SECTION 2.02 Form of Securities and Trustee's Certificate.

     The Securities of any series and the Trustee's certificate of
authentication to be borne by such Securities shall be substantially of the
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(11). The Securities of a particular series
shall bear interest payable on the dates and at the rate specified 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. 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.

     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 by virtue of having
been such holder; and such Defaulted Interest shall be paid by the Company, at
its election, as provided in clause (1) or clause (2) below:

          (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

                                      -7-
<PAGE>

     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 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.

          (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, if, after
     notice given by the Company to the Trustee of the proposed payment pursuant
     to this clause, such manner of payment shall be deemed practicable by the
     Trustee.

     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.

SECTION 2.04 Execution and Authentications.

     The Securities shall be signed on behalf of the Company by its President,
or one of its Vice Presidents, or its Treasurer, or one of its Assistant
Treasurers, or its Secretary, or one of its Assistant Secretaries, under its
corporate seal attested by its Secretary or one of its Assistant Secretaries.
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 a President or
Vice President thereof, or of any Person who shall have been a Secretary or
Assistant Secretary thereof, notwithstanding the fact that at the time the
Securities shall be authenticated and delivered or


                                      -8-
<PAGE>


disposed of such Person shall have ceased to be the President or a Vice
President, or the Secretary or an Assistant Secretary, of the Company. The seal
of the Company may be in the form of a facsimile of such seal and may be
impressed, affixed, imprinted or otherwise reproduced on the Securities. 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 its President or any Vice President and its Secretary or
any Assistant Secretary, and the Trustee in accordance with such written order
shall authenticate and deliver such Securities.

     In authenticating such Securities and accepting the additional
responsibilities under this Indenture in relation to such Securities, the
Trustee shall be entitled to receive, and (subject to Section 7.01) shall be
fully protected in relying upon, an Opinion of Counsel stating that the form and
terms thereof have been established in conformity with the provisions of this
Indenture.

     The Trustee shall not be required to authenticate such Securities if the
issue of such Securities pursuant to this Indenture will affect the Trustee's
own rights, duties or immunities under the Securities and this Indenture or
otherwise in a manner that is not reasonably acceptable to the Trustee.

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. 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 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").


                                      -9-
<PAGE>


     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.

     All Securities presented or surrendered for exchange or registration of
transfer, as provided in this Section, 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 as aforesaid)
shall authenticate and deliver, a new Security of the same series, bearing a
number not contemporaneously outstanding, 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 of the Company. 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 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 canceled 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 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


                                      -11-
<PAGE>


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 (and, with respect to the provisions of Article
Fourteen, the holders of Senior Indebtedness) 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, with respect to the provisions of Article Fourteen, the
holders of Senior Indebtedness).

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 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 and deliver, a Global Security that (i) shall represent, and
shall be denominated in an amount equal to the aggregate principal amount


                                      -12-
<PAGE>


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 by the
Trustee to the Depositary or 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."

     (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 for such Securities in
definitive registered form without coupons, in authorized denominations, the
Global Security shall be canceled by the Trustee. Such Securities 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.

                                  ARTICLE III

              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.


                                      -13-
<PAGE>


SECTION 3.02 Notice of Redemption.

     (a) In case the Company shall desire to exercise such right to redeem all
or, as the case may be, a portion of the Securities of any series in accordance
with the right reserved so to do, 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, by lot or in such
other manner as it shall deem appropriate and fair in its discretion 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 a denomination larger than $1,000, the Securities to be
redeemed and shall thereafter promptly notify the Company in writing of the
numbers of the Securities 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 its President or any Vice President, 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, 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


                                      -14-
<PAGE>


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.

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 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.

     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


                                      -15-
<PAGE>


terms of such Securities, in each case in satisfaction of all or any part of any
sinking fund payment with respect to the Securities of such series required to
be made pursuant to the terms of such Securities as provided for by the terms of
such series, provided that such Securities have not been previously so credited.
Such Securities shall be received and credited for such purpose by the Trustee
at the redemption price specified in such Securities for redemption through
operation of the sinking fund and the amount of such sinking fund payment shall
be reduced accordingly.

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

                                    COVENANTS

SECTION 4.01 Payment of Principal, Premium and Interest.

     The Company will duly and punctually pay or cause to be paid the principal
of (and premium, if any) and interest on the Securities of that series at the
time and place and in the manner provided herein and established with respect to
such Securities.

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 above 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 its President or a Vice President 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) If the Company shall appoint one or more paying agents for all or any
series of the Securities, other than the Trustee, the Company will cause each
such paying agent to execute and deliver to the Trustee an instrument in which
such agent shall agree with the Trustee, subject to the provisions of this
Section:

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

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

          (3) that it will, at any time during the continuance of any failure
     referred to in the preceding paragraph (a)(2) above, upon the written
     request of the Trustee, forthwith pay to the Trustee all sums so held in
     trust by such paying agent; and

          (4) that it will perform all other duties of paying agent as set forth
     in this Indenture.

     (b) If the Company shall act as its own paying agent with respect to any
series of the Securities, it will on or before each due date of the principal of
(and premium, if any) or interest on Securities of that series, set aside,
segregate and hold in trust for the benefit of the Persons entitled thereto a
sum sufficient to pay such principal (and premium, if any) or interest so
becoming due on Securities of that series until such sums shall be paid to such
Persons or otherwise disposed of as herein provided and will promptly notify the
Trustee of such action, or any failure (by it or any other obligor on such
Securities) to take such action. Whenever the Company shall have one or more
paying agents for any series of Securities, it will, prior to each due date of
the principal of (and premium, if any) or interest on any Securities of that
series, deposit with the paying agent a sum sufficient to pay the principal (and
premium, if any) or interest so becoming due, such sum to be held in trust for
the benefit of the Persons entitled to such principal, premium or interest, and
(unless such paying agent is the Trustee) the Company will promptly notify the
Trustee of this action or failure so to act.

     (c) Notwithstanding anything in this Section to the contrary, (i) the
agreement to hold sums in trust as provided in this Section 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 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.

Trustee, will appoint, in the manner provided in Section 7.10, a Trustee, so

SECTION 4.05 Compliance with Consolidation Provisions.

     The Company will not, while any of the Securities remain Outstanding,
consolidate with or merge into any other Person, in either case where the
Company is not the survivor of such transaction, or sell or convey all or
substantially all of its property to any other company unless the provisions of
Article Ten hereof are complied with.

         REMEDIES OF THE TRUSTEE AND SECURITYHOLDERS ON EVENT OF DEFAULT

SECTION 6.01 Events of Default.

     (a) Whenever used herein with respect to Securities of a particular series,
"Event of Default" means any one or more of the following events that has
occurred and is continuing:

          (1) the Company defaults in the payment of any installment of interest
     upon any of the Securities of that series, as and when the same shall
     become due and payable, and continuance of such default for a period of 90
     days; provided, however, that a valid extension of an interest payment
     period by the Company in accordance with the terms of any indenture
     supplemental hereto, shall not constitute a default in the payment of
     interest for this purpose;

          (2) the Company defaults in the payment of the principal of (or
     premium, if any, on) any of the Securities of that series as and when the
     same shall become due and payable whether at maturity, upon redemption, by
     declaration or otherwise, or in any payment required by any sinking or
     analogous fund established with respect to that series; provided, however,
     that a valid extension of the maturity of such Securities in accordance
     with the terms of any indenture supplemental hereto shall not constitute a
     default in the payment of principal or premium, if any;

          (3) the Company fails to observe or perform any other of its covenants
     or agreements with respect to that series contained in this Indenture or
     otherwise established with respect to that series of Securities pursuant to
     Section 2.01 hereof (other than a covenant or agreement that has been
     expressly included in this Indenture solely for the benefit of one or more
     series of Securities other than such series) for a period of 90 days after
     the date on which written notice of such failure, requiring the same to be
     remedied and stating that such notice is a "Notice of Default" hereunder,
     shall have been given to the Company by the Trustee, by registered or
     certified mail, or to the Company and the Trustee by the holders of at
     least 25% in principal amount of the Securities of that series at the time
     Outstanding;

          (4) the Company pursuant to or within the meaning of any Bankruptcy
     Law (i) commences a voluntary case, (ii) consents to the entry of an order
     for relief against it in an involuntary case, (iii) consents to the
     appointment of a Custodian of it or for all or substantially all of its
     property or (iv) makes a general assignment for the benefit of its
     creditors; or

          (5) a court of competent jurisdiction enters an order under any
     Bankruptcy Law that (i) is for relief against the Company in an involuntary
     case, (ii) appoints a Custodian of the Company for all or substantially all
     of its property, or (iii) orders the liquidation of the Company, and the
     order or decree remains unstayed and in effect for 90 days.

     (b) In each and every such case, unless the principal of all the Securities
of that series shall have already become due and payable, either the Trustee or
the holders of not less than 25% in aggregate principal amount of the Securities
of that series then Outstanding hereunder, by notice in writing to the Company
(and to the Trustee if given by such Securityholders), may declare the principal
of all the Securities of that series to be due and payable immediately, and


                                      -20-
<PAGE>



upon any such declaration the same shall become and shall be immediately due and
payable, notwithstanding anything contained in this Indenture or in the
Securities of that series or established with respect to that series pursuant to
Section 2.01 to the contrary.

     (c) At any time after the principal of the Securities of that series shall
have been so declared due and payable, and before any judgment or decree for the
payment of the moneys due shall have been obtained or entered as hereinafter
provided, the 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 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 the amount payable to
the Trustee under Section 7.06, 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, subject to any determination in such
proceedings, 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,


                                      -21-
<PAGE>


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

     (c) In case of any receivership, insolvency, liquidation, bankruptcy,
reorganization, readjustment, arrangement, composition or judicial proceedings
affected the Company, or its 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 after the
deduction of the amount payable to the Trustee under Section 7.06; 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,


                                      -22-

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 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 distribution of such

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

SECTION 6.04 Limitation on Suits.

     No holder of any Security of any series shall have any right by virtue or
by availing of any provision of this Indenture to institute any 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;
and (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


                                      -23-
<PAGE>


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 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, 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 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 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
8.01, 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 8.01. 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 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 8.01, 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


                                      -24-
<PAGE>


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 any suit for the enforcement of any right or
remedy under this Indenture, or in any suit against the Trustee for any action
taken or omitted by it as Trustee, the filing by any party litigant in such suit
of an undertaking to pay the costs of such suit, and that such court may in its
discretion assess reasonable costs, including reasonable attorneys' fees,
against any party litigant in such suit, having due regard to the merits and
good faith of the claims or defenses made by such party litigant but the
provisions of this Section 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 7.01 Certain Duties and Responsibilities of Trustee.

     (a) The Trustee, prior to the occurrence of an Event of Default with
respect to the Securities of a series and after the curing of all Events of
Default with respect to the Securities of that series that may have occurred,
shall undertake to perform with respect to the Securities of such series such
duties and only such duties as are specifically set forth in this Indenture, and
no implied covenants shall be read into this Indenture against the Trustee. In
case an Event of Default with respect to the Securities of a series 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:


                                      -25-
<PAGE>


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

               (ii) in the absence of bad faith on the part of the Trustee, the
          Trustee may with respect to the Securities of such series conclusively
          rely, as to the truth of the statements and the correctness of the
          opinions expressed therein, upon any certificates or opinions
          furnished to the Trustee and conforming to the requirements of this
          Indenture; but in the case of any such certificates or opinions 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 requirement of this
          Indenture;

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

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

          (4) none of the provisions contained in this Indenture shall require
     the Trustee to expend or risk its own funds or otherwise incur personal
     financial liability in the performance of any of its duties or in the
     exercise of any of its rights or powers, if there 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.

SECTION 7.02 Certain Rights of Trustee.

     Except as otherwise provided in Section 7.01:

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

     (b) Any request, direction, order or demand of the Company mentioned herein
shall be sufficiently evidenced by a Board Resolution or an instrument signed in
the name of the


                                      -26-
<PAGE>


Company, by the President or any Vice President and by the Secretary or an
Assistant Secretary or the Treasurer or an Assistant Treasurer thereof (unless
other evidence in respect thereof is specifically prescribed herein);

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

     (d) The Trustee shall be under no obligation to exercise any of the rights
or powers vested in it by this Indenture at the request, order or direction of
any of the Securityholders, pursuant to the provisions of this Indenture, unless
such Securityholders shall have offered to the Trustee reasonable security or
indemnity against the costs, expenses and liabilities that may be incurred
therein or thereby; nothing contained herein shall, however, relieve the Trustee
of the obligation, upon the occurrence of an Event of Default with respect to a
series of the Securities (that has not been cured or waived) to exercise with
respect to Securities of that series such of the rights and powers vested in it
by this Indenture, and to 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;

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

     (f) The Trustee shall not be bound to make any investigation into the facts
or matters stated in any resolution, certificate, statement, instrument,
opinion, report, notice, request, consent, order, approval, bond, security or
other papers or documents, unless requested in writing so to do by the holders
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; and

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

SECTION 7.03 Trustee Not Responsible for Recitals or Issuance or Securities.

     (a) The recitals contained herein and in the Securities shall be taken as
the statements of the Company, and the Trustee assumes no responsibility for the
correctness of the same.


                                      -27-
<PAGE>



     (b) The Trustee makes no representations as to the validity or sufficiency
of this Indenture or of the Securities.

     (c) The Trustee shall not be accountable for the use or application by the
Company of any of the Securities or of the proceeds of such Securities, or for
the use or application of any moneys paid over by the Trustee in accordance with

     Subject to the provisions of Section 11.05, all moneys received by the
Trustee shall, until used or applied as herein provided, be held in trust for
the purposes for which they were received, but need not be segregated from other
funds except to the extent required by law. The Trustee shall be under no
liability for interest on any moneys received by it hereunder except such as it
may agree with the Company to pay thereon.

SECTION 7.06 Compensation and Reimbursement.

     (a) The Company covenants and agrees to pay to the Trustee, and the Trustee
shall be entitled to, such reasonable compensation (which shall not be limited

for all services rendered by it in the execution of the trusts hereby created
and in the exercise and performance of any of the powers and duties hereunder of
the Trustee, and, except as otherwise expressly provided herein, the Company

arise from its negligence or bad faith. The Company also covenants to indemnify
the Trustee (and its officers, agents, directors and employees) for, and to hold
it harmless against, any loss, liability or expense incurred without negligence
or bad faith on the part of the Trustee and arising out of or in connection with
the acceptance or administration of this trust, including the costs and expenses

SECTION 7.07 Reliance on Officers' Certificate.

     Except as otherwise provided in Section 7.01, whenever in the
administration of the provisions of this Indenture the Trustee shall deem it
necessary or desirable that a matter be proved or established prior to taking or
suffering or omitting to take any action hereunder, such matter (unless other
evidence in respect thereof be herein specifically prescribed) may, in the
absence of negligence or bad faith on the part of the Trustee, be deemed to be
conclusively proved and established by an Officers' Certificate delivered to the
Trustee and such certificate, in the absence of negligence or bad faith on the
part of the Trustee, shall be full warrant to the Trustee for any action taken,
suffered or omitted to be taken by it under the provisions of this Indenture
upon the faith thereof.

Company shall in all respects comply with the provisions of Section 310(b) of
the Trust Indenture Act.

SECTION 7.09 Corporate Trustee Required; Eligibility.

     There shall at all times be a Trustee with respect to the Securities issued
hereunder which shall at all times be a corporation organized and doing business

act as trustee by the Commission, authorized under such laws to exercise
corporate trust powers, having a combined capital and surplus of at least 50
million U.S. dollars ($50,000,000), and subject to supervision or examination by
Federal, State, Territorial or District of Columbia authority. If such
corporation publishes reports of condition at least annually, pursuant to law or
to the requirements of the aforesaid supervising or examining authority, then
for the purposes of this Section, the combined capital and surplus of such
corporation shall be deemed to be its combined capital and surplus as set forth
in its most recent report of condition so published. The Company may not, nor
may any Person directly or indirectly controlling, controlled by or under 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,
the Trustee shall resign immediately in the manner and with the effect specified
in Section 7.10.

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
with respect to Securities of such series by written instrument, in duplicate,
executed by order of the Board of Directors, one copy of which instrument shall
be delivered to the resigning Trustee and one copy to the successor trustee. If
no successor trustee shall have been so appointed and have accepted appointment
within 30 days after the mailing of such notice of


                                      -29-
<PAGE>

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

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

          (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,

then, in any such case, the Company may remove the Trustee with respect to all
Securities and appoint a successor trustee by written instrument, in duplicate,
executed by order of the Board of Directors, one copy of which instrument shall
be delivered to the Trustee so removed and one copy to the successor trustee,
or, unless the Trustee's duty to resign is stayed 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.

     (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 may be
appointed with respect to the Securities of one or more series or all of such
series, and at any time there shall be only one Trustee with respect to the
Securities of any particular series.

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 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 shall execute
any and all instruments for more fully and certainly vesting in and confirming
to such successor trustee

                                      -31-
<PAGE>

all such rights, powers and trusts referred to in paragraph (a) or (b) of this
Section, as the case may be.

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

     (e) Upon acceptance of appointment by a successor trustee as provided in
this Section, the Company shall transmit notice of the succession of such
trustee hereunder by mail, first class postage prepaid, to the Securityholders,
as their names and addresses appear upon the Security Register. If the Company
fails to transmit such notice within ten days after acceptance of appointment by
the successor trustee, the successor trustee shall cause such notice to be
transmitted at the expense of the Company.

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 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,
excluding any creditor relationship described in Section 311(b) of the Trust
Indenture Act. A Trustee who has resigned or been removed shall be subject to
Section 311(a) of the Trust Indenture Act to the extent included therein.

                                  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.


                                      -32-
<PAGE>


     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, 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:

          (1) 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.

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

          (3) 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.


                                      -33-
<PAGE>

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
any Person directly or indirectly controlling or controlled by or under common
control with the Company or any other obligor on the Securities of that series
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 the Trustee actually 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 a Person
directly or indirectly controlling or controlled by or under direct or indirect
common control with the Company or any such other obligor. 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
and such holder. 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.

                                   ARTICLE IX

                             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:


                                      -34-
<PAGE>


     (a) to cure any ambiguity, defect or inconsistency herein or in the
Securities of any series;

     (b) to comply with Article Ten;

     (c) to provide for uncertificated Securities in addition to or in place of
certificated Securities;

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

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

     (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.

     The Trustee is hereby authorized to 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 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,


                                      -35-
<PAGE>

(i) extend the fixed maturity of any Securities of any series, or reduce the
principal amount thereof, or 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 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 or of 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
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,
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 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 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 is
authorized or permitted by, and conforms to, the terms of this Article and that
it is proper for the Trustee under the provisions of this Article 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.


                                      -36-
<PAGE>


     Promptly after the execution by the Company and the Trustee of any
supplemental indenture pursuant to the provisions of this Section, 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.

parties, or shall prevent any sale, conveyance, transfer or other disposition of
the property of the Company or its successor or successors as an entirety, or
substantially as an entirety, to any other corporation (whether or not
affiliated with the Company or its successor or successors) authorized to
acquire and operate the same; provided, however, the Company hereby covenants

consolidation, or into which the Company shall have been merged, or by the
entity which shall have acquired such property.

and the due and punctual performance of all of the covenants and conditions of
this Indenture or established with respect to each series of the Securities
pursuant to Section 2.01 to be performed by the Company with respect to each
series, such successor entity shall succeed to and be substituted for the
Company with the same effect as if it had been named as the Company herein, and
thereupon the predecessor corporation shall be relieved of all obligations and
covenants under this Indenture and the Securities.

merger of any Person into the Company where the Company is the survivor of such

the Company).

Opinion of Counsel as conclusive evidence that any such consolidation, merger,
sale, conveyance, transfer or other disposition, and any such assumption, comply
with the provisions of this Article.

Governmental Obligations sufficient to pay at maturity or upon redemption all
such Securities of that series not theretofore delivered to the Trustee for

become due to such date of maturity or date fixed for redemption, as the case

Company) shall be discharged from such trust; and thereupon 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

SECTION 13.06 Treatment of Securities as Debt.

of this Indenture relating to such particular application or demand, no
additional certificate or opinion need be furnished.

SECTION 13.08 Payments on Business Days.

     Except as provided pursuant to Section 2.01 pursuant to a Board Resolution,
and as set forth in an Officers' Certificate, or established in one or more
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
(and premium, if any) may be made on the next succeeding Business Day with the
same force and effect as if made on the nominal date of maturity or redemption,
and no interest shall accrue for the period after such nominal date.

SECTION 13.09 Conflict with Trust Indenture Act.

     If and to the extent that any provision of this Indenture limits, qualifies
or conflicts with the duties imposed by Sections 310 to 317, inclusive, of the
Trust Indenture Act, such imposed duties shall control.

SECTION 13.10 Counterparts.

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

SECTION 13.11 Separability.

     In case any one or more of the provisions contained in this Indenture or in
the Securities of any series shall for any reason be held to be invalid, illegal
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.

SECTION 13.12 Assignment.

     The Company will have the right at all times to assign any of its rights or
obligations under this Indenture to a direct or indirect wholly owned Subsidiary
of the Company, provided that, in the event of any such assignment, the Company
will remain liable for all such obligations. Subject to the foregoing, the
Indenture is binding upon and inures to the benefit of the parties thereto and
their respective successors and assigns. This Indenture may not otherwise be
assigned by the parties thereto.
