existing employment agreement entered into by the Company or
any of its Subsidiaries and any employment agreement entered into by the Company
or any of its Restricted Subsidiaries in the ordinary course of business and
consistent with the past practice of the Company or such Restricted Subsidiary;

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

         (3) payment of reasonable directors fees to Persons who are not
otherwise Affiliates of the Company and customary indemnification and insurance
arrangements in favor of directors, regardless of affiliation with the Company
or any of its Restricted Subsidiaries;

         (4) payment of management fees pursuant to management agreements either
(A) existing on the Issue Date or (B) entered into after the Issue Date, to the
extent that such management agreements provide for percentage fees no higher
than the percentage fees existing under the management agreements existing on
the Issue Date;

         (5) Restricted Payments that are permitted by Section 4.07 and
Restricted Investments that are permitted by Section 4.08; and

         (6) Permitted Investments.

Section 4.14. Liens.

         The Company shall not, directly or indirectly, create, incur, assume or
suffer to exist any Lien of any kind securing Indebtedness, Attributable Debt or

Section 4.15. Existence.

         Subject to Article 5, the Company shall do or cause to be done all
things necessary to preserve and keep in full force and effect (i) its limited
liability company 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 or any
such Subsidiary and (ii) the rights (charter and statutory), licenses and
franchises of the Company and its Subsidiaries; provided, however, that the
Company shall not be required to preserve any such right, license or franchise,
or the corporate, partnership or other existence of any of its Subsidiaries
(other than Charter Capital), if the Board of Directors of the Company shall
determine that the preservation thereof is no longer desirable in the conduct of
the business of the Company and its Subsidiaries, taken as a whole, and that the
loss thereof is not adverse in any material respect to the Holders of the Notes.

Section 4.16. Repurchase at the Option of Holders upon a Change of Control.

         If a Change of Control occurs, each Holder of Notes shall have the
right to require the Issuers to repurchase all or any part (equal to $1,000 or
an integral multiple thereof) of that Holder's Notes pursuant to a Change of
Control Offer. In the Change of Control Offer, the Issuers shall offer (a
"Change of Control Offer") a payment (the "Change of Control Payment") in cash
equal to 101% of the aggregate principal amount of Notes repurchased plus
accrued and unpaid interest thereon, if any, to the date of purchase.

         Within ten days following any Change of Control, the Issuers shall mail
a notice to each Holder (with a copy to the Trustee) describing the transaction
or transactions that constitute the Change of Control and stating:

         (a) the purchase price and the purchase date, which shall not exceed 30
Business Days from the date such notice is mailed (the "Change of Control
Payment Date");

         (b) that any Note not tendered shall continue to accrue interest;

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

         (d) that Holders electing to have any Notes purchased pursuant to a
Change of Control Offer shall 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;

                                       63
<PAGE>   64
         (e) that Holders shall be entitled to withdraw their election if the
Paying Agent receives, not later than the close of business on the second
Business Day preceding the Change of Control Payment Date, a telegram, telex,
facsimile transmission or letter setting forth the name of the Holder, the
principal amount of Notes delivered for purchase, and a statement that such
Holder is withdrawing his election to have the Notes purchased; and

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

         The Issuers shall comply with the requirements of Rule 14e-1 under the
Exchange Act (or any successor rules) and any other securities laws and
regulations thereunder to the extent such laws and regulations are applicable in
connection with the repurchase of the Notes as a result of a Change of Control.

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

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

         (b) 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

         (c) 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 Issuers.

         The Paying Agent shall promptly pay 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, 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.

         The provisions described above that require the Issuers to make a
Change of Control Offer following a Change of Control shall be applicable
regardless of whether or not any other provisions in this Indenture are
applicable. Except as described above with respect to a Change of Control, this
Indenture does not contain provisions that permit the Holders of the Notes to
require that the Issuers repurchase or redeem the Notes in the event of a
takeover, recapitalization or similar transaction.

                                       64
<PAGE>   65
         Notwithstanding any other provision of this Section 4.16, the Issuers
shall not be required to make a Change of Control Offer upon a Change of Control
if a third party makes the Change of Control Offer in the manner, at the times
and otherwise in compliance with the requirements set forth in this Indenture
applicable to a Change of Control Offer made by the Issuers and purchases all
Notes validly tendered and not withdrawn under such Change of Control Offer.

Section 4.17. Limitations on Issuances of Guarantees of Indebtedness.

         The Company shall not permit any of its Restricted Subsidiaries,
directly or indirectly, to Guarantee or pledge any assets to secure the payment
of any other Indebtedness of the Company except in respect of the Credit
Facilities (the "Guaranteed Indebtedness") unless (i) such Restricted Subsidiary
simultaneously executes and delivers a supplemental indenture providing for the
Guarantee (a "Subsidiary Guarantee") of the payment of the Notes by such
Restricted Subsidiary and (ii) until one year after all the Notes have been paid
in full in cash, such Restricted Subsidiary waives and will not in any manner
whatsoever claim or take the benefit or advantage of, any rights of
reimbursement, indemnity or subrogation or any other rights against the Company
or any other Restricted Subsidiary of the Company as a result of any payment by
such Restricted Subsidiary under its Subsidiary Guarantee; provided that this
paragraph shall not be applicable to any Guarantee or any Restricted Subsidiary
that existed at the time such Person became a Restricted Subsidiary and was not
incurred in connection with, or in contemplation of, such Person becoming a
Restricted Subsidiary. If the Guaranteed Indebtedness is subordinated to the
Notes, then the Guarantee of such Guaranteed Indebtedness shall be subordinated
to the Subsidiary Guarantee at least to the extent that the Guaranteed
Indebtedness is subordinated to the Notes.

Section 4.18. Payments for Consent.

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

Section 4.19. Application of Fall-Away Covenants.

         During any period of time that (a) the Notes have Investment Grade
Ratings from both Rating Agencies and (b) no Default or Event of Default has
occurred and is continuing, the Company and its Restricted Subsidiaries shall
not be subject to the provisions of Sections 4.07, 4.08, 4.09, 4.10, 4.11, 4.12,
4.13 and clause (4) of the first

                                       65
<PAGE>   66
paragraph of Section 5.01 (collectively, the "Suspended Covenants"). In the
event that the Company and its Restricted Subsidiaries are not subject to the
Suspended Covenants for any period of time as a result of the preceding sentence
and, subsequently, one or both of the Rating Agencies withdraws its ratings or
downgrades the ratings assigned to the Notes below the required Investment Grade
Ratings or a Default or Event of Default occurs and is continuing, then the
Company and its Restricted Subsidiaries shall thereafter again be subject to the
Suspended Covenants and compliance with the Suspended Covenants with respect to
the Restricted Payments made after the time of such withdrawal, downgrade,
Default or Event of Default will be calculated in accordance with the terms of
Section 4.07 as though such covenant had been in effect during the entire period
of time from the Issue Date.

                                   SUCCESSORS

Section 5.01. Merger, Consolidation, or Sale of Assets.

         Neither of the Issuers may, directly or indirectly: (1) consolidate or
merge with or into another Person (whether or not such Issuer is the surviving
corporation); or (2) sell, assign, transfer, convey or otherwise dispose of all
or substantially all of its properties or assets, in one or more related
transactions, to another Person; unless:

         (1) either: (a) such Issuer is the surviving corporation; or (b) the
Person formed by or surviving any such consolidation or merger (if other than
such Issuer) or to which such sale, assignment, transfer, conveyance or other
disposition shall have been made is a Person organized or existing under the
laws of the United States, any state thereof or the District of Columbia
(provided that if the Person formed by or surviving any such consolidation or
merger with either Issuer is a limited liability company or a Person other than
a corporation, a corporate co-issuer shall also be an obligor with respect to
the Notes);

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

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

         (4) the Company or the Person formed by or surviving any such
consolidation or merger (if other than the Company) will, on the date of such
transaction after giving pro

                                       66
<PAGE>   67
forma effect thereto and any related financing transactions as if the same had
occurred at the beginning of the applicable four-quarter period, either (a) be
permitted to incur at least $1.00 of additional Indebtedness pursuant to the
Leverage Ratio test set forth in the first paragraph of Section 4.10 or (b) have
a Leverage Ratio immediately after giving effect to such consolidation or merger
no greater than the Leverage Ratio immediately prior to such consolidation or
merger.

         In addition, the Company may not, directly or indirectly, lease all or
substantially all of its properties or assets, in one or more related
transactions, to any other Person. This Section 5.01 shall not apply to a sale,
assignment, transfer, conveyance or other disposition of assets between or among
the Company and any of its Wholly Owned Subsidiaries.

Section 5.02. Successor Corporation Substituted.

         Upon any consolidation or merger, or any sale, assignment, transfer,
lease, conveyance or other disposition of all or substantially all of the assets
of either Issuer in accordance with Section 5.01, the successor Person formed by
such consolidation or into which either Issuer is merged or to which such
transfer is made shall succeed to and (except in the case of a lease) be
substituted for, and may exercise every right and power of, such Issuer under
this Indenture with the same effect as if such successor Person had been named
therein as such Issuer, and (except in the case of a lease) such Issuer shall be
released from the obligations under the Notes and this Indenture, except with
respect to any obligations that arise from, or are related to, such transaction.

                              DEFAULTS AND REMEDIES

Section 6.01. Events of Default.

         An "Event of Default" occurs if:

         (a) the Issuers default in the payment when due of interest on the
Notes and such default continues for a period of 30 days;

         (b) the Issuers default in payment when due of the principal of or
premium, if any, on the Notes;

         (c) the Company or any of its Restricted Subsidiaries fails to comply
with any of the provisions of Sections 4.16 or 5.01;

                                       67
<PAGE>   68
         (d) the Company or any of its Restricted Subsidiaries fails to comply
with any of their other covenants or agreements in this Indenture for 30 days
after written notice thereof has been given to the Company by the Trustee or to
the Company and the Trustee by Holders of at least 25% of the aggregate
principal amount of the Notes outstanding;

         (e) the Company or any of its Restricted Subsidiaries defaults 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 (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 Issue Date, if that default:

                  (1) is caused by a failure to pay at final stated maturity the
         principal amount on such Indebtedness prior to the expiration of the
         grace period provided in such Indebtedness on the date of such default
         (a "Payment Default"); or

                  (2) results in the acceleration of such Indebtedness prior to
         its express maturity,

and, in each case, the principal amount of any such Indebtedness, together with
the principal amount of any other such Indebtedness under which there has been a
Payment Default or the maturity of which has been so accelerated, aggregates
$100 million or more;

         (f) the Company or any of its Restricted Subsidiaries fails to pay
final judgments which are non-appealable aggregating in excess of $100 million
(net of applicable insurance which has not been denied in writing by the
insurer), which judgments are not paid, discharged or stayed for a period of 60
days;

         (g) the Company or any of its Significant Subsidiaries pursuant to or
within the meaning of Bankruptcy Law:

                  (i) commences a voluntary case,

                  (ii) consents to the entry of an order for relief against it
         in an involuntary case,

                  (iii) consents to the appointment of a custodian of it or for
         all or substantially all of its property, or

                  (iv) makes a general assignment for the benefit of its
         creditors; or

         (h) a court of competent jurisdiction enters an order or decree under
any Bankruptcy Law that:

                                       68
<PAGE>   69
         (i) is for relief against the Company or any of its Significant
Subsidiaries in an involuntary case;

         (ii) appoints a custodian of the Company or any of its Significant
Subsidiaries or for all or substantially all of the property of the Company or
any of its Significant Subsidiaries; or

         (iii) orders the liquidation of the Company or any of its Significant
Subsidiaries;

and the order or decree remains unstayed and in effect for 60 consecutive days.

Section 6.02. Acceleration.

         In the case of an Event of Default arising from clause (g) or (h) of
Section 6.01 with respect to the Company, all outstanding Notes shall become due
and payable immediately without further action or notice. If any other Event of
Default occurs and is continuing, the Trustee by notice to the Issuers or the
Holders of at least 25% in principal amount of the then outstanding Notes by
notice to the Issuers and the Trustee may declare all the Notes to be due and
payable immediately. The Holders of a majority in aggregate principal amount of
the Notes then outstanding by written notice to the Trustee may on behalf of all
of the Holders rescind an acceleration and its consequences if the rescission
would not conflict with any judgment or decree and if all existing Events of
Default (except nonpayment of principal, interest or premium that has become due
solely because of the acceleration) have been cured or waived.

Section 6.03. Other Remedies.

         If an Event of Default occurs and is continuing, the Trustee may pursue
any available remedy to collect the payment of principal, premium, 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 Existing 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,

                                       69
<PAGE>   70
except a continuing Default or Event of Default in the payment of the principal
of, premium, 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.

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
prejudicial to the rights of other Holders of Notes or that may involve the
Trustee in personal liability. The Trustee may take any other action which it
deems proper that is not inconsistent with any such directive.

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.

                                       70
<PAGE>   71
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, 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.

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 Issuers for the whole amount of
principal of, premium, if any, and interest remaining unpaid on the Notes and
interest on overdue principal and, to the extent lawful, interest and such
further amount as shall be sufficient to cover the costs and expenses of
collection, including the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel.

Section 6.09. Trustee May File Proofs of Claim.

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

         Third: to the Issuers 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 pursuant to Section 6.07, or a suit by Holders of more than 10%
in principal amount of the then outstanding Notes.

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.

                                       72
<PAGE>   73
         (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 required to be furnished to the Trustee hereunder and
         conforming to the requirements of this Indenture. However, the Trustee
         shall examine the certificates and opinions to determine whether or not
         they conform to the requirements of this Indenture (but need not
         confirm or investigate the accuracy of any mathematical calculations or
         other facts stated therein).

         (c) The Trustee may not be relieved from liabilities for its own gross
negligent action, its own gross 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 grossly 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.

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

         (e) No provision of this Indenture 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, claim,
damage or expense.

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

                                       73

         (g) The Trustee shall not be bound to make any investigation into the
facts or matters stated in any resolution, certificate, statement, instrument,
opinion, report, notice, request, direction, consent, order, bond, debenture or
other paper or documents.

Section 7.02. Rights of Trustee.

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

         (b) Before the Trustee acts or refrains from acting, it may require an
Officers' Certificate or an Opinion of Counsel or both. The Trustee 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
counsel of its own selection and the written advice or opinion of such counsel
or any Opinion of Counsel shall be full and complete authorization and
protection from liability in respect of any action taken, suffered or omitted by
it hereunder in good faith and in reliance thereon.

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

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

         (e) Unless otherwise specifically provided in this Indenture, any
demand, request, direction or notice from either of the Issuers shall be
sufficient if signed by an Officer of such Issuer.

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

         (g) The Trustee shall not be charged with knowledge of any Default or
Event of Default unless either (i) a Responsible Officer of the Trustee shall
have actual knowledge of such Default or Event of Default or (ii) written notice
of such Default or Event of Default shall have been given to and received by a
Responsible Officer of the Trustee by the Issuers or any Holder.

<PAGE>   75
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 Issuers or any
Affiliate of the Issuers 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.

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 Issuers' use of the proceeds from the Notes or any money
paid to the Issuers or upon the Issuers' 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 a Responsible Officer of the Trustee, the Trustee shall mail to Holders
of Notes a notice of the Default or Event of Default within 90 days after the
Trustee acquires knowledge thereof. 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 of this Indenture, 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 ss. 313(a) (but if no event described in
TIA ss. 313(a) has occurred within the twelve months preceding the reporting
date, no report need be transmitted). The Trustee also shall comply with TIA ss.
313(b)(2). The Trustee shall also transmit by mail all reports as required by
TIA ss. 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 ss. 313(d). The
Issuers shall promptly notify the Trustee when the Notes are listed on any stock
exchange.

                                       75
<PAGE>   76
Section 7.07. Compensation and Indemnity.

         The Issuers shall pay to the Trustee from time to time reasonable
compensation for its acceptance of this Indenture and services hereunder. The
Trustee's compensation shall not be limited by any law on compensation of a
trustee of an express trust. The Issuers 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.

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

         The obligations of the Issuers this Section 7.07 shall survive
resignation or removal of the Trustee and the satisfaction and discharge of this
Indenture.

         To secure the Issuers' 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 resignation or removal of the
Trustee and 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) 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 Trustee shall comply with the provisions of TIA ss. 313(b)(2) to
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 Issuers. The Holders of a majority in
principal amount of the then outstanding Notes may remove the Trustee by so
notifying the Trustee and the Issuers in writing. The Issuers may remove the
Trustee if:

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

      (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 Issuers 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 Issuers.

      If a successor Trustee does not take office within 60 days after the
retiring Trustee resigns or is removed, the retiring Trustee, the Issuers, 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 Issuers. 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.

                                       77
<PAGE>   78
Notwithstanding replacement of the Trustee pursuant to this Section 7.08, the
Issuers' obligations under Section 7.07 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 ss. 310(a)(1), (2) and (5). The Trustee is subject to
TIA ss. 310(b).

Section 7.11.     Preferential Collection of Claims Against the Issuers.

      The Trustee is subject to TIA ss. 311(a), excluding any creditor
relationship listed in TIA ss. 311(b). A Trustee who has resigned or been
removed shall be subject to TIA ss. 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 Issuers may, at the option of their respective Boards of Directors
evidenced by a resolution set forth in an Officers' Certificate of each of the
Issuers, at any time, elect to have either Section 8.02 or 8.03 be applied to
all outstanding Notes upon compliance with the conditions set forth below in
this Article 8.

Section 8.02.     Legal Defeasance and Discharge.

      Upon the Issuers' exercise under Section 8.01 of the option applicable to
this Section 8.02, the Issuers shall, subject to the satisfaction of the
conditions set forth in

                                       78
<PAGE>   79
Section 8.04, 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 Issuers 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 and the other
Sections of this Indenture referred to in (a) and (b) below, and to have
satisfied all their other obligations under such Notes and this Indenture (and
the Trustee, on demand of and at the expense of the Issuers, 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 payments in
respect of the principal of, premium, if any, and interest on such Notes when
such payments are due from the trust referred to below;

      (b) the Issuers' obligations with respect to the Notes concerning issuing
temporary Notes, registration of Notes, mutilated, destroyed, lost or stolen
Notes and the maintenance of an office or agency for payment and money for
security payments held in trust;

      (c)   the rights, powers, trusts, duties and immunities of the
Trustee and the Issuers' obligations in connection therewith; and

      (d)   the Legal Defeasance provisions of this Indenture;

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

Section 8.03.     Covenant Defeasance.

      Upon the Issuers' exercise under Section 8.01 of the option applicable to
this Section 8.03, the Issuers shall, subject to the satisfaction of the
conditions set forth in Section 8.04, be released from their obligations under
the covenants contained in Article 5 and Sections 4.03, 4.07, 4.08, 4.09, 4.10,
4.11, 4.12, 4.13, 4.14, 4.16, 4.17 and 4.19 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 Issuers may
omit to comply with and shall have no liability in

                                       79
<PAGE>   80
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, but,
except as specified above, the remainder of this Indenture and such Notes shall
be unaffected thereby. In addition, upon the Issuers' exercise under Section
8.01 of the option applicable to this Section 8.03, subject to the satisfaction
of the conditions set forth in Section 8.04, Sections 6.01(c) through 6.01(f)
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 to the outstanding Notes:

            In order to exercise either Legal Defeasance or Covenant Defeasance:

      (1) the Company must irrevocably deposit with the Trustee, in trust, for
the benefit of the Holders of the Notes, cash in U.S. dollars, non-callable
Government Securities, or a combination thereof, in such amounts as will be
sufficient, in the opinion of a nationally recognized firm of independent public
accountants, to pay the principal of, premium, if any, and interest 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;

      (2) in the case of Legal Defeasance, the Company shall have delivered to
the Trustee an Opinion of Counsel 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 Issue Date, there has
been a change in the applicable federal income tax law, in either case to the
effect that, and based thereon such opinion of counsel shall confirm that, the
Holders of the outstanding Notes will not recognize income, gain or loss for
federal income tax purposes as a result of such Legal Defeasance and will be
subject to federal income tax on the same amounts, in the same manner and at the
same times as would have been the case if such Legal Defeasance had not
occurred;

      (3) in the case of Covenant Defeasance, the Company shall have delivered
to the Trustee an Opinion of Counsel 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;

                                       80
<PAGE>   81
      (4) no Default or Event of Default shall have occurred and be continuing
either: (a) on the date of such deposit (other than a Default or Event of
Default resulting from the borrowing of funds to be applied to such deposit); or
(b) or insofar as Events of Default from bankruptcy or insolvency events are
concerned, at any time in the period ending on the 91st day after the date of
deposit;

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

      (6) the Company must have delivered to the Trustee an opinion of counsel
to the effect that after the 91st day assuming no intervening bankruptcy, that
no Holder is an insider of either of the Issuers following the deposit and that
such deposit would not be deemed by a court of competent jurisdiction a transfer
for the benefit of either Issuer in its capacity as such, the trust funds will
not be subject to the effect of any applicable bankruptcy, insolvency,
reorganization or similar laws affecting creditors' rights generally;

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

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

      Notwithstanding the foregoing, the opinion of counsel required by clause
(2) above with respect to a Legal Defeasance need not be delivered if all Notes
not theretofore delivered to the Trustee for cancellation (i) have become due
and payable or (ii) will become due and payable on the maturity date within one
year, by their terms or under arrangements satisfactory to the Trustee for the
giving of notice of redemption by the Trustee in the name, and at the expense,
of the Issuers.

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

      Subject to Section 8.06, all money and non-callable Government Securities
(including the proceeds thereof) deposited with the Trustee (or other qualifying
trustee, collectively for purposes of this Section 8.05, the "Trustee") pursuant
to Section 8.04 in respect of the outstanding Notes 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

                                       81
<PAGE>   82
directly or through any Paying Agent (including the Issuers acting as Paying
Agent) as the Trustee may determine, to the Holders of such Notes of all sums
due and to become due thereon in respect of principal, premium, if any, and
interest, but such money need not be segregated from other funds except to the
extent required by law.

      The Issuers 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 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 8 to the contrary notwithstanding, the Trustee
shall deliver or pay to the Issuers from time to time upon the request of the
Issuers any money or non-callable Government Securities held by it as provided
in Section 8.04 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)), 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 Issuers.

      Any money deposited with the Trustee or any Paying Agent, or then held by
the Issuers, in trust for the payment of the principal of, premium, if any, or
interest on any Note and remaining unclaimed for two years after such principal,
and premium, if any, or interest has become due and payable shall be paid to the
Issuers on their request or (if then held by the Issuers) shall be discharged
from such trust; and the Holder of such Note shall thereafter look only to the
Issuers for payment thereof, and all liability of the Trustee or such Paying
Agent with respect to such trust money, and all liability of the Issuers 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 Issuers 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 shall be repaid to the Issuers.

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, 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 Issuers' obligations under

                                       82
<PAGE>   83
this Indenture and the Notes, shall be revived and reinstated as though no
deposit had occurred pursuant to Section 8.02 or 8.03 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, as the case may be; provided, however, that, if the
Issuers make any payment of principal of, premium, if any, or interest on any
Note following the reinstatement of their obligations, the Issuers 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.

                                    ARTICLE 9

                        AMENDMENT, SUPPLEMENT AND WAIVER

Section 9.01.     Without Consent of Holders of Notes.

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

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

      (b)   to provide for uncertificated Notes in addition to or in place
of certificated Notes;

      (c)   to provide for or confirm the issuance of Additional Notes;

      (d) to provide for the assumption of either Issuer's obligations to
Holders of Notes in the case of a merger or consolidation or sale of all or
substantially all of the assets of such Issuer pursuant to Article 5;

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

      (f) to comply with requirements of the SEC in order to effect or maintain
the qualification of this Indenture under the TIA or otherwise as necessary to
comply with applicable law.

      Upon the request of the Issuers accompanied by a resolution of their
respective Boards of Directors authorizing the execution of any such amended or
supplemental Indenture, and upon receipt by the Trustee of the documents
described in Section 7.02, the Trustee shall join with the Issuers in the
execution of any amended or supplemental Indenture authorized or permitted by
the terms of this Indenture and to make any further

                                       83
<PAGE>   84
appropriate agreements and stipulations that may be therein contained, but the
Trustee shall not be obligated to enter into such amended or supplemental
Indenture that affects its own rights, duties or immunities under this Indenture
or otherwise.

Section 9.02.     With Consent of Holders of Notes.

      Except as provided below in this Section 9.02, this Indenture (including
Sections 4.11 and 4.16) or the Notes may be amended or supplemented with the
consent of the Holders of at least a majority in aggregate principal amount of
the Notes then outstanding (including, without limitation, consents obtained in
connection with a purchase of, or a tender offer or exchange offer for, Notes)
and, subject to Sections 6.04 and 6.07, any existing Default or compliance with
any provision of this Indenture or the Notes may be waived with the consent of
the Holders of a majority in aggregate principal amount of the Notes then
outstanding (including, without limitation, consents obtained in connection with
a purchase of, or a tender offer or exchange offer for, Notes). Section 2.08
shall determine which Notes are considered to be "outstanding" for purposes of
this Section 9.02.

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

      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 9.02 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, the Holders of a
majority in aggregate principal amount of the Notes then outstanding may waive
compliance in a particular instance by the Issuers with any provision of this
Indenture or the Notes. However, without the consent of each Holder affected, an
amendment, supplement or waiver under this Section 9.02 may not (with respect to
any Notes held by a non-consenting Holder):

                                       84
<PAGE>   85
      (a)   reduce the principal amount of Notes whose Holders must
consent to an amendment, supplement or waiver;

      (b) reduce the principal of or change the fixed maturity of any Note or
alter the payment provisions with respect to the redemption of the Notes (other
than provisions relating to Sections 4.11 and 4.16);

      (c)   reduce the rate of or extend the time for payment of interest
on any Note;

      (d) waive a Default or Event of Default in the payment of principal of, or
premium, if any, or interest on the Notes (except a rescission of acceleration
of the Notes by the Holders of at least a majority in aggregate principal amount
of the Notes 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 premium, if any, or interest on the Notes;

      (g)   waive a redemption payment with respect to any Note (other
than a payment required by Sections 4.11 and 4.16); or

      (h)   make any change in this Section 9.02.

Section 9.03.     Compliance with Trust Indenture Act.

      Every amendment or supplement to this Indenture or the Notes 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, 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 Issuers 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 authorized
pursuant to this Article 9 if the amendment or supplement does not adversely
affect the rights, duties, liabilities or immunities of the Trustee. The Issuers
may not sign an amendment or supplemental Indenture until their respective
Boards of Directors approve it. In executing any amended or supplemental
indenture, the Trustee shall be entitled to receive and (subject to Section
7.01) shall be fully protected in relying upon, in addition to the documents
required by Section 10.04, an Officer's Certificate and an Opinion of Counsel,
in each case from each of the Issuers, stating that the execution of such
amended or supplemental indenture is authorized or permitted by this Indenture.

ACCORDANCE WITH ALL APPLICABLE SECURITIES LAWS OF THE STATES OF THE UNITED
STATES."(2)

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

      1. INTEREST. Charter Communications Holdings, LLC, a Delaware limited
liability company (the "Company"), and Charter Communications Holdings Capital
Corporation, a Delaware corporation ("Charter Capital" and, together with the
Company, the "Issuers"), promise to pay interest on the principal amount of this
Note at the rate of 10.750% per annum from January 10, 2001 until maturity. The
interest rate on the Notes is subject to increase pursuant to the provisions of
the Registration Rights Agreement. The Issuers will pay interest semi-annually
in arrears on April 1 and October 1 of each year (each an "Interest Payment
Date"), or if any such day is not a Business Day, on the next succeeding
Business Day. 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 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 October 1, 2001. The Issuers 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; they
shall pay interest (including post-petition interest in any proceeding under any
Bankruptcy Law) on overdue installments of interest (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 Issuers shall pay interest on the Notes (except
defaulted interest) to the Persons who are registered Holders of Notes at the
close of business on the March 15 or September 15 next preceding the Interest
Payment Date, even if such Notes are canceled after such record date and on or
before such Interest Payment Date, except as provided in Section 2.12 of the
Indenture with respect to defaulted interest. The Notes will be payable as to
principal, premium, if any, and interest at the office or agency of the Issuers
maintained for such purpose within or without the City and State of New York,
or, at the option of the Issuers, payment of interest 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

     to the terms of a Registration Rights Agreement.

be required with respect to principal of and interest and premium on all Global
Notes and all other Notes the Holders of which shall have provided wire transfer
instructions to the Issuers 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, BNY Midwest Trust Company, the
Trustee under the Indenture, will act as Paying Agent and Registrar. The Issuers
may change any Paying Agent or Registrar without notice to any Holder. The
Company or any of its Subsidiaries may act in any such capacity.

      4. INDENTURE. The Issuers issued the Notes under an Indenture dated as of
January 10, 2001 (the "Indenture") between the Issuers and the Trustee. The
terms of the Notes include those stated in the Indenture and those made part of
the Indenture by reference to the Trust Indenture Act of 1939, as amended (15
U.S. Code ss.ss. 77aaa-77bbbb). The Notes are subject to all such terms, and
Holders are referred to the Indenture and such Act for a statement of such
terms. To the extent any provision of this Note conflicts with the express
provisions of the Indenture, the provisions of the Indenture shall govern and be
controlling.

      5. OPTIONAL REDEMPTION.

      The Notes will not be redeemable at the Issuers' option prior to maturity.

      6. MANDATORY REDEMPTION.

      Except as otherwise provided in Paragraph 7 below, the Issuers shall not
be required to make mandatory redemption payments with respect to the Notes.

      7. REPURCHASE AT OPTION OF HOLDER.

      (a) If there is a Change of Control, the Issuers shall 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
thereon, if any, to the date of purchase (the "Change of Control Payment").
Within 10 days following any Change of Control, the Issuers shall mail a notice
to each Holder describing the transaction or transactions that constitute the
Change of Control and offering to repurchase Notes on the Change of Control
Payment Date specified in such notice, pursuant to the procedures required by
the Indenture and described in such notice.

      (b) If the Company or a Restricted Subsidiary consummates any Asset Sale,
when the aggregate amount of Excess Proceeds exceeds $25.0 million, the Issuers
shall commence an offer (an "Asset Sale Offer") pursuant to Section 4.11 of the
Indenture to

                                      A-5
<PAGE>   98
all Holders of Notes and all holders of other Indebtedness that is pari passu
with the Notes containing provisions requiring offers to purchase or redeem with
the proceeds of sales of assets to purchase the maximum principal amount of
Notes and such other pari passu Indebtedness that may be purchased out of the
Excess Proceeds (which amount includes the entire amount of the Net Proceeds).
The offer price in any Asset Sale Offer will be payable in cash and equal to
100% of principal amount plus accrued and unpaid interest, if any, to the date
of purchase. 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 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. Upon completion of
each Asset Sale Offer, the amount of Excess Proceeds shall be reset at zero.
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. 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
Issuers may require a Holder to pay any taxes and fees required by law or
permitted by the Indenture. The Issuers 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 Issuers
need not exchange or register the transfer of any Notes for a period of 15 days
before a selection of Notes to be redeemed or during the period between a record
date and the corresponding Interest Payment Date.

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

      10. AMENDMENT, SUPPLEMENT AND WAIVER. Subject to certain exceptions, the
Indenture or the Notes may be amended or supplemented with the consent of the
Holders of at least a majority in aggregate principal amount of the Notes then
outstanding (including, without limitation, consents obtained in connection with
a purchase of, or tender offer or exchange offer for, Notes), and any existing
default or compliance with any provision of the Indenture or the Notes may be
waived with the consent of the Holders of a majority in aggregate principal
amount of the Notes then outstanding (including, without limitation, consents
obtained in connection with a purchase of, or tender offer or exchange offer
for, Notes). Without the consent of any Holder of a Note, the Issuers and the
Trustee may amend or supplement the Indenture or

                                      A-6
<PAGE>   99
the Notes to cure any ambiguity, defect or inconsistency, to provide for
uncertificated Notes in addition to or in place of certificated Notes, to
provide for the assumption of an Issuers' obligations to Holders of Notes in the
case of a merger or consolidation or sale of all or substantially all of the
assets of either Issuer to make any change that would provide any additional
rights or benefits to the Holders of Notes or that does not adversely affect the
legal rights under the Indenture of any such Holder, or to comply with the
requirements of the SEC in order to effect or maintain the qualification of the
Indenture under the TIA or otherwise as necessary to comply with applicable law.

      11. DEFAULTS AND REMEDIES. Each of the following is an Event of Default:
(i) default for 30 days in the payment when due of interest on the Notes, (ii)
default in payment when due of the principal of or premium, if any, on the
Notes, (iii) failure by the Company or any of its Restricted Subsidiaries to
comply with Sections 4.16 and 5.01 of the Indenture, (iv) failure by the Company
or any of its Restricted Subsidiaries for 30 days after written notice thereof
has been given to the Company by the Trustee or to the Company and the Trustee
by the Holders of at least 25% of the principal amount of the Notes outstanding
to comply with any of their other covenants or agreements in the Indenture, (v)
default 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
of the Indenture, if that default: (a) is caused by a failure to pay at final
stated maturity the principal amount of such Indebtedness prior to the
expiration of the grace period provided in such Indebtedness on the date of such
default (a "Payment Default"); or (b) results in the acceleration of such
Indebtedness prior to its express maturity, and, in each case, the principal
amount of any such Indebtedness, together with the principal amount of any other
such Indebtedness under which there has been a Payment Default or the maturity
of which has been so accelerated, aggregates $100 million or more, (vi) failure
by the Company or any of its Restricted Subsidiaries to pay final judgments
which are non-appealable aggregating in excess of $100 million (net of
applicable insurance which has not been denied in writing by the insurer), which
judgments are not paid, discharged or stayed for a period of 60 days or (vii)
certain events of bankruptcy or insolvency with respect to the Company or any of
its Significant Subsidiaries. In the case of an Event of Default arising from
certain events of bankruptcy or insolvency with respect to the Company, all
outstanding Notes will become due and payable without further action or notice.
If any other Event of Default occurs and is continuing, the Trustee by notice to
the Issuers or the Holders of at least 25% in principal amount of the then
outstanding Notes by notice to the Issuers and the Trustee may declare all the
Notes to be due and payable. Holders may not enforce the Indenture or the Notes
except as provided in the Indenture. Subject to certain limitations, Holders of
a majority in aggregate principal amount of the then outstanding Notes may
direct the Trustee in its exercise of any trust or power. The Trustee may
withhold from Holders of the Notes notice of any continuing Default or

                                      A-7
<PAGE>   100
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. Upon becoming aware of any Default or Event of Default, the Company
is required to deliver to the Trustee a statement specifying such Default or
Event of Default.

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

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

      14. GOVERNING LAW. THE INTERNAL LAWS OF THE STATE OF NEW YORK SHALL GOVERN
AND BE USED TO CONSTRUE THIS NOTE AND THE INDENTURE WITHOUT GIVING EFFECT TO THE
APPLICABLE PRINCIPLES OF CONFLICTS OF LAWS TO THE EXTENT THAT THE APPLICATION OF
THE LAWS OF ANOTHER JURISDICTION WOULD BE REQUIRED THEREBY. EACH OF THE PARTIES
HERETO AND THE HOLDERS AGREE TO SUBMIT TO THE JURISDICTION OF THE COURTS OF THE
STATE OF NEW YORK IN ANY ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO THIS
NOTE.

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

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

      17. ADDITIONAL RIGHTS OF HOLDERS OF RESTRICTED GLOBAL NOTES AND RESTRICTED
DEFINITIVE NOTES. In addition to the rights provided to

                                      A-8
<PAGE>   101
Holders of Notes under the Indenture, Holders of Restricted Global Notes and
Restricted Definitive Notes shall have all the rights set forth in any
Registration Rights Agreement.

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

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