     Section 2.04. Authentication and Delivery of Securities. At any time and
from time to time after the execution and delivery of this Indenture, the Issuer
may deliver Securities of any series executed by the Issuer to the Trustee for
authentication, and the Trustee shall thereupon authenticate and deliver such

by both (a) the chairman of its Board of Directors, or any vice chairman of its

and (subject to Section 5.01) shall be fully protected in relying upon:

     (a) a certified copy of any resolution or resolutions of the Board of
Directors authorizing the action taken pursuant to the resolution or resolutions

                                       11
<PAGE>

          (i) that the form or forms and terms of such Securities have been
     established by or pursuant to a resolution of the Board of Directors or by
     a supplemental indenture as permitted by Section 2.01 and 2.03 in
     conformity with the provisions of this Indenture; and

          (ii) that such Securities, when authenticated and delivered by the
     Trustee and issued by the Issuer in the manner and subject to any
     conditions specified in such Opinion of Counsel, will constitute legal,
     valid and binding obligations of the Issuer enforceable against the Issuer
     in accordance with their terms.

     The Trustee shall have the right to decline to authenticate and deliver any
Securities under this section if the Trustee, being advised by counsel,
determines that such action may not lawfully be taken by the Issuer or if the
Trustee in good faith by its board of directors or board of trustees, executive
committee, or a trust committee of directors or trustees or Responsible Officers
shall determine that such action would expose the Trustee to personal liability.

     If the Issuer shall establish pursuant to Section 2.03 that the Securities
of a series or a portion thereof are to be issued in the form of one or more
Registered Global Securities, then the Issuer shall execute (in accordance with
Section 2.05) and the Trustee shall authenticate and make available for delivery
one or more Registered Global Securities that (i) shall represent and shall be
denominated in an amount equal to the aggregate principal amount of all of the
Securities of such series issued in such form and not yet canceled, (ii) shall
be registered in the name of the Depositary for such Registered Global Security
or Securities or the nominee of such Depositary, (iii) shall be delivered by the
Trustee to such Depositary or its custodian or pursuant to such Depositary's
instructions and (iv) shall bear a legend substantially to the following effect:
"Unless and until it is exchanged in whole or in part for Securities in
definitive registered form, this Security may not be transferred except as a
whole by the Depositary to a nominee of the Depositary or by a nominee of the
Depositary to the Depositary or another nominee of the Depositary or by the
Depositary or any such nominee to a successor Depositary or a nominee of such
successor Depositary."

     Section 2.05. Execution of Securities. The Securities shall be signed on
behalf of the Issuer by the chairman of its Board of Directors or any vice
chairman of its Board of Directors or its president or any vice president or its
treasurer or any assistant treasurer, under its corporate seal and attested by
its secretary or any assistant secretary. Such signatures may be the manual or
facsimile signatures of the present or any future such officers. The seal of the
Issuer may be in the form of a facsimile thereof and may be impressed, affixed,
imprinted or otherwise reproduced on the Securities. Typographical and other
minor errors or defects in any such reproduction of the seal or any such
signature shall not affect the validity or enforceability of any Security that
has been duly authenticated and delivered by the Trustee.

     In case any officer of the Issuer who shall have signed any of the
Securities shall cease to be such officer before the Security so signed shall be
authenticated and delivered by the Trustee or disposed of by the Issuer, such
Security nevertheless may be authenticated and delivered or disposed of as
though the person who signed such Security had not ceased to be such officer of
the Issuer; and any Security may be signed on behalf of the Issuer by such
persons as, at the actual date of the execution of such Security, shall be the
proper officers of the Issuer, although

                                       12
<PAGE>

at the date of the execution and delivery of this Indenture any such person was
not such an officer.

     Section 2.06. Certificate of Authentication. Only such Securities as shall
bear thereon a certificate of authentication substantially in the form
hereinbefore recited, executed by the Trustee by the manual signature of one of
its authorized signatories, shall be entitled to the benefits of this Indenture
or be valid or obligatory for any purpose. Such certificate by the Trustee upon
any Security executed by the Issuer shall be conclusive evidence that the
Security so authenticated has been duly authenticated and delivered hereunder
and that the holder is entitled to the benefits of this Indenture.

     Section 2.07. Denomination and Date of Securities; Payments of Interest.
The Securities shall be issuable as registered securities without coupons and in
denominations as shall be specified as contemplated by Section 2.03. In the
absence of any such specification with respect to the Securities of any series,
the Securities of such series shall be issuable in denominations of $1,000 and
any multiple thereof. The Securities shall be numbered, lettered, or otherwise
distinguished in such manner or in accordance with such plan as the officers of
the Issuer executing the same may determine as evidenced by the execution and
authentication thereof.

     Each Security shall be dated the date of its authentication, shall bear
interest, if any, from the date and shall be payable on the dates, in each case,
which shall be specified as contemplated by Section 2.03.

     The person in whose name any Security of any series is registered at the
close of business on any record date applicable to a particular series with
respect to any interest payment date for such series shall be entitled to
receive the interest, if any, payable on such interest payment date
notwithstanding any transfer or exchange of such Security subsequent to the
record date and prior to such interest payment date, except if and to the extent
the Issuer shall default in the payment of the interest due on such interest
payment date for such series, in which case such defaulted interest shall be
paid to the persons in whose names Outstanding Securities for such series are
registered at the close of business on a subsequent record date (which shall be
not less than five Business Days prior to the date of payment of such defaulted
interest) established by notice given by mail by or on behalf of the Issuer to
the holders of Securities not less than 15 days preceding such subsequent record
date. The term "record date" as used with respect to any interest payment date
(except a date for payment of defaulted interest) shall mean the date specified
as such in the terms of the Securities of any particular series, or, if no such
date is so specified, if such interest payment date is the first day of a
calendar month, the fifteenth day of the next preceding calendar month or, if
such interest payment date is the fifteenth day of a calendar month, the first
day of such calendar month, whether or not such record date is a Business Day.

     Section 2.08. Registration, Transfer and Exchange. The Issuer will keep or
cause to be kept at each office or agency to be maintained for the purpose as
provided in Section 3.02 a register or registers in which, subject to such
reasonable regulations as it may prescribe, it will register, and will register
the transfer of, Securities as in this Article provided. Such register shall be
in written form in the English language or in any other form capable of being
converted into such form within a reasonable time. At all reasonable times such
register or registers shall be open for inspection by the Trustee.

                                       13
<PAGE>

     At the option of the Holder thereof, Registered Securities of any series
(other than a Registered Global Security, except as set forth below) may be
exchanged for a Registered Security or Registered Securities of such series and
tenor having authorized denominations and an equal aggregate principal amount,
upon surrender of such Registered Securities to be exchanged at the agency of
the Issuer that shall be maintained for such purpose in accordance with Section
3.02 and upon payment, if the Issuer shall so require, of the charges
hereinafter provided. If the Securities of any series are issued in both
registered and unregistered form, except as otherwise established pursuant to
Section 2.03, at the option of the Holder thereof, Unregistered Securities of
any series may be exchanged for Registered Securities of such series and tenor
having authorized denominations and an equal aggregate principal amount, upon
surrender of such Unregistered Securities to be exchanged at the agency of the
Issuer that shall be maintained for such purpose in accordance with Section 3.02
and upon payment, if the Issuer shall so require, of the charges hereinafter
provided. At the option of the Holder thereof, if Unregistered Securities of any
series, maturity date, interest rate and original issue date are issued in more
than one authorized denomination, except as otherwise established pursuant to
Section 2.03, such Unregistered Securities may be exchanged for Unregistered
Securities of such series and tenor having authorized denominations and an equal
aggregate principal amount, upon surrender of such Unregistered Securities to be
exchanged at the agency of the Issuer that shall be maintained for such purpose
in accordance with Section 3.02 and upon payment, if the Issuer shall so
require, of the charges hereinafter provided. Registered Securities of any
series may not be exchanged for Unregistered Securities of such series. Whenever
any Securities are so surrendered for exchange, the Issuer shall execute, and
the Trustee shall authenticate and make available for delivery, the Securities
which the Holder making the exchange is entitled to receive.

     All Registered Securities presented for registration of transfer, exchange,
redemption, conversion or payment shall be duly endorsed by, or be accompanied
by a written instrument or instruments of transfer in form satisfactory to the
Issuer and the Trustee duly executed by, the holder or his attorney duly
authorized in writing.

     The Issuer may require payment of a sum sufficient to cover any tax or
other governmental charge that may be imposed in connection with any exchange or
registration of transfer of Securities. No service charge shall be made for any
such transaction.

     Notwithstanding any other provision of this Section 2.08, unless and until
it is exchanged in whole or in part for Securities in definitive registered
form, a Registered Global Security representing all or a portion of the
Securities of a series may not be transferred except as a whole by the
Depositary for such series to a nominee of such Depositary or by a nominee of
such Depositary to such Depositary or another nominee of such Depositary or by
such Depositary or any such nominee to a successor Depositary for such series or
a nominee of such successor Depositary.

     If at any time the Depositary for any Registered Global Securities of any
series notifies the Issuer that it is unwilling or unable to continue as
Depositary for such Registered Global Securities or if at any time the
Depositary for such Registered Global Securities shall no longer be eligible
under applicable law, the Issuer shall appoint a successor Depositary eligible
under applicable law with respect to such Registered Global Securities. If a
successor Depositary eligible under applicable law for such Registered Global
Securities is not appointed by the Issuer within 90 days after the Issuer
receives such notice or becomes aware of such ineligibility, the

                                       14
<PAGE>

Issuer will execute, and the Trustee, upon receipt of the Issuer's order for the
authentication and delivery of definitive Registered Securities of such series
and tenor, will authenticate and make available for delivery Registered
Securities of such series and tenor, in any authorized denominations, in an
aggregate principal amount equal to the principal amount of such Registered
Global Securities, in exchange for such Registered Global Securities.

     The Issuer may at any time and in its sole discretion determine that any
Registered Global Securities of any series shall no longer be maintained in
global form. In such event, or in the event that there shall have occurred and
be continuing an Event of Default with respect to a series of Securities, the
Issuer will, upon the request of any Holder, execute, and the Trustee, upon
receipt of the Issuer's order for the authentication and delivery of definitive
Registered Securities of such series and tenor, will authenticate and make
available for delivery, Registered Securities of such series and tenor in any
authorized denominations, in an aggregate principal amount equal to the
principal amount of such Registered Global Securities, in exchange for such
Registered Global Securities.

     Any time the Registered Securities of any series are not in the form of
Registered Global Securities pursuant to the preceding two paragraphs, the
Issuer agrees to supply the Trustee with a reasonable supply of certificated
Registered Securities without the legend required by Section 2.04 and the
Trustee agrees to hold such Registered Securities in safekeeping until
authenticated and delivered pursuant to the terms of this Indenture.

     If established by the Issuer pursuant to Section 2.03 with respect to any
Registered Global Security, the Depositary for such Registered Global Security
may surrender such Registered Global Security in exchange in whole or in part
for Registered Securities of the same series and tenor in definitive registered
form on such terms as are acceptable to the Issuer and such Depositary.
Thereupon, the Issuer shall execute, and the Trustee shall authenticate and make
available for delivery, without service charge,

          (i) to the Person specified by such Depositary new Registered
     Securities of the same series and tenor, of any authorized denominations as
     requested by such Person, in an aggregate principal amount equal to and in
     exchange for such Person's beneficial interest in the Registered Global
     Security; and

          (ii) to such Depositary a new Registered Global Security in a
     denomination equal to the difference, if any, between the principal amount
     of the surrendered Registered Global Security and the aggregate principal
     amount of Registered Securities authenticated and delivered pursuant to
     clause (i) above.

     Registered Securities issued in exchange for a Registered Global Security
pursuant to this Section 2.08 shall be registered in such names and in such
authorized denominations as the Depositary for such Registered Global Security,
pursuant to instructions from its direct or indirect participants or otherwise,
shall instruct the Trustee or an agent of the Issuer or the Trustee. The Trustee
or such agent shall deliver such Securities to or as directed by the Persons in
whose names such Securities are so registered.

                                       15

     All Securities issued upon any transfer or exchange of Securities shall be
valid obligations of the Issuer, evidencing the same debt, and entitled to the
same benefits under this Indenture, as the Securities surrendered upon such
transfer or exchange.

     Notwithstanding anything herein or in the forms or terms of any Securities
to the contrary, none of the Issuer, the Trustee or any agent of the Issuer or
the Trustee shall be required to exchange any Unregistered Security for a
Registered Security if such exchange would result in adverse Federal income tax
consequences to the Issuer (such as, for example, the inability of the Issuer to
deduct from its income, as computed for Federal income tax purposes, the
interest payable on the Unregistered Securities) under then applicable United
States Federal income tax laws. The Trustee and any such agent shall be entitled
to rely on an Officers' Certificate or an Opinion of Counsel in determining such
result.

     Neither the Registrar nor the Issuer shall be required (i) to issue,
authenticate, register the transfer of or exchange Securities of any series for
a period of 15 days before the mailing of a notice of redemption of such
Securities to be redeemed or (ii) to register the transfer of or exchange any
Security selected for redemption in whole or in part.

     Section 2.09. Mutilated, Defaced, Destroyed, Lost and Stolen Securities. In
case any temporary or definitive Security shall become mutilated or defaced and
shall be surrendered to the Trustee, the Issuer shall execute, and the Trustee
shall authenticate and deliver, a new Security of the same series, bearing a
number not contemporaneously outstanding, in exchange and substitution for the
mutilated or defaced Security. If the Holder of any Security claims that the
Security has been lost, destroyed or wrongfully taken, the Issuer shall execute,
and the Trustee shall authenticate and deliver, a new Security of the same
series, bearing a number not contemporaneously outstanding, in exchange and
substitution for the lost, destroyed or wrongfully taken Security, if the
applicant so requests before the Issuer has notice that the Security has been
acquired by a protected purchaser, and the applicant furnishes to the Issuer and
to the Trustee and any agent of the Issuer or the Trustee such security or
indemnity as may be required by them to indemnify and defend and to save each of
them harmless and the applicant satisfies other reasonable requirements imposed
by the Issuer.

     Upon the issuance of any substitute Security, the Issuer may require the
payment of a sum sufficient to cover any tax or other governmental charge that
may be imposed in relation thereto and any other expenses (including the fees
and expenses of the Trustee and its counsel) connected therewith. In case any
Security which has matured or is about to mature or has been called for
redemption in full shall become mutilated or defaced or be destroyed, lost or
stolen, the Issuer may instead of issuing a substitute Security, pay or
authorize the payment of the same (without surrender thereof except in the case
of a mutilated or defaced Security), if the applicant for such payment shall
furnish to the Issuer and to the Trustee and any agent of the Issuer or the
Trustee such security or indemnity as any of them may require to save each of
them harmless, and, in every case of destruction, loss or wrongful taking, the
applicant shall also furnish to the Issuer and the Trustee and any agent of the
Issuer or the Trustee evidence to their satisfaction of the destruction, loss or
wrongful taking of such Security and of the ownership thereof.

     Every substitute Security of any series issued pursuant to the provisions
of this section by virtue of the fact that any such Security is destroyed, lost
or stolen shall constitute an additional contractual obligation of the Issuer,
whether or not the destroyed, lost or wrongfully taken

                                       16
<PAGE>

Security shall be at any time enforceable by anyone and shall be entitled to all
the benefits of (but shall be subject to all the limitations of rights set forth
in) this Indenture equally and proportionately with any and all other Securities
of such series duly authenticated and delivered hereunder. All Securities shall
be held and owned upon the express condition that, to the extent permitted by
law, the foregoing provisions are exclusive with respect to the replacement or
payment of mutilated, defaced or destroyed, lost or wrongfully taken Securities
and shall preclude any and all other rights or remedies.

     Section 2.10. Cancellation of Securities; Destruction Thereof. All
Securities surrendered for payment, redemption, conversion, registration of
transfer or exchange, or for credit against any payment in respect of a sinking
or analogous fund, if surrendered to the Issuer or any agent of the Issuer or
the Trustee, shall be delivered to the Trustee for cancellation or, if
surrendered to the Trustee, shall be canceled by it; and no Securities shall be
issued in lieu thereof except as expressly permitted by any of the provisions of
this Indenture. The Trustee shall dispose of canceled Securities held by it in
accordance with the record retention policies of the Trustee in effect from time
to time and, if such canceled certificates are destroyed, shall deliver a
certificate of destruction to the Issuer. If the Issuer shall acquire any of the
Securities, such acquisition shall not operate as a redemption or satisfaction
of the indebtedness represented by such Securities unless and until the same are
delivered to the Trustee for cancellation.

     Section 2.11. Temporary Securities. Pending the preparation of definitive
Securities for any series, the Issuer may execute and the Trustee shall
authenticate and deliver temporary Securities for such series (printed,
lithographed, typewritten or otherwise reproduced, in each case in form
satisfactory to the Trustee). Temporary Securities of any series shall be
issuable as registered Securities without coupons, of any authorized
denomination, and substantially in the form of the definitive Securities of such
series but with such omissions, insertions and variations as may be appropriate
for temporary Securities, all as may be determined by the Issuer with the
concurrence of the Trustee. Temporary Securities may contain such reference to
any provisions of this Indenture as may be appropriate. Every temporary Security
shall be executed by the Issuer and be authenticated by the Trustee upon the
same conditions and in substantially the same manner, and with like effect, as
the definitive Securities. Without unreasonable delay the Issuer shall execute
and shall furnish definitive Securities of such series and thereupon temporary
Securities of such series may be surrendered in exchange therefor without charge
at each office or agency to be maintained by the Issuer for that purpose
pursuant to Section 3.02, and the Trustee shall authenticate and deliver in
exchange for such temporary Securities of such series a like aggregate principal
amount of definitive Securities of the same series of authorized denominations.
Until so exchanged, the temporary Securities of any series shall be entitled to
the same benefits under this Indenture as definitive Securities of such series.

     Section 2.12. Computation of Interest. Except as otherwise specified in the
Securities of a series, interest shall be computed on the basis of a 360-day
year of twelve 30-day months.

     Section 2.13. CUSIP Numbers. The Issuer in issuing the Securities 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 Securities or as contained
in any notice of a redemption and that reliance may be placed only on the other
identification numbers printed on the Securities, and any such redemption shall
not be affected

                                       17
<PAGE>

by any defect in or omission of such numbers. The Issuer will notify the Trustee
of any change in the "CUSIP" numbers.

                                   Article 3
          COVENANTS OF THE ISSUER, THE CABLE GUARANTORS AND THE TRUSTEE

     Section 3.01. Payment of Principal and Interest. The Issuer covenants and
agrees for the benefit of each series of Securities that it will duly and
punctually pay or cause to be paid the principal of, and interest on, each of
the Securities of such series at the place or places, at the respective times
and in the manner provided in such Securities. Each installment of interest on
the Securities of any series may be paid by mailing checks for such interest
payable to or upon the written order of the holders of Securities entitled
thereto as they shall appear on the registry books of the Issuer.

     Notwithstanding any provisions of this Indenture and the Securities of any
series to the contrary, if the Issuer and a Holder of any Registered Security so
agree or if expressly provided pursuant to Section 2.03, payments of interest
on, and any portion of the Principal of, such Holder's Registered Security
(other than interest payable at maturity or on any redemption or repayment date
or the final payment of Principal on such Security) shall be made by the paying
agent, upon receipt from the Issuer of immediately available funds by 11:00
a.m., New York City time (or such other time as may be agreed to between the
Issuer and the paying agent) or the Issuer, directly to the Holder of such
Security (by wire transfer of Federal funds or immediately available funds or
otherwise) if the Holder has delivered written instructions to the Trustee 15
days prior to such payment date requesting that such payment will be so made and
designating the bank account to which such payments shall be so made and, in the
case of payments of Principal, surrenders the same to the Trustee in exchange
for a Security or Securities aggregating the same principal amount as the
unredeemed principal amount of the Securities surrendered. The Trustee shall be
entitled to rely on the last instruction delivered by the Holder pursuant to
this Section 3.01 unless a new instruction is delivered 15 days prior to a
payment date. The Issuer will indemnify and hold each of the Trustee and any
paying agent harmless against any loss, liability or expense (including
attorneys' fees and expenses) resulting from any act or omission to act on the
part of the Issuer or any such Holder in connection with any such agreement or
from making any payment in accordance with any such agreement.

     Section 3.02. Offices for Payments, etc. So long as any of the Securities
remain outstanding, the Issuer will maintain in the Borough of Manhattan, The
City of New York an office or agency Error! Bookmark not defined. where the
Securities may be presented for payment, Error! Bookmark not defined. where the
Securities may be presented for registration of transfer and for exchange as in
this Indenture provided, Error! Bookmark not defined. where notices and demands
to or upon the Issuer in respect of the Securities or of this Indenture may be
served and Error! Bookmark not defined. for Securities of each series that is
convertible, where such Securities may be presented for conversion. The Issuer
will give to the Trustee written notice of the location of any such office or
agency and of any change of location thereof. Unless otherwise specified in
accordance with Section 2.03, the Issuer hereby initially designates the
Corporate Trust Office of Trustee as the office to be maintained by it for each
such purpose. In case the Issuer shall fail to so designate or maintain any such
office or agency or shall fail to give such notice of the location

                                       18
<PAGE>

or of any change in the location thereof, presentations and demands may be made
and notices may be served at the Corporate Trust Office.

     Section 3.03. Paying Agents. Whenever the Issuer shall appoint a paying
agent other than the Trustee with respect to the Securities of any series, it
will cause such paying agent to execute and deliver to the Trustee an instrument
in which such agent shall agree with the Trustee, subject to the provisions of
this Section,

     (a) that it will hold all sums received by it as such agent for the payment
of the principal of or interest on the Securities of such series (whether such
sums have been paid to it by the Issuer or by any other obligor on the
Securities of such series) in trust for the benefit of the holders of the
Securities of such series or of the Trustee,

     (b) that it will give the Trustee notice of any failure by the Issuer (or
by any other obligor on the Securities of such series) to make any payment of
the principal of or interest on the Securities of such series when the same
shall be due and payable, and

     (c) that it will pay any such sums so held in trust by it to the Trustee
upon the Trustee's written request at any time during the continuance of the
failure referred to in clause 3.03(b) above.

     The Issuer will, on or prior to each due date of the principal of or
interest on the Securities of such series, deposit with the paying agent a sum
sufficient to pay such principal or interest so becoming due, and (unless such
paying agent is the Trustee) the Issuer will promptly notify the Trustee of any
failure to take such action.

     If the Issuer shall act as its own paying agent with respect to the
Securities of any Series, it will, on or before each due date of the principal
of or interest on the Securities of such series, set aside, segregate and hold
in trust for the benefit of the holders of the Securities of such series a sum
sufficient to pay such principal or interest so becoming due. The Issuer will
promptly notify the Trustee of any failure to take such action.

     Whenever the Issuer shall have one or more paying agents for any series of
Securities, it will, on or before each due date of the principal of or interest
on any Securities of such series, deposit with the paying agent or agents for
the Securities of such series a sum, by 10:00 a.m. New York City time in
immediately available funds on the payment date, sufficient to pay the principal
or interest so becoming due with respect to the Securities of such series, and
(unless such paying agent is the Trustee) the Issuer will promptly notify the
Trustee in writing of any failure so to act.

     Anything in this section to the contrary notwithstanding, the Issuer may at
any time, for the purpose of obtaining a satisfaction and discharge with respect
to one or more or all series of Securities hereunder, or for any other reason,
pay or cause to be paid to the Trustee all sums held in trust for any such
series by the Issuer or any paying agent hereunder, as required by this Section,
such sums to be held by the Trustee upon the trusts herein contained.

         Anything in this section to the contrary notwithstanding, the agreement
to hold sums in trust as provided in this section is subject to the provisions
of Section 9.05.

                                       19
<PAGE>

     Section 3.04. Certificate of the Issuer. Within 120 days after the close of
the fiscal year ended December 31, 2002, and within 120 days after the close of
each fiscal year thereafter, the Issuer will furnish to the Trustee a brief
certificate (which need not comply with Section 10.05) from the principal
executive, financial or accounting officer of the Issuer as to his or her
knowledge of the Issuer's compliance with all conditions and covenants under the
Indenture (such compliance to be determined without regard to any period of
grace or requirement of notice provided under the Indenture).

     At the time such certificate is filed, the Issuer will also file with the
Trustee a letter or statement of the independent accountants who shall have
certified the financial statements of the Issuer for its preceding fiscal year
to the effect that, in making the examination necessary for certification of
such financial statements, they have obtained no knowledge of any default by the
Issuer in the performance or fulfillment of any covenant, agreement or condition
contained in this Indenture, which default remains uncured at the date of such
letter or statement, or, if they shall have obtained knowledge of any such
uncured default, specifying in such letter or statement such default or defaults
and the nature and status thereof, it being understood that such accountants
shall not be liable directly or indirectly for failure to obtain knowledge of
any such default or defaults, and that nothing contained in this Section 3.04
shall be construed to require such accountants to make any investigation beyond
the scope required in connection with such examination.

     Section 3.05. Securityholders Lists. If and so long as the Trustee shall
not be the Security registrar for the Securities of any series, the Issuer will
furnish or cause to be furnished to the Trustee a list in such form as the
Trustee may reasonably require of the names and addresses of the holders of the
Securities of such series pursuant to Section 312 of the Trust Indenture Act of
1939 Error! Bookmark not defined. semi-annually not more than 10 days after each
record date for the payment of interest on such Securities, as hereinabove
specified, as of such record date and on dates to be determined pursuant to
Section 2.03 for non-interest bearing Securities in each year, and Error!
Bookmark not defined. at such other times as the Trustee may request in writing,
within thirty days after receipt by the Issuer of any such request as of a date
not more than 10 days prior to the time such information is furnished.

     Section 3.06 . Reports by the Issuer. The Issuer covenants to:

     (a) file, whether or not required to do so under applicable law, with the
Trustee, within 15 days after the Issuer is required to file the same with the
Commission, copies of the annual reports and of the information, documents, and
other reports which the Issuer may be required to file with the Commission
pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934;
or, if the Issuer is not required to file with the Commission, annual reports,
information, documents and other reports pursuant to either Section 13 or
Section 15(d) of the Securities Exchange Act of 1934, then the Issuer will file
with the Trustee and will file with the Commission, in accordance with rules and
regulations prescribed by the Commission, such of the supplementary and periodic
information, documents and reports required pursuant to Section 13 of the
Securities Exchange Act of 1934 in respect of a security listed and registered
on a national securities exchange as may be prescribed in such rules and
regulations;

     (b) file with the Trustee and the Commission, in accordance with the rules
and regulations prescribed from time to time by the Securities and Exchange
Commission, such

                                       20
<PAGE>

additional information, documents and reports with respect to compliance by the
Issuer with the conditions and covenants provided for in this Indenture as may
be required by such rules and regulations;

     (c) transmit to the Securityholders, in the manner and to the extent
provided in Section 10.04, such summaries of any information, documents and
reports required to be filed with the Trustee pursuant to the provisions of
subdivisions (a) and (b) of this Section 3.06 as may be required by the rules
and regulations of the Commission.

     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 Issuer's
compliance with any of its covenants hereunder (as to which the Trustee is
entitled to rely exclusively on Officers' Certificates).

     Section 3.07. Corporate Existence. So long as any of the Securities remain
unpaid, the Issuer will at all times (except as otherwise provided or permitted
elsewhere in this Indenture) do or cause to be done all things necessary to
preserve and keep in full force and effect its corporate existence.

     Section 3.08. Restrictions on Mergers, Sales and Consolidations. So long as
any of the Securities remain unpaid, the Issuer will not consolidate or merge
with or sell, convey or lease all or substantially all of its property to any
other corporation except as permitted in Article 8 hereof.

     Section 3.09. Further Assurances. From time to time whenever requested by
the Trustee, the Issuer will execute and deliver such further instruments and
assurances and do such further acts as may be reasonably necessary or proper to
carry out more effectually the purposes of this Indenture or to secure the
rights and remedies hereunder of the holders of the Securities of any series.

     Section 3.10. Limitation on Liens.

     Neither the Issuer nor any Cable Guarantor shall create, incur or assume
any Lien (other than any Permitted Lien) on such Person's assets, including the
Capital Stock of its Wholly-Owned Subsidiaries, to secure the payment of
Indebtedness of the Issuer or any Cable Guarantor, unless the Issuer secures the
Outstanding Securities equally and ratably with (or prior to) all Indebtedness
secured by such Lien, so long as such Indebtedness shall be so secured.

     Section 3.11. Limitation on Sale and Leaseback Transactions.

     Neither the Issuer nor any Cable Guarantor shall enter into any Sale and
Leaseback Transaction involving any of such Person's assets, including the
Capital Stock of its Wholly-Owned Subsidiaries.

                                   Article 4
         REMEDIES OF THE TRUSTEE AND SECURITYHOLDERS ON EVENT OF DEFAULT

     Section 4.01. Event of Default Defined; Acceleration of Maturity; Waiver of
Default. "Event of Default" with respect to Securities of any series wherever
used herein, means each one of the following events which shall have occurred
and be continuing (whatever the reason for such Event of Default and whether it
shall be voluntary or involuntary or be effected by operation of law or pursuant
to any judgment, decree or order of any court or any order, rule or regulation
of any administrative or governmental body):

     (a) default by any Obligor in the payment of any installment of interest
upon any of the Securities of such series as and when the same shall become due
and payable, and continuance of such default for a period of 30 days; or

     (b) default by an Obligor in the payment of all or any part of the
principal on any of the Securities of such series as and when the same shall
become due and payable either at maturity, upon redemption, by declaration or
otherwise; or

     (c) default by an Obligor in the performance, or breach by any Obligor, of
any of its covenants or agreements in respect of the Securities of such series
(other than a covenant or agreement in respect of the Securities of such series
a default in whose performance or whose breach is elsewhere in this section
specifically dealt with), and continuance of such default or breach for a period
of 30 consecutive days after there has been given, by registered or certified
mail, to the Issuer by the Trustee or to the Issuer and the Trustee by the
Holders of at least 25% in principal amount of the Outstanding Securities of all
series affected thereby, a written notice specifying such default or breach and
requiring it to be remedied and stating that such notice is a "Notice of
Default" hereunder; or

     (d) a court having jurisdiction in the premises shall enter a decree or
order for relief in respect of any Obligor in an involuntary case under any
applicable bankruptcy, insolvency or other similar law now or hereafter in
effect, or appointing a receiver, liquidator, assignee, custodian, trustee or
sequestrator (or similar official) of any Obligor or for any substantial part of
such party's property and assets or ordering the winding up or liquidation of
any Obligor's affairs, and such decree or order shall remain unstayed and in
effect for a period of 180 consecutive days; or

     (e) any Obligor shall commence a voluntary case under any applicable
bankruptcy, insolvency or other similar law now or hereafter in effect, or
consent to the entry of an order for relief in an involuntary case under any
such law, or consent to the appointment of or taking possession by a receiver,
liquidator, assignee, custodian, trustee or sequestrator (or similar official)
of such party or for any substantial part of such party's property, or make any
general assignment for the benefit of creditors; or

     (f) any Cable Guarantee shall not be (or claimed by any Cable Guarantor not
to be) in full force and effect; or

                                       22
<PAGE>

     (g) any other Event of Default provided in the supplemental indenture or
resolution of the Board of Directors under which such series of Securities is
issued or in the form of Security for such series.

     If an Event of Default described in clauses 4.01(a), 4.01(b), 4.01(c),
4.01(f) or 4.01(g) occurs and is continuing, then, and in each and every such
case, unless the principal of all of the Securities of such series shall have
already become due and payable, either the Trustee or the holders of not less
than 25% in aggregate principal amount of the Securities of any affected series
then Outstanding hereunder (each such series voting as a separate class) by
notice in writing to the Issuer (and to the Trustee if given by
Securityholders), may declare the entire principal (or, if the Securities of
such series are Original Issue Discount Securities, such portion of the
principal amount as may be specified in the terms of such series) of all
Securities of such series and the interest accrued thereon, if any, to be due
and payable immediately, and upon any such declaration the same shall become
immediately due and payable. If an Event of Default described in clauses 4.01(d)
or 4.01(e) occurs and is continuing, then the principal amount of all the
Securities then outstanding and interest accrued thereon, if any, shall be and
become immediately due and payable, without any notice or other action by any
Holder or the Trustee, to the full extent permitted by applicable law.

     The foregoing provisions, however, are subject to the condition that if, at
any time after the principal (or, if the Securities are Original Issue Discount
Securities, such portion of the principal as may be specified in the terms
thereof) of the Securities of any series (or of all the Securities, as the case
may be) shall have been so declared due and payable, and before any judgment or
decree for the payment of the moneys due shall have been obtained or entered as
hereinafter provided, the Issuer shall pay or shall deposit with the Trustee a
sum sufficient to pay all matured installments of interest upon all the
Securities of such series (or of all the Securities, as the case may be) and the
principal of any and all Securities of such series (or of all the Securities, as
the case may be) which shall have become due otherwise than by acceleration
(with interest upon such principal and, to the extent that payment of such
interest is enforceable under applicable law, on overdue installments of
interest, at the same rate as the rate of interest or Yield to Maturity (in the
case of Original Issue Discount Securities) specified in the Securities of such
series (or at the respective rates of interest or Yields to Maturity of all the
Securities, as the case may be) to the date of such payment or deposit) and such
amount as shall be sufficient to cover reasonable compensation to the Trustee,
its agents, attorneys and counsel, and all other expenses and liabilities
incurred, and all advances made, by the Trustee except as a result of negligence
or bad faith, and if any and all Events of Default under the Indenture, other
than the non-payment of the principal of Securities which shall have become due
by acceleration, shall have been cured, waived or otherwise remedied as provided
herein--then and in every such case the holders of a majority in aggregate
principal amount of all the then outstanding Securities of all such series that
have been accelerated, each such series voting as a separate class, by written
notice to the Issuer and to the Trustee, may waive all defaults with respect to
such series (or with respect to all the Securities, as the case may be) and
rescind and annul such declaration and its consequences, but no such waiver or
rescission and annulment shall extend to or shall affect any subsequent default
or shall impair any right consequent thereon.

     For all purposes under this Indenture, if a portion of the principal of any
Original Issue Discount Securities shall have been accelerated and declared due
and payable pursuant to the

                                       23
<PAGE>

provisions hereof, then, from and after such declaration, unless such
declaration has been rescinded and annulled, the principal amount of such
Original Issue Discount Securities shall be deemed, for all purposes hereunder,
to be such portion of the principal thereof as shall be due and payable as a
result of such acceleration, and payment of such portion of the principal
thereof as shall be due and payable as a result of such acceleration, together
with interest, if any, thereon and all other amounts owing thereunder, shall
constitute payment in full of such Original Issue Discount Securities.

     Section 4.02. Collection of Indebtedness by Trustee; Trustee May Prove
Debt. The Issuer covenants that (a) in case default shall be made in the payment
of any installment of interest on any of the Securities of any series when such
interest shall have become due and payable, and such default shall have
continued for a period of 30 days or (b) in case default shall be made in the
payment of all or any part of the principal of any of the Securities of any
series when the same shall have become due and payable, whether upon maturity of
the Securities of such series or upon any redemption or by declaration or
otherwise--then upon demand of the Trustee, the Issuer will pay to the Trustee
for the benefit of the Holders of the Securities of such series the whole amount
that then shall have become due and payable on all Securities of such series for
principal or interest, as the case may be (with interest to the date of such
payment upon the overdue principal and, to the extent that payment of such
interest is enforceable under applicable law, on overdue installments of
interest at the same rate as the rate of interest or Yield to Maturity (in the
case of Original Issue Discount Securities) specified in the Securities of such
series); and in addition thereto, such further amount as shall be sufficient to
cover the costs and expenses of collection, including reasonable compensation to
the Trustee and each predecessor Trustee, their respective agents and counsel,
and any expenses and liabilities incurred, and all advances made, by the Trustee
and each predecessor Trustee except as a result of its negligence or bad faith.

     Until such demand is made by the Trustee, the Issuer may pay the principal
of and interest on the Securities of any series to the registered holders,
whether or not the principal of and interest on the Securities of such series be
overdue.

     In case the Issuer shall fail forthwith to pay such amounts upon such
demand, the Trustee, in its own name and as trustee of an express trust, shall
be entitled and empowered to institute any action or proceedings at law or in
equity for the collection of the sums so due and unpaid, and may prosecute any
such action or proceedings to judgment or final decree, and may enforce any such
judgment or final decree against the Issuer or other obligor upon such
Securities and collect in the manner provided by law out of the property of the
Issuer or other obligor upon such Securities, wherever situated, the moneys
adjudged or decreed to be payable.

     In case there shall be pending proceedings relative to the Issuer or any
other obligor upon the Securities under Title 11 of the United States Code or
any other applicable Federal or state bankruptcy, insolvency or other similar
law, or in case a receiver, assignee or trustee in bankruptcy or reorganization,
liquidator, sequestrator or similar official shall have been appointed for or
taken possession of the Issuer or its property or such other obligor, or in case
of any other comparable judicial proceedings relative to the Issuer or other
obligor upon the Securities of any series, or to the creditors or property of
the Issuer or such other obligor, the Trustee, irrespective of whether the
principal of any Securities shall then be due and payable as therein expressed
or by declaration or otherwise and irrespective of whether the Trustee shall

                                       24
<PAGE>

have made any demand pursuant to the provisions of this Section, shall be
entitled and empowered, by intervention in such proceedings or otherwise:

     (a) to file and prove a claim or claims for the whole amount of principal
and interest (or, if the Securities of any series are Original Issue Discount
Securities, such portion of the principal amount as may be specified in the
terms of such series) owing and unpaid in respect of the Securities of any
series, and to file such other papers or documents as may be necessary or
advisable in order to have the claims of the Trustee (including any claim for
reasonable compensation to the Trustee and each predecessor Trustee, and their
respective agents, attorneys and counsel, and for reimbursement of all expenses
and liabilities incurred, and all advances made, by the Trustee and each
predecessor Trustee, except as a result of negligence or bad faith) and of the
Securityholders allowed in any judicial proceedings relative to the Issuer or
other obligor upon the Securities of any series, or to the creditors or property
of the Issuer or such other obligor,

     (b) unless prohibited by applicable law and regulations, to vote on behalf
of the holders of the Securities of any series in any election of a trustee or a
standby trustee in arrangement, reorganization, liquidation or other bankruptcy
or insolvency proceedings or person performing similar functions in comparable
proceedings, and

     (c) to collect and receive any moneys or other property payable or
deliverable on any such claims, and to distribute all amounts received with
respect to the claims of the Securityholders and of the Trustee on their behalf;
and any trustee, receiver, or liquidator, custodian or other similar official is
hereby authorized by each of the Securityholders to make payments to the
Trustee, and, in the event that the Trustee shall consent to the making of
payments directly to the Securityholders, to pay to the Trustee such amounts as
shall be sufficient to cover reasonable compensation to the Trustee, each
predecessor Trustee and their respective agents, attorneys and counsel, and all
other expenses and liabilities incurred, and all advances made, by the Trustee
and each predecessor Trustee except as a result of negligence or bad faith and
all other amounts due to the Trustee or any predecessor Trustee pursuant to
Section 5.06.

     Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or vote for or accept or adopt on behalf of any
Securityholder any plan or reorganization, arrangement, adjustment or
composition affecting the Securities of any series or the rights of any Holder
thereof, or to authorize the Trustee to vote in respect of the claim of any
Securityholder in any such proceeding except, as aforesaid, to vote for the
election of a trustee in bankruptcy or similar person.

     All rights of action and of asserting claims under this Indenture, or under
any of the Securities, may be enforced by the Trustee without the possession of
any of the Securities or the production thereof on any trial or other
proceedings relative thereto, and any such action or proceedings instituted by
the Trustee shall be brought in its own name as trustee of an express trust, and
any recovery of judgment, subject to the payment of the expenses, disbursements
and compensation of the Trustee, each predecessor Trustee and their respective
agents and attorneys, shall be for the ratable benefit of the holders of the
Securities in respect of which such action was taken.

                                       25
<PAGE>

     In any proceedings brought by the Trustee (and also any proceedings
involving the interpretation of any provision of this Indenture to which the
Trustee shall be a party) the Trustee shall be held to represent all the holders
of the Securities in respect to which such action was taken, and it shall not be
necessary to make any holders of such Securities parties to any such
proceedings.

     Section 4.03. Application of Proceeds. Any moneys collected by the Trustee
pursuant to this Article in respect of any series shall be applied in the
following order at the date or dates fixed by the Trustee and, in case of the
distribution of such moneys on account of principal or interest, upon
presentation of the several Securities in respect of which monies have been
collected and stamping (or otherwise noting) thereon the payment, or issuing
Securities of such series in reduced principal amounts in exchange for the
presented Securities of like series if only partially paid, or upon surrender
thereof if fully paid:

          FIRST: To the payment of costs and expenses applicable to such series
     in respect of which monies have been collected, including reasonable
     compensation to the Trustee and each predecessor Trustee and their
     respective agents and attorneys and of all expenses and liabilities
     incurred, and all advances made, by the Trustee and each predecessor
     Trustee except as a result of negligence or bad faith, and all other
     amounts due to the Trustee or any predecessor Trustee pursuant to Section
     5.06;

          SECOND: In case the principal of the Securities of such series in
     respect of which moneys have been collected shall not have become and be
     then due and payable, to the payment of interest on the Securities of such
     series in default in the order of the maturity of the installments of such
     interest, with interest (to the extent that such interest has been
     collected by the Trustee) upon the overdue installments of interest at the
     same rate as the rate of interest or Yield to Maturity (in the case of
     Original Issue Discount Securities) specified in such Securities, such
     payments to be made ratably to the persons entitled thereto, without
     discrimination or preference;

          THIRD: In case the principal of the Securities of such series in
     respect of which moneys have been collected shall have become and shall be
     then due and payable, to the payment of the whole amount then owing and
     unpaid upon all the Securities of such series for principal and interest,
     with interest upon the overdue principal, and (to the extent that such
     interest has been collected by the Trustee) upon overdue installments of
     interest at the same rate as the rate of interest or Yield to Maturity (in
     the case of Original Issue Discount Securities) specified in the Securities
     of such series; and in case such moneys shall be insufficient to pay in
     full the whole amount so due and unpaid upon the Securities of such series,
     then to the payment of such principal and interest or yield to maturity,
     without preference or priority of principal over interest or yield to
     maturity, or of interest or yield to maturity over principal, or of any
     installment of interest over any other installment of interest, or of any
     Security of such series over any other Security of such series, ratably to
     the aggregate of such principal and accrued and unpaid interest or yield to
     maturity; and

          FOURTH: To the payment of the remainder, if any, to the Issuer or any
     other person lawfully entitled thereto.

                                       26

     Section 4.04. Suits for Enforcement. In case an Event of Default has
occurred, has not been waived and is continuing, the Trustee may proceed to
protect and enforce the rights vested in it by this Indenture, either at law or
in equity or in bankruptcy or otherwise, whether for the specific enforcement of
any covenant or agreement contained in this Indenture or in aid of the exercise
of any power granted in this Indenture or to enforce any other legal or
equitable right vested in the Trustee by this Indenture or by law.

     Section 4.05. Restoration of Rights on Abandonment of Proceedings. In case
the Trustee shall have proceeded to enforce any right under this Indenture and
such proceedings shall have been discontinued or abandoned for any reason, or
shall have been determined adversely to the Trustee, then and in every such case
the Issuer, any Cable Guarantors and the Trustee shall be restored respectively
to their former positions and rights hereunder, and all rights, remedies and
powers of the Issuer, any Cable Guarantors, the Trustee and the Securityholders
shall continue as though no such proceedings had been taken.

     Section 4.06. Limitations on Suits by Securityholder. No holder of any
Security of any series shall have any right by virtue or by availing of any
provision of this Indenture to institute any action or proceeding at law or in
equity or in bankruptcy or otherwise upon or under or with respect to this
Indenture, or for the appointment of a trustee, receiver, liquidator, custodian
or other similar official or for any other remedy hereunder, unless such holder
previously shall have given to the Trustee written notice of an Event of Default
and of the continuance thereof, as hereinbefore provided, and unless also the
holders of not less than 25% in aggregate principal amount of the Securities of
such series then outstanding shall have made written request upon the Trustee to
institute such action or proceedings in respect of such Event of Default in its
own name as trustee hereunder and shall have offered to the Trustee indemnity
satisfactory to the Trustee against the costs, expenses and liabilities to be
incurred therein or thereby and the Trustee for 60 days after its receipt of
such notice, request and offer of indemnity shall have failed to institute any
such action or proceeding and no direction inconsistent with such written
request shall have been given to the Trustee pursuant to Section 4.09; it being
understood and intended, and being expressly covenanted by the Holder of every
Security with every other Holder and the Trustee, that no one or more Holders of
Securities of any series shall have any right in any manner whatever by virtue
or by availing of any provision of this Indenture to affect, disturb or
prejudice the rights of any other such Holder of Securities, or to obtain or
seek to obtain priority over or preference to any other such Holder or to
enforce any right under this Indenture, except in the manner herein provided and
for the equal, ratable and common benefit of all Holders of Securities of the
applicable series. For the protection and enforcement of the provisions of this
Section, each and every Securityholder and the Trustee shall be entitled to such
relief as can be given either at law or in equity.

     Section 4.07. Unconditional Right of Securityholders to Institute Certain
Suits. Notwithstanding any other provision in this Indenture and any provision
of any Security, the right of any Holder of any Security to receive payment of
the principal of, premium, if any, or interest on such Security on or after the
respective due dates expressed in such Security, or to institute suit for the
enforcement of any such payment on or after such respective dates, shall not be
impaired or affected without the consent of such Holder.

     Section 4.08. Powers and Remedies Cumulative; Delay or Omission Not Waiver
of Default. Except as provided in Section 4.06, no right or remedy herein
conferred upon or

                                       27
<PAGE>

reserved to the Trustee or to the Securityholders is intended to be exclusive of
any other right or remedy, and every right and remedy shall, to the extent
permitted by law, be cumulative and in addition to every other right and remedy
given hereunder or now or hereafter existing at law or in equity or otherwise.
The assertion or employment of any right or remedy hereunder, or otherwise,
shall not prevent the concurrent assertion or employment of any other
appropriate right or remedy.

     No delay or omission of the Trustee or of any Securityholder to exercise
any right or power accruing upon any Event of Default occurring and continuing
as aforesaid shall impair any such right or power or shall be construed to be a
waiver of any such Event of Default or an acquiescence therein; and, subject to
Section 4.06, every power and remedy given by this Indenture or by law to the
Trustee or to the Securityholders may be exercised from time to time, and as
often as shall be deemed expedient, by the Trustee or by the Securityholders.

     Section 4.09. Control by Securityholders. The Holders of a majority in
aggregate principal amount of the Securities of each series affected (with each
series voting as a separate class) at the time outstanding shall have the right
to direct the time, method, and place of conducting any proceeding for any
remedy available to the Trustee, or exercising any trust or power conferred on
the Trustee with respect to the Securities of such series by this Indenture;
provided that such direction shall not be otherwise than in accordance with law
and the provisions of this Indenture and provided further that (subject to the
provisions of Section 5.01) the Trustee shall have the right to decline to
follow any such direction if the Trustee, being advised by counsel, shall
determine that the action or proceeding so directed may not lawfully be taken or
if the Trustee in good faith by its board of directors, the executive committee,
or a trust committee of directors or Responsible Officers of the Trustee shall
determine that the action or proceedings so directed would involve the Trustee
in personal liability or if the Trustee in good faith shall so determine that
the actions or forbearances specified in or pursuant to such direction would be
unduly prejudicial to the interests of Holders of the Securities of all series
so affected not joining in the giving of said direction.

     Nothing in this Indenture shall impair the right of the Trustee to take any
action which is not inconsistent with such direction or directions by
Securityholders.

     Section 4.10. Waiver of Past Defaults. Prior to a declaration of the
acceleration of the maturity of the Securities of any series as provided in
Section 4.01, the Holders of a majority in aggregate principal amount of the
Securities of such series at the time Outstanding (each such series voting as a
separate class) may on behalf of the Holders of all the Securities of such
series waive an existing default or Event of Default, except a default in the
payment of Principal of or interest on any Security as specified in clauses (a)
or (b) of Section 4.01 or in respect of a covenant or provision hereof which
cannot be modified or amended without the consent of each Holder affected as
provided in Section 7.02. In the case of any such waiver, the Issuer, the
Trustee and the Holders of the Securities of each series affected shall be
restored to their former positions and rights hereunder, respectively.

     Upon any such waiver, such default shall cease to exist and be deemed to
have been cured and not to have occurred, and any Event of Default arising
therefrom shall be deemed to have been cured, and not to have occurred for every
purpose of this Indenture; but no such

                                       28
<PAGE>

waiver shall extend to any subsequent or other default or Event of Default or
impair any right consequent thereon.

     Section 4.11. Trustee to Give Notice of Default, But May Withhold in
Certain Circumstances. The Trustee shall give to the Securityholders of any
series, as the names and addresses of such Holders appear on the registry books,
notice by mail of all defaults known to Responsible Officers of the Trustee
which have occurred with respect to such series, such notice to be transmitted
within 90 days after the occurrence thereof, unless such defaults shall have
been cured before the giving of such notice (the term "default" or "defaults"
for the purposes of this section being hereby defined to mean any event or
condition which is, or with notice or lapse of time or both would become, an
Event of Default); provided that, except in the case of default in the payment
of the principal of or interest on any of the Securities of such series, or in
the payment of any sinking or purchase fund installment with respect to the
Securities of such series, the Trustee shall be protected in withholding such
notice if and so long as the board of directors, the executive committee, or a
trust committee of directors or trustees and/or Responsible Officers of the
Trustee in good faith determines that the withholding of such notice is in the
interests of the Securityholders of such series.

     Section 4.12. Right of Court to Require Filing of Undertaking to Pay Costs.
All parties to this Indenture agree, and each Holder of any Security by his
acceptance thereof shall be deemed to have agreed, that any court may in its
discretion require, in any suit for the enforcement of any right or remedy under
this Indenture or in any suit against the Trustee for any action taken, suffered
or omitted by it as Trustee, the filing by any party litigant in such suit of an
undertaking to pay the costs of such suit, and that such court may in its
discretion assess reasonable costs, including reasonable attorneys' fees and
expenses, against any party litigant in such suit, having due regard to the
merits and good faith of the claims or defenses made by such party litigant; but
the provisions of this section shall not apply to any suit instituted by the
Trustee, to any suit instituted by any Securityholder or group of
Securityholders of any series holding in the aggregate more than 10% in
aggregate principal amount of the Securities of such series, or, to any suit
instituted by a Holder pursuant to Section 4.07.

                                   Article 5
                             CONCERNING THE TRUSTEE

     Section 5.01. Duties and Responsibilities of the Trustee; During Default;
Prior to Default. With respect to the Holders of any series of Securities issued
hereunder, the Trustee, prior to the occurrence of an Event of Default with
respect to the Securities of a particular series and after the curing or waiving
of all Events of Default which may have occurred with respect to such series,
undertakes to perform such duties and only such duties as are specifically set
forth in this Indenture. In case an Event of Default with respect to the
Securities of a series has occurred (which has not been cured or waived) 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 their exercise, as a
prudent person would exercise or use under the circumstances in the conduct of
such person's own affairs.

                                       29

     (a) Prior to the occurrence of an Event of Default with respect to the
Securities of any series and after the curing or waiving of all such Events of
Default with respect to such series which may have occurred:

          (1) the duties and obligations of the Trustee with respect to the
     Securities of any Series shall be determined solely by the express
     provisions of this Indenture, and the Trustee shall not be liable except
     for the performance of such duties and obligations as are specifically set
     forth in this Indenture, and no implied covenants or obligations shall be
     read into this Indenture against the Trustee; and

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

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

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

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

          (3) the Trustee shall not be liable with respect to any action taken,
     suffered or omitted to be taken by it in good faith in accordance with the
     direction of the holders relating to the time, method and place of
     conducting any proceeding for any remedy available to the Trustee, or
     exercising any trust or power conferred upon the Trustee, under this
     Indenture.

     None of the provisions contained in this Indenture shall require the
Trustee to expend or risk its own funds or otherwise incur personal financial
liability in the performance of any of its duties or in the exercise of any of
its rights or powers, if there shall be reasonable ground for believing that the
repayment of such funds or adequate indemnity against such liability is not
reasonably assured to it.

     The provisions of this Section 5.01 are in furtherance of and subject to
Sections 315 and 316 of the Trust Indenture Act of 1939.

                                       30
<PAGE>

     Whether or not therein expressly provided, every provision of this
Indenture relating to the conduct or affecting the liability of or affording
protection to the Trustee shall be subject to the provisions of this Section
5.01.

     Section 5.02. Certain Rights of the Trustee. In furtherance of and subject
to the Trust Indenture Act of 1939, and subject to Section 5.01:

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

     (b) any request, direction, order or demand of the Issuer mentioned herein
shall be sufficiently evidenced by an Officers' Certificate (unless other
evidence in respect thereof be herein specifically prescribed); and any
resolution of the Board of Directors may be evidenced to the Trustee by a copy
thereof certified by the secretary or an assistant secretary of the Issuer;

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

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

     (e) the Trustee shall not be liable for any action taken or omitted by it
in good faith and believed by it to be authorized or within the discretion,
rights or powers conferred upon it by this Indenture;

     (f) prior to the occurrence of an Event of Default hereunder and after the
curing or waiving of all Events of Default, the Trustee shall not be bound to
make any investigation into the facts or matters stated in any resolution,
certificate, statement, instrument, opinion, report, notice, request, consent,
order, approval, appraisal, bond, debenture, note, coupon, security, or other
paper or document unless requested in writing so to do by the holders of not
less than a majority in aggregate principal amount of the Securities of all
series affected then outstanding; provided that, if the payment within a
reasonable time to the Trustee of the costs, expenses or liabilities likely to
be incurred by it in the making of such investigation is, in the opinion of the
Trustee, not reasonably assured to the Trustee by the security afforded to it by
the terms of this Indenture, the Trustee may require indemnity satisfactory to
it against such expenses or liabilities as a condition to proceeding; the
reasonable expenses of every such investigation shall be paid by the Issuer or,
if paid by the Trustee or any predecessor trustee, shall be repaid by the Issuer
upon demand;

                                       31
<PAGE>

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

     (h) the Trustee shall not be liable for any action taken, suffered or
omitted in good faith and believed by it to be authorized or within the
discretion, rights or powers conferred upon it by this Indenture;

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

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

     (k) the Trustee may request that the Issuer deliver an Officers'
Certificate setting forth the names of individuals and/or titles of officers
authorized at such time to take specified actions pursuant to this Indenture,
which Officers' Certificate may be signed by any person authorized to sign an
Officers' Certificate, including any person specified as so authorized in any
such certificate previously delivered and not superseded.

     Section 5.03. Trustee Not Responsible for Recitals, Disposition of
Securities or Application of Proceeds Thereof. The recitals contained herein and
in the Securities, except the Trustee's certificates of authentication, shall be
taken as the statements of the Issuer, and the Trustee assumes no responsibility
for the correctness of the same. The Trustee makes no representation as to the
validity or sufficiency of this Indenture, the Securities or the Cable
Guarantees. The Trustee shall not be accountable for the use or application by
the Issuer of any of the Securities or of the proceeds thereof.

     Section 5.04. Trustee and Agents May Hold Securities; Collections, etc. The
Trustee or any agent of the Issuer or the Trustee, in its individual or any
other capacity, may become the owner or pledgee of Securities with the same
rights it would have if it were not the Trustee or such agent and may otherwise
deal with the Issuer and receive, collect, hold and retain collections from the
Issuer with the same rights it would have if it were not the Trustee or such
agent.

     Section 5.05. Moneys Held by Trustee. All moneys received by the Trustee in
trust hereunder need not be segregated from other funds except to the extent
required by mandatory provisions of law. Neither the Trustee nor any agent of
the Issuer or the Trustee shall be under any liability for interest on any
moneys received by it hereunder.

     Section 5.06. Compensation and Indemnification of Trustee and Its Prior
Claim. The Issuer covenants and agrees to pay to the Trustee from time to time,
and the Trustee shall be entitled to, such compensation as shall be agreed in
writing from time to time by the Issuer and

                                       32
<PAGE>

the Trustee (which shall not be limited by any provision of law in regard to the
compensation of a trustee of an express trust) and the Issuer covenants and
agrees to pay or reimburse the Trustee and each predecessor Trustee upon its
request for all reasonable expenses, disbursements and advances incurred or made
by or on behalf of it in accordance with any of the provisions of this Indenture
(including the reasonable compensation and the expenses and disbursements of its
counsel and of all agents and other persons not regularly in its employ) except
to the extent any such expense, disbursement or advance may arise from its
negligence or bad faith. The Issuer also covenants and agrees to indemnify the
Trustee and each predecessor Trustee for, and to hold it harmless against, any
loss, liability or expense arising out of or in connection with the acceptance
or administration of this Indenture or the trusts hereunder and the performance
of its duties hereunder, including the costs and expenses of defending itself
against or investigating any claim of liability (whether asserted by the Issuer,
a Cable Guarantor, a Holder or any other Person) in the premises, except to the
extent such loss, liability or expense is due to the negligence or bad faith of
the Trustee or such predecessor Trustee. The obligations of the Issuer under
this section to compensate and indemnify the Trustee and each predecessor
Trustee and to pay or reimburse the Trustee and each predecessor Trustee for
expenses, disbursements and advances shall constitute additional indebtedness
hereunder and shall survive the satisfaction and discharge of this Indenture or
the resignation or removal of the Trustee. Such additional indebtedness shall be
a senior claim and lien to that of the Securities upon all property and funds
held or collected by the Trustee as such, except funds held in trust for the
benefit of the holders of particular Securities, and the Securities are hereby
subordinated to such senior claim. The parties agree that if the Trustee renders
services following an Event of Default under Section 4.01(d) or (e),
compensation for such services is intended to constitute administrative expense
under any bankruptcy law.

     Section 5.07. Right of Trustee to Rely on Officers' Certificate, etc.
Subject to Sections 5.01 and 5.02, whenever in the administration of the trusts
of this Indenture the Trustee shall deem it necessary or desirable that a matter
be proved or established prior to taking or suffering or omitting any action
hereunder, such matter (unless other evidence in respect thereof be herein
specifically prescribed) may, in the absence of negligence or bad faith on the
part of the Trustee, be deemed to be conclusively proved and established by an
Officers' Certificate delivered to the Trustee, and such certificate, in the
absence of negligence or bad faith on the part of the Trustee, shall be full
warrant to the Trustee for any action taken, suffered or omitted by it under the
provisions of this Indenture upon the faith thereof.

     Section 5.08. Persons Eligible for Appointment as Trustee. The Trustee for
each series of Securities hereunder shall at all times be a corporation which is
eligible in accordance with the provisions of Section 310(a) of the Trust
Indenture Act of 1939 and which has, or is a Wholly-Owned Subsidiary, directly
or indirectly of a bank holding company which has, a combined capital and
surplus of $50,000,000. If such corporation or holding company publishes reports
of condition at least annually, pursuant to law or to the requirements of a
Federal, State or District of Columbia supervising or examining authority, then
for the purposes of this Section, the combined capital and surplus of such
corporation or holding company shall be deemed to be its combined capital and
surplus as set forth in its most recent report of condition so published.

     Section 5.09. Resignation and Removal; Appointment of Successor Trustee.
Error! Bookmark not defined. The Trustee, or any trustee or trustees hereafter
appointed, may at any time resign with respect to one

                                       33
<PAGE>

or more or all series of Securities by giving written notice of resignation to
the Issuer. Upon receiving such notice of resignation, the Issuer shall promptly
appoint a successor trustee or trustees with respect to the applicable series by
written instrument in duplicate, executed by authority of the Board of
Directors, one copy of which instrument shall be delivered to the resigning
Trustee and one copy to the successor trustee or trustees. If no successor
Trustee shall have been so appointed with respect to any series and have
accepted appointment within 30 days after the mailing of such notice of
resignation, the resigning Trustee may petition, at the expense of the Issuer,
any court of competent jurisdiction for the appointment of a successor Trustee,
or any Securityholder who has been a bona fide Holder of a Security or
Securities of the applicable series for at least six months may, subject to the
provisions of Section 4.12, on behalf of himself and all others similarly
situated, petition any such court for the appointment of a successor Trustee.
Such court may thereupon, after such notice, if any, as it may deem proper and
prescribe, appoint a successor Trustee.

     (b) In case at any time any of the following shall occur:

          (i) the Trustee shall fail to comply with the provisions of Section
     310(b) of the Trust Indenture Act of 1939 with respect to any series of
     Securities after written request therefor by the Issuer or by any
     Securityholder who has been a bona fide Holder of a Security or Securities
     of such series for at least six months; or

          (ii) the Trustee shall cease to be eligible in accordance with the
     provisions of Section 310(a) of the Trust Indenture Act of 1939 and shall
     fail to resign after written request therefor by the Issuer or by any
     Securityholder; or

          (iii) the Trustee shall become incapable of acting with respect to any
     series of Securities, or shall be adjudged a bankrupt or insolvent, or a
     receiver or liquidator of the Trustee or of its property shall be
     appointed, or any public officer shall take charge or control of the
     Trustee or of its property or affairs for the purpose of rehabilitation,
     conservation or liquidation;

then, in any such case, the Issuer may remove the Trustee with respect to the
applicable series of Securities and appoint a successor trustee for such series
by written instrument, in duplicate, executed by order of the Board of Directors
of the Issuer, one copy of which instrument shall be delivered to the Trustee so
removed and one copy to the successor Trustee, or, subject to Section 315(e) of
the Trust Indenture Act of 1939, any Securityholder who has been a bona fide
Holder of a Security or Securities of such series for at least six months may on
behalf of himself and all others similarly situated, petition any court of
competent jurisdiction for the removal of the Trustee and the appointment of a
successor trustee with respect to such series. Such court may thereupon, after
such notice, if any, as it may deem proper and prescribe, remove the Trustee and
appoint a successor trustee.

     (c) The Holders of a majority in aggregate principal amount of the
Securities of each series at the time outstanding may at any time remove the
Trustee with respect to Securities of such series and appoint a successor
Trustee with respect to the Securities of such series by delivering to the
Trustee so removed, to the successor Trustee so appointed and to the Issuer the
evidence provided in Section 6.01 of the action in that regard taken by the
Securityholders.

                                       34

     (d) Any resignation or removal of the Trustee with respect to any series
and any appointment of a successor trustee with respect to such series pursuant
to any of the provisions of this Section 5.09 shall become effective upon
acceptance of appointment by the successor trustee as provided in Section 5.10.

     Section 5.10. Acceptance of Appointment by Successor. Any successor Trustee
appointed as provided in Section 5.09 shall execute and deliver to the Issuer
and to its predecessor Trustee an instrument accepting such appointment
hereunder, and thereupon the resignation or removal of the predecessor Trustee
with respect to all or any applicable series shall become effective and such
successor Trustee, without any further act, deed or conveyance, shall become
vested with all rights, powers, duties and obligations with respect to such
series of its predecessor hereunder, with like effect as if originally named as
Trustee for such series hereunder; but, nevertheless, on the written request of
the Issuer or of the successor Trustee, upon payment of its charges then unpaid,
the Trustee ceasing to act shall, subject to Section 5.06, pay over to the
successor Trustee all moneys at the time held by it hereunder and shall execute
and deliver an instrument transferring to such successor Trustee all such
rights, powers, duties and obligations. Upon request of any such successor
Trustee, the Issuer shall execute any and all instruments in writing for more
fully and certainly vesting in and confirming to such successor Trustee all such
rights and powers. Any Trustee ceasing to act shall, nevertheless, retain a
prior claim upon all property or funds held or collected by such Trustee to
secure any amounts then due it pursuant to the provisions of Section 5.06.

     If a successor Trustee is appointed with respect to the Securities of one
or more (but not all) series, the Issuer, the predecessor Trustee and each
successor Trustee with respect to the Securities of any applicable series shall
execute and deliver an indenture supplemental hereto which shall contain such
provisions as shall be deemed necessary or desirable to confirm that all the
rights, powers, trusts and duties of the predecessor Trustee with respect to the
Securities of any series as to which the predecessor Trustee is not retiring
shall continue to be vested in the predecessor Trustee, and shall add to or
change any of the provisions of this Indenture as shall be necessary to provide
for or facilitate the administration of the trusts hereunder by more than one
Trustee, it being understood that nothing herein or in such supplemental
indenture shall constitute such Trustees co-trustees of the same trust and that
each such Trustee shall be Trustee of a trust or trusts under separate
indentures.

     Upon acceptance of appointment by any successor Trustee as provided in this
Section 5.10, the Issuer shall mail notice thereof by first-class mail to the
Holders of Securities of any series for which such successor Trustee is acting
as Trustee at their last addresses as they shall appear in the Security
register. If the acceptance of appointment is substantially contemporaneous with
the resignation, then the notice called for by the preceding sentence may be
combined with the notice called for by Section 5.09. If the Issuer fails to mail
such notice within ten days after acceptance of appointment by the successor
Trustee, the successor Trustee shall cause such notice to be mailed at the
expense of the Issuer.

     Section 5.11. Merger, Conversion, Consolidation or Succession to Business
of Trustee. Any corporation into which the Trustee may be merged or converted or
with which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any
corporation succeeding to all or substantially all the corporate trust business
of the Trustee, shall be the successor of the Trustee hereunder, provided that
such

                                       35
<PAGE>

corporation shall be eligible under the provisions of Section 5.08, without the
execution or filing of any paper or any further act on the part of any of the
parties hereto, anything herein to the contrary notwithstanding.

     In case at the time such successor to the Trustee shall succeed to the
trusts created by this Indenture any of the Securities of any series shall have
been authenticated but not delivered, any such successor to the Trustee may
adopt the certificate of authentication of any predecessor Trustee and deliver
such Securities so authenticated; and, in case at that time any of the
Securities of any series shall not have been authenticated, any successor to the
Trustee may authenticate such Securities either in the name of any predecessor
hereunder or in the name of the successor Trustee; and in all such cases such
certificate shall have the full force which it is anywhere in the Securities of
such series or in this Indenture provided that the certificate of the Trustee
shall have; provided, that the right to adopt the certificate of authentication
of any predecessor Trustee or to authenticate Securities of any series in the
name of any predecessor Trustee shall apply only to its successor or successors
by merger, conversion or consolidation.

     Section 5.12. Reports to the Trustee. The Trustee shall transmit to Holders
such reports concerning the Trustee and its actions under this Indenture as may
be required pursuant to the Trust Indenture Act at the times and in the manner
provided pursuant thereto. If required by Section 313(a) of the Trust Indenture
Act, the Trustee shall, within sixty days after each May 15 following the date
of the initial issuance of Securities under this Indenture deliver to Holders a
brief report, dated as of such May 15, which complies with the provisions of
such Section 313(a).

     A copy of each such report shall, at the time of such transmission to
Holders, be filed by the Trustee with each stock exchange, if any, upon which
the Securities are listed, with the Commission and with the Issuer. The Issuer
will promptly notify the Trustee when the Securities are listed on any stock
exchange and of any delisting thereof.

                                   Article 6
                         CONCERNING THE SECURITYHOLDERS

     Section 6.01. Evidence of Action Taken by Securityholders. Any request,
demand, authorization, direction, notice, consent, waiver or other action
provided by this Indenture to be given or taken by a specified percentage in
principal amount of the Securityholders of any or all series may be embodied in
and evidenced by one or more instruments of substantially similar tenor signed
by such specified percentage of Securityholders in person or by agent duly
appointed in writing; and, except as herein otherwise expressly provided, such
action shall become effective when such instrument or instruments are delivered
to the Trustee. Proof of execution of any instrument or of a writing appointing
any such agent shall be sufficient for any purpose of this Indenture and
(subject to Sections 5.01 and 5.02) conclusive in favor of the Trustee and the
Issuer, if made in the manner provided in this Article.

     Section 6.02. Proof of Execution of Instruments and of Holding of
Securities; Record Date. Subject to Sections 5.01 and 5.02, the execution of any
instrument by a Securityholder or his agent or proxy may be proved by the
certificate of any notary public or other officer

                                       36
<PAGE>

authorized to take acknowledgment of deeds, that the Person executing such
instrument acknowledged to such notary public or other such officer the
execution thereof, or by an affidavit of a witness to such execution sworn to
before any such notary public or other officer. Where such execution is by an
officer of a corporation or association or a member of a partnership on behalf
of such corporation, association or partnership, as the case may be, or by any
other Person acting in a representative capacity, such certificate or affidavit
shall also constitute sufficient proof of such Person's authority. The holding
of Securities shall be proved by the Security register or by a certificate of
the registrar thereof. The Issuer may set a record date for purposes of
determining the identity of holders of Securities of any series entitled to vote
or consent to any action referred to in Section 6.01, which record date may be
set at any time or from time to time by notice to the Trustee, for any date or
dates (in the case of any adjournment or reconsideration) not more than 60 days
nor less than five days prior to the proposed date of such vote or consent, and
thereafter, notwithstanding any other provisions hereof, only holders of
Securities of such series of record on such record date shall be entitled to so
vote or give such consent or revoke such vote or consent.

     Section 6.03. Holders to be Treated as Owners. Prior to due presentment of
a Security for registration of transfer, the Issuer, the Trustee and any agent
of the Issuer or the Trustee may deem and treat the person in whose name any
Security shall be registered upon the Security register for such series as the
absolute owner of such Security (whether or not such Security shall be overdue
and notwithstanding any notation of ownership or other writing thereon) for the
purpose of receiving payment of or on account of the principal of and, subject
to the provisions of this Indenture, interest on such Security and for all other
purposes; and neither the Issuer nor the Trustee nor any agent of the Issuer or
the Trustee shall be affected by any notice to the contrary. All such payments
so made to any such person, or upon his order, shall be valid, and, to the
extent of the sum or sums so paid, effectual to satisfy and discharge the
liability for moneys payable upon any such Security.

     Section 6.04. Securities Owned by Issuer Deemed Not Outstanding. In
determining whether the Holders of the requisite aggregate principal amount of
Outstanding Securities of any or all series have concurred in any direction,
consent or waiver under this Indenture, Securities which are owned by the Issuer
or any other obligor on the Securities with respect to which such determination
is being made or by any person directly or indirectly controlling or controlled
by or under direct or indirect common control with the Issuer or any other
obligor on the Securities with respect to which such determination is being made
shall be disregarded and deemed not to be Outstanding for the purpose of any
such determination, except that for the purpose of determining whether the
Trustee shall be protected in relying on any such direction, consent or waiver
only Securities as to which the Trustee has received written notice are so owned
shall be so disregarded. Securities so owned which have been pledged in good
faith may be regarded as Outstanding if the pledgee establishes to the
satisfaction of the Trustee the pledgee's right so to act with respect to such
Securities and that the pledgee is not the Issuer or any other obligor upon the
Securities or any person directly or indirectly controlling or controlled by or
under direct or indirect common control with the Issuer or any other obligor on
the Securities. In case of a dispute as to such right, the advice of counsel
shall be full protection in respect of any decision made by the Trustee in
accordance with such advice. Upon request of the Trustee, the Issuer shall
furnish to the Trustee promptly an Officers' Certificate listing and identifying
all Securities, if any, known by the Issuer to be owned or held by or for the
account of any of the above-

                                       37
<PAGE>

described persons; and, subject to Sections 5.01 and 5.02, the Trustee shall be
entitled to accept such Officers' Certificate as conclusive evidence of the
facts therein set forth and of the fact that all Securities not listed therein
are Outstanding for the purpose of any such determination.

     Section 6.05. Right of Revocation of Action Taken. At any time prior to
(but not after) the evidencing to the Trustee, as provided in Section 6.01, of
the taking of any action by the Holders of the percentage in aggregate principal
amount of the Securities of any or all series, as the case may be, specified in
this Indenture in connection with such action, any Holder of a Security the
serial number of which is shown by the evidence to be included among the serial
numbers of the Securities the Holders of which have consented to such action
may, by filing written notice at the Corporate Trust Office and upon proof of
holding as provided in this Article, revoke such action so far as concerns such
Security. Except as aforesaid any such action taken by the Holder of any
Security shall be conclusive and binding upon such Holder and upon all future
Holders and owners of such Security and of any Securities issued in exchange or
substitution therefor, irrespective of whether or not any notation in regard
thereto is made upon any such Security. Any action taken by the Holders of the
percentage in aggregate principal amount of the Securities of any or all series,
as the case may be, specified in this Indenture in connection with such action
shall be conclusively binding upon the Issuer, the Trustee and the Holders of
all the Securities affected by such action.

                                   Article 7
                             SUPPLEMENTAL INDENTURES

     Section 7.01. Supplemental Indentures Without Consent of Securityholders.
The Issuer, when authorized by a resolution of its Board of Directors certified
to the Trustee, and the Trustee may from time to time and at any time enter into
an indenture or indentures supplemental hereto for one or more of the following
purposes:

     (a) to evidence the succession of another corporation to the Issuer, or
successive successions, and the assumption by the successor corporation of the
covenants, agreements and obligations of the Issuer pursuant to Article 8;

     (b) to cure any ambiguity or to correct or supplement any provision
contained herein or in any supplemental indenture which may be defective or
inconsistent with any other provision contained herein or in any supplemental
indenture; or to make such other provisions in regard to matters or questions
arising under this Indenture or under any supplemental indenture as the Board of
Directors may deem necessary or desirable and which shall not adversely affect
the interests of the Holders of the Securities in any material respect;

     (c) to establish the form or terms of Securities of any series as permitted
by Sections 2.01 and 2.03;

     (d) to evidence and provide for the acceptance of appointment hereunder by
a successor trustee with respect to the Securities of one or more series and to
add to or change any of the provisions of this Indenture as shall be necessary
to provide for or facilitate the administration of the trusts hereunder by more
than one trustee, pursuant to the requirements of Section 5.10;

                                       38
<PAGE>

     (e) to comply with any requirements of the Commission in connection with
the qualification of this Indenture under the Trust Indenture Act of 1939;

     (f) to provide for uncertificated or Unregistered Securities and to make
all appropriate changes for such purpose;

     (g) to make any change that does not adversely affect the rights of any
Holder;

     (h) as provided by or pursuant to a Board Resolution or indenture
supplemental hereto establishing the terms of one or more series of Securities;

     (i) to add to the covenants of the Issuer such new covenants, restrictions,
conditions or provisions as its Board of Directors shall consider to be for the
protection of the Holders of Securities, and with respect to which the Trustee
has received an Opinion of Counsel to a similar effect, and to make the
occurrence, or the occurrence and continuance, of a default in any such
additional covenants, restrictions, conditions or provisions an Event of
Default; provided, that in respect of any such additional covenant, restriction,
condition or provision such supplemental indenture may provide for a particular
period of grace after default (which period may be shorter or longer than that
allowed in the case of other defaults) or may provide for an immediate
enforcement upon such an Event of Default or may limit the remedies available to
the Trustee upon such an Event of Default or may limit the right of the Holders
of a majority in aggregate principal amount of the Securities of such series to
waive such an Event of Default; or

     (j) to make any change so long as no Securities are Outstanding.

     The Trustee is hereby authorized to join with the Issuer in the execution
of any such supplemental indenture, to make any further appropriate agreements
and stipulations which may be therein contained and to accept the conveyance,
transfer, assignment, mortgage or pledge of any property thereunder, but the
Trustee shall not be obligated to enter into any such supplemental indenture
which affects the Trustee's own rights, duties or immunities under this
Indenture or otherwise.

     Any supplemental indenture authorized by the provisions of this section may
be executed without the consent of the Holders of any of the Securities at the
time outstanding, notwithstanding any of the provisions of Section 7.02.

     Section 7.02. Supplemental Indentures With Consent of Securityholders. With
the consent (evidenced as provided in Article 6) of the Holders of not less than
a majority in aggregate principal amount of the Securities at the time
Outstanding of all series affected by such supplemental indenture (voting as one
class), the Issuer, when authorized by a resolution of its Board of Directors,
and the Trustee may, from time to time and at any time, enter into an indenture
or indentures supplemental hereto for the purpose of adding any provisions to or
changing in any manner or eliminating any of the provisions of this Indenture or
of any supplemental indenture or of modifying in any manner the rights of the
Holders of the Securities of each such series; provided, that no such
supplemental indenture shall without the consent of each Holder affected
thereby:

                                       39
<PAGE>

          (i) change the stated maturity of the Principal of, or any sinking
     fund obligation or any installment of interest on, such Holder's Security;

          (ii) reduce the Principal thereof or the rate of interest thereon, or
     any premium payable with respect thereto;

          (iii) change any place of payment where, or the currency in which, any
     Security or any premium or the interest thereon is payable;

          (iv) change the provisions for calculating the optional redemption
     price, including the definitions relating thereto;

          (v) make any change to Section 4.07 or 4.10 (except to include other
     provisions subject to Section 4.10);

          (vi) reduce the percentage in principal amount of outstanding
     Securities of the relevant series the consent of whose Holders is required
     for any such supplemental indenture, for any waiver of compliance with any
     provisions of this Indenture or any defaults and their consequences
     provided for in this Indenture;

          (vii) alter or impair the right to convert any Security at the rate
     and upon the terms provided in Article 12;

          (viii) waive a default in the payment of Principal of or interest on
     any Security of such Holder (except pursuant to a rescission of
     acceleration pursuant to Section 4.01);

          (ix) adversely affect the rights of such Holder under any mandatory
     redemption or repurchase provision or any right of redemption or repurchase
     at the option of such Holder;

          (x) modify any of the provisions of this Section 7.02, except to
     increase any such percentage or to provide that certain other provisions of
     this Indenture cannot be modified or waived without the consent of the
     Holder of each outstanding Security affected thereby; or

          (xi) change or waive any provision that, pursuant to a board
     resolution or indenture supplemental hereto establishing the terms of one
     or more series of Securities, is prohibited to be so changed or waived.

     Upon the written request of the Issuer, accompanied by a copy of a
resolution of the Board of Directors certified by the secretary or an assistant
secretary of the Issuer authorizing the execution of any such supplemental
indenture, and upon the filing with the Trustee of evidence of the consent of
Securityholders as aforesaid and other documents, if any, required by Section
6.01, the Trustee shall join with the Issuer in the execution of such
supplemental indenture unless such 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 supplemental indenture.

                                       40
<PAGE>

     It shall not be necessary for the consent of the Securityholders under this
section to approve the particular form of any proposed supplemental indenture,
but it shall be sufficient if such consent shall approve the substance thereof.

     Promptly after the execution by the Issuer and the Trustee of any
supplemental indenture pursuant to the provisions of this Section, the Issuer
shall mail a notice thereof by first class mail to the Holders of Securities of
each series affected thereby at their addresses as they shall appear on the
registry books of the Issuer, setting forth in general terms the substance of
such supplemental indenture. Any failure of the Issuer to mail such notice, or
any defect therein, shall not, however, in any way impair or affect the validity
of any such supplemental indenture.

     Section 7.03. Effect of Supplemental Indenture. Upon the execution of any
supplemental indenture pursuant to the provisions hereof, this Indenture shall
be and be deemed to be modified and amended in accordance therewith and the
respective rights, limitations of rights, obligations, duties and immunities
under this Indenture of the Trustee, the Issuer and the Holders of Securities of
each series affected thereby shall thereafter be determined, exercised and
enforced hereunder subject in all respects to such modifications and amendments,
and all the terms and conditions of any such supplemental indenture shall be and
be deemed to be part of the terms and conditions of this Indenture for any and
all purposes.

     Section 7.04. Documents to Be Given to Trustee. The Trustee, subject to the
provisions of Sections 5.01 and 5.02, may receive an Officers' Certificate and
an Opinion of Counsel as conclusive evidence that any supplemental indenture
executed pursuant to this Article 7 complies with the applicable provisions of
this Indenture.

     Section 7.05. Notation on Securities in Respect of Supplemental Indentures.
Securities of any series authenticated and delivered after the execution of any
supplemental indenture pursuant to the provisions of this Article may bear a
notation in form approved by the Trustee for such series as to any matter
provided for by such supplemental indenture or as to any action taken at any
such meeting. If the Issuer or the Trustee shall so determine, new Securities of
any series so modified as to conform, in the opinion of the Trustee and the
Board of Directors, to any modification of this Indenture contained in any such
supplemental indenture may be prepared by the Issuer, authenticated by the
Trustee and delivered in exchange for the Securities of such series then
outstanding.

                                   Article 8
                    CONSOLIDATION, MERGER, SALE OR CONVEYANCE

     Section 8.01. Issuer May Consolidate, etc., on Certain Terms. The Issuer
covenants that it will not merge or consolidate with any other Person or sell,
convey, transfer, lease or otherwise dispose of all or substantially all of its
property and assets to any Person (other than a consolidation with or merger
with or into or a sale, conveyance, transfer, lease or other disposition to a
Wholly-Owned Subsidiary with a positive net worth; provided that, in connection
with any such merger of the Issuer with a Wholly-Owned Subsidiary, no
consideration (other than common stock) in the surviving person or the Issuer
shall be issued or distributed to the stockholders of the Issuer), unless (i)
either (x) the Issuer shall be the

                                       41
<PAGE>

continuing corporation, or the successor corporation or (y) the Person formed by
such consolidation or into which the Issuer is merged or that acquires by sale
or conveyance substantially all the assets of the Issuer (if other than the
Issuer) shall be a corporation or limited liability company organized and
validly existing under the laws of the United States of America or any
jurisdiction thereof and shall expressly assume the due and punctual payment of
the principal of and interest on all the Securities, according to their tenor,
and the due and punctual performance and observance of all of the covenants and
conditions of this Indenture to be performed or observed by the Issuer, by
supplemental indenture satisfactory to the Trustee, executed and delivered to
the Trustee by such Person, (ii) immediately after giving effect to such
transaction, no default or Event of Default shall have occurred and be
continuing and (iii) the Issuer delivers to the Trustee an Officers' Certificate
and Opinion of Counsel, in each case stating that such consolidation, merger or
transfer and such supplemental indenture complies with this Section 8.01 and
that all conditions precedent provided for herein relating to such transaction
have been complied with; provided, however, that the foregoing limitations shall
not apply if, in the good faith determination of the Board of Directors, whose
determination shall be evidenced by a board resolution certified to the Trustee,
the principal purpose of such transaction is to change the state of
incorporation of the Issuer; and provided further that any such transaction
shall not have as one of its purposes the evasion of the foregoing limitations.

     Section 8.02. Successor Corporation Substituted. In case of any such
consolidation, merger, sale, conveyance, transfer, lease or other disposition,
and following such an assumption by the successor Person, such successor Person
shall succeed to and be substituted for the Issuer, with the same effect as if
it had been named herein. Such successor Person may cause to be signed, and may
issue either in its own name or in the name of the Issuer prior to such
succession any or all of the Securities issuable hereunder which theretofore
shall not have been signed by the Issuer and delivered to the Trustee; and, upon
the order of such successor Person instead of the Issuer and subject to all the
terms, conditions and limitations in this Indenture prescribed, the Trustee,
pursuant to the terms hereof, shall authenticate and shall deliver any
Securities which previously shall have been signed and delivered by the officers
of the Issuer to the Trustee for authentication, and any Securities which such
successor Person thereafter shall cause to be signed and delivered to the
Trustee for that purpose. All of the Securities so issued shall in all respects
have the same legal rank and benefit under this Indenture as the Securities
theretofore or thereafter issued in accordance with the terms of this Indenture
as though all of such Securities had been issued at the date of the execution
hereof.

     In case of any such consolidation, merger, sale, conveyance, transfer,
lease or other disposition, such changes in phraseology and form (but not in
substance) may be made in the Securities thereafter to be issued as may be

<PAGE>

hereunder under this Indenture that remains unclaimed for two years; provided

shall cause to be published at the expense of the Issuer once in an Authorized
Newspaper or mail to each Holder entitled to such money at such Holder's address
(as set forth in the register) notice that such money remains unclaimed and that
after a date specified therein (which shall be at least 30 days from the date of
such publication or mailing) any unclaimed balance of such money then remaining

such money must look to the Issuer for payment as unsecured general creditors
unless an abandoned property law designates another Person, and all liability of
the Trustee and such Paying Agent with respect to such money shall cease.

                                   Article 10
                            MISCELLANEOUS PROVISIONS

     Section 10.01. Incorporators, Stockholders, Officers and Directors Exempt
from Individual Liability. No recourse under or upon any obligation, covenant or
agreement contained in this Indenture, the Cable Guarantees or in any Security,
or because of any indebtedness evidenced thereby, shall be had against any
incorporator, as such, or against any past, present or future stockholder,
officer, director or employee, as such, of the Issuer, any Cable Guarantor or of
any successor Person thereof, either directly or through the Issuer or any Cable
Guarantor or any successor Person thereof, under any rule of law, statute or
constitutional provision or by the enforcement of any assessment or by any legal
or equitable proceeding or otherwise, all such liability being expressly waived
and released by the acceptance of the Securities by the holders thereof and as
part of the consideration for the issue of the Securities.

     Section 10.02. Provisions of Indenture for the Sole Benefit of Parties and
Securityholders. Nothing in this Indenture or in the Securities, expressed or
implied, shall give or be construed to give to any person, firm or corporation,
other than the parties hereto and their successors and the Holders of the
Securities, any legal or equitable right, remedy or claim under this Indenture
or under any covenant or provision herein contained, all such covenants and
provisions being for the sole benefit of the parties hereto and their successors
and of the Holders of the Securities.

     Section 10.03. Successors and Assigns of Issuer Bound by Indenture. All the
covenants, stipulations, promises and agreements in this Indenture contained by
or in behalf of the Issuer shall bind its successors and assigns, whether so
expressed or not.

     Section 10.04. Notices and Demands on Issuer, Trustee and Securityholders.
Any notice or demand which by any provision of this Indenture is required or
permitted to be given or served by the Trustee or by the Holders of Securities
to or on the Issuer may be given or served by being deposited postage prepaid,
first-class mail (except as otherwise specifically provided herein) addressed
(until another address of the Issuer is filed by the Issuer with the Trustee) to
Comcast Corporation at 1500 Market Street, Philadelphia, Pennsylvania
19102-2148, Attention: Treasurer. Any notice, direction, request or demand by

<PAGE>

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

     In case, by reason of the suspension of or irregularities in regular mail
service, it shall be impracticable to mail notice to the Issuer and
Securityholders when such notice is required to be given pursuant to any
provision of this Indenture, then any manner of giving such notice as shall be
satisfactory to the Trustee shall be deemed to be a sufficient giving of such
notice.

     Section 10.05. Officers' Certificates and Opinions of Counsel; Statements
to be Contained Therein. Upon any application or demand by the Issuer to the
Trustee to take any action under any of the provisions of this Indenture, the
Issuer shall furnish to the Trustee an Officers' Certificate stating that all
conditions precedent provided for in this Indenture relating to the proposed
action have been complied with and an Opinion of Counsel stating that in the
opinion of such counsel all such conditions precedent have been complied with,
except that in the case of any such application or demand as to which the
furnishing of such documents is specifically required by any provision of this
Indenture relating to such particular application or demand, no additional
certificate or opinion need be furnished.

     Each certificate or opinion provided for in this Indenture and delivered to
the Trustee with respect to compliance with a condition or covenant provided for
in this Indenture shall include (a) a statement that the person making such
certificate or opinion has read such covenant or condition, (b) a brief
statement as to the nature and scope of the examination or investigation upon
which the statements or opinions contained in such certificate or opinion are
based, (c) a statement that, in the opinion of such person, he has made such
examination or investigation as is necessary to enable him to express an
informed opinion as to whether or not such covenant or condition has been
complied with and (d) a statement as to whether or not, in the opinion of such
person, such condition or covenant has been complied with.

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

                                       47
<PAGE>

     Any certificate, statement or opinion of an officer of the Issuer or of
counsel may be based, insofar as it relates to accounting matters, upon a
certificate or opinion of or representations by an accountant or firm of
accountants in the employ of the Issuer, unless such officer or counsel, as the
case may be, knows that the certificate or opinion or representations with
respect to the accounting matters upon which his certificate, statement or
opinion may be based as aforesaid are erroneous, or in the exercise of
reasonable care should know that the same are erroneous.

     Any certificate or opinion of any independent firm of public accountants
filed with the Trustee shall contain a statement that such firm is independent.

     Section 10.06. Payments Due on Saturdays, Sundays and Holidays. If the date
of maturity of interest on or principal of the Securities of any series or the
date fixed for redemption or repayment of any such Security shall not be a
Business Day, then payment of interest or principal need not be made on such
date, but may be made on the next succeeding Business Day with the same force
and effect as if made on the date of maturity or the date fixed for redemption,
and no interest shall accrue for the period after such date.

     Section 10.07. Conflict of Any Provision of Indenture with Trust Indenture
Act of 1939. If and to the extent that any provision of this Indenture limits,
qualifies or conflicts with another provision included in this Indenture by
operation of Sections 310 to 317, inclusive, of the Trust Indenture Act of 1939
(an "incorporated provision"), such incorporated provision shall control.

     Section 10.08. New York Law to Govern. This Indenture, including any Cable
Guarantee, and each Security shall be deemed to be a contract under the laws of
the State of New York, and for all purposes shall be construed in accordance
with the laws of such State.

     Section 10.09. Counterparts. This Indenture may be executed in any number
of counterparts, each of which shall be an original; but such counterparts shall
together constitute but one and the same instrument.

     Section 10.10. Effect of Headings. The Article and Section headings herein
and the Table of Contents are for convenience only and shall not affect the
construction hereof.

                                   Article 11
                   REDEMPTION OF SECURITIES AND SINKING FUNDS

     Section 11.01. Applicability of Article. The provisions of this Article
shall be applicable to the Securities of any series which are redeemable before
their maturity or to any sinking fund for the retirement of Securities of a
series except as otherwise specified as contemplated by Section 2.03 for
Securities of such series.

     Section 11.02. Notice of Redemption; Partial Redemptions. Notice of
redemption to the Holders of Securities of any series to be redeemed as a whole
or in part at the option of the Issuer shall be given by mailing notice of such
redemption by first class mail, postage prepaid, at least 30 days and not more
than 60 days prior to the date fixed for redemption to such Holders of
Securities of such series at their last addresses as they shall appear upon the
registry books. Any

                                       48
<PAGE>

notice which is mailed in the manner herein provided shall be conclusively
presumed to have been duly given, whether or not the Holder receives the notice.
Failure to give notice by mail, or any defect in the notice to the Holder of any
Security of a series designated for redemption as a whole or in part shall not
affect the validity of the proceedings for the redemption of any other Security
of such series.

     The notice of redemption to each such Holder shall specify the CUSIP
numbers of such Securities to be redeemed, the principal amount of each Security
of such series held by such Holder to be redeemed, the date fixed for
redemption, the redemption price, the place or places of payment, that payment
will be made upon presentation and surrender of such Securities, that such
redemption is pursuant to the mandatory or optional sinking fund, or both, if
such be the case, that interest accrued to the date fixed for redemption will be
paid as specified in such notice and that on and after said date interest
thereon or on the portions thereof to be redeemed will cease to accrue. In case
any Security of a series is to be redeemed in part only the notice of redemption
shall state the portion of the principal amount thereof to be redeemed, the
method the Trustee shall use to determine such Securities to be redeemed as
specified in the last paragraph of this Section 11.02, if applicable, and shall
state that on and after the date fixed for redemption, upon surrender of such
Security, a new Security or Securities of such series in principal amount equal
to the unredeemed portion thereof will be issued.

     The notice of redemption of Securities of any series to be redeemed at the
option of the Issuer shall be given by the Issuer or, at the Issuer's written
request, by the Trustee in the name and at the expense of the Issuer.

     By 10:00 a.m. (New York City time) on the redemption date specified in the
notice of redemption given as provided in this Section, the Issuer will deposit
with the Trustee or with one or more paying agents (or, if the Issuer is acting
as its own paying agent, set aside, segregate and hold in trust as provided in
Section 3.03) an amount of money sufficient to redeem on the redemption date all
the Securities of such series so called for redemption at the appropriate
redemption price, together with accrued interest to the date fixed for
redemption. If less than all the outstanding Securities of a series are to be
redeemed, the Issuer will deliver to the Trustee at least 70 days (unless a
shorter period shall be satisfactory to the Trustee) prior to the date fixed for
redemption an Officers' Certificate stating the aggregate principal amount of
Securities to be redeemed.

     In the case of the redemption of all of the Securities of a series
outstanding, the Issuer shall notify the Trustee in writing of the redemption
date 45 days (unless a shorter period shall be satisfactory to the Trustee)
prior to the redemption date.

     If less than all the Securities of a series are to be redeemed, the Trustee
shall select, pro rata or by lot or in such manner as it shall deem appropriate
and fair, Securities of such series to be redeemed in whole or in part.
Securities of a series may be redeemed in part in multiples equal to the minimum
authorized denomination for Securities of such series or any multiple thereof.
The Trustee shall promptly notify the Issuer in writing of the Securities of
such series selected for redemption and, in the case of any Securities of such
series selected for partial redemption, the principal amount thereof to be
redeemed. For all purposes of this Indenture, unless the context otherwise
requires, all provisions relating to the redemption of Securities of

                                       49
<PAGE>

any series shall relate, in the case of any Security redeemed or to be redeemed
only in part, to the portion of the principal amount of such Security which has
been or is to be redeemed.

     Section 11.03. Payment of Securities Called for Redemption. If notice of
redemption has been given as above provided, the Securities or portions of
Securities specified in such notice shall become due and payable on the date and
at the place stated in such notice at the applicable redemption price, together
with interest accrued to the date fixed for redemption, and on and after said
date (unless the Issuer shall default in the payment of such Securities at the
redemption price, together with interest accrued to said date) interest on the
Securities or portions of Securities so called for redemption shall cease to
accrue and, except as provided in Sections 5.05 and 9.04, such Securities shall
cease from and after the date fixed for redemption to be entitled to any benefit
or security under this Indenture, and the Holders thereof shall have no right in
respect of such Securities except the right to receive the redemption price
thereof and unpaid interest to the date fixed for redemption. On presentation
and surrender of such Securities at a place of payment specified in said notice,
said Securities or the specified portions thereof shall be paid and redeemed by
the Issuer at the applicable redemption price, together with interest accrued
thereon to the date fixed for redemption; provided that any semiannual payment
of interest becoming due on the date fixed for redemption shall be payable to
the Holders of such Securities registered as such on the relevant record date
subject to the terms and provisions of Section 2.07 hereof.

     If any Security called for redemption shall not be so paid upon surrender
thereof for redemption, the principal shall, until paid or duly provided for,
bear interest from the date fixed for redemption at the rate of interest or
Yield to Maturity (in the case of an Original Issue Discount Security) borne by
the Security.

     Upon presentation of any Security redeemed in part only, the Issuer shall
execute and the Trustee shall authenticate and deliver to or on the order of the
Holder thereof, at the expense of the Issuer, a new Security or Securities of
such series, of authorized denominations, in principal amount equal to the
unredeemed portion of the Security so presented pursuant to Sections 2.04, 2.05
and 2.06.

     Section 11.04. Exclusion of Certain Securities from Eligibility for
Selection for Redemption. Securities shall be excluded from eligibility for
selection for redemption if they are identified by registration and certificate
number in a written statement signed by an authorized officer of the Issuer and
delivered to the Trustee at least 40 days prior to the last date on which notice
of redemption may be given as being owned of record and beneficially by, and not
pledged or hypothecated by either (a) the Issuer or (b) an entity specifically
identified in such written statement directly or indirectly controlling or
controlled by or under direct or indirect common control with the Issuer.

     Section 11.05. Mandatory and Optional Sinking Funds. The minimum amount of
any sinking fund payment provided for by the terms of Securities of any series
is herein referred to as a "mandatory sinking fund payment", and any payment in
excess of such minimum amount provided for by the terms of Securities of any
series is herein referred to as an "optional sinking fund payment". The date on
which a sinking fund payment is to be made is herein referred to as the "sinking
fund payment date".

                                       50
<PAGE>

     In lieu of making all or any part of any mandatory sinking fund payment
with respect to any series of Securities in cash, the Issuer may at its option
(a) deliver to the Trustee Securities of such series theretofore purchased or
otherwise acquired (except upon redemption pursuant to the mandatory sinking
fund) by the Issuer or receive credit for Securities of such series (not
previously so credited) theretofore purchased or otherwise acquired (except as
aforesaid) by the Issuer and delivered to the Trustee for cancellation pursuant
to Section 2.10, (b) receive credit for optional sinking fund payments (not
previously so credited) made pursuant to this Section, or (c) receive credit for
Securities of such series (not previously so credited) redeemed by the Issuer
through any optional redemption provision contained in the terms of such series.
Securities so delivered or credited shall be received or credited by the Trustee
at the sinking fund redemption price specified in such Securities.

     On or before the sixtieth day next preceding each sinking fund payment date
for any series, the Issuer will deliver to the Trustee an Officers' Certificate
(a) specifying the portion of the mandatory sinking fund payment to be satisfied
by payment of cash and the portion to be satisfied by credit of Securities of
such series, (b) stating that none of the Securities of such series has
theretofore been so credited, (c) stating that no defaults in the payment of
interest or Events of Default with respect to such series have occurred (which
have not been waived or cured) and are continuing and (d) stating whether or not
the Issuer intends to exercise its right to make an optional sinking fund
payment with respect to such series and, if so, specifying the amount of such
optional sinking fund payment which the Issuer intends to pay on or before the
next succeeding sinking fund payment date. Any Securities of such series to be
credited and required to be delivered to the Trustee in order for the Issuer to
be entitled to credit therefor as aforesaid which have not theretofore been
delivered to the Trustee shall be delivered for cancellation pursuant to Section
2.10 to the Trustee with such written statement (or reasonably promptly
thereafter if acceptable to the Trustee). Such Officers' Certificate shall be
irrevocable and upon its receipt by the Trustee the Issuer shall become
unconditionally obligated to make all the cash payments or payments therein
referred to, if any, on or before the next succeeding sinking fund payment date.
Failure of the Issuer, on or before any such sixtieth day, to deliver such
written statement and Securities specified in this paragraph, if any, shall not
constitute a default but shall constitute, on and as of such date, the
irrevocable election of the Issuer (i) that the mandatory sinking fund payment
for such series due on the next succeeding sinking fund payment date shall be
paid entirely in cash without the option to deliver or credit Securities of such
series in respect thereof and (ii) that the Issuer will make no optional sinking
fund payment with respect to such series as provided in this Section.

     If any sinking fund payment or payments (mandatory or optional or both) to
be made in cash on the next succeeding sinking fund payment date plus any unused
balance of any preceding sinking fund payments made in cash shall exceed $50,000
(or a lesser sum if the Issuer shall so request in writing) with respect to the
Securities of any particular series, such cash shall be applied on the next
succeeding sinking fund payment date to the redemption of Securities of such
series at the sinking fund redemption price together with accrued interest to
the date fixed for redemption. If such amount shall be $50,000 or less and the
Issuer makes no such request then it shall be carried over until a sum in excess
of $50,000 is available together with accrued interest to the date fixed for
redemption. The Trustee shall select, in the manner provided in Section 11.02,
for redemption on such sinking fund payment date a sufficient principal amount
of Securities of such series to absorb said cash, as nearly as may be, and shall
(if requested in

                                       51
<PAGE>

writing by the Issuer) inform the Issuer of the serial numbers of the Securities
of such series (or portions thereof) so selected. Securities of any series which
are identified in an Officers' Certificate at least 60 days prior to the sinking
fund payment date as being beneficially owned by, and not pledged or
hypothecated by, the Issuer or an entity directly or indirectly controlling or
controlled by or under direct or indirect common control with the Issuer shall
be excluded from Securities of such series eligible for selection for
redemption. The Issuer or the Trustee, in the name and at the expense of the
Issuer (if the Issuer shall so request the Trustee in writing) shall cause
notice of redemption of the Securities of such series to be given in the manner
provided in Section 11.02 (and with the effect provided in Section 11.03) for
the redemption of Securities of such series in part at the option of the Issuer.
The amount of any sinking fund payments not so applied or allocated to the
redemption of Securities of such series shall be added to the next cash sinking
fund payment for such series and, together with such payment, shall be applied
in accordance with the provisions of this Section. Any and all sinking fund
moneys held on the stated maturity date of the Securities of any particular
series (or earlier, if such maturity is accelerated), which are not held for the
payment or redemption of particular Securities of such series shall be applied,
together with other moneys, if necessary, sufficient for the purpose, to the
payment of the principal of, and interest on, the Securities of such series at
maturity.

     At least one Business Day before each sinking fund payment date, the Issuer
shall pay to the Trustee in cash or shall otherwise provide for the payment of
all interest accrued to the date fixed for redemption on Securities to be
redeemed on the next following sinking fund payment date.

     The Trustee shall not redeem or cause to be redeemed any Securities of a
series with sinking fund moneys or mail any notice of redemption of Securities
for such series by operation of the sinking fund during the continuance of a
default in payment of interest on such Securities or of any Event of Default if
the Trustee has received written notice thereof at least three Business Days
prior to any payment hereunder except that, where the mailing of notice of
redemption of any Securities shall theretofore have been made, the Trustee shall
redeem or cause to be redeemed such Securities, provided that it shall have
received from the Issuer a sum sufficient for such redemption. Except as
aforesaid, if the Trustee has received written notice of such default or Event
of Default at least three Business Days prior to any payment hereunder, any
moneys in the sinking fund for such series at the time when any such default or
Event of Default shall occur, and any moneys thereafter paid into the sinking
fund, shall, during the continuance of such default or Event of Default, be
deemed to have been collected under Article 4 and held for the payment of all
such Securities. In case such Event of Default shall have been waived as
provided in Section 4.10 or the default cured on or before the sixtieth day
preceding the sinking fund payment date in any year, such moneys shall
thereafter be applied on the next succeeding sinking fund payment date in
accordance with this section to the redemption of such Securities.

     Section 11.06. Conversion Arrangement On Call For Redemption. In connection
with any redemption of Securities, the Issuer shall deposit the amount due in
connection with such redemption as required by Section 11.02 or it may arrange
for the purchase and conversion of any Securities called for redemption by an
agreement with one or more investment bankers or other purchasers to purchase
such Securities and to make the deposit required of it by Section 11.02 on its
behalf by paying to the Trustee or the Paying Agent in trust for the
Securityholders,

                                       52
<PAGE>

on or before 10:00 a.m. New York time on the redemption date, an amount no less
than the redemption price, together with interest, if any, accrued to the
redemption date of such Securities, in immediately available funds.
Notwithstanding anytime to the contrary contained in this Article 11, the
obligation of the Issuer to pay the redemption price of such Securities,
including all accrued interest, if any, shall be deemed to be satisfied and
discharged to the extent such amount is so paid by such purchasers. If such an
agreement is entered into, any Securities not duly surrendered for conversion by
the holders thereof may, at the option of the Issuer, be deemed, to the fullest
extent permitted by law, acquired by such purchasers from such holders and
(notwithstanding anything to the contrary contained in Article 12) surrendered
by such purchasers for conversion, all as of immediately prior to the close of
business on the last day on which Securities of such series called for
redemption may be converted in accordance with this Indenture and the terms of
such Securities, subject to payment of the above amount aforesaid. The Trustee
or the Paying Agent shall hold and pay to the Securityholders whose Securities
are selected for redemption any such amount paid to it in the same manner as it
would moneys deposited with it by the Issuer for the redemption of Securities.
Without the Trustee's and the Paying Agent's prior written consent, no
arrangement between the Issuer and such purchasers for the purchase and
conversion of any Securities shall increase or otherwise affect any of the
powers, duties, responsibilities or obligations of the Trustee as set forth in
this Indenture, and the Issuer agrees to indemnify the Trustee from, and hold it
harmless against, any loss, liability or expense arising out of or in connection
with any such arrangement for the purchase and conversion of any Securities
between the Issuer and such purchasers, including the costs and expenses
incurred by the Trustee and the Paying Agent in the defense of any claim or
liability arising out of or in connection with the exercise or performance of
any of its powers, duties, responsibilities or obligations under this Indenture.

                                   Article 12
                            CONVERSION OF SECURITIES

     Section 12.01. Applicability of Article. Securities of any series which are
convertible into Capital Stock at the option of the Securityholder shall be
convertible in accordance with their terms and (unless otherwise specified as
contemplated by Section 2.03 for Securities of any series) in accordance with
this Article. Each reference in this Article 12 to "a Security" or "the
Securities" refers to the Securities of the particular series that is
convertible into Capital Stock. Each reference in this Article to "Capital
Stock" into which Securities of any series are convertible refers to the class
of Capital Stock into which the Securities of such series are convertible in
accordance with their terms (as specified as contemplated by Section 2.03). If
more than one series of Securities with conversion privileges are outstanding at
any time, the provisions of this Article 12 shall be applied separately to each
such series.

     Section 12.02. Right of Securityholders to Convert Securities. Subject to
and upon compliance with the terms of the Securities and the provisions of
Section 11.06 and this Article 12, at the option of the holder thereof, any
Security of any series of any authorized denomination, or any portion of the
principal amount thereof which is $1,000 or any integral multiple of $1,000,
may, at any time during the period specified in the Securities of such series,
or in case such Security or portion thereof shall have been called for
redemption, then in respect of such Security or portion thereof until and
including, but not after (unless the Issuer shall

                                       53
<PAGE>

default in payment due upon the redemption thereof) the close of business on the
Business Day prior to the date fixed for redemption except that in the case of
redemption at the option of the Securityholder, if specified in the terms of
such Securities, such right shall terminate upon receipt of written notice of
the exercise of such option, be converted into duly authorized, validly issued,
fully paid and nonassessable shares of the class of Class A Common Stock and
Class A Special Common Stock, or combination thereof, as specified in such
Security, at the conversion rate for each $1,000 principal amount of Securities
(such initial conversion rate reflecting an initial conversion price specified
in such Security) in effect on the conversion date, or, in case an adjustment in
the conversion rate has taken place pursuant to the provisions of Section 12.05,
then at the applicable conversion rate as so adjusted, upon surrender of the
Security or Securities, the principal amount of which is so to be converted, to
the Issuer at any time during usual business hours at the office or agency to be
maintained by it in accordance with the provisions of Section 3.02, accompanied
by a written notice of election to convert as provided in Section 12.03 and, if
so required by the Issuer and the Trustee, by a written instrument or
instruments of transfer in form satisfactory to the Issuer and the Trustee duly
executed by the registered holder or his attorney duly authorized in writing.
All Securities surrendered for conversion shall, if surrendered to the Issuer or
any conversion agent, be delivered to the Trustee for cancellation and cancelled
by it, or shall, if surrendered to the Trustee, be cancelled by it, as provided
in Section 2.10.

     The initial conversion price or conversion rate in respect of a series of
Securities shall be as specified in the Securities of such series. The
conversion price or conversion rate will be subject to adjustment on the terms
set forth in Section 12.05 or such other or different terms, if any, as may be
specified by Section 2.03 for Securities of such series. Provisions of this
Indenture that apply to conversion of all of a Security also apply to conversion
of a portion of it.

     Section 12.03. Issuance of Shares of Capital Stock on Conversion. As
promptly as practicable after the surrender, as herein provided, of any Security
or Securities for conversion, the Issuer shall deliver or cause to be delivered
at its said office or agency to or upon the written order of the holder of the
Security or Securities so surrendered a certificate or certificates representing
the number of duly authorized, validly issued, fully paid and nonassessable
shares of Capital Stock into which such Security or Securities may be converted
in accordance with the terms thereof and the provisions of this Article 12.
Prior to delivery of such certificate or certificates, the Issuer shall require
a written notice at its said office or agency from the holder of the Security or
Securities so surrendered stating that the holder irrevocably elects to convert
such Security or Securities, or, if less than the entire principal amount
thereof is to be converted, stating the portion thereof to be converted. Such
notice shall also state the name or names (with address and social security or
other taxpayer identification number) in which said certificate or certificates
are to be issued. Such conversion shall be deemed to have been made at the time
that such Security or Securities shall have been surrendered for conversion and
such notice shall have been received by the Issuer or the Trustee, the rights of
the holder of such Security or Securities as a Securityholder shall cease at
such time, the person or persons entitled to receive the shares of Capital Stock
upon conversion of such Security or Securities shall be treated for all purposes
as having become the record holder or holders of such shares of Capital Stock at
such time and such conversion shall be at the conversion rate in effect at such
time. In the case of any Security of any series which is converted in part only,
upon such conversion, the Issuer shall execute and the Trustee shall
authenticate and deliver to the holder thereof, as requested by such holder, a

                                       54
<PAGE>

new Security or Securities of such series of authorized denominations in
aggregate principal amount equal to the unconverted portion of such Security.

     If the last day on which a Security may be converted is not a Business Day
in a place where a conversion agent is located, the Security may be surrendered
to that conversion agent on the next succeeding day that is a Business Day.

     The Issuer will not be required to deliver certificates for shares of
Capital Stock upon conversion while its stock transfer books are closed for a
meeting of shareholders or for the payment of dividends or for any other
purpose, but certificates for shares of Capital Stock shall be delivered as soon
as the stock transfer books shall again be opened.

     Section 12.04. No Payment or Adjustment for Interest or Dividends. Unless
otherwise specified as contemplated by Section 2.03 for Securities of such
series, Securities surrendered for conversion during the period from the close
of business on any regular record date (or special record date for payment of
defaulted interest) next preceding any interest payment date to the opening of
business on such interest payment date (except Securities called for redemption
on a redemption date within such period) when surrendered for conversion must be
accompanied by payment of an amount equal to the interest thereon which the
registered holder is to receive on such interest payment date. Payment of
interest shall be made, as of such interest payment date or such date, as the
case may be, to the holder of record of the Securities as of such regular, or
special record date, as applicable. Except where Securities surrendered for
conversion must be accompanied by payment as described above, no interest on
converted Securities will be payable by the Issuer on any interest payment date
subsequent to the date of conversion. No other payment or adjustment for
interest or dividends is to be made upon conversion. Notwithstanding the
foregoing, upon conversion of any Security with original issue discount, the
fixed number of shares of Capital Stock into which such Security is convertible
delivered by the Issuer to the holder thereof shall be applied, first, to pay
the accrued original issue discount attributable to the period from the date of
issuance to the date of conversion of such Security, and, second, to pay the
balance of the principal amount of such Security.

     Section 12.05. Adjustment of Conversion Rate. Unless otherwise specified as
contemplated by Section 2.03 for Securities of such series, the conversion rate
for Securities in effect at any time shall be subject to adjustment as follows:

     (a) In case the Issuer shall Error! Bookmark not defined. declare a
dividend or make a distribution on the class of Capital Stock into which
Securities of such series are convertible in shares of its Capital Stock, Error!
Bookmark not defined. subdivide the outstanding shares of the class of Capital
Stock into which Securities of such series are convertible into a greater number
of shares, Error! Bookmark not defined. combine the outstanding shares of the
class of Capital Stock into which Securities of such series are convertible into
a smaller number of shares, or Error! Bookmark not defined. issue by
reclassification of the shares, of the class of Capital Stock into which
Securities of such series are convertible (including any such reclassification
in connection with a consolidation or merger in which the Issuer is the
continuing corporation) any shares, the conversion rate for the Securities of
such series in effect at the time of the record date for such dividend or
distribution, or the effective date of such subdivision, combination or
reclassification, shall be proportionately adjusted so that the holder of any
Security of such series surrendered for conversion after such time shall be
entitled to receive the number and kind of shares which he would have owned or
have been entitled to receive had such Security been

                                       55
<PAGE>

converted immediately prior to such time. Similar adjustments shall be made
whenever any event listed above shall occur.

     (b) In case the Issuer shall fix a record date for the issuance of rights
or warrants to all holders of the class of Capital Stock into which Securities
of such series are convertible entitling them (for a period expiring within 45
days after such record date) to subscribe for or purchase shares of such class
of Capital Stock (or securities convertible into shares of such class of Capital
Stock) at a price per share (or, in the case of a right or warrant to purchase
securities convertible into such class of Capital Stock, having a conversion
price per share, after adding thereto the exercise price, computed on the basis
of the maximum number of shares of such class of Capital Stock issuable upon
conversion of such convertible securities, per share of such class of Capital
Stock, so issuable) less than the current market price per share of such class
of Capital Stock (as defined in subsection (e) below) on the date on which such
issuance was declared or otherwise announced by the Issuer (the "Determination
Date"), the number of shares of such class of Capital Stock into which each
$1,000 principal amount of Securities shall be convertible after such record
date shall be determined by multiplying the number of shares of such class of
Capital Stock into which such principal amount of Securities was convertible
immediately prior to such record date by a fraction, of which the numerator
shall be the number of shares of such class of Capital Stock outstanding on the
Determination Date plus the number of additional shares of such class of Capital
Stock offered for subscription or purchase (or in the case of a right or warrant
to purchase securities convertible into such class of Capital Stock, the
aggregate number of additional shares of such class of Capital Stock into which
the convertible securities so offered are initially convertible), and of which
the denominator shall be the number of shares of such class of Capital Stock
outstanding on the Determination Date plus the number of shares of such class of
Capital Stock obtained by dividing the aggregate offering price of the total
number of shares so offered (or, in the case of a right or warrant to purchase
securities convertible into such class of Capital Stock, the aggregate initial
conversion price of the convertible securities so offered, after adding thereto
the aggregate exercise price of such rights or warrants computed on the basis of
the maximum number of shares of such class of Capital Stock issuable upon
conversion of such convertible securities) by such current market price. Shares
of such class of Capital Stock of the Issuer owned by or held for the account of
the Issuer shall not be deemed outstanding for the purpose of any such
computation. Such adjustment shall be made successively whenever such a record
date is fixed; and to the extent that shares of such class of Capital Stock are
not delivered (or securities convertible into shares of such class of Capital
Stock are not delivered) after the expiration of such rights or warrants (or, in
the case of rights or warrants to purchase securities convertible into such
class of Capital Stock once exercised, the expiration of the conversion right of
such securities) the conversion rate shall be readjusted to the conversion rate
which would then be in effect had the adjustments made upon the issuance of such
rights or warrants (or securities convertible into shares) been made upon the
basis of delivery of only the number of shares actually delivered. In the event
that such rights or warrants are not so issued, the conversion rate shall again
be adjusted to be the conversion rate which would then be in effect if such
record date had not been fixed.

     (c) In case the Issuer shall fix a record date for the making of a
distribution to all holders of the class of Capital Stock into which Securities
of such series are convertible (including any such distribution made in
connection with a consolidation or merger in which the Issuer is the continuing
corporation) of evidences of its indebtedness or assets (excluding any

                                       56
<PAGE>

cash dividends paid from retained earnings and dividends payable in Capital
Stock for which adjustment is made pursuant to subsection (a) above or (d)
below) or subscription rights or warrants (excluding subscription rights or
warrants to purchase the class of Capital Stock into which Securities of such
series are convertible), the number of shares of such class of Capital Stock
into which each $1,000 principal amount of Securities of such series shall be
convertible after such record date shall be determined by multiplying the number
of shares of such class of Capital Stock into which such principal amount of
Securities was convertible immediately prior to such record date by a fraction,
of which the numerator shall be the fair market value of the assets of the
Issuer, after deducting therefrom all liabilities of the Issuer and all
preferences (including accrued but unpaid dividends) in respect of classes of
Capital Stock having a preference with respect to the assets of the Issuer over
such class of Capital Stock (all as determined by the Board of Directors, whose
determination shall be conclusive, and described in a certificate signed by any
vice chairmen of the board, vice president or assistant vice president and
treasurer of the Issuer, filed with the Trustee and each conversion agent) on
such record date, and of which the denominator shall be such fair market value
after deducting therefrom such liabilities and preferences, less the fair market
value (as determined by the Board of Directors, whose determination shall be
conclusive, and described in a statement filed with the Trustee and each
conversion agent) of the assets or evidences of indebtedness, so distributed or
of such subscription rights or warrants applicable, so distributed. Such
adjustment shall be made successively whenever such a record date is fixed; and
in the event that such distribution is not so made, the conversion rate shall
again be adjusted to the conversion rate which would then be in effect if such
record date had not been fixed.

     (d) In case the Issuer shall, by dividend or otherwise, distribute to all
holders of its Capital Stock cash (excluding (x) any quarterly cash dividend on
the Capital Stock to the extent the aggregate cash dividend per share of Capital
Stock in any fiscal quarter does not exceed the greater of (A) the amount per
share of Capital Stock of the next preceding quarterly cash dividend on the
Capital Stock to the extent such preceding quarterly dividend did not require
any adjustment of the conversion rate pursuant to this Section 12.05(d) (as
adjusted to reflect subdivisions or combinations of the Capital Stock), and (B)
3.75% of the current market price of the Capital Stock (determined as provided
in Section 12.05(e)) on the date of declaration of such dividend and (y) any
dividend or distribution in connection with the liquidation, dissolution or
winding up of the Issuer, whether voluntary or involuntary), then, in such case,
unless the Issuer elects to reserve such cash for distribution to the holders of
the Securities upon the conversion of the Securities so that any such holder
converting Securities will receive upon such conversion, in addition to the
shares of Capital Stock to which such holder is entitled, the amount of cash
which such holder would have received if such holder had, immediately prior to
the record date for such distribution of cash, converted its Securities into
Capital Stock, the conversion rate shall be adjusted so that the same shall
equal the rate determined by multiplying the conversion rate in effect
immediately prior to the record date by a fraction of which the denominator
shall be the current market price of the Capital Stock (determined as provided
in Section 12.05(e)) on the record date less the amount of cash so distributed
(and not excluded as provided above) applicable to one share of Capital Stock
and the numerator shall be such current market price of the Capital Stock
(determined as provided in Section 12.05(e)), such adjusted to be effective
immediately prior to the opening of business on the day following the record
date; provided, however, that in the event the portion of the cash so
distributed applicable to one share of Capital Stock is equal to or greater than
the current market price of the Capital Stock (determined as

                                       57
<PAGE>

provided in Section 12.05(e)) on the record date, in lieu of the foregoing
adjustment, adequate provision shall be made so that each Securityholder shall
have the right to receive upon conversion the amount of cash such holder would
have received had such holder converted each Security on the record date. If
such dividend or distribution is not so paid or made, the conversion rate shall
again be adjusted to be the conversion rate which would then be in effect if
such dividend or distribution had not been declared.

     (e) For the purpose of any computation under subsections (b) and (d) above
and Section 12.06, the current market price per share of the Capital Stock on
any date as of which such price is to be computed shall mean the average of the
Closing Prices for the 30 consecutive Business Days commencing 45 Business Days
before such date.

     (f) No adjustment in the conversion rate shall be required unless such
adjustment would require a cumulative increase or decrease of at least 1% in
such rate; provided, however, that any adjustments which by reason of this
subsection (e) are not required to be made shall be carried forward and taken
into account in any subsequent adjustment, and provided, further, that
adjustments shall be required and made in accordance with the provisions of this
Article 12 (other than this subsection (e)) not later than such time as may be
required in order to preserve the tax-free nature of a distribution for United
States income tax purposes to the holders of Securities or the class of Capital
Stock into which such Securities are convertible. All calculations under this
Article 12 shall be made to the nearest cent or to the nearest one-thousandth of
a share, as the case may be. Anything in this Section 12.05 to the contrary
notwithstanding, the Issuer shall be entitled to make such adjustments in the
conversion rate, in addition to those required by this Section 12.05, as it in
its discretion shall determine to be advisable in order that any stock dividend,
subdivision of shares, distribution of rights to purchase stock or securities,
or distribution of securities convertible into or exchangeable for stock
hereafter made by the Issuer to its shareholders shall not be taxable for United
States income tax purposes.

     (g) Whenever the conversion rate is adjusted, as herein provided, the
Issuer shall promptly file with the Trustee and with the office or agency
maintained by the Issuer for the conversion of Securities of such series
pursuant to Section 3.02, a certificate of a firm of independent public
accountants of recognized national standing selected by the Board of Directors
(who may be the regular accountants employed by the Issuer) setting forth the
conversion rate after such adjustment and setting forth a brief statement of the
facts requiring such adjustment and a computation thereof. Such certificate
shall be conclusive evidence of the correctness of such adjustment. Neither the
Trustee nor any conversion agent shall be under any duty or responsibility with
respect to any such certificate or any facts or computations set forth therein,
except to exhibit said certificate from time to time to any Securityholder of
such series desiring to inspect the same. The Issuer shall promptly cause a
notice setting forth the adjusted conversion rate to be mailed to the holders of
Securities of such series, as their names and addresses appear upon the register
of the Issuer.

     (h) In the event that at any time, as a result of shares of any other class
of Capital Stock becoming issuable in exchange or substitution for or in lieu of
shares of the class of Capital Stock into which such Securities are convertible
or as a result of an adjustment made pursuant to subsection (a) above, the
holder of any Security of such series thereafter surrendered for conversion
shall become entitled to receive any shares of the Issuer other than shares of
the class

                                       58
<PAGE>

of Capital Stock into which the Issuer of such series are convertible,
thereafter the number of such other shares so receivable upon conversion of any
Security shall be subject to adjustment from time to time in a manner and on
terms as nearly equivalent as practicable to the provisions with respect to the
class of Capital Stock into which the Securities of such series are convertible
contained in subsections (a) to (f), inclusive, above, and the provisions of
this Article 12 with respect to the class of Capital Stock into which the
Securities of such series are convertible shall apply on like terms to any such
other shares.

     (i) The conversion rate with respect to any Securities with original issue
discount, the terms of which provide for convertibility, shall not be adjusted
during the term of such Original Issue Discount Security for accrued original
issue discount.

     (j) In the event that the Securities of any series are convertible into
more than one class of Capital Stock, the provisions of this Section 12.05 shall
apply separately to events affecting each such class.

     Section 12.06. No Fractional Shares to Be Issued. No fractional shares of
Capital Stock shall be issued upon conversions of Securities. If more than one
Security of any series shall be surrendered for conversion at one time by the
same holder, the number of full shares which shall be issuable upon conversion
thereof shall be computed on the basis of the aggregate principal amount of the
Securities of such series (or specified portions thereof to the extent permitted
hereby) so surrendered. Instead of a fraction of a share of Capital Stock which
would otherwise be issuable upon conversion of any Security or Securities (or
specified portions thereof), the Issuer shall pay a cash adjustment in respect
of such fraction of a share in an amount equal to the same fractional interest
of the current market price (as defined in Section 12.05) per share of Capital
Stock on the Business Day next preceding the day of conversion.

     Section 12.07. Preservation of Conversion Rights Upon Consolidation,
Merger, Sale or Conveyance. In case of any consolidation of the Issuer with, or
merger of the Issuer into, any other corporation (other than a consolidation or
merger in which the Issuer is the continuing corporation), or in the case of any
sale or transfer of all or substantially all of the assets of the Issuer, the
corporation formed by such consolidation or the corporation into which the
Issuer shall have been merged or the corporation which shall have acquired such
assets, as the case may be, shall execute and deliver to the Trustee, a
supplemental indenture, subject to the provisions of Articles 7 and 8 as they
relate to supplemental indentures, providing that the holder of each Security
then Outstanding of a series which was convertible into Capital Stock shall have
the right thereafter to convert such Security into the kind and amount of shares
of stock and other securities and property, including cash, receivable upon such
consolidation, merger, sale or transfer by a holder of the number of shares of
Capital Stock of the Issuer into which such Securities might have been converted
immediately prior to such consolidation, merger, sale or transfer. Such
supplemental indenture shall conform to the provisions of the Trust Indenture
Act of 1939 as then in effect and shall provide for adjustments which shall be
as nearly equivalent as may be practicable to the adjustments provided for in
this Article 12. Neither the Trustee nor any conversion agent shall be under any
responsibility to determine the correctness of any provision contained in any
such supplemental indenture relating either to the kind or amount of shares of
stock or other securities or property receivable by Securityholders upon the
conversion of their Securities after any such consolidation, merger, sale or
transfer, or to any adjustment to be made with respect there to and, subject to
the provisions of Article 5, may accept as conclusive

                                       59

evidence of the correctness of any such provisions, and shall be protected in
relying upon, an Opinion of Counsel with respect thereto. If in the case of any
such consolidation, merger, sale or transfer, the stock or other securities and
property receivable by a holder of the Securities includes stock or other
securities and property of a corporation other than the successor or purchasing
corporation, then such supplemental indenture shall also be executed by such
other corporation and shall contain such additional provisions to protect the
interests of the holders of the Securities as the Board of Directors shall
reasonably consider necessary. The above provisions of this Section 12.07 shall
similarly apply to successive consolidations, mergers, sales or transfers.

     Section 12.08. Notice to Security Holders of a Series Prior to Taking
Certain Types of Action. With respect to the Securities of any series, in case:

     (a) the Issuer shall authorize the issuance to all holders of the class of
Capital Stock into which Securities of such series are convertible of rights or
warrants to subscribe for or purchase shares of its Capital Stock or of any
other right;

     (b) the Issuer shall authorize the distribution to all holders of the class
of Capital Stock into which Securities of such series are convertible of
evidences of its indebtedness or assets (except for the exclusions with respect
to certain dividends set forth in Section 12.05(c));

     (c) of any subdivision, combination or reclassification of the class of
Capital Stock into which Securities of such series are convertible or of any
consolidation or merger to which the Issuer is a party and for which approval by
the shareholders of the Issuer is required, or of the sale or transfer of all or
substantially all of the assets of the Issuer; or

     (d) of the voluntary or involuntary dissolution, liquidation or winding up
of the Issuer;

then the Issuer shall cause to be filed with the Trustee and at the office or
agency maintained for the purpose of conversion of Securities of such series
pursuant to Section 3.02, and shall cause to be mailed to the holders of
Securities of such series, at their last addresses as they shall appear upon the
register of the Issuer, at least ten days prior to the applicable record date
hereinafter specified, a notice stating Error! Bookmark not defined. the date as
of which the holders of such class of Capital Stock to be entitled to receive
any such rights, warrants or distribution are to be determined, or Error!
Bookmark not defined. the date on which any such subdivision, combination,
reclassification, consolidation, merger, sale, transfer, dissolution,
liquidation, winding up or other action is expected to become effective, and the
date as of which it is expected that holders of record of such class of Capital
Stock shall be entitled to exchange their Capital Stock of such class for
securities or other property, if any, deliverable upon such subdivision,
combination, reclassification, consolidation, merger, sale, transfer,
dissolution, liquidation, winding up or other action. The failure to give the
notice required by this Section 12.08 or any defect therein shall not affect the
legality or validity of any distribution, right, warrant, subdivision,
combination, reclassification, consolidation, merger, sale, transfer,
dissolution, liquidation, winding up or other action, or the vote upon any of
the foregoing. Such notice shall also be published by and at the expense of the
Issuer not later than the aforesaid filing date at least once in an Authorized
Newspaper.

     Section 12.09. Covenant to Reserve Shares for Issuance on Conversion of
Securities. The Issuer covenants that at all times it will reserve and keep
available out of each class of its

                                       60
<PAGE>

authorized Capital Stock, free from preemptive rights, solely for the purpose of
issue upon conversion of Securities of any series as herein provided, such
number of shares of Capital Stock of such class as shall then be issuable upon
the conversion of all Outstanding Securities of such series. The Issuer
covenants that an shares of Capital Stock which shall be so issuable shall, when
issued or delivered, be duly and validly issued shares of the class of
authorized Capital Stock into which Securities of such series are convertible,
and shall be fully paid and nonassessable, free of all liens and charges and not
subject to preemptive rights and that, upon conversion, the appropriate capital
stock accounts of the Issuer will be duly credited.

     Section 12.10. Compliance with Governmental Requirements. The Issuer
covenants that if any shares of Capital Stock required to be reserved for
purposes of conversion of Securities hereunder require registration or listing
with or approval of any governmental authority under any Federal or State law,
pursuant to the Securities Act of 1933, as amended, or the Securities Exchange
Act of 1934, as amended, or any national or regional securities exchange on
which such Capital Stock is listed at the time of delivery of any shares of such
Capital Stock, before such shares may be issued upon conversion, the Issuer will
use its best efforts to cause such shares to be duly registered, listed or
approved, as the case may be.

     Section 12.11. Payment of Taxes Upon Certificates for Shares Issued Upon
Conversion. The issuance of certificates for shares of Capital Stock upon the
conversion of Securities shall be made without charge to the converting
Securityholders for any tax (including, without limitation, all documentary and
stamp taxes) in respect of the issuance and delivery of such certificates, and
such certificates shall be issued in the respective names of, or in such names
as may be directed by, the holders of the Securities converted; provided,
however, that the Issuer shall not be required to pay any tax which may be
payable in respect of any transfer involved in the issuance and delivery of any
such certificate in a name other than that of the holder of the Security
converted, and the Issuer shall not be required to issue or deliver such
certificates unless or until the person or persons requesting the issuance
thereof shall have paid to the Issuer the amount of such tax or shall have
established to the satisfaction of the Issuer that such tax has been paid.

     Section 12.12. Trustee's Duties with Respect to Conversion Provisions. The
Trustee and any conversion agent shall not at any time be under any duty or
responsibility to any Securityholder to determine whether any facts exist which
may require any adjustment of the conversion rate or conversion price, or with
respect to the nature or extent of any such adjustment when made, or with
respect to the method employed, or herein or in any supplemental indenture
provided to be employed, in making the same. Neither the Trustee nor any
conversion agent shall be accountable with respect to the registration under
securities laws, listing, validity or value (or the kind or amount) of any
shares of Capital Stock, or of any other securities or property, which may at
any time be issued or delivered upon the conversion of any Security; and neither
the Trustee nor any conversion agent makes any representation with respect
thereto. Neither the Trustee nor any conversion agent shall be responsible for
any failure of the Issuer to make any cash payment or to issue, transfer or
deliver any shares of stock or stock certificates or other securities or
property upon the surrender of any Security for the purpose of conversion; and
the Trustee, subject to the provisions of Article 5, and any conversion agent
shall not be responsible for any failure of the Issuer to comply with any of the
covenants of the Issuer contained in this Article 12.

                                   GUARANTEES

     Section 13.01. The Cable Guarantees. Subject to the provisions of this
Article, each Cable Guarantor hereby irrevocably, fully and unconditionally
guarantees, jointly and severally, on an unsecured basis, the full and punctual
payment (whether at maturity, upon redemption, or otherwise) of the Principal of
and interest on, and all other amounts payable under, each Security, and the
full and punctual payment of all other amounts payable by the Issuer under the
Indenture. Upon failure by the Issuer to pay punctually any such amount, each
Cable Guarantor shall forthwith on demand pay the amount not so paid at the
place and in the manner specified in the Indenture.

     Section 13.02. Guarantee Unconditional. The obligations of each Cable
Guarantor hereunder are unconditional and absolute and, without limiting the
generality of the foregoing, will not be released, discharged or otherwise
affected by

     (a) any extension, renewal, settlement, compromise, waiver or release in
respect of any obligation of the Issuer under the Indenture or any Security, by
operation of law or otherwise;

     (b) any modification or amendment of or supplement to the Indenture or any
Security;

     (c) any change in the corporate existence, structure or ownership of the
Issuer, or any insolvency, bankruptcy, reorganization or other similar
proceeding affecting the Issuer or its assets or any resulting release or
discharge of any obligation of the Issuer contained in the Indenture or any
Security;

     (d) the existence of any claim, set-off or other rights which any Cable
Guarantor may have at any time against the Issuer, the Trustee, any other Cable
Guarantor or any other Person, whether in connection with the Indenture or an
unrelated transactions, provided that nothing herein prevents the assertion of
any such claim by separate suit or compulsory counterclaim;

     (e) any invalidity, irregularity or unenforceability relating to or against
the Issuer for any reason of the Indenture or any Security, or any provision of
applicable law or regulation purporting to prohibit the payment by the Issuer of
the principal of or interest on any Security or any other amount payable by the
Issuer under the Indenture; or

     (f) any other act or omission to act or delay of any kind by the Issuer,
the Trustee or any other Person or any other circumstance whatsoever which
might, but for the provisions of this paragraph, constitute a legal or equitable
discharge of or defense to such Cable Guarantor's obligations hereunder.

     Section 13.03. Discharge; Reinstatement. Each Cable Guarantor's obligations
hereunder will remain in full force and effect until the Principal of and
interest on the Securities of each series and all other amounts payable by the
Issuer under the Indenture have been paid in full. If at any time any payment of
the Principal of or interest on any Security or any other amount payable by the
Issuer under the Indenture is rescinded or must be otherwise restored or
returned upon the insolvency, bankruptcy or reorganization of the Issuer or
otherwise, each Cable

                                       62
<PAGE>

Guarantor's obligations hereunder with respect to such payment will be
reinstated as though such payment had been due but not made at such time.

     Section 13.04. Waiver by the Cable Guarantors. Each Cable Guarantor
irrevocably waives acceptance hereof, presentment, demand, protest and any
notice not provided for herein, as well as any requirement that at any time any
action be taken by any Person against the Company or any other Person.

     Section 13.05. Subrogation and Contribution. Upon making any payment with
respect to any obligation of the Issuer under this Article, the Cable Guarantor
making such payment will be subrogated to the rights of the payee against the
Issuer with respect to such obligation, provided that the Cable Guarantor may
not enforce either any right of subrogation, or any right to receive payment in
the nature of contribution, or otherwise, from any other Cable Guarantor, with
respect to such payment so long as any amount payable by the Issuer hereunder or
under the Securities remains unpaid.

     Section 13.06. Stay of Acceleration. If acceleration of the time for
payment of any amount payable by the Issuer under the Indenture or the
Securities is stayed upon the insolvency, bankruptcy or reorganization of the
Issuer, all such amounts otherwise subject to acceleration under the terms of
the Indenture are nonetheless payable by the Cable Guarantors hereunder
forthwith on demand by the Trustee or the Holders.

     Section 13.07. Limitation on Amount of Cable Guarantee. Notwithstanding
anything to the contrary in this Article, each Cable Guarantor, and by its
acceptance of Securities, each Holder, hereby confirms that it is the intention
of all such parties that the Cable Guarantee of such Cable Guarantor not
constitute a fraudulent conveyance under applicable fraudulent conveyance
provisions of the United States Bankruptcy Code or any comparable provision of
other U.S. and non-U.S. law. To effectuate that intention, the Trustee, the
Holders and the Cable Guarantors hereby irrevocably agree that the obligations
of each Cable Guarantor under its Cable Guarantee are limited to the maximum
amount that would not render the Cable Guarantor's obligations subject to
avoidance under applicable fraudulent conveyance provisions of the United States
Bankruptcy Code or any comparable provision of other U.S. and non-U.S. law.

     Section 13.08. Execution and Delivery of Cable Guarantee. The execution by
each Cable Guarantor of the Indenture evidences the Cable Guarantee of such
Cable Guarantor, whether or not the person signing as an officer of the Cable
Guarantor still holds that office at the time of authentication of any Security.
The delivery of any Security by the Trustee after authentication constitutes due
delivery of the Cable Guarantee set forth in the Indenture on behalf of each
Cable Guarantor.

     Section 13.09. Release of Cable Guarantee. This Cable Guarantee of a Cable
Guarantor will terminate upon

     (a) A sale or other disposition (including by way of consolidation or
merger) of the Cable Guarantor or the sale or disposition of all or
substantially all the assets of the Cable Guarantor (in each case other than to
the Issuer or a Cable Guarantor or a Person who, prior to such sale or other
disposition, is an affiliate of the Issuer or a Cable Guarantor); or

                                       63
<PAGE>

     (b) Defeasance or discharge of the Securities, as provided in Article 9.
Upon delivery by the Issuer to the Trustee of an Officers' Certificate and an
Opinion of Counsel to the foregoing effect, the Trustee will execute any
documents reasonably required in order to evidence the release of the Cable
Guarantor from its obligations under its Cable Guarantee.

by both (a) the chairman of its Board of Directors, or any vice chairman of its
Board of Directors, or its president or any vice president and (b) by its
treasurer or any assistant treasurer, without any further action by the Issuer.
In authenticating such Securities and accepting the additional responsibilities

and (subject to Section 5.01) shall be fully protected in relying upon:

<PAGE>

          (b) a copy of any resolution or resolutions of the Board of Directors
     relating to such series, in each case certified by the secretary or an
     assistant secretary of the Issuer;

          (c) an executed supplemental indenture, if any, and the documentation
     required to be delivered pursuant to Section 7.04;

          (d) an Officers' Certificate setting forth the form and terms of the
     Securities as required pursuant to Section 2.01 and 2.03, respectively and
     prepared in accordance with Section 10.05;

          (e) an Opinion of Counsel, prepared in accordance with Section 10.05,
     to the effect

               (i) that the form or forms and terms of such Securities have been
          established by or pursuant to a resolution of the Board of Directors
          or by a supplemental indenture as permitted by Section 2.01 and 2.03
          in conformity with the provisions of this Indenture; and

               (ii) that such Securities, when authenticated and delivered by
          the Trustee and issued by the Issuer in the manner and subject to any
          conditions specified in such Opinion of Counsel, will constitute
          legal, valid and binding obligations of the Issuer enforceable against
          the Issuer in accordance with their terms.

     The Trustee shall have the right to decline to authenticate and deliver any
Securities under this section if the Trustee, being advised by counsel,
determines that such action may not lawfully be taken by the Issuer or if the
Trustee in good faith by its board of directors or board of trustees, executive
committee, or a trust committee of directors or trustees or Responsible Officers
shall determine that such action would expose the Trustee to personal liability.

     If the Issuer shall establish pursuant to Section 2.03 that the Securities
of a series or a portion thereof are to be issued in the form of one or more
Registered Global Securities, then the Issuer shall execute (in accordance with
Section 2.05) and the Trustee shall authenticate and make available for delivery
one or more Registered Global Securities that (i) shall represent and shall be
denominated in an amount equal to the aggregate principal amount of all of the
Securities of such series issued in such form and not yet canceled, (ii) shall
be registered in the name of the Depositary for such Registered Global Security
or Securities or the nominee of such Depositary, (iii) shall be delivered by the
Trustee to such Depositary or its custodian or pursuant to such Depositary's
instructions and (iv) shall bear a legend substantially to the following effect:
"Unless and until it is exchanged in whole or in part for Securities in
definitive registered form, this

                                       15
<PAGE>

Security may not be transferred except as a whole by the Depositary to a nominee
of the Depositary or by a nominee of the Depositary to the Depositary or another
nominee of the Depositary or by the Depositary or any such nominee to a
successor Depositary or a nominee of such successor Depositary."

     Section 2.05. Execution of Securities. The Securities shall be signed on
behalf of the Issuer by the chairman of its Board of Directors or any vice
chairman of its Board of Directors or its president or any vice president or its
treasurer or any assistant treasurer, under its corporate seal and attested by
its secretary or any assistant secretary. Such signatures may be the manual or
facsimile signatures of the present or any future such officers. The seal of the
Issuer may be in the form of a facsimile thereof and may be impressed, affixed,
imprinted or otherwise reproduced on the Securities. Typographical and other
minor errors or defects in any such reproduction of the seal or any such
signature shall not affect the validity or enforceability of any Security that
has been duly authenticated and delivered by the Trustee.

     In case any officer of the Issuer who shall have signed any of the
Securities shall cease to be such officer before the Security so signed shall be
authenticated and delivered by the Trustee or disposed of by the Issuer, such
Security nevertheless may be authenticated and delivered or disposed of as
though the person who signed such Security had not ceased to be such officer of
the Issuer; and any Security may be signed on behalf of the Issuer by such
persons as, at the actual date of the execution of such Security, shall be the
proper officers of the Issuer, although at the date of the execution and
delivery of this Indenture any such person was not such an officer.

     Section 2.06. Certificate of Authentication. Only such Securities as shall
bear thereon a certificate of authentication substantially in the form
hereinbefore recited, executed by the Trustee by the manual signature of one of
its authorized signatories, shall be entitled to the benefits of this Indenture
or be valid or obligatory for any purpose. Such certificate by the Trustee upon
any Security executed by the Issuer shall be conclusive evidence that the
Security so authenticated has been duly authenticated and delivered hereunder
and that the holder is entitled to the benefits of this Indenture.

     Section 2.07. Denomination and Date of Securities; Payments of Interest.
The Securities shall be issuable as registered securities without coupons and in
denominations as shall be specified as contemplated by Section 2.03. In the
absence of any such specification with respect to the Securities of any series,
the Securities of such series shall be issuable in denominations of $1,000 and
any multiple thereof. The Securities shall be numbered, lettered, or otherwise
distinguished in such manner or in accordance with such plan as the officers of
the Issuer executing the same may determine as evidenced by the execution and
authentication thereof.

                                       16
<PAGE>

     Each Security shall be dated the date of its authentication, shall bear
interest, if any, from the date and shall be payable on the dates, in each case,
which shall be specified as contemplated by Section 2.03.

     The person in whose name any Security of any series is registered at the
close of business on any record date applicable to a particular series with
respect to any interest payment date for such series shall be entitled to
receive the interest, if any, payable on such interest payment date
notwithstanding any transfer or exchange of such Security subsequent to the
record date and prior to such interest payment date, except if and to the extent
the Issuer shall default in the payment of the interest due on such interest
payment date for such series, in which case such defaulted interest shall be
paid to the persons in whose names Outstanding Securities for such series are
registered at the close of business on a subsequent record date (which shall be
not less than five Business Days prior to the date of payment of such defaulted
interest) established by notice given by mail by or on behalf of the Issuer to
the holders of Securities not less than 15 days preceding such subsequent record
date. The term "record date" as used with respect to any interest payment date
(except a date for payment of defaulted interest) shall mean the date specified
as such in the terms of the Securities of any particular series, or, if no such
date is so specified, if such interest payment date is the first day of a
calendar month, the fifteenth day of the next preceding calendar month or, if
such interest payment date is the fifteenth day of a calendar month, the first
day of such calendar month, whether or not such record date is a Business Day.

     Section 2.08. Registration, Transfer and Exchange. The Issuer will keep or
cause to be kept at each office or agency to be maintained for the purpose as
provided in Section 3.02 a register or registers in which, subject to such
reasonable regulations as it may prescribe, it will register, and will register
the transfer of, Securities as in this Article provided. Such register shall be
in written form in the English language or in any other form capable of being
converted into such form within a reasonable time. At all reasonable times such
register or registers shall be open for inspection by the Trustee.

     At the option of the Holder thereof, Registered Securities of any series
(other than a Registered Global Security, except as set forth below) may be
exchanged for a Registered Security or Registered Securities of such series and
tenor having authorized denominations and an equal aggregate principal amount,
upon surrender of such Registered Securities to be exchanged at the agency of
the Issuer that shall be maintained for such purpose in accordance with Section
3.02 and upon payment, if the Issuer shall so require, of the charges
hereinafter provided. If the Securities of any series are issued in both
registered and unregistered form, except as otherwise established pursuant to
Section 2.03, at the option of the Holder thereof, Unregistered Securities of
any series may be exchanged for Registered Securities of such series and tenor
having authorized denominations and an equal aggregate principal amount, upon
surrender of such

                                       17
<PAGE>

Unregistered Securities to be exchanged at the agency of the Issuer that shall
be maintained for such purpose in accordance with Section 3.02 and upon payment,
if the Issuer shall so require, of the charges hereinafter provided. At the
option of the Holder thereof, if Unregistered Securities of any series, maturity
date, interest rate and original issue date are issued in more than one
authorized denomination, except as otherwise established pursuant to Section
2.03, such Unregistered Securities may be exchanged for Unregistered Securities
of such series and tenor having authorized denominations and an equal aggregate
principal amount, upon surrender of such Unregistered Securities to be exchanged
at the agency of the Issuer that shall be maintained for such purpose in
accordance with Section 3.02 and upon payment, if the Issuer shall so require,
of the charges hereinafter provided. Registered Securities of any series may not
be exchanged for Unregistered Securities of such series. Whenever any Securities
are so surrendered for exchange, the Issuer shall execute, and the Trustee shall
authenticate and make available for delivery, the Securities which the Holder
making the exchange is entitled to receive.

     All Registered Securities presented for registration of transfer, exchange,
redemption, conversion or payment shall be duly endorsed by, or be accompanied
by a written instrument or instruments of transfer in form satisfactory to the
Issuer and the Trustee duly executed by, the holder or his attorney duly
authorized in writing.

     The Issuer may require payment of a sum sufficient to cover any tax or
other governmental charge that may be imposed in connection with any exchange or
registration of transfer of Securities. No service charge shall be made for any
such transaction.

     Notwithstanding any other provision of this Section 2.08, unless and until
it is exchanged in whole or in part for Securities in definitive registered
form, a Registered Global Security representing all or a portion of the
Securities of a series may not be transferred except as a whole by the
Depositary for such series to a nominee of such Depositary or by a nominee of
such Depositary to such Depositary or another nominee of such Depositary or by
such Depositary or any such nominee to a successor Depositary for such series or
a nominee of such successor Depositary.

     If at any time the Depositary for any Registered Global Securities of any
series notifies the Issuer that it is unwilling or unable to continue as
Depositary for such Registered Global Securities or if at any time the
Depositary for such Registered Global Securities shall no longer be eligible
under applicable law, the Issuer shall appoint a successor Depositary eligible
under applicable law with respect to such Registered Global Securities. If a
successor Depositary eligible under applicable law for such Registered Global
Securities is not appointed by the Issuer within 90 days after the Issuer
receives such notice or becomes aware of

                                       18
<PAGE>

such ineligibility, the Issuer will execute, and the Trustee, upon receipt of
the Issuer's order for the authentication and delivery of definitive Registered
Securities of such series and tenor, will authenticate and make available for
delivery Registered Securities of such series and tenor, in any authorized
denominations, in an aggregate principal amount equal to the principal amount of
such Registered Global Securities, in exchange for such Registered Global
Securities.

     The Issuer may at any time and in its sole discretion determine that any
Registered Global Securities of any series shall no longer be maintained in
global form. In such event, or in the event that there shall have occurred and
be continuing an Event of Default with respect to a series of Securities, the
Issuer will, upon the request of any Holder, execute, and the Trustee, upon
receipt of the Issuer's order for the authentication and delivery of definitive
Registered Securities of such series and tenor, will authenticate and make
available for delivery, Registered Securities of such series and tenor in any
authorized denominations, in an aggregate principal amount equal to the
principal amount of such Registered Global Securities, in exchange for such
Registered Global Securities.

     Any time the Registered Securities of any series are not in the form of
Registered Global Securities pursuant to the preceding two paragraphs, the
Issuer agrees to supply the Trustee with a reasonable supply of certificated
Registered Securities without the legend required by Section 2.04 and the
Trustee agrees to hold such Registered Securities in safekeeping until
authenticated and delivered pursuant to the terms of this Indenture.

     If established by the Issuer pursuant to Section 2.03 with respect to any
Registered Global Security, the Depositary for such Registered Global Security
may surrender such Registered Global Security in exchange in whole or in part
for Registered Securities of the same series and tenor in definitive registered
form on such terms as are acceptable to the Issuer and such Depositary.
Thereupon, the Issuer shall execute, and the Trustee shall authenticate and make
available for delivery, without service charge,

          (i) to the Person specified by such Depositary new Registered
     Securities of the same series and tenor, of any authorized denominations as
     requested by such Person, in an aggregate principal amount equal to and in
     exchange for such Person's beneficial interest in the Registered Global
     Security; and

          (ii) to such Depositary a new Registered Global Security in a
     denomination equal to the difference, if any, between the principal amount
     of the surrendered Registered Global Security and the aggregate principal

                                       19
<PAGE>

     amount of Registered Securities authenticated and delivered pursuant to
     clause (i) above.

     Registered Securities issued in exchange for a Registered Global Security
pursuant to this Section 2.08 shall be registered in such names and in such
authorized denominations as the Depositary for such Registered Global Security,
pursuant to instructions from its direct or indirect participants or otherwise,
shall instruct the Trustee or an agent of the Issuer or the Trustee. The Trustee
or such agent shall deliver such Securities to or as directed by the Persons in
whose names such Securities are so registered.

     All Securities issued upon any transfer or exchange of Securities shall be
valid obligations of the Issuer, evidencing the same debt, and entitled to the
same benefits under this Indenture, as the Securities surrendered upon such
transfer or exchange.

     Notwithstanding anything herein or in the forms or terms of any Securities
to the contrary, none of the Issuer, the Trustee or any agent of the Issuer or
the Trustee shall be required to exchange any Unregistered Security for a
Registered Security if such exchange would result in adverse Federal income tax
consequences to the Issuer (such as, for example, the inability of the Issuer to
deduct from its income, as computed for Federal income tax purposes, the
interest payable on the Unregistered Securities) under then applicable United
States Federal income tax laws. The Trustee and any such agent shall be entitled
to rely on an Officers' Certificate or an Opinion of Counsel in determining such
result.

     Neither the Registrar nor the Issuer shall be required (i) to issue,
authenticate, register the transfer of or exchange Securities of any series for
a period of 15 days before the mailing of a notice of redemption of such
Securities to be redeemed or (ii) to register the transfer of or exchange any
Security selected for redemption in whole or in part.

     Section 2.09. Mutilated, Defaced, Destroyed, Lost and Stolen Securities. In
case any temporary or definitive Security shall become mutilated or defaced and
shall be surrendered to the Trustee, the Issuer shall execute, and the Trustee
shall authenticate and deliver, a new Security of the same series, bearing a
number not contemporaneously outstanding, in exchange and substitution for the
mutilated or defaced Security. If the Holder of any Security claims that the
Security has been lost, destroyed or wrongfully taken, the Issuer shall execute,
and the Trustee shall authenticate and deliver, a new Security of the same
series, bearing a number not contemporaneously outstanding, in exchange and
substitution for the lost, destroyed or wrongfully taken Security, if the
applicant so requests before the Issuer has notice that the Security has been
acquired by a protected purchaser, and the applicant furnishes to the Issuer and
to the Trustee and any agent of the Issuer or the Trustee such security or
indemnity as may be

                                       20
<PAGE>

required by them to indemnify and defend and to save each of them harmless and
the applicant satisfies other reasonable requirements imposed by the Issuer.

     Upon the issuance of any substitute Security, the Issuer may require the
payment of a sum sufficient to cover any tax or other governmental charge that
may be imposed in relation thereto and any other expenses (including the fees
and expenses of the Trustee and its counsel) connected therewith. In case any
Security which has matured or is about to mature or has been called for
redemption in full shall become mutilated or defaced or be destroyed, lost or
stolen, the Issuer may instead of issuing a substitute Security, pay or
authorize the payment of the same (without surrender thereof except in the case
of a mutilated or defaced Security), if the applicant for such payment shall
furnish to the Issuer and to the Trustee and any agent of the Issuer or the
Trustee such security or indemnity as any of them may require to save each of
them harmless, and, in every case of destruction, loss or wrongful taking, the
applicant shall also furnish to the Issuer and the Trustee and any agent of the
Issuer or the Trustee evidence to their satisfaction of the destruction, loss or
wrongful taking of such Security and of the ownership thereof.

     Every substitute Security of any series issued pursuant to the provisions
of this section by virtue of the fact that any such Security is destroyed, lost
or stolen shall constitute an additional contractual obligation of the Issuer,
whether or not the destroyed, lost or wrongfully taken Security shall be at any
time enforceable by anyone and shall be entitled to all the benefits of (but
shall be subject to all the limitations of rights set forth in) this Indenture
equally and proportionately with any and all other Securities of such series
duly authenticated and delivered hereunder. All Securities shall be held and
owned upon the express condition that, to the extent permitted by law, the
foregoing provisions are exclusive with respect to the replacement or payment of
mutilated, defaced or destroyed, lost or wrongfully taken Securities and shall
preclude any and all other rights or remedies.

     Section 2.10. Cancellation of Securities; Destruction Thereof. All
Securities surrendered for payment, redemption, conversion, registration of
transfer or exchange, or for credit against any payment in respect of a sinking
or analogous fund, if surrendered to the Issuer or any agent of the Issuer or
the Trustee, shall be delivered to the Trustee for cancellation or, if
surrendered to the Trustee, shall be canceled by it; and no Securities shall be
issued in lieu thereof except as expressly permitted by any of the provisions of
this Indenture. The Trustee shall dispose of canceled Securities held by it in
accordance with the record retention policies of the Trustee in effect from time
to time and, if such canceled certificates are destroyed, shall deliver a
certificate of destruction to the Issuer. If the Issuer shall acquire any of the
Securities, such acquisition shall not operate as a redemption or satisfaction
of the indebtedness represented by such Securities unless and until the same are
delivered to the Trustee for cancellation.

                                       21

     Section 2.11. Temporary Securities. Pending the preparation of definitive
Securities for any series, the Issuer may execute and the Trustee shall
authenticate and deliver temporary Securities for such series (printed,
lithographed, typewritten or otherwise reproduced, in each case in form
satisfactory to the Trustee). Temporary Securities of any series shall be
issuable as registered Securities without coupons, of any authorized
denomination, and substantially in the form of the definitive Securities of such
series but with such omissions, insertions and variations as may be appropriate
for temporary Securities, all as may be determined by the Issuer with the
concurrence of the Trustee. Temporary Securities may contain such reference to
any provisions of this Indenture as may be appropriate. Every temporary Security
shall be executed by the Issuer and be authenticated by the Trustee upon the
same conditions and in substantially the same manner, and with like effect, as
the definitive Securities. Without unreasonable delay the Issuer shall execute
and shall furnish definitive Securities of such series and thereupon temporary
Securities of such series may be surrendered in exchange therefor without charge
at each office or agency to be maintained by the Issuer for that purpose
pursuant to Section 3.02, and the Trustee shall authenticate and deliver in
exchange for such temporary Securities of such series a like aggregate principal
amount of definitive Securities of the same series of authorized denominations.
Until so exchanged, the temporary Securities of any series shall be entitled to
the same benefits under this Indenture as definitive Securities of such series.

     Section 2.12. Computation of Interest. Except as otherwise specified in the
Securities of a series, interest shall be computed on the basis of a 360-day
year of twelve 30-day months.

     Section 2.13. Cusip Numbers. The Issuer in issuing the Securities 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 Securities or as contained
in any notice of a redemption and that reliance may be placed only on the other
identification numbers printed on the Securities, and any such redemption shall
not be affected by any defect in or omission of such numbers. The Issuer will
notify the Trustee of any change in the "CUSIP" numbers.

                                   Article 3
          COVENANTS OF THE ISSUER, THE CABLE GUARANTORS AND THE TRUSTEE

     Section 3.01. Payment of Principal and Interest. The Issuer covenants and
agrees for the benefit of each series of Securities that it will duly and
punctually pay or cause to be paid the principal of, and interest on, each of
the Securities of such series at the place or places, at the respective times
and in the

                                       22
<PAGE>

manner provided in such Securities. Each installment of interest on the
Securities of any series may be paid by mailing checks for such interest payable
to or upon the written order of the holders of Securities entitled thereto as
they shall appear on the registry books of the Issuer.

     Notwithstanding any provisions of this Indenture and the Securities of any
series to the contrary, if the Issuer and a Holder of any Registered Security so
agree or if expressly provided pursuant to Section 2.03, payments of interest
on, and any portion of the Principal of, such Holder's Registered Security
(other than interest payable at maturity or on any redemption or repayment date
or the final payment of Principal on such Security) shall be made by the paying
agent, upon receipt from the Issuer of immediately available funds by 11:00
a.m., New York City time (or such other time as may be agreed to between the
Issuer and the paying agent) or the Issuer, directly to the Holder of such
Security (by wire transfer of Federal funds or immediately available funds or
otherwise) if the Holder has delivered written instructions to the Trustee 15
days prior to such payment date requesting that such payment will be so made and
designating the bank account to which such payments shall be so made and, in the
case of payments of Principal, surrenders the same to the Trustee in exchange
for a Security or Securities aggregating the same principal amount as the
unredeemed principal amount of the Securities surrendered. The Trustee shall be
entitled to rely on the last instruction delivered by the Holder pursuant to
this Section 3.01 unless a new instruction is delivered 15 days prior to a
payment date. The Issuer will indemnify and hold each of the Trustee and any
paying agent harmless against any loss, liability or expense (including
attorneys' fees and expenses) resulting from any act or omission to act on the
part of the Issuer or any such Holder in connection with any such agreement or
from making any payment in accordance with any such agreement.

     Section 3.02. Offices for Payments, etc. So long as any of the Securities
remain outstanding, the Issuer will maintain in the Borough of Manhattan, The
City of New York an office or agency (a) where the Securities may be presented
for payment, (b) where the Securities may be presented for registration of
transfer and for exchange as in this Indenture provided, (c) where notices and
demands to or upon the Issuer in respect of the Securities or of this Indenture
may be served and (d) for Securities of each series that is convertible, where
such Securities may be presented for conversion. The Issuer will give to the
Trustee written notice of the location of any such office or agency and of any
change of location thereof. Unless otherwise specified in accordance with
Section 2.03, the Issuer hereby initially designates the Corporate Trust Office
of Trustee as the office to be maintained by it for each such purpose. In case
the Issuer shall fail to so designate or maintain any such office or agency or
shall fail to give such notice of the location or of any change in the location
thereof, presentations and demands may be made and notices may be served at the
Corporate Trust Office.

                                       23

     Section 3.03. Paying Agents. Whenever the Issuer shall appoint a paying
agent other than the Trustee with respect to the Securities of any series, it
will cause such paying agent to execute and deliver to the Trustee an instrument
in which such agent shall agree with the Trustee, subject to the provisions of
this Section,

          (a) that it will hold all sums received by it as such agent for the
     payment of the principal of or interest on the Securities of such series
     (whether such sums have been paid to it by the Issuer or by any other
     obligor on the Securities of such series) in trust for the benefit of the
     holders of the Securities of such series or of the Trustee,

          (b) that it will give the Trustee notice of any failure by the Issuer
     (or by any other obligor on the Securities of such series) to make any
     payment of the principal of or interest on the Securities of such series
     when the same shall be due and payable, and

          (c) that it will pay any such sums so held in trust by it to the
     Trustee upon the Trustee's written request at any time during the
     continuance of the failure referred to in clause 3.03(b) above.

     The Issuer will, on or prior to each due date of the principal of or
interest on the Securities of such series, deposit with the paying agent a sum
sufficient to pay such principal or interest so becoming due, and (unless such
paying agent is the Trustee) the Issuer will promptly notify the Trustee of any
failure to take such action.

     If the Issuer shall act as its own paying agent with respect to the
Securities of any Series, it will, on or before each due date of the principal
of or interest on the Securities of such series, set aside, segregate and hold
in trust for the benefit of the holders of the Securities of such series a sum
sufficient to pay such principal or interest so becoming due. The Issuer will
promptly notify the Trustee of any failure to take such action.

     Whenever the Issuer shall have one or more paying agents for any series of
Securities, it will, on or before each due date of the principal of or interest
on any Securities of such series, deposit with the paying agent or agents for
the Securities of such series a sum, by 10:00 a.m. New York City time in
immediately available funds on the payment date, sufficient to pay the principal
or interest so becoming due with respect to the Securities of such series, and
(unless such paying agent is the Trustee) the Issuer will promptly notify the
Trustee in writing of any failure so to act.

     Anything in this section to the contrary notwithstanding, the Issuer may at
any time, for the purpose of obtaining a satisfaction and discharge with respect
to

                                       24
<PAGE>

one or more or all series of Securities hereunder, or for any other reason, pay
or cause to be paid to the Trustee all sums held in trust for any such series by
the Issuer or any paying agent hereunder, as required by this Section, such sums
to be held by the Trustee upon the trusts herein contained.

     Anything in this section to the contrary notwithstanding, the agreement to
hold sums in trust as provided in this section is subject to the provisions of
Section 9.05.

     Section 3.04. Certificate of the Issuer. Within 120 days after the close of
the fiscal year ended December 31, 2002, and within 120 days after the close of
each fiscal year thereafter, the Issuer will furnish to the Trustee a brief
certificate (which need not comply with Section 10.05) from the principal
executive, financial or accounting officer of the Issuer as to his or her
knowledge of the Issuer's compliance with all conditions and covenants under the
Indenture (such compliance to be determined without regard to any period of
grace or requirement of notice provided under the Indenture).

     At the time such certificate is filed, the Issuer will also file with the
Trustee a letter or statement of the independent accountants who shall have
certified the financial statements of the Issuer for its preceding fiscal year
to the effect that, in making the examination necessary for certification of
such financial statements, they have obtained no knowledge of any default by the
Issuer in the performance or fulfillment of any covenant, agreement or condition
contained in this Indenture, which default remains uncured at the date of such
letter or statement, or, if they shall have obtained knowledge of any such
uncured default, specifying in such letter or statement such default or defaults
and the nature and status thereof, it being understood that such accountants
shall not be liable directly or indirectly for failure to obtain knowledge of
any such default or defaults, and that nothing contained in this Section 3.04
shall be construed to require such accountants to make any investigation beyond
the scope required in connection with such examination.

     Section 3.05. Securityholders Lists. If and so long as the Trustee shall
not be the Security registrar for the Securities of any series, the Issuer will
furnish or cause to be furnished to the Trustee a list in such form as the
Trustee may reasonably require of the names and addresses of the holders of the
Securities of such series pursuant to Section 312 of the Trust Indenture Act of
1939 (a) semi-annually not more than 10 days after each record date for the
payment of interest on such Securities, as hereinabove specified, as of such
record date and on dates to be determined pursuant to Section 2.03 for
non-interest bearing Securities in each year, and (b) at such other times as the
Trustee may request in writing, within thirty days after receipt by the Issuer
of any such request as of a date not more than 10 days prior to the time such
information is furnished.

                                       25
<PAGE>

     Section 3.06. Reports by the Issuer. The Issuer covenants to:

     (a) file, whether or not required to do so by applicable law, with the
Trustee, within 15 days after the Issuer is required to file the same with the
Commission, copies of the annual reports and of the information, documents, and
other reports which the Issuer may be required to file with the Commission
pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934;
or, if the Issuer is not required to file with the Commission, annual reports,
information, documents and other reports pursuant to either Section 13 or
Section 15(d) of the Securities Exchange Act of 1934, then the Issuer will file
with the Trustee and will file with the Commission, in accordance with rules and
regulations prescribed by the Commission, such of the supplementary and periodic
information, documents and reports required pursuant to Section 13 of the
Securities Exchange Act of 1934 in respect of a security listed and registered
on a national securities exchange as may be prescribed in such rules and
regulations;

     (b) file with the Trustee and the Commission, in accordance with the rules
and regulations prescribed from time to time by the Securities and Exchange
Commission, such additional information, documents and reports with respect to
compliance by the Issuer with the conditions and covenants provided for in this
Indenture as may be required by such rules and regulations;

     (c) transmit to the Securityholders, in the manner and to the extent
provided in Section 10.04, such summaries of any information, documents and
reports required to be filed with the Trustee pursuant to the provisions of
subdivisions (a) and (b) of this Section 3.06 as may be required by the rules
and regulations of the Commission.

     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 Issuer's
compliance with any of its covenants hereunder (as to which the Trustee is
entitled to rely exclusively on Officers' Certificates).

     Section 3.07. Corporate Existence. So long as any of the Securities remain
unpaid, the Issuer will at all times (except as otherwise provided or permitted
elsewhere in this Indenture) do or cause to be done all things necessary to
preserve and keep in full force and effect its corporate existence.

     Section 3.08. Restrictions on Mergers, Sales and Consolidations. So long as
any of the Securities remain unpaid, the Issuer will not consolidate or merge
with or sell, convey or lease all or substantially all of its property to any
other corporation except as permitted in Article 8 hereof.

                                       26
<PAGE>

     Section 3.09. Further Assurances. From time to time whenever requested by
the Trustee, the Issuer will execute and deliver such further instruments and
assurances and do such further acts as may be reasonably necessary or proper to
carry out more effectually the purposes of this Indenture or to secure the
rights and remedies hereunder of the holders of the Securities of any series.

     Section 3.10. Limitation on Liens. Neither the Issuer nor any Cable
Guarantor shall create, incur or assume any Lien (other than any Permitted Lien)
on such Person's assets, including the Capital Stock of its Wholly Owned
Subsidiaries, to secure the payment of Indebtedness of the Issuer or any Cable
Guarantor that are pari passu with or subordinated in right of payment to the
Securities or the Cable Guarantees, unless the Issuer secures the Outstanding
Securities equally and ratably with (or prior to) all Indebtedness secured by
such Lien, so long as such Indebtedness shall be so secured.

     Section 3.11. Limitation on Sale and Leaseback Transactions. Neither the
Issuer nor any Cable Guarantor shall enter into any Sale and Leaseback
Transaction involving any of such Person's assets, including the Capital Stock
of its Wholly Owned Subsidiaries.

                                   Article 4
         REMEDIES OF THE TRUSTEE AND SECURITYHOLDERS ON EVENT OF DEFAULT

     SECTION 4.01. Event of Default Defined; Acceleration of Maturity; Waiver of
Default. "Event of Default" with respect to Securities of any series wherever
used herein, means each one of the following events which shall have occurred
and be continuing (whatever the reason for such Event of Default and whether it
shall be voluntary or involuntary or be effected by operation of law or pursuant
to any judgment, decree or order of any court or any order, rule or regulation
of any administrative or governmental body):

          (a) default by any Obligor in the payment of any installment of
     interest upon any of the Securities of such series as and when the same
     shall become due and payable, and continuance of such default for a period
     of 30 days; or

          (b) default by an Obligor in the payment of all or any part of the
     principal on any of the Securities of such series as and when the same
     shall become due and payable either at maturity, upon redemption, by
     declaration or otherwise; or

          (c) default by an Obligor in the performance, or breach by any
     Obligor, of any of its covenants or agreements in respect of the Securities
     of such series (other than a covenant or agreement in respect of the

                                       27
<PAGE>

     Securities of such series a default in whose performance or whose breach is
     elsewhere in this section specifically dealt with), and continuance of such
     default or breach for a period of 30 consecutive days after there has been
     given, by registered or certified mail, to the Issuer by the Trustee or to
     the Issuer and the Trustee by the Holders of at least 25% in principal
     amount of the Outstanding Securities of all series affected thereby, a
     written notice specifying such default or breach and requiring it to be
     remedied and stating that such notice is a "Notice of Default" hereunder;
     or

          (d) a court having jurisdiction in the premises shall enter a decree
     or order for relief in respect of any Obligor in an involuntary case under
     any applicable bankruptcy, insolvency or other similar law now or hereafter
     in effect, or appointing a receiver, liquidator, assignee, custodian,
     trustee or sequestrator (or similar official) of any Obligor or for any
     substantial part of such party's property and assets or ordering the
     winding up or liquidation of any Obligor's affairs, and such decree or
     order shall remain unstayed and in effect for a period of 180 consecutive
     days; or

          (e) any Obligor shall commence a voluntary case under any applicable
     bankruptcy, insolvency or other similar law now or hereafter in effect, or
     consent to the entry of an order for relief in an involuntary case under
     any such law, or consent to the appointment of or taking possession by a
     receiver, liquidator, assignee, custodian, trustee or sequestrator (or
     similar official) of such party or for any substantial part of such party's
     property, or make any general assignment for the benefit of creditors; or

          (f) any Cable Guarantee shall not be (or claimed by any Cable
     Guarantor not to be) in full force and effect; or

          (g) any other Event of Default provided in the supplemental indenture
     or resolution of the Board of Directors under which such series of
     Securities is issued or in the form of Security for such series.

     If an Event of Default described in clauses 4.01(a), 4.01(b), 4.01(c),
4.01(f), or 4.01(g) occurs and is continuing, then, and in each and every such
case, unless the principal of all of the Securities of such series shall have
already become due and payable, either the Trustee or the holders of not less
than 25% in aggregate principal amount of the Securities of any affected series
then Outstanding hereunder (each such series voting as a separate class) by
notice in writing to the Issuer (and to the Trustee if given by
Securityholders), may declare the entire principal (or, if the Securities of
such series are Original Issue Discount Securities, such portion of the
principal amount as may be specified in the terms of such series) of all
Securities of such series and the interest accrued thereon, if any, to be due
and payable immediately, and upon any such declaration the same

                                       28
<PAGE>

shall become immediately due and payable. If an Event of Default described in
clauses 4.01(d) or 4.01(e) occurs and is continuing, then the principal amount
of all the Securities then outstanding and interest accrued thereon, if any,
shall be and become immediately due and payable, without any notice or other
action by any Holder or the Trustee, to the full extent permitted by applicable
law.

     The foregoing provisions, however, are subject to the condition that if, at
any time after the principal (or, if the Securities are Original Issue Discount
Securities, such portion of the principal as may be specified in the terms
thereof) of the Securities of any series (or of all the Securities, as the case
may be) shall have been so declared due and payable, and before any judgment or
decree for the payment of the moneys due shall have been obtained or entered as
hereinafter provided, the Issuer shall pay or shall deposit with the Trustee a
sum sufficient to pay all matured installments of interest upon all the
Securities of such series (or of all the Securities, as the case may be) and the
principal of any and all Securities of such series (or of all the Securities, as
the case may be) which shall have become due otherwise than by acceleration
(with interest upon such principal and, to the extent that payment of such
interest is enforceable under applicable law, on overdue installments of
interest, at the same rate as the rate of interest or Yield to Maturity (in the
case of Original Issue Discount Securities) specified in the Securities of such
series (or at the respective rates of interest or Yields to Maturity of all the
Securities, as the case may be) to the date of such payment or deposit) and such
amount as shall be sufficient to cover reasonable compensation to the Trustee,
its agents, attorneys and counsel, and all other expenses and liabilities
incurred, and all advances made, by the Trustee except as a result of negligence
or bad faith, and if any and all Events of Default under the Indenture, other
than the non-payment of the principal of Securities which shall have become due
by acceleration, shall have been cured, waived or otherwise remedied as provided
herein--then and in every such case the holders of a majority in aggregate
principal amount of all the then outstanding Securities of all such series that
have been accelerated, each such series voting as a separate class, by written
notice to the Issuer and to the Trustee, may waive all defaults with respect to
such series (or with respect to all the Securities, as the case may be) and
rescind and annul such declaration and its consequences, but no such waiver or
rescission and annulment shall extend to or shall affect any subsequent default
or shall impair any right consequent thereon.

     For all purposes under this Indenture, if a portion of the principal of any
Original Issue Discount Securities shall have been accelerated and declared due
and payable pursuant to the provisions hereof, then, from and after such
declaration, unless such declaration has been rescinded and annulled, the
principal amount of such Original Issue Discount Securities shall be deemed, for
all purposes hereunder, to be such portion of the principal thereof as shall be
due and payable as a result of such acceleration, and payment of such portion of
the principal thereof as shall be due and payable as a result of such
acceleration,

                                       29
<PAGE>

together with interest, if any, thereon and all other amounts owing thereunder,
shall constitute payment in full of such Original Issue Discount Securities.

     Section 4.02. Collection of Indebtedness by Trustee; Trustee May Prove
Debt. The Issuer covenants that (a) in case default shall be made in the payment
of any installment of interest on any of the Securities of any series when such
interest shall have become due and payable, and such default shall have
continued for a period of 30 days or (b) in case default shall be made in the
payment of all or any part of the principal of any of the Securities of any
series when the same shall have become due and payable, whether upon maturity of
the Securities of such series or upon any redemption or by declaration or
otherwise--then upon demand of the Trustee, the Issuer will pay to the Trustee
for the benefit of the Holders of the Securities of such series the whole amount
that then shall have become due and payable on all Securities of such series for
principal or interest, as the case may be (with interest to the date of such
payment upon the overdue principal and, to the extent that payment of such
interest is enforceable under applicable law, on overdue installments of
interest at the same rate as the rate of interest or Yield to Maturity (in the
case of Original Issue Discount Securities) specified in the Securities of such
series); and in addition thereto, such further amount as shall be sufficient to
cover the costs and expenses of collection, including reasonable compensation to
the Trustee and each predecessor Trustee, their respective agents and counsel,
and any expenses and liabilities incurred, and all advances made, by the Trustee
and each predecessor Trustee except as a result of its negligence or bad faith.

     Until such demand is made by the Trustee, the Issuer may pay the principal
of and interest on the Securities of any series to the registered holders,
whether or not the principal of and interest on the Securities of such series be
overdue.

     In case the Issuer shall fail forthwith to pay such amounts upon such
demand, the Trustee, in its own name and as trustee of an express trust, shall
be entitled and empowered to institute any action or proceedings at law or in
equity for the collection of the sums so due and unpaid, and may prosecute any
such action or proceedings to judgment or final decree, and may enforce any such
judgment or final decree against the Issuer or other obligor upon such
Securities and collect in the manner provided by law out of the property of the
Issuer or other obligor upon such Securities, wherever situated, the moneys
adjudged or decreed to be payable.

     In case there shall be pending proceedings relative to the Issuer or any
other obligor upon the Securities under Title 11 of the United States Code or
any other applicable Federal or state bankruptcy, insolvency or other similar
law, or in case a receiver, assignee or trustee in bankruptcy or reorganization,
liquidator, sequestrator or similar official shall have been appointed for or
taken possession

of the Issuer or its property or such other obligor, or in case of any other
comparable judicial proceedings relative to the Issuer or other obligor upon the
Securities of any series, or to the creditors or property of the Issuer or such
other obligor, the Trustee, irrespective of whether the principal of any
Securities shall then be due and payable as therein expressed or by declaration
or otherwise and irrespective of whether the Trustee shall have made any demand
pursuant to the provisions of this Section, shall be entitled and empowered, by
intervention in such proceedings or otherwise:

          (a) to file and prove a claim or claims for the whole amount of
     principal and interest (or, if the Securities of any series are Original
     Issue Discount Securities, such portion of the principal amount as may be
     specified in the terms of such series) owing and unpaid in respect of the
     Securities of any series, and to file such other papers or documents as may
     be necessary or advisable in order to have the claims of the Trustee
     (including any claim for reasonable compensation to the Trustee and each
     predecessor Trustee, and their respective agents, attorneys and counsel,
     and for reimbursement of all expenses and liabilities incurred, and all
     advances made, by the Trustee and each predecessor Trustee, except as a
     result of negligence or bad faith) and of the Securityholders allowed in
     any judicial proceedings relative to the Issuer or other obligor upon the
     Securities of any series, or to the creditors or property of the Issuer or
     such other obligor,

          (b) unless prohibited by applicable law and regulations, to vote on
     behalf of the holders of the Securities of any series in any election of a
     trustee or a standby trustee in arrangement, reorganization, liquidation or
     other bankruptcy or insolvency proceedings or person performing similar
     functions in comparable proceedings, and

          (c) to collect and receive any moneys or other property payable or
     deliverable on any such claims, and to distribute all amounts received with
     respect to the claims of the Securityholders and of the Trustee on their
     behalf; and any trustee, receiver, or liquidator, custodian or other
     similar official is hereby authorized by each of the Securityholders to
     make payments to the Trustee, and, in the event that the Trustee shall
     consent to the making of payments directly to the Securityholders, to pay
     to the Trustee such amounts as shall be sufficient to cover reasonable
     compensation to the Trustee, each predecessor Trustee and their respective
     agents, attorneys and counsel, and all other expenses and liabilities
     incurred, and all advances made, by the Trustee and each predecessor
     Trustee except as a result of negligence or bad faith and all other amounts
     due to the Trustee or any predecessor Trustee pursuant to Section 5.06.

                                       31
<PAGE>

     Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or vote for or accept or adopt on behalf of any
Securityholder any plan or reorganization, arrangement, adjustment or
composition affecting the Securities of any series or the rights of any Holder
thereof, or to authorize the Trustee to vote in respect of the claim of any
Securityholder in any such proceeding except, as aforesaid, to vote for the
election of a trustee in bankruptcy or similar person.

     All rights of action and of asserting claims under this Indenture, or under
any of the Securities, may be enforced by the Trustee without the possession of
any of the Securities or the production thereof on any trial or other
proceedings relative thereto, and any such action or proceedings instituted by
the Trustee shall be brought in its own name as trustee of an express trust, and
any recovery of judgment, subject to the payment of the expenses, disbursements
and compensation of the Trustee, each predecessor Trustee and their respective
agents and attorneys, shall be for the ratable benefit of the holders of the
Securities in respect of which such action was taken.

     In any proceedings brought by the Trustee (and also any proceedings
involving the interpretation of any provision of this Indenture to which the
Trustee shall be a party) the Trustee shall be held to represent all the holders
of the Securities in respect to which such action was taken, and it shall not be
necessary to make any holders of such Securities parties to any such
proceedings.

     Section 4.03. Application of Proceeds. Any moneys collected by the Trustee
pursuant to this Article in respect of any series shall be applied in the
following order at the date or dates fixed by the Trustee and, in case of the
distribution of such moneys on account of principal or interest, upon
presentation of the several Securities in respect of which monies have been
collected and stamping (or otherwise noting) thereon the payment, or issuing
Securities of such series in reduced principal amounts in exchange for the
presented Securities of like series if only partially paid, or upon surrender
thereof if fully paid:

          FIRST: To the payment of costs and expenses applicable to such series
     in respect of which monies have been collected, including reasonable
     compensation to the Trustee and each predecessor Trustee and their
     respective agents and attorneys and of all expenses and liabilities
     incurred, and all advances made, by the Trustee and each predecessor
     Trustee except as a result of negligence or bad faith, and all other
     amounts due to the Trustee or any predecessor Trustee pursuant to Section
     5.06;

          SECOND: In case the principal of the Securities of such series in
     respect of which moneys have been collected shall not have become and be
     then due and payable, to the payment of interest on the Securities of such
     series in default in the order of the maturity of the installments of

                                       32
<PAGE>

     such interest, with interest (to the extent that such interest has been
     collected by the Trustee) upon the overdue installments of interest at the
     same rate as the rate of interest or Yield to Maturity (in the case of
     Original Issue Discount Securities) specified in such Securities, such
     payments to be made ratably to the persons entitled thereto, without
     discrimination or preference;

          THIRD: In case the principal of the Securities of such series in
     respect of which moneys have been collected shall have become and shall be
     then due and payable, to the payment of the whole amount then owing and
     unpaid upon all the Securities of such series for principal and interest,
     with interest upon the overdue principal, and (to the extent that such
     interest has been collected by the Trustee) upon overdue installments of
     interest at the same rate as the rate of interest or Yield to Maturity (in
     the case of Original Issue Discount Securities) specified in the Securities
     of such series; and in case such moneys shall be insufficient to pay in
     full the whole amount so due and unpaid upon the Securities of such series,
     then to the payment of such principal and interest or yield to maturity,
     without preference or priority of principal over interest or yield to
     maturity, or of interest or yield to maturity over principal, or of any
     installment of interest over any other installment of interest, or of any
     Security of such series over any other Security of such series, ratably to
     the aggregate of such principal and accrued and unpaid interest or yield to
     maturity; and

          FOURTH: To the payment of the remainder, if any, to the Issuer or any
     other person lawfully entitled thereto.

     Section 4.04. Suits for Enforcement. In case an Event of Default has
occurred, has not been waived and is continuing, the Trustee may proceed to
protect and enforce the rights vested in it by this Indenture, either at law or
in equity or in bankruptcy or otherwise, whether for the specific enforcement of
any covenant or agreement contained in this Indenture or in aid of the exercise
of any power granted in this Indenture or to enforce any other legal or
equitable right vested in the Trustee by this Indenture or by law.

     Section 4.05. Restoration of Rights on Abandonment of Proceedings. In case
the Trustee shall have proceeded to enforce any right under this Indenture and
such proceedings shall have been discontinued or abandoned for any reason, or
shall have been determined adversely to the Trustee, then and in every such case
the Issuer, any Cable Guarantors and the Trustee shall be restored respectively
to their former positions and rights hereunder, and all rights, remedies and
powers of the Issuer, any Cable Guarantors, the Trustee and the Securityholders
shall continue as though no such proceedings had been taken.

     Section 4.06. Limitations on Suits by Securityholder. No holder of any
Security of any series shall have any right by virtue or by availing of any
provision of this Indenture to institute any action or proceeding at law or in
equity or in bankruptcy or otherwise upon or under or with respect to this
Indenture, or for the appointment of a trustee, receiver, liquidator, custodian
or other similar official or for any other remedy hereunder, unless such holder
previously shall have given to the Trustee written notice of an Event of Default
and of the continuance thereof, as hereinbefore provided, and unless also the
holders of not less than 25% in aggregate principal amount of the Securities of
such series then outstanding shall have made written request upon the Trustee to
institute such action or proceedings in respect of such Event of Default in its
own name as trustee hereunder and shall have offered to the Trustee indemnity
satisfactory to the Trustee against the costs, expenses and liabilities to be
incurred therein or thereby and the Trustee for 60 days after its receipt of
such notice, request and offer of indemnity shall have failed to institute any
such action or proceeding and no direction inconsistent with such written
request shall have been given to the Trustee pursuant to Section 4.09; it being
understood and intended, and being expressly covenanted by the Holder of every
Security with every other Holder and the Trustee, that no one or more Holders of
Securities of any series shall have any right in any manner whatever by virtue
or by availing of any provision of this Indenture to affect, disturb or
prejudice the rights of any other such Holder of Securities, or to obtain or
seek to obtain priority over or preference to any other such Holder or to
enforce any right under this Indenture, except in the manner herein provided and
for the equal, ratable and common benefit of all Holders of Securities of the
applicable series. For the protection and enforcement of the provisions of this
Section, each and every Securityholder and the Trustee shall be entitled to such
relief as can be given either at law or in equity.

     Section 4.07. Unconditional Right of Securityholders to Institute Certain
Suits. Notwithstanding any other provision in this Indenture and any provision
of any Security, the right of any Holder of any Security to receive payment of
the principal of, premium, if any, or interest on such Security on or after the
respective due dates expressed in such Security, or to institute suit for the
enforcement of any such payment on or after such respective dates, shall not be
impaired or affected without the consent of such Holder.

     Section 4.08. Powers and Remedies Cumulative; Delay or Omission Not Waiver
of Default. Except as provided in Section 4.06, no right or remedy herein
conferred upon or reserved to the Trustee or to the Securityholders is intended
to be exclusive of any other right or remedy, and every right and remedy shall,
to the extent permitted by law, be cumulative and in addition to every other
right and remedy given hereunder or now or hereafter existing at law or in
equity or otherwise. The assertion or employment of any right or remedy
hereunder, or otherwise, shall not prevent the concurrent assertion or
employment of any other appropriate right or remedy.

                                       34
<PAGE>

     No delay or omission of the Trustee or of any Securityholder to exercise
any right or power accruing upon any Event of Default occurring and continuing
as aforesaid shall impair any such right or power or shall be construed to be a
waiver of any such Event of Default or an acquiescence therein; and, subject to
Section 4.06, every power and remedy given by this Indenture or by law to the
Trustee or to the Securityholders may be exercised from time to time, and as
often as shall be deemed expedient, by the Trustee or by the Securityholders.

     Section 4.09. Control by Securityholders. The Holders of a majority in
aggregate principal amount of the Securities of each series affected (with each
series voting as a separate class) at the time outstanding shall have the right
to direct the time, method, and place of conducting any proceeding for any
remedy available to the Trustee, or exercising any trust or power conferred on
the Trustee with respect to the Securities of such series by this Indenture;
provided that such direction shall not be otherwise than in accordance with law
and the provisions of this Indenture and provided further that (subject to the
provisions of Section 5.01) the Trustee shall have the right to decline to
follow any such direction if the Trustee, being advised by counsel, shall
determine that the action or proceeding so directed may not lawfully be taken or
if the Trustee in good faith by its board of directors, the executive committee,
or a trust committee of directors or Responsible Officers of the Trustee shall
determine that the action or proceedings so directed would involve the Trustee
in personal liability or if the Trustee in good faith shall so determine that
the actions or forbearances specified in or pursuant to such direction would be
unduly prejudicial to the interests of Holders of the Securities of all series
so affected not joining in the giving of said direction.

     Nothing in this Indenture shall impair the right of the Trustee to take any
action which is not inconsistent with such direction or directions by
Securityholders.

     Section 4.10. Waiver of Past Defaults. Prior to a declaration of the
acceleration of the maturity of the Securities of any series as provided in
Section 4.01, the Holders of a majority in aggregate principal amount of the
Securities of such series at the time Outstanding (each such series voting as a
separate class) may on behalf of the Holders of all the Securities of such
series waive an existing default or Event of Default, except a default in the
payment of Principal of or interest on any Security as specified in clauses (a)
or (b) of Section 4.01 or in respect of a covenant or provision hereof which
cannot be modified or amended without the consent of each Holder affected as
provided in. In the case of any such waiver, the Issuer, the Trustee and the
Holders of the Securities of each series affected shall be restored to their
former positions and rights hereunder, respectively.

         Upon any such waiver, such default shall cease to exist and be deemed
to have been cured and not to have occurred, and any Event of Default arising

                                       35
<PAGE>

therefrom shall be deemed to have been cured, and not to have occurred for every
purpose of this Indenture; but no such waiver shall extend to any subsequent or
other default or Event of Default or impair any right consequent thereon.
Section 4.11. Trustee to Give Notice of Default, But May Withhold in Certain
Circumstances. The Trustee shall give to the Securityholders of any series, as
the names and addresses of such Holders appear on the registry books, notice by
mail of all defaults known to Responsible Officers of the Trustee which have
occurred with respect to such series, such notice to be transmitted within 90
days after the occurrence thereof, unless such defaults shall have been cured
before the giving of such notice (the term "default" or "defaults" for the
purposes of this section being hereby defined to mean any event or condition
which is, or with notice or lapse of time or both would become, an Event of
Default); provided that, except in the case of default in the payment of the
principal of or interest on any of the Securities of such series, or in the
payment of any sinking or purchase fund installment with respect to the
Securities of such series, the Trustee shall be protected in withholding such
notice if and so long as the board of directors, the executive committee, or a
trust committee of directors or trustees and/or Responsible Officers of the
Trustee in good faith determines that the withholding of such notice is in the
interests of the Securityholders of such series.

     Section 4.12. Right of Court to Require Filing of Undertaking to Pay Costs.
All parties to this Indenture agree, and each Holder of any Security by his
acceptance thereof shall be deemed to have agreed, that any court may in its
discretion require, in any suit for the enforcement of any right or remedy under
this Indenture or in any suit against the Trustee for any action taken, suffered
or omitted by it as Trustee, the filing by any party litigant in such suit of an
undertaking to pay the costs of such suit, and that such court may in its
discretion assess reasonable costs, including reasonable attorneys' fees and
expenses, against any party litigant in such suit, having due regard to the
merits and good faith of the claims or defenses made by such party litigant; but
the provisions of this section shall not apply to any suit instituted by the
Trustee, to any suit instituted by any Securityholder or group of
Securityholders of any series holding in the aggregate more than 10% in
aggregate principal amount of the Securities of such series, or, to any suit
instituted by a Holder pursuant to Section 4.07.

                                   Article 5
                             CONCERNING THE TRUSTEE

     Section 5.01. Duties and Responsibilities of the Trustee; During Default;
Prior to Default. With respect to the Holders of any series of Securities issued
hereunder, the Trustee, prior to the occurrence of an Event of Default with
respect to the Securities of a particular series and after the curing or waiving
of all Events of Default which may have occurred with respect to such series,
undertakes to

                                       36
<PAGE>

perform such duties and only such duties as are specifically set forth in this
Indenture. In case an Event of Default with respect to the Securities of a
series has occurred (which has not been cured or waived) 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 their exercise, as a prudent person would
exercise or use under the circumstances in the conduct of such person's own
affairs.

          (a) Prior to the occurrence of an Event of Default with respect to the
     Securities of any series and after the curing or waiving of all such Events
     of Default with respect to such series which may have occurred:

               (i) the duties and obligations of the Trustee with respect to the
          Securities of any Series shall be determined solely by the express
          provisions of this Indenture, and the Trustee shall not be liable
          except for the performance of such duties and obligations as are
          specifically set forth in this Indenture, and no implied covenants or
          obligations shall be read into this Indenture against the Trustee; and

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

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

               (i) this subsection (b) shall not be construed to limit the
          effect of subsection (a) of this Section;

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

               (iii) the Trustee shall not be liable with respect to any action
          taken, suffered or omitted to be taken by it in good faith in
          accordance with the direction of the holders relating to the time,

                                       37
<PAGE>

          method and place of conducting any proceeding for any remedy available
          to the Trustee, or exercising any trust or power conferred upon the
          Trustee, under this Indenture.

     None of the provisions contained in this Indenture shall require the
Trustee to expend or risk its own funds or otherwise incur personal financial
liability in the performance of any of its duties or in the exercise of any of
its rights or powers, if there shall be reasonable ground for believing that the
repayment of such funds or adequate indemnity against such liability is not
reasonably assured to it.

     The provisions of this Section 5.01 are in furtherance of and subject to
Sections 315 and 316 of the Trust Indenture Act of 1939.

     Whether or not therein expressly provided, every provision of this
Indenture relating to the conduct or affecting the liability of or affording
protection to the Trustee shall be subject to the provisions of this Section
5.01.

     Section 5.02. Certain Rights of the Trustee. In furtherance of and subject
to the Trust Indenture Act of 1939, and subject to Section 5.01:

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

          (b) any request, direction, order or demand of the Issuer mentioned
     herein shall be sufficiently evidenced by an Officers' Certificate (unless
     other evidence in respect thereof be herein specifically prescribed); and
     any resolution of the Board of Directors may be evidenced to the Trustee by
     a copy thereof certified by the secretary or an assistant secretary of the
     Issuer;

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

          (d) the Trustee shall be under no obligation to exercise any of the
     trusts or powers vested in it by this Indenture at the request, order or
     direction of any of the Securityholders pursuant to the provisions of this
     Indenture, unless such Securityholders shall have offered to the Trustee

                                       38
<PAGE>

     reasonable security or indemnity against the costs, expenses and
     liabilities which might be incurred by it in connection with such request,
     order or direction;

          (e) the Trustee shall not be liable for any action taken or omitted by
     it in good faith and believed by it to be authorized or within the
     discretion, rights or powers conferred upon it by this Indenture;

          (f) prior to the occurrence of an Event of Default hereunder and after
     the curing or waiving of all Events of Default, the Trustee shall not be
     bound to make any investigation into the facts or matters stated in any
     resolution, certificate, statement, instrument, opinion, report, notice,
     request, consent, order, approval, appraisal, bond, debenture, note,
     coupon, security, or other paper or document unless requested in writing so
     to do by the holders of not less than a majority in aggregate principal
     amount of the Securities of all series affected then outstanding; provided
     that, if the payment within a reasonable time to the Trustee of the costs,
     expenses or liabilities likely to be incurred by it in the making of such
     investigation is, in the opinion of the Trustee, not reasonably assured to
     the Trustee by the security afforded to it by the terms of this Indenture,
     the Trustee may require indemnity satisfactory to it against such expenses
     or liabilities as a condition to proceeding; the reasonable expenses of
     every such investigation shall be paid by the Issuer or, if paid by the
     Trustee or any predecessor trustee, shall be repaid by the Issuer upon
     demand;

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

          (h) the Trustee shall not be liable for any action taken, suffered or
     omitted in good faith and believed by it to be authorized or within the
     discretion, rights or powers conferred upon it by this Indenture;

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

          (j) the rights, privileges, protections, immunities and benefits given
     to the Trustee, including, without limitation, its right to be indemnified,
     are extended to, and shall be enforceable by, the Trustee in

                                       39
<PAGE>

     each of its capacities hereunder, and each agent, custodian and other
     Person employed to act hereunder; and

          (k) the Trustee may request that the Issuer deliver an Officers'
     Certificate setting forth the names of individuals and/or titles of
     officers authorized at such time to take specified actions pursuant to this
     Indenture, which Officers' Certificate may be signed by any person
     authorized to sign an Officers' Certificate, including any person specified
     as so authorized in any such certificate previously delivered and not
     superseded.

     Section 5.03. Trustee Not Responsible for Recitals, Disposition of
Securities or Application of Proceeds Thereof. The recitals contained herein and
in the Securities, except the Trustee's certificates of authentication, shall be
taken as the statements of the Issuer, and the Trustee assumes no responsibility
for the correctness of the same. The Trustee makes no representation as to the
validity or sufficiency of this Indenture, the Securities or the Cable
Guarantees. The Trustee shall not be accountable for the use or application by
the Issuer of any of the Securities or of the proceeds thereof.

     Section 5.04. Trustee and Agents May Hold Securities; Collections, etc. The
Trustee or any agent of the Issuer or the Trustee, in its individual or any
other capacity, may become the owner or pledgee of Securities with the same
rights it would have if it were not the Trustee or such agent and may otherwise
deal with the Issuer and receive, collect, hold and retain collections from the
Issuer with the same rights it would have if it were not the Trustee or such
agent.

     Section 5.05. Moneys Held by Trustee. All moneys received by the Trustee in
trust hereunder need not be segregated from other funds except to the extent
required by mandatory provisions of law. Neither the Trustee nor any agent of
the Issuer or the Trustee shall be under any liability for interest on any
moneys received by it hereunder.

     Section 5.06. Compensation and Indemnification of Trustee and Its Prior
Claim. The Issuer covenants and agrees to pay to the Trustee from time to time,
and the Trustee shall be entitled to, such compensation as shall be agreed in
writing from time to time by the Issuer and the Trustee (which shall not be
limited by any provision of law in regard to the compensation of a trustee of an
express trust) and the Issuer covenants and agrees to pay or reimburse the
Trustee and each predecessor Trustee upon its request for all reasonable
expenses, disbursements and advances incurred or made by or on behalf of it in
accordance with any of the provisions of this Indenture (including the
reasonable compensation and the expenses and disbursements of its counsel and of
all agents and other persons not regularly in its employ) except to the extent
any such expense, disbursement or advance may arise from its negligence or bad
faith. The Issuer also covenants and agrees to indemnify the Trustee and each
predecessor

                                       40

Trustee for, and to hold it harmless against, any loss, liability or expense
arising out of or in connection with the acceptance or administration of this
Indenture or the trusts hereunder and the performance of its duties hereunder,
including the costs and expenses of defending itself against or investigating
any claim of liability (whether asserted by the Issuer, a Cable Guarantor, a
Holder or any other Person) in the premises, except to the extent such loss,
liability or expense is due to the negligence or bad faith of the Trustee or
such predecessor Trustee. The obligations of the Issuer under this section to
compensate and indemnify the Trustee and each predecessor Trustee and to pay or
reimburse the Trustee and each predecessor Trustee for expenses, disbursements
and advances shall constitute additional indebtedness hereunder and shall
survive the satisfaction and discharge of this Indenture or the resignation or
removal of the Trustee. Such additional indebtedness shall be a senior claim and
lien to that of the Securities upon all property and funds held or collected by
the Trustee as such, except funds held in trust for the benefit of the holders
of particular Securities, and the Securities are hereby subordinated to such
senior claim. The parties agree that if the Trustee renders services following
an Event of Default under Section 4.01(d) or (e), compensation for such services
is intended to constitute administrative expense under any bankruptcy law.

     Section 5.07. Right of Trustee to Rely on Officers' Certificate, etc.
Subject to Sections 5.01 and 5.02, whenever in the administration of the trusts
of this Indenture the Trustee shall deem it necessary or desirable that a matter
be proved or established prior to taking or suffering or omitting any action
hereunder, such matter (unless other evidence in respect thereof be herein
specifically prescribed) may, in the absence of negligence or bad faith on the
part of the Trustee, be deemed to be conclusively proved and established by an
Officers' Certificate delivered to the Trustee, and such certificate, in the
absence of negligence or bad faith on the part of the Trustee, shall be full
warrant to the Trustee for any action taken, suffered or omitted by it under the
provisions of this Indenture upon the faith thereof.

     Section 5.08. Persons Eligible for Appointment as Trustee. The Trustee for
each series of Securities hereunder shall at all times be a corporation which is
eligible in accordance with the provisions of Section 310(a) of the Trust
Indenture Act of 1939 and which has, or is a Wholly-Owned Subsidiary, directly
or indirectly of a bank holding company which has, a combined capital and
surplus of $50,000,000. If such corporation or holding company publishes reports
of condition at least annually, pursuant to law or to the requirements of a
Federal, State or District of Columbia supervising or examining authority, then
for the purposes of this Section, the combined capital and surplus of such
corporation or holding company shall be deemed to be its combined capital and
surplus as set forth in its most recent report of condition so published.

     Section 5.09. Resignation and Removal; Appointment of Successor Trustee.
(a) The Trustee, or any trustee or trustees hereafter appointed, may at any time
resign with respect to one or more or all series of Securities by giving written
notice of resignation to the Issuer. Upon receiving such notice of resignation,
the Issuer shall promptly appoint a successor trustee or trustees with respect
to the applicable series by written instrument in duplicate, executed by
authority of the Board of Directors, one copy of which instrument shall be
delivered to the resigning Trustee and one copy to the successor trustee or
trustees. If no successor Trustee shall have been so appointed with respect to
any series and have accepted appointment within 30 days after the mailing of
such notice of resignation, the resigning Trustee may petition, at the expense
of the Issuer, any court of competent jurisdiction for the appointment of a
successor Trustee, or any Securityholder who has been a bona fide Holder of a
Security or Securities of the applicable series for at least six months may,
subject to the provisions of Section 4.12, on behalf of himself and all others
similarly situated, petition any such court for the appointment of a successor
Trustee. Such court may thereupon, after such notice, if any, as it may deem
proper and prescribe, appoint a successor Trustee.

     (b) In case at any time any of the following shall occur:

          (i) the Trustee shall fail to comply with the provisions of Section
     310(b) of the Trust Indenture Act of 1939 with respect to any series of
     Securities after written request therefor by the Issuer or by any
     Securityholder who has been a bona fide Holder of a Security or Securities
     of such series for at least six months; or

          (ii) the Trustee shall cease to be eligible in accordance with the
     provisions of Section 310(a) of the Trust Indenture Act of 1939 and shall
     fail to resign after written request therefor by the Issuer or by any
     Securityholder; or

          (iii) the Trustee shall become incapable of acting with respect to any
     series of Securities, or shall be adjudged a bankrupt or insolvent, or a
     receiver or liquidator of the Trustee or of its property shall be
     appointed, or any public officer shall take charge or control of the
     Trustee or of its property or affairs for the purpose of rehabilitation,
     conservation or liquidation;

then, in any case, the Issuer may remove the Trustee with respect to the
applicable series of Securities and appoint a successor trustee for such series
by written instrument, in duplicate, executed by order of the Board of Directors
of the Issuer, one copy of which instrument shall be delivered to the Trustee so
removed and one copy to the successor Trustee, or, subject to Section 315(e) of
the Trust Indenture Act of 1939, any Securityholder who has been a bona fide
Holder of a

                                       42
<PAGE>

Security or Securities of such series for at least six months may on behalf of
himself and all others similarly situated, petition any court of competent
jurisdiction for the removal of the Trustee and the appointment of a successor
trustee with respect to such series. Such court may thereupon, after such
notice, if any, as it may deem proper and prescribe, remove the Trustee and
appoint a successor trustee.

     (c) The Holders of a majority in aggregate principal amount of the
Securities of each series at the time outstanding may at any time remove the
Trustee with respect to Securities of such series and appoint a successor
Trustee with respect to the Securities of such series by delivering to the
Trustee so removed, to the successor Trustee so appointed and to the Issuer the
evidence provided in Section 6.01 of the action in that regard taken by the
Securityholders.

     (d) Any resignation or removal of the Trustee with respect to any series
and any appointment of a successor trustee with respect to such series pursuant
to any of the provisions of this Section 5.09 shall become effective upon
acceptance of appointment by the successor trustee as provided in Section 5.10.

     Section 5.10. Acceptance of Appointment by Successor. Any successor Trustee
appointed as provided in Section 5.09 shall execute and deliver to the Issuer
and to its predecessor Trustee an instrument accepting such appointment
hereunder, and thereupon the resignation or removal of the predecessor Trustee
with respect to all or any applicable series shall become effective and such
successor Trustee, without any further act, deed or conveyance, shall become
vested with all rights, powers, duties and obligations with respect to such
series of its predecessor hereunder, with like effect as if originally named as
Trustee for such series hereunder; but, nevertheless, on the written request of
the Issuer or of the successor Trustee, upon payment of its charges then unpaid,
the Trustee ceasing to act shall, subject to Section 5.06, pay over to the
successor Trustee all moneys at the time held by it hereunder and shall execute
and deliver an instrument transferring to such successor Trustee all such
rights, powers, duties and obligations. Upon request of any such successor
Trustee, the Issuer shall execute any and all instruments in writing for more
fully and certainly vesting in and confirming to such successor Trustee all such
rights and powers. Any Trustee ceasing to act shall, nevertheless, retain a
prior claim upon all property or funds held or collected by such Trustee to
secure any amounts then due it pursuant to the provisions of Section 5.06.

     If a successor Trustee is appointed with respect to the Securities of one
or more (but not all) series, the Issuer, the predecessor Trustee and each
successor Trustee with respect to the Securities of any applicable series shall
execute and deliver an indenture supplemental hereto which shall contain such
provisions as shall be deemed necessary or desirable to confirm that all the
rights, powers, trusts and duties of the predecessor Trustee with respect to the
Securities of any

                                       43
<PAGE>

series as to which the predecessor Trustee is not retiring shall continue to be
vested in the predecessor Trustee, and shall add to or change any of the
provisions of this Indenture as shall be necessary to provide for or facilitate
the administration of the trusts hereunder by more than one Trustee, it being
understood that nothing herein or in such supplemental indenture shall
constitute such Trustees co-trustees of the same trust and that each such
Trustee shall be Trustee of a trust or trusts under separate indentures.

     Upon acceptance of appointment by any successor Trustee as provided in this
Section 5.10, the Issuer shall mail notice thereof by first-class mail to the
Holders of Securities of any series for which such successor Trustee is acting
as Trustee at their last addresses as they shall appear in the Security
register. If the acceptance of appointment is substantially contemporaneous with
the resignation, then the notice called for by the preceding sentence may be
combined with the notice called for by Section 5.09. If the Issuer fails to mail
such notice within ten days after acceptance of appointment by the successor
Trustee, the successor Trustee shall cause such notice to be mailed at the
expense of the Issuer.

     Section 5.11. Merger, Conversion, Consolidation or Succession to Business
of Trustee. Any corporation into which the Trustee may be merged or converted or
with which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any
corporation succeeding to all or substantially all the corporate trust business
of the Trustee, shall be the successor of the Trustee hereunder, provided that
such corporation shall be eligible under the provisions of Section 5.08, without
the execution or filing of any paper or any further act on the part of any of
the parties hereto, anything herein to the contrary notwithstanding.

     In case at the time such successor to the Trustee shall succeed to the
trusts created by this Indenture any of the Securities of any series shall have
been authenticated but not delivered, any such successor to the Trustee may
adopt the certificate of authentication of any predecessor Trustee and deliver
such Securities so authenticated; and, in case at that time any of the
Securities of any series shall not have been authenticated, any successor to the
Trustee may authenticate such Securities either in the name of any predecessor
hereunder or in the name of the successor Trustee; and in all such cases such
certificate shall have the full force which it is anywhere in the Securities of
such series or in this Indenture provided that the certificate of the Trustee
shall have; provided, that the right to adopt the certificate of authentication
of any predecessor Trustee or to authenticate Securities of any series in the
name of any predecessor Trustee shall apply only to its successor or successors
by merger, conversion or consolidation.

     Section 5.12. Reports to the Trustee. The Trustee shall transmit to Holders
such reports concerning the Trustee and its actions under this Indenture as may
be required pursuant to the Trust Indenture Act at the times and in the

                                       44
<PAGE>

manner provided pursuant thereto. If required by Section 313(a) of the Trust
Indenture Act, the Trustee shall, within sixty days after each May 15 following
the date of the initial issuance of Securities under this Indenture deliver to
Holders a brief report, dated as of such May 15, which complies with the
provisions of such Section 313(a).

     A copy of each such report shall, at the time of such transmission to
Holders, be filed by the Trustee with each stock exchange, if any, upon which
the Securities are listed, with the Commission and with the Issuer. The Issuer
will promptly notify the Trustee when the Securities are listed on any stock
exchange and of any delisting thereof.

                                   Article 6
                         CONCERNING THE SECURITYHOLDERS

     Section 6.01. Evidence of Action Taken by Securityholders. Any request,
demand, authorization, direction, notice, consent, waiver or other action
provided by this Indenture to be given or taken by a specified percentage in
principal amount of the Securityholders of any or all series may be embodied in
and evidenced by one or more instruments of substantially similar tenor signed
by such specified percentage of Securityholders in person or by agent duly
appointed in writing; and, except as herein otherwise expressly provided, such
action shall become effective when such instrument or instruments are delivered
to the Trustee. Proof of execution of any instrument or of a writing appointing
any such agent shall be sufficient for any purpose of this Indenture and
(subject to Sections 5.01 and 5.02) conclusive in favor of the Trustee and the
Issuer, if made in the manner provided in this Article.

     Section 6.02. Proof of Execution of Instruments and of Holding of
Securities; Record Date. Subject to Sections 5.01 and 5.02, the execution of any
instrument by a Securityholder or his agent or proxy may be proved by the
certificate of any notary public or other officer authorized to take
acknowledgment of deeds, that the Person executing such instrument acknowledged
to such notary public or other such officer the execution thereof, or by an
affidavit of a witness to such execution sworn to before any such notary public
or other officer. Where such execution is by an officer of a corporation or
association or a member of a partnership on behalf of such corporation,
association or partnership, as the case may be, or by any other Person acting in
a representative capacity, such certificate or affidavit shall also constitute
sufficient proof of such Person's authority. The holding of Securities shall be
proved by the Security register or by a certificate of the registrar thereof.
The Issuer may set a record date for purposes of determining the identity of
holders of Securities of any series entitled to vote or consent to any action
referred to in Section 6.01, which record date may be set at any time or from
time to time by notice to the Trustee,

                                       45
<PAGE>

for any date or dates (in the case of any adjournment or reconsideration) not
more than 60 days nor less than five days prior to the proposed date of such
vote or consent, and thereafter, notwithstanding any other provisions hereof,
only holders of Securities of such series of record on such record date shall be
entitled to so vote or give such consent or revoke such vote or consent.

     Section 6.03. Holders to Be Treated as Owners. Prior to due presentment of
a Security for registration of transfer, the Issuer, the Trustee and any agent
of the Issuer or the Trustee may deem and treat the person in whose name any
Security shall be registered upon the Security register for such series as the
absolute owner of such Security (whether or not such Security shall be overdue
and notwithstanding any notation of ownership or other writing thereon) for the
purpose of receiving payment of or on account of the principal of and, subject
to the provisions of this Indenture, interest on such Security and for all other
purposes; and neither the Issuer nor the Trustee nor any agent of the Issuer or
the Trustee shall be affected by any notice to the contrary. All such payments
so made to any such person, or upon his order, shall be valid, and, to the
extent of the sum or sums so paid, effectual to satisfy and discharge the
liability for moneys payable upon any such Security.

     Section 6.04. Securities Owned by Issuer Deemed Not Outstanding. In
determining whether the Holders of the requisite aggregate principal amount of
Outstanding Securities of any or all series have concurred in any direction,
consent or waiver under this Indenture, Securities which are owned by the Issuer
or any other obligor on the Securities with respect to which such determination
is being made or by any person directly or indirectly controlling or controlled
by or under direct or indirect common control with the Issuer or any other
obligor on the Securities with respect to which such determination is being made
shall be disregarded and deemed not to be Outstanding for the purpose of any
such determination, except that for the purpose of determining whether the
Trustee shall be protected in relying on any such direction, consent or waiver
only Securities as to which the Trustee has received written notice are so owned
shall be so disregarded. Securities so owned which have been pledged in good
faith may be regarded as Outstanding if the pledgee establishes to the
satisfaction of the Trustee the pledgee's right so to act with respect to such
Securities and that the pledgee is not the Issuer or any other obligor upon the
Securities or any person directly or indirectly controlling or controlled by or
under direct or indirect common control with the Issuer or any other obligor on
the Securities. In case of a dispute as to such right, the advice of counsel
shall be full protection in respect of any decision made by the Trustee in
accordance with such advice. Upon request of the Trustee, the Issuer shall
furnish to the Trustee promptly an Officers' Certificate listing and identifying
all Securities, if any, known by the Issuer to be owned or held by or for the
account of any of the above-described persons; and, subject to Sections 5.01 and
5.02, the Trustee shall be entitled to accept such Officers' Certificate as
conclusive evidence of the facts therein set forth and of

                                       46
<PAGE>

the fact that all Securities not listed therein are Outstanding for the purpose
of any such determination.

     Section 6.05. Right of Revocation of Action Taken. At any time prior to
(but not after) the evidencing to the Trustee, as provided in Section 6.01, of
the taking of any action by the Holders of the percentage in aggregate principal
amount of the Securities of any or all series, as the case may be, specified in
this Indenture in connection with such action, any Holder of a Security the
serial number of which is shown by the evidence to be included among the serial
numbers of the Securities the Holders of which have consented to such action
may, by filing written notice at the Corporate Trust Office and upon proof of
holding as provided in this Article, revoke such action so far as concerns such
Security. Except as aforesaid any such action taken by the Holder of any
Security shall be conclusive and binding upon such Holder and upon all future
Holders and owners of such Security and of any Securities issued in exchange or
substitution therefor, irrespective of whether or not any notation in regard
thereto is made upon any such Security. Any action taken by the Holders of the
percentage in aggregate principal amount of the Securities of any or all series,
as the case may be, specified in this Indenture in connection with such action
shall be conclusively binding upon the Issuer, the Trustee and the Holders of
all the Securities affected by such action.

                                   Article 7
                             SUPPLEMENTAL INDENTURES

     Section 7.01. Supplemental Indentures Without Consent of Securityholders.
The Issuer, when authorized by a resolution of its Board of Directors certified
to the Trustee, and the Trustee may from time to time and at any time enter into
an indenture or indentures supplemental hereto for one or more of the following
purposes:

     (a) to evidence the succession of another corporation to the Issuer, or
successive successions, and the assumption by the successor corporation of the
covenants, agreements and obligations of the Issuer pursuant to Article 8;

     (b) to cure any ambiguity or to correct or supplement any provision
contained herein or in any supplemental indenture which may be defective or
inconsistent with any other provision contained herein or in any supplemental
indenture; or to make such other provisions in regard to matters or questions
arising under this Indenture or under any supplemental indenture as the Board of
Directors may deem necessary or desirable and which shall not adversely affect
the interests of the Holders of the Securities in any material respect;

                                       47
<PAGE>

     (c) to establish the form or terms of Securities of any series as permitted
by Sections 2.01 and 2.03;

     (d) to evidence and provide for the acceptance of appointment hereunder by
a successor trustee with respect to the Securities of one or more series and to
add to or change any of the provisions of this Indenture as shall be necessary
to provide for or facilitate the administration of the trusts hereunder by more
than one trustee, pursuant to the requirements of Section 5.10;

     (e) to comply with any requirements of the Commission in connection with
the qualification of this Indenture under the Trust Indenture Act of 1939;

     (f) to provide for uncertificated or Unregistered Securities and to make
all appropriate changes for such purpose;

     (g) to make any change that does not adversely affect the rights of any
Holder;

     (h) as provided by or pursuant to a Board Resolution or indenture
supplemental hereto establishing the terms of one or more series of Securities;

     (i) to add to the covenants of the Issuer such new covenants, restrictions,
conditions or provisions as its Board of Directors shall consider to be for the
protection of the Holders of Securities, and with respect to which the Trustee
has received an Opinion of Counsel to a similar effect, and to make the
occurrence, or the occurrence and continuance, of a default in any such
additional covenants, restrictions, conditions or provisions an Event of
Default; provided, that in respect of any such additional covenant, restriction,
condition or provision such supplemental indenture may provide for a particular
period of grace after default (which period may be shorter or longer than that
allowed in the case of other defaults) or may provide for an immediate
enforcement upon such an Event of Default or may limit the remedies available to
the Trustee upon such an Event of Default or may limit the right of the Holders
of a majority in aggregate principal amount of the Securities of such series to
waive such an Event of Default; or

     (j) to make any change so long as no Securities are Outstanding.

     The Trustee is hereby authorized to join with the Issuer in the execution
of any such supplemental indenture, to make any further appropriate agreements
and stipulations which may be therein contained and to accept the conveyance,
transfer, assignment, mortgage or pledge of any property thereunder, but the
Trustee shall not be obligated to enter into any such supplemental indenture
which affects the Trustee's own rights, duties or immunities under this
Indenture or otherwise.

                                       48
<PAGE>

     Any supplemental indenture authorized by the provisions of this section may
be executed without the consent of the Holders of any of the Securities at the
time outstanding, notwithstanding any of the provisions of Section 7.02.

     Section 7.02. Supplemental Indentures With Consent of Securityholders. With
the consent (evidenced as provided in Article 6) of the Holders of not less than
a majority in aggregate principal amount of the Securities at the time
Outstanding of all series affected by such supplemental indenture (voting as one
class), the Issuer, when authorized by a resolution of its Board of Directors,
and the Trustee may, from time to time and at any time, enter into an indenture
or indentures supplemental hereto for the purpose of adding any provisions to or
changing in any manner or eliminating any of the provisions of this Indenture or
of any supplemental indenture or of modifying in any manner the rights of the
Holders of the Securities of each such series; provided, that no such
supplemental indenture shall without the consent of each Holder affected
thereby:

          (i) change the stated maturity of the Principal of, or any sinking
     fund obligation or any installment of interest on, such Holder's Security;

          (ii) reduce the Principal thereof or the rate of interest thereon, or
     any premium payable with respect thereto;

          (iii) change any place of payment where, or the currency in which, any
     Security or any premium or the interest thereon is payable;

          (iv) change the provisions for calculating the optional redemption
     price, including the definitions relating thereto;

          (v) make any change to Section 4.07 or 4.10 (except to include other
     provisions subject to Section 4.10);

          (vi) reduce the percentage in principal amount of outstanding
     Securities of the relevant series the consent of whose Holders is required
     for any such supplemental indenture, for any waiver of compliance with any
     provisions of this Indenture or any defaults and their consequences
     provided for in this Indenture;

          (vii) alter or impair the right to convert any Security at the rate
     and upon the terms provided in Article 13;

          (viii) waive a default in the payment of Principal of or interest on
     any Security of such Holder (except pursuant to a rescission of
     acceleration pursuant to Section 4.01);

                                       49
<PAGE>

          (ix) adversely affect the rights of such Holder under any mandatory
     redemption or repurchase provision or any right of redemption or repurchase
     at the option of such Holder;

          (x) modify any of the provisions of this Section 7.02, except to
     increase any such percentage or to provide that certain other provisions of
     this Indenture cannot be modified or waived without the consent of the
     Holder of each outstanding Security affected thereby; or

          (xi) change or waive any provision that, pursuant to a board
     resolution or indenture supplemental hereto establishing the terms of one
     or more series of Securities, is prohibited to be so changed or waived.

     Upon the written request of the Issuer, accompanied by a copy of a
resolution of the Board of Directors certified by the secretary or an assistant
secretary of the Issuer authorizing the execution of any such supplemental
indenture, and upon the filing with the Trustee of evidence of the consent of
Securityholders as aforesaid and other documents, if any, required by Section
6.01, the Trustee shall join with the Issuer in the execution of such
supplemental indenture unless such 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 supplemental indenture.

     It shall not be necessary for the consent of the Securityholders under this
section to approve the particular form of any proposed supplemental indenture,
but it shall be sufficient if such consent shall approve the substance thereof.

     Promptly after the execution by the Issuer and the Trustee of any
supplemental indenture pursuant to the provisions of this Section, the Issuer
shall mail a notice thereof by first class mail to the Holders of Securities of
each series affected thereby at their addresses as they shall appear on the
registry books of the Issuer, setting forth in general terms the substance of
such supplemental indenture. Any failure of the Issuer to mail such notice, or
any defect therein, shall not, however, in any way impair or affect the validity
of any such supplemental indenture.

     Section 7.03. Effect of Supplemental Indenture. Upon the execution of any
supplemental indenture pursuant to the provisions hereof, this Indenture shall
be and be deemed to be modified and amended in accordance therewith and the
respective rights, limitations of rights, obligations, duties and immunities
under this Indenture of the Trustee, the Issuer and the Holders of Securities of
each series affected thereby shall thereafter be determined, exercised and
enforced hereunder subject in all respects to such modifications and amendments,
and all the terms and conditions of any such supplemental indenture shall be and
be

                                       50
<PAGE>

deemed to be part of the terms and conditions of this Indenture for any and
all purposes.

     Section 7.04. Documents to Be Given to Trustee. The Trustee, subject to the
provisions of Sections 5.01 and 5.02, may receive an Officers' Certificate and
an Opinion of Counsel as conclusive evidence that any supplemental indenture
executed pursuant to this Article 7 complies with the applicable provisions of
this Indenture.

     Section 7.05. Notation on Securities in Respect of Supplemental Indentures.
Securities of any series authenticated and delivered after the execution of any
supplemental indenture pursuant to the provisions of this Article may bear a
notation in form approved by the Trustee for such series as to any matter
provided for by such supplemental indenture or as to any action taken at any
such meeting. If the Issuer or the Trustee shall so determine, new Securities of
any series so modified as to conform, in the opinion of the Trustee and the
Board of Directors, to any modification of this Indenture contained in any such
supplemental indenture may be prepared by the Issuer, authenticated by the
Trustee and delivered in exchange for the Securities of such series then
outstanding.

                                   Article 8
                    CONSOLIDATION, MERGER, SALE OR CONVEYANCE

     Section 8.01. Issuer May Consolidate, etc., on Certain Terms. The Issuer
covenants that it will not merge or consolidate with any other Person or sell,
convey, transfer, lease or otherwise dispose of all or substantially all of its
property and assets to any Person (other than a consolidation with or merger
with or into or a sale, conveyance, transfer, lease or other disposition to a
Wholly-Owned Subsidiary with a positive net worth; provided that, in connection
with any such merger of the Issuer with a Wholly-Owned Subsidiary, no
consideration (other than common stock) in the surviving person or the Issuer
shall be issued or distributed to the stockholders of the Issuer), unless (i)
either (x) the Issuer shall be the continuing corporation, or the successor
corporation or (y) the Person formed by such consolidation or into which the
Issuer is merged or that acquires by sale or conveyance substantially all the
assets of the Issuer (if other than the Issuer) shall be a corporation or
limited liability company organized and validly existing under the laws of the
United States of America or any jurisdiction thereof and shall expressly assume
the due and punctual payment of the principal of and interest on all the
Securities, according to their tenor, and the due and punctual performance and
observance of all of the covenants and conditions of this Indenture to be
performed or observed by the Issuer, by supplemental indenture satisfactory to
the Trustee, executed and delivered to the Trustee by such Person, (ii)
immediately after giving effect to such transaction, no default or Event of

                                       51
<PAGE>

Default shall have occurred and be continuing and (iii) the Issuer delivers to
the Trustee an Officers' Certificate and Opinion of Counsel, in each case
stating that such consolidation, merger or transfer and such supplemental
indenture complies with this Section 8.01 and that all conditions precedent
provided for herein relating to such transaction have been complied with;
provided, however, that the foregoing limitations shall not apply if, in the
good faith determination of the Board of Directors, whose determination shall be
evidenced by a board resolution certified to the Trustee, the principal purpose
of such transaction is to change the state of incorporation of the Issuer; and
provided further that any such transaction shall not have as one of its purposes
the evasion of the foregoing limitations.

     Section 8.02. Successor Corporation Substituted. In case of any such
consolidation, merger, sale, conveyance, transfer, lease or other disposition,
and following such an assumption by the successor Person, such successor Person
shall succeed to and be substituted for the Issuer, with the same effect as if
it had been named herein. Such successor Person may cause to be signed, and may
issue either in its own name or in the name of the Issuer prior to such
succession any or all of the Securities issuable hereunder which theretofore
shall not have been signed by the Issuer and delivered to the Trustee; and, upon
the order of such successor Person instead of the Issuer and subject to all the
terms, conditions and limitations in this Indenture prescribed, the Trustee,
pursuant to the terms hereof, shall authenticate and shall deliver any
Securities which previously shall have been signed and delivered by the officers
of the Issuer to the Trustee for authentication, and any Securities which such
successor Person thereafter shall cause to be signed and delivered to the
Trustee for that purpose. All of the Securities so issued shall in all respects
have the same legal rank and benefit under this Indenture as the Securities
theretofore or thereafter issued in accordance with the terms of this Indenture
as though all of such Securities had been issued at the date of the execution
hereof.

     In case of any such consolidation, merger, sale, conveyance transfer, lease
or other disposition, such changes in phraseology and form (but not in
substance) may be made in the Securities thereafter to be issued as may be
appropriate.

     Upon the assumption by the successor Person in the manner described in this
Article, the Issuer shall be discharged from all obligations and covenants under
this Indenture and the Securities.

Cable Guarantees with respect to Securities of such series and this Indenture
with respect to Securities of such series if:

          (i) all Securities of such series previously authenticated and
     delivered (other than destroyed, lost or wrongfully taken Securities of
     such series that have been replaced or Securities of such series that are
     paid pursuant to Section 3.01 or Securities of such series for whose
     payment money or securities have theretofore been held in trust and
     thereafter repaid to the Issuer, as provided in Section 9.05) have been
     delivered to the Trustee for cancellation and the Issuer has paid all sums
     payable by it hereunder; or

          (ii) (A) Bookmark not defined. the Securities of such series mature
     within one year or all of them are to be called for redemption within one

     in trust with the Trustee, as trust funds solely for the benefit of the
     Holders of such Securities for that purpose, money or U.S. Government
     Obligations or a combination thereof sufficient (unless such funds consist
     solely of money, in the opinion of a nationally recognized firm of
     independent public accountants expressed in a written certification thereof
     delivered to the Trustee), without consideration of any reinvestment and
     after payment of all Federal, state and local taxes or other charges and
     assessments in respect thereof payable by the Trustee, to pay Principal of

     series have been complied with.

obligations in Sections 2.03 through 2.11, 3.02, 5.06, 5.09 and 9.05 in respect
of the Securities of such series shall survive until such Securities of such
series are no longer outstanding. Thereafter, only the Issuer's obligations in
Sections 5.06 and 9.05 in respect of the Securities of such series shall
survive. After any such irrevocable deposit, the Trustee shall acknowledge in
writing the discharge of the Issuer's obligations under the Securities of such
series and this Indenture with respect to the Securities of such series except
for those surviving obligations specified above.

     Section 9.02. Defeasance. Except as provided below, the Issuer will be
deemed to have paid and will be discharged from any and all obligations in
respect of the Securities of any series and the provisions of this Indenture and

<PAGE>

Cable Guarantees will no longer be in effect with respect to the Securities
of such series (and the Trustee, at the expense of the Issuer, shall execute
instruments in form and substance satisfactory to the Issuer and the Trustee
acknowledging the same); provided that the following conditions shall have been
satisfied:

          (i) the Issuer has irrevocably deposited in trust with the Trustee as
     trust funds specifically pledged as security for, and dedicated solely to,
     Holders of the Securities of such series, for payment of the Principal of
     and interest on the Securities of such series, money or U.S. Government
     Obligations or a combination thereof sufficient (unless such funds consist
     solely of money, in the opinion of a nationally recognized firm of
     independent public accountants expressed in a written certification thereof
     delivered to the Trustee) without consideration of any reinvestment and
     after payment of all Federal, state and local taxes or other charges and
     assessments in respect thereof payable by the Trustee, to pay and discharge
     the Principal of and accrued interest on the outstanding Securities of such
     series to maturity or earlier redemption (irrevocably provided for under
     arrangements satisfactory to the Trustee), as the case may be;

          (ii) such deposit will not result in a breach or violation of, or
     constitute a default under, this Indenture, the Cable Guarantees or any
     other material agreement or instrument to which the Issuer is a party or by
     which it is bound;

          (iii) no default or Event of Default with respect to the Securities of
     such series shall have occurred and be continuing on the date of such
     deposit;

          (iv) the Issuer shall have delivered to the Trustee (1) either (x) a
     ruling directed to the Trustee received from the Internal Revenue Service
     to the effect that the Holders of the Securities of such series will not
     recognize income, gain or loss for Federal income tax purposes as a result
     of the Issuer's exercise of its option under this Section 9.02 and will be
     subject to federal income tax on the same amount and in the same manner and
     at the same times as would have been the case if such deposit and
     defeasance had not occurred or (y) an Opinion of Counsel to the same effect
     as the ruling described in clause (x) above and based upon a change in law
     and (2) an Opinion of Counsel to the effect that the Holders of the
     Securities of such series have a valid security interest in the trust funds
     subject to no prior liens under the UCC; and

          (v) the Issuer has delivered to the Trustee an Officers' Certificate
     and an Opinion of Counsel, in each case stating that all conditions
     precedent provided for herein relating to the defeasance

                                       54
<PAGE>

     contemplated by this Section 9.02 of the Securities of such series have
     been complied with.

     The Issuer's obligations in Sections 2.03 through 2.11, 3.02, 5.06, 5.09
and 9.05 with respect to the Securities of such series shall survive until such
Securities are no longer outstanding. Thereafter, only the Issuer's obligations
in Sections 5.06 and 9.05 shall survive.

     Section 9.03. Covenant Defeasance. The Issuer may omit to comply with any
term, provision or condition set forth in Sections 3.04, 3.08, 3.10 or 3.11 (or
any other specific covenant relating to the Securities of any series provided
for in a Board Resolution or supplemental indenture pursuant to Section 2.03
which may by its terms be defeased pursuant to this Section 9.03), and such
omission shall be deemed not to be an Event of Default under clause (c) of
Section 4.01, respect to the outstanding Securities of such series if:

          (i) the Issuer has irrevocably deposited in trust with the Trustee as
     trust funds solely for the benefit of the Holders of the Securities of such
     series, for payment of the Principal of and interest, if any, on the
     Securities of such series, money or U.S. Government Obligations or a
     combination thereof in an amount sufficient (unless such funds consist
     solely of money, in the opinion of a nationally recognized firm of
     independent public accountants expressed in a written certification thereof
     delivered to the Trustee) without consideration of any reinvestment and
     after payment of all Federal, state and local taxes or other charges and
     assessments in respect thereof payable by the Trustee, to pay and discharge
     the Principal of and interest on the outstanding Securities of such series
     to maturity or earlier redemption (irrevocably provided for under
     arrangements satisfactory to the Trustee), as the case may be;

          (ii) such deposit will not result in a breach or violation of, or
     constitute a default under, this Indenture, the Cable Guarantees or any
     other material agreement or instrument to which the Issuer is a party or by
     which it is bound;

          (iii) no default or Event of Default with respect to the Securities of
     such series shall have occurred and be continuing on the date of such
     deposit;

          (iv) the Issuer has delivered to the Trustee an Opinion of Counsel to
     the effect that (A) the Holders of the Securities of such series have a
     valid security interest in the trust funds subject to no prior liens under
     the UCC and (B) such Holders will not recognize income, gain or loss for
     Federal income tax purposes as a result of such deposit and covenant
     defeasance and will be subject to Federal income tax on the same

                                       55
<PAGE>

     amount and in the same manner and at the same times as would have been the
     case if such deposit and defeasance had not occurred; and

          (v) the Issuer has delivered to the Trustee an Officers' Certificate
     and an Opinion of Counsel, in each case stating that all conditions
     precedent provided for herein relating to the covenant defeasance
     contemplated by this Section 9.03 of the Securities of such series have
     been complied with.

     Section 9.04. Application of Trust Money. Subject to Section 9.05, the
Trustee or Paying Agent shall hold in trust money or U.S. Government Obligations
deposited with it pursuant to Section 9.01, 9.02 or 9.03, as the case may be, in
respect of the Securities of any series and shall apply the deposited money and
the proceeds from deposited U.S. Government Obligations in accordance with the
Securities of such series and this Indenture to the payment of Principal of and
interest on the Securities of such series; but such money need not be segregated
from other funds except to the extent required by law. The Issuer shall pay and
indemnify the Trustee against any tax, fee or other charge imposed on or
assessed against the U.S. Government Obligations deposited pursuant to Section
9.01, 9.02 or 9.03, as the case may be, or the principal and interest received
in respect thereof, other than any such tax, fee or other charge that by law is
for the account of the Holders.

     Section 9.05. Repayment to Issuer. Subject to Sections 5.06, 9.01, 9.02 and
9.03, the Trustee and the Paying Agent shall promptly pay to the Issuer upon
request set forth in an Officers' Certificate any money held by them at any time
and not required to make payments hereunder and thereupon shall be relieved from
all liability with respect to such money. Subject to applicable escheat or
abandoned property laws, the Trustee and the Paying Agent shall pay to the
Issuer upon written request any money held by them and required to make payments
hereunder under this Indenture that remains unclaimed for two years; provided
that the Trustee or such Paying Agent before being required to make any payment
shall cause to be published at the expense of the Issuer once in an Authorized
Newspaper or mail to each Holder entitled to such money at such Holder's address
(as set forth in the register) notice that such money remains unclaimed and that
after a date specified therein (which shall be at least 30 days from the date of
such publication or mailing) any unclaimed balance of such money then remaining
will be repaid to the Issuer. After payment to the Issuer, Holders entitled to
such money must look to the Issuer for payment as unsecured general creditors
unless an abandoned property law designates another Person, and all liability of
the Trustee and such Paying Agent with respect to such money shall cease.

                            MISCELLANEOUS PROVISIONS

     Section 10.01. Incorporators, Stockholders, Officers and Directors Exempt
from Individual Liability. No recourse under or upon any obligation, covenant or
agreement contained in this Indenture, the Cable Guarantees or in any Security,
or because of any indebtedness evidenced thereby, shall be had against any
incorporator, as such, or against any past, present or future stockholder,
officer, director or employee, as such, of the Issuer, any Cable Guarantor or of
any successor Person thereof, either directly or through the Issuer or any Cable
Guarantor or any successor Person thereof, under any rule of law, statute or
constitutional provision or by the enforcement of any assessment or by any legal
or equitable proceeding or otherwise, all such liability being expressly waived
and released by the acceptance of the Securities by the holders thereof and as
part of the consideration for the issue of the Securities.

     Section 10.02. Provisions of Indenture for the Sole Benefit of Parties and
Securityholders. Nothing in this Indenture or in the Securities, expressed or
implied, shall give or be construed to give to any person, firm or corporation,
other than the parties hereto and their successors and the Holders of the
Securities, any legal or equitable right, remedy or claim under this Indenture
or under any covenant or provision herein contained, all such covenants and
provisions being for the sole benefit of the parties hereto and their successors
and of the Holders of the Securities.

     Section 10.03. Successors and Assigns of Issuer Bound by Indenture. All the
covenants, stipulations, promises and agreements in this Indenture contained by
or in behalf of the Issuer shall bind its successors and assigns, whether so
expressed or not.

     Section 10.04. Notices and Demands on Issuer, Trustee and Securityholders.
Any notice or demand which by any provision of this Indenture is required or
permitted to be given or served by the Trustee or by the Holders of Securities
to or on the Issuer may be given or served by being deposited postage prepaid,
first-class mail (except as otherwise specifically provided herein) addressed
(until another address of the Issuer is filed by the Issuer with the Trustee) to
Comcast Corporation at 1500 Market Street, Philadelphia, Pennsylvania
19102-2148, Attention: Treasurer. Any notice, direction, request or demand by
the Issuer or any Securityholder to or upon the Trustee shall be deemed to have
been sufficiently given or made, for all purposes, if given or made at the
Corporate Trust Office.

     Where this Indenture provides for notice to Holders, such notice shall be
sufficiently given (unless otherwise herein expressly provided) if in writing
and mailed, first-class postage prepaid, to each Holder entitled thereto, at his
last

                                       57
<PAGE>

address as it appears in the Security register. In any case where notice to
Holders is given by mail, neither the failure to mail such notice, nor any
defect in any notice so mailed, to any particular Holder shall affect the
sufficiency of such notice with respect to other Holders. Where this Indenture
provides for notice in any manner, such notice may be waived in writing by the
person entitled to receive such notice, either before or after the event, and
such waiver shall be the equivalent of such notice. Waivers of notice by Holders
shall be filed with the Trustee, but such filing shall not be a condition
precedent to the validity of any action taken in reliance upon such waiver.

     In case, by reason of the suspension of or irregularities in regular mail
service, it shall be impracticable to mail notice to the Issuer and
Securityholders when such notice is required to be given pursuant to any
provision of this Indenture, then any manner of giving such notice as shall be
satisfactory to the Trustee shall be deemed to be a sufficient giving of such
notice.

     Section 10.05. Officers' Certificates and Opinions of Counsel; Statements
to Be Contained Therein. Upon any application or demand by the Issuer to the
Trustee to take any action under any of the provisions of this Indenture, the
Issuer shall furnish to the Trustee an Officers' Certificate stating that all
conditions precedent provided for in this Indenture relating to the proposed
action have been complied with and an Opinion of Counsel stating that in the
opinion of such counsel all such conditions precedent have been complied with,
except that in the case of any such application or demand as to which the
furnishing of such documents is specifically required by any provision of this
Indenture relating to such particular application or demand, no additional
certificate or opinion need be furnished.

     Each certificate or opinion provided for in this Indenture and delivered to
the Trustee with respect to compliance with a condition or covenant provided for
in this Indenture shall include (a) a statement that the person making such
certificate or opinion has read such covenant or condition, (b) a brief
statement as to the nature and scope of the examination or investigation upon
which the statements or opinions contained in such certificate or opinion are
based, (c) a statement that, in the opinion of such person, he has made such
examination or investigation as is necessary to enable him to express an
informed opinion as to whether or not such covenant or condition has been
complied with and (d) a statement as to whether or not, in the opinion of such
person, such condition or covenant has been complied with.

     Any certificate, statement or opinion of an officer of the Issuer may be
based, insofar as it relates to legal matters, upon a certificate or opinion of
or representations by counsel, unless such officer knows that the certificate or
opinion or representations with respect to the matters upon which his
certificate, statement or opinion may be based as aforesaid are erroneous, or in
the exercise

                                       58
<PAGE>

of reasonable care should know that the same are erroneous. Any certificate,
statement or opinion of counsel may be based, insofar as it relates to factual
matters, information with respect to which is in the possession of the Issuer,
upon the certificate, statement or opinion of or representations by an officer
of officers of the Issuer, unless such counsel knows that the certificate,
statement or opinion or representations with respect to the matters upon which
his certificate, statement or opinion may be based as aforesaid are erroneous,
or in the exercise of reasonable care should know that the same are erroneous.

     Any certificate, statement or opinion of an officer of the Issuer or of
counsel may be based, insofar as it relates to accounting matters, upon a
certificate or opinion of or representations by an accountant or firm of
accountants in the employ of the Issuer, unless such officer or counsel, as the
case may be, knows that the certificate or opinion or representations with
respect to the accounting matters upon which his certificate, statement or
opinion may be based as aforesaid are erroneous, or in the exercise of
reasonable care should know that the same are erroneous.

         Any certificate or opinion of any independent firm of public
accountants filed with the Trustee shall contain a statement that such firm is
independent.

     Section 10.06. Payments Due on Saturdays, Sundays and Holidays. If the date
of maturity of interest on or principal of the Securities of any series or the
date fixed for redemption or repayment of any such Security shall not be a
Business Day, then payment of interest or principal need not be made on such
date, but may be made on the next succeeding Business Day with the same force
and effect as if made on the date of maturity or the date fixed for redemption,
and no interest shall accrue for the period after such date.

     Section 10.07. Conflict of Any Provision of Indenture with Trust Indenture
Act of 1939. If and to the extent that any provision of this Indenture limits,
qualifies or conflicts with another provision included in this Indenture by
operation of Sections 310 to 317, inclusive, of the Trust Indenture Act of 1939
(an "incorporated provision"), such incorporated provision shall control.

     Section 10.08. New York Law to Govern. This Indenture, including any Cable
Guarantee, and each Security shall be deemed to be a contract under the laws of
the State of New York, and for all purposes shall be construed in accordance
with the laws of such State.

     Section 10.09. Counterparts. This Indenture may be executed in any number
of counterparts, each of which shall be an original; but such counterparts shall
together constitute but one and the same instrument.

     Section 10.10. Effect of Headings. The Article and Section headings herein
and the Table of Contents are for convenience only and shall not affect the
construction hereof.

                                   Article 11
                   REDEMPTION OF SECURITIES AND SINKING FUNDS

     Section 11.01. Applicability of Article. The provisions of this Article
shall be applicable to the Securities of any series which are redeemable before
their maturity or to any sinking fund for the retirement of Securities of a
series except as otherwise specified as contemplated by Section 2.03 for
Securities of such series.

     Section 11.02. Notice of Redemption; Partial Redemptions. Notice of
redemption to the Holders of Securities of any series to be redeemed as a whole
or in part at the option of the Issuer shall be given by mailing notice of such
redemption by first class mail, postage prepaid, at least 30 days and not more
than 60 days prior to the date fixed for redemption to such Holders of
Securities of such series at their last addresses as they shall appear upon the
registry books. Any notice which is mailed in the manner herein provided shall
be conclusively presumed to have been duly given, whether or not the Holder
receives the notice. Failure to give notice by mail, or any defect in the notice
to the Holder of any Security of a series designated for redemption as a whole
or in part shall not affect the validity of the proceedings for the redemption
of any other Security of such series.

     The notice of redemption to each such Holder shall specify the CUSIP
numbers of such Securities to be redeemed, the principal amount of each Security
of such series held by such Holder to be redeemed, the date fixed for
redemption, the redemption price, the place or places of payment, that payment
will be made upon presentation and surrender of such Securities, that such
redemption is pursuant to the mandatory or optional sinking fund, or both, if
such be the case, that interest accrued to the date fixed for redemption will be
paid as specified in such notice and that on and after said date interest
thereon or on the portions thereof to be redeemed will cease to accrue. In case
any Security of a series is to be redeemed in part only the notice of redemption
shall state the portion of the principal amount thereof to be redeemed, the
method the Trustee shall use to determine such Securities to be redeemed as
specified in the last paragraph of this Section 11.02, if applicable, and shall
state that on and after the date fixed for redemption, upon surrender of such
Security, a new Security or Securities of such series in principal amount equal
to the unredeemed portion thereof will be issued.

                                       60
<PAGE>

     The notice of redemption of Securities of any series to be redeemed at the
option of the Issuer shall be given by the Issuer or, at the Issuer's written
request, by the Trustee in the name and at the expense of the Issuer.

     By 10:00 a.m. (New York City time) on the redemption date specified in the
notice of redemption given as provided in this Section, the Issuer will deposit
with the Trustee or with one or more paying agents (or, if the Issuer is acting
as its own paying agent, set aside, segregate and hold in trust as provided in
Section 3.03) an amount of money sufficient to redeem on the redemption date all
the Securities of such series so called for redemption at the appropriate
redemption price, together with accrued interest to the date fixed for
redemption. If less than all the outstanding Securities of a series are to be
redeemed, the Issuer will deliver to the Trustee at least 70 days (unless a
shorter period shall be satisfactory to the Trustee) prior to the date fixed for
redemption an Officers' Certificate stating the aggregate principal amount of
Securities to be redeemed.

     In the case of the redemption of all of the Securities of a series
outstanding, the Issuer shall notify the Trustee in writing of the redemption
date 45 days (unless a shorter period shall be satisfactory to the Trustee)
prior to the redemption date.

     If less than all the Securities of a series are to be redeemed, the Trustee
shall select, pro rata or by lot or in such manner as it shall deem appropriate
and fair, Securities of such series to be redeemed in whole or in part.
Securities of a series may be redeemed in part in multiples equal to the minimum
authorized denomination for Securities of such series or any multiple thereof.
The Trustee shall promptly notify the Issuer in writing of the Securities of
such series selected for redemption and, in the case of any Securities of such
series selected for partial redemption, the principal amount thereof to be
redeemed. For all purposes of this Indenture, unless the context otherwise
requires, all provisions relating to the redemption of Securities of any series
shall relate, in the case of any Security redeemed or to be redeemed only in
part, to the portion of the principal amount of such Security which has been or
is to be redeemed.

     Section 11.03. Payment of Securities Called for Redemption. If notice of
redemption has been given as above provided, the Securities or portions of
Securities specified in such notice shall become due and payable on the date and
at the place stated in such notice at the applicable redemption price, together
with interest accrued to the date fixed for redemption, and on and after said
date (unless the Issuer shall default in the payment of such Securities at the
redemption price, together with interest accrued to said date) interest on the
Securities or portions of Securities so called for redemption shall cease to
accrue and, except as provided in Sections 5.05 and 9.04, such Securities shall
cease from and after the date fixed for redemption to be entitled to any benefit
or security under this Indenture, and the Holders thereof shall have no right in
respect of such Securities

                                       61
<PAGE>

except the right to receive the redemption price thereof and unpaid interest to
the date fixed for redemption. On presentation and surrender of such Securities
at a place of payment specified in said notice, said Securities or the specified
portions thereof shall be paid and redeemed by the Issuer at the applicable
redemption price, together with interest accrued thereon to the date fixed for
redemption; provided that any semiannual payment of interest becoming due on the
date fixed for redemption shall be payable to the Holders of such Securities
registered as such on the relevant record date subject to the terms and
provisions of Section 2.07 hereof.

     If any Security called for redemption shall not be so paid upon surrender
thereof for redemption, the principal shall, until paid or duly provided for,
bear interest from the date fixed for redemption at the rate of interest or
Yield to Maturity (in the case of an Original Issue Discount Security) borne by
the Security.

     Upon presentation of any Security redeemed in part only, the Issuer shall
execute and the Trustee shall authenticate and deliver to or on the order of the
Holder thereof, at the expense of the Issuer, a new Security or Securities of
such series, of authorized denominations, in principal amount equal to the
unredeemed portion of the Security so presented pursuant to Sections 2.04, 2.05
and 2.06.

     Section 11.04. Exclusion of Certain Securities from Eligibility for
Selection for Redemption. Securities shall be excluded from eligibility for
selection for redemption if they are identified by registration and certificate
number in a written statement signed by an authorized officer of the Issuer and
delivered to the Trustee at least 40 days prior to the last date on which notice
of redemption may be given as being owned of record and beneficially by, and not
pledged or hypothecated by either (a) the Issuer or (b) an entity specifically
identified in such written statement directly or indirectly controlling or
controlled by or under direct or indirect common control with the Issuer.

     Section 11.05. Mandatory and Optional Sinking Funds. The minimum amount of
any sinking fund payment provided for by the terms of Securities of any series
is herein referred to as a "mandatory sinking fund payment", and any payment in
excess of such minimum amount provided for by the terms of Securities of any
series is herein referred to as an "optional sinking fund payment". The date on
which a sinking fund payment is to be made is herein referred to as the "sinking
fund payment date".

     In lieu of making all or any part of any mandatory sinking fund payment
with respect to any series of Securities in cash, the Issuer may at its option
(a) deliver to the Trustee Securities of such series theretofore purchased or
otherwise acquired (except upon redemption pursuant to the mandatory sinking
fund) by the Issuer or receive credit for Securities of such series (not
previously so credited)

                                       62
<PAGE>

theretofore purchased or otherwise acquired (except as aforesaid) by the Issuer
and delivered to the Trustee for cancellation pursuant to Section 2.10, (b)
receive credit for optional sinking fund payments (not previously so credited)
made pursuant to this Section, or (c) receive credit for Securities of such
series (not previously so credited) redeemed by the Issuer through any optional
redemption provision contained in the terms of such series. Securities so
delivered or credited shall be received or credited by the Trustee at the
sinking fund redemption price specified in such Securities.

     On or before the sixtieth day next preceding each sinking fund payment date
for any series, the Issuer will deliver to the Trustee an Officers' Certificate
(a) specifying the portion of the mandatory sinking fund payment to be satisfied
by payment of cash and the portion to be satisfied by credit of Securities of
such series, (b) stating that none of the Securities of such series has
theretofore been so credited, (c) stating that no defaults in the payment of
interest or Events of Default with respect to such series have occurred (which
have not been waived or cured) and are continuing and (d) stating whether or not
the Issuer intends to exercise its right to make an optional sinking fund
payment with respect to such series and, if so, specifying the amount of such
optional sinking fund payment which the Issuer intends to pay on or before the
next succeeding sinking fund payment date. Any Securities of such series to be
credited and required to be delivered to the Trustee in order for the Issuer to
be entitled to credit therefor as aforesaid which have not theretofore been
delivered to the Trustee shall be delivered for cancellation pursuant to Section
2.10 to the Trustee with such written statement (or reasonably promptly
thereafter if acceptable to the Trustee). Such Officers' Certificate shall be
irrevocable and upon its receipt by the Trustee the Issuer shall become
unconditionally obligated to make all the cash payments or payments therein
referred to, if any, on or before the next succeeding sinking fund payment date.
Failure of the Issuer, on or before any such sixtieth day, to deliver such
written statement and Securities specified in this paragraph, if any, shall not
constitute a default but shall constitute, on and as of such date, the
irrevocable election of the Issuer (i) that the mandatory sinking fund payment
for such series due on the next succeeding sinking fund payment date shall be
paid entirely in cash without the option to deliver or credit Securities of such
series in respect thereof and (ii) that the Issuer will make no optional sinking
fund payment with respect to such series as provided in this Section.

     If any sinking fund payment or payments (mandatory or optional or both) to
be made in cash on the next succeeding sinking fund payment date plus any unused
balance of any preceding sinking fund payments made in cash shall exceed $50,000
(or a lesser sum if the Issuer shall so request in writing) with respect to the
Securities of any particular series, such cash shall be applied on the next
succeeding sinking fund payment date to the redemption of Securities of such
series at the sinking fund redemption price together with accrued interest to
the date fixed for redemption. If such amount shall be $50,000 or less and the

                                       63
<PAGE>

Issuer makes no such request then it shall be carried over until a sum in excess
of $50,000 is available together with accrued interest to the date fixed for
redemption. The Trustee shall select, in the manner provided in Section 11.02,
for redemption on such sinking fund payment date a sufficient principal amount
of Securities of such series to absorb said cash, as nearly as may be, and shall
(if requested in writing by the Issuer) inform the Issuer of the serial numbers
of the Securities of such series (or portions thereof) so selected. Securities
of any series which are identified in an Officers' Certificate at least 60 days
prior to the sinking fund payment date as being beneficially owned by, and not
pledged or hypothecated by, the Issuer or an entity directly or indirectly
controlling or controlled by or under direct or indirect common control with the
Issuer shall be excluded from Securities of such series eligible for selection
for redemption. The Issuer or the Trustee, in the name and at the expense of the
Issuer (if the Issuer shall so request the Trustee in writing) shall cause
notice of redemption of the Securities of such series to be given in the manner
provided in Section 11.02 (and with the effect provided in Section 11.03) for
the redemption of Securities of such series in part at the option of the Issuer.
The amount of any sinking fund payments not so applied or allocated to the
redemption of Securities of such series shall be added to the next cash sinking
fund payment for such series and, together with such payment, shall be applied
in accordance with the provisions of this Section. Any and all sinking fund
moneys held on the stated maturity date of the Securities of any particular
series (or earlier, if such maturity is accelerated), which are not held for the
payment or redemption of particular Securities of such series shall be applied,
together with other moneys, if necessary, sufficient for the purpose, to the
payment of the principal of, and interest on, the Securities of such series at
maturity.

     At least one Business Day before each sinking fund payment date, the Issuer
shall pay to the Trustee in cash or shall otherwise provide for the payment of
all interest accrued to the date fixed for redemption on Securities to be
redeemed on the next following sinking fund payment date.

     The Trustee shall not redeem or cause to be redeemed any Securities of a
series with sinking fund moneys or mail any notice of redemption of Securities
for such series by operation of the sinking fund during the continuance of a
default in payment of interest on such Securities or of any Event of Default if
the Trustee has received written notice thereof at least three Business Days
prior to any payment hereunder except that, where the mailing of notice of
redemption of any Securities shall theretofore have been made, the Trustee shall
redeem or cause to be redeemed such Securities, provided that it shall have
received from the Issuer a sum sufficient for such redemption. Except as
aforesaid, if the Trustee has received written notice of such default or Event
of Default at least three Business Days prior to any payment hereunder, any
moneys in the sinking fund for such series at the time when any such default or
Event of Default shall occur, and any moneys thereafter paid into the sinking
fund, shall, during the

                                       64
<PAGE>

continuance of such default or Event of Default, be deemed to have been
collected under Article 4 and held for the payment of all such Securities. In
case such Event of Default shall have been waived as provided in Section 4.10 or
the default cured on or before the sixtieth day preceding the sinking fund
payment date in any year, such moneys shall thereafter be applied on the next
succeeding sinking fund payment date in accordance with this section to the
redemption of such Securities.

     Section 11.06. Conversion Arrangement on Call for Redemption. In connection
with any redemption of Securities, the Issuer shall deposit the amount due in
connection with such redemption as required by Section 11.02 or it may arrange
for the purchase and conversion of any Securities called for redemption by an
agreement with one or more investment bankers or other purchasers to purchase
such Securities and to make the deposit required of it by Section 11.02 on its
behalf by paying to the Trustee or the Paying Agent in trust for the
Securityholders, on or before 10:00 a.m. New York time on the redemption date,
an amount no less than the redemption price, together with interest, if any,
accrued to the redemption date of such Securities, in immediately available
funds. Notwithstanding anytime to the contrary contained in this Article 11, the
obligation of the Issuer to pay the redemption price of such Securities,
including all accrued interest, if any, shall be deemed to be satisfied and
discharged to the extent such amount is so paid by such purchasers. If such an
agreement is entered into, any Securities not duly surrendered for conversion by
the holders thereof may, at the option of the Issuer, be deemed, to the fullest
extent permitted by law, acquired by such purchasers from such holders and
(notwithstanding anything to the contrary contained in Article 13) surrendered
by such purchasers for conversion, all as of immediately prior to the close of
business on the last day on which Securities of such series called for
redemption may be converted in accordance with this Indenture and the terms of
such Securities, subject to payment of the above amount aforesaid. The Trustee
or the Paying Agent shall hold and pay to the Securityholders whose Securities
are selected for redemption any such amount paid to it in the same manner as it
would moneys deposited with it by the Issuer for the redemption of Securities.
Without the Trustee's and the Paying Agent's prior written consent, no
arrangement between the Issuer and such purchasers for the purchase and
conversion of any Securities shall increase or otherwise affect any of the
powers, duties, responsibilities or obligations of the Trustee as set forth in
this Indenture, and the Issuer agrees to indemnify the Trustee from, and hold it
harmless against, any loss, liability or expense arising out of or in connection
with any such arrangement for the purchase and conversion of any Securities
between the Issuer and such purchasers, including the costs and expenses
incurred by the Trustee and the Paying Agent in the defense of any claim or
liability arising out of or in connection with the exercise or performance of
any of its powers, duties, responsibilities or obligations under this Indenture.

                                   Article 12
                           SUBORDINATION OF SECURITIES

     Section 12.01. Agreement of Subordination. The Issuer covenants and agrees,
and each holder of Securities issued hereunder by his acceptance thereof
likewise covenants and agrees, that all Securities shall be issued subject to
the provisions of this Article 12; and each Securityholder, whether upon
original issue or upon transfer or assignment thereof, accepts and agrees to be
bound by such provisions.

     The payment of the principal of, premium, if any, and interest on all
Securities issued hereunder shall, to the extent and in the manner hereinafter
set forth, be subordinated and subject in right of payment to the prior payment
in full of all Senior Indebtedness, whether outstanding at the date of this
Indenture or thereafter incurred.

     The provisions of this Article 12 define the subordination of the
Securities, as obligations of the Company, with respect to Senior Indebtedness
of the Company, as defined for the Company. All such provisions shall also be
deemed to apply in the same way (mutatis mutandis) to each Cable Guarantor, with
appropriate corresponding references to the Senior Indebtedness of such Cable
Guarantor.

     No provision of this Article 12 shall prevent the occurrence of any default
or Event of Default hereunder.

     Section 12.02. Payments to Securityholders. In the event and during the
continuation of any default in the payment of principal, premium, interest or
any other payment due on any Senior Indebtedness of the Issuer continuing beyond
the period of grace, if any, specified in the instrument or lease evidencing
such Senior Indebtedness of the Issuer, then, unless and until such default
shall have been cured or waived or shall have ceased to exist, no payment shall
be made by the Issuer with respect to the principal of, or premium, if any, or
interest on the Securities, except sinking fund payments made by the acquisition
of Securities under Section 11.05 prior to the happening of such default and
payments made pursuant to Article 9 hereof from monies deposited with the
Trustee pursuant thereto prior to the happening of such default.

     Upon any payment by the Issuer, or distribution of assets of the Issuer of
any kind or character, whether in cash, property or securities, to creditors
upon any dissolution or winding-up or liquidation or reorganization of the
Issuer, whether voluntary or involuntary or in bankruptcy, insolvency,
receivership or other proceedings, all amounts due or to become due upon all
Senior Indebtedness of the Issuer shall first be paid in full, or payment
thereof provided for in money in accordance with its terms, before any payment
is made on account of the

                                       66
<PAGE>

principal (and premium, if any) or interest on the Securities (except payments
made pursuant to Article 9 hereof from monies deposited with the Trustee
pursuant thereto prior to the happening of such dissolution, winding-up,
liquidation or reorganization); and upon any such dissolution or winding-up or
liquidation or reorganization any payment by the Issuer, or distribution of
assets of the Issuer of and kind or character, whether in cash, property or
securities, to which the holders of the Securities or the Trustee would be
entitled, except for the provisions of this Article 12, shall (except as
aforesaid) be paid by the Issuer or by any receiver, trustee in bankruptcy,
liquidating trustee, agent or other Person making such payment or distribution,
or by the holders of the Securities or by the Trustee under this Indenture if
received by them or it, directly to the holders of Senior Indebtedness of the
Issuer (pro rata to such holders on the basis of the respective amounts of
Senior Indebtedness of the Issuer held by such holders, as calculated by the
Issuer) or their representative or representatives, or to the trustee or
trustees under any indenture pursuant to which any instruments evidencing any
Senior Indebtedness of the Issuer may have been issued, as their respective
interests may appear, to the extent necessary to pay all Senior Indebtedness of
the Issuer in full, in money or money's worth, after giving effect to any
concurrent payment or distribution to or for the holders of Senior Indebtedness
of the Issuer, before any payment or distribution is made to the holders of the
Securities or to the Trustee.

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

     For purposes of this Article 12, the words, "cash, property or securities"
shall not be deemed to include shares of stock of the Issuer as reorganized or
readjusted, or securities of the Issuer or any other corporation provided for by
a plan of reorganization or readjustment, the payment of which is subordinated
at least to the extent provided in this Article 12 with respect to the
Securities to the payment of all Senior Indebtedness of the Issuer which may at
the time be outstanding; provided that (i) the Senior Indebtedness of the Issuer
is assumed by

                                       67
<PAGE>

the new corporation, if any, resulting from any such reorganization or
readjustment, and (ii) the rights of the holders of the Senior Indebtedness of
the Issuer (other than leases) and of leases which are assumed are not, without
the consent of such holders, altered by such reorganization or readjustment. The
consolidation of the Issuer with, or the merger of the Issuer into, another
corporation or the liquidation or dissolution of the Issuer following the
conveyance or transfer of its property as an entirety, or substantially as an
entirety, to another corporation upon the terms and conditions provided for in
Article 8 hereof shall not be deemed a dissolution, winding-up, liquidation or
reorganization for the purposes of this Section 12.02 if such other corporation
shall, as a part of such consolidation, merger, conveyance or transfer, comply
with the conditions stated in Article 8 hereof. Nothing in this Section 12.02
shall apply to claims of, or payments to, the Trustee under or pursuant to
Section 5.06.

     Section 12.03. Subrogation of Securities. Subject to the payment in full of
all Senior Indebtedness of the Issuer, the rights of the holders of the
Securities shall be subrogated to the rights of the holders of Senior
Indebtedness of the Issuer to receive payments or distributions of cash,
property or securities of the Issuer applicable to the Senior Indebtedness of
the Issuer until the principal of (and premium, if any) and interest on the
Securities shall be paid in full; and, for the purposes of such subrogation, no
payments or distributions to the holders of the Senior Indebtedness of the
Issuer of any cash, property or securities to which the holders of the
Securities or the Trustee would be entitled except for the provisions of this
Article 12 no payment over pursuant to the provisions of this Article 12, to or
for the benefit of the holders of Senior Indebtedness of the Issuer by holders
of the Securities or the Trustee, shall, as between the Issuer, its creditors
other than holders of Senior Indebtedness of the Issuer, and the holders of the
Securities, be deemed to be a payment by the Issuer to or on account of the
Senior Indebtedness of the Issuer. It is understood that the provisions of this
Article 12 are and are intended solely for the purpose of defining the relative
rights of the holders of the Securities, on the one hand, and the holders of the
Senior Indebtedness of the Issuer, on the other hand.

     Nothing contained in this Article 12 or elsewhere in this Indenture or in
the Securities is intended to or shall impair, as between the Issuer, its
creditors other than the holders of its Senior Indebtedness, and the holders of
the Securities, the obligation of the Issuer, which is absolute and
unconditional, to pay to the holders of the Securities the principal of (and
premium, if any) and interest on the Securities as and when the same shall
become due and payable in accordance with their terms, or is intended to or
shall affect the relative rights of the holders of the Securities and creditors
of the Issuer other than the holders of its Senior Indebtedness, nor shall
anything herein or therein prevent the Trustee or the holder of any Security
from exercising all remedies otherwise permitted by applicable law upon default
under this Indenture, subject to the rights, if any, under this Article 12 of
the holders of Senior Indebtedness of the Issuer in respect

                                       68
<PAGE>

of cash, property or securities of the Issuer received upon the exercise of any
such remedy.

     Upon any payment or distribution of assets of the Issuer referred to in
this Article 12, the Trustee, subject to the provisions of Section 5.01, and the
holders of the Securities shall be entitled to rely upon any order or decree
made by any court of competent jurisdiction in which such dissolution,
winding-up, liquidation or reorganization proceedings are pending, or a
certificate of the receiver, trustee in bankruptcy, liquidating trustee, agent
or other Person making such payment or distribution, delivered to the Trustee or
to the holders of the Securities, for the purpose of ascertaining the Persons
entitled to participate in such distribution, the holders of the Senior
Indebtedness and other indebtedness of the Issuer, the amount thereof or payable
thereon, the amount or amounts paid or distributed thereon and all other facts
pertinent thereto or to this Article 12.

     Section 12.04. Authorization by Securityholders. Each holder of a Security
by his acceptance thereof authorizes and directs the Trustee in his behalf to
take such action as may be necessary or appropriate to effectuate the
subordination provided in this Article 12 appoints the Trustee his
attorney-in-fact for any and all such purposes.

     Section 12.05. Notice to Trustee. The Issuer shall give promptly written
notice to a Responsible Officer of the Trustee of any fact known to the Issuer
which would prohibit the making of any payment of monies to or by the Trustee in
respect of the Securities pursuant to the provisions of this Article 12.
Notwithstanding the provisions of this Article 12 or any other provision of this
Indenture, the Trustee shall not be charged with knowledge of the existence of
any facts which would prohibit the making of any payment of monies to or by the
Trustee in respect of the Securities pursuant to the provisions of this Article
12, unless and until a Responsible Officer of the Trustee shall have received
written notice thereof at the Corporate Trust Office of the Trustee from the
Issuer or a holder or holders of Senior Indebtedness or from any trustee
therefor; and before the receipt of any such written notice, the Trustee,
subject to the provisions of Section 5.01, shall be entitled in all respects to
assume that no such facts exist; provided that if on a date not fewer than three
Business Days prior to the date upon which by the terms hereof any such monies
may become payable for any purpose (including, without limitation, the payment
of the principal of (or premium, if any) or interest on any Security) the
Trustee shall not have received, with respect to such monies, the notice
provided for in this Section 12.05, then, anything herein contained to the
contrary notwithstanding, the Trustee shall have full power and authority to
receive such monies and to apply the same to the purpose for which they were
received, and shall not be affected by any notice to the contrary which may be
received by it on or after such prior date.

                                       69
<PAGE>

     Notwithstanding anything to the contrary hereinbefore set forth, nothing
shall prevent any payment by the Issuer or the Trustee to the Securityholders of
monies in connection with a redemption of Securities if (i) notice of such
redemption has been given pursuant to Article 11 or Section 9.01 hereof prior to
the receipt by the Trustee of written notice as aforesaid, and (ii) such notice
of redemption is given not earlier than 60 days before the redemption date.

     The Trustee conclusively shall be entitled to rely on the delivery to it of
a written notice by a Person representing himself to be a holder of Senior
Indebtedness of the Issuer (or a trustee on behalf of such holder) to establish
that such notice has been given by a holder of Senior Indebtedness of the Issuer
or a trustee on behalf of any such holder or holders. In the event that the
Trustee determines in good faith that further evidence is required with respect
to the right of any Person as a holder of Senior Indebtedness of the Issuer to
participate in any payment or distribution pursuant to this Article 12, the
Trustee may request such Person to furnish evidence to the reasonable
satisfaction of the Trustee as to the amount of Senior Indebtedness of the
Issuer held by such Person, the extent to which such Person is entitled to
participate in such payment or distribution and any other facts pertinent to the
rights of such Person under this Article 12, and if such evidence is not
furnished the Trustee may defer any payment to such Person pending judicial
determination as to the right of such Person to receive such payment.

     Section 12.06. Trustee's Relation to Senior Indebtedness. The Trustee in
its individual capacity shall be entitled to all the rights set forth in this
Article 12 in respect of any Senior Indebtedness of the Issuer at any time held
by it, to the same extent as any other holder of Senior Indebtedness of the
Issuer and nothing elsewhere in this Indenture shall deprive the Trustee of any
of its rights as such holder.

     With respect to the holders of Senior Indebtedness of the Issuer, the
Trustee undertakes to perform or to observe only such of its covenants and
obligations as are specifically set forth in this Article 12, and no implied
covenants or obligations with respect to the holders of Senior Indebtedness of
the Issuer shall be read into this Indenture against the Trustee. The Trustee
shall not be deemed to owe any fiduciary duty to the holders of Senior
Indebtedness of the Issuer and the Trustee shall not be liable to any holder of
Senior Indebtedness of the Issuer if it shall pay over or deliver to holders of
Securities, the Issuer or any other Person money or assets to which any holder
of Senior Indebtedness of the Issuer shall be entitled by virtue of this Article
12 or otherwise.

     Section 12.07. No Impairment of Subordination. No right of any present or
future holder of any Senior Indebtedness to enforce subordination as herein
provided shall at any time in any way be prejudiced or impaired by any act or
failure to act on the part of the Issuer or by any act or failure to act, in
good faith,

                                       70
<PAGE>

by any such holder, or by any noncompliance by the Issuer with the
terms, provisions and covenants of this Indenture, regardless of any knowledge
thereof which any such holder may have or otherwise be charge with.

     Section 12.08. Rights of Trustee. Nothing in this Article 12 shall apply to
claims of or payments to, the Trustee pursuant to Section 5.06 or 9.04.

                                   Article 13
                            CONVERSION OF SECURITIES

     SECTION 13.01. Applicability of Article. Securities of any series which are
convertible into Capital Stock at the option of the Securityholder shall be
convertible in accordance with their terms and (unless otherwise specified as
contemplated by Section 2.03 for Securities of any series) in accordance with
this Article. Each reference in this Article 13 to "a Security" or "the
Securities" refers to the Securities of the particular series that is
convertible into Capital Stock. Each reference in this Article to "Capital
Stock" into which Securities of any series are convertible refers to the class
of Capital Stock into which the Securities of such series are convertible in
accordance with their terms (as specified as contemplated by Section 2.03). If
more than one series of Securities with conversion privileges are outstanding at
any time, the provisions of this Article 13 shall be applied separately to each
such series.

     SECTION 13.02. Right of Securityholders to Convert Securities. Subject to
and upon compliance with the terms of the Securities and the provisions of
Section 11.06 and this Article 13, at the option of the holder thereof, any
Security of any series of any authorized denomination, or any portion of the
principal amount thereof which is $1,000 or any integral multiple of $1,000,
may, at any time during the period specified in the Securities of such series,
or in case such Security or portion thereof shall have been called for
redemption, then in respect of such Security or portion thereof until and
including, but not after (unless the Issuer shall default in payment due upon
the redemption thereof) the close of business on the Business Day prior to the
date fixed for redemption except that in the case of redemption at the option of
the Securityholder, if specified in the terms of such Securities, such right
shall terminate upon receipt of written notice of the exercise of such option,
be converted into duly authorized, validly issued, fully paid and nonassessable
shares of the class of Class A Common Stock and Class A Special Common Stock, or
combination thereof, as specified in such Security, at the conversion rate for
each $1,000 principal amount of Securities (such initial conversion rate
reflecting an initial conversion price specified in such Security) in effect on
the conversion date, or, in case an adjustment in the conversion rate has taken
place pursuant to the provisions of Section 13.05, then at the applicable
conversion rate as so adjusted, upon surrender of the Security or Securities,
the principal amount of which is so to be converted, to the Issuer at any time
during

                                       71
<PAGE>

usual business hours at the office or agency to be maintained by it in
accordance with the provisions of Section 3.02, accompanied by a written notice
of election to convert as provided in Section 13.03 and, if so required by the
Issuer and the Trustee, by a written instrument or instruments of transfer in
form satisfactory to the Issuer and the Trustee duly executed by the registered
holder or his attorney duly authorized in writing. All Securities surrendered
for conversion shall, if surrendered to the Issuer or any conversion agent, be
delivered to the Trustee for cancellation and cancelled by it, or shall, if
surrendered to the Trustee, be cancelled by it, as provided in Section 2.10.

     The initial conversion price or conversion rate in respect of a series of
Securities shall be as specified in the Securities of such series. The
conversion price or conversion rate will be subject to adjustment on the terms
set forth in Section 13.05 or such other or different terms, if any, as may be
specified by Section 2.03 for Securities of such series. Provisions of this
Indenture that apply to conversion of all of a Security also apply to conversion
of a portion of it.

     SECTION 13.03. Issuance of Shares of Capital Stock on Conversion. As
promptly as practicable after the surrender, as herein provided, of any Security
or Securities for conversion, the Issuer shall deliver or cause to be delivered
at its said office or agency to or upon the written order of the holder of the
Security or Securities so surrendered a certificate or certificates representing
the number of duly authorized, validly issued, fully paid and nonassessable
shares of Capital Stock into which such Security or Securities may be converted
in accordance with the terms thereof and the provisions of this Article 13.
Prior to delivery of such certificate or certificates, the Issuer shall require
a written notice at its said office or agency from the holder of the Security or
Securities so surrendered stating that the holder irrevocably elects to convert
such Security or Securities, or, if less than the entire principal amount
thereof is to be converted, stating the portion thereof to be converted. Such
notice shall also state the name or names (with address and social security or
other taxpayer identification number) in which said certificate or certificates
are to be issued. Such conversion shall be deemed to have been made at the time
that such Security or Securities shall have been surrendered for conversion and
such notice shall have been received by the Issuer or the Trustee, the rights of
the holder of such Security or Securities as a Securityholder shall cease at
such time, the person or persons entitled to receive the shares of Capital Stock
upon conversion of such Security or Securities shall be treated for all purposes
as having become the record holder or holders of such shares of Capital Stock at
such time and such conversion shall be at the conversion rate in effect at such
time. In the case of any Security of any series which is converted in part only,
upon such conversion, the Issuer shall execute and the Trustee shall
authenticate and deliver to the holder thereof, as requested by such holder, a
new Security or Securities of such series of authorized denominations in
aggregate principal amount equal to the unconverted portion of such Security.

                                       72
<PAGE>

     If the last day on which a Security may be converted is not a Business Day
in a place where a conversion agent is located, the Security may be surrendered
to that conversion agent on the next succeeding day that is a Business Day.

     The Issuer will not be required to deliver certificates for shares of
Capital Stock upon conversion while its stock transfer books are closed for a
meeting of shareholders or for the payment of dividends or for any other
purpose, but certificates for shares of Capital Stock shall be delivered as soon
as the stock transfer books shall again be opened.

     SECTION 13.04. No Payment or Adjustment for Interest or Dividends. Unless
otherwise specified as contemplated by Section 2.03 for Securities of such
series, Securities surrendered for conversion during the period from the close
of business on any regular record date (or special record date for payment of
defaulted interest) next preceding any interest payment date to the opening of
business on such interest payment date (except Securities called for redemption
on a redemption date within such period) when surrendered for conversion must be
accompanied by payment of an amount equal to the interest thereon which the
registered holder is to receive on such interest payment date. Payment of
interest shall be made, as of such interest payment date or such date, as the
case may be, to the holder of record of the Securities as of such regular, or
special record date, as applicable. Except where Securities surrendered for
conversion must be accompanied by payment as described above, no interest on
converted Securities will be payable by the Issuer on any interest payment date
subsequent to the date of conversion. No other payment or adjustment for
interest or dividends is to be made upon conversion. Notwithstanding the
foregoing, upon conversion of any Security with original issue discount, the
fixed number of shares of Capital Stock into which such Security is convertible
delivered by the Issuer to the holder thereof shall be applied, first, to pay
the accrued original issue discount attributable to the period from the date of
issuance to the date of conversion of such Security, and, second, to pay the
balance of the principal amount of such Security.

     SECTION 13.05. Adjustment of Conversion Rate. Unless otherwise specified as
contemplated by Section 2.03 for Securities of such series, the conversion rate
for Securities in effect at any time shall be subject to adjustment as follows:

     (a) In case the Issuer shall (i) declare a dividend or make a distribution
on the class of Capital Stock into which Securities of such series are
convertible in shares of its Capital Stock, (ii) subdivide the outstanding
shares of the class of Capital Stock into which Securities of such series are
convertible into a greater number of shares, (iii) combine the outstanding
shares of the class of Capital Stock into which Securities of such series are
convertible into a smaller number of shares, or (iv) issue by reclassification
of the shares, of the class of Capital Stock

                                       73
<PAGE>

into which Securities of such series are convertible (including any such
reclassification in connection with a consolidation or merger in which the
Issuer is the continuing corporation) any shares, the conversion rate for the
Securities of such series in effect at the time of the record date for such
dividend or distribution, or the effective date of such subdivision, combination
or reclassification, shall be proportionately adjusted so that the holder of any
Security of such series surrendered for conversion after such time shall be
entitled to receive the number and kind of shares which he would have owned or
have been entitled to receive had such Security been converted immediately prior
to such time. Similar adjustments shall be made whenever any event listed above
shall occur.

     (b) In case the Issuer shall fix a record date for the issuance of rights
or warrants to all holders of the class of Capital Stock into which Securities
of such series are convertible entitling them (for a period expiring within 45
days after such record date) to subscribe for or purchase shares of such class
of Capital Stock (or securities convertible into shares of such class of Capital
Stock) at a price per share (or, in the case of a right or warrant to purchase
securities convertible into such class of Capital Stock, having a conversion
price per share, after adding thereto the exercise price, computed on the basis
of the maximum number of shares of such class of Capital Stock issuable upon
conversion of such convertible securities, per share of such class of Capital
Stock, so issuable) less than the current market price per share of such class
of Capital Stock (as defined in subsection (e) below) on the date on which such
issuance was declared or otherwise announced by the Issuer (the "Determination
Date"), the number of shares of such class of Capital Stock into which each
$1,000 principal amount of Securities shall be convertible after such record
date shall be determined by multiplying the number of shares of such class of
Capital Stock into which such principal amount of Securities was convertible
immediately prior to such record date by a fraction, of which the numerator
shall be the number of shares of such class of Capital Stock outstanding on the
Determination Date plus the number of additional shares of such class of Capital
Stock offered for subscription or purchase (or in the case of a right or warrant
to purchase securities convertible into such class of Capital Stock, the
aggregate number of additional shares of such class of Capital Stock into which
the convertible securities so offered are initially convertible), and of which
the denominator shall be the number of shares of such class of Capital Stock
outstanding on the Determination Date plus the number of shares of such class of
Capital Stock obtained by dividing the aggregate offering price of the total
number of shares so offered (or, in the case of a right or warrant to purchase
securities convertible into such class of Capital Stock, the aggregate initial
conversion price of the convertible securities so offered, after adding thereto
the aggregate exercise price of such rights or warrants computed on the basis of
the maximum number of shares of such class of Capital Stock issuable upon
conversion of such convertible securities) by such current market price.

                                       74
<PAGE>

Shares of such class of Capital Stock of the Issuer owned by or held for the
account of the Issuer shall not be deemed outstanding for the purpose of any
such computation. Such adjustment shall be made successively whenever such a
record date is fixed; and to the extent that shares of such class of Capital
Stock are not delivered (or securities convertible into shares of such class of
Capital Stock are not delivered) after the expiration of such rights or warrants
(or, in the case of rights or warrants to purchase securities convertible into
such class of Capital Stock once exercised, the expiration of the conversion
right of such securities) the conversion rate shall be readjusted to the
conversion rate which would then be in effect had the adjustments made upon the
issuance of such rights or warrants (or securities convertible into shares) been
made upon the basis of delivery of only the number of shares actually delivered.
In the event that such rights or warrants are not so issued, the conversion rate
shall again be adjusted to be the conversion rate which would then be in effect
if such record date had not been fixed.

     (c) In case the Issuer shall fix a record date for the making of a
distribution to all holders of the class of Capital Stock into which Securities
of such series are convertible (including any such distribution made in
connection with a consolidation or merger in which the Issuer is the continuing
corporation) of evidences of its indebtedness or assets (excluding any cash
dividends paid from retained earnings and dividends payable in Capital Stock for
which adjustment is made pursuant to subsection (a) above or (d) below) or
subscription rights or warrants (excluding subscription rights or warrants to
purchase the class of Capital Stock into which Securities of such series are
convertible), the number of shares of such class of Capital Stock into which
each $1,000 principal amount of Securities of such series shall be convertible
after such record date shall be determined by multiplying the number of shares
of such class of Capital Stock into which such principal amount of Securities
was convertible immediately prior to such record date by a fraction, of which
the numerator shall be the fair market value of the assets of the Issuer, after
deducting therefrom all liabilities of the Issuer and all preferences (including
accrued but unpaid dividends) in respect of classes of Capital Stock having a
preference with respect to the assets of the Issuer over such class of Capital
Stock (all as determined by the Board of Directors, whose determination shall be
conclusive, and described in a certificate signed by any vice chairmen of the
board, vice president or assistant vice president and treasurer of the Issuer,
filed with the Trustee and each conversion agent) on such record date, and of
which the denominator shall be such fair market value after deducting therefrom
such liabilities and preferences, less the fair market value (as determined by
the Board of Directors, whose determination shall be conclusive, and described
in a statement filed with the Trustee and each conversion agent) of the assets
or evidences of indebtedness, so distributed or of such subscription rights or
warrants applicable, so distributed. Such adjustment shall be made successively
whenever such a record date is fixed; and in the event that such distribution is
not so made,

                                       75
<PAGE>

the conversion rate shall again be adjusted to the conversion rate which would
then be in effect if such record date had not been fixed.

     (d) In case the Issuer shall, by dividend or otherwise, distribute to all
holders of its Capital Stock cash (excluding (x) any quarterly cash dividend on
the Capital Stock to the extent the aggregate cash dividend per share of Capital
Stock in any fiscal quarter does not exceed the greater of (A) the amount per
share of Capital Stock of the next preceding quarterly cash dividend on the
Capital Stock to the extent such preceding quarterly dividend did not require
any adjustment of the conversion rate pursuant to this Section 13.05(d) (as
adjusted to reflect subdivisions or combinations of the Capital Stock), and (B)
3.75% of the current market price of the Capital Stock (determined as provided
in Section 13.05(e)) on the date of declaration of such dividend and (y) any
dividend or distribution in connection with the liquidation, dissolution or
winding up of the Issuer, whether voluntary or involuntary), then, in such case,
unless the Issuer elects to reserve such cash for distribution to the holders of
the Securities upon the conversion of the Securities so that any such holder
converting Securities will receive upon such conversion, in addition to the
shares of Capital Stock to which such holder is entitled, the amount of cash
which such holder would have received if such holder had, immediately prior to
the record date for such distribution of cash, converted its Securities into
Capital Stock, the conversion rate shall be adjusted so that the same shall
equal the rate determined by multiplying the conversion rate in effect
immediately prior to the record date by a fraction of which the denominator
shall be the current market price of the Capital Stock (determined as provided
in Section 13.05(e)) on the record date less the amount of cash so distributed
(and not excluded as provided above) applicable to one share of Capital Stock
and the numerator shall be such current market price of the Capital Stock
(determined as provided in Section 13.05(e)), such adjusted to be effective
immediately prior to the opening of business on the day following the record
date; provided, however, that in the event the portion of the cash so
distributed applicable to one share of Capital Stock is equal to or greater than
the current market price of the Capital Stock (determined as provided in Section
13.05(e)) on the record date, in lieu of the foregoing adjustment, adequate
provision shall be made so that each Securityholder shall have the right to
receive upon conversion the amount of cash such holder would have received had
such holder converted each Security on the record date. If such dividend or
distribution is not so paid or made, the conversion rate shall again be adjusted
to be the conversion rate which would then be in effect if such dividend or
distribution had not been declared.

(e) For the purpose of any computation under subsections (b) and (d) above and
Section 13.06, the current market price per share of the Capital Stock on any
date as of which such price is to be computed shall mean the average of the
Closing Prices for the 30 consecutive Business Days commencing 45 Business Days
before such date.

                                       76
<PAGE>

     (f) No adjustment in the conversion rate shall be required unless such
adjustment would require a cumulative increase or decrease of at least 1% in
such rate; provided, however, that any adjustments which by reason of this
subsection (e) are not required to be made shall be carried forward and taken
into account in any subsequent adjustment, and provided, further, that
adjustments shall be required and made in accordance with the provisions of this
Article 13 (other than this subsection (e)) not later than such time as may be
required in order to preserve the tax-free nature of a distribution for United
States income tax purposes to the holders of Securities or the class of Capital
Stock into which such Securities are convertible. All calculations under this
Article 13 shall be made to the nearest cent or to the nearest one-thousandth of
a share, as the case may be. Anything in this Section 13.05 to the contrary
notwithstanding, the Issuer shall be entitled to make such adjustments in the
conversion rate, in addition to those required by this Section 13.05, as it in
its discretion shall determine to be advisable in order that any stock dividend,
subdivision of shares, distribution of rights to purchase stock or securities,
or distribution of securities convertible into or exchangeable for stock
hereafter made by the Issuer to its shareholders shall not be taxable for United
States income tax purposes.

     (g) Whenever the conversion rate is adjusted, as herein provided, the
Issuer shall promptly file with the Trustee and with the office or agency
maintained by the Issuer for the conversion of Securities of such series
pursuant to Section 3.02, a certificate of a firm of independent public
accountants of recognized national standing selected by the Board of Directors
(who may be the regular accountants employed by the Issuer) setting forth the
conversion rate after such adjustment and setting forth a brief statement of the
facts requiring such adjustment and a computation thereof. Such certificate
shall be conclusive evidence of the correctness of such adjustment. Neither the
Trustee nor any conversion agent shall be under any duty or responsibility with
respect to any such certificate or any facts or computations set forth therein,
except to exhibit said certificate from time to time to any Securityholder of
such series desiring to inspect the same. The Issuer shall promptly cause a
notice setting forth the adjusted conversion rate to be mailed to the holders of
Securities of such series, as their names and addresses appear upon the register
of the Issuer.

     (h) In the event that at any time, as a result of shares of any other class
of Capital Stock becoming issuable in exchange or substitution for or in lieu of
shares of the class of Capital Stock into which such Securities are convertible
or as a result of an adjustment made pursuant to subsection (a) above, the
holder of any Security of such series thereafter surrendered for conversion
shall become entitled to receive any shares of the Issuer other than shares of
the class of Capital Stock into which the Issuer of such series are convertible,
thereafter the number of such other shares so receivable upon conversion of any
Security shall be subject to adjustment from time to time in a manner and on
terms as nearly equivalent as practicable to the provisions with respect to the
class of Capital Stock into which the

                                       77
<PAGE>

Securities of such series are convertible contained in subsections (a) to (f),
inclusive, above, and the provisions of this Article 13 with respect to the
class of Capital Stock into which the Securities of such series are convertible
shall apply on like terms to any such other shares.

     (i) The conversion rate with respect to any Securities with original issue
discount, the terms of which provide for convertibility, shall not be adjusted
during the term of such Original Issue Discount Security for accrued original
issue discount.

     (j) In the event that the Securities of any series are convertible into
more than one class of Capital Stock, the provisions of this Section 13.05 shall
apply separately to events affecting each such class.

     SECTION 13.06. No Fractional Shares to Be Issued. No fractional shares of
Capital Stock shall be issued upon conversions of Securities. If more than one
Security of any series shall be surrendered for conversion at one time by the
same holder, the number of full shares which shall be issuable upon conversion
thereof shall be computed on the basis of the aggregate principal amount of the
Securities of such series (or specified portions thereof to the extent permitted
hereby) so surrendered. Instead of a fraction of a share of Capital Stock which
would otherwise be issuable upon conversion of any Security or Securities (or
specified portions thereof), the Issuer shall pay a cash adjustment in respect
of such fraction of a share in an amount equal to the same fractional interest
of the current market price (as defined in Section 13.05) per share of Capital
Stock on the Business Day next preceding the day of conversion.

     SECTION 13.07. Preservation of Conversion Rights Upon Consolidation,
Merger, Sale or Conveyance. In case of any consolidation of the Issuer with, or
merger of the Issuer into, any other corporation (other than a consolidation or
merger in which the Issuer is the continuing corporation), or in the case of any
sale or transfer of all or substantially all of the assets of the Issuer, the
corporation formed by such consolidation or the corporation into which the
Issuer shall have been merged or the corporation which shall have acquired such
assets, as the case may be, shall execute and deliver to the Trustee, a
supplemental indenture, subject to the provisions of Articles 7 and 8 as they
relate to supplemental indentures, providing that the holder of each Security
then Outstanding of a series which was convertible into Capital Stock shall have
the right thereafter to convert such Security into the kind and amount of shares
of stock and other securities and property, including cash, receivable upon such
consolidation, merger, sale or transfer by a holder of the number of shares of
Capital Stock of the Issuer into which such Securities might have been converted
immediately prior to such consolidation, merger, sale or transfer. Such
supplemental indenture shall conform to the provisions of the Trust Indenture
Act of 1939 as then in effect and shall provide for adjustments which shall be
as nearly equivalent as may be

                                       78
<PAGE>

practicable to the adjustments provided for in this Article 13. Neither the
Trustee nor any conversion agent shall be under any responsibility to determine
the correctness of any provision contained in any such supplemental indenture
relating either to the kind or amount of shares of stock or other securities or
property receivable by Securityholders upon the conversion of their Securities
after any such consolidation, merger, sale or transfer, or to any adjustment to
be made with respect there to and, subject to the provisions of Article 5, may
accept as conclusive evidence of the correctness of any such provisions, and
shall be protected in relying upon, an Opinion of Counsel with respect thereto.
If in the case of any such consolidation, merger, sale or transfer, the stock or
other securities and property receivable by a holder of the Securities includes
stock or other securities and property of a corporation other than the successor
or purchasing corporation, then such supplemental indenture shall also be
executed by such other corporation and shall contain such additional provisions
to protect the interests of the holders of the Securities as the Board of
Directors shall reasonably consider necessary. The above provisions of this
Section 13.07 shall similarly apply to successive consolidations, mergers, sales
or transfers.

     SECTION 13.08. Notice to Security Holders of a Series Prior to Taking
Certain Types of Action. With respect to the Securities of any series, in case:

     (a) the Issuer shall authorize the issuance to all holders of the class of
Capital Stock into which Securities of such series are convertible of rights or
warrants to subscribe for or purchase shares of its Capital Stock or of any
other right;

     (b) the Issuer shall authorize the distribution to all holders of the class
of Capital Stock into which Securities of such series are convertible of
evidences of its indebtedness or assets (except for the exclusions with respect
to certain dividends set forth in Section 13.05(c));

     (c) of any subdivision, combination or reclassification of the class of
Capital Stock into which Securities of such series are convertible or of any
consolidation or merger to which the Issuer is a party and for which approval by
the shareholders of the Issuer is required, or of the sale or transfer of all or
substantially all of the assets of the Issuer; or

     (d) of the voluntary or involuntary dissolution, liquidation or winding up
of the Issuer; then the Issuer shall cause to be filed with the Trustee and at
the office or agency maintained for the purpose of conversion of Securities of
such series pursuant to Section 3.02, and shall cause to be mailed to the
holders of Securities of such series, at their last addresses as they shall
appear upon the register of the Issuer, at least ten days prior to the
applicable record date hereinafter specified, a notice stating (i) the date as
of which the holders of such class of Capital Stock to be entitled to receive
any such rights, warrants or

                                       79
<PAGE>

distribution are to be determined, or (ii) the date on which any such
subdivision, combination, reclassification, consolidation, merger, sale,
transfer, dissolution, liquidation, winding up or other action is expected to
become effective, and the date as of which it is expected that holders of record
of such class of Capital Stock shall be entitled to exchange their Capital Stock
of such class for securities or other property, if any, deliverable upon such
subdivision, combination, reclassification, consolidation, merger, sale,
transfer, dissolution, liquidation, winding up or other action. The failure to
give the notice required by this Section 13.08 or any defect therein shall not
affect the legality or validity of any distribution, right, warrant,
subdivision, combination, reclassification, consolidation, merger, sale,
transfer, dissolution, liquidation, winding up or other action, or the vote upon
any of the foregoing. Such notice shall also be published by and at the expense
of the Issuer not later than the aforesaid filing date at least once in an
Authorized Newspaper.

     SECTION 13.09. Covenant to Reserve Shares for Issuance on Conversion of
Securities. The Issuer covenants that at all times it will reserve and keep
available out of each class of its authorized Capital Stock, free from
preemptive rights, solely for the purpose of issue upon conversion of Securities
of any series as herein provided, such number of shares of Capital Stock of such
class as shall then be issuable upon the conversion of all Outstanding
Securities of such series. The Issuer covenants that an shares of Capital Stock
which shall be so issuable shall, when issued or delivered, be duly and validly
issued shares of the class of authorized Capital Stock into which Securities of
such series are convertible, and shall be fully paid and nonassessable, free of
all liens and charges and not subject to preemptive rights and that, upon
conversion, the appropriate capital stock accounts of the Issuer will be duly
credited.

     SECTION 13.10. Compliance with Governmental Requirements. The Issuer
covenants that if any shares of Capital Stock required to be reserved for
purposes of conversion of Securities hereunder require registration or listing
with or approval of any governmental authority under any Federal or State law,
pursuant to the Securities Act of 1933, as amended, or the Securities Exchange
Act of 1934, as amended, or any national or regional securities exchange on
which such Capital Stock is listed at the time of delivery of any shares of such
Capital Stock, before such shares may be issued upon conversion, the Issuer will
use its best efforts to cause such shares to be duly registered, listed or
approved, as the case may be.

     SECTION 13.11. Payment of Taxes Upon Certificates for Shares Issued Upon
Conversion. The issuance of certificates for shares of Capital Stock upon the
conversion of Securities shall be made without charge to the converting
Securityholders for any tax (including, without limitation, all documentary and
stamp taxes) in respect of the issuance and delivery of such certificates, and
such certificates shall be issued in the respective names of, or in such names
as may be

                                       80
<PAGE>

directed by, the holders of the Securities converted; provided, however, that
the Issuer shall not be required to pay any tax which may be payable in respect
of any transfer involved in the issuance and delivery of any such certificate in
a name other than that of the holder of the Security converted, and the Issuer
shall not be required to issue or deliver such certificates unless or until the
person or persons requesting the issuance thereof shall have paid to the Issuer
the amount of such tax or shall have established to the satisfaction of the
Issuer that such tax has been paid.

     SECTION 13.12. Trustee's Duties with Respect to Conversion Provisions. The
Trustee and any conversion agent shall not at any time be under any duty or
responsibility to any Securityholder to determine whether any facts exist which
may require any adjustment of the conversion rate or conversion price, or with
respect to the nature or extent of any such adjustment when made, or with
respect to the method employed, or herein or in any supplemental indenture
provided to be employed, in making the same. Neither the Trustee nor any
conversion agent shall be accountable with respect to the registration under
securities laws, listing, validity or value (or the kind or amount) of any
shares of Capital Stock, or of any other securities or property, which may at
any time be issued or delivered upon the conversion of any Security; and neither
the Trustee nor any conversion agent makes any representation with respect
thereto. Neither the Trustee nor any conversion agent shall be responsible for
any failure of the Issuer to make any cash payment or to issue, transfer or
deliver any shares of stock or stock certificates or other securities or
property upon the surrender of any Security for the purpose of conversion; and
the Trustee, subject to the provisions of Article 5, and any conversion agent
shall not be responsible for any failure of the Issuer to comply with any of the
covenants of the Issuer contained in this Article 13.

                                   Article 14
                                   GUARANTEES

     Section 14.01. The Cable Guarantees. Subject to the provisions of this
Article, each Cable Guarantor hereby irrevocably, fully and unconditionally
guarantees, jointly and severally, on an unsecured subordinated basis, the full
and punctual payment (whether at maturity, upon redemption, or otherwise) of the
Principal of and interest on, and all other amounts payable under, each
Security, and the full and punctual payment of all other amounts payable by the
Issuer under the Indenture. Upon failure by the Issuer to pay punctually any
such amount, each Cable Guarantor shall forthwith on demand pay the amount not
so paid at the place and in the manner specified in the Indenture. The
obligations of each Cable Guarantor under its Cable Guarantee are junior and
subordinated in right of payment to the Senior Indebtedness of such Cable
Guarantor in the same

                                       81
<PAGE>

manner and to the same extent as the Securities are subordinated to the Senior
Indebtedness of the Issuer.

     Section 14.02. Guarantee Unconditional. The obligations of each Cable
Guarantor hereunder are unconditional and absolute and, without limiting the
generality of the foregoing, will not be released, discharged or otherwise
affected by

     (a) any extension, renewal, settlement, compromise, waiver or release in
respect of any obligation of the Issuer under the Indenture or any Security, by
operation of law or otherwise;

     (b) any modification or amendment of or supplement to the Indenture or any
Security;

     (c) any change in the corporate existence, structure or ownership of the
Issuer, or any insolvency, bankruptcy, reorganization or other similar
proceeding affecting the Issuer or its assets or any resulting release or
discharge of any obligation of the Issuer contained in the Indenture or any
Security;

     (d) the existence of any claim, set-off or other rights which any Cable
Guarantor may have at any time against the Issuer, the Trustee, any other Cable
Guarantor or any other Person, whether in connection with the Indenture or an
unrelated transactions, provided that nothing herein prevents the assertion of
any such claim by separate suit or compulsory counterclaim;

     (e) any invalidity, irregularity or unenforceability relating to or against
the Issuer for any reason of the Indenture or any Security, or any provision of
applicable law or regulation purporting to prohibit the payment by the Issuer of
the principal of or interest on any Security or any other amount payable by the
Issuer under the Indenture; or

     (f) any other act or omission to act or delay of any kind by the Issuer,
the Trustee or any other Person or any other circumstance whatsoever which
might, but for the provisions of this paragraph, constitute a legal or equitable
discharge of or defense to such Cable Guarantor's obligations hereunder.

     Section 14.03. Discharge; Reinstatement. Each Cable Guarantor's obligations
hereunder will remain in full force and effect until the Principal of and
interest on the Securities of each series and all other amounts payable by the
Issuer under the Indenture have been paid in full. If at any time any payment of
the Principal of or interest on any Security or any other amount payable by the
Issuer under the Indenture is rescinded or must be otherwise restored or
returned upon the insolvency, bankruptcy or reorganization of the Issuer or
otherwise, each

                                       82
<PAGE>

Cable Guarantor's obligations hereunder with respect to such payment will be
reinstated as though such payment had been due but not made at such time.

     Section 14.04. Waiver by the Cable Guarantors. Each Cable Guarantor
irrevocably waives acceptance hereof, presentment, demand, protest and any
notice not provided for herein, as well as any requirement that at any time any
action be taken by any Person against the Company or any other Person.

     Section 14.05. Subrogation and Contribution. Upon making any payment with
respect to any obligation of the Issuer under this Article, the Cable Guarantor
making such payment will be subrogated to the rights of the payee against the
Issuer with respect to such obligation, provided that the Cable Guarantor may
not enforce either any right of subrogation, or any right to receive payment in
the nature of contribution, or otherwise, from any other Cable Guarantor, with
respect to such payment so long as any amount payable by the Issuer hereunder or
under the Securities remains unpaid.

     Section 14.06. Stay of Acceleration. If acceleration of the time for
payment of any amount payable by the Issuer under the Indenture or the
Securities is stayed upon the insolvency, bankruptcy or reorganization of the
Issuer, all such amounts otherwise subject to acceleration under the terms of
the Indenture are nonetheless payable by the Cable Guarantors hereunder
forthwith on demand by the Trustee or the Holders.

     Section 14.07. Limitation on Amount of Cable Guarantee. Notwithstanding
anything to the contrary in this Article, each Cable Guarantor, and by its
acceptance of Securities, each Holder, hereby confirms that it is the intention
of all such parties that the Cable Guarantee of such Cable Guarantor not
constitute a fraudulent conveyance under applicable fraudulent conveyance
provisions of the United States Bankruptcy Code or any comparable provision of
other U.S. and non-U.S. law. To effectuate that intention, the Trustee, the
Holders and the Cable Guarantors hereby irrevocably agree that the obligations
of each Cable Guarantor under its Cable Guarantee are limited to the maximum
amount that would not render the Cable Guarantor's obligations subject to
avoidance under applicable fraudulent conveyance provisions of the United States
Bankruptcy Code or any comparable provision of other U.S. and non-U.S. law.

     Section 14.08. Execution and Delivery of Cable Guarantee. The execution by
each Cable Guarantor of the Indenture evidences the Cable Guarantee of such
Cable Guarantor, whether or not the person signing as an officer of the Cable
Guarantor still holds that office at the time of authentication of any Security.
The delivery of any Security by the Trustee after authentication constitutes due
delivery of the Cable Guarantee set forth in the Indenture on behalf of each
Cable Guarantor.

     Section 14.09. Release of Cable Guarantee. This Cable Guarantee of a Cable
Guarantor will terminate upon

     (a) A sale or other disposition (including by way of consolidation or
merger) of the Cable Guarantor or the sale or disposition of all or
substantially all the assets of the Cable Guarantor (in each case other than to
the Issuer or a Cable Guarantor or a Person who, prior to such sale or other
disposition, is an affiliate of the Issuer or a Cable Guarantor); or

     (b) Defeasance or discharge of the Securities, as provided in Article 9.

     Upon delivery by the Issuer to the Trustee of an Officers' Certificate and
an Opinion of Counsel to the foregoing effect, the Trustee will execute any
documents reasonably required in order to evidence the release of the Cable
Guarantor from its obligations under its Cable Guarantee.
