         Upon any application or request by the Corporation to the Trustee to
take any action under any provision of this Indenture, the Corporation shall
furnish to the Trustee such certificates and opinions as may be required under
the Trust Indenture Act. Each such certificate or opinion shall be given in the

comply with the requirements of the Trust Indenture Act and any other
requirements set forth in this Indenture.

condition or covenant provided for in this Indenture shall include:

                                       7
<PAGE>   14

SECTION 103. FORM OF DOCUMENTS DELIVERED TO TRUSTEE.

         In any case where several matters are required to be certified by, or
covered by an opinion of, any specified Person, it is not necessary that all
such matters be certified by, or covered by the opinion of, only one such
Person, or that they be so certified or covered by only one document, but one
such Person may certify or give an opinion with respect to some matters and one
or more other such Persons as to other matters, and any such Person may certify
or give an opinion as to such matters in one or several documents.

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

         Where any Person is required to make, give or execute two or more
applications, requests, consents, certificates, statements, opinions or other
instruments under this Indenture, they may, but need not, be consolidated and
form one instrument.

         Whenever, subsequent to the receipt by the Trustee of any Board
Resolution, Officer's Certificate, Opinion of Counsel or other document or
instrument, a clerical, typographical or other inadvertent or unintentional
error or omission shall be discovered therein, a new document or instrument may
be substituted therefor in corrected form with the same force and effect as if
originally filed in the corrected form and, irrespective of the date or dates of
the actual execution and/or delivery thereof, such substitute document or
instrument shall be deemed to have been executed and/or delivered as of the date
or dates required with respect to the document or instrument for which it is
substituted. Anything in this Indenture to the contrary notwithstanding, if any
such corrective document or instrument indicates that action has been taken by
or at the request of the Corporation which could not have been taken had the
original document or instrument not contained such error or omission, the action
so taken shall not be invalidated or otherwise rendered ineffective but shall be
and remain in full force and effect, except to the extent that such action was a
result of willful misconduct or bad faith. Without limiting the generality of
the foregoing, any Securities issued under the authority of such defective
document or instrument shall nevertheless be the valid obligations of the
Corporation entitled to the benefits of this Indenture equally and ratably with
all other Outstanding Securities, except as aforesaid.

SECTION 104. ACTS OF HOLDERS; RECORD DATES.

                                       8
<PAGE>   15

         Any request, demand, authorization, direction, notice, consent, waiver
or other action provided or permitted by this Indenture to be given, made or
taken by Holders may be embodied in and evidenced by one or more instruments of
substantially similar tenor signed by such Holders in person or by agent duly
appointed in writing; and, except as herein otherwise expressly provided, such
action shall become effective when such instrument or instruments are delivered
to the Trustee and, where it is hereby expressly required, to the Corporation.
Such instrument or instruments (and the action embodied therein and evidenced
thereby) are herein sometimes referred to as the "Act" of the Holders signing
such instrument or instruments. Proof of execution of any such instrument or of
a writing appointing any such agent shall be sufficient for any purpose of this
Indenture and (subject to Section 601) conclusive in favor of the Trustee and
the Corporation, if made in the manner provided in this Section.

         The fact and date of the execution by any Person of any such instrument
or writing may be proved by the affidavit of a witness of such execution or by a
certificate of a notary public or other officer authorized by law to take
acknowledgments of deeds, certifying that the individual signing such instrument
or writing acknowledged to him the execution thereof. Where such execution is by
a signer acting in a capacity other than the signer's individual capacity, such
certificate or affidavit shall also constitute sufficient proof of the signer's
authority. The fact and date of the execution of any such instrument or writing,
or the authority of the Person executing the same, may also be proved in any
other manner which the Trustee deems sufficient.

         The ownership of Securities shall be proved by the Security Register.

         Any request, demand, authorization, direction, notice, consent, waiver
or other Act of the Holder of any Security shall bind every future Holder of the
same Security and the Holder of every Security issued upon the registration of
transfer thereof or in exchange therefor or in lieu thereof in respect of
anything done, omitted or suffered to be done by the Trustee or the Corporation
in reliance thereon, whether or not notation of such action is made upon such
Security.

         The Corporation may set any day as a record date for the purpose of
determining the Holders of Outstanding Securities of any series entitled to
give, make or take any request, demand, authorization, direction, notice,
consent, waiver or other action provided or permitted by this Indenture to be
given, made or taken by Holders of Securities of such series; provided that the
Corporation may not set a record date for, and the provisions of this paragraph
shall not apply with respect to, the giving or making of any notice,
declaration, request or direction referred to in the next paragraph. If any
record date is set pursuant to this paragraph, the Holders of Outstanding
Securities of the relevant series on such record date, and no other Holders,
shall be entitled to take or revoke the relevant action, whether or not such
Holders remain Holders after such record date; provided that no such action
shall be effective hereunder unless taken on or prior to the applicable
Expiration Date by Holders of the requisite principal amount of Outstanding
Securities of such series on such record date. Nothing in this paragraph shall
be construed to prevent the Corporation from setting a new record date for any
action for which a record date has previously been set pursuant to this
paragraph (whereupon the record date

                                       9
<PAGE>   16

previously set shall automatically and with no action by any Person be canceled
and of no effect), and nothing in this paragraph shall be construed to render
ineffective any action taken by Holders of the requisite principal amount of
Outstanding Securities of the relevant series on the date such action is taken.
Promptly after any record date is set pursuant to this paragraph, the
Corporation, at its own expense, shall cause notice of such record date, the
proposed action by Holders and the applicable Expiration Date to be given to the
Trustee in writing and to each Holder of Securities of the relevant series in
the manner set forth in Section 106.

         The Trustee may set any day as a record date for the purpose of
determining the Holders of Outstanding Securities of any series entitled to join
in the giving or making of (i) any Notice of Default, (ii) any declaration of
acceleration referred to in Section 502, (iii) any request to institute
proceedings referred to in Section 507(2) or (iv) any direction referred to in
Section 512, in each case with respect to Securities of such series. If any
record date is set pursuant to this paragraph, the Holders of Outstanding
Securities of such series on such record date, and no other Holders, shall be
entitled to join in such notice, declaration, request or direction or to revoke
the same, whether or not such Holders remain Holders after such record date;
provided that no such action shall be effective hereunder unless taken on or
prior to the applicable Expiration Date by Holders of the requisite principal
amount of Outstanding Securities of such series on such record date. Nothing in
this paragraph shall be construed to prevent the Trustee from setting a new
record date for any action for which a record date has previously been set
pursuant to this paragraph (whereupon the record date previously set shall
automatically and with no action by any Person be canceled and of no effect),
and nothing in this paragraph shall be construed to render ineffective any
action taken by Holders of the requisite principal amount of Outstanding
Securities of the relevant series on the date such action is taken. Promptly
after any record date is set pursuant to this paragraph, the Trustee, at the
Corporation's expense, shall cause notice of such record date, the proposed
action by Holders and the applicable Expiration Date to be sent to the
Corporation in writing and to each Holder of Securities of the relevant series
in the manner set forth in Section 106.

         With respect to any record date set pursuant to this Section, the party
hereto which sets such record date may designate any day as the "Expiration
Date" and from time to time may change the Expiration Date to any earlier or
later day; provided that no such change shall be effective unless notice of the
proposed new Expiration Date is given to the other party hereto in writing, and
to each Holder of Securities of the relevant series in the manner set forth in
Section 106, on or prior to the existing Expiration Date. If an Expiration Date
is not designated with respect to any record date set pursuant to this Section,
the party hereto which set such record date shall be deemed to have initially
designated the 180th day after such record date as the Expiration Date with
respect thereto, subject to its right to change the Expiration Date as provided
in this paragraph. Notwithstanding the foregoing, no Expiration Date shall be
later than the 180th day after the applicable record date.

         Without limiting the foregoing, a Holder entitled hereunder to take any
action hereunder with regard to any particular Security may do so with regard to
all or any part of the principal

                                       10
<PAGE>   17

amount of such Security or by one or more duly appointed agents each of which
may do so pursuant to such appointment with regard to all or any part of such
principal amount.

SECTION 105. NOTICES, ETC., TO TRUSTEE AND CORPORATION.

         Any request, demand, authorization, direction, notice, consent, waiver
or Act of Holders or other document provided or permitted by this Indenture to
be made upon, given or furnished to, or filed with,

                  (1) the Trustee by any Holder or by the Corporation shall be
         sufficient for every purpose hereunder if made, given, furnished or
         filed in writing (which may be made via facsimile) to or with the
         Trustee at its Corporate Trust Office, Attention: Corporate Trust
         Administration, or

                  (2) the Corporation by the Trustee or by any Holder shall be
         sufficient for every purpose hereunder (unless otherwise herein
         expressly provided) if in writing and mailed, first-class postage
         prepaid, to the Corporation addressed to it at the address of its
         principal office specified in the first paragraph of this instrument,
         Attention: Treasurer, or at any other address previously furnished in
         writing to the Trustee by the Corporation.

SECTION 106. NOTICE TO HOLDERS; WAIVER.

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

         In case by reason of the suspension of regular mail service or by
reason of any other cause it shall be impracticable to give such notice by mail,
then such notification as shall be made with the approval of the Trustee shall
constitute a sufficient notification for every purpose hereunder.

SECTION 107. CONFLICT WITH TRUST INDENTURE ACT.

         If any provision hereof limits, qualifies or conflicts with a provision
of the Trust Indenture Act which is required under such Act to be a part of and
govern this Indenture, the latter provision shall control. If any provision of
this Indenture modifies or excludes any

                                       11
<PAGE>   18

provision of the Trust Indenture Act which may be so modified or excluded, the
latter provision shall be deemed to apply to this Indenture as so modified or to
be excluded, as the case may be.

SECTION 108. EFFECT OF HEADINGS AND TABLE OF CONTENTS.

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

SECTION 109. SUCCESSORS AND ASSIGNS.

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

SECTION 110. SEPARABILITY CLAUSE.

         In case any provision in this Indenture or in the Securities 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.

SECTION 111. BENEFITS OF INDENTURE.

         Unless otherwise specified pursuant to Section 301 with respect to the
Securities of any series, nothing in this Indenture or in the Securities,
express or implied, shall give to any Person, other than the parties hereto,
their successors hereunder and the Holders, any benefit or any legal or
equitable right, remedy or claim under this Indenture.

SECTION 112. GOVERNING LAW.

         This Indenture and the Securities shall be governed by and construed in
accordance with the laws of the State of New York, without regard to conflicts
of laws principles thereof.

SECTION 113. LEGAL HOLIDAYS.

         Unless otherwise specified pursuant to Section 301 with respect to the
Securities of any series, in any case where any Interest Payment Date,
Redemption Date or Stated Maturity of any Security shall not be a Business Day,
then (notwithstanding any other provision of this Indenture or of the Securities
(other than a provision of any Security which specifically states that such
provision shall apply in lieu of this Section)) payment of interest or principal
(and premium, if any) need not be made on such date, but may be made on the next
succeeding Business Day, unless that Business Day is in a different calendar
year, in which case the payment will be made on the preceding Business Day, in
each case, with the same force and effect as if made on the Interest Payment
Date or Redemption Date, or at the Stated Maturity.

SECTION 114. NO SECURITY INTEREST CREATED.

                                       12
<PAGE>   19

         Nothing in this Indenture or in the Securities expressed or implied,
shall be construed to constitute a security interest under the Uniform
Commercial Code or similar legislation, as now or hereafter enacted and in
effect in any jurisdiction where property of the Corporation or its subsidiaries
is located.

         which the principal of or any premium or interest on such Securities as
         to which such election is made shall be payable, the periods within
         which and the terms and conditions upon which such election is to be
         made and the amount so payable (or the manner in which such amount
         shall be determined);

                  (14) if other than the entire principal amount thereof, the
         portion of the principal amount of any Securities of the series which
         shall be payable upon declaration of acceleration of the Maturity
         thereof pursuant to Section 502;

                  (15) if the principal amount payable at the Stated Maturity of
         any Securities of the series will not be determinable as of any one or
         more dates prior to the Stated Maturity, the amount which shall be
         deemed to be the principal amount of such Securities as of any such
         date for any purpose thereunder or hereunder, including the principal
         amount thereof which shall be due and payable upon any Maturity other
         than the Stated Maturity or which shall be deemed to be Outstanding as
         of any date prior to the Stated Maturity (or, in any such case, the
         manner in which such amount deemed to be the principal amount shall be
         determined);

                  (16) if either or both of Sections 1302 and 1303 do not apply
         to any Securities of the series;

                  (17) if applicable, that any Securities of the series shall be
         issuable in whole or in part in the form of one or more Global
         Securities and, in such case, the respective Depositary or Depositaries
         for such Global Securities, the form of any legend or legends which
         shall be borne by any such Global Security in addition to or in lieu of
         that set forth in Section 204 and any circumstances in addition to or
         in lieu of those set forth in Clause (2) of the last paragraph of
         Section 305 in which any such Global Security may be exchanged in whole
         or in part for Securities registered, and any transfer of such Global
         Security in whole or in part may be registered, in the name or names of
         Persons other than the Depositary for such Global Security or a nominee
         thereof;

                  (18) any addition, modification or deletion of any Events of
         Default or covenants provided with respect to any Securities of the
         series and any change in the right of the Trustee or the requisite
         Holders of such Securities to declare the principal amount thereof due
         and payable pursuant to Section 502;

                  (19) any addition to or change in the covenants set forth in
         Article Ten which applies to Securities of the series;

                  (20) the subordination of the Securities of such series to any
         other indebtedness of the Corporation, including, without limitation,
         the Securities of any other series; and

                  (21) any other terms of the series.

                                       22
<PAGE>   29

         All Securities of any one series shall be substantially identical
except as to denomination and except as may otherwise be provided in or pursuant
to the Board Resolution referred to above and (subject to Section 303) set
forth, or determined in the manner provided, in the Officer's Certificate
referred to above or in any such indenture supplemental hereto.

         If any of the terms of the series are established by action taken
pursuant to a Board Resolution, a copy of an appropriate record of such action
shall be certified by the Secretary or an Assistant Secretary of the Corporation
and delivered to the Trustee at or prior to the delivery of the Officer's
Certificate setting forth the terms or the manner of determining the terms of
the series.

         With respect to Securities of a series offered in a Periodic Offering,
the Board Resolution (or action taken pursuant thereto), Officer's Certificate
or supplemental indenture referred to above may provide general terms or
parameters for Securities of such series and provide either that the specific
terms of particular Securities of such series shall be specified in a Company
Order or that such terms shall be determined by the Corporation in accordance
with other procedures specified in a Company Order as contemplated by the third
paragraph of Section 303.

         Notwithstanding Section 301(2) herein and unless otherwise expressly
provided with respect to a series of Securities, the aggregate principal amount
of a series of Securities may be increased and additional Securities of such
series may be issued up to the maximum aggregate principal amount authorized
with respect to such series as increased.

SECTION 302. DENOMINATIONS.

         The Securities of each series shall be issuable only in fully
registered form without coupons and only in such denominations as shall be
specified as contemplated by Section 301. In the absence of any such specified
denomination with respect to the Securities of any series, the Securities of
such series shall be issuable in denominations of $1,000 and any integral
multiple thereof.

SECTION 303. EXECUTION, AUTHENTICATION, DELIVERY AND DATING.

         The Securities shall be executed on behalf of the Corporation by its
Chairman of the Board, its Chief Executive Officer, its President, a Vice
President or the Treasurer and attested by its Secretary or one of its Assistant
Secretaries. The signature of any of these officers on the Securities may be
manual or facsimile.

         Securities bearing the manual or facsimile signatures of individuals
who were at any time the proper officers of the Corporation shall bind the
Corporation, notwithstanding that such individuals or any of them have ceased to
hold such offices prior to the authentication and delivery of such Securities or
did not hold such offices at the date of such Securities.

         At any time and from time to time after the execution and delivery of
this Indenture, the Corporation may deliver Securities of any series executed by
the Corporation to the Trustee for

                                       23
<PAGE>   30

authentication, together with a Company Order for the authentication and
delivery of such Securities, and the Trustee in accordance with the Company
Order shall authenticate and deliver such Securities, provided, however, that in
the case of Securities offered in a Periodic Offering, the Trustee shall
authenticate and deliver such Securities from time to time in accordance with
such other procedures (including, without limitation, the receipt by the Trustee
of oral or electronic instructions from the Corporation or its duly authorized
agents, promptly confirmed in writing) acceptable to the Trustee as may be
specified by or pursuant to a Company Order delivered to the Trustee prior to
the time of the first authentication of Securities of such series. If the form
or terms of the Securities of the series have been established by or pursuant to
one or more Board Resolutions as permitted by Sections 201 and 301, in
authenticating such Securities, and accepting the additional responsibilities
under this Indenture in relation to such Securities, the Trustee shall be
entitled to receive, and (subject to Section 601) shall be fully protected in
relying upon, an Opinion of Counsel stating,

                  (1) if the form of such Securities has been established by or
         pursuant to Board Resolution as permitted by Section 201, that such
         form has been established in conformity with the provisions of this
         Indenture;

                  (2) if the terms of such Securities have been, or in the case
         of Securities of a series offered in a Periodic Offering, will be,
         established by or pursuant to Board Resolution as permitted by Section
         301, that such terms have been, or in the case of Securities of a
         series offered in a Periodic Offering, will be, established in
         conformity with the provisions of this Indenture, subject, in the case
         of Securities of a series offered in a Periodic Offering, to any
         conditions specified in such Opinion of Counsel; and

                  (3) that such Securities, when issued and executed by the
         Corporation and when authenticated and delivered by the Trustee in the
         manner and subject to any conditions specified in such Opinion of
         Counsel, will constitute valid and legally binding obligations of the
         Corporation enforceable in accordance with their terms, subject to
         bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium
         and similar laws of general applicability relating to or affecting
         creditors' rights and to general equity principles.

         If such form or terms have been so established, the Trustee shall not
be required to authenticate such Securities if the issue of such Securities
pursuant to this Indenture will affect the Trustee's own rights, duties or
immunities under the Securities and this Indenture or otherwise in a manner
which is not reasonably acceptable to the Trustee.

         Notwithstanding the provisions of Section 301 and of the preceding
paragraph, if all Securities of a series are not to be originally issued at one
time, it shall not be necessary to deliver the Officer's Certificate otherwise
required pursuant to Section 301 or the Company Order and Opinion of Counsel
otherwise required pursuant to such preceding paragraph at or prior to the
authentication of each Security of such series if such documents are delivered
at or prior to the authentication upon original issuance of the first Security
of such series to be issued.

                                       24
<PAGE>   31

         With respect to Securities of a series offered in a Periodic Offering,
the Trustee may rely, as to the authorization by the Corporation of any of such
Securities, the form and terms thereof and the legality, validity, binding
effect and enforceability thereof, upon the Opinion of Counsel and the other
documents delivered pursuant to Sections 201 and 301 and this Section, as
applicable, in connection with the first authentication of Securities of such
series.

         Each Security shall be dated the date of its authentication.

         No Security shall be entitled to any benefit under this Indenture or be
valid or obligatory for any purpose unless there appears on such Security a
certificate of authentication substantially in the form provided for herein
executed by the Trustee by manual signature of an authorized officer, and such
certificate upon any Security shall be conclusive evidence, and the only
evidence, that such Security has been duly authenticated and delivered
hereunder. Notwithstanding the foregoing, if any Security shall have been
authenticated and delivered hereunder but never issued and sold by the
Corporation, and the Corporation shall deliver such Security to the Trustee for
cancellation as provided in Section 309, for all purposes of this Indenture such
Security shall be deemed never to have been authenticated and delivered
hereunder and shall never be entitled to the benefits of this Indenture.

SECTION 304. TEMPORARY SECURITIES.

         Pending the preparation of definitive Securities of any series, the
Corporation may execute, and upon Company Order the Trustee shall authenticate
and deliver, temporary Securities which are printed, lithographed, typewritten,
mimeographed or otherwise produced, in any authorized denomination,
substantially of the tenor of the definitive Securities in lieu of which they
are issued and with such appropriate insertions, omissions, substitutions and
other variations as the officers executing such Securities may determine, as
evidenced by their execution of such Securities.

         If temporary Securities of any series are issued, the Corporation will
cause definitive Securities of that series to be prepared without unreasonable
delay. After the preparation of definitive Securities of such series, the
temporary Securities of such series shall be exchangeable for definitive
Securities of such series upon surrender of the temporary Securities of such
series at the office or agency of the Corporation in a Place of Payment for that
series, without charge to the Holder. Upon surrender for cancellation of any one
or more temporary Securities of any series, the Corporation shall execute and
the Trustee shall authenticate and deliver in exchange therefor one or more
definitive Securities of the same series, of any authorized denominations and of
like tenor and aggregate principal amount. Until so exchanged, the temporary
Securities of any series shall in all respects be entitled to the same benefits
under this Indenture as definitive Securities of such series and tenor.

SECTION 305. REGISTRATION, REGISTRATION OF TRANSFER AND EXCHANGE.

         The Corporation shall cause to be kept at the Corporate Trust Office of
the Trustee a register (the register maintained in such office or in any other
office or agency of the Corporation

                                       25
<PAGE>   32

in a Place of Payment being herein sometimes referred to as the "Security
Register") in which, subject to such reasonable regulations as it may prescribe,
the Corporation shall provide for the registration of Securities and of
transfers of Securities. The Trustee is hereby appointed "Security Registrar"
for the purpose of registering Securities and transfers of Securities as herein
provided.

         Upon surrender for registration of transfer of any Security of a series
at the office or agency of the Corporation in a Place of Payment for that
series, the Corporation shall execute, and the Trustee shall authenticate and
deliver, in the name of the designated transferee or transferees, one or more
new Securities of the same series, of any authorized denominations and of like
tenor and aggregate principal amount.

         At the option of the Holder, Securities of any series may be exchanged
for other Securities of the same series, of any authorized denominations and of
like tenor and aggregate principal amount, upon surrender of the Securities to
be exchanged at such office or agency. Whenever any Securities are so
surrendered for exchange, the Corporation shall execute, and the Trustee shall
authenticate and deliver, the Securities which the Holder making the exchange is
entitled to receive.

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

         Every Security presented or surrendered for registration of transfer or
for exchange shall (if so required by the Corporation or the Trustee) be duly
endorsed, or be accompanied by a written instrument of transfer in form
satisfactory to the Corporation and the Security Registrar duly executed, by the
Holder thereof or his attorney duly authorized in writing.

         No service charge shall be made for any registration of transfer or
exchange of Securities, but the Corporation may require payment of a sum
sufficient to cover any tax or other governmental charge that may be imposed in
connection with any registration of transfer or exchange of Securities, other
than exchanges pursuant to Section 304, 906 or 1106 not involving any transfer.

         If the Securities of any series (or of any series and specified tenor)
are to be redeemed, the Corporation shall not be required (A) to issue, register
the transfer of or exchange any Securities of that series (or of that series and
specified tenor, as the case may be) during a period beginning at the opening of
business 15 days before the day of the mailing of a notice of redemption of any
such Securities selected for redemption and ending at the close of business on
the day of such mailing, or (B) to register the transfer of or exchange any
Security so selected for redemption in whole or in part, except the unredeemed
portion of any Security being redeemed in part.

         The provisions of Clauses (1), (2), (3) and (4) below shall apply only
to Global Securities:

                                       26
<PAGE>   33

                  (1) Each Global Security authenticated under this Indenture
         shall be registered in the name of the Depositary designated for such
         Global Security or a nominee thereof and delivered to such Depositary
         or a nominee thereof or custodian therefor, and each such Global
         Security shall constitute a single Security for all purposes of this
         Indenture.

                  (2) Notwithstanding any other provision in this Indenture, no
         Global Security may be exchanged in whole or in part for Securities
         registered, and no transfer of a Global Security in whole or in part
         may be registered, in the name of any Person other than the Depositary
         for such Global Security or a nominee thereof unless (A) such
         Depositary has notified the Corporation that it is unwilling or unable
         to continue as Depositary for such Global Security and a successor
         Depositary has not been appointed by the Corporation within 90 days of
         receipt by the Corporation of such notification, (B) if at any time the
         Depositary ceases to be a clearing agency registered under the Exchange
         Act at a time when the Depositary is required to be so registered to
         act as such Depositary and no successor Depositary shall have been
         appointed by the Corporation within 90 days after it became aware of
         such cessation, or (C) there shall exist such circumstances, if any, in
         addition to or in lieu of the foregoing as have been specified for this
         purpose as contemplated by Section 301. Notwithstanding the foregoing,
         the Corporation may at any time in its sole discretion determine that
         Securities issued in the form of a Global Security shall no longer be
         represented in whole or in part by such Global Security, and the
         Trustee, upon receipt of a Company Order therefor, shall authenticate
         and deliver definitive Securities in exchange in whole or in part for
         such Global Security.

                  (3) Subject to Clause (2) above, any exchange or transfer of a
         Global Security for other Securities may be made in whole or in part,
         and all Securities issued in exchange for or upon transfer of a Global
         Security or any portion thereof shall be registered in such names as
         the Depositary for such Global Security shall direct.

                  (4) Every Security authenticated and delivered upon
         registration of transfer of, or in exchange for or in lieu of, a Global
         Security or any portion thereof, whether pursuant to this Section,
         Section 304, 306, 906 or 1106 or otherwise, shall be authenticated and
         delivered in the form of, and shall be, a Global Security, unless such
         Security is registered in the name of a Person other than the
         Depositary for such Global Security or a nominee thereof.

SECTION 306.      MUTILATED, DESTROYED, LOST AND STOLEN SECURITIES.

         If any mutilated Security is surrendered to the Trustee, the
Corporation shall execute and the Trustee shall authenticate and deliver in
exchange therefor a new Security of the same series and of like tenor and
principal amount and bearing a number not contemporaneously outstanding.

         If there shall be delivered to the Corporation and the Trustee (i)
evidence to their satisfaction of the destruction, loss or theft of any Security
and (ii) such security or indemnity as may be required by them to save each of
them and any agent of either of them harmless, then, in

                                       27
<PAGE>   34

the absence of notice to the Corporation or the Trustee that such Security has
been acquired by a bona fide purchaser, the Corporation shall execute and the
Trustee shall authenticate and deliver, in lieu of any such destroyed, lost or
stolen Security, a new Security of the same series and of like tenor and
principal amount and bearing a number not contemporaneously outstanding.

         In case any such mutilated, destroyed, lost or stolen Security has
become or is about to become due and payable, the Corporation in its discretion
may, instead of issuing a new Security, pay such Security.

         Upon the issuance of any new Security under this Section, the
Corporation may require the payment of a sum sufficient to cover any tax, fee,
assessment or other governmental charge that may be imposed in relation thereto
and any other expenses (including the fees and expenses of the Trustee and its
agents and counsel) connected therewith.

         Every new Security of any series issued pursuant to this Section in
lieu of any destroyed, lost or stolen Security shall constitute an original
additional contractual obligation of the Corporation, whether or not the
destroyed, lost or stolen Security shall be at any time enforceable by anyone,
and shall be entitled to all the benefits of this Indenture equally and
proportionately with any and all other Securities of that series duly issued
hereunder.

         The provisions of this Section are exclusive and shall preclude (to the
extent lawful) all other rights and remedies with respect to the replacement or
payment of mutilated, destroyed, lost or stolen Securities.

SECTION 307.      PAYMENT OF INTEREST; INTEREST RIGHTS PRESERVED.

         Except as otherwise provided as contemplated by Section 301 with
respect to any series of Securities, interest on any Security which is payable,
and is punctually paid or duly provided for, on any Interest Payment Date shall
be paid to the Person in whose name that Security (or one or more Predecessor
Securities) is registered at the close of business on the Regular Record Date
for such interest.

         Except as otherwise provided as contemplated by Section 301 with
respect to any series of Securities, any interest on any Security of any series
which is payable, but is not punctually paid or duly provided for, on any
Interest Payment Date (herein called "Defaulted Interest") shall forthwith cease
to be payable to the Holder on the relevant Regular Record Date by virtue of
having been such Holder, and such Defaulted Interest may be paid by the
Corporation, at its election in each case, as provided in Clause (1) or (2)
below:

                  (1) The Corporation may elect to make payment of any Defaulted
         Interest to the Persons in whose names the Securities of such series
         (or their respective Predecessor Securities) are registered at the
         close of business on a Special Record Date for the payment of such
         Defaulted Interest, which shall be fixed in the following manner. The
         Corporation shall notify the Trustee in writing of the amount of
         Defaulted Interest proposed to be paid on each Security of such series
         and the date of the proposed payment,

                                       28
<PAGE>   35
         and at the same time the Corporation shall deposit with the Trustee an
         amount of money equal to the aggregate amount proposed to be paid in
         respect of such Defaulted Interest or shall make arrangements
         satisfactory to the Trustee for such deposit prior to the date of the
         proposed payment, such money when deposited to be held in trust for the
         benefit of the Persons entitled to such Defaulted Interest as in this
         Clause provided. Thereupon the Trustee shall fix a Special Record Date
         for the payment of such Defaulted Interest which shall be not more than
         15 days and not less than 10 days prior to the date of the proposed
         payment and not less than 10 days after the receipt by the Trustee of
         the notice of the proposed payment. The Trustee shall promptly notify
         the Corporation of such Special Record Date and, in the name and at the
         expense of the Corporation, shall cause notice of the proposed payment
         of such Defaulted Interest and the Special Record Date therefor to be
         given to each Holder of Securities of such series in the manner set
         forth in Section 106, not less than 10 days prior to such Special
         Record Date. Notice of the proposed payment of such Defaulted Interest
         and the Special Record Date therefor having been so mailed, such
         Defaulted Interest shall be paid to the Persons in whose names the
         Securities of such series (or their respective Predecessor Securities)
         are registered at the close of business on such Special Record Date and
         shall no longer be payable pursuant to the following Clause (2).

                  (2) The Corporation may make payment of any Defaulted Interest
         on the Securities of any series in any other lawful manner not
         inconsistent with the requirements of any securities exchange, if any,
         on which such Securities may be listed, and upon such notice as may be
         required by such exchange, if, after notice given by the Corporation to
         the Trustee of the proposed payment pursuant to this Clause, such
         manner of payment shall be deemed practicable by the Trustee.

         Subject to the foregoing provisions of this Section, each Security
delivered under this Indenture upon registration of transfer of or in exchange
for or in lieu of any other Security shall carry the rights to interest accrued
and unpaid, and to accrue, which were carried by such other Security.

SECTION 308.      PERSONS DEEMED OWNERS.

         Prior to due presentment of a Security for registration of transfer,
the Corporation, the Trustee and any agent of the Corporation or the Trustee may
treat the Person in whose name such Security is registered as the owner of such
Security for the purpose of receiving payment of principal of and any premium
and (subject to Section 307) any interest on such Security and for all other
purposes whatsoever, whether or not such Security be overdue, and neither the
Corporation, the Trustee nor any agent of the Corporation or the Trustee shall
be affected by notice to the contrary.

         None of the Company, the Trustee, any Paying Agent or the Security
Registrar will have any responsibility or liability for any aspect of the
records relating to or payments made on

                                       29
<PAGE>   36

account of beneficial ownership interest of a Global Security or for
maintaining, supervising or reviewing any records relating to such beneficial
ownership interests.

         Notwithstanding the foregoing, with respect to any Global Security,
nothing herein shall prevent the Company, the Trustee, or any Agent of the
Company or the Trustee, from giving effect to any written certification, proxy
or other authorization furnished by any depositary, as a Holder, with respect to
such Global Security or impair, as between such depositary and owners of
beneficial interests in such Global Security, the operation of customary
practices governing the exercise of the rights of such depositary as Holder of
such Global Security.

SECTION 309.      CANCELLATION.

         All Securities surrendered for payment, redemption, registration of
transfer or exchange or for credit against any sinking fund payment shall, if
surrendered to any Person other than the Trustee, be delivered to the Trustee
and shall be promptly canceled by it. The Corporation may at any time deliver to
the Trustee for cancellation any Securities previously authenticated and
delivered hereunder which the Corporation may have acquired in any manner
whatsoever, and may deliver to the Trustee (or to any other Person for delivery
to the Trustee) for cancellation any Securities previously authenticated
hereunder which the Corporation has not issued and sold, and all Securities so
delivered shall be promptly canceled by the Trustee. No Securities shall be
authenticated in lieu of or in exchange for any Securities canceled as provided
in this Section, except as expressly permitted by this Indenture. All canceled
Securities held by the Trustee shall be disposed of in its customary manner or
as directed by a Company Order; provided, however, that the Trustee shall not be
required to destroy such canceled Securities.

SECTION 310.      COMPUTATION OF INTEREST.

         Except as otherwise specified as contemplated by Section 301 for
Securities of any series, interest on the Securities of each series shall be
computed on the basis of a 360-day year of twelve 30-day months.

SECTION 311.      CUSIP NUMBERS.

         The Corporation in issuing the Securities may use "CUSIP" numbers (if
then generally in use), and, if so, the Trustee shall use "CUSIP" numbers in
notices of redemption as a convenience to Holders; provided that any such notice
may state that no representation is made as to the correctness of such numbers
either as printed on the Securities or as contained in any notice of a
redemption and that reliance may be placed only on the other identification

the Corporation, shall execute proper instruments acknowledging satisfaction and
discharge of this Indenture, when

                  (1) either

                           (A) all Securities theretofore authenticated and
                  delivered (other than (i) Securities which have been

                  repaid to the Corporation or discharged from such trust, as
                  provided in Section 1003) have been delivered to the Trustee
                  for cancellation; or

                  the Trustee for cancellation

                                    (i) have become due and payable, or

                           one year under arrangements satisfactory to the
                           Trustee for the giving of notice of redemption by the
                           Trustee in the name, and at the expense, of the
                           Corporation,

                  and the Corporation, in the case of (i), (ii) or (iii) above,
                  has deposited or caused to be deposited with the Trustee as
                  trust funds in trust for the purpose (i) money in an amount,
                  (ii) Government Obligations (as defined in Section 1304) which
                  through the scheduled payment of principal and interest in
                  respect thereof in accordance with their terms will provide,
                  not later than the due date of any payment, money in an
                  amount, or (iii) a combination thereof, sufficient, in the
                  case of (ii) or (iii), in the opinion of a nationally
                  recognized firm of independent public accountants expressed in
                  a written certification thereof delivered to the Trustee, to
                  pay and discharge, and which shall be applied by the Trustee
                  to pay and discharge, the entire indebtedness on such
                  Securities not theretofore delivered to the Trustee for
                  cancellation, for principal and any premium and interest to
                  the

                                       31
<PAGE>   38

                  date of such deposit (in the case of Securities which have
                  become due and payable) or to the Stated Maturity or
                  Redemption Date, as the case may be;

                  (2) the Corporation has paid or caused to be paid all other
         sums payable hereunder by the Corporation; and

         precedent herein provided for relating to the satisfaction and
         discharge of this Indenture have been complied with.

         Notwithstanding the satisfaction and discharge of this Indenture, the
obligations of the Corporation to the Trustee under Section 607, the obligations
of the Corporation to any Authenticating Agent under Section 614 and, if money
shall have been deposited with the Trustee pursuant to subclause (B) of Clause
(1) of this Section, the obligations of the Trustee under Section 402 and the
last paragraph of Section 1003 shall survive such satisfaction and discharge.

SECTION 402.      APPLICATION OF TRUST MONEY.

         Subject to the provisions of the last paragraph of Section 1003, all
money deposited with the Trustee pursuant to Section 401 shall be held in trust

Indenture, to the payment, either directly or through any Paying Agent
(including the Corporation acting as its own Paying Agent) as the Trustee may
determine, to the Persons entitled thereto, of the principal and any premium and
interest for whose payment such money has been deposited with the Trustee.

                                    REMEDIES

SECTION 501.      EVENTS OF DEFAULT.

         "Event of Default," wherever used herein with respect to Securities of
any series, means any one of the following events (whatever the reason for such
Event of Default and whether it shall be voluntary or involuntary or be effected
by operation of law or pursuant to any judgment, decree or order of any court or
any order, rule or regulation of any administrative or governmental body),
unless it is inapplicable to a particular series or is specifically deleted or
modified in the Board Resolution (or action taken pursuant thereto), Officer's
Certificate or supplemental indenture under which such series of Securities is
issued or has been deleted or modified in an indenture supplemental hereto:

                  (1) default in the payment of any interest upon any Security
         of that series when it becomes due and payable, and continuance of such
         default for a period of 30 days; provided, however, that if the
         Corporation is permitted by the terms of the Securities of such series
         to defer the payment in question, the date on which such payment is due
         and payable shall be the date on which the Corporation is required to

                                       32
<PAGE>   39

         make payment following such deferral, if such deferral has been elected
         pursuant to the terms of the Securities; or

                  (2) default in the payment of the principal of or any premium
         on any Security of that series at its Maturity; or

                  (3) default in the making of any sinking fund payment, when
         and as due by the terms of a Security of that series, and continuance
         of such default for a period of 60 days; or

                  (4) default in the performance, or breach, of any covenant of
         the Corporation in this Indenture (other than a covenant a default in
         whose performance or whose breach is elsewhere in this Section
         specifically dealt with or which has expressly been included in this
         Indenture solely for the benefit of series of Securities other than
         that series), and continuance of such default or breach for a period of
         90 days after there has been given, by registered or certified mail, to
         the Corporation by the Trustee or to the Corporation and the Trustee by
         the Holders of at least 25% in principal amount of the Outstanding
         Securities of that series a written notice specifying such default or
         breach and requiring it to be remedied and stating that such notice is
         a "Notice of Default" hereunder, unless the Trustee, or the Trustee and
         the Holders of a principal amount of Securities of such series not less
         than the principal amount of Securities the Holders of which gave such
         notice, as the case may be, shall agree in writing to an extension of
         such period prior to its expiration; provided, however, that the
         Trustee, or the Trustee and the Holders of such principal amount of
         Securities of such series, as the case may be, shall be deemed to have
         agreed to an extension of such period if corrective action is initiated
         by the Corporation within such period and is being diligently pursued;
         or

                  (5) the entry by a court having jurisdiction in the premises
         of (A) a decree or order for relief in respect of the Corporation in an
         involuntary case or proceeding under any applicable federal or state
         bankruptcy, insolvency, reorganization or other similar law or (B) a
         decree or order adjudging the Corporation a bankrupt or insolvent, or
         approving as properly filed a petition seeking reorganization,
         arrangement, adjustment or composition of or in respect of the
         Corporation under any applicable federal or state law, or appointing a
         custodian, receiver, liquidator, assignee, trustee, sequestrator or
         other similar official of the Corporation or of any substantial part of
         its property, or ordering the winding-up or liquidation of its affairs,
         and the continuance of any such decree or order for relief or any such
         other decree or order unstayed and in effect for a period of 90
         consecutive days; or

                  (6) the commencement by the Corporation of a voluntary case or
         proceeding under any applicable federal or state bankruptcy,
         insolvency, reorganization or other similar law or of any other case or
         proceeding to be adjudicated a bankrupt or insolvent, or the consent by
         it to the entry of a decree or order for relief in respect of the
         Corporation in an involuntary case or proceeding under any applicable
         federal or state bankruptcy,

                                       33
<PAGE>   40

         insolvency, reorganization or other similar law or to the commencement
         of any bankruptcy or insolvency case or proceeding against it, or the
         filing by it of a petition or answer or consent seeking reorganization
         or relief under any applicable federal or state law, or the consent by
         it to the filing of such petition or to the appointment of or taking
         possession by a custodian, receiver, liquidator, assignee, trustee,
         sequestrator or other similar official of the Corporation or of any
         substantial part of its property, or the making by it of an assignment
         for the benefit of creditors, or the admission by it in writing of its
         inability to pay its debts generally as they become due, or the
         authorization of any such action by the Board of Directors; or

                  (7) any other Event of Default provided with respect to
         Securities of that series.

SECTION 502.      ACCELERATION OF MATURITY; RESCISSION AND ANNULMENT.

         If an Event of Default with respect to Securities of any series at the
time Outstanding occurs and is continuing, then in every such case the Trustee
or the Holders of not less than 25% in principal amount of the Outstanding
Securities of that series may declare the principal amount of all the Securities
of that series (or, if any Securities of that series are Original Issue Discount
Securities, such portion of the principal amount of such Securities as may be
specified by the terms thereof) to be due and payable immediately, by a notice
in writing to the Corporation (and to the Trustee if given by Holders), and upon
any such declaration such principal amount (or specified amount) shall become
immediately due and payable.

         At any time after such a declaration of acceleration with respect to
Securities of any series has been made and before a judgment or decree for
payment of the money due has been obtained by the Trustee as hereinafter in this
Article provided, the Holders of a majority in principal amount of the
Outstanding Securities of such series, by written notice to the Corporation and
the Trustee, may rescind and annul such declaration and its consequences if

                  (1) the Corporation has paid or deposited with the Trustee a
         sum sufficient to pay

                          (A) all overdue interest on all Securities of that
                  series,

                          (B) the principal of (and premium, if any, on) any
                  Securities of that series which have become due otherwise than
                  by such declaration of acceleration and any interest thereon
                  at the rate or rates prescribed therefor in such Securities,

                          (C) to the extent that payment of such interest is
                  lawful, interest upon overdue interest at the rate or rates
                  prescribed therefor in such Securities, and

                                       34
<PAGE>   41
                           (D) all sums paid or advanced by the Trustee
                  hereunder and the reasonable compensation, expenses,
                  disbursements and advances of the Trustee, its agents and
                  counsel;

         and

                  (2) all Events of Default with respect to Securities of that
         series, other than the non-payment of the principal of Securities of
         that series which have become due solely by such declaration of
         acceleration, have been cured or waived as provided in Section 513.

                  No such rescission shall affect any subsequent default or
         impair any right consequent thereon.

SECTION 503.      COLLECTION OF INDEBTEDNESS AND SUITS FOR ENFORCEMENT
                  BY TRUSTEE.

         The Corporation covenants that if

                  (1) default is made in the payment of any interest on any
         Security when such interest becomes due and payable and such default
         continues for a period of 30 days, or

                  (2) default is made in the payment of the principal of (or
         premium, if any, on) any Security at the Maturity thereof,

the Corporation will, upon demand of the Trustee, pay to it, for the benefit of
the Holders of such Securities, the whole amount then due and payable on such
Securities for principal and any premium and interest and, to the extent that
payment of such interest shall be legally enforceable, interest on any overdue
principal and premium and on any overdue interest, at the rate or rates
prescribed therefor in such Securities, and, in addition thereto, such further
amount as shall be sufficient to cover the costs and expenses of collection,
including the reasonable compensation, expenses, disbursements and advances of
the Trustee, its agents and counsel.

         If the Corporation fails to pay such amounts forthwith upon such
demand, the Trustee, in its own name and as trustee of an express trust, may
institute a judicial proceeding for the collection of the sums so due and
unpaid, and may prosecute such proceeding to judgment or final decree, and may
enforce the same against the Corporation or any other obligor upon such
Securities and collect the moneys adjudged or decreed to be payable in the
manner provided by law out of the property of the Corporation or any other
obligor upon such Securities, wherever situated.

         If an Event of Default with respect to Securities of any series occurs
and is continuing, the Trustee may in its discretion proceed to protect and
enforce its rights and the rights of the Holders of Securities of such series by
such appropriate judicial proceedings as the Trustee shall deem most effectual
to protect and enforce any such rights, whether for the specific enforcement

                                       35
<PAGE>   42

of any covenant or agreement in this Indenture or in aid of the exercise of any
power granted herein, or to enforce any other proper remedy.

SECTION 504.      TRUSTEE MAY FILE PROOFS OF CLAIM.

         In case of any judicial proceeding relative to the Corporation (or any
other obligor upon the Securities), its property or its creditors, the Trustee
shall be entitled and empowered, by intervention in such proceeding or
otherwise, to take any and all actions authorized under the Trust Indenture Act
in order to have claims of the Holders and the Trustee allowed in any such
proceeding. In particular, the Trustee shall be authorized to collect and
receive any moneys or other property payable or deliverable on any such claims
and to distribute the same; and any custodian, receiver, assignee, trustee,
liquidator, sequestrator or other similar official in any such judicial
proceeding is hereby authorized by each Holder to make such payments to the
Trustee and, in the event that the Trustee shall consent to the making of such
payments directly to the Holders, to pay to the Trustee any amount due it for
the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel, and any other amounts due the Trustee under
Section 607.

         No provision of this Indenture shall be deemed to authorize the Trustee
to authorize or consent to or accept or adopt on behalf of any Holder any plan
of reorganization, arrangement, adjustment or composition affecting the
Securities or the rights of any Holder thereof or to authorize the Trustee to
vote in respect of the claim of any Holder in any such proceeding; provided,
however, that the Trustee may, on behalf of the Holders, vote for the election
of a trustee in bankruptcy or similar official and be a member of a creditors'
or other similar committee.

SECTION 505.      TRUSTEE MAY ENFORCE CLAIMS WITHOUT POSSESSION OF SECURITIES.

         All rights of action and claims under this Indenture or the Securities
may be prosecuted and enforced by the Trustee without the possession of any of
the Securities or the production thereof in any proceeding relating thereto, and
any such proceeding instituted by the Trustee shall be brought in its own name
as trustee of an express trust, and any recovery of judgment shall, after
provision for the payment of the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, be for the
ratable benefit of the Holders of the Securities in respect of which such
judgment has been recovered.

SECTION 506.      APPLICATION OF MONEY COLLECTED.

         Any money collected by the Trustee pursuant to this Article shall be
applied in the following order, at the date or dates fixed by the Trustee and,
in case of the distribution of such money on account of principal or any premium
or interest, upon presentation of the Securities and the notation thereon of the
payment if only partially paid and upon surrender thereof if fully paid:

                  First: To the payment of all amounts due the Trustee under
         Section 607;

                                       36
<PAGE>   43

                  Second: To the payment of the amounts then due and unpaid for
         principal of and any premium and interest on the Securities in respect
         of which or for the benefit of which such money has been collected,
         ratably, without preference or priority of any kind, according to the
         amounts due and payable on such Securities for principal and any
         premium and interest, respectively; and

                  Third: To the payment of the balance, if any, to the
         Corporation.

SECTION 507.      LIMITATION ON SUITS.

         No Holder of any Security of any series shall have any right to
institute any proceeding, judicial or otherwise, with respect to this Indenture,
or for the appointment of a receiver or trustee, or for any other remedy
hereunder, unless

                  (1) such Holder has previously given written notice to the
         Trustee of a continuing Event of Default with respect to the Securities
         of that series;

                  (2) the Holders of not less than 25% in principal amount of
         the Outstanding Securities of all affected series, considered as one
         class, or, in the case of an Event of Default of the character
         specified above in Section 501(1), (2) or (3), that series, shall have
         made written request to the Trustee to institute proceedings in respect
         of such Event of Default in its own name as Trustee hereunder;

                  (3) such Holder or Holders have offered to the Trustee
         reasonable indemnity against the costs, expenses and liabilities to be
         incurred in compliance with such request;

                  (4) the Trustee for 60 days after its receipt of such notice,
         request and offer of indemnity has failed to institute any such
         proceeding; and

                  (5) no direction inconsistent with such written request has
         been given to the Trustee during such 60-day period by the Holders of a
         majority in principal amount of the Outstanding Securities of all
         affected series, considered as one class, or, in the case of an Event
         of Default of the character specified above in Section 501(1), (2) or
         (3), that series,

it being understood and intended that no one or more of such Holders shall have
any right in any manner whatever by virtue of, or by availing of, any provision
of this Indenture to affect, disturb or prejudice the rights of any other of
such Holders, or to obtain or to seek to obtain priority or preference over any
other of such Holders or to enforce any right under this Indenture, except in
the manner herein provided and for the equal and ratable benefit of all of such
Holders.

SECTION 508.      UNCONDITIONAL RIGHT OF HOLDERS TO RECEIVE PRINCIPAL, PREMIUM
                  AND INTEREST.

         Notwithstanding any other provision in this Indenture, the Holder of
any Security shall have the right, which is absolute and unconditional, to
receive payment of the principal of and any premium and (subject to Section 307)
interest on such Security on the respective Stated

                                       37
<PAGE>   44

Maturities expressed in such Security (or, in the case of redemption, on the
Redemption Date) and to institute suit for the enforcement of any such payment,
and such rights shall not be impaired without the consent of such Holder.

SECTION 509.      RESTORATION OF RIGHTS AND REMEDIES.

         If the Trustee or any Holder has instituted any proceeding to enforce
any right or remedy under this Indenture and such proceeding has been
discontinued or abandoned for any reason, or has been determined adversely to
the Trustee or to such Holder, then and in every such case, subject to any
determination in such proceeding, the Corporation, the Trustee and the Holders
shall be restored severally and respectively to their former positions hereunder
and thereafter all rights and remedies of the Trustee and the Holders shall
continue as though no such proceeding had been instituted.

SECTION 510.      RIGHTS AND REMEDIES CUMULATIVE.

         Except as otherwise provided with respect to the replacement or payment
of mutilated, destroyed, lost or stolen Securities in the last paragraph of
Section 306, no right or remedy herein conferred upon or reserved to the Trustee
or to the Holders is intended to be exclusive of any other right or remedy, and
every right and remedy shall, to the extent permitted by law, be cumulative and
in addition to every other right and remedy given hereunder or now or hereafter
existing at law or in equity or otherwise. The assertion or employment of any
right or remedy hereunder, or otherwise, shall not prevent the concurrent
assertion or employment of any other appropriate right or remedy.

SECTION 511.      DELAY OR OMISSION NOT WAIVER.

         No delay or omission of the Trustee or of any Holder of any Securities
to exercise any right or remedy accruing upon any Event of Default shall impair
any such right or remedy or constitute a waiver of any such Event of Default or
an acquiescence therein.

         Every right and remedy given by this Article or by law to the Trustee
or to the Holders may be exercised from time to time, and as often as may be
deemed expedient, by the Trustee or by the Holders, as the case may be.

SECTION 512.      CONTROL BY HOLDERS.

         The Holders of a majority in principal amount of the Outstanding
Securities of any series shall have the right to direct the time, method and
place of conducting any proceeding for any remedy available to the Trustee, or
exercising any trust or power conferred on the Trustee, with respect to the
Securities of such series; provided that

                  (1) such direction shall not be in conflict with any rule of
         law or with this Indenture,

                                       38
<PAGE>   45

                  (2) the Trustee may take any other action deemed proper by the
         Trustee which is not inconsistent with such direction, and

                  (3) subject to the provisions of Section 601, the Trustee
         shall have the right to decline to follow any such direction if the
         Trustee in good faith shall, by a Responsible Officer or Officers of
         the Trustee, determine that the proceeding so directed would involve
         the Trustee in personal liability.

         If an Event of Default is continuing with respect to all Outstanding
Securities, the Holders of a majority in principal amount of all the Outstanding
Securities, considered as one class, shall have the right to make such
direction, and not the Holders of Securities of any one series.

SECTION 513.      WAIVER OF PAST DEFAULTS.

         The Holders of not less than a majority in principal amount of the
Outstanding Securities of all series with respect to which any default under the
Indenture shall have occurred and be continuing (voting as one class) may, on
behalf of the Holders of all Securities of all such series, waive such past
default under the Indenture and its consequences, except a default

                  (1) in the payment of the principal of or any premium or
         interest on any Security of such series, or

                  (2) in respect of a covenant or provision hereof which under
         Article Nine cannot be modified or amended without the consent of the
         Holder of each Outstanding Security of the series affected.

         Upon any such waiver, such default shall cease to exist and be deemed
not to have occurred, and any Event of Default arising therefrom shall be deemed
to have been cured and not to have occurred, for every purpose of this
Indenture; but no such waiver shall extend to any subsequent or other default or
impair any right consequent thereon.

SECTION 514.      UNDERTAKING FOR COSTS.

         In any suit for the enforcement of any right or remedy under this
Indenture, or in any suit against the Trustee for any action taken, suffered or
omitted by it as Trustee, a court may require any party litigant in such suit to
file an undertaking to pay the costs, including legal fees and expenses of such
suit, and may assess costs against any such party litigant, in the manner and to
the extent provided in the Trust Indenture Act; provided that neither this
Section nor the Trust Indenture Act shall be deemed to authorize any court to
require such an undertaking or to make such an assessment in (i) any suit
instituted by the Trustee, (ii) any suit instituted by any Holder, or group of
Holders, holding in the aggregate more than 10% in principal amount of the
Outstanding Securities of any series, or (iii) any suit instituted by any Holder
for the enforcement of the payment of the principal of (or premium, if any) or
interest on any Security on or after the

                                       39
<PAGE>   46

respective Stated Maturities expressed in such Security (or, in the case of
redemption, on or after the Redemption Date).

SECTION 515.      WAIVER OF STAY OR EXTENSION LAWS.

         The Corporation covenants (to the extent that it may lawfully do so)
that it will not at any time insist upon, or plead, or in any manner whatsoever
claim or take the benefit or advantage of, any stay or extension law wherever
enacted, now or at any time hereafter in force, which may affect the covenants
or the performance of this Indenture; and the Corporation (to the extent that it
may lawfully do so) 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.

                                   ARTICLE VI.
                                   THE TRUSTEE

SECTION 601.      CERTAIN DUTIES AND RESPONSIBILITIES.

         The duties and responsibilities of the Trustee shall be as provided in
this Indenture and no duties shall be inferred or implied against the Trustee.
Notwithstanding the foregoing, no provision of this Indenture shall require the
Trustee to expend or risk its own funds or otherwise incur any financial
liability in the performance of any of its duties hereunder, or in the exercise
of any of its rights or powers, if it shall have reasonable grounds for
believing that repayment of such funds or adequate indemnity against such risk
or liability is not reasonably assured to it. Whether or not therein expressly
so provided, every provision of this Indenture relating to the conduct or
affecting the liability of or affording protection to the Trustee shall be
subject to the provisions of this Section.

SECTION 602.      NOTICE OF DEFAULTS.

         If a default occurs hereunder with respect to Securities of any series,
the Trustee shall give the Holders of Securities of such series notice of such
default as and to the extent provided by the Trust Indenture Act; provided,
however, that in the case of any default of the character specified in Section
501(4) with respect to Securities of such series, no such notice to Holders
shall be given until at least 30 days after the occurrence thereof. For the
purpose of this Section, the term "default" means any event which is, or after
notice or lapse of time or both would become, an Event of Default with respect
to Securities of such series.

SECTION 603.      CERTAIN RIGHTS OF TRUSTEE.

         Subject to the provisions of Section 601:

                  (1) the Trustee may conclusively rely and shall be fully
         protected in acting or refraining from acting upon any resolution,
         certificate, statement, instrument, opinion,

                                       40
<PAGE>   47

         report, notice, request, direction, consent, order, bond, debenture,
         note or other paper or document believed by it to be genuine and to
         have been signed or presented by the proper party or parties;

                  (2) any request or direction of the Corporation mentioned
         herein shall be sufficiently evidenced by a Company Request or Company
         Order or as otherwise expressly provided herein, and any resolution of
         the Board of Directors shall be sufficiently evidenced by a Board
         Resolution;

                  (3) whenever in the administration of this Indenture the
         Trustee shall deem it desirable that a matter be proved or established
         prior to taking, suffering or omitting any action hereunder, the
         Trustee (unless other evidence be herein specifically prescribed) may,
         in the absence of bad faith on its part, rely upon an Officer's
         Certificate;

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

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

                  (6) the Trustee shall not be bound to make any investigation
         into the facts or matters stated in any resolution, certificate,
         statement, instrument, opinion, report, notice, request, direction,
         consent, order, bond, debenture, note, other evidence of indebtedness
         or other paper or document, but the Trustee, in its discretion, may
         make such further inquiry or investigation into such facts or matters
         as it may see fit, and, if the Trustee shall determine to make such
         further inquiry or investigation, it shall be entitled, at reasonable
         times previously notified to the Corporation, to examine the relevant
         books, records and premises of the Corporation, personally or by agent
         or attorney at the sole cost of the Corporation and shall incur no
         liability or additional liability of any kind by reason of such inquiry
         or investigation; and

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

SECTION 604.      NOT RESPONSIBLE FOR RECITALS OR ISSUANCE OF SECURITIES.

         The recitals contained herein and in the Securities, except the
Trustee's certificates of authentication, shall be taken as the statements of
the Corporation, and neither the Trustee nor

                                       41
<PAGE>   48

any Authenticating Agent assumes any responsibility for their correctness. The
Trustee makes no representations as to the validity or sufficiency of this
Indenture or of the Securities. Neither the Trustee nor any Authenticating Agent
shall be accountable for the use or application by the Corporation of Securities
or the proceeds thereof.

SECTION 605.      MAY HOLD SECURITIES.

         The Trustee, any Authenticating Agent, any Paying Agent, any Security
Registrar or any other agent of the Corporation, in its individual or any other
capacity, may become the owner or pledgee of Securities and, subject to Sections
608 and 613, may otherwise deal with the Corporation with the same rights it
would have if it were not Trustee, Authenticating Agent, Paying Agent, Security
Registrar or such other agent.

SECTION 606.      MONEY HELD IN TRUST.

         Money held by the Trustee in trust hereunder need not be segregated
from other funds except to the extent required by law. The Trustee shall be
under no liability for interest on any money received by it hereunder except as
otherwise agreed in writing with the Corporation.

SECTION 607.      COMPENSATION AND REIMBURSEMENT.

         The Corporation agrees:

                  (1) to pay to the Trustee from time to time such compensation
         as shall be agreed to in writing between the Corporation and the
         Trustee for all services rendered by it hereunder (which compensation
         shall not be limited by any provision of law in regard to the
         compensation of a trustee of an express trust);

                  (2) except as otherwise expressly provided herein, to
         reimburse the Trustee upon its request for all expenses, disbursements
         and advances incurred or made by the Trustee in accordance with any
         provision of this Indenture (including the reasonable compensation and
         the expenses and disbursements of its agents and counsel), except any
         such expense, disbursement or advance as may be attributable to its
         negligence, willful misconduct or bad faith; and

                  (3) to indemnify the Trustee for, and to hold it harmless
         against, any and all loss, liability, damage, claim or expense,
         including taxes (other than taxes based on the income of the Trustee)
         incurred without negligence, willful misconduct or bad faith on its
         part, arising out of or in connection with the acceptance or
         administration of the trust or trusts hereunder, including the costs
         and expenses of defending itself against any claim whether asserted by
         the Corporation, a Holder or any other Person or liability in
         connection with the exercise or performance of any of its powers or
         duties hereunder.

                                       42
<PAGE>   49

         The Trustee shall have a lien prior to the Securities upon all property
and funds held by it hereunder for any amount owing it or any predecessor
Trustee pursuant to this Section 607, except with respect to funds held in trust
for the benefit of the Holders of particular Securities.

         Without limiting any rights available to the Trustee under applicable
law, when the Trustee incurs expenses or renders services in connection with an
Event of Default specified in Section 501(5) or Section 501(6), the expenses
(including the reasonable charges and expenses of its counsel) and the
compensation for the services are intended to constitute expenses of
administration under any applicable federal or state bankruptcy, insolvency or
other similar law.

         The provisions of this Section shall survive the resignation or removal
of the Trustee and the termination of this Indenture.

SECTION 608.      CONFLICTING INTERESTS.

         If the Trustee has or shall acquire a conflicting interest within the
meaning of the Trust Indenture Act, the Trustee shall either eliminate such
interest or resign, to the extent and in the manner provided by, and subject to
the provisions of, the Trust Indenture Act and this Indenture. To the extent
permitted by such Act, the Trustee shall not be deemed to have a conflicting
interest by virtue of being a trustee under this Indenture with respect to
Securities of more than one series.

SECTION 609.      CORPORATE TRUSTEE REQUIRED; ELIGIBILITY.

         There shall at all times be a Trustee hereunder with respect to the
Securities of each series, which may be Trustee hereunder for Securities of one
or more other series. Each Trustee shall be a Person that is eligible pursuant
to the Trust Indenture Act to act as such and has a combined capital and surplus
of at least $50,000,000. If any such Person publishes reports of condition at
least annually, pursuant to law or to the requirements of its supervising or
examining authority, then for the purposes of this Section and to the extent
permitted by the Trust Indenture Act, the combined capital and surplus of such
Person shall be deemed to be its combined capital and surplus as set forth in
its most recent report of condition so published. If at any time the Trustee
with respect to the Securities of any series shall cease to be eligible in
accordance with the provisions of this Section, it shall resign immediately in
the manner and with the effect hereinafter specified in this Article.

SECTION 610.      RESIGNATION AND REMOVAL; APPOINTMENT OF SUCCESSOR.

         No resignation or removal of the Trustee and no appointment of a
successor Trustee pursuant to this Article shall become effective until the
acceptance of appointment by the successor Trustee in accordance with the
applicable requirements of Section 611.

         The Trustee may resign at any time with respect to the Securities of
one or more series by giving written notice thereof to the Corporation. If the
instrument of acceptance by a successor Trustee required by Section 611 shall
not have been delivered to the Trustee within 30 days after

                                       43
<PAGE>   50

the giving of such notice of resignation, the resigning Trustee may petition, at
the expense of the Corporation, any court of competent jurisdiction for the
appointment of a successor Trustee with respect to the Securities of such
series.

         The Trustee may be removed at any time with respect to the Securities
of any series by Act of the Holders of a majority in principal amount of the
Outstanding Securities of such series, delivered to the Trustee and to the
Corporation. Upon such removal, the Corporation may petition, at its expense,
any court of competent jurisdiction for the appointment of a successor Trustee
with respect to the Securities of such series.

         If at any time:

                  (1) the Trustee shall fail to comply with Section 608 after
         written request therefor by the Corporation or by any Holder who has
         been a bona fide Holder of a Security for at least six months, or

                  (2) the Trustee shall cease to be eligible under Section 609
         and shall fail to resign after written request therefor by the
         Corporation or by any such Holder, or

                  (3) the Trustee shall become incapable of acting or shall be
         adjudged a bankrupt or insolvent or a receiver of the Trustee or of its
         property shall be appointed or any public officer shall take charge or
         control of the Trustee or of its property or affairs for the purpose of
         rehabilitation, conservation or liquidation,

then, in any such case, (A) the Corporation by a Board Resolution may remove the
Trustee with respect to all Securities, or (B) subject to Section 514, any
Holder who has been a bona fide Holder of a Security for at least six months
may, on behalf of himself and all others similarly situated, petition any court
of competent jurisdiction for the removal of the Trustee with respect to all
Securities and the appointment of a successor Trustee or Trustees.

         If the Trustee shall resign, be removed or become incapable of acting,
or if a vacancy shall occur in the office of Trustee for any cause, with respect
to the Securities of one or more series, the Corporation, by a Board Resolution,
shall promptly appoint a successor Trustee or Trustees with respect to the
Securities of that or those series (it being understood that any such successor
Trustee may be appointed with respect to the Securities of one or more or all of
such series and that at any time there shall be only one Trustee with respect to
the Securities of any particular series) and shall comply with the applicable
requirements of Section 611. If, within one year after such resignation, removal
or incapability, or the occurrence of such vacancy, a successor Trustee with
respect to the Securities of any series shall be appointed by Act of the Holders
of a majority in principal amount of the Outstanding Securities of such series
delivered to the Corporation and the retiring Trustee, the successor Trustee so
appointed shall, forthwith upon its acceptance of such appointment in accordance
with the applicable requirements of Section 611, become the successor Trustee
with respect to the Securities of such series and to that extent supersede the
successor Trustee appointed by the Corporation. If no successor Trustee with
respect to the Securities of any series shall have been so appointed by the

                                       44
<PAGE>   51

Corporation or the Holders and accepted appointment in the manner required by
Section 611, any Holder who has been a bona fide Holder of a Security of such
series for at least six months may, on behalf of himself and all others
similarly situated, petition any court of competent jurisdiction for the
appointment of a successor Trustee with respect to the Securities of such
series.

         The Corporation shall give notice of each resignation and each removal
of the Trustee with respect to the Securities of any series and each appointment
of a successor Trustee with respect to the Securities of any series to all
Holders of Securities of such series in the manner provided in Section 106. Each
notice shall include the name of the successor Trustee with respect to the
Securities of such series and the address of its Corporate Trust Office.

SECTION 611.      ACCEPTANCE OF APPOINTMENT BY SUCCESSOR.

         In case of the appointment hereunder of a successor Trustee with
respect to all Securities, every such successor Trustee so appointed shall
execute, acknowledge and deliver to the Corporation and to the retiring Trustee
an instrument accepting such appointment, and thereupon the resignation or
removal of the retiring Trustee shall become effective and such successor
Trustee, without any further act, deed or conveyance, shall become vested with
all the rights, powers, trusts and duties of the retiring Trustee; but, on the
request of the Corporation or the successor Trustee, such retiring Trustee
shall, upon payment of its charges, execute and deliver an instrument
transferring to such successor Trustee all the rights, powers and trusts of the
retiring Trustee and shall duly assign, transfer and deliver to such successor
Trustee all property and money held by such retiring Trustee hereunder.

         In case of the appointment hereunder of a successor Trustee with
respect to the Securities of one or more (but not all) series, the Corporation,
the retiring Trustee and each successor Trustee with respect to the Securities
of one or more series shall execute and deliver an indenture supplemental hereto
wherein each successor Trustee shall accept such appointment and which (1) shall
contain such provisions as shall be necessary or desirable to transfer and
confirm to, and to vest in, each successor Trustee all the rights, powers,
trusts and duties of the retiring Trustee with respect to the Securities of that
or those series to which the appointment of such successor Trustee relates, (2)
if the retiring Trustee is not retiring with respect to all Securities, shall
contain such provisions as shall be deemed necessary or desirable to confirm
that all the rights, powers, trusts and duties of the retiring Trustee with
respect to the Securities of that or those series as to which the retiring
Trustee is not retiring shall continue to be vested in the retiring Trustee, and
(3) shall add to or change any of the provisions of this Indenture as shall be
necessary to provide for or facilitate the administration of the trusts
hereunder by more than one Trustee, it being understood that nothing herein or
in such supplemental indenture shall constitute such Trustees co-trustees of the
same trust and that each such Trustee shall be trustee of a trust or trusts
hereunder separate and apart from any trust or trusts hereunder administered by
any other such Trustee; and upon the execution and delivery of such supplemental
indenture the resignation or removal of the retiring Trustee shall become
effective to the extent provided therein and each such successor Trustee,
without any further act, deed or conveyance, shall become vested with all the
rights, powers, trusts and duties of the retiring Trustee with respect to

                                       45
<PAGE>   52

the Securities of that or those series to which the appointment of such
successor Trustee relates; but, on request of the Corporation or any successor
Trustee, such retiring Trustee shall duly assign, transfer and deliver to such
successor Trustee all property and money held by such retiring Trustee hereunder
with respect to the Securities of that or those series to which the appointment
of such successor Trustee relates.

         Upon request of any such successor Trustee, the Corporation shall
execute any and all instruments for more fully and certainly vesting in and
confirming to such successor Trustee all such rights, powers and trusts referred
to in the first or second preceding paragraph, as the case may be.

         No successor Trustee shall accept its appointment unless at the time of
such acceptance such successor Trustee shall be qualified and eligible under
this Article.

SECTION 612.      MERGER, CONVERSION, CONSOLIDATION OR SUCCESSION TO BUSINESS.

         Any corporation into which the Trustee may be merged or converted or
with which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any
corporation succeeding to all or substantially all the corporate trust business
of the Trustee, shall be the successor of the Trustee hereunder, provided that
such corporation shall be otherwise qualified and eligible under this Article,
without the execution or filing of any paper or any further act on the part of
any of the parties hereto. In case any Securities shall have been authenticated,
but not delivered, by the Trustee then in office, any successor by merger,
conversion or consolidation to such authenticating Trustee may adopt such
authentication and deliver the Securities so authenticated with the same effect
as if such successor Trustee had itself authenticated such Securities.

SECTION 613.      PREFERENTIAL COLLECTION OF CLAIMS AGAINST CORPORATION.

         If and when the Trustee shall be or become a creditor of the
Corporation (or any other obligor upon the Securities), the Trustee shall be
subject to the provisions of the Trust Indenture Act regarding the collection of
claims against the Corporation (or any such other obligor).

SECTION 614.      APPOINTMENT OF AUTHENTICATING AGENT.

         The Trustee may appoint an Authenticating Agent or Agents acceptable to
the Corporation with respect to one or more series of Securities which shall be
authorized to act on behalf of the Trustee to authenticate Securities of such
series issued upon exchange, registration of transfer or partial redemption
thereof or pursuant to Section 306, and Securities so authenticated shall be
entitled to the benefits of this Indenture and shall be valid and obligatory for
all purposes as if authenticated by the Trustee hereunder. Wherever reference is
made in this Indenture to the authentication and delivery of Securities by the
Trustee or the Trustee's certificate of authentication, such reference shall be
deemed to include authentication and delivery on behalf of the Trustee by an
Authenticating Agent and a certificate of authentication executed on behalf of
the Trustee by an Authenticating Agent. Each Authenticating Agent shall

                                       46
<PAGE>   53

be acceptable to the Corporation and shall at all times be a corporation
organized and doing business under the laws of the United States of America, any
State thereof or the District of Columbia, authorized under such laws to act as
Authenticating Agent, having a combined capital and surplus of not less than
$50,000,000 and subject to supervision or examination by federal or state
authority. If such Authenticating Agent publishes reports of condition at least
annually, pursuant to law or to the requirements of said supervising or
examining authority, then for the purposes of this Section, the combined capital
and surplus of such Authenticating Agent shall be deemed to be its combined
capital and surplus as set forth in its most recent report of condition so
published. If at any time an Authenticating Agent shall cease to be eligible in
accordance with the provisions of this Section, such Authenticating Agent shall
resign immediately in the manner and with the effect specified in this Section.

         Any corporation into which an Authenticating Agent may be merged or
converted or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which such Authenticating Agent
shall be a party, or any corporation succeeding to all or substantially all the
corporate agency or corporate trust business of an Authenticating Agent, shall
continue to be an Authenticating Agent, provided that such corporation shall be
otherwise eligible under this Section, without the execution or filing of any
paper or any further act on the part of the Trustee or the Authenticating Agent.

         An Authenticating Agent may resign at any time by giving written notice
thereof to the Trustee and to the Corporation. The Trustee may at any time
terminate the agency of an Authenticating Agent by giving written notice thereof
to such Authenticating Agent and to the Corporation. Upon receiving such a
notice of resignation or upon such a termination, or in case at any time such
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, the Trustee may appoint a successor Authenticating
Agent which shall be acceptable to the Corporation and shall give notice of such
appointment in the manner provided in Section 106 to all Holders of Securities
of the series with respect to which such Authenticating Agent will serve. Any
successor Authenticating Agent upon acceptance of its appointment hereunder
shall become vested with all the rights, powers and duties of its predecessor
hereunder, with like effect as if originally named as an Authenticating Agent.
No successor Authenticating Agent shall be appointed unless eligible under the
provisions of this Section.

         The Corporation agrees to pay to each Authenticating Agent from time to
time reasonable compensation for its services under this Section.

         If an appointment with respect to one or more series is made pursuant
to this Section, the Securities of such series may have endorsed thereon, in
addition to the Trustee's certificate of authentication, an alternative
certificate of authentication in the following form:

                                       47
<PAGE>   54

         This is one of the Securities of the series designated therein referred
to in the within-mentioned Indenture.

addresses of Holders received by the Trustee in its capacity as Security

         The rights of Holders to communicate with other Holders with respect to
their rights under this Indenture or under the Securities, and the corresponding

Indenture Act.

         Every Holder of Securities, by receiving and holding the same, agrees

any disclosure of information as to names and addresses of Holders made pursuant
to the Trust Indenture Act.

SECTION 703.      REPORTS BY TRUSTEE.

         The Trustee shall transmit to Holders such reports concerning the

required by Section 313(a) of the Trust Indenture Act, the Trustee shall, within
60 days after each May 15 following the date of this Indenture, deliver to
Holders a brief report, dated as of such May 15, which complies with the

         A copy of each such report shall, at the time of such transmission to

         The Corporation shall not consolidate with or merge into any other
Person or convey, transfer or lease its properties and assets substantially as
an entirety to any Person, and no Person shall consolidate with or merge into
the Corporation or convey, transfer or lease its properties and assets
substantially as an entirety to the Corporation, unless:

                  (1) in case the Corporation shall consolidate with or merge
         into another Person or convey, transfer or lease its properties and
         assets substantially as an entirety to any Person, the Person formed by
         such consolidation or into which the Corporation is merged or the
         Person which acquires by conveyance or transfer, or which leases, the
         properties and assets of the Corporation substantially as an entirety
         shall be a corporation, partnership, limited liability company or trust
         organized and existing under the laws of the United States of America
         or any State thereof or the District of Columbia and shall expressly
         assume, by an indenture supplemental hereto, executed and delivered to
         the Trustee, in form satisfactory to the Trustee, the due and punctual
         payment of the principal of (and premium, if any) and interest on all
         the Securities and the performance of every covenant of this Indenture
         on the part of the Corporation to be performed or observed;

                  (2) immediately after giving effect to such transaction, no
         Event of Default, and no event which, after notice of lapse of time, or
         both, would become an Event of Default, shall have occurred and be
         continuing;

                  (3) such other conditions as may be specified pursuant to
         Section 301 with respect to the Securities of any series shall have
         been satisfied; and

                  (4) the Corporation shall deliver to the Trustee an Officer's
         Certificate and an Opinion of Counsel, each stating that such
         consolidation, merger, conveyance or transfer and, if a supplemental
         indenture is required in connection with such transaction, such
         supplemental indenture comply with this Article and that all conditions
         precedent herein provided for relating to such transaction have been
         complied with; and the Trustee, subject to Section 601, may rely upon
         such Officer's Certificate and Opinion of Counsel as conclusive
         evidence that such transaction complies with this Section 801.

SECTION 802.      SUCCESSOR SUBSTITUTED.

         Upon any consolidation of the Corporation with, or merger of the
Corporation into, any other Person or any conveyance or transfer of the
properties and assets of the Corporation as an entirety or substantially as an
entirety in accordance with Section 801, the successor Person formed by such
consolidation or into which the Corporation is merged or to which such
conveyance or transfer is made shall succeed to, and be substituted for, and may
exercise every right and power of, the Corporation under this Indenture with the
same effect as if such successor

                                       50
<PAGE>   57

Person had been named as the Corporation herein, and thereafter the predecessor
Person shall be relieved of all obligations and covenants under this Indenture
and the Securities.

         Such successor Person may cause to be signed, and may issue either in
its own name or in the name of the Corporation, any or all of the Securities
issuable hereunder which theretofore shall not have been signed by the
Corporation and delivered to the Trustee; and, upon the order of such successor
Person instead of the Corporation, and subject to all the terms, conditions and
limitations in this Indenture prescribed, the Trustee shall authenticate and
shall deliver any Securities which previously shall have been signed and
delivered by the officers of the Corporation to the Trustee for authentication
pursuant to such provisions and any Securities which such successor Person
thereafter shall cause to be signed and delivered to the Trustee on its behalf
for the purpose pursuant to such provisions. All the Securities so issued shall
in all respects have the same legal rank and benefit under this Indenture as the
Securities theretofore or thereafter issued in accordance with the terms of this
Indenture as though all of such Securities had been issued at the date of the
execution hereof.

         In case of any such consolidation, merger, sale, conveyance or lease,
such changes in phraseology and form may be made in the Securities thereafter to
be issued as may be appropriate.

SECTION 901.      SUPPLEMENTAL INDENTURES WITHOUT CONSENT OF HOLDERS.

         Without the consent of any Holders, the Corporation, when authorized by
a Board Resolution, and the Trustee, at any time and from time to time, may

satisfactory to the Trustee, for any of the following purposes:

                  (1) to evidence the succession of another Person to the
         Corporation and the assumption by any such successor of the covenants
         of the Corporation herein and in the Securities; or

                  (2) to add to the covenants of the Corporation for the benefit
         of the Holders of all or any series of Securities (and if such
         covenants are to be for the benefit of less than all series of
         Securities, stating that such covenants are expressly being included
         solely for the benefit of such series) or to surrender any right or
         power herein conferred upon the Corporation; or

                  (3) to add any additional Events of Default for the benefit of
         the Holders of all or any series of Securities (and if such additional
         Events of Default are to be for the benefit of less than all series of
         Securities, stating that such additional Events of Default are
         expressly being included solely for the benefit of such series); or

                                       51
<PAGE>   58

                  (4) to add to or change any of the provisions of this
         Indenture to such extent as shall be necessary to permit or facilitate
         the issuance of Securities in bearer form, registrable or not
         registrable as to principal, and with or without interest coupons, or
         to facilitate the issuance of Securities in uncertificated form; or

                  (5) to add to, change or eliminate any of the provisions of
         this Indenture in respect of one or more series of Securities; provided
         that any such addition, change or elimination (A) shall neither (i)
         apply to any Security of any series created prior to the execution of
         such supplemental indenture and entitled to the benefit of such
         provision nor (ii) modify the rights of the Holder of any such Security
         with respect to such provision or (B) shall become effective only when
         there is no such Security Outstanding; or

                  (6) to secure the Securities; or

                  (7) to establish the form or terms of Securities of any series
         as permitted by Sections 201 and 301; or

                  (8) to evidence and provide for the acceptance of appointment
         hereunder by a successor Trustee with respect to the Securities of one
         or more series and to add to or change any of the provisions of this
         Indenture as shall be necessary to provide for or facilitate the
         administration of the trusts hereunder by more than one Trustee,
         pursuant to the requirements of Section 611; or

                  (9) to cure any ambiguity, to correct or supplement any
         provision herein which may be defective or inconsistent with any other
         provision herein, or to make any other provisions with respect to
         matters or questions arising under this Indenture; provided that such
         action pursuant to this Clause (9) shall not adversely affect the
         interests of the Holders of Securities of any series in any material
         respect.

SECTION 902.      SUPPLEMENTAL INDENTURES WITH CONSENT OF HOLDERS.

         With the consent of the Holders of not less than a majority in
principal amount of the Outstanding Securities of all series affected by such
supplemental indenture (voting as one class), by Act of said Holders delivered
to the Corporation and the Trustee, the Corporation, when authorized by a Board
Resolution, and the Trustee may enter into an indenture or indentures
supplemental hereto for the purpose of adding any provisions to or changing in
any manner or eliminating any of the provisions of this Indenture or of any
supplemental indenture, or modifying in any manner the rights of the Holders of
Securities under this Indenture; provided, however, that no such supplemental
indenture shall, without the consent of the Holder of each Outstanding Security
affected thereby,

                  (1) change the Stated Maturity of the principal of, or any
         installment of principal of or interest on, any Security (other than
         pursuant to the terms of such Security), or reduce the principal amount
         thereof or the rate of interest thereon or any premium payable upon the
         redemption thereof, or reduce the amount of the principal of

                                       52
<PAGE>   59

         an Original Issue Discount Security or any other Security which would
         be due and payable upon a declaration of acceleration of the Maturity
         thereof pursuant to Section 502 or change the coin or currency in which
         any Security or any premium or interest thereon is payable, or impair
         the right to institute suit for the enforcement of any such payment on
         or after the Stated Maturity thereof (or, in the case of redemption, on
         or after the Redemption Date), or

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

                  (3) modify any of the provisions of this Section, Section 513
         or Section 1006, except to increase any such percentage or to provide
         that certain other provisions of this Indenture cannot be modified or
         waived without the consent of the Holder of each Outstanding Security
         affected thereby; provided, however, that this clause shall not be
         deemed to require the consent of any Holder with respect to changes in
         the references to "the Trustee" and concomitant changes in this Section
         and Section 1006, or the deletion of this proviso, in accordance with
         the requirements of Sections 611 and 901(8).

         A supplemental indenture which changes or eliminates any covenant or
other provision of this Indenture which has expressly been included solely for
the benefit of one or more particular series of Securities, or which modifies
the rights of the Holders of Securities of such series with respect to such
covenant or other provision, shall be deemed not to affect the rights under this
Indenture of the Holders of Securities of any other series.

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

SECTION 903.      EXECUTION OF SUPPLEMENTAL INDENTURES.

         In executing, or accepting the additional trusts created by, any
supplemental indenture permitted by this Article or the modifications thereby of
the trusts created by this Indenture, the Trustee shall be entitled to receive,
and (subject to Section 601) shall be fully protected in relying upon, an
Opinion of Counsel stating that the execution of such supplemental indenture is
authorized or permitted by this Indenture. The Trustee may, but shall not be
obligated to, enter into any such supplemental indenture which affects the
Trustee's own rights, duties or immunities under this Indenture or otherwise.

Indenture for all purposes; and every Holder of Securities theretofore or
thereafter authenticated and delivered hereunder shall be bound thereby.

         Securities of any series authenticated and delivered after the
execution of any supplemental indenture pursuant to this Article may, and shall
if required by the Trustee, bear a notation in form approved by the Trustee as
to any matter provided for in such supplemental indenture. If the Corporation
shall so determine, new Securities of any series so modified as to conform, in
the opinion of the Trustee and the Corporation, to any such supplemental
indenture may be prepared and executed by the Corporation and authenticated and
delivered by the Trustee in exchange for Outstanding Securities of such series.

SECTION 907.  SUBORDINATION UNIMPAIRED.

         This Indenture may not be amended to alter the subordination of any of
the Outstanding Securities without the written consent of each holder of Senior
Indebtedness then outstanding that would be adversely affected thereby.

                                   ARTICLE X.
                                   COVENANTS

SECTION 1001.     PAYMENT OF PRINCIPAL, PREMIUM AND INTEREST.

         The Corporation covenants and agrees for the benefit of each series of
Securities that it will duly and punctually pay the principal of and any premium
and interest on the Securities of that series in accordance with the terms of
the Securities and this Indenture.

SECTION 1002.     MAINTENANCE OF OFFICE OR AGENCY.

         The Corporation will maintain in each Place of Payment for any series
of Securities an office or agency where Securities of that series may be
presented or surrendered for payment, where Securities of that series may be
surrendered for registration of transfer or exchange and where notices and
demands to or upon the Corporation in respect of the Securities of that series
and this Indenture may be served. The Corporation will give prompt written
notice to the Trustee of the location, and any change in the location, of such
office or agency. If at any time the Corporation shall fail to maintain any such
required office or agency or shall fail to furnish the Trustee with the address
thereof, such presentations, surrenders, notices and demands may be made or
served at the Corporate Trust Office of the Trustee, and the Corporation hereby
appoints the Trustee as its agent to receive all such presentations, surrenders,
notices and demands.

<PAGE>   61

         The Corporation may also from time to time designate one or more other
offices or agencies where the Securities of one or more series may be presented
or surrendered for any or all such purposes and may from time to time rescind
such designations; provided, however, that no such designation or rescission
shall in any manner relieve the Corporation of its obligation to maintain an
office or agency in each Place of Payment for Securities of any series for such
purposes. The Corporation will give prompt written notice to the Trustee of any
such designation or rescission and of any change in the location of any such
other office or agency.

SECTION 1003.     MONEY FOR SECURITIES PAYMENTS TO BE HELD IN TRUST.

         If the Corporation 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 or any premium 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 any premium and 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 Corporation shall have one or more Paying Agents for any
series of Securities, it will, on or prior to each due date of the principal of
or any premium or interest on any Securities of that series, deposit with a
Paying Agent a sum sufficient to pay such amount, such sum to be held as
provided by the Trust Indenture Act, and (unless such Paying Agent is the
Trustee) the Corporation will promptly notify the Trustee of its action or
failure so to act.

         The Corporation 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 (1) hold all sums
held by it for the payment of the principal of (and premium, if any) or interest
on Securities 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, (2) give the Trustee notice of any default by the Corporation (or any
other obligor upon the Securities) in the making of any payment of principal
(and premium, if any) or interest, (3) comply with the provisions of the Trust
Indenture Act applicable to it as a Paying Agent and (4) during the continuance
of any default by the Corporation (or any other obligor upon the Securities of
that series) in the making of any payment in respect of the Securities of that
series, upon the written request of the Trustee, forthwith pay to the Trustee
all sums held in trust by such- Paying Agent for payment in respect of the
Securities of that series.

         The Corporation 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 hereunder by the Corporation 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
Corporation 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.

                                       55
<PAGE>   62

         Any money deposited with the Trustee or any Paying Agent, or then held
by the Corporation, in trust for the payment of the principal of or any premium
or interest on any Security of any series and remaining unclaimed for two years
after such principal, premium or interest has become due and payable shall be
paid to the Corporation on Company Request, or (if then held by the Corporation)
shall be discharged from such trust; and the Holder of such Security shall
thereafter, as an unsecured general creditor, look only to the Corporation for
payment thereof, and all liability of the Trustee or such Paying Agent with
respect to such trust money, and all liability of the Corporation as trustee
thereof, shall thereupon cease; provided, however, that the Trustee or such
Paying Agent, before being required to make any such repayment, may at the
expense of the Corporation cause to be published once, in a newspaper published
in the English language, customarily published on each Business Day and of
general circulation in the Borough of Manhattan, The City of 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
Corporation.

SECTION 1004.     CORPORATE EXISTENCE.

         Subject to Article Eight, the Corporation will do or cause to be done
all things necessary to preserve and keep in full force and effect its corporate
existence, rights (charter and statutory) and franchises.

SECTION 1005.     STATEMENT BY OFFICERS AS TO DEFAULT.

         The Corporation will deliver to the Trustee, on or before October 15 of
each calendar year or on or before such other day in each calendar year as the
Corporation and the Trustee may from time to time agree upon, an Officer's
Certificate, stating whether or not to the best knowledge of the signers thereof
the Corporation is in default in the performance and observance of any of the
terms, provisions and conditions of this Indenture (without regard to any period
of grace or requirement of notice provided hereunder) and, if the Corporation
shall be in default, specifying all such defaults and the nature and status
thereof of which they may have knowledge.

SECTION 1006.     WAIVER OF CERTAIN COVENANTS.

         Except as otherwise specified as contemplated by Section 301 for
Securities of such series, the Corporation may, with respect to the Securities
of any series, omit in any particular instance to comply with any term,
provision or condition set forth in any covenant provided pursuant to Section
301(19), 901(2) or 901(7) for the benefit of the Holders of such series if
before the time for such compliance the Holders of not less than a majority in
principal amount of the Outstanding Securities of such series shall, by Act of
such Holders, either waive such compliance in such instance or generally waive
compliance with such term, provision or condition, but no such waiver shall
extend to or affect such term, provision or condition except to the extent so
expressly waived, and, until such waiver shall become effective, the obligations
of the Corporation and the duties of the Trustee in respect of any such term,
provision or condition shall remain in full force and effect.

         Securities of any series which are redeemable before their Stated
Maturity shall be redeemable in accordance with their terms and (except as
otherwise specified as contemplated by Section 301 for such Securities) in
accordance with this Article.

SECTION 1102.     ELECTION TO REDEEM; NOTICE TO TRUSTEE.

         The election of the Corporation to redeem any Securities shall be
evidenced by a Board Resolution or in another manner specified as contemplated
by Section 301 for such Securities. In case of any redemption at the election of
the Corporation, the Corporation shall, at least 45 days prior to the Redemption
Date fixed by the Corporation (unless a shorter notice shall be satisfactory to
the Trustee), notify the Trustee of such Redemption Date, of the principal
amount of Securities of such series to be redeemed and, if applicable, of the
tenor of the Securities to be redeemed. In the case of any redemption of
Securities (A) prior to the expiration of any restriction on such redemption
provided in the terms of such Securities or elsewhere in this Indenture, or (B)
pursuant to an election of the Corporation which is subject to a condition
specified in the terms of such Securities or elsewhere in this Indenture, the
Corporation shall furnish the Trustee with an Officer's Certificate evidencing
compliance with such restriction or condition.

SECTION 1103.     SELECTION BY TRUSTEE OF SECURITIES TO BE REDEEMED.

         If less than all the Securities of any series are to be redeemed
(unless all the Securities of such series and of a specified tenor are to be
redeemed or unless such redemption affects only a single Security), the
particular Securities to be redeemed shall be selected not more than 60 days
prior to the Redemption Date by the Trustee, from the Outstanding Securities of
such series not previously called for redemption, by such method as the Trustee
shall deem fair and appropriate

                                       57
<PAGE>   64

and which may provide for the selection for redemption of a portion of the
principal amount of any Security of such series; provided that the unredeemed
portion of the principal amount of any Security shall be in an authorized
denomination (which shall not be less than the minimum authorized denomination)
for such Security. If less than all the Securities of such series and of a
specified tenor are to be redeemed (unless such redemption affects only a single
Security), the particular Securities to be redeemed shall be selected not more
than 60 days prior to the Redemption Date by the Trustee, from the Outstanding
Securities of such series and specified tenor not previously called for
redemption in accordance with the preceding sentence.

         The Trustee shall promptly notify the Corporation in writing of the
Securities selected for redemption as aforesaid and, in the case of any
Securities selected for partial redemption as aforesaid, the principal amount
thereof to be redeemed.

         The provisions of the two preceding paragraphs shall not apply with
respect to any redemption affecting only a single Security, whether such
Security is to be redeemed in whole or in part. In the case of any such
redemption in part, the unredeemed portion of the principal amount of the
Security shall be in an authorized denomination (which shall not be less than
the minimum authorized denomination) for such Security.

         For all purposes of this Indenture, unless the context otherwise
requires, all provisions relating to the redemption of Securities shall relate,
in the case of any Securities redeemed or to be redeemed only in part, to the
portion of the principal amount of such Securities which has been or is to be
redeemed.

SECTION 1104.     NOTICE OF REDEMPTION.

         Notice of redemption shall be given by first-class mail, postage
prepaid, mailed not less than 30 nor more than 60 days prior to the Redemption
Date, to each Holder of Securities to be redeemed, at his address appearing in
the Security Register.

         All notices of redemption shall identify the Securities to be redeemed
(including CUSIP number(s)) and shall state:

                           (1) the Redemption Date;

                           (2) the Redemption Price;

                           (3) if less than all the Outstanding Securities of
                  any series and of a specified tenor consisting of more than a
                  single Security are to be redeemed, the identification (and,
                  in the case of partial redemption of any such Securities, the
                  principal amounts) of the particular Securities to be redeemed
                  and, if less than all the Outstanding Securities of any series
                  and of a specified tenor consisting of a single Security are
                  to be redeemed, the principal amount of the particular
                  Security to be redeemed;

                                       58
<PAGE>   65

                           (4) that on the Redemption Date the Redemption Price,
                  together with accrued interest, if any, to the Redemption
                  Date, will become due and payable upon each such Security to
                  be redeemed and, if applicable, that interest thereon will
                  cease to accrue on and after said date;

                           (5) the place or places where each such Security is
                  to be surrendered for payment of the Redemption Price and
                  accrued interest, if any, unless it shall have been specified
                  as contemplated by Section 301 with respect to such Securities
                  that such surrender shall not be required;

                           (6) that the redemption is for a sinking fund, if
                  such is the case; and

                           (7) such other matters as the Corporation shall deem
                  desirable or appropriate.

         Unless otherwise specified with respect to any Securities in accordance
with Section 301, with respect to any redemption of Securities at the election
of the Corporation, unless, upon the giving of notice of such redemption,
Defeasance shall have been effected with respect to such Securities pursuant to
Section 1302, such notice may state that such redemption shall be conditional
upon the receipt by the Trustee or the Paying Agent(s) for such Securities, on
or prior to the date fixed for such redemption, of money sufficient to pay the
principal of and any premium and interest on such Securities and that if such
money shall not have been so received such notice shall be of no force or effect
and the Corporation shall not be required to redeem such Securities. In the
event that such notice of redemption contains such a condition and such money is
not so received, the redemption shall not be made and within a reasonable time
thereafter notice shall be given, in the manner in which the notice of
redemption was given, that such money was not so received and such redemption
was not required to be made, and the Trustee or Paying Agent(s) for the
Securities otherwise to have been redeemed shall promptly return to the Holders
thereof any of such Securities which had been surrendered for payment upon such
redemption.

         Notice of redemption of Securities to be redeemed at the election of
the Corporation, and any notice of non-satisfaction of redemption as aforesaid,
shall be given by the Corporation or, at the Corporation's request, by the
Trustee in the name and at the expense of the Corporation. Subject to the
preceding paragraph, any such notice of redemption shall be irrevocable.

SECTION 1105.     DEPOSIT OF REDEMPTION PRICE.

         On or prior to the Redemption Date specified in the notice of
redemption given as provided in Section 1104, the Corporation will deposit with
the Trustee or with one or more Paying Agents (or if the Corporation is acting
as its own Paying Agent, the Corporation will segregate and hold in trust as
provided in Section 1003) an amount of money sufficient to pay the Redemption
Price of; and any accrued interest on, all the Securities which are to be
redeemed on that date.

                                       59
<PAGE>   66
SECTION 1106.     SECURITIES PAYABLE ON REDEMPTION DATE.

         Notice of redemption having been given as aforesaid, and the
conditions, if any, set forth in such notice having been satisfied, the
Securities or portions thereof so to be redeemed shall, on the Redemption Date,
become due and payable at the Redemption Price therein specified, and from and
after such date (unless, in the case of an unconditional notice of redemption,
the Corporation shall default in the payment of the Redemption Price and accrued
interest, if any) such Securities or portions thereof, if interest-bearing,
shall cease to bear interest. Upon surrender of any such Security for redemption
in accordance with said notice, such Security or portion thereof shall be paid
by the Corporation at the Redemption Price, together with accrued interest, if
any, to the Redemption Date; provided, however, that no such surrender shall be
a condition to such payment if so specified as contemplated by Section 301 with
respect to such Security, and provided further that, unless otherwise specified
as contemplated by Section 301, installments of interest whose Stated Maturity
is on or prior to the Redemption Date will be payable to the Holders of such
Securities, or one or more Predecessor Securities, registered as such at the
close of business on the relevant Record Dates according to their terms and the
provisions of Section 307.

         If any Security called for redemption shall not be so paid upon
surrender thereof for redemption, the principal and any premium shall, until
paid, bear interest from the Redemption Date at the rate prescribed therefor in
the Security.

SECTION 1107.     SECURITIES REDEEMED IN PART.

         Any Security which is to be redeemed only in part shall be surrendered
at a Place of Payment therefor (with, if the Corporation or the Trustee so
requires, due endorsement by, or a written instrument of transfer in form
satisfactory to the Corporation and the Trustee duly executed by, the Holder
thereof or his attorney duly authorized in writing), and the Corporation shall
execute, and the Trustee shall authenticate and deliver to the Holder of such
Security without service charge, a new Security or Securities of the same series
and of like tenor, of any authorized denomination as requested by such Holder,
in aggregate principal amount equal to and in exchange for the unredeemed
portion of the principal of the Security so surrendered.

                                  ARTICLE XII.
                                  SINKING FUNDS

SECTION 1201.     APPLICABILITY OF ARTICLE.

         The provisions of this Article shall be applicable to any sinking fund
for the retirement of Securities of any series except as otherwise specified as
contemplated by Section 301 for such Securities.

         The minimum amount of any sinking fund payment provided for by the
terms of any Securities is herein referred to as a "mandatory sinking fund
payment," and any payment in excess of such minimum amount provided for by the
terms of such Securities is herein referred to

                                       60
<PAGE>   67

as an "optional sinking fund payment." If provided for by the terms of any
Securities, the cash amount of any sinking fund payment may be subject to
reduction as provided in Section 1202. Each sinking fund payment shall be
applied to the redemption of Securities as provided for by the terms of such
Securities.

SECTION 1202.     SATISFACTION OF SINKING FUND PAYMENTS WITH SECURITIES.

         The Corporation (1) may deliver Outstanding Securities of a series
(other than any previously called for redemption) and (2) may apply as a credit
Securities of a series which have been redeemed either at the election of the
Corporation pursuant to the terms of such Securities or through the application
of permitted optional sinking fund payments pursuant to the terms of such
Securities, in each case in satisfaction of all or any part of any sinking fund
payment with respect to any Securities of such series required to be made
pursuant to the terms of such Securities as and to the extent provided for by
the terms of such Securities; provided that the Securities to be so credited
have not been previously so credited. The Securities to be so credited shall be
received and credited for such purpose by the Trustee at the Redemption Price,
as specified in the Securities so to be redeemed, for redemption through
operation of the sinking fund and the amount of such sinking fund payment shall
be reduced accordingly.

SECTION 1203.     REDEMPTION OF SECURITIES FOR SINKING FUND.

         Not less than 45 days prior to each sinking fund payment date for any
Securities, the Corporation will deliver to the Trustee an Officer's Certificate
specifying the amount of the next ensuing sinking fund payment for such
Securities pursuant to the terms of such Securities, the portion thereof, if
any, which is to be satisfied by payment of cash and the portion thereof, if
any, which is to be satisfied by delivering and crediting Securities pursuant to
Section 1202 and stating the basis for such credit and that such Securities have
not been previously so credited and will also deliver to the Trustee any
Securities to be so delivered. Not less than 30 days prior to each such sinking
fund payment date, the Trustee shall select the Securities to be redeemed upon
such sinking fund payment date in the manner specified in Section 1103 and cause
notice of the redemption thereof to be given in the name of and at the expense
of the Corporation in the manner provided in Section 1104. Such notice having
been duly given, the redemption of such Securities shall be made upon the terms
and in the manner stated in Sections 1105 and 1106.

                                 ARTICLE XIII.
                       DEFEASANCE AND COVENANT DEFEASANCE

SECTION 1301.     APPLICABILITY OF ARTICLE.

         Unless, pursuant to Section 301, provision is made that either or both
of (A) defeasance of any Securities or any series of Securities under Section
1302 and (B) covenant defeasance of any Securities or any series of Securities
under Section 1303 shall not apply to such Securities of a series, then the
provisions of either or both of Sections 1302 and Section 1303, as the case may
be, together with Sections 1304 and 1305, shall be applicable to the Outstanding
Securities of such series upon compliance with the conditions set forth below in
this Article.

                                       61
<PAGE>   68

SECTION 1302.     DEFEASANCE AND DISCHARGE.

         The Corporation may cause itself to be discharged from its obligations
with respect to any Securities or any series of Securities on and after the date
the conditions set forth in Section 1304 are satisfied (hereinafter called
"Defeasance"). For this purpose, such Defeasance means that the Corporation
shall be deemed to have paid and discharged the entire indebtedness represented
by such Securities and to have satisfied all its other obligations under such
Securities and this Indenture insofar as such Securities are concerned (and the
Trustee, at the expense of the Corporation, shall execute proper instruments
acknowledging the same), subject to the following which shall survive until
otherwise terminated or discharged hereunder: (1) the rights of Holders of such
Securities to receive, solely from the trust fund described in Section 1304 and
as more fully set forth in such Section, payments in respect of the principal of
and any premium and interest on such Securities when payments are due, (2) the
Corporation's obligations with respect to such Securities under Sections 304,
305, 306, 1002 and 1003 and with respect to the Trustee under Section 607, (3)
the rights, powers, trusts, duties and immunities of the Trustee hereunder and
(4) this Article. Subject to compliance with this Article, Defeasance with
respect to any Securities or any series of Securities by the Corporation is
permitted under this Section 1302 notwithstanding the prior exercise by the
Corporation of its rights under Section 1303 with respect to such Securities.
Following a Defeasance, payment of such Securities may not be accelerated
because of an Event of Default.

SECTION 1303.     COVENANT DEFEASANCE.

         The Corporation may cause itself to be released from its obligations
under any covenants provided pursuant to Section 301(19), 901(2), 901(6) or
901(7) with respect to any Securities or any series of Securities for the
benefit of the Holders of such Securities and the occurrence of any event
specified in Sections 501(4) (with respect to any such covenants provided
pursuant to Section 301(19), 901(2), 901(6) or 901(7)) or 501(7) shall be deemed
not to be or result in an Event of Default with respect to such Securities as
provided in this Section, in each case on and after the date the conditions set
forth in Section 1304 are satisfied (hereinafter called "Covenant Defeasance").
For this purpose, such Covenant Defeasance means that, with respect to such
Securities, the Corporation may omit to comply with and shall have no liability
in respect of any term, condition or limitation set forth in any such specified
Section (to the extent so specified in the case of Section 501(4)), whether
directly or indirectly by reason of any reference elsewhere herein to any such
Section or by reason of any reference in any such Section to any other provision
herein or in any other document, but the remainder of this Indenture and such
Securities shall be unaffected thereby.

SECTION 1304.     CONDITIONS TO DEFEASANCE OR COVENANT DEFEASANCE.

         The following shall be the conditions to the application of Section
1302 or Section 1303 to any Securities or any series of Securities, as the case
may be:

                  (1) The Corporation shall irrevocably have deposited or caused
         to be deposited with the Trustee as trust funds in trust for the
         purpose of making the following

                                       62
<PAGE>   69

         payments, specifically pledged as security for, and dedicated solely
         to, the benefit of the Holders of such Securities, (A) money in an
         amount, or (B) Government Obligations which through the scheduled
         payment of principal and interest in respect thereof in accordance with
         their terms will provide, not later than the due date of any payment,
         money in an amount, or (C) a combination thereof, sufficient, in the
         case of (B) or (C), in the opinion of a nationally recognized firm of
         independent public accountants expressed in a written certification
         thereof delivered to the Trustee, to pay and discharge, and which shall
         be applied by the Trustee to pay and discharge, the principal of and
         any premium and interest on such Securities on the respective Stated
         Maturities or on any Redemption Date established pursuant to Clause (3)
         below, in accordance with the terms of this Indenture and such
         Securities. As used herein, "Government Obligation" means (x) any
         security which is (i) a direct obligation of the United States of
         America or the government which issued the foreign currency in which
         such Securities are payable, for the payment of which its full faith
         and credit is pledged or (ii) an obligation of a Person controlled or
         supervised by and acting as an agency or instrumentality of the United
         States of America or such government which issued the foreign currency
         in which such Securities are payable, the payment of which is
         unconditionally guaranteed as a full faith and credit obligation by the
         United States of America or such other government, which, in either
         case (i) or (ii), is not callable or redeemable at the option of the
         issuer thereof, and (y) any depositary receipt issued by a bank (as
         defined in Section 3(a)(2) of the Securities Act) as custodian with
         respect to any Government Obligation which is specified in clause (x)
         above and held by such bank for the account of the holder of such
         depositary receipt, or with respect to any specific payment of
         principal of or interest on any Government Obligation which is so
         specified and held, provided that (except as required by law) such
         custodian is not authorized to make any deduction from the amount
         payable to the holder of such depositary receipt from any amount
         received by the custodian in respect of the Government Obligation or
         the specific payment of principal or interest evidenced by such
         depositary receipt.

                  (2) No event which is, or after notice or lapse of time or
         both would become, an Event of Default with respect to such Securities
         or any other Securities shall have occurred and be continuing at the
         time of such deposit or, with regard to any such event specified in
         Sections 501(5) and (6), at any time on or prior to the 90th day after
         the date of such deposit (it being understood that this condition shall
         not be deemed satisfied until after such 90th day).

                  (3) If the Securities are to be redeemed prior to Stated
         Maturity (other than from mandatory sinking fund payments or analogous
         payments), notice of such redemption shall have been duly given
         pursuant to this Indenture or provision therefor satisfactory to the
         Trustee shall have been made.

                  (4) The Corporation shall have delivered to the Trustee an
         Officer's Certificate and an Opinion of Counsel, each stating that all
         conditions precedent with respect to such Defeasance or Covenant
         Defeasance have been complied with.

SECTION 1305.     DEPOSITED MONEY AND GOVERNMENT OBLIGATIONS TO BE HELD IN
                  TRUST; MISCELLANEOUS PROVISIONS.

         Subject to the provisions of the last paragraph of Section 1003, all
money and Government Obligations (including the proceeds thereof) deposited with
the Trustee pursuant to Section 1304 in respect of any Securities shall be held
in trust and applied by the Trustee, in accordance with the provisions of such
Securities and this Indenture, to the payment, either directly or through any
such Paying Agent (including the Corporation acting as its own Paying Agent) as
the Trustee may determine, to the Holders of such Securities, of all sums due
and to become due thereon in respect of principal and any premium and interest,
but money so held in trust need not be segregated from other funds except to the
extent required by law.

         The Corporation shall pay and indemnify the Trustee against any tax,
fee or other charge imposed on or assessed against the Government Obligations
deposited pursuant to Section 1304 or the principal and interest received in
respect thereof other than any such tax, fee or other charge which by law is for
the account of the Holders of Outstanding Securities.

         Anything in this Article to the contrary notwithstanding, the Trustee
shall deliver or pay to the Corporation from time to time upon Company Request
any money or Government Obligations held by it as provided in Section 1304 with
respect to any Securities which, in the opinion of a nationally recognized firm
of independent public accountants expressed in a written certification thereof
delivered to the Trustee, are in excess of the amount thereof which would then
be required to be deposited to effect the Defeasance or Covenant Defeasance, as
the case may be, with respect to such Securities.

                                  ARTICLE XIV.
                                  SUBORDINATION

SECTION 1401.     SECURITIES SUBORDINATED TO SENIOR INDEBTEDNESS.

         Except as otherwise specified as contemplated by Section 301 for any
series of Securities, the Corporation covenants and agrees, and each Holder of a
Security, by his acceptance thereof, likewise covenants and agrees, that the
indebtedness represented by the Securities of any series and the payment of the
principal of and any premium or interest on each and all of the Securities of
each series is subordinate, to the extent and in the manner hereinafter set
forth, in right of payment to the prior payment in full of all Senior
Indebtedness. Senior Indebtedness shall continue to be Senior Indebtedness and
entitled to the benefits of these subordination provisions irrespective of any
amendment, modification or waiver of any term of the Senior Indebtedness or
extension or renewal of the Senior Indebtedness.

         In the event (a) of any payment by, or distribution of assets of, the
Corporation of any kind or character, whether in cash, property or securities,
to creditors upon any dissolution, winding-up, liquidation or reorganization of
the Corporation, whether voluntary or involuntary or in bankruptcy, insolvency,
receivership or other proceedings, or (b) subject to the provisions of Section
1402 that (i) a default shall have occurred and be continuing with respect to
the payment

                                       64
<PAGE>   71

of principal, interest or any other monetary amounts due and payable on any
Senior Indebtedness and such default shall have continued beyond the period of
grace, if any, specified in the instrument evidencing such Senior Indebtedness
(and the Trustee shall have received written notice thereof from the Corporation
or one or more holders of Senior Indebtedness or their representative or
representatives or the trustee or trustees under any indenture pursuant to which
any such Senior Indebtedness may have been issued), or (ii) the maturity of any
Senior Indebtedness shall have been accelerated because of a default in respect
of such Senior Indebtedness (and the Trustee shall have received written notice
thereof from the Corporation or one or more holders of Senior Indebtedness or
their representative or representatives or the trustee or trustees under any
indenture pursuant to which any such Senior Indebtedness may have been issued),
then:

         (a) the holders of all Senior Indebtedness shall first be entitled to
receive, in the case of (a) above, payment of all amounts due or to become due
upon all Senior Indebtedness (including interest after the commencement of any
bankruptcy proceeding at the rate specified in the applicable Senior
Indebtedness) and, in the case of subclauses (i) and of clause (b) above,
payment of all amounts due thereon, or provision shall be made for such payment
in money or money's worth, before the Holders of any of the Securities are
entitled to receive any payment on account of the principal of or any premium or
interest on the indebtedness evidenced by the Securities, including, without
limitation, any payments made pursuant to Article Eleven or Article Twelve;

         (b) any payment by, or distribution of assets of, the Corporation of
any kind or character, whether in cash, property or securities, to which the
Holders of any of the Securities would be entitled except for the provisions of
this Article, including any such payment or distribution which may be payable or
deliverable by reason of the payment of any other indebtedness of the
Corporation being subordinated to the payment of such Securities, shall be paid
or delivered by the Person making such payment or distribution, whether a
trustee in bankruptcy, a receiver or liquidating trustee or otherwise, directly
to the holders of such Senior Indebtedness or their representative or
representatives or to the trustee or trustees under any indenture under which
any instruments evidencing any of such Senior Indebtedness may have been issued,
ratably according to the aggregate amounts remaining unpaid on account of such
Senior Indebtedness held or represented by each, to the extent necessary to make
payment in full of all Senior Indebtedness remaining unpaid after giving effect
to any concurrent payment or distribution (or provision therefor) to the holders
of such Senior Indebtedness, before any payment or distribution is made to the
Holders of the indebtedness evidenced by such Securities;

         (c) in the event that, notwithstanding the foregoing, any payment by,
or distribution of assets of, the Corporation of any kind or character, whether
in cash, property or securities, including any such payment or distribution
which may be payable or deliverable by reason of the payment of any other
indebtedness of the Corporation being subordinated to the payment of such
Securities, in respect of principal of or any premium or interest on any of the
Securities or in connection with the repurchase by the Corporation of any of the
Securities, shall be received by the Trustee or the Holders of any of the
Securities when such payment or distribution is

                                       65
<PAGE>   72

prohibited pursuant to this Section, such payment or distribution shall be paid
over to the holders of such Senior Indebtedness or their representative or
representatives or to the trustee or trustees under any indenture pursuant to
which any instruments evidencing any such Senior Indebtedness may have been
issued, ratably as aforesaid, for application to the payment of all Senior
Indebtedness remaining unpaid until all such Senior Indebtedness shall have been
paid in full, after giving effect to any concurrent payment or distribution (or
provision therefor) to the holders of such Senior Indebtedness; and

         (d) the Corporation also may not make any payment upon or in respect of
the Securities if (i) a default in the payment of the principal of, premium, if
any, or interest on Senior Indebtedness occurs and is continuing beyond any
applicable period of grace or (ii) any other default occurs and is continuing
with respect to Designated Senior Indebtedness that currently, or with the
passage of time or giving of notice, permits holders of the Designated Senior
Indebtedness as to which such default relates to accelerate its maturity and, in
the case of any such default described in this clause (ii), the Trustee receives
a notice of such default of the type referred to in this clause (ii) (a "Payment
Blockage Notice") from the Corporation or the holders of any Designated Senior
Indebtedness. Payments on the Securities may and shall be resumed (a) in the
case of a payment default, upon the date on which such default is cured or
waived in writing by the holders of the applicable Senior Indebtedness and (b)
in case of a nonpayment default, the earlier of the date on which such
nonpayment default is cured or waived in writing by the holders of Designated
Senior Indebtedness or 179 days after the date on which the applicable Payment
Blockage Notice is received by the Trustee, unless the maturity of any
Designated Senior Indebtedness has been accelerated. No new period of payment
blockage may be commenced under clause (ii) above unless and until (i) 360 days
have elapsed since the effectiveness of the immediately prior Payment Blockage
Notice and (ii) all scheduled payments of principal of, premium, if any, and
interest on the Securities that have come due have been paid in full in cash. No
nonpayment default that existed or was continuing on the date of delivery of any
Payment Blockage Notice to the Trustee shall be, or be made, the basis for a
subsequent Payment Blockage Notice unless such default shall have been waived in
writing or cured for a period of not less than 180 days. If the Corporation
makes any payment to the Trustee or any Holder of any Securities prohibited by
the foregoing, such payment will be required to be held in trust for and paid
over to the holders of Senior Indebtedness (or the representatives thereof).

         Notwithstanding the foregoing, at any time after the 90th day following
the date of deposit of money or Government Obligations pursuant to Section 1304
(provided all other conditions set out in such Section shall have been
satisfied) the funds so deposited and any interest thereon will not be subject
to any rights of holders of Senior Indebtedness including, without limitation,
those arising under this Article.

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

                                       66
<PAGE>   73

provided that (i) the indebtedness or guarantee of indebtedness, as the case may
be, that constitutes Senior Indebtedness is assumed by the Person, if any,
resulting from any such reorganization or readjustment, and (ii) the rights of
the holders of the Senior Indebtedness are not, without the consent of each such
holder adversely affected thereby, altered by such reorganization or
readjustment. The consolidation of the Corporation with, or the merger of the
Corporation into, another Person or the liquidation or dissolution of the
Corporation following the conveyance or transfer of its property as an entirety,
or substantially as an entirety, to another Person upon the terms and conditions
provided for in Article Eight hereof shall not be deemed a dissolution,
winding-up, liquidation or reorganization for the purposes of this Section if
such other Person shall, as part of such consolidation, merger, conveyance or
transfer, comply with the conditions stated in Article Eight hereof.

SECTION 1402.     DISPUTES WITH HOLDERS OF CERTAIN SENIOR INDEBTEDNESS.

         Any failure by the Corporation to make any payment on or perform any
other obligation under Senior Indebtedness, other than any indebtedness incurred
by the Corporation or assumed or guaranteed, directly or indirectly, by the
Corporation for money borrowed (or any deferral, renewal, extension or refunding
thereof) or any indebtedness or obligation as to which the provisions of this
Section shall have been waived by the Corporation in the instrument or
instruments by which the Corporation incurred, assumed, guaranteed or otherwise
created such indebtedness or obligation, shall not be deemed a default or event
of default under Section 1401(b) if (i) the Corporation shall be disputing its
obligation to make such payment or perform such obligation and (ii) either (A)
no final judgment relating to such dispute shall have been issued against the
Corporation which is in full force and effect and is not subject to further
review, including a judgment that has become final by reason of the expiration
of the time within which a party may seek further appeal or review, and (B) in
the event of a judgment that is subject to further review or appeal has been
issued, the Corporation shall in good faith be prosecuting an appeal or other
proceeding for review and a stay of execution shall have been obtained pending
such appeal or review.

SECTION 1403.     SUBROGATION.

         Subject to the payment in full of all Senior Indebtedness, the Holders
of the Securities shall be subrogated (equally and ratably with the holders of
all obligations of the Corporation which by their express terms are subordinated
to Senior Indebtedness of the Corporation to the same extent as the Securities
are subordinated and which are entitled to like rights of subrogation) to the
rights of the holders of Senior Indebtedness to receive payments or
distributions of cash, property or securities of the Corporation applicable to
the Senior Indebtedness until all amounts owing on the Securities shall be paid
in full, and as between the Corporation, its creditors other than holders of
such Senior Indebtedness and the Holders, no such payment or distribution made
to the holders of Senior Indebtedness by virtue of this Article that otherwise
would have been made to the Holders shall be deemed to be a payment by the
Corporation on account of such Senior Indebtedness, it being understood that the
provisions of

                                       67
<PAGE>   74

this Article 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
Indebtedness, on the other hand.

SECTION 1404.     OBLIGATION OF CORPORATION UNCONDITIONAL.

         Nothing contained in this Article or elsewhere in this Indenture or in
the Securities is intended to or shall impair, as among the Corporation, its
creditors other than the holders of Senior Indebtedness and the Holders, the
obligation of the Corporation, which is absolute and unconditional, to pay to
the Holders the principal of and any premium or interest on the Securities as
and when the same shall become due and payable in accordance with their terms,
or is intended to or shall affect the relative rights of the Holders and
creditors of the Corporation other than the holders of Senior Indebtedness, nor
shall anything herein or therein prevent the Trustee or any Holder from
exercising all remedies otherwise permitted by applicable law upon default under
this Indenture, subject to the rights, if any, under this Article of the holders
of Senior Indebtedness in respect of cash, property or securities of the
Corporation received upon the exercise of any such remedy.

         Upon payment or distribution of assets of the Corporation referred to
in this Article, the Trustee and the Holders shall be entitled to rely upon any
order or decree made by any court of competent jurisdiction in which any such
dissolution, winding-up, liquidation or reorganization proceeding affecting the
affairs of the Corporation is pending or upon a certificate of the trustee in
bankruptcy, receiver, assignee for the benefit of creditors, liquidating trustee
or agent or other person making any payment or distribution, delivered to the
Trustee or to the Holders, for the purpose of ascertaining the persons entitled
to participate in such payment or distribution, the holders of the Senior
Indebtedness and other indebtedness of the Corporation, the amount thereof or
payable thereon, the amount or amounts paid or distributed thereon and all other
facts pertinent thereto or to this Article.

         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
Indebtedness (or a trustee or representative on behalf of such holder) to
establish that such notice has been given by a holder of Senior Indebtedness or
a trustee or representative on behalf of any such holder or holders. In the
event that the Trustee determines in good faith that further evidence is
required with respect to the right of any Person as a holder of Senior
Indebtedness to participate in any payment or distribution pursuant to this
Article, the Trustee may request such Person to furnish evidence to the
reasonable satisfaction of the Trustee as to the amount of Senior Indebtedness
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, and, if such evidence is not furnished, the
Trustee may defer payment to such Person pending judicial determination as to
the right of such Person to receive such payment.

SECTION 1405.     PAYMENTS ON SECURITIES PERMITTED.

         Nothing contained in this Article or elsewhere in this Indenture or in
the Securities shall affect the obligations of the Corporation to make, or
prevent the Corporation from making,

                                       68
<PAGE>   75

payment of the principal of or any premium or interest on the Securities in
accordance with the provisions hereof and thereof, except as otherwise provided
in this Article.

SECTION 1406.     EFFECTUATION OF SUBORDINATION BY TRUSTEE.

         Each Holder of Securities, by his acceptance thereof, authorizes and
directs the Trustee in his, her or its behalf to take such action as may be
necessary or appropriate to effectuate the subordination provided in this
Article and appoints the Trustee his, her or its attorney-in-fact, as the case
may be, for any and all such purposes.

SECTION 1407.     KNOWLEDGE OF TRUSTEE.

         The Corporation shall give prompt written notice to the Trustee of any
fact known to the Corporation which would prohibit the making of any payment of
moneys to or by the Trustee in respect of the Securities pursuant to the
provisions of this Article. Notwithstanding the provisions of this Article or
any other provisions of this Indenture, the Trustee shall not be charged with
knowledge of the existence of any facts that would prohibit the making of any
payment of moneys to or by the Trustee, or the taking of any other action by the
Trustee, unless and until the Trustee shall have received written notice thereof
mailed or delivered to the Trustee at its Corporate Trust Office from the
Corporation, any Holder, any paying agent or the holder or representative of any
Senior Indebtedness; provided that if at least two Business Days prior to the
date upon which by the terms hereof any such moneys may become payable for any
purpose (including, without limitation, the payment of the principal or any
premium or interest on any Security) the Trustee shall not have received with
respect to such moneys the notice provided for in this Section, then, anything
herein contained to the contrary notwithstanding, the Trustee shall have full
power and authority to receive such moneys and to apply the same to the purpose
for which they were received and shall not be affected by any notice to the
contrary that may be received by it within two Business Days prior to or on or
after such date.

SECTION 1408.     TRUSTEE MAY HOLD SENIOR INDEBTEDNESS.

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

SECTION 1409.     RIGHTS OF HOLDERS OF SENIOR INDEBTEDNESS NOT IMPAIRED.

         No right of any present or future holder of any Senior Indebtedness to
enforce the subordination herein shall at any time or in any way be prejudiced
or impaired by any act or failure to act on the part of the Corporation or by
any noncompliance by the Corporation with the terms, provisions and covenants of
this Indenture, regardless of any knowledge thereof which any such holder may
have or be otherwise charged with.

                                       69
<PAGE>   76

         With respect to the holders of Senior Indebtedness, (i) the duties and
obligations of the Trustee shall be determined solely by the express provisions
of this Indenture; (ii) the Trustee shall not be liable except for the
performance of such duties and obligations as are specifically set forth in this
Indenture; (iii) no implied covenants or obligations shall be read into this
Indenture against the Trustee; and (iv) the Trustee shall not be deemed to be a
fiduciary as to such holders.

SECTION 1410.     TRUST MONEYS NOT SUBORDINATED.

         Notwithstanding anything contained herein to the contrary, payments
from money or Government Obligations held in trust under Article Four or Article
Thirteen by the Trustee for the payment of principal of and any premium or
interest on the Securities of any series shall not be subordinated to the prior
payment of any Senior Indebtedness of the Corporation or subject to the
restrictions set forth in this Article and none of the Holders shall be
obligated to pay over any such amount to the Corporation or any holder of Senior
Indebtedness or any other creditor of the Corporation.

SECTION 1411.     ARTICLE APPLICABLE TO PAYING AGENTS.

         In case at any time any paying agent other than the Trustee shall have
been appointed by the Corporation and be then acting hereunder, the term
"Trustee" as used in this Article shall in such case (unless the context shall
otherwise require) be construed as extending to and including such paying agent
within its meaning as fully for all intents and purposes as if such paying agent
were named in this Article in addition to or in place of the Trustee; provided,
however, that Sections 1407 and 1408 shall not apply to the Corporation if it
acts as its own paying agent.

SECTION 1412.     TRUSTEE; COMPENSATION NOT PREJUDICED.

         Nothing in this Article shall apply to claims of, or payments to, the
Trustee pursuant to Section 607.

                                  ARTICLE XV.
                           IMMUNITY OF INCORPORATORS,
                      STOCKHOLDERS, OFFICERS AND DIRECTORS

SECTION 1501.     INDENTURE AND SECURITIES SOLELY CORPORATE OBLIGATIONS.

         No recourse for the payment of the principal of or any premium or
interest on any Security, or for any claim based thereon or otherwise in respect
thereof, and no recourse under or upon any obligation, covenant or agreement of
the Corporation in this Indenture or in any supplemental indenture, or in any
Security, or because of the creation of any indebtedness represented thereby,
shall be had against any incorporator, stockholder, officer or director, as
such, past, present or future, of the Corporation or of any successor
corporation, either directly or through the Corporation or any successor
corporation, whether by virtue of any constitution, statute or rule of law, or
by the enforcement of any assessment or penalty or otherwise; it being

                                       70
<PAGE>   77

expressly understood that all such liability is hereby expressly waived and
released as a condition of, and as a consideration for, the execution of this
Indenture and the issue of the Securities.

         This instrument may be executed in any number of counterparts, each of
which so executed shall be deemed to be an original, but all such counterparts
shall together constitute but one and the same instrument.

                            (Signature page follows)

between COMCAST CORPORATION, a Pennsylvania corporation (the "Company," as
further defined in Section 12), and BRIAN L. ROBERTS (the "Executive," as
further defined in Section 1).

                                 R E C I T A L S

                  WHEREAS, the Executive has been employed by the Company for
over 20 years and is currently its President and a member of its Board of
Directors and Executive Committee; and

                  WHEREAS, during the Executive's tenure as President of the
Company, the Company has enjoyed outstanding success, due in large part to
Executive's leadership and to transactions initiated by him; and

                  WHEREAS, the Company's Board of Directors (the "Board"), as
well as the Board's Compensation Committee (the "Compensation Committee") and
its Subcommittee on Performance-Based Compensation (the "Subcommittee"),
recognize that the Executive's contribution to the growth and success of the
Company is substantial and that without his continued leadership the Company
would not have achieved and maintained its current preeminent status in the
cable television industry nor would the Company have achieved its performance
levels or successfully consummated the many strategic transactions that have
closed during the past five years; and

                  WHEREAS, the Board desires to assure the Company of the
Executive's continued employment in an executive capacity and to compensate him
therefor; and

                  WHEREAS, the Board has established the Subcommittee as a
subcommittee of its Compensation Committee comprised of independent outside
directors and which has the

<PAGE>

responsibility for establishing the criteria for the payment of
performance-based compensation to the Executive and the Company's other senior
executive officers; and

                  WHEREAS, the Subcommittee has engaged in discussions with
Executive over a period of more than one year regarding formalizing the terms of
Executive's continued employment, and has sought advice from two independent
compensation consultants regarding the principal terms of such employment,
including Executive's salary, bonus, and stock-based compensation; and

                  WHEREAS, on June 21, 1999, the Company's shareholders approved
amendments to the Company's 1996 Stock Option Plan and 1996 Executive Cash Bonus
Plan that make such plans consistent with the terms set forth herein; and

Split-Dollar Insurance Plan (together, the "Split-Dollar Insurance Plans"), each
of which provides a death benefit to the Executive's family following the death
of the last survivor of the Executive and his spouse and a repayment of all
loans advanced by the Company on behalf of the Executive and his spouse for the
purpose of assisting the Executive to maintain in force the split-dollar
insurance policies issued thereunder; and

                  WHEREAS,  the Executive is willing to commit  himself to serve
the Company on the terms herein provided;

                                      -2-
<PAGE>

                  NOW THEREFORE, in consideration of the foregoing and of the
respective covenants and agreements of the parties herein contained, the parties
hereto agree as follows:

                  1.  Employment. The Company hereby agrees to continue to
employ the Executive and the Executive hereby agrees to continue to serve the
Company, on the terms and conditions set forth herein, for a term commencing on
the date hereof and expiring on June 30, 2003 (unless sooner terminated as
hereinafter set forth).

                  2.  Position and Duties. The Executive shall serve as the
President of the Company, and, in such position, he shall have such powers and
duties as may from time to time be prescribed by the Board in accordance with
the Company's By-Laws. Executive shall devote substantially all of his working
time and effort to the business and affairs of the Company. It is recognized
that the Executive has outside interests, including, but not limited to, serving
as a director on the boards of other corporations and community and charitable
organizations, and that the Executive may devote a reasonable amount of time to
such outside interests. Moreover, the provisions of this Section 2 shall not
prevent the Executive from investing his assets in such form and manner as he
chooses; provided, however, that the Executive shall not have any personal
interest, direct or indirect (other than through the Company or its
subsidiaries), financial or otherwise, in any supplier to, buyer from, or
competitor of the Company unless such interest has been approved by the
Compensation Committee or Subcommittee or such interest is, or arises solely
from ownership of, less than two percent (2%) of the outstanding capital stock
of such supplier, buyer or competitor and such capital stock is available to the
general public through trading on any national, regional or over-the-counter
securities market. In connection with his employment by the

                                      -3-
<PAGE>

Company the Executive shall be based at the Company's principal executive
offices in the Delaware Valley.

                  3.  Compensation and Related Matters.

                      (a) Base Salary. For each full year included in the term
of this Agreement the Company shall pay the Executive a base salary ("Base
Salary") for all services to be rendered by the Executive hereunder of One
Million Dollars ($1,000,000) per annum (less appropriate deductions), payable in
installments at such times as the Company customarily pays its other senior
executive officers (but in any event no less often than monthly). Effective as
of each January 1 (beginning in 2000) or such other date as may be determined by
the Subcommittee, the Subcommittee shall adjust the Executive's Base Salary to
reflect the Executive's contribution to the growth and success of the Company.
Once established at an increased annual rate, the Executive's Base Salary
hereunder shall not thereafter be reduced unless such reduction is pursuant to
an overall plan to reduce the salaries of all senior executive officers of the
Company.

                      (b) Performance-Based Compensation under Cash Bonus Plan.
Effective January 1, 1999, Executive shall be entitled to an annual
performance-based cash bonus ("Cash Bonus") of up to 150% of the Base Salary for
any year during the term hereof, determined in accordance with, and upon
satisfaction of, the performance based standards contained in the Cash Bonus
Plan; provided, that if the conditions for full payment of a Cash Bonus under
the Cash Bonus Plan are met in any year, the Compensation Subcommittee shall not
have discretion to reduce Employee's Cash Bonus for such year below 100% of his
Base Salary for such year.

                                      -4-
<PAGE>

                      (c) Options. Executive shall receive grants of options to
purchase no fewer than 11,000,000 shares of the Company's Class A Special Common
Stock (such number of shares reflecting the stock split in the form of a 100%
stock dividend effected by the Company May 4, 1999 (the "Stock Split")) pursuant
to the terms of the Company's 1996 Stock Option Plan, as such plan may be
amended from time to time, or any equivalent stock option plan, including,
without limitation, an option price equal to fair market value of the underlying
stock on the date of grant (except for "incentive stock options," which may have
a higher exercise price), and a duration of at least ten years (except for
"incentive stock options" which may have a duration of five years). Such options
shall be or have been granted as follows: 3,000,000 shares on June 16, 1998 (an
original grant of options to purchase 1,500,000 shares, adjusted to 3,000,000
shares to reflect the Stock Split), and 1,000,000 shares on each of the second
business days of each fiscal quarter in 1999 and 2000 (i.e., for grants prior to
May 4, 1999, 500,000 shares adjusted to 1,000,000 shares to reflect the Stock
Split), or such earlier date as the Subcommittee may determine in its sole
discretion. Such options shall be "incentive stock options" under the Internal
Revenue Code to the maximum extent permitted by law. In the event of stock
dividends, stock splits, reverse stock splits, recapitalizations, or similar
events applicable to the Class A Special Common Stock that occur subsequent to
the date hereof (other than the Stock Split, which is taken into account
herein), the number of options to be granted hereunder that have not been
granted prior to the date of such event shall be adjusted to reflect the effect
of such event.

                      (d) Expenses. During the term of this Agreement, the
Executive shall be entitled to receive prompt reimbursement for all reasonable
expenses incurred by him (in accordance

                                      -5-
<PAGE>

with the policies and procedures established from time to time by the Board for
its senior executive officers) in performing services hereunder, provided that
the Executive properly accounts therefor in accordance with Company policy.

                      (e) Other Benefits. Except as otherwise provided herein,
the Executive shall continue to be eligible to participate in all employee
benefit plans and arrangements in effect on the date of this Agreement and shall
continue to obtain benefits thereunder, including, without limitation, each
bonus plan, savings and profit sharing plan, supplemental pension and retirement
plan, stock ownership plan, stock purchase plan, stock option plan, life
insurance plan, medical insurance plan, disability plan, dental plan and
health-and-accident plan. Except as otherwise provided herein or as required by
law, the Company shall not make any changes in any such employee benefit plans
or arrangements which would adversely affect the Executive's rights or benefits
thereunder, unless such change occurs pursuant to a program applicable to all
executives of the Company and does not result in a proportionately greater
reduction in the rights of or benefits to the Executive as compared with any
other executive of the Company. The Executive shall be entitled to participate
in or receive benefits under any employee benefit plan or arrangement made
available by the Company in the future to its executives and key management
employees, subject to and on a basis consistent with the terms, conditions and
overall administration of such plan or arrangement. No amount paid to the
Executive under any plan or arrangement presently in effect or made available in
the future shall be deemed to be in lieu of the Base Salary or Bonus payable to
the Executive pursuant to paragraph (a) of this Section.

                                      -6-

                      (f) Vacations. The Executive shall be entitled to not
fewer than the same number of paid vacation days in each calendar year as he is
currently entitled. The Executive shall also be entitled to all paid holidays
given by the Company to its senior executive officers.

                      (g) Perquisites. So long as he serves as President, the
Executive shall be entitled to continue to receive not less than the perquisites
and fringe benefits appertaining to the office of the President in accordance
with the Company's present practice.

                      (h) Deferred Compensation. So long as the Company's 1996
Deferred Compensation Plan, or any other deferred compensation plan in which
senior executives of the Company are eligible to participate, is in effect, if
the Executive and the Company so agree in writing prior to December 31 of any
calendar year (or such earlier date as may be required by the Company's 1996
Deferred Compensation Plan or any other applicable deferred compensation plan),
and to the extent so agreed, the payment of all or any portion of the
compensation payable to the Executive in the next following calendar year
(including, without limitation, any compensation payable in such year by reason
of having been deferred from a prior year pursuant to an election made prior to
June 30 of the year prior to the year of distribution in accordance with Section
3.6.2 of the 1996 Deferred Compensation Plan) shall be deferred to a subsequent
calendar year selected by the Executive pursuant to the terms of the 1996
Deferred Compensation Plan or such other deferred compensation plan. Once a
deferral has been agreed to pursuant to this Section 3(h), the deferred amount
shall be subject to the same terms and conditions as apply to deferrals under
the Company's 1996 Deferred Compensation Plan or such other deferred
compensation plan then applicable, including, without limitation, the crediting
of interest. Nothing in this Section 3(h) shall

                                      -7-
<PAGE>

require the Company to maintain the 1996 Deferred Compensation Plan in effect,
to maintain the current terms of such plan, or to adopt any other deferred
compensation plan.

                      (i) Life Insurance Agreement. The compensation provided
herein is in addition to, and not in limitation of, the compensation provided by
the Term Life Insurance Premium and Tax Bonus Agreement dated as of September
23, 1998 (the "Life Insurance Agreement"), which agreement continues in effect.

                      (j) Funding of Trust. Prior to the occurrence of a "Change
of Control" (as hereinafter defined), the Company shall establish a grantor
trust (the "Trust"), the terms of which shall be consistent with the
requirements applicable under the Code in order to avoid the constructive
receipt of the assets held in the Trust by the Executive. The trust document for
the Trust shall be in a form that is satisfactory to both the Company and the
Executive, and may, but need not, be in substantially the same form as the model
trust agreement published by the IRS in Revenue Procedure 92-64. The trustee of
the Trust shall be such person or institution acceptable both to the Company and
the Executive. The Company shall contribute such amounts in cash or such assets
as it deems appropriate for the purpose of funding the compensation and/or death
benefits payable under the terms of this Agreement and such other compensation
or plans or arrangements that may be in effect. Upon the occurrence of a Change
of Control, the Trust, if not already irrevocable, shall become irrevocable. The
Company shall be required immediately prior to a Change of Control (or in the
event the Company does not receive notice of a proposed Change of Control prior
to such event), immediately upon a Change of Control, to contribute to the Trust
(i) an amount equal to the minimum base compensation and Bonus Payment payable
under this Agreement for the then-

                                      -8-
<PAGE>

remaining term of this Agreement (assuming that all conditions to payment of a
full Bonus under the Cash Bonus Plan were met, and disregarding any possible
decrease in Base Salary), and (ii) the present value of all deferred
compensation benefits payable to the Executive under the terms of any
nonqualified deferred compensation arrangement in which the Executive is a
participant, including, but not limited to, the Company's 1996 Deferred
Compensation Plan and the Company's Supplemental Executive Retirement Plan.

                      In addition, the Company shall have the further obligation
following a Change of Control to make such additional contributions to the
Trust, from time to time (but determined no less than annually), as may become
necessary to fully fund the benefits described above, determined in the same
manner as the initial funding obligation is determined. The assets contributed
to the Trust shall, except to the extent otherwise provided in the trust
agreement in the case of the bankruptcy or insolvency of the Company, be used
exclusively for the purpose of provide to the Executive the benefits described
above until all such benefits have been fully paid, at which time the Trust may
be terminated and any remaining assets revert back to the Company.
Notwithstanding the foregoing, to the extent benefits are paid by the Company
rather than out of assets held in the Trust, the trustee may reimburse the
Company out of the Trust such amounts as have been paid as benefits to the
Executive by the Company, but only to the extent that such reimbursement does
not cause the Trust to be less than fully funded, determined in the same manner
as the initial funding obligation is determined.

                      For purposes of this Agreement, a "Change of Control"
shall be deemed to have occurred on the date that Executive and members of his
immediate family (or trusts for their benefit)

                                      -9-
<PAGE>

first cease to beneficially own at least 50% of the voting power of the Company.
Present value shall be calculated based on the then current yields of U.S.
Treasury Bonds maturing on the respective dates on which the payments being
valued become due.

                  4.  Termination. The Executive's employment hereunder may be
terminated without any breach of this Agreement only under the following
circumstances:

                      (a) Death. The Executive's employment hereunder shall
terminate upon his death.

                      (b) Disability. If, as a result of the Executive's
incapacity due to physical or mental illness, the Executive shall have been
absent from his duties hereunder for 180 consecutive calendar days, and within
thirty (30) days after written notice of termination is given (which may occur
before or after the end of such 180 day period), shall not have returned to the
performance of his duties hereunder on the basis provided for in Sections 1 and
2 hereof, the Company may terminate the Executive's employment hereunder.

                      (c) Cause. The Company may terminate the Executive's
employment hereunder for Cause. For purposes of this Agreement, the Company
shall have "Cause" to terminate the Executive's employment hereunder upon (A)
the willful and continued failure by the Executive either to substantially
perform his duties hereunder or to comply with the provisions of the Company's
Code of Ethics and Business Conduct (other than a failure following a Change of
Control, as defined in Section 3(j), or a failure resulting from the Executive's
incapacity due to physical or mental illness) for a period of sixty (60) days
after demand for

                                      -10-
<PAGE>

substantial performance or compliance is delivered by the Company specifically
identifying the manner in which the Company believes the Executive has not
substantially performed his duties or has not complied; or (B) the willful
engaging by the Executive in misconduct which is materially injurious to the
Company, monetarily or otherwise, or (C) the willful breach by the Executive
either during or after the term of this Agreement of any material provision of
this Agreement, including, but not limited to, Sections 6, 7 and 8 hereof. For
purposes of this paragraph, no act, or failure to act, on the Executive's part
shall be considered "willful" unless done, or omitted to be done, by him not in
good faith and without reasonable belief that his action or omission was in the
best interest of the Company. Notwithstanding the foregoing, the Executive shall
not be deemed to have been terminated for Cause unless and until there shall
have been delivered to the Executive a copy of a resolution, duly adopted by the
affirmative vote of not less than two-thirds of the entire membership of the
Board (without counting Executive or any parent or spouse of Executive) at a
meeting of the Board called and held for such purpose (after reasonable notice
to the Executive and an opportunity for him, together with his counsel, to be
heard before the Board), finding that in the good faith opinion of the Board the
Executive was guilty of conduct set forth above in clause (A), (B), or (C) of
the preceding sentence, and specifying the particulars thereof in detail.

                      (d) Notice of Termination. Any termination of the
Executive's employment by the Company shall be communicated by written Notice of
Termination to the Executive. For purposes of this Agreement, a "Notice of
Termination" shall mean a notice which shall indicate the specific termination
provision in this Agreement relied upon and shall set forth in

                                      -11-
<PAGE>

reasonable detail the facts and circumstances claimed to provide a basis for
termination of the Executive's employment under the provision so indicated.

                      (e) Date of Termination. "Date of Termination" shall mean
(i) if the Executive's employment is terminated by his death, the date of his
death, (ii) if the Executive's employment is terminated pursuant to paragraph
(b), above, thirty (30) days after Notice of Termination is given (provided that
the Executive shall not have returned to the performance of his duties on the
basis provided for in Section 2 hereof during such thirty (30) day period) or
(iii) if the Executive's employment is terminated pursuant to paragraph (c)
above, the date specified in the Notice of Termination; provided that if within
thirty (30) days after a Notice of Termination is given the party receiving such
Notice of Termination notifies the other party that a dispute exists concerning
the termination, the Date of Termination shall be the date on which the dispute
is finally determined, either by mutual written agreement of the parties, by a
binding and final arbitration award or by a final judgment, order or decree of a
court of competent jurisdiction (the time of appeal therefrom having expired and
no appeal having been perfected).

                  5.  Compensation Upon Termination or During Disability.

                      (a) If during the term of this Agreement the Executive's
employment shall be terminated by reason of his death, the Company shall
continue to pay to the Executive's spouse, if, but only if, the spouse survives
the Executive, the Executive's then Base Salary, on a monthly basis for a period
of five (5) years, provided that, notwithstanding the foregoing, the payments to
the Executive's surviving spouse shall only be made during her lifetime and
shall cease with the payment due immediately following her death. This death
benefit shall be in addition to (x) the Company

                                      -12-
<PAGE>

hereby agreeing to continue, for the benefit of Executive's spouse during her
lifetime, all health plan benefits which are available from time to time to the
Company's highest paid employee and (y) any other payments the Executive's
spouse, beneficiaries or estate may be entitled to receive pursuant to this
Agreement (including, but not limited to, his Cash Bonus with respect to any
period then ended which would have accrued to the Executive on the basis of the
Company's performance but which has not yet been paid) and any pension or
employee benefit plan or life insurance policy presently maintained by the
Company.

                      (b) During any period that the Executive fails to perform
his duties hereunder as a result of incapacity due to physical or mental illness
prior to a termination pursuant to Section 4(b) hereof, the Executive shall
continue to receive his Base Salary until the Executive's employment is
terminated pursuant to Section 4(b) hereof or until the end of the term of this
Agreement, whichever occurs first (including, but not limited to, his Cash Bonus
with respect to any period prior to the date of termination which would have
accrued to the Executive on the basis of the Company's performance but which has
not yet been paid) and any pension or employee benefit plan or life insurance
policy presently or then maintained by the Company. In the event of termination
pursuant to Section 4(b) hereof, the Executive shall be paid for five (5) years,
on a monthly basis, an annual amount equal to his Base Salary at the rate in
effect at the time the Notice of Termination is given and the Company shall also
make the payments required pursuant to Section 7 hereof. In the event the
Executive dies before the end of the five (5) year payment period, the remaining
payments shall be made to the Executive's spouse, if, but only if, the spouse
survives the Executive, but, notwithstanding the foregoing, the payments to the
Executive's surviving spouse

                                      -13-
<PAGE>

shall only be made during her lifetime and shall cease with the payment due
immediately following her death. The death benefit provided in this Section 5(b)
shall be in lieu of, and not in addition to, the benefits provided in the first
sentence of Section 5(a) hereof.

                      (c) If the Executive's employment shall be terminated for
Cause, the Company shall pay the Executive his Base Salary due through the Date
of Termination at the rate in effect at the time the Notice of Termination is
given and the Company shall have no further obligation to the Executive under
this Agreement, including, but not limited to, the obligation to make the
payments provided for in Section 3 hereof.

                      (d) If, in breach of this Agreement, the Company shall
terminate the Executive's employment other than pursuant to Section 4(b) or 4(c)
hereof (it being understood that a purported termination pursuant to Section
4(b) or 4(c) hereof which is disputed and finally determined not to have been
proper shall be a termination by the Company in breach of this Agreement), then:

                          (i) the Company shall pay the Executive his Base
Salary through the Date of Termination at the rate in effect at the time the
Notice of Termination is given as well as any other amount, including his Cash
Bonus with respect to any period then ended which would have accrued to the
Executive on the basis of the Company's performance but which has not yet been
paid to him;

                          (ii) subsequent to the Date of Termination, the
Company shall pay as severance pay to the Executive on a monthly basis (or, in
the case of his Cash Bonus, on the basis provided in the Cash Bonus Plan) for
the remaining term of this Agreement an annual amount equal

                                      -14-
<PAGE>

to the Executive's Base Salary at the highest annual rate in effect at any time
during the portion of the term immediately preceding the Date of Termination and
his Cash Bonus; provided that should the Executive die before the end of the
remaining term of this Agreement, the Executive's surviving spouse shall be
entitled to the death benefit provided in Section 5(a) hereof, and all benefits
referred to in the last sentence of Section 5(a) hereof, as if the Executive's
employment had been terminated by reason of his death;

                          (iii) the Company shall maintain in full force and
effect for the continued benefit of the Executive (and for his surviving spouse,
as provided in paragraph (ii) hereinabove) for the remaining term of this
Agreement all (x) health plan benefits available from time to time to the
Company's highest paid employee and (y) employee benefit plans and programs in
which the Executive was entitled to participate immediately prior to the Date of
Termination, including, without limitation, the Split-Dollar Arrangements. At
the end of the period of coverage, the Executive shall have the option to have
assigned to him at no cost and with no apportionment of prepaid premiums any
assignable insurance policy owned by the Company which relates specifically to
him.

                      (e) The Executive shall not be required to mitigate the
amount of any payment provided for in this Section 5 by seeking other employment
or otherwise, nor shall the amount of any payment provided for in this Section 5
be reduced by any compensation earned by the Executive as a result of employment
by another employer after the Date of Termination, or otherwise.

                                      -15-
<PAGE>

                      (f) Notwithstanding anything herein to the contrary, in
the event the Executive's employment is terminated on or after the occurrence of
a Change of Control, as defined in Section 3(j), such termination shall in no
circumstances be treated under the terms of this Agreement as a termination for
Cause, and the Executive shall be entitled to the same benefits as are payable
with respect to a termination of the Executive's employment subject to the
provisions of Section 5(d).

                  6.  Confidential Information. The Company (as hereinafter
specially defined for purposes of Sections 6 through 9 hereof), pursuant to the
Executive's employment hereunder, provides him access to and confides in him
business methods and systems, techniques and methods of operation developed at
great expense by the Company ("Trade Secrets") and which the Executive
recognizes to be unique assets of the Company's business. The Executive shall
not, during or at any time after the term of this Agreement, directly or
indirectly, in any manner utilize or disclose to any person, firm, corporation,
association or other entity, except (i) where required by law, (ii) to
directors, consultants or employees of the Company in the ordinary course of his
duties or (iii) during his employment and in the ordinary course of his services
as President for such use and disclosure as he shall reasonably determine to be
in the best interest of the Company: (a) any such Trade Secrets, (b) any sales
prospects, customer lists, products, research or data of any kind, or (c) any
information relating to strategic plans, sales, costs, profits or the financial
condition of the Company or any of its customers or prospective customers, which
are not generally known to the public or recognized as standard practice in the
industry in which the Company shall be engaged. The Executive further covenants
and agrees that he will promptly deliver to the Company all tangible

                                      -16-
<PAGE>

evidence of the knowledge and information described in (a), (b) and (c), above,
prior to or at the termination of the Executive's employment.

                  7.  Prohibited Public Statements. The Executive shall not,
either during or at any time after the termination of his employment, make any
public statement (including a private statement reasonably likely to be repeated
publicly) reflecting adversely on the Company and its business prospects, except
for such statements which during the Executive's employment he may be required
to make in the ordinary course of his service as President.

                  8.  Noncompetition, Noninterference and Nonsolicitation.

                      (a) Subject to the geographic limitation of Section 8(b)
hereof, the Executive during the term of this Agreement and for a period of two
(2) years following termination of employment in accordance with this Agreement
shall not, directly or indirectly, on his behalf or on behalf of any other
person, firm, corporation, association or other entity, as an employee or
otherwise, engage in, or in any way be concerned with or negotiate for, or
acquire or maintain any ownership interest in any business or activity which is
the same as or competitive with that conducted by the Company at the termination
of his employment, or which was engaged in or developed by the Company at any
time during the term of this Agreement for specific implementation in the
immediate future by the Company.

                      (b) The Executive acknowledges that the Company is engaged
in business throughout the United States and in various foreign countries and
that the Company intends to expand the geographic scope of its activities.
Accordingly and in view of the nature of his position and responsibilities, the
Executive agrees that the provisions of this Section shall be applicable to

                                      -17-
<PAGE>

each state and each foreign country, possession or territory in which the
Company may be engaged in business during the term of this Agreement, or, with
respect to the Executive's obligations following termination of his employment,
at the termination of his employment or at any time within the 12-month period
following the effective date of his termination of employment.

                      (c) The Executive agrees that for a period of two (2)
years following termination of employment in accordance with this Agreement, the
Executive will not, directly or indirectly, for himself or on behalf of any
third party at any time in any manner, request or cause any of the Company's
customers to cancel or terminate any existing or continuing business
relationship with the Company; solicit, entice, persuade, induce, request or
otherwise cause any employee, officer or agent of the Company to refrain from
rendering services to the Company or to terminate his or her relationship,
contractual or otherwise, with the Company; induce or attempt to influence any
supplier to cease or refrain from doing business or to decline to do business
with the Company; divert or attempt to divert any supplier from the Company; or
induce or attempt to influence any supplier to decline to do business with any
businesses of the Company as such businesses are constituted immediately prior
to the termination of employment.

                      (d) The Executive agrees that for a period of two (2)
years following his termination of employment in accordance with this Agreement,
the Executive will not directly or indirectly, for himself or on behalf of any
third party, solicit for business, accept any business from or otherwise do, or
contract to do, business with any person or entity who, at the time of, or any
time during the twelve (12) months preceding such termination, was an active
customer or was actively

                                      -18-
<PAGE>

solicited by the Company according to the books and records of the Company and
within the knowledge, actual or constructive of the Executive.

                      (e) Notwithstanding anything to the contrary in this
Section 8, the prohibitions and agreements contained in subsections (a), (c),
and (d) shall terminate immediately upon any termination of Executive's
employment hereunder following a Change of Control.

                  9.  Equitable Remedies. The Executive acknowledges that his
compliance with the covenants in Sections 6, 7, and 8 of this Agreement is
necessary to protect the good will and other proprietary interests of the
Company and that, in the event of any violation by the Executive of the
provisions of Section 6, 7 or 8 of this Agreement, the Company will sustain
serious, irreparable and substantial harm to its business, the extent of which
will be difficult to determine and impossible to remedy by an action at law for
money damages. Accordingly, the Executive agrees that, in the event of such
violation or threatened violation by the Executive, the Company shall be
entitled to any injunction before trial from any court of competent jurisdiction
as a matter of course and upon the posting of not more than a nominal bond in
addition to all such other legal and equitable remedies as may be available to
the Company. The Executive further agrees that, in the event any of the
provisions of Sections 6, 7 and 8 of this Agreement are determined by a court of
competent jurisdiction to be contrary to any applicable statute, law or rule, or
for any reason to be unenforceable as written, such court may modify any of such
provisions so as to permit enforcement thereof as thus modified.

                  10. Successors; Related Companies; Binding Agreement.

                                      -19-
<PAGE>

                      (a) The Company will require any successor (whether direct
or indirect, by purchase, merger, consolidation or otherwise) to all or
substantially all of the business and/or assets of the Company, by agreement in
form and substance satisfactory to the Executive, to expressly assume and agree
to perform this Agreement in the same manner and to the same extent that the
Company would be required to perform it if no such succession had taken place.
Failure of the Company to obtain such agreement prior to the effectiveness of
any such succession shall be a breach of this Agreement and shall entitle the
Executive to compensation from the Company in the same amount and on the same
terms as he would be entitled to hereunder pursuant to Section 5(d) hereof,
except that for purposes of implementing the foregoing, the date on which any
such succession becomes effective shall be deemed the Date of Termination. As
used in this Agreement, "Company" shall mean the Company and any successor to
its business and/or assets as aforesaid which executes and delivers the
agreement provided for in this Section 10 or which otherwise becomes bound by
all the terms and provisions of this Agreement by operation of law.

                      (b) For purposes of Sections 6, 7 and 8 hereof the term
"Company" shall mean Comcast Corporation ("Comcast") as well as (i) each of its
more than fifty percent (50%) owned subsidiaries and (ii) each other entity in
which Comcast directly or indirectly has a greater than ten percent (10%) equity
interest, the fair market value of which interest is in excess of $50,000,000.
In determining Comcast's equity interest for purposes of this Section 10(b), any
equity interest which Comcast has an option to purchase shall be considered as
owned by Comcast.

                      (c) This Agreement and all rights of the Executive
hereunder shall inure to the benefit of and shall be binding upon the
Executive's personal or legal representatives,

                                      -20-
<PAGE>

executors, administrators, successors, heirs, distributees, devisees and
legatees. If the Executive should die while any amounts would still be payable
to him hereunder if he had continued to live, all such amounts, unless otherwise
provided herein, shall be paid in accordance with the terms of this Agreement to
the Executive's devisee, legatee, or other designee or, if there be no such
designee, to the Executive's estate.

                  11. Entire Agreement. This Agreement and the Life Insurance
Agreement constitute the full and complete understanding and agreement of the
Executive and the Company respecting the subject matter hereof, and supersede
all prior understandings and agreements, oral or written, express or implied.
This Agreement may not be modified or amended orally but only by an agreement in
writing, signed by the party against whom enforcement of any waiver, change,
modification, extension or discharge is sought.

                  12. Headings. The section headings of this Agreement are for
convenience of reference only and are not to be considered in the interpretation
of the terms and conditions of this Agreement.

                  13. Actions by Board. The Company is governed by its Board
and, accordingly, all references in this Agreement to the actions and discretion
of the Company are meant and deemed to refer to the actions and discretion of
the Board.

                  14. Notices. Any notice required or permitted to be given
under this Agreement shall be in writing and shall be deemed to have been given
when sent by certified mail, postage prepaid, addressed as follows:

                      If to the Company:

                                      -21-

                      Philadelphia, Pennsylvania 19102-2148

                      Attn:  Corporate Secretary

                      If to the Executive, at his last known personal residence.

                  Any party may change the persons and address to which notices
or other communications are to be sent by giving written notice of such change
to the other party in the manner provided herein for giving notice.

                  15. Waiver of Breach. No waiver by either party of any
condition or of the breach by the other of any term or covenant contained in
this Agreement, whether by conduct or otherwise, in any one or more instances
shall be deemed or construed as a further or continuing waiver of any such
condition or breach or a waiver of any other condition, or of the breach of any
other term or covenant set forth in this Agreement. Moreover, the failure of
either party to exercise any right hereunder shall not bar the later exercise
thereof.

                  16. Nonalienation. The Executive shall not pledge,
hypothecate, anticipate or in any way create a lien upon any amounts provided
under this Agreement. This Agreement and the benefits payable hereunder shall
not be assignable by either party without the prior written consent of the
other; provided, however, that nothing in this Section shall preclude the
Executive from designating a beneficiary to receive any benefit payable
hereunder upon his death, or the executors, administrators or other legal
representatives of the Executive or his estate from assigning any rights
hereunder to which they become entitled to the person or persons entitled
thereto.

                  19. Invalidity or Unenforceability. If any term or provision
of this Agreement is held to be invalid or unenforceable, for any reason, such
invalidity or enforceability shall not affect any other term or provision hereof
and this Agreement shall continue in full force and effect as if such invalid or
unenforceable term or provision (to the extent of the invalidity or
unenforceability) had not been contained herein.
