form, the related Definitive Securities may be presented to the Trustee by

Securities, Securities with an equivalent aggregate principal amount that
were presented by the Property Trustee to the Trustee will be canceled.

         (b) The Global Securities shall represent the aggregate amount of
outstanding Securities from time to time endorsed thereon; provided, that the

unwilling or unable to continue as Depositary or the Depositary has ceased to
be a clearing agency registered under the Exchange Act or any applicable
statute or regulation, and a successor Depositary is not appointed by the
Company within 90 days after the Company receives such notice or becomes
aware of such condition, as the case may be, the Company will execute, and
the Trustee, upon receipt of a Company Order, will authenticate and make
available for delivery the Definitive Securities, in authorized
denominations, and in an aggregate principal amount equal to the principal
amount of the Global Security in exchange for such Global Security. If there
is an Event of Default, the Depositary shall have the right to exchange the
Global Securities for Definitive Securities. In addition, the Company may at
any time determine that the Securities shall no longer be represented by a
Global Security. In the event of such an Event of Default or such a
determination, the Company shall execute, and subject to SECTION 2.06, the
Trustee, upon receipt of an Officers' Certificate evidencing such
determination by the Company and a Company Order, will authenticate and make
available for delivery the Definitive Securities, in authorized
denominations, and in an aggregate principal amount equal to the principal
amount of the Global Security in exchange for such Global Security. Upon the

denominations, the Global Security shall be canceled by the Trustee. Such
Definitive Securities issued in exchange for the Global Security shall be
registered in such names and in such authorized denominations as the

consisting of twelve 30-day months and, for any period of less than a full
calendar month, the number of days lapsed in such month. In the event that
any Interest Payment Date falls on a day that is not a Business Day, then
payment of interest payable on such date will be made on the next succeeding
day which is a Business Day (and without any interest or other payment in
respect of any such delay), except that if such next succeeding Business Day
falls in the next succeeding calendar year, then such payment shall be made
on the immediately preceding Business Day, in each case with the same force
and effect as if made on the date such payment is otherwise required.

         (c) During such time as the Property Trustee is the holder of any
Securities, the Company shall pay any additional amounts on the Securities as
may be necessary in order that the amount of Distributions then due and
payable by the Trust on the outstanding Trust Securities shall not be reduced
as a result of any additional taxes, duties and other governmental charges to
which the Trust has become subject as a result of a Tax Event ("ADDITIONAL
SUMS").

         (d) Interest on any Security which is payable, and which is
punctually paid or duly provided for, on any Interest Payment Date shall be
paid to the Person is whose name that Security (or one or more Predecessor
Securities) is registered at the close of business on the record date for
such interest installment.

SECTION 2.06  TRANSFER AND EXCHANGE.

         To permit registrations of transfers and exchanges, the Company shall
execute and the Trustee shall authenticate Definitive Securities and Global
Securities in any authorized denomination and of a like aggregate principal
amount at the Security Registrar's request. All Definitive Securities and
Global Securities issued upon any registration of transfer or exchange of
Definitive Securities or Global Securities shall be the valid obligations of
the Company, evidencing the same debt, and entitled to the same benefits under
this Indenture, as the Definitive Securities or Global Securities surrendered
upon such registration of transfer or exchange.

         Every Security presented or surrendered for registration of transfer or
for exchange shall (if so required by the Company or the Trustee) be duly
endorsed or be accompanied by a written

                                       13
<Page>

instrument of transfer in a form that is satisfactory to the Company and the
Security Registrar duly executed by the holder thereof or his attorney duly
authorized in writing.

         No service charge shall be made to a holder for any registration of
transfer or exchange, but the Company may require payment of a sum sufficient
to cover any transfer tax or similar governmental charge payable in
connection therewith.

         The Company shall not be required to (i) issue, register the transfer
of or exchange Securities during a period beginning at the opening of business
15 days before the day of mailing of a notice of redemption of Securities for
redemption under ARTICLE XIV hereof and ending at the close of business on the
day of such mailing; or (ii) register the transfer of or exchange any Security
so selected for redemption in whole or in part, except the unredeemed portion
of any Security being redeemed in part.

         The transfer and exchange of beneficial interests in a Global
Security, which does not involve the issuance of a Definitive Security or the
transfer of an interest to another Global Security, shall be effected through
the Depositary (but not the Trustee) in accordance with the Indenture
(including the restrictions on transfers set forth herein) and the procedures
of the Depositary therefore. The Trustee will not have any responsibility for
the transfer and exchange of beneficial interests in such Global Security
that does not involve the issuance of a Definitive Security or the transfer
of interests to another Global Security.

         Prior to due presentment for the registration of a transfer of any
Security, the Trustee, the Company and any agent of the Trustee or the
Company may deem and treat the Person in whose name any Security is
registered as the absolute owner of such Security for the purpose of
receiving payment of principal of and premium, if any, and interest on such
Securities, neither the Trustee, nor the Company nor any agent of the Trustee
or the Company shall be affected by notice to the contrary.

SECTION 2.07  REPLACEMENT SECURITIES.

         If any mutilated Security is surrendered to the Trustee, or the
Company and the Trustee receive evidence to their satisfaction of the
destruction, loss or theft of any Security, the Company shall issue and the
Trustee shall authenticate a replacement Security if the Trustee's
requirements for replacements of Securities are met. An indemnity bond must
be supplied by the holder that is sufficient in the judgment of the Trustee
and the Company to protect the Company, the Trustee, any agent thereof or any
authenticating agent from any loss that any of them may suffer if a Security
is replaced. The Company or the Trustee may charge for its expenses in
replacing a Security.

         Every replacement Security is an obligation of the Company and shall
be entitled to all of the benefits of this Indenture equally and
proportionately with all other Securities duly issued hereunder.

SECTION 2.08  TEMPORARY SECURITIES.

         Pending the preparation of Definitive Securities, the Company may
execute, and upon Company Order the Trustee shall authenticate and make
available for delivery, temporary

                                       14
<Page>

Securities that are printed, lithographed, typewritten, mimeographed or
otherwise reproduced, in any authorized denomination, substantially of the
tenor of the Definitive Securities in lieu of which they are issued and with
such appropriate insertions, omissions, substitutions and other variations as
the officers executing such Securities may determine, as conclusively
evidenced by their execution of such Securities.

         If temporary Securities are issued, the Company shall cause
Definitive Securities to be prepared without unreasonable delay. The
Definitive Securities shall be printed, lithographed or engraved, or provided
by any combination thereof, or in any other manner permitted by the rules and
regulations of any applicable securities exchange, all as determined by the
officers executing such Definitive Securities. After the preparation of
Definitive Securities, the temporary Securities shall be exchangeable for
Definitive Securities upon surrender of the temporary Securities at the
office or agency maintained by the Company for such purpose pursuant to
SECTION 3.02 hereof, without charge to the Holder. Upon surrender for
cancellation of any one or more temporary Securities, the Company shall
execute, and the Trustee shall authenticate and make available for delivery,
in exchange therefor the same aggregate principal amount of Definitive
Securities of authorized denominations. Until so exchanged, the temporary
Securities shall in all respects be entitled to the same benefits under this
Indenture as Definitive Securities.

SECTION 2.09   CANCELLATION.

         The Company at any time may deliver Securities to the Trustee for
cancellation. The Trustee and no one else shall cancel all Securities
surrendered for registration of transfer, exchange, payment, replacement or
cancellation and shall retain or destroy canceled Securities in accordance
with its normal practices (subject to the record retention requirement of the
Exchange Act) unless the Company directs them to be returned to it. The
Company may not issue new Securities to replace Securities that have been
redeemed or paid or that have been delivered to the Trustee for cancellation.

         All Securities surrendered for payment, redemption, transfer or
exchange shall, if surrendered to any Person other than the Trustee, be
delivered to the Trustee, and any such Securities and Securities surrendered
directly to the Trustee for any such purpose shall be promptly canceled by
it. Notwithstanding any other provision of this Indenture, the Company may at
any time deliver to the Trustee for cancellation any Securities previously
authenticated and delivered hereunder which the Company may have acquired in
any manner whatsoever, and all Securities so delivered shall be promptly
canceled by the Trustee. No Securities shall be authenticated in lieu of or
in exchange for any Securities canceled as provided in this SECTION 2.9,
except as expressly permitted by this Indenture.

SECTION 2.10   DEFAULTED INTEREST.

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

                                       15
<Page>

         (a) The Company may make payment of any Defaulted Interest on
Securities to the Persons in whose names such Securities (or their respective
Predecessor Securities) are registered at the close of business on a special
record date for the payment of such Defaulted Interest, which shall be fixed
in the following manner: the Company shall notify the Trustee in writing of
the amount of Defaulted Interest proposed to be paid on each such Security
and the date of the proposed payment, and at the same time the Company shall
deposit with the Trustee an amount of money equal to the aggregate amount
proposed to be paid in respect of such Defaulted Interest or shall make
arrangements satisfactory to the Trustee for such deposit prior to the date
of the proposed payment, such money when deposited to be held in trust for
the benefit of the Persons entitled to such Defaulted Interest as in this
clause provided. Thereupon the Trustee shall fix a special record date for
the payment of such Defaulted Interest which shall not be more than 15 nor
less than 10 days prior to the date of the proposed payment and not less than
10 days after the receipt by the Trustee of the notice of the proposed
payment. The Trustee shall promptly notify the Company of such special record
date and, in the name and at the expense of the Company, shall cause notice
of the proposed payment of such Defaulted Interest and the special record
date therefor to be mailed, first class postage prepaid, to each
Securityholder at his or her address as it appears in the Security Register,
not less than 10 days prior to such special record date. Notice of the
proposed payment of such Defaulted Interest and the special record date
therefor having been mailed as aforesaid, such Defaulted Interest shall be
paid to the Persons in whose names such Securities (or their respective
Predecessor Securities) are registered on such special record date and shall
be no longer payable pursuant to the following clause (b).

         (b) The Company may make payment of any Defaulted Interest on any
Securities in any other lawful manner not inconsistent with the requirements
of any securities exchange on which such Securities may be listed, and upon
such notice as may be required by such exchange, if, after notice given by
the Company to the Trustee of the proposed payment pursuant to this clause,
such manner of payment shall be deemed practicable by the Trustee.

SECTION 2.11   CUSIP NUMBERS.

         The Company in issuing the Securities may use "CUSIP" numbers (if
then generally in use), and, if so, the Trustee shall use "CUSIP" numbers in
notices of redemption as a convenience to Securityholders; provided that any
such notice may state that no representation is made as to the correctness of
such numbers either as printed on the Securities or as contained in any
notice of a redemption and that reliance may be placed only on the other
identification numbers printed on the Securities, and any such redemption
shall not be affected by any defect in or omission of such numbers. The
Company will promptly notify the Trustee of any change in the CUSIP numbers.

                                   ARTICLE III
                       PARTICULAR COVENANTS OF THE COMPANY

SECTION 3.01   PAYMENT OF PRINCIPAL, PREMIUM AND INTEREST.

         The Company covenants and agrees for the benefit of the holders of the
Securities that it will duly and punctually pay or cause to be paid the
principal of, premium, if any, and interest on

                                       16
<Page>

the Securities at the place, at the respective times and in the manner
provided herein. The Company further covenants to pay any and all amounts,
including, without limitation, Additional Sums, as may be required pursuant
to SECTION 2.05(c) and Compounded Interest, as may be required pursuant to
SECTION 16.01.

SECTION 3.02   OFFICES FOR NOTICES AND PAYMENTS, ETC.

         So long as any of the Securities remain outstanding, the Company
will maintain in the Borough of Manhattan, The City of New York, an office or
agency where the Securities may be presented for payment, an office or agency
where the Securities may be presented for registration of transfer and for
exchange as in this Indenture provided and 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 Company will give to the Trustee written notice
of the location of any such office or agency and of any change of location
thereof. Until otherwise designated from time to time by the Company in a
notice to the Trustee, any such office or agency for all of the above
purposes shall be the Principal Office of the Trustee. In case the Company
shall fail to maintain any such office or agency in the Borough of Manhattan,
The City of New York, or shall fail to give such notice of the location or of
any change in the location thereof, presentations and demands may be made and
notices may be served at the Principal Office of the Trustee.

         In addition to any such office or agency, the Company may from time
to time designate one or more offices or agencies outside the Borough of
Manhattan, The City of New York, where the Securities may be presented for
payment, registration of transfer and for exchange in the manner provided in
this Indenture, and the Company may from time to time rescind such
designation, as the Company may deem desirable or expedient; provided,
however, that no such designation or rescission shall in any manner relieve
the Company of its obligation to maintain any such office or agency in the
Borough of Manhattan, The City of New York, for the purposes above mentioned.
The Company will give to the Trustee prompt written notice of any such
designation or rescission thereof.

SECTION 3.03   APPOINTMENTS TO FILL VACANCIES IN TRUSTEE'S OFFICE.

office of Trustee, will appoint, in the manner provided in SECTION 6.10, a

SECTION 3.04   PROVISION AS TO PAYING AGENT.

agree with the Trustee, subject to the provision of this SECTION 3.04,

                  (i) that it will hold all sums held by it as such agent for
the payment of the principal of and premium, if any, or interest on the

other obligor on the Securities) in trust for the benefit of the holders of
the Securities and comply with all provisions of the Trust Indenture Act
applicable to it as paying agent; and

the Company (or by any other obligor on the Securities) to make any payment
of the principal of and premium or interest (including Additional Sums and
Compounded Interest, if any) on the Securities when the same shall be due and
payable.

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

         (c) Anything in this SECTION 3.04 to the contrary notwithstanding,
the Company may, at any time, for the purpose of obtaining a satisfaction and
discharge with respect to the Securities hereunder, or for any other reason,
pay or cause to be paid to the Trustee all sums held in trust for such
Securities by the Trustee or any paying agent hereunder, as required by this
SECTION 3.04, such sums to be held by the Trustee upon the trusts herein
contained.

         (d) Anything in this SECTION 3.04 to the contrary notwithstanding,

SECTION 3.08   COVENANTS AS TO THE TRUST

         In the event Securities are issued to the Trust or a trustee of such
trust in connection with the issuance of Preferred Securities by the Trust, for
so long as such Preferred Securities remain outstanding, the Company (i) will
maintain 100% direct or indirect ownership of the Common Securities of the
Trust; provided, however, that any successor of the Company, permitted

                               ON EVENT OF DEFAULT

SECTION 5.01  EVENTS OF DEFAULT.

         "EVENT OF DEFAULT", wherever used herein with respect to Securities,
means any one of the following events (whatever the reason for such Event of
Default and whether it shall be voluntary or involuntary or be effected by
operation of law or pursuant to any judgment, decree or order of any court or
any order, rule or regulation of any administrative or governmental body):

         (a) default in the payment of any interest (including Compounded
Interest or Additional Sums, if any), upon any Security or any Other
Debentures when it becomes due and payable, and continuance of such default
for a period of 30 days; provided, however, that a valid extension of an
interest payment period by the Company in accordance with the terms hereof
shall not constitute a default in the payment of interest for this purpose; or

         (b) default in the payment of all or any part of the principal of
(or premium, if any, on) any Security or any Other Debentures as and when the
same shall become due and payable whether at maturity, upon redemption, by
declaration of acceleration of maturity or otherwise; or

         (c) default in the performance, or breach, of any covenant or
warranty of the Company in this Indenture (other than a covenant or warranty
a default in whose performance or whose breach is elsewhere in this Section
specifically dealt with), and continuance of such default or breach for a
period of 90 days after there has been given, by registered or certified
mail, to the Company by the Trustee or to the Company and the Trustee by the
holders of at least 33% in aggregate principal amount of the outstanding
Securities a written notice specifying such default

                                     23
<Page>

or breach and requiring it to be remedied and stating that such notice is a
"NOTICE OF DEFAULT" hereunder; or

         (d) a court having jurisdiction in the premises shall enter a decree
or order for relief in respect of the Company in an involuntary case under
any applicable bankruptcy, insolvency or other similar law now or hereafter
in effect, or appointing a receiver, liquidator, assignee, custodian,
trustee, sequestrator (or similar official) of the Company or for any
substantial part of its property, or ordering the winding-up or liquidation
of its affairs and such decree or order shall remain unstayed and in effect
for a period of 90 consecutive days; or

         (e) the Company shall commence a voluntary case under any applicable
bankruptcy, insolvency, reorganization or other similar law now or hereafter
in effect, shall consent to the entry of an order for relief in an
involuntary case under any such law, or shall consent 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 shall make any general assignment for the benefit of
creditors, or shall fail generally to pay its debts as they become due.

         If an Event of Default with respect to Securities at the time
outstanding occurs and is continuing, then in every such case the Trustee or
the holders of not less than 33% in aggregate principal amount of the
Securities then outstanding may declare the principal amount of all
Securities to be due and payable immediately, by a notice in writing to the
Company (and to the Trustee if given by the holders of the outstanding
Securities), PROVIDED that, if upon an Event of Default, the Trustee or the
holders of not less than 33% in aggregate principal amount of the Outstanding
Securities fail to declare the principal of all the Securities to be
immediately due and payable, the holders of at least 33% in aggregate
liquidation amount of the Preferred Securities then outstanding shall have
such right by a notice in writing to the Company and the Trustee, and upon
any such declaration the same shall become immediately due and payable.
Payment of principal and interest (including any Compounded Interest and
Additional Sums to the extent permitted by applicable law) on such Securities
shall remain subordinated to the extent provided in ARTICLE XV
notwithstanding that such amount shall become immediately due and payable as
herein provided. If an Event of Default specified in SECTION 5.01(d) or (e)
with respect to the Securities occurs, the principal amount of all the
Securities shall automatically, and without any declaration or other action
on the part of Trustee or any holder, become immediately due and payable.

         The foregoing provisions, however, are 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, (i) the Company shall pay or shall deposit with the Trustee a sum
sufficient to pay (A) all matured installments of interest (including
Compounded Interest and Additional Sums, if any) upon all the Securities and
the principal of and premium, if any, on any and all Securities which shall
have become due otherwise than by acceleration (with interest upon such
principal and premium, if any, and, to the extent that payment of such
interest is enforceable under applicable law, on overdue installments of
interest, at the same rate as the rate of interest specified in the
Securities to the date of such payment or deposit) and (B) such amount as
shall be sufficient to cover compensation due to the Trustee and each
predecessor Trustee, their

                                      24
<Page>

respective agents, attorneys and counsel, pursuant to SECTION 6.06, and (ii)
any and all Events of Default under the Indenture, other than the non-payment
of the principal of the Securities which shall have become due solely by such
declaration of acceleration, shall have been cured, waived or otherwise
remedied as provided herein, then, in every such case, the holders of a
majority in aggregate principal amount of the Securities then outstanding, by
written notice to the Company and to the Trustee, may rescind and annul such
declaration and its consequences, but no such waiver or rescission and
annulment shall extend to or shall affect any subsequent default or shall
impair any right consequent thereon. If the holders of a majority in
aggregate principal amount of the outstanding Securities fail to rescind and
annul such declaration and its consequences, the holders of a majority in
aggregate liquidation amount of the Preferred Securities then outstanding
shall have such right.

         In case the Trustee or any holder 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 or such
holder, then and in every such case the Company, the Trustee and the holders
of the Securities shall be restored respectively to their several positions
and rights hereunder, and all rights, remedies and powers of the Company, the
Trustee and the holders of the Securities shall continue as though no such
proceeding had been taken.

SECTION 5.02  PAYMENT OF SECURITIES ON DEFAULT; SUIT THEREFOR.

         The Company covenants that (a) in case default shall be made in the
payment of any installment of interest (including Compounded Interest and
Additional Sums, if any) upon any of the Securities as and when the same
shall become due and payable, and such default shall have continued for a
period of 30 days, or (b) in case default shall be made in the payment of the
principal of or premium, if any, on any of the Securities as and when the
same shall have become due and payable, whether at maturity of the Securities
or upon redemption or by declaration or otherwise, then, upon demand of the
Trustee, the Company will pay to the Trustee, for the benefit of the holders
of the Securities, the whole amount that then shall have become due and
payable on all such Securities for principal and premium, if any, or interest
(including Compounded Interest and Additional Sums, if any) or both, as the
case may be, with interest upon the overdue principal and premium, if any,
and (to the extent that payment of such interest is enforceable under
applicable law and, if the Securities are held by the Trust or a trustee of
such trust, without duplication of any other amounts paid by the Trust or a
trustee in respect thereof) upon the overdue installments of interest
(including Compounded Interest and Additional Sums, if any) at the rate borne
by the Securities; and, in addition thereto, such further amount as shall be
sufficient to cover the costs and expenses of collection, including a
reasonable compensation to the Trustee, its agents, attorneys and counsel,
and any other amount due to the Trustee pursuant to SECTION 6.06.

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

                                      25
<Page>

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

         If an Event of Default occurs and is continuing, the Trustee may in
its discretion proceed to protect and enforce its rights and the rights of
the holders of the Securities by such appropriate judicial proceedings as the
Trustee shall deem most effectual to protect and enforce any such rights,
whether for the specific enforcement of any covenant or agreement in this
Indenture or in aid of the exercise of any power granted herein, or to
enforce any other proper remedy.

         If an Event of Default occurs and shall be continuing as to the
Securities, the Property Trustee will have the right to declare the principal
of (premium, if any, on) and interest (including any Compounded Interest of
Additional Interest) and any other amounts payable under the Indenture to be
forthwith due and payable and to enforce the right as a creditor with respect
to the Securities.

         In case there shall be pending proceedings for the bankruptcy or for
the reorganization of the Company or any other obligor on the Securities under
Title 11, United States 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 other 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 the
provisions of this SECTION 5.02, 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 premium, if any, and interest
(including Compounded Interest and Additional Sums, if any) 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 claim for
amounts due to the Trustee pursuant to SECTION 6.06) and of the
Securityholders allowed in such judicial proceedings relative to the Company
or any other obligor on the Securities, or to the creditors or property of the
Company or such other obligor, unless prohibited by applicable law and
regulations, to vote on behalf of the holders of the Securities in any
election of a trustee or a standby trustee in arrangement, reorganization,
liquidation or other bankruptcy or insolvency proceedings or person performing
similar functions in comparable proceedings, 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; and any
receiver, assignee or trustee in bankruptcy or reorganization is hereby
authorized by each of the Securityholders to make such payments to the
Trustee, and, in the event that the Trustee shall consent to the making of
such payments directly to the Securityholders, to pay to the Trustee such
amounts as shall be sufficient to cover reasonable compensation to the
Trustee, each predecessor Trustee and their respective agents, attorneys and
counsel, and all other amounts due to the Trustee pursuant to SECTION 6.06.

         Nothing herein contained shall be construed to authorize the Trustee
to authorize or consent to or accept or adopt on behalf of any Securityholder
any plan of reorganization, arrangement, adjustment or composition affecting
the Securities or the rights of any holder

                                      26
<Page>

thereof or to authorize the Trustee to vote in respect of the claim of any
Securityholder in any such proceeding.

         All rights of action and of asserting claims 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 on 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 any proceedings brought by the Trustee (and also any proceedings
involving the interpretation of any provision of this Indenture to which the
Trustee shall be a party) the Trustee shall be held to represent all the
holders of the Securities, and it shall not be necessary to make any holders
of the Securities parties to any such proceedings.

SECTION 5.03  APPLICATION OF MONEYS COLLECTED BY TRUSTEE.

         Any moneys collected by the Trustee shall be applied in the order
following, at the date or dates fixed by the Trustee for the distribution of
such moneys, upon presentation of the Securities in respect of which moneys
have been collected, and stamping thereon the payment, if only partially
paid, and upon surrender thereof if fully paid:

         FIRST:  To the payment of costs and expenses of collection
applicable to the Securities and all other amounts due to the Trustee under
SECTION 6.06;

         SECOND:  To the payment of all Senior Indebtedness of the Company if
and to the extent required by ARTICLE XV;

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

         FOURTH:  To the Company.

SECTION 5.04  PROCEEDINGS BY SECURITYHOLDERS.

         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 and of the continuance thereof
with respect to the Securities specifying such Event of Default, as
hereinbefore provided, and unless also the holders of not less than 33% in
aggregate principal amount of the Securities then outstanding shall have made
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

                                      27
<Page>

Trustee for 60 days after its receipt of such notice, request and offer of
indemnity shall have failed to institute any such action, suit or proceeding,
it being understood and intended, and being expressly covenanted by the taker
and holder of every Security with every other taker and holder and the
Trustee, that no one or more holders of Securities shall have any right in
any manner whatever by virtue of or by availing of any provision of this
Indenture to affect, disturb or prejudice the rights of any other holder of
Securities, or to obtain or seek to obtain priority over or preference to any
other such holder, or to enforce any right under this Indenture, except in
the manner herein provided and for the equal, ratable and common benefit of
all holders of Securities.

         Notwithstanding any other provisions in this Indenture, however, the
right of any holder of any Security, which right is absolute and
unconditional, to receive payment of the principal of (premium, if any) and
interest (including Compounded Interest and Additional Sums, if any) on such
Security, on or after the same shall have become due and payable, or to
institute suit for the enforcement of any such payment, shall not be impaired
or affected without the consent of such holder and by accepting a Security
hereunder it is expressly understood, intended and covenanted by the taker
and holder of every Security with every other such taker and holder and the
Trustee, that no one or more holders of Securities shall have any right in
any manner whatsoever by virtue or by availing of any provision of this
Indenture to affect, disturb or prejudice the rights of the holders of any
other Securities, or to obtain or seek to obtain priority over or preference
to any other such holder, or to enforce any right under this Indenture,
except in the manner herein provided and for the equal, ratable and common
benefit of all holders of Securities. For the protection and enforcement of
the provisions of this Section, each and every Securityholder and the Trustee
shall be entitled to such relief as can be given either at law or in equity.

         The Company and the Trustee acknowledge that pursuant to the
Declaration, the holders of Preferred Securities are entitled, in the
circumstances and subject to the limitations set forth therein, to commence a
Direct Action with respect to any Event of Default under this Indenture and
the Securities. Notwithstanding any payment made to such holder of Preferred
Securities by the Company in connection with a Direct Action, the Company
shall remain obligated to pay the principal of or interest on the Securities
held by the Trust or the Property Trustee. In connection with any such Direct
Action, the Company will be subrogated to the rights of any holder of the
Preferred Securities to the extent of any payment made by the Company to such
holder of Preferred Securities as a result of such Direct Action. Except as
set forth in this Article, the other holders of Preferred Securities shall
have no right to exercise directly any other rights or remedy available to the
Holders of or in respect of, the Securities unless an event of default under
the Declaration shall have occurred.

SECTION 5.05  PROCEEDINGS BY TRUSTEE.

         In case an Event of Default occurs with respect to Securities and is
continuing, 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 in this

                                      28
<Page>

Indenture, or to enforce any other legal or equitable right vested in the
Trustee by this Indenture or by law.

SECTION 5.06  REMEDIES CUMULATIVE AND CONTINUING.

         All powers and remedies given by this ARTICLE V to the Trustee or to
the Securityholders shall, to the extent permitted by law, be deemed
cumulative and not exclusive of any other powers and remedies available to
the Trustee or the holders of the Securities, by judicial proceedings or
otherwise, to enforce the performance or observance of the covenants and
agreements contained in this Indenture or otherwise established with respect
to the Securities, and no delay or omission of the Trustee or of any holder
of any of the Securities to exercise any right or power accruing upon any
Event of Default occurring and continuing as aforesaid shall impair any such
right or power, or shall be construed to be a waiver of any such default or
an acquiescence therein; and, subject to the provisions of SECTION 5.04,
every power and remedy given by this ARTICLE V or by law to the Trustee or to
the Securityholders may be exercised from time to time, and as often as shall
be deemed expedient, by the Trustee or by the Securityholders.

SECTION 5.07  DIRECTION OF PROCEEDINGS AND WAIVER OF DEFAULTS BY MAJORITY OF
SECURITYHOLDERS.

         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, however, that such direction shall not be in conflict with any rule
or law or with this Indenture and, (subject to the provisions of SECTION
6.01) the Trustee shall have the right to decline to follow any such
direction if the Trustee shall determine that the action so directed would be
unjustly prejudicial to the holders not taking part in such direction or 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 and/or Responsible Officers shall determine that the
action or proceedings so directed would involve the Trustee in personal
liability. Prior to any declaration accelerating the maturity of the
Securities, the holders of a majority in aggregate principal amount of the
Securities at the time outstanding may on behalf of the holders of all of the
Securities waive any past default or Event of Default and its consequences
except a default (a) in the payment of principal of or premium, if any, or
interest (including Compounded Interest and Additional Sums, if any) on any
of the Securities or (b) in respect of covenants or provisions hereof which
cannot be modified or amended without the consent of the holder of each
Security affected; provided, however, that if the Securities are held by the
Property Trustee, such waiver or modification to such waiver shall not be
effective until the holders of a majority in aggregate liquidation amount of
Trust Securities shall have consented to such waiver or modification to such
waiver; provided further, that if the consent of the holder of each
outstanding Security is required, such waiver shall not be effective until
each holder of the Preferred Securities shall have consented to such waiver.
Upon any such waiver, the default covered thereby shall be deemed to be cured
for all purposes of this Indenture and the Company, the Trustee and the
holders of the Securities shall be restored to their former positions and
rights hereunder, respectively; but no such waiver shall extend to any
subsequent or other default or impair any right consequent thereon. Whenever
any default or Event of Default hereunder shall

                                      29
<Page>

have been waived as permitted by this SECTION 5.07, 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 5.08  NOTICE OF DEFAULTS.

         The Trustee shall, within 90 days after the occurrence of a
default with respect to the Securities known to a Responsible Officer of the
Trustee, mail to all Securityholders, as the names and addresses of such
holders appear upon the Security Register, notice of all defaults known to
the Trustee, unless such defaults shall have been cured before the giving of
such notice (the term "DEFAULTS" for the purpose of this SECTION 5.08 being
hereby defined to be the events specified in clauses (a), (b), (c), (d) and
(e) of SECTION 5.01, not including periods of grace, if any, provided for
therein, and irrespective of the giving of written notice specified in clause
(c) of SECTION 5.01); and provided that, except in the case of default in the
payment of the principal of or premium, if any, or interest (including
Compounded Interest or Additional Sums, if any) on any of the Securities, the
Trustee shall be protected in withholding such notice if and so long as the
board of directors, the executive committee, or a trust committee of
directors and/or Responsible Officers of the Trustee in good faith determines
that the withholding of such notice is in the interests of the
Securityholders; and provided further, that in the case of any default of the
character specified in SECTION 5.01(c) no such notice to Securityholders
shall be given until at least 60 days after the occurrence thereof but shall
be given within 90 days after such occurrence.

SECTION 5.09  UNDERTAKING TO PAY COSTS.

         All parties to this Indenture agree, and each holder of any Security
by his acceptance thereof shall be deemed to have agreed, that any court may
in its discretion require, in any suit for the enforcement of any right or
remedy under this Indenture, or in any suit against the Trustee for any
action taken or omitted by it as Trustee, the filing by any party litigant in
such suit of an undertaking to pay the costs of such suit, and that such
court may in its discretion assess reasonable costs, including reasonable
attorneys' fees and expenses, against any party litigant in such suit, having
due regard to the merits and good faith of the claims or defenses made by
such party litigant; but the provisions of this SECTION 5.09 shall not apply
to any suit instituted by the Company or the Trustee; to any suit instituted
by any Securityholder, or group of Securityholders, holding in the aggregate
more than 10% in aggregate principal amount of the Securities outstanding; or
to any suit instituted by any Securityholder for the enforcement of the
payment of the principal of (or premium, if any) or interest (including
Compounded Interest and Additional Sums, if any) on any Security against the
Company on or after the same shall have become due and payable.

                                      30

SECTION 5.10  WAIVER OF STAY OR EXTENSION LAWS.

         The Company covenants (to the extent that it may lawfully do so)
that it will not any time insist upon, or plead, or in any manner whatsoever
claim or take the benefit or advantage of, any stay or extension law wherever
enacted, now or at any time hereafter in force which may affect the covenants
or the performance of this Indenture; and the Company (to the extent that it
may lawfully do so) hereby expressly waives all benefit or advantage of any
such law and covenants that it will not hinder, delay or impede the execution
of any power herein granted to the Trustee, but will suffer and permit the
execution of every such power as though no such law had been enacted.

                                   ARTICLE VI
                             CONCERNING THE TRUSTEE

SECTION 6.01  DUTIES AND RESPONSIBILITIES OF TRUSTEE.

         With respect to the holders of the Securities issued hereunder, the
Trustee, prior to the occurrence of an Event of Default and after the curing
or waiving 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. In case 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 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.

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

         (a)  prior to the occurrence of an Event of Default and after the
curing or waiving of all Events of Default which may have occurred,

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

                  (ii) in the absence of bad faith on the part of the
Trustee, the Trustee may 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;

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

                                      31
<Page>

         (c) the Trustee shall not be liable with respect to any action taken
or omitted to be taken by it in good faith, in accordance with the direction
of the Securityholders pursuant to SECTION 5.07, 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.

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

SECTION 6.02  RELIANCE ON DOCUMENTS, OPINIONS, ETC.

         Except as otherwise provided in SECTION 6.01:

         (a) the Trustee may conclusively rely and shall be protected in acting
or refraining from acting upon any resolution, certificate, statement,
instrument, opinion, report, notice, request, consent, order, bond, note,
debenture 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 may be sufficiently evidenced by an Officers' Certificate (unless
other evidence in respect thereof be 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;

         (c) the Trustee may consult with counsel of its selection and any
advice or Opinion of Counsel shall be full and complete authorization and
protection in respect of any action taken or suffered 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 Securityholders, pursuant to the provisions of this
Indenture, unless such Securityholders shall have offered to the Trustee
security or indemnity satisfactory to it against the costs, expenses and
liabilities which may be incurred therein or thereby;

         (e) the Trustee shall not be liable for any action taken or omitted
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; nothing
contained herein shall, however, relieve the Trustee of the obligation, upon
the occurrence of an Event of Default (that has not been cured or waived), to
exercise such of the rights and powers vested in it by this Indenture, and to
use the same degree of care and skill in their exercise, as a prudent man
would exercise or use under the circumstances in the conduct of his own
affairs;

         (f) the Trustee shall not be bound to make any investigation into
the facts or matters stated in any resolution, certificate, statement,
instrument, opinion, report, notice, request, consent, order, approval, bond,
debenture, coupon or other paper or document, unless requested

                                      32
<Page>

in writing to do so by the holders of a majority in aggregate principal
amount of the outstanding Securities; provided, however, that if the payment
within a reasonable time to the Trustee of the costs, expenses or liabilities
likely to be incurred by it in the making of such investigation is, in the
opinion of the Trustee, not reasonably assured to the Trustee by the security
afforded to it by the terms of this Indenture, the Trustee may require
reasonable indemnity against such expense or liability as a condition to so
proceeding;

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

         (h) the Trustee shall not be charged with knowledge of any Default
or Event of Default with respect to the Securities unless (1) such default is
a default under SECTIONS 5.01(a) (other than a default with respect to the
payment of Compounded Interest or Additional Sums) and 5.01(b) of the
Indenture, (2) a Responsible Officer shall have actual knowledge of such
Default or Event of Default or (3) written notice of such Default or Event of
Default shall have been given to the Trustee by the Company or any other
obligor on the Securities or by any holder of the Securities;

         (i) the Trustee shall not be liable for any action taken, suffered
or omitted by it in good faith, without negligence or willful misconduct and
believed by it to be authorized or within the discretion or rights or powers
conferred upon it by this Indenture;

         (j) the Trustee shall not be deemed to have notice of any Default or
Event of Default unless a Responsible Officer of the Trustee has actual
knowledge thereof or unless written notice of any event which is in fact such
a default is received by the Trustee at the Corporate Trust Office of the
Trustee, and such notice references the Securities and this Indenture;

         (k) the rights, privileges, protections, immunities and benefits given
to the Trustee, including, without limitation, its right to be indemnified, are
extended to, and shall be enforceable by, the Trustee in each of its capacities
hereunder, and each agent, custodian and other Person employed to act
hereunder; and

         (l) the Trustee may request that the Company deliver an Officers'
Certificate setting forth the names of individuals and/or titles of officers
authorized at such time to take specified actions pursuant to this Indenture,
which Officers' Certificate may be signed by any person authorized to sign an
Officers' Certificate, including any person specified as so authorized in any
such certificate previously delivered and not superseded.

SECTION 6.03  NO RESPONSIBILITY FOR RECITALS, ETC.

         The recitals contained herein and in the Securities (except in the
certificate of authentication of the Trustee or the Authenticating Agent)
shall be taken as the statements of the Company and the Trustee and the
Authenticating Agent assume no responsibility for the correctness of the
same. The Trustee and the Authenticating Agent make no representations as to
the validity or sufficiency of this Indenture or of the Securities. The
Trustee and the Authenticating Agent 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 or the Authenticating
Agent in conformity with the provisions of this Indenture.

SECTION 6.04  TRUSTEE, AUTHENTICATING AGENT, PAYING AGENTS, TRANSFER AGENTS OR
REGISTRAR MAY OWN SECURITIES.

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

SECTION 6.05  MONEYS TO BE HELD IN TRUST.

         Subject to the provisions of SECTION 11.04, all moneys received by
the Trustee or any paying agent shall, until used or applied as herein
provided, be held in trust for the purpose for which they were received, but
need not be segregated from other funds except to the extent

                                      33
<Page>

required by law. The Trustee and any paying agent shall be under no liability
for interest on any money received by it hereunder except as otherwise agreed
in writing with the Company. So long as no Event of Default shall have
occurred and be continuing, all interest allowed on any such moneys shall be
paid from time to time upon the written order of the Company, signed by the
Chairman of the Board of Directors, the President, a Vice President, the
Treasurer or an Assistant Treasurer of the Company.

SECTION 6.06  COMPENSATION AND EXPENSES OF TRUSTEE.

         The Company, as issuer of Securities under this Indenture, covenants
and agrees to pay to the Trustee from time to time, and the Trustee shall be
entitled to, such compensation as shall be agreed to in writing between the
Company and the Trustee (which shall not be limited by any provision of law in
regard to the compensation of a trustee of an express trust), and the Company
will pay or reimburse the Trustee upon its request for all reasonable expenses,
disbursements and advances incurred or made by the Trustee in accordance with
any of the provisions of this Indenture (including the reasonable compensation
and the expenses and disbursements of its counsel and of all persons not
regularly in its employ) except any such expense, disbursement or advance as
may arise from its negligence or bad faith. The Company also covenants to
indemnify each of the Trustee or any predecessor Trustee (and its officers,
agents, directors and employees) for, and to hold it harmless against, any and
all loss, damage, claim, liability or expense including taxes (other than taxes
based on the income of the Trustee) incurred without negligence or bad faith on
the part of the Trustee and arising out of or in connection with the acceptance
or administration of this trust, including the costs and expenses of defending
itself against any claim (whether asserted by the Company, a Holder or any
other Person) of liability in the premises. The obligations of the Company
under this SECTION 6.06 to compensate and indemnify the Trustee and to pay or
reimburse the Trustee for expenses, disbursements and advances shall constitute
additional indebtedness hereunder. Such additional indebtedness shall be
secured by a lien prior to that of the Securities upon all property and funds
held or collected by the Trustee as such, except funds held in trust for the
benefit of the holders of particular Securities.

         When the Trustee incurs expenses or renders services in connection
with an Event of Default specified in SECTION 5.01(d) or SECTION 5.01(e), the
expenses (including the reasonable charges and expenses of its counsel) and
the compensation for the services are intended to constitute expenses of
administration under any applicable federal or state bankruptcy, insolvency
or other similar law.

         The provisions of this Section shall survive the resignation or
removal of the Trustee and the defeasance or other termination of this
Indenture.

SECTION 6.07  OFFICERS' CERTIFICATE AS EVIDENCE.

         Except as otherwise provided in SECTIONS 6.01 and 6.02, whenever in
the administration of the provisions of this Indenture the Trustee shall deem
it necessary or desirable that a matter be proved or established prior to
taking or omitting 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 certificate, in the

                                     34
<Page>

absence of negligence or bad faith on the part of the Trustee, shall be full
warrant to the Trustee for any action taken or omitted by it under the
provisions of this Indenture upon the faith thereof.

SECTION 6.08  CONFLICTING INTEREST OF TRUSTEE.

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

SECTION 6.09  ELIGIBILITY OF TRUSTEE.

         The Trustee hereunder shall at all times be a corporation organized
and doing business under the laws of the United States of America or any
state or territory thereof or of the District of Columbia or a corporation or
other Person permitted to act as trustee by the Commission authorized under
such laws to exercise corporate trust powers, having a combined capital and
surplus of at least 50 million U.S. dollars ($50,000,000) and subject to
supervision or examination by federal, state, territorial, or District of
Columbia authority. If such corporation publishes reports of condition at
least annually, pursuant to law or to the requirements of the aforesaid
supervising or examining authority, then for the purposes of this SECTION
6.09 the combined capital and surplus of such corporation shall be deemed to
be its combined capital and surplus as set forth in its most recent report of
condition so published.

         The Company may not, nor may any Person directly or indirectly
controlling, controlled by, or under common control with the Company, serve
as Trustee.

         In case at any time the Trustee shall cease to be eligible in
accordance with the provisions of this SECTION 6.09, the Trustee shall resign
immediately in the manner and with the effect specified in SECTION 6.10.

SECTION 6.10  RESIGNATION OR REMOVAL OF TRUSTEE.

         (a) The Trustee, or any trustee or trustees hereafter appointed, may
at any time resign by giving written notice of such resignation to the Company
and by mailing notice thereof to the holders of the Securities at their
addresses as they shall appear on the Security register. Upon receiving such
notice of resignation, the Company shall promptly appoint a successor trustee
or trustees by written instrument, in duplicate, one copy of which instrument
shall be delivered to the resigning Trustee and one copy to the successor
trustee. If no successor trustee shall have been so appointed and have accepted
appointment within 60 days after the mailing of such notice of resignation to
the affected Securityholders, the resigning Trustee may petition, at the
expense of the Company, any court of competent jurisdiction for the appointment
of a successor trustee, or any Securityholder who has been a bona fide holder
of a Security for at least six months may, subject to the provisions of SECTION
5.09, on behalf of himself and all others similarly situated, petition any such
court for the appointment of a successor trustee. Such court may thereupon,
after such notice, if any, as it may deem proper and prescribe, appoint a
successor trustee.

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

                                      35
<Page>

                  (i) the Trustee shall fail to comply with the provisions of
SECTION 6.08 after written request therefor by the Company or by any
Securityholder who has been a bona fide holder of a Security or Securities
for at least six months, or

                  (ii) the Trustee shall cease to be eligible in accordance
with the provisions of SECTION 6.09 and shall fail to resign after written
request therefor by the Company or by any such Securityholder, or

                  (iii) the Trustee shall become incapable of acting, or
shall be adjudged a bankrupt or insolvent, or a receiver of the Trustee or of
its property shall be appointed, or any public officer shall take charge or
control of the Trustee or of its property or affairs for the purpose of
rehabilitation, conservation or liquidation, then, in any such case, the
Company may remove the Trustee and appoint a successor trustee by written
instrument, in duplicate, one copy of which instrument shall be delivered to
the Trustee so removed and one copy to the successor trustee, or, subject to
the provisions of SECTION 5.09, any Securityholder who has been a bona fide
holder of a Security for at least six months may, on behalf of himself and
all others similarly situated, petition any court of competent jurisdiction
for the removal of the Trustee and the appointment of a successor trustee.
Such court may thereupon, after such notice, if any, as it may deem proper,
remove the Trustee and appoint a successor trustee.

         (c) The holders of a majority in aggregate principal amount of the
Securities at the time outstanding may at any time remove the Trustee and
nominate a successor trustee, which shall be deemed appointed as successor
trustee unless within 10 days after such nomination the Company objects
thereto or if no successor trustee shall have been so appointed and shall
have accepted appointment within 30 days after such removal, in which case
the Trustee so removed or any Securityholder, upon the terms and conditions
and otherwise as in subsection (a) of this SECTION 6.10 provided, may
petition any court of competent jurisdiction for an appointment of a
successor trustee. Upon receiving such notice of resignation, the Company
shall promptly appoint a successor trustee or trustees by written instrument,
in duplicate, one copy of which instrument shall be delivered to the resigning
Trustee and one copy to the successor trustee.

         (d) Any resignation or removal of the Trustee and appointment of a
successor trustee pursuant to any of the provisions of this SECTION 6.10
shall become effective only upon acceptance of appointment by the successor
trustee as provided in SECTION 6.11.

SECTION 6.11  ACCEPTANCE BY SUCCESSOR TRUSTEE.

         Any successor trustee appointed as provided in SECTION 6.10 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 retiring 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 the provisions of SECTION 6.06, execute and
deliver an instrument transferring to such successor trustee all the rights
and powers of the trustee so ceasing to act and shall duly assign, transfer
and deliver to such successor trustee all property and money held by such
retiring trustee thereunder. Upon request of any such successor trustee, the
Company shall execute any and all instruments in writing for more fully and
certainly vesting in and confirming

                                      36
<Page>

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 the
provisions of SECTION 6.06.

         No successor trustee shall accept appointment as provided in this
SECTION 6.11 unless at the time of such acceptance such successor trustee
shall be qualified under the provisions of Section 6.08 and eligible under
the provisions of SECTION 6.09.

         Upon acceptance of appointment by a successor trustee as provided in
this SECTION 6.11, the Company shall mail notice of the succession of such
trustee hereunder to the holders of Securities at their addresses as they
shall appear on the Security register. If the Company fails to mail such
notice within 10 days after the acceptance of appointment by the successor
trustee, the successor trustee shall cause such notice to be mailed at the
expense of the Company.

SECTION 6.12  SUCCESSION BY MERGER, ETC.

         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 corporations shall be otherwise
qualified and eligible under this Article.

         In case at the time such successor to the Trustee shall succeed to
the trusts created by this Indenture any 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 the Securities or this Indenture
elsewhere provides that the certificate of the Trustee shall have; provided,
however, 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 6.13  LIMITATION ON RIGHTS OF TRUSTEE AS A CREDITOR.

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

SECTION 6.14  AUTHENTICATING AGENTS.

         There may be one or more Authenticating Agents appointed by the
Trustee upon the request of the Company with power to act on its behalf and
subject to its direction in the authentication and delivery of Securities
issued upon exchange or transfer thereof as fully to all intents and purposes
as though any such Authenticating Agent had been expressly authorized to

                                      37
<Page>

authenticate and deliver Securities; provided, that the Trustee shall have no
liability to the Company for any acts or omissions of the Authenticating
Agent with respect to the authentication and delivery of Securities. Any such
Authenticating Agent shall at all times be a corporation organized and doing
business under the laws of the United States or of any state or territory
thereof or of the District of Columbia authorized under such laws to act as
Authenticating Agent, having a combined capital and surplus of at least
$50,000,000 and being subject to supervision or examination by federal,
state, territorial or District of Columbia authority. If such corporation
publishes reports of condition at least annually pursuant to law or the
requirements of such authority, then for the purposes of this SECTION 6.14
the combined capital and surplus of such corporation shall be deemed to be
its combined capital and surplus as set forth in its most recent report of
condition so published. If at any time an Authenticating Agent shall cease to
be eligible in accordance with the provisions of this Section, it shall
resign immediately in the manner and with the effect herein specified in this
Section.

         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, consolidation or conversion to which any Authenticating Agent
shall be a party, or any corporation succeeding to all or substantially all of
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 6.14 without the
execution or filing of any paper or any further act on the part of the parties
hereto or such Authenticating Agent.

         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 6.14, the Trustee may, and upon the request of the Company shall,
promptly appoint a successor Authenticating Agent eligible under this SECTION
6.14, shall give written notice of such appointment to the Company and shall
mail notice of such appointment to all Securityholders as the names and
addresses of such holders appear on the Security Register. Any successor
Authenticating Agent upon acceptance of its appointment hereunder shall
become vested with all rights, powers, duties and responsibilities of its
predecessor hereunder, with like effect as if originally named as
Authenticating Agent herein.

         The Company, as borrower, agrees to pay to any Authenticating Agent
from time to time reasonable compensation for its services. Any
Authenticating Agent shall have no responsibility or liability for any action
taken by it as such in accordance with the directions of the Trustee.

                                   ARTICLE VII
                         CONCERNING THE SECURITYHOLDERS

SECTION 7.01  ACTION BY SECURITYHOLDERS.

         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 (including the making of any demand or request, the giving of any
notice, consent or waiver or the taking of any other action)

                                      38
<Page>

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
Securityholders in person or by agent or proxy appointed in writing, or (b)
by the record of such holders of Securities voting in favor thereof at any
meeting of such Securityholders duly called and held in accordance with the
provisions of ARTICLE VIII, or (c) by a combination of such instrument or
instruments and any such record of such a meeting of such Securityholders.

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

SECTION 7.02  PROOF OF EXECUTION BY SECURITYHOLDERS.

         Subject to the provisions of SECTION 6.01, 6.02 and 8.05, proof of
the execution of any instrument by a Securityholder or his agent or proxy
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 Security Register or by a certificate of the Security registrar. The
Trustee may require such additional proof of any matter referred to in this
Section as it shall deem necessary.

         The record of any Securityholders' meeting shall be proved in the
manner provided in SECTION 8.06.

SECTION 7.03  WHO ARE DEEMED ABSOLUTE OWNERS.

         Prior to due presentment for registration of transfer of any
Security, the Company, the Trustee, any Authenticating Agent, any paying
agent, any transfer agent and any Security registrar may deem the person in
whose name such Security shall be registered upon the Security Register to
be, and may treat him 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 of and premium, if any, and (subject to SECTION
2.05) interest on such Security and for all other purposes; and neither the
Company nor the Trustee nor any Authenticating Agent nor any paying agent nor
any transfer agent nor any Security registrar shall be affected by any notice
to the contrary. All such payments so made to any holder for the time being
or upon his order shall be

                                      39
<Page>

valid, and, to the extent of the sum or sums so paid, effectual to satisfy
and discharge the liability for moneys payable upon any such Security.

SECTION 7.04  SECURITIES OWNED BY COMPANY DEEMED NOT OUTSTANDING.

         In determining whether the holders of the requisite aggregate
principal amount of Securities have concurred in any direction, consent,
notice or waiver under this Indenture, Securities which are owned by the
Company or any other obligor on the Securities or any Affiliate of the
Company (other than the Trust) or any other obligor on the Securities shall
be disregarded and deemed not to be outstanding for the 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 a Responsible Officer of the Trustee actually
knows are so owned shall be so disregarded. Securities so owned which have
been pledged in good faith may be regarded as outstanding for the purposes of
this SECTION 7.04 if the pledgee shall establish to the satisfaction of the
Trustee the pledgee's right to vote such Securities and that the pledgee is
not the Company or any such other obligor or Affiliate of 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 7.05  REVOCATION OF CONSENTS; FUTURE HOLDERS BOUND.

         At any time prior to (but not after) the evidencing to the Trustee,
as provided in SECTION 7.01, of 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 (or
any Security issued in whole or in part in exchange or substitution
therefor), subject to SECTION 7.01, the serial number of which is shown by
the evidence to be included in the Securities the holders of which have
consented to such action may, by filing written notice with the Trustee at
its principal office and upon proof of holding as provided in SECTION 7.02,
revoke such action so far as concerns such Security (or so far as concerns
the principal amount represented by any exchanged or substituted Security).
Except as aforesaid any such action taken by the holder of any Security shall
be conclusive and binding upon such holder and upon all future holders and
owners of such Security, and of any Security issued in exchange or
substitution therefor, irrespective of whether or not any notation in regard
thereto is made upon such Security or any Security issued in exchange or
substitution therefor.

                                  ARTICLE VIII
                            SECURITYHOLDERS' MEETINGS

         A meeting of Securityholders may be called at any time and from time
to time pursuant to the provisions of this ARTICLE VIII for any of the
following purposes:

         (a) to give any notice to the Company or to the Trustee, or to give
any directions to the Trustee, or to consent to the waiving of any default
hereunder and its consequences, or to take any other action authorized to be
taken by Securityholders pursuant to any of the provisions of ARTICLE V;

                                      40
<Page>

         (b)  to remove the Trustee and nominate a successor trustee pursuant
to the provisions of ARTICLE VI;

         (c)  to consent to the execution of an indenture or indentures
supplemental hereto pursuant to the provisions of SECTION 9.02; or

         (d) to take any other action authorized to be taken by or on behalf
of the holders of any specified aggregate principal amount of such Securities
under any other provision of this Indenture or under applicable law.

SECTION 8.02  CALL OF MEETINGS BY TRUSTEE.

         The Trustee may at any time call a meeting of Securityholders to
take any action specified in SECTION 8.01, to be held at such time and at
such place in the Borough of Manhattan, The City of New York, as the Trustee
shall determine. Notice of every meeting of the Securityholders, setting
forth the time and the place of such meeting and in general terms the action
proposed to be taken at such meeting, shall be mailed to holders of
Securities at their addresses as they shall appear on the Securities
Register. Such notice shall be mailed not less than 20 nor more than 180 days
prior to the date fixed for the meeting.

SECTION 8.03  CALL OF MEETINGS BY COMPANY OR SECURITYHOLDERS.

         In case at any time the Company pursuant to a resolution of the
Board of Directors, or the holders of at least 10% in aggregate principal
amount of the Securities then outstanding, shall have requested the Trustee
to call a meeting of Securityholders, by written request setting forth in
reasonable detail the action proposed to be taken at the meeting, and the
Trustee shall not have mailed the notice of such meeting within 20 days after
receipt of such request, then the Company or such Securityholders may

further appropriate agreements and stipulations which may be therein
contained and to accept the conveyance, transfer and assignment of any
property thereunder, but the Trustee shall not be obligated to, but may in

discretion, but shall not be obligated to, enter into such supplemental
indenture.

SECTION 13.09 TABLE OF CONTENTS, HEADINGS, ETC.

         The table of contents and the titles and headings of the articles and

SECTION 13.10 EXECUTION IN COUNTERPARTS.

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

SECTION 13.11 SEPARABILITY.

         In case any one or more of the provisions contained in this Indenture
or in the Securities shall for any reason be held to be invalid, illegal or
unenforceable in any respect, such invalidity,

                                      51
<Page>

illegality or unenforceability shall not affect any other provisions of this
Indenture or of the Securities, but this Indenture and the Securities shall
be construed as if such invalid or illegal or unenforceable provision had
never been contained herein or therein.

SECTION 13.12 ASSIGNMENT.

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

SECTION 13.13 ACKNOWLEDGMENT OF RIGHTS.

         The Company acknowledges that, with respect to any Securities held by
the Trust or a trustee of such trust, if the Property Trustee of such Trust
fails to enforce its rights under this Indenture as the holder of the Securities
held as the assets of the Trust any holder of Preferred Securities may, to the
full extent permitted by law, institute legal proceedings directly against the
Company to enforce such Property Trustee's rights under this Indenture without
first instituting any legal proceedings against such Property Trustee or any
other person or entity. Notwithstanding the foregoing, if an Event of Default
has occurred and is continuing and such event is attributable to the failure of
the Company to pay principal of or premium, if any, or interest on the
Securities when due, the Company acknowledges that a holder of Preferred
Securities may directly institute a proceeding for enforcement of payment to
such holder of the principal of or premium, if any, or interest on the
Securities having a principal amount equal to the aggregate liquidation amount
of the Preferred Securities of such holder on or after the respective due date
specified in the Securities.

                            REDEMPTION OF SECURITIES

SECTION 14.01 SPECIAL EVENT REDEMPTION.

         If, at any time, a Special Event has occurred and is continuing then,
notwithstanding SECTION 14.02(a), the Company shall have the right but not the
obligation, at any time within 90 days following the occurrence of such Special
Event, upon (i) not less than 45 days' written notice to the Trustee and (ii)
not less than 30 days' nor more than 60 days' written notice to the
Securityholders, to redeem the Securities, in whole (but not in part), at the
Special Event Redemption Price. Following a Special Event, if the Company wishes
to exercise its right of redemption pursuant to this SECTION 14.01, the Company
shall take such action as is necessary to promptly determine the Special Event
Redemption Price, including without limitation the appointment by the Company of
a Reference Treasury Dealer. The Company shall provide the Trustee with written
notice of the Special Event Redemption Price promptly after the calculation
thereof, which notice shall include any calculation made by the Reference
Treasury Dealer in connection with the determination of the Special Event
Redemption Price.

                                      52
<Page>

The Company shall deposit with the Trustee an amount sufficient to pay the
Special Event Redemption Price by 10:00 a.m., New York City time, on the date
such Special Event Redemption Price is to be paid.

SECTION 14.02 OPTIONAL REDEMPTION BY COMPANY.

         Subject to the provisions of this ARTICLE XIV, the Company shall have
the right to redeem the Securities, in whole or in part, from time to time, at a
redemption price equal to the Optional Redemption Price.

         If the Securities are only partially redeemed pursuant to this SECTION
14.02, the Securities to be redeemed shall be selected on a pro rata basis not
more than 60 days prior to the date fixed for redemption from the outstanding
Securities not previously called for redemption; provided, however, that with
respect to Securityholders that would be required to hold Securities with an
aggregate principal amount of less than $100,000 but more than an aggregate
principal amount of zero as a result of such pro rata redemption, the Company
shall redeem Securities of each such Securityholder so that after such
redemption such Securityholder shall hold Securities either with an aggregate
principal amount of at least $100,000 or such Securityholder no longer holds
any Securities and shall use such method (including, without limitation, by
lot) as the Company shall deem fair and appropriate; provided, further, that
any such proration may be made on the basis of the aggregate principal amount
of Securities held by each Securityholder and may be made by making such
adjustments as the Company deems fair and appropriate in order that only
Securities in denominations of $1,000 or integral multiples thereof shall be
redeemed. The Company shall deposit with the Trustee an amount sufficient to
pay the Optional Redemption Price by 10:00 a.m., New York City time, on the
date such Optional Redemption Price is to be paid.

SECTION 14.03 NO SINKING FUND.

         The Securities are not entitled to the benefit of any sinking fund.

SECTION 14.04 NOTICE OF REDEMPTION; SELECTION OF SECURITIES.

         In case the Company shall desire to exercise the right to redeem
all, or, as the case may be, any part of the Securities in accordance with
their terms, it shall fix a date for redemption and shall mail a notice of
such redemption at least 30 and not more than 60 days prior to the date fixed
for redemption to the holders of Securities so to be redeemed as a whole or
in part at their last addresses as the same appear on the Security Register.
Such mailing shall be by first class mail. The notice if mailed in the manner
herein provided shall be conclusively presumed to have been duly given,
whether or not the holder receives such notice. In any case, failure to give
such notice by mail or any defect in the 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.

         Each such notice of redemption shall specify the CUSIP number of the
Securities to be redeemed, the date fixed for redemption, the redemption
price at which the Securities are to be redeemed (or the method by which such
redemption price is to be calculated), the place or places

                                       53
<Page>

of payment that payment will be made upon presentation and surrender of the
Securities, that interest accrued to the date fixed for redemption will be
paid as specified in said notice, and that on and after said date interest
thereon or on the portions thereof to be redeemed will cease to accrue. If
less than all the Securities are to be redeemed the notice of redemption
shall specify the numbers of the Securities to be redeemed. In case any
Security is to be redeemed in part only, the notice of redemption shall state
the portion of the principal amount thereof to be redeemed and shall state
that on and after the date fixed for redemption, upon surrender of such
Security, a new Security or Securities in principal amount equal to the
unredeemed portion thereof will be issued.

         By 10:00 a.m. New York City time on the redemption date specified in
the notice of redemption given as provided in this Section, the Company will
deposit with the Trustee or with one or more paying agents an amount of money
sufficient to redeem on the redemption date all the Securities so called for
redemption at the appropriate Redemption Price, together with accrued
interest to the date fixed for redemption.

         The Company will give the Trustee notice not less than 45 days prior
to the redemption date as to the aggregate principal amount of Securities to
be redeemed and the Trustee shall select, in such manner as in its sole
discretion it shall deem appropriate and fair, the Securities or portions
thereof (in integral multiples of $1,000, except as otherwise set forth in
the applicable form of Security) to be redeemed.

SECTION 14.05 PAYMENT OF SECURITIES CALLED FOR REDEMPTION.

         If notice of redemption has been given as provided in SECTION 14.04,
the Securities or portions of Securities with respect to which such notice
has been given shall become due and payable on the date and at the place or
places stated in such notice at the applicable Redemption Price, together
with interest accrued to the date fixed for redemption (subject to the rights
of holders of Securities on the close of business on a regular record date in
respect of an Interest Payment Date occurring on or prior to the redemption
date), and on and after said date (unless the Company shall default in the
payment of such Securities at the Redemption Price, together with interest
accrued to said date) interest (including Compounded Interest and Additional
Sums, if any) on the Securities or portions of Securities so called for
redemption shall cease to accrue. On presentation and surrender of such
Securities at a place of payment specified in said notice, the said
Securities or the specified portions thereof shall be paid and redeemed by
the Company at the applicable Redemption Price, together with interest
(including Compounded Interest and Additional Sums, if any) accrued thereon
to the date fixed for redemption (subject to the rights of holders of
Securities on the close of business on a regular record date in respect of an
Interest Payment Date occurring on or prior to the redemption date).

         Upon presentation of any Security redeemed in part only, the Company
shall execute and the Trustee shall authenticate and make available for
delivery to the holder thereof, at the expense of the Company, a new Security
or Securities of authorized denominations, in principal amount equal to the
unredeemed portion of the Security so presented.

                                   ARTICLE XV
                           SUBORDINATION OF SECURITIES

SECTION 15.01 AGREEMENT TO SUBORDINATE.

         The Company covenants and agrees, and each holder of Securities
issued hereunder likewise covenants and agrees, that the Securities shall be
issued subject to the provisions of this ARTICLE XV; and each holder of a
Security, whether upon original issue or upon transfer or assignment thereof,
accepts and agrees to be bound by such provisions.

         The payment by the Company of the principal of, premium, if any, and
interest (including Compounded Interest and Additional Sums, if any) on all
Securities issued hereunder shall, to the extent and in the manner
hereinafter set forth, be subordinated and junior in right of payment to all
Senior Indebtedness, whether outstanding at the date of this Indenture or
thereafter incurred.

         No provision of this ARTICLE XV shall prevent the occurrence of any
Default or Event of Default hereunder.

SECTION 15.02 DEFAULT ON SENIOR INDEBTEDNESS.

         In the event and during the continuation of any default by the
Company in the payment of principal, premium, interest or any other payment
due on any Senior Indebtedness, or in the event that the maturity of any
Senior Indebtedness has been accelerated because of a default, then, in
either case, no payment shall be made by the Company with respect to the
principal (including redemption payments) of or premium, if any, or interest
on the Securities until such default shall have been cured or waived in
writing or shall have ceased to exist or such Senior Indebtedness shall have
been discharged or paid in full.

         In the event of the acceleration of the maturity of the Securities,
then no payment shall be made by the Company with respect to the principal
(including redemption payments) of or premium, if any, or interest on the
Securities until the holders of all Senior Indebtedness outstanding at the
time of such acceleration shall receive payment in full of such Senior
Indebtedness (including any amounts due upon acceleration).

         In the event that, notwithstanding the foregoing, any payment shall
be received by the Trustee or any Securityholder when such payment is
prohibited by the preceding paragraphs of this SECTION 15.02, such payment
shall be held in trust for the benefit of, and shall be paid over or
delivered to, the holders of Senior Indebtedness or their respective
representatives, or to the trustee or trustees under any indenture pursuant
to which any of such Senior Indebtedness may have been issued, as their
respective interests may appear.

SECTION 15.03 LIQUIDATION; DISSOLUTION; BANKRUPTCY.

         Upon any payment by the Company or distribution of assets of the
Company of any kind or character, whether in cash, property or securities, to
creditors upon any dissolution or winding-up or liquidation or reorganization
of the Company, whether voluntary or involuntary or in bankruptcy,
insolvency, receivership or other proceedings, all Senior Indebtedness of the

                                      55
<Page>

Company shall first be paid in full, or payment thereof provided for in money
in accordance with its terms, before any payment is made by the Company on
account of the principal (and premium, if any) or interest (including
Compounded Interest and Additional Sums, if any) on the Securities; and upon
any such dissolution or winding-up or liquidation or reorganization, any
payment by the Company, or distribution of assets of the Company of any kind
or character, whether in cash, property or securities, to which the
Securityholders or the Trustee would be entitled to receive from the Company,
except for the provisions of this ARTICLE XV, shall be paid by the Company or
by any receiver, trustee in bankruptcy, liquidating trustee, agent or other
Person making such payment or distribution, or by the Securityholders or by
the Trustee under the Indenture if received by them or it, directly to the
holders of Senior Indebtedness of the Company (pro rata to such holders on
the basis of the respective amounts of Senior Indebtedness held by such
holders, as calculated by the Company) or their representative or
representatives, or to the trustee or trustees under any indenture pursuant
to which any instruments evidencing such Senior Indebtedness may have been
issued, as their respective interests may appear, to the extent necessary to
pay all such Senior Indebtedness in full, in money in accordance with its
terms, after giving effect to any concurrent payment or distribution to or
for the holders of such Senior Indebtedness, before any payment or
distribution is made to the Securityholders or to the Trustee.

         In the event that, notwithstanding the foregoing, any payment or
distribution of assets of the Company of any kind or character, whether in
cash, property or securities, prohibited by the foregoing, shall be received
by the Trustee or any Securityholder before all Senior Indebtedness is paid
in full, or provision is made for such payment in money in accordance with
its terms, such payment or distribution shall be held in trust for the
benefit of and shall be paid over or delivered to the holders of such Senior
Indebtedness or their representative or representatives, or to the trustee or
trustees under any indenture pursuant to which any instruments evidencing
such Senior Indebtedness may have been issued, as their respective interests
may appear, as calculated by the Company, for application to the payment of
all Senior Indebtedness remaining unpaid to the extent necessary to pay all
such Senior Indebtedness in full in money in accordance with its terms, after
giving effect to any concurrent payment or distribution to or for the benefit
of the holders of such Senior Indebtedness.

         For purposes of this ARTICLE XV only, the words "assets of the
Company of any kind or character, whether cash, property or securities" shall
not be deemed to include shares of stock of the Company as reorganized or
readjusted, or securities of the Company or any other corporation provided
for by a plan of reorganization or readjustment, the payment of which is
subordinated at least to the extent provided in this ARTICLE XV with respect
to the Securities to the payment of Senior Indebtedness that may at the time
be outstanding; provided that (i) such Senior Indebtedness is assumed by the
new corporation, if any, resulting from any such reorganization or
readjustment, and (ii) the rights of the holders of such Senior Indebtedness
are not, without the consent of such holders, altered by such reorganization
or readjustment. The consolidation of the Company with, or the merger of the
Company into, another Person or the liquidation or dissolution of the Company
following the sale, conveyance, transfer or lease of its property as an
entirety, or substantially as an entirety, to another Person upon the terms
and conditions provided for in ARTICLE X of this Indenture shall not be
deemed a dissolution, winding-up, liquidation or reorganization for the
purposes of this SECTION 15.03 if such other Person shall, as a part of such
consolidation, merger, sale, conveyance, transfer or lease, comply with the
conditions stated in

                                      56
<Page>

ARTICLE X of this Indenture. Nothing in SECTION 15.02 or in this SECTION
15.03 shall apply to claims of, or payments to, the Trustee under or pursuant
to SECTION 6.06 of this Indenture.

         Nothing contained in this ARTICLE XV or elsewhere in this Indenture
or in the Securities is intended to or shall impair, as between the Company,
its creditors other than the holders of Senior Indebtedness of the Company,
and the holders of the Securities, the obligation of the Company, which is
absolute and unconditional, to pay to the holders of the Securities the
principal of (and premium, if any) and interest (including Compounded
Interest and Additional Sums, if any) on the Securities as and when the same
shall become due and payable in accordance with their terms, or is intended
to or shall affect the relative rights of the holders of the Securities and
creditors of the Company, as the case may be, other than the holders of
Senior Indebtedness of the Company, as the case may be, nor shall anything
herein or therein prevent the occurrence of an Event of Default under ARTICLE
V or prevent the Trustee or the holder of any Security from exercising all
remedies otherwise permitted by applicable law upon the occurrence of a
Default or an Event of Default under the Indenture, subject to the rights, if
any, under this ARTICLE XV of the holders of such Senior Indebtedness in
respect of cash, property or securities of the Company, as the case may be,
received upon the exercise of any such remedy.

SECTION 15.04 SUBROGATION.

         Subject to the payment in full of all Senior Indebtedness, the rights
of the Securityholders shall be subrogated to the rights of the holders of such
Senior Indebtedness to receive payments or distributions of cash, property or
securities of the Company, as the case may be, applicable to such Senior
Indebtedness until the principal of (and premium, if any) and interest on the
Securities shall be paid in full; and, for the purposes of such subrogation, no
payments or distributions to the holders of such Senior Indebtedness of any
cash, property or securities to which the Securityholders or the Trustee would
be entitled except for the provisions of this ARTICLE XV, and no payment over
pursuant to the provisions of this ARTICLE XV to or for the benefit of the
holders of such Senior Indebtedness by Securityholders or the Trustee, shall, as
between the Company, its creditors other than holders of Senior Indebtedness of
the Company, and the holders of the Securities, be deemed to be a payment by the
Company to or on account of such Senior Indebtedness. It is understood that the
provisions of this ARTICLE XV are and are intended solely for the purposes of
defining the relative rights of the holders of the Securities, on the one hand,
and the holders of such Senior Indebtedness on the other hand.

SECTION 15.05 TRUSTEE TO EFFECTUATE SUBORDINATION.

         Each Securityholder by such Securityholder's acceptance thereof
authorizes and directs the Trustee on such Securityholder's behalf to take such
action as may be necessary or appropriate to effectuate the subordination
provided in this ARTICLE XV and appoints the Trustee such Securityholder's
attorney-in-fact for any and all such purposes.

SECTION 15.06 NOTICE BY THE COMPANY.

         The Company shall give prompt written notice to a Responsible Officer
of the Trustee of any fact known to the Company that would prohibit the making
of any payment of monies to or by the Trustee in respect of the Securities
pursuant to the provisions of this ARTICLE XV.

                                      57
<Page>

Notwithstanding the provisions of this ARTICLE XV or any other provision of
this Indenture, the Trustee shall not be charged with knowledge of the
existence of any facts that would prohibit the making of any payment of
monies to or by the Trustee in respect of the Securities pursuant to the
provisions of this ARTICLE XV, unless and until a Responsible Officer of the
Trustee shall have received written notice thereof from the Company or a
holder or holders of Senior Indebtedness or from any trustee therefor; and
before the receipt of any such written notice, the Trustee, subject to the
provisions of ARTICLE VI of this Indenture, shall be entitled in all respects
to assume that no such facts exist; provided, however, that if the Trustee
shall not have received the notice provided for in this SECTION 15.06 at
least two Business Days prior to the date upon which by the terms hereof any
money may become payable for any purpose (including, without limitation, the
payment of the principal of (or premium, if any) or interest (including
Compounded Interest and Additional Sums, if any) on any Security, then,
anything herein contained to the contrary notwithstanding, the Trustee shall
have full power and authority to receive such money and to apply the same to
the purposes for which they were received, and shall not be affected by any
notice to the contrary that may be received by it within two Business Days
prior to such date.

         The Trustee, subject to the provisions of ARTICLE VI of this
Indenture, shall be entitled to conclusively rely on the delivery to it of a
written notice by a Person representing himself to be a holder of Senior
Indebtedness of the Company (or a trustee on behalf of such holder), as the
case may be, to establish that such notice has been given by a holder of such
Senior Indebtedness or a trustee on behalf of any such holder or holders. In
the event that the Trustee determines in good faith that further evidence is
required with respect to the right of any Person as a holder of such Senior
Indebtedness to participate in any payment or distribution pursuant to this
ARTICLE XV, the Trustee may request such Person to furnish evidence to the
reasonable satisfaction of the Trustee as to the amount of such Senior
Indebtedness held by such Person, the extent to which such Person is entitled
to participate in such payment or distribution and any other facts pertinent
to the rights of such Person under this ARTICLE XV, and, if such evidence is
not furnished, the Trustee may defer any payment to such Person pending
judicial determination as to the right of such Person to receive such payment.

         Upon any payment or distribution of assets of the Company referred
to in this ARTICLE XV, the Trustee and the Securityholders shall be entitled
to rely upon any order or decree entered by any court of competent
jurisdiction in which such insolvency, bankruptcy, receivership, liquidation,
reorganization, dissolution, winding up or similar case or proceeding is
pending, or a certificate of the trustee in bankruptcy, liquidating trustee,
custodian, receiver, assignee for the benefit of creditors, agent or other
person making such payment or distribution, delivered to the Trustee or to
the Securityholders, for the purpose of ascertaining the persons entitled to
participate in such payment or distribution, the holders of Senior
Indebtedness and other indebtedness of the Company, the amount thereof or
payable thereon, the amount or amounts paid or distributed thereon and all
other facts pertinent thereto or to this ARTICLE XV.

SECTION 15.07 RIGHTS OF THE TRUSTEE; HOLDERS OF SENIOR INDEBTEDNESS.

         The Trustee in its individual capacity shall be entitled to all the
rights set forth in this ARTICLE XV in respect of any Senior Indebtedness at
any time held by it, to the same extent as any other holder of Senior
Indebtedness, and nothing in this Indenture shall deprive the Trustee of any
of its rights as such holder.

                                      58
<Page>

         With respect to the holders of Senior Indebtedness of the Company,
the Trustee undertakes to perform or to observe only such of its covenants and
obligations as are specifically set forth in this ARTICLE XV, and no implied
covenants or obligations with respect to the holders of such Senior
Indebtedness shall be read into this Indenture against the Trustee. The
Trustee shall not be deemed to owe any fiduciary duty to the holders of such
Senior Indebtedness and, subject to the provisions of ARTICLE VI of this
Indenture, the Trustee shall not be liable to any holder of such Senior
Indebtedness if it shall pay over or deliver to Securityholders, the Company
or any other Person money or assets to which any holder of such Senior
Indebtedness shall be entitled by virtue of this ARTICLE XV or otherwise.

         Nothing in this ARTICLE XV shall apply to claims of, or payments to,
the Trustee under or pursuant to SECTION 6.06.

SECTION 15.08 SUBORDINATION MAY NOT BE IMPAIRED.

         No right of any present or future holder of any Senior Indebtedness
of the Company to enforce subordination as herein provided shall at any time
in any way be prejudiced or impaired by any act or failure to act on the part
of the Company, as the case may be, or by any act or failure to act, in good
faith, by any such holder, or by any noncompliance by the Company, as the
case may be, with the terms, provisions and covenants of this Indenture,
regardless of any knowledge thereof that any such holder may have or
otherwise be charged with.

         Without in any way limiting the generality of the foregoing
paragraph, the holders of Senior Indebtedness of the Company may, at any time
and from time to time, without the consent of or notice to the Trustee or the
Securityholders, without incurring responsibility to the Securityholders and
without impairing or releasing the subordination provided in this ARTICLE XV
or the obligations hereunder of the holders of the Securities to the holders
of such Senior Indebtedness, do any one or more of the following: (i) change
the manner, place or terms of payment or extend the time of payment of, or
renew or alter, such Senior Indebtedness, or otherwise amend or supplement in
any manner such Senior Indebtedness or any instrument evidencing the same or
any agreement under which such Senior Indebtedness is outstanding; (ii) sell,
exchange, release or otherwise deal with any property pledged, mortgaged or
otherwise securing such Senior Indebtedness; (iii) release any Person liable
in any manner for the collection of such Senior Indebtedness; and (iv)
exercise or refrain from exercising any rights against the Company, as the
case may be, and any other Person.

SECTION 15.09 ARTICLE APPLICABLE TO PAYING AGENTS.

         In case at any time any paying agent other than the Trustee shall
have been appointed by the Company and be then acting hereunder, the term
"Trustee" as used in this Article shall in such case (unless the context
otherwise requires) be construed as extending to and including such paying
agent within its meaning as fully for all intents and purposes as if such
paying agent were named in this Article in addition to or in place of the
Trustee.

                                      59

SECTION 15.10 TRUST MONEYS NOT SUBORDINATED.

         Notwithstanding anything contained herein to the contrary, payments
from money or the proceeds of U.S. Government Obligations held in trust under
SECTION 11.02 of this Indenture by the Trustee for the payment of principal of
and interest on the Securities shall not be subordinated to the prior payment of
any Senior Indebtedness or subject to the restrictions set forth in this ARTICLE
XV, and none of the Securityholders shall be obligated to pay over any such

                                   ARTICLE XVI
                      EXTENSION OF INTEREST PAYMENT PERIOD

SECTION 16.01 EXTENSION OF INTEREST PAYMENT PERIOD.

         So long as no Event of Default has occurred and is continuing, the
Company shall have the right, at any time and from time to time during the term
of the Securities, to defer payments of interest by extending the interest
payment period of such Securities for a period not exceeding 10 consecutive
semi-annual periods, including the first such semi-annual period during such
extension period (the "EXTENDED INTEREST PAYMENT PERIOD"), during which Extended
Interest Payment Period no interest shall be due and payable; provided that no
Extended Interest Payment Period shall end on a date other than an Interest
Payment Date or extend beyond the Maturity Date. To the extent permitted by
applicable law, interest, the payment of which has been deferred because of the
extension of the interest payment period pursuant to this SECTION 16.01, will
bear interest thereon at the Coupon Rate compounded semi-annually for each
semi-annual period of the Extended Interest Payment Period ("COMPOUNDED
INTEREST"). At the end of the Extended Interest Payment Period, the Company
shall pay all interest accrued and unpaid on the Securities, including any
Additional Sums and Compounded Interest (together, "DEFERRED INTEREST") that
shall be payable to the holders of the Securities in whose names the Securities
are registered in the Security Register on the first record date preceding the
end of the Extended Interest Payment Period. Before the termination of any
Extended Interest Payment Period, the Company may further defer payments of
interest by further extending such period; provided that such period, together
with all such previous and further extensions within such Extended Interest
Payment Period, shall not exceed 10 consecutive semi-annual periods, including
the first such semi-annual period during such Extended Interest Payment Period,
end on a date other than an Interest Payment Date or extend beyond the Maturity
Date of the Securities. Upon the termination of any Extended Interest Payment
Period and the payment of all Deferred Interest then due, the Company may
commence a new Extended Interest Payment Period, subject to the foregoing
requirements. No interest shall be due and payable during an Extended Interest
Payment Period, except at the end thereof, but the Company may prepay at any
time all or any portion of the interest accrued during an Extended Interest
Payment Period.

SECTION 16.02 NOTICE OF EXTENSION.

         (a) If the Property Trustee is the only registered holder of the
Securities at the time the Company selects an Extended Interest Payment Period,
the Company shall give written notice to the Administrative Trustees, the
Property Trustee and the Trustee of its selection of such

                                       60

Extended Interest Payment Period five Business Days before the earlier of (i)
the next succeeding date on which Distributions on the Trust Securities
issued by the Trust are payable, or (ii) the date the Trust is required to
give notice of the record date, or the date such Distributions are payable,
to any national securities exchange or to holders of the Preferred Securities
issued by the Trust, but in any event at least five Business Days before such
record date.

         (b) If the Property Trustee is not the only holder of the Securities at
the time the Company selects an Extended Interest Payment Period, the Company
shall give the holders of the Securities and the Trustee written notice of its
selection of such Extended Interest Payment Period at least 10 Business Days
before the earlier of (i) the next succeeding Interest Payment Date, or (ii) the
date the Company is required to give notice of the record or payment date of
such interest payment to any national securities exchange.

         (c) The semi-annual period in which any notice is given pursuant to
paragraphs (a) or (b) of this SECTION 16.02 shall be counted as one of the 10
semi-annual periods permitted in the maximum Extended Interest Payment Period
permitted under SECTION 16.01.

                            DUE ______________, ____

         Illinois Power Company, an Illinois corporation (the "Company", which
term includes any successor Person under the Indenture hereinafter referred to),
for value received, hereby promises to pay to BNY Midwest Trust Company, as
Property Trustee for Illinois Power Financing II or registered assigns, the
principal sum of __________________ DOLLARS ($__________) on _________, ___ (the
"Maturity Date"), unless previously redeemed, and to pay interest on the
outstanding principal amount hereof from ___________, ____, or from the most
recent interest payment date (each such date, an "Interest Payment Date") to
which interest has been paid or duly provided for, semi-annually (subject to
deferral as set forth herein) in arrears on __________ and __________ of each
year, commencing ______________, ____, at the rate of ____% per annum until the
principal hereof shall have become due and payable, and on any overdue principal
and premium, if any, and (without duplication and to the extent that payment of
such interest is enforceable under applicable law) on any overdue installment of
interest at the same rate per annum compounded semi-annually. The amount of
interest payable on any Interest Payment Date shall be computed on the basis of
a 360-day year of twelve 30-day months and, for any period less than a full
calendar month, the number of days elapsed in such month. In the event that any
date on which the principal of (or premium, if any) or interest on this Security
is payable is not a Business Day, then the payment payable on such date will be
made on the next succeeding day that is a Business Day (and without any interest
or other payment in respect of any such delay), except that if such next
succeeding Business Day falls in the next calendar year, then such payment shall
be made on the immediately preceding Business Day, in each case with the same
force and effect as if made on the date such payment is otherwise required.
Pursuant to the Indenture, in certain circumstances the Company will be required
to pay Additional Sums and Compounded Interest (each as defined in the
Indenture) with respect to this Security.

         The interest installment so payable, and punctually paid or duly
provided for, on any Interest Payment Date will, as provided in the Indenture,
be paid to the Person in whose name this Security (or one or more Predecessor
Securities, as defined in said Indenture) is registered at the close of business
on the regular record date for such interest installment, which shall be at the
close of business on the _____ day of the month preceding the month in which the
relevant interest payment date falls. Any such interest installment not
punctually paid or duly provided for shall forthwith cease to be payable to the
holders on such regular record date and may be paid to the Person in whose name
this Security (or one or more Predecessor Securities) is registered at the close
of business on a special record date to be fixed by the Trustee for the payment
of such defaulted interest, notice whereof shall be given to the holders of
Securities not less than 10 days prior to such special record date, or may be
paid at any time in any other lawful manner not inconsistent with the
requirements of any securities exchange on which the Securities may be listed,
and upon such notice as may be required by such exchange, all as more fully
provided in the Indenture.

                                       63
<Page>

         The principal of (and premium, if any) and interest (including
Compounded Interest and Additional Sums, if any) on this Security shall be
payable at the office or agency of the Trustee maintained for that purpose in
any coin or currency of the United States of America that at the time of payment
is legal tender for payment of public and private debts; provided, however,
that, payment of interest may be made at the option of the Company by (i) check
mailed to the holder at such address as shall appear in the Security Register or
(ii) by transfer to an account maintained by the Person entitled thereto;
provided that proper written transfer instructions have been received by the
relevant record date. Notwithstanding the foregoing, so long as the Holder of
this Security is the Property Trustee, the payment of the principal of (and
premium, if any) and interest (including Compounded Interest and Additional
Sums, if any) on this Security will be made at such place and to such account as
may be designated by the Property Trustee.

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

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

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

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

                          (FORM OF REVERSE OF SECURITY)

         This Security is one of the Securities of the Company (herein
sometimes referred to as the "SECURITIES"), specified in the Indenture, all
issued or to be issued under and pursuant to an Indenture, dated as of
___________, ___ (the "INDENTURE"), duly executed and delivered between the
Company and BNY Midwest Trust Company, as Trustee (the "TRUSTEE"), to which
Indenture reference is hereby made for a description of the rights, limitations
of rights, obligations, duties and immunities thereunder of the Trustee, the
Company and the holders of the Securities.

         Upon the occurrence and continuation of a Special Event at any time,
the Company shall have the right, at any time within 90 days following the
occurrence of such Special Event, to redeem this Security in whole (but not in
part) at the Special Event Redemption Price. "SPECIAL EVENT REDEMPTION PRICE"
shall mean, with respect to any redemption of the Securities following a Special
Event, an amount in cash equal to 100% of the principal amount of the Securities
to be redeemed plus accrued and unpaid interest thereon (including Additional
Sums and Compounded Interest, if any) to the date of redemption.

         In addition, the Company shall have the right to redeem this Security,
in whole or in part, at any time (an "OPTIONAL REDEMPTION"), at a redemption
price (the "OPTIONAL REDEMPTION PRICE") equal to the greater of (i) 100% of the
principal amount of the Securities to be so redeemed plus accrued and unpaid
interest thereon (including Additional Sums, if any) to the date of redemption
and (ii) the sum of the present values of the remaining scheduled payments of
principal of the Securities to be so redeemed and interest thereon (including
Additional Sums, if any) discounted to the date of redemption, on a semi-annual
basis (assuming a 360-day year consisting of twelve 30-day months), at the
Treasury Rate (as defined herein) plus ___ basis points plus accrued interest
thereon to the date of redemption.

         "COMPARABLE TREASURY ISSUE" means the United States Treasury security
selected by the Reference Treasury Dealer as having a maturity comparable to the
remaining term of the Securities to be redeemed that would be utilized, at the
time of selection and in accordance with customary financial practice, in
pricing new issues of corporate debt securities of comparable maturity to the
remaining term of such Securities.

         "TREASURY RATE" means, with respect to any redemption date, the rate
per annum equal to the semiannual equivalent yield to maturity of the Comparable
Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as
a percentage of its principal amount) equal to the Comparable Treasury Price for
such redemption date.

         "COMPARABLE TREASURY PRICE" means, with respect to any redemption date,
(i) the average of the bid and asked prices for the Comparable Treasury Issue
(expressed in each case as a percentage of its principal amount) on the third
business day preceding such redemption date, as set forth in the daily
statistical release (or any successor release) published by the Federal Reserve
Bank of New York and designated "Composite 3:30 p.m. Quotations for U.S.
Government Securities" or (ii) if such release (or any successor release) is not
published or does not contain such prices on such business day, the average of
the Reference Treasury Dealer Quotations for such redemption date.

                                       66
<Page>

         "REFERENCE TREASURY DEALER QUOTATIONS" means, with respect to the
Reference Treasury Dealer and any redemption date, the average, as determined by
the Debenture Trustee, of the bid and asked prices for the Comparable Treasury
Issue (expressed in each case as a percentage of its principal amount) quoted in
writing to the Debenture Trustee by the Reference Treasury Dealer at 5:00 p.m.,
New York City time, on the third business day preceding such redemption date.

         "REFERENCE TREASURY DEALER" means ________________ and its successors;
provided however, that if _______________ shall cease to be a primary U.S.
Government securities dealer in New York City (a "PRIMARY TREASURY DEALER"), the
Company shall substitute therefor another Primary Treasury Dealer.

         The Optional Redemption Price or the Special Event Redemption Price,
as the case requires, shall be deposited with the Trustee by 10:00 a.m., New
York City time, on the date such Redemption Price is to be paid. Any
redemption pursuant to this paragraph will be made upon not less than 30 days
nor more than 60 days notice. If the Securities are only partially redeemed by
the Company pursuant to an Optional Redemption, the particular Securities to
be redeemed shall be selected on a pro rata basis not more than 60 days prior
to the date fixed for redemption from the outstanding Securities not
previously called for redemption; provided, however, that with respect to
Securityholders that would be required to hold Securities with an aggregate
principal amount of less than $100,000 but more than an aggregate principal
amount of zero as a result of such pro rata redemption, the Company shall
redeem Securities of each such Securityholder so that after such redemption
such Securityholder shall hold Securities either with an aggregate principal
amount of at least $100,000 or such Securityholder no longer holds any
Securities and shall use such method (including, without limitation, by lot)
as the Company shall deem fair and appropriate; provided, further, that any
such proration may be made on the basis of the aggregate principal amount of
Securities held by each Securityholder thereof and may be made by making such
adjustments as the Company deems fair and appropriate in order that only
Securities in denominations of $1,000 or integral multiples thereof shall be
redeemed.

         In the event of redemption of this Security in part only, a new
Security or Securities for the unredeemed portion hereof will be issued in the
name of the holder hereof upon the cancellation hereof.

         In case an Event of Default, as defined in the Indenture, shall have
occurred and be continuing, the principal of all of the Securities may be
declared, and upon such declaration shall become, due and payable, in the
manner, with the effect and subject to the conditions provided in the Indenture.

         The Indenture contains provisions for satisfaction and discharge of the
entire indebtedness of this Security upon compliance by the Company with certain
conditions set forth in the Indenture.

         The Indenture contains provisions permitting the Company and the
Trustee, with the consent of the holders of a majority in aggregate principal
amount of the Securities at the time

                                       67
<Page>

outstanding, as defined in the Indenture, to execute supplemental indentures
for the purpose of adding any provisions to or changing in any manner or
eliminating any of the provisions of the Indenture or of modifying in any
manner the rights of the holders of the Securities; provided, however, that no
such supplemental indenture shall become effective without the consent of the
holders of a majority in liquidation amount of Trust Securities (if the
Securities are held by the Property Trustee) or shall, without the consent of
each holder of Securities then outstanding and affected thereby, (i) change
the Maturity Date of any Securities, or reduce the principal amount thereof,
or reduce any amount payable on redemption thereof, or reduce the rate or
extend the time of payment of interest thereon (subject to ARTICLE XVI of the
Indenture), or make the principal of, or interest or premium on, the
Securities payable in any coin or currency other than U.S. dollars, or impair
or affect the right of any holder of Securities to institute suit for the
payment thereof, or (ii) reduce the aforesaid percentage of Securities, the
holders of which are required to consent to any such supplemental indenture.
The Indenture also contains provisions permitting the holders of a majority in
aggregate principal amount of the Securities at the time outstanding affected
thereby, on behalf of all of the holders of the Securities, to waive any past
default in the performance of any of the covenants contained in the Indenture,
or established pursuant to the Indenture, and its consequences, subject to the
consent of the holders of a majority in liquidation amount of Trust Securities
(if the Securities are held by the Property Trustee), except a default in the
payment of the principal of or premium, if any, or interest on any of the
Securities or a default in respect of any covenant or provision under which
the Indenture cannot be modified or amended without the consent of each holder
of Securities then outstanding. Any such consent or waiver by the holder of
this Security (unless revoked as provided in the Indenture) shall be
conclusive and binding upon such Holder and upon all future holders and owners
of this Security and of any Security issued in exchange herefor or in place
hereof (whether by registration of transfer or otherwise), irrespective of
whether or not any notation of such consent or waiver is made upon this
Security.

         No reference herein to the Indenture and no provision 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 premium, if any, and
interest (including Compounded Interest and Additional Sums, if any) on this
Security at the time and place and at the rate and in the money herein
prescribed.

         So long as no Event of Default shall have occurred and be continuing,
the Company shall have the right, at any time and from time to time during the
term of the Securities, to defer payments of interest by extending the interest
payment period of such Securities for a period not exceeding 10 consecutive
semi-annual periods, including the first such semi-annual period during such
extension period, and not extending beyond the Maturity Date of the Securities
(an "EXTENDED INTEREST PAYMENT PERIOD") or ending on a date other than an
Interest Payment Date, at the end of which period the Company shall pay all
interest then accrued and unpaid (together with interest thereon at the rate
specified for the Securities to the extent that payment of such interest is
enforceable under applicable law). Before the termination of any such Extended
Interest Payment Period, the Company may further defer payments of interest by
further extending such Extended Interest Payment Period; provided that such
Extended Interest Payment Period, together with all such previous and further
extensions within such Extended Interest Payment Period, (i) shall not exceed 10
consecutive semi-annual periods, including the first semi-annual period during
such Extended Interest Payment Period, (ii) shall not end on any date other than
an Interest Payment Date, and (iii) shall not extend beyond the Maturity Date of
the Securities. Upon the termination of any such Extended Interest Payment
Period and the payment

                                       68
<Page>

of all accrued and unpaid interest and any additional amounts then due, the
Company may commence a new Extended Interest Payment Period, subject to the
foregoing requirements.

         The Company has agreed that it will not (i) declare or pay any
dividends or distributions on, or redeem, purchase, acquire, or make a
liquidation payment with respect to, any of the Company's capital stock
(which includes common and preferred stock) (other than (a) dividends or
distributions in shares of, or options, warrants or rights to subscribe for
or purchase shares of, Common Stock, (b) any declaration of a dividend in
connection with the implementation of a stockholder's rights plan, or the
issuance of stock under any such plan in the future, or the redemption or
repurchase of any such rights pursuant thereto, (c) as a result of a
reclassification of the Company's capital stock or the exchange or the
conversion of one class or series of the Company's capital stock, for another
class or series of the Company's capital stock, (d) the purchase of
fractional interests in shares of the Company's capital stock pursuant to the
exchange or conversion of such capital stock or the security being exchanged
or converted, and (e) purchases of Common Stock related to the issuance of
Common Stock or rights under any of the Company's benefit plans for its
directors, officers or employees or any of the Company's dividend
reinvestment plans) or (ii) make any payment of principal, interest or
premium, if any, on or repay or repurchase or redeem any debt securities of
the Company that rank PARI PASSU with or junior in right of payment to the
Securities or (iii) make any guarantee payments with respect to any guarantee
(other than payments under the Preferred Securities Guarantee) by the Company
of the debt securities of any Subsidiary of the Company if such guarantee
ranks PARI PASSU or junior in right of payment to the Securities if at such
time (1) there shall have occurred any event of which the Company has actual
knowledge that (a) with the giving of notice or the lapse of time, or both,
would be, an Event of Default and (b) in respect of which the Company shall
not have taken reasonable steps to cure, (2) an Event of Default hereunder
shall have occurred and be continuing, (3) if the Securities are held by the
Property Trustee, the Company shall be in default with respect to its payment
obligations under the Preferred Securities Guarantee or (4) the Company shall
have given notice of its election of the exercise of its right to extend the
interest payment period and any such extension shall be continuing.

         Subject to the receipt by the Company of an opinion of counsel to the
effect that such distribution will not be a taxable event to holders of
Preferred Securities, the Company will have the right at any time to liquidate
the Trust and cause the Securities to be distributed to the holders of the Trust
Securities in liquidation of the Trust.

         The Securities are issuable only in registered form without coupons in
denominations of $1,000.00 and any integral multiple thereof. As provided in the
Indenture and subject to the transfer restrictions limitations as may be
contained herein and therein from time to time, this Security is transferable by
the holder hereof on the Security Register of the Company, upon surrender of
this Security for registration of transfer at the office or agency of the
Company in The City and State of New York accompanied by a written instrument or
instruments of transfer in form satisfactory to the Company or the Trustee duly
executed by the holder hereof or his attorney duly authorized in writing, and
thereupon one or more new Securities of authorized denominations and for the
same aggregate principal amount and series will be issued to the designated
transferee or transferees. No service charge will be made for any such
registration of transfer, but the Company may require payment of a sum
sufficient to cover any tax or other governmental charge payable in relation
thereto.

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

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

         All terms used in this Security that are defined in the Indenture shall
have the meanings assigned to them in the Indenture.

         THE INDENTURE AND THE SECURITIES SHALL BE DEEMED TO BE A CONTRACT MADE
UNDER THE LAWS OF THE STATE OF NEW YORK, AND FOR ALL PURPOSES SHALL BE GOVERNED
BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, WITHOUT
REGARD TO CONFLICTS OF LAWS PRINCIPLES THEREOF.

Guarantee.

         NOW, THEREFORE, in consideration of the purchase by each Holder, which

consequences. Upon such waiver, any such Event of Default shall cease to exist,

any right consequent thereon.

SECTION 2.7 EVENT OF DEFAULT; NOTICE.

after the occurrence of an Event of Default with respect to this Preferred
Securities Guarantee actually known to a Responsible Officer, mail by first

unless such defaults have been cured before the giving of such notice, provided,
that, except in the case of default in the payment of any Guarantee Payment, the
Preferred Securities Guarantee Trustee shall be protected in withholding such
notice if and so long as the board of directors, the executive committee, or a
trust committee of directors and/or a Responsible Officer in good faith
determines that the withholding of such notice is in the interests of the
Holders.

         (b) The Preferred Securities Guarantee Trustee shall not be deemed to
have knowledge of any Event of Default unless the Preferred Securities Guarantee
Trustee shall have received

                                       6

written notice from the Guarantor, or a Responsible Officer charged with the

and as trustee of an express trust, against the Guarantor for the whole amount
of any Guarantee, payments remaining unpaid and (b) file such proofs of claim
and other papers or documents as may be necessary or advisable in order to have
its claims and those of the Holders of the Preferred Securities allowed in any

                            POWERS, DUTIES AND RIGHTS
                    OF PREFERRED SECURITIES GUARANTEE TRUSTEE

SECTION 3.1 POWERS AND DUTIES OF THE PREFERRED SECURITIES GUARANTEE TRUSTEE.

         (a) This Preferred Securities Guarantee shall be held by the Preferred
Securities Guarantee Trustee for the benefit of the Holders, and the Preferred

Guarantee to any Person except a Holder exercising his or her rights pursuant to

acceptance by such Successor Preferred Securities Guarantee Trustee of its
appointment to act as Successor Preferred Securities Guarantee Trustee. The
right, title and interest of the Preferred Securities Guarantee Trustee shall
automatically vest in any Successor Preferred Securities Guarantee Trustee, and
such vesting and succession of title shall be effective whether or not
conveyancing documents have been executed and delivered pursuant to the
appointment of such Successor Preferred Securities Guarantee Trustee.

         (b) If an Event of Default actually known to a Responsible Officer has
occurred and is continuing, the Preferred Securities Guarantee Trustee shall
enforce this Preferred Securities Guarantee for the benefit of the Holders.

         (c) The Preferred Securities Guarantee Trustee, before the occurrence
of any Event of Default and after the curing of all Events of Default that may
have occurred, shall undertake to perform only such duties as are specifically
set forth in this Preferred Securities Guarantee, and no implied covenants shall
be read into this Preferred Securities Guarantee against the Preferred
Securities Guarantee Trustee. In case an Event of Default has occurred (that has
not been cured or waived pursuant to SECTION 2.6) and is actually known to a
Responsible Officer, the Preferred Securities Guarantee Trustee shall exercise
such of the rights and powers vested in it by this Preferred Securities
Guarantee, and use the same degree of care and skill in its exercise thereof,

                                       7
<Page>

as a prudent person would exercise or use under the circumstances in the
conduct of his or her own affairs.

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

                  (i)      prior to the occurrence of any Event of Default and
         after the curing or waiving of all such Events of Default that may have
         occurred:

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

                           (B)      in the absence of bad faith on the part of
the Preferred Securities Guarantee Trustee, the Preferred Securities Guarantee
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 Preferred Securities Guarantee Trustee and conforming to the
requirements of this Preferred Securities Guarantee; but in the case of any such
certificates or opinions that by any provision hereof are specifically required
to be furnished to the Preferred Securities Guarantee Trustee, the Preferred
Securities Guarantee Trustee shall be under a duty to examine the same to
determine whether or not they conform to the requirements of this Preferred
Securities Guarantee;

                  (ii)     the Preferred Securities Guarantee Trustee shall not
         be liable for any error of judgment made in good faith by a Responsible
         Officer, unless it shall be proved that the Preferred Securities
         Guarantee Trustee was negligent in ascertaining the pertinent facts
         upon which such judgment was made;

                  (iii)    the Preferred Securities Guarantee Trustee shall not
         be liable with respect to any action taken or omitted to be taken by it
         in good faith in accordance with the direction of the Holders of a
         Majority in liquidation amount of the Preferred Securities relating to
         the time, method and place of conducting any proceeding for any remedy
         available to the Preferred Securities Guarantee Trustee, or the
         exercise of any trust or power conferred upon the Preferred Securities
         Guarantee Trustee under this Preferred Securities Guarantee; and

                  (iv)     no provision of this Preferred Securities Guarantee
         shall require the Preferred Securities Guarantee Trustee to expend or
         risk its own funds or otherwise incur personal financial liability in
         the performance of any of its duties or in the exercise of any of its
         rights or powers, if the Preferred Securities Guarantee Trustee shall
         have reasonable grounds for believing that the repayment of such funds

         Securities Guarantee, the Preferred Securities Guarantee Trustee shall
         deem it desirable that a matter be proved or established before taking,
         suffering or omitting any action hereunder, the Preferred Securities
         Guarantee Trustee (unless other evidence is herein specifically

         advice or opinion. Such counsel may be counsel to the Guarantor or any
         of its Affiliates and may include any of its employees. The Preferred
         Securities Guarantee Trustee shall have the right at any time to seek

         under no obligation to exercise any of the rights or powers vested in
         it by this Preferred Securities Guarantee at the request or direction

         Securities Guarantee Trustee such security and indemnity, reasonably
         satisfactory to the Preferred Securities Guarantee Trustee, against the
         costs, expenses (including attorneys' fees and expenses and the

         Preferred Securities Guarantee.

                  (vii)    The Preferred Securities Guarantee 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, direction, consent, order, bond, debenture, note,
         other evidence of indebtedness or other paper or document, but the
         Preferred Securities Guarantee Trustee, in its discretion, may make
         such further inquiry or investigation into such facts or matters as it
         may see fit. (viii) The Preferred Securities Guarantee Trustee may
         execute any of the trusts or powers hereunder or perform any duties
         hereunder either directly or by or through agents, nominees, custodians
         or attorneys, and the Preferred Securities Guarantee Trustee shall not
         be responsible for any misconduct or negligence on the part of any
         agent or attorney appointed with due care by it hereunder.

                  (ix)     Any action taken by the Preferred Securities
         Guarantee Trustee or its agents hereunder shall bind the Holders, and
         the signature of the Preferred Securities Guarantee Trustee or its
         agents alone shall be sufficient and effective to perform any such
         action. No third party shall be required to inquire as to the authority
         of the Preferred Securities Guarantee Trustee to so act or as to its
         compliance with any of the terms and provisions of this Preferred
         Securities Guarantee, both of which shall be conclusively evidenced by
         the Preferred Securities Guarantee Trustee's or its agent's taking such
         action.

         Securities Guarantee the Preferred Securities Guarantee Trustee shall
         deem it desirable to receive instructions with respect to enforcing any
         remedy or right or taking any other action hereunder, the Preferred
         Securities Guarantee Trustee (i) may request instructions from the
         Holders of a Majority in liquidation amount of the Preferred
         Securities, (ii) may refrain from enforcing such remedy or right or
         taking such other action until such instructions are received, and
         (iii) shall be protected in conclusively relying on or acting in
         accordance with such instructions.

                  (xi)     The Preferred Securities Guarantee Trustee shall not
         be liable for any action taken, suffered, or omitted to be taken by it
         in good faith, without negligence, and reasonably believed by it to be
         authorized or within the discretion or rights or powers conferred upon
         it by this Preferred Securities Guarantee.

         (b) No provision of this Preferred Securities Guarantee shall be deemed
to impose any duty or obligation on the Preferred Securities Guarantee Trustee
to perform any act or acts or exercise any right, power, duty or obligation
conferred or imposed on it in any jurisdiction in which it shall be illegal, or
in which the Preferred Securities Guarantee Trustee shall be unqualified or
incompetent in accordance with applicable law, to perform any such act or acts
or to exercise any such right, power, duty or obligation. No permissive power or
authority available to the Preferred Securities Guarantee Trustee shall be
construed to be a duty.

         examining authority referred to above, then, for the purposes of this
         SECTION 4.1(a)(ii), the combined capital and surplus of such
         corporation shall be deemed to be its combined capital and surplus as
         set forth in its most recent report of condition so published.

         (b) If at any time the Preferred Securities Guarantee Trustee shall
cease to be eligible to so act under SECTION 4.1(a), the Preferred Securities
Guarantee Trustee shall immediately resign in the manner and with the effect set
out in SECTION 4.2(c).

         (c) If the Preferred Securities Guarantee Trustee has or shall acquire
any "CONFLICTING INTEREST" within the meaning of Section 310(b) of the Trust

Trustee may be appointed or removed without cause at any time by the Guarantor
except during an Event of Default.

         (b) The Preferred Securities Guarantee Trustee shall not be removed in

resign from office (without need for prior or subsequent accounting) by an

delivered to the Guarantor, which resignation shall not take effect until a
Successor Preferred Securities Guarantee Trustee has been appointed and has
accepted such appointment by instrument in writing executed by such Successor

resigning Preferred Securities Guarantee Trustee.

         (d) If no Successor Preferred Securities Guarantee Trustee shall have

60 days after delivery of an instrument of removal or resignation, the
Preferred Securities Guarantee Trustee resigning or being removed may, at the
expense of the Guarantor, petition any court of competent jurisdiction for
appointment of a Successor Preferred Securities Guarantee Trustee. Such court
may thereupon, after prescribing such notice, if any, as it may deem proper,
appoint a Successor Preferred Securities Guarantee Trustee.

         (e) No Preferred Securities Guarantee Trustee shall be liable for the
acts or omissions to act of any Successor Preferred Securities Guarantee
Trustee.

         (f) Upon termination of this Preferred Securities Guarantee or removal

SECTION 4.2, the Guarantor shall pay to the Preferred Securities Guarantee
Trustee all amounts due to the Preferred Securities Guarantee Trustee accrued to
the date of such termination, removal or resignation.

                                    ARTICLE V
                                    GUARANTEE

SECTION 5.1 GUARANTEE.

         The Guarantor irrevocably and unconditionally agrees to pay in full to
the Holders the Guarantee Payments (without duplication of amounts theretofore
paid by the Issuer), as and when due, regardless of any defense, right of set
off or counterclaim that the Issuer may have or assert. The Guarantor's
obligation to make a Guarantee Payment may be satisfied by direct payment of the
required amounts by the Guarantor to the Holders or by causing the Issuer to pay
such amounts to the Holders.

SECTION 5.2 WAIVER OF NOTICE AND DEMAND.

         The Guarantor hereby waives notice of acceptance of this Preferred
Securities Guarantee and of any liability to which it applies or may apply,
presentment, demand for payment, any right to require a proceeding first against
the Issuer or any other Person before proceeding against the Guarantor, protest,
notice of nonpayment, notice of dishonor, notice of redemption and all other
notices and demands. Notwithstanding anything to the contrary herein, the
Guarantor retains all of its rights under the Indenture to extend the interest
payment period on the Debentures and the Guarantor shall not be obligated
hereunder to make any Guarantee Payment during any extended Interest Payment
Period (as defined in the Indenture) with respect to the Distributions (as
defined in the Declaration) on the Preferred Securities.

                                       12
<Page>

SECTION 5.3 OBLIGATIONS NOT AFFECTED.

         The obligations, covenants, agreements and duties of the Guarantor
under this Preferred Securities Guarantee shall be absolute and unconditional
and shall remain in full force and effect until the entire liquidation amount of
all outstanding Preferred Securities shall have been paid and such obligation
shall in no way be affected or impaired by reason of the happening from time to
time of any of the following:

         (a) the release or waiver, by operation of law or otherwise, of the
performance or observance by the Issuer of any express or implied agreement,
covenant, term or condition relating to the Preferred Securities to be performed
or observed by the Issuer;

         (b) the extension of time for the payment by the Issuer of all or any
portion of the Distributions, Redemption Price, Liquidation Distribution or any
other sums payable under the terms of the Preferred Securities or the extension
of time for the performance of any other obligation under, arising out of, or in
connection with, the Preferred Securities (other than an extension of time for
payment of Distributions, Redemption Price, Liquidation Distribution or other
sum payable that results from the extension of any interest payment period on
the Debentures permitted by the Indenture);

         (c) any failure, omission, delay or lack of diligence on the part of
the Property Trustee or the Holders to enforce, assert or exercise any right,
privilege, power or remedy conferred on the Property Trustee or the Holders
pursuant to the terms of the Preferred Securities, or any action on the part of
the Issuer granting indulgence or extension of any kind;

         (d) the voluntary or involuntary liquidation, dissolution, sale of any
collateral, receivership, insolvency, bankruptcy, assignment for the benefit of
creditors, reorganization, arrangement, composition or readjustment of debt of,
or other similar proceedings affecting, the Issuer or any of the assets of the
Issuer;

         (e) any invalidity of, or defect or deficiency in, the Preferred
Securities;

         (f) the settlement or compromise of any obligation guaranteed hereby or
hereby incurred; or

         (g) any other circumstance whatsoever that might otherwise constitute a
legal or equitable discharge or defense of a guarantor, it being the intent of
this SECTION 5.3 that the obligations of the Guarantor with respect to the
Guarantee Payments shall be absolute and unconditional under any and all
circumstances.

         There shall be no obligation of the Holders to give notice to, or
obtain consent of, the Guarantor with respect to the happening of any of the
foregoing.

SECTION 5.4 RIGHTS OF HOLDERS.

         (a) The Holders of a Majority in liquidation amount of the Preferred
Securities have the right to direct the time, method and place of conducting any
proceeding for any remedy available to the Preferred Securities Guarantee
Trustee in respect of this Preferred Securities Guarantee or

                                       13
<Page>

to direct the exercise of any trust or power conferred upon the Preferred
Securities Guarantee Trustee under this Preferred Securities Guarantee.

         (b) If the Preferred Securities Guarantee Trustee fails to enforce such
Preferred Securities Guarantee, any Holder may institute a legal proceeding
directly against the Guarantor to enforce its rights under this Preferred
Securities Guarantee, without first instituting a legal proceeding against the
Issuer, the Preferred Securities Guarantee Trustee or any other person or
entity. Notwithstanding the foregoing, if the Guarantor has failed to make a
Guarantee Payment, a Holder may directly institute a proceeding in such Holder's
own name against the Guarantor for enforcement of the Preferred Securities
Guarantee for such payment. The Guarantor waives any right or remedy to require
that any action be brought first against the Issuer or any other person or
entity before proceeding directly against the Guarantor.

SECTION 5.5 GUARANTEE OF PAYMENT.

         This Preferred Securities Guarantee creates a guarantee of payment and
not of collection.

SECTION 5.6 SUBROGATION.

         The Guarantor shall be subrogated to all (if any) rights of the Holders
against the Issuer in respect of any amounts paid to such Holders by the
Guarantor under this Preferred Securities Guarantee; provided, however, that the
Guarantor shall not (except to the extent required by mandatory provisions of
law) be entitled to enforce or exercise any right that it may acquire by way of
subrogation or any indemnity, reimbursement or other agreement, in all cases as
a result of payment under this Preferred Securities Guarantee, if, at the time
of any such payment, any amounts are due and unpaid under this Preferred
Securities Guarantee. If any amount shall be paid to the Guarantor in violation
of the preceding sentence, the Guarantor agrees to hold such amount in trust for
the Holders and to pay over such amount to the Holders.

SECTION 5.7 INDEPENDENT OBLIGATIONS.

         The Guarantor acknowledges that its obligations hereunder are
independent of the obligations of the Issuer with respect to the Preferred
Securities, and that the Guarantor shall be liable as principal and as debtor
hereunder to make Guarantee Payments pursuant to the terms of this Preferred
Securities Guarantee notwithstanding the occurrence of any event referred to in
subsections (a) through (h), inclusive, of SECTION 5.3 hereof.

                    LIMITATION OF TRANSACTIONS; SUBORDINATION

SECTION 6.1 LIMITATION OF TRANSACTIONS.

         So long as any Preferred Securities remain outstanding, the Guarantor
shall not, and shall not permit any subsidiary of the Guarantor to, (i) declare
or pay any dividends or distributions on, or redeem, purchase, acquire, or make
a liquidation payment with respect to, any of the Guarantor's capital stock
(which includes common and preferred stock) (other than (a) dividends or
distributions in shares of, or options, warrants, rights to subscribe for or
purchase shares of, common stock of the Guarantor, (b) any declaration of a
dividend in connection with the

                                       14
<Page>

implementation of a stockholders' rights plan, or the issuance of stock under
any such plan in the future, or the redemption or repurchase of any such
rights pursuant thereto, (c) as a result of a reclassification of the
Guarantor's capital stock or the exchange or the conversion of one class or
series of the Guarantor's capital stock for another class or series of the
Guarantor's capital stock, (d) the purchase of fractional interests in shares
of the Guarantor's capital stock pursuant to the conversion or exchange
provisions of such capital stock or the security being converted or
exchanged, and (e) purchases of the Guarantor's common stock related to the
issuance of the Guarantor's common stock or rights under any of the
Guarantor's benefit plans for its directors, officers, employees or any of
the Guarantor's dividend reinvestment plans), (ii) make any payment of
principal of, or premium, if any, or interest on or repay, repurchase or
redeem any debt securities of the Guarantor (including any Other Debentures)
that rank PARI PASSU with or junior in right of payment to the Debentures or
(iii) make any guarantee payments with respect to any guarantee (other than
payments under the Preferred Securities Guarantee) by the Guarantor of the
debt securities of any subsidiary of the Guarantor (including Other
Guarantees) if such guarantee ranks PARI PASSU with or junior in right of
payment to the Debentures, if at such time (1) there shall have occurred any
event of which the Guarantor has actual knowledge that (a) with the giving of
notice or the lapse of time, or both, would constitute an Indenture Event of
Default and (b) in respect of which the Guarantor shall not have taken
reasonable steps to cure, (2) an Indenture Event of Default shall have
occurred and be continuing, (3) if such Debentures are held by the Property
Trustee, the Guarantor shall be in default with respect to its payment of any
obligations under this Preferred Securities Guarantee or (4) the Guarantor
shall have given notice of its election of the exercise of its right to
extend the interest payment period pursuant to Section 16.01 of the Indenture
or such extension period, or any such extension shall have commenced and be
continuing.

         Notwithstanding the foregoing, if an Event of Default has occurred and
is continuing under the Declaration, the rights of the holders of the Common
Securities to receive Guarantee Payments under the Common Securities Guarantee
or any Other Common Securities Guarantee shall be subordinated to the rights of
the holders of the Preferred Securities, to receive payments of all amounts due
and owing to such holders under this Preferred Securities Guarantee or any Other
Guarantee.

SECTION 6.2 RANKING.

         This Preferred Securities Guarantee will constitute an unsecured
obligation of the Guarantor and will rank (i) subordinate and junior in right of
payment to Senior Indebtedness (as defined in the Indenture), to the same extent
and in the same manner that the Debentures are subordinated to Senior
Indebtedness pursuant to the Indenture, (ii) PARI PASSU with the Debentures, the
Other Debentures, the Common Securities Guarantee and any Other Guarantee and
any Other Common Securities Guarantee, and (iii) senior to the Guarantor's
capital stock.

defined in the Declaration) of all Preferred Securities, or (ii) upon
liquidation of the Issuer, the full payment of the amounts payable in accordance
with the Declaration or the distribution of the Debentures to the Holders and

reinstated, as the case may be, if at any time any Holder must restore payment
of any sums paid under the Preferred Securities or under this Preferred
Securities Guarantee.

in damages or otherwise to the Guarantor or any Covered Person for any loss,
damage or claim incurred by reason of any act or omission performed or omitted
by such Indemnified Person in good faith in accordance with this Preferred
Securities Guarantee and in a manner that such Indemnified Person reasonably
believed to be within the scope of the authority conferred on such Indemnified
Person by this Preferred Securities Guarantee or by law, except that an
Indemnified Person shall be liable for any such loss, damage or claim incurred
by reason of such Indemnified Person's negligence or willful misconduct with
respect to such acts or omissions.

         (b) An Indemnified Person shall be fully protected in relying in good
faith upon the records of the Guarantor and upon such information, opinions,

hold each Indemnified Person harmless against, any and all loss, liability,
damage, claim or expense incurred without negligence or bad faith on its part,
arising out of or in connection with the acceptance or administration of the
trust or trusts hereunder, including the costs and expenses (including
reasonable legal fees and expenses) of defending itself against, or
investigating, any claim (whether asserted by the Guarantor, a Holder or any
