                                 [Back of Note]
                   6% Convertible Subordinated Notes due 2006

                  Unless this certificate is presented by the Holder, or an
authorized representative of the Holder, to the issuer or its agent for
registration of transfer, exchange or payment, and any certificate issued is
registered in the name of the Holder or such other name as may be requested by
an authorized representative of the Holder, ANY TRANSFER, PLEDGE OR OTHER USE
HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL inasmuch as the
registered owner hereof, Highland 2000, L.P., has an interest herein.

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

                  1. INTEREST. Adelphia Communications Corporation, a Delaware
corporation (the "Company"), promises to pay interest on the principal amount of
this Note at 6% per annum from January 23, 2001 until February 15, 2006. The
Company shall pay interest, semi-annually in arrears on February 15 and August
15 of each year, or if any such day is not a Business Day, on the next
succeeding Business Day (each an "Interest Payment Date"). Interest on this Note
will accrue from January 23, 2001. The Company shall pay interest (including
post-petition interest in any proceeding under any Bankruptcy Law) on overdue
principal from time to time on demand at a rate equal to the per annum rate on
this Note then in effect; it shall pay interest (including post-petition
interest in any proceeding under any Bankruptcy Law) on overdue installments of
interest (without regard to any applicable grace periods) from time to time on
demand at the same rate to the extent lawful. Interest will be computed on the
basis of a 360-day year of twelve 30-day months.

                  2. METHOD OF PAYMENT. The Company shall make all payments of
principal and interest by mailing a check to the Holder's registered address;
provided that if the Holder has given wire transfer instructions to the Company
at least ten business days prior to the applicable payment date, payment will be
required to be made by wire transfer of immediately available funds to the
account(s) specified by the Holder.

                  3. PAYING  AGENT,  CONVERSION  AGENT AND SECURITY  REGISTRAR.
Initially, the Company will act as Paying Agent, Conversion Agent and Security
Registrar. This Note may be presented for registration of transfer and exchange
at the offices of the Security Registrar. The Company may change any Paying
Agent, Conversion Agent or Security Registrar without notice to the Holder. Any
of the Company's Subsidiaries may act in any such capacity.

                  4. INDENTURE. The terms of this Note include, to the extent
relevant and appropriate (to the extent necessary, as mutually determined by the
Holder and the Company), those stated in an Indenture dated as of January 23,
2001 between the Company and the Trustee (the "Base Indenture") and as
supplemented by a form Third Supplemental Indenture (the "Supplemental
Indenture" and, together with the Base Indenture, the "Indenture"), each of
which is attached hereto; provided that to the extent relevant and appropriate
(to the extent necessary, as mutually determined by the Holder and the Company),
any references in the Indenture to the Trustee shall be deemed to be references
to the Holder, and any terms in the Indenture relating to or in connection with
the obligations or duties of the Trustee shall be irrelevant and shall not be
applicable; provided, further that to the extent any terms in this Note conflict
with terms in the Indenture, the terms in this Note shall supersede the terms in
the Indenture. The intent of the Company and the Holder is that the Holder of
this Note have all of the rights and benefits as though it held this Note under
the Indenture (i.e., as though this Note was issued under the Indenture)
including without limitation the covenants contained in Article 10 of the
Indenture and the events of default and remedies contained in Article 5 of the
Indenture, notwithstanding the fact that there is no Trustee or executed
Indenture.

                  5.       OPTIONAL REDEMPTION.

                  At any time on or after February 16, 2004, the Company may
redeem any portion of this Note, in whole or in part, on at least 30 days, but
no more than 60 days' notice at the following prices (expressed as a percentage
of the principal amount), together with accrued and unpaid interest to, but
excluding, the redemption date:


            Redemption Period Redemption Price February 16, 2004 through
February 14, 2005 102.40% February 15, 2005 through February 14, 2006 101.20%
and 100.00% of the principal amount on February 15, 2006.

                  In the event a portion of this Note is selected for redemption
and this Note is converted in part after such selection, the converted portion
of this Note shall be deemed (so far as may be) to be the portion to be selected
for redemption. The Company may not give notice of any redemption if the Company
has defaulted in payment of interest and the default is continuing.

                  6. NOTICE OF REDEMPTION.

                  Notice of redemption will be mailed at least 30 days but not
more than 60 days before the redemption date to the Holder at the Holder's
address of record. This Note may be redeemed in part but only in integral
multiples of $1,000. On and after the redemption date, interest ceases to accrue
on this Note or portion of it called for redemption.

                  If this Note is redeemed subsequent to a Record Date with
respect to any Interest Payment Date specified above and on or prior to such
Interest Payment Date, then any accrued interest will be paid to the Person in
whose name this Note is registered at the close of business on such Record Date.

                  7. MANDATORY  REDEMPTION.  Except as set forth in paragraph 8
below, the Company shall not be required to make mandatory redemption payments
with respect to this Note. There are no sinking fund payments with respect to
this Note.

                  8. REPURCHASE AT OPTION OF HOLDER. Within 10 days of the
occurrence of a Fundamental Change the Company shall notify the Holder in
writing of such occurrence and shall make an offer to purchase (the "Fundamental
Change Offer") all or any part of this Note at a purchase price equal to 100% of
the principal amount thereof plus any accrued and unpaid interest thereon to the
purchase date, which shall be a Business Day no later than 30 Business Days
after the date of the notice of the Fundamental Change (the "Fundamental Change
Payment Date"). Such right to require the repurchase of this Note shall not
continue after discharge of the Company from its obligations with respect to
this Note. The Board of Directors of the Company may not waive this provision.

                  9. SUBORDINATION.  The payment of the  principal  of, interest
on or any other amounts due on this Note is subordinated in right of payment to
all existing and future Senior Debt of the Company, as described in the
Indenture. The Holder, by accepting this Note, agrees to such subordination.

                  10. CONVERSION. The Holder has the right, exercisable at any
time after the original issuance of this Note and before the close of business
(New York time) on the Business Day immediately preceding the date of this
Note's maturity, to convert the principal amount thereof (or any portion thereof
that is an integral multiple of $1,000) into shares of Class A Common Stock (or
Class B Common Stock if and only if this Note is held by a member or affiliate
of the Rigas Family), at the initial Conversion Price of $55.49 per share,
subject to adjustment under certain circumstances as set forth in the Indenture,
except that if a Note is called for redemption, the conversion right will
terminate at the close of business on the Business Day immediately preceding the
date fixed for redemption (unless the Company shall default in making the
redemption payment when it becomes due, in which case the conversion right shall
terminate on the date such default is cured).

                  To convert this Note, the Holder must (1) complete and sign a
conversion notice for Class A Common Stock substantially in the form set forth
below, or if the Holder is a member or affiliate of the Rigas Family complete
and sign a conversion notice for Class B Common Stock substantially in the form
set forth below, (2) surrender this Note to a Conversion Agent, (3) furnish
appropriate endorsements or transfer documents if required by the Registrar or
Conversion Agent and (4) pay any transfer or similar tax, if required. No
payment or other adjustment for accrued interest or dividends on any Class A
Common Stock (or Class B Common Stock if this Note is held by a member or
affiliate of the Rigas Family), issued upon conversion of this Notes shall be
made by the Company. If this Note is converted during any period after any
Record Date for the payment of an installment of interest but before the next
Interest Payment Date, interest for this Note will be paid on the next Interest
Payment Date, notwithstanding such conversion, to the Holder. If this Note is
delivered to the Company for conversion after any Record Date but before the
next Interest Payment Date, this Note must, except as described in the next
sentence, be accompanied by a payment equal to the interest payable on such
Interest Payment Date on the principal amount of the portion of this Note being
converted. The payment to the Company described in the preceding sentence shall
not be required if, during that period between a Record Date and the next
Interest Payment Date, a conversion occurs on or after the date that the Company
has issued a redemption notice and prior to the date of redemption stated in
such notice. No fractional shares will be issued upon conversion, but a cash
adjustment will be made for any fractional shares.

                  If the Holder has delivered an "Option of Holder to Elect
Purchase" form appearing below exercising the option of the Holder to require
the Company to purchase this Note, this Note may be converted only if the notice
of exercise is withdrawn as provided above and in accordance with the terms of
the Indenture. The above description of conversion of this Note is qualified by
reference to, and is subject in its entirety by, the more complete description
thereof contained in the Indenture, subject, however, to the provisions of
Section 4 of this Note.

                  11. FORM, TRANSFER, EXCHANGE.  This  Note  is in  registered
form without coupons. The transfer of this Note may be registered and this Note
may be exchanged substantially as provided in the Indenture.

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

                  13. AMENDMENT, SUPPLEMENT AND WAIVER.  This Note may be
amended or supplemented with the written consent of the Holder, and any existing
default or compliance with any provision of the Indenture with respect to this
Note may be waived with the consent of the Holder.

                  14. DEFAULTS AND REMEDIES. An Event of Default with respect to
this Note occurs if: (i) the Company defaults in the payment when due of any
interest on this Note and such default continues for a period of 30 days; (ii)
the Company defaults in the payment of the principal of this Note at its
maturity; (iii) the Company fails to observe or perform any other covenant,
representation, warranty or other agreement in the Indenture or this Note for 60
days after written notice to the Company by the Holder; (iv) the Company fails
to pay when due principal, interest or premium aggregating $10,000,000 or more
with respect to any Indebtedness of the Company or any Restricted Subsidiary, or
the acceleration of any such Indebtedness which default shall not be cured or
waived, or such acceleration shall not be rescinded or annulled, within 10 days
after written notice; (v) a final judgment or final judgments for the payment of
money are entered by a court or courts of competent jurisdiction against the
Company or any of its Restricted Subsidiaries and such judgment or judgments
remain undischarged for a period (during which execution shall not be
effectively stayed) of 60 days, provided that the aggregate of all such
judgments exceeds $10,000,000; or (vi) the Company or any Restricted Subsidiary
with liabilities of greater than $10,000,000 under GAAP as of the date of the
event described in this clause, pursuant to or within the meaning of Bankruptcy
Law: (a) commences a voluntary case, (b) consents to the entry of an order for
relief against it in an involuntary case, (c) consents to the appointment of a
Custodian of it or for all or substantially all of its property, or (d) makes a
general assignment for the benefit of its creditors, (vii) a court of competent
jurisdiction enters an order or decree under any Bankruptcy Law that: (a) is for
relief against the Company, or any Restricted Subsidiary with liabilities of
greater than $10,000,000 under GAAP as of the effective date of such order or
decree in an involuntary case, (b) appoints a custodian of the Company, or any
Restricted Subsidiary of Restricted Subsidiary with liabilities of greater than

Company, or any Restricted Subsidiary with liabilities greater than $10,000,000
under GAAP as of the effective date of such order or decree; and the order or
decree remains unstayed and in effect for 60 consecutive days. If any Event of
Default occurs and is continuing, the Holder of this Note may declare it to be
due and payable immediately. Notwithstanding the foregoing, in the case an Event
of Default specified in clauses (6) or (7) of Section 5.1 of the Indenture
occurs with respect to the Company, or a Restricted Subsidiary with liabilities
of greater than $10,000,000 under GAAP as of the effective date of such order or
decree, this Note will become due and payable without further action or notice.
The Holder may waive any existing Default or Event of Default and its
consequences under the Indenture, except a continuing Default or Event of
Default in the payment of the principal of or interest on this Note (provided,
however, that the Holder may rescind an acceleration and its consequence,
including any related payment default) or a default with respect to any covenant
or provision which cannot be modified or amended without the consent of the
Holder.

                  15. NO RECOURSE AGAINST OTHERS. A director, officer, employee,
incorporator or stockholder of the Company, as such, shall not have any
liability for any obligations of the Company under this Note or for any claim
based on, in respect of, or by reason of, such obligations or its creation. The
Holder by accepting this Note waives and releases all such liability including
any rights against any general partner of the Company in its capacity as general
partner. The waiver and release are part of the consideration for the issuance
of this Note.

                  16. ABBREVIATIONS. Customary abbreviations may be used in the
name of a Holder or an assignee, such as: TEN COM (= tenants in common), TEN ENT

that the aggregate amount of outstanding Notes represented thereby may from time
to time be reduced or increased, as appropriate, to reflect exchanges and
redemptions. Any endorsement of the Global Notes to reflect the amount of any
increase or decrease in the amount of outstanding Notes represented thereby
shall be made by the Trustee or the Note Custodian (as hereinafter defined), at
the direction of the Trustee, in accordance with instructions given by the
Holder thereof as required by Section 2.6 hereof.

                  Except as set forth in Section 2.6 hereof, the Global Notes
may be transferred, in whole and not in part, only to another nominee of the
U.S. Depository or to a successor of the U.S. Depository or its nominee.

                  (b) Book-Entry  Provisions.  This  Section  2.1(b) shall apply
only to the Global Notes deposited with or on behalf of the U.S. Depository.

                  The Company shall execute and the Trustee shall, in accordance
with this Section 2.1(b), authenticate and deliver the Global Notes that (i)
shall be registered in the name of the U.S. Depository or the nominee of the
U.S. Depository and (ii) shall be delivered by the Trustee to the U.S.
Depository or pursuant to the U.S. Depository's instructions or held by the Note
Custodian.

                  Agent Members shall have no rights either under this Indenture
with respect to any Global Notes held on their behalf by the U.S. Depository or
by the Note Custodian or under such Global Notes, and the U.S. Depository may be
treated by the Company, the Trustee and any agent of the Company or the Trustee
as the absolute owner of such Global Notes for all purposes whatsoever.

                  (c) Definitive Notes. Notes issued in certificated form shall
be substantially in the form of Exhibit A attached hereto (but without including
the text referred to in Section 2.7 of the Indenture). Except as provided in
Section 2.6, owners of beneficial interests in the Global Notes will not be
entitled to receive physical delivery of certificated Securities.

S 2.2.   Execution and Authentication.

                  The Trustee shall, upon a written order of the Company signed
by an Officer, authenticate up to $167,376,000 aggregate principal amount of
Notes. The aggregate principal amount of Notes outstanding at any time may not
exceed such amounts except as provided in Section 3.6 of the Indenture.

S 2.3.   Conversion.

                  (a)      Conversion Privilege.

                  A Holder of a Note may convert it into fully paid and
nonassessable shares of Class A Common Stock at any time after the date of
original issuance of the Note and before the close of business on the Business
Day immediately preceding the maturity date at the Conversion Price then in
effect, except that, with respect to any Note called for redemption, such
conversion right shall terminate at the close of business on the Business Day
immediately preceding the redemption date (unless the Company shall default in
making the redemption payment when it becomes due, in which case the conversion
right shall terminate on the date such default is cured) , except that if the
beneficial owner of such Note is a member of or directly or indirectly
controlled by the Rigas Family (a "Rigas Holder"), such Note shall be
convertible into fully paid and nonassessable shares of Class B Common Stock
rather than Class A Common Stock. The number of shares of Class A Common Stock
(or Class B Common Stock in the case of a Rigas Holder) issuable upon conversion
of a Note is determined by dividing the principal amount of such Note by the
conversion price in effect on the Conversion Date (the "Conversion Price").

                  The initial Conversion Price is stated in Section 10 of the
Notes and is subject to adjustment as provided in this Section 2.3.

                  A Holder may convert a portion of a Note equal to any integral
multiple of $1,000. Provisions of this Supplemental Indenture that apply to
conversion of all of a Note also apply to conversion of a portion of it.

                  (b)      Conversion Procedure.

                  To convert a Note, a Holder must satisfy the requirements in
Section 10 of the Notes. The date on which the Holder satisfies all of those
requirements is the conversion date (the "Conversion Date"). As soon as
practicable after the Conversion Date, the Company shall deliver to the Holder
through the Conversion Agent a certificate for the number of whole shares of
Class A Common Stock (or of Class B Common Stock in the case of a Rigas Holder)
issuable upon the conversion and a check for any fractional share determined
pursuant to Section 2.3(c) hereof. The Person in whose name the certificate is
registered shall become the stockholder of record on the Conversion Date and, as
of such date, such Person's rights as a Holder shall cease; provided, however,
that no surrender of a Note on any date when the stock transfer books of the
Company shall be closed shall be effective to constitute the Person entitled to
receive the shares of Class A Common Stock (or Class B Common Stock in the case
of a Rigas Holder) upon such conversion as the stockholder of record of such
shares of Class A Common Stock (or Class B Common Stock in the case of a Rigas
Holder) on such date, but such surrender shall be effective to constitute the
Person entitled to receive such shares of Class A Common Stock (or Class B
Common Stock in the case of a Rigas Holder) as the stockholder of record thereof
for all purposes at the close of business on the next succeeding day on which
such stock transfer books are open; provided further, however, that such
conversion shall be at the Conversion Price in effect on the date that such Note
shall have been surrendered for conversion, as if the stock transfer books of
the Company had not been closed; and provided further, however, that in no event
shall any certificate for Class B Common Stock be issued in the name of any
Person other than a Rigas Holder.

                  No payment or other adjustment for accrued interest on the
Notes or dividends on any Class A Common Stock (or Class B Common Stock in the
case of a Rigas Holder) issued upon conversion of the Notes will be made. If any
Notes are converted during any period after any Record Date for the payment of
an installment of interest but before the next Interest Payment Date, interest
for such notes will be paid on the next Interest Payment Date, notwithstanding
such conversion, to the Holders of such Notes. Any Notes that are, however,
delivered to the Company for conversion after any Record Date but before the
next Interest Payment Date must, except as described in the next sentence, be
accompanied by a payment equal to the interest payable on such Interest Payment
Date on the principal amount of convertible notes being converted. The payment
to the Company described in the preceding sentence shall not be required if,
during that period between a Record Date and the next Interest Payment Date, a
conversion occurs on or after the date that the Company has issued a redemption
notice and prior to the date of redemption stated in such notice. No fractional
shares will be issued upon conversion, but a cash adjustment will be made for
any fractional shares.

                  If a Holder converts more than one Note at the same time, the
number of whole shares of Class A Common Stock (or Class B Common Stock in the
case of a Rigas Holder) issuable upon the conversion shall be based on the total
principal amount of Notes converted.

                  Upon surrender of a Note that is converted in part, the
Trustee shall authenticate for the Holder a new Note equal in principal amount
to the unconverted portion of the Note surrendered.

                  (c)      Fractional Shares.

                  The Company shall not issue fractional shares of Class A
Common Stock or Class B Common Stock upon conversion of a Note. In lieu thereof,
the Company will pay an amount in cash based upon the Daily Market Price of the
Class A Common Stock on the trading day prior to the date of conversion.

                  (d)      Taxes on Conversion.

                  The issuance of certificates for shares of Class A Common
Stock or Class B Common Stock, as the case may be, upon the conversion of any
Note shall be made without charge to the converting Holder or converting Rigas
Holder for such certificates or for any tax in respect of the issuance of such
certificates, and such certificates shall be issued in the respective names of,
or in such names as may be directed by, the Holder or Holders of the converted
Note; provided, however, that in the event that certificates for shares of Class
A Common Stock are to be issued in a name other than the name of the Holder of
the Note converted, such Note, when surrendered for conversion, shall be
accompanied by an instrument of transfer, in form satisfactory to the Company,
duly executed by the registered holder thereof or his duly authorized attorney;
and provided further, however, that the Company 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 certificates in a name other than that of the Holder of the
converted Note, and the Company 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 Company the amount of such tax or shall have
established to the satisfaction of the Company that such tax has been paid or is
not applicable.

                  (e)      Company to Provide Stock.

                  The Company shall at all times reserve and keep available,
free from preemptive rights, out of its authorized but unissued Class A Common
Stock and Class B Common Stock, solely for the purpose of issuance upon
conversion of Notes as herein provided, a sufficient number of shares of Class A
Common Stock and Class B Common Stock to permit the conversion of all
outstanding Notes for shares of Class A Common Stock or Class B Common Stock, as
the case may be. All shares of Class A Common Stock or Class B Common Stock
which may be issued upon conversion of the Notes, and all shares of Class A
Common Stock which may be issued upon conversion of the Class B Common Stock,
shall be duly authorized, validly issued, fully paid and nonassessable when so
issued.

                  (f)      Adjustment of Conversion Price.

                  The Conversion Price shall be subject to adjustment from time
to time as follows:

                           (1) In case the Company shall (1) pay a dividend in
                  shares of Class A Common Stock to holders of Class A Common
                  Stock or pay a dividend in shares of Class B Common Stock to
                  holders of Class B Common Stock, (2) make a distribution in
                  shares of Class A Common Stock to holders of Class A Common
                  Stock or make a distribution in shares of Class B Common Stock
                  to holders of Class B Common Stock, (3) subdivide its
                  outstanding shares of Class A Common Stock into a greater
                  number of shares of Class A Common Stock or subdivide its
                  outstanding shares of Class B Common Stock into a greater
                  number of shares of Class B Common Stock, or (4) combine its
                  outstanding shares of Class A Common Stock into a smaller
                  number of shares of Class A Common Stock or combine its
                  outstanding shares of Class B Common Stock into a smaller
                  number of shares of Class B Common Stock; the Conversion Price
                  in effect immediately prior to such action shall be adjusted
                  so that the Holder of any Note thereafter surrendered for
                  conversion shall be entitled to receive the number of shares
                  of Class A Common Stock (or Class B Common Stock in the case
                  of a Rigas Holder) which he would have owned immediately
                  following such action had such Notes been converted
                  immediately prior thereto. Any adjustment made pursuant to
                  this subsection (1) shall become effective immediately after
                  the Record Date in the case of a dividend or distribution and
                  shall become effective immediately after the effective date in
                  the case of a subdivision or combination.

                           (2) In case the Company shall issue rights or
                  warrants to substantially all holders of Class A Common Stock
                  entitling them (for a period commencing no earlier than the
                  Record Date for the determination of holders of Class A Common
                  Stock entitled to receive such rights or warrants and expiring
                  not more than 45 days after such Record Date) to subscribe for
                  or purchase shares of Class A Common Stock (or securities
                  convertible into Class A Common Stock) at a price per share
                  less than the current market price (as determined pursuant to
                  subsection (6) below) of the Class A Common Stock on such
                  Record Date, the Conversion Price (whether for the Class A
                  Common Stock or the Class B Common Stock) shall be adjusted so
                  that the same shall equal the price determined by multiplying
                  the Conversion Price in effect immediately prior to such
                  Record Date by a fraction of which the numerator shall be the
                  number of shares of Class A Common Stock outstanding on such
                  Record Date, plus the number of shares of Class A Common Stock
                  which the aggregate offering price of the offered shares of
                  Class A Common Stock (or the aggregate conversion price of the
                  convertible securities so offered) would purchase at such
                  current market price, and of which the denominator shall be
                  the number of shares of Class A Common Stock outstanding on
                  such Record Date plus the number of additional shares of Class
                  A Common Stock offered (or into which the convertible
                  securities so offered are convertible). Such adjustments shall
                  become effective immediately after such Record Date.

                           (3) In case the Company shall distribute to all
                  holders of Class A Common Stock shares of capital stock of the
                  Company other than Class A Common Stock, evidences of
                  indebtedness or other assets (other than cash dividends), or
                  shall distribute to substantially all holders of Class A
                  Common Stock rights or warrants to subscribe for securities
                  (other than those referred to in subsection (2) above), then
                  in each such case the Conversion Price (whether for the Class
                  A Common Stock or the Class B Common Stock) shall be adjusted
                  so that the same shall equal the price determined by
                  multiplying the Conversion Price in effect immediately prior
                  to the date of such distribution by a fraction of which the
                  numerator shall be the current market price (determined as
                  provided in subsection (6) below) of the Class A Common Stock
                  on the Record Date mentioned below less the then fair market
                  value (as determined by the Board of Directors, whose
                  determination shall be conclusive evidence of such fair market
                  value and described in a resolution of the Board of Directors)
                  of the portion of the assets so distributed or of such
                  subscription rights or warrants applicable to one share of
                  Class A Common Stock, and of which the denominator shall be
                  such current market price of the Class A Common Stock. Such
                  adjustment shall become effective immediately after the Record
                  Date for the determination of the holders of Class A Common
                  Stock entitled to receive such distribution. Notwithstanding
                  the foregoing, in the event that the Company shall distribute
                  rights or warrants (other than those referred to in subsection
                  (2) above) ("Rights") pro rata to holders of Class A Common
                  Stock or Class B Common Stock, as the case may be, the Company
                  may, in lieu of making any adjustment pursuant to this Section
                  2.3(f), make proper provision so that each Holder of a Note
                  who converts such Note (or any portion thereof) after the
                  Record Date for such distribution and prior to the expiration
                  or redemption of the Rights shall be entitled to receive upon
                  such conversion, in addition to the shares of Class A Common
                  Stock (or Class B Common Stock in the case of a Rigas Holder)
                  issuable upon such conversion (the "Conversion Shares"), a
                  number of Rights to be determined as follows: (i) if such
                  conversion occurs on or prior to the date for the distribution
                  to the holders of Rights of separate certificates evidencing
                  such Rights (the "Distribution Date"), the same number of
                  Rights to which a holder of a number of shares of Class A
                  Common Stock or Class B Common Stock, as the case may be,
                  equal to the number of Conversion Shares is entitled at the
                  time of such conversion in accordance with the terms and
                  provisions of and applicable to the Rights; and (ii) if such
                  conversion occurs after the Distribution Date, the same number
                  of Rights to which a holder of the number of shares of Class A
                  Common Stock or Class B Common Stock, as the case may be, into
                  which the principal amount of the Note so converted was
                  convertible immediately prior to the Distribution Date would
                  have been entitled on the Distribution Date in accordance with
                  the terms and provisions of and applicable to the Rights.

                           (4) In case the Company shall, by dividend or
                  otherwise, at any time distribute to all holders of its Class
                  A Common Stock cash (including any distributions of cash out
                  of current or retained earnings of the Company but excluding
                  any cash that is distributed as part of a distribution
                  requiring a Conversion Price adjustment pursuant to paragraph
                  (3) of this Section 2.3) in an aggregate amount that, together
                  with the sum of (x) the aggregate amount of any other
                  distributions to all holders of its Class A Common Stock made
                  in cash plus (y) all Excess Payments, in each case made within
                  the 12 months preceding the date fixed for determining the
                  stockholders entitled to such distribution (the "Distribution
                  Record Date") and in respect of which no Conversion Price
                  adjustment pursuant to paragraphs (3) or (5) of this Section
                  2.3 or this paragraph (4) has been made, exceeds 10% of the
                  product of the current market price per share (determined as
                  provided in paragraph (6) of this Section 2.3) of the Class A
                  Common Stock on the Distribution Record Date times the number
                  of shares of Class A Common Stock outstanding on the
                  Distribution Record Date (excluding shares held in the
                  treasury of the Company), the Conversion Price (whether for
                  Class A Common Stock or Class B Common Stock) shall be reduced
                  so that the same shall equal the price determined by
                  multiplying such Conversion Price in effect immediately prior
                  to the effectiveness of the Conversion Price reduction
                  contemplated by this paragraph (4) by a fraction of which the
                  numerator shall be the current market price per share
                  (determined as provided in paragraph (6) of this Section 2.3)
                  of the Class A Common Stock on the Distribution Record Date
                  less the amount of such cash and other consideration
                  (including any Excess Payments) so distributed applicable to
                  one share (based on the pro rata portion of the aggregate
                  amount of such cash and other consideration (including any
                  Excess Payments), divided by the shares of Class A Common
                  Stock outstanding on the Distribution Record Date) of Class A
                  Common Stock and the denominator shall be such current market
                  price per share (determined as provided in paragraph (6) of
                  this Section 2.3) of the Class A Common Stock on the
                  Distribution Record Date, such reduction to become effective
                  immediately prior to the opening of business on the day
                  following the Distribution Record Date.

                           (5) In case a tender offer made by the Company or any
                  Subsidiary for all or any portion of the Class A Common Stock
                  shall be consummated, if an Excess Payment is made in respect
                  of such tender offer and the amount of such Excess Payment,
                  together with the sum of (x) the aggregate amount of all
                  Excess Payments plus (y) the aggregate amount of all
                  distributions to all holders of the Class A Common Stock made
                  in cash (specifically including distributions of cash out of
                  retained earnings), in each case made within the 12 months
                  preceding the expiration of such current tender offer, as the
                  case may be (the "Purchase Date"), and as to which no
                  adjustment pursuant to paragraph (3) or paragraph (4) of this
                  Section 2.3 or this paragraph (5) has been made, exceeds 10%
                  of the product of the current market price per share
                  (determined as provided in paragraph (6) of this Section 2.3)
                  of the Class A Common Stock on the Purchase Date times the
                  number of shares of Class A Common Stock outstanding
                  (including any tendered shares but excluding any shares held
                  in the treasury of the Company) on the Purchase Date, the
                  Conversion Price (whether for Class A Common Stock or Class B
                  Common Stock) shall be reduced so that the same shall equal
                  the price determined by multiplying such Conversion Price in
                  effect immediately prior to the effectiveness of the
                  Conversion Price reduction contemplated by this paragraph (5)
                  by a fraction of which the numerator shall be the current
                  market price per share (determined as provided in paragraph
                  (6) of this Section 2.3) of the Class A Common Stock on the
                  Purchase Date less the amount of such Excess Payments and such
                  cash distributions, if any, applicable to one share (based on
                  the pro rata portion of the aggregate amount of such Excess
                  Payments and such cash distributions, divided by the shares of
                  Class A Common Stock outstanding on the Purchase Date) of
                  Class A Common and the denominator shall be such current
                  market price per share (determined as provided in paragraph
                  (6) of this Section 2.3) of the Class A Common Stock on the
                  Purchase Date, such reduction to become effective immediately
                  prior to the opening of business on the day following the
                  Purchase Date.

                           (6) The current market price per share of Class A
                  Common Stock on any date shall be deemed to be the average of
                  the Daily Market Prices for the shorter of (i) ten (10)
                  consecutive Business Days ending on the last full trading day
                  on the exchange or market referred to in determining such
                  Daily Market Prices prior to the time of determination or (ii)
                  the period commencing on the date next succeeding the first
                  public announcement of the issuance of such rights or such
                  warrants or such other distribution or such negotiated
                  transaction through such last full trading day on the exchange
                  or market referred to in determining such Daily Market Prices
                  prior to the time of determination.

                           (7) In any case in which this Section 2.3(f) shall
                  require that an adjustment be made immediately following a
                  Record Date, the Company may elect to defer (but only until
                  five (5) Business Days following the filing by the Company
                  with the Trustee of the certificate described in Section
                  2.3(j) hereof) issuing to the Holder of any Note converted
                  after such Record Date the shares of Class A Common Stock (or
                  Class B Common Stock in the case of a Rigas Holder) and other
                  Capital Stock of the Company issuable upon such conversion
                  over and above the shares of Class A Common Stock (or Class B
                  Common Stock in the case of a Rigas Holder) and other Capital
                  Stock of the Company issuable upon such conversion only on the
                  basis of the Conversion Price prior to adjustment; and, in
                  lieu of the shares the issuance of which is so deferred, the
                  Company shall issue or cause its transfer agents to issue due
                  bills or other appropriate evidence of the right to receive
                  such shares.

                           (8) Upon the occurrence of a Change of Control, in
                  which both (a) the Company's stockholders receive
                  consideration per share of Class A Common Stock that is
                  greater than the Conversion Price, without giving effect to
                  the adjustment described below, at the effective time of the
                  Change of Control, and (b) at least 10% of the total
                  consideration paid to the Company's stockholders consists of
                  cash, cash equivalents, securities or other assets (other than
                  publicly traded securities), which are referred to herein as
                  "non-public consideration." In such circumstances, upon
                  conversion of the Notes after the Change of Control, in
                  addition to the Class A Common Stock (or Class B Common Stock
                  in the case of a Rigas Holder) or other securities deliverable
                  upon the conversion of the Notes as described in the other
                  provisions of this Section 2.3, including clauses (1) through
                  (7) of this Section 2.3(f), the Holder will receive a number
                  of publicly traded securities of the acquiror determined
                  through the following calculation:

          PV cashflows X (non-public consideration/total consideration)
          -------------------------------------------------------------
                              Acquiror stock price

                  Where:

                  PV cashflows                       =        the present value
                                                     of the aggregate interest
                                                     payments that would have
                                                     been payable on the Notes
                                                     from the date of conversion
                                                     through February 16, 2004,
                                                     calculated using a discount
                                                     rate equal to the yield to
                                                     maturity of U.S. Treasury
                                                     securities having a
                                                     maturity closest to, but
                                                     not later than, February
                                                     16, 2004,

                  Total consideration                =        the total value of
                                                     the consideration payable
                                                     to the Company's
                                                     stockholders at the
                                                     effective time of the
                                                     Change of Control, with the
                                                     value of any assets or
                                                     securities other than cash
                                                     or a publicly traded
                                                     security being determined
                                                     in good faith by the
                                                     Company's Board of
                                                     Directors based upon an
                                                     opinion as to that value
                                                     obtained from an
                                                     accounting, appraisal or
                                                     investment banking firm of
                                                     international standing,

                  Acquiror stock price               = the price per security of
                                                     the acquiror's publicly
                                                     traded securities delivered
                                                     in connection with the
                                                     Change of Control
                                                     transaction at the
                                                     effective time of the
                                                     Change of Control

                  provided, however, that if the consideration received by the
                  Company's stockholders in respect of the Change of Control
                  consists of at least 75% non-public consideration or if the
                  acquiror's common stock is not publicly traded, then upon
                  conversion of the Notes after the Change of Control, in lieu
                  of issuing additional securities of the acquiror, as set forth
                  above, the Holder will be entitled to receive an additional
                  amount in cash calculated as follows:

                           PV cashflows X (non-public consideration/total
                            consideration)

                  (g)      No Adjustment.

                  No adjustment in the Conversion Price shall be required until
cumulative adjustments amount to 1% or more of the Conversion Price as last
adjusted; provided, however, that any adjustments which by reason of this
Section 2.3(g) are not required to be made shall be carried forward and taken
into account in any subsequent adjustment. All calculations under this Section
2.3 shall be made to the nearest cent or to the nearest one-hundredth of a
share, as the case may be. No adjustment need be made for rights to purchase
Class A Common Stock or Class B Common Stock, as the case may be, pursuant to a
Company plan for reinvestment of dividends or interest. No adjustment need be
made for a change in the par value or no par value of the Class A Common Stock
or Class B Common Stock, as the case may be,.

                  (h)      Other Adjustments.

                           (1) In the event that, as a result of an adjustment
                  made pursuant to Section 2.3(f) hereof, the Holder of any Note
                  thereafter surrendered for conversion shall become entitled to
                  receive any shares of Capital Stock of the Company other than
                  shares of its Class A Common Stock (or Class B Common Stock in
                  the case of a Rigas Holder), thereafter the Conversion Price
                  of such other shares so receivable upon conversion of any Note
                  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 Class A Common Stock and Class B
                  Common Stock contained in this Section 2.3.

                           (2) In the event that shares of Class A Common Stock
                  or Class B Common Stock are not delivered after the expiration
                  of any of the rights or warrants referred to in Section
                  2.3(f)(2) and Section 2.3(f)(3) hereof, the Conversion Price
                  shall be readjusted to the Conversion Price which would
                  otherwise be in effect had the adjustment made upon the
                  issuance of such rights or warrants been made on the basis of
                  delivery of only the number of shares of Class A Common Stock
                  or Class B Common Stock actually delivered.

                  (i)      Adjustments for Tax or Other Purposes.

                  The Company may make such reductions in the Conversion Price,
in addition to those required by Section 2.3(f) hereof, as it determines to be
advisable in order that any stock dividend, subdivision of shares, distribution
or rights to purchase stock or securities or distribution of securities
convertible into or exchangeable for stock made by the Company to its
stockholders will not be taxable to the recipients thereof.

                  The Company may decrease the Conversion Price for any period
of at least 20 days, upon at least 15 days notice, if the Company's Board of
Directors determines that such decrease would be in the Company's best interest.
The Board of Directors' determination in this regard shall be conclusive. The
Company shall give Holders at least 15 days notice of such a decrease in the
Conversion Price. Any decrease, however, shall not be taken into account for
such purposes of determining whether the closing price of the Company's Class A
Common Stock exceeds the Conversion Price by 105% in connection with an event
that would otherwise be a Change of Control.

                  (j)      Notice of Adjustment.

                  Whenever the Conversion Price is adjusted, the Company shall
promptly mail to Holders at the addresses appearing on the Registrar's books a
notice of the adjustment and file with the Trustee an Officers' Certificate
briefly stating the facts requiring the adjustment and the manner of computing
it. The certificate shall be conclusive evidence of the correctness of such
adjustment. Unless and until a Responsible Officer of the Trustee shall receive
written notice of an adjustment of the Conversion Price, the Trustee may assume
without inquiry that the Conversion Price has not been adjusted and that the
last Conversion Price of which it has knowledge remains in effect.

                  (k)      Notice of Certain Transactions.

                  In the event that:

                           (1)      the Company takes any action which would
                  require an adjustment in the Conversion Price;

                           (2)      the Company takes any action that would
                  require a supplemental indenture pursuant to Section 2.3(l);
                  or

                           (3)      there is a dissolution or liquidation of the
                  Company;

                  the Company shall mail to Holders at the addresses appearing
on the Registrar's books and the Trustee a notice stating the proposed record or
effective date, as the case may be, to permit a Holder of a Note to convert such
Note into shares of Class A Common Stock (or Class B Common Stock in the case of
a Rigas Holder), prior to the Record Date for or the effective date of the
transaction in order to receive the rights, warrants, securities or assets which
a holder of shares of Class A Common Stock or Class B Common Stock, as the case
may be, on that date may receive. The Company shall mail the notice at least 15
days before such date; however, failure to mail such notice or any defect
therein shall not affect the validity of any transaction referred to in clause
(1), (2) or (3) of this Section 2.3(k).

                  (l)      Effect of Reclassifications, Consolidations, Mergers
or Sales on Conversion Privilege.

                  If any of the following shall occur, namely: (i) any
reclassification or change of outstanding shares of Class A Common Stock or
Class B Common Stock, as the case may be, issuable upon conversion of Notes
(other than a change in par value, or from par value to no par value, or from no
par value to par value, or as a result of a subdivision or combination), (ii)
any consolidation or merger to which the Company is a party other than a merger
in which the Company is the continuing corporation and which does not result in
any reclassification of, or change (other than a change in name, or par value,
or from par value to no par value, or from no par value to par value or as a
result of a subdivision or combination) in, outstanding shares of Class A Common
Stock and Class B Common Stock or (iii) any sale or conveyance of all or
substantially all of the property or business of the Company as an entirety,
then the Company, or such successor or purchasing corporation, as the case may
be, shall, as a condition precedent to such reclassification, change,
consolidation, merger, sale or conveyance, execute and deliver to the Trustee a
supplemental indenture in form reasonably satisfactory to the Trustee providing
that the Holder of each Note then outstanding shall have the right to convert
such Note into the kind and amount of shares of stock and other securities and
property (including cash) receivable upon such reclassification, change,
consolidation, merger, sale or conveyance by a holder of the number of shares of
Class A Common Stock or Class B Common Stock, as the case may be, deliverable
upon conversion of such Note immediately prior to such reclassification, change,
consolidation, merger, sale or conveyance. Such supplemental indenture shall
provide for adjustments of the Conversion Price which shall be as nearly
equivalent as may be practicable to the adjustments of the Conversion Price
provided for in this Section 2.3. The foregoing, however, shall not in any way
affect the right a Holder of a Note may otherwise have, pursuant to clause (ii)
of the last sentence of subsection (3) of Section 2.3(f) hereof, to receive
Rights upon conversion of a Note. If, in the case of any such consolidation,
merger, sale or conveyance, the stock or other securities and property
(including cash) receivable thereupon by a holder of Class A Common Stock or
Class B Common Stock, as the case may be, includes shares of stock or other
securities and property of a corporation other than the successor or purchasing
corporation, as the case may be, in such consolidation, merger, sale or
conveyance, 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 Notes as the Board of Directors of the Company
shall reasonably consider necessary by reason of the foregoing. The provision of
this Section 2.3(l) shall similarly apply to successive consolidations, mergers,
sales or conveyances.

                  In the event the Company shall execute a supplemental
indenture pursuant to this Section 2.3(l), the Company shall promptly file with
the Trustee an Officers' Certificate briefly stating the reasons therefor, the
kind or amount of shares of stock or securities or property (including cash)
receivable by holders of the Notes upon the conversion of their Notes after any
such reclassification, change, consolidation, merger, sale or conveyance and any
adjustment to be made with respect thereto.

                  (m)      Trustee's Disclaimer.

                  The Trustee has no duty to determine when an adjustment under
this Section 2.3 should be made, how it should be made or what such adjustment
should be, but may accept as conclusive evidence of the correctness of any such
adjustment, and shall be protected in relying upon, the Officers' Certificate
with respect thereto which the Company is obligated to file with the Trustee
pursuant to Section 2.3(j) hereof. The Trustee makes no representation as to the
validity or value of any securities or assets issued upon conversion of Notes,
and the Trustee shall not be responsible for the Company's failure to comply
with any provisions of this Section 2.3.

                  The Trustee shall not be under any responsibility to determine
the correctness of any provisions contained in any supplemental indenture
executed pursuant to Section 2.3(l), but may accept as conclusive evidence of
the correctness thereof, and shall be protected in relying upon, the Officers'
Certificate with respect thereto which the Company is obligated to file with the
Trustee pursuant to Section 2.3(l) hereof.

S 2.4.   Redemption.

                  With respect to the Notes issued under this Supplemental
Indenture, the following Sections supplement Article 11 of the Indenture:

                  S 11.8.  Optional Redemption.

                  The Company may redeem all or any portion of the Notes upon
the terms and at the redemption prices set forth in the Notes. In the event that
the Company redeems all or any portion of the 6% Convertible Subordinated Notes
due 2006 issued pursuant to that certain First Supplemental Indenture dated
January 23, 2001, the Company shall at the same time redeem an equivalent
percentage of the Notes issued under this Supplemental Indenture. Any redemption
pursuant to this Section 11.8 shall be made pursuant to the provisions of
Article 11 hereof.

                  S 11.8.  Mandatory Redemption.

                  The Company shall not be required to make mandatory redemption
payments or sinking fund payments with respect to the Notes.

S 2.5.   U.S. Depository and Paying Agent for Notes.

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

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

S 2.6.   Transfer and Exchange of Notes.

                  (a) Transfer and Exchange of Global Notes. The transfer and
exchange of beneficial interests in the Global Notes shall be effected through

U.S. Depository therefor. Beneficial interests in the Global Notes may be
transferred to Persons who take delivery thereof in the form of a beneficial
interest in the Global Notes.

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

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

                           (y)      to exchange such Definitive Notes for an
                                    equal principal amount of Definitive Notes
                                    of other authorized denominations, the
                                    Security Registrar shall register the
                                    transfer or make the exchange as requested
                                    if its requirements for such transactions
                                    are met; provided, however, that the
                                    Definitive Notes presented or surrendered
                                    for register of transfer or exchange shall
                                    be duly endorsed or accompanied by a written
                                    instruction of transfer in form satisfactory
                                    to the Security Registrar duly executed by
                                    such Holder or by his attorney, duly
                                    authorized in writing.

                  (c)      Intentionally omitted.

                  (d)      Restrictions  on  Transfer  and  Exchange  of Global
Notes. Notwithstanding any other provision of this Indenture (other than the
provisions set forth in subsection (f) of this Section 2.6), the Global Notes
may not be transferred as a whole except by the U.S. Depository to a nominee of
the U.S. Depository or by a nominee of the U.S. Depository to the U.S.
Depository or another nominee of the U.S. Depository or by the U.S. Depository
or any such nominee to a successor U.S. Depository or a nominee of such
successor U.S. Depository.

                  (e)      Intentionally omitted.

                  (f)      Authentication of Definitive Notes in Absence of U.S.
Depository.  If at any time:

                           (i)      the U.S. Depository for the Notes notifies
                                    the Company that the U.S. Depository is
                                    unwilling or unable to continue as U.S.
                                    Depository for the Global Notes and a
                                    successor U.S. Depository for the Global
                                    Notes is not appointed by the Company within
                                    90 days after delivery of such notice; or

                           (ii)     the Company at its sole discretion, notifies
                                    the Trustee in writing that it elects to
                                    cause the issuance of Definitive Notes under
                                    this Indenture,

then the Company shall execute, and the Trustee shall, upon receipt of an
authentication order in accordance with Section 2.2 hereof, authenticate and
deliver, Definitive Notes in an aggregate principal amount equal to the
principal amount of the Global Notes in exchange for such Global Notes.

                  (g)      Intentionally omitted.

                  (h) Cancellation and/or Adjustment of the Global Notes. At
such time as all beneficial interests in the Global Notes have been exchanged
for Definitive Notes, redeemed, repurchased or canceled, the Global Notes shall
be returned to or retained and canceled by the Trustee in accordance with
Section 3.9 of the Indenture. At any time prior to such cancellation, if any
beneficial interest in the Global Notes is exchanged for Definitive Notes,
redeemed, repurchased or canceled, the principal amount of Notes represented by
the Global Notes shall be reduced accordingly and an endorsement shall be made
on the Global Notes, by the Trustee or the Note Custodian, at the direction of
the Trustee, to reflect such reduction.

                  (i)    General Provisions Relating to Transfers and Exchanges.

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

                           (ii)     No service charge shall be made to a Holder
                                    for any registration of transfer or
                                    exchange, but the Company may require
                                    payment of a sum sufficient to cover any
                                    transfer tax or similar governmental charge
                                    payable in connection therewith (other than
                                    any such transfer taxes or similar
                                    governmental charge payable upon exchange or
                                    transfer pursuant to Section 2.6 hereto).

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

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

                           (v)      The Trustee shall authenticate Definitive
                                    Notes and the Global Notes in accordance
                                    with the provisions of Section 2.2 of the
                                    Supplemental Indenture and Section 3.3 of
                                    the Indenture.

S 2.7.   Change of Control Offer.

                  Within 10 days of the occurrence of a Fundamental Change the
Company shall notify the Trustee in writing of such occurrence and shall make an
offer to purchase (the "Fundamental Change Offer") the Notes at a purchase price
equal to 100% of the principal amount thereof plus any accrued and unpaid
interest thereon to the Fundamental Change Payment Date (as hereinafter defined)
(the "Fundamental Change Purchase Price") in accordance with the procedures set
forth in this covenant.

                  Within 10 days of the occurrence of a Fundamental Change the
Company also shall send by first-class mail, postage prepaid, to the Trustee and
to each Holder, at his address appearing in the Security Register, a notice
stating:

                           (1) that the Fundamental Change Offer is being made
                  pursuant to this covenant and that all Notes tendered will be
                  accepted for payment, provided that a Fundamental Change has
                  occurred and otherwise subject to the terms and conditions set
                  forth herein;

                           (2) the Fundamental Change Purchase Price and the
                  purchase date (which shall be a Business Day no earlier than
                  30 days from the date such notice is mailed and no later than
                  30 Business Days after the date of the notice of the
                  corresponding Fundamental Change) (the "Fundamental Change
                  Payment Date");

                           (3) that any Note not tendered will continue to
                  accrue interest;

                           (4) that, unless the Company defaults in the payment
                  of the Fundamental Change Purchase Price, any Notes accepted
                  for payment pursuant to the Fundamental Change Offer shall
                  cease to accrue interest after the Fundamental Change Payment
                  Date;

                           (5) that Holders accepting the offer to have their
                  Notes purchased pursuant to a Fundamental Change Offer will be
                  required to surrender the Notes to the Paying Agent at the
                  address specified in the notice prior to the close of business
                  on the Business Day preceding the Fundamental Change Payment
                  Date;

                           (6) that Holders will be entitled to withdraw their
                  acceptance if the Paying Agent receives, not later than the
                  close of business on the third Business Day preceding the
                  Fundamental Change Payment Date, a telegram, telex, facsimile
                  transmission or letter setting forth the name of the Holder,
                  the principal amount of the Notes delivered for purchase, and
                  a statement that such Holder is withdrawing his election to
                  have such Notes purchased;

                           (7) that Holders whose Notes are being purchased only
                  in part will be issued new Notes equal in principal amount to
                  the unpurchased portion of the Notes surrendered, provided
                  that each Note purchased and each such new Note issued shall
                  be in an original principal amount in denominations of $1,000
                  and integral multiples thereof; and

                           (8) any other procedures that a Holder must follow to
                  accept a Fundamental Change Offer or effect withdrawal of such
                  acceptance.

                  On the Fundamental Change Payment Date, the Company shall (a)
accept for payment Notes or portions thereof tendered pursuant to the
Fundamental Change Offer, (b) deposit with the Paying Agent money sufficient to
pay the purchase price of all Notes or portions thereof so tendered and (c)
deliver or cause to be delivered to the Trustee Notes so accepted together with
an Officers' Certificate stating the Notes or portions thereof tendered to the
Company. The Paying Agent shall promptly mail to each Holder of Notes so
accepted payment in an amount equal to the purchase price for such Notes, and
the Company shall issue and the Trustee shall promptly authenticate and mail to
such Holder a new Note equal in principal amount to any unpurchased portion of
the Notes surrendered; provided that each such new Note shall be issued in an
original principal amount in denominations of $1,000 and integral multiples
thereof.

                  The Company shall not be required to make a Fundamental Change
Offer following a Fundamental Change if a third party makes the Fundamental
Change Offer in the manner, at the times and otherwise in compliance with the
requirements set forth in this Indenture applicable to a Fundamental Change
Offer made by the Company and purchases all of the Notes validly tendered and
not withdrawn under such Fundamental Change Offer.

                  The Company shall also offer to purchase all Notes not
previously called for redemption or repurchase, if at any time, (1) the Rigas
Family or any of its Affiliates purchases, in a transaction or series of
transactions, shares of Class A Common Stock, and solely as a result of such
purchases, the aggregate number of shares of Class A Common Stock held by the
Rigas Family and its Affiliates exceeds 70% of the total number of shares of
Class A Common Stock issued and outstanding at such time and (2) the closing
price per share of the Class A Common Stock for any five (5) trading days within
the period of the ten (10) consecutive trading days immediately after the later
of the last date of such purchase or the public announcement of such purchase is
less than 100% of the Conversion Price of the Notes in effect on each of those
trading days. For purposes of this Indenture such event shall constitute a
Change of Control and the Company shall follow procedures substantially similar
to the procedures for a Fundamental Change Offer as set forth in this Indenture.
The Notes purchased pursuant to this paragraph shall be purchased at a price
equal to 100% of the aggregate principal amount of the Notes to be purchased
together with the interest accrued to, but excluding, the purchase date.

                  For purposes of the foregoing paragraph, a purchase shall not
include any shares of Class A Common Stock acquired by the Rigas Family or its
Affiliates as a result of the exchange or conversion of shares of the Company's
Class B Common Stock, and the calculation of the number of shares of Class A
Common Stock held by the Rigas Family and its Affiliates shall not include
securities exchangeable or convertible into shares of Class A Common Stock.

                  There shall be no purchase of any Notes pursuant to this
covenant if there has occurred (prior to, on or after, as the case may be, the
tender of such Notes pursuant to the Fundamental Change Offer, by the Holders of
such Notes) and is continuing an Event of Default. The Paying Agent will
promptly return to the respective holders thereof any Notes (a) the tender of
which has been withdrawn in compliance with this Indenture or (b) held by it
during the continuance of an Event of Default (other than a default in the
payment of the Change of Control Purchase Price with respect to such Notes).

                  In the event that the Company is required to make (or to
follow procedures substantially similar to) a Fundamental Change Offer, the
Company will comply with all applicable tender offer rules including Rule 14e-1
under the Exchange Act, to the extent applicable.

S 2.8.   Events of Default.

                  With respect to the Notes issued under this Supplemental
Indenture, Section 5.1 of the Indenture is hereby replaced in its entirety as

                  and payable at maturity, upon acceleration or otherwise,

                  Subsidiary, or the acceleration of any such Indebtedness which
                  default shall not be cured or waived, or such acceleration

                  $10,000,000 against the Company or any Restricted Subsidiary
                  and such judgment remains undischarged for a period of 60

                                                     effective date of such
                                                     order or decree, in an
                                                     involuntary case,

                                            (B)      appoints a Custodian of the
                                                     Company, or any Restricted
                                                     Subsidiary with liabilities
                                                     of greater than $10,000,000
                                                     under GAAP as of the
                                                     effective date of such
                                                     order or decree, or for all
                                                     or substantially all of its
                                                     property, or

                                            (C)      orders the liquidation of
                                                     the Company, or any
                                                     Restricted Subsidiary with
                                                     liabilities of greater than
                                                     $10,000,000 under GAAP as
                                                     of the effective date of
                                                     such order or decree, and
                                                     the order or decree remains
                                                     unstayed and in effect for
                                                     60 days.

                  A Default under clauses (3) and (4) is not an Event of Default
until the Trustee notifies the Company, or the Holders of at least 25% in
aggregate principal amount of a series of Notes notifies the Company and the
Trustee, of the Default and the Company does not cure the Default within (a) 60
days after receipt of such notice in the case of a Default under clause (3) and
(b) 10 days after receipt of such notice in the case of a Default under clause
(4). The notice must specify the Default, demand that it be remedied and state
that the notice is a "Notice of Default." If the Holders of at least 25% in
principal amount of a series of outstanding Notes request the Trustee to give
such notice on their behalf, the Trustee shall do so.

S 2.9.   Acceleration.

                  With respect to the Notes issued under this Supplemental
Indenture, Section 5.2 of the Indenture is hereby replaced in its entirety as
follows:

                  If an Event of Default with respect to the Notes (other than
an Event of Default specified in Section 2.8(6) or (7) of this Supplemental
Indenture) occurs and is continuing, the Trustee by notice to the Company, or
the Holders of not less than 25% in aggregate principal amount of the Notes
affected thereby then outstanding may declare to be immediately due and payable,
subject to the provisions of Article 15 of this Indenture, the principal amount
of the Notes then outstanding plus accrued but unpaid interest to the date of
acceleration; provided, however, that after such acceleration but before a
judgment or decree based on such acceleration is obtained by the Trustee, the
Holders of a majority in aggregate principal amount of the outstanding Notes by
written notice to the Trustee and the Company may rescind and annul such
acceleration and its consequences if all existing Events of Default, other than
the nonpayment of accelerated principal or interest, have been cured or waived.
In case an Event of Default specified in Section 2.8(6) or (7) of the
Supplemental Indenture occurs, such amount with respect to all of the Notes
shall be due and payable immediately without any declaration or other act on the
part of the Trustee or the Holders of the Notes.

S 2.10.  Mergers and Consolidations.

                  With respect to the Notes issued under this Supplemental
Indenture, Section 8.1 of the Indenture is replaced in its entirety as follows:

                           The Company may not consolidate with, merge with or
         into, or transfer all or substantially all of its assets (as an
         entirety or substantially as an entirety in one transaction or a series
         of related transactions), to any Person unless: (i) the Company shall
         be the continuing Person, or the Person (if other than the Company)
         formed by such consolidation or into which the Company is merged or to
         which the properties and assets of the Company are transferred shall be
         a corporation organized and existing under the laws of the United
         States or any State thereof or the District of Columbia and shall
         expressly assume, by a supplemental indenture, executed and delivered
         to the Trustee, in form satisfactory to the Trustee, all of the
         obligations of the Company under the Notes and this Indenture, and the
         obligations under this Indenture shall remain in full force and effect;
         and (ii) immediately before and immediately after giving effect to such
         transaction, no Default or Event of Default shall have occurred and be
         continuing.

                           In connection with any consolidation, merger or
         transfer contemplated by this Section 8.1, the Company shall deliver,
         or cause to be delivered, to the Trustee, in form and substance
         reasonably satisfactory to the Trustee, an Officers' Certificate and an
         Opinion of Counsel, each stating that such consolidation, merger or
         transfer and the supplemental indenture in respect thereto comply with
         this Section 8.1 and that all conditions precedent herein provided for
         relating to such transaction or transactions have been complied with.

S 2.11.  Supplemental Indentures.

                  With respect to the Notes issued under this Supplemental
Indenture, the following Section supplements Article 9 of the Indenture:

                  S9.7     Revocation and Effect of Consents.

                           Until an amendment, supplement, waiver or other
         action becomes effective, a consent to it by a Holder of a Note is a
         continuing consent conclusive and binding upon such Holder and every
         subsequent Holder of the same Note or portion thereof, and of any Note
         issued upon the transfer thereof or in exchange therefor or in place
         thereof, even if notation of the consent is not made on any such Note.
         Any such Holder or subsequent Holder, however, may revoke the consent
         as to his Note or portion of a Note, if the Trustee receives the notice
         of revocation before the date the amendment, supplement, waiver or
         other action becomes effective.

                           The Company may, but shall not be obligated to, fix a
         record date for the purpose of determining the Holders entitled to
         consent to any amendment, supplement, or waiver. If a record date is
         fixed, then, notwithstanding the preceding paragraph, those Persons who
         were Holders at such record date (or their duly designated proxies),
         and only such Persons, shall be entitled to consent to such amendment,
         supplement, or waiver or to revoke any consent previously given,
         whether or not such Persons continue to be Holders after such record
         date. No such consent shall be valid or effective for more than 90 days
         after such record date unless the consent of the requisite number of
         Holders has been obtained.

                           After an amendment, supplement, waiver or other
         action becomes effective, it shall bind every Noteholder, unless it
         makes a change described in any of clauses (1) through (4) of Section
         9.2 of the Indenture. In that case the amendment, supplement, waiver or
         other action shall bind each Holder of a Note who has consented to it
         and every subsequent Holder of a Note or portion of a Note that
         evidences the same debt as the consenting Holder's Note.

S 2.12.  Covenants.

       With respect to the Notes issued under this Supplemental Indenture,

                  (1) references in the Indenture to the following sections are
                       modified as follows:

</TABLE>

                  and (2) Article 10 of the Indenture is hereby replaced in its
                   entirety as follows:

                                   ARTICLE 10

                                    COVENANTS

         S 10.1 Payment of Notes.

                           The Company shall pay the principal of and all
         interest on the Notes on the dates and in the manner provided in the
         Notes and this Indenture. An installment of principal or interest shall
         be considered paid on the date it is due if the Trustee or Paying Agent
         holds on that date money designated for and sufficient to pay such
         installment.

                           The Company will pay interest on overdue principal
         (including post-petition interest in a proceeding under any Bankruptcy
         Law) and on overdue interest, to the extent lawful, at the rate borne
         by the Notes.

         S 10.2 SEC Reports.

                           The Company shall file with the Trustee, within 15
         days after it files with the SEC, copies of the annual reports and of
         the other information, documents and reports (or copies of such
         portions of any of the foregoing as the SEC may by rules and
         regulations prescribe), if any, which the Company is required to file
         with the SEC pursuant to Section 13 or 15(d) of the Securities Exchange
         Act of 1934, as amended. The Company shall also comply with the other
         provisions of TIA S 314(a).

         S 10.3   Waiver of Stay, Extension or Usury Laws.

                           The Company covenants (to the extent that it may
         lawfully do so) that it will not at any time insist upon, or plead (as
         a defense or otherwise) or in any manner whatsoever claim or take the
         benefit or advantage of, any stay or extension law or any usury law or
         other law which would prohibit or forgive the Company from paying all
         or any portion of the principal of and/or interest on the Notes as
         contemplated herein, wherever enacted, now or at any time hereafter in
         force, or which may affect the covenants or the performance of this
         Indenture; and (to the extent that it may lawfully do so) the Company
         hereby expressly waives all benefit or advantage of any such law, and
         covenants that it will not hinder, delay or impede the execution of any
         power herein granted to the Trustee, but will suffer and permit the
         execution of every such power as though no such law had been enacted.

         S 10.4 Reports to Holders.

                           The Company will send to the Trustee and to
         Noteholders, within 15 days after the filing thereof with the SEC,
         copies of its annual reports on Form 10-K, its Quarterly Reports on
         Form 10-Q and its Current Reports on Form 8-K; provided, however, that
         notwithstanding any event which results in the Company being relieved
         of its obligation to file information, documents and reports with the
         SEC pursuant to Sections 13 or 15(d) of the Exchange Act, the Company
         shall nevertheless continue, so long as any Note remains outstanding
         and unpaid, to file with the SEC (at such time as it would be required
         to file such reports under the Exchange Act), and to send to the
         Trustee and Noteholders (within 15 days thereafter), quarterly and
         annual reports and information, documents and other reports
         substantially equivalent to those it would have been obligated to file
         if it had remained subject to such sections of the Exchange Act.

         S 10.5   Money for Securities Payments to Be Held in Trust.

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

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

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

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

                                    (ii) give the Trustee notice of any default
                           by the Company (or any other obligor upon the
                           Securities of that series) in the making of any
                           payment of principal (and premium, if any) or
                           interest on the Securities of that series; and

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

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

                           Any money deposited with the Trustee or any Paying
         Agent, or then held by the Company, in trust for the payment of the
         principal of (and premium, if any) or interest on any security of any
         series and remaining unclaimed for two years after such principal (and
         premium, if any) or interest has become due and payable shall be paid
         to the Company on Company Request, or (if then held by the Company)
         shall be discharged from such trust; and the Holder of such security
         shall thereafter, as an unsecured general creditor, look only to the
         Company for payment thereof, unless an abandoned property law
         designates another Person, and all liability of the Trustee or such
         Paying Agent with respect to such trust money, and all liability of the
         Company as trustee thereof, shall thereupon cease; provided, however,
         that the Trustee of such Paying Agent, before being required to make
         any such repayment, may at the expense of the Company cause to be
         published once, in a newspaper published in the English language,
         customarily published on each Business Day and of general circulation
         in New York, New York, notice that such money remains unclaimed and
         that, after a date specified therein, which shall not be less than 30
         days from the date of such publication, any unclaimed balance of such
         money then remaining will be repaid to the Company.

         S 10.6   Notice of Defaults Or Events of Default.

                           In the event that any Default or Event of Default
         shall occur and be continuing, the Company will, within 10 days of the
         occurrence thereof, give written notice of such Default or Event of
         Default to the Trustee.

         S 10.7 Compliance Certificates.

                           The Company shall deliver to the Trustee on or before
         105 days after the end of its fiscal year and on or before 50 days
         after the end of its second fiscal quarter in each year an Officers'
         Certificate stating whether or not the signers know of any Default or
         Event of Default. If they do know of such a Default or Event of
         Default, the certificate shall describe such Default or Event of
         Default and the efforts to remedy or obtain a waiver of the same.

S 2.13.  Defeasance and Covenant Defeasance.

                  With respect to the Notes issued under this Supplemental
Indenture, both Section 13.1 and Section 13.2 shall be inapplicable to the
Notes.

S 2.14.  Subordination.

                  With respect to the Notes issued under this Supplemental
Indenture, Article 15 of the Indenture is hereby replaced in its entirety as
follows:

                                   ARTICLE 15

                                  SUBORDINATION

                  S 15.1 Agreement to Subordinate and Ranking.

                           The Company, for itself and its successors, and each
         Holder, by its acceptance of Notes, agree that the payment of the
         principal of or interest on or any other amounts due on the Notes is
         subordinated in right of payment, to the extent and in the manner
         stated in this Article 15, to the prior payment in full of all existing
         and future Senior Debt. The Notes shall rank pari passu with, and shall
         not be senior in right of payment to such other Indebtedness of the
         Company whether outstanding on the date of this Indenture or hereafter
         created, incurred, issued or Guaranteed by the Company, where the
         instrument creating or evidencing such Indebtedness expressly provides
         that such Indebtedness ranks pari passu with the Notes.

                           The Notes shall rank pari passu with the Company's 6%
         Convertible Subordinated Notes due 2006 issued pursuant to that certain
         First Supplemental Indenture dated as of January 23, 2001 and the
         Company's 3.25% Convertible Subordinated Notes due 2021 issued pursuant
         to that certain Second Supplemental Indenture dated as of April 25,
         2001.

                  S 15.2   No Payment on Notes if Designated Senior Debt in
Default.

                           Anything in this Indenture to the contrary
         notwithstanding, no payment on account of principal of or redemption
         of, interest on or other amounts due on the Notes, and no redemption,
         purchase, or other acquisition of the Notes, shall be made by or on
         behalf of the Company, except payments comprised solely of Permitted
         Junior Securities, if (i) a default in the payment of Designated Senior
         Debt occurs and is continuing beyond any applicable period of grace (a
         "Payment Default"), or (ii) a default other than a Payment Default on
         any Designated Senior Debt occurs and is continuing that permits the
         holders of Designated Senior Debt to accelerate its maturity, and the
         trustee receives notice of such default (a "Payment Blockage Notice")
         from the Company or from any holders of Designated Senior Debt or such
         Holder's representative (a "Non-Payment Default"), but only for the
         period (the "Payment Blockage Period") commencing on the date of
         receipt of the Payment Blockage Notice and ending (unless earlier
         terminated by notice given to the Trustee by the holders of such
         Designated Senior Debt) (a) in the case of a Payment Default, upon the
         date on which such Payment Default is cured or waived or ceases to
         exist, and (b) in the case of a Non-Payment Default, the earliest of
         the date on which such Non-Payment Default is cured or waived or ceases
         to exist or 180 days from the date notice is received, if the maturity
         of the Designated Senior Debt has not been accelerated. Upon
         termination of the Payment Blockage Period, payments on account of
         principal of or interest on the Notes (other than, subject to Section
         15.3 hereof, amounts due and payable by reason of the acceleration of
         the maturity of the Notes) and redemptions, purchases or other
         acquisitions shall be made by or on behalf of the Company.
         Notwithstanding anything herein to the contrary, (a) only one Payment
         Blockage Notice may be given with respect to the same Non-Payment
         Default or any other Non-Payment Default on the same issue of
         Designated Senior Debt existing or continuing at the time of such
         Payment Blockage Notice may be given and (b) no new Payment Blockage
         Period may be commenced by the holder or holders of Designated Senior
         Debt or their representative or representatives, unless 360 consecutive
         days have elapsed since the initial effectiveness of the immediately
         preceding Payment Blockage Notice.

                           In the event that, notwithstanding the provisions of
         this Section 15.2, payments are made by or on behalf of the Company in
         contravention of the provisions of this Section 15.2, such payments
         shall be held by the Trustee, any Paying Agent or the holders, as
         applicable, in trust for the benefit of, and shall be paid over to and
         delivered to, the holders of Senior Debt or their representative or the
         trustee under the indenture or other agreement (if any), pursuant to
         which any instruments evidencing any Senior Debt may have been issued
         for application to the payment of all Senior Debt ratably according to
         the aggregate amounts remaining unpaid to the extent necessary to pay
         all Senior Debt in full in accordance with the terms of such Senior
         Debt, after giving effect to any concurrent payment or distribution to
         or for the holders of Senior Debt.

                           The Company shall give prompt written notice to the
         Trustee and any Paying Agent of any default or event of default under
         any Senior Debt or under any agreement pursuant to which any Senior
         Debt may have been issued.

                  S 15.3   Distribution on Acceleration of Notes;  Dissolution
 and Reorganization;  Subrogation of Notes.


                           (a) If the Notes are declared due and payable because
         of the occurrence of an Event of Default, the Company or the Trustee
         shall give prompt written notice to the holders of all Senior Debt or
         to the trustee(s) for such Senior Debt of such acceleration.

                           (b) Upon (i) any acceleration of the principal amount
         due on the Notes because of an Event of Default or (ii) any
         distribution of assets of the Company upon any dissolution, winding up,
         liquidation or reorganization of the Company (whether in bankruptcy,
         insolvency or receivership proceedings or upon an assignment for the
         benefit of creditors or any other dissolution, winding up, liquidation
         or reorganization of the Company):

                           (1) the holders of all Senior Debt shall first be
                  entitled to receive payment in full of the principal thereof,
                  the interest thereon and any other amounts due thereon before
                  the Holders are entitled to receive payment on account of the
                  principal of or interest on or any other amounts due on the
                  Notes, except payments comprised solely of Permitted Junior
                  Securities;

                           (2) any payment or distribution of assets of the
                  Company of any kind or character, whether in cash, property or
                  securities (other than Permitted Junior Securities), to which
                  the holders or the Trustee would be entitled except for the
                  provisions of this Article 15, shall be paid by the
                  liquidating trustee or agent or other Person making such a
                  payment or distribution, directly to the holders of Senior
                  Debt (or their representatives(s) or trustee(s) acting on
                  their behalf), ratably according to the aggregate amounts
                  remaining unpaid on account of the principal of or interest on
                  and other amounts due on the Senior Debt held or represented
                  by each, to the extent necessary to make payment in full of
                  all Senior Debt remaining unpaid, after giving effect to any
                  concurrent payment or distribution to the holders of such
                  Senior Debt; and

                           (3) in the event that, notwithstanding the foregoing,
                  any payment or distribution of assets of the Company of any
                  kind or character, whether in cash, property or securities
                  (other than payments comprised solely of Permitted Junior
                  Securities), shall be received by the Trustee or the holders
                  before all Senior Debt is paid in full, such payment or
                  distribution shall be held in trust for the benefit of, and be
                  paid over to upon request by a holder of the Senior Debt, the
                  holders of the Senior Debt remaining unpaid (or their
                  representatives) or trustee(s) acting on their behalf, ratably
                  as aforesaid, for application to the payment of such Senior
                  Debt until all such Senior Debt shall have been paid in full,
                  after giving effect to any concurrent payment or distribution
                  to the holders of such Senior Debt.

                           Subject to the payment in full of all Senior Debt,
         the Holders shall be subrogated to the rights of the holders of Senior
         Debt to receive payments or distributions of cash, property or
         securities of the Company applicable to the Senior Debt until the
         principal of and interest on the Notes shall be paid in full and, for
         purposes of such subrogation, no such payments or distributions to the
         holders of Senior Debt of cash, property or securities which otherwise
         would have been payable or distributable to Holders shall, as between
         the Company, its creditors other than the holders of Senior Debt, and
         the Holders, be deemed to be a payment by the Company to or on account
         of the Senior Debt, it being understood that the provisions of this
         Article 15 are and are intended solely for the purpose of defining the
         relative rights of the Holders, on the one hand, and the holders of
         Senior Debt, on the other hand.

                           Nothing contained in this Article 15 or elsewhere in
         this Indenture or in the Notes is intended to or shall (i) impair, as
         between the Company and its creditors other than the holders of Senior
         Debt, the obligation of the Company, which is absolute and
         unconditional, to pay to the Holders the principal of and interest on
         the Notes as and when the same shall become due and payable in
         accordance with the terms of the Notes or is intended to or (ii) affect
         the relative rights of the Holders and creditors of the Company other
         than holders of Senior Debt or, as between the Company and the Trustee,
         the obligations of the Company to the Trustee, or (iii) prevent the
         Trustee or the Holders from exercising all remedies otherwise permitted
         by applicable law upon default under this Indenture, subject to the
         rights, if any, under this Article 15 of the holders of Senior Debt in
         respect of cash, property and securities of the Company received upon
         the exercise of any such remedy.

                           Upon distribution of assets of the Company referred
         to in this Article 15, the Trustee, subject to the provisions of
         Sections 6.1 and 6.2 of this Indenture, and the Holders shall be
         entitled to rely upon a certificate of the liquidating trustee or agent
         or other Person making any distribution to the Trustee or to the
         Holders for the purpose of ascertaining the Persons entitled to
         participate in such distribution, the holders of the Senior Debt and
         other indebtedness of the Company, the amount thereof or payable
         thereon, the amount or amounts paid or distributed thereon and all
         other facts pertinent thereto or to this Article 15. The Trustee,
         however, shall not be deemed to owe any fiduciary duty to the holders
         of Senior Debt. Nothing contained in this Article 15 or elsewhere in
         this Indenture, or in any of the Notes, shall prevent the good faith
         application by the Trustee of any moneys which were deposited with it
         hereunder, prior to its receipt of written notice of facts which would
         prohibit such application, for the purpose of the payment of or on
         account of the principal of or interest on, the Notes unless, prior to
         the date on which such application is made by the Trustee, the Trustee
         shall be charged with notice under Section 15.3(d) hereof of the facts
         which would prohibit the making of such application.

                           (c) The provisions of this Article 15 shall not be
         applicable to any cash, properties or securities received by the
         Trustee or by any Holder when received as a holder of Senior Debt and
         nothing in Section 6.13 hereof or elsewhere in this Indenture shall
         deprive the Trustee or such Holder of any of its rights as such holder.

                           (d) The Company shall give prompt written notice to
         the Trustee of any fact known to the Company which would prohibit the
         making of any payment of money to or by the Trustee in respect of the
         Notes pursuant to the provisions of this Article 15. The Trustee,
         subject to the provisions of Sections 6.1 and 6.2 hereof, shall be
         entitled to assume that no such fact exists unless the Company or any
         holder of Senior Debt or any trustee therefor has given such notice to
         the Trustee. Notwithstanding the provisions of this Article 15 or any
         other provisions of this Indenture, the Trustee shall not be charged
         with knowledge of the existence of any fact which would prohibit the
         making of any payment of monies to or by the Trustee in respect of the
         Notes pursuant to the provisions in this Article 15, unless, and until
         three Business Days after, the Trustee shall have received written
         notice thereof from the Company or any Holder or holders of Senior Debt
         or from any trustee therefor; and, prior to the receipt of any such
         written notice, the Trustee, subject to the provisions of Sections 6.1
         and 6.2 hereof, shall be entitled in all respects conclusively to
         assume that no such facts exist; provided that if on a date not less
         than three Business Days immediately preceding the date upon which by
         the terms hereof any such monies may become payable for any purpose
         (including, without limitation, the principal of or interest on any
         Note), the Trustee shall not have received with respect to such monies
         the notice provided for in this Section 15.3(d), than 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.

                           The Trustee 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 Debt (or a trustee on behalf of such holder) to
         establish that such notice has been given by a holder of Senior Debt
         (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
         Debt to participate in any payment or distribution pursuant to this
         Article 15, the Trustee may request such Person to furnish evidence to
         the reasonable satisfaction of the Trustee as to the amount of Senior
         Debt 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 15, 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; nor shall the Trustee be charged with
         knowledge of the curing or waiving of any default of the character
         specified in Section 15.2 hereof or that any event or any condition
         preventing any payment in respect of the Notes shall have ceased to
         exist, unless and until the Trustee shall have received an Officers'
         Certificate to such effect.

                           (e) The provisions of this Section 15.3 applicable to
         the Trustee shall also apply to any Paying Agent for the Company.

                  S 15.4   Reliance by Senior Debt on Subordination Provisions.

                           Each Holder of any Note by his acceptance thereof
         acknowledges and agrees that the foregoing subordination provisions
         are, and are intended to be, an inducement and a consideration for each
         holder of any Senior Debt, whether such Senior Debt was created or
         acquired before or after the issuance of the Notes, to acquire and
         continue to hold, or to continue to hold, such Senior Debt, and such
         holder of Senior Debt shall be deemed conclusively to have relied on
         such subordination provisions in acquiring and continuing to hold, or
         in continuing to hold, such Senior Debt. Notice of any default in the
         payment of any Senior Debt, except as expressly stated in this Article
         15, and notice of acceptance of the provisions hereof are hereby
         expressly waived. Except as otherwise expressly provided herein, no
         waiver, forbearance or release by any holder of Senior Debt under such
         Senior Debt or under this Article 15 shall constitute a release of any
         of the obligations or liabilities of the Trustee or Holders of the
         Notes provided in this Article 15.

                  S 15.5   No Waiver of Subordination Provisions.

                           Except as otherwise expressly provided herein, no
         right of any present or future holder of any Senior Debt 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
         Company or by any act or failure to act, in good faith, by any such
         holder, or by any noncompliance by the Company with the terms,
         provisions and covenants of this Indenture, regardless of any knowledge
         thereof any such holder may have or be otherwise charged with.

                           Without in any way limiting the generality of the
         foregoing paragraph, the holders of Senior Debt may, at any time and
         from time to time, without the consent of, or notice to, the Trustee or
         the Holders of the Notes, without incurring responsibility to the
         Holders of the Notes and without impairing or releasing the
         subordination provided in this Article 15 or the obligations hereunder
         of the Holders of the Notes to the holders of Senior Debt, do any one
         or more of the following: (i) change the manner, place or terms of
         payment of, or renew or alter, Senior Debt, or otherwise amend or
         supplement in any manner Senior Debt or any instrument evidencing the
         same or any agreement under which Senior Debt is outstanding; (ii)
         sell, exchange, release or otherwise dispose of any property pledged,
         mortgaged or otherwise securing Senior Debt; (iii) release any Person
         liable in any manner for the collection of Senior Debt; and (iv)
         exercise or refrain from exercising any rights against the Company or
         any other Person.

                  S 15.6   Trustee's Relation to Senior Debt.

                           The Trustee in its individual capacity shall be
         entitled to all the rights set forth in this Article 15 in respect of
         any Senior Debt at any time held by it, to the same extent as any
         holder of Senior Debt, and nothing in Section 6.13 hereof or elsewhere
         in this Indenture shall deprive the Trustee of any of its rights as
         such holder.

                           With respect to the holders of Senior Debt, the
         Trustee undertakes to perform or to observe only such of its covenants
         and obligation, as are specifically set forth in this Article 15, and
         no implied covenants or obligations with respect to the holders of
         Senior Debt shall be read into this Indenture against the Trustee. The
         Trustee shall not owe any fiduciary duty to the holders of Senior Debt
         but shall have only such obligations to such holders as are expressly
         set forth in this Article 15.

                           Each Holder of a Note by his acceptance thereof
         authorizes and directs the Trustee on his behalf to take such action as
         may be necessary or appropriate to effectuate the subordination
         provided in this Article 15 and appoints the Trustee his
         attorney-in-fact for any and all such purposes, including, in the event
         of any dissolution, winding up or liquidation or reorganization under
         any applicable bankruptcy law of the Company (whether in bankruptcy,
         insolvency or receivership proceedings or otherwise), the timely filing
         of a claim for the unpaid balance of such Holder's Notes in the form
         required in such proceedings and the causing of such claim to be
         approved. If the Trustee does not file a claim or proof of debt in the
         form required in such proceedings prior to 30 days before the
         expiration of the time to file such claims or proofs, then any Holder
         or holders of Senior Debt or their representative or representatives
         shall have the right to demand, sue for, collect, receive and receipt
         for the payments and distributions in respect of the Notes which are
         required to be paid or delivered to the holders of Senior Debt as
         provided in this Article 15 and to file and prove all claims therefore
         and to take all such other action in the name of the holders or
         otherwise, as such holders of Senior Debt or representative thereof may
         determine to be necessary or appropriate for the enforcement of the
         provisions of this Article 15.

                  S 15.7   Other Provisions Subject Hereto.

                           Expect as expressly stated in this Article 15,
         notwithstanding anything contained in this Indenture to the contrary,
         all the provisions of this Indenture and the Notes are subject to the
         provisions of this Article 15. However, nothing in this Article 15
         shall apply to or adversely affect the claims of, or payment, to, the
         Trustee pursuant to Section 6.7 hereof. Notwithstanding the foregoing,
         the failure to make a payment on account of principal of or interest on
         the Notes by reason of any provision of this Article 15 shall not be
         construed as preventing the occurrence of an Event of Default under
         Section 5.1 hereof.

III.                                ARTICLE 3

                                  MISCELLANEOUS

S 3.1.   Effect of Headings.

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

S 3.2.   Successors and Assigns.

                  All covenants and agreements in this Supplemental Indenture by
the Company shall bind its successors and assigns, whether so expressed or not.

S 3.3.   Separability Clause.

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

S 3.4.   Governing Law.

be governed by and construed in accordance with the laws of the State of New
York without giving effect to any conflicts of law provisions (other than

                                 [Back of Note]
                   6% Convertible Subordinated Notes due 2006

                  [INSERT IN GLOBAL NOTES] [This Security is in global form
within the meaning of the Indenture hereinafter referred to and is registered in
the name of a Common Depositary or a U.S. Depositary. Unless and until it is
exchanged in whole or in part for Securities in certificated form, this Security
may not be transferred except as a whole by the Common Depositary or a U.S.
Depositary or by a nominee of the Common Depositary or a nominee of the U.S.
Depositary as the case may be.]

                  Unless and until it is exchanged in whole or in part for Notes
in definitive form, this Note may not be transferred except as a whole by the
U.S. Depository to a nominee of the U.S. Depository or by a nominee of the U.S.
Depository to the U.S. Depository or another nominee of the U.S. Depository or
by the U.S. Depository or any such nominee to a successor U.S. Depository or a
nominee of such successor U.S. Depository. Unless this certificate is presented
by an authorized representative of The Depository Trust Company (55 Water
Street, New York, New York) ("DTC"), to the issuer or its agent for registration
of transfer, exchange or payment, and any certificate issued is registered in
the name of Cede & Co. or such other name as may be requested by an authorized
representative of DTC (and any payment is made to Cede & Co. or such other
entity as may be requested by an authorized representative of DTC), ANY
TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON
IS WRONGFUL inasmuch as the registered owner hereof, Cede & Co., has an interest
herein.

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

                  1. INTEREST. Adelphia Communications Corporation, a Delaware
corporation (the "Company") promises to pay interest on the principal amount of
this Note at 6% per annum from January 23, 2001 until February 15, 2006. The
Company shall pay interest, semi-annually in arrears on February 15 and August
15 of each year, or if any such day is not a Business Day, on the next
succeeding Business Day (each an "Interest Payment Date"). Interest on the Notes
will accrue from the most recent date to which interest has been paid or, if no
interest has been paid, from the date of issuance; provided that if there is no
existing Default in the payment of interest, [and if this Note is authenticated
between a record date referred to on the face hereof and the next succeeding
Interest Payment Date, interest shall accrue from such next succeeding Interest
Payment Date; provided, further, that the first Interest Payment Date shall be
August 15, 2001]. The Company shall pay interest (including post-petition
interest in any proceeding under any Bankruptcy Law) on overdue principal from
time to time on demand at a rate equal to the per annum rate on the Notes then
in effect; it shall pay interest (including post-petition interest in any
proceeding under any Bankruptcy Law) on overdue installments of interest
(without regard to any applicable grace periods) from time to time on demand at
the same rate to the extent lawful. Interest will be computed on the basis of a
360-day year of twelve 30-day months.

                  2. METHOD OF PAYMENT. The Company shall make payments in
respect of the Notes represented by the Global Notes (including principal and
interest) by wire transfer of immediately available funds to the accounts
specified by the Note Custodian. With respect to Notes issued in definitive
form, the Company shall make all payments of principal and interest by mailing a
check to each such Holder's registered address, provided that all payments with
respect to Notes having an aggregate principal amount of $100,000 or more, the
Holders of which have given wire transfer instructions to the Company at least
ten business days prior to the applicable payment date, will be required to be
made by wire transfer of immediately available funds to the accounts specified
by the Holders thereof. The Notes represented by the Global Notes are expected
to be eligible to trade in DTC's Same-Day Funds Settlement System, and any
permitted secondary market trading activity in such notes will, therefore, be
required by DTC to be settled in immediately available funds. The Company
expects that secondary trading in the Definitive Notes also will be settled in
immediately available funds.

                  3.  PAYING  AGENT AND  SECURITY  REGISTRAR.  Initially,  The
Bank of New York, the Trustee under the Indenture, will act as Paying Agent,
Conversion Agent and Security Registrar. The Notes may be presented for
registration of transfer and exchange at the offices of the Security Registrar.
The Company may change any Paying Agent, Conversion Agent or Security Registrar
without notice to any Holder. The Company or any of its Subsidiaries may act in
any such capacity.

                  4. INDENTURE. The Company issued the Notes under an Indenture
dated as of January 23, 2001 (the "Base Indenture") as supplemented by a Third
Supplemental Indenture dated as of October ___, 2001 (the "Supplemental
Indenture" and, together with the Base Indenture, the "Indenture" ) between the
Company and the Trustee. The terms of the Notes include those stated in the
Indenture and those made part of the Indenture by reference to the Trust
Indenture Act of 1939, as amended (15 U.S. Code SS 77aaa-77bbbb). The Notes are
subject to all such terms, and Holders are referred to the Indenture and such
Act for a statement of such terms. The Notes issued under the Indenture are
subordinated unsecured obligations of the Company limited to $167,376,000 in
aggregate principal amount.

                  5.       OPTIONAL REDEMPTION.

                  At any time on or after February 16, 2004, the Company may
redeem any portion of the Notes, in whole or in part, on at least 30 days, but
no more than 60 days' notice at the following prices (expressed as a percentage
of the principal amount), together with accrued and unpaid interest to, but
excluding, the redemption date:

         Redemption Period                                   Redemption Price
         -----------------                                   ----------------
February 16, 2004 through February 14, 2005                       102.40%
February 15, 2005 through February 14, 2006                       101.20%

and 100.00% of the principal amount on February 15, 2006.

                  In the event the Company redeems less than all of the
outstanding Notes, the Notes to be redeemed shall be selected by the Trustee in
accordance with Section 11.3 of the Indenture. In the event a portion of an
outstanding Note is selected for redemption and such Note is converted in part
after such selection, the converted portion of such Note shall be deemed (so far
as may be) to be the portion to be selected for redemption in accordance with
Section 11.3 of the Indenture. The Company may not give notice of any redemption
if the Company has defaulted in payment of interest and the default is
continuing.

                  6.       NOTICE OF REDEMPTION.

                  Notice of redemption will be mailed at least 30 days but not
more than 60 days before the redemption date to each Holder of the Notes to be
redeemed at such Holder's address of record. The Notes in denominations larger
than $1,000 may be redeemed in part but only in integral multiples of $1,000. In
the event of a redemption of less than all of the Notes, the Notes will be
chosen for redemption by the Trustee in accordance with the Indenture. On and
after the redemption date, interest ceases to accrue on the Notes or portions of
them called for redemption.

                  If this Note is redeemed subsequent to a Record Date with
respect to any Interest Payment Date specified above and on or prior to such
Interest Payment Date, then any accrued interest will be paid to the Person in
whose name this Note is registered at the close of business on such Record Date.

                  7.       MANDATORY  REDEMPTION.  Except as set forth in
paragraph 8 below, the Company shall not be required to make mandatory
redemption payments with respect to the Notes. There are no sinking fund
payments with respect to the Notes.

                  8. REPURCHASE AT OPTION OF HOLDER. Within 10 days of the
occurrence of a Fundamental Change the Company shall notify the Trustee and each
Holder in writing of such occurrence and shall make an offer to purchase (the
"Fundamental Change Offer") all or any part of each Holder's Notes at a purchase
price equal to 100% of the principal amount thereof plus any accrued and unpaid
interest thereon to the purchase date, which shall be a Business Day no later
than 30 Business Days after the date of the notice of the Fundamental Change
(the "Fundamental Change Payment Date"). Such right to require the repurchase of
Notes shall not continue after discharge of the Company from its obligations
with respect to the Notes. The Board of Directors of the Company may not waive
this provision.

                  9. SUBORDINATION. The payment of the principal of, interest on
or any other amounts due on the Notes is subordinated in right of payment to all
existing and future Senior Debt of the Company, as described in the Indenture.
Each Holder, by accepting a Note, agrees to such subordination and authorizes
and directs the Trustee on its behalf to take such action as may be necessary or
appropriate to effectuate the subordination so provided and appoints the Trustee
as its attorney-in-fact for such purpose.

                  10. CONVERSION. The holder of any Note has the right,
exercisable at any time after the original issuance of the Note and before the
close of business (New York time) on the Business Day immediately preceding the
date of the Note's maturity, to convert the principal amount thereof (or any
portion thereof that is an integral multiple of $1,000) into shares of Class A
Common Stock (or Class B Common Stock if the Notes are held by a member or
affiliate of the Rigas Family), at the initial Conversion Price of $55.49 per
share, subject to adjustment under certain circumstances as set forth in the
Indenture, except that if a Note is called for redemption, the conversion right
will terminate at the close of business on the Business Day immediately
preceding the date fixed for redemption (unless the Company shall default in
making the redemption payment when it becomes due, in which case the conversion
right shall terminate on the date such default is cured).

                  To convert a Note, a holder must (1) complete and sign a
conversion notice for Class A Common Stock substantially in the form set forth
below, or if the holder is a member or affiliate of the Rigas Family complete
and sign a conversion notice for Class B Common Stock substantially in the form
set forth below, (2) surrender the Note to a Conversion Agent, (3) furnish
appropriate endorsements or transfer documents if required by the Registrar or
Conversion Agent and (4) pay any transfer or similar tax, if required. No
payment or other adjustment for accrued interest or dividends on any Class A
Common Stock (or Class B Common Stock if the Notes are held by a member or
affiliate of the Rigas Family), issued upon conversion of the Notes shall be
made by the Company. If any Notes are converted during any period after any
Record Date for the payment of an installment of interest but before the next
Interest Payment Date, interest for such notes will be paid on the next Interest
Payment Date, notwithstanding such conversion, to the Holders of such Notes. Any
Notes that are, however, delivered to the Company for conversion after any
Record Date but before the next Interest Payment Date must, except as described
in the next sentence, be accompanied by a payment equal to the interest payable
on such Interest Payment Date on the principal amount of Notes being converted.
The payment to the Company described in the preceding sentence shall not be
required if, during that period between a Record Date and the next Interest
Payment Date, a conversion occurs on or after the date that the Company has
issued a redemption notice and prior to the date of redemption stated in such
notice. No fractional shares will be issued upon conversion, but a cash
adjustment will be made for any fractional shares.

                  A Note in respect of which a Holder has delivered an "Option
of Holder to Elect Purchase" form appearing below exercising the option of such
Holder to require the Company to purchase such Note may be converted only if the
notice of exercise is withdrawn as provided above and in accordance with the
terms of the Indenture. The above description of conversion of the Notes is
qualified by reference to, and is subject in its entirety by, the more complete
description thereof contained in the Indenture.

                  11. DENOMINATIONS,  TRANSFER,  EXCHANGE.  The Notes are in
registered form without coupons in minimum denominations of $1,000 and
integral multiples of $1,000 in excess thereof. The transfer of Notes may be
registered and Notes may be exchanged as provided in the Indenture.

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

                  13. AMENDMENT, SUPPLEMENT AND WAIVER. Subject to certain
exceptions, the Indenture with respect to the Notes or the Notes may be amended
or supplemented with the written consent of the Holders of a majority in
principal amount of the Notes, and any existing default or compliance with any
provision of the Indenture with respect to the Notes or the Notes may be waived
with the consent of the Holders of a majority in principal amount of the Notes,
voting as a single class. Without the consent of any Holder of the Notes, the
Indenture with respect to the Notes or the Notes may be amended or supplemented
to, in addition to other events more fully described in the Indenture, cure any
ambiguity, defect or inconsistency, to establish the form or terms of the Notes
as permitted by Sections 2.1 and 3.1 of the Indenture, to evidence the
succession of another corporation to the Company and the assumption by any such
successor of the covenants of the Company contained in the Indenture, to secure
the Notes, to make any change that does not materially adversely affect the
interests of any Holder under the Indenture, to qualify, or maintain the
qualification of the Indenture under the Trust Indenture Act.

                  14. DEFAULTS AND REMEDIES. An Event of Default with respect to
the Notes occurs if: (i) the Company defaults in the payment when due of any
interest on, any such series of Notes and such default continues for a period of
30 days; (ii) the Company defaults in the payment of the principal of any such
series of Notes at its maturity; (iii) the Company fails to observe or perform
any other covenant, representation, warranty or other agreement in the Indenture
or the Notes for 60 days after written notice to the Company by the Trustee or
the Holders of at least 25% in principal amount of such series of Notes then
outstanding; (iv) the Company fails to pay when due principal, interest or
premium aggregating $10,000,000 or more with respect to any Indebtedness of the
Company or any Restricted Subsidiary, or the acceleration of any such
Indebtedness which default shall not be cured or waived, or such acceleration
shall not be rescinded or annulled, within 10 days after written notice; (v) a
final judgment or final judgments for the payment of money are entered by a
court or courts of competent jurisdiction against the Company or any of its
Restricted Subsidiaries and such judgment or judgments remain undischarged for a
period (during which execution shall not be effectively stayed) of 60 days,
provided that the aggregate of all such judgments exceeds $10,000,000; or (vi)
the Company or any Restricted Subsidiary with liabilities of greater than
$10,000,000 under GAAP as of the date of the event described in this clause,
pursuant to or within the meaning of Bankruptcy Law: (a) commences a voluntary
case, (b) consents to the entry of an order for relief against it in an
involuntary case, (c) consents to the appointment of a Custodian of it or for
all or substantially all of its property, or (d) makes a general assignment for
the benefit of its creditors, (vii) a court of competent jurisdiction enters an
order or decree under any Bankruptcy Law that: (a) is for relief against the
Company, or any Restricted Subsidiary with liabilities of greater than
$10,000,000 under GAAP as of the effective date of such order or decree in an
involuntary case, (b) appoints a custodian of the Company, or any Restricted
Subsidiary of Restricted Subsidiary with liabilities of greater than $10,000,000
under GAAP as of the effective date of such order or decree or for all or
substantially all of its property or (c) orders the liquidation of the Company,
or any Restricted Subsidiary with liabilities greater than $10,000,000 under
GAAP as of the effective date of such order or decree; and the order or decree
remains unstayed and in effect for 60 consecutive days. If any Event of Default
occurs and is continuing, the Trustee or the Holders of at least 25% in
principal amount of the then outstanding series of Notes may declare all of such
Notes to be due and payable immediately. Notwithstanding the foregoing, in the
case an Event of Default specified in clauses (6) or (7) of Section 5.1 of the
Indenture occurs with respect to the Company, or a Restricted Subsidiary with
liabilities of greater than $10,000,000 under GAAP as of the effective date of
such order or decree, all outstanding series of Notes will become due and
payable without further action or notice. Holders of such series of Notes may
not enforce the Indenture with respect to such series of Notes or such series of
Notes except as provided in the Indenture. Subject to certain limitations,
Holders of a majority in principal amount of the then outstanding series of
Notes may direct the Trustee in its exercise of any trust or power. The Trustee
may withhold from Holders of such series of Notes notice of any continuing
Default or Event of Default (except a Default or Event of Default relating to
the payment of principal or interest) if it determines that withholding notice
is in their interest. The Holders of not less than a majority in aggregate
principal amount of the such series of Notes then outstanding by notice to the
Trustee may on behalf of the Holders of all of the Notes waive any existing
Default or Event of Default and its consequences under the Indenture, except a
continuing Default or Event of Default in the payment of the principal of or
interest on, such series of Notes (provided, however, that the Holders of a
majority in aggregate principal amount of the then outstanding series of Notes
may rescind an acceleration and its consequence, including any related payment
default) or a default with respect to any covenant or provision which cannot be
modified or amended without the consent of the Holder of each outstanding Note
affected.

                  The Company is required to deliver to the Trustee annually a
statement regarding compliance with the Indenture, and the Company is required,
upon becoming aware of any Default or Event of Default, to deliver to the
Trustee a statement specifying such Default or Event of Default and what action
the Company is taking or proposes to take thereto.

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

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

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

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

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

                  The Company shall furnish to any Holder upon written request
and without charge a copy of the Indenture. Requests may be made to:

                           Adelphia Communications Corporation
                           One North Main Street
