provided  under  this  Agreement  be  determined  in  accordance  with  fair and
reasonable  standards  and that no party  realize a profit nor incur a loss as a
result of the services rendered pursuant to this Agreement.

       (b) Each Company agrees to reimburse the Service  Provider for all direct
costs incurred on behalf of each Company and for all indirect costs which may be
charged to each Company as follows:

              (i) "Direct Costs" include costs incurred by the Service  Provider
for services provided  directly to the Companies,  including but not limited to:
(a) All  costs  incident  to any  employee  or  employees  who are  employed  in

<PAGE>

substantially similar tenor signed by such Holders in person or by agent duly
appointed in writing. 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 Company. Such
instrument or instruments (and the action embodied therein and evidenced

such instrument or instruments. Proof of execution of any such instrument or of

Indenture and conclusive in favor of the Trustee and the Company, if made in the
manner provided in this Section.

execution is by a signer acting in a capacity other than his individual
capacity, such certificate or affidavit shall also constitute sufficient proof
of his 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 reasonable manner which the Trustee deems sufficient.

        (c)    The ownership of Securities shall be proved by the Register.

authorization, direction, notice, consent, waiver or other Act, the Company may,
at its option, by or pursuant to an Officers' Certificate delivered to the
Trustee, fix in advance a record date for the determination of Holders entitled
to give such request, demand, authorization, direction, notice, consent, waiver
or other Act, but the Company shall have no obligation to do so. If such a
record date is fixed, such request, demand, authorization, direction, notice,
consent, waiver or other Act may be given before or after such record date, but
only the Holders of record at the close of business on such record date shall be
deemed to be Holders for the purposes of determining whether Holders of the
requisite proportion of Outstanding Securities have authorized or agreed to
consented to such request, demand, authorization, direction, notice, consent,
waiver or other Act, and for that purpose the Outstanding Securities shall be
computed as of such record date; provided that no such authorization, agreement
or consent by the Holders on such record date shall be deemed effective unless
it shall become effective pursuant to the provisions of clause (a) of this
Section 1.4 not later than six months after the record date.

        sufficient for every purpose hereunder (unless otherwise herein
        expressly provided) if in writing and mailed, first-class postage
        prepaid, to the Company addressed to it at AT&T Wireless Services, Inc.,
        7277 164th Avenue NE, Building 1, Redmond, Washington 98052, Attention:
        Chief Financial Officer or at any other address previously furnished in
        writing to the Trustee by the Company.

SECTION 1.6    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
or otherwise agreed to by a

                                      -13-
<PAGE>

Holder) if in writing and mailed, first-class postage prepaid, to each Holder
affected by such event, at his address as it appears in the Register, within the
time 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. Any notice mailed to a Holder in the manner herein prescribed
shall be conclusively deemed to have been received by such Holder, whether or
not such Holder actually receives such notice.

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

        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 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.

SECTION 1.7    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 1.8    SUCCESSORS AND ASSIGNS

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

SECTION 1.9    SEPARABILITY

        In case any provision of this Indenture or 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 1.10   BENEFITS OF INDENTURE

        Nothing in this Indenture or in the Securities, expressed or implied,
shall give to any Person, other than the parties hereto and their successors
hereunder and the Holders, any benefit or any legal or equitable right, remedy
or claim under this Indenture.

SECTION 1.11   GOVERNING LAW

        THIS INDENTURE AND THE SECURITIES SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK. This Indenture is subject to
the Trust Indenture Act and if any provision hereof limits, qualifies or
conflicts with the Trust Indenture Act, the Trust Indenture Act shall control.

SECTION 1.12   LEGAL HOLIDAYS

        In any case where any Interest Payment Date, Redemption Date, sinking
fund payment date, Stated Maturity or Maturity of any Security shall not be a
Business Day at any Place of Payment, then (notwithstanding any other provision
of this Indenture of any Security other than a provision in the Securities of
any series which specifically states that such provision shall apply in lieu of
this Section) payment of principal, premium, if any, or interest need not be
made at such Place of Payment on such date, but may be made on the next
succeeding Business Day at such Place of Payment with the same force and effect
as if made on such date; provided that no interest shall accrue on the amount so
payable for the period from and after such Interest Payment Date, Redemption
Date, sinking fund payment date, Stated Maturity or Maturity, as the case may
be.

SECTION 1.13   NO RECOURSE AGAINST OTHERS

        No director, officer, employee or stockholder, as such, of the Company
shall have any liability for any obligations of the Company under the Securities
or the Indenture or for any claim based on, in respect of or by reason of such
obligations or their creation. Each Holder by accepting a Security waives and
releases all such liability. The waiver and release are part of the
consideration for the issue of the Securities.

                                      -17-
<PAGE>

                (19) any other terms of the series (which terms shall not be
        inconsistent with the provisions of this Indenture), including any terms
        which may be required by or advisable under United States laws or
        regulations or advisable in connection with the marketing of Securities
        of the series.

        (c) All Securities of any one series shall be substantially identical
except as to denomination and the rate or rates of interest, if any, and Stated
Maturity, the date from which interest, if any, shall accrue and except as may
otherwise be provided in or pursuant to an Officers' Certificate pursuant to
this Section 3.1 or in an indenture supplemental hereto. All Securities of any
one series need not be issued at the same time and, unless otherwise provided, a
series may be reopened, without the consent of the Holders, for issuances of
additional Securities of such series or for the establishment of additional
terms with respect to the Securities of such series.

        (d) If any of the terms of the Securities of any series are established
by action taken pursuant to a Board Resolution, a copy of such Board Resolution
shall be certified by the Corporate Secretary or an Assistant Secretary of the
Company and delivered to the Trustee at

                                      -18-
<PAGE>

or prior to the delivery of the Officers' Certificate setting forth, or
providing the manner for determining, the terms of the Securities of such
series, and an appropriate record of any action taken pursuant thereto in
connection with the issuance of any Securities of such series shall be delivered
to the Trustee prior to the authentication and delivery thereof. With respect to
Securities of a series subject to a Periodic Offering, such Board Resolution or
Officers' Certificate may provide general terms 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 Company, or one or more of the Company's agents designated in
an Officers' Certificate, in accordance with the Company Order as contemplated
by the first proviso of the third paragraph of Section 3.3

SECTION 3.2    DENOMINATIONS

        The Securities of each series shall be issuable only in definitive
registered form without coupons and in such denominations as shall be specified
as contemplated by Section 3.1. In the absence of any such provisions 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 3.3    EXECUTION, AUTHENTICATION, DELIVERY AND DATING

        Securities shall be executed on behalf of the Company by the Chairman,
President or Chief Executive Officer and attested to by the Secretary of the
Company. The Company's seal shall be affixed to the Securities, or a facsimile
of such seal shall be engraved, printed, or otherwise reproduced on the
Securities. The signatures of such officers on the Securities may be manual or
facsimile signatures of the present or any future such authorized officers and
may be imprinted or otherwise reproduced on the Securities.

        Securities bearing the manual or facsimile signatures of individuals who
were at any time the proper officers of the Company shall bind the Company,
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, the Company may deliver Securities of
any series executed by the Company to the Trustee for authentication, together
with a Company Order for the authentication and make available for delivery 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 Company 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 a series have been established
by or pursuant to one or more Officers' Certificates as permitted by Sections
2.1 and 3.1, in authenticating such

                                      -19-
<PAGE>

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 315(a) through (d) of the Trust Indenture Act) shall be
fully protected in relying upon, an Opinion of Counsel stating,

                (1) that the forms and terms of such Securities have been
        established in conformity with the provisions of this Indenture; and

                (2) that such Securities, when authenticated and delivered by
        the Trustee and issued by the Company in the manner and subject to any
        conditions specified in such Opinion of Counsel, will constitute valid
        and legally binding obligations of the Company, enforceable in
        accordance with their terms, subject to customary exceptions;

provided, however, that, with respect to Securities of a series subject to a
Periodic Offering, the Trustee shall be entitled to receive such Opinion of
Counsel only once at or prior to the time of the first authentication of
Securities of such series and that the Opinion of Counsel above may state:

                (x) that the forms of such Securities have been, and the terms
        of such Securities (when established in accordance with such procedures
        as may be specified from time to time in a Company Order, all as
        contemplated by and in accordance with a Board Resolution or an
        Officers' Certificate pursuant to Section 3.1, as the case may be) will
        have been, established in conformity with the provisions of this
        Indenture; and

                (y) that such Securities, when (1) executed by the Company, (2)
        completed, authenticated and delivered by the Trustee in accordance with
        this Indenture, and (3) issued by the Company in the manner and subject
        to any conditions specified in such Opinion of Counsel, will constitute
        valid and legally binding obligations of the Company, enforceable in
        accordance with their terms, subject to customary exceptions.

        With respect to Securities of a series subject to a Periodic Offering,
the Trustee may conclusively rely, as to the authorization by the Company 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 other
documents delivered pursuant to Sections 2.1 and 3.1 of this Section, as
applicable, at or prior to the time of the first authentication of Securities of
such series unless and until it has received written notification that such
opinion or other documents have been superseded or revoked. In connection with
the authentication and delivery of Securities of a series subject to a Periodic
Offering, the Trustee shall be entitled to assume that the Company's
instructions to authenticate and deliver such Securities do not violate any
rules, regulations or orders of any governmental agency or commission having
jurisdiction over the Company.

        If the form or terms of the Securities of a series have been established
by or pursuant to one or more Officers' Certificates as permitted by Sections
2.1 and 3.1, the Trustee shall have the right to decline to authenticate such
Securities if the issue of such Securities pursuant to

                                      -20-
<PAGE>

this Indenture will adversely affect the Trustee's own rights, duties or
immunities under this Indenture or otherwise in a manner which is not reasonably
acceptable to the Trustee.

        Notwithstanding the provisions of Section 3.1 and of the two preceding
paragraphs, if all of the Securities of any series are not to be issued at one
time, it shall not be necessary to deliver the Officers' Certificate otherwise
required pursuant to Section 3.1 at or prior to the time of the authentication
of each Security of such series if the Officers' Certificate is delivered at or
prior to the authentication upon original issuance of the first Security of such
series to be issued.

        Each Security shall be dated the date of its authentication.

        No Security shall be entitled to any benefits under this Indenture or be
valid or obligatory for any purpose until authenticated by the manual signature
of one of the authorized signatories of the Trustee or an Authenticating Agent.
Such signature upon any Security shall be conclusive evidence, and the only
evidence, that such Security has been duly authenticated and delivered under
this Indenture and is entitled to the benefits of this Indenture.

        Notwithstanding the foregoing, if any Security shall have been
authenticated and delivered hereunder but never issued and sold by the Company,
and the Company shall deliver such Security to the Trustee for cancellation as
provided in Section 3.9 together with a written statement (which need not comply
with Section 1.2 and need not be accompanied by an Opinion of Counsel) stating
that such Security has never been issued and sold by the Company, for all
purposes of this Indenture such Security shall be deemed never to have been
authenticated and delivered hereunder and shall not be entitled to the benefits
of this Indenture.

SECTION 3.4    TEMPORARY SECURITIES

        Pending the preparation of definitive Securities of any series, the
Company may execute and, upon Company Order, the Trustee shall authenticate and
deliver temporary Securities of such series which are printed, lithographed,
typewritten, mimeographed or otherwise produced, in any authorized denomination,
substantially of the tenor and form 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 conclusively evidenced by their execution of such Securities.

        If temporary Securities of any series are issued, the Company will cause
permanent Securities of such series to be prepared without unreasonable delay.
After preparation of such permanent Securities, the temporary Securities shall
be exchangeable for such permanent Securities of like tenor upon surrender of
the temporary Securities of such series at the office or agency of the Company
pursuant to Section 9.2 in a Place of Payment for such series, without charge to
the Holder. Upon surrender for cancellation of any one or more temporary
Securities of any series, the Company shall execute and the Trustee shall
authenticate and deliver in exchange therefor a like principal amount of
Permanent Securities of the same series of authorized denominations and of like
tenor. Until so exchanged, the temporary Securities of

                                      -21-
<PAGE>

any series shall in all respects be entitled to the same benefits under this
Indenture as permanent Securities of such series except as otherwise specified
as contemplated by Section 3.1.

SECTION 3.5    REGISTRATION, REGISTRATION OF TRANSFER AND EXCHANGE

        The Company shall cause to be kept at the Corporate Trust Office of the
Trustee or in any office or agency to be maintained by the Company in accordance
with Section 9.2 in a Place of Payment a register (the "Register") in which,
subject to such reasonable regulations as it may prescribe, the Company shall
provide for the registration of Securities and the registration of transfers of
Securities. The Register shall be in written form or any other form capable of
being converted into written form within a reasonable time. The Trustee is
hereby appointed "Registrar" for the purpose of registering Securities and
transfers of Securities as herein provided.

        Upon surrender for registration of transfer of any Security of any
series at the office or agency maintained pursuant to Section 9.2 in a Place of
Payment for that series, the Company 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 a like aggregate principal amount and tenor.

        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 aggregate principal amount containing identical terms and provisions, upon
surrender of the Securities to be exchanged at such office or agency. Whenever
any Securities are so surrendered for exchange, the Company shall execute, and
the Trustee shall authenticate and deliver, the Securities which the Holder
making the exchange is entitled to receive.

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

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

        No service change shall be made for any registration of transfer or for
any exchange of Securities, but the Company may require payment of a sum
sufficient to cover any tax or other governmental charge that may be imposed in
connection with any registration or transfer or

                                      -22-
<PAGE>

exchange of Securities, other than exchanges pursuant to Section 3.4 or 10.7 not
involving any transfer.

        The Company shall not be required (i) to issue, register the transfer
of, or exchange any Securities for a period beginning at the opening of business
15 days before any selection for redemption of Securities of like tenor and of
the series of which such Security is a part and ending at the close of business
on the earliest date on which the relevant notice of redemption is deemed to
have been given to all Holders of Securities of like tenor and of such series to
be redeemed or (ii) to register the transfer of or exchange of any Security so
selected for redemption, in whole or in part, except the unredeemed portion of
any Security being redeemed in part.

SECTION 3.6    REPLACEMENT SECURITIES

        If a mutilated Security is surrendered to the Trustee, together with, in
proper cases, such security or indemnity as may be required by the Company or
the Trustee to save each of them harmless, the Company shall execute and the
Trustee shall authenticate and deliver a replacement Security of the same series
and date of maturity, if the Trustee's requirements are met.

        If there shall be delivered to the Company 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 agency of either of them harmless, then, in the absence of notice to the
Company or the Trustee that such Security has been acquired by a bona fide
purchaser, the Company shall execute and the Trustee shall authenticate and
deliver in lieu of any such destroyed, lost or stolen Security, a replacement
Security of the same series and principal amount, containing identical terms and
provisions 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 Company in its discretion may,
instead of issuing a new Security, pay such Security.

        Upon the issuance of any new Security under this Section, the Company
may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in relation thereto and any other
expenses (including the fees and expenses of the Trustee 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 Company, 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.

                                      -23-

        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 3.7    PAYMENT OF INTEREST; INTEREST RIGHTS PRESERVED

        Unless otherwise provided as contemplated by Section 3.1, interest, if
any, 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 at the office or agency
maintained for such purpose pursuant to Section 9.2; provided, however, that, at
the option of the Company, interest on any series of Securities that bear
interest may be paid (i) by check mailed to the address of the Person entitled
thereto as it shall appear on the Register of Holders of Securities of such
series or (ii) to the extent specified as contemplated by Section 3.1, by wire
transfer to an account maintained by the Person entitled thereto as specified in
the Register of Holders of Securities of such series.

        Unless otherwise provided as contemplated by Section 3.1, 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 Company, at its election in each case, as provided
in clause (1) or (2) below:

                (1) The Company 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 Company
        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 (1) 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 Company of such Special Record
        Date and, in the name and at the expense of the Company shall cause
        notice of the proposed payment of such Defaulted Interest and the
        Special Record Date therefor to be mailed, first-class postage prepaid,
        to each Holder of Securities of such series at his address as it appears
        in the Register, 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

                                      -24-
<PAGE>

        on such Special Record Date and shall no longer be payable pursuant to
        the following clause (2).

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

        Subject to the foregoing provisions of this Section and Section 3.5,
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 3.8    PERSONS DEEMED OWNERS

        Prior to due presentment of any Security for registration of transfer,
the Company, the Trustee and any agent of the Company 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, premium, if any,
and (subject to Section 3.7) interest on such Security and for all other
purposes whatsoever, whether or not such Security be overdue, and neither the
Company, the Trustee nor any agent of the Company or the Trustee shall be
affected by notice to the contrary.

SECTION 3.9    CANCELLATION

        The Company at any time may deliver Securities to the Trustee for
cancellation. The Registrar and any Paying Agent shall forward to the Trustee
any Securities surrendered to them for replacement, for registration of
transfer, or for exchange or payment. The Trustee shall cancel all Securities
surrendered for replacement, for registration of transfer, or for exchange,
payment, redemption or cancellation and may dispose of cancelled Securities and
issue a certificate of destruction to the Company. The Company may not issue new
Securities to replace Securities that it has paid or delivered to the Trustee
for cancellation, except as expressly permitted in the terms of Securities for
any particular series or as permitted pursuant to the terms of this Indenture.

SECTION 3.10   COMPUTATION OF INTEREST

        Except as otherwise specified as contemplated by Section 3.1 (i)
interest of any Securities that bear interest at a fixed rate shall be computed
on the basis of a 360-day year of twelve 30 day months and (ii) interest on any
Securities the bear interest at a variable rate shall be computed on the basis
of the actual number of days in an interest period divided by 360 or the actual
number of days in the year.

                                      -25-
<PAGE>

SECTION 3.11   CUSIP NUMBERS

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

                     SATISFACTION, DISCHARGE AND DEFEASANCE

SECTION 4.1    TERMINATION OF COMPANY'S OBLIGATIONS UNDER THE INDENTURE

        Except as otherwise provided as contemplated by Section 3.1, this
Indenture shall upon Company Request cease to be of further effect with respect
to Securities of or within any series (except as to any surviving rights of
registration of transfer or exchange of such Securities and replacement of such
Securities which may have been lost, stolen or mutilated as herein expressly
provided for) and the Trustee, at the expense of the Company, shall execute
proper instruments acknowledging satisfaction and discharge of this Indenture
with respect to such Securities when

               (1)    either

                        (A) all such Securities previously authenticated and
                delivered (other than (i) such Securities which have been
                destroyed, lost or stolen and which have been replaced or paid
                as provided in Section 3.6, and (ii) such Securities for whose
                payment money has theretofore been deposited in trust or
                segregated and held in trust by the Company and thereafter
                repaid to the Company or discharged from such trust, as provided
                in Section 9.3) have been delivered to the Trustee for
                cancellation; or

                        (B) all Securities of such series not theretofore
                delivered to the Trustee for cancellation

                                (i) have become due and payable, or

                                (ii) will become due and payable at their Stated
                        Maturity within one year, or

                                (iii) if redeemable at the option of the
                        Company, are to be called for redemption within one year
                        under arrangements satisfactory

                                      -26-
<PAGE>

                        to the Trustee for giving of notice of redemption by the
                        Trustee in the name, and at the expense, of the Company,

                and the Company, in the case of (i), (ii) or (iii) above, has
                irrevocably deposited or caused to be deposited with the Trustee
                as trust funds in trust for the purpose an amount sufficient to
                pay and discharge the entire indebtedness on such Securities not
                theretofore delivered to the Trustee for cancellation, for
                principal, premium, if any, and interest, with respect thereto,
                to the 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 Company has paid or caused to be paid all other sums
        payable hereunder by the Company; and

                (3) the Company has delivered to the Trustee an Officers'
        Certificate and an Opinion of Counsel, each stating that all conditions
        precedent herein provided for relating to the satisfaction and discharge
        of this Indenture as to such series have been complied with.

Notwithstanding the satisfaction and discharge of this Indenture, the obligation
of the Company to the Trustee and any predecessor Trustee under Section 6.8, the
obligations of the Company to any Authenticating Agent under Section 6.13 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 4.2 and
the last paragraph of Section 9.3 shall survive.

SECTION 4.2    APPLICATION OF TRUST FUNDS

        Subject to the provisions of the last paragraph of Section 9.3, all
money deposited with the Trustee pursuant to Section 4.1 shall be held in trust
and applied by it, in accordance with the provisions of the Securities and this
Indenture, to the payment, either directly or through any Paying Agent
(including the Company acting as its own Paying Agent) as the Trustee may
determine, to the Persons entitled thereto, of the principal, premium, if any,
and any interest for whose payment such money has been deposited with or
received by the Trustee, but such money need not be segregated from other funds
except to the extent required by law.

SECTION 4.3 APPLICABILITY OF DEFEASANCE PROVISIONS; COMPANY'S OPTION TO EFFECT
        DEFEASANCE OR COVENANT DEFEASANCE

        If pursuant to Section 3.1 provision is made for either or both of (i)
defeasance of the Securities of or within a series under Section 4.4 or (ii)
covenant defeasance of the Securities of or within a series under Section 4.5,
then the provisions of such Section or Sections, as the case may be, together
with the provisions of Sections 4.6 through 4.9 inclusive, with such
modifications thereto as may be specified pursuant to Section 3.1 with respect
to any Securities, shall be applicable to such Securities, and the Company may
at its option by Board Resolution, at any time, with respect to such Securities,
elect to have Section 4.4 (if

                                      -27-
<PAGE>

applicable) or Section 4.5 (if applicable) be applied to such Outstanding
Securities upon compliance with the conditions set forth below in this Article.

SECTION 4.4    DEFEASANCE AND DISCHARGE

        Upon the Company's exercise of the option specified in Section 4.3
applicable to this Section with respect to the Securities of or within a series,
the Company shall be deemed to have been discharged from its obligations with
respect to such Securities on the date the conditions set forth in Section 4.6
are satisfied (hereinafter "defeasance"). For this purpose, such defeasance
means that the Company shall be deemed to have paid and discharged the entire
indebtedness represented by such Securities which shall thereafter be deemed to
be "Outstanding" only for the purposes of Section 4.7 and the other Sections of
this Indenture referred to in clause (ii) of this Section, 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 Company,
shall on Company Order execute proper instruments acknowledging the same),
except the following which shall survive until otherwise terminated or
discharged hereunder: (i) the rights of Holders of such Securities to receive,
solely from the trust funds described in Section 4.6(a) and as more fully set
forth in such Section, payments in respect of the principal of, premium, if any,
and interest, if any, on such Securities when such payments are due; (ii) the
Company's obligations with respect to such Securities under Sections 3.5, 3.6,
9.2 and 9.3 and with respect to the payment of additional amounts, if any,
payable with respect to such Securities as specified pursuant to Section
3.1(b)(16); (iii) the rights, powers, trusts, duties and immunities of the
Trustee hereunder; and (iv) this Article 4. Subject to compliance with this
Article 4, the Company may exercise its option under this Section
notwithstanding the prior exercise of its option under Section 4.5 with respect
to such Securities. Following a defeasance, payment of such Securities may not
be accelerated because of an Event of Default.

SECTION 4.5    COVENANT DEFEASANCE

        Upon the Company's exercise of the option specified in Section 4.3
applicable to this Section with respect to any Securities of or within a series,
the Company shall be released from its obligations under Sections 7.1 and 9.4,
and, if specified pursuant to Section 3.1, its obligations under any other
covenant, with respect to such Securities on and after the date the conditions
set forth in Section 4.6 are satisfied (hereinafter, "covenant defeasance"), and
such Securities shall thereafter be deemed to be not "Outstanding" for the
purposes of any direction, waiver, consent or declaration or Act of Holders (and
the consequences of any thereof) in connection with Sections 7.1 and 9.4, or
such other covenant, but shall continue to be deemed "Outstanding" for all other
purposes hereunder. For this purpose, such covenant defeasance means that, with
respect to such Securities, the Company may omit to comply with and shall have
no liability in respect of any term, condition or limitation set forth in any
such Section or such other covenant, whether directly or indirectly, by reason
of any reference elsewhere herein to any such Section or such other covenant or
by reason of reference in any such Section or such other covenant to any other
provision herein or in any other document and such omission to comply shall not
constitute a Default or an Event of Default under Section 5.1(3) or 5.1(7)

                                      -28-
<PAGE>

or otherwise, as the case may be, but, except as specified above, the remainder
of this Indenture and such Securities shall be unaffected thereby.

SECTION 4.6    CONDITIONS TO DEFEASANCE OR COVENANT DEFEASANCE

        The following shall be the conditions to application of Section 4.4 or
Section 4.5 to any Securities of or within a series:

                (a) The Company shall have deposited or caused to be deposited
        irrevocably with the Trustee (or another trustee satisfying the
        requirements of Section 6.11 who shall agree to comply with, and shall
        be entitled to the benefits of, the provisions of Sections 4.3 through
        4.9 inclusive and the last paragraph of Section 9.3 applicable to the
        Trustee, for purposes of such Sections also a "Trustee") as trust funds
        in trust for the purpose of making the payments referred to in clauses
        (x) and (y) of this Section 4.6(a), specifically pledged as security
        for, and dedicated solely to, the benefit of the Holders of such
        Securities, with instructions to the Trustee as to the application
        thereof, (A) money in an amount, or (B) if Securities of such series are
        not subject to repayment at the option of Holders, Government
        Obligations which through the payment of interest and principal in
        respect thereof in accordance with their terms will provide, not later
        than one day before the due date of any payment referred to in clause
        (x) or (y) of this Section 4.6(a), money in an amount or (C) a
        combination thereof in an amount, sufficient, in the opinion of a
        nationally recognized firm of independent certified 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, (x) the principal of, premium, if any, and interest, if
        any, on such Securities on the Maturity of such principal or installment
        of principal or interest and (y) any mandatory sinking fund payments
        applicable to such Securities on the day on which such payments are due
        and payable in accordance with the terms of this Indenture and such
        Securities. Before such a deposit the Company may make arrangements
        satisfactory to the Trustee for the redemption of Securities at a future
        date or dates in accordance with Article 10 which shall be given effect
        in applying the foregoing.

                (b) Such defeasance or covenant defeasance shall not result in a
        breach or violation of, or constitute a Default or Event of Default
        under, this Indenture or result in a breach or violation of, or
        constitute a default under, any other material agreement or instrument
        to which the Company is a party or by which it is bound.

                (c) No Default or Event of Default under Section 5.1(5) or
        5.1(6) with respect to such Securities shall have occurred and be
        continuing during the period commencing on the date of such deposit and
        ending on the 91st day after such date (it being understood that this
        condition shall not be deemed satisfied until the expiration of such
        period).

                (d) In the case of an election under Section 4.4, the Company
        shall have delivered to the Trustee an Officers' Certificate and an
        Opinion of Counsel to the effect

                                      -29-
<PAGE>

        that (i) the Company has received from, or there has been published by,
        the Internal Revenue Service a ruling, or (ii) since the date of
        execution of this Indenture, there has been a change in the applicable
        Federal income tax law, in either case to the effect that, and based
        thereon such opinion shall confirm that, the Holders of such Securities
        will not recognize income, gain or loss for Federal income tax purposes
        as a result of such defeasance and will be subject to Federal income tax
        on the same amount and in the same manner and at the same times, as
        would have been the case if such deposit, defeasance and discharge had
        not occurred.

                (e) In the case of an election under Section 4.5, the Company
        shall have delivered to the Trustee an Opinion of Counsel to the effect
        that the Holders of such Securities will not recognize income, gain or
        loss for Federal income tax purposes as a result of such covenant
        defeasance and will be subject to Federal income tax on the same
        amounts, in the same manner and at the same times as would have been the
        case if such covenant defeasance had not occurred.

                (f) The Company shall have delivered to the Trustee an Officers'
        Certificate and an Opinion of Counsel, each stating that all conditions
        precedent to the defeasance under Section 4.4 or the covenant defeasance
        under Section 4.5 (as the case may be) have been complied with and an
        Opinion of Counsel to the effect that either (i) as a result of a
        deposit pursuant to subsection (a) above and the related exercise of the
        Company's option under Section 4.4 or Section 4.5 (as the case may be),
        registration is not required under the Investment Company Act of 1940,
        as amended, by the Company, with respect to the trust funds representing
        such deposit or by the trustee for such trust funds or (ii) all
        necessary registrations under said act have been effected.

                (g) Such defeasance or covenant defeasance shall be effected in
        compliance with any additional or substitute terms, conditions or
        limitations which may be imposed on the Company in connection therewith
        as contemplated by Section 3.1.

SECTION 4.7    DEPOSITED MONEY AND GOVERNMENT OBLIGATIONS TO BE HELD IN TRUST

        Subject to the provisions of the last paragraph of Section 9.3, all
money and Government Obligations (or other property as may be provided pursuant
to Section 3.1) (including the proceeds thereof) deposited with the Trustee
pursuant to Section 4.6 in respect of any Securities of any series 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
Paying Agent (including the Company 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, premium, if any, and interest, if
any, but such money need not be segregated from other funds except to the extent
required by law.

SECTION 4.8    TRANSFERS AND DISTRIBUTION AT COMPANY REQUEST

        To the extent permitted by the Financial Accounting Standards Board
Statement of Financial Accounting Standards No. 76, as amended or interpreted by
the Financial Accounting Standards Board from time to time, or any successor
thereto ("Standard No. 76"), or to the extent permitted by the Commission, the
Trustee shall, from time to time, take one or more of the following actions as
specified in a Company Request:

               (a) Retransfer, reassign and deliver to the Company any
        securities deposited with the Trustee pursuant to Section 4.6(a),
        provided that the Company shall in substitution therefor, simultaneously
        transfer, assign and deliver to the Trustee other Government Obligations
        appropriate to satisfy the Company's obligations in respect of the
        relevant Securities; and

               (b) The Trustee (and any Paying Agent) shall promptly pay to the
        Company upon Company Request any excess money or securities held by them
        at any time, including, without limitation, any assets deposited with
        the Trustee pursuant to Section 4.6(a) exceeding those necessary for the
        purposes of Section 4.6(a).

        The Trustee shall not take the actions described in subsections (a) and
(b) of this Section 4.8 unless it shall have first received a written report of
a nationally recognized independent public accounting firm, (i) expressing their
opinion that the contemplated action is permitted by Standard No. 76 or the
Commission, for transactions accounted for as extinguishment of debt under the
circumstances described in paragraph 3.c of Standard No. 76 or any successor
provision and (ii) verifying the accuracy, after giving effect to such action or
actions, of the computations which demonstrate that the amounts remaining to be
earned on the Government Obligations deposited with the Trustee pursuant to
Section 4.6(a) will be sufficient for purposes of Section 4.6(a).

SECTION 5.1    EVENTS OF DEFAULT

        An "Event of Default" occurs with respect to the Securities of any
series if (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):

               (1) the Company defaults in the payment of interest on any
        Security of that series or any additional amount payable with respect to
        any Security of that series as specified pursuant to Section 3.1(b)(14)
        when the same becomes due and payable and such default continues for a
        period of 90 days;

                                      -31-
<PAGE>

                (2) the Company defaults in the payment of the principal of or
        any premium on any Security of that series when the same becomes due and
        payable at its Maturity or on redemption or otherwise, or in the payment
        of a mandatory sinking fund payment when and as due by the terms of the
        Securities of that series, and in each case such default continues for a
        period of ten days;

                (3) the Company defaults in the performance of, or breaches, any
        covenant or warranty of the Company in this Indenture with respect to
        any Security of that series (other than a covenant or warranty a default
        in whose performance or whose breach is elsewhere in this Section
        specifically dealt with), and such default or breach continues for a
        period of 60 days after there has been given, by registered or certified
        mail, to the Company by the Trustee or to the Company 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;

        the Company; and the order or decree remains unstayed and in effect for
        90 consecutive days; or

                (6) any other Event of Default provided as contemplated by
        Section 3.1 with respect to Securities of that series.

similar federal or state law for the relief of debtors. The term "Custodian"
means any receiver, trustee, assignee, liquidator or similar official under any

SECTION 5.2    ACCELERATION, RESCISSION AND ANNULMENT

        If an Event of Default with respect to the Securities of any series at
the time Outstanding occurs and is continuing, the Trustee or the Holders of at
least 25% in aggregate principal amount of all of the outstanding Securities of
that series, by written notice to the Company (and, if given by the Holders, to
the Trustee), may declare the principal (or, if the Securities of that series
are Original Issue Discount Securities or Indexed Securities, such portion of
the principal amount as may be specified in the terms of that series) of all the
Securities of that series to be due and payable and upon any such declaration
such principal

                                      -32-
<PAGE>

(or, in the case of original Issue Discount Securities or Indexed Securities,
such specified amount) shall be 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 aggregate principal amount of the
outstanding Securities of that series, by written notice to the Trustee, may
rescind and annul such declaration and its consequences if all existing Defaults
and Events of Default with respect to Securities of that series, other than the
nonpayment 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 5.7. No such rescission shall affect any subsequent default
or impair any right consequent thereon.

SECTION 5.3    COLLECTION OF INDEBTEDNESS AND SUITS FOR ENFORCEMENT BY TRUSTEE

        The Company 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 90 days, or

               (2) default is made in the payment of the principal of (or
        premium, if any, on) any Security at the Maturity thereof and such
        default continues for a period of 10 days,

the Company 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, premium, if any, and interest and, to the extent that
payment of such interest shall be legally enforceable, interest on any overdue
principal, premium, if any, 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 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 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 5.4    TRUSTEE MAY FILE PROOFS OF CLAIM

        The Trustee may file such proofs of claim and other papers or documents
as may be necessary or advisable in order to have the claims of the Trustee and
the Holders of Securities allowed in any judicial proceedings relating to the
Company, its creditors or its property.

                                      -33-

SECTION 5.5    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.

SECTION 5.6    DELAY OR OMISSION NOT WAIVER

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

SECTION 5.7    WAIVER OF PAST DEFAULTS

        The Holders of a majority in aggregate principal amount of Outstanding
Securities of any series by notice to the Trustee may waive on behalf of the
Holders of all Securities of such series a past Default or Event of Default with
respect to that series and its consequences except (i) a Default or Event of
Default in the payment of the principal of, premium, if any, or interest on any
Security of such series or (ii) in respect of a covenant or provision hereof
which pursuant to Section 8.2 cannot be amended or modified without the consent
of the Holder of each outstanding Security of such series adversely affected.
Upon any such waiver, such Default shall cease to exist, and any Event of
Default arising therefrom shall be deemed to have been cured, for every purpose
of this Indenture.

SECTION 5.8    CONTROL BY MAJORITY

        The Holders of a majority in aggregate principal amount of the
Outstanding Securities of each series affected (with each such series voting as
a class) 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 it with respect to Securities of that series; provided,
however, that (i) the Trustee may refuse to follow any direction that conflicts
with law or this Indenture, (ii) the Trustee may refuse to follow any direction
that is unduly prejudicial to the rights of the Holders of Securities of such
series not consenting, or that would in the good-faith judgment of the Trustee
have a substantial likelihood of involving the Trustee in personal liability and
(iii) the Trustee may take any other action deemed proper by the Trustee which
is not inconsistent with such direction.

SECTION 5.9    LIMITATION ON SUITS BY HOLDERS

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

                                      -34-
<PAGE>

               (2) the Holders of at least 25% in aggregate principal amount of
        the Outstanding Securities of that series have made a 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 indemnity
        satisfactory to the Trustee against any loss, liability or expense to
        be, or which may be, incurred by the Trustee in pursuing the remedy;

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

               (5) during such 60-day period, the Holders of a majority in
        aggregate principal amount of the Outstanding Securities of that series
        has not given to the Trustee a direction inconsistent with such written
        request.

        No one or more 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.

such payment on or after such respective dates, shall not be impaired or
affected without the consent of such Holder.

thereon of the payment if only partially paid and upon surrender thereof if
fully paid:

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

SECTION 5.12   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 Company, 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 5.13   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 3.6, no right or remedy herein conferred upon or reserved to the Trustee
or 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.

                                   THE TRUSTEE

SECTION 6.1    CERTAIN DUTIES AND RESPONSIBILITIES

        duties as are specifically set forth in this Indenture, and no implied
        covenants or obligations shall be read into this Indenture against the
        Trustee; and

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

        (b) In case an Event of Default has occurred and is continuing with
respect to the Securities of any series, the Trustee shall exercise such of the
rights and powers vested in it by this Indenture with respect to the Securities
of such series, and use the same degree of care and

                                      -36-
<PAGE>

skill in their exercise, as a prudent person would exercise or use under the
circumstances in the conduct of his own affairs.

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

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

                (2) the Trustee shall not be liable for any error of judgment
        made in good faith by a Responsible Officer, unless it shall be proved

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

        (d) 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.

        (e) 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.

        other evidence be herein specifically prescribed) may, in the absence of
        bad faith on its part, rely upon an Officers' Certificate.

               (d) The Trustee may consult with counsel of its selection and the
        written advice of such counsel or any Opinion of Counsel shall be full

        instrument, opinion, report, notice, request, direction, consent, order,
        bond, debenture, note 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 to
        examine the books, records and premises of the Company, personally or by
        agent or attorney.

        funds or otherwise incur any financial liability in the performance of
        any of its duties hereunder, or in the exercise of its rights or powers,

with an Event of Default specified in Section 5.1(5) or Section 5.1(6), the

        (c) The Holders of a majority in aggregate principal amount of the
Outstanding Securities of any series may remove the Trustee with respect to that
series by so notifying the Trustee and the Company and may appoint a successor
Trustee for such series with the Company's consent.

        (d)    If at any time:

               (1) the Trustee fails to comply with Section 310(b) of the Trust
        Indenture Act after written request therefor by the Company 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 310(a)
        of the Trust Indenture Act and shall fail to resign after written
        request therefor by the Company or by any Holder of a Security who has
        been a bona fide Holder of a Security for at least six months; or

               (3) the Trustee becomes incapable of acting, is adjudged a
        bankrupt or an insolvent or a receiver or public officer takes charge of
        the Trustee or its property or affairs for the purpose of
        rehabilitation, conservation or liquidation, then, in any such case, (i)
        the Company by or pursuant to a Board Resolution may remove the Trustee
        with respect to all Securities, or (ii) subject to Section 315(e) of the
        Trust Indenture Act, any Holder who has been a bona fide Holder of a
        Security for at least six months may, on behalf of himself and all other
        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.

        (e) If the Trustee resigns or is removed or if a vacancy exists in the
office of Trustee for any reason, with respect to Securities of one or more
series, the Company, by or pursuant to Board Resolution, shall promptly appoint
a successor Trustee 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 6.11. 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
Company 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 6.11, become the successor Trustee with
respect to the Securities of such series and to that extent supersede the
successor Trustee appointed by the Company. If no successor Trustee with respect
to the Securities of any series shall have been so appointed by the Company or
the Holders and accepted appointment in the manner required by Section 6.11,

                                      -41-
<PAGE>

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.

SECTION 6.11   ACCEPTANCE OF APPOINTMENT BY SUCCESSOR

        (a) In case of the appointment hereunder of a successor Trustee with
respect to all Securities, every such successor Trustee shall execute,
acknowledge and deliver to the Company and to the retiring Trustee an instrument
accepting such appointment. Thereupon, the resignation or removal of the
retiring Trustee shall become effective, and the successor Trustee, without
further act, deed or conveyance, shall become vested with all the rights, powers
and duties of the retiring Trustee; but, on the request of the Company 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.

        (b) In case of the appointment hereunder of a successor Trustee with
respect to the Securities of one or more (but not all) series, the Company, the
retiring Trustee and such successor Trustee shall execute and deliver an
indenture supplemental hereto wherein such successor Trustee shall accept such
appointment and which (i) shall contain such provisions as shall be necessary or
desirable to transfer and confirm to, and to vest in, such 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, (ii) 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 (iii) 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 the Securities of that or those series
to which the appointment of such successor Trustee relates; but, on request of
the Company 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.

                                      -42-
<PAGE>

        (c) Upon request of any such successor Trustee, the Company 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 paragraph (a) or (b) of this Section, as the case may be.

        (d) No successor Trustee shall accept its appointment unless at the time
of such acceptance such successor Trustee shall be qualified and eligible under
the Trust Indenture Act.

        (e) The Company 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 in the
manner provided for notices to the Holders of Securities in Section 1.6. 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 6.12   ELIGIBILITY; DISQUALIFICATION

        There shall at all times be a Trustee hereunder which shall be eligible
to act as Trustee under Section 310(a)(1) of the Trust Indenture Act and shall
have a combined capital and surplus of at least $100 million. If such
corporation publishes reports of condition at least annually, pursuant to law or
the requirements of Federal, State Territorial or District of Columbia
supervising or examining authority, then for the purposes of this Section, the
combined capital and surplus of such corporation 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 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 6.13   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 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 6.14   APPOINTMENT OF AUTHENTICATING AGENT

        The Trustee may appoint an Authenticating Agent or Agents with respect
to one or more series of Securities which shall be authorized to act on behalf
of the Trustee to

                                      -43-
<PAGE>

authenticate Securities of such series issued upon original issue exchange,
registration of transfer or partial redemption thereof, 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. Any such appointment shall be evidenced by an instrument in writing
signed by a Responsible Officer of the Trustee, a copy of which instrument shall
be promptly furnished to the Company. Wherever reference is made in this
Indenture to the authenticating 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 be
acceptable to the Company and, except as may otherwise be provided pursuant to
Section 3.1, shall at all times be a bank or trust company or corporation
organized and doing business and in good standing under the laws of the United
States of America or of any State or the District of Columbia, authorized under
such laws to act as Authenticating Agent, having a combined capital and surplus
of not less than $10 million and subject to supervision or examination by
Federal or State authorities. If such Authenticating Agent publishes reports of
condition at least annually, pursuant to law or the requirements of the
aforesaid 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. In case 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 the corporate agency or
corporate trust business of an Authenticating Agent, shall continue to be an
Authenticating Agent, provided, such corporation shall be otherwise eligible
under this Section, without the execution or filing of any paper or further act
on the part of the Trustee or the Authenticating Agent.

        An Authenticating Agent for any series of Securities may at any time
resign by giving written notice of resignation to the Trustee for such series
and to the Company. The Trustee for any series of Securities may at any time
terminate the agency of an Authenticating Agent by giving written notice of
termination to such Authenticating Agent and to the Company. 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 for such series may appoint a successor
Authenticating Agent which shall be acceptable to the Company and shall give
notice of such appointment to all Holders of Securities of the series with
respect to which such Authenticating Agent will serve in the manner set forth in
Section 1.6. 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 herein. No successor Authenticating Agent shall be
appointed unless eligible under the provisions of this Section.

                                      -44-
<PAGE>

        The Company agrees to pay to each Authenticating Agent from time to time
reasonable compensation, including reimbursement of its reasonable expenses 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 or in lieu of the Trustee's certificate of authentication, an
alternate certificate of authentication substantially in the following form:

        This is one of the Securities of a series issued under the
within-mentioned Indenture.

        Any application by the Trustee for written instructions from the Company
may, at the option of the Trustee, set forth in writing any action proposed to
be taken or omitted by the Trustee under this Indenture and the date on and/or
after which such action shall be taken or such omission shall be effective. The
Trustee shall not be liable for any action taken by, or omission of, the Trustee
in accordance with a proposal included in such application on or after the date
specified in such application (which date shall not be less than fifteen
Business Days after the date any officer of the Company actually receives such
application, unless any such officer shall have consented in writing to any
earlier date) unless prior to taking any such action (or the effective date in
the case of an omission), the Trustee shall have received written instructions
in response to such application specifying the action to be taken or omitted.

all of its assets to any person, firm or corporation, if (i) (A) in the case of
a merger or consolidation, the Company is the surviving corporation or (B) in
the case of a merger or consolidation where the Company is not the surviving
corporation and in the case of any such sale, conveyance or other disposition,

                                      -45-
<PAGE>

the successor or acquiring corporation is a corporation organized and existing
under the laws of the United States or a State thereof and such corporation
expressly assumes by supplemental indenture all of the obligations of the
Company under the Securities and under this Indenture, (ii) immediately
thereafter, giving effect to such merger or consolidation, or such sale,
conveyance, transfer or other disposition, no Default or Event of Default shall
have occurred and be continuing and (iii) the company has delivered to the
Trustee an Officers' Certificate and an Opinion of Counsel each stating that
such merger or consolidation, or such sale, conveyance, transfer or other
disposition, complies with this Article and that all conditions precedent herein
provided for relating to such transaction have been complied with. In the event
of the assumption by a successor corporation of the obligations of the Company
as provided in clause (i)(B) of the immediately preceding sentence, such
successor corporation shall succeed to and be substituted for the Company
hereunder and under the Securities and all such obligations of the Company shall
terminate.

SECTION 7.2    NO LIMITATIONS

        Nothing contained in this Indenture or in any of the Securities shall
prevent the Company from merging into itself any other corporation or entity
(whether or not affiliated with the Company) or acquiring by purchase or
otherwise all or any part of the property of any other corporation or entity
(whether or not affiliated with the Company).

SECTION 8.1    SUPPLEMENTAL INDENTURES WITHOUT CONSENT OF HOLDERS

        Without the consent of any Holders, the Company, when authorized by a
Board Resolution, and the Trustee, at any time and from time to time, may enter
into indentures supplemental hereto, in form reasonably satisfactory to the
Trustee, for any of the following purposes:

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

                (2) to add to the covenants of the Company 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 Company; or

                (3) to add any additional Events of Default with respect to all
        or any series of Securities; or

                                      -46-
<PAGE>

                (4) to add to or change any of the provisions of this Indenture
        to such extent as shall be necessary to 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 global form; or

                (5) to add to, change or eliminate any of the provisions of this
        Indenture, provided that any such addition, change or elimination shall
        become effective only when there is no Security Outstanding of any
        series created prior to the execution of such supplemental indenture
        which is entitled to the benefit of such provision; or

                (6) to secure the Securities; or

                (7) to establish the form or terms of Securities of any series
        as permitted by Sections 2.1 and 3.2; 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 6.10; or

                (9) to correct or supplement any provision herein which may be
        inconsistent with any other provision herein or to make any other

        Indenture, provided such action shall not adversely affect the interests
        of the Holders of Securities of any series in any material respect, or
        to cure any ambiguity or correct any mistake.

SECTION 8.2    WITH CONSENT OF HOLDERS

        With the written consent of the Holders of a majority of the aggregate
principal amount of the Outstanding Securities of each series adversely affected
by such supplemental indenture, the Company and the Trustee may enter into an
indenture or indentures supplemental hereto to add any provisions to or to
change or eliminate any provisions of this Indenture or of any other indenture
supplemental hereto or to modify the rights of the Holders of Securities of each
such series; provided, however, that without the consent of the Holder of each
Outstanding Security affected thereby, an amendment under this Section may not:

               (1) change the Stated Maturity of the principal of, or any
        installment of principal of or interest on, any 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 an Original Issue Discount Security that would be due and
        payable upon a declaration of acceleration of the Maturity thereof
        pursuant to Section 5.2, or change the coin or currency in which, any
        Securities or any premium or the 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);

                (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

        Indenture or certain defaults hereunder and their consequences) provided
        for in this Indenture;

                (3) change any obligation of the Company to maintain an office
        or agency in the places and for the purposes specified in Section 9.2;
        or

                (4) make any change in Section 5.7 or this 8.2(a) except to
        increase any percentage or to provide that certain other provisions of
        this Indenture cannot be modified or waived with the consent of the
        Holders of each Outstanding Security affected thereby.

        A supplemental indenture that 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 that 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 is not necessary under this Section 8.2 for the Holders to consent to
the particular form of any proposed supplemental indenture, but it is sufficient
if they consent to the substance thereof.

SECTION 8.3    COMPLIANCE WITH TRUST INDENTURE ACT

        Every supplemental indenture executed pursuant to this Article shall
comply with the requirements of the Trust Indenture Act as then in effect.

SECTION 8.4    EXECUTION OF SUPPLEMENTAL INDENTURES

        In executing, or accepting the additional trusts created by, any
supplemental indenture permitted by this Article or the modification thereby of
the trusts created by this Indenture, the Trustee shall be entitled to receive,
and 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.

SECTION 8.5    EFFECT OF SUPPLEMENTAL INDENTURES

        Upon the execution of any supplemental indenture under this article,
this Indenture shall be modified in accordance therewith, and such supplemental

of Securities theretofore or thereafter authenticated and delivered hereunder
shall be bound thereby.

SECTION 8.6    REFERENCE IN SECURITIES TO SUPPLEMENTAL INDENTURES

        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 Company shall so
determine, new Securities of any series so modified as to conform, in the
opinion of the Trustee and the Company, to any such supplemental indenture may
be prepared and executed by the Company and authenticated and delivered by the
Trustee in exchange for Outstanding Securities.

                                    COVENANTS

SECTION 9.1    PAYMENT OF PRINCIPAL, PREMIUM, IF ANY, AND INTEREST

        The Company covenants and agrees for the benefit of the Holders of each
series of Securities that it will duly and punctually pay the principal of,
premium, if any, and interest on the Securities of that series in accordance
with the terms of the Securities of such series and this Indenture. An
installment of principal or interest shall be considered paid on the date it is
due if the Trustee or Paying Agent holds on that date money designated for and
sufficient to pay the installment.

SECTION 9.2    MAINTENANCE OF OFFICE OR AGENCY

        The Company 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 Company in respect of the Securities of that series and this Indenture
may be served. The Company will give prompt written notice to the Trustee of the
location, and any change in the location, of any such office or agency. If at
any time the Company 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 Company hereby appoints the
Trustee as its agent to receive all such presentations, surrenders, notices and
demands.

        The Company 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 Company of its obligation to maintain an office
or agency in each Place of Payment for Securities of any series for such
purposes. The Company 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.

                                      -49-
<PAGE>

        Unless otherwise specified as contemplated by Section 3.1, the Trustee
shall initially serve as Paying Agent.

SECTION 9.3    MONEY FOR SECURITIES TO BE HELD IN TRUST; UNCLAIMED MONEY

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

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

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

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

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

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

        Any money deposited with the Trustee or any Paying Agent, or then held
by the Company, in trust for the payment of any principal, premium or interest
on any Security of any series and remaining unclaimed for two years after such
principal, premium, if any, or interest has become due and payable shall be paid
to the Company on Company Request, or (if then held by the Company) shall be
discharged from such trust; and the Holder of such Security shall thereafter, as
an unsecured general creditor, look only to the Company for payment thereof, and
all liability of the Trustee or such Paying Agent with respect to such trust
money, and all liability of the Company as trustee thereof, shall thereupon
cease; provided, however, that the Trustee or such Paying Agent, before being
required to make any such repayment, may

                                      -50-

specified therein, which shall not be less than 30 days from the date of such
publication, any unclaimed balance of such money then remaining will be repaid
to the Company.

                                   REDEMPTION

SECTION 10.1   APPLICABILITY OF ARTICLE

        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 3.1 for Securities of any series)
in accordance with this Article.

SECTION 10.2   ELECTION TO REDEEM; NOTICE TO TRUSTEE

        The election of the Company to redeem any Securities shall be evidenced
by or pursuant to a Board Resolution or any Officers' Certificate. In the case
of any redemption at the election of the Company of less than all the
Securities, if any, of any series, the Company shall, at least 60 days prior to
the Redemption Date fixed by the Company (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 (i) prior to the

                                      -53-
<PAGE>

expiration of any restriction on such redemption provided in the terms of such
Securities or elsewhere in this Indenture or (ii) pursuant to an election of the
Company which is subject to a condition specified in the terms of such
Securities, the Company shall furnish the Trustee with an Officers' Certificate
evidencing compliance with such restriction or condition.

SECTION 10.3   SELECTION OF SECURITIES TO BE REDEEMED

        Unless otherwise specified as contemplated by Section 3.1, if less than
all the Securities of a series with the same original issue date, interest rate
and Stated Maturity are to be redeemed, the Trustee, not more than 45 days prior
to the redemption date, shall select the Securities of the series to be redeemed
in such manner as the Trustee shall deem fair and appropriate. The Trustee shall
make the selection from Securities of the series that are Outstanding and that
have not previously been called for redemption and may provide for the selection
for redemption of portions (equal to the minimum authorized denomination for
Securities of that series or any integral multiple thereof) of the principal
amount of Securities of such series of a denomination larger than the minimum
authorized denomination for Securities of that series. The Trustee shall
promptly notify the Company in writing of the Securities selected by the Trustee
for redemption and, in the case of any Securities selected for partial
redemption, the principal amount thereof to be redeemed.

        For 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 10.4   NOTICE OF REDEMPTION

        Unless otherwise specified as contemplated by Section 3.1, notice of
redemption shall be given in the manner provided in Section 1.6 not less than 30
days nor more than 60 days prior to the Redemption Date to the Holders of the
Securities to be redeemed.

        All notices of redemption shall state:

               (1)    the Redemption Date;

               (2)    the Redemption Price;

               (3) if fewer than all the Outstanding Securities of a series are
        to be redeemed, the identification (and, in the case of partial
        redemption, the principal amounts) of the particular Security or
        Securities to be redeemed;

               (4) in case any Security is to be redeemed in part only, the
        notice which relates to such Security shall state that on and after the
        Redemption Date, upon surrender of such Security, the holder will
        receive, without a charge, a new Security or Securities of authorized
        denominations for the principal amount thereof remaining unredeemed;

                                      -54-
<PAGE>

                (5) the Place or Places of Payment where such Securities
        maturing after the Redemption Date, are to be surrendered for payment
        for the Redemption Price;

                (6) that Securities of the series called for redemption must be
        surrendered to the Paying Agent to collect the redemption price;

                (7) that, on the Redemption Date, the Redemption Price will
        become due and payable upon each such Security, or the portion thereof,
        to be redeemed and, if applicable, that interest thereon will cease to
        accrue on and after said date;

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

                (9) CUSIP number.

        Notice of redemption of Securities to be redeemed shall be given by the
Company or, at the Company's request, by the Trustee in the name and at the
expense of the Company.

SECTION 10.5   DEPOSIT OF REDEMPTION PRICE

        On or prior to any Redemption Date, the Company shall deposit with the
Trustee or with a Paying Agent (or, if the Company is acting as its own Paying
Agent, segregate and hold in trust as provided in Section 9.3) an amount of
money sufficient to pay on the Redemption Date the Redemption Price of, and
(unless the Redemption Date shall be an Interest Payment Date) interest accrued
to the Redemption Date on, all Securities or portions thereof which are to be
redeemed on that date.

        Unless any Security by its terms prohibits any sinking fund payment
obligation from being satisfied by delivering and crediting Securities
(including Securities redeemed otherwise than through a sinking fund), the
Company may deliver such Securities to the Trustee for crediting against such
payment obligation in accordance with the terms of such Securities and this
Indenture.

SECTION 10.6   SECURITIES PAYABLE ON REDEMPTION DATE

        Notice of redemption having been given as aforesaid, the Securities 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 the
Company shall default in the payment of the Redemption Price and accrued
interest) such Securities shall cease to bear interest. Except as provided in
the next succeeding paragraph, upon surrender of any such Security for
redemption in accordance with said notice, such Security shall be paid by the
Company at the Redemption Price, together with accrued interest to the
Redemption Date; provided, however, that, unless otherwise specified as
contemplated by Section 3.1, installments of interest on Securities whose Stated
Maturity is prior to the Redemption Date shall 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 3.7.

                                      -55-
<PAGE>

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

SECTION 10.7   SECURITIES REDEEMED IN PART

        Upon surrender of a Security that is redeemed in part at any Place of
Payment therefor (with, if the Company or the Trustee so required, due
endorsement by, or a written instrument of transfer in form satisfactory to the
Company and the Trustee duly executed by, the Holder thereof or his attorney
duly authorized in writing), the Company shall execute and the Trustee shall
authenticate and deliver to the Holder of that Security, without service charge,
a new Security or Securities of the same series, the same form and the same
Maturity in any authorized denomination equal in aggregate principal amount to
the unredeemed portion of the principal of the Security surrendered.

                                  SINKING FUNDS

SECTION 11.1   APPLICABILITY OF ARTICLE

        The provisions of this Article shall be applicable to any sinking fund
for the retirement of Securities of a series except as otherwise specified as
contemplated by Section 3.1 for Securities of such series.

        The minimum amount of any sinking fund payment provided for by the terms
of Securities of any series is herein referred to as a "mandatory sinking fund
payment," and any payment in excess of such minimum amount provided for by the
terms of Securities of any series is herein referred to as an "optional sinking
fund payment." If provided for by the terms of Securities of any series, the
cash amount of any sinking fund payment may be subject to reduction as provided
in Section 11.2. Each sinking fund payment shall be applied to the redemption of
Securities of any series as provided for by the terms of Securities of such
series.

SECTION 11.2   SATISFACTION OF SINKING FUND PAYMENTS WITH SECURITIES

        The Company (i) may deliver Outstanding Securities of a series (other
than any previously called for redemption) and (ii) may apply as a credit
Securities of a series which have been redeemed either at the election of the
Company 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 the Securities of such series required to be made
pursuant to the terms of such Securities as provided for by the terms of such
series; provided that such Securities have not been previously so credited. Such
Securities shall be received and credited for such purpose by the Trustee at the
Redemption Price specified in such Securities for redemption through operation
of the sinking fund and the amount of such sinking fund payment shall be reduced
accordingly.

        Not less than 60 days prior to each sinking fund payment date for any
series of Securities, the Company will deliver to the Trustee an Officers'
Certificate specifying the amount of the next ensuing sinking fund payment for
that series pursuant to the terms of that series, 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 of that series
pursuant to Section 11.2 and will also deliver to the Trustee any Securities to
be so delivered. Not less than 30 days before 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 10.3 and cause notice of
the redemption thereof to be given in the name of and at the expense of the
Company in the manner provided in Section 10.4. Such notice having been duly
given, the redemption of such Securities shall be made upon the terms and in the
manner stated in Sections 10.6 and 10.7.
