                                       -8-

<PAGE>

when such instrument or instruments are delivered to the Trustee and,
where it is hereby expressly required, to the Issuers or the Guarantor. Such
instrument or instruments (and the action embodied therein and evidenced
thereby) are herein sometimes referred to as the "Act" of the Holders signing
such instrument or instruments. Proof of execution of any such instrument or of
a writing appointing any such agent shall be sufficient for any purpose of this
Indenture and (subject to Section 601) conclusive in favor of the Trustee and
the Issuers or the Guarantor, if made in the manner provided in this Section.

Committee and/or a Board Resolution, as the case may be, fix in advance a record
date for the determination of Holders entitled to give such request, demand,
authorization, direction, notice, consent, waiver or other Act, but the Issuers
or the Guarantor shall have no obligation to do so. Notwithstanding Trust
Indenture Act Section 316(c), such record date shall be the record date
specified in or pursuant to such Committee Resolution and/or Board Resolution,
which shall be a date not earlier than the date 30 days prior to the first
solicitation of Holders generally in connection therewith and not later than the
date such solicitation is completed. If such a record date is fixed, such
request, demand, authorization, direction, notice, consent, waiver or other Act
maybe given before or after such record date, but only the Holders of record at
the close of business on such record date shall be deemed to be Holders for the
purposes of determining whether Holders of the requisite proportion of
Outstanding Securities shall be computed as of such record date; provided,
however, that no such authorization, agreement or consent by such Holders on
such record date shall be deemed effective unless it shall become effective
pursuant to the provisions of this Indenture not later than eleven months after
the record date.

         (e) Any request, demand, authorization, direction, notice, consent,
waiver or other Act of the Holder of any Security shall bind every future Holder
of the same Security and the Holder of every Security issued upon the
registration of transfer thereof or in exchange therefor or in lieu thereof in
respect of anything done, omitted or suffered to be done by the Trustee or the
Issuers or the Guarantor in reliance thereon, whether or not notation of such
action is made upon such Security.

Section 105.      Notices, Etc., to Trustee, the Issuers and the Guarantor.

         Any request, demand, authorization, direction, notice, consent, waiver
or Act of Holders or other document provided or permitted by this Indenture to
be made upon, given or furnished to, or filed with,

                  (1) the Trustee by any Holder or by the Issuers or the
         Guarantor shall be sufficient for every purpose hereunder if made,
         given, furnished or filed in writing to or with the Trustee at its
         Corporate Trust Office, Attention: Corporate Trust Department, or

                                       -9-

<PAGE>

                  (2) the Issuers or the Guarantor by the Trustee or by any
         Holder shall be sufficient for every purpose hereunder (unless
         otherwise herein expressly provided) if in writing and mailed,
         first-class postage prepaid, to the Issuers or the Guarantor, as the
         case may be, addressed to them or it at the address of their or its
         principal office specified in the first paragraph of this instrument or
         at any other address previously furnished in writing to the Trustee by
         the Issuers or the Guarantor, to the attention of the general counsel
         of the Issuers or the Guarantor, as the case may be.

Section 106.      Notice to Holders; Waiver.

         Where this Indenture provides for notice to Holders of any event, such
notice shall be sufficiently given (unless otherwise herein expressly provided)
if in writing and mailed, first-class postage prepaid, to each Holder affected
by such event, at his address as it appears in the Security Register, not later
than the latest date, and not earlier than the earliest date, prescribed for the
giving of such notice. In any case where notice to Holders is given by mail,
neither the failure to mail such notice, nor any defect in any notice so mailed,
to any particular Holder shall affect the sufficiency of such notice with
respect to other Holders. Where this Indenture provides for notice in any
manner, such notice may be waived in writing by the Person entitled to receive
such notice, either before or after the event, and such waiver shall be the
equivalent of such notice. Waivers of notice by Holders shall be filed with the
Trustee, but such filing shall not be a condition precedent to the validity of
any action taken in reliance upon such waiver.

         In case by reason of the suspension of regular mail service or by
reason of any other case it shall be impracticable to give such notice by mail,
then such notification as shall be made with the approval of the Trustee shall
constitute a sufficient notification for every purpose hereunder.

Section 107.      Effect of Headings and Table of Contents.

         The Article and Section headings herein and the Table of Contents are
for convenience only and shall not affect the construction hereof.

Section 108.      Successors and Assigns.

         All covenants and agreements in this Indenture by each of the Issuers
or the Guarantor shall bind each of its successors and assigns, whether so
expressed or not.

Section 109.      Separability Clause.

         In case any provision in this Indenture, the Securities or the
Guarantee shall be invalid, illegal or unenforceable, the validity, legality and
enforceability of the remaining provisions shall not in any way be affected or
impaired thereby.

                                      -10-

Section 110.      Benefits of Indenture.

         Nothing in this Indenture, the Securities or the Guarantee, express or
implied, shall give to any Person (other than the parties hereto, any agent and
their successors hereunder and each of the Holders) any benefit or any legal or
equitable right, remedy or claim under this Indenture.

Section 111.      Conflict with Trust Indenture Act.

         If any provision hereof limits, qualifies or conflicts with another
provision which is required or deemed to be included in this Indenture by any of
the provisions of the Trust Indenture Act, such required or deemed provision
shall control.

Section 112.      Governing Law.

         This Indenture, the Securities and the Guarantee shall be governed by
and construed in accordance with the laws of the State of New York.

Section 113.      Legal Holidays.

         In any case where any Interest Payment Date, Redemption Date or Stated
Maturity of any Security shall not be a Business Day at any Place of Payment,
then (notwithstanding any other provision of this Indenture or of the
Securities) payment of interest or principal (and premium, if any) need not be
made at such Place of Payment on such date, but may be made on the next
succeeding Business Day at such Place of Payment with the same force and effect
as if made on the Interest Payment Date or Redemption Date, or at the Stated
Maturity, provided that no interest shall accrue for the period from and after
such Interest Payment Date, Redemption Date or Stated Maturity, as the case may
be.

Section  114.     No Personal Liability of Directors, Officers, Employees,
                  Stockholders or Incorporators.

         No manager, director, officer, employee, member, shareholder, partner
or incorporator of the Issuers or the Guarantor or any Subsidiary, as such,
shall have any liability for any obligations of the Issuers or the Guarantor
under the Securities, this Indenture or for any claim based on, in respect of,
or by reason of, such obligations or their creation. Each Holder by accepting a
Security waives and releases all such liability. Such waiver and release are
part of the consideration for the issuance of the Securities of each series.

         notifies the Issuers that it is unwilling or unable to continue as
         Depositary for such Global Security or if at any time the Depositary

         delivery of individual Securities of such series in exchange for such
         Global Security, will authenticate and deliver individual Securities of
         such series of like tenor and terms in definitive form in an aggregate
         principal amount equal to the principal amount of the Global Security
         in exchange for such Global Security and the Guarantor shall execute

                  (3) The Issuers may at any time and in their sole discretion
         determine that the Securities of any series issued or issuable in the
         form of one or more Global Securities shall no longer be represented by
         such Global Security or Securities. In such event the Issuers will
         execute, and the Trustee, upon receipt of an Issuers Order for the
         authentication and delivery of individual Securities of such series in
         exchange in whole or in part for such Global Security, will
         authenticate and deliver individual Securities of such series of like
         tenor and terms in definitive form in an aggregate principal amount
         equal to the principal amount of such Global Security or Securities
         representing such series to be so exchanged for such Global Security or
         Securities and the Guarantor shall execute Guarantees thereon.

                  (4) If specified by the Issuers pursuant to Section 301 with

         Global Security in exchange in whole or in part for individual
         Securities of such series of like tenor and terms in definitive form on
         such terms as are acceptable to the Issuers and such Depositary.

         thereof as requested by such Person in aggregate principal amount equal
         to and in exchange for such Person's beneficial interest in the Global
         Security; and (ii) to such Depositary a new Global Security of like
         tenor and terms and in a denomination equal to the difference, if any,
         between the principal amount of the surrendered Global Security and the
         aggregate principal amount of Securities delivered to Holders thereof.

                  (5) In any exchange provided for in any of the preceding four
         paragraphs, the Issuers will execute, the Guarantor shall execute
         Guarantees on, and the Trustee will authenticate and deliver individual
         Securities in definitive registered form in authorized denominations of
         $1,000 and any integral multiple thereof. Upon the exchange of a Global
         Security for individual Securities, such Global Security shall be
         cancelled by the Trustee. Securities issued in exchange for a Global
         Security pursuant to this Section shall be registered in such names and
         in such authorized denominations as the Depositary for such Global
         Security, pursuant to instructions from its direct or indirect
         participants or otherwise, shall instruct the Trustee. The Trustee
         shall deliver such Securities to the persons in whose names such
         Securities are so registered.

<PAGE>

vice presidents, under its corporate seal reproduced thereon attested by its
secretary or one of its assistant secretaries. The signature of any of these
officers on the Securities may be manual or facsimile.

         Securities bearing the manual or facsimile signatures of individuals

notwithstanding that such individuals or any of them have ceased to hold such
offices prior to the authentication and delivery of such Securities or did not

         At any time and from time to time after the execution and delivery of
this Indenture, the Issuers may deliver Securities of any series executed by the
Issuers to the Trustee for authentication, together with an Issuers Order for

Resolutions as permitted by Sections 201 and 301, or by one or more indentures
supplemental hereto as provided by Section 901, in authenticating such
Securities, and accepting the additional responsibilities under this Indenture
in relation to such Securities, the Trustee shall be entitled to receive, and
(subject to Section 601) shall be fully protected in relying upon, an Opinion of
Counsel stating,

                  (1) that such form has been established in conformity with the
         provisions of this Indenture;

                  (2) that such terms have been established in conformity with
         the provisions of this Indenture;

                  (3) that this Indenture and such Securities, when
         authenticated and delivered by the Trustee and issued by the Issuers in
         the manner and subject to any conditions specified in such Opinion of
         Counsel, will constitute valid and legally binding obligations of the
         Issuers, enforceable in accordance with their terms, subject to
         bankruptcy, insolvency, fraudulent conveyance, reorganiztion and other
         laws of general applicability relating to or affecting the enforcement
         of creditors' rights and to general equity principles;

                  (4) that all laws and requirements in respect of the execution
         and delivery by the Issuers of the Securities have been complied with;
         and

                  (5) such other matters as the Trustee may reasonably request.

         If such form or terms have been so established, the Trustee shall not
be required to authenticate such Securities if the issue of such Securities
pursuant to this Indenture will affect the Trustee's own rights, duties or
immunities under the Securities and this Indenture or otherwise in a manner
which is not reasonably acceptable to the Trustee.

         Each Security shall be dated the date of its authentication unless
otherwise provided by the terms established and contemplated by Section 301.

                                      -18-

<PAGE>

         No Security shall be entitled to any benefit under this Indenture or be
valid or obligatory for any purpose unless there appears on such Security a
certificate of authentication substantially in the form provided for herein
executed by the Trustee by manual signature, and such certificate upon any
Security shall be conclusive evidence, and the only evidence, that such Security
has been duly authenticated and delivered hereunder and is entitled to the
benefits of this Indenture.

Section 304.      Temporary Securities.

         Pending the preparation of definitive Securities of any series, the
Issuers may execute, and upon Issuers Order the Trustee shall authenticate and
deliver, temporary Securities which are printed, lithographed, typewritten,
mimeographed or otherwise produced, in any authorized denomination,
substantially of the tenor of the definitive Securities in lieu of which they
are issued and with such appropriate insertions, omissions, substitutions and
other variations as the officers executing such Securities may determine, as
evidenced by their execution of such Securities.

         If temporary Securities of any series are issued, the Issuers will
cause definitive Securities of that series to be prepared without unreasonable
delay. After the preparation of definitive Securities of such series, the
temporary Securities of such series shall be exchangeable for definitive
Securities of such series upon surrender of the temporary Securities of such
series at the office or agency of the Issuers in a Place of Payment for that
series, without charge to the Holder. Upon surrender for cancellation of any one
or more temporary Securities of any series the Issuers shall execute and the
Trustee shall authenticate and deliver in exchange therefor a like principal
amount of definitive Securities of the same series of authorized denominations
and the Guarantor shall execute Guarantees thereon. Until so exchanged the
temporary Securities of any series shall in all respects be entitled to the same
benefits under this Indenture as definitive Securities of such series.

Section 305.      Registration, Registration of Transfer and Exchange.

         The Issuers shall cause to be kept at one of their offices or agencies
maintained pursuant to Section 1002 or at the Corporate Trust Office of the
Trustee a register (the register maintained in such office and in any other
office or agency of the Issuers in a Place of Payment being herein sometimes
collectively referred to as the "Security Register") in which, subject to
Section 203 and to such reasonable regulations as it may prescribe, the Issuers
shall provide for the registration of Securities and of transfers of Securities.
The Trustee initially is hereby appointed "Security Registrar" for the purpose
of registering Securities and transfers of Securities as herein provided. The
Issuers may act as Security Registrar and may change or appoint a Security
Registrar without prior notice to Holders or to the Trustee.

         Subject to Section 203, upon surrender for registration of transfer of
any Security of any series at the office or agency in a Place of Payment for
that series, the Issuers shall execute, the Guarantor shall execute Guarantees
on, and the Trustee shall authenticate and deliver, in the name of the
designated transferee or transferees, one or more new Securities of the same
series, of any authorized denominations and of a like aggregate principal amount
and tenor.

         Subject to Section 203, at the option of the Holder, Securities of any
series may be exchanged for other Securities of the same series, of any
authorized denominations and of a like aggregate principal

                                      -19-

<PAGE>

amount and tenor, upon surrender of the Securities to be exchanged at such
office or agency. Whenever any Securities are so surrendered for exchange, the
Issuers shall execute, the Guarantor shall execute Guarantees on, and the
Trustee shall authenticate and deliver, the Securities which the Holder making
the exchange is entitled to receive.

         Subject to Section 203, all Securities issued upon any registration or
transfer or exchange of Securities and the Guarantees thereon shall be valid
obligations of the Issuers and the Guarantor, respectively, evidencing the same
debt, and entitled to the same benefits under this Indenture, as the Securities
surrendered upon such registration of transfer or exchange.

         Every Security presented or surrendered for registration of transfer or
for exchange shall (if so required by the Issuers or the Trustee) be duly
endorsed, or be accompanied by a written instrument of transfer in form
satisfactory to the Issuers and the Security Registrar duly executed, by the
Holder thereof or his attorney duly authorized in writing.

         No service charge shall be made for any registration of transfer or
exchange of Securities, but the Issuers may require payment of a sum sufficient
to cover any tax or other governmental charge that may be imposed in connection
with any registration of transfer or exchange of Securities, other than
exchanges pursuant to Section 203, 304, 906 or 1107 not involving any transfer.

         The Issuers shall not be required (i) to issue, register the transfer
of or exchange Securities of any series during a period beginning at the opening
of business 15 days before the day of the mailing of a notice of redemption of
Securities of that series selected for redemption (under Section 1103) and
ending at the close of business on the day of such mailing, or (ii) to register
the transfer of or exchange any Security so selected for redemption in whole or
in part, except the unredeemed portion of any Security being redeemed in part.

Section 306.      Mutilated, Destroyed, Lost and Stolen Securities.

         If there shall be delivered to the Trustee (i)(A) any mutilated
Security or (B) evidence to their satisfaction of the destruction, loss or theft
of any Security and (ii) such security or indemnity as may be required by them
to hold each of them and any agent of either of them harmless, then, in the
absence of notice to the Issuers or the Trustee that such Security has been
acquired by a bona fide purchaser, the Issuers shall execute and upon their
request the Trustee shall authenticate and deliver, in lieu of any such
destroyed, lost or stolen Security or in exchange for such mutilated Security, a
new Security of the same series and of like tenor and principal amount and
bearing a number not contemporaneously outstanding.

         In case any such mutilated, destroyed, lost or stolen Security has
become or is about to become due and payable, the Issuers in their discretion
may, instead of issuing a new Security, pay such Security.

         Upon the issuance of any new Security under this Section, the Issuers
may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in relation thereto and any other
expenses (including the fees and expenses of the Trustee) connected therewith.

                                      -20-

         Every new Security of any series issued pursuant to this Section in
lieu of any destroyed, lost or stolen Security or in exchange for such mutilated
Security, shall constitute an original additional contractual obligation of the
Issuers, whether or not the mutilated, destroyed, lost or stolen Security shall
be at any time enforceable by anyone, and shall be entitled to all the benefits
of this Indenture equally and proportionately with any and all other Securities
of that series and the Guarantee duly issued hereunder.

         The provisions of this Section are exclusive and shall preclude (to the
extent lawful) all other rights and remedies with respect to the replacement or
payment of mutilated, destroyed, lost or stolen Securities.

Section 307.      Payment of Interest; Interest Rights Preserved.

         Interest on any Security which is payable, and is punctually paid or
duly provided for, on any Interest Payment Date shall be paid to the Person in
whose name that Security (or one or more Predecessor Securities) is registered
at the close of business on the Regular Record Date for such interest.

         Any interest on any Security of any series which is payable, but is not
punctually paid or duly provided for, on any Interest Payment Date (herein
called "Defaulted Interest") shall forthwith cease to be payable to the Holder
on the relevant Regular Record Date by virtue of having been such Holder, and
such Defaulted Interest may be paid by the Issuers or the Guarantor, at their or
its election in each case, as provided in clause (1) or (2) below:

                  (1) The Issuers or the Guarantor may elect to make payment of
         any Defaulted Interest to the Persons in whose names the Securities of
         such series (or their respective Predecessor Securities) are registered
         at the close of business on a Special Record Date for the payment of
         such Defaulted Interest, which shall be fixed in the following manner.
         The Issuers or the Guarantor shall notify the Trustee in writing of the
         amount of Defaulted Interest proposed to be paid on each Security of
         such series and the date of the proposed payment, and at the same time
         the Issuers or the Guarantor shall deposit with the Trustee an amount
         of money equal to the aggregate amount proposed to be paid in respect
         of such Defaulted Interest or shall make arrangements satisfactory to
         the Trustee for such deposit prior to the date of the proposed payment,
         such money when deposited to be held in trust for the benefit of the
         Persons entitled to such Defaulted Interest as in this clause provided.
         Thereupon the Trustee shall fix a Special Record Date for the payment
         of such Defaulted Interest which shall be not more than 15 days and not
         less than 10 days prior to the date of the proposed payment and not
         less than 10 days after the receipt by the Trustee of the notice of the
         proposed payment. The Trustee shall promptly notify the Issuers and the
         Guarantor of such Special Record Date and, in the name and at the
         expense of the Issuers or the Guarantor, shall cause notice of the
         proposed payment of such Defaulted Interest and the Special Record Date
         therefor to be mailed, first-class postage prepaid, to each Holder of
         Securities of such series at his address as it appears in the Security
         Register, not less than 10 days prior to such Special Record Date.
         Notice of the proposed payment of such Defaulted Interest and the
         Special Record Date therefor having been so mailed, such Defaulted
         Interest shall be paid to the Persons in whose names the Securities of
         such series (or their respective Predecessor Securities) are registered
         at the close of business on such Special Record Date and shall no
         longer be payable pursuant to the following clause (2).

                                      -21-

<PAGE>

                  (2) The Issuers or the Guarantor may make payment of any
         Defaulted Interest on the Securities of any series in any other lawful
         manner not inconsistent with the requirements of any securities
         exchange on which such Securities may be listed, and upon such notice
         as may be required by such exchange, if, after notice given by the
         Issuers or the Guarantor to the Trustee of the proposed payment
         pursuant to this clause, such manner of payment shall be deemed
         practicable by the Trustee.

         Subject to the foregoing provisions of this Section, each Security
lawfully delivered under this Indenture upon registration of transfer of or in
exchange for or in lieu of any other Security shall carry the rights to interest
accrued and unpaid, and to accrue, which were carried by such other Security.

Section 308.      Persons Deemed Owners.

         Subject to Section 203, the Issuers, the Guarantor, the Trustee and any
agent of the Issuers, the Guarantor or the Trustee may treat the Person in whose
name such Security is registered as the owner of such Security for the purpose
of receiving payment of principal of (and premium, if any) and (subject to
Section 307) interest on such Security and for all other purposes whatsoever,
whether or not such Security be overdue, and none of the Issuers, the Guarantor,
the Trustee or any agent of the Issuers, the Guarantor or the Trustee shall be
affected by notice to the contrary.

Section 309.      Cancellation.

         All Securities surrendered for payment, redemption, registration of
transfer or exchange or for credit against any sinking fund payment shall, if
surrendered to any Person other than the Trustee, be delivered to the Trustee
and shall be promptly cancelled by it. The Issuers or the Guarantor may at any
time deliver to the Trustee for cancellation any Securities previously
authenticated and delivered hereunder which the Issuers or the Guarantor may
have acquired in any manner whatsoever, and all Securities so delivered shall be
promptly cancelled by the Trustee. No Securities shall be authenticated in lieu
of or in exchange for any Securities cancelled as provided in this Section,
except as expressly permitted by this Indenture. The Trustee shall destroy
cancelled Securities and deliver a certificate of such destruction to the
Issuers or the Guarantor.

Section 310.      Computation of Interest.

         Except as otherwise specified as contemplated by Section 301 for the
Securities of any series, interest on the Securities of each series shall be
computed on the basis of a year of 12 30-day months.

                           SATISFACTION AND DISCHARGE

Section 401.      Satisfaction and Discharge of Indenture.

as to (i) surviving rights of registration of transfer or exchange of Securities
expressly provided for, (ii) rights hereunder of Holders to receive payments of

                                      -22-

rights, obligations and immunities of the Trustee hereunder), and the Trustee,
at the expense of the Issuers or the Guarantor, shall execute proper instruments
acknowledging satisfaction and discharge of this Indenture with respect to any
series of Securities, when

         (1) either

                  (A) all Securities of such series theretofore authenticated
         and delivered (other than (i) Securities of such series which have been
         mutilated, destroyed, lost or stolen and which have been replaced or
         paid as provided in Section 306 and (ii) Securities of such series for
         whose payment money has theretofore been deposited in trust or
         segregated and held in trust by the Issuers or the Guarantor and
         thereafter repaid to the Issuers or the Guarantor or discharged from
         such trust, as provided in Section 1003) have been delivered to the
         Trustee for cancellation; or

                  (B) all such Securities not theretofore delivered to the
                      Trustee for cancellation

                      (i) have become due and payable ; or

                      (ii) will become due and payable at their Stated Maturity
                      within one year; or

                      (iii) are to be called for redemption within one year
         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 or the Guarantor,

         and the Issuers or the Guarantor in the case of (i), (ii) or (iii)
         above, have irrevocably deposited or caused to be deposited with the
         Trustee as trust funds in trust for such purpose an amount sufficient
         to pay and discharge the entire indebtedness on such Securities not
         theretofore delivered to the Trustee for cancellation, for principal of
         (and premium, if any) and interest to the date of such deposit (in the
         case of Securities which have become due and payable) or to the Stated
         Maturity or Redemption Date, as the case may be;

                  (2) if all series of Securities are being discharged, the
         Issuers or the Guarantor have paid or caused to be paid all other sums
         payable hereunder by the Issuers or the Guarantor; and

                  (3) the Issuers and the Guarantor have delivered to the
         Trustee an Officers' Certificate and an Opinion of Counsel, each
         stating that all conditions precedent herein provided for relating to
         the satisfaction and discharge of this Indenture have been satisfied.

         Notwithstanding the satisfaction and discharge of this Indenture, the
obligations of the Issuers and the Guarantor to the Trustee under Section 607
and, if money shall have been deposited with the

                                      -23-

<PAGE>

Trustee pursuant to subclause (B) of clause (1) of this Section, the obligations
of the Trustee under Section 402 and the next to last paragraph of Section 1003
shall survive any such satisfaction and discharge.

Section 402.      Application of Trust Funds; Indemnification.

         (a) Subject to the provisions of the next to last paragraph of Section
1003, all money deposited with the Trustee pursuant to Section 401, all money

403 or 404 and all money received by the Trustee in respect of U.S. Government
Obligations deposited with the Trustee pursuant to Section 403 or 404 shall be
held in trust and applied by it, in accordance with the provisions of the
Securities and this Indenture, to the payment, either directly or through any
Paying Agent (including the Issuers or the Guarantor acting as Paying Agent) as
the Trustee may determine, to the Persons entitled thereto, of the principal
(and premium, if any) and interest for whose payment such money has been
deposited with or received by the Trustee or to make mandatory sinking fund
payments or analogous payments as contemplated by Section 403 or 404, but such
money need not be segregated from other funds except to the extent required by
law.

         (b) The Issuers or the Guarantor shall pay and shall indemnify the
Trustee against any tax, fee or other charge imposed on or assessed against U.S.
Government Obligations deposited pursuant to Section 403 or 404, or the interest
and principal received in respect of such obligations other than any payable by

         (c) The Trustee shall deliver or pay to the Issuers or the Guarantor
from time to time upon Issuers Request or Guarantor Request any U.S. Government
Obligations or money held by it as provided in Section 403 or 404 which, in the
opinion of a nationally recognized firm of independent public accountants
expressed in a written certification thereof delivered to the Trustee, are then
in excess of the amount thereof which then would have been required to be
deposited for the purpose for which such obligations or money were deposited or
received.

Section 403.      Defeasance and Discharge of Indenture.

         The Issuers and the Guarantor shall be deemed to have paid and
discharged the entire indebtedness on all the Outstanding Securities on the 91st
day after the date of the deposit referred to in subparagraph (d) of this
Section, and the provisions of this Indenture, as it relates to such Outstanding
Securities, shall no longer be in effect (and the Trustee, at the expense of the
Issuers or the Guarantor, shall at Issuers Request or Guarantor Request, execute
proper instruments acknowledging the same), except as to:

         (a) the rights of Holders of Securities to receive, from the trust
funds described in subparagraph (d) hereof, (i) payment of the principal of (and
premium, if any) and each installment of principal of (and premium, if any) or
interest on the Outstanding Securities on the Stated Maturity of such principal
or installment of principal or interest and (ii) the benefit of any mandatory
sinking fund payments applicable to the Securities on the day on which such
payments are due and payable in accordance with the terms of this Indenture and
the Securities;

         (b) the Issuers' and the Guarantor's obligations with respect to such
Securities under Sections 305, 306, 1002 and 1003; and

                                      -24-

<PAGE>

         (c) the obligations of the Issuers and the Guarantor to the Trustee
under Section 607,

provided that, the following conditions shall have been satisfied:

                  (1) the Issuers or the Guarantor have or caused to be
         irrevocably deposited (except as provided in Section 402) with the
         Trustee as trust funds in trust, specifically pledged as security for,
         and dedicated solely to, the benefit of the Holders of the Securities,
         (i) money in an amount, or (ii) U.S. Government Obligations which
         through the payment of interest and principal in respect thereof in
         accordance with their terms will provide not later than one day before
         the due date of any payment referred to in clause (A) or (B) of this
         subparagraph money in an amount, or (iii) a combination thereof,
         sufficient, in the opinion of a nationally recognized firm of
         independent certified public accountants expressed in a written
         certification thereof delivered to the Trustee, to pay and discharge
         (A) the principal of (and premium, if any) and each installment of
         principal of (and premium, if any) and interest on the Outstanding
         Securities on the Stated Maturity of such principal or installment of
         principal or interest or on the applicable Redemption Date and (B) any
         mandatory sinking fund payments applicable to the Securities on the day
         on which such payments are due and payable in accordance with the terms
         of this Indenture and of the Securities;

                  (2) such deposit shall not cause the Trustee with respect to
         the Securities to have a conflicting interest for purposes of the Trust
         Indenture Act with respect to the Securities;

                  (3) such deposit will not result in a breach or violation of,
         or constitute a default under, any applicable laws, this Indenture or
         any other agreement or instrument to which the Issuers or the Guarantor
         are a party or by which they are bound;

                  (4) no Event of Default or event which with notice or lapse of
         time would become an Event of Default with respect to the Securities
         shall have occurred and be continuing on the date of such deposit or
         during the period ending on the 91st day after such date;

                  (5) if the deposit referred to in subparagraph (d) of this
         Section is to be made on or prior to one year from the Stated Maturity
         for payment of principal of the Outstanding Securities, the Issuers and
         the Guarantor have delivered to the Trustee an Opinion of Counsel with
         no material qualifications or a favorable ruling of the Internal
         Revenue Service, in either case to the effect that Holders of the
         Securities will not recognize income, gain or loss for federal income
         tax purposes as a result of such deposit, defeasance and discharge and
         will be subject to federal income tax on the same amount and in the
         same manner and at the same times, as would have been the case if such
         deposit, defeasance and discharge had not occurred.

Section 404.      Defeasance of Certain Obligations.

         If this Section is specified to be applicable to Securities of any
series, the Issuers or the Guarantor may omit to comply with (or elect to have
the obligations of the Guarantor released with respect to) any term, provision
or condition set forth in the Sections of this Indenture or such Security with
respect to the Securities of that series ("Covenant Defeasance") if:

                                      -25-

<PAGE>

                  (1) with reference to this Section, the Issuers or the
         Guarantor have deposited or caused to be irrevocably deposited with the
         Trustee as trust funds in trust, specifically pledged as security for,
         and dedicated solely to, the benefit of the Holders of the Securities
         of that series, (i) money in an amount, or (ii) U.S. Government
         Obligations which through the payment of interest and principal in
         respect thereof in accordance with their terms will provide not later
         than one day before the due date of any payment referred to in clause
         (A) or (B) of this subparagraph money in an amount, or (iii) a
         combination thereof, sufficient, in the opinion of a nationally
         recognized firm of independent public accountants expressed in a
         written certification thereof delivered to the Trustee, to pay and
         discharge (A) the principal of (and premium, if any) and each
         installment of principal (and premium, if any) and interest on the
         Outstanding Securities of that series on the Stated Maturity of such
         principal or installment of principal or interest and (B) any mandatory
         sinking fund payments or analogous payments applicable to Securities of
         such series on the day on which such payments are due and payable in
         accordance with the terms of the Indenture and of such Securities;

                  (2) such deposit shall not cause the Trustee with respect to
         the Securities of that series to have a conflicting interest for
         purposes of the Trust Indenture Act with respect to the Securities of
         any series;

                  (3) such deposit will not result in a breach or violation of,
         or constitute a default under, this Indenture or any other agreement or
         instrument to which the Issuers or the Guarantor are parties or a party
         or by which they or it are bound;

                  (4) if the deposit referred to in subparagraph (1) of this
         Section is to be made on or prior to one year from the Stated Maturity
         for payment of principal of the Outstanding Securities, the Issuers and
         the Guarantor have delivered to the Trustee an Opinion of Counsel with
         no material qualifications or a favorable ruling of the Internal
         Revenue Service, in either case to the effect that Holders of the
         Securities will not recognize income, gain or loss for federal income
         tax purposes as a result of such deposit and defeasance of certain
         obligations and will be subject to federal income tax on the same
         amount and in the same manner and at the same times, as would have been
         the case if such deposit and defeasance had not occurred; and

                  (5) the Issuers and the Guarantor have delivered to the
         Trustee an Officers' Certificate and an Opinion of Counsel, each
         stating that all conditions precedent herein provided for relating to
         the defeasance contemplated by this Section have been complied with.

         In the event the Issuers or the Guarantor effect Covenant Defeasance
with respect to any Securities and such Securities are declared due and payable
because of the occurrence of any Event of Default, other than an Event of
Default with respect to any covenant as to which there has been Covenant
Defeasance, the U.S. Government Obligations on deposit with the Trustee will be
sufficient to pay amounts due on such Securities at the time of the Stated
Maturity but may not be sufficient to pay amounts due on such Securities at the
time of the acceleration resulting from such Event of Default.

         creditors, or the admission by it in writing of its inability to pay
         its debts generally as they become due and its willingness to have a
         case commenced against it or to seek an order for relief under any
         applicable bankruptcy, insolvency or other similar law or the taking of
         corporate action by either of the Issuers or the Guarantor in
         furtherance of any such action;

                  (6) the Guarantee ceases to be in full force and effect or is
         declared to be null and void and unenforceable or is found to be
         invalid, in each case by a court of competent jurisdiction in a final
         non-appealable judgment, or the Guarantor denies its liability under
         the Guarantee (other than by reason of release of the Guarantor in
         accordance with the terms of this Indenture); or

                  (7) any other Event of Default expressly provided with respect
         to Securities of that series.

Section 502.      Acceleration of Maturity; Rescission and Annulment.

         If an Event of Default (other than by reason of an Event of Default
specified in clause (4) or (5) of Section 501) with respect to Securities of any
series at the time Outstanding occurs and is continuing, then in every such case
the Trustee or the Holders of not less than 25% in principal amount of the
Outstanding Securities of that series may declare the unpaid principal of and
accrued interest to the date of acceleration on (or, if the Securities of that
series are Original Issue Discount Securities, such portion of the principal
amount as may be specified in the terms of that series) all of the Securities of
that series to be due and payable immediately, by a notice in writing to the
Issuers and the Guarantor (and to the Trustee if given by Holders), and upon any
such declaration, such unpaid principal and accrued interest (or specified
principal amount) shall become immediately due and payable.

         If an Event of Default specified in clause (4) or (5) of Section 501
with respect to Securities of any series at the time Outstanding occurs and is
continuing, then all unpaid principal of and accrued interest on the Outstanding
Securities of that series (or specified principal amount) shall become
immediately due and payable without any notice or other action on the part of
the Trustee or the Holders of the Securities of such series.

         At any time after such a declaration of acceleration with respect to
Securities of any series has been made and before a judgment or decree for
payment of the money due has been obtained by the Trustee as hereinafter in this
Article provided, the Holders of a majority in principal amount of the
Outstanding Securities of that series, by written notice to the Issuers, the
Guarantor and the Trustee, may rescind and annul such declaration and its
consequences if

                  (1) the Issuers or the Guarantor have paid or deposited with
         the Trustee a sum sufficient to pay

                           (A) all overdue interest on all Securities of that
                  series,

                                      -28-

<PAGE>

                           (B) the principal of (and premium, if any, on) any
                    Securities of that series which have become due otherwise
                    than by such declaration of acceleration and interest
                    thereon at the rate or rates prescribed therefor in such
                    Securities,

                           (C) to the extent that payment of such interest is
                    lawful, interest upon overdue interest at the rate or rates
                    prescribed therefor in such Securities, and

                           (D) all sums paid or advanced by the Trustee and any
                    predecessor Trustee hereunder and all sums due the Trustee
                    and any predecessor Trustee under Section 607;

                and

                  (2) all Events of Default with respect to Securities of that
         series, other than the non-payment of the principal of Securities of
         that series which have become due solely by such declaration of
         acceleration, have been cured or waived as provided in Section 513.

         No such rescission shall affect any subsequent default or impair any
right consequent thereon.

Section 503.      Collection of Indebtedness and Suits for Enforcement
                  by Trustee.

         The Issuers and the Guarantor covenant that if

                  (1) default is made in the payment of any interest on any
         Security when such interest becomes due and payable and such default
         continues for a period of 30 days, or

                  (2) default is made in the payment of the principal of (or
         premium, if any, on) any Security at the Maturity thereof,

the Issuers or the Guarantor will, upon demand of the Trustee, pay to it, for
the benefit of the Holders of such Securities, the whole amount then due and
payable on such Securities for principal (and premium, if any) and interest and,
to the extent that payment of such interest shall be legally enforceable,
interest on any overdue principal (and premium, if any) and on any overdue
interest, at the rate or rates prescribed therefor in such Securities, and, in
addition thereto, such further amount as shall be sufficient to cover the costs
and expenses of collection, including all amounts due the Trustee and any
predecessor Trustee under Section 607.

         If the Issuers or the Guarantor fail to pay such amounts forthwith upon
such demand, the Trustee, in its own name and as trustee of an express trust,
may institute a judicial proceeding for the collection of the sums so due and
unpaid, may prosecute such proceeding to judgment or final decree and may
enforce the same against the Issuers or the Guarantor or any other obligor upon
such Securities and collect the moneys adjudged or decreed to be payable in the
manner provided by law out of the property of the Issuers or the Guarantor or
any other obligor upon such Securities, wherever situated.

                                      -29-

<PAGE>

         If any Event of Default with respect to Securities of any series occurs
and is continuing, the Trustee may in its discretion proceed to protect and
enforce its rights and the rights of the Holders of Securities of such series by
such appropriate judicial proceedings as the Trustee shall deem most effectual
to protect and enforce any such rights, whether for the specific enforcement of
any covenant or agreement in this Indenture or in aid of the exercise of any
power granted herein, or to enforce any other proper remedy.

Section 504.      Trustee May File Proofs of Claim.

         In case of the pendency of any receivership, insolvency, liquidation,
bankruptcy, reorganization, arrangement, adjustment, composition or other
judicial proceeding relative to either of the Issuers or the Guarantor or any
other obligor, upon the Securities or the property of either of the Issuers or
the Guarantor or of such other obligor or their creditors, the Trustee
(irrespective of whether the principal of the Securities shall then be due and
payable as therein expressed or by declaration or otherwise and irrespective of
whether the Trustee shall have made any demand on the Issuers or the Guarantor
for the payment of overdue principal, premium, if any, or interest) shall be
entitled and empowered, by intervention in such proceeding or otherwise, to file
and prove a claim for the whole amount of principal (and premium, if any),
interest owing and unpaid in respect of the Securities and to file such other
papers or documents as

                  (1) may deem 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 of the Holders allowed in such judicial
         proceeding, and

                  (2) to collect and receive any moneys or other property
         payable or deliverable on any such claims and to distribute the same;

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or
other similar official 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 the Trustee any amount due 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 607.

         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 Securities
or the rights of any Holder thereof, or to authorize the Trustee to vote in
respect of the claim of any Holder in any such proceeding.

Section 505.      Trustee May Enforce Claims Without Possession of Securities.

         All rights of action and claims under this Indenture or the Securities
may be prosecuted and enforced by the Trustee without the possession of any of
the Securities or the production thereof in any proceeding relating thereto, and
any such proceeding instituted by the Trustee shall be brought in its own name
and as trustee of an express trust, and any recovery of judgment shall, after
provision for the payment of the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents

                                      -30-

<PAGE>

and counsel, be for the ratable benefit of the Holders of the Securities in
respect of which such judgment has been recovered.

Section 506.      Application of Money Collected.

         Any money collected by the Trustee pursuant to this Article shall be
applied in the following order, at the date or dates fixed by the Trustee and,
in case of the distribution of such money on account of principal (or premium,
if any) or interest, upon presentation of the Securities and the notation
thereon of the payment if only partially paid and upon surrender thereof if
fully paid:

                  FIRST: To the payment of all amounts due the Trustee and each
         predecessor Trustee under Section 607;

                  SECOND: To the payment of the amounts then due and unpaid for
         principal of (and premium, if any) and interest on the Securities in
         respect of which or for the benefit of which such money has been
         collected, ratably, without preference or priority of any kind,
         according to the amounts due and payable on such Securities for
         principal (and premium, if any), and interest, respectively; and

                  THIRD:  To the Issuers.

Section 507.      Limitation on Suits.

         No Holder of any Security of any series shall have any right to
institute any proceeding, judicial or otherwise, with respect to this Indenture,
or for the appointment of a receiver or trustee, or for any other remedy
hereunder, unless:

                  (1) such Holder has previously given written notice to the
         Trustee of a continuing Event of Default with respect to the Securities
         of that series;

                  (2) the Holders of not less than 25% in principal amount of
         the Outstanding Securities of that series shall have made written
         request to the Trustee to institute proceedings in respect of such
         Event of Default in its own name as Trustee hereunder;

                  (3) such Holder or Holders have offered to the Trustee
         reasonable indemnity against the costs, expenses and liabilities to be
         incurred in compliance with such request;

                  (4) the Trustee for 60 days after its receipt of such notice,
         request and offer of indemnity has failed to institute any such
         proceeding; and

                  (5) no direction inconsistent with such written request has
         been given to the Trustee during such 60-day period by the Holders of a
         majority in principal amount of the Outstanding Securities of that
         series;

                                      -31-

<PAGE>

it being understood and intended that no one or more of such Holders shall have
any right in any manner whatever by virtue of, or by availing of, any provision
of this Indenture to affect, disturb or prejudice the rights of any other of
such Holders, or to obtain or to seek to obtain priority or preference over any
other of such Holders or to enforce any right under this Indenture, except in
the manner herein provided and for the equal and ratable benefit of all such
Holders.

Section 508.      Unconditional Right of Holders to Receive Principal, Premium
                  and Interest.

         Notwithstanding any other provision in this Indenture, the Holder of
any Security shall have the right, which is absolute and unconditional, to
receive payment of the principal of (and premium, if any) and (subject to
Section 307) interest on such Security or the Guarantee on the Stated Maturity
or Maturities expressed in such Security (or, in the case of redemption, on the
Redemption Date) and to institute suit for the enforcement of any such payment,
and such rights shall not be impaired without the consent of such Holder.

Section 509.      Restoration of Rights and Remedies.

         If the Trustee or any Holder has instituted any proceeding to enforce
any right or remedy under this Indenture or the Guarantee and such proceeding
has been discontinued or abandoned for any reason, or has been determined
adversely to the Trustee or to such Holder, then and in every such case, subject
to any determination in such proceeding, the Issuers, the Guarantor, the Trustee
and the Holders shall be restored severally and respectively to their former
positions hereunder and thereafter all rights and remedies of the Trustee and
the Holders shall continue as though no such proceeding had been instituted.

Section 510.      Rights and Remedies Cumulative.

         Except as otherwise provided with respect to the replacement or payment
of mutilated, destroyed, lost or stolen Securities in the last paragraph of
Section 306, no right or remedy herein or in the Guarantee conferred upon or
reserved to the Trustee or to the Holders is intended to be exclusive of any
other right or remedy, and every right and remedy shall, to the extent permitted
by law, be cumulative and in addition to every other right and remedy given
hereunder or now or hereafter existing at law or in equity or otherwise. The
assertion or employment of any right or remedy hereunder, or otherwise, shall
not prevent the concurrent assertion or employment of any other appropriate
right or remedy.

Section 511.      Delay or Omission Not Waiver.

         No delay or omission of the Trustee or of any Holder of any Securities
to exercise any right or remedy accruing upon any Event of Default shall impair
any such right or remedy or constitute a waiver of any such Event of Default or
any acquiescence therein. Every right and remedy given by this Article or by law
to the Trustee or to the Holders may be exercised from time to time, and as
often as may be deemed expedient, by the Trustee or by the Holders, as the case
may be.

                                      -32-

Section 512.      Control by Holders.

         The Holders of a majority in principal amount of the Outstanding
Securities of any series (or if more than one series is affected thereby, of all
series so affected, voting as a single class) shall have the right to direct the
time, method and place of conducting any proceeding for any remedy available to
the Trustee, or exercising any trust or power conferred on the Trustee, with
respect to the Securities of such series, provided that

                  (1) such direction shall not be in conflict with any rule of
         law or with this Indenture, expose the Trustee to personal liability or
         be unduly prejudicial to holders not joining therein, and

                  (2) the Trustee may take any other action deemed proper by the
         Trustee which is not inconsistent with such direction.

         Nothing in this Indenture shall impair the right of the Trustee to take
any other action deemed proper by the Trustee which is not inconsistent with
such direction.

Section 513.      Waiver of Past Defaults.

         The Holders of not less than a majority in principal amount of the
Outstanding Securities of any series may on behalf of the Holders of all the
Securities of such series waive any past default hereunder with respect to such
series and its consequences, except a default

                  (1) in the payment of the principal of (or premium, if any) or
         interest on any Security of such series, or

                  (2) in respect of a covenant or provision hereof which under
         this Article cannot be modified or amended without the consent of the
         Holder of each Outstanding Security of such series affected.

         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 514.      Undertaking for Costs.

         All parties to this Indenture agree, and each Holder of any Security by
his acceptance thereof shall be deemed to have agreed, that any court may in its
discretion require, 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,
suffered or omitted by it as Trustee, the filing by any party litigant in such
suit of an undertaking to pay the costs of such suit, and that such court may in
its discretion assess reasonable costs, including reasonable attorneys' fees,
against any party litigant in such suit, having due regard to the merits and
good faith of the claims or defenses made by such party litigant; but the
provisions of this Section shall not apply to any suit instituted by the
Issuers, to any suit instituted by the Trustee, to any suit instituted by any
Holder, or group of Holders, holding in the aggregate more than 10% in principal
amount of the

                                      -33-

<PAGE>

Outstanding Securities of any series, or to any suit instituted by
any Holder for the enforcement of the payment of the principal of (or premium,
if any) or interest on any Securities on or after the Stated Maturity or
Maturities expressed in such Security (or, in the case of redemption, on or
after the Redemption Date). This Section 514 shall be in lieu of Section 315(e)
of the Trust Indenture Act and such Section 315(e) is hereby expressly excluded
from this Indenture, as permitted by the Trust Indenture Act.

                                   Article Six
                                   THE TRUSTEE

Section 601.      Certain Duties and Responsibilities.

         (a) Except during the continuance of an Event of Default with respect
to the Securities of any series,

                  (1) the Trustee undertakes to perform such duties and only
         such duties as are specifically set forth in this Indenture with
         respect to such series, and no implied covenants or obligations shall
         be read into this Indenture against the Trustee; and

                  (2) in the absence of bad faith on its part, the Trustee may
         conclusively rely, as to the truth of the statements and the
         correctness of the opinions expressed therein, upon certificates or
         opinions furnished to the Trustee and conforming to the requirements of
         this Indenture; but in the case of any such certificates or opinions
         which by any provision hereof are specifically required to be furnished
         to the Trustee, the Trustee shall be under a duty to examine the same
         to determine whether or not they conform to the requirements of this
         Indenture.

         (b) In case an Event of Default has occurred with respect to Securities
of any series and is continuing, the Trustee shall exercise such of the rights
and powers vested in it by this Indenture with respect to such series of
Securities, and use the same degree of care and skill in their exercise, as a
prudent man would exercise or use under the circumstances in the conduct of his
own affairs.

         (c) No provision of this Indenture shall be construed to relieve the
Trustee from liability for its own negligent action, its own negligent failure
to act, or its own willful misconduct, except that

                  (1) this Subsection shall not be construed to limit the effect
         of Subsection (a) of this Section;

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

                  (3) the Trustee shall not be liable with respect to any action
         taken or omitted to be taken by it in good faith in accordance with the
         direction of the Holders of a majority in principal amount of the
         Outstanding Securities of any series, determined as provided in Section
         512, relating to the time, method and place of conducting any
         proceeding for any remedy available to the

                                      -34-

<PAGE>

         Trustee, or exercising any trust or power conferred upon the Trustee,
         under this Indenture with respect to the Securities of such series; and

                  (4) no provision of this Indenture shall require the Trustee
         to expend or risk its own funds or otherwise incur any financial
         liability in the performance of any of its duties hereunder, or in the
         exercise of any of its rights or powers, if it shall have reasonable
         grounds for believing that repayment of such funds or adequate
         indemnity against such risk or liability is not reasonably assured to
         it.

         (d) Whether or not therein expressly so provided, every provision of
this Indenture relating to the conduct or affecting the liability of or
affording protection to the Trustee shall be subject to the provisions of this
Section and to the Trust Indenture Act.

Section 602.      Notice of Defaults.

         Within 90 days after the occurrence of any default hereunder with
respect to the Securities of any series, the Trustee shall transmit by mail to
all Holders of Securities of such series, as their names and addresses appear in
the Security Register, notice of such default hereunder known to the Trustee,
unless such default shall have been cured or waived; provided, however, that,
except in the case of a default in the payment of the principal of (or premium,
if any) or interest on any Security of such series or in the payment of any
sinking fund installment with respect to Securities of such series, the Trustee
shall be protected in withholding such notice if and so long as the board of
directors, the executive committee or a trust committee of directors or
Responsible Officers of the Trustee in good faith determines that the
withholding of such notice is in the interest of the Holders of Securities of
such series; and provided, further, that in the case of any default of the
character specified in Section 501(3) with respect to Securities of such series,
no such notice to Holders shall be given until at least 30 days after the
occurrence thereof. For the purpose of this Section, the term "default" means
any event which is, or after notice or lapse of time or both would become, an
Event of Default with respect to Securities of such series.

Section 603.      Certain Rights of Trustee.

         Subject to the provisions of Section 601:

         (a) the Trustee may rely and shall be protected in acting or refraining
from acting upon any Committee Resolution, Board Resolution, resolution,
Officers' Certificate, certificate, statement, instrument, Opinion of Counsel,
opinion, report, notice, request, direction, consent, order, bond, debenture,
note, other evidence of indebtedness or other paper or document believed by it
to be genuine and to have been signed or presented by the proper party or
parties;

Resolution or a Board Resolution;

                                      -35-

<PAGE>

         (c) whenever in the administration of this Indenture the Trustee shall
deem it desirable that a matter be proved or established prior to taking,
suffering or omitting any action hereunder, the Trustee (unless other evidence
be herein specifically prescribed) may, in the absence of bad faith on its part,
rely upon an Officers' Certificate;

         (d) the Trustee may consult with counsel and the advice of such counsel
or any Opinion of Counsel shall be full and complete authorization and
protection in respect of any action taken, suffered or omitted by it hereunder
in good faith and in reliance thereon;

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

         (f) the Trustee shall not be bound to make any investigation into the
facts or matters stated in any resolution, certificate, statement, instrument,
opinion, report, notice, request, direction, consent, order, bond, debenture,
note, other evidence of indebtedness or other paper or document, but the
Trustee, in its discretion, may make such further inquiry or investigation into
such facts or matters as it may see fit, and, if the Trustee shall determine to
make such further inquiry or investigation, it shall be entitled to examine the
books, records and premises of the Issuers, personally or by agent or attorney;
and

         (g) the Trustee may execute any of the trusts or powers hereunder or
perform any duties hereunder either directly or by or through agents or
attorneys and the Trustee shall not be responsible for any misconduct or
negligence on the part of any agent or attorney appointed with due care by it
hereunder.

Section 604.      Trustee Not Responsible for Recitals or Issuance of
                  Securities.

         The recitals contained herein and in the Securities, except the
Trustee's certificates of authentication, shall be taken as the statements of
the Issuers, and the Trustee assumes no responsibility for their correctness.
The Trustee makes no representations as to the validity or sufficiency of this
Indenture or of the Securities. The Trustee shall not be accountable for the use
or application by the Issuers of Securities or the proceeds thereof.

Section 605.      May Hold Securities.

         The Trustee, any Paying Agent, any Security Registrar or any other
agent of the Issuers or the Guarantor, in its individual or any other capacity,
may become the owner or pledgee of Securities and, subject to Sections 608 and

Section 606.      Money Held in Trust.

         Money held by the Trustee in trust hereunder need not be segregated

under no liability for interest on any money received by it hereunder except as
otherwise agreed with the Issuers and the Guarantor.

Section 607.      Compensation and Reimbursement.

         The Issuers and the Guarantor, jointly and severally, agree:

                  (1) to pay to the Trustee from time to time reasonable
         compensation for all services rendered by it hereunder (which
         compensation shall not be limited by any provision of law in regard to
         the compensation of a trustee of an express trust);

                  (2) except as otherwise expressly provided herein, to
         reimburse each of the Trustee and any predecessor Trustee upon its
         request for all reasonable expenses, disbursements and advances
         incurred or made by it in accordance with any provision of this
         Indenture (including the reasonable compensation and the expenses and
         disbursements of its agents and counsel), except any such expense,
         disbursement or advance as may be attributable to its own negligence or
         bad faith; and

                  (3) to indemnify each of the Trustee and any predecessor
         Trustee for, and to hold it harmless against, any loss, liability or
         expense, arising out of or in connection with the acceptance or
         administration of the trust or trusts hereunder and the performance of
         its duties hereunder, including the costs and expenses of defending
         itself against any claim or liability in connection with the exercise
         or performance of any of its powers or duties hereunder, except to the
         extent any such loss, liability or expense is due to its own negligence
         or bad faith.

         To ensure the performance of the obligations of the Issuers or the
Guarantor under this Section, the Trustee shall have a senior claim to which the
Securities are hereby made subordinate upon all property and funds held or
collected by the Trustee as such, except property and funds held in trust for
the payment of principal of, premium, if any, or interest on particular
Securities.

Section 608.      Disqualification; Conflicting Interests.

         Trustee shall comply with the terms of Section 310(b) of the Trust
Indenture Act. The provisions of Section 310 of the Trust Indenture Act shall
apply to the Issuers and the Guarantor as obligors of the Securities.

Section 609.      Corporate Trustee Required; Eligibility.

         There shall at all times be a Trustee hereunder which shall be a
corporation organized and doing business under the laws of the United States of
America, any State thereof or the District of Columbia, authorized under such
laws to exercise corporate trust powers having (or, in the case of the
subsidiary of a bank holding company that guarantees the obligations of the
Trustee under this Indenture, such holding

                                      -37-

<PAGE>

company's parent shall have) a combined capital and surplus of at least
$50,000,000 subject to supervision or examination by Federal or State authority.
If such corporation or holding company parent publishes reports of condition at
least annually, pursuant to law or the requirements of said supervising or
examining authority, then for the purposes of this Section, the combined capital
and surplus of such corporation or holding company parent shall be deemed to be
its combined capital and surplus as set forth in its most recent report of
condition so published. If at any time the Trustee shall cease to be eligible in
accordance with the provisions of this Section, it shall resign immediately in
the manner and with the effect hereinafter specified in this Article.

Section 610.      Resignation and Removal; Appointment of Successor.

         (a) No resignation or removal of the Trustee and no appointment of a
successor Trustee pursuant to this Article shall become effective until the
acceptance of appointment by the successor Trustee in accordance with the
applicable requirements of Section 611.

         (b) The Trustee may resign at any time with respect to the Securities
of one or more series by giving written notice thereof to the Issuers and the
Guarantor. If the instrument of acceptance by a successor Trustee required by
Section 611 shall not have been delivered to the Trustee within 30 days after
the giving of such notice of resignation, the resigning Trustee may petition any
court of competent jurisdiction for the appointment of a successor Trustee with
respect to the Securities of such series. If the acceptance of appointment is
substantially contemporaneous with the resignation, then the notice called for
by the first sentence of this Subsection may be combined with the instrument
called for by Section 611.

         (c) the Trustee may be removed at any time with respect to the
Securities of any series by Act of the Holders of a majority in principal amount
of the Outstanding Securities of such series delivered to the Trustee, the
Issuers and the Guarantor.

         (d) If at any time:

                  (1) the Trustee shall fail to comply with Section 608 after
         written request therefor by the Issuers, the Guarantor or by any Holder
         who has been a bona fide Holder of a Security for at least six months,
         or

                  (2) the Trustee shall cease to be eligible under Section 609
         and shall fail to resign after written request therefor by the Issuers,
         the Guarantor or by any such Holder, or

                  (3) the Trustee shall become incapable of acting or shall be
         adjudged a bankrupt or insolvent or a receiver of the Trustee or of its
         property shall be appointed or any public officer shall take charge or
         control of the Trustee or of its property or affairs for the purpose of
         rehabilitation, conservation or liquidation,

then, in any such case, (i) the Issuers or the Guarantor by a Committee
Resolution or a Board Resolution, as the case may be, may remove the Trustee
with respect to all Securities, or (ii) subject to Section 514, any Holder who
has been a bona fide Holder of a Security for at least six months may, on behalf
of himself

                                      -38-

<PAGE>

and all others similarly situated, petition any court of competent
jurisdiction for the removal of the Trustee with respect to all Securities and
the appointment of a successor Trustee or Trustees.

         (e) If the Trustee shall resign, be removed or become incapable of
acting, or if a vacancy shall occur in the office of Trustee for any cause, with
respect to the Securities of one or more series, the Issuers or the Guarantor,
by a Committee Resolution or a Board Resolution, as the case may be, shall
promptly appoint a successor Trustee or Trustees with respect to the Securities
of that or those series (it being understood that any such successor Trustee may
be appointed with respect to the Securities of one or more or all of such series
and that at any time there shall be only one Trustee with respect to the
Securities of any particular series) and shall comply with the applicable
requirements of Section 611. If, within one year after such resignation, removal
or incapability, or the occurrence of such vacancy, a successor Trustee with
respect to the Securities of any series shall be appointed by Act of the Holders
of a majority in principal amount of the Outstanding Securities of such series
delivered to the Issuers, the Guarantor and the retiring Trustee, the successor
Trustee so appointed shall, forthwith upon its acceptance of such appointment in
accordance with the applicable requirements of Section 611, become the successor
Trustee with respect to the Securities of such series and to that extent
supersede the successor appointed by the Issuers or the Guarantor. If no
successor Trustee with respect to the Securities of any series shall have been
so appointed by the Issuers, the Guarantor or the Holders and accepted
appointment in the manner required by Section 611, any Holder who has been a
bona fide Holder of a Security of such series for at least six months may, on
behalf of himself and all others similarly situated, petition any court of
competent jurisdiction for the appointment of a successor Trustee with respect
to the Securities of such series.

         (f) The Issuers or the Guarantor shall give notice of each resignation
and each removal of the Trustee with respect to the Securities of any series and
each appointment of a successor Trustee with respect to the Securities of any
series by mailing written notice of such event by first-class mail, postage
prepaid, to all Holders of Securities of such series as their names and
addresses appear in the Security Register. Each notice shall include the name of
the successor Trustee with respect to the Securities of such series and the
address of its Corporate Trust Office.

Section 611.      Acceptance of Appointment by Successor.

         (a) In case of the appointment hereunder of a successor Trustee with
respect to all Securities, every such successor Trustee so appointed shall
execute, acknowledge and deliver to the Issuers, the Guarantor and to the
retiring Trustee an instrument accepting such appointment, and thereupon the
resignation or removal of the retiring Trustee shall become effective and such
successor Trustee, without any further act, deed or conveyance, shall become
vested with all the rights, powers, trusts and duties of the retiring Trustee;
but, on the request of the Issuers, the Guarantor or the successor Trustee, such
retiring Trustee shall, upon payment of its charges, execute and deliver an
instrument transferring to such successor Trustee all the rights, powers and
trusts of the retiring Trustee and shall duly assign, transfer and deliver to
such successor Trustee all property and money held by such retiring Trustee
hereunder.

         (b) In case of the appointment hereunder of a successor Trustee with
respect to the Securities of one or more (but not all) series, the Issuers, the
Guarantor, the retiring Trustee and each successor Trustee with respect to the
Securities of one or more series shall execute and deliver an indenture
supplemental

                                      -39-

<PAGE>

hereto wherein each successor Trustee shall accept such appointment and which
(1) shall contain such provisions as shall be necessary or desirable to transfer
and confirm to, and to vest in, each successor Trustee all the rights, powers,
trusts and duties of the retiring Trustee with respect to the Securities of that
or those series to which the appointment of such successor Trustee relates, (2)
if the retiring Trustee is not retiring with respect to all Securities, shall
contain such provisions as shall be deemed necessary or desirable to confirm
that all the rights, powers, trusts and duties of the retiring Trustee with
respect to the Securities of that or those series as to which the retiring
Trustee is not retiring shall continue to be vested in the retiring Trustee, and
(3) shall add to or change any of the provisions of this Indenture as shall be
necessary to provide for or facilitate the administration of the trusts
hereunder by more than one Trustee, it being understood that nothing herein or
in such supplemental indenture shall constitute such Trustees co-trustees of the
same trust and that each such Trustee shall be trustee of a trust or trusts
hereunder separate and apart from any trust or trusts hereunder administered by
any other such Trustee; and upon the execution and delivery of such supplemental
indenture the resignation or removal of the retiring Trustee shall become
effective to the extent provided therein and each such successor Trustee,
without any further act, deed or conveyance, shall become vested with all the
rights, powers, trusts and duties of the retiring Trustee with respect to the
Securities of that or those series to which the appointment of such successor
Trustee relates; but, on request of the Issuers, the Guarantor or any successor
Trustee, such retiring Trustee shall duly assign, transfer and deliver to such
successor Trustee all property and money held by such retiring Trustee hereunder
with respect to the Securities of that or those series to which the appointment
of such successor Trustee relates.

         (c) Upon request of any such successor Trustee, the Issuers and the
Guarantor shall execute any and all instruments for more fully and certainly
vesting in and confirming to such successor Trustee all such rights, powers and
trusts referred to in paragraph (a) or (b) of this Section, as the case may be.

         (d) No successor Trustee shall accept its appointment unless at the
time of such acceptance such successor Trustee shall be qualified and eligible
under this Article.

Section 612.      Merger, Conversion, Consolidation or Succession to Business.

         Any corporation into which the Trustee may be merged or converted or
with which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any
corporation succeeding to all or substantially all the corporate trust business
of the Trustee (including the administration of this Indenture), shall be the
successor of the Trustee hereunder, provided such corporation shall be otherwise
qualified and eligible under this Article, without the execution or filing of
any paper or any further act on the part of any of the parties hereto. In case
any Securities shall have been authenticated, but not delivered, by the Trustee
then in office, any successor by merger, conversion or consolidation to such
authenticating Trustee may adopt such authentication and deliver the Securities
so authenticated with the same effect as if such successor Trustee had itself
authenticated such Securities.

Section 613.      Preferential Collection of Claims Against Issuers.

         If and when the Trustee shall be or become a creditor of the Issuers or
the Guarantor (or any other obligor upon the Securities), the Trustee shall be
subject to the provisions of the Trust Indenture

                                      -40-

<PAGE>

Act regarding the collection of claims against the Issuers or the Guarantor (or
any such other obligor). A trustee who has resigned or been removed shall be

therein.

                HOLDERS LISTS AND REPORTS BY TRUSTEE AND ISSUERS

Section 701.      The Issuers to Furnish Trustee Names and Addresses.

         The Issuers will furnish or cause to be furnished to the Trustee with
respect to the Securities of each series

                  (1) semi-annually, not more than fifteen days after each
         Regular Record Date, or, in the case of any series of Securities on
         which semi-annual interest is not payable, not more than fifteen days
         after such semi-annual dates as may be specified by the Trustee, a
         list, in such form as the Trustee may reasonably require, of the names
         and addresses of the Holders as of such Regular Record Date or such
         semi-annual date, as the case may be, and

                  (2) at such other times as the Trustee may request in writing,
         within 30 days after the receipt by the Issuers or the Guarantor of any
         such request, a list of similar form and content as of a date not more
         than 15 days prior to the time such list is furnished;

provided, however, that so long as the Trustee is the Security Registrar, no
such list need be furnished.

Section 702.      Preservation of Information; Communications to Holders.

         (a) The Trustee shall preserve, in as current a form as is reasonably
practicable, the names and addresses of Holders contained in the most recent
list furnished to the Trustee as provided in Section 701 and the names and
addresses of Holders received by the Trustee in its capacity as Security
Registrar. The Trustee may destroy any list furnished to it as provided in
Section 701 upon receipt of a new list so furnished.

         (b) If three or more Holders (herein referred to as "applicants") apply
in writing to the Trustee, and furnish to the Trustee reasonable proof that each
such applicant has owned a Security for a period of at least six months
preceding the date of such application, and such application states that the
applicants' desire to communicate with other Holders with respect to their
rights under this Indenture or under the Securities and is accompanied by a copy
of the form of proxy or other communication which such applicants propose to
transmit, then the Trustee shall, within five Business Days after the receipt of
such application, at its election, either

                  (1) afford such applicants access to the information preserved
         at the time by the Trustee in accordance with Section 702(a), or

                  (2) inform such applicants as to the approximate number of
         Holders whose names and addresses appear in the information preserved
         at the time by the Trustee in accordance with

                                      -41-

<PAGE>

         Section 702(a), and as to the approximate cost of mailing to such
         Holders the form of proxy or other communication, if any, specified in
         such application.

If the Trustee shall elect not to afford such applicants access to such
information, the Trustee shall, upon the written request of such applicants,
mail to each Holder whose name and address appear in the information preserved
at the time by the Trustee in accordance with Section 702(a) a copy of the form
of proxy or other communication which is specified in such request, with
reasonable promptness after a tender to the Trustee of the material to be mailed
and of payment, or provision for the payment, of the reasonable expenses of
mailing, unless within five days after such tender the Trustee shall mail to
such applicants and file with the Commission, together with a copy of the
material to be mailed, a written statement to the effect that, in the opinion of
the Trustee, such mailing would be contrary to the best interest of the Holders
or would be in violation of applicable law. Such written statement shall specify
the basis of such opinion. If the Commission, after opportunity for a hearing
upon the objections specified in the written statement so filed, shall enter an
order refusing to sustain any of such objections or if, after the entry of an
order sustaining one or more of such objections, the Commission shall find,
after notice and opportunity for hearing, that all the objections so sustained
have been met and shall enter an order so declaring, the Trustee shall mail
copies of such material to all such Holders with reasonable promptness after the
entry of such order and the renewal of such tender; otherwise the Trustee shall
be relieved of any obligation or duty to such applicants respecting their
application.

         (c) Every Holder of Securities, by receiving and holding the same,
agrees with the Issuers, the Guarantor and the Trustee that neither the Issuers,
the Guarantor nor the Trustee nor any agent of either of them shall be held
accountable by reason of the disclosure of any such information as to the names
and addresses of the Holders in accordance with Section 702(b), regardless of
the source from which such information was derived, and that the Trustee shall
not be held accountable by reason of mailing any material pursuant to a request
made under Section 702(b).

         (d) Subject to Sections 702(a), 702(b), 702(c) and 601, if the Issuers,
the Guarantor or any other person (other than the Trustee) shall desire to
communicate with Holders of Securities to solicit or obtain from them any proxy,
consent, authorization, waiver, approval of a plan of reorganization,
arrangement or readjustment or other action ("Holder Action"), the Trustee shall
have no duty to participate in such communication or solicitation or the
processing of responses in any manner except (i) to furnish the rules and
regulations and to perform the functions referred to in Section 104 and (ii) to
receive (A) the instruments evidencing the Holder Action together with (B) the
Officers' Certificate and Opinion of Counsel referred to below. Each of the
Issuers and the Guarantor hereby covenants that any and all communications and
solicitations distributed by it in connection with any Holder Action will comply
in all material respects with applicable law, including without limitation
applicable law concerning adequacy of disclosure. The Trustee shall have no
responsibility for the accuracy or completeness of any materials circulated to
solicit any Holder Action nor for any related communications nor for the
compliance thereof with applicable law. No Holder Action shall become effective
until the Trustee shall have received from the Issuers, the Guarantor or other
person who solicited the Holder Action (1) the instruments evidencing such
Holder Action (2) (x) (in the case of Holder Action solicited by the Issuers or
the representative of the Issuers' estate if the Issuers are the debtors in any
bankruptcy or other insolvency proceeding) an Officers' Certificate and (y) (in
all cases) an Opinion of Counsel, each specifying the Holder Action taken

                                      -42-

and stating that such Holder Action has been duly and validly taken in
compliance with this Indenture in all material respects. Such Officers'
Certificate, if any, shall also certify that (after giving effect to such Holder
Action) no Event of Default or event or condition which, with notice or lapse of
time or both, would become an Event of Default has occurred and is continuing or
has not been waived.

         (e) The Depositary may grant proxies and otherwise authorize its
participants which own the Global Securities to give or take any Act which a
Holder is entitled to take under the Indenture; provided, however, that the
Depositary has delivered a list of such participants to the Trustee.

Section 703.      Reports by Trustee.

         (a) Within 60 days after May 15 of each year commencing with the first

         any requirement of the SEC in connection with the qualification of the
         Indenture under the Trust Indenture Act, provided that such

         Executive Committee of Mediacom Broadband LLC and the Board of
         Directors of Mediacom Broadband Corporation and the Guarantor and of
         the Trustee, adversely affect the interests of the Holders of the

                  (10) to change or eliminate any of the provisions of this

Section 902.      Amendments or Supplemental Indentures with Consent of Holders

         With the written consent of the Holders of not less than a majority in
aggregate principal amount of the Securities at the time Outstanding, the
Issuers and the Guarantor, when authorized by a Committee Resolution and a Board
Resolution, as the case may be, and the Trustee, at any time and from time to
time, may amend or supplement this Indenture or the Securities. However, without
the consent of each Holder affected, an amendment to this Indenture, the
Securities or the Guarantee may not:

                  (1) change the Stated Maturity of the principal of or any
         installment of interest with respect to the Securities;

<PAGE>

                  (3) change the currency of payment of principal of or interest
         on the Securities;

                  (4) impair the right to institute suit for the enforcement of

                  (8) modify or change any provision of this Indenture or the

         its Guarantee or this Indenture otherwise than in accordance with the
         terms of this Indenture.

         It shall not be necessary for any Act of the Holders under this Section
902 to approve the particular form of any proposed amendment or supplemental
indenture, but it shall be sufficient if such Act approves the substance
thereof.

         After an amendment or supplemental indenture under this Section 902
becomes effective, the Issuers and the Guarantor shall mail to each Holder a
notice briefly describing the amendment or supplemental indenture.

         An amendment or supplemental indenture which changes or eliminates any
covenant or other provision of this Indenture which has expressly been included
solely for the benefit of one or more particular series of Securities, or which
modifies the rights of the Holders of Securities of such series with respect to
such covenant or other provision, shall be deemed not to affect the rights under
this Indenture of the Holders of Securities of any other series.

Section 903.      Execution of Supplemental Indentures.

         The Trustee shall sign any supplemental indenture authorized pursuant
to this Article if the amendment contained therein does not adversely affect the
rights, duties, liabilities or immunities of the Trustee. If it does, the
Trustee may, but need not, sign such supplemental indenture. In executing, or
accepting the additional trusts created by, any supplemental indenture permitted
by this Article or the modifications thereby of the trusts created by this
Indenture, the Trustee shall be entitled to receive, and (subject to Section
601) shall be fully protected in relying upon, an Officers' Certificate and an
Opinion of Counsel from each of the Issuers and the Guarantor stating that the
execution of such supplemental indenture is authorized or permitted by this
Indenture.

Section 904.      Effect of Supplemental Indentures.

         Upon the execution of any supplemental indenture under this Article,
this Indenture shall be modified in accordance therewith, and such supplemental
indenture shall form a part of this Indenture for all purposes; and every Holder
of Securities theretofore or thereafter authenticated and delivered hereunder
shall be bound thereby.

Section 905.      Conformity with Trust Indenture Act.

         Every supplemental indenture executed pursuant to this Article shall
conform to the requirements of the Trust Indenture Act as then in effect.

Section 906.      Reference in Securities to Supplemental Indentures.

         Securities of any series authenticated and delivered after the
execution of any supplemental indenture pursuant to this Article may, and shall
if required by the Trustee, bear a notation in form approved by the Trustee as
to any matter provided for in such supplemental indenture. If the Issuers shall
so determine, new Securities of any series so modified as to conform, in the
opinion of the Trustee, the Issuers and the Guarantor, to any such supplemental
indenture may be prepared and executed by the Issuers and the Guarantor and
authenticated and delivered by the Trustee in exchange for Outstanding
Securities of such series.

                                   Article Ten
                                    COVENANTS

Section 1001.     Payment of Principal, Premium, if Any, and Interest.

         The Issuers covenant and agree for the benefit of each series of
Securities that they will duly and punctually pay the principal of (and premium,
if any) and interest on the Securities of that series in accordance with the
terms of the Securities and this Indenture. At the option of the Issuers,
payment of principal (and premium, if any) and interest may be made by wire
transfer or (subject to collection) by check mailed to the address of the Person
entitled thereto at such address as shall appear in the Security Register. The
Guarantor covenants that it will, as and when any amounts are due hereunder or
under any Security, duly and punctually pay such amounts as provided in the
Guarantee.

Section 1002.     Maintenance of Office or Agency.

         The Issuers and the Guarantor will maintain in each Place of Payment
for any series of Securities an office or agency where Securities of that series
may be presented or surrendered for registration of transfer or exchange and
where notices and demands to or upon the Issuers or the Guarantor in respect of
the Securities of that series and this Indenture may be served. The Issuers and
the Guarantor hereby initially appoint the Trustee their office or agency for
each of said purposes. The Issuers and the Guarantor will give prompt written
notice to the Trustee of the location, and any change in the location, of such
office or agency. If at any time the Issuers or the Guarantor 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

                                      -48-

<PAGE>

and demands may be made or served at the Corporate Trust Office of the Trustee,
and each of the Issuers and the Guarantor hereby appoint the Trustee as its
agent to receive all such presentations, surrenders, notices and demands.

         The Issuers and the Guarantor may also from time to time designate one
or more other offices or agencies where the Securities of one or more series 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 or the Guarantor of their
obligation to maintain an office or agency in each Place of Payment for
Securities of any series for such purposes. The Issuers and the Guarantor will
give prompt written notice to the Trustee of any such designation or rescission
and of any change in the location of any such other office or agency.

Section 1003.     Money for Securities; Payments to Be Held in Trust.

         If the Issuers shall at any time act as their own Paying Agent with
respect to any series of Securities, they will, on or before each due date of
the principal of (and premium, if any) or interest on any of the Securities of
that series, segregate and hold in trust for the benefit of the Persons entitled
thereto a sum sufficient to pay the principal (and premium, if any) or interest
so becoming due until such sums shall be paid to such Persons or otherwise
disposed of as herein provided and will promptly notify the Trustee of their
action or failure so to act.

         Whenever the Issuers or the Guarantor shall have one or more Paying
Agents for any series of Securities, they will, on or prior to each due date of
the principal of (and premium, if any) or interest on any Securities of that
series, deposit with a Paying Agent a sum sufficient to pay the principal (and
premium, if any) or interest so becoming due, such sum to be held in trust for
the benefit of the Persons entitled to such principal, premium or interest, and
(unless such Paying Agent is the Trustee) the Issuers will promptly notify the
Trustee of their action or failure so to act.

         The Issuers or the Guarantor will cause each Paying Agent for any
series of Securities other than the Trustee to execute and deliver to the
Trustee an instrument in which such Paying Agent shall agree with the Trustee,
subject to the provisions of this Section, that such Paying Agent will:

                  (1) hold all sums held by it for the payment on the principal
         of (and premium, if any) or interest on Securities of that series in
         trust for the benefit of the Persons entitled thereto until such sums
         shall be paid to such Persons or otherwise disposed of as herein
         provided;

                  (2) give the Trustee notice of any default by the Issuers (or
         any other obligor upon the Securities of that series including, without
         limitation, the Guarantor) in the making of any payment of principal
         (and premium, if any) or interest on the Securities of that series; and

                  (3) at any time during the continuance of any such default,
         upon the written request of the Trustee, forthwith pay to the Trustee
         all sums so held in trust by such Paying Agent.

         The Issuers and the Guarantor may at any time, for the purpose of
obtaining the satisfaction and discharge of this Indenture or for any other
purpose, pay, or by Issuers Order and Guarantor Order direct

                                      -49-

<PAGE>

any Paying Agent to pay, to the Trustee all sums held in trust by the Issuers or
such Paying Agent, such sums to be held by the Trustee upon the same trusts as
those upon which such sums were held by the Issuers, the Guarantor or such
Paying Agent; and, upon such payment by any Paying Agent to the Trustee, such
Paying Agent shall be released from all further liability with respect to such
money.

         Any money deposited with the Trustee or any Paying Agent, or then held
by the Issuers or the Guarantor, in trust for the payment of the principal of
(and premium, if any) or interest on any Security of any series 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 Issuers Request, or
(if then held by the Issuers or the Guarantor) shall be discharged from such
trust; and the Holder of such Security shall thereafter, as an unsecured general
creditor, look, only to the Issuers or the Guarantor 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 or the Guarantor 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 or the Guarantor cause to be mailed or published once, in a newspaper
published in the English language, customarily published on each Business Day
and of general circulation in the City, County and State of New York, or both,
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 mailing or
publication, any unclaimed balance of such money then remaining will be repaid
to the Issuers or the Guarantor.

         The Issuers shall have no obligation to make payment of principal of
(or premium, if any) or interest on any Security in immediately available funds,
except that if the Issuers shall have received original payment for Securities
in immediately available funds it shall make available immediately available
funds for payment of the principal of such Securities.

Section 1004.     Corporate Existence.

         Subject to Article Eight, the Issuers and the Guarantor will do or
cause to be done all things necessary to preserve and keep in full force and
effect their limited liability company or corporate existence, as the case may
be, the limited liability company or corporate rights, as the case may be
(charter and statutory), and franchises; provided, however, that the Issuers and
the Guarantor shall not be required to preserve any such right or franchise if
the Executive Committee or Board of Directors, as the case may be, shall
determine that the preservation thereof is no longer desirable in the conduct of
the business of the Issuers or the Guarantor and that the loss thereof is not
disadvantageous in any material respect to the Holders.

Section 1005.     Payment of Taxes and Other Claims.

         The Issuers will pay or discharge, or cause to be paid or discharged,
before the same shall become delinquent, (1) all material taxes, assessments and
governmental charges levied or imposed upon the Issuers or any Subsidiary or
upon the income, profits or property of the Issuers or any Subsidiary material
to the Issuers and their Subsidiaries taken as a whole, and (2) all lawful
claims for labor, materials and supplies which, if unpaid, might by law become a
material lien upon the property of the Issuers or any Subsidiary material to the
Issuers and their Subsidiaries taken as a whole; provided, however, that the
Issuers shall not be required to pay or discharge or cause to be paid or
discharged any such tax, assessment,

                                      -50-

<PAGE>

charge or claim whose amount, applicability or validity is being contested in
good faith by appropriate proceedings and for which adequate provision has been
made.

Section 1006.     Compliance with Laws.

         The Issuers shall comply, and shall cause each of their Subsidiaries
material to the Issuers and their Subsidiaries taken as a whole to comply, with
all applicable statutes, rules, regulations, orders and restrictions of the
United States of America, all states and municipalities thereof, and of any
governmental regulatory authority, in respect of the conduct of their respective
businesses and the ownership of their respective properties, except for such
noncompliances as would not in the aggregate have a material adverse effect on
the financial condition or results of operations of the Issuers and their
Subsidiaries, taken as a whole.

Section 1007.     Statement by Officers as to Default.

         The Issuers will each deliver to the Trustee, within 120 days after the
end of each fiscal year of the Issuers ending after the date hereof, a
certificate of the principal executive officer, principal financial officer or
principal accounting officer of the managing member, on behalf of Mediacom
Broadband LLC, and of Mediacom Broadband Corporation stating whether or not to
the best knowledge of the signers thereof Mediacom Broadband LLC or Mediacom
Broadband Corporation, as the case may be, is in default in the performance and
observance of any of the terms, provisions and conditions of this Indenture, and
if Mediacom Broadband LLC or Mediacom Broadband Corporation, as the case may be,
shall be in default, specifying all such defaults and the nature and status
thereof of which they may have knowledge.

         The Guarantor will deliver to the Trustee, within 120 days after the
end of each fiscal year ending after the date hereof, a certificate of its
principal executive officer, principal financial officer or principal accounting
officer stating whether or not to the best knowledge of the signers thereof the
Guarantor is in default in the performance and observance of any of the terms,
provisions and conditions of this Indenture, and the Guarantor shall be in
default, specifying all such defaults and the nature and status thereof of which
they may have knowledge.

Section 1008.     Waiver of Certain Covenants.

         The Issuers or the Guarantor, as the case may be, may omit in any
particular instance to comply with any term, provision or condition set forth in
Section 1007 if before or after the time for such compliance the Holders of at
least a majority in principal amount of the Outstanding Securities (taken
together as one class) shall, by Act of such Holders, either waive such
compliance in such instance or generally waive compliance with such term,
provision or condition except to the extent so expressly waived, and, until such
waiver shall become effective, the obligations of the Issuers and the Guarantor
and the duties of the Trustee in respect of any such term, provision or
condition shall remain in full force and effect.

Article Eleven

                            REDEMPTION OF SECURITIES

Section 1101.     Applicability of Article.

         Securities of any series which are redeemable before their Stated
Maturity shall be redeemable in accordance with their terms and (except as
otherwise specified as contemplated by Section 301 for Securities of any series)
in accordance with this Article.

Section 1102.     Election to Redeem; Notice to Trustee.

         The election of the Issuers to redeem any Securities shall be evidenced
by Committee Resolution and a Board Resolution. In case of any redemption at the
election of the Issuers of less than all the Securities of any series, the
Issuers and the Guarantor shall, at least 45 days prior to the Redemption Date
fixed by the Issuers (unless a shorter notice shall be satisfactory to the
Trustee), notify the Trustee of such Redemption Date and of the principal amount
of Securities of such series to be redeemed, such notice to be accompanied by a
written statement signed by an authorized officer of the Issuers the Guarantor
stating that no defaults in the payment of interest or Events of Default with
respect to the Securities of that series have occurred (which have not been
waived or cured). In the case of any redemption of Securities prior to the
expiration of any restriction on such redemption provided in the terms of such
Securities or elsewhere in this Indenture, the Issuers and the Guarantor shall
furnish the Trustee an Officers' Certificate evidencing compliance with such
restriction.

Section 1103.     Selection by Trustee of Securities to Be Redeemed.

         If less than all the Securities of any series are to be redeemed, the
particular Securities to be redeemed shall be selected not more than 60 days
prior to the Redemption Date by the Trustee, from the Outstanding Securities of
such series not previously called for redemption, by such method as the Trustee
in its sole discretion shall deem fair and appropriate and which may provide for
the selection or redemption of portions (equal to the minimum authorized
denomination for Securities of that series or any integral multiple thereof) of
the principal amount of Securities of such series of a denomination larger than
the minimum authorized denomination for Securities of that series.

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

         For all purposes of this Indenture, unless the context otherwise
requires, all provisions relating to the redemption of Securities shall relate,
in the case of any Securities redeemed or to be redeemed only in part, to the
portion of the principal amount of such Securities which has been or is to be
redeemed.

                                      -52-

Section 1104.     Notice of Redemption.

         Notice of redemption shall be given by first-class mail, postage
prepaid, mailed not less than 45 nor more than 60 days prior to the Redemption
Date, to each Holder of Securities to be redeemed, at his address appearing in
the Security Register. Any notice which is mailed in the manner herein provided
shall be conclusively presumed to have been duly given, whether or not such
Holder receives the notice. Failure to give notice by mail, or any defect in the
notice to any such Holder in respect of any Security, shall not affect the
validity of the proceedings for the redemption of any other Security.

         All notices of redemption shall state:

                  (1) the Redemption Date,

                  (2) the Redemption Price and any accrued interest,

                  (3) if less than all the Outstanding Securities of any series
         are to be redeemed, the identification (and, in the case of partial
         redemption, the principal amounts) of the particular Securities to be
         redeemed,

                  (4) that on the Redemption Date the Redemption Price and any
         accrued interest will become due and payable upon each such Security to
         be redeemed together with accrued interest thereon and, if applicable,
         that interest thereon will cease to accrue on and after said date,

                  (5) the place or places where such Securities are to be
         surrendered for payment of the Redemption Price and any accrued
         interest,

                  (6) that the redemption is for a sinking fund, if such is the
         case, and

                  (7) the CUSIP number of the Securities being redeemed.

         Notice of redemption of Securities to be redeemed at the election of
the Issuers shall be given by the Issuers or, at the Issuers' request, by the
Trustee in the name and at the expense of the Issuers.

Section 1105.     Deposit of Redemption Price.

         On or prior to any Redemption Date, the Issuers or the Guarantor shall
deposit with the Trustee or with a Paying Agent (or, if the Issuers or the
Guarantor are acting as their own Paying Agent, segregate and hold in trust as
provided in Section 1003) an amount of money, in funds immediately available on
the due date, sufficient to pay the Redemption Price of, and (except if the
Redemption Date shall be an Interest Payment Date) accrued interest on, all the
Securities which are to be redeemed on that date.

Section 1106.     Securities Payable on Redemption Date.

         Notice of redemption having been given as aforesaid, the Securities so
to be redeemed shall, on the Redemption Date, become due and payable at the
Redemption Price therein specified together with

                                      -53-

<PAGE>

accrued interest thereon, and from and after such date (unless the Issuers or
the Guarantor shall default in the payment of the Redemption Price and accrued
interest) such Securities shall cease to bear interest. Upon surrender of any
such Security for redemption in accordance with said notice, such Security shall
be paid by the Issuers at the Redemption Price, together with accrued interest
to the Redemption Date; provided, however, that installments of interest whose
Stated Maturity is on the Redemption Date shall be payable to the Holders of
such Securities, or one or more Predecessor Securities, registered as such at
the close of business on the relevant Record Dates according to their terms and
the provisions of Section 307.

         If any Security called for redemption shall not be so paid upon
surrender thereof for redemption, the principal (and premium, if any) shall,
until paid, bear interest from the Redemption Date at the rate prescribed
therefor in the Security.

         The Trustee shall not redeem any Securities of any series pursuant to
this Article (unless all Outstanding Securities of such series are to be
redeemed) or mail or give any notice of redemption of Securities during the
continuance of an Event of Default hereunder known to the Trustee with respect
to such series, except that, where the mailing of notice of redemption of any
Securities shall theretofore have been made, the Trustee shall redeem or cause
to be redeemed such Securities, provided that it shall have received from the
Issuers or the Guarantor a sum sufficient for such redemption. Except as
aforesaid, any moneys theretofore or thereafter received by the Trustee shall,
during the continuance of such Event of Default, be deemed to have been
collected under Article Five and held for the payment of all such Securities of
such series. In case such Event of Default shall have been waived as provided in
Section 513 or the default cured on or before the sixtieth day preceding the
Redemption Date, such moneys shall thereafter be applied in accordance with the
provisions of this Article.

Section 1107.     Securities Redeemed in Part.

         Any Security which is to be redeemed only in part shall be surrendered
at a Place of Payment therefor (with, if the Issuers, the Guarantor or the
Trustee so requires, due endorsement by, or a written instrument of transfer in
form satisfactory to the Issuers, the Guarantor and the Trustee duly executed
by, the Holder thereof or his attorney duly authorized in writing), and the
Issuers shall execute, the Guarantor shall execute guarantees on and the Trustee
shall authenticate and deliver to the Holder of such Security without service
charge, a new Security or Securities of the same series, of any authorized
denomination as requested by such Holder, in aggregate principal amount equal to
and in exchange for the unredeemed portion of the principal of the Security so
surrendered.

                                 Article Twelve
                                  SINKING FUNDS

Section 1201.     Applicability of Article.

         The provisions of this Article shall be applicable to any sinking fund
for the retirement of Securities of a series except as otherwise specified as
contemplated by Section 301 for Securities of such series.

                                      -54-

<PAGE>

         The minimum amount of any sinking fund payment provided for by the
terms of Securities of any series is herein referred to as a "mandatory sinking
fund payment," and any payment in excess of such minimum amount provided for by
the terms of Securities of any series is herein referred to as an "optional
sinking fund payment." If provided for by the terms of Securities of any series,
the cash amount of any sinking fund payment may be subject to reduction as
provided in Section 1202. Each sinking fund payment shall be applied to the
redemption of Securities of any series as provided for by the terms of
Securities of such series.

Section 1202.     Satisfaction of Sinking Fund Payments with Securities.

         The Issuers (1) may deliver Outstanding Securities of a series (other
than any previously called for redemption) and (2) may apply as credit
Securities of a series which have been redeemed either at the election of the
Issuers pursuant to the terms of such Securities or through the application of
permitted optional sinking fund payments pursuant to the terms of such
Securities, in each case in satisfaction of all or any part of any sinking fund
payment with respect to the Securities of such series required to be made
pursuant to the terms of such Securities as provided for by the terms of such
series; provided that such Securities have not been previously so credited. Such
Securities shall be received and credited for such purpose by the Trustee at the
Redemption Price specified in such Securities for redemption through operation
of the sinking fund and the amount of such sinking fund payment shall be reduced
accordingly.

Section 1203.     Redemption of Securities for Sinking Fund.

         Not less than 60 days prior to each sinking fund payment date for any
series of Securities, the Issuers (1) will deliver to the Trustee an Officers'
Certificate (A) stating that no defaults in the payment of interest or Events of
Default with respect to Securities of that series have occurred (which have not
been waived or cured), (B) specifying the amount of the next ensuing sinking
fund payment for that series pursuant to the terms of Securities of that series,
(C) stating whether or not the Issuers intend to exercise their right, if any,
to make an optional sinking fund payment with respect to such series on the next
ensuing sinking fund payment date and, if so, specifying the amount of such
optional sinking fund payment and (D) specifying the portion of such sinking
fund payment, if any, which is to be satisfied by payment of cash and the
portion thereof, if any, which is to be satisfied by delivering and crediting
Securities of that series pursuant to Section 1202 and (2) will also deliver to
the Trustee any Securities to be so delivered. Not less than 30 days before each
such sinking fund payment date the Trustee shall select the Securities of such
series to be redeemed upon such sinking fund payment date in the manner
specified in Section 1103 and cause notice of the redemption thereof to be given
in the name of and at the expense of the Issuers in the manner provided in
Section 1104. Such notice having been duly given, the redemption of such
Securities shall be made upon the terms and in the manner stated in Sections
1105, 1106 and 1107. Failure of the Issuers, on or before any such 60th day, to
deliver such Officers' Certificate and Securities specified in this Section, if
any, shall not constitute a default but shall constitute, on and as of such
date, the irrevocable election of the Issuers (a) that the mandatory sinking
fund payment for such series due on the next succeeding sinking fund payment
date shall be paid entirely in cash without the option to deliver or credit
Securities of such series in respect thereof and (b) that the Issuers will make
no optional sinking fund payment with respect to Securities of such series as
provided in this Article.

                                      -55-

<PAGE>

         The Trustee shall not redeem or cause to be redeemed any Security of a
series with sinking fund moneys or mail any notice of redemption of Securities
of such series by operation of the sinking fund during the continuance of a
default in payment of interest on such Securities or of any Event of Default
with respect to such series except that, where the mailing of notice of
redemption of any Securities shall therefore have been made, the Trustee shall
redeem or cause to be redeemed such Securities, provided that it shall have
received from the Issuers a sum sufficient for such redemption. Except as
aforesaid, any moneys in the sinking fund for such series at the time when any
such default or Event of Default shall occur, and any moneys thereafter paid
into the sinking fund, shall, during the continuance of such default or Event of
Default, be deemed to have been collected under Article Five and held for the
payment of all such Securities of such series. In case such Event of Default
shall have been waived as provided in Section 513 or the default cured on or
before the 60th day preceding the sinking fund payment date, such moneys shall
thereafter be applied on the next succeeding sinking fund payment date in
accordance with this Section to the redemption of such Securities.

                                Article Thirteen
                             GUARANTEE OF SECURITIES

Section 1301.     Unconditional Guarantee.

         Subject to the provisions of this Article Thirteen, the Guarantor
hereby unconditionally guarantees, on an unsecured, unsubordinated basis, to
each Holder of a Security authenticated and delivered by the Trustee and to the
Trustee and its successors, irrespective of the validity and enforceability of
this Indenture, the Securities or the obligations of the Issuers to the Holders
or the Trustee hereunder or thereunder, that: (a) the principal of (and premium,
if any) and interest on the Securities will be duly and punctually paid in full
when due, whether at maturity, by acceleration, call for redemption or otherwise
and all obligations of the Issuers or the Guarantor to the Holders or the
Trustee hereunder or thereunder (including amounts due the Trustee under Section
607 hereof) or under the Securities (including fees, expenses or other
disbursements) will be promptly paid in full or performed, all in accordance
with the terms hereof and thereof; and (b) in case of any extension of time of
payment or renewal of any Securities or any of such other obligations, the same
will be promptly paid in full when due or performed in accordance with the terms
of the extension or renewal, whether at maturity, by acceleration, call for
redemption, purchase or otherwise (all such obligations guaranteed by the
Guarantor, the "Guaranteed Obligations"). Failing payment when due of any amount
so guaranteed, or failing performance of any other obligation of the Issuers to
the Holders, for whatever reason, the Guarantor will be obligated to pay, or to
perform or cause the performance of the same immediately. An Event of Default
under this Indenture or the Securities shall constitute an event of default
under this Guarantee, and shall entitle the Holders of Securities or the Trustee
to accelerate the obligations of the Guarantor hereunder in the same manner and
to the same extent as the obligations of the Issuers.

         The Guarantor agrees to pay any and all fees and expenses (including
reasonable attorney's fees and expenses) incurred by the Trustee or the Holders
in enforcing any rights under this Article Thirteen with respect to the
Guarantor. Without limiting the generality of the foregoing, this Guarantee
guarantees, to the extent provided herein, the payment of all amounts that
constitute part of the Guaranteed Obligations and would be owed by the Issuers
under this Indenture or the Securities but for the fact that they

                                      -56-

<PAGE>

are unenforceable or not allowable due to the existence of a bankruptcy,
reorganization or similar proceeding involving the Issuers.

         No stockholder, officer, director, employee or incorporator, past,
present or future, of the Guarantor, as such, shall have any personal liability
under this Guarantee by reason of his, her or its status as such stockholder,
officer, director, employee or incorporator.

Section 1302.     Execution and Delivery of Guarantee.

         The Guarantee to be endorsed on the Securities pursuant to Section 204
shall be deemed to include the terms of the Guarantee set forth in this Article
Thirteen. The Guarantor hereby agrees to execute the Guarantee in the form
established pursuant to Section 204 to be endorsed on each Security
authenticated and delivered by the Trustee.

         The Guarantee shall be executed on behalf of the Guarantor by two
Officers of the Guarantor. The signature of such Officer on the Guarantee may be
manual or facsimile.

         A Guarantee bearing the manual or facsimile signature of an individual
who was at any time the proper officer of the Guarantor shall bind the
Guarantor, notwithstanding that such individual has ceased to hold such office
prior to the authentication and delivery of the Security on which the Guarantee
is endorsed or did not hold such office at the date of the Guarantee.

         The delivery of any Security by the Trustee after the authentication
thereof hereunder, shall constitute due delivery of the Guarantee endorsed
thereon on behalf of the respective Guarantor. The Guarantor hereby agrees that
the Guarantee set forth in this Article Thirteen and in Section 204 shall remain
in full force and effect notwithstanding any failure to endorse a Guarantee on
any Security.

Section 1303.     Obligations of the Guarantor Unconditional.

         Nothing contained in this Article Thirteen or elsewhere in this
Indenture or in any Security is intended to or shall impair, as between the
Guarantor and the Holders and the Trustee, the obligation of the Guarantor,
which is absolute and unconditional, to pay to the Holders and the Trustee the
principal of (and premium, if any), and interest on the Securities (and to the
Trustee amounts due under Section 607) as and when the same shall become due and
payable in accordance with the provisions of this Guarantee, nor shall anything
herein or therein prevent the Trustee or any Holder from exercising all remedies
otherwise permitted by applicable law upon default under this Indenture. Without
limiting the generality of the foregoing, it is agreed that the occurrence of
any one or more of the following shall not affect the liability of the Guarantor
hereunder:

         (a) the lack of validity, regularity or enforceability of this
Indenture or the Securities with respect to the Issuers or any agreement or
instrument relating thereto;

         (b) any change in the time, manner or place of payment of, or in any
other term of any of the Securities, or any other amendment or waiver of or any
consent to departure from this Indenture;

                                      -57-

<PAGE>

         (c) any amendment or modification of or deletion from or addition or
supplement to or other change in the Guarantee, the Indenture or the Securities
or any other instrument or agreement applicable to any of the parties to the
Guarantee, the Indenture or the Securities;

         (d) any furnishing or acceptance of any security or any guarantee or
other liability of any Subsidiary or any other party, or any release of any
security or any guarantee or other liability of any Subsidiary or any other
party, for the Guaranteed Obligations, or the failure of any security or any
guarantee or other liability of any Subsidiary or any other party or the failure
of any Person to perfect any interest in any collateral;

         (e) any failure, omission or delay on the part of the Issuers to
conform or comply with any term of the Indenture or the Securities or any other
instrument or agreement referred to in paragraph (a) above, in cluding, without
limitation, failure to give notice to the Guarantor or the Trustee of the
occurrence of an Event of Default;

         (f) any waiver of the payment, performance or observance of any of the
obligations, conditions, covenants or agreements contained in the Guarantee, the
Indenture or the Securities, or any other waiver, consent, extension indulgence,
compromise settlement release or other action or inaction under or in respect of
the Guarantee, the Indenture or the Securities or any other instrument or
agreement referred to in paragraph (a) above or any obligation or liability of
the Issuers or any exercise or non-exercise of any right, remedy, power or
privilege under or in respect of any such instrument or agreement or any such
obligation or liability;

         (g) any failure, omission or delay on the part of the Trustee or any
Holder of Securities to enforce, assert, exercise or continue exercising any
right, power or remedy conferred on it in the Guarantee or the Indenture, or any
such failure, omission or delay on the part of the Trustee or any Holder of
Securities in connection with the Guarantee, the Indenture or the Securities, or
any other action on the part of the Trustee or any Holder of Securities;

         (h) the assignment of any right, title or interest of the Trustee or
any Holder in this Indenture or the Securities to any other Person;

         (i) any voluntary or involuntary bankruptcy, insolvency, suspension of
payments, reorganizations, arrangement, readjustment, assignment for the benefit
of creditors, receivership, liquidation or similar proceedings with respect to
the Issuers, the Guarantor or any other Person or any of their respective
properties or creditors, or any action taken by any trustee, receiver or similar
officer or by any court in any such proceeding;

         (j) any limitation on the liability or obligations of the Issuers or
any other Person under the Guarantee, the Indenture or the Securities, or any
partial discharge, cancellation or unenforceability of the Guarantee, the
Indenture or the Securities or any other agreement or instrument referred to in
paragraph (c) above or any term hereof, to the extent not mutually agreed upon
by the parties hereto;

         (k) any merger or consolidation of the Issuers or the Guarantor into or
with any other corporation or any sale, lease or transfer of any of the assets
of the Issuers or the Guarantor to any other Person;

                                      -58-

<PAGE>

         (l) any change in the ownership of any shares of Capital Stock of the
Guarantor, or any change in the corporate relationship between the Issuers and
the Guarantor, or any termination of such relationship, or any change in the
corporate existence, structure, or ownership of the Issuers;

         (m) any release or discharge, by operation of law, of the Guarantor
from the performance or observance of any obligation, covenant or agreement
contained in the Guarantee, the Indenture or the Securities;

         (n) any action, failure, omission or delay on the part of the Trustee
or any Holder of Securities that may impede any Guarantor from acquiring or
subrogating such Holders or Trustee's rights or benefits; or

         (o) any other occurrence, circumstance, happening or event whatsoever,
whether similar or dissimilar to the foregoing, whether foreseen or unforeseen,
and any other circumstance that might otherwise constitute a legal defense or
discharge of the liabilities of the Guarantor or that might otherwise limit
recourse against the Guarantor; it being the intent of the Guarantor that its
obligations hereunder shall not be discharged except by payment of all amounts
owing pursuant to this Indenture or the Securities.

         The Guarantee shall continue to be effective or be reinstated, as the
case may be, if at any time any payment or performance with respect to any of
the Securities is rescinded or must otherwise be returned by the Trustee, any
Holder or any other Person upon the insolvency, bankruptcy or reorganization of
the Issuers or otherwise, all as though such payment or performance had not been
made or occurred. In the event that any payment or any part thereof is rescinded
or must otherwise be returned, the Securities shall be reinstated and deemed
reduced only by such amount paid and not so rescinded or returned. The
obligations of the Guarantor under the Guarantee shall not be subject to
reduction, termination or other impairment by any set-off, recoupment,
counterclaim or defense or for any other reason.

Section 1304.     Waivers.

         The Guarantor hereby irrevocably waives, to the extent permitted by
applicable law:

         (a) promptness, demand for payment, diligence, presentment, notice of
acceptance and any other notice with respect to any of the Guaranteed
Obligations and the Guarantee;

         (b) any requirement that the Trustee, any Holder or any other Person
protect, secure, perfect or insure any Lien or any property subject thereto or
exhaust any right, sue or take any action against the Issuers or any other
Person, or obtain any relief pursuant to this Indenture or pursue any other
available remedy prior to making a claim against the Guarantor hereunder;

         (c) all right to trial by jury in any action, proceeding or
counterclaim arising out of or relating to this Indenture or the Securities;

                                      -59-

<PAGE>

         (d) filing of claims with a court in the event of insolvency or
bankruptcy of the Issuers, any right to require a proceeding first against the
Issuers, protest or notice with respect to such Security or the Indebtedness
evidenced thereby and all demands whatsoever;

         (e) any defense arising by reason of any claim or defense based upon an
election of remedies by the Trustee or any Holder that in any manner impairs,
reduces, releases or otherwise adversely affects its subrogation, contribution
or reimbursement rights or other rights to proceed against the Issuers or any
other Person;

         (f) any right to which it may be entitled to have the assets of the
Issuers first be used as payment of the Issuers' or the Guarantor's obligations
hereunder prior to any amounts being claimed from or paid by the Guarantor
hereunder; or

         (g) any duty on the part of the Trustee or any Holder to disclose to
the Guarantor any matter, fact or thing relating to the business, operation or
condition of the Issuers and its assets now known or hereafter known by the
Trustee or such Holder.

Section 1305.     Amendment, Etc.

         No amendment, modification or waiver of any provision of this Indenture
relating to the Guarantor or consent to any departure by the Guarantor or any
other Person from any such provision will in any event be effective unless it is
signed by the Guarantor and the Trustee.

         This instrument may be executed in any number of counterparts, each of
which so executed shall be deemed to be an original, but all such counterparts
shall together constitute but one and the same instrument.

by the Issuers to be owned or held by or for the account of any of the

such Person may certify or give an opinion with respect to some matters and one
or more other such Persons as to other matters, and any such Person may certify
or give an opinion as to such matters in one or several documents.

         Any certificate or opinion of an officer of the Issuers or the
Guarantor may be based, insofar as it relates to legal matters, upon a
certificate or opinion of, or representations by, counsel, unless such officer
knows, or in the exercise of reasonable care should know, that the certificate
or opinion or representations with respect to such matters is erroneous. Any
such certificate or Opinion of Counsel may be based, insofar as it relates to
factual matters, upon a certificate or opinion of, or representations by, an
officer or officers of the Issuers or the Guarantor stating that the information
with respect to such factual matters is in the possession of the Issuers or the
Guarantor, unless such counsel knows, or in the exercise of reasonable care
should know, that the certificate or opinion or representations with respect to
such matters are erroneous.

         Where any Person is required to make, give or execute two or more
applications, requests, consents, certificates, statements, opinions or other
instruments under this Indenture, they may, but need not, be consolidated and
form one instrument.

SECTION 104.      Acts of Holders.

     (a) Any request, demand, authorization, direction, notice, consent, waiver
or other action provided by this Indenture to be given or taken by Holders may
be embodied in and evidenced by one or more instruments of substantially similar
tenor signed by such Holders in person or by an agent duly appointed in writing;
and, except as herein otherwise expressly provided, such action shall become
effective when such instrument or instruments are delivered to the Trustee and,
where it is hereby expressly required, to the Issuers or the Guarantor. Such
instrument or instruments (and the action embodied therein and evidenced
thereby) are herein sometimes referred to as the "Act" of the Holders signing
such instrument or instruments. Proof of execution of any such instrument or of
a writing appointing any such agent shall be sufficient for any purpose of this
Indenture and (subject to Section 601) conclusive in favor of the Trustee and
the Issuers or the Guarantor, if made in the manner provided in this Section.

         (b) The fact and date of the execution of any such instrument or
writing, or the authority of the Person executing the same, may be proved in
accordance with such reasonable rules and regulations as may be prescribed by
the Trustee or in any reasonable manner which the Trustee deems sufficient.

         (d) If the Issuers or the Guarantor shall solicit from the Holders any
request, demand, authorization, direction, notice, consent, waiver or other Act,

Committee and/or a Board Resolution, as the case may be, fix in advance a re-

                                       -9-

<PAGE>

cord date for the determination of Holders entitled to give such request,
demand, authorization, direction, notice, consent, waiver or other Act, but the
Issuers or the Guarantor shall have no obligation to do so. Notwithstaning Trust
Indenture Act Section 316(c), such record date shall be the record date
specified in or pursuant to such Committee Resolution and/or Board Resolution,
which shall be a date not earlier than the date 30 days prior to the first
solicitation of Holders generally in connection therewith and not later than the
date such solicitation is completed. If such a record date is fixed, such
request, demand, authorization, direction, notice, consent, waiver or other Act
maybe given before or after such record date, but only the Holders of record at
the close of business on such record date shall be deemed to be Holders for the
purposes of determining whether Holders of the requisite proportion of
Outstanding Securities shall be computed as of such record date; provided,
however, that no such authorization, agreement or consent by such Holders on
such record date shall be deemed effective unless it shall become effective
pursuant to the provisions of this Indenture not later than eleven months after
the record date.

         (e) Any request, demand, authorization, direction, notice, consent,
waiver or other Act of the Holder of any Security shall bind every future Holder
of the same Security and the Holder of every Security issued upon the
registration of transfer thereof or in exchange therefor or in lieu thereof in
respect of anything done, omitted or suffered to be done by the Trustee or the
Issuers or the Guarantor in reliance thereon, whether or not notation of such
action is made upon such Security.

         Any request, demand, authorization, direction, notice, consent, waiver
or Act of Holders or other document provided or permitted by this Indenture to
be made upon, given or furnished to, or filed with,

               (1) the Trustee by any Holder or by the Issuers or the Guarantor
         shall be sufficient for every purpose hereunder if made, given,
         furnished or filed in writing to or with the Trustee at its Corporate
         Trust Office, Attention: Corporate Trust Department, or

               (2) the Issuers or the Guarantor by the Trustee or by any Holder
         shall be sufficient for every purpose hereunder (unless otherwise
         herein expressly provided) if in writing and mailed, first-class
         postage prepaid, to the Issuers or the Guarantor, as the case may be,
         addressed to them or it at the address of their or its principal office
         specified in the first paragraph of this instrument or at any other
         address previously furnished in writing to the Trustee by the Issuers
         or the Guarantor, to the attention of the general counsel of the
         Issuers or the Guarantor, as the case may be.

SECTION 106.      Notice to Holders; Waiver.

         Where this Indenture provides for notice to Holders of any event, such
notice shall be sufficiently given (unless otherwise herein expressly provided)
if in writing and mailed, first-class postage prepaid, to each Holder affected
by such event, at his address as it appears in the Security Register, not later
than the latest date, and not earlier than the earliest date, prescribed for the
giving of such notice. In any case where notice to Holders is given by mail,
neither the failure to mail such notice, nor any defect in any notice so mailed,
to any particular Holder shall affect the sufficiency of such notice with
respect to other Holders. Where this Indenture provides for notice in any
manner, such notice may be waived in writing by the Person entitled to receive
such notice, either before or after the event, and such waiver

                                      -10-

<PAGE>

shall be the equivalent of such notice. Waivers of notice by Holders shall be
filed with the Trustee, but such filing shall not be a condition precedent to
the validity of any action taken in reliance upon such waiver.

         In case by reason of the suspension of regular mail service or by
reason of any other case it shall be impracticable to give such notice by mail,
then such notification as shall be made with the approval of the Trustee shall
constitute a sufficient notification for every purpose hereunder.

SECTION 107.      Effect of Headings and Table of Contents.

         The Article and Section headings herein and the Table of Contents are
for convenience only and shall not affect the construction hereof.

SECTION 108.      Successors and Assigns.

         All covenants and agreements in this Indenture by each of the Issuers
or the Guarantor shall bind each of its successors and assigns, whether so
expressed or not.

SECTION 109.      Separability Clause.

         In case any provision in this Indenture, the Securities or the
Guarantee shall be invalid, illegal or unenforceable, the validity, legality and
enforceability of the remaining provisions shall not in any way be affected or
impaired thereby.

SECTION 110.      Benefits of Indenture.

         Nothing in this Indenture, the Securities or the Guarantee, express or
implied, shall give to any Person (other than the parties hereto, any agent and
their successors hereunder and each of the Holders) any benefit or any legal or
equitable right, remedy or claim under this Indenture.

SECTION 111.      Conflict with Trust Indenture Act.

         If any provision hereof limits, qualifies or conflicts with another
provision which is required or deemed to be included in this Indenture by any of
the provisions of the Trust Indenture Act, such required or deemed provision
shall control.

SECTION 112.      Governing Law.

         This Indenture, the Securities and the Guarantee shall be governed by
and construed in accordance with the laws of the State of New York.

SECTION 113.      Legal Holidays.

         In any case where any Interest Payment Date, Redemption Date or Stated
Maturity of any Security shall not be a Business Day at any Place of Payment,
then (notwithstanding any other provision of this Indenture or of the
Securities) payment of interest or principal (and premium, if any) need not be

                                      -11-

<PAGE>

made at such Place of Payment on such date, but may be made on the next
succeeding Business Day at such Place of Payment with the same force and effect
as if made on the Interest Payment Date or Redemption Date, or at the Stated
Maturity, provided that no interest shall accrue for the period from and after
such Interest Payment Date, Redemption Date or Stated Maturity, as the case may
be.

SECTION 114.      No Personal Liability of Directors, Officers, Employees,
                  Stockholders or Incorporators.

         No manager, director, officer, employee, member, shareholder, partner
or incorporator of the Issuers or the Guarantor or any Subsidiary, as such,
shall have any liability for any obligations of the Issuers or the Guarantor
under the Securities, this Indenture or for any claim based on, in respect of,
or by reason of, such obligations or their creation. Each Holder by accepting a
Security waives and releases all such liability. Such waiver and release are
part of the consideration for the issuance of the Securities of each series.

         (c)      (1) If at any time the Depositary for a Global Security
         notifies the Issuers that it is unwilling or unable to continue as
         Depositary for such Global Security or if at any time the Depositary
         for the Securities for such series shall no longer be eligible or in
         good standing under the Securities Exchange Act of 1934, as amended, or
         other applicable statute or regulation, the Issuers shall appoint a
         successor Depositary with respect to such Global Security. If a
         successor Depositary for such Global Security is not appointed by the
         Issuers within 90 days after the Issuers receive such notice or becomes
         aware of such ineligibility, the Issuers will execute an Issuers Order
         for the authentication and delivery of individual Securities of such
         series in exchange for such Global Security, and the Trustee, upon
         receipt of such Issuers Order, will authenticate and deliver individual
         Securities of such series of like tenor and terms in definitive form in
         an aggregate principal amount equal to the principal amount of the
         Global Security in exchange for such Global Security and the Guarantor
         shall execute Guarantees thereon.

         continuing or an event shall have occurred which with the giving of
         notice or lapse of time or both, would constitute an Event of Default
         with respect to the Securities represented by such Global Security, the
         Trustee, upon receipt of an Issuers Order for the authentication and
         delivery of individual Securities of such series in exchange for such
         Global Security, will authenticate and deliver individual Securities of
         such series of like tenor and terms in definitive form in an aggregate
         principal amount equal to the principal amount of the Global Security
         in exchange for such Global Security and the Guarantor shall execute
         Guarantees thereon.

                  (3) The Issuers may at any time and in their sole discretion
         determine that the Securities of any series issued or issuable in the
         form of one or more Global Securities shall no longer be represented by
         such Global Security or Securities. In such event the Issuers will
         execute, and the Trustee, upon receipt of an Issuers Order for the
         authentication and delivery of individual Securities of such series in
         exchange in whole or in part for such Global Security, will
         authenticate and deliver individual Securities of such series of like
         tenor and terms in definitive form in an aggregate principal amount
         equal to the principal amount of such Global Security or Securities
         representing such series to be so exchanged for such Global Security or
         Securities and the Guarantor shall execute Guarantees thereon.

                  (4) If specified by the Issuers pursuant to Section 301 with
         respect to Securities issued or issuable in the form of a Global
         Security, the Depositary for such Global Security may surrender such
         Global Security in exchange in whole or in part for individual
         Securities of such series of like tenor and terms in definitive form on
         such terms as are acceptable to the Issuers and such Depositary.
         Thereupon the Issuers shall execute, the Guarantor shall execute
         Guarantees on, and the Trustee shall authenticate and deliver, without
         service charge, (i) to each Person specified by such Depositary a new
         Security or Securities of the same series of like tenor and terms and
         of any authorized denomination of $1,000 and any integral multiple
         thereof as requested by such Person in aggregate principal amount equal
         to and in exchange for such Person's beneficial interest in the Global
         Security; and (ii) to such Depositary a new Global Security of like
         tenor and terms and in a denomination equal to the difference, if any,
         between the principal amount of the surrendered Global Security and the
         aggregate principal amount of Securities delivered to Holders thereof.

         Guarantees on, and the Trustee will authenticate and deliver individual
         Securities in definitive registered form in authorized denominations of
         $1,000 and any integral multiple thereof. Upon the exchange of a Global
         Security for individual Securities, such Global Security shall be
         cancelled by the Trustee. Securities issued in exchange for a Global
         Security pursuant to this Section shall be registered in such names and
         in such authorized denominations as the Depositary for such Global
         Security, pursuant to instructions from its direct or indirect
         participants or otherwise, shall instruct the Trustee. The Trustee
         shall deliver such Securities to the persons in whose names such
         Securities are so registered.

         The form of Guarantee shall be set forth on the Securities as follows:

         Guarantee shall be governed by and construed in accordance with the
         laws of the State of New York, without regard to conflict of law
         principles thereof.

except as to denomination and except as may otherwise be provided in or pursuant
to such Committee Resolution and Board Resolution and set forth in such
Officers' Certificate, as described above, or in any such indenture supplemental
hereto.

         If any of the terms of the Securities of any series are established by
action taken pursuant to a Committee Resolution and Board Resolution, a copy of
an appropriate record of such action shall be certified by the secretary or an
assistant secretary of the managing member of Mediacom Broadband LLC, of
Mediacom Broadband Corporation and of the Guarantor and delivered to the Trustee
at or prior to the delivery of the Officers' Certificate setting forth the terms

SECTION 302.      Denominations.

         The Securities of each series shall be issuable in registered form
without coupons in such denominations as shall be specified as contemplated by

Securities of any series, the Securities of such series shall be issuable in
denominations of $1,000 and any integral multiple thereof.

SECTION 303.      Execution, Authentication, Delivery and Dating.

         The Securities shall be executed on behalf of Mediacom Broadband LLC by

secretary or one of the assistant secretaries, of its managing member and on

Directors, its president or one of its vice presidents, under its corporate seal
reproduced thereon attested by its secretary or one of its assistant
secretaries. The signature of any of these officers on the Securities may be

         Securities bearing the manual or facsimile signatures of individuals
who were, in the case of Mediacom Broadband LLC, at any time the proper officers
of its managing member and, in the case of Mediacom Broadband Corporation, at
any time the proper officers of Mediacom Broadband Corporation shall bind
Mediacom Broadband LLC and Mediacom Broadband Corporation, as the case may be,
notwithstanding that such individuals or any of them have ceased to hold such
offices prior to the authentication and delivery of such Securities or did not
hold such offices at the date of such Securities.

         At any time and from time to time after the execution and delivery of
this Indenture, the Issuers may deliver Securities of any series executed by the
Issuers to the Trustee for authentication, together with an Issuers Order for
the authentication and delivery of such Securities, and the Trustee in
accordance with the Issuers Order shall authenticate and deliver such
Securities. If the form or terms of the Securities of the series have been
established in or pursuant to one or more Committee Resolutions and Board
Resolutions as permitted by Sections 201 and 301, or by one or more indentures
supplemental hereto as provided by Section 901, in authenticating such
Securities, and accepting the additional responsibilities under this Indenture
in relation to such Securities, the Trustee shall be entitled to receive, and
(subject to Section 601) shall be fully protected in relying upon, an Opinion of
Counsel stating,

                                      -18-

<PAGE>

               (1) that such form has been established in conformity with the
         provisions of this Indenture;

               (2) that such terms have been established in conformity with the
         provisions of this Indenture;

               (3) that this Indenture and such Securities, when authenticated
         and delivered by the Trustee and issued by the Issuers in the manner
         and subject to any conditions specified in such Opinion of Counsel,
         will constitute valid and legally binding obligations of the Issuers,
         enforceable in accordance with their terms, subject to bankruptcy,
         insolvency, fraudulent conveyance, reorganization and other laws of
         general applicability relating to or affecting the enforcement of
         creditors' rights and to general equity principles;

               (4) that all laws and requirements in respect of the execution
         and delivery by the Issuers of the Securities have been complied with;
         and

               (5) such other matters as the Trustee may reasonably request.

         If such form or terms have been so established, the Trustee shall not
be required to authenticate such Securities if the issue of such Securities
pursuant to this Indenture will affect the Trustee's own rights, duties or
immunities under the Securities and this Indenture or otherwise in a manner
which is not reasonably acceptable to the Trustee.

         Each Security shall be dated the date of its authentication unless
otherwise provided by the terms established and contemplated by Section 301.

         No Security shall be entitled to any benefit under this Indenture or be
valid or obligatory for any purpose unless there appears on such Security a
certificate of authentication substantially in the form provided for herein
executed by the Trustee by manual signature, and such certificate upon any
Security shall be conclusive evidence, and the only evidence, that such Security
has been duly authenticated and delivered hereunder and is entitled to the
benefits of this Indenture.

SECTION 304.      Temporary Securities.

         Pending the preparation of definitive Securities of any series, the
Issuers may execute, and upon Issuers Order the Trustee shall authenticate and
deliver, temporary Securities which are printed, lithographed, typewritten,
mimeographed or otherwise produced, in any authorized denomination,
substantially of the tenor of the definitive Securities in lieu of which they
are issued and with such appropriate insertions, omissions, substitutions and
other variations as the officers executing such Securities may determine, as
evidenced by their execution of such Securities.

         If temporary Securities of any series are issued, the Issuers will
cause definitive Securities of that series to be prepared without unreasonable
delay. After the preparation of definitive Securities of such series, the
temporary Securities of such series shall be exchangeable for definitive
Securities of such series upon surrender of the temporary Securities of such
series at the office or agency of the Issuers in a

                                      -19-

<PAGE>

Place of Payment for that series, without charge to the Holder. Upon surrender
for cancellation of any one or more temporary Securities of any series the
Issuers shall execute and the Trustee shall authenticate and deliver in exchange
therefor a like principal amount of definitive Securities of the same series of
authorized denominations and the Guarantor shall execute Guarantees thereon.
Until so exchanged the temporary Securities of any series shall in all respects
be entitled to the same benefits under this Indenture as definitive Securities
of such series.

SECTION 305.      Registration, Registration of Transfer and Exchange.

         The Issuers shall cause to be kept at one of their offices or agencies
maintained pursuant to Section 1002 or at the Corporate Trust Office of the
Trustee a register (the register maintained in such office and in any other
office or agency of the Issuers in a Place of Payment being herein sometimes
collectively referred to as the "Security Register") in which, subject to
Section 203 and to such reasonable regulations as it may prescribe, the Issuers
shall provide for the registration of Securities and of transfers of Securities.
The Trustee initially is hereby appointed "Security Registrar" for the purpose
of registering Securities and transfers of Securities as herein provided. The
Issuers may act as Security Registrar and may change or appoint a Security
Registrar without prior notice to Holders or to the Trustee.

         Subject to Section 203, upon surrender for registration of transfer of
any Security of any series at the office or agency in a Place of Payment for
that series, the Issuers shall execute, the Guarantor shall execute Guarantees
on, and the Trustee shall authenticate and deliver, in the name of the
designated transferee or transferees, one or more new Securities of the same
series, of any authorized denominations and of a like aggregate principal amount
and tenor.

         Subject to Section 203, at the option of the Holder, Securities of any
series may be exchanged for other Securities of the same series, of any
authorized denominations and of a like aggregate principal amount and tenor,
upon surrender of the Securities to be exchanged at such office or agency.
Whenever any Securities are so surrendered for exchange, the Issuers shall
execute, the Guarantor shall execute Guarantees on, and the Trustee shall
authenticate and deliver, the Securities which the Holder making the exchange is
entitled to receive.

         Subject to Section 203, all Securities issued upon any registration or
transfer or exchange of Securities and the Guarantees thereon shall be valid
obligations of the Issuers and the Guarantor, respectively, evidencing the same
debt, and entitled to the same benefits under this Indenture, as the Securities
surrendered upon such registration of transfer or exchange.

         Every Security presented or surrendered for registration of transfer or
for exchange shall (if so required by the Issuers or the Trustee) be duly
endorsed, or be accompanied by a written instrument of transfer in form
satisfactory to the Issuers and the Security Registrar duly executed, by the
Holder thereof or his attorney duly authorized in writing.

         No service charge shall be made for any registration of transfer or
exchange of Securities, but the Issuers may require payment of a sum sufficient
to cover any tax or other governmental charge that may be imposed in connection
with any registration of transfer or exchange of Securities, other than
exchanges pursuant to Section 203, 304, 906 or 1107 not involving any transfer.

                                      -20-

<PAGE>

         The Issuers shall not be required (i) to issue, register the transfer
of or exchange Securities of any series during a period beginning at the opening
of business 15 days before the day of the mailing of a notice of redemption of
Securities of that series selected for redemption (under Section 1103) and
ending at the close of business on the day of such mailing, or (ii) to register
the transfer of or exchange any Security so selected for redemption in whole or
in part, except the unredeemed portion of any Security being redeemed in part.

SECTION 306.      Mutilated, Destroyed, Lost and Stolen Securities.

         If there shall be delivered to the Trustee (i)(A) any mutilated
Security or (B) evidence to their satisfaction of the destruction, loss or theft
of any Security and (ii) such security or indemnity as may be required by them
to hold each of them and any agent of either of them harmless, then, in the
absence of notice to the Issuers or the Trustee that such Security has been
acquired by a bona fide purchaser, the Issuers shall execute and upon their
request the Trustee shall authenticate and deliver, in lieu of any such
destroyed, lost or stolen Security or in exchange for such mutilated Security, a
new Security of the same series and of like tenor and principal amount and
bearing a number not contemporaneously outstanding.

         In case any such mutilated, destroyed, lost or stolen Security has
become or is about to become due and payable, the Issuers in their discretion
may, instead of issuing a new Security, pay such Security.

         Upon the issuance of any new Security under this Section, the Issuers
may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in relation thereto and any other
expenses (including the fees and expenses of the Trustee) connected therewith.

         Every new Security of any series issued pursuant to this Section in
lieu of any destroyed, lost or stolen Security or in exchange for such mutilated
Security, shall constitute an original additional contractual obligation of the
Issuers, whether or not the mutilated, destroyed, lost or stolen Security shall
be at any time enforceable by anyone, and shall be entitled to all the benefits
of this Indenture equally and proportionately with any and all other Securities
of that series and the Guarantee duly issued hereunder.

         The provisions of this Section are exclusive and shall preclude (to the
extent lawful) all other rights and remedies with respect to the replacement or
payment of mutilated, destroyed, lost or stolen Securities.

SECTION 307.      Payment of Interest; Interest Rights Preserved.

         Interest on any Security which is payable, and is punctually paid or
duly provided for, on any Interest Payment Date shall be paid to the Person in
whose name that Security (or one or more Predecessor Securities) is registered
at the close of business on the Regular Record Date for such interest.

         Any interest on any Security of any series which is payable, but is not
punctually paid or duly provided for, on any Interest Payment Date (herein
called "Defaulted Interest") shall forthwith cease to be payable to the Holder
on the relevant Regular Record Date by virtue of having been such Holder, and
such Defaulted Interest may be paid by the Issuers or the Guarantor, at their or
its election in each case, as provided in clause (1) or (2) below:

               (1) The Issuers or the Guarantor may elect to make payment of any
         Defaulted Interest to the Persons in whose names the Securities of such
         series (or their respective Predecessor Securities) are registered at
         the close of business on a Special Record Date for the payment of such
         Defaulted Interest, which shall be fixed in the following manner. The
         Issuers or the Guarantor shall notify the Trustee in writing of the
         amount of Defaulted Interest proposed to be paid on each Security of
         such series and the date of the proposed payment, and at the same time
         the Issuers or the Guarantor shall deposit with the Trustee an amount
         of money equal to the aggregate amount proposed to be paid in respect
         of such Defaulted Interest or shall make arrangements satisfactory to
         the Trustee for such deposit prior to the date of the proposed payment,
         such money when deposited to be held in trust for the benefit of the
         Persons entitled to such Defaulted Interest as in this clause provided.
         Thereupon the Trustee shall fix a Special Record Date for the payment
         of such Defaulted Interest which shall be not more than 15 days and not
         less than 10 days prior to the date of the proposed payment and not
         less than 10 days after the receipt by the Trustee of the notice of the
         proposed payment. The Trustee shall promptly notify the Issuers and the
         Guarantor of such Special Record Date and, in the name and at the
         expense of the Issuers or the Guarantor, shall cause notice of the
         proposed payment of such Defaulted Interest and the Special Record Date
         therefor to be mailed, first-class postage prepaid, to each Holder of
         Securities of such series at his address as it appears in the Security
         Register, not less than 10 days prior to such Special Record Date.
         Notice of the proposed payment of such Defaulted Interest and the
         Special Record Date therefor having been so mailed, such Defaulted
         Interest shall be paid to the Persons in whose names the Securities of
         such series (or their respective Predecessor Securities) are registered
         at the close of business on such Special Record Date and shall no
         longer be payable pursuant to the following clause (2).

               (2) The Issuers or the Guarantor may make payment of any
         Defaulted Interest on the Securities of any series in any other lawful
         manner not inconsistent with the requirements of any securities
         exchange on which such Securities may be listed, and upon such notice
         as may be required by such exchange, if, after notice given by the
         Issuers or the Guarantor to the Trustee of the proposed payment
         pursuant to this clause, such manner of payment shall be deemed
         practicable by the Trustee.

         Subject to the foregoing provisions of this Section, each Security
lawfully delivered under this Indenture upon registration of transfer of or in
exchange for or in lieu of any other Security shall carry the rights to interest
accrued and unpaid, and to accrue, which were carried by such other Security.

SECTION 308.      Persons Deemed Owners.

         Subject to Section 203, the Issuers, the Guarantor, the Trustee and any
agent of the Issuers, the Guarantor or the Trustee may treat the Person in whose
name such Security is registered as the owner of such Security for the purpose
of receiving payment of principal of (and premium, if any) and (subject to
Section 307) interest on such Security and for all other purposes whatsoever,
whether or not such Security be overdue, and none of the Issuers, the Guarantor,
the Trustee or any agent of the Issuers, the Guarantor or the Trustee shall be
affected by notice to the contrary.

SECTION 309.      Cancellation.

         All Securities surrendered for payment, redemption, registration of
transfer or exchange or for credit against any sinking fund payment shall, if
surrendered to any Person other than the Trustee, be delivered to the Trustee
and shall be promptly cancelled by it. The Issuers or the Guarantor may at any
time deliver to the Trustee for cancellation any Securities previously
authenticated and delivered hereunder which the Issuers or the Guarantor may
have acquired in any manner whatsoever, and all Securities so delivered shall be
promptly cancelled by the Trustee. No Securities shall be authenticated in lieu
of or in exchange for any Securities cancelled as provided in this Section,
except as expressly permitted by this Indenture. The Trustee shall destroy
cancelled Securities and deliver a certificate of such destruction to the
Issuers or the Guarantor.

SECTION 310.      Computation of Interest.

         Except as otherwise specified as contemplated by Section 301 for the
Securities of any series, interest on the Securities of each series shall be
computed on the basis of a year of 12 30-day months.

SECTION 401.      Satisfaction and Discharge of Indenture.

         This Indenture shall upon the Issuers Request and the Guarantor Request
cease to be of further effect with respect to any series of Securities (except
as to (i) surviving rights of registration of transfer or exchange of Securities
expressly provided for, (ii) rights hereunder of Holders to receive payments of
principal of, and premium, if any, and interest on, Securities, and other
rights, duties and obligations of the Holders as beneficiaries hereof with
respect to the amounts, if any, so deposited with the Trustee, (iii) remaining
obligations of the Issuers to make mandatory sinking fund payments and (iv) the

                series which have been mutilated, destroyed, lost or stolen and
                which have been replaced or paid as provided in Section 306 and
                (ii) Securities of such series for whose payment money has
                theretofore been deposited in trust or segregated and held in
                trust by the Issuers or the Guarantor and thereafter repaid to
                the Issuers or the Guarantor or discharged from such trust, as
                provided in Section 1003) have been delivered to the Trustee for
                cancellation; or

                       (B) all such Securities not theretofore delivered to the
                Trustee for cancellation

                           (i) have become due and payable ; or

<PAGE>

                           (ii) will become due and payable at their Stated
                           Maturity within one year; or

                           (iii) are to be called for redemption within one year
                           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 or the
                           Guarantor,

         and the Issuers or the Guarantor in the case of (i), (ii) or (iii)
         above, have irrevocably deposited or caused to be deposited with the
         Trustee as trust funds in trust for such purpose an amount sufficient
         to pay and discharge the entire indebtedness on such Securities not
         theretofore delivered to the Trustee for cancellation, for principal of
         (and premium, if any) and interest to the date of such deposit (in the
         case of Securities which have become due and payable) or to the Stated
         Maturity or Redemption Date, as the case may be;

               (2) if all series of Securities are being discharged, the Issuers
         or the Guarantor have paid or caused to be paid all other sums payable
         hereunder by the Issuers or the Guarantor; and

               (3) the Issuers and the Guarantor have delivered to the Trustee
         an Officers' Certificate and an Opinion of Counsel, each stating that
         all conditions precedent herein provided for relating to the

         Notwithstanding the satisfaction and discharge of this Indenture, the
obligations of the Issuers and the Guarantor to the Trustee under Section 607
and, if money shall have been deposited with the Trustee pursuant to subclause
(B) of clause (1) of this Section, the obligations of the Trustee under Section
402 and the next to last paragraph of Section 1003 shall survive any such
satisfaction and discharge.

SECTION 402.      Application of Trust Funds; Indemnification.

         (a) Subject to the provisions of the next to last paragraph of Section
1003, all money deposited with the Trustee pursuant to Section 401, all money
and U.S. Government Obligations deposited with the Trustee pursuant to Section
403 or 404 and all money received by the Trustee in respect of U.S. Government
Obligations deposited with the Trustee pursuant to Section 403 or 404 shall be
held in trust and applied by it, in accordance with the provisions of the
Securities and this Indenture, to the payment, either directly or through any
Paying Agent (including the Issuers or the Guarantor acting as Paying Agent) as
the Trustee may determine, to the Persons entitled thereto, of the principal
(and premium, if any) and interest for whose payment such money has been
deposited with or received by the Trustee or to make mandatory sinking fund
payments or analogous payments as contemplated by Section 403 or 404, but such
money need not be segregated from other funds except to the extent required by
law.

         (b) The Issuers or the Guarantor shall pay and shall indemnify the
Trustee against any tax, fee or other charge imposed on or assessed against U.S.
Government Obligations deposited pursuant to Section 403 or 404, or the interest
and principal received in respect of such obligations other than any payable by
or on behalf of Holders.

from time to time upon Issuers Request or Guarantor Request any U.S. Government
Obligations or money held by it as provided in Section 403 or 404 which, in the
opinion of a nationally recognized firm of independent public accountants
expressed in a written certification thereof delivered to the Trustee, are then
in excess of the amount thereof which then would have been required to be
deposited for the purpose for which such obligations or money were deposited or
received.

SECTION 403.      Defeasance and Discharge of Indenture.

         The Issuers and the Guarantor shall be deemed to have paid and
discharged the entire indebtedness on all the Outstanding Securities on the 91st
day after the date of the deposit referred to in subparagraph (d) of this
Section, and the provisions of this Indenture, as it relates to such Outstanding
Securities, shall no longer be in effect (and the Trustee, at the expense of the
Issuers or the Guarantor, shall at Issuers Request or Guarantor Request, execute
proper instruments acknowledging the same), except as to:

         (a) the rights of Holders of Securities to receive, from the trust
funds described in subparagraph (d) hereof, (i) payment of the principal of (and
premium, if any) and each installment of principal of (and premium, if any) or
interest on the Outstanding Securities on the Stated Maturity of such principal
or installment of principal or interest and (ii) the benefit of any mandatory
sinking fund payments applicable to the Securities on the day on which such
payments are due and payable in accordance with the terms of this Indenture and
the Securities;

         (b) the Issuers' and the Guarantor's obligations with respect to such
Securities under Sections 305, 306, 1002 and 1003; and

         (c) the obligations of the Issuers and the Guarantor to the Trustee

         deposited (except as provided in Section 402) with the Trustee as trust
         funds in trust, specifically pledged as security for, and dedicated
         solely to, the benefit of the Holders of the Securities, (i) money in
         an amount, or (ii) U.S. Government Obligations which through the
         payment of interest and principal in respect thereof in accordance with
         their terms will provide not later than one day before the due date of
         any payment referred to in clause (A) or (B) of this subparagraph money
         in an amount, or (iii) a combination thereof, sufficient, in the
         opinion of a nationally recognized firm of independent certified public
         accountants expressed in a written certification thereof delivered to
         the Trustee, to pay and discharge (A) the principal of (and premium, if
         any) and each installment of principal of (and premium, if any) and
         interest on the Outstanding Securities on the Stated Maturity of such
         principal or installment of principal or interest or on the applicable
         Redemption Date and (B) any mandatory sinking fund payments applicable
         to the Securities on the day on which such payments are due and payable
         in accordance with the terms of this Indenture and of the Securities;

                                      -25-

<PAGE>

               (2) such deposit shall not cause the Trustee with respect to the
         Securities to have a conflicting interest for purposes of the Trust
         Indenture Act with respect to the Securities;

               (3) such deposit will not result in a breach or violation of, or
         constitute a default under, any applicable laws, this Indenture or any
         other agreement or instrument to which the Issuers or the Guarantor are
         a party or by which they are bound;

               (4) no Event of Default or event which with notice or lapse of
         time would become an Event of Default with respect to the Securities
         shall have occurred and be continuing on the date of such deposit or
         during the period ending on the 91st day after such date;

               (5) if the deposit referred to in subparagraph (d) of this
         Section is to be made on or prior to one year from the Stated Maturity
         for payment of principal of the Outstanding Securities, the Issuers and
         the Guarantor have delivered to the Trustee an Opinion of Counsel with
         no material qualifications or a favorable ruling of the Internal
         Revenue Service, in either case to the effect that Holders of the
         Securities will not recognize income, gain or loss for federal income
         tax purposes as a result of such deposit, defeasance and discharge and
         will be subject to federal income tax on the same amount and in the
         same manner and at the same times, as would have been the case if such
         deposit, defeasance and discharge had not occurred.

SECTION 404.      Defeasance of Certain Obligations.

         If this Section is specified to be applicable to Securities of any
series, the Issuers or the Guarantor may omit to comply with (or elect to have
the obligations of the Guarantor released with respect to) any term, provision
or condition set forth in the Sections of this Indenture or such Security with
respect to the Securities of that series ("Covenant Defeasance") if:

               (1) with reference to this Section, the Issuers or the Guarantor
         have deposited or caused to be irrevocably deposited with the Trustee
         as trust funds in trust, specifically pledged as security for, and
         dedicated solely to, the benefit of the Holders of the Securities of
         that series, (i) money in an amount, or (ii) U.S. Government
         Obligations which through the payment of interest and principal in
         respect thereof in accordance with their terms will provide not later
         than one day before the due date of any payment referred to in clause
         (A) or (B) of this subparagraph money in an amount, or (iii) a
         combination thereof, sufficient, in the opinion of a nationally
         recognized firm of independent public accountants expressed in a
         written certification thereof delivered to the Trustee, to pay and
         discharge (A) the principal of (and premium, if any) and each
         installment of principal (and premium, if any) and interest on the
         Outstanding Securities of that series on the Stated Maturity of such
         principal or installment of principal or interest and (B) any mandatory
         sinking fund payments or analogous payments applicable to Securities of
         such series on the day on which such payments are due and payable in
         accordance with the terms of the Indenture and of such Securities;

               (2) such deposit shall not cause the Trustee with respect to the
         Securities of that series to have a conflicting interest for purposes
         of the Trust Indenture Act with respect to the Securities of any
         series;

                                      -26-

<PAGE>

               (3) such deposit will not result in a breach or violation of, or
         constitute a default under, this Indenture or any other agreement or
         instrument to which the Issuers or the Guarantor are parties or a party
         or by which they or it are bound;

               (4) if the deposit referred to in subparagraph (1) of this
         Section is to be made on or prior to one year from the Stated Maturity
         for payment of principal of the Outstanding Securities, the Issuers and
         the Guarantor have delivered to the Trustee an Opinion of Counsel with
         no material qualifications or a favorable ruling of the Internal
         Revenue Service, in either case to the effect that Holders of the
         Securities will not recognize income, gain or loss for federal income
         tax purposes as a result of such deposit and defeasance of certain
         obligations and will be subject to federal income tax on the same
         amount and in the same manner and at the same times, as would have been
         the case if such deposit and defeasance had not occurred; and

               (5) the Issuers and the Guarantor have delivered to the Trustee
         an Officers' Certificate and an Opinion of Counsel, each stating that
         all conditions precedent herein provided for relating to the defeasance
         contemplated by this Section have been complied with.

         In the event the Issuers or the Guarantor effect Covenant Defeasance
with respect to any Securities and such Securities are declared due and payable
because of the occurrence of any Event of Default, other than an Event of
Default with respect to any covenant as to which there has been Covenant
Defeasance, the U.S. Government Obligations on deposit with the Trustee will be
sufficient to pay amounts due on such Securities at the time of the Stated
Maturity but may not be sufficient to pay amounts due on such Securities at the
time of the acceleration resulting from such Event of Default.

         covenant or warranty of the Issuers or the Guarantor in this Indenture
         (other than a covenant or warranty a default in whose performance or

         (A) a decree or order for relief in respect of either of the Issuers or
         the Guarantor in an involuntary case or proceeding under any applicable
         bankruptcy, insolvency, reorganization or other similar law or (B) a
         decree or order adjudging either of the Issuers or the Guarantor a
         bankrupt or insolvent, or approving as properly filed a petition
         seeking reorganization, arrangement, adjustment or composition of or in
         respect of either of the Issuers or the Guarantor under any applicable
         law, or appointing a custodian, receiver, liquidator, assignee,

         law or to the commencement of any bankruptcy or insolvency case or
         proceeding against it, or the filing by it of a petition or answer or
         consent seeking reorganization or relief under any applicable law, or
         the consent by it to the filing of such petition or to the appointment
         of or taking possession by a custodian, receiver, liquidator, assignee,
         trustee, sequestrator or similar official of either of the Issuers or
         of any substantial part of its property, or the making by it of an
         assignment for the benefit of creditors, or the admission by it in
         writing of its inability to pay its debts generally as they become due
         and its willingness to have a case commenced against it or to seek an
         order for relief under any applicable bankruptcy, insolvency or other
         similar law or the taking of corporate action by either of the Issuers
         or the Guarantor in furtherance of any such action;

               (6) the Guarantee ceases to be in full force and effect or is
         declared to be null and void and unenforceable or is found to be
         invalid, in each case by a court of competent jurisdiction in a final
         non-appealable judgment, or the Guarantor denies its liability under
         the Guarantee (other than by reason of release of the Guarantor in
         accordance with the terms of this Indenture); or

               (7) any other Event of Default expressly provided with respect to
         Securities of that series.

SECTION 502.      Acceleration of Maturity; Rescission and Annulment.

         If an Event of Default (other than by reason of an Event of Default
specified in clause (4) or (5) of Section 501) with respect to Securities of any
series at the time Outstanding occurs and is continuing,

                                      -28-

<PAGE>

then in every such case the Trustee or the Holders of not less than 25% in
principal amount of the Outstanding Securities of that series may declare the
unpaid principal of and accrued interest to the date of acceleration on (or, if
the Securities of that series are Original Issue Discount Securities, such
portion of the principal amount as may be specified in the terms of that series)
all of the Securities of that series to be due and payable immediately, by a
notice in writing to the Issuers and the Guarantor (and to the Trustee if given
by Holders), and upon any such declaration, such unpaid principal and accrued
interest (or specified principal amount) shall become immediately due and
payable.

         If an Event of Default specified in clause (4) or (5) of Section 501
with respect to Securities of any series at the time Outstanding occurs and is
continuing, then all unpaid principal of and accrued interest on the Outstanding
Securities of that series (or specified principal amount) shall become
immediately due and payable without any notice or other action on the part of
the Trustee or the Holders of the Securities of such series.

         At any time after such a declaration of acceleration with respect to
Securities of any series has been made and before a judgment or decree for
payment of the money due has been obtained by the Trustee as hereinafter in this
Article provided, the Holders of a majority in principal amount of the
Outstanding Securities of that series, by written notice to the Issuers, the
Guarantor and the Trustee, may rescind and annul such declaration and its
consequences if

               (1) the Issuers or the Guarantor have paid or deposited with the
         Trustee a sum sufficient to pay

                    (A) all overdue interest on all Securities of that series,

                    (B) the principal of (and premium, if any, on) any
               Securities of that series which have become due otherwise than by
               such declaration of acceleration and interest thereon at the rate
               or rates prescribed therefor in such Securities,

                    (C) to the extent that payment of such interest is lawful,
               interest upon overdue interest at the rate or rates prescribed
               therefor in such Securities, and

                    (D) all sums paid or advanced by the Trustee and any
               predecessor Trustee hereunder and all sums due the Trustee and
               any predecessor Trustee under Section 607;

             and

               (2) all Events of Default with respect to Securities of that
         series, other than the non-payment of the principal of Securities of
         that series which have become due solely by such declaration of
         acceleration, have been cured or waived as provided in Section 513.

         No such rescission shall affect any subsequent default or impair any
right consequent thereon.

                                      -29-

SECTION 503.      Collection of Indebtedness and Suits for Enforcement by
                  Trustee.

         The Issuers and the Guarantor covenant that if

               (1) default is made in the payment of any interest on any
         Security when such interest becomes due and payable and such default
         continues for a period of 30 days, or

               (2) default is made in the payment of the principal of (or
         premium, if any, on) any Security at the Maturity thereof,

the Issuers or the Guarantor will, upon demand of the Trustee, pay to it, for
the benefit of the Holders of such Securities, the whole amount then due and
payable on such Securities for principal (and premium, if any) and interest and,
to the extent that payment of such interest shall be legally enforceable,
interest on any overdue principal (and premium, if any) and on any overdue
interest, at the rate or rates prescribed therefor in such Securities, and, in
addition thereto, such further amount as shall be sufficient to cover the costs
and expenses of collection, including all amounts due the Trustee and any
predecessor Trustee under Section 607.

         If the Issuers or the Guarantor fail to pay such amounts forthwith upon
such demand, the Trustee, in its own name and as trustee of an express trust,
may institute a judicial proceeding for the collection of the sums so due and
unpaid, may prosecute such proceeding to judgment or final decree and may
enforce the same against the Issuers or the Guarantor or any other obligor upon
such Securities and collect the moneys adjudged or decreed to be payable in the
manner provided by law out of the property of the Issuers or the Guarantor or
any other obligor upon such Securities, wherever situated.

         If any Event of Default with respect to Securities of any series occurs
and is continuing, the Trustee may in its discretion proceed to protect and
enforce its rights and the rights of the Holders of Securities of such series by
such appropriate judicial proceedings as the Trustee shall deem most effectual
to protect and enforce any such rights, whether for the specific enforcement of
any covenant or agreement in this Indenture or in aid of the exercise of any
power granted herein, or to enforce any other proper remedy.

SECTION 504.      Trustee May File Proofs of Claim.

         In case of the pendency of any receivership, insolvency, liquidation,
bankruptcy, reorganization, arrangement, adjustment, composition or other
judicial proceeding relative to either of the Issuers or the Guarantor or any
other obligor, upon the Securities or the property of either of the Issuers or
the Guarantor or of such other obligor or their creditors, the Trustee
(irrespective of whether the principal of the Securities shall then be due and
payable as therein expressed or by declaration or otherwise and irrespective of
whether the Trustee shall have made any demand on the Issuers or the Guarantor
for the payment of overdue principal, premium, if any, or interest) shall be
entitled and empowered, by intervention in such proceeding or otherwise,

               (1) to file and prove a claim for the whole amount of principal
         (and premium, if any), interest owing and unpaid in respect of the
         Securities and to file such other papers or documents as

                                      -30-

<PAGE>

         may deem 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
         of the Holders allowed in such judicial proceeding, and

               (2) to collect and receive any moneys or other property payable
         or deliverable on any such claims and to distribute the same;

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or
other similar official 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 the Trustee any amount due 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 607.

         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 Securities
or the rights of any Holder thereof, or to authorize the Trustee to vote in
respect of the claim of any Holder in any such proceeding.

SECTION 505.      Trustee May Enforce Claims Without Possession of Securities.

         All rights of action and claims under this Indenture or the Securities
may be prosecuted and enforced by the Trustee without the possession of any of
the Securities or the production thereof in any proceeding relating thereto, and
any such proceeding instituted by the Trustee shall be brought in its own name
and as trustee of an express trust, and any recovery of judgment shall, after
provision for the payment of the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, be for the
ratable benefit of the Holders of the Securities in respect of which such
judgment has been recovered.

SECTION 506.      Application of Money Collected.

         Any money collected by the Trustee pursuant to this Article shall be
applied in the following order, at the date or dates fixed by the Trustee and,
in case of the distribution of such money on account of principal (or premium,
if any) or interest, upon presentation of the Securities and the notation
thereon of the payment if only partially paid and upon surrender thereof if
fully paid:

                  FIRST: To the payment of all amounts due the Trustee and each
         predecessor Trustee under Section 607;

                  SECOND: To the payment of the amounts then due and unpaid for
         principal of (and premium, if any) and interest on the Securities in
         respect of which or for the benefit of which such money has been
         collected, ratably, without preference or priority of any kind,
         according to the amounts due and payable on such Securities for
         principal (and premium, if any), and interest, respectively; and

                  THIRD:  To the Issuers.

                                      -31-

SECTION 507.      Limitation on Suits.

         No Holder of any Security of any series shall have any right to
institute any proceeding, judicial or otherwise, with respect to this Indenture,
or for the appointment of a receiver or trustee, or for any other remedy
hereunder, unless:

               (1) such Holder has previously given written notice to the
         Trustee of a continuing Event of Default with respect to the Securities
         of that series;

               (2) the Holders of not less than 25% in principal amount of the
         Outstanding Securities of that series shall have made written request
         to the Trustee to institute proceedings in respect of such Event of
         Default in its own name as Trustee hereunder;

               (3) such Holder or Holders have offered to the Trustee reasonable
         indemnity against the costs, expenses and liabilities to be incurred in
         compliance with such request;

               (4) the Trustee for 60 days after its receipt of such notice,
         request and offer of indemnity has failed to institute any such
         proceeding; and

               (5) no direction inconsistent with such written request has been
         given to the Trustee during such 60-day period by the Holders of a
         majority in principal amount of the Outstanding Securities of that
         series;

it being understood and intended that no one or more of such Holders shall have
any right in any manner whatever by virtue of, or by availing of, any provision
of this Indenture to affect, disturb or prejudice the rights of any other of
such Holders, or to obtain or to seek to obtain priority or preference over any
other of such Holders or to enforce any right under this Indenture, except in
the manner herein provided and for the equal and ratable benefit of all such
Holders.

SECTION 508.      Unconditional Right of Holders to Receive Principal, Premium
                  and Interest.

         Notwithstanding any other provision in this Indenture, the Holder of
any Security shall have the right, which is absolute and unconditional, to
receive payment of the principal of (and premium, if any) and (subject to
Section 307) interest on such Security or the Guarantee on the Stated Maturity
or Maturities expressed in such Security (or, in the case of redemption, on the
Redemption Date) and to institute suit for the enforcement of any such payment,
and such rights shall not be impaired without the consent of such Holder.

SECTION 509.      Restoration of Rights and Remedies.

         If the Trustee or any Holder has instituted any proceeding to enforce
any right or remedy under this Indenture or the Guarantee and such proceeding
has been discontinued or abandoned for any reason, or has been determined
adversely to the Trustee or to such Holder, then and in every such case, subject
to any determination in such proceeding, the Issuers, the Guarantor, the Trustee
and the Holders shall be

                                      -32-

<PAGE>

restored severally and respectively to their former positions hereunder and
thereafter all rights and remedies of the Trustee and the Holders shall continue
as though no such proceeding had been instituted.

SECTION 510.      Rights and Remedies Cumulative.

         Except as otherwise provided with respect to the replacement or payment
of mutilated, destroyed, lost or stolen Securities in the last paragraph of
Section 306, no right or remedy herein or in the Guarantee conferred upon or
reserved to the Trustee or to the Holders is intended to be exclusive of any
other right or remedy, and every right and remedy shall, to the extent permitted
by law, be cumulative and in addition to every other right and remedy given
hereunder or now or hereafter existing at law or in equity or otherwise. The
assertion or employment of any right or remedy hereunder, or otherwise, shall
not prevent the concurrent assertion or employment of any other appropriate
right or remedy.

SECTION 511.      Delay or Omission Not Waiver.

         No delay or omission of the Trustee or of any Holder of any Securities
to exercise any right or remedy accruing upon any Event of Default shall impair
any such right or remedy or constitute a waiver of any such Event of Default or
any acquiescence therein. Every right and remedy given by this Article or by law
to the Trustee or to the Holders may be exercised from time to time, and as
often as may be deemed expedient, by the Trustee or by the Holders, as the case
may be.

SECTION 512.      Control by Holders.

         The Holders of a majority in principal amount of the Outstanding
Securities of any series (or if more than one series is affected thereby, of all
series so affected, voting as a single class) shall have the right to direct the
time, method and place of conducting any proceeding for any remedy available to
the Trustee, or exercising any trust or power conferred on the Trustee, with
respect to the Securities of such series, provided that

               (1) such direction shall not be in conflict with any rule of law
         or with this Indenture, expose the Trustee to personal liability or be
         unduly prejudicial to holders not joining therein, and

               (2) the Trustee may take any other action deemed proper by the
         Trustee which is not inconsistent with such direction.

         Nothing in this Indenture shall impair the right of the Trustee to take
any other action deemed proper by the Trustee which is not inconsistent with
such direction.

SECTION 513.      Waiver of Past Defaults.

         The Holders of not less than a majority in principal amount of the
Outstanding Securities of any series may on behalf of the Holders of all the
Securities of such series waive any past default hereunder with respect to such
series and its consequences, except a default

               (1) in the payment of the principal of (or premium, if any) or
         interest on any Security of such series, or

                                      -33-

<PAGE>

               (2) in respect of a covenant or provision hereof which under this
         Article cannot be modified or amended without the consent of the Holder
         of each Outstanding Security of such series affected.

         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 514.      Undertaking for Costs.

         All parties to this Indenture agree, and each Holder of any Security by
his acceptance thereof shall be deemed to have agreed, that any court may in its
discretion require, 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,
suffered or omitted by it as Trustee, the filing by any party litigant in such
suit of an undertaking to pay the costs of such suit, and that such court may in
its discretion assess reasonable costs, including reasonable attorneys' fees,
against any party litigant in such suit, having due regard to the merits and
good faith of the claims or defenses made by such party litigant; but the
provisions of this Section shall not apply to any suit instituted by the
Issuers, to any suit instituted by the Trustee, to any suit instituted by any
Holder, or group of Holders, holding in the aggregate more than 10% in principal
amount of the Outstanding Securities of any series, or to any suit instituted by
any Holder for the enforcement of the payment of the principal of (or premium,
if any) or interest on any Securities on or after the Stated Maturity or
Maturities expressed in such Security (or, in the case of redemption, on or
after the Redemption Date). This Section 514 shall be in lieu of Section 315(e)
of the Trust Indenture Act and such Section 315(e) is hereby expressly excluded
from this Indenture, as permitted by the Trust Indenture Act.

                                   ARTICLE SIX
                                   THE TRUSTEE

SECTION 601.      Certain Duties and Responsibilities.

         (a) Except during the continuance of an Event of Default with respect
to the Securities of any series,

               (1) the Trustee undertakes to perform such duties and only such
         duties as are specifically set forth in this Indenture with respect to
         such series, and no implied covenants or obligations shall be read into
         this Indenture against the Trustee; and

               (2) in the absence of bad faith on its part, the Trustee may
         conclusively rely, as to the truth of the statements and the
         correctness of the opinions expressed therein, upon certificates or
         opinions furnished to the Trustee and conforming to the requirements of
         this Indenture; but in the case of any such certificates or opinions
         which by any provision hereof are specifically required to be furnished
         to the Trustee, the Trustee shall be under a duty to examine the same
         to determine whether or not they conform to the requirements of this
         Indenture.

                                      -34-

<PAGE>

         (b) In case an Event of Default has occurred with respect to Securities
of any series and is continuing, the Trustee shall exercise such of the rights
and powers vested in it by this Indenture with respect to such series of
Securities, and use the same degree of care and skill in their exercise, as a
prudent man would exercise or use under the circumstances in the conduct of his
own affairs.

         (c) No provision of this Indenture shall be construed to relieve the
Trustee from liability for its own negligent action, its own negligent failure
to act, or its own willful misconduct, except that

               (1) this Subsection shall not be construed to limit the effect of
         Subsection (a) of this Section;

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

               (3) the Trustee shall not be liable with respect to any action
         taken or omitted to be taken by it in good faith in accordance with the
         direction of the Holders of a majority in principal amount of the
         Outstanding Securities of any series, determined as provided in Section
         512, relating to the time, method and place of conducting any
         proceeding for any remedy available to the Trustee, or exercising any
         trust or power conferred upon the Trustee, under this Indenture with
         respect to the Securities of such series; and

               (4) no provision of this Indenture shall require the Trustee to
         expend or risk its own funds or otherwise incur any financial liability
         in the performance of any of its duties hereunder, or in the exercise
         of any of its rights or powers, if it shall have reasonable grounds for
         believing that repayment of such funds or adequate indemnity against
         such risk or liability is not reasonably assured to it.

         (d) Whether or not therein expressly so provided, every provision of
this Indenture relating to the conduct or affecting the liability of or
affording protection to the Trustee shall be subject to the provisions of this
Section and to the Trust Indenture Act.

SECTION 602.      Notice of Defaults.

         Within 90 days after the occurrence of any default hereunder with
respect to the Securities of any series, the Trustee shall transmit by mail to
all Holders of Securities of such series, as their names and addresses appear in
the Security Register, notice of such default hereunder known to the Trustee,
unless such default shall have been cured or waived; provided, however, that,
except in the case of a default in the payment of the principal of (or premium,
if any) or interest on any Security of such series or in the payment of any
sinking fund installment with respect to Securities of such series, the Trustee
shall be protected in withholding such notice if and so long as the board of
directors, the executive committee or a trust committee of directors or
Responsible Officers of the Trustee in good faith determines that the
withholding of such notice is in the interest of the Holders of Securities of
such series; and provided, further, that in the case of any default of the
character specified in Section 501(3) with respect to Securities of such series,
no such notice to Holders shall be given until at least 30 days after the
occurrence thereof.

                                      -35-

For the purpose of this Section, the term "default" means any event which is, or
after notice or lapse of time or both would become, an Event of Default with
respect to Securities of such series.

SECTION 603.      Certain Rights of Trustee.

         Subject to the provisions of Section 601:

rely upon an Officers' Certificate;

         (d) the Trustee may consult with counsel and the advice of such counsel
or any Opinion of Counsel shall be full and complete authorization and

in good faith and in reliance thereon;

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

         (f) the Trustee shall not be bound to make any investigation into the
facts or matters stated in any resolution, certificate, statement, instrument,

Trustee, in its discretion, may make such further inquiry or investigation into
such facts or matters as it may see fit, and, if the Trustee shall determine to
make such further inquiry or investigation, it shall be entitled to examine the
books, records and premises of the Issuers, personally or by agent or attorney;
and

         (g) the Trustee may execute any of the trusts or powers hereunder or

SECTION 604.      Trustee Not Responsible for Recitals or Issuance of
                  Securities.

         The recitals contained herein and in the Securities, except the
Trustee's certificates of authentication, shall be taken as the statements of
the Issuers, and the Trustee assumes no responsibility for their correctness.
The Trustee makes no representations as to the validity or sufficiency of this
Indenture or of the Securities. The Trustee shall not be accountable for the use

612, may otherwise deal with, and collect obligations owed to it by, the Issuers
the Guarantor with the same rights it would have if it were not Trustee, Paying
Agent, Security Registrar or such other agent.

SECTION 606.      Money Held in Trust.

         Money held by the Trustee in trust hereunder need not be segregated

under no liability for interest on any money received by it hereunder except as
otherwise agreed with the Issuers and the Guarantor.

SECTION 607.      Compensation and Reimbursement.

         The Issuers and the Guarantor, jointly and severally, agree:

               (1) to pay to the Trustee from time to time reasonable
         compensation for all services rendered by it hereunder (which
         compensation shall not be limited by any provision of law in regard to
         the compensation of a trustee of an express trust);

               (2) except as otherwise expressly provided herein, to reimburse
         each of the Trustee and any predecessor Trustee upon its request for
         all reasonable expenses, disbursements and advances incurred or made by
         it in accordance with any provision of this Indenture (including the
         reasonable compensation and the expenses and disbursements of its
         agents and counsel), except any such expense, disbursement or advance
         as may be attributable to its own negligence or bad faith; and

               (3) to indemnify each of the Trustee and any predecessor Trustee
         for, and to hold it harmless against, any loss, liability or expense,
         arising out of or in connection with the acceptance or administration
         of the trust or trusts hereunder and the performance of its duties
         hereunder, including the costs and expenses of defending itself against
         any claim or liability in connection with the exercise or performance
         of any of its powers or duties hereunder, except to the extent any such
         loss, liability or expense is due to its own negligence or bad faith.

<PAGE>

         To ensure the performance of the obligations of the Issuers or the
Guarantor under this Section, the Trustee shall have a senior claim to which the
Securities are hereby made subordinate upon all property and funds held or
collected by the Trustee as such, except property and funds held in trust for
the payment of principal of, premium, if any, or interest on particular
Securities.

SECTION 608.      Disqualification; Conflicting Interests.

         Trustee shall comply with the terms of Section 310(b) of the Trust
Indenture Act. The provisions of Section 310 of the Trust Indenture Act shall
apply to the Issuers and the Guarantor as obligors of the Securities.

SECTION 609.      Corporate Trustee Required; Eligibility.

         There shall at all times be a Trustee hereunder which shall be a
corporation organized and doing business under the laws of the United States of
America, any State thereof or the District of Columbia, authorized under such
laws to exercise corporate trust powers having (or, in the case of the
subsidiary of a bank holding company that guarantees the obligations of the
Trustee under this Indenture, such holding company's parent shall have) a
combined capital and surplus of at least $50,000,000 subject to supervision or
examination by Federal or State authority. If such corporation or holding
company parent publishes reports of condition at least annually, pursuant to law
or the requirements of said supervising or examining authority, then for the
purposes of this Section, the combined capital and surplus of such corporation
or holding company parent shall be deemed to be its combined capital and surplus
as set forth in its most recent report of condition so published. If at any time
the Trustee shall cease to be eligible in accordance with the provisions of this
Section, it shall resign immediately in the manner and with the effect
hereinafter specified in this Article.

SECTION 610.      Resignation and Removal; Appointment of Successor.

         (a) No resignation or removal of the Trustee and no appointment of a
successor Trustee pursuant to this Article shall become effective until the
acceptance of appointment by the successor Trustee in accordance with the
applicable requirements of Section 611.

         (b) The Trustee may resign at any time with respect to the Securities
of one or more series by giving written notice thereof to the Issuers and the
Guarantor. If the instrument of acceptance by a successor Trustee required by
Section 611 shall not have been delivered to the Trustee within 30 days after
the giving of such notice of resignation, the resigning Trustee may petition any
court of competent jurisdiction for the appointment of a successor Trustee with
respect to the Securities of such series. If the acceptance of appointment is
substantially contemporaneous with the resignation, then the notice called for
by the first sentence of this Subsection may be combined with the instrument
called for by Section 611.

         (c) the Trustee may be removed at any time with respect to the
Securities of any series by Act of the Holders of a majority in principal amount
of the Outstanding Securities of such series delivered to the Trustee, the
Issuers and the Guarantor.

                                      -38-

<PAGE>

         (d) If at any time:

               (1) the Trustee shall fail to comply with Section 608 after
         written request therefor by the Issuers, the Guarantor or by any Holder
         who has been a bona fide Holder of a Security for at least six months,
         or

               (2) the Trustee shall cease to be eligible under Section 609 and
         shall fail to resign after written request therefor by the Issuers, the
         Guarantor or by any such Holder, or

               (3) the Trustee shall become incapable of acting or shall be
         adjudged a bankrupt or insolvent or a receiver of the Trustee or of its
         property shall be appointed or any public officer shall take charge or
         control of the Trustee or of its property or affairs for the purpose of
         rehabilitation, conservation or liquidation,

then, in any such case, (i) the Issuers or the Guarantor by a Committee
Resolution or a Board Resolution, as the case may be, may remove the Trustee
with respect to all Securities, or (ii) subject to Section 514, any Holder who
has been a bona fide Holder of a Security for at least six months may, on behalf
of himself and all others similarly situated, petition any court of competent
jurisdiction for the removal of the Trustee with respect to all Securities and
the appointment of a successor Trustee or Trustees.

         (e) If the Trustee shall resign, be removed or become incapable of
acting, or if a vacancy shall occur in the office of Trustee for any cause, with
respect to the Securities of one or more series, the Issuers or the Guarantor,
by a Committee Resolution or a Board Resolution, as the case may be, shall
promptly appoint a successor Trustee or Trustees with respect to the Securities
of that or those series (it being understood that any such successor Trustee may
be appointed with respect to the Securities of one or more or all of such series
and that at any time there shall be only one Trustee with respect to the
Securities of any particular series) and shall comply with the applicable
requirements of Section 611. If, within one year after such resignation, removal
or incapability, or the occurrence of such vacancy, a successor Trustee with
respect to the Securities of any series shall be appointed by Act of the Holders
of a majority in principal amount of the Outstanding Securities of such series
delivered to the Issuers, the Guarantor and the retiring Trustee, the successor
Trustee so appointed shall, forthwith upon its acceptance of such appointment in
accordance with the applicable requirements of Section 611, become the successor
Trustee with respect to the Securities of such series and to that extent
supersede the successor appointed by the Issuers or the Guarantor. If no
successor Trustee with respect to the Securities of any series shall have been
so appointed by the Issuers, the Guarantor or the Holders and accepted
appointment in the manner required by Section 611, any Holder who has been a
bona fide Holder of a Security of such series for at least six months may, on
behalf of himself and all others similarly situated, petition any court of
competent jurisdiction for the appointment of a successor Trustee with respect
to the Securities of such series.

         (f) The Issuers or the Guarantor shall give notice of each resignation
and each removal of the Trustee with respect to the Securities of any series and
each appointment of a successor Trustee with respect to the Securities of any
series by mailing written notice of such event by first-class mail, postage
prepaid, to all Holders of Securities of such series as their names and
addresses appear in the Security

                                      -39-

<PAGE>

Register. Each notice shall include the name of the successor Trustee with
respect to the Securities of such series and the address of its Corporate Trust
Office.

SECTION 611.      Acceptance of Appointment by Successor.

         (a) In case of the appointment hereunder of a successor Trustee with
respect to all Securities, every such successor Trustee so appointed shall
execute, acknowledge and deliver to the Issuers, the Guarantor and to the
retiring Trustee an instrument accepting such appointment, and thereupon the
resignation or removal of the retiring Trustee shall become effective and such
successor Trustee, without any further act, deed or conveyance, shall become
vested with all the rights, powers, trusts and duties of the retiring Trustee;
but, on the request of the Issuers, the Guarantor or the successor Trustee, such
retiring Trustee shall, upon payment of its charges, execute and deliver an
instrument transferring to such successor Trustee all the rights, powers and
trusts of the retiring Trustee and shall duly assign, transfer and deliver to
such successor Trustee all property and money held by such retiring Trustee
hereunder.

         (b) In case of the appointment hereunder of a successor Trustee with
respect to the Securities of one or more (but not all) series, the Issuers, the
Guarantor, the retiring Trustee and each successor Trustee with respect to the
Securities of one or more series shall execute and deliver an indenture
supplemental hereto wherein each successor Trustee shall accept such appointment
and which (1) shall contain such provisions as shall be necessary or desirable
to transfer and confirm to, and to vest in, each successor Trustee all the
rights, powers, trusts and duties of the retiring Trustee with respect to the
Securities of that or those series to which the appointment of such successor
Trustee relates, (2) if the retiring Trustee is not retiring with respect to all
Securities, shall contain such provisions as shall be deemed necessary or
desirable to confirm that all the rights, powers, trusts and duties of the
retiring Trustee with respect to the Securities of that or those series as to
which the retiring Trustee is not retiring shall continue to be vested in the
retiring Trustee, and (3) shall add to or change any of the provisions of this
Indenture as shall be necessary to provide for or facilitate the administration
of the trusts hereunder by more than one Trustee, it being understood that
nothing herein or in such supplemental indenture shall constitute such Trustees
co-trustees of the same trust and that each such Trustee shall be trustee of a
trust or trusts hereunder separate and apart from any trust or trusts hereunder
administered by any other such Trustee; and upon the execution and delivery of
such supplemental indenture the resignation or removal of the retiring Trustee
shall become effective to the extent provided therein and each such successor
Trustee, without any further act, deed or conveyance, shall become vested with
all the rights, powers, trusts and duties of the retiring Trustee with respect
to the Securities of that or those series to which the appointment of such
successor Trustee relates; but, on request of the Issuers, the Guarantor or any
successor Trustee, such retiring Trustee shall duly assign, transfer and deliver
to such successor Trustee all property and money held by such retiring Trustee
hereunder with respect to the Securities of that or those series to which the
appointment of such successor Trustee relates.

         (c) Upon request of any such successor Trustee, the Issuers and the
Guarantor shall execute any and all instruments for more fully and certainly
vesting in and confirming to such successor Trustee all such rights, powers and
trusts referred to in paragraph (a) or (b) of this Section, as the case may be.

         (d) No successor Trustee shall accept its appointment unless at the
time of such acceptance such successor Trustee shall be qualified and eligible
under this Article.

SECTION 612.      Merger, Conversion, Consolidation or Succession to Business.

         Any corporation into which the Trustee may be merged or converted or
with which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any
corporation succeeding to all or substantially all the corporate trust business
of the Trustee (including the administration of this Indenture), shall be the
successor of the Trustee hereunder, provided such corporation shall be otherwise
qualified and eligible under this Article, without the execution or filing of
any paper or any further act on the part of any of the parties hereto. In case
any Securities shall have been authenticated, but not delivered, by the Trustee
then in office, any successor by merger, conversion or consolidation to such
authenticating Trustee may adopt such authentication and deliver the Securities
so authenticated with the same effect as if such successor Trustee had itself
authenticated such Securities.

SECTION 613.      Preferential Collection of Claims Against Issuers.

         If and when the Trustee shall be or become a creditor of the Issuers or
the Guarantor (or any other obligor upon the Securities), the Trustee shall be
subject to the provisions of the Trust Indenture Act regarding the collection of
claims against the Issuers or the Guarantor (or any such other obligor). A
trustee who has resigned or been removed shall be subject to the Trust Indenture
Act Section 311(a) to the extent provided therein.

                HOLDERS LISTS AND REPORTS BY TRUSTEE AND ISSUERS

SECTION 701.      The Issuers to Furnish Trustee Names and Addresses.

         The Issuers will furnish or cause to be furnished to the Trustee with
respect to the Securities of each series

               (1) semi-annually, not more than fifteen days after each Regular
         Record Date, or, in the case of any series of Securities on which
         semi-annual interest is not payable, not more than fifteen days after
         such semi-annual dates as may be specified by the Trustee, a list, in
         such form as the Trustee may reasonably require, of the names and
         addresses of the Holders as of such Regular Record Date or such
         semi-annual date, as the case may be, and

               (2) at such other times as the Trustee may request in writing,
         within 30 days after the receipt by the Issuers or the Guarantor of any
         such request, a list of similar form and content as of a date not more
         than 15 days prior to the time such list is furnished;

provided, however, that so long as the Trustee is the Security Registrar, no
such list need be furnished.

SECTION 702.      Preservation of Information; Communications to Holders.

         (a) The Trustee shall preserve, in as current a form as is reasonably
practicable, the names and addresses of Holders contained in the most recent
list furnished to the Trustee as provided in Section 701

                                      -41-

<PAGE>

and the names and addresses of Holders received by the Trustee in its capacity
as Security Registrar. The Trustee may destroy any list furnished to it as
provided in Section 701 upon receipt of a new list so furnished.

         (b) If three or more Holders (herein referred to as "applicants") apply
in writing to the Trustee, and furnish to the Trustee reasonable proof that each
such applicant has owned a Security for a period of at least six months
preceding the date of such application, and such application states that the
applicants' desire to communicate with other Holders with respect to their
rights under this Indenture or under the Securities and is accompanied by a copy
of the form of proxy or other communication which such applicants propose to
transmit, then the Trustee shall, within five Business Days after the receipt of
such application, at its election, either

               (1) afford such applicants access to the information preserved at
         the time by the Trustee in accordance with Section 702(a), or

               (2) inform such applicants as to the approximate number of
         Holders whose names and addresses appear in the information preserved
         at the time by the Trustee in accordance with Section 702(a), and as to
         the approximate cost of mailing to such Holders the form of proxy or
         other communication, if any, specified in such application.

If the Trustee shall elect not to afford such applicants access to such
information, the Trustee shall, upon the written request of such applicants,
mail to each Holder whose name and address appear in the information preserved
at the time by the Trustee in accordance with Section 702(a) a copy of the form
of proxy or other communication which is specified in such request, with
reasonable promptness after a tender to the Trustee of the material to be mailed
and of payment, or provision for the payment, of the reasonable expenses of
mailing, unless within five days after such tender the Trustee shall mail to
such applicants and file with the Commission, together with a copy of the
material to be mailed, a written statement to the effect that, in the opinion of
the Trustee, such mailing would be contrary to the best interest of the Holders
or would be in violation of applicable law. Such written statement shall specify
the basis of such opinion. If the Commission, after opportunity for a hearing
upon the objections specified in the written statement so filed, shall enter an
order refusing to sustain any of such objections or if, after the entry of an
order sustaining one or more of such objections, the Commission shall find,
after notice and opportunity for hearing, that all the objections so sustained
have been met and shall enter an order so declaring, the Trustee shall mail
copies of such material to all such Holders with reasonable promptness after the
entry of such order and the renewal of such tender; otherwise the Trustee shall
be relieved of any obligation or duty to such applicants respecting their
application.

         (c) Every Holder of Securities, by receiving and holding the same,
agrees with the Issuers, the Guarantor and the Trustee that neither the Issuers,
the Guarantor nor the Trustee nor any agent of either of them shall be held
accountable by reason of the disclosure of any such information as to the names
and addresses of the Holders in accordance with Section 702(b), regardless of
the source from which such information was derived, and that the Trustee shall
not be held accountable by reason of mailing any material pursuant to a request
made under Section 702(b).

                                      -42-

         (d) Subject to Sections 702(a), 702(b), 702(c) and 601, if the Issuers,
the Guarantor or any other person (other than the Trustee) shall desire to
communicate with Holders of Securities to solicit or obtain from them any proxy,
consent, authorization, waiver, approval of a plan of reorganization,
arrangement or readjustment or other action ("Holder Action"), the Trustee shall
have no duty to participate in such communication or solicitation or the
processing of responses in any manner except (i) to furnish the rules and
regulations and to perform the functions referred to in Section 104 and (ii) to
receive (A) the instruments evidencing the Holder Action together with (B) the
Officers' Certificate and Opinion of Counsel referred to below. Each of the
Issuers and the Guarantor hereby covenants that any and all communications and
solicitations distributed by it in connection with any Holder Action will comply
in all material respects with applicable law, including without limitation
applicable law concerning adequacy of disclosure. The Trustee shall have no
responsibility for the accuracy or completeness of any materials circulated to
solicit any Holder Action nor for any related communications nor for the
compliance thereof with applicable law. No Holder Action shall become effective
until the Trustee shall have received from the Issuers, the Guarantor or other
person who solicited the Holder Action (1) the instruments evidencing such
Holder Action (2) (x) (in the case of Holder Action solicited by the Issuers or
the representative of the Issuers' estate if the Issuers are the debtors in any
bankruptcy or other insolvency proceeding) an Officers' Certificate and (y) (in
all cases) an Opinion of Counsel, each specifying the Holder Action taken and
stating that such Holder Action has been duly and validly taken in compliance
with this Indenture in all material respects. Such Officers' Certificate, if
any, shall also certify that (after giving effect to such Holder Action) no
Event of Default or event or condition which, with notice or lapse of time or
both, would become an Event of Default has occurred and is continuing or has not
been waived.

         (e) The Depositary may grant proxies and otherwise authorize its
participants which own the Global Securities to give or take any Act which a
Holder is entitled to take under the Indenture; provided, however, that the
Depositary has delivered a list of such participants to the Trustee.

SECTION 703.      Reports by Trustee.

exchange.

this Indenture, the Securities or the Guarantee without the consent of any
Holder, so long as such changes, other than those in clause (2), do not
materially and adversely affect the interests of the Holder:

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

               (2) to make any modifications or amendments that do not, in the
         good faith opinion of the Executive Committee of Mediacom Broadband LLC
         and the Board of Directors of Mediacom Broadband Corporation and the
         Guarantor and of the Trustee, adversely affect the interests of the
         Holders in any material respect;

         any requirement of the SEC in connection with the qualification of the
         Indenture under the Trust Indenture Act, provided that such
         modification or amendment does not, in the good faith opinion of the
         Executive Committee of Mediacom Broadband LLC and the Board of
         Directors of Mediacom Broadband Corporation and the Guarantor and of
         the Trustee, adversely affect the interests of the Holders of the
         Securities in any material respect;

         created prior to the execution of such supplemental indenture which is
         entitled to the benefit of such provision;

               (11) to establish the form or terms of Securities of any series

         or facilitate the administration of the trusts hereunder by more than
         one Trustee, pursuant to the requirements of Section 611(b).

SECTION 902.      Amendments or Supplemental Indentures with Consent of Holders

         With the written consent of the Holders of not less than a majority in
aggregate principal amount of the Securities at the time Outstanding, the
Issuers and the Guarantor, when authorized by a Committee Resolution and a Board
Resolution, as the case may be, and the Trustee, at any time and from time to
time, may amend or supplement this Indenture or the Securities. However, without
the consent of each Holder affected, an amendment to this Indenture, the
Securities or the Guarantee may not:

               (1) change the Stated Maturity of the principal of or any
         installment of interest with respect to the Securities;

               (2) reduce the principal amount of, or the rate of interest on,
         the Securities;

         the Securities;

               (4) impair the right to institute suit for the enforcement of any
         payment on or with respect to the Securities;

               (5) reduce the above-stated percentage of Holders of the
         Securities of any series necessary to modify or amend this Indenture;

               (6) modify the foregoing requirements or reduce the percentage of
         Outstanding Securities necessary to waive any covenant or past default;

               (7) if the Securities are convertible, adversely affect the right
         to convert the Securities into Common Stock in accordance with the
         provisions of this Indenture;

               (8) modify or change any provision of this Indenture or the

         Guarantee or this Indenture otherwise than in accordance with the terms
         of this Indenture.

         It shall not be necessary for any Act of the Holders under this Section
902 to approve the particular form of any proposed amendment or supplemental
indenture, but it shall be sufficient if such Act approves the substance
thereof.

         After an amendment or supplemental indenture under this Section 902
becomes effective, the Issuers and the Guarantor shall mail to each Holder a
notice briefly describing the amendment or supplemental indenture.

                                      -47-

<PAGE>

         An amendment or supplemental indenture which changes or eliminates any
covenant or other provision of this Indenture which has expressly been included
solely for the benefit of one or more particular series of Securities, or which
modifies the rights of the Holders of Securities of such series with respect to
such covenant or other provision, shall be deemed not to affect the rights under
this Indenture of the Holders of Securities of any other series.

SECTION 903.      Execution of Supplemental Indentures.

         The Trustee shall sign any supplemental indenture authorized pursuant
to this Article if the amendment contained therein does not adversely affect the
rights, duties, liabilities or immunities of the Trustee. If it does, the
Trustee may, but need not, sign such supplemental indenture. In executing, or
accepting the additional trusts created by, any supplemental indenture permitted
by this Article or the modifications thereby of the trusts created by this
Indenture, the Trustee shall be entitled to receive, and (subject to Section
601) shall be fully protected in relying upon, an Officers' Certificate and an
Opinion of Counsel from each of the Issuers and the Guarantor stating that the
execution of such supplemental indenture is authorized or permitted by this
Indenture.

SECTION 904.      Effect of Supplemental Indentures.

         Upon the execution of any supplemental indenture under this Article,
this Indenture shall be modified in accordance therewith, and such supplemental
indenture shall form a part of this Indenture for all purposes; and every Holder
of Securities theretofore or thereafter authenticated and delivered hereunder
shall be bound thereby.

SECTION 905.      Conformity with Trust Indenture Act.

         Every supplemental indenture executed pursuant to this Article shall
conform to the requirements of the Trust Indenture Act as then in effect.

SECTION 906.      Reference in Securities to Supplemental Indentures.

         Securities of any series authenticated and delivered after the
execution of any supplemental indenture pursuant to this Article may, and shall
if required by the Trustee, bear a notation in form approved by the Trustee as
to any matter provided for in such supplemental indenture. If the Issuers shall
so determine, new Securities of any series so modified as to conform, in the
opinion of the Trustee, the Issuers and the Guarantor, to any such supplemental
indenture may be prepared and executed by the Issuers and the Guarantor and
authenticated and delivered by the Trustee in exchange for Outstanding
Securities of such series.

                                    COVENANTS

SECTION 1001.     Payment of Principal, Premium, if Any, and Interest.

         The Issuers covenant and agree for the benefit of each series of
Securities that they will duly and punctually pay the principal of (and premium,
if any) and interest on the Securities of that series in accordance with the
terms of the Securities and this Indenture. At the option of the Issuers,
payment of principal (and premium, if any) and interest may be made by wire
transfer or (subject to collection) by check mailed to the address of the Person
entitled thereto at such address as shall appear in the Security Register. The
Guarantor covenants that it will, as and when any amounts are due hereunder or
under any Security, duly and punctually pay such amounts as provided in the
Guarantee.

SECTION 1002.     Maintenance of Office or Agency.

         The Issuers and the Guarantor will maintain in each Place of Payment
for any series of Securities an office or agency where Securities of that series
may be presented or surrendered for registration of transfer or exchange and
where notices and demands to or upon the Issuers or the Guarantor in respect of
the Securities of that series and this Indenture may be served. The Issuers and
the Guarantor hereby initially appoint the Trustee their office or agency for
each of said purposes. The Issuers and the Guarantor will give prompt written
notice to the Trustee of the location, and any change in the location, of such
office or agency. If at any time the Issuers or the Guarantor 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, and each of
the Issuers and the Guarantor hereby appoint the Trustee as its agent to receive
all such presentations, surrenders, notices and demands.

         The Issuers and the Guarantor may also from time to time designate one
or more other offices or agencies where the Securities of one or more series 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 or the Guarantor of their
obligation to maintain an office or agency in each Place of Payment for
Securities of any series for such purposes. The Issuers and the Guarantor will
give prompt written notice to the Trustee of any such designation or rescission
and of any change in the location of any such other office or agency.

SECTION 1003.     Money for Securities; Payments to Be Held in Trust.

         If the Issuers shall at any time act as their own Paying Agent with
respect to any series of Securities, they will, on or before each due date of
the principal of (and premium, if any) or interest on any of the Securities of
that series, segregate and hold in trust for the benefit of the Persons entitled
thereto a sum sufficient to pay the principal (and premium, if any) or interest
so becoming due until such sums shall be paid to such Persons or otherwise
disposed of as herein provided and will promptly notify the Trustee of their
action or failure so to act.

                                      -49-

<PAGE>

         Whenever the Issuers or the Guarantor shall have one or more Paying
Agents for any series of Securities, they will, on or prior to each due date of
the principal of (and premium, if any) or interest on any Securities of that
series, deposit with a Paying Agent a sum sufficient to pay the principal (and
premium, if any) or interest so becoming due, such sum to be held in trust for
the benefit of the Persons entitled to such principal, premium or interest, and
(unless such Paying Agent is the Trustee) the Issuers will promptly notify the
Trustee of their action or failure so to act.

         The Issuers or the Guarantor will cause each Paying Agent for any
series of Securities other than the Trustee to execute and deliver to the
Trustee an instrument in which such Paying Agent shall agree with the Trustee,
subject to the provisions of this Section, that such Paying Agent will:

               (1) hold all sums held by it for the payment on the principal of
         (and premium, if any) or interest on Securities of that series in trust
         for the benefit of the Persons entitled thereto until such sums shall
         be paid to such Persons or otherwise disposed of as herein provided;

               (2) give the Trustee notice of any default by the Issuers (or any
         other obligor upon the Securities of that series including, without
         limitation, the Guarantor) in the making of any payment of principal
         (and premium, if any) or interest on the Securities of that series; and

               (3) at any time during the continuance of any such default, upon
         the written request of the Trustee, forthwith pay to the Trustee all
         sums so held in trust by such Paying Agent.

         The Issuers and the Guarantor may at any time, for the purpose of
obtaining the satisfaction and discharge of this Indenture or for any other
purpose, pay, or by Issuers Order and Guarantor Order direct any Paying Agent to
pay, to the Trustee all sums held in trust by the Issuers or such Paying Agent,
such sums to be held by the Trustee upon the same trusts as those upon which
such sums were held by the Issuers, the Guarantor or such Paying Agent; and,
upon such payment by any Paying Agent to the Trustee, such Paying Agent shall be
released from all further liability with respect to such money.

         Any money deposited with the Trustee or any Paying Agent, or then held
by the Issuers or the Guarantor, in trust for the payment of the principal of
(and premium, if any) or interest on any Security of any series 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 Issuers Request, or
(if then held by the Issuers or the Guarantor) shall be discharged from such
trust; and the Holder of such Security shall thereafter, as an unsecured general
creditor, look, only to the Issuers or the Guarantor 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 or the Guarantor 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 or the Guarantor cause to be mailed or published once, in a newspaper
published in the English language, customarily published on each Business Day
and of general circulation in the City, County and State of New York, or both,
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 mailing or
publication, any unclaimed balance of such money then remaining will be repaid
to the Issuers or the Guarantor.

                                      -50-

<PAGE>

         The Issuers shall have no obligation to make payment of principal of
(or premium, if any) or interest on any Security in immediately available funds,
except that if the Issuers shall have received original payment for Securities
in immediately available funds it shall make available immediately available
funds for payment of the principal of such Securities.

SECTION 1004.     Corporate Existence.

         Subject to Article Eight, the Issuers and the Guarantor will do or
cause to be done all things necessary to preserve and keep in full force and
effect their limited liability company or corporate existence, as the case may
be, the limited liability company or corporate rights, as the case may be
(charter and statutory), and franchises; provided, however, that the Issuers and
the Guarantor shall not be required to preserve any such right or franchise if
the Executive Committee or Board of Directors, as the case may be, shall
determine that the preservation thereof is no longer desirable in the conduct of
the business of the Issuers or the Guarantor and that the loss thereof is not
disadvantageous in any material respect to the Holders.

SECTION 1005.     Payment of Taxes and Other Claims.

         The Issuers will pay or discharge, or cause to be paid or discharged,
before the same shall become delinquent, (1) all material taxes, assessments and
governmental charges levied or imposed upon the Issuers or any Subsidiary or
upon the income, profits or property of the Issuers or any Subsidiary material
to the Issuers and their Subsidiaries taken as a whole, and (2) all lawful
claims for labor, materials and supplies which, if unpaid, might by law become a
material lien upon the property of the Issuers or any Subsidiary material to the
Issuers and their Subsidiaries taken as a whole; provided, however, that the
Issuers shall not be required to pay or discharge or cause to be paid or
discharged any such tax, assessment, charge or claim whose amount, applicability
or validity is being contested in good faith by appropriate proceedings and for
which adequate provision has been made.

SECTION 1006.     Compliance with Laws.

         The Issuers shall comply, and shall cause each of their Subsidiaries
material to the Issuers and their Subsidiaries taken as a whole to comply, with
all applicable statutes, rules, regulations, orders and restrictions of the
United States of America, all states and municipalities thereof, and of any
governmental regulatory authority, in respect of the conduct of their respective
businesses and the ownership of their respective properties, except for such
noncompliances as would not in the aggregate have a material adverse effect on
the financial condition or results of operations of the Issuers and their
Subsidiaries, taken as a whole.

SECTION 1007.     Statement by Officers as to Default.

         The Issuers will each deliver to the Trustee, within 120 days after the
end of each fiscal year of the Issuers ending after the date hereof, a
certificate of the principal executive officer, principal financial officer or
principal accounting officer of the managing member, on behalf of Mediacom
Broadband LLC, and of Mediacom Broadband Corporation stating whether or not to
the best knowledge of the signers thereof Mediacom Broadband LLC or Mediacom
Broadband Corporation, as the case may be, is in de-

                                      -51-

<PAGE>

fault in the performance and observance of any of the terms, provisions and
conditions of this Indenture, and if Mediacom Broadband LLC or Mediacom
Broadband Corporation, as the case may be, shall be in default, specifying all
such defaults and the nature and status thereof of which they may have
knowledge.

         The Guarantor will deliver to the Trustee, within 120 days after the
end of each fiscal year ending after the date hereof, a certificate of its
principal executive officer, principal financial officer or principal accounting
officer stating whether or not to the best knowledge of the signers thereof the
Guarantor is in default in the performance and observance of any of the terms,
provisions and conditions of this Indenture, and the Guarantor shall be in
default, specifying all such defaults and the nature and status thereof of which
they may have knowledge.

SECTION 1008.     Waiver of Certain Covenants.

         The Issuers or the Guarantor, as the case may be, may omit in any
particular instance to comply with any term, provision or condition set forth in
Section 1007 if before or after the time for such compliance the Holders of at
least a majority in principal amount of the Outstanding Securities (taken
together as one class) shall, by Act of such Holders, either waive such
compliance in such instance or generally waive compliance with such term,
provision or condition except to the extent so expressly waived, and, until such
waiver shall become effective, the obligations of the Issuers and the Guarantor
and the duties of the Trustee in respect of any such term, provision or
condition shall remain in full force and effect.

SECTION 1009.     Ownership of the Issuers.

         The Guarantor shall at all times own, directly or indirectly, 100% of
the Capital Stock of the Issuers.

                                 ARTICLE ELEVEN
                            REDEMPTION OF SECURITIES

SECTION 1101.     Applicability of Article.

         Securities of any series which are redeemable before their Stated
Maturity shall be redeemable in accordance with their terms and (except as
otherwise specified as contemplated by Section 301 for Securities of any series)
in accordance with this Article.

SECTION 1102.     Election to Redeem; Notice to Trustee.

         The election of the Issuers to redeem any Securities shall be evidenced
by Committee Resolution and a Board Resolution. In case of any redemption at the
election of the Issuers of less than all the Securities of any series, the
Issuers and the Guarantor shall, at least 45 days prior to the Redemption Date
fixed by the Issuers (unless a shorter notice shall be satisfactory to the
Trustee), notify the Trustee of such Redemption Date and of the principal amount
of Securities of such series to be redeemed, such notice to be accompanied by a
written statement signed by an authorized officer of the Issuers the Guarantor
stating that no defaults in the payment of interest or Events of Default with
respect to the Securities of

                                      -52-

<PAGE>

that series have occurred (which have not been waived or cured). In the case of
any redemption of Securities prior to the expiration of any restriction on such
redemption provided in the terms of such Securities or elsewhere in this
Indenture, the Issuers and the Guarantor shall furnish the Trustee an Officers'
Certificate evidencing compliance with such restriction.

SECTION 1103.     Selection by Trustee of Securities to Be Redeemed.

         If less than all the Securities of any series are to be redeemed, the
particular Securities to be redeemed shall be selected not more than 60 days
prior to the Redemption Date by the Trustee, from the Outstanding Securities of
such series not previously called for redemption, by such method as the Trustee
in its sole discretion shall deem fair and appropriate and which may provide for
the selection or redemption of portions (equal to the minimum authorized
denomination for Securities of that series or any integral multiple thereof) of
the principal amount of Securities of such series of a denomination larger than
the minimum authorized denomination for Securities of that series.

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

         For all purposes of this Indenture, unless the context otherwise
requires, all provisions relating to the redemption of Securities shall relate,
in the case of any Securities redeemed or to be redeemed only in part, to the
portion of the principal amount of such Securities which has been or is to be
redeemed.

SECTION 1104.     Notice of Redemption.

         Notice of redemption shall be given by first-class mail, postage
prepaid, mailed not less than 45 nor more than 60 days prior to the Redemption
Date, to each Holder of Securities to be redeemed, at his address appearing in
the Security Register. Any notice which is mailed in the manner herein provided
shall be conclusively presumed to have been duly given, whether or not such
Holder receives the notice. Failure to give notice by mail, or any defect in the
notice to any such Holder in respect of any Security, shall not affect the
validity of the proceedings for the redemption of any other Security.

         All notices of redemption shall state:

               (1) the Redemption Date,

               (2) the Redemption Price and any accrued interest,

               (3) if less than all the Outstanding Securities of any series are
         to be redeemed, the identification (and, in the case of partial
         redemption, the principal amounts) of the particular Securities to be
         redeemed,

               (4) that on the Redemption Date the Redemption Price and any
         accrued interest will become due and payable upon each such Security to
         be redeemed together with accrued interest thereon and, if applicable,
         that interest thereon will cease to accrue on and after said date,

                                      -53-

<PAGE>

               (5) the place or places where such Securities are to be
         surrendered for payment of the Redemption Price and any accrued
         interest,

               (6) that the redemption is for a sinking fund, if such is the
         case, and

               (7) the CUSIP number of the Securities being redeemed.

         Notice of redemption of Securities to be redeemed at the election of
the Issuers shall be given by the Issuers or, at the Issuers' request, by the
Trustee in the name and at the expense of the Issuers.

SECTION 1105.     Deposit of Redemption Price.

         On or prior to any Redemption Date, the Issuers or the Guarantor shall
deposit with the Trustee or with a Paying Agent (or, if the Issuers or the
Guarantor are acting as their own Paying Agent, segregate and hold in trust as
provided in Section 1003) an amount of money, in funds immediately available on
the due date, sufficient to pay the Redemption Price of, and (except if the
Redemption Date shall be an Interest Payment Date) accrued interest on, all the
Securities which are to be redeemed on that date.

SECTION 1106.     Securities Payable on Redemption Date.

         Notice of redemption having been given as aforesaid, the Securities so
to be redeemed shall, on the Redemption Date, become due and payable at the
Redemption Price therein specified together with accrued interest thereon, and
from and after such date (unless the Issuers or the Guarantor shall default in
the payment of the Redemption Price and accrued interest) such Securities shall
cease to bear interest. Upon surrender of any such Security for redemption in
accordance with said notice, such Security shall be paid by the Issuers at the
Redemption Price, together with accrued interest to the Redemption Date;
provided, however, that installments of interest whose Stated Maturity is on the
Redemption Date shall be payable to the Holders of such Securities, or one or
more Predecessor Securities, registered as such at the close of business on the
relevant Record Dates according to their terms and the provisions of Section
307.

         If any Security called for redemption shall not be so paid upon
surrender thereof for redemption, the principal (and premium, if any) shall,
until paid, bear interest from the Redemption Date at the rate prescribed
therefor in the Security.

         The Trustee shall not redeem any Securities of any series pursuant to
this Article (unless all Outstanding Securities of such series are to be
redeemed) or mail or give any notice of redemption of Securities during the
continuance of an Event of Default hereunder known to the Trustee with respect
to such series, except that, where the mailing of notice of redemption of any
Securities shall theretofore have been made, the Trustee shall redeem or cause
to be redeemed such Securities, provided that it shall have received from the
Issuers or the Guarantor a sum sufficient for such redemption. Except as
aforesaid, any moneys theretofore or thereafter received by the Trustee shall,
during the continuance of such Event of Default, be deemed to have been
collected under Article Five and held for the payment of all such Securities of
such series. In case such Event of Default shall have been waived as provided in
Section 513 or

                                      -54-

<PAGE>

the default cured on or before the sixtieth day preceding the Redemption Date,
such moneys shall thereafter be applied in accordance with the provisions of
this Article.

SECTION 1107.     Securities Redeemed in Part.

         Any Security which is to be redeemed only in part shall be surrendered
at a Place of Payment therefor (with, if the Issuers, the Guarantor or the
Trustee so requires, due endorsement by, or a written instrument of transfer in
form satisfactory to the Issuers, the Guarantor and the Trustee duly executed
by, the Holder thereof or his attorney duly authorized in writing), and the
Issuers shall execute, the Guarantor shall execute guarantees on and the Trustee
shall authenticate and deliver to the Holder of such Security without service
charge, a new Security or Securities of the same series, of any authorized
denomination as requested by such Holder, in aggregate principal amount equal to
and in exchange for the unredeemed portion of the principal of the Security so
surrendered.

                                 ARTICLE TWELVE
                                  SINKING FUNDS

SECTION 1201.     Applicability of Article.

         The provisions of this Article shall be applicable to any sinking fund
for the retirement of Securities of a series except as otherwise specified as
contemplated by Section 301 for Securities of such series.

         The minimum amount of any sinking fund payment provided for by the
terms of Securities of any series is herein referred to as a "mandatory sinking
fund payment," and any payment in excess of such minimum amount provided for by
the terms of Securities of any series is herein referred to as an "optional
sinking fund payment." If provided for by the terms of Securities of any series,
the cash amount of any sinking fund payment may be subject to reduction as
provided in Section 1202. Each sinking fund payment shall be applied to the
redemption of Securities of any series as provided for by the terms of
Securities of such series.

SECTION 1202.     Satisfaction of Sinking Fund Payments with Securities.

         The Issuers (1) may deliver Outstanding Securities of a series (other
than any previously called for redemption) and (2) may apply as credit
Securities of a series which have been redeemed either at the election of the
Issuers pursuant to the terms of such Securities or through the application of
permitted optional sinking fund payments pursuant to the terms of such
Securities, in each case in satisfaction of all or any part of any sinking fund
payment with respect to the Securities of such series required to be made
pursuant to the terms of such Securities as provided for by the terms of such
series; provided that such Securities have not been previously so credited. Such
Securities shall be received and credited for such purpose by the Trustee at the
Redemption Price specified in such Securities for redemption through operation
of the sinking fund and the amount of such sinking fund payment shall be reduced
accordingly.

                                      -55-

SECTION 1203.     Redemption of Securities for Sinking Fund.

         Not less than 60 days prior to each sinking fund payment date for any
series of Securities, the Issuers (1) will deliver to the Trustee an Officers'
Certificate (A) stating that no defaults in the payment of interest or Events of
Default with respect to Securities of that series have occurred (which have not
been waived or cured), (B) specifying the amount of the next ensuing sinking
fund payment for that series pursuant to the terms of Securities of that series,
(C) stating whether or not the Issuers intend to exercise their right, if any,
to make an optional sinking fund payment with respect to such series on the next
ensuing sinking fund payment date and, if so, specifying the amount of such
optional sinking fund payment and (D) specifying the portion of such sinking
fund payment, if any, which is to be satisfied by payment of cash and the
portion thereof, if any, which is to be satisfied by delivering and crediting
Securities of that series pursuant to Section 1202 and (2) will also deliver to
the Trustee any Securities to be so delivered. Not less than 30 days before each
such sinking fund payment date the Trustee shall select the Securities of such
series to be redeemed upon such sinking fund payment date in the manner
specified in Section 1103 and cause notice of the redemption thereof to be given
in the name of and at the expense of the Issuers in the manner provided in
Section 1104. Such notice having been duly given, the redemption of such
Securities shall be made upon the terms and in the manner stated in Sections
1105, 1106 and 1107. Failure of the Issuers, on or before any such 60th day, to
deliver such Officers' Certificate and Securities specified in this Section, if
any, shall not constitute a default but shall constitute, on and as of such
date, the irrevocable election of the Issuers (a) that the mandatory sinking
fund payment for such series due on the next succeeding sinking fund payment
date shall be paid entirely in cash without the option to deliver or credit
Securities of such series in respect thereof and (b) that the Issuers will make
no optional sinking fund payment with respect to Securities of such series as
provided in this Article.

         The Trustee shall not redeem or cause to be redeemed any Security of a
series with sinking fund moneys or mail any notice of redemption of Securities
of such series by operation of the sinking fund during the continuance of a
default in payment of interest on such Securities or of any Event of Default
with respect to such series except that, where the mailing of notice of
redemption of any Securities shall therefore have been made, the Trustee shall
redeem or cause to be redeemed such Securities, provided that it shall have
received from the Issuers a sum sufficient for such redemption. Except as
aforesaid, any moneys in the sinking fund for such series at the time when any
such default or Event of Default shall occur, and any moneys thereafter paid
into the sinking fund, shall, during the continuance of such default or Event of
Default, be deemed to have been collected under Article Five and held for the
payment of all such Securities of such series. In case such Event of Default
shall have been waived as provided in Section 513 or the default cured on or
before the 60th day preceding the sinking fund payment date, such moneys shall
thereafter be applied on the next succeeding sinking fund payment date in
accordance with this Section to the redemption of such Securities.

                                ARTICLE THIRTEEN
                             GUARANTEE OF SECURITIES

SECTION 1301.     Unconditional Guarantee.

         Subject to the provisions of this Article Thirteen, the Guarantor
hereby unconditionally guarantees, on an unsecured, unsubordinated basis, to
each Holder of a Security authenticated and delivered by

                                      -56-

<PAGE>

the Trustee and to the Trustee and its successors, irrespective of the validity
and enforceability of this Indenture, the Securities or the obligations of the
Issuers to the Holders or the Trustee hereunder or thereunder, that: (a) the
principal of (and premium, if any) and interest on the Securities will be duly
and punctually paid in full when due, whether at maturity, by acceleration, call
for redemption or otherwise and all obligations of the Issuers or the Guarantor
to the Holders or the Trustee hereunder or thereunder (including amounts due the
Trustee under Section 607 hereof) or under the Securities (including fees,
expenses or other disbursements) will be promptly paid in full or performed, all
in accordance with the terms hereof and thereof; and (b) in case of any
extension of time of payment or renewal of any Securities or any of such other
obligations, the same will be promptly paid in full when due or performed in
accordance with the terms of the extension or renewal, whether at maturity, by
acceleration, call for redemption, purchase or otherwise (all such obligations
guaranteed by the Guarantor, the "Guaranteed Obligations"). Failing payment when
due of any amount so guaranteed, or failing performance of any other obligation
of the Issuers to the Holders, for whatever reason, the Guarantor will be
obligated to pay, or to perform or cause the performance of the same
immediately. An Event of Default under this Indenture or the Securities shall
constitute an event of default under this Guarantee, and shall entitle the
Holders of Securities or the Trustee to accelerate the obligations of the
Guarantor hereunder in the same manner and to the same extent as the obligations
of the Issuers.

         The Guarantor agrees to pay any and all fees and expenses (including
reasonable attorney's fees and expenses) incurred by the Trustee or the Holders
in enforcing any rights under this Article Thirteen with respect to the
Guarantor. Without limiting the generality of the foregoing, this Guarantee
guarantees, to the extent provided herein, the payment of all amounts that
constitute part of the Guaranteed Obligations and would be owed by the Issuers
under this Indenture or the Securities but for the fact that they are
unenforceable or not allowable due to the existence of a bankruptcy,
reorganization or similar proceeding involving the Issuers.

         No stockholder, officer, director, employee or incorporator, past,
present or future, of the Guarantor, as such, shall have any personal liability
under this Guarantee by reason of his, her or its status as such stockholder,
officer, director, employee or incorporator.

SECTION 1302.     Execution and Delivery of Guarantee.

         The Guarantee to be endorsed on the Securities pursuant to Section 204
shall be deemed to include the terms of the Guarantee set forth in this Article
Thirteen. The Guarantor hereby agrees to execute the Guarantee in the form
established pursuant to Section 204 to be endorsed on each Security
authenticated and delivered by the Trustee.

         The Guarantee shall be executed on behalf of the Guarantor by two
Officers of the Guarantor. The signature of such Officer on the Guarantee may be
manual or facsimile.

         A Guarantee bearing the manual or facsimile signature of an individual
who was at any time the proper officer of the Guarantor shall bind the
Guarantor, notwithstanding that such individual has ceased to hold such office
prior to the authentication and delivery of the Security on which the Guarantee
is endorsed or did not hold such office at the date of the Guarantee.

                                      -57-

<PAGE>

         The delivery of any Security by the Trustee after the authentication
thereof hereunder, shall constitute due delivery of the Guarantee endorsed
thereon on behalf of the respective Guarantor. The Guarantor hereby agrees that
the Guarantee set forth in this Article Thirteen and in Section 204 shall remain
in full force and effect notwithstanding any failure to endorse a Guarantee on
any Security.

SECTION 1303.     Obligations of the Guarantor Unconditional.

         Nothing contained in this Article Thirteen or elsewhere in this
Indenture or in any Security is intended to or shall impair, as between the
Guarantor and the Holders and the Trustee, the obligation of the Guarantor,
which is absolute and unconditional, to pay to the Holders and the Trustee the
principal of (and premium, if any), and interest on the Securities (and to the
Trustee amounts due under Section 607) as and when the same shall become due and
payable in accordance with the provisions of this Guarantee, nor shall anything
herein or therein prevent the Trustee or any Holder from exercising all remedies
otherwise permitted by applicable law upon default under this Indenture. Without
limiting the generality of the foregoing, it is agreed that the occurrence of
any one or more of the following shall not affect the liability of the Guarantor
hereunder:

         (a) the lack of validity, regularity or enforceability of this
Indenture or the Securities with respect to the Issuers or any agreement or
instrument relating thereto;

         (b) any change in the time, manner or place of payment of, or in any
other term of any of the Securities, or any other amendment or waiver of or any
consent to departure from this Indenture;

         (c) any amendment or modification of or deletion from or addition or
supplement to or other change in the Guarantee, the Indenture or the Securities
or any other instrument or agreement applicable to any of the parties to the
Guarantee, the Indenture or the Securities;

         (d) any furnishing or acceptance of any security or any guarantee or
other liability of any Subsidiary or any other party, or any release of any
security or any guarantee or other liability of any Subsidiary or any other
party, for the Guaranteed Obligations, or the failure of any security or any
guarantee or other liability of any Subsidiary or any other party or the failure
of any Person to perfect any interest in any collateral;

         (e) any failure, omission or delay on the part of the Issuers to
conform or comply with any term of the Indenture or the Securities or any other
instrument or agreement referred to in paragraph (a) above, including, without
limitation, failure to give notice to the Guarantor or the Trustee of the
occurrence of an Event of Default;

         (f) any waiver of the payment, performance or observance of any of the
obligations, conditions, covenants or agreements contained in the Guarantee, the
Indenture or the Securities, or any other waiver, consent, extension indulgence,
compromise settlement release or other action or inaction under or in respect of
the Guarantee, the Indenture or the Securities or any other instrument or
agreement referred to in paragraph (a) above or any obligation or liability of
the Issuers or any exercise or non-exercise of any right, remedy, power or
privilege under or in respect of any such instrument or agreement or any such
obligation or liability;

                                      -58-

<PAGE>

         (g) any failure, omission or delay on the part of the Trustee or any
Holder of Securities to enforce, assert, exercise or continue exercising any
right, power or remedy conferred on it in the Guarantee or the Indenture, or any
such failure, omission or delay on the part of the Trustee or any Holder of
Securities in connection with the Guarantee, the Indenture or the Securities, or
any other action on the part of the Trustee or any Holder of Securities;

         (h) the assignment of any right, title or interest of the Trustee or
any Holder in this Indenture or the Securities to any other Person; any
voluntary or involuntary bankruptcy, insolvency, suspension of payments,
reorganizations, arrangement, readjustment, assignment for the benefit of
creditors, receivership, liquidation or similar proceedings with respect to the
Issuers, the Guarantor or any other Person or any of their respective properties

         (i) or creditors, or any action taken by any trustee, receiver or
similar officer or by any court in any such proceeding;

         (j) any limitation on the liability or obligations of the Issuers or
any other Person under the Guarantee, the Indenture or the Securities, or any
partial discharge, cancellation or unenforceability of the Guarantee, the
Indenture or the Securities or any other agreement or instrument referred to in
paragraph (c) above or any term hereof, to the extent not mutually agreed upon
by the parties hereto;

         (k) any merger or consolidation of the Issuers or the Guarantor into or
with any other corporation or any sale, lease or transfer of any of the assets
of the Issuers or the Guarantor to any other Person;

         (l) any change in the ownership of any shares of Capital Stock of the
Guarantor, or any change in the corporate relationship between the Issuers and
the Guarantor, or any termination of such relationship, or any change in the
corporate existence, structure, or ownership of the Issuers;

         (m) any release or discharge, by operation of law, of the Guarantor
from the performance or observance of any obligation, covenant or agreement
contained in the Guarantee, the Indenture or the Securities;

         (n) any action, failure, omission or delay on the part of the Trustee
or any Holder of Securities that may impede any Guarantor from acquiring or
subrogating such Holders or Trustee's rights or benefits; or

         (o) any other occurrence, circumstance, happening or event whatsoever,
whether similar or dissimilar to the foregoing, whether foreseen or unforeseen,
and any other circumstance that might otherwise constitute a legal defense or
discharge of the liabilities of the Guarantor or that might otherwise limit
recourse against the Guarantor; it being the intent of the Guarantor that its
obligations hereunder shall not be discharged except by payment of all amounts
owing pursuant to this Indenture or the Securities.

         The Guarantee shall continue to be effective or be reinstated, as the
case may be, if at any time any payment or performance with respect to any of
the Securities is rescinded or must otherwise be returned by the Trustee, any
Holder or any other Person upon the insolvency, bankruptcy or reorganization

                                      -59-

<PAGE>

of the Issuers or otherwise, all as though such payment or performance had not
been made or occurred. In the event that any payment or any part thereof is
rescinded or must otherwise be returned, the Securities shall be reinstated and
deemed reduced only by such amount paid and not so rescinded or returned. The
obligations of the Guarantor under the Guarantee shall not be subject to
reduction, termination or other impairment by any set-off, recoupment,
counterclaim or defense or for any other reason.

SECTION 1304.     Waivers.

         The Guarantor hereby irrevocably waives, to the extent permitted by
applicable law:

               (a) promptness, demand for payment, diligence, presentment,
         notice of acceptance and any other notice with respect to any of the
         Guaranteed Obligations and the Guarantee;

         (b) any requirement that the Trustee, any Holder or any other Person
protect, secure, perfect or insure any Lien or any property subject thereto or
exhaust any right, sue or take any action against the Issuers or any other
Person, or obtain any relief pursuant to this Indenture or pursue any other
available remedy prior to making a claim against the Guarantor hereunder;

         (c) all right to trial by jury in any action, proceeding or
counterclaim arising out of or relating to this Indenture or the Securities;

         (d) filing of claims with a court in the event of insolvency or
bankruptcy of the Issuers, any right to require a proceeding first against the
Issuers, protest or notice with respect to such Security or the Indebtedness
evidenced thereby and all demands whatsoever;

         (e) any defense arising by reason of any claim or defense based upon an
election of remedies by the Trustee or any Holder that in any manner impairs,
reduces, releases or otherwise adversely affects its subrogation, contribution
or reimbursement rights or other rights to proceed against the Issuers or any
other Person;

         (f) any right to which it may be entitled to have the assets of the
Issuers first be used as payment of the Issuers' or the Guarantor's obligations
hereunder prior to any amounts being claimed from or paid by the Guarantor
hereunder; or

         (g) any duty on the part of the Trustee or any Holder to disclose to
the Guarantor any matter, fact or thing relating to the business, operation or
condition of the Issuers and its assets now known or hereafter known by the
Trustee or such Holder.

SECTION 1305.     Amendment, Etc.

         No amendment, modification or waiver of any provision of this Indenture
relating to the Guarantor or consent to any departure by the Guarantor or any
other Person from any such provision will in any event be effective unless it is
signed by the Guarantor and the Trustee.

         This instrument may be executed in any number of counterparts, each of
which so executed shall be deemed to be an original, but all such counterparts
shall together constitute but one and the same instrument.

                                ARTICLE FOURTEEN
                                  SUBORDINATION

SECTION 1401.     Agreement to Subordinate.

         (a) The Issuers covenant and agree, and each Holder of Securities
issued hereunder by such Holder's acceptance thereof likewise covenants and
agrees, that (except as otherwise specified as contemplated by Section 301 for
Securities of any series) all Securities shall be issued subject to the
provisions of this article; and each Holder of a Security, whether upon original
issue or upon transfer or assignment thereof, accepts and agrees to be bound by
such provisions.

         (b) The payment by the Issuers of the principal of, and interest on,
the Securities issued hereunder shall, to the extent and in the manner
hereinafter set forth, be subordinated and junior in right of payment to the
prior payment in full of all Senior Indebtedness of the Issuers, whether
outstanding at the date of this Indenture or thereafter incurred.

         (c) No provision of this article shall prevent the occurrence of any
default or Event of Default hereunder.

SECTION 1402.     Default on Senior Indebtedness.

         (a) No direct or indirect payment by or on behalf of the Issuers of
principal of, premium, if any, or interest on the Securities, whether pursuant
to the terms of the Securities or upon acceleration, by way of repurchase,
redemption, defeasance or otherwise, will be made if, at the time of such
payment, there exists a default in the payment when due of all or any portion of
the obligations under or in respect of any Senior Indebtedness, whether at
maturity, on account of mandatory redemption or prepayment, acceleration or
otherwise, and such default shall not have been cured or waived or the benefits
of this sentence waived by or on of the holders of Senior Indebtedness.

         (b) In addition, during the continuance of any non-payment default or
non-payment event of default with respect to any Senior Indebtedness pursuant to
which the maturity thereof may be accelerated, and upon receipt by the Trustee
of written notice (a "Payment Blockage Notice") from a holder or holders of such
Senior Indebtedness or the trustee or agent acting on behalf of such Senior
Indebtedness, then, unless and until such default or event of default has been
cured or waived or has ceased to exist or such Senior Indebtedness has been
discharged or repaid in full in cash, or the requisite holders of such Senior
Indebtedness have otherwise agreed in writing, no payment of any kind or
character with respect to any principal of or interest on or distribution will
be made by or on behalf of the Issuers on account of or with respect to the
Securities, during a period (a "Payment Blockage Period") commencing on the date
of receipt of such Payment Blockage Notice by the Trustee and ending 179 days
thereafter.

                                      -61-

<PAGE>

         Notwithstanding anything herein to the contrary, (x) in no event will a
Payment Blockage Period extend beyond 179 days from the date the Payment
Blockage Notice in respect thereof was given and (y) there must be 180 days in
any 360-day period during which no Payment Blockage Period is in effect. Not
more than one Payment Blockage Period may be commenced with respect to the
Securities during any period of 360 consecutive days. No default or event of
default that existed or was continuing on the date of commencement of any
Payment Blockage Period with respect to the Senior Indebtedness initiating such
Payment Blockage Period may be, or be made, the basis for the commencement of
any other Payment Blockage Period by the holder or holders of such Senior
Indebtedness or the trustee or agent acting on behalf of such Senior
Indebtedness, whether or not within a period of 360 consecutive days, unless
such default or event of default has been cured or waived for a period of not
less than 90 consecutive days.

         (c) In the event that, notwithstanding the foregoing, any payment shall
be received by the Trustee when such payment is prohibited by the preceding
paragraph of this section, such payment shall be held in trust for the benefit
of, and shall be paid over or delivered to, the holders of Senior Indebtedness
or their respective representatives, or to the trustee or trustees under any
indenture pursuant to which any instruments evidencing such Senior Indebtedness
may have been issued, as their respective interests may appear, as calculated by
the Issuers, to the extent necessary to pay such Senior Indebtedness in full, in
cash, after giving effect to any concurrent payment or distribution to or for
the benefit of the holders of such Senior Indebtedness, before any payment or
distribution is made to the Holders or to the Trustee.

SECTION 1403.     Liquidation; Dissolution; Bankruptcy.

         (a) Upon any distribution of assets of either of the Issuers of any
kind or character, whether in cash, property or securities, to creditors upon
any total or partial dissolution, winding-up, liquidation or reorganization of
such Issuer, whether voluntary or involuntary, assignment for the benefit of
creditors or marshalling of such Issuer's assets, or in bankruptcy, insolvency,
receivership or other similar proceedings, whether voluntary or involuntary, all
principal, premium, if any, and interest due or to become due to all Senior
Indebtedness of such Issuer shall first be paid in full in cash, or such payment
duly provided for to the satisfaction of the holders of the Senior Indebtedness,
before the Holders are entitled to receive or retain any payment; and upon any
such dissolution or winding-up or liquidation or reorganization, any payment by
such Issuer, or distribution of assets of such Issuer of any kind or character
whether in cash, property or securities, which the Holders or the Trustee would
be entitled to receive from such Issuer, except for the provisions of this
article, shall be paid by such Issuer or by any receiver, trustee in bankruptcy,
liquidating trustee, agent or other Person making such payment or distribution,
or by the Holders or by the Trustee under this Indenture if received by them or
it, directly to the holders of Senior Indebtedness of such Issuer or their
respective representatives, or to the trustee or trustees under any indenture
pursuant to which any instruments evidencing such Senior Indebtedness may have
been issued, as their respective interests may appear, as calculated by such
Issuer, to the extent necessary to pay such Senior Indebtedness in full in cash,
or such payment duly provided for to the satisfaction of the holders of the
Senior Indebtedness, after giving effect to any concurrent payment or
distribution to or for the benefit of the holders of such Senior Indebtedness,
before any payment or distribution is made to the Holders or to the Trustee.

                                      -62-

<PAGE>

         (b) In the event that, notwithstanding the foregoing, any payment or
distribution of assets of either of the Issuers of any kind or character,
whether in cash, property or securities, prohibited by the foregoing, shall be
received by the Trustee before all Senior Indebtedness of such Issuer is paid in
full, or provision is made for such payment in money in accordance with its
terms, such payment or distribution shall be held in trust for the benefit of,
and shall be paid over or delivered to, the holders of such Senior Indebtedness
or their respective representatives, or to the trustee or trustees under any
indenture pursuant to which any instruments evidencing such Senior Indebtedness
may have been issued, as their respective interests may appear, as calculated by
such Issuer, to the extent necessary to pay such Senior Indebtedness in full, in
cash, after giving effect to any concurrent payment or distribution to or for
the benefit of the holders of such Senior Indebtedness, before any payment or
distribution is made to the Holders or to the Trustee.

         (c) For purposes of this article, the words "cash, property or
securities" shall not be deemed to include shares of stock of either of the
Issuers as reorganized or readjusted, or securities of either of the Issuers or
any other corporation provided for by a plan of reorganization or readjustment,
the payment of which is subordinated at least to the extent provided in this
article with respect to the Securities to the payment of all Senior Indebtedness
of such Issuer that may at the time be outstanding; provided, however, that (i)
such Senior Indebtedness is assumed by the new corporation, if any, resulting
from any such reorganization or readjustment, and (ii) the rights of the holders
of such Senior Indebtedness are not, without the consent of such holders,
altered by such reorganization or readjustment. The amalgamation or
consolidation of either of the Issuers with, or the merger of either of the
Issuers into, another corporation or the liquidation or dissolution of either of
the Issuers following the conveyance or transfer of its properties or assets
substantially as an entirety, to another corporation upon the terms and
conditions provided for in Article Eight of this Indenture shall not be deemed a
dissolution, winding-up, liquidation or reorganization for the purposes of this
Section 1303 if such other corporation shall, as part of such amalgamation,
consolidation, merger, conveyance or transfer, comply with the conditions stated
in Article Eight of this Indenture. Nothing in Section 1302 or in this section
shall apply to claims of, or payments to, the Trustee under or pursuant to
Section 607 of this Indenture.

         (d) If the Trustee or any Holder of Securities does not file a proper
claim or proof of debt in the form required in any proceeding referred to above
prior to 30 days before the expiration of the time to file such claim in such
proceeding, then the holder of any Senior Indebtedness is hereby authorized, and
has the right, to file an appropriate claim or claims for or on behalf of such
Holder of Securities.

SECTION 1404.     Subrogation.

         (a) Subject to the payment in full of all Senior Indebtedness of either
of the Issuers then outstanding, the rights of the Holders shall be subrogated
to the rights of the holders of such Senior Indebtedness to receive payments or
distributions of cash, property or securities of such Issuer applicable to such
Senior Indebtedness until the principal of and interest on the Securities shall
be paid in full; and, for the purposes of such subrogation, no payments or
distributions to the holders of such Senior Indebtedness of any cash, property
or securities to which the Holders or the Trustee would be entitled except for
the provisions of this article, and no payment over pursuant to the provisions
of this article to or for the benefit of the holders of such Senior Indebtedness
by Holders or the Trustee, shall, as between such Issuer, its creditors other
than holders of Senior Indebtedness of such Issuer, and the Holders, be deemed
to be a

                                      -63-

<PAGE>

payment by such Issuer to or on account of such Senior Indebtedness. It is
understood that the provisions of this article are and are intended solely for
the purposes of defining the relative rights of the Holders, on the one hand,
and the holders of such Senior Indebtedness, on the other hand.

         (b) Nothing contained in this article or elsewhere in this Indenture or
in the Securities is intended to or shall impair, as between the Issuers, their
creditors other than the holders of Senior Indebtedness of the Issuers, and the
Holders, the obligation of the Issuers, which is absolute and unconditional, to
pay to the Holders the principal of and interest on the Securities as and when
the same shall become due and payable in accordance with their terms, or is
intended to or shall affect the relative rights of the Holders and creditors of
the Issuers other than the holders of Senior Indebtedness of the Issuers nor
shall anything herein or therein prevent the Trustee or any Holder of Securities
from exercising all remedies otherwise permitted by applicable law upon default
under this Indenture, subject to the rights, if any, under this article of the
holders of such Senior Indebtedness in respect of cash, property or securities
of the Issuers received upon the exercise of any such remedy.

         (c) Upon any payment or distribution of assets of either of the Issuers
referred to in this article, the Trustee, subject to the provisions of Section
601 of this Indenture, and the Holders shall be entitled to rely conclusively
upon any order or decree made by any court of competent jurisdiction in which
such dissolution, winding-up, liquidation or reorganization proceedings are
pending, or a certificate of the receiver, trustee in bankruptcy, liquidation
trustee, agent or other Person making such payment or distribution, delivered to
the Trustee or the Holders, for the purposes of ascertaining the Persons
entitled to participate in such distribution, the holders of Senior Indebtedness
and other indebtedness of such Issuer the amount thereof or payable thereon, the
amount or amounts paid or distributed thereon and all other facts pertinent
thereto or to this article.

SECTION 1405.     Trustee to Effectuate Subordination

         Each Holder of Securities by such Holder's acceptance thereof
authorizes and directs the Trustee on such Holder's behalf to take such action
as may be necessary or appropriate to effectuate the subordination provided in
this article and appoints the Trustee such Holder's attorney-in-fact for any and
all such purposes.

SECTION 1406.     Notice by the Issuers.

         (a) The Issuers shall give prompt written notice to a Responsible
Officer of the Trustee of any fact known to the Issuers that would prohibit the
making of any payment of monies to or by the Trustee in respect of the
Securities pursuant to the provisions of this article. Notwithstanding the
provisions of this article or any other provision of this Indenture, the Trustee
shall not be charged with knowledge of the existence of any facts that would
prohibit the making of any payment of monies to or by the Trustee in respect of
the Securities pursuant to the provisions of this article, unless and until a
Responsible Officer of the Trustee shall have received written notice thereof
from the Issuers or a Holder or holders of Senior Indebtedness or from any
representative or trustee therefor; and before the receipt of any such written
notice, the Trustee, subject to the provisions of Section 601 of this Indenture,
shall be entitled in all respects to assume that no such facts exist; provided,
however, that if the Trustee shall not have received the notice provided for in
this section at least two Business Days prior to the date upon which by

                                      -64-

<PAGE>

the terms hereof any money may become payable for any purpose (including,
without limitation, the payment of the principal of or interest on any
Security), then, anything herein contained to the contrary notwithstanding, the
Trustee shall have full power and authority to receive such money and to apply
the same to the purposes for which such money was received, and shall not be
affected by any notice to the contrary that may be received by it within two
Business Days prior to such date.

         (b) The Trustee, subject to the provisions of Section 601 of this
Indenture, shall be entitled to conclusively rely on the delivery to it of a
written notice by a Person representing himself to be a holder of Senior
Indebtedness of either of the Issuers (or a trustee or representative on behalf
of such holder), to establish that such notice has been given by a holder of
such Senior Indebtedness or a trustee or representative on behalf of any such
holder or holders. In the event that the Trustee determines in good faith that
further evidence is required with respect to the right of any Person as a holder
of such Senior Indebtedness to participate in any payment or distribution
pursuant to this article, the Trustee may request such Person to furnish
evidence to the reasonable satisfaction of the Trustee as to the amount of such
Senior Indebtedness held by such Person, the extent to which such Person is
entitled to participate in such payment or distribution and any other facts
pertinent to the rights of such Person under this article and, if such evidence
is not furnished, the Trustee may defer any payment to such Person pending
judicial determination as to the right of such Person to receive such payment.

SECTION 1407.     Rights of the Trustee; Holders of Senior Indebtedness.

         (a) The Trustee in its individual capacity shall be entitled to all the
rights set forth in this article in respect of any Senior Indebtedness at any
time held by it, to the same extent as any other holder of Senior Indebtedness,
and nothing in this Indenture shall deprive the Trustee of any of its rights as
such holder.

         (b) With respect to the holders of Senior Indebtedness of the Issuers,
the Trustee undertakes to perform or to observe only such of its covenants and
obligations as are specifically set forth in this article and no implied
covenants or obligations with respect to the holders of such Senior Indebtedness
shall be read into this Indenture against the Trustee. The Trustee shall not be
deemed to owe any fiduciary duty to the holders of such Senior Indebtedness and,
subject to the provisions of Section 601 of this Indenture, the Trustee shall
not be liable to any holder of such Senior Indebtedness if it shall pay over or
deliver to Holders, the Issuers or any other Person money or assets to which any
holder of such Senior Indebtedness shall be entitled by virtue of this article
or otherwise.

SECTION 1408.     Subordination May Not Be Impaired.

         (a) No right of any present or future holder of any Senior Indebtedness
of either of the Issuers to enforce subordination as herein provided shall at
any time in any way be prejudiced or impaired by any act or failure to act on
the part of such Issuer or by any act or failure to act, in good faith, by any
such holder, or by any noncompliance by such Issuer with the terms, provisions
and covenants of this Indenture, regardless of any knowledge thereof that any
such holder may have or otherwise be charged with.

         (b) Without in any way limiting the generality of the foregoing
paragraph, the holders of Senior Indebtedness of either of the Issuers may, at
any time and from time to time, without the consent of or

                                      -65-

<PAGE>

notice to the Trustee or the Holders, without incurring responsibility to the
Holders and without impairing or releasing the subordination provided in this
article or the obligations hereunder of the Holders to the holders of such
Senior Indebtedness, do any one or more of the following: (i) change the manner,
place or terms of payment or extend the time of payment of, or renew or alter,
such Senior Indebtedness, or otherwise amend or supplement in any manner such
Senior Indebtedness or any instrument evidencing the same or any agreement under
which such Senior Indebtedness is outstanding; (ii) sell, exchange, release or
otherwise deal with any property pledged, mortgaged or otherwise securing such
Senior Indebtedness; (iii) release any Person liable in any manner for the
collection of such Senior Indebtedness; and (iv) exercise or refrain from
exercising or waive any rights against such Issuer and any other Person.

         (c) Each present and future holder of Senior Indebtedness shall be
entitled to the benefit of the provisions of this article notwithstanding that
such holder is not a party to this Indenture.

SECTION 1409.     Article Applicable to Paying Agents.

         In case at any time any Paying Agent other than the Trustee shall have
been appointed by the Issuers and be then acting hereunder, the term "Trustee"
as used in this article shall in such case (unless the context otherwise
requires) be construed as extending to and including such Paying Agent within
its meaning as fully for all intents and purposes as if such Paying Agent were
named in this article in addition to or in place of the Trustee; provided,
however, that this section shall not apply to the Issuers or any Affiliate of
the Issuers if it or such Affiliate acts as Paying Agent.

SECTION 1410.     Defeasance of this Article.

         Notwithstanding anything contained herein to the contrary, payments
from cash or the proceeds of United States Government Obligations held in trust
under Article Four hereof by the Trustee (or other qualifying trustee) and which
were deposited in accordance with the terms of Article Four hereof and not in
violation of Section 1302 hereof for the payment of principal of and interest on
the Securities shall not be subordinated to the prior payment of any Senior
Indebtedness or subject to the restrictions set forth in this article, and none
of the Holders shall be obligated to pay over any such amount to the Issuers or
any holder of Senior Indebtedness or any other creditor of the Issuers.

SECTION 1411.     Subordination Language to be Included in Securities

         Each Security shall contain a subordination provision which will be
substantially in the following form:

                  "The Securities are subordinated in right of payment, in the
                  manner and to the extent set forth in the Indenture, to the
                  prior payment in full of all Senior Indebtedness (as defined
                  in the Indenture, or as set forth in one or more indentures
                  supplemental hereto, a Board Resolution in accordance with
                  Section 301 of the Indenture or in this Security). Each Holder
                  by accepting a Security agrees to such subordination and
                  authorizes the Trustee to give it affect."

                                      -66-
