tenor and purport as set forth in one or more indentures supplemental hereto or
as provided in a Board Resolution of the Company and as set forth in an
Officers' Certificate of the Company and may have such letters, numbers or other
marks of identification or designation and such legends or endorsements printed,
lithographed or engraved thereon as the Company may deem appropriate and as are
not inconsistent with the provisions of this Indenture, or as may be required to
comply with any law or with any rule or regulation made pursuant thereto or with
any rule or regulation of any stock exchange on which Securities of that series
may be listed, or to conform to usage.

Section 2.03   Denominations:  Provisions for Payment.
               --------------------------------------

     The Securities shall be issuable as registered Securities and in the
denominations of One Thousand U.S. Dollars ($1,000) or any integral multiple
thereof, subject to Section 2.01(10). The Securities of a particular series
shall bear interest payable on the dates and at the rate specified as provided
in Section 2.01 with respect to that series. The principal of and the interest
on the Securities of any series, as well as any premium thereon in case of
redemption thereof prior to maturity, shall be payable in the coin or currency
of the United States of America that at the time is legal tender for public and
private debt, at the office or agency of the Company maintained for that purpose
in the Borough of Manhattan, the City and State of New York. Each Security shall
be dated the date of its authentication. Unless otherwise specified with respect
to a series of Securities in accordance with the provisions of Section 2.01,
interest on the Securities shall be computed on the basis of a 360-day year
composed of twelve 30-day months.

     The interest installment on any Security that is payable, and is punctually
paid or duly provided for, on any Interest Payment Date for Securities of that
series shall be paid to the Person in whose name said Security (or one or more
Predecessor Securities) is registered at the close of business on the regular
record date for such interest installment. In the event that any Security of a
particular series or portion thereof is called for redemption and the redemption
date is subsequent to a regular record date with respect to any Interest Payment
Date and prior to such Interest Payment Date, interest on such Security will be
paid upon presentation and surrender of such Security as provided in Section
3.03.

     Unless otherwise specified with respect to a series of Securities in
accordance with the provisions of Section 2.01, any interest on any Security
that is payable, but is not punctually paid or duly provided for, on any
Interest Payment Date for Securities of the same series (herein called
"Defaulted Interest") shall forthwith cease to be payable to the registered
holder on the relevant regular record date and such Defaulted Interest shall be
paid by the Company, at its election, as provided in clause (1) or clause (2)
below.

                                       7
<PAGE>

          (1)  The Company may make payment of any Defaulted Interest on
     Securities to the Persons in whose names such Securities (or their
     respective Predecessor Securities) are registered at the close of business
     on a special record date for the payment of such Defaulted Interest, which
     shall be fixed in the following manner:  the Company shall notify the
     Trustee in writing of the amount of Defaulted Interest proposed to be paid
     on each such Security and the date of the proposed payment, and at the same
     time the Company shall deposit with the Trustee an amount of money equal to
     the aggregate amount proposed to be paid in respect of such Defaulted
     Interest or shall make arrangements satisfactory to the Trustee for such
     deposit prior to the date of the proposed payment, such money when
     deposited to be held in trust for the benefit of the Persons entitled to
     such Defaulted Interest as in this clause (1) provided.  Thereupon the
     Trustee shall fix a special record date for the payment of such Defaulted
     Interest which shall not be more than 15 nor less than 10 days prior to the
     date of the proposed payment and not less than 10 days after the receipt by
     the Trustee of the notice of the proposed payment.  The Trustee shall
     promptly notify the Company of such special record date and, in the name
     and at the expense of the Company, shall cause notice of the proposed
     payment of such Defaulted Interest and the special record date therefor to
     be mailed, first class postage prepaid, to each Securityholder at his or
     her address as it appears in the Security Register (as hereinafter
     defined), not less than 10 days prior to such special record date.  Notice
     of the proposed payment of such Defaulted Interest and the special record
     date therefor having been mailed as aforesaid, such Defaulted Interest
     shall be paid to the Persons in whose names such Securities (or their
     respective Predecessor Securities) are registered on such special record
     date and shall not be payable pursuant to the following clause (2).

          (2)  The Company may make payment of any Defaulted Interest on any
     Securities in any other lawful manner not inconsistent with the
     requirements of any securities exchange on which such Securities may be
     listed, and upon such notice as may be required by such exchange.

     Unless otherwise set forth in a Board Resolution of the Company or one or
more indentures supplemental hereto establishing the terms of any series of
Securities pursuant to Section 2.01 hereof, the term "regular record date" as
used in this Section with respect to a series of Securities with respect to any
Interest Payment Date for such series shall mean either the fifteenth day of the
month immediately preceding the month in which an Interest Payment Date
established for such series pursuant to Section 2.01 hereof shall occur, if such
Interest Payment Date is the first day of a month, or the last day of the month
immediately preceding the month in which an Interest Payment Date established
for such series pursuant to Section 2.01 hereof shall occur, if such Interest
Payment Date is the fifteenth day of a month, whether or not such date is a
Business Day. Subject to the foregoing provisions of this Section, each Security
of a series delivered under this Indenture upon transfer of or in exchange for
or in lieu of any other Security of such series shall carry the rights to
interest accrued and unpaid, and to accrue, that were carried by such other
Security.

                                       8

Section 2.04   Execution and Authentications.
               -----------------------------

     The Securities shall be signed on behalf of the Company by two Officers.
Signatures may be in the form of a manual or facsimile signature.  The Company
may use the facsimile signature of any Person who shall have been an Officer,
notwithstanding the fact that at the time the Securities shall be authenticated
and delivered or disposed of such Person shall have ceased to be an Officer of
the Company.  The Securities may contain such notations, legends or endorsements
required by law, stock exchange rule or usage.  Each Security shall be dated the
date of its authentication by the Trustee.

     A Security shall not be valid until authenticated manually by an authorized
signatory of the Trustee or by an Authenticating Agent.  Such signature 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.  At any time and from time to time after the
execution and delivery of this Indenture, the Company may deliver Securities of
any series executed by the Company to the Trustee for authentication, together
with a written order of the Company for the authentication and delivery of such
Securities, signed by an Officer, and the Trustee in accordance with such
written order shall authenticate and deliver such Securities.

Section 2.05   Registration of Transfer and Exchange.
               -------------------------------------

     (a)       Securities of any series may be exchanged upon presentation
thereof at the office or agency of the Company designated for such purpose in
the Borough of Manhattan, the City and State of New York, for other Securities
of such series of authorized denominations, and for a like aggregate principal
amount, upon payment of a sum sufficient to cover any tax or other governmental
charge in relation thereto, all as provided in this Section 2.05. In respect of
any Securities so surrendered for exchange, the Company shall execute, the
Trustee shall authenticate and such office or agency shall deliver in exchange
therefor the Security or Securities of the same series that the Securityholder
making the exchange shall be entitled to receive, bearing numbers not
contemporaneously outstanding.

     (b)       The Company shall keep, or cause to be kept, at its office or
agency designated for such purpose in the Borough of Manhattan, the City and
State of New York, or such other location designated by the Company a register
or registers (herein referred to as the "Security Register") in which, subject
                                         -----------------
to such reasonable regulations as it may prescribe, the Company shall register
the Securities and the transfers of Securities as in this Article II provided
and which at all reasonable times shall be open for inspection by the Trustee.
The registrar for the purpose of registering Securities and transfer of
Securities as herein provided shall be appointed as authorized by Board
Resolution (the "Security Registrar"). If the Company fails to appoint or
                 ------------------
maintain another entity as Security Registrar, the Trustee shall act as such.
The Company or any of its Subsidiaries may act as Security Registrar.

     Upon surrender for transfer of any Security at the office or agency of the
Company designated for such purpose, the Company shall execute, the Trustee
shall authenticate and such office or agency shall deliver in the name of the
transferee or transferees a new Security or Securities of the same series as the
Security presented for a like aggregate principal amount.

                                       9
<PAGE>

     All Securities presented or surrendered for exchange or registration of
transfer, as provided in this Section 2.05, shall be accompanied (if so required
by the Company or the Security Registrar) by a written instrument or instruments
of transfer, in form satisfactory to the Company or the Security Registrar, duly
executed by the registered holder or by such holder's duly authorized attorney
in writing.

     (c)       No service charge shall be made for any exchange or registration
of transfer of Securities, or issue of new Securities in case of partial
redemption of any series, but the Company may require payment of a sum
sufficient to cover any tax or other governmental charge in relation thereto,
other than exchanges pursuant to Section 2.06, Section 3.03(b) and Section 9.04
not involving any transfer.

     (d)       The Company shall not be required (i) to issue, exchange or
register the transfer of any Securities during a period beginning at the opening
of business 15 days before the day of the mailing of a notice of redemption of
less than all the Outstanding Securities of the same series and ending at the
close of business on the day of such mailing, nor (ii) to register the transfer
of or exchange any Securities of any series or portions thereof called for
redemption. The provisions of this Section 2.05 are, with respect to any Global
Security, subject to Section 2.11 hereof.

Section 2.06   Temporary Securities.
               --------------------

     Pending the preparation of definitive Securities of any series, the Company
may execute, and the Trustee shall authenticate and deliver, temporary
Securities (printed, lithographed or typewritten) of any authorized
denomination.  Such temporary Securities shall be substantially in the form of
the definitive Securities in lieu of which they are issued, but with such
omissions, insertions and variations as may be appropriate for temporary
Securities, all as may be determined by the Company.  Every temporary Security
of any series shall be executed by the Company and be authenticated by the
Trustee upon the same conditions and in substantially the same manner, and with
like effect, as the definitive Securities of such series.  Without unnecessary
delay the Company will execute and will furnish definitive Securities of such
series and thereupon any or all temporary Securities of such series may be
surrendered in exchange therefor (without charge to the holders), at the office
or agency of the Company designated for the purpose in the Borough of Manhattan,
the City and State of New York, and the Trustee shall authenticate and such
office or agency shall deliver in exchange for such temporary Securities an
equal aggregate principal amount of definitive Securities of such series, unless
the Company advises the Trustee to the effect that definitive Securities need
not be executed and furnished until further notice from the Company.  Until so
exchanged, the temporary Securities of such series shall be entitled to the same
benefits under this Indenture as definitive Securities of such series
authenticated and delivered hereunder.

Section 2.07   Mutilated, Destroyed, Lost or Stolen Securities.
               ----------------------------------------------

     In case any temporary or definitive Security shall become mutilated or be
destroyed, lost or stolen, the Company (subject to the next succeeding sentence)
shall execute, and upon the Company's request the Trustee (subject to the next
succeeding sentence) shall authenticate and deliver, a new Security of the same
series, bearing a number not contemporaneously outstanding,

                                      10
<PAGE>

in exchange and substitution for the mutilated Security, or in lieu of and in
substitution for the Security so destroyed, lost or stolen. In every case the
applicant for a substituted Security shall furnish to the Company and the
Trustee such security or indemnity as may be required by them to save each of
them harmless, and, in every case of destruction, loss or theft, the applicant
shall also furnish to the Company and the Trustee evidence to their satisfaction
of the destruction, loss or theft of the applicant's Security and of the
ownership thereof. The Trustee may authenticate any such substituted Security
and deliver the same upon the written request or authorization of any Officer.
Upon the issuance of any substituted Security, the Company may require the
payment of a sum sufficient to cover any tax or other governmental charge that
may be imposed in relation thereto and any other expenses (including the fees
and expenses of the Trustee) connected therewith. In case any Security that has
matured or is about to mature shall become mutilated or be destroyed, lost or
stolen, the Company may, instead of issuing a substitute Security, pay or
authorize the payment of the same (without surrender thereof except in the case
of a mutilated Security) if the applicant for such payment shall furnish to the
Company and the Trustee such security or indemnity as they may require to save
them harmless, and, in case of destruction, loss or theft, evidence to the
satisfaction of the Company and the Trustee of the destruction, loss or theft of
such Security and of the ownership thereof.

     Every replacement Security issued pursuant to the provisions of this
Section 2.07 shall constitute an additional contractual obligation of the
Company whether or not the mutilated, destroyed, lost or stolen Security shall
be found at any time, or be enforceable by anyone, and shall be entitled to all
the benefits of this Indenture equally and proportionately with any and all
other Securities of the same series duly issued hereunder. All Securities shall
be held and owned upon the express condition that the foregoing provisions are
exclusive with respect to the replacement or payment of mutilated, destroyed,
lost or stolen Securities, and shall preclude (to the extent lawful) 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 2.08   Cancellation.
               ------------

     All Securities surrendered for the purpose of payment, redemption, exchange
or registration of transfer shall, if surrendered to the Company or any paying
agent, be delivered to the Trustee for cancellation, or, if surrendered to the
Trustee, shall be cancelled by it, and no Securities shall be issued in lieu
thereof except as expressly required or permitted by any of the provisions of
this Indenture. On written request of the Company at the time of such surrender,
the Trustee shall deliver to the Company canceled Securities held by the
Trustee. In the absence of such request the Trustee may dispose of canceled
Securities in accordance with its standard procedures and deliver a certificate
of disposition to the Company. If the Company shall otherwise acquire any of the
Securities, however, such acquisition shall not operate as a redemption or
satisfaction of the indebtedness represented by such Securities unless and until
the same are delivered to the Trustee for cancellation.

Section 2.09   Benefits of Indenture.
               ---------------------

     Nothing in this Indenture or in the Securities, express or implied, shall
give or be construed to give to any Person, other than the parties hereto and
the holders of the Securities

                                      11
<PAGE>

(and the holders of unsubordinated indebtedness of the Company to the extent
necessary to give effect to the subordination provisions referred to in Article
XIV) any legal or equitable right, remedy or claim under or in respect of this
Indenture, or under any covenant, condition or provision herein contained; all
such covenants, conditions and provisions being for the sole benefit of the
parties hereto and of the holders of the Securities (and the holders of
unsubordinated indebtedness of the Company to the extent necessary to give
effect to the subordination provisions referred to in Article XIV).

Section 2.10   Authenticating Agent.
               --------------------

          So long as any of the Securities of any series remain Outstanding
there may be an Authenticating Agent for any or all such series of Securities
which the Trustee shall have the right to appoint. Said Authenticating Agent
shall be authorized to act on behalf of the Trustee to authenticate Securities
of such series, including Securities issued upon exchange, transfer or partial
redemption thereof, and Securities so authenticated shall be entitled to the
benefits of this Indenture and shall be valid and obligatory for all purposes as
if authenticated by the Trustee hereunder. All references in this Indenture to
the authentication of Securities by the Trustee shall be deemed to include
authentication by an Authenticating Agent for such series. Each Authenticating
Agent shall be acceptable to the Company and shall be a corporation that has a
combined capital and surplus, as most recently reported or determined by it,
sufficient under the laws of any jurisdiction under which it is organized or in
which it is doing business to conduct a trust business, and that is otherwise
authorized under such laws to conduct such business and is subject to
supervision or examination by Federal or State authorities. If at any time any
Authenticating Agent shall cease to be eligible in accordance with these
provisions, it shall resign immediately. Any Authenticating Agent may at any
time resign by giving written notice of resignation to the Trustee and to the
Company. The Trustee may at any time (and upon request by the Company shall)
terminate the agency of any Authenticating Agent by giving written notice of
termination to such Authenticating Agent and to the Company. Upon resignation,
termination or cessation of eligibility of any Authenticating Agent, the Trustee
may appoint an eligible successor Authenticating Agent acceptable to the
Company. Any successor Authenticating Agent, upon acceptance of its appointment
hereunder, shall become vested with all the rights, powers and duties of its
predecessor hereunder as if originally named as an Authenticating Agent pursuant
hereto.

Section 2.11   Global Securities.
               -----------------

          (a)  If the Company shall establish pursuant to Section 2.01 that the
Securities of a particular series are to be issued as a Global Security, then
the Company shall execute and the Trustee shall, in accordance with Section
2.04, authenticate, a Global Security that (i) shall represent, and shall be
denominated in an amount equal to the aggregate principal amount of, all of the
Outstanding Securities of such series, (ii) shall be registered in the name of
the Depositary or its nominee, (iii) shall be delivered to the Trustee as
custodian for the Depositary or otherwise delivered pursuant to the Depositary's
instruction and (iv) shall bear a legend substantially to the following effect:
"Except as otherwise provided in Section 2.11 of the Indenture, this Security
may be transferred, in whole but not in part, only to another nominee of the
Depositary or to a successor Depositary or to a nominee of such successor
Depositary."

                                      12
<PAGE>

          (b)  Notwithstanding the provisions of Section 2.05, the Global
Security of a series may be transferred, in whole but not in part and in the
manner provided in Section 2.05, only to another nominee of the Depositary for
such series, or to a successor Depositary for such series selected or approved
by the Company or to a nominee of such successor Depositary.

          (c)  If at any time the Depositary for a series of the Securities
notifies the Company that it is unwilling or unable to continue as Depositary
for such series or if at any time the Depositary for such series shall no longer
be registered or in good standing under the Exchange Act, or other applicable
statute or regulation, and a successor Depositary for such series is not
appointed by the Company within 90 days after the Company receives such notice
or becomes aware of such condition, as the case may be, this Section 2.11 shall
no longer be applicable to the Securities of such series and the Company will
execute, and subject to Section 2.05, the Trustee will authenticate and deliver
the Securities of such series in definitive registered form without coupons, in
authorized denominations, and in an aggregate principal amount equal to the
principal amount of the Global Security of such series in exchange for such
Global Security. In addition, the Company may at any time determine that the
Securities of any series shall no longer be represented by a Global Security and
that the provisions of this Section 2.11 shall no longer apply to the Securities
of such series. In such event the Company will execute and subject to Section
2.05, the Trustee, upon receipt of an Officers' Certificate evidencing such
determination by the Company, will authenticate and deliver the Securities of
such series in definitive registered form without coupons, in authorized
denominations, and in an aggregate principal amount equal to the principal
amount of the Global Security of such series in exchange for such Global
Security. Upon the exchange of the Global Security of such series for such
Securities of such series in definitive registered form without coupons, in
authorized denominations, the Global Security shall be canceled by the Trustee.
Such Securities of such series in definitive registered form issued in exchange
for the Global Security pursuant to this Section 2.11(c) shall be registered in
such names and in such authorized denominations as the Depositary, pursuant to
instructions from its direct or indirect participants or otherwise, shall
instruct the Trustee. The Trustee shall deliver such Securities to the
Depositary for delivery to the Persons in whose names such Securities are so
registered.

Section 2.12   CUSIP Numbers.
               -------------

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

             REDEMPTION OF SECURITIES AND SINKING FUND PROVISIONS

Section 3.01  Redemption.
              ----------

     The Company may redeem the Securities of any series issued hereunder on and
after the dates and in accordance with the terms established for such series
pursuant to Section 2.01 hereof.

Section 3.02  Notice of Redemption.
              --------------------

     (a)  If the Company desires to exercise such right to redeem all or, as the
case may be, a portion of the Securities of any series, the Company shall, or
shall cause the Trustee to, give notice of such redemption to holders of the
Securities of such series to be redeemed by mailing, first class postage
prepaid, a notice of such redemption not less than 30 days and not more than 90
days before the date fixed for redemption of that series to such holders at
their last addresses as they shall appear upon the Security Register (unless a
shorter period is specified in the Securities to be redeemed).  Any notice that
is mailed in the manner herein provided shall be conclusively presumed to have
been duly given, whether or not the registered holder receives the notice.  In
any case, failure duly to give such notice to the holder of any Security of any
series designated for redemption in whole or in part, or any defect in the
notice, shall not affect the validity of the proceedings for the redemption of
any other Securities of such series or any other series.  In the case of any
redemption of Securities prior to the expiration of any restriction on such
redemption provided in the terms of such Securities or elsewhere in this
Indenture, the Company shall furnish the Trustee with an Officers' Certificate
evidencing compliance with any such restriction.

     Each such notice of redemption shall specify the date fixed for redemption
and the redemption price at which Securities of that series are to be redeemed,
and shall state that payment of the redemption price of such Securities to be
redeemed will be made at the office or agency of the Company in the Borough of
Manhattan, the City and State of New York, upon presentation and surrender of
such Securities, that interest accrued to the date fixed for redemption will be
paid as specified in said notice, that from and after said date interest will
cease to accrue and that the redemption is for a sinking fund, if such is the
case.  If less than all the Securities of a series are to be redeemed, the
notice to the holders of Securities of that series to be redeemed in whole or in
part shall specify the particular Securities to be so redeemed.  In case any
Security is to be redeemed in part only, the notice that relates to such
Security shall state the portion of the principal amount thereof to be redeemed,
and shall state that on and after the redemption date, 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.

     (b)  If less than all the Securities of a series are to be redeemed, the
Company shall give the Trustee at least 45 days' notice in advance of the date
fixed for redemption as to the aggregate principal amount of Securities of the
series to be redeemed, and thereupon the Trustee shall select from Securities of
such series Outstanding not previously called for redemption, in accordance with
a method that it shall deem appropriate and fair (in such manner as complies

                                      14
<PAGE>

with applicable legal and stock exchange requirements, if any) and that may
provide for the selection of a portion or portions (equal to One Thousand U.S.
Dollars ($1,000) or any integral multiple thereof) of the principal amount of
such Securities of such series of a denomination larger than $1,000, the
Securities of such series to be redeemed and shall thereafter promptly notify
the Company in writing of the numbers of the Securities of such series to be
redeemed, in whole or in part.

     The Company may, if and whenever it shall so elect, by delivery of
instructions signed on its behalf by any of its Officers, instruct the Trustee
or any paying agent to call all or any part of the Securities of a particular
series for redemption and to give notice of redemption in the manner set forth
in this Section 3.02, such notice to be in the name of the Company or its own
name, as the Trustee or such paying agent may deem advisable.  In any case in
which notice of redemption is to be given by the Trustee or any such paying
agent, the Company shall deliver or cause to be delivered to, or permit to
remain with, the Trustee or such paying agent, as the case may be, such Security
Register, transfer books or other records, or suitable copies or extracts
therefrom, sufficient to enable the Trustee or such paying agent to give any
notice by mail that may be required under the provisions of this Section 3.02.

Section 3.03  Payment Upon Redemption.
              -----------------------

     (a)  If the giving of notice of redemption shall have been completed as
above provided, the Securities or portions of Securities of the series to be
redeemed 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, in each case as
established pursuant to Section 2.01, and interest on such Securities or
portions of Securities shall cease to accrue on and after the date fixed for
redemption, unless the Company shall default in the payment of such redemption
price and accrued interest with respect to any such Security or portion thereof.
On presentation and surrender of such Securities on or after the date fixed for
redemption at the place of payment specified in the notice, said Securities
shall be paid and redeemed at the applicable redemption price for such series,
together with interest accrued thereon to the date fixed for redemption (but if
the date fixed for redemption is an interest payment date, the interest
installment payable on such date shall be payable to the registered holder at
the close of business on the applicable record date pursuant to Section 2.03).

     (b)  Upon presentation of any Security of such series that is to be
redeemed in part only, the Company shall execute and the Trustee shall
authenticate and the office or agency where the Security is presented shall
deliver to the holder thereof, at the expense of the Company, a new Security of
the same series of authorized denominations in principal amount equal to the
unredeemed portion of the Security so presented.

Section 3.04  Sinking Fund.
              ------------

     The provisions of Sections 3.04, 3.05 and 3.06 shall be applicable to any
sinking fund for the retirement of Securities of a series, except as otherwise
specified as contemplated by Section 2.01 for Securities of such series.

                                      15
<PAGE>

     The minimum amount of any sinking fund payment provided for by the terms of
Securities of any series is herein referred to as a "mandatory sinking fund
payment," and any payment in excess of such minimum amount provided for by the
terms of Securities of any series is herein referred to as an "optional sinking
fund payment".  If provided for by the terms of Securities of any series, the
cash amount of any sinking fund payment may be subject to reduction as provided
in Section 3.05.  Each sinking fund payment shall be applied to the redemption
of Securities of any series as provided for by the terms of Securities of such
series.

Section 3.05  Satisfaction of Sinking Fund Payments with Securities.
              -----------------------------------------------------

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

Section 3.06  Redemption of Securities for Sinking Fund.
              -----------------------------------------

     Not less than 45 days prior to each sinking fund payment date for any
series of Securities, the Company will deliver to the Trustee an Officers'
Certificate specifying the amount of the next ensuing sinking fund payment for
that series pursuant to the terms of the series, the portion thereof, if any,
that is to be satisfied by delivering and crediting Securities of that series
pursuant to Section 3.05 and the basis for such credit and will, together with
such Officers' Certificate, deliver to the Trustee any Securities to be so
delivered.  Not less than 30 days before each such sinking fund payment date the
Trustee shall select the Securities to be redeemed upon such sinking fund
payment date in the manner specified in Section 3.02 and cause notice of the
redemption thereof to be given in the name of and at the expense of the Company
in the manner provided in Section 3.02.  Such notice having been duly given, the
redemption of such Securities shall be made upon the terms and in the manner
stated in Section 3.03.

                                  ARTICLE IV.

                               CERTAIN COVENANTS

              ------------------------------------------

and place and in the manner provided herein and established with respect to such
Securities.

<PAGE>

Section 4.02  Maintenance of Office or Agency.
              -------------------------------

     So long as any series of the Securities remain Outstanding, the Company
agrees to maintain an office or agency in the Borough of Manhattan, the City and
State of New York, with respect to each such series and at such other location
or locations as may be designated as provided in this Section 4.02, where (i)
Securities of that series may be presented for payment, (ii) Securities of that
series may be presented as herein authorized for registration of transfer and
exchange, and (iii) notices and demands to or upon the Company in respect of the
Securities of that series and this Indenture may be given or served, such
designation to continue with respect to such office or agency until the Company
shall, by written notice signed by any Officer and delivered to the Trustee,
designate some other office or agency for such purposes or any of them.  If at
any time the Company shall fail to maintain any such required office or agency
or shall fail to furnish the Trustee with the address thereof, such
presentations, notices and demands may be made or served at the Corporate Trust
Office of the Trustee, and the Company hereby appoints the Trustee as its agent
to receive all such presentations, notices and demands.

Section 4.03  Paying Agents.
              -------------

     (a)  The Company may appoint one or more paying agents for all or any
series of the Securities, other than the Trustee. If the Company fails to
appoint or maintain another entity as paying agent, the Trustee shall act as
such. The Company or any of its Subsidiaries may act as paying agent.

     (b)  The Company shall require each paying agent other than the Trustee to
agree in writing that the paying agent will hold in trust for the benefit of
Securityholders or the Trustee all money held by the paying agent for the
payment of principal or interest on the Securities, and will promptly notify the
Trustee in writing of any default by the Company in making any such payment.
While any such default continues, the Trustee may require a paying agent to pay
all money held by it to the Trustee.  The Company at any time may require a
paying agent to pay all money held by it to the Trustee.  Upon payment over to
the Trustee, the paying agent (if other than the Company or a Subsidiary) shall
have no further liability for the money.  If the Company or a Subsidiary acts as
paying agent, it shall segregate and hold in a separate trust fund for the
benefit of the Securityholders all money held by it as paying agent.

     (c)  Notwithstanding anything in this Section to the contrary, (i) the
agreement to hold sums in trust as provided in this Section 4.03 is subject to
the provisions of Section 11.05, and (ii) the Company may at any time, for the
purpose of obtaining the satisfaction and discharge or defeasance of this
Indenture or for any other purpose, pay, or direct any paying agent to pay, to
the Trustee all sums held in trust by the Company or such paying agent, such
sums to be held by the Trustee upon the same terms and conditions as those upon
which such sums were held by the Company or such paying agent; and, upon such
payment by any paying agent to the Trustee, such paying agent shall be released
from all further liability with respect to such money.

     The Company shall, and shall cause each of its Subsidiaries to, comply with
all statutes, laws, ordinances, or government rules and regulations to which it
is subject, noncompliance with

                                      17

which would materially adversely affect the business, earnings, properties,

Section 4.06  Statement by Officers as to Default.
              -----------------------------------

     The Company, so long as any Securities are Outstanding, will deliver to the
Trustee, within 120 days after the end of each fiscal year of the Company ending
after the date hereof, an Officers' Certificate signed by its principal
executive officer, principal financial officer or principal accounting officer
stating whether or not to the best knowledge of the signer thereof the Company
is in default in the performance and observance of any of the terms, provisions
and conditions of this Indenture, and if the Company shall be in default,
specifying all such defaults and the nature and status thereof of which they may
have knowledge.

     The Company, so long as any Securities are Outstanding, shall promptly
deliver to the Trustee, forthwith upon any Officer becoming aware of the
occurrence of any Event of Default or an event which, with notice or the lapse
of time or both, would constitute an Event of Default, an Officers' Certificate
specifying such Event of Default or Default and the action which the Company
proposes to make with respect thereto.

Section 4.07  Waiver of Certain Covenants
              ---------------------------

     The Company may omit in any particular instance to comply with any term,
provision or condition set forth in Sections 4.04 and 4.05 with respect to the
Securities of any series if before or after the time for such compliance the
Securityholders of at least a majority in principal amount of all Outstanding
Securities of such series, by act of such Securityholders, either waive such
compliance in such instance or generally waive compliance with such covenant or
condition, but no such waiver shall extend to or affect such covenant or
condition except to the extent so expressly waived, and, until such waiver shall
become effective, the obligations of the Company and the duties of the Trustee
in respect of any such term, provision or condition shall remain in full force
and effect.

provided, the holders of a majority in aggregate principal amount of the
Securities of that series then Outstanding hereunder, by written notice to the
Company and the Trustee, may rescind and annul such declaration and its
consequences if:  (i) the Company has paid or deposited with the Trustee a sum
sufficient to pay all matured installments of interest upon all the Securities
of that series and the principal of (and

                                      21
<PAGE>

premium, if any, on) any and all Securities of that series that shall have
become due otherwise than by acceleration (with interest upon such principal and
premium, if any, and, to the extent that such payment is enforceable under
applicable law, upon overdue installments of interest, at the rate per annum
expressed in the Securities of that series to the date of such payment or
deposit), and (ii) any and all Events of Default under the Indenture with
respect to such series, other than the nonpayment of principal on Securities of
that series that shall not have become due by their terms, shall have been
remedied or waived as provided in Section 6.06.

     No such rescission and annulment shall extend to or shall affect any
subsequent default or impair any right consequent thereon.

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

Section 6.02  Collection of Indebtedness and Suits for Enforcement by Trustee.
              ---------------------------------------------------------------

     (a)  The Company covenants that (1) in case it shall default in the payment
of any installment of interest on any of the Securities of a series, or any
payment required by any sinking or analogous fund established with respect to
that series as and when the same shall have become due and payable, and such
default shall have continued for a period of 90 Business Days, or (2) in case it
shall default in the payment of the principal of (or premium, if any, on) any of
the Securities of a series when the same shall have become due and payable,
whether upon maturity of the Securities of a series or upon redemption or upon
declaration or otherwise, then, upon demand of the Trustee, the Company will pay
to the Trustee, for the benefit of the holders of the Securities of that series,
the whole amount that then shall have been become due and payable on all such
Securities for principal (and premium, if any) or interest, or both, as the case
may be, with interest upon the overdue principal (and premium, if any) and (to
the extent that payment of such interest is enforceable under applicable law)
upon overdue installments of interest at the rate per annum expressed in the
Securities of that series; and, in addition thereto, such further amount as
shall be sufficient to cover the costs and expenses of collection, and the
amount payable to the Trustee under Section 7.06.

     (b)  If the Company shall fail to pay such amounts forthwith 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 proceeding to judgment or final decree, and may enforce any such
judgment or final decree against the Company and collect the moneys adjudged or
decreed to be payable in the manner provided by law out of the property of the
Company, wherever situated.

     (c)  In case of any receivership, insolvency, liquidation, bankruptcy,
reorganization, readjustment, arrangement, composition or judicial proceedings
affected the Company, or its

                                      22
<PAGE>

creditors or property, the Trustee shall have power to intervene in such
proceedings and take any action therein that may be permitted by the court and
shall (except as may be otherwise provided by law) be entitled to file such
proofs of claim and other papers and documents as may be necessary or advisable
in order to have the claims of the Trustee and of the holders of Securities of
such series allowed for the entire amount due and payable by the Company under
the Indenture at the date of institution of such proceedings and for any
additional amount that may become due and payable by the Company after such
date, and to collect and receive any moneys or other property payable or
deliverable on any such claim, and to distribute the same in accordance with
Section 6.03 hereof; and any receiver, assignee or trustee in bankruptcy or
reorganization is hereby authorized by each of the holders of Securities of such
series to make such payments to the Trustee, and, in the event that the Trustee
shall consent to the making of such payments directly to such Securityholders,
to pay to the Trustee any amount due it under Section 7.06.

     (d)  All rights of action and of asserting claims under this Indenture, or
under any of the terms established with respect to Securities of that series,
may be enforced by the Trustee without the possession of any of such Securities,
or the production thereof at any trial or other proceeding relative thereto, and
any such suit or proceeding instituted by the Trustee shall be brought in its
own name as trustee of an express trust, and any recovery of judgment shall,
after provision for payment to the Trustee of any amounts due under Section
7.06, be for the ratable benefit of the holders of the Securities of such
series.

     In case of an Event of Default hereunder, 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 the 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.

     Nothing contained herein shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Securityholder any
plan of reorganization, arrangement, adjustment or composition affecting the
Securities of that 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.

Section 6.03  Application of Moneys Collected.
              -------------------------------

     Any moneys collected by the Trustee pursuant to this Article VI with
respect to a particular series of Securities shall be applied in the following
order, at the date or dates fixed by the Trustee and, in case of the

interest, upon presentation of the Securities of that series, and notation

of such series for principal (and premium, if any) and interest, in respect of
which or for the benefit of which such money has been collected, ratably,

payable on such Securities for principal (and premium, if any) and interest,
respectively; and

     FOURTH:  To the Company.

Section 6.04  Limitation on Suits.
              -------------------

     No holder of any Security of any series shall have any right by virtue or
by availing himself or herself of any provision of this Indenture to institute
any suit, action or proceeding in equity or at law upon or under or with respect
to this Indenture or for the appointment of a receiver or trustee, or for any
other remedy hereunder, unless (i) such holder previously shall have given to
the Trustee written notice of an Event of Default and of the continuance thereof
with respect to the Securities of such series specifying such Event of Default,
as hereinbefore provided; (ii) the holders of not less than 25% in aggregate
principal amount of the Securities of such series then Outstanding shall have
made written request upon the Trustee to institute such action, suit or
proceeding in its own name as trustee hereunder; (iii) such holder or holders
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;
(iv) the Trustee for 60 days after its receipt of such notice, request and offer
of indemnity, shall have failed to institute any such action, suit or
proceeding; and (v) during such 60 day period, the holders of a majority in
principal amount of the Securities of that series do not give the Trustee a
direction inconsistent with the request.

     Notwithstanding anything contained herein to the contrary, any other
provisions of this Indenture, the right of any holder of any Security to receive
payment of the principal of (and premium, if any) and interest on such Security,
as therein provided, on or after the respective due dates expressed in such
Security (or in the case of redemption, on the redemption date), or to institute
suit for the enforcement of any such payment on or after such respective dates
or redemption date, shall not be impaired or affected without the consent of
such holder and by accepting a Security hereunder it is expressly understood,
intended and covenanted by the taker and holder of every Security of such series
with every other such taker and holder and the Trustee, that no one or more
holders of Securities of such series shall have any right in any manner
whatsoever by virtue or by availing himself or herself of any provision of this
Indenture to affect, disturb or prejudice the rights of the holders of any other
of 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 such series.  For the protection and enforcement of
the provisions of this Section 6.04, each and every Securityholder and the
Trustee shall be entitled to such relief as can be given either at law or in
equity.

Section 6.05  Rights and Remedies Cumulative; Delay or Omission not Waiver.
              ------------------------------------------------------------

     (a)  Except as otherwise provided in Section 2.07, all powers and remedies
given by this Article VI to the Trustee or to the Securityholders shall, to the
extent permitted by law, be deemed cumulative and not exclusive of any other
powers and remedies available to the Trustee or the holders of the Securities,
by judicial proceedings or otherwise, to enforce the performance or observance
of the covenants and agreements contained in this Indenture or otherwise
established with respect to such Securities.

     (b)  No delay or omission of the Trustee or of any holder of any of the
Securities to exercise any right or power accruing upon any Event of Default
occurring and continuing as aforesaid shall impair any such right or power, or
shall be construed to be a waiver of any such default or on acquiescence
therein; and, subject to the provisions of Section 6.04, every power and remedy
given by this Article VI or by law to the Trustee or the Securityholders may be
exercised from time to time, and as often as shall be deemed expedient, by the
Trustee or by the Securityholders.

Section 6.06  Control by Securityholders.
              --------------------------

     The holders of a majority in aggregate principal amount of the Securities
of any series at the time Outstanding, determined in accordance with Section
8.04, shall have the right to direct the time, method and place of conducting
any proceeding for any remedy available to the Trustee or exercising any trust
or power conferred on the Trustee with respect to such series; provided,
                                                               --------
however, that such direction shall not be in conflict with any rule of law or
-------
with this Indenture or be unduly prejudicial to the rights of holders of
Securities of any other series at the time Outstanding determined in accordance
with Section 8.04.  Subject to the provisions of Section 7.01, the Trustee shall
have the right to decline to follow any such direction if the Trustee in good
faith shall, by a Responsible Officer or Responsible Officers of the Trustee,
determine that the proceeding so directed would involve the Trustee in personal
liability. The holders of a majority in aggregate principal amount of the
Securities of any series at the time Outstanding affected thereby, determined in
accordance with Section 8.04, may on behalf of the holders of all of the
Securities of such series waive any past default in the performance of any of
the covenants contained herein or established pursuant to Section 2.01 with
respect to such series and its consequences, except a default in the payment of
the principal of, or premium, if any, or interest on, any of the Securities of
that series as and when the same shall become due by the terms of such
Securities otherwise than by acceleration (unless such default has been cured
and a sum sufficient to pay all matured installments of interest and principal
and any premium has been deposited with the Trustee (in accordance with Section
6.01(c)).  Upon any such waiver, the default covered thereby shall be deemed to
be cured for all purposes of this Indenture and the Company, the Trustee and the
holders of the Securities of such series 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.

Section 6.07  Undertaking to Pay Costs.
              ------------------------

     All parties to this Indenture agree, and each holder of any Securities by
such holder's acceptance thereof shall be deemed to have agreed, that any court
may in its discretion require, in

                                      25
<PAGE>

any suit for the enforcement of any right or remedy under this Indenture, or in
any suit against the Trustee for any action taken or omitted by it as Trustee,
the filing by any party litigant in such suit of an undertaking to pay the costs
of such suit, and that such court may in its discretion assess reasonable costs,
including reasonable attorneys' fees and expenses, against any party litigant in
such suit, having due regard to the merits and good faith of the claims or
defenses made by such party litigant; but the provisions of this Section 6.07
shall not apply to any suit instituted by the Trustee, to any suit instituted by
any Securityholder, or group of Securityholders, holding more than 10% in
aggregate principal amount of the Outstanding Securities of any series, or to
any suit instituted by any Securityholder for the enforcement of the payment of
the principal of (or premium, if any) or interest on any Security of such
series, on or after the respective due dates expressed in such Security or
established pursuant to this Indenture.

Section 6.08  Waiver Of Usury, Stay Or Extension Laws
              ---------------------------------------

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

has occurred (that has not been cured or waived), the Trustee shall exercise
with respect to Securities of that series 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.

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

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

               (i)    the duties and obligations of the Trustee shall with
          respect to the Securities of such series be determined solely by the
          express provisions of this Indenture, and the Trustee shall not be
          liable with respect to the Securities of such series except for the
          performance of such duties and obligations as are specifically

                                      26
<PAGE>

          set forth in this Indenture, and no implied covenants or obligations

          or opinions furnished to the Trustee and conforming to the
          requirements of this Indenture; but in the case of any such
          certificates or opinions that 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 (but need not confirm or
          investigate the accuracy of mathematical computations or other facts
          stated therein);

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;

or omitted to be taken by it in good faith in accordance with the direction of
the holders of not less than a majority in principal amount of the Securities of

conducting any proceeding for any remedy available to the Trustee, or exercising
any trust or power conferred upon the Trustee under this Indenture with respect

the Trustee to expend or risk its own funds or otherwise incur personal
financial liability in the performance of any of its duties or in the exercise
of any of its rights or powers, if there is reasonable ground for believing that
the repayment of such funds or liability is not reasonably assured to it under
the terms of this Indenture or adequate indemnity against such risk is not
reasonably assured to it.

              -------------------------

     Except as otherwise provided in Section 7.01:

of not less than a majority in principal amount of the Outstanding Securities of
the particular series affected thereby (determined as provided in Section 8.04);
provided, however, that if the payment within a reasonable time to the Trustee
--------  -------
of the costs, expenses or liabilities likely to be incurred by it in the making
of such investigation is, in the opinion of the Trustee, not reasonably assured
to the Trustee by the security afforded to it by the terms of this Indenture,
the Trustee may require reasonable indemnity against such costs, expenses or
liabilities as a condition to so proceeding. The reasonable expense of every
such examination shall be paid by the Company or, if paid by the Trustee, shall
be repaid by the Company upon demand;

     (g)  the Trustee shall not be deemed to have notice of any Event of Default

<PAGE>

matter (unless other evidence in respect thereof be herein specifically
prescribed) may, in the absence of negligence or bad faith on the part of the

provisions of this Indenture upon the faith thereof.

common control with the Company, serve as Trustee.  In case at any time the
Trustee shall cease to be eligible in accordance with the provisions of this
Section 7.09, the Trustee shall resign immediately in the manner and with the

Section 7.10  Resignation and Removal; Appointment of Successor.
              -------------------------------------------------

     (a)  The Trustee or any successor hereafter appointed may at any time
resign with respect to the Securities of one or more series by giving written
notice thereof to the Company and by transmitting notice of resignation by mail,
first class postage prepaid, to the Securityholders of such series, as their
names and addresses appear upon the Security Register. Upon receiving such
notice of resignation, the Company shall promptly appoint a successor trustee

been so appointed and have accepted appointment within 60 days after the
retiring Trustee resigns, the retiring Trustee, at the expense of the Company,
or the Company may petition any court of competent jurisdiction for the
appointment of a successor trustee with respect to Securities of such series, or

as provided herein, any Securityholder who has been a bona fide holder of a
Security or Securities for at least six months may, on behalf of that holder and
all others similarly situated, petition any court of competent jurisdiction for
the removal of the Trustee and the appointment of a successor trustee.  Such
court may thereupon after such notice, if any, as it may deem proper and
prescribe, remove the Trustee and appoint a successor trustee:

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

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

          (3)  the Trustee shall become incapable of acting, or shall be
adjudged a bankrupt or insolvent, or commence a voluntary bankruptcy proceeding,
or a receiver of the Trustee or of its property shall be appointed or consented
to, 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.

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

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

     (e)  Any successor trustee appointed pursuant to this Section 7.10 may be

Section 7.11  Acceptance of Appointment By Successor.
              --------------------------------------

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

                                      31
<PAGE>

Trustee and shall duly assign, transfer and deliver to such successor trustee
all property and money held by such retiring Trustee hereunder.

     (b)  In case of the appointment hereunder of a successor trustee with
respect to the Securities of one or more (but not all) series, the Company, the
retiring Trustee and each successor trustee with respect to the Securities of
one or more series shall execute and deliver an indenture supplemental hereto
wherein each successor trustee shall accept such appointment and which (1) shall
contain such provisions as shall be necessary or desirable to transfer and
confirm to, and to vest in, each successor trustee all the rights, powers,
trusts and duties of the retiring Trustee with respect to the Securities of that
or those series to which the appointment of such successor trustee relates, (2)
shall contain such provisions as shall be deemed necessary or desirable to
confirm that all the rights, powers, trusts and duties of the retiring Trustee
with respect to the Securities of that or those series as to which the retiring
Trustee is not retiring shall continue to be vested in the retiring Trustee, and
(3) shall add to or change any of the provisions of this Indenture as shall be
necessary to provide for or facilitate the administration of the trusts
hereunder by more than one Trustee, it being understood that nothing herein or
in such supplemental indenture shall constitute such Trustees co-trustees of the
same trust, that each such Trustee shall be trustee of a trust or trusts
hereunder separate and apart from any trust or trusts hereunder administered by
any other such Trustee and that no Trustee shall be responsible for any act or
failure to act on the part of any other Trustee hereunder; and upon the
execution and delivery of such supplemental indenture the resignation or removal
of the retiring Trustee shall become effective to the extent provided therein,
such retiring Trustee shall with respect to the Securities of that or those
series to which the appointment of such successor trustee relates have no
further responsibility for the exercise of rights and powers or for the
performance of the duties and obligations vested in the Trustee under this
Indenture, and each such successor trustee, without any further act, deed or
conveyance, shall become vested with all the rights, powers, trusts and duties
of the retiring Trustee with respect to the Securities of that or those series
to which the appointment of such successor trustee relates; but, on request of
the Company or any successor trustee, such retiring Trustee shall duly assign,
transfer and deliver to such successor trustee, to the extent contemplated by
such supplemental indenture, the property and money held by such retiring
Trustee hereunder with respect to the Securities of that or those series to
which the appointment of such successor trustee relates.

     (c)  Upon request of any such successor trustee, the Company may execute
any and all instruments for more fully and certainly vesting in and confirming
to such successor trustee all such rights, powers and trusts referred to in
paragraph (a) or (b) of this Section 7.11, as the case may be.

     (d)  No successor trustee shall accept its appointment unless at the time
of such acceptance such successor trustee shall be qualified and eligible under
this Article VII.

     (e)  Upon acceptance of appointment by a successor trustee as provided in
this Section 7.11, the successor trustee shall cause a notice of its succession
to be transmitted to Securityholders.

Section 7.12  Merger, Conversion, Consolidation or Succession to Business.
              -----------------------------------------------------------

     Any corporation into which the Trustee may be merged or converted or with
which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any
corporation succeeding to all or substantially all of the corporate trust
business of the Trustee, shall be the successor of the Trustee hereunder,
provided that such corporation shall be qualified under the provisions of
Section 7.08 and eligible under the provisions of Section 7.09, without the
execution or filing of any paper or any further act on the part of any of the
parties hereto, anything herein to the contrary notwithstanding.  In case any
Securities shall have been authenticated, but not delivered, by the Trustee then
in office, any successor by merger, conversion or consolidation to such
authenticating Trustee may adopt such authentication and deliver the Securities
so authenticated with the same effect as if such successor Trustee had itself
authenticated such Securities.

Section 7.13  Preferential Collection of Claims Against the Company.
              -----------------------------------------------------

     The Trustee shall comply with Section 311(a) of the Trust Indenture Act,

                                 ARTICLE VIII.

                        CONCERNING THE SECURITYHOLDERS

Section 8.01  Evidence of Action by Securityholders.
              -------------------------------------

     Whenever in this Indenture it is provided that the holders of a majority or
specified percentage in aggregate principal amount of the Securities of a
particular series may take any action (including the making of any demand or
request, the giving of any notice, consent or waiver or the taking of any other
action), the fact that at the time of taking any such action the holders of such
majority or specified percentage of that series have joined therein may be
evidenced by any instrument or any number of instruments of similar tenor
executed by such holders of Securities of that series in Person or by agent or
proxy appointed in writing.

     If the Company shall solicit from the Securityholders of any series any
request, demand, authorization, direction, notice, consent, waiver or other
action, the Company may, at its option, as evidenced by an Officers'
Certificate, fix in advance a record date for such series for the determination
of Securityholders entitled to give such request, demand, authorization,
direction, notice, consent, waiver or other action, but the Company shall have
no obligation to do so.  If such a record date is fixed, such request, demand,
authorization, direction, notice, consent, waiver or other action may be given
before or after the record date, but only the Securityholders of record at the
close of business on the record date shall be deemed to be Securityholders for
the purposes of determining whether Securityholders of the requisite proportion
of Outstanding Securities of that series have authorized or agreed or consented
to such request, demand, authorization, direction, notice, consent, waiver or
other action, and for that purpose the Outstanding Securities of that series
shall be computed as of the record date; provided, however,
                                         --------  -------

                                      33
<PAGE>

that no such authorization, agreement or consent by such Securityholders on the
record date shall be deemed effective unless it shall become effective pursuant
to the provisions of this Indenture not later than six months after the record
date.

Section 8.02  Proof of Execution by Securityholders.
              -------------------------------------

     Subject to the provisions of Section 7.01, proof of the execution of any
instrument by a Securityholder (such proof will not require notarization) or his
agent or proxy and proof of the holding by any Person of any of the Securities
shall be sufficient if made in the following manner:

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

     (b)  The ownership of Securities shall be proved by the Security Register
of such Securities or by a certificate of the Security Registrar thereof.

     (c)  The Trustee may require such additional proof of any matter referred
to in this Section as it shall deem necessary.

Section 8.03  Who May be Deemed Owners.
              ------------------------

     Prior to the due presentment for registration of transfer of any Security,
the Company, the Trustee, any paying agent and any Security Registrar may deem
and treat the Person in whose name such Security shall be registered upon the
books of the Company as the absolute owner of such Security (whether or not such
Security shall be overdue and notwithstanding any notice of ownership or writing
thereon made by anyone other than the Security Registrar) for the purpose of
receiving payment of or on account of the principal of, premium, if any, and
(subject to Section 2.03) interest on such Security and for all other purposes;
and neither the Company nor the Trustee nor any paying agent nor any Security
Registrar shall be affected by any notice to the contrary.

Section 8.04  Certain Securities Owned by Company Disregarded.
              -----------------------------------------------

     In determining whether the holders of the requisite aggregate principal
amount of Securities of a particular series have concurred in any direction,
consent of waiver under this Indenture, the Securities of that series that are
owned by the Company or any other obligor on the Securities of that series or by
an Affiliate 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 of such series that a Responsible Officer of the
Trustee knows are so owned shall be so disregarded.  The Securities so owned
that have been pledged in good faith may be regarded as Outstanding for the
purposes of this Section, if the pledgee shall establish to the satisfaction of
the Trustee the pledgee's right so to act with respect to such Securities and
that the pledgee is not an Affiliate.  In case of a dispute as to such right,
any decision by the Trustee taken upon the advice of counsel shall be full
protection to the Trustee.

Section 8.05  Actions Binding on Future Securityholders.
              -----------------------------------------

     At any time prior to (but not after) the evidencing to the Trustee, as
provided in Section 8.01, of the taking of any action by the holders of the
majority or percentage in aggregate principal amount of the Securities of a
particular series specified in this Indenture in connection with such action,
any holder of a Security of that series that is shown by the evidence to be
included in the Securities the holders of which have consented to such action
may, by filing written notice with the Trustee, and upon proof of holding as
provided in Section 8.02, revoke such action so far as concerns such Security.
Except as aforesaid any such action taken by the holder of any Security shall be
conclusive and binding upon such holder and upon all future holders and owners
of such Security, and of any Security issued in exchange therefor, on
registration of transfer thereof or in place thereof, irrespective of whether or
not any notation in regard thereto is made upon such Security.  Any action taken
by the holders of the majority or percentage in aggregate principal amount of
the Securities of a particular series specified in this Indenture in connection
with such action shall be conclusively binding upon the Company, the Trustee and
the holders of all the Securities of that series.

                            SUPPLEMENTAL INDENTURES

Section 9.01  Supplemental Indentures Without the Consent of Securityholders.
              ---------------------------------------------------------------

     In addition to any supplemental indenture otherwise authorized by this
Indenture, the Company and the Trustee may from time to time and at any time
enter into an indenture or indentures supplemental hereto (which shall conform
to the provisions of the Trust Indenture Act as then in effect), without the
consent of the Securityholders, for one or more of the following purposes:

benefit of less than all series of Securities, stating that such covenants are
expressly being included solely for the benefit of such series) or to surrender
any right or power herein conferred upon the Company;

     (e)  to add to, delete from, or revise the conditions, limitations, and
restrictions on the authorized amount, terms, or purposes of issue,
authentication, and delivery of Securities, as herein set forth;

                                      35
<PAGE>

     (f)  to make any change that does not adversely affect the rights of any
Securityholder in any material respect; or

     (g)  to provide for the issuance of and establish the form and terms and
conditions of the Securities of any series as provided in Section 2.01, to
establish the form of any certifications required to be furnished pursuant to
the terms of this Indenture or any series of Securities, or to add to the rights
of the holders of any series of Securities.

     Upon the request of the Company, accompanied by Board Resolutions
authorizing the execution of any such supplemental indenture, and upon receipt
by the Trustee of the documents described in Section 9.05 hereof, the Trustee
shall join with the Company in the execution of any such supplemental indenture,
and to make any further appropriate agreements and stipulations that may be
therein contained, but the Trustee shall not be obligated to enter into any such
supplemental indenture that affects the Trustee's own rights, duties or
immunities under this Indenture or otherwise.

     Any supplemental indenture authorized by the provisions of this Section
9.01 may be executed by the Company and the Trustee without the consent of the
holders of any of the Securities at the time Outstanding, notwithstanding any of
the provisions of Section 9.02.

Section 9.02  Supplemental Indentures with Consent of Securityholders.
              -------------------------------------------------------

     With the consent (evidenced as provided in Section 8.01) of the holders of
not less than a majority in aggregate principal amount of the Securities of each
series affected by such supplemental indenture or indentures at the time
Outstanding, the Company, when authorized by  Board Resolutions, and the Trustee
may from time to time and at any time enter into an indenture or indentures
supplemental hereto (which shall conform to the provisions of the Trust
Indenture Act as then in effect) for the purpose of adding any provisions to or
changing in any manner or eliminating any of the provisions of this Indenture or
of any supplemental indenture or of modifying in any manner not covered by
Section 9.01 the rights of the holders of the Securities of such series under
this Indenture; provided, however, that no such supplemental indenture shall,
                --------  -------
without the consent of the holders of each Security then Outstanding and
affected thereby, (i) extend the fixed maturity of any Securities of any series,
reduce the principal amount thereof, reduce the rate or extend the time of
payment of interest thereon, or reduce any premium payable upon the redemption
thereof or (ii) reduce the aforesaid percentage of Securities, the holders of
which are required to consent to any such supplemental indenture.

     It shall not be necessary for the consent of the Securityholders of any
series affected thereby under this Section 9.02 to approve the particular form
of any proposed supplemental indenture, but it shall be sufficient if such
consent shall approve the substance thereof.

Section 9.03  Effect of Supplemental Indentures.
              ---------------------------------

     Upon the execution of any supplemental indenture pursuant to the provisions
of this Article IX or Section 10.01, this Indenture shall, with respect to such
series, be and be deemed to be modified and amended in accordance therewith and
the respective rights, limitations of rights, obligations, duties and immunities
under this Indenture of the Trustee, the Company and the holders of Securities
of the series affected thereby shall thereafter be determined, exercised and

                                      36

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 9.04  Securities Affected by Supplemental Indentures.
              ----------------------------------------------

     Securities of any series affected by a supplemental indenture and
authenticated and delivered after the execution of such supplemental indenture
pursuant to the provisions of this Article or of Section 10.01, may bear a
notation in form approved by the Company, provided such form meets the
requirements of any exchange upon which such series may be listed, as to any
matter provided for in such supplemental indenture.  If the Securities of the
Company shall so determine, new Securities of that series so modified as to
conform, in the opinion of the Board of Directors of the Company, to any
modification of this Indenture contained in any such supplemental indenture may
be prepared by the Company, authenticated by the Trustee and delivered in
exchange for the Securities of that series then Outstanding.

Section 9.05  Execution of Supplemental Indentures.
              ------------------------------------

     Upon the request of the Company, accompanied by its Board Resolutions
authorizing the execution of any such supplemental indenture, and, if
applicable, upon the filing with the Trustee of evidence of the consent of
Securityholders required to consent thereto as aforesaid, the Trustee shall join
with the Company in the execution of such supplemental indenture unless such
supplemental indenture affects the Trustee's own rights, duties or immunities
under this Indenture or otherwise, in which case the Trustee may in its
discretion but shall not be obligated to enter into such supplemental indenture.
The Trustee, subject to the provisions of Section 7.01, may receive an Opinion
of Counsel as conclusive evidence that any supplemental indenture executed
pursuant to this Article IX is authorized or permitted by, and conforms to, the
terms of this Article IX and that it is proper for the Trustee under the
provisions of this Article IX to join in the execution thereof; provided,
                                                                --------
however, that such Opinion of Counsel need not be provided in connection with
-------
the execution of a supplemental indenture that establishes the terms of a series
of Securities pursuant to Section 2.01 hereof.

     Promptly after the execution by the Company and the Trustee of any
supplemental indenture pursuant to the provisions of this Section 9.05, the
Trustee shall transmit by mail, first class postage prepaid, a notice, setting
forth in general terms the substance of such supplemental indenture, to the
Securityholders of all series affected thereby as their names and addresses
appear upon the  Security Register.  Any failure of the Trustee to mail such
notice, or any defect therein, shall not, however, in any way impair or affect
the validity of any such supplemental indenture.

Opinion of Counsel stating that the proposed transaction and such supplemental
indenture comply with this Indenture.

defeasance"), such discharge to be effective on the date the conditions set
forth in clauses (i) through (vi) of this Section 11.02(b) are satisfied, and
such Securities shall thereafter be deemed to be not "Outstanding" for the
purposes of any direction, waiver, consent or declaration of Securityholders
(and the consequences of any thereof) in connection with such covenants, but
shall continue to be "Outstanding" for all other purposes under this Indenture.
For this purpose, such covenant defeasance means that, with respect to the
Outstanding Securities of a series, the Company may omit to comply with and
shall have no liability in respect of any term, condition or limitation set
forth in any such covenant, whether directly or indirectly, by reason of any
reference elsewhere herein to any such covenant or by reason of reference in any
such covenant to any other provision herein or in any other document and such
omission to comply shall not constitute an Event of Default under Section
6.01(a)(3) or otherwise, but except as specified in this Section 11.02(b), the
remainder of the Company's obligations under the Securities of such series, this
Indenture, and any indentures supplemental to this Indenture with respect to
such series shall be unaffected thereby.

          The following shall be the conditions to the application of Section
11.02(b) to the Outstanding Securities of the applicable series:

               (i)    the Company irrevocably deposits in trust with the Trustee
          or, at the option of the Trustee, with a trustee satisfactory to the
          Trustee and the Company under the terms of an irrevocable trust
          agreement in form and substance satisfactory to the Trustee, money or
          Governmental Obligations sufficient to pay principal and interest on
          the Outstanding Securities of such series to maturity or redemption,
          as the case may be, and to pay all other sums payable by it hereunder,
          provided that (A) the trustee of the irrevocable trust shall have been
          --------
          irrevocably instructed to pay such money or the proceeds of such
          Governmental Obligations to the Trustee and (B) the Trustee shall have
          been irrevocably instructed to apply such money or the proceeds of
          such Governmental Obligations to the payment of said principal and
          interest with respect to the Securities of such series;

               (ii)   the Company delivers to the Trustee an Officers'
          Certificate stating that all conditions precedent specified herein
          relating to defeasance or covenant defeasance, as the case may be,
          have been complied with, and an Opinion of Counsel to the same effect;

               (iii)  no Event of Default under clauses (1), (2), (4) or (5) of
          Section 6.01(a) shall have occurred and be continuing, and no event
          which with notice or lapse of time or both would become such an Event
          of Default shall have occurred and be continuing, on the date of such
          deposit;

               (iv)   the Company shall have delivered to the Trustee an Opinion
          of Counsel or a ruling received from the Internal Revenue Service to
          the effect that the holders of the Securities of such series will not
          recognize income, gain or loss

                                      40
<PAGE>

          for Federal income tax purposes as a result of the Company's exercise
          of either option under this Section 11.02 and will be subject to
          Federal income tax in the same amount and in the same manner and at
          the same times as would have been the case if such election had not
          been exercised;

               (v)   such covenant defeasance shall not cause the Trustee to
          have a conflicting interest for purposes of the Trust Indenture Act
          with respect to any Securities; and

               (vi)  notwithstanding any other provisions of this Section 11.02,
          such covenant defeasance shall be effected in compliance with any
          additional or substitute terms, conditions or limitations which may be
          imposed on the Company pursuant to Section 2.01.

     After such irrevocable deposit made pursuant to this Section 11.02(b) and
satisfaction of the other conditions set forth herein, the Trustee upon request
shall acknowledge in writing the discharge of the Company's obligations pursuant
to this Section 11.02(b).

Section 11.03  Deposited Moneys to be Held in Trust.
               ------------------------------------

     All moneys or Governmental Obligations deposited with the Trustee pursuant
to Sections 11.01 or 11.02 shall be held in trust and shall be available for
payment as due, either directly or through any paying agent (including the
Company acting as its own paying agent), to the holders of the particular series
of Securities for the payment or redemption of which such moneys or Governmental
Obligations have been deposited with the Trustee.

Section 11.04  Payment of Moneys Held by Paying Agents.
               ---------------------------------------

     In connection with the provisions of Section 11.01 or 11.02, all moneys or
Governmental Obligations then held by any paying agent under the provisions of
this Indenture shall, upon demand of the Company, be paid to the Trustee and
thereupon such paying agent shall be released from all further liability with
respect to such moneys or Governmental Obligations.

Section 11.05  Repayment to Company.
               --------------------

     Any moneys or Governmental Obligations deposited with any paying agent or
the Trustee, or then held by the Company, in trust for payment of principal of
or premium or interest on the Securities of a particular series that are not
applied but remain unclaimed by the holders of such Securities for at least two
years after the date upon which the principal of (and premium, if any) or
interest on such Securities shall have respectively become due and payable,
shall be repaid to the Company on the last Business Day of each fiscal year of
the Company, or (if then held by the Company) shall be discharged from such
trust; and thereafter, the paying agent and the Trustee shall be released from
all further liability with respect to such moneys or Governmental Obligations,
and the holder of any of the Securities entitled to receive such payment shall
thereafter, as an unsecured general creditor, look only to the Company for the
payment thereof.  Anything in this Article XI to the contrary notwithstanding,
subject to Section 7.06, the Trustee shall deliver or pay to the Company from
time to time upon request by the Company any money or Governmental Obligations
(or other property and any proceeds

                                      41
<PAGE>

therefrom) held by it as provided in Sections 11.01 or 11.02 which, in the
opinion of a nationally recognized firm of independent public accountants
expressed in a written certification thereof delivered to the Trustee, are in
excess of the amount thereof which would then be required to be deposited to
effect a defeasance or covenant defeasance, as the case may be, in accordance
with this Article XI. On the last business day of each fiscal year of the
Company, or (if then held by the Company) shall be discharged from such trust,
and thereafter.

Section 11.06  Reinstatement.
               -------------

     If the Trustee or paying agent is unable to apply any money or Governmental
Obligations in accordance with Section 11.01 or 11.02 by reason of any legal
proceeding or by reason of any order or judgment of any court or governmental
authority enjoining, restraining or otherwise prohibiting such application, the
Company's obligations under this Indenture, any indentures supplemental to the
Indenture with respect to the applicable series of Securities and the Securities
of such series shall be revived and reinstated as though no deposit had occurred
pursuant to Section 11.01 or 11.02, as the case may be, until such time as the
Trustee or paying agent is permitted to apply all such money or Governmental
Obligations in accordance with Section 11.01 or 11.02, as the case may be;
provided, however, that if the Company has made any payment of interest on or
--------  -------
principal of any Securities of such series following the reinstatement of its
obligations as aforesaid, the Company shall be subrogated to the rights of the
holders of such Securities of such series to receive such payment from the money
or Governmental Obligations held by the Trustee or paying agent.

or successor corporation, either directly or through the Company or any such
predecessor or successor corporation, whether by virtue of any constitution,
statute or rule of law, or by the enforcement of any assessment or penalty or

issued hereunder are solely corporate obligations, and that no such personal

the Securities or implied therefrom; and that any and all such personal
liability of every name and nature, either at common law or in equity or by

the creation of the indebtedness hereby authorized, or under or by reason of the
obligations, covenants or agreements contained in this Indenture or in any of
the Securities or implied therefrom, are hereby expressly waived

                                      42

indentures supplemental to this Indenture, in any case where the date of
maturity of interest or principal of any Security or the date of redemption of
any Security shall not be a Business Day, then payment of interest or principal

or unenforceable in any respect, such invalidity, illegality or unenforceability
shall not affect any other provisions of this Indenture or of such Securities,
but this Indenture and such Securities shall be construed as if such invalid or
illegal or unenforceable provision had never been contained herein or therein.
