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

               (c) Euroclear and Cedel Procedures Applicable. The provisions of
the "Operating Procedures of the Euroclear System" and "Terms and Conditions
Governing Use of Euroclear" and the "General Terms and Conditions of Cedel Bank"
and "Customer Handbook" of Cedel Bank shall be applicable to transfers of
beneficial interests in the Regulation S Global Notes that are held by
Participants through Euroclear or Cedel Bank.

Section 2.02. Execution and Authentication.

               Two Officers shall sign the Notes for each Issuer by manual or
facsimile signature.

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

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

               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 $325,000,000 and (ii) Additional Notes from time to time for original
issue in aggregate principal amount specified by the Issuers not to exceed
$175,000,000 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 

<PAGE>   36

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 outstanding at any time may not exceed $500,000,000
except as provided in Section 2.07. On the Issue Date, the Issuers will issue
$325,000,000 aggregate principal amount of Initial 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 

<PAGE>   37

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 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.

<PAGE>   38

               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.
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
               Applicable Procedures containing information regarding the
               Participant account to be credited with such increase; or

<PAGE>   39

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

                             (B)(2) instructions given by the Depositary to the
               Registrar containing information regarding the Person in whose
               name such Definitive Note shall be registered to effect the
               transfer or exchange referred to in (1) above. Upon consummation
               of an Exchange Offer by the Issuers in accordance with Section
               2.06(f), the requirements of this Section 2.06(b)(ii) shall be
               deemed to have been satisfied upon receipt by the Registrar of
               the instructions contained in the Letter of Transmittal delivered
               by the holder of such beneficial interests in the Restricted
               Global Notes. Upon satisfaction of all of the requirements for
               transfer or exchange of beneficial interests in Global Notes
               contained in this Indenture and the Notes or otherwise applicable
               under the Securities Act, the Trustee shall adjust the principal
               amount of the relevant Global Note(s) pursuant to Section
               2.06(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 of a beneficial interest in the 144A Global Note, then the
               transferor must deliver a certificate in the form of Exhibit B
               hereto, including the certifications in item (1) thereof; and

                             (B) if the transferee will take delivery in the
               form of a beneficial interest in the Regulation S Global Note,
               then the transferor must deliver a certificate in the form of
               Exhibit B hereto, including the certifications in item (2)
               thereof.

                      (iv) Transfer and Exchange of Beneficial Interests in a
        Restricted Global Note for Beneficial Interests in an Unrestricted
        Global Note. A beneficial interest in any Restricted Global Note may be
        exchanged by any holder thereof for a beneficial interest in an
        Unrestricted Global Note or transferred to a Person who takes delivery
        thereof in the form of a beneficial interest in an Unrestricted Global
        Note if the exchange or transfer complies with the requirements of
        Section 2.06(b)(ii) above and:

                             (A) such exchange or transfer is effected pursuant

               of the beneficial interest to be transferred, in the case of an
               exchange, or the transferee, in the case of a transfer, certifies
               in the applicable Letter of Transmittal that it is not (1) a
               broker-dealer, (2) a Person participating in the distribution of
               the relevant Exchange Notes or (3) a Person who is an affiliate
               (as defined in Rule 144) of the Issuers;

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

                             (C) such transfer is effected by a broker-dealer
               pursuant to the Exchange Registration Statement in accordance
               with a Registration Rights Agreement; or

                                    (1) if the holder of such beneficial
                      interest in a Restricted Global Note proposes to exchange
                      such beneficial interest for a beneficial interest in an
                      Unrestricted Global Note, a certificate from such holder
                      in the form of Exhibit C hereto, including the
                      certifications in item (1)(a) thereof; or

                                    (2) if the holder of such beneficial
                      interest in a Restricted Global Note proposes to transfer
                      such beneficial interest to a Person who shall take

                      holder in the form of Exhibit B hereto, including the
                      certifications in item (4) thereof;

               and, in each such case set forth in this subparagraph (D), if the

               Registrar to the effect that such exchange or transfer is in
               compliance with the Securities Act and that the restrictions on
               transfer contained herein and in the Private Placement Legend are
               no longer required in order to maintain compliance with the
               Securities Act.

                      If any such transfer is effected pursuant to subparagraph
        (B) or (D) above at a time when an Unrestricted Global Note has not yet
        been issued, the Issuers shall issue and, upon receipt of an
        Authentication Order in accordance with Section 2.02, the Trustee shall
        authenticate one or more Unrestricted Global Notes in an aggregate
        principal amount equal to the aggregate principal amount of beneficial
        interests transferred pursuant to subparagraph (B) or (D) above.

                      (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 (A) to issue, to
        register the transfer of or to exchange any Notes during a period
        beginning at the opening of business 15 days before the day of any
        selection of Notes for redemption under Section 3.02 and ending at the
        close of business on the day of selection, (B) to register the transfer
        of or to exchange any Note so selected for redemption in whole or in
        part, except the unredeemed portion of any Note being redeemed in part
        or (C) to register the transfer of or to exchange a Note between a
        record date and the next succeeding Interest Payment Date.

                      (vi) Prior to due presentment for the registration of a
        transfer of any Note, 

<PAGE>   51

        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.

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

Section 2.07. Replacement Notes.

               If any mutilated Note is surrendered to the Trustee or the
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 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, 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; however, Notes held by an Issuer or a Subsidiary of an Issuer
shall not be deemed to be outstanding for purposes of Section 3.07(b).

               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.

<PAGE>   52

               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.

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 destroy
canceled Notes. Certification of the destruction of all canceled Notes shall be
delivered to the Issuers. The Issuers may not issue new Notes to replace Notes
that they have paid or that have been delivered to the Trustee for cancellation.

<PAGE>   53

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.

                       ARTICLE 3 REDEMPTION AND PREPAYMENT

Section 3.01. Notices to Trustee.

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

Section 3.02. Selection of Notes to Be Redeemed.

               If less than all of the Notes are to be redeemed or purchased in
an offer to purchase at any time, the Trustee shall select the Notes to be
redeemed or purchased among the Holders of the Notes in compliance with the
requirements of the principal national securities exchange, if any, on which the
Notes are listed or, if the Notes are not so listed, on a pro rata basis, by lot
or in accordance with any other method the Trustee considers fair and
appropriate. In the event of partial redemption by lot, the particular Notes to
be redeemed shall be selected, unless otherwise provided herein, not less than
30 nor more than 60 days prior to the redemption date by the Trustee from the
outstanding Notes not previously called for redemption.

               The Trustee shall promptly notify the Issuers in writing of the
Notes selected for redemption and, in the case of any Note selected for partial
redemption, the principal amount thereof to be redeemed. Notes and portions of
Notes selected shall be in amounts

<PAGE>   54

of $1,000 or whole multiples of $1,000; except that if all of the Notes of a
Holder are to be redeemed, the entire outstanding amount of Notes held by such
Holder, even if not a multiple of $1,000, shall be redeemed. Except as provided
in the preceding sentence, provisions of this Indenture that apply to Notes
called for redemption also apply to portions of Notes called for redemption.

Section 3.03. Notice of Redemption.

               Subject to the provisions of Section 3.09, at least 30 days but
not more than 60 days before a redemption date, the Issuers shall mail or cause
to be mailed, by first class mail, a notice of redemption to each Holder whose
Notes are to be redeemed at its registered address.

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

               (a) the redemption date;

               (b) the redemption price;

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

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

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

               (f) that, unless the Issuers default in making such redemption
payment, interest on Notes called for redemption ceases to accrue on and after
the redemption date;

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

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

               At the Issuers' request, the Trustee shall give the notice of
redemption in the Issuers' name and at their expense; provided, however, that
each of the Issuers shall have delivered to the Trustee, at least 45 days prior
to the redemption date, an Officers' Certificate requesting that the Trustee
give such notice and setting forth the information 

<PAGE>   55

to be stated in such notice as provided in the preceding paragraph.

Section 3.04. Effect of Notice of Redemption.

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

Section 3.05. Deposit of Redemption Price.

               At or prior to 10:00 a.m., New York City time, on the redemption
date, the Issuers shall deposit with the Trustee or with the Paying Agent money
sufficient to pay the redemption price of and accrued interest on all Notes to
be redeemed on that date. The Trustee or the Paying Agent shall promptly return
to the Issuers any money deposited with the Trustee or the Paying Agent by the
Issuers in excess of the amounts necessary to pay the redemption price of, and
accrued interest on, all Notes to be redeemed.

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

Section 3.06. Notes Redeemed in Part.

               Upon surrender of a Note that is redeemed in part, the Issuers
shall issue and, upon the Issuers' written request, the Trustee shall
authenticate for the Holder at the expense of the Issuers a new Note equal in
principal amount to the unredeemed portion of the Note surrendered.

Section 3.07. Optional Redemption.

               (a) Except as set forth in clause (b) of this Section 3.07, the
Issuers shall not have the option to redeem the Notes pursuant to this Section
3.07 prior to January 15, 2005. Thereafter, the Issuers shall have the option to
redeem the Notes, in whole or in part, upon not less than 30 nor more than 60
days' notice, at the redemption prices 

<PAGE>   56

(expressed as percentages of principal amount) set forth below plus accrued and
unpaid interest thereon, if any, to the applicable redemption date, if redeemed
during the twelve-month period beginning on January 15 of the years indicated
below:

</TABLE>


               (b) Notwithstanding the provisions of clause (a) of this Section
3.07, at any time prior to January 15, 2003, the Issuers may, on any one or more
occasions, redeem up to 35% of the original aggregate principal amount of the
Notes (including the principal amount of any Additional Notes) issued under this
Indenture on a pro rata basis (or nearly as pro rata as practicable) at a
redemption price of 110.25% of the principal amount thereof, plus accrued and
unpaid interest to the redemption date, with the net cash proceeds of one or
more Equity Offerings; provided that

                      (1) at least 65% of the original aggregate principal
        amount of Notes (including the principal amount of any Additional Notes)
        issued under this Indenture remains outstanding immediately after the
        occurrence of such redemption (excluding Notes held by the Company and
        its Subsidiaries and the Guarantor and its Subsidiaries); and

                      (2) the redemption must occur within 60 days of the date
        of the closing of such Equity Offering.

               (c) Any redemption pursuant to this Section 3.07 shall be made
pursuant to the provisions of Section 3.01 through 3.06.

Section 3.08. Mandatory Redemption.

               Except as otherwise provided in Section 4.11 or Section 4.16
below, the Issuers shall not be required to make mandatory redemption payments
with respect to the Notes.

Section 3.09. 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 

<PAGE>   57

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 3.09 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;

               (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 

<PAGE>   58

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 3.09. 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.

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

Section 4.01. Payment of Notes.

<PAGE>   59

               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
Special Interest, if any, in the same manner on the dates and in the amounts set
forth in any Registration Rights Agreement.

               The Issuers shall pay interest (including post-petition interest
in any proceeding under any Bankruptcy Law) on overdue principal at the rate
equal to 1% per annum in excess of the then applicable interest rate on the
Notes to the extent lawful; 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 period) at the same rate to the
extent lawful.

Section 4.02. Maintenance of Office or Agency.

               The Issuers shall maintain in the Borough of Manhattan, the City

affiliate of the Trustee, Registrar or co-registrar) where Notes may be
surrendered for registration of transfer or for exchange and where notices and
demands to or upon the 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.

               The Issuers hereby designate the Harris Trust Company of New
York, an affiliate of the Trustee, as one such office or agency of the Issuers
in accordance with Section 2.03.

Section 4.03. Reports.

<PAGE>   60

               Whether or not required by the Commission, so long as any Notes

the Commission on Form 8-K if the Issuers were required to file such reports.

               If the Issuers have designated any of their Subsidiaries as
Unrestricted Subsidiaries, then the quarterly and annual financial information
required by the preceding paragraph shall include a reasonably detailed
presentation, either on the face of the financial statements or in the footnotes
thereto, and in Management's Discussion and Analysis of Financial Condition and
Results of Operations, of the financial condition and results of operations of
the Company and its Restricted Subsidiaries separate from the financial
condition and results of operations of the Unrestricted Subsidiaries of the
Company.

               In addition, whether or not required by the Commission, the
Issuers shall file a copy of all of the information and reports referred to in
clauses (1) and (2) above with the Commission for public availability within the
time periods specified in the Commission's rules and regulations (unless the
Commission will not accept such a filing) and make such information available to
securities analysts and prospective investors upon request.

Officers with a view to determining whether the Company has kept, observed,
performed and fulfilled its obligations under this Indenture, and further
stating, as to each such Officer signing such certificate, that to the best of
his or her knowledge the Company has kept, observed, performed and fulfilled
each and every covenant contained in this Indenture and is not in default in the

of his or her knowledge no event has occurred and remains in existence by reason
of which payments on account of the principal of or interest, if any, on the
Notes is prohibited or if such event has occurred, a description of the event
and what action the Company is taking or proposes to take with respect thereto.

               (b) So long as not contrary to the then current recommendations
of the American Institute of Certified Public Accountants, the year-end
financial statements delivered pursuant to Section 4.03 above shall be
accompanied by a written statement of the Company's independent public
accountants (each of whom shall be a firm of established national reputation)
that in making the examination necessary for certification of such financial
statements, nothing has come to their attention that would lead them to believe
that the Company has violated any provisions of Article 4 or Article 5 or, if
any such violation has occurred, specifying the nature and period of existence
thereof, it being understood that such accountants shall not be liable directly
or indirectly to any Person for any failure to obtain knowledge of any such
violation. In the event that, after the Company has used its reasonable best
efforts to obtain the written statement of the Company's independent public
accountants required by the provisions of this paragraph, such statement cannot
be obtained, the Company shall deliver, in satisfaction of its obligations under
this Section 4.04, an Officers' Certificate (A) certifying that it has used its
reasonable best efforts to obtain such required statement but was unable to do
so and (B) attaching the written statement of the Company's accountants that the
Company received in lieu thereof.

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

Section 4.05. Taxes.

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

Section 4.06. Stay, Extension and Usury Laws.

               Each of the Issuers covenants (to the extent that it may lawfully
do so) that it shall not at any time insist upon, plead, or in any manner
whatsoever claim or take the 

<PAGE>   62

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

Section 4.07. Restricted Payments.

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

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

               (b) purchase, redeem or otherwise acquire or retire for value
(including, without limitation, in connection with any merger or consolidation
involving the Company) any Equity Interests of the Company or any direct or
indirect parent of the Company or any Restricted Subsidiary of the Company
(other than any such Equity Interests owned by the Company or any Restricted
Subsidiary of the Company); or

               (c) make any payment on or with respect to, or purchase, redeem,
defease or otherwise acquire or retire for value, any Indebtedness that is
subordinated to the Notes, except a payment of interest or principal at the
Stated Maturity thereof (all such payments and other actions set forth in
clauses (a) through (c) above being collectively referred to as "Restricted
Payments"), unless, at the time of and after giving effect to such Restricted
Payment:

                      (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 such Restricted
        Payment and after giving pro forma effect thereto as if such Restricted
        Payment had been made at the beginning of the applicable quarter period,
        have been permitted to incur at least 

<PAGE>   63

        $1.00 of additional Indebtedness pursuant to the Leverage Ratio test set
        forth in the first paragraph of Section 4.10; and

                      (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 the Existing Notes Issue Date
        (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 the Existing Notes Issue Date 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 the Existing
               Notes Issue Date 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;

                      (3) the defeasance, redemption, repurchase or other
        acquisition of subordinated Indebtedness of the Company or any of its
        Restricted Subsidiaries with 

<PAGE>   64

        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
        stock option agreement in effect as of the date of this Indenture;
        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
Director's 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 Payment, the Company shall deliver to the Trustee an Officers'
Certificate stating that such 

<PAGE>   65

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 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 the covenant described
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 

<PAGE>   66

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 the Indenture to be incurred;

<PAGE>   67

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

               (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 pursuant to the provisions of the covenant described above 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 

<PAGE>   68

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 their
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 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 the Existing Notes Issue Date 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;

<PAGE>   69

               (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

                      (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 the Indentures 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 the Existing Notes Issue Date 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 

<PAGE>   70

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 on the date of its incurrence 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.

               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;

<PAGE>   71

               (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.

               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.

               Any Net Proceeds from Asset Sales that are not applied or
invested as provided in the preceding paragraph shall constitute "Excess
Proceeds." When the aggregate 

<PAGE>   72

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 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 3.09.

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, the covenant described above under Section 4.11.

               The foregoing restrictions do 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

<PAGE>   73

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:

                      (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 covenant 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 

<PAGE>   74

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 trade payables on any asset now owned or hereafter
acquired, except Permitted Liens.

Section 4.15. Corporate 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
corporate existence, and the corporate, partnership or other existence of each
of its Subsidiaries, in accordance with the respective organizational documents
(as the same may be amended from time to time) of the Company 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:

<PAGE>   75

               (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;

               (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 

<PAGE>   76

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.

               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 

<PAGE>   77

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 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.

                              ARTICLE 5 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 

<PAGE>   78

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 other 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 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.

                         ARTICLE 6 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;

               (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 

<PAGE>   80

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:

                      (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 

<PAGE>   81

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, 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 unduly
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.

<PAGE>   82

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

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

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

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

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

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

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

Section 6.07. Rights of Holders of Notes to Receive Payment.

               Notwithstanding any other provision of this Indenture, the right
of any Holder of a Note to receive payment of principal, premium, 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.

<PAGE>   83

               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

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

               In any suit for the enforcement of any right or remedy under this
Indenture or in any suit against the Trustee for any action taken or omitted by
it as a Trustee, a court in its discretion may require the filing by any party
litigant in the suit of an undertaking to pay the costs of the suit, and the
court in its discretion may assess reasonable costs, including reasonable
attorneys' fees, against any party litigant in the suit, having due regard to
the merits and good faith of the claims or defenses made by the party litigant.
This Section 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.

                                ARTICLE 7 TRUSTEE

Section 7.01. Duties of Trustee.

               (a) If an Event of Default has occurred and is continuing, the
Trustee shall exercise such of the rights and powers vested in it by this
Indenture, and use the same degree of care and skill in its exercise, as a
prudent person would exercise or use under the circumstances in the conduct of
such person's own affairs.

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

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

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

               (c) The Trustee may not be relieved from liabilities for its own
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;

<PAGE>   85

                      (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

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

               (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.

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

reliance on such Officers' Certificate or Opinion of Counsel. The Trustee may
consult with counsel and the written advice of such counsel or any Opinion of
Counsel 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.

<PAGE>   86

               (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

               (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

reasonable security or indemnity 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

written notice of such Default or Event of Default shall have been given to the
Trustee by the Issuers or any Holder.

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

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.

<PAGE>   87

Section 7.05. Notice of Defaults.

               If a Default or Event of Default occurs and is continuing and if
it is known to the Trustee, the Trustee shall mail to Holders of Notes a notice
of the Default or Event of Default within 90 days after 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.

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 or 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 

<PAGE>   88

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;

<PAGE>   89

               (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 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. 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 

<PAGE>   90

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 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 

<PAGE>   91

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 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:

<PAGE>   92

               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;

               (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 the Restricted Subsidiaries is a party or by which the Company or any of the
Restricted Subsidiaries is bound;

               (6) the Company must have delivered to the applicable 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 

<PAGE>   93

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 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 

<PAGE>   94

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 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.

<PAGE>   95

               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 such 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 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

<PAGE>   96

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):

               (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 

<PAGE>   97

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 one of the covenants described in 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 

<PAGE>   98
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.

                            ARTICLE 10 MISCELLANEOUS

Section 10.01. Trust Indenture Act Controls.

               If any provision of this Indenture limits, qualifies or conflicts

               giving of notice of redemption by the Trustee in the name, and at

        and the Issuers, in the case of (i), (ii) or (iii) above, have deposited

<PAGE>   110

               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 10.25% per annum from January 12, 2000 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 January 15 and July 15 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 July 15, 2000. 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 January 1 or July 1 next preceding the Interest
Payment Date, even if such Notes are canceled after such record date and on or
before such Interest Payment Date, except as provided in Section 2.12 of the
Indenture with respect to defaulted interest. The Notes will be payable as to
principal, premium, 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
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, Harris Trust and
Savings

<PAGE>   111

Bank, 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 12, 2000 ("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. The Notes are obligations of the Issuers limited to $500,000,000
million in principal amount, of which $325,000,000 million in aggregate
principal amount of Notes was issued on the Issue Date.

               5. OPTIONAL REDEMPTION.

               (a) Except as set forth in clause (b) of this Paragraph 5, the
Issuers shall not have the option to redeem the Notes prior to January 15, 2005.
Thereafter, the Issuers shall have the option to redeem the Notes, in whole or
in part, upon not less than 30 nor more than 60 days' notice, at the redemption
prices (expressed as percentages of principal amount) set forth below plus
accrued and unpaid interest thereon, if any, to the applicable redemption date,
if redeemed during the twelve-month period beginning on January 15 of the years
indicated below:

                    Year                                    Percentage
                    ----                                    ----------
          2005                                               105.125%
          2006                                               103.417%
          2007                                               101.708%
          2008 and thereafter                                100.000%

               (b) Notwithstanding the provisions of clause (a) of this
Paragraph 5, at any time prior to January 15, 2003, the Issuers may on any one
or more occasions redeem up to 35% of the original aggregate principal amount of
the Notes (including the principal amount of any Additional Notes) issued under
the Indenture on a pro rata basis (or as nearly pro rata as practicable), at a
redemption price of 110.25% of the principal amount thereof, plus accrued and
unpaid interest to the redemption date, with the net cash proceeds of one or
more Equity Offerings; provided that

                      (1) at least 65% of the original aggregate principal 
        amount of Notes (including the principal amount of any Additional Notes)
        issued under the Indenture remains outstanding immediately after the 
        occurrence of such redemption (excluding Notes 

<PAGE>   112

held by the Company and its Subsidiaries); and

                      (2) the redemption must occur within 60 days of the date 
        of the closing of such Equity Offering.

               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 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

<PAGE>   113

the Notes.

               8. NOTICE OF REDEMPTION. Notice of redemption will be mailed by
first class mail at least 30 days but not more than 60 days before the
redemption date to each Holder whose Notes are to be redeemed at its registered
address. Notices of redemption may not be conditional. No Notes of $1,000 or
less may be redeemed in part. Notes in denominations larger than $1,000 may be
redeemed in part but only in whole multiples of $1,000, unless all of the Notes
held by a Holder are to be redeemed. On and after the redemption date interest
ceases to accrue on Notes or portions thereof called for redemption.

               9. DENOMINATIONS, TRANSFER, EXCHANGE. The Notes are in registered
form without coupons in denominations of $1,000 and integral multiples of
$1,000. The transfer of Notes may be registered and Notes may be exchanged as
provided in the Indenture. The Registrar and the Trustee may require a Holder,
among other things, to furnish appropriate endorsements and transfer documents
and the 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.

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

               11. AMENDMENT, SUPPLEMENT AND WAIVER. Subject to certain
exceptions, the Indenture 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 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 

<PAGE>   114

under the TIA or otherwise as necessary to comply with applicable law.

               12. 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 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 

<PAGE>   115

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.

               13. 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.

               14. 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.

               15. GOVERNING LAW. This Note and the Indenture shall be governed
by and construed in accordance with the laws of the State of New York, as
applied to contracts made and performed within the State of New York, without
regard to principles of conflict of laws. 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.

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

               17. 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).

               18. ADDITIONAL RIGHTS OF HOLDERS OF RESTRICTED GLOBAL NOTES AND
RESTRICTED DEFINITIVE NOTES. In addition to the rights provided to Holders of
Notes under the Indenture, Holders of Restricted Global Notes and Restricted
Definitive Notes shall have all the rights set forth in any Registration Rights
Agreement.

               19. 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 

<PAGE>   116

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.
