     INDENTURE dated as of February 6, 2001 between Insight Communications
Company, Inc., a Delaware corporation (the "Issuer"), and The Bank of New York,
a New York banking corporation, as trustee (the "Trustee").

     The Issuer and the Trustee agree as follows for the benefit of each other
and for the equal and ratable benefit of the Holders of the 12 1/4% Senior
Discount Notes due 2011 (the "Notes"):

                                  ARTICLE 1.
                         DEFINITIONS AND INCORPORATION
                                 BY REFERENCE

Section 1.01  Definitions.

     "144A Global Note" means a global note substantially in the form of Exhibit
A1 hereto bearing the Global Note Legend and the Private Placement Legend and
deposited with or on behalf of, and registered in the name of, the Depositary or
its nominee, which Global Note will be issued in a denomination equal to the
outstanding principal amount of the Notes sold in reliance on Rule 144A.

     "Accreted Value" means, as of any date of determination, prior to February
15, 2006, with respect to any note, the sum of (a) the initial offering price to
investors of such note and (b) the portion of the excess of the principal amount
of such note over the initial offering price (which shall be calculated by
discounting the aggregate principal amount at maturity of such note of a rate of
12 1/4% per annum, compounded semi-annually on each February 15 and August 15
from February 15, 2006 to the date of issuance) which shall have been accreted
thereon through such date, such amount to be so accreted on a daily basis at a
rate of 12 1/4% per annum of the initial offering price of such note, compounded
semi-annually on each February 15 and August 15 from the date of issuance of the
notes through the date of determination, computed on the basis of a 360-day year
of twelve 30-day months.

     "Acquired Debt" means, with respect to any specified Person, (1)
Indebtedness of any other Person existing at the time such other Person is
merged with or into or became a Subsidiary of such specified Person, whether or
not such Indebtedness is incurred in connection with, or in contemplation of,
such other Person merging with or into, or becoming a Subsidiary of, such
specified Person and (2) Indebtedness secured by a Lien encumbering any asset
acquired by such specified Person.

     "Adjusted Debt to Cash Flow Ratio" means, as of any date of determination
(as used in this definition, the "Determination Date"), the ratio of (a) the
Consolidated Indebtedness of the Issuer less the Consolidated Indebtedness of
Insight Midwest as of such Determination Date, to (b) four times the
Consolidated Cash Flow of the Issuer, less the Consolidated Cash Flow of Insight
Midwest, in each case, for the most recent full fiscal quarter ending
immediately prior to such Determination Date for which internal financial
statements are available (the "Measurement Period"), determined on a pro forma
basis after giving effect to all acquisitions or dispositions of assets made by
the applicable Person and its Restricted Subsidiaries from the beginning of such
quarter through and including such Determination Date (including any related
financing transactions) as if such acquisitions and dispositions had occurred at
the beginning of such quarter. For purposes of calculating Consolidated Cash
Flow for the Measurement Period immediately prior to the relevant Determination
Date, (i) any Person that is a Restricted Subsidiary on the Determination Date
(or would become a Restricted Subsidiary on such Determination Date in
connection with the transaction that requires the determination of such
Consolidated Cash Flow) will be deemed to have been a Restricted Subsidiary at
all times during the Measurement Period; (ii) any Person that is not a
Restricted Subsidiary on such Determination Date (or would cease to be a
Restricted Subsidiary on such Determination Date in connection with the
transaction that requires the determination of such Consolidated Cash Flow) will
be deemed not to have been a Restricted Subsidiary at any time

                                       1
<PAGE>

during such Measurement Period; and (iii) if the applicable Person or any
Restricted Subsidiary shall have in any manner (x) acquired (including through
an Asset Acquisition or the commencement of activities constituting such
operating business) or (y) disposed of (including by way of an Asset Sale or the
termination or discontinuance of activities constituting such operating
business) any operating business during such Measurement Period or after the end
of such period and on or prior to such Determination Date, such calculation will
be made on a pro forma basis in accordance with generally accepted accounting
principles consistently applied, as if, in the case of an Asset Acquisition or
the commencement of activities constituting such operating business, all such
transactions had been consummated on the first day of such Measurement Period,
and, in the case of an Asset Sale or termination or discontinuance of activities
constituting such operating business, all such transactions had been consummated
prior to the first day of such Measurement Period.

     "Adjusted Senior Debt to Cash Flow Ratio" means, as of any date of
determination (as used in this definition, the "Determination Date"), the ratio
of (a) the Consolidated Indebtedness of the Issuer that constitutes senior
Indebtedness incurred under Credit Facilities, less the Consolidated
Indebtedness of Insight Midwest that constitutes senior Indebtedness incurred
under Credit Facilities as of such Determination Date, to (b) four times the
Consolidated Cash Flow of the Issuer less the Consolidated Cash Flow of Insight
Midwest, in each case, for the most recent full fiscal quarter ending
immediately prior to such Determination Date for which internal financial
statements are available (the "Measurement Period"), determined on a pro forma
basis after giving effect to all acquisitions or dispositions of assets made by
the applicable Person and its Restricted Subsidiaries from the beginning of such
quarter through and including such Determination Date (including any related
financing transactions) as if such acquisitions and dispositions had occurred at
the beginning of such quarter. For purposes of calculating Consolidated Cash
Flow for the Measurement Period immediately prior to the relevant Determination
Date, (i) any Person that is a Restricted Subsidiary on the Determination Date
(or would become a Restricted Subsidiary on such Determination Date in
connection with the transaction that requires the determination of such
Consolidated Cash Flow) will be deemed to have been a Restricted Subsidiary at
all times during the Measurement Period; (ii) any Person that is not a
Restricted Subsidiary on such Determination Date (or would cease to be a
Restricted Subsidiary on such Determination Date in connection with the
transaction that requires the determination of such Consolidated Cash Flow) will
be deemed not to have been a Restricted Subsidiary at any time during such
Measurement Period; and (iii) if the applicable Person or any Restricted
Subsidiary shall have in any manner (x) acquired (including through an Asset
Acquisition or the commencement of activities constituting such operating
business) or (y) disposed of (including by way of an Asset Sale or the
termination or discontinuance of activities constituting such operating
business) any operating business during such Measurement Period or after the end
of such period and on or prior to such Determination Date, such calculation will
be made on a pro forma basis in accordance with generally accepted accounting
principles consistently applied, as if, in the case of an Asset Acquisition or
the commencement of activities constituting such operating business, all such
transactions had been consummated on the first day of such Measurement Period,
and, in the case of an Asset Sale or termination or discontinuance of activities
constituting such operating business, all such transactions had been consummated
prior to the first day of such Measurement Period.

     "Affiliate" of any specified Person means any other Person directly or
indirectly controlling or controlled by or under direct or indirect common
control with such specified Person. For purposes of this definition, "control,"
as used with respect to any Person, shall mean the possession, directly or
indirectly, of the power to direct or cause the direction of the management or
policies of such Person, whether through the ownership of voting securities, by
agreement or otherwise; provided, that beneficial ownership of more than 10% of

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

          The Trustee shall, upon a written order of the Issuer signed by an
Officer of the Issuer (an "Authentication Order"), authenticate Notes for
original issue up to the aggregate principal amount stated in paragraph 4 of the
Notes. The aggregate principal amount of Notes outstanding at any time may not
exceed such amount except as provided in Section 2.07 hereof.

          The Trustee may appoint an authenticating agent acceptable to the
Issuer to authenticate Notes. An authenticating agent may authenticate Notes
whenever the Trustee may do so. Each reference in this Indenture to
authentication by the Trustee includes authentication by such agent. An

Affiliate of the Issuer.

Section 2.03   Registrar and Paying Agent.

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

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

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

Section 2.04   Paying Agent to Hold Money in Trust.

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

Section 2.05   Holder Lists.

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

                                       20

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

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

          Upon satisfaction of the conditions of any of the subparagraphs in
     this Section 2.06(d)(ii), the Trustee shall cancel the Definitive Notes and

Unrestricted Global Notes. A Holder of an Unrestricted Definitive Note may

form of a beneficial interest in an Unrestricted Global Note at any time. Upon
receipt of a request for such an exchange or transfer, the Trustee shall cancel
the applicable Unrestricted Definitive Note and increase or cause to be
increased the aggregate principal amount of one of the Unrestricted Global
Notes.

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

     (e)  Transfer and Exchange of Definitive Notes for Definitive Notes. Upon
request by a Holder of Definitive Notes and such Holder's compliance with the
provisions of this Section 2.06(e), the Registrar shall register the transfer or
exchange of Definitive Notes. Prior to such registration of transfer or
exchange, the requesting Holder shall present or surrender to the Registrar the
Definitive Notes duly endorsed or accompanied by a written instruction of
transfer in form satisfactory to the Registrar duly executed by such Holder or
by its attorney, duly authorized in writing. In addition, the requesting Holder
shall provide any additional certifications, documents and information, as
applicable, required pursuant to the following provisions of this Section
2.06(e).

          (i)   Restricted Definitive Notes to Restricted Definitive Notes. Any

delivery thereof in the form of an Unrestricted Definitive Note if:

                (A) such exchange or transfer is effected pursuant to the
Exchange Offer in accordance with the Registration Rights Agreement and the
Holder, in the case of an exchange, or the transferee, in the case of a
transfer, certifies in the applicable Letter of Transmittal that it is not (1) a

                (B) any such transfer is effected pursuant to the Shelf

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

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

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

          longer required in order to maintain compliance with the Securities
          Act.

          (iii) Unrestricted Definitive Notes to Unrestricted Definitive Notes.
A Holder of Unrestricted Definitive Notes may transfer such Notes to a Person

thereof.

Restricted Definitive Notes accepted for exchange in the Exchange Offer.
Concurrently with the issuance of such Notes, the Trustee shall cause the
aggregate principal amount of the applicable Restricted Global Notes to be

authenticate and deliver to the Persons designated by the Holders of Definitive
Notes so accepted Definitive Notes in the appropriate principal amount.

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

     (i)  General Provisions Relating to Transfers and
Exchanges.

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

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

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

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

                                       30
<PAGE>

          (v)    The Issuer shall not be required (A) to issue, to register the
transfer of or to exchange any Notes during a period beginning at the opening of
business 15 days before the day of mailing of a notice of redemption of Notes
for redemption under Section 3.02 hereof and ending at the close of business on
the day of selection, (B) to register the transfer of or to exchange any Note so
selected for redemption in whole or in part, except the unredeemed portion of
any Note being redeemed in part or (C) to register the transfer of or to
exchange a Note between a record date and the next succeeding Interest Payment
Date.

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

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

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

          (ix)   The Trustee shall have no obligation or duty to monitor,
determine or inquire as to compliance with any restrictions on transfer imposed
under this Indenture or under applicable law with respect to any transfer of any
interest in any Note (including any transfers between or among Depositary
Participants or beneficial owners of interests in any Global Note) other than to
require delivery of such certificates and other documentation or evidence as are
expressly required by, and to do so if and when expressly required by the terms
of, this Indenture, and to examine the same to determine substantial compliance
as to form with the express requirements hereof.

Section 2.07   Replacement Notes.

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

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

Section 2.08   Outstanding Notes.

     The Notes outstanding at any time are all the Notes authenticated by the
Trustee except for those canceled by it, those delivered to it for cancellation,
those reductions in the interest in a Global Note effected by the Trustee in
accordance with the provisions hereof, and those described in this Section 2.08
as not outstanding. Except as set forth in Section 2.09 hereof, a Note does not
cease to be outstanding because the Issuer or an Affiliate of the Issuer holds
the Note; however, Notes held by the Issuer or a Subsidiary of the Issuer shall
not be deemed to be outstanding for purposes of Section 3.07(b) hereof.

                                       31
<PAGE>

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

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

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

Section 2.09   Treasury Notes.

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

Section 2.10   Temporary Notes.

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

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

Section 2.11   Cancellation.

     The Issuer at any time may deliver Notes to the Trustee for cancellation.
The Registrar and Paying Agent shall forward to the Trustee any Notes
surrendered to them for registration of transfer, exchange or payment. The
Trustee and no one else shall cancel all Notes surrendered for registration of
transfer, exchange, payment, replacement or cancellation and shall dispose of
canceled Notes in accordance with its customary procedures. The Issuer may not
issue new Notes to replace Notes that it has paid or that have been delivered to
the Trustee for cancellation.

Section 2.12   Defaulted Interest.

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

Section 2.13   CUSIP Numbers.

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

                                  ARTICLE 3.
                           REDEMPTION AND PREPAYMENT

Section 3.01   Notices to Trustee.

     If the Issuer elects to redeem Notes pursuant to the optional redemption
provisions of Section 3.07 hereof, it shall furnish to the Trustee, at least 45
days but not more than 60 days before a redemption date, an Officer's
Certificate setting forth (i) the clause of this Indenture pursuant to which the
redemption shall occur, (ii) the redemption date, (iii) the principal amount of
Notes to be redeemed and (iv) the redemption price.

Section 3.02   Selection of Notes to Be Redeemed.

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

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

Section 3.03   Notice of Redemption.

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

     The notice shall identify the Notes (including CUSIP numbers, if any) to be
redeemed and shall state:

     (a)       the redemption date;

                                       33
<PAGE>

     (b)       the redemption price;

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

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

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

     (f)       that, unless the Issuer defaults in making such redemption
payment, interest on Notes called for redemption shall cease to accrue on and
after the redemption date;

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

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

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

Section 3.04   Effect of Notice of Redemption.

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

Section 3.05 Deposit of Redemption Price.

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

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

unredeemed portion of the Note surrendered.

     The Asset Sale Offer shall remain open for a period of 20 Business Days
following its commencement and no longer, except to the extent that a longer
period is required by applicable law (the "Offer Period"). No later than five
Business Days after the termination of the Offer Period (the "Purchase Date"),

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

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

     (a)  that the Asset Sale Offer is being made pursuant to this Section 3.09
and Section 4.10 hereof and the length of time the Asset Sale Offer shall remain
open;

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

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

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

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

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

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

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

     On or before the Purchase Date, the Issuer shall, to the extent lawful,
accept for payment, on a pro rata basis to the extent necessary, the Offer
Amount of Notes or portions thereof tendered pursuant to the Asset Sale Offer,
or if less than the Offer Amount has been tendered, all Notes tendered, and
shall deliver to the Trustee an Officer's Certificate stating that such Notes or
portions thereof were accepted for payment by the Issuer in accordance with the
terms of this Section 3.09. The Issuer, the Depositary or the Paying Agent, as
the case may be, shall promptly (but in any case not later than five days after
the

                                       36
<PAGE>

Purchase Date) mail or deliver to each tendering Holder an amount equal to
the purchase price of the Notes tendered by such Holder and accepted by the
Issuer for purchase, and the Issuer shall promptly issue a new Note, and the
Trustee, upon written request from the Issuer shall authenticate and mail or
deliver such new Note to such Holder, in a principal amount equal to any
unpurchased portion of the Note surrendered. Any Note not so accepted shall be
promptly mailed or delivered by the Issuer to the Holder thereof. The Issuer
shall publicly announce the results of the Asset Sale Offer on the Purchase
Date.

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

Subsidiary, as the case may be, pursuant to the Restricted Payment. The fair
market value of any assets or securities that are required to be valued pursuant
to this Section 4.07 shall be determined by the Board of Directors whose
resolution with respect thereto shall be delivered to the Trustee. The Board of
Directors' determination must be based upon an opinion or appraisal issued by an
accounting, appraisal or investment banking firm of national standing if the
fair market value exceeds $20.0 million. Not later than the date of making any
Restricted Payment, the Issuer shall deliver to the Trustee an Officer's

connection with or in anticipation of such acquisition), which encumbrance or
restriction is not applicable to any Person, or the properties or assets of any
Person, other than the Person, or the property or assets of the Person, so

restricts distributions by that Restricted Subsidiary pending its sale or other
disposition; (viii) Permitted Refinancing Indebtedness, provided that the
restrictions contained in the agreements governing such Permitted Refinancing
Indebtedness are no more restrictive, taken as a whole, than those contained in
the agreements governing the Indebtedness being refinanced; (ix) Liens securing
Indebtedness that limit the right of the debtor to dispose of the assets subject
to such Lien; (x) provisions with respect to the disposition or distribution of
assets or property in joint venture agreements, asset sale agreements, stock

Section 4.09   Incurrence of Indebtedness and Issuance of Preferred Stock.

     The Issuer shall not, and shall not permit any of its Subsidiaries to,
directly or indirectly, create, incur, issue, assume, guarantee or otherwise
become directly or indirectly liable, contingently or otherwise, with respect to
(collectively, "incur") any Indebtedness (including Acquired Debt) and the
Issuer shall not issue any Disqualified Stock and shall not permit any of its
Subsidiaries to issue any shares of preferred stock; provided, however, that the
Issuer may incur Indebtedness (including Acquired Debt) or issue shares of
Disqualified Stock, and Restricted Subsidiaries of the Issuer (other than

incur Indebtedness or issue preferred stock, if the Issuer's Adjusted Debt to
Cash Flow Ratio at the time of incurrence of such Indebtedness or the issuance
of such Disqualified Stock or preferred stock, after giving pro forma effect to
such incurrence or issuance as of such date and to the use of proceeds therefrom
as if the same had occurred at the beginning of the Issuer's most recently ended
fiscal quarter for which internal financial statements are available, would have
been no greater than 8.0 to 1.

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

Subsidiaries thereunder) not to exceed $1.75 billion;

          (ii)  the incurrence by the Issuer and its Wholly Owned Restricted

Credit Facilities if the Issuer's Adjusted Senior Debt to Cash Flow Ratio at the
time of the incurrence of such Indebtedness, after giving pro forma effect to
such incurrence, as of such date and to the use of proceeds therefrom as if the
same had occurred at the beginning of the Issuer's most recently ended fiscal
quarter for which internal financial statements are available, would have been
no greater than 5.5 to 1.0; provided that (i) any subsequent issuance or
transfer of Equity Interests that results in any such Indebtedness being held by
a Person other than the Issuer or one of its Restricted Subsidiaries and (ii)
any sale or other transfer of any such Indebtedness to a Person that is not
either the Issuer or one of its Restricted Subsidiaries will be deemed, in each
case, to constitute an incurrence of such Indebtedness by the Issuer or such
Restricted Subsidiary, as the case may be, that was not permitted by this clause
(ii);

          (iii) the incurrence of Indebtedness (including Acquired Debt) or the
issuance of preferred stock by Insight Midwest and its Restricted Subsidiaries
if Insight Midwest's Debt to Cash Flow Ratio at the time of incurrence of such
Indebtedness or the issuance of such preferred stock, after giving effect to
such incurrence or issuance, as of such date and to the use of proceeds
therefrom as if the same had occurred at the beginning of the most recently
ended fiscal quarter of Insight Midwest for which internal financial statements
are available, would have been no greater than 8.0 to 1.0;

          (iv)  the incurrence by the Issuer and its Restricted Subsidiaries of
the Existing Indebtedness;

                                       42
<PAGE>

          (v)    the incurrence by the Issuer of Indebtedness represented by the
Notes to be issued on the date of this Indenture and the Exchange Notes to be
issued pursuant to the Registration Rights Agreement;


          (vi)   the incurrence by the Issuer or any of its Restricted
Subsidiaries of Indebtedness represented by Capital Lease Obligations, mortgage
financings or purchase money obligations, in each case, incurred for the purpose
of financing all or any part of the purchase price or cost of construction or
improvement of property, plant or equipment used in the business of the Issuer
or such Restricted Subsidiary, in an aggregate principal amount, including all
Permitted Refinancing Indebtedness incurred to refund, refinance or replace any
Indebtedness incurred pursuant to this clause (vi), not to exceed $40.0 million
at any time outstanding;

          (vii)  the incurrence by the Issuer or any of its Restricted
Subsidiaries of Permitted Refinancing Indebtedness in exchange for, or the net
proceeds of which are used to refund, refinance or replace Indebtedness (other
than intercompany Indebtedness) that was permitted by this Indenture to be
incurred under the first paragraph of this Section 4.09 or clauses (ii), (iii),
(iv), (v) or (vi) of this paragraph;

          (viii) the incurrence by the Issuer or any of its Restricted
Subsidiaries of intercompany Indebtedness between or among the Issuer and any of
its Restricted Subsidiaries; provided, however, that: (a) the Issuer is the
obligor on such Indebtedness, such Indebtedness must be expressly subordinated
to the prior payment in full in cash of all Obligations with respect to the
Notes, and (b)(1) any subsequent issuance or transfer of Equity Interests that
results in any such Indebtedness being held by a Person other than the Issuer or
a Restricted Subsidiary thereof and (2) any sale or other transfer of any such
Indebtedness to a Person that is not either the Issuer or a Restricted
Subsidiary shall be deemed, in each case, to constitute an incurrence of such
Indebtedness by the Issuer or such Restricted Subsidiary, as the case may be,
that was not permitted by this clause (viii);

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

          (x)    the incurrence by the Issuer or any Restricted Subsidiary of
additional Indebtedness in an aggregate principal amount at any time outstanding
not to exceed 200% of the Capital Stock Sale Proceeds received by the Issuer
from the sale of its Equity Interests (other than Disqualified Stock) and (b)
the incurrence by Insight Midwest or any Restricted Subsidiary of Insight
Midwest of additional Indebtedness in an aggregate principal amount at any time
outstanding not to exceed 200% of the Capital Stock Sale Proceeds received by
Insight Midwest from the sale of its Equity Interests, (other than Disqualified
Stock), in either case, after the date of this Indenture to the extent such net
cash proceeds have not been applied to make Restricted Payments or to effect
other transactions pursuant to Section 4.07 hereof or to make Permitted
Investments pursuant to clause (6) of the definition thereof;

          (xi)   the guarantee by the Issuer of Indebtedness of the Issuer or a
Restricted Subsidiary of the Issuer that was permitted to be incurred by another
provision of this Section 4.09;

          (xii)  the accrual of interest, the accretion or amortization of
original issue discount, the payment of interest on any Indebtedness in the form
of additional Indebtedness with the same terms, and the payment of dividends on
Disqualified Stock in the form of additional shares of the same class of
Disqualified Stock will not be deemed to be an incurrence of Indebtedness or an
issuance of Disqualified Stock for purposes of this Section 4.09;

                                       43
<PAGE>

          (xiii) the incurrence by the Issuer or any of its Restricted
Subsidiaries of additional Indebtedness in an aggregate principal amount (or
accreted value, as applicable) at any time outstanding, including all Permitted
Refinancing Indebtedness incurred to refund, refinance or replace any
Indebtedness incurred pursuant to this clause (xiii), not to exceed $75.0
million;

          (xiv)  the incurrence by the Issuer or any Restricted Subsidiary of
Insight Midwest of Indebtedness represented by Notes issued to Affiliates in
respect of, and amounts equal to, advances made by such Affiliates to enable
Insight Midwest or any Restricted Subsidiary of Insight Midwest to make payments
in connection with the Notes, the 10 1/2% Notes and the 9 3/4% Notes or the
Credit Facilities; and

          (xv)   the incurrence by the Issuer's Unrestricted Subsidiaries of
Non-Recourse Debt, provided, however, that if any such Indebtedness ceases to be
Non-Recourse Debt of an Unrestricted Subsidiary, that event will be deemed to
constitute an incurrence of Indebtedness by a Restricted Subsidiary of the
Issuer that was not permitted by this clause (xv).

     The Issuer shall not, and shall not permit any of its Restricted
Subsidiaries to, incur any Indebtedness (including Permitted Debt) that is
contractually subordinated in right of payment to any other Indebtedness of the
Issuer or such Restricted Subsidiary, as applicable, unless such Indebtedness is
also contractually subordinated in right of payment to the Notes on
substantially identical terms; provided, however, that no Indebtedness of the
Issuer or a Restricted Subsidiary shall be deemed to be contractually
subordinated in right of payment to any other Indebtedness of the Issuer or such
Restricted Subsidiary solely by virtue of being unsecured.

     For purposes of determining compliance with this Section 4.09, in the event
that an item of Indebtedness meets the criteria of more than one of the
categories of Permitted Debt described in clauses (i) through (xv) above or is
entitled to be incurred pursuant to the first paragraph of this Section 4.09,
the Issuer shall, in its sole discretion, classify such item of Indebtedness in
any manner that complies with this Section 4.09 and such item of Indebtedness
shall be treated as having been incurred pursuant to only one of such clauses or
pursuant to the first paragraph of this Section 4.09. Accrual of interest shall
not be deemed to be an incurrence of Indebtedness for purposes of this Section
4.09. Indebtedness under Credit Facilities outstanding on the date on which
Notes are first issued and authenticated under this Indenture shall be deemed to
have been incurred on such date in reliance on the exception provided by clause
(i) of the definition of Permitted Debt.

Section 4.10   Asset Sales.

     The Issuer shall not, and shall not permit any of its Restricted
Subsidiaries to, consummate an Asset Sale, unless (x) the Issuer (or the
Restricted Subsidiary, as the case may be) receives consideration at the time of
such Asset Sale at least equal to the fair market value of the assets or Equity
Interests issued or sold or otherwise disposed of; (y) such fair market value is
determined by the Issuer's Board of Directors and evidenced by a resolution of
the Board of Directors set forth in an Officer's Certificate delivered to the
Trustee; and (z) at least 75% of the consideration received therefor by the
Issuer or such Restricted Subsidiary is in the form of cash or Cash Equivalents;
provided, however, that each of the following shall be deemed to be cash for
purposes of this provision: (A) any Indebtedness or other liabilities, as shown
on the Issuer's or such Restricted Subsidiary's most recent balance sheet, of
the Issuer or any Restricted Subsidiary (other than contingent liabilities and
Indebtedness that is by its terms subordinated to the Notes) that are assumed by
the transferee of any such assets pursuant to an agreement that releases the
Issuer or such Restricted Subsidiary from further liability; and (B) any
securities, Notes or other obligations received by the Issuer or any such
Restricted Subsidiary from such transferee that are converted within 45 days of
the applicable Asset Sale by the Issuer or such Restricted Subsidiary into cash,
to the extent of the cash received in that conversion.

                                       44
<PAGE>

     Notwithstanding the foregoing, the Issuer and its Restricted Subsidiaries
may engage in Asset Swaps; provided that, (i) immediately after giving effect to
such Asset Swap, the Issuer would be permitted to incur at least $1.00 of
additional Indebtedness pursuant to the Debt to Cash Flow Ratio test set forth
in the first paragraph of Section 4.09 hereof; and (ii) the Issuer's Board of
Directors determines that such Asset Swap is fair to the Issuer or such
Restricted Subsidiary, as the case may be, from a financial point of view and
such determination is evidenced by a resolution of the Board of Directors set
forth in an Officer's Certificate delivered to the Trustee.

     Within 365 days after the receipt of any Net Proceeds from an Asset Sale,
the Issuer may apply those Net Proceeds at its option: (a) to a permanent
repayment or reduction of Indebtedness (other than subordinated Indebtedness) of
the Issuer or a Restricted Subsidiary and, if the Indebtedness repaid is
revolving credit Indebtedness, to correspondingly reduce commitments with
respect thereto; (b) to acquire all or substantially all of the assets of a
Permitted Business; (c) to acquire Voting Stock of a Permitted Business from a
Person that is not a Subsidiary of the Issuer; provided, that (1) after giving
effect thereto, the Issuer and its Restricted Subsidiaries collectively own a
majority of such Voting Stock and (2) such acquisition is otherwise made in
accordance with this Indenture, including, without limitation Section 4.07
hereof; (d) to make capital expenditures; or (e) to acquire other long-term
tangible assets that are used or useful in a Permitted Business.

     Pending the final application of any Net Proceeds, the Issuer may
temporarily reduce revolving credit borrowings or otherwise invest the Net
Proceeds in any manner that is not prohibited by this Indenture. Any Net
Proceeds from Asset Sales that are not applied or invested as provided in the
first sentence of the immediately preceding paragraph will be deemed to
constitute "Excess Proceeds." Within five days of each date on which the
aggregate amount of Excess Proceeds exceeds $20.0 million, the Issuer will make
an Asset Sale Offer to all Holders of Notes and all holders of other
Indebtedness that is pari passu with the Notes containing provisions similar to
those set forth in this Indenture relating to the Notes with respect to offers
to purchase or redeem with the proceeds of sales of assets to purchase the
maximum principal amount of Notes and such other pari passu Indebtedness that
may be purchased out of the Excess Proceeds. The offer price in any Asset Sale
Offer will be equal to 100% of principal amount at maturity plus accrued and
unpaid interest and Liquidated Damages, if any, to the date of purchase (or, in
the case of purchases of notes prior to February 15, 2006, at 100% of the
Accreted Value thereof, plus Liquidated Damages thereon, if any, to the date of
purchase), and will be payable in cash. If any Excess Proceeds remain after
consummation of an Asset Sale Offer, the Issuer may use such Excess Proceeds for
any purpose not otherwise prohibited by this Indenture. If the aggregate
principal amount at maturity or Accreted Value (as applicable) of Notes and such
other pari passu Indebtedness tendered into such Asset Sale Offer exceeds the
amount of Excess Proceeds, the Trustee will select the Notes and such other pari
passu Indebtedness to be purchased on a pro rata basis based on the principal
amount at maturity or Accreted Value (as applicable) of notes and such other
pari passu Indebtedness tendered. Upon completion of each Asset Sale Offer, the
amount of Excess Proceeds will be reset at zero.

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

Section 4.11   Transactions with Affiliates.

     The Issuer shall not, and will not permit any of its Restricted
Subsidiaries to, directly or indirectly, make any payment to, or sell, lease,
transfer, exchange or otherwise dispose of any of its

                                       45
<PAGE>

properties or assets to, or purchase any property or assets from, or enter into
or make or amend any transaction or series of transactions, contract, agreement,
understanding, loan, advance or guarantee with, or for the benefit of, any
Affiliate, officer or director of the Issuer (each, an "Affiliate Transaction"),
unless: (a) such Affiliate Transaction is on terms that are no less favorable to
the Issuer or the relevant Restricted Subsidiary than those that would have been
obtained in a comparable transaction by the Issuer or such Restricted Subsidiary
with an unrelated Person (as determined by the Board of Directors and evidenced
by a resolution of the Board of Directors); and (b) the Issuer delivers to the
Trustee (i) with respect to any Affiliate Transaction or series of related
Affiliate Transactions involving aggregate consideration in excess of $10.0,
million, a resolution of the Board of Directors set forth in an Officer's
Certificate certifying that such Affiliate Transaction complies with clause (a)
above and that such Affiliate Transaction has been approved by a majority of the
disinterested members of the Board of Directors; and (ii) with respect to any
Affiliate Transaction or series of related Affiliate Transactions involving
aggregate consideration in excess of $20.0 million, an opinion as to the
fairness to the Issuer of such Affiliate Transaction from a financial point of
view issued by an accounting, appraisal or investment banking firm of national
standing; provided, however, that this clause (ii) shall not apply to any
transaction between or among the Issuer, Insight Midwest, AT&T Broadband, LLC
and their respective Subsidiaries; provided, however, that the following items
shall not be deemed to be Affiliate Transactions and, therefore, will not be
subject to the provisions of this Section 4.11: (i) any employment agreement
entered into by the Issuer or any of its Restricted Subsidiaries in the ordinary
course of business and consistent with the past practice of the Issuer or such
Restricted Subsidiary, (ii) transactions between or among the Issuer and/or its
Restricted Subsidiaries, (iii) transactions with a Person that is an Affiliate
of the Issuer solely because the Issuer owns an Equity Interest in such Person,
(iv) payment of reasonable directors fees to Persons who are not otherwise
Affiliates of the Issuer, (v) sales of Equity Interests (other than Disqualified
Stock) to Affiliates of the Issuer, (vi) Restricted Payments that are permitted
under Section 4.07 hereof; (vii) payment of management fees to Insight L.P.
pursuant to the Management Agreements, (viii) any transactions or arrangements
entered into, or payments made, pursuant to the terms of the Midwest Facility;
(ix) Permitted Investments; (x) any transactions or arrangements in existence on
the date hereof, including, without limitation, the Asset Contribution Agreement
and all such other agreements, amendments and documents as may be necessary or
desirable to perform and carry out the transactions contemplated by the Asset
Contribution Agreement; and (xi) any arrangement with affiliates of Source
Media, Inc. for the distribution of cable television services or programming.

Section 4.12  Liens.

     The Issuer shall not, and shall not permit any of its Restricted
Subsidiaries to, directly or indirectly create, incur, assume or suffer to exist
(collectively, "incur") any Lien of any kind on any asset now owned or hereafter
acquired, or any income or profits therefrom or assign or convey any right to
receive income therefrom, except Permitted Liens. The Issuer will not, and will
not permit any of its Restricted Subsidiaries to, directly or indirectly, incur
any Lien of any kind on or to otherwise pledge or grant any other interest in
the Capital Stock of Insight Midwest owned by the Issuer or any of its
Restricted Subsidiaries.

Section 4.13  Designation of Restricted and Unrestricted Subsidiaries

     The Board of Directors may designate any Restricted Subsidiary to be an
Unrestricted Subsidiary if that designation would not cause a Default. If a
Restricted Subsidiary is designated as an Unrestricted Subsidiary, the aggregate
fair market value of all outstanding Investments owned by the Issuer and its
Restricted Subsidiaries in the Subsidiary so designated shall be deemed to be an
Investment made as of the time of such designation and shall either reduce the
amount available for Restricted Payments under the first paragraph of Section
4.07 hereof or reduce the amount available for future Investments under one or
more clauses of the definition of Permitted Investments, as the Issuer shall
determine. That designation

                                       46
<PAGE>

shall only be permitted if such Investment would be permitted at that time and
if such Restricted Subsidiary otherwise meets the definition of an Unrestricted
Subsidiary. The Board of Directors may redesignate any Unrestricted Subsidiary
to be a Restricted Subsidiary if the redesignation would not cause a Default.

Section 4.14  Corporate Existence.

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

Section 4.15  Offer to Repurchase Upon Change of Control.

     (a)  Upon the occurrence of a Change of Control, the Issuer shall make an
offer (a "Change of Control Offer") to each Holder to repurchase all or any part
(equal to $1,000 or an integral multiple thereof) of each Holder's Notes at a
purchase price equal to 101% of the aggregate principal amount at maturity
thereof plus accrued and unpaid interest and Liquidated Damages thereon, if any,
to the date of purchase (or, in the case of repurchases of notes prior to
February 15, 2006, at 101% of the Accreted Value thereof, plus Liquidated
Damages thereon, if any, to the date of purchase) (the "Change of Control
Payment"). Within 30 days following any Change of Control, the Issuer shall mail
a notice to each Holder stating: (i) that the Change of Control Offer is being
made pursuant to this Section 4.15 and that all Notes tendered will be accepted
for payment; (ii) the purchase price and the purchase date, which shall be no
earlier than 30 and no later than 60 days from the date such notice is mailed
(the "Change of Control Payment Date"); (iii) that any Note not tendered will
continue to accrue interest; (iv) that, unless the Issuer defaults in the
payment of the Change of Control Payment, all Notes accepted for payment
pursuant to the Change of Control Offer shall cease to accrue interest after the
Change of Control Payment Date; (v) that Holders electing to have any Notes
purchased pursuant to a Change of Control Offer will be required to surrender
the Notes, with the form entitled "Option of Holder to Elect Purchase" on the
reverse of the Notes completed, to the Paying Agent at the address specified in
the notice prior to the close of business on the third Business Day preceding
the Change of Control Payment Date; (vi) that Holders will be entitled to
withdraw their election if the Paying Agent receives, not later than the close
of business on the second Business Day preceding the Change of Control Payment
Date, a facsimile transmission or letter setting forth the name of the Holder,
the principal amount of Notes delivered for purchase, and a statement that such
Holder is withdrawing his election to have the Notes purchased; and (vii) that
Holders whose Notes are being purchased only in part will be issued new Notes
equal in principal amount to the unpurchased portion of the Notes surrendered,
which unpurchased portion must be equal to $1,000 in principal amount or an
integral multiple thereof. The Issuer shall comply with the requirements of Rule
14e-1 under the Exchange Act and any other securities laws and regulations
thereunder to the extent such laws and regulations are applicable in connection
with the repurchase of Notes in connection with a Change of Control.

     (b)  On the Change of Control Payment Date, the Issuer shall, to the extent
lawful, (1) accept for payment all Notes or portions thereof properly tendered
pursuant to the Change of Control Offer, (2) deposit with the Paying Agent an
amount equal to the Change of Control Payment in respect of all Notes

                                       47
<PAGE>

or portions thereof so tendered and (3) deliver or cause to be delivered to the
Trustee the Notes so accepted together with an Officer's Certificate stating the
aggregate principal amount of Notes or portions thereof being purchased by the
Issuer. The Paying Agent shall promptly mail to each Holder of Notes so tendered
payment in an amount equal to the purchase price for the Notes, and the Trustee
shall promptly authenticate and mail (or cause to be transferred by book entry)
to each Holder a new Note equal in principal amount to any unpurchased portion
of the Notes surrendered by such Holder, if any; provided, that each such new
Note shall be in a principal amount of $1,000 or an integral multiple thereof.
The Issuer shall publicly announce the results of the Change of Control Offer on
or as soon as practicable after the Change of Control Payment Date.

     (c)  Notwithstanding anything to the contrary in this Section 4.15, the
Issuer shall not be required to make a Change of Control Offer upon a Change of
Control if a third party makes the Change of Control Offer in the manner, at the
times and otherwise in compliance with the requirements set forth in this
Section 4.15 and Section 3.09 hereof and all other provisions of this Indenture
applicable to a Change of Control Offer made by the Issuer and purchases all
Notes validly tendered and not withdrawn under such Change of Control Offer.

Section 4.16  Limitation on Sale and Leaseback Transactions.

     The Issuer shall not, and shall not permit any of its Restricted
Subsidiaries to, enter into any sale and leaseback transaction; provided that
the Issuer or any Restricted Subsidiary may enter into a sale and leaseback
transaction if: (i) the Issuer or that Restricted Subsidiary, as applicable,
could have (a) incurred Indebtedness in an amount equal to the Attributable Debt
relating to such sale and leaseback transaction under the Adjusted Debt to Cash
Flow Ratio test in the first paragraph, or the Debt to Cash Flow Ratio test set
forth in clause (iii) of the second paragraph, of Section 4.09 hereof and (b)
created a Lien on such property securing Attributable Debt pursuant to the
provisions of Section 4.12 hereof; (ii) the net cash proceeds of that sale and
leaseback transaction are at least equal to the fair market value, as determined
in good faith by the Board of Directors and set forth in an Officer's
Certificate delivered to the Trustee, of the property that is the subject of
that sale and leaseback transaction; and (iii) the transfer of assets in that
sale and leaseback transaction is permitted by, and the Issuer or that
Restricted Subsidiary applies the proceeds of such transaction in compliance
with, Section 4.10 hereof.

Section 4.17  Payments for Consent.

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

Section 4.18  Restrictions on Activities.

     The Issuer will not, and will not permit any of its Restricted Subsidiaries
to, engage in any business other than Permitted Businesses, except to such
extent as would not be material to the Issuer and its Restricted Subsidiaries,
taken as a whole.

Section 4.19  Calculation of Original Issue Discount

     The Issuer shall file with the Trustee promptly at the end of each calendar
year (i) a written notice specifying the amount of original issue discount
(including daily rates and accrual periods) accrued on Outstanding Securities as
of the end of such year and (ii) such other specific

                                       48
<PAGE>

information relating to such original issue discount as may then be relevant
under the Internal Revenue Code of 1986, as amended from time to time.

Section 5.01  Merger, Consolidation, or Sale of Assets.

     The Issuer shall not, directly or indirectly, consolidate or merge with or
into (whether or not the Issuer is the surviving entity), or sell, assign,
transfer, convey or otherwise dispose of all or substantially all of the
properties or assets of the Issuer and its Restricted Subsidiaries, taken as a
whole, in one or more related transactions to, another Person unless: (i)
either: (a) the Issuer is the surviving corporation; or (b) the Person formed by
or surviving any such consolidation or merger (if other than the Issuer) or to
which such sale, assignment, transfer, conveyance or other disposition shall
have been made is a corporation, limited liability company or limited
partnership organized or existing under the laws of the United States, any state
thereof or the District of Columbia; (ii) the Person formed by or surviving any
such consolidation or merger (if other than the Issuer) or the Person to which
such sale, assignment, transfer, conveyance or other disposition shall have been
made assumes all the obligations of the Issuer under the Notes, this Indenture
and the Registration Rights Agreement pursuant to agreements reasonably
satisfactory to the Trustee; (iii) immediately after such transaction no Default
or Event of Default exists; and (iv) the Issuer or the Person formed by or
surviving any such consolidation or merger (if other than the Issuer), or to
which such sale, assignment, transfer, conveyance or other disposition shall
have been made shall, on the date of such transaction after giving pro forma
effect thereto and any related financing transactions as if the same had
occurred at the beginning of the applicable fiscal quarter, be permitted to
incur at least $1.00 of additional Indebtedness pursuant to the Adjusted Debt to
Cash Flow Ratio test set forth in the first paragraph, or the Debt to Cash Flow
Ratio test set forth in clause (iii) of the second paragraph, of Section 4.09
hereof. In addition, the Issuer may not, directly or indirectly, lease all or
substantially all of its properties or assets, in one or more related
transactions, to any other Person. The provisions of this Section 5.01 shall not
apply to a sale, assignment, transfer, conveyance or other disposition of assets
between or among the Issuer and any of its Restricted Subsidiaries.

Section 5.02  Successor Corporation Substituted.

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

                             DEFAULTS AND REMEDIES

Section 6.01  Events of Default.

     An "Event of Default" occurs if:

     (a)  the Issuer defaults in the payment when due of interest on, or
Liquidated Damages with respect to, the Notes and such default continues for a
period of 30 days;

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

upon redemption (including in connection with an offer to purchase) or
otherwise;

amount of the Notes then outstanding voting as a single class;

     (e)  a default occurs under any mortgage, indenture or instrument under
which there may be issued or by which there may be secured or evidenced any
Indebtedness for money borrowed by the Issuer or any of its Restricted
Subsidiaries (or the payment of which is guaranteed by the Issuer or any of its
Restricted Subsidiaries), whether such Indebtedness or guarantee now exists, or
is created after the date of this Indenture, which default: (1) is caused by a
failure to pay principal of, or interest or premium, if any, on such
Indebtedness prior to the expiration of the grace period provided in such
Indebtedness on the date of such default (a "Payment Default"); or (2) results
in the acceleration of such Indebtedness prior to its express maturity and, in
each case, the principal amount of such Indebtedness, together with the
principal amount of any other such Indebtedness under which there has been a
Payment Default or the maturity of which has been so accelerated, aggregates
$25.0 million or more;

     (f)  the Issuer or any of its Restricted Subsidiaries fail to pay final

     (g)  the Issuer or any of its Significant Subsidiaries or any group of

pursuant to or within the meaning of Bankruptcy Law:

          (i)    commences a voluntary case,

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

<PAGE>

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

          (i)    is for relief against the Issuer or any of its Significant
Subsidiaries or any group of Subsidiaries that, taken as a whole, would
constitute a Significant Subsidiary in an involuntary case;

          (ii)   appoints a custodian of the Issuer or any of its Significant
Subsidiaries or any group of Subsidiaries that, taken as a whole, would
constitute a Significant Subsidiary or for all or substantially all of the
property of the Issuer or any of its Significant Subsidiaries or any group of
Subsidiaries that, taken as a whole, would constitute a Significant Subsidiary;
or

          (iii)  orders the liquidation of the Issuer or any of its Significant
Subsidiaries or any group of Subsidiaries that, taken as a whole, would
constitute a Significant Subsidiary; and the order or decree remains unstayed
and in effect for 60 consecutive days.

Section 6.02   Acceleration.

     If any Event of Default (other than an Event of Default specified in clause
(g) or (h) of Section 6.01 hereof with respect to the Issuer, any Significant
Subsidiary or any group of Significant Subsidiaries that, taken as a whole,
would constitute a Significant Subsidiary) occurs and is continuing, the Trustee
or the Holders of at least 25% in principal amount of the then outstanding Notes
may declare all the Notes to be due and payable immediately. Notwithstanding the
foregoing, if an Event of Default specified in clause (g) or (h) of Section 6.01
hereof occurs with respect to the Issuer, any of its Significant Subsidiaries or
any group of Subsidiaries that, taken as a whole, would constitute a Significant
Subsidiary, all outstanding Notes shall be due and payable immediately without
further action or notice. The Holders of a majority in aggregate principal
amount of the then outstanding Notes by written notice to the Trustee may on
behalf of all of the Holders rescind an acceleration and its consequences if the
rescission would not conflict with any judgment or decree and if all existing
Events of Default (except nonpayment of principal, interest or Liquidated
Damages, if any, that has become due solely because of the acceleration, and
with respect to any provision of this Indenture that cannot be modified or
amended without the consent of the Holder of each note affected thereby) have
been cured or waived.

     If an Event of Default occurs on or after February 15, 2006 by reason of
any willful action (or inaction) taken (or not taken) by or on behalf of the
Issuer with the intention of avoiding payment of the premium that the Issuer
would have had to pay if the Issuer then had elected to redeem the Notes
pursuant to Section 3.07 hereof, then, upon acceleration of the Notes, an
equivalent premium shall also become and be immediately due and payable, to the
extent permitted by law, anything in this Indenture or in the Notes to the
contrary notwithstanding. If an Event of Default occurs prior to February 15,
2006 by reason of any willful action (or inaction) taken (or not taken) by or on
behalf of the Issuer with the intention of avoiding the prohibition on
redemption of the Notes prior to such date, then, upon acceleration of the
Notes, an additional premium shall also become and be immediately due and
payable in an amount, for each of the years beginning on February 15 of the
years set forth below, as set forth below (expressed as a percentage of the
Accreted Value of the Notes on the date of payment that would otherwise be due
but for the provisions of this sentence):

----                                                                 ----------

2004...............................................................  110.209%
2005...............................................................  108.167%

Section 6.03  Other Remedies.

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

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

Section 6.04  Waiver of Past Defaults.

     Holders of not less than a majority in aggregate principal amount of the
then outstanding Notes by notice to the Trustee may on behalf of the Holders of
all of the Notes waive an existing Default or Event of Default and its
consequences hereunder, except a continuing Default or Event of Default in the
payment of the principal of, premium and Liquidated Damages, if any, or interest
on, the Notes (including in connection with an offer to purchase); provided,
however, that the Holders of a majority in aggregate principal amount of the
then outstanding Notes may rescind an acceleration and its consequences,
including any related payment default that resulted from such acceleration. Upon
any such waiver, such Default shall cease to exist, and any Event of Default
arising therefrom shall be deemed to have been cured for every purpose of this
Indenture; but no such waiver shall extend to any subsequent or other Default or
impair any right consequent thereon.

Section 6.05  Control by Majority.

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

Section 6.06  Limitation on Suits.

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

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

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

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

                                       52
<PAGE>

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

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

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

Section 6.07  Rights of Holders of Notes to Receive Payment.

     Notwithstanding any other provision of this Indenture, the right of any
Holder of a Note to receive payment of principal, premium and Liquidated
Damages, if any, and interest on the Note, on or after the respective due dates
expressed in the Note (including in connection with an offer to purchase), or to
bring suit for the enforcement of any such payment on or after such respective
dates, shall not be impaired or affected without the consent of such Holder.

Section 6.08  Collection Suit by Trustee.

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

Section 6.09  Trustee May File Proofs of Claim.

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

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

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

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

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

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

Section 6.11 Undertaking for Costs.

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

                                  ARTICLE 7.

Section 7.01  Duties of Trustee.

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

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

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

          (ii) in the absence of bad faith on its part, the Trustee may
conclusively rely, as to the truth of the statements and the correctness of the
opinions expressed therein, upon certificates or opinions furnished to the
Trustee and conforming to the requirements of this Indenture. However, in the
case of any certificates or opinions which by any provision hereof are
specifically required to be furnished to the

                                       54
<PAGE>

Trustee, the Trustee shall examine the certificates and opinions to determine
whether or not they conform to the requirements of this Indenture.

action, its own negligent failure to act, or its own willful misconduct, except

this Section;

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

takes or omits to take in good faith in accordance with a direction received by
it pursuant to Section 6.05 hereof.

risk its own funds or incur any liability. The Trustee shall be under no

request of any Holders, unless such Holder shall have offered to the Trustee
security and indemnity satisfactory to it against any loss, liability or
expense.

it except as the Trustee may agree in writing with the Issuer. Money held in

be genuine and to have been signed or presented by the proper Person. The
Trustee need not investigate any fact or matter stated in the document.

     (b)  Before the Trustee acts or refrains from acting, it may require an
Officer's Certificate or an Opinion of Counsel or both. The Trustee shall not be
liable for any action it takes or omits to take in good faith in reliance on

or powers vested in it by this Indenture at the request or direction of any of
the Holders unless such Holders shall have offered

                                       55
<PAGE>

to the Trustee security or indemnity satisfactory to it against the costs,
expenses and liabilities that might be incurred by it in compliance with such
request or direction.

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 Issuer, personally or by agent or attorney at
the sole cost of the Issuer and shall incur no liability or additional liability
of any kind by reason of such inquiry or investigation.

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

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

     (j)  The Trustee may request that the Issuer deliver an Officer's
Certificate setting forth the names of individuals and/or titles of officers
authorized at such time to take specified actions pursuant to this Indenture,

Officer's Certificate, including any person specified as so authorized in any
such certificate previously delivered and not superseded.

Section 7.03  Individual Rights of Trustee.

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

paid to the Issuer or upon the Issuer's direction under any provision of this
Indenture, it shall not be responsible for the use or application of any money
received by any Paying Agent other than the Trustee, and it shall not be
responsible for any statement or recital herein or any statement in the Notes or
any other document in connection with the sale of the Notes or pursuant to this
Indenture other than its certificate of authentication.

Section 7.05 Notice of Defaults.

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

                                       56
<PAGE>

occurs. Except in the case of a Default or Event of Default in payment of
principal of, premium, if any, or interest or Liquidated Damages, if any, on any
Note, the Trustee may withhold the notice if and so long as a committee of its
Responsible Officers in good faith determines that withholding the notice is in
the interests of the Holders of the Notes.

Section 7.06  Reports by Trustee to Holders of the Notes.

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

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

Section 7.07  Compensation and Indemnity.

     The Issuer shall pay to the Trustee from time to time such compensation as
shall be agreed in writing between the Issuer and the Trustee for its acceptance
of this Indenture and services hereunder. The Trustee's compensation shall not
be limited by any law on compensation of a trustee of an express trust. The
Issuer shall reimburse the Trustee promptly upon request for all reasonable
disbursements, advances and expenses incurred or made by it in addition to the
compensation for its services. Such expenses shall include the reasonable
compensation, disbursements and expenses of the Trustee's agents and counsel.

     The Issuer shall indemnify each of the Trustee and any predecessor Trustee
against any and all losses, liabilities, damages, claims or expenses including
taxes (other than taxes based on the income of the Trustee) incurred by it
arising out of or in connection with the acceptance or administration of its
duties under this Indenture, including the costs and expenses of enforcing this
Indenture against the Issuer (including this Section 7.07) and defending itself
against any claim (whether asserted by the Issuer or any Holder or any other
person) or liability in connection with the exercise or performance of any of
its powers or duties hereunder, except to the extent any such loss, liability or
expense may be attributable to its negligence or bad faith. The Trustee shall
notify the Issuer promptly of any claim for which it may seek indemnity. Failure
by the Trustee to so notify the Issuer shall not relieve the Issuer of its
obligations hereunder. The Issuer shall defend the claim and the Trustee shall
cooperate in the defense. The Trustee may have separate counsel and the Issuer
shall pay the reasonable fees and expenses of such counsel. The Issuer need not
pay for any settlement made without its consent, which consent shall not be
unreasonably withheld.

     The obligations of the Issuer under this Section 7.07 shall survive the
satisfaction and discharge of this Indenture.

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

                                       57
<PAGE>

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

     The Trustee shall comply with the provisions of TIA (S) 313(b)(2) to the
extent applicable.

Section 7.08  Replacement of Trustee.

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

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

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

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

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

     (d)  the Trustee becomes incapable of acting.

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

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

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

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

Section 7.09  Successor Trustee by Merger, etc.

     If the Trustee consolidates, merges or converts into, or transfers all or
substantially all of its corporate trust business to, another corporation, the

                                  ARTICLE 8.
                   LEGAL DEFEASANCE AND COVENANT DEFEASANCE

Section 8.01  Option to Effect Legal Defeasance or Covenant Defeasance.

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

Section 8.02 Legal Defeasance and Discharge.

     Upon the Issuer's exercise under Section 8.01 hereof of the option
applicable to this Section 8.02, the Issuer shall, subject to the satisfaction
of the conditions set forth in Section 8.04 hereof, be deemed to have been
discharged from its obligations with respect to all outstanding Notes on the
date the conditions set forth below are satisfied (hereinafter, "Legal
Defeasance"). For this purpose, Legal Defeasance means that the Issuer shall be
deemed to have paid and discharged the entire Indebtedness represented by the
outstanding Notes, which shall thereafter be deemed to be "outstanding" only for
the purposes of Section 8.05 hereof and the other Sections of this Indenture
referred to in (a) and (b) below, and to have satisfied all its other
obligations under such Notes and this Indenture (and the Trustee, on demand of
and at the expense of the Issuer, shall execute proper instruments acknowledging
the same), except for the following provisions which shall survive until
otherwise terminated or discharged hereunder: (a) the rights of Holders of
outstanding Notes to receive solely from the trust fund described in Section
8.04 hereof, and as more fully set forth in such Section, payments in respect of
the principal of, premium and Liquidated Damages, if any, and interest on such
Notes when such payments are due, (b) the Issuer's obligations with respect to
such Notes under Article 2 and Section 4.02 hereof, (c) the rights, powers,
trusts, duties and immunities of the Trustee hereunder and the Issuer's
obligations in connection therewith

                                       59
<PAGE>

and (d) this Article Eight. Subject to compliance with this Article Eight, the
Issuer may exercise its option under this Section 8.02 notwithstanding the prior
exercise of its option under Section 8.03 hereof.

Section 8.03   Covenant Defeasance.

        Upon the Issuer's exercise under Section 8.01 hereof of the option
applicable to this Section 8.03, the Issuer shall, subject to the satisfaction
of the conditions set forth in Section 8.04 hereof, be released from its
obligations under the covenants contained in Sections 4.07, 4.08, 4.09, 4.10,
4.11, 4.12, 4.13, 4.15, 4.16, 4.17 and 4.18 hereof and clause (iv) of Section
5.01 hereof with respect to the outstanding Notes on and after the date the
conditions set forth in Section 8.04 are satisfied (hereinafter, "Covenant
Defeasance"), and the Notes shall thereafter be deemed not "outstanding" for the
purposes of any direction, waiver, consent or declaration or act of Holders (and
the consequences of any thereof) in connection with such covenants, but shall
continue to be deemed "outstanding" for all other purposes hereunder (it being
understood that such Notes shall not be deemed outstanding for accounting
purposes). For this purpose, Covenant Defeasance means that, with respect to the
outstanding Notes, the Issuer may omit to comply with and shall have no
liability in respect of any term, condition or limitation set forth in any such
covenant, whether directly or indirectly, by reason of any reference elsewhere
herein to any such covenant or by reason of any reference in any such covenant
to any other provision herein or in any other document and such omission to
comply shall not constitute a Default or an Event of Default under Section 6.01
hereof, but, except as specified above, the remainder of this Indenture and such
Notes shall be unaffected thereby. In addition, upon the Issuer's exercise under
Section 8.01 hereof of the option applicable to this Section 8.03 hereof,
subject to the satisfaction of the conditions set forth in Section 8.04 hereof,
Sections 6.01(c) through 6.01(f) hereof shall not constitute Events of Default.

Section 8.04   Conditions to Legal or Covenant Defeasance.

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

        In order to exercise either Legal Defeasance or Covenant Defeasance:

        (a)    the Issuer must irrevocably deposit with the Trustee, in trust,
for the benefit of the Holders, cash in United States dollars, non-callable
Government Securities, or a combination thereof, in such amounts as will be
sufficient, in the opinion of a nationally recognized firm of independent public
accountants, to pay the principal of, premium and Liquidated Damages, if any,
and interest on the outstanding Notes on the stated maturity or on the
applicable redemption date, as the case may be and the Issuer must specify
whether the Notes are being defeased to maturity or to a particular redemption
date;

        (b)    in the case of an election under Section 8.02 hereof, the Issuer
shall have delivered to the Trustee an Opinion of Counsel in the United States
reasonably acceptable to the Trustee confirming that (A) the Issuer has received
from, or there has been published by, the Internal Revenue Service a ruling or
(B) since the date of this Indenture, there has been a change in the applicable
federal income tax law, in either case to the effect that, and based thereon
such Opinion of Counsel shall confirm that, the Holders of the outstanding Notes
will not recognize income, gain or loss for federal income tax purposes as a
result of such Legal Defeasance and will be subject to federal income tax on the
same amounts, in the same manner and at the same times as would have been the
case if such Legal Defeasance had not occurred;

        (c)    in the case of an election under Section 8.03 hereof, the Issuer
shall have delivered to the Trustee an Opinion of Counsel in the United States
reasonably acceptable to the Trustee confirming that the Holders of the
outstanding Notes will not recognize income, gain or loss for federal income tax
purposes as a result of such Covenant Defeasance and will be subject to federal
income tax on the same

                                       60
<PAGE>

amounts, in the same manner and at the same times as would have been the case if
such Covenant Defeasance had not occurred;

     (d)  no Default or Event of Default shall have occurred and be continuing
either: (a) on the date of such deposit (other than a Default or Event of
Default resulting from the borrowing of funds to be applied to such deposit) or
(b) insofar as Sections 6.01(g) or 6.01(h) hereof are concerned, at any time in
the period ending on the 91st day after the date of deposit;

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

     (f)  the Issuer shall have delivered to the Trustee an Opinion of Counsel
to the effect that, assuming no intervening bankruptcy of the Issuer between the
date of deposit and the 91st day following the deposit and assuming that no
Holder is an "insider" of the Issuer under applicable bankruptcy law, after the
91st day following the deposit, the trust funds will not be subject to the
effect of any applicable bankruptcy, insolvency, reorganization or similar laws
affecting creditors' rights generally;

     (g)  the Issuer shall deliver to the Trustee an Officer's Certificate
stating that the deposit was not made by the Issuer with the intent of
preferring the Holders over any other creditors of the Issuer or with the intent
of defeating, hindering, delaying or defrauding any other creditors of the
Issuer or others; and

     (h)  the Issuer shall deliver to the Trustee an Officer's Certificate and
an Opinion of Counsel, each stating that all conditions precedent relating to
the Legal Defeasance or the Covenant Defeasance have been complied with.

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

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

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

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

                                       61
<PAGE>

Section 8.06  Repayment to the Issuer.

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

Section 8.07  Reinstatement.

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

                                  ARTICLE 9.
                       AMENDMENT, SUPPLEMENT AND WAIVER

Section 9.01  Without Consent of Holders of Notes.

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

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

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

     (c)  to provide for the assumption of the Issuer's obligations to the
Holders of the Notes by a successor to the Issuer pursuant to Article 5 hereof;

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

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

                                       62
<PAGE>

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

Section 9.02  With Consent of Holders of Notes.

     Except as provided below in this Section 9.02, the Issuer and the Trustee
may amend or supplement this Indenture (including Section 3.09, 4.10 and 4.15
hereof) and the Notes with the consent of the Holders of at least a majority in
principal amount of the Notes then outstanding voting as a single class
(including consents obtained in connection with a tender offer or exchange offer
for, or purchase of, the Notes), and, subject to Sections 6.04 and 6.07 hereof,
any existing Default or Event of Default (other than a Default or Event of
Default in the payment of the principal of, premium, if any, or interest or
Liquidated Damages, if any, on the Notes, except a payment default resulting
from an acceleration that has been rescinded) or compliance with any provision
of this Indenture or the Notes may be waived with the consent of the Holders of
a majority in principal amount of the then outstanding Notes voting as a single
class (including consents obtained in connection with a tender offer or exchange
offer for, or purchase of, the Notes). Section 2.08 hereof shall determine which
Notes are considered to be "outstanding" for purposes of this Section 9.02.

     Upon the request of the Issuer accompanied by a resolution of its Boards of
Directors authorizing the execution of any such amended or supplemental
Indenture, and upon the filing with the Trustee of evidence satisfactory to the
Trustee of the consent of the Holders of Notes as aforesaid, and upon receipt by
the Trustee of the documents described in Section 9.06 hereof, the Trustee shall
join with the Issuer in the execution of such amended or supplemental Indenture
unless such amended or supplemental Indenture directly affects the Trustee's own
rights, duties or immunities under this Indenture or otherwise, in which case
the Trustee may in its discretion, but shall not be obligated to, enter into
such amended or supplemental Indenture.

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

     After an amendment, supplement or waiver under this Section becomes
effective, the Issuer shall mail to the Holders of Notes affected thereby a
notice briefly describing the amendment, supplement or waiver. Any failure of
the Issuer to mail such notice, or any defect therein, shall not, however, in
any way impair or affect the validity of any such amended or supplemental
Indenture or waiver. Subject to Sections 6.04 and 6.07 hereof, the Holders of a
majority in aggregate principal amount of the Notes then outstanding voting as a
single class may waive compliance in a particular instance by the Issuer with
any provision of this Indenture or the Notes. However, without the consent of
each Holder affected, an amendment or waiver under this Section 9.02 may not
(with respect to any Notes held by a non-consenting Holder):

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

     (b)  reduce the principal amount at maturity of or change the fixed
maturity of any Note or alter or waive any of the provisions with respect to the
redemption of the Notes except as provided above

                                       63
<PAGE>

with respect to Sections 3.09, 4.10 and 4.15 hereof or amend or modify the
calculation of Accreted Value so as to reduce the amount of the Accreted Value
of the Notes;

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

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

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

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

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

Section 9.03   Compliance with Trust Indenture Act.

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

Section 9.04   Revocation and Effect of Consents.

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

Section 9.05   Notation on or Exchange of Notes.

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

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

Section 9.06   Trustee to Sign Amendments, etc.

        The Trustee shall sign any amended or supplemental Indenture authorized
pursuant to this Article if the amendment or supplement does not adversely
affect the rights, duties, liabilities or immunities of the Trustee. The Issuer
may not sign an amendment or supplemental Indenture until the Boards of
Directors approve it. In executing any amended or supplemental indenture, the
Trustee shall be entitled to

                                       64
<PAGE>

receive and (subject to Section 7.01 hereof) shall be fully protected in relying
upon, in addition to the documents required by Section 10.04 hereof, an
Officer's Certificate and an Opinion of Counsel stating that the execution of
such amended or supplemental indenture is authorized or permitted by this
Indenture.

                                [Back of Note]
                    12 1/4% Senior Discount Notes due 2011

[Insert the Global Note Legend, if applicable pursuant to the provisions of the
Indenture]

[Insert the Private Placement Legend, if applicable pursuant to the provisions
of the Indenture]

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

     1. INTEREST. Insight Communications Holdings, Inc., a Delaware corporation
(the "Issuer"), promises to pay interest on the principal amount of this Note at
12 1/4% per annum from February 15, 2006 until maturity and shall pay the
Liquidated Damages payable pursuant to, and to the extent required by, Section 5
of the Registration Rights Agreement referred to below. No interest will accrue
on the Notes prior to February 15, 2006. Instead, the Accreted Value of each
note will increase (representing amortization of original issue discount)
between the date of original issuance and February 15, 2006, at a rate of 12
1/4% calculated on a semi-annual bond equivalent basis using a 360-day year
comprised of twelve 30-day months, such that the Accreted Value on February 15,
2006 will be equal to the full principal amount at maturity of the Notes.
Beginning on February, 2006, interest on the Notes will accrue at a rate of 12
1/4% per annum. The Issuer will pay interest and Liquidated Damages
semi-annually in arrears on February 15 and August 15 of each year, or if any
such day is not a Business Day, on the next succeeding Business Day (each an
"Interest Payment Date"). Interest on the Notes will accrue from the most recent
date to which interest has been paid or, if no interest has been paid, from
February 15, 2006; provided that if there is no existing Default in the payment
of interest, and if this Note is authenticated between a record date referred to
on the face hereof and the next succeeding Interest Payment Date, interest shall
accrue from such next succeeding Interest Payment Date; provided, further, that
the first Interest Payment Date shall be August 15, 2006. The Issuer shall pay
interest (including post-petition interest in any proceeding under any
Bankruptcy Law) on overdue principal and premium, if any, from time to time on
demand at a rate that is 1% per annum in excess of the rate then in effect; the
Issuer shall pay interest (including post-petition interest in any proceeding
under any Bankruptcy Law) on overdue installments of interest and Liquidated
Damages (without regard to any applicable grace periods) from time to time on
demand at the same rate to the extent lawful. Interest will be computed on the
basis of a 360-day year of twelve 30-day months.

     2. METHOD OF PAYMENT. The Issuer will pay interest on the Notes (except
defaulted interest) and Liquidated Damages to the Persons who are registered
Holders of Notes at the close of business on the February 1 or August 1 next
preceding the Interest Payment Date, even if such Notes are canceled after such
record date and on or before such Interest Payment Date, except as provided in
Section 2.12 of the Indenture with respect to defaulted interest. The Notes will
be payable as to principal, premium and Liquidated Damages, if any, and interest
at the office or agency of the Issuer maintained for such purpose within or
without the City and State of New York, or, at the option of the Issuer, payment
of interest and Liquidated Damages may be made by check mailed to the Holders at
their addresses set forth in the register of Holders, and provided that payment
by wire transfer of immediately available funds will be required with respect to
principal of and interest, premium and Liquidated Damages on, all Global Notes
and all other Notes the Holders of which shall have provided wire transfer
instructions to the Issuer or the Paying Agent. Such payment shall be in such
coin or currency of the United States of America as at the time of payment is
legal tender for payment of public and private debts.

                                     A1-2
<PAGE>

     3. PAYING AGENT AND REGISTRAR.  Initially, The Bank of New York, the
Trustee under the Indenture, will act as Paying Agent and Registrar. The Issuer
may change any Paying Agent or Registrar without notice to any Holder. The
Issuer or any of its Subsidiaries may act in any such capacity.

     4. INDENTURE. The Issuer issued the Notes under an Indenture dated as of
February 6, 2001 ("Indenture") among the Issuer and the Trustee. The terms of
the Notes include those stated in the Indenture and those made part of the
Indenture by reference to the Trust Indenture Act of 1939, as amended (15 U.S.
Code (S)(S) 77aaa-77bbbb). The Notes are subject to all such terms, and Holders
are referred to the Indenture and such Act for a statement of such terms. To the
extent any provision of this Note conflicts with the express provisions of the
Indenture, the provisions of the Indenture shall govern and be controlling. The
Notes are obligations of the Issuer limited to $400.0 million in aggregate
principal amount at maturity.

     5. OPTIONAL REDEMPTION.

     (a)  Except as set forth in subparagraph (b) of this Paragraph 5, the
Issuer shall not have the option to redeem the Notes prior to February 15, 2006.
Thereafter, the Issuer shall have the option to redeem the Notes, in whole or in
part, upon not less than 30 nor more than 60 days' notice, at the redemption
prices (expressed as percentages of principal amount) set forth below plus
accrued and unpaid interest and Liquidated Damages thereon, if any, to the
applicable redemption date, if redeemed during the twelve-month period beginning
on February 15 of the years indicated below:

Year                                                                  Percentage
----                                                                  ----------
2006.................................................................   106.125%
2007.................................................................   104.083%
2008.................................................................   102.042%
2009 and thereafter..................................................   100.000%

     (b)  Notwithstanding the provisions of subparagraph (a) of this Paragraph
5, at any time prior to February 15, 2004, the Issuer may redeem Notes with the
net proceeds of one or more Equity Offerings by the Issuer at a redemption price
equal to 112.25% of the Accreted Value thereof, plus Liquidated Damages, if any,
to the redemption date; provided that at least 65% in aggregate principal amount
at maturity of the Notes issued under the Indenture remain outstanding
immediately after the occurrence of any such redemption and that such redemption
occurs within 90 days of the date of the closing of any such Equity Offering.

     6. MANDATORY REDEMPTION.

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

     7. REPURCHASE AT OPTION OF HOLDER.

     (a)  If there is a Change of Control, the Issuer shall be required to make
an offer (a "Change of Control Offer") to repurchase all or any part (equal to
$1,000 or an integral multiple thereof) of each Holder's Notes at a purchase
price equal to 101% of the aggregate principal amount at maturity thereof plus
accrued and unpaid interest and Liquidated Damages thereon, if any, to the date
of purchase (or, in the case of repurchases of notes prior to February 15, 2006,
at 101% of the Accreted Value thereof, plus Liquidated Damages thereon, if any,
to the date of purchase) (the "Change of Control Payment"). Within 30 days
following any Change of Control, the Issuer shall mail a notice to each Holder
setting forth the procedures governing the Change of Control Offer as required
by the Indenture.

                                     A1-3
<PAGE>

     (b)  If the Issuer or any Restricted Subsidiary consummates any Asset
Sales, within five days of each date on which the aggregate amount of Excess
Proceeds exceeds $20.0 million, the Issuer shall commence an offer to all
Holders of Notes (an "Asset Sale Offer") pursuant to Section 3.09 of the
Indenture to purchase the maximum principal amount of Notes and pari passu
indebtedness that may be purchased out of the Excess Proceeds at an offer price
in cash in an amount equal to 100% of the principal amount at maturity thereof
plus accrued and unpaid interest and Liquidated Damages thereon, if any, to the
date fixed for the closing of such offer (or, in the case of purchases of notes
prior to February 15, 2006, at 100% of the Accreted Value thereof, plus
Liquidated Damages thereon, if any, to the date of purchase) in accordance with
the procedures set forth in the Indenture. To the extent that the aggregate
amount at maturity or Accreted Value (as applicable) of Notes tendered pursuant
to an Asset Sale Offer is less than the Excess Proceeds, the Issuer (or such
Restricted Subsidiary) may use such deficiency for any purpose not otherwise
prohibited by the Indenture. If the aggregate principal amount at maturity or
Accreted Value (as applicable) of Notes and other such pari passu indebtedness
surrendered by Holders thereof exceeds the amount of Excess Proceeds, the
Trustee shall select the Notes to be purchased on a pro rata basis. Holders of
Notes that are the subject of an offer to purchase will receive an Asset Sale
Offer from the Issuer prior to any related purchase date and may elect to have
such Notes purchased by completing the form entitled "Option of Holder to Elect
Purchase" on the reverse of the Notes.

     8.  NOTICE OF REDEMPTION. NOTICE OF REDEMPTION WILL BE mailed at least 30
days but not more than 60 days before the redemption date to each Holder whose
Notes are to be redeemed at its registered address. Notes in denominations
larger than $1,000 may be redeemed in part but only in whole multiples of
$1,000, unless all of the Notes held by a Holder are to be redeemed. On and
after the redemption date interest ceases to accrue on Notes or portions thereof
called for redemption.

     9.  DENOMINATIONS, TRANSFER, EXCHANGE. The Notes are in registered form
without coupons in denominations of $1,000 and integral multiples of $1,000. The
transfer of Notes may be registered and Notes may be exchanged as provided in
the Indenture. The Registrar and the Trustee may require a Holder, among other
things, to furnish appropriate endorsements and transfer documents and the
Issuer may require a Holder to pay any taxes and fees required by law or
permitted by the Indenture. The Issuer need not exchange or register the
transfer of any Note or portion of a Note selected for redemption, except for
the unredeemed portion of any Note being redeemed in part. Also, the Issuer need
not exchange or register the transfer of any Notes for a period of 15 days
before the mailing of a notice of redemption of Notes to be redeemed or during
the period between a record date and the corresponding Interest Payment Date.

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

     11. AMENDMENT, SUPPLEMENT AND WAIVER. Subject to certain exceptions, the
Indenture or the Notes may be amended or supplemented with the consent of the
Holders of at least a majority in principal amount of the then outstanding Notes
voting as a single class, and any existing default or compliance with any
provision of the Indenture or the Notes may be waived with the consent of the
Holders of a majority in principal amount of the then outstanding Notes voting
as a single class. Without the consent of any Holder of a Note, the Indenture or
the Notes may be amended or supplemented to cure any ambiguity, defect or
inconsistency, to provide for uncertificated Notes in addition to or in place of
certificated Notes, to provide for the assumption of the Issuer's obligations to
Holders of the Notes in case of a merger or consolidation, to make any change
that would provide any additional rights or benefits to the Holders of the Notes
or that does not adversely affect the legal rights under the Indenture of any
such Holder and to comply with the requirements of the SEC in order to effect or
maintain the qualification of the Indenture under the Trust Indenture Act.

                                     A1-4
<PAGE>

     12. DEFAULTS AND REMEDIES. Events of Default include: (i) default for 30
days in the payment when due of interest or Liquidated Damages on the Notes;
(ii) default in payment when due of principal of or premium, if any, on the
Notes when the same becomes due and payable at maturity, upon redemption
(including in connection with an offer to purchase) or otherwise, (iii) failure
by the Issuer to comply with Sections 3.09, 4.10, 4.15 or 5.01 of the Indenture;
(iv) failure by the Issuer for 30 days after notice to the Issuer by the Trustee
or to the Issuer and the Trustee by the Holders of at least 25% in principal
amount of the Notes then outstanding voting as a single class to comply with
certain other agreements in the Indenture or the Notes; (v) default under
certain other agreements relating to Indebtedness of the Issuer or its
Restricted Subsidiaries which default results in the acceleration of such
Indebtedness prior to its express maturity; (vi) certain final judgments for the
payment of money that remain undischarged for a period of 60 days; and (vii)
certain events of bankruptcy or insolvency with respect to the Issuer or any of
its Significant Subsidiaries. If any Event of Default occurs and is continuing,
the Trustee or the Holders of at least 25% in principal amount of the then
outstanding Notes may declare all the Notes to be due and payable.
Notwithstanding the foregoing, in the case of an Event of Default arising from
certain events of bankruptcy or insolvency, all outstanding Notes will become
due and payable without further action or notice. Holders may not enforce the
Indenture or the Notes except as provided in the Indenture. Subject to certain
limitations, Holders of a majority in principal amount of the then outstanding
Notes may direct the Trustee in its exercise of any trust or power. The Trustee
may withhold from Holders of the Notes notice of any continuing Default or Event
of Default (except a Default or Event of Default relating to the payment of
principal or interest) if it determines that withholding notice is in their
interest. The Holders of a majority in aggregate principal amount of the Notes
then outstanding by notice to the Trustee may on behalf of the Holders of all of
the Notes waive any existing Default or Event of Default and its consequences
under the Indenture except a continuing Default or Event of Default in the
payment of premium, principal, interest or Liquidated Damages on the Notes. The
Issuer is required to deliver to the Trustee annually a statement regarding
compliance with the Indenture, and the Issuer is required upon becoming aware of
any Default or Event of Default, to deliver to the Trustee a statement
specifying such Default or Event of Default.

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

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

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

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

     17. ADDITIONAL RIGHTS OF HOLDERS OF RESTRICTED GLOBAL NOTES AND RESTRICTED
DEFINITIVE NOTES. In addition to the rights provided to Holders of Notes under
the Indenture, Holders of Restricted Global Notes and Restricted Definitive
Notes shall have all the rights set forth in the Registration Rights Agreement
dated as of February 6, 2001 among the Issuer and the parties named on the
signature pages thereof (the "Registration Rights Agreement").

                                     A1-5

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

     19. GOVERNING LAW. This Note shall be governed by the internal law of the
State of New York, without giving effect to applicable principles of conflicts
of law to the extent that the application of the laws of another jurisdiction
would be required thereby.

charge a copy of the Indenture and/or the Registration Rights Agreement.

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

     1.  Interest. Insight Communications Holdings, Inc., a Delaware corporation
(the "Issuer"), promises to pay interest on the principal amount of this Note at
12 1/4% per annum from February 15, 2006 until maturity and shall pay the
Liquidated Damages payable pursuant to, and to the extent required by, Section 5
of the Registration Rights Agreement referred to below. No interest will accrue
on the Notes prior to February 15, 2006. Instead, the Accreted Value of each
Note will increase (representing amortization of original issue discount)
between the date of original issuance and February 15, 2006, at a rate of 12
1/4% calculated on a semi-annual bond equivalent basis using a 360-day year
comprised of twelve 30-day months, such that the Accreted Value on February 15,
2006 will be equal to the full principal amount at maturity of the Notes.
Beginning on February 15, 2006, interest on the Notes will accrue at a rate of
12 1/4% per annum The Issuer will pay interest and Liquidated Damages
semi-annually in arrears on February 15 and August 15 of each year, or if any
such day is not a Business Day, on the next succeeding Business Day (each an
"Interest Payment Date"). Interest on the Notes will accrue from the most recent
date to which interest has been paid or, if no interest has been paid, from
February 15, 2006; provided that if there is no existing Default in the payment
of interest, and if this Note is authenticated between a record date referred to
on the face hereof and the next succeeding Interest Payment Date, interest shall
accrue from such next succeeding Interest Payment Date; provided, further, that
the first Interest Payment Date shall be August 15, 2006. The Issuer shall pay
interest (including post-petition interest in any proceeding under any
Bankruptcy Law) on overdue principal and premium, if any, from time to time on
demand at a rate that is 1% per annum in excess of the rate then in effect; the
Issuer shall pay interest (including post-petition interest in any proceeding
under any Bankruptcy Law) on overdue installments of interest and Liquidated
Damages (without regard to any applicable grace periods) from time to time on
demand at the same rate to the extent lawful. Interest will be computed on the
basis of a 360-day year of twelve 30-day months.

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

     2.  Method of Payment. The Issuer will pay interest on the Notes (except
defaulted interest) and Liquidated Damages to the Persons who are registered
Holders of Notes at the close of business on the February 1 or August 1 next
preceding the Interest Payment Date, even if such Notes are canceled after such
record date and on or before such Interest Payment Date, except as provided in
Section 2.12 of the Indenture with respect to defaulted interest. The Notes will
be payable as to principal, premium and Liquidated Damages, if any, and interest
at the office or agency of the Issuer maintained for such purpose within or
without the City and State of New York, or, at the option of the Issuer, payment
of interest and Liquidated Damages may be made by check mailed to the Holders at
their addresses set forth in the register of Holders, and provided that payment
by wire transfer of immediately available funds will be required with respect to
principal of and interest, premium and Liquidated Damages on, all Global Notes

instructions to the Issuer or the

                                     A2-3
<PAGE>

Paying Agent. Such payment shall be in such coin or currency of the United
States of America as at the time of payment is legal tender for payment of
public and private debts.

     3. Paying Agent and Registrar.  Initially, The Bank of New York, the
Trustee under the Indenture, will act as Paying Agent and Registrar. The Issuer
may change any Paying Agent or Registrar without notice to any Holder. The
Issuer or any of its Subsidiaries may act in any such capacity.

     4. Indenture. The Issuer issued the Notes under an Indenture dated as of
February 6, 2001 ("Indenture") among the Issuer and the Trustee. The terms of
the Notes include those stated in the Indenture and those made part of the
Indenture by reference to the Trust Indenture Act of 1939, as amended (15 U.S.
Code (S)(S) 77aaa-77bbbb). The Notes are subject to all such terms, and Holders
are referred to the Indenture and such Act for a statement of such terms. To the
extent any provision of this Note conflicts with the express provisions of the
Indenture, the provisions of the Indenture shall govern and be controlling. The
Notes are obligations of the Issuer limited to $400.0 million in aggregate
principal amount at maturity.

     5.  Optional Redemption.

     (a)  Except as set forth in subparagraph (b) of this Paragraph 5, the
Issuer shall not have the option to redeem the Notes prior to February 15, 2006.
Thereafter, the Issuer shall have the option to redeem the Notes, in whole or in
part, upon not less than 30 nor more than 60 days' notice, at the redemption
prices (expressed as percentages of principal amount) set forth below plus
accrued and unpaid interest and Liquidated Damages thereon, if any, to the
applicable redemption date, if redeemed during the twelve-month period beginning
on February 15 of the years indicated below:

     Year                                                            Percentage
     ----                                                            ----------
     2006..........................................................   106.125%
     2007..........................................................   104.083%
     2008..........................................................   102.042%
     2009 and thereafter...........................................   100.000%


     (b)  Notwithstanding the provisions of subparagraph (a) of this Paragraph
5, at any time prior to February 15, 2004, the Issuer may redeem Notes with the
net proceeds of one or more Equity Offerings by the Issuer at a redemption price
equal to 112.25% of the Accreted Value thereof, plus Liquidated Damages, if any,
to the redemption date; provided that at least 65% in aggregate principal amount
at maturity of the Notes issued under the Indenture remain outstanding
immediately after the occurrence of any such redemption and that such redemption
occurs within 90 days of the date of the closing of any such Equity Offering.

     6.  Mandatory Redemption.

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

     7.  Repurchase at Option of Holder.

     (a)  If there is a Change of Control, the Issuer shall be required to make
an offer (a "Change of Control Offer") to repurchase all or any part (equal to
$1,000 or an integral multiple thereof) of each Holder's Notes at a purchase
price equal to 101% of the aggregate principal amount at maturity thereof plus
accrued and unpaid interest and Liquidated Damages thereon, if any, to the date
of purchase (or, in the case of repurchases of notes prior to February 15, 2006,
at 101% of the Accreted Value thereof, plus

                                     A2-4
<PAGE>

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

     (b)  If the Issuer or any Restricted Subsidiary consummates any Asset
Sales, within five days of each date on which the aggregate amount of Excess
Proceeds exceeds $20.0 million, the Issuer shall commence an offer to all
Holders of Notes (an "Asset Sale Offer") pursuant to Section 3.09 of the
Indenture to purchase the maximum principal amount of Notes and pari passu
indebtedness that may be purchased out of the Excess Proceeds at an offer price
in cash in an amount equal to 100% of the principal amount at maturity thereof
plus accrued and unpaid interest and Liquidated Damages thereon, if any, to the
date fixed for the closing of such offer (or, in the case of purchases of notes
prior to February 15, 2006, at 100% of the Accreted Value thereof, plus
Liquidated Damages thereon, if any, to the date of purchase) in accordance with
the procedures set forth in the Indenture. To the extent that the aggregate
amount at maturity or Accreted Value (as applicable) of Notes tendered pursuant
to an Asset Sale Offer is less than the Excess Proceeds, the Issuer (or such
Restricted Subsidiary) may use such deficiency for any purpose not otherwise
prohibited by the Indenture. If the aggregate principal amount at maturity or
Accreted Value (as applicable) of Notes and other such pari passu indebtedness
surrendered by Holders thereof exceeds the amount of Excess Proceeds, the
Trustee shall select the Notes to be purchased on a pro rata basis. Holders of
Notes that are the subject of an offer to purchase will receive an Asset Sale
Offer from the Issuer prior to any related purchase date and may elect to have
such Notes purchased by completing the form entitled "Option of Holder to Elect
Purchase" on the reverse of the Notes.

     8.  Notice of Redemption. Notice of redemption will be mailed at least 30
days but not more than 60 days before the redemption date to each Holder whose
Notes are to be redeemed at its registered address. Notes in denominations
larger than $1,000 may be redeemed in part but only in whole multiples of
$1,000, unless all of the Notes held by a Holder are to be redeemed. On and
after the redemption date interest ceases to accrue on Notes or portions thereof
called for redemption.

     9.  Denominations, Transfer, Exchange. The Notes are in registered form
without coupons in denominations of $1,000 and integral multiples of $1,000. The
transfer of Notes may be registered and Notes may be exchanged as provided in
the Indenture. The Registrar and the Trustee may require a Holder, among other
things, to furnish appropriate endorsements and transfer documents and the
Issuer may require a Holder to pay any taxes and fees required by law or
permitted by the Indenture. The Issuer need not exchange or register the
transfer of any Note or portion of a Note selected for redemption, except for
the unredeemed portion of any Note being redeemed in part. Also, the Issuer need
not exchange or register the transfer of any Notes for a period of 15 days
before the mailing of a notice of redemption of Notes to be redeemed or during
the period between a record date and the corresponding Interest Payment Date.

     This Regulation S Temporary Global Note is exchangeable in whole or part
for one or more Global Notes only (i) on or after the termination of the 40 day
restricted period (as defined in Regulation S) and (ii) upon presentation of
certificates (accompanied by an Opinion of Counsel, if applicable) required by
Article 2 of the Indenture. Upon exchange of this Regulation S Temporary Global
Note for one or more Global Notes, the Trustee shall cancel this Regulation S
Temporary Global Note.

     10. Persons Deemed Owners. The registered Holder of a Note may be treated
as its owner for all purposes.

     11. Amendment, Supplement and Waiver. Subject to certain exceptions, the
Indenture or the Notes may be amended or supplemented with the consent of the
Holders of at least a majority in principal amount of the then outstanding Notes
voting as a single class, and any existing default or compliance with

                                     A2-5
<PAGE>

any provision of the Indenture or the Notes may be waived with the consent of
the Holders of a majority in principal amount of the then outstanding Notes
voting as a single class. Without the consent of any Holder of a Note, the
Indenture or the Notes may be amended or supplemented to cure any ambiguity,
defect or inconsistency, to provide for uncertificated Notes in addition to or
in place of certificated Notes, to provide for the assumption of the Issuer's
obligations to Holders of the Notes in case of a merger or consolidation, to
make any change that would provide any additional rights or benefits to the
Holders of the Notes or that does not adversely affect the legal rights under
the Indenture of any such Holder and to comply with the requirements of the SEC
in order to effect or maintain the qualification of the Indenture under the
Trust Indenture Act.

     12. Defaults and Remedies. Events of Default include: (i) default for 30
days in the payment when due of interest or Liquidated Damages on the Notes;
(ii) default in payment when due of principal of or premium, if any, on the
Notes when the same becomes due and payable at maturity, upon redemption
(including in connection with an offer to purchase) or otherwise, (iii) failure
by the Issuer to comply with Sections 3.09, 4.10, 4.15 or 5.01 of the Indenture;
(iv) failure by the Issuer for 30 days after notice to the Issuer by the Trustee
or to the Issuer and the Trustee by the Holders of at least 25% in principal
amount of the Notes then outstanding voting as a single class to comply with
certain other agreements in the Indenture or the Notes; (v) default under
certain other agreements relating to Indebtedness of the Issuer or its
Restricted Subsidiaries which default results in the acceleration of such
Indebtedness prior to its express maturity; (vi) certain final judgments for the
payment of money that remain undischarged for a period of 60 days; and (vii)
certain events of bankruptcy or insolvency with respect to the Issuer or any of
its Significant Subsidiaries. If any Event of Default occurs and is continuing,
the Trustee or the Holders of at least 25% in principal amount of the then
outstanding Notes may declare all the Notes to be due and payable.
Notwithstanding the foregoing, in the case of an Event of Default arising from
certain events of bankruptcy or insolvency, all outstanding Notes will become
due and payable without further action or notice. Holders may not enforce the
Indenture or the Notes except as provided in the Indenture. Subject to certain
limitations, Holders of a majority in principal amount of the then outstanding
Notes may direct the Trustee in its exercise of any trust or power. The Trustee
may withhold from Holders of the Notes notice of any continuing Default or Event
of Default (except a Default or Event of Default relating to the payment of
principal or interest) if it determines that withholding notice is in their
interest. The Holders of a majority in aggregate principal amount of the Notes
then outstanding by notice to the Trustee may on behalf of the Holders of all of
the Notes waive any existing Default or Event of Default and its consequences
under the Indenture except a continuing Default or Event of Default in the
payment of premium, principal, interest or Liquidated Damages on the Notes. The
Issuer is required to deliver to the Trustee annually a statement regarding
compliance with the Indenture, and the Issuer is required upon becoming aware of
any Default or Event of Default, to deliver to the Trustee a statement
specifying such Default or Event of Default.

     13. Trustee Dealings with Issuer. The Trustee, in its individual or any
other capacity, may make loans to, accept deposits from, and perform services
for the Issuer or its Affiliates, and may otherwise deal with the Issuer or its
Affiliates, as if it were not the Trustee.

     14. No Recourse Against Others. A director, officer, employee, incorporator
or stockholder, of the Issuer, as such, shall not have any liability for any
obligations of the Issuer under the Notes or the Indenture or for any claim
based on, in respect of, or by reason of, such obligations or their creation.
Each Holder by accepting a Note waives and releases all such liability. The
waiver and release are part of the consideration for the issuance of the Notes.

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

                                     A2-6

and not as tenants in common), CUST (= Custodian), and U/G/M/A (= Uniform Gifts
to Minors Act).

     17. Additional Rights of Holders of Restricted Global Notes and Restricted
Definitive Notes. In addition to the rights provided to Holders of Notes under
the Indenture, Holders of Restricted Global Notes and Restricted Definitive
Notes shall have all the rights set forth in the Registration Rights Agreement
dated as of February 6, 2001 among the Issuer and the parties named on the
signature pages thereof (the "Registration Rights Agreement").

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

     19. GOVERNING LAW. This Note shall be governed by the internal law of the
State of New York, without giving effect to applicable principles of conflicts
of law to the extent that the application of the laws of another jurisdiction
would be required thereby.

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