     authorization, direction, notice, consent, waiver or other
     action provided by this Indenture to be given or taken by

     sufficient for any purpose of this Indenture and (subject
     to Section 315 of the Trust Indenture Act) conclusive in

     Holder of a global Security, may make, give or take, by a

     demand, authorization, direction, notice, consent, waiver
     or other action provided in this Indenture to be made,
     given or taken by Holders, and a U.S. Depository that is a
     Holder of a global Security may provide its proxy or
     proxies to the beneficial owners of interests in any such
     global Security through such U.S. Depositary's standing
     instructions and customary practices.

     date for the purpose of determining the Persons who are
     beneficial owners of interest in any permanent global
     Security held by a U.S. Depositary entitled under the
     procedures of such U.S. Depositary to make, give or take,
     by a proxy or proxies duly appointed in writing, any
     request, demand, authorization, direction, notice,
     consent, waiver or other action provided in this Indenture
     to be made, given or taken by Holders. If such a record
     date is fixed, the Holders on such record date or their
     duly appointed proxy or proxies, and only such Persons,
     shall be entitled to make, give or take such request,
     demand, authorization, direction, notice, consent, waiver
     or other action, whether or not such Holders remain
     Holders after such record date. No such request, demand,
     authorization, direction, notice, consent, waiver or other
     action shall be valid or effective if made, given or taken
     more than 90 days after such record date.

              (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 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 manner which the
     Trustee deems sufficient.

              (c)    The ownership, principal amount and serial
     numbers of Bearer Securities held by any Person, and the
     date of the commencement and the date of termination of
     holding the same, may be proved by the production of such
     Bearer Securities or by a certificate executed, as
     Depositary, by any trust company, bank, banker or other
     depositary reasonably acceptable to the Company, 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
     Depositary, 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, (2) such Bearer Security
     is produced to the Trustee by some other Person, (3) such
     Bearer Security is surrendered in exchange for a
     Registered Security or (4) such Bearer Security is no
     longer Outstanding.

     instrument or writing pursuant to clause (c) above, the
     authority of the Person executing the same and the
     principal amount and serial numbers of Bearer Securities
     held by the Person so executing such instrument or writing
     and the date of the commencement and the date of
     termination of holding the same may also be proved in any
     other manner which the Trustee deems sufficient; and the
     Trustee may in any instance require further proof with
     respect to any of the matters referred to in this clause.

              (e)    The ownership of Registered Securities
     shall be proved by the Security Register.

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

              (g)    Whenever for purposes of any Act to be
     taken hereunder by the Holders of a series of Securities
     denominated in a Foreign Currency (or any currency unit),
     the principal amount of Securities is required to be
     determined, the aggregate principal amount of such
     Securities shall be deemed to be that amount of Dollars
     that could be obtained for such principal amount on the
     basis of the spot rate of exchange for such Foreign
     Currency or such currency unit as determined by the
     Company or by an authorized exchange rate agent and
     evidenced to the Trustee by an Officers' Certificate as of
     the date taking of such Act by the Holders of the
     requisite percentage in principal amount of the Securities
     is evidenced to the Trustee. An exchange rate agent may be
     authorized in advance or from time to time by the Company,
     and may be the Trustee or its Affiliate. Any such
     determination by the Company or by any such exchange rate
     agent shall be conclusive and binding on all Holders, the
     Company and the Trustee, and neither the Company nor any
     such exchange rate agent shall be liable therefor in the
     absence of bad faith.

              (h)    If the Company shall solicit from the
     Holders of any Registered Securities, any request, demand,
     authorization, direction, notice, consent, waiver or other
     Act, the Company may, at its option, by or pursuant to a
     Board Resolution, fix in advance a record date for the
     determination of Holders of Registered Securities entitled
     to give such request, demand, authorization, direction,
     notice, consent, waiver or other Act, but the Company
     shall have no obligation to do so. If such a record date
     is fixed, such request, demand, authorization, direction,
     notice, consent, waiver or other Act may be given before
     or after such record date, but only the Holders of
     Registered Securities 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 six months after the record date.

     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 its Corporate Trust Office, 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 instrument or at
     any other address previously furnished in writing to the
     Trustee by the Company.

     SECTION 106.    Notice to Holders of Securities; Waiver.

              Where this Indenture provides for notice to
     Holders of Securities of any event, (i) if any of the
     Securities affected by such event are Registered
     Securities, such notice to the Holders thereof 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, within
     the time prescribed for the giving of such notice and (ii)
     if any of the Securities affected by such event are Bearer
     Securities, notice to the Holders thereof shall be
     sufficiently given (unless otherwise herein or in the
     terms of such Bearer Securities expressly provided) if
     published once in an Authorized Newspaper in New York, New
     York, and in such other city or cities, if any, as may be
     specified in such Securities and, if the Securities of
     such series are listed on any stock exchange outside the
     United States, in any place at which such Securities are
     listed on a securities exchange to the extent that such
     securities exchange so requires, and mailed to such
     Persons whose names and addresses as were previously filed
     with the Trustee, within the time prescribed for giving
     such notice. In any case where notice to Holders 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. In case 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 publication in
     lieu thereof as shall be made with the approval of the
     Trustee shall constitute a sufficient publication of such
     notice. Neither failure to give notice by publication to
     Holders of Bearer Securities as provided above, nor any
     defect in any notice so published, shall affect the
     sufficiency of any notice mailed to Holders of Registered
     Securities as provided above.

              Any notice which is mailed in the manner herein
     provided shall be conclusively presumed to have been duly
     given or provided. In case by reason of the suspension of
     regular mail service or by reason of any other cause it
     shall be impracticable to give such notice as provided
     above, then such notification as shall be made with the
     approval of the Trustee shall constitute a sufficient
     notification for every purpose hereunder.
<PAGE 16>

              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.    Conflict with Trust Indenture Act.

              This Indenture is subject to the Trust Indenture
     Act and if any provision hereof limits, qualifies or
     conflicts with a provision of the Trust Indenture Act that
     is required under such Trust Indenture Act to be a part of
     and govern this Indenture, the latter 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.

     SECTION 108.    Effect of Headings and Table of Contents.

              The Article and Section headings herein and the
     Table of Contents are for convenience only and shall not
     affect the construction hereof.

     SECTION 109.    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 110.    Separability Clause.

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

     SECTION 111.    Benefits of Indenture.

              Nothing in this Indenture, any Security or any
     Coupon, express or implied, shall give to any Person,
     other than the parties hereto, any Security Registrar, any
     paying agent and their successors hereunder and the
     Holders, any benefit or any legal or equitable right,
     remedy or claim under this Indenture.

     SECTION 112.    Governing Law.

              This Indenture, the Securities and any Coupons
     shall be governed by and construed in accordance with the
     laws of the State of New York applicable to agreements
     made or instruments entered into and, in each case,
     performed in such state.
<PAGE 17>

     SECTION 113.    Moneys of Different Currencies to be
                     Segregated.

              The Trustee shall segregate monies, funds, and
     accounts held by the Trustee hereunder in one currency (or
     unit thereof) from any monies, funds or accounts in any
     other currencies (or units thereof), notwithstanding any
     provision herein which would otherwise permit the Trustee
     to commingle such amounts.

     SECTION 114.    Payment to be in Proper Currency.

              The following provisions of this Section 114
     shall apply to the extent permitted by applicable law:  In
     the case of any Security payable in any particular
     currency or currency unit (the "Required Currency"),
     except as otherwise provided herein, therein or in or
     pursuant to the related Board Resolution or supplemental
     indenture or as contemplated by Section 301, the
     obligation of the Company to make any payment of
     principal, premium or interest thereon shall not be
     discharged or satisfied by any tender by the Company, or
     recovery by the Trustee, in any currency or currency unit
     other than the Required Currency, except to the extent
     that such tender or recovery shall result in the Trustee
     timely holding the full amount of the Required Currency
     then due and payable. If any such tender or recovery is
     made in other than the Required Currency, the Trustee may,
     but shall not be obligated to, take such actions as it
     considers appropriate to exchange such other currency or
     currency unit for the Required Currency. The costs and
     risks of any such exchange, including without limitation
     the risks of delay and exchange rate fluctuation, shall be
     borne by the Company, the Company shall remain fully
     liable for any shortfall or delinquency in the full amount
     of the Required Currency then due and payable and in no
     circumstances shall the Trustee be liable therefor. The
     Company hereby waives any defense of payment based upon
     any such tender or recovery which is not in the Required
     Currency, or which, when exchanged for the Required
     Currency by the Trustee, is less than the full amount of
     Required Currency then due and payable.

     SECTION 115.    Language of Notices.

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

     SECTION 116.    Legal Holidays.

              In any case where any Interest Payment Date,
     Stated Maturity or Maturity of any Security shall be a
     Legal Holiday at any Place of Payment, then
     (notwithstanding any other provision of this Indenture,
     any Security or any Coupon other than a provision in this
     Indenture, any Security or Coupon that specifically states
     that such provision shall apply in lieu of this Section)
     payment need not be made at such Place of Payment on such
     date, but may be made on the next succeeding day that is a
     Business Day at such Place of Payment with the same force
     and effect as if made on the Interest Payment Date or at
     the Stated Maturity or Maturity, and no interest shall
     accrue on the amount payable on such date or at such time
     for the period from and after such Interest Payment Date
     or Stated Maturity or Maturity, as the case may be.

                              SECURITY FORMS

     SECTION 201.    Forms Generally.

              The Securities of each series and the Coupons, if
     any, to be attached thereto shall be in substantially such
     form as shall be established by or pursuant to a Board
     Resolution or in one or more indentures supplemental
     hereto, in each case with such appropriate insertions,
     omissions, substitutions and other variations as are
     required or permitted by this Indenture or indenture
     supplemental hereto, and may have such letters, numbers or
     other marks of identification and such legends or
     endorsements placed thereon as may be required to comply
     with the rules of any securities exchange or as may,
     consistently herewith, be determined by the officers
     executing such Securities and Coupons, if any, as
     evidenced by their execution of the Securities and
     Coupons, if any. If temporary Securities of any series are
     issued in global form as permitted by Section 304, the
     form thereof also shall be established as provided in the
     preceding sentence. If the forms of Securities and
     Coupons, if any, of any series are established by, or by
     action taken pursuant to, a Board Resolution, a copy of
     the Board Resolution together with an appropriate record
     of any such action taken pursuant thereto, including a
     copy of the approved form of Securities or Coupons, if
     any, shall be certified by the Secretary or an Assistant
     Secretary of the Company and delivered to the Trustee at
     or prior to the delivery of the Company Order contemplated
     by Section 303 for the authentication and delivery of such
     Securities.

              The Trustee's certificates of authentication
     shall be in substantially the form set forth in Section 202.

              Unless otherwise provided in or pursuant to this
     Indenture, the Securities shall be issuable in registered
     form without Coupons and shall not be issuable upon the
     exercise of warrants.

              The definitive Securities and Coupons, if any,
     shall be printed, lithographed or engraved on steel
     engraved borders or may be produced in any other manner,
     all as determined by the officers executing such
     Securities and Coupons, if any, as evidenced by their
     execution of such Securities and Coupons, if any.

     SECTION 202.    Form of Trustee's Certificate of
                     Authentication.

              Subject to Section 610, the Trustee's certificate
     of authentication shall be in substantially the following
     form:
     <PAGE 19>

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

                                 BANK ONE, NA
                                 as Trustee

                                     Authorized Signatory

     SECTION 203.    Securities in Global Form.

              If Securities of a series are issuable in whole
     or in part in global form, any such Security may provide
     that it shall represent the aggregate or specified amount
     of Outstanding Securities from time to time endorsed
     thereon and may also provide that the aggregate amount of
     Outstanding Securities represented thereby may from time
     to time be reduced to reflect exchanges. Any endorsement
     of a Security in global form to reflect the amount, or any
     increase or decrease in the amount or changes in the
     rights of Holders of Outstanding Securities represented
     thereby, shall be made in such manner and by such Person
     or Persons as shall be specified therein or in the Company
     Order to be delivered pursuant to Section 303 or 304 with
     respect thereto. Subject to the provisions of Section 303
     and, if applicable, Section 304, the Trustee shall deliver
     and redeliver any Security in permanent global form in the
     manner and upon instructions given by the Person or
     Persons specified therein or in the applicable 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 a Security in
     global form shall be in writing but need not be
     accompanied by or contained in an Officers' Certificate
     and need not be accompanied by an Opinion of Counsel. Any
     instructions by the Company with respect to a Security in
     global form shall be in writing but need not comply with
     Section 314(e) of the Trust Indenture Act.

     Book-Entry Securities, and the Depositary for such global
     Securities and, if so, (i) whether beneficial owners of
     interests in any such global Security may exchange such
     interest for Securities of the same series and of like
     tenor and of any authorized form and denomination, and the
     circumstances under which any such exchanges may occur, if
     other than in the manner specified in Section 305, and
     (ii) the name of the Depositary or the U.S. Depositary, as
     the case may be, with respect to any global Security;

              (21)  the application, if any, of Section 403;

              (22)  the application, if any, of Section 1007;

              (23)  if any of such Securities are to be
     issuable upon the exercise of warrants, this shall be so
     established and (if established by Board Resolution) so
     set forth, as well as the time, manner and place for such
     Securities to be authenticated and delivered;

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

              (25)  if there is more than one Trustee, the
     identity of the Trustee and, if not the Trustee, the
     identity of each Security Registrar, Paying Agent or
     Authenticating Agent with respect to such Securities; and

              (26)  any other terms of the series of Securities
     (which terms shall not be inconsistent with the provisions
     of this Indenture).

              All Securities (including Coupons, if any) of any
     one series shall be substantially identical except as to
     Currency of payments due thereunder, denomination and the
     rate or rates of interest, if any, the method or methods,
     if any, by which such rate or rates are to be determined
     and Maturity, the date from which interest, if any, shall
     accrue and except as may otherwise be provided in or
     pursuant to such Board Resolution 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 so
     provided by the Company, a series may be reopened for
     issuances of additional Securities of such series or to
     establish additional terms of such series of Securities.

              If any of the terms of the series of Securities
     are established by action taken pursuant to a Board
     Resolution, a copy of an appropriate record of such action
     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 series.

     SECTION 302.    Currency; Denominations.

              Unless otherwise provided in or pursuant to this
     Indenture, the principal of, any premium and interest on
     and any Additional Amounts with respect to the Securities
     shall be payable in Dollars. The Securities of each series
     shall be issuable in such denominations as shall be
     specified as contemplated by Section 301.  In the absence
     of any such provisions with respect to the Securities of
     any series, the Securities of such series shall be
     issuable in denominations of $1,000, if Registered
     Securities, in denominations of $5,000, if Bearer
     Securities, and, in the case of Registered Securities, any
     integral multiple of the applicable denomination.

     SECTION 303.    Execution, Authentication, Delivery and
                     Dating.

              The Securities shall be executed on behalf of the
     Company by its Chairman of the Board, its Vice Chairman of
     the Board, its President or one of its Vice Presidents,
     under its corporate seal reproduced thereon attested by
     the signature of its Secretary or one of its Assistant
     Secretaries or its Treasurer or one of its Assistant
     Treasurers. The Coupons, if any, shall be executed on
     behalf of the Company by its Chairman of the Board, its
     Vice Chairman of the Board, its President or one of its
     Vice Presidents attested by its Secretary or any Assistant
     Secretary or its Treasurer or one of its Assistant
     Treasurers. The signature of any of these officers on the
     Securities (and Coupons, if any) may be manual or facsimile.

              Securities (and Coupons, if any) 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 (and
     Coupons, if any) or did not hold such offices at the date
     of such Securities (and Coupons, if any).

              At any time and from time to time after the
     execution and delivery of this Indenture, the Company may
     deliver Securities (with or without Coupons) of any series
     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. 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 Sections
     315(a) through 315(d) of the Trust Indenture Act, shall be
     fully protected in relying upon,

              (i)    an Opinion of Counsel stating to the
     effect that:

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

                     (b)  the terms of such Securities and
     Coupons, if any, have been established in conformity with
     the provisions of this Indenture;

                     (c)  the terms of the Securities and
     Coupons, if any, have been established in accordance with
     the terms of this Indenture and all conditions precedent
     provided for in the Indenture relating to the Trustee's
<PAGE 24>

     authentication and delivery of the Securities and Coupons,
     if any, will have been complied with; and

                     (d)  as to such other matters as the
     Trustee may reasonably request; and

              (ii)   an Officers' Certificate stating that, all
     conditions precedent to the authentication and delivery of
     such Securities and Coupons, if any, appertaining thereto,
     have been complied with and to the best knowledge of the
     Persons executing such certificate, no event which is, or
     after notice or lapse of time would become, an Event of
     Default with respect to any of the Securities shall have
     occurred and be continuing.

              The Trustee shall have the right to decline to
     authenticate and deliver such Securities if the Trustee,
     being advised by counsel, determines that such action may
     not lawfully be taken or if the Trustee in good faith by
     its board of directors or trustees, executive committee,
     or a trust committee of directors or trustees and/or
     Responsible Officers shall determine that such action
     would expose the Trustee to personal liability to existing
     Holders or would adversely affect the Trustee's own
     rights, duties or immunities under this Indenture or
     otherwise.

              The Trustee shall not be required to authenticate
     Securities denominated in a coin or currency (or unit
     including a coin or currency) other than that of the
     United States of America if the Trustee reasonably
     determines that such Securities impose duties or
     obligations on the Trustee which the Trustee is not able
     or reasonably willing to accept; provided that the
     Trustee, upon a Company Request, will resign as Trustee
     with respect to Securities of any series as to which such
     a determination is made, prior to the issuance of such
     Securities, and will comply with the request of the
     Company to execute and deliver a supplemental indenture
     appointing a successor Trustee pursuant to Section 901.

              If all the Securities of any series are not to be
     issued at one time, it shall not be necessary to deliver
     an Opinion of Counsel and an Officers' Certificate at the
     time of issuance of each Security, but such opinion and
     certificate, with appropriate modifications, shall be
     delivered at or before the time of issuance of the first
     Security of such series.

              If the Company shall establish pursuant to
     Section 301 that the Securities of a series are to be
     issued in whole or in part in global form, then the
     Company shall execute and the Trustee shall, in accordance
     with this Section and the Company Order with respect to
     such series, authenticate and deliver one or more
     Securities in global form that (i) shall represent and
     shall be denominated in an amount equal to the aggregate
     principal amount of the Outstanding Securities of such
     series to be represented by such global Security or
     Securities, (ii) shall be registered, if in registered
     form, in the name of the Depositary for such Book-Entry
     Security or Securities or the nominee of such Depositary,
     (iii) shall be delivered by the Trustee to such Depositary
     or pursuant to such Depositary's instruction and (iv)
     where such Depositary is The Depository Trust Company,
     shall bear a legend substantially to the following effect:
      "Unless and until it is exchanged in whole or in part for
     Securities in certificated form, this Security may not be
     transferred except as a whole by the Depositary to a
     nominee of the Depositary or by a nominee of the
     Depositary to the Depositary or another nominee of the
     Depositary or by the Depositary or any such nominee to a
     successor Depositary or a nominee of such successor
     Depositary" or to such other effect as the Depositary and
     the Trustee may agree.
<PAGE 25>

              Each Depositary designated pursuant to Section
     301 for a Book-Entry Security in registered form must, at
     the time of its designation and at all times while it
     serves as Depositary, be a clearing agency registered
     under the Exchange Act and any other applicable statute or
     regulation. The Trustee shall have no responsibility to
     determine if the Depositary is so registered. Each
     Depositary shall enter into an agreement with the Trustee
     governing their respective duties and rights with regard
     to Book-Entry Securities.

              Each Security shall be dated the date of its
     authentication, except that each Bearer Security,
     including any Bearer Security in global form, shall be
     dated as of the date specified or contemplated by Section
     301.

              No Security or Coupon appertaining thereto shall
     be entitled to any benefit under this Indenture or be
     valid or obligatory for any purpose unless there appears
     on such Security a certificate of authentication
     substantially in the form provided for herein duly
     executed by the Trustee by manual signature of one of its
     authorized signatories, 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. Except as permitted by Section 306 or 307,
     the Trustee shall not authenticate and deliver any Bearer
     Security unless all appurtenant Coupons then matured have
     been detached and cancelled.

     SECTION 304.    Temporary Securities.

              Pending the preparation of definitive Securities
     of any series, the Company may execute, and upon receipt
     of a 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 and form, with or without Coupons of the
     definitive Securities in lieu of which they are issued and
     with such appropriate insertions, omissions, substitutions
     and other variations as the officers executing such
     Securities may determine, as conclusively evidenced by
     their execution of such Securities and Coupons, if any.
     Such temporary Securities may be in global form.

              Except in the case of temporary Securities in
     global form, each of which shall be exchanged in
     accordance with the provisions thereof, if temporary
     Securities of any series are issued, the Company will
     cause definitive Securities of such series to be prepared
     without unreasonable delay. After the preparation of
     definitive Securities of the same series and containing
     terms and provisions that are identical to those of any
     temporary Securities, 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
     pursuant to Section 1002 in a Place of Payment for such
     series, without charge to the Holder. Upon surrender for
     cancellation of any one or more temporary Securities of
     any series (accompanied by any unmatured 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 and of like
     tenor; provided, however, that no definitive Bearer
     Security shall be delivered in exchange for a temporary
     Registered Security; and provided, further, that no
     definitive Bearer Security shall be delivered in exchange
     for a temporary Bearer Security unless the Trustee shall
     have received from the person entitled to receive the
     definitive Bearer Security a certificate substantially in
     the form approved in the Board Resolutions relating
<PAGE 26>

     thereto and such delivery shall occur only outside the
     United States. 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 except as otherwise specified as
     contemplated by Section 301 with respect to the payment of
     interest on Bearer Securities in temporary form.

     SECTION 305.    Registration, Registration of Transfer and
                     Exchange.

              The Company shall cause to be kept at the
     Corporate Trust Office of the Trustee a register (the
     register maintained in such office and in any other office
     or agency of the Company maintained pursuant to Section
     1002 in a Place of Payment being herein sometimes
     collectively referred to 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 Trustee is hereby appointed "Security
     Registrar" for the purpose of registering Registered
     Securities and transfers of Registered Securities as
     herein provided. In the event that the Trustee shall not
     be the Security Registrar, it shall have the right to
     examine the Security Register at all reasonable times.  In
     the event that the Trustee shall cease to be Security
     Registrar with respect to a series of Securities, it shall
     have the right to examine the Security Register for such
     series at all reasonable times.

              Upon surrender for registration of transfer of
     any Registered Security of any series at the office or
     agency maintained pursuant to Section 1002 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.

              At the option of the Holder, Registered
     Securities of any series (except a Book-Entry Security
     representing all or a portion of the Securities of such
     series) may be exchanged for other Registered Securities
     of the same series, of any authorized denominations and of
     a like aggregate principal amount, upon surrender of the
     Registered Securities to be exchanged at such office or
     agency. Registered Securities may not be exchanged for
     Bearer Securities. Whenever any 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.

              At the option of the Holder, Bearer Securities of
     any series may be exchanged for Registered Securities (if
     the Securities of such series are issuable in registered
     form) or Bearer Securities (if Bearer Securities of such
     series are issuable in more than one denomination and such
     exchanges are permitted by such series) of the same
     series, of any authorized denominations and of like tenor
     and aggregate principal amount, upon surrender of the
     Bearer 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,
     such exchange may be effected if the Bearer Securities are
     accompanied by payment in funds acceptable to the Company
     and the Trustee 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 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
<PAGE 27>

     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 exchange for a Registered Security of the same series
     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 date for payment of Defaulted Interest, such
     Bearer Security shall be surrendered without the Coupon
     relating to such Interest Payment Date or proposed date of
     payment, as the case may be (or, if such Coupon is so
     surrendered with such Bearer Security, such Coupon shall
     be returned to the person so surrendering the Bearer
     Security), and interest or Defaulted Interest, as the case
     may be, shall 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 shall be payable only to the
     Holder of such Coupon when due in accordance with the
     provisions of this Indenture.

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

              If at any time the Depositary for the Securities
     of a series notifies the Company that it is unwilling or
     unable to continue as Depositary for the Securities of
     such series or if at any time the Depositary for the
     Securities of such series shall no longer be eligible
     under Section 303, the Company shall appoint a successor
     Depositary with respect to the Securities of such series.
     If a successor Depositary for the Securities of such
     series is not appointed by the Company within 90 days
     after the issuer receives such notice or becomes aware of
     such ineligibility, the Company's election pursuant to
     Section 301(20) shall no longer be effective with respect
     to the Securities of such series and the Company shall
     execute, and the Trustee, upon receipt of a Company Order
     for the authentication and delivery of certificated
     Securities of such series of like tenor, shall
     authenticate and deliver Securities of such series in
     certificated form in an aggregate principal amount equal
     to the principal amount of the Security or Securities in
     global form representing such series in exchange for such
     Security or Securities in global form.

              The Company may at any time and in its sole
     discretion determine that the Securities of any series
     issued in the form of one or more global Securities shall
     no longer be represented by such global Security or
     Securities. In such event the Company shall execute, and
     the Trustee, upon receipt of a Company Order for the
     authentication and delivery of certificated Securities of
     such series of like tenor, shall authenticate and deliver,
     Securities of such series in certificated form and in an
     aggregate principal amount equal to the principal amount
     of the Security or Securities in global form representing
     such series in exchange for such Security or Securities in
     global form.
<PAGE 28>

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

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

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

              In any exchange provided for in any of the
     preceding three paragraphs, the Company shall execute and
     the Trustee shall authenticate and deliver Securities in
     certificated form in authorized denominations.

              Upon the exchange of a global Security for
     Securities in certificated form, such global Security
     shall be cancelled by the Trustee. Unless expressly
     provided with respect to the Securities of any series that
     such Security may be exchanged for Bearer Securities,
     Securities issued in exchange for a Book-Entry Security
     pursuant to this Section shall be registered in such names
     and in such authorized denominations as the Depositary for
     such Book-Entry Security, pursuant to instructions from
     its direct or indirect participants or otherwise, shall
     instruct the Trustee. The Trustee shall deliver such
     Securities to the Persons in whose names such Securities
     are so registered.

              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.

              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
     entitling the Holders thereof 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 or redemption 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
<PAGE 29>

     transfer or exchange of Securities, other than exchanges
     pursuant to Section 304, 906 or 1107 not involving any
     transfer.

              Except as otherwise provided in or pursuant to
     this Indenture, the Company shall not be required (i) to
     issue, register the transfer of or exchange Securities of
     any series for a period of 15 days before the selection of
     any Securities of that series for redemption, or (ii) to
     register the transfer of or exchange any Registered
     Security so selected for redemption in whole or in part,
     except the unredeemed portion of any Security being
     redeemed in part, 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 with written instruction for payment consistent
     with the provisions of this Indenture or (iv) to issue,
     register the transfer of or exchange any Security which,
     in accordance with its terms, 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 Security with a
     mutilated Coupon appertaining to it is surrendered to the
     Trustee, the Company shall execute and the Trustee shall
     authenticate and deliver in exchange therefor a new
     Security with Coupons corresponding to the Coupons, if
     any, appertaining to the surrendered Security of the same
     series and of like tenor and principal amount 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
     the Trustee (i) evidence to their satisfaction of the
     destruction, loss or theft of any Security or Security
     with a destroyed, lost or stolen 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 a new
     Security of the same series and of like tenor and
     principal amount and bearing a number not
     contemporaneously outstanding with Coupons corresponding
     to the Coupons, if any, appertaining to the destroyed,
     lost or stolen Security.

              Notwithstanding the foregoing provisions of this
     Section 306, 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 or Coupon, pay such
     Security or Coupon; provided, however, that payment of
     principal of and any premium or interest on or any
     Additional Amounts with respect to any Bearer Securities
     shall, except as otherwise provided in Section l002, 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 and any Additional Amounts with respect to such
     interest shall be payable only upon presentation and
     surrender of the Coupons appertaining thereto.
<PAGE 30>

              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.

              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, as amended or
     supplemented pursuant to this Indenture with respect to
     particular Securities or generally, 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 and Certain Additional
                     Amounts; Rights to Interest and Certain
                     Additional Amounts Preserved.

              Unless otherwise provided as contemplated by
     Section 301, interest on and any Additional Amounts with
     respect to any Registered Security which 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. Unless otherwise provided in or
     pursuant to this Indenture, in case a Bearer Security is
     surrendered in exchange for a Registered Security after
     the close of business (at an Office or Agency for such
     Security) on any Regular Record Date therefor and before
     the opening of business (at such Office or Agency) on the
     next succeeding Interest Payment Date therefore, such
     Bearer Security shall be surrendered without the Coupon
     relating to such Interest Payment Date and interest shall
     not be payable on such Interest Payment Date in respect of
     the Registered Security issued in exchange for such Bearer
     Security, but shall be payable only to the Holder of such
     Coupon when due in accordance with the provisions of this
     Indenture.

              Any interest on and any Additional Amounts with
     respect to any Registered Security of any series which is
     payable, but is not punctually paid or duly provided for,
     on any Interest Payment Date (herein called "Defaulted
     Interest") shall forthwith cease to be payable to the
     Holder on the relevant Regular Record Date by virtue of
     having been such Holder, and such Defaulted Interest 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
<PAGE 31>

     the proposed payment, and at the same time the Company
     shall deposit with the Trustee an amount of Money equal to
     the aggregate amount proposed to be paid in respect of
     such Defaulted Interest or shall make arrangements
     satisfactory to the Trustee for such deposit prior to the
     date of the proposed payment, such Money when deposited to
     be held in trust for the benefit of the Persons entitled
     to such Defaulted Interest as is provided in this Clause
     (1). 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 of general circulation in the Borough
     of Manhattan, The City of New York, but such publication
     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 so mailed, such Defaulted Interest
     shall be paid to the Persons in whose names the 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 is surrendered at the Office or Agency for such
     Security in exchange for a Registered Security 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 shall not be
     payable on such proposed date of payment in respect of the
     Registered Security issued in exchange for such Bearer
     Security, but shall be payable only to the Holder of such
     Coupon when due in accordance with the provisions of this
     Indenture.

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

              At the option of the Company, interest on
     Registered Securities of any series that bear interest may
     be paid (i) by mailing a check to the address of the
     Person entitled thereto as such address shall appear in
     the Security Register or (ii) by wire transfer to an
     account maintained by the person entitled thereto as
     specified in the applicable Security Register.

              Notwithstanding the above, except as otherwise
     specified with respect to a series of Securities in
     accordance with the provisions of Section 301, a Holder of
     $10,000,000 or more in aggregate principal amount of
     Securities of the same series having the same Interest
     Payment Date shall, upon written request received by the
     Trustee prior to the Regular Record Date in respect of an
     interest payment, or the date which is 15 days before the
     Stated Maturity or date of redemption of the principal of
     (and premium, if any, on) the Securities, as the case may
     be, be entitled to receive payments of principal of (and
     premium, if any) and interest by wire transfer to an
     account maintained by such Holder with a bank located in
<PAGE 32>

     the United States; provided, however, that no payment of
     principal (and premium, if any) will be made without prior
     presentment and surrender of the Securities.

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

     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 Registered Security for
     the purpose of receiving payment of principal of (and
     premium, if any) and (subject to Section 307) interest on,
     and any Additional Amounts with respect to, 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.

              No Holder of any beneficial interest in any
     global Security held on its behalf by the Depositary shall
     have any rights under this Indenture with respect to such
     global Security, and such Depositary may 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 interest of a global Security or for
     maintaining, supervising or reviewing any records relating
     to such beneficial ownership interest.

              The Company, the Trustee and any agent of the
     Company or the Trustee may treat the bearer of any Bearer
     Security and the bearer of any Coupon as the absolute
     owner of such Bearer Security or Coupon for the purpose of
     receiving payment thereof or on account thereof and for
     all other purposes whatsoever, whether or not such Bearer
     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 the Depositary shall
     have any rights under this Indenture with respect to such
     global Security, and such Depositary may 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 interest of a global Security or for
     maintaining, supervising or reviewing any records relating
     to such beneficial ownership interest.

     SECTION 309.    Cancellation.

              All Securities and Coupons surrendered for
     payment, redemption, 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 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 all Securities and
     Coupons so delivered shall be promptly cancelled by the
     Trustee. No Securities or Coupons shall be authenticated
     in lieu of or in exchange for any Securities or Coupons
     cancelled as provided in this Section, except as expressly
     permitted by this Indenture. All cancelled Securities and
     Coupons held by the Trustee shall be destroyed by the
     Trustee, unless by a Company Order the Company directs
     their return to it, and a certificate evidencing such
     destruction shall be delivered to the Company.

     SECTION 310.    Computation of Interest.

              Except as otherwise specified as contemplated by
     Section 301 for Securities of any series, interest on the
     Securities of each series shall be computed on the basis
     of a 360-day year of twelve 30-day months.

                  SATISFACTION, DISCHARGE AND DEFEASANCE

     SECTION 401.    Satisfaction and Discharge of Indenture.

              This Indenture shall upon Company Request cease
     to be of further effect with respect to Securities of any
     series (except as to any surviving rights of registration
     of transfer or exchange of Securities of such series and
     replacement of lost, stolen or mutilated Securities of
     such series herein expressly provided for) and any Coupons
     appertaining thereto, and the Trustee, at the expense of
     the Company, shall execute proper instruments
     acknowledging satisfaction and discharge of this Indenture
     with respect to such series, when

             (1)     either

                          (A)    all Securities of such series
                     theretofore authenticated and delivered
                     and all Coupons appertaining thereto
                     (other than (i) Coupons appertaining to
                     Bearer Securities of such series
                     surrendered in exchange for Registered
                     Securities and maturing after such
                     exchange, surrender of which is not
                     required or has been waived as provided in
                     Section 305, (ii) Securities of such
                     series and Coupons which have been
                     destroyed, lost or stolen and which have
                     been replaced or paid as provided in
                     Section 306, (iii) Coupons appertaining to
                     Bearer Securities of such series called
                     for redemption and maturing after the
                     relevant Redemption Date, surrender of
                     which has been waived as provided in

                     series and Coupons for whose payment Money
                     has theretofore been deposited in trust or

                     provided in Section 1003) have been
                     delivered to the Trustee for cancellation; or

                          (B)     all such Securities and
                     Coupons of such series not theretofore
                     delivered to the Trustee for cancellation

                          (i)    have become due and payable, or

                          (ii)   will become due and payable at
             their Stated Maturity within one year, or

                          (iii)  if redeemable at the option of
             the Company, are to be called for redemption
             within one year under arrangements satisfactory to
             the Trustee for the giving of notice of redemption
             by the Trustee in the name, and at the expense, of
             the Company,

     and the Company, in the case of (B)(i), (ii) or (iii)
     above, has deposited or caused to be deposited with the
     Trustee as trust funds in trust for the purpose an amount
     sufficient to pay and discharge the entire indebtedness on
     such Securities and Coupons of such series not theretofore
     delivered to the Trustee for cancellation, for principal
     of (and premium, if any) and interest on, and any
     Additional Amounts with respect to such Securities and
     Coupons to the date of such deposit (in the case of
     Securities and Coupons of such series 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 have been complied with.

              In the event there are Securities of two or more
     series hereunder, the Trustee shall be required to execute
     an instrument acknowledging satisfaction and discharge of
     this Indenture only if requested to do so with respect to
     Securities of such series as to which it is Trustee and if
     the other conditions thereto are met.

              Notwithstanding the satisfaction and discharge of
     this Indenture, the obligations of the Company to the
     Trustee under Section 605 and, if Money shall have been
     deposited with 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 Money.

              Subject to the provisions of the last paragraph
     of Section 1003, all Money and Government Obligations
     deposited with the Trustee pursuant to Sections 401 and
     403 shall be held in trust and applied by it, in
     accordance with the provisions of the Securities and
     Coupons, if any, and this Indenture, to the payment,
<PAGE 35>

     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, if any), interest and Additional
     Amounts for whose payment such Money and Government
     Obligations have been deposited with or received by the
     Trustee; but such Money and Government Obligations need
     not be segregated from other funds except to the extent
     required by law.

     SECTION 403.    Satisfaction, Discharge and Defeasance of
                     Securities of Any Series.

              If this Section is specified, as contemplated by
     Section 301, to be applicable to Securities and Coupons,
     if any, of any series, at the Company's option, either

                     (a)  the Company will be deemed to have
     been Discharged (as defined below) from its obligations
     with respect to Securities and Coupons, if any, of such
     series or

                     (b)  the Company will cease to be under
     any obligation to comply with any term, provision or
     condition set forth in (i) Article Eight and Section 1006
     or (ii) the terms, provisions or conditions of such series
     specified pursuant to Section 301 (provided, however, that
     the Company may not cease to comply with any obligations
     as to which it may not be Discharged pursuant to the
     definition of "Discharged"), if, in the case of (a) and
     (b), with respect to the Securities and Coupons, if any,
     of such series on the 91st day after the applicable
     conditions set forth below in (x) and either (y) or (z)
     have been satisfied:

                          (x) (1) the Company has paid or
                     caused to be paid all other sums payable
                     with respect to the Outstanding Securities
                     and Coupons, if any, of such series (in
                     addition to any required under (y) or
                     (z)); and

                                (2)      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 the entire
                     indebtedness on all Outstanding Securities
                     and Coupons, if any, of any such series
                     have been complied with;

                     under any material indenture, agreement or
                     other instrument binding upon the Company
                     or any Subsidiary or any of their
                     properties; and

                                (3) the Company shall have
                     delivered to the Trustee

                          (A)   an Opinion of Counsel to the
                     effect that Holders of the Securities and
                     Coupons, if any, of such series will not
                     recognize income, gain or loss for Federal
                     income tax purposes as a result of the
                     Company's exercise of its option under
                     this Section 403 and will be subject to
                     Federal income tax in the same amount, in
                     the same manner and at the same times as
                     would have been the case if such option
                     had not been exercised; and

                          (B)   if the Securities of such
                     series are then listed on any exchange, an
                     Opinion of Counsel that the Securities of
                     such series shall not be delisted as a
                     result of the exercise of this option;

                          (z)    the Company has properly
                     fulfilled such other means of satisfaction
                     and discharge as is specified, as
                     contemplated by Section 301, to be
                     applicable to the Securities and Coupons,
                     if any, of such series.

              Any deposits with the Trustee referred to in
     clause (y)(1) above shall be irrevocable and shall be made
     under the terms of an escrow trust agreement in form and
     substance satisfactory to the Trustee. If any Outstanding
     Securities and Coupons, if any, of such series are to be
     redeemed prior to their Stated Maturity, whether pursuant
     to any mandatory redemption provisions or in accordance
     with any mandatory sinking fund requirement, the
     applicable escrow trust agreement will provide therefor
     and the Company will make such arrangements as are
     satisfactory to the Trustee for the giving of notice of
     redemption by the Trustee in the name, and at the expense,
     of the Company.

              "Discharged" means that the Company will be
     deemed to have paid and discharged the entire indebtedness
     represented by, and obligations under, the Securities and
     Coupons, if any, of the series as to which this Section is
     specified as applicable as aforesaid and to have satisfied
     all the obligations under this Indenture relating to the
     Securities and Coupons, if any, of such series (and the
     Trustee, at the expense of the Company, will execute
     proper instruments acknowledging the same), except (A) the
     rights of Holders thereof to receive, from the trust fund
     described in clause (y)(1) above, payments of the
<PAGE 37>

     principal of, premium and the interest, if any, on such
     Securities and Coupons, if any, when such payments are
     due, (B) the Company's obligations with respect to such
     Securities and Coupons, if any, under Sections 305 and 306
     (insofar as applicable to Securities of such series), 402,
     1002 and 1003 (last paragraph only) and the Company's
     obligations to the Trustee under Sections 605 and 606 and
     (C) the rights, powers, trusts, duties and immunities of
     the Trustee hereunder, will survive such discharge. The
     Company will reimburse the trust fund for any loss
     suffered by it as a result of any tax, fee or other charge
     imposed on or assessed against deposited U.S. Government
     Obligations or Foreign Government Securities, as the case
     may be, or any principal, premium or interest paid on such
     Obligations, and, subject to the provisions of Section
     605, will indemnify the Trustee against any claims made
     against the Trustee in connection with any such loss.

              "Foreign Government Securities" as used in
     Section 403 means, with respect to Securities and Coupons,
     if any, of any series that are denominated in a Foreign
     Currency, securities that are (i) direct obligations of
     the government that issued such currency for the payment
     of which obligations its full faith and credit is pledged
     or (ii) obligations of a Person controlled or supervised
     by and acting as an agency or instrumentality of such
     government (the timely payment of which is unconditionally
     guaranteed as a full faith and credit obligation of such
     government) which, in either case under clauses (i) or
     (ii), are not callable or redeemable at the option of the
     issuer thereof and will also include a depository receipt
     issued by a bank or trust company as custodian with
     respect to any such Foreign Government Obligation or a
     specified payment of interest on or principal of any such
     Foreign Government Obligation held by such custodian for
     the account of the holder of a depository receipt;
     provided that (except as required by law) such custodian
     is not authorized to make any deduction from the amount
     payable to the holder of such depository receipt from any
     amount received by the custodian in respect of the Foreign
     Government Obligations or the specific payment of interest
     on or principal of the Foreign Government Obligation
     evidenced by such depository receipt.

              "U.S. Government Obligations" means securities
     that are (i) direct obligations of the United States of
     America for the payment of which its full faith and credit
     is pledged or (ii) obligations of a Person controlled or
     supervised by and acting as an agency or instrumentality
     of the United States of America the timely payment of
     which is unconditionally guaranteed as a full faith and
     credit obligation of the United States of America, which,
     in either case under clauses (i) or (ii), are not callable
     or redeemable at the option of the issuer thereof and will
     also include a depository receipt issued by a bank or
     trust company as custodian with respect to any such U.S.
     Government Obligation or a specified payment of interest
     on or principal of any such U.S. Government Obligation
     held by such custodian for the account of the holder of a
     depository receipt; provided that (except as required by
     law) such custodian is not authorized to make any
     deduction from the amount payable to the holder of such
     depository receipt from any amount received by the
     custodian in respect of the U.S. Government Obligations or
     the specific payment of interest on or principal of the
     U.S. Government Obligation evidenced by such depository
     receipt.

     respect to Securities of that series.

     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 in every such case the Trustee or the
     Holders of not less than 331/3% in principal amount of the
     Outstanding Securities of that series may declare the
     principal amount (or, if the Securities of that series are
     Original Issue Discount Securities, such portion of the
     principal amount as may be specified in the terms of that
     series) of all of 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 Holders), and upon
     any such declaration such principal amount (or specified
     amount) shall become immediately due and payable.

              At any time after such a declaration 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 and its
     consequences if:

              (1)  the Company has paid or deposited with the
     Trustee a sum sufficient to pay:
<PAGE 40>

                     any interest on and Additional Amounts
                     with respect to all Securities of that
                     series and any Coupons appertaining thereto;

                          (B)    the principal of (and premium,
                     if any, on) any Securities of that series
                     which have become due otherwise than by
                     such declaration of acceleration and
                     interest thereon and any Additional
                     Amounts with respect thereto at the rate
                     or rates prescribed therefor in such
                     Securities;

                          (C)    to the extent that payment of
                     such interest or Additional Amounts is
                     lawful, interest upon overdue installments
                     of any interest and Additional Amounts at
                     the rate or rates prescribed therefor 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 non-payment of
     the principal of (and premium, if any,) and interest on,
     and any Additional Amounts with respect to 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 or any Additional Amounts with
     respect to any Security or Coupon, if any, when such
     interest or Additional Amounts become 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, if any, on) any Security at the
     Maturity thereof;

     the Company will, upon demand of the Trustee, pay to the
     Trustee, for the benefit of the Holders of such Securities
     or Coupons, if any, the whole amount of Money then due and
     payable on such Securities and any Coupons for principal
     (and premium, if any) and interest and, to the extent that
     payment of such interest shall be legally enforceable,
     interest on any overdue principal (and premium, if any)
     and on any overdue interest and Additional Amounts, at the
     rate or rates prescribed therefor in such Securities or
     Coupons, if any, and, in addition thereto, such further
     amount of Money 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.
<PAGE 41>

              If the Company fails to pay the Money and is
     required to pay the Trustee pursuant to the preceding
     paragraph forthwith upon the demand of the Trustee, the
     Trustee in its own name and as trustee of an express
     trust, may institute a judicial proceeding for the
     collection of the Money 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 or Coupons, if any, and
     collect the Money adjudged or decreed to be paid in the
     manner provided by law out of the property of the Company
     or any other obligor upon such Securities or Coupons, if
     any, 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
     or Coupons, if any, 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 such
     other obligor or their creditors, the Trustee
     (irrespective of whether the principal of the Securities
     shall then be due and payable as therein expressed or by
     declaration or otherwise and irrespective of whether the
     Trustee shall have made any demand on the Company for the
     payment of any overdue principal, premium, interest or
     Additional Amounts) 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 the principal and any
     premium, interest and Additional Amounts owing and unpaid
     in respect of the Securities and any Coupons appertaining
     thereto 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 or counsel) and of the Holders of
     Securities or any Coupons allowed in such judicial
     proceeding; and

              (ii)   to collect and receive any Monies or other
     property payable or deliverable on any such claims and to

     such judicial proceeding is hereby authorized by each
     Holder of Securities or any 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 of Securities or any Coupons, to pay to the
     Trustee any amount due to it for the reasonable
     compensation, expenses, disbursements and advances of the
     Trustee, its agents and counsel and any other amounts due
     the Trustee under Section 605.

              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 any
     Coupon any plan of reorganization, arrangement, adjustment

     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 or judgment shall, after provision for
     the payment of the reasonable compensation, expense,
     disbursements and advances of the Trustee, its agents and
     counsel, and for any other amounts due to the Trustee
     under Section 605, be for the ratable benefit of the
     Holders of the Securities or any Coupons in respect of
     which such judgment has been recovered.

              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, if any) or interest or Additional Amounts, 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
             605; and

              Second: To the payment of the amounts then due

             benefit of which such Money has been collected,
             ratably, without preference or priority of any
             kind, according to the amounts due and payable on
             such Securities and any Coupons for principal (and
             premium, if any) and interest and Additional
             Amounts, respectively; and

              Third: The balance, if any, to the Person or
     Persons entitled thereto.

     SECTION 507.    Limitation on Suits.

              No Holder of any Security of any series or any
     Coupons appertaining thereto 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

              (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;
<PAGE 43>

              (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 reasonable indemnity 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 or any Security to affect, disturb or prejudice
     the rights of any other of such Holders or Holders of
     Securities of any other series, 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 of such Holders.

     SECTION 508.    Unconditional Right of Holders to Receive
                     Principal and any Premium, Interest and
                     Additional Amounts.

              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, any premium and (subject to
     Sections 305 and 307) interest on, and any Additional
     Amounts with respect to such Security or payment of such
     Coupon, as the case may be, on the respective Stated
     Maturity or Maturities therefor specified in such Security
     or Coupon (or, in the case of redemption, on the
     Redemption Date or, in the case of repayment at the option
     of such Holder if provided in or pursuant to this
     Indenture, on the date such repayment is due) and to
     institute suit for the enforcement of any such payment,
     and such right shall not be impaired without the consent
     of such Holder.

     SECTION 509.    Restoration of Rights and Remedies.

              If the Trustee or any Holder 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, subject to any determination in such proceeding, the
     Company, the Trustee and each such Holder shall be
     restored severally and respectively to their former
     positions hereunder and thereafter all rights and remedies
     of the Trustee and each such Holder 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 is intended to
     be exclusive of any other right or remedy, and every right
<PAGE 44>

     and remedy shall, to the extent permitted by law, be
     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
     such Holder, as the case may be.

     SECTION 512.    Control by Holders.

              The Holders of 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 and any
     Coupons appertaining thereto, 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)  such direction is not unduly prejudicial to
     the rights of the other Holders of Securities of such
     series not joining in such action.

     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 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, if any) or interest on any Security of such
     series or any Coupons appertaining thereto, 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 impair any right consequent
     thereon.
<PAGE 45>

     SECTION 514.    Waiver of 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 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.    Judgment Currency.

              The following provisions of this Section 515
     shall apply to the extent permissible under applicable
     law: Judgments in respect of any obligations of the
     Company under any Securities or Coupons, if any, of any
     series shall be rendered in the currency or currency unit
     in which such Securities or Coupons are payable.  If for
     the purpose of obtaining a judgment in any court with
     respect to any obligation of the Company hereunder or
     under any Security or Coupon, it shall become necessary to
     convert into any other currency or currency unit any
     amount in the currency or currency unit due hereunder or
     under such Security or Coupon, then such conversion shall
     be made at the Conversion Rate (as defined below) as in
     effect on the date the Company shall make payment to any
     person in satisfaction of such judgment. If pursuant to
     any such judgment, conversion shall be made on a date
     other than the date payment is made and there shall occur
     a change between such Conversion Rate and the Conversion
     Rate as in effect on the date of payment, the Company
     agrees to pay such additional amounts (if any) as may be
     necessary to ensure that the amount paid is the amount in
     such other currency or currency unit which, when converted
     at the Conversion Rate as in effect on the date of payment
     or distribution, is the amount then due hereunder or under
     such Security or Coupon. Any amount due from the Company
     under this Section 515 shall be due as a separate debt and
     is not to be affected by or merged into any judgment being
     obtained for any other sums due hereunder or in respect of
     any Security or Coupon so that in any event the Company's
     obligations hereunder or under such Security or Coupon
     will be effectively maintained as obligations in such
     currency or currency unit. In no event, however, shall the
     Company be required to pay more in the currency or
     currency unit due hereunder or under such Security or
     Coupon at the Conversion Rate as in effect when payment is
     made than the amount of currency or currency unit stated
     to be due hereunder or under such Security or Coupon.

              For purposes of this Section 515, "Conversion
     Rate" shall mean the spot rate as determined by the
     Company at which in accordance with normal banking
     procedures the currency or currency unit into which an
     amount due hereunder or under any Security or Coupon is to
     be converted could be purchased with the currency or
     currency unit due hereunder or under any Security or
     Coupon, at the option of the Company from major banks
     located in New York, London or any other principal market
     for such purchased currency or currency unit.

                                THE TRUSTEE

     SECTION 601.    Certain Rights of Trustee.

              Subject to the provisions of the Trust Indenture
     Act:

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

              (b)    any request or direction of the Company
     mentioned herein shall be sufficiently evidenced by a
     Company Request or Company Order (in each case, 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;

              (c)    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;

              (d)    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;

              (e)    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 pursuant to this Indenture, unless such Holders
     shall have offered to the Trustee reasonable security or
     indemnity against the costs, expenses and liabilities
     which might be incurred by it in compliance with such
     request or direction;

              (f)    the Trustee shall not be bound to make any
     investigation into the facts or matters stated in any
     resolution, certificate, statement, instrument, opinion,
     report, notice, request, direction, consent, order, bond,
     debenture, note, other evidence of indebtedness or other
     paper or document, but 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 examine the books, records and
     premises of the Company, personally or by agent or attorney;

              (g)    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;
<PAGE 47>

              (h)    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;

              (i)    prior to the occurrence of an Event of
     Default of which it has or is deemed to have notice
     hereunder, and after the curing or waiver of any Event of
     Default which may have occurred, the Trustee undertakes to
     perform 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

              (j)    the Trustee shall not be required to take
     notice of or be deemed to have notice of any default or
     Event of Default hereunder unless a Responsible Officer of
     the Trustee has actual knowledge thereof, and in the
     absence of any such notice, the Trustee may conclusively
     assume that no such default or Event of Default exists.

     SECTION 602.    Not Responsible for Recitals or Issuance
                     of Securities.

              The recitals contained herein and in the
     Securities, except the Trustee's certificates of
     authentication, 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
     the sufficiency of this Indenture or of the Securities or
     the 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 603.    May Hold Securities.

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

     SECTION 604.    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 605.    Compensation and Reimbursement.

              The Company agrees:
<PAGE 48>

              (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);

              (2)  except as otherwise expressly provided
     herein, to reimburse the 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 expenses and disbursements of its agents and counsel),
     except any such expense, disbursement or advance as may be
     attributable to the Trustee's negligence or bad faith; and

              (3)  to indemnify the Trustee and its agents for,
     and to hold it harmless against, any loss, liability or
     expense incurred without negligence or bad faith on their
     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 themselves
     against any claim or liability in connection with the
     exercise or performance of any of their powers or duties
     hereunder.

              As security for the performance of the
     obligations of the Company under this Section, the Trustee
     shall have a lien prior to the Securities of any series
     upon all property and funds held or collected by the
     Trustee as such, except funds held in trust for the
     payment of principal of, and premium or interest on or any
     Additional Amounts with respect to Securities or any
     Coupons appertaining thereto.

              The obligations of the Company under this Section
     605 to compensate and indemnify the Trustee and to pay or
     reimburse the Trustee and each predecessor Trustee for
     expenses, disbursements and advances shall constitute
     additional indebtedness hereunder and shall survive the
     satisfaction and discharge of this Indenture.

     SECTION 606.    Resignation and Removal; Appointment of
                     Successor.

              (a)    No resignation or removal of the Trustee
     and no appointment of a successor Trustee pursuant to this
     Article shall become effective until the acceptance of
     appointment by the successor Trustee pursuant to Section 607.

              (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 the instrument
     of acceptance by a successor Trustee required by Section
     607 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
     with respect to the Securities of such series.

              (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:
<PAGE 49>

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

                          (2)    the Trustee shall cease to be
                     eligible under Section 310(a) of the Trust
                     Indenture Act and shall fail to resign
                     after written request therefor by the
                     Company or by any such Holder, or

                          (3)    the Trustee shall become
                     incapable of acting or shall be adjudged a
                     bankrupt or insolvent or a receiver of the
                     Trustee or 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 a Board
     Resolution may remove the Trustee with respect to all
     Securities or the Securities of such series, or (ii) 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
     removal of the Trustee with respect to all Securities of
     such series 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 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) and shall comply with
     the applicable requirements of Section 607.  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 in accordance with the
     applicable requirements of Section 607, become the
     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 and accepted
     appointment in the manner required by Section 607, 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 the
     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 in Section 105. 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 607.    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
     hereunder of the retiring Trustee; but, on the request of
     the Company or the successor Trustee, all property and
     Money held by 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 605.

                      (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 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 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 that
     no Trustee shall be responsible for any notice given to,
     or received by, or any act or failure to act on the part
     of any other Trustee hereunder; and upon the execution and
     delivery of such supplemental indenture the resignation or
     removal of the retiring Trustee shall become effective to
     the extent provided therein 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, as
     the case may be.
<PAGE 51>

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

     SECTION 608.    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 shall have been
     authenticated, but not delivered, by the Trustee then in
     office, any successor by merger, conversion or
     consolidation to such authenticating Trustee may adopt
     such authentication and deliver the Securities so
     authenticated with the same effect as if such successor
     Trustee had itself authenticated such Securities.

     SECTION 609.    Corporate Trustee Required; Eligibility.

              There shall at all times be a Trustee hereunder
     that is a Corporation permitted by the Trust Indenture Act
     to act as trustee under an indenture qualified under the
     Trust Indenture Act and that has a combined capital and
     surplus (computed in accordance with Section 310(a)(2) of
     the Trust Indenture Act) of at least $50,000,000. 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.

     SECTION 610.    Appointment of Authenticating Agent.

              The Trustee may appoint one or more
     Authenticating Agents acceptable to the Company with
     respect to one or more series of Securities which shall be
     authorized to act on behalf of the Trustee to authenticate
     Securities of that or those series issued upon original
     issue, exchange, registration of transfer, partial
     redemption or pursuant to Section 306, 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.
     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, except as provided in or pursuant to this
     Indenture, shall at all times be a corporation that would
     be permitted by the Trust Indenture Act to act as trustee
     under an indenture qualified under the Trust Indenture
     Act, is authorized under applicable law and by its charter
     to act as an Authenticating Agent and has a combined
     capital and surplus (computed in accordance with Section
     310(a)(2) of the Trust Indenture Act) of at least
     $50,000,000. If at any time an Authenticating Agent shall
     cease to be eligible in accordance with the provisions of
     this Section, it shall resign immediately in the manner
     and with the effect specified in this Section.
<PAGE 52>

              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 be the
     successor of such Authenticating Agent hereunder, provided
     such corporation shall be otherwise eligible under this
     Section, without the execution or filing of any paper or
     any further act on the part of the Trustee or the
     Authenticating Agent.

              An Authenticating Agent may resign at any time by
     giving written notice thereof to the Trustee and the
     Company. The Trustee may at any time terminate the agency
     of an Authenticating Agent by giving written notice
     thereof to such Authenticating Agent and 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 may appoint a
     successor Authenticating Agent which shall be acceptable
     to the Company and shall (i) mail written notice of such
     appointment by first-class mail, postage prepaid, to all
     Holders of Registered Securities, if any, of the series
     with respect to which such Authenticating Agent shall
     serve, as their names and addresses appear in the Security
     Register, and (ii) if Securities of the series are issued
     as Bearer Securities, publish notice of such appointment
     at least once in an Authorized Newspaper in the place
     where such successor Authenticating Agent has its
     principal office if such office is located outside the
     United States. 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. No successor
     Authenticating Agent shall be appointed unless eligible
     under the provisions of this Section.

              The Company agrees to pay each Authenticating
     Agent from time to time reasonable compensation for its
     services under this Section. If the Trustee makes such
     payments, it shall be entitled to be reimbursed for such
     payments, subject to the provisions of Section 605.

              The provisions of Sections 308, 602 and 603 shall
     be applicable to each Authenticating Agent.

              If an Authenticating Agent is appointed with
     respect to one or more series of Securities pursuant to
     this Section, the Securities of such series may have
     endorsed thereon, in addition to or in lieu of the
     Trustee's certificate of authentication, an alternate
     certificate of authentication in the following form:

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

                                 BANK ONE, NA
                                 As Trustee

                                 By

                                     As Authenticating Agent

                                 By

                                     Authorized Signatory
<PAGE 53>

              If all of the Securities of any series may not be
     originally issued at one time, and if the Trustee does not
     have an office capable of authenticating Securities upon
     original issuance located in a Place of Payment where the
     Company wishes to have Securities of such series
     authenticated upon original issuance, the Trustee, if so
     requested in writing (which writing need not be
     accompanied by or contained in an Officers' Certificate by
     the Company), shall appoint in accordance with this
     Section an Authenticating Agent having an office in a
     Place of Payment designated by the Company with respect to
     such series of Securities.

     SECTION 611.    Notice of Defaults.

              The Trustee shall, within 90 days after the
     occurrence of a default with respect to the Securities of
     any series, mail to all Holders of Securities of that
     series entitled to receive reports pursuant to Section
     703, notice of all defaults with respect to that series
     known to the Trustee, unless such defaults have been cured
     before the giving of such notice; provided, however, that,
     except in the case of default in the payment of the
     principal of, premium, if any, or interest on any of the
     Securities of such series or in the making of any sinking
     fund payment with respect to such series, the Trustee
     shall be protected in withholding such notice if and so
     long as the Board of Directors or Responsible Officers of
     the Trustee in good faith determines that the withholding
     of such notice is in the interests of the Holders of
     Securities of such series. 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.

     receiving and holding the same, agrees with the Company

     of a lease, the predecessor Person shall be relieved of

     Securities and the Coupons.

     premium, if any, or interest, if any, on Bearer Securities
     or Coupons, if any;

              (11)  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, provided such action shall
     not adversely affect the interests of the Holders of
     Securities of any series or any Coupons appertaining
     thereto in any material respect;

              (12)  to add to, delete from or revise the

     SECTION 902.    Supplemental Indentures with Consent of
                     Holders.

              With the consent of the Holders of not less than
     a majority in principal amount of the Securities
     Outstanding of each series affected by such supplemental
     indenture, by Act of such Holders delivered to the Company
     and the Trustee, the Company, when authorized by a Board

     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 of such
     series under this Indenture; provided, however, that no
     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 any installment of principal of or interest on any
     Additional Amounts with respect to, any Security, or
     reduce the principal amount thereof or the rate of
     interest thereon or any Additional Amounts with respect
     thereto, or any premium payable upon the redemption
     thereof or otherwise, or reduce the amount of the
     principal of an Original Issue Discount Security that

     redemption, on or after the Redemption Date or, in the
     case of repayment at the option of the Holder, on or after
     the date for repayment), or

              (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

     the requirements of Section 1504 for quorum or voting, or

              (3)  change any obligation of the Company to
     maintain an office or agency in the places and for the
     purposes specified in Section 1002, or

              (4)  modify any of the provisions of this Section
     902, Section 513, or Section 1008, except to increase any
     such percentage or to provide with respect to any
     particular series the right to condition the effectiveness
     of any supplemental indenture as to that series on the
     consent of the Holders of a specified percentage of the
     aggregate principal amount of Outstanding Securities of
     such series (which provision may be made pursuant to
     Section 301 without the consent of any Holder) or to
     provide that certain other 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

              (5)  modify any of the provisions of Section 1007.

              For the purposes of this Section 902, if the

     warrants, any holder of an unexercised and unexpired
     warrant with respect to such series shall not be deemed to
     be a Holder of Outstanding Securities of such series in
     the amount issuable upon the exercise of such warrants.

              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.

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

     SECTION 903.    Execution of Supplemental Indentures.

              As a condition to executing, or accepting the
     additional trusts created by, any supplemental indenture
     permitted by this Article or the modifications 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 and an Officers'
     Certificate each 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 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, including any Coupons, 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 Company shall so
     determine, new Securities including any Coupons 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 including any Coupons of such series.

                                ARTICLE TEN

                                 COVENANTS

     SECTION 1001.   Payment of Principal, Premium and Interest
                     and Additional Amounts.

              The Company covenants and agrees for the benefit
     of the Holders of each series of Securities that it will
     duly and punctually pay the principal of (and premium, if
     any) and interest on and any Additional Amounts with
     respect to the Securities of that series in accordance
     with the terms of the Securities and this Indenture.

              The interest on Securities with Coupons
     appertaining thereto shall be payable only upon
     presentation and surrender of the several Coupons for such
     interest installments as are evidenced thereby as they
     severally mature. The interest, if any, on any temporary
     Bearer Security shall be paid, as to any installment of
     interest evidenced by a Coupon attached thereto only upon
     presentation and surrender of such Coupon and, as to other
     installments of interest, only upon presentation of such
     Security for notation thereon of the payment of such
     interest.

     SECTION 1002.   Maintenance of Office or Agency.

              If Securities of a series are issued as
     Registered Securities, the Company will maintain in each
     Place of Payment for any series of Securities an office or
     agency where Securities and Coupons, if any of that series
     may be presented or surrendered for payment, 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 an office or agency,
     (A) subject to any laws or regulations applicable thereto,
     in a Place of Payment for that series which is located
     outside the United States, where Securities of that series
     and related coupons may be presented and surrendered for
     payment; provided, however, that if the Securities of that
     series are listed on The International Stock Exchange of
     the United Kingdom and the Republic of Ireland Limited,
     the Luxembourg Stock Exchange or any other stock exchange
     located outside the United States and such stock exchange
     shall so require, the Company will maintain a Paying Agent
     for the Securities of that series in London, Luxembourg or
     any other 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 (B) subject to any
     laws or regulations applicable thereto, in a Place of
     Payment for that series located outside the United States,
     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 any such office or agency. If
     at any time the Company shall fail to maintain any such
     required office or agency or shall fail to furnish the
     Trustee with the address thereof, such presentations,
     surrenders, notices and demands may be made or served at
     the Corporate Trust Office of the Trustee, except that
     Bearer Securities of such series and any Coupons
     appertaining thereto may be presented and surrendered for
     payment at the place specified for the purpose with
     respect to such Securities as provided in or pursuant to
     this Indenture, and the Company hereby appoints the
     Trustee as its agent to receive all such presentations,
     surrenders, notices and demands.
<PAGE 61>

              Except as otherwise provided in or pursuant to
     this Indenture, no payment of principal or interest on
     Bearer Securities shall be made at any office or agency of
     the Company in the United States, by check mailed to any
     address in the United States, by transfer to an account
     located in the United States or upon presentation or
     surrender in the United States of a Bearer Security or
     coupon for payment, even if the payment would be credited
     to an account located outside the United States; provided,
     however, that, if the Securities of a series are
     denominated and payable in Dollars, payment of principal
     of and any interest on or any Additional Amounts with
     respect to any such Bearer Security shall be made at the
     office of the Company's Paying Agent in Chicago, Illinois
     or in the event that certificated senior notes are issued
     or if The Depositary Trust Company shall so require, the
     Company will be required to appoint a paying agent and
     security registrar in the City of New York if (but only
     if) payment in Dollars of the full amount of such
     principal, interest or Additional Amounts, 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 also from time to time designate
     one or more other offices or agencies where the Securities
     (including any Coupons, if any) of one or more series may
     be presented or surrendered for any or all such purposes
     and may from time to time rescind such designations;
     provided, however, that no such designation or rescission
     shall in any manner relieve the Company of its obligation
     to maintain an office or agency in each Place of Payment
     for Securities (including any Coupons, if any) 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 provided in or
     pursuant to this Indenture, the Company hereby designates
     as the Place of Payment for each series as Chicago,
     Illinois and initially appoints the office or agency of
     the Corporate Trust Office of the Trustee for such
     purpose.  In the event that certificated senior notes are
     issued or if The Depositary Trust Company shall so
     require, the Company will appoint a paying agent and
     security registrar in the City of New York.  Pursuant to
     Section 301(6) of this Indenture, the Company may
     subsequently appoint a place or places in addition to or
     other than Chicago, Illinois where such Securities may be
     payable.

     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 Securities, it
     shall, on or before each due date of the principal of (and
     premium, if any) or interest on or any Additional Amounts
     with respect to any of the Securities of that series,
     segregate and hold in trust for the benefit of the Persons
     entitled thereto a sum of Money sufficient to pay the
     principal (and premium, if any), interest or Additional
     Amounts so becoming due until such sums shall be paid to
     such Persons or otherwise disposed of as herein provided
     and shall 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, it shall, on
     or prior to (but in the case of payments to be made at a
     Place of Payment outside of the United States, its
     territories, possessions and areas subject to its
     jurisdiction, at least one New York Business Day before)
     each due date of the principal of, any premium or interest
     on or any Additional Amounts with respect to any
     Securities of such series, deposit with any Paying Agent a
     sum of Money sufficient to pay the principal or any
     premium, interest or Additional Amounts so becoming due,
<PAGE 62>

     such sum to be held in trust for the benefit of the
     Persons entitled thereto, and (unless such Paying Agent is
     the Trustee) the Company shall promptly notify the Trustee
     of its action or failure so to act.

              The Company shall 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 shall:

              (1)  hold all sums held by it for the payment of
     the principal of (and premium, if any) or interest on or
     any Additional Amounts with respect to Securities of that
     series 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 of
     that series) in the making of any payment of principal
     (and premium, if any) or interest on or any Additional
     Amounts with respect to the Securities of such 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 Money.

              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, if any) or
     interest on or any Additional Amounts with respect to any
     Security of any series and remaining unclaimed for 2 years
     after such principal (and premium, if any) or interest or
     Additional Amounts shall have become due and Payable shall
     be paid to the Company on Company Request, or (if then
     held by the Company) shall be discharged from such trust;
     and the Holder of such Security and Coupon, if any, shall
     thereafter, as an unsecured general creditor, look only to
     the Company for payment thereof, and all liability of the
     Trustee or such Paying Agent with respect to such Money,
     and all liability of the Company as trustee thereof, shall
     thereupon cease; provided, however, that the Trustee or
     such Paying Agent, before being required to make any such
     repayment, may at the expense of the Company cause to be
     published once, in an Authorized Newspaper in each Place
     of Payment for such series or to be mailed to Holders of
     Registered Securities of such series 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 or mailing nor shall it be later
     than 2 years after such principal and any premium or
     interest or Additional Amounts shall have become due and
     payable, any unclaimed balance of such Money then
     remaining will be repaid to the Company.
<PAGE 63>

     SECTION 1004.   Additional Amounts.

              If any Securities of a series provide for the
     payment of Additional Amounts, the Company agrees to pay
     to the Holder of any such Security or any Coupon
     appertaining thereto Additional Amounts as provided
     therein. Whenever in this Indenture there is mentioned, in
     any context, the payment of the principal of or any
     premium or interest on, or in respect of, any Security of
     any series or any Coupon or the net proceeds received on
     the sale or exchange of any Security of any series, such
     mention shall be deemed to include mention of the payment
     of Additional Amounts provided by the terms of such series
     established hereby or pursuant hereto to the extent that,
     in such context, Additional Amounts are, were or would be
     payable in respect thereof pursuant to such terms and
     express mention of the payment of Additional Amounts (if
     applicable) in any provision hereof shall not be construed
     as excluding Additional Amounts in those provisions hereof
     where such express mention is not made.

              Except as otherwise provided in or pursuant to
     this Indenture, if the Securities of a series provide for
     the payment of Additional Amounts, at least 10 days prior
     to the first Interest Payment Date with respect to such
     series of Securities (or if the Securities of such series
     shall not bear interest prior to Maturity, the first day
     on which a payment of principal is made), and at least 10
     days prior to each date of payment of principal or
     interest if there has been any change with respect to the
     matters set forth in the below-mentioned Officers'
     Certificate, the Company shall furnish to the Trustee and
     the principal Paying Agent or Paying Agents, if other than
     the Trustee, an Officers' Certificate instructing the
     Trustee and such Paying Agent or Paying Agents whether
     such payment of principal of or interest on the Securities
     of such series shall be made to Holders of Securities of
     such series or the Coupons appertaining thereto who are
     United States Aliens without withholding for or on account
     of any tax, assessment or other governmental charge
     described in the Securities of such series. If any such
     withholding shall be required, then such Officers'
     Certificate shall specify by country the amount, if any,
     required to be withheld on such payments to such Holders
     of Securities or Coupons and the Company agrees to pay to
     the Trustee or such Paying Agent the Additional Amounts
     required by the terms of such Securities. The Company
     covenants to indemnify the Trustee and any Paying Agent
     for, and to hold them harmless against, any loss,
     liability or expense reasonably incurred without
     negligence or bad faith on their part arising out of or in
     connection with actions taken or omitted by any of them in
     reliance on any Officers' Certificate furnished pursuant
     to this Section.

     SECTION 1005.   Corporate Existence.

              Subject to Article Eight, the Company will do or
     cause to be done all things necessary to preserve and keep
     in full force and effect its corporate existence, rights
     (charter and statutory) and franchises; provided, however,
     that the Company shall not be required to preserve any
     such right or franchise if the Board of Directors shall
     determine that the preservation thereof is no longer
     desirable in the conduct of the business of the Company
     and that the loss thereof is not disadvantageous in any
     material respect to the Holders.
<PAGE 64>

     SECTION 1006.   Limitation on Liens.

              Except as hereinafter in this Section 1006
     expressly permitted and as permitted by Section 801, so
     long as any of the Securities remain Outstanding, the
     Company will not at any time directly or indirectly
     create, assume or suffer to exist, and will not cause,
     suffer or permit any Subsidiary to create, assume or
     suffer to exist, otherwise than in favor of the Company or
     a Subsidiary, any mortgage, pledge, lien, encumbrance of
     or upon or security interest (collectively, "Liens") upon
     any of its properties or assets, real, personal or mixed,
     whether owned at the date of this Indenture or thereafter
     acquired, or of or upon, any income or profits therefrom,
     without making effective provision, and the Company
     covenants that in any such case it will make or cause to
     be made effective provision, whereby the Securities then
     or thereafter Outstanding shall be secured by such Liens
     equally and ratably with any and all other obligations and
     indebtedness thereby secured, so long as any such other
     obligations or indebtedness shall be so secured.

              Nothing in this Section 1006 shall be construed
     to prevent the Company or any Subsidiary from creating,
     assuming or suffering to exist Liens of the following
     character, to all of which the provisions of the first
     paragraph of this Section 1006 shall not be applicable:

     provided that such Lien shall extend only to the property
     so acquired, improvements thereon, replacements thereof
     and the income or profits therefrom;

              (c)    Liens on any property at the time of the
     acquisition thereof, whether or not assumed by the Company

     to the property so acquired, improvements thereon,
     replacements thereof and the income or profits therefrom;

              (d)    Liens on any property or any contract for

     completion of such construction, or (ii) commencement of
     operation of such property, whichever is later; provided
     that such Lien shall extend only to the property so
     acquired or constructed, improvements thereon,

     "investment" means any equity investment in any Person,
     any obligation of any Person for money borrowed or for the
     deferred purchase price of property which is owed to the
     Company or a Subsidiary, as the case may be, and any
     amount advanced to any person by the Company or any
     Subsidiary, excluding, however, current accounts payable

     whole or in part, of any obligation or indebtedness
     secured by any Lien created, existing or assumed in
     accordance with the provisions of Clauses (a) through (h)
     above, inclusive, provided that the principal amount of
     the obligation or indebtedness secured by such refunding
     or extended Liens shall not exceed the principal amount of
     the obligation or indebtedness to be refunded or extended
     outstanding at the time of such refunding or extension,
     together with related financing costs, and that such
     refunding or extended Liens shall be limited in lien to
     the same property that secured the obligation or
     indebtedness refunded or extended, and property
     substituted therefor and property acquired after the date
     thereof and subject to the lien thereof, in accordance
     with the provisions of such refunding or extension;

              (j)    Liens on any office equipment or data

     stayed and which has been appealed and secured, if
     necessary, by the filing of an appeal bond; and liens for
     taxes or assessments for the current year or which are not
     due or which remain payable without penalty or which are

     with or the giving of any form of security to any
     governmental agency or any body created or approved by law

     connection with the financing of the acquisition or

     charges incidental to construction or maintenance; or

<PAGE 67>

              If at any time the Company or any Subsidiary
     shall create or assume any Lien to which the covenant in
     the first paragraph of this Section 1006 is applicable,
     the Company will promptly deliver to the Trustee an
     Officers' Certificate, stating that such covenant has been
     complied with, and an Opinion of Counsel, stating that in
     his opinion such covenant has been complied with and that
     any instruments executed by the Company or any Subsidiary
     in the performance of such covenant complied with the
     requirements thereof.

              In the event that the Company or any Subsidiary
     shall hereafter secure the Securities equally and ratably
     with any other obligation or indebtedness pursuant to the
     provisions of this Section 1006, the Trustee is hereby
     authorized to enter into an indenture supplemental hereto
     and to take such action, if any, as it may deem advisable
     to enable it to enforce effectively the rights of the
     Holders of the Securities so secured, equally and ratably
     with such other obligation or indebtedness.

              The Trustee may accept an Officers' Certificate
     and Opinion of Counsel as conclusive evidence that any
     such supplemental indenture or steps taken to secure the
     Securities equally and ratably comply with the provisions
     of this Section 1006.

     SECTION 1007.   Change of Control.

              If this Section is specified, as contemplated by
     Section 301, to be applicable to Securities and Coupons,
     if any, of any series, and if a Change of Control occurs
     and is accompanied by a Rating Decline (together, a
     "Change of Control Triggering Event"), each Holder of
     Securities of such series will have the right to require
     the Company to offer to repurchase all or any part (equal
     to $1,000 or an integral multiple thereof) of such
     Holder's Securities at a purchase price in cash equal to
     the principal amount of such Securities plus accrued and
     unpaid interest, if any, to the date of purchase.

              Within 30 days following any Change of Control
     Triggering Event, the Company will mail a notice (the
     "Change of Control Offer") to each Holder of Securities of
     such series with a copy to the Trustee stating:

              (a)    that a Change of Control Triggering Event
     has occurred and that such Holder has the right to require
     the Company to purchase such Holder's Securities at a
     purchase price in cash equal to the principal amount of
     such Securities plus accrued and unpaid interest, if any,
     to the date of purchase (the "Change of Control Payment");

              (b)     the repurchase date (which shall be no
     earlier than 30 days nor later than 60 days from the date
     such notice is mailed) (the "Change of Control Payment
     Date"); and

              (c)    the procedures determined by the Company,
     consistent with the Indenture, that a Holder must follow
     in order to have its Securities repurchased.

              On the Change of Control Payment Date with
     respect to the Securities of any series, the Company will,
     to the extent lawful:
<PAGE 68>

              (a)    accept for payment all Securities of such
     series or portions thereof (in integral multiples of
     $1,000) properly tendered and not withdrawn under the
     Change of Control Offer;

              (b)    deposit with the paying agent an amount
     equal to the Change of Control Payment in respect of all
     Securities of such series or portions thereof so tendered;
     and

              (c)    deliver or cause to be delivered to the
     Trustee the Securities of such series so accepted together
     with an Officers' Certificate stating the aggregate
     principal amount of such Securities or portions thereof
     being purchased by the Company.

              The Paying Agent will promptly mail to each
     Holder of Securities of any series so tendered the Change
     of Control Payment for such Securities, and the Trustee
     will promptly authenticate and mail (or cause to be
     transferred by book entry) to each Holder a new Security
     equal in principal amount to any unpurchased portion of
     the Securities surrendered, if any; provided that each
     such new Security will be in a principal amount of $1,000
     or an integral multiple of $1,000.

              If the Change of Control Payment Date is on or
     after an interest record date and on or before the related
     interest payment date, any accrued and unpaid interest, if
     any, will be paid to the Person in whose name a Security
     is registered at the close of business on such record
     date, and no additional interest will be payable to
     Holders who tender pursuant to the Change of Control Offer.

              Prior to mailing a Change of Control Offer, and
     as a condition to such mailing (i) the requisite Holders
     of each issue of Indebtedness issued under any indenture
     or other agreement that may be violated by such payment
     shall have consented to such Change of Control Offer being
     made and waived the event of default, if any, caused by
     the Change of Control Triggering Event or (ii) the Company
     will repay all outstanding Indebtedness issued under any
     indenture or other agreement that may be violated by a
     payment to the Holders of Securities under a Change of
     Control Offer or the Company must offer to repay all such
     Indebtedness, and make payment to the holders of such
     Indebtedness that accept such offer and obtain waivers of
     any event of default from the remaining holders of such
     Indebtedness.  The Company covenants to effect such
     repayment or obtain such consent and waiver within 30 days
     following any Change of Control Triggering Event, it being
     an Event of Default if the Company fails to comply with
     such covenant within 30 days after receipt of written
     notice from the Trustee or the Holders of at least 25% in
     principal amount of the Securities of any series.

              The Company will not be required to make a Change
     of Control Offer upon a Change of Control Triggering Event
     if a third party makes the Change of Control Offer in the
     manner, at the times and otherwise in compliance with the
     requirements set forth herein applicable to a Change of
     Control Offer made by the Company and purchases all
     Securities validly tendered and not withdrawn under such
     Change of Control Offer.

     SECTION 1008.   Waiver of Covenant.

              The Company may omit in any particular instance
     to comply with any term, provision or condition set forth
     in Article Eight and Sections 1005 and 1006, if before the
     time for such compliance the Holders of (i) a majority in
     principal amount of the Outstanding Securities or (ii) in
<PAGE 69>

     case less than all of the several series of Securities
     then Outstanding are affected by the omission, at least a
     majority in principal amount of the Outstanding Securities
     of each series so affected voting as a single class shall,
     by Act of such Holders, either waive such compliance in
     such instance or generally waive compliance with such
     term, provision or condition, but no such waiver shall
     extend to or affect such term, provision or condition
     except to the extent so expressly waived, and, until such
     waiver shall become effective, the obligations of the
     Company and the duties of the Trustee in respect of any
     such term, provision or condition shall remain in full
     force and effect.

     SECTION 1009.   Statements as to Compliance; Notice of
                     Certain Defaults.

                      (a)  The Company shall deliver to the
     Trustee, within 120 days after the end of each fiscal
     year, a written statement (which need not be contained in
     or accompanied by an Officers' Certificate) signed by the
     principal executive officer, the principal financial
     officer or the principal accounting officer of the Company
     stating that

              (1)   a review of the activities of the Company
     during such year and of performance under this Indenture
     has been made under his or her supervision, and

              (2)  to the best of his or her knowledge, based
     on such review, (a) the Company has complied with all the
     conditions and covenants imposed on it under this
     Indenture throughout such year, or, if there has been a
     default in the fulfillment of any such condition or
     covenant, specifying each such default known to him or her
     and the nature and status thereof, and (b) no event has
     occurred and is continuing which is, or after notice or
     lapse of time or both would become, an Event of Default,
     or, if such an event has occurred and is continuing,
     specifying each such event known to him and the nature and
     status thereof.

                      (b)  The Company shall deliver to the
     Trustee, within five days after the occurrence thereof,
     written notice of any event which after notice or lapse of
     time or both would become an Event of Default.

                              ARTICLE ELEVEN

                         REDEMPTION OF SECURITIES

     SECTION 1101.   Applicability of Article.

              Securities (including Coupons, if any) of any
     series which are redeemable before their Stated Maturity
     shall be redeemable in accordance with their terms and
     (except as otherwise specified or contemplated by Section
     301 for Securities of any series) in accordance with this
     Article.
<PAGE 70>

     SECTION 1102.   Election to Redeem; Notice to Trustee.

              The election of the Company to redeem any
     Securities (including Coupons, if any) shall be evidenced
     by a Board Resolution. In case of any redemption at the
     election of the Company of all or less than all of the
     Securities (including Coupons, if any) of any series, the
     Company shall, at least 60 days prior to the Redemption
     Date fixed by the Company (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 (including Coupons, if any)
     prior to the expiration of any restriction on such
     redemption provided in the terms of such Securities and
     Coupons, if any, 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 (including
     Coupons, if any) of any series with the same terms are to
     be redeemed, the particular Securities (including Coupons,
     if any) to be redeemed shall be selected not more than 60
     days prior to the Redemption Date by the Trustee, from the
     Outstanding Securities (including Coupons, if any) of such
     series 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 (including Coupons, if any) of that series or
     any integral multiple thereof) of the principal amount of
     Securities (including Coupons, if any) of such series of a
     denomination larger than the minimum authorized
     denomination for Securities of that series.

              The Trustee shall promptly notify the Company in
     writing of the Securities (including Coupons, if any)
     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
     Securities redeemed or to be redeemed only in part, to the
     portion of the principal amount of such Securities which
     has been or is to be redeemed.

     SECTION 1104.   Notice of Redemption.

              Notice of redemption shall be given not less than
     30 nor more than 60 days prior to the Redemption Date,
     unless a shorter period is specified in the Securities to
     be redeemed, to each Holder of Securities to be redeemed,
     as provided in Section 105.

              Each such notice of redemption shall specify the
     Redemption Date, the Redemption Price, the Place or Places
     of Payment, the CUSIP number of such Securities, if any,
     that the Securities of such series are being redeemed at
     the option of the Company pursuant to provisions contained
     in the terms of the Securities of such series or in a
     supplemental indenture establishing such series, if such
     be the case, together with a brief statement of the facts
     permitting such redemption, that payment will be made upon
     presentation and surrender of the applicable Securities,
     that all Coupons, if any, maturing subsequent to the date
<PAGE 71>

     fixed for redemption shall be void, that any interest
     accrued to the Redemption Date will be paid as specified
     in such notice, and that on and after such Redemption Date
     any interest thereon or, in case of partial redemptions,
     on the portions thereof to be redeemed, will cease to
     accrue. If less than all the Securities of any series are
     to be redeemed, the notice of redemption shall specify the
     numbers of the Securities of such series to be redeemed,
     and, if only Bearer Securities of any series are to be
     redeemed and if such Bearer Securities may be exchanged
     for Registered Securities, the last date on which
     exchanges of Bearer Securities for Registered Securities
     not subject to redemption may be made. In case any
     Security of any series is to be redeemed in part only, the
     notice of redemption shall state the portion of the
     principal amount thereof to be redeemed and shall state
     that on and after the Redemption Date, upon surrender of
     such Security and any Coupons appertaining thereto, a new
     Security or Securities of such series in principal amount
     equal to the unredeemed portion thereof and with
     appropriate Coupons will be issued, or, in the case of
     Registered Securities providing appropriate space for such
     notation, at the option of the Holders, the Trustee, in
     lieu of delivering a new Security or Securities as
     aforesaid, may make a notation on such Security of the
     payment of the redeemed portion thereof.

              Notice of redemption of Securities and Coupons,
     if any, 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 before (but in the case of payments to be
     made at a Place of Payment outside of the United States,
     its territories, possessions and areas subject to its
     jurisdiction, at least one New York Business Day before)
     10:00 A.M., New York City time, on any Redemption Date,
     the Company shall deposit in immediately available funds
     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 the relevant currency (or a sufficient number of
     currency units, as the case may be) sufficient to pay the
     Redemption Price of, and (except if the Redemption Date
     shall be an Interest Payment Date) any accrued interest on
     and Additional Amounts with respect to all the Securities
     or portions thereof which are to be redeemed on that date.

     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, and from and after such date
     (unless the Company shall default in the payment of the
     Redemption Price and accrued interest) such Securities
     shall 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. Except as provided in the next succeeding paragraph,
     upon surrender of any such Security (including Coupons, if
     any) for redemption in accordance with such notice, such
     Security shall be paid by the Company at the Redemption
     Price, together with accrued interest and Additional
     Amounts 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 upon presentation and surrender of Coupons
     for such interest (at an Office or Agency located outside
     the United States except as otherwise provided in Section
     1002), and provided, further, that installments of
     interest on Registered Securities whose Stated Maturity is
<PAGE 72>

     on or prior to the Redemption Date shall be payable 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 redemption
     shall not be accompanied by all appurtenant Coupons
     maturing after the Redemption Date, such Bearer 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 Bearer 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 any interest or Additional Amounts
     represented by Coupons shall be payable only upon
     presentation and surrender of those Coupons at an office
     or agency located outside of the United States except as
     otherwise provided pursuant to Sections 901(10) and 1002.

              If any Security called for redemption shall not
     be so paid upon surrender thereof for redemption, the
     principal (and premium, if any) shall, until paid, bear
     interest from the Redemption Date at the rate prescribed
     therefor in the Security.

     SECTION 1107.   Securities Redeemed in Part.

              Any Registered Security (including Coupons, if
     any) which is to be redeemed only in part 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 Registered Security or
     Securities (with appropriate Coupons, if any, attached) of
     the same series, containing identical terms and
     provisions, 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 (including Coupons, if any) so surrendered.
     If a Security in global from is so surrendered, the
     Company shall execute and the Trustee shall authenticate
     and deliver to the U.S. Depository or other depository for
     such Security in global form as shall be specified in the
     Company Order with respect thereto, to the Trustee,
     without service charge, a new Security in global form in a
     denomination equal to and in exchange for the unredeemed
     portion of the principal of the Security in global form 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 Securities of any series is herein
     referred to as an "optional sinking fund payment." If
     provided for by the terms of Securities of any series, the
     cash amount of any sinking fund payment may be subject to
     reduction as provided in Section 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.

     SECTION 1202.   Satisfaction of Sinking Fund Payments with
                     Securities.

              The Company (1) may deliver outstanding
     Securities of a series (other than any previously called
     for redemption or any of such Securities in respect of
     which cash shall have been released to the Company),
     together in the case of any Bearer Securities of such
     series with all unmatured Coupons appertaining thereto,
     and (2) may apply as a credit Securities of a series which
     have been redeemed either at the election of the Company
     pursuant to the terms of such Securities or through the
     application of permitted optional sinking fund payments
     pursuant to the terms of such Securities, in each case in
     satisfaction of all or any part of any sinking fund
     payment with respect to the Securities of such series
     required to be made pursuant to the terms of such
     Securities as provided for by the terms of such series;
     provided that such Securities have not been previously so
     credited. Such Securities shall be received and credited
     for such purpose by the Trustee at the Redemption Price
     specified in such Securities for redemption through
     operation of the sinking fund and the amount of such
     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 any series of Securities, 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 and the portion thereof,
     if any, which is to be satisfied by delivering and
     crediting Securities of that series pursuant to Section
     1202 and will also deliver to the Trustee any Securities
     to be so delivered. Not less than 30 nor more than 60 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
<PAGE 74>

     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.

              Securities of any series which are repayable at
     the option of the Holders thereof before their Stated
     Maturity shall be repaid in accordance with the terms of
     the Securities of such series. The repayment of any
     principal amount of Securities pursuant to such option of
     the Holder to require repayment of Securities before their
     Stated Maturity, for purposes of Section 309, shall not
     operate as a payment, redemption or satisfaction of the
     indebtedness represented by such Securities unless and
     until the Company, at its option, shall deliver or
     surrender the same to the Trustee with a directive that
     such Securities be cancelled. Notwithstanding anything to
     the contrary contained in this Section 1301, in connection
     with any repayment of Securities, the Company may arrange
     for the purchase of any Securities by an agreement with
     one or more investment bankers or other purchasers to
     purchase such Securities by paying to the Holders of such
     Securities on or before the close of business on the
     repayment date an amount not less than the repayment price
     payable by the Company on repayment of such Securities,
     and the obligation of the Company to pay the repayment
     price of such Securities shall be satisfied and discharged
     to the extent such payment is so paid by such purchasers.

              The Company shall provide written notice to the
     Trustee at least 30 days before any tender period related
     to a repayment pursuant to this Section 1301.

                             ARTICLE FOURTEEN

                     SECURITIES IN FOREIGN CURRENCIES

     SECTION 1401.   Applicability of Article.

              Whenever this Indenture provides for (i) any
     action by, or the determination of any of the rights of,
     Holders of Securities of any series in which not all of
     such Securities are denominated in the same Currency, or
     (ii) any distribution to Holders of Securities, in the
     absence of any provision to the contrary in the form of
     Security of any particular series, any amount in respect
     of any Security denominated in a Currency other than
     Dollars shall be treated for any such action or
     distribution as that amount of Dollars that could be
     obtained for such amount at the noon buying rate in the
     City of New York for cable transfers in foreign currencies
     as certified for customs purposes by the Federal Reserve
     Bank of New York and as of the record date with respect to
     Registered Securities of such series (if any) for such
     action, determination of rights or distribution (or, if
     there shall be no applicable record date, such other date
     reasonably proximate to the date of such action,
     determination of rights or distribution) as the Company
     may specify in a written notice to the Trustee.

                              ARTICLE FIFTEEN

                     MEETINGS OF HOLDERS OF SECURITIES

     SECTION 1501.   Purposes for Which Meetings May be Called.

              A meeting of Holders of Securities of such series
     may be called at any time and from time to time pursuant
     to this Article to make, give or take any request, demand,
     authorization, direction, notice, consent, waiver or other
     action provided by this Indenture to be made, given or
     taken by Holders of Securities of such series.

     SECTION 1502.   Call, Notice and Place of Meetings.

              (a)    The Trustee may at any time call a meeting
     of Holders of Securities of any series for any purpose
     specified in Section 1501, to be held at such time and at
     such place in the Borough of Manhattan, The City of New
     York or, if Securities of such series are to be issued as
     Bearer Securities, in London, as the Trustee shall
     determine. Notice of every meeting of Holders of
     Securities of any series, setting forth the time and the
     place of such meeting and in general terms the action
     proposed to be taken at such meeting, shall be given, in
     the manner provided in Section 106, not less than 21 nor
     more than 180 days prior to the date fixed for the meeting.

              (b)    In case at any time the Company (by or
     pursuant to a Board Resolution) or the Holders of at least
     10% 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 the action proposed to
     be taken at the meeting, and the Trustee shall not have
     made the first publication of the notice of such meeting
     within 21 days after receipt of such request or shall not
     thereafter proceed to cause the meeting to be held as
     provided herein, then the Company or the Holders of
     Securities of such series in the amount above specified,
     as the case may be, may determine the time and the place
     in the Borough of Manhattan, The City of New York, or, if
     Securities of such series are to issued as Bearer
     Securities, in London for such meeting and may call such
     meeting for such purposes by giving notice thereof as
     provided in subsection (a) of this Section.

     SECTION 1503.   Persons Entitled to Vote at Meetings.

              To be entitled to vote at any meeting of Holders
     of Securities of any series, a Person shall be (1) a
     Holder of one or more Outstanding Securities of such

     SECTION 1504.   Quorum; Action.

              The Persons entitled to vote a majority in
     principal amount of the Outstanding Securities of a series
     shall constitute a quorum for a meeting of Holders, of
     Securities of such series; provided, however, that if any
     action is to be taken at such meeting with respect to a
     consent or waiver which this Indenture expressly provides
     may be given by the Holders of not less than 662/3% in
     principal amount of the Outstanding Securities of a
     series, the Persons entitled to vote 662/3% in principal
     amount of the Outstanding Securities of such series shall
     constitute a quorum. In the absence of a quorum within 30
     minutes after the time appointed for any such meeting, the
     meeting shall, if convened at the request of Holders of
     Securities of such series, be dissolved. In any other case
     the meeting may be adjourned for a period of not less than
     10 days as determined by the chairman of the meeting prior
     to the adjournment of such meeting. In the absence of a
     quorum at any such adjourned meeting, such adjourned
     meeting may be further adjourned for period of not less
     than 10 days as determined by the chairman of the meeting
     prior to the adjournment of such adjourned meeting. Notice
     of the reconvening of any adjourned meeting shall be given
     as provided in Section 1502(a), except that such notice
     need be given only once not less than five days prior to
     the date on which the meeting is scheduled to be
     reconvened. Notice of the reconvening of an adjourned
     meeting shall state expressly the percentage, as provided
     above, of the principal amount of the Outstanding
     Securities of such series which shall constitute a quorum.

              Except as limited by the proviso to Section 902,
     any resolution represented to a meeting or adjourned
     meeting duly reconvened at which a quorum is present as
     aforesaid may be adopted only by the affirmative vote of
     the Holders of a majority in principal amount of the
     Outstanding Securities of that series; provided, however,
     that, except as limited by the proviso to Section 902, any
     resolution with respect to any consent or waiver which
     this Indenture expressly provides may be given by the
     Holders of not less than 662/3% in principal amount of the
     Outstanding Securities of a series may be adopted at a
     meeting or an adjourned meeting duly convened and at which
     a quorum is present as aforesaid only by the affirmative
     vote of the Holders of 662/3% in principal amount of the
     Outstanding Securities of that series; and provided,
     further, that, 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 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 such series.

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

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

              (a)    Notwithstanding any other provisions of
     this Indenture, the Trustee may make such reasonable
     regulations as it may deem advisable for any meeting of
     Holders of Securities of such 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
<PAGE 77>

     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 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 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 signature
     of the Holders of Securities of such series or of their
     representative by proxy and the principal amounts and
     serial number 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
     triplicate of all votes cast at the meeting. A record, at
     least in triplicate, 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 such record the original reports of the inspectors of
     votes on any vote by ballot taken thereat and affidavits
     by one or more persons having knowledge of the facts
     setting forth a copy of the notice of the meeting and
     showing that such 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
<PAGE 78>

     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.

              This instrument 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 instrument.

              IN WITNESS WHEREOF, the parties hereto have
     caused this Indenture to be duly executed, and their
     respective corporate seals to be hereunto affixed and
     attested, all as of the day and year first above written.

                       (REVERSE OF SECURITY)

             This Security is one of a duly authorized issue of
     debt securities of the Company (herein called the
     "Securities"), issued and to be issued in one or more series
     under an Indenture, dated as of March 1, 2001 (herein called
     the "Indenture", which term shall have the meaning assigned
     to it in such instrument), between the Company and Bank One,
     NA, as trustee (herein called the "Trustee", which term
     includes any successor trustee under the Indenture), and
     reference is hereby made to the Indenture and all indentures
     supplemental thereto for a statement of the respective
     rights, limitations of rights, duties and immunities
     thereunder of the Company, the Trustee and the Holders of
     the Securities and of the terms upon which the Securities
     are, and are to be, authenticated and delivered.  This
     Security is one of the series designated on the face hereof,
     limited in aggregate principal amount to $150,000,000.

             The Securities of this series are subject to
     redemption upon not less than 30 nor more than 60 days'
     notice by first-class mail, at any time, as a whole or in
     part, at the election of the Company, at a Redemption Price
     equal to the greater of (i) 100% of the principal amount of
     the Securities of this series to be redeemed or (ii) the sum
     of the present values of the remaining scheduled payments of
     principal and interest on the Securities of this series to
     be redeemed (not including any portion of such payments of
     interest accrued as of the Redemption Date) discounted to
     the Redemption Date on a semi-annual basis (assuming a
     360-day year consisting of twelve 30-day months) at the
     Treasury Rate plus 30 basis points, plus, in each case,
     accrued and unpaid interest on the principal amount of the
     Securities of this series being redeemed to the Redemption
     Date; provided that interest payments due on or prior to the
     Redemption Date will be paid to the record holders of such
     Securities on the relevant record date.  As used herein the
     following terms will have the definitions given below:

             "Treasury Rate" means, with respect to any
     Redemption Date, the rate per annum equal to the semiannual
     equivalent yield to maturity or interpolated (on a day count
     basis) of the Comparable Treasury Issue, assuming a price
     for the Comparable Treasury Issue (expressed as a percentage
     of its principal amount) equal to the Comparable Treasury
     Price for such Redemption Date.

             "Comparable Treasury Issue" means the United States
     Treasury security or securities selected by an Independent
     Investment Banker as having a maturity or interpolated (on a
     day count basis) comparable to the remaining term of the
     Securities of this series to be redeemed that would be
     utilized, at the time of selection and in accordance with
     customary financial practice, in pricing new issues of
     corporate debt securities of a comparable maturity to the
     remaining term of the Securities.

             "Independent Investment Banker" means one of the
     Reference Treasury Dealers appointed by the Trustee after
     consultation with the Company.

             "Comparable Treasury Price" means, with respect to
     any Redemption Date, (i) the average of the Reference
     Treasury Dealer Quotations for such Redemption Date, after
     excluding the highest and lowest such Reference Treasury
     Dealer Quotations, or (ii) if the Trustee obtains fewer than
     four such Reference Treasury Dealer Quotations, the average
     of all such quotations.

             "Reference Treasury Dealer Quotations" means, with
     respect to each Reference Treasury Dealer and any Redemption
     Date, the average, as determined by the Trustee, of the bid
     and asked prices for the Comparable Treasury Issue
     (expressed in each case as a percentage of its principal
     amount) quoted in writing to the Trustee by such Reference
     Treasury Dealer at 3:30 p.m. New York time on the third
     business day in The City of New York preceding such
     Redemption Date.

             "Reference Treasury Dealer" means at least five
     primary U.S. Government securities dealers in The City of
     New York as the Company shall select.

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

             There is no sinking fund or mandatory redemption
     obligation applicable to the Securities of this series.

             If a Change of Control occurs and is accompanied by
     a Rating Decline (together, a "Change of Control Triggering
     Event"), the Holder will have the right to require the
     Company to offer to repurchase all or any part (equal to
     $1,000 or an integral multiple thereof) of such Holder's
     Securities of this series at a purchase price in cash equal
     to the principal amount of such Securities plus accrued and
     unpaid interest, if any, to the date of purchase.  Within 30
     days following any Change of Control Triggering Event, the
     Company will mail the Change of Control Offer to each
     registered Holder with a copy to the Trustee.  No earlier
     than 30 days nor later than 60 days from the date such
     Change of Control Offer is mailed (the "Change of Control
     Payment Date"), the Company will, to the extent lawful, (i)
     accept for payment all Securities of this series or portions
     thereof (in integral multiples of $1,000) properly tendered
     and not withdrawn under the Change of Control Offer, (ii)
     deposit with the Paying Agent an amount equal to the Change
     of Control Payment in respect of all Securities of this
     series or portions thereof so tendered, and (iii) deliver or
     cause to be delivered to the Trustee the Securities of this
     series so accepted together with an Officers' Certificate
     stating the aggregate principal amount of such Securities or
     portions thereof being purchased by the Company.

             If an Event of Default with respect to Securities of
     this series shall occur and be continuing, the principal
     amount of the Securities of this series may be declared due
     and payable in the manner and with the effect and subject to
     the conditions provided in the Indenture.

             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 of each series to be
     affected under the Indenture at any time by the Company and
     the Trustee with the consent of the Holders of a majority in
     principal amount of the Securities at the time Outstanding
     of each series to be affected.  The Indenture also contains
     provisions permitting the Holders of a majority in principal
     amount of the Securities of each series at the time
     Outstanding, on behalf of the Holders of all Securities of
     such series, to waive compliance by the Company with certain
     provisions of the Indenture and 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 of any Security 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, if
     any) and interest on this Security at the times, place and
     rate, and in the coin or currency, herein prescribed.

             As provided in the Indenture and subject to certain
     limitations therein set forth, the transfer of this Security
     is registrable in the Security Register, 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, 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 his attorney duly authorized in writing, and
     thereupon one or more new Securities of this series and of
     like tenor, of authorized denominations and for the same
     aggregate principal amount, will be issued to the designated
     transferee or transferees.

             The Securities of this series are issuable only in
     registered form without coupons in denominations of $1,000
     and any integral multiple thereof.  As provided in the
     Indenture and subject to certain limitations therein set
     forth, Securities of this series are exchangeable for a like
     aggregate principal amount of Securities of this series and
     of like tenor of a different authorized denomination, as
     requested by the Holder surrendering the same.

             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 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.

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