instrument to which the Company is a party or by which it or any of its property
is bound;

     (F) that all consents or approvals of any other federal or state regulatory
agency required in connection with the Company's execution and delivery of this
Indenture and such series of Securities have been obtained and not withdrawn
(except that no statement need be made with respect to state securities laws);
and

     (3) an Officer's Certificate stating that (i) the Company is not, and upon
the authentication by the Trustee of the series of Securities, will not be in
default under any of the terms or covenants contained in the Indenture and (ii)
all conditions that must be met by the Company to issue Securities under this
Indenture have been met.

     (d) The Trustee shall have the right to decline to authenticate and deliver
any Security:

     (1) if the issuance of such Securities pursuant to this Indenture will
affect the Trustee's own rights, duties or immunities under the Securities and
this Indenture or otherwise in a manner that is not reasonably acceptable to the
Trustee;

     (2) if the Trustee, being advised by counsel, determines that such action
may not lawfully be taken; or

     (3) if the Trustee in good faith by its Board of Directors, executive
officers or a trust committee of directors and/or responsible officers
determines that such action would expose the Trustee to personal liability to
Holders of any outstanding Securities.

     (e) No Security shall be entitled to any benefit under this Indenture or be
valid or obligatory for any purpose unless there appears on such Security a
certificate of authentication substantially in the form provided for herein
executed by the Trustee by the manual signature of an authorized officer, and
such certificate upon any Security shall be conclusive evidence, and the only
evidence, that such Security has been duly authenticated and delivered hereunder
and is entitled to the benefits of this Indenture.

     (f) If all Securities of a series are not to be authenticated and issued at
one time, the Company shall not be required to deliver the Company Order, Board
Resolutions, Officers' Certificate and Opinion of Counsel (including any such
that would be otherwise required pursuant to Section 14.05 hereof) described in
Section 2.05(c) hereof at or prior to the authentication of each Security of
such series, if such items are delivered at or prior to the time of
authentication of the first Security of such series to be authenticated and
issued. If all of the Securities of a series are not authenticated and issued at
one time, for each issuance of Securities after the initial issuance of
Securities, the Company shall be required only to deliver to the Trustee the
Security and a written request (executed by one of the Chairman, the President,
any Vice President, the Treasurer, or an Assistant Treasurer, and the Secretary
or an Assistant Secretary of the Company) to the Trustee to authenticate such
Security and to deliver such

                                       10
<Page>

Security in accordance with the instructions specified by such request. Any such
request shall constitute a representation and warranty by the Company that the
statements made in the Officers' Certificate delivered to the Trustee prior to
the authentication and issuance of the first Security of such series are true
and correct on the date thereof as if made on and as of the date thereof.


     SECTION 2.06. EXCHANGE AND REGISTRATION OF TRANSFER OF SECURITIES.

     (a) Subject to Section 2.13 hereof, Securities may be exchanged for one or
more new Securities of any authorized denominations and of a like aggregate
principal amount, series and stated maturity and having the same terms and
Original Issue Date or Dates. Securities to be exchanged shall be surrendered at
any of the offices or agencies to be maintained pursuant to Section 5.02 hereof,
and the Trustee shall deliver in exchange therefor the Security or Securities
which the Security holder making the exchange shall be entitled to receive.

     (b) The Trustee shall keep, at one of said offices or agencies, a register
or registers in which, subject to such reasonable regulations as it may
prescribe, the Trustee shall register or cause to be registered Securities and
shall register or cause to be registered the transfer of Securities as in this
Article Two provided. Such register shall be in written form or in any other
form capable of being converted into written form within a reasonable time. At
all reasonable times, such register shall be open for inspection by the Company.
Upon due presentment for registration of transfer of any Security at any such
office or agency, the Company shall execute and the Trustee shall register,
authenticate and deliver in the name of the transferee or transferees one or
more new Securities of any authorized denominations and of a like aggregate
principal amount, series and stated maturity and having the same terms and
Original Issue Date or Dates.

     (c) All Securities presented for registration of transfer or for exchange,
redemption or payment shall be duly endorsed by, or be accompanied by a written
instrument or instruments of transfer in form satisfactory to the Company and
the Trustee and duly executed by the Holder or the attorney in fact of such
Holder duly authorized in writing.

     (d) No service charge shall be made for any exchange or registration of
transfer of Securities, but the Company may require payment of a sum sufficient
to cover any tax or other governmental charge that may be imposed in connection
therewith.

     (e) The Trustee shall not be required to exchange or register a transfer of
any Securities selected, called or being called for redemption (including
Securities, if any, redeemable at the option of the Holder provided such
Securities are then redeemable at such Holder's option) except, in the case of
any Security to be redeemed in part, the portion thereof not to be so redeemed.

     (f) If the principal amount, and applicable premium, of part, but not all
of a Global Security is paid, then upon surrender to the Trustee of such Global
Security, the Company shall execute, and the Trustee shall authenticate, deliver
and register, a Global Security in an

                                       11
<Page>

authorized denomination in aggregate principal amount equal to, and having the
same terms, Original Issue Date or Dates and series as, the unpaid portion of
such Global Security.

     SECTION 2.07. MUTILATED, DESTROYED, LOST OR STOLEN SECURITIES.

     (a) If any temporary or definitive Security shall become mutilated or be
destroyed, lost or stolen, the Company shall execute, and upon its request the
Trustee shall authenticate and deliver, a new Security of like form and
principal amount and having the same terms and Original Issue Date or Dates and
bearing a number not contemporaneously outstanding, in exchange and substitution
for the mutilated Security, or in lieu of and in substitution for the Security
so destroyed, lost or stolen. In every case the applicant for a substituted
Security shall furnish to the Company, the Trustee and any paying agent or
Authenticating Agent 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 of
a Security, the applicant shall also furnish to the Company and to the Trustee
evidence to their satisfaction of the destruction, loss or theft of such
Security and of the ownership thereof.

     (b) The Trustee shall authenticate any such substituted Security and
deliver the same upon the written request or authorization of any officer of the
Company. Upon the issuance of any substituted Security, the Company may require
the payment of a sum sufficient to cover any tax or other governmental charge
that may be imposed in relation thereto and any other expenses connected
therewith. If any Security which has matured, is about to mature, has been
redeemed or called for redemption shall become mutilated or be destroyed, lost
or stolen, the Company may, instead of issuing a substituted Security, pay or
authorize the payment of the same (without surrender thereof except in the case
of a mutilated Security) if the applicant for such payment shall furnish to the
Company, the Trustee and any paying agent or Authenticating Agent such security
or indemnity as may be required by them to save each of them harmless and, in
case of destruction, loss or theft, evidence satisfactory to the Company and the
Trustee of the destruction, loss or theft of such Security and of the ownership
thereof.

     (c) Every substituted Security issued pursuant to this Section 2.07 by
virtue of the fact that any Security is mutilated, destroyed, lost or stolen
shall constitute an additional contractual obligation of the Company, whether or
not such destroyed, lost or stolen Security shall be found at any time, and
shall be entitled to all the benefits of this Indenture equally and
proportionately with any and all other Securities duly issued hereunder. All
Securities shall be held and owned upon the express condition that, to the
extent permitted by law, the foregoing provisions are exclusive with respect to
the replacement or payment of mutilated, destroyed, lost or stolen Securities
and shall preclude any and all other rights or remedies notwithstanding any law
or statute existing or hereafter enacted to the contrary with respect to the
replacement or payment of negotiable instruments or other securities without
their surrender.

     SECTION 2.08. TEMPORARY SECURITIES. Pending the preparation of definitive
Securities, the Company may execute and the Trustee shall authenticate and
deliver temporary Securities (printed, lithographed or otherwise reproduced).
Temporary Securities shall be issuable in any authorized denomination and
substantially in the form of the definitive Securities but with such omissions,
insertions and variations as may be appropriate for temporary Securities, all as
may be determined by the Company. Every such temporary Security shall be

                                       12
<Page>

authenticated by the Trustee upon the same conditions and in substantially the
same manner, and with the same effect, as the definitive Securities. Without
unreasonable delay the Company shall execute and shall deliver to the Trustee
definitive Securities and thereupon any or all temporary Securities shall be
surrendered in exchange therefor at the corporate trust office of the Trustee,
and the Trustee shall authenticate, deliver and register in exchange for such
temporary Securities an equal aggregate principal amount of definitive
Securities. Such exchange shall be made by the Company at its own expense and
without any charge therefor to the Security holders. Until so exchanged, the
temporary Securities shall in all respects be entitled to the same benefits
under this Indenture as definitive Securities authenticated and delivered
hereunder.

     SECTION 2.09. CANCELLATION OF SECURITIES PAID, ETC. All Securities
surrendered for the purpose of payment, redemption, exchange or registration of
transfer shall be surrendered to the Trustee for cancellation and promptly
cancelled by it and no Securities shall be issued in lieu thereof except as
expressly permitted by this Indenture. The Company's acquisition of any
Securities shall operate as a redemption or satisfaction of the indebtedness
represented by such Securities and such Securities shall be surrendered by the
Company to and cancelled by the Trustee.

     SECTION 2.10. INTEREST RIGHTS PRESERVED. Each Security delivered under this
Indenture upon transfer of or in exchange for or in lieu of any other Security
shall carry all the rights to interest accrued and unpaid, and to accrue, which
were carried by such other Security, and each such Security shall be so dated
that neither gain nor loss of interest shall result from such transfer, exchange
or substitution.

     SECTION 2.11. SPECIAL RECORD DATE. If and to the extent that the Company
fails to make timely payment or provision for timely payment of interest on any
series of Securities (other than on an Interest Payment Date that is a maturity
date), that interest shall cease to be payable to the Persons who were the
Security holders of such series at the applicable Regular Record Date. In that
event, when moneys become available for payment of the interest, the Trustee
shall (a) establish a date of payment of such interest and a Special Record Date
for the payment of that interest, which Special Record Date shall be not more
than 15 or fewer than 10 days prior to the date of the proposed payment and (b)
mail notice of the date of payment and of the Special Record Date not fewer than
10 days preceding the Special Record Date to each Security holder of such series
at the close of business on the 15th day preceding the mailing at the address of
such Security holder, as it appeared on the register for the Securities. On the
day so established by the Trustee the interest shall be payable to the Holders
of the applicable Securities at the close of business on the Special Record
Date.

     SECTION 2.12. PAYMENT OF SECURITIES. Payment of the principal, interest and
premium on all Securities shall be payable as follows:

     (a) On or before 9:30 a.m., New York City time, of the day on which payment
of principal, interest and premium is due on any Global Security pursuant to the
terms thereof, the Company shall deliver to the Trustee funds available on such
date sufficient to make such payment, by wire transfer of immediately available
funds or by instructing the Trustee to withdraw sufficient funds from an account
maintained by the Company with the Trustee or such other method as is acceptable
to the Trustee and the Depositary. On or before 10:00 a.m., New York City time,
or such other time as shall be agreed upon between the Trustee and the
Depositary, of the day on which any payment of interest is due on any Global
Security (other than at maturity), the Trustee shall pay to the Depositary such
interest in same day funds. On or before 10:00 a.m., New

                                       13
<Page>

York City time or such other time as shall be agreed upon between the Trustee
and the Depositary, of the day on which principal, interest payable at maturity
and premium, if any, is due on any Global Security, the Trustee shall deposit
with the Depositary the amount equal to the principal, interest payable at
maturity and premium, if any, by wire transfer into the account specified by the
Depositary. As a condition to the payment, at maturity or upon redemption, of
any part of the principal or interest on and applicable premium of any Global
Security, the Depositary shall surrender, or cause to be surrendered, such
Global Security to the Trustee, whereupon a new Global Security shall be issued
to the Depositary pursuant to Section 2.06(f) hereof.

     (b) With respect to any Security that is not a Global Security, principal,
applicable premium and interest due at the maturity of the Security shall be
payable in immediately available funds when due upon presentation and surrender
of such Security at the corporate trust office of the Trustee or at the
authorized office of any paying agent. Interest on any Security that is not a
Global Security (other than interest payable at maturity) shall be paid to the
Holder thereof as its name appears on the register by check payable in
clearinghouse funds; provided that if the Trustee receives a written request
from any Holder of Securities, the aggregate principal amount of which having
the same Interest Payment Date equals or exceeds $10,000,000, on or before the
applicable Regular Record Date for such Interest Payment Date, interest shall be
paid by wire transfer of immediately available funds to a bank within the
continental United States designated by such Holder in its request or by direct
deposit into the account of such Holder designated by such Holder in its request
if such account is maintained with the Trustee or any paying agent.

     SECTION 2.13. SECURITIES ISSUABLE IN THE FORM OF A GLOBAL SECURITY.

     (a) If the Company shall establish pursuant to Section 2.05 hereof that the
Securities of a particular series are to be issued in whole or in part in the
form of one or more Global Securities, then the Company shall execute and the
Trustee shall, in accordance with Section 2.05 hereof and the Company Order
delivered to the Trustee thereunder, authenticate and deliver such Global
Security or Securities, which (i) shall represent, shall be denominated in an
amount equal to the aggregate principal amount of, and shall have the same terms
as, the outstanding Securities of such series to be represented by such Global
Security or Securities, (ii) shall be registered in the name of the Depositary
or its nominee, (iii) shall be delivered by the Trustee to the Depositary or
pursuant to the Depositary's instruction and (iv) shall bear a legend
substantially to the following effect: "This Security is a Global Security
registered in the name of the Depositary (referred to herein) or a nominee
thereof and, unless and until it is exchanged in whole or in part for the
individual Securities represented hereby, this Global Security may not be
transferred except as a whole by the Depositary to a nominee of the Depositary
or by a nominee of the Depositary to the Depositary or another nominee of the
Depositary or by the Depositary or any such nominee to a successor Depositary or
a nominee of such successor Depositary. Unless this Global Security is presented
by an authorized representative of The Depository Trust Company (55 Water
Street, New York, New York), to the trustee for registration of transfer,
exchange or payment, and any certificate issued is registered in the name of
Cede & Co. or such other name as requested by an

                                       14
<Page>

authorized representative of The Depository Trust Company and any payment is
made to Cede & Co., any transfer, pledge or other use hereof for value or
otherwise by or to any person is wrongful since the registered owner hereof,
Cede & Co., has an interest herein" or such other legend as may be required by
the rules and regulations of the Depositary.

     (b) Notwithstanding any other provision of Section 2.06 hereof or of this
Section 2.13, unless the terms of a Global Security expressly permit such Global
Security to be exchanged in whole or in part for individual Securities, a Global
Security may be transferred, in whole but not in part, only as described in the
legend thereto.

     (c) (i) If at any time the Depositary for a Global Security notifies the
Company that it is unwilling or unable to continue as Depositary for such Global
Security or if at any time the Depositary for the Global Security shall no
longer be eligible or in good standing under the Securities Exchange Act of
1934, as amended, or other applicable statute or regulation, the Company shall
appoint a successor Depositary with respect to such Global Security. If a
successor Depositary for such Global Security is not appointed by the Company
within 90 days after the Company receives such notice or becomes aware of such
ineligibility, the Company's election pursuant to Section 2.05(c)(vi) hereof
shall no longer be effective with respect to the series of Securities evidenced
by such Global Security and the Company shall execute, and the Trustee, upon
receipt of a Company Order for the authentication and delivery of individual
Securities of such series in exchange for such Global Security, shall
authenticate and deliver, individual Securities of such series of like tenor and
terms in definitive form in an aggregate principal amount equal to the principal
amount of the Global Security in exchange for such Global Security. The Trustee
shall not be charged with knowledge or notice of the ineligibility of a
Depositary unless a responsible officer assigned to and working in its corporate
trustee administration department shall have actual knowledge thereof.

     (ii) The Company may at any time and in its sole discretion determine that
all outstanding (but not less than all) Securities of a series issued or
issuable in the form of one or more Global Securities shall no longer be
represented by such Global Security or Securities. In such event the Company
shall execute, and the Trustee, upon receipt of a Company Order for the
authentication and delivery of individual Securities in exchange for such Global
Security, shall authenticate and deliver individual Securities of like tenor and
terms in definitive form in an aggregate principal amount equal to the principal
amount of such Global Security or Securities in exchange for such Global
Security or Securities.

     (iii) In any exchange provided for in any of the preceding two paragraphs,
the Company will execute and the Trustee will authenticate and deliver
individual Securities in definitive registered form in authorized denominations.
Upon the exchange of a Global Security for individual Securities, such Global
Security shall be cancelled by the Trustee. Securities issued in exchange for a
Global Security pursuant to this Section shall be registered in such names and
in such authorized denominations as the Depositary for such Global Security,
pursuant to instructions from its direct or indirect participants or otherwise,
shall instruct the Trustee. The Trustee shall deliver such Securities to the
Depositary for delivery to the persons in whose names such Securities are so
registered, or if the Depositary shall refuse or be unable to deliver such
Securities, the Trustee shall deliver such Securities to the persons in whose
names such Securities are registered, unless otherwise agreed upon between the
Trustee and the Company, in

                                       15
<Page>

which event the Company shall cause the Securities to be delivered to the
persons in whose names such Securities are registered.

     (d) Neither the Company, the Trustee, any Authenticating Agent nor any
paying agent shall have any responsibility or liability for any aspect of the
records relating to, or payments made on account of, beneficial ownership
interests of a Global Security or for maintaining, supervising or reviewing any
records relating to such beneficial ownership interest.

     (e) Pursuant to the provisions of this subsection, at the option of the
Trustee and upon 30 days' written notice to the Depositary but not prior to the
first Interest Payment Date of the respective Global Securities, the Depositary
shall be required to surrender any two or more Global Securities which have
identical terms, including, without limitation, identical maturities, interest
rates and redemption provisions (but which may have differing Original Issue
Dates) to the Trustee, and the Company shall execute and the Trustee shall
authenticate and deliver to, or at the direction of, the Depositary a Global
Security in principal amount equal to the aggregate principal amount of, and
with all terms identical to, the Global Securities surrendered thereto and that
shall indicate each applicable Original Issue Date and the principal amount
applicable to each such Original Issue Date. The exchange contemplated in this
subsection shall be consummated at least 30 days prior to any Interest Payment
Date applicable to any of the Global Securities surrendered to the Trustee. Upon
any exchange of any Global Security with two or more Original Issue Dates,
whether pursuant to this Section or pursuant to Section 2.06 or Section 3.03
hereof, the aggregate principal amount of the Securities with a particular
Original Issue Date shall be the same before and after such exchange, after
giving effect to any retirement of Securities and the Original Issue Dates
applicable to such Securities occurring in connection with such exchange.

                                 ARTICLE THREE.

                            REDEMPTION OF SECURITIES

     SECTION 3.01. APPLICABILITY OF ARTICLE. Such of the Securities as are, by
their terms, redeemable prior to their stated maturity date at the option of the
Company, may be redeemed by the Company at such times, in such amounts and at
such prices as may be specified therein and in accordance with the provisions of
this Article Three.

     SECTION 3.02. NOTICE OF REDEMPTION; SELECTION OF SECURITIES.

     (a) The election of the Company to redeem any Securities shall be evidenced
by a Board Resolution which shall be given with notice of redemption to the
Trustee at least 45 days (or such shorter period acceptable to the Trustee in
its sole discretion) prior to the redemption date specified in such notice.

     (b) Notice of redemption to each Holder of Securities to be redeemed as a
whole or in part shall be given by the Trustee, in the manner provided in
Section 14.10 hereof, no less than 30 or more than 60 days prior to the date
fixed for redemption. Any notice which is given in the manner herein provided
shall be conclusively presumed to have been duly given, whether or not the
Security holder receives the notice. In any case, failure duly to give such
notice, or any

                                       16
<Page>

defect in such notice, to the Holder of any Security designated for redemption
as a whole or in part shall not affect the validity of the proceedings for the
redemption of any other Security.

     (c) Each such notice shall specify the date fixed for redemption, the
places of redemption and the redemption price at which such Securities are to be
redeemed, and shall state that payment of the redemption price of such
Securities or portion thereof to be redeemed will be made upon surrender of such
Securities at such places of redemption, that interest accrued to the date fixed
for redemption will be paid as specified in such notice, and that from and after
such date interest thereon shall cease to accrue. If less than all of a series
of Securities having the same terms are to be redeemed, the notice shall specify
the Securities or portions thereof to be redeemed. If any Security is to be
redeemed in part only, the notice which relates to such Security shall state the
portion of the principal amount thereof to be redeemed, and shall state that,
upon surrender of such Security, a new Security or Securities having the same
terms in aggregate principal amount equal to the unredeemed portion thereof will
be issued.

     (d) Unless otherwise provided by a supplemental indenture or Company Order
under Section 2.05 hereof, if less than all of a series of Securities is to be
redeemed, the Trustee shall select in such manner as it shall deem appropriate
and fair in its discretion the particular Securities to be redeemed in whole or
in part and shall thereafter promptly notify the Company in writing of the
Securities so to be redeemed. If less than all of a series of Securities
represented by a Global Security is to be redeemed, the particular Securities or
portions thereof of such series to be redeemed shall be selected by the
Depositary for such series of Securities in such manner as the Depositary shall
determine. Securities shall be redeemed only in denominations of $1,000,
provided that any remaining principal amount of a Security redeemed in part
shall be a denomination authorized under this Indenture.

     (e) If at the time of the mailing of any notice of redemption the Company
shall not have irrevocably directed the Trustee to apply funds deposited with
the Trustee or held by it and available to be used for the redemption of
Securities to redeem all the Securities called for redemption, such notice, at
the election of the Company, may state that it is subject to the receipt of the
redemption moneys by the Trustee before the date fixed for redemption and that
such notice shall be of no effect unless such moneys are so received before such
date.

     SECTION 3.03. PAYMENT OF SECURITIES ON REDEMPTION; DEPOSIT OF REDEMPTION
PRICE.

     (a) If notice of redemption for any Securities shall have been given as
provided in Section 3.02 hereof and such notice shall not contain the language
permitted at the Company's option under Section 3.02(e) hereof, such Securities
or portions of Securities called for redemption shall become due and payable on
the date and at the places stated in such notice at the applicable redemption
price, together with interest accrued to the date fixed for redemption of such
Securities. Interest on the Securities or portions thereof so called for
redemption shall cease to accrue and such Securities or portions thereof shall
be deemed not to be entitled to any benefit under this Indenture except to
receive payment of the redemption price together with interest accrued thereon
to the date fixed for redemption. Upon presentation and surrender of such
Securities at such a place of payment in such notice specified, such Securities
or the

                                       17
<Page>

specified portions thereof shall be paid and redeemed at the applicable
redemption price, together with interest accrued thereon to the date fixed for
redemption.

     (b) If notice of redemption shall have been given as provided in Section
3.02 hereof and such notice shall contain the language permitted at the
Company's option under Section 3.02(e) hereof, such Securities or portions of
Securities called for redemption shall become due and payable on the date and at
the places stated in such notice at the applicable redemption price, together
with interest accrued to the date fixed for redemption of such Securities, and
interest on the Securities or portions thereof so called for redemption shall
cease to accrue and such Securities or portions thereof shall be deemed not to
be entitled to any benefit under this Indenture except to receive payment of the
redemption price together with interest accrued thereon to the date fixed for
redemption; provided that, in each case, the Company shall have deposited with
the Trustee or a paying agent on or prior to such redemption date an amount
sufficient to pay the redemption price together with interest accrued to the
date fixed for redemption. Upon the Company making such deposit and, upon
presentation and surrender of such Securities at such a place of payment in such
notice specified, such Securities or the specified portions thereof shall be
paid and redeemed at the applicable redemption price, together with interest
accrued thereon to the date fixed for redemption. If the Company shall not make
such deposit on or prior to the redemption date, the notice of redemption shall
be of no force and effect and the principal on such Securities or specified
portions thereof shall continue to bear interest as if the notice of redemption
had not been given.

     (c) No notice of redemption of Securities shall be mailed during the
continuance of any Event of Default, except (1) that, when notice of redemption
of any Securities has been mailed, the Company shall redeem such Securities but
only if funds sufficient for that purpose have prior to the occurrence of such
Event of Default been deposited with the Trustee or a paying agent for such
purpose, and (2) that notices of redemption of all outstanding Securities may be
given during the continuance of an Event of Default.

     (d) Upon surrender of any Security redeemed in part only, the Company shall
execute, and the Trustee shall authenticate, deliver and register, a new
Security or Securities of authorized denominations in aggregate principal amount
equal to, and having the same terms, Original Issue Date or Dates and series as,
the unredeemed portion of the Security so surrendered.

                                  ARTICLE FOUR.

                  SATISFACTION AND DISCHARGE; UNCLAIMED MONEYS

     SECTION 4.01. SATISFACTION AND DISCHARGE.

     (a) If at any time:

          (1) the Company shall have paid or caused to be paid the principal of
     and premium, if any, and interest on all the outstanding Securities, as and
     when the same shall have become due and payable,

          (2) the Company shall have delivered to the Trustee for cancellation
     all outstanding Securities, or

                                       18
<Page>

          (3) the Company shall have irrevocably deposited or caused to be
     irrevocably deposited with the Trustee as trust funds the entire amount in
     (A) cash, (B) U.S. Government Obligations maturing as to principal and
     interest in such amounts and at such times as will insure the availability
     of cash, or (C) a combination of cash and U.S. Government Obligations, in
     any case sufficient, without reinvestment, as certified by an independent
     public accounting firm of national reputation in a written certification
     delivered to the Trustee, to pay at maturity or the applicable redemption
     date (provided that notice of redemption shall have been duly given or
     irrevocable provision satisfactory to the Trustee shall have been duly made
     for the giving of any notice of redemption) all outstanding Securities,
     including principal and any premium and interest due or to become due to
     such date of maturity, as the case may be and, unless all outstanding
     Securities are to be due within 90 days of such deposit by redemption or
     otherwise, shall also deliver to the Trustee an Opinion of Independent
     Counsel to the effect that the Company has received from, or there has been
     published by, the Internal Revenue Service a ruling or similar
     pronouncement by the Internal Revenue Service, or that there has been a
     change of law, in either case to the effect that the Holders of the
     Securities will not recognize income, gain or loss for federal income tax
     purposes as a result of such defeasance or discharge of the Indenture,

other sums payable hereunder by the Company, then this Indenture shall cease to
be of further effect (except as to (i) rights of registration of transfer and
exchange of Securities, (ii) substitution of mutilated, defaced, destroyed, lost
or stolen Securities, (iii) rights of Security holders to receive payments of
principal thereof, and any premium and interest thereon, upon the original

payable to all or any of them, (vi) the obligations and rights of the Trustee
and the Company under Section 4.04 hereof, and (vii) the duties of the Trustee
with respect to any of the foregoing), and the Company shall be deemed to have
paid and discharged the entire indebtedness represented by, and its obligations
under, the Securities, and the Trustee, on demand of the Company and at the cost
and expense of the Company, shall execute proper instruments acknowledging such
satisfaction of and discharging this Indenture and the Trustee shall at the
request of the Company return to the Company all property and money held by it
under this Indenture and determined by it from time to time in accordance with
the certification pursuant to this Section 4.01(a)(3) to be in excess of the
amount required to be held under this Section.

     If the Securities are deemed to be paid and discharged pursuant to Section
4.01(a)(3) hereof, within 15 days after those Securities are so deemed to be
paid and discharged, the Trustee shall cause a written notice to be given to
each Holder in the manner provided by Section 14.10 hereof. The notice shall:

          (i) state that the Securities are deemed to be paid and discharged;

          (ii) set forth a description of any U.S. Government Obligations and
     cash held by the Trustee as described above;

                                       19
<Page>

          (iii) if any Securities will be called for redemption, specify the
     date or dates on which those Securities are to be called for redemption.

Notwithstanding the satisfaction and discharge of this Indenture, the
obligations of the Company to the Trustee under Section 8.06 hereof, shall
survive.

     (b) If the Company shall have paid or caused to be paid the principal of
and premium, if any, and interest on any Security, as and when the same shall
have become due and payable or the Company shall have delivered to the Trustee
for cancellation any outstanding Security, such Security shall cease to be
entitled to any lien, benefit or security under this Indenture.

     SECTION 4.02. DEPOSITED MONEYS TO BE HELD IN TRUST BY TRUSTEE. All moneys
and U.S. Government Obligations deposited with the Trustee pursuant to Section
4.01 hereof shall be held in trust and applied by it to the payment, either
directly or through any paying agent (including the Company if acting as its own
paying agent), to the Holders of the particular Securities for the payment or
redemption of which such moneys and U.S. Government Obligations have been
deposited with the Trustee of all sums due and to become due thereon for
principal and premium, if any, and interest.

     SECTION 4.03. PAYING AGENT TO REPAY MONEYS HELD. Upon the satisfaction and
discharge of this Indenture all moneys then held by any paying agent for the
Securities (other than the Trustee) shall, upon written demand by an Authorized
Agent, be repaid to the Company or paid to the Trustee, and thereupon such
paying agent shall be released from all further liability with respect to such
moneys.

     SECTION 4.04. RETURN OF UNCLAIMED MONEYS. Any moneys deposited with or paid
to the Trustee for payment of the principal of or any premium or interest on any
Securities and not applied but remaining unclaimed by the Holders of such
Securities for two years after the date upon which the principal of or any
premium or interest on such Securities, as the case may be, shall have become
due and payable, shall be repaid to the Company by the Trustee on written demand
by an Authorized Agent, and all liability of the Trustee shall thereupon cease;
and any Holder of any of such Securities shall thereafter look only to the
Company for any payment which such Holder may be entitled to collect.

                                  ARTICLE FIVE.

                       PARTICULAR COVENANTS OF THE COMPANY

     SECTION 5.01. PAYMENT OF PRINCIPAL, PREMIUM AND INTEREST. The Company

will duly and punctually pay or cause to be paid the principal of and any
premium and interest on each of the Securities at the places, at the respective

     SECTION 5.02. OFFICE FOR NOTICES AND PAYMENTS, ETC. So long as any of the
Securities remain outstanding, the Company at its option may cause to be
maintained in the Borough of Manhattan, the City and State of New York, or
elsewhere, an office or agency where the Securities may be presented for
registration of transfer and for exchange as in this Indenture

                                       20
<Page>

provided, and where, at any time when the Company is obligated to make a payment
of principal and premium upon Securities, the Securities may be surrendered for
payment, and may maintain at any such office or agency and at its principal
office an office or agency where notices and demands to or upon the Company in
respect of the Securities or of this Indenture may be served. The designation of
any such office or agency shall be made by Company Order pursuant to Section
2.05 hereof or at any subsequent time pursuant to this Section 5.02 hereof. The
Company will give to the Trustee written notice of the location of each such
office or agency and of any change of location thereof. If the Company shall
fail to give such notice of the location or of any change in the location of any
such office or agency, presentations may be made and notices and demands may be
served at the corporate trust office of the Trustee.

     SECTION 5.03. APPOINTMENTS TO FILL VACANCIES IN TRUSTEE'S OFFICE. The
Company, whenever necessary to avoid or fill a vacancy in the office of Trustee,
will appoint, in the manner provided in Section 8.11 hereof, a Trustee, so that

     SECTION 5.04. PROVISION AS TO PAYING AGENT. The Trustee shall be the paying
agent for the Securities and, at the option of the Company, the Company may
appoint additional paying agents (including without limitation itself). Whenever
the Company shall appoint an additional paying agent, it shall cause such paying
agent to execute and deliver to the Trustee an instrument in which such agent
shall agree with the Trustee, subject to this Section 5.04:

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

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

          (3) that it will at any time during the continuance of any such
     failure, upon the written request of the Trustee, forthwith pay to the
     Trustee all sums so held in trust by such paying agent.

     If the Company shall act as its own paying agent with respect to any
Securities, it will, on or before each due date of the principal of and any
premium or interest on such Securities, set aside, segregate and hold in trust
for the benefit of the Holders of such Securities a sum sufficient to pay such
principal and any premium or interest so becoming due and will notify the
Trustee of any failure by it to take such action and of any failure by the
Company (or by any other obligor on such Securities) to make any payment of the
principal of and any premium or interest on such Securities when the same shall
become due and payable.

     Whenever the Company shall have one or more paying agents, it will, on or
prior to each due date of the principal of (and premium, if any) or interest, if
any, on any Securities, deposit with such paying agent a sum sufficient to pay
the principal (and premium, if any) or interest, if any, so becoming due, such
sum to be held in trust for the benefit of the Persons entitled to such

                                       21
<Page>

principal, premium or interest, if any, and (unless such paying agent is the
Trustee) the Company shall promptly notify the Trustee of any failure on its
part to so act.

     Anything in this Section 5.04 to the contrary notwithstanding, the Company
may, at any time, for the purpose of obtaining a satisfaction and discharge of
this Indenture, or for any other reason, pay or cause to be paid to the Trustee
all sums held in trust by it or any paying agent hereunder, as required by this
Section 5.04, such sums to be held by the Trustee upon the trusts herein
contained.

     Anything in this Section 5.04 to the contrary notwithstanding, the
agreement to hold sums in trust as provided in this Section 5.04 is subject to
Sections 4.03 and 4.04 hereof.

     SECTION 5.05. CERTIFICATES AND NOTICE TO TRUSTEE. The Company shall, on or
before May 1 of each year, beginning in 2002, deliver to the Trustee a
certificate from its principal executive officer, principal financial officer or
principal accounting officer covering the preceding calendar year and stating
whether or not, to the knowledge of such party, the Company has complied with
all conditions and covenants under this Indenture, and, if not, describing in
reasonable detail any failure by the Company to comply with any such conditions
or covenants. For purposes of this Section, compliance shall be determined
without regard to any period of grace or requirement of notice provided under
this Indenture.

                                  ARTICLE SIX.

        SECURITY HOLDER LISTS AND REPORTS BY THE COMPANY AND THE TRUSTEE

     SECTION 6.01. SECURITY HOLDER LISTS.

     (a) The Company shall furnish or cause to be furnished to the Trustee
semiannually, not later than 15 days after each Regular Record Date for each
Interest Payment Date that is not a maturity date and at such other times as
such Trustee may request in writing, within 30 days after receipt by the Company
of any such request, a list in such form as the Trustee may reasonably require
containing all the information in the possession or control of the Company, or
any paying agents other than the Trustee, as to the names and addresses of the
Holders of Securities, obtained since the date as of which the next previous
list, if any, was furnished. Any such list may be dated as of a date not more
than 15 days prior to the time such information is furnished or caused to be
furnished and need not include information received after such date; provided
that as long as the Trustee is the registrar for the Securities, no such list
shall be required to be furnished. The Trustee shall preserve any list provided
to it pursuant to this Section until such time as the Company or any paying
agent, as applicable, shall provide it with a more recent list.

     (b) Within five business days after the receipt by the Trustee of a written
application by any three or more Holders stating that the applicants desire to
communicate with other Holders with respect to their rights under the Indenture
or under the Securities, and accompanied by a copy of the form of proxy or other
communication which such applicants propose to transmit, and by reasonable proof
that each such applicant has owned a Security for a period of at least six
months preceding the date of such application, the Trustee shall, at its
election, either:

                                       22
<Page>

          (i) afford to such applicants access to all information furnished to
     or received by the Trustee pursuant to Section 6.01(a) hereof or, if
     applicable, in its capacity as registrar to the Securities; or

          (ii) inform such applicants as to the approximate number of Holders
     according to the most recent information furnished to or received by the
     Trustee under Section 6.01(a) hereof or if applicable in its capacity as
     registrar for the Securities, and as to the approximate cost of mailing to
     such Holders the form of proxy or other communication, if any, specified in
     such application.

     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 Securities 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 such mailing, unless
within five days after such tender the Trustee shall mail to such applicants and
file with 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 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 Holders 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.

     (c) Every Holder of a Security, 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 Authenticating Agent shall be held accountable by
reason of the disclosure of any such information as to the names and addresses
of the Holders in accordance with 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
this Section.

     SECTION 6.02. SECURITIES AND EXCHANGE COMMISSION REPORTS. The Company
shall:

     (a) 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 Securities Exchange Act of 1934;
or, if the Company is not required to file information, documents or reports
pursuant to either of said Sections, then it will file with the Trustee and the
Commission, in accordance with 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

                                       23
<Page>

the Securities Exchange Act of 1934 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) file with the Trustee and the Commission, in accordance with 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 conditions and covenants of this Indenture as may be required from time
to time by such rules and regulations, including, in the case of annual reports,
if required by such rules and regulations, certificates or opinions of
independent public accountants, conforming to the requirements of Section 14.05,
as to compliance with conditions or covenants, compliance with which is subject
to verification by accountants; and

     (c) transmit by mail to all Holders, as their names and addresses appear in
the register, within 30 days after the filing thereof with the Trustee, such
summaries of any information, documents and reports required to be filed by the
Company pursuant to paragraphs (a) and (b) of this Section as may be required by
rules and regulations prescribed from time to time by the Commission.

     SECTION 6.03. REPORTS BY THE TRUSTEE.

     (a) Within 60 days after July 15 of each year, beginning with the July 15
after the first issuance of Securities hereunder, the Trustee shall transmit by
mail a brief report dated as of such date that complies with Section 313(a) of
the TIA (to the extent required by such Section).

     (b) The Trustee shall from time to time transmit by mail brief reports that
comply, both in content and date of delivery, with Section 313(b) of the TIA (to
the extent required by such Section).

     (c) A copy of each such report filed pursuant to this section shall, at the
time of such transmission to such Holders, be filed by the Trustee with each
stock exchange upon which any Securities are listed and also with the
Commission. The Company will notify the Trustee promptly upon the listing of
such Securities on any stock exchange.

     (d) Reports pursuant to this Section shall be transmitted

          (1) by mail to all Holders of Securities, as their names and addresses
     appear in the register for the Securities;

          (2) by mail to such Holders of Securities as have, within the two
     years preceding such transmission, filed their names and addresses with the
     Trustee for such purpose;

     and (c) hereof, to all Holders of Securities whose names and addresses have
     been furnished to or received by the Trustee pursuant to Section 6.01
     hereof, and

          (4) at the time such report is transmitted to the Holders of the
     Securities, to each exchange on which Securities are listed and also with

                                 ARTICLE SEVEN.

                           REMEDIES OF THE TRUSTEE AND
                      SECURITY HOLDERS ON EVENTS OF DEFAULT

     SECTION 7.01. EVENTS OF DEFAULT.

     (a) If one or more of the following Events of Default shall have occurred
and be continuing:

          (1) default in the payment of any installment of interest upon any of
     the Securities as and when the same shall become due and payable, and
     continuance of such default for a period of 30 days;

          (2) default in the payment of the principal of or any premium on any
     of the Securities as and when the same shall become due and payable and
     continuance of such default for five days;

          (3) failure on the part of the Company duly to observe or perform any
     other of the covenants or agreements on the part of the Company contained
     in the Securities or in this Indenture for a period of 90 days after the
     date on which written notice of such failure, requiring the same to be
     remedied and stating that such notice is a "Notice of Default" hereunder,
     shall have been given to the Company by the Trustee by registered mail, or
     to the Company and the Trustee by the Holders of at least 25% in aggregate
     principal amount of the Securities at the time outstanding;

          (4) the entry of a decree or order by a court having jurisdiction over
     the Company for relief in respect of the Company under Title 11 of the
     United States Code, as now constituted or hereafter amended, or any other
     applicable federal or state bankruptcy, insolvency or other similar law, or
     appointing a receiver, liquidator, assignee, trustee, custodian,
     sequestrator or similar official of the Company or of any substantial part
     of its property, or ordering the winding-up or liquidation of its affairs,
     and the continuance of any such decree or order unstayed and in effect for
     a period of 60 consecutive days; or

          (5) the filing by the Company with respect to itself or its property
     of a petition or answer or consent seeking relief under Title 11 of the
     United States Code, as now constituted or hereafter amended, or any other
     applicable federal or state bankruptcy, insolvency or other similar law, or
     the consent by it to the institution of proceedings thereunder or to the
     filing of any such petition or to the appointment of or taking possession
     by a receiver, liquidator, assignee, trustee, custodian, sequestrator or
     other similar official of the Company or of any substantial part of its
     property, or the failure of the Company generally to pay its debts as such
     debts become due, or the taking of corporate action by the Company to
     effectuate any such action;

then and in each and every such case, unless the principal of all of the
Securities shall have already become due and payable, either the Trustee or the
Holders of a majority in aggregate principal amount of the Securities then
outstanding, by notice in writing to the Company (and to the Trustee if given by
Security holders), may declare the principal of all the Securities to be due

                                       25
<Page>

and payable immediately and upon any such declaration the same shall become and
shall be immediately due and payable, anything in this Indenture or in the
Securities contained to the contrary notwithstanding. This provision, however,
is subject to the condition that if, at any time after the principal of the
Securities 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 of the
Securities and the principal of and any premium on any and all Securities which
shall have become due otherwise than by acceleration (with interest on overdue
installments of interest, to the extent that payment of such interest is
enforceable under applicable law, and on such principal and applicable premium
at the rate borne by the Securities to the date of such payment or deposit) and
all sums paid or advanced by the Trustee hereunder, the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel, and
any other amounts due the Trustee under Section 8.06 hereof; and any and all
defaults under this Indenture, other than the non-payment of principal of and
accrued interest on Securities which shall have become due solely by
acceleration of maturity, shall have been cured or waived, then and in every
such case such payment or deposit shall cause an automatic waiver of the Event
of Default and its consequences and shall cause an automatic rescission and
annulment of the acceleration of the Securities; but no such waiver or
rescission and annulment shall extend to or shall affect any subsequent default,
or shall impair any right consequent thereon.

     (b) If the Trustee shall have proceeded to enforce any right 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 several positions and rights
hereunder, and all rights, remedies and powers of the Company and the Trustee
shall continue as though no such proceeding had been taken.

     SECTION 7.02. PAYMENT OF SECURITIES ON DEFAULT; SUIT THEREFOR.

     (a) The Company covenants that in case of:

          (1) default in the payment of any installment of interest upon any of
     the Securities as and when the same shall become due and payable, and
     continuance of such default for a period of 30 days; or

          (2) default in the payment of the principal of or any premium on any
     of the Securities as and when the same shall have become due and payable
     whether at the stated maturity thereof, upon redemption thereof (provided
     that such redemption is not conditioned upon the deposit of sufficient
     moneys for such redemption), upon declaration of acceleration or otherwise.

then, upon demand of the Trustee, the Company shall pay to the Trustee, for the
benefit of the Holders of the Securities, the whole amount that then shall have
so become due and payable on all such Securities for principal and any premium
or interest, or both, as the case may be, with interest upon the overdue
principal and any premium and (to the extent that payment of such interest is
enforceable under applicable law) upon the overdue installments of interest at
the rate

                                       26
<Page>

borne by the Securities; and, in addition thereto, such further amounts as shall
be sufficient to cover the costs and expenses of collection, including
reasonable compensation to the Trustee, its agents, attorneys and counsel, any
expenses or liabilities incurred by the Trustee hereunder other than through its
negligence or bad faith, and any other amounts due the Trustee under Section
8.06 hereof.

     (b) If 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 actions or proceedings at law or in
equity for the collection of the sums so due and unpaid, and may enforce any
such judgment or final decree against the Company or any other obligor on the
Securities and collect in the manner provided by law out of the property of the
Company or any other obligor on such series of Securities wherever situated, the
moneys adjudged or decreed to be payable.

     (c) If there shall be pending proceedings for the bankruptcy or for the
reorganization of the Company or any other obligor on the Securities under the
United States Bankruptcy Code or any other applicable law, or in case a receiver
or trustee shall have been appointed for the property of the Company or such
other obligor, or in the case of any similar judicial proceedings relative to
the Company or other obligor upon the Securities, or to the creditors or
property of the Company or such other obligor, the Trustee, irrespective of
whether the principal of the Securities shall then be due and payable as therein
expressed or by declaration or otherwise and irrespective of whether the Trustee
shall have made any demand pursuant to this Section 7.02, shall be entitled and
empowered, by intervention in such proceedings or otherwise, to file and prove a
claim or claims for the whole amount of principal and any premium and interest
owing and unpaid in respect of the Securities, and, in case of any judicial
proceedings, to file such proofs of claim and other papers or documents as may
be necessary or advisable in order to have the claims of the Trustee (including
any amounts due to the Trustee under Section 8.06 hereof) and of the Holders of
Securities allowed in such judicial proceedings relative to the Company or any
other obligor on the Securities, its or their creditors, or its or their
property, and to collect and receive any moneys or other property payable or
deliverable on any such claims, and to distribute the same after the deduction
of its charges and expenses.

     (d) All claims and rights of action under this Indenture, or under any of
the Securities, may be enforced by the Trustee without the possession of any of
the Securities, or the production thereof in 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 be for the ratable benefit of the Holders of the
Securities in respect of which such action was taken.

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

     SECTION 7.03. APPLICATION OF MONEYS COLLECTED BY TRUSTEE. Any moneys
collected by the Trustee with respect to any of the Securities pursuant to this
Article shall be

                                       27
<Page>

applied in the order following, at the date or dates fixed by the Trustee for
the distribution of such moneys, upon presentation of the several Securities,
and stamping thereon the payment, if only partially paid, and upon surrender
thereof if fully paid.

     FIRST:    To the payment of all amounts due to the Trustee pursuant to
Section 8.06 hereof;

     SECOND:   If the principal of the outstanding Securities in respect of
which such moneys have been collected shall not have become due and be unpaid,
to the payment of interest on the Securities, in the order of the maturity of
the installments of such interest, with interest (to the extent allowed by law
and to the extent that such interest has been collected by the Trustee) upon the
overdue installments of interest at the rate borne by the Securities, such
payments to be made ratably to the persons entitled thereto, and then to the
payment to the Holders entitled thereto of the unpaid principal of and
applicable premium on any of the Securities which shall have become due (other
than Securities previously called for redemption for the payment of which moneys
are held pursuant to the provisions of this Indenture), whether at stated
maturity or by redemption, in the order of their due dates, beginning with the
earliest due date, and if the amount available is not sufficient to pay in full
all Securities due on any particular date, then to the payment thereof ratably,
according to the amounts of principal and applicable premium due on that date,
to the Holders entitled thereto, without any discrimination or privilege;

     THIRD:    If the principal of the outstanding Securities in respect of
which such moneys have been collected shall have become due, by declaration or
otherwise, to the payment of the whole amount then owing and unpaid upon the
Securities for principal and any premium and interest thereon, with interest on
the overdue principal and any premium and (to the extent allowed by law and to
the extent that such interest has been collected by the Trustee) upon overdue
installments of interest at the rate borne by the Securities; and in case such
moneys shall be insufficient to pay in full the whole amount so due and unpaid
upon the Securities, then to the payment of such principal and any premium and
interest without preference or priority of principal and any premium over
interest, or of interest over principal and any premium or of any installment of
interest over any other installment of interest, or of any Security over any
other Security, ratably to the aggregate of such principal and any premium and
accrued and unpaid interest; and

     FOURTH:   to the payment of the remainder, if any, to the Company or its
successors or assigns, or to whomsoever may lawfully be entitled to the same, or
as a court of competent jurisdiction may determine.

     SECTION 7.04. PROCEEDINGS BY SECURITY HOLDERS.

     (a) No Holder of any Security shall have any right by virtue of or by
availing of any provision of this Indenture to institute any suit, action or
proceeding in equity or at law upon or under or with respect to this Indenture
or for the appointment of a receiver or trustee, or for any other remedy
hereunder, unless such Holder previously shall have given to the Trustee written
notice of an Event of Default with respect to such Security and of the
continuance thereof, as hereinabove provided, and unless also Security holders
of a majority in aggregate principal amount of the Securities then outstanding
affected by such Event of Default shall have made

                                       28
<Page>

written request upon the Trustee to institute such action, suit or proceeding in
its own name as Trustee hereunder and shall have offered to the Trustee such
reasonable indemnity as it may require against the costs, expenses and
liabilities to be incurred therein or thereby, and the Trustee for 60 days after
its receipt of such notice, request and offer of indemnity, shall have neglected
or refused to institute any such action, suit or proceeding.

     (b) Notwithstanding any other provision in this Indenture, however, the
rights of any Holder of any Security to receive payment of the principal of and
any premium and interest on such Security, on or after the respective due dates
expressed in such Security or on the applicable redemption date, or to institute
suit for the enforcement of any such payment on or after such respective dates
shall not be impaired or affected without the consent of such Holder.

     SECTION 7.05. PROCEEDINGS BY TRUSTEE. 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 by suit in equity or by action at law or by proceeding in
bankruptcy or otherwise, whether for the specific enforcement of any covenant or
agreement contained in this Indenture or in aid of the exercise of any power
granted to it under this Indenture, or to enforce any other legal or equitable
right vested in the Trustee by this Indenture or by law.

     SECTION 7.06. REMEDIES CUMULATIVE AND CONTINUING. All powers and remedies
given by this Article Seven to the Trustee or to the Security holders shall, to
the extent permitted by law, be deemed cumulative and not exclusive of any
powers and remedies hereof or of any other powers and remedies available to the
Trustee or the Holders of the Securities, by judicial proceedings or otherwise,
to enforce the performance or observance of the covenants and agreements
contained in this Indenture, and no delay or omission of the Trustee or of any
Holder of any of the Securities in exercising any right or power accruing upon
any 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 Section 7.04 hereof, every power and
remedy given by this Article Seven or by law to the Trustee or to the Security
holders may be exercised from time to time, and as often as shall be deemed
expedient, by the Trustee or by the Security holders.

     SECTION 7.07. DIRECTION OF PROCEEDINGS AND WAIVER OF DEFAULTS BY MAJORITY
OF SECURITY HOLDERS. The Holders of a majority in aggregate principal amount of
the Securities at the time outstanding 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; provided,
that (subject to Section 8.01 hereof) the Trustee shall have the right to
decline to follow any such direction if the Trustee being advised by counsel
determines that the action or proceeding so directed may not lawfully be taken
or if the Trustee in good faith by its board of directors or trustees, executive
committee, or a trust committee of directors or trustees or responsible officers
shall determine that the action or proceeding so directed would involve the
Trustee in personal liability or would be unduly prejudicial to the rights of
Security holders not joining in such directions. The Holders of a majority in
aggregate principal amount of the Securities at the time outstanding may on
behalf of all of the Holders of the Securities waive any past default or Event
of Default hereunder and its consequences except

                                       29
<Page>

a default in the payment of principal of or any premium or interest on the
Securities. Upon any such waiver the Company, the Trustee and the Holders of the
Securities shall be restored to their former positions and rights hereunder,
respectively, but no such waiver shall extend to any subsequent or other default
or Event of Default or impair any right consequent thereon. Whenever any default
or Event of Default hereunder shall have been waived as permitted by this
Section 7.07, said default or Event of Default shall for all purposes of the
Securities and this Indenture be deemed to have been cured and to be not
continuing.

     SECTION 7.08. NOTICE OF DEFAULT. The Trustee shall, within 90 days after
the occurrence of a default, give to all Holders of the Securities, in the
manner provided in section 14.10, notice of such default, unless such default
shall have been cured before the giving of such notice; the term "default" for
the purpose of this Section 7.08 being hereby defined to be any event which is
or after notice or lapse of time or both would become an Event of Default;
provided that, except in the case of default in the payment of the principal of
or any premium or interest on any of the Securities, or in the payment of any
sinking or purchase fund installments, the Trustee shall be protected in
withholding such notice if and so long as its board of directors or trustees,
executive committee, or a trust committee of directors or trustees or
responsible officers in good faith determines that the withholding of such
notice is in the interests of the Holders of the Securities. The Trustee shall
not be charged with knowledge of any Event of Default unless a responsible
officer of the Trustee assigned to the corporate trustee department of the
Trustee shall have actual knowledge of such Event of Default.

     SECTION 7.09. UNDERTAKING TO PAY COSTS. All parties to this Indenture
agree, and each Holder of any Security by acceptance thereof shall be deemed to
have agreed, that any court may in its discretion require, in any suit for the
enforcement of any right or remedy under this Indenture or in any suit against
the Trustee for any action taken or omitted by it as Trustee, the filing by any
party litigant in such suit of an undertaking to pay the costs of such suit, and
that such court may in its discretion assess reasonable costs, including
reasonable attorneys' fees, against any party litigant in such suit, having due
regard to the merits and good faith of the claims or defenses made by such party
litigant; but this Section 7.09 shall not apply to any suit instituted by the
Trustee, or to any suit instituted by any Security holder, or group of Security
holders, holding in the aggregate more than 10% in principal amount of the
Securities outstanding, or to any suit instituted by any Security holder for the
enforcement of the payment of the principal of or any premium or interest on any
Security on or after the due date expressed in such Security or the applicable
redemption date.

                                 ARTICLE EIGHT.

                             CONCERNING THE TRUSTEE

     SECTION 8.01. DUTIES AND RESPONSIBILITIES OF TRUSTEE.

     (a) The Trustee, prior to the occurrence of an Event of Default and after
the curing of all Events of Default which may have occurred, undertakes to
perform such duties and only such duties as are specifically set forth in this
Indenture. If an Event of Default has occurred (which has not been cured or
waived), the Trustee shall exercise such of the rights and powers vested in

                                       30
<Page>

it by this Indenture, and use the same degree of care and skill in their
exercise, as a prudent man would exercise or use under the circumstances in the
conduct of his own affairs.

     (b) No provisions 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 any Event of Default and after the
     curing or waiving of all Events of Default which may have occurred

               (A) the duties and obligations of the Trustee shall be determined
          solely by the express provisions of this Indenture, and the Trustee
          shall not be liable except for the performance of such duties and
          obligations as are specifically set forth in this Indenture, and no
          implied covenants or obligations shall be read into this Indenture
          against the Trustee; and

               (B) in the absence of bad faith on the part of the Trustee, the
          Trustee may 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 officers of the Trustee, unless it
     shall be proved that the Trustee was negligent in ascertaining the
     pertinent facts; and

          (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 Section 7.07
     hereof 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.

     SECTION 8.02. RELIANCE ON DOCUMENTS, OPINIONS, ETC. Except as otherwise
provided in Section 8.01 hereof:

     (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, note or other paper or document
believed by it to be genuine and to have been signed or presented by the proper
party or parties;

     (b) any request, direction, order or demand of the Company mentioned herein
shall be sufficiently evidenced by an Officers' Certificate (unless other
evidence in respect thereof is herein specifically prescribed); and any Board
Resolution may be evidenced to the Trustee by a copy thereof certified by the
Secretary or an Assistant Secretary of the Company;

                                       31
<Page>

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

     (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 Security holders, pursuant to this Indenture, unless such Security
holders shall have offered to the Trustee reasonable security or indemnity
against the costs, expenses and liabilities which may be incurred by such
exercise;

     (e) the Trustee shall not be liable for any action taken, suffered or
omitted 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) prior to the occurrence of an Event of Default hereunder and after the
curing or waiving of all Events of Default, 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, note or other paper or document, unless requested in writing to
do so by the Holders of at least a majority in principal amount of the then
outstanding Securities; provided 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 this
Indenture, the Trustee may require reasonable indemnity against such expense or
liability as a condition to so proceeding;

     (g) no provision of this Indenture shall require the Trustee to extend or
risk its own funds or otherwise incur any financial liability in the performance
of any of its duties hereunder, or in the exercise of any of its rights or
powers, if it shall have reasonable grounds for believing that repayment of such
funds or adequate indemnity against such risk or liability is not reasonably
assured to it; and

     (h) the Trustee may execute any of the trusts or powers hereunder or
perform any duties hereunder either directly or through agents or attorneys;
provided that the Trustee shall not be liable for the conduct or acts of any
such agent or attorney that shall have been appointed in accordance herewith
with due care.

     SECTION 8.03. NO RESPONSIBILITY FOR RECITALS, ETC. The recitals contained
herein and in the Securities (except in the certificate of authentication) shall
be taken as the statements of the Company, and the Trustee assumes no
responsibility for the correctness of the same. The Trustee makes no
representations as to the validity or sufficiency of this Indenture or of the
Securities. The Trustee shall not be accountable for the use or application by
the Company of any Securities or the proceeds of any Securities authenticated
and delivered by the Trustee in conformity with this Indenture. The Trustee
shall not be responsible for recording or filing this Indenture, any
supplemental indenture, or any financing or continuation statement in any public
office at any time or times.

     SECTION 8.04. TRUSTEE, AUTHENTICATING AGENT, PAYING AGENT OR REGISTRAR MAY
OWN SECURITIES. The Trustee and any Authenticating Agent or paying agent in its

                                       32
<Page>

individual or other capacity, may become the owner or pledgee of Securities with
the same rights it would have if it were not Trustee, Authenticating Agent or
paying agent.

     SECTION 8.05. MONEYS TO BE HELD IN TRUST. Subject to Section 4.04 hereof,
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 may allow and credit to the Company interest on any money received
hereunder at such rate, if any, as may be agreed upon by the Company and the
Trustee from time to time as may be permitted by law.

     SECTION 8.06. COMPENSATION AND EXPENSES OF TRUSTEE. The Company covenants
and agrees to pay to the Trustee from time to time, and the Trustee shall be
entitled to, reasonable compensation (which shall not be limited by any law in
regard to the compensation of a trustee of an express trust), and the Company
shall pay or reimburse the Trustee upon its request for all reasonable expenses,
disbursements and advances incurred or made by the Trustee in accordance with
this Indenture (including the reasonable compensation and the reasonable
expenses and disbursements of its counsel and agents, including any
Authenticating Agents, 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 for, and to hold
it harmless against, any loss, liability or expense incurred without negligence
or bad faith on the part of the Trustee and arising out of or in connection with
the acceptance or administration of this trust, including the costs and expenses
of defending itself against any claim or liability. The obligations of the
Company under this Section 8.06 to compensate 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 Securities upon all property and funds held or
collected by the Trustee as such, except funds held in trust for the benefit of
the Holders of any particular Securities.

     SECTION 8.07. OFFICERS' CERTIFICATE AS EVIDENCE. Whenever in the
administration of this Indenture, the Trustee shall deem it necessary or
desirable that a matter be proved or established prior to the taking, suffering
or omitting of any action hereunder, such matter (unless other evidence in
respect thereof is herein specifically prescribed) may, in the absence of
negligence or bad faith on the part of the Trustee, be deemed to be conclusively
proved and established by an Officers' Certificate delivered to the Trustee, and
such Officers' Certificate, in the absence of negligence or bad faith on the
part of the Trustee, shall be full warranty to the Trustee for any action taken,
suffered or omitted by it under this Indenture in reliance thereon.

     SECTION 8.08. CONFLICTING INTEREST OF TRUSTEE. The Trustee shall be subject
to and shall comply with the provisions of Section 310 of the TIA. Nothing in
this Indenture shall be deemed to prohibit the Trustee or the Company from
making any application permitted pursuant to such section.

     SECTION 8.09. EXISTENCE AND ELIGIBILITY OF TRUSTEE. There shall at all
times be a Trustee hereunder which Trustee shall at all times be a corporation
organized and doing business under the laws of the United States or any State
thereof or of the District of Columbia

                                       33
<Page>

(or a corporation or other Person permitted to act as trustee by the
Commission), subject to supervision or examination by such bodies and authorized
under such laws to exercise corporate trust powers and having a combined capital
and surplus of at least $_________. If such corporation publishes reports of
condition at least annually, pursuant to law or to the requirements of the
aforesaid authority, then for the purposes of this Section 8.09, the combined
capital and surplus shall be deemed to be as set forth in its most recent report
of condition so published. No obligor upon the Securities or Person directly or
indirectly controlling, controlled by, or under common control with such obligor
shall serve as Trustee. If at any time the Trustee shall cease to be eligible in
accordance with this Section 8.09, the Trustee shall resign immediately in the
manner and with the effect specified in Section 8.10 hereof.

     SECTION 8.10. RESIGNATION OR REMOVAL OF TRUSTEE.

     (a) Pursuant to the provisions of this Article, the Trustee may at any time
resign and be discharged of the trusts created by this Indenture by giving
written notice to the Company specifying the day upon which such resignation
shall take effect, and such resignation shall take effect immediately upon the
later of the appointment of a successor trustee and such day.

     (b) Any Trustee may be removed at any time by an instrument or concurrent
instruments in writing filed with such Trustee and signed and acknowledged by
the Holders of a majority in principal amount of the then outstanding Securities
or by their attorneys in fact duly authorized.

     (c) So long as no Event of Default has occurred and is continuing, and no
event has occurred and is continuing that, with the giving of notice or the
lapse of time or both, would become an Event of Default, the Company may remove
any Trustee upon written notice to the Holder of each Security outstanding and
the Trustee.

     (d) If at any time (1) the Trustee shall cease to be eligible in accordance
with Section 8.09 hereof and shall fail to resign after written request therefor
by the Company or by any Holder who has been a bona fide Holder for at least six
months, (2) the Trustee shall fail to comply with Section 8.08 hereof after
written request therefor by the Company or any such Holder, or (3) the Trustee
shall become incapable of acting or shall be adjudged a bankrupt or insolvent or
a receiver of the Trustee or 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 the
Trustee may be removed forthwith by an instrument or concurrent instruments in
writing filed with the Trustee and either:

          (1) signed by the President or any Vice President of the Company and
     attested by the Secretary or an Assistant Secretary of the Company; or

          (2) signed and acknowledged by the Holders of a majority in principal
     amount of outstanding Securities or by their attorneys in fact duly
     authorized.

     (e) Any resignation or removal of the Trustee shall not become effective
until acceptance of appointment by the successor Trustee as provided in Section
8.11 hereof.

     SECTION 8.11. APPOINTMENT OF SUCCESSOR TRUSTEE.

                                       34
<Page>

     (a) If at any time the Trustee shall resign or be removed, the Company, by
a Board Resolution, shall promptly appoint a successor Trustee.

     (b) The Company shall provide written notice of its appointment of a
Successor Trustee to the Holder of each Security outstanding following any such
appointment.

     (c) If no appointment of a successor Trustee shall be made pursuant to
Section 8.11(a) hereof within 60 days after appointment shall be required, any
Security holder or the resigning Trustee may apply to any court of competent
jurisdiction to appoint a successor Trustee. Said court may thereupon after such
notice, if any, as such court may deem proper and prescribe, appoint a successor
Trustee.

     (d) Any Trustee appointed under this Section 8.11 as a successor Trustee
shall be a bank or trust company eligible under Section 8.09 hereof and
qualified under Section 8.08 hereof.

     SECTION 8.12. ACCEPTANCE BY SUCCESSOR TRUSTEE.

     (a) Any successor Trustee appointed as provided in Section 8.11 hereof
shall execute, acknowledge and deliver to the Company and to its predecessor
Trustee an instrument accepting such appointment hereunder, and thereupon the
resignation or removal of the predecessor Trustee shall become effective and
such successor Trustee, without any further act, deed or conveyance, shall
become vested with all the rights, powers, duties and obligations of its
predecessor hereunder, with like effect as if originally named as Trustee
herein; but nevertheless, on the written request of the Company or of the
successor Trustee, the Trustee ceasing to act shall, upon payment of any amounts
then due it pursuant to Section 8.06 hereof, execute and deliver an instrument
transferring to such successor Trustee all the rights and powers of the Trustee
so ceasing to act. Upon request of any such successor Trustee, the Company shall
execute any and all instruments in writing in order more fully and certainly to
vest in and confirm to such successor Trustee all such rights and powers. Any
Trustee ceasing to act shall, nevertheless, retain a lien upon all property or
funds held or collected by such Trustee to secure any amounts then due it
pursuant to Section 8.06 hereof.

     (b) No successor Trustee shall accept appointment as provided in this
Section 8.12 unless at the time of such acceptance such successor Trustee shall
be qualified under Section 8.08 hereof and eligible under Section 8.09 hereof.

     (c) Upon acceptance of appointment by a successor Trustee as provided in
this Section 8.12, the successor Trustee shall mail notice of its succession
hereunder to all Holders of Securities as the names and addresses of such
Holders appear on the registry books.

     SECTION 8.13. SUCCESSION BY MERGER, ETC.

     (a) Any corporation into which the Trustee may be merged or converted or
with which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any
corporation succeeding to all or substantially all of the corporate trust
business of the Trustee, shall be the successor of the Trustee hereunder without
the execution or filing of any paper or any further act on the part of any of
the parties hereto, provided such corporation shall be otherwise qualified and
eligible under this Article.

                                       35
<Page>

     (b) If at the time such successor to the Trustee shall succeed to the
trusts created by this Indenture any of the Securities shall have been
authenticated but not delivered, any such successor to the Trustee may adopt the
certificate of authentication of any predecessor Trustee, and deliver such
Securities so authenticated; and in case at that time any of the Securities
shall not have been authenticated, any successor to the Trustee may authenticate
such Securities either in the name of any predecessor hereunder or in the name
of the successor Trustee; and in all such cases such certificates shall have the
full force which it is anywhere in the Securities or in this Indenture provided
that the certificates of the Trustee shall have; provided that the right to
adopt the certificate of authentication of any predecessor Trustee or
authenticate Securities in the name of any predecessor Trustee shall apply only
to its successor or successors by merger, conversion or consolidation.

     SECTION 8.14. LIMITATIONS ON RIGHTS OF TRUSTEE AS A CREDITOR.

     The Trustee shall be subject to, and shall comply with, the provisions of
Section 311 of the TIA.

     SECTION 8.15. AUTHENTICATING AGENT.

     (a) There may be one or more Authenticating Agents appointed by the Trustee
with the written consent of the Company, with power to act on its behalf and
subject to the direction of the Trustee in the authentication and delivery of
Securities in connection with transfers and exchanges under Sections 2.06, 2.07,
2.08, 2.13, 3.03, and 12.04 hereof, as fully to all intents and purposes as
though such Authenticating Agents had been expressly authorized by those
Sections to authenticate and deliver Securities. For all purposes of this
Indenture, the authentication and delivery of Securities by any Authenticating
Agent pursuant to this Section 8.15 shall be deemed to be the authentication and
delivery of such Securities "by the Trustee." Any such Authenticating Agent
shall be a bank or trust company or other Person of the character and
qualifications set forth in Section 8.09 hereof.

     (b) Any corporation into which any Authenticating Agent may be merged or
converted or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which any Authenticating Agent
shall be a party, or any corporation succeeding to the corporate trust business
of any Authenticating Agent, shall be the successor of such Authenticating Agent
hereunder, if such successor corporation is otherwise eligible under this
Section 8.15, without the execution or filing of any paper or any further act on
the part of the parties hereto or such Authenticating Agent or such successor
corporation.

     (c) 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 terminate the agency of any Authenticating Agent by giving written notice
of termination to such Authenticating Agent and to the Company. Upon receiving
such a notice of resignation or upon such a termination, or in case at any time
any Authenticating Agent shall cease to be eligible under this Section 8.15, the
Trustee may, with the written consent of the Company, appoint a successor
Authenticating Agent, and upon so doing shall give written notice of such
appointment to the Company and shall mail, in the manner provided in Section
14.10, notice of such appointment to the Holders of Securities.

                                       36
<Page>

     (d) The Trustee agrees to pay to each Authenticating Agent from time to
time reasonable compensation for its services, and the Trustee shall be entitled
to be reimbursed for such payments, in accordance with Section 8.06 hereof.

     (e) Sections 8.02, 8.03, 8.06, 8.07 and 8.09 hereof shall be applicable to
any Authenticating Agent.

                                  ARTICLE NINE.

                         CONCERNING THE SECURITY HOLDERS

     SECTION 9.01. ACTION BY SECURITY HOLDERS. Whenever in this Indenture it is
provided that the Holders of a specified percentage in aggregate principal
amount of the Securities may take any action, the fact that at the time of
taking any such action the Holders of such specified percentage have joined
therein may be evidenced (a) by any instrument or any number of instruments of
similar tenor executed by such Security holders in person or by agent or proxy
appointed in writing, (b) by the record of such Security holders voting in favor
thereof at any meeting of Security holders duly called and held in accordance
with Article Ten hereof, or (c) by a combination of such instrument or
instruments and any such record of such a meeting of Security holders.

     SECTION 9.02. PROOF OF EXECUTION BY SECURITY HOLDERS.

     (a) Subject to Sections 8.01, 8.02 and 10.05 hereof, proof of the execution
of any instruments by a Security holder or the agent or proxy for such Security
holder shall be sufficient if made in accordance with such reasonable rules and
regulations as may be prescribed by the Trustee or in such manner as shall be
satisfactory to the Trustee. The ownership of Securities shall be proved by the
register for the Securities maintained by the Trustee.

     (b) The record of any Security holders' meeting shall be proven in the
manner provided in Section 10.06 hereof.

     SECTION 9.03. WHO DEEMED ABSOLUTE OWNERS. Subject to Sections 2.04(f) and
9.01 hereof, the Company, the Trustee, any paying agent and any Authenticating
Agent shall deem the person in whose name any Security shall be registered upon
the register for the Securities to be, and shall treat such person as, the
absolute owner of such Security (whether or not such Security shall be overdue)
for the purpose of receiving payment of or on account of the principal and
premium, if any, and interest on such Security, and for all other purposes; and
neither the Company nor the Trustee nor any paying agent nor any Authenticating
Agent shall be affected by any notice to the contrary. All such payments shall
be valid and effectual to satisfy and discharge the liability upon any such
Security to the extent of the sum or sums so paid.

     SECTION 9.04. COMPANY-OWNED SECURITIES DISREGARDED. In determining whether
the Holders of the requisite aggregate principal amount of outstanding
Securities have concurred in any direction, consent or waiver under this
Indenture, Securities which are owned by the Company or any other obligor on the
Securities or by any person directly or indirectly controlling or controlled by
or under direct or indirect common control with the Company or any other obligor
on the Securities shall be disregarded and deemed not to be outstanding for the

                                       37
<Page>

purpose of any such determination; provided that, for the purposes of
determining whether the Trustee shall be protected in relying on any such
direction, consent or waiver, only Securities which the Trustee knows are so
owned shall be so disregarded. Securities so owned which have been pledged in
good faith to third parties may be regarded as outstanding for the purposes of
this Section 9.04 if the pledgee shall establish to the satisfaction of the
Trustee the pledgee's right to take action with respect to such Securities and
that the pledgee is not a person directly or indirectly controlling or
controlled by or under direct or indirect common control with the Company or any
such other obligor. In the case of a dispute as to such right, any decision by
the Trustee taken upon the advice of counsel shall be full protection to the
Trustee.

     SECTION 9.05. REVOCATION OF CONSENTS; FUTURE HOLDERS BOUND. Except as may
be otherwise required in the case of a Global Security by the applicable rules
and regulations of the Depositary, at any time prior to the taking of any action
by the Holders of the percentage in aggregate principal amount of the Securities
specified in this Indenture in connection with such action, any Holder of a
Security, which has been included in the Securities the Holders of which have
consented to such action may, by filing written notice with the Trustee at the
corporate trust office of the Trustee and upon proof of ownership as provided in
Section 9.02(a) hereof, revoke such action so far as it concerns such Security.
Except as aforesaid, any such action taken by the Holder of any Security shall
be conclusive and binding upon such Holder and upon all future Holders and
owners of such Security and of any Securities issued in exchange, substitution
or upon registration of transfer therefor, irrespective of whether or not any
notation thereof is made upon such Security or such other Securities.

     SECTION 9.06. RECORD DATE FOR SECURITY HOLDER ACTS. If the Company shall
solicit from the Security holders any request, demand, authorization, direction,
notice, consent, waiver or other act, the Company may, at its option, by Board
Resolution, fix in advance a record date for the determination of Security
holders entitled to give such request, demand, authorization, direction, notice,
consent, waiver or other act, 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 act may be given before or after the record
date, but only the Security holders of record at the close of business on the
record date shall be deemed to be Security holders for the purpose of
determining whether Holders of the requisite aggregate principal amount of
outstanding Securities have authorized or agreed or consented to such request,
demand, authorization, direction, notice, consent, waiver or other act, and for
that purpose the outstanding Securities shall be computed as of the record date;
provided that no such request, demand, authorization, direction, notice,
consent, waiver or other act by the Security holders on the record date shall be
deemed effective unless it shall become effective pursuant to this Indenture not
later than six months after the record date. Any such record date shall be at
least 30 days prior to the date of the solicitation to the Security holders by
the Company.

INTEREST RATE:                           MATURITY DATE:

     OGE ENERGY CORP., a corporation of the State of Oklahoma (the "COMPANY")
for value received hereby promises to pay to Cede & Co. or registered assigns,
the principal sum of

                                                                         DOLLARS

on the Maturity Date set forth above, and to pay interest thereon from the
Original Issue Date (or if this Global Security has two or more Original Issue
Dates, interest shall, beginning on each such Original Issue Date, begin to
accrue for that part of the principal amount to which that Original Issue Date
is applicable) set forth above or from the most recent Interest Payment Date to
which interest has been paid or duly provided for, semiannually in arrears on
the ________ and ___________ in each year, commencing on the first such Interest

the applicable Original Issue Date set forth above, at the per annum Interest
Rate set forth above, until the principal hereof is paid or made available for
payment. No interest shall accrue on the Maturity Date, so long as the principal
amount of this Global Security is paid on the Maturity Date. The interest so
payable and punctually paid or duly provided for on any such Interest Payment
Date will, as provided in the Indenture, be paid to the Person in whose name
this Security is registered at the close of business on the Regular Record Date
for such interest, which shall be the ______________ or _______________, as the
case may be, next preceding such Interest Payment Date; provided, that the first
Interest Payment Date for any part of this Security, the Original Issue Date of
which is after a Regular Record Date but prior to the applicable Interest
Payment Date, shall be the Interest Payment Date following the next succeeding
Regular Record Date; and provided, that interest payable on the Maturity Date
set forth above or, if applicable, upon redemption or acceleration, shall be
payable to the Person to whom principal shall be payable. Except as otherwise
provided in the Indenture (as defined below), any such interest not so
punctually paid or duly provided for will forthwith cease to be payable to the
Holder on such Regular Record Date and shall be paid to the Person in whose name
this Security is registered at the close of business on a Special Record Date
for the payment of such defaulted interest to be fixed by the Trustee, notice
whereof shall be given to Security holders not more than fifteen days or fewer
than ten days prior to such Special Record Date. On or before 10:00 a.m., New
York City time, or such other time as shall be agreed upon between the Trustee
and the Depositary, of the day on which such payment of interest is due on this
Global Security (other than maturity), the Trustee shall pay to the Depositary
such interest in same day funds. On or before 10:00 a.m., New York City time, or
such other time as shall be agreed upon between the Trustee and the Depositary,
of the day on which principal, interest payable at maturity and premium, if any,
is due on this Global Security, the Trustee shall deposit with the Depositary
the amount equal to the principal, interest payable at maturity and premium, if
any, by wire transfer into the account specified by the Depositary. As a
condition to the payment, on the Maturity Date or upon redemption or
acceleration, of any part of the principal and applicable premium of this Global
Security, the Depositary shall surrender, or cause to be surrendered, this
Global Security to the Trustee, whereupon a new Global Security shall be issued
to the Depositary.

     This Global Security is a global security in respect of a duly authorized
issue of Debt Securities (the "SECURITIES OF THIS SERIES", which term includes
any Global Securities representing such Securities) of the Company issued and to
be issued under an Indenture dated as of __________ between the Company and UMB
Bank, N.A., as trustee (herein called the "TRUSTEE", which term includes any
successor Trustee under the Indenture) and indentures supplemental thereto
(collectively, the "INDENTURE"). Under the Indenture, one or more series of debt
securities may be issued and, as used herein, the term "Securities" refers to
the Securities of this Series and any other outstanding series of Securities.
Reference is hereby made for a more complete statement of the respective rights,
limitations of rights, duties and immunities under the Indenture of the Company,
the Trustee and the Security holders and of the terms upon which the Securities
are and are to be authenticated and delivered. This Global Security has been
issued in respect of the series designated on the first page hereof, limited in
aggregate principal amount to $____________.

     Each Security of this Series shall be dated and issued as of the date of
its authentication by the Trustee and shall bear an Original Issue Date or
Dates. Each Security or Global Security issued upon transfer, exchange or
substitution of such Security or Global Security shall bear the

                                       A-2
<Page>

Original Issue Date or Dates of such transferred, exchanged or substituted
Security or Global Security, as the case may be.

     [As applicable, one of the following two sentences: This Global Security
may not be redeemed prior to ____________, __________. This Global Security is
not redeemable prior to the Maturity Date set forth on the first page hereof.)
[If applicable: On or after _________, 20__, this Global Security is redeemable
in whole or in part in increments of $1,000 (provided that any remaining
principal amount of this Global Security shall be at least $_________) at the
option of the Company at the following redemption prices (expressed as a
percentage of the principal amount to be redeemed) plus accrued interest to the
redemption date:

          REDEMPTION PERIODS                     REDEMPTION PRICES

Notice of redemption will be given by mail to Holders of Securities of this
Series not less than 30 or more than 60 days prior to the date fixed for
redemption, all as provided in the Indenture. In the event of redemption of this
Global Security in part only, a new Global Security or Securities of like tenor
and series for the unredeemed portion hereof will be issued in the name of the
Security holder hereof upon the surrender hereof.]

     Interest payments for this Global Security shall be computed and paid on
the basis of a 360-day year of twelve 30-day months. In any case where any
Interest Payment Date or date on which the principal of this Global Security is
required to be paid is not a Business Day, then payment of principal, premium or
interest need not be made on such date but may be made on the next succeeding
Business Day with the same force and effect as if made on such Interest Payment
Date or date on which the principal of this Global Security is required to be
paid and, in the case of timely payment thereof, no interest shall accrue for
the period from and after such Interest Payment Date or the date on which the
principal of this Global Security is required to be paid.

     The Company, at its option, and subject to the terms and conditions
provided in the Indenture, will be discharged from any and all obligations in
respect of the Securities (except for certain obligations including obligations
to register the transfer or exchange of Securities, replace stolen, lost or
mutilated Securities, maintain paying agencies and hold monies for payment in
trust, all as set forth in the Indenture) if the Company deposits with the
Trustee money, U.S. Government Obligations which through the payment of interest
thereon and principal thereof in accordance with their terms will provide money,
or a combination of money and U.S. Government Obligations, in any event in an
amount sufficient, without reinvestment, to pay all the principal of and any
premium and interest on the Securities on the dates such payments are due in
accordance with the terms of the Securities.

     If an Event of Default shall occur and be continuing, the principal of the
Securities may be declared due and payable in the manner and with the effect
provided in the Indenture.

     The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modifications of the rights and obligations of the
Company and the rights of the Security holders under the Indenture at any time
by the Company and the Trustee with the

                                       A-3
<Page>

consent of the Holders of not less than a majority in principal amount of the
outstanding Securities. Any such consent or waiver by the Holder of this Global
Security shall be conclusive and binding upon such Holder and upon all future
Holders of this Global Security and of any Security issued upon the registration
of transfer hereof or in exchange therefor or in lieu thereof whether or not
notation of such consent or waiver is made upon the Security.

     As set forth in and subject to the provisions of the Indenture, no Holder
of any Securities will have any right to institute any proceeding with respect
to the Indenture or for any remedy thereunder unless such Holder shall have
previously given to the Trustee written notice of a continuing Event of Default
with respect to such Securities, the Holders of not less than a majority in
principal amount of the outstanding Securities affected by such Event of Default
shall have made written request and offered reasonable indemnity to the Trustee
to institute such proceeding as Trustee and the Trustee shall have failed to
institute such proceeding within 60 days; provided, however, that such
limitations do not apply to a suit instituted by the Holder hereof for the
enforcement of payment of the principal of and any premium or interest on this
Security on or after the respective due dates expressed here.

     No reference herein to the Indenture and to provisions of this Global
Security or of the Indenture shall alter or impair the obligation of the
Company, which is absolute and unconditional, to pay the principal of and any
premium and interest on this Global Security at the times, places and rates and
the coin or currency prescribed in the Indenture.

     As provided in the Indenture and subject to certain limitations therein set
forth, this Global Security may be transferred only as permitted by the legend
hereto.

     If at any time the Depositary for this Global Security notifies the Company
that it is unwilling or unable to continue as Depositary for this Global
Security or if at any time the Depositary for this Global Security shall no
longer be eligible or in good standing under the Securities Exchange Act of
1934, as amended, or other applicable statute or regulation, the Company shall
appoint a successor Depositary with respect to this Global Security. If a
successor Depositary for this Global Security is not appointed by the Company
within 90 days after the Company receives such notice or becomes aware of such
ineligibility, the Company's election to issue this Security in global form
shall no longer be effective with respect to this Global Security and the
Company will execute, and the Trustee, upon receipt of a Company Order for the
authentication and delivery of individual Securities of this Series in exchange
for this Global Security, will authenticate and deliver individual Securities of
this Series of like tenor and terms in definitive form in an aggregate principal
amount equal to the principal amount of this Global Security.

     The Company may at any time and in its sole discretion determine that all
Securities of this Series (but not less than all) issued or issuable in the form
of one or more Global Securities shall no longer be represented by such Global
Security or Securities. In such event, the Company shall execute, and the
Trustee, upon receipt of a Company Order for the authentication and delivery of
individual Securities of this Series in exchange for such Global Security, shall
authenticate and deliver, individual Securities of this Series of like tenor and
terms in definitive form in an aggregate principal amount equal to the principal
amount of such Global Security or Securities in exchange for such Global
Security or Securities.

                                       A-4

     Under certain circumstances specified in the Indenture, the Depositary may
be required to surrender any two or more Global Securities which have identical
terms (but which may have differing Original Issue Dates) to the Trustee, and
the Company shall execute and the Trustee shall authenticate and deliver to, or
at the direction of, the Depositary a Global Security in principal or amount
equal to the aggregate principal amount of and with all terms identical to, the
Global Securities surrendered thereto and that shall indicate all Original Issue
Dates and the principal amount applicable to each such Original Issue Date.

     The Indenture and the Securities shall be governed by, and construed in
accordance with, the laws of the State of Oklahoma.

     Unless the certificate of authentication hereon has been executed by the
Trustee, directly or through an Authenticating Agent by manual signature of an
authorized officer, this Global Security shall not be entitled to any benefit
under the Indenture or be valid or obligatory for any purpose.

     All terms used in this Global Security which are defined in the Indenture
shall have the meanings assigned to them in the Indenture unless otherwise
indicated herein.

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

on the Security shall be paid by wire transfer of immediately available funds to
a bank within the continental United States (designated by such Holder in its
request) or by direct deposit into the account of such Holder designated by such

                          [FORM OF REVERSE OF SECURITY]
                                OGE ENERGY CORP.
                                    SECURITY

Indenture dated as of _____________, between the Company and UMB BANK, N.A., as
trustee (herein called the "TRUSTEE", which term includes any successor Trustee
under the Indenture) and indentures supplemental thereto (collectively, the
"INDENTURE"). Under the Indenture, one or more series of debt securities may be
issued and, as used herein, the term "Securities" refers to the Securities of
this Series and any other outstanding series of Securities. Reference is hereby
made for a more complete statement of the respective rights, limitations of
rights, duties and immunities under the Indenture of the Company, the Trustee
and the Security holders and of the terms upon which the Securities are and are

date on which the principal of this Security is required to be paid, and, in the
case of timely payment thereof; no interest shall accrue for the period from and
after such Interest Payment Date or the date on which the principal of this
Security is required to be paid.

     The Company, at its option, and subject to the terms and conditions
provided in the Indenture, will be discharged from any and all obligations in
respect of the Securities (except for certain obligations including obligations
to register the transfer or exchange of Securities, replace stolen, lost or
mutilated Securities, maintain paying agencies and hold monies for payment in
trust, all as set forth in the Indenture) if the Company deposits with the
Trustee money, U.S. Government Obligations which through the payment of interest
thereon and principal thereof in

US. Government Obligations, in any event in an amount sufficient, without
reinvestment, to pay all the principal of and any premium and interest on the
Securities on the dates such payments are due in accordance with the terms of
the Securities.

     If an Event of Default shall occur and be continuing, the principal of the
Securities may be declared due and payable in the manner and with the effect
provided in the Indenture.

     The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modifications of the rights and obligations of the
Company and the rights of the Security holders under the Indenture at any time
by the Company and the Trustee with the consent of the Holders of not less than
a majority in principal amount of the outstanding Securities. Any such consent
or waiver by the Holder of this Security shall be conclusive and binding upon
such Holder and upon all future Holders of this Security and of any Security
issued upon the registration of transfer hereof or in exchange therefor in lieu
thereof whether or not notation of such consent or waiver is made upon the
Security.

     As set forth in and subject to the provisions of the Indenture, no Holder
of any Securities will have any right to institute any proceeding with respect
to the Indenture or for any remedy thereunder unless such Holder shall have
previously given to the Trustee written notice of a continuing Event of Default
with respect to such Securities, the Holders of not less than a majority in
principal amount of the outstanding Securities affected by such Event of Default
shall have made written request and offered reasonable indemnity to the Trustee
to institute such proceeding as Trustee and the Trustee shall have failed to
institute such proceeding within 60 days; provided, however, that such
limitations do not apply to a suit instituted by the Holder hereof for the
enforcement of payment of the principal of and any premium or interest on this
Security on or after the respective due dates expressed here.

     No reference herein to the Indenture and to provisions of this Security or
of the Indenture shall alter or impair the obligation of the Company, which is
absolute and unconditional, to pay the principal of and any premium and interest
on this Security at the times, places and rates and the coin or currency
prescribed in the Indenture.

     As provided in the Indenture and subject to certain limitations therein set
forth, the transfer of this Security is registrable in the Security register.

satisfactory to the Company and the Security registrar, duly executed by the
Holder hereof or the attorney in fact of such Holder duly authorized in writing,
one or more new Securities of this Series of like tenor and of authorized
denominations and for the same aggregate principal amount will be issued to the
designated transferee or transferees.

     The Securities of this Series are issuable only in registered form, without
coupons, in denominations of $1,000 and any integral multiple thereof. As
provided in the Indenture and subject to certain limitations therein set forth,

tax or other governmental charge payable in connection therewith.

     Prior to due presentment of this Security for registration of transfer, the
Company, the Trustee and any agent of the Company or the Trustee may treat the
Person in whose name this Security is registered as the owner thereof for all
purposes, whether or not this Security is overdue, and neither the Company, the
