(5)         the place or places where and the manner in which, the principal of
            and any interest on Securities of the series shall be payable, if
            other than as provided in Section 3.2;

(6)         the right, if any, of the Issuer to redeem Securities, in whole or
            in part, at its option and the period or periods within which, or
            the date or dates on which, the price or prices at which and any
            terms and conditions upon which Securities of the series may be so
            redeemed, pursuant to any sinking fund or otherwise;

(7)         the obligation, if any, of the Issuer to redeem, purchase or repay
            Securities of the series pursuant to any mandatory redemption,
            sinking fund or analogous provisions or at the option of a Holder
            thereof, and the price or prices at which and the period or periods
            within which or the date or dates on which and any terms and
            conditions upon which Securities of the series shall be redeemed,
            purchased or repaid, in whole or in part, pursuant to such
            obligation;

(8)         if other than denominations of $1,000 and any integral multiple
            thereof;

(9)         the percentage of the principal amount at which the Securities will
            be issued, and, if other than the principal amount thereof, the
            portion of the principal amount of Securities of the series which
            shall be payable upon declaration of acceleration of the maturity
            thereof;


                                       5




(10)        whether the Securities of the series will be issuable as
            unregistered securities (with or without coupons), any restrictions
            applicable to the offer, sale or delivery of unregistered securities
            or the payment of interest thereon and, the terms upon which
            unregistered securities of any series may be exchanged for
            Registered Securities of such series and vice versa;

(11)        whether and under what circumstances the Issuer will pay additional
            amounts on the Securities of the series held by a person who is not
            a U.S. person in respect of any tax, assessment or governmental
            charge withheld or deducted and, if so, whether the Issuer will have
            the option to redeem the Securities of the series rather than pay
            such additional amounts;

(12)        if the Securities of the series are to be issuable in definitive
            form (whether upon original issue or upon exchange of a temporary
            Security of such series) only upon receipt of certain certificates
            or other documents or satisfaction of other conditions, the form and
            terms of such certificates, documents or conditions;

(13)        any trustees, depositories, authenticating or paying agents,
            transfer agents or registrars of any other agents with respect to
            the Securities of such series;

(14)        any deletion from modification of or addition to the Events of
            Default or covenants with respect to the Securities of such series;
            and

(15)        any other terms of the series (which terms shall not be inconsistent
            with the provisions of this Indenture).

         All Securities of any one series shall be substantially identical,
except in the case of Registered Securities as to denomination and except as may
otherwise be provided by or pursuant to the Board Resolution or Officer's
Certificate referred to above. All Securities of any one series need not be
issued at the same time and may be issued from time to time, consistent with the
terms of this Indenture, if so provided by or pursuant to such Board Resolution
or such Officer's Certificate.

          SECTION 2.4. Authentication And Delivery Of Securities. The Issuer may
deliver Securities of any series executed by the Issuer to the Trustee for
authentication together with the applicable documents referred to below in this
Section 2.4, and the Trustee shall thereupon authenticate and deliver such
Securities to or upon the order of the Issuer (contained in the Issuer Order
referred to below in this Section) or pursuant to such procedures acceptable to
the Trustee and to such recipients as may be specified from time to time by an
Issuer Order. The maturity date, original issue date, interest rate and any
other terms of the Securities of such series shall be determined by or pursuant
to such Issuer Order and procedures. If provided for in such procedures, such
Issuer Order may authorize authentication and delivery pursuant to oral or
electronic instructions from the Issuer or its duly authorized agent or agents,
which instructions, if oral, shall be promptly confirmed in writing. In
authenticating such Securities and accepting the additional responsibilities
under this Indenture in relation to such Securities, the Trustee shall be
entitled to receive (in the case of subparagraphs (2), (3) and (4) below only at
or before the time of the first request of the Issuer to the Trustee to
authenticate Securities of such series) and (subject to Section 6.1) shall be
fully protected in relying upon, the following enumerated documents unless and
until such documents have been superseded or revoked:

(1)       an Issuer Order requesting such authentication and setting forth
          delivery instructions if the Securities are not to be delivered to the
          Issuer, PROVIDED that, with respect to Securities of a series subject
          to a Periodic Offering, (a) such Issuer Order may be delivered by the
          Issuer to the Trustee prior to the delivery to the Trustee of such
          Securities for authentication and delivery, (b) the Trustee shall
          authenticate and deliver Securities of such series for original issue
          from time to time, in an aggregate principal amount not exceeding the
          aggregate principal amount established for such series, pursuant to an
          Issuer Order or pursuant to procedures acceptable to the Trustee as
          may be specified from time to time by an Issuer Order, (c) the
          maturity date or dates, original issue date or dates, interest rate or
          rates and any other terms of Securities of such series shall be
          determined by an Issuer Order or pursuant to such procedures and (d)
          if provided for in such procedures, such Issuer Order may authorize
          authentication and delivery



                                       6


          pursuant to oral or electronic instructions from the Issuer or its
          duly authorized agent or agents, which instructions, if oral, shall
          be promptly confirmed in writing;

(2)       any Board Resolution and/or Officer's Certificate referred to in
          Section 2.1 and 2.3 by or pursuant to which the forms and terms of the
          Securities were established;

(3)       an Officer's Certificate setting forth the form or forms and terms of
          the Securities stating that the form or forms and terms of the
          Securities have been established pursuant to Sections 2.1 and 2.3 and
          comply with this Indenture, and covering such other matters as the
          Trustee may reasonably request; and

(4)       At the option of the Issuer, either one or more Opinions of Counsel,
          or a letter addressed to the Trustee permitting it to rely on one or
          more Opinions of Counsel, substantially to the effect that:

          (a)       the form or forms of the Securities have been duly
                    authorized and established in conformity with the provisions
                    of this Indenture;

          (b)       in the case of an underwritten offering, the terms of the
                    Securities have been duly authorized and established in
                    conformity with the provisions of this Indenture, and, in
                    the case of an offering that is not underwritten, certain
                    terms of the Securities have been established pursuant to a
                    Board Resolution or an Officer's Certificate in accordance
                    with this Indenture, and when such other terms as are to be
                    established pursuant to procedures set forth in an Issuer
                    Order shall have been established, all such terms will have
                    been duly authorized by the Issuer and will have been
                    established in conformity with the provisions of this
                    Indenture; and

          (c)       such Securities when executed by the Issuer and
                    authenticated by the Trustee in accordance with the
                    provisions of this Indenture and delivered to and duly paid
                    for by the purchasers thereof, and subject to any conditions
                    specified in such Opinion of Counsel, will have been duly
                    issued under this Indenture, will be entitled to the
                    benefits of this Indenture, and will be valid and binding
                    obligations of the Issuer, enforceable in accordance with
                    their respective terms except as the enforceability thereof
                    may be limited by (i) bankruptcy, insolvency,
                    reorganization, liquidation, moratorium, fraudulent transfer
                    or similar laws affecting creditors' rights generally, (ii)
                    rights of acceleration, if any, and (iii) the availability
                    of equitable remedies may be limited by equitable principles
                    of general applicability and such counsel need express no
                    opinion with regard to the enforceability of Section 6.6.

         In rendering such opinions, any counsel may qualify any opinions as to
enforceability by stating that such enforceability may be limited by bankruptcy,
insolvency, reorganization, liquidation, moratorium, fraudulent transfer and
other similar laws affecting the rights and remedies of creditors and is subject
to general principles of equity (regardless of whether such enforceability is
considered in a proceeding in equity or at law). Such counsel may rely upon
opinions of other counsel (copies of which shall be delivered to the Trustee)
reasonably satisfactory to the Trustee, in which case the opinion shall state
that such counsel believes he and the Trustee are entitled so to rely. Such
counsel may also state that, insofar as such opinion involves factual matters,
he has relied, to the extent he deems proper, upon certificates of officers of
the Issuer and its Subsidiaries and certificates of public officials.

         The Trustee shall have the right to decline to authenticate and deliver
any Securities under this Section 2.4 if the Trustee, being advised by counsel,
determines that such action may not lawfully be taken by the Issuer or if the
Trustee in good faith by its board of directors or board of trustees, executive
committee or a trust committee of directors or trustees shall determine that
such action would expose the Trustee to personal liability to existing Holders
or would affect the Trustee's own rights, duties or immunities under the
Securities, this Indenture or otherwise.

         If the Issuer shall establish pursuant to Section 2.3 that the
Securities of a series are to be issued in the form of one or more Registered
Global Securities, then the Issuer shall execute and the Trustee shall, in
accordance with this Section and the Issuer Order with respect to such series,
authenticate and deliver one or more Registered Global Securities that (i) shall
represent and shall be denominated in an amount equal to the aggregate principal
amount


                                       7



of all of the Securities of such series issued and not yet canceled, (ii) shall
be registered in the name of the Depository for such Registered Global Security
or Securities or the nominee of such Depository, (iii) shall be delivered by the
Trustee to such Depository or delivered or held pursuant to such Depository's
instructions and (iv) shall bear a legend substantially to the following effect:
"Unless and until it is exchanged in whole or in part for Securities in
definitive registered form, this Security may not be transferred except as a
whole by the Depository to the nominee of the Depository or by a nominee of the
Depository to the Depository or another nominee of the Depository or by the
Depository or any such nominee to a successor Depository or a nominee of such
successor Depository."

         Each Depository designated pursuant to Section 2.3 must, at the time of
its designation and at all times while it serves as Depository, be a clearing
agency registered under the Exchange Act and any other applicable statute or
regulation.

          SECTION 2.5. Execution Of Securities. The Securities shall be signed
on behalf of the Issuer by the chairman or vice chairman of its Board of
Directors or its president, or any executive (senior or other), a vice president
or its treasurer, under its corporate seal which may, but need not, be attested.
Such signatures may be the manual or facsimile signatures of the present or any
future such officers. The seal of the Issuer may be in the form of a facsimile
thereof and may be impressed, affixed, imprinted or otherwise reproduced on the
Securities. Typographical and other minor errors or defects in any such
reproduction of the seal or any such signature shall not affect the validity or
enforceability of any Security that has been duly authenticated and delivered by
the Trustee.

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

          SECTION 2.6. Certificate Of Authentication. Only such Securities as
shall bear thereon a certificate of authentication substantially in the form
hereinbefore recited, executed by the Trustee by the manual signature of one of
its authorized officers, shall be entitled to the benefits of this Indenture or
be valid or obligatory for any purpose. The execution of such certificate by the
Trustee upon any Security executed by the Issuer shall be conclusive evidence
that the Security so authenticated has been duly authenticated and delivered
hereunder and that the Holder is entitled to the benefits of this Indenture.

          SECTION 2.7. Denomination And Date Of Securities; Payment Of Interest.
Unless otherwise provided in Section 2.3, the Securities of each series shall be
issuable as Registered Securities in denominations of $1,000 and any integral
multiple thereof. The Securities of each series shall be numbered, lettered or
otherwise distinguished in such manner or in accordance with such plan as the
officers of the Issuer executing the same may determine with the approval of the
Trustee, as evidenced by the execution and authentication thereof.

          Each Registered Security shall be dated the date of its
authentication. The Securities of each series shall bear interest, if any, from
the date, and such interest shall be payable on the dates, established as
contemplated by Section 2.3.

          The person in whose name any Registered Security of any series is
registered at the close of business on any record date applicable to a
particular series with respect to any interest payment date for such series
shall be entitled to receive the interest, if any, payable on such interest
payment date notwithstanding any transfer or exchange of such Registered
Security subsequent to the record date and prior to such interest payment date,
except if and to the extent the Issuer shall default in the payment of the
interest due on such interest payment date for such series, in which case such
defaulted interest shall be paid to the persons in whose names Outstanding
Registered Securities for such series are registered at the close of business on
a subsequent record date (which shall be not less than five Business Days prior
to the date of payment of such defaulted interest) established by notice given
by mail by or on behalf of the Issuer to the Holders of Registered Securities
not less than 15 days preceding such subsequent record date. The term "record
date" as used with respect to any interest payment date (except a date for
payment of defaulted interest) for the Securities of any series shall mean the
date specified as such in the terms of the Registered


                                       8



Securities of such series established as contemplated by Section 2.3, or, if no
such date is so established, if such interest payment date is the first day of a
calendar month, the fifteenth day of the preceding calendar month or, if such
interest payment date is the fifteenth day of a calendar month, the first day of
such calendar month, whether or not such record date is a Business Day.

          SECTION 2.8. Registration, Transfer And Exchange. The Issuer will keep
at each office or agency to be maintained for the purpose as provided in Section
3.2 for each series of Securities a register or registers in which, subject to
such reasonable regulations as the Issuer may prescribe, it will provide for the
registration of Registered Securities of such series and the registration of
transfer of Registered Securities of such series. Such register shall be in
written form in the English language or in any other form capable of being
converted into such form within a reasonable time. At all reasonable times such
register or registers shall be open for inspection by the Trustee.

         Upon due presentation for registration of transfer of any Registered
Security of any series at any such office or agency to be maintained for the
purpose as provided in Section 3.2, the Issuer shall execute and the Trustee
shall authenticate and deliver in the name of the transferee or transferees a
new Registered Security or Registered Securities of the same series, maturity
date, interest rate and original issue date in authorized denominations for a
like aggregate principal amount.

         At the option of the Holder thereof, Registered Securities of any
series (other than a Registered Global Security, except as set forth below) may
be exchanged for a Registered Security or Registered Securities of such series
having authorized denominations and an equal aggregate principal amount, upon
surrender of such Registered Securities to be exchanged at the agency of the
Issuer that shall be maintained for such purpose in accordance with Section 3.2
and upon payment, if the Issuer shall so require, of the charges hereinafter
provided. Whenever any Securities are so surrendered for exchange, the Issuer
shall execute, and the Trustee shall authenticate and deliver, the Securities
which the Holder making the exchange is entitled to receive. All Securities
surrendered upon any exchange or transfer provided for in this Indenture shall
be promptly cancelled and disposed of by the Trustee, and the Trustee shall
deliver a certificate of disposition thereof to the Issuer.

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

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

         The Issuer shall not be required to exchange or register a transfer of
(a) any Securities of any series for a period of 15 days preceding the first
mailing of notice of redemption of Securities of such series to be redeemed or
(b) any Securities selected, called or being called for redemption, in whole or
in part, except, in the case of any Security to be redeemed in part, the portion
thereof not so to be redeemed.

         Notwithstanding any other provision of this Section 2.8, unless and
until it is exchanged in whole or in part for Securities in definitive
registered form, a Registered Global Security representing all or a portion of
the Securities of a series may not be transferred except as a whole by the
Depositary for such series to a nominee of such Depositary or by a nominee of
such Depositary to such Depositary or another nominee of such Depositary or by
such Depositary or any such nominee to a successor Depositary for such series or
a nominee of such successor Depositary.

         If at any time the Depositary for any Registered Securities of a series
represented by one or more Registered Global Securities notifies the Issuer that
it is unwilling or unable to continue as Depositary for such Registered
Securities or if at any time the Depositary for such Registered Securities shall
no longer be eligible under Section 2.4, the Issuer shall appoint a successor
Depositary eligible under Section 2.4 with respect to such Registered
Securities. If a successor Depositary eligible under Section 2.4 for such
Registered Securities is not appointed by the Issuer within 90 days after the
Issuer receives such notice or becomes aware of such ineligibility,


                                       9



the Issuer's election pursuant to Section 2.3 that such Registered Securities be
represented by one or more Registered Global Securities shall no longer be
effective and the Issuer will execute, and the Trustee, upon receipt of an
Officer's Certificate for the authentication and delivery of definitive
Securities of such series, will authenticate and deliver, Securities of such
series in definitive registered form in any authorized denominations, in an
aggregate principal amount equal to the principal amount of the Registered
Global Security or Securities representing such Registered Securities in
exchange for such Registered Global Security or Securities.

         The Issuer may at any time and in its sole discretion determine that
the Registered Securities of any series issued in the form of one or more
Registered Global Securities shall no longer be represented by a Registered
Global Security or Securities. In such event the Issuer, will execute, and the
Trustee, upon receipt of any Officer's Certificate for the authentication and
delivery of definitive Securities of such series, will authenticate and deliver,
Securities of such series in definitive registered form in any authorized
denominations, in an aggregate principal amount equal to the principal amount of
the Registered Global Security or Securities representing such Registered
Securities, in exchange for such Registered Global Security or Securities.

         If specified by the Issuer pursuant to Section 2.3 with respect to
Securities represented by a Registered Global Security, the Depositary for such
Registered Global Security may surrender such Registered Global Security in
exchange in whole or in part for Securities of the same series in definitive
registered form on such terms as are acceptable to the Issuer and such
Depositary. Thereupon, the Issuer shall execute, and the Trustee shall
authenticate and deliver, without service charge:

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

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

         Upon the exchange of a Registered Global Security for Securities in
definitive registered form in authorized denominations, such Registered Global
Security shall be cancelled by the Trustee or an agent of the Issuer or the
Trustee. Securities in definitive registered form issued in exchange for a
Registered Global Security pursuant to this Section 2.8 shall be registered in
such names and in such authorized denominations as the Depositary for such
Registered Global Security, pursuant to instructions from its direct or indirect
participants or otherwise, shall instruct the Trustee or an agent of the Issuer
or the Trustee. The Trustee or such agent shall deliver such Securities to or as
directed by the Persons in whose names such Securities are so registered.

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

          SECTION 2.9. Mutilated, Defaced, Destroyed, Lost And Stolen
Securities. In case any temporary or definitive Security shall be mutilated,
defaced, destroyed, lost or stolen, the Issuer in its discretion may execute
and, upon the written request of any officer of the Issuer, the Trustee shall
authenticate and deliver, a new Security of the same series, maturity date,
interest rate and original issue date, bearing a number or other distinguishing
symbol not contemporaneously outstanding, in exchange and substitution for the
mutilated or defaced Security, or in lieu of and in substitution for the
Security so destroyed, lost or stolen. In every case, the applicant for a
substitute Security shall furnish to the Issuer and to the Trustee and any agent
of the Issuer or the Trustee such security or indemnity as may be required by
them to indemnify and defend and to save each of them harmless and, in every
case of destruction, loss or theft, evidence to their satisfaction of the
destruction, loss or theft of such Security and of the ownership thereof, and in
the case of mutilation or defacement shall surrender the Security to the Trustee
or such agent.


                                       10



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

         Every substitute Security of any series issued pursuant to the
provisions of this Section by virtue of the fact that any such Security is
destroyed, lost or stolen shall constitute an additional contractual obligation
of the Issuer, whether or not the destroyed, lost or stolen Security shall be at
any time enforceable by anyone and shall be entitled to all the benefits of (but
shall be subject to all the limitations of rights set forth in) this Indenture
equally and proportionately with any and all other Securities of such series
duly authenticated and delivered hereunder. All Securities shall be held and
owned upon the express condition that, to the extent permitted by law, the
foregoing provisions are exclusive with respect to the replacement or payment of
mutilated, defaced or destroyed, lost or stolen Securities and shall preclude
any and all other rights or remedies notwithstanding any law or statute existing
or hereafter enacted to the contrary with respect to the replacement or payment
of negotiable instruments or other securities without their surrender.

          SECTION 2.10. Cancellation Of Securities; Destruction Thereof. All
Securities surrendered for payment, redemption, registration of transfer or
exchange, or for credit against any payment in respect of a sinking or analogous
fund, if any, if surrendered to the Issuer or any agent of the Issuer or the
Trustee or any agent of the Trustee, shall be delivered to the Trustee or its
agent for cancellation or, if surrendered to the Trustee, shall be canceled by
it; and no Securities shall be issued in lieu thereof except as expressly
permitted by any of the provisions of this Indenture. The Trustee or its agent
shall dispose of canceled Securities held by it and, upon written request
therefore, shall deliver a certificate of disposition to the Issuer. If the
Issuer or its agent shall acquire any of the Securities, such acquisition shall
not operate as a redemption or satisfaction of the indebtedness represented by
such Securities unless and until the same are delivered to the Trustee or its
agent for cancellation.

          SECTION 2.11. Temporary Securities. Pending the preparation of
definitive Securities for any series, the Issuer may execute and the Trustee
shall authenticate and deliver temporary Securities for such series (printed,
lithographed, typewritten or otherwise reproduced, in each case in form
satisfactory to the Trustee). Temporary Securities of any series shall be
issuable as Registered Securities without coupons of any authorized
denomination, and substantially in the form of the definitive Securities of such
series but with such omissions, insertions and variations as may be appropriate
for temporary Securities, all as may be determined by the Issuer with the
concurrence of the Trustee as evidenced by the execution and authentication
thereof. Temporary Securities may contain such references to any provisions of
this Indenture as may be appropriate. Every temporary Security shall be executed
by the Issuer and be authenticated by the Trustee upon the same conditions and
in substantially the same manner, and with like effect, as the definitive
Securities. Without unreasonable delay, the Issuer shall execute and shall
furnish definitive Securities of such series and thereupon temporary Registered
Securities of such series may be surrendered in exchange therefor without charge
at each office or agency to be maintained by the Issuer for that purpose
pursuant to Section 3.2 and the Trustee shall authenticate and deliver in
exchange for such temporary Securities of such series an equal aggregate
principal amount of definitive Securities of the same series having authorized
denominations. Until so exchanged, the temporary Securities of any series shall
be entitled to the same benefits under this Indenture as definitive Securities
of such series, unless otherwise established pursuant to Section 2.3.

                                  ARTICLE III

                             COVENANTS OF THE ISSUER

          SECTION 3.1. Payment Of Principal And Interest. The Issuer covenants
and agrees for the benefit of each series of Securities that it will duly and
punctually pay or cause to be paid the principal of (and premium, if any), and
interest on, each of the Securities of such series (together with any additional
amounts payable pursuant to the terms of such Securities) at the place or
places, at the respective time or times and in the manner provided in such
Securities in this Indenture. The interest, if any, on Registered Securities
(together with any additional amounts payable pursuant to the terms of such
Securities) shall be payable only to or upon the written order of the Holders
thereof and, at the option of the Issuer, may be paid by wire transfer or by
mailing checks for such interest payable to or upon the written order of such
Holders at their last addresses as they appear on the Securities register of the
Issuer.

          SECTION 3.2. Offices For Payments, Etc. So long as any Registered
Securities (other than Global Registered Securities) are authorized for issuance
pursuant to this Indenture or are outstanding hereunder, the Issuer will
maintain in New York, an office or agency where the Registered Securities of
each series may be presented for payment, where the Securities of each series
may be presented for exchange as is provided in this Indenture and, if
applicable, pursuant to Section 2.3 and where the Registered Securities of each
series may be presented for registration of transfer as in this Indenture
provided.

         Notices and demands to or upon the Issuer in respect of the Securities
of any series or this Indenture may be served on the Issuer at the corporate
trust office of the Trustee.

         The Issuer will give to the Trustee written notice of the location of
each such office or agency and of any change of location thereof. In case the
Issuer shall fail to maintain any agency required by this Section to be located
in New York, or shall fail to give such notice of the location or for any change
in the location of any of the above agencies, presentations and demands may be
made and notices may be served at the Corporate Trust Office of the Trustee.

         The Issuer may from time to time designate one or more additional
offices or agencies where the Securities of a series may be presented for
payment, where the Securities of that series may be presented for exchange as
provided in this Indenture and pursuant to Section 2.3 and where the Registered
Securities of that series may be presented for registration of transfer as in
this Indenture provided, and the Issuer may from time to time rescind any such
designation, as the Issuer may deem desirable or expedient; PROVIDED, that no
such designation or rescission shall in any manner relieve the Issuer of its
obligations to maintain the agencies provided for in this Section. The Issuer
shall give to the Trustee prompt written notice of any such designation or
rescission thereof.

          SECTION 3.3. Appointment To Fill A Vacancy In Office Of Trustee. The
Issuer, whenever necessary to avoid or fill a vacancy in the office of Trustee,
will appoint, in the manner provided in Section 6.10, a Trustee, so that there
shall at all times be a Trustee with respect to each series of Securities
hereunder.

          SECTION 3.4. Paying Agents. Whenever the Issuer shall appoint a paying
agent other than the Trustee with respect to the Securities of any series, it
will cause such paying agent to execute and deliver to the Trustee an instrument
in which such agent shall agree with the Trustee, subject to the provisions of
this Section:

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

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



                                       12



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

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

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

         Anything in this Section to the contrary notwithstanding, but subject
to Section 9.1, the Issuer may at any time, for the purpose of obtaining a
satisfaction and discharge with respect to one or more or all series of
Securities hereunder, or for any other reason, pay or cause to be paid to the
Trustee all sums held in trust for any such series by the Issuer or any paying
agent hereunder, as required by this Section, such sums to be held by the
Trustee upon the trusts herein contained.

         Anything in this Section to the contrary notwithstanding, the agreement
to hold sums in trust as provided in this Section is subject to the provisions
of Sections 9.3 and 9.4.

          SECTION 3.5. Compliance Certificates. The Issuer will furnish to the
Trustee on or before January 31 in each year (beginning with January 31, 2002) a
brief certificate (which need not comply with Section 10.5) from the principal
executive, financial or accounting officer of the Issuer stating that in the
course of the performance by the signer of his or her duties as an officer of
the Issuer he or she would normally have knowledge of any default or
non-compliance by the Issuer in the performance of any covenants or conditions
contained in this Indenture, stating whether or not he or she has knowledge of
any such default or non-compliance and, if so, describing each such default or
non-compliance of which the signer has knowledge and the nature of such default
or non-compliance.

          SECTION 3.6. Corporate Existence. Except as provided in Section 3.8,
the Issuer will do or cause to be done all things necessary to preserve and keep
in full force and effect its corporate existence.

          SECTION 3.7. Payment Of Taxes And Other Claims. The Issuer will pay or
discharge or cause to be paid or discharged, before the same shall become
delinquent: (a) all taxes, assessments and governmental charges levied or
imposed upon the Issuer or any Subsidiary or upon the income, profits or
property of the Issuer or any Subsidiary; and (b) all lawful claims for labor,
materials and supplies, which, if unpaid, might by law become a lien upon the
property of the Issuer or any Subsidiary; PROVIDED, that the Issuer shall not be
required to pay or discharge or cause to be paid or discharged any such tax,
assessment, charge or claim whose amount, applicability or validity is being
contested in good faith by appropriate proceedings.

          SECTION 3.8. The Issuer May Not Merge. The Issuer may not consolidate
with or merge with or into, or sell, convey, transfer or lease all or
substantially all of its assets (either in one transaction or a series of
transactions) to any Person unless:

(a)      the Person formed by or surviving such consolidation or merger or to
         which such sale, conveyance, transfer or lease shall have been made
         (the "Successor") if other than the Issuer, (a) is organized and
         existing under the laws of the United States of America or any State
         thereof or the District of Columbia, and (b) shall expressly assume by
         a supplemental indenture, executed and delivered to the Trustee, in
         form satisfactory to the Trustee, all the obligations of the Issuer
         under the Securities and this Indenture;


                                       13



(b)      immediately prior to and after giving effect to such transaction (and
         treating any indebtedness which becomes an obligation of the Successor
         or any Subsidiary as a result of such transaction as having been
         incurred by such Successor or such Subsidiary at the time of such
         transaction), no Event of Default shall have occurred and be
         continuing; and

(c)      the Issuer, delivers to the Trustee an Officer's Certificate and an
         Opinion of Counsel, each stating that such consolidation, merger, sale,
         conveyance, transfer or lease and such supplemental indenture comply
         with this Indenture.

                  The Successor will be the successor to the Issuer, and will be
substituted for, and may exercise every right and power and become the obligor
on the Securities with the same effect as if the Successor had been named, as
the Issuer herein but, in the case of a sale, conveyance, transfer or lease of
all or substantially all of the assets of the Issuer, the predecessor Issuer
will not be released from its obligation to pay the principal of, premium, if
any, and interest on the Securities.

                             ISSUER AND THE TRUSTEE

          SECTION 4.1. Issuer To Furnish Trustee Information As To Names And
Addresses Of Securityholders. If and so long as the Trustee shall not be the
Security registrar for the Securities of any series, the Issuer and any other
obligor on the Securities will furnish or cause to be furnished to the Trustee a
list in such form as the Trustee may reasonably require of the names and
addresses of the Holders of the Registered Securities of such series pursuant to
Section 312 of the Trust Indenture Act:

(a)      semi-annually not more than 5 days after each record date for the
         payment of interest on such Registered Securities, as hereinabove
         specified, as of such record date and on dates to be determined
         pursuant to Section 2.3 for non-interest bearing Registered Securities
         in each year; and

(b)      at such other times as the Trustee may reasonably request in writing,
         within thirty days after receipt by the Issuer of any such request as

         furnished.

          SECTION 4.2. Reports By The Issuer. The Issuer covenants to file with
the Trustee, within 15 days after the Issuer is required to file the same with
the Commission, copies of the annual reports and of the information, documents,
and other reports that the Issuer may be required to file with the Commission
pursuant to Section 13 or Section 15(d) of the Exchange Act or pursuant to
Section 314 of the Trust Indenture Act.

         Upon the written request and at the expense of and payable in advance
by any Securityholder, the Trustee shall provide such reports, information or
documents as have been provided to it under this Section 4.2. The Trustee shall
not have any obligation to review any report, information or documents provided
to the Trustee by the Issuer pursuant to this Section 4.2, nor shall the Trustee
be deemed to have notice of any item contained therein or Event of Default which
may be disclosed therein in any manner. The Trustee's sole responsibility with
respect to such reports shall be to act as the depository for such report for
the Securityholders and to make such reports available to the Securityholders in
accordance with this Section 4.2. The Trustee shall have no duty to request
copies of any such reports, information or documents which are required to be
furnished to it hereunder.

          SECTION 4.3. Reports By The Trustee.

(a)      On or before the first July 15 which occurs not less than 60 days after
         the earliest date of issuance of any Securities and on or before July
         15 in each year thereafter, so long as any Securities are Outstanding
         hereunder, the Trustee shall transmit by mail as provided below to the
         Securityholders of each series of outstanding Securities, as
         hereinafter in this Section provided, a brief report dated as of the
         preceding May 15 with respect to:


                                       14



(i)      its eligibility under Section 6.10 and its qualification under Section
         6.9, or in lieu thereof, if to the best of its knowledge it has
         continued to be eligible and qualified under such Sections, a written
         statement to such effect;

(ii)     the character and amount of any advances (and if the Trustee elects to
         so state, the circumstances surrounding the making thereof) made by the
         Trustee (as such) which remain unpaid on the date of such report and
         for the reimbursement of which it claims or may claim a lien or charge,
         prior to that of the Securities of such series, on any property or
         funds held or collected by it as Trustee, except that the Trustee shall
         not be required (but may elect) to report such advances if such
         advances so remaining unpaid aggregate not more than 0.5% of the
         principal of the Securities of such series outstanding on the date of
         such report;

(iii)    the amount, interest rate and maturity date of all other indebtedness
         owing by the Issuer (or any other obligor on the Securities of such
         series) to the Trustee in its individual capacity on the date of such
         report, with a brief description of any property held as collateral
         security therefor, except any indebtedness based upon a creditor
         relationship;

(iv)     the property and funds, if any, physically in the possession of the
         Trustee (as such) in respect of the Securities of such series on the
         date of such report;

(v)      any additional issue of Securities of such series which the Trustee has
         not previously reported; and

(vi)     any action taken by the Trustee in the performance of its duties under
         this Indenture which the Trustee has not previously reported and which
         in the Trustee's opinion materially affects the Securities of such
         series, except action in respect of a default, notice of which has been
         or is to be withheld by it in accordance with the provisions of Section
         5.11.

            (b)   The Trustee shall transmit to the Securityholders of each
                  series, as provided in subsection (c) of this Section, a brief
                  report with respect to the character and amount of any
                  advances (and if the Trustee elects so to state, the
                  circumstances surrounding the making thereof) made by the
                  Trustee (as such) in respect of the Securities of such series
                  since the date of the last report transmitted pursuant to the
                  provisions of subsection (a) of this Section (or if no such
                  report has yet been so transmitted, since the date of this
                  Indenture) for the reimbursement of which it claims or may
                  claim a lien or charge prior to that of the Securities of such
                  series on property or funds held or collected by it as Trustee
                  and which it has not previously reported pursuant to this
                  subsection (b), except that the Trustee shall not be required
                  (but may elect) to report such advances if such advances
                  remaining unpaid at any time aggregate 10% or less of the
                  principal amount of Securities of such series outstanding at
                  such time, such report to be transmitted within 90 days after
                  such time.

            (c)   Reports pursuant to this Section shall be transmitted by mail
                  to all Holders of Securities of such series, as the names and
                  addresses of such Holders appear upon the Securities register
                  as of a date not more than 15 days prior to the mailing
                  thereof.

            (d)   A copy of each such report shall, at the time of such
                  transmission to Securityholders, be furnished to the Issuer
                  and be filed by the Trustee with each stock exchange upon
                  which the Securities of such series are listed and also with
                  the Commission. The Issuer agrees to notify the Trustee when
                  and as Securities of any series become listed on any national
                  securities exchange.

                                   ARTICLE V

                   REMEDIES OF THE TRUSTEE AND SECURITYHOLDERS
                               ON EVENT OF DEFAULT



                                       15



          SECTION 5.1. Event Of Default Defined, Acceleration Of Maturity;
Waiver Of Default. "Event of Default" with respect to Securities of any series,
wherever used herein, means any one of the following events which shall have
occurred and be continuing (whatever the reason for such Event of Default and
whether it shall be voluntary or involuntary or be effected by operation of law
or pursuant to any judgment, decree or order of any court or any order, rule or
regulation of any administrative or governmental body):

            (a)   default in the payment of any installment of interest upon any
                  of the Securities of such series as and when the same shall
                  become due and payable, and continuance of such default for a
                  period of 30 days; provided that, a valid extension of an
                  interest payment period by the Issuer in accordance with the
                  terms of such Securities shall not constitute a failure to pay
                  interest; or

            (b)   default in the payment of all or any part of the principal or
                  premium (if any) on any of the Securities of such series as

                  maturity, upon any redemption, by declaration or otherwise; or

            (c)   default in the payment of any sinking fund installment as and
                  when the same shall become due and payable by the terms of the
                  Securities of such series; or

            (d)   failure on the part of the Issuer duly to observe or perform
                  any other of the covenants or agreements on the part of the
                  Issuer in the Securities of such series or contained in this
                  Indenture (other than a covenant or agreement included in this
                  Indenture solely for the benefit of a series of Securities
                  other than such series) for a period of 60 days after the date
                  on which written notice specifying such failure, stating that
                  such notice is a "Notice of Default" hereunder and demanding
                  that the Issuer remedy the same, shall have been given by
                  registered or certified mail, return receipt requested, to the
                  Issuer by the Trustee, or to the Issuer and the Trustee by the
                  holders of at least 25% in aggregate principal amount of the
                  Outstanding Securities of the series to which such covenant or
                  agreement relates; or

            (e)   a court having jurisdiction in the premises shall enter a
                  decree or order for relief in respect of the Issuer in an
                  involuntary case under any applicable bankruptcy, insolvency
                  or other similar law now or hereafter in effect, or appointing
                  a receiver, liquidator, assignee, custodian, trustee,
                  sequestrator (or similar official) of the Issuer for any
                  substantial part of its or their property or ordering the
                  winding up or liquidation of its or their affairs, and such
                  decree or order shall remain unstayed and in effect for a
                  period of 60 consecutive days; or

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

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

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

         Except as otherwise provided in the terms of any series of Securities
pursuant to Section 2.3, if an Event of Default described in clause (d) or (g)
above with respect to all series of the Securities then Outstanding, occurs and
is continuing, then, and in each and every such case, unless the Principal of
all of the Securities shall have already


                                       16



become due and payable, either the Trustee or the Holders of not less than 25%
in aggregate principal amount of all of the Securities then Outstanding
hereunder (treated as one class) by notice in writing to the Issuer (and to the
Trustee if given by Securityholders), may declare the entire principal (or, if
the Securities of any series are Original Issue Discount Securities, such
portion of the principal amount as may be specified in the terms of such series)
of all of the Securities then Outstanding, and the interest accrued thereon, if
any, to be due and payable immediately, and upon such declaration, the same
shall become immediately due and payable.

         If an Event of Default described in clause (e) or (f) above occurs and
is continuing, then the principal amount of all the Securities then Outstanding,
and the interest accrued thereon, if any, shall become and be immediately due
and payable without any declaration or other act on the part of the Trustee or
any Holder.

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

         The foregoing provisions are subject to the condition that if, at any
time after the principal (or, if the Securities are Original Issue Discount
Securities, such portion of the principal as may be specified in the terms
thereof) of the Securities of any series (or of all the Securities, as the case
may be) shall have been so declared due and payable, and before any judgment or
decree for the payment of the moneys due shall have been obtained or entered as
hereinafter provided, the Issuer shall pay or shall deposit with the Trustee a
sum sufficient to pay

(a)      all matured installments of interest upon all the Securities of such
         series (or all the Securities, as the case may be); and

            (i)   the principal of any and all Securities of such series (or of
                  all the Securities, as the case may be) which shall have
                  become due otherwise than by acceleration; and

            (ii)  interest upon such principal and, to the extent that payment
                  of such interest is enforceable under applicable law, on
                  overdue installments of interest, at the same rate as the rate
                  of interest or Yield to Maturity (in the case of Original
                  Issue Discount Securities) specified in the Securities of such
                  series (or at the respective rates of interest or Yields to
                  Maturity of all the Securities, as the case may be) to the
                  date of such payment or deposit; and

            (iii) all amounts payable to the Trustee pursuant to Section 6.6;
                  and

(b)      all Events of Default under the Indenture, other than the non-payment
         of the principal of Securities which shall have become due by
         acceleration, shall have been cured, waived or otherwise remedied as
         provided herein,

then and in every such case the Holders of a majority, or any applicable
supermajority, in aggregate principal amount of all the Securities of such
series voting as a separate class (or all the Securities, as the case may be,
voting as a single class), then Outstanding, by written notice to the Issuer and
to the Trustee, may waive all defaults with respect to such series (or with
respect to all the Securities, as the case may be) and rescind and annul such
declaration and its consequences, but no such waiver or rescission and annulment
shall extend to or shall affect any subsequent default or shall impair any right
consequent thereon.

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


                                       17




Issue Discount Securities shall be deemed, for all purposes hereunder, to be
such portion of the principal thereof as shall be due and payable as a result of
such acceleration, and payment of such portion of the principal thereof as shall
be due and payable as a result of such acceleration, together with interest, if
any, thereon and all other amounts owing thereunder, shall constitute payment in
full of such Original Issue Discount Securities.

          SECTION 5.2. Collection Of Indebtedness By Trustee; Trustee May Prove
Debt. The Issuer covenants that (a) in case default shall be made in the payment
of any installment of interest on any of the Securities of any series when such
interest shall have become due and payable, and such default shall have
continued for a period of 30 days, or (b) in case default shall be made in the
payment of all or any part of the principal of any of the Securities of any
series when the same shall have become due and payable, whether upon maturity of
the Securities of such series or upon any redemption or by declaration or
otherwise, then upon demand of the Trustee, the Issuer will pay to the Trustee
for the benefit of the Holders of the Securities of such series the whole amount
that then shall have become due and payable on all Securities of such series,
for principal and interest, as the case may be (with interest to the date of
such payment upon the overdue principal and, to the extent that payment of such
interest is enforceable under applicable law, on overdue installments of
interest at the same rate as the rate of interest or Yield to Maturity (in the
case of Original Issue Discount Securities) specified in the Securities of such
series); and in addition thereto, such further amount as shall be sufficient to
cover the costs and expenses of collection, and such other amount due the
Trustee under Section 6.6 in respect of Securities of such series.

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

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

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

            (a)   to file and prove a claim or claims for the whole amount of
                  principal and interest (or, if the Securities of any series
                  are Original Issue Discount Securities, such portion of the
                  principal amount as may be specified in the terms of such
                  series) owing and unpaid in respect of the Securities of any
                  series, and to file such other papers or documents as may be
                  necessary or advisable in order to have the claims of the
                  Trustee (including any claim for amounts payable to the
                  Trustee under Section 6.6) and of the Securityholders allowed
                  in any judicial proceedings relative to the Issuer or other
                  obligor upon the Securities, or to the creditors or property
                  of the Issuer or such other obligor; and

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

            (c)   to collect and receive any moneys or other property payable or
                  deliverable on any such claims, and to distribute all amounts
                  received with respect to the claims of the Securityholders and
                  of the Trustee on their behalf; and any trustee, receiver, or
                  liquidator, custodian or other similar official performing



                                       18



                  similar functions in respect of any such proceedings is hereby
                  authorized by each of the Securityholders to make payments to
                  the Trustee, and, in the event that the Trustee shall consent
                  to the making of payments directly to the Securityholders, to
                  pay to the Trustee its costs and expenses of collection and
                  all other amounts due to it pursuant to Section 6.6.

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

         All rights of action and of asserting claims under this Indenture, or
under any of the Securities of any series may be enforced by the Trustee without
the possession of any of the Securities of such series or the production thereof
in any trial or other proceedings relative thereto, and any such action or
proceedings instituted by the Trustee shall be brought in its own name as
trustee of an express trust, and any recovery of judgment shall be awarded to
the Trustee for ratable distribution to the Holders of the Securities in respect
of which such action was taken, after payment of all sums due to the Trustee
under Section 6.6 in respect of such Securities.

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

          SECTION 5.3. Application Of Proceeds. Any moneys collected by the
Trustee pursuant to this Article in respect of any series shall be applied in
the following order at the date or dates fixed by the Trustee and, in case of
the distribution of such moneys on account of principal or interest, upon
presentation of the several Securities in respect of which monies have been
collected and stamping (or otherwise noting) thereon the payment, or issuing
Securities of such series in reduced principal amounts in exchange for the
presented Securities of like series if only partially paid, or upon surrender
thereof if fully paid:

         FIRST: To the payment of costs and expenses applicable to such series
of Securities in respect of which monies have been collected, including all
amounts due to the Trustee and each predecessor Trustee pursuant to Section 6.6
in respect to such series of Securities;

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

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

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



                                       19



          SECTION 5.4. Suits For Enforcement. In case an Event of Default has
occurred, has not been waived and is continuing, the Trustee may in its
discretion proceed to protect and enforce the rights vested in it by this
Indenture by such appropriate judicial proceedings as the Trustee shall deem
most effectual to protect and enforce any of such rights, either at law or in
equity or in bankruptcy or otherwise, whether for the specific enforcement of
any covenant or agreement contained in this Indenture or in aid of the exercise
of any power granted in this Indenture or to enforce any other legal or
equitable right vested in the Trustee by this Indenture or by law.

          SECTION 5.5. Restoration Of Rights On Abandonment Of Proceedings. In
case the Trustee or any Holder of any Security shall have proceeded to enforce
any right under this Indenture and such proceedings shall have been discontinued
or abandoned for any reason, or shall have been determined adversely to the
Trustee or to such Holder, then and in every such case the Issuer, the Trustee
and the Holders of Securities shall be restored severally and respectively to
their former positions and rights hereunder, and all rights, remedies and powers
of the Issuer, the Trustee and the Securityholders shall continue as though no
such proceedings had been taken.

          SECTION 5.6. Limitations On Suits By Securityholders. No Holder of any
Security of any series shall have any right by virtue or by availing of any
provision of this Indenture to institute any action or proceeding at law or in
equity or in bankruptcy or otherwise upon or under or with respect to this
Indenture or such Security, or for the appointment of a trustee, receiver,
liquidator, custodian or other similar official or for any other remedy
hereunder or thereunder, unless (a) such Holder previously shall have given to
the Trustee written notice of an Event of Default with respect to Securities of
such series and of the continuance thereof, as hereinbefore provided, and (b)
the Holders of not less than 25% in aggregate principal amount of the Securities
of such series then Outstanding (treated as a single class) shall have made
written request upon the Trustee to institute such action or proceedings in its
own name as Trustee hereunder and shall have offered to the Trustee such
reasonable indemnity as it may require against the costs, expenses and
liabilities to be incurred therein or thereby, and (c) the Trustee for 60 days
after its receipt of such notice, request and offer of indemnity shall have
failed to institute any such action or proceeding, and (d) no direction
inconsistent with such written request shall have been given to the Trustee
pursuant to Section 5.9; it being understood and intended, and being expressly
covenanted by the taker and Holder of every Security with every other taker and
Holder and the Trustee, that no one or more Holders of Securities of any series
shall have any right in any manner whatever by virtue or by availing of any
provision of this Indenture or any Security to affect, disturb or prejudice the
rights of any other such taker or Holder of Securities or to obtain or seek to
obtain priority over or preference to any other such taker or Holder or to
enforce any right under this Indenture or any Security, except in the manner
herein provided and for the equal, ratable and common benefit of all Holders of
Securities of the applicable series. For the protection and enforcement of the
provisions of this Section, each and every Securityholder and the Trustee shall
be entitled to such relief as can be given either at law or in equity.

          SECTION 5.7. Unconditional Right Of Securityholders To Institute
Certain Suits. Notwithstanding any other provision in this Indenture and any
provision of any Security, the right of any Holder of any Security to receive
payment of the principal of and interest on such Security on or after the
respective due dates expressed in such Security or the applicable redemption
dates provided for in such Security, or to institute suit for the enforcement of
any such payment on or after such respective dates, shall not be impaired or
affected without the consent of such Holder.

          SECTION 5.8. Powers And Remedies Cumulative; Delay Or Omission Not
Waiver Of Default. Except as provided in Section 5.6, no right or remedy herein
conferred upon or reserved to the Trustee or to the Holders of Securities is
intended to be exclusive of any other right or remedy and every right and remedy
shall, to the extent permitted by law, be cumulative and in addition to every
other right and remedy given hereunder or now or hereafter existing at law or in
equity or otherwise. The assertion or employment of any right or remedy
hereunder, or otherwise, shall not prevent the concurrent assertion or
employment of any other appropriate right or remedy.

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



                                       20



          SECTION 5.9. Control By Holders Of Securities. The Holders of a
majority in aggregate principal amount of the Securities of each series affected
(with each such series voting as a separate class) at the time Outstanding shall
have the right to direct the time, method and place of conducting any proceeding
for any remedy available to the Trustee, or exercising any trust or power
conferred on the Trustee with respect to the Securities of such series by this
Indenture; PROVIDED, that such Holders shall have offered to the Trustee such
reasonable indemnity as it may require against costs, expenses and liabilities
to be incurred therein or thereby, and PROVIDED FURTHER, that such direction
shall not be otherwise than in accordance with law and the provisions of this
Indenture; and PROVIDED, FURTHER, that (subject to the provisions of Section
6.1) the Trustee shall have the right to decline to follow any such direction if
(a) the Trustee, being advised by counsel, shall determine that the action or
proceeding so directed may not lawfully be taken; or (b) if the Trustee by its
board of directors, the executive committee or a trust committee of directors or
Responsible Officers of the Trustee shall determine in good faith that the
action or proceedings so directed would involve the Trustee in personal
liability; or (c) if the Trustee in good faith shall so determine that the
actions or forbearances specified in or pursuant to such direction would be
unduly prejudicial to the interests of Holders of the Securities of all affected
series not joining in the giving of said direction, it being understood that
(subject to Section 6.1) the Trustee shall have no duty to ascertain whether or
not such actions or forbearances are unduly prejudicial to such Holders.

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

          SECTION 5.10. Waiver Of Past Defaults. Prior to the declaration of
acceleration of the maturity of the Securities of any series as provided in
Section 5.1, the Holders of a majority in aggregate principal amount of the
Securities of such series at the time Outstanding (voting as a single class) may
on behalf of the Holders of all such Securities waive any past default or Event
of Default described in Section 5.1 and its consequences, except (i) in the
payment of the principal of or premium, if any, or interest if any, on or any
additional amounts payable in respect of any security of that Series or (ii) a
default in respect of a covenant or provision hereof which cannot be modified or
amended without the consent of the Holder of each Security affected. In the case
of any such waiver, the Issuer, the Trustee and the Holders of all such
Securities shall be restored to their former positions and rights hereunder,
respectively, and such default shall cease to exist and be deemed to have been
cured and not to have occurred for purposes of this Indenture; but no such
waiver shall extend to any subsequent or other default or impair any right
consequent thereon.

          SECTION 5.11. Trustee To Give Notice Of Default, But May Withhold In
Certain Circumstances. The Trustee shall, within 90 days after the occurrence of
a default with respect to the Securities of any series, give notice of all
defaults with respect to that series known to the Trustee to all Holders of
Securities of such series in the manner and to the extent provided in Section
313(c) of the Trust Indenture Act, unless in each case such defaults shall have
been cured before the mailing or publication of such notice (the term "default"
for the purpose of this Section being hereby defined to mean any event or
condition which is, or with notice or lapse of time or both would become, an
Event of Default); PROVIDED, that, except in the case of default in the payment
of the principal of or interest on any of the Securities of such series, or in
the payment of any sinking fund installment on such series, the Trustee shall be
protected in withholding such notice if and so long as the board of directors,
the executive committee, or a trust committee of directors or trustees and/or
Responsible Officers of the Trustee in good faith determines that the
withholding of such notice is in the interests of the Securityholders of such
series.

         The Trustee shall not be required to take notice, and shall not be
deemed to have notice, of any default or Event of Default hereunder, except
Events of Default described in paragraphs (a), (b) and (c) of Section 5.1
hereof, unless the Trustee shall be notified specifically of the default or
Event of Default in a written instrument or document delivered to it by the
Issuer or by the Holders of at least 10% of the aggregate principal amount of
Securities (or the applicable series of Securities) than outstanding. In the
absence of delivery of notice satisfying those requirements, the Trustee may
assume conclusively that there is no default or Event of Default, except as
noted above.

          SECTION 5.12. Waiver of Stay or Extension Laws. The Issuer covenants
(to the extent that it may lawfully do so) that it will not at any time insist
upon, or plead, or in any manner whatsoever claim or take the benefit or
advantage of, any stay or extension law wherever enacted, now or at any time
hereafter in force which


                                       21



may affect the covenants or the performance of this Indenture; and the Issuer
(to the extent that it may lawfully do so) hereby expressly waives all benefit
or advantage of any such law and covenants that it will not hinder, delay or
impede the execution of any power herein granted to the Trustee, but will suffer
and permit the execution of every such power as though no such law had been
enacted.

          SECTION 5.13. Right Of Court To Require Filing Of Undertaking To Pay
Costs. All parties to this Indenture agree, and each Holder of any Security by
his or her acceptance thereof shall be deemed to have agreed, that any court may
in its discretion require, in any suit for the enforcement of any right or
remedy under this Indenture or in any suit against the Trustee for any action
taken, suffered or omitted by it as Trustee, the filing by any party litigant in
such suit of an undertaking to pay the costs of such suit, and that such court
may in its discretion assess reasonable costs, including reasonable attorneys'
fees, against any party litigant in such suit, having due regard to the merits
and good faith of the claims or defenses made by such party litigant; but the
provisions of this Section shall not apply to any suit instituted by the
Trustee, to any suit instituted by any Securityholder or group of
Securityholders of any series holding in the aggregate more than 10% in
aggregate principal amount of the Securities of such series, or, in the case of
any suit relating to or arising under clause (d) or (g) of Section 5.1 (if the
suit relates to Securities of more than one but less than all series), 10% in
aggregate principal amount of Securities then Outstanding and affected thereby,
or in the case of any suit relating to or arising under clause (d) or (g) (if
the suit under clause (d) or (g) relates to all the Securities then Outstanding)
or (e) or (f) of Section 5.1, 10% in aggregate principal amount of all
Securities then Outstanding, or to any suit instituted by any Securityholder for
the enforcement of the payment of the principal of or interest on any Security
on or after the due date expressed in such Security or any date fixed for
redemption.

                                   ARTICLE VI

                             CONCERNING THE TRUSTEE

          SECTION 6.1. Duties And Responsibilities Of The Trustee; During
Default; Prior To Default. Prior to the occurrence of an Event of Default with
respect to the Securities of a particular series and after the curing or waiving
of all Events of Default which may have occurred with respect to such series,
the Trustee undertakes to perform such duties and only such duties as are
specifically set forth in this Indenture with respect to such series of
Securities. In case an Event of Default with respect to the Securities of a
series has occurred and has not been cured or waived, the Trustee shall exercise
with respect to such series of Securities such of the rights and powers vested
in it by this Indenture with respect to such series of Securities, and use the
same degree of care and skill in their exercise, as a prudent person would
exercise or use under the circumstances in the conduct of his or her own
affairs.

         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:

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

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

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


                                       22



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

(c)      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 pursuant to Section 5.9 relating to the time,
         method and place of conducting any proceeding for any remedy available
         to the Trustee, or exercising any trust or power conferred upon the
         Trustee, under this Indenture.

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

         The provisions of this Section 6.1 are in furtherance of and subject to
Section 315 of the Trust Indenture Act.

          SECTION 6.2. Certain Rights Of The Trustee. In furtherance of and
subject to the Trust Indenture Act, and subject to Section 6.1:

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

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

(c)      the Trustee may consult with counsel and any written advice or any
         Opinion of Counsel shall be full and complete authorization and

         taken by it hereunder in good faith and in reliance thereon in
         accordance with such advice or Opinion of Counsel;

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

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

(f)      prior to the occurrence of an Event of Default hereunder and after
         the curing or waiving of all Events of Default, the Trustee shall
         not be bound to make any investigation into the facts or matters
         stated in any resolution, certificate, statement, instrument,
         opinion, report, notice, request, consent, order, approval,
         appraisal, bond, debenture, note, coupon, security or other paper or
         document unless (i) requested in writing so to do by the Holders of
         not less than a majority in aggregate principal amount of the
         Securities of all series affected then Outstanding (treated as one
         class) or (ii) otherwise provided in the terms of any series of
         Securities pursuant to Section 2.3; PROVIDED, that, if the payment
         within a reasonable time to the Trustee of the costs, expenses or
         liabilities likely to be incurred by it in the making of such
         investigation is, in the opinion of the Trustee, not reasonably
         assured to the Trustee by the security afforded to it by the terms
         of this Indenture, the Trustee may require reasonable indemnity
         against such expenses or liabilities as a condition to proceeding;



                                       23


         the reasonable expenses of every such investigation shall be paid by
         the Issuer or, if paid by the Trustee or any predecessor trustee,
         shall be repaid by the Issuer upon demand; and

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

          SECTION 6.3. Trustee Not Responsible For Recitals, Disposition Of
Securities Or Application Of Proceeds Thereof. The recitals contained herein and
in the Securities, except the Trustee's certificates of authentication, shall be
taken as the statements of the Issuer, and the Trustee assumes no responsibility
for the correctness of the same. The Trustee makes no representation as to the
validity or sufficiency of this Indenture or of the Securities. The Trustee
shall not be accountable for the use or application by the Issuer of any of the
Securities or of the proceeds thereof.

          SECTION 6.4. Trustee And Agents May Hold Securities; Collections, Etc.
The Trustee or any agent of the Issuer or of the Trustee, in its individual or
any other capacity, may become the owner or pledgee of Securities with the same
rights it would have if it were not the Trustee or such agent and may otherwise
deal with the Issuer and receive, collect, hold and retain collections from the
Issuer with the same rights it would have if it were not the Trustee or such
agent.

          SECTION 6.5. Held By Trustee. Subject to the provisions of Section 9.4
hereof, all moneys received by the Trustee shall, until used or applied as
herein provided, be held in trust for the purposes for which they were received,
but need not be segregated from other funds except to the extent required by
mandatory provisions of law. Neither the Trustee nor any agent of the Issuer or
the Trustee shall be under any liability for interest on any moneys received by
it hereunder.

          SECTION 6.6. Compensation And Indemnification Of Trustee And Its Prior
Claim. The Issuer covenants and agrees to pay to the Trustee from time to time,
and the Trustee shall be entitled to reasonable compensation (which shall not be
limited by any provision of law in regard to the compensation of a trustee of an
express trust) and the Issuer covenants and agrees to pay or reimburse the
Trustee and each predecessor trustee upon its request for all reasonable
expenses, disbursements and advances incurred or made by or on behalf of it in
accordance with any of the provisions of this Indenture (including the
reasonable compensation and the expenses and disbursements of its counsel and of
all agents and other persons not regularly in its employ) except any such
expense, disbursement or advance as may arise from its negligence or bad faith.
The Issuer also covenants to indemnify the Trustee and each predecessor trustee
(and their respective directors, officers, agents and employees) for, and to
hold them harmless against, any loss, liability, fine, penalty or expense
(including out-of-pocket and incidental expenses and legal fees) incurred
without negligence or bad faith on their part, arising out of or in connection
with the acceptance or administration of this Indenture or the trusts hereunder
and its duties hereunder, including, in each case, the costs and expenses of
defending itself against or investigating any claim of liability in the
premises. The obligations of the Issuer under this Section to compensate and
indemnify the Trustee and each predecessor trustee (and their respective
directors, officers, agents and employees) and to pay or reimburse the Trustee
and each predecessor trustee for expenses, disbursements and advances shall
constitute additional indebtedness hereunder and shall survive the satisfaction
and discharge of this Indenture and the resignation or removal of the Trustee.
Such additional indebtedness shall be a senior claim to that of the Securities
upon all property and funds held or collected by the Trustee as such, except
funds held in trust for the benefit of the Holders of particular Securities and
the Securities are hereby subordinated to such senior claim.

          SECTION 6.7. Right Of Trustee To Rely On Officer's Certificate, Etc.
Subject to Sections 6.1 and 6.2, whenever in the administration of the trusts of
this Indenture the Trustee shall deem it necessary or desirable that a matter be
proved or established prior to taking or suffering or omitting any action
hereunder, such matter (unless other evidence in respect thereof be herein
specifically prescribed) may, in the absence of negligence or wilfull misconduct



                                       24


on the part of the Trustee, be deemed to be conclusively proved and established
by an Officer's Certificate delivered to the Trustee, and such certificate, in
the absence of negligence or wilfull misconduct on the part of the Trustee,
shall be full warrant to the Trustee for any action taken, suffered or omitted
by it under the provisions of this Indenture upon the faith thereof.

          SECTION 6.8. Indentures Not Creating Potential Conflicting Interests
For The Trustee. This Indenture is hereby specifically described for the
purposes of Section 310(b)(1)(i) of the Trust Indenture Act with respect to
series of Securities that are of an equal priority.

          SECTION 6.9. Qualification Of Trustee; Conflicting Interests. The
Trustee shall comply with Section 310(b) of the Trust Indenture Act.

          SECTION 6.10. Persons Eligible For Appointment As Trustee. The Trustee
for each series of Securities hereunder shall at all times be a corporation or
banking association organized and doing business under the laws of the United
States of America, any State thereof or the District of Columbia, having a
combined capital and surplus of at least $50,000,000, and which is authorized
under such laws to exercise corporate trust powers and is subject to supervision
or examination by Federal, state or District of Columbia authority. If such
corporation publishes reports of condition at least annually, pursuant to law or
to the requirements of the aforesaid 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. In case at any time the
Trustee shall cease to be eligible in accordance with the provisions of this
Section, the Trustee shall resign immediately in the manner and with the effect
specified in Section 6.11.

         The provisions of this Section 6.10 are in furtherance of and subject
to Section 310(a) of the Trust Indenture Act.

          SECTION 6.11. Resignation And Removal; Appointment Of Successor
Trustee.

      (a)   The Trustee, or any trustee or trustees hereafter appointed, may at
            any time resign with respect to one or more or all series of
            Securities by giving written notice of resignation to the Issuer and
            by mailing notice of such resignation to the Holders of then
            Outstanding Registered Securities of each series affected at their
            addresses as they shall appear on the registry books. Upon receiving
            such notice of resignation, the Issuer shall promptly appoint a
            successor trustee or trustees with respect to the applicable series
            by written instrument in duplicate, executed by authority of the
            Board of Directors, one copy of which instrument shall be delivered
            to the resigning Trustee and one copy to the successor trustee or
            trustees. If no successor trustee shall have been so appointed with
            respect to any series and have accepted appointment within 30 days
            after the mailing of such notice of resignation, the resigning
            trustee may petition any court of competent jurisdiction for the
            appointment of a successor trustee, or any Securityholder who has
            been a bona fide Holder of a Security or Securities of the
            applicable series for at least six months may, subject to the
            provisions of Section 5.12, on behalf of himself and all others
            similarly situated, petition any such court for the appointment of a
            successor trustee. Such court may thereupon, after such notice, if
            any, as it may deem proper and prescribe, appoint a successor
            trustee.

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

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

            (ii)  the Trustee shall cease to be eligible in accordance with the
                  provisions of Section 6.10 hereof and Section 310(a) of the
                  Trust Indenture Act and shall fail to resign after written
                  request therefor by the Issuer or by any Securityholder; or

            (iii) the Trustee shall become incapable of acting with respect to
                  any series of Securities, or shall be adjudged bankrupt or
                  insolvent, or a receiver or liquidator of the Trustee or of



                                       25


                  its property shall be appointed, or any public officer shall
                  take charge or control of the Trustee or of its property or
                  affairs for the purpose of rehabilitation, conservation or
                  liquidation;

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

(c)      The Holders of a majority in aggregate principal amount of the
         Securities of each series at the time outstanding may at any time
         remove the Trustee with respect to Securities of such series and
         appoint a successor trustee with respect to the Securities of such
         series by delivering to the Trustee so removed, to the successor
         trustee so appointed and to the Issuer the evidence as of the action in
         that regard taken by the Securityholders as provided for in Section
         7.1.

(d)      Any resignation or removal of the Trustee with respect to any series
         and any appointment of a successor trustee with respect to such series
         pursuant to any of the provisions of this Section 6.11 shall become
         effective upon acceptance of appointment by the successor trustee as
         provided in Section 6.12.

          SECTION 6.12. Acceptance Of Appointment By Successor Trustee. Any
successor trustee appointed as provided in Section 6.11 shall execute and
deliver to the Issuer and to its predecessor trustee an instrument accepting
such appointment hereunder, and thereupon the resignation or removal of the
predecessor trustee with respect to all or any applicable series shall become
effective and such successor trustee, without any further act, deed or
conveyance, shall become vested with all rights, powers, duties and obligations
with respect to such series of its predecessor hereunder, with like effect as if
originally named as trustee for such series hereunder; but, nevertheless, on the
written request of the Issuer or of the successor trustee, upon payment of its
charges then unpaid, the trustee ceasing to act shall, subject to Section 9.4,
pay over to the successor trustee all moneys at the time held by it hereunder
and shall execute and deliver an instrument transferring to such successor
trustee all such rights, powers, duties and obligations. Upon request of any
such successor trustee, the Issuer shall execute any and all instruments in
writing for more fully and certainly vesting in and confirming to such successor
trustee all such rights and powers. Any trustee ceasing to act shall,
nevertheless, retain a prior claim upon all property or funds held or collected
by such trustee to secure any amounts then due it pursuant to the provisions of
Section 6.6.

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

         No successor trustee with respect to any series of Securities shall
accept appointment as provided in this Section 6.12 unless at the time of such
acceptance such successor trustee shall be qualified under Section 310(b) of the
Trust Indenture Act and eligible under the provisions of Section 6.10.

         Upon acceptance of appointment by any successor trustee as provided in
this Section 6.12, the Issuer shall give notice thereof to the Holders of
Registered Securities of each series affected by mailing such notice to such
Holders at their addresses as they shall appear on the registry books. If the
acceptance of appointment is substantially contemporaneous with the resignation,
then the notice called for by the preceding sentence may be combined with the
notice called for by Section 6.11. If the Issuer fails to give such notice
within ten days after



                                       26


acceptance of appointment by the successor trustee, the successor trustee shall
cause such notice to be given at the expense of the Issuer.

          SECTION 6.13. Merger, Conversion, Consolidation Or Succession To
Business Of Trustee. Any corporation, association or other entity into which the
Trustee may be merged or converted or with which it may be consolidated, or any
corporation, association or other entity resulting from any merger, conversion
or consolidation to which the Trustee shall be a party, or any corporation,
association or other entity succeeding to the corporate trust business of the
Trustee, (including by sale or transfer of all or substantially all of its
corporate trust assets) shall be the successor of the Trustee hereunder without
the execution or filing of any paper or any further act on the part of any of
the parties hereto, anything herein to the contrary notwithstanding; PROVIDED,
that such corporation, association or other entity shall be qualified under
Section 310(b) of the Trust Indenture Act and eligible under the provisions of
Section 6.10.

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

          SECTION 6.14. Preferential Collection Of Claims Against The Issuer.
The Trustee shall comply with Section 311(a) of the Trust Indenture Act,
excluding any creditor relationship as provided in Section 311(b) of the Trust
Indenture Act. A Trustee who has resigned or been removed shall be subject to
Section 311(a) of the Trust Indenture Act to the extent indicated therein.

          SECTION 6.15. Appointment Of Authenticating Agent. As long as any
Securities of a series remain Outstanding, the Trustee may, by an instrument in
writing, appoint with the approval of the Issuer an authenticating agent (the
"Authenticating Agent") which shall be authorized to act on behalf of the
Trustee to authenticate Securities, including Securities issued upon exchange,
registration of transfer, partial redemption or pursuant to Section 2.9.
Securities of each such series authenticated by such Authenticating Agent shall
be entitled to the benefits of this Indenture and shall be valid and obligatory
for all purposes as if authenticated by the Trustee. Whenever reference is made
in this Indenture to the authentication and delivery of Securities of any series
by the Trustee or to 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 for such series and a Certificate of Authentication
executed on behalf of the Trustee by such Authenticating Agent. Such
Authenticating Agent shall at all times be a corporation organized and doing
business under the laws of the United States of America or of any State,
authorized under such laws to exercise corporate trust powers, having a combined
capital and surplus of at least $45,000,000 (determined as provided in Section
6.10 with respect to the Trustee) and subject to supervision or examination by
federal or state authority.

         Any corporation into which any 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 any Authenticating Agent
shall be a party, or any corporation succeeding to the corporate agency business
of any Authenticating Agent, shall continue to be the Authenticating Agent with
respect to all series of Securities for which it served as Authenticating Agent
without the execution or filing of any paper or any further act on the part of
the Trustee or such Authenticating Agent. Any Authenticating Agent may at any
time, and if it shall cease to be eligible shall, resign by giving written
notice of resignation to the Trustee and to the Issuer.

         Upon receiving such a notice of resignation or upon such a termination,
or in case at any time any Authenticating Agent shall cease to be eligible in
accordance with the provisions of this Section 6.15 with respect to one or more
series of Securities, the Trustee shall, upon receipt of an Issuer Order,
appoint a successor



                                       27



Authenticating Agent and the Issuer shall provide notice of such appointment to
all Holders of Securities of such series in the manner and to the extent
provided in Section 11.2. Any successor Authenticating Agent upon acceptance of
its appointment hereunder shall become vested with all rights, powers, duties
and responsibilities of its predecessor hereunder, with like effect as if
originally named as Authenticating Agent. The Issuer agrees to pay to the
Authenticating Agent for such series from time to time reasonable compensation.
The Authenticating Agent for the Securities of any series shall have no
responsibility or liability for any action taken by it as such at the direction
of the Trustee.

         Sections 6.2, 6.3, 6.4, 6.6 and 7.3 shall be applicable to any
Authenticating Agent.

                                  ARTICLE VII

                         CONCERNING THE SECURITYHOLDERS

          SECTION 7.1. Evidence Of Action Taken By Securityholders. Any request,
demand, authorization, direction, notice, consent, waiver or other action
provided by this Indenture to be given or taken by a specified percentage in
principal amount of the Securityholders of any or all series may be embodied in
and evidenced by one or more instruments of substantially similar tenor signed
by such specified percentage of Securityholders in person or by agent duly
appointed in writing; and, except as herein otherwise expressly provided, such
action shall become effective when such instrument or instruments are delivered
to the Trustee. Proof of execution of any instrument or of a writing appointing
any such agent shall be sufficient for any purpose of this Indenture, and
subject to the provisions of Sections 6.1 and 6.2, conclusive in favor of the
Trustee and the Issuer, if made in the manner provided in this Article.

         Notwithstanding the foregoing, with respect to any Registered Global
Security, nothing herein shall prevent the Issuer, the Trustee, or any agent of
the Issuer or the Trustee, from giving effect to any request, demand,
authorization, direction, notice, consent, waiver or other action provided in
this Indenture to be given or taken by a Depositary or impair, as between a
Depositary and such holders of beneficial interest, the operation of customary
practices governing the exercise of the rights of the Depositary (or its
nominee) as Holder of any Security.

         Without limiting the generality of this Section 7.1, unless otherwise
provided in or pursuant to this Indenture, a Holder, including a Depositary that
is a Holder of a Registered Global Security, may make, give or take, by a proxy
or proxies duly appointed in writing, any request, demand, authorization,
direction, notice, consent, waiver or other action provided in or pursuant to
this Indenture to be made, given or taken by Holders, and a Depositary that is a
Holder of a Registered Global Security may give its proxy or proxies to the
Depositary's participants or the beneficial owners of interests in any such
Registered Global Security, as the case may be, through such Depositary's
standing instructions and customary practices.

         The Trustee shall fix a record date for the purpose of determining the
Persons who are beneficial owners of interests in any permanent Registered
Global Security held by a Depositary and who are entitled under the procedures
of such Depositary to make, give or take, by a proxy or proxies duly appointed
in writing, any request, demand, authorization, direction, notice, consent,
waiver or other action provided in or pursuant to this Indenture to be made,
given or taken by Holders. If such a record date is fixed, the Holders on such
record date or their duly appointed proxy or proxies, and only such persons,
shall be entitled to make, give or take such request, demand, authorization,
direction, notice consent, waiver or other action, whether or not such Holders
remain Holders after such record date. No such request, demand, authorization,
direction notice, consent, waiver or other action shall be valid or effective if
made, given or taken more than 90 days after such record date.

          SECTION 7.2. Proof Of Execution Of Instruments And Of Holding Of
Securities. Subject to the provisions of Sections 6.1 and 6.2, the execution of
any instrument by a Securityholder or his or her agent or proxy may be proved in
accordance with such reasonable rules and regulations as may be prescribed by
the Trustee or in such manner as shall be satisfactory to the Trustee. The
holding of Registered Securities shall be proved by the Security register or by
a certificate of the registrar thereof.



                                       28



          SECTION 7.3. Holders To Be Treated As Owners. The Issuer, the Trustee
and any agent of the Issuer or the Trustee may deem and treat the person in
whose name any Security shall be registered upon the Security register for such
series as the absolute owner of such Security (whether or not such Security
shall be overdue and notwithstanding any notation of ownership or other writing
thereon) for the purpose of receiving payment of or on account of the principal
of and, subject to the provisions of this Indenture, interest on such Security
and for all other purposes; and neither the Issuer nor the Trustee nor any agent
of the Issuer or the Trustee shall be affected by any notice to the contrary.

         No holder of any beneficial interest in any Registered Global Security
held on its behalf by a Depositary (or its nominee) shall have any rights under
this Indenture with respect to such Registered Global Security or any Security
represented thereby, and such Depositary may be treated by the Issuer, the
Trustee, and any agent of the Issuer or the Trustee as the owner of such
Registered Global Security or any Security represented thereby for all purposes
whatsoever. None of the Issuer, the Trustee, any Paying Agent or the Security
Registrar will have any responsibility or liability for any aspect of the
records relating to or payments made on account of beneficial ownership
interests of a Registered Global Security or for maintaining, supervising or
reviewing any records relating to such beneficial ownership interests.

          SECTION 7.4. Securities Owned By Issuer Deemed Not Outstanding. In
determining whether the Holders of the requisite aggregate principal amount of
Outstanding Securities of any or all series have concurred in any request,
demand, authorization, direction, notice, consent, waiver or other action by
Securityholders under this Indenture, Securities which are owned by the Issuer
or any other obligor on the Securities with respect to which such determination
is being made or by any person directly or indirectly controlling or controlled
by or under direct or indirect common control with the Issuer or any other
obligor on the Securities with respect to which such determination is being made
shall be disregarded and deemed not to be Outstanding for the purpose of any
such determination, except that for the purpose of determining whether the
Trustee shall be protected in relying on any such action only Securities which
the Trustee knows are so owned shall be so disregarded. Securities so owned
which have been pledged in good faith may be regarded as Outstanding if the
pledgee establishes to the satisfaction of the Trustee the pledgee's right so to
act with respect to such Securities and that the pledgee is not the Issuer or
any other obligor upon the Securities or any person directly or indirectly
controlling or controlled by or under direct or indirect common control with the
Issuer or any other obligor on the Securities. In case of a dispute as to such
right, the advice of counsel shall be full protection in respect of any decision
made by the Trustee in accordance with such advice. Upon request of the Trustee,
the Issuer shall furnish to the Trustee promptly an Officer's Certificate
listing and identifying all Securities, if any, known by the Issuer to be owned
or held by or for the account of any of the above-described persons; and,
subject to the provisions of Sections 6.1 and 6.2, the Trustee shall be entitled
to accept such Officer's Certificate as conclusive evidence of the facts therein
set forth and of the fact that all Securities not listed therein are Outstanding
for the purpose of any such determination.

          SECTION 7.5. Right Of Revocation Of Action Taken. At any time prior to
(but not after) the evidencing to the Trustee, as provided in Section 7.1, of
the taking of any action by the Holders of the percentage in aggregate principal
amount of the Securities of any or all series, as the case may be, specified in
this Indenture in connection with such action, any Holder of a Security the
serial number of which is shown by the evidence to be included among the serial
numbers of the Securities the Holders of which have consented to such action
may, by filing written notice at the Corporate Trust Office and upon proof of
holding as provided in this Article, revoke such action so far as concerns such
Security. Except as aforesaid, any such action taken by the Holder of any
Security shall be conclusive and binding upon such Holder and upon all future
Holders and owners of such Security and of any Securities issued in exchange or
substitution therefor or on registration of transfer thereof, irrespective of
whether or not any notation in regard thereto is made upon any such Security.
Any action taken by the Holders of the percentage in aggregate principal amount
of the Securities of any or all series, as the case may be, specified in this
Indenture in connection with such action shall be conclusively binding upon the
Issuer, the Trustee and the Holders of all the Securities affected by such
action.

                                  ARTICLE VIII

                             SUPPLEMENTAL INDENTURES

          SECTION 8.1. Supplemental Indentures Without Consent Of
Securityholders. The Issuer, when authorized by a resolution of its Board of
Directors (which resolution may provide general terms or parameters for such
action and may provide that the specific terms of such action may be determined
in accordance with or pursuant to an Issuer Order), and the Trustee may from
time to time and at any time enter into an indenture or indentures supplemental
hereto for one or more of the following purposes:

            (a)   to evidence the succession of another corporation to the
                  Issuer, or successive successions, and the assumption by the
                  successor corporation of the covenants, agreements and
                  obligations of the Issuer pursuant to any applicable covenants
                  herein and pursuant to the terms of the Securities as set
                  forth in Section 2.3;

            (b)   to add to the covenants of the Issuer such further covenants,
                  restrictions, conditions or provisions as the Issuer and the
                  Trustee shall consider to be for the protection of the Holders
                  of Securities and to make the occurrence, or the occurrence
                  and continuance, of a default in any such additional
                  covenants, restrictions, conditions or provisions an Event of
                  Default permitting the enforcement of all or any of the
                  several remedies provided in this Indenture as herein set
                  forth; PROVIDED, that in respect of any such additional
                  covenant, restriction, condition or provision such
                  supplemental indenture may provide for a particular period of
                  grace after default (which period may be shorter or longer
                  than that allowed in the case of other defaults) or may
                  provide for an immediate enforcement upon such an Event of
                  Default or may limit the remedies available to the Trustee
                  upon such an Event of Default or may limit the right of the
                  Holders of a majority in aggregate principal amount of the
                  Securities of such series to waive such an Event of Default;
                  PROVIDED FURTHER, that any such addition, change or
                  elimination (i) shall neither (A) apply to any Security of any
                  series created prior to the execution of such supplemental
                  indenture and entitled to the benefit of such provision and
                  (ii) shall become effective only when there is no such
                  Security Outstanding.

            (c)   to cure any ambiguity or to correct or supplement any
                  provision contained herein or in any supplemental indenture
                  which may be defective or inconsistent with any other
                  provision contained herein or in any supplemental indenture,
                  or to make any other provisions as the Issuer may deem
                  necessary or desirable, PROVIDED, that no such action shall
                  adversely affect the interests of the Holders of the
                  Securities in any material respect as determined by the
                  Trustee (which determination may be based on an Opinion of
                  Counsel); and

            (d)   to evidence and provide for the acceptance of appointment
                  hereunder by a successor trustee with respect to the
                  Securities of one or more series and to add to or change any
                  of the provisions of this Indenture as shall be necessary to
                  provide for or facilitate the administration of the trusts
                  hereunder by more than one trustee, pursuant to the
                  requirements of Section 6.12.

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

         Any supplemental indenture authorized by the provisions of this Section
may be executed without the consent of the Holders of any of the Securities at
the time outstanding, notwithstanding any of the provisions of Section 8.2.

          SECTION 8.2. Supplemental Indentures With Consent Of Securityholders.



                                       30



(a)   Except as set forth in paragraph (b) below, with the consent (evidenced as
      provided in Article VII) of the Holders of not less than a majority in
      aggregate principal amount of the Securities at the time Outstanding of
      all series of Securities affected by such supplemental indenture (voting
      as one class), the Issuer, when authorized by a resolution of its Board of
      Directors (which resolution may provide general terms or parameters for
      such action and may provide that the specific terms of such action may be
      determined in accordance with or pursuant to an Issuer Order), and the
      Trustee may, from time to time and at any time, enter into an indenture or
      indentures supplemental hereto (which shall conform to the provisions of
      the Trust Indenture Act as in force and effect at the date of execution
      thereof) for the purpose of adding any provisions to or changing in any
      manner or eliminating any of the provisions of this Indenture or of any
      supplemental indenture or of modifying in any manner the rights of the
      Holders of the Securities of each such series.

(b)   No such supplemental indenture shall (i) extend the final maturity of any
      Security, or reduce the principal amount thereof, or reduce the rate or
      extend the time of payment of interest thereon, or reduce any amount
      payable on redemption thereof, or make the principal thereof (including
      any amount in respect of original issue discount), or interest thereon
      payable in any coin or currency other than that provided in the Securities
      or in accordance with the terms thereof, or reduce the amount of the
      principal of an Original Issue Discount Security that would be due and
      payable upon an acceleration of the maturity thereof pursuant to Section
      5.1 or the amount thereof provable in bankruptcy pursuant to Section 5.2,
      or impair or affect the right of any Securityholder to institute suit for
      the payment thereof when due or, if the Securities provide therefor, any
      right of repayment at the option of the Securityholder, in each case
      without the consent of the Holder of each Security so affected, or (ii)
      reduce the aforesaid percentage of Securities of any series, the consent
      of the Holders of which is required for any such supplemental indenture,
      without the consent of the Holders of each Security so affected.

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

(d)   Upon the request of the Issuer, accompanied by a copy of a resolution of
      the Board of Directors (which resolution may provide general terms or
      parameters for such action and may provide that the specific terms of such
      action may be determined in accordance with or pursuant to an Issuer
      Order) certified by the secretary or an assistant secretary of the Issuer
      authorizing the execution of any such supplemental indenture, and upon the
      filing with the Trustee of evidence of the consent of the Holders of the
      Securities as aforesaid and other documents, if any, required by Section
      7.1, the Trustee shall join with the Issuer in the execution of such
      supplemental indenture unless such supplemental indenture affects the
      Trustee's own rights, duties or immunities under this Indenture or
      otherwise, in which case the Trustee may in its discretion, but shall not
      be obligated to, enter into such supplemental indenture.

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

         Promptly after the execution by the Issuer and the Trustee of any
supplemental indenture pursuant to the provisions of this Section 8.2, the
Trustee shall give notice thereof to the Holders of then Outstanding Registered
Securities of each series affected thereby, by mailing a notice thereof by
first-class mail to such Holders at their addresses as they shall appear on the
Security register, and such notice shall set forth in general terms the
substance of such supplemental indenture. Any failure of the Issuer to give such
notice, or any defect therein, shall not, however, in any way impair or affect
the validity of any such supplemental indenture.

          SECTION 8.3. Effect Of Supplemental Indenture. Upon the execution of
any supplemental indenture pursuant to the provisions hereof, this Indenture
shall be and be deemed to be modified and amended in accordance therewith and
the respective rights, limitations of rights, obligations, duties and immunities
under this Indenture of


                                       31



the Trustee, the Issuer and the Holders of Securities of each series affected
thereby shall thereafter be determined, exercised and enforced hereunder subject
in all respects to such modifications and amendments, and all the terms and
conditions of any such supplemental indenture shall be and be deemed to be part
of the terms and conditions of this Indenture for any and all purposes.

          SECTION 8.4. Documents To Be Given To Trustee. The Trustee, subject to
the provisions of Sections 6.1 and 6.2, shall be entitled to receive, and shall
be fully protected in relying upon, an Officer's Certificate and an Opinion of
Counsel as conclusive evidence that any supplemental indenture executed pursuant
to this Article VIII complies with the applicable provisions of this Indenture.

          SECTION 8.5. Notation On Securities In Respect Of Supplemental
Indentures. Securities of any series authenticated and delivered after the
execution of any supplemental indenture pursuant to the provisions of this
Article may bear a notation in form approved by the Trustee for such series as
to any matter provided for by such supplemental indenture or as to any action
taken by Securityholders. If the Issuer or the Trustee shall so determine, new
Securities of any series so modified as to conform, in the opinion of the
Trustee and the Board of Directors, to any modification of this Indenture
contained in any such supplemental indenture may be prepared by the Issuer,
authenticated by the Trustee and delivered in exchange for the Securities of
such series then Outstanding.

                                   ARTICLE IX

                    SATISFACTION AND DISCHARGE OF INDENTURE;
                                UNCLAIMED MONEYS

          SECTION 9.1. Satisfaction And Discharge Of Indenture.

(a)   The following provisions shall apply to the Securities of each series
      unless specifically otherwise provided in a Board Resolution, Officer's
      Certificate or supplemental indenture provided pursuant to Section 2.3. If
      at any time (i) the Issuer shall have paid or caused to be paid the
      principal of and interest on all the Securities of any series Outstanding
      hereunder and (other than Securities of such series which have been
      destroyed, lost or stolen and which have been replaced or paid as provided
      in Section 2.9) as and when the same shall have become due and payable, or
      (ii) the Issuer shall have delivered to the Trustee for cancellation all
      Securities of any series theretofore authenticated (other than any
      Securities of such series which shall have been destroyed, lost or stolen
      and which shall have been replaced or paid as provided in Section 2.9) or
      (iii) in the case of any series of Securities where the exact amount of
      principal of and interest due on which can be determined at the time of
      making the deposit referred to in clause (b) below, (a) all the Securities
      of such series not theretofore delivered to the Trustee for cancellation
      shall have become due and payable, or are by their terms to become due and
      payable within one year or are to be called for redemption within one year
      under arrangements satisfactory to the Trustee for the giving of notice of
      redemption, and (b) the Issuer shall have irrevocably deposited or caused
      to be deposited with the Trustee funds in trust the entire amount in (i)
      cash (other than moneys repaid by the Trustee or any paying agent to the
      Issuer in accordance with Section 9.4), (ii) direct obligations of the
      United States of America or obligations of a Person controlled or
      supervised by and acting as an agency or instrumentality of the United
      States, the payment of which is unconditionally guaranteed as a full faith
      and credit obligation of the United States, which are not callable or
      redeemable at the option of the issuer thereof ("U.S. Government
      Obligations"), maturing as to principal and interest at such times and in
      such amounts as will insure the availability of cash sufficient to pay at
      such maturity or upon such redemption, as the case may be, or (iii) a
      combination thereof, sufficient, in the opinion of a nationally recognized
      firm of independent public accountants expressed in a written
      certification thereof delivered to the Trustee, to pay (x) the principal
      and interest on all Securities of such series on each date that such
      principal or interest is due and payable and (y) any mandatory sinking
      fund payments on the dates on which such payments are due and payable in
      accordance with the terms of the Indenture and the Securities of such
      series; and if, in any such case, the Issuer shall also pay or cause to be
      paid all other sums payable hereunder by the Issuer, then this Indenture
      shall cease to be of further effect (except as to (i) rights of
      registration of transfer and exchange of Securities of such Series
      pursuant to Section 2.8 and the Issuer's right of optional redemption, if
      any, (ii) substitution of mutilated, defaced, destroyed, lost or stolen
      Securities (iii) rights of holders of Securities



                                       32



      pursuant to Section 2.8 to receive payments of principal thereof and
      interest thereon, upon the original stated due dates therefor (but not
      upon acceleration), and remaining rights of the Holders to receive
      mandatory sinking fund payments, if any, (iv) the rights, obligations,
      duties and immunities of the Trustee hereunder, including those under
      Section 6.6, (v) the rights of the Holders of Securities of such series
      as beneficiaries hereof with respect to the property so deposited with
      the Trustee payable to all or any of them, and (vi) the obligations of
      the Issuer under Section 3.2) and the Trustee, on demand of the Issuer
      accompanied by an Officer's Certificate and an Opinion of Counsel and at
      the cost and expense of the Issuer, shall execute proper instruments
      acknowledging such satisfaction of and discharging this Indenture;
      PROVIDED, that the rights of Holders of the Securities to receive
      amounts in respect of principal of and interest on the Securities held
      by them shall not be delayed longer than required by then-applicable
      mandatory rules or policies of any securities exchange upon which the
      Securities are listed. The Issuer agrees to reimburse the Trustee for
      any costs or expenses thereafter reasonably and properly incurred and to
      compensate the Trustee for any services thereafter reasonably and
      properly rendered by the Trustee in connection with this Indenture or
      the Securities of such series.

(b)   The following provisions shall apply to the Securities of each series
      unless specifically otherwise provided in a Board Resolution, Officer's
      Certificate or supplemental indenture provided pursuant to Section 2.3. In
      addition to discharge of the Indenture pursuant to the next preceding
      paragraph, in the case of any series of Securities the exact amounts of
      principal of and interest due on which can be determined at the time of
      making the deposit referred to in clause (a) below, the Issuer shall be
      deemed to have paid and discharged the entire indebtedness on all the
      Securities of such a series on the date of the deposit referred to in
      subparagraph (a) below, and the provisions of this Indenture with respect
      to the Securities of such series shall no longer be in effect (except as
      to (i) rights of registration of transfer and exchange of Securities of
      such series pursuant to Section 2.8 and the Issuer's right of optional
      redemption, if any, (ii) substitution of mutilated, defaced, destroyed,
      lost or stolen Securities, (iii) rights of Holders of Securities to
      receive payments of principal thereof and interest thereon, upon the
      original stated due dates therefor (but not upon acceleration), and
      remaining rights of the Holders to receive mandatory sinking fund
      payments, if any, (iv) the rights, obligations, duties and immunities of
      the Trustee hereunder, (v) the rights of the Holders of Securities of such
      series as beneficiaries hereof with respect to the property so deposited
      with the Trustee payable to all or any of them and (vi) the obligations of
      the Issuer under Section 3.2) and the Trustee, at the expense of the
      Issuer, shall at the Issuer's request, execute proper instruments
      acknowledging the same, if:

      (i)   with reference to this provision the Issuer has irrevocably
            deposited or caused to be irrevocably deposited with the Trustee as
            funds in trust, specifically pledged as security for, and dedicated
            solely to, the benefit of the Holders of the Securities of such
            series: (x) cash in an amount, or (y) U.S. Government Obligations,
            maturing as to principal and interest at such times and in such
            amounts as will insure the availability of cash or (z) a combination
            thereof, sufficient, in the opinion of a nationally recognized firm
            of independent public accountants expressed in a written
            certification thereof delivered to the Trustee, to pay (A) the
            principal and interest on all Securities of such series on each date
            that such principal or interest is due and payable and (B) any
            mandatory sinking fund payments on the dates on which such payments
            are due and payable in accordance with the terms of the Indenture
            and the Securities of such series;

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

      (iii) the Issuer has delivered to the Trustee an opinion of counsel from a
            nationally recognized law firm based on the fact that (x) the Issuer
            has received from, or there has been published by, the IRS a ruling
            or (y) since the date hereof, there has been a change in the
            applicable United States federal income tax law, in either case to
            the effect that, and such opinion shall confirm that, the Holders of
            the Securities of such series will not recognize income, gain or
            loss for United States federal income tax purposes as a result of
            such deposit, defeasance and discharge and will be subject to United
            States 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;



                                       33



      (iv)  the Issuer has delivered to the Trustee an Opinion of Counsel to the
            effect that after the 91st day following the deposit, the trust
            funds will not be subject to avoidance as a preferential transfer
            under Section 547(b) of the United States Bankruptcy Code (except
            with respect to any Holder that is an "insider" of the Issuer within
            the meaning of the United States Bankruptcy Code); and

      (v)   the Issuer has delivered to the Trustee an Officer's Certificate and
            an Opinion of Counsel, each stating that all conditions precedent
            provided for relating to the defeasance contemplated by this
            provision have been complied with.


(c)   If the trustee or any paying agent is unable to apply any money in
      accordance with this Indenture by reason of any order or judgment of any
      court or governmental authority enjoining, restraining or otherwise
      prohibiting that application, then the Issuer's obligations under this
      Indenture and the Securities shall be revived and reinstated as though no
      deposit had occurred pursuant to this Indenture, until such time as the
      Trustee or paying agent is permitted to apply all money in accordance with
      this Indenture; provided, however, that if the Issuer makes any payment of
      principal of (or premium, if any) or interest, if any, on any Security
      following the reinstatement of such obligations, the Issuer will be
      subrogated to the rights of the Holders to receive such payment from the
      money held by the Trustee or paying agent.

(d)   The Issuer shall be released from its obligations under Sections 3.6 and
      3.7 and unless otherwise provided for in the Board Resolution and/or
      Officer's Certificate establishing such series of Securities, from all
      covenants and other obligations referred to in Section 2.3(14) or 2.3(15)
      with respect to such series of Securities, outstanding on and after the
      date the conditions set forth below are satisfied (hereinafter, "covenant
      defeasance"). For this purpose, such covenant defeasance means that, with
      respect to the Outstanding Securities of any series, the Issuer may omit
      to comply with and shall have no liability in respect of any term,
      condition or limitation set forth in such Section, whether directly or
      indirectly by reason of any reference elsewhere herein to such Section or
      by reason of any reference in such Section to any other provision herein
      or in any other document and such omission to comply shall not constitute
      an Event of Default under Section 5.1, but the remainder of this Indenture
      and such Securities shall be unaffected thereby. The following shall be
      the conditions to application of this subsection (d) of this Section 9.1,
      unless otherwise provided for in the Board Resolution and/or Officer's
      Certificate establishing such series of Securities:

      (i)   The Issuer has irrevocably deposited or caused to be deposited with
            the Trustee as trust funds in trust for the purpose of making the
            following payments, specifically pledged as security for, and
            dedicated solely to, the benefit of the holders of the Securities of
            such series, (i) cash in an amount, or (ii) U.S. Government
            Obligations maturing as to principal and interest at such times and
            in such amounts as will insure the availability of cash or (iii) a
            combination thereof, sufficient, in the opinion of a nationally
            recognized firm of independent public accountants expressed in a
            written certification thereof delivered to the Trustee, to pay (A)
            the principal and interest on all Securities of such series and (B)
            any mandatory sinking fund payments on the day on which such
            payments are due and payable in accordance with the terms of the
            Indenture and the Securities of such series;

      (ii)  No Event of Default or event which with notice or lapse of time or
            both would become an Event of Default with respect to the Securities
            shall have occurred and be continuing on the date of such deposit;

      (iii) Such covenant defeasance shall not cause the Trustee to have a
            conflicting interest as defined in Section 6.9 or for purposes of
            the Trust Indenture Act with respect to any securities of the
            Issuer;

      (iv)  Such covenant defeasance shall not result in a breach or violation
            of, or constitute a default under any agreement or instrument to
            which the Issuer is a party or by which it is bound;

                                       34




      (v)   Such covenant defeasance shall not cause any Securities then listed
            on any registered national securities exchange under the Exchange
            Act to be delisted;

      (vi)  The Issuer shall have delivered to the Trustee an Officer's
            Certificate and an opinion of counsel from a nationally recognized
            law firm to the effect that the Holders of the Securities of such
            series will not recognize income, gain or loss for United States
            federal income tax purposes as a result of such covenant defeasance
            and will be subject to United States 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;

      (vii) The Issuer has delivered to the Trustee an Opinion of Counsel to the
            effect that after the 91st day following the deposit, the trust
            funds will not be subject to avoidance as a preferential transfer
            under Section 547(b) of the United States Bankruptcy Code (except
            with respect to any Holder that is an "insider" of the Issuer within
            the meaning of the United States Bankruptcy Code); and

      (viii) The Issuer shall have delivered to the Trustee an Officer's
            Certificate and an Opinion of Counsel, each stating that all
            conditions precedent provided for relating to the covenant
            defeasance contemplated by this provision have been complied with.

      SECTION 9.2. Application By Trustee Of Funds Deposited For Payment Of
Securities. Subject to Section 9.4, all moneys deposited with the Trustee (or
other trustee) pursuant to Section 9.1 shall be held in trust and applied by it
to the payment, either directly or through any paying agent (including the
Issuer acting as its own paying agent), to the Holders of the particular
Securities of such series for the payment or redemption of which such moneys
have been deposited with the Trustee, of all sums due and to become due thereon
for principal and interest; but such money need not be segregated from other
funds except to the extent required by law.

      SECTION 9.3. Repayment Of Moneys Held By Paying Agent. In connection with
the satisfaction and discharge of this Indenture with respect to Securities of
any series, all moneys then held by any paying agent under the provisions of
this Indenture with respect to such series of Securities shall, upon demand of
the Issuer, be repaid to it or paid to the Trustee and thereupon such paying
agent shall be released from all further liability with respect to such moneys.

      SECTION 9.4. Return Of Moneys Held By Trustee And Paying Agent Unclaimed
For Two Years. Any moneys deposited with or paid to the Trustee or any paying
agent for the payment of the principal of or interest on any Security of any
series and not applied but remaining unclaimed for two years after the date upon
which such principal or interest shall have become due and payable, shall, upon
the written request of the Issuer and unless otherwise required by mandatory
provisions of applicable escheat or abandoned or unclaimed property law, be
repaid to the Issuer by the Trustee for such series or such paying agent, and
the Holder of the Securities of such series shall, unless otherwise required by
mandatory provisions of applicable escheat or abandoned or unclaimed property
laws, thereafter look only to the Issuer for any payment which such Holder may
be entitled to collect, and all liability of the Trustee or any paying agent
with respect to such moneys shall thereupon cease; PROVIDED, that the Trustee or
such paying agent, before being required to make any such repayment with respect
to moneys deposited with it for any payment shall at the expense of the Issuer,
mail by first-class mail to Holders of such Securities at their addresses as
they shall appear on the Security register, notice that such moneys remain and
that, after a date specified therein, which shall not be less than 30 days from
the date of such mailing or publication, any unclaimed balance of such money
then remaining will be repaid to the Issuer.

      SECTION 9.5. Indemnity For U.S. Government Of Obligations. The Issuer
shall pay and indemnify the Trustee against any tax, fee or other charge imposed
on or assessed against the U.S. Government Obligations deposited pursuant to
Section 9.1 or the principal or interest received in respect of such
obligations.

                            MISCELLANEOUS PROVISIONS

      SECTION 10.1. Incorporators, Shareholders, Officers And Directors Of
Issuer Exempt From Individual Liability. No recourse under or upon any
obligation, covenant or agreement contained in this Indenture, or in any
Security, or because of any indebtedness evidenced thereby, shall be had against
any incorporator, as such, or against any past, present or future shareholder,
officer or director, as such, of the Issuer or of any successor, either directly
or through the Issuer or any successor, under any rule of law, statute or
constitutional provision or by the enforcement of any assessment or by any legal
or equitable proceeding or otherwise, all such liability being expressly waived
and released by the acceptance of the Securities by the Holders thereof and as
part of the consideration for the issue of the Securities.

      SECTION 10.2. Provisions Of Indenture For The Sole Benefit Of Parties And
Holders Of Securities. Nothing in this Indenture, in the Securities, expressed
or implied, shall give or be construed to give to any person, firm or
corporation, other than the parties thereto and their successors and the Holders
of the Securities any legal or equitable right, remedy or claim under this
Indenture or under any covenant or provision herein contained, all such
covenants and provisions being for the sole benefit of the parties hereto and
their successors and of the Holders of the Securities.

      SECTION 10.3. Successors And Assigns Of Issuer Bound By Indenture. All the
covenants, stipulations, promises and agreements in this Indenture contained by
or in behalf of the Issuer shall bind its successors and assigns, whether so
expressed or not.

      SECTION 10.4. Notices And Demands On Issuer, Trustee And Holders Of
Securities. Any notice or demand which by any provision of this Indenture is
required or permitted to be given or served by the Trustee or by the Holders of
Securities to or on the Issuer may be given or served by being deposited postage
prepaid, first-class mail (except as otherwise specifically provided herein)
addressed (until another address of the Issuer is filed by the Issuer with the
Trustee) to Exelon Corporation, 10 South Dearborn Street, 37th Floor, Post
Office Box A-3005, Chicago, Illinois 60690-3005, Attention: Secretary. Any
notice, direction, request or demand by the Issuer or any Holder of Securities
to or upon the Trustee shall be deemed to have been sufficiently given or served
by being deposited postage prepaid, first-class mail (except as otherwise
specifically provided herein) addressed (until another address of the Trustee is
filed by the Trustee with the Issuer) to, 250 W. Huron Road, Suite 220,
Cleveland, Ohio 44113 Attention: Corporate Trust Department.

         Where this Indenture provides for notice to Holders of Registered
Securities, such notice shall be sufficiently given (unless otherwise herein
expressly provided) if in writing and mailed, first-class mail, postage prepaid,
to each Holder entitled thereto, at his or her last address as it appears in the
Security register.

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

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

      SECTION 10.5. Officer's Certificates And Opinions Of Counsel; Statements
To Be Contained Therein. Upon any application or demand by the Issuer to the
Trustee to take any action under any of the provisions of this Indenture, the
Issuer shall furnish to the Trustee an Officer's Certificate stating that all
conditions precedent provided for in this Indenture relating to the proposed
action have been complied with and an Opinion of Counsel


                                       36



stating that in the opinion of such counsel all such conditions precedent have
been complied with, except that in the case of any such application or demand as
to which the furnishing of such documents is specifically required by any
provision of this Indenture relating to such particular application or demand,
no additional certificate or opinion need be furnished.

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

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

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

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

      SECTION 10.6. Payments Due On Saturdays, Sundays And Holidays. If the date
of maturity of interest on or principal of the Securities of any series or the
date fixed for redemption or repayment of any such Security shall not be a
Business Day, then payment of interest or principal need not be made on such
date, but may be made on the next succeeding Business Day with the same force
and effect as if made on the date of maturity or the date fixed for redemption,
and no interest shall accrue for the period after such date.

      SECTION 10.7. Conflict Of Any Provision Of Indenture With Trust Indenture
Act. If and to the extent that any provision of this Indenture limits, qualifies
or conflicts with duties imposed by, or with another provision (an "incorporated
provision") included in this Indenture by operation of Sections 310 to 318,
inclusive, of the Trust Indenture Act, such imposed duties or incorporated
provision shall control.

      SECTION 10.8. PENNSYLVANIA LAW TO GOVERN. THIS INDENTURE AND EACH SECURITY
SHALL BE DEEMED TO BE A CONTRACT UNDER THE LAWS OF THE COMMONWEALTH OF
PENNSYLVANIA, AND FOR ALL PURPOSES SHALL BE CONSTRUED IN ACCORDANCE WITH THE
LAWS OF SUCH COMMONWEALTH.

      SECTION 10.9. Counterparts. This Indenture may be executed in any number
of counterparts, each of which shall be an original; but such counterparts shall
together constitute but one and the same instrument.

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



                                       37



                                   ARTICLE XI

                   REDEMPTION OF SECURITIES AND SINKING FUNDS

      SECTION 11.1. Applicability Of Article. The provisions of this Article
shall be applicable to the Securities of any series which are redeemable before
their maturity or to any sinking fund for the retirement of Securities of a
series except as otherwise specified as contemplated by Section 2.3 for
Securities of such series.

      SECTION 11.2. Notice Of Redemption; Partial Redemptions. Notice of
redemption to the Holders of Registered Securities of any series to be redeemed
as a whole or in part at the option of the Issuer shall be given by mailing
notice of such redemption by first class mail, postage prepaid, at least 30 days
and not more than 60 days prior to the date fixed for redemption to such Holders
of Securities of such series at their last addresses as they shall appear upon
the registry books. Any notice which is mailed in the manner herein provided
shall be conclusively presumed to have been duly given, whether or not the
Holder receives the notice. Failure to give notice by mail, or any defect in the
notice to the Holder of any Security of a series designated for redemption as a
whole or in part shall not affect the validity of the proceedings for the
redemption of such Security of such series.

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

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

      On or before the redemption date specified in the notice of redemption
given as provided in this Section, the Issuer will deposit with the Trustee or
with one or more paying agents (or, if the Issuer is acting as its own paying
agent, set aside, segregate and hold in trust as provided in Section 3.4) an
amount of money sufficient to redeem on the redemption date all the Securities
of such series so called for redemption at the appropriate redemption price,
together with accrued interest to the date fixed for redemption. The Issuer will
deliver to the Trustee at least 70 days prior to the date fixed for redemption,
or such shorter period as shall be acceptable to the Trustee, an Officer's
Certificate stating the aggregate principal amount of Securities to be redeemed.
In case of a redemption at the election of the Issuer prior to the expiration of
any restriction on such redemption, the Issuer shall deliver to the Trustee,
prior to the giving of any notice of redemption to Holders pursuant to this
Section, an Officer's Certificate stating that such restriction has been
complied with.

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

      SECTION 11.3. Payment Of Securities Called For Redemption. If notice of
redemption has been given as above provided, the Securities or portions of
Securities specified in such notice shall become due and


                                       38



payable on the date and at the place stated in such notice at the applicable
redemption price, together with interest accrued to the date fixed for
redemption, and on and after said date (unless the Issuer shall default in the
payment of such Securities at the redemption price, together with interest
accrued to said date) interest on the Securities or portions of Securities so
called for redemption shall cease to accrue, and, except as provided in Sections
6.5 and 9.4, such Securities shall cease from and after the date fixed for
redemption to be entitled to any benefit or security under this Indenture, and
the Holders thereof shall have no right in respect of such Securities except the
right to receive the redemption price thereof and unpaid interest to the date
fixed for redemption. On presentation and surrender of such Securities at a
place of payment specified in said notice, said Securities or the specified
portions thereof shall be paid and redeemed by the Issuer at the applicable
redemption price, together with interest accrued thereon to the date fixed for
redemption; PROVIDED, that payment of interest becoming due on or prior to the
date fixed for redemption shall be payable to the Holder of such Registered
Securities registered as such on the relevant record date, subject to the terms
and provisions of Section 2.3 and 2.7 hereof.

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

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

      SECTION 11.4. Exclusion Of Certain Securities From Eligibility For
Selection For Redemption. Securities shall be excluded from eligibility for
selection for redemption if they are identified by registration and certificate
number in an Officer's Certificate delivered to the Trustee at least 40 days
prior to the last date on which notice of redemption may be given as being owned
of record and beneficially by, and not pledged or hypothecated by, either (a)
the Issuer or (b) an entity specifically identified in such written statement as
directly or indirectly controlling or controlled by or under direct or indirect
common control with the Issuer.

      SECTION 11.5. Mandatory And Optional Sinking Funds. The minimum amount of
any sinking fund payment provided for by the terms of the 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 the
Securities of any series is herein referred to as an "optional sinking fund
payment." The date on which a sinking fund payment is to be made is herein
referred to as the "sinking fund payment date."

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

      On or before the 60th day next preceding each sinking fund payment date
for any series, the Issuer will deliver to the Trustee an Officer's Certificate
(which need not contain the statements required by Section 10.5) (a) specifying
the portion of the mandatory sinking fund payment to be satisfied by payment of
cash and the portion to be satisfied by credit of Securities of such series and
the basis for such credit, (b) stating that none of the Securities of such
series has theretofore been so credited, (c) stating that no defaults in the
payment of interest or Events of Default with respect to such series have
occurred (which have not been waived or cured) and are continuing and (d)
stating whether or not the Issuer intends to exercise its right to make an
optional sinking fund payment with respect to such series and, if so, specifying
the amount of such optional sinking fund payment which the Issuer intends to pay
on or before the next succeeding sinking fund payment date. Any Securities of
such series to be credited and required to be delivered to the Trustee in order
for the Issuer to be entitled to credit therefor as aforesaid which have


                                       39



not theretofore been delivered to the Trustee shall be delivered for
cancellation pursuant to Section 2.10 to the Trustee with such Officer's
Certificate (or reasonably promptly thereafter if acceptable to the Trustee).
Such Officer's Certificate shall be irrevocable and upon its receipt by the
Trustee, the Issuer shall become unconditionally obligated to make all the cash
payments or payments therein referred to, if any, on or before the next
succeeding sinking fund payment date. Failure of the Issuer, on or before any
such 60th day, to deliver such Officer's Certificate and Securities specified in
this paragraph, if any, shall not constitute a default but shall constitute, on
and as of such date, the irrevocable election of the Issuer (i) that the
mandatory sinking fund payment for such series due on the next succeeding
sinking fund payment date shall be paid entirely in cash without the option to
deliver or credit Securities of such series in respect thereof and (ii) that the
Issuer will make no optional sinking fund payment with respect to such series as
provided in this Section.

         If the sinking fund payment or payments (mandatory or optional or both)
to be made in cash on the next succeeding sinking fund payment date plus any
unused balance of any preceding sinking fund payments made in cash shall exceed
$50,000 or a lesser sum in Dollars if the Issuer shall so request with respect
to the Securities of any particular series, such cash shall be applied on the
next succeeding sinking fund payment date to the redemption of Securities of
such series at the sinking fund redemption price together with accrued interest
to the date fixed for redemption. If such amount shall be $50,000 or less and
the Issuer makes no such request then it shall be carried over until a sum in
excess of $50,000 is available. The Trustee shall select, in the manner provided
in Section 11.2, for redemption on such sinking fund payment date a sufficient
principal amount of Securities of such series to absorb said cash, as nearly as
may be, and shall (if requested in writing by the Issuer) inform the Issuer of
the serial numbers of the Securities of such series (or portions thereof) so
selected. Securities shall be excluded from eligibility for redemption under
this Section if they are identified by registration and certificate number in an
Officer's Certificate delivered to the Trustee at least 60 days prior to the
sinking fund payment date as being owned of record and beneficially by, and not
pledged or hypothecated by, either (a) the Issuer or (b) an entity specifically
identified in such Officer's Certificate as directly or indirectly controlling
or controlled by or under direct or indirect common control with the Issuer. The
Trustee, in the name and at the expense of the Issuer (or the Issuer, if it
shall so request the Trustee in writing) shall cause notice of redemption of the
Securities of such series to be given in substantially the manner provided in
Section 11.2 (and with the effect provided in Section 11.3) for the redemption
of Securities of such series in part at the option of the Issuer. The amount of
any sinking fund payments not so applied or allocated to the redemption of
Securities of such series shall be added to the next cash sinking fund payment
for such series and, together with such payment, shall be applied in accordance
with the provisions of this Section. Any and all sinking fund moneys held on the
stated maturity date of the Securities of any particular series (or earlier, if
such maturity is accelerated), which are not held for the payment or redemption
of particular Securities of such series shall be applied, together with other
moneys, if necessary, sufficient for the purpose, to the payment of the
principal of, and interest on, the Securities of such series at maturity.

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

      The Trustee shall not redeem or cause to be redeemed any Securities of a
series with sinking fund moneys or give any notice of redemption of Securities
for such series by operation of the sinking fund during the continuance of a
default in payment of interest on such Securities or of any Event of Default
except that, where the giving of notice of redemption of any Securities shall
theretofore have been made, the Trustee shall redeem or cause to be redeemed
such Securities, provided that it shall have received from the Issuer a sum
sufficient for such redemption. Except as aforesaid, any moneys in the sinking
fund for such series at the time when any such default or Event of Default shall
occur, and any moneys thereafter paid into the sinking fund, shall, during the
continuance of such default or Event of Default be deemed to have been collected
under Article V and held for the payment of all such Securities. In case such
Event of Default shall have been waived as provided in Section 5.10 or the
default cured on or before the 60th day preceding the sinking fund payment date
in any year, such moneys shall thereafter be applied on the next succeeding
sinking fund payment date in accordance with this Section to the redemption of
such Securities.
