usage. Each Note shall be dated the date of its authentication. The Notes shall
be in denominations of $1,000 and integral multiples thereof.

    The terms and provisions contained in the Notes shall constitute, and are

records of the Trustee and the Depositary or its nominee, as the case may be, in
connection with transfers of interest as hereinafter provided.

Trustee. The signature shall be conclusive evidence that the Note has been
authenticated under this Indenture.
<PAGE>

    The Trustee shall, upon a written order of the Issuers signed by an Officer
of each of the Issuers (an "Authentication Order"), authenticate Notes for
original issue up to the aggregate principal amount stated in paragraph 4 of the

exceed such amount except as provided in Section 2.07 hereof.

authenticate Notes. An authenticating agent may authenticate Notes whenever the
Trustee may do so. Each reference in this Indenture to authentication by the

same rights as an Agent to deal with Holders or an Affiliate of the Issuers.

Section 2.03.     Registrar and Paying Agent.

    The Issuers shall maintain an office or agency where Notes may be presented
for registration of transfer or for exchange ("Registrar") and an office or
agency where Notes may be presented for payment ("Paying Agent"). The Registrar

agents. The term "Registrar" includes any co-registrar and the term "Paying
Agent" includes any additional paying agent. The Issuers may change any Paying
Agent or Registrar without notice to any Holder. The Issuers shall notify the
Trustee in writing of the name and address of any Agent not a party to this
Indenture. If the Issuers fail to appoint or maintain another entity as
Registrar or Paying Agent, the Trustee shall act as such. The Issuers or any of
their Subsidiaries may act as Paying Agent or Registrar.

Depositary with respect to the Global Notes.

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

or a nominee of such successor Depositary. All Global Notes will be exchanged by
the Issuers for Definitive Notes if (i) the Issuers deliver to the Trustee
notice from the Depositary that it is unwilling or unable to continue to act as
Depositary or that it is no longer a clearing agency registered under the
Exchange Act and, in either case, a successor Depositary is not appointed by the
Issuers within 120 days after the date of such notice from the Depositary or
(ii) the Issuers in their sole discretion determine that the Global Notes (in
whole but not in part) should be exchanged for Definitive Notes and deliver a
written notice to such effect to the Trustee; provided that in no event shall
the Regulation S Temporary Global Note be exchanged by the Issuers for
Definitive Notes prior to (x) the expiration of the Restricted Period and (y)
the receipt by the Registrar of any certificates required pursuant to Rule
903(c)(3)(ii)(B) under the Securities Act. Upon the occurrence of either of the

        to the instructions from the Holder thereof.

         (f) Exchange Offer. Upon the occurrence of the Exchange Offer in
    accordance with the Registration Rights Agreement, the Issuers shall issue
    and, upon receipt of an Authentication Order in accordance with Section 2.02
    hereof, the Trustee shall authenticate (i) one or more Unrestricted Global

    they are not broker-dealers, (y) they are not participating in a
    distribution of the Exchange Notes and (z) they are not affiliates (as

    Notes, the Trustee shall cause the aggregate principal amount of the
    applicable Restricted Global Notes to be reduced accordingly, and the
    Issuers shall execute and the Trustee shall authenticate and deliver to the
    Persons designated by the Holders of Definitive Notes so accepted Definitive
    Notes in the appropriate principal amount.

         (g) Legends. The following legends shall appear on the face of all

        Note issued pursuant to subparagraphs (b)(iv), (c)(iii), (c)(iv),

NOR THE BENEFICIAL OWNERS OF THIS REGULATION S TEMPORARY GLOBAL NOTE SHALL BE

    (h) Cancellation and/or Adjustment of Global Notes. At such time as all
beneficial interests in a particular Global Note have been exchanged for
<PAGE>

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 Issuers
    shall execute and the Trustee shall authenticate Global Notes and Definitive
    Notes upon the Issuers' 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 Issuers may require payment of
    a sum sufficient to cover any transfer tax or similar governmental charge
    payable in connection therewith (other than any such transfer taxes or
    similar governmental charge payable upon exchange or transfer pursuant to
    Sections 2.10, 3.06, 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 Issuers, evidencing the same debt, and entitled to
    the same benefits under this Indenture, as the Global Notes or Definitive
    Notes surrendered upon such registration of transfer or exchange.

        (v) The Issuers shall not be required (A) to issue, to register the
    transfer of or to exchange any Notes during a period beginning at the
    opening of business 15 days before the day of any selection of Notes for
    redemption under Section 3.02 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 Issuers may deem and treat the Person
    in whose name any Note is registered as the absolute owner of such Note for
    the purpose of receiving payment of principal of and interest and Liquidated
    Damages, if any, on such Notes and for all other purposes, and none of the
    Trustee, any Agent or the Issuers shall be affected by notice to the
    contrary.



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

Section 2.07.     Replacement Notes.

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

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

Section 2.08.     Outstanding Notes.

    The Notes outstanding at any time are all the Notes authenticated by the
Trustee except for those canceled by it, those delivered to it for cancellation,
those reductions in the interest in a Global Note effected by the Trustee in
accordance with the provisions 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 Issuers or an Affiliate of the Issuers holds
the Note; however, Notes held by the Issuers or a Subsidiary of the Issuers
shall not be deemed to be outstanding for purposes of Section 3.07(b) hereof.

    If a Note is replaced pursuant to Section 2.07 hereof, it ceases to be
outstanding unless the Trustee receives proof satisfactory to it that the
replaced Note is held by a 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 either 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 Issuers,
or by any Person directly or indirectly controlling or controlled by or under
direct or indirect common control with the Issuers, 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 the Trustee knows are so owned shall be so disregarded.



Section 2.10.     Temporary Notes.

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

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

Section 2.11.     Cancellation.

    The Issuers at any time may deliver Notes to the Trustee for cancellation.
The Registrar and Paying Agent shall forward to the Trustee any Notes
surrendered to them for registration of transfer, exchange or payment. The
Trustee and no one else shall cancel all Notes surrendered for registration of
transfer, exchange, payment, replacement or cancellation and shall destroy
canceled Notes (subject to the record retention requirement of the Exchange
Act). Certification of the destruction of all canceled Notes shall be delivered
to the Issuers. The Issuers may not issue new Notes to replace Notes that they
have paid or that have been delivered to the Trustee for cancellation.

Section 2.12.     Defaulted Interest.

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

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 Issuers in writing of the Notes
selected for redemption and, in the case of any Note selected for partial
redemption, the principal amount thereof to be redeemed. Notes and portions of
Notes selected shall be in amounts of $1,000 or whole multiples of $1,000;
except that if all of the Notes of a Holder are to be redeemed, the entire
outstanding amount of Notes held by such Holder, even if not a multiple of
$1,000, shall be redeemed. Except as provided in the preceding sentence,
<PAGE>

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 Issuers shall mail or cause to
be mailed, by first class mail, a notice of redemption to each Holder whose
Notes are to be redeemed at its registered address.

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

    (a) the redemption date;

    (b) the redemption price;

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

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

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

    (f) that, unless the Issuers default in making such redemption payment,
interest on Notes called for redemption 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 Issuers' request, the Trustee shall give the notice of redemption in
the Issuers' name and at their expense; provided, however, that the Issuers
shall have delivered to the Trustee, at least 45 days prior to the redemption
date, an Officers' Certificate requesting that the Trustee give such notice and
setting forth the information 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 Issuers shall deposit
with the Trustee or with the Paying Agent money sufficient to pay the redemption
price of and accrued interest on all Notes to be redeemed on that date. The
Trustee or the Paying Agent shall promptly return to the Issuers any money
deposited with the Trustee or the Paying Agent by the Issuers in excess of the
amounts necessary to pay the redemption price of, and accrued interest on, all
Notes to be redeemed.

    If the Issuers comply with the provisions of the preceding paragraph, on and
after the redemption date, interest shall cease to accrue on the Notes or the
portions of Notes called for redemption. If a Note is redeemed on or after an
interest record date but on or prior to the related interest payment date, then
<PAGE>

any accrued and unpaid interest shall be paid to the Person in whose name such
Note was registered at the close of business on such record date. If any Note
called for redemption shall not be so paid upon surrender for redemption because
of the failure of the Issuers to comply with the preceding paragraph, interest
shall be paid on the unpaid principal, from the redemption date until such
principal is paid, and to the extent lawful on any interest not paid on such
unpaid principal, in each case at the rate provided in the Notes and in Section
4.01 hereof.

Section 3.06.     Notes Redeemed in Part.

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

Section 3.07.     Optional Redemption.

    (a) Except as set forth in clause (b) of this Section 3.07, the Issuers

any time prior to October 1, 2002, the Issuers may on one or more occasions
redeem Notes with the net proceeds of one or more Equity Offerings at a
redemption price equal to 109.75% of the aggregate principal amount thereof plus
accrued and unpaid Liquidated Damages thereon, if any, to the redemption date,

Offer"), it shall follow the procedures specified below.

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

the Issuers shall purchase the principal amount of Notes required to be
purchased pursuant to Section 4.10 hereof (the "Offer Amount") or, if less than
the Offer Amount has been tendered, all Notes tendered in response to the Asset
Sale Offer. Payment for any Notes so purchased shall be made in the same manner
as interest payments are made.

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

    (a) that the Asset Sale Offer is being made pursuant to this Section 3.09
and Section 4.10 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
accrue interest;

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

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

    (f) that Holders electing to have a Note purchased pursuant to any Asset
Sale Offer shall be required to surrender the Note, with the form entitled
"Option of Holder to Elect Purchase" on the reverse



of the Note completed, or transfer by book-entry transfer, to the Issuers, a
depositary, if appointed by the Issuers, or a Paying Agent at the address
specified in the notice at least three days before the Purchase Date;



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

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

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

    On or before the Purchase Date, the Issuers shall, to the extent lawful,
<PAGE>

accept for payment, on a pro rata basis to the extent necessary, the Offer
Amount of Notes or portions thereof tendered pursuant to the Asset Sale Offer,
or if less than the Offer Amount has been tendered, all Notes tendered, and
shall deliver to the Trustee an Officers' Certificate stating that such Notes or
portions thereof were accepted for payment by the Issuers in accordance with the
terms of this Section 3.09. The Issuers, the Depositary or the Paying Agent, as
the case may be, shall promptly (but in any case not later than five days after
the Purchase Date) mail or deliver to each tendering Holder an amount equal to
the purchase price of the Notes tendered by such Holder and accepted by the
Issuers for purchase, and the Issuers shall promptly issue a new Note, and the
Trustee, upon written request from the Issuers shall authenticate and mail or
deliver such new Note to such Holder, in a principal amount equal to any
unpurchased portion of the Note surrendered. Any Note not so accepted shall be
promptly mailed or delivered by the Issuers to the Holder thereof. The Issuers
shall publicly announce the results of the Asset Sale Offer on the Purchase
Date.

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

Section 4.01.     Payment of Notes.

    The Issuers shall pay or cause to be paid the principal of, premium, if
any, and interest on the Notes on the dates and in the manner provided in the
Notes. Principal, premium, if any, and interest shall be considered paid on the
date due if the Paying Agent, if other than an Issuer or a Subsidiary thereof,
holds as of 10:00 a.m. Eastern Time on the due date money deposited by the
Issuers in immediately available funds and designated for and sufficient to pay
all principal, premium, if any, and interest then due. The Issuers shall pay all
Liquidated Damages, if any, in the same manner on the dates and in the amounts
set forth in the Registration Rights Agreement.

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



any proceeding under any Bankruptcy Law) on overdue installments of interest and
Liquidated Damages (without regard to any applicable grace period) at the same
rate to the extent lawful.

Section 4.02.     Maintenance of Office or Agency.

    The Issuers shall maintain in the Borough of Manhattan, the City of New
York, an office or agency (which may be an office of the Trustee or an affiliate
of the Trustee, Registrar or co-registrar) where Notes may be surrendered for
registration of transfer or for exchange and where notices and demands to or
upon the Issuers in respect of the Notes and this Indenture may be served. The
Issuers shall give prompt written notice to the Trustee of the location, and any
change in the location, of such office or agency. If at any time the Issuers
shall fail to maintain any such required office or agency or shall fail to
furnish the Trustee with the address thereof, such presentations, surrenders,
notices and demands may be made or served at the Corporate Trust Office of the
Trustee.

    The Issuers may also from time to time designate one or more other offices
or agencies where the Notes may be presented or surrendered for any or all such
purposes and may from time to time rescind such designations; provided, however,
that no such designation or rescission shall in any manner relieve the Issuers
<PAGE>

of their obligation to maintain an office or agency in the Borough of Manhattan,
the City of New York for such purposes. The Issuers shall give prompt written
notice to the Trustee of any such designation or rescission and of any change in
the location of any such other office or agency.

    The Issuers hereby designate the Corporate Trust Office of the Trustee as
one such office or agency of the Issuers in accordance with Section 2.03 hereof.

Section 4.03.     Reports.

    (a) Whether or not required by the rules and regulations of the SEC, so long
as any Notes are outstanding, the Issuers shall furnish to the Holders of Notes:
(i) all quarterly and annual financial information that would be required to be
contained in a filing with the SEC on Forms 10-Q and 10-K if the Issuers were
required to file such forms, including a "Management's Discussion and Analysis
of Financial Condition and Results of Operations" and, with respect to the
annual information only, a report thereon by the Issuers' certified independent
accountants; and (ii) all current reports that would be required to be filed
with the SEC on Form 8-K if the Issuers were required to file such reports, in
each case, within the time periods specified in the SEC's rules and regulations.
In addition, following consummation of the Exchange Offer, whether or not
required by the rules and regulations of the SEC, the Issuers shall file a copy
of all such information and reports with the SEC for public availability within
the time periods specified in the SEC's rules and regulations (unless the SEC
will not accept such a filing) and make such information available to securities
analysts and prospective investors upon request. The Issuers shall at all times
comply with TIA ss. 314(a).

    (b) For so long as any Notes remain outstanding, the Issuers shall furnish
to the Holders and to securities analysts and prospective investors, upon their
request, the information required to be delivered pursuant to Rule 144A(d)(4)
under the Securities Act.

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



Section 4.04.     Compliance Certificate.

    (a) The Issuers shall deliver to the Trustee, within 90 days after the end
of each fiscal year, an Officers' Certificate stating that a review of the
activities of the Issuers and their Subsidiaries during the preceding fiscal
year has been made under the supervision of the signing Officers with a view to
determining whether the Issuers have kept, observed, performed and fulfilled
their obligations under this Indenture, and further stating, as to each such
Officer signing such certificate, that to the best of his or her knowledge the
Issuers have kept, observed, performed and fulfilled each and every covenant
contained in this Indenture and are not in default in the performance or
observance of any of the terms, provisions and conditions of this Indenture (or,
if a Default or Event of Default shall have occurred, describing all such
Defaults or Events of Default of which he or she may have knowledge and what
action the Issuers are taking or propose to take with respect thereto) and that
to the best of his or her knowledge no event has occurred and remains in
existence by reason of which payments on account of the principal of or
interest, if any, on the Notes is prohibited or if such event has occurred, a
description of the event and what action the Issuers are taking or propose to
take with respect thereto.
<PAGE>

    (b) So long as not contrary to the then current recommendations of the
American Institute of Certified Public Accountants, the year-end financial
statements delivered pursuant to Section 4.03(a) above shall be accompanied by a
written statement of the Issuers' independent public accountants (who shall be a
firm of established national reputation) that in making the examination
necessary for certification of such financial statements, nothing has come to
their attention that would lead them to believe that the Issuers have violated
any provisions of Article 4 or Article 5 hereof or, if any such violation has
occurred, specifying the nature and period of existence thereof, it being
understood that such accountants shall not be liable directly or indirectly to
any Person for any failure to obtain knowledge of any such violation.

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

Section 4.05.     Taxes.

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

Section 4.06.     Stay, Extension and Usury Laws.

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



Section 4.07.     Restricted Payments.

    The Issuers shall not, and shall not permit any of their Restricted
Subsidiaries to, directly or indirectly: (i) declare or pay any dividend or make
any other payment or distribution on account of the Issuers' or any of their
Restricted Subsidiaries' Equity Interests (including, without limitation, any
payment in connection with any merger or consolidation involving the Issuers or
any of their Restricted Subsidiaries) or to the direct or indirect holders of
the Issuers' or any of their Restricted Subsidiaries' Equity Interests in their
capacity as such (other than dividends or distributions payable in Equity
Interests (other than Disqualified Stock) of the Issuers or to the Issuers or a
Restricted Subsidiary of the Issuers); (ii) purchase, redeem or otherwise
acquire or retire for value (including, without limitation, in connection with
any merger or consolidation involving the Issuers) any Equity Interests of the
Issuers or any direct or indirect parent of the Issuers; (iii) make any payment
on or with respect to, or purchase, redeem, defease or otherwise acquire or
retire for value any Indebtedness that is subordinated to the Notes, except a
payment of interest or principal at the Stated Maturity thereof; or (iv) make
any Restricted Investment (all such payments and other actions set forth in
clauses (i) through (iv) above being collectively referred to as "Restricted
Payments"), unless, at the time of and after giving effect to such Restricted
Payment:

        (a) no Default or Event of Default shall have occurred and be continuing
<PAGE>

    or would occur as a consequence thereof; and

        (b) the Issuers would, at the time of such Restricted Payment and after
    giving pro forma effect thereto as if such Restricted Payment had been made
    at the beginning of the applicable fiscal quarter, have been permitted to
    incur at least $1.00 of additional Indebtedness (other than Permitted Debt)
    pursuant to the Debt to Cash Flow Ratio test set forth in the first
    paragraph of Section 4.09 hereof; and

        (c) such Restricted Payment, together with the aggregate amount of all
    other Restricted Payments declared or made after the date of this Indenture
    (excluding Restricted Payments made pursuant to clauses (ii), (iii) and (iv)
    of the next succeeding paragraph) shall not exceed, at the date of
    determination, the sum, without duplication, of: (i) an amount equal to the
    Issuers' Consolidated Cash Flow from the date of this Indenture to the end
    of the Issuers' most recently ended full fiscal quarter for which internal
    financial statements are available, taken as a single accounting period,
    less the product of 1.2 times the Issuers' Consolidated Interest Expense
    from the date of the indenture to the end of the Issuers' most recently
    ended full fiscal quarter for which internal financial statements are
    available, taken as a single accounting period; plus (ii) an amount equal to
    100% of Capital Stock Sale Proceeds less any such Capital Stock Sale
    Proceeds used in connection with: (1) an Investment made pursuant to clause
    (6) of the definition of "Permitted Investments;" or (2) an incurrence of
    Indebtedness pursuant to clause (8) of Section 4.09 hereof; plus (3) to the
    extent that any Restricted Investment that was made after the date of this
    Indenture is sold for cash or otherwise liquidated or repaid for cash, the
    lesser of: (A) the cash return of capital with respect to such Restricted
    Investment (less the cost of disposition, if any) and (B) the initial amount
    of such Restricted Investment; plus (4) to the extent that the Board of
    Directors designates any Unrestricted Subsidiary that was designated as such
    after the date of this Indenture as a Restricted Subsidiary, the lesser of
    (A) the aggregate fair market value of all Investments owned by the Issuers
    and their Restricted Subsidiaries in such Subsidiary at the time such
    Subsidiary was designated as an Unrestricted Subsidiary and (B) the then
    aggregate fair market value of all Investments owned by the Issuers and
    their Restricted Subsidiaries in such Unrestricted Subsidiary.

    So long as no Default has occurred and is continuing or would be caused
thereby, the preceding provisions shall not prohibit: (i) the payment of any
dividend within 60 days after the date of declaration



thereof, if at said date of declaration such payment would have complied with
the provisions of this Indenture; (ii) the redemption, repurchase, retirement,
defeasance or other acquisition of any subordinated Indebtedness of the Issuers
or of any Equity Interests of the Issuers in exchange for, or out of the net
cash proceeds of the substantially concurrent sale (other than to a Subsidiary
of the Issuers or an employee stock ownership plan or to a trust established by
the Issuers or any Subsidiary of the Issuers for the benefit of its employees)
of, Equity Interests of the Issuers (other than Disqualified Stock); provided
that the amount of any such net cash proceeds that are utilized for any such
redemption, repurchase, retirement, defeasance or other acquisition will be
excluded from clause (3)(b) of the preceding paragraph; (iii) the defeasance,
redemption, repurchase or other acquisition of subordinated Indebtedness of the
Issuers or any Restricted Subsidiary with the net cash proceeds from an
incurrence of Permitted Refinancing Indebtedness; (iv) regardless of whether any
Default then exists, the payment of any dividend by a Restricted Subsidiary of
an Issuer to the holders of its Equity Interests on a pro rata basis; (v) the
payment of any dividend or distribution to Insight Communications for the
repurchase, redemption or other acquisition or retirement for value by Insight
Communications of any Equity Interests of Insight Communications held by any
member of Insight Communications' (or any of its Subsidiaries') management
pursuant to any management equity subscription agreement or stock option
<PAGE>

agreement in effect as of the date of this Indenture; provided that the
aggregate price paid for all such repurchased, redeemed, acquired or retired
Equity Interests shall not exceed $1.0 million in any twelve-month period; (vi)
regardless of whether any Default then exists, the payment of any dividend or
distribution to the extent necessary to permit direct or indirect beneficial
owners of Capital Stock of the Company to pay federal, state or local income tax
liabilities that would arise solely from income of the Company or any of its
Restricted Subsidiaries, as the case may be, for the relevant taxable period and
attributable to them solely as a result of the Company (and any intermediate
entity through which the holder owns such Capital Stock) or any of its
Restricted Subsidiaries being a limited liability company, partnership or
similar entity for federal income tax purposes; (vii) the retirement, redemption
or repurchase of Equity Interests of an Issuer pursuant to clauses (ii) or (iii)
of Section 10.1(b) of the Partnership Agreement as a result of the occurrence of
a Formal Determination (as defined in the Partnership Agreement) and which
relates to Federal Communications Commission or other regulatory violations
described in the Partnership Agreement; and (viii) other Restricted Payments in
an aggregate amount not to exceed $25.0 million.

    The amount of all Restricted Payments (other than cash) shall be the fair
market value on the date of the Restricted Payment of the asset(s) or securities
proposed to be transferred or issued by the Issuers or such Restricted
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 Issuers shall deliver to the Trustee an Officers'
Certificate stating that such Restricted Payment is permitted and setting forth
the basis upon which the calculations required by this Section 4.07 were
computed, together with a copy of any fairness opinion or appraisal required by
this Indenture.

Section 4.08.    Dividend and Other Payment Restrictions Affecting Subsidiaries.

    The Issuers shall not, and shall not permit any of their Restricted
Subsidiaries to, directly or indirectly, create or permit to exist or become
effective any consensual encumbrance or restriction on the ability of any
Restricted Subsidiary to: (a) pay dividends or make any other distributions on
its Equity Interests to the Issuers or any of their Restricted Subsidiaries, or
with respect to any other interest or participation in, or measured by, its
profits, or pay any indebtedness owed to the Issuers or any of their Restricted
Subsidiaries; (b) make loans or advances or guarantee any such loans or advances
to the Issuers



or any of their Restricted Subsidiaries; or (c) transfer any of its properties
or assets to the Issuers or any of their Restricted Subsidiaries; except for
such encumbrances or restrictions existing under or by reasons of (i) Existing
Indebtedness as in effect on the date hereof and any amendments, modifications,
restatements, renewals, increases, supplements, refundings, replacements or
refinancings thereof, provided that such amendments, modifications,
restatements, renewals, increases, supplements, refundings, replacement or
refinancings are no more restrictive, taken as a whole, with respect to such
dividend and other payment restrictions than those contained in such Existing
Indebtedness, as in effect on the date hereof, (ii) this Indenture and the
Notes, (iii) applicable law, (iv) any instrument governing Indebtedness or
Capital Stock of a Person acquired by the Issuers or any of their Subsidiaries
as in effect at the time of such acquisition (except to the extent such
Indebtedness or Capital Stock was incurred in 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
<PAGE>

property or assets of the Person, so acquired, provided that in the case of
Indebtedness, such Indebtedness was permitted by the terms of this Indenture to
be incurred, (v) customary non-assignment provisions in leases entered into in
the ordinary course of business and consistent with past practices, (vi)
purchase money obligations for property acquired in the ordinary course of
business that impose restrictions of the nature described in clause (c) above on
the property so acquired, (vii) any agreement for the sale or other disposition
of a Restricted Subsidiary that 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 sale agreements and other
similar agreements entered into in the ordinary course of business; (xi)
restrictions on cash or other deposits or net worth imposed by customers under
contracts entered into in the ordinary course of business; (xii) restrictions
contained in the terms of Indebtedness permitted to be incurred under Section
4.09 hereof; provided that such restrictions are no more restrictive than the
terms contained in the Amended Kentucky Credit Facility and the Amended Indiana
Credit Facility; and (xiii) restrictions that are not materially more
restrictive than customary provisions in comparable financings and the
management of the Issuers determines that such restrictions will not materially
impair the Issuers' ability to make payments as required under this Indenture
and the Notes.

Section 4.09.     Incurrence of Indebtedness and Issuance of Preferred Stock.

    The Issuers shall not, and shall not permit any of their 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
Issuers shall not issue any Disqualified Stock and shall not permit any of their
Subsidiaries to issue any shares of preferred stock; provided, however, that the
Issuers may incur Indebtedness (including Acquired Debt) or issue shares of
Disqualified Stock, and Restricted Subsidiaries of the Issuers may incur
Indebtedness or issue preferred stock, if the Issuers' 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 most recently ended fiscal
quarter of the Issuers 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,
"Permitted Debt"):

        (i) the incurrence by the Issuers and their Restricted Subsidiaries of
    additional Indebtedness and letters of credit under Credit Facilities in an
    aggregate principal amount at any

    one time outstanding under this clause (i) (with letters of credit being
    deemed to have a principal amount equal to the maximum potential liability
    of the Issuers and their Restricted Subsidiaries thereunder) not to exceed
    $1.225 billion;

        (ii) the incurrence by the Issuers and their Restricted Subsidiaries of
    the Existing Indebtedness;

        (iii) the incurrence by the Issuers 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;

        (iv) the incurrence by the Issuers or any of their 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 Issuers 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 (iv), not to exceed $25.0 million at any time outstanding;

        (v) the incurrence by the Issuers or any of their 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) or (iv) of this paragraph;

        (vi) the incurrence by the Issuers or any of their Restricted
    Subsidiaries of intercompany Indebtedness between or among the Issuers and
    any of their Restricted Subsidiaries; provided, however, that: (a) if any of
    the Issuers 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 Issuers or a Restricted Subsidiary thereof
    and (2) any sale or other transfer of any such Indebtedness to a Person that
    is not either the Issuers or a Restricted Subsidiary of the Issuers shall be
    deemed, in each case, to constitute an incurrence of such Indebtedness by
    the Issuers or such Restricted Subsidiary, as the case may be, that was not
    permitted by this clause (vi);

        (vii) the incurrence by the Issuers or any of their 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;

        (viii) the incurrence by the Issuers or any Restricted Subsidiary of
    additional Indebtedness in an aggregate principal amount at any time
    outstanding not to exceed 200% of the net cash proceeds received by the
    Company from the sale of its Equity Interests, (other than Disqualified
    Stock), after the 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;

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



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

        (xi) the incurrence by the Issuers or any of their 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 (xi), not to exceed $50.0
<PAGE>

    million;

        (xii) the incurrence by the Issuers or any Restricted Subsidiary of
    Indebtedness represented by Notes issued to Affiliates in respect of, and
    amounts equal to, advances made by such Affiliates to enable the Issuers or
    any Restricted Subsidiary to make payments in connection with the Notes or
    the Amended Kentucky Credit Facility; and

        (xiii) the incurrence by the Issuers' 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 Issuers that was not permitted by this clause (xiii).

    The Issuers shall not, and shall not permit any of their Restricted
Subsidiaries to, incur any Indebtedness (including Permitted Debt) that is
contractually subordinated in right of payment to any other Indebtedness of the
Issuers 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
Issuers or a Restricted Subsidiary shall be deemed to be contractually
subordinated in right of payment to any other Indebtedness of the Issuers 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 (xiii) above or is
entitled to be incurred pursuant to the first paragraph of this Section 4.09,
the Issuers shall, in their 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 Issuers shall not, and shall not permit any of their Restricted
Subsidiaries to, consummate an Asset Sale, unless (x) the Issuers (or the
Restricted Subsidiary, as the case may be) receive 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 Issuers' Boards of Directors and evidenced by a resolution of
the Boards of Directors set forth in an Officers' Certificate delivered to the
Trustee; and (y) at least 75% of the consideration received therefor by the
Issuers 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 Issuers' or such Restricted Subsidiary's most recent balance
sheet, of the



Issuers 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
Issuers or such Restricted Subsidiary from further liability; and (B) any
securities, Notes or other obligations received by the Issuers or any such
Restricted Subsidiary from such transferee that are converted within 45 days of
the applicable Asset Sale by the Issuers or such Restricted Subsidiary into
cash, to the extent of the cash received in that conversion.
<PAGE>

    Notwithstanding the foregoing, the Issuers and their Restricted Subsidiaries
may engage in Asset Swaps; provided that, (i) immediately after giving effect to
such Asset Swap, the Issuers 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 Issuers' or the
Restricted Subsidiary's Board of Directors, as the case may be, determines that
such Asset Swap is fair to the Issuers or such Restricted Subsidiary, as the
case may be, from a financial point of view and such determination is evidenced
by a resolution of such Board of Directors set forth in an Officers' Certificate
delivered to the Trustee.

    Within 365 days after the receipt of any Net Proceeds from an Asset Sale,
the Issuers may apply those Net Proceeds at their option: (a) to a permanent
repayment or reduction of Indebtedness (other than subordinated Indebtedness) of
the Issuers 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 Issuers; provided, that (1) after giving
effect thereto, the Issuers and their 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 Issuers 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 Issuers 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 plus accrued and unpaid interest
and Liquidated Damages, 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 Issuers may use such Excess Proceeds for any purpose not otherwise
prohibited by this Indenture. If the aggregate principal amount of Notes and
such other pari passu Indebtedness tendered into such Asset Sale Offer exceeds
the amount of Excess Proceeds, the Trustee will select the Notes and such other
pari passu Indebtedness to be purchased on a pro rata basis based on the
principal amount 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 Issuers 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 Issuers shall comply with the applicable
securities laws and regulations and shall not be deemed to



have breached their obligations under the Asset Sale provisions of this
Indenture by virtue of such conflict.

Section 4.11.     Transactions with Affiliates.
<PAGE>

    The Issuers shall not, and will not permit any of their Restricted
Subsidiaries to, directly or indirectly, make any payment to, or sell, lease,
transfer, exchange or otherwise dispose of any of their 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 Issuers (each, an "Affiliate Transaction"), unless: (a) such
Affiliate Transaction is on terms that are no less favorable to the Issuers or
the relevant Restricted Subsidiary than those that would have been obtained in a
comparable transaction by the Issuers 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 Issuers deliver 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 Officers'
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 Issuers 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 Company, Insight Communications,
Tele-Communications, Inc. 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 Issuers or any of their Restricted
Subsidiaries in the ordinary course of business and consistent with the past
practice of the Issuers or such Restricted Subsidiary, (ii) transactions between
or among the Issuers and/or their Restricted Subsidiaries, (iii) transactions
with a Person that is an Affiliate of the Issuers solely because an Issuer owns
an Equity Interest in such Person, (iv) payment of reasonable directors fees to
Persons who are not otherwise Affiliates of the Issuers, (v) sales of Equity
Interests (other than Disqualified Stock) to Affiliates of the Issuers, (vi)
Restricted Payments that are permitted under Section 4.07 hereof; (vii) payment
of management fees to Insight Communications Company, L.P. pursuant to the
Management Agreements, (viii) any transactions or arrangements entered into, or
payments made, pursuant to the terms of the Amended Kentucky Credit Facility or
the Amended Indiana Credit Facility, (ix) Permitted Investments, (x) any
transactions or arrangements in existence on the date hereof; and (xi) any
arrangement with affiliates of Source Media, Inc. for the distribution of cable
television services or programming.

Section 4.12.     Liens.

    The Issuers shall not, and shall not permit any of their Restricted
Subsidiaries to, directly or indirectly create, incur, assume or suffer to exist
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.

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 Issuers and their
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
<PAGE>

the amount available for future Investments under one or more clauses of the
definition of Permitted Investments, as the Issuers shall determine. That
designation 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 Issuers shall do or cause to be done all
things necessary to preserve and keep in full force and effect (i) their
corporate and limited liability company existence, as applicable, and the
corporate, limited liability company, partnership or other existence of each of
their Subsidiaries, in accordance with the respective organizational documents
(as the same may be amended from time to time) of the Issuers or any such
Subsidiary and (ii) the rights (charter and statutory), licenses and franchises
of the Issuers and their Subsidiaries; provided, however, that the Issuers 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
their Subsidiaries, if the Board of Directors shall determine that the
preservation thereof is no longer desirable in the conduct of the business of
the Issuers and their 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 Issuers shall make an
offer (a "Change of Control Offer") to each Holder to repurchase all or any part
(equal to $1,000 or an integral multiple thereof) of each Holder's Notes at a
purchase price equal to 101% of the aggregate principal amount thereof plus
accrued and unpaid interest and Liquidated Damages thereon, if any, to the date
of purchase (the "Change of Control Payment"). Within 30 days following any
Change of Control, the Issuers 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 Issuers default in the payment of the Change of Control Payment, all
Notes accepted for payment pursuant to the Change of Control Offer shall cease
to accrue interest after the Change of Control Payment Date; (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 Issuers 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 Issuers shall, to the extent
lawful, (1) accept for payment all Notes or portions thereof properly tendered
<PAGE>

pursuant to the Change of Control Offer, (2) deposit with the Paying Agent an
amount equal to the Change of Control Payment in respect of all Notes or
portions thereof so tendered and (3) deliver or cause to be delivered to the
Trustee the Notes so accepted together with an Officers' Certificate stating the
aggregate principal amount of Notes or portions thereof being purchased by the
Issuers. 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 Issuers 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
Issuers shall not be required to make a Change of Control Offer upon a Change of
Control if a third party makes the Change of Control Offer in the manner, at the
times and otherwise in compliance with the requirements set forth in this
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 Issuers 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 Issuers shall not, and shall not permit any of their Restricted
Subsidiaries to, enter into any sale and leaseback transaction; provided that
the Issuers or any Restricted Subsidiary may enter into a sale and leaseback
transaction if: (i) the Issuers 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 Debt to Cash Flow
Ratio test in the first 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 Officers' 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 Issuers or that Restricted
Subsidiary applies the proceeds of such transaction in compliance with, Section
4.10 hereof.

Section 4.17.     Payments for Consent.

    The Issuers shall not, and shall not permit any of their 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 of Insight Capital.

    Insight Capital shall not hold any material assets, become liable for any
material obligations other than the Notes, or engage in any significant business
activities; provided that Insight Capital may be a co-obligor with respect to
Indebtedness if the Company is a primary obligor of such Indebtedness and the
net proceeds of such Indebtedness are received by the Company or one or more of
the Company's Restricted Subsidiaries other than Insight Capital.

                                   SUCCESSORS
<PAGE>

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

    No Issuer shall, directly or indirectly, consolidate or merge with or
into (whether or not such 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 Issuers and their Restricted Subsidiaries, taken as
a whole, in one or more related transactions to, another Person unless: (i)
either: (a) such Issuer is the surviving corporation; or (b) the Person formed
by or surviving any such consolidation or merger (if other than such Issuer) or
to which such sale, assignment, transfer, conveyance or other disposition shall
have been made is a 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 such Issuer) or the Person to which
such sale, assignment, transfer, conveyance or other disposition shall have been
made assumes all the obligations of the Issuers 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 Issuers or the Person formed by or
surviving any such consolidation or merger (if other than the Issuers), 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 Debt to Cash
Flow Ratio test set forth in the first paragraph of Section 4.09 hereof. In
addition, the Issuers may not, directly or indirectly, lease all or
substantially all of their 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 Issuers and any of their 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
Issuers in accordance with Section 5.01 hereof, the successor corporation formed
by such consolidation or into or with which an 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 "Issuers" shall refer instead to
the successor corporation and not to the applicable Issuer), and may exercise
every right and power of the Issuers under this Indenture with the same effect
as if such successor Person had been named as an Issuer herein; provided,
however, that the predecessor Issuers 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 an Issuer's
assets that meets the requirements of Section 5.01 hereof.

                                   ARTICLE 6.
                              DEFAULTS AND REMEDIES

Section 6.01.     Events of Default.

    An "Event of Default" occurs if:

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



    (b) the Issuers default in the payment when due of principal of or premium,
<PAGE>

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;

    (c) the Issuers fail to comply with any of the provisions of Section 3.09,
4.10, 4.15 or 5.01 hereof;

    (d) the Issuers or any of their Restricted Subsidiaries fail to comply with
any other covenant, representation, warranty or other agreement in this
Indenture for 30 days after written notice to the Issuers by the Trustee or to
the Issuers and the Trustee by the Holders of at least 25% in aggregate
principal amount of the Notes (including Additional Notes, if any) then
outstanding voting as a single class;

    (e) a default occurs under any mortgage, indenture or instrument under which
there may be issued or by which there may be secured or evidenced any
Indebtedness for money borrowed by the Issuers or any of their Restricted
Subsidiaries (or the payment of which is guaranteed by the Issuers or any of
their 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 Issuers or any of their Restricted Subsidiaries fail to pay final
judgments which are non-appealable aggregating in excess of $25.0 million, (net
of applicable insurance which has not been denied in writing by the insurer),
which judgments are not paid, discharged or stayed for a period of 60 days;

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

        (i) commences a voluntary case,

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

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

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

        (v) generally is not paying its debts as they become due; or

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

        (i) is for relief against the Issuers or any of their 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 Issuers or any of their 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 Issuers or any of their Significant Subsidiaries or any
    group of Subsidiaries that, taken as a whole, would constitute a Significant
    Subsidiary; or
<PAGE>

        (iii) orders the liquidation of the Issuers or any of their 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 Issuers, 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 Issuers, any of their 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 October 1, 2004 by reason of any
willful action (or inaction) taken (or not taken) by or on behalf of the Issuers
with the intention of avoiding payment of the premium that the Issuers would
have had to pay if the Issuers 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 October 1, 2004 by reason of any willful
action (or inaction) taken (or not taken) by or on behalf of the Issuers 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 October 1 of the years set forth below, as set forth below
(expressed as a percentage of the principal amount of the Notes on the date of
payment that would otherwise be due but for the provisions of this sentence):

        YEAR                                                          PERCENTAGE
        ----                                                          ----------
        1999.....................................................      109.750%
        2000.....................................................      108.775%
        2001.....................................................      107.800%
        2002.....................................................      106.825%
        2003.....................................................      105.850%



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
<PAGE>

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;

    (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
<PAGE>

dates, shall not be impaired or affected without the consent of such Holder.

Section 6.08.     Collection Suit by Trustee.

    If an Event of Default specified in Section 6.01(a) or (b) occurs and is
continuing, the Trustee is authorized to recover judgment in its own name and as
trustee of an express trust against the Issuers for the whole amount of
principal of, premium 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 Issuers
(or any other obligor upon the Notes), its creditors or its property and shall
be entitled and empowered to collect, receive and distribute any money or other
property payable or deliverable on any such claims and any custodian in any such
judicial proceeding is hereby authorized by each Holder to make such payments to
the Trustee, and in the event that the Trustee shall consent to the making of
such payments directly to the Holders, to pay to the Trustee any amount due to
it for the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel, and any other amounts due the Trustee under
Section 7.07 hereof. To the extent that the payment of any such compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel, and
any other amounts due the Trustee under Section 7.07 hereof out of the estate in
any such proceeding, shall be denied for any reason, payment of the same shall
be secured by a Lien on, and shall be paid out of, any and all distributions,
dividends, money, securities and other properties that the Holders may be
entitled to receive in such proceeding whether in liquidation or under any plan
of reorganization or arrangement or otherwise. Nothing herein contained shall be
deemed to authorize the Trustee to authorize or consent to or accept or adopt on
behalf of any Holder any plan of reorganization, arrangement, adjustment or
composition affecting the Notes or the rights of any Holder, or to authorize the
Trustee to vote in respect of the claim of any Holder in any such proceeding.

Section 6.10.     Priorities.

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

        First: to the Trustee, its agents and attorneys for amounts due under

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

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

Section 6.11.     Undertaking for Costs.

    In any suit for the enforcement of any right or remedy under this Indenture
or in any suit against the Trustee for any action taken or omitted by it as a
Trustee, a court in its discretion may require the filing by any party litigant
in the suit of an undertaking to pay the costs of the suit, and the court in its
discretion may assess reasonable costs, including reasonable attorneys' fees,
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.
                                    TRUSTEE

Section 7.01.     Duties of Trustee.

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

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

        (i) the duties of the Trustee shall be determined solely by the express

    implied covenants or obligations shall be read into this Indenture against
    the Trustee; and

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

    (c) The Trustee may not be relieved from liabilities for its own negligent
action, its own negligent failure to act, or its own willful misconduct, except
that:

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



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

    takes or omits to take in good faith in accordance with a direction received

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

security and indemnity satisfactory to it against any loss, liability or
<PAGE>

expense.

    (f) The Trustee shall not be liable for interest on any money received by it
except as the Trustee may agree in writing with the Issuers. Money held in trust

Officers' Certificate or an Opinion of Counsel or both. The Trustee shall not be
liable for any action it takes or omits to take in good faith in reliance on
such Officers' Certificate or Opinion of Counsel. The Trustee may consult with

reliance thereon.

request, direction or notice from the Issuers shall be sufficient if signed by
an Officer of an Issuer.

or powers vested in it by this Indenture at the request or direction of any of
the Holders unless such Holders shall have offered to the Trustee reasonable
security or indemnity against the costs, expenses and liabilities that might be
incurred by it in compliance with such request or direction.

Section 7.03.     Individual Rights of Trustee.

    The Trustee in its individual or any other capacity may become the owner or
pledgee of Notes and may otherwise deal with the Issuers or any Affiliate of the
Issuers with the same rights it would have if it were not Trustee. However, in
the event that the Trustee acquires any conflicting interest it must



eliminate such conflict within 90 days, apply to the SEC for permission to
continue as trustee or resign. Any Agent may do the same with like rights and
duties. The Trustee is also subject to Sections 7.10 and 7.11 hereof.

Section 7.04.     Trustee's Disclaimer.

    The Trustee shall not be responsible for and makes no representation as to
the validity or adequacy of this Indenture or the Notes, it shall not be
accountable for the Issuers' use of the proceeds from the Notes or any money
paid to the Issuers or upon the Issuers' direction under any provision of this
Indenture, it shall not be responsible for the use or application of any money
received by any Paying Agent other than the Trustee, and it shall not be
responsible for any statement or recital herein or any statement in the Notes or
any other document in connection with the sale of the Notes or pursuant to this
Indenture other than its certificate of authentication.
<PAGE>

Section 7.05.     Notice of Defaults.

    If a Default or Event of Default occurs and is continuing and if it is known
to the Trustee, the Trustee shall mail to Holders of Notes a notice of the
Default or Event of Default within 90 days after it occurs. Except in the case
of a Default or Event of Default in payment of principal of, premium, if any, or
interest 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 ss. 313(a) (but if no event described in TIA ss.
313(a) has occurred within the twelve months preceding the reporting date, no
report need be transmitted). The Trustee also shall comply with TIA ss.
313(b)(2). The Trustee shall also transmit by mail all reports as required by
TIA ss. 313(c).

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

Section 7.07.     Compensation and Indemnity.

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

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

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

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

Indenture.

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

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

Section 7.08.     Replacement of Trustee.

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

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

    (a) the Trustee fails to comply with Section 7.10 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 Issuers shall promptly appoint a successor Trustee.
Within one year after the successor Trustee takes office, the Holders of a
majority in principal amount of the then outstanding Notes may appoint a
successor Trustee to replace the successor Trustee appointed by the Issuers.

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



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

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

Section 7.09.     Successor Trustee by Merger, etc.
<PAGE>

    If the Trustee consolidates, merges or converts into, or transfers all or
substantially all of its corporate trust business to, another corporation, the
successor corporation without any further act shall be the successor Trustee.

Section 7.10.     Eligibility; Disqualification.

organized and doing business under the laws of the United States of America or
of any state thereof that is authorized under such laws to exercise corporate
trustee power, that is subject to supervision or examination by federal or state
authorities and that has, or is a direct or indirect wholly-owned subsidiary of
a bank holding company that has, a combined capital and surplus of at least $100
million as set forth in its most recent published annual report of condition.

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

Section 7.11.     Preferential Collection of Claims Against the Issuers.

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

                                   ARTICLE 8.
                    LEGAL DEFEASANCE AND COVENANT DEFEASANCE

Section 8.01.     Option to Effect Legal Defeasance or Covenant Defeasance.

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

Section 8.02.     Legal Defeasance and Discharge.

    Upon the Issuers' exercise under Section 8.01 hereof of the option
applicable to this Section 8.02, the Issuers shall, subject to the satisfaction
of the conditions set forth in Section 8.04 hereof, be deemed to have been
discharged from their obligations with respect to all outstanding Notes on the
date the



conditions set forth below are satisfied (hereinafter, "Legal Defeasance"). For
this purpose, Legal Defeasance means that the Issuers shall be deemed to have
paid and discharged the entire Indebtedness represented by the outstanding
Notes, which shall thereafter be deemed to be "outstanding" only for the
purposes of Section 8.05 hereof and the other Sections of this Indenture
referred to in (a) and (b) below, and to have satisfied all their other
obligations under such Notes and this Indenture (and the Trustee, on demand of
and at the expense of the Issuers, shall execute proper instruments
acknowledging the same), except for the following provisions which shall survive
until otherwise terminated or discharged hereunder: (a) the rights of Holders of
outstanding Notes to receive 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 Issuers' 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 Issuers'
obligations in connection therewith and (d) this Article Eight. Subject to
compliance with this Article Eight, the Issuers may exercise their option under
this Section 8.02 notwithstanding the prior exercise of its option under Section
8.03 hereof.
<PAGE>

Section 8.03.     Covenant Defeasance.

    Upon the Issuers' exercise under Section 8.01 hereof of the option
applicable to this Section 8.03, the Issuers shall, subject to the satisfaction
of the conditions set forth in Section 8.04 hereof, be released from their
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 Issuers may omit to comply with and shall have no
liability in respect of any term, condition or limitation set forth in any such
covenant, whether directly or indirectly, by reason of any reference elsewhere
herein to any such covenant or by reason of any reference in any such covenant
to any other provision herein or in any other document and such omission to
comply shall not constitute a Default or an Event of Default under Section 6.01
hereof, but, except as specified above, the remainder of this Indenture and such
Notes shall be unaffected thereby. In addition, upon the Issuers' exercise under
Section 8.01 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:

    (a) the Issuers 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 Issuers 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 Issuers shall
have delivered to the Trustee an Opinion of Counsel in the United States
reasonably acceptable to the Trustee confirming that (A) the Issuers have
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 Issuers shall
have delivered to the Trustee an Opinion of Counsel in the United States
reasonably acceptable to the Trustee confirming that the Holders of the
outstanding Notes will not recognize income, gain or loss for federal income tax
purposes as a result of such Covenant Defeasance and will be subject to federal
income tax on the same amounts, in the same manner and at the same times as
would have been the case if such Covenant Defeasance had not occurred;
<PAGE>

    (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 Issuers or any of their
Subsidiaries is a party or by which the Issuers or any of their Subsidiaries is
bound;

    (f) the Issuers shall have delivered to the Trustee an Opinion of Counsel to
the effect that, assuming no intervening bankruptcy of the Issuers between the
date of deposit and the 91st day following the deposit and assuming that no
Holder is an "insider" of the Issuers 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 Issuers shall deliver to the Trustee an Officers' Certificate
stating that the deposit was not made by the Issuers with the intent of
preferring the Holders over any other creditors of the Issuers or with the
intent of defeating, hindering, delaying or defrauding any other creditors of
the Issuers or others; and

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

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 either 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 Issuers shall pay and indemnify the Trustee against any tax, fee or
other charge imposed on or assessed against the cash or non-callable Government
Securities deposited pursuant to Section 8.04 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 Issuers from time to time upon the request of the
Issuers any money or non-callable Government Securities held by it as provided
in Section 8.04 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.
<PAGE>

Section 8.06.     Repayment to the Issuers.

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

Section 8.07.     Reinstatement.

    If the Trustee or Paying Agent is unable to apply any United States dollars
or non-callable Government Securities in accordance with Section 8.02 or 8.03
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 Issuers' obligations under this Indenture and the Notes
shall be revived and reinstated as though no deposit had occurred pursuant to
Section 8.02 or 8.03 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 Issuers make any
payment of principal of, premium, if any, or interest on any Note following the
reinstatement of their obligations, the Issuers shall be subrogated to the
rights of the Holders of such Notes to receive such payment from the money held
by the Trustee or Paying Agent.

                        AMENDMENT, SUPPLEMENT AND WAIVER

Section 9.01.     Without Consent of Holders of Notes.

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


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

    (b) to provide for uncertificated Notes in addition to or in place of
certificated Notes 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 Issuers' obligations to the Holders
of the Notes by a successor to the Issuers 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;

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

    (f) to provide for the issuance of Additional Notes in accordance with the
limitations set forth in this Indenture as of the date hereof.
<PAGE>

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

Section 9.02.     With Consent of Holders of Notes.

    Except as provided below in this Section 9.02, the Issuers 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 (including Additional Notes, if any) 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 (including Additional Notes, if any) voting as a
single class (including consents obtained in connection with a tender offer or
exchange offer for, or purchase of, the Notes). 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 Issuers accompanied by a resolution of their Boards
of Directors authorizing the execution of any such amended or supplemental
Indenture, and upon the filing with the Trustee of evidence satisfactory to the
Trustee of the consent of the Holders of Notes as aforesaid, and upon receipt by
the Trustee of the documents described in Section 7.02 hereof, the Trustee shall
join with the Issuers in the execution of such amended or supplemental Indenture
unless such amended or supplemental Indenture directly affects the Trustee's own
rights, duties or immunities under this Indenture or otherwise, in which case
the Trustee may in its discretion, but shall not be obligated to, enter into
such amended or supplemental Indenture.



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

    After an amendment, supplement or waiver under this Section becomes
effective, the Issuers shall mail to the Holders of Notes affected thereby a
notice briefly describing the amendment, supplement or waiver. Any failure of
the Issuers 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 (including Additional Notes,
if any) then outstanding voting as a single class may waive compliance in a
particular instance by the Issuers with any provision of this Indenture or the
Notes. However, without the consent of each Holder affected, an amendment or
waiver under this Section 9.02 may not (with respect to any Notes held by a
non-consenting Holder):

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

    (b) reduce the principal of or change the fixed maturity of any Note or
alter or waive any of the provisions with respect to the redemption of the Notes
<PAGE>

except as provided above with respect to Sections 3.09, 4.10 and 4.15 hereof;

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

    (d) waive a Default or Event of Default in the payment of 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 (including Additional
Notes, if any) and a waiver of the payment default that resulted from such
acceleration);

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

    (f) make any change in the provisions of this Indenture relating to waivers
of past Defaults or the rights of Holders of Notes to receive payments of
principal of or interest or 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 Issuers in exchange for all
Notes may issue and the Trustee shall, upon receipt of an Authentication Order,
authenticate new Notes that reflect the amendment, supplement or waiver.

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

Section 9.06.     Trustee to Sign Amendments, etc.

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

[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 Midwest, L.P., a Delaware limited partnership (the
"Company"), and Insight Capital, Inc., a Delaware corporation (together with the
Company, the "Issuers"), promise to pay interest on the principal amount of this
Note at 9 3/4% per annum from October 1, 1999 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. The Issuers will pay
interest and Liquidated Damages semi-annually in arrears on April 1 and October
1 of each year, or if any such day is not a Business Day, on the next succeeding
Business Day (each an "Interest Payment Date"). Interest on the Notes will
accrue from the most recent date to which interest has been paid or, if no
interest has been paid, from the date of issuance; provided that if there is no
existing Default in the payment of interest, and if this Note is authenticated
between a record date referred to on the face hereof and the next succeeding
Interest Payment Date, interest shall accrue from such next succeeding Interest
Payment Date; provided, further, that the first Interest Payment Date shall be
April 1, 2000. The Issuers shall pay interest (including post-petition interest
in any proceeding under any Bankruptcy Law) on overdue principal and premium, if
any, from time to time on demand at a rate that is 1% per annum in excess of the
rate then in effect; they shall pay interest (including post-petition interest
in any proceeding under any Bankruptcy Law) on overdue installments of interest
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 Issuers 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 March 15 or September 15 next
preceding the Interest Payment Date, even if such Notes are canceled after such
record date and on or before such Interest Payment Date, except as provided in
Section 2.12 of the Indenture with respect to defaulted interest. The Notes will
be payable as to principal, premium and Liquidated Damages, if any, and interest
at the office or agency of the Issuers maintained for such purpose within or
without the City and State of New York, or, at the option of the Issuers,
payment of interest 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 Issuers or the Paying Agent. Such payment
shall be in such coin or currency of the United States of America as at the time
of payment is legal tender for payment of public and private debts.

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

    4. INDENTURE. The Issuers issued the Notes under an Indenture dated as of
October 1, 1999 ("Indenture") among the Issuers and the Trustee. The terms of
the Notes include those stated in the
<PAGE>

Indenture and those made part of the Indenture by reference to the Trust
Indenture Act of 1939, as amended (15 U.S. Code ss.ss. 77aaa-77bbbb). The Notes
are subject to all such terms, and Holders are referred to the Indenture and
such Act for a statement of such terms. To the extent any provision of this Note
conflicts with the express provisions of the Indenture, the provisions of the
Indenture shall govern and be controlling. The Notes are obligations of the
Issuers limited to $400.0 million in aggregate principal amount.

    5. OPTIONAL REDEMPTION.

    (a) Except as set forth in subparagraph (b) of this Paragraph 5, the Issuers
shall not have the option to redeem the Notes prior to October 1, 2004.

applicable redemption date, if redeemed during the twelve-month period beginning

at any time prior to October 1, 2002, the Issuers may redeem Notes with the net
proceeds of one or more Equity Offerings at a redemption price equal to 109.75%
of the aggregate principal amount thereof; provided that at least 65% in
aggregate principal amount 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 Issuers shall not be required
to make mandatory redemption payments with respect to the Notes.

    7. REPURCHASE AT OPTION OF HOLDER.

    (a) If there is a Change of Control, the Issuers shall be required to make
an offer (a "Change of Control Offer") to repurchase all or any part (equal to
$1,000 or an integral multiple thereof) of each Holder's Notes at a purchase
price equal to 101% of the aggregate principal amount thereof plus accrued and
unpaid interest and Liquidated Damages thereon, if any, to the date of purchase
(the "Change of Control Payment"). Within 30 days following any Change of
Control, the Issuers 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 Issuers 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 Issuers 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 thereof plus accrued and unpaid
interest and Liquidated Damages thereon, if any, to the date fixed for the
closing of such offer in accordance with the procedures set forth in the
Indenture. To the extent
<PAGE>

that the aggregate amount of Notes (including any Additional Notes) tendered
pursuant to an Asset Sale Offer is less than the Excess Proceeds, the Issuers
(or such Restricted Subsidiary) may use such deficiency for any purpose not
otherwise prohibited by the Indenture. If the aggregate principal amount 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 Issuers 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
Issuers may require a Holder to pay any taxes and fees required by law or
permitted by the Indenture. The Issuers need not exchange or register the
transfer of any Note or portion of a Note selected for redemption, except for
the unredeemed portion of any Note being redeemed in part. Also, the Issuers
need not exchange or register the transfer of any Notes for a period of 15 days
before a selection of Notes to be redeemed or during the period between a record
date and the corresponding Interest Payment Date.

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

    11. AMENDMENT, SUPPLEMENT AND WAIVER. Subject to certain exceptions, the
Indenture or the Notes may be amended or supplemented with the consent of the
Holders of at least a majority in principal amount of the then outstanding Notes
and Additional Notes, if any, 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 and Additional Notes, if any, 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 Issuers' 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, to comply with the requirements of the SEC in order to effect or
maintain the qualification of the Indenture under the Trust Indenture Act and to
provide for the issuance of Additional Notes in accordance with the limitations
set forth in the Indenture.

    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 Company to comply with Sections 3.09, 4.10, 4.15 or 5.01 of the
Indenture; (iv) failure by the Issuers for 30 days after notice to the Issuers
by the Trustee or to the Issuers and the Trustee by the Holders of at least 25%
in principal amount of the Notes (including Additional Notes, if any) then
<PAGE>

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 Issuers or their 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 Issuers or any of their 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 Issuers are required to deliver to the Trustee
annually a statement regarding compliance with the Indenture, and the Issuers
are required upon becoming aware of any Default or Event of Default, to deliver
to the Trustee a statement specifying such Default or Event of Default.

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

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

    15. 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 October 1, 1999 among the Issuers and the parties named on the
signature pages thereof or, in the case of Additional Notes, Holders of
Restricted Global Notes and Restricted Definitive Notes shall have the rights
set forth in one or more registration rights agreements, if any, between the
Company and the other parties thereto, relating to rights given by the Company
to the purchasers of any Additional Notes (collectively, the "Registration
Rights Agreement").

    18. CUSIP NUMBERS. Pursuant to a recommendation promulgated by the Committee
<PAGE>

on Uniform Security Identification Procedures, the Issuers have caused CUSIP
numbers to be printed on the Notes and the Trustee may use CUSIP numbers in
notices of redemption as a convenience to Holders. No representation is made as
to the accuracy of such numbers either as printed on the Notes or as contained



in any notice of redemption and reliance may be placed only on the other
identification numbers placed thereon.

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

the most recent date to which interest has been paid or, if no interest has been
paid, from the date of issuance; provided that if there is no existing Default
in the payment of interest, and if this Note is authenticated between a record
date referred to on the face hereof and the next succeeding Interest Payment
Date, interest shall accrue from such next succeeding Interest Payment Date;
provided, further, that the first Interest Payment Date shall be April 1, 2000.
The Issuers shall pay interest (including post-petition interest in any
proceeding under any Bankruptcy Law) on overdue principal and premium, if any,

proceeding under any Bankruptcy Law) on overdue installments of interest and
Liquidated Damages (without regard to any applicable grace periods) from time to

benefits as other Senior Notes under the Indenture.

defaulted interest) and Liquidated Damages to the Persons who are registered

are referred to the Indenture and such Act for a statement of such terms. To the
extent any provision of this

the Indenture shall govern and be controlling. The Notes are obligations of the
Issuers limited to $400.0 million in aggregate principal amount.

in part, upon not less than 30 nor more than 60 days' notice, at the redemption

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

at any time prior to October 1, 2002, the Issuers may redeem Notes with the net
proceeds of one or more Equity Offerings at a redemption price equal to 109.75%
of the aggregate principal amount thereof; provided that at least 65% in
aggregate principal amount any of the Notes issued under the Indenture remain
outstanding immediately after the occurrence of any such redemption and that

Equity Offering.

    5. MANDATORY REDEMPTION.

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

    (a) If there is a Change of Control, the Issuers shall be required to make
an offer (a "Change of Control Offer") to repurchase all or any part (equal to
$1,000 or an integral multiple thereof) of each Holder's Notes at a purchase
price equal to 101% of the aggregate principal amount thereof plus accrued and
unpaid interest, if any, to the date of purchase the "Change of Control
Payment"). Within 30 days following any Change of Control, the Issuers 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 Issuers 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 Issuers shall commence an offer to all Holders of
<PAGE>

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 thereof plus accrued and unpaid
interest and Liquidated Damages, if any, to the date fixed for the closing of
such offer in accordance with the procedures set forth in the Indenture. To the
extent that the aggregate amount of Notes tendered pursuant to an Asset Sale
Offer is less than the Excess Proceeds, the Issuers (or such Restricted
Subsidiary) may use such deficiency for any purpose not otherwise prohibited by
the Indenture. If the aggregate principal amount 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 Issuers prior to any related purchase date and may elect to have

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, 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. 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

qualification of the Indenture under the Trust Indenture Act.

    11. DEFAULTS AND REMEDIES. Events of Default include: (i) default for 30

by the Issuers to comply with Sections 3.09, 4.10, 4.15 or 5.01 of the

in principal amount of the Notes then outstanding to comply with certain other
agreements in the Indenture or the Notes; (v) default under certain other
agreements relating to Indebtedness of the Issuers or their



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 Issuers or any of
their 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 principal, premuim, interest or Liquidated Damages on the Notes. The
Issuers are, required to deliver to the Trustee annually a statement regarding
compliance with the Indenture, and the Issuers are, 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.

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

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

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

    15. ABBREVIATIONS. Customary abbreviations may be used in the name of a

on Uniform Security Identification Procedures, the Issuers have caused CUSIP

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

         3. We understand that, on any proposed resale of the Notes or
beneficial interest therein, we will be required to furnish to you and the
Company such certifications, legal opinions and other information as you and the
Company may reasonably require to confirm that the proposed sale complies with
the foregoing restrictions. We further understand that the Notes purchased by us
will bear a legend to the foregoing effect.

         4. We are an institutional "accredited investor" (as defined in Rule
501(a)(1), (2), (3) or (7) of Regulation D under the Securities Act) and have
such knowledge and experience in financial and business matters as to be capable
of evaluating the merits and risks of our investment in the Notes, and we and
any accounts for which we are acting are each able to bear the economic risk of
our or its investment.

         5. We are acquiring the Notes or beneficial interest therein purchased
by us for our own account or for one or more accounts (each of which is an

irrevocably authorized to produce this letter or a copy hereof to any interested
party in any administrative or legal proceedings or official inquiry with
respect to the matters covered hereby.
