acceptable to the Trustee as may be specified from time to time by an Issuer
Order, (iii) the maturity date or dates, original issue date or dates, interest
rate or rates and any other terms of Securities of such series (including
Redemption Notice Periods) shall be determined by an Issuer Order or pursuant to
such procedures and (iv) if provided for in such procedures, such Issuer Order
may authorize authentication and delivery pursuant to oral or electronic
instructions from the Issuer or its duly authorized agent or agents, which oral
instructions shall be promptly confirmed in writing.

      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 Issuer or if the
Trustee in good faith by its board of directors or board of trustees, executive
committee, or a trust committee of directors or trustees or Responsible Officers
shall reasonably determine that such action would expose the Trustee to personal
liability to existing Holders or would affect the Trustee's own rights, duties
or immunities under the Securities, this Indenture or otherwise.

      If the Issuer shall establish pursuant to Section 2.03 that the Securities
of a series are to be issued in the form of one or more Registered Global
Securities, then the Issuer shall execute and the Trustee shall, in accordance
with this Section and the Issuer Order with respect to such series, authenticate
and deliver one or more Registered Global Securities that (i) shall represent
and shall be denominated in an amount equal to the aggregate principal amount of
all of the Securities of such series issued and not yet cancelled, (ii) shall be
registered in the

                                                                            ----

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

      Each Depositary designated pursuant to Section 2.03 must, at the time of
its designation and at all times while it serves as Depositary, be a clearing
agency registered under the Securities Exchange Act of 1934 and any other
applicable statute or regulation.

      SECTION 2.05. Execution of Securities. The Securities and, if applicable,
each Coupon appertaining thereto shall be signed on behalf of the Issuer by any
one of the following: the Chairman of the Board, the President, any Vice
President, the Chief Financial Officer, the Chief Legal Officer, the Treasurer,
any Assistant Treasurer, the Controller, any Assistant Controller or any other
person authorized by the Board of Directors to execute Securities or, if
applicable, Coupons, which Securities or Coupons may, but need not, be attested.
Such signatures may be the manual or facsimile signatures of the present or any
future such officers. Minor errors or defects in any such reproduction of any
such signature shall not affect the validity or enforceability of any Security
that has been duly authenticated and delivered by the Trustee.

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

      SECTION 2.06. 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

                                                                            PAGE
                                                                            ----

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
Issuer shall be conclusive evidence that the Security so authenticated has been
duly authenticated and delivered hereunder and that the Holder is entitled to
the benefits of this Indenture.

      SECTION 2.07. Denomination and Date of Securities; Payments of Interest.
The Securities of each series shall be issuable as Registered Securities or
Unregistered Securities in denominations established as contemplated by Section
2.03 or, with respect to the Registered Securities of any series, if not so
established, in denominations of $1,000 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 any integral
multiple thereof. The Securities of each series shall be numbered, lettered or
otherwise distinguished in such manner or in accordance with such plan as the
officers of the Issuer executing the same may determine with the approval of the
Trustee, as evidenced by the execution and authentication thereof.

      Each Registered Security shall be dated the date of its authentication.
Each Unregistered Security shall be dated as provided in the resolution or
resolutions of the Board of Directors of the Issuer referred to in Section 2.03.
The Securities of each series shall bear interest, if any, from the date, and
such interest shall be payable on the dates, established as contemplated by
Section 2.03.

      The Person in whose name any Registered Security of any series is
registered at the close of business on any record date applicable to a
particular series with respect to any interest payment date for such series
shall be entitled to receive the interest, if any, payable on such interest
payment date notwithstanding any transfer or exchange of such Registered
Security subsequent to the record date and prior to such interest payment date,
except if and to the extent the Issuer shall default in the payment of the
interest due on such interest payment date for such series, in which case such
defaulted interest shall be paid to the Persons in whose names Outstanding
Registered Securities for such series are registered at the close of business on
a subsequent record date (which shall be not less than five Business Days prior
to the date of payment of such defaulted interest) established by notice given
by mail by or on behalf of the Issuer to the Holders of Registered Securities
not less than 10 days preceding such subsequent record date. The term "record
date" as used with respect to any interest payment date (except a date for
payment of defaulted interest) for the Securities of any series shall mean the
date specified as such in the terms of the Registered Securities of such series
established as contemplated by Section 2.03, or, if no such date is so
established, if
<PAGE>

                                                                            PAGE
                                                                            ----

such interest payment date is the first day of a calendar month, the fifteenth
day of the next preceding calendar month or, if such interest payment date is
the fifteenth day of a calendar month, the first day of such calendar month,
whether or not such record date is a Business Day.

      SECTION 2.08. Registration, Transfer and Exchange. The Issuer will keep at
each office or agency to be maintained for the purpose as provided in Section
3.02 for each series of Securities a register or registers in which, subject to
such reasonable regulations as it may prescribe, it will provide for the
registration of Registered Securities of such series and the registration of
transfer of Registered Securities of such series. Such register shall be in
written form in the English language or in any other form capable of being
converted into such form within a reasonable time. At all reasonable times such
register or registers shall be open for inspection by the Trustee.

      Upon due presentation for registration of transfer of any Registered
Security of any series at any such office or agency to be maintained for the
purpose as provided in Section 3.02, the Issuer shall execute and the Trustee
shall authenticate and deliver in the name of the transferee or transferees a
new Registered Security or Registered Securities of the same series, maturity
date, interest rate and original issue date in authorized denominations for a
like aggregate principal amount.

      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
having authorized denominations and an equal aggregate principal amount, upon
surrender of such Registered Securities to be exchanged at the agency of the
Issuer that shall be maintained for such purpose in accordance with Section 3.02
and upon payment, if the Issuer 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 specified 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 having authorized
denominations and an equal aggregate principal amount, upon surrender of such
Unregistered Securities to be exchanged at the agency of the Issuer that shall
be maintained for such purpose in accordance with Section 3.02, 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 Issuer shall so require, of the charges
<PAGE>

                                                                            PAGE
                                                                            ----

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
specified pursuant to Section 2.03, such Unregistered Securities may be
exchanged for Unregistered Securities of such series having authorized
denominations and an equal aggregate principal amount, upon surrender of such
Unregistered Securities to be exchanged at the agency of the Issuer that shall
be maintained for such purpose in accordance with Section 3.02 or as specified
pursuant to Section 2.03, 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 Issuer shall so require, of the
charges hereinafter provided. Unless otherwise specified pursuant to Section
2.03, Registered Securities of any series may not be exchanged for Unregistered
Securities of such series. Whenever any Securities are so surrendered for
exchange, the Issuer shall execute, and the Trustee shall authenticate and
deliver, the Securities which the Holder making the exchange is entitled to
receive. All Securities and Coupons surrendered upon any exchange or transfer
provided for in this Indenture shall be promptly cancelled and disposed of by
the Trustee and the Trustee will deliver a certificate of disposition thereof to
the Issuer.

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

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

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

      Notwithstanding any other provision of this Section 2.08, unless and until
it is exchanged in whole or in part for Securities in definitive registered
form, a
<PAGE>

                                                                            PAGE
                                                                            ----

Registered Global Security representing all or a portion of the Securities of a
series may not be transferred except as a whole by the Depositary for such
series to a nominee of such Depositary or by a nominee of such Depositary to
such Depositary or another nominee of such Depositary or by such Depositary or
any such nominee to a successor Depositary for such series or a nominee of such
successor Depositary.

      If at any time the Depositary for any Registered Securities of a series
represented by one or more Registered Global Securities notifies the Issuer that
it is unwilling or unable to continue as Depositary for such Registered
Securities or if at any time the Depositary for such Registered Securities shall
no longer be eligible under Section 2.04, the Issuer shall appoint a successor
Depositary eligible under Section 2.04 with respect to such Registered
Securities. If a successor Depositary eligible under Section 2.04 for such
Registered Securities is not appointed by the Issuer within 90 days after the
Issuer receives such notice or becomes aware of such ineligibility, the Issuer's
election pursuant to Section 2.03 that such Registered Securities be represented
by one or more Registered Global Securities shall no longer be effective and the
Issuer will execute, and the Trustee, upon receipt of an Officer's Certificate
for the authentication and delivery of definitive Securities of such series,
will authenticate and deliver, Securities of such series in definitive
registered form without coupons, in any authorized denominations, in an
aggregate principal amount equal to the principal amount of the Registered
Global Security or Securities representing such Registered Securities in
exchange for such Registered Global Security or Securities.

      The Issuer may at any time and in its sole discretion determine that the
Registered Securities of any series issued in the form of one or more Registered
Global Securities shall no longer be represented by a Registered Global Security
or Securities. In such event the Issuer will execute, and the Trustee, upon
receipt of an Officer's Certificate for the authentication and delivery of
definitive Securities of such series, will authenticate and deliver, Securities
of such series in definitive registered form without coupons, in any authorized
denominations, in an aggregate principal amount equal to the principal amount of
the Registered Global Security or Securities representing such Registered
Securities, in exchange for such Registered Global Security or Securities.

      If specified by the Issuer pursuant to Section 2.03 with respect to
Securities represented by a Registered Global Security, the Depositary for such
Registered Global Security may surrender such Registered Global Security in
exchange in whole or in part for Securities of the same series in definitive
registered form on such terms as are acceptable to the Issuer and such
Depositary. Thereupon, the Issuer shall execute, and the Trustee shall
authenticate and deliver, without service charge,

                                                                            PAGE
                                                                            ----

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

      (b) 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 (a) above.

      Upon the exchange of a Registered Global Security for Securities in
definitive registered form without coupons, in authorized denominations, such
Registered Global Security shall be cancelled by the Trustee or an agent of the
Issuer or the Trustee. Securities in definitive registered form without coupons
issued in exchange for a Registered Global Security pursuant to this Section
2.08 shall be registered in such names and in such authorized denominations as
the Depositary for such Registered Global Security, pursuant to instructions
from its direct or indirect participants or otherwise, shall instruct the
Trustee or an agent of the Issuer or the Trustee. The Trustee or such agent
shall deliver such Securities to or as directed by the Persons in whose names
such Securities are so registered.

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

      Notwithstanding anything herein or in the terms of any series of
Securities to the contrary, none of the Issuer, the Trustee or any agent of the
Issuer or the Trustee (any of which, other than the Issuer, shall rely on an
Officer's Certificate and an Opinion of Counsel) 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 Issuer (such as, for
example, the inability of the Issuer 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.

      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 become mutilated, defaced or be destroyed, lost or stolen, the
Issuer in its discretion may execute, and upon the written request of any
officer of the Issuer, the Trustee shall authenticate and deliver a new Security
of the same series, maturity date, interest rate and original issue date,
bearing a number or other distinguishing symbol not contemporaneously
outstanding, in exchange and substitution for the mutilated or defaced Security,
or in lieu of and in substitution for the Security so destroyed, lost or stolen
with Coupons corresponding to the Coupons appertaining to the Securities so
mutilated, defaced, destroyed, lost or stolen, or in exchange or substitution
<PAGE>

                                                                            PAGE
                                                                            ----

for the Security to which such mutilated, defaced, destroyed, 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 Issuer and to
the Trustee and any agent of the Issuer or the Trustee such security or
indemnity as may be required by them to indemnify and defend and to save each of
them harmless and, in every case of destruction, loss or theft, evidence to
their satisfaction of the destruction, loss or theft of such Security 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 Issuer may
require the payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in relation thereto and any other expenses (including
the fees and expenses of the Trustee or its agent) connected therewith. In case
any Security 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 Issuer 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 Issuer and to the Trustee and
any agent of the Issuer or the Trustee such security or indemnity as any of them
may require to save each of them harmless, and, in every case of destruction,
loss or theft, the applicant shall also furnish to the Issuer and the Trustee
and any agent of the Issuer or the Trustee evidence to their satisfaction of the
destruction, loss or theft of such Security or Coupon 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 Issuer, 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 statute existing or hereafter
enacted to the contrary with respect to the replacement or payment of negotiable
instruments or other securities without their surrender.

      SECTION 2.10. Cancellation of Securities; Disposition Thereof. All
Securities and Coupons surrendered for payment, redemption, registration of
transfer or exchange, or for credit against any payment in respect of a sinking
or analogous fund, if surrendered to the Issuer or any agent of the Issuer or
the Trustee or any agent of the Trustee, shall be delivered to the Trustee or
its agent for cancellation or, if surrendered to the Trustee, shall be cancelled
by it; 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 or
its agent shall dispose of cancelled Securities and Coupons held by it and
deliver promptly a certificate of disposition to the Issuer. If the Issuer or
its agent shall acquire any of the Securities or Coupons, such acquisition shall
not operate as a redemption or satisfaction of the indebtedness represented by
such Securities or Coupons unless and until the same are delivered to the
Trustee or its agent for cancellation.

      SECTION 2.11. Temporary Securities. Pending the preparation of definitive
Securities for any series, the Issuer may execute and the Trustee shall
authenticate and deliver temporary Securities for such series (printed,
lithographed, typewritten or otherwise reproduced, in each case in form
satisfactory to the Trustee). Temporary Securities of any series shall be
issuable as Registered Securities without coupons, 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 omissions, insertions and variations as may be appropriate for temporary
Securities, all as may be determined by the Issuer with the concurrence of the
Trustee as evidenced by the execution and authentication thereof. Temporary
Securities may contain such references to any provisions of this Indenture as
may be appropriate. Every temporary Security shall be executed by the Issuer and
be authenticated by the Trustee upon the same conditions and in substantially
the same manner, and with like effect, as the definitive Securities. Without
unreasonable delay the Issuer shall execute and shall furnish definitive
Securities of such series and thereupon temporary Registered Securities of such
series may be surrendered in exchange therefor without charge at each office or
agency to be maintained by the Issuer for that purpose pursuant to Section 3.02
and, in the case of Unregistered Securities, at any agency maintained by the
Issuer for such purpose as specified pursuant to Section 2.03, and the Trustee
shall authenticate and deliver in exchange for such temporary Securities of such
series an equal aggregate principal amount of definitive Securities of the same
series having authorized denominations and, in the case of Unregistered
Securities, having attached thereto any appropriate Coupons. Until so exchanged,
the temporary Securities of any series shall be entitled to the same benefits
under this Indenture as definitive Securities of such series, unless otherwise
established pursuant to Section 2.03. 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).

                             COVENANTS OF THE ISSUER

      SECTION 3.01. Payment of Principal and Interest. The Issuer covenants and
agrees for the benefit of each series of Securities that it will duly and
punctually pay or cause to be paid the principal of, and interest on, each of
the Securities of such series (together with any additional amounts payable
pursuant to the terms of such Securities) at the place or places, at the
respective times and in the manner provided in such Securities and in the
Coupons, if any, appertaining thereto and in this Indenture. 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 on Registered Securities (together with any additional amounts
payable pursuant to the terms of such Securities) shall be payable only to or
upon the written order of the Holders thereof and, at the option of the Issuer,
may be paid by wire transfer or by mailing checks for such interest payable to
or upon the written order of such Holders at their last addresses as they appear
on the registry books of the Issuer.

      SECTION 3.02. Offices for Payments, etc. So long as any Securities are
authorized for issuance pursuant to this Indenture or are outstanding hereunder,
the Issuer will maintain in the Borough of Manhattan, The City of New York, an
office or agency where the Securities of each series may be presented for
payment, where the Securities of each series may be presented for exchange as is

provided in this Indenture, where notices and demands to or upon the Issuer in
respect of the Securities of each series, the Coupons appertaining thereto or
this Indenture may be served, and, if applicable, pursuant to Section 2.03 where
the Securities of each series may be presented for registration of transfer as
in this Indenture provided.

      The Issuer will maintain one or more offices or agencies in a city or
cities located outside the United States as may be required to be maintained
under the rules of any stock exchange on which the Securities of such series are
listed. No payment on any Unregistered Security or Coupon will be made upon
presentation of such Unregistered Security or Coupon at an agency of the Issuer
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 Issuer. Notwithstanding the foregoing,
payments in Dollars of Unregistered Securities of any series and Coupons
appertaining thereto which are payable in Dollars may be made at an agency of
the Issuer maintained in the Borough of Manhattan, The City of New York if such
payment in Dollars at each agency maintained by the Issuer outside the United
States for payment on such Unregistered Securities is illegal or effectively
precluded by exchange controls or other similar restrictions.

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

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

      SECTION 3.03. Appointment to Fill a Vacancy in Office of Trustee. The
Issuer, whenever necessary to avoid or fill a vacancy in the office of Trustee,
will appoint, in the manner provided in Section 6.10, a Trustee, so that there
shall at all times be a Trustee with respect to each series of Securities
hereunder.

      SECTION 3.04. Paying Agents. Whenever the Issuer shall appoint a paying
agent other than the Trustee with respect to the Securities of any series, it
will cause such paying agent to execute and deliver to the Trustee an instrument
in which such agent shall agree with the Trustee, subject to the provisions of
this Section,

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

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

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

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

      If the Issuer shall act as its own paying agent with respect to the
Securities of any series, it will, on or before each due date of the principal
of 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 Issuer will promptly notify the Trustee of any failure to
take such action.

      Anything in this Section to the contrary notwithstanding, but subject to
Section 10.01, the Issuer may at any time, for the purpose of obtaining a
satisfaction and discharge with respect to one or more or all series of
Securities hereunder, or for any other reason, pay or cause to be paid to the
Trustee all sums held in trust for any such series by the Issuer or any paying
agent hereunder, as required by this Section, such sums to be held by the
Trustee upon the trusts herein contained.

      Anything in this Section to the contrary notwithstanding, the agreement to
hold sums in trust as provided in this Section is subject to the provisions of
Sections 10.03 and 10.04.

      SECTION 3.05. [INTENTIONALLY OMITTED].

      SECTION 3.06. [INTENTIONALLY OMITTED].

      SECTION 3.07. Existence. Subject to Article 9, the Issuer will do or cause
to be done all things necessary to preserve and keep in full force and effect
its existence and rights (charter and statutory); provided, however, that the
Issuer shall not be required to preserve any such right if the Issuer shall
determine that the preservation thereof is no longer desirable in the conduct of
the business of the Issuer and that the loss thereof is not disadvantageous in
any material respect to the Securityholders.

      SECTION 3.08. Maintenance of Properties. The Issuer will cause all
properties used or useful in the conduct of its business or the business of any
Significant Subsidiary 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 Issuer may be necessary in the conduct of
its business or the business of any Significant Subsidiary; provided, however,
that nothing in this Section shall prevent the Issuer from discontinuing the
operation or maintenance of any of such properties if such discontinuance is, in
the judgment of the Issuer, desirable in the conduct of its business or the
business of any Subsidiary and not disadvantageous in any material respect to
the Securityholders.

      SECTION 3.09. Payment of Taxes and Other Claims. The Issuer will pay or
discharge, or cause to be paid or discharged, before the same may become
delinquent, (i) all taxes, assessments and governmental charges levied or
imposed upon the Issuer or any Significant Subsidiary or upon the income,
profits or property of the Issuer or any Significant Subsidiary, (ii) all claims
for labor, materials and supplies which, if unpaid, might by law become a lien
or charge upon the property of the Issuer or any Significant Subsidiary and
(iii) all stamps and other duties, if any, which may be imposed by the United
States or any political subdivision thereof or therein in connection with the
issuance, transfer, exchange or conversion of any Securities or with respect to
this Indenture; provided, however, that, in the case of clauses (i) and (ii),
the Issuer shall not be required to pay or discharge or cause to be paid or
discharged any such tax, assessment, charge or claim (A) if the failure to do so
will not, in the aggregate,

have a material adverse impact on the Issuer, or (B) if the amount,
applicability or validity is being contested in good faith by appropriate
proceedings.

      SECTION 3.10. Stay, Extension and Usury Laws. The Issuer covenants (to the
extent that it may lawfully do so) that it shall not at any time insist upon,
plead, or in any manner whatsoever claim or take the benefit or advantage of,
any stay, extension or usury law or other law which would prohibit or forgive
the Issuer from paying all or any portion of the principal of, premium, if any,
or interest on the Securities as contemplated herein, wherever enacted, now or
at any time hereafter in force, or which may affect the covenants or the
performance of this Indenture and the Issuer (to the extent it may lawfully do
so) hereby expressly waives all benefit or advantage of any such law, and
covenants that it will not, by resort to any such law, hinder, delay or impede
the execution of any power herein granted to the Trustee, but will suffer and
permit the execution of every such power as though no such law had been enacted.

      SECTION 3.11. Compliance Certificate. The Issuer shall deliver to the
Trustee, within one hundred twenty (120) days after the end of each fiscal year
of the Issuer, a certificate signed by either the principal executive officer,
principal financial officer or principal accounting officer of the Issuer,
stating whether or not to the best knowledge of the signer thereof the Issuer is
in default in the performance and observance of any of the terms, provisions and
conditions of this Indenture (without regard to any period of grace or
requirement of notice provided hereunder) and, if the Issuer shall be in
default, specifying all such defaults and the nature and the status thereof of
which the signer may have knowledge.

      The Issuer will deliver to the Trustee, so long as any of the Securities
are Outstanding, forthwith upon becoming aware of (i) any default in the
performance or observance of any covenant, agreement or condition contained in
this Indenture that is, or after notice or passage of time or both would be, and
Event of Default, or (ii) any Event of Default, an Officer's Certificate
specifying with particularity such default or Event of Default and further
stating what action the Issuer has taken, is taking or proposes to take with
respect thereto.

      Any notice required to be given under this Section 3.11 shall be delivered
to a Responsible Officer of the Trustee at its Corporate Trust Office. In the
event that the payment of the Securities of any series is accelerated because of
an Event of Default, the Issuer shall promptly provide written notice to the
Trustee specifying the names and addresses of the holders of Senior Indebtedness
if the Trustee (and not the Issuer) is to provide holders of Senior Indebtedness
notice of such acceleration.

         SECURITYHOLDERS LISTS AND REPORTS BY THE ISSUER AND THE TRUSTEE

      SECTION 4.01. Issuer to Furnish Trustee Information as to Names and
Addresses of Securityholders. If and so long as the Trustee shall not be the
Security registrar for the Securities of any series, the Issuer and any other
obligor on the Securities will furnish or cause to be furnished to the Trustee a

addresses of the Holders of the Registered Securities of such series pursuant to
Section 312 of the Trust Indenture Act of 1939 (a) semi-annually not more than

such request as of a date not more than 15 days prior to the time such

      SECTION 4.02. Preservation and Disclosure of Securityholders Lists.

      (a) The Trustee shall preserve, in as current a form as is reasonably

Securities of each series contained in the most recent list furnished to it as
provided in Section 4.01 or maintained by the Trustee in its capacity as
Security registrar or co-registrar in respect of the Securities of any series,
if so acting. The Trustee may destroy any list furnished to it as provided in
Section 4.01 upon receipt of a new list so furnished.

      (b) The rights of Securityholders to communicate with other holders of
Securities of any series with respect to their rights under this Indenture or
under the Securities, and the corresponding rights and duties of the Trustee,
shall be as provided by the Trust Indenture Act.

      (c) Every Securityholder, by receiving and holding the same, agrees with
the Issuer and the Trustee that neither the Issuer nor the Trustee nor any agent
of either of them shall be held accountable by reason of any disclosure of
information as to names and addresses of holders of Securities made pursuant to
the Trust Indenture Act.

      SECTION 4.03. Reports by the Issuer. The Issuer covenants to file with the
Trustee, copies of the annual reports and of the information, documents, and
other reports that the Issuer may be required to file with the Commission

of the Trust Indenture Act of 1939, so long as any Securities are Outstanding
hereunder, and shall be dated as of a date convenient to the Trustee no more
than 60 days prior thereto. The Trustee shall also comply with Section 313(b)(2)

         REMEDIES OF THE TRUSTEE AND SECURITYHOLDERS ON EVENT OF DEFAULT

      SECTION 5.01. Event of Default Defined; Acceleration of Maturity; Waiver
of Default. Unless otherwise set forth in a supplemental indenture, "Event of
Default" with respect to Securities of any series wherever used herein, means
each one of the following events which shall have occurred and be continuing
(whatever the reason for such Event of Default and whether it shall be voluntary
or involuntary or be effected by operation of law or pursuant to any judgment,
decree or order of any court or any order, rule or regulation of any
administrative or governmental body):

      (a) default in the payment of any installment of interest upon any of the
Securities of such series as and when the same shall become due and payable, and
continuance of such default for a period of 30 days; or

      (b) default in the payment of all or any part of the principal on any of
the Securities of such series as and when the same shall become due and payable
either at maturity, upon any redemption, by declaration or otherwise; or

      (c) failure on the part of the Issuer duly to observe or perform any other
of the covenants or agreements on the part of the Issuer in the Securities of
such series (other than a covenant or warranty in respect of the Securities of
such series a default in the performance or breach of which is elsewhere in this
Section specifically dealt with) or in this Indenture contained for a period of
60 days after the date on which written notice specifying such failure, stating
that such notice is a "Notice of Default" hereunder and demanding that the
Issuer remedy the same, shall have been given by registered or certified mail,
return receipt requested, to the Issuer by the Trustee, or to the Issuer and the
Trustee by the holders of at least 25% in aggregate principal amount of the
Outstanding Securities of all series affected thereby; or

      (d) a court having jurisdiction in the premises shall enter a decree or
order for relief in respect of the Issuer in an involuntary case under any
applicable bankruptcy, insolvency or other similar law now or hereafter in
effect, or appointing a receiver, liquidator, assignee, custodian, trustee,
sequestrator (or similar official) of the Issuer or for any substantial part of
its property or ordering the winding up or liquidation of its affairs, and such
decree or order shall remain unstayed and in effect for a period of 90
consecutive days; or

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

      (f) any other Event of Default provided in the supplemental indenture
under which such series of Securities is issued or in the form of Security for
such series.

      If an Event of Default described in clauses (a), (b), (c) or (f) (only if
the Event of Default under clause (c) or (f), as the case may be, is with
respect to less than all series of Securities then Outstanding) occurs and is
continuing, then, and in each and every such case, except for any series of
Securities the principal of which shall have already become due and payable,
either the Trustee or the Holders of not less than 25% in aggregate principal
amount of the Securities of each such affected series then Outstanding hereunder
(voting as a single class) by notice in writing to the Issuer (and to the
Trustee if given by Securityholders), may declare the entire principal (or, if
the Securities of any such affected 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 all such affected 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. If an
Event of Default described in clause (c) or (f) (only if the Event of Default
under clause (c) or (f), as the case may be, is with respect to all series of
Securities then Outstanding), (d) or (e) occurs and is continuing, then and in
each and every such case, unless the principal of all the Securities shall have
already become due and payable, either the Trustee or the Holders of not less
than 25% in aggregate principal amount of all the Securities then Outstanding
hereunder (treated as one class), by notice in writing to the Issuer (and to the
Trustee if given by Securityholders), may declare the entire principal (or, if
any Securities are Original Issue Discount Securities, such portion of the
principal as may be specified in the terms thereof) of all the Securities then
Outstanding, and 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 (or, if the Securities are Original Issue
Discount Securities, such portion of the principal as may be specified in the
terms thereof) of the Securities of any series (or of all the Securities, as the
case may be) shall have been so declared due and payable, and before any
judgment or decree for the payment of the moneys due shall have been obtained or
entered as hereinafter provided, the Issuer shall pay or shall deposit with the
Trustee a sum sufficient to pay all matured installments of interest upon all
the Securities of each such series (or of all the Securities, as the case may
be) and the principal of any and all Securities of each such series (or of all
the Securities, as the case may be) which shall have become due otherwise than
by acceleration (with 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 such amount as shall be sufficient to cover reasonable
compensation to the Trustee and each predecessor Trustee, its agents, attorneys
and counsel, and all other reasonable expenses and liabilities incurred, and all
advances made, by the Trustee and each predecessor Trustee, and if any and all
Events of Default under the Indenture, other than the non-payment of the
principal of Securities which shall have become due by acceleration, shall have
been cured, waived or otherwise remedied as provided herein -- then and in every
such case the Holders of a majority in aggregate principal amount of all the
Securities of each such series or of all the Securities, in each case voting as
a single class, then Outstanding, by written notice to the Issuer and to the
Trustee, may waive all defaults with respect to each such series (or with
respect to all the Securities, as the case may be) and rescind and annul such
declaration and its consequences, but no such waiver or rescission and annulment
shall extend to or shall affect any subsequent default or shall impair any right
consequent thereon.

      For all purposes under this Indenture, if a portion of the principal of
any Original Issue Discount Securities shall have been accelerated and declared
due and payable pursuant to the provisions hereof, then, from and after such
declaration, unless such declaration has been rescinded and annulled, the
principal amount of such Original Issue Discount Securities shall be deemed, for
all purposes hereunder, to be such portion of the principal thereof as shall be
due and payable as a result of such acceleration, and payment of such portion of
the principal thereof as shall be due and payable as a result of such
acceleration, together with interest, if any, thereon and all other amounts
owing thereunder, shall constitute payment in full of such Original Issue
Discount Securities.

      SECTION 5.02. Collection of Indebtedness by Trustee; Trustee May Prove
Debt. The Issuer covenants that (a) in case default shall be made in the payment
of any installment of interest on any of the Securities of any series when such
interest shall have become due and payable, and such default shall have
continued for a period of 30 days or (b) in case default shall be made in the
payment of all or any part of the principal of any of the Securities of any
series when the same shall have become due and payable, whether upon maturity of
the Securities of such series or upon any redemption or by declaration or
otherwise, then upon demand of the Trustee, the Issuer will pay to the Trustee
for the benefit of the Holders of the Securities of such series the whole amount
that then shall have become due and payable on all Securities of such series,
and such Coupons, for principal or interest, as the case may be (with interest
to the date of such payment upon the overdue principal and, to the extent that
payment of such interest is enforceable under applicable law, on overdue
installments of interest at the same rate as the rate of interest or Yield to
Maturity (in the case of Original Issue Discount Securities) specified in the
Securities of such series); and in addition thereto, such further amount as
shall be sufficient to cover the costs and expenses of collection, including
reasonable compensation to the Trustee and each predecessor Trustee, their
respective agents, attorneys and counsel, and any reasonable expenses and
liabilities incurred, and all advances made, by the Trustee and each predecessor
Trustee.

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

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

other obligor upon the Securities under Title 11 of the United States Code or
any other applicable Federal or state bankruptcy, insolvency or other similar
law, or in case a receiver, assignee or trustee in bankruptcy or reorganization,
liquidator, sequestrator or similar official shall have been appointed for or

Securities, such portion of the principal amount as may be specified in the

advisable in order to have the claims of the Trustee (including any claim for
reasonable compensation to the Trustee and each predecessor Trustee, and their

and any trustee, receiver, or liquidator, custodian or other similar official is
hereby authorized by each of the Securityholders to make payments to the
Trustee, and, in the event that the Trustee shall consent to the making of
payments directly to the Securityholders, to pay to the Trustee such amounts as
shall be sufficient to cover reasonable compensation to the Trustee, each
predecessor Trustee and their respective agents, attorneys and counsel, and all
other expenses and liabilities incurred, and all advances made, by the Trustee
and each predecessor Trustee and any other amounts due the Trustee under Section
6.06.

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

      All rights of action and of asserting claims under this Indenture, or
under any of the Securities of any series or Coupons appertaining to such
Securities, may be enforced by the Trustee without the possession of any of the
Securities of such series or Coupons appertaining to such Securities or the
production thereof on any trial or other proceedings relative thereto, and any
such action or

proceedings instituted by the Trustee shall be brought in its own name as
trustee of an express trust, and any recovery of judgment, subject to the
payment of the expenses, disbursements and compensation of the Trustee, each
predecessor Trustee and their respective agents and attorneys, shall be for the
ratable benefit of the Holders of the Securities or Coupons appertaining to such
Securities in respect of which such action was taken.

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

      SECTION 5.03. Application of Proceeds. Any moneys collected by the Trustee
pursuant to this Article in respect of any series shall, subject to the
subordination provisions hereof, be applied in the following order at the date
or dates fixed by the Trustee and, in case of the distribution of such moneys on
account of principal or interest, upon presentation of the several Securities
and Coupons appertaining to such Securities in respect of which monies have been
collected and stamping (or otherwise noting) thereon the payment, or issuing
Securities of such series in reduced principal amounts in exchange for the
presented Securities of like series if only partially paid, or upon surrender
thereof if fully paid:

            FIRST: To the payment of costs and expenses applicable to such
      series in respect of which monies have been collected, including
      reasonable compensation to the Trustee and each predecessor Trustee and
      their respective agents and attorneys and of all reasonable expenses and
      liabilities incurred, and all advances made, by the Trustee and each
      predecessor Trustee and any other amounts due the Trustee under Section
      6.06, except as a result of negligence or willful misconduct;

            SECOND: In case the principal of the Securities of such series in
      respect of which moneys have been collected shall not have become and be
      then due and payable, to the payment of interest on the Securities of such
      series in default in the order of the maturity of the installments of such
      interest, with interest (to the extent that such interest has been
      collected by the Trustee) upon the overdue installments of interest at the
      same rate as the rate of interest or Yield to Maturity (in the case of
      Original Issue Discount Securities) specified in such Securities, such

      payments to be made ratably to the Persons entitled thereto, without
      discrimination or preference;

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

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

      SECTION 5.04. Suits for Enforcement. In case an Event of Default has
occurred, has not been waived and is continuing, the Trustee may in its
discretion proceed to protect and enforce the rights vested in it by this
Indenture by such appropriate judicial proceedings as the Trustee shall deem
most effectual to protect and enforce any of such rights, either at law or in
equity or in bankruptcy or otherwise, whether for the specific enforcement of
any covenant or agreement contained in this Indenture or in aid of the exercise
of any power granted in this Indenture or to enforce any other legal or
equitable right vested in the Trustee by this Indenture or by law.

      SECTION 5.05. Restoration of Rights on Abandonment of Proceedings. In case
the Trustee shall have proceeded to enforce any right under this Indenture and
such proceedings shall have been discontinued or abandoned for any reason, or
shall have been determined adversely to the Trustee, then and in every such case
the Issuer and the Trustee shall be restored respectively to their former
positions and rights hereunder, and all rights, remedies and powers of the
Issuer, the Trustee and the Securityholders shall continue as though no such
proceedings had been taken.

      SECTION 5.06. Limitations on Suits by Securityholders. No Holder of any
Security of any series or of any Coupon appertaining thereto shall have any
right by virtue or by availing of any provision of this Indenture to institute
any action or proceeding at law or in equity or in bankruptcy or otherwise upon
or under or with respect to this Indenture, or for the appointment of a trustee,
receiver, liquidator, custodian or other similar official or for any other
remedy hereunder, unless such Holder previously shall have given to the Trustee
written notice of default and of the continuance thereof, as hereinbefore
provided, and unless also the Holders of not less than 25% in aggregate
principal amount of the Securities of each affected series then Outstanding
(treated as a single class) shall have made written request upon the Trustee to
institute such action or proceedings in its own name as trustee hereunder and
shall have offered to the Trustee such reasonable indemnity as it may require
against the costs, expenses and liabilities to be incurred therein or thereby
and the Trustee for 60 days after its receipt of such notice, request and offer
of indemnity shall have failed to institute any such action or proceeding and no
direction inconsistent with such written request shall have been given to the
Trustee pursuant to Section 5.09; 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 any other such
Holder of 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, each and every
Securityholder and the Trustee shall be entitled to such relief as can be given
either at law or in equity.

      SECTION 5.07. Unconditional Right of Securityholders to Institute Certain
Suits. Notwithstanding any other provision in this Indenture and any provision
of any Security, the right of any Holder of any Security 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 Coupon, or to institute
suit for the enforcement of any such payment on or after such respective dates,
shall not be impaired or affected without the consent of such Holder.

      SECTION 5.08. Powers and Remedies Cumulative; Delay or Omission Not Waiver
of Default. Except as provided in Section 5.06, no right or remedy herein
conferred upon or reserved to the Trustee or to the Holders of Securities or
Coupons is intended to be exclusive of any other right or remedy, and every
right
<PAGE>

                                                                            PAGE

and remedy shall, to the extent permitted by law, be cumulative and in addition
to every other right and remedy given hereunder or now or hereafter existing at
law or in equity or otherwise. The assertion or employment of any right or
remedy hereunder, or otherwise, shall not prevent the concurrent assertion or
employment of any other appropriate right or remedy.

      No delay or omission of the Trustee or of any Holder of Securities or
Coupons to exercise any right or power accruing upon any Event of Default
occurring and continuing as aforesaid shall impair any such right or power or
shall be construed to be a waiver of any such Event of Default or an
acquiescence therein; and, subject to Section 5.06, every power and remedy given
by this Indenture or by law to the Trustee or to the Holders of Securities or
Coupons may be exercised from time to time, and as often as shall be deemed
expedient, by the Trustee or by the Holders of Securities or Coupons.

      SECTION 5.09. Control by Holders of Securities. The Holders of a majority
in aggregate principal amount of the Securities of each series affected (with
all such series voting as a single class) at the time Outstanding shall have the
right to direct the time, method, and place of conducting any proceeding for any
remedy available to the Trustee, or exercising any trust or power conferred on
the Trustee with respect to the Securities of such series by this Indenture;
provided that such direction shall not be otherwise than in accordance with law
and the provisions of this Indenture and provided further that (subject to the
provisions of Section 6.01) the Trustee shall have the right to decline to
follow any such direction if the Trustee, being advised by nationally recognized
counsel in writing or by an opinion of counsel, shall reasonably determine that
the action or proceeding so directed may not lawfully be taken or if the Trustee
in good faith by its board of directors, the executive committee, or a trust
committee of directors or Responsible Officers of the Trustee shall determine
that the action or proceedings so directed would involve the Trustee in personal
liability or if the Trustee in good faith shall so determine that the actions or
forebearances specified in or pursuant to such direction would be unduly
prejudicial to the interests of Holders of the Securities of all series so
affected not joining in the giving of said direction, it being understood that
(subject to Section 6.01) the Trustee shall have no duty to ascertain whether or
not such actions or forebearances are unduly prejudicial to such Holders.

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

      SECTION 5.10. Waiver of Past Defaults. Prior to the acceleration of the
maturity of any Securities as provided in Section 5.01, the Holders of a
majority in
<PAGE>

                                                                            PAGE

aggregate principal amount of the Securities of all series at the time
Outstanding with respect to which an Event of Default shall have occurred and be
continuing (voting as a single class) may on behalf of the Holders of all such
Securities waive any past default or Event of Default described in Section 5.01
and its consequences, except a default in respect of a covenant or provision
hereof which cannot be modified or amended without the consent of the Holder of
each Security affected. In the case of any such waiver, the Issuer, the Trustee
and the Holders of all such Securities shall be restored to their former
positions and rights hereunder, respectively; but no such waiver shall extend to
any subsequent or other default or impair any right consequent thereon.

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

      SECTION 5.11. Trustee to Give Notice of Default, But May Withhold in
Certain Circumstances. The Trustee shall, within ninety (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 actually known to the Trustee
(i) if any Unregistered Securities of a series affected are then Outstanding, to
the Holders thereof, by mail to such Holders who have filed their names and
addresses with the Trustee within the two years preceding the notice at such
addresses as were so furnished to the Trustee and (ii) if any Registered
Securities of a series affected are then Outstanding, by mailing notice to the
Holders of then Outstanding Registered Securities of each series affected at
their addresses as they shall appear on the registry books, unless in each case
such defaults shall have been cured before the mailing or publication of such
notice (the term "defaults" for the purpose of this Section being hereby defined
to mean any event or condition which is, or with notice or lapse of time or both
would become, an Event of Default); provided that, except in the case of default
in the payment of the principal of or interest on any of the Securities of such
series, or in the payment of any sinking fund installment on such series, the
Trustee shall be protected in withholding such notice if and so long as the
board of directors, the executive committee, or a trust committee of directors
or trustees and/or Responsible Officers of the Trustee in good faith determines
that the withholding of such notice is in the interests of the Securityholders
of such series.

      SECTION 5.12. Right of Court to Require Filing of Undertaking to Pay
Costs. All parties to this Indenture agree, and each Holder of any Security or
Coupon by his 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
<PAGE>

                                                                            PAGE

remedy under this Indenture or in any suit against the Trustee for any action
taken, suffered or omitted by it as Trustee, the filing by any party litigant in
such suit of an undertaking to pay the costs of such suit, and that such court
may in its discretion assess reasonable costs, including reasonable attorneys'
fees, against any party litigant in such suit, having due regard to the merits
and good faith of the claims or defenses made by such party litigant; but the
provisions of this Section shall not apply to any suit instituted by the
Trustee, to any suit instituted by any Securityholder or group of
Securityholders of any series holding in the aggregate more than 10% in
aggregate principal amount of the Securities of such series, or, in the case of
any suit relating to or arising under clause (c) or (f) of Section 5.01 (if the
suit relates to Securities of more than one but less than all series), 10% in
aggregate principal amount of Securities then Outstanding and affected thereby,
or in the case of any suit relating to or arising under clause (c) or (f) (if
the suit under clause (c) or (f) relates to all the Securities then
Outstanding), (d) or (e) of Section 5.01, 10% in aggregate principal amount of
all Securities then Outstanding, or to any suit instituted by any Securityholder
for the enforcement of the payment of the principal of or interest on any
Security on or after the due date expressed in such Security or any date fixed
for redemption.

                             CONCERNING THE TRUSTEE

      SECTION 6.01. Duties and Responsibilities of the Trustee; During Default;
Prior to Default. With respect to the Holders of any series of Securities issued
hereunder, the Trustee, prior to the occurrence of an Event of Default with
respect to the Securities of a particular series and after the curing or waiving
of all Events of Default which may have occurred with respect to such series,
undertakes to perform such duties and only such duties as are specifically set
forth in this Indenture. In case an Event of Default with respect to the
Securities of a series has occurred (which has not been cured or waived) the
Trustee shall exercise with respect to such series of Securities such of the
rights and powers vested in it by this Indenture, 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 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 wilful misconduct, except that

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

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

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

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

      (c) the Trustee shall not be liable with respect to any action taken or
omitted to be taken by it in good faith in accordance with the direction of the
Holders pursuant to Section 5.09 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 or in the exercise of any of
its rights or powers.

      The provisions of this Section 6.01 are in furtherance of and subject to
Section 315 of the Trust Indenture Act of 1939.

      SECTION 6.02. Certain Rights of the Trustee. In furtherance of and subject
to the Trust Indenture Act of 1939, and subject to Section 6.01:

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

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

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

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

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

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

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

Indenture shall not be construed as a duty unless so specified

herein; the Trustee shall not be liable in connection with the performance of
its duties hereunder, except for its own negligence or willful misconduct;

      (i) whenever in the administration of the trusts imposed upon it by this
Indenture the Trustee shall deem it necessary or desirable that a matter be
proved or established prior to taking or suffering any action hereunder, such
matter may be deemed to be conclusively proved and established by an Officer's
Certificate, and such Officer's Certificate shall be full warrant to the Trustee
for any action taken or suffered in good faith under the provisions of the
Indenture in reliance upon such Officer's Certificate, but in its discretion the
Trustee may, in lieu thereof, accept other evidence of such matter or may
request such additional evidence as it may deem reasonable;

      (j) whether or not therein expressly so provided, every provision of this
Indenture or other documents relating to the issuance of Securities, relating to
the conduct or affecting the liability of or affording protection to the
Trustee, shall be subject to the provisions of this Article;

      (k) the Trustee shall not be deemed to have notice or actual knowledge of
any Event of Default (other than an Event of Default described in Section
5.01(a) or (b)) unless and until it shall have actual knowledge thereof, or a
Responsible Officer shall have received written notice thereof at its principal
corporate trust office, including where required from Holders of not less than
25% in aggregate principal amount of the Securities of each affected series then
outstanding (treated as a single class). Except as otherwise expressly provided
herein, the Trustee shall not be bound to ascertain or inquire as to the
performance or observance of any of the terms, conditions, covenants or
agreements herein or of any of the documents executed in connection with the
Securities, or as to the existence of a default hereunder.

      SECTION 6.03. Trustee Not Responsible for Recitals, Disposition of
Securities or Application of Proceeds Thereof. The recitals contained herein and
in the Securities, except the Trustee's certificates of authentication, shall be
taken as the statements of the Issuer, and the Trustee assumes no responsibility
for the correctness of the same. The Trustee makes no representation as to the
validity or sufficiency of this Indenture or of the Securities or Coupons. The
Trustee shall not be accountable for the use or application by the Issuer of any
of the Securities or of the proceeds thereof.

      SECTION 6.04. Trustee and Agents May Hold Securities or Coupons;
Collections, etc. The Trustee or any agent of the Issuer or 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 the Trustee or such
agent and may otherwise deal with the Issuer and receive, collect, hold and
retain collections from the Issuer with the same rights it would have if it were
not the Trustee or such agent.

      SECTION 6.05. Moneys Held by Trustee. Subject to the provisions of Section
10.04 hereof, all moneys received by the Trustee shall, until used or applied as
herein provided, be held in trust for the purposes for which they were received,
but need not be segregated from other funds except to the extent required by
mandatory provisions of law. Neither the Trustee nor any agent of the Issuer or
the Trustee shall be under any liability for interest on any moneys received by
it hereunder.

      SECTION 6.06. Compensation and Indemnification of Trustee and Its Prior
Claim. The Issuer covenants and agrees to pay to the Trustee from time to time,
and the Trustee shall be entitled to, reasonable compensation (which shall not
be limited by any provision of law in regard to the compensation of a trustee of
an express trust) and the Issuer covenants and agrees to pay or reimburse the
Trustee and each predecessor Trustee upon its request for all reasonable
expenses, disbursements and advances incurred or made by or on behalf of it in
accordance with any of the provisions of this Indenture (including the
reasonable compensation and the expenses and disbursements of its counsel and of
all agents and other Persons not regularly in its employ) except any such
expense, disbursement or advance as may be reasonably determined to arise from
its negligence or willful misconduct. The Issuer also covenants to indemnify the
Trustee and each predecessor Trustee for, and to hold it harmless against, any
loss, liability or expense incurred without negligence or willful misconduct on
its part, arising out of or in connection with the acceptance or administration
of this Indenture or the trusts hereunder and its duties hereunder, reasonable
costs and expenses of defending itself against or investigating any claim of
liability in the premises. The obligations of the Issuer under this Section to
compensate and indemnify the Trustee and each predecessor Trustee and to pay or
reimburse the Trustee and each predecessor Trustee for reasonable expenses,
disbursements and advances shall constitute additional indebtedness hereunder
and shall survive the satisfaction and discharge of this Indenture. Such
additional indebtedness shall be a senior claim to that of the Securities upon
all property and funds held or collected by the Trustee as such, except funds
held in trust for the benefit of the Holders of particular Securities or
Coupons, and the Securities are hereby subordinated to such senior claim.

      SECTION 6.07. Right of Trustee to Rely on Officer's Certificate, etc .
Subject to Sections 6.01 and 6.02, whenever in the administration of the trusts
of this Indenture the Trustee shall deem it necessary or desirable that a matter
be proved or established prior to taking or suffering or omitting any action
hereunder, such matter (unless other evidence in respect thereof be herein
specifically prescribed) may, be deemed to be conclusively proved and
established by an Officer's Certificate delivered to the Trustee unless there
was negligence or willful misconduct on the part of the Trustee in relying on
such certificate, and such

                                                                            ----

certificate, shall be full warrant to the Trustee for any action taken, suffered
or omitted by it under the provisions of this Indenture upon the good faith
thereof unless there was negligence or willful misconduct on the part of the
Trustee in relying on such certificate.

      SECTION 6.08. Conflicting Interests of Trustee. If the Trustee has or
shall acquire a conflicting interest within the meaning of the Trust Indenture
Act, the Trustee shall either eliminate such interest or resign, to the extent
and in the manner provided by, and subject to the provisions of, the Trust
Indenture Act and this Indenture. Notwithstanding anything in this Indenture to
the contrary, the Issuer and the Trustee acknowledge that the Trustee is acting
as trustee both under this Indenture and under an indenture dated the date
hereof in connection with certain of the Company's senior debt securities and
upon a default or an Event of Default under either or both indentures, a
conflict of interest may arise which would require the Trustee to resign as
Trustee from either or both indentures.

      SECTION 6.09. Persons Eligible for Appointment as Trustee. The Trustee for
each series of Securities hereunder shall at all times be a corporation
organized and doing business under the laws of the United States of America or
of any State or the District of Columbia having (or in the case of a corporation
included in a bank holding company system, the related bank holding company
shall have) a combined capital and surplus of at least $50,000,000, and which is
authorized under such laws to exercise corporate trust powers and is subject to
supervision or examination by Federal, State or District of Columbia authority.
Such corporation shall have an established place of business or agency in the
Borough of Manhattan, The City of New York if there be such a corporation in
such location willing to act upon reasonable and customary terms and conditions.
If such corporation publishes reports of condition at least annually, pursuant
to law or to the requirements of the aforesaid supervising or examining
authority, then for the purposes of this Section, the combined capital and
surplus of such corporation shall be deemed to be its combined capital and
surplus as set forth in its most recent report of condition so published. In
case at any time the Trustee shall cease to be eligible in accordance with the
provisions of this Section, the Trustee shall resign immediately in the manner
and with the effect specified in Section 6.10.

      The provisions of this Section 6.09 are in furtherance of and subject to
Section 310(a) of the Trust Indenture Act of 1939.

      SECTION 6.10. Resignation and Removal; Appointment of Successor Trustee.
(a) The Trustee, or any trustee or trustees hereafter appointed, may at any time
resign with respect to one or more or all series of Securities by giving written
notice of resignation to the Issuer and by mailing notice of such resignation to
the
<PAGE>

                                                                            PAGE
                                                                            ----

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

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

      (i) the Trustee shall fail to comply with the provisions of Section 310(b)
of the Trust Indenture Act of 1939 with respect to any series of Securities
after written request therefor by the Issuer or by any Securityholder who has
been a bona fide Holder of a Security or Securities of such series for at least
six months; or

      (ii) the Trustee shall cease to be eligible in accordance with the
provisions of Section 6.09 and Section 310(a) of the Trust Indenture Act of 1939
and shall fail to resign after written request therefor by the Issuer or by any
Securityholder; or

      (iii) the Trustee shall become incapable of acting with respect to any
series of Securities, or shall be adjudged a bankrupt or insolvent, or a
receiver or liquidator of the Trustee or of its property shall be appointed, or
any public officer shall take charge or control of the Trustee or of its
property or affairs for the purpose of rehabilitation, conservation or
liquidation; then, in any such case, the Issuer may remove the Trustee with
respect to the applicable series of Securities and appoint a successor trustee
for such series by written instrument, in duplicate, executed by order of the
Board of Directors of the Issuer, one copy of which instrument shall be
delivered to the Trustee so removed and one copy to the successor trustee, or,
subject to the provisions of Section 315(e) of the Trust Indenture Act of 1939,
any Securityholder who has been a bona fide Holder of a Security or Securities
of such series for at least six months may on behalf of himself and all others
similarly situated, petition any court of competent jurisdiction for the removal
of the Trustee and the appointment of a successor trustee with respect to such
series. Such court may thereupon, after such notice, if any, as it may deem
proper and prescribe, remove the Trustee and appoint a successor trustee.

     (c) The Holders of a majority in aggregate principal amount of the
Securities of each series at the time outstanding may at any time remove the
Trustee with respect to Securities of such series and appoint a successor
trustee with respect to the Securities of such series by delivering to the
Trustee so removed, to the successor trustee so appointed and to the Issuer the
evidence provided for in Section 7.01 of the action in that regard taken by the
Securityholders.

     (d) Any resignation or removal of the Trustee with respect to any series
and any appointment of a successor trustee with respect to such series pursuant
to any of the provisions of this Section 6.10 shall become effective upon
acceptance of appointment by the successor trustee as provided in Section 6.11.

      SECTION 6.11. Acceptance of Appointment by Successor Trustee. Any
successor trustee appointed as provided in Section 6.10 shall execute and
deliver to the Issuer and to its predecessor trustee an instrument accepting
such appointment hereunder, and thereupon the resignation or removal of the
predecessor trustee with respect to all or any applicable series shall become
effective and such successor trustee, without any further act, deed or
conveyance, shall become vested with all rights, powers, duties and obligations
with respect to such series of its predecessor hereunder, with like effect as if
originally named as trustee for such series hereunder; but, nevertheless, on the
written request of the Issuer or of the successor trustee, upon payment of its
charges then unpaid, the trustee ceasing to act shall, subject to Section 10.04,
pay over to the successor trustee all moneys at the time held by it hereunder
and shall execute and deliver an instrument transferring to such successor
trustee all such rights, powers, duties and obligations. Upon reasonable request
of any such successor trustee, the Issuer shall execute any and all reasonable
instruments in writing for more fully and certainly vesting in and confirming to
such successor trustee all such rights and powers. Any trustee ceasing to act
shall, nevertheless, retain a prior claim upon all property or funds held or
collected by such trustee to secure any amounts then due it pursuant to the
provisions of Section 6.06.

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

                                                                            PAGE
                                                                            ----

      No successor trustee with respect to any series of Securities shall accept
appointment as provided in this Section 6.11 unless at the time of such
acceptance such successor trustee shall be qualified under Section 310(b) of the
Trust Indenture Act of 1939 and eligible under the provisions of Section 6.09.

      Upon acceptance of appointment by any successor trustee as provided in
this Section 6.11, the successor trustee shall give notice thereof (i) if any
Unregistered Securities of a series affected are then Outstanding, to the
Holders thereof, by mail to such Holders who have filed their names and
addresses with the Trustee within the two years preceding the notice at such
addresses as were so furnished to the Trustee and (ii) if any Registered
Securities of a series affected are then Outstanding, by mailing notice to the
Holders of then Outstanding Registered Securities of each series affected at
their addresses as they shall appear on the registry books. If the acceptance of
appointment is substantially contemporaneous with the resignation, then the
notice called for by the preceding sentence may be combined with the notice
called for by Section 6.10.

      SECTION 6.12. Merger, Conversion, Consolidation or Succession to Business
of Trustee. Any corporation into which the Trustee may be merged or converted or
with which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any
corporation succeeding by sale or otherwise to all or substantially all of the
corporate trust business of the Trustee, shall be the successor of the Trustee
hereunder, provided that such corporation shall be qualified under Section
310(b) of the Trust Indenture Act of 1939 and eligible under the provisions of
Section 6.09, 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 of any series shall have
been authenticated but not delivered, any such successor to the Trustee may
adopt the certificate of authentication of any predecessor Trustee and deliver
such Securities so authenticated; and, in case at that time any of the
Securities of any series shall not have been authenticated, any successor to the
Trustee may authenticate such Securities either in the name of any predecessor
hereunder or in the name of the successor Trustee; and in all such cases such
certificate shall have the full force which it is anywhere in the Securities of
such series or in this Indenture provided that the certificate of the Trustee
shall have; provided, that the right to adopt the certificate of authentication
of any predecessor Trustee or to authenticate Securities of any series in the
name of any predecessor Trustee shall apply only to its successor or successors
by merger, conversion or consolidation.

      SECTION 6.13. Preferential Collection of Claims. If and when the Trustee
shall be or become a creditor of the Issuer (or any other obligor upon the
Securities of any series), the Trustee shall be subject to the provisions of the
Trust Indenture Act regarding the collection of the claims against the Issuer
(or any such other obligor).

      SECTION 6.14. 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 Issuer an authenticating agent (the
"Authenticating Agent") which shall be authorized to act on behalf of the
Trustee to authenticate Securities, including Securities issued upon exchange,
registration of transfer, partial redemption or pursuant to Section 2.09.
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 $5,000,000 (determined as provided in Section
6.09 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 by sale or otherwise to the
corporate agency business of any Authenticating Agent, shall continue to be the
Authenticating Agent with respect to all series of Securities for which it
served as Authenticating Agent without the execution or filing of any paper or
any further act on the part of the Trustee or such Authenticating Agent. Any
Authenticating Agent may at any time, and if it shall cease to be eligible
shall, resign by giving written notice of resignation to the Trustee and to the
Issuer.

      Upon receiving such a notice of resignation or upon such a termination, or
in case at any time any Authenticating Agent shall cease to be eligible in
accordance with the provisions of this Section 6.14 with respect to one or more
series of Securities, the Trustee shall upon receipt of an Issuer Order appoint
a successor Authenticating Agent and the Issuer shall provide notice of such
appointment to all Holders of Securities of such series in the manner and to the
extent provided in
<PAGE>

                                                                            PAGE

Section 11.04. Any successor Authenticating Agent upon acceptance of its
appointment hereunder shall become vested with all rights, powers, duties and
responsibilities of its predecessor hereunder, with like effect as if originally
named as Authenticating Agent. The Issuer agrees to pay to the Authenticating
Agent for such series from time to time reasonable compensation. The
Authenticating Agent for the Securities of any series shall have no
responsibility or liability for any action taken by it as such at the direction
of the Trustee.

      The rights and protections from liability provided in this Article shall
be applicable to any Authenticating Agent.

                                    ARTICLE 7
                         CONCERNING THE SECURITYHOLDERS

      SECTION 7.01. Evidence of Action Taken by Securityholders. Any request,
demand, authorization, direction, notice, consent, waiver or other action
provided by this Indenture to be given or taken by a specified percentage in
principal amount of the Securityholders of any or all series may be embodied in
and evidenced by one or more instruments of substantially similar tenor signed
by such specified percentage of Securityholders in person or by agent duly
appointed in writing; and, except as herein otherwise expressly provided, such
action shall become effective when such instrument or instruments are delivered
to the Trustee. Proof of execution of any instrument or of a writing appointing
any such agent shall be sufficient for any purpose of this Indenture and
(subject to Sections 6.01 and 6.02) conclusive in favor of the Trustee and the
Issuer, if made in the manner provided in this Article.

      SECTION 7.02. Proof of Execution of Instruments and of Holding of
Securities. Subject to Sections 6.01 and 6.02, the execution of any instrument
by a Securityholder or his agent or proxy may be proved in the following manner:

     (a) The fact and date of the execution by any Holder of any instrument may
be proved by the certificate of any notary public or other officer of any
jurisdiction authorized to take acknowledgments of deeds or administer oaths
that the person executing such instruments acknowledged to him the execution
thereof, or by an affidavit of a witness to such execution sworn to before any
such notary or other such officer. Where such execution is by or on behalf of
any legal entity other than an individual, such certificate or affidavit shall
also constitute sufficient proof of the authority of the person executing the
same. The fact of the holding by any Holder of an Unregistered Security of any
<PAGE>

                                                                            PAGE
                                                                            ----

series, and the identifying number of such Security and the date of his holding
the same, may be proved by the production of such Security or by a certificate
executed by any trust company, bank, banker or recognized securities dealer
wherever situated satisfactory to the Trustee, if such certificate shall be
deemed by the Trustee to be satisfactory. Each such certificate shall be dated
and shall state that on the date thereof a Security of such series bearing a
specified identifying number was deposited with or exhibited to such trust
company, bank, banker or recognized securities dealer by the Person named in
such certificate. Any such certificate may be issued in respect of one or more
Unregistered Securities of one or more series specified therein. The holding by
the Person named in any such certificate of any Unregistered Securities of any
series specified therein shall be presumed to continue for a period of one year
from the date of such certificate unless at the time of any determination of
such holding (i) another certificate bearing a later date issued in respect of
the same Securities shall be produced, or (ii) the Security of such series
specified in such certificate shall be produced by some other Person, or (iii)
the Security of such series specified in such certificate shall have ceased to
be Outstanding. Subject to Sections 6.01 and 6.02, the fact and date of the
execution of any such instrument and the amount and numbers of Securities of any
series held by the Person so executing such instrument and the amount and
numbers of any Security or Securities for such series may also be proven in
accordance with such reasonable rules and regulations as may be prescribed by
the Trustee for such series or in any other manner which the Trustee for such
series may deem sufficient.

      (b) In the case of Registered Securities, the ownership of such Securities
shall be proved by the Security register or by a certificate of the Security
registrar.

      The Issuer may set a record date for purposes of determining the identity
of Holders of Registered Securities of any series entitled to vote or consent to
any action referred to in Section 7.01, which record date may be set at any time
or from time to time by notice to the Trustee, for any date or dates (in the
case of any adjournment or reconsideration) not more than 60 days nor less than
five days prior to the proposed date of such vote or consent, and thereafter,
notwithstanding any other provisions hereof, with respect to Registered
Securities of any series, only Holders of Registered Securities of such series
of record on such record date shall be entitled to so vote or give such consent
or revoke such vote or consent.

      SECTION 7.03. Holders to Be Treated as Owners. The Issuer, the Trustee and
any agent of the Issuer or the Trustee may deem and treat the Person in whose
name any Security shall be registered upon the Security register for such series
as the absolute owner of such Security (whether or not such Security shall be
overdue and notwithstanding any notation of ownership or other writing thereon)
for the purpose of receiving payment of or on account of the principal of and,
subject to the provisions of this Indenture, interest on such Security and for
all
<PAGE>

                                                                            PAGE
                                                                            ----

other purposes; and neither the Issuer nor the Trustee nor any agent of the
Issuer or the Trustee shall be affected by any notice to the contrary. The
Issuer, the Trustee and any agent of the Issuer 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 Issuer,
the Trustee, nor any agent of the Issuer 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.

      SECTION 7.04. Securities Owned by Issuer Deemed Not Outstanding. In
determining whether the Holders of the requisite aggregate principal amount of
Outstanding Securities of any or all series have concurred in any direction,
consent or waiver under this Indenture, Securities which are owned by the Issuer
or any other obligor on the Securities with respect to which such determination
is being made or by any Person directly or indirectly controlling or controlled
by or under direct or indirect common control with the Issuer or any other
obligor on the Securities with respect to which such determination is being made
shall be disregarded and deemed not to be Outstanding for the purpose of any
such determination, except that for the purpose of determining whether the
Trustee shall be protected in relying on any such direction, consent or waiver
only Securities which the Trustee knows are so owned shall be so disregarded.
Securities so owned which have been pledged in good faith may be regarded as
Outstanding if the pledgee establishes to the satisfaction of the Trustee the
pledgee's right so to act with respect to such Securities and that the pledgee
is not the Issuer or any other obligor upon the Securities or any Person
directly or indirectly controlling or controlled by or under direct or indirect
common control with the Issuer or any other obligor on the Securities. In case
of a dispute as to such right, the advice of nationally recognized counsel shall
be full protection in respect of any decision made by the Trustee in accordance
with such advice. Upon request of the Trustee, the Issuer shall furnish to the
Trustee promptly an Officer's Certificate listing and identifying all
Securities, if any, known by the Issuer to be owned or held by or for the
account of any of the above-described Persons; and, subject to Sections 6.01 and
6.02, the Trustee shall be entitled to accept such Officer's Certificate as
conclusive evidence of the facts therein set forth and of the fact that all
Securities not listed therein are Outstanding for the purpose of any such
determination.

      SECTION 7.05. Right of Revocation of Action Taken. At any time prior to
(but not after) the evidencing to the Trustee, as provided in Section 7.01, of
the taking
<PAGE>

                                                                            PAGE

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

      SECTION 8.01. Supplemental Indentures Without Consent of Securityholders.
The Issuer, when authorized by a resolution of its Board of Directors (which
resolution may provide general terms or parameters for such action and may
provide that the specific terms of such action may be determined in accordance
with or pursuant to an Issuer Order), and the Trustee may from time to time and
at any time enter into an indenture or indentures supplemental hereto for one or
more of the following purposes:

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

      (b) to evidence the succession of another corporation to the Issuer, or
successive successions, and the assumption by the successor corporation of the
covenants, agreements and obligations of the Issuer pursuant to Article 9;

      (c) to add to the covenants of the Issuer such further covenants,
restrictions, conditions or provisions as the Issuer and the Trustee shall
consider to be for the protection of the Holders of Securities or Coupons, and
to make the occurrence, or the occurrence and continuance, of a default in any

covenant, restriction, condition or provision such supplemental indenture may
provide for a particular period of grace after default (which period may be
shorter or longer than that allowed in the case of other defaults) or may
provide for an immediate enforcement upon such an Event of Default or may limit
the remedies available to the Trustee upon such an Event of Default or may limit
the right of the Holders of a majority in aggregate principal amount of the
Securities of such series to waive such an Event of Default;

      (d) to cure any ambiguity or to correct or supplement any provision
contained herein or in any supplemental indenture which may be defective or
inconsistent with any other provision contained herein or in any supplemental
indenture, or to make any other provisions as the Issuer may deem necessary or
desirable, provided that no such action shall materially adversely affect the
interests of the Holders of the Securities or Coupons;

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

      (f) to provide for the issuance under this Indenture of Securities of a
series in coupon form (including Securities registrable as to principal only)
and to provide for exchangeability of such Securities with the Securities issued
hereunder in fully registered form and to make all appropriate changes for such
purpose;

      (g) to modify, eliminate or add to the provisions of this Indenture to
such extent as shall be necessary to effect the qualifications of this Indenture
under the Trust Indenture Act, or under any similar federal statute hereafter
enacted; and

      (h) to evidence and provide for the acceptance of appointment hereunder by
a successor trustee with respect to the Securities of one or more series and to
add to or change any of the provisions of this Indenture as shall be necessary
to provide for or facilitate the administration of the trusts hereunder by more
than one trustee, pursuant to the requirements of Section 6.11.

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

      Any supplemental indenture authorized by the provisions of this Section
may be executed without the consent of the Holders of any of the Securities at
the time outstanding, notwithstanding any of the provisions of Section 8.02.

Outstanding of all series affected by such supplemental indenture (voting as one
class), the Issuer, when authorized by a resolution of its Board of Directors
(which resolution may provide general terms or parameters for such action and
may provide that the specific terms of such action may be determined in
accordance with or pursuant to an Issuer Order), and the Trustee may, from time
to time and at any time, enter into an indenture or indentures supplemental
hereto 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 of the Coupons appertaining to such
Securities; provided, that no such supplemental indenture shall (a)(i) extend
the final maturity of any Security, (ii) reduce the principal amount thereof,
(iii) reduce the rate or extend the time of payment of interest thereon, (iv)
reduce any amount payable on redemption thereof, (v) make the principal thereof
(including any amount in respect of original issue discount), or interest
thereon payable in any coin or currency other than that provided in the
Securities and Coupons or in accordance with the terms thereof, (vi) modify or
amend any provisions for converting any currency into any other currency as
provided in the Securities or Coupons or in accordance with the terms thereof,

Securities or Coupons for securities of the Issuer or of other entities or other
property (or the cash value thereof), including the determination of the amount
of securities or other property (or cash) into which the Securities shall be
converted or exchanged, other than as provided in the antidilution provisions or
other similar adjustment provisions of the Securities or Coupons or otherwise in
accordance with the terms thereof, (ix) alter the provisions of Section 11.11 or
11.12 or impair or affect the right of any Securityholder to institute suit for
the payment thereof or, if the Securities provide therefor, any right of
repayment at the option of the Securityholder, in each case without the consent
of the Holder of each Security so affected, or (b) reduce the aforesaid
percentage of Securities of any series, the consent of the Holders of which is
required for any such supplemental indenture, without the consent of the Holders
of each Security so affected.

      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 Issuer, accompanied by a copy of a resolution of
the Board of Directors (which resolution may provide general terms or parameters
for such action and may provide that the specific terms of such action may be
determined in accordance with or pursuant to an Issuer Order) certified by the
secretary or an assistant secretary of the Issuer authorizing the execution of
any such supplemental indenture, and upon the filing with the Trustee of
evidence of the consent of the Holders of the Securities as aforesaid and other
documents, if any, required by Section 7.01, the Trustee shall join with the
Issuer in the execution of such supplemental indenture unless such supplemental
indenture affects the Trustee's own rights, duties or immunities under this
Indenture or otherwise, in which case the Trustee may in its discretion, but
shall not be obligated to, enter into such supplemental indenture.

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

      Promptly after the execution by the Issuer and the Trustee of any
supplemental indenture pursuant to the provisions of this Section, the Trustee
shall give notice thereof (i) if any Unregistered Securities of a series
affected are then Outstanding, to the Holders thereof by mail to such Holders
who have filed their names and addresses with the Trustee within the two years
preceding the notice at such addresses as were so furnished to the Trustee and
(ii) if any Registered Securities of a series affected are then Outstanding, by
mailing notice thereof by first class mail to the Holders of then Outstanding
Registered Securities of each series affected at their addresses as they shall
appear on the registry books, and in each case such notice shall set forth in
general terms the substance of such supplemental indenture. Any failure of the
Issuer to give such notice, or any defect therein, shall not, however, in any
way impair or affect the validity of any such supplemental indenture.

      SECTION 8.03. Effect of Supplemental Indenture. Upon the execution of any
supplemental indenture pursuant to the provisions hereof, this Indenture shall
be and be deemed to be modified and amended in accordance therewith and the
respective rights, limitations of rights, obligations, duties and immunities
under this Indenture of the Trustee, the Issuer and the Holders of Securities of
each series affected thereby shall thereafter be determined, exercised and
enforced hereunder subject in all respects to such modifications and amendments,
and all the terms and conditions of any such supplemental indenture shall be and
be deemed to be part of the terms and conditions of this Indenture for any and
all purposes.

      SECTION 8.04. Documents to Be Given to Trustee. The Trustee shall be
entitled to receive (and subject to the provisions of Sections 6.01 and 6.02)
shall be fully protected in relying upon an Officer's Certificate and an Opinion
of Counsel as conclusive evidence that any supplemental indenture executed
pursuant to this Article 8 is permitted by and complies with the applicable
provisions of this Indenture.

      SECTION 8.05. Notation on Securities in Respect of Supplemental
Indentures. Securities of any series authenticated and delivered after the
execution of any supplemental indenture pursuant to the provisions of this
Article may bear a notation in form approved by the Trustee for such series as
to any matter provided for by such supplemental indenture or as to any action
taken by Securityholders. If the Issuer or the Trustee shall so determine, new
Securities of any series so modified as to conform, in the opinion of the
Trustee and the Board of Directors, to any modification of this Indenture
contained in any such supplemental indenture may be prepared by the Issuer,
authenticated by the Trustee and delivered in exchange for the Securities of
such series then Outstanding.

      SECTION 8.06. Subordination Unimpaired. This Indenture may not be amended
to alter the subordination of any of the Outstanding Securities without the
written consent of each holder of Senior Indebtedness then outstanding that
would be adversely affected thereby.

      SECTION 9.01. Issuer May Consolidate, Etc. on Certain Terms. Subject to
the provisions of Section 9.02, nothing contained in this Indenture or in any of
the Securities shall prevent any consolidation or merger of the Issuer with or
into any other Person or Persons (whether or not affiliated with the Issuer), or
successive consolidations or mergers in which the Issuer or its successor or
successors shall be a party or parties, or shall prevent any sale, conveyance or
lease (or successive sales, conveyances or leases) of all or substantially all
of the property of the Issuer, to any other Person (whether or not affiliated
with the Issuer), authorized to acquire and operate the same and that shall be
organized under the laws of the United States of America, any state thereof or
the District of Columbia; provided, however, that upon any such consolidation,
merger, sale, conveyance or lease, the due and punctual payment of the principal
of and premium, if any, and interest on all of the Securities, according to
their tenor and the due and punctual performance and observance of all of the
covenants and conditions of this Indenture to be performed by the Issuer, shall
be expressly assumed, by supplemental indenture satisfactory in form to the
Trustee, executed and delivered to the Trustee by the Person (if other than the
Issuer) formed by such consolidation, or into which the Issuer shall have been
merged, or by the Person that shall have acquired or leased such property, and
such supplemental indenture shall provide for conversion rights (if applicable).

      SECTION 9.02. Successor Corporation to be Substituted. In case of any such
consolidation, merger, sale, conveyance or lease and upon the assumption by the
successor Person, by supplemental indenture, executed and delivered to the
Trustee and satisfactory in form to the Trustee, of the due and punctual payment
of the principal of and premium, if any, and interest on all of the Securities
and the due and punctual performance of all of the covenants and conditions of
this Indenture to be performed by the Issuer, such successor Person shall
succeed to and be substituted for the Issuer, with the same effect as if it had
been named herein as the party of this first part. Such successor Person
thereupon may cause to be signed, and may issue either in its own name or in the
name of NVIDIA Corporation any or all of the Securities, issuable hereunder that
theretofore shall not have been signed by the Issuer and delivered to the
Trustee; and, upon the order of such successor Person instead of the Issuer and
subject to all the terms, conditions and limitations in this Indenture
prescribed, the Trustee shall authenticate and shall deliver, or cause to be
authenticated and delivered, any Securities that previously shall have been
signed and delivered by the officers of

successor Person thereafter shall cause to be signed and delivered to the
Trustee for that purpose. All the Securities so issued shall in all respects
have the same legal rank and benefit under this Indenture as the Securities
theretofore or thereafter issued in accordance with the terms of this Indenture
as though all of such Securities had been issued at the date of the execution
hereof. In the event of any such consolidation, merger, sale, conveyance or
lease, the Person named as the "Issuer" in the first paragraph of this Indenture
or any successor that shall thereafter have become such in the manner prescribed
in this Article 9 may be dissolved, wound up and liquidated at any time
thereafter and such Person shall be released from its liabilities as obligor and
maker of the Securities and from its obligations under this Indenture.

      In case of any such consolidation, merger, sale, conveyance or lease, such
changes in phraseology and form (but not in substance) may be made in the
Securities thereafter to be issued as may be appropriate.

cancellation shall have become due and payable, or are by their terms to become
due and payable within one year or are to be called for redemption within one
year under arrangements satisfactory to the Trustee for the giving of notice of

report, as to the sufficiency of the deposited amount, from an independent
certified accountant or other financial professional satisfactory to the

payable thereunder by the Issuer, then this Indenture shall cease to be of
further effect (except as to (i) remaining rights of registration of transfer,
substitution and exchange and conversion of Securities of such series and of

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 need not be
segregated from other funds except to the extent required by law.

two years after the date upon which such principal or interest shall have become
due and payable, shall, upon the written request of the Issuer and unless
otherwise required by mandatory provisions of applicable escheat or abandoned or
unclaimed property law, be repaid to the Issuer by the Trustee for such series
or such paying agent free from the trusts created by this Indenture, and the
Holder of the Securities of such series and of any Coupons appertaining thereto
shall, unless otherwise required by mandatory provisions of applicable escheat
or abandoned or unclaimed property laws, thereafter look only to the Issuer for
any payment which such Holder may be entitled to collect, and all liability of
the Trustee or any paying agent with respect to such moneys shall thereupon
cease; provided, however, that the Trustee or such paying agent, before being
required to make any such repayment with respect to moneys deposited with it for
any payment in respect of Registered Securities of any series, may at the
expense of the Issuer, mail by first-class mail to Holders of such Securities at
their addresses as they shall appear on the Security register, notice, that such
moneys remain and that, after a date specified therein, which shall not be less

thereof by mail or overnight delivery service) to each Holder entitled thereto,
at his last address as it appears in the Security register. In any case where
notice to such Holders is given by mail, neither the failure to mail such
notice, nor any defect in any notice so mailed, to any particular Holder shall
affect the sufficiency of such notice with respect to other Holders. Where this
Indenture provides for notice in any manner, such notice may be waived in
writing by the Person entitled to receive such notice, either before or after
the event, and such waiver shall be the equivalent of such notice. Waivers of
notice by Holders shall be filed with the Trustee, but such filing shall not be
a condition precedent to the validity of any action taken in reliance upon such
waiver.

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

      SECTION 11.05. Officer's Certificates and Opinions of Counsel; Statements
to Be Contained Therein. Upon any application or demand by the Issuer to the
Trustee to take any action under any of the provisions of this Indenture, the
Issuer shall furnish to the Trustee an Officer's Certificate stating that all
conditions precedent provided for in this Indenture relating to the proposed
action have been complied with and an Opinion of Counsel stating that in the
opinion of such counsel all such conditions precedent have been complied with,
except that in the case of any such application or demand as to which the
furnishing of such documents is specifically required by any provision of this
Indenture relating to

such particular application or demand, no additional certificate or opinion need
be furnished.

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

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

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

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

      SECTION 11.06. Payments Due on Saturdays, Sundays and Holidays. If the
date of maturity of interest on or principal of the Securities of any series or
any Coupons appertaining thereto or the date fixed for redemption or repayment
of any such Security or Coupon shall not be a Business Day, then payment of
interest or principal need not be made on such date, but may be made on the next
succeeding Business Day with the same force and effect as if made on the date of
maturity or the date fixed for redemption, and no interest shall accrue for the
period after such date.

      SECTION 11.07. Conflict of Any Provision of Indenture with Trust Indenture
Act of 1939. If and to the extent that any provision of this Indenture limits,
qualifies or conflicts with the duties imposed by, or with another provision (an
"incorporated provision") included in this Indenture by operation of, Sections
310 to 318, inclusive, of the Trust Indenture Act of 1939, such imposed duties
or incorporated provision shall control.

      SECTION 11.08. New York Law to Govern. This Indenture and each Security
and Coupon shall be deemed to be a contract under the laws of the State of New
York, and for all purposes shall be construed in accordance with the laws of
such State, except as may otherwise be required by mandatory provisions of law.

      SECTION 11.09. Counterparts. This Indenture may be executed in any number
of counterparts, each of which shall be an original; but such counterparts shall
together constitute but one and the same instrument.

      SECTION 11.10. Effect of Headings. The Article and Section headings herein
and the Table of Contents are for convenience only and shall not affect the
construction hereof.

      SECTION 11.11. Securities in a Foreign Currency. 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 Dollars, 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 Dollars that could be obtained for such
amount at the Market Exchange Rate. For purposes of this Section 11.11, Market
Exchange Rate shall mean the noon Dollar buying rate in New York City for cable
transfers of that currency published by the Federal Reserve Bank of New York. 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 as of the most recent available date, or
quotations from one or more major banks in The City of New York or in the
country of issue of the currency in question, or such other quotations 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.

      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 Issuer and all Holders.

      SECTION 11.12. Judgment Currency. The Issuer 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 a 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

                                   ARTICLE 12
                   REDEMPTION OF SECURITIES AND SINKING FUNDS

      SECTION 12.01. Applicability of Article. The provisions of this Article
shall be applicable to the Securities of any series which are redeemable before
their maturity or to any sinking fund for the retirement of Securities of a
series except as otherwise specified as contemplated by Section 2.03 for
Securities of such series.

      SECTION 12.02. 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 Issuer shall be given by mailing
notice of such redemption by first class mail, postage prepaid, or sent by
overnight delivery service or by telecopy (with written confirmation thereof by
mail or overnight delivery service), to such Holders of Securities of such
series at their last addresses as they shall appear upon the registry books at
least 30 days and not more than 60 days prior to the date fixed for redemption,
or within such other redemption notice period as has been designated for any
Securities of such series pursuant to Section 2.03 or 2.04 (the "Redemption
Notice Period"). 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 within two years preceding such notice of redemption, shall be
given by mailing notice of such redemption, by first class mail, postage
prepaid, or sent by overnight delivery service or by telecopy (with written
confirmation thereof by mail or overnight delivery service), at least 30 and not
more than 60 days prior to the date fixed for redemption or within any
applicable Redemption Notice Period to such Holders at such addresses as were so
furnished to the Trustee (and, in the case of any such notice given by the
Issuer, the Trustee shall make such information available to the Issuer for such
purpose). 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 any other 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 (or if not then ascertainable,
the
<PAGE>

                                                                            PAGE
                                                                            ----

manner of calculation thereof), 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 Issuer shall be given by the Issuer or, at the Issuer's request,
by the Trustee in the name and at the expense of the Issuer.

      On or before the redemption date specified in the notice of redemption
given as provided in this Section, the Issuer will deposit with the Trustee or
with one or more paying agents (or, if the Issuer is acting as its own paying
agent, set aside, segregate and hold in trust as provided in Section 3.04) an
amount of money or other property sufficient to redeem on the redemption date
all the Securities of such series so called for redemption at the appropriate
redemption price, together with accrued interest to the date fixed for
redemption. The Issuer will deliver to the Trustee at least 45 days prior to the
date fixed for redemption (or such shorter period of time as may be acceptable
to the Trustee) an Officer's Certificate stating the aggregate principal amount
of Securities to be redeemed. In case of a redemption at the election of the
Issuer prior to the expiration of any restriction on such redemption, the Issuer
shall deliver to the Trustee, prior to the giving of any notice of redemption to
Holders pursuant to this Section, an Officer's Certificate stating that such
restriction has been complied with.

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

                                                                            PAGE

part, to the portion of the principal amount of such Security which has been
or is to be redeemed.

      SECTION 12.03. 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 Issuer shall default in the payment of such Securities at the
redemption price, together with interest accrued to said date) interest on the
Securities or portions of Securities so called for redemption shall cease to
accrue, and the unmatured Coupons, if any, appertaining thereto shall be void,
and, except as provided in Sections 6.05 and 10.04, 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 Issuer at the applicable redemption price, together
with interest accrued thereon to the date fixed for redemption; provided that
payment of interest becoming due on or prior to the date fixed for redemption
shall be payable 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 Holders of such Registered Securities
registered as such on the relevant record date subject to the terms and
provisions of Sections 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 Issuer 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 Issuer shall
execute and the Trustee shall authenticate and deliver to or on the order of the
Holder thereof, at the expense of the Issuer, a new Security or Securities of
such
<PAGE>

                                                                            PAGE

series, of authorized denominations, in principal amount equal to the unredeemed
portion of the Security so presented.

      SECTION 12.04. 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 15 days
prior to the last date on which notice of redemption may be given as being owned
of record and beneficially by, and not pledged or hypothecated by either (a) the
Issuer or (b) an entity specifically identified in such written statement as
directly or indirectly controlling or controlled by or under direct or indirect
common control with the Issuer.

      SECTION 12.05. 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 is herein referred to as an "optional sinking fund
payment". The date on which a sinking fund payment is to be made is herein
referred to as the "sinking fund payment date".

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

      On or before the 60th day next preceding each sinking fund payment date or
the 30th day next preceding the last day of any applicable Redemption Notice
Period relating to a sinking fund payment date for any series, the Issuer will
deliver to the Trustee an Officer's Certificate (which need not contain the
statements required by Section 11.05) (a) specifying the portion of the
mandatory sinking fund payment to be satisfied by payment of cash and the
portion to be satisfied by credit of Securities of such series and the basis for
such credit, (b) stating that none of the Securities of such series has
theretofore been so credited,
<PAGE>

                                                                            PAGE
                                                                            ----

(c) stating that no defaults in the payment of interest or Events of Default
with respect to such series have occurred (which have not been waived or cured)
and are continuing and (d) stating whether or not the Issuer intends to exercise
its right to make an optional sinking fund payment with respect to such series
and, if so, specifying the amount of such optional sinking fund payment which
the Issuer intends to pay on or before the next succeeding sinking fund payment
date. Any Securities of such series to be credited and required to be delivered
to the Trustee in order for the Issuer to be entitled to credit therefor as
aforesaid which have not theretofore been delivered to the Trustee shall be
delivered for cancellation pursuant to Section 2.10 to the Trustee with such
Officer's Certificate (or reasonably promptly thereafter if acceptable to the
Trustee). Such Officer's Certificate shall be irrevocable and upon its receipt
by the Trustee the Issuer shall become unconditionally obligated to make all the
cash payments or payments therein referred to, if any, on or before the next
succeeding sinking fund payment date. Failure of the Issuer, on or before any
such 60th day or 30th day, if applicable, to deliver such Officer's Certificate
and Securities specified in this paragraph, if any, shall not constitute a
default but shall constitute, on and as of such date, the irrevocable election
of the Issuer (i) that the mandatory sinking fund payment for such series due on
the next succeeding sinking fund payment date shall be paid entirely in cash
without the option to deliver or credit Securities of such series in respect
thereof and (ii) that the Issuer will make no optional sinking fund payment with
respect to such series as provided in this Section.

      If the sinking fund payment or payments (mandatory or optional or both) to
be made in cash on the next succeeding sinking fund payment date plus any unused
balance of any preceding sinking fund payments made in cash shall exceed $50,000
(or the equivalent thereof in any Foreign Currency) or a lesser sum in Dollars
(or the equivalent thereof in any Foreign Currency) if the Issuer shall so
request with respect to the Securities of any particular series, such cash shall
be applied on the next succeeding sinking fund payment date to the redemption of
Securities of such series at the sinking fund redemption price together with
accrued interest to the date fixed for redemption. If such amount shall be
$50,000 (or the equivalent thereof in any Foreign Currency) or less and the
Issuer 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) is available. The
Trustee shall select, in the manner provided in Section 12.02, 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 Issuer) inform the Issuer of the serial numbers of the Securities
of such series (or portions thereof) so selected. Securities shall be excluded
from eligibility for redemption under this Section if they are identified by
registration and certificate number in an Officer's Certificate delivered to the
Trustee at least 60 days prior to the sinking fund payment date or at least 30
days prior to the last

payment date as being owned of record and beneficially by, and not pledged or
hypothecated by either (a) the Issuer or (b) an entity specifically identified
in such Officer's Certificate as directly or indirectly controlling or
controlled by or under direct or indirect common control with the Issuer. The
Trustee, in the name and at the expense of the Issuer (or the Issuer, if it
shall so request the Trustee in writing) shall cause notice of redemption of the
Securities of such series to be given in substantially the manner provided in
Section 12.02 (and with the effect provided in Section 12.03) for the redemption
of Securities of such series in part at the option of the Issuer. The amount of
any sinking fund payments not so applied or allocated to the redemption of
Securities of such series shall be added to the next cash sinking fund payment
for such series and, together with such payment, shall be applied in accordance
with the provisions of this Section. Any and all sinking fund moneys held on the
stated maturity date of the Securities of any particular series (or earlier, if
such maturity is accelerated), which are not held for the payment or redemption
of particular Securities of such series shall be applied, together with other
moneys, if necessary, sufficient for the purpose, to the payment of the
principal of, and interest on, the Securities of such series at maturity.

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

      The Trustee shall not redeem or cause to be redeemed any Securities of a
series with sinking fund moneys or give any notice of redemption of Securities
for such series by operation of the sinking fund during the continuance of a
default in payment of interest on such Securities or of any Event of Default
except that, where the giving of notice of redemption of any Securities shall
theretofore have been made, the Trustee shall redeem or cause to be redeemed
such Securities, provided that it shall have received from the Issuer a sum
sufficient for such redemption. Except as aforesaid, any moneys in the sinking
fund for such series at the time when any such default or Event of Default shall
occur, and any moneys thereafter paid into the sinking fund, shall, during the
continuance of such default or Event of Default, be deemed to have been
collected under Article 5 and held for the payment of all such Securities. In
case such Event of Default shall have been waived as provided in Section 5.10 or
the default cured on or before the 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 13
                                  SUBORDINATION

      SECTION 13.01. Agreement of Subordination. The Issuer covenants and
agrees, and each holder of a Security or Coupon issued hereunder by its
acceptance thereof likewise covenants and agrees, that all indebtedness
represented by the Securities and any Coupons shall be issued subject to the
provisions of this Article 13, and each Person holding any Security or Coupon,
whether upon original issue or upon registration of transfer, assignment or
exchange thereof, accepts and agrees to be bound by such provisions.

      The payment of the principal of, premium, if any, and interest on any
Security issued hereunder shall, to the extent and in the manner hereinafter set
forth, be subordinated and subject in right of payment to the prior payment in
full of all Senior Indebtedness, whether outstanding at the date of this
Indenture or thereafter incurred.

      No provision of this Article 13 shall prevent the occurrence of any
default or Event of Default hereunder.

      SECTION 13.02. Payments to Securityholders. No payment shall be made with
respect to the principal of premium, if any, or interest on the Securities or
any Coupons, except payments and distributions made by the Trustee as permitted
by the first or second paragraph of Section 13.05, if:

      (a) a default in the payment of principal, premium, if any, interest, rent
or other obligations in respect of Designated Senior Indebtedness occurs and is
continuing (or, in the case of Designated Senior Indebtedness for which there is
a period of grace, in the event of such a default that continues beyond the
period of grace, if any, specified in the instrument or lease evidencing such
Designated Senior Indebtedness) (a "Payment Default"), unless and until such
Payment Default shall have been cured or waived or shall have ceased to exist;
or

      (b) a default, other than a Payment Default, on any Designated Senior
Indebtedness occurs and is continuing that then permits holders of such
Designated Senior Indebtedness to accelerate its maturity (or in the case of any
lease, a default occurs and is continuing that permits the lessor to either
terminate the lease or require the Issuer to make an irrevocable offer to
terminate the lease following an event of default thereunder) and the Trustee
receives a notice of the default (a "Payment Blockage Notice") from a holder of
Designated Senior

Indebtedness, a Representative of Designated Senior Indebtedness or the Issuer
(a "Non-Payment Default").

      If the Trustee receives any Payment Blockage Notice pursuant to clause (b)
above, no subsequent Payment Blockage Notice shall be effective for purposes of
this Section 13.02 unless and until at least 365 days shall have elapsed since
the initial effectiveness of the immediately prior Payment Blockage Notice. No
Non-Payment Default that existed or was continuing on the date of delivery of
any Payment Blockage Notice to the Trustee shall be, or be made, the basis for a
subsequent Payment Blockage Notice.

      The Issuer may and shall resume payments on and distributions in respect
of the Securities and Coupons upon the earlier of:

      (i) the date upon which any such Payment Default is cured or waived or
ceases to exist, or

      (ii) in the case of a Non-Payment Default, the earlier of (a) the date
upon which such default is cured or waived or ceases to exist or (b) 179 days
after the applicable Payment Blockage Notice is received by the Trustee if the
maturity of such Designated Senior Indebtedness has not been accelerated (or in
the case of any lease, 179 days after notice is received if the Issuer has not
received notice that the lessor under such lease has exercised its right to
terminate the lease or require the Issuer to make an irrevocable offer to
terminate the lease following an event of default thereunder), unless this
Article 13 otherwise prohibits the payment or distribution at the time of such
payment or distribution.

      Upon any payment by the Issuer, or distribution of assets of the Issuer of
any kind or character, whether in cash, property or securities, to creditors
upon any dissolution or winding up or liquidation or reorganization of the
Issuer, whether voluntary or involuntary or in bankruptcy, insolvency,
receivership or other proceedings, all amounts due or to become due upon all
Senior Indebtedness shall first be paid in full in cash or other payment
satisfactory to the holders of such Senior Indebtedness (and satisfactory to the
holders of Senior Indebtedness in the case such Senior Indebtedness includes
Designated Senior Indebtedness), or payment thereof in accordance with its terms
provided for in cash or other payment satisfactory to the holders of such Senior
Indebtedness (and satisfactory to the holders of Senior Indebtedness in the case
such Senior Indebtedness includes Designated Senior Indebtedness) before any
payment is made on account of the principal of, premium, if any, or interest on
the Securities and any Coupons (except payments made pursuant to Article 10 from
monies deposited with the Trustee pursuant thereto prior to commencement of
proceedings for such dissolution, winding up, liquidation or reorganization),
and upon any such dissolution or winding up or liquidation or reorganization of
the Issuer or

bankruptcy, insolvency, receivership or other similar proceeding, any payment by
the Issuer, or distribution of assets of the Issuer of any kind or character,
whether in cash, property or securities, to which the holders of the Securities
and any Coupons or the Trustee would be entitled, except for the provisions of
this Article 13, shall (except as aforesaid) be paid by the Issuer or by any
receiver, trustee in bankruptcy, liquidating trustee, agent or other Person
making such payment or distribution, or by the holders of the Securities or any
Coupons or by the Trustee under this Indenture if received by them or it,
directly to the holders of Senior Indebtedness (pro rata to such holders on the
basis of the respective amounts of Senior Indebtedness held by such holders, or
as otherwise required by law or a court order) or their Representative or
Representatives, as their respective interests may appear, to the extent
necessary to pay all Senior Indebtedness in full, in cash or other payment
satisfactory to the holders of such Senior Indebtedness (and satisfactory to the
holders of Senior Indebtedness in the case such Senior Indebtedness includes
Designated Senior Indebtedness), after giving effect to any concurrent payment
or distribution to or for the holders of Senior Indebtedness, before any payment
or distribution is made to the holders of the Securities and any Coupons or to
the Trustee.

      For purposes of this Article 13, the words, "cash, property or securities"
shall not be deemed to include shares of stock of the Issuer as reorganized or
readjusted, or securities of the Issuer or any other corporation provided for by
a plan of reorganization or readjustment, the payment of which is subordinated
at least to the extent provided in this Article 13 with respect to the
Securities and any Coupons to the payment of all Senior Indebtedness which may
at the time be outstanding provided that (i) the Senior Indebtedness is assumed
by the new corporation, if any, resulting from any reorganization or
readjustment, and (ii) the rights of the holders of Senior Indebtedness (other
than leases which are not assumed by the Issuer or the new corporation, as the
case may be) are not, without the consent of such holders, altered by such
reorganization or readjustment. The consolidation of the Issuer with, or the
merger of the Issuer into, another corporation or the liquidation or dissolution
of the Issuer following the conveyance or transfer of its property as an
entirety, or substantially as an entirety, to another Person upon the terms and
conditions provided for in Article 9 shall not be deemed a dissolution,
winding-up, liquidation or reorganization for the purposes of this Section 13.02
if such other Person shall, as a part of such consolidation, merger, conveyance
or transfer, comply with the conditions stated in Article 9.

      In the event of the acceleration of the Securities because of an Event of
Default, no payment or distribution shall be made to the Trustee or any holder
of Securities or any Coupons in respect of the principal of, premium, if any, or
interest on the Securities and any Coupons, except payments and distributions

made by the Trustee as permitted by the first or second paragraph of Section
13.05, until all Senior Indebtedness has been paid in full in cash or other
payment satisfactory to the holders of Senior Indebtedness (and satisfactory to
the holders of Designated Senior Indebtedness in the case such Senior
Indebtedness includes Designated Senior Indebtedness) or such acceleration is
rescinded in accordance with the terms of this Indenture. If payment of the
Securities is accelerated because of an Event of Default, the Issuer or the
Trustee shall promptly notify holders of Senior Indebtedness of the
acceleration.

      In the event that, notwithstanding the foregoing provisions, any payment
or distribution of assets of the Issuer of any kind or character, whether in
cash, property or securities (including, without limitation, by way of setoff or
otherwise), prohibited by the foregoing provisions in this Section 13.02, shall
be received by the Trustee or the holders of the Securities or any Coupons
before all Senior Indebtedness is paid in full in cash or other payment
satisfactory to the holders of such Senior Indebtedness (and satisfactory to the
holders of Senior Indebtedness in the case such Senior Indebtedness includes
Designated Senior Indebtedness), or provision is made for such payment thereof
in accordance with its terms in cash or other payment satisfactory to the
holders of such Senior Indebtedness (and satisfactory to the holders of Senior
Indebtedness in the case such Senior Indebtedness includes Designated Senior
Indebtedness), such payment or distribution shall be held in trust for the
benefit of and shall be paid over or delivered to the holders of Senior
Indebtedness or their Representative or Representatives, as their respective
interests may appear, as calculated by the Issuer, for application to the
payment of any Senior Indebtedness remaining unpaid to the extent necessary to
pay all Senior Indebtedness in full in cash or other payment satisfactory to the
holders of such Senior Indebtedness (and satisfactory to the holders of Senior
Indebtedness in the case such Senior Indebtedness includes Designated Senior
Indebtedness), after giving effect to any concurrent payment or distribution to
or for the holders of such Senior Indebtedness.

      Nothing in this Section 13.02 shall apply to claims of, or payments to,
the Trustee under or pursuant to Section 6.06. This Section 13.02 shall be
subject to the further provisions of Section 13.05.

      SECTION 13.03. Subrogation. Subject to the payment in full of all Senior
Indebtedness, the rights of the holders of the Securities and any Coupons shall
be subrogated to the extent of the payments or distributions made to the holders
of such Senior Indebtedness pursuant to the provisions of this Article 13
(equally and ratably with the holders of all indebtedness of the Issuer which by
its express terms is subordinated to other indebtedness of the Issuer to
substantially the same extent as the Securities and any Coupons are subordinated
and is entitled to like

rights of subrogation) to the rights of the holders of Senior Indebtedness to
receive payments or distributions of cash, property or securities of the Issuer
applicable to the Senior Indebtedness until the principal, premium, if any, and
interest on the Securities and any Coupons shall be paid in full, and, for the
purposes of such subrogation, no payments or distributions to the holders of the
Senior Indebtedness of any cash, property or securities to which the holders of
the Securities and any Coupons or the Trustee would be entitled except for the
provisions of this Article 13, and no payment pursuant to the provisions of this
Article 13, to or for the benefit of the holders of Senior Indebtedness by
holders of the Securities and any Coupons or the Trustee, shall, as among the
Issuer, its creditors other than holders of Senior Indebtedness, and the holders
of the Securities and any Coupons, be deemed to be a payment by the Issuer to or
on account of the Senior Indebtedness, and no payments or distributions of cash,
property or securities to or for the benefit of the holders of the Securities
and any Coupons pursuant to the subrogation provisions of this Article 13, which
would otherwise have been paid to the holders of Senior Indebtedness, shall be
deemed to be a payment by the Issuer to or for the account of the Securities and
any Coupons. It is understood that the provisions of this Article 13 are
intended solely for the purposes of defining the relative rights of the holders
of the Securities and any Coupons, on the one hand, and the holders of the
Senior Indebtedness, on the other hand.

      Nothing contained in this Article 13 or elsewhere in this Indenture or in
the Securities or any Coupons is intended to or shall impair, as among the
Issuer, its creditors other than the holders of Senior Indebtedness, and the
holders of the Securities or any Coupons, the obligation of the Issuer, which is
absolute and unconditional, to pay to the holders of the Securities and any
Coupons the principal of, premium, if any, and interest on the Securities and
any Coupons as and when the same shall become due and payable in accordance with
their terms, or is intended to or shall affect the relative rights of the
holders of the Securities or any Coupons and creditors of the Issuer other than
the holders of the Senior Indebtedness, nor shall anything herein or therein
prevent the Trustee or the holder of any Security or Coupon from exercising all
remedies otherwise permitted by applicable law upon default under this
Indenture, subject to the rights, if any, under this Article 13 of the holders
of Senior Indebtedness in respect of cash, property or securities of the Issuer
received upon the exercise of any such remedy.

      Upon any payment or distribution of assets of the Issuer referred to in
this Article 13, the Trustee, subject to the provisions of Section 6.01, and the
holders of the Securities or any Coupons shall be entitled to rely upon any
order or decree made by any court of competent jurisdiction in which such
bankruptcy, dissolution, winding up, liquidation or reorganization proceedings
are pending, or a certificate

of the receiver, trustee in bankruptcy, liquidating trustee, agent or other
Person making such payment or distribution, delivered to the Trustee or to the
holders of the Securities or any Coupons, for the purpose of ascertaining the
Persons entitled to participate in such distribution, the holders of the Senior
Indebtedness and other indebtedness of the Issuer, the amount thereof or payable
thereon and all other facts pertinent thereto or to this Article 13.

      SECTION 13.04. Authorization to Effect Subordination. Each holder of a
Security or any Coupon by the holder's acceptance thereof authorizes and directs
the Trustee on the holder's behalf to take such action as may be necessary or
appropriate to effectuate the subordination as provided in this Article 13 and
appoints the Trustee to act as the holder's attorney-in-fact for any and all
such purposes. If the Trustee does not file a proper proof of claim or proof of
debt in the form required in any proceeding referred to in the third paragraph
of Section 5.02 hereof at least thirty (30) days before the expiration of the
time to file such claim, the holders of any Senior Indebtedness or their
Representatives are hereby authorized to file an appropriate claim for and on
behalf of the holders of the Securities and any Coupon.

      SECTION 13.05. Notice to Trustee. The Issuer shall give prompt written
notice in the form of an Officers' Certificate to a Responsible Officer of the
Trustee and to any paying agent of any fact known to the Issuer that would
prohibit the making of any payment of monies to or by the Trustee or any paying
agent in respect of the Securities or any Coupon pursuant to the provisions of
this Article 13. Notwithstanding the provisions of this Article 13 or any other
provision of this Indenture, the Trustee shall not be charged with knowledge of
the existence of any facts that would prohibit the making of any payment of
monies to or by the Trustee in respect of the Securities or any Coupon pursuant
to the provisions of this Article 13, unless and until a Responsible Officer of
the Trustee shall have received written notice thereof at the Corporate Trust
Office from the Issuer (in the form of an Officer's Certificate) or a
Representative or a holder or holders of Senior Indebtedness, and before the
receipt of any such written notice, the Trustee, subject to the provisions of
Section 6.01, shall be entitled in all respects to assume that no such facts
exist; provided, however, that if on a date not less than one Business Day prior
to the date upon which by the terms hereof any such monies may become payable
for any purpose (including, without limitation, the payment of the principal of,
or premium, if any, or interest on any Security or Coupon) the Trustee shall not
have received, with respect to such monies, the notice provided for in this
Section 13.05, then, anything herein contained to the contrary notwithstanding,
the Trustee shall have full power and authority to apply monies received to the
purpose for which they were received, and shall not be affected by any notice to
the contrary that may be received by it on or after such prior date.

                                                                            PAGE

      Notwithstanding anything in this Article 13 to the contrary, nothing shall
prevent any payment by the Trustee to the Securityholders of monies deposited
with it pursuant to Section 10.01, if a Responsible Officer of the Trustee shall
not have received written notice at the Corporate Trust Office on or before one
Business Day prior to the date such payment is due that such payment is not
permitted under Section 13.01 or 13.02.

      The Trustee, subject to the provisions of Section 6.01, shall be entitled
to rely on the delivery to it of a written notice by a Representative or a
person representing himself to be a holder of Senior Indebtedness (or a trustee
on behalf of such holder) to establish that such notice has been given by a
Representative or a holder of Senior Indebtedness or a trustee on behalf of any
such holder or holders. The Trustee shall not be required to make any payment or
distribution to or on behalf of a holder of Senior Indebtedness pursuant to this
Article 13 unless it has received satisfactory evidence as to the amount of
Senior Indebtedness held by such Person, the extent to which such Person is
entitled to participate in such payment or distribution and any other facts
pertinent to the rights of such Person under this Article 13.

      SECTION 13.06. Trustee's Relation to Senior Indebtedness. The Trustee, in
its individual capacity, shall be entitled to all the rights set forth in this
Article 13 in respect of any Senior Indebtedness at any time held by it, to the
same extent as any other holder of Senior Indebtedness, and nothing in Section
6.13 or elsewhere in this Indenture shall deprive the Trustee of any of its
rights as such holder.

      With respect to the holders of Senior Indebtedness, the Trustee undertakes
to perform or to observe only such of its covenants and obligations as are
specifically set forth in this Article 13, and no implied covenants or
obligations with respect to the holders of Senior Indebtedness shall be read
into this Indenture against the Trustee. The Trustee shall not be deemed to owe
any fiduciary duty to the holders of Senior Indebtedness and, subject to the
provisions of Section 6.01, the Trustee shall not be liable to any holder of
Senior Indebtedness (i) for any failure to make any payments or distributions to
such holder or (ii) if it shall pay over or deliver to holders of Securities or
any Coupon, the Issuer or any other Person money in compliance with this Article
13.

      SECTION 13.07. No Impairment of Subordination. No right of any present or
future holder of any Senior Indebtedness to enforce subordination as herein
provided shall at anytime in any way be prejudiced or impaired by any act or
failure to act on the part of the Issuer or by any act or failure to act, in
good faith, by any such holder, or by any noncompliance by the Issuer with the
terms, provisions and covenants of this Indenture, regardless of any knowledge
thereof which any such holder may have or otherwise be charged with. Senior

Indebtedness may be created, renewed, refinanced, replaced, deferred, refunded,
amended, modified, supplemented or extended and holders of Senior Indebtedness
may exercise any rights under any instrument creating or evidencing such Senior
Indebtedness, including, without limitation, any waiver of default thereunder,
without any notice to or consent from the holders of the Securities or any
Coupon or the Trustee. No compromise, alteration, amendment, modification,
extension, renewal or other change of or waiver, consent or other action in
respect of, any liability or obligation under or in respect of the Senior
Indebtedness or any terms or conditions of any instrument creating or evidencing
such Senior Indebtedness shall in any way alter or affect any of the provisions
of this Article 13 or the subordination of the Securities and Coupons provided
thereby.

      SECTION 13.08. Article Applicable to Paying Agents. If at any time any
paying agent other than the Trustee shall have been appointed by the Issuer and
be then acting hereunder, the term "Trustee" as used in this Article 13 shall
(unless the context otherwise requires) be construed as extending to and
including such paying agent within its meaning as fully for all intents and
purposes as if such paying agent were named in this Article 13 in addition to or
in place of the Trustee; provided, however, that the first paragraph of Section
13.05 shall not apply to the Issuer or any affiliate of the Issuer if it or such
affiliate acts as paying agent.

      The Trustee shall not be responsible for the actions or inactions of any
other paying agents (including the Issuer if acting as its own paying agent) and
shall have no control of any funds held by such other paying agents.

      SECTION 13.09. Senior Indebtedness Entitled to Rely. The holders of Senior
Indebtedness (including, without limitation, Designated Senior Indebtedness)
shall have the right to rely upon this Article 13, and no amendment or
modification of the provisions contained herein shall diminish the rights of
such holders unless such holders shall have agreed in writing thereto.

      SECTION 13.10. Reliance on Judicial Order or Certificate of Liquidating
Agent. Upon any payment or distribution of assets of the Issuer referred to in
this Article 13, the Trustee and the Securityholders shall be entitled to rely
upon any order or decree entered by any court of competent jurisdiction in which
such insolvency, bankruptcy, receivership, liquidation, reorganization,
dissolution, winding up or similar case or proceeding is pending, or a
certificate of the trustee in bankruptcy, liquidating trustee, custodian,
receiver, assignee for the benefit of creditors, agent or other Person making
such payment or distribution, delivered to the Trustee or to the
Securityholders, for the purpose of ascertaining the Persons entitled to
participate in such payment or distribution, the holders of Senior Indebtedness
