at the rate specified with respect to that series. Subject to Section 2.01(a)(16),
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

 

8

 

such Defaulted Interest or shall make arrangements
satisfactory to the Trustee for such deposit prior to the date of the proposed
payment, such money when deposited to be held in trust for the benefit of the
Persons entitled to such Defaulted Interest as in this clause 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 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 and
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 first day of
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
Authentication.

 

The Securities shall be signed on behalf of the
Company by one of its Officers. Signatures may be in the form of a manual or
facsimile signature.

 

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

 

9

 

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

 

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”).

 

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

 

10

 

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)           Except as provided
pursuant to Section 2.01 pursuant to a Board Resolution, and set forth in
an Officers’ Certificate, or established in one or more indentures supplemental
to this Indenture, 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, other than the unredeemed portion of any such Securities being
redeemed in part. 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

 

11

 

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 cancelled by it, and no Securities
shall be issued in lieu thereof except as expressly required or permitted by
any of the provisions of this Indenture. In the absence of such request the
Trustee may dispose of canceled Securities in accordance with its standard
procedures and deliver a certificate of disposition to the Company. If the
Company shall otherwise acquire any of the Securities, however, such
acquisition shall not operate as a redemption or satisfaction of the
indebtedness represented by such Securities unless and until the same are
delivered to the Trustee for cancellation.

 

Section 2.09         Benefits of Indenture.

 

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

 

12

 

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.

 

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 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,

 

13

 

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, or if an Event of Default has occurred and is
continuing and the Company has received a request from the Depositary, this Section 2.11
shall no longer be applicable to the Securities of such series and the Company
will execute, and subject to Section 2.04, 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 2.04, 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 3

 

REDEMPTION
OF SECURITIES AND SINKING FUND PROVISIONS

 

Section 3.01         Redemption.

 

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

 

Section 3.02         Notice of Redemption.

 

(a)           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 any right the
Company reserved for itself to do so pursuant to Section 2.01 hereof, 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

 

14

 

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 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 (unless a shorter notice shall be satisfactory
to the Trustee) 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
an Officer, 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 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.

 

15

 

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 and (ii) may apply as a credit
Securities of a series that have been redeemed either at the election of the
Company pursuant to the terms of such Securities or through the application of
permitted optional sinking fund payments pursuant to the terms of such
Securities, in each case in satisfaction of all or any part of any sinking fund
payment with respect to the Securities of such series required to be made
pursuant to the terms of such Securities 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

 

16

 

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 (unless a
shorter period shall be satisfactory to the Trustee), 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 4

 

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 any officer authorized to sign an
Officers’ Certificate 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. The Company initially appoints the
Corporate Trust Office of the Trustee located in the Borough of Manhattan, the
City of New York as its paying agent with respect to the Securities.

 

17

 

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 the Company or any paying agent to the Trustee, the Company or
such paying agent shall be released from all further liability with respect to
such money.

The Company, whenever
necessary to avoid or fill a vacancy in the office of Trustee, will appoint, in
the manner provided in Section 7.10, a Trustee, so that there shall at all
times be a Trustee hereunder.

 

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 Person unless the provisions of Article Ten hereof are complied
with.

ARTICLE 6

 

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 such default continues for a period
of 90 days; provided, however, that a valid extension of

 

20

 

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 (other than an
Event of Default specified in clause (4) or clause (5) above), 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 (and premium, if any, on)
and accrued and unpaid interest on all the Securities of that series to be due
and payable immediately, and upon any such declaration the same shall become
and shall be immediately due and payable. If an Event of Default specified in
clause (4) or clause (5) above occurs, the principal of and accrued
and unpaid interest on all the Securities of that series shall automatically be
immediately due and payable without any declaration or other act on the part of
the Trustee or the holders of the Securities.

 

(c)           At any time after the principal of (and
premium, if any, on) and accrued and unpaid interest on 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

 

21

 

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

 

(b)           If the Company shall fail to pay such amounts
forthwith upon such demand, the Trustee, in its own name and as trustee of an
express trust, shall be entitled and empowered to institute any action or
proceedings at law or in equity for the collection of the sums so due and
unpaid, and may prosecute any such action or proceeding to judgment or final

 

22

 

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 or equity 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 affecting 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, 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 or Property Collected.

 

Any moneys or property 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

 

23

 

the Trustee and, in case of
the distribution of such moneys or property on account of principal (or
premium, if any) or interest, upon presentation of the Securities of that
series, and notation thereon of the payment, if only partially paid, and upon
surrender thereof if fully paid:

 

FIRST: To the payment of
reasonable costs and expenses of collection and of all amounts payable to the
Trustee under Section 7.06;

 

SECOND: To the payment of
the amounts then due and unpaid upon Securities of such series for principal
(and premium, if any) and interest, in respect of which or for the benefit of
which such money has been collected, ratably, without preference or priority of
any kind, according to the amounts due and payable on such Securities for
principal (and premium, if any) and interest, respectively; and

 

THIRD: To the payment of the
remainder, if any, to the Company or any other Person lawfully entitled thereto
as requested by the Company.

 

Section 6.04         Limitation
on Suits.

 

No holder of any Security of
any series shall have any right by virtue or by availing of any provision of
this Indenture to institute any suit, action or proceeding in equity or at law
upon or under or with respect to this Indenture or for the appointment of a
receiver or trustee, or for any other remedy hereunder, unless (i) such
holder previously shall have given to the Trustee written notice of an Event of
Default and of the continuance thereof with respect to the Securities of such
series specifying such Event of Default, as hereinbefore provided; (ii) the
holders of not less than 25% in aggregate principal amount of the Securities of
such series then Outstanding shall have made written request upon the Trustee
to institute such action, suit or proceeding in its own name as Trustee
hereunder; (iii) such holder or holders shall have offered to the Trustee
such reasonable indemnity as it may require against the costs, expenses and
liabilities to be incurred therein or thereby; (iv) the Trustee for 90
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 90 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 or any other provisions of this Indenture, the
right of any holder of any Security to receive payment of the principal of (and
premium, if any) and interest on such Security, as therein provided, on or after
the respective due dates expressed in such Security (or in the case of
redemption, on the redemption date), or to institute suit for the enforcement
of any such payment on or after such respective dates or redemption date, shall
not be impaired or affected without the consent of such holder and by accepting
a Security hereunder it is expressly understood, intended and covenanted by the
taker and holder of every Security of such series with every other such taker
and holder and the Trustee, that no one or more holders of Securities of such
series shall have any right in any manner whatsoever by virtue or by availing
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

 

24

 

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 an 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 8.04, shall have the
right to direct the time, method and place of conducting any proceeding for any
remedy available to the Trustee, or exercising any trust or power conferred on
the Trustee with respect to such series; provided, however, that such direction
shall not be in conflict with any rule of law or with this Indenture.
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, subject to the Trustee’s duties under the Trust
Indenture Act, would involve the Trustee in personal liability or might be
unduly prejudicial to the Securityholders not involved in the proceeding. The
holders of a majority in aggregate principal amount of the Securities of any
series at the time Outstanding affected thereby, determined in accordance with Section 8.04,
may on behalf of the holders of all of the Securities of such series waive any
past default in the performance of any of the covenants contained herein or
established pursuant to Section 2.01 with respect to such series and its
consequences, except a default in the payment of the principal of, or premium,
if any, or interest on, any of the Securities of that series as and when the
same shall become due by the terms of such Securities otherwise than by
acceleration (unless such default has been cured and a sum sufficient to pay
all matured installments of interest and principal and any premium has been
deposited with the Trustee (in accordance with Section 6.01(c)). Upon any
such waiver, the default covered thereby shall be deemed to be cured for all
purposes of this Indenture and the Company, the Trustee and the holders of the
Securities of such series shall be restored to their former positions and
rights hereunder, respectively; but no such waiver shall extend to any
subsequent or other default or impair any right consequent thereon.

 

25

 

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.

 

ARTICLE 7

 

CONCERNING
THE TRUSTEE

 

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:

 

(i)            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:

 

(A)          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

 

26

 

(B)          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;

 

(ii)           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;

 

(iii)         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

 

(iv)          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 conclusively 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 Company by any authorized
officer of the Company (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

 

27

 

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.

 

In addition, the Trustee shall not be deemed to have
knowledge of any Default or Event of Default except (1) any Event of
Default occurring pursuant to Sections 6.01(a)(1), 6.01(a)(2) and 4.01
hereof or (2) any Default or Event of Default of which the Trustee shall
have received written notification in the manner set forth in this Indenture or
a Responsible Officer of the Trustee shall have obtained actual knowledge.
Delivery of reports, information and documents to the Trustee under Section 5.03
is for informational purposes only and the information and the Trustee’s
receipt of the foregoing shall not constitute constructive notice of any
information contained therein, or determinable from information contained
therein including the Company’s compliance with any of their covenants
thereunder (as to which the Trustee is entitled to rely conclusively on an
Officers’ Certificate).

 

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.

 

28

 

(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 any provision of this Indenture or established
pursuant to Section 2.01, or for the use or application of any moneys
received by any paying agent other than the Trustee.

 

Section 7.04         May Hold Securities.

 

The Trustee or any paying agent or Security Registrar,
in its individual or any other capacity, may become the owner or pledgee of
Securities with the same rights it would have if it were not Trustee, paying
agent or Security Registrar.

 

Section 7.05         Moneys Held in Trust.

 

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 by any provision of law in regard to
the compensation of a trustee of an express trust) as the Company and the
Trustee may from time to time agree in writing, 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 will pay or
reimburse the Trustee upon its request for all reasonable expenses,
disbursements and advances incurred or made by the Trustee in accordance with
any of the provisions of this Indenture (including the reasonable compensation
and the expenses and disbursements of its counsel and of all Persons not
regularly in its employ), except any such expense, disbursement or advance as
may arise from its negligence or bad faith and except as the Company and
Trustee may from time to time agree in writing. 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 reasonable costs and expenses of defending itself against any claim of
liability in the premises.

 

(b)           The obligations of the Company under
this Section to compensate and indemnify the Trustee and to pay or
reimburse the Trustee for reasonable expenses, disbursements and advances shall
constitute additional indebtedness hereunder. Such additional indebtedness
shall be secured by a lien prior to that of the Securities upon all property
and funds

 

29

 

held or collected by the Trustee as such, except funds
held in trust for the benefit of the holders of particular Securities.

 

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 reasonably 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.

 

Section 7.08         Disqualification; Conflicting Interests.

 

If the Trustee has or shall acquire any “conflicting
interest” within the meaning of Section 310(b) of the Trust Indenture
Act, the Trustee and the 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 under the laws of the United States of America or
any state or territory thereof or of the District of Columbia, or a corporation
or other Person permitted to act as trustee by the Securities and Exchange
Commission, authorized under such laws to exercise corporate trust powers,
having a combined capital and surplus of at least fifty 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 or other Person 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 or other Person
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.

 

30

 

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 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:

 

(i)            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

 

(ii)           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

 

(iii)         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 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.

 

31

 

(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 (i) 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, (ii) 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 (iii) 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.

 

32

 

(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 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.

 

Section 7.14         Notice of Default

 

If any Default or any Event of Default occurs and is
continuing and if such Default or Event of Default is known to a Responsible
Officer of the Trustee, the Trustee shall mail to each Securityholder in the
manner and to the extent provided in Section 313(c) of the Trust
Indenture Act notice of the Default or Event of Default within 45 days after it
occurs and becomes known to the Trustee, unless such Default or Event of Default
has been cured; provided, however,
that, except in the case of a default in the payment of the principal of (or
premium, if any) or interest on any Security, the Trustee shall be protected in
withholding such notice if and so long as the board of directors, the executive
committee or a trust committee of directors and/or Responsible

 

33

 

Officers of the Trustee
in good faith determine that the withholding of such notice is in the interest
of the Securityholders.

 

ARTICLE 8

 

CONCERNING
THE SECURITYHOLDERS

 

Section 8.01         Evidence of Action by Securityholders.

 

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

 

If the Company shall solicit from the Securityholders
of any series any request, demand, authorization, direction, notice, consent,
waiver or other action, the Company may, at its option, as evidenced by an
Officers’ Certificate, fix in advance a record date for such series for the
determination of Securityholders entitled to give such request, demand,
authorization, direction, notice, consent, waiver or other action, but the
Company shall have no obligation to do so. If such a record date is fixed, such
request, demand, authorization, direction, notice, consent, waiver or other
action may be given before or after the record date, but only the
Securityholders of record at the close of business on the record date shall be
deemed to be Securityholders for the purposes of determining whether
Securityholders of the requisite proportion of Outstanding Securities of that
series have authorized or agreed or consented to such request, demand,
authorization, direction, notice, consent, waiver or other action, and for that
purpose the Outstanding Securities of that series shall be computed as of the
record date; provided, however, that no such authorization, agreement or
consent by such Securityholders on the record date shall be deemed effective
unless it shall become effective pursuant to the provisions of this Indenture
not later than six months after the record date.

 

Section 8.02         Proof of Execution by Securityholders.

 

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

 

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

 

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

 

34

 

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

 

Section 8.03         Who May be Deemed Owners.

 

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

 

Section 8.04         Certain Securities Owned by Company
Disregarded.

 

In determining whether the holders of the requisite aggregate principal
amount of Securities of a particular series have concurred in any direction,
consent or 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. 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

 

35

 

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 9

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

if such covenants, restrictions, conditions or provisions are to be for the
benefit of less than all series of Securities, stating that such covenants,
restrictions, conditions or provisions are expressly being included solely for
the benefit of such series), to make the occurrence, or the occurrence and the
continuance, of a default in any such additional covenants, restrictions,
conditions or provisions an Event of Default, or to surrender any right or
power herein conferred upon the Company;

 

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

 

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

 

(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

36

 

(i)            to
comply with any requirements of the Securities and Exchange Commission or any
successor in connection with the qualification of this Indenture under the
Trust Indenture Act.

 

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 a Board Resolution, 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, (a) 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 (b) 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.

 

37

 

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 securities 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, 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, will be entitled to receive and will be
fully protected in relying upon an Officers’ Certificate and an Opinion of
Counsel stating 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 Officers’
Certificate or Opinion of Counsel need not be provided in connection with the
execution of a supplemental indenture that establishes the terms of a series of
Securities pursuant to Section 2.01 hereof.

 

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

Except as provided pursuant to Section 2.01 pursuant to a Board
Resolution, and set forth in an Officers’ Certificate, or established in one or
more indentures supplemental to this Indenture, nothing contained in this
Indenture shall prevent any consolidation or merger of the Company with or into
any other Person (whether or not affiliated with the Company) or

successive consolidations or mergers in which the
Company or its successor or successors shall be a party or 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 and agrees that, upon any
such consolidation or merger (in each case, if the Company is not the survivor
of such transaction), sale, conveyance, transfer or other disposition, the due
and punctual payment of the principal of (premium, if any) and interest on all
of the Securities of all series in accordance with the terms of each series,
according to their tenor, and the due and punctual performance and observance
of all the covenants and conditions of this Indenture with respect to each
series or established with respect to such series pursuant to Section 2.01
to be kept or performed by the Company shall be expressly assumed, by
supplemental indenture (which shall conform to the provisions of the Trust
Indenture Act, as then in effect) reasonably satisfactory in form to the
Trustee executed and delivered to the Trustee by the entity formed by such
consolidation, or into which the Company shall have been merged, or by the
entity which shall have acquired such property.

 

Section 10.02       Successor Entity Substituted.

 

(a)           In
case of any such consolidation, merger, sale, conveyance, transfer or other
disposition and upon the assumption by the successor entity by supplemental
indenture, executed and delivered to the Trustee and satisfactory in form to
the Trustee, of the obligations set forth under Section 10.01 on all of
the Securities of all series Outstanding, 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.

 

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

 

(c)           Nothing
contained in this Article shall require any action by the Company in the
case of a consolidation or merger of any Person into the Company where the
Company is the survivor of such transaction, or the acquisition by the Company,
by purchase or otherwise, of all or any part of the property of any other
Person (whether or not affiliated with the Company).

 

Section 10.03       Evidence of Consolidation, Etc. to
Trustee.

 

The Trustee, subject to the provisions of Section 7.01, may
receive an Officers’ Certificate or an 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.

If at any time: (a) the Company shall have delivered to the

replaced or paid as provided in Section 2.07 and Securities for whose

delivered to the Trustee for cancellation, including principal (and premium, if
any) and interest due or to become due to such date of maturity or date fixed
for redemption, as the case may be, and if the Company shall also pay or cause
to be paid all other sums payable hereunder with respect to such series by the
Company then this Indenture shall thereupon cease to be of further effect with
respect to such series except for the provisions of Sections 2.03, 2.05, 2.07,
4.01, 4.02, 4.03 and 7.10, that shall survive until the date of maturity or
redemption date, as the case may be, and Sections 7.06 and 11.05, that shall
survive to such date and thereafter, and the Trustee, on demand of the Company
and at the cost and expense of the Company shall execute proper instruments

series.

 

Section 11.02       Discharge of Obligations.

amount of Governmental Obligations sufficient to pay at maturity or upon
redemption all such Securities of that series not theretofore delivered to the
Trustee for cancellation, including principal (and premium, if any) and
interest due or to become due to such date of maturity or date fixed for
redemption, as the case may be, and if the Company shall also pay or cause to
be paid all other sums payable hereunder by the Company with respect to such
series, then after the date such moneys or Governmental Obligations, as the
case may be, are deposited with the Trustee the obligations of the Company
under this Indenture with respect to such series shall cease to be of further
effect except for the provisions of Sections 2.03, 2.05, 2.07, 4,01, 4.02,
4,03, 7.06, 7.10 and 11.05 hereof that shall survive until such Securities

Section 11.03       Deposited Moneys to be Held in Trust.

 

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

 

Section 11.04       Payment of Moneys Held by Paying Agents.

 

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

 

Section 11.05       Repayment to Company.

 

Any moneys or Governmental Obligations deposited with any paying agent
or the Trustee, or then held by the Company, in trust for payment of principal
of or premium, if any, or interest on the Securities of a particular series
that are not applied but remain unclaimed by the holders of such Securities for
at least two years after the date upon which the principal of (and premium, if
any) or interest on such Securities shall have respectively become due and
payable, or such other shorter period set forth in applicable escheat or
abandoned or unclaimed property law, shall be repaid to the Company on May 31
of each year or upon the Company’s request or (if then held by the 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 a general creditor, look

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:

 

8

 

(1) The
Company may make payment of any Defaulted Interest on Securities to the Persons
in whose names such Securities (or their respective Predecessor Securities) are
registered at the close of business on a special record date for the payment of
such Defaulted Interest, which shall be fixed in the following manner: the Company
shall notify the Trustee in writing of the amount of Defaulted Interest
proposed to be paid on each such Security and the date of the proposed payment,
and at the same time the Company shall deposit with the Trustee an amount of
money equal to the aggregate amount proposed to be paid in respect of such
Defaulted Interest or shall make arrangements satisfactory to the Trustee for
such deposit prior to the date of the proposed payment, such money when
deposited to be held in trust for the benefit of the Persons entitled to such
Defaulted Interest as in this clause 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 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 and
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 first day of
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 Authentication.

 

The Securities shall be signed on behalf of the
Company by one of its Officers. Signatures may be in the form of a manual or
facsimile signature.

 

9

 

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

 

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

 

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”).

 

10

 

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) Except
as provided pursuant to Section 2.01 pursuant to a Board Resolution, and
set forth in an Officers’ Certificate, or established in one or more indentures
supplemental to this Indenture, 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, other than the unredeemed portion of any such Securities being
redeemed in part. 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.

 

11

 

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 cancelled by it, and no Securities
shall be issued in lieu thereof except as expressly required or permitted by
any of the provisions of this Indenture. 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

 

12

 

acquisition shall not
operate as a redemption or satisfaction of the indebtedness represented by such
Securities unless and until the same are delivered to the Trustee for
cancellation.

 

Section 2.09         Benefits
of Indenture.

 

Nothing in this Indenture or in the Securities,
express or implied, shall give or be construed to give to any Person, other
than the parties hereto and the holders of the Securities (and, with respect to
the provisions of Article Fourteen, the holders of any indebtedness of the
Company to which the Securities of any series are subordinated) 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 any indebtedness of the Company to which the Securities of any
series are subordinated).

 

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

 

13

 

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 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, or if an Event of Default has occurred and is continuing and the
Company has received a request from the Depositary, this Section 2.11
shall no longer be applicable to the Securities of such series and the Company
will execute, and subject to Section 2.04, 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 2.04, 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 3

 

REDEMPTION
OF SECURITIES AND SINKING FUND PROVISIONS

 

Section 3.01         Redemption.

 

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

 

Section 3.02         Notice of Redemption.

 

(a)           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 any right the
Company reserved for itself to do so pursuant to Section 2.01 hereof, 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 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 (unless a shorter notice shall be satisfactory to the Trustee) in
advance of the date fixed for redemption as to the aggregate principal amount
of

 

15

 

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 an Officer,
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 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

 

16

 

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 and (ii) may apply as a credit Securities of a
series that have been redeemed either at the election of the Company pursuant
to the terms of such Securities or through the application of permitted
optional sinking fund payments pursuant to the terms of such Securities, in
each case in satisfaction of all or any part of any sinking fund payment with
respect to the Securities of such series required to be made pursuant to the
terms of such Securities 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 (unless a shorter period shall be
satisfactory to the Trustee), 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 4

 

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

 

17

 

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 any officer authorized to sign an Officers’ Certificate 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. The Company
initially appoints the Corporate Trust Office of the Trustee located in the Borough
of Manhattan, the City of New York as its paying agent with respect to the
Securities.

 

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

 

18

 

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 the Company or any paying agent to the Trustee, the Company or
such paying agent shall be released from all further liability with respect to
such money.

 

Section 4.04         Appointment to Fill Vacancy in Office
of Trustee.

 

The Company, whenever necessary to avoid or fill a
vacancy in the office of Trustee, will appoint, in the manner provided in Section 7.10,
a Trustee, so that there shall at all times be a Trustee hereunder.

 

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 Person 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 such default continues 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.

 

21

 

(b)           In each and every such case (other than
an Event of Default specified in clause (4) or clause (5) above),
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 (and premium, if any, on)
and accrued and unpaid interest on all the Securities of that series to be due
and payable immediately, and upon any such declaration the same shall become
and shall be immediately due and payable. If an Event of Default specified in
clause (4) or clause (5) above occurs, the principal of and accrued
and unpaid interest on all the Securities of that series shall automatically be
immediately due and payable without any declaration or other act on the part of
the Trustee or the holders of the Securities.

 

(c)           At any time after the principal of (and
premium, if any, on) and accrued and unpaid interest on 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 (and premium, if any, on) and accrued and unpaid
interest 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 (i) in
case it shall default in the payment of any installment of interest on any of
the Securities of a series, or in 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 (ii) in case it shall default in the
payment of the principal of (or premium, if any, on) any of the

 

22

 

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

 

(b)           If the Company shall fail to pay such
amounts forthwith upon such demand, the Trustee, in its own name and as trustee
of an express trust, shall be entitled and empowered to institute any action or
proceedings at law or in equity for the collection of the sums so due and
unpaid, and may prosecute any such action or proceeding to judgment or final
decree, and may enforce any such judgment or final decree against the Company
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 or equity 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 affecting 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,

 

23

 

either at law or in
equity or in bankruptcy or otherwise, whether for the specific enforcement of
any covenant or agreement contained in the Indenture or in aid of the exercise
of any power granted in this Indenture, or to enforce any other legal or
equitable right vested in the Trustee by this Indenture or by law.

 

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

 

Section 6.03         Application of Moneys or Property
Collected.

 

Any moneys or property 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 moneys or property on account
of principal (or premium, if any) or interest, upon presentation of the
Securities of that series, and notation thereon of the payment, if only
partially paid, and upon surrender thereof if fully paid:

 

FIRST: To the payment of reasonable costs and expenses
of collection and of all amounts payable to the Trustee under Section 7.06;

 

SECOND:  To the
payment of all indebtedness of the Company to which such series of Securities
is subordinated to the extent required by Section 7.06 and Article Fourteen;

 

THIRD: To the payment of the amounts then due and
unpaid upon Securities of such series for principal (and premium, if any) and
interest, in respect of which or for the benefit of which such money has been
collected, ratably, without preference or priority of any kind, according to
the amounts due and payable on such Securities for principal (and premium, if
any) and interest, respectively; and

 

FOURTH: To the payment of the remainder, if any, to
the Company or any other Person lawfully entitled thereto, as requested by the
Company.

 

Section 6.04         Limitation on Suits.

 

No holder of any Security of any series shall have any
right by virtue or by availing of any provision of this Indenture to institute
any suit, action or proceeding in equity or at law upon or under or with
respect to this Indenture or for the appointment of a receiver or trustee, or
for any other remedy hereunder, unless (i) such holder previously shall
have given to the Trustee written notice of an Event of Default and of the
continuance thereof with respect to the Securities of such series specifying
such Event of Default, as hereinbefore provided; (ii) the holders of not less
than 25% in aggregate principal amount of the Securities of such series then
Outstanding shall have made written request upon the Trustee to institute such
action, suit or proceeding in its own name as Trustee hereunder; (iii) such
holder or holders shall have offered to the Trustee such reasonable indemnity
as it may require against the costs, expenses and liabilities to be incurred
therein or thereby; (iv) the Trustee for 90 days after its receipt of such
notice, request and offer of

 

24

 

indemnity, shall have
failed to institute any such action, suit or proceeding and (v) during
such 90 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 or any other provisions of this Indenture, the right of any holder of
any Security to receive payment of the principal of (and premium, if any) and
interest on such Security, as therein provided, on or after the respective due
dates expressed in such Security (or in the case of redemption, on the
redemption date), or to institute suit for the enforcement of any such payment
on or after such respective dates or redemption date, shall not be impaired or
affected without the consent of such holder and by accepting a Security
hereunder it is expressly understood, intended and covenanted by the taker and
holder of every Security of such series with every other such taker and holder
and the Trustee, that no one or more holders of Securities of such series shall
have any right in any manner whatsoever by virtue or by availing 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 an 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 8.04, shall have the right to direct the time,
method and place of conducting any proceeding for any remedy available to the
Trustee, or exercising any trust or power conferred on the Trustee with respect
to such series; provided, however, that such direction shall not be in conflict
with any rule of law or with this Indenture. 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

 

25

 

Trustee, determine that
the proceeding so directed, subject to the Trustee’s duties under the Trust
Indenture Act, would involve the Trustee in personal liability or might be
unduly prejudicial to the Securityholders not involved in the proceeding. The
holders of a majority in aggregate principal amount of the Securities of any
series at the time Outstanding affected thereby, determined in accordance with Section 8.04,
may on behalf of the holders of all of the Securities of such series waive any
past default in the performance of any of the covenants contained herein or
established pursuant to Section 2.01 with respect to such series and its
consequences, except a default in the payment of the principal of, or premium,
if any, or interest on, any of the Securities of that series as and when the
same shall become due by the terms of such Securities otherwise than by
acceleration (unless such default has been cured and a sum sufficient to pay
all matured installments of interest and principal and any premium has been
deposited with the Trustee (in accordance with Section 6.01(c)). Upon any
such waiver, the default covered thereby shall be deemed to be cured for all
purposes of this Indenture and the Company, the Trustee and the holders of the
Securities of such series shall be restored to their former positions and
rights hereunder, respectively; but no such waiver shall extend to any
subsequent or other default or impair any right consequent thereon.

 

Section 6.07         Undertaking to Pay Costs.

 

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

CONCERNING
THE TRUSTEE

 

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

 

26

 

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:

 

(i)            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:

 

(A)          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

 

(B)          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;

 

(ii)           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;

 

(iii)         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

 

(iv)          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.

 

27

 

Section 7.02         Certain Rights of Trustee.

 

Except as otherwise provided in Section 7.01:

 

(a)           The Trustee may rely conclusively 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 Company by any authorized
officer of the Company (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

 

28

 

(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.

 

In addition, the Trustee shall not be deemed to have
knowledge of any Default or Event of Default except (1) any Event of
Default occurring pursuant to Sections 6.01(a)(1), 6.01(a)(2) and 4.01
hereof or (2) any Default or Event of Default of which the Trustee shall
have received written notification in the manner set forth in this Indenture or
a Responsible Officer of the Trustee shall have obtained actual knowledge.
Delivery of reports, information and documents to the Trustee under Section 5.03
is for informational purposes only and the information and the Trustee’s
receipt of the foregoing shall not constitute constructive notice of any
information contained therein, or determinable from information contained
therein including the Company’s compliance with any of their covenants
thereunder (as to which the Trustee is entitled to rely conclusively on an
Officers’ Certificate).

 

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.

 

(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 any provision of this Indenture or
established pursuant to Section 2.01, or for the use or application of any
moneys received by any paying agent other than the Trustee.

 

Section 7.04         May Hold Securities.

 

The Trustee or any paying agent or Security Registrar,
in its individual or any other capacity, may become the owner or pledgee of
Securities with the same rights it would have if it were not Trustee, paying
agent or Security Registrar.

 

Section 7.05         Moneys Held in Trust.

 

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.

 

29

 

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 by any provision of law in regard to the
compensation of a trustee of an express trust) as the Company and the Trustee
may from time to time agree in writing, 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 will pay or reimburse the Trustee upon
its request for all reasonable expenses, disbursements and advances incurred or
made by the Trustee in accordance with any of the provisions of this Indenture
(including the reasonable compensation and the expenses and disbursements of
its counsel and of all Persons not regularly in its employ), except any such
expense, disbursement or advance as may arise from its negligence or bad faith
and except as the Company and Trustee may from time to time agree in writing.
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 reasonable costs and expenses of
defending itself against any claim of liability in the premises.

 

(b)           The obligations of the Company under
this Section to compensate and indemnify the Trustee and to pay or
reimburse the Trustee for reasonable expenses, disbursements and advances shall
constitute indebtedness of the Company to which the Securities are
subordinated. Such additional indebtedness shall be secured by a lien prior to
that of the Securities upon all property and funds held or collected by the Trustee
as such, except funds held in trust for the benefit of the holders of
particular Securities.

 

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 reasonably 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.

 

Section 7.08         Disqualification; Conflicting Interests.

 

If the Trustee has or shall acquire any “conflicting
interest” within the meaning of Section 310(b) of the Trust Indenture
Act, the Trustee and the Company shall in all respects comply with the
provisions of Section 310(b) of the Trust Indenture Act.

 

30

 

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 under the laws of the United States of America or
any state or territory thereof or of the District of Columbia, or a corporation
or other Person permitted to act as trustee by the Securities and Exchange
Commission, authorized under such laws to exercise corporate trust powers,
having a combined capital and surplus of at least fifty 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 or other Person 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 or other Person
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
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:

 

(i)            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

 

(ii)           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

 

31

 

(iii)         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 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 (i) shall contain such provisions as shall be
necessary or desirable to transfer and confirm

 

32

 

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, (ii) 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 (iii) 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 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

 

33

 

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.

 

Section 7.14         Notice of Default

 

If any Default or any Event of Default occurs and is
continuing and if such Default or Event of Default is known to a Responsible
Officer of the Trustee, the Trustee shall mail to each Securityholder in the
manner and to the extent provided in Section 313(c) of the Trust
Indenture Act notice of the Default or Event of Default within 45 days after it
occurs and becomes known to the Trustee, unless such Default or Event of
Default has been cured; provided, however,
that, except in the case of a default in the payment of the principal of (or
premium, if any) or interest on any Security, the Trustee shall be protected in
withholding such notice if and so long as the board of directors, the executive
committee or a trust committee of directors and/or Responsible Officers of the
Trustee in good faith determine that the withholding of such notice is in the
interest of the Securityholders.

 

ARTICLE 8

 

CONCERNING
THE SECURITYHOLDERS

 

Section 8.01         Evidence of Action by Securityholders.

 

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

 

If the Company shall solicit from the Securityholders
of any series any request, demand, authorization, direction, notice, consent,
waiver or other action, the Company may, at its option, as evidenced by an
Officers’ Certificate, fix in advance a record date for such series for the
determination of Securityholders entitled to give such request, demand,
authorization, direction, notice, consent, waiver or other action, but the
Company shall have no obligation to do so. If such a record date is fixed, such
request, demand, authorization, direction, notice, consent,

 

34

 

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:

 

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

 

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

 

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

 

Section 8.03         Who May be Deemed Owners.

 

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

 

Section 8.04         Certain Securities Owned by Company
Disregarded.

 

In determining whether the holders of the requisite
aggregate principal amount of Securities of a particular series have concurred
in any direction, consent or 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

 

35

 

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. 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 9

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:

inconsistency herein or in the Securities of any series;

 

(b)           to comply with Article Ten;

conditions or provisions relating to the Company for the benefit of the holders
of all or any series of Securities (and if such covenants, restrictions,
conditions or provisions are to be for the benefit of less than all series of
Securities, stating that such covenants, restrictions, conditions or provisions
are expressly being included solely for the benefit of such series), to make
the occurrence, or the occurrence and the continuance, of a default in any such
additional covenants, restrictions, conditions or provisions an Event of
Default, or to surrender any right or power herein conferred upon the Company;

 

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

 

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

 

(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;

 

(h)           to evidence and provide for the
acceptance of appointment hereunder by a successor trustee; or

 

(i)            to comply with any requirements of the
Securities and Exchange Commission or any successor in connection with the
qualification of this Indenture under the Trust Indenture Act.

 

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 a Board Resolution,
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

 

37

 

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, (a) 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 (b) 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 securities 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, 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, will be
entitled to receive and will be fully protected in relying upon an Officers’
Certificate and an Opinion of Counsel stating 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,

 

38

 

that such Officers’ Certificate or Opinion of Counsel
need not be provided in connection with the execution of a supplemental
indenture that establishes the terms of a series of Securities pursuant to Section 2.01
hereof.

 

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

contained in this Indenture shall prevent any consolidation or merger of the
Company with or into any other Person (whether or not affiliated with the Company)
or successive consolidations or mergers in which the Company or its successor
or successors shall be a party or 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,

by the successor entity by supplemental indenture, executed and delivered to
the Trustee and satisfactory in form to the Trustee, of the obligations set
forth under Section 10.01 on all of the Securities of all series
Outstanding, such successor entity shall succeed to and be substituted for the
Company with the same effect as if it had been

 

39

 

named as the Company herein, and thereupon the
predecessor corporation shall be relieved of all obligations and covenants
under this Indenture and the Securities.

 

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

all or any part of the property of any other Person (whether or not affiliated
with the Company).

Article.

interest due or to become due to such date of maturity or date fixed for
redemption, as the case may be, and if the Company shall also pay or cause to
be paid all other sums payable hereunder by the Company with respect to such
series, then after the date such moneys or Governmental Obligations, as the
case may be, are deposited with the Trustee the obligations of the Company
under this Indenture with respect to such series shall cease to be of further
effect except for the provisions of Sections 2.03, 2.05, 2.07, 4,01, 4.02,
4,03, 7.06, 7.10 and 11.05 hereof that shall survive until such Securities

become due and payable, or such other shorter period set forth in applicable
escheat or abandoned or unclaimed property law, shall be repaid to the Company
on May 31 of each year or upon the Company’s request or (if then held by
