                  with.

                  SECTION 103. Form of Documents Delivered to Trustee. In any
case where several matters are required to be certified by, or covered by an
opinion of, any specified Person, it is not necessary that all such matters
be certified by, or covered by the opinion of, only one such Person, or that
they be so certified or covered by only one document, but one such Person may
certify or give an opinion with respect to some matters and one or more other
such Persons as to other matters, and any such Person may certify or give an
opinion as to such matters in one or several documents.

                  Any certificate or opinion of an officer of the Company may
be based, insofar as it relates to legal matters, upon an Opinion of Counsel,
or a certificate or representations by counsel, unless such officer knows, or
in the exercise of reasonable care should know, that the opinion, certificate
or representations with respect to the matters upon which his certificate or
opinion is based are erroneous. Any such Opinion of Counsel or certificate or
representations may be based, insofar as it relates to factual matters, upon
a certificate or opinion of, or representations by, an officer or officers of
the Company stating that the information as to such factual matters is in the
possession of the Company, unless such counsel knows, or in the exercise of
reasonable care should know, that the certificate or opinion or
representations with respect to such matters are erroneous.

                  Where any Person is required to make, give or execute two
or more applications, requests, consents, certificates, statements, opinions
or other instruments under this Indenture, they may, but need not, be
consolidated and form one instrument.

                  SECTION 104. Acts of Holders. (a) Any request, demand,
authorization, direction, notice, consent, waiver or other action provided by
this Indenture to be given or taken by Holders of the Outstanding Securities
of all series or one or more series, as the case may be, may be embodied in
and evidenced by one or more instruments of substantially similar tenor
signed by such Holders in person or by agents duly appointed in writing. If
Securities of a series are issuable as Bearer Securities, any request,
demand, authorization, direction, notice, consent, waiver or other action
provided by this Indenture to be given or taken by Holders of Securities of
such series may, alternatively, be embodied in and evidenced by the record of
Holders of Securities of such series voting in favor thereof, either in
person or by proxies duly appointed in writing, at any meeting of Holders of
Securities of such series duly called and held in accordance with the
provisions of Article Fifteen, or a combination of such instruments and any
such record. Except as herein otherwise expressly provided, such action shall
become effective when such instrument or instruments or record or both are
delivered to the Trustee and, where it is hereby expressly required, to the
Company. Such instrument or instruments and any such record (and the action
embodied therein and evidenced thereby) are herein sometimes referred to as
the "Act" of the Holders signing such instrument or instruments or so voting
at any such meeting. Proof of execution of any such instrument or of a
writing appointing any such agent, or of the holding by any Person of a
Security, shall be sufficient for any purpose of this Indenture and
conclusive in favor of the Trustee and the Company and any agent of the
Trustee or the Company, if made in the manner provided in this Section. The
record of any meeting of Holders of Securities shall be proved in the manner
provided in Section 1506.

                  (b) The fact and date of the execution by any Person of any
such instrument or writing may be proved by the affidavit of a witness of
such execution or by a certificate of a notary public or other officer
authorized by law to take acknowledgments of deeds, certifying


                                      19

<Page>

that the individual signing such instrument or writing acknowledged to him
the execution thereof. Where such execution is by a signer acting in a
capacity other than his individual capacity, such certificate or affidavit
shall also constitute sufficient proof of his authority. The fact and date of
the execution of any such instrument or writing, or the authority of the
Person executing the same, may also be proved in any other reasonable manner
which the Trustee deems sufficient.

                  (c) The ownership of Registered Securities shall be proved
by the Security Register. As to any matter relating to beneficial ownership
interests in any Global Security, the appropriate depository's records shall
be dispositive for purposes of this Indenture.

                  (d) The ownership of Bearer Securities may be proved by the
production of such Bearer Securities or by a certificate executed, as
depository, by any trust company, bank, banker or other depository, wherever
situated, if such certificate shall be deemed by the Trustee to be
satisfactory, showing that at the date therein mentioned such Person had on
deposit with such depository, or exhibited to it, the Bearer Securities
therein described; or such facts may be proved by the certificate or
affidavit of the Person holding such Bearer Securities, if such certificate
or affidavit is deemed by the Trustee to be satisfactory. The Trustee and the
Company may assume that such ownership of any Bearer Security continues until
(1) another certificate or affidavit bearing a later date issued in respect
of the same Bearer Security is produced, or (2) such Bearer Security is
produced to the Trustee by some other Person, or (3) such Bearer Security is
surrendered in exchange for a Registered Security, or (4) such Bearer
Security is no longer Outstanding. The ownership of Bearer Securities may
also be proved in any other manner which the Trustee deems sufficient.

                  (e) If the Company shall solicit from the Holders of
Registered Securities any request, demand, authorization, direction, notice,
consent, waiver or other Act, the Company may, at its option, in or pursuant
to a Board Resolution, fix in advance a record date for the determination of
Holders entitled to give such request, demand, authorization, direction,
notice, consent, waiver or other Act, but the Company shall have no
obligation to do so. Notwithstanding TIA Section 316(c), such record date
shall be the record date specified in or pursuant to such Board Resolution,
which shall be a date not earlier than the date 30 days prior to the first
solicitation of Holders generally in connection therewith and not later than
the date such solicitation is completed. If such a record date is fixed, such
request, demand, authorization, direction, notice, consent, waiver or other
Act may be given before or after such record date, but only the Holders of
record at the close of business on such record date shall be deemed to be
Holders for the purposes of determining whether Holders of the requisite
proportion of Outstanding Securities have authorized or agreed or consented
to such request, demand, authorization, direction, notice, consent, waiver or
other Act, and for that purpose the Outstanding Securities shall be computed
as of such record date; provided that no such authorization, agreement or
consent by the Holders on such record date shall be deemed effective unless
it shall become effective pursuant to the provisions of this Indenture not
later than eleven months after the record date.

                  (f) Any request, demand, authorization, direction, notice,
consent, waiver or other Act of the Holder of any Security shall bind every
future Holder of the same Security and the Holder of every Security issued
upon the registration of transfer thereof or in exchange therefor or in lieu
thereof in respect of anything done, omitted or suffered to be done by the


                                      20

<Page>

Trustee, any Security Registrar, any Paying Agent, any Authenticating Agent
or the Company in reliance thereon, whether or not notation of such action is
made upon such Security.

                  SECTION 105. Notices, etc., to Trustee and Company. Any
request, demand, authorization, direction, notice, consent, waiver or Act of
Holders or other document provided or permitted by this Indenture to be made
upon, given or furnished to, or filed with,

                  (1) the Trustee by any Holder or by the Company shall be
                  sufficient for every purpose hereunder if made, given,
                  furnished or filed in writing to or with the Trustee at
                  [__________________________]; or

                  (2) the Company by the Trustee or by any Holder shall be
                  sufficient for every purpose hereunder (unless otherwise
                  herein expressly provided) if in writing and mailed, first
                  class postage prepaid, to the Company addressed to it at
                  the address of its principal office specified in the first
                  paragraph of this Indenture or at any other address
                  previously furnished in writing to the Trustee by the
                  Company, Attention: Chief Financial Officer, or

                  (3) either the Trustee or the Company, by the other party,
                  shall be sufficient for every purpose hereunder if given by
                  facsimile transmission, receipt confirmed by telephone
                  followed by an original copy delivered by guaranteed
                  overnight courier; if to the Trustee at facsimile number
                  [_________________]; and if to the Company at facsimile
                  number (213) 244-0645.

                  SECTION 106. Notice to Holders: Waiver. Where this
Indenture provides for notice of any event to Holders of Registered
Securities by the Company or the Trustee, such notice shall be sufficiently
given (unless otherwise herein expressly provided) if in writing and mailed,
first-class postage prepaid, to each such Holder affected by such event, at
his address as it appears in the Security Register, not later than the latest
date, if any, and not earlier than the earliest date, if any, prescribed for
the giving of such notice. In any case where notice to Holders of Registered
Securities is given by mail, neither the failure to mail such notice, nor any
defect in any notice so mailed, to any particular Holder shall affect the
sufficiency of such notice with respect to other Holders of Registered
Securities or the sufficiency of any notice to Holders of Bearer Securities
given as provided herein. Any notice mailed to a Holder in the manner herein
prescribed shall be conclusively deemed to have been received by such Holder,
whether or not such Holder actually receives such notice.

                  If by reason of the suspension of or irregularities in
regular mail service or by reason of any other cause it shall be
impracticable to give such notice by mail, then such notification to Holders
of Registered Securities as shall be made with the approval of the Trustee
shall constitute a sufficient notification to such Holders for every purpose
hereunder.

                  Except as otherwise expressly provided herein or otherwise
specified with respect to any Securities pursuant to Section 301, where this
Indenture provides for notice to Holders of Bearer Securities of any event,
such notice shall be sufficiently given if published in an Authorized
Newspaper in The City of New York and in such other city or cities as may be
specified in such Securities on a Business Day, such publication to be not
later than the latest date, if any, and not earlier than the earliest date,
if any, prescribed for the giving of such notice.


                                      21

<Page>

Any such notice shall be deemed to have been given on the date of such
publication or, if published more than once, on the date of the first such
publication.

                  If by reason of the suspension of publication of any
Authorized Newspaper or Authorized Newspapers or by reason of any other cause
it shall be impracticable to publish any notice to Holders of Bearer
Securities as provided above, then such notification to Holders of Bearer
Securities as shall be given with the approval of the Trustee shall
constitute sufficient notice to such Holders for every purpose hereunder.
Neither the failure to give notice by publication to any particular Holder of
Bearer Securities as provided above, nor any defect in any notice so
published, shall affect the sufficiency of such notice with respect to other
Holders of Bearer Securities or the sufficiency of any notice to Holders of
Registered Securities given as provided herein.

                  Any request, demand, authorization, direction, notice,
consent or waiver required or permitted under this Indenture shall be in the
English language, except that any published notice may be in an official
language of the country of publication.

                  Where this Indenture provides for notice in any manner,
such notice may be waived in writing by the Person entitled to receive such
notice, either before or after the event, and such waiver shall be the
equivalent of such notice. Waivers of notice by Holders shall be filed with
the Trustee, but such filing shall not be a condition precedent to the
validity of any action taken in reliance upon such waiver.

                  SECTION 107. Counterparts; Effect of Headings and Table of
Contents. This Indenture may be executed in any number of counterparts, each
of which so executed shall be deemed to be an original, but all such
counterparts shall together constitute but one and the same Indenture. The
Article and Section headings herein and the Table of Contents are for
convenience only and shall not affect the construction hereof.

                  SECTION 108. Successors and Assigns. All covenants and
agreements in this Indenture by the Company shall bind its successors and
assigns, whether so expressed or not.

                  SECTION 109. Severability Clause. In case any provision in
this Indenture or in any Security or coupon shall be held invalid, illegal or
unenforceable, the validity, legality and enforceability of the remaining
provisions shall not in any way be affected or impaired thereby.

                  SECTION 110. Benefits of Indenture. Nothing in this
Indenture or in the Securities or coupons, express or implied, shall give to
any Person, other than the parties hereto, any Security Registrar, any Paying
Agent, any Authenticating Agent and their successors hereunder and the
Holders any benefit or any legal or equitable right, remedy or claim under
this Indenture.

                  SECTION 111. Governing Law. This Indenture and the
Securities and coupons shall be governed by and construed in accordance with
the law of ________. This Indenture is subject to the provisions of the TIA
that are required to be part of this Indenture and shall, to the extent
applicable, be governed by such provisions.

                  SECTION 112. Legal Holidays. In any case where any Interest
Payment Date, Redemption Date, Repayment Date, sinking fund payment date,
Stated Maturity or Maturity of


                                      22

<Page>

any Security or the last date on which a Holder has the right to convert or
exchange a Security shall not be a Business Day at any Place of Payment, then
(notwithstanding any other provision of this Indenture or any Security or
coupon other than a provision in the Securities of any series which
specifically states that such provision shall apply in lieu hereof), payment
of interest or principal (and premium or Make-Whole Amount, if any) or
conversion or exchange of such security need not be made at such Place of
Payment on such date, but (except as otherwise provided in the supplemental
indenture with respect to such Security) may be made on the next succeeding
Business Day at such Place of Payment with the same force and effect as if
made on the Interest Payment Date, Redemption Date, Repayment Date or sinking
fund payment date, or at the Stated Maturity or Maturity, or on such last day
for conversion or exchange, provided that no interest shall accrue on the
amount so payable for the period from and after such Interest Payment Date,
Redemption Date, Repayment Date, sinking fund payment date, Stated Maturity
or Maturity, as the case may be.

                  SECTION 113. Immunity of Stockholders, Directors, Officers
and Agents of the Company. No recourse under or upon any obligation, covenant
or agreement contained in this Indenture, or in any Security, or because of
any indebtedness evidenced thereby, shall be had against any past, present or
future stockholder, employee, officer or director, as such, of the Company or
of any successor, either directly or through the Company or any successor,
under any rule of law, statute or constitutional provision or by the
enforcement of any assessment or by any legal or equitable proceeding or
otherwise, all such liability being expressly waived and released by the
acceptance of the Securities by the Holders and as part of the consideration
for the issue of the Securities.

                  SECTION 114. Conflict with Trust Indenture Act. If any
provision hereof limits, qualifies or conflicts with another provision hereof
which is required or deemed to be included in this Indenture by any of the
provisions of the Trust Indenture Act, such required provision shall control.
If any provision of this Indenture modifies or excludes any provision of the
Trust Indenture Act that may be so modified or excluded, the latter provision
shall be deemed to apply to this Indenture as so modified or to be excluded,
as the case may be.

                         ARTICLE TWO - SECURITIES FORMS

                  SECTION 201. Forms of Securities. The Registered
Securities, if any, of each series and the Bearer Securities, if any, of each
series and related coupons shall be substantially in the form of Exhibit A
hereto or in such other form as shall be established in one or more
indentures supplemental hereto or approved from time to time by or pursuant
to a Board Resolution in accordance with Section 301, shall have such
appropriate insertions, omissions, substitutions and other variations as are
required or permitted by this Indenture or any indenture supplemental hereto,
and may have such letters, numbers or other marks of identification or
designation and such legends or endorsements placed 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 the Securities may be listed, or to conform to usage.

                  Unless otherwise specified as contemplated by Section 301,
Bearer Securities shall have interest coupons attached.


                                      23

<Page>

                  The definitive Securities and coupons shall be printed,
lithographed or engraved or produced by any combination of these methods on a
steel engraved border or steel engraved borders or mechanically reproduced on
safety paper or may be produced in any other manner, all as determined by the
officers executing such Securities or coupons, as evidenced by their
execution of such Securities or coupons.

                  SECTION 202. Form of Trustee's Certificate of
Authentication. Subject to Section 611, the Trustee's certificate of
authentication shall be in substantially the following form:

                  This is one of the Securities of the series designated
therein referred to in the within-mentioned Indenture.

                                            [                   ]
                                            as Trustee


Dated: ______________                       By:_______________________________
                                                    Authorized Signatory

                  SECTION 203. Securities Issuable in Global Form. If
Securities of or within a series are issuable in the form of one or more
Global Securities, then, notwithstanding clause (8) of Section 301 and the
provisions of Section 302, any such Global Security or Securities may provide
that it or they shall represent the aggregate amount of all Outstanding
Securities of such series (or such lesser amount as is permitted by the terms
thereof) from time to time endorsed thereon and may also provide that the
aggregate amount of Outstanding Securities of such series represented thereby
may from time to time be increased or decreased to reflect exchanges. Any
endorsement of any Global Security to reflect the amount, or any increase or
decrease in the amount, or changes in the rights of Holders thereof, of
Outstanding Securities represented thereby shall be made by the Trustee in
such manner or by such Person or Persons as shall be specified therein or in
the Company Order to be delivered to the Trustee pursuant to Section 303 or
304. Subject to the provisions of Section 303 and, if applicable, Section
304, the Trustee shall deliver and redeliver any Global Security in permanent
global form in the manner and upon instructions given by the Person or
Persons specified therein or in the applicable Company Order. If a Company
Order pursuant to Section 303 or 304 has been, or simultaneously is,
delivered, any instructions by the Company with respect to endorsement or
delivery or redelivery of a Global Security shall be in writing but need not
comply with Section 102 and need not be accompanied by an Opinion of Counsel.

                  The provisions of the last sentence of Section 303 shall
apply to any Security represented by a Global Security if such Security was
never issued and sold by the Company and the Company delivers to the Trustee
the Global Security together with written instructions (which need not comply
with Section 102 and need not be accompanied by an Opinion of Counsel) with
regard to the reduction in the principal amount of Securities represented
thereby, together with the written statement contemplated by the last
sentence of Section 303.

                  Notwithstanding the provisions of Section 307, unless
otherwise specified as contemplated by Section 301, payment of principal of
and any premium or Make-Whole


                                      24

<Page>

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

                  Notwithstanding the provisions of Section 308 and except as
provided in the preceding paragraph, the Company, the Trustee and any agent
of the Company and the Trustee shall treat as the Holder of such principal
amount of Outstanding Securities represented by a permanent Global Security
(i) in the case of a permanent Global Security in registered form, the Holder
of such permanent Global Security in registered form, or (ii) in the case of
a permanent Global Security in bearer form, Euroclear or Clearstream.

                  Any Global Security authenticated and delivered hereunder
shall bear a legend in substantially the following form:

                  "This Security is a Global Security within the meaning set
forth in the Indenture hereinafter referred to and is registered in the name
of a Depository or a nominee of a Depository. This Security is exchangeable
for Securities registered in the name of a person other than the Depository
or its nominee only in the limited circumstances described in the Indenture,
and may not be transferred except as a whole by the Depository to a nominee
of the Depository or by a nominee of the Depository to the Depository or
another nominee of the Depository or by the Depository or its nominee to a
successor Depository or its nominee."

aggregate principal amount of Securities which may be authenticated and
delivered under this Indenture is unlimited.

                  Securities of the series that may be authenticated and

                  authenticated and delivered upon registration of transfer of,
                  or in exchange for, or in lieu of, other Securities of the
                  series pursuant to Section 304, 305, 306, 906, 1107 or 1305);

                  (3) The price (expressed as a percentage of the principal

                  declaration of acceleration of the maturity thereof, or (if
                  applicable) the portion of the principal amount of such
                  Securities that is convertible into Common Stock or
                  Preferred Stock, or the method by which any such portion
                  shall be determined;

                  will be payable;

                  (6) The rate or rates (which may be fixed or variable), or

                  (7) The date or dates, or the method for determining such
                  date or dates, from which any such interest will accrue,
                  the dates on which any such interest will be payable, the
                  record dates for such interest payment dates, or the method
                  by which such dates shall be determined, the persons to
                  whom such interest shall be payable, and the basis upon
                  which interest shall be calculated if other than that of a
                  360-day year of twelve 30-day months;

                  (8) The place or places where the principal of (and premium
                  or Make-Whole Amount, if any) and interest, if any, on such
                  Securities will be payable, where such Securities may be
                  surrendered for conversion or registration of transfer or
                  exchange and where notices or demands to or upon the

                  currencies or a composite currency or currencies, the
                  manner of determining the equivalent thereof in Dollars for

                  due upon redemption, if any) or interest, if any, on such
                  Securities may be determined with reference to an index,
                  formula or other method (which index, formula or method
                  may, but need not be, based on the yield on or trading

                  or units or composite currency or currencies other than
                  that in which such Securities are denominated or stated to
                  be payable, the period or periods within which, and the

                  such Securities are denominated or stated to be payable and
                  the currency or currencies, currency unit or units or
                  composite currency or currencies in which such Securities
                  are to be so payable;

                  (14) Provisions, if any, granting special rights to the
                  holders of Securities of the series upon the occurrence of
                  such events as may be specified;

                  (15) Any deletions from, modifications of or additions to
                  the Events of Default or covenants of the Company with
                  respect to Securities of the series, whether or not such
                  Events of Default or covenants are consistent with the
                  Events of Default or covenants set forth herein;

                  (16) Whether and under what circumstances the Company will
                  pay any additional amounts on such Securities in respect of
                  any tax, assessment or governmental charge and, if so,

                  Registered Securities, Bearer Securities (with or without

                  Securities of the series are to be issuable initially in
                  temporary global form and whether any Securities of the
                  series are to be issuable in permanent global form with or
                  without coupons and, if so, whether beneficial owners of
                  interests in any such permanent global Security may
                  exchange such interests for Securities of such series and
                  of like tenor of any authorized form and denomination and
                  the circumstances under which any such exchanges may occur,
                  if other than in the manner provided in the Indenture, and,

                  series and any temporary Global Security representing
                  outstanding Securities of the series shall be dated if
                  other than the date of original issuance of the first
                  Security of the series to be issued;

                  (19) The Person to whom any interest on any Registered
                  Security of the series shall be payable, if other than the
                  Person in whose name that Security (or one or more
                  Predecessor Securities) is registered at the close of
                  business on the Regular


                                      27

<Page>

                  Record Date for such interest, the manner in which, or the
                  Person to whom, any interest on any Bearer Security of the
                  series shall be payable, if otherwise than upon
                  presentation and surrender of the coupons appertaining
                  thereto as they severally mature, and the extent to which,
                  or the manner in which, any interest payable on a temporary
                  Global Security on an Interest Payment Date will be paid if
                  other than in the manner provided herein;

                  (20) The applicability, if any, of the defeasance and
                  covenant defeasance provisions of Article Fourteen hereof
                  to the Securities of the series;

                  (21) If the Securities of such series are to be issuable in
                  definitive form (whether upon original issue or upon
                  exchange of a temporary Security of such series) only upon
                  receipt of certain certificates or other documents or
                  satisfaction of other conditions, then the form and/or
                  terms of such certificates, documents or conditions;

                  (22) The obligation, if any, of the Company to permit the
                  conversion of the Securities of such series into Common
                  Stock or Preferred Stock, as the case may be, and the terms
                  and conditions upon which such conversion shall be effected
                  (including, without limitation, the initial conversion
                  price or rate, the conversion period, any adjustment of the
                  applicable conversion price and any requirements relative
                  to the reservation of such shares for purposes of
                  conversion); and

                  (23) Any other terms of the series (which terms shall not
                  be inconsistent with the provisions of this Indenture).

                  All Securities of any one series and the coupons
appertaining to any Bearer Securities of such series shall be substantially
identical except, in the case of Registered Securities, as to denomination
and except as may otherwise be provided in or pursuant to such Board
Resolution (subject to Section 303) and set forth in such Officers'
Certificate or in any such indenture supplemental hereto. All Securities of
any one series need not be issued at the same time and, unless otherwise
provided, a series may be reopened, without the consent of the Holders, for
issuances of additional Securities of such series. If any of the terms of the
Securities of any series are established by action taken pursuant to one or
more Board Resolutions, a copy of an appropriate record of such action(s)
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 Officers'
Certificate setting forth the terms of the Securities of such series.

                  SECTION 302. Denominations. The Securities of each series
shall be issuable in such denominations as shall be specified as contemplated
by Section 301. With respect to Securities of any series denominated in
Dollars, in the absence of any such provisions with respect to the Securities
of any series, the Securities of such series, other than Global Securities
(which may be of any denomination), shall be issuable in denominations of
$1,000 and any integral multiple thereof.

                  SECTION 303. Execution, Authentication, Delivery and
Dating. The Securities and any coupons appertaining thereto shall be executed
on behalf of the Company by its Chairman of the Board, its President or one
of its Vice Presidents, under its corporate seal


                                      28

<Page>

reproduced thereon, and attested by its Secretary or one of its Assistant
Secretaries. The signature of any of these officers on the Securities and
coupons may be manual or facsimile signatures of the present or any future
such authorized officer and may be imprinted or otherwise reproduced on the
Securities.

          Securities or coupons bearing the manual or facsimile signatures of
individuals who were at any time the proper officers of the Company shall
bind the Company, notwithstanding that such individuals or any of them have
ceased to hold such offices prior to the authentication and delivery of such
Securities or did not hold such offices at the date of such Securities or
coupons. At any time and from time to time after the execution and delivery
of this Indenture, the Company may deliver Securities of any series, together
with any coupon appertaining thereto, executed by the Company to the Trustee
for authentication, together with a Company Order for the authentication and
delivery of such Securities, and the Trustee in accordance with the Company
Order shall authenticate and deliver such Securities; provided, however,
that, in connection with its original issuance, no Bearer Security shall be
mailed or otherwise delivered to any location in the United States; and
provided further that, unless otherwise specified with respect to any series
of Securities pursuant to Section 301, a Bearer Security may be delivered in
connection with its original issuance only if the Person entitled to receive
such Bearer Security shall have furnished a certificate to Euroclear or
Clearstream, as the case may be, in the form set forth in Exhibit B-1 to this
Indenture or such other certificate as may be specified with respect to any
series of Securities pursuant to Section 301, dated no earlier than 15 days
prior to the earlier of the date on which such Bearer Security is delivered
and the date on which any temporary Security first becomes exchangeable for
such Bearer Security in accordance with the terms of such temporary Security
and this Indenture. If any Security shall be represented by a permanent
global Bearer Security, then, for purposes of this Section and Section 304,
the notation of a beneficial owner's interest therein upon original issuance
of such Security or upon exchange of a portion of a temporary Global Security
shall be deemed to be delivery in connection with its original issuance of
such beneficial owner's interest in such permanent Global Security. Except as
permitted by Section 306, the Trustee shall not authenticate and deliver any
Bearer Security unless all appurtenant coupons for interest then matured have
been detached and canceled. If all the Securities of any series are not to be
issued at one time and if the Board Resolution or supplemental indenture
establishing such series shall so permit, such Company Order may set forth
procedures acceptable to the Trustee for the issuance of such Securities and
determining the terms of particular Securities of such series, such as
interest rate or formula, maturity date, date of issuance and date from which
interest shall accrue. In authenticating such Securities, and accepting the
additional responsibilities under this Indenture in relation to such
Securities, the Trustee shall be entitled to receive, and (subject to TIA
Section 315(a) through 315(d)) shall be fully protected in relying upon,

                  (i) an Opinion of Counsel stating that

                           (a) the form or forms of such Securities and any
                  coupons have been established in conformity with the
                  provisions of this Indenture;

                           (b) the terms of such Securities and any coupons
                  have been established in conformity with the provisions of
                  this Indenture; and (c) such Securities, together with any
                  coupons appertaining thereto, when completed by appropriate

                                      29

<Page>

                  insertions and executed and delivered by the Company to the
                  Trustee for authentication in accordance with this
                  Indenture, authenticated and delivered by the Trustee in
                  accordance with this Indenture and issued by the Company in
                  the manner and subject to any conditions specified in such
                  Opinion of Counsel, will constitute legal, valid and
                  legally binding obligations of the Company, enforceable in
                  accordance with their terms, subject to applicable
                  bankruptcy, insolvency, fraudulent transfer, reorganization
                  and other similar laws of general applicability relating to
                  or affecting the enforcement of creditors' rights generally
                  and to general equitable principles; and

                  (ii) an Officers' Certificate stating that all conditions
                  precedent provided for in this Indenture relating to the
                  issuance of the Securities have been complied with and
                  that, to the best of the knowledge of the signers of such
                  certificate, that no Event of Default with respect to any
                  of the Securities shall have occurred and be continuing.

If such form or terms have been so established, 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,
obligations or immunities under the Securities and this Indenture or
otherwise in a manner which is not reasonably acceptable to the Trustee.
Notwithstanding the provisions of Section 301 and of the preceding paragraph,
if all the Securities of any series are not to be issued at one time, it
shall not be necessary to deliver an Officers' Certificate otherwise required
pursuant to Section 301 or a Company Order, or an Opinion of Counsel or an
Officers' Certificate otherwise required pursuant to the preceding paragraph
at the time of issuance of each Security of such series, but such order,
opinion and certificates, with appropriate modifications to cover such future
issuances, shall be delivered at or before the time of issuance of the first
Security of such series.

                  Each Registered Security shall be dated the date of its
authentication and each Bearer Security shall be dated as of the date
specified as contemplated by Section 301.

                  No Security or coupon shall be entitled to any benefit
under this Indenture or be valid or obligatory for any purpose unless there
appears on such Security or Security to which such coupon appertains a
certificate of authentication substantially in the form provided for herein
duly executed by the Trustee by manual signature of an authorized signatory,
and such certificate upon any Security shall be conclusive evidence, and the
only evidence, that such Security has been duly authenticated and delivered
hereunder and is entitled to the benefits of this Indenture. Notwithstanding
the foregoing, if any Security (including a Global Security) shall have been
authenticated and delivered hereunder but never issued and sold by the
Company, and the Company shall deliver such Security to the Trustee for
cancellation as provided in Section 309 together with a written statement
(which need not comply with Section 102 and need not be accompanied by an
Opinion of Counsel) stating that such Security has never been issued and sold
by the Company, for all purposes of this Indenture such Security shall be
deemed never to have been authenticated and delivered hereunder and shall
never be entitled to the benefits of this Indenture.

         SECTION 304.  Temporary Securities.


                                      30

<Page>


                  (a) Pending the preparation of definitive Securities of any
                  series, the Company may execute, and upon Company Order the
                  Trustee shall authenticate and deliver, temporary Securities
                  which are printed, lithographed, typewritten, mimeographed or
                  otherwise produced, in any authorized denomination,
                  substantially of the tenor of the definitive Securities in
                  lieu of which they are issued, in registered form, or, if
                  authorized, in bearer form with one or more coupons or without
                  coupons, and with such appropriate insertions, omissions,
                  substitutions and other variations as the officers executing
                  such Securities may determine, as conclusively evidenced by
                  their execution of such Securities. In the case of Securities
                  of any series, such temporary Securities may be in global
                  form. Except in the case of temporary Global Securities (which
                  shall be exchanged as otherwise provided herein or as
                  otherwise provided in or pursuant to a Board Resolution), if
                  temporary Securities of any series are issued, the Company
                  will cause definitive Securities of that series to be prepared
                  without unreasonable delay. After the preparation of
                  definitive Securities of such series, the temporary Securities
                  of such series shall be exchangeable for definitive Securities
                  of such series upon surrender of the temporary Securities of
                  such series at the office or agency of the Company in a Place
                  of Payment for that series, without charge to the Holder. Upon
                  surrender for cancellation of any one or more temporary
                  Securities of any series (accompanied by any non-matured
                  coupons appertaining thereto), the Company shall execute and
                  the Trustee shall authenticate and deliver in exchange
                  therefor a like principal amount of definitive Securities of
                  the same series of authorized denominations; provided,
                  however, that no definitive Bearer Security shall be delivered
                  in exchange for a temporary Registered Security; and provided
                  further that a definitive Bearer Security shall be delivered
                  in exchange for a temporary Bearer Security only in compliance
                  with the conditions set forth in Section 303. Until so
                  exchanged, the temporary Securities of any series shall in all
                  respects be entitled to the same benefits under this Indenture
                  as definitive Securities of such series.

                  (b) Unless otherwise provided in or pursuant to a Board
                  Resolution, the following provisions of this Section 304(b)
                  shall govern the exchange of temporary Securities other than
                  through the facilities of The Depository Trust Company. If any
                  such temporary Security is issued in global form, then such
                  temporary Global Security shall, unless otherwise provided
                  therein, be delivered to the London office of a depository or
                  common depository (the "Common Depository"), for the benefit
                  of Euroclear and Clearstream, for credit to the respective
                  accounts of the beneficial owners of such Securities (or to
                  such other accounts as they may direct).

                  Without unnecessary delay but in any event not later than the
date specified in, or determined pursuant to the terms of, any such temporary
Global Security (the "Exchange Date"), the Company shall deliver to the Trustee
definitive Securities, in aggregate principal amount equal to the principal
amount of such temporary Global Security, executed by the Company. On or after
the Exchange Date, such temporary Global Security shall be surrendered by the
Common Depository to the Trustee, as the Company's agent for such purpose, to be
exchanged, in whole or from time to time in part, for definitive Securities
without charge, and the Trustee shall authenticate and deliver, in exchange for
each portion of such temporary Global Security, an


                                      31
<Page>


equal aggregate principal amount of definitive Securities of the same series of
authorized denominations and of like tenor as the portion of such temporary
Global Security to be exchanged. The definitive Securities to be delivered in
exchange for any such temporary Global Security shall be in bearer form,
registered form, permanent global bearer form or permanent global registered
form, or any combination thereof, as specified as contemplated by Section 301,
and, if any combination thereof is so specified, as requested by the beneficial
owner thereof; provided, however, that, unless otherwise specified in such
temporary Global Security, upon such presentation by the Common Depository, such
temporary Global Security is accompanied by a certificate dated the Exchange
Date or a subsequent date and signed by Euroclear as to the portion of such
temporary Global Security held for its account then to be exchanged and a
certificate dated the Exchange Date or a subsequent date and signed by
Clearstream as to the portion of such temporary Global Security held for its
account then to be exchanged, each in the form set forth in Exhibit A-2 to this
Indenture or in such other form as may be established pursuant to Section 301;
and provided further that definitive Bearer Securities shall be delivered in
exchange for a portion of a temporary Global Security only in compliance with
the requirements of Section 303.

                  Unless otherwise specified in such temporary Global Security,
the interest of a beneficial owner of Securities of a series in a temporary
Global Security shall be exchanged for definitive Securities of the same series
and of like tenor following the Exchange Date when the account holder instructs
Euroclear or Clearstream, as the case may be, to request such exchange on his
behalf and delivers to Euroclear or Clearstream, as the case may be, a
certificate in the form set forth in Exhibit B-1 to this Indenture (or in such
other form as may be established pursuant to Section 301), dated no earlier than
15 days prior to the Exchange Date, copies of which certificate shall be
available from the offices of Euroclear and Clearstream, the Trustee, any
Authenticating Agent appointed for such series of Securities and each Paying
Agent. Unless otherwise specified in such temporary Global Security, any such
exchange shall be made free of charge to the beneficial owners of such temporary
Global Security, except that a Person receiving definitive Securities must bear
the cost of insurance, postage, transportation and the like unless such Person
takes delivery of such definitive Securities in person at the offices of
Euroclear or Clearstream. Definitive Securities in bearer form to be delivered
in exchange for any portion of a temporary Global Security shall be delivered
only outside the United States.

                  Until exchanged in full as hereinabove provided, the temporary
Securities of any series shall in all respects be entitled to the same benefits
under this Indenture as definitive Securities of the same series and of like
tenor authenticated and delivered hereunder, except that, unless otherwise
specified as contemplated by Section 301, interest payable on a temporary Global
Security on an Interest Payment Date for Securities of such series occurring
prior to the applicable Exchange Date shall be payable to Euroclear and
Clearstream on such Interest Payment Date upon delivery by Euroclear and
Clearstream to the Trustee of a certificate or certificates in such form as may
be established pursuant to Section 301, for credit without further interest on
or after such Interest Payment Date to the respective accounts of Persons who
are the beneficial owners of such temporary Global Security on such Interest
Payment Date and who have each delivered to Euroclear or Clearstream, as the
case may be, a certificate dated no earlier than 15 days prior to the Interest
Payment Date occurring prior to such Exchange Date in such form as may be
established pursuant to Section 301. Notwithstanding anything to the contrary
herein contained, the certifications made pursuant to this paragraph shall
satisfy the certification requirements of the preceding two paragraphs of this
Section 304(b) and of the third paragraph


                                      32
<Page>


of Section 303 of this Indenture and the interests of the Persons who are the
beneficial owners of the temporary Global Security with respect to which such
certification was made will be exchanged for definitive Securities of the same
series and of like tenor on the Exchange Date or the date of certification if
such date occurs after the Exchange Date, without further act or deed by such
beneficial owners. Except as otherwise provided in this paragraph, no payments
of principal or interest owing with respect to a beneficial interest in a
temporary Global Security will be made unless and until such interest in such
temporary Global Security shall have been exchanged for an interest in a
definitive Security. Any interest so received by Euroclear and Clearstream and
not paid as herein provided shall be returned to the Trustee prior to the
expiration of two years after such Interest Payment Date in order to be repaid
to the Company.

                  SECTION 305. Registration, Registration of Transfer and
Exchange. The Company shall cause to be kept at the Corporate Trust Office of
the Trustee or in any office or agency of the Company in a Place of Payment a
register for each series of Securities (the registers maintained in such office
or in any such office or agency of the Company in a Place of Payment being
herein sometimes referred to collectively as the "Security Register") in which,
subject to such reasonable regulations as it may prescribe, the Company shall
provide for the registration of Registered Securities and of transfers of
Registered Securities. The Security Register shall be in written form or any
other form capable of being converted into written form within a reasonable
time. The Trustee, at its Corporate Trust Office, is hereby initially appointed
"Security Registrar" for the purpose of registering Registered Securities and
transfers of Registered Securities on such Security Register as herein provided.
In the event that the Trustee shall cease to be Security Registrar, it shall
have the right to examine the Security Register at all reasonable times.

                  Subject to the provisions of this Section 305, upon surrender
for registration of transfer of any Registered Security of any series at any
office or agency of the Company in a Place of Payment for that series, the
Company shall execute, and the Trustee shall authenticate and deliver, in the
name of the designated transferee or transferees, one or more new Registered
Securities of the same series, of any authorized denominations and of a like
aggregate principal amount, bearing a number not contemporaneously outstanding,
and containing identical terms and provisions.

                  Subject to the provisions of this Section 305, at the option
of the Holder, Registered Securities of any series may be exchanged for other
Registered Securities of the same series, of any authorized denomination or
denominations and of a like aggregate principal amount, containing identical
terms and provisions, upon surrender of the Registered Securities to be
exchanged at any such office or agency. Whenever any such Registered Securities
are so surrendered for exchange, the Company shall execute, and the Trustee
shall authenticate and deliver, the Registered Securities which the Holder
making the exchange is entitled to receive. Unless otherwise specified with
respect to any series of Securities as contemplated by Section 301, Bearer
Securities may not be issued in exchange for Registered Securities.

                  If (but only if) permitted by the applicable Board Resolution
and (subject to Section 303) set forth in the applicable Officers' Certificate,
or in any indenture supplemental hereto, delivered as contemplated by Section
301, at the option of the Holder, Bearer Securities of any series may be
exchanged for Registered Securities of the same series of any authorized
denominations and of a like aggregate principal amount and tenor, upon surrender
of the Bearer


                                      33
<Page>


Securities to be exchanged at any such office or agency, with all unmatured
coupons and all matured coupons in default thereto appertaining. If the Holder
of a Bearer Security is unable to produce any such unmatured coupon or coupons
or matured coupon or coupons in default, any such permitted exchange may be
effected if the Bearer Securities are accompanied by payment in funds acceptable
to the Company in an amount equal to the face amount of such missing coupon or
coupons, or the surrender of such missing coupon or coupons may be waived by the
Company and the Trustee if there is furnished to them such security or indemnity
as they may require to save each of them and any Paying Agent harmless. If
thereafter the Holder of such Security shall surrender to any Paying Agent any
such missing coupon in respect of which such a payment shall have been made,
such Holder shall be entitled to receive the amount of such payment; provided,
however, that, except as otherwise provided in Section 1002, interest
represented by coupons shall be payable only upon presentation and surrender of
those coupons at an office or agency located outside the United States.
Notwithstanding the foregoing, in case a Bearer Security of any series is
surrendered at any such office or agency in a permitted exchange for a
Registered Security of the same series and like tenor after the close of
business at such office or agency on (i) any Regular Record Date and before the
opening of business at such office or agency on the relevant Interest Payment
Date, or (ii) any Special Record Date and before the opening of business at such
office or agency on the related proposed date for payment of Defaulted Interest,
such Bearer Security shall be surrendered without the coupon relating to such
Interest Payment Date or proposed date for payment, as the case may be, and
interest or Defaulted Interest, as the case may be, will not be payable on such
Interest Payment Date or proposed date for payment, as the case may be, in
respect of the Registered Security issued in exchange for such Bearer Security,
but will be payable only to the Holder of such coupon when due in accordance
with the provisions of this Indenture. Whenever any Securities are so
surrendered for exchange, the Company shall execute, and the Trustee shall
authenticate and deliver, the Securities which the Holder making the exchange is
entitled to receive.

                  Notwithstanding the foregoing, except as otherwise specified
as contemplated by Section 301, any permanent Global Security shall be
exchangeable only as provided in this paragraph. If the depository for any
permanent Global Security is The Depository Trust Company ("DTC"), then, unless
the terms of such Global Security expressly permit such Global Security to be
exchanged in whole or in part for definitive Securities, a Global Security may
be transferred, in whole but not in part, only to a nominee of DTC, or by a
nominee of DTC to DTC, or to a successor to DTC for such Global Security
selected or approved by the Company or to a nominee of such successor to DTC. If
at any time DTC notifies the Company that it is unwilling or unable to continue
as depository for the applicable Global Security or Securities or if at any time
DTC ceases to be a clearing agency registered under the Securities Exchange Act
of 1934 if so required by applicable law or regulation, the Company shall
appoint a successor depository with respect to such Global Security or
Securities. If (x) a successor depository for such Global Security or Securities
is not appointed by the Company within 90 days after the Company receives such
notice or becomes aware of such unwillingness, inability or ineligibility, (y)
an Event of Default has occurred and is continuing and the beneficial owners
representing a majority in principal amount of the applicable series of
Securities represented by such Global Security or Securities advise DTC to cease
acting as depository for such Global Security or Securities or (z) the Company,
in its sole discretion, determines at any time that all Outstanding Securities
(but not less than all) of any series issued or issuable in the form of one or
more Global Securities shall no longer be represented by such Global Security or
Securities, then the


                                      34
<Page>


Company shall execute, and the Trustee shall authenticate and deliver definitive
Securities of like series, rank, tenor and terms in definitive form in an
aggregate principal amount equal to the principal amount of such Global Security
or Securities. If any beneficial owner of an interest in a permanent global
Security is otherwise entitled to exchange such interest for Securities of such
series and of like tenor and principal amount of another authorized form and
denomination, as specified as contemplated by Section 301 and provided that any
applicable notice provided in the permanent Global Security shall have been
given, then without unnecessary delay but in any event not later than the
earliest date on which such interest may be so exchanged, the Company shall
execute, and the Trustee shall authenticate and deliver definitive Securities
in aggregate principal amount equal to the principal amount of such beneficial
owner's interest in such permanent Global Security. On or after the earliest
date on which such interests may be so exchanged, such permanent Global Security
shall be surrendered for exchange by DTC or such other depository as shall be
specified in the Company Order with respect thereto to the Trustee, as the
Company's agent for such purpose; provided, however, that no such exchanges may
occur during a period beginning at the opening of business 15 days before any
selection of Securities to be redeemed and ending on the relevant Redemption
Date if the Security for which exchange is requested may be among those selected
for redemption; and provided further that no Bearer Security delivered in
exchange for a portion of a permanent Global Security shall be mailed or
otherwise delivered to any location in the United States. If a Registered
Security is issued in exchange for any portion of a permanent Global Security
after the close of business at the office or agency where such exchange occurs
on (i) any Regular Record Date and before the opening of business at such office
or agency on the relevant Interest Payment Date, or (ii) any Special Record Date
and the opening of business at such office or agency on the related proposed
date for payment of Defaulted Interest, interest or Defaulted Interest, as the
case may be, will not be payable on such Interest Payment Date or proposed date
for payment, as the case may be, in respect of such Registered Security, but
will be payable on such Interest Payment Date or proposed date for payment, as
the case may be, only to the Person to whom interest in respect of such portion
of such permanent Global Security is payable in accordance with the provisions
of this Indenture.

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

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

                  No service charge shall be made for any registration of
transfer or exchange of Securities, but the Company may require payment of a sum
sufficient to cover any tax or other governmental charge that may be imposed in
connection with any registration of transfer or exchange of Securities, other
than exchanges pursuant to Section 304, 9.6, 11.7 or 13.5 not involving any
transfer. The Company or the Trustee, as applicable, shall not be required (i)
to issue, register the transfer of or exchange any Security if such Security may
be among those selected for redemption during a period beginning at the opening
of business 15 days before


                                      35
<Page>


selection of the Securities to be redeemed under Section 1103 and ending at the
close of business on (A) if such Securities are issuable only as Registered
Securities, the day of the mailing of the relevant notice of redemption and (B)
if such Securities are issuable as Bearer Securities, the day of the first
publication of the relevant notice of redemption or, if such Securities are also
issuable as Registered Securities and there is no publication, the mailing of
the relevant notice of redemption, or (ii) to register the transfer of or
exchange any Registered Security so selected for redemption in whole or in part,
except, in the case of any Registered Security to be redeemed in part, the
portion thereof not to be redeemed, or (iii) to exchange any Bearer Security so
selected for redemption except that such a Bearer Security may be exchanged for
a Registered Security of that series and like tenor, provided that such
Registered Security shall be simultaneously surrendered for redemption, or (iv)
to issue, register the transfer of or exchange any Security which has been
surrendered for repayment at the option of the Holder, except the portion, if
any, of such Security not to be so repaid.

                  SECTION 306. Mutilated, Destroyed, Lost and Stolen Securities.
If any mutilated Security or a Security with a mutilated coupon appertaining to
it is surrendered to the Trustee or the Company, together with, in proper cases,
such security or indemnity as may be required by the Company or the Trustee to
save each of them or any agent of either of them harmless, the Company shall
execute and the Trustee shall authenticate and deliver in exchange therefor a
new Security of the same series and principal amount, containing identical terms
and provisions and bearing a number not contemporaneously outstanding, with
coupons corresponding to the coupons, if any, appertaining to the surrendered
Security. If there shall be delivered to the Company and to the Trustee (i)
evidence to their satisfaction of the destruction, loss or theft of any Security
or coupon, and (ii) such security or indemnity as may be required by them to
save each of them and any agent of either of them harmless, then, in the absence
of notice to the Company or the Trustee that such Security or coupon has been
acquired by a bona fide purchaser, the Company shall execute and upon its
request the Trustee shall authenticate and deliver, in lieu of any such
destroyed, lost or stolen Security or in exchange for the Security to which a
destroyed, lost or stolen coupon appertains (with all appurtenant coupons not
destroyed, lost or stolen), a new Security of the same series and principal
amount, containing identical terms and provisions and bearing a number not
contemporaneously outstanding, with coupons corresponding to the coupons, if
any, appertaining to such destroyed, lost or stolen Security or to the Security
to which such destroyed, lost or stolen coupon appertains.

                  Notwithstanding the provisions of the previous two paragraphs,
in case any such mutilated, destroyed, lost or stolen Security or coupon has
become or is about to become due and payable, the Company in its discretion may,
instead of issuing a new Security, with coupons corresponding to the coupons, if
any, appertaining to such destroyed, lost or stolen Security or to the Security
to which such destroyed, lost or stolen coupon appertains, pay such Security or
coupon; provided, however, that payment of principal of (and premium or
Make-Whole Amount, if any), and any interest on, Bearer Securities shall, except
as otherwise provided in Section 1002, be payable only at an office or agency
located outside the United States and, unless otherwise specified as
contemplated by Section 301, any interest on Bearer Securities shall be payable
only upon presentation and surrender of the coupons appertaining thereto. Upon
the issuance of any new Security under this Section, 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.


                                      36
<Page>


                  Every new Security of any series with its coupons, if any,
issued pursuant to this Section in lieu of any destroyed, lost or stolen
Security, or in exchange for a Security to which a destroyed, lost or stolen
coupon appertains, shall constitute an original additional contractual
obligation of the Company, whether or not the destroyed, lost or stolen Security
and its coupons, if any, or the destroyed, lost or stolen coupon shall be at any
time enforceable by anyone, and shall be entitled to all the benefits of this
Indenture equally and proportionately with any and all other Securities of that
series and their coupons, if any, duly issued hereunder.

                  The provisions of this Section are exclusive and shall
preclude (to the extent lawful) all other rights and remedies with respect to
the replacement or payment of mutilated, destroyed, lost or stolen Securities or
coupons.

                  SECTION 307. Payment of Interest; Interest Rights Preserved.
Except as otherwise specified with respect to a series of Securities in
accordance with the provisions of Section 301, interest on any Registered
Security that is payable, and is punctually paid or duly provided for, on any
Interest Payment Date shall be paid to the Person in whose name that Security
(or one or more Predecessor Securities) is registered at the close of business
on the Regular Record Date for such interest at the office or agency of the
Company maintained for such purpose pursuant to Section 1002; provided, however,
that each installment of interest on any Registered Security may at the
Company's option be paid by (i) mailing a check for such interest, payable to or
upon the written order of the Person entitled thereto pursuant to Section 308,
to the address of such Person as it appears on the Security Register or (ii)
transfer to an account maintained by the payee located inside the United States.

                  Unless otherwise provided as contemplated by Section 301 with
respect to the Securities of any series, payment of interest may be made, in the
case of a Bearer Security, by transfer to an account maintained by the payee
with a bank located outside the United States.

                  Unless otherwise provided as contemplated by Section 301,
every permanent global Security will provide that interest, if any, payable on
any Interest Payment Date will be paid to DTC, Euroclear and/or Clearstream, as
the case may be, with respect to that portion of such permanent global Security
held for its account by Cede & Co. or the Common Depository, as the case may be,
for the purpose of permitting such party to credit the interest received by it
in respect of such permanent global Security to the accounts of the beneficial
owners thereof.

                  In case a Bearer Security of any series is surrendered in
exchange for a Registered Security of such series after the close of business
(at an office or agency in a Place of Payment for such series) on any Regular
Record Date and before the opening of business (at such office or agency) on the
next succeeding Interest Payment Date, such Bearer Security shall be surrendered
without the coupon relating to such Interest Payment Date and interest will not
be payable on such Interest Payment Date in respect of the Registered Security
issued in exchange for such Bearer Security, but will be payable only to the
Holder of such coupon when due in accordance with the provisions of this
Indenture. Except as otherwise specified with respect to a series of Securities
in accordance with the provisions of Section 301, any interest on any Registered
Security of any series that is payable, but is not punctually paid or duly
provided for, on any Interest Payment Date (herein called "Defaulted Interest")
shall forthwith cease to be payable to the registered Holder thereof on the
relevant Regular Record Date by virtue of having been such


                                      37
<Page>


Holder, and such Defaulted Interest may be paid by the Company, at its election
in each case, as provided in clause (1) or (2) below:

                  (1) The Company may elect to make payment of any Defaulted
                  Interest to the Persons in whose names the Registered
                  Securities of such series (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 Registered
                  Security of such series and the date of the proposed payment
                  (which shall not be less than 20 days after such notice is
                  received by the Trustee), and at the same time the Company
                  shall deposit with the Trustee an amount of money in the
                  currency or currencies, currency unit or units or composite
                  currency or currencies in which the Securities of such series
                  are payable (except as otherwise specified pursuant to Section
                  301 for the Securities of such series) 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 on or 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 be not more than 15 days
                  and not 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 Holder of Registered
                  Securities of such series at his address as it appears in the
                  Security Register not less than 10 days prior to such Special
                  Record Date. The Trustee may, in its discretion, in the name
                  and at the expense of the Company, cause a similar notice to
                  be published at least once in an Authorized Newspaper in each
                  Place of Payment, but such publications shall not be a
                  condition precedent to the establishment of 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 the Registered Securities of such
                  series (or their respective Predecessor Securities) are
                  registered at the close of business on such Special Record
                  Date and shall no longer be payable pursuant to the following
                  clause (2). In case a Bearer Security of any series is
                  surrendered at the office or agency in a Place of Payment for
                  such series in exchange for a Registered Security of such
                  series after the close of business at such office or agency on
                  any Special Record Date and before the opening of business at
                  such office or agency on the related proposed date for payment
                  of Defaulted Interest, such Bearer Security shall be
                  surrendered without the coupon relating to such proposed date
                  of payment and Defaulted Interest will not be payable on such
                  proposed date of payment in respect of the Registered Security
                  issued in exchange for such Bearer Security, but will be
                  payable only to the Holder of such coupon when due in
                  accordance with the provisions of this Indenture.


                                      38
<Page>


                  (2) The Company may make payment of any Defaulted Interest on
                  the Registered Securities of any series 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.

                  Subject to the foregoing provisions of this Section and
Section 305, each Security delivered under this Indenture upon registration of
transfer of or in exchange for or in lieu of any other Security shall carry the
rights to interest accrued and unpaid, and to accrue, which were carried by such
other Security.

                  SECTION 308. Persons Deemed Owners. Prior to due presentment
of a Registered Security for registration of transfer, the Company, the Trustee
and any agent of the Company or the Trustee may treat the Person in whose name
such Registered Security is registered as the owner of such Security for the
purpose of receiving payment of principal of (and premium or Make-Whole Amount,
if any), and (subject to Sections 305 and 307) interest on, such Registered
Security and for all other purposes whatsoever, whether or not such Registered
Security be overdue, and neither the Company, the Trustee nor any agent of the
Company or the Trustee shall be affected by notice to the contrary. All such
payments so made to any such Person, or upon such Person's order, shall be
valid, and, to the extent of the sum or sums so paid, effectual to satisfy and
discharge the liability for money payable upon any such Security.

                  Title to any Bearer Security and any coupons appertaining
thereto shall pass by delivery. The Company, the Trustee and any agent of the
Company or the Trustee may treat the Holder of any Bearer Security and the
Holder of any coupon as the absolute owner of such Security or coupon for the
purpose of receiving payment thereof or on account thereof and for all other
purposes whatsoever, whether or not such Security or coupon be overdue, and
neither the Company, the Trustee nor any agent of the Company or the Trustee
shall be affected by notice to the contrary.

                  No Holder of any beneficial interest in any Global Security
held on its behalf by a depository shall have any rights under this Indenture
with respect to such Global Security and such depository shall be treated by the
Company, the Trustee, and any agent of the Company or the Trustee as the owner
of such Global Security for all purposes whatsoever. None of the Company, the
Trustee, any Paying Agent or the Security Registrar will have any responsibility
or liability for any aspect of the records relating to or payments made on
account of beneficial ownership interests of a Global Security or for
maintaining, supervising or reviewing any records relating to such beneficial
ownership interests.

                  Notwithstanding the foregoing, with respect to any Global
Security, nothing herein shall prevent the Company, the Trustee, or any agent of
the Company or the Trustee, from giving effect to any written certification,
proxy or other authorization furnished by any depository, as a Holder, with
respect to such Global Security or impair, as between such depository and owners
of beneficial interests in such Global Security, the operation of customary
practices governing the exercise of the rights of such depository (or its
nominee) as Holder of such Global Security.

                  SECTION 309. Cancellation. All Securities and coupons
surrendered for payment, redemption, repayment at the option of the Holder,
conversion or registration of transfer or exchange or for credit against any
sinking fund payment shall, if surrendered to any Person other than the Trustee,
be delivered to the Trustee, and any such Securities and coupons and Securities
and coupons surrendered directly to the Trustee for any such purpose shall be
promptly cancelled by it. The Company may at any time deliver to the Trustee for
cancellation any Securities previously authenticated and delivered hereunder
which the Company may have acquired in any manner whatsoever, and may deliver to
the Trustee (or to any other Person for delivery to the Trustee) for
cancellation any Securities previously authenticated hereunder which the Company
has not issued and sold, and all Securities so delivered shall be promptly
cancelled by the Trustee. If the Company shall so 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
surrendered to the Trustee for cancellation. No Securities shall be
authenticated in lieu of or in exchange for any Securities cancelled as provided
in this Section, except as expressly permitted by this Indenture. Cancelled
Securities and coupons held by the Trustee shall be destroyed by the Trustee and
the Trustee shall deliver a certificate of such destruction to the Company,
unless the Trustee is otherwise directed by a Company Order.

                  SECTION 310. Computation of Interest. Except as otherwise
specified as contemplated by Section 301 with respect to Securities of any
series, interest on the Securities of each series shall be computed on the basis
of a 360-day year consisting of twelve 30-day months.

                    ARTICLE FOUR - SATISFACTION AND DISCHARGE

                  SECTION 401. Satisfaction and Discharge of Indenture. This
Indenture shall upon Company Request cease to be of further effect with respect

surviving rights of registration of transfer or exchange of Securities of such
series herein expressly provided for), and the Trustee, upon receipt of a
Company Order, and at the expense of the Company, shall execute instruments in
form and substance satisfactory to the Trustee and the Company acknowledging

                  Bearer Securities surrendered for exchange for Registered
                  Securities and maturing after such exchange, whose surrender
                  is not required or has been waived as provided in Section 305,
                  (ii) Securities and coupons of such series which have been
                  destroyed, lost or stolen and which have been replaced or paid

                  Securities called for redemption and maturing after the
                  relevant Redemption Date, whose surrender has been waived as
                  provided in Section 1106, and (iv) Securities and coupons of
                  such series for whose payment money has theretofore been
                  deposited in trust or segregated and held in trust by the
                  Company and thereafter repaid to the Company or discharged
                  from such trust, as provided in Section 1003) have been
                  delivered to the Trustee for cancellation; or

                           in the name, and at the expense, of the Company,

                  and the Company, in the case of (i), (ii) or (iii) above, has
                  irrevocably deposited or caused to be deposited with the
                  Trustee as trust funds in trust for the purpose an amount in
                  the currency or currencies, currency unit or units or
                  composite currency or currencies in which the Securities of
                  such series are payable, sufficient to pay and discharge the
                  entire indebtedness on such Securities and such coupons not
                  theretofore delivered to the Trustee for cancellation, for
                  principal (and premium or Make-Whole Amount, if any) and
                  interest to the date of such deposit (in the case of
                  Securities which have become due and payable) or to the Stated
                  Maturity or Redemption Date, as the case may be;

                  (2) the Company has paid or caused to be paid all other sums
                  payable hereunder by the Company; and

                  (3) the Company has delivered to the Trustee an Officers'
                  Certificate and an Opinion of Counsel, each stating that all
                  conditions precedent herein provided for relating to the
                  satisfaction and discharge of this Indenture as to such series
                  have been complied with.


Notwithstanding the satisfaction and discharge of this Indenture, the
obligations of the Company to the Trustee and any predecessor Trustee under
Section 606, the obligations of the Company to any Authenticating Agent under
Section 611 and, if money shall have been deposited with and held by the Trustee
pursuant to subclause (B) of clause (1) of this Section, the obligations of the
Trustee under Section 402 and the last paragraph of Section 1003 shall survive.

                  SECTION 402. Application of Trust Funds. Subject to the
provisions of the last paragraph of Section 1003, all money deposited with the
Trustee pursuant to Section 401 shall be held in trust and applied by it, in
accordance with the provisions of the Securities, the coupons and this
Indenture, to the payment, either directly or through any Paying Agent
(including the Company acting as its own Paying Agent) as the Trustee may
determine, to the Persons entitled thereto, of the principal (and premium or
Make-Whole Amount, if any), and any interest for whose payment such money has
been deposited with or received by the Trustee, but such money need not be
segregated from other funds except to the extent required by law.

                             ARTICLE FIVE - REMEDIES

                  SECTION 501. Events of Default. "Event of Default," wherever
used herein with respect to any particular series of Securities, means any one
of the following events (whatever the reason for such Event of Default and
whether or not it shall be voluntary or involuntary or be effected by operation
of law or pursuant to any judgment, decree or order of any court or any order,
rule or regulation of any administrative or governmental body):

                  (1) default in the payment of any interest on any Security of
                  that series or of any coupon appertaining thereto, when such
                  interest or coupon becomes due and payable, and continuance of
                  such default for a period of 30 days; or

                  (2) default in the payment of the principal of (or premium or
                  Make-Whole Amount, if any, on) any Security of that series
                  when it becomes due and payable at its Maturity; or

                  (3) default in the deposit of any sinking fund payment, when
                  and as due by the terms of any Security of that series; or

                  (4) default in the performance, or breach, of any covenant or
                  warranty of the Company in this Indenture with respect to any
                  Security of that series (other than a covenant or warranty a
                  default in whose performance or whose breach is elsewhere in
                  this Section specifically dealt with), and continuance of such
                  default or breach for a period of 60 days after there has been
                  given, by registered or certified mail, to the Company by the
                  Trustee or to the Company and the Trustee by the Holders of at
                  least 25% in principal amount of the Outstanding Securities of
                  that series a written notice specifying such default or breach
                  and requiring it to be remedied and stating that such notice
                  is a "Notice of Default" hereunder; or

                  (5) default under any bond, debenture, note, mortgage,
                  indenture or instrument under which there may be issued or by
                  which there may be secured or evidenced any indebtedness for
                  money borrowed by the Company (or by any Subsidiary, the
                  repayment of which the Company has guaranteed or for which the
                  Company is directly responsible or liable as obligor or
                  guarantor), having an aggregate principal amount outstanding
                  of at least $100,000,000, whether such indebtedness now exists
                  or shall hereafter be created, which default shall have
                  resulted in such indebtedness becoming or being declared due
                  and payable prior to the date on which it would otherwise have
                  become due and payable, without such indebtedness having been
                  discharged, or such acceleration having been rescinded or
                  annulled, within a period of 10 days after there shall have
                  been given, by registered or certified mail, to the Company by
                  the Trustee or to the Company and the Trustee by the Holders
                  of at least 10% in principal amount of the Outstanding
                  Securities of that series a written notice specifying such
                  default and requiring the Company to cause such indebtedness
                  to be discharged or cause such acceleration to be rescinded or
                  annulled and stating that such notice is a "Notice of Default"
                  hereunder; or

                  (6) a court of competent jurisdiction enters one or more
                  judgments, orders or decrees in an aggregate amount (excluding
                  amounts covered by insurance) in excess of $100,000,000 and
                  such judgments, orders or decrees remain undischarged,
                  unstayed and unsatisfied in an aggregate amount (excluding
                  amounts covered by insurance) in excess of $100,000,000 for a
                  period of 30 consecutive days; or

                  (7) the Company or any Significant Subsidiary pursuant to or
                  within the meaning of any Bankruptcy Law:

                           (A) commences a voluntary case,

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

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

                           (D) makes a general assignment for the benefit of its

                  decree under any Bankruptcy Law that:

                           (A) is for relief against the Company or any
                  Significant Subsidiary in an involuntary case,

                           (B) appoints a Custodian of the Company or any
                  Significant Subsidiary or for all or substantially all of

                  unstayed and in effect for 90 days; or

                  (9) any other Event of Default provided with respect to
                  Securities of that series.


As used in this Section 501, the term "Bankruptcy Law" means title 11, U.S. Code
or any similar Federal or state law for the relief of debtors and the term
"Custodian" means any receiver, trustee, assignee, liquidator or other similar
official under any Bankruptcy Law.

                  SECTION 502. Acceleration of Maturity; Rescission and
Annulment. If an Event of Default with respect to Securities of any series at
the time Outstanding occurs and is continuing, then and in every such case the
Trustee or the Holders of not less than 25% in principal amount of the
Outstanding Securities of that series may declare the principal amount (or, if
Securities of that Series are Original Issue Discount Securities or Indexed
Securities, such portion of the principal as may be specified in the terms
thereof) of all the Securities of that series to be due and payable immediately,
by a notice in writing to the Company (and to the Trustee if given by the
Holders), and upon any such declaration such principal or specified portion
thereof shall become immediately due and payable. At any time after such a
declaration


                                       43
<Page>

of acceleration with respect to Securities of any series has been made and
before a judgment or decree for payment of the money due has been obtained by
the Trustee as hereinafter in this Article provided, the Holders of a
majority in principal amount of the Outstanding Securities of that series, by
written notice to the Company and the Trustee, may rescind and annul such
declaration of acceleration and its consequences if:

                  (1) the Company has paid or deposited with the Trustee a sum
                  sufficient to pay in the currency, currency unit or composite
                  currency in which the Securities of such series are payable
                  (except as otherwise specified pursuant to Section 301 for the
                  Securities of such series):

                           (A) all overdue installments of interest on all
                  Outstanding Securities of that series and any related coupons,

                           (B) the principal of (and premium or Make-Whole
                  Amount, if any, on) any Outstanding Securities of that series
                  which have become due otherwise than by such declaration of
                  acceleration and interest thereon at the rate or rates borne
                  by or provided for in such Securities,

                           (C) to the extent that payment of such interest is
                  lawful, interest upon overdue installments of interest at the
                  rate or rates borne by or provided for in such Securities, and

                           (D) all sums paid or advanced by the Trustee
                  hereunder and the reasonable compensation, expenses,
                  disbursements and advances of the Trustee, its agents and
                  counsel; and

                  (2) all Events of Default with respect to Securities of that
                  series, other than the nonpayment of the principal of (or
                  premium or Make-Whole Amount, if any) or interest on
                  Securities of that series which have become due solely by such
                  declaration of acceleration, have been cured or waived as
                  provided in Section 513.

No such rescission shall affect any subsequent default or impair any right
consequent thereon.

                  SECTION 503. Collection of Indebtedness and Suits for
Enforcement by Trustee. The Company covenants that if:

                  (1) default is made in the payment of any installment of
                  interest on any Security of any series and any related coupon
                  when such interest becomes due and payable and such default
                  continues for a period of 30 days, or

                  (2) default is made in the payment of the principal of (or
                  premium or Make-Whole Amount, if any, on) any Security of any
                  series at its Maturity,


then the Company will, upon demand of the Trustee, pay to the Trustee, for the
benefit of the Holders of such Securities of such series and coupons, the whole
amount then due and payable on such Securities and coupons for principal (and
premium or Make-Whole Amount, if any) and interest, with interest upon any
overdue principal (and premium or Make-Whole Amount, if any)


                                       44
<Page>

and, to the extent that payment of such interest shall be legally
enforceable, upon any overdue installments of interest at the rate or rates
borne by or provided for in such Securities, and, in addition thereto, such
further amount as shall be sufficient to cover the costs and expenses of
collection, including the reasonable compensation, expenses, disbursements
and advances of the Trustee, its agents and counsel.

                  If the Company fails to pay such amounts forthwith upon such
demand, the Trustee, in its own name and as trustee of an express trust, may
institute a judicial proceeding for the collection of the sums so due and
unpaid, and may prosecute such proceeding to judgment or final decree, and may
enforce the same against the Company or any other obligor upon such Securities
of such series and collect the moneys adjudged or decreed to be payable in the
manner provided by law out of the property of the Company or any other obligor
upon such Securities of such series, wherever situated.

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

                  SECTION 504. Trustee May File Proofs of Claim. In case of the
pendency of any receivership, insolvency, liquidation, bankruptcy,
reorganization, arrangement, adjustment, composition or other judicial
proceeding relative to the Company or any other obligor upon the Securities or
the property of the Company or of such other obligor or their creditors, the
Trustee (irrespective of whether the principal of the Securities of any series
shall then be due and payable as therein expressed or by declaration or
otherwise and irrespective of whether the Trustee shall have made any demand on
the Company for the payment of overdue principal, premium or Make-Whole Amount,
if any, or interest) shall be entitled and empowered, by intervention in such
proceeding or otherwise:

                  (i) to file and prove a claim for the whole amount, or such
                  lesser amount as may be provided for in the Securities of such
                  series, of principal (and premium or Make-Whole Amount, if
                  any) and interest owing and unpaid in respect of the
                  Securities and to file such other papers or documents as may
                  be necessary or advisable in order to have the claims of the
                  Trustee (including any claim for the reasonable compensation,
                  expenses, disbursements and advances of the Trustee, its
                  agents and counsel) and of the Holders allowed in such
                  judicial proceeding, and

                  (ii) to collect and receive any moneys or other property
                  payable or deliverable on any such claims and to distribute
                  the same; and any custodian, receiver, assignee, trustee,
                  liquidator, sequestrator (or other similar official) in any
                  such judicial proceeding is hereby authorized by each Holder
                  of Securities of such series and coupons to make such payments
                  to the Trustee, and in the event that the Trustee shall
                  consent to the making of such payments directly to the
                  Holders, to pay to the Trustee any amount due to it for the
                  reasonable compensation, expenses, disbursements and advances
                  of the Trustee and any predecessor

                  Trustee, their agents and counsel, and any other amounts due
                  the Trustee or any predecessor Trustee under Section 606.
                  Nothing herein contained shall be deemed to authorize the
                  Trustee to authorize or consent to or accept or adopt on
                  behalf of any Holder of a Security or coupon any plan of
                  reorganization, arrangement, adjustment or composition
                  affecting the Securities or coupons or the rights of any
                  Holder thereof, or to authorize the Trustee to vote in
                  respect of the claim of any Holder of a Security or coupon in
                  any such proceeding.

                  In any proceedings brought by the Trustee (and also any
proceedings involving the interpretation of any provision of this Indenture to
which the Trustee shall be a party) the Trustee shall be held to represent all
the Holders of the Securities, and it shall not be necessary to make any Holders
of the Securities parties to any such proceedings.

                  SECTION 505. Trustee May Enforce Claims Without Possession of
Securities or Coupons. All rights of action and claims under this Indenture or
any of the Securities or coupons may be prosecuted and enforced by the Trustee
without the possession of any of the Securities or coupons or the production
thereof in any proceeding relating thereto, and any such 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 the payment of the
reasonable compensation, expenses, disbursements and advances of the Trustee,
its agents and counsel, be for the ratable benefit of the Holders of the
Securities and coupons in respect of which such judgment has been recovered.

                  SECTION 506. Application of Money Collected. Any money
collected by the Trustee pursuant to this Article shall be applied in the
following order, at the date or dates fixed by the Trustee and, in case of the
distribution of such money on account of principal (or premium or Make-Whole
Amount, if any) or interest, upon presentation of the Securities or coupons, or
both, as the case may be, and the notation thereon of the payment if only
partially paid and upon surrender thereof if fully paid:

                  FIRST: To the payment of all amounts due the Trustee and any
predecessor Trustee under Section 606;

                  SECOND: To the payment of the amounts then due and unpaid upon
the Securities and coupons for principal (and premium or Make-Whole Amount, 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 aggregate amounts due and payable on such Securities and
coupons for principal (and premium or Make-Whole Amount, if any) and interest,
respectively; and

         THIRD:  To the payment of the remainder, if any, to the Company.

                  SECTION 507. Limitation on Suits. No Holder of any Security of
any series or any related coupon shall have any right to institute any
proceeding, judicial or otherwise, with respect to this Indenture, or for the
appointment of a receiver or trustee, or for any other remedy hereunder, unless:


                                       46
<Page>

                  (1) such Holder has previously given written notice to the
                  Trustee of a continuing Event of Default with respect to the
                  Securities of that series;

                  (2) the Holders of not less than 25% in principal amount of
                  the Outstanding Securities of that series shall have made
                  written request to the Trustee to institute proceedings in
                  respect of such Event of Default in its own name as Trustee
                  hereunder;

                  (3) such Holder or Holders have offered to the Trustee
                  indemnity reasonably satisfactory to the Trustee against the
                  costs, expenses and liabilities to be incurred in compliance
                  with such request;

                  (4) the Trustee for 60 days after its receipt of such notice,
                  request and offer of indemnity has failed to institute any
                  such proceeding; and

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


it being understood and intended that no one or more of such Holders shall have
any right in any manner whatever by virtue of, or by availing of, any provision
of this Indenture to affect, disturb or prejudice the rights of any other of
such Holders, or to obtain or to seek to obtain priority or preference over any
other of such Holders or to enforce any right under this Indenture, except in
the manner herein provided and for the equal and ratable benefit of all such
Holders.

                  SECTION 508. Unconditional Right of Holders to Receive
Principal, Premium or Make-Whole Amount, if any, and Interest. Notwithstanding
any other provision in this Indenture, the Holder of any Security or coupon
shall have the right which is absolute and unconditional to receive payment of
the principal of (and premium or Make-Whole Amount, if any) and (subject to
Sections 305 and 307) interest on such Security or payment of such coupon on the
respective due dates expressed in such Security or coupon (or, in the case of
redemption, on the Redemption Date) and to institute suit for the enforcement of
any such payment, and such rights shall not be impaired without the consent of
such Holder.

                  SECTION 509. Restoration of Rights and Remedies. If the
Trustee or any Holder of a Security or coupon has instituted any proceeding to
enforce any right or remedy under this Indenture and such proceeding has been
discontinued or abandoned for any reason, or has been determined adversely to
the Trustee or to such Holder, then and in every such case, the Company, the
Trustee and the Holders of Securities and coupons shall, subject to any
determination in such proceeding, be restored severally and respectively to
their former positions hereunder and thereafter all rights and remedies of the
Trustee and the Holders shall continue as though no such proceeding had been
instituted.

                  SECTION 510. Rights and Remedies Cumulative. Except as
otherwise provided with respect to the replacement or payment of mutilated,
destroyed, lost or stolen Securities or coupons in the last paragraph of Section
306, no right or remedy herein conferred upon or reserved to the Trustee or to
the Holders of Securities or coupons is intended to be exclusive of any other
right or remedy, and every right and remedy shall, to the extent permitted by
law, be


                                       47
<Page>

cumulative and in addition to every other right and remedy given hereunder or
now or hereafter existing at law or in equity or otherwise. The assertion or
employment of any right or remedy hereunder, or otherwise, shall not prevent
the concurrent assertion or employment of any other appropriate right or
remedy.

                  SECTION 511. Delay or Omission Not Waiver. No delay or
omission of the Trustee or of any Holder of any Security or coupon to exercise
any right or remedy accruing upon any Event of Default shall impair any such
right or remedy or constitute a waiver of any such Event of Default or an
acquiescence therein. Every right and remedy given by this Article or by law to
the Trustee or to the Holders may be exercised from time to time, and as often
as may be deemed expedient, by the Trustee or by the Holders of Securities or
coupons, as the case may be.

                  SECTION 512. Control by Holders of Securities. The Holders of
not less than a majority in principal amount of the Outstanding Securities of
any series 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 the Securities of
such series, provided that

                  (1) such direction shall not be in conflict with any rule of
                  law or with this Indenture,

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

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

                  Nothing in this Indenture shall impair the right of the
Trustee in its discretion to take any action deemed proper by the Trustee and
which is not inconsistent with such direction by Holders.

                  SECTION 513. Waiver of Past Defaults. The Holders of not less
than a majority in principal amount of the Outstanding Securities of any series
may on behalf of the Holders of all the Securities of such series and any
related coupons waive any past default hereunder with respect to such series and
its consequences, except a default

                  (1) in the payment of the principal of (or premium or
                  Make-Whole Amount, if any) or interest on any Security of such
                  series or any related coupons, or

                  (2) in respect of a covenant or provision hereof which under
                  Article Nine cannot be modified or amended without the consent
                  of the Holder of each Outstanding Security of such series
                  affected. Upon any such waiver, such default shall cease to
                  exist, and any Event of Default arising therefrom shall be
                  deemed to have been cured, for every purpose of this
                  Indenture; but no such waiver shall extend to any subsequent
                  or other default or Event of Default or impair any right
                  consequent thereon.


                                       48

                  SECTION 514. Waiver of Usury, Stay or Extension Laws. The
Company covenants (to the extent that it may lawfully do so) that it will not at
any time insist upon, or plead, or in any manner whatsoever claim or take the
benefit or advantage of, any usury, stay or extension law wherever enacted, now
or at any time hereafter in force, which may affect the covenants or the
performance of this Indenture; and the Company (to the extent that it may
lawfully do so) hereby expressly waives all benefit or advantage of any such
law, and covenants that it will not hinder, delay or impede the execution of any
power herein granted to the Trustee, but will suffer and permit the execution of
every such power as though no such law had been enacted.

                  SECTION 515. Undertaking for Costs. All parties to this
Indenture agree, and each Holder of any Security by his acceptance thereof shall
be deemed to have agreed, that any court may in its discretion require, in any
suit for the enforcement of any right or remedy under this Indenture, or in any
suit against the Trustee for any action taken or omitted by it as Trustee, the
filing by any party litigant in such suit of an undertaking to pay the costs of
such suit, and that such court may in its discretion assess reasonable costs,
including reasonable attorneys' fees, 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 Holder, or group
of Holders, holding in the aggregate more than 10% in principal amount of the
Outstanding Securities of any series, or to any suit instituted by any Holder
for the enforcement of the payment of the principal of (or premium or Make-Whole
Amount, if any) or interest on any Security on or after the respective Stated
Maturities expressed in such Security (or, in the case of redemption, on or
after the Redemption Date).

                            ARTICLE SIX - THE TRUSTEE

                  SECTION 601. Notice of Defaults. Within 90 days after the
occurrence of any default hereunder with respect to the Securities of any
series, the Trustee shall transmit in the manner and to the extent provided in
TIA Section 313(c), notice of such default hereunder known to the Trustee,
unless such default shall have been cured or waived; provided, however, that,
except in the case of a default in the payment of the principal of (or premium
or Make-Whole Amount, if any) or interest on any Security of such series, or in
the payment of any sinking or purchase fund installment with respect to the
Securities of such 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 the Securities and coupons of such series; and provided further that
in the case of any default or breach of the character specified in Section
501(4) with respect to the Securities and coupons of such series, no such notice
to Holders shall be given until at least 60 days after the occurrence thereof.
For the purpose of this Section, the term "default" means any event which is, or
after notice or lapse of time or both would become, an Event of Default with
respect to the Securities of such series.

                  SECTION 602. Certain Rights of Trustee. Subject to the
provisions of TIA Section 315(a) through 315(d):


                                       49
<Page>

                  (1) the Trustee may rely and shall be protected in acting or
                  refraining from acting upon any resolution, certificate,
                  statement, instrument, opinion, report, notice, request,
                  direction, consent, order, bond, debenture, note, coupon or
                  other paper or document believed by it to be genuine and to
                  have been signed or presented by the proper party or parties;

                  (2) any request or direction of the Company mentioned herein
                  shall be sufficiently evidenced by a Company Request or
                  Company Order (other than delivery of any Security, together
                  with any coupons appertaining thereto, to the Trustee for
                  authentication and delivery pursuant to Section 303 which
                  shall be sufficiently evidenced as provided therein) and any
                  resolution of the Board of Directors may be sufficiently
                  evidenced by a Board Resolution;

                  (3) whenever in the administration of this Indenture the
                  Trustee shall deem it desirable that a matter be proved or
                  established prior to taking, suffering or omitting any action
                  hereunder, the Trustee (unless other evidence be herein
                  specifically prescribed) may, in the absence of bad faith on
                  its part, rely upon an Officers' Certificate;

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

                  (5) the Trustee shall be under no obligation to exercise any
                  of the rights or powers vested in it by this Indenture at the
                  request or direction of any of the Holders of Securities of
                  any series or any related coupons pursuant to this Indenture,
                  unless such Holders shall have offered to the Trustee security
                  or indemnity reasonably satisfactory to the Trustee against
                  the costs, expenses and liabilities which might be incurred by
                  it in compliance with such request or direction;

                  (6) 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, direction, consent, order, bond, debenture, note,
                  coupon or other paper or document, unless requested in writing
                  so to do by the Holders of not less than a majority in
                  aggregate principal amount of the Outstanding Securities of
                  any series; provided that, if the payment within a reasonable
                  time to the Trustee of the costs, expenses or liabilities
                  likely to be incurred by it in the making of such
                  investigation is, in the opinion of the Trustee, not
                  reasonably assured to the Trustee by the security afforded to
                  it by the terms of this Indenture, the Trustee may require
                  reasonable indemnity against such expenses or liabilities as a
                  condition to proceeding; the reasonable expenses of every such
                  examination shall be paid by the Holders or, if paid by the
                  Trustee, shall be repaid by the Holders upon demand. The
                  Trustee, in its discretion, may make such further inquiry or
                  investigation into such facts or matters as it may see fit,
                  and, if the Trustee shall determine to make such further
                  inquiry or investigation, it shall be entitled to


                                       50

<Page>

                  examine the books, records and premises of the Company,
                  relevant to the facts or matters that are the subject of its
                  inquiry, personally or by agent or attorney;

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

                  (8)  the Trustee shall not be liable for any action taken,
                  suffered or omitted by it in good faith and reasonably
                  believed by it to be authorized or within the discretion or
                  rights or powers conferred upon it by this Indenture.

                  The Trustee shall not be required to expend or risk its own
funds or otherwise incur any financial liability in the performance of any of
its duties hereunder, or in the exercise of any of its rights or powers, if it
shall have reasonable grounds for believing that repayment of such funds or
adequate indemnity against such risk or liability is not reasonably assured to
it.

                  Except during the continuance of an Event of Default, the
Trustee undertakes to perform 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.

                  SECTION 603. Not Responsible for Recitals or Issuance of
Securities. The recitals contained herein and in the Securities, except the
Trustee's certificate of authentication, and in any coupons shall be taken as
the statements of the Company, and neither the Trustee nor any Authenticating
Agent assumes any responsibility for their correctness. The Trustee makes no
representations as to the validity or sufficiency of this Indenture or of the
Securities or coupons, except that the Trustee represents that it is duly
authorized to execute and deliver this Indenture, authenticate the Securities
and perform its obligations hereunder. Neither the Trustee nor any
Authenticating Agent shall be accountable for the use or application by the
Company of Securities or the proceeds thereof.

                  SECTION 604. May Hold Securities. The Trustee, any Paying
Agent, Security Registrar, Authenticating Agent or any other agent of the
Company, in its individual or any other capacity, may become the owner or
pledgee of Securities and coupons and, subject to TIA Sections 310(b) and 311,
may otherwise deal with the Company with the same rights it would have if it
were not Trustee, Paying Agent, Security Registrar, Authenticating Agent or such
other agent.

                  SECTION 605. Money Held in Trust. Money held by the Trustee in
trust hereunder 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
money received by it hereunder except as otherwise agreed with the Company.

         SECTION 606.  Compensation and Reimbursement.  The Company agrees:

                  (1)  to pay to the Trustee from time to time reasonable
                  compensation for all services rendered by it hereunder (which
                  compensation shall not be limited by any provision of law in
                  regard to the compensation of a trustee of an express trust);


                                       51
<Page>

                  (2)  except as otherwise expressly provided herein, to
                  reimburse each of the Trustee and any predecessor Trustee upon
                  its request for all reasonable expenses, disbursements and
                  advances incurred or made by the Trustee in accordance with
                  any provision of this Indenture (including the reasonable
                  compensation and the reasonable expenses and disbursements of
                  its agents and counsel), except any such expense, disbursement
                  or advance as may be attributable to its negligence or bad
                  faith; and

                  (3)  to indemnify each of the Trustee and any predecessor
                  Trustee for, and to hold it harmless against, any loss,
                  liability or expense incurred without negligence or bad faith
                  on its part, arising out of or in connection with the
                  acceptance or administration of the trust or trusts hereunder,
                  including the costs and expenses of defending itself against
                  any claim or liability in connection with the exercise or
                  performance of any of its powers or duties hereunder.

                  When the Trustee incurs expenses or renders services in
connection with an Event of Default specified in Section 501(7) or Section
501(8), the expenses (including the reasonable charges and expenses of its
counsel) and the compensation for the services are intended to constitute
expenses of administration under any applicable Federal or state bankruptcy,
insolvency or other similar law.

                  As security for the performance of the obligations of the
Company under this Section, the Trustee shall have a lien prior to the
Securities upon all property and funds held or collected by the Trustee as
such, except funds held in trust for the payment of principal of (or premium or
Make-Whole Amount, if any) or interest on particular Securities or any coupons.

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

                  SECTION 607. Corporate Trustee Required; Eligibility;
Conflicting Interests. There shall at all times be a Trustee hereunder which
shall be eligible to act as Trustee under TIA Section 310(a)(1) and shall have
at all times a combined capital and surplus of at least $50,000,000. If the
Trustee publishes reports of condition at least annually, pursuant to law or
the requirements of Federal, state, territorial or District of Columbia
supervising or examining authority, then for the purposes of this Section, the
combined capital and surplus of the Trustee shall be deemed to be its combined
capital and surplus as set forth in its most recent report of condition so
published. If at any time the Trustee shall cease to be eligible in accordance
with the provisions of this Section, it shall resign immediately in the manner
and with the effect hereinafter specified in this Article. Neither the Company
nor any Person directly or indirectly controlling, controlled by, or under

                  (b)  The Trustee may resign at any time with respect to the
                  Securities of one or more series by giving written notice
                  thereof to the Company. If an instrument of acceptance by a
                  successor Trustee shall not have been delivered to the Trustee
                  within 30 days after the giving of such notice of resignation,
                  the resigning Trustee may petition any court of competent
                  jurisdiction for the appointment of a successor Trustee.

                  (c)  The Trustee may be removed at any time with respect to
                  the Securities of any series by Act of the Holders of a
                  majority in principal amount of the Outstanding Securities of
                  such series delivered to the Trustee and to the Company.

                  (d)  If at any time:

                       (1)  the Trustee shall fail to comply with the provisions
                  of TIA Section 310(b) after written request therefor by the
                  Company or by any Holder of a Security who has been a bona
                  fide Holder of a Security for at least six months, or

                       (2)  the Trustee shall cease to be eligible under
                  Section 607 and shall fail to resign after written request
                  therefor by the Company or by any Holder of a Security who has
                  been a bona fide Holder of a Security for at least six months,
                  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, (i) the Company by or pursuant to a Board Resolution may
remove the Trustee and appoint a successor Trustee with respect to all
Securities, or (ii) subject to TIA Section 315(e), any Holder of a Security who
has been a bona fide Holder of a Security for at least six months may, on behalf
of himself and all others similarly situated, petition any court of competent
jurisdiction for the removal of the Trustee with respect to all Securities and
the appointment of a successor Trustee or Trustees.

                  (e)  If the Trustee shall resign, be removed or become
                  incapable of acting, or if a vacancy shall occur in the office
                  of Trustee for any cause with respect to the Securities of one
                  or more series, the Company, by or pursuant to a Board
                  Resolution, shall promptly appoint a successor Trustee or
                  Trustees with respect to the Securities of that or those
                  series (it being understood that any such successor Trustee
                  may be appointed with respect to the Securities of one or more
                  or all of such series and that at any time there shall be only
                  one Trustee with respect to the Securities of any particular
                  series). If, within one year after such resignation, removal
                  or incapability, or the occurrence of such vacancy, a
                  successor Trustee with respect to the Securities of any series
                  shall be appointed by Act of the Holders of a majority in
                  principal amount of the Outstanding Securities of such series
                  delivered to the Company and the retiring Trustee, the
                  successor Trustee so appointed shall, forthwith upon its
                  acceptance of such appointment, become the


                                       53
<Page>

                  successor Trustee with respect to the Securities of such
                  series and to that extent supersede the successor Trustee
                  appointed by the Company. If no successor Trustee with
                  respect to the Securities of any series shall have been so
                  appointed by the Company or the Holders of Securities and
                  accepted appointment in the manner hereinafter provided, any
                  Holder of a Security who has been a bona fide Holder of a
                  Security of such series for at least six months may, on
                  behalf of himself and all others similarly situated, petition
                  any court of competent jurisdiction for the appointment of a
                  successor Trustee with respect to Securities of such series.

                  (f)  The Company shall give notice of each resignation and
                  each removal of the Trustee with respect to the Securities of
                  any series and each appointment of a successor Trustee with
                  respect to the Securities of any series in the manner provided
                  for notices to the Holders of Securities in Section 106. Each
                  notice shall include the name of the successor Trustee with
                  respect to the Securities of such series and the address of
                  its Corporate Trust Office.

         SECTION 609.  Acceptance of Appointment by Successor.

                  (a)  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 request of
                  the Company or the successor Trustee, such retiring Trustee
                  shall, upon payment of its charges, execute and deliver an
                  instrument transferring to such successor Trustee all the
                  rights, powers and trusts of the retiring Trustee, and shall
                  duly assign, transfer and deliver to such successor Trustee
                  all property and money held by such retiring Trustee
                  hereunder, subject nevertheless to its claim, if any, provided
                  for in Section 6.6.

                  (b)  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, pursuant to Article Nine hereof, 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) if the retiring Trustee is not retiring
                  with respect to all Securities, 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


                                       54
<Page>

                  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 and that each
                  such Trustee shall be trustee of a trust or trusts hereunder
                  separate and apart from any trust or trusts hereunder
                  administered by any other such Trustee; 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 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
                  all 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)  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 6.9, as the case may be.

                  (d)  No successor Trustee shall accept its appointment unless
                  at the time of such acceptance such successor Trustee shall be
                  qualified and eligible under this Article.

                  SECTION 610. Merger, Conversion, Consolidation or Succession
to Business. Any corporation into which the Trustee may be merged or converted
or with which it may be consolidated, or any corporation resulting from any
merger, conversion or consolidation to which the Trustee shall be a party, or
any corporation succeeding to all or substantially all of the corporate trust
business of the Trustee, shall be the successor of the Trustee hereunder,
provided such corporation shall be otherwise qualified and eligible under this
Article, without the execution or filing of any paper or any further act on the
part of any of the parties hereto. In case any Securities or coupons 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 or coupons so
authenticated with the same effect as if such successor Trustee had itself
authenticated such Securities or coupons. In case any Securities or coupons
shall not have been authenticated by such predecessor Trustee, any such
successor Trustee may authenticate and deliver such Securities or coupons, in
either its own name or that of its predecessor Trustee, with the full force and
effect which this Indenture provides for the certificate of authentication of
the Trustee.

                  SECTION 611. Appointment of Authenticating Agent. At any time
when any of the Securities remain Outstanding, the Trustee may appoint an
Authenticating Agent or Agents with respect to one or more series of Securities
which shall be authorized to act on behalf of the Trustee to authenticate
Securities of such series issued upon exchange, registration of transfer or
partial redemption or repayment 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. Any such
appointment shall be evidenced by an instrument in writing


                                       55
<Page>

signed by a Responsible Officer of the Trustee, a copy of which instrument
shall be promptly furnished to the Company. Wherever reference is made in this
Indenture to the authentication and delivery of Securities by the Trustee or
the Trustee's certificate of authentication, such reference shall be deemed to
include authentication and delivery on behalf of the Trustee by an
Authenticating Agent and a certificate of authentication executed on behalf of
the Trustee by an Authenticating Agent. Each Authenticating Agent shall be
acceptable to the Company and shall at all times be a bank or trust company or
corporation organized and doing business and in good standing under the laws of
the United States of America or of any state or the District of Columbia,
authorized under such laws to act as Authenticating Agent, having a combined
capital and surplus of not less than $50,000,000 and subject to supervision or
examination by Federal or state authorities. If such Authenticating Agent
publishes reports of condition at least annually, pursuant to law or the
requirements of the aforesaid supervising or examining authority, then for the
purposes of this Section, the combined capital and surplus of such
Authenticating Agent shall be deemed to be its combined capital and surplus as
set forth in its most recent report of condition so published. In case at any
time an Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, such Authenticating Agent shall resign immediately
in the manner and with the effect specified in this Section.

                  Any corporation into which an Authenticating Agent may be
merged or converted or with which it may be consolidated, or any corporation
resulting from any merger, conversion or consolidation to which such
Authenticating Agent shall be a party, or any corporation succeeding to the
corporate agency or corporate trust business of an Authenticating Agent, shall
continue to be an Authenticating Agent, provided such corporation shall be
otherwise eligible under this Section, without the execution or filing of any
paper or further act on the part of the Trustee or the Authenticating Agent.

                  An Authenticating Agent for any series of Securities may at
any time resign by giving written notice of resignation to the Trustee for such
series and to the Company. The Trustee for any series of Securities may at any
time terminate the agency of an Authenticating Agent by giving written notice
of termination to such Authenticating Agent and to the Company. Upon receiving
such a notice of resignation or upon such a termination, or in case at any time
such Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, the Trustee for such series may appoint a successor
Authenticating Agent which shall be acceptable to the Company and shall give
notice of such appointment to all Holders of Securities of the series with
respect to which such Authenticating Agent will serve in the manner set forth
in Section 106. Any successor Authenticating Agent upon acceptance of its
appointment hereunder shall become vested with all the rights, powers and
duties of its predecessor hereunder, with like effect as if originally named as
an Authenticating Agent herein. No successor Authenticating Agent shall be
appointed unless eligible under the provisions of this Section.

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

                  If an appointment with respect to one or more series is made
pursuant to this Section, the Securities of such series may have endorsed
thereon, in addition to or in lieu of the


                                       56
<Page>

Trustee's certificate of authentication, an alternate certificate of
authentication substantially in the following form:

                  This is one of the Securities of the series designated
therein referred to in the within-mentioned Indenture.

                                                         [             ]
                                                         as Trustee


Dated: ____________                             By:_____________________________
                                                      as Authenticating Agent

         SECTION 612.  Certain Duties and Responsibilities of the Trustee.

                  (a)  With respect to the Securities of any series, except
                  during the continuance of an Event of Default with respect to
                  the Securities of such series:

                       (1)  the Trustee undertakes to perform 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; and

                       (2)  in the absence of bad faith on its part, the Trustee
                  may conclusively rely, as to the truth of the statements and
                  the correctness of the opinions expressed therein, upon
                  certificates or opinions furnished to the Trustee and
                  conforming to the requirements of this Indenture; 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 shall not be under any
                  duty to verify the contents or accuracy thereof.

                  (b)  In case an Event of Default with respect to the
                  Securities of any series has occurred and is continuing, the
                  Trustee shall, with respect to Securities of such series,
                  exercise such of the rights and powers vested in it by this
                  Indenture, and use the same degree of care and skill in their
                  exercise, as a prudent man would exercise or use under the
                  circumstances in the conduct of his own affairs.

                  (c)  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)  this Subsection shall not be construed to limit the
                  effect of Subsection (a) of this Section;


                                       57
<Page>

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

                       (3)  the Trustee shall not be liable with respect to any
                  action taken or omitted to be taken by it in good faith in
                  accordance with the direction of the Holders of a majority in
                  principal amount of the Outstanding Securities of any series
                  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 such
                  series; and

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

                  (d)  Whether or not therein expressly so provided, every
                  provision of this Indenture relating to the conduct or
                  affecting the liability of or affording protection to the
                  Trustee shall be subject to the provisions of this Section
                  612.

        ARTICLE SEVEN - HOLDERS' LISTS AND REPORTS BY TRUSTEE AND COMPANY

                  SECTION 701. Disclosure of Names and Addresses of Holders.
Every Holder of Securities or coupons, by receiving and holding the same, agrees
with the Company and the Trustee that neither the Company nor the Trustee nor
any Authenticating Agent nor any Paying Agent nor any Security Registrar shall
be held accountable by reason of the disclosure of any information as to the
names and addresses of the Holders of Securities in accordance with TIA Section
312, 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 TIA Section 312(b).

                  authorizing such series, 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

        ARTICLE EIGHT - CONSOLIDATION, MERGER, SALE, LEASE OR CONVEYANCE

                  SECTION 801. Consolidations and Mergers of Company and Sales,
Leases and Conveyances Permitted Subject to Certain Conditions. The Company may
consolidate with, or sell, lease or convey all or substantially all of its
assets to, or merge with or into any other corporation, provided that in any
such case, (1) either the Company shall be the continuing corporation, or the
successor corporation shall be a corporation organized and existing under the


                                       59
<Page>

laws of the United States or a State thereof and such successor corporation
shall expressly assume the due and punctual payment of the principal of (and
premium or Make-Whole Amount, if any) and any interest on all of the Securities,
according to their tenor, and the due and punctual performance and observance of
all of the covenants and conditions of this Indenture to be performed by the
Company by supplemental indenture, complying with Article Nine hereof,
satisfactory to the Trustee, executed and delivered to the Trustee by such
corporation and (2) immediately after giving effect to such transaction and
treating any indebtedness which becomes an obligation of the Company or any
Subsidiary as a result thereof as having been incurred by the Company or such
Subsidiary at the time of such transaction, no Event of Default, and no event
which, after notice or the lapse of time, or both, would become an Event of
Default, shall have occurred and be continuing.

                  SECTION 802. Rights and Duties of Successor Corporation. In
case of any such consolidation, merger, sale, lease or conveyance and upon any
such assumption by the successor corporation, 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 the predecessor
corporation, except in the event of a lease, shall be relieved of any further
obligation 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, 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 corporation, 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 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.

                  In case of any such consolidation, merger, sale, lease or
conveyance, such changes in phraseology and form (but not in substance) may be
made in the Securities thereafter to be issued as may be appropriate.

                  SECTION 803. Officers' Certificate and Opinion of Counsel. Any
consolidation, merger, sale, lease or conveyance permitted under Section 801 is
also subject to the condition that the Trustee receive an Officers' Certificate
and an Opinion of Counsel to the effect that any such consolidation, merger,
sale, lease or conveyance, and the assumption by any successor corporation,
complies with the provisions of this Article and that all conditions precedent
herein provided for relating to such transaction have been complied with.

at any time and from time to time, may enter into one or more indentures
supplemental hereto, in form satisfactory to the Trustee, for any of the

                  (1) to evidence the succession of another Person to the
                  Company and the assumption by any such successor of the
                  covenants of the Company contained herein and in the
                  Securities; or

                  (2) to add to the covenants of the Company for the benefit of
                  the Holders of all or any series of Securities (and if such
                  covenants are to be for the benefit of less than all series of
                  Securities, stating that such covenants are expressly being
                  included solely for the benefit of such series) or to
                  surrender any right or power herein conferred upon the
                  Company; or

                  (3) to add any additional Events of Default for the benefit of
                  the Holders of all or any series of Securities (and if such
                  Events of Default are to be for the benefit of less than all
                  series of Securities, stating that such Events of Default are
                  expressly being included solely for the benefit of such
                  series); provided, however, that in respect of any such
                  additional Events of Default 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 right of the
                  Holders of a majority in aggregate principal amount of that or
                  those series of Securities to which such additional Events of
                  Default apply to waive such default; or

                  (4) to add to or change any of the provisions of this
                  Indenture to provide that Bearer Securities may be registrable
                  as to principal, to change or eliminate any restrictions on
                  the payment of principal of or premium or Make-Whole Amount,
                  if any, or interest on Bearer Securities, to permit Bearer
                  Securities to be issued in exchange for Registered Securities,
                  to permit Bearer Securities to be issued in exchange for
                  Bearer Securities of other authorized denominations or to
                  permit or facilitate the issuance of Securities in
                  uncertificated form, provided that any such action shall not
                  adversely affect the interests of the Holders of Securities of
                  any series or any related coupons in any material respect; or

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

                  (6) to secure the Securities; or

                  (7) to establish the form or terms of Securities of any series
                  and any related coupons as permitted by Sections 201 and 301;
                  or

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


                                       61

                  (9) to cure any ambiguity, to correct or supplement any
                  provision herein which may be defective or inconsistent with
                  any other provision herein, or to make any other provisions
                  with respect to matters or questions arising under this
                  Indenture which shall not be inconsistent with the provisions
                  of this Indenture, provided such provisions shall not
                  adversely affect the interests of the Holders of Securities of
                  any series or any related coupons in any material respect; or

                  (10) to supplement any of the provisions of this Indenture to
                  such extent as shall be necessary to permit or facilitate the
                  defeasance and discharge of any series of Securities pursuant
                  to Sections 401, 1402 and 1403; provided that any such action
                  shall not adversely affect the interests of the Holders of
                  Securities of such series and any related coupons or any other
                  series of Securities in any material respect; or

                  (11) to make provisions with respect to Holders' rights of
                  conversion with respect to any series of Securities pursuant
                  to Articles Seventeen.

                  SECTION 902. Supplemental Indentures with Consent of Holders.
With the consent of the Holders of not less than a majority in principal amount
of all Outstanding Securities affected by such supplemental indenture, by Act of
said Holders delivered to the Company and the Trustee, the Company, when
authorized by or pursuant to a Board Resolution, and the Trustee may enter into
an indenture or indentures supplemental hereto for the purpose of adding any
provisions to or changing in any manner or eliminating any of the provisions of
this Indenture or of modifying in any manner the rights of the Holders of
Securities and any related coupons under this Indenture; provided, however, that
no such supplemental indenture shall, without the consent of the Holder of each
Outstanding Security affected thereby:

                  (1) change the Stated Maturity of the principal of (or premium
                  or Make-Whole Amount, if any, on) or any installment of
                  principal of or interest on, any Security; or reduce the
                  principal amount thereof or the rate or amount of interest
                  thereon, or any premium or Make-Whole Amount 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 502 or the amount thereof provable
                  in bankruptcy pursuant to Section 504, or adversely affect any
                  right of repayment at the option of the Holder of any
                  Security, or change any Place of Payment where, or the
                  currency or currencies, currency unit or units or composite

                  or Make-Whole Amount or the interest thereon is payable, or
                  impair the right to institute suit for the enforcement of any
                  such payment on or after the Stated Maturity thereof (or, in
                  the case of redemption or repayment at the option of the
                  Holder, on or after the Redemption Date or the Repayment Date,
                  as the case may be), or (if Securities of such series are
                  convertible) adversely affect the right of the Holder to
                  convert any Security as provided in Article Seventeen, or
                  modify the provisions of this Indenture with respect to the
                  subordination of the Securities in a manner materially adverse
                  to the Holders; or


                                       62

<Page>

                  (2) reduce the percentage in principal amount of the
                  Outstanding Securities of any series, the consent of whose
                  Holders is required for any such supplemental indenture, or
                  the consent of whose Holders is required for any waiver with
                  respect to such series (or compliance with certain provisions
                  of this Indenture or certain defaults hereunder and their
                  consequences) provided for in this Indenture, or reduce the
                  requirements of Section 1504 for quorum or voting, or

                  (3) modify any of the provisions of this Section, Section 513
                  or Section 1009, except to increase the required percentage to
                  effect such action or to provide that certain there provisions
                  of this Indenture cannot be modified or waived without the
                  consent of the Holder of each Outstanding Security affected
                  thereby, provided, however, that this clause shall not be
                  deemed to require the consent of any Holder with respect to
                  changes in the references to "the Trustee" and concomitant
                  changes in this Section 902 and Section 1009, or the deletion
                  of this proviso, in accordance with the requirements of
                  Sections 609(b) and 901(11).

                  It shall not be necessary for any Act of Holders under this
Section 902 to approve the particular form of any proposed supplemental
indenture, but it shall be sufficient if such Act shall approve the substance
thereof.

                  A supplemental indenture which changes or eliminates any
covenant or other provision of this Indenture which has expressly been included
solely for the benefit of one or more particular series of Securities, or which
modifies the rights of the 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.

                  SECTION 903. Execution of Supplemental Indentures. In
executing, or accepting the additional trusts created by, any supplemental
indenture permitted by this Article or the modification thereby of the trusts
created by this Indenture, the Trustee shall be entitled to receive, and shall
be fully protected in relying upon, an Opinion of Counsel stating that the
execution of such supplemental indenture is authorized or permitted by this
Indenture. The Trustee may, but 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.

                  SECTION 904. Effect of Supplemental Indentures. Upon the
execution of any supplemental indenture under this Article, this Indenture shall
be modified in accordance therewith, and such supplemental indenture shall form
a part of this Indenture for all purposes; and every Holder of Securities
theretofore or thereafter authenticated and delivered hereunder and of any
coupon appertaining thereto shall be bound thereby.

                  SECTION 905. Conformity with Trust Indenture Act. Every
supplemental indenture executed pursuant to this Article shall conform to the
requirements of the Trust Indenture Act as then in effect.

                  SECTION 906. Reference in Securities to Supplemental
Indentures. Securities of any series authenticated and delivered after the
execution of any supplemental indenture pursuant to this Article may, and shall,
if required by the Trustee, bear a notation in form approved by the Trustee as
to any matter provided for in such supplemental indenture. If the


                                       63

<Page>

Company shall so determine, new Securities of any series so modified as to
conform, in the opinion of the Trustee and the Company, to any such
supplemental indenture may be prepared and executed by the Company and
authenticated and delivered by the Trustee in exchange for Outstanding
Securities of such series.

                             ARTICLE TEN - COVENANTS

otherwise specified with respect to Securities of any series pursuant to Section
301, at the option of the Company, all payments of principal may be paid by
check to the registered Holder of the Registered Security or other person
entitled thereto against surrender of such Security.

payment or conversion, where Securities of that series may be surrendered for
registration of transfer or exchange and where notices and demands to or upon
the Company in respect of the Securities of that series and this Indenture may
be served. If Securities of a series are issuable as Bearer Securities, the
Company will maintain: (A) in the Borough of Manhattan, The City of New York, an
office or agency where any Registered Securities of that series may be presented
or surrendered for payment or conversion, where any Registered Securities of
that series may be surrendered for registration of transfer, where Securities of
that series may be surrendered for exchange, where notices and demands to or
upon the Company in respect of the Securities of that series and this Indenture

series in any required city located outside the United States, as the case may
be, so long as the Securities of that series are listed on such exchange; and

for that series located outside the United States an office or agency where any
Registered Securities of that series may be surrendered for registration of
transfer, where Securities of that series may be surrendered for exchange and
where notices and demands to or upon the Company in respect of the Securities of
that series and this Indenture may be served. The Company will give prompt
written notice to the Trustee of the location, and any change in the location,
of each such office or agency. If at any time the Company shall fail to maintain
any such required office or agency or shall fail to furnish the Trustee with the
address


                                       64

thereof, such presentations, surrenders, notices and demands may be made or
served at the Corporate Trust Office of the Trustee, except that Bearer
Securities of that series and the related coupons may be presented and
surrendered for payment or conversion at the offices specified in the
Security, in London, England, and the Company hereby appoints the same as its
agent to receive such respective presentations, surrenders, notices and
demands, and the Company hereby appoints the Trustee its agent to receive all
such presentations, surrenders, notices and demands.

                  Unless otherwise specified with respect to any Securities
pursuant to Section 301, no payment of principal, premium or Make-Whole Amount
or interest on Bearer Securities shall be made at any office or agency of the
Company in the United States or by check mailed to any address in the United
States or by transfer to an account maintained with a bank located in the United
States; provided, however, that, if the Securities of a series are payable in
Dollars, payment of principal of and any premium or Make-Whole Amount and
interest on any Bearer Security shall be made at the office of the Company's
Paying Agent in the Borough of Manhattan, The City of New York, if (but only if)
payment in Dollars of the full amount of such principal, premium or Make-Whole
Amount, or interest, as the case may be, at all offices or agencies outside the
United States maintained for the purpose by the Company in accordance with this
Indenture, is illegal or effectively precluded by exchange controls or other
similar restrictions.

                  The Company may from time to time designate one or more other
offices or agencies where the Securities of one or more series may be presented
or surrendered for any or all of such purposes, and may from time to time
rescind such designations; provided, however, that no such designation or
rescission shall in any manner relieve the Company of its obligation to maintain
an office or agency in accordance with the requirements set forth above for
Securities of any series for such purposes. The Company will give prompt written
notice to the Trustee of any such designation or rescission and of any change in
the location of any such other office or agency. Unless otherwise specified with
respect to any Securities pursuant to Section 301 with respect to a series of
Securities, the Company hereby designates as a Place of Payment for each series
of Securities the office or agency of the Company in the Borough of Manhattan,
The City of New York, and initially appoints the Trustee at its Corporate Trust
Office as Paying Agent in such city and as its agent to receive all such
presentations, surrenders, notices and demands.

                  Unless otherwise specified with respect to any Securities
pursuant to Section 301, if and so long as the Securities of any series (i) are
denominated in a Foreign Currency or (ii) may be payable in a Foreign Currency,
or so long as it is required under any other provision of the Indenture, then
the Company will maintain with respect to each such series of Securities, or as
so required, at least one exchange rate agent.

                  SECTION 1003. Money for Securities Payments to Be Held in
Trust. If the Company shall at any time act as its own Paying Agent with respect
to any series of any Securities and any related coupons, it will, on or before
each due date of the principal of (and premium or Make-Whole Amount, if any), or
interest on any of the Securities of that series, segregate and hold in trust
for the benefit of the Persons entitled thereto a sum in the currency or
currencies, currency unit or units or composite currency or currencies in which
the Securities of such series are payable (except as otherwise specified
pursuant to Section 301 for the Securities of such series) sufficient to pay the
principal (and premium or Make-Whole Amount, if any) or


                                       65

<Page>

interest so becoming due until such sums shall be paid to such Persons or
otherwise disposed of as herein provided, and will promptly notify the
Trustee of its action or failure so to act.

                  Whenever the Company shall have one or more Paying Agents for
any series of Securities and any related coupons, it will, on or before each due
date of the principal of (and premium or Make-Whole Amount, if any), or interest
on any Securities of that series, deposit with a Paying Agent a sum (in the
currency or currencies, currency unit or units or composite currency or
currencies described in the preceding paragraph) sufficient to pay the principal
(and premium or Make-Whole Amount, 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 Make-Whole Amount, if any, 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.

                  The Company will cause each Paying Agent for any series of
Securities other than the Trustee to execute and deliver to the Trustee an
instrument in which such Paying Agent shall agree with the Trustee, subject to
the provisions of this Section, that such Paying Agent will

                  (1) hold all sums held by it for the payment of principal of
                  (and premium or Make-Whole Amount, if any) or interest on
                  Securities in trust for the benefit of the Persons entitled
                  thereto until such sums shall be paid to such Persons or
                  otherwise disposed of as herein provided;

                  (2) give the Trustee notice of any default by the Company (or
                  any other obligor upon the Securities) in the making of any
                  such payment of principal (and premium or Make-Whole Amount,
                  if any) or interest on the Securities of that series; and

                  (3) at any time during the continuance of any such default
                  upon the written request of the Trustee, forthwith pay to the
                  Trustee all sums so held in trust by such Paying Agent.

                  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
by Company Order 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 trusts 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 sums.

                  Except as otherwise provided in the Securities of any series,
any money deposited with the Trustee or any Paying Agent, or then held by the
Company, in trust for the payment of the principal of (and premium or Make-Whole
Amount, if any) or interest on any Security of any series and remaining
unclaimed for two years after such principal (and premium or Make-Whole Amount,
if any) or interest has become due and payable shall be paid to the Company upon
Company Request or (if then held by the Company) shall be discharged from such
trust; and the Holder of such Security shall thereafter, as an unsecured general
creditor, look only to the Company for payment of such principal of (and premium
or Make-Whole Amount, if any) or interest on any Security, without interest
thereon, and all liability of the Trustee or such Paying Agent with respect to
such trust money, and all liability of the Company as trustee thereof, shall


                                       66

<Page>

thereupon cease; provided, however, that the Trustee or such Paying Agent,
before being required to make any such repayment, may at the expense of the
Company cause to be published once, in an Authorized Newspaper, notice that such
money remains unclaimed and that, after a date specified therein, which shall
not be less than 30 days from the date of such publication, any unclaimed
balance of such money then remaining will be repaid to the Company.

                    ARTICLE ELEVEN - REDEMPTION OF SECURITIES

                  SECTION 1101. Applicability of Article. Securities of any
series which are redeemable before their Stated Maturity shall be redeemable in
accordance with their terms and (except as otherwise specified as contemplated
by Section 301 for Securities of any series) in accordance with this Article.

                  SECTION 1102. Election to Redeem; Notice to Trustee. The
election of the Company to redeem any Securities shall be evidenced by or
pursuant to a Board Resolution. In case of any redemption at the election of the
Company of less than all of the Securities of any series, the Company shall, at
least 45 days prior to the giving of the notice of redemption in Section 1104
(unless a shorter notice shall be satisfactory to the Trustee), notify the
Trustee of such Redemption Date and of the principal amount of Securities of
such series to be redeemed. In the case of any redemption of Securities prior to
the expiration of any restriction on such redemption 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 such
restriction.

                  SECTION 1103. Selection by Trustee of Securities to Be
Redeemed. If less than all the Securities of any series issued on the same day
with the same terms are to be redeemed, the particular Securities to be redeemed
shall be selected not more than 60 days prior to the Redemption Date by the
Trustee, from the Outstanding Securities of such series issued on such date with
the same terms not previously called for redemption, by such method as the
Trustee shall deem fair and appropriate and which may provide for the selection
for redemption of portions (equal to the minimum authorized denomination for
Securities of that series or any integral multiple thereof) of the principal
amount of Securities of such series of a denomination larger than the minimum
authorized denomination for Securities of that series.

                  The Trustee shall promptly notify the Company and the Security
Registrar (if other than itself) in writing of the Securities selected for
redemption and, in the case of any Securities selected for partial redemption,
the principal amount thereof to be redeemed.

                  For all purposes of this Indenture, unless the context
otherwise requires, all provisions relating to the redemption of Securities
shall relate, in the case of any Security redeemed or to be redeemed only in
part, to the portion of the principal amount of such Security which has been or
is to be redeemed.

                  SECTION 1104. Notice of Redemption. Notice of redemption shall
be given in the manner provided in Section 106, not less than 30 days nor more
than 60 days prior to the Redemption Date, unless a shorter period is specified
by the terms of such series established pursuant to Section 301, to each Holder
of Securities to be redeemed, but failure to give such notice in the manner
herein provided to the Holder of any Security designated for redemption as


                                       67

<Page>

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

                  Any notice that is mailed to the Holders of Registered
Securities in the manner herein provided shall be conclusively presumed to have
been duly given, whether or not the Holder receives the notice.

         All notices of redemption shall state:

                  (1) the Redemption Date,

                  (2) the Redemption Price, accrued interest to the Redemption
                  Date payable as provided in Section 1106, if any,

                  (3) if less than all Outstanding Securities of any series are
                  to be redeemed, the identification (and, in the case of
                  partial redemption, the principal amount) of the particular
                  Security or Securities to be redeemed,

                  (4) in case any Security is to be redeemed in part only, the
                  notice which relates to such Security shall state that on and
                  after the Redemption Date, upon surrender of such Security,
                  the holder will receive, without a charge, a new Security or
                  Securities of authorized denominations for the principal
                  amount thereof remaining unredeemed,

                  (5) that on the Redemption Date the Redemption Price and
                  accrued interest to the Redemption Date payable as provided in
                  Section 1106, if any, will become due and payable upon each
                  such Security, or the portion thereof, to be redeemed and, if
                  applicable, that interest thereon shall cease to accrue on and
                  after said date,

                  (6) the Place or Places of Payment where such Securities,
                  together in the case of Bearer Securities with all coupons
                  appertaining thereto, if any, maturing after the Redemption
                  Date, are to be surrendered for payment of the Redemption
                  Price and accrued interest, if any, or for conversion,

                  (7) that the redemption is for a sinking fund, if such is the
                  case,

                  (8) that, unless otherwise specified in such notice, Bearer
                  Securities of any series, if any, surrendered for redemption
                  must be accompanied by all coupons maturing subsequent to the
                  date fixed for redemption or the amount of any such missing
                  coupon or coupons will be deducted from the Redemption Price,
                  unless security or indemnity satisfactory to the Company, the
                  Trustee for such series and any Paying Agent is furnished,

                  (9) if Bearer Securities of any series are to be redeemed and
                  any Registered Securities of such series are not to be
                  redeemed, and if such Bearer Securities may be exchanged for
                  Registered Securities not subject to redemption on this
                  Redemption Date pursuant to Section 305 or otherwise, the last
                  date, as determined by the Company, on which such exchanges
                  may be made,


                                       68

<Page>

                  (10) the CUSIP number of such Security, if any, and

                  (11) if applicable, that a Holder of Securities who desires to
                  convert Securities for redemption must satisfy the
                  requirements for conversion contained in such Securities, the
                  then existing conversion price or rate, the place or places
                  where such Securities may be surrendered for conversion, and
                  the date and time when the option to convert shall expire.

                  Notice of redemption of Securities to be redeemed at the
election of the Company shall be given by the Company or, at the Company's
request, by the Trustee in the name and at the expense of the Company.

                  SECTION 1105. Deposit of Redemption Price. On or prior to any
Redemption Date, the Company shall deposit with the Trustee or with a Paying
Agent (or, if the Company is acting as its own Paying Agent, which it may not do
in the case of a sinking fund payment under Article Twelve, segregate and hold
in trust as provided in Section 1003) an amount of money in the currency or
currencies, currency unit or units or composite currency or currencies in which
the Securities of such series are payable (except as otherwise specified
pursuant to Section 301 for the Securities of such series) sufficient to pay on
the Redemption Date the Redemption Price of, and (except if the Redemption Date
shall be an Interest Payment Date) accrued interest on, all the Securities or
portions thereof which are to be redeemed on that date.

                  If any Securities called for redemption are converted, any
money deposited with the Trustee or with any Paying Agent or so segregated and
held in trust for the redemption of such Security shall be paid to the Company
upon Company Request or, if then held by the Company, shall be discharged from
such trust.

                  SECTION 1106. Securities Payable on Redemption Date. Notice of
redemption having been given as aforesaid, the Securities so to be redeemed
shall, on the Redemption Date, become due and payable at the Redemption Price
therein specified in the currency or currencies, currency unit or units or
composite currency or currencies in which the Securities of such series are
payable (except as otherwise specified pursuant to Section 301 for the
Securities of such series) (together with accrued interest, if any, to the
Redemption Date), and from and after such date (unless the Company shall default
in the payment of the Redemption Price and accrued interest) such Securities
shall, if the same were interest-bearing, cease to bear interest and the coupons
for such interest appertaining to any Bearer Securities so to be redeemed,
except to the extent provided below, shall be void. Upon surrender of any such
Security for redemption in accordance with said notice, together with all
coupons, if any, appertaining thereto maturing after the Redemption Date, such
Security shall be paid by the Company at the Redemption Price, together with
accrued interest, if any, to the Redemption Date; provided, however, that
installments of interest on Bearer Securities whose Stated Maturity is on or
prior to the Redemption Date shall be payable only at an office or agency
located outside the United States (except as otherwise provided in Section 1002)
and, unless otherwise specified as contemplated by Section 301, only upon
presentation and surrender of coupons for such interest; and provided further
that, except as otherwise provided with respect to Securities convertible into
the Company's Common Stock or Preferred Stock, installments of interest on
Registered Securities whose Stated Maturity is on or prior to the Redemption
Date shall be payable to the Holders of


                                       69

<Page>

such Securities, or one or more Predecessor Securities, registered as such at
the close of business on the relevant Record Dates according to their terms
and the provisions of Section 307.

                  If any Bearer Security surrendered for redemption shall not be
accompanied by all appurtenant coupons maturing after the Redemption Date, such
Security may be paid after deducting from the Redemption Price an amount equal
to the face amount of all such missing coupons, or the surrender of such missing
coupon or coupons may be waived by the Company and the Trustee if there be
furnished to them such security or indemnity as they may require to save each of
them and any Paying Agent harmless. If thereafter the Holder of such Security
shall surrender to the Trustee or any Paying Agent any such missing coupon in
respect of which a deduction shall have been made from the Redemption Price,
such Holder shall be entitled to receive the amount so deducted; provided,
however, that interest represented by coupons shall be payable only at an office
or agency located outside the United States (except as otherwise provided in
Section 1002) and, unless otherwise specified as contemplated by Section 301,
only upon presentation and surrender of those coupons.

                  If any Security called for redemption shall not be so paid
upon surrender thereof for redemption, the principal (and premium or Make-Whole
Amount, if any) shall, until paid, bear interest from the Redemption Date at the
rate borne by the Security.

                  SECTION 1107. Securities Redeemed in Part. Any Registered
Security which is to be redeemed only in part (pursuant to the provisions of
this Article or of Article Twelve) shall be surrendered at a Place of Payment
therefor (with, if the Company or the Trustee so requires, due endorsement by,
or a written instrument of transfer in form satisfactory to the Company and the
Trustee duly executed by, the Holder thereof or his attorney duly authorized in
writing) and the Company shall execute and the Trustee shall authenticate and
deliver to the Holder of such Security without service charge a new Security or
Securities of the same series, of any authorized denomination as requested by
such Holder in aggregate principal amount equal to and in exchange for the
unredeemed portion of the principal of the Security so surrendered. If a Global
Security is so surrendered, the Company shall execute and the Trustee shall
authenticate and deliver to the depository, without service charge, a new Global
Security in a denomination equal to and in exchange for the unredeemed portion
of the principal of the Global Security so surrendered.

                         ARTICLE TWELVE - SINKING FUNDS

                  SECTION 1201. Applicability of Article. The provisions of this
Article shall be applicable to any sinking fund for the retirement of Securities
of a series except as otherwise specified as contemplated by Section 301 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 such Securities of any series is herein referred to as an
"optional sinking fund payment." If provided for by the terms of any Securities
of any series, the cash amount of any mandatory sinking fund payment may be
subject to reduction as provided in Section 1202. Each sinking fund payment
shall be applied to the redemption of Securities of any series as provided for
by the terms of Securities of such series.


                                       70

<Page>

                  SECTION 1202. Satisfaction of Sinking Fund Payments with
Securities. The Company may, in satisfaction of all or any part of any mandatory
sinking fund payment with respect to the Securities of a series, (1) deliver
Outstanding Securities of such series (other than any previously called for
redemption) together in the case of any Bearer Securities of such series with
all unmatured coupons appertaining thereto and (2) apply as a credit Securities
of such 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, as
provided for by the terms of such Securities, or which have otherwise been
acquired by the Company; provided that such Securities so delivered or applied
as a credit have not been previously so credited. Such Securities shall be
received and credited for such purpose by the Trustee at the applicable
Redemption Price specified in such Securities for redemption through operation
of the sinking fund and the amount of such mandatory sinking fund payment shall
be reduced accordingly.

                  SECTION 1203. Redemption of Securities for Sinking Fund. Not
less than 60 days prior to each sinking fund payment date for Securities of any
series, the Company will deliver to the Trustee an Officers' Certificate
specifying the amount of the next ensuing mandatory sinking fund payment for
that series pursuant to the terms of that series, the portion thereof, if any,
which is to be satisfied by payment of cash in the currency or currencies,
currency unit or units or composite currency or currencies in which the
Securities of such series are payable (except as otherwise specified pursuant to
Section 301 for the Securities of such series) and the portion thereof, if any,
which is to be satisfied by delivering and crediting Securities of that series
pursuant to Section 1202, and the optional amount, if any, to be added in cash
to the next ensuing mandatory sinking fund payment, and will also deliver to the
Trustee any Securities to be so delivered and credited. If such Officers'
Certificate shall specify an optional amount to be added in cash to the next
ensuing mandatory sinking fund payment, the Company shall thereupon be obligated
to pay the amount therein specified. 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 1103 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 1104. Such notice
having been duly given, the redemption of such Securities shall be made upon the
terms and in the manner stated in Sections 1106 and 1107.

              ARTICLE THIRTEEN - REPAYMENT AT THE OPTION OF HOLDERS

                  SECTION 1301. Applicability of Article. Repayment of
Securities of any series before their Stated Maturity at the option of Holders
thereof shall be made in accordance with the terms of such Securities, if any,
and (except as otherwise specified by the terms of such series established
pursuant to Section 301) in accordance with this Article.

                  SECTION 1302. Repayment of Securities. Securities of any
series subject to repayment in whole or in part at the option of the Holders
thereof will, unless otherwise provided in the terms of such Securities, be
repaid at a price equal to the principal amount thereof, together with interest,
if any, thereon accrued to the Repayment Date specified in or pursuant to the
terms of such Securities. The Company covenants that on or prior to the
Repayment Date it will deposit with the Trustee or with a Paying Agent (or, if
the Company is acting as its own Paying Agent, segregate and hold in trust as
provided in Section 1003) an amount of money in


                                   71
<Page>

the currency or currencies, currency unit or units or composite currency or
currencies in which the Securities of such series are payable (except as
otherwise specified pursuant to Section 301 for the Securities of such
series) sufficient to pay the principal (or, if so provided by the terms of
the Securities of any series, a percentage of the principal) of, and (except
if the Repayment Date shall be an Interest Payment Date) accrued interest on,
all the Securities or portions thereof, as the case may be, to be repaid on
such date.

                  SECTION 1303. Exercise of Option. Securities of any series
subject to repayment at the option of the Holders thereof will contain an
"Option to Elect Repayment" form on the reverse of such Securities. In order for
any Security to be repaid at the option of the Holder, the Trustee must receive
at the Place of Payment therefor specified in the terms of such Security (or at
such other place or places of which the Company shall from time to time notify
the Holders of such Securities) not earlier than 60 days nor later than 30 days
prior to the Repayment Date (1) the Security so providing for such repayment
together with the "Option to Elect Repayment" form on the reverse thereof duly
completed by the Holder (or by the Holder's attorney duly authorized in writing)
or (2) a telegram, telex, facsimile transmission or a letter from a member of a
national securities exchange, or the National Association of Securities Dealers,
Inc. ("NASD"), or a commercial bank or trust company in the United States
setting forth the name of the Holder of the Security, the principal amount of
the Security, the principal amount of the Security to be repaid, the CUSIP
number, if any, or a description of the tenor and terms of the Security, a
statement that the option to elect repayment is being exercised thereby and a
guarantee that the Security to be repaid, together with the duly completed form
entitled "Option to Elect Repayment" on the reverse of the Security, will be
received by the Trustee not later than the fifth Business Day after the date of
such telegram, telex, facsimile transmission or letter; provided, however, that
such telegram, telex, facsimile transmission or letter shall only be effective
if such Security and form duly completed are received by the Trustee by such
fifth Business Day. If less than the entire principal amount of such Security is
to be repaid in accordance with the terms of such Security, the principal amount
of such Security to be repaid, in increments of the minimum denomination for
Securities of such series, and the denomination or denominations of the Security
or Securities to be issued to the Holder for the portion of the principal amount
of such Security surrendered that is not to be repaid, must be specified. The
principal amount of any Security providing for repayment at the option of the
Holder thereof may not be repaid in part if, following such repayment, the
unpaid principal amount of such Security would be less than the minimum
authorized denomination of Securities of the series of which such Security to be
repaid is a part. Except as otherwise may be provided by the terms of any
Security providing for repayment at the option of the Holder thereof, exercise
of the repayment option by the Holder shall be irrevocable unless waived by the
Company.

                  SECTION 1304. When Securities Presented for Repayment Become
Due and Payable. If Securities of any series providing for repayment at the
option of the Holders thereof shall have been surrendered as provided in this
Article and as provided by or pursuant to the terms of such Securities, such
Securities or the portions thereof, as the case may be, to be repaid shall
become due and payable and shall be paid by the Company on the Repayment Date
therein specified, and on and after such Repayment Date (unless the Company
shall default in the payment of such Securities on such Repayment Date) such
Securities shall, if the same were interest-bearing, cease to bear interest and
the coupons for such interest appertaining to any Bearer Securities so to be
repaid, except to the extent provided below, shall be void. Upon surrender of
any such Security for repayment in accordance with such provisions, together
with


                                   72
<Page>

all coupons, if any, appertaining thereto maturing after the Repayment Date,
the principal amount of such Security so to be repaid shall be paid by the
Company, together with accrued interest, if any, to the Repayment Date;
provided, however, that coupons whose Stated Maturity is on or prior to the
Repayment Date shall be payable only at an office or agency located outside
the United States (except as otherwise provided in Section 1002) and, unless
otherwise specified pursuant to Section 301, only upon presentation and
surrender of such coupons; and provided further that, in the case of
Registered Securities, installments of interest, if any, whose Stated
Maturity is on or prior to the Repayment Date shall be payable (but without
interest thereon, unless the Company shall default in the payment thereof) to
the Holders of such Securities, or one or more Predecessor Securities,
registered as such at the close of business on the relevant Record Dates
according to their terms and the provisions of Section 307.

                  If any Bearer Security surrendered for repayment shall not be
accompanied by all appurtenant coupons maturing after the Repayment Date, such
Security may be paid after deducting from the amount payable therefor as
provided in Section 1302 an amount equal to the face amount of all such missing
coupons, or the surrender of such missing coupon or coupons may be waived by the
Company and the Trustee if there be furnished to them such security or indemnity
as they may require to save each of them and any Paying Agent harmless. If
thereafter the Holder of such Security shall surrender to the Trustee or any
Paying Agent any such missing coupon in respect of which a deduction shall have
been made as provided in the preceding sentence, such Holder shall be entitled
to receive the amount so deducted; provided, however, that interest represented
by coupons shall be payable only at an office or agency located outside the
United States (except as otherwise provided in Section 1002) and, unless
otherwise specified as contemplated by Section 301, only upon presentation and
surrender of those coupons.

                  If the principal amount of any Security surrendered for
repayment shall not be so repaid upon surrender thereof, such principal amount
(together with interest, if any, thereon accrued to such Repayment Date) shall,
until paid, bear interest from the Repayment Date at the rate of interest or
Yield to Maturity (in the case of Original Issue Discount Securities) set forth
in such Security.

                  SECTION 1305. Securities Repaid in Part. Upon surrender of any
Registered Security which is to be repaid in part only, the Company shall
execute and the Trustee shall authenticate and deliver to the Holder of such
Security, without service charge and at the expense of the Company, a new
Registered Security or Securities of the same series, of any authorized
denomination specified by the Holder, in an aggregate principal amount equal to
and in exchange for the portion of the principal of such Security so surrendered
which is not to be repaid.

              ARTICLE FOURTEEN - DEFEASANCE AND COVENANT DEFEASANCE

                  SECTION 1401. Applicability of Article: Company's Option to
Effect Defeasance or Covenant Defeasance. If, pursuant to Section 301, provision
is made for either or both of (a) defeasance of the Securities of or within a
series under Section 1402 or (b) covenant defeasance of the Securities of or
within a series under Section 1403, then the provisions of such Section or
Sections, as the case may be, together with the other provisions of this Article
(with such modifications thereto as may be specified pursuant to Section 301
with respect to any Securities), shall be applicable to such Securities and any
coupons appertaining thereto, and the Company may at its option by Board
Resolution, at any time, with respect to such Securities and


                                   73
<Page>

any coupons appertaining thereto, elect to have Section 1402 (if applicable)
or Section 1403 (if applicable) be applied to such Outstanding Securities and
any coupons appertaining thereto upon compliance with the conditions set
forth below in this Article.

                  SECTION 1402. Defeasance and Discharge. Upon the Company's
exercise of the above option applicable to this Section with respect to any
Securities of or within a series, the Company shall be deemed to have been
discharged from its obligations with respect to such Outstanding Securities and
any coupons appertaining thereto on the date the conditions set forth in Section
1404 are satisfied (hereinafter, "defeasance"). For this purpose, such
defeasance means that the Company shall be deemed to have paid and discharged
the entire indebtedness represented by such Outstanding Securities and any
coupons appertaining thereto, which shall thereafter be deemed to be
"Outstanding" only for the purposes of Section 1405 and the other Sections of
this Indenture referred to in clauses (A) and (B) below, and to have satisfied
all of its other obligations under such Securities and any coupons appertaining
thereto and this Indenture insofar as such Securities and any coupons
appertaining thereto are concerned (and the Trustee, at the expense of the
Company, shall execute proper instruments acknowledging the same), except for
the following which shall survive until otherwise terminated or discharged
hereunder: (A) the rights of Holders of such Outstanding Securities and any
coupons appertaining thereto to receive, solely from the trust fund described in
Section 1404 and as more fully set forth in such Section, payments in respect of
the principal of (and premium or Make-Whole Amount, if any) and interest, if
any, on such Securities and any coupons appertaining thereto when such payments
are due, (B) the Company's obligations with respect to such Securities under
Sections 305, 306, 1002 and 1003, (C) the rights, powers, trusts, duties and
immunities of the Trustee hereunder and (D) this Article. Subject to compliance
with this Article Fourteen, the Company may exercise its option under this
Section notwithstanding the prior exercise of its option under Section 1403 with
respect to such Securities and any coupons appertaining thereto.

                  SECTION 1403. Covenant Defeasance. Upon the Company's exercise
of the above option applicable to this Section with respect to any Securities of
or within a series, the Company shall be released from its obligations under
Sections 1004 to 1009, inclusive, and, if specified pursuant to Section 301, its
obligations under any other covenant contained herein or in any indenture
supplemental hereto, with respect to such Outstanding Securities and any coupons
appertaining thereto on and after the date the conditions set forth in Section
1404 are satisfied (hereinafter, "covenant defeasance"), and such Securities and
any coupons appertaining thereto shall thereafter be deemed to be not
"Outstanding" for the purposes of any direction, waiver, consent or declaration
or Act of Holders (and the consequences of any thereof) in connection with
Sections 1004 to 1009, inclusive, or such other covenant, but shall continue to
be deemed "Outstanding" for all other purposes hereunder. For this purpose, such
covenant defeasance means that, with respect to such Outstanding Securities and
any coupons appertaining thereto, the Company may omit to comply with and shall
have no liability in respect of any term, condition or limitation set forth in
any such Section or such other covenant, whether directly or indirectly, by
reason of any reference elsewhere herein to any such Section or such other
covenant or by reason of reference in any such Section or such other covenant to
any other provision herein or in any other document and such omission to comply
shall not constitute a default or an Event of Default under Section 501(4) or
501(8) or otherwise, as the case may be, but, except as specified above, the
remainder of this Indenture and such Securities and any coupons appertaining
thereto shall be unaffected thereby.


                                   74
<Page>

                  SECTION 1404. Conditions to Defeasance or Covenant Defeasance.
The following shall be the conditions to application of Section 1402 or Section
1403 to any Outstanding Securities of or within a series and any coupons
appertaining thereto:

                  (a) The Company shall irrevocably have deposited or caused to
                  be deposited with the Trustee (or another trustee satisfying
                  the requirements of Section 607 who shall agree to comply with
                  the provisions of this Article Fourteen applicable to it) as
                  trust funds in trust for the purpose of making the following
                  payments, specifically pledged as security for, and dedicated
                  solely to, the benefit of the Holders of such Securities and
                  any coupons appertaining thereto, (1) an amount in such
                  currency, currencies or currency unit in which such Securities
                  and any coupons appertaining thereto are then specified as
                  payable at Stated Maturity, or (2) Government Obligations
                  applicable to such Securities and coupons appertaining thereto
                  (determined on the basis of the currency, currencies or
                  currency unit in which such Securities and coupons
                  appertaining thereto are then specified as payable at Stated
                  Maturity) which through the scheduled payment of principal and
                  interest in respect thereof in accordance with their terms
                  will provide, not later than the due date of any payment of
                  principal of (and premium or Make-Whole Amount, if any) and
                  interest, if any, on such Securities and any coupons
                  appertaining thereto, money in an amount, or (3) a combination
                  thereof, in any case, in an amount, sufficient, without
                  consideration of any reinvestment of such principal and
                  interest, in the opinion of a nationally recognized firm of
                  independent public accountants expressed in a written
                  certification thereof delivered to the Trustee, to pay and
                  discharge, and which shall be applied by the Trustee (or other
                  qualifying trustee) to pay and discharge, (i) the principal of
                  (and premium or Make-Whole Amount, if any) and interest, if
                  any, on such Outstanding Securities and any coupons
                  appertaining thereto on the Stated Maturity of such principal
                  or installment of principal or interest and (ii) any mandatory
                  sinking fund payments or analogous payments applicable to such
                  Outstanding Securities and any coupons appertaining thereto on
                  the day on which such payments are due and payable in
                  accordance with the terms of this Indenture and of such
                  Securities and any coupons appertaining thereto.

                  (b) Such defeasance or covenant defeasance shall not result in
                  a breach or violation of, or constitute a default under, this
                  Indenture or any other material agreement or instrument to
                  which the Company is a party or by which it is bound.

                  (c) No Event of Default or event which with notice or lapse of
                  time or both would become an Event of Default with respect to
                  such Securities and any coupons appertaining thereto shall
                  have occurred and be continuing on the date of such deposit
                  or, insofar as Sections 501(6) and 501(7) are concerned, at
                  any time during the period ending on the 91st day after the
                  date of such deposit (it being understood that this condition
                  shall not be deemed satisfied until the expiration of such
                  period).

                  (d) In the case of an election under Section 1402, the Company
                  shall have delivered to the Trustee an Opinion of Counsel
                  stating that (i) the Company has received from, or there has
                  been published by, the Internal Revenue Service a


                                   75
<Page>

                  ruling, or (ii) since the date of execution of this
                  Indenture, there has been a change in the applicable
                  Federal income tax law, in either case to the effect that,
                  and based thereon such opinion shall confirm that, the
                  Holders of such Outstanding Securities and any coupons
                  appertaining thereto will not recognize income, gain or
                  loss for Federal income tax purposes as a result of such
                  defeasance and will be subject to Federal income tax on the
                  same amounts, in the same manner and at the same times as
                  would have been the case if such defeasance had not
                  occurred.

                  (e) In the case of an election under Section 1403, the Company
                  shall have delivered to the Trustee an Opinion of Counsel to
                  the effect that the Holders of such Outstanding Securities and
                  any coupons appertaining thereto will not recognize income,
                  gain or loss for Federal income tax purposes as a result of
                  such covenant defeasance and will be subject to Federal income
                  tax on the same amounts, in the same manner and at the same
                  times as would have been the case if such covenant defeasance
                  had not occurred.

                  (f) The Company shall have delivered to the Trustee an
                  Officers' Certificate and an Opinion of Counsel, each stating
                  that all conditions precedent to the defeasance under Section
                  1402 or the covenant defeasance under Section 1403 (as the
                  case may be) have been complied with and an Opinion of Counsel
                  to the effect that either (i) as a result of a deposit
                  pursuant to subsection (a) above and the related exercise of
                  the Company's option under Section 1402 or Section 1403 (as
                  the case may be), registration is not required under the
                  Investment Company Act of 1940, as amended, by the Company,
                  with respect to the trust funds representing such deposit or
                  by the Trustee for such trust funds or (ii) all necessary
                  registrations under said Act have been effected.

                  (g) Notwithstanding any other provisions of this Section, such
                  defeasance or covenant defeasance shall be effected in
                  compliance with any additional or substitute terms, conditions
                  or limitations which may be imposed on the Company in
                  connection therewith pursuant to Section 301.

                  SECTION 1405. Deposited Money and Government Obligations to Be
Held in Trust; Other Miscellaneous Provisions. Subject to the provisions of the
last paragraph of Section 1003, all money and Government Obligations (or other
property as may be provided pursuant to Section 301) (including the proceeds
thereof) deposited with the Trustee (or other qualifying trustee, collectively
for purposes of this Section 1405, the "Trustee") pursuant to Section 1404 in
respect of any Outstanding Securities of any series and any coupons appertaining
thereto shall be held in trust and applied by the Trustee, in accordance with
the provisions of such Securities and any coupons appertaining thereto and this
Indenture, to the payment, either directly or through any Paying Agent
(including the Company acting as its own Paying Agent) as the Trustee may
determine, to the Holders of such Securities and any coupons appertaining
thereto of all sums due and to become due thereon in respect of principal (and
premium or Make-Whole Amount, if any) and interest, but such money need not be
segregated from other funds except to the extent required by law.

                  Unless otherwise specified with respect to any Security
pursuant to Section 301, if, after a deposit referred to in Section 1404(a) has
been made, (a) the Holder of a Security in


                                   76
<Page>

respect of which such deposit was made is entitled to, and does, elect
pursuant to Section 301 or the terms of such Security to receive payment in a
currency or currency unit other than that in which the deposit pursuant to
Section 1404(a) has been made in respect of such Security, or (b) a
Conversion Event occurs in respect of the currency or currency unit in which
the deposit pursuant to Section 1404(a) has been made, the indebtedness
represented by such Security and any coupons appertaining thereto shall be
deemed to have been, and will be, fully discharged and satisfied through the
payment of the principal of (and premium or Make-Whole Amount, if any), and
interest, if any, on such Security as the same becomes due out of the
proceeds yielded by converting (from time to time as specified below in the
case of any such election) the amount or other property deposited in respect
of such Security into the currency or currency unit in which such Security
becomes payable as a result of such election or Conversion Event based on the
applicable market exchange rate for such currency or currency unit in effect
on the second Business Day prior to each payment date, except, with respect
to a Conversion Event, for such currency or currency unit in effect (as
nearly as feasible) at the time of the Conversion Event.

                  The Company shall pay and indemnify the Trustee against any
tax, fee or other charge imposed on or assessed against the Government
Obligations deposited pursuant to Section 1404 or the principal and interest
received in respect thereof other than any such tax, fee or other charge which
by law is for the account of the Holders of such Outstanding Securities and any
coupons appertaining thereto.

                  Anything in this Article to the contrary notwithstanding,
subject to Section 606, the Trustee shall deliver or pay to the Company from
time to time upon Company Request any money or Government Obligations (or other
property and any proceeds therefrom) held by it as provided in Section 1404
which, in the opinion of a nationally recognized firm of independent public
accountants expressed in a written certification thereof delivered to the
Trustee, are in excess of the amount thereof which would then be required to be
deposited to effect a defeasance or covenant defeasance, as applicable, in
accordance with this Article.

               ARTICLE FIFTEEN - MEETINGS OF HOLDERS OF SECURITIES

                  SECTION 1501. Purposes for Which Meetings May Be Called. A
meeting of Holders of Securities of any series may be called at any time and

                  1501, to be held at such time and at such place as the Trustee

                  in Section 106, not less than 20 nor more than 180 days prior
                  to the date fixed for the meeting.

                  (b) In case at any time the Company, pursuant to a Board
                  Resolution, or the Holders of at least 25% in principal amount
                  of the Outstanding Securities of any series shall have
                  requested the Trustee to call a meeting of the Holders of
                  Securities of such series for any purpose specified in Section
                  1501, by written request setting forth in reasonable detail

                  request or shall not thereafter proceed to cause the meeting
                  to be held as provided herein, then the Company or the Holders

the request of Holders of Securities of such series, be dissolved. In any other
case the meeting may be adjourned for a period of not less than 10 days as
determined by the chairman of the meeting prior to the adjournment of such
meeting. In the absence of a quorum at the reconvening of any such adjourned
meeting, such adjourned meeting may be further adjourned for a period of not

except as limited by the proviso to Section 902, any resolution with respect to
any request, demand, authorization, direction, notice, consent, waiver or other
action which this Indenture


                                   78
<Page>

expressly provides may be made, given or taken by the Holders of a specified
percentage, which is less than a majority, in principal amount of the
Outstanding Securities of a series may be adopted at a meeting or an
adjourned meeting duly reconvened and at which a quorum is present as
aforesaid by the affirmative vote of the Holders of such specified percentage
in principal amount of the Outstanding Securities of that series.

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

                  Notwithstanding the foregoing provisions of this Section 1504,
if any action is to be taken at a meeting of Holders of Securities of any series
with respect to any request, demand, authorization, direction, notice, consent,
waiver or other action that this Indenture expressly provides may be made, given
or taken by the Holders of a specified percentage in principal amount of all
Outstanding Securities affected thereby, or of the Holders of such series and
one or more additional series:

                  (i) there shall be no minimum quorum requirement for such
                  meeting; and

                  (ii) the principal amount of the Outstanding Securities of
                  such series that vote in favor of such request, demand,
                  authorization, direction, notice, consent, waiver or other
                  action shall be taken into account in determining whether such
                  request, demand, authorization, direction, notice, consent,
                  waiver or other action has been made, given or taken under
                  this Indenture.

         SECTION 1505. Determination of Voting Rights; Conduct and Adjournment
of Meetings.

                  (a) Notwithstanding any provisions of this Indenture, the
                  Trustee may make such reasonable regulations as it may deem
                  advisable for any meeting of Holders of Securities of a series
                  in regard to proof of the holding of Securities of such series
                  and of the appointment of proxies and in regard to the
                  appointment and duties of inspectors of votes, the submission
                  and examination of proxies, certificates and other evidence of
                  the right to vote, and such other matters concerning the
                  conduct of the meeting as it shall deem appropriate. Except as
                  otherwise permitted or required by any such regulations, the
                  holding of Securities shall be proved in the manner specified
                  in Section 104 and the appointment of any proxy shall be
                  proved in the manner specified in Section 104 or by having the
                  signature of the Person executing the proxy witnessed or
                  guaranteed by any trust company, bank or banker authorized by
                  Section 104 to certify to the holding of Bearer Securities.
                  Such regulations may provide that written instruments
                  appointing proxies, regular on their face, may be presumed
                  valid and genuine without the proof specified in Section 104
                  or other proof.

                  (b) The Trustee shall, by an instrument in writing appoint a
                  temporary chairman of the meeting, unless the meeting shall
                  have been called by the Company or by Holders of Securities as
                  provided in Section 1502(b), in which


                                   79
<Page>

                  case the Company or the Holders of Securities of the series
                  calling the meeting, as the case may be, shall in like
                  manner appoint a temporary chairman. A permanent chairman
                  and a permanent secretary of the meeting shall be elected
                  by vote of the Persons entitled to vote a majority in
                  principal amount of the Outstanding Securities of such
                  series represented at the meeting.

                  (c) At any meeting each Holder of a Security of such series or
                  proxy shall be entitled to one vote for each $1,000 principal
                  amount of the Outstanding Securities of such series held or
                  represented by him; provided, however, that no vote shall be
                  cast or counted at any meeting in respect of any Security
                  challenged as not Outstanding and ruled by the chairman of the
                  meeting to be not Outstanding. The chairman of the meeting
                  shall have no right to vote, except as a Holder of a Security
                  of such series or proxy.

                  (d) Any meeting of Holders of Securities of any series duly
                  called pursuant to Section 1502 at which a quorum is present
                  may be adjourned from time to time by Persons entitled to vote
                  a majority in principal amount of the Outstanding Securities
                  of such series represented at the meeting, and the meeting may
                  be held as so adjourned without further notice.

                  SECTION 1506. Counting Votes and Recording Action of Meetings.
The vote upon any resolution submitted to any meeting of Holders of Securities
of any series shall be by written ballots on which shall be subscribed the
signatures of the Holders of Securities of such series or of their
representatives by proxy and the principal amounts and serial numbers of the
Outstanding Securities of such series held or represented by them. The permanent
chairman of the meeting shall appoint two inspectors of votes who shall count
all votes cast at the meeting for or against any resolution and who shall make
and file with the secretary of the meeting their verified written reports in
duplicate of all votes cast at the meeting. A record, at least in duplicate, of
the proceedings of each meeting of Holders of Securities of any Series shall be
prepared by the secretary of the meeting and there shall be attached to said
record the original reports of the inspectors of votes on any vote by ballot
taken thereat and affidavits by one or more persons having knowledge of the
fact, setting forth a copy of the notice of the meeting and showing that said
notice was given as provided in Section 1502 and, if applicable, Section 1504.
Each copy shall be signed and verified by the affidavits of the permanent
chairman and secretary of the meeting and one such copy shall be delivered to
the Company and another to the Trustee to be preserved by the Trustee, the
latter to have attached thereto the ballots voted at the meeting. Any record so
signed and verified shall be conclusive evidence of the matters therein stated.

                  ARTICLE SIXTEEN - SUBORDINATION OF SECURITIES

                  SECTION 1601. Agreement to Subordinate. Notwithstanding
anything in this Indenture to the contrary (other than Article Four of this
Indenture), the Company covenants and agrees, and each Holder of a Security, by
his acceptance thereof, likewise covenants and agrees, that, to the extent and
in the manner hereinafter set forth in this Article, the Indebtedness
represented by the Securities and the payment of any Obligations with respect to
each and all of the Securities are hereby expressly made subordinate and subject
in right of payment to the prior payment in full of all Senior Debt.


                                   80
<Page>

                  SECTION 1602. Payment Over of Proceeds upon Dissolution, Etc.
In the event of (a) any insolvency or bankruptcy case or Proceeding, or any
receivership, liquidation, reorganization or other similar case or Proceeding in
connection therewith, relative to the Company or to its creditors, as such, or
to its assets, or (b) any liquidation, dissolution or other winding up of the
Company, whether voluntary or involuntary and whether or not involving
insolvency or bankruptcy, or (c) any assignment for the benefit of creditors or
any other marshaling of assets and liabilities of the Company, then and in any
such event specified in (a), (b) or (c) above (each such event, if any, herein
sometimes referred to as a "Proceeding") (1) the holders of Senior Debt shall
first be entitled to receive payment in full of all Obligations due or to become
due on or in respect of all Senior Debt, or provision shall be made for such
payment in cash or cash equivalents or otherwise in a manner satisfactory to the
holders of Senior Debt, before the Holders of the Securities are entitled to
receive any payment or distribution on account of principal of or premium, if
any, or interest on or other Obligations in respect of the Securities or on
account of any purchase, redemption or other acquisition of Securities by the
Company or any Subsidiary (individually and collectively, a "Securities
Payment"), and (2) any payment or distribution of assets of the Company of any
kind or character, whether in cash, property or securities (other than Capital
Stock or securities of the Company as reorganized or readjusted, or securities
of the Company or any other corporation provided for by a plan of reorganization
or readjustment, the payment of which is subordinate, at least to the extent
provided in this Article Sixteen with respect to the Securities, to the payment
in full, without diminution or modification by such plan, of all Senior Debt),
to which the Holders would be entitled except for the provisions of this Article
Sixteen, shall be paid by the liquidating trustee or agent or other person
making such a payment or distribution, directly to the holders of Senior Debt)
(or their representative(s) or trustee(s) acting on their behalf), ratably
according to the aggregate amounts remaining unpaid on account of the principal
of or interest on and other amounts due on the Senior Debt held or represented
by each, to the extent necessary to make payment in full of all Senior Debt
remaining unpaid, after giving effect to any concurrent payment or distribution
to the holders of such Senior Debt.

                  In the event that, notwithstanding the foregoing provisions of
this Section 1601, the Trustee or the Holder of any Security shall have received
any payment or distribution of assets of the Company of any kind or character,
whether in cash, property or securities (other than Capital Stock or securities
of the Company as reorganized or readjusted, or securities of the Company or any
other corporation provided for by a plan of reorganization or readjustment, the
payment of which is subordinate, at least to the extent provided in this Article
with respect to the Securities, to the payment in full, without diminution or
modification by such plan, of Senior Debt), before all Senior Debt is paid in
full or payment thereof provided for in cash or cash equivalents or otherwise in
a manner satisfactory to the holders of Senior Debt, such payment or
distribution shall be held in trust for the benefit of, and be paid over to, the
holders of the Senior Debt remaining unpaid (or their representative(s) or
trustee(s) acting on their behalf), ratably as aforesaid, for application to the
payment of such Senior Debt until such Senior Debt shall have been paid in full,
after giving effect to any concurrent payment or distribution to the holders of
such Senior Debt.

                  The consolidation of the Company with, or the merger of the
Company into, another Person or the liquidation or dissolution of the Company
following the conveyance or transfer of all or substantially all of its
properties and assets as an entirety to another Person upon the terms and
conditions set forth in Article Eight shall not be deemed a Proceeding for the

                                       81
<Page>

purposes of this Section 1602 if the Person formed by such consolidation or
into which the Company is merged or the Person which acquires by conveyance
or transfer such properties and assets as an entirety, as the case may be,
shall, as a part of such consolidation, merger, conveyance or transfer,
comply with the conditions set forth in Article Eight.

                  SECTION 1603. No Payment When Senior Debt in Default. Anything
in this Indenture to the contrary notwithstanding, no payment on account of
principal of or redemption of, interest on or other amounts due on the
Securities, and no redemption, purchase, or other acquisition of the Securities,
shall be made by or on behalf of the Company (i) unless full payment of amounts
then due for principal and interest and of all other obligations then due on all
Senior Debt been made or duly provided for pursuant to the terms of the
instrument governing such Senior Debt, (ii) if, at the time of such payment,
redemption, purchase or other acquisition, or immediately after giving effect
thereto, there shall exist under any Senior Debt, or any agreement pursuant to
which any Senior Debt is issued, any default, which default shall not have been
cured or waived and which default shall have resulted in the full amount of such
Senior Debt being declared due and payable or (iii) if, at the time of such
payment, redemption, purchase or other acquisition, the Trustee shall have
received written notice from the holder or holders of any Senior Debt or their
representative or representatives (a "Payment Blockage Notice") that there
exists under such Senior Debt, or any agreement pursuant to which such Senior
Debt is issued, any default, which default shall not have been cured or waived,
permitting the holders thereof to declare the full amount of such Senior Debt
due and payable, but only for the period (the "Payment Blockage Period")
commencing on the date of receipt of the Payment Blockage Notice and ending
(unless earlier terminated by notice given to the Trustee by the Holders of such
Senior Debt) on the earlier of (A) the date on which such event of default shall
have been cured or waived or (B) 180 days from the receipt of the Payment
Blockage Notice. Upon termination of a Payment Blockage Period, payments on
account of principal of or interest on the Securities and redemptions, purchases
or other acquisitions may be made by or on behalf of the Company.
Notwithstanding anything herein to the contrary, (A) only one Payment Blockage
Notice may be given during any period of 360 consecutive days with respect to
the same event of default and any other events of default on the same issue of
Senior Debt existing and known to the person giving such notice at the time of
such notice and (B) no new Payment Blockage Period may be commenced by the
holder or holders of the same issue of Senior Debt or their representative or
representatives during any period of 360 consecutive days unless all events of
default which were the object of the immediately preceding Payment Blockage
Notice, and any other event of default on the same issue of Senior Debt existing
and known to the person giving such notice at the time of such notice, have been
cured or waived.

                  In the event that, notwithstanding the provisions of this
Section 1603, payments are made by or on behalf of the Company in contravention
of the provisions of this Section 1603, such payments shall be held by the
Trustee, any Paying Agent or the Holders, as applicable, in trust for the
benefit of, and shall be paid over to and delivered to, the holders of Senior
Debt or their representative or the trustee under the indenture or other
agreement (if any), pursuant to which any instruments evidencing any Senior Debt
may have been issued, as their respective interests may appear, for application
to the payment of all Senior Debt remaining unpaid to the extent necessary to
pay all Senior Debt in full in accordance with the terms of such Senior Debt,
after giving effect to any concurrent payment or distribution to or for the
holders of Senior Debt.


                                       82
<Page>

                  The provisions of this Section shall not apply to any payment
with respect to which Section 1602 would be applicable.

                  SECTION 1604. Reliance by Senior Debt on Subordination
Provisions. Each Holder of any Security by his acceptance thereof acknowledges
and agrees that the foregoing subordination provisions are, and are intended to
be, an inducement and a consideration for each holder of any Senior Debt,
whether such Senior Debt was created or acquired before or after the issuance of
the Securities, to acquire and continue to hold, or to continue to hold, such
Senior Debt, and such holder of Senior Debt shall be deemed conclusively to have
relied on such subordination provisions in acquiring and continuing to hold or
in continuing to hold such Senior Debt.

                  SECTION 1605. Subrogation to Rights of Holders of Senior Debt.
Subject to the payment in full of all Obligations due or to become due on or in
respect of Senior Debt, or the provision for such payment in cash or cash
equivalents or otherwise in a manner satisfactory to the holders of Senior Debt,
the Holders of the Securities shall be subrogated to the extent of the payments
or distributions made to the holders of such Senior Debt pursuant to the
provisions of this Article Sixteen to the rights of the holders of such Senior
Debt to receive payments and distributions of cash, property and securities
applicable to the Senior Debt until the principal of and premium, if any, and
interest on the Securities shall be paid in full. For purposes of such
subrogation, no payments or distributions to the holders of the Senior Debt of
any cash, property or securities to which the Holders of the Securities or the
Trustee would be entitled except for the provisions of this Article Sixteen, and
no payments over pursuant to the provisions of this Article Sixteen to the
holders of Senior Debt by Holders of the Securities or the Trustee, shall, as
among the Company, its creditors other than holders of Senior Debt and the
Holders of the Securities, be deemed to be a payment or distribution by the
Company to or on account of the Senior Debt.

                  SECTION 1606. Provisions Solely to Define Relative Rights. The
provisions of this Article Sixteen are and are intended solely for the purpose
of defining the relative rights of the Holders of the Securities on the one hand
and the holders of Senior Debt on the other hand. Nothing contained in this
Article or elsewhere in this Indenture or in the Securities is intended to or
shall (a) impair, as among the Company, its creditors other than holders of
Senior Debt and the Holders of the Securities, the obligation of the Company,
which is absolute and unconditional (and which, subject to the rights under this
Article Sixteen of the holders of Senior Debt, is intended to rank equally with
all other general obligations of the Company), to pay to the Holders of the
Securities the principal of and premium, if any, and interest on the Securities
as and when the same shall become due and payable in accordance with their
terms; or (b) affect the relative rights against the Company of the Holders of
the Securities and creditors of the Company other than the holders of Senior
Debt; or (c) prevent the Trustee or the Holder of any Security from exercising
all remedies otherwise permitted by applicable law upon default under this
Indenture, subject to the rights, if any, under this Article of the holders of
Senior Debt to receive cash, property and securities otherwise payable or
deliverable to the Trustee or such Holder.

                  SECTION 1607. Trustee to Effectuate Subordination. Each Holder
of a Security by his acceptance thereof authorizes and directs the Trustee on
his behalf to take such action as may be necessary or appropriate to effectuate,
as between the Holders of the Securities and the holders of Senior Debt, the
subordination provided in this Article Sixteen and appoints the


                                       83
<Page>

Trustee his attorney-in-fact for any and all such purposes, including, in the
event of any dissolution, winding up or liquidation or reorganization under
any applicable bankruptcy law of the Company (whether in bankruptcy,
insolvency or receivership Proceedings or otherwise), the timely filing of a
claim for the unpaid balance of such Holder's Securities in the form required
in such Proceedings and the causing of such claim to be approved. If the
Trustee does not file a claim or proof of debt in the form required in such
Proceedings prior to 30 days before the expiration of the time to file such
claims or proofs, then the holders of Senior Debt, jointly, or their
representatives shall have the right to file an appropriate claim for and on
behalf of the Holders and to demand, sue for, collect, receive and receipt
for the payments and distributions in respect of the Securities which are
required to be paid or delivered to the holders of Senior Debt as provided in
this Article Sixteen and to take all such other action in the name of the
Holders or otherwise, as such holder of Senior Debt or representative thereof
may determine to be necessary or appropriate for the enforcement of the
provisions of this Article Sixteen.

                  SECTION 1608. No Waiver of Subordination Provisions. No right
of any present or future holder of any Senior Debt to enforce subordination as
herein provided shall at any time in any way be prejudiced or impaired by any
act or failure to act on the part of the Company or by any act or failure to
act, in good faith, by any such holder or any representative or trustee
therefor, or by any non-compliance by the Company with the terms, provisions and
covenants of this Indenture, regardless of any knowledge thereof any such holder
may have or be otherwise charged with.

                  Without in any way limiting the generality of the foregoing
paragraph, the holders of Senior Debt may, at any time from time to time,
without the consent of or notice to the Trustee or the Holders of the
Securities, without incurring responsibility to the Holders of the Securities
and without impairing or releasing the subordination provided in this Article
Sixteen or the obligations hereunder of the Holders of the Securities to the
holders of Senior Debt, do any one or more of the following: (i) change the
manner, place or terms of payment or extend the time of payment of, or renew or
alter, Senior Debt, or otherwise amend or supplement in any manner Senior Debt
or any instrument evidencing the same or any agreement under which Senior Debt
is outstanding; (ii) sell, exchange, release or otherwise deal with any property
pledged, mortgaged or otherwise securing Senior Debt; (iii) release any Person
liable in any manner for the collection of Senior Debt and settle or compromise
Senior Debt (which, to the extent so settled and compromised, shall be deemed to
have been paid in full for all purposes hereof); (iv) apply any amounts received
to any liability of the Company owing to holders of Senior Debt; and (v)
exercise or refrain from exercising any rights against the Company and any other
Person.

                  SECTION 1609. Notice to Trustee. The Company shall give prompt
written notice to the Trustee of any default or event of default with respect to
any Senior Debt or of any fact known to the Company which would prohibit the
making of any payment to or by the Trustee in respect of the Securities pursuant
to the provisions of this Article Sixteen. Notwithstanding the provisions of
this Article Sixteen or any other provision of this Indenture, the Trustee shall
not be charged with knowledge of the existence of any facts which would prohibit
the making of any payment to or by the Trustee in respect of the Securities,
unless and until the Trustee shall have received written notice thereof from the
Company or a holder of Senior Debt or from any representative or trustee acting
on their behalf; and, prior to the receipt of any such written notice, the
Trustee, subject to the provisions of Section 612, shall be entitled


                                       84
<Page>

in all respects to assume that no such facts exist; provided, however, that
if the Trustee shall not have received the notice provided for in this
Section at least three Business Days prior to the date upon which by the
terms hereof any money may become payable for any purpose (including, without
limitation, the payment of the principal of and premium, if any, or interest
on any Security), then, anything herein contained to the contrary
notwithstanding, the Trustee shall have full power and authority to receive
such money and to apply the same to the purpose for which such money was
received and shall not be affected by any notice to the contrary which may be
received by it within three Business Days prior to such date. Nothing
contained in this Article Sixteen or any other Article of this Indenture or
in any of the Securities shall prevent (a) the Company, at any time except
during the pendency of any Proceeding, or under the conditions described in
Section 1603, from making payments at any time in respect of the Securities,
or (b) the application by the Trustee of any money deposited with it
hereunder to the payment of or on account of the Securities, or the retention
thereof by any Holder, if the Trustee did not have notice, as provided in
this Section 1609, that such payment would have been prohibited by the
provisions of this Article Sixteen.

                  Subject to the provisions of Section 612, the Trustee shall be
entitled to rely on the delivery to it of a written notice by a Person
representing himself to be a holder of Senior Debt (or a representative or
trustee therefor) to establish that such notice has been given by a holder of
Senior Debt (or a trustee therefor). In the event that the Trustee determines in
good faith that further evidence is required with respect to the right of any
Person as a holder of Senior Debt to participate in any payment or distribution
pursuant to this Article Sixteen, the Trustee may request such Person to furnish
evidence to the reasonable satisfaction of the Trustee as to the amount of
Senior Debt held by such Person, the extent to which such Person is entitled to
participate in such payment or distribution and any other facts pertinent to the
rights of such Person under this Article Sixteen, and if such evidence is not
furnished, the Trustee may defer any payment to such Person pending judicial
determination as to the right of such Person to receive such payment.

                  SECTION 1610. Reliance on Judicial Order or Certificate of
Liquidating Agent. Upon any payment or distribution of assets of the Company
referred to in this Article Sixteen, the Trustee, subject to the provisions of
Section 612, and the Holders of the Securities shall be entitled to rely upon
any order or decree entered by any court of competent jurisdiction in which any
Proceeding is pending, or a certificate of the trustee in bankruptcy, receiver,
liquidating trustee, custodian, assignee for the benefit of creditors, agent or
other Person making such payment or distribution, delivered to the Trustee or to
the Holders of Securities, for the purpose of ascertaining the Persons entitled
to participate in such payment or distribution, the holders of the Senior Debt
and other indebtedness of the Company, the amount thereof or payable thereon,
the amount or amounts paid or distributed thereon and all other facts pertinent
thereto or to this Article.

                  SECTION 1611. Trustee Not Fiduciary for Holders of Senior
Debt. The Trustee shall not be deemed to owe any fiduciary duty to the holders
of Senior Debt. Nothing contained in this Article Sixteen or elsewhere in this
Indenture, or in any of the Securities, shall prevent the application by the
Trustee of any moneys which were deposited with it hereunder, prior to its
receipt of written notice of facts which would prohibit such application, for
the purpose of the payment of or on account of the principal of or interest on,
the Securities unless, prior to the date


                                       85
<Page>

on which such application is made by the Trustee, the Trustee shall be
charged with notice under Section 1609 hereof of the facts which would
prohibit the making of such application.

                  SECTION 1612. Rights of Trustee as Holder of Senior Debt;
Preservation of Trustee's Rights. The Trustee in its individual capacity shall
be entitled to all the rights set forth in this Article Sixteen with respect to
any Senior Debt which may at any time be held by it, to the same extent as any
other holder of Senior Debt, and nothing in this Indenture shall deprive the
Trustee of any of its rights as such holder. Nothing in this Article shall apply
to claims of, or payments to, the Trustee under or pursuant to Section 606.

                  SECTION 1613. Article Applicable to Paying Agents. In case at
any time any Paying Agent other than the Trustee shall have been appointed by
the Company and be then acting hereunder, the term "Trustee" as used in this
Article Sixteen shall in such case (unless the context otherwise requires) be
construed as extending to and including such Paying Agent within its meaning as
fully for all intents and purposes as if such Paying Agent were named in this
Article in addition to or in place of the Trustee; provided, however, that
Section 1612 shall not apply to the Company or any Affiliate of the Company if
it or such Affiliate acts as Paying Agent.

                  ARTICLE SEVENTEEN - CONVERSION OF SECURITIES

                  SECTION 1701. Applicability of Article; Conversion Privilege
and Conversion Price. Securities of any series which are convertible shall be
convertible in accordance with their terms and (except as otherwise specified as
contemplated by Section 301 for Securities of any series) in accordance with
this Article Seventeen. Subject to and upon compliance with the provisions of
this Article Seventeen, at any time during the period specified in the
Securities, at the option of the Holder thereof, any Security or any portion of
the principal amount thereof which is $1,000 or an integral multiple of $1,000
may be converted at the principal amount thereof, or of such portion thereof,
into fully paid and nonassessable shares (calculated as to each conversion to
the nearest 1/100 of a share) of Common Stock of the Company, at the Conversion
Price, determined as hereinafter provided, in effect at the time of conversion.
In case a Security or portion thereof is called for redemption, such conversion
right in respect of the Security or portion so called shall expire at the close
of business on the Business Day immediately preceding the Redemption Date,
unless the Company defaults in making the payment due upon redemption, in which
case such conversion right shall terminate on the date such default is cured.

                  The price at which shares of Common Stock shall be delivered
upon conversion (herein called the "Conversion Price") of Securities of any
series shall be specified in such Securities. The Conversion Price shall be
adjusted in certain instances as provided in Section 1704.

                  In case the Company shall, by dividend or otherwise, declare
or make a distribution on its Common Stock referred to in paragraph (4) of
Section 1704, the Holder of each Security, upon the conversion thereof pursuant
to this Article Seventeen subsequent to the close of business on the date fixed
for the determination of stockholders entitled to receive such distribution and
prior to the effectiveness of the Conversion Price adjustment in respect of such
distribution pursuant to paragraph (4) of Section 1704, shall be entitled to
receive for each share of Common Stock into which such Security is converted,
the portion of the evidence of


                                       86

indebtedness, shares of Capital Stock or assets so distributed applicable to
one share of Common Stock; provided, however, that, at the election of the
Company (whose election shall be evidenced by a Board Resolution filed with
the Trustee) with respect to all Holders so converting, the Company may, in
lieu of distributing to such Holder any portion of such distribution not
consisting of cash or securities of the Company, pay such Holder an amount in
cash equal to the fair market value thereof (as determined in good faith by
the Board of Directors, whose determination shall be conclusive and described
in a Board Resolution filed with the Trustee). If any conversion of a
Security entitled to the benefits described in the immediately preceding
sentence occurs prior to the payment date for a distribution to holders of
Common Stock which the Holder of the Security so converted is entitled to
receive in accordance with the immediately preceding sentence, the Company
may elect (such election to be evidenced by a Board Resolution filed with the
Trustee) to distribute to such Holder a due bill for the evidences of
indebtedness, shares of Capital Stock or assets to which such Holder is so
entitled, provided that such due bill (i) meets any applicable requirements
of the principal national securities exchange or other market on which the
Common Stock is then traded, and (ii) requires payment or delivery of such
evidences of indebtedness or assets no later than the date of payment or
delivery thereof to holders of Common Stock receiving such distribution.

                  SECTION 1702. Exercise of Conversion Privilege. In order to
exercise the conversion privilege, the Holder of any Security to be converted
shall surrender such Security, duly endorsed or assigned to the Company or in
blank, at any office or agency maintained by the Company pursuant to Section
1002, accompanied by written notice to the Company at such office or agency that
the Holder elects to convert such Security or, if less than the entire principal
amount thereof is to be converted, the portion thereof to be converted and shall
comply with any additional requirements set forth in such Security. Securities
surrendered for conversion during the period from the close of business on any
Regular Record Date next preceding any Interest Payment Date to the opening of
business on such Interest Payment Date shall (except for Securities the Maturity
of which is prior to such Interest Payment Date) be accompanied by payment in
New York Clearing House funds or other funds acceptable to the Company of an
amount equal to the interest payable on such Interest Payment Date on the
principal amount of Securities being surrendered for conversion and such
interest shall be paid on such Interest Payment Date as provided in Section 307.
Except as provided in the preceding sentence, no payment or adjustment shall be
made upon any conversion on account of any interest accrued on the Securities
surrendered for conversion or on account of any dividends on the Common Stock
issued upon conversion.

                  The Company's delivery to the Holder of the fixed number of
shares of the Common Stock of the Company (and any cash in lieu of any
fractional share of Common Stock) into which the Security is convertible shall
be deemed to satisfy the Company's obligation to pay the principal amount of the
Security and all accrued interest and original issue discount that has not
previously been paid. The shares of Common Stock of the Company so delivered
shall be treated as issued first in payment of accrued interest and original
issue discount and then in payment of principal. Thus, accrued interest and
original issue discount shall be treated as paid, rather than canceled,
extinguished or forfeited.

                  Securities shall be deemed to have been converted immediately
prior to the close of business on the day of surrender of such Securities for
conversion in accordance with the foregoing provisions, and at such time the
rights of the Holders of such Securities as Holders


                                       87
<Page>

shall cease, and the Person or Persons entitled to receive the Common Stock
issuable upon conversion shall be treated for all purposes as the record
holder or holders of such Common Stock at such time. As promptly as
practicable on or after the conversion date, the Company shall issue and
shall deliver at such office or agency a certificate or certificates for the
number of full shares of Common Stock issuable upon conversion, together with
payment in lieu of any fraction of a share, as provided in Section 1703.

                  In the case of any Security which is converted in part only,
as promptly as practicable on or after the conversion date the Company shall
execute and the Trustee shall authenticate and make available for delivery to
the Holder thereof (or the Depositary in the case of a Global Security), at the
expense of the Company, a new Security or Securities, of authorized
denominations in aggregate principal amount equal to the unconverted portion of
the principal amount of such Security.

                  SECTION 1703. Fractions of Shares. No fractional shares of
Common Stock shall be issued upon conversion of Securities. If more than one
Security shall be surrendered for conversion at one time by the same Holder, the
number of full shares of Common Stock which shall be issuable upon conversion
thereof shall be computed on the basis of the aggregate principal amount of the
Securities (or specified portions thereof) so surrendered. Instead of any
fractional share of Common Stock which would otherwise be issuable upon
conversion of any Security or Securities (or specified portions thereof), the
Company shall pay a cash adjustment (rounded to the nearest cent) in respect of
such fraction in an amount equal to the same fraction of the Closing Price per
share of the Common Stock on the day of conversion (or, if such day is not a
Trading Day, on the Trading Day immediately preceding such day).

                  SECTION 1704. Adjustment of Conversion Price. The Conversion
Price shall be subject to adjustment from time to time as follows:

                  (1) If the Company pays or makes a dividend or other
                  distribution (a) on its Common Stock exclusively in Common
                  Stock or (b) on any other class of Capital Stock of the
                  Company, which dividend or distribution includes Common Stock
                  of the Company, the Conversion Price in effect at the opening
                  of business on the day following the date fixed for the
                  determination of stockholders entitled to receive such
                  dividend or other distribution (the "Dividend Record Date")
                  shall be reduced by multiplying such Conversion Price by a
                  fraction of which the numerator shall be the number of shares
                  of Common Stock of the Company outstanding at the close of
                  business on the Dividend Record Date and the denominator shall
                  be the sum of such number of shares and the total number of
                  shares constituting such dividend or other distribution. Such
                  reduction shall become effective immediately after the opening
                  of business on the day following the date fixed for such
                  determination. For the purposes of this paragraph (1), the
                  number of shares of Common Stock of the Company at any time
                  outstanding shall not include shares held in the treasury of
                  the Company, but shall include shares issuable in respect of
                  scrip certificates issued in lieu of fractions of shares of
                  Common Stock. The Company shall not pay any dividend or make
                  any distribution on shares of Common Stock held in the
                  treasury of the Company.


                                       88
<Page>

                  (2) Subject to paragraph (6) of this Section, if the Company
                  pays or makes a dividend or other distribution on its Common
                  Stock consisting exclusively of Short Term Rights (as defined
                  below), or otherwise issues Short Term Rights to all holders
                  of its Common Stock, the Conversion Price in effect at the
                  opening of business on the day following the record date for
                  the determination of holders of Common Stock entitled to
                  receive such Short Term Rights (the "Rights Record Date")
                  shall be reduced by multiplying such Conversion Price by a
                  fraction of which the numerator shall be the number of shares
                  of Common Stock of the Company outstanding at the close of
                  business on the Rights Record Date plus the number of shares
                  of Common Stock of the Company which the aggregate of the
                  offering price of the total number of shares of Common Stock
                  so offered for subscription or purchase would purchase at such
                  current market price and the denominator shall be the number
                  of shares of Common Stock of the Company outstanding at the
                  close of business on the Rights Record Date plus the number of
                  shares of Common Stock so offered for subscription or
                  purchase. Such reduction shall become effective immediately
                  after the opening of business on the day following the Rights
                  Record Date. For the purposes of this paragraph (2), the
                  number of shares of Common Stock of the Company at any time
                  outstanding shall not include shares held in the treasury of
                  the Company, but shall include shares issuable in respect of
                  scrip certificates issued in lieu of fractions of shares of
                  Common Stock of the Company. The Company shall not issue any
                  rights, options or warrants in respect of shares of its Common
                  Stock held in the treasury of the Company. When used in this
                  Section 1704, the term "Short Term Rights" shall mean rights,
                  warrants or options entitling the holders thereof (for a
                  period commencing no earlier than the Rights Record Date and
                  expiring not more than 45 days after the Rights Record Date)
                  to subscribe for or purchase shares of Common Stock of the
                  Company at a price per share less than the current market
                  price per share (determined as provided in paragraph (7) of
                  this Section 1704) of the Common Stock of the Company on the
                  Rights Record Date.

                  (3) In case outstanding shares of Common Stock of the Company
                  shall be subdivided into a greater number of shares of Common
                  Stock, the Conversion Price in effect at the opening of
                  business on the day following the day upon which such
                  subdivision becomes effective shall be proportionately
                  reduced, and, conversely, in case outstanding shares of Common
                  Stock of the Company shall be combined into a smaller number
                  of shares of Common Stock, the Conversion Price in effect at
                  the opening of business on the day following the day upon
                  which such combination becomes effective shall be
                  proportionately increased, such reduction or increase, as the
                  case may be, to become effective immediately after the opening
                  of business on the day following the day upon which such
                  subdivision or combination becomes effective.

                  (4) Subject to the last sentence of this paragraph (4) of this
                  Section, if the Company, by dividend or otherwise, (a)
                  distributes to all holders of its Common Stock evidences of
                  its indebtedness, shares of any class of Capital Stock of the
                  Company or other assets (other than cash dividends out of
                  current or retained earnings), or (b) distributes to
                  substantially all holders of Common Stock rights or warrants
                  to subscribe for securities (other than Short Term Rights to
                  which


                                       89
<Page>

                  paragraph (2) of this Section 1704 applies), the Conversion
                  Price shall be reduced by multiplying such Conversion Price
                  by a fraction of which the numerator shall be the current
                  market price per share determined as provided in paragraph
                  (7) of this Section 1704) of the Common Stock of the
                  Company on the Reference Date (as defined below) less the
                  fair market value (as determined in good faith by the Board
                  of Directors, whose determination shall be conclusive and
                  described in a Board Resolution filed with the Trustee), on
                  the Reference Date, of the portion of the evidences of
                  indebtedness and other assets so distributed or of such
                  subscription rights or warrants applicable to one share of
                  Common Stock (collectively, the "Market Value of the
                  Distribution") and the denominator shall be such current
                  market price per share of the Common Stock of the Company.
                  Such reduction shall become effective immediately prior to
                  the opening of business on the day (the "Reference Date")
                  following the later of (a) the date fixed for the payment
                  of such distribution and (b) the date 20 days after notice
                  relating to such distribution is required to be given
                  pursuant to Section 1706(a). If the Board of Directors
                  determines the fair market value of any distribution for
                  purposes of this paragraph (4) by reference to the actual
                  or when issued trading market for any securities comprising
                  such distribution, it must in doing so consider the prices
                  in such market over the same period used in computing the
                  current market price per share pursuant to paragraph (7) of
                  this Section 1704. In the event that, with respect to any
                  distribution to which this paragraph (4) of Section 1704
                  would otherwise apply, the Market Value of the Distribution
                  is greater than the current market price per share of the
                  Common Stock (such distribution being referred to herein as
                  an "Unadjusted Distribution"), then the adjustment provided
                  by this paragraph (4) shall not be made and in lieu thereof
                  the provisions of Section 1711 shall apply with respect to
                  such Unadjusted Distribution.

                  (5) The Company may, but shall not be required to, make such
                  reductions in the Conversion Price, in addition to those
                  required by paragraphs (1), (2), (3), and (4) of this Section
                  1704, as it considers to be advisable in order that any event
                  treated for Federal income tax purposes as a dividend of stock
                  or stock rights shall not be taxable to the recipients. In
                  addition, the Company, from time to time, may decrease the
                  Conversion Price by any amount and for any reason, temporarily
                  or otherwise, including situations where the Board of
                  Directors determines such decrease to be fair and appropriate
                  with respect to transactions in which holders of Common Stock
                  have the right to participate.

                  (6) Rights or warrants issued or distributed by the Company to
                  all holders of its Common Stock entitling the holders thereof
                  to subscribe for or purchase shares of Common Stock or
                  Preferred Stock, which rights or warrants (i) are deemed to be
                  transferred with such shares of Common Stock, (ii) are not
                  exercisable and (iii) are also issued or distributed in
                  respect of future issuances of Common Stock, in each case in
                  clauses (i) through (iii) until the occurrence of a specified
                  event or events ("Trigger Events"), shall for purposes of this
                  Section 1704 not be deemed issued or distributed until the
                  occurrence of the earliest Trigger Event. Each share of Common
                  Stock issued upon conversion of Securities pursuant to this
                  Article Seventeen shall be entitled to receive the appropriate
                  number of Common Stock


                                       90

<Page>

                  purchase rights (the "Rights"), if any, and the certificates
                  representing the Common Stock issued upon conversion shall
                  bear such legends, if any[, in each case as provided by and
                  subject to the terms of the [Stockholders Rights Plan] adopted
                  by the Board of Directors on ______________ (the "Rights
                  Plan") as in effect at the time of such conversion].
                  Notwithstanding anything to the contrary in this Article
                  Seventeen, there shall not be any adjustment to the Conversion
                  Price as a result of (i) the distribution of separate
                  certificates representing the Rights; (ii) the occurrence of
                  certain events entitling holders of Rights to receive, upon
                  exercise thereof, Common Stock or other securities of the
                  Company or other securities of another corporation; or (iii)
                  the exercise of such Rights, all in accordance with the Rights
                  Plan. No adjustment in the Conversion Price need be made for
                  rights to purchase or the sale of Common Stock pursuant to a
                  company plan providing for reinvestment of dividends or
                  interest.

                  (7) For the purpose of any computation under paragraph (2),
                  (4) or (5) of this Section 1704, the "current market price"
                  per share of Common Stock of the Company on any date shall be
                  deemed to be the average of the daily Closing Prices for the
                  15 consecutive Trading Days selected by the Company commencing
                  not more than 30 Trading Days before, and ending not later
                  than, the date in question.

                  (8) No adjustment in the Conversion Price shall be required
                  unless such adjustment would require an increase or decrease
                  of at least 1% in the Conversion Price; provided, however,
                  that any adjustments which by reason of this paragraph (8) are
                  not required to be made shall be carried forward and taken
                  into account in any subsequent adjustment. All calculations
                  under this Article Seventeen shall be made to the nearest cent
                  or to the nearest one-hundredth of a share of Common Stock, as
                  the case may be.

                  (9) Anything herein to the contrary notwithstanding, in the
                  event the Company shall declare any dividend or distribution
                  requiring an adjustment in the Conversion Price hereunder and
                  shall, thereafter and before the payment of such dividend or
                  distribution to stockholders, legally abandon its plan to pay
                  such dividend or distribution, the Conversion Price then in
                  effect hereunder, if changed to reflect such dividend or
                  distribution, shall upon the legal abandonment of such plan be
                  changed to the Conversion Price which would have been in
                  effect at the time of such abandonment (after giving effect to
                  all other adjustments not so legally abandoned pursuant to the
                  provisions of this Article Seventeen) had such dividend or
                  distribution never been declared.

                  (10) Notwithstanding any other provision of this Section 1704,
                  no adjustment to the Conversion Price shall reduce the
                  Conversion Price below the then par value per share of the
                  Common Stock of the Company, and any such purported adjustment
                  shall instead reduce the Conversion Price to such par value.
                  Notwithstanding the foregoing sentence, the Company hereby
                  covenants that it will from time to time take all such action
                  as may be required to assure that the par value per share of
                  the Common Stock is at all times equal to or less than the
                  Conversion Price.

                  (11) In the event that this Article Seventeen requires
                  adjustments to the Conversion Price under more than one of
                  paragraphs (1), (2), (3) or (4) of this Section 1704, and the
                  record or effective dates for the transaction giving rise to
                  such adjustments shall occur on the same date, then such
                  adjustments shall be made by applying (to the extent they are
                  applicable), first, the provisions of paragraph (3) of this
                  Section 1704, second, the provisions of paragraph (1) of this
                  Section 1704, third, the provisions of paragraph (4) of this
                  Section 1704 and, fourth, the provisions of paragraph (2) of
                  this Section 1704. Anything herein to the contrary
                  notwithstanding, no single event shall require or result in
                  duplicative adjustments in the Conversion Price pursuant to
                  this Section 1704. After an adjustment to the Conversion Price
                  under this Article Seventeen, any subsequent event requiring
                  an adjustment under this Article Seventeen shall cause an
                  adjustment to the Conversion Price as so adjusted. If, after
                  an adjustment, a Holder of a Security upon conversion of such
                  Security receives shares of two or more classes of Capital
                  Stock of the Company, the Conversion Price shall thereafter be
                  subject to adjustment upon the occurrence of an action taken
                  with respect to any such class of Capital Stock as is
                  contemplated by this Article Seventeen with respect to the
                  Common Stock in this Article Seventeen.

                  SECTION 1705. Notice of Adjustments of Conversion Price.
Whenever the Conversion Price is adjusted as herein provided:

                  (1) the Company shall compute the adjusted Conversion Price in
                  accordance with Section 1704 or Section 1711 and shall prepare
                  an Officer's Certificate setting forth the adjusted Conversion
                  Price and showing in reasonable detail the facts upon which
                  such adjustment is based, and such certificate shall forthwith
                  be filed (with a copy to the Trustee) at each office or agency
                  maintained for the purpose of conversion of any Securities
                  pursuant to Section 1002; and

                  (2) a notice stating that the Conversion Price has been
                  adjusted and setting forth the adjusted Conversion Price shall
                  forthwith be required, and as soon as practicable after it is
                  required, such notice shall be mailed by the Company to all
                  Holders at their last addresses as they shall appear in the
                  Security Register.

         SECTION 1706.  Notice of Certain Corporate Action.  In case:

                  (1) the Company shall take any action that would require a
                  Conversion Price adjustment pursuant to Section 1704 or
                  Section 1711; or

                  (2) there shall occur any reclassification of the Common Stock
                  of the Company (other than a subdivision or combination of its
                  outstanding shares of Common Stock), or any consolidation or
                  merger to which the Company is a party, or the sale, transfer
                  or lease of all or substantially all of the assets of the
                  Company and for which approval of any stockholders of the
                  Company is required; or

                  (3) there shall occur the voluntary or involuntary
                  dissolution, liquidation or winding up of the Company, then
                  the Company shall cause to be filed at each office or agency
                  maintained for the purpose of conversion of Securities
                  pursuant


                                      92
<Page>


                  to Section 1002, and shall cause to be mailed to all Holders
                  at their last addresses as they shall appear in the Security
                  Register, at least 10 days prior to the applicable record,
                  effective or expiration date hereinafter specified, a notice
                  stating (x) the date on which a record is to be taken for the
                  purpose of any dividend, distribution or granting of rights,
                  warrants or options, or, if a record is not to be taken, the
                  date as of which the holders of Common Stock of record to be
                  entitled to such dividend, distribution, rights, options or
                  warrants are to be determined, or (y) the date on which such
                  reclassification, consolidation, merger, sale, transfer,
                  dissolution, liquidation or winding up is expected to become
                  effective, and, if applicable, the date as of which it is
                  expected that holders of Common Stock of record shall be
                  entitled to exchange their shares of Common Stock for
                  securities, cash or other property deliverable upon such
                  reclassification, consolidation, merger, sale, transfer,
                  dissolution, liquidation or winding up.

                  SECTION 1707. Company to Reserve Common Stock. The Company
shall at all times reserve and keep available, free from preemptive rights, out
of its authorized but unissued Common Stock, for the purpose of effecting the
conversion of Securities, a number of shares of Common Stock for the conversion
of all outstanding Securities of any series which is convertible into Common
Stock.

                  SECTION 1708. Taxes on Conversion. The Company will pay any
and all taxes that may be payable in respect of the issue or delivery of shares
of Common Stock on conversion of Securities pursuant hereto. The Company shall
not, however, be required to pay any tax which may be payable in respect of any
transfer involved in the issue and delivery of shares of Common Stock in a name
other than that of the Holder of the Security or Securities to be converted, and
no such issue or delivery shall be made unless and until the Person requesting
such issue has paid to the Company the amount of any such tax, or has
established to the satisfaction of the Company that such tax has been paid.

                  SECTION 1709. Covenants as to Common Stock. The Company
covenants that all shares of Common Stock which may be issued upon conversion of
Securities will upon issue be duly and validly issued, fully paid and
nonassessable, free of preemptive or any similar rights, and, except as provided
in Section 1708, the Company will pay all taxes, liens and charges with respect
to the issue thereof.

                  The Company will endeavor promptly to comply with all Federal
and state securities laws regulating the offer and delivery of shares of Common
Stock upon conversion of Securities, if any, and will list or cause to have
quoted such shares of Common Stock on each national securities exchange or in
the over-the-counter market or such other market on which the Common Stock is
then listed or quoted.

                  SECTION 1710. Cancellation of Converted Securities. All
Securities delivered for conversion shall be delivered to the Trustee to be
cancelled by or at the direction of the Trustee, which shall dispose of the same
as provided in Section 309.

                  SECTION 1711. Provisions in Case of Consolidation, Merger or
Sale of Assets; Special Distributions. If any of the following shall occur,
namely: (i) any reclassification or change of outstanding shares of Common Stock
issuable upon conversion of Securities (other


                                      93
<Page>


than a change in par value, or from par value to no par value, or from no par
value to par value, or as a result of a subdivision or combination), (ii) any
consolidation or merger to which the Company is a party other than a merger in
which the Company is the continuing corporation and which does not result in any
reclassification of, or change (other than a change in name, or par value, or
from par value to no par value, or from no par value to par value or as a result
of a subdivision or combination) in, outstanding shares of Common Stock or (iii)
any sale or conveyance of all or substantially all of the property or business
of the Company as an entirety, then the Person formed by such consolidation or
resulting from such merger or which acquires such properties or assets, as the
case may be, shall as a condition precedent to such transaction execute and
deliver to the Trustee a supplemental indenture providing that the Holder of
each Security then outstanding shall have the right thereafter, during the
period such Security shall be convertible as specified in Section 1701, to
convert such Security only into the kind and amount of securities, cash and
other property receivable, if any, upon such consolidation, merger, sale,
transfer or lease by a holder of the number of shares of Common Stock of the
Company into which such Security might have been converted immediately prior to
such consolidation, merger, sale, transfer or lease; provided that the kind and
amount of securities, cash and other property so receivable shall be determined
on the basis of the following assumptions. The holder of Common Stock referred
to in the foregoing sentence:

                  (1) is not (a) a Person with which the Company consolidated,
                  (b) a Person into which the Company merged or which merged
                  into the Company, or (c) a Person to which such sale, transfer
                  or lease was made (any Person described in the foregoing
                  clauses (a), (b), or (c), hereinafter referred to as a
                  "Constituent Person"), or (d) an Affiliate of a Constituent
                  Person; and

                  (2) failed to exercise his rights of election, if any, as to
                  the kind or amount of securities, cash and other property
                  receivable upon such consolidation, merger, sale, transfer or
                  lease (provided that if the kind or amount of securities, cash
                  and other property receivable upon such consolidation, merger,
                  sale transfer or lease is not the same for each share of
                  Common Stock of the Company in respect of which such rights of
                  election shall not have been exercised, then for the purpose
                  of this Section 1711 the kind and amount of securities, cash
                  and other property receivable upon such consolidation, merger,
                  sale, transfer or lease shall be deemed to be the kind and
                  amount so receivable per share by a plurality of such shares
                  of Common Stock).

                  Such supplemental indenture shall provide for adjustments
which, for events subsequent to the effective date of such supplemental
indenture, shall be as nearly equivalent as may be practicable to the
adjustments provided for in this Article Seventeen. If, in the case of any such
consolidation, merger, sale transfer or lease the stock or other securities and
property (including cash) receivable thereupon by a holder of Common Stock
includes shares of stock or other securities and property of a corporation other
than the successor or purchasing corporation, as the case may be, in such
consolidation, merger, sale, transfer or lease then such supplemental indenture
shall also be executed by such other corporation and shall contain such
additional provisions to protect the interests of the Holders of the Securities
as the Board of Directors of the Company shall reasonably consider necessary by
reason of the foregoing. The above provisions of this Section 1711 shall
similarly apply to successive consolidations, mergers, sales, transfers or
leases.


                                      94
<Page>


                  In the event the Company shall execute a supplemental
indenture pursuant to this Section 1711, the Company shall promptly file with
the Trustee an Officers' Certificate briefly stating the reasons therefor, the
kind or amount of shares of stock or securities or property (including cash)
receivable by Holders of the Securities upon the conversion of their Securities
after any such reclassification, change, consolidation, merger, sale, transfer
or lease and any adjustment to be made with respect thereto.

                  If the Company makes a distribution to all holders of its
Common Stock that constitutes an Unadjusted Distribution pursuant to the last
sentence of paragraph (4) of Section 1704, then, from and after the record date
for determining the holders of Common Stock entitled to receive such
distribution (the "Distribution Record Date"), a Holder of a Security who
converts such Security in accordance with the provisions of this Indenture
shall, upon conversion, be entitled to receive, in addition to the shares of
Common Stock into which the Security is convertible, the kind and amount of
evidences of indebtedness, shares of Capital Stock, or other assets or
subscription rights or warrants, as the case may be, comprising the distribution
that such Holder would have received if such Holder had converted the Security
immediately prior to the Distribution Record Date.

                  SECTION 1712. Trustee Adjustment Disclaimer; Company
Determination Final. The Trustee has no duty to determine when an adjustment
under this Article Seventeen should be made, how it should be made or what it
should be. The Trustee has no duty to determine whether a supplemental indenture
under Section 1711 need be entered into or whether any provisions of any
supplemental indenture are correct. The Trustee shall not be accountable for and
makes no representation as to the validity or value of any securities or assets
issued upon conversion of Securities. The Trustee shall not be responsible for
the Company's failure to comply with this Article Seventeen. Any determination
that the Company or the Board of Directors must make pursuant to this Article
Seventeen is conclusive, absent manifest error.

         SECTION 1713.  When No Adjustment Required.

                  (a) Except as expressly set forth in Section 1704, no
                  adjustment in the Conversion Price shall be made because the
                  Company issues, in exchange for cash, property or services,
                  shares of its Common Stock, or any securities convertible into
                  or exchangeable for shares of its Common Stock, or securities
                  (including warrants, rights and options) carrying the right to
                  subscribe for or purchase shares of its Common Stock or such
                  convertible or exchangeable securities.

                  (b) Notwithstanding anything herein to the contrary, no
                  adjustment in the Conversion Price shall be made pursuant to
                  Section 1704 in respect of any dividend or distribution if the
                  Holders may participate therein (on a basis to be determined
                  in good faith by the Board of Directors) and receive the same
                  consideration they would have received if they had converted
                  the Securities immediately prior to the record date with
                  respect to such dividend or distribution.

                  SECTION 1714. Equivalent Adjustments. In the event that, as a
result of an adjustment made pursuant to Section 1704 above, the holder of any
Security thereafter surrendered for conversion shall become entitled to receive
any shares of Capital Stock of the


                                      95
<Page>


Company other than shares of its Common Stock, thereafter the Conversion Price
of such other shares so receivable upon conversion of any Securities shall be
subject to adjustment from time to time in a manner and on terms as nearly
equivalent as practicable to the provisions with respect to Common Stock
contained in this Article Seventeen.

                  The Indenture permits, with certain exceptions as therein
provided, the amendment thereof and the modification of the rights and
obligations of the Company and the rights of the Holders of the Securities under
the Indenture at any time by the Company and the Trustee with the consent of the
Holders of not less than a majority of the aggregate principal amount of all
Securities issued under the Indenture at the time Outstanding and affected
thereby. The Indenture also contains provisions permitting the Holders of not
less than a majority of the aggregate principal amount of the Outstanding
Securities, on behalf of the Holders of all such Securities, to waive compliance
by the Company with certain provisions of the Indenture. Furthermore, provisions
in the Indenture permit the Holders of not less than a majority of the aggregate
principal amount, in certain instances, of the Outstanding Securities of any
series to waive, on behalf of all of the Holders of Securities of such series,
certain past defaults under the Indenture and their consequences. Any such
consent or waiver by the Holder of this Security shall be conclusive and binding
upon such Holder and upon all future Holders of this Security and other
Securities issued upon the registration of transfer hereof or in exchange
herefor or in lieu hereof, whether or not notation of such consent or waiver is
made upon this Security.

                  No reference herein to the Indenture and no provision of this
Security or of the Indenture shall alter or impair the obligation of the
Company, which is absolute and unconditional, to pay the principal of (and
premium or Make-Whole Amount, if any) and interest on this Security at the
times, places and rate, and in the coin or currency, herein prescribed.

                  As provided in the Indenture and subject to certain
limitations therein [and herein] set forth, the transfer of this Security is
registrable in the Security Register of the Company upon surrender of this
Security for registration of transfer at the office or agency of the Company in
any place where the principal of (and premium or Make-Whole Amount, if any) and
interest on this Security are payable, duly endorsed by, or accompanied by a
written instrument of transfer in form satisfactory to the Company and the
Security Registrar duly executed by, the Holder hereof or by his attorney duly
authorized in writing, and thereupon one or more new Securities, of authorized
denominations and for the same aggregate principal amount, will be issued to the
designated transferee or transferees.

                  As provided in the Indenture and subject to certain
limitations therein [and herein] set forth, this Security is exchangeable for a
like aggregate principal amount of Securities of different authorized
denominations but otherwise having the same terms and conditions, as requested
by the Holder hereof surrendering the same.

                  This Security is subordinated to the prior payment in full in
cash of Senior Debt to the extent set forth in Article Sixteen of the Indenture.

                  The Securities of this series are issuable only in registered
form [without coupons] in denominations of $_______ and any integral multiple
thereof.

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

                  Prior to due presentment of this Security for registration of
transfer, the Company, the Trustee and any agent of the Company or the Trustee
may treat the Person in whose name


                                      104

this Security is registered as the owner hereof for all purposes, whether or not
this Security be overdue, and neither the Company, the Trustee nor any such
agent shall be affected by notice to the contrary.

                  No recourse shall be had for the payment of the principal of
or premium or Make-Whole Amount, if any, or the interest on this Security, or
for any claim based hereon, or otherwise in respect hereof, or based on or in
respect of the Indenture or any indenture supplemental thereto, against any
past, present or future stockholder, employee, officer or director, as such, of
the Company or of any successor, either directly or through the Company or any
successor, whether by virtue of any constitution, statute or rule of law or by
the enforcement of any assessment or penalty or otherwise, all such liability
being, by the acceptance hereof and as part of the consideration for the issue
hereof, expressly waived and released.

                  The Indenture and the Securities shall be governed by and
construed in accordance with the laws of [___________] applicable to agreements
