                  NOW, THEREFORE, in consideration of the premises and of the
mutual agreements set forth herein, the parties hereto agree as follows:

                  1. EMPLOYMENT AND TERM. Subject to the terms and conditions of
this Agreement, and unless terminated as set forth herein, the Company agrees to

requested by the Board of Directors of the Company and under their direction.
During the Term, Executive shall (unless specifically agreed from time to time)
devote his entire business time, attention and energies, on a full-time basis,

Executive, in equal installments no less frequently than twice per month (or at
such other intervals as are in effect from time to time for other executive
employees of the Company), a m onthly base salary of (pound)8,000 Pounds
Sterling (such amount, as the same may hereafter be modified by mutual agreement
of Executive and the Company, to be reviewed once per year, being referred to
herein as the "Base Salary"). In addition, Executive may be awarded, at the
Company's sole and exclusive discretion, bonus compensation. Any such bonus
compensation shall be payable at such times as the Company may determine, but

                  c. REIMBURSEMENT OF EXPENSES. Executive shall be entitled to
reimbursement for all normal and reasonable travel, entertainment and other
expenses necessarily incurred by him in the performance of his duties hereunder.
Executive shall submit on a timely basis such itemized accounts of such
expenses, together with such vouchers or receipts for individual expense items,
as the Company may from time to time require under its established policies and
procedures. The Company's payments hereunder shall be made within a reasonable
time following its receipt of such itemized accounts.

                  d. VACATION. Executive shall be entitled to 5 weeks' vacation
each calendar year during the Term (such period to be pro-rated based on the
actual number of working days for which Executive is employed during a calendar
year). Executive shall be entitled to additional compensation for any vacation
time not taken in respect of any calendar year, and Executive shall be entitled
to carry over into any succeeding year any unused vacation time.

                  e. DISABILITY. Except as hereinafter provided, the Company
shall pay Executive, for any period (up to a maximum of six months during the
Term) in which he is unable fully to perform his duties because of physical or
mental disability or incapacity, an amount equal to the Base Salary due him for
such period pursuant to Section 3(a), less the aggregate amount of all income
disability benefits which for such period he may receive by reason of (i) any
group health insurance plan, or disability insurance plan paid for by the
Company, in each case which is intended to function as a salary replacement
plan, (ii) any applicable compulsory state disability law, (iii) any Social
Security Act, (iv) any applicable workmen's compensation law or similar law and
(v) any plan towards which the Company or any subsidiary or affiliate of the
Company (including any predecessor of any thereof) has contributed or for which
it has made payroll deductions, such as group accident or health policies, other
than those that reimburse for actual medical expenses.

                  f. KEY MAN INSURANCE. Executive agrees that the Company may
obtain key man life insurance with respect to Executive, and in connection
therewith, agrees to submit to all reasonable and customary examinations by the
provider of such life insurance.

                  a. CAUSE. The Company shall have the right, at any time
effective upon notice to Executive, to terminate Executive's employment for
"Cause," defined, for purposes hereof, as (i) malfeasance, gross neglect or
willful misconduct in the performance of Executive's duties hereunder; (ii)
conviction of a felony; (iii) failure to perform any of Executive's material
obligations under this Agreement (other than by reason of death or disability
contemplated by Section 3(e) or 4); (iv) fraud, dishonesty or unlawful conduct
against the Company or any of its or its affiliates' employees; or (v) a
material breach of this Agreement by Executive; PROVIDED, in the case of any
default under clause (iii), (iv) or (v) that is susceptible to cure, that such
default continues uncured 30 days after written notice thereof from the
Company to Executive.

                  b. DISABILITY; DEATH. In the event that Executive, due to
physical or mental disability or incapacity, is unable to substantially perform
his duties hereunder for a period of more than six months during the Term, the
Company or Executive shall have the right to terminate this Agreement and
Executive's employment hereunder upon 30 days' prior written notice and

terminate immediately upon his death.

                  c. TERMINATION BY EXECUTIVE FOR GOOD REASON. Executive may
terminate his employment hereunder, such termination to be effective on written
notice to the Company, for any of the following reasons:

                  (i) the assignment to Executive of any duties inconsistent in
        any material respect with Executive's position (including status,
        office, titles and reporting requirements), authority, duties or
        responsibilities as contemplated by this Agreement, or any other action
        by the Company which results in a material diminution in such position,
        authority, duties or responsibilities; or

                  (ii) the Company materially breaches its obligations under
        this Agreement; PROVIDED that any such action or default shall not have
        been remedied by the Company within 15 days after receipt of notice
        thereof given by Executive.

                  d. VOLUNTARY TERMINATION BY EXECUTIVE. Executive may terminate
his employment under this Agreement on six months' written notice to the Company
at any time.

                  5. EFFECTS OF TERMINATION.

                  e. Executive's obligations pursuant to Sections 6 and 7 hereof
shall survive any termination of this Agreement for any reason whatsoever.

                  6. CONFIDENTIALITY.

Executive's employment with the Company, he shall necessarily become informed
of, and shall have access to, confidential information of the Company,
including, without limitation, the contents of this Agreement, inventions, trade
secrets, technical information, know-how, plans, marketing plans and
information, pricing information, identity of providers and their patients and
prospective providers and their patients and identity of suppliers, and that
such information, even though it may be developed or otherwise acquired by
Executive, is the exclusive property of the Company to be held by Executive in a
fiduciary capacity and solely for the Company's benefit. Executive shall not at
any time, either during or subsequent to his employment hereunder, reveal,
report, publish, transfer or otherwise disclose to any person, company or other
entity, or use for his own benefit, any of the Company's confidential
information which Executive, in the exercise of reasonable diligence, knows or
should know to be confidential, without the written consent of the Company,
except for use on behalf of the Company in connection with the

                                      -4-

<PAGE>

Business, and except for such information which is or becomes of general public
knowledge from authorized sources other than Executive.

                  b. Upon the termination of his employment with the Company for
any reason, Executive shall promptly deliver to the Company all manuals,
letters, notes, notebooks, reports, documents and copies thereof and all other
materials, containing secret or confidential information, relating to the
Business that are in Executive's possession or control. For purposes of this
Section 6, the term "Company" includes the Company, any predecessor company, and
any of their respective affiliates.

                  7. NON-COMPETITION.

                  a. Subject to the provisions of paragraph (b) hereof,
Executive agrees that, for the period commencing on the date hereof and ending
two years after the termination of his employment with the Company for any
reason, he shall not, in any country in the world in which the Company then
engages in the Business (or in such lesser area or for such lesser period as may
be determined by a court of competent jurisdiction to be a reasonable limitation
on the competitive activity of Executive), directly or indirectly:

                  (i) engage, as an employee, officer, independent contractor or
        in any other capacity, in any activity for or on behalf of any person or
        entity (other than the Company) in a line of business competitive with
        the Business or any aspect thereof or engage in any manner in the
        Business;

                  (ii) except for the benefit of the Company, solicit or attempt
        to solicit business of entities who were providers for, or customers of,
        the Company at any time within the prior two years (including
        prospective providers or customers solicited by the Company) for
        products or services the same or similar to those offered, sold,
        produced or under development by the Company, or dealt in by Executive,
        during his employment therewith;

                  (iii) interfere with the Company, the Business or the conduct
        thereof by the Company, or otherwise divert or attempt to divert from
        the Company any business whatsoever;

                  (iv) hire, solicit or attempt to solicit for participation or
        employment in any business endeavor any employee of the Company;

                  (v) use the name of the Company or any name used by the
        Company, or any name similar to any thereof, whether or not registered;
        or

                  (vi) render any services as an officer, director, employee,
        partner, consultant or otherwise to, or have any interest as a member,
        stockholder, partner, lender or otherwise in, any person or entity that
        is engaged in activities which, if performed by Executive, would violate
        this Section 7.

                                      -5-

<PAGE>

The foregoing shall not prevent Executive from purchasing up to five percent of
the voting securities of any other entity, the securities of which are
publicly-traded, during the time which the Executive is actively employed by the
Company.

                  b. In the event Executive's employment is terminated under the
circumstances contemplated by paragraphs (c) or (d) of Section 5, the
obligations of Executive set forth under this Section 7 shall only continue in
effect so long as the Company continues to pay to Executive his Base Salary (in
the intervals set forth in Section 3(a)) during the one-year period following
termination of such employment.

                  c. Executive agrees that the restrictions on competition set
forth in this Section 7 are reasonable and are properly required for the
adequate protection of the Business of the Company. Executive represents that
his experience, capabilities and circumstances are such that the provisions
of this Section 7 will not prevent him from earning an appropriate livelihood.

                  8. REMEDIES AND SURVIVAL. The provisions of Sections 5 through
8 of this Agreement shall survive any termination of Executive's employment with
the Company.

                  9. ENTIRE AGREEMENT. This Agreement sets forth the entire
understanding of the parties hereto with respect to its subject matter, merges
and supersedes any prior or contemporaneous agreements or understandings with
respect to its subject matter and shall not be modified or terminated except by
another agreement in writing executed by the Company and Executive.

                  10. SEVERABILITY. If any provision of this Agreement is held
to be invalid or unenforceable by any court or tribunal of competent
jurisdiction, the remainder of this Agreement shall not be affected by such
judgment, and such provision shall be carried out as nearly as possible
according to its original terms and intent to eliminate such invalidity or
un-enforceability.

                  11. SUCCESSORS AND ASSIGNS. Neither party shall have the right
to assign this personal Agreement, or any rights or obligations hereunder,
without the consent of the other party; provided, however, that upon the sale or
transfer of all or substantially all of the assets and business of the Company
to another party, or upon the merger or consolidation of the Company with
another Company, this Agreement shall inure to the benefit of, and be binding
upon, both Executive and the party purchasing or acquiring such assets, business
and goodwill, or surviving such merger or consolidation, as the case may be, in
the same manner and to the same extent as though such other party were the
Company. Subject to the foregoing, this Agreement shall inure to the benefit of,
and bind, the parties hereto and their legal representatives, heirs, successors
and permitted assigns.

                  12. CONSTRUCTION; COUNTERPARTS. The headings contained in this
Agreement are for convenience only and shall in no way restrict or otherwise
affect the construction of the provisions hereof. This Agreement may be executed
in multiple counterparts, each of which shall be an original and all of which
together shall constitute one and the same instrument.

                  13. GOVERNING LAW/DISPUTES. This Agreement shall be governed
by the laws of England applicable to agreements made and fully to be performed
therein by residents thereof. Any dispute arising out of or in connection with
this Agreement, including, without limitation, disputes over the nature of any
termination hereof, shall be finally determined by the British court system.
Each of the parties hereby waives any and all objections he or it may have with
respect to the jurisdiction of such legal forum or the inconvenience of its
venue.

                  IN WITNESS WHEREOF, the parties hereto have duly executed this
Agreement as of the date first set forth above.

holder thereof, in coin or currency, including composite currencies, other than
that in which the Securities are stated to be payable, the period or periods
within which, and the terms and conditions upon which, such election shall be
made;

                  (r) if the amount of payment of principal of and premium, if
any, or interest, if any, on such Securities may be determined with reference to
an index, formula or other method, or based on a coin or currency other than
that in which the Securities are stated to be payable, the manner in which such
amount shall be determined;

                  (s) any addition to, or modification or deletion of, any
covenants or terms herein, including restrictive covenants or Events of Default
provided for with respect to the Securities of the series;

                  (t) the terms and conditions, if any, pursuant to which the
Securities of the series are secured;

                  (u) whether the Securities of the series will be exchangeable
into other securities and, if so, the terms and conditions upon which such
Securities will be so exchangeable, including whether exchange is mandatory, at
the option of the holder, or at the option of the Company, the exchange price,
the exchange period and any provisions pursuant to which the securities to be
received by the holders of such series of Securities would be subject to
adjustment; and

                                       9

<Page>

                  (v) any other terms of such series not inconsistent with this
Indenture.

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

         If any of the terms of the series are established by action taken
pursuant to a Company Order, a copy of an appropriate record of the applicable
Board Resolution shall be certified by the Secretary or an Assistant Secretary
of the Company and delivered to the Trustee at or prior to the delivery of the
Company Order setting forth the terms of that series.

         SECTION 2.02. FORM OF SECURITY AND TRUSTEE'S CERTIFICATE. The
Securities of any series shall be substantially of the tenor and purport (i) as
set forth in one or more indentures supplemental hereto or as provided in a
Company Order, or (ii) with respect to any Tranche of Securities of a series
subject to Periodic Offering, to the extent permitted by any of the documents
referred to in clause (i) above, in Instructions, or by other procedures
acceptable to the Trustee specified in such Company Order or Orders, 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 or designation and such
legends or endorsements printed, lithographed or engraved thereon as the Company
may deem appropriate and as are not inconsistent with the provisions of this
Indenture, or as may be required to comply with any law or with any rule or
regulation made pursuant thereto or with any rule or regulation of any stock
exchange on which Securities of that series may be listed or of the Depository,
or to conform to usage.

         The Trustee's Certificate of Authentication shall be in substantially
the following form:

         "This is one of the Securities of the series designated in accordance
with, and referred to in, the within-mentioned Indenture.

         Dated:

         BNY Midwest Trust Company, as Trustee

         By:___________________________
               Authorized Signatory"

         SECTION 2.03. DATE AND DENOMINATIONS OF SECURITIES, AND PROVISIONS FOR
PAYMENT OF PRINCIPAL, PREMIUM AND INTEREST. Except as otherwise specified as
contemplated by Section 2.01, the Securities shall be issuable as registered
Securities and in the denominations of $1,000 or any integral multiple thereof.
The Securities of a particular series shall bear interest payable on the dates
and at the rate or rates specified with respect to that series. Except as
otherwise specified as contemplated by Section 2.01, the principal of and the
interest on the Securities of any series, as well as any premium thereon in case
of redemption thereof prior to maturity, shall be payable in Dollars at the
office or agency of the Company maintained for that purpose. Each Security shall
be dated the date of its authentication.

                                       10

<Page>

         The interest installment on any Security which is payable, and is
punctually paid or duly provided for, on any Interest Payment Date for
Securities of that series shall be paid to the person in whose name said
Security (or one or more Predecessor Securities) is registered at the close of
business on the regular record date for such interest installment, except that
interest payable on redemption or maturity shall be payable as set forth in the
Company Order or indenture supplemental hereto establishing the terms of such
series of Securities. Except as otherwise specified as contemplated by Section
2.01, interest on Securities will be computed on the basis of a 360-day year of
twelve 30-day months.

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

         (1) The Company may make payment of any Defaulted Interest on
Securities to the persons in whose names such Securities (or their respective
Predecessor Securities) are registered at the close of business on a special
record date for the payment of such Defaulted Interest, which shall be fixed in
the following manner: the Company shall notify the Trustee in writing of the
amount of Defaulted Interest proposed to be paid on each such Security and the
date of the proposed payment, and at the same time the Company shall deposit
with the Trustee an amount of money equal to the aggregate amount proposed to be
paid in respect of such Defaulted Interest or shall make arrangements
satisfactory to the Trustee for such deposit prior to the date of the proposed
payment, such money when deposited to be held in trust for the benefit of the
persons entitled to such Defaulted Interest as in this clause provided.
Thereupon the Trustee shall fix a special record date for the payment of such
Defaulted Interest which shall not be more than 15 nor less than 10 days prior
to the date of the proposed payment and not less than 10 days after the receipt
by the Trustee of the notice of the proposed payment. The Trustee shall promptly
notify the Company of such special record date and, in the name and at the
expense of the Company, shall cause notice of the proposed payment of such
Defaulted Interest and the special record date therefor to be mailed, first
class postage prepaid, to each Securityholder at his or her address as it
appears in the Security Register (as hereinafter defined), not less than 10 days
prior to such special record date. Notice of the proposed payment of such
Defaulted Interest and the special record date therefor having been mailed as
aforesaid, such Defaulted Interest shall be paid to the persons in whose names
such Securities (or their respective Predecessor Securities) are registered on
such special record date and shall be no longer payable pursuant to the
following clause (2).

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

         Unless otherwise set forth in a Company Order or one or more indentures
supplemental hereto establishing the terms of any series of Securities pursuant
to Section 2.01 hereof, the term "regular record date" as used in this Section
with respect to a series of Securities with respect to any Interest Payment Date
for such series shall mean either (i) the fifteenth day of the month or

                                       11

<Page>

the next Business Day immediately preceding the month in which an Interest
Payment Date established for such series pursuant to Section 2.01 hereof shall
occur, if such Interest Payment Date is the first day of a month, or (ii) the
last day of the month or the next Business Day immediately preceding the month
in which an Interest Payment Date established for such series pursuant to
Section 2.01 hereof shall occur, if such Interest Payment Date is the fifteenth
day of a month, whether or not such date is a Business Day.

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

         SECTION 2.04. EXECUTION OF SECURITIES. The Securities shall, subject
to the provisions of Section 2.06, be printed on steel engraved borders or
fully or partially engraved, or legibly typed, as the proper officer of the
Company may determine, and shall be signed on behalf of the Company by an
Authorized Officer. The signature of such Authorized Officer upon the
Securities may be in the form of a facsimile signature of a present or any
future Authorized Officer and may be imprinted or otherwise reproduced on the
Securities and for that purpose the Company may use the facsimile signature
of any person who shall have been an Authorized Officer, notwithstanding the
fact that at the time the Securities shall be authenticated and delivered or
disposed of such person shall have ceased to be an Authorized Officer.

         Only such Securities as shall bear thereon a Certificate of
Authentication substantially in the form established for such Securities,
executed manually by an authorized signatory of the Trustee, or by any
Authenticating Agent with respect to such Securities, shall be entitled to the
benefits of this Indenture or be valid or obligatory for any purpose. Such
certificate executed by the Trustee, or by any Authenticating Agent appointed by
the Trustee with respect to such Securities, upon any Security executed by the
Company shall be conclusive evidence that the Security so authenticated has been
duly authenticated and delivered hereunder and that the registered holder
thereof is entitled to the benefits of this Indenture.

         At any time and from time to time after the execution and delivery of
this Indenture, the Company may deliver Securities of any series executed by the
Company to the Trustee for authentication, together with an indenture
supplemental hereto or a Company Order for the authentication and delivery of
such Securities and the Trustee, in accordance with such supplemental indenture
or Company Order, shall authenticate and deliver such Securities; provided,
however, that in the case of Securities offered in a Periodic Offering, the
Trustee shall authenticate and deliver such Securities from time to time in
accordance with Instructions or such other procedures acceptable to the Trustee
as may be specified by or pursuant to such supplemental indenture or Company
Order delivered to the Trustee prior to the time of the first authentication of
Securities of such series.

         In authenticating such Securities and accepting the additional
responsibilities under this Indenture in relation to such Securities, the
Trustee shall receive and (subject to Section 7.01) shall be fully protected in
relying upon, (i) an Opinion of Counsel and/or (ii) an Officers' Certificate,
each stating that the form and terms thereof have been established in conformity
with the provisions of this Indenture; provided, however, that, with respect to
Securities of a series

                                       12
<Page>

subject to a Periodic Offering, the Trustee shall be entitled to receive such
Opinion of Counsel and/or Officers' Certificate only once at or prior to the
time of the first authentication of Securities of such series and that, in such
opinion or certificate, the opinion or certificate described above may state
that when the terms of such Securities, or each Tranche thereof, shall have been
established pursuant to a Company Order or Orders, supplemental indenture or
indentures, Instruction or Instructions or pursuant to such procedures
acceptable to the Trustee, as may be specified by a Company Order, such terms
will have been established in conformity with the provisions of this Indenture.
Each Opinion of Counsel and Officers' Certificate delivered pursuant to this
Section 2.04 shall include all statements prescribed in Section 13.06(b). Such
Opinion of Counsel shall also be to the effect that when such Securities have
been executed by the Company and authenticated by the Trustee in accordance with
the provisions of this Indenture and delivered to and duly paid for by the
purchasers thereof, they will be valid and legally binding obligations of the
Company, enforceable in accordance with their terms (subject to customary
exceptions) and will be entitled to the benefits of this Indenture.

         With respect to Securities of a series subject to a Periodic Offering,
the Trustee may conclusively rely, as to the authorization by the Company of any
of such Securities, the forms and terms thereof and the legality, validity,
binding effect and enforceability thereof, upon the Company Order, Opinion of
Counsel, Instruction, Officers' Certificate and other documents delivered
pursuant to Sections 2.01 and this Section, as applicable, at or prior to the
time of the first authentication of Securities of such series unless and until
such Company Order, Opinion of Counsel, Instruction, Officers' Certificate or
other documents have been superseded or revoked or expire by their terms.

         The Trustee shall not be required to authenticate such Securities if
the issue of such Securities pursuant to this Indenture will affect the
Trustee's own rights, duties or immunities under the Securities and this
Indenture or otherwise in a manner which is not reasonably acceptable to the
Trustee.

         SECTION 2.05. EXCHANGE OF SECURITIES.

                  (a) REGISTRATION AND TRANSFER OF SECURITIES. Securities of any
series may be exchanged upon presentation thereof at the office or agency of the
Company designated for such purpose, for other Securities of such series of
authorized denominations, and for a like aggregate principal amount, upon
payment of a sum sufficient to cover any tax or other governmental charge in
relation thereto, all as provided in this Section. In respect of any Securities
so surrendered for exchange, the Company shall execute, the Trustee shall
authenticate and such office or agency shall deliver in exchange therefor the
Security or Securities of the same series which the Securityholder making the
exchange shall be entitled to receive, bearing numbers not contemporaneously
outstanding.

                  (b) SECURITY REGISTER; SECURITIES TO BE ACCOMPANIED BY PROPER
INSTRUMENTS OF TRANSFER. The Company shall keep, or cause to be kept, at its
office or agency designated for such purpose in the Borough of Manhattan, the
City and State of New York, or such other location designated by the Company a
register or registers (herein referred to as the "Security Register") in which,
subject to such reasonable regulations as it may prescribe, the Company shall
register the Securities and the transfers of Securities as in this Article
provided and which at

                                       13
<Page>

all reasonable times shall be open for inspection by the Trustee. The registrar
for the purpose of registering Securities and transfer of Securities as herein
provided shall initially be the Trustee or such other person as may be
subsequently appointed as authorized by Board Resolution or Company Order (the
"Security Registrar").

         Upon surrender for transfer of any Security at the office or agency of
the Company designated for such purpose in the Borough of Manhattan, the City
and State of New York, or other location as aforesaid, the Company shall
execute, the Trustee shall authenticate and such office or agency shall deliver
in the name of the transferee or transferees a new Security or Securities of the
same series as the Security presented for a like aggregate principal amount.

         All Securities presented or surrendered for exchange or registration of
transfer, as provided in this Section, shall be accompanied (if so required by
the Company or the Security Registrar) by a written instrument or instruments of
transfer, in form satisfactory to the Company or the Security Registrar, duly
executed by the registered holder or by his duly authorized attorney in writing.

                  (c) CHARGES UPON EXCHANGE, TRANSFER OR REGISTRATION OF
SECURITIES. Except as provided in the first paragraph of Section 2.07, no
service charge shall be made for any exchange or registration of transfer of
Securities, or issue of new Securities in case of partial redemption of any
series, but the Company may require payment of a sum sufficient to cover any tax
or other governmental charge in relation thereto, other than exchanges pursuant
to Section 2.06, Section 3.03(b) and Section 9.04 not involving any transfer.

                  (d) RESTRICTIONS ON TRANSFER OR EXCHANGE AT TIME OF
REDEMPTION. The Company shall neither be required (i) to issue, exchange or
register the transfer of any Securities during a period beginning at the opening
of business 15 days before the day of the mailing of a notice of redemption of
less than all the outstanding Securities of the same series and ending at the
close of business on the day of such mailing, nor (ii) to register the transfer
of or exchange any Securities of any series or portions thereof called for
redemption or as to which the holder thereof has exercised its right, if any, to
require the Company to repurchase such Security in whole or in part, except that
portion of such Security not required to be repurchased. The provisions of this
Section 2.05 are, with respect to any Global Security, subject to Section 2.11
hereof.

         SECTION 2.06. TEMPORARY SECURITIES. Pending the preparation of
definitive Securities of any series, the Company may execute, and the Trustee
shall authenticate and deliver, temporary Securities (printed, lithographed or
typewritten) of any authorized denomination, and substantially in the form of
the definitive Securities in lieu of which they are issued, but with such
omissions, insertions and variations as may be appropriate for temporary
Securities, all as may be determined by the Company. Every temporary Security of
any series shall be executed by the Company and be authenticated by the Trustee
upon the same conditions and in substantially the same manner, and with like
effect, as the definitive Securities of such series in accordance with Section
2.04. Without unnecessary delay the Company will execute and will furnish
definitive Securities of such series and thereupon any or all temporary
Securities of such series may be surrendered in exchange therefor (without
charge to the holders thereof), at the office or agency of the Company
designated for the purpose, and the Trustee shall authenticate

                                       14

<Page>

and such office or agency shall deliver in exchange for such temporary
Securities an equal aggregate principal amount of definitive Securities of such
series, unless the Company advises the Trustee to the effect that definitive
Securities need not be executed and furnished until further notice from the
Company. Until so exchanged, the temporary Securities of such series shall be
entitled to the same benefits under this Indenture as definitive Securities of
such series authenticated and delivered hereunder.

         SECTION 2.07. MUTILATED, DESTROYED, LOST OR STOLEN SECURITIES. In case
any temporary or definitive Security shall become mutilated or be destroyed,
lost or stolen, the Company (subject to the next succeeding sentence) shall
execute, and upon its request the Trustee (subject as aforesaid) shall
authenticate and deliver, a new Security of the same series bearing a number not
contemporaneously outstanding, in exchange and substitution for the mutilated
Security, or in lieu of and in substitution for the Security so destroyed, lost
or stolen. In every case the applicant for a substituted Security shall furnish
to the Company and to the Trustee such security or indemnity as may be required
by them to save each of them harmless, and, in every case of destruction, loss
or theft, the applicant shall also furnish to the Company and to the Trustee
evidence to their satisfaction of the destruction, loss or theft of the
applicant's Security and of the ownership thereof. The Trustee may authenticate
any such substituted Security and deliver the same upon the written request or
authorization of any officer of the Company. Upon the issuance of any
substituted Security, the Company may require the payment of a sum sufficient to
cover any tax or other governmental charge that may be imposed in relation
thereto and any other expenses (including the fees and expenses of the Trustee)
connected therewith. In case any Security which has matured or is about to
mature shall become mutilated or be destroyed, lost or stolen, the Company may,
instead of issuing a substitute Security, pay or authorize the payment of the
same (without surrender thereof except in the case of a mutilated Security) if
the applicant for such payment shall furnish to the Company and to the Trustee
such security or indemnity as they may require to save them harmless, and, in
case of destruction, loss or theft, evidence to the satisfaction of the Company
and the Trustee of the destruction, loss or theft of such Security and of the
ownership thereof.

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

         SECTION 2.08. CANCELLATION OF SURRENDERED SECURITIES. All Securities
surrendered for the purpose of payment, redemption, exchange or registration of
transfer, or for credit against a sinking fund, shall, if surrendered to the
Company or any paying agent, be delivered to the Trustee for cancellation, or,
if surrendered to the Trustee, shall be canceled by it, and no Securities shall
be issued in lieu thereof except as expressly required or permitted by any of
the

                                       15

<Page>

provisions of this Indenture. On request of the Company, the Trustee shall
deliver to the Company canceled Securities held by the Trustee. In the absence
of such request the Trustee may dispose of canceled Securities in accordance
with its standard procedures. If the Company shall otherwise acquire any of the
Securities, however, such acquisition shall not operate as a redemption or
satisfaction of the indebtedness represented by such Securities unless and until
the same are delivered to the Trustee for cancellation.

         SECTION 2.09. PROVISIONS OF INDENTURE AND SECURITIES FOR SOLE BENEFIT
OF PARTIES AND SECURITYHOLDERS. Nothing in this Indenture or in the Securities,
express or implied, shall give or be construed to give to any person, firm or
corporation, other than the parties hereto and the holders of the Securities,
any legal or equitable right, remedy or claim under or in respect of this
Indenture, or under any covenant, condition or provision herein contained; all
such covenants, conditions and provisions being for the sole benefit of the
parties hereto and of the holders of the Securities.

         SECTION 2.10. APPOINTMENT OF AUTHENTICATING AGENT. So long as any of
the Securities of any series remain outstanding there may be an Authenticating
Agent for any or all such series of Securities which the Trustee shall have the
right to appoint. Said Authenticating Agent shall be authorized to act on behalf
of the Trustee to authenticate Securities of such series issued upon exchange,
transfer or partial redemption thereof, and Securities so authenticated shall be
entitled to the benefits of this Indenture and shall be valid and obligatory for
all purposes as if authenticated by the Trustee hereunder. All references in
this Indenture to the authentication of Securities by the Trustee shall be
deemed to include authentication by an Authenticating Agent for such series
except for authentication upon original issuance or pursuant to Section 2.07
hereof. Each Authenticating Agent shall be acceptable to the Company and shall
be a corporation which has a combined capital and surplus, as most recently
reported or determined by it, sufficient under the laws of any jurisdiction
under which it is organized or in which it is doing business to conduct a trust
business, and which is otherwise authorized under such laws to conduct such
business and is subject to supervision or examination by Federal or State
authorities. If at any time any Authenticating Agent shall cease to be eligible
in accordance with these provisions it shall resign immediately.

         Any Authenticating Agent may at any time resign by giving written
notice of resignation to the Trustee and to the Company. The Trustee may at any
time (and upon request by the Company shall) terminate the agency of any
Authenticating Agent by giving written notice of termination to such
Authenticating Agent and to the Company. Upon resignation, termination or
cessation of eligibility of any Authenticating Agent, the Trustee may appoint an
eligible successor Authenticating Agent acceptable to the Company. Any successor
Authenticating Agent, upon acceptance of its appointment hereunder, shall become
vested with all the rights, powers and duties of its predecessor hereunder as if
originally named as an Authenticating Agent pursuant hereto. The Company agrees
to pay to each Authenticating Agent from time to time reasonable compensation
for its services under this Section.

         SECTION 2.11. GLOBAL SECURITY.

                  (a) AUTHENTICATION AND DELIVERY; LEGEND. If the Company shall
establish pursuant to Section 2.01 that the Securities of a particular series
are to be issued as a Global

                                       16

<Page>

Security, then the Company shall execute and the Trustee shall, in accordance
with Section 2.04, authenticate and deliver, a Global Security which (i) shall
represent, and shall be denominated in an amount equal to the aggregate
principal amount of, all of the Outstanding Securities of such series, (ii)
shall be registered in the name of the Depository or its nominee, (iii) shall be
authenticated and delivered by the Trustee to the Depository or pursuant to the
Depository's instruction and (iv) shall bear a legend substantially to the
following effect: "Except as otherwise provided in Section 2.11 of the
Indenture, this Security may be transferred, in whole but not in part, only to
another nominee of the Depository or to a successor Depository or to a nominee
of such successor Depository."

                  (b) TRANSFER OF GLOBAL SECURITY. Notwithstanding the
provisions of Section 2.05, the Global Security of a series may be transferred,
in whole but not in part and in the manner provided in Section 2.05, only to
another nominee of the Depository for such series, or to a successor Depository
for such series selected or approved by the Company or to a nominee of such
successor Depository.

                  (c) ISSUANCE OF SECURITIES IN DEFINITIVE FORM. If at any time
the Depository for a series of Securities notifies the Company that it is
unwilling or unable to continue as Depository for such series or if at any time
the Depository for such series shall no longer be registered or in good standing
under the Exchange Act, or other applicable statute or regulation and a
successor Depository for such series is not appointed by the Company within 90
days after the Company receives such notice or becomes aware of such condition,
as the case may be, this Section 2.11 shall no longer be applicable to the
Securities of such series and the Company will execute, and subject to Section
2.05, the Trustee will authenticate and deliver Securities of such series in
definitive registered form without coupons, in authorized denominations, and in
an aggregate principal amount equal to the principal amount of the Global
Security of such series in exchange for such Global Security. In addition, the
Company may at any time determine that the Securities of any series shall no
longer be represented by a Global Security and that the provisions of this
Section 2.11 shall no longer apply to the Securities of such series. In such
event the Company will execute, and subject to Section 2.05, the Trustee, upon
receipt of an Officers' Certificate evidencing such determination by the
Company, will authenticate and deliver Securities of such series in definitive
registered form without coupons, in authorized denominations, and in an
aggregate principal amount equal to the principal amount of the Global Security
of such series in exchange for such Global Security. Upon the exchange of the
Global Security for such Securities in definitive registered form without
coupons, in authorized denominations, the Global Security shall be canceled by
the Trustee. Such Securities in definitive registered form issued in exchange
for the Global Security pursuant to this Section 2.11(c) shall be registered in
such names and in such authorized denominations as the Depository, pursuant to
instructions from its direct or indirect participants or otherwise, shall
instruct the Security Registrar. The Trustee shall deliver such Securities to
the Depository for delivery to the persons in whose names such Securities are so
registered.

         SECTION 2.12. PAYMENT IN PROPER CURRENCY. In the case of the Securities
of any series denominated in any currency other than Dollars or in a composite
currency (the "Required Currency"), except as otherwise specified with respect
to such Securities as contemplated by Section 2.01, the obligation of the
Company to make any payment of the principal thereof, or the premium or interest
thereon, shall not be discharged or satisfied by any tender by the Company,

                                       17

<Page>

or recovery by the Trustee, in any currency other than the Required Currency,
except to the extent that such tender or recovery shall result in the Trustee
timely holding the full amount of the Required Currency then due and payable. If
any such tender or recovery is in a currency other than the Required Currency,
the Trustee may take such actions as it considers appropriate to exchange such
currency for the Required Currency. The costs and risks of any such exchange,
including, without limitation, the risks of delay and exchange rate fluctuation,
shall be borne by the Company, the Company shall remain fully liable for any
shortfall or delinquency in the full amount of Required Currency then due and
payable, and in no circumstances shall the Trustee be liable therefor except in
the case of its negligence or willful misconduct.

         SECTION 2.13. IDENTIFICATION OF SECURITIES. The Company in issuing
Securities may use "CUSIP" numbers (if then generally in use) and, if so used,
the Trustee shall use "CUSIP" numbers in notices of redemption as a convenience
to holders of Securities; provided that any such notice may state that no
representation is made as to the correctness of such numbers either as printed
on the Securities or contained in any notice of redemption and that reliance may
be placed only on the other identification numbers printed on the Securities,
and any such redemption shall not be affected by any defect in or omission of
such numbers. The Company shall promptly notify the Trustee of any change in the
CUSIP numbers.

                                   ARTICLE III
                    REDEMPTION OF SECURITIES AND SINKING FUND
                                   PROVISIONS

         SECTION 3.01. REDEMPTION OF SECURITIES. The Company may redeem the
Securities of any series issued hereunder on and after the dates and in
accordance with the terms established for such series pursuant to Section 2.01
hereof.

         SECTION 3.02. ACTION TO REDEEM SECURITIES.

                  (a) NOTICE OF REDEMPTION. In case the Company shall desire to
exercise such right to redeem all or, as the case may be, a portion of the
Securities of any series in accordance with the right reserved so to do, it
shall give notice of such redemption to holders of the Securities of such series
to be redeemed by mailing, first class postage prepaid, a notice of such
redemption not less than 30 days and not more than 60 days before the date fixed
for redemption of that series to such holders at their last addresses as they
shall appear upon the Security Register. Any notice which is mailed in the
manner herein provided shall be conclusively presumed to have been duly given,
whether or not the registered holder receives the notice. In any case, failure
duly to give such notice to the holder of any Security of any series designated
for redemption in whole or in part, or any defect in the notice, shall not
affect the validity of the proceedings for the redemption of any other
Securities of such series or any other series. In the case of any redemption of
Securities prior to the expiration of any restriction on such redemption or
subject to compliance with certain conditions provided in the terms of such
Securities or elsewhere in this Indenture, the Company shall furnish the Trustee
with an Officers' Certificate evidencing compliance with any such restriction or
condition.

         Unless otherwise so provided as to a particular series of Securities,
if at the time of mailing of any notice of redemption the Company shall not have
deposited with the paying agent

                                       18

<Page>

an amount in cash sufficient to redeem all of the Securities called for
redemption, including accrued interest to the date fixed for redemption, such
notice shall state that it is subject to the receipt of redemption moneys by the
paying agent on or before the date fixed for redemption (unless such redemption
is mandatory) and such notice shall be of no effect unless such moneys are so
received on or before such date.

         Each such notice of redemption shall identify the Securities to be
redeemed (including CUSIP numbers, if any), specify the date fixed for
redemption and the redemption price at which Securities of that series are to be
redeemed, and shall state that payment of the redemption price of such
Securities to be redeemed will be made at the office or agency of the Company,
upon presentation and surrender of such Securities, that interest accrued to the
date fixed for redemption will be paid as specified in said notice, that from
and after said date interest will cease to accrue and that the redemption is for
a sinking fund, if such is the case. If less than all the Securities of a series
are to be redeemed, the notice to the holders of Securities of that series to be
redeemed in whole or in part shall specify the particular Securities to be so
redeemed. In case any Security is to be redeemed in part only, the notice which
relates to such Security shall state the portion of the principal amount thereof
to be redeemed, and shall state that on and after the redemption date, upon
surrender of such Security, a new Security or Securities of such series in
principal amount equal to the unredeemed portion thereof will be issued.

                  (b) NOTICE TO TRUSTEE OF SECURITIES TO BE REDEEMED. If less
than all the Securities of a series are to be redeemed, the Company shall give
the Trustee at least 45 days' notice in advance of the date fixed for redemption
(unless the Trustee shall agree to a shorter period) as to the aggregate
principal amount of Securities of the series to be redeemed, and thereupon the
Trustee shall select, by lot or in such other manner as it shall deem
appropriate and fair in its discretion and which may provide for the selection
of a portion or portions (equal to the smallest denomination of one whole
Security of such series or any integral multiple thereof) of the principal
amount of such Securities of a denomination larger than the smallest
denomination of one whole Security of such series, the Securities to be redeemed
and shall thereafter promptly notify the Company in writing of the numbers of
the Securities to be redeemed, in whole or in part.

         The Company may, if and whenever it shall so elect, by delivery of
instructions signed on its behalf by an Authorized Officer, instruct the Trustee
or any paying agent to call all or any part of the Securities of a particular
series for redemption and to give notice of redemption in the manner set forth
in this Section, such notice to be in the name of the Company or its own name as
the Trustee or such paying agent may deem advisable. In any case in which notice
of redemption is to be given by the Trustee or any such paying agent, the
Company shall deliver or cause to be delivered to, or permit to remain with, the
Trustee or such paying agent, as the case may be, such Security Register,
transfer books or other records, or suitable copies or extracts therefrom,
sufficient to enable the Trustee or such paying agent to give any notice by mail
that may be required under the provisions of this Section.

         SECTION 3.03. PAYMENT OF SECURITIES CALLED FOR REDEMPTION.

                  (a) WHEN SECURITIES CALLED FOR REDEMPTION BECOME DUE AND
PAYABLE. If the giving of notice of redemption shall have been completed as
above provided, the Securities or

                                       19

<Page>

portions of Securities of the series to be redeemed specified in such notice
shall become due and payable on the date and at the place stated in such notice
at the applicable redemption price, together with, subject to the Company Order
or supplemental indenture hereto establishing the terms of such series of
Securities, interest accrued to the date fixed for redemption and interest on
such Securities or portions of Securities shall cease to accrue on and after the
date fixed for redemption, unless the Company shall default in the payment of
such redemption price and accrued interest with respect to any such Security or
portion thereof. On presentation and surrender of such Securities on or after
the date fixed for redemption at the place of payment specified in the notice,
said Securities shall be paid and redeemed at the applicable redemption price
for such series, together with, subject to the Company Order or supplemental
indenture hereto establishing the terms of such series of Securities, interest
accrued thereon to the date fixed for redemption.

                  (b) RECEIPT OF NEW SECURITY UPON PARTIAL PAYMENT. Upon
presentation of any Security of such series which is to be redeemed in part
only, the Company shall execute and the Trustee shall authenticate and the
office or agency where the Security is presented shall deliver to the holder
thereof, at the expense of the Company, a new Security or Securities of the same
series, of authorized denominations in principal amount equal to the unredeemed
portion of the Security so presented.

         SECTION 3.04. SINKING FUND FOR SECURITIES. The provisions of this
Section 3.04 and Sections 3.05 and 3.06 shall be applicable to any sinking fund
for the retirement of Securities of a series, except as otherwise specified as
contemplated by Section 2.01 for Securities of such series.

         The minimum amount of any sinking fund payment provided for by the
terms of Securities of any series is herein referred to as a "mandatory sinking
fund payment", and any payment in excess of such minimum amount provided for by
the terms of Securities of any series is herein referred to as an "optional
sinking fund payment". If provided for by the terms of Securities of any series,
the cash amount of any sinking fund payment may be subject to reduction as
provided in Section 3.05. Each sinking fund payment shall be applied to the
redemption of Securities of such series as provided for by the terms of
Securities of such series.

         SECTION 3.05. SATISFACTION OF SINKING FUND PAYMENTS WITH SECURITIES.
The Company (i) may deliver Outstanding Securities of a series (other than any
previously called for redemption) and (ii) may apply as a credit Securities of a
series which have been redeemed either at the election of the Company pursuant
to the terms of such Securities or through the application of permitted optional
sinking fund payments pursuant to the terms of such Securities, in each case in
satisfaction of all or any part of any mandatory sinking fund payment; provided
that such Securities have not been previously so credited. Such Securities shall
be received and credited for such purpose by the Trustee at the redemption price
specified in such Securities for redemption through operation of the mandatory
sinking fund and the amount of such mandatory sinking fund payment shall be
reduced accordingly.

         SECTION 3.06. REDEMPTION OF SECURITIES FOR SINKING FUND. Not less than
45 days prior to each sinking fund payment date for any series of Securities,
the Company will deliver to the Trustee an Officers' Certificate specifying the
amount of the next ensuing sinking fund payment

                                       20
<Page>

for that series pursuant to the terms of that series, the portion thereof, if
any, which is to be satisfied by delivering and crediting Securities of that
series pursuant to Section 3.05 and the basis for such credit and will, together
with such Officers' Certificate, deliver to the Trustee any Securities to be so
delivered. Not less than 30 days before each such sinking fund payment date the
Trustee shall select the Securities to be redeemed upon such sinking fund
payment date in the manner specified in Section 3.02 and cause notice of the
redemption thereof to be given in the name of and at the expense of the Company
in the manner provided in Section 3.02, except that the notice of redemption
shall also state that the Securities of such series are being redeemed by
operation of the sinking fund and the sinking fund payment date. Such notice
having been duly given, the redemption of such Securities shall be made upon the
terms and in the manner stated in Section 3.03.

                                   ARTICLE IV
                       PARTICULAR COVENANTS OF THE COMPANY

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

         SECTION 4.01. PAYMENT OF PRINCIPAL (AND PREMIUM IF ANY) AND INTEREST ON
SECURITIES. The Company will duly and punctually pay or cause to be paid the
principal of (and premium, if any) and interest on the Securities of that series
at the time and place and in the manner provided herein and established with
respect to such Securities.

         SECTION 4.02. MAINTENANCE OF OFFICE OR AGENCY FOR PAYMENT,
REGISTRATION, TRANSFER AND EXCHANGE OF SECURITIES. So long as any series of the
Securities remain outstanding, the Company agrees to maintain an office or
agency with respect to each such series, which shall be in the Borough of
Manhattan, the City and State of New York or at such other location or locations
as may be designated as provided in this Section 4.02, where (i) Securities of
that series may be presented for payment, (ii) Securities of that series may be
presented as hereinabove authorized for registration of transfer and exchange,
and (iii) notices and demands to or upon the Company in respect of the
Securities of that series and this Indenture may be given or served, such
designation to continue with respect to such office or agency until the Company
shall, by written notice signed by an Authorized Officer and delivered to the
Trustee, designate some other office or agency for such purposes or any of them.
If at any time the Company shall fail to maintain any such required office or
agency or shall fail to furnish the Trustee with the address thereof, such
presentations, notices and demands may be made or served at the Corporate Trust
Office of the Trustee, and the Company hereby appoints the Trustee as its agent
to receive all such presentations, notices and demands. The Trustee or its agent
will initially act as paying agent for the Securities.

         The Company may also from time to time, by written notice signed by an
Authorized Officer and delivered to the Trustee, designate one or more other
offices or agencies for the foregoing purposes within or outside the Borough of
Manhattan, City of New York, 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 obligations to maintain an office or
agency in the Borough of Manhattan, City of New York for the foregoing purposes.
The Company will give prompt written notice to the Trustee of any change in the
location of any such other office or agency.

                                       21

         SECTION 4.03. PAYING AGENT.

                  (a) DUTIES OF PAYING AGENT. If the Company shall appoint one
or more paying agents for all or any series of the Securities, other than the
Trustee, the Company will cause each such paying agent to execute and deliver to
the Trustee an instrument in which such agent shall agree with the Trustee,
subject to the provisions of this Section:

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

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

                  (3) that it will, at any time during the continuance of any
         failure referred to in the preceding paragraph (a)(2) above, upon the
         written request of the Trustee, forthwith pay to the Trustee all sums
         so held in trust by such paying agent; and

                  (4) that it will perform all other duties of paying agent as
         set forth in this Indenture.

                  (b) COMPANY AS PAYING AGENT. If the Company shall act as its
own paying agent with respect to any series of the Securities, it will on or
before each due date of the principal of (and premium, if any) or interest on
Securities of that series, set aside, segregate and hold in trust for the
benefit of the persons entitled thereto a sum sufficient to pay such principal
(and premium, if any) or interest so becoming due on Securities of that series
until such sums shall be paid to such persons or otherwise disposed of as herein
provided and will promptly notify the Trustee of such action, or any failure (by
it or any other obligor on such Securities) to take such action. Whenever the
Company shall have one or more paying agents for any series of Securities, it
will, prior to each due date of the principal of (and premium, if any) or
interest on any Securities of that series, deposit with the paying agent a sum
sufficient to pay the principal (and premium, if any) or interest so becoming
due, such sum to be held in trust for the benefit of the persons entitled to
such principal, premium or interest, and (unless such paying agent is the
Trustee) the Company will promptly notify the Trustee of its action or failure
so to act.

                  (c) HOLDING SUMS IN TRUST. Anything in this Section to the
contrary notwithstanding, (i) the agreement to hold sums in trust as provided in
this Section is subject to the provisions of Section 11.04, and (ii) the Company
may at any time, for the purpose of obtaining the satisfaction and discharge of
this Indenture or for any other purpose, pay, or direct any paying agent to pay,
to the Trustee all sums held in trust by the Company or such paying agent, such
sums to be held by the Trustee upon the same terms and conditions as those upon
which such sums were held by the Company or such paying agent; and, upon such
payment by any paying agent to the Trustee, such paying agent shall be released
from all further liability with respect to such money.

                                       22

<Page>

         SECTION 4.04. APPOINTMENT TO FILL VACANCY IN OFFICE OF TRUSTEE. The
Company, whenever necessary to avoid or fill a vacancy in the office of Trustee,
will appoint, in the manner provided in Section 7.10, a Trustee, so that there
shall at all times be a Trustee hereunder.

         SECTION 4.05. RESTRICTION ON CONSOLIDATION, MERGER OF TRUSTEE. The
Company will not, while any of the Securities remain outstanding, consolidate
with, or merge into, or merge into itself, or sell or convey all or
substantially all of its property to any other Person unless the provisions of
Article Ten hereof are complied with.

         SECTION 4.06. ORIGINAL ISSUE DISCOUNT SECURITY. In the event that the
Company issues an Original Issue Discount Security, the Company shall file with
the Trustee at or prior to the time of the authentication of such Original Issue
Discount Security a written notice, in such form as mutually agreed upon by the
Company and the Trustee, specifying the amount of original issue discount that
will be accrued on such Original Issue Discount Security in each calendar year
from the date of issuance to the maturity thereof.

                                    ARTICLE V
                    SECURITYHOLDERS' LISTS AND REPORTS BY THE
                             COMPANY AND THE TRUSTEE

         SECTION 5.01. COMPANY TO FURNISH TRUSTEE INFORMATION AS TO NAMES AND
ADDRESSES OF SECURITYHOLDERS. The Company will furnish or cause to be furnished
to the Trustee (a) on each regular record date (as defined in Section 2.03) for
the Securities of each Tranche of a series a list (at intervals of at least
every six months), in such form as the Trustee may reasonably require, of the
names and addresses of the holders of such Tranche of Securities as of such
regular record date, provided, that the Company shall not be obligated to
furnish or cause to be furnished such list at any time that the list shall not
differ in any respect from the most recent list furnished to the Trustee by the
Company and (b) at such other times as the Trustee may request in writing within
30 days after the receipt by the Company of any such request, a list of similar
form and content as of a date not more than 15 days prior to the time such list
is furnished; provided, however, no such list need be furnished for any series
for which the Trustee shall be the Security Registrar.

         SECTION 5.02. RESPONSIBILITIES OF TRUSTEE RELATING TO SECURITYHOLDER
INFORMATION.

                  (a) TRUSTEE TO PRESERVE INFORMATION AS TO NAMES AND ADDRESSES
OF SECURITYHOLDERS. The Trustee shall preserve, in as current a form as is
reasonably practicable, all information as to the names and addresses of the
holders of Securities contained in the most recent list furnished to it as
provided in Section 5.01 and as to the names and addresses of holders of
Securities received by the Trustee in its capacity as Security Registrar (if
acting in such capacity).

                  (b) TRUSTEE MAY DESTROY LIST OF SECURITYHOLDERS ON CERTAIN
CONDITIONS. The Trustee may destroy any list furnished to it as provided in
Section 5.01 upon receipt of a new list so furnished.

                                       23

<Page>

                  (c) TRUSTEE TO MAKE INFORMATION AS TO NAMES AND ADDRESSES OF
SECURITYHOLDERS AVAILABLE TO CERTAIN APPLICANTS. In case three or more holders
of Securities of a series (hereinafter referred to as "applicants") apply in
writing to the Trustee, and furnish to the Trustee reasonable proof that each
such applicant has owned a Security for a period of at least six months
preceding the date of such application, and such application states that the
applicants desire to communicate with other holders of Securities of such series
or holders of all Securities with respect to their rights under this Indenture
or under such Securities, and is accompanied by a copy of the form of proxy or
other communication which such applicants propose to transmit, then the Trustee
shall, within five Business Days after the receipt of such application, at its
election, either:

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

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

                  (d) PROCEDURE IF TRUSTEE ELECTS NOT TO MAKE INFORMATION
AVAILABLE TO APPLICANTS. If the Trustee shall elect not to afford such
applicants access to such information, the Trustee shall, upon the written
request of such applicants, mail to each holder of such series or of all
Securities, as the case may be, whose name and address appears in the
information preserved at the time by the Trustee in accordance with the
provisions of subsection (a) of this Section 5.02, a copy of the form of proxy
or other communication which is specified in such request, with reasonable
promptness after a tender to the Trustee of the material to be mailed and of
payment, or provision for the payment, of the reasonable expenses of mailing,
unless within five days after such tender, the Trustee shall mail to such
applicants and file with the Commission, together with a copy of the material to
be mailed, a written statement to the effect that, in the opinion of the
Trustee, such mailing would be contrary to the best interests of the holders of
Securities of such series or of all Securities, as the case may be, or would be
in violation of applicable law. Such written statement shall specify the basis
of such opinion. If the Commission, after opportunity for a hearing upon the
objections specified in the written statement so filed, shall enter an order
refusing to sustain any of such objections or if, after the entry of an order
sustaining one or more of such objections, the Commission shall find, after
notice and opportunity for hearing, that all the objections so sustained have
been met and shall enter an order so declaring, the Trustee shall mail copies of
such material to all such Securityholders with reasonable promptness after the
entry of such order and the renewal of such tender; otherwise, the Trustee shall
be relieved of any obligation or duty to such applicants respecting their
application.

                  (e) COMPANY AND TRUSTEE NOT ACCOUNTABLE FOR DISCLOSURE OF
INFORMATION. Each and every holder of the Securities, by receiving and holding
the same, agrees with the Company and the Trustee that neither the Company nor
the Trustee nor any paying agent nor any Security Registrar shall be liable
under any law to the extent provided under the Trust Indenture

                                       24

<Page>

Act by reason of the disclosure of any such information as to the names and
addresses of the holders of Securities in accordance with the provisions of
subsection (c) of this Section, regardless of the source from which such
information was derived, and that the Trustee shall not be held accountable by
reason of mailing any material pursuant to a request made under said subsection
(c).

         SECTION 5.03. DELIVERY OBLIGATIONS OF COMPANY.

                  (a) ANNUAL AND OTHER REPORTS TO BE FILED BY COMPANY WITH
TRUSTEE. The Company covenants and agrees to file with the Trustee, within 30
days after the Company is required to file the same with the Commission, a copy
of the annual reports and of the information, documents and other reports (or a
copy of such portions of any of the foregoing as the Commission may from time to
time by rules and regulations prescribe) which the Company may be required to
file with the Commission pursuant to Section 13 or Section 15(d) of the Exchange
Act; or, if the Company is not required to file information, documents or

time to time by the Commission, such of the supplementary and periodic

of the Exchange Act, in respect of a security listed and registered on a
national securities exchange as may be prescribed from time to time in such
rules and regulations.

                  (b) ADDITIONAL INFORMATION AND REPORTS TO BE FILED WITH
TRUSTEE AND SECURITIES AND EXCHANGE COMMISSION. The Company covenants and agrees
to file with the Trustee and the Commission, in accordance with the rules and
regulations prescribed from time to time by the Commission, such additional
information, documents and reports with respect to compliance by the Company
with the conditions and covenants provided for in this Indenture as may be
required from time to time by such rules and regulations.

                  (c) SUMMARIES OF INFORMATION AND REPORTS TO BE TRANSMITTED BY
COMPANY TO SECURITYHOLDERS. The Company covenants and agrees to transmit by
mail, first class postage prepaid, and may also transit by reputable over-night
delivery service which provides for evidence of receipt, to the Securityholders,
as their names and addresses appear upon the Security Register, within 30 days
after the filing thereof with the Trustee, such summaries of any information,
documents and reports required to be filed by the Company pursuant to
subsections (a) and (b) of this Section as may be required by rules and
regulations prescribed from time to time by the Commission.

                  (d) ANNUAL CERTIFICATE TO BE FURNISHED TO TRUSTEE. The Company
covenants and agrees to furnish to the Trustee, on or before May 15 in each
calendar year in which any of the Securities are outstanding, or on or before
such other day in each calendar year as the Company and the Trustee may from
time to time agree upon, a certificate from the principal executive officer,
principal financial officer or principal accounting officer, as to his or her
knowledge, of the Company's compliance with all conditions and covenants under
this Indenture. For purposes of this subsection (d), such compliance shall be
determined without regard to any period of grace or requirement of notice
provided under this Indenture.

                  (e) EFFECT OF DELIVERY TO TRUSTEE. Delivery of such
information, documents or reports to the Trustee pursuant to Section 5.03(a) or
5.03(b) is for informational purposes only and the Trustee's receipt thereof
shall not constitute constructive notice of any information contained therein or
determinable from information contained therein, including, in the case of
Section 5.03(b), the Company's compliance with any of the covenants hereunder.

         SECTION 5.04. DELIVERY OBLIGATIONS OF TRUSTEE.

                  (a) TRUSTEE TO TRANSMIT ANNUAL REPORT TO SECURITYHOLDERS. On
or before May 15 in each year in which any of the Securities are outstanding,
the Trustee shall transmit by mail, first class postage prepaid, to the
Securityholders, as their names and addresses appear upon the Security Register,
a brief report dated as of the preceding May 15, with respect to any of the
following events which may have occurred within the previous twelve months (but
if no such event has occurred within such period no report need be transmitted):

                  (1) any change to its eligibility under Section 7.09, and its
         qualifications under Section 310 of the Trust Indenture Act;

                  (2) the creation of or any material change to a relationship

         Trustee elects so to state, the circumstances surrounding the making
         thereof) made by the Trustee (as such) which remain unpaid on the date
         of such report, and for the reimbursement of which it claims or may
         claim a lien or charge, prior to that of the Securities, on any
         property or funds held or collected by it as trustee if such advances
         so remaining unpaid aggregate more than 1/2 of 1% of the principal
         amount of the Securities outstanding on the date of such report;

                  (4) any change to the amount, interest rate, and maturity date
         of all other indebtedness owing by the Company, or by any other obligor
         on the Securities, to the Trustee in its individual capacity, on the
         date of such report, with a brief description of any property held as
         collateral security therefor, except any indebtedness based upon a
         creditor relationship arising in any manner described in paragraphs
         (2), (3), (4) or (6) of Section 311(b) of the Trust Indenture Act;

                  (5) any change to the property and funds, if any, physically
         in the possession of the Trustee as such on the date of such report;

                  (6) any release, or release and substitution, of property
         subject to the lien, if any, of this Indenture (and the consideration
         therefor, if any) which it has not previously reported;

                  (7) any additional issue of Securities which the Trustee has
         not previously reported; and

                  (8) any action taken by the Trustee in the performance of its
         duties under this Indenture which it has not previously reported and
         which in its opinion materially affects

                                       26
<Page>

         the Securities or the Securities of any series, except any action in
         respect of a default, notice of which has been or is to be withheld
         by it in accordance with the provisions of Section 6.07.

                  (b) TRUSTEE TO TRANSMIT CERTAIN FURTHER REPORTS TO
SECURITYHOLDERS. The Trustee shall transmit by mail, first class postage
prepaid, to the Securityholders, as their names and addresses appear upon the
Security Register, a brief report with respect to the character and amount of
any advances (and if the Trustee elects so to state, the circumstances
surrounding the making thereof) made by the Trustee as such since the date of
the last report transmitted pursuant to the provisions of subsection (a) of this
Section (or if no such report has yet been so transmitted, since the date of
execution of this Indenture), for the reimbursement of which it claims or may
claim a lien or charge prior to that of the Securities of any series on property
or funds held or collected by it as Trustee, and which it has not previously
reported pursuant to this subsection if such advances remaining unpaid at any
time aggregate more than 10% of the principal amount of Securities of such
series outstanding at such time, such report to be transmitted within 90 days
after such time.

                  (c) COPIES OF REPORTS TO BE FILED WITH STOCK EXCHANGES AND
SECURITIES AND EXCHANGE COMMISSION. A copy of each such report shall, at the
time of such transmission to Securityholders, be filed by the Trustee with the
Company, with each stock exchange upon which any Securities are listed (if so
listed) and also with the Commission. The Company agrees to notify the Trustee
when any Securities become listed on any stock exchange or delisted therefrom.

                                   ARTICLE VI
                   REMEDIES OF THE TRUSTEE AND SECURITYHOLDERS
                               ON EVENT OF DEFAULT

         SECTION 6.01. EVENTS OF DEFAULT.

                  (a) EVENTS OF DEFAULT DEFINED. Whenever used herein with
respect to Securities of a particular series, "Event of Default" means any one
or more of the following events which has occurred and is continuing:

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

                  (2) default in the payment of the principal of (or premium, if
         any, on) any of the Securities of that series as and when the same
         shall become due and payable whether at maturity, upon redemption,
         pursuant to any sinking fund obligation, by declaration or otherwise,
         and continuance of such default for a period of three Business Days;

                  (3) failure on the part of the Company duly to observe or
         perform any other of the covenants or agreements on the part of the
         Company with respect to that series contained in such Securities or
         otherwise established with respect to that series of Securities
         pursuant to Section 2.01 hereof or contained in this Indenture (other
         than a

                                       27

<Page>

         covenant or agreement which has been expressly included in this
         Indenture solely for the benefit of one or more series of Securities
         other than such series) for a period of 90 days after the date on which
         written notice of such failure, requiring the same to be remedied and
         stating that such notice is a "Notice of Default" hereunder, shall have
         been given to the Company by the Trustee, by registered or certified
         mail, or to the Company and the Trustee by the holders of at least 33%
         in principal amount of the Securities of that series at the time
         outstanding;

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

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

                  (6) the occurrence of any other Event of Default with respect
         to Securities of such series, as contemplated by Section 2.01 hereof.

                  (b) ACCELERATION OF MATURITY UPON EVENT OF DEFAULT. The
Company shall file with the Trustee written notice of the occurrence of any
Event of Default within five Business Days of the Company's becoming aware of
any such Event of Default. In each and every such case, unless the principal of
all the Securities of that series shall have already become due and payable,
either the Trustee or the holders of not less than 33% in aggregate principal
amount of the Securities of that series then outstanding hereunder, by notice in
writing to the Company (and to the Trustee if given by such Securityholders),
may declare the principal (or, if any of such Securities are Original Issue
Discount Securities, such portion of the principal amount thereof as may be
specified by their terms as contemplated by Section 2.01) of all the Securities
of that series to be due and payable immediately, and upon any such declaration
the same shall become and shall be immediately due and payable, anything
contained in this Indenture or in the Securities of that series or established
with respect to that series pursuant to Section 2.01 hereof to the contrary
notwithstanding.

                                       28

<Page>

                  (c) WAIVER OF DEFAULT AND RESCISSION OF DECLARATION OF
MATURITY. Section 6.01(b), however, is subject to the condition that if, at any
time after the principal of the Securities of that series shall have been so
declared due and payable, and before any judgment or decree for the payment of
the monies due shall have been obtained or entered as hereinafter provided, the
Company shall pay or shall deposit with the Trustee a sum sufficient to pay all
matured installments of interest upon all the Securities of that series and the
principal of (and premium, if any, on) any and all Securities of that series
which shall have become due otherwise than by acceleration (with interest upon
such principal and premium, if any, and, to the extent that such payment is
enforceable under applicable law, upon overdue installments of interest, at the
rate per annum expressed in the Securities of that series to the date of such
payment or deposit) and the amount payable to the Trustee under Section 7.06,
and any and all defaults under the Indenture, other than the nonpayment of
principal on Securities of that series which shall not have become due by their
terms, shall have been remedied or waived as provided in Section 6.06, then and
in every such case the holders of a majority in aggregate principal amount of
the Securities of that series then outstanding, by written notice to the Company
and to the Trustee, may rescind and annul such declaration and its consequences
with respect to that series of Securities; but no such rescission and annulment
shall extend to or shall affect any subsequent default, or shall impair any
right consequent thereon.

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

         SECTION 6.02. RIGHTS OF TRUSTEE UPON DEFAULT.

                  (a) COVENANT OF COMPANY TO PAY TO TRUSTEE WHOLE AMOUNT DUE ON
SECURITIES ON DEFAULT IN PAYMENT OF INTEREST OR PRINCIPAL (AND PREMIUM, IF ANY).
The Company covenants that in case an Event of Default described in subsection
6.01(a)(1) or (a)(2) shall have occurred and be continuing, upon demand of the
Trustee, the Company will pay to the Trustee, for the benefit of the holders of
the Securities of that series, the whole amount that then shall have become due
and payable on all such Securities for principal (and premium, if any) or
interest, or both, as the case may be, with interest upon the overdue principal
(and premium, if any) and (to the extent that payment of such interest is
enforceable under applicable law and without duplication of any other amounts
paid by the Company in respect thereof) upon overdue installments of interest at
the rate per annum expressed in the Securities of that series; and, in addition
thereto, such further amount as shall be sufficient to cover the costs and
expenses of collection, and the amount payable to the Trustee under Section
7.06.

                  (b) TRUSTEE MAY RECOVER JUDGMENT FOR WHOLE AMOUNT DUE ON
SECURITIES ON FAILURE OF COMPANY TO PAY. In case the Company shall fail
forthwith to pay such amounts upon such demand, the Trustee, in its own name and
as trustee of an express trust, shall be entitled and empowered to institute any
action or proceedings at law or in equity for the collection of the sums so due
and unpaid, and may prosecute any such action or proceeding to judgment or final

                                       29

<Page>

decree, and may enforce any such judgment or final decree against the Company or
other obligor upon the Securities of that series and collect in the manner
provided by law out of the property of the Company or other obligor upon the
Securities of that series wherever situated the monies adjudged or decreed to be
payable.

                  (c) PROOF OF CLAIM BY TRUSTEE IN BANKRUPTCY, REORGANIZATION OR
RECEIVERSHIP PROCEEDING. In case of any receivership, insolvency, liquidation,
bankruptcy, reorganization, readjustment, arrangement, composition or other
judicial proceedings affecting the Company, any other obligor on such
Securities, or the creditors or property of either, the Trustee shall have power
to intervene in such proceedings and take any action therein that may be
permitted by the court and shall (except as may be otherwise provided by law) be
entitled to file such proofs of claim and other papers and documents as may be
necessary or advisable in order to have the claims of the Trustee and of the
holders of Securities of such series allowed for the entire amount due and
payable by the Company or such other obligor under this Indenture at the date of
institution of such proceedings and for any additional amount which may become
due and payable by the Company or such other obligor after such date, and to
collect and receive any monies or other property payable or deliverable on any
such claim, and to distribute the same after the deduction of the amount payable
to the Trustee under Section 7.06; and any receiver, assignee or trustee in
bankruptcy or reorganization is hereby authorized by each of the holders of
Securities of such series to make such payments to the Trustee, and, in the
event that the Trustee shall consent to the making of such payments directly to
such Securityholders, to pay to the Trustee any amount due it under Section
7.06.

                  (d) RIGHTS OF ACTION AND OF ASSERTING CLAIMS MAY BE ENFORCED
BY TRUSTEE WITHOUT POSSESSION OF SECURITIES. All rights of action and of
asserting claims under this Indenture, or under any of the terms established
with respect to Securities of that series, may be enforced by the Trustee
without the possession of any of such Securities, or the production thereof at
any trial or other proceeding relative thereto, and any such suit or proceeding
instituted by the Trustee shall be brought in its own name as trustee of an
express trust, and any recovery of judgment shall, after provision for payment
to the Trustee of any amounts due under Section 7.06, be for the ratable benefit
of the holders of the Securities of such series.

         In case of an Event of Default hereunder, the Trustee may in its
discretion proceed to protect and enforce the rights vested in it by this
Indenture by such appropriate judicial proceedings as the Trustee shall deem
most effectual to protect and enforce any of such rights, either at law or in
equity or in bankruptcy or otherwise, whether for the specific enforcement of
any covenant or agreement contained in the Indenture or in aid of the exercise
of any power granted in this Indenture, or to enforce any other legal or
equitable right vested in the Trustee by this Indenture or by law.

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

                                       30

<Page>

         SECTION 6.03. APPLICATION OF MONIES COLLECTED BY TRUSTEE. Any monies
collected by the Trustee pursuant to Section 6.02 with respect to a particular
series of Securities shall be applied in the order following, at the date or
dates fixed by the Trustee and, in case of the distribution of such monies on
account of principal (or premium, if any) or interest, upon presentation of the
several Securities of that series, and stamping thereon the payment, if only
partially paid, and upon surrender thereof if fully paid:

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

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

         THIRD: To the Company.

         SECTION 6.04. LIMITATION ON SUITS BY HOLDERS OF SECURITIES. No holder
of any Security of any series shall have any right by virtue or by availing of
any provision of this Indenture to institute any suit, action or proceeding in
equity or at law upon or under or with respect to this Indenture or for the
appointment of a receiver or trustee, or for any other remedy hereunder, unless
such holder previously shall have given to the Trustee written notice of an
Event of Default and of the continuance thereof with respect to Securities of
such series specifying such Event of Default, as hereinbefore provided, and
unless also the holders of not less than 33% in aggregate principal amount of
the Securities of such series then outstanding shall have made written request
upon the Trustee to institute such action, suit or proceeding in its own name as
trustee hereunder and shall have offered to the Trustee such reasonable
indemnity as it may require against the costs, expenses and liabilities to be
incurred therein or thereby, and the Trustee for 60 days after its receipt of
such notice, request and offer of indemnity, shall have failed to institute any
such action, suit or proceeding; it being understood and intended, and being
expressly covenanted by the taker and holder of every Security of such series
with every other such taker and holder and the Trustee, that no one or more
holders of Securities of such series shall have any right in any manner
whatsoever by virtue or by availing of any provision of this Indenture to
affect, disturb or prejudice the rights of the holders of any other of such
Securities, or to obtain or seek to obtain priority over or preference to any
other such holder, or to enforce any right under this Indenture, except in the
manner herein provided and for the equal, ratable and common benefit of all
holders of Securities of such series. For the protection and enforcement of the
provisions of this Section, each and every Securityholder and the Trustee shall
be entitled to such relief as can be given either at law or in equity.

         Notwithstanding any other provisions of this Indenture, however, the
right of any holder of any Security to receive payment of the principal of (and
premium, if any) and interest on such Security, as therein provided, on or after
the respective due dates expressed in such Security (or in the case of
redemption, on the redemption date), or to institute suit for the enforcement of
any such payment on or after such respective dates or redemption date, shall not
be impaired or affected without the consent of such holder.

                                       31

<Page>

         SECTION 6.05. REMEDIES; DELAY OR OMISSION IN EXERCISE OF RIGHTS.

                  (a) REMEDIES CUMULATIVE. All powers and remedies given by this
Article to the Trustee or to the Securityholders shall, to the extent permitted
by law, be deemed cumulative and not exclusive of any others thereof or of any
other powers and remedies available to the Trustee or the holders of the
Securities, by judicial proceedings or otherwise, to enforce the performance or
observance of the covenants and agreements contained in this Indenture or
otherwise established with respect to such Securities.

                  (b) DELAY OR OMISSION IN EXERCISE OF RIGHTS NOT WAIVER OF
DEFAULT. No delay or omission of the Trustee or of any holder of any of the
Securities to exercise any right or power accruing upon any Event of Default
occurring and continuing as aforesaid shall impair any such right or power, or
shall be construed to be a waiver of any such default or an acquiescence
therein; and, subject to the provisions of Section 6.04, every power and remedy
given by this Article or by law to the Trustee or to the Securityholders may be
exercised from time to time, and as often as shall be deemed expedient, by the
Trustee or by the Securityholders.

         SECTION 6.06. RIGHTS OF HOLDERS OF MAJORITY IN PRINCIPAL AMOUNT OF
SECURITIES TO DIRECT TRUSTEE AND TO WAIVE DEFAULTS. The holders of a majority in
aggregate principal amount of the Securities of any series at the time
outstanding, determined in accordance with Section 8.04, shall have the right to
direct the time, method and place of conducting any proceeding for any remedy
available to the Trustee, or exercising any trust or power conferred on the
Trustee with respect to such series; provided, however, that such direction
shall not be in conflict with any rule of law or with this Indenture or unduly
prejudicial to the rights of holders of Securities of any other series at the
time outstanding determined in accordance with Section 8.04 not parties thereto.
Subject to the provisions of Section 7.01, the Trustee shall have the right to
decline to follow any such direction if the Trustee in good faith shall, by a
Responsible Officer or Officers of the Trustee, determine that the proceeding so
directed might involve the Trustee in personal liability. The holders of a
majority in aggregate principal amount of the Securities of any series at the
time outstanding affected thereby, determined in accordance with Section 8.04,
may on behalf of the holders of all of the Securities of such series waive any
past default in the performance of any of the covenants contained herein or
established pursuant to Section 2.01 with respect to such series and its
consequences, except a default in the payment of the principal of, or premium,
if any, or interest on, any of the Securities of that series as and when the
same shall become due by the terms of such Securities otherwise than by
acceleration (unless such default has been cured and a sum sufficient to pay all
matured installments of interest and principal otherwise than by acceleration
and any premium has been deposited with the Trustee (in accordance with Section
6.01(c))) or a call for redemption of Securities of that series. Upon any such
waiver, the default covered thereby shall be deemed to be cured for all purposes
of this Indenture and the Company, the Trustee and the holders of the Securities
of such series shall be restored to their former positions and rights hereunder,
respectively; but no such waiver shall extend to any subsequent or other default
or impair any right consequent thereon.

         SECTION 6.07. NOTICE OF KNOWN DEFAULTS. The Trustee shall, within 90
days after the occurrence of a default with respect to a particular series,
transmit by mail, first class postage prepaid, to the holders of Securities of
that series, as their names and addresses appear upon the Security Register,
notice of all defaults with respect to that series known to the Trustee, unless

                                       32

<Page>

such defaults shall have been cured or waived before the giving of such notice
(the term "defaults" for the purposes of this Section being hereby defined to be
the events specified in subsections (1), (2), (3), (4), (5), (6) and (7) of
Section 6.01(a), not including any periods of grace provided for therein and
irrespective of the giving of notice provided for by subsection (4) of Section
6.01(a)); provided, that, except in the case of default in the payment of the
principal of (or premium, if any) or interest on any of the Securities of that
series or in the payment of any sinking or analogous fund installment
established with respect to that series, the Trustee shall be protected in
withholding such notice if and so long as the board of directors, the executive
committee, or a trust committee of directors and/or Responsible Officers, of the
Trustee in good faith determine that the withholding of such notice is in the
interests of the holders of Securities of that series; provided further, that in
the case of any default of the character specified in Section 6.01(a)(4) with
respect to Securities of such series no such notice to the holders of the
Securities of that series shall be given until at least 30 days after the
occurrence thereof.

         The Trustee shall not be deemed to have knowledge of any default,
except (i) a default under subsection (a)(1), (a)(2) or (a)(3) of Section 6.01
as long as the Trustee is acting as paying agent for such series of Securities
or (ii) any default as to which the Trustee shall have received written notice
or a Responsible Officer charged with the administration of this Indenture shall
have obtained written notice.

         SECTION 6.08. UNDERTAKING TO PAY COSTS IN CERTAIN SUITS UNDER INDENTURE
OR AGAINST TRUSTEE. All parties to this Indenture agree, and each holder of any
Securities by his or her acceptance thereof shall be deemed to have agreed, that
any court may in its discretion require, in any suit for the enforcement of any
right or remedy under this Indenture, or in any suit against the Trustee for any
action taken or omitted by it as Trustee, the filing by any party litigant in
such suit of an undertaking to pay the costs of such suit, and that such court
may in its discretion assess reasonable costs, including reasonable attorneys'
fees and expenses, against any party litigant in such suit, having due regard to
the merits and good faith of the claims or defenses made by such party litigant;
but the provisions of this Section shall not apply to any suit instituted by the
Trustee, to any suit instituted by any Securityholder, or group of
Securityholders, holding more than 10% in aggregate principal amount of the
outstanding Securities of any series, or to any suit instituted by any
Securityholder for the enforcement of the payment of the principal of (or
premium, if any) or interest on any Security of such series, on or after the
respective due dates expressed in such Security or established pursuant to this
Indenture.

                                  ARTICLE VII
                             CONCERNING THE TRUSTEE

         SECTION 7.01. CERTAIN DUTIES AND RESPONSIBILITIES OF TRUSTEE.

                  (a) UPON EVENT OF DEFAULT. The Trustee, prior to the
occurrence of an Event of Default with respect to Securities of a series and
after the curing of all Events of Default with respect to Securities of that
series which may have occurred, shall undertake to perform with respect to
Securities of such series such duties and only such duties as are specifically
set forth in this Indenture, and no implied covenants or obligations shall be
read into this Indenture against the Trustee. In case an Event of Default with
respect to Securities of a series has occurred

                                       33
<Page>

(which has not been cured or waived), the Trustee shall exercise with respect to
Securities of that series such of the rights and powers vested in it by this
Indenture, and use the same degree of care and skill in their exercise, as a
prudent man would exercise or use under the circumstances in the conduct of his
own affairs.

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

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

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

                       (ii) in the absence of bad faith on the part of the
         Trustee, the Trustee may with respect to Securities of such series
         conclusively rely, as to the truth of the statements and the
         correctness of the opinions expressed therein, upon any certificates or
         opinions furnished to the Trustee and conforming to the requirements of
         this Indenture; but in the case of any such certificates or opinions
         which by any provision hereof are specifically required to be furnished
         to the Trustee, the Trustee shall be under a duty to examine the same
         to determine whether or not they conform to the requirements of this
         Indenture (but need not confirm or investigate the accuracy of
         mathematical calculations or other facts stated therein);

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

                  (3) the Trustee shall not be liable with respect to any action
         taken or omitted to be taken by it in good faith in accordance with the
         written direction of the holders of not less than a majority in
         principal amount of the Securities of any series at the time
         outstanding relating to the time, method and place of conducting any
         proceeding for any remedy available to the Trustee, or exercising any
         trust or power conferred upon the Trustee under this Indenture with
         respect to the Securities of that series; and

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

         SECTION 7.02. CERTAIN RIGHTS OF TRUSTEE. Except as otherwise provided
in Section 7.01:

                  (a) TRUSTEE RELIANCE ON DOCUMENTS. The Trustee may
conclusively rely and shall be fully protected in acting or refraining from
acting upon any resolution, certificate, statement, instrument, opinion, report,
notice, request, direction, consent, order, demand, approval, bond, security or
other paper or document believed by it (i) to be genuine and (ii) to have been
signed or presented by the proper party or parties;

                  (b) EVIDENCE PROVIDED FOR CERTAIN INSTRUMENTS. Any request,
direction, order or demand of the Company mentioned herein shall be sufficiently
evidenced by a Board Resolution or an Officers' Certificate (unless other
evidence in respect thereof is specifically prescribed herein);

                  (c) TRUSTEE MAY CONSULT WITH COUNSEL AND ACT ON ADVICE OR
OPINION OF COUNSEL. The Trustee may consult with counsel of its selection and
the advice of such counsel or any Opinion of Counsel shall be full and complete
authorization and protection in respect of any action taken or suffered or
omitted hereunder in good faith and in reliance thereon;

                  (d) TRUSTEE MAY REQUIRE INDEMNITY FROM SECURITYHOLDERS. The
Trustee shall be under no obligation to exercise any of the rights or powers
vested in it by this Indenture at the request, order or direction of any of the
Securityholders, pursuant to the provisions of this Indenture, unless such
Securityholders shall have offered to the Trustee security or indemnity
satisfactory to it against the costs, expenses and liabilities which may be
incurred therein or thereby; nothing herein contained shall, however, relieve
the Trustee of the obligation, upon the occurrence of an Event of Default with
respect to a series of the Securities (which has not been cured or waived) to
exercise with respect to Securities of that series such of the rights and powers
vested in it by this Indenture, and to use the same degree of care and skill in
their exercise, as a prudent man would exercise or use under the circumstances
in the conduct of his own affairs;

                  (e) TRUSTEE NOT LIABLE FOR ACTIONS IN GOOD FAITH BELIEVED TO
BE AUTHORIZED. The Trustee shall not be liable for any action taken or omitted
to be taken by it in good faith and believed by it to be authorized or within
the discretion or rights or powers conferred upon it by this Indenture;

                  (f) TRUSTEE NOT BOUND TO INVESTIGATE FACTS OR MATTERS. The
Trustee shall not be bound to make any investigation into the facts or matters
stated in any resolution, certificate, statement, instrument, opinion, report,
notice, request, consent, direction, order, demand, approval, bond, security, or
other papers or documents, unless requested in writing so to do by the holders
of not less than a majority in principal amount of the outstanding Securities of
the particular series affected thereby (determined as provided in Section 8.04);
provided, however, that if the payment within a reasonable time to the Trustee
of the costs, expenses or liabilities likely to be incurred by it in the making
of such investigation is, in the opinion of the Trustee, not reasonably assured
to the Trustee by the security afforded to it by the terms of this Indenture,
the Trustee may require reasonable indemnity against such costs, expenses or
liabilities as a condition to so proceeding. The reasonable expense of every
such examination shall be paid by

                                       35

<Page>

the Company or, if paid by the Trustee, shall be repaid by the Company upon
demand. Notwithstanding the foregoing, the Trustee, in its direction, may make
such further inquiry or investigation into such facts or matters as it may see
fit. In making any investigation required or authorized by this subparagraph,
the Trustee shall be entitled to examine books, records and premises of the
Company, personally or by agent or attorney at the expense of the Company and
shall incur no liability of any kind by reason of such inquiry or investigation;

                  (g) TRUSTEE MAY PERFORM DUTIES DIRECTLY OR THROUGH AGENTS OR
ATTORNEYS. The Trustee may execute any of the trusts or powers hereunder or
perform any duties hereunder either directly or by or through agents or
attorneys and the Trustee shall not be responsible for any misconduct or
negligence on the part of any agent or attorney appointed with due care by it
hereunder;

                  (h) PERMISSIVE RIGHTS OF TRUSTEE. The permissive right of the
Trustee to do things enumerated in this Indenture shall not be construed as a
duty.

         SECTION 7.03. LIMITATIONS IN LIABILITY OF TRUSTEE.

                  (a) TRUSTEE NOT LIABLE FOR RECITALS IN INDENTURE OR IN
SECURITIES. The recitals contained herein and in the Securities (other than the
Certificate of Authentication on the Securities) shall be taken as the
statements of the Company, and the Trustee assumes no responsibility for the
correctness of the same.

                  (b) NO REPRESENTATIONS BY TRUSTEE AS TO VALIDITY OR INDENTURE
OR OF SECURITIES. The Trustee makes no representations as to the validity or
sufficiency of this Indenture or of the Securities.

                  (c) TRUSTEE NOT ACCOUNTABLE FOR USE OF SECURITIES OR PROCEEDS.
The Trustee shall not be accountable for the use or application by the Company
of any of the Securities or of the proceeds of such Securities, or for the use
or application of any monies paid over by the Trustee in accordance with any
provision of this Indenture or established pursuant to Section 2.01, or for the
use or application of any monies received by any paying agent other than the
Trustee.

         SECTION 7.04. TRUSTEE, PAYING AGENT OR SECURITY REGISTRAR MAY OWN
SECURITIES. The Trustee or any paying agent or Security Registrar, in its
individual or any other capacity, may become the owner or pledgee of Securities
with the same rights it would have if it were not Trustee, paying agent or
Security Registrar.

         SECTION 7.05. MONIES RECEIVED BY TRUSTEE TO BE HELD IN TRUST WITHOUT
INTEREST. Subject to the provisions of Section 11.04, all monies received by the
Trustee shall, until used or applied as herein provided, be held in trust for
the purposes for which they were received, but need not be segregated from other
funds except to the extent required by law. The Trustee shall be under no
liability for interest on any monies received by it hereunder except such as it
may agree in writing with the Company to pay thereon.

         SECTION 7.06. COMPENSATION AND REIMBURSEMENT OF TRUSTEE.

                                       36

<Page>

                  (a) TRUSTEE ENTITLED TO COMPENSATION, REIMBURSEMENT AND
INDEMNITY. The Company covenants and agrees to pay to the Trustee from time to
time, and the Trustee shall be entitled to, reasonable compensation (which shall
not be limited by any provision of law in regard to the compensation of a
trustee of an express trust) for all services rendered by it in the execution of
the trusts hereby created and in the exercise and performance of any of the
powers and duties hereunder of the Trustee, and the Company will pay or
reimburse the Trustee upon its request for all reasonable expenses,
disbursements and advances incurred or made by the Trustee in accordance with
any of the provisions of this Indenture (including the reasonable compensation
and the reasonable expenses and disbursements of its counsel and agents and of
all persons not regularly in its employ) except any such expense, disbursement
or advance as shall be determined to have been caused by its own negligence,
willful misconduct or bad faith. The Company also covenants to indemnify the
Trustee (and its officers, agents, directors and employees) for, and to hold it
harmless against, any loss, liability or expense incurred without negligence,
willful misconduct or bad faith on the part of the Trustee and arising out of or
in connection with the acceptance or administration of this trust, including the
reasonable costs and expenses of defending itself against any claim or liability
in connection with the exercise or performance of any of its powers or duties
hereunder.

                  (b) OBLIGATIONS TO TRUSTEE TO BE SECURED BY LIEN PRIOR TO
SECURITIES. The obligations of the Company under this Section to compensate and
indemnify the Trustee and to pay or reimburse the Trustee for expenses,
disbursements and advances shall constitute additional indebtedness hereunder.
Such additional indebtedness shall be secured by a lien prior to that of the
Securities upon all property and funds held or collected by the Trustee as such,
except funds held in trust for the benefit of the holders of particular
Securities.

                  (c) NATURE OF EXPENSES. Without prejudice to any other rights
available to the Trustee under applicable law, when the Trustee incurs expenses
or renders services in connection with an Event of Default, the expenses
(including reasonable charges and expenses of its counsel) and compensation for
its services are intended to constitute expenses of administration under
applicable federal or state bankruptcy, insolvency or similar law.

                  (d) SURVIVAL OF OBLIGATIONS. The provisions of this Section
7.06 shall survive the satisfaction and discharge of this Indenture or the
appointment of a successor trustee.

         SECTION 7.07. TRUSTEE MAY RELY ON CERTIFICATE OF OFFICERS OF COMPANY.
Except as otherwise provided in Section 7.01, whenever in the administration of
the provisions of this Indenture the Trustee shall deem it necessary or
desirable that a matter be proved or established prior to taking or suffering or
omitting to take any action hereunder, such matter (unless other evidence in
respect thereof be herein specifically prescribed) may, in the absence of bad
faith on the part of the Trustee, be deemed to be conclusively proved and
established by an Officers' Certificate delivered to the Trustee and such
certificate, in the absence of bad faith on the part of the Trustee, shall be
full warrant to the Trustee for any action taken, suffered or omitted to be
taken by it under the provisions of this Indenture upon the faith thereof.

         SECTION 7.08. TRUSTEE MUST ELIMINATE CONFLICT OR RESIGN. If the Trustee
has acquired or shall acquire a conflicting interest within the meaning of the
Trust Indenture Act, the Trustee

                                       37

<Page>

shall either eliminate such interest or resign, to the extent and in the manner
provided by, and subject to the provisions of, the Trust Indenture Act and this
Indenture.

         SECTION 7.09. REQUIREMENTS FOR ELIGIBILITY OF TRUSTEE. There shall at
all times be a Trustee with respect to the Securities issued hereunder which
shall at all times be a corporation organized and doing business under the laws
of the United States of America or any State or Territory thereof or of the
District of Columbia, or a corporation or other person permitted to act as
trustee by the Commission, authorized under such laws to exercise corporate
trust powers, having a combined capital and surplus of at least 50 million
dollars, and subject to supervision or examination by Federal, State,
Territorial, or District of Columbia authority. If such corporation publishes
reports of condition at least annually, pursuant to law or to the requirements
of the aforesaid supervising or examining authority, then for the purposes of
this Section, the combined capital and surplus of such corporation shall be
deemed to be its combined capital and surplus as set forth in its most recent
report of condition so published. The Company may not, nor may any person
directly or indirectly controlling, controlled by, or under common control with
the Company, serve as Trustee. In case at any time the Trustee shall cease to be
eligible in accordance with the provisions of this Section, the Trustee shall
resign immediately in the manner and with the effect specified in Section 7.10.

         SECTION 7.10. TRUSTEE.

                  (a) RESIGNATION OF TRUSTEE AND APPOINTMENT OF SUCCESSOR. The
Trustee or any successor hereafter appointed, may at any time resign with
respect to the Securities of one or more series by giving written notice thereof
to the Company and by transmitting notice of resignation by mail, first class
postage prepaid, to the Securityholders of such series, as their names and
addresses appear upon the Security Register. Upon receiving such notice of
resignation, the Company shall promptly appoint a successor trustee with respect
to Securities of such series by written instrument, in duplicate, executed by
order of the Board of Directors, one copy of which instrument shall be delivered
to the resigning Trustee and one copy to the successor trustee. If no successor
trustee shall have been so appointed and have accepted appointment within 30
days after the mailing of such notice of resignation, the resigning Trustee may
petition at the expense of the Company any court of competent jurisdiction for
the appointment of a successor trustee with respect to Securities of such
series, or any Securityholder of that series who has been a bona fide holder of
a Security or Securities for at least six months may, subject to the provisions
of Section 6.08, on behalf of himself and all others similarly situated,
petition any such court for the appointment of a successor trustee. Such court
may thereupon after such notice, if any, as it may deem proper and prescribe,
appoint a successor trustee.

                  (b) REMOVAL OF TRUSTEE BY COMPANY OR BY COURT ON
SECURITYHOLDERS' APPLICATION. In case at any time any of the following shall
occur:

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

                                       38

<Page>

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

                  (3) the Trustee shall become incapable of acting, or shall be
         adjudged a bankrupt or insolvent, or a receiver of the Trustee or of
         its property shall be appointed, or any public officer shall take
         charge or control of the Trustee or of its property or affairs for the
         purpose of rehabilitation, conservation or liquidation;

then, in any such case, the Company may remove the Trustee with respect to all
Securities and appoint a successor trustee by written instrument, in duplicate,
executed by order of the Board of Directors, one copy of which instrument shall
be delivered to the Trustee so removed and one copy to the successor trustee,
or, subject to the provisions of Section 6.08, unless, with respect to
subsection (b)(1) above, the Trustee's duty to resign is stayed as provided in
Section 310(b) of the Trust Indenture Act, any Securityholder who has been a
bona fide holder of a Security or Securities for at least six months may, on
behalf of himself and all others similarly situated, petition any court of
competent jurisdiction for the removal of the Trustee and the appointment of a
successor trustee. Such court may thereupon after such notice, if any, as it may
deem proper and prescribe, remove the Trustee and appoint a successor trustee.

                  (c) REMOVAL OF TRUSTEE BY HOLDERS OF MAJORITY IN PRINCIPAL
AMOUNT OF SECURITIES. The holders of a majority in aggregate principal amount of
the Securities of any series at the time outstanding may at any time remove the
Trustee with respect to such series and appoint a successor trustee.

                  (d) TIME WHEN RESIGNATION OR REMOVAL OF TRUSTEE EFFECTIVE. Any
resignation or removal of the Trustee and appointment of a successor trustee
with respect to the Securities of a series pursuant to any of the provisions of
this Section shall become effective upon acceptance of appointment by the
successor trustee as provided in Section 7.11.

                  (e) ONE TRUSTEE FOR EACH SERIES. Any successor trustee
appointed pursuant to this Section may be appointed with respect to the
Securities of one or more series or all of such series, and at any time there
shall be only one Trustee with respect to the Securities of any particular
series.

                  (f) REMOVAL OF TRUSTEE BY THE COMPANY. So long as no Event of
Default has occurred and is continuing with respect to the Securities of a
series, the Company may at any time remove the Trustee with respect to such
series and appoint a successor trustee.

         SECTION 7.11. SUCCESSOR TRUSTEE.

                  (a) ACCEPTANCE BY SUCCESSOR TRUSTEE. In case of the
appointment hereunder of a successor trustee with respect to all Securities,
every such successor trustee so appointed shall execute, acknowledge and deliver
to the Company and to the retiring Trustee an instrument accepting such
appointment, and thereupon the resignation or removal of the retiring Trustee
shall become effective and such successor trustee, without any further act, deed
or conveyance, shall become vested with all the rights, powers, trusts and
duties of the retiring Trustee; but, on the request of the Company or the
successor trustee, such retiring Trustee shall, upon payment of

                                       39

<Page>

its charges, execute and deliver an instrument transferring to such successor
trustee all the rights, powers, and trusts of the retiring Trustee and shall
duly assign, transfer and deliver to such successor trustee all property and
money held by such retiring Trustee hereunder, subject to any prior lien
provided for in Section 7.06(b).

                  (b) TRUSTEE WITH RESPECT TO LESS THAN ALL SERIES. In case of
the appointment hereunder of a successor trustee with respect to the Securities
of one or more (but not all) series, the Company, the retiring Trustee and each
successor trustee with respect to the Securities of one or more series shall
execute and deliver an indenture supplemental hereto wherein each successor
trustee shall accept such appointment and which (1) shall contain such
provisions as shall be necessary or desirable to transfer and confirm to, and to
vest in, each successor trustee all the rights, powers, trusts and duties of the
retiring Trustee with respect to the Securities of that or those series to which
the appointment of such successor trustee relates, (2) shall contain such
provisions as shall be deemed necessary or desirable to confirm that all the
rights, powers, trusts and duties of the retiring Trustee with respect to the
Securities of that or those series as to which the retiring Trustee is not
retiring shall continue to be vested in the retiring Trustee, and (3) shall add
to or change any of the provisions of this Indenture as shall be necessary to
provide for or facilitate the administration of the trusts hereunder by more
than one Trustee, it being understood that nothing herein or in such
supplemental indenture shall constitute such Trustees co-trustees of the same
trust, that each such Trustee shall be trustee of a trust or trusts hereunder
separate and apart from any trust or trusts hereunder administered by any other
such Trustee and that no Trustee shall be responsible for any act or failure to
act on the part of any other Trustee hereunder; and upon the execution and
delivery of such supplemental indenture the resignation or removal of the
retiring Trustee shall become effective to the extent provided therein, such
retiring Trustee shall with respect to the Securities of that or those series to
which the appointment of such successor trustee relates have no further
responsibility for the exercise of rights and powers or for the performance of
the duties and obligations vested in the Trustee under this Indenture, and each
such successor trustee, without any further act, deed or conveyance, shall
become vested with all the rights, powers, trusts and duties of the retiring
Trustee with respect to the Securities of that or those series to which the
appointment of such successor trustee relates; but, on request of the Company or
any successor trustee, such retiring Trustee shall duly assign, transfer and
deliver to such successor trustee, to the extent contemplated by such
supplemental indenture, the property and money held by such retiring Trustee
hereunder with respect to the Securities of that or those series to which the
appointment of such successor trustee relates.

                  (c) COMPANY TO CONFIRM TRUSTEE'S RIGHTS. Upon request of any
such successor trustee, the Company shall execute any and all instruments for
more fully and certainly vesting in and confirming to such successor trustee all
such rights, powers and trusts referred to in paragraph (a) or (b) of this
Section, as the case may be.

                  (d) SUCCESSOR TRUSTEE TO BE QUALIFIED. No successor trustee
shall accept its appointment unless at the time of such acceptance such
successor trustee shall be qualified under the Trust Indenture Act and eligible
under this Article.

                  (e) NOTICE OF SUCCESSION. Upon acceptance of appointment by a
successor trustee as provided in this Section, the Company shall transmit notice
of the succession of such

                                       40

<Page>

trustee hereunder by mail, first class postage prepaid, to the Securityholders,
as their names and addresses appear upon the Security Register. If the Company
fails to transmit such notice within ten days after acceptance of appointment by
the successor trustee, the successor trustee shall cause such notice to be
transmitted at the expense of the Company.

         SECTION 7.12. SUCCESSOR TO TRUSTEE BY MERGER, CONSOLIDATION OF
SUCCESSION TO BUSINESS. Any corporation into which the Trustee may be merged or
converted or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which the Trustee shall be a
party, or any corporation succeeding to all or substantially all of the
corporate trust business of the Trustee, shall be the successor of the Trustee
hereunder, provided such corporation shall be qualified under the provisions of
the Trust Indenture Act and eligible under the provisions of Section 7.09,
without the execution or filing of any paper or any further act on the part of
any of the parties hereto, anything herein to the contrary notwithstanding. In
case any Securities shall have been authenticated, but not delivered, by the
Trustee then in office, any successor by merger, conversion or consolidation to
such authenticating Trustee may adopt such authentication and deliver the
Securities so authenticated with the same effect as if such successor Trustee
had itself authenticated such Securities.

         SECTION 7.13. LIMITATIONS ON RIGHTS OF TRUSTEE AS A CREDITOR TO OBTAIN
PAYMENT OF CERTAIN CLAIMS. If and when the Trustee shall become a creditor of
the Company (or any other obligor upon the Securities), the Trustee shall be
subject to the provisions of the Trust Indenture Act regarding collection of
claims against the Company (or any other obligor upon the Securities).

                                  ARTICLE VIII
                         CONCERNING THE SECURITYHOLDERS

         SECTION 8.01. EVIDENCE OF ACTION BY SECURITYHOLDERS. Whenever in this
Indenture it is provided that the holders of a majority or specified percentage
in aggregate principal amount of the Securities of a particular series may take
any action (including the making of any demand or request, the giving of any
notice, consent or waiver or the taking of any other action), the fact that at
the time of taking any such action the holders of such majority or specified
percentage of that series have joined therein may be evidenced by any instrument
or any number of instruments of similar tenor executed by such holders of
Securities of that series in person or by agent or proxy appointed in writing.

         If the Company shall solicit from the Securityholders of any series any
request, demand, authorization, direction, notice, consent, waiver or other
action, the Company may, at its option, as evidenced by an Officers'
Certificate, fix in advance a record date for such series for the determination
of Securityholders entitled to give such request, demand, authorization,
direction, notice, consent, waiver or other action, but the Company shall have
no obligation to do so. If such a record date is fixed, such request, demand,
authorization, direction, notice, consent, waiver or other action may be given
before or after the record date, but only the Securityholders of record at the
close of business on the record date shall be deemed to be Securityholders for
the purposes of determining whether Securityholders of the requisite proportion
of outstanding Securities of that series have authorized or agreed or consented
to such request, demand, authorization, direction, notice, consent, waiver or
other action, and for that purpose the

                                       41

<Page>

outstanding Securities of that series shall be computed as of the record date;
provided that no such authorization, agreement or consent by such
Securityholders on the record date shall be deemed effective unless it shall
become effective pursuant to the provisions of this Indenture not later than six
months after the record date.

         In determining whether the holders of the requisite aggregate principal
amount of Securities of a particular series have concurred in any direction,
consent or waiver under this Indenture, the principal amount of an Original
Issue Discount Security that shall be deemed to be outstanding for such purposes
shall be the amount of the principal thereof that would be due and payable as of
the date of such determination upon a declaration of acceleration of the
maturity thereof pursuant to Section 6.01.

         SECTION 8.02. PROOF OF EXECUTION OF INSTRUMENTS AND OF HOLDING OF
SECURITIES. Subject to the provisions of Section 7.01, proof of the execution of
any instrument by a Securityholder (such proof will not require notarization) or
his agent or proxy and proof of the holding by any person of any of the
Securities shall be sufficient if made in the following manner:

                  (a) The fact and date of the execution by any such person of
any instrument may be proved in any reasonable manner acceptable to the Trustee.

                  (b) The ownership of Securities shall be proved by the
Security Register of such Securities or by a certificate of the Security
Registrar thereof.

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

         SECTION 8.03. WHO MAY BE DEEMED OWNERS OF SECURITIES. Prior to the due
presentment for registration of transfer of any Security, the Company, the
Trustee, any paying agent and any Security Registrar may deem and treat the
person in whose name such Security shall be registered upon the books of the
Company as the absolute owner of such Security (whether or not such Security
shall be overdue and notwithstanding any notice of ownership or writing thereon
made by anyone other than the Security Registrar) for the purpose of receiving
payment of or on account of the principal of and premium, if any, and (subject
to Section 2.03) interest on such Security and for all other purposes; and
neither the Company nor the Trustee nor any paying agent nor any Security
Registrar shall be affected by any notice to the contrary.

         SECTION 8.04. SECURITIES OWNED BY COMPANY OR AFFILIATED PERSONS
DISREGARDED FOR CERTAIN PURPOSES. In determining whether the holders of the
requisite aggregate principal amount of Securities of a particular series have
concurred in any direction, consent or waiver under this Indenture, Securities
of that series which are owned by the Company or any other obligor on the
Securities of that series or by any person directly or indirectly controlling or
controlled by or under common control with the Company or any other obligor on
the Securities of that series shall be disregarded and deemed not to be
outstanding for the purpose of any such determination, except that for the
purpose of determining whether the Trustee shall be protected in relying on any
such direction, consent or waiver, only Securities of such series which the
Trustee actually knows are so owned shall be so disregarded. Securities so owned
which have been pledged in good faith may be regarded as outstanding for the
purposes of this Section, if the

                                       42

<Page>

pledgee shall establish to the satisfaction of the Trustee the pledgee's right
so to act with respect to such Securities and that the pledgee is not a person
directly or indirectly controlling or controlled by or under direct or indirect
common control with the Company or any such other obligor. In case of a dispute
as to such right, any decision by the Trustee taken upon the advice of counsel
shall be full protection to the Trustee.

         SECTION 8.05. INSTRUMENTS EXECUTED BY SECURITYHOLDERS BINDING ON FUTURE
HOLDERS. At any time prior to (but not after) the evidencing to the Trustee, as
provided in Section 8.01, of the taking of any action by the holders of the
majority or percentage in aggregate principal amount of the Securities of a
particular series specified in this Indenture in connection with such action,
any holder of a Security of that series which is shown by the evidence to be
included in the Securities the holders of which have consented to such action
may, by filing written notice with the Trustee, and upon proof of holding as
provided in Section 8.02, revoke such action so far as concerns such Security.
Except as aforesaid any such action taken by the holder of any Security shall be
conclusive and binding upon such holder and upon all future holders and owners
of such Security, and of any Security issued in exchange therefor, on
registration of transfer thereof or in place thereof, irrespective of whether or
not any notation in regard thereto is made upon such Security. Any action taken
by the holders of the majority or percentage in aggregate principal amount of
the Securities of a particular series specified in this Indenture in connection
with such action shall be conclusively binding upon the Company, the Trustee and
the holders of all the Securities of that series.

                             SUPPLEMENTAL INDENTURES

SECURITYHOLDERS. In addition to any supplemental indenture otherwise authorized
by this Indenture, the Company, when authorized by a Board Resolution, and the
Trustee may from time to time and at any time enter into an indenture or

Default with respect to such series permitting the enforcement of all or any of
the several remedies provided in this Indenture as herein set forth; provided,
however, that in respect of any such additional covenant, restriction, condition
or provision such supplemental indenture may provide for a particular period of
grace after default (which period may be shorter or longer than that allowed in
the case of other defaults) or may provide for an immediate enforcement upon
such default or may limit the remedies available to the Trustee upon such
default or may limit the

                                       43

defective or inconsistent with any other provision contained herein or in any
supplemental indenture, or to make such other provisions in regard to matters or
questions arising under this Indenture as shall not be inconsistent with the
provisions of this Indenture and shall not adversely affect the rights of the
holders of the Securities of any series which are outstanding in any material
respect; or

                  (d) to change or eliminate any of the provisions of this
Indenture or to add any new provision to this Indenture; provided, however, that
such change, elimination or addition shall become effective only as to
Securities issued pursuant to or subsequent to such supplemental indenture
except to the extent such change, elimination or addition does not adversely
affect the rights of any Securityholder of Outstanding Securities in any
material respect; or

                  (e) to establish the form or terms of Securities of any series
as permitted by Section 2.01; or

                  (f) to add any additional Events of Default with respect to
all or any series of outstanding Securities; or

                  (g) to add guarantees with respect to debt securities or to
release a guarantor from guarantees in accordance with the terms of the
applicable series of Securities;

                  (h) to secure a series of Securities by conveying, assigning,
pledging or mortgaging property or assets to the Trustee as collateral security
for such series of Securities; or

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

                  (j) to provide for the authentication and delivery of bearer
securities and coupons appertaining thereto representing interest, if any,

consent of, the holders thereof, and for any other matters incidental thereto;
or

                  (k) evidence and provide for the acceptance of appointment
hereunder by a separate or 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 Article Seven; or

                  (l) to change any place or places where (1) the principal of
and premium, if any, and interest, if any, on all or any series of Securities
shall be payable, (2) all or any series of Securities may be surrendered for
registration of transfer, (3) all or any series of Securities may be surrendered
for exchange and (4) notices and demands to or upon the Company in respect of

                                       44

<Page>

all or any series of Securities and this Indenture may be served; provided,
however, that any such place shall be located in New York, New York or be the
principal office of the Company; or

                  (m) to provide for the payment by the Company of additional
amounts in respect of certain taxes imposed on certain holders and for the
treatment of such additional amounts as interest and for all matters incidental

                  (o) to comply with any requirements of the Commission or the
Trust Indenture Act of 1939, as amended.

         Without limiting the generality of the foregoing, if the Trust
Indenture Act as in effect at the date of the execution and delivery of this
Indenture or at any time thereafter shall be amended and

         (x) if any such amendment shall require one or more changes to any
provisions hereof or the inclusion herein of any additional provisions, or shall
by operation of law be deemed to effect such changes or incorporate such
provisions by reference or otherwise, this Indenture shall be deemed to have
been amended so as to conform to such amendment to the Trust Indenture Act, and
the Company and the Trustee may, without the consent of any Securityholders,
enter into a supplemental indenture hereto to effect or evidence such changes or
additional provisions; or

         (y) if any such amendment shall permit one or more changes to, or
the elimination of, any provisions hereof which, at the date of the execution
and delivery hereof or at any time thereafter, are required by the Trust
Indenture Act to be contained herein, this Indenture shall be deemed to have
been amended to effect such changes or elimination, and the Company and the
Trustee may, without the consent of any Securityholders, enter into a
supplemental indenture hereto to effect such changes or elimination; or

         (z) if, by reason of any such amendment, one or more provisions
which, at the date of the execution and delivery hereof or at any time
thereafter, are required by the Trust Indenture Act to be contained herein shall
be deemed to be incorporated herein by reference or otherwise, or otherwise made
applicable hereto, and shall no longer be required to be contained herein, the
Company and the Trustee may, without the consent of any Securityholders, enter
into a supplemental indenture hereto to effect the elimination of such
provisions.

         The Trustee is hereby authorized to join with the Company in the
execution of any such supplemental indenture, and to make any further
appropriate agreements and stipulations which may be therein contained, but the
Trustee shall not be obligated to enter into any such supplemental indenture
which affects the Trustee's own rights, duties or immunities under this
Indenture or otherwise.

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

         SECTION 9.02. SUPPLEMENTAL INDENTURE WITH CONSENT OF SECURITYHOLDERS.
With the consent (evidenced as provided in Section 8.01) of the holders of not
less than a majority in aggregate principal amount of the Securities of each
series affected by such supplemental indenture or indentures at the time
outstanding, the Company, when authorized by a Board Resolution, and the Trustee
may from time to time and at any time enter into an indenture or indentures
supplemental hereto (which shall conform to the provisions of the Trust
Indenture Act as then in effect) for the purpose of adding any provisions to or
changing in any manner or eliminating any of the provisions of this Indenture or
of any supplemental indenture or of modifying in any manner the rights of the
holders of the Securities of such series under this Indenture; provided,
however, that no such supplemental indenture shall (i) extend the fixed maturity
of any Securities of any series, or reduce the principal amount thereof, or
reduce the rate or extend the time of payment of interest thereon, or reduce any
premium payable upon the redemption thereof, or reduce the amount of the
principal of an Original Issue Discount Security that would be due and payable
upon a declaration of acceleration of the maturity thereof pursuant to Section
6.01, without the consent of the holders of each Security then outstanding and
affected, (ii) reduce the aforesaid percentage of Securities, the holders of
which are required to consent to any such supplemental indenture, or reduce the
percentage of Securities, the holders of which are required to waive any default
and its consequences, without the consent of the holder of each Security then
outstanding and affected thereby, or (iii) modify any provision of Section
6.01(c) (except to increase the percentage of principal amount of securities
required to rescind and annul any declaration of amounts due and payable under
the Securities) without the consent of the holders of each Security then
outstanding and affected thereby.

         Upon the request of the Company, accompanied by a Board Resolution
authorizing the execution of any such supplemental indenture, and upon the
filing with the Trustee of evidence of the consent of Securityholders required
to consent thereto as aforesaid, the Trustee shall join with the Company in the
execution of such supplemental indenture unless such supplemental indenture
affects the Trustee's own rights, duties or immunities under this Indenture or
otherwise, in which case the Trustee may in its discretion, but shall not be
obligated to, enter into such supplemental indenture.

         A supplemental indenture that changes or eliminates any covenant or
other provision of this Indenture that has expressly been included solely for
the benefit of one or more particular series of Securities, or that modifies the
rights of holders of Securities of such series with respect to such covenant or
other provision, shall be deemed not to affect the rights under this Indenture
of the holders of Securities of any other series.

         It shall not be necessary for the consent of the Securityholders of any
series affected thereby under this Section to approve the particular form of any
proposed supplemental indenture, but it shall be sufficient if such consent
shall approve the substance thereof.

         Promptly after the execution by the Company and the Trustee of any
supplemental indenture pursuant to the provisions of this Section, the Trustee
shall transmit by mail, first class postage prepaid, a notice, setting forth in
general terms the substance of such supplemental indenture, to the
Securityholders of all series affected thereby as their names and addresses
appear upon the Security Register. Any failure of the Trustee to mail such
notice, or any defect

                                       46

<Page>

therein, shall not, however, in any way impair or affect the validity of any
such supplemental indenture.

         SECTION 9.03. EFFECT OF SUPPLEMENTAL INDENTURES. Upon the execution of
any supplemental indenture pursuant to the provisions of this Article or of
Section 10.01, this Indenture shall, with respect to such series, be and be
deemed to be modified and amended in accordance therewith and the respective
rights, limitations of rights, obligations, duties and immunities under this
Indenture of the Trustee, the Company and the holders of Securities of the
series affected thereby shall thereafter be determined, exercised and enforced
hereunder subject in all respects to such modifications and amendments, and all
the terms and conditions of any such supplemental indenture shall be and be
deemed to be part of the terms and conditions of this Indenture for any and all
purposes.

         SECTION 9.04. SECURITIES MAY BEAR NOTATION OF CHANGES BY SUPPLEMENTAL
INDENTURES. Securities of any series, affected by a supplemental indenture,
authenticated and delivered after the execution of such supplemental indenture
pursuant to the provisions of this Article, Article Two or Article Seven or of
Section 10.01, may bear a notation in form approved by the Company, provided
such form meets the requirements of any exchange upon which such series may be
listed, as to any matter provided for in such supplemental indenture. If the
Company shall so determine, new Securities of that series so modified as to
conform, in the opinion of the Board of Directors, to any modification of this
Indenture contained in any such supplemental indenture may be prepared by the
Company, authenticated by the Trustee and delivered in exchange for the
Securities of that series then outstanding.

         SECTION 9.05. OPINION OF COUNSEL. The Trustee, subject to the
provisions of Section 7.01, shall be entitled to receive, and shall be fully
protected in relying upon, an Opinion of Counsel as conclusive evidence that any
supplemental indenture executed pursuant to this Article is authorized or
permitted by, and conforms to, the terms of this Article and that it is proper
for the Trustee under the provisions of this Article to join in the execution
thereof.

                                   ARTICLE X.
                         CONSOLIDATION, MERGER AND SALE

         SECTION 10.01. CONSOLIDATIONS OR MERGERS OF COMPANY AND SALES OR
CONVEYANCES OF PROPERTY OF COMPANY. Nothing contained in this Indenture or in
any of the Securities shall prevent any consolidation or merger of the Company
with or into any other corporation or corporations (whether or not affiliated
with the Company), or successive consolidations or mergers in which the Company
or its successor or successors shall be a party or parties, or shall prevent any
sale, conveyance, transfer or other disposition of all or substantially all of
the property of the Company or its successor or successors as an entirety, or
substantially as an entirety, to any other corporation (whether or not
affiliated with the Company or its successor or successors) authorized to
acquire and operate the same; provided, however, the Company hereby covenants
and agrees that, upon any such consolidation, merger, sale, conveyance, transfer
or other disposition, the due and punctual payment of the principal of (premium,
if any) and interest on all of the Securities of all series in accordance with
the terms of each series, according to their tenor, and the due and punctual
performance and observance of all the covenants and conditions of this Indenture
with respect to each series or established with respect to such series pursuant
to

                                       47
<Page>

Section 2.01 to be kept or performed by the Company, shall be expressly assumed,
by supplemental indenture (which shall conform to the provisions of the Trust
Indenture Act as then in effect) satisfactory in form to the Trustee executed
and delivered to the Trustee by the entity formed by such consolidation, or into
which the Company shall have been merged, or by the entity which shall have
acquired such property.

         SECTION 10.02. SUCCESSOR TO COMPANY.

                  (a) RIGHTS AND DUTIES OF SUCCESSOR COMPANY. In case of any
such consolidation, merger, sale, conveyance, transfer or other disposition and
upon the assumption by the successor corporation, by supplemental indenture,
executed and delivered to the Trustee and satisfactory in form to the Trustee,
of the due and punctual payment of the principal of and premium, if any, and
interest on all of the Securities of all series outstanding and the due and
punctual performance of all of the covenants and conditions of this Indenture or
established with respect to each series of the Securities pursuant to Section
2.01 to be kept or performed by the Company with respect to each series, such
successor corporation shall succeed to and be substituted for the Company, with
the same effect as if it had been named herein as the party of the first part,
and thereupon (provided, that in the case of a lease, the term of the lease is
at least as long as the longest maturity of any Securities outstanding at such
time) the predecessor corporation shall be relieved of all obligations and
covenants under this Indenture and the Securities. Such successor corporation
thereupon may cause to be signed, and may issue either in its own name or in the
name of the Company or any other predecessor obligor on the Securities, any or
all of the Securities issuable hereunder which theretofore shall not have been
signed by the Company and delivered to the Trustee; and, upon the order of such
successor company, instead of the Company, and subject to all the terms,
conditions and limitations in this Indenture prescribed, the Trustee shall
authenticate and shall deliver any Securities which previously shall have been
signed and delivered by the officers of the predecessor Company to the Trustee
for authentication, and any Securities which such successor corporation
thereafter shall cause to be signed and delivered to the Trustee for that
purpose. All the Securities so issued shall in all respects have the same legal
rank and benefit under this Indenture as the Securities theretofore or
thereafter issued in accordance with the terms of this Indenture as though all
of such Securities had been issued at the date of the execution hereof.

                  (b) APPROPRIATE CHANGES MAY BE MADE IN PHRASEOLOGY AND FORM OF
SECURITIES. In case of any such consolidation, merger, sale, conveyance,
transfer or other disposition such changes in phraseology and form (but not in
substance) may be made in the Securities thereafter to be issued as may be
appropriate.

                  (c) COMPANY MAY CONSOLIDATE OR MERGE INTO ITSELF OR ACQUIRE
PROPERTIES OF OTHER CORPORATIONS. Nothing contained in this Indenture or in any
of the Securities shall prevent the Company from merging into itself or
acquiring by purchase or otherwise all or any part of the property of any other
corporation (whether or not affiliated with the Company).

         SECTION 10.03. OPINION OF COUNSEL. The Trustee, subject to the
provisions of Section 7.01, may receive an Opinion of Counsel as conclusive
evidence that any such consolidation, merger, sale, conveyance, transfer or
other disposition, and any such assumption, comply with the provisions of this
Article.

                    DEFEASANCE AND CONDITIONS TO DEFEASANCE;
                                UNCLAIMED MONIES

         SECTION 11.01. DEFEASANCE AND CONDITIONS TO DEFEASANCE.

                  (a) SECURITIES MAY BE DEFEASED. Securities of a series may be
defeased in accordance with their terms and, unless the Company Order or
supplemental indenture establishing the series otherwise provides, in accordance
with this Article.

                  (b) COVENANT AND LEGAL DEFEASANCE. The Company at any time may
terminate as to a series its obligations, if any, under any restrictive
covenants which may be applicable to a particular series, to the extent provided
for in a Company order or supplemental indenture relating to such series
("covenant defeasance"). The Company at any time may terminate as to a series
all of its obligations for such series under this Indenture ("legal
defeasance"), except that the Company's obligations in Sections 2.05, 2.07,
4.02, 7.06, 7.10 and 11.04 shall survive until the Securities of the series are
no longer outstanding and, thereafter, the Company's obligations in Sections
7.06, 7.10 and 11.04 shall survive. The Company may exercise its legal
defeasance option notwithstanding its prior exercise of its covenant defeasance
option.

                  (c) CONDITIONS FOR DEFEASANCE. The Company shall exercise as
to a series its legal defeasance option or its covenant defeasance option if:

                  (1) The Company irrevocably deposits in trust with the Trustee
         or another trustee (x) money in an amount which shall be sufficient; or
         (y) Eligible Obligations the principal of and the interest on which
         when due, without regard to reinvestment thereof, will provide moneys,
         which, together with the money, if any, deposited or held by the
         Trustee or such other trustee, shall be sufficient; or (z) a
         combination of money and Eligible Obligations which shall be
         sufficient, to pay the principal of and premium, if any, and interest,
         if any, due and to become due on such Securities on or prior to
         maturity;

                  (2) the Company delivers to the Trustee a Certificate to the
         effect that the requirements set forth in clause (1) above have been
         satisfied;

                  (3) immediately after the deposit no Default exists; and

                  (4) the Company delivers to the Trustee an Opinion of Counsel
         to the effect that holders of the series will not recognize income,
         gain or loss for Federal income tax purposes as a result of the
         defeasance but will realize income, gain or loss on the Securities,
         including payments of interest thereon, in the same amounts and in the
         same manner and at the same time as would have been the case if such
         defeasance had not occurred and which, in the case of legal defeasance,
         shall be (x) accompanied by a ruling of the Internal Revenue Service
         issued to the Company or (y) based on a change in law or regulation
         occurring after the date hereof; and

                                       49

<Page>

                  (5) the deposit specified in paragraph (1) above shall not
         result in the Company, the Trustee or the trust created in connection
         with such defeasance being deemed an "investment company" under the
         Investment Company Act of 1940, as amended.

                  (d) EVENT OF DEFAULT FOLLOWING COVENANT DEFEASANCE. In the
event (i) the Company exercises its option to effect a covenant defeasance with
respect to the Securities of any series, (ii) the Securities of that series are
thereafter declared due and payable pursuant to Section 6.01(b) hereof because
of the occurrence of any Event of Default that results from an event, act or
condition which does not arise from any covenant that has been defeased, and
(iii) the amount of money and securities on deposit with the Trustee are not
sufficient to pay amounts due on the Securities of that series at the time of
the acceleration resulting from such Event of Default, the Company shall be
liable for any such deficiency.

                  (e) EFFECT OF DEFEASANCE. Upon the satisfaction of each of the
foregoing conditions, the obligations of the Company under the restrictive
covenants defeased (in the case of covenant defeasance), and all obligations of
the Company except as set forth in paragraph (b) of this Section 11.01 (in the
case of legal defeasance), shall be terminated with respect to such series.

         SECTION 11.02. APPLICATION BY TRUSTEE OF FUNDS DEPOSITED FOR PAYMENT OF
SECURITIES. All monies or Eligible Obligations deposited with the Trustee
pursuant to Section 11.01 shall be held in trust and shall be available for
payment as due, either directly or through any paying agent (including the
Company acting as its own paying agent), to the holders of the particular series
of Securities for the payment or redemption of which such monies or Eligible
Obligations have been deposited with the Trustee.

         SECTION 11.03. REPAYMENT OF MONIES HELD BY PAYING AGENT. In connection
with the satisfaction and discharge of this Indenture all monies or Eligible
Obligations then held by any paying agent under the provisions of this Indenture
shall, upon demand of the Company, be paid to the Trustee and thereupon such
paying agent shall be released from all further liability with respect to such
monies or Eligible Obligations.

         SECTION 11.04. REPAYMENT OF MONIES HELD BY TRUSTEE. Any monies or
Eligible Obligations deposited with any paying agent or the Trustee, or then
held by the Company, in trust for payment of principal of or premium or interest
on the Securities of a particular series that are not applied but remain
unclaimed by the holders of such Securities for at least two years after the
date upon which the principal of (and premium, if any) or interest on such
Securities shall have respectively become due and payable, upon the written
request of the Company and unless otherwise required by mandatory provisions of
applicable escheat or abandoned or unclaimed property law, shall be repaid to
the Company on May 31 of each year or (if then held by the Company) shall be
discharged from such trust; and thereupon the paying agent and the Trustee shall
be released from all further liability with respect to such monies or Eligible
Obligations, and the holder of any of the Securities entitled to receive such
payment shall thereafter, as an unsecured general creditor, look only to the
Company for the payment thereof.

         SECTION 11.05. DELIVERY OF OFFICER'S CERTIFICATE AND OPINION OF
COUNSEL. In connection with any satisfaction and discharge of this Indenture
pursuant to this Article Eleven, the Company shall deliver to the Trustee an
Officers' Certificate and an Opinion of Counsel to the effect that all
conditions precedent in this Indenture provided for relating to such
satisfaction and discharge have been complied with.

         SECTION 12.01. INCORPORATORS, STOCKHOLDERS, OFFICERS AND DIRECTORS OF
COMPANY EXEMPT FROM INDIVIDUAL LIABILITY. No recourse under or upon any
obligation, covenant or agreement of this Indenture, or of any Security, or for
any claim based thereon or otherwise in respect thereof, shall be had against
any incorporator, stockholder, officer or director, past, present or future as
such, of the Company or of any predecessor or successor corporation, either
directly or through the Company or any such predecessor or successor
corporation, whether by virtue of any constitution, statute or rule of law, or
by the enforcement of any assessment or penalty or otherwise; it being expressly
understood that this Indenture and the obligations issued hereunder are solely
corporate obligations, and that no such personal liability whatever shall attach
to, or is or shall be incurred by, the incorporators, stockholders, officers or
directors as such, of the Company or of any predecessor or successor
corporation, or any of them, because of the creation of the indebtedness hereby
authorized, or under or by reason of the obligations, covenants or agreements
contained in this Indenture or in any of the Securities or implied therefrom;

director as such, because of the creation of the indebtedness hereby authorized,
or under or by reason of the obligations, covenants or agreements contained in

expressly waived and released as a condition of, and as a consideration for, the
execution of this Indenture and the issuance of such Securities.
