                                    unable to continue as Depository for the

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

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.

                  (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

on the Global Notes, by the Trustee or the Note Custodian, at the direction of
the Trustee, to reflect such reduction.

                                    payment of a sum sufficient to cover any
                                    transfer tax or similar governmental charge
                                    payable in connection therewith (other than

                                    Notes shall be the valid obligations of the
                                    Company, evidencing the same debt, and
                                    entitled to the same benefits under this

                                    Note for the purpose of receiving payment of
                                    principal of and interest on such Notes, and
                                    neither the Trustee, any Agent nor the

ss.2.5.   Change of Control Offer.
          -----------------------

                  Within 50 days of (i) the proposed occurrence of a Change of
Control or (ii) the occurrence of a Change of Control Triggering Event, the
Company shall notify the Trustee in writing of such proposed occurrence or
occurrence, as the case may be, and shall make an offer to purchase (the "Change
of Control Offer") the Notes at a purchase price equal to 100% of the principal
amount thereof plus any accrued and unpaid interest thereon to the Change of
Control Payment Date (as hereinafter defined) (the "Change of Control Purchase
Price") in accordance with the procedures set forth in this covenant.

                  Within 50 days of (i) the proposed occurrence of a Change of
Control or (ii) the occurrence of a Change of Control Triggering Event, the
Company also shall (a) cause a notice of the Change of Control Offer to be sent
at least once to the Dow Jones News Service or similar business news service in
the United States and (b) send by first-class mail, postage prepaid, to the
Trustee and to each holder of the Notes, at his address appearing in the
register of the Notes maintained by the Security Registrar, a notice stating:

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

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

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

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

                           (5) that holders accepting the offer to have their
                  Notes purchased pursuant to a Change of Control 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 Change of Control 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
                  Change of Control 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 Change of Control Offer or effect withdrawal of
                  such acceptance.

                  Notwithstanding  any other  provision of this Section 2.5
, in the case of a notice of a Change of
Control Offer that is being furnished by the Company with respect to a proposed
Change of Control that has not yet actually occurred, the Company may specify in
such notice that holders of the Notes shall be required to notify the Company,
by a date not earlier than the date (the "Proposed Change of Control Response
Date") which is 30 days from the date of such notice, as to whether such holders
will tender their Notes for payment pursuant to the Change of Control Offer and
to notify the Company of the principal amount of such Notes to be so tendered
(with the failure of any holder to so notify the Company within such 30-day
period to be deemed an election of such holder not to accept such Change of
Control Offer). In such event, the Company shall have the option, to be
exercised by a subsequent written notice to be sent, no later than 15 days after
the Proposed Change of Control Response Date, to the same Persons to whom the
original notice of the Change of Control Offer was sent, to cancel or otherwise
effect the termination of the proposed Change of Control and to rescind the
related Change of Control Offer, in which case the then outstanding Change of
Control Offer shall be deemed to be null and void and of no further effect.

                  On the Change of Control Payment Date, the Company shall (a)
accept for payment Notes or portions thereof tendered pursuant to the Change of
Control 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 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.

                  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 Change of Control 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 a Change of
Control Offer, the Company will comply with all applicable tender offer rules
including Rule 14e-1 under the Exchange Act, to the extent applicable.

                                                     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.

ss.2.7.   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 resulting from certain events of bankruptcy, insolvency or
reorganization) 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
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 2.6(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.

ss.2.8.   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; (ii) immediately before and immediately after
giving effect to such transaction, no Default or Event of Default shall have
occurred and be continuing; and (iii) immediately after giving effect to such
transaction on a pro forma basis for the most recent quarter, the pro forma
Consolidated Fixed Charge Ratio of the surviving entity shall be at least 1:1;
provided that, if the Consolidated Fixed Charge Ratio of the Company for the
most recent quarter preceding such transaction is within the range set forth in
Column A below, then the pro forma Consolidated Fixed Charge Ratio of the
surviving entity after giving effect to such transaction shall be at least equal
to the greater of the percentage of the Consolidated Fixed Charge Ratio of the
Company for the most recent quarter preceding such transaction set forth in
Column B below or the ratio set forth in Column C below:

<TABLE>
<CAPTION>

                         A                                       B                   C
                         -                                       -                   -

<S>                                                             <C>               <C>
                1.1111:1 to 1.4999:1                             90%               1.00:1
                1.5 and higher                                   80%               1.35:1
</TABLE>

and provided, further, that if the pro forma Consolidated Fixed Charge Ratio of
the surviving entity is 2:1 or more, the calculation in the preceding proviso
shall be inapplicable and such transaction shall be deemed to have complied with
the requirements of such proviso.

                  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.

ss.2.9.   Supplemental Indentures.
          -----------------------

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

                  ss.9.7     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.

ss.2.10.  Covenants.
          ---------

entirety as follows:

                                   ARTICLE 10

                                    COVENANTS

ss.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.

ss.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 ss. 314(a).

ss.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.

ss.10.4   Limitation on Transactions with Affiliates.
          ------------------------------------------

                  The Company shall not, and shall not permit any Restricted
Subsidiary to, engage in any transaction with any Affiliate upon terms which
would be any less favorable than those obtainable by the Company or a Restricted
Subsidiary in a comparable arm's-length transaction with a Person which is not
an Affiliate. The Company shall not, and shall not permit any Restricted
Subsidiary to, engage in any transaction (or series of related transactions)
involving in the aggregate $1,000,000 or more with any Affiliate except for (i)
the making of any Restricted Payment, (ii) any transaction or series of
transactions between the Company and one or more of its Restricted Subsidiaries
or between two or more of its Restricted Subsidiaries (provided that no more
than 5% of the equity interest in any of its Restricted Subsidiaries is owned by
an Affiliate), and (iii) the payment of compensation (including, without
limitation, amounts paid pursuant to employee benefit plans) for the personal
services of officers, directors and employees of the Company or any of its
Restricted Subsidiaries, so long as the Board of Directors of the Company in
good faith shall have approved the terms thereof and deemed the services
theretofore or thereafter to be performed for such compensation or fees to be
fair consideration therefor; and provided further that for any Asset Sale, or a
sale, transfer or other disposition (other than to the Company or any of its
Restricted Subsidiaries) of an interest in a Restricted Investment, involving an
amount greater than $25,000,000, such Asset Sale or transfer of interest in a
Restricted Investment is for fair value as determined by an opinion of a
nationally recognized investment banking firm filed with the Trustee.
Notwithstanding the foregoing, this provision shall not prohibit any such
transaction which is determined by the independent members of the Board of
Directors of the Company, in their reasonable, good faith judgment (as evidenced
by a Board Resolution filed with the Trustee) to be (a) in the best interests of
the Company or such Restricted Subsidiary, and (b) upon terms which would be
obtainable by the Company or a Restricted Subsidiary in a comparable
arm's-length transaction with a Person which is not an Affiliate.

ss.10.5   Limitation on Indebtedness.
          --------------------------

                  The Company shall not, and shall not permit any Restricted
Subsidiary to, directly or indirectly, create, incur, issue, assume or become
liable for, contingently or otherwise (collectively an "incurrence"), any
Indebtedness unless, after giving effect to such incurrence on a pro forma
basis, Indebtedness of the Company and its Restricted Subsidiaries, on a
consolidated basis, shall not be more than the product of the Annualized Pro
Forma EBITDA for the latest fiscal quarter preceding such incurrence for which
financial statements are available, multiplied by 8.75.

                  Notwithstanding the above, this provision will not limit the
incurrence of Indebtedness which is incurred by the Company or its Restricted
Subsidiaries for working capital purposes or capital expenditures with respect
to plant, property and equipment of the Company and its Restricted Subsidiaries
in an aggregate amount not to exceed $50,000,000. Further, this provision will
not limit Permitted Refinancing Indebtedness, subject to the provisions of
Section 10.6.

ss.10.6   Limitation on Restricted Payments.
          ---------------------------------

                  So long as any of the Notes remain outstanding, the Company
shall not make, and shall not permit any Restricted Subsidiary to make, any
Restricted Payment if (a) at the time of such proposed Restricted Payment, a
Default or Event of Default shall have occurred and be continuing or shall occur
as a consequence of such Restricted Payment, or (b) immediately after giving
effect to any such Restricted Payment, the aggregate of all Restricted Payments
which shall have been made on or after January 1, 1993 (the amount of any
Restricted Payment, if other than cash, to be based upon fair market value as
determined in good faith by the Company's Board of Directors whose determination
shall be conclusive) would exceed an amount equal to the greater of (i) the sum
of $5,000,000 or (ii) the difference between (a) the Cumulative Credit and (b)
the sum of the aggregate amount of all Restricted Payments, and all Permitted
Investments made pursuant to clause (v) of the definition of "Permitted
Investments," made on or after January 1, 1993 plus 1.2 times Cumulative
Interest Expense.

ss.10.7   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, (i) 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, and (ii) so long as the Notes have not been registered pursuant to the
Registration Rights Agreement, upon the request of a Noteholder, to provide
information required to be delivered under Rule 144A(d)(4) under the Securities
Act to such Noteholder and its prospective purchasers designated by such
Noteholder.

ss.10.8   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.

ss.10.9   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.

ss.10.10  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.

ss.10.11   Covenant to Secure Notes Equally.
           --------------------------------

                  Except for Liens created or assumed by the Company in
connection with the acquisition of real property or equipment to be used by the
Company in the operation of its business which do not secure Indebtedness in
excess of the purchase price of such real property or equipment, the Company
covenants that, if it shall create or assume any Lien upon any of its property
or assets, whether now owned or hereafter acquired, it will make or cause to be
made effective provisions whereby the Notes will be secured by such Lien equally
and ratably with all other Indebtedness of the Company secured by such Lien, as
long as any such other Indebtedness of the Company shall be so secured. The
restriction imposed by this Section 10.11 shall not apply with respect to a
Lien, including a pledge of Capital Stock of a Subsidiary or an Affiliate, to
secure Indebtedness which is an obligation of such Subsidiary or Affiliate and
not an obligation of the Company.

Trustee or Paying Agent.

HARRIS TRUST COMPANY OF NEW YORK,
as Trustee

By:
      Authorized Signature

<PAGE>

                                 [Back of Note]

                          9-3/8% Senior Notes due 2009

                  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
Depository to a nominee of the Depository or by a nominee of the Depository to
the Depository or another nominee of the Depository or by the Depository or any
such nominee to a successor Depository or a nominee of such successor
Depository. 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.1

                  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 9-3/8% per annum from November 16, 1999 until November 15, 2009.
The Company shall pay interest, semi-annually in arrears on May 15 and November
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
May 15, 2000. 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,
Harris Trust Company of New York, the Trustee under the Indenture, will act as
Paying 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 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 April 28, 1999 (the "Base Indenture") as supplemented by a Second
Supplemental Indenture dated as of November 16, 1999 (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.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
senior unsecured obligations of the Company limited to $500 million in aggregate
principal amount.

                  5.       MANDATORY  REDEMPTION.  Except as set forth in
paragraph 6 below, the Company shall not be required to make mandatory
redemption payments with respect to the Notes.

                  6. REPURCHASE AT OPTION OF HOLDER. Within 50 days of (i) the
proposed occurrence of a Change of Control or (ii) the occurrence of Change of
Control Triggering Event, the Company shall be required to make an offer (a
"Change of Control Offer") to repurchase all or any part (equal to $1,000 or an
integral multiple thereof) of each Holder's Notes at a purchase price equal to
100% of the principal amount thereof plus accrued and unpaid interest and
Liquidated Damages thereon, if any, to the date of purchase, which date shall be
no later than 50 days from the date such notice is mailed (the "Change of
Control Payment Date"). Within 50 days of (i) the proposed occurrence of a
Change of Control or (ii) the occurrence of Change of Control Triggering Event,
the Company shall mail a notice to each Holder setting forth the procedures
governing the Change of Control Offer as required by the Indenture. 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.

                  7.       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.

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

                  9. 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.
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 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, or to qualify, or maintain the qualification of the
Indenture under the Trust Indenture Act.

                  10. 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, or Liquidated Damages with respect to, 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 and
Liquidated Damages, if any, 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.

                  11.      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.

                  12. 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.

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

                  14. 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).

                  15. 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:
