     (14) whether or not the Debentures are to be sold to Persons who are not directly or

for such other currency or currency unit existing on or about the time a payment is due; and

     (16) any and all other terms with respect to such series (which terms shall not be

          All Debentures 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
indenture supplemental hereto.

          If any of the terms of the series are established by action taken pursuant to a Board
Resolution, 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 Officer’s Certificate setting forth the terms of the series.

Resolution and set forth in an Officer’s Certificate, and may have such letters, numbers or other
marks of identification or designation and such legends or endorsements printed, lithographed or
engraved thereon as the Company may deem appropriate and as are not inconsistent with the
provisions of this Indenture, or as may be required to comply with any law or with any rule or
regulation made pursuant thereto or with any rule or regulation of any stock exchange on which
Debentures of that series may be listed, or to conform to usage.

     SECTION 2.03. Date and Denominations of Debentures; Payment of Principal,
Premium and Interest.

          The Debentures shall be issuable as registered Debentures without coupons and in the
denominations of $25 or any integral multiple thereof, subject to Sections 2.01(10) and 2.01(16).
The Debentures of a particular series shall bear interest payable on the dates and at the rate
specified with respect to that series. Unless otherwise provided in a Supplemental Indenture

9

 

or Officer’s Certificate for a series of Debentures, the principal of and the interest on the
Debentures 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 which 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 Place of Payment for that series of Debentures. Each Debenture shall be
dated the date of its authentication. Interest on the Debentures shall be computed on the basis of
a 360-day year composed of twelve 30-day months, except that for any period shorter than a full
90-day quarter, interest will be computed on the basis of the actual number of days elapsed in such
90-day quarter.

          The interest installment on any Debenture which is payable, and is punctually paid or duly
provided for, on any Interest Payment Date for Debentures of that series shall be paid to the
person in whose name said Debenture (or one or more Predecessor Debentures) is registered on the
Debenture Register at the close of business on the regular record date for such interest
installment. In the event that any Debenture 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 Debenture will be
paid upon presentation and surrender of such Debenture as provided in Section 3.03.

          Any interest on any Debenture which is payable, but is not punctually paid or duly provided
for, on any Interest Payment Date for Debentures 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 Debentures to the persons
in whose names such Debentures (or their respective Predecessor Debentures) 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
Debenture 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 Debentureholder at its
address as it appears in the Debenture Register, 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

10

 

names such Debentures (or their Predecessor Debentures) are registered on such special
record date and shall be no longer payable pursuant to the following clause (2).

     (2) The Company may make payment of any Defaulted Interest on any Debentures in any
other lawful manner not inconsistent with the requirements of any securities exchange on
which such Debentures 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 or pursuant to a Board Resolution or one or more indentures
supplemental hereto establishing the terms of any series of Debentures pursuant to Section 2.01
hereof, the term “regular record date” as used in this Section with respect to a series of
Debentures with respect to any Interest Payment Date for such series shall mean either the
fifteenth day of the month immediately preceding the month in which an Interest Payment Date
established for such series pursuant to Section 2.01 hereof shall occur, if such Interest Payment
Date is the first day of a month, or the last day of the month immediately preceding the month in
which an Interest Payment Date established for such series pursuant to Section 2.01 hereof shall
occur, if such Interest Payment Date is the fifteenth day of a month, whether or not such date is a
business day.

          Subject to the foregoing provisions of this Section, each Debenture of a series delivered
under this Indenture upon transfer of or in exchange for or in lieu of any other Debenture of such
series shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by
such other Debenture.

     SECTION 2.04. Execution of Debentures.

          The Debentures shall, subject to the provisions of Section 2.06, be printed on steel engraved
borders or fully or partially engraved, or legibly typed, as the proper officers of the Company may
determine, and shall be signed on behalf of the Company by its President or any Vice President and
by its Treasurer, Controller or Secretary or an Assistant Treasurer or Assistant Secretary, under
its corporate seal or a facsimile thereof reproduced thereon. The signature of any of these
officers on the Debentures may be manual or facsimile. The seal of the Company may be in the form
of a facsimile of the seal of the Company and may be impressed, affixed, imprinted or otherwise
reproduced on the Debentures.

          Debentures bearing the manual or facsimile signatures of individuals who were at any time the
proper officers of the Company shall bind the Company, notwithstanding that such individuals or any
of them have ceased to hold such offices prior to the authentication and delivery of such
Debentures and did not hold such offices at the date of such Debentures.

          Only such Debentures as shall bear thereon a Certificate of Authentication substantially in
the form established for such Debentures, executed manually by an authorized signatory of the
Trustee, or by any Authenticating Agent with respect to such Debentures, shall be entitled to the
benefits of this Indenture or be valid or obligatory for any purpose. Such certificate executed by
the Trustee, or by any Authenticating Agent appointed by the Trustee

11

 

with respect to such Debentures, upon any Debenture executed by the Company shall be
conclusive evidence that the Debenture 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 Debentures 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 Debentures, signed by its President or any Vice President and by its Treasurer, Controller or
Secretary or any Assistant Treasurer or Assistant Secretary, and the Trustee in accordance with
such written order shall authenticate and make available for delivery such Debentures.

          In authenticating such Debentures and accepting the additional responsibilities under this
Indenture in relation to such Debentures, 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 Debentures if the issue of such
Debentures pursuant to this Indenture will affect the Trustee’s own rights, duties or immunities
under the Debentures and this Indenture or otherwise in a manner which is not reasonably acceptable
to the Trustee.

     SECTION 2.05. Mutilated, Destroyed, Lost or Stolen Debentures.

          In case any temporary or definitive Debenture shall become mutilated or be destroyed, lost or
stolen, the Company (subject to the next succeeding sentence) shall execute, and upon its request
the Trustee (subject as aforesaid) shall authenticate and deliver, a new Debenture of the same
series bearing a number not contemporaneously Outstanding, in exchange and substitution for the
mutilated Debenture, or in lieu of and in substitution for the Debenture so destroyed, lost or
stolen. In every case the applicant for a substituted Debenture shall furnish to the Company and
to 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 to the Trustee evidence to their satisfaction of the destruction, loss or theft of the
applicant’s Debenture and of the ownership thereof. The Trustee may authenticate any such
substituted Debenture and deliver the same upon the written request or authorization of any officer
of the Company. Upon the issuance of any substituted Debenture, 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 Debenture which has matured or is about to mature shall become mutilated or
be destroyed, lost or stolen, the Company may, instead of issuing a substitute Debenture, pay or
authorize the payment of the same (without surrender thereof except in the case of a mutilated
Debenture) if the applicant for such payment shall furnish to the Company and to 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 Debenture and of the ownership thereof.

12

 

          Every Debenture issued pursuant to the provisions of this Section in substitution for any
Debenture which is mutilated, destroyed, lost or stolen shall constitute an additional contractual
obligation of the Company, whether or not the mutilated, destroyed, lost or stolen Debenture 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 Debentures of the same series
duly issued hereunder. All Debentures 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 Debentures, 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 2.06. Temporary Debentures.

          Pending the preparation of definitive Debentures of any series, the Company may execute, and
the Trustee shall authenticate and deliver, temporary Debentures (printed, lithographed or
typewritten) of any authorized denomination, and substantially in the form of the definitive
Debentures in lieu of which they are issued, but with such omissions, insertions and variations as
may be appropriate for temporary Debentures, all as may be determined by the Company. very
temporary Debenture 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 Debentures of such series. Without unnecessary delay the Company will execute and will
furnish definitive Debentures of such series and thereupon any or all temporary Debentures 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 a Place of Payment for that series, and the
Trustee shall authenticate and such office or agency shall deliver in exchange for such temporary
Debentures an equal aggregate principal amount of definitive Debentures of such series, unless the
Company advises the Trustee to the effect that definitive Debentures need not be executed and
furnished until further notice from the Company. Until so exchanged, the temporary Debentures of
such series shall be entitled to the same benefits under this Indenture as definitive Debentures of
such series authenticated and delivered hereunder.

     SECTION 2.07. Exchange of Debentures.

          (a) Debentures of any series may be exchanged upon presentation thereof at the office or
agency of the Company in a Place of Payment for that series, for other Debentures 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 Debentures so surrendered for exchange, the Company shall execute,
the Trustee shall authenticate and such office or agency shall deliver in exchange therefor the
Debenture or Debentures of the same series which the Debentureholder making the exchange shall be
entitled to receive, bearing numbers not contemporaneously Outstanding.

          (b) The Company shall keep, or cause to be kept, at the Corporate Trust Office of the Trustee,
or such other location designated by the Company in the Place of Payment,

13

 

a register or registers (the “Debenture Register”) in which, subject to such reasonable
regulations as it may prescribe, the Company shall register the Debentures and the transfers of
Debentures as in this Article provided and which at all reasonable times shall be open for
inspection by the Trustee. Unless otherwise provided by Board Resolution for a series of
Debentures, the Trustee is hereby appointed as the registrar for the purpose of registering
Debentures and transferring Debentures as herein provided (the “Debenture Registrar”).

          Upon surrender for transfer of any Debenture at the Corporate Trust Office of the Trustee or
such other location designated by the Company, the Company shall execute, the Trustee shall
authenticate and such office or agency shall make available for delivery in the name of the
transferee or transferees a new Debenture or Debentures of the same series as the Debenture
presented for a like aggregate principal amount.

          All Debentures 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 Debenture Registrar) by
a written instrument or instruments of transfer, in form satisfactory to the Company or the
Debenture Registrar, duly executed by the registered holder or by its duly authorized attorney in
writing.

          (c) No service charge shall be made for any exchange or registration of transfer of
Debentures, or issue of new Debentures in case of partial redemption of any series, but the Company
or the Trustee 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
Debentures 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 Debentures 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 Debentures of any series or portions thereof called for redemption. The
provisions of this Section 2.07 are, with respect to any Global Debenture, subject to Section 2.11
hereof.

     SECTION 2.08. Cancellation.

          All Debentures surrendered for the purpose of payment, redemption, exchange or registration of
transfer shall, if surrendered to the Company or any paying agent, be delivered to the Trustee for
cancellation, or, if surrendered to the Trustee, shall be canceled by it, and no Debentures 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, the Trustee shall deliver to the Company canceled
Debentures held by the Trustee. In the absence of such request the Trustee may dispose of canceled
Debentures in accordance with its standard procedures and deliver a certificate of disposition to
the Company. If the Company shall otherwise acquire any of the Debentures, however, such
acquisition shall not operate as a redemption or satisfaction of the indebtedness represented by
such Debentures unless and until the same are delivered to the Trustee for cancellation.

     SECTION 2.09. Beneficiaries.

          Nothing in this Indenture or in the Debentures, express or implied, shall give or be construed
to give to any person, firm or corporation, other than the parties hereto and the holders of the
Debentures, 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 Debentures.

     SECTION 2.10. Appointment of Authenticating Agent.

          So long as any of the Debentures of any series remain Outstanding there may be an
Authenticating Agent for any or all such series of Debentures which the Trustee shall have the
right to appoint. Said Authenticating Agent shall be authorized to act on behalf of the Trustee to
authenticate Debentures of such series issued upon exchange, transfer or partial redemption
thereof, and Debentures 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 Debentures by the Trustee shall be deemed to
include authentication by an Authenticating Agent for such series except for authentication upon
original issuance or pursuant to Section 2.05 hereof. Each Authenticating Agent shall be
acceptable to the Company and shall be a corporation which 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 which 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.

          The Company agrees to pay to each Authenticating Agent from time to time reasonable
compensation for its services under this Section.

     SECTION 2.11. Global Debenture.

          (a) If the Company shall establish pursuant to Section 2.01 that the Debentures of a
particular series are to be issued in whole as one or more Global Debentures, then the Company
shall execute and the Trustee shall, in accordance with Section 2.04, authenticate .and deliver,
one or more Global Debentures which (i) shall represent, and shall be denominated in an aggregate
amount equal to the aggregate principal amount of, all of the

15

 

Outstanding Debentures of such series, (ii) shall be registered in the name of the Depository
or its nominee, (iii) shall be delivered by the Trustee to the Depository or pursuant to the
Depository’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 Debenture may be transferred,
in whole but not in part, only to another nominee of the Depository or to a successor Depository or
to a nominee of such successor Depository.”

          (b) Notwithstanding the provisions of Section 2.07, unless and until it is exchanged in whole
or in part for Debentures in definitive registered form, the Global Debenture or Debentures of a
series may be transferred, in whole but not in part and in the manner provided in Section 2.07,
only to another nominee of the Depository for such series, or to a successor Depository for such
series selected or approved by the Company or to a nominee of such successor Depository.

          (c) If at any time the Depository for a series of Debentures notifies the Company that it is
unwilling or unable to continue as Depository for such series or if at any time the Depository 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 Depository for such series is not appointed by the
Company within 90 days after the Company receives such notice or becomes aware of such condition,
as the case may be, this Section 2.11 shall no longer be applicable to the Debentures of such
series and the Company will execute and, subject to Section 2.07, the Trustee will authenticate and
make available for delivery Debentures 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 Debentures of such series in exchange for such Global Debenture. In addition,
the Company may at any time determine that the Debentures of any series shall no longer be
represented by one or more Global Debentures and that the provisions of this Section 2.11 shall no
longer apply to the Debentures of such series. In such event the Company will execute and, subject
to Section 2.07, the Trustee, upon receipt of an Officer’s Certificate evidencing such
determination by the Company, will authenticate and make available for delivery Debentures 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 Debentures of such series in
exchange for such Global Debentures. Upon the exchange of the Global Debentures for such
Debentures in definitive registered form without coupons, in authorized denominations, the Global
Debentures shall be canceled by the Trustee. Such Debentures in definitive registered form issued
in exchange for the Global Debentures pursuant to this Section 2.11(c) shall be registered in such
names and in such authorized denominations as the Depository, pursuant to instructions from its
direct or indirect participants or otherwise, shall instruct the Trustee. The Trustee shall
deliver such Debentures to the Depository for delivery to the persons in whose names such
Debentures are so registered.

     SECTION 2.12. CUSIP Numbers.

          The Company in issuing the Debentures may use “CUSIP” numbers (if then generally in use), and,
if so, the Trustee shall use CUSIP numbers in notices of redemption as a convenience to
Debentureholders; provided that any such notice may state that no representation is made as
to the correctness of such numbers either as printed on the Debentures or as contained

16

 

in any notice of a redemption and that reliance may be placed only on the other identification
numbers printed on the Debentures, and any such redemption shall not be affected by any defect in
or omission of such numbers. The Company will promptly notify the Trustee of any change in the
CUSIP numbers.

ARTICLE THREE

Redemption of Debentures and

Sinking Fund Provisions

     SECTION 3.01. Redemption of Debentures.

          The Company may redeem the Debentures 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; Selection by Trustee of Debentures to be
Redeemed.

          (a) In case the Company shall desire to exercise such right to redeem all or, as the case may
be, a portion of the Debentures of any series in accordance with the right reserved so to do, it
shall give notice of such redemption to holders of the Debentures 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 60 days before the date fixed for redemption of that series to such holders at their last
addresses as they shall appear upon the Debenture Register. Any notice which 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 Debenture 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 Debentures
of such series or any other series. In the case of any redemption of Debentures prior to the
expiration of any restriction on such redemption provided in the terms of such Debentures or
elsewhere in this Indenture, the Company shall furnish the Trustee with an Officer’s Certificate
evidencing compliance with any such restriction.

          Each such notice of redemption shall identify the Debentures to be redeemed (including CUSIP
numbers) and shall specify the date fixed for redemption and the redemption price at which
Debentures of that series are to be redeemed, and shall state the place or places where such
Debentures are to be presented and surrendered for payment of the redemption price of such
Debentures to be redeemed, 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 Debentures of a series
are to be redeemed, the notice to the holders of Debentures of that series to be redeemed in whole
or in part shall specify the particular Debentures to be so redeemed. In case any Debenture is to
be redeemed in part only, the notice which relates to such Debenture 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 Debenture, a new Debenture or Debentures of such series in principal amount
equal to the unredeemed portion thereof will be issued.

17

 

          With respect to any notice of redemption of Debentures of any series to be redeemed at the
option of the Company, such notice may state that such redemption shall be conditional upon the
receipt by the Trustee, on or prior to the date fixed for such redemption, of money sufficient to
pay the principal of and premium, if any, and interest, if any, on such Debentures and that if such
money shall not have been so received such notice shall be of no force or effect and the Company
shall not be required to redeem such Debentures. In the event that such notice of redemption
contains such a condition and such money is not so received, the redemption shall not be made and
within a reasonable time thereafter notice shall be given, in the manner in which the notice of
redemption was given, that such money was not so received and such redemption was not required to
be made.

          (b) If the Debentures of a series are to be redeemed, the Company shall give the Trustee at
least 45 days’ notice in advance of the date fixed for redemption as to the aggregate principal
amount of Debentures 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 which may
provide for the selection of a portion or portions (equal to $25 or any integral multiple thereof)
of the principal amount of such Debentures of a denomination larger than $25, the Debentures to be
redeemed and shall thereafter promptly notify the Company in writing of the numbers of the
Debentures to be redeemed, in whole or in part.

          The Company may, if and whenever it shall so elect, by delivery of instructions signed on its
behalf by its President, any Vice President or its Treasurer, Controller or Secretary, instruct the
Trustee or any paying agent to call all or any part of the Debentures 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 Debenture 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. Debentures Payable on Redemption Date; Debentures Redeemed in
Part.

          (a) If the giving of notice of redemption shall have been completed as above provided, the
Debentures or portions of Debentures 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 Debentures or portions of Debentures 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 Debenture or portion thereof. On presentation and surrender of
such Debentures on or after the date fixed for redemption at the place of payment specified in the
notice, said Debentures 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

18

 

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 Debenture of such series which is to be redeemed in part only,
the Company shall execute and the Trustee shall authenticate and the office or agency where the
Debenture is presented shall deliver to the holder thereof, at the expense of the Company, a new
Debenture or Debentures of the same series, of authorized denominations in principal amount equal
to the unredeemed portion of the Debenture so presented.

     SECTION 3.04. Sinking Fund for Debentures.

          The provisions of Sections 3.04, 3.05 and 3.06 shall be applicable to any sinking fund for the
retirement of Debentures of a series, except as otherwise specified in or pursuant to a Board
Resolution or supplemental indenture as contemplated by Section 2.01 for Debentures of such series.

          The minimum amount of any sinking fund payment provided for by the terms of Debentures 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 Debentures of any series is herein referred to as
an “optional sinking fund payment”. If provided for by the terms of Debentures for 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 Debentures of any series as
provided for by the terms of Debentures of such series.

     SECTION 3.05. Satisfaction of Sinking Fund Payments With Debentures.

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

          Not less than 45 days prior to each sinking fund payment date for any series of Debentures,
the Company will deliver to the Trustee an Officer’s Certificate specifying the amount of the next
ensuing sinking fund payment for that series pursuant to the terms for that series, the portion
thereof, if any, which is to be satisfied by delivering and crediting Debentures of that series
pursuant to Section 3.05 and the basis for such credit and will, together with such Officer’s
Certificate, deliver to the Trustee any Debentures to be so delivered. Not less than 30

19

 

days before each such sinking fund payment date the Trustee shall select the Debentures 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
Debentures shall be made upon the terms and in the manner stated in Section 3.03.

ARTICLE FOUR

Particular Covenants of the Company

          The Company covenants and agrees for each series of the Debentures as follows:

     SECTION 4.01. Payment of Principal, Premium and Interest.

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

     SECTION 4.02. Maintenance of Office or Agency.

          So long as any series of the Debentures remain Outstanding, the Company agrees to maintain an
office or agency in the Place of Payment 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) Debentures
of that series may be presented for payment, (ii) Debentures of that series may be presented as
hereinabove authorized for registration of transfer and exchange, and (iii) notices and demands to
or upon the Company in respect of the Debentures of that series and this Indenture may be given or
served, such designation to continue with respect to such office or agency until the Company shall,
by written notice signed by its President, any Vice President or its Treasurer, Controller or
Secretary and delivered to the Trustee, designate some other office or agency for such purposes or
any of them. So long as any series of the Debentures remain Outstanding, such presentations,
notices and demands may also 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. Notwithstanding anything else contained in this Indenture, payment of interest, if any,
on Debentures that are not registered to a Hawaiian Electric Industries Capital Trust may be made
at the option of the Company by check mailed to the address of the Person entitled thereto as it
appears on the Debenture Register or by wire transfer to an account appropriately designated by the
Person entitled thereto as it appears on the Debenture Register.

	 	 	SECTION 4.03. Paying Agent; Money for Debenture Payments to be Held in
Trust.

          (a) If the Company shall appoint one or more paying agents for all or any series of the
Debentures, other than the Trustee, the Company will cause each such paying agency 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:

20

 

     (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 Debentures of that series (whether
such sums have been paid to it by the Company or by any other obligor of such Debentures) 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 Debentures) to make any payment of the principal of (and premium, if any) or
interest on the Debentures 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
subsection (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
Debentures, it will on or before each due date of the principal of (and premium, if any) or
interest on Debentures 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 Debentures 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 Debentures) to take such action. Whenever the
Company shall have one or more paying agents for any series of Debentures, it will, prior to each
due date of the principal of (and premium, if any) or interest on any Debentures 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 its action or failure so to act.

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

     SECTION 4.04. Appointment to Fill Vacancy.

          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.

21

 

     SECTION 4.05. Payment of Additional Interest.

          If, at any time while the Property Trustee is a Debentureholder of any Debentures issued to a
Hawaiian Electric Industries Capital Trust, the Property Trustee shall be required to pay any
taxes, duties, assessments or governmental charges of whatever nature (other than withholding taxes
or taxes or charges imposed by reason of the transfer of the Trust Preferred Securities or
beneficial interests therein) imposed by the United States, or any other taxing authority, then, in
any such case, the Company shall promptly pay, as additional interest (the “Additional Interest”)
on the Debentures held by the Property Trustee, such additional amounts as shall be required so
that the net amounts received and retained by such Trust and the Property Trustee, after paying any
such taxes, duties, assessments or other governmental charges will be equal to the amounts such
Trust and the Property Trustee would have received had no such taxes, duties, assessments or other
governmental charges been imposed.

     SECTION 4.06. Maintenance of the Hawaiian Electric Industries Capital Trust.

          In the event any Debentures are issued to a Hawaiian Electric Industries Capital Trust, or a
Trustee of such a Trust, in connection with the issuance of Trust Preferred Securities of a
Hawaiian Electric Industries Capital Trust, for so long as such Trust Preferred Securities remain
Outstanding, the Company will covenant (i) to directly or indirectly maintain 100 percent ownership
of the Trust Common Securities of such Trust; provided, however, that any permitted successor of
the Company under this Indenture may succeed to the Company’s ownership of such Trust Common
Securities, (ii) to use its reasonable efforts to cause such Trust (a) to remain a statutory
business trust, except in connection with the distribution of the Debentures to the holders of
Trust Preferred Securities and Trust Common Securities in liquidation of such Trust, the redemption
of all of the Trust Preferred Securities and Trust Common Securities of such Trust, or the mergers,
consolidations or amalgamations, each as permitted by the Trust Agreement of such Trust, and (b) to
otherwise continue not to be treated as an association taxable as a corporation or a partnership
for United States federal income tax purposes, and (iii) to use its reasonable efforts to cause
each holder of Trust Common Securities and Trust Preferred Securities to be treated as owning an
undivided beneficial interest in the Debentures.

ARTICLE FIVE

Debentureholders’ Lists and

Reports by the Company and the Trustee

	 	 	SECTION 5.01. Company to Furnish Trustee Names and Addresses of
Debentureholders.

          The Company shall furnish or cause to be furnished to the Trustee (a) on each regular record
date (as defined in Section 2.03), a list in such form as the Trustee may reasonably require, of
the names and addresses of the holders of each series of Debentures as of such regular record date,
provided, that the Company shall not be obligated to furnish or cause to furnish such list at any
time that the list shall not differ in any respect from the most recent list furnished to the
Trustee by the Company and (b) at such other times as the Trustee may request in writing

22

 

within 30 days after the receipt by the Company of any such request, a list of similar form
and content as of a date not more than 15 days prior to the time such list is furnished; provided,
however, no such list need be furnished for any series for which the Trustee shall be the Debenture
Registrar.

     SECTION 5.02. Preservation of Information; Communications to Holders.

          (a) The Trustee shall preserve, in as current a form as is reasonably practicable, all
information as to the names and addresses of the holders of Debentures contained in the most recent
list furnished to it as provided in Section 5.01 and as to the names and addresses of holders of
Debentures received by the Trustee in its capacity as Debenture Registrar (if acting in such
capacity).

          (b) The Trustee may destroy any list furnished to it as provided in Section 5.01 upon receipt
of a new list so furnished.

          (c) In case three or more holders of Debentures of a series (hereinafter referred to as
“applicants”) apply in writing to the Trustee, and furnish to the Trustee reasonable proof that
each such applicant has owned a Debenture for a period of at least six months preceding the date of
such application, and such application states that the applicants desire to communicate with other
holders of Debentures of such series or holders of all Debentures with respect to their rights
under this Indenture or under such Debentures, and is accompanied by a copy of the form of proxy or
other communication which such applicants propose to transmit, then the Trustee shall within five
business days after the receipt of such application, at its election, either:

     (1) afford to such applicants access to the information preserved at the time by the
Trustee in accordance with the provisions of subsection (a) of this Section 5.02; or

     (2) inform such applicants as to the approximate number of holders of Debentures of
such series or of all Debentures, as the case may be, whose names and addresses appear in
the information preserved at the time by the Trustee, in accordance with the provisions of
subsection (a) of this Section 5.02, and as to the approximate cost of mailing to such
Debentureholders the form of proxy or other communication, if any, specified in such
application.

          (d) If the Trustee shall elect not to afford such applicants access to such information, the
Trustee, shall, upon the written request of such applicants, mail to each holder of such series or
of all Debentures, as the case may be, whose name and address appears in the information preserved
at the time by the Trustee in accordance with the provisions of subsection (a) of this Section
5.02, a copy of the form of proxy or other communication which is specified in such request, with
reasonable promptness after a tender to the Trustee of the material to be mailed and of payment, or
provision for the payment, of the reasonable expenses of mailing, unless within five days after
such tender, the Trustee shall mail to such applicants and file with the Securities and Exchange
Commission (the “Commission”), together with a copy of the material to be mailed, a written
statement to the effect that, in the opinion of the Trustee, such mailing would be contrary to the
best interests of the holders of Debentures of such series or of

23

 

all Debentures, as the case may be, or would be in violation of applicable law. Such written
statement shall specify the basis of such opinion. If the Commission, after opportunity for a
hearing upon the objections specified in the written statement so filed, shall enter an order
refusing to sustain any of such objections or if, after the entry of an order sustaining one or
more of such objections, the Commission shall find, after notice and opportunity for hearing, that
all the objections so sustained have been met and shall enter an order so declaring, the Trustee
shall mail copies of such material to all such Debentureholders with reasonable promptness after
the entry of such order and the renewal of such tender; otherwise, the Trustee shall be relieved of
any obligation or duty to such applicants respecting their application.

          (e) Each and every holder of the Debentures, by receiving and holding the same, agrees with
the Company and the Trustee that neither the Company nor the Trustee nor any paying agent nor any
Debenture Registrar shall be held accountable by reason of the disclosure of any such information
as to the names and addresses of the holders of Debentures in accordance with the provisions of
subsection (b) of this Section, regardless of the source from which such information was derived,
and that the Trustee shall not be held accountable by reason of mailing any material pursuant to a
request made under said subsection (b).

     SECTION 5.03. Reports by Company.

          (a) The Company covenants and agrees to file with the Trustee, within 15 days after the
Company is required to file the same with the Commission, copies of the annual reports and of the
information, documents and other reports (or copies of such portions of any of the foregoing as the
Commission may from time to time by rules and regulations prescribe) which the Company may be
required to file with the Commission pursuant to Section 13 or Section 15(d) of the Exchange Act;
or, if the Company is not required to file information, documents or reports pursuant to either of
such sections, then to file with the Trustee and the Commission in accordance with the rules and
regulations prescribed from time to time by the Commission, such of the supplementary and periodic
information, documents and reports which may be required pursuant to Section 13 of the Exchange
Act, in respect of a security listed and registered on a national securities exchange as may be
prescribed from time to time in such rules and regulations.

          (b) The Company covenants and agrees to file with the Trustee and the Commission, in
accordance with the rules and regulations prescribed from time to time by the Commission, such
additional information, documents and reports with respect to compliance by the Company with the

Trustee is entitled to rely exclusively on Officer’s Certificates).

          (d) The Company covenants and agrees to transmit by mail, first class postage prepaid, or

may from time to time agree upon, a Certificate as to the signing officer’s best knowledge of the
Company’s compliance with the conditions and covenants under this Indenture requiring compliance by
the Company. For purposes of this subsection (e), such compliance shall be determined without

the Trustee shall transmit by mail, first class postage prepaid, to the Debentureholders, as their
names and addresses appear upon the Debenture Register, a brief report with respect to any of the
following events which may have occurred within the previous twelve months (but if no such event

and

     (8) any action taken by the Trustee in the performance of its duties under this

notice of which has been or is to be withheld by it in accordance with the provisions of
Section 6.07.

          (b) The Trustee shall transmit by mail, first class postage prepaid, to the Debentureholders,

listed (if so listed) and also with the Commission. The Company agrees to promptly notify the
Trustee when any Debentures become listed on any stock exchange.

ARTICLE SIX

Remedies of the Trustee and Debentureholders

on Event of Default

     SECTION 6.01. Events of Default.

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

     (1) default in the payment of any installment of interest, including any Additional
Interest in respect thereon, upon any of the Debentures of that series, as and when the same
shall become due and payable, and continuance of such default for a period of 30 days;
provided, however, that a valid extension of an interest payment period by the Company shall
not constitute a default in the payment of interest for this purpose;

26

 

     (2) default in the payment of the principal of (or premium, if any, on) any of the
Debentures of that series as and when the same shall become due and payable whether at
maturity, upon redemption, by declaration or otherwise; provided, however, that a valid
extension of the maturity of such Debentures shall not constitute a default for that
purpose;

     (3) default in the performance by the Company of any other of the covenants or
agreements on the part of the Company with respect to that series contained in such
Debentures or otherwise established with respect to that series of Debentures pursuant to
Section 2.01 hereof or contained in this Indenture (other than a covenant or agreement which
has been expressly included in this Indenture solely for the benefit of one or more series
of Debentures other than such series), and the continuance of such default for a period of
90 days after the date on which written notice of such default, 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 aggregate principal amount of the Debentures
of that series at the time Outstanding, unless the Trustee or the holders of not less than
the aggregate principal amount of such series, the holders of which gave such notice, as the
case may be, agree in writing to an extension of such period prior to its expiration;

     (4) a decree or order by a court having jurisdiction in the premises shall have been
entered adjudging the Company as bankrupt or insolvent, or approving as properly filed a
petition seeking liquidation or reorganization of the Company under the Federal Bankruptcy
Code or any other similar applicable Federal or State law, and such decree or order shall
have continued unvacated and unstayed for a period of 90 days; or an involuntary case shall
be commenced under such Code in respect of the Company and shall continue undismissed for a
period of 90 days or an order for relief in such case shall have been entered; or a decree
or order of a court having jurisdiction in the premises shall have been entered for the
appointment on the ground of insolvency or bankruptcy of a receiver or custodian or
liquidator or trustee or assignee in bankruptcy or insolvency of the Company or of its
property, or for the winding up or liquidation of its affairs, and such decree or order
shall have remained in force unvacated and unstayed for a period of 90 days; or

     (5) the Company shall institute proceedings to be adjudicated a voluntary bankrupt, or
shall consent to the filing of a bankruptcy proceeding against it, or shall file a petition
or answer or consent seeking liquidation or reorganization under the Federal Bankruptcy Code
or any other similar applicable Federal or State law, or shall consent to the filing of any
such petition, or shall consent to the appointment on the ground of insolvency or bankruptcy
of a receiver or custodian or liquidator or trustee or assignee in bankruptcy or insolvency
of it or of its property, or shall make an assignment for the benefit of creditors.

          (b) If an Event of Default with respect to the Debentures of any series at the time
Outstanding occurs and is continuing, then, unless the principal of all the Debentures of that
series shall have already become due and payable, either the Trustee or the holders of not less

27

 

than 25% in aggregate principal amount of the Debentures of that series then Outstanding
hereunder, by notice in writing to the Company (and to the Trustee if given by such
Debentureholders), may declare the principal of all the Debentures 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, anything contained in this Indenture or in the Debentures of that series or
established with respect to that series pursuant to Section 2.01 hereof to the contrary
notwithstanding except for subsection (c) of this Section.

          (c) Section 6.01(b), however, is subject to the condition that if, at any time after the
principal of the Debentures 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 Company shall pay or shall deposit with the Trustee a sum sufficient to
pay all matured installments of interest upon all the Debentures of that series and the principal
of (and premium, if any, on) any and all Debentures of that series which 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 Debentures of that series to the date of such
payment or deposit) and the amount payable to the Trustee under Section 7.06, and any and all
Defaults under the Indenture, other than the nonpayment of principal on Debentures of that series
which shall not have become due by their terms, shall have been remedied or waived as provided in
Section 6.06, then and in every such case the holders of a majority in aggregate principal amount
of the Debentures of that series then Outstanding, by written notice to the Company and to the
Trustee, may rescind and annul such declaration and its consequences with respect to that series of
Debentures; but no such rescission and annulment shall extend to or shall affect any subsequent
Default, or shall impair any right consequent thereon.

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

          (e) In the case of any series of Debentures held as trust assets of a Hawaiian Electric
Industries Capital Trust prior to a Security Exchange with respect to the Debentures of that
series, if an Event of Default with respect to the Debentures of such series shall have occurred,
the Company expressly acknowledges that under the circumstances set forth in the applicable Trust
Agreement, any holder of Trust Preferred Securities of the applicable Hawaiian Electric Industries
Capital Trust may enforce directly against the Company the applicable Property Trustee’s rights
hereunder, as the case may be. In furtherance of the foregoing and for the avoidance of any doubt,
the Company acknowledges that, under the circumstances described in the applicable Trust Agreement,
any such holder of Trust Preferred Securities, in its own name, in the name of the applicable
Hawaiian Electric Industries Capital Trust or in the name of the holders of the Trust Preferred
Securities issued by such Hawaiian Electric Industries Capital Trust, may institute or cause to be
instituted a proceeding, including, without limitation, any suit in equity, an action at law or
other judicial or administrative proceeding, to enforce the

28

 

applicable Property Trustee’s rights hereunder directly against the Company as issuer of the
applicable series of Debentures, and may prosecute such proceeding to judgment or final decree, and
enforce the same against the Company.

	 	 	SECTION 6.02. Collection of Indebtedness and Suits for Enforcement by
Trustee.

          (a) The Company covenants that (1) in case Default shall be made in the payment of any
installment of interest on any of the Debentures of a series, or any payment required by any
sinking or analogous fund established with respect to that series as and when the same shall have
become due and payable, and such Default shall have continued for a period of 30 days, or (2) in
case Default shall be made in the payment of the principal of (or premium, if any, on) any of the
Debentures of a series when the same shall have become due and payable, whether upon maturity of
the Debentures 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
Debentures of that series, the whole amount that then shall have become due and payable on all such
Debentures 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 and without duplication of any other amounts paid by
the Company or the applicable Hawaiian Electric Industries Capital Trust in respect thereof) upon
overdue installments of interest at the rate per annum expressed in the Debentures 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) In case the Company shall fail forthwith to pay such amounts upon such demand, the
Trustee, in its own name and as trustee of an express trust, shall be entitled and empowered to
institute any action or proceedings at law or in equity for the collection of the sums so due and
unpaid, and may prosecute any such action or proceeding to judgment or final decree, and may
enforce any such judgment or final decree against the Company or other obligor upon the Debentures
of that series and collect in the manner provided by law out of the property of the Company or
other obligor upon the Debentures of that series wherever situated the moneys adjudged or decreed
to be payable.

          (c) In case of any receivership, insolvency, liquidation, bankruptcy, reorganization,
readjustment, arrangement, composition or other judicial proceedings affecting the Company, any
other obligor on such Debentures, or the creditors or property of either, the Trustee shall have
the 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 Debentures of such series allowed for the entire amount due
and payable by the Company or such other obligor under the Indenture at the date of institution of
such proceedings and for any additional amount which may become due and payable by the Company or
such other obligor 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

29

 

holders of Debentures 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 Debentureholders, 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 Debentures of that series, may be enforced by the Trustee without
the possession of any of such Debentures, 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 Debentures 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 herein contained shall be deemed to authorize the Trustee to authorize or consent to
or accept or adopt on behalf of any Debentureholder any plan of reorganization, arrangement,
adjustment or composition affecting the Debentures of that series or the rights of any holder
thereof or to authorize the Trustee to vote in respect of the claim of any Debentureholder in any
such proceeding.

     SECTION 6.03. Application of Moneys Collected.

          Any moneys collected by the Trustee pursuant to Section 6.02 with respect to a particular
series of Debentures shall be applied in the order following, 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 several Debentures of that series, and stamping thereon
the payment, if only partially paid, and upon surrender thereof if fully paid:

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

          SECOND: To the payment of the amounts then due and unpaid upon Debentures 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 Debentures for principal (and premium, if any) and interest,
respectively.

	 	 	SECTION 6.04. Limitation on Suits; Unconditional Right of Debentureholders to
Institute Certain Suits.

          No holder of any Debenture 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

30

 

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

          (a) such holder previously shall have given to the Trustee written notice of an Event of
Default and of the continuance thereof with respect to Debentures of such series specifying such
Event of Default, as hereinbefore provided;

          (b) the holders of not less than 25% in aggregate principal amount of the Debentures 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;

          (c) such holder or holders have offered to the Trustee such reasonable indemnity as it may
require against the costs, expenses and liabilities to be incurred therein or thereby;

          (d) the Trustee for 60 days after its receipt of such notice, request and offer of indemnity,
shall have failed to institute any such action, suit or proceeding; and

          (e) no direction inconsistent with such written request has been given to the Trustee during
such 60-day period by the holders of a majority in principal amount of the Outstanding Debentures
of that series;

it being understood and intended, and being expressly covenanted by the taker and holder of every
Debenture of such series with every other such taker and holder and Trustee, that no one or more
holders of Debentures 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 Debentures, 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 Debentures of such series.
For the protection and enforcement of the provisions of this Section, each and every
Debentureholder and the Trustee shall be entitled to such relief as can be given either at law or
in equity.

          Notwithstanding any other provisions of this Indenture, however, the right of any holder of
any Debenture to receive payment of the principal of (and premium, if any) and interest on such
Debenture, as therein provided, on or after the respective due dates expressed in such Debenture
(or in the case of redemption, on the redemption date) as the same may be extended, 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.

	 	 	SECTION 6.05. Rights and Remedies Cumulative; Delay or Omission Not A
Waiver.

          (a) All powers and remedies given by this Article to the Trustee or to the Debentureholders
shall, to the extent permitted by law, be deemed cumulative and not exclusive of any others thereof
or of any other powers and remedies available to the Trustee or the holders of the Debentures, by
judicial proceedings or otherwise, to enforce performance or observance of

31

 

the covenants and agreements contained in this Indenture or otherwise established with respect
to such Debentures.

          (b) No delay or omission of the Trustee or of any holder of any of the Debentures 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 to the Debentureholders may be exercised from time to
time, and as often as shall be deemed expedient, by the Trustee or by the Debentureholders.

     SECTION 6.06. Control by Debentureholders; Waiver of Past Defaults.

          The holders of a majority in aggregate principal amount of the Debentures of any series at the
time Outstanding, determined in accordance with Article Eight, 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 that
(1) such direction shall not be in conflict with any rule of law or with this Indenture or unduly
prejudicial to the rights of holders of Debentures of any other series at the time Outstanding
determined in accordance with Article Eight, and (2) the Trustee may take any other action deemed
proper by the Trustee which is not inconsistent with such direction. Subject to the provisions of
Section 7.01, the Trustee shall have the right to decline to follow any such direction if the
Trustee in good faith shall, by a Responsible Officer or Officers of the Trustee, determine that
the proceeding so directed would involve the Trustee in personal liability. The holders of a
majority in aggregate principal amount of the Debentures of any series at the time Outstanding
affected thereby, determined in accordance with Article Eight, may on behalf of the holders of all
of the Debentures 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 Debentures of that series as and when the same shall become due by the terms of such
Debentures 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)) or a call for redemption of Debentures of that
series. 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 Debentures 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. Notice of Defaults.

          The Trustee shall, within 90 days after the occurrence of an Event of Default with respect to
a particular series, transmit by mail, first class postage prepaid, to the holders of Debentures of
that series, as their names and addresses appear upon the Debenture Register, notice of all
Defaults with respect to that series known to the Trustee, unless such Defaults shall have been
cured before the giving of such notice (Defaults in this context shall not include any periods of
grace provided for therein and shall be irrespective of the giving of notice provided for

32

 

by subsection (3) of Section 6.01(a)); provided, that, except in the case of Default in the
payment of the principal of (or premium, if any) or interest on any of the Debentures of that
series or in the payment of any sinking fund installment established with respect to that series,
the Trustee shall be protected in withholding such notice if and so long as the board of directors,
the executive committee, or a trust committee of directors and/or Responsible Officers, of the
Trustee in good faith determine that the withholding of such notice is in the interests of the
holders of Debentures of that series; provided further, that in the case of any Default of the
character specified in Section 6.01(a)(3) with respect to Debentures of such series no such notice
to the holders of the Debentures of that series shall be given until at least 30 days after the
occurrence thereof.

          The
Trustee shall not be deemed to have knowledge of any Event of Default
or Default, except (i) an Event of Default under
subsection (a)(1) or (a)(2) of Section 6.01 as long as the Trustee is acting as paying agent for
such series of Debentures or (ii) any Default as to which the Trustee shall have received written
notice or a Responsible Officer charged with the administration of this Indenture shall have
obtained written notice.

     SECTION 6.08. Undertaking for Costs.

          All parties to this Indenture agree, and each holder of any Debentures by its 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 and expenses, against any party litigant in
such suit, having due regard to the merits and good faith of the claims or defenses made by such
party litigant; but the provisions of this Section shall not apply to any suit instituted by the
Trustee, to any suit instituted by any Debentureholder, or group of Debentureholders, holding more
than 10% in aggregate principal amount of the Outstanding Debentures of any series, or to any suit
instituted by any Debentureholder for the enforcement of the payment of the principal of (or
premium, if any) or interest on any Debenture of such series, on or after the respective due dates
expressed in such Debenture or established pursuant to this Indenture.

     SECTION 6.09. Certain Additional Covenants.

          If (i) there shall have occurred any Event of Default relating to any series of Debentures,
(ii) the Company shall be in Default with respect to its payments of any obligations under a
related Trust Guarantee, or (iii) the Company shall have given notice of its election to defer
payments of interest on any series of Debentures by extending the interest payment period as
provided in and permitted by a supplemental indenture to this Indenture or in or pursuant to a
Board Resolution, and such period, or any extension thereof, shall be continuing, then (a) the
Company shall not declare or pay any dividend on, make any distributions with respect to, or
redeem, purchase, acquire or make a liquidation payment with respect to, any of its capital stock
(except for dividends or distributions in shares of, or options, warrants or rights to subscribe
for or purchase shares of, its common stock and other than (x) purchases or acquisitions of shares
of the Company’s common stock in connection with the satisfaction by the Company of its

33

 

obligations under any employee benefit, dividend reinvestment, stock purchase or other stock
plans or any other contractual obligation of the Company (other than a contractual obligation
ranking pari passu with or junior to the Debentures), (y) as a result of a reclassification of the
Company’s capital stock or the exchange or conversion of one class or series of the Company’s
capital stock for another class or series of the Company’s capital stock, or (z) the purchase of
fractional interests in shares of the Company’s capital stock pursuant to the conversion or
exchange provisions of such capital stock of the Company or the security being converted or
exchanged), (b) the Company shall not make any payment of interest, principal or premium, if any,
on or repay, repurchase or redeem any debt securities issued by the Company which rank pari passu
with or junior to such Debentures, provided that, if only the event referred to in clause (iii)
above (and not the events referred to in clause (i) or (ii)) has occurred, this restriction shall
apply only to other series of Debentures or debt securities with equivalent deferral options, and
(c) the Company shall not make any guarantee payments with respect to the foregoing (other than
pursuant to the Trust Guarantee, or any other guarantee by the Company with respect to comparable
securities).

ARTICLE SEVEN

Concerning the Trustee

     SECTION 7.01. Certain Duties and Responsibilities.

          (a) Except during the continuance of an Event of Default, the Trustee undertakes to perform
with respect to Debentures 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 Debentures of a series has occurred (which
has not been cured or waived), the Trustee shall exercise with respect to Debentures of that series
such rights and powers vested in it by this Indenture, and use the same degree of care and skill in
their exercise, as a prudent person, would exercise or use under the circumstances in the conduct
of its own affairs.

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

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

     (i) the duties and obligations of the Trustee shall with respect to Debentures
of such series be determined solely by the express provisions of this Indenture, and
the Trustee shall not be liable with respect to Debentures 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

34

 

     (ii) in the absence of bad faith on the part of the Trustee, the Trustee may
with respect to Debentures 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 which by any
provision hereof are specifically required to be furnished to the Trustee, the
Trustee shall be under a duty to examine the same to determine whether or not they
conform to the requirements of this Indenture;

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

     (3) the Trustee shall not be liable with respect to any action taken or omitted to be
taken by it in good faith in accordance with the direction of the holders of not less than a
majority in principal amount of the Debentures 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 Debentures of that series; and

     (4) none of the provisions contained in this Indenture shall require the Trustee to
expend or risk its own funds or otherwise incur personal financial liability in the
performance of any of its duties or in the exercise of any of its rights or powers, if there
is reasonable ground for believing that the repayment of such funds or liability is not
reasonably assured to it under the terms of this Indenture or adequate indemnity against
such risk is not reasonably assured to it.

     SECTION 7.02. Certain Rights of Trustee.

          Except as otherwise provided in Section 7.01:

          (a) The Trustee may rely and shall be protected in acting or refraining from acting upon any
resolution, certificate, statement, instrument, opinion, report, notice, request, consent, order,
approval, bond, security or other paper or document believed by it to be the 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
its President, any Vice President or its Treasurer, Controller or Secretary (unless other evidence
in respect thereof is specifically prescribed herein);

          (c) The Trustee may consult with counsel of its selection and the 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

35

 

Debentureholders, pursuant to the provisions of this Indenture, unless such Debentureholders
shall have offered to the Trustee reasonable security or indemnity against the costs, expenses and
liabilities which may be incurred therein or thereby;

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

          (g) The Trustee 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; and

          (h) The Trustee shall not be deemed to have notice of any Event of Default unless a
Responsible Officer of the Trustee charged with the administration of
this Indenture has actual knowledge thereof or unless written notice of any
event which is in fact such a Default is received by a Responsible
Officer of the Trustee (who is charged with administration of this
Indenture) at the Corporate Trust Office of
the Trustee, and such notice references the Debentures and this Indenture.

     SECTION 7.03. Limitations of Liability.

          (a) The recitals contained herein and in the Debentures (other than the Certificate of
Authentication on the Debentures) 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 Debentures.

          (c) The Trustee shall not be accountable for the use or application by the Company of any of
the Debentures or of the proceeds of such Debentures, 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.

36

 

     SECTION 7.04. Ownership of Debentures.

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

     SECTION 7.05. Moneys Held Without Interest.

          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 in writing with the Company to pay thereon.

     SECTION 7.06. Compensation and Reimbursement.

          (a) The Company covenants and agrees to pay to the Trustee from time to time, and the Trustee
shall be entitled to, such compensation as the Company and the Trustee shall from time to time
agree (which shall not be limited by any provision of law in regard to the compensation of a
trustee of an express trust) 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 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. 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, damage, claim or expense, including taxes (other
than taxes based on the income of the Trustee) incurred without negligence or bad faith on the part
of the Trustee and arising out of or in connection with the acceptance or administration of this
trust, including the costs and expenses 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 expenses, disbursements and advances shall constitute
additional indebtedness hereunder. Such additional indebtedness shall be secured by a lien prior
to that of the Debentures 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 Debentures.

          When the Trustee incurs expenses or renders services in connection with an Event of Default
specified in Section 6.01(a)(4) or Section 6.01(a)(5), the expenses (including the reasonable
charges and expenses of its counsel) and the compensation for the services are intended to
constitute expenses of administration under any applicable Federal or State bankruptcy, insolvency
or other similar law.

          The provisions of this Section shall survive the termination of this Indenture.

37

 

     SECTION 7.07. Reliance on Certificate of Officers of Company.

          Except as otherwise provided in Section 7.01, whenever in the administration of the provisions
of this Indenture the Trustee shall deem it necessary or desirable that a matter be proved or
established prior to taking or suffering or omitting to take any action hereunder, such matter
(unless other evidence in respect thereof be herein specifically prescribed) may, in the absence of
negligence or bad faith on the part of the Trustee, be deemed to be conclusively proved and
established by an Officer’s 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. Conflicts of Interest.

          (a) If the Trustee has or shall acquire any conflicting interest, as defined in this Section,
with respect to the Debentures of any series, it shall, within 90 days after ascertaining that it
has such conflicting interest, either eliminate such conflicting interest or, except as otherwise
provided in this Section 7.08, resign with respect to the Debentures of that series in the manner
and with the effect specified in Section 7.10 and the Company shall promptly appoint a successor
Trustee in the manner provided herein.

          (b) In the event that the Trustee shall fail to comply with the provisions of subsection (a)
of this Section with respect to the Debentures of any series the Trustee shall, within ten days
after the expiration of such 90-day period, transmit notice of such failure by mail, first class
postage prepaid, to the Debentureholders of that series as their names and addresses appear upon
the registration books. Unless the Trustee’s duty to resign is stayed as provided herein, any
Debentureholder who has been a bona fide holder of Debentures for at least six months may, on
behalf of itself and all others similarly situated, petition any court of competent jurisdiction
for the removal of the Trustee, and the appointment of a successor Trustee, if such Trustee fails,
after written request thereof by such holder to comply with the provisions of subsection (a) of
this Section.

          (c) For the purposes of this Section the Trustee shall be deemed to have a conflicting
interest with respect to the Debentures of any series if a Default has occurred and is continuing
and:

     (1) the Trustee is trustee under this Indenture with respect to the Outstanding
Debentures of any series other than that series, or is trustee under another indenture under
which any other securities, or certificates of interest or participation in any other
securities, of the Company are outstanding, unless such other indenture is a collateral
trust indenture under which the only collateral consists of Debentures issued under this
Indenture; provided that there shall be excluded from the operation of this subsection
(c)(1) the Debentures of any series other than that series and any other indenture or
indentures under which other securities, or certificates of interest or participation in
other securities, of the Company are outstanding if (i) this Indenture and such other
indenture or indentures and all series of securities issuable thereunder are wholly
unsecured and rank equally and such other indenture or indentures (and such series) are
hereafter

38

 

qualified under the Trust Indenture Act, unless the Commission shall have found and
declared by order pursuant to subsection (b) of Section 305 or subsection (c) of Section 307
of the Trust Indenture Act, that differences exist between (A) the provisions of this
Indenture with respect to Debentures of that series and with respect to one or more other
series or (B) the provisions of this Indenture and the provisions of such other indenture or
indentures (or such series), which are so likely to involve a material conflict of interest
as to make it necessary in the public interest or for the protection of investors to
disqualify the Trustee from acting as such under this Indenture with respect to the
Debentures of that series and such other series or such other indenture or indentures, or
(ii) the Company shall have sustained the burden of proving, on application to the
Commission and after opportunity for hearing thereon, that the trusteeship under this
Indenture with respect to Debentures of that series and such other series or such other
indenture or indentures is not so likely to involve a material conflict of interest as to
make it necessary in the public interest or for the protection of investors to disqualify
the Trustee from acting as such under this Indenture with respect to Debentures of that
series and such other series or under such other indentures;

     (2) the Trustee or any of its directors or executive officers is an underwriter for the
Company;

     (3) the Trustee directly or indirectly controls or is directly or indirectly controlled
by or is under direct or indirect common control with an underwriter for the Company;

     (4) the Trustee or any of its directors or executive officers is a director, officer,
partner, employee, appointee or representative of the Company, or of an underwriter (other
than the Trustee itself) for the Company who is currently engaged in the business of
underwriting, except that (A) one individual may be a director and/or an executive officer
of the Trustee and a director and/or an executive officer of the Company, but may not be at
the same time an executive officer of both the Trustee and the Company; (B) if and so long
as the number of directors of the Trustee in office is more than nine, one additional
individual may be a director and/or an executive officer of the Trustee and a director of
the Company; and (C) the Trustee may be designated by the Company or by an underwriter for
the Company to act in the capacity of transfer agent, registrar, custodian, paying agent,
fiscal agent, escrow agent, or depository, or in any other similar capacity, or, subject to
the provisions of subsection (c)(1) of this Section, to act as trustee, whether under an
indenture or otherwise;

     (5) 10% or more of the voting securities of the Trustee is beneficially owned either by
the Company or by any director, partner, or executive officer thereof, or 20% or more of
such voting securities is beneficially owned, collectively, by any two or more of such
persons; or 10% or more of the voting securities of the Trustee is beneficially owned either
by an underwriter for the Company or by any director, partner, or executive officer thereof,
or is beneficially owned, collectively, by any two or more such persons;

     (6) the Trustee is the beneficial owner of, or holds as collateral security for an
obligation which is in default (as hereinafter in this subsection (c) defined), (A) 5% or

39

 

more of the voting securities, or 10% or more of any other class of security, of the
Company, not including the Debentures issued under this Indenture and securities issued
under any other indenture under which the Trustee is also trustee, or (B) 10% or more of any
class of security of an underwriter for the Company;

     (7) the Trustee is the beneficial owner of, or holds as collateral security for an
obligation which is in default (as hereinafter in this subsection (c) defined), 5% or more
of the voting securities of any person who, to the knowledge of the Trustee, owns 10% or
more of the voting securities of, or controls directly or indirectly or is under direct or
indirect common control with, the Company;

     (8) the Trustee is the beneficial owner of, or holds as collateral security for an
obligation which is in default (as hereinafter in this subsection (c) defined), 10% or more
of any class of security of any person who, to the knowledge of the Trustee, owns 50% or
more of the voting securities of the Company;

     (9) the Trustee owns, on the date of Default upon the Debentures of any series or any
anniversary of such Default while such Default upon the Debentures issued under this
Indenture remains Outstanding, in the capacity of executor, administrator, testamentary or
inter vivos trustee, guardian, committee or conservator, or in any other similar capacity,
an aggregate of 25% or more of the voting securities, or of any class of security, of any
person, the beneficial ownership of a specified percentage of which would have constituted a
conflict interest under subsection (c)(6), (c)(7) or (c)(8) of this Section. As to any such
securities of which the Trustee acquired ownership through becoming executor, administrator
or testamentary trustee of an estate which includes them, the provisions of the preceding
sentence shall not apply for a period of not more than two years from the date of such
acquisition, to the extent that such securities in such estate do not exceed 25% of such
voting securities or 25% of any such class of security. Promptly after the dates of any
such Default upon the Debentures issued under this Indenture and annually in each succeeding
year that the Debentures issued under this Indenture remain in Default, the Trustee shall
make a check of its holding of such securities in any of the above-mentioned capacities as
of such dates. If the Company fails to make payment in full of principal of or interest on
any of the Debentures when and as the same becomes due and payable, and such failure
continues for 30 days thereafter, the Trustee shall make a prompt check of its holding of
such securities in any of the above-mentioned capacities as of the date of the expiration of
such 30-day period, and after such date, notwithstanding the foregoing provisions of this
subsection (c)(9), all such securities so held by the Trustee, with sole or joint control
over such securities vested in it, shall, but only so long as such failure shall continue,
be considered as though beneficially owned by the Trustee for the purposes of subsections
(c)(6), (c)(7) and (c)(8) of this Section; or

     (10) except under the circumstances described in subsections (b)(1), (b)(3), (b)(4),
(b)(5) or (b)(6) of Section 7.13 the Trustee shall be or shall become a creditor of the
Company.

40

 

          For purposes of subsection (c)(1) of this Section, and Section 6.06, the term “series of
securities” or “securities” means a series, class or group of securities issuable under an
indenture pursuant to whose terms holders of one such series may vote to direct the indenture
trustee, or otherwise take action pursuant to a vote of such holders, separately from holders of
another such series; provided, that, “series of securities” or “series” shall not include any
series of securities issuable under an indenture if all such series rank equally and are wholly
secured.

          The specification of percentages in subsections (c)(5) to (c)(9), inclusive, of this Section
shall not be construed as indicating that the ownership of such percentages of securities of a
person is or is not necessary or sufficient to constitute direct or indirect control for the
purposes of subsections (c)(3) or (c)(7) of this Section.

          For the purposes of subsections (c)(6), (c)(7), (c)(8) and (c)(9) of this Section only, (A)
the terms “security” and “securities” shall include only such securities as are generally known as
corporate securities, but shall not include any note or other evidence of indebtedness issued to
evidence an obligation to repay moneys lent to a person by one or more banks, trust companies or
banking firms, or any certificate of interest or participation in any such note or evidence of
indebtedness; (B) an obligation shall be deemed to be in “default”, when a default in payment of
principal shall have continued for 30 days or more and shall not have been cured; and (C) the
Trustee shall not be deemed to be the owner or holder of (i) any security which it holds as
collateral security (as trustee or otherwise) for any obligation which is not in default as defined
in clause (B) above, or (ii) any security which it holds as collateral security under this
Indenture, irrespective of any Default hereunder, or (iii) any security which it holds as agent for
collection, or as custodian, escrow agent or depositary, or in any similar representative capacity.

          (d) For the purposes of this Section 7.08:

     (1) The term “underwriter” when used with reference to the Company shall mean every
person, who, within one year prior to the time as of which the determination is made, has
purchased from the Company with a view to, or has offered or sold for the Company in
connection with, the distribution of any security of the Company, or has participated or has
had a direct or indirect participation in any such undertaking, or has participated or has
had a participation in the direct or indirect underwriting of any such undertaking, but such
term shall not include a person whose interest was limited to a commission from an
underwriter or dealer not in excess of the usual and customary distributors’ or sellers’
commission.

     (2) The term “director” shall mean any member of the board of directors of a
corporation or any individual performing similar functions with respect to any organization
whether incorporated or unincorporated.

     (3) The term “person” shall mean an individual, a corporation, a partnership, an
association, a joint-stock company, a trust, an unincorporated organization or a government
or political subdivision thereof. As used in this paragraph, the term “trust” shall include
only a trust where the interest or interests of the beneficiary or beneficiaries are
evidenced by a security.

41

 

     (4) The term “voting security” shall mean any security presently entitling the owner or
holder thereof to vote in the direction or management of the affairs of a person, or any
security issued under or pursuant to any trust, agreement or arrangement whereby a trustee
or trustees or agent or agents for the owner or holder of such security are presently
entitled to vote in the direction or management of the affairs of a person.

     (5) The term “Company” shall mean any obligor upon the Debentures.

     (6) The term “executive officer” shall mean the chairman of the board of directors,
president, every vice president, every assistant vice president, every trust officer, the
cashier, the secretary, and the treasurer of a corporation, and any individual customarily
performing similar functions with respect to any organization whether incorporated or
unincorporated.

          (e) The percentages of voting securities and other securities specified in this Section shall
be calculated in accordance with the following provisions:

     (1) A specified percentage of the voting securities of the Trustee, the Company or any
other person referred to in this Section (each of whom is referred to as a “person” in this
paragraph) means such amount of the outstanding voting securities of such person as entitles
the holder or holders thereof to cast such specified percentage of the aggregate votes which
the holders of all the outstanding voting securities of such person are entitled to cast in
the direction or management of the affairs of such person.

     (2) A specified percentage of a class of securities of a person means such percentage
of the aggregate amount of securities of the class outstanding.

     (3) The term “amount”, when used in regard to securities, means the principal amount if
relating to evidences of indebtedness, the number of shares if relating to capital shares
and the number of units if relating to any other kind of security.

     (4) The term “outstanding” means issued and not held by or for the account of the
issuer. The following securities shall not be deemed outstanding within the meaning of this
definition:

     (i) securities of an issuer held in a sinking fund relating to securities of
the issuer of the same class;

     (ii) securities of an issuer held in a sinking fund relating to another class
of securities of the issuer, if the obligation evidenced by such other class of
securities is not in default as to principal or interest or otherwise;

     (iii) securities pledged by the issuer thereof as security for an obligation of
the issuer not in default as to principal or interest or otherwise; and

     (iv) securities held in escrow if placed in escrow by the issuer thereof,
provided, however, that any voting securities of an issuer shall be deemed

42

 

outstanding if any person other than the issuer is entitled to exercise the
voting rights thereof.

     (5) A security shall be deemed to be of the same class as another security if both
securities confer upon the holder or holders thereof substantially the same rights and
privileges; provided, however, that, in the case of secured evidences of indebtedness, all
of which are issued under a single indenture, differences in the interest rates or maturity
dates of various series thereof shall not be deemed sufficient to constitute such series
different classes; and provided, further, that, in the case of unsecured evidences of
indebtedness, differences in the interest rates or maturity dates thereof shall not be
deemed sufficient to constitute them securities of different classes, whether or not they
are issued under a single indenture.

          (f) Except in the case of a default in the payment of the principal of (or premium, if any) or
interest on any Debentures issued under this Indenture, or in the payment of any sinking or
analogous fund installment, the Trustee shall not be required to resign as provided by this
Section.7.08 if such Trustee shall have sustained the burden of proving, on application to the
Commission and after opportunity for hearing thereon, that (i) the default under the Indenture may
be cured or waived during a reasonable period and under the procedures described in such
application and (ii) a stay of the Trustee’s duty to resign will not be inconsistent with the
interests of Debentureholders. The filing of such an application shall automatically stay the
performance of the duty to resign until the Commission orders otherwise.

          Any resignation of the Trustee shall become effective only upon the appointment of a successor
trustee and such successor’s acceptance of such an appointment.

     SECTION 7.09. Requirements for Eligibility.

          There shall at all times be a Trustee with respect to the Debentures 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 Commission, authorized under such
laws to exercise corporate trust powers, having a combined capital arid surplus of at least
$50,000,000.00, and subject to supervision or examination by Federal, State, Territorial, or
District of Columbia authority. If such corporation publishes reports of condition at least
annually, pursuant to law or to the requirements of the aforesaid supervising or examining
authority, then for the purposes of this Section, the combined capital and surplus of such
corporation shall be deemed to be its combined capital and surplus as set forth in its most recent
report of condition so published. The Company may not, nor may any person directly or indirectly
controlling, controlled by, or under common control with the Company, serve as Trustee. In case at
any time the Trustee shall cease to be eligible in accordance with the provisions of this Section,
the Trustee shall resign immediately in the manner and with the effect specified in Section 7.10.

43

 

     SECTION 7.10. Resignation and Removal.

          (a) The Trustee or any successor hereafter appointed, may at any time resign with respect to
the Debentures 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 Debentureholders of
such series, as their names and addresses appear upon the Debenture Register. Upon receiving such
notice of resignation, the Company shall promptly appoint a successor trustee with respect to
Debentures 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 Debentures of such series, or any Debentureholder of that series who has been a bona
fide holder of a Debenture or Debentures for at least six months may, subject to the provisions of
Section 6.08, 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, appointment a successor trustee.

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

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

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

     (3) the Trustee shall become incapable of acting, or shall be adjudged a bankrupt or
insolvent, or a receiver of the Trustee or of its property shall be appointed, or any public
officer shall take charge or control of the Trustee or of its property or affairs for the
purpose of rehabilitation, conservation or liquidation, then, in any such case, the Company
may remove the Trustee with respect to all Debentures 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, subject to the provisions of Section 6.08, unless the Trustee’s duty to resign
is stated as provided herein, any Debentureholder who has been a bona fide holder of a
Debenture or Debentures for at least six months may, on behalf of himself and all others
similarly situated, petition any court of competent jurisdiction for the removal of the
Trustee and the appointment of a successor trustee. 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 Debentures of any series at
the time Outstanding may at any time remove the Trustee with respect to such series and appoint a
successor trustee with respect to the Debentures of such series by delivering

44

 

to the Trustee so removed, to the successor so appointed and to the Company the evidence
provided for in Section 8.01 of the action in that regard to be taken by the Debentureholders.

          (d) Any resignation or removal of the Trustee and appointment of a successor trustee with
respect to the Debentures 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 Debentures of one or more series or all of such series, and at any time there shall be only one
Trustee with respect to the Debentures 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
Debentures, 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 Debentures
of one or more (but not all) series, the Company, the retiring Trustee and each successor trustee
with respect to the Debentures of one or more series shall execute and deliver an indenture
supplemental hereto wherein each successor trustee shall accept such appointment and which (1)
shall contain such provisions as shall be necessary or desirable to transfer and confirm to, and to
vest in, each successor trustee all the rights, powers, trusts and duties of the retiring Trustee
with respect to the Debentures of that or those series to which the appointment of such successor
trustee relates, (2) shall contain such provisions as shall be deemed necessary or desirable to
confirm that all the rights, powers, trusts and duties of the retiring Trustee with respect to the
Debentures of that or those series as to which the retiring Trustee is not retiring shall continue
to be vested in the retiring Trustee, and (3) shall add to or change any of the provisions of this
Indenture as shall be necessary to provide for or facilitate the administration of the trusts
hereunder by more than one Trustee, it being understood that nothing herein or in such supplemental
indenture shall constitute such Trustees co-trustees of the same trust, that each such Trustee
shall be trustee of a trust or trusts hereunder separate and apart from any trust or trusts
hereunder administered by any other such Trustee and that no Trustee shall be responsible for any
act or failure to act on the part of any other Trustee hereunder; and upon the execution and
delivery of such supplemental indenture the resignation or removal of the retiring Trustee shall
become effective to the extent provided therein, such retiring Trustee shall with respect to the
Debentures 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,

45

 

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 Debentures 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 Debentures 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, power and trusts referred to in subsections (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 Debentureholders, as their names and addresses appear upon the Debenture
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. Successor to Trustee by Merger, Consolidation or Succession to
Business.

          Any corporation into which the Trustee may be merged or converted or with which it may be
consolidated, or any corporation resulting from any merger, conversion or consolidation to which
the Trustee shall be a party, or any corporation succeeding to all or substantially all the
corporate trust business of the Trustee, shall be the successor of the Trustee hereunder, provided
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
Debentures 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 Debentures so authenticated with the same effect as if such
successor Trustee had itself authenticated such Debentures.

     SECTION 7.13. Preferential Collection of Claims Against Issuer.

          (a) Subject to the provisions of subsection (b) of this Section, if the Trustee shall be or
shall become a creditor, directly or indirectly, secured or unsecured, of the Company within three
months prior to a default, as defined in subsection (b) of this Section, or subsequent to such a
default, then, unless and until such default shall be cured, the Trustee shall set apart and hold
in a special account for the benefit of the Trustee individually, the holders of the Debentures and
the holders of other indenture securities (as defined in subsection (c) of this Section):

46

 

     (1) an amount equal to any and all reductions in the amount due and owing upon any
claim as such creditor in respect of principal or interest, effected after the beginning of
such three months’ period and valid as against the Company and its other creditors, except
any such reduction resulting from the receipt or disposition of any property described in
subsection (a)(2) of this Section, or from the exercise of any right of set-off which the
Trustee could have exercised if a petition in bankruptcy had been filed by or against the
Company upon the date of such default; and

     (2) all property received by the Trustee in respect of any claim as such creditor,
either as security therefor, or in satisfaction or composition thereof, or otherwise, after
the beginning of such three months’ period, or an amount equal to the proceeds of any such
property, if disposed of, subject, however, to the rights, if any, of the Company and its
other creditors in such property or such proceeds.

          Nothing herein contained, however, shall affect the right of the Trustee:

          (A) to retain for its own account (i) payments made on account of any such claim by any person
(other than the Company) who is liable thereon, and (ii) the proceeds of the bona fide sale of any
such claim by the Trustee to a third person, and (iii) distributions made in cash, securities, or
other property in respect of claims filed against the Company in bankruptcy or receivership or in
proceedings for reorganization pursuant to the Federal Bankruptcy Code or applicable State law;

          (B) to realize, for its own account, upon any property held by it as security for any such
claim, if such property was so held prior to the beginning of such three months’ period;

          (C) to realize, for its own account, but only to the extent of the claim hereinafter
mentioned, upon any property held by it as security for any such claim, if such claim was created
after the beginning of such three months’ period and such property was received as security
therefor simultaneously with the creation thereof, and if the Trustee shall sustain the burden of
proving that at the time such property was so received the Trustee had no reasonable cause to
believe that a default, as defined in subsection (c) of this Section, would occur within three
months; or

          (D) to receive payment on any claim referred to in paragraph (B) or (C) above, against the
release of any property held as security for such claim as provided in such paragraph (B) or (C),
as the case may be, to the extent of the fair value of such property.

          For the purposes of paragraphs (B), (C) and (D) above, property substituted after the
beginning of such three months’ period for property held as security at the time of such
substitution shall, to the extent of the fair value of the property released, have the same status
as the property released, and, to the extent that any claim referred to in any of such paragraphs
is created in renewal of or in substitution for or for the purpose of repaying or refunding any
preexisting claim of the Trustee as such creditor, such claim shall have the same status as such
pre-existing claim.

          If the Trustee shall be required to account, the funds and property held in such special
account and the proceeds thereof shall be apportioned between the Trustee, the

47

 

Debentureholders and the holders of other indenture securities in such manner that the
Trustee, the Debentureholders and the holders of other indenture securities realize, as a result of
payments from such special account and payments of dividends on claims filed against the Company in
bankruptcy or receivership or proceedings for reorganization pursuant to the Federal Bankruptcy
Code or applicable State law, the same percentage of their respective claims, figured before
crediting to the claim of the Trustee anything on account of the receipt by it from the Company of
the funds and property in such special account and before crediting to the respective claims of the
Trustee, the Debentureholders and the holders of other indenture securities dividends on claims
filed against the Company in bankruptcy or receivership or proceedings for reorganization pursuant
to the Federal Bankruptcy Code or applicable State law, but after crediting thereon receipts on
account of the indebtedness represented by their respective claims from all sources other than from
such dividends and from the funds and property so held in such special account. As used in this
paragraph, with respect to any claim, the term “dividends” shall include any distribution with
respect to such claim, in bankruptcy or receivership or proceedings for reorganization pursuant to
the Federal Bankruptcy Code or applicable State law, whether such distribution is made in cash,
securities, or other property, but shall not include any such distribution with respect to the
secured portion, if any, of such claim. The court in which such bankruptcy, receivership or
proceedings for reorganization is pending shall have jurisdiction (i) to apportion between the
Trustee, the Debentureholders and the holders of other indenture securities, in accordance with the
provisions of this paragraph, the funds and property held in such special account and the proceeds
thereof, or (ii) in lieu of such apportionment, in whole or in part, to give to the provisions of
this paragraph due consideration in determining the fairness of the distributions to be made to the
Trustee, the Debentureholders and the holders of other indenture securities with respect to their
respective claims, in which event it shall not be necessary to liquidate or to appraise the value
of any securities or other property held in such special account or as security for any such claim,
or to make a specific allocation of such distributions as between the secured and unsecured
portions of such claims, or otherwise to apply the provisions of this paragraph as a mathematical
formula.

          Any Trustee who has resigned or been removed after the beginning of such three months’ period
shall be subject to the provisions of this subsection (a) as though such resignation or removal had
not occurred. If any Trustee has resigned or been removed prior to the beginning of such three
months’ period, it shall be subject to the provisions of this subsection (a) if and only if the
following conditions exist:

          (i) the receipt of property or reduction of claim which would have given rise to the
obligation to account, if such Trustee had continued as trustee, occurred after the beginning of
such three months’ period; and

          (ii) such receipt of property or reduction of claim occurred within three months after such
resignation or removal.

          In any case commenced under the Bankruptcy Act of July 1, 1898, or any amendment thereto
enacted prior to November 6, 1978, all references to periods of three months in subsection (a) of
this Section shall be deemed to be references to periods of four months.

48

 

          (b) There shall be excluded from the operation of subsection (a) of this Section a creditor
relationship arising from:

     (1) the ownership or acquisition of securities issued under any indenture, or any
security or securities having a maturity of one year or more at the time of acquisition by
the Trustee;

     (2) advances authorized by a receivership or bankruptcy court of competent
jurisdiction, or by this Indenture, for the purpose of preserving any property which shall
at any time be subject to the lien, if any, of this Indenture or of discharging tax liens or
other prior liens or encumbrances thereon, if notice of such advance and of the
circumstances surrounding the making thereof is given to the Debentureholders at the time
and in the manner provided in this Indenture;

     (3) disbursements made in the ordinary course of business in the capacity of trustee
under an indenture, transfer agent, registrar, custodian, paying agent, subscription agent,
fiscal agent or depositary, or other. similar capacity;

     (4) an indebtedness created as a result of services rendered or premises rented; or an
indebtedness created as a result of goods or securities sold in a cash transaction as
defined in subsection (c) of this Section;

     (5) the ownership of stock or of other securities of a corporation organized under the
provisions of Section 25(a) of the Federal Reserve Act, as amended, which is directly or
indirectly a creditor of the Company; or

     (6) the acquisition, ownership, acceptance or negotiation of any drafts, bills of
exchange, acceptances or obligations which fall within the classification of
self-liquidating paper as defined in subsection (c) of this Section.

          (c) As used in this Section:

     (1) The term “default” shall mean any failure to make payment in full of the principal
of (or premium, if any) or interest upon any of the Debenture or upon the other indenture
securities when and as such principal (or premium, if any) or interest becomes due and
payable.

     (2) The term “other indenture securities” shall mean securities upon which the Company
is an obligor (as defined in the Trust Indenture Act) outstanding under any other indenture
(A) under which the Trustee is also trustee, (B) which contains provisions substantially
similar to the provisions of subsection (a) of this Section, and (C) under which a default
exists at the time of the apportionment of the funds and property held in said special
account.

     (3) The term “cash transaction” shall mean any transaction in which full payment for
goods or securities sold is made within seven days after delivery of the goods or securities
in currency or in checks or other orders drawn upon banks or bankers and payable upon
demand.

49

 

     (4) The term “self-liquidating paper” shall mean any draft, bill of exchange,
acceptance or obligation which is made, drawn, negotiated or incurred by the Company for the
purpose of financing the purchase, processing, manufacture, shipment, storage or sale of
goods, wares or merchandise and which is secured by documents evidencing title to,
possession of, or a lien upon, the goods, wares or merchandise or the receivables or
proceeds arising from the sale of the goods, wares or merchandise previously constituting
the security, provided the security is received by the Trustee simultaneously with the
creation of the creditor relationship with the Company arising from the making, drawing,
negotiating or incurring of the draft, bill of exchange, acceptance or obligation.

     (5) The term “Company” shall mean any obligor upon any of the Debentures.

ARTICLE EIGHT

Concerning the Debentureholders

     SECTION 8.01. Evidence of Action by Debentureholders.

          Whenever in this Indenture it is provided that the holders of a majority or specified
percentage in aggregate principal amount of the Debentures 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 Debentures of
that series in person or by agent or proxy appointed in writing.

          If the Company shall solicit from the Debentureholders of any series any request, demand,
authorization, direction, notice, consent, waiver or other action, the Company may, at its option,
as evidenced by an Officer’s Certificate, fix in advance a record date for such series for the
determination of Debentureholders 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 Debentureholders
of record at the close of business on the record date shall be deemed to be Debentureholders for
the purposes of determining whether Debentureholders of the requisite proportion of Outstanding
Debentures 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 Debentures of that series shall be computed as of the record date; provided that no
such authorization, agreement or consent by such Debentureholders 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.

          In the event a Debenture is held by a Hawaiian Electric Industries Capital Trust and the
approval or consent of said Trust as a holder of the Debenture is required under any provision of
this Indenture, or any action is to be taken by said Trust as a holder of a Debenture under any
provision of this Indenture, the approval or consent of, or action by, said Trust will be subject
to any approval and other requirements of the applicable Trust Agreement.

50

 

     SECTION 8.02. Proof of Execution of Instruments and of Holding of Debentures.

          Subject to the provisions of Section 7.01, proof of the execution of any instrument by a
Debentureholder or the Debentureholder’s agent or proxy and proof of the holding by any person of
any of the Debentures 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 Debentures shall be proved by the Debenture Register of such Debentures
or by a certificate of the Debenture Registrar thereof.

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

     SECTION 8.03. Persons Deemed Owners of Debentures.

          Prior to the due presentment for registration of transfer of any Debenture, the Company, the
Trustee, any paying agent and any Debenture Registrar may deem and treat the person in whose name
such Debenture shall be registered upon the books of the Company as the absolute owner of such
Debenture (whether or not such Debenture shall be overdue and notwithstanding any notice of
ownership or writing thereon made by anyone other than the Debenture 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 Debenture and for all other purposes; and neither the Company nor the
Trustee nor any paying agent nor any Debenture Registrar shall be affected by any notice to the
contrary.

     SECTION 8.04. Debentures Owned by Company or Controlled or Controlling Companies
Disregarded for Certain Purposes.

          In determining whether the holders of the requisite aggregate principal amount of Debentures
of a particular series have concurred in any direction, consent or waiver under this Indenture,
Debentures of that series which are owned by the Company or any other obligor on the Debentures of
that series or by any Subsidiary of the Company or of such other obligor on the Debentures 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 Debentures of such series which the Trustee
actually knows are so owned shall be so disregarded. Debentures so owned which 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
Debentures and that the pledgee is not a Person directly or indirectly controlling or controlled by
or under direct or indirect common control with or an Affiliate of 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.

51

 

     SECTION 8.05. Instruments Executed by Debentureholders Bind Future Holders.

          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 Debentures of a particular series specified in this Indenture in connection
with such action, any holder of a Debenture of that series which is shown by the evidence to be
included in the Debentures 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 Debenture. Except as aforesaid any such action taken by the holder
of any Debenture shall be conclusive and binding upon such holder and upon all future holders and
owners of such Debenture, and of any Debenture 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 Debenture. Any action taken by the holders of the majority or percentage in
aggregate principal amount of the Debentures 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 Debentures of that series.

ARTICLE NINE

Supplemental Indentures

     SECTION 9.01. Supplemental Indentures Without Consent of Debentureholders.

          In addition to any supplemental indenture otherwise authorized by this Indenture, 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), without the consent of the Debentureholders, for one or
more of the following purposes:

          (a) to evidence the succession of another corporation to the Company, and the assumption by
any such successor of the covenants of the Company contained herein or otherwise established with
respect to the Debentures; or

          (b) to add to the covenants of the Company such further covenants, restrictions, conditions or
provisions for the protection of the holders of the Debentures of all or any series as the Board of
Directors and the Trustee shall consider to be for the protection of the holders of Debentures of
all or any series, and to make the occurrence, or the occurrence and continuance, of a Default in
any of such additional covenants, restrictions, conditions or provisions a Default or an Event of
Default with respect to such series permitting the enforcement of all or any of the several
remedies provided in this Indenture as herein set, forth; provided, however, that in respect of any
such additional covenant, restriction, condition or provision such supplemental indenture may
provide for a particular period of grace after Default (which period may be shorter or longer than
that allowed in the case of other Defaults) or may provide for an immediate enforcement upon such
Default or may limit the remedies available to

52

 

the Trustee upon such Default or may limit the right of the holders of a majority in aggregate
principal amount of the Debentures of such series to waive such Default; or

          (c) to cure any ambiguity or to correct or supplement any provision contained herein or in any
supplemental indenture which may be defective or inconsistent with any other provision contained
herein or in any supplemental indenture, or to make such other provisions in regard to matters or
questions arising under this Indenture as shall not be inconsistent with the provisions of this
Indenture and shall not adversely affect the interests of the holders of the Debentures of any
series; or

          (d) to change or eliminate any of the provisions of this Indenture, provided that any such
change or elimination shall become effective only when there is no Debenture Outstanding of any
series created prior to the execution of such supplemental indenture which is entitled to the
benefit of such provision.

          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 which may
be therein contained, but the Trustee shall not be obligated to enter into any such supplemental
indenture which affects the Trustee’s own rights, duties or immunities under this Indenture or
otherwise.

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

     SECTION 9.02. Modification of Indenture With Consent of Debentureholders.

          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 Debentures of each series affected 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 the rights of the holders of the
Debentures of such series under this Indenture; provided, however, that no such supplemental
indenture shall, without the consent of the holders of each Debenture then Outstanding and affected
thereby, (i) extend the fixed maturity of any Debentures of any series, or reduce the principal
amount thereof (including in the case of a discounted Debenture the amount payable thereon in the
event of acceleration or the amount provable in bankruptcy) or any premium thereon, or reduce the
rate or extend the time of payment of interest thereon, or reduce any amount payable upon the
redemption thereof, or make the principal of’ or interest or premium, if any, on the Debentures
payable in any coin or currency other than that provided in the Debentures, or impair or affect the
right of any Debentureholder to institute suit for the payment thereof or the right of prepayment,
if any, at the option of the Debentureholder, (ii) reduce the aforesaid percentage of Debentures,
the holders of which are required to consent to

53

 

any such modification, or (iii) otherwise adversely affect the interest of the holders of any
series of Debentures.

          Upon the request of the Company, accompanied by a Board Resolution authorizing the execution
of any such supplemental indenture, and upon the filing with the Trustee of evidence of the consent
of Debentureholders 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.

          It shall not be necessary for the consent of the Debentureholders 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.

          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 Debentureholders of all series affected thereby as their names and addresses appear upon the
Debenture 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.

     SECTION 9.03. Effect of Supplemental Indentures.

          Upon the execution of any supplemental indenture pursuant to the provisions of this Article or
Section 10.01, this Indenture shall, with respect to such series, be and be deemed to be modified
and amended in accordance therewith and the respective rights, limitations of rights, obligations,
duties and immunities under this Indenture of the Trustee, the Company and the holders of
Debentures 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. Debentures May Bear Notation of Changes by Supplemental
Indentures.

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

54

 

     SECTION 9.05. Opinion of Counsel.

          The Trustee, subject to the provisions of Section 7.01, may receive an Opinion of Counsel as
conclusive evidence that any supplemental indenture executed pursuant to this Article is authorized
or permitted by, and conforms to, the terms of this Article and that it is proper for the Trustee
under the provisions of this Article to join in the execution thereof.

in right of payment to the payment in full of all Senior Indebtedness, which is not subordinate in
right of payment to the Debentures and which by its terms grants such right of subrogation to the
holder thereof) shall be subrogated to the rights of the holders of Senior
Indebtedness to receive payments or distributions of assets or securities of the Company
applicable to the Senior Indebtedness until the. Debentures shall be paid in full, and, for the
purposes of such subrogation, no such payments or distributions to the holders of Senior
Indebtedness of assets or securities, which otherwise would have been payable or distributable to
holders of Debentures, shall, as between the Company, its creditors other than the holders of
Senior Indebtedness, and the holders, be deemed to be a payment by the Company to or on account of
the Senior Indebtedness, it being understood that the provisions of this Article Fourteen are and
are intended solely for the purpose of defining the relative rights of the holders, on the one
hand, and the holders of the Senior Indebtedness, on the other hand, and nothing contained in this
Article Fourteen or elsewhere in this Indenture or in the Debentures is intended to or shall impair
as between the Company, its creditors other than the holders of Senior Indebtedness, and the
holders, the obligation of the Company, which is unconditional and absolute, to pay to the holders
the principal of and interest on the Debentures as and when the same shall become due and payable
in accordance with their terms, or to affect the relative rights

65

 

of the holders and creditors of
the Company other than the holders of the Senior Indebtedness, nor shall anything herein or therein
prevent the Trustee or the holder of any Debenture from exercising all remedies otherwise permitted
by applicable law upon Default under this Indenture subject to the rights of the holders of Senior
Indebtedness, under Section 14.02, to receive cash, property or securities of the Company otherwise
payable or deliverable to the holders of the Debentures.

          Upon any distribution or payment in connection with any proceedings or sale referred to in
subsection (a) of Section 14.02, the Trustee, subject as between the Trustee and the holders to the
provisions of Sections 7.01 and 7.02 hereof, shall be entitled to rely upon a certificate of the
liquidating trustee or agent or other person making any distribution or payment to the Trustee for
the purpose of ascertaining the holders of Senior Indebtedness entitled to participate in such
payment or distribution, the amount of such Senior Indebtedness or the amount payable thereon, the
amount or amounts paid or distributed thereon and all other facts pertinent thereto or to this
Article Fourteen. In the event that the Trustee determines, in good faith, that further evidence
is required with respect to the right of any person as a holder of Senior Indebtedness to
participate in any payment or distribution pursuant to this Section 14.03, the Trustee may request
such person to furnish evidence to the reasonable satisfaction of the Trustee as to the amount of
Senior Indebtedness held by such person, as to the extent to which such person is entitled to
participate in such payment or distribution, and as to other facts pertinent to the rights of such
person under this Section 14.03, and if such evidence is not furnished, the Trustee may defer any
payment to such person pending judicial determination as to the right of such person to receive
such payment.

          The Trustee, however, shall not be deemed to owe any fiduciary duty to the holders of Senior
Indebtedness, and shall not be liable to any such holders if it shall in good faith pay over or
distribute to holders of Debentures or the Company or any other person moneys or assets to which
any holders of Senior Indebtedness shall be entitled by virtue of Article Fourteen of this
Indenture or otherwise. With respect to the holders of Senior Indebtedness, the Trustee undertakes
to perform or to observe only such of its covenants or obligations as are specifically set forth in
this Article and no implied covenants or obligations with respect to holders of Senior Indebtedness
shall be read into this Indenture against the Trustee.

     SECTION 14.04. Payments to Debentureholders.

          Nothing contained in this Article Fourteen or elsewhere in this Indenture, or in any of the
Debentures, shall prevent at any time, (a) the Company from making payments at any time of
principal of or interest on the Debentures, except under the conditions described in Section 14.02
or during the pendency of any proceedings or sale therein referred to, provided, however, that
payments of principal of or interest on the Debentures shall only be made by the Company within
three business days of the due dates for such payments or (b) the application by the Trustee of any
moneys deposited with it hereunder to the payment of or on account of the principal of or interest
on the Debentures, if at the time of such deposit the Trustee did not have written notice in
accordance with Section 14.06 of any event prohibiting the making of such deposit by the Company or
if in the event of redemption, the Trustee did not have such written notice prior to the time that
the notice of redemption pursuant to Section 3.02 was given (which

66

 

notice of redemption shall in no
event be given more than 60 days prior to the date fixed for redemption).

			
	      SECTION 14.05.	 	Holders of Debentures Authorize Trustee to Effectuate
Subordination of Debentures.

          Each Debentureholder by its acceptance of a Debenture authorizes and directs the Trustee on
its behalf to take such action as may be necessary or appropriate to acknowledge or effectuate the
subordination as provided in this Article Fourteen and appoints the Trustee as attorney-in-fact for
any and all such purposes, including, in the event of any dissolution, winding up, liquidation or
reorganization of the Company (whether in bankruptcy, insolvency or receivership proceedings or
upon an assignment for the benefit of creditors or otherwise) tending towards liquidation of the
business and assets of the Company, the immediate filing of a claim for the unpaid balance of such
Debentureholder’s Debentures in the form required in said proceedings and cause said claim to be
approved.

     SECTION 14.06. Notice to Trustee.

          Notwithstanding the provisions of this Article Fourteen or any other provisions of this
Indenture, the Trustee shall not be charged with the knowledge of the existence of any facts which
would prohibit the making of any payment of moneys to the Trustee, unless and until the Trustee
shall have received written notice thereof from the Company or from the holder or the
representative of any class of Senior Indebtedness; provided, however, that if at least two
business days prior to the date upon which by the terms hereof any such monies may become payable
for any purpose (including, without limitation, the payment of either the cash amount payable at
maturity or interest on any Debenture) the Trustee shall not have received with respect to such
monies the notice provided for in this Section 14.06, then, anything herein contained to the
contrary notwithstanding, the Trustee shall have full power and authority to receive such monies
and to apply the same to the purpose for which they were received, and shall not be affected by any
notice to the contrary, which may be received by it on or after such two business days prior to
such date.

     SECTION 14.07. Trustees May Hold Senior Indebtedness.

          The Trustee shall be entitled to all the rights set forth in this Article Fourteen with
respect to any Senior Indebtedness which may at any time be held by it, to the same extent as any
other holder of Senior Indebtedness.

     SECTION 14.08. Not Applicable to Trustee’s Compensation and Reimbursement.

          Nothing in this Article Fourteen shall apply to claims of, or payments to, the Trustee under
or pursuant to Section 7.06.

     SECTION 14.09. Applicability of Article Fourteen to Paying Agents.

          In case at any time any paying agent other than the Trustee shall be appointed by the Company
and be then acting hereunder, the term “Trustee” as used in this Article Fourteen

67

 

shall in such
case (unless the context shall otherwise require) be construed as extending to and including such
paying agent within its meaning as fully for all intents and purposes as if such paying agent were
named in this Article Fourteen in place of the Trustee.

          U.S. Bank National Association, as Trustee, hereby accepts the trust in this Indenture
declared and provided, upon the terms and conditions hereinabove set forth.

          IN WITNESS WHEREOF, the parties hereto have caused this Indenture to be duly executed, all as
of the day and year first above written.

HAWAIIAN ELECTRIC INDUSTRIES, INC.

______% JUNIOR SUBORDINATED DEBENTURE, SERIES ___ DUE ______

_________ PRINCIPAL AMOUNT

     HAWAIIAN ELECTRIC INDUSTRIES, INC., a Hawaii corporation (the “Company”, which term includes
any successor corporation under the Indenture hereinafter referred to), for value received, hereby
promises to pay to ____________ or registered assigns, the principal sum of
____________ Dollars ($____________) on ____________, ______(the “Stated Maturity”), and to pay
interest on said principal sum from the original date of issuance or from the most recent interest
payment date (each such date, an “Interest Payment Date”) to which interest has been paid or duly
provided for, quarterly (subject to deferral as set forth herein) in arrears on ____________,
____________, ____________and ____________ of each year commencing _______________, ______, at the rate of ______%
per annum, plus Additional Interest, if any, until the principal hereof shall have become due and
payable, and on any overdue principal and premium, if any. The amount of interest payable on any
Interest Payment Date shall be computed on the basis of a 360-day year of twelve 30-day months.
For any period shorter than a full 90-day quarter, interest will be computed on the basis of the
actual number of days elapsed in such 90-day quarter. In the event that any date on which interest
is payable on this Debenture is not a Business Day, then payment of interest payable on such date
will be made on the next succeeding day that is a Business Day (and without any interest or other
payment in respect of any such delay), except that, if such Business Day is in the next succeeding
calendar year, such payment shall be made on the immediately preceding Business Day, in each case
with the same force and effect as if made on such date. The interest installment so payable, and
punctually paid or duly provided for, on any Interest Payment Date will, as provided in the
Indenture, be paid to the person in whose name this Debenture (or one or more Predecessor
Debentures, as defined in said Indenture) is registered at the close of business on the regular
record date for such interest installment.

     Any interest on this Debenture which is payable, but is not punctually paid or duly provided
for, on any Interest Payment Date for Debentures 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 this Debenture to the
person or persons in whose names this Debenture (or one or more Predecessor Debentures) 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 this
Debenture 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

2

 

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 Debentureholder at his or her address as it appears in the
Debenture Register, 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 person or persons in whose
names this Debenture (or one or more Predecessor Debentures) is registered on such special
record date and shall be no longer payable pursuant to the following clause (2).

     (2) The Company may make payment of any Defaulted Interest on this Debenture in any
other lawful manner not inconsistent with the requirements of any Securities Exchange on
which this Debenture 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.

     The Company shall have the right at any time during the term of this Debenture, from time to
time, to extend the interest payment period of this Debenture for up to six consecutive quarters
(an “Extension Period”), during which periods interest will compound quarterly and the Company
shall have the right to make partial payments of interest on any Interest Payment Date, and at the
end of which Extension Period the Company shall pay all interest then accrued and unpaid (together
with Additional Interest thereon to the extent that payment of such interest is permitted by
applicable law). Prior to the termination of any such Extension Period, the Company may further
extend the interest payment period, provided that such Extension Period together with all such
previous and further extensions thereof shall not exceed six consecutive quarters or extend beyond
the Stated Maturity of this Debenture. Upon the termination of any such Extension Period and upon
the payment of all accrued and unpaid interest and any Additional Interest then due, the Company
may select a new Extension Period, subject to the foregoing requirements. No interest shall be due
and payable during an Extension Period except at the end thereof. The Company shall give the
holder of this Debenture and the Trustee written notice of its selection of an Extension Period at
least one Business Day prior to the earlier of (i) the Interest Payment Date or (ii) the date
Hawaiian Electric Industries Capital Trust is required to give notice to the New York Stock
Exchange or other applicable self-regulatory organization or to holders of the Trust Preferred
Securities of the record date or the date such distributions are payable, but in any event not less
than one Business Day prior to such record date.]

     The principal of (and premium, if any) and interest on this Debenture shall be payable and
this Debenture shall be surrendered for registration of transfer or exchange at the offices and
agencies of the Company maintained for that purpose in the Borough of Manhattan, the City and State
of New York, or at such other location or locations selected by the Company, agreed to by

3

 

the Trustee and consistent with the Indenture. Payment of the principal (and premium, if any)
and interest due with respect to any Debenture at maturity will be made in immediately available
funds upon surrender of the Debenture at the place or places provided hereinabove; provided that
this Debenture is presented to the Paying Agent in time for the Paying Agent to make such payments
in such funds in accordance with its normal procedures. [Payments of interest other than at
maturity will be made at the place or places provided hereinabove; provided that payment of
interest on this Debenture if not registered to a Hawaiian Electric Industries Capital Trust may be
made at the option of the Company by check mailed to the address of the Person entitled thereto as
it appears on the Debenture Register or by wire transfer to an account appropriately designated by
the Person entitled thereto as it appears on the Debenture Register.]

     The indebtedness evidenced by this Debenture is, to the extent provided in the Indenture,
subordinate and junior in right of payment to the prior payment in full of all Senior Indebtedness,
and this Debenture is issued subject to the provisions of the Indenture with respect thereto. Each
holder of this Debenture, by accepting the same, (a) agrees to and shall be bound by such
provisions, (b) authorizes and directs the Trustee on his or her behalf to take such action as may
be necessary or appropriate to acknowledge or effectuate the subordination so provided and (c)
appoints the Trustee his or her attorney-in-fact for any and all such purposes. Each holder
hereof, by his or her acceptance hereof, hereby waives all notice of the acceptance of the
subordination provisions contained herein and in the Indenture by each holder of Senior
Indebtedness, whether now outstanding or hereafter incurred, and waives reliance by each such
holder upon said provisions.

     This Debenture shall not be entitled to any benefit under the Indenture hereinafter referred
to, be valid or become obligatory for any purpose until the Certificate of Authentication hereon
shall have been signed by or on behalf of the Trustee by manual signature.

     The provisions of this Debenture are continued on the reverse side hereof and such continued
provisions shall for all purposes have the same effect as though fully set forth at this place.

     IN WITNESS WHEREOF, the Company has caused this instrument to be executed.

attorney duly authorized in writing, and thereupon one or more new Debentures of authorized
denominations and for the same aggregate principal amount and series will be issued to the
designated transferee or transferees. No service charge will be made for any such transfer, but
the Company may require payment of a sum sufficient to cover any tax or other governmental charge
payable in relation thereto, subject to certain limitations set forth in the Indenture.

     Prior to due presentment for registration of transfer of this Debenture, the Company, the
Trustee, any Paying Agent and the Debenture Registrar may deem and treat the registered holder
hereof as the absolute owner hereof (whether or not this Debenture shall be overdue and
notwithstanding any notice of ownership or writing hereon made by anyone other than the Debenture
Registrar) for the purpose of receiving payment of or on account of the principal hereof and
premium, if any, and interest due hereon and for all other purposes, and neither the Company nor
the Trustee nor any paying agent nor any Debenture Registrar shall be affected by any notice to the
contrary.

     No recourse shall be had for the payment of the principal of or the interest on this
Debenture, or for any claim based hereon, or otherwise in respect hereof, or based on or in respect
of the Indenture, against any incorporator, stockholder, officer or director, past, present or
future, as such, of the Company or of any predecessor or successor corporation, whether by virtue
of any constitution, statute or rule of law, or by the enforcement of any assessment or penalty or
otherwise, all such liability being, by the acceptance hereof and as part of the consideration for
the issuance hereof, expressly waived and released.

     The Debentures of this series are issuable only in registered form without coupons in
denominations of $25 and any integral multiple thereof. As provided in the Indenture and subject
to certain limitations herein and therein set forth, Debentures of this series so issued are
exchangeable for a like aggregate principal amount of Debentures of this series of a different
authorized denomination, as requested by the holder surrendering the same.

     All terms used in this Debenture that are defined in the Indenture and the Officers’
Certificate shall have the meanings assigned to them in the Indenture and the Officers’
Certificate.

     This Debenture shall be governed by and construed in accordance with the laws of the State of
New York without regard to conflicts of laws principles thereof.
