Section 2.04. EXECUTION AND AUTHENTICATION.

An Officer shall sign the Securities for the Company by manual or facsimile
signature.

If an Officer whose signature is on a Security no longer holds that office at
the time a Security is authenticated, the Security shall nevertheless be valid.

A Security shall not be valid until authenticated by the manual signature of the
Trustee. The signature shall be conclusive evidence that the Security has been
authenticated under this Indenture.

The Trustee shall, upon a written order of the Company signed by an Officer (an
"AUTHENTICATION ORDER"), together with an Officers' Certificate and an Opinion
of Counsel, authenticate Securities for original issue in the aggregate
principal amount stated in the Authentication Order.

The Trustee may appoint an authenticating agent acceptable to the Company to
authenticate Securities. An authenticating agent may authenticate Securities
whenever the Trustee may do so. Each reference in this Indenture to
authentication by the Trustee includes authentication by such agent. An
authenticating agent has the same rights as an Agent to deal with Holders or an
Affiliate of the Company.

Notwithstanding the foregoing, if any Security shall have been authenticated and
delivered hereunder but never issued and sold by the Company, and the Company
shall deliver such Security to the Trustee for cancellation as provided in
Section 2.13 together with a written statement stating that such Security has
never been issued and sold by the Company, for all purposes of this Indenture
such Security shall be deemed never to have been authenticated and delivered
hereunder and shall not be entitled to the benefits of this Indenture.

Section 2.05. REGISTRAR AND PAYING AGENT; APPOINTMENT OF DEPOSITARY.

The Company shall maintain an office or agency where Securities may be presented
for registration of transfer or for exchange ("REGISTRAR") and an office or
agency where Securities may be presented for payment ("PAYING AGENT"). The
Registrar shall keep a register of the Securities and of their transfer and
exchange. The Company may appoint one or more co-registrars and one or more
additional paying agents. The term "REGISTRAR" includes any co-registrar and the
term "PAYING AGENT" includes any additional paying agent. The Company may change
any Paying Agent or Registrar without notice to any Holder. The Company shall
promptly notify the Trustee in writing of the name and address of any Agent not
a party to this Indenture. If the Company fails to appoint or maintain another
entity as Registrar or Paying Agent, the Trustee shall act as such. The Company
or any of its Subsidiaries may act as Paying Agent or Registrar.

The Company initially appoints The Depository Trust Company to act as Depositary
with respect to the Global Securities.

The Company initially appoints the Trustee to act as the Registrar and Paying
Agent with respect to the Securities and to act as Custodian with respect to the
Global Securities.

Section 2.06. PAYING AGENT TO HOLD MONEY IN TRUST.

The Company shall require each Paying Agent other than the Trustee to agree in
writing that the Paying Agent will hold in trust for the benefit of Holders or
the Trustee all money held by the Paying Agent for the payment of principal,
premium or interest on the Securities or other payments in respect of the
Securities or otherwise held by it as Paying Agent, and will notify the Trustee
of any default by the Company in making any such payment when due. While any
such default continues, the Trustee may require a Paying Agent to pay all money
held by it to the Trustee. The Company at any time may require a Paying Agent to
pay all money held by it to the Trustee. Upon payment over to the Trustee, the
Paying Agent (if other than the Company or a Subsidiary) shall have no further
liability for the money. If the Company or a Subsidiary acts as Paying Agent, it
shall segregate and hold in a separate trust fund for the benefit of the Holders
all money held by it as Paying Agent. Upon any bankruptcy or reorganization
proceedings relating to the Company, the Trustee shall serve as Paying Agent for
the Securities.

Section 2.07. HOLDER LISTS.

The Trustee shall preserve in as current a form as is reasonably practicable the
most recent list available to it of the names and addresses of all Holders and
shall otherwise comply with TIA ss.312(a). If the Trustee is not the Registrar,
the Company shall furnish to the Trustee at least seven Business Days before
each Interest Payment Date and at such other times as the Trustee may request in
writing, a list in such form and as of such date as the Trustee may reasonably
require of the names and addresses of the Holders of Securities, and the Company
shall otherwise comply with TIA ss.312(a).

Section 2.08. TRANSFER AND EXCHANGE.

(a)  Upon surrender for registration of transfer of any certificated Security of
     any series at the office or agency maintained pursuant to Section 4.02 in a
     place of payment for that series, the Company shall execute, and the
     Trustee shall authenticate and deliver, in the name of the designated
     transferee or transferees, one or more new certificated Securities of the
     same series, of any authorized denominations and of a same aggregate
     principal amount and like tenor and containing identical terms and
     provisions.

(b)  At the option of the Holder, Securities of any series (except a Security in
     global form) may be exchanged for other Securities of the same series, of
     any authorized denominations, of a same aggregate principal amount and like
     tenor and containing identical terms and provisions, upon surrender of the
     Securities to be exchanged at such office or agency. Whenever any
     Securities are so surrendered for exchange, the Company shall execute, and
     the Trustee shall authenticate and deliver, the Securities which the Holder
     making the exchange is entitled to receive.

(c)  Notwithstanding any other provision of this Section, unless and until it is
     exchanged in whole or in part for Securities in certificated form, a
     Security in global form representing all or a portion of the Securities of
     a series may not be transferred except as a whole by the Depositary for
     such series to a nominee of such Depositary or by a nominee of such
     Depositary to such Depositary or another nominee of such Depositary or by
     such

                                       12
<Page>

     Depositary or any such nominee to a successor Depositary for such series or
     a nominee of such successor Depositary.

(d)  If at any time the Depositary for the Securities of a series notifies the
     Company that it is unwilling or unable to continue as Depositary for the
     Securities of such series or if at any time the Depositary for the
     Securities of such series shall no longer be registered and in good
     standing as a clearing agency under the Exchange Act, the Company shall
     appoint a successor Depositary with respect to the Securities of such
     series. If a successor Depositary for the Securities of such series is not
     appointed by the Company prior to the resignation of the Depositary and, in
     any event, within 90 days after the Company receives such notice or becomes
     aware of such ineligibility, the Company's designation of the Depositary
     pursuant to Section 2.02(b)(21) shall no longer be effective with respect
     to the Securities of such series and the Company shall execute, and the
     Trustee, upon receipt of an Authentication Order for the authentication and
     delivery of certificated Securities of such series of like tenor, shall
     authenticate and deliver, Securities of such series of like tenor in
     certificated form, in authorized denominations and in an aggregate
     principal amount equal to the principal amount of the Security or
     Securities of such series of like tenor in global form in exchange for such
     Security or Securities in global form.

(e)  The Company may at any time in its sole discretion determine that all (but
     not less than all) Securities of a series issued in global form shall no
     longer be represented by such a Security or Securities in global form. In
     such event the Company shall execute, and the Trustee, upon receipt of an
     Authentication Order for the authentication and delivery of certificated
     Securities of such series of like tenor, shall authenticate and deliver,
     Securities of such series of like tenor in certificated form, in authorized
     denominations and in an aggregate principal amount equal to the principal
     amount of the Security or Securities of such series of like tenor in global
     form in exchange for such Security or Securities in global form.

(f)  If specified by the Company pursuant to Section 2.02 with respect to a
     series of Securities, the Depositary for such series may surrender a
     Security in global form of such series in exchange in whole or in part for
     Securities of such series in certificated form on such terms as are
     acceptable to the Company and such Depositary. Thereupon, the Company shall
     execute, and the Trustee shall authenticate and deliver, without service
     charge, (i) to each Person specified by such depositary a new certificated
     Security or Securities of the same series of like tenor, of any authorized
     denomination as requested by such Person in aggregate principal amount
     equal to and in exchange for such Person's beneficial interest in the
     Security in global form; and (ii) to such Depositary a new Security in
     global form of like tenor in a denomination equal to the difference, if
     any, between the principal amount of the surrendered Security in global
     form and the aggregate principal amount of certificated Securities
     delivered to Holders thereof.

(g)  Upon the exchange of a Security in global form for Securities in
     certificated form, such Security in global form shall be canceled by the
     Trustee. Securities in certificated form issued in exchange for a Security
     in global form pursuant to this Section shall be registered in such names
     and in such authorized denominations as the Depositary for such Security in
     global form, pursuant to instructions from its direct or Indirect
     Participants or

                                       13
<Page>

     otherwise, shall instruct the Trustee in writing. The Trustee shall deliver
     such Securities to the Persons in whose names such Securities are so
     registered.

(h)  Whenever any Securities are surrendered for exchange, the Company shall
     execute, and the Trustee shall authenticate and deliver, the Securities
     which the Holder making the exchange is entitled to receive.

(i)  All Securities issued upon any registration of transfer or upon any
     exchange of Securities shall be the valid obligations of the Company,
     evidencing the same debt, and entitled to the same benefits under this
     Indenture, as the Securities surrendered upon such registration of transfer
     or exchange.

(j)  Every Security presented or surrendered for registration of transfer or for
     exchange shall (if so required by the Company, the Registrar or the
     Trustee) be duly endorsed, or be accompanied by a written instrument of
     transfer in form satisfactory to the Company, the Registrar and the Trustee
     duly executed by the Holder thereof or his attorney duly authorized in
     writing.

(k)  No service charge shall be made for any registration of transfer or for any
     exchange of Securities, but the Company may require payment of a sum
     sufficient to cover any tax or other governmental charge that may be
     imposed in connection with any registration or transfer or exchange of
     Securities, other than exchanges pursuant to Section 2.12 or 3.06 not
     involving any transfer.

(l)  The Company shall not be required (i) to issue, register the transfer of,
     or exchange any Securities for a period beginning at the opening of
     business 15 days before any selection for redemption of Securities of like
     tenor and of the series of which such Security is a part and ending at the
     close of business on the earliest date on which the relevant notice of
     redemption is deemed to have been given to all Holders of Securities of
     like tenor and of such series to be redeemed; or (ii) to 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.

(m)  The foregoing provisions relating to registration, transfer and exchange
     may be modified, supplemented or superseded with respect to any series of
     Securities by a Board Resolution or in one or more indentures supplemental
     hereto.

                                       14
<Page>

(n)  The following legend shall appear on the face of all Global Securities
     unless specifically stated otherwise in the applicable provision of this
     Indenture:

     "THIS GLOBAL SECURITY IS HELD BY THE DEPOSITARY (AS DEFINED IN THE
     INDENTURE GOVERNING THIS SECURITY) OR ITS NOMINEE IN CUSTODY FOR THE
     BENEFIT OF THE BENEFICIAL OWNERS HEREOF, AND, UNLESS AND UNTIL IT IS
     EXCHANGED FOR SECURITIES IN DEFINITIVE FORM IN ACCORDANCE WITH THE
     INDENTURE, (I) IS NOT TRANSFERABLE EXCEPT AS A WHOLE BY THE DEPOSITARY
     TO A NOMINEE OF THE DEPOSITARY, OR BY A NOMINEE OF THE DEPOSITARY TO
     THE DEPOSITARY OR ANOTHER NOMINEE OF THE DEPOSITARY, OR BY THE
     DEPOSITARY OR ANY SUCH NOMINEE TO A SUCCESSOR DEPOSITARY OR SUCCESSOR
     NOMINEE, AND (II) MAY NOT BE EXCHANGED OR CANCELLED EXCEPT IN THE
     LIMITED CIRCUMSTANCES DESCRIBED IN THE INDENTURE."

(o)  At such time as all beneficial interests in a particular Global Security
     have been exchanged for definitive Securities or a particular Global
     Security has been redeemed, repurchased or canceled in whole and not in
     part, each such Global Security shall be returned to or retained and
     canceled by the Trustee in accordance with Section 2.13 hereof. At any time
     prior to such cancellation, if any beneficial interest in a Global Security
     is exchanged for or transferred to a Person who will take delivery thereof
     in the form of a beneficial interest in another Global Security or for
     definitive Securities, the principal amount of Securities represented by
     such Global Security shall be reduced accordingly and an endorsement shall
     be made on such Global Security by the Trustee or by the Depositary at the
     direction of the Trustee to reflect such reduction; and if the beneficial
     interest is being exchanged for or transferred to a Person who will take
     delivery thereof in the form of a beneficial interest in another Global
     Security, such other Global Security shall be increased accordingly and an
     endorsement shall be made on such Global Security by the Trustee or by the
     Depositary at the direction of the Trustee to reflect such increase.

(p)  Prior to due presentment for the registration of a transfer of any
     Security, the Trustee, any Agent and 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
     interest on such Securities and for all other purposes, and neither the
     Trustee, any Agent nor the Company shall be affected by notice to the
     contrary. Notwithstanding the foregoing, with respect to any Global
     Security, nothing herein shall prevent the Company, the Trustee or any
     agent of the Company or the Trustee from giving effect to any written
     certification, proxy or other authorization furnished by any Depositary, as
     a Holder, with respect to such Global Security or impair, as between such
     Depositary and owners of beneficial interests in such Global Security, the
     operation of customary practices governing the exercise of the rights of
     such Depositary (or its nominee) as Holder of such Global Security.

Section 2.09. REPLACEMENT SECURITIES.

If any mutilated Security is surrendered to the Trustee or the Company and the
Trustee receives evidence to its satisfaction of the destruction, loss or theft
of any Security, the Company shall issue and the Trustee, upon receipt of an
Authentication Order, shall authenticate a replacement Security if the Trustee's
requirements are met. If required by the Trustee or the Company, 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 and any
authenticating agent from any loss that any of them may suffer if a Security is
replaced. The Company may charge for its expenses in replacing a Security.

Every replacement Security is an additional 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 2.10. OUTSTANDING SECURITIES.

The Securities outstanding at any time are all the Securities authenticated by
the Trustee except for those canceled by it, those delivered to it for
cancellation, those reductions in the interest in a Global Security effected by
the Trustee in accordance with the provisions hereof, and those described in
this Section as not outstanding. Except as set forth in Section 2.11 hereof, a
Security does not cease to be outstanding because the Company or an Affiliate of
the Company holds the Security.

If a Security is replaced pursuant to Section 2.09 hereof, it ceases to be
outstanding unless the Trustee receives proof satisfactory to it that the
replaced Security is held by a "protected purchaser" (within the meaning of
Article 8 of the Uniform Commercial Code) or a Person with comparable status
under other applicable law.

If the principal amount of any Security is considered paid under Section 4.01
hereof, it ceases to be outstanding and interest on it ceases to accrue.

If the Paying Agent (other than the Company, a Subsidiary or an Affiliate of any
thereof) holds, on a redemption date or maturity date, money sufficient to pay
Securities payable on that date, then on and after that date such Securities
shall be deemed to be no longer outstanding and shall cease to accrue interest.

Section 2.11. TREASURY SECURITIES.

In determining whether the Holders of the required principal amount of
Securities have concurred in any direction, waiver or consent, Securities owned
by the Company, or by any Person directly or indirectly controlling or
controlled by or under direct or indirect common control with the Company, shall
be considered as though not outstanding, except that for the purposes of
determining whether the Trustee shall be protected in relying on any such
direction, waiver or consent, only Securities that the Trustee knows are so
owned shall be so disregarded.

                                       16
<Page>

Section 2.12. TEMPORARY SECURITIES.

Until certificates representing Securities are ready for delivery, the Company
may prepare and the Trustee, upon receipt of an Authentication Order, shall
authenticate temporary Securities. Temporary Securities shall be substantially
in the form of certificated Securities but may have variations that the Company
considers appropriate for temporary Securities and as shall be reasonably
acceptable to the Trustee. Without unreasonable delay, the Company shall prepare
and the Trustee shall authenticate definitive Securities in exchange for
temporary Securities.

Holders of temporary Securities shall be entitled to all of the benefits of this
Indenture.

Section 2.13. CANCELLATION.

The Company at any time may deliver Securities to the Trustee for cancellation.
The Registrar and Paying Agent shall forward to the Trustee any Securities
surrendered to them for registration of transfer, exchange or payment. The
Trustee and no one else shall cancel all Securities surrendered for registration
of transfer, exchange, payment, replacement or cancellation and shall destroy
canceled Securities (subject to the record retention requirement of the Exchange
Act). Certification of the destruction of all canceled Securities shall be
delivered to the Company. The Company may not issue new Securities to replace
Securities that it has paid or that have been delivered to the Trustee for
cancellation.

Section 2.14. DEFAULTED INTEREST.

If the Company defaults in a payment of interest on the Securities, it shall pay
the defaulted interest in any lawful manner plus, to the extent lawful, interest
payable on the defaulted interest, to the Persons who are Holders on a
subsequent special record date, in each case at the rate provided in the
Securities. The Company shall notify the Trustee in writing of the amount of
defaulted interest proposed to be paid on each Security and the date of the
proposed payment. The Company shall fix or cause to be fixed each such special
record date and payment date, PROVIDED that no such special record date shall be
less than 10 days prior to the related payment date for such defaulted interest.
At least 15 days before the special record date, the Company (or, upon the
written request of the Company, the Trustee in the name and at the expense of
the Company) shall mail or cause to be mailed to Holders a notice that states
the special record date, the related payment date and the amount of such
interest to be paid. Subject to the foregoing provisions of this Section, each
Security delivered under this Indenture upon registration of transfer of or in
exchange for or in lieu of any other Security shall carry the rights to interest
accrued and unpaid, and to accrue, which were carried by such other Security.

                                   ARTICLE 3.
                            REDEMPTION AND PREPAYMENT

Section 3.01. APPLICABILITY OF ARTICLE.

The provisions of this Article shall be applicable to the Securities of any
series which are redeemable before their maturity or to any sinking fund for the
retirement of Securities of a series except as otherwise specified as
contemplated by Section 2.02 for Securities of such series.

                                       17

Section 3.02. SELECTION OF SECURITIES TO BE REDEEMED.

If less than all of the Securities of any series are to be redeemed at any time,
the Trustee shall select the Securities of such series to be redeemed among the
Holders of the Securities of such series in compliance with the requirements of
the principal national securities exchange, if any, on which the Securities of
such series are listed or, if the Securities of such series are not so listed,
to be redeemed among the Holders of Securities of such series on a PRO RATA
basis, by lot or by such method as the Trustee deems fair and appropriate;
PROVIDED that no Securities of $1,000 or less shall be redeemed in part. In the
event of partial redemption by lot, the particular Securities of such series to
be redeemed shall be selected, unless otherwise provided herein, not less than
30 nor more than 60 days prior to the redemption date by the Trustee from the
outstanding Securities of the series not previously called for redemption.

The Trustee shall promptly notify the Company in writing of the Securities
selected for redemption and, in the case of any Security selected for partial
redemption, the principal amount thereof to be redeemed. Securities and portions
of Securities selected shall be in amounts of $1,000 or whole multiples of
$1,000; except that if all of the Securities of a series of a Holder are to be
redeemed, the entire outstanding amount of Securities of such series held by
such Holder, even if not a multiple of $1,000, shall be redeemed. A new Security
of the same series in principal amount equal to the unredeemed portion thereof
will be issued in the name of the Holder thereof upon cancellation of the
original Security. Securities called for redemption shall become due on the
redemption date. On and after the redemption date, interest will cease to accrue
on the Securities or portions of them called for redemption. Except as provided
in this Section 3.02, provisions of this Indenture that apply to Securities
called for redemption shall also apply to portions of Securities called for
redemption.

Section 3.03. NOTICE OF REDEMPTION.

At least 30 days but not more than 60 days before a redemption date, the Company
shall mail or cause to be mailed, by first class mail, a notice of redemption to
each Holder whose Securities are to be redeemed at its registered address.

The notice shall identify the Securities to be redeemed, including the series
thereof, and shall state:

(a)  the redemption date;

(b)  the redemption price;

(c)  the name and address of the Paying Agent;

(d)  that Securities called for redemption must be surrendered to the Paying
     Agent to collect the redemption price;

(e)  that, unless the Company defaults in making such redemption payment,
     interest on Securities called for redemption will cease to accrue on and
     after the redemption date;

                                       18
<Page>

(f)  that any Security being redeemed in part, the portion of the principal
     amount of such Security to be redeemed and that, after the redemption date
     upon surrender of such Security, a new Security or Securities of the same
     series in principal amount equal to the unredeemed portion shall be issued
     upon cancellation of the original;

(g)  the paragraph of the Securities and/or Section of this Indenture pursuant
     to which the Securities called for redemption are being redeemed; and

(h)  that no representation is made as to the correctness or accuracy of the
     CUSIP number, if any, listed in such notice or printed on the Securities.

At the Company's request, the Trustee shall give the notice of redemption in the
Company's name and at the Company's expense; PROVIDED, HOWEVER, that the Company
shall have delivered to the Trustee, at least 30 days prior to the redemption
date, an Officers' Certificate requesting that the Trustee give such notice and
setting forth the information to be stated in such notice as provided in the
preceding paragraph.

Section 3.04. EFFECT OF NOTICE OF REDEMPTION.

Once notice of redemption is mailed in accordance with Section 3.03 hereof,
Securities called for redemption become irrevocably due and payable on the
redemption date at the redemption price. A notice of redemption may not be
conditional.

Section 3.05. DEPOSIT OF REDEMPTION OR PURCHASE PRICE.

One Business Day prior to 10:00 a.m., Eastern Time, on any redemption date, the
Company shall deposit with the Trustee or with the Paying Agent money in
immediately available funds sufficient to pay the redemption or purchase price
of and accrued interest, if any, on all Securities to be redeemed or purchased
on that date. The Trustee or the Paying Agent shall promptly return to the
Company any money deposited with the Trustee or the Paying Agent by the Company
in excess of the amounts necessary to pay the redemption or purchase price of,
and accrued interest on, all Securities to be redeemed or purchased.

Section 3.06. SECURITIES REDEEMED OR PURCHASED IN PART.

Upon surrender of a Security that is redeemed or purchased in part, the Company
shall issue and, upon the Company's written request, the Trustee shall
authenticate for the Holder at the expense of the Company a new Security of the
same series equal in principal amount to the unredeemed or unpurchased portion
of the Security surrendered.

Section 3.07. MANDATORY REDEMPTION; SINKING FUND.

The Company shall not be required to make mandatory redemption or sinking fund
payments with respect to the Securities, unless otherwise specified in the terms
of a particular series of Securities. If a mandatory or optional sinking fund is
specified in the terms of a particular series of Securities, the following
provisions will apply thereto (unless otherwise specified):

                                       19
<Page>

The minimum amount of any sinking fund payment provided for by the terms of
Securities of any series is herein referred to as a "mandatory sinking fund
payment", and any payment in excess of such minimum amount provided for by the
terms of Securities of any series is herein referred to as an "optional sinking
fund payment." The last date on which any such payment may be made is herein
referred to as a "sinking fund payment date."

In lieu of making all or any part of any mandatory sinking fund payment with
respect to any Securities of a series in cash, the Company may at its option (a)
deliver to the Trustee Securities of that series theretofore purchased by the
Company and (b) may apply as a credit Securities of that series which have been
redeemed either at the election of the Company pursuant to the terms of such
Securities or through the application of optional sinking fund payments pursuant
to the next succeeding paragraph, in each case in satisfaction of all or any
part of any mandatory sinking fund payment, provided that such Securities have
not been previously so credited. Each such Security so delivered or applied as a
credit shall be credited at the sinking fund redemption price for such
Securities and the amount of any mandatory sinking fund shall be reduced
accordingly. If the Company intends so to deliver or credit such Securities with
respect to any mandatory sinking fund payment it shall deliver to the Trustee at
least 45 days prior to the next succeeding sinking fund payment date for such
series (a) a certificate signed by any Officer specifying the portion of such
sinking fund payment, if any, to be satisfied by payment of cash and the portion
of such sinking fund payment, if any, which is to be satisfied by delivering and
crediting such Securities and (b) any Securities to be so delivered. All
Securities so delivered to the Trustee shall be cancelled by the Trustee and no
Securities shall be authenticated in lieu thereof. If the Company fails to
deliver such certificate and Securities at or before the time provided above,
the Company shall not be permitted to satisfy any portion of such mandatory
sinking fund payment by delivery or credit of Securities.

At its option the Company may pay into the sinking fund for the retirement of
Securities of any particular series, on or before each sinking fund payment date
for such series, any additional sum in cash as specified by the terms of such
series of Securities. If the Company intends to exercise its right to make any
such optional sinking fund payment, it shall deliver to the Trustee at least 45
days prior to the next succeeding sinking fund payment date for such series of
Securities a certificate signed by any Officer stating that the Company intends
to exercise such optional right and specifying the amount which the Company
intends to pay on such sinking fund payment date. If the Company fails to
deliver such certificate at or before the time provided above, the Company shall
not be permitted to make any optional sinking fund payment with respect to such
sinking fund payment date. To the extent that such right is not exercised in any
year it shall not be cumulative or carried forward to any subsequent year.

If the sinking fund payment or payments (mandatory or optional) made in cash
plus any unused balance of any preceding sinking fund payments made in cash
shall exceed $50,000 (or a lesser sum if the Company shall so request) with
respect to the Securities of any particular series, it shall be applied by the
Trustee or one or more Paying Agents on the next succeeding sinking fund payment
date to the redemption of Securities of such series at the sinking fund
redemption price together with accrued interest to the date fixed for
redemption. The Trustee shall select, in the manner provided in Section 3.02,
for redemption on such sinking fund payment date a sufficient principal amount
of Securities of such series to exhaust said cash, as nearly as may be, and the
Trustee shall, at the expense and in the name of the Company, thereupon cause
notice of

                                       20
<Page>

redemption of Securities of such series to be given in substantially the manner
and with the effect provided in Sections 3.02 and 3.03 for the redemption of
Securities of that series in part at the option of the Company, except that the
notice of redemption shall also state that the Securities of such series are
being redeemed for the sinking fund. Any sinking fund moneys not so applied or
allocated by the Trustee or any Paying Agent to the redemption of Securities of
that series shall be added to the next cash sinking fund payment received by the
Trustee or the Paying Agent and, together with such payment, shall be applied in
accordance with the provisions of this Section 3.07. Any and all sinking fund
moneys held by the Trustee or any Paying Agent on the maturity date of the
Securities of any particular series, and not held for the payment or redemption
of particular Securities of such series, shall be applied by the Trustee or such
Paying Agent, together with other moneys, if necessary, to be deposited
sufficient for the purpose, to the payment of the principal of the Securities of
that series at maturity. On or before each sinking fund payment date, the
Company shall pay to the Trustee or to one or more Paying Agents in cash a sum
equal to all interest accrued to the date fixed for redemption on Securities to
be redeemed on the next following sinking fund payment date pursuant to this
Section. Neither the Trustee nor any Paying Agent shall redeem any Securities of
a series with sinking fund moneys, and the Trustee shall not mail any notice of
redemption of Securities for such series by operation of the sinking fund,
during the continuance of a default in payment of interest on such Securities or
of any Event of Default (other than an Event of Default occurring as a
consequence of this paragraph), except that if the notice of redemption of any
Securities shall theretofore have been mailed in accordance with the provisions
hereof, the Trustee or any paying agent shall redeem such Securities if cash
sufficient for that purpose shall be deposited with the Trustee or such paying
agent for that purpose in accordance with the terms of this Article 3. Except as
aforesaid, any moneys in the sinking fund for such series at the time when any
such default or Event of Default shall occur and any moneys thereafter paid into
the sinking fund shall, during the continuance of such default or Event of
Default, be held as security for the payment of all such Securities; provided,
however, that in case such Event of Default or default shall have been cured or
waived as provided herein, such moneys shall thereafter be applied on the next
succeeding sinking fund payment date on which such moneys may be applied
pursuant to the provisions of this Section 3.07.

                                   ARTICLE 4.
                                    COVENANTS

Section 4.01. PAYMENT OF SECURITIES.

The Company shall pay or cause to be paid the principal of, premium, if any, and
interest on the Securities on the dates and in the manner provided in the
Securities. Principal, premium, if any, and interest shall be considered paid on
the date due if the Paying Agent, if other than the Company or a Subsidiary
thereof, holds as of 10:00 a.m., Eastern Time, on the due date money deposited
by the Company in immediately available funds and designated for and sufficient
to pay all principal, premium, if any, and interest then due.

Section 4.02. MAINTENANCE OF OFFICE OR AGENCY.

for exchange and where notices and demands to or upon the Company in respect of
the Securities and this Indenture may be served. The Company shall give prompt
written notice to the Trustee of the location, and any change in the location,
of such office or agency. If at any time the Company shall fail to maintain any
such required office or agency or shall fail to furnish the Trustee with the
address thereof, such presentations, surrenders, notices and demands may be made
or served at the Trustee's principal agency in the Borough of Manhattan, the
City of New York, which currently is located at ____________________.

The Company may also from time to time designate one or more other offices or
agencies where the Securities may be presented or surrendered for any or all
such purposes and may from time to time rescind such designations; PROVIDED,
HOWEVER, that no such designation or rescission shall in any manner relieve the
Company of its obligation to maintain an office or agency in the Borough of
Manhattan, the City of New York for such purposes. The Company shall give prompt
written notice to the Trustee of any such designation or rescission and of any
change in the location of any such other office or agency.

     Section 314(a)(4) of the Trust Indenture Act.

(d)  Delivery of such reports, information and documents to the Trustee is for
     informational purposes only and the Trustee's receipt of such shall not
     constitute constructive notice of any information contained therein or
     determinable from information contained therein, including the Company's
     compliance with any of its covenants hereunder (as to which the Trustee is
     entitled to rely exclusively on Officers' Certificates).

Section 4.04. COMPLIANCE CERTIFICATE.

     each fiscal year, an Officers' Certificate stating that a review of the

     stating, as to each such Officer signing such certificate, that to the best
     of his or her knowledge the Company has kept, observed, performed and
     fulfilled each and every covenant contained in this Indenture and is not in
     default in the performance or observance of any of the terms, provisions
     and conditions of this Indenture (or, if a Default, Event of Default or
     other instance of non-compliance with any of the terms of this Indenture
     shall have occurred, describing all such Defaults, Events of Default or
     instances of non-compliance of which he or she may have knowledge and what

     premium, if any, or interest on the Securities is prohibited or if such
     event has occurred, a description of the event and what action the Company
     is taking or proposes to take with respect thereto.

     deliver to the Trustee, forthwith upon any Officer of the Company becoming
     aware of any Default or Event of Default, an Officers' Certificate
     specifying such Default or Event of Default and what action the Company is

such Significant Subsidiary and (ii) the rights (charter and statutory),
licenses and franchises of the Company and any of its Significant Subsidiaries;
PROVIDED, HOWEVER, that the Company shall not be required to preserve any such
right, license or franchise, or the corporate, partnership or other existence of
any of its Significant Subsidiaries, if the Board of Directors shall determine
that the preservation thereof is no longer desirable in the conduct of the
business of the Company and its Significant Subsidiaries, taken as a whole, and
that the loss thereof is not adverse in any material respect to the Holders of
the Securities.

Section 4.06. STAY, EXTENSION AND USURY LAWS.

The Company covenants (to the extent that it may lawfully do so) that it shall
not at any time insist upon, plead, or in any manner whatsoever claim or take
the benefit or advantage of, any stay, extension or usury law wherever enacted,
now or at any time hereafter in force, that 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 shall not, by resort to any such law, hinder, delay
or impede the execution of

                                       23

execution of every such power as though no such law has been enacted.

Section 5.01. MERGER, CONSOLIDATION, OR SALE OF ASSETS.

The Company may consolidate or merge with or into, convert itself into, or sell,
assign, transfer, lease, convey or otherwise dispose of (including any such
disposition that might be deemed to occur as a result of the conversion of the
Company into another form of organization) all or substantially all of its
properties or assets in one or more related transactions, to another Person
(other than an individual, a government or an agency or political subdivision of
a government), but only if (a) either (i) the Company is the surviving entity or
(ii) the Person formed by or surviving any such consolidation, merger or
conversion (if other than the Company) or to which such sale, assignment,
transfer, lease, conveyance or other disposition shall have been made is a

a form reasonably satisfactory to the Trustee; and (c) immediately after such
transaction no Default or Event of Default exists. If the Company requests the

of the Company in accordance with Section 5.01 hereof, the successor Person
formed by such consolidation or into or with which the Company is merged or
converted or to which such sale, assignment, transfer, lease, conveyance or
other disposition is made shall succeed to, and be substituted for (so that from
and after the date of such consolidation, merger, conversion, sale, lease,
conveyance or other disposition, the provisions of this Indenture referring to
the "Company" shall refer instead to the successor Person and not to the
Company), and may exercise every right and power of, the Company under this
Indenture with the same effect as if such successor Person had been named as the
Company herein; PROVIDED, HOWEVER, that the predecessor Company shall not be
relieved from the obligation to pay the principal of and interest on the
Securities except in the case of a sale of all of the Company's assets that
meets the requirements of Section 5.01 hereof.

                              DEFAULTS AND REMEDIES

Section 6.01. EVENTS OF DEFAULT.

An "Event of Default," with respect to Securities of any series shall have
occurred if:

(a)  the Company defaults in the payment when due of interest on, with respect
     to, any Security of that series and such default continues for a period of
     30 days;

(b)  the Company defaults in the payment when due of principal of or premium, if
     any, on, or sinking fund payment with respect to, any Security of that
     series when the same becomes due and payable at maturity, upon redemption
     or otherwise;

(c)  the Company fails to comply with any of the provisions of section 5.01
     hereof;

(d)  the Company fails to observe or perform any other covenant, representation,
     warranty or other agreement in this Indenture, with respect to any Security
     of that series for 60 days after notice to comply;

(e)  the Company, pursuant to or within the meaning of any Bankruptcy Law:

     (i)    commences a voluntary case;

     (ii)   consents to the entry of an order for relief against it in an
            involuntary case;

     (iii)  consents to the appointment of a custodian of it or for all or
            substantially all of its property;

     (iv)   makes a general assignment for the benefit of its creditors; or

     (v)    generally is not paying its debts as they become due;

(f)  a court of competent jurisdiction enters an order or decree under any
     Bankruptcy Law that:

     (i)    is for relief against the Company in an involuntary case;

     (ii)   appoints a custodian of the Company for all or substantially all of
            the property of the Company; or

     (iii)  orders the liquidation of the Company;

and the order or decree remains unstayed and in effect for 60 consecutive days;
or

(g)  any other event provided with respect to Securities of that series in the
     terms thereof as contemplated by Section 2.02 hereof shall occur.

                                       25
<Page>

The term "CUSTODIAN" as used in this Article 6 means any receiver, trustee,
assignee, liquidator or similar official under any Bankruptcy Law.

A Default under clause (d) with respect to the Securities of any series is not
an Event of Default until the Trustee notifies the Company, or the Holders of at
least 25% in principal amount of the then outstanding Securities of all series
affected by the Default (treating all such series as a single class) notify the
Company and the Trustee, of the Default and the Company does not cure the
Default within 60 days after receipt of the notice. The notice must specify the
Default, demand that it be remedied and state that the notice is a "NOTICE OF
DEFAULT."

Section 6.02. ACCELERATION.

If any Event of Default with respect to one or more series of Securities (other
than an Event of Default specified in clause (e) or (f) of Section 6.01 hereof)
occurs and is continuing, the Trustee or the Holders of at least 25% in
principal amount of the then outstanding Securities of all series with respect
to which an Event of Default shall have occurred and be continuing (treating all
such series as a single class) may declare all the Securities of all such series
to be due and payable immediately. Upon any such declaration, the principal of,
premium, if any, and accrued and unpaid interest with respect to the Securities
of all such series shall become due and payable immediately. Notwithstanding the
foregoing, if an Event of Default specified in clause (e) or (f) of Section 6.01
hereof occurs with respect to the Company, all outstanding Securities of all
series shall be due and payable immediately without further action or notice.

Section 6.03. OTHER REMEDIES.

If an Event of Default occurs and is continuing, the Trustee may pursue any
available remedy to collect the payment of principal, premium, if any, and
interest on the Securities or to enforce the performance of any provision of the
Securities or this Indenture.

The Trustee may maintain a proceeding even if it does not possess any of the
Securities or does not produce any of them in the proceeding. A delay or
omission by the Trustee or any Holder of a Security in exercising any right or
remedy accruing upon an Event of Default shall not impair the right or remedy or
constitute a waiver of or acquiescence in the Event of Default. All remedies are
cumulative to the extent permitted by law.

Section 6.04. WAIVER OF PAST DEFAULTS; RESCISSION OF ACCELERATION.

Holders of a majority in aggregate principal amount of the then outstanding
Securities of all series affected (treating all such series as a single class)
may, by notice to the Trustee, on behalf of the Holders of all of the Securities
of all such series, waive an existing Default or Event of Default and its
consequences hereunder (including in connection with an offer to purchase or
exchange), except a continuing Default or Event of Default in the payment of the
principal of, premium, if any, interest on, or any sinking fund payment with
respect to, the Securities of such series, and except a continuing Default or
Event of Default under any provision of this Indenture that, under Section 9.02,
cannot be modified or waived without the consent of a greater number of Holders
or of each Holder affected. Upon any such waiver, such Default or Event of
Default shall be deemed to have been cured for every purpose of this Indenture;
but no such waiver shall extend to any subsequent or other Default or Event of
Default or impair any right consequent

                                       26
<Page>

thereon. The Holders of a majority in aggregate principal amount of the then
outstanding Securities of all series affected (treating all such series as a
single class) may also rescind an acceleration and its consequences with respect
to all such series, including any related payment default that resulted from
such acceleration, but not including any other payment default.

Section 6.05. CONTROL BY MAJORITY.

Holders of a majority in principal amount of the then outstanding Securities of
all series with respect to which an Event of Default shall have occurred and be
continuing (treating all such series as a single class) may direct the time,
method and place of conducting any proceeding for exercising any remedy
available to the Trustee or exercising any trust or power conferred on it;
provided that

     (i)    such direction shall not be in conflict with any law or rule or with
            this Indenture;

     (ii)   the Trustee may take any other action deemed proper by the Trustee
            which is not inconsistent with such direction; and

     (iii)  the Trustee need not take any action which might involve it in
            personal liability or be unduly prejudicial to the Holders of
            Securities of such series not joining therein.

Section 6.06. LIMITATION ON SUITS.

A Holder of a Security of any series may pursue a remedy with respect to this
Indenture or the Securities of such series only if:

(a)  the Holder of a Security of any or all series affected gives to the Trustee
     written notice of a continuing Event of Default;

(b)  the Holders of at least 25% in principal amount of the then outstanding
     Securities of all affected series (treating all such series as a single
     class) make a written request to the Trustee to pursue the remedy;

(c)  such Holder or Holders offer and, if requested, provide to the Trustee
     indemnity satisfactory to the Trustee against any loss, liability or
     expense;

(d)  the Trustee does not comply with the request within 30 days after receipt
     of the request and the offer and, if requested, the provision of indemnity;
     and

(e)  during such 30-day period the Holders of a majority in principal amount of
     the then outstanding Securities of all such series (treating all such
     series as a single class) do not give the Trustee a direction inconsistent
     with the request.

A Holder of a Security may not use this Indenture to prejudice the rights of
another Holder of a Security or to obtain a preference or priority over another
Holder of a Security.

                                       27

Section 6.07. RIGHTS OF HOLDERS OF SECURITIES TO RECEIVE PAYMENT.

Notwithstanding any other provision of this Indenture, the right of any Holder
of a Security of any series to receive payment of principal, premium, if any,
and interest on such Security, on or after the respective due dates expressed in
such Security (including in connection with an offer to purchase), or to bring
suit for the enforcement of any such payment on or after such respective dates,
shall not be impaired or affected without the consent of such Holder.

Section 6.08. COLLECTION SUIT BY TRUSTEE.

If an Event of Default specified in Section 6.01(a) or (b) occurs and is
continuing with respect to any series of Securities, the Trustee is authorized
to recover judgment in its own name and as Trustee of an express trust against
the Company for the whole amount of principal of, premium, if any, and interest
remaining unpaid on such Securities and interest on overdue principal and, to
the extent lawful, interest and such further amount as shall be sufficient to
cover the costs and expenses of collection, including the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel.

Section 6.09. TRUSTEE MAY FILE PROOFS OF CLAIM.

The Trustee is authorized 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 the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel) and the
Holders of the Securities of any series allowed in any judicial proceedings
relative to the Company (or any other obligor upon the Securities), its
creditors or its property and shall be entitled and empowered to collect,
receive and distribute any money or other property payable or deliverable on any
such claims and any custodian in any such judicial proceeding is hereby
authorized by each Holder 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
Holders, to pay to the Trustee any amount due to it for the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel, and any other amounts due the Trustee under Section 7.07 hereof. To
the extent that the payment of any such compensation, expenses, disbursements
and advances of the Trustee, its agents and counsel, and any other amounts due
the Trustee under Section 7.07 hereof out of the estate in any such proceeding,
shall be denied for any reason, payment of the same shall be secured by a lien
on, and shall be paid out of, any and all distributions, dividends, money,
securities and other properties that the Holders may be entitled to receive in
such proceeding whether in liquidation or under any plan of reorganization or
arrangement or otherwise. Nothing herein contained shall be deemed to authorize
the Trustee to authorize or consent to or accept or adopt on behalf of any
Holder any plan of reorganization, arrangement, adjustment or composition
affecting the Securities of any series or the rights of any Holder, or to
authorize the Trustee to vote in respect of the claim of any Holder in any such
proceeding.

Section 6.10. PRIORITIES.

If the Trustee collects any money or other property pursuant to this Article, it
shall pay out the money or other property in the following order:

FIRST: to the Trustee, its agents and attorneys for amounts due under Section
7.07 hereof, including payment of all compensation, expense and liabilities
incurred, and all advances made, by the Trustee and the costs and expenses of
collection;

SECOND: to Holders of Securities for amounts due and unpaid on the Securities
for principal, premium, if any, interest and any other amounts, ratably, without
preference or priority of any kind, according to the amounts due and payable on
the Securities for principal, premium, if any, interest and other amounts,
respectively; and

THIRD: to the Company or to such party as a court of competent jurisdiction
shall direct.

The Trustee may fix a record date and payment date for any payment to Holders of
Securities pursuant to this Section 6.10.

Section 6.11. UNDERTAKING FOR COSTS.

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 a
Trustee, a court in its discretion may require the filing by any party litigant
in the suit of an undertaking to pay the costs of the suit, and the court in its
discretion may assess reasonable costs, including reasonable attorneys' fees,
against any party litigant in the suit, having due regard to the merits and good
faith of the claims or defenses made by the party litigant. This Section does
not apply to a suit by the Trustee, a suit by a Holder of a Security pursuant to
Section 6.07 hereof, or a suit by Holders of more than 10% in principal amount
of the then outstanding Securities of any series.

                                     TRUSTEE

Section 7.01. DUTIES OF TRUSTEE.

(a)  If an Event of Default has occurred and is continuing, the Trustee shall
     exercise such of the rights and powers vested in it by this Indenture or an
     indenture supplemental hereto, and use the same degree of care and skill in
     its exercise, as a prudent person would exercise or use under the
     circumstances in the conduct of its own affairs.

(b)  Except during the continuance of an Event of Default:

     (i)    the duties of the Trustee shall be determined solely by the express
            provisions of this Indenture or an indenture supplemental hereto,
            and the Trustee need perform only those duties that are specifically
            set forth in this Indenture or an indenture supplemental hereto and
            no others, and no implied covenants or obligations shall be read
            into this Indenture or an indenture supplemental hereto against the
            Trustee; and

                                       29
<Page>

     (ii)   in the absence of bad faith on its part, the Trustee may
            conclusively rely, as to the truth of the statements and the
            correctness of the opinions expressed therein, upon certificates or
            opinions furnished to the Trustee and conforming to the requirements
            of this Indenture. However, the Trustee shall examine the
            certificates and opinions to determine whether or not they conform
            to the requirements of this Indenture.

(c)  The Trustee may not be relieved from liabilities for its own negligent
     action, its own negligent failure to act, or its own willful misconduct,
     except that:

     (i)    this paragraph does not limit the effect of paragraph (b) of this
            Section;

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

     (iii)  the Trustee shall not be liable with respect to any action it takes
            or omits to take in good faith in accordance with a direction
            received by it pursuant to Section 6.05 hereof.

(d)  Whether or not therein expressly so provided, every provision of this
     Indenture that in any way relates to the Trustee is subject to paragraphs
     (a), (b), and (c) of this Section.

(e)  No provision of this Indenture shall require the Trustee to expend or risk
     its own funds or incur any liability. The Trustee shall be under no
     obligation to exercise any of its rights and powers under this Indenture at
     the request of any Holders, unless such Holders shall have offered to the
     Trustee security and indemnity satisfactory to it against any loss,
     liability or expense.

(f)  The Trustee shall not be liable for interest on any money received by it
     except as the Trustee may agree in writing with the Company. Money held in
     trust by the Trustee need not be segregated from other funds except to the
     extent required by law.

Section 7.02. RIGHTS OF TRUSTEE.

(a)  The Trustee may conclusively rely upon any document believed by it to be
     genuine and to have been signed or presented by the proper Person. The
     Trustee need not investigate any fact or matter stated in the document.

(b)  Before the Trustee acts or refrains from acting, it may require an
     Officers' Certificate or an Opinion of Counsel or both. The Trustee shall
     not be liable for any action it takes or omits to take in good faith in
     reliance on such Officers' Certificate or Opinion of Counsel. The Trustee
     may consult with counsel, and the written advice of such counsel or any
     Opinion of Counsel shall be full and complete authorization and protection
     from liability in respect of any action taken, suffered or omitted by it
     hereunder in good faith and in reliance thereon.

                                       30
<Page>

(c)  The Trustee may act through its attorneys and agents and shall not be
     responsible for the misconduct or negligence of any agent appointed with
     due care.

(d)  The Trustee shall not be liable for any action it takes or omits to take in
     good faith that it believes to be authorized or within the rights or powers
     conferred upon it by this Indenture.

(e)  Unless otherwise specifically provided in this Indenture, any demand,
     request, direction or notice from the Company shall be sufficient if signed
     by an Officer of the Company.

(f)  The Trustee shall be under no obligation to exercise any of the rights or
     powers vested in it by this Indenture at the request or direction of any of
     the Holders unless such Holders shall have offered to the Trustee
     reasonable security or indemnity satisfactory to it against the costs,
     expenses and liabilities that might be incurred by it in compliance with
     such request or direction.

Section 7.03. INDIVIDUAL RIGHTS OF TRUSTEE.

The Trustee in its individual or any other capacity may become the owner or
pledgee of Securities and may otherwise deal with the Company or any Affiliate
of the Company with the same rights it would have if it were not Trustee.
However, in the event that the Trustee acquires any conflicting interest (within
the meaning of TIA ss. 310(b)) it must eliminate such conflicting interest
within 90 days after Default, apply to the SEC for permission to continue as
trustee, or resign. Any Agent may do the same with like rights and duties.

Section 7.04. TRUSTEE'S DISCLAIMER.

The Trustee shall not be responsible for and makes no representation as to the
validity or adequacy of this Indenture or the Securities; it shall not be
accountable for the Company's use of the proceeds from the Securities or any
money paid to the Company or upon the Company's direction under any provision of
this Indenture; it shall not be responsible for the use or application of any
money received by any Paying Agent other than the Trustee; and it shall not be
responsible for any statement or recital herein or any statement in the
Securities or any other document in connection with the sale of the Securities
or pursuant to this Indenture other than its certificate of authentication.

Section 7.05. NOTICE OF DEFAULTS.

If a Default or Event of Default occurs and is continuing and if a Responsible
Officer of the Trustee has actual knowledge of such Default or Event of Default,
the Trustee shall mail to Holders of Securities a notice of the Default or Event
of Default within 90 days after it occurs. Except in the case of a Default or
Event of Default in payment of principal of, or interest on, any Security, the
Trustee may withhold the notice if and so long as a committee of its Responsible
Officers in good faith determines that withholding the notice is in the
interests of the Holders of the Securities.

Section 7.06. REPORTS BY TRUSTEE TO HOLDERS OF THE SECURITIES.

On or before July 31 of each year, beginning with the July 31 following the date
on which Securities are first issued under this Indenture, and for so long as
Securities remain outstanding, the Trustee shall mail to the Holders of the
Securities a brief report dated as of such reporting date that complies with TIA
ss. 313(a) (but if no event described in TIA ss. 313(a) has occurred within the
twelve months preceding the reporting date, no report need be transmitted). The
Trustee also shall comply with TIA ss. 313(b)(2). The Trustee shall also
transmit by mail all reports as required by TIA ss. 313(c). A copy of each
report at the time of its mailing to the Holders of Securities shall be mailed
to the Company and filed with the SEC and each stock exchange on which the
Securities are listed in accordance with TIA ss. 313(d). The Company shall
promptly notify the Trustee when the Securities are listed on any stock
exchange.

Section 7.07. COMPENSATION AND INDEMNITY.

The Company shall pay to the Trustee from time to time such compensation for its
acceptance of this Indenture and services hereunder as the Company and Trustee
have separately agreed. The Trustee's compensation shall not be limited by any
law on compensation of a trustee of an express trust. The Company shall
reimburse the Trustee promptly upon request for all reasonable disbursements,
advances and expenses incurred or made by it in addition to the compensation for
its services. Such expenses shall include the reasonable compensation,
disbursements and expenses of the Trustee's agents and counsel.

The Company shall indemnify the Trustee against any and all losses, liabilities
or expenses incurred by it arising out of or in connection with the acceptance
or administration of its duties under this Indenture, including the costs and
expenses of enforcing this Indenture against the Company (including this Section
7.07) and defending itself against any claim (whether asserted by the Company or
any Holder or any other person) or liability in connection with the exercise or
performance of any of its powers or duties hereunder, except to the extent any
such loss, liability or expense may be attributable to its negligence or willful
misconduct. The Trustee shall notify the Company promptly of any claim for which
it may seek indemnity. Failure by the Trustee to so notify the Company shall not
relieve the Company of its obligations hereunder. The Company shall defend the
claim, and the Trustee shall cooperate in the defense. The Trustee may have
separate counsel, and the Company shall pay the reasonable fees and expenses of
such counsel. The Company need not pay for any settlement made without its
consent, which consent shall not be unreasonably withheld.

The obligations of the Company under this Section 7.07 shall survive the
satisfaction and discharge of this Indenture, and the removal or resignation of
the Trustee.

To secure the Company's payment obligations in this Section, the Trustee shall
have a lien prior to the Securities on all money or property held or collected
by the Trustee, except that held in trust to pay principal of, premium, if any,
and interest on particular Securities. Such lien shall survive the satisfaction
and discharge of this Indenture.

When the Trustee incurs expenses or renders services after an Event of Default
specified in Section 6.01(e) or (f) hereof occurs, the expenses and the
compensation for the services

                                       32
<Page>

(including the fees and expenses of its agents and counsel) are intended to
constitute expenses of administration under any Bankruptcy Law.

Section 7.08. REPLACEMENT OF TRUSTEE.

A resignation or removal of the Trustee and appointment of a successor Trustee
shall become effective only upon the successor Trustee's acceptance of
appointment as provided in this Section.

The Trustee may resign with respect to one or more or all series of Securities
at any time and be discharged from the trust hereby created by so notifying the
Company in writing. The Holders of a majority in principal amount of the then
outstanding Securities of any series may remove the Trustee with respect to such
series by so notifying the Trustee and the Company in writing. The Company may
remove the Trustee if:

(a)  the Trustee ceases to be eligible in accordance with Section 7.10 hereof;

(b)  the Trustee is adjudged bankrupt or insolvent or an order for relief is
     entered with respect to the Trustee under any Bankruptcy Law;

(c)  a custodian or public officer takes charge of the Trustee or its property;
     or

(d)  the Trustee becomes incapable of acting.

If the Trustee resigns or is removed or if a vacancy exists in the office of
Trustee for any reason, the Company shall promptly appoint a successor Trustee.
Within one year after the successor Trustee takes office, the Holders of a
majority in principal amount of the then outstanding Securities of a series may
appoint a successor Trustee to replace the successor Trustee appointed by the
Company with respect to that series of Securities.

If a successor Trustee does not take office within 60 days after the retiring
Trustee resigns or is removed, the retiring Trustee, the Company, or the Holders
of at least 10% in principal amount of the then outstanding Securities may
petition any court of competent jurisdiction for the appointment of a successor
Trustee.

If the Trustee, after written request by any Holder of a Security who has been a
Holder of a Security for at least six months, ceases to be eligible in
accordance with Section 7.10, such Holder of a Security may petition any court
of competent jurisdiction for the removal of the Trustee and the appointment of
a successor Trustee.

A successor Trustee shall deliver a written acceptance of its appointment to the
retiring Trustee and to the Company. Thereupon, the resignation or removal of
the retiring Trustee shall become effective, and the successor Trustee shall
have all the rights, powers and duties of the Trustee under this Indenture. The
successor Trustee shall mail a notice of its succession to Holders of the
Securities. The retiring Trustee shall promptly transfer all property held by it
as Trustee to the successor Trustee, PROVIDED all sums owing to the Trustee
hereunder have been paid and subject to the lien provided for in Section 7.07
hereof. Notwithstanding replacement of the

                                       33
<Page>

Trustee pursuant to this Section 7.08, the Company's obligations under Section
7.07 hereof shall continue for the benefit of the retiring Trustee.

If a successor Trustee is appointed with respect to the Securities of one or
more (but not all) series, the Company, the retiring Trustee and each successor
Trustee with respect to the Securities of any applicable series shall execute
and deliver an indenture supplemental hereto which shall contain such provisions
as shall be deemed necessary or desirable to confirm that all the rights,
powers, trusts and duties of the retiring Trustee with respect to the Securities
of any series as to which the predecessor Trustee is not retiring shall continue
to be vested in the predecessor Trustee, and shall add to or change any of the
provisions of this Indenture as shall be necessary to provide for or facilitate
the administration of the trusts hereunder by more than one Trustee, it being
understood that nothing herein or in such supplemental indenture shall
constitute such Trustees as co-trustees of the same trust and that each such
Trustee shall be Trustee of a trust or trusts hereunder separate and apart from
any trust or trusts hereunder administered by any other such Trustee.

Section 7.09. SUCCESSOR TRUSTEE BY MERGER, ETC.

If the Trustee consolidates, merges or converts into, or transfers all or
substantially all of its corporate trust business to, another corporation, the
successor corporation without any further act shall be the successor Trustee.

Section 7.10. ELIGIBILITY; DISQUALIFICATION.

There shall at all times be a Trustee hereunder that is a corporation organized
and doing business under the laws of the United States of America or of any
state thereof that is authorized under such laws to exercise corporate trust
powers, that is subject to supervision or examination by federal or state
authorities and that has a combined capital and surplus of at least $50,000,000
as set forth in its most recent published annual report of condition.

This Indenture shall always have a Trustee who satisfies the requirements of
TIAss. 310(a)(1), (2) and (5). The Trustee is subject to TIAss. 310(b).

Section 7.11. PREFERENTIAL COLLECTION OF CLAIMS AGAINST COMPANY.

The Trustee is subject to TIA ss. 311(a), excluding any creditor relationship
described in TIA ss. 311(b). A Trustee who has resigned or been removed shall be
subject to TIA ss. 311(a) to the extent indicated therein.

                                   ARTICLE 8.
                    LEGAL DEFEASANCE AND COVENANT DEFEASANCE

Section 8.01. OPTION TO EFFECT LEGAL DEFEASANCE OR COVENANT DEFEASANCE.

(a)  The Company may, at the option of its Board of Directors evidenced by a
     resolution set forth in an Officers' Certificate, at any time, elect to
     have either Section 8.02 or 8.03

                                       34
<Page>

     hereof, with such modifications thereto as may be specified in the Board
     Resolution or supplemental indenture establishing a particular series of
     Securities, be applied to all outstanding Securities of one or more series
     upon compliance with the conditions set forth below in this Article 8.

(b)  As an alternative to having Section 8.02 or 8.03 be applied to all
     outstanding Securities of one or more series, the Company may terminate its
     obligations under the Securities of one or more series and its obligations
     under this Indenture in respect of such series of Securities (except those
     obligations referred to in the penultimate paragraph of this Section
     8.01(b), and any obligation of the Company to convert or exchange
     Securities of such series as expressly provided for in the Board Resolution
     or indenture supplemental hereto establishing such Series) (1) if (i) all
     Securities of such series theretofore authenticated and delivered (except
     lost, stolen or destroyed Securities that have been replaced or paid and
     Securities for whose payment cash in United States dollars has theretofore
     been deposited in trust or segregated and held in trust by the Company and
     thereafter repaid to the Company or discharged from such trust as provided
     in Section 8.06) have been delivered to the Trustee for cancellation; (ii)
     the Company has paid all sums payable by it hereunder or under the
     applicable Board Resolution or indenture supplemental hereto in respect of
     such series of Securities; and (iii) the Company shall have delivered to

     stating that all conditions precedent relating to the satisfaction and
     discharge of this Indenture have been complied with; or (2) if (i) either
     (A) in the case of a series of Securities redeemable prior to its stated
     maturity, the Company shall, pursuant to Article 3, have given notice to
     the Trustee and mailed a notice of redemption to each Holder of Securities
     of such series of the redemption of all of such Securities under
     arrangements satisfactory to the Trustee for the giving of such notice or
     (B) all Securities of such series have otherwise become due and payable
     hereunder or will become due and payable within one year; (ii) the Company
     shall have irrevocably deposited or caused to be deposited with the Trustee
     (or a trustee satisfactory to the Trustee, under the terms of an
     irrevocable trust agreement in form and substance satisfactory to the
     Trustee), as trust funds in trust solely for the benefit of the Holders of
     Securities of such series for that purpose, cash in United States dollars
     in such amount as is sufficient without consideration of reinvestment of
     interest or other earnings on such cash, to pay the entire indebtedness on
     such Securities not theretofore delivered to the Trustee for cancellation,
     for the principal of, premium, if any, and interest on the outstanding
     Securities of such series to the date of such deposit (in the case of
     Securities which have become due and payable) or to the stated maturity or
     redemption date, as the case may be; (iii) no Default or Event of Default
     with respect to this Indenture or the Securities shall have occurred and be
     continuing on the date of such deposit or shall occur as a result of such
     deposit and such deposit will not result in a breach or violation of, or
     constitute a default under, any other instrument to which the Company is
     bound; (iv) the Company shall have paid all other sums payable by it
     hereunder in respect of Securities of such series; and (v) the Company
     shall have delivered to the Trustee an Officers' Certificate and an Opinion
     of Counsel, each stating that all conditions precedent relating to the
     satisfaction and discharge of this Indenture have been complied with.

                                       35
<Page>

Notwithstanding the foregoing paragraph, the Company's obligations in Sections
2.07, 2.08, 2.09, 2.10, 4.01, including any provision of the applicable Board
Resolution or indenture supplemental hereto relating to the payment of
principal, premium or interest, 4.02, 7.07, 8.06 and 8.07 shall survive with
respect to the Securities of the applicable series until they are no longer
outstanding pursuant to the last paragraph of Section 2.10. After the Securities
of the applicable series are no longer outstanding, the Issuer's obligations in
Sections 7.07, 8.06 and 8.07 shall survive in respect of Securities of the
applicable series.

After such delivery or irrevocable deposit, the Trustee upon request shall
acknowledge in writing the discharge of the Company's obligations under the
Securities of the applicable series and the Company's obligations under this
Indenture with respect to the Securities of such series, except for those
surviving obligations specified above.

Section 8.02. LEGAL DEFEASANCE AND DISCHARGE.

Upon the Company's exercise under Section 8.01 hereof of the option applicable
to this Section 8.02 relating to one or more series of Securities, the Company
shall, upon the satisfaction of the conditions set forth in Section 8.04 hereof,
be deemed to have been discharged from its obligations with respect to all
outstanding Securities of such series on the date the conditions set forth below
are satisfied (hereinafter, "LEGAL DEFEASANCE"). For this purpose, Legal
Defeasance means that the Company shall be deemed to have paid and discharged
the entire indebtedness represented by the outstanding Securities of the
applicable series, which shall thereafter be deemed to be "OUTSTANDING" only for
the purposes of Section 8.05 hereof and the other Sections of this Indenture
referred to in (a) and (b) below, and to have satisfied all of its other
obligations under the Securities of the applicable series and under the
provisions of this Indenture applicable to such series (and the Trustee, on
demand of and at the expense of the Company, shall execute proper instruments
acknowledging the same), except for the following provisions which shall survive
until otherwise terminated or discharged hereunder: (a) the rights of Holders of
outstanding Securities of the applicable series to receive solely from the trust
fund described in Section 8.04 hereof, and as more fully set forth in such
Section, payments in respect of the principal of, premium, if any, and interest,
on such Securities when such payments are due, (b) the Company's obligations
with respect to such Securities under Article 2 and Section 4.02 hereof, (c) the
rights, powers, trusts, duties and immunities of the Trustee hereunder, and the
Company's obligations in connection therewith and (d) this Article 8. Subject to
compliance with this Article 8, the Company may exercise its option under this
Section 8.02 notwithstanding the prior exercise of its option under Section 8.03
hereof.

Section 8.03. COVENANT DEFEASANCE.

Upon the Company's exercise under Section 8.01 hereof of the option applicable
to this Section 8.03 relating to one or more series of Securities, the Company
shall, upon the satisfaction of the conditions set forth in Section 8.04 hereof,
be released from its obligations under the covenants contained in Sections 4.03,
4.04, 4.05 and 4.06 hereof with respect to the outstanding Securities of the
applicable series, and under any other covenants specified in the supplemental
indenture or other terms of the applicable series as covenants to which this
Section 8.03 apply, on and after the date the conditions set forth below are
satisfied (hereinafter, "COVENANT DEFEASANCE"), and the Securities of the
applicable series shall thereafter be deemed not

                                       36
<Page>

"OUTSTANDING" for the purposes of any direction, waiver, consent or declaration
or act of Holders (and the consequences of any thereof) in connection with such
covenants, but shall continue to be deemed "OUTSTANDING" for all other purposes
hereunder (it being understood that the Securities of the applicable series
shall not be deemed outstanding for accounting purposes). For this purpose,
Covenant Defeasance means that, with respect to the "OUTSTANDING" Securities of
the applicable series, the Company may omit to comply with and shall have no
liability in respect of any term, condition or limitation set forth in any such
covenant, whether directly or indirectly, by reason of any reference elsewhere
herein to any such covenant or by reason of any reference in any such covenant
to any other provision herein or in any other document and such omission to
comply shall not constitute a Default or an Event of Default under Section 6.01
hereof, but, except as specified above, the remainder of this Indenture and such
Securities shall be unaffected thereby.

Section 8.04. CONDITIONS TO LEGAL OR COVENANT DEFEASANCE.

The following shall be the conditions to the application of either Section 8.02
or 8.03 hereof to the outstanding Securities of one or more series:

In order to exercise either Legal Defeasance or Covenant Defeasance:

(a)  the Company must irrevocably deposit with the Trustee, (or another trustee
     satisfying the requirements of Section 7.10, who shall agree to comply with
     the provisions of this Article 8 applicable to it) in trust, for the
     benefit of the Holders of the Securities of the applicable series, (i) an
     amount of cash in United States dollars, (ii) non-callable U.S. Government
     Obligations which, through scheduled payment of principal and interest in
     respect thereof in accordance with their terms, will provide, not later
     than one Business Day before the due date of any payment of principal of,
     premium, if any, or interest on the Securities of such series, cash in an
     amount, or (iii) a combination thereof, sufficient, in the opinion of a
     nationally recognized firm of independent public accountants, to pay the
     principal of, interest and premium, if any, on the outstanding Securities
     of the applicable series on the Stated Maturity or on the applicable
     redemption date, as the case may be, and any mandatory sinking fund
     payments applicable to the Securities of such series on the day on which
     such payments are due, and the Company must specify whether the Securities
     of the applicable series are being defeased to maturity or to a particular
     redemption date;

(b)  in the case of an election under Section 8.02 hereof, the Company shall
     have delivered to the Trustee an Opinion of Counsel in the United States
     reasonably acceptable to the Trustee confirming that (i) the Company has
     received from, or there has been published by, the Internal Revenue Service
     a ruling or (ii) since the date of this Indenture, there has been a change
     in the applicable federal income tax law, in either case to the effect
     that, and based thereon such Opinion of Counsel shall confirm that, the
     Holders of the outstanding Securities of the applicable series will not
     recognize income, gain or loss for federal income tax purposes as a result
     of such Legal Defeasance and will be subject to federal income tax on the
     same amounts, in the same manner and at the same times as would have been
     the case if such Legal Defeasance had not occurred;

                                       37
<Page>

(c)  in the case of an election under Section 8.03 hereof, the Company shall
     have delivered to the Trustee an Opinion of Counsel in the United States
     reasonably acceptable to the Trustee confirming that the Holders of the
     outstanding Securities of the applicable series will not recognize income,
     gain or loss for federal income tax purposes as a result of such Covenant
     Defeasance and will be subject to federal income tax on the same amounts,
     in the same manner and at the same times as would have been the case if
     such Covenant Defeasance had not occurred;

(d)  no Default or Event of Default shall have occurred and be continuing on the
     date of such deposit (other than a Default or Event of Default resulting
     from the borrowing of funds to be applied to such deposit) or insofar as
     Sections 6.01(e) or (f) hereof are concerned, at any time in the period
     ending on the 91st day after the date of deposit (or greater period of time
     in which any such deposit of trust funds may remain subject to bankruptcy
     or insolvency laws insofar as those apply to the deposit by the Company);

(e)  the Company shall have delivered to the Trustee an Officers' Certificate
     and an Opinion of Counsel, each stating that all conditions precedent
     provided for or relating to the Legal Defeasance or the Covenant Defeasance
     have been complied with.

Section 8.05. DEPOSITED MONEY AND U.S. GOVERNMENT OBLIGATIONS TO BE HELD IN
              TRUST; OTHER MISCELLANEOUS PROVISIONS.

Subject to Section 8.06 hereof, all money and non-callable U.S. Government
Obligations (including the proceeds thereof) deposited with the Trustee (or
other qualifying trustee, collectively for purposes of this Section 8.05, the
"TRUSTEE") pursuant to Section 8.04 hereof in respect of the outstanding
Securities of the applicable series shall be held in trust and applied by the
Trustee, in accordance with the provisions of such Securities and this
Indenture, to the payment, either directly or through any Paying Agent
(including the Company acting as Paying Agent) as the Trustee may determine, to
the Holders of such Securities of all sums due and to become due thereon in
respect of principal, premium, if any, and interest, but such money need not be
segregated from other funds except to the extent required by law.

The Company shall pay and indemnify the Trustee against any tax, fee or other
charge imposed on or assessed against the cash or non-callable U.S. Government
Obligations deposited pursuant to Section 8.04 hereof or the principal and
interest received in respect thereof other than any such tax, fee or other
charge which by law is for the account of the Holders of the outstanding
Securities of the applicable series.

Anything in this Article 8 to the contrary notwithstanding, the Trustee shall
deliver or pay to the Company from time to time upon the request of the Company
any money or non-callable U.S. Government Obligations held by it as provided in
Section 8.04 hereof which, in the opinion of a nationally recognized firm of
independent public accountants expressed in a written certification thereof
delivered to the Trustee (which may be the opinion delivered under Section
8.04(a) hereof), are in excess of the amount thereof that would then be required
to be deposited to effect an equivalent Legal Defeasance or Covenant Defeasance
of the applicable series.

                                       38
<Page>

Section 8.06. REPAYMENT TO COMPANY.

Any money and U.S. Government Obligations deposited with the Trustee or any
Paying Agent, or then held by the Company, in trust for the payment of the
principal of, premium or interest on any Security and remaining unclaimed for
two years after such principal, and premium, if any, or interest has become due
and payable shall be paid to the Company on its request or (if then held by the
Company) shall be discharged from such trust; and the Holder of such Security
shall thereafter look only to the Company for payment thereof, and all liability
of the Trustee or such Paying Agent with respect to such money and U.S.
Government Obligations, and all liability of the Company as trustee thereof,
shall thereupon cease; PROVIDED, HOWEVER, that the Trustee or such Paying Agent,
before being required to make any such repayment, may at the expense of the
Company cause to be published once, in the NEW YORK TIMES and THE WALL STREET
JOURNAL (national edition), notice that such money remains unclaimed and that,
after a date specified therein, which shall not be less than 30 days from the
date of such notification or publication, any unclaimed balance of such money
then remaining will be repaid to the Company.

Section 8.07. REINSTATEMENT.

If the Trustee or Paying Agent is unable to apply any United States dollars or
non-callable U.S. Government Obligations deposited pursuant to Section 8.02 or
8.03 hereof, as the case may be, by reason of any order or judgment of any court
or governmental authority enjoining, restraining or otherwise prohibiting such
application, then the obligations of the Company under this Indenture and the
Securities shall be revived and reinstated as though no deposit had occurred
pursuant to Section 8.02 or 8.03 hereof until such time as the Trustee or Paying
Agent is permitted to apply all such money in accordance with Section 8.02 or
8.03 hereof, as the case may be; PROVIDED, HOWEVER, that, if the Company makes
any payment of principal of, premium or interest on any Security following the
reinstatement of its obligations, the Company shall be subrogated to the rights
of the Holders of such Securities to receive such payment from the money held by
the Trustee or Paying Agent.

                                   ARTICLE 9.
                        AMENDMENT, SUPPLEMENT AND WAIVER

Section 9.01. WITHOUT CONSENT OF HOLDERS OF SECURITIES.

Notwithstanding Section 9.02 of this Indenture, the Company and the Trustee may
amend or supplement this Indenture or the Securities without the consent of any
Holder of a Security:

(a)  to evidence the succession of another Person to the Company, or successive
     successions, and the assumption by the successor Person of the covenants,
     agreements and obligations of the Company pursuant to Article 5 hereof;

(b)  to add to the covenants of the Company such further covenants, restrictions
     or conditions for the protection of the Holders of all or any series of
     Securities (and if such covenants are to be for the benefit of less than
     all series of Securities stating that such covenants are expressly being
     included for the benefit of such series) as the Board of Directors and the

                                       39
<Page>

     Trustee shall consider to be for the protection of the Holders of such
     Securities, and to make the occurrence, or the occurrence and continuance,
     of a default in any of such additional covenants, restrictions or
     conditions a default or an Event of Default permitting the enforcement of
     all or any of the several remedies provided in this Indenture as herein set
     forth; provided, however, that in respect of any such additional covenant,
     restriction or condition such supplemental indenture may provide for a
     particular period of grace after default (which period may be shorter or
     longer than that allowed in the case of other defaults) or may provide for
     an immediate enforcement upon such default or may limit the remedies
     available to the Trustee upon such default;

(c)  to provide for the issuance under this Indenture of Securities in coupon
     form (including Securities registrable as to principal only) and to provide
     for exchangeability of such Securities with the Securities issued hereunder
     in fully registered form and to make all appropriate changes for such
     purpose;

(d)  to cure any ambiguity or to correct or supplement any provision contained
     herein or in any supplemental indenture which may be defective or
     inconsistent with any other provision contained herein or in any
     supplemental indenture, or to make such other provisions in regard to
     matters or questions arising under this Indenture; provided that any such
     action shall not adversely affect the interests of the Holders of the
     Securities;

(e)  to evidence and provide for the acceptance of appointment hereunder by a
     successor trustee with respect to the Securities of one or more series and
     to add to or change any of the provisions of this Indenture as shall be
     necessary to provide for or facilitate the administration of the trusts
     hereunder by more than one trustee, pursuant to the requirements of Section
     7.08;

(f)  to make any change that does not adversely affect the rights of any Holder;
     or

(g)  to provide for the issuance of and establish the form and terms and
     conditions of the Securities of any series, to establish the form of any
     certifications required to be furnished pursuant to the terms of this
     Indenture or any series of Securities, or to add to the rights of the
     Holders of any series of Securities.

Upon the request of the Company accompanied by a copy of a Board Resolution,
certified by the Secretary or an Assistant Secretary of the Company to have been
duly adopted by the Board of Directors and to be in full force and effect on the
date of the certificate, authorizing the execution of any such amended or
supplemental indenture, and upon receipt by the Trustee of the documents
described in Section 7.02 hereof, the Trustee shall join with the Company in the
execution of any amended or supplemental indenture authorized or permitted by
the terms of this Indenture and to make any further appropriate agreements and
stipulations that may be therein contained, but the Trustee shall not be
obligated to enter into such amended or supplemental indenture that affects its
own rights, duties or immunities under this Indenture or otherwise.

Section 9.02. WITH CONSENT OF HOLDERS OF SECURITIES.

Except as provided below in this Section 9.02, the Company and the Trustee may
amend or supplement this Indenture, or the Securities of any series may be
amended or supplemented, with

                                       40
<Page>

the consent of the Holders of a majority in principal amount of the Securities
then outstanding of all series affected by such supplemental indenture (voting
as a single class) (including, without limitation, consents obtained in
connection with a purchase of, or tender offer or exchange offer for,
Securities), and, subject to Sections 6.04 and 6.07 hereof, any existing Default
or Event of Default (other than a Default or Event of Default in the payment of
the principal of, premium or interest on the Securities) or compliance with any
provision of this Indenture or the Securities of such series may be waived with
the consent of the Holders of a majority in principal amount of the Securities
then outstanding of all series affected by such waiver (voting as a single
class) (including, without limitation, consents obtained in connection with a
purchase of, or tender offer or exchange offer for the Securities).

Upon the request of the Company accompanied by a copy of a Board Resolution,
certified by the Secretary or an Assistant Secretary of the Company to have been
duly adopted by the Board of Directors and to be in full force and effect on the
date of the certificate, authorizing the execution of any such amended or
supplemental indenture, and upon the filing with the Trustee of evidence
satisfactory to the Trustee of the consent of the Holders of Securities of each
such series as aforesaid, and upon receipt by the Trustee of the documents
described in Section 7.02(b) hereof, the Trustee shall join with the Company in
the execution of such amended or supplemental indenture unless such amended or
supplemental indenture affects the Trustee's own rights, duties or immunities
under this Indenture or otherwise, in which case the Trustee may in its
discretion, but shall not be obligated to, enter into such amended or
supplemental indenture.

It shall not be necessary for the consent of the Holders of Securities under
this Section 9.02 to approve the particular form of any proposed amendment or
waiver, but it shall be sufficient if such consent approves the substance
thereof.

After an amendment, supplement or waiver under this Section 9.02 becomes
effective, the Company shall mail to the Holders of Securities of such series
affected thereby a notice briefly describing the amendment, supplement or
waiver. Any failure of the Company to mail such notice, or any defect therein,
shall not, however, in any way impair or affect the validity of any such amended
or supplemental indenture or waiver.

However, without the consent of each Holder of Securities affected, an amendment
or waiver may not (with respect to any Securities held by a non-consenting
Holder):

(a)  reduce the principal amount of the Securities whose Holders must consent to
     an amendment, supplement or waiver;

(b)  reduce the principal of or change the fixed maturity of the principal of,
     premium, if any, or mandatory sinking fund obligation, if any, with respect
     to any Securities of any series or alter the provisions with respect to the
     redemption of the Securities;

(c)  reduce the rate of or change the time for payment of interest, including
     default interest, on any Security of any series;

(d)  waive a Default or Event of Default in the payment of principal of or
     interest or premium on the Securities of any series (except a rescission of
     acceleration of the Securities by the

                                       41
<Page>

     Holders of a majority in aggregate principal amount of the Securities of
     one or more affected series and a waiver of the payment default that
     resulted from such acceleration);

(e)  make any Security of any series payable in currency other than that stated
     in the Securities of such series;

(f)  make any change in the provisions of this Indenture relating to waivers of
     past Defaults or the rights of Holders of Securities to receive payments of
     principal of or interest or premium on the Securities;

(g)  waive a redemption payment with respect to any Security; or

(h)  make any change in Section 6.04 or 6.07 hereof or in the amendment and
     waiver provisions of Section 9.01 or this Section 9.02.

Section 9.03. COMPLIANCE WITH TRUST INDENTURE ACT.

Every amendment or supplement to this Indenture or the Securities shall be set
forth in an amended or supplemental indenture that complies with the TIA as then
in effect.

Section 9.04. REVOCATION AND EFFECT OF CONSENTS.

Until an amendment, supplement or waiver becomes effective, a consent to it by a
Holder of a Security is a continuing consent by the Holder of a Security and
every subsequent Holder of a Security or portion of a Security that evidences
the same debt as the consenting Holder's Securities, even if notation of the
consent is not made on any Securities. However, any such Holder of a Security or
subsequent Holder of a Security may revoke the consent as to its Securities if
the Trustee receives written notice of revocation before the date the waiver,
supplement or amendment becomes effective. An amendment, supplement or waiver
becomes effective in accordance with its terms and thereafter binds every
Holder.

Section 9.05. NOTATION ON OR EXCHANGE OF SECURITIES.

The Trustee may place an appropriate notation about an amendment, supplement or
waiver on any Securities thereafter authenticated. The Company in exchange for
all Securities may issue and the Trustee shall authenticate new Securities that
reflect the amendment, supplement or waiver.

Failure to make the appropriate notation or to issue new Securities shall not
affect the validity and effect of such amendment, supplement or waiver.

Section 9.06. TRUSTEE TO SIGN AMENDMENTS, ETC.

The Company may not sign an amendment or supplemental indenture until its Board
of Directors approves it. The Trustee shall sign any amendment or supplemental
indenture authorized pursuant to this Article 9 if the amendment or supplement
does not adversely affect the rights, duties, liabilities or immunities of the
Trustee. If it does, the Trustee may, but need not, sign it. In signing or
refusing to sign such amendment or supplemental indenture, the Trustee shall be

                                       42
<Page>

entitled to receive and shall be fully protected in relying upon, an Officers'
Certificate and an Opinion of Counsel as conclusive evidence that such amendment
or supplemental indenture is authorized or permitted by this Indenture, that it
is not inconsistent herewith, and that it will be valid and binding upon the
Company in accordance with its terms.

                                   ARTICLE 10.

     of the Holders of Securities of such series for any purpose specified in
     Section 10.01 by written request setting forth in reasonable detail the
     action proposed to be taken at the meeting, and the Trustee shall not have
     mailed notice of such meeting within 20 days after receipt of such request
     or shall not thereafter proceed to cause the meeting to be held as provided
     herein, then the Company or the Holders of Securities of such series in the
     amount above specified, as the case may be, may determine the time and the
     place for such meeting and may call such meeting for such purposes by
     giving notice thereof as provided in clause (a) of this Section.

Section 10.04. QUORUM; ACTION.

The Persons entitled to vote a majority in principal amount of the outstanding
Securities of a series shall constitute a quorum for a meeting of Holders of
Securities of such series; provided, however, that if any action is to be taken
at such meeting with respect to a consent or waiver which this Indenture (or any
Board Resolution or indenture supplemental hereto establishing a series of
Securities hereunder) expressly provides may be given by the Holders of more or
less than a majority in principal amount of the outstanding Securities of a
series, the Persons entitled to vote such percentage in principal amount of the
outstanding Securities of such series shall constitute a quorum. In the absence
of a quorum within 30 minutes after the time appointed for any such meeting, the
meeting shall, if convened at the request of Holders of Securities of such
series, be dissolved. In any other case the meeting may be adjourned for a
period of not less than 10 days as determined by the chairman of the meeting
prior to the adjournment of such meeting. In the absence of a quorum at any such
adjourned meeting, such adjourned meeting may be further adjourned for a period
of not less than 10 days as determined by the chairman of the meeting prior to
the adjournment of such adjourned meeting. Notice of the reconvening of any such
adjourned meeting shall be given as provided in Section 10.02(a), except that
such notice need be given only once not less than five days prior to the date on
which the meeting is scheduled to be reconvened. Notice of the reconvening of an
adjourned meeting shall state expressly the percentage, as provided above, of
the principal amount of the outstanding Securities of such series which shall
constitute a quorum.

Except as otherwise provided in Section 6.02 or 9.02 (or in any Board Resolution
or indenture supplemental hereto establishing a series of Securities hereunder),
any resolution presented to a meeting or adjourned meeting duly reconvened at
which a quorum is present as aforesaid may be adopted only by the affirmative
vote of the Holders of a majority in principal amount of the outstanding
Securities of that series; provided, however, that, except as otherwise provided
in Section 6.02 or 9.02 (or in any Board Resolution or indenture supplemental
hereto establishing a series of Securities hereunder), any resolution with
respect to any request, demand, authorization, direction, notice, consent,
waiver or other action which this Indenture or any supplemental indenture
expressly provides may be made, given or taken by the Holders of a specified
percentage in principal amount of the outstanding Securities of a series may be
adopted at a meeting or an adjourned meeting duly reconvened and at which a
quorum is present as aforesaid by the affirmative vote of the Holders of such
specified percentage in principal amount of the outstanding Securities of such
series.

Any resolution passed or decision taken at any meeting of Holders of Securities
of any series duly held in accordance with this Section shall be binding on all
the Holders of Securities of such series, whether or not such Holders were
present or represented at the meeting.

Section 10.05. DETERMINATION OF VOTING RIGHTS; CONDUCT AND ADJOURNMENT OF
               MEETINGS.

(a)  Notwithstanding any other provisions of this Indenture, the Trustee may
     make such reasonable regulations as it may deem advisable for any meeting
     of Holders of Securities of a series in regard to proof of the holding of
     Securities of such series and of the appointment of proxies and in regard
     to the appointment and duties of inspectors of votes,

                                       44
<Page>

     the submission and examination of proxies, certificates and other evidence
     of the right to vote, and such other matters concerning the conduct of the
     meeting as it shall deem appropriate. Except as otherwise permitted or
     required by any such regulations, the holding of Securities shall be proved
     in the manner specified in Section 1.05 and the appointment of any proxy
     shall be proved in the manner specified in Section 1.05. Such regulations
     may provide that written instruments appointing proxies, regular on their
     face, may be presumed valid and genuine without the proof specified in
     Section 1.05 or other proof.

(b)  The Trustee shall, by an instrument in writing, appoint a temporary
     chairman of the meeting, unless the meeting shall have been called by the
     Company or by Holders of Securities as provided in Section 10.02(b), in
     which case the Company or the Holders of Securities of the series calling
     the meeting, as the case may be, shall in like manner appoint a temporary
     chairman. A permanent chairman and a permanent secretary of the meeting
     shall be elected by vote of the Persons entitled to vote at least a
     majority in principal amount of the outstanding Securities of such series
     represented at the meeting.

(c)  At any meeting each Holder of a Security of such series or proxy shall be
     entitled to one vote for each $25 principal amount of the outstanding
     Securities of such series held or represented by him; provided, however,
     that no vote shall be cast or counted at any meeting in respect of any
     Security challenged as not outstanding and ruled by the chairman of the
     meeting to be not outstanding. The chairman of the meeting shall have no
     right to vote, except as a Holder of a Security of such series or proxy.

(d)  Any meeting of Holders of Securities of any series duly called pursuant to
     Section 10.02 at which a quorum is present may be adjourned from time to
     time by Persons entitled to vote at least a majority in principal amount of
     the outstanding Securities of such series represented at the meeting; and
     the meeting may be held as so adjourned without further notice.

Section 10.06. COUNTING VOTES AND RECORDING ACTION OF MEETINGS.

(a)  The vote upon any resolution submitted to any meeting of Holders of
     Securities of any series shall be by written ballots on which shall be
     subscribed the signatures of the Holders of Securities of such series or of
     their representatives by proxy and the principal amounts and serial numbers
     of the outstanding Securities of such series held or represented by them.
     The permanent chairman of the meeting shall appoint two inspectors of votes
     who shall count all votes cast at the meeting for or against any resolution
     and who shall make and file with the secretary of the meeting their
     verified written reports in duplicate of all votes cast at the meeting. A
     record, at least in duplicate, of the proceedings of each meeting of
     Holders of Securities of any series shall be prepared by the secretary of
     the meeting and there shall be attached to said record the original reports
     of the inspectors of votes on any vote by ballot taken thereat and
     affidavits by one or more persons having knowledge of the facts setting
     forth a copy of the notice of the meeting and showing that said notice was
     given as provided in Section 10.02 and, if applicable, Section 10.04. Each
     copy shall be signed and verified by the affidavits of the permanent
     chairman and secretary of the meeting and one such copy

                                       45
<Page>

     shall be delivered to the Company, and another to the Trustee to be
     preserved by the Trustee, the latter to have attached thereto the ballots
     voted at the meeting. Any record so signed and verified shall be conclusive
     evidence of the matters therein stated.

                                                                 REDEMPTION
YEAR                                                               PRICE

and unpaid interest, to the date of redemption; provided that, after any such
redemption, the aggregate principal amount of the Notes outstanding (excluding
Notes held by the Company and its Subsidiaries) must equal at least __% of the
Notes that had been issued under the Indenture up to the time of redemption; and
provided further, that any such redemption shall occur within 90 days of the

date interest ceases to accrue on Notes or portions thereof called for
redemption.

8.   DENOMINATIONS, TRANSFER, EXCHANGE. The Notes are in registered form without
coupons in all appropriate denominations. The transfer of Notes may be

Holder to pay any taxes and fees required by law or permitted by the

<Page>

Indenture. The Company need not transfer or exchange any Note selected for
redemption, except for the unredeemed portion of any Note being redeemed in
part. Also, it need not transfer or exchange any Note for a period of 15 days
before a selection of Notes to be redeemed.

9.   PERSONS DEEMED OWNERS. The registered Holder of a Note may be treated as
its owner for all purposes.

10.  AMENDMENT, SUPPLEMENT AND WAIVER. Subject to certain exceptions, the
Indenture or the Notes may be amended or supplemented with the consent of the
Holders of a majority in principal amount of the then outstanding Notes and
other series of Securities affected (treating the Notes and such other series as
a single class), and any existing default or compliance with any provision of
the Indenture, the Notes may be waived with the consent of the Holders of a
majority in principal amount of the then outstanding Notes and other series of
Securities affected (treating the Notes and such other series as a single
class). Without the consent of any Holder of a Note, the Indenture or the Notes
may be amended or supplemented to cure any ambiguity, defect or inconsistency,
to provide for uncertificated Notes in addition to or in place of certificated
Notes, to provide for the assumption of the Company's obligations to Holders of
the Notes in case of a merger or consolidation, to make any change that would
provide any additional rights or benefits to the Holders of the Notes or that
does not adversely affect the legal rights under the Indenture of any such
Holder, or to comply with the requirements of the SEC in order to effect or
maintain the qualification of the Indenture under the TIA.

11.  DEFAULTS AND REMEDIES. Each of the following constitutes an Event of
Default: (i) default by the Company in the payment of interest on the Notes when
the same becomes due and payable and default continues for a period of 30 days;
(ii) default by the Company in the payment of the principal of or premium, if
any, on the Notes when the same becomes due and payable at maturity, upon
redemption or otherwise; (iii) failure by the Company to comply with Section
5.01 of the Indenture; (iv) failure by the Company for 60 days after notice to
comply with any of its other agreements in the Indenture or the Notes and (v)
certain events of bankruptcy or insolvency with respect to the Company. If any
Event of Default occurs and is continuing, the Trustee or the Holders of at
least 25% in principal amount of the then outstanding Notes and other series of
Securities affected (treating the Notes and such other series as a single class)
may declare all the Notes to be due and payable immediately. Notwithstanding the
foregoing, in the case of an Event of Default arising from certain events of
bankruptcy or insolvency with respect to the Company, all outstanding Notes will
become due and payable without further action or notice. Holders of the Notes
may not enforce the Indenture or the Notes except as provided in the Indenture.
Subject to certain limitations, Holders of a majority in principal amount of the
then outstanding Notes and other series of Securities affected (treating the
Notes and such other series as a single class) may direct the Trustee in its
exercise of any trust or power. The Trustee may withhold from Holders of the
Notes notice of any continuing Default or Event of Default (except a Default or
Event of Default relating to the payment of principal or interest) if it
determines that withholding notice is in their interest. The Holders of a
majority in aggregate principal amount of the Notes and other series of
Securities affected (treating the Notes and such other series as a single class)
then outstanding by notice to the Trustee may on behalf of the Holders of all of
the Notes waive any existing Default or Event of Default and its consequences
under the Indenture except a continuing Default or Event of

<Page>

Default in the payment of principal, interest or premium on the Notes. The
Company is required to deliver to the Trustee annually a statement regarding
compliance with the Indenture, and the Company is required upon becoming aware
of any Default or Event of Default, to deliver to the Trustee a statement
specifying such Default or Event of Default.

12.  TRUSTEE DEALINGS WITH THE COMPANY. The Trustee, in its individual or any
other capacity, may make loans to, accept deposits from, and perform services
for the Company or its Affiliates, and may otherwise deal with the Company or
its Affiliates, as if it were not the Trustee.

13.  NO RECOURSE AGAINST OTHERS. No director, officer, employee, incorporator or
stockholder of the Company shall have any liability for any obligations of the
Company under the Notes or the Indenture or for any claim based on, in respect
of, or by reason of, such obligations or their creation. Each Holder of Notes by
accepting a Note waives and releases all such liability. The waiver and release
are part of the consideration for the issuance of the Notes.

14.  AUTHENTICATION. This Note shall not be valid until authenticated by the
manual signature of the Trustee or an authenticating agent.

15.  ABBREVIATIONS. Customary abbreviations may be used in the name of a Holder
or an assignee, such as: TEN COM (= tenants in common), TEN ENT (= tenants by
the entireties), JT TEN (= joint tenants with right of survivorship and not as
tenants in common), CUST (= Custodian), and U/G/M/A (= Uniform Gifts to Minors
Act).

16.  CUSIP NUMBERS. Pursuant to a recommendation promulgated by the Committee on
Uniform Security Identification Procedures, the Company has caused CUSIP numbers
to be printed on the Notes and the Trustee may use CUSIP numbers in notices of
redemption as a convenience to Holders. No representation is made as to the
accuracy of such numbers either as printed on the Notes or as contained in any
notice of redemption and reliance may be placed only on the other identification
numbers placed thereon.

The Company will furnish to any Holder upon written request and without charge a
copy of the Indenture. Requests may be made to:

                                 THE SECURITIES

SECTION 2.01    FORM AND DATING.

     (a)  GENERAL. The Securities of each series shall be in substantially such
form as shall be established by or pursuant to a Board Resolution or in one or
more indentures supplemental hereto, in each case with such appropriate
insertions, omissions, substitutions and other variations as are required or
permitted by this Indenture, and may have such letters, numbers or other marks
of identification and such legends or endorsements placed thereon as may be
required to comply with the rules of any applicable securities exchange,
organizational document, governing instrument or law or as may, consistently
herewith, be determined by the officers executing such Securities as evidenced
by their execution of the Securities. If temporary Securities of any series are
issued as permitted by Section 2.12, the form thereof also shall be established
as provided in the preceding sentence. If the forms of Securities of any series
are established by, or by action taken pursuant to, a Board Resolution, a copy
of the Board Resolution, certified by the Secretary or an Assistant Secretary of
the Company to have been duly adopted by the Board of Directors and to be in
full force and effect on the date of the certificate, together with an
appropriate record of any such action taken pursuant thereto, including a copy
of the approved form of Securities shall be delivered to the Trustee at or prior
to the delivery of the Authentication Order contemplated by Section 2.04 for the
authentication and delivery of such Securities. The Trustee's certificate of
authentication shall be in substantially the following form:

within-mentioned Indenture.

     Bank One, N.A., as Trustee

     By:                                        Authorized Signatory
        ---------------------------------------

     (b)  GLOBAL SECURITIES. If Securities of or within a series are issuable in
whole or in part in global form, any such Security may provide that it shall
represent the aggregate or specified amount of outstanding Securities from time
to time endorsed thereon and may also provide that the aggregate amount of
outstanding Securities represented thereby may from time to time be reduced or
increased to reflect exchanges. Any endorsement of a Security in global form to
reflect the amount, or any increase or decrease in the amount, or changes in the
rights of Holders, of outstanding Securities represented thereby, shall be made
in such manner and by such Person or Persons as shall be specified therein or
upon the written order of the Company signed by an Officer to be delivered to
the Trustee pursuant to Section 2.04 or 2.12. Subject to the provisions of
Section 2.04, Section 2.12, if applicable, and Section 2.08, the Trustee shall
deliver and redeliver any Security in permanent global form in the manner and
upon instructions given by the Person or Persons specified therein or in the
applicable written order of the Company signed by an Officer. Any instructions
by the Company with respect to endorsement or delivery or redelivery of a
Security in global form shall be in writing. The provisions of the last
paragraph of Section 2.04 shall apply to any Security in global form if such
Security was never issued and sold by the Company and the Company delivers to
the Trustee the Security in global form together with a written instructions
with regard to the reduction in the principal amount of

                                        9

by the last paragraph of Section 2.04.

any, and interest on any Security in permanent global form shall be made to the
Holder thereof.

     (c)  All Securities of any one series shall be substantially identical
except as to denomination and except as may otherwise be provided (i) by a Board
Resolution, (ii) by action taken pursuant to a Board Resolution and set forth,
or determined in the manner provided, in the related Officers' Certificate or
(iii) in an indenture supplemental hereto. All Securities of any one series need
not be issued at the same time and, unless otherwise provided, a series may be
reopened, without the consent of the Holders, for issuances of additional
Securities of such series.

     (d)  If any of the terms of the Securities of any series are established by
action taken pursuant to a Board Resolution, a copy of such Board Resolution
shall be delivered to the Trustee at or prior to the delivery of the Officers'
Certificate setting forth, or providing the manner for determining, the terms of
the Securities of such series, and an appropriate record of any action taken
pursuant thereto in connection with the issuance of any Securities of such
series shall be delivered to the Trustee prior to the authentication and
delivery thereof.

SECTION 2.03    DENOMINATIONS.

     Unless otherwise provided as contemplated by Section 2.02, Securities of a
series denominated in Dollars shall be issuable in denominations of U.S. $1,000
and any integral multiple thereof. Securities denominated in a foreign currency
shall be issuable in such denominations as are established with respect to such
Securities in or pursuant to this Indenture.

SECTION 2.04    EXECUTION AND AUTHENTICATION.

     An Officer shall sign the Securities for the Company by manual or facsimile
signature.

     If an Officer whose signature is on a Security no longer holds that office
at the time a Security is authenticated, the Security shall nevertheless be
valid.

     A Security shall not be valid until authenticated by the manual signature
of the Trustee. The signature shall be conclusive evidence that the Security has
been authenticated under this Indenture.

     The Trustee shall, upon a written order of the Company signed by an Officer
(an "AUTHENTICATION ORDER"), together with an Officer's Certificate and an
Opinion of Counsel, authenticate Securities for original issue in the aggregate
principal amount stated in the

                                       13
<Page>

Authentication Order. The Officer's Certificate and Opinion of Counsel shall
each state that all conditions precedent provided for or relating to the
issuance of such Securities have been complied with.

     The Trustee may appoint an authenticating agent acceptable to the Company
to authenticate Securities. An authenticating agent may authenticate Securities
whenever the Trustee may do so. Each reference in this Indenture to
authentication by the Trustee includes authentication by such agent. An
authenticating agent has the same rights as an Agent to deal with Holders or an
Affiliate of the Company.

     Notwithstanding the foregoing, if any Security shall have been
authenticated and delivered hereunder but never issued and sold by the Company,
and the Company shall deliver such Security to the Trustee for cancellation as
provided in Section 2.13 together with a written statement stating that such
Security has never been issued and sold by the Company, for all purposes of this
Indenture such Security shall be deemed never to have been authenticated and
delivered hereunder and shall not be entitled to the benefits of this Indenture.

SECTION 2.05    REGISTRAR AND PAYING AGENT; APPOINTMENT OF DEPOSITARY.

     The Company shall maintain an office or agency where Securities may be
presented for registration of transfer or for exchange ("REGISTRAR") and an
office or agency where Securities may be presented for payment ("PAYING AGENT").
The Registrar shall keep a register of the Securities and of their transfer and
exchange. The Company may appoint one or more co-registrars and one or more
additional paying agents. The term "REGISTRAR" includes any co-registrar and the
term "PAYING AGENT" includes any additional paying agent. The Company may change
any Paying Agent or Registrar without notice to any Holder. The Company shall
promptly notify the Trustee in writing of the name and address of any Agent not
a party to this Indenture. If the Company fails to appoint or maintain another
entity as Registrar or Paying Agent, the Trustee shall act as such. The Company
or any of its Subsidiaries may act as Paying Agent or Registrar.

     The Company initially appoints The Depository Trust Company to act as
Depositary with respect to the Global Securities.

     The Company initially appoints the Trustee to act as the Registrar and
Paying Agent with respect to the Securities and to act as Custodian with respect
to the Global Securities.

SECTION 2.06    PAYING AGENT TO HOLD MONEY IN TRUST.

     The Company shall require each Paying Agent other than the Trustee to agree
in writing that the Paying Agent will hold in trust for the benefit of Holders
or the Trustee all money held by the Paying Agent for the payment of principal,
premium or interest (including Additional Interest) on the Securities or other
payment (including Additional Sums) in respect of the Securities or otherwise
held by it as Paying Agent, and will notify the Trustee of any default by the
Company in making any such payment when due. While any such default continues,
the Trustee may require a Paying Agent to pay all money held by it to the
Trustee. The Company at any time may require a Paying Agent to pay all money
held by it to the Trustee. Upon payment

                                       14
<Page>

over to the Trustee, the Paying Agent (if other than the Company or a
Subsidiary) shall have no further liability for the money. If the Company or a
Subsidiary acts as Paying Agent, it shall segregate and hold in a separate trust
fund for the benefit of the Holders all money held by it as Paying Agent. Upon
any bankruptcy or reorganization proceedings relating to the Company, the
Trustee shall serve as Paying Agent for the Securities.

SECTION 2.07    HOLDER LISTS.

     The Trustee shall preserve in as current a form as is reasonably
practicable the most recent list available to it of the names and addresses of
all Holders and shall otherwise comply with TIA ss.312(a). If the Trustee is not
the Registrar, the Company shall furnish to the Trustee at least seven Business
Days before each Interest Payment Date and at such other times as the Trustee
may request in writing, a list in such form and as of such date as the Trustee
may reasonably require of the names and addresses of the Holders of Securities,
and the Company shall otherwise comply with TIA ss.312(a).

SECTION 2.08    TRANSFER AND EXCHANGE.

     (a)  Upon surrender for registration of transfer of any certificated
Security of any series at the office or agency maintained pursuant to Section
4.02 in a place of payment for that series, the Company shall execute, and the
Trustee shall authenticate and deliver, in the name of the designated transferee
or transferees, one or more new certificated Securities of the same series, of
any authorized denominations and of a same aggregate principal amount and like
tenor and containing identical terms and provisions.

     (b)  At the option of the Holder, Securities of any series (except a
Security in global form) may be exchanged for other Securities of the same
series, of any authorized denominations, of a same aggregate principal amount
and like tenor and containing identical terms and provisions, upon surrender of
the Securities to be exchanged at such office or agency. Whenever any Securities
are so surrendered for exchange, the Company shall execute, and the Trustee
shall authenticate and deliver, the Securities which the Holder making the
exchange is entitled to receive.

     (c)  Notwithstanding any other provision of this Section, unless and until
it is exchanged in whole or in part for Securities in certificated form, a
Security in global form representing all or a portion of the Securities of a
series may not be transferred except as a whole by the Depositary for such
series to a nominee of such Depositary or by a nominee of such Depositary to
such Depositary or another nominee of such Depositary or by such Depositary or
any such nominee to a successor Depositary for such series or a nominee of such
successor Depositary.

     (d)  If at any time the Depositary for the Securities of a series notifies
the Company that it is unwilling or unable to continue as Depositary for the
Securities of such series or if at any time the Depositary for the Securities of
such series shall no longer be registered and in good standing as a clearing
agency under the Exchange Act, the Company shall appoint a successor Depositary
with respect to the Securities of such series. If a successor Depositary for the
Securities of such series is not appointed by the Company prior to the
resignation of the

Depositary and, in any event, within 90 days after the Company receives such
notice or becomes aware of such ineligibility, the Company's designation of the
Depositary pursuant to Section 2.02(b)(21) shall no longer be effective with
respect to the Securities of such series and the Company shall execute, and the
Trustee, upon receipt of an Authentication Order for the authentication and
delivery of certificated Securities of such series of like tenor, shall
authenticate and deliver, Securities of such series of like tenor in
certificated form, in authorized denominations and in an aggregate principal
amount equal to the principal amount of the Security or Securities of such
series of like tenor in global form in exchange for such Security or Securities
in global form.

     (e)  The Company may at any time in its sole discretion determine that all
(but not less than all) Securities of a series issued in global form shall no
longer be represented by such a Security or Securities in global form. In such
event the Company shall execute, and the Trustee, upon receipt of an
Authentication Order for the authentication and delivery of certificated
Securities of such series of like tenor, shall authenticate and deliver,
Securities of such series of like tenor in certificated form, in authorized
denominations and in an aggregate principal amount equal to the principal amount
of the Security or Securities of such series of like tenor in global form in
exchange for such Security or Securities in global form.

     (f)  If specified by the Company pursuant to Section 2.02 with respect to a
series of Securities, the Depositary for such series may surrender a Security in
global form of such series in exchange in whole or in part for Securities of
such series in certificated form on such terms as are acceptable to the Company
and such Depositary. Thereupon, the Company shall execute, and the Trustee shall
authenticate and deliver, without service charge,

          (i)   to each Person specified by such depositary a new certificated
     Security or Securities of the same series of like tenor, of any authorized
     denomination as requested by such Person in aggregate principal amount
     equal to and in exchange for such Person's beneficial interest in the
     Security in global form;

     and

          (ii)  to such Depositary a new Security in global form of like tenor
     in a denomination equal to the difference, if any, between the principal
     amount of the surrendered Security in global form and the aggregate
     principal amount of certificated Securities delivered to Holders thereof.

     (g)  Upon the exchange of a Security in global form for Securities in
certificated form, such Security in global form shall be canceled by the
Trustee. Securities in certificated form issued in exchange for a Security in
global form pursuant to this Section shall be registered in such names and in
such authorized denominations as the Depositary for such Security in global
form, pursuant to instructions from its direct or Indirect Participants or
otherwise, shall instruct the Trustee in writing. The Trustee shall deliver such
Securities to the Persons in whose names such Securities are so registered.

                                       16
<Page>

     (h)  Whenever any Securities are surrendered for exchange, the Company
shall execute, and the Trustee shall authenticate and deliver, the Securities
which the Holder making the exchange is entitled to receive.

     (i)  All Securities issued upon any registration of transfer or upon any
exchange of Securities shall be the valid obligations of the Company, evidencing
the same debt, and entitled to the same benefits under this Indenture, as the
Securities surrendered upon such registration of transfer or exchange.

     (j)  Every Security presented or surrendered for registration of transfer
or for exchange shall (if so required by the Company, the Registrar or the
Trustee) be duly endorsed, or be accompanied by a written instrument of transfer
in form satisfactory to the Company, the Registrar and the Trustee duly executed
by the Holder thereof or his attorney duly authorized in writing.

     (k)  No service charge shall be made for any registration of transfer or
for any exchange of Securities, but the Company may require payment of a sum
sufficient to cover any tax or other governmental charge that may be imposed in
connection with any registration or transfer or exchange of Securities, other
than exchanges pursuant to Section 2.12 or 3.06 not involving any transfer.

     (l)  The Company shall not be required (i) to issue, register the transfer
of, or exchange any Securities for a period beginning at the opening of business
15 days before any selection for redemption of Securities of like tenor and of
the series of which such Security is a part and ending at the close of business
on the earliest date on which the relevant notice of redemption is deemed to
have been given to all Holders of Securities of like tenor and of such series to
be redeemed; or (ii) to 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.

     (m)  The foregoing provisions relating to registration, transfer and
exchange may be modified, supplemented or superseded with respect to any series
of Securities by a Board Resolution or in one or more indentures supplemental
hereto.

     (n)  The following legend shall appear on the face of all Global Securities
unless specifically stated otherwise in the applicable provision of this
Indenture:

     "THIS GLOBAL SECURITY IS HELD BY THE DEPOSITARY (AS DEFINED IN THE
INDENTURE GOVERNING THIS SECURITY) OR ITS NOMINEE IN CUSTODY FOR THE BENEFIT OF
THE BENEFICIAL OWNERS HEREOF, AND, UNLESS AND UNTIL IT IS EXCHANGED FOR
SECURITIES IN DEFINITIVE FORM IN ACCORDANCE WITH THE INDENTURE, (I) IS NOT
TRANSFERABLE EXCEPT AS A WHOLE BY THE DEPOSITARY TO A NOMINEE OF THE DEPOSITARY,
OR BY A NOMINEE OF THE DEPOSITARY TO THE DEPOSITARY OR ANOTHER NOMINEE OF THE
DEPOSITARY, OR BY THE DEPOSITARY OR ANY SUCH NOMINEE TO A SUCCESSOR DEPOSITARY
OR SUCCESSOR NOMINEE, AND (II) MAY NOT BE EXCHANGED OR CANCELLED EXCEPT IN THE
LIMITED CIRCUMSTANCES DESCRIBED IN THE INDENTURE."

                                       17
<Page>

     (o)  At such time as all beneficial interests in a particular Global
Security have been exchanged for definitive Securities or a particular Global
Security has been redeemed, repurchased or canceled in whole and not in part,
each such Global Security shall be returned to or retained and canceled by the
Trustee in accordance with Section 2.13 hereof. At any time prior to such
cancellation, if any beneficial interest in a Global Security is exchanged for
or transferred to a Person who will take delivery thereof in the form of a
beneficial interest in another Global Security or for definitive Securities, the
principal amount of Securities represented by such Global Security shall be
reduced accordingly and an endorsement shall be made on such Global Security by
the Trustee or by the Depositary at the direction of the Trustee to reflect such
reduction; and if the beneficial interest is being exchanged for or transferred
to a Person who will take delivery thereof in the form of a beneficial interest
in another Global Security, such other Global Security shall be increased
accordingly and an endorsement shall be made on such Global Security by the
Trustee or by the Depositary at the direction of the Trustee to reflect such
increase.

     (p)  Prior to due presentment for the registration of a transfer of any
Security, the Trustee, any Agent and 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 interest on such
Securities and for all other purposes, and neither the Trustee, any Agent nor
the Company shall be affected by notice to the contrary. Notwithstanding the
foregoing, with respect to any Global Security, nothing herein shall prevent the
Company, the Trustee or any agent of the Company or the Trustee from giving
effect to any written certification, proxy or other authorization furnished by
any Depositary, as a Holder, with respect to such Global Security or impair, as
between such Depositary and owners of beneficial interests in such Global
Security, the operation of customary practices governing the exercise of the
rights of such Depositary (or its nominee) as Holder of such Global Security.

SECTION 2.09    REPLACEMENT SECURITIES.

     If any mutilated Security is surrendered to the Trustee or the Company and
the Trustee receives evidence to its satisfaction of the destruction, loss or
theft of any Security, the Company shall issue and the Trustee, upon receipt of
an Authentication Order, shall authenticate a replacement Security if the
Trustee's requirements are met. If required by the Trustee or the Company, 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
and any authenticating agent from any loss that any of them may suffer if a
Security is replaced. The Company may charge for its expenses in replacing a
Security.

     Every replacement Security is an additional 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.

                                       18
<Page>

SECTION 2.10    OUTSTANDING SECURITIES.

     The Securities outstanding at any time are all the Securities authenticated
by the Trustee except for those canceled by it, those delivered to it for
cancellation, those reductions in the interest in a Global Security effected by
the Trustee in accordance with the provisions hereof, and those described in
this Section as not outstanding. Except as set forth in Section 2.11 hereof, a
Security does not cease to be outstanding because the Company or an Affiliate of
the Company holds the Security.

     If a Security is replaced pursuant to Section 2.09 hereof, it ceases to be
outstanding unless the Trustee receives proof satisfactory to it that the
replaced Security is held by a "protected purchaser" (within the meaning of
Article 8 of the Uniform Commercial Code) or a Person with comparable status
under other applicable law.

     If the principal amount of any Security is considered paid under Section
4.01 hereof, it ceases to be outstanding and interest on it ceases to accrue.

     If the Paying Agent (other than the Company, a Subsidiary or an Affiliate
of any thereof) holds, on a redemption date or maturity date, money sufficient
to pay Securities payable on that date, then on and after that date such
Securities shall be deemed to be no longer outstanding and shall cease to accrue
interest.

SECTION 2.11    TREASURY SECURITIES.

     In determining whether the Holders of the required principal amount of
Securities have concurred in any direction, waiver or consent, Securities owned
by the Company, or by any Person directly or indirectly controlling or
controlled by or under direct or indirect common control with the Company, shall
be considered as though not outstanding, except that for the purposes of
determining whether the Trustee shall be protected in relying on any such
direction, waiver or consent, only Securities that the Trustee knows are so
owned shall be so disregarded.

SECTION 2.12    TEMPORARY SECURITIES.

     Until certificates representing Securities are ready for delivery, the
Company may prepare and the Trustee, upon receipt of an Authentication Order,
shall authenticate temporary Securities. Temporary Securities shall be
substantially in the form of certificated Securities but may have variations
that the Company considers appropriate for temporary Securities and as shall be
reasonably acceptable to the Trustee. Without unreasonable delay, the Company
shall prepare and the Trustee shall authenticate definitive Securities in
exchange for temporary Securities.

     Holders of temporary Securities shall be entitled to all of the benefits of
this Indenture.

SECTION 2.13    CANCELLATION.

     The Company at any time may deliver Securities to the Trustee for
cancellation. The Registrar and Paying Agent shall forward to the Trustee any
Securities surrendered to them for registration of transfer, exchange or
payment. The Trustee and no one else shall cancel all

                                       19
<Page>

Securities surrendered for registration of transfer, exchange, payment,
replacement or cancellation and shall destroy canceled Securities (subject to
the record retention requirement of the Exchange Act). Certification of the
destruction of all canceled Securities shall be delivered to the Company. The
Company may not issue new Securities to replace Securities that it has paid or
that have been delivered to the Trustee for cancellation.

SECTION 2.14    DEFAULTED INTEREST.

     If the Company defaults in a payment of interest on the Securities, it
shall pay the defaulted interest in any lawful manner plus, to the extent
lawful, interest payable on the defaulted interest ("Additional Interest"), to
the Persons who are Holders on a subsequent special record date, in each case at
the rate provided in the Securities. The Company shall notify the Trustee in
writing of the amount of defaulted interest proposed to be paid on each Security
and the date of the proposed payment. The Company shall fix or cause to be fixed
each such special record date and payment date, PROVIDED that no such special
record date shall be less than 10 days prior to the related payment date for
such defaulted interest. At least 15 days before the special record date, the
Company (or, upon the written request of the Company, the Trustee in the name
and at the expense of the Company) shall mail or cause to be mailed to Holders a
notice that states the special record date, the related payment date and the
amount of such interest to be paid. Subject to the foregoing provisions of this
Section, each Security delivered under this Indenture upon registration of
transfer of or in exchange for or in lieu of any other Security shall carry the
rights to interest accrued and unpaid, and to accrue, which were carried by such
other Security.

                                    ARTICLE 3
                            REDEMPTION AND PREPAYMENT

SECTION 3.01    APPLICABILITY OF ARTICLE.

     The provisions of this Article shall be applicable to the Securities of any
series which are redeemable before their maturity or to any sinking fund for the
retirement of Securities of a series except as otherwise specified as
contemplated by Section 2.02 for Securities of such series.

SECTION 3.02    SELECTION OF SECURITIES TO BE REDEEMED.

     If less than all of the Securities of any series are to be redeemed at any
time, the Trustee shall select the Securities of such series to be redeemed
among the Holders of the Securities of such series in compliance with the
requirements of the principal national securities exchange, if any, on which the
Securities of such series are listed or, if the Securities of such series are
not so listed, to be redeemed among the Holders of Securities of such series on
a PRO RATA basis, by lot or by such method as the Trustee deems fair and
appropriate; PROVIDED that no Securities of $1,000 or less shall be redeemed in
part. In the event of partial redemption by lot, the particular Securities of
such series to be redeemed shall be selected, unless otherwise provided herein,
not less than 30 days nor more than 60 days prior to the redemption date by the
Trustee from the outstanding Securities of the series not previously called for
redemption.

                                       20
<Page>

     The Trustee shall promptly notify the Company in writing of the Securities
selected for redemption and, in the case of any Security selected for partial
redemption, the principal amount thereof to be redeemed. Securities and portions
of Securities selected shall be in amounts of $1,000 or whole multiples of
$1,000; except that if all of the Securities of a series of a Holder are to be
redeemed, the entire outstanding amount of Securities of such series held by
such Holder, even if not a multiple of $1,000, shall be redeemed. A new Security
of the same series in principal amount equal to the unredeemed portion thereof
will be issued in the name of the Holder thereof upon cancellation of the
original Security. Securities called for redemption shall become due on the
redemption date. On and after the redemption date, interest will cease to accrue
on the Securities or portions of them called for redemption. Except as provided
in this Section 3.02, provisions of this Indenture that apply to Securities
called for redemption shall also apply to portions of Securities called for
redemption.

SECTION 3.03    NOTICE OF REDEMPTION.

     At least 30 days but not more than 60 days before a redemption date, the
Company shall mail or cause to be mailed, by first class mail, a notice of
redemption to each Holder whose Securities are to be redeemed at its registered
address.

     The notice shall identify the Securities to be redeemed, including the
series thereof, and shall state:

     (a)  the redemption date;

     (b)  the redemption price;

     (c)  the name and address of the Paying Agent;

     (d)  that Securities called for redemption must be surrendered to the
Paying Agent to collect the redemption price;

     (e)  that, unless the Company defaults in making such redemption payment,
interest on Securities called for redemption will cease to accrue on and after
the redemption date;

     (f)  that any Security being redeemed in part, the portion of the principal
amount of such Security to be redeemed and that, after the redemption date upon
surrender of such Security, a new Security or Securities of the same series in
principal amount equal to the unredeemed portion shall be issued upon
cancellation of the original;

     (g)  the paragraph of the Securities and/or Section of this Indenture
pursuant to which the Securities called for redemption are being redeemed; and

     (h)  that no representation is made as to the correctness or accuracy of
the CUSIP number, if any, listed in such notice or printed on the Securities.

     At the Company's request, the Trustee shall give the notice of redemption
in the Company's name and at the Company's expense; PROVIDED, HOWEVER, that the
Company shall have delivered to the Trustee, at least 30 days prior to the
redemption date, an Officers'

                                       21
<Page>

Certificate requesting that the Trustee give such notice and setting forth the
information to be stated in such notice as provided in the preceding paragraph.

SECTION 3.04    EFFECT OF NOTICE OF REDEMPTION.

     Once notice of redemption is mailed in accordance with Section 3.03 hereof,
Securities called for redemption become irrevocably due and payable on the
redemption date at the redemption price. A notice of redemption may not be
conditional.

SECTION 3.05    DEPOSIT OF REDEMPTION OR PURCHASE PRICE.

     One Business Day prior to 10:00 a.m., Eastern Time, on any redemption date,
the Company shall deposit with the Trustee or with the Paying Agent money in
immediately available funds sufficient to pay the redemption or purchase price
of and accrued interest, if any, on all Securities to be redeemed or purchased
on that date. The Trustee or the Paying Agent shall promptly return to the
Company any money deposited with the Trustee or the Paying Agent by the Company
in excess of the amounts necessary to pay the redemption or purchase price of,
and accrued interest on, all Securities to be redeemed or purchased.

SECTION 3.06    SECURITIES REDEEMED OR PURCHASED IN PART.

     Upon surrender of a Security that is redeemed or purchased in part, the
Company shall issue and, upon the Company's written request, the Trustee shall
authenticate for the Holder at the expense of the Company a new Security of the
same series equal in principal amount to the unredeemed or unpurchased portion
of the Security surrendered.

SECTION 3.07    MANDATORY REDEMPTION; SINKING FUND.

     The Company shall not be required to make mandatory redemption or sinking
fund payments with respect to the Securities, unless otherwise specified in the
terms of a particular series of Securities. If a mandatory or optional sinking
fund is specified in the terms of a particular series of Securities, the
following provisions will apply thereto (unless otherwise specified):

     The minimum amount of any sinking fund payment provided for by the terms of
Securities of any series is herein referred to as a "mandatory sinking fund
payment", and any payment in excess of such minimum amount provided for by the
terms of Securities of any series is herein referred to as an "optional sinking
fund payment." The last date on which any such payment may be made is herein
referred to as a "sinking fund payment date."

     In lieu of making all or any part of any mandatory sinking fund payment
with respect to any Securities of a series in cash, the Company may at its
option (a) deliver to the Trustee Securities of that series theretofore
purchased by the Company and (b) may apply as a credit Securities of that series
which have been redeemed either at the election of the Company pursuant to the
terms of such Securities or through the application of optional sinking fund
payments pursuant to the next succeeding paragraph, in each case in satisfaction
of all or any part of any mandatory sinking fund payment, provided that such
Securities have not been previously so credited. Each such Security so delivered
or applied as a credit shall be credited at

                                       22
<Page>

the sinking fund redemption price for such Securities and the amount of any
mandatory sinking fund shall be reduced accordingly. If the Company intends so
to deliver or credit such Securities with respect to any mandatory sinking fund
payment it shall deliver to the Trustee at least 30 days prior to the next
succeeding sinking fund payment date for such series (a) a certificate signed by
any Officer specifying the portion of such sinking fund payment, if any, to be
satisfied by payment of cash and the portion of such sinking fund payment, if
any, which is to be satisfied by delivering and crediting such Securities and
(b) any Securities to be so delivered. All Securities so delivered to the
Trustee shall be cancelled by the Trustee and no Securities shall be
authenticated in lieu thereof. If the Company fails to deliver such certificate
and Securities at or before the time provided above, the Company shall not be
permitted to satisfy any portion of such mandatory sinking fund payment by
delivery or credit of Securities.

     At its option the Company may pay into the sinking fund for the retirement
of Securities of any particular series, on or before each sinking fund payment
date for such series, any additional sum in cash as specified by the terms of
such series of Securities. If the Company intends to exercise its right to make
any such optional sinking fund payment, it shall deliver to the Trustee at least
30 days prior to the next succeeding sinking fund payment date for such series
of Securities a certificate signed by any Officer stating that the Company
intends to exercise such optional right and specifying the amount which the
Company intends to pay on such sinking fund payment date. If the Company fails
to deliver such certificate at or before the time provided above, the Company
shall not be permitted to make any optional sinking fund payment with respect to
such sinking fund payment date. To the extent that such right is not exercised
in any year it shall not be cumulative or carried forward to any subsequent
year.

     If the sinking fund payment or payments (mandatory or optional) made in
cash plus any unused balance of any preceding sinking fund payments made in cash
shall exceed $50,000 (or a lesser sum if the Company shall so request) with
respect to the Securities of any particular series, it shall be applied by the
Trustee or one or more Paying Agents on the next succeeding sinking fund payment
date to the redemption of Securities of such series at the sinking fund
redemption price together with accrued interest to the date fixed for
redemption. The Trustee shall select, in the manner provided in Section 3.02,
for redemption on such sinking fund payment date a sufficient principal amount
of Securities of such series to exhaust said cash, as nearly as may be, and the
Trustee shall, at the expense and in the name of the Company, thereupon cause
notice of redemption of Securities of such series to be given in substantially
the manner and with the effect provided in Sections 3.02 and 3.03 for the
redemption of Securities of that series in part at the option of the Company,
except that the notice of redemption shall also state that the Securities of
such series are being redeemed for the sinking fund. Any sinking fund moneys not
so applied or allocated by the Trustee or any Paying Agent to the redemption of
Securities of that series shall be added to the next cash sinking fund payment
received by the Trustee or the Paying Agent and, together with such payment,
shall be applied in accordance with the provisions of this Section 3.07. Any and
all sinking fund moneys held by the Trustee or any Paying Agent on the maturity
date of the Securities of any particular series, and not held for the payment or
redemption of particular Securities of such series, shall be applied by the
Trustee or such Paying Agent, together with other moneys, if necessary, to be
deposited sufficient for the purpose, to the payment of the principal of the
Securities of that series at maturity. On or before each sinking fund payment
date, the Company shall pay to the Trustee or to one or more Paying Agents in
cash a sum equal to all interest accrued to the date fixed for redemption on
Securities to be

                                       23
<Page>

redeemed on the next following sinking fund payment date pursuant to this
Section. Neither the Trustee nor any Paying Agent shall redeem any Securities of
a series with sinking fund moneys, and the Trustee shall not mail any notice of
redemption of Securities for such series by operation of the sinking fund,
during the continuance of a default in payment of interest on such Securities or
of any Event of Default (other than an Event of Default occurring as a
consequence of this paragraph), except that if the notice of redemption of any
Securities shall theretofore have been mailed in accordance with the provisions
hereof, the Trustee or any paying agent shall redeem such Securities if cash
sufficient for that purpose shall be deposited with the Trustee or such paying
agent for that purpose in accordance with the terms of this Article 3. Except as
aforesaid, any moneys in the sinking fund for such series at the time when any
such default or Event of Default shall occur and any moneys thereafter paid into
the sinking fund shall, during the continuance of such default or Event of
Default, be held as security for the payment of all such Securities; provided,
however, that in case such Event of Default or default shall have been cured or
waived as provided herein, such moneys shall thereafter be applied on the next
succeeding sinking fund payment date on which such moneys may be applied
pursuant to the provisions of this Section 3.07.

                                    ARTICLE 4
                                    COVENANTS

SECTION 4.01    PAYMENT OF SECURITIES.

     The Company shall pay or cause to be paid the principal of, premium, if
any, and interest on the Securities on the dates and in the manner provided in
the Securities. Principal, premium, if any, and interest shall be considered
paid on the date due if the Paying Agent, if other than the Company or a
Subsidiary thereof, holds as of 10:00 a.m., Eastern Time, on the due date money
deposited by the Company in immediately available funds and designated for and
sufficient to pay all principal, premium, if any, and interest then due.

SECTION 4.02    MAINTENANCE OF OFFICE OR AGENCY.

     The Company shall maintain in the Borough of Manhattan, the City of New
York, an office or agency (which may be an office of the Trustee or an affiliate
of the Trustee, Registrar or co-Registrar) where Securities may be surrendered
for registration of transfer or for exchange and where notices and demands to or
upon the Company in respect of the Securities and this Indenture may be served.
The Company shall give prompt written notice to the Trustee of the location, and
any change in the location, of such office or agency. If at any time the Company
shall fail to maintain any such required office or agency or shall fail to
furnish the Trustee with the address thereof, such presentations, surrenders,
notices and demands may be made or served at the Trustee's principal agency in
the Borough of Manhattan, the City of New York, which currently is located at
________________________________________.

     The Company may also from time to time designate one or more other offices
or agencies where the Securities may be presented or surrendered for any or all
such purposes and may from time to time rescind such designations; PROVIDED,
HOWEVER, that no such designation or rescission shall in any manner relieve the
Company of its obligation to maintain an office or

                                       24
<Page>

agency in the Borough of Manhattan, the City of New York for such purposes. The
Company shall give prompt written notice to the Trustee of any such designation
or rescission and of any change in the location of any such other office or
agency.

SECTION 4.03    REPORTS.

     (a)  Whether or not the Company is subject to Section 13 or 15(d) of the
Exchange Act, the Company covenants and agrees to file with the Trustee, and to
provide by mail to each Holder, within 15 days after the Company is or would be
required to file the same with the SEC, copies of the annual reports, quarterly
reports and the information, documents and other reports which the Company is or
would be required to file with the SEC pursuant to Section 13 or Section 15(d)
of the Exchange Act.

     (b)  The Company covenants and agrees to file with the Trustee and the SEC,
in accordance with the rules and regulations prescribed from time to time by the
SEC, such additional information, documents and reports with respect to
compliance by the Company with the conditions and covenants provided for in this
Indenture as may be required from time to time by such rules and regulations.

     (c)  The Company covenants and agrees to furnish to the Trustee within 120
days of the end of each fiscal year, the compliance certificate required by
Section 314(a)(4) of the Trust Indenture Act.

     (d)  Delivery of such reports, information and documents to the Trustee is
for informational purposes only and the Trustee's receipt of such shall not
constitute constructive notice of any information contained therein or
determinable from information contained therein, including the Company's
compliance with any of its covenants hereunder (as to which the Trustee is
entitled to rely exclusively on Officers' Certificates).

SECTION 4.04    COMPLIANCE CERTIFICATE.

     (a)  The Company shall deliver to the Trustee, within 90 days after the end
of each fiscal year, an Officers' Certificate stating that a review of the
activities of the Company and its Subsidiaries during the preceding fiscal year
has been made under the supervision of the signing Officers with a view to
determining whether the Company has kept, observed, performed and fulfilled its
obligations under this Indenture, and further stating, as to each such Officer
signing such certificate, that to the best of his or her knowledge the Company
has kept, observed, performed and fulfilled each and every covenant contained in
this Indenture and is not in default in the performance or observance of any of
the terms, provisions and conditions of this Indenture (or, if a Default, Event
of Default or other instance of non-compliance with any of the terms of this
Indenture shall have occurred, describing all such Defaults, Events of Default
or instances of non-compliance of which he or she may have knowledge and what
action the Company is taking or proposes to take with respect thereto) and that
to the best of his or her knowledge no event has occurred and remains in
existence by reason of which payments on account of the principal of, premium,
if any, or interest on the Securities is prohibited or if such event has
occurred, a description of the event and what action the Company is taking or
proposes to take with respect thereto.

                                       25

     (b)  The Company shall, so long as any of the Securities are outstanding,
deliver to the Trustee, forthwith upon any Officer of the Company becoming aware
of any Default or Event of Default, an Officers' Certificate specifying such
Default or Event of Default and what action the Company is taking or proposes to
take with respect thereto.

     (c)  The Company shall file with the Trustee and the SEC, in accordance
with the rules and regulations prescribed from time to time by the SEC, such
additional information, documents and reports with respect to compliance by the
Company with the conditions and covenants provided for in this Indenture, as may
be required from time to time by such rules and regulations.

SECTION 4.05    CONTINUED EXISTENCE.

     Subject to Article 5 hereof, the Company shall do or cause to be done all
things necessary to preserve and keep in full force and effect (i) its corporate
existence, and the corporate, partnership or other existence of each of its
Significant Subsidiaries, in accordance with the respective organizational
documents (as the same may be amended from time to time) of the Company or any
such Significant Subsidiary and (ii) the rights (charter and statutory),
licenses and franchises of the Company and any of its Significant Subsidiaries;
PROVIDED, HOWEVER, that the Company shall not be required to preserve any such
right, license or franchise, or the corporate, partnership or other existence of
any of its Significant Subsidiaries, if the Board of Directors shall determine
that the preservation thereof is no longer desirable in the conduct of the
business of the Company and its Significant Subsidiaries, taken as a whole, and
that the loss thereof is not adverse in any material respect to the Holders of
the Securities.

SECTION 4.06    STAY, EXTENSION AND USURY LAWS.

     The Company covenants (to the extent that it may lawfully do so) that it
shall not at any time insist upon, plead, or in any manner whatsoever claim or
take the benefit or advantage of, any stay, extension or usury law wherever
enacted, now or at any time hereafter in force, that 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 shall not, by resort to any such law, hinder, delay
or impede the execution of any power herein granted to the Trustee, but shall
suffer and permit the execution of every such power as though no such law has
been enacted.

SECTION 4.07    LIMITATION ON DIVIDENDS; TRANSACTIONS WITH AFFILIATES.

     When Securities of any series are issued to a Trust or a trustee of a Trust
in connection with the issuance of Trust Securities, and (a) there shall have
occurred an Event of Default with respect to such series, or (b) the Company
shall be in default with respect to its payment of any obligations under the
Trust Preferred Securities Guarantee or Trust Common Securities Guarantee
relating to such Trust, or (c) the Company shall have given notice of its
election to exercise its right to extend the interest payment provision pursuant
to Section 11.02, then (i) the Company shall not declare or pay any dividend on,
make any distribution with respect to, or redeem, purchase, acquire or make a
liquidation payment with respect to, any of its capital stock

                                       26
<Page>

(other than (A) dividends or distributions in shares of, or options, warrants or
rights to subscribe for or purchase shares of, common stock of the Company, (B)
any declaration of a dividend in connection with a stockholders' rights plan of
the Company, or the issuance of stock under such a plan, or the redemption or
repurchase of any rights pursuant thereto, (C) purchases or acquisitions of
shares of Common Stock in connection with the satisfaction by the Company of its
obligations under any benefit plans for the Company's directors, officers,
employees or producers or dividend reinvestment plans or any other contractual
obligation of the Company (other than a contractual obligation ranking PARI
PASSU with or junior to the Securities), (D) as a result of a reclassification
of the Company's capital stock or the exchange or conversion of one class or
series of the Company's capital stock for another class or series of the
Company's capital stock, or (E) the purchase of fractional interests in shares
of the Company's capital stock pursuant to the conversion or exchange provisions
of such Company capital stock or the security being converted or exchanged),
(ii) the Company shall not make any payment of interest, principal or premium,
if any, on or repay, repurchase or redeem any debt securities issued by the
Company that rank PARI PASSU with or junior to the Securities; and (iii) the
Company shall not make any guarantee payments with respect to the foregoing
(other than pursuant to the related Trust Preferred Securities Guarantee).

SECTION 4.08    CERTAIN ADDITIONAL COVENANTS.

     For so long as Trust Securities remain outstanding, the Company will (i)
maintain 100%, direct or indirect, ownership of the Trust Common Securities of
each Trust issuing Trust Preferred Securities; PROVIDED, HOWEVER, that any
permitted successor of the Company under this Indenture may succeed to the
Company's ownership of such Trust Common Securities, (ii) use its reasonable
efforts to cause such Trust (a) to remain a statutory trust, except in
connection with a distribution of Securities to the holders of Trust Securities
in liquidation of such Trust, the redemption of all of the Trust Securities of
such Trust or certain mergers, consolidations or amalgamations, each as
permitted by the applicable Trust Agreement, and (b) to otherwise continue not
to be treated as an association taxable as a corporation for United States
Federal income tax purposes and (iii) use its reasonable efforts to cause each
holder of Trust Securities to be treated as owning an individual beneficial
interest in the Securities.

SECTION 4.09    INTEREST.

     If, at any time while a Trust is the Holder of any Securities, such Trust
is required to pay any taxes, duties, assessments or governmental charges of
whatever nature (other than withholding taxes) imposed by the United States, or
any other taxing authority, then, in any such case, the Company will pay as
additional interest on the Securities held by such Trust, such additional
amounts ("Additional Sums") as shall be required so that the net amounts
received and retained by such Trust after paying such taxes, duties, assessments
or other governmental charges will be equal to the amounts such Trust would have
received had no such taxes, duties, assessments or other governmental charges
been imposed.

SECTION 5.01    MERGER, CONSOLIDATION, OR SALE OF ASSETS.

     The Company may consolidate or merge with or into, convert itself into, or
sell, assign, transfer, lease, convey or otherwise dispose of (including any
such disposition that might be deemed to occur as a result of the conversion of
the Company into another form of organization) all or substantially all of its
properties or assets in one or more related transactions, to another Person
(other than an individual, a government or an agency or political subdivision of
a government), but only if (a) either (i) the Company is the surviving
corporation or (ii) the Person formed by or surviving any such consolidation,
merger or conversion (if other than the Company) or to which such sale,
assignment, transfer, lease, conveyance or other disposition shall have been
made is a Person organized or existing under the laws of the United States, any
state thereof or the District of Columbia; (b) the Person formed by or surviving
any such consolidation, merger or conversion (if other than the Company) or the
Person to which such sale, assignment, transfer, lease, conveyance or other
disposition shall have been made assumes all the obligations of the Company
under the Securities and this Indenture pursuant to a supplemental indenture in
a form reasonably satisfactory to the Trustee; and (c) immediately after such
transaction no Default or Event of Default exists. If the Company requests the
Trustee to enter into any supplemental indenture, or to take any other action,
as a result of such consolidation, merger, sale, assignment, transfer, lease,
conveyance or other disposition, the Company will also furnish to the Trustee an
Officer's Certificate and an Opinion of Counsel, each to the effect that the
conditions precedent set forth in this Section 5.01 have been complied with.

SECTION 5.02    SUCCESSOR PERSON SUBSTITUTED.

     Upon any consolidation, merger or conversion, or any sale, assignment,
transfer, lease, conveyance or other disposition of all or substantially all of
the assets of the Company in accordance with Section 5.01 hereof, the successor
Person formed by such consolidation or into or with which the Company is merged
or converted or to which such sale, assignment, transfer, lease, conveyance or
other disposition is made shall succeed to, and be substituted for (so that from
and after the date of such consolidation, merger, conversion, sale, lease,
conveyance or other disposition, the provisions of this Indenture referring to
the "Company" shall refer instead to the successor Person and not to the
Company), and may exercise every right and power of, the Company under this
Indenture with the same effect as if such successor Person had been named as the
Company herein; PROVIDED, HOWEVER, that the predecessor Company shall not be
relieved from the obligation to pay the principal of and interest on the
Securities except in the case of a sale of all of the Company's assets that
meets the requirements of Section 5.01 hereof.

                              DEFAULTS AND REMEDIES

SECTION 6.01    EVENTS OF DEFAULT.

     An "Event of Default," with respect to Securities of any series shall have
occurred if:

     (a)  the Company defaults in the payment when due of interest on, with
respect to, any Security of that series and such default continues for a period
of 30 days;

     (b)  the Company defaults in the payment when due of principal of or
premium, if any, on, or sinking fund payment with respect to, any Security of
that series when the same becomes due and payable at maturity, upon redemption
or otherwise;

     (c)  the Company fails to comply with any of the provisions of section 5.01
hereof;

     (d)  the Company fails to observe or perform any other covenant,
representation, warranty or other agreement in this Indenture, with respect to
any Security of that series for 60 days after notice to comply;

     (e)  the Company, pursuant to or within the meaning of any Bankruptcy Law:

          (i)   commences a voluntary case,

          (ii)  consents to the entry of an order for relief against it in an
     involuntary case,

          (iii) consents to the appointment of a custodian of it or for all or
     substantially all of its property,

          (iv)  makes a general assignment for the benefit of its creditors,
     or

          (v)   generally is not paying its debts as they become due;

     (f)  a court of competent jurisdiction enters an order or decree under any
Bankruptcy Law that:

          (i)   is for relief against the Company in an involuntary case;

          (ii)  appoints a custodian of the Company for all or substantially all
     of the property of the Company; or

          (iii) orders the liquidation of the Company;

     and the order or decree remains unstayed and in effect for 60 consecutive
     days;

     (g)  the Trust holding such Securities shall have voluntarily or
involuntarily dissolved, wound-up its business or otherwise terminated its
existence, except in connection with (i) the distribution of Securities of such
series to holders of such Trust Securities in liquidation of their interests in
such Trust, (ii) the redemption of all of the outstanding Trust Securities of
such Trust

                                       29
<Page>

or (iii) certain mergers, consolidations or amalgamations, each as permitted by
the Trust Agreement of such Trust; or (h) any other event provided with respect
to Securities of that series in the terms thereof.

     The term "CUSTODIAN" as used in this Article 6 means any receiver, trustee,
assignee, liquidator or similar official under any Bankruptcy Law.

     A Default under clause (d) with respect to the Securities of any series is
not an Event of Default until the Trustee notifies the Company, or the Holders
of at least 25% in principal amount of the then outstanding Securities of such
series and of all Pari Passu Series with respect to which such Default shall
have occurred (treating such series and all Pari Passu Series as a single class)
notify the Company and the Trustee, of the Default and the Company does not cure
the Default within 60 days after receipt of the notice. The notice must specify
the Default, demand that it be remedied and state that the notice is a "NOTICE
OF DEFAULT." The holders of Trust Preferred Securities then outstanding of
Trusts holding Securities of a series with respect to which a Default shall have
occurred and Securities of all Pari Passu Series with respect to which such
Default shall have occurred may participate in giving the Notice of Default,
substituting for such purpose the liquidation preference of the related Trust
Preferred Securities for an equivalent principal amount of Securities (on a
dollar-for-dollar basis) as to which such holders so participate.

SECTION 6.02    ACCELERATION.

     If any Event of Default with respect to any series of Securities (other
than an Event of Default specified in clause (e) or (f) of Section 6.01 hereof)
occurs and is continuing, the Trustee or the Holders of at least 25% in
principal amount of the then outstanding Securities of such series and of all
Pari Passu Series with respect to which such Event of Default shall have
occurred (treating such series and all Pari Passu Series as a single class) may
declare all the Securities of all such series to be due and payable immediately.
The holders of Trust Preferred Securities then outstanding of Trusts holding
Securities of a series with respect to which an Event of Default shall have
occurred and be continuing and Securities of all Pari Passu Series with respect
to which such Event of Default shall have occurred and be continuing may
participate in the declaration, substituting for such purpose the liquidation
preference of the related Trust Preferred Securities for an equivalent principal
amount of Securities (on a dollar-for-dollar basis) as to which such holders so
participate. Upon any such declaration, the principal of, premium, if any, and
accrued and unpaid interest with respect to the Securities of all such series
shall become due and payable immediately. Notwithstanding the foregoing, if an
Event of Default specified in clause (e) or (f) of Section 6.01 hereof occurs
with respect to the Company, all outstanding Securities of all series shall be
due and payable immediately without further action or notice, PROVIDED that the
payment of principal and interest on such Securities shall remain subordinated
to the extent provided in Article 10.

                                       30
<Page>

SECTION 6.03    OTHER REMEDIES.

     If an Event of Default occurs and is continuing, the Trustee may pursue any
available remedy to collect the payment of principal, premium, if any, and
interest on the Securities or to enforce the performance of any provision of the
Securities or this Indenture.

     The Trustee may maintain a proceeding even if it does not possess any of
the Securities or does not produce any of them in the proceeding. A delay or
omission by the Trustee or any Holder of a Security in exercising any right or
remedy accruing upon an Event of Default shall not impair the right or remedy or
constitute a waiver of or acquiescence in the Event of Default. All remedies are
cumulative to the extent permitted by law.

SECTION 6.04    WAIVER OF PAST DEFAULTS; RESCISSION OF ACCELERATION.

     Holders of a majority in aggregate principal amount of the then outstanding
Securities of a series and of all Pari Passu Series affected (treating all such
series as a single class) may, by notice to the Trustee on behalf of the Holders
of all of the Securities of all such series, waive an existing Default or Event
of Default and its consequences hereunder (including in connection with an offer
to purchase or exchange), except a continuing Default or Event of Default in the
payment of the principal of, premium, if any, interest on, or any sinking fund
payment with respect to, the Securities of such series, and except a continuing
Default or Event of Default under any provision of this Indenture that, under
Section 9.02, cannot be modified or waived without the consent of a greater
number of Holders or of each Holder affected. Upon any such waiver, such Default
or Event of Default shall be deemed to have been cured for every purpose of this
Indenture; but no such waiver shall extend to any subsequent or other Default or
Event of Default or impair any right consequent thereon. The Holders of a
majority in aggregate principal amount of the then outstanding Securities of a
series and of all Pari Passu Series affected may also rescind an acceleration
and its consequences with respect to all such series, including any related
payment default that resulted from such acceleration, but not including any
other payment default. Notwithstanding anything else in this Section, if
Securities of a series and of any applicable Pari Passu Series are held by one
or more Trusts: (1) any waiver described in this Section shall require the
consent of holders of the Trust Preferred Securities of such Trusts to the
extent provided in Section 9.02; (2) any rescission described in this Section
shall require the consent of the holders of a majority in aggregate liquidation
preference of the related Trust Preferred Securities; (3) if any consent is
given by the holders of Trust Preferred Securities under clause (1) or (2), no
separate consent shall be required from the Holders of the related series of
Securities; and (4) such series, all of the applicable Pari Passu Series and the
related Trust Preferred Securities shall be treated as a single class.

SECTION 6.05    CONTROL BY MAJORITY.

     Holders of a majority in principal amount of the then outstanding
Securities of all Pari Passu Series affected (treating all such series as a
single class) may direct the time, method and place of conducting any proceeding
for exercising any remedy available to the Trustee or exercising any trust or
power conferred on it; provided that

                                       31
<Page>

          (i)   such direction shall not be in conflict with any law or rule or
     with this Indenture;

          (ii)  the Trustee may take any other action deemed proper by the
     Trustee which is not inconsistent with such direction; and

          (iii) the Trustee need not take any action which might involve it in
     personal liability or be unduly prejudicial to the Holders of Securities of
     such series not joining therein;

     and provided, further, that in the case of a series and all Pari Passu
Series of Securities held by one or more Trusts, such direction may be made by
the holders of a majority in aggregate liquidation preference of the Trust
Preferred Securities then outstanding of Trusts holding such series of
Securities, treating the related Trust Preferred Securities as a single class.

SECTION 6.06    LIMITATION ON SUITS.

     A Holder of a Security of any series may pursue a remedy with respect to
this Indenture or the Securities of such series only if:

     (a)  the Holder of a Security of such series gives to the Trustee written
notice of a continuing Event of Default;

     (b)  the Holders of at least 25% in principal amount of the then
outstanding Securities of such series and of all Pari Passu Series affected
(treating all such series as a single class) make a written request to the
Trustee to pursue the remedy;

     (c)  such Holder or Holders offer and, if requested, provide to the Trustee
indemnity satisfactory to the Trustee against any loss, liability or expense;

     (d)  the Trustee does not comply with the request within 30 days after
receipt of the request and the offer and, if requested, the provision of
indemnity; and

     (e)  during such 30-day period the Holders of a majority in principal
amount of the then outstanding Securities of such series and of all Pari Passu
Series affected (treating all such series as a single class) do not give the
Trustee a direction inconsistent with the request.

     A Holder of a Security may not use this Indenture to prejudice the rights
of another Holder of a Security or to obtain a preference or priority over
another Holder of a Security.

SECTION 6.07    RIGHTS OF HOLDERS OF SECURITIES TO RECEIVE PAYMENT.

     Notwithstanding any other provision of this Indenture, the right of any
Holder of a Security of any series to receive payment of principal, premium, if
any, and interest on such Security, and any additional amounts payable pursuant
to Section 4.09 or otherwise under this Indenture, any Board Resolution or any
indenture supplemental hereto, on or after the respective due dates expressed in
such Security (including in connection with an offer to purchase), or to

                                       32
<Page>

bring suit for the enforcement of any such payment on or after such respective
dates, shall not be impaired or affected without the consent of such Holder.

SECTION 6.08    COLLECTION SUIT BY TRUSTEE.

     If an Event of Default specified in Section 6.01(a) or (b) occurs and is
continuing with respect to any series of Securities, the Trustee is authorized
to recover judgment in its own name and as Trustee of an express trust against
the Company for the whole amount of principal of, premium, if any, and interest
remaining unpaid on such Securities and interest on overdue principal and, to
the extent lawful, interest and such further amount as shall be sufficient to
cover the costs and expenses of collection, including the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel.

SECTION 6.09    TRUSTEE MAY FILE PROOFS OF CLAIM.

     The Trustee is authorized 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 the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel) and the
Holders of the Securities of any series allowed in any judicial proceedings
relative to the Company (or any other obligor upon the Securities), its
creditors or its property and shall be entitled and empowered to collect,
receive and distribute any money or other property payable or deliverable on any
such claims and any custodian in any such judicial proceeding is hereby
authorized by each Holder 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
Holders, to pay to the Trustee any amount due to it for the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel, and any other amounts due the Trustee under Section 7.07 hereof. To
the extent that the payment of any such compensation, expenses, disbursements
and advances of the Trustee, its agents and counsel, and any other amounts due
the Trustee under Section 7.07 hereof out of the estate in any such proceeding,
shall be denied for any reason, payment of the same shall be secured by a lien
on, and shall be paid out of, any and all distributions, dividends, money,
securities and other properties that the Holders may be entitled to receive in
such proceeding whether in liquidation or under any plan of reorganization or
arrangement or otherwise. Nothing herein contained shall be deemed to authorize
the Trustee to authorize or consent to or accept or adopt on behalf of any
Holder any plan of reorganization, arrangement, adjustment or composition
affecting the Securities of any series or the rights of any Holder, or to
authorize the Trustee to vote in respect of the claim of any Holder in any such
proceeding.

SECTION 6.10    PRIORITIES.

     If the Trustee collects any money or other property pursuant to this
Article, it shall pay out the money or other property in the following order:

     FIRST: to the Trustee, its agents and attorneys for amounts due under
Section 7.07 hereof, including payment of all compensation, expense and
liabilities incurred, and all advances made, by the Trustee and the costs and
expenses of collection;

                                       33
<Page>

     SECOND: to Holders of Securities for amounts due and unpaid on the
Securities for principal, premium, if any, interest and any other amounts,
ratably, without preference or priority of any kind, according to the amounts
due and payable on the Securities for principal, premium, if any, interest and
other amounts, respectively; and

     THIRD: to the Company or to such party as a court of competent jurisdiction
shall direct.

     The Trustee may fix a record date and payment date for any payment to
Holders of Securities pursuant to this Section 6.10.

SECTION 6.11    UNDERTAKING FOR COSTS.

     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 a
Trustee, a court in its discretion may require the filing by any party litigant
in the suit of an undertaking to pay the costs of the suit, and the court in its
discretion may assess reasonable costs, including reasonable attorneys' fees,
against any party litigant in the suit, having due regard to the merits and good
faith of the claims or defenses made by the party litigant. This Section does
not apply to a suit by the Trustee, a suit by a Holder of a Security pursuant to
Section 6.07 hereof, or a suit by Holders of more than 10% in principal amount
of the then outstanding Securities of any series.

                                    ARTICLE 7
                                     TRUSTEE

SECTION 7.01    DUTIES OF TRUSTEE.

     (a)  If an Event of Default has occurred and is continuing, the Trustee
shall exercise such of the rights and powers vested in it by this Indenture or
an indenture supplemental hereto, and use the same degree of care and skill in
its exercise, as a prudent person would exercise or use under the circumstances
in the conduct of its own affairs.

     (b)  Except during the continuance of an Event of Default:

          (i)   the duties of the Trustee shall be determined solely by the
     express provisions of this Indenture or an indenture supplemental hereto,
     and the Trustee need perform only those duties that are specifically set
     forth in this Indenture or an indenture supplemental hereto and no others,
     and no implied covenants or obligations shall be read into this Indenture
     or an indenture supplemental hereto against the Trustee; and

          (ii)  in the absence of bad faith on its part, the Trustee may
     conclusively rely, as to the truth of the statements and the correctness of
     the opinions expressed therein, upon certificates or opinions furnished to
     the Trustee and conforming to the requirements of this Indenture. However,
     the Trustee shall examine the certificates and opinions to determine
     whether or not they conform to the requirements of this Indenture.

     (c)  The Trustee may not be relieved from liabilities for its own negligent
action, its own negligent failure to act, or its own willful misconduct, except
that:

                                       34
<Page>

          (i)   this paragraph does not limit the effect of paragraph (b) of
     this Section;

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

          (iii) the Trustee shall not be liable with respect to any action it
     takes or omits to take in good faith in accordance with a direction
     received by it pursuant to Section 6.05 hereof.

     (d)  Whether or not therein expressly so provided, every provision of this
Indenture that in any way relates to the Trustee is subject to paragraphs (a),
(b), and (c) of this Section.

     (e)  No provision of this Indenture shall require the Trustee to expend or
risk its own funds or incur any liability. The Trustee shall be under no
obligation to exercise any of its rights and powers under this Indenture at the
request of any Holders, unless such Holders shall have offered to the Trustee
security and indemnity satisfactory to it against any loss, liability or
expense.

     (f)  The Trustee shall not be liable for interest on any money received by
it except as the Trustee may agree in writing with the Company. Money held in
trust by the Trustee need not be segregated from other funds except to the
extent required by law.

SECTION 7.02    RIGHTS OF TRUSTEE.

     (a)  The Trustee may conclusively rely upon any document believed by it to
be genuine and to have been signed or presented by the proper Person. The
Trustee need not investigate any fact or matter stated in the document.

     (b)  Before the Trustee acts or refrains from acting, it may require an
Officers' Certificate or an Opinion of Counsel or both. The Trustee shall not be
liable for any action it takes or omits to take in good faith in reliance on
such Officers' Certificate or Opinion of Counsel. The Trustee may consult with
counsel, and the written advice of such counsel or any Opinion of Counsel shall
be full and complete authorization and protection from liability in respect of
any action taken, suffered or omitted by it hereunder in good faith and in
reliance thereon.

     (c)  The Trustee may act through its attorneys and agents and shall not be
responsible for the misconduct or negligence of any agent appointed with due
care.

     (d)  The Trustee shall not be liable for any action it takes or omits to
take in good faith that it believes to be authorized or within the rights or
powers conferred upon it by this Indenture.

     (e)  Unless otherwise specifically provided in this Indenture, any demand,
request, direction or notice from the Company shall be sufficient if signed by
an Officer of the Company.

     (f)  The Trustee shall be under no obligation to exercise any of the rights
or powers vested in it by this Indenture at the request or direction of any of
the Holders unless such Holders shall have offered to the Trustee reasonable
security or indemnity satisfactory to it against the costs, expenses and
liabilities that might be incurred by it in compliance with such request or
direction.

SECTION 7.03    INDIVIDUAL RIGHTS OF TRUSTEE.

     The Trustee in its individual or any other capacity may become the owner or
pledgee of Securities and may otherwise deal with the Company or any Affiliate
of the Company with the same rights it would have if it were not Trustee.
However, in the event that the Trustee acquires any conflicting interest (within
the meaning of TIA ss. 310(b)) it must eliminate such conflicting interest
within 90 days after Default, apply to the SEC for permission to continue as
trustee, or resign. Any Agent may do the same with like rights and duties.

SECTION 7.04    TRUSTEE'S DISCLAIMER.

     The Trustee shall not be responsible for and makes no representation as to
the validity or adequacy of this Indenture or the Securities; it shall not be
accountable for the Company's use of the proceeds from the Securities or any
money paid to the Company or upon the Company's direction under any provision of
this Indenture; it shall not be responsible for the use or application of any
money received by any Paying Agent other than the Trustee; and it shall not be
responsible for any statement or recital herein or any statement in the
Securities or any other document in connection with the sale of the Securities
or pursuant to this Indenture other than its certificate of authentication.

SECTION 7.05    NOTICE OF DEFAULTS.

     If a Default or Event of Default occurs and is continuing and if a
Responsible Officer of the Trustee has actual knowledge of such Default or Event
of Default, the Trustee shall mail to Holders of Securities a notice of the
Default or Event of Default within 90 days after it occurs. Except in the case
of a Default or Event of Default in payment of principal of, or interest on, any
Security, the Trustee may withhold the notice if and so long as a committee of
its Responsible Officers in good faith determines that withholding the notice is
in the interests of the Holders of the Securities.

SECTION 7.06    REPORTS BY TRUSTEE TO HOLDERS OF THE SECURITIES.

     On or before July 31 of each year, beginning with the July 31 following the
date on which Securities are first issued under this Indenture, and for so long
as Securities remain outstanding, the Trustee shall mail to the Holders of the
Securities a brief report dated as of such reporting date that complies with TIA
ss. 313(a) (but if no event described in TIA ss. 313(a) has occurred within the
twelve months preceding the reporting date, no report need be transmitted). The
Trustee also shall comply with TIA ss. 313(b)(2). The Trustee shall also
transmit by mail all reports as required by TIA ss. 313(c). A copy of each
report at the time of its mailing to the Holders of Securities shall be mailed
to the Company and filed with the SEC and each stock exchange on which the
Securities are listed in accordance with TIA ss. 313(d). The Company shall
promptly notify the Trustee when the Securities are listed on any stock
exchange.

                                       36

SECTION 7.07    COMPENSATION AND INDEMNITY.

     The Company shall pay to the Trustee from time to time such compensation
for its acceptance of this Indenture and services hereunder as the Company and
Trustee have separately agreed. The Trustee's compensation shall not be limited
by any law on compensation of a trustee of an express trust. The Company shall
reimburse the Trustee promptly upon request for all reasonable disbursements,
advances and expenses incurred or made by it in addition to the compensation for
its services. Such expenses shall include the reasonable compensation,
disbursements and expenses of the Trustee's agents and counsel.

     The Company shall indemnify the Trustee against any and all losses,
liabilities or expenses incurred by it arising out of or in connection with the
acceptance or administration of its duties under this Indenture, including the
costs and expenses of enforcing this Indenture against the Company (including
this Section 7.07) and defending itself against any claim (whether asserted by
the Company or any Holder or any other person) or liability in connection with
the exercise or performance of any of its powers or duties hereunder, except to
the extent any such loss, liability or expense may be attributable to its
negligence or willful misconduct. The Trustee shall notify the Company promptly
of any claim for which it may seek indemnity. Failure by the Trustee to so
notify the Company shall not relieve the Company of its obligations hereunder.
The Company shall defend the claim, and the Trustee shall cooperate in the
defense. The Trustee may have separate counsel, and the Company shall pay the
reasonable fees and expenses of such counsel. The Company need not pay for any
settlement made without its consent, which consent shall not be unreasonably
withheld.

     The obligations of the Company under this Section 7.07 shall survive the
satisfaction and discharge of this Indenture, and the removal or resignation of
the Trustee.

     To secure the Company's payment obligations in this Section, the Trustee
shall have a lien prior to the Securities on all money or property held or
collected by the Trustee, except that held in trust to pay principal of,
premium, if any, and interest on particular Securities. Such lien shall survive
the satisfaction and discharge of this Indenture.

     When the Trustee incurs expenses or renders services after an Event of
Default specified in Section 6.01(e) or (f) hereof occurs, the expenses and the
compensation for the services (including the fees and expenses of its agents and
counsel) are intended to constitute expenses of administration under any
Bankruptcy Law.

SECTION 7.08    REPLACEMENT OF TRUSTEE.

     A resignation or removal of the Trustee and appointment of a successor
Trustee shall become effective only upon the successor Trustee's acceptance of
appointment as provided in this Section.

     The Trustee may resign with respect to one or more or all series of
Securities at any time and be discharged from the trust hereby created by so
notifying the Company in writing. The Holders of a majority in principal amount
of the then outstanding Securities of any series may remove the Trustee with
respect to such series by so notifying the Trustee and the Company in writing.
The Company may remove the Trustee if:

                                       37
<Page>

     (a)  the Trustee ceases to be eligible in accordance with Section 7.10
hereof;

     (b)  the Trustee is adjudged bankrupt or insolvent or an order for relief
is entered with respect to the Trustee under any Bankruptcy Law;

     (c)  a custodian or public officer takes charge of the Trustee or its
property; or

     (d)  the Trustee becomes incapable of acting.

     If the Trustee resigns or is removed or if a vacancy exists in the office
of Trustee for any reason, the Company shall promptly appoint a successor
Trustee. Within one year after the successor Trustee takes office, the Holders
of a majority in principal amount of the then outstanding Securities of a series
may appoint a successor Trustee to replace the successor Trustee appointed by
the Company with respect to that series of Securities.

     If a successor Trustee does not take office within 60 days after the
retiring Trustee resigns or is removed, the retiring Trustee, the Company, or
the Holders of at least 10% in principal amount of the then outstanding
Securities may petition any court of competent jurisdiction for the appointment
of a successor Trustee.

     If the Trustee, after written request by any Holder of a Security who has
been a Holder of a Security for at least six months, ceases to be eligible in
accordance with Section 7.10, such Holder of a Security may petition any court
of competent jurisdiction for the removal of the Trustee and the appointment of
a successor Trustee. A successor Trustee shall deliver a written acceptance of
its appointment to the retiring Trustee and to the Company. Thereupon, the
resignation or removal of the retiring Trustee shall become effective, and the
successor Trustee shall have all the rights, powers and duties of the Trustee
under this Indenture. The successor Trustee shall mail a notice of its
succession to Holders of the Securities. The retiring Trustee shall promptly
transfer all property held by it as Trustee to the successor Trustee, PROVIDED
all sums owing to the Trustee hereunder have been paid and subject to the lien
provided for in Section 7.07 hereof. Notwithstanding replacement of the Trustee
pursuant to this Section 7.08, the Company's obligations under Section 7.07
hereof shall continue for the benefit of the retiring Trustee.

     If a successor Trustee is appointed with respect to the Securities of one
or more (but not all) series, the Company, the retiring Trustee and each
successor Trustee with respect to the Securities of any applicable series shall
execute and deliver an indenture supplemental hereto which shall contain such
provisions as shall be deemed necessary or desirable to confirm that all the
rights, powers, trusts and duties of the retiring Trustee with respect to the
Securities of any series as to which the predecessor Trustee is not retiring
shall continue to be vested in the predecessor Trustee, and shall add to or
change any of the provisions of this Indenture as shall be necessary to provide
for or facilitate the administration of the trusts hereunder by more than one
Trustee, it being understood that nothing herein or in such supplemental
indenture shall constitute such Trustees as co-trustees of the same trust and
that each such Trustee shall be Trustee of a trust or trusts hereunder separate
and apart from any trust or trusts hereunder administered by any other such
Trustee.

SECTION 7.09    SUCCESSOR TRUSTEE BY MERGER, ETC.

     If the Trustee consolidates, merges or converts into, or transfers all or
substantially all of its corporate trust business to, another corporation, the
successor corporation without any further act shall be the successor Trustee.

SECTION 7.10    ELIGIBILITY; DISQUALIFICATION.

     There shall at all times be a Trustee hereunder that is a corporation
organized and doing business under the laws of the United States of America or
of any state thereof that is authorized under such laws to exercise corporate
trust powers, that is subject to supervision or examination by federal or state
authorities and that has a combined capital and surplus of at least $50,000,000
as set forth in its most recent published annual report of condition.

     This Indenture shall always have a Trustee who satisfies the requirements
of TIA ss. 310(a)(1), (2) and (5). The Trustee is subject to TIA ss. 310(b).

SECTION 7.11    PREFERENTIAL COLLECTION OF CLAIMS AGAINST COMPANY.

     The Trustee is subject to TIA ss. 311(a), excluding any creditor
relationship described in TIA ss. 311(b). A Trustee who has resigned or been
removed shall be subject to TIA ss. 311(a) to the extent indicated therein.

                                    ARTICLE 8
                    LEGAL DEFEASANCE AND COVENANT DEFEASANCE;
                           SATISFACTION AND DISCHARGE

SECTION 8.01    OPTION TO EFFECT LEGAL DEFEASANCE OR COVENANT DEFEASANCE;
                ALTERNATIVE SATISFACTION AND DISCHARGE.

     (a)  The Company may, at the option of its Board of Directors evidenced by
a resolution set forth in an Officers' Certificate, at any time, elect to have
either Section 8.02 or 8.03 hereof, with such modifications thereto as may be
specified in the Board Resolution or supplemental indenture establishing a
particular series of Securities, be applied to all outstanding Securities of one
or more series upon compliance with the conditions set forth below in this
Article 8.

     (b)  As an alternative to having Section 8.02 or 8.03 be applied to all
outstanding Securities of one or more series, the Company may terminate its
obligations under the Securities of one or more series and its obligations under
this Indenture in respect of such series of Securities (except those obligations
referred to in the penultimate paragraph of this Section 8.01(b), and any
obligation of the Company to convert or exchange Securities of such series as
expressly provided for in the Board Resolution or indenture supplemental hereto
establishing such Series) (1) if (i) all Securities of such series theretofore
authenticated and delivered (except lost, stolen or destroyed Securities that
have been replaced or paid and Securities for whose

                                       39
<Page>

payment cash in United States dollars has theretofore been deposited in trust or
segregated and held in trust by the Company and thereafter repaid to the Company
or discharged from such trust as provided in Section 8.06) have been delivered
to the Trustee for cancellation; (ii) the Company has paid all sums payable by
it hereunder or under the applicable Board Resolution or indenture supplemental
hereto in respect of such series of Securities; and (iii) the Company shall have
delivered to the Trustee an Officer's Certificate and an Opinion of Counsel,
each stating that all conditions precedent relating to the satisfaction and
discharge of this Indenture have been complied with; or (2) if (i) either (A) in
the case of a series of Securities redeemable prior to its stated maturity, the
Company shall, pursuant to Article 3, have given notice to the Trustee and
mailed a notice of redemption to each Holder of Securities of such series of the
redemption of all of such Securities under arrangements satisfactory to the
Trustee for the giving of such notice or (B) all Securities of such series have
otherwise become due and payable hereunder or will become due and payable within
one year; (ii) the Company shall have irrevocably deposited or caused to be
deposited with the Trustee (or a trustee satisfactory to the Trustee, under the
terms of an irrevocable trust agreement in form and substance satisfactory to
the Trustee), as trust funds in trust solely for the benefit of the Holders of
Securities of such series for that purpose, cash in United States dollars in
such amount as is sufficient without consideration of reinvestment of interest
or other earnings on such cash, to pay the entire indebtedness on such
Securities not theretofore delivered to the Trustee for cancellation, for the
principal of, premium, if any, and interest on the outstanding Securities of
such series to the date of such deposit (in the case of Securities which have
become due and payable) or to the stated maturity or redemption date, as the
case may be; (iii) no Default or Event of Default with respect to this Indenture
or the Securities shall have occurred and be continuing on the date of such
deposit or shall occur as a result of such deposit and such deposit will not
result in a breach or violation of, or constitute a default under, any other
instrument to which the Company is bound; (iv) the Company shall have paid all
other sums payable by it hereunder in respect of Securities of such series; and
(v) the Company shall have delivered to the Trustee an Officers' Certificate and
an Opinion of Counsel, each stating that all conditions precedent relating to
the satisfaction and discharge of this Indenture have been complied with.
Notwithstanding the foregoing paragraph, the Company's obligations in Sections
2.07, 2.08, 2.09, 2.10, 4.01, including any provision of the applicable Board
Resolution or indenture supplemental hereto relating to the payment of
principal, premium or interest, 4.02, 7.07, 8.06 and 8.07 shall survive with
respect to the Securities of the applicable series until they are no longer
outstanding pursuant to the last paragraph of Section 2.10. After the Securities
of the applicable series are no longer outstanding, the Issuer's obligations in
Sections 7.07, 8.06 and 8.07 shall survive in respect of Securities of the
applicable series.

     After such delivery or irrevocable deposit, the Trustee upon request shall
acknowledge in writing the discharge of the Company's obligations under the
Securities of the applicable series and the Company's obligations under this
Indenture with respect to the Securities of such series, except for those
surviving obligations specified above.

SECTION 8.02    LEGAL DEFEASANCE AND DISCHARGE.

     Upon the Company's exercise under Section 8.01 hereof of the option
applicable to this Section 8.02 relating to one or more series of Securities,
the Company shall, upon the satisfaction of the conditions set forth in Section
8.04 hereof, be deemed to have been discharged from its obligations with respect
to all outstanding Securities of such series on the date the conditions set

                                       40
<Page>

forth below are satisfied (hereinafter, "LEGAL DEFEASANCE"). For this purpose,
Legal Defeasance means that the Company shall be deemed to have paid and
discharged the entire indebtedness represented by the outstanding Securities of
the applicable series, which shall thereafter be deemed to be "OUTSTANDING" only
for the purposes of Section 8.05 hereof and the other Sections of this Indenture
referred to in (a) and (b) below, and to have satisfied all of its other
obligations under the Securities of the applicable series and under the
provisions of this Indenture applicable to such series (and the Trustee, on
demand of and at the expense of the Company, shall execute proper instruments
acknowledging the same), except for the following provisions which shall survive
until otherwise terminated or discharged hereunder: (a) the rights of Holders of
outstanding Securities of the applicable series to receive solely from the trust
fund described in Section 8.04 hereof, and as more fully set forth in such
Section, payments in respect of the principal of, premium, if any, and interest,
on such Securities when such payments are due, (b) the Company's Obligations
with respect to such Securities under Article 2 and Section 4.02 hereof and with
respect to the payment of Additional Sums, if any, on such Securities as
contemplated by Section 4.09, (c) the rights, powers, trusts, duties and
immunities of the Trustee hereunder, and the Company's obligations in connection
therewith and (d) this Article 8. Subject to compliance with this Article 8, the
Company may exercise its option under this Section 8.02 notwithstanding the
prior exercise of its option under Section 8.03 hereof.

SECTION 8.03    COVENANT DEFEASANCE.

     Upon the Company's exercise under Section 8.01 hereof of the option
applicable to this Section 8.03 relating to one or more series of Securities,
the Company shall, upon the satisfaction of the conditions set forth in Section
8.04 hereof, be released from its obligations under the covenants contained in
Sections 4.03, 4.04, 4.05, 4.06 and 4.07 hereof with respect to the outstanding
Securities of the applicable series, and under any other covenants specified in
the supplemental indenture or other terms of the applicable series as covenants
to which this Section 8.03 apply, on and after the date the conditions set forth
below are satisfied (hereinafter, "COVENANT DEFEASANCE"), and the Securities of
the applicable series shall thereafter be deemed not "OUTSTANDING" for the
purposes of any direction, waiver, consent or declaration or act of Holders (and
the consequences of any thereof) in connection with such covenants, but shall
continue to be deemed "OUTSTANDING" for all other purposes hereunder (it being
understood that the Securities of the applicable series shall not be deemed
outstanding for accounting purposes). For this purpose, Covenant Defeasance
means that, with respect to the "OUTSTANDING" Securities of the applicable
series, the Company may omit to comply with and shall have no liability in
respect of any term, condition or limitation set forth in any such covenant,
whether directly or indirectly, by reason of any reference elsewhere herein to
any such covenant or by reason of any reference in any such covenant to any
other provision herein or in any other document and such omission to comply
shall not constitute a Default or an Event of Default under Section 6.01 hereof,
but, except as specified above, the remainder of this Indenture and such
Securities shall be unaffected thereby.

SECTION 8.04    CONDITIONS TO LEGAL OR COVENANT DEFEASANCE.

     The following shall be the conditions to the application of either Section
8.02 or 8.03 hereof to the outstanding Securities of one or more series:

                                       41
<Page>

     In order to exercise either Legal Defeasance or Covenant Defeasance:

     (a)  the Company must irrevocably deposit with the Trustee, (or another
trustee satisfying the requirements of Section 7.10, who shall agree to comply
with the provisions of this Article 8 applicable to it) in trust, for the
benefit of the Holders of the Securities of the applicable series, (i) an amount
of cash in United States dollars, (ii) non-callable U.S. Government Obligations
which, through scheduled payment of principal and interest in respect thereof in
accordance with their terms, will provide, not later than one Business Day
before the due date of any payment of principal of, premium, if any, or interest
on the Securities of such series, cash in an amount, or (iii) a combination
thereof, sufficient, in the opinion of a nationally recognized firm of
independent public accountants, to pay the principal of, interest and premium,
if any, on the outstanding Securities of the applicable series on the Stated
Maturity or on the applicable redemption date, as the case may be, and any
mandatory sinking fund payments applicable to the Securities of such series on
the day on which such payments are due, and the Company must specify whether the
Securities of the applicable series are being defeased to maturity or to a
particular redemption date;

     (b)  in the case of an election under Section 8.02 hereof, the Company
shall have delivered to the Trustee an Opinion of Counsel in the United States
reasonably acceptable to the Trustee confirming that (i) the Company has
received from, or there has been published by, the Internal Revenue Service a
ruling or (ii) since the date of this Indenture, there has been a change in the
applicable federal income tax law, in either case to the effect that, and based
thereon such Opinion of Counsel shall confirm that, the Holders of the
outstanding Securities of the applicable series will not recognize income, gain
or loss for federal income tax purposes as a result of such Legal Defeasance and
will be subject to federal income tax on the same amounts, in the same manner
and at the same times as would have been the case if such Legal Defeasance had
not occurred;

     (c)  in the case of an election under Section 8.03 hereof, the Company
shall have delivered to the Trustee an Opinion of Counsel in the United States
reasonably acceptable to the Trustee confirming that the Holders of the
outstanding Securities of the applicable series will not recognize income, gain
or loss for federal income tax purposes as a result of such Covenant Defeasance
and will be subject to federal income tax on the same amounts, in the same
manner and at the same times as would have been the case if such Covenant
Defeasance had not occurred;

     (d)  no Default or Event of Default shall have occurred and be continuing
on the date of such deposit (other than a Default or Event of Default resulting
from the borrowing of funds to be applied to such deposit) or insofar as
Sections 6.01(e) or (f) hereof are concerned, at any time in the period ending
on the 91st day after the date of deposit (or greater period of time in which
any such deposit of trust funds may remain subject to bankruptcy or insolvency
laws insofar as those apply to the deposit by the Company);

     (e)  the Company shall have delivered to the Trustee an Officers'
Certificate and an Opinion of Counsel, each stating that all conditions
precedent provided for or relating to the Legal Defeasance or the Covenant
Defeasance have been complied with.

SECTION 8.05    DEPOSITED MONEY AND U.S. GOVERNMENT OBLIGATIONS TO BE HELD IN
                TRUST; OTHER MISCELLANEOUS PROVISIONS.

     Subject to Section 8.06 hereof, all money and non-callable U.S. Government
Obligations (including the proceeds thereof) deposited with the Trustee (or
other qualifying trustee, collectively for purposes of this Section 8.05, the
"TRUSTEE") pursuant to Section 8.04 hereof in respect of the outstanding
Securities of the applicable series shall be held in trust and applied by the
Trustee, in accordance with the provisions of such Securities and this
Indenture, to the payment, either directly or through any Paying Agent
(including the Company acting as Paying Agent) as the Trustee may determine, to
the Holders of such Securities of all sums due and to become due thereon in
respect of principal, premium, if any, and interest, but such money need not be
segregated from other funds except to the extent required by law.

     The Company shall pay and indemnify the Trustee against any tax, fee or
other charge imposed on or assessed against the cash or non-callable U.S.
Government Obligations deposited pursuant to Section 8.04 hereof or the
principal and interest received in respect thereof other than any such tax, fee
or other charge which by law is for the account of the Holders of the
outstanding Securities of the applicable series.

     Anything in this Article 8 to the contrary notwithstanding, the Trustee
shall deliver or pay to the Company from time to time upon the request of the
Company any money or non-callable U.S. Government Obligations held by it as
provided in Section 8.04 hereof which, in the opinion of a nationally recognized
firm of independent public accountants expressed in a written certification
thereof delivered to the Trustee (which may be the opinion delivered under
Section 8.04(a) hereof), are in excess of the amount thereof that would then be
required to be deposited to effect an equivalent Legal Defeasance or Covenant
Defeasance of the applicable series.

SECTION 8.06    REPAYMENT TO COMPANY.

     Any money and U.S. Government Obligations deposited with the Trustee or any
Paying Agent, or then held by the Company, in trust for the payment of the
principal of, premium or interest on any Security and remaining unclaimed for
two years after such principal, and premium, if any, or interest has become due
and payable shall be paid to the Company on its request or (if then held by the
Company) shall be discharged from such trust; and the Holder of such Security
shall thereafter look only to the Company for payment thereof, and all liability
of the Trustee or such Paying Agent with respect to such money and U.S.
Government Obligations, and all liability of the Company as trustee thereof,
shall thereupon cease; PROVIDED, HOWEVER, that the Trustee or such Paying Agent,
before being required to make any such repayment, may at the expense of the
Company cause to be published once, in the NEW YORK TIMES and THE WALL STREET
JOURNAL (national edition), notice that such money remains unclaimed and that,
after a date specified therein, which shall not be less than 30 days from the
date of such notification or publication, any unclaimed balance of such money
then remaining will be repaid to the Company.

                                       43

SECTION 8.07    REINSTATEMENT.

     If the Trustee or Paying Agent is unable to apply any United States dollars
or non-callable U.S. Government Obligations deposited pursuant to Section 8.02
or 8.03 hereof, as the case may be, by reason of any order or judgment of any
court or governmental authority enjoining, restraining or otherwise prohibiting
such application, then the obligations of the Company under this Indenture and
the Securities shall be revived and reinstated as though no deposit had occurred
pursuant to Section 8.02 or 8.03 hereof until such time as the Trustee or Paying
Agent is permitted to apply all such money in accordance with Section 8.02 or
8.03 hereof, as the case may be; PROVIDED, HOWEVER, that, if the Company makes
any payment of principal of, premium or interest on any Security following the
reinstatement of its obligations, the Company shall be subrogated to the rights
of the Holders of such Securities to receive such payment from the money held by
the Trustee or Paying Agent.

                                    ARTICLE 9
                        AMENDMENT, SUPPLEMENT AND WAIVER

SECTION 9.01    WITHOUT CONSENT OF HOLDERS OF SECURITIES.

     Notwithstanding Section 9.02 of this Indenture, the Company and the Trustee
may amend or supplement this Indenture or the Securities without the consent of
any Holder of a Security:

     (a)  to evidence the succession of another Person to the Company, or
successive successions, and the assumption by the successor Person of the
covenants, agreements and obligations of the Company pursuant to Article 5
hereof;

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

     (c)  to provide for the issuance under this Indenture of Securities in
coupon form (including Securities registrable as to principal only) and to
provide for exchangeability of such Securities with the Securities issued
hereunder in fully registered form and to make all appropriate changes for such
purpose;

     (d)  to cure any ambiguity or to correct or supplement any provision
contained herein or in any supplemental indenture which may be defective or
inconsistent with any other provision contained herein or in any supplemental
indenture, or to make such other provisions in

                                       44
<Page>

regard to matters or questions arising under this Indenture; provided that any
such action shall not adversely affect the interests of the Holders of the
Securities;

     (e)  to evidence and provide for the acceptance of appointment hereunder by
a successor trustee with respect to the Securities of one or more series and to
add to or change any of the provisions of this Indenture as shall be necessary
to provide for or facilitate the administration of the trusts hereunder by more
than one trustee, pursuant to the requirements of Section 7.08;

     (f)  to make any change that does not adversely affect the rights of any
Holder; or

     (g)  to provide for the issuance of and establish the form and terms and
conditions of the Securities of any series, to establish the form of any
certifications required to be furnished pursuant to the terms of this Indenture
or any series of Securities, or to add to the rights of the Holders of any
series of Securities.

     Upon the request of the Company accompanied by a copy of a Board
Resolution, certified by the Secretary or an Assistant Secretary of the Company
to have been duly adopted by the Board of Directors and to be in full force and
effect on the date of the certificate, authorizing the execution of any such
amended or supplemental indenture, and upon receipt by the Trustee of the
documents described in Section 7.02 hereof, the Trustee shall join with the
Company in the execution of any amended or supplemental indenture authorized or
permitted by the terms of this Indenture and to make any further appropriate
agreements and stipulations that may be therein contained, but the Trustee shall
not be obligated to enter into such amended or supplemental indenture that
affects its own rights, duties or immunities under this Indenture or otherwise.

SECTION 9.02    WITH CONSENT OF HOLDERS OF SECURITIES.

     Except as provided below in this Section 9.02, the Company and the Trustee
may amend or supplement this Indenture, or the Securities of any series may be
amended or supplemented, with the consent of the Holders of a majority in
principal amount of the Securities then outstanding of all series affected by
such supplemental indenture (including, without limitation, consents obtained in
connection with a purchase of, or tender offer or exchange offer for,
Securities), and, subject to Sections 6.04 and 6.07 hereof, any existing Default
or Event of Default (other than a Default or Event of Default in the payment of
the principal of, premium or interest on the Securities) or compliance with any
provision of this Indenture or the Securities of such series may be waived with
the consent of the Holders of a majority in principal amount of the Securities
then outstanding of all series affected by such waiver (including, without
limitation, consents obtained in connection with a purchase of, or tender offer
or exchange offer for the Securities). Any amendment to the provisions of
Article 10 hereof will require the consent of the Holders of at least 75% in
aggregate principal amount of the Securities then outstanding of all affected
series (treating all series that are Pari Passu Series with respect to each
other as a single class), and in the case of Securities issued to one or more
Selective Capital Trusts, the holders of 75% in aggregate liquidation preference
of the related Trust Preferred Securities (treating all such securities as a
single class) if such amendment would adversely affect the rights of Holders of
the Securities.

                                       45
<Page>

     For purposes of determining the consent required under this Section 9.02:
(a) any consent by the Holders of Securities of a series held by a Trust shall
also require the consent of a majority or other applicable percentage in
liquidation preference of Trust Preferred Securities of such Trust; (b) if any
consent is given by holders of Trust Preferred Securities pursuant to clause
(a), no separate consent shall be required from the Holders of the related
series of Securities; and (c) all of the applicable series of Securities that
are Pari Passu Series, and all Trust Preferred Securities of the related Trusts,
shall be treated as a single class.

     Upon the request of the Company accompanied by a copy of a Board
Resolution, certified by the Secretary or an Assistant Secretary of the Company
to have been duly adopted by the Board of Directors and to be in full force and
effect on the date of the certificate, authorizing the execution of any such
amended or supplemental indenture, and upon the filing with the Trustee of
evidence satisfactory to the Trustee of the consent of the Holders of Securities
of each such series as aforesaid, and upon receipt by the Trustee of the
documents described in Section 7.02(b) hereof, the Trustee shall join with the
Company in the execution of such amended or supplemental indenture unless such
amended or supplemental indenture affects the Trustee's own rights, duties or
immunities under this Indenture or otherwise, in which case the Trustee may in
its discretion, but shall not be obligated to, enter into such amended or
supplemental indenture.

     It shall not be necessary for the consent of the Holders of Securities
under this Section 9.02 to approve the particular form of any proposed amendment
or waiver, but it shall be sufficient if such consent approves the substance
thereof.

     After an amendment, supplement or waiver under this Section 9.02 becomes
effective, the Company shall mail to the Holders of Securities of such series
affected thereby a notice briefly describing the amendment, supplement or
waiver. Any failure of the Company to mail such notice, or any defect therein,
shall not, however, in any way impair or affect the validity of any such amended
or supplemental indenture or waiver.

     However, without the consent of each Holder of Securities affected, and
each holder of the related Trust Preferred Securities affected, an amendment or
waiver may not:

     (a)  reduce the principal amount of the Securities of any series whose
Holders must consent to an amendment, supplement or waiver;

     (b)  reduce the principal of or change the fixed maturity of the principal
of, premium, if any, or mandatory sinking fund obligation, if any, with respect
to any Securities of any series or alter the provisions with respect to the
redemption of the Securities;

     (c)  reduce the rate of or change the time for payment of interest,
including default interest, on any Security of any series or change any
obligation of the Company to pay Additional Sums (except as contemplated by
Section 5.01 and permitted by Section 9.01(a));

     (d)  waive a Default or Event of Default in the payment of principal of or
interest or premium on the Securities of any series (except a rescission of
acceleration of the Securities by the Holders of a majority in aggregate
principal amount of the Securities of any one or more affected series and a
waiver of the payment default that resulted from such acceleration);

                                       46
<Page>

     (e)  make any Security of any series payable in currency other than that
stated in the Securities of such series;

     (f)  make any change in the provisions of this Indenture relating to
waivers of past Defaults or the rights of Holders of Securities to receive
payments of principal of or interest or premium on the Securities;

     (g)  waive a redemption payment with respect to any Security; or

     (h)  make any change in Section 6.04 or 6.07 hereof or in the amendment and
waiver provisions of Section 9.01 or this Section 9.02; or

     (i)  materially and adversely affect the interests of the holders of any of
the Trust Preferred Securities.

     PROVIDED FURTHER, that any amendment or waiver described in paragraphs (a)
through (i) above shall not be effective until each holder of the Trust
Preferred Securities of the Trust(s) holding such Securities shall have
consented to such amendment, waiver or supplement.

SECTION 9.03    COMPLIANCE WITH TRUST INDENTURE ACT.

     Every amendment or supplement to this Indenture or the Securities shall be
set forth in an amended or supplemental indenture that complies with the TIA as
then in effect.

SECTION 9.04    REVOCATION AND EFFECT OF CONSENTS.

     Until an amendment, supplement or waiver becomes effective, a consent to it
by a Holder of a Security is a continuing consent by the Holder of a Security
and every subsequent Holder of a Security or portion of a Security that
evidences the same debt as the consenting Holder's Securities, even if notation
of the consent is not made on any Securities. However, any such Holder of a
Security or subsequent Holder of a Security may revoke the consent as to its
Securities if the Trustee receives written notice of revocation before the date
the waiver, supplement or amendment becomes effective. An amendment, supplement
or waiver becomes effective in accordance with its terms and thereafter binds
every Holder.

SECTION 9.05    NOTATION ON OR EXCHANGE OF SECURITIES.

     The Trustee may place an appropriate notation about an amendment,
supplement or waiver on any Securities thereafter authenticated. The Company in
exchange for all Securities may issue and the Trustee shall authenticate new
Securities that reflect the amendment, supplement or waiver.

     Failure to make the appropriate notation or to issue new Securities shall
not affect the validity and effect of such amendment, supplement or waiver.

                                       47

SECTION 9.06    TRUSTEE TO SIGN AMENDMENTS, ETC.

     The Company may not sign an amendment or supplemental indenture until its
Board of Directors approves it. The Trustee shall sign any amendment or
supplemental indenture authorized pursuant to this Article 9 if the amendment or
supplement does not adversely affect the rights, duties, liabilities or
immunities of the Trustee. If it does, the Trustee may, but need not, sign it.
In signing or refusing to sign such amendment or supplemental indenture, the
Trustee shall be entitled to receive and shall be fully protected in relying
upon, an Officers' Certificate and an Opinion of Counsel as conclusive evidence
that such amendment or supplemental indenture is authorized or permitted by this
Indenture, that it is not inconsistent herewith, and that it will be valid and
binding upon the Company in accordance with its terms.

                                   ARTICLE 10
                                  SUBORDINATION

SECTION 10.01   AGREEMENT TO SUBORDINATE.

     (a)  The Company agrees, and each Holder by accepting a Security agrees,
that the Indebtedness evidenced by the Securities is subordinated in right of
payment, to the extent and in the manner provided in this Article, to the prior
payment in full of all Senior Debt (whether outstanding on the date hereof or
hereafter created, incurred, assumed or guaranteed), and that the subordination
is for the benefit of the holders of Senior Debt.

     (b)  If any holder of Senior Debt is required by any court or otherwise to
return to the Company, or any Custodian, trustee, or similar official acting in
relation to the Company, any amount paid by the Company to such holder of Senior
Debt, the provisions of this Article 10, to the extent theretofore discharged,
shall be reinstated in full force and effect; PROVIDED, HOWEVER, that any
amounts paid pursuant to this Indenture to Holders of Securities shall not be
subject to disgorgement pursuant to the provisions of this paragraph (b).

SECTION 10.02   CERTAIN DEFINITIONS.

     "DESIGNATED SENIOR DEBT" means (i) the Senior Bank Debt and (ii) any other
Senior Debt permitted under this Indenture the principal amount of which is at
least the amount specified in the applicable supplemental indenture and that has
been designated by the Company as "DESIGNATED SENIOR DEBT."

     "REPRESENTATIVE" means the indenture trustee or other trustee, agent or
representative for any Senior Debt.

     A "DISTRIBUTION" may consist of cash, securities or other property, by
set-off or otherwise.

                                       48
<Page>

SECTION 10.03   LIQUIDATION; DISSOLUTION; BANKRUPTCY.

     Upon any distribution to creditors of the Company in a liquidation or
dissolution of the Company or in a bankruptcy, reorganization, insolvency,
receivership or similar proceeding relating to the Company or its property, an
assignment for the benefit of creditors or any marshalling of the Company's
assets and liabilities:

     (1)  holders of Senior Debt shall be entitled to receive payment in full of
all Obligations due in respect of such Senior Debt (including interest after the
commencement of any such proceeding at the rate specified in the applicable
Senior Debt) before the Holders of Securities shall be entitled to receive any
payment with respect to the Securities (except that Holders may receive (i)
securities that are subordinated to at least the same extent as the Securities
to (a) Senior Debt and (b) any securities issued in exchange for Senior Debt and
(ii) payments and other distributions made from any defeasance trust created
pursuant to Section 8.05 hereof); and

     (2)  until all Obligations with respect to Senior Debt (as provided in
subsection (1) above) are paid in full, any distribution to which the Holders of
Securities would be entitled but for this Article shall be made to holders of
Senior Debt (except that Holders may receive (i) securities that are
subordinated to at least the same extent as the Securities to (a) Senior Debt
and (b) any securities issued in exchange for Senior Debt and (ii) payments and
other distributions made from any defeasance trust created pursuant to Section
8.05 hereof), as their interests may appear.

SECTION 10.04   DEFAULT ON DESIGNATED SENIOR DEBT.

     (a)  The Company may not make any payment or distribution to the Trustee or
any Holder in respect of the Securities and may not acquire from the Trustee or
any Holder any Securities for cash or property (other than (1) securities that
are subordinated to at least the same extent as the Securities to (A) Senior
Debt and (B) any securities issued in exchange for Senior Debt and (2) payments
and other distributions made from any defeasance trust created pursuant to
Section 8.05 hereof) until all principal and other Obligations with respect to
the Senior Debt have been paid in full if:

          (1)   a default in the payment of the principal of, premium, if any,
     or interest on Designated Senior Debt occurs and is continuing beyond any
     applicable grace period in the agreement, indenture or other document
     governing such Designated Senior Debt; or

          (2)   a default, other than a default specified in Section 10.04(a)
     (1), on Designated Senior Debt occurs and is continuing with respect to
     Designated Senior Debt that then permits holders of the Designated Senior
     Debt as to which such default relates to accelerate its maturity and the
     Trustee receives a notice of the default (a "PAYMENT BLOCKAGE NOTICE") from
     a Person who may give it pursuant to Section 10.12 hereof. If the Trustee
     receives any such Payment Blockage Notice, no subsequent Payment Blockage
     Notice shall be effective for purposes of this Section unless and until (I)
     at least 360 days shall have elapsed since the effectiveness of the
     immediately prior Payment Blockage Notice and (II) all scheduled payments
     of principal and premium, if

                                       49
<Page>

     any, and interest on the Securities that have come due (other than by
     reason of acceleration) have been paid in full in cash. No default
     described in this paragraph (2) that existed or was continuing on the date
     of delivery of any Payment Blockage Notice to the Trustee shall be, or be
     made, the basis for a subsequent Payment Blockage Notice.

     (b)  The Company may and shall resume payments on and distributions in
respect of the Securities and may acquire them:

          (i)   in the case of a default described in Section 10.04(a)(1),  upon
     the date on which the default is cured or waived, and

          (ii)  in the case of a default referred to in Section 10.04(a)(2)
     hereof, the earlier of the date on which such default is cured or waived or
     179 days after the date on which the applicable Payment Blockage Notice is
     received, unless the maturity of any Designated Senior Debt has been
     accelerated,

          (iii) if this Article otherwise permits the payment, distribution or
     acquisition at the time of such payment or acquisition.

SECTION 10.05   ACCELERATION OF SECURITIES.

     If payment of the Securities is accelerated because of an Event of Default,
the Company shall promptly notify holders of Senior Debt of the acceleration.

SECTION 10.06   WHEN DISTRIBUTION MUST BE PAID OVER.

     In the event that the Trustee or any Holder receives any payment of any
Obligations with respect to the Securities at a time when the Trustee or such
Holder, as applicable, has actual knowledge that such payment is prohibited by
Section 10.04 hereof, such payment shall be held by the Trustee or such Holder,
in trust for the benefit of, and shall be paid forthwith over and delivered,
upon written request, to, the holders of Senior Debt as their interests may
appear or their Representative under the indenture or other agreement (if any)
pursuant to which Senior Debt may have been issued, as their respective
interests may appear, for application to the payment of all Obligations with
respect to Senior Debt remaining unpaid to the extent necessary to pay such
Obligations in full in accordance with their terms, after giving effect to any
concurrent payment or distribution to or for the holders of Senior Debt.

     With respect to the holders of Senior Debt, the Trustee undertakes to
perform only such obligations on the part of the Trustee as are specifically set
forth in this Article 10, and no implied covenants or obligations with respect
to the holders of Senior Debt shall be read into this Indenture against the
Trustee. The Trustee shall not be deemed to owe any fiduciary duty to the
holders of Senior Debt, and shall not be liable to any such holders if the
Trustee shall pay over or distribute to or on behalf of Holders or the Company
or any other Person money or assets to which any holders of Senior Debt shall be
entitled by virtue of this Article 10, except if such payment is made as a
result of the willful misconduct or gross negligence of the Trustee.

                                       50
<Page>

SECTION 10.07   NOTICE BY COMPANY.

     The Company shall promptly notify the Trustee and the Paying Agent of any
facts known to the Company that would cause a payment of any Obligations with
respect to the Securities to violate this Article, but failure to give such
notice shall not affect the subordination of the Securities to the Senior Debt
as provided in this Article.

SECTION 10.08   SUBROGATION.

     After all Senior Debt is paid in full and until the Securities are paid in
full, Holders shall be subrogated (equally and ratably with all other
Indebtedness pari passu with the Securities) to the rights of holders of Senior
Debt to receive distributions applicable to Senior Debt to the extent that
distributions otherwise payable to the Holders have been applied to the payment
of Senior Debt. A distribution made under this Article to holders of Senior Debt
that otherwise would have been made to Holders is not, as between the Company
and Holders, a payment by the Company on the Senior Debt.

SECTION 10.09   RELATIVE RIGHTS.

     This Article defines the relative rights of Holders and holders of Senior
Debt. Nothing in this Indenture shall:

          (i)   impair, as between the Company and Holders, the obligation of
     the Company, which is absolute and unconditional, to pay principal of,
     premium, if any, and interest (including Additional Sums, if any) on the
     Securities in accordance with their terms;

          (ii)  affect the relative rights of Holders and creditors of the
     Company other than rights of Holders of the Securities in relation to
     holders of Senior Debt; or

          (iii) prevent the Trustee or any Holder from exercising its available
     remedies upon a Default or Event of Default, subject to the rights of
     holders and owners of Senior Debt to receive distributions and payments
     otherwise payable to Holders.

     If the Company fails because of this Article to pay principal of or
interest on a Security on the due date, the failure is still a Default or Event
of Default.

SECTION 10.10   SUBORDINATION MAY NOT BE IMPAIRED BY COMPANY.

     No right of any holder of Senior Debt to enforce the subordination of the
Indebtedness evidenced by the Securities shall be impaired by any act or failure
to act by the Company or any Holder or by the failure of the Company or any
Holder to comply with this Indenture.

SECTION 10.11   DISTRIBUTION OR NOTICE TO REPRESENTATIVE.

     Whenever a distribution is to be made or a notice given to holders of
Senior Debt, the distribution may be made and the notice given to their
Representative.

                                       51
<Page>

     Upon any payment or distribution of assets of the Company referred to in
this Article 10, the Trustee and the Holders shall be entitled to rely upon any
order or decree made by any court of competent jurisdiction or upon any
certificate of such Representative or of the liquidating trustee or agent or
other Person making any distribution to the Trustee or to the Holders for the
purpose of ascertaining the Persons entitled to participate in such
distribution, the holders of the Senior Debt 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 10.

SECTION 10.12   RIGHTS OF TRUSTEE AND PAYING AGENT.

     Notwithstanding the provisions of this Article 10 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 or distribution by
the Trustee, and the Trustee and any Paying Agent may continue to make payments
on the Securities, unless the Trustee shall have received at the Corporate Trust
Office of the Trustee at least five Business Days prior to the date of such
payment written notice of facts that would cause the payment of any Obligations
with respect to the Securities to violate this Article or a Responsible Officer
of the Trustee otherwise has actual knowledge of such facts. Only the Company or
a Representative may give the notice. Nothing in this Article 10 shall impair
the claims of, or payments to, the Trustee under or pursuant to Section 7.07
hereof.

     The Trustee in its individual or any other capacity may hold Senior Debt
with the same rights it would have if it were not Trustee. Any Agent may do the
same with like rights.

SECTION 10.13   AUTHORIZATION TO EFFECT SUBORDINATION.

     Each Holder of a Security by the Holder's acceptance thereof authorizes and
directs the Trustee on the Holder's behalf to take such action as may be
necessary or appropriate to effectuate the subordination as provided in this
Article 10, and appoints the Trustee to act as the Holder's attorney-in-fact for
any and all such purposes. If the Trustee does not file a proper proof of claim
or proof of debt in the form required in any proceeding referred to in Section
6.09 hereof at least 30 days before the expiration of the time to file such
claim, the agent under the Credit Facility (or in the absence of such agent, the
lender) is hereby authorized to file an appropriate claim for and on behalf of
the Holders of the Securities.

                                   ARTICLE 11
                      EXTENSION OF INTEREST PAYMENT PERIOD

SECTION 11.01   APPLICABILITY OF ARTICLE.

     This Article shall apply only to Securities of a series that are initially
issued to a Trust. It shall apply to Securities of all such series unless
otherwise provided or modified in the terms of such series established pursuant
to Section 2.02.

                                       52
<Page>

SECTION 11.02   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
Securities to which this Article applies, to defer payments of interest by
extending the interest payment period of such Securities for a period not
exceeding 10 consecutive semi-annual periods (if interest on Securities of such
series is payable semi-annually) or 20 consecutive quarterly periods (if
interest on Securities of such series is payable quarterly), including the first
such semi-annual or quarterly 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 for Securities of
such series or extend beyond the Stated Maturity of the principal of the
Securities of such series. 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 11.02, will bear interest thereon at the
stated rate of interest applicable to the Securities of such series, compounded
semi-annually (if interest on Securities of such series is payable
semi-annually) or quarterly (if interest on Securities of such series is payable
quarterly) 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 of such
series, including any Additional Interest and Compounded Interest (together,
"Deferred Interest") that shall be payable to the Holders of the Securities of
such series in whose names the Securities are registered in the 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 (if interest on Securities of such series is payable
semi-annually) or 20 consecutive quarterly periods (if interest on Securities of
such series is payable quarterly), including the first such semi-annual period
during such Extended Interest Payment Period, or end on a date other than an
Interest Payment Date or extend beyond the Stated Maturity of the principal of
the Securities of such series. 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 11.03   NOTICE OF EXTENSION.

     (a)  If a Trust is the only Holder of the Securities to which this Article
applies at the time the Company selects an Extended Interest Payment Period, the
Company shall give written notice to the Administrative Trustees and the
Property Trustee of such Selective Capital Trust, and to the Trustee, of its
selection of such Extended Interest Payment Period at least five Business Days
before the earlier of (i) the next succeeding date on which distributions on the
Trust Preferred Securities issued by such Trust are payable, or (ii) the date
such 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 Trust Preferred Securities issued by such Trust, but in any event at least
five Business Days before such record date.

                                       53
<Page>

     (b)  If a Trust is not the only Holder of the Securities to which this
Article applies 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 or quarterly period in which any notice is given
pursuant to paragraphs (a) or (b) of this Section 11.03 shall be counted as one
of the 10 semi-annual periods or 20 quarterly periods permitted in the maximum
Extended Interest Payment Period permitted under Section 11.03.

                                   ARTICLE 12

any series for any purpose specified in Section 12.01, to be held at such time

other place as the Trustee shall determine. Notice of every meeting of Holders

meeting and in general terms the action proposed to be taken at such meeting,
shall be given, in the manner provided in Section 13.02, not less than 20 nor

of any series shall have requested the Trustee to call a meeting of the Holders
of Securities of such series for any purpose specified in Section 12.01 by
written request setting forth in reasonable detail the action proposed to be
taken at the meeting, and the Trustee shall not have mailed notice of such
meeting within 20 days after receipt of such request or shall not thereafter
proceed to cause the meeting to be held as provided herein, then the Company or
the Holders of Securities of such series in the amount above specified, as the
case may be, may determine the time and the place for such meeting and may call
such meeting for such purposes by giving notice thereof as provided in clause
(a) of this Section.

outstanding Securities of a series shall constitute a quorum for a meeting of
Holders of Securities of such series; provided, however, that if any action is
to be taken at such meeting with respect to a consent or waiver which this
Indenture (or any Board Resolution or indenture supplemental hereto establishing
a series of Securities hereunder) expressly provides may be given by the Holders
of more or less than a majority in principal amount of the outstanding
Securities of a series, the Persons entitled to vote such percentage in
principal amount of the outstanding Securities of such series shall constitute a
quorum. In the absence of a quorum within 30 minutes after the time appointed
for any such meeting, the meeting shall, if convened at the request of Holders
of Securities of such series, be dissolved. In any other case the meeting may be
adjourned for a period of not less than 10 days as determined by the chairman of
the meeting prior to the adjournment of such meeting. In the absence of a quorum
at any such adjourned meeting, such adjourned meeting may be further adjourned
for a period of not less than 10 days as determined by the chairman of the
meeting prior to the adjournment of such adjourned meeting. Notice of the
reconvening of any such adjourned meeting shall be given as provided in Section
12.02(a), except that such notice need be given only once not less than five
days prior to the date on which the meeting is scheduled to be reconvened.
Notice of the reconvening of an adjourned meeting shall state expressly the
percentage, as provided above, of the principal amount of the outstanding
Securities of such series which shall constitute a quorum.

     Except as otherwise provided in Section 6.02 or 9.02 (or in any Board
Resolution or indenture supplemental hereto establishing a series of Securities
hereunder), any resolution presented to a meeting or adjourned meeting duly
reconvened at which a quorum is present as aforesaid may be adopted only by the
affirmative vote of the Holders of a majority in principal amount of the
outstanding Securities of that series; provided, however, that, except as
otherwise provided in Section 6.02 or 9.02 (or in any Board Resolution or
indenture supplemental hereto establishing a series of Securities hereunder),
any resolution with respect to any request, demand, authorization, direction,
notice, consent, waiver or other action which this Indenture or any supplemental
indenture expressly provides may be made, given or taken by the Holders of a
specified percentage in principal amount of the outstanding Securities of a
series may be adopted at a meeting or an adjourned meeting duly reconvened and
at which a quorum is present as aforesaid by the affirmative vote of the Holders
of such specified percentage in principal amount of the outstanding Securities
of such series.

     (a)  Notwithstanding any other provisions of this Indenture, the Trustee
may make such reasonable regulations as it may deem advisable for any meeting of
Holders of Securities of a series in regard to proof of the holding of
Securities of such series and of the appointment of proxies and in regard to the
appointment and duties of inspectors of votes, the submission and examination of
proxies, certificates and other evidence of the right to vote, and such other
matters concerning the conduct of the meeting as it shall deem appropriate.
Except as otherwise permitted or required by any such regulations, the holding
of Securities shall be proved in the manner specified in Section 1.05 and the
appointment of any proxy shall be proved in the manner specified in Section
1.05. Such regulations may provide that written instruments appointing proxies,
regular on their face, may be presumed valid and genuine without the proof
specified in Section 1.05 or other proof.

     (b)  The Trustee shall, by an instrument in writing, appoint a temporary
chairman of the meeting, unless the meeting shall have been called by the
Company or by Holders of Securities as provided in Section 12.02(b), in which
case the Company or the Holders of Securities of the series calling the meeting,
as the case may be, shall in like manner appoint a temporary chairman. A
permanent chairman and a permanent secretary of the meeting shall be elected by
vote of the Persons entitled to vote at least a majority in principal amount of
the outstanding Securities of such series represented at the meeting.

     (c)  At any meeting each Holder of a Security of such series or proxy shall
be entitled to one vote for each $25 principal amount of the outstanding
Securities of such series held or represented by him; provided, however, that no
vote shall be cast or counted at any meeting in respect of any Security
challenged as not outstanding and ruled by the chairman of the meeting to be not
outstanding. The chairman of the meeting shall have no right to vote, except as
a Holder of a Security of such series or proxy.

     (d)  Any meeting of Holders of Securities of any series duly called
pursuant to Section 12.02 at which a quorum is present may be adjourned from
time to time by Persons entitled to vote at least a majority in principal amount
of the outstanding Securities of such series represented at the meeting; and the
meeting may be held as so adjourned without further notice.

SECTION 12.06   COUNTING VOTES AND RECORDING ACTION OF MEETINGS.

     The vote upon any resolution submitted to any meeting of Holders of
Securities of any series shall be by written ballots on which shall be
subscribed the signatures of the Holders of Securities of such series or of
their representatives by proxy and the principal amounts and serial numbers of
the outstanding Securities of such series held or represented by them. The
permanent chairman of the meeting shall appoint two inspectors of votes who
shall count all votes cast at the meeting for or against any resolution and who
shall make and file with the secretary of the

                                       56

inspectors of votes on any vote by ballot taken thereat and affidavits by one or
more persons having knowledge of the facts setting forth a copy of the notice of
the meeting and showing that said notice was given as provided in Section 12.02

affidavits of the permanent chairman and secretary of the meeting and one such
copy shall be delivered to the Company, and another to the Trustee to be
preserved by the Trustee, the latter to have attached thereto the ballots voted
at the meeting. Any record so signed and verified shall be conclusive evidence
of the matters therein stated.

enforce its rights under this Indenture as the Holder of the series of

Securities may institute legal proceedings directly against the Company to
enforce such Property Trustee's rights under this Indenture without first
instituting any legal proceedings against the 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 interest or principal on the applicable series of Securities on
the date such interest or principal is otherwise payable (or in the case of
redemption, on the redemption date), the Company acknowledges that a holder of
Trust Preferred Securities may directly institute a proceeding for enforcement
of payment to such holder of the principal of or interest on the applicable
series of Securities having a principal amount equal to the aggregate
liquidation preference of the Trust Preferred Securities of such holder on or
after the respective due date specified in the applicable series of Securities.

Holders of a majority in principal amount of the then outstanding Notes and
other series of Securities affected (treating the Notes and such other series as
a single class), and any existing default or compliance with any provision of
the Indenture, the Notes may be waived with the consent of the Holders of a
majority in principal amount of the then outstanding Notes and other series of

may be amended or supplemented to cure any ambiguity, defect or inconsistency,
to provide for uncertificated Notes in addition to or in place of certificated
Notes, to provide for the assumption of the Company's obligations to Holders of

provide any additional rights or benefits to the Holders of the Notes or that
does not adversely affect the legal rights under the Indenture of any such
Holder, or to comply with the requirements of the SEC in order to effect or
maintain the qualification of the Indenture under the TIA.

11.  DEFAULTS AND REMEDIES. Each of the following constitutes an Event of
Default: (i) default by the Company in the payment of interest on the Notes when
the same becomes due and payable and default continues for a period of 30 days;
(ii) default by the Company in the payment of the principal of or premium, if
any, on the Notes when the same becomes due and payable at maturity, upon
redemption or otherwise; (iii) failure by the Company to comply with Section
5.01 of the Indenture; (iv) failure by the Company for 60 days after notice to
comply with any of its other agreements in the Indenture or the Notes, (v)
certain events of bankruptcy or insolvency with respect to the Company; and (vi)
except in certain circumstances, the Trust holding this Note shall have
voluntarily dissolved. If any Event of Default occurs and is continuing, the
Trustee or the Holders of at least 25% in principal amount of the then
outstanding Notes and other series of Securities affected (treating the Notes
and such other series as a single class) may declare all the Notes to be due and
payable immediately. Notwithstanding the foregoing, in the case of an Event of
Default arising from certain events of bankruptcy or insolvency with respect to
the Company, all outstanding Notes will become due and payable without further
action or notice. Holders of the Notes may not enforce the Indenture or the
Notes except as provided in the Indenture. Subject to certain limitations,
Holders of a majority in principal amount of the then outstanding Notes and
other series of Securities affected (treating the Notes and such other series as
a single class) may direct the Trustee in its exercise of any trust or power.
The Trustee may withhold from Holders of the Notes notice of any continuing
Default or Event of Default (except a Default or Event of Default relating to
the payment of principal or interest) if it determines that withholding notice
is in their interest. The Holders of a majority in aggregate principal amount of
the Notes and other series of Securities affected (treating the Notes and such
other series as a single class) then outstanding by notice to the Trustee may on
behalf of the Holders of all of the Notes waive any existing Default or Event of
Default and its consequences under the Indenture except a continuing Default or
Event of Default in the payment of principal, interest or premium on the Notes.
The Company is required to deliver to the Trustee annually a statement regarding
compliance with the Indenture, and the

                                       A-4

Company is required upon becoming aware of any Default or Event of Default, to
deliver to the Trustee a statement specifying such Default or Event of Default.

12.  SUBORDINATION. Each Holder by accepting a Note agrees that the payment of
principal of, premium and interest on each Note is subordinated in right of
payment, to the extent and in the manner provided in the Indenture, to the prior
payment in full of all Senior Debt (whether outstanding on the date of the
Indenture or thereafter created, incurred, assumed or guaranteed), and that the
subordination is for the benefit of the holders of Senior Debt.

13.  TRUSTEE DEALINGS WITH THE COMPANY. The Trustee, in its individual or any
other capacity, may make loans to, accept deposits from, and perform services
for the Company or its Affiliates, and may otherwise deal with the Company or
its Affiliates, as if it were not the Trustee.

14.  NO RECOURSE AGAINST OTHERS. No director, officer, employee, incorporator or
stockholder of the Company shall have any liability for any obligations of the
Company under the Notes or the Indenture or for any claim based on, in respect
of, or by reason of, such obligations or their creation. Each Holder of Notes by
accepting a Note waives and releases all such liability. The waiver and release
are part of the consideration for the issuance of the Notes.

15.  AUTHENTICATION. This Note shall not be valid until authenticated by the
manual signature of the Trustee or an authenticating agent.

16.  ABBREVIATIONS. Customary abbreviations may be used in the name of a Holder
or an assignee, such as: TEN COM (= tenants in common), TEN ENT (= tenants by
the entireties), JT TEN (= joint tenants with right of survivorship and not as

17.  CUSIP NUMBERS. Pursuant to a recommendation promulgated by the Committee on
Uniform Security Identification Procedures, the Company has caused CUSIP numbers
to be printed on the Notes and the Trustee may use CUSIP numbers in notices of
redemption as a convenience to Holders. No representation is made as to the
accuracy of such numbers either as printed on the Notes or as contained in any
notice of redemption and reliance may be placed only on the other identification
numbers placed thereon.

charge a copy of the Indenture. Requests may be made to:
