deducted and, if so, whether the Company will have the option to redeem the
Securities of the series rather than pay such additional amounts;

          (16) 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;

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

                                       9
<PAGE>

          (18) any additional events of default or covenants with respect to the
Securities of a particular series not set forth herein;

          (19) the terms and conditions, if any, upon which any Securities of
such series may or shall be converted or exchanged into other instruments or
other forms of property of the Company or its subsidiaries, including without
limitation, securities of another Person held by the Company or its Affiliates,
and if so the terms thereof; and

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

     (b)  All Securities of any one series and Coupons, if any, appertaining
thereto shall be substantially identical except that any series may have serial
maturities and different interest rates for different maturities and except in
the case of Registered Securities as to denomination and the differences herein
specified between Registered Global Securities and Registered Securities issued
in definitive form and except as may otherwise be provided in or pursuant to
such Board Resolution and set forth in such Officer's Certificate or
Supplemental Indenture relating to such series of Securities.  All Securities of
any one series need not be issued at the same time, and, unless otherwise
provided in the Officer's Certificate or Supplemental Indenture relating to such
series, a series may be reopened for issuances of additional Securities of such
series.

     SECTION 2.04.  Authentication and Delivery of Indentures.
                    -----------------------------------------

          At any time and from time to time after the execution and delivery of
this Indenture, the Company may deliver any series of Securities having attached
thereto appropriate Coupons, if any, executed by the Company to the Trustee for
authentication by it together with the applicable documents referred to below in
this Section 2.04, and the Trustee shall thereupon authenticate and deliver said
Securities (or if only a single Security, such Security) and Coupons, if any, to
or upon the written order of the Company, signed by an officer of the Company,
without any further corporate action.  The maturity date, original issue date,
interest rate and any other terms of the Securities of such series and Coupons,
if any, appertaining thereto shall be determined by or pursuant to such Company
Order and procedures.  If provided for in such procedures, such Company Order
may authorize authentication and delivery pursuant to oral or electronic
instructions from the Company 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 Company to the Trustee to
authenticate Securities of such series) and (subject to Section 7.01) shall be
fully protected in relying upon, the following enumerated documents unless and
until such documents have been superseded or revoked:

          (1)  a Company Order requesting such authentication and setting forth
delivery instructions if the Securities and Coupons, if any, are not to be
delivered to the Company, provided that, with respect to Securities of a series
subject to a Periodic Offering, (a) such Company Order may be delivered by the
Company to the Trustee prior to the delivery to the Trustee of such Securities
for authentication and delivery, (b) the Trustee shall authenticate and

                                       10
<PAGE>

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 a Company Order or pursuant to
procedures acceptable to the Trustee as may be specified from time to time by a
Company 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 a Company Order or pursuant to such procedures and (d) if provided
for in such procedures, such Company Order may authorize authentication and
delivery pursuant to oral or electronic instructions from the Company or its
duly authorized agent or agents, which instructions, if oral, shall be promptly
confirmed in writing;

          (2)  any Board Resolution, Officer's Certificate and/or executed
Supplemental Indenture referred to in Section 2.01 and 2.03 by or pursuant to
which the forms and terms of the Securities and Coupons, if any, were
established;

          (3)  an Officer's Certificate setting forth the form or forms and
terms of the Securities and Coupons, if any, stating that the form or forms and
terms of the Securities and Coupons, if any, have been established pursuant to
Sections 2.01 and 2.03 and comply with this Indenture, and covering such other
matters as the Trustee may reasonably request; and

          (4)  at the option of the Company, 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 and Coupons, if any,
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, an Officer's Certificate or a Supplemental Indenture in
accordance with this Indenture, and when such other terms as are to be
established pursuant to procedures set forth in a Company Order shall have been
established, all such terms will have been duly authorized by the Company and
will have been established in conformity with the provisions of this Indenture;

               (c)  such Securities, when executed and issued by the Company and
authenticated by the Trustee in accordance with the provisions of this Indenture
and duly paid for by the purchasers thereof, and subject to any conditions
specified in such Opinion of Counsel, will constitute valid and binding
obligations of the Company, except as any rights thereunder may be limited by
the effect of bankruptcy, insolvency, reorganization, receivership,
conservatorship, arrangement, moratorium or other laws affecting or relating to
the rights of creditors generally; the rules governing the availability of
specific performance, injunctive relief or other equitable remedies and general
principles of equity, regardless of whether considered in a proceeding in equity
or at law; the effect of applicable court decisions invoking statutes or
principles of equity, which have held that certain covenants and provisions of
agreements are unenforceable where the breach of such covenants or provisions
imposes restrictions or burdens upon a borrower, and it cannot be demonstrated
that the enforcement of such restrictions or burdens is necessary for the
protection of the creditor, or which have held that the creditor's

                                       11
<PAGE>

enforcement of such covenants or provisions under the circumstances would have
violated the creditor's covenants of good faith and fair dealing implied under
California law; and the effect of California statutes and rules of law which
cannot be waived prospectively by a borrower, and such counsel need express no
opinion with regard to the enforceability of Section 7.06 or of a judgment
denominated in a currency other than United States Dollars; and

               (d)  the Company has complied with all applicable Federal laws
and requirements in respect of the execution and delivery of such Securities.

          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 Company 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 if the Trustee, being advised by
counsel, determines that such action may not lawfully be taken by the Company 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.

     SECTION 2.05.  Execution of Securities.  The Securities and each Coupon
                    -----------------------
appertaining thereto, if any, shall be executed manually or in facsimile, by any
two of the Chairman of the Board, Chief Executive Officer, the President, any
Vice President, the Secretary, any Assistant Secretary, the Chief Financial
officer, the Treasurer or any Assistant Treasurer of the Company under its
corporate seal (except in the case of Coupons), which may be affixed thereto or
printed, engraved or otherwise reproduced thereon, by facsimile or otherwise.
Only such Securities or Coupons, if any, as shall bear thereon a certificate of
authentication substantially in the form recited herein, executed by the Trustee
manually by an authorized officer, shall be entitled to the benefits of this
Indenture or be valid or obligatory for any purpose.  Such certificate of
authentication of the Trustee upon any Security or Coupon, if any, executed by
the Company shall be conclusive evidence that the Security or Coupon so
authenticated has been duly authenticated and delivered hereunder and that the
Holder is entitled to the benefits of this Indenture.  Typographical or other
errors or defects in the seal or facsimile signature on any Security or in the
text thereof shall not affect the validity or enforceability of such Security if
it has been duly authenticated and delivered by the Trustee.

     In case any officer of the Company who shall have signed any of the
Securities or Coupons, if any, (manually or in facsimile) shall cease to be such
officer before the Securities or Coupons so signed shall have been authenticated
and delivered by the Trustee, or disposed of by the Company, such Securities or
Coupons nevertheless may be authenticated and delivered or

                                       12
<PAGE>

disposed of as though the Person who signed such Securities or Coupons had not
ceased to be such officer of the Company. Also, any Security or Coupon may be
signed on behalf of the Company by such Persons as on the actual date of
execution of such Security or Coupon shall be the proper officers of the
Company, although at the date of the execution of this Indenture or on the
nominal date of such Security any such Person was not such officer.

     SECTION 2.06.  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. No Coupon shall be entitled to the
benefits of this Indenture or shall be valid and obligatory for any purpose
until the certificate of authentication on the Security to which such Coupon
appertains shall have been duly executed by the Trustee. The execution of such
certificate by the Trustee upon any Security executed by the Company 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 2.07.  Denominations; Payment of Interest on Securities.
                    ------------------------------------------------

     (a)  The Securities of each series may be issued as Registered Securities
or Unregistered Securities in denominations all as shall be specified as
contemplated by Section 2.03. In the absence of such provisions with respect to
the Registered Securities of any series, the Securities of such series (other
than any Registered Global Securities) shall be issued in denominations of
$1,000 (or [Euro] 1,000, as applicable) and any integral multiple thereof. If
denominations of Unregistered Securities of any series are not so established,
such Securities shall be issuable in denominations of $1,000 and $5,000 (or
[Euro] 1,000 and [Euro] 5,000). 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 Company executing the same may determine with the
approval of the Trustee, as evidenced by the execution and authentication
thereof.

     (b)  If the Securities of any series shall bear interest, each Security of
such series shall bear interest from the applicable date at the rate per annum
specified in the Officer's Certificate or Supplemental Indenture with respect to
such series of Securities. Unless otherwise specified in the Officer's
Certificate or Supplemental Indenture with respect to the Securities of any
series, interest on the Securities of such series shall be computed on the basis
of a 360-day year of twelve 30-day months. Such interest shall be payable on the
Interest Payment Dates specified in the Officer's Certificate or Supplemental
Indenture with respect to such series of Securities. The Person in whose name
any Security (or one or more Predecessor Securities) is registered at the close
of business on the applicable Record Date for the series of which such Security
is a part shall be entitled to receive the interest payable thereon on such
Interest Payment Date notwithstanding the cancellation of such Security upon any
transfer or exchange thereof subsequent to such Record Date and prior to such
Interest Payment Date unless such Security shall have been called for redemption
on a Redemption Date which is subsequent to such Record Date and prior to such
Interest Payment Date or unless the Company shall default in the payment of
interest due on such Interest Payment Date on any Security of such series.

     Any interest on any Security of any series which is payable, but is not
punctually paid or duly provided for, on any Interest Payment Date (herein
called "Defaulted Interest") shall

                                       13
<PAGE>

forthwith cease to be payable to the registered Holder on the relevant Record
Date solely by virtue of such Holder having been such Holder; and such Defaulted
Interest may be paid by the Company, at its election in each case, as provided
in clause (1) or (2) below:

     (1)  The Company may elect to make payment of any Defaulted Interest on the
Securities of any series to the Persons in whose names such Securities (or their
respective Predecessor Securities) are registered at the close of business on a
Special Record Date for the payment of such Defaulted Interest, which shall be
fixed in the following manner. The Company shall notify the Trustee in writing
of the amount of Defaulted Interest proposed to be paid on each Security and the
date of the proposed payment (which date shall be such as will enable the
Trustee to comply with the next sentence hereof), and at the same time the
Company shall deposit with the Trustee an amount of money equal to the aggregate
amount proposed to be paid in respect of such Defaulted Interest or shall make
arrangements satisfactory to the Trustee for such deposit prior to the date of
the proposed payment, such money when deposited to be held in trust for the
benefit of the Persons entitled to such Defaulted Interest as in this subsection
provided. Thereupon the Trustee shall fix a Special Record Date for the payment
of such Defaulted Interest which shall be not more than 15 nor less than 10 days
prior to the date of the proposed payment and not less than 10 days after the
receipt by the Trustee of the notice of the proposed payment. The Trustee shall
promptly notify the Company of such Special Record Date and, in the name and at
the expense of the Company, shall cause notice of the proposed payment of such
Defaulted Interest and the Special Record Date therefor to be mailed, first-
class postage prepaid, to each Holder of a Security of such series at such
Holder's address as it appears in the Register not less than 10 days prior to
such Special Record Date. Notice of the proposed payment of such Defaulted
Interest and the Special Record Date therefor having been mailed as aforesaid,
such Defaulted Interest shall be paid to the Persons in whose names the
Securities of such series are registered on such Special Record Date and shall
no longer be payable pursuant to the following subsection (2).

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

     Interest on Securities of any series that bear interest may be paid by
mailing a check to the address of the person entitled thereto as such address
shall appear in the Register.

     Subject to the foregoing provisions of this Section 2.07, each Security
delivered under this Indenture upon transfer of or in exchange for or in lieu of
any other Security shall carry all the rights to interest accrued and unpaid,
and to accrue, which were carried by such other Security and each such Security
shall bear interest from such date, such that neither gain nor loss in interest
shall result from such transfer, exchange or substitution.

     SECTION 2.08.  Registration, Transfer and Exchange of Securities.  Except
                    -------------------------------------------------
as specifically otherwise provided herein with respect to Registered Global
Securities, Securities of any series may be exchanged for a like aggregate
principal amount of Securities of the same series of other authorized
denominations. Securities to be exchanged shall be surrendered at the offices or
agencies to be maintained in accordance with the provisions of Section 4.03 and
the

                                       14
<PAGE>

Company shall execute the Security or Securities, and the Trustee shall
authenticate and deliver in exchange therefor the Security or Securities which
the Securityholder making the exchange shall be entitled to receive.

     The Company shall cause the Trustee to keep or cause to be kept, at one or
more of the offices or agencies to be maintained by the Trustee in accordance
with the provisions of Section 4.04 with respect to the Securities of each
series, the Register in which, subject to such reasonable regulations as it may
prescribe, the Company shall provide for the registration of the Registered
Securities of such series and the transfer of Registered Securities of such
series as in this Article provided. The Register shall be in written form or in
any other form capable of being converted into written form within a reasonable
time. At all reasonable times the Register shall be open for inspection by the
Trustee and any registrar of the Securities of such series other than the
Trustee. Upon due presentment for transfer of any Security of any series at the
offices or agencies of the Company to be maintained in accordance with Section
4.03 with respect to the Registered Securities of such series, the Company shall
execute a new Security and the Trustee shall authenticate and deliver in the
name of the transferee or transferees a new Security or Registered Securities of
the same series for a like aggregate principal amount of authorized
denominations. Notwithstanding any other provisions of this Section 2.08, unless
and until it is exchanged in whole or in part for Registered Securities in
definitive form, a Global Security representing all or a portion of the
Registered Securities of a series may not be transferred except as a whole by
the Depository for such series to a nominee of such Depository or by a nominee
of such Depository to such Depository or another nominee of such Depository or
by such Depository or any such nominee to a successor Depository for such series
or a nominee of such successor Depository.

     Unregistered Securities (except for any temporary global Unregistered
Securities) and Coupons (except for Coupons attached to any temporary global
Unregistered Securities) shall be transferable by delivery.

     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 and
tenor having authorized denominations and an equal aggregate principal amount,
upon surrender of such Registered Securities to be exchanged at the agency of
the Company that shall be maintained for such purpose in accordance with Section
4.03 and upon payment, if the Company shall so require, of the charges
hereinafter provided. If the Securities of any series are issued in both
registered and unregistered form, except as otherwise established pursuant to
Section 2.03, at the option of the Holder thereof, Unregistered Securities of
any series may be exchanged for Registered Securities of such series and tenor
having authorized denominations and an equal aggregate principal amount, upon
surrender of such Unregistered Securities to be exchanged at the agency of the
Company that shall be maintained for such purpose in accordance with Section
4.03, with, in the case of Unregistered Securities that have Coupons attached,
all unmatured Coupons and all matured Coupons in default thereto appertaining,
and upon payment, if the Company shall so require, of the charges hereinafter
provided. At the option of the Holder thereof, if Unregistered Securities of any
series, maturity date, interest rate and original issue date are issued in more
than one authorized denomination, except as otherwise established pursuant to
Section 2.03, such Unregistered Securities may be exchanged for Unregistered
Securities of such series and tenor

                                       15
<PAGE>

having authorized denominations and an equal aggregate principal amount, upon
surrender of such Unregistered Securities to be exchanged at the agency of the
Company that shall be maintained for such purpose in accordance with Section
4.03, with, in the case of Unregistered Securities that have Coupons attached,
all unmatured Coupons and all matured Coupons in default thereto appertaining,
and upon payment, if the Company shall so require, of the charges hereinafter
provided. Registered Securities of any series may not be exchanged for
Unregistered Securities of such series unless (1) otherwise specified pursuant
to Section 2.03 and (2) the Company has delivered to the Trustee an Opinion of
Counsel that (x) the Company has received from 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 the inclusion of terms
permitting Registered Securities to be exchanged for Unregistered Securities
would result in no United States federal income tax effect adverse to the
Company or to any Holder. Whenever any Securities are so surrendered for
exchange, the Company shall execute, and the Trustee shall authenticate and
deliver, the Securities which the Holder making the exchange is entitled to
receive. All Securities and Coupons, if any, 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 Company.

     All Registered Securities of any series presented or surrendered for
exchange, transfer, redemption, conversion or payment shall, if so required by
the Company or any registrar of the Securities of such series, be accompanied by
a written instrument or instruments of transfer, in form  satisfactory to the
Company and such registrar, duly executed by the registered Holder or by such
Person's attorney duly authorized in writing.

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

     The Company shall not be required to exchange or transfer (a) any
Securities of any series during a period beginning at the opening of business 15
days before the day of the first publication or the mailing (if there is no
publication) of a notice of redemption of Securities of such series and ending
at the close of business on the day of such publication or mailing or (b) any
Securities called or selected for redemption in whole or in part, except, in the
case of Securities called for redemption in part, the portion thereof not so
called for redemption in whole or in part or during a period beginning at the
opening of business on any Record Date for such series and ending at the close
of business on the relevant Interest Payment Date therefor.

     SECTION 2.09.  Mutilated, Defaced, Destroyed, Lost and Stolen Securities.
                    ---------------------------------------------------------
In case any temporary or definitive Security or any Coupon appertaining to any
Security shall be mutilated, defaced, destroyed, lost or stolen, the Company in
its discretion may execute and, upon the written request of any officer of the
Company, the Trustee shall authenticate and delivery, 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 with Coupons
corresponding to the Coupons appertaining to the Securities so mutilated,
defaced, destroyed, lost or stolen, or in exchange or substitution for the
Security to which such mutilated, defaced, destroyed,

                                       16
<PAGE>

lost or stolen Coupon appertained, with Coupons appertaining thereto
corresponding to the Coupons so mutilated, defaced, destroyed, lost or stolen.
In every case the applicant for a substitute Security or Coupon shall furnish to
the Company and to the Trustee and any agent of the Company 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 or Coupon and of the ownership thereof, and in the case of mutilation
or defacement shall surrender the Security and related Coupons to the Trustee or
such agent.

     Upon the issuance of any substitute Security or Coupon, the Company may
require the payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in relation thereto and any other expenses (including
the fees and expenses of the Trustee) or its agent connected therewith.  In case
any Security or Coupon 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 Company may instead of issuing a substitute Security, pay or
authorize the payment of the same or the relevant Coupon (without surrender
thereof except in the case of a mutilated or defaced Security or Coupon), if the
applicant for such payment shall furnish to the Company and to the Trustee and
any agent of the Company 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 Company and
to the Trustee and any agent of the Company or the Trustee evidence to their
satisfaction of the destruction, loss or theft of such Security or Coupons and
of the ownership thereof.

     Every substitute Security or Coupon of any series issued pursuant to the
provisions of this Section by virtue of the fact that any such Security or
Coupon is destroyed, lost or stolen shall constitute an additional contractual
obligation of the Company, whether or not the destroyed, lost or stolen Security
or Coupon 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 or Coupons of such series duly authenticated and delivered hereunder.
All Securities and Coupons 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 Coupons and shall preclude any and all other
rights or remedies notwithstanding any law or statue 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 and Destruction of Surrendered Securities.  All
                    ------------------------------------------------------
Securities and Coupons surrendered for payment, redemption, transfer, conversion
or exchange, or for credit against any payment in respect of a sinking or
analogous fund, if any, shall, if surrendered to the Company, the Trustee or any
agent of the Company or of the Trustee, be delivered to the Trustee, and the
same, together with Securities surrendered to the Trustee for cancellation,
shall be canceled by it and thereafter disposed of by it as directed by the
Company, and no Securities or Coupons shall be issued in lieu thereof except as
expressly permitted by any of the provisions of this Indenture.  The Trustee
shall destroy canceled Securities and Coupons and deliver a certificate of
destruction thereof to the Company unless by an Officer's Certificate of the
Company, the Company shall direct that canceled Securities be returned to it. If
the Company shall purchase or otherwise acquire any of the Securities and
Coupons, however, such purchase or acquisition shall not operate as a payment,
redemption or satisfaction of the indebtedness

                                       17
<PAGE>

represented by such Securities or Coupons unless and until the Company, at its
option shall deliver or surrender the same to the Trustee for cancellation.

     SECTION 2.11.  Temporary Securities.  Pending the preparation of definitive
                    --------------------
Securities of any series, the Company may execute and the Trustee shall
authenticate and deliver temporary Securities of such series which are printed,
lithographed, typewritten or otherwise produced, in each case satisfactory to
the Trustee.  Temporary Securities of any series shall be issuable as Registered
Securities without coupons, or as Unregistered Securities with or without
coupons attached thereto of any authorized denomination, and substantially in
the form of the definitive Securities of such series but with such appropriate
omissions, insertions, substitutions and other variations as the officers
executing such Securities may determine, as evidenced by their execution of such
Securities.  Every such temporary Security shall be authenticated by the Trustee
upon the same conditions and in substantially the same manner, and with the same
effect, as the definitive Securities.  If temporary Securities are issued, the
Company will cause definitive Securities to be prepared without unreasonable
delay.  After the preparation of definitive Securities, the temporary Securities
of such series shall be exchangeable for definitive Securities upon surrender of
the temporary Securities without charge to the Holder at the offices or agencies
to be maintained by the Trustee as provided in Section 4.03 with respect to the
Securities of such series and in the case of Unregistered Securities, at any
agency maintained by the Company for such purpose as specified pursuant to
Section 2.03.  Upon surrender for cancellation of any one or more temporary
Securities the Company shall execute and the Trustee shall authenticate and
deliver in exchange for such temporary Securities an equal aggregate principal
amount of definitive Securities of such series and in the case of Unregistered
Securities, having attached thereto any appropriate Coupons.  Until so
exchanged, the temporary Securities of any series shall in all respects be
entitled to the benefits of this Indenture and interest thereon, when and as
payable, shall be paid to the registered owners thereof.  The provisions of this
Section are subject to any restrictions or limitations on the issue and delivery
of temporary Unregistered Securities of any series that may be established
pursuant to Section 2.03 (including any provision that Unregistered Securities
of such series initially be issued in the form of a single global Unregistered
Security to be delivered to a depositary or agency located outside the United
States and the procedures pursuant to which definitive or global Unregistered
Securities of such series would be issued in exchange for such temporary global
Unregistered Security).

     SECTION 2.12.  Securities in Global Form; Depositories. (a) Each Registered
                   ----------------------------------------
Global Security shall:  (i) represent and be denominated in an aggregate amount
equal to the aggregate principal amount of the Securities of the series to be
represented by such Registered Global Security, (ii) be registered in the name
of either the Depository for such Registered Global Security or the nominee of
such Depository, (iii) be delivered by the Trustee to such Depository or
pursuant to such Depository's written instruction and (iv) bear a legend
substantially to the following effect:  "Unless and until it is exchanged in
whole or in part for Securities in definitive form, this Registered Global
Security may not be transferred except as a whole by the Depository to a nominee
of the Depository or by a nominee of the Depository to the Depository or another
nominee of the Depository or by the Depository or any nominee to a successor
Depository or a nominee of any successor Depository."  The notation of the
record owner's interest in such Registered Global Security upon the original
issuance thereof shall be deemed to be delivery in connection with the original
issuance of each beneficial owner's interest in such Registered Global Security.
Without limiting the foregoing, the Company and the Trustee shall have no

                                       18
<PAGE>

responsibility, obligation or liability with respect to: (x) the maintenance,
review or accuracy of the records of the Depository or of any of its
participating organizations with respect to any ownership interest in or
payments with respect to such Registered Global Security, (y) any communication
with or delivery of any notice (including notices of redemption) with respect to
the series of Securities represented by the Registered Global Security to any
Person having any ownership interest in such Registered Global Security or to
any of the Depository's participating organizations or (z) any payment made on
account of any beneficial ownership interest in such Registered Global Security.

     (b) If any Security of a series is issuable in the form of a Registered
Global Security or Securities, each such Registered Global Security may provide
that it shall represent the aggregate amount of Outstanding Securities of such
series from time to time endorsed thereon and may also provide that the
aggregate amount of Outstanding Securities of such series represented thereby
may from time to time be reduced to reflect exchanges.  Any endorsement of a
Registered Global Security to reflect the amount of Outstanding Securities of a
series represented thereby shall be made by the Trustee and in such manner as
shall be specified on such Registered Global Security.  Any instructions by the
Company with respect to a Registered Global Security, after its initial
issuance, shall be in writing but need not comply with Section 13.03 of this
Indenture.

     (c) Each Depository designated pursuant to the provisions of Section 2.03
of this Indenture for a Registered Global Security must, at the time of its
designation and at all times while it serves as a depositary, be a clearing
agency registered under the Exchange Act, and any other applicable statute or
regulation.  If at any time the Depository for the Securities of a series
notifies the Company that it is unwilling or unable to continue as Depository
for the Securities of such series or if at any time the Depository for the
Securities of such series shall no longer be eligible under this Section 2.12,
the Company shall appoint a successor Depository with respect to the Securities
of such series.  If a successor Depository for the Securities of such series is
not appointed by the Company within 90 days after the Company receives such
notice or learns of such ineligibility, the Company shall execute and the
Company shall direct the Trustee to authenticate and deliver definitive
Securities of such series in authorized denominations in exchange for the
Registered Global Security or Securities.  Upon receipt of such direction, the
Trustee shall thereupon authenticate and deliver the definitive Securities of
such series in the same aggregate principal amount as the Registered Global
Security or Securities representing such series in exchange for such Registered
Global Security or Securities, in accordance with the provisions of subsection
(e) of this Section 2.12, without any further corporate action by the Company.

     (d) The Company 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 such Registered
Global Security or Securities.  In such event, the Company will execute and upon
receipt of a written order from the Company, the Trustee shall thereupon
authenticate and deliver Securities of such series in definitive form and in
authorized denominations in an aggregate principal amount equal to the principal
amount of the Registered Global Security or Securities representing such series
in exchange for such Registered Global Security or Securities, in accordance
with the provisions of subsection (e) of this Section 2.12 without any further
corporate action by the Company.

                                       19
<PAGE>

     (e) Upon any exchange hereunder of the Registered Global Security or
Securities for Securities in definitive form, such Registered Global Security or
Securities shall be canceled by the Trustee.  Registered Securities issued
hereunder in exchange for the Registered Global Security or Securities shall be
registered in such names and in such authorized denominations as the Depository
for such Registered Global Security, pursuant to instructions from its direct or
indirect participants or otherwise, shall instruct the Trustee.  The Trustee
shall deliver such definitive Securities in exchange for the Registered Global
Security or Securities to the persons in whose name such definitive Securities
have been registered in accordance with the directions of the Depository.

     (f) Any time the Registered Securities of any series are not in the form of
Registered Global Securities pursuant to the preceding two paragraphs, the
Company agrees to supply the Trustee with a reasonable supply of certified
Registered Securities without the legend required by this Section 2.12 and the
Trustee agrees to hold such Registered Securities in safekeeping until
authenticated and delivered pursuant to the terms of this Indenture.

     If established by the Company pursuant to Section 2.03 with respect to any
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 and tenor in definitive registered form on
such terms as are acceptable to the Company and such Depositary.  Thereupon, the
Company shall execute, and the Trustee shall authenticate and deliver, without
service charge,

          (i)    to the Person specified by such Depositary new Registered
     Securities of the same series and tenor, 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.

     Registered Securities issued in exchange for a Registered Global Security
pursuant to this Section 2.12 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 Company 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 Company, evidencing the same debt, and entitled to the
same benefits under this Indenture, as the Securities surrendered upon such
transfer or exchange.

     Notwithstanding anything herein or in the forms or terms of any Securities
to the contrary, none of the Company, the Trustee or any agent of the Company or
the Trustee shall be required to exchange any Unregistered Security for a
Registered Security if such exchange would result in adverse Federal income tax
consequences to the Company (such as, for example,

                                       20
<PAGE>

the inability of the Company to deduct from its income, as computed for Federal
income tax purposes, the interest payable on the Unregistered Securities) under
then applicable United States Federal income tax laws. The Trustee and any such
agent shall be entitled to rely on an Officers' Certificate or an Opinion of
Counsel in determining such result.

     SECTION 2.13.  CUSIP Numbers.  The Company in issuing the Securities may
                    -------------
use "CUSIP" and "CINS" numbers (if then generally in use), and the Trustee shall
use CUSIP numbers or CINS numbers, as the case may be, in notices of redemption
or exchange as a convenience to Holders and no representation shall be made as
to the correctness of such numbers either as printed on the Securities or as
contained in any notice of redemption or exchange.

     SECTION 2.14.  Series May Include Tranches.  A series of Securities may
                    ---------------------------
include one or more tranches (each a "tranche") of Securities, including
Securities issued in a Periodic Offering.  The Securities of different tranches
may have one or more different terms, including authentication dates and public
offering prices, but all the Securities within each such tranche shall have
identical terms, including authentication date and public offering price.
Notwithstanding any other provision of this Indenture, with respect to Sections
2.05 (other than the fourth paragraph thereof) through 2.12, 3.01 through 3.05,
4.03, 6.01 through 6.12, 10.02 and 11.01 through 11.05, if any series of
Securities includes more than one tranche, all provisions of such sections
applicable to any series of Securities shall be deemed equally applicable to
each tranche of any series of Securities in the same manner as though originally
designated a series unless otherwise provided with respect to such series or
tranche pursuant to Section 2.03.  In particular, and without limiting the scope
of the next preceding sentence, any of the provisions of such sections which
provide for or permit action to be taken with respect to a series of Securities
shall also be deemed to provide for and permit such action to be taken instead
only with respect to Securities of one or more tranches within that series (and
such provisions shall be deemed satisfied thereby), even if no comparable action
is taken with respect to Securities in the remaining tranches of that series.

                                 ARTICLE THREE

                  REDEMPTION OF SECURITIES AND SINKING FUNDS

     SECTION 3.01.  Applicability of Article.  The provisions of this Article
                    ------------------------
shall be applicable to the Securities of any series which are redeemable before
their Stated Maturity or to any sinking fund for the retirement of Securities of
a series except as otherwise specified as contemplated by Section 2.03 for
Securities of such series.

     SECTION 3.02.  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 Company 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 Register.  Notice of redemption to the Holders of Unregistered Securities to
be redeemed as a whole or in part, who have filed their names and addresses with
the Trustee pursuant to Section 313(c)(2) of the Trust Indenture Act shall be
given by mailing notice of such redemption, by first class mail, postage
prepaid, at least 30 days and not more than 60 prior to the date fixed for

                                       21
<PAGE>

redemption, to such Holders at such addresses as were so furnished to the
Trustee (and, in the case of any such notice given by the Company, the Trustee
shall make such information available to the Company for such purpose).  Notice
of redemption to all other Holders of Unregistered Securities shall be published
in an Authorized Newspaper in the Borough of Manhattan, The City of New York and
in an Authorized Newspaper in London (and, if required by Section 4.09, in an
Authorized Newspaper in Luxembourg), in each case, once in each of three
successive calendar weeks, the first publication to be not less than 30 nor more
than 60 days prior to the date fixed for redemption.  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 Holder shall specify the principal
amount of each Security of such series held by such 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
and, in the case of Securities with Coupons attached thereto, of all Coupons
appertaining thereto maturing after the date fixed for redemption, 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
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 Company shall be given by the Company or, at the Company's
request, by the Trustee in the name and at the expense of the Company.

     On or before the redemption date specified in the notice of redemption
given as provided in this Section, the Company will deposit with the Trustee or
with one or more Paying Agents (or, if the Company is acting as its own Paying
Agent, set aside, segregate and holder in trust as provided in Section 4.05) 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 Company
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 Company prior to the
expiration of any restriction on such redemption, the Company 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 deem 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 Company in writing of the Securities of such series
selected for

                                       22
<PAGE>

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 3.03.  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 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 Company 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 the unmatured Coupons, if any, appertaining thereto shall be void,
and, except as provided in Sections 7.05 and 11.04, 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,
together with all Coupons, if any, appertaining thereto maturing after the date
fixed for redemption, said Securities or the specified portions thereof shall be
paid and redeemed by the Company 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 in the case of Securities with Coupons attached thereto, to the
Holders of the Coupons for such interest upon surrender thereof, and in the case
of Registered Securities, to the Holder of such Registered Securities registered
as such on the relevant record date, subject to the terms and provisions of
Section 2.03 and 2.07 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.

     If any Security with Coupons attached thereto is surrendered for redemption
and is not accompanied by all appurtenant Coupons maturing after the date fixed
for redemption, the surrender of such missing Coupon or Coupons may be waived by
the Company and the Trustee, if there be furnished to each of them such security
or indemnity as they may require to save each of them harmless.

     Upon presentation of any Security redeemed in part only, the Company shall
execute and the Trustee shall authenticate and deliver to or on the order of the
Holder thereof, at the expense of the Company, 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 3.04.  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

                                       23
<PAGE>

Company 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 Company.

     SECTION 3.05.  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 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 Company 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 Company or receive credit for Securities of such series (not
previously so credited) theretofore purchased or otherwise acquired (except as
aforesaid) by the Company 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 Company
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 60/th/ day next preceding each sinking fund payment date
for any series, the Company will deliver to the Trustee an Officer's Certificate
(which need not contain the statements required by Section 13.03) (a) specifying
the portion of the mandatory sinking fund payment to be satisfied by payment of
cash and the portion to be s atisfied 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 Company 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 Company 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 Company to be entitled to credit therefor as aforesaid which have
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 Company 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 Company, on or before any
such 60/th/ 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 Company (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
Company will make no optional sinking fund payment with respect to such series
as provided in this Section.

                                       24
<PAGE>

     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 the equivalent thereof in any Foreign Currency or ECU) or a lesser sum in
United States Dollars (or the equivalent thereof in any Foreign Currency or ECU)
if the Company 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 the equivalent thereof in any
Foreign Currency or ECU) or less and the Company makes no such request then it
shall be carried over until a sum in excess of $50,000 (or the equivalent
thereof in any Foreign Currency or ECU) is available.  The Trustee shall select,
in the manner provided in Section 3.02, 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
Company) inform the Company 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 Company 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 Company.  The Trustee, in the name
and at the expense of the Company (or the Company, 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 3.02 (and
with the effect provided in Section 3.03) for the redemption of Securities of
such series in part at the option of the Company.  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 its Stated
Maturity.

     On or before each sinking fund payment date, the Company 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 Company 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 5 and held for the payment of all such Securities.  In case such

                                       25
<PAGE>

Event of Default shall have been waived as provided in Section 6.09 or the
default cured on or before the sixtieth 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.

                                 ARTICLE FOUR

                      PARTICULAR COVENANTS OF THE COMPANY

     SECTION 4.01.  Payment of Principal of and Interest on Securities.  The
                    --------------------------------------------------
Company covenants that it will duly and punctually pay or cause to be paid the
principal of and any interest and premium on each of the Securities in
accordance with the terms of the Securities and in the Coupons, if any,
appertaining thereto and this Indenture.  Except with respect to any Registered
Global Securities, if the Securities of any series bear interest, each
installment of interest on the Securities of such series may, at the option of
the Company, be paid by mailing a check or checks for such interest payable to
the Person entitled thereto pursuant to Section 2.07 to the address of such
Person as it appears on the Register of such series on the applicable Record
Date for such interest payment.  The interest on Securities with Coupons
attached (together with any additional amounts payable pursuant to the terms of
such Securities) shall be payable only upon presentation and surrender of the
several Coupons for such interest installments as are evidenced thereby as they
severally mature.  If any temporary Unregistered Security provides that interest
thereon may be paid while such Security is in temporary form, the interest on
any such temporary Unregistered Security (together with any additional amounts
payable pursuant to the terms of such Security) shall be paid, as to the
installments of interest evidenced by Coupons attached thereto, if any, only
upon presentation and surrender thereof, and, as to the other installments of
interest, if any, only upon presentation of such Securities for notation thereon
of the payment of such interest, in each case subject to any restrictions that
may be established pursuant to Section 2.03.  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 Company, 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 Register of
the Company.

     SECTION 4.02.  Corporate Existence of the Company; Consolidation, Merger,
                    ----------------------------------------------------------
Sale or Transfer. The Company covenants that so long as any of the Securities
----------------
are Outstanding, it will maintain its existence, will not dissolve, sell or
otherwise dispose of all or substantially all of its assets and will not
consolidate with or merge into another entity or permit one or more other
entities to consolidate with or merge into it; provided that the Company may,
without violating the covenants in this Section 4.02 contained, consolidate with
or merge into another entity or permit one or more other entities to consolidate
with or merge into it, or sell or otherwise transfer to another entity all or
substantially all of its assets as an entirety and thereafter dissolve, if the
surviving, resulting or transferee entity, as the case may be, (i) shall be
organized and existing under the laws of one of the States of the United States
of America, (ii) assumes, if such entity is not the Company, all of the
obligations of the Company hereunder and (iii) is not, after such transaction,

     SECTION 4.03.  Maintenance of Offices or Agencies for Transfer,
                    ------------------------------------------------
Registration, Exchange and Payment of Securities.  So long as any of the
------------------------------------------------
Securities shall remain Outstanding,

                                       26
<PAGE>

the Company covenants that it will cause the Trustee to maintain an office or
agency in either The City of [New York, State of New York], or the City and
County of San Francisco, State of California, where the Securities may be
presented for registration, exchange and transfer as in this Indenture provided,
and where notices and demands to or upon the Trustee in respect of the
Securities or of this Indenture may be served, and where the Securities may be
presented for payment. In case the Trustee shall fail to maintain any such
office or agency, presentations and demands may be made and notices may be
served at the principal office of the Company.

     The Company will maintain one or more agencies in a city or cities located
outside the United States (including any city in which such an agency is
required to be maintained under the rules of any stock exchange on which the
Securities of any series are listed) where the Unregistered Securities, if any,
of each series and Coupons, if any, appertaining thereto may be presented for
payment.  No payment on any Unregistered Security or Coupon will be made upon
presentation of such Unregistered Security or Coupon at an agency of the Company
within the United States nor will any payment be made by transfer to an account
in, or by mail to an address in, the United States unless, pursuant to
applicable United States laws and regulations then in effect, such payment can
be made without adverse tax consequences to the Company.  Notwithstanding the
foregoing, if full payment in United States Dollars at each agency maintained by
the Company outside the United States for payment on such Unregistered
Securities or Coupons appertaining thereto is illegal or effectively precluded
by exchange controls or other similar restrictions, payments in United States
Dollars of Unregistered Securities of any series and coupons appertaining
thereto which are payable in United States Dollars may be made at an agency of
the Company maintained in the City of New York.

     The Company will maintain in the Borough of Manhattan, The City of New
York, an office or agency where notices and demands to or upon the Company in
respect of the Securities of any series, the Coupons appertaining thereto or
this Indenture may be served.

     The Company 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
Company shall fail to maintain any agency required by this Section to be located
in the Borough of Manhattan, The City of New York or the City and County of San
Francisco, 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 Principal Office of the Trustee.

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

     SECTION 4.04.  Appointment to Fill a Vacancy in the Office of Trustee. The
                    ------------------------------------------------------
Company, whenever necessary to avoid or fill a vacancy in the office of Trustee,
covenants that it will

                                       27
<PAGE>

appoint, in the manner provided in Section 7.10, a Trustee, so that there shall
at all times be a Trustee with respect to the Outstanding Securities.

     SECTION 4.05.  Duties of Paying Agent.  (a)  If the Company shall appoint a
                    ----------------------
Paying Agent other than the Trustee with respect to 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 4.05 and Section 11.04,

          (1) that it will hold all sums held by it as such agent for the
payment of the principal of or interest, if any, on the Securities of such
series (whether such sums have been paid to it by the Company or by any other
obligor on the Securities of such series) in trust for the benefit of the
Holders of the Securities entitled to such principal or interest and will notify
the Trustee of the receipt of sums to be so held,

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

          (3) that it will at any time during the continuance of any Event of
Default, upon the written request of the Trustee, deliver to the Trustee all
sums so held in trust by it.

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

     (c) If the Company 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 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 or the
Coupons appertaining thereto a sum sufficient to pay such principal or interest
so becoming due.  The Company will promptly notify the Trustee of any failure to
take such action.

     (d) Anything in this Section 4.05 to the contrary notwithstanding, the
Company may, at any time, for the purpose of obtaining a satisfaction and
discharge of this Indenture 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 such series by it, or any Paying Agent
hereunder, as required by this Section 4.05, and such sums are to be held by the
Trustee upon the trust herein contained.

     SECTION 4.06.  Notice of Default.  The Company covenants that, as soon as
                    -----------------
is practicable, the Company will furnish the Trustee notice of any event which
is an Event of Default or which with the giving of notice or the passage of time
or both would constitute an Event of Default which has occurred and is
continuing on the date of such notice, which notice shall set forth the nature
of such event and the action which the Company proposes to take with respect
thereto.

                                       28

     SECTION 4.07.  Maintenance of Properties.  The Company will cause all
                    -------------------------
properties used in or useful in the conduct of its business to be maintained and
kept in good condition, repair, and working order and supplied with all
necessary equipment and will cause to be made all necessary repairs, renewals,
replacements, betterments and improvements thereof, all as in the judgment of
the Company may be necessary, so that the business carried on in connection
therewith may be properly and advantageously conducted at all time except to the
extent that the Company may be prevented from so doing by circumstances beyond
its control; provided, that nothing in this Section shall prevent the Company
from discontinuing the operation or maintenance of any of such properties, or
disposing of any of them, if such discontinuance or disposal is, in the judgment
of the Company desirable in the conduct of the business of the Company and not
disadvantageous in any material respect to the Securityholders.

     SECTION 4.08.  Payment of Taxes and Other Claims.  The Company 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 Company or upon the income, profits or property of the Company;
and (b) all lawful claims for labor, materials, and supplies, which, if unpaid,
might by law become a lien upon the property of the Company; provided, that the
Company 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; and
provided further that the Company shall not be required to cause to be paid or
discharged any such tax, assessment, charge or claim if the Company shall
determine that such payment is not advantageous to the conduct of the business
of the Company taken as a whole and that the failure so to pay or discharge is
not disadvantageous in any material respect to the Securityholders.

     SECTION 4.09.  Luxembourg Publications.  In the event of the publication of
                    -----------------------
any notice pursuant to Section 3.02, 6.10, 7.10(a), 7.11 and 10.02, the party
making such publication in the Borough of Manhattan, The City of New York and
London shall also, to the extent that notice is required to be given to Holders
of Securities of any series by applicable Luxembourg law or stock exchange
regulation, as evidenced by an Officer's Certificate delivered to such party,

                      SECURITYHOLDERS' LISTS AND REPORTS
                        BY THE COMPANY AND THE TRUSTEE

     SECTION 5.01.  Company to Furnish Trustee Information as to the Names and
                    ----------------------------------------------------------
Addresses of Securityholders.  The Company will furnish or cause to be furnished
----------------------------
to the Trustee, not less than 45 days nor more than 60 days after each date
(month and day) specified as an Interest Payment Date for the Securities of the
first series issued under this Indenture (whether or not any Securities of that
series are then Outstanding), but in no event less frequently than semiannually,
and at such other times as the Trustee may request in writing, within 30 days
after receipt by the Company of any such request, a list in such form as the
Trustee may reasonably require containing all the information in the possession
or control of the Company, or any of its Paying Agents other than the Trustee,
as to the names and addresses of the Holders of Securities, obtained since the
date as of which the next previous list, if any, was furnished, excluding from
any such list the names and addresses received by the Trustee in its capacity as
registrar (if so

                                       29
<PAGE>

acting). Any such list may be dated as of a date not more than 15 days prior to
the time such information is furnished and need not include information received
after such date.

     SECTION 5.02.  Preservation of Information; Communication to
                    ---------------------------------------------
Securityholders.
---------------

     (a)  The Trustee shall preserve, in as current a form as is reasonably
practicable, the names and addresses of the Holders of Securities of each series
(1) contained in the most recent list furnished to it as provided in Section
5.01, (2) received by the Trustee in the capacity of Paying Agent or registrar
(if so acting) and (3) filed with the Trustee within the two preceding years as
provided for in Section 5.04(c).  The Trustee may destroy any list furnished to
it as provided in Section 5.01 upon receipt of a new list so furnished.

     (b) If three or more Holders of Securities (hereinafter referred to as
"applicants") apply in writing to the Trustee, and furnish to the Trustee
reasonable proof that each such applicant has owned a Security for a period of
at least six months preceding the date of such application, and such application
states that the applicants desire to communicate with other Holders of
Securities of any series or with Holders of all Securities with respect to their
rights under this Indenture or under such Securities, and is accompanied by a
copy of the form of proxy or other communication which such applicants propose
to transmit, then the Trustee shall, within five Business Days after the receipt
of such application, at its election, either:

          (1) afford such applicants access to the information preserved at the
time by the Trustee in accordance with the provisions of subsection (a) of this
Section 5.02; or

          (2) inform such applicants as to the approximate number of Holders of
Securities of such series or all Securities, as the case may be, whose names and
addresses appear in the information preserved at the time by the Trustee in
accordance with the provisions of subsection (a) of this Section 5.02, and as to
the approximate cost of mailing to such Securityholders the form of proxy or
other communications, if any, specified in such application.

     If the Trustee shall elect not to afford such applicants access to such
information, the Trustee shall, upon the written request of such applicants,
mail to each of the Holders of Securities of such series, or all Securities, as
the case may be, whose name and address appear in the information preserved at
the time by the Trustee in accordance with the provisions of subsection (a) of
this Section 5.02, a copy of the form of proxy or other communication which is
specified in such request, with reasonable promptness after a tender to the
Trustee of the material to be mailed and of payment, or provision for the
payment, of the reasonable expenses of mailing, unless within five days after
such tender, the Trustee shall mail to such applicants and file with the
Commission, together with a copy of the material to be mailed, a written
statement to the effect that, in the opinion of the Trustee, such mailing would
be contrary to the best interests of the Holders of Securities of such series or
all Securities, as the case may be, or would be in violation of applicable law.
Such written statement shall specify the basis of such opinion.  If the
Commission, after opportunity for a hearing upon the objections specified in the
written statement so filed, shall enter an order refusing to sustain any of such
objections or if, after the entry of an order sustaining one or more of such
objections, the Commission shall find, after notice and opportunity for hearing,
that all the objections so sustained have been met and shall enter an order so
declaring, the Trustee shall mail copies of such material to all such
Securityholders with reasonable promptness after the entry of such order and the
renewal of such

                                       30
<PAGE>

tender; otherwise the Trustee shall be relieved of any obligation or duty to
such applicants respecting their application.

     (c) Each and every Holder of the Securities, by receiving and holding the
same, agrees with the Company and the Trustee that neither the Company nor the
Trustee nor any Paying Agent nor any registrar shall be held accountable by
reason of the disclosure of any such information as to the names and addresses
of the Holders of Securities in accordance with the provisions of subsection (b)
of this Section 5.02, regardless of the source from which such information was
derived, and that the Trustee shall not be held accountable by reason of mailing
any material pursuant to a request made under said subsection (b).

     SECTION 5.03.  Reports by Company.  (a)  The Company covenants and agrees
                    ------------------

the foregoing as the Commission may from time to time by rules and regulations
prescribe) which the Company may be required to file with the Commission
pursuant to Section 13 or Section 15(d) of the Exchange Act; or, if the Company
is not required to file information, documents or reports pursuant to either of
such sections, then to file with the Trustee and the Commission, in accordance
with rules and regulations prescribed from time to time by the Commission, such

Commission, in accordance with the rules and regulations prescribed from time to
time by the Commission, such additional information, documents and reports with
respect to compliance by the Company with the conditions and covenants provided
for in this Indenture as may be required from time to time by such rules and
regulations.

     (c) The Company covenants and agrees to transmit to the Holders of
Securities within 30 days after the filing thereof with the Trustee, in the
manner and to the extent provided in subsection (c) of Section 5.04 with respect
to reports pursuant to subsection (a) of said Section 5.04, such summaries of
any information, documents and reports required to be filed by the Company

accounting officer as to his or her knowledge of the Company's compliance with
all conditions and covenants of this Indenture (which compliance shall be

provided in this Indenture). Such certificates need not comply with Section
13.03 of this Indenture.

that of the Securities of any series, on any property or funds held or collected

to state such advances if such advances so remaining unpaid aggregate not more
than one-half of one percent of the principal amount of the Securities of such
series Outstanding on the date of such report;

          (4) the amount, interest rate and maturity date of all other
indebtedness owing by the Company (or by any other obligor on the Securities) to

     (a) default in the payment of any installment of interest on any Security
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 however, that an

                                       33
<PAGE>

voting as one class) at the time Outstanding under this Indenture a written
notice specifying such failure and stating that such is a "Notice of Default"
hereunder; or

     (e) the entry by a court having jurisdiction in the premises of a decree or
order for relief in respect of the Company in an involuntary case under any

     If an Event of Default described in clause (a), (b) or (c) shall have
occurred and be continuing with respect to any one or more series of Outstanding
Securities, then and in each and every such case, unless the principal amount of
all the Securities of each series as to which there is an Event of Default shall
have already become due and payable, either the Trustee or the Holders of not
less than 25% in principal amount of the Securities of such series then
Outstanding hereunder (each such series voting as a separate class) by notice in
writing to the Company (and to the Trustee if given by Securityholders) may
declare the principal amount (or, if the Securities of any such series are

notwithstanding.

     Except as otherwise provided in the terms of any series of Securities
pursuant to Section 2.03, if an Event of Default described in clause (d) or (g)

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

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

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, however, are subject to the condition that if, at
any time after the principal amount (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 one or more 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 moneys due shall have been
obtained or entered as hereinafter provided, the Company shall pay or shall
deposit with the Trustee a sum sufficient to pay all matured installments of
interest upon all the Securities of such series (or upon all the Securities, as
the case may be) and the principal of any and all Securities of such series (or
of any and all the Securities, as the case may be) which shall have become due
otherwise than by declaration (with interest on overdue installments of interest
to the extent permitted by law and on such principal at the rate or rates of
interest borne by, or prescribed therefor in the Securities of such series to
the date of such payment or deposit) and 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 the amounts payable to the Trustee under Section
7.06 and any and all defaults under the Indenture with respect to Securities of
such series (or all Securities, as the case may be), other than the non- payment
of principal of and any accrued interest on Securities of such series (or any
Securities, as the case may be) which shall have become due by declaration shall
have been cured, remedied or waived as provided in Section 6.09 -- then and in
every such case the Holders of a majority in principal amount of the Securities
of such series (or of all the Securities, as the case may be) then Outstanding
(such series or all series voting as one class if more than one series are so
entitled) by written notice to the Company and to the Trustee, may rescind and
annul such declaration and its consequences; but no such 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 Issue Discount Securities shall be

                                       35
<PAGE>

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.

     In case the Trustee shall have proceeded to enforce any right under this
Indenture and such proceedings shall have been discontinued or abandoned because
of such rescission or annulment or for any other reason or shall have been
determined adversely to the Trustee, then and in every such case the Company,
the Trustee and the Holders of the Securities of such series (or of all the
Securities, as the case may be) shall be restored respectively to their former
positions and rights hereunder, and all rights, remedies and powers of the
Company and the Trustee and the Holders of the Securities of such series (or of
all the Securities, as the case may be) shall continue as though no such
proceedings had been taken.

     SECTION 6.02.  Covenant of Company to Pay to Trustee Whole Amount Due on
                    ---------------------------------------------------------
Securities on Default in Payment of Interest or Principal.  The Company
---------------------------------------------------------
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 as and when the same shall
become due and payable and which payment has not been extended in accordance
with the provisions of  a Supplemental Indenture, 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 and which payment has not been extended in accordance
with the provisions of  a Supplemental Indenture, whether at the Stated Maturity
of such series or by any call for redemption or by declaration of acceleration
or otherwise; or

          (c) in case default shall be made in the satisfaction of any sinking
fund obligation when and as such obligation becomes due and payable and which
payment has not been extended in accordance with the provisions of a
Supplemental Indenture, upon demand of the Trustee, the Company 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 such Securities
of such series and such Coupons, for principal (and any premium) and interest
and for any overdue sinking fund payment together with interest upon the overdue
principal and installments of interest (to the extent permitted by law) at the
rate or rates of interest borne by or Yield to Maturity (in the case of Original
Issue Discount Securities), or prescribed therefor in, the Securities of such
series; and, in addition thereto, such further amount as shall be sufficient to
cover the costs and expense of collection, including a reasonable compensation
to the Trustee, its agents and counsel, and any expenses or liabilities
incurred, and all advances made, by the Trustee hereunder other than through its
negligence or bad faith.

     In case the Company shall fail forthwith to pay such amounts upon such
demand, the Trustee, in its own name and as Trustee of an express trust, shall
be entitled and empowered to institute any actions 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 Company or any other obligor upon such

                                       36
<PAGE>

Securities, and collect in the manner provided by law out of the property of the
Company or any other obligor upon such Securities wherever situated the moneys
adjudged or decreed to be payable.

     If an Event of Default with respect to Securities of any series occurs and
is continuing, the Trustee may in its discretion proceed to protect and enforce
its rights and the rights of the Holders of Securities of such series by such
appropriate judicial proceedings as the Trustee shall deem most effectual to
protect and enforce any such rights, whether for the specific enforcement of any
covenant or agreement in this Indenture or in aid of the exercise of any power
granted herein, or to enforce any other proper remedy.

     SECTION 6.03.  Trustee May File Proofs of Claim.  In case of the pendency
                    --------------------------------
of any receivership, insolvency, liquidation, bankruptcy, reorganization,
arrangement, adjustment, composition or other similar judicial proceeding
relative to the Company or any other obligor upon the Securities or the property
of the Company or of such other obligor or their creditors, the Trustee
(irrespective of whether the principal of the Securities of any series 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 on the Company
for the payment of overdue principal or interest) shall be entitled and
empowered, to the fullest extent permitted by law, by intervention in such
proceeding or otherwise:

          (a) to file and prove a claim for the whole amount of principal (and
premium, if any) and interest owing and unpaid in respect of the Securities (or,
if the Securities are Original Issue Discount Securities, such portion of the
principal amount as may be specified in the terms of such Securities) 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 the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel) and of the Holders allowed in such judicial proceeding; and

          (b) to collect and receive any moneys or other property payable or
deliverable on any such claims and to distribute the same;

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or
other similar official in any such judicial proceeding is hereby authorized by
each Holder to make such payments to the Trustee and, in the event that the
Trustee shall consent to the making of such payments directly to the Holders, to
pay to the Trustee any amount due it for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, and any other
amounts due the Trustee under Section 7.06.

     Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Holder any plan of
reorganization, arrangement, adjustment or composition affecting the Securities
or the rights of any Holder thereof or to authorize the Trustee to vote in
respect of the claim of any Holder in any such proceeding.

     SECTION 6.04.  Trustee May Enforce Claims Without Possession of Securities.
                    -----------------------------------------------------------

series or Coupons appertaining to such Securities, may be prosecuted and
enforced by the Trustee to the fullest

<PAGE>

extent permitted by law without the possession of any of the Securities of any
series or Coupons appertaining to such Securities, or the production thereof in
any proceeding relating thereto, and any such proceeding instituted by the
Trustee shall be brought in its own name as trustee of an express trust, and any
recovery of judgment shall, after provision for the payment of the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel, be for the ratable benefit of the Holders of the Securities or
Coupons in respect of which such judgment has been recovered.

     SECTION 6.05.  Application of Moneys Collected by Trustee.  Any moneys
                    ------------------------------------------
collected by the Trustee pursuant to Section 6.02 shall be applied in the order
following, at the date or dates fixed by the Trustee for the distribution of
such moneys, upon presentation of the several Securities or Coupons appertaining
to such Securities in respect of which moneys have been collected, and stamping
thereon the payment, if only partially paid, and upon surrender thereof if fully
paid:

          FIRST:  To the payment of all amounts due to the Trustee under Section
7.06;

          SECOND:  In case the principal of the Outstanding Securities in
respect of which moneys have been collected shall not have become due and be
unpaid, to the payment of any interest on such Securities, in the order of the
maturity of the installments of such interest, with interest upon the overdue
installments of interest (so far as permitted by law and to the extent that such
interest has been collected by the Trustee at the rate or rates of interest
borne by or Yield to Maturity (in the case of Original Issue Discount
Securities) of such Securities or prescribed therefor therein) such payments to
be made ratably to the Persons entitled thereto, without discrimination or
preference;

          THIRD:  In case the principal of the Outstanding Securities in respect
of which such moneys have been collected shall have become due, by declaration
or otherwise, to the payment of the whole amount then owing and unpaid upon such
Securities for principal and interest, if any, with interest on the overdue
principal and any installments of interest (so far as permitted by law and to
the extent that such interest has been collected by the Trustee) at the rate or
rates of interest borne by or Yield to Maturity (in the case of Original Issue
Discount Securities), or prescribed therefor in, such Securities; and in case
such moneys shall be insufficient to pay in full the whole amount so due and
unpaid upon such Securities, 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 over any other Security, ratably to the aggregate of such principal and
accrued and unpaid interest or Yield to Maturity; and

          FOURTH:  To the payment of the remainder, with appropriate interest to
the Company or its successors or assigns, or to whomsoever may be lawfully
entitled to receive the same, or as a court of competent jurisdiction may

     SECTION 6.06.  Limitation on Suits by Holders of Securities.  No Holder of
                    --------------------------------------------

right by virtue or by availing of any provision of this Indenture to institute
any suit, action or proceeding in equity or at law upon or under or with respect
to this Indenture or for the appointment of a receiver or trustee, or

                                       38
<PAGE>

for any other remedy hereunder, unless such Holder previously shall have given
to the Trustee written notice of a continuing Event of Default, as hereinbefore
provided, and unless also the Holders of not less than 25% in principal amount
of the Securities of such series then Outstanding shall have made written
request upon the Trustee to institute such action, suit or proceeding 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 (including the reasonable fees of counsel for the
Trustee), and the Trustee, for 60 days after its receipt of such notice, request
and offer of indemnity, shall have neglected or refused to institute any such
action, suit or proceeding and no direction inconsistent with such written
request shall have been given to the Trustee pursuant to this Section 6.06; it
being understood and intended, and being expressly covenanted by the taker and
Holder of every Security or Coupon with every other taker and Holder and the
Trustee, that no one or more Holders of Securities of any series or Coupons
appertaining to such Securities shall have any right in any manner whatever by
virtue or by availing of any provision of this Indenture to affect, disturb or
prejudice the rights of the Holders of any other of such Securities or Coupons
appertaining to such Securities, or to obtain or seek to obtain priority over or
preference to any other such Holder, or to enforce any right under this
Indenture, except in the manner herein provided and for the equal, ratable and
common benefit of all Holders of Securities of the applicable series and Coupons
appertaining to such Securities. For the protection and enforcement of the
provisions of this Section 6.06, each and every Holder and the Trustee shall be
entitled to such relief as can be given either at law or in equity.

     Notwithstanding any other provisions in this Indenture, the right of any
Holder of any Security or Coupon to receive payment of the principal of and
interest on such Security or Coupon on or after the respective due dates
expressed in such Security (or, in the case of redemption, on or after the date
fixed for redemption), 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 6.07.  Rights and Remedies Cumulative.  All powers and remedies
                    ------------------------------
given by this Article Six to the Trustee or to the Holders shall, to the extent
permitted by law, be deemed cumulative and not exclusive of any thereof or of
any other powers and remedies available to the Trustee or the Holders, by
judicial proceedings or otherwise, to enforce the performance or observance of
the covenants and agreements contained in this Indenture, and no delay or
omission of the Trustee or of any Holder of any of the Securities or Coupons to
exercise any right or power accruing upon any default occurring and continuing
as aforesaid shall impair any such right or power, or shall be construed to be a
waiver of any such default or an acquiescence therein; and, subject to the
provisions of Section 6.06, every power and remedy given by this Article Six or
by law to the Trustee or to the Holders may be exercised from time to time, and
as often as shall be deemed expedient, by the Trustee or by the Holders.  The
assertion or employment of any right or remedy hereunder or otherwise shall not
prevent the concurrent assertion or employment of any other appropriate right or
remedy.

     SECTION 6.08.  Delay or Omission Not Waiver.  No delay or omission of the
                    ----------------------------
Trustee or of any Holder of any Securities or Coupons to exercise any right or
remedy accruing upon any Event of Default shall impair any such right or remedy
or constitute a waiver of any such Event of Default or an acquiescence therein.
Subject to the provisions of Section 6.06, every right and

                                       39
<PAGE>

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

     SECTION 6.09.  Control by Holders; Waiver of Past Defaults.  The Holders of
                    -------------------------------------------
a majority in principal amount of the Securities of all series (voting as one
class) at the time Outstanding (determined as provided in Section 8.04) 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; provided, however, that, subject to Section 7.01 the
Trustee shall have the right to decline to follow any such direction if the
Trustee in reliance upon an Opinion of Counsel determines that the action so
directed may not lawfully be taken, or if the Trustee in good faith shall, by a
Responsible Officer or Officers of the Trustee, determine that the proceedings
so directed would be illegal or involve it in personal liability or be unduly
prejudicial to the rights of Holders not parties to such direction, and provided
further that nothing in this Indenture shall impair the right of the Trustee to
take any action deemed proper by the Trustee and which is not inconsistent with
such direction by the Holders.

     The Company may set a special record date for purposes of determining the
identity of the Holders of Securities entitled to vote or consent to any action
by vote or consent authorized or permitted by this Section 6.09.  Such record
date shall be the later of 15 days prior to the first solicitation of such
consent or the date of the most recent list of Holders furnished to the Trustee
pursuant to Section 5.01 of this Indenture prior to such solicitation.

     The Holders of not less than a majority in principal amount of the
Securities of any series at the time Outstanding (determined as provided in
Section 8.04) may on behalf of the Holders of all the Securities of such series
waive any past Event of Default with respect to such series and its consequences
(subject to Section 6.02), except a continuing Event of Default specified in
Section 6.01(a), (b) or (c), or in respect of a covenant or provision of this
Indenture which under Article Ten cannot be modified or amended without the
consent of the Holder of each Security so affected.  Upon any such waiver, the
Company, the Trustee and the Holders of the Securities of such series shall be
restored to their former positions and rights hereunder, respectively, and such
Event of Default shall be deemed to have been cured and not continuing for every
purpose of this Indenture; but no such waiver shall extend to any subsequent or
other Event of Default or impair any right consequent thereon.

     SECTION 6.10.  Trustee to Give Notice of Defaults Known to it, 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 (i) if
any Unregistered Securities of that series are then Outstanding, to the Holders
thereof, by publication at least once in an Authorized Newspaper in the Borough
of Manhattan, The City of New York and at least once in an Authorized Newspaper
in London (and, if required by Section 4.09, at least once in an Authorized
Newspaper in Luxembourg) and (ii) 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

                                       40
<PAGE>

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.

     SECTION 6.11.  Requirement of an Undertaking to Pay Costs in Certain Suits
                    -----------------------------------------------------------
Under the Indenture or Against the Trustee.  All parties to this Indenture
------------------------------------------
agree, and each Holder of any Security by such Holder's 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 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 6.11 shall not apply to
any suit instituted by the Trustee, to any suit instituted by any Holder of
Securities of any series, or group of such Holders, holding in the aggregate
more than ten percent in principal amount of the Securities of such series
Outstanding, or to any suit instituted by any Holder for the enforcement of the
payment of the principal of or any interest or premium on any Security, on or
after the due date expressed in such Security or for such interest (or in the
case of any redemption, on or after the dated fixed for redemption).

     SECTION 6.12.  Waiver of Stay or Extension Laws  The Company covenants (to
                    --------------------------------
the extent that it may lawfully do so) that it will not at any time insist upon,
or plead, or in any manner whatsoever claim or take the benefit or advantage of,
any stay or extension law wherever enacted, now or at any time hereafter in
force, which may affect the covenants or the performance of this Indenture; and
the Company (to the extent that it may lawfully do so) hereby expressly waives
all benefit or advantage of any such law and covenants that they 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.

                            CONCERNING THE TRUSTEE

     SECTION 7.01.  Certain Duties and Responsibilities of Trustee.  The
                    ----------------------------------------------
Trustee, prior to the occurrence of an Event of Default and after the curing,
remedying or waiving of all Events of Default which may have occurred,
undertakes to perform such duties and only such duties as are specifically set
forth in this Indenture.  In case an Event of Default has occurred (which has
not been cured, remedied or waived), the Trustee shall exercise such of the
rights and powers vested in it by this Indenture, and use the same degree of
care and skill in their exercise, as a prudent man 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, provided, however, that:

     (a) prior to the occurrence of an Event of Default and after the curing,
remedying or waving of all Events of Default which may have occurred:

                                       41
<PAGE>

          (1) the duties and obligations of the Trustee 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

          (2) 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 certificates or opinions
furnished to the Trustee and conforming to the requirements of this Indenture;
but in the case of any such certificates or opinions which by any provision
hereof are specifically required to be furnished to the Trustee, the Trustee
shall be under a duty to examine the same to determine whether or not they
conform to the requirements of this Indenture;

     (b) the Trustee shall not be liable for any error of judgment made in good
faith by a Responsible Officer or 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 of Securities pursuant to Section 6.09 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 hereunder or in the exercise
of any of its rights or powers, if there is reasonable ground for believing that
the repayment of such funds or adequate indemnity against such risk or liability
is not reasonably assured to it.

     SECTION 7.02.  Certain Rights of Trustee.  Except as otherwise provided in
                    -------------------------
Section 7.01:

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

     (b) Any request, direction, order or demand of the Company mentioned herein
shall be sufficiently evidenced by an Officer's Certificate (unless other
evidence in respect thereof shall be herein specifically prescribed); and any
resolution of the Board of Directors may be evidenced to the Trustee by a Board
Resolution;

     (c) The Trustee may consult with counsel and the written advice of such
counsel or any Opinion of Counsel shall be full and complete authorization and
protection in respect of any action taken, suffered or omitted by it hereunder
in good faith and in accordance with such written advice or Opinion of Counsel;

                                       42
<PAGE>

     (d) The Trustee shall be under no obligation to exercise any of the rights
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 may 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 or
rights or powers conferred upon it by this Indenture;

     (f) 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, bond, debenture,
note or other paper or document, unless requested in writing so to do by the
Holders of Securities pursuant to Section 6.09; provided, however, 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 costs, expenses or liabilities as a condition
to such proceeding; and provided further, that nothing in this subsection (f)
shall require the Trustee to give the Securityholders any notice other than that
required by Section 6.10. The reasonable expense of every such examination shall
be paid by the Company or, if paid by the Trustee, shall be reimbursed by the
Company upon demand;

     (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 and the Trustee shall not be responsible for any misconduct or
negligence on the part of any agent or attorney appointed with due care by it
hereunder; and

     (h) The Trustee shall be under no responsibility for the approval by it in
good faith of any expert for any of the purposes expressed in this Indenture.

                    ------------------------------------------------------
Proceeds.  The recitals contained herein and in the Securities (other than the
--------
certificate of authentication on the Securities) shall be taken as the
statements of the Company, and the Trustee assumes no responsibility for the
correctness of the same.  The Trustee makes no representations 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 Company of any of the
Securities or of the proceeds thereof.

     SECTION 7.04.  Trustee May Own Securities or Coupons.  The Trustee, any
                    -------------------------------------
Paying Agent, registrar or any agent of the Company or of the Trustee, in its
individual or any other capacity, may become the owner or pledgee of Securities
or Coupons with the same rights it would have if it were not Trustee, Paying

     SECTION 7.06.  Trustee Entitled to Compensation, Reimbursement and
                    ---------------------------------------------------
Indemnity.  The Company agrees to pay to the Trustee from time to time
---------
reasonable compensation (which shall not be limited by any provision of law in
regard to the compensation of a trustee of any express trust), and the Company
will pay or reimburse the Trustee upon its request for all reasonable expenses,
disbursements and advances incurred or made by the Trustee in connection with
the acceptance or administration of its trust under this Indenture (including
the reasonable compensation and the expenses and disbursements of its counsel
and of all Persons not regularly in its employ) except any such expense,
disbursement or advance as may arise from its negligence or bad faith.  The
Company also agrees to indemnify the Trustee for, and to hold it harmless
against, any loss, liability or expense incurred without negligence or bad faith
on the part of the Trustee and arising out of or in connection with the

expenses of defending itself against any claim of liability in the premises.
The obligations of the Company under this Section to compensate the Trustee, to
pay or reimburse the Trustee for expenses, disbursements and advances and to
indemnify and hold harmless the Trustee shall constitute additional indebtedness
hereunder and shall survive the satisfaction and discharge of this Indenture.
Such additional indebtedness shall be secured by a lien prior 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 payment of principal of or interest or
redemption premium on particular Securities.

     SECTION 7.07.  Right of Trustee to Rely on Officer's Certificate Where No
                    ----------------------------------------------------------
Other Evidence Specifically Prescribed.  Except as otherwise provided in Section
--------------------------------------
7.01, whenever in the administration of the provisions of this Indenture the
Trustee shall deem it necessary or desirable that a matter be proved or
established prior to taking, 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 bad faith on the part of the
Trustee, be deemed to be conclusively proved and established by an Officer's
Certificate of the Company delivered to the Trustee, and such Officer's
Certificate, in the absence of negligence or bad faith 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 7.08.  Disqualification; Conflicting Interest.  (a)  If the Trustee
                    --------------------------------------
has or shall acquire any conflicting interest, as defined in this Section 7.08,
it shall, within 90 days after ascertaining that it has such conflicting
interest, and if the Event of Default to which such conflicting interest relates
has not been cured or duly waived or otherwise eliminated before the end of such
90-day period, the Trustee shall either eliminate such conflicting interest or,
except as otherwise provided in this Section 7.08, resign in the manner and with
the effect specified in Section 7.10, such resignation to become effective upon
the appointment of a successor trustee and such successor's acceptance of such
appointment, and the Company shall take prompt steps to appoint a successor in
accordance with Section 7.10.

     (b) In the event that the Trustee shall fail to comply with the provisions
of subsection (a) of this Section 7.08, the Trustee shall, within ten days after
the expiration of such 90-day period, transmit notice of such failure to the
Securityholders in the manner and to the extent provided in subsection (c) of
Section 5.04 with respect to reports pursuant to subsection (a) of said Section
5.04.

<PAGE>

     (c) Subject to the provisions of Section 6.11 of this Indenture, unless the
Trustee's duty to resign is stayed as provided in subsection (f) of this Section
7.08, any Holder who has been a bona fide Holder of Securities for at least six
months may, on such Holder's behalf and on behalf of all other Holders similarly
situated, petition any court of competent jurisdiction for the removal of such
Trustee and the appointment of a successor, if such Trustee fails after written
request thereof by such Holder to comply with the provisions of subsection (a)
of this Section 7.08.

     (d) For the purposes of this Section 7.08 the Trustee shall be deemed to
have a conflicting interest with respect to the Securities of any series if an
Event of Default (exclusive of any period of grace or requirement of notice) has
occurred with respect to Securities of such series and:

          (1) the Trustee is trustee under another indenture under which any
other securities, or certificates of interest or participation in any other
securities, of the Company or any other obligor on the Securities are
outstanding or is trustee for more than one outstanding series of securities, as
hereinafter defined, under a single indenture of the Company or any other
obligor on the Securities, unless such other indenture is a collateral trust
indenture under which the only collateral consists of Securities issued under
this Indenture, provided that there shall be excluded from the operation of this
paragraph, this Indenture with respect to the Securities of any other series
Outstanding, and any other indenture or indentures under which other securities,
or certificates of interest or participation in other securities, of the Company
or any other obligor on the Securities are outstanding, if (A) this Indenture is
and such other indenture or indentures (and all series of securities issued
thereunder) are wholly unsecured and rank equally, and such other indenture or
indentures (and such series) are hereafter qualified under the Trust Indenture
Act, unless the Commission shall have found and declared by order pursuant to
subsection (b) of Section 305 or subsection (c) of Section 307 of the Trust
Indenture Act, that differences exist between the provisions of this Indenture
with respect to Securities of such series and one or more other series, or the
provisions of this Indenture and the provisions of such other indenture or
indentures (or such series), which are so likely to involve a material conflict
of interest as to make it necessary in the public interest or for the protection
of investors to disqualify the Trustee from acting as such under this Indenture
with respect to Securities of such series and such other series, or under this
Indenture and such other indenture or indentures, or (B) the Company shall have
sustained the burden of proving, on application to the Commission and after
opportunity for hearing thereon, that the trusteeship under this Indenture with
respect to Securities of such series and such other series, or under this
Indenture and such other indenture, is not so likely to involve a material
conflict of interest as to make it necessary in the public interest or for the
protection of investors to disqualify the Trustee from acting as such under this
Indenture with respect to Securities of such series and such other series, or
under this Indenture and one of such indentures;

          (2) the Trustee or any of its directors or executive officers is an
underwriter for the Company or any other obligor on the Securities;

          (3) the Trustee directly or indirectly controls or is directly or
indirectly controlled by or is under direct or indirect common control with an
underwriter for the Company or any other obligor on the Securities;

                                       45
<PAGE>

          (4) the Trustee or any of its directors or executive officers is a
director, officer, partner, employee, appointee or representative of the Company
or any other obligor on the Securities, or of an underwriter (other than the
Trustee itself) for the Company or any other obligor on the Securities who is
currently engaged in the business of underwriting, except that (A) one
individual may be a director and/or an executive officer of the Trustee and a
director and/or an executive officer of the Company or any other obligor on the
Securities, but may not     be at the same time an executive officer of both the
Trustee and the Company or any other obligor on the Securities; (B) if and so
long as the number of directors of the Trustee in office is more than nine, one
additional individual may be a director and/or an executive officer of the
Trustee and a director of the Company or any other obligor on the Securities;
and (C) the Trustee may be designated by the Company or any other obligor on the
Securities or by an underwriter for the Company or any other obligor on the
Securities to act in the capacity of transfer agent, registrar, custodian,
paying agent, fiscal agent, escrow agent or depositary, or in any other similar
capacity, or, subject to the provisions of paragraph (1) of this subsection (d),
to act as trustee whether under an indenture or otherwise;

          (5) ten percent or more of the voting securities of the Trustee is
beneficially owned either by the Company or any other obligor on the Securities
or by any director, partner or executive officer thereof, or 20% or more of such
voting securities is beneficially owned, collectively, by any two or more of
such Persons; or ten percent or more of the voting securities of the Trustee is
beneficially owned either by an underwriter for the Company or any other obligor
on the Securities or by any director, partner or executive officer thereof or is
beneficially owned, collectively, by any two or more such Persons;

          (6) the Trustee is the beneficial owner of, or holds as collateral
security for an obligation which is in default, as hereinafter defined, (A) five
percent or more of the voting securities, or ten percent or more of any other
class of security, of the Company or any other obligor on the Securities, not
including the Securities issued under this Indenture and securities issued under
any other indenture under which the Trustee is also trustee, or (B) ten percent
or more of any class of security of an underwriter for the Company or any other
obligor on the Securities;

          (7) the Trustee is the beneficial owner of, or holds as collateral
security for an obligation which is in default, as hereinafter defined, five
percent or more of the voting securities of any Person who, to the knowledge of
the Trustee, owns ten percent or more of the voting securities of, or controls
directly or indirectly or is under direct or indirect common control with the
Company or any other obligor on the Securities;

          (8) the Trustee is the beneficial owner of, or holds as collateral
security for an obligation which is in default, as hereinafter defined, ten
percent or more of any class of security of any Person who, to the knowledge of
the Trustee, owns 50% or more of the voting securities of the Company or any
other obligor on the Securities; or

          (9) the Trustee owns on the date of the occurrence of such Event of
Default (exclusive of any period of grace or requirement of notice) or any
anniversary thereof while such Event of Default remains outstanding, in the
capacity of executor, administrator, testamentary or inter vivos trustee,
guardian, committee or conservator, or in any other similar capacity an
aggregate of 25% or more of the voting securities or of any class of security,
of any Person, the

                                       46
<PAGE>

beneficial ownership of a specified percentage of which would have constituted a
conflicting interest under paragraph (6), (7) or (8) of this subsection (d). As
to any such securities of which the Trustee acquired ownership through becoming
executor, administrator or testamentary trustee of an estate which included
them, the provisions of the preceding sentence shall not apply, for a period of
two years from the date of such acquisition, to the extent that such securities
included in such estate do not exceed 25% of such voting securities or 25% of
any such class of security. Promptly after the date of the occurrence of any
such Event of Default and annually in each succeeding year that the Securities
or any series thereof remain in default, the Trustee shall make a check of its
holdings of such securities in any of the above-mentioned capacities as of such
date. If the Company or any other obligor on the Securities fails to make
payment in full of principal of or interest on any of the Securities when and as
the same become due and payable and such failure continues for 30 days
thereafter, the Trustee shall make a prompt check of its holdings of such
securities in any of the above-mentioned capacities as of the date of the
expiration of such 30-day period, and after such date, notwithstanding the
foregoing provisions of this paragraph (9), all such securities so held by the
Trustee, with sole or joint control over such securities vested in it, shall,
but only so long as such failure shall continue, be considered as though
beneficially owned by the Trustee for the purposes of paragraphs (6), (7) and
(8) of this subsection (d); or

          (10) except under the circumstances described in paragraphs (1), (3),
(4), (5) or (6) of Section 7.13(b), the Trustee shall be or become a creditor of
the Company or any other obligor on the Securities.

     The specifications of percentages in paragraphs (5) to (9), inclusive, of
this subsection (d) shall not be construed as indicating that the ownership of
such percentages of the securities of a Person is or is not necessary or
sufficient to constitute direct or indirect control for the purposes of
paragraph (3) or (7) of this subsection (d).

     For the purposes of paragraphs (6), (7), (8) and (9) of this subsection (d)
only, (A) the terms "security" and "securities" shall include only such
securities as are generally known as corporate securities, but shall not include
any note or other evidence of indebtedness issued to evidence an obligation to
repay moneys lent to a Person by one or more banks, trust companies or banking
firms, or any certificate of interest or participation in any such note or
evidence of indebtedness; (B) an obligation shall be deemed to be in default
when a default in payment of principal shall have continued for 30 days or more
and shall not have been cured; and (C) the Trustee shall not be deemed to be the
owner or Holder of (i) any security which it holds as collateral security (as
trustee or otherwise) for an obligation which is not in default as defined in
clause (B) above, or (ii) any security which it holds as collateral security
under this Indenture, irrespective of any default hereunder, or (iii) any
security which it holds as agent for collection, or as custodian, escrow agent
or depositary, or in any similar representative capacity.

     (e) For the purposes of this Section 7.08:

          (1) The term "underwriter" when used with reference to the Company or
any other obligor on the Securities shall mean every Person who, within one year
prior to the time as of which the determination is made, has purchased from the
Company or any other obligor on the Securities with a view to, or has offered or
sold for the Company or

                                       47
<PAGE>

any other obligor on the Securities in connection with, the distribution of any
security of the Company or any other obligor on the Securities outstanding at
such time, or has participated or has had a direct or indirect participation in
any such undertaking, or has participated or has had a participation in the
direct or indirect underwriting of any such undertaking, but such term shall not
include a Person whose interest was limited to a commission from an underwriter
or dealer not in excess of the usual and customary distributors' or sellers'
commission.

          (2) The term "director" shall mean any director of a Company or any
individual performing similar functions with respect to any organization whether
incorporated or unincorporated.

          (3) The term "trust" shall include only a trust where the interest or
interests of the beneficiary or beneficiaries are evidenced by a security.

          (4) The term "voting security" shall mean any security presently
entitling the owner or Holder thereof to vote in the direction or management of
the affairs of a Person, or any security issued under or pursuant to any trust,
agreement or arrangement whereby a trustee or trustees or agent or agents for
the owner or Holder of such security are presently entitled to vote in the
direction or management of the affairs of a Person.

          (5) The term "executive officer" shall mean the president, every vice-
president, every trust officer, the cashier, the secretary and the treasurer of
a Company, and any individual customarily performing similar functions with
respect to any organization whether incorporated or unincorporated, but shall
not include the chairman of the board of directors.

          (6) Except for purposes of paragraphs (6), (7), (8) and (9) of
subsection (d) of this Section 7.08, the term "security" or "securities" shall
mean any note, stock, treasury stock, bond, debenture, evidence of indebtedness,
certificate of interest or participation in any profit-sharing agreement,
collateral-trust certificate, pre-organization certificate or subscription,
transferable share, investment contract, voting-trust certificate, certificate
of deposit for a security, fractional undivided interest in oil, gas or other
mineral rights, or, in general, any interest or instrument commonly known as a
"security" or any certificate of interest or participation in, temporary or
interim certificate for, receipt for, guarantee of, or warrant or right to
subscribe to or purchase, any of the foregoing.

          (7) For the purpose of subsection (d)(1) of this Section 7.08, the
term "series of securities" or "series" means a series, class or group of
securities issuable under an indenture pursuant to whose terms Holders of one
such series may vote to direct the indenture trustee, or otherwise take action
pursuant to a vote of such holders, separately from holders of another such
series; provided, that "series of securities" or "series" shall not include any
series of securities issuable under an indenture if all such series rank equally
and are wholly unsecured.

     The percentages of voting securities and other securities specified in this
Section shall be calculated in accordance with the following provisions:

          (A) A specified percentage of the voting securities of the Trustee,
the Company or any other Person referred to in this Section 7.08 (each of whom
is referred to as a "Person" in this paragraph) means such amount of the
outstanding voting securities of such Person as entitles the Holder or Holders
thereof to cast such specified percentage of the

                                       48
<PAGE>

aggregate votes which the Holders of all the outstanding voting securities of
such Person are entitled to cast in the direction or management of the affairs
of such Person.

          (B) A specified percentage of a class of securities of a Person means
such percentage of the aggregate amount of securities of the class outstanding.

          (C) The term "amount", when used in regard to securities, means the
principal amount if relating to evidences of indebtedness, the number of shares
if relating to capital shares, and the number of units if relating to any other
kind of security.

          (D) The term "outstanding" means issued and not held by or for the
account of the issuer.  The following securities shall not be deemed outstanding
within the meaning of this definition:

               (i)   Securities of an issuer held in a sinking fund relating to
securities of the issuer of the same class;

               (ii)  Securities of an issuer held in a sinking fund relating to
another class of securities of the issuer, if the obligation evidenced by such
other class of securities is not in default as to principal or interest or
otherwise;

               (iii) Securities pledged by the issuer thereof as security for an
obligation of the issuer not in default as to principal or interest or
otherwise; and

               (iv)  Securities held in escrow if placed in escrow by the issuer
thereof;

provided, however, that any voting securities of an issuer shall be deemed
outstanding if any Person other than the issuer is entitled to exercise the
voting rights thereof.

          (E)  A security shall be deemed to be of the same class as another
security if both securities confer upon the Holder or Holders thereof
substantially the same rights and privileges, provided, however, that, in the
case of secured evidences of indebtedness, all of which are issued under a
single indenture, differences in the interest rates or maturity dates of various
series thereof shall not be deemed sufficient to constitute such series
different classes, and provided further that, in the case of unsecured evidences
of indebtedness, differences in the interest rate or maturity dates thereof
shall not be deemed sufficient to constitute them securities of different
classes, whether or not they are issued under a single indenture.

     (f) Except in the case of a default in the payment of the principal of or
interest on any Securities, or in the payment of any sinking or purchase fund
installment, the Trustee shall not be required to resign as provided by this
Section 7.08 if the Trustee shall have sustained the burden of proving, on
application to the Commission and after opportunity for hearing thereon, that
(i) the default under this Indenture may be cured or waived during a reasonable
period and under the procedures described in such application, and (ii) a stay
of the Trustee's duty to resign will not be inconsistent with the interests of
Holders of such series of Securities.  The filing of such an application shall
automatically stay the performance of the duty to resign until the Commission
orders otherwise.  Any resignation of the Trustee shall become effective only
upon the appointment of a successor trustee and such successor's acceptance of
such appointment.

     SECTION 7.09.  Requirements for Eligibility of Trustee.  There shall always
                    ---------------------------------------

and, in each case, authorized under such laws to exercise corporate trust
powers, having a combined capital and surplus of at least $50,000,000, and
subject to supervision or examination by Federal, State or District of Columbia
authority.  If such Company 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 Company shall be deemed to be its combined capital and surplus
as set forth in its most recent report of condition so published. No obligor on
the Securities or Person directly or indirectly controlling, controlled by or
under common control with such obligor shall serve as Trustee.  In case at any
time the Trustee shall cease to be eligible in accordance with the provisions of
this Section 7.09, the Trustee shall resign immediately in the manner and with
the effect specified in this Article Seven.

     SECTION 7.10.  Resignation and Removal of Trustee; Appointment of
                    --------------------------------------------------
Successor.
---------

     (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 Company and (i) if any Unregistered
Securities of a series affected are then Outstanding, by giving notice of such
resignation to the Holders thereof, by publication at least once in an
Authorized Newspaper in the Borough of Manhattan, The City of New York, and at
least once in an Authorized Newspaper in London (and, if required by Section
4.09, at least once in an Authorized Newspaper in Luxembourg), (ii) if any
Unregistered Securities of a series affected are then Outstanding, by mailing
notice of such resignation to the Holders thereof who have filed their names and
addresses with the Trustee pursuant to Section 313(c)(2) of the Trust Indenture
Act at such addresses as were so furnished to the Trustee and (iii) 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 Company 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:

          (1) the Trustee shall fail to comply with the provisions of subsection
(a) of Section 7.08 after written request therefor by the Company or by any
Securityholder who has been a bona fide Holder of a Security or Securities of
the applicable series for at least six months; or

                                       50
<PAGE>

          (2) the Trustee shall cease to be eligible in accordance with the
provisions of Section 7.09 and shall fail to resign after written request
therefor by the Company or by any such Securityholder; or

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

          (4) the Company shall determine that the Trustee has failed to perform
its obligations under this Indenture in any material respect, then, in any such
case, the Company may remove the Trustee and appoint a successor trustee by
written instrument executed by an authorized officer of the Company, 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 6.11, any
Securityholder who has been a bona fide Holder of a Security or Securities of
the affected series for at least six months may, on such Person's behalf and on
behalf of 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 prescribe, remove the Trustee and
appoint a successor trustee.

     (c) The Holders of a majority in principal amount of the Securities
Outstanding (determined as provided in Section 8.04) may at any time remove the
Trustee and appoint a successor trustee by written instrument or instruments
signed by such Holders or their attorneys-in-fact duly authorized, or by the
affidavits of the permanent chairman and secretary of a meeting of the
Securityholders evidencing the vote upon a resolution or resolutions submitted
thereto with respect to such removal and appointment (as provided in Article
Nine), and by delivery thereof to the Trustee so removed, to the successor
trustee and to the Company.

     (d) Any resignation or removal of the Trustee and any appointment of a
successor trustee pursuant to any of the provisions of this Section 7.10 shall
become effective upon acceptance of appointment by the successor trustee as
provided in Section 7.11.

     SECTION 7.11.  Acceptance of Appointment by Successor Trustee.  Any
                    ----------------------------------------------
successor trustee appointed as provided in Section 7.10 shall execute,
acknowledge and deliver to the Company and to its predecessor trustee an
instrument accepting such appointment hereunder, and thereupon the resignation
or removal of the predecessor trustee shall become effective and such successor
trustee, without any further act, deed or conveyance, shall become vested with
all the rights, powers, duties and obligations with respect to such series of
its predecessor hereunder, with like effect as if originally named as trustee
herein; but, nevertheless, on the written request of the Company or of the
successor trustee, the trustee ceasing to act shall, upon payment of any amounts
then due it pursuant to the provisions of Section 7.06, execute and deliver an
instrument transferring to such successor trustee all the rights and powers with
respect to the trustee so ceasing to act.  Upon written request of any such
successor trustee, the Company 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 lien upon all property or funds held or collected by such trustee to
secure any amounts then due it pursuant to the provisions of Section 7.06.

                                       51
<PAGE>

     No successor trustee shall accept appointment as provided in this Section
7.11 unless at the time of such acceptance such successor trustee shall be
qualified under the provisions of Section 7.08 and eligible under the provisions
of Section 7.09.

     Upon acceptance of appointment by a successor trustee as provided in this
Section 7.11, the Company shall give notice thereof (a) if any Unregistered
Securities of a series affected are then Outstanding, to the Holders thereof, by
publication of such notice at least once in an Authorized Newspaper in the
Borough of Manhattan, The City of New York and at least once in an Authorized
Newspaper in London (and, if required by Section 3.09, at least once in an
Authorized Newspaper in Luxembourg), (b) if any Unregistered Securities of a
series affected are then Outstanding, to the Holders thereof who have filed
their names and addresses with the Trustee pursuant to Section 313(c)(2) of the
Trust Indenture Act, by mailing such notice to such Holders at such addresses as
were so furnished to the Trustee (and the Trustee shall make such information
available to the Company for such purpose) and (c) 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 7.10.  If the Company fails to give such notice within ten
days after acceptance of appointment by the successor trustee, the successor
trustee shall cause such notice to be given at the expense of the Company.

     SECTION 7.12.  Successor to Trustee by Merger, Consolidation or Succession
                    -----------------------------------------------------------
to Business.  Any Company into which the Trustee may be merged or converted or
-----------
with which it may be consolidated, or any Company resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any
Company succeeding to all or substantially all of the corporate trust business
of the Trustee, shall be the successor of the Trustee hereunder, provided such
Company shall be qualified under the provisions of Section 7.08 and eligible
under the provisions of Section 7.09, 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.

     In case at the time such successor to the Trustee shall succeed to the
trusts created by this Indenture any of the Securities 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
shall not have been authenticated, any 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 certificates shall have the
full force which it is anywhere in the Securities or in this Indenture provided
that the certificate of the Trustee shall have; provided, however, that the
right to adopt the certificate of authentication of any predecessor Trustee or
to authenticate Securities in the name of any predecessor Trustee shall apply
only to its successor or successors by merger, conversion or consolidation.

     SECTION 7.13.  Preferential Collection of Claims Against Company.  (a)
                    -------------------------------------------------
Subject to the provisions of subsection (b) of this Section 7.13, if the Trustee
shall be or shall become a creditor, directly or indirectly, secured or
unsecured, of the Company or any other obligor on the Securities within three
months prior to a default, as defined in subsection (c) of this Section 7.13, or
subsequent to such a default, then, unless and until such default shall be
cured, the Trustee shall set apart and hold in a special account for the benefit
of the Trustee individually, the

                                       52
<PAGE>

Holders of the Securities for which it is acting as Trustee, and the holders of
other indenture securities (as defined in subsection (c) of this Section 7.13):

          (1) an amount equal to any and all reductions in the amount due and
owing upon any claim as such creditor in respect of principal or interest,
effected after the beginning of such three months' period, and valid as against
the Company or such other obligor on the Securities and its other creditors,
except any such reduction resulting from the receipt or disposition of any
property described in paragraph (2) of this subsection, or from the exercise of
any right of set-off which the Trustee could have exercised if a petition in
bankruptcy had been filed by or against the Company or such other obligor on the
Securities upon the date of such default; and

          (2) all property received by the Trustee in respect of any claims as
such creditor, either as security therefor, or in satisfaction or composition
thereof, or otherwise, after the beginning of such three months' period, or an
amount equal to the proceeds of any such property if disposed of, subject,
however, to the rights, if any, of the Company or such other obligor on the
Securities and their respective other creditors in such property or such
proceeds.

     Nothing herein contained, however, shall affect the right of the Trustee:

          (A) to retain for its own account (i) payments made on account of any
such claim by any Person (other than the Company or such other obligor on the
Securities) who is liable thereon, and (ii) the proceeds of the bona fide sale
of any such claim by the Trustee to a third Person, and (iii) distributions made
in cash, securities or other property in respect of claims filed against the
Company or such other obligor on the Securities in bankruptcy or receivership or
in proceedings for reorganization pursuant to Title 11 of the United States Code
or applicable State laws;

          (B) to realize, for its own account, upon any property held by it as
security for any such claim, if such property was so held prior to the beginning
of such three months' period;

          (C) to realize, for its own account, but only to the extent of the
claim hereinafter mentioned, upon any property held by it as security for any
such claim, if such claim was created after the beginning of such three months'
period and such property was received as security therefor simultaneously with
the creation thereof, and if the Trustee shall sustain the burden of proving
that at the time such property was so received, the Trustee had no reasonable
cause to believe that a default, as defined in subsection (c) of this Section
7.13, would occur within three months; or

          (D) to receive payment on any claim referred to in paragraph (B) or
(C), against the release of any property held as security for such claim as
provided in such paragraph (B) or (C), as the case may be, to the extent of the
fair value of such property.

     For the purposes of paragraphs (B), (C) and (D), property substituted after
the beginning of such three months' period for property held as security at the
time of such substitution shall, to the extent of the fair value of the property
released, have the same status as the property released, and to the extent that
any claim referred to in any of such paragraphs is created in renewal of or

                                       53
<PAGE>

in substitution for or for the purpose of repaying or refunding any preexisting
claim of the Trustee as such creditor, such claim shall have the same status as
such preexisting claim.

     If the Trustee shall be required to account, the funds and property held in
such special account and the proceeds thereof shall be apportioned among the
Trustee, the Holders of Securities for which it is acting as Trustee, and the
holders of other indenture securities in such manner that the Trustee, such
Securityholders and the holders of other indenture securities realize, as a
result of payments from such special account and payments of dividends on claims
filed against the Company or such other obligor on the Securities in bankruptcy
or receivership or in proceedings for reorganization pursuant to Title 11 of the
United States Code or applicable State law, the same percentage of their
respective claims, figured before crediting to the claim of the Trustee anything
on account of the receipt by it from the Company or such other obligor on the
Securities of the funds and property in such special account and before
crediting to the respective claims of the Trustee, such Securityholders, and the
holders of other indenture securities dividends on claims filed against the
Company or such other obligor on the Securities in bankruptcy or receivership or
in proceedings for reorganization pursuant to Title 11 of the United States Code
or applicable State law, but after crediting thereon receipts on account of the
indebtedness represented by their respective claims from all sources other than
from such dividends and from the funds and property so held in such special
account.  As used in this paragraph, with respect to any claim, the term
"dividends" shall include any distribution with respect to such claim in
bankruptcy or receivership or in proceedings for reorganization pursuant to
Title 11 of the United States Code or applicable State law, whether such
distribution is made in cash, securities or other property, but shall not
include any such distribution with respect to the secured portion, if any, of
such claim.  The court in which such bankruptcy, receivership or proceeding for
reorganization is pending shall have jurisdiction (i) to apportion among the
Trustee, such Securityholders, and the holders of other indenture securities, in
accordance with the provisions of this paragraph, the funds and property held in
such special account and the proceeds thereof, or (ii) in lieu of such
apportionment in whole or in part, to give to the provisions of this paragraph
due consideration in determining the fairness of the distributions to be made to
the Trustee, such Securityholders and the holders of other indenture securities
with respect to their respective claims, in which event it shall not be
necessary to liquidate or to appraise the value of any securities or other
property held in such special account or as security for any such claim, or to
make a specific allocation of such distributions as between the secured and
unsecured portions of such claim, or otherwise to apply the provisions of this
paragraph as a mathematical formula.

     Any Trustee who has resigned or been removed after the beginning of such
three months' period shall be subject to the provisions of this subsection (a)
as though such resignation or removal had not occurred.  If any Trustee has
resigned or been removed prior to the beginning of such three months' period, it
shall be subject to the provisions of this subsection (a) if and only if the
following conditions exist:

          (i)   the receipt of property or reduction of claim which would have
given rise to the obligation to account, if such Trustee had continued, as
trustee, occurred after the beginning of such three months' period; and

          (ii)  such receipt of property or reduction of claim occurred within
three months after such resignation or removal.

                                       54
<PAGE>

     In every case commenced under the Bankruptcy Act of 1898, or any amendment
thereto enacted prior to November 6, 1978, all references to periods of three
months shall be deemed to be references to periods of four months.

     (b) There shall be excluded from the operation of subsection (a) of this
Section 7.13 a creditor relationship arising from:

          (1) the ownership or acquisition of securities issued under any
indenture, or any security or securities having a maturity of one year or more
at the time of acquisition by the Trustee;

          (2) advances authorized by a receivership or bankruptcy court of
competent jurisdiction, or by this Indenture, for the purpose of preserving any
property which shall at any time be subject to the lien of this Indenture or of
discharging tax liens or other prior liens or encumbrances thereon, if notice of
such advance and of the circumstances surrounding the making thereof is given to
the Securityholders at the time and in the manner provided in Section 5.04(c)
with respect to reports pursuant to subsections (a) and (b) thereof,
respectively;

          (3) disbursements made in the ordinary course of business in the
capacity of trustee under an indenture, transfer agent, registrar, custodian,
paying agent, fiscal agent or depositary, or other similar capacity;

          (4) an indebtedness created as a result of services rendered or
premises rented, or an indebtedness created as a result of goods or securities
sold in a cash transaction as defined in subsection (c) of this Section 7.13;

          (5) the ownership of stock or of other securities of a Company
organized under the provisions of Section 25(a) of the Federal Reserve Act, as
amended, which is directly or indirectly a creditor of the Company or any other
obligor on the Securities; and

          (6) the acquisition, ownership, acceptance or negotiation of any
drafts, bills of exchange, acceptances or obligations which fall within the
classification of self-liquidating paper as defined in subsection (c) of this
Section 7.13.

     (c) As used in this Section 7.13 the following terms shall be accorded the
following definitions:

          (1) the term "default" shall mean any failure to make payment in full
of the principal of or interest on any of the Securities or on the other
indenture securities when and as such principal or interest becomes due and
payable.

          (2) the term "other indenture securities" shall mean securities upon
which the Company or any other obligor on the Securities is an "obligor" (as
defined in the Trust Indenture Act) outstanding under any other indenture (A)
under which the Trustee is also trustee, (B) which contains provisions
substantially similar to the provisions of subsection (a) of this Section 7.13,
and (C) under which a default exists at the time of the apportionment of the
funds and property held in said special account.

                                       55
<PAGE>

          (3) the term "cash transaction" shall mean any transaction in which
full payment for goods or securities sold is made within seven days after
delivery of the goods or securities in currency or in checks or other orders
drawn upon banks or bankers and payable upon demand.

          (4) the term "self-liquidating paper" shall mean any draft, bill of
exchange, acceptance or obligation which is made, drawn, negotiated or incurred
by the Company or any other obligor on the Securities for the purpose of
financing the purchase, processing, manufacture, shipment, storage or sale of
goods, wares or merchandise and which is secured by documents evidencing title
to, possession of, or a lien upon, the goods, wares or merchandise or the
receivables or proceeds arising from the sale of the goods, wares or merchandise
previously constituting the security, provided the security is received by the
Trustee simultaneously with the creation of the creditor relationship with the
Company or any other obligor on the Securities arising from the making, drawing,
negotiating or incurring of the draft, bill of exchange, acceptance or
obligation.

     SECTION 7.14.  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 Company 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 2.09.
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
7.09 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 Company.

     Upon receiving such a notice of resignation or upon such a termination, or
in case in any time any Authenticating Agent shall cease to be eligible in
accordance with the provisions of this Section 7.14 with respect to one or more
series of Securities, the Trustee shall upon receipt of a Company Order appoint
a successor Authenticating Agent and the Company shall provide notice of such
appointment to all Holders of Securities of such series in the manner and to the
extent provided in Section 13.02.  Any successor Authenticating Agent upon
acceptance of its

                                       56
<PAGE>

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 Company 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.

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

     This is one of the Securities described in the within-mentioned Indenture.

                              Chase Manhattan Bank and Trust Company, National
                              Association, As Trustee

                              By ____________________________________
                                              As Authenticating Agent

                              By ____________________________________
                                                   Authorized Officer

     Sections 7.02, 7.03, 7.04, 7.06 and 8.03 shall be applicable to any
Authenticating Agent.

                                 ARTICLE EIGHT

                        CONCERNING THE SECURITYHOLDERS

     SECTION 8.01.  Evidence of Action by Securityholders. Whenever in this
                    -------------------------------------
Indenture it is provided that the Holders of a specified percentage in principal
amount of the Securities of any or all series may take any action (including the
making of any demand or request, the giving of any notice, consent or waiver or
the taking of any other action), the fact that at the time of taking any such
action the Holders of such specified percentage have joined therein may be
evidenced (a) by any instrument or any number of instruments of similar tenor
executed by such Securityholders in Person or by agent or proxy appointed in
writing, or (b) by the record of such Holders of Securities voting in favor
thereof at any meeting of such Securityholders duly called and held in
accordance with the provisions of Article Nine, or (c) by a combination of such
instrument or instruments and any such record of such a meeting of such
Securityholders.

     SECTION 8.02.  Proof of Execution of Instruments and of Holding of
                    ---------------------------------------------------
Securities.  Subject to the provisions of Sections 7.01, 7.02 and 9.05, proof of
----------
the execution of any instrument by a Securityholder or such Holder's agent or
proxy and proof of the holding by any Person of any of the Securities shall be
sufficient if made in the following manner:

     (a) The fact and date of the execution by any such Person of any instrument
may be proved in any reasonable manner acceptable to the Trustee;

     (b) The ownership of Securities of any series (including Registered Global
Securities) shall be proved by the Register of such Securities of such series,
or by certificates of the Security registrar or registrars thereof.

     The Trustee shall not be bound to recognize any Person as a Securityholder
unless and until such Person's title to the Securities held by it is proved in
the manner in this Article Eight provided.

     The record of any Securityholders' meeting shall be proved in the manner
provided in Section 9.06.

     The Trustee may accept such other proof or require such additional proof of
any matter referred to in this Section 8.02 as it shall deem reasonable.

     SECTION 8.03.  Who May be Deemed Owners of Securities. Prior to due
                    --------------------------------------
presentment for transfer of any Security, the Company, the Trustee and any agent
of the Company or the Trustee may deem and treat the Person in whose name such
Security shall be registered upon the Register of Securities of the series of
which such Security is a part 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 interest, subject to the provisions of this Indenture,
on such Security and for all other purposes; and neither the Company nor the
Trustee nor any agent of the Company or the Trustee shall be affected by any
notice to the contrary.  All such payments so made to any such Holder for the
time being, or upon such Holder's order, shall be valid, and, to the extent of
the sum or sums so paid, effectual to satisfy and discharge the liability of
moneys payable upon any

                                       58
<PAGE>

such Security. The Company, the Trustee and any agent of the Company or the
Trustee may treat the Holder of any Unregistered Security and the Holder of any
Coupon as the absolute owner of such Unregistered Security or Coupon (whether or
not such Unregistered Security or Coupon shall be overdue) for the purpose of
receiving payment thereof or on account thereof and for all other purposes and
neither the Company, the Trustee, nor any agent of the Company or the Trustee
shall be affected by any notice to the contrary. All such payments so made to
any such person, or upon his order, shall be valid, and, to the extent of the
sum or sums so paid, effectual to satisfy and discharge the liability for moneys
payable upon any such Unregistered Security or Coupon.

     If the Securities of any series are issued in the form of one or more
Registered Global Securities, the Depository therefor may grant proxies to
Persons having a beneficial ownership in such Registered Global Security or
Securities for purposes of voting or otherwise responding to any request for
consent, waiver or other action which the Holder of such Registered Security is
entitled to grant or take under this Indenture and the Trustee shall accept such
proxies for the purposes granted; provided that neither the Trustee nor the
Company shall have any obligation with respect to the grant of or solicitation
by the Depository of such proxies.

     SECTION 8.04.  Securities Owned by the Company or Controlled or Controlling
                   -------------------------------------------------------------
Persons Disregarded for Certain Purposes.  In determining whether the Holders of
----------------------------------------
the requisite principal amount of Securities have concurred in any demand,
direction, request, notice, vote, consent, waiver or other action under this
Indenture, Securities which are owned by the Company or any other obligor on the
Securities or by any Person directly or indirectly controlling or controlled by
or under direct or indirect common control with the Company or any other obligor
on the Securities shall be disregarded and deemed not to be Outstanding for the
purpose of any such determination, provided that for the purposes of determining
whether the Trustee shall be protected in relying on any such demand, direction,
request, notice, vote, consent, waiver or other action, only Securities which a
Responsible Officer of the Trustee assigned to its principal office knows are so
owned shall be so disregarded.  Securities so owned which have been pledged in
good faith may be regarded as Outstanding for the purposes of this Section 8.04,
if the pledgee shall establish to the satisfaction of the Trustee the pledgee's
right to vote such Securities and that the pledgee is not a Person directly or
indirectly controlling or controlled by or under direct or indirect common
control with the Company or any such other obligor.

     Upon request of the Trustee, the Company shall furnish to the Trustee
promptly an Officer's Certificate listing and identifying all Securities, if
any, known by the Company to be owned or held by or for the account of the
Company or any other obligor on the Securities or by any Person directly or
indirectly controlling or controlled by or under direct or indirect common
control with the Company or any other obligor on the Securities; and, subject to
the provisions of Section 7.01, 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 8.05.  Instruments Executed by Securityholders Bind Future Holders.
                    -----------------------------------------------------------
At any time prior to (but not after) the evidencing to the Trustee, as provided
in Section 8.01, of the taking of any action by the Holders of the percentage in
principal amount of the Securities specified in this Indenture in connection
with such action, any Holder of a Security which is shown by the evidence to be
included in the Securities the Holders of which have consented to

                                       59
<PAGE>

such action may, by filing written notice with the Trustee at its principal
office and upon proof of holding as provided in Section 8.02, revoke such action
so far as concerns such Security. Except as aforesaid any such action taken by
the Holder of any Security and any direction, demand, request, notice, waiver,
consent, vote or other action of the Holder of any Security which by any
provisions of this Indenture is required or permitted to be given shall be
conclusive and binding upon such Holder and upon all future Holders and owners
of such Security, and of any Security issued in lieu thereof, irrespective of
whether any notation in regard thereto is made upon such Security. Any action
taken by the Holders of the percentage in principal amount of the Securities of
any or all series specified in this Indenture in connection with such action
shall be conclusively binding upon the Company, the Trustee and the Holders of
all of the Securities of such series subject, however, to the provisions of
Section 7.01.

advisable for any meeting of Securityholders, in regard to proof of the holding
of Securities and of the appointment of proxies, and in regard to the
appointment and duties of inspectors of votes, the submission and examination of
proxies, certificates and other evidence of the right to vote, and such other
matters concerning the conduct of the meeting as it shall think fit.  Except as
otherwise permitted or required by any such regulations, the holding of
Securities shall be proved in the manner specified in Section 8.02. and the
appointment of any proxy shall be proved in the manner specified in said Section
8.02; provided, however, that such regulations may provide that written
instruments appointing proxies regular on their face, may be presumed valid and
genuine without the proof hereinabove or in said Section 8.02 specified.

     The Trustee shall by an instrument in writing, appoint a temporary chairman
of the meeting, unless the meeting shall have been called by the Company or by
Securityholders as provided in Section 9.03, in which case the Company or the
Securityholders calling the meeting, as the case may be, shall in like manner
appoint a temporary chairman.  A permanent chairman and a permanent secretary of
the meeting shall be elected by majority vote of the meeting.

     Subject to the provisions of Section 8.04, at any meeting each
Securityholder or proxy shall be entitled to one vote for each $1,000 (or [Euro]
1,000) principal amount (in the case of Original Issue Discount Securities, such
principal amount shall be equal to such portion of the principal amount as may
be specified in the terms of such series) of Securities held or represented by
such Holder; provided, however, that no vote shall be cast or counted at any
meeting in respect of any Security challenged as not Outstanding and ruled by
the chairman of the meeting to be not Outstanding.  The chairman of the meeting
shall have no right to vote other than by virtue of Securities held by such
Person or instruments in writing as aforesaid duly designating such Person as
the Person to vote on behalf of other Securityholders.  Any meeting of
Securityholders duly called pursuant to the provisions of Section 9.02 or 9.03
may be adjourned from time to time, and the meeting may be held so adjourned
without further notice.

     At any meeting of Securityholders, the presence of Persons holding or
representing Securities in principal amount sufficient to take action on the
business for the transaction of which such meeting was called shall constitute a
quorum, but, if less than a quorum is present,

                                       61
<PAGE>

the Persons holding or representing a majority in principal amount of the
Securities represented at the meeting may adjourn such meeting with the same
effect for all intents and purposes, as though a quorum had been present.

     SECTION 9.06.  Manner of Voting at Meetings and Record to be Kept. The vote
                    --------------------------------------------------
upon any resolution submitted to any meeting of Securityholders shall be by
written ballots on which shall be subscribed the signatures of the Holders of
Securities or of their representatives by proxy and the principal amount or
principal amounts of the Securities held or represented by them.  The permanent
chairman of the meeting shall appoint two inspectors of votes who shall count
all votes cast at the meeting for or against any resolution and who shall make
and file with the secretary of the meeting their verified written reports in
duplicate of all votes cast at the meeting.  A record in duplicate of the
proceedings of each meeting of Securityholders shall be prepared by the
secretary of the meeting and there shall be attached to said record the original
reports of the inspectors of votes on any vote by ballot taken thereat and
affidavits by one or more Persons having knowledge of the facts setting forth a
copy of the notice of the meeting and showing that said notice was mailed as
provided in Section 9.02.  The record shall show the principal amount or
principal amounts of the Securities voting in favor of or against any
resolution.  The record shall be signed and verified by the affidavits of the
permanent chairman and secretary of the meeting and one copy thereof shall be
delivered to the Company and the other to the Trustee to be preserved by the
Trustee.

     Any record so signed and verified shall be conclusive evidence of the
matters therein stated.

     SECTION 9.07.  Exercise of Rights of Trustee and Securityholders Not to be
                    -----------------------------------------------------------
Hindered or Delayed.  Nothing in this Article Nine contained shall be deemed or
-------------------
construed to authorize or permit, by reason of any call of a meeting of
Securityholders or any rights expressly or impliedly conferred hereunder to make
such call, any hindrances or delay in the exercise of any right or rights
conferred upon or reserved to the Trustee or to the Securityholders under any of
the provisions of this Indenture or of the Securities.

Into Without Consent of Securityholders. Without the consent of the Holders of
---------------------------------------
any Securities, the Company and the Trustee may from time to time and at any
time enter into an indenture or indentures supplemental hereto (which shall
comply with the provisions of the Trust Indenture Act as then in effect) for one
or more of the following purposes:

     (a) to convey, transfer, assign, mortgage or pledge to the Trustee as
security for the Securities of one or more series any property or assets;

     (b) if deemed appropriate by the Company or required by law, to evidence
the succession of another Company to the Company or successive successions and
the assumption by the successor Company of the covenants, agreements and
obligations of the Company pursuant to Article Four hereof;

                                       62
<PAGE>

     (c) to add to the covenants of the Company such further covenants,
restrictions or conditions as its Board of Directors and the Trustee shall
consider to be for the protection of the Holders of all or any series of
Securities or Coupons (and if such covenants, restrictions or conditions are to
be for the benefit of less than all series of Securities, stating that such
covenants, restrictions or conditions are expressly being included solely for
the benefit of such series), and to make the occurrence, or the occurrence and
continuance, of a default in any such additional covenants, restrictions or
conditions an Event of Default permitting the enforcement of all or any of the
several remedies provided in this Indenture as herein set forth; provided,
however, that in respect to any such additional covenant, restriction or
condition 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 default or may limit the remedies available to the Trustee upon such
default;

     (d) to add or change any of the provisions of this Indenture to such extent
as shall be necessary to facilitate the issuance of Securities in (i) global
form or (ii) bearer form, registerable or not registerable as to principal or
principal and interest, and with or without coupons;

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

     (f) to establish the form or terms of Securities of any series or the
Coupons appertaining to such Securities as permitted by Sections 2.01 and 2.03;

     (g) to appoint, at the request of the Trustee, a successor Trustee for a
particular series of Securities to act as such pursuant to the provisions of
this Indenture and to add to or change the provisions of this Indenture to such
extent as shall be necessary to facilitate the performance of the duties of such
trustee; and

     (h) to cure any ambiguity or to correct or supplement any provisions
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 such other provisions in regard to matters or questions
arising under this Indenture or any Supplemental Indenture which shall not
adversely affect the interests of the Holders of the Securities or Coupons.

     SECTION 10.02.  Modification of Indenture with Consent of Holders of
                     ----------------------------------------------------
Securities.  With the consent (evidenced as provided in Section 8.01) of the
----------
Holders of not less than a majority in principal amount of the Securities of all
series at the time Outstanding (determined as provided in Section 8.04) affected
by such Supplemental Indenture (voting as one class), the Company and the
Trustee may from time to time and at any time enter into an indenture or
indentures supplemental hereto (which shall comply with the provisions of the
Trust Indenture Act as then in effect) 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 or the Coupons
appertaining to such Securities; provided, however, that no such Supplemental
Indenture shall, without the consent of the Holders of each Outstanding Security
affect thereby:

                                       63
<PAGE>

     (a) change the Stated Maturity of the principal of, or any installment of
principal of or interest on, any Security, or reduce the principal amount
thereof or the rate of interest thereon or any premium payable upon the
redemption thereof, or reduce the amount of the principal of an Original Issue
Discount Security or any other Security which would be due and payable upon a
declaration of acceleration of the Stated Maturity thereof pursuant to Section
6.01, or change any place of payment where, or the coin or currency in which,
any Security or any premium or interest thereon is payable, or impair the right
to institute suit for the enforcement of any such payment on or after the Stated
Maturity thereof (or, in the case of redemption, on or after the date fixed for
redemption), or modify the provisions of this Indenture with respect to this
subordination of the Securities in a manner adverse to the Holders, or

     (b) Reduce the percentage in principal amount of the Outstanding Securities
the consent of the Holders of which is required for any such Supplemental
Indenture, or the consent of the Holders of which is required for any waiver (of
compliance with certain provisions of this Indenture or certain defaults
hereunder and their consequences) provided for in this Indenture or

     (c) Change the time of payment or reduce the amount of any minimum sinking
account or fund payment or

     (d) Modify any of the provisions of this Section 10.02, except to increase
any such percentage or to provide that certain other provisions of this
Indenture cannot be modified or waived without the consent of the Holder of each
Security affected thereby.

     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, or of Coupons appertaining to
such Securities, 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 or of the Coupons appertaining to such Securities.

     Upon the request of the Company, 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 a Company Order) certified by the
secretary or an assistant secretary of the Company 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 8.01, the Trustee shall join with the
Company 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 Company and the Trustee of any
supplemental indenture pursuant to the provisions to this Section, the Trustee
shall give notice thereof (i) to the

                                       64
<PAGE>

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, (ii) if any
Unregistered Securities of a series affected thereby are then Outstanding, to
the Holders thereof who have filed their names and addresses with the Trustee
pursuant to Section 313(c)(2) of the Trust Indenture Act, by mailing a notice
thereof by first-class mail to such Holders at such addresses as were so
furnished to the Trustee and (iii) if any Unregistered Securities of a series
affected thereby are then Outstanding, to all Holders thereof, by publication of
a notice thereof at least once in an Authorized Newspaper in the Borough of
Manhattan, The City of New York and at least once in an Authorized Newspaper in
London (and, if required by Section 4.09, at least once in an Authorized
Newspaper in Luxembourg), and in each case such notice shall set forth in
general terms the substance of such supplemental indenture. Any failure of the
Company 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 10.03.  Effect of Supplemental Indentures.  Upon the execution of
                     ---------------------------------
any Supplemental Indenture pursuant to the provisions of this Article Ten, 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 the Trustee, the Company and the Holders
of Securities 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.

     The Trustee shall be entitled to receive, and subject to the provisions of
Section 7.01 shall be entitled to rely upon, an Opinion of Counsel as conclusive
evidence that any such Supplemental Indenture complies with the provisions of
this Article Ten and that the Securities affected by the Supplemental Indenture,
when such Securities are authenticated and delivered by the Trustee and executed
and issued by the Company in the manner and subject to any conditions specified
in such Opinion of Counsel, will be valid and binding obligations of the
Company, except as any rights thereunder may be limited by bankruptcy,
insolvency and other similar laws affecting the enforcement of creditors' rights
generally and by general equity principles.

     SECTION 10.04.  Securities May Bear Notation of Changes by Supplemental
                    --------------------------------------------------------
Indentures.  Securities authenticated and delivered after the execution of any
----------
Supplemental Indenture pursuant to the provisions of this Article Ten, or after
any action taken at a Securityholders' meeting pursuant to Article Nine, may
bear a notation in form approved by the Trustee as to any matter provided for in
such Supplemental Indenture or as to any action taken at any such meeting.  If
the Company or the Trustee shall so determine, new Securities so modified as to
conform, in the opinion of the Trustee and the Company, to any modification of
this Indenture contained in any such Supplemental Indenture may be prepared by
the Company, authenticated by the Trustee and delivered in exchange for the
Securities then Outstanding.

provided, that the rights of Holders of the Securities and Coupons to receive
amounts in respect of principal of and interest on the Securities and Coupons

     deposited or caused to be irrevocably deposited with the Trustee as trust
     funds in trust, specifically pledged as security for, and dedicated solely

     Indenture and the Securities of such series;

          (b) such deposit will not result in a breach or violation of, or

     Securities of such series and Coupons appertaining thereto 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; and

          (d) the Company 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

4.02 and unless otherwise provided for in the Board Resolution, Officer's
Certificate or Indenture supplemental hereto establishing such series of
Securities, from all covenants and other obligations referred to in Section
2.03(18) or 2.03(20) with respect to such series of Securities, and any Coupons
appertaining thereto, 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 Company 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 6.01, but the remainder of this
Indenture and such Securities and Coupons shall be unaffected thereby.  The
following shall be the conditions to application of this subsection C of this
Section 11.01:

          (a) The Company 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

     coupons appertaining thereto, (i) cash in an amount, or (ii) in the case of
     any series of Securities the payments on which may only be made in United
     States Dollars, 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

                                       68

     Coupons appertaining thereof 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;

          (b) 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;

          (c) Such covenant defeasance shall not cause the Trustee to have a
     conflicting interest as defined in Section 7.08 and for purposes of the
     Trust Indenture Act with respect to any securities of the Company;

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

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

          (f) The Company shall have delivered to the Trustee an Officer's
     Certificate and Opinion of Counsel to the effect that the Holders of the
     Securities of such series and Coupons appertaining thereto 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; and

          (g) The Company 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 11.02.  Application by Trustee of Funds Deposited for Payment of
                     --------------------------------------------------------
Securities.  Subject to Section 11.04, all moneys deposited with the Trustee
----------
(for other trustee) pursuant to Section 11.01 shall be held in trust and applied
by it to the payment, either directly or through any Paying Agent (including the
Company acting as its own Paying Agent), to the Holders of the particular
Securities of such series and of Coupons appertaining thereto 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

     SECTION 13.08.  Securities in a Foreign Currency or in ECU.  Unless
                    -------------------------------------------
otherwise specified in an Officer's Certificate delivered pursuant to Section
2.03 of this Indenture with respect to a particular series of Securities,
whenever for purposes of this Indenture any action may be taken by the Holders
of a specified percentage in aggregate principal amount of Securities of all
series or all series affected by a particular action at the time Outstanding
and, at such time, there are Outstanding Securities of any series which are
denominated in a coin or currency other than United States Dollars (including
ECUs), then the principal amount of Securities of such series which shall be
deemed to be Outstanding for the purpose of taking such action shall be that
amount of United States Dollars that could be obtained for such amount at the
Market Exchange Rate.  For purposes of this Section 13.08, Market Exchange Rate

cable transfers of that currency as published by the Federal Reserve Bank of New
York; provided, in the case of ECUs, Market Exchange Rate shall mean the rate of
exchange determined by the Commission of the European Communities (or any
successor thereto) as published in the Official Journal of the European
Communities (such publication or any successor publication, the "Journal").  If
such Market Exchange Rate is not available for any reason with respect to such
currency, the Trustee shall use, in its sole discretion and without liability on
its part, such quotation of the Federal Reserve Bank of New York or, in the case
of ECUs, the rate of exchange as published in the Journal, as of the most recent
available date, or quotations or, in the case of ECUs, rates of exchange from
one or more major banks in The City of New York or in the country of issue of
the currency in question, which for purposes of the ECU shall be Brussels,
Belgium, or such other quotations or, in the case of ECU, rates of exchange as
the Trustee shall deem appropriate.  The provisions of this paragraph shall
apply in determining the equivalent principal amount in respect of Securities of
a series denominated in a currency other than Dollars in connection with any
action taken by Holders of Securities pursuant to the terms of this Indenture.

                                       73

     All decisions and determinations of the Trustee regarding the Market
Exchange Rate or any alternative determination provided for in the preceding
paragraph shall be in its sole discretion and shall, in the absence of manifest
error, be conclusive to the extent permitted by law for all purposes and
irrevocably binding upon the Company and all Holders.

     SECTION 13.09.  Judgment Currency.  The Company agrees, to the fullest
                     -----------------
extent that it may effectively do so under applicable law, that (a) if for the
purpose of obtaining judgment in any court it is necessary to convert the sum
due in respect of the principal of or interest on the Securities of any series
(the "Required Currency"), into a currency in which a judgment will be rendered
(the "Judgment Currency"), the rate of exchange used shall be the rate at which
in accordance with normal banking procedures the Trustee could purchase in The
City of New York the Required Currency with the Judgment Currency on the day on
which final unappealable judgment is entered, unless such day is not a New York
Banking Day, then, to the extent permitted by applicable law, the rate of
exchange used shall be the rate at which in accordance with normal banking
procedures the Trustee could purchase in The City of New York the Required
Currency with the Judgment Currency on the New York Banking Day preceding the
day on which final unappealable judgment is entered and (b) its obligations
under this Indenture to make payments in the Required Currency (i) shall not be
discharged or satisfied by any tender, or any recovery pursuant to any judgment
(whether or not entered in accordance with subsection (a)), in any currency
other than the Required Currency, except to the extent that such tender or
recovery shall result in the actual receipt, by the payee, of the full amount of
the Required Currency expressed to be payable in respect of such payments, (ii)
shall be enforceable as an alternative or additional cause of action for the
purpose of recovering in the Required Currency the amount, if any, by which such
actual receipt shall fall short of the full amount of the Required Currency so
expressed to be payable and (iii) shall not be affected by judgment being
obtained for any other sum due under this Indenture.  For purposes of the
foregoing, "New York Banking Day" means any day except a Saturday, Sunday or a
legal holiday in The City of New York or a day on which banking institutions in
The City of New York are authorized or required by law or executive order to
close.
