                                    THE NOTES

SECTION 2.01.  FORM AND DATING.

           The Notes and the Trustee's certificate of authentication shall be
substantially in the form of Exhibit A hereto. The Notes may have notations,
legends or endorsements required by law, stock exchange rule or usage. Each Note
shall be dated the date of its authentication. The Notes shall be issued in
minimum denominations of $1,000 and integral multiples thereof.

           The terms and provisions contained in the Notes shall constitute, and
are hereby expressly made, a part of this Indenture and the Issuers and the
Trustee, by their execution and delivery of this Indenture, expressly agree to
such terms and provisions and to be bound thereby.

           Notes issued in global form shall be substantially in the form of
Exhibit A attached hereto (including the text referred to in footnotes 1 and 2
thereto). Notes issued in definitive form shall be substantially in the form of
Exhibit A attached hereto (but without including the text referred to in
footnotes 1 and 2 thereto). Each Global Note shall represent such of the
outstanding Notes as shall be specified therein and each shall provide that it
shall represent the aggregate amount of outstanding Notes from time to time
endorsed thereon and that the aggregate amount of outstanding Notes represented
thereby may from time to time be reduced or increased, as appropriate, to
reflect exchanges and redemptions. Any endorsement of a Global Note to reflect
the amount of any increase or decrease in the amount of outstanding Notes
represented thereby shall be made by the Trustee or the Note Custodian, at the
direction of the Trustee, in accordance with instructions given by the Holder
thereof as required by Section 2.06 hereof.

SECTION 2.02.   EXECUTION AND AUTHENTICATION.

           The General Partner of ICP-IV and an Officer of IPCC shall sign the
Notes for ICP-IV or IPCC, as applicable, by manual or facsimile signature.

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


                                       22
   31
           A Note shall not be valid until authenticated by the manual signature
of the Trustee. The signature shall be conclusive evidence that the Note has
been authenticated under this Indenture.

           The Trustee shall, upon a written order of the Issuers signed by the
General Partner of ICP-IV and an Officer of IPCC, authenticate Notes for
original issue up to the aggregate principal amount stated in paragraph 4 of the
Notes. The aggregate principal amount of Notes outstanding at any time may not
exceed such amount except as provided in Section 2.07 hereof.

           The Trustee may appoint an authenticating agent acceptable to the
Issuers to authenticate Notes. An authenticating agent may authenticate Notes
whenever the Trustee may do so. Each reference in this Indenture to
authentication by the Trustee includes authentication by such agent. An
authenticating agent has the same rights as an Agent to deal with the Issuers or
an Affiliate of the Issuers.

SECTION 2.03.   REGISTRAR AND PAYING AGENT.

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

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

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

SECTION 2.04.   PAYING AGENT TO HOLD MONEY IN TRUST.

           The Issuers shall require each Paying Agent other than the Trustee to
agree in writing that the Paying Agent will hold in trust for the benefit of
Holders or the Trustee all money held by the Paying Agent for the payment of
principal, premium or Liquidated Damages, if any, or interest on the Notes, and
will notify the Trustee of any default by the Issuers in making any such


                                       23
   32
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 ICP-IV or a Subsidiary
thereof) shall have no further liability for the money. If ICP-IV or a
Subsidiary thereof 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
either of the Issuers, the Trustee shall serve as Paying Agent for the Notes.

SECTION 2.05.   HOLDER LISTS.

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

SECTION 2.06.   TRANSFER AND EXCHANGE.

           (a) Transfer and Exchange of Definitive Notes. When Definitive Notes
are presented by a Holder to the Registrar with a request:

                (x)   to register the transfer of the Definitive Notes; or

                (y)   to exchange such Definitive Notes for an equal principal
                      amount of Definitive Notes of other authorized
                      denominations,

the Registrar shall register the transfer or make the exchange as requested if
its requirements for such transactions are met; provided, however, that the
Definitive Notes presented or surrendered for register of transfer or exchange:

                      (i)  shall be duly endorsed or accompanied by a written
                           instruction of transfer in form satisfactory to the
                           Registrar duly executed by such Holder or by his
                           attorney, duly authorized in writing; and

                      (ii) in the case of a Definitive Note that is a Transfer
                           Restricted Security, such request shall be
                           accompanied by the following additional information
                           and documents, as applicable:

                                delivered to the Registrar by a Holder for
                                registration in the name of such Holder, without
                                transfer, a certification to that effect from
                                such Holder (in substantially the form of
                                Exhibit B hereto); or

                           (B)  if such Transfer Restricted Security is being
                                transferred to a "qualified institutional buyer"
                                (as defined in Rule 144A under the Securities
                                Act) in accordance with Rule 144A under the
                                Securities Act or pursuant to an exemption from
                                registration in accordance with Rule 144 or Rule
                                904 under the Securities Act or pursuant to an
                                effective registration statement under the
                                Securities Act, a certification to that effect
                                from such Holder (in substantially the form of
                                Exhibit B hereto); or

                           (C)  if such Transfer Restricted Security is being
                                transferred in reliance on another exemption
                                from the registration requirements of the
                                Securities Act, a certification to that effect
                                from such Holder (in substantially the form of
                                Exhibit B hereto) and an Opinion of Counsel from
                                such Holder or the transferee reasonably
                                acceptable to the Issuers and to the Registrar
                                to the effect that such transfer is in
                                compliance with the Securities Act.

           (b) Transfer of a Definitive Note for a Beneficial Interest in a
Global Note. A Definitive Note may not be exchanged for a beneficial interest in
a Global Note except upon satisfaction of the requirements set forth below. Upon
receipt by the Trustee of a Definitive Note, duly endorsed or accompanied by
appropriate instruments of transfer, in form satisfactory to the Trustee,
together with:

           (i)  if such Definitive Note is a Transfer Restricted Security, a
                certification from the Holder thereof (in substantially the form
                of Exhibit B hereto) to the effect that such Definitive Note is
                being transferred by such Holder to a "qualified institutional
                buyer" (as defined in Rule 144A under the Securities Act) in
                accordance with Rule 144A under the Securities Act; and

                endorsement on the Global Note to reflect an increase in the
                aggregate principal amount of the Notes represented by the
                Global Note,

in which case the Trustee shall cancel such Definitive Note in accordance with
Section 2.11 hereof and cause, or direct the Note Custodian to cause, in
accordance with the standing instructions and procedures existing between the
Depository and the Note Custodian, the aggregate principal amount of Notes

are then outstanding, the Issuers shall issue and, upon receipt of an
authentication order in accordance with Section 2.02 hereof, the Trustee shall
authenticate, a new Global Note in the appropriate principal amount.

           (c) Transfer and Exchange of Global Notes. The transfer and exchange

                                registration requirements of the Securities Act,
                                a certification to that effect from the
                                transferor (in substantially the form of Exhibit

                                the Securities Act,

                      direction of the Trustee, shall, in accordance with the
                      standing instructions and procedures existing between the

                      principal amount of Global Notes to be reduced accordingly
                      and, following such reduction, the Issuers shall execute
                      and, upon receipt of an authentication order in accordance
                      with Section 2.02 hereof, the Trustee shall authenticate
                      and deliver to the transferee a Definitive Note in the
                      appropriate principal amount.

                (ii)  Definitive Notes issued in exchange for a beneficial
                      interest in a Global Note pursuant to this Section 2.06(d)
                      shall be registered in such names and in such authorized
                      denominations as the Depository, pursuant to instructions
                      from its direct or indirect participants or otherwise,
                      shall instruct the Trustee. The Trustee shall deliver such
                      Definitive Notes to the Persons in whose names such Notes
                      are so registered.

           (e) Restrictions on Transfer and Exchange of Global Notes.
Notwithstanding any other provision of this Indenture (other than the provisions
set forth in subsection (f) of this Section 2.06), a Global Note may not be
transferred as a whole except by the Depository to a nominee of the Depository
or by a nominee of the Depository to the Depository or another nominee of the
Depository or by the Depository or any such nominee to a successor Depository or
a nominee of such successor Depository.

                      Depository is unwilling or unable to continue as
                      Depository for the Global Notes and a successor Depository
                      for the Global Notes is not appointed by the Issuers
                      within 90 days after delivery of such notice; or


                                       27
   36
                (ii)  the Issuers, at their discretion, notify the Trustee in
                      writing that they elect to cause the issuance of
                      Definitive Notes under this Indenture,

then the Issuers shall execute, and the Trustee shall, upon receipt of an
authentication order in accordance with Section 2.02 hereof, authenticate and
deliver, Definitive Notes in an aggregate principal amount equal to the
principal amount of the Global Notes in exchange for such Global Notes.

           (g) Legends.

                (i)   Except as permitted by the following paragraphs (ii) and

                      THE NOTE EVIDENCED HEREBY OF THE RESALE RESTRICTIONS SET
                      FORTH IN (A) ABOVE."

   37
                (ii)  Upon any sale or transfer of a Transfer Restricted
                      Security (including any Transfer Restricted Security
                      represented by a Global Note) pursuant to Rule 144 under
                      the Securities Act or pursuant to an effective
                      registration statement under the Securities Act:

                      (A)  in the case of any Transfer Restricted Security that
                           is a Definitive Note, the Registrar shall permit the
                           Holder thereof to exchange such Transfer Restricted
                           Security for a Definitive Note that does not bear the
                           legend set forth in (i) above and rescind any
                           restriction on the transfer of such Transfer
                           Restricted Security; and

                      (B)  in the case of any Transfer Restricted Security
                           represented by a Global Note, such Transfer
                           Restricted Security shall not be required to bear the
                           legend set forth in (i) above, but shall continue to
                           be subject to the provisions of Section 2.06(c)
                           hereof; provided, however, that with respect to any
                           request for an exchange of a Transfer Restricted
                           Security that is represented by a Global Note for a
                           Definitive Note that does not bear the legend set
                           forth in (i) above, which request is made in reliance
                           upon Rule 144, the Holder thereof shall certify in
                           writing to the Registrar that such request is being
                           made pursuant to Rule 144 (such certification to be
                           substantially in the form of Exhibit B hereto).

                (iii) Notwithstanding the foregoing, upon consummation of the
                      Exchange Offer, the Issuers shall issue and, upon receipt
                      of an authentication order in accordance with Section 2.02
                      hereof, the Trustee shall authenticate New Notes in
                      exchange for Original Notes accepted for exchange in the
                      Exchange Offer, which New Notes shall not bear the legend
                      set forth in (i) above, and the Registrar shall rescind
                      any restriction on the transfer of such Notes, in each
                      case unless the Holder of such Original Notes is either
                      (A) a broker-dealer, (B) a Person participating in the
                      distribution of the Original Notes or (C) a Person who is
                      an affiliate (as defined in Rule 144A) of the Issuers.

           (h) Cancellation and/or Adjustment of Global Notes. At such time as
all beneficial interests in Global Notes have been exchanged for Definitive
Notes, redeemed, repurchased or cancelled, all Global Notes shall be returned to
or retained and cancelled 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 Definitive Notes, redeemed, repurchased or cancelled, the
principal amount of Notes represented by such Global


                                       29
   38
Note shall be reduced accordingly and an endorsement shall be made on such
Global Note, by the Trustee or the Note Custodian, at the direction of the
Trustee, to reflect such reduction.

           (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 Definitive Notes and Global Notes at the
                           Registrar's request.

                      (ii) No service charge shall be made to a Holder 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 3.07, 4.10,
                           4.15 and 9.05 hereto).

                    (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 Definitive Notes and Global Notes issued upon any
                           registration of transfer or exchange of Definitive
                           Notes or Global Notes shall be the valid obligations
                           of the Issuers, evidencing the same debt, and
                           entitled to the same benefits under this Indenture,
                           as the Definitive Notes or Global 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 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; or

                           (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.


                                       30
   39
                      (vi) Prior to due presentment for the registration of a
                           transfer of any Note, the Trustee, any Agent and the
                           Issuers may deem and treat the Person in whose name
                           any Note is registered as the absolute owner of such
                           Note for the purpose of receiving payment of
                           principal of and interest on such Notes, and neither
                           the Trustee, any Agent nor the Issuers shall be
                           affected by notice to the contrary.

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

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 the written
order of the Issuers signed by two Officers of each Issuer, 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 cancelled 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 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 either
of the Issuers holds the Note.

           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 bona fide 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.


                                       31
   40
           If the Paying Agent (other than ICP-IV, 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 Affiliate of either Issuer, shall be considered as though not
outstanding, except that for the purposes of determining whether the Trustee
shall be protected in relying on any such direction, waiver or consent, only
Notes that the Trustee actually knows are so owned shall be so disregarded.

SECTION 2.10.   TEMPORARY NOTES.

           Until definitive Notes are ready for delivery, the Issuers may
prepare and the Trustee shall authenticate temporary Notes upon a written order
of the Issuers signed by two Officers of each of the Issuers. Temporary Notes
shall be substantially in the form of definitive 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.

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 retain
canncelled Notes or return them to the Issuers at the written request of 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 ICP-IV defaults in a payment of interest on the Notes, it shall
pay the defaulted interest in any lawful manner plus, to the extent lawful,
interest payable on the defaulted interest, to the Persons who are Holders on a
subsequent special record date, in each case at the rate provided in the Notes
and in Section 4.01 hereof. ICP-IV shall notify the Trustee in writing of the
amount of defaulted interest proposed to be paid on each Note and the date


                                       32
   41
of the proposed payment. ICP-IV 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, ICP-IV (or, upon the written
request of ICP-IV, the Trustee in the name and at the expense of ICP-IV) shall
mail or cause to be mailed to Holders a notice that states the special record
date, the related payment date and the amount of such interest to be paid.

SECTION 2.13.   CUSIP NUMBERS.

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


                                    ARTICLE 3
                            REDEMPTION AND PREPAYMENT

SECTION 3.01.   NOTICES TO TRUSTEE.

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

SECTION 3.02.   SELECTION OF NOTES TO BE REDEEMED.

           If less than all of the Notes are to be redeemed at any time, the
Trustee shall select the Notes to be redeemed 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; provided that no Notes of $1,000 or less will be
redeemed in part. In the event that less than all of the Notes are to be
redeemed 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.


                                       33
   42
           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,
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. Failure to receive
such notice or any defect in the notice to any such Holder shall not affect the
validity of the proceedings for the redemption of any other Notes or portion
thereof.

           The notice shall identify the Notes to be redeemed (including CUSIP
number) 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 ICP-IV defaults in making such redemption payment,
      interest on Notes called for redemption ceases to accrue on and after the
      redemption date;

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

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


                                       34
   43
           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 (unless the
Trustee and the Issuers agree to a shorter period) 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, ICP-IV shall deposit
with the Trustee or with the Paying Agent money sufficient to pay the redemption
price of and accrued interest and Liquidated Damages, if any, on all Notes to be
redeemed on that date. The Trustee or the Paying Agent shall promptly return to
ICP-IV any money deposited with the Trustee or the Paying Agent by ICP-IV in
excess of the amounts necessary to pay the redemption price of, and accrued
interest on, all Notes to be redeemed.

           If ICP-IV complies with the provisions of the preceding paragraph, on
and after the redemption date, interest shall cease to accrue on the Notes or
the portions of Notes called for redemption. If a Note is redeemed on or after
an interest record date but on or prior to the related interest payment date,
then any accrued and unpaid interest and Liquidated Damages, if any, 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 ICP-IV 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 Note 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.


                                       35

                  ____                                                                  __________

                                                                                           
                  2001 .................................................................      105.625%
                  2002 .................................................................      103.750%
                  2003 .................................................................      101.875%
                  2004 and thereafter...................................................      100.000%


           (b) Notwithstanding the provisions of clause (a) of this Section 
3.07, at any time prior to August 1, 1999, ICP-IV may redeem up to 35.0% of the
aggregate principal amount of Notes originally issued with the net proceeds of a
Public Equity Offering or a Strategic Equity Investment at a redemption price
equal to 111.25% of the principal amount thereof, plus accrued and unpaid
interest and Liquidated Damages, if any, to the date of redemption; provided,
however, that at least 65.0% in aggregate principal amount of the Notes
originally issued remains outstanding immediately after the occurrence of such
redemption and, provided further, that such redemption occurs within 90 days
after the date of the closing of such Public Equity Offering or a Strategic
Equity Investment.

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

SECTION 3.08.   MANDATORY REDEMPTION.

           Except as set forth under Sections 4.10 and 4.15 hereof, the Issuers
shall not be required to make mandatory redemption payments or sinking fund
payments with respect to the Notes.

SECTION 3.09.   OFFER TO PURCHASE BY APPLICATION OF EXCESS PROCEEDS.

           In the event that, pursuant to Section 4.10 hereof, ICP-IV shall be
required to commence an offer to all Holders to purchase Notes (an "Asset Sale
Offer"), it shall follow the procedures specified below.


                                       36
   45
           The Asset Sale Offer shall be made to all Holders and 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").

           If the Asset Sale Offer Purchase Date is on or after an interest
record date and on or before the related interest payment date, any accrued and
unpaid interest and Liquidated Damages thereon, if any, 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.

           Within 10 days following any Asset Sale Offer Trigger Date, ICP-IV
shall send, by first class mail, a notice to each of the Holders at such
Holder's registered address, with a copy to the Trustee. The notice, which shall
govern the terms of the Asset Sale Offer, shall contain all instructions and
materials necessary to enable such Holders to tender Notes pursuant to the Asset
Sale Offer, and shall state:

                (a) that the Asset Sale Offer Trigger Date has occurred pursuant
      to Section 4.10 hereof and that ICP-IV is offering to purchase the maximum
      principal of Notes that may be purchased out of the Excess Proceeds (the
      "Offer Amount") at an offer price in cash in an amount equal to 100.0% of
      the principal amount thereof, plus accrued and unpaid interest and
      Liquidated Damages thereon, if any, to date of purchase, which shall be a
      Business Day (the "Asset Sale Offer Purchase Date") that is not earlier
      than 30 days nor later than 60 days from the date such notice is mailed;

                (b) the amount of accrued and unpaid interest, if any, and
      unpaid Liquidated Damages, if any, as of the Asset Sale Offer Purchase
      Date;

                (c) that any Note subject to the Asset Sale Offer not tendered
      shall continue to accrue interest;

                (d) that, unless ICP-IV defaults in the payment of the purchase
      price for the Notes payable pursuant to the Asset Sale Offer, any such
      Notes accepted for payment pursuant to the Asset Sale Offer shall cease to
      accrue interest, after the Asset Sale Offer Purchase Date;

                (e) that Holders electing to have a Note purchased pursuant to
      an Asset Sale Offer may only elect to have all of such Note purchased and
      may not elect to have only a portion of such Note purchased;

                (f) that Holders electing to have a Note purchased pursuant to
      any Asset Sale Offer shall be required to surrender


                                       37
   46
      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
      ICP-IV, a depositary, if appointed by ICP-IV, 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
      ICP-IV, 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 or less than all of the Notes tendered
      pursuant to the Asset Sale Offer are accepted for payment by ICP-IV for
      any reason consistent with this Indenture, the Trustee shall select the
      Notes to be purchased 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 by such method
      as the Trustee deems fair and appropriate; provided that Notes accepted
      for payment in part will only be purchased in integral multiples of
      $1,000; 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 the Asset Sale Offer Purchase Date, ICP-IV shall: (i) accept for
payment the maximum principal amount of Notes or portions thereof tendered
pursuant to the Asset Sale Offer that can be purchased out of the Excess
Proceeds; (ii) deposit with the Paying Agent the aggregate purchase price of all
Notes or portions thereof accepted for payment; and (iii) deliver or cause to be
delivered to the Trustee all Notes tendered pursuant to the Asset Sale Offer.
ICP-IV, the depository or the Paying Agent, as the case may be, shall promptly
mail to each Holder of Notes or portions thereof accepted for payment an amount
equal to the purchase price for such Notes and the Trustee shall promptly
authenticate and mail to any such Holder of Notes accepted for payment in part a
new Note equal in principal amount to any unpurchased portion of the Notes, and
any Note not accepted for payment in whole or in part shall be promptly returned
to the Holder of such Note. ICP-IV shall announce the results of the Asset Sale
Offer to Holders of the Notes on or as soon as practicable after the Asset Sale
Offer Purchase Date. The Issuers shall comply, to the extent applicable, with
the requirements of Section 14(e) of the Exchange Act, and any other securities
laws or regulations, in connection with any Asset Sale Offer.


                                       38
   47
           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.

                                    COVENANTS

SECTION 4.01.   PAYMENT OF NOTES.

           ICP-IV 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 ICP-IV or a Subsidiary thereof,
holds as of 10:00 a.m. Eastern Time on the due date money deposited by ICP-IV in
immediately available funds and designated for and sufficient to pay all
principal, premium, if any, and interest then due. ICP- IV 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.

           ICP-IV shall pay interest (including post-petition interest in any
proceeding under any Bankruptcy Law) on overdue principal at the rate equal to
1.0% per annum in excess of the then applicable interest rate on the Notes to
the extent lawful; it 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


                                       39
   48
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.

SECTION 4.03.   REPORTS.

           (a) Whether or not required by the rules and regulations of the SEC,
so long as any Notes are outstanding, ICP-IV shall furnish to the Trustee and to
all 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 ICP-IV were required to file such forms, including a "Management's
Discussion and Analysis of Financial Condition and Results of Operations" that
describes the financial condition and results of operations of ICP-IV and its
Restricted Subsidiaries and, with respect to the annual information only, a
report thereon by ICP-IV's certified independent accountants; and (ii) all
reports that would be required to be filed with the SEC on Form 8-K if ICP-IV
were required to file such reports. In addition, whether or not required by the
rules and regulations of the SEC, ICP-IV shall file a copy of all such
information and reports with the SEC for public availability (unless the SEC
will not accept such a filing) and shall promptly make such information
available to all securities analysts and prospective investors upon request.
ICP-IV shall at all times comply with TIA Section 314(a).

           (b) For so long as any Transfer Restricted Securities remain
outstanding, ICP-IV shall furnish to all Holders and prospective purchasers of
the Notes designated by the Holders of Transfer Restricted Securities, promptly
upon their request, the information required to be delivered pursuant to Rule
144A(d)(4) under the Securities Act.

           (c) Delivery of such reports, information and documents to the
Trustee is for informational purposes only and the Trustee's receipt of such
shall not constitute constructive notice of any information contained therein or
determinable from information contained therein, including the Issuers'
compliance with any of the covenants hereunder (as to which the Trustee is
entitled to rely exclusively on Officers' Certificates).

SECTION 4.04.   COMPLIANCE CERTIFICATE.

           (a) Each of 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 IPCC and


                                       40
   49
ICP-IV and its Subsidiaries during the preceding fiscal year has been made under
the supervision of the signing Officers with a view to determining whether such
Issuer has kept, observed, performed and fulfilled its obligations under this
Indenture and the Pledge Agreement, and further stating, as to each such Officer
signing such certificate, that to the best of his or her knowledge such Issuer
has kept, observed, performed and fulfilled each and every covenant contained in
this Indenture and the Pledge Agreement and is not in default in the performance
or observance of any of the terms, provisions and conditions of this Indenture
and the Pledge Agreement (or, if a Default or Event of Default shall have
occurred and is continuing, describing all such Defaults or Events of Default of
which he or she may have knowledge and what action ICP-IV is taking or proposes
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 ICP-IV is
taking or proposes to take with respect thereto.

           (b) So long as not contrary to the then current recommendations of
the American Institute of Certified Public Accountants, the year-end financial
statements delivered pursuant to Section 4.03(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 ICP-IV is taking or proposes to take with respect
thereto.

SECTION 4.05.   TAXES.

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

SECTION 4.06.   STAY, EXTENSION AND USURY LAWS.


                                       41
   50
           ICP-IV covenants (to the extent that it may lawfully do so) that it
shall not at any time insist upon, plead, or in any manner whatsoever claim or
take the 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 ICP-IV (to the extent that it may
lawfully do so) hereby expressly waives all benefit or advantage of any such
law, and covenants that it shall not, by resort to any such law, hinder, delay
or impede the execution of any power herein granted to the Trustee, but shall
suffer and permit the execution of every such power as though no such law has
been enacted.

SECTION 4.07.   RESTRICTED PAYMENTS.

           ICP-IV shall not, and shall not permit any of its Restricted
Subsidiaries to, directly or indirectly: (i) declare or pay any dividend or make
any other payment or distribution on account of the Equity Interests of ICP-IV
or any of its Restricted Subsidiaries (including, without limitation, any
payment in connection with any merger or consolidation) or to the direct or
indirect holders of the Equity Interests of ICP-IV or any of its Restricted
Subsidiaries in their capacity as such, other than dividends or distributions of
Equity Interests (other than Disqualified Stock) of ICP-IV or dividends or
distributions payable to ICP-IV or any Restricted Subsidiary of ICP-IV; (ii)
purchase, redeem or otherwise acquire or retire for value any Equity Interests
of ICP-IV or any Affiliate of ICP-IV; (iii) make any principal payment on, or
purchase, redeem, defease or otherwise acquire or retire for value any
Indebtedness that is subordinated to the Notes, except at final maturity; (iv)
make any Restricted Investment or (v) designate any Restricted Subsidiary to be
an Unrestricted Subsidiary (all such payments and other actions set forth in
clauses (i) through (v) 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 or would occur as a consequence thereof; and

           (b) the aggregate amount of such Restricted Payment and all other
      Restricted Payments declared or made after the Issue Date (excluding those
      permitted by clauses (x), (y) and (z) of the following paragraph) would
      exceed, at the date of determination, an amount equal to the sum of (1)
      the excess of (A) Cumulative EBITDA from the Issue Date to the end of
      ICP-IV's most recently ended full fiscal quarter for which consolidated
      financial statements are available, taken as a single accounting period,
      over (B) the product of 1.2 times ICP-IV's Cumulative Interest Expense
      from the Issue Date to the end of ICP-IV's most recently ended full fiscal
      quarter for which consolidated financial statements are available, taken
      as a single accounting period,


                                       42
   51
      plus (2) Capital Stock Proceeds, plus (3) to the extent that any
      Restricted Investment that was made after the Issue Date 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) $10.0 million; and

           (c) ICP-IV would, immediately after giving effect to such Restricted
      Payment as if the same had occurred at the beginning of the most recently
      ended full fiscal quarter of ICP-IV for which consolidated financial
      statements are available, have been permitted to incur at least $1.00 of
      additional Indebtedness (other than Permitted Debt) pursuant to Section 
      4.09 hereof.

      Provided that no Event of Default shall have occurred and be continuing,
the foregoing provisions shall not prohibit: (t) the D.D. Cable Transactions;
(u) distribution of the proceeds from the sale of the AVR Interests up to $5.0
million; (v) quarterly distributions in respect of partners' income tax
liability in an amount not to exceed the Tax Amount; (w) the payment of any
dividend or distribution 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; (x) the payment of in-kind dividends on the RMH
Redeemable Preferred Stock in accordance with the terms thereof as in effect on
the Issue Date; (y) the redemption, repurchase, retirement or other acquisition
of any Equity Interests of ICP-IV in exchange for, or out of the proceeds of,
the substantially concurrent sale (other than to a Subsidiary of ICP-IV) of
other Equity Interests of ICP-IV (other than any Disqualified Stock), provided
that the amount of any such net cash proceeds that are utilized for any such
redemption, repurchase, retirement or other acquisition shall be excluded from
clause (b)(2) of the preceding paragraph; and (z) the defeasance, redemption or
repurchase of subordinated Indebtedness with the net cash proceeds from an
incurrence of Permitted Refinancing Debt or the substantially concurrent sale
(other than to a Subsidiary of ICP-IV) of Equity Interests of ICP- IV (other
than Disqualified Stock), provided that the amount of any such net cash proceeds
from sales of Equity Interests that are utilized for any such redemption,
repurchase, retirement or other acquisition shall be excluded from clause (b)(2)
of the preceding paragraph.

      The amount of all Restricted Payments (other than cash) shall be the fair
market value (evidenced by a resolution of the Board of Directors set forth in
an Officers' Certificate delivered to the Trustee) on the date of the Restricted
Payment of the asset(s) proposed to be transferred by ICP-IV or such Restricted
Subsidiary, as the case may be, pursuant to the Restricted Payment. Not later
than the date of making any Restricted Payment, ICP-IV will deliver to the
Trustee an Officers' Certificate stating that such Restricted Payment is
permitted and setting forth the basis upon


                                       43
   52
which the calculations required by the first paragraph of this Section 4.07 were
computed, which calculations may be based upon ICP-IV's most recently available
financial statements.

SECTION 4.08.   DIVIDEND AND OTHER PAYMENT RESTRICTIONS AFFECTING SUBSIDIARIES.

           ICP-IV shall not, and shall not permit any of its Restricted
Subsidiaries to, directly or indirectly, create or otherwise cause or suffer to
exist or become effective any encumbrance or restriction on the ability of any
Restricted Subsidiary to: (i)(a) pay dividends or make any other distributions
to ICP-IV or any of its Restricted Subsidiaries (1) on its Capital Stock or (2)
with respect to any other interest or participation in, or measured by, its
profits, or (b) pay any Indebtedness owed to ICP-IV or any of its Restricted
Subsidiaries; (ii) make loans or advances to ICP-IV or any of its Restricted
Subsidiaries; or (iii) transfer any of its properties or assets to ICP-IV or any
of its Restricted Subsidiaries, except for such encumbrances or restrictions
existing under or by reason of (a) Indebtedness as in effect on the Issue Date,
(b) the Bank Facility as in effect as of the Issue Date, 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 with respect to such
dividend and other payment restrictions than those contained in the Bank
Facility as in effect on the Issue Date, (c) this Indenture and the Notes, (d)
applicable law, (e) any other Indebtedness permitted by the terms of this
Indenture to be incurred, provided that the restrictions contained in the
agreements governing such other Indebtedness are no more restrictive than those
contained in the Bank Facility, (f) customary non-assignment provisions in
leases entered into in the ordinary course of business and consistent with past
practices, or (g) Permitted Refinancing Debt, provided that the restrictions
contained in the agreements governing such Permitted Refinancing Debt are no
more restrictive than those contained in the agreements governing the
Indebtedness being refinanced.

SECTION 4.09.   INCURRENCE OF INDEBTEDNESS AND ISSUANCE OF PREFERRED EQUITY.

           ICP-IV shall not, and shall not permit any of its Restricted
Subsidiaries to, directly or indirectly, create, incur, issue, assume, guarantee
or otherwise become directly or indirectly liable, contingently or otherwise,
with respect to (collectively, "incur") any Indebtedness (including Acquired
Debt) and that ICP-IV will not issue any Disqualified Stock and will not permit
any of its Restricted Subsidiaries to issue any shares of Preferred Equity,
except the RMH Redeemable Preferred Stock in an amount up to $12.0 million as of
the date of this Indenture; provided,


                                       44
   53
however, that ICP-IV or any of its Restricted Subsidiaries may incur
Indebtedness (including Acquired Debt) and ICP-IV may issue Disqualified Stock
if ICP-IV's Leverage Ratio at the time of incurrence of such Indebtedness or
issuance of such Disqualified Stock, as applicable, 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 full fiscal quarter of ICP-IV for which consolidated financial statements
are available, would have been no greater than 8.0 to 1.0. if before January 1,
1998 or 7.5 to 1.0 if on or after January 1, 1998.

      The foregoing provisions shall not apply to the incurrence of any of the
following Indebtedness (collectively, "Permitted Debt"):

           (i) the incurrence by ICP-IV and its Restricted Subsidiaries of
      Indebtedness (including all Obligations with respect thereto) under the
      Revolving Credit Facility in an aggregate principal amount of up to (a)
      $350.0 million prior to the consummation of the Viacom Nashville
      Acquisition or (b) $475.0 million following the consummation of the Viacom
      Nashville Acquisition, in each case, with letters of credit being deemed
      to have a principal amount equal to the maximum potential liability
      thereunder and less the aggregate amount of all repayments of principal
      under the Revolving Credit Facility, optional or mandatory (other than
      repayments that are immediately reborrowed), that have been made since the
      Issue Date;

           (ii) the incurrence by ICP-IV and its Restricted Subsidiaries of the
      Notes and the Indebtedness outstanding on the Issue Date, including,
      without limitation, the Term Loan;

           (iii) the incurrence by ICP-IV or any of its Restricted Subsidiaries
      of Permitted Refinancing Debt in exchange for, or the net proceeds of
      which are used to extend, refinance, renew, replace, defease or refund,
      Indebtedness that was permitted by this Indenture to be incurred;

           (iv) the incurrence by ICP-IV or any of its Restricted Subsidiaries
      of intercompany Indebtedness between or among ICP-IV and any of its
      Restricted Subsidiaries; provided, however, that (i) if ICP-IV is the
      obligor on such Indebtedness, such Indebtedness is expressly subordinate
      to the payment in full of all Obligations with respect to all of the Notes
      and (ii)(A) any subsequent issuance or transfer of Equity Interests that
      results in any such Indebtedness being held by a Person other than ICP-IV
      or a Restricted Subsidiary and (B) any sale or other transfer of any such
      Indebtedness to a Person that is not either ICP-IV or a Restricted
      Subsidiary shall be deemed, in each case, to constitute an incurrence of
      such Indebtedness by ICP-IV or such Restricted Subsidiary, as the case may
      be;


                                       45
   54
           (v) the incurrence by ICP-IV or any of its Restricted Subsidiaries of
      Hedging Obligations that are incurred for the purpose of fixing or hedging
      interest rate risk with respect to any floating rate Indebtedness that is
      permitted by the terms of this Indenture to be outstanding;

           (vi) the incurrence by ICP-IV's Unrestricted Subsidiaries of
      Non-Recourse Debt, provided, however, that if any such Indebtedness ceases
      to be Non-Recourse Debt of an Unrestricted Subsidiary, such event shall be
      deemed to constitute an incurrence of Indebtedness by a Restricted
      Subsidiary of ICP-IV;

           (vii) the incurrence by IPSE of the indebtedness represented by the
      TCIC Loan and BA Loan, provided that such loans are repaid substantially
      concurrently with the earlier of the consummation of the Viacom Nashville
      Acquisition or the failure of the Viacom Nashville Acquisition to be
      consummated; and

           (viii) the incurrence by ICP-IV or any of its Restricted Subsidiaries
      of Indebtedness (in addition to Indebtedness permitted by any other clause
      of this paragraph) in an aggregate principal amount at any time
      outstanding not to exceed $25.0 million.

SECTION 4.10.   ASSET SALES.

           ICP-IV shall not, and shall not permit any Restricted Subsidiary to:
(i) sell, lease, convey or otherwise dispose of any assets (including, without
limitation, by way of a sale and leaseback or similar arrangement) other than in
the ordinary course of business; provided that the sale, lease, conveyance or
other disposition of all or substantially all of the assets of ICP-IV and its
Restricted Subsidiaries taken as a whole shall be governed by the provisions of
Section 5.01 hereof and not by the provisions of this Section 4.10; or (ii)
issue or sell Equity Interests of any of ICP-IV's Subsidiaries, in the case of
either clause (i) or (ii), whether in a single transaction or a series of
related transactions (a) that have a fair market value in excess of $1.0 million
or (b) for aggregate net proceeds in excess of $1.0 million (each of the
foregoing an "Asset Sale"), unless (x) ICP-IV or such Restricted Subsidiary, as
the case may be, receives consideration at the time of such Asset Sale at least
equal to the fair market value (as evidenced by a resolution of ICP-IV's Board
of Directors set forth in an Officers' Certificate delivered to the Trustee) of
the assets, or other property issued or sold or otherwise disposed of in the
Asset Sale; and (y) at least 75.0% of such consideration is in the form of cash
or Cash Equivalents. Notwithstanding the foregoing, none of the following shall
be deemed to be an Asset Sale: (i) the D.D. Cable Transactions; (ii) a transfer
of assets by ICP-IV to a Restricted Subsidiary or by a Restricted Subsidiary to
ICP-IV or to another Restricted Subsidiary; (iii) an issuance of Equity
Interests by a Restricted Subsidiary to ICP-IV or to another


                                       46
   55
Restricted Subsidiary; (iv) the sale of AVR Interests in accordance with the
terms of an agreement substantially similar to the AVR Letter of Intent; or (v)
any Restricted Payment or Permitted Investment that is permitted by Section 4.07
hereof.

           Notwithstanding the immediately preceding paragraph, ICP-IV and its
Restricted Subsidiaries may consummate an Asset Sale without complying with such
paragraph if (i) ICP-IV or the applicable Restricted Subsidiary, as the case may
be, receives consideration at the time of such Asset Sale at least equal to the
fair market value of the assets or other property sold, issued or otherwise
disposed of (as evidenced by a resolution of ICP-IV's Board of Directors set
forth in an Officers' Certificate delivered to the Trustee), and (ii) at least
75% of the consideration for such Asset Sale constitutes assets or other
property of a kind usable by ICP-IV and its Restricted Subsidiaries in the
business of ICP-IV and its Restricted Subsidiaries as conducted by ICP-IV and
its Restricted Subsidiaries on the Issue Date; provided that any consideration
not constituting assets or property of a kind usable by ICP-IV and its
Restricted Subsidiaries in the business conducted by them on the date of such
Asset Sale received by ICP-IV or any of its Restricted Subsidiaries in
connection with any Asset Sale permitted to be consummated under this paragraph
shall constitute Net Proceeds subject to the provisions of the two succeeding
paragraphs.

           Within 180 days after any Asset Sale, ICP-IV may apply the Net
Proceeds from such Asset Sale, to (a) permanently reduce any Indebtedness of any
Restricted Subsidiary of ICP-IV under the Bank Facility and/or (b) commit in
writing to the Trustee to make an investment in or acquire assets or property of
a kind usable by ICP-IV and its Restricted Subsidiaries in the business
conducted by them on the date of such Asset Sale or a business reasonably
related thereto and consummate such investment or acquisition within 360 days
after such Asset Sale, provided, however, that if at any time any non-cash
consideration received by ICP-IV or any Restricted Subsidiary of ICP-IV, as the
case may be, in connection with any Asset Sale is converted into or sold or
otherwise disposed of for cash, then such cash shall be deemed to constitute Net
Proceeds and shall be required to be applied in accordance with clauses (a)
and/or (b) above. Pending the final application of any such Net Proceeds, ICP-IV
may temporarily invest such Net Proceeds in any manner not prohibited by this
Indenture. Any Net Proceeds from an Asset Sale not applied or invested as
provided in the first sentence of this paragraph will be deemed to constitute
"Excess Proceeds."

           As soon as practical, but in no event later than 180 business after
any date that the aggregate amount of Excess Proceeds exceeds $5.0 million (an
"Asset Sale Offer Trigger Date"), ICP-IV shall commence an Asset Sale Offer
pursuant to Section 3.09 hereof to purchase the maximum principal amount of
Notes that may be


                                       47
   56
purchased out of the Excess Proceeds at an offer price in cash in an amount
equal to 100.0% of the principal amount thereof, plus accrued and unpaid
interest and Liquidated Damages thereon, if any, to the date of purchase in
accordance with the procedures set forth in Section 3.09 hereof. To the extent
that the aggregate amount of Notes tendered pursuant to an Asset Sale Offer is
less than the Excess Proceeds, ICP-IV (or such Subsidiary) may use such excess
for general corporate purposes. Upon completion of such offer to purchase, the
amount of Excess Proceeds shall be deemed to be reset at zero.

SECTION 4.11.   TRANSACTIONS WITH AFFILIATES.

           ICP-IV shall not, and shall not permit any of its Restricted
Subsidiaries to, directly or indirectly, conduct any business or enter into or
suffer to exist any transaction or series of transactions (including the
purchase, sale, transfer, lease or exchange of any Property or the rendering of
any service) with, or for the benefit of, any Affiliate (an "Affiliate
Transaction") unless: (i) the terms of such Affiliate Transaction are in
writing; (ii) such Affiliate Transaction is in the best interest of ICP-IV or
such Restricted Subsidiary, as the case may be; (iii) such Affiliate Transaction
is on terms at least as favorable to ICP-IV or such Restricted Subsidiary, as
the case may be, as those that could be obtained at the time of such Affiliate
Transaction for a similar transaction in arms-length dealings with a Person who
is not such an Affiliate; (iv) with respect to each Affiliate Transaction
involving aggregate payments or consideration in excess of $5.0 million, ICP-IV
delivers to the Trustee an Officers' Certificate certifying that such Affiliate
Transaction was approved by an Executive Officer of ICP-IV and that such
Affiliate Transaction complies with clauses (ii) and (iii) of this paragraph;
and (v) with respect to each Affiliate Transaction involving aggregate payments
or consideration in excess of $25.0 million, ICP-IV delivers to the Trustee, in
addition to those documents required by clause (iv) of this paragraph, an
opinion letter from an Independent Appraiser to the effect that such Affiliate
Transaction is fair to the Holders from a financial point of view.

           Notwithstanding the immediately preceding paragraph: (i) any
transaction pursuant to any contract in existence on the Issue Date in
accordance with the terms thereof as in effect on the Issue Date, including
contracts for the acquisition of cable television programming and renewals,
extensions and replacements thereof on terms no less favorable to ICP-IV and its
Restricted Subsidiaries than those in effect on the Issue Date; (ii)
transactions permitted under Section 4.07; (iii) any transaction or series of
transactions between ICP-IV and one or more of its Restricted Subsidiaries or
between two or more of its Restricted Subsidiaries (provided that no more than
10.0% of the equity interest in any of such Restricted Subsidiaries is owned by
an Affiliate that is not itself a Restricted Subsidiary); (iv) the payment of
compensation (including


                                       48
   57
amounts paid pursuant to employee benefit plans) for the personal services of
officers, directors and employees of ICP-IV or any of its Restricted
Subsidiaries, or any consultant or advisor thereto, so long as the Board of
Directors of ICP-IV in good faith shall have approved the terms thereof and
deemed the services theretofore or thereafter to be performed for such
compensation or fees to be fair consideration therefor; (v) any sale of Equity
Interests of ICP-IV; and (vi) the D.D. Cable Transactions shall not be deemed
Affiliate Transactions.

SECTION 4.12.   LIENS.

           ICP-IV shall not, and shall not permit any of its Subsidiaries to,
directly or indirectly, create, incur, assume or suffer to exist any Lien (other
than Permitted Liens) upon any of its Property, or the Property of such
Subsidiaries whether now owned or hereafter acquired, or any interest therein or
any income or profits therefrom, unless it has made or will make effective a
provision whereby all payments due under this Indenture and the Notes will be
secured by such Lien equally and ratably with (or prior to) all other
Indebtedness of ICP-IV or such Subsidiary secured by such Lien for so long as
any such other Indebtedness of ICP-IV or such Subsidiary shall be so secured.

SECTION 4.13.   LIMITATION ON CONDUCT OF IPCC.

           IPCC shall not acquire or hold any significant assets or other
properties or engage in any business activities; provided, however, that IPCC
may be a co-obligor with respect to Indebtedness if ICP-IV is a primary obligor
or guarantor with respect to such Indebtedness and the net proceeds of such
Indebtedness are loaned to ICP-IV.

SECTION 4.14.   CORPORATE OR PARTNERSHIP EXISTENCE.

           Subject to Article 5 hereof, each of ICP-IV and IPCC shall do or
cause to be done all things necessary to preserve and keep in full force and
effect (i) its corporate or partnership existence, as applicable, and the
corporate, partnership or other existence of each of its Restricted
Subsidiaries, in accordance with the respective organizational documents (as the
same may be amended from time to time) of ICP-IV or any such Restricted
Subsidiary and (ii) the rights (charter and statutory), licenses and franchises
of ICP-IV and its Restricted Subsidiaries; provided, however, that ICP-IV shall
not be required to preserve any such right, license or franchise, or the
corporate, partnership or other existence of any of its Restricted Subsidiaries,
if the Board of Directors shall determine that the preservation thereof is no
longer desirable in the conduct of the business of ICP-IV and its Restricted
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) Within 30 days of the occurrence of a Change of Control, ICP-IV
shall notify the Trustee in writing of such proposed occurrence and shall make
an offer to purchase (a "Change of Control Offer") the Notes at a purchase price
equal to 101.0% of the principal amount thereof plus accrued and unpaid interest
and Liquidated Damages thereon, if any, to the Change of Control Payment Date
(the "Change of Control Purchase Price"). ICP-IV shall not be required to make a
Change of Control Offer upon the occurrence of a Change of Control if a third
party makes the Change of Control Offer in the manner, at the times and
otherwise in compliance with the requirements set forth in this Indenture and
purchases all Notes validly tendered and not withdrawn under such Change of
Control Offer. Within 50 days of the occurrence of a Change of Control, ICP-IV
shall also: (i) cause a notice of the Change of Control Offer to be sent at
least once to the Dow Jones News Service or similar business news service in the
United States and (ii) send by first-class mail, postage prepaid, to the Trustee
and to each registered Holder of Notes, at its address appearing in the register
of the Notes maintained by the Registrar, a notice stating: (A) 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, subject to the terms and conditions set
forth herein; (B) the Change of Control Purchase Price and the purchase date
(which shall be a Business Day no earlier than 30 days and no later than 60 days
after the date on which such notice is mailed) (the "Change of Control Payment
Date"); (C) that any Note not tendered will continue to accrue interest; (D)
that unless ICP-IV defaults in the payment of the Change of Control Purchase
Price, any such Notes accepted for payment pursuant to the Change of Control
Offer will cease to accrue interest after the Change of Control Payment Date;
(E) that Holders accepting the offer to have their Notes purchased pursuant to a
Change of Control Offer will be required to surrender such Notes to the Paying
Agent at the address specified in the notice prior to the close of business on
the Business Day preceding the Change of Control Payment Date; (F) that Holders
will be entitled to withdraw their acceptance if the Paying Agent receives, not
later than the close of business on the third 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 such Notes delivered for purchase,
and a statement that such Holder is withdrawing its election to have such Notes
purchased; (G) 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, provided that each Note purchased and each such new Note
issued shall be in an original principal amount in denominations of $1,000 and
integral multiples thereof; and (H) any other procedures that a Holder must
follow to accept a Change of Control Offer or effect withdrawal of such
acceptance. The Issuers shall comply, to the extent applicable, with the
requirements of Section 14(e) the


                                       50
   59
Exchange Act and any other securities laws and regulations in connection
with the repurchase of Notes in connection with a Change of Control and, to the
extent that the provisions of such securities laws or regulations conflict with
this Section 4.15, the Issuers shall not be deemed to have breached their
obligations under this Section 4.15 by virtue thereof.

           (b) On the Change of Control Payment Date, ICP-IV shall, to the
extent lawful, (i) accept for payment all the Notes or portions thereof properly
tendered pursuant to the Change of Control Offer, (ii) 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 (iii) 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 tendered to ICP-IV.
The Paying Agent shall promptly mail to each Holder of Notes so accepted payment
in an amount equal to the purchase price for the Notes, and the Trustee shall
promptly authenticate and mail to such 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.

           (c) The Change of Control provisions described herein shall be
applicable whether or not any other provisions of this Indenture are applicable.

SECTION 4.16.   OWNERSHIP OF OPERATING PARTNERSHIP.

           ICP-IV shall continue to own at least 99.99% of the outstanding
Equity Interests of the Operating Partnership or any successor to all or
substantially all of the Operating Partnership's assets.

SECTION 4.17.   CONSUMMATION OF THE VIACOM NASHVILLE ACQUISITION.

           ICP-IV shall, and shall cause each of its Subsidiaries to, use its
best efforts to consummate the Viacom Nashville Acquisition on substantially the
terms described in the Offering Memorandum and to cause the Viacom Nashville
System to be transferred to a Restricted Subsidiary of ICP-IV.

SECTION 4.18.   DESIGNATION OF RESTRICTED AND UNRESTRICTED SUBSIDIARIES.

           The Board of Directors may designate any Unrestricted Subsidiary to
be a Restricted Subsidiary at any time; provided, however, that immediately
after giving effect to such designation on a pro forma basis as if the same had
occurred at the beginning of the most recently ended full fiscal quarter of
ICP-IV for which consolidated financial statements are available, (i) ICP-IV
would be permitted to incur at least $1.00 of additional Indebtedness

                                       51
   60
(other than Permitted Debt) pursuant to Section 4.09, (ii) there exist no Liens
(other than Permitted Liens) on the Property of ICP-IV or its Restricted
Subsidiaries and (iii) an Officers' Certificate with respect to such designation
is delivered to the Trustee within 75 days after the end of the fiscal quarter
of ICP-IV in which such designation is made (or, in the case of a designation
made during the last fiscal quarter of ICP-IV's fiscal year, within 120 days
after the end of such fiscal year), which Officers' Certificate states the
effective date of such designation; and provided, further, that such designation
shall be deemed to be an incurrence of Indebtedness by a Restricted Subsidiary
of ICPIV of any outstanding Indebtedness of such Unrestricted Subsidiary and
such designation shall only be permitted if no Default or Event of Default would
be in existence following such designation. The provisions of this paragraph
shall not be applicable to the designation of IPSE as a Restricted Subsidiary of
ICP-IV following the consummation of the Viacom Nashville Acquisition.

      The Board of Directors may designate any Restricted Subsidiary, other than
IPCC, to be an Unrestricted Subsidiary if such designation would not cause a
Default; provided, however, that immediately after giving effect to such
designation on a pro forma basis, ICP-IV would be in compliance with Section
4.07 hereof. For purposes of making such determination, all outstanding
Investments by ICP-IV and its Restricted Subsidiaries (except to the extent
repaid in cash) in the Subsidiary so designated, whether made before or after
the Issue Date, shall be deemed to be Restricted Payments at the time of such
designation and shall reduce the amount available for Restricted Payments. All
such outstanding Investments shall be deemed to constitute Investments in an
amount equal to the greatest of (i) the net book value of such Investments at
the time of such designation, (ii) the fair market value of such Investments at
the time of such designation and (iii) the original fair market value of such
Investments at the time they were made. Such designation shall only be permitted
if such Restricted Payment would be permitted at such time and if such
Restricted Subsidiary otherwise meets the definition of an Unrestricted
Subsidiary.

SECTION 4.19.   SUSPENDED COVENANTS.

           If, at any time, (i) the ratings assigned to the Notes by both of the
Rating Agencies are Investment Grade Ratings and (ii) no Default has occurred
and is continuing, ICP-IV and its Restricted Subsidiaries shall thereafter cease
to be subject to the provisions of Sections 4.07, 4.08, 4.09, 4.10, 4.11 and
4.18 hereof and clause (iv) of Section 5.01 hereof (the "Suspended Covenants").
In the event that ICP-IV and its Restricted Subsidiaries are not subject to the
Suspended Covenants with respect to the Notes for any period of time as a result
of the preceding sentence and, subsequently, one or both Ratings Agencies
withdraws its ratings or downgrades the ratings assigned to such Notes below the
required

                                       52
   61
Investment Grade Ratings, then ICP-IV and its Restricted Subsidiaries shall
thereafter again be subject to the Suspended Covenants for the benefit of such
Notes and compliance with the Suspended Covenants with respect to Restricted
Payments made after the time of such withdrawal or downgrade shall be calculated
in accordance with the terms of Section 4.07 as if such Section had been in
effect during the entire period of time from the Issue Date.

SECTION 4.20    PAYMENTS FOR CONSENT.

           Neither ICP-IV nor any of its Subsidiaries shall, directly or
indirectly, pay or cause to be paid any consideration, whether by way of
interest, fee or otherwise, to any Holder of any Note for or as an inducement to
any consent, waiver or amendment of any of the terms of provisions of this
Indenture or the Notes, unless such consideration is offered to be paid or is
paid to all Holders of the Notes that consent, waive or agree to amend in the
time frame set forth in the solicitation documents relating to such consent,
waiver or agreement.

SECTION 4.21.   SECURITY.

           (a) The Issuers shall: (i) enter into the Pledge Agreement (in the
form attached hereto as Exhibit C) and comply with the terms and provisions
thereof; and (ii) use a portion of the net proceeds of the Offering to purchase
the Pledged Securities to be pledged to the Collateral Agent for the benefit of
the Holders of the Notes in such amount as shall be sufficient upon receipt of
scheduled interest and principal payments of such securities, in the opinion of
a nationally recognized firm of independent public accountants selected by the
Issuers, to provide for payment in full of the first six scheduled interest
payments due on the Notes. The Pledged Securities shall be pledged by the
Issuers to the Collateral Agent for the benefit of the Holders of the Notes and
shall be held by the Collateral Agent in the Pledge Account pending disbursement
pursuant to the Pledge Agreement.

           (b) Each Holder, by its acceptance of a Note, consents and agrees to
the terms of the Pledge Agreement (including, without limitation, the provisions
providing for foreclosure and release of Collateral) as the same may be in
effect or may be amended from time to time in accordance with its terms, and
authorizes and directs each of the Trustee and the Collateral Agent to enter
into the Pledge Agreement and to perform its respective obligations and exercise
its respective rights thereunder in accordance therewith. The Issuers shall do
or cause to be done all such acts and things as may be necessary or proper, or
as may be required by the provisions of the Pledge Agreement, to assure and
confirm to the Trustee and the Collateral Agent the security interest in the
Collateral contemplated hereby, by the Pledge Agreement or any part thereof, as
from time to time constituted, so as to render the same

                                       53
   62
available for the security and benefit of this Indenture and of the Notes
secured hereby, according to the intent and purposes herein expressed. The
Issuers shall take, or shall cause to be taken, any and all actions reasonably
required to cause the Pledge Agreement to create and maintain, as security for
the obligations of the Issuers under this Indenture and the Notes, valid and
enforceable first priority liens (collectively, the "Pledged Securities Lien")
in and on all the Collateral, in favor of the Collateral Agent, superior to and
prior to the rights of all third Persons and subject to no other Liens other
than as provided herein.

         (c) The release of any Collateral pursuant to the Pledge Agreement
shall not be deemed to impair the security under this Indenture in contravention
of the provisions hereof if and to the extent the Collateral is released
pursuant to this Indenture and the Pledge Agreement. To the extent applicable,
the Issuers shall cause TIA Section 314(d) relating to the release of property
or securities from the Pledged Securities Lien and security interest of the
Pledge Agreement and relating to the substitution therefor of any property or
securities to be subjected to the Pledged Securities Lien and security interest
of the Pledge Agreement to be complied with. Any certificate or opinion required
by TIA Section 314(d) may be made by an Officer of each of the Issuers, except
in cases where TIA Section 314(d) requires that such certificate or opinion be
made by an independent Person, which Person shall be a reputable independent
engineer, appraiser or other expert selected or approved by the Issuers in the
exercise of reasonable care.

           (d) The Issuers shall cause TIA Section 314(b), relating to opinions
of counsel regarding the Pledged Securities Lien of the Pledge Agreement, to be
complied with. The Issuers shall furnish the following to the Collateral Agent
and the Trustee prior to each proposed release of Collateral pursuant to the
Pledge Agreement: (i) all documents required by TIA Section 314(d); and (ii) an
Opinion of Counsel to the effect that such accompanying documents constitute all
documents required by TIA Section 314(d). The Trustee may, to the extent
permitted by Sections 7.01 and 7.02 hereof, accept as conclusive evidence of
compliance with the foregoing provisions the appropriate statements contained in
such instruments.

           (e) The Collateral Agent may, in its sole discretion and without the
consent of the Holders, on behalf of the Holders, take all actions it deems
necessary or appropriate in order to (i) enforce any of the terms of the Pledge
Agreement and (ii) collect and receive any and all amounts payable in respect of
the obligations of the Issuers hereunder. The Collateral Agent shall have power
to institute and to maintain such suits and proceedings as it may deem expedient
to prevent any impairment of the Collateral by any acts that may be unlawful or
in violation of the Pledge Agreement or this Indenture, and such suits and
proceedings as either the Collateral Agent may deem expedient to preserve or
protect its interests and the interests of the Holders in the

                                       54
   63
Collateral (including power to institute and maintain suits or proceedings to
restrain the enforcement of or compliance with any legislative or other
governmental enactment, rule or order that may be unconstitutional or otherwise
invalid if the enforcement of, or compliance with, such enactment, rule or order
would impair the security interest hereunder or be prejudicial to the interests
of the Holders or of the Collateral Agent.

                                   SUCCESSORS

SECTION 5.01.   MERGER, CONSOLIDATION, OR SALE OF ASSETS.

           ICP-IV shall not consolidate with or merge with or into (whether or
not ICP-IV is the surviving Person) or convey, sell, assign, transfer, lease or
otherwise dispose of all or substantially all of its properties or assets (as an
entirety or substantially as an entirety in a transaction or a series of related
transactions) to any Person unless: (i) ICP-IV will be the surviving Person (the
"Surviving Person"), or the Surviving Person (if other than the ICP-IV) formed
by or surviving any such consolidation or merger or to which such sale,
assignment, transfer, lease, conveyance or other disposition shall have been
made is a corporation organized or existing under the laws of the United States,
any state thereof or the District of Columbia; (ii) the Surviving Person (if
other than ICP-IV) expressly assumes, by supplemental indenture, executed and
delivered to the Trustee, in form satisfactory to the Trustee, all of the
obligations of ICP-IV under the Notes and this Indenture, and the obligations
under this Indenture remain in full force and effect, (iii) immediately before
and immediately after giving effect to such transaction, no Default or Event of
Default shall have occurred and be continuing, and (iv) immediately after giving
effect to such transaction on a pro forma basis as if the same had occurred at
the beginning of the most recently ended full fiscal quarter of ICP-IV for which
consolidated financial statements are available (including any Indebtedness
incurred or anticipated to be incurred in connection with such transaction or
series of transactions), the Surviving Person would be permitted to incur at
least $1.00 of additional Indebtedness (other than Permitted Debt) pursuant to
the Leverage Ratio test applicable to ICP-IV set forth in the proviso of the
first paragraph of Section 4.09 hereof.

           In connection with any consolidation, merger or transfer contemplated
by this provision, ICP-IV shall deliver, or cause to be delivered, to the
Trustee, in form and substance reasonably satisfactory to the Trustee, an
Officers' Certificate and an Opinion of Counsel, each stating that such
consolidation, merger or transfer and the supplemental indenture in respect
thereto comply with this provision and that all conditions precedent in this
Indenture provided for relating to such transaction or transactions have been
complied with.

                                       55
   64
           Notwithstanding the foregoing, ICP-IV is permitted to reorganize as a
corporation in accordance with the procedures established in this Indenture,
provided that ICP-IV shall have delivered to the Trustee an Opinion of Counsel
in the United States reasonably acceptable to the Trustee confirming that such
reorganization is not adverse to Holders of the Notes (it being recognized that
such reorganization shall not be deemed adverse to the Holders of the Notes
solely because (A) of the accrual of deferred tax liabilities resulting from
such reorganization or (B) the successor or surviving corporation (a) is subject
to income tax as a corporate entity or (b) is considered to be an "includible
corporation" of an affiliated group of corporations within the meaning of the
Code or any similar state or local law).

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 ICP-IV in accordance with Section 5.01 hereof, the Surviving Person formed by
such consolidation or into or with which ICP-IV 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 "ICP-IV" shall refer instead to the
Surviving Person and not to ICP-IV), and may exercise every right and power of
ICP-IV under this Indenture with the same effect as if such Surviving Person had
been named as ICP-IV herein; provided, however, that ICP-IV shall not be
relieved from the obligation to pay the principal of and interest on the Notes
except in the case of a sale of all of ICP-IV'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) (i) ICP-IV defaults in the payment when due of interest on
           the Notes on any day on or prior to August 1, 1999, or (ii) ICP-IV
           defaults in the payment when due of interest on the Notes on any day
           after August 1, 1999 and such default continues for a period of 30
           days;

                (b) ICP-IV defaults in the 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;

                                       56
   65
                (c) ICP-IV fails to observe or perform any other covenant,
           representation, warranty or other agreement in this Indenture or the
           Notes for 30 days after notice to ICP-IV by the Trustee or the
           Holders of at least 25.0% in principal amount of the Notes then
           outstanding;

                (d) 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 ICP-IV or any of its
           Restricted Subsidiaries (or the payment of which is guaranteed by
           ICPIV or any of its Restricted Subsidiaries), whether such
           Indebtedness or guarantee now exists, or is created after the Issue
           Date, which default (i) is caused by a failure to pay principal of or
           premium, if any, or interest on such Indebtedness prior to the
           expiration of such grace period provided in such Indebtedness on the
           date of such default (a "Payment Default") or (ii) 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 $10.0 million or more, which Payment Default
           shall not be cured or waived, or which acceleration shall not be
           rescinded or annulled, within 10 days after written notice thereof;

                (e) a final judgment or final judgments for the payment of money
           are entered by a court or courts of competent jurisdiction against
           ICP-IV or any of its Restricted Subsidiaries and such judgment or
           judgments remain undischarged for a period (during which execution
           shall not be effectively stayed) of 30 consecutive days, provided
           that the aggregate of all such undischarged judgments exceeds $10.0
           million;

                  (f) ICP-IV or any of its Restricted Subsidiaries pursuant to
         or within the meaning of Bankruptcy Law:

                      (i)  commences a voluntary case,

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

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

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

                                       57
   66
                      (v) generally is not paying its debts as they become due;
                or

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

                      (i) is for relief against ICP-IV or any of its Restricted
                Subsidiaries in an involuntary case;

                      (ii) appoints a Bankruptcy Custodian of ICP-IV or any of
                its Restricted Subsidiaries for all or substantially all of the
                property of ICP-IV or any of its Restricted Subsidiaries; or

                      (iii) orders the liquidation of ICP-IV or any of its
                Restricted Subsidiaries;

           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 (f) or (g) of Section 6.01 hereof with respect to ICP-IV or any of its
Restricted Subsidiaries) occurs and is continuing, the Trustee or the Holders of
at least 25.0% in principal amount of the then outstanding Notes may declare all
the Notes to be due and payable immediately. Upon any such declaration, the
Notes shall become due and payable immediately. Notwithstanding the foregoing,
if an Event of Default specified in clause (f) or (g) of Section 6.01 hereof
occurs with respect to ICP-IV or any of its Restricted Subsidiaries 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 premium that has become due solely
because of the acceleration) have been cured or waived.

           Upon the acceleration of the Notes under this Section 6.02, the
Collateral Agent shall, at the Trustee's direction, liquidate the Pledged
Securities and apply the proceeds thereof to the principal, interest and
Liquidated Damages, if any, on the Notes to the date of such acceleration.

           If an Event of Default occurs on or after August 1, 2001 by reason of
any willful action (or inaction) taken (or not taken) by or on behalf of ICP-IV
with the intention of avoiding payment of the premium that ICP-IV would have had
to pay if ICP-IV then had elected to redeem the Notes pursuant to Section 3.07
hereof, then,

                                       58
   67
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 August 1, 2001 by reason of any willful action (or
inaction) taken (or not taken) by or on behalf of ICP-IV 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
August 1 of the years set forth below, as set forth below (expressed as
percentages of principal amount:

                  YEAR                                      PERCENTAGE
                  ____                                      __________

                  1997......................................      111.250%
                  1998......................................      109.849%
                  1999......................................      108.438%
                  2000 .....................................      107.031%
                  2001......................................      105.625%


SECTION 6.03.   OTHER REMEDIES.

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

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

SECTION 6.04.   WAIVER OF PAST DEFAULTS.

           Holders of not less than a majority in aggregate principal amount of
the then outstanding Notes by notice to the Trustee may on behalf of the Holders
of all of the Notes waive an existing Default or Event of Default and its
consequences hereunder, except a continuing Default or Event of Default in the
payment of interest on, or the principal of, the Notes (including in connection
with an offer to purchase). 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.

                                       59
   68
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 Note 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 25.0% in principal amount of the then
      outstanding Notes make a written request to the Trustee to pursue the
      remedy;

           (c) such Holder of a Notes 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 Notes may not use this Indenture to prejudice the rights of
another Holder of a Notes or to obtain a preference or priority over another
Holder of a Notes.

SECTION 6.07.   RIGHTS OF HOLDERS OF NOTES TO RECEIVE PAYMENT.

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

                                       60
   69
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 ICP-IV 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 ICP-IV (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:

                                       61
   70
         First: to the Trustee, its agents and attorneys for amounts due under
Section 7.07 hereof, including payment of all compensation, expense and
liabilities incurred, and all advances made, by the Trustee and the costs and
expenses of collection;

         Second: to Holders of Notes for amounts due and unpaid on the Notes for
principal, premium, 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 ICP-IV or to such party as a court of competent jurisdiction
shall direct.

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

SECTION 6.11.   UNDERTAKING FOR COSTS.

           In any suit for the enforcement of any right or remedy under this
Indenture or in any suit against the Trustee for any action taken or omitted by
it as a Trustee, a court in its discretion may require the filing by any party
litigant in the suit of an undertaking to pay the costs of the suit, and the
court in its discretion may assess reasonable costs, including reasonable
attorneys' fees and expenses, against any party litigant in the suit, having due
regard to the merits and good faith of the claims or defenses made by the party
litigant. This Section does not apply to a suit by the Trustee, a suit by a
Holder of a Note pursuant to Section 6.07 hereof, or a suit by Holders of more
than 10.0% 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
his or her own affairs.

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

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

                                       62
   71
         obligations shall be read into this Indenture against the Trustee; and

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

                  (iii) the Trustee shall not be liable with respect to any
         action it takes or omits to take in good faith in accordance with a
         direction received by it pursuant to Section 6.05 hereof.

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

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

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

SECTION 7.02.   RIGHTS OF TRUSTEE.

           (a) The Trustee may conclusively rely upon any document believed by
it to be genuine and to have been signed or presented

                                       63
   72
by the proper Person. The Trustee need not investigate any fact or matter stated
in the document.

           (b) Before the Trustee acts or refrains from acting, it may require
an Officers' Certificate or an Opinion of Counsel or both. The Trustee shall not
be liable for any action it takes or omits to take in good faith in reliance on
such Officers' Certificate or Opinion of Counsel. The Trustee may consult with
counsel of its selection and the advice of such counsel or any Opinion of
Counsel shall be full and complete authorization and protection from liability
in respect of any action taken, suffered or omitted by it hereunder in good
faith and in reliance thereon.

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

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

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

           (f) The Trustee shall be under no obligation to exercise any of the
rights or powers vested in it by this Indenture at the request or direction of
any of the Holders unless such Holders shall have offered to the Trustee
reasonable security or indemnity 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 ICP-IV 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 ICP-IV's use of the proceeds from the Notes or any money paid to
ICP-IV or upon ICP-IV's direction under any provision of this Indenture, it
shall not be responsible for the use or application of any money received by

                                       64
   73
any Paying Agent other than the Trustee, and it shall not be responsible for any
statement or recital herein or any statement in the Notes or any other document
in connection with the sale of the Notes or pursuant to this Indenture other
than its certificate of authentication.

SECTION 7.05.   NOTICE OF DEFAULTS.

           If a Default or Event of Default occurs and is continuing and if it
is known to the Trustee, the Trustee shall mail to Holders of Notes a notice of
the Default or Event of Default within 90 days after it occurs. Except in the
case of a Default or Event of Default in payment of principal of, premium, if
any, or interest on any Notes, 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 Section 313(a) (but if no event described
in TIA Section 313(a) has occurred within the twelve months preceding the
reporting date, no report need be transmitted). The Trustee also shall comply
with TIA Section 313(b)(2) and Section 313(b)(1). The Trustee shall also
transmit by mail all reports as required by TIA Section 313(c).

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

SECTION 7.07.   COMPENSATION AND INDEMNITY.

           ICP-IV shall pay to the Trustee from time to time such compensation
as shall be agreed between ICP-IV and the Trustee for its acceptance of this
Indenture and services hereunder. The Trustee's compensation shall not be
limited by any law on compensation of a trustee of an express trust. ICP-IV
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.

           ICP-IV shall indemnify each of the Trustee and any predecessor
Trustee against any and all losses, liabilities, damages, claims or expenses,
including taxes (other than taxes

                                       65
   74
based on the income of the Trustee), incurred by it arising out of or in
connection with the acceptance or administration of its duties under this
Indenture, including the costs and expenses of enforcing this Indenture against
the 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 ICP-IV
promptly of any claim for which it may seek indemnity. Failure by the Trustee to
so notify ICP-IV shall not relieve ICP-IV of its obligations hereunder. ICP-IV
shall defend the claim and the Trustee shall cooperate in the defense. The
Trustee may have separate counsel and ICP-IV shall pay the reasonable fees and
expenses of such counsel. ICP-IV need not pay for any settlement made without
its consent, which consent shall not be unreasonably withheld.

           The obligations of ICP-IV under this Section 7.07 shall survive the
satisfaction and discharge of this Indenture.

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

           When the Trustee incurs expenses or renders services after an Event
of Default specified in Section 6.01(f) or (g) 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 Section 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 ICP-IV. The Holders of Notes of a
majority in principal amount of the then outstanding Notes may remove the
Trustee by so notifying the Trustee and ICP-IV in writing. ICP-IV may remove the
Trustee if:

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

                                       66
   75
           (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 Bankruptcy 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, ICP-IV 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 ICP-IV.

           If a successor Trustee does not take office within 60 days after the
retiring Trustee resigns or is removed, the retiring Trustee, ICP-IV, or the
Holders of Notes 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 of a Note who has
been a Holder of a Note for at least six months, fails to comply with Section
7.10, such Holder of a Note 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 ICP-IV. 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 of the Notes. 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, ICP-IV's obligations under Section 7.07 hereof shall continue for the
benefit of the retiring Trustee.

SECTION 7.09.   SUCCESSOR TRUSTEE BY MERGER, ETC.

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

                                       67
   76
SECTION 7.10.   ELIGIBILITY; DISQUALIFICATION.

         There shall at all times be a Trustee hereunder that is a corporation
organized and doing business under the laws of the United States of America or
of any state thereof that is authorized under such laws to exercise corporate
trustee power, that is subject to supervision or examination by federal or state
authorities and that has a combined capital and surplus of at least $50 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 Section 310(a)(1), (2) and (5). The Trustee is subject to
TIA Section 310(b).

SECTION 7.11.   PREFERENTIAL COLLECTION OF CLAIMS AGAINST ISSUERS.

         The Trustee is subject to TIA Section 311(a), excluding any creditor
relationship listed in TIA Section 311(b). A Trustee who has resigned or been
removed shall be subject to TIA Section 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 Officers' Certificates, 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 (i) and (ii) 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

                                       68
   77
shall survive until otherwise terminated or discharged hereunder: (i) 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, if any, and interest (including Liquidated
Damages) on such Notes when such payments are due; (ii) the Issuers' obligations
with respect to such Notes under Article 2 and Section 4.02 hereof; (iii) the
rights, powers, trusts, duties and immunities of the Trustee hereunder and the
Issuers' obligations in connection therewith; and (iv) this Article Eight.
Subject to compliance with this Article 8, the Issuers may exercise their option
under this Section 8.02 notwithstanding the prior exercise of their option under
Section 8.03 hereof.

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 with respect to the
outstanding Notes on and after the date the conditions set forth below 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(d) 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:

                                       69
   78
           In order to exercise either Legal Defeasance or Covenant Defeasance:

                      (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, if any, and interest (if such deposit
           occurs prior to August 1, 1999, the Pledged Securities shall be
           applied toward the interest required to effect such Legal Defeasance
           or Covenant Defeasance) on the outstanding Notes on the stated date
           for payment thereof or on the applicable redemption date, as the case
           may be;

                      (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;

                      (d) no Default or Event of Default shall have occurred and
           be continuing on the date of such deposit (other than a Default or
           Event of Default resulting from the incurrence of Indebtedness all or
           a portion of the proceeds of which will be used to defease the Notes
           pursuant to this Article Eight concurrently with such incurrence) or
           insofar as Section 6.01(f) or 6.01(g) hereof is concerned, at any
           time in the period ending on the 91st day after the date of deposit;

                                       70
   79
                      (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 an Issuer or any of its Restricted Subsidiaries is a party or
           by which an Issuer or any of its Restricted Subsidiaries is bound;

                      (f) the Issuers shall have delivered to the Trustee an
           Opinion of Counsel to the effect that, as of the date such opinion,
           (i) the trust funds will not be subject to rights of holders of
           Indebtedness other than the Notes and (ii) assuming no intervening
           bankruptcy of either Issuer between the date of deposit and the 91st
           day following the deposit (assuming no Holder of Notes is an insider
           of either Issuer) or the day following the end of such other
           preference period in effect at the time of such opinion (assuming a
           Holder of Notes is an insider of either Issuer), as applicable,
           following the deposit, the trust funds will not be subject to the
           effects of any applicable bankruptcy, insolvency, reorganization or
           similar laws affecting creditors' rights generally under any
           applicable United States or state law;

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

                      (h) each Issuer shall have delivered to the Trustee an
           Officers' Certificate and an Opinion of Counsel, each stating that
           all conditions precedent provided for or 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 ICP-IV 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
(including Liquidated Damages), but such money need not be segregated from other
funds except to the extent required by law.

                                       71
   80
           ICP-IV 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 ICP-IV from time to time upon the request of
ICP-IV 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.

SECTION 8.06.   REPAYMENT TO ISSUERS.

           Any money deposited with the Trustee or any Paying Agent, or then
held by the Issuers, in trust for the payment of the principal of, premium, if
any, or interest on any Note and remaining unclaimed for two years after such
principal, and premium, if any, or interest has become due and payable shall be
paid to the Issuers on their request or (if then held by the Issuers) shall be
discharged from such trust; and the Holder of such Notes shall thereafter, as a
secured creditor, look only to the Issuers for payment thereof, and all
liability of the Trustee or such Paying Agent with respect to such trust money,
and all liability of the Issuers as trustee thereof, shall thereupon cease;
provided, however, that the Trustee or such Paying Agent, before being required
to make any such repayment, may at the expense of the Issuers cause to be
published once, in The New York Times and The Wall Street Journal (national
edition), notice that such money remains unclaimed and that, after a date
specified therein, which shall not be less than 30 days from the date of such
notification or publication, any unclaimed balance of such money then remaining
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;

                                       72
   81
provided, however, that, if ICP-IV makes any payment of principal of, premium,
if any, or interest on any Note following the reinstatement of its obligations,
the Issuers shall be subrogated to the rights of the Holders of such Notes to
receive such payment from the money held by the Trustee or Paying Agent.

                                    ARTICLE 9

                        AMENDMENT, SUPPLEMENT AND WAIVER

SECTION 9.01.   WITHOUT CONSENT OF HOLDERS OF NOTES.

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

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

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

           (c) to provide for the assumption of the ICP-IV's obligations to the
      Holders of the Notes in the case of a merger or consolidation pursuant to
      Article Five hereof;

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

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

           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 9.06 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 Sections 3.09, 4.10
and 4.15 hereof), the Pledge Agreement or the Notes with the consent of the
Holders of at least a majority in

                                       73
   82
principal amount of the Notes then outstanding (including, without limitation,
consents obtained in connection with a tender offer or exchange offer for 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 on the Notes, except a payment
default resulting from an acceleration that has been rescinded) or compliance
with any provision of this Indenture, the Pledge Agreement or the Notes may be
waived with the consent of the Holders of a majority in principal amount of the
then outstanding Notes (including consents obtained in connection with a tender
offer or exchange offer for the Notes).

         Upon the request of each of the Issuers accompanied by a resolution of
its Board of Directors authorizing the execution of any such amended or
supplemental Indenture, and upon the filing with the Trustee of evidence
satisfactory to the Trustee of the consent of the Holders of Notes as aforesaid,
and upon receipt by the Trustee of the documents described in Section 9.06
hereof, the Trustee shall join with the Issuers in the execution of such amended
or supplemental Indenture unless such amended or supplemental Indenture 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 then outstanding may waive
compliance in a particular instance by the Issuers with any provision of this
Indenture or the Notes. However, without the consent of each Holder affected, an
amendment or waiver 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 Notes or alter or waive any of the provisions with respect to the
         redemption of the Notes (except as provided above with respect to
         Sections 4.10 and 4.15 hereof);

                                       74
   83
                  (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, if any, or interest on the Notes (except a
         rescission of acceleration of the Notes by the Holders of at least a
         majority in aggregate principal amount of the then outstanding Notes
         and a waiver of the payment default that resulted from such
         acceleration);

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

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

                  (g) waive a redemption payment with respect to any Note (other
         than a payment required by Section 4.10 or 4.15 hereof);

                  (h) release any Collateral from the Pledged Securities Lien
         created by the Pledge Agreement, except in accordance with the terms
         thereof; or

                  (i) make any change 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.

                                       75
   84
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 authenticate new Notes
that reflect the amendment, supplement or waiver.

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

SECTION 9.06.   TRUSTEE TO SIGN AMENDMENTS, ETC.

           The Trustee shall sign any amended or supplemental Indenture
authorized pursuant to this Article 9 if the amendment or supplement does not
adversely affect the rights, duties, liabilities or immunities of the Trustee.
The Issuers may not sign an amendment or supplemental Indenture until the Board
of Directors of each Issuer approves it. In executing any amended or
supplemental indenture, the Trustee shall be entitled to receive and (subject to
Section 7.01) shall be fully protected in relying upon, Officers' Certificates
and Opinions of Counsel stating that the execution of such amended or
supplemental indenture is authorized or permitted by this Indenture.

                                   ARTICLE 10
                                  MISCELLANEOUS

SECTION 10.01.  TRUST INDENTURE ACT CONTROLS.

           If any provision of this Indenture limits, qualifies or conflicts
with the duties imposed by TIA Section 318(c), the imposed duties shall control.

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

         1. INTEREST. InterMedia Capital Partners IV, L.P., a California limited
partnership ("ICP-IV"), and InterMedia Partners IV Capital Corporation, a
Delaware corporation and a wholly owned subsidiary of ICP-IV ("IPCC" and,
together with ICP-IV, the "Issuers") promise to pay interest on the principal
amount of this Note at 11 1/4% per annum from July 30, 1996 until maturity and
shall pay the Liquidated Damages payable pursuant to Section 5 of the
Registration Rights Agreement referred to below. The Issuers will pay interest
and Liquidated Damages semi-annually on February 1 and August 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 shall 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 the first Interest Payment Date shall
be February 1, 1997. ICP-IV 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; it 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

      2. METHOD OF PAYMENT. ICP-IV shall 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 January 15 or July 15 next
preceding the Interest Payment Date, even if such Notes are cancelled 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, interest and Liquidated Damages at the
office or agency of ICP-IV maintained for such purpose within or without the
City and State of New York, or, at the option of ICP-IV, 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 written wire transfer
instructions to ICP-IV or the Paying Agent at least 10 Business Days prior to
the applicable payment date. 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.

change any Paying Agent or Registrar without notice to any Holder. ICP-IV or any
of its Subsidiaries may act in any such capacity.

July 30, 1996 (the "Indenture") among the Issuers and the Trustee. The terms of
the Notes include those stated in the Indenture and those made part of the
Indenture by reference to the Trust Indenture Act of 1939, as amended (15 U.S.
Code SectionSection 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. The Notes are obligations of the Issuers limited to $292.0 million in
aggregate principal amount and secured by a portion of the proceeds of the
Offering pursuant to the Pledge Agreement.

      5.  OPTIONAL REDEMPTION.

Public Equity Offering or a Strategic Equity Investment at a redemption price
equal to 111.25% of the principal amount thereof, plus accrued and unpaid
interest and Liquidated Damages, if any, to the date of redemption; provided,
however, that at least 65% in aggregate principal amount of the Notes originally

sinking fund payments with respect to the Notes.

      7.  REPURCHASE AT OPTION OF HOLDER.

      (a) If there is a Change of Control, ICP-IV 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 principal amount thereof plus accrued and any unpaid
interest and Liquidated Damages thereon, if any, to the Change of Control
Payment Date (as hereinafter defined) (the "Change of Control Purchase Price").
Within 30 days of the occurrence of a Change of Control, ICP-IV shall notify the
Trustee in writing of such proposed occurrence and shall make a Change of
Control Offer. Within 50 days following the occurrence of a Change of Control,
ICPIV shall mail a notice to each Holder setting forth the procedures governing
the Change of Control Offer as required by the Indenture.

      (b) If ICP-IV or a Restricted Subsidiary consummates any Asset Sales,
within ten days of each Asset Sale Trigger Date, ICP-IV shall commence an offer

Indenture to purchase the maximum principal amount of Notes 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 Asset Sale Offer Purchase Date 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, ICP-IV (or such Subsidiary) may use such excess for

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 a 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

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

Note selected for redemption, except for the unredeemed portion of any Note
being redeemed in part. Also, it 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, the Pledge Agreement 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, the Pledge Agreement 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,
the Pledge Agreement 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
ICP-IV's obligations to Holders of the Notes in case of a merger or
consolidation, to make any change that would provide any additional rights or
benefits to the Holders of the Notes or that does not adversely affect the legal
rights under the Indenture of any such Holder, or to comply with the
requirements of the SEC in order to effect or maintain the qualification of the
Indenture under the TIA.

      12. DEFAULTS AND REMEDIES. Events of Default include: (i) (a) default in
the payment when due of interest on the Notes on any day on or prior to August
1, 1999, or (b) default for 30 days in the payment when due of interest on the
Notes on any day after August 1, 1999; (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 ICP-IV for 30 days after notice to
ICP-IV by the Trustee or the Holders of at least 25% in principal amount of the
Notes then outstanding to comply with certain other agreements in the Indenture
or the Notes; (iv) default under certain other agreements relating to
Indebtedness of ICP-IV which default results in the acceleration of such
Indebtedness prior to its express maturity; (v) certain final judgments for the
payment of money that remain undischarged for a period of 30 days; and (vi)
certain events of bankruptcy or insolvency with respect to ICP-IV or any of its
Restricted 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 with respect to ICP-IV or any of its
Restricted Subsidiaries, all

                                      A-6
   96
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 interest on, or the principal of, 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 THE ISSUERS. The Trustee, in its individual or
any other capacity, may make loans to, accept deposits from, and perform
services for the Issuers or their Affiliates, and may otherwise deal with the
Issuers or their Affiliates, as if it were not the Trustee.

      14. NO RECOURSE AGAINST OTHERS. No past, present or future director,
officer, employee, incorporator, stockholder or partner 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.

      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 (=

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

      ICP-IV will furnish to any Holder upon written request and without charge
a copy of the Indenture and/or the Registration Rights Agreement. Requests may
