Trustee at or prior to the delivery of the Officers’ Certificate of the Company
setting forth the terms of the series.

 

Securities of any
particular series may be issued at various times, with different dates on which

Section 2.02                            Form of Securities and
Trustee’s Certificate.

 

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

 

Section 2.03                            Denominations: Provisions for
Payment.

 

The Securities shall be
issuable as registered Securities and in the denominations of one thousand U.S.
dollars ($1,000) or any integral multiple thereof, subject to Section 2.01(10).
The Securities of a particular series shall bear interest payable on the dates
and at the rate specified

 

7

 

with respect to
that series. The principal of and the interest on the Securities of any series,
as well as any premium thereon in case of redemption thereof prior to maturity,
shall be payable in the coin or currency of the United States of America that
at the time is legal tender for public and private debt, at the office or
agency of the Company maintained for that purpose in the Borough of Manhattan,
the City and State of New York. Each Security shall be dated the date of its
authentication. Interest on the Securities shall be computed on the basis of a
360-day year composed of twelve 30-day months.

 

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

 

Any interest on any
Security that is payable, but is not punctually paid or duly provided for, on
any Interest Payment Date for Securities of the same series (herein called “Defaulted
Interest”) shall forthwith cease to be payable to the registered holder on the
relevant regular record date by virtue of having been such holder; and such
Defaulted Interest shall be paid by the Company, at its election, as provided
in clause (1) or clause (2) below:

 

(1)                                 The Company may make payment of any
Defaulted Interest on Securities to the Persons in whose names such Securities
(or their respective Predecessor Securities) are registered at the close of
business on a special record date for the payment of such Defaulted Interest,
which shall be fixed in the following manner: the Company shall notify the
Trustee in writing of the amount of Defaulted Interest proposed to be paid on
each such Security and the date of the proposed payment, and at the same time
the Company shall deposit with the Trustee an amount of money equal to the
aggregate amount proposed to be paid in respect of such 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

 

8

 

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 Authentications.

 

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.

 

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

 

9

 

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
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

 

10

 

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 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

 

11

 

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. On
request of the Company at the time of such surrender, the Trustee shall deliver
to the Company canceled Securities held by the Trustee. In the absence of such
request the Trustee may dispose of canceled Securities in accordance with its
standard procedures and deliver a certificate of disposition to the Company. If
the Company shall otherwise acquire any of the Securities, however, such
acquisition shall not operate as a 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
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

 

12

 

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, 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

 

14

 

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.

 

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).

 

15

 

(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 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.

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.
Payments of principal on the Securities may be made at the time provided herein
and established with respect to such Securities by U.S. dollar check drawn on
and mailed to the address of the Securityholder entitled thereto as such
address shall appear in the Security Register, or U.S. dollar wire transfer to,
a U.S. dollar account (such wire transfer to be made only to a Securityholder
of an aggregate principal amount of Securities of the applicable series in
excess of U.S. $2,000,000 and only if such Securityholder shall have furnished
wire instructions to the Trustee no later than 15 days prior to the relevant
payment date). Payments of interest on the Securities may be made at the time
provided herein and established with respect to such Securities by U.S. dollar
check mailed to the address of the Securityholder entitled thereto as such
address shall appear in the Security Register, or U.S. dollar wire transfer to,

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.

 

Section 4.03                            Paying Agents.

paying agents for all or any series of the Securities, other than the Trustee,
the Company will cause each such paying agent to execute

 

17

 

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.

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.

(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 

 

20

 

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 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 

 

21

 

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
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.

 

22

 

(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 Collected.

 

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

 

23

 

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.

 

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 Section, each and every
Securityholder and the Trustee shall be entitled to such relief as can be given
either at law or in equity.

 

24

 

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.

 

Section 6.07                            Undertaking to Pay Costs.

 

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

 

25

 

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

 

(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

 

26

 

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 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

 

27

 

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 exclusively 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

 

28

 

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

 

29

 

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. 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

 

30

 

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.

 

(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.

 

31

 

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.

 

(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

 

32

 

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, including the
administration of the trust created by this Indenture, 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, 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, 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.

 

34

 

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 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.

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:

 

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

 

(b)                                  to comply with Article Ten;

in addition to or in place of certificated Securities;

 

(d)                                  to add to the covenants, restrictions,
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.

 

36

 

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.

 

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

 

37

 

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,
may receive an Officers’ Certificate or an Opinion of Counsel as conclusive
evidence that any supplemental indenture executed pursuant to this Article is
authorized or permitted by, and conforms to, the terms of this Article and
that it is proper for the Trustee under the provisions of this Article to
join in the execution thereof; provided, however, that such 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.

 

ARTICLE 10

SUCCESSOR ENTITY

 

Section 10.01                     Company May Consolidate,
Etc.

 

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, (a) the Company hereby
covenants and agrees that, upon any such consolidation or merger (in each case,
if the

 

38

 

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 and (b) in the event that the Securities of
any series then Outstanding are convertible into or exchangeable for shares of common
stock or other securities of the Company, such entity shall, by such
supplemental indenture, make provision so that the Securityholders of
Securities of that series shall thereafter be entitled to receive upon
conversion or exchange of such Securities the number of securities or property
to which a holder of the number of shares of common stock or other securities
of the Company deliverable upon conversion or exchange of those Securities
would have been entitled had such conversion or exchange occurred immediately
prior to such consolidation, merger, sale, conveyance, transfer or other
disposition.

 

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).

SATISFACTION AND DISCHARGE

 

Section 11.01                     Satisfaction and Discharge of
Indenture.

 

If at any time: (a) the
Company shall have delivered to the Trustee for cancellation all Securities of
a series theretofore authenticated and not delivered to the Trustee for
cancellation (other than any Securities that shall have been destroyed, lost or
stolen and that shall have been replaced or paid as provided in Section 2.07
and Securities for whose payment money or Governmental Obligations have
theretofore been deposited in trust or segregated and held in trust by the
Company and thereupon repaid to the Company or discharged from such trust, as
provided in Section 11.05); or (b) all such Securities of a
particular series not theretofore delivered to the Trustee for cancellation
shall have become due and payable, or are by their terms to become due and
payable within one year or are to be called for redemption within one year
under arrangements satisfactory to the Trustee for the giving of notice of
redemption, and the Company shall deposit or cause to be deposited with the
Trustee as trust funds the entire amount in moneys or Governmental Obligations
or a combination thereof, sufficient in the opinion of a nationally recognized
firm of independent public accountants expressed in a written certification
thereof delivered to the Trustee, to pay at maturity or upon redemption all
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 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 acknowledging
satisfaction of and discharging this Indenture with respect to such series.

 

Section 11.02                     Discharge of Obligations.

 

If at any time all such
Securities of a particular series not heretofore delivered to the Trustee for
cancellation or that have not become due and payable as described in Section 11.01
shall have been paid by the Company by depositing irrevocably with the Trustee
as trust funds moneys or an 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 shall mature and be paid.

 

40

 

Thereafter, Sections 7.06
and 11.05 shall survive.

 

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 only to the Company for
the payment thereof.

Except as otherwise
expressly provided herein, any notice, request or demand that by any provision

applicable.

 

Section 13.06                     Treatment of Securities as Debt.

 

It is intended that the

Indenture, the Company shall furnish to the Trustee an Officers’ Certificate

statement as to whether or not, in the opinion of such Person, such condition
or covenant has been complied with.

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, in any case where the date of maturity of interest or
principal of any Security or the date of redemption of any Security shall not
be a Business Day, then payment of interest or principal (and premium, if any)
may be made on the next succeeding Business Day with the same force and effect
as if made on the nominal date of maturity or redemption, and no interest shall
accrue for the period after such nominal date.

 

43

 

Section 13.09                     Conflict with Trust Indenture Act.

Section 13.11                     Separability.

 

In case any one or more
of the provisions contained in this Indenture or in the Securities of any
series shall for any reason be held to be invalid, illegal or unenforceable in
any respect, such invalidity, illegality or unenforceability shall not affect
any other provisions of this Indenture or of such Securities, but this
Indenture and such Securities shall be construed as if such invalid or illegal
or unenforceable provision had never been contained herein or therein.

 

Section 13.12                     Compliance Certificates.

 

The Company shall deliver
to the Trustee, within 120 days after the end of each fiscal year during which
any Securities of any series were outstanding, an officer’s certificate stating
whether or not the signers know of any Default or Event of Default that
occurred during such fiscal year. Such certificate shall contain a
certification from the principal executive officer, principal financial officer
or principal accounting officer of the Company that a review has been conducted
of the activities of the Company and the Company’s performance under this
Indenture and that the Company has complied with all conditions and covenants
under this Indenture. For purposes of this Section 13.12, such compliance
shall be determined without regard to any period of grace or requirement of
notice provided under this Indenture. If the officer of the Company signing
such certificate has knowledge of such a Default or Event of Default, the
certificate shall describe any such Default or Event of Default and its status.

 

44

Indenture to be duly executed all as of the day and year first above written.

All Securities of any one
series shall be substantially identical except as to denomination and except as
may otherwise be provided in or pursuant to any such Board Resolution or in any
indentures supplemental hereto.

 

If any of the terms of
the series are established by action taken pursuant to a Board Resolution of
the Company, a copy of an appropriate record of such action shall be certified
by the secretary or an assistant secretary of the Company and delivered to the
Trustee at or prior to the delivery of the Officers’ Certificate of the Company
setting forth the terms of the series.

 

Securities of any
particular series may be issued at various times, with different dates on which
the principal or any installment of principal is payable, with different rates
of interest, if any, or different methods by which rates of interest may be
determined, with different dates on which such interest may be payable and with
different redemption dates.

 

Section 2.02                            Form of Securities and
Trustee’s Certificate.

 

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

Section 2.03                            Denominations: Provisions for
Payment.

 

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

 

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

 

Any interest on any
Security that is payable, but is not punctually paid or duly provided for, on
any Interest Payment Date for Securities of the same series (herein called “Defaulted
Interest”) shall forthwith cease to be payable to the registered holder on the
relevant regular record date by virtue of having been such holder; and such
Defaulted Interest shall be paid by the Company, at its election, as provided
in clause (1) or clause (2) below:

 

(1)                                 The Company may make payment of any
Defaulted Interest on Securities to the Persons in whose names such Securities
(or their respective Predecessor Securities) are registered at the close of
business on a special record date for the payment of such Defaulted Interest,
which shall be fixed in the following manner: the Company shall notify the
Trustee in writing of the amount of Defaulted Interest proposed to be paid on
each such Security and the date of the proposed payment, and at the same time
the Company shall deposit with the Trustee an amount of money equal to the
aggregate amount proposed to be paid in respect of such 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 

 

8

 

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 Authentications.

 

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.

 

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 

 

9

 

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
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.

 

10

 

(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 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.

 

11

 

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. On
request of the Company at the time of such surrender, the Trustee shall deliver
to the Company canceled Securities held by the Trustee. In the absence of such
request the Trustee may dispose of canceled Securities in accordance with its
standard procedures and deliver a certificate of disposition to the Company. If
the Company shall otherwise acquire any of the Securities, however, such
acquisition shall not operate as a 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).

 

12

 

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, 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.

 

13

 

(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 

 

14

 

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.

 

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 redemption through
operation of the sinking fund and the amount of such sinking fund payment shall
be reduced accordingly.

 

16

 

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.

date). Payments of interest on the Securities may be made at the time provided
herein and established with respect to such Securities by U.S. dollar check

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 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 

 

18

 

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.

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 Collected.

 

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

(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.

 

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.

 

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

 

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 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
exclusively 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, including the
administration of the trust created by this Indenture, shall be the successor
of the Trustee hereunder, provided that such corporation shall be qualified
under the

 

33

 

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, 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

SUPPLEMENTAL INDENTURES

 

Section 9.01                            Supplemental Indentures Without
the Consent of Securityholders.

 

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

 

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

 

(b)                                  to comply with Article Ten;

 

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

 

36

 

(d)                                  to add to the covenants, restrictions,
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,
may receive an Officers’ Certificate or an Opinion of Counsel as conclusive
evidence that any supplemental indenture executed pursuant to this Article is
authorized or permitted by, and conforms to, the terms of this Article and
that it is proper for the Trustee under the provisions of this Article to
join in the execution thereof; provided, however, that such Officers’
Certificate or Opinion of

 

38

 

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.

 

ARTICLE 10

SUCCESSOR ENTITY

 

Section 10.01                     Company May Consolidate,
Etc.

 

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, (a) 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 and (b) in
the event that the Securities of any series then Outstanding are convertible
into or exchangeable for shares of common stock or other securities of the
Company, such entity shall, by such supplemental indenture, make provision so
that the Securityholders of Securities of that series shall thereafter be
entitled to receive upon conversion or exchange of such Securities the number
of securities or property to which a holder of the number of shares of common
stock or other securities of the Company deliverable upon conversion or
exchange of those Securities would have been entitled had such conversion or exchange
occurred immediately prior to such consolidation, merger, sale, conveyance,
transfer or other disposition.

 

39

 

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.

40

 

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

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 shall mature and be paid.

 

Thereafter, Sections 7.06
and 11.05 shall survive.

 

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.

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

No recourse under or upon
any obligation, covenant or agreement of this Indenture, or of any Security, or
for any claim based thereon or otherwise in respect thereof, shall be had

future as such, of the Company or of any predecessor or successor corporation,
either directly or through the Company or any such predecessor or successor
corporation, whether by virtue of any constitution, statute or rule of

are solely corporate obligations, and that no such personal liability whatever
shall attach to, or is or shall be incurred by, the incorporators,
stockholders, officers or directors as such, of the Company or of any
predecessor or successor corporation, or any of them, because of the creation

an Officers’ Certificate, or established in one or more indentures supplemental
to this Indenture, in any case where the date of maturity of interest or
principal of any Security or the date of redemption of any Security shall not

any respect, 

 

44

 

such invalidity,
illegality or unenforceability shall not affect any other provisions of this

or principal accounting officer of the Company that a review has been conducted
of the activities of the Company and the Company’s performance under this
Indenture and that the Company has complied with all conditions and covenants
under this Indenture. For purposes of this Section 13.12, such compliance
shall be determined without regard to any period of grace or requirement of
notice provided under this Indenture. If the officer of the Company signing
