Securities Custodian or under such Global Security, and the Depositary may be
treated by the Company, the Trustee and any agent of the Company or the Trustee
as the absolute owner of such Global Security for all purposes whatsoever.
Notwithstanding the foregoing, nothing herein shall prevent the Company, the
Trustee or any agent of the Company or the Trustee from giving effect to any
written certification, proxy or other authorization furnished by the Depositary
or impair, as between the Depositary and its Participants, the operation of
customary practices of such Depositary governing the exercise of the rights of a
holder of a beneficial interest in any Global Security.

         (d) Definitive Securities. Except as provided in Section 2.7, owners of
beneficial interests in Global Securities will not be entitled to receive

charge imposed upon or as a result of such payment by the United States or any
political subdivision or taxing authority thereof or therein, will not be less

withholding for or on account of any such tax, assessment or governmental
charge. The foregoing obligation to pay such Additional Amounts shall not apply
to:

         (a) any tax, assessment or other governmental charge which would not
have been so imposed but for:

                  (i) the existence of any present or former connection between
         such Holder (or a fiduciary, settlor, beneficiary, member or
         shareholder of, or holder of a power over, such Holder, if such Holder

         including, without limitation, such Holder (or such fiduciary, settlor,

         holding company or foreign personal holding company or controlled
         foreign corporation for United States federal income tax purposes or
         corporation which accumulates earnings to avoid United States federal
         income tax;

         (b) any tax, assessment or other governmental charge which would not
have been so imposed but for the presentation by the Holder of such Securities

became due and payable or the date on which payment thereof is duly provided
for, whichever occurs later;

         (c) any estate, inheritance, gift, sales, transfer, personal property

         (d) any tax, assessment or other governmental charge which is payable

interest, if any, on any of the Securities;

         (e) any tax, assessment or other governmental charge imposed on
interest received by a Holder or beneficial owner of the Securities who actually
or constructively owns 10% or more of the total combined voting power of all
classes of stock of the Company entitled to vote within the meaning of Section
871(h)(3) of the United States Internal Revenue Code of 1986, as amended;

         (f) any tax, assessment or other governmental charge imposed as a
result of the failure to comply with:

                  (i) certification, information, documentation, reporting or
         other similar requirements concerning the nationality, residence,
         identity or connection with the United States of the Holder or
         beneficial owner of the Securities, if such compliance is required by
         statute, or by regulation of the United States Treasury Department, as
         a precondition to relief or exemption from such tax, assessment or
         other governmental charge (including backup withholding), or



                                       7
<PAGE>   8

                  (ii) any other certification, information, documentation,
         reporting or other similar requirements under United States income tax
         laws or regulations that would establish entitlement to otherwise
         applicable relief or exemption from such tax, assessment or other
         governmental charge;

         (g) any tax, assessment or other governmental charge required to be
withheld by any Paying Agent from any payment of the principal of or interest,
if any, on any of the Securities, if such payment can be made without such
withholding by at least one other Paying Agent;

         (h) any tax, assessment or other governmental charge that is required
to be made pursuant to any European Union directive on the taxation of savings
income or any law implementing or complying with, or introduced to conform to,
any such directive; or

         (i) any combination of items (a), (b), (c), (d), (e), (f), (g) or (h);

nor will such Additional Amounts be paid to any Holder who is a fiduciary or
partnership or other than the sole beneficial owner of the Securities to the
extent a settlor or beneficiary with respect to such fiduciary or a member of
such partnership or a beneficial owner of the Securities would not have been
entitled to payment of such Additional Amounts had such beneficiary, settlor,
member or beneficial owner been the Holder of the Securities. The Securities are
subject in all cases to any tax, fiscal or other law or regulation or
administrative or judicial interpretation applicable thereto. Except as
specifically provided under this Section 2.4 and under Section 2.5, the Company
shall not be required to make any payment with respect to any tax, assessment or
governmental charge imposed by any government or a political subdivision or
taxing authority thereof or therein.

         SECTION 2.5 Redemption for Tax Reasons. If, as a result of:

                  (i) any change in or amendment to the laws (including any
         regulations or rulings promulgated thereunder) of the United States or
         any political subdivision thereof or therein affecting taxation, which
         becomes effective after the date of the Purchase Agreement or which
         proposal is made after such date,

                  (ii) any change in the official application or interpretation
         of such laws, including any official proposal for such a change,
         amendment or change in the application or interpretation of such laws,
         which change, amendment, application or interpretation is announced or
         becomes effective after the date of the Purchase Agreement or which
         proposal is made after such date,

                  (iii) any action taken by any taxing authority of the United
         States which action is taken or becomes generally known after the date
         of the Purchase Agreement, or any commencement of a proceeding in a
         court of competent jurisdiction in the United States after such date,
         whether or not such action was taken or such proceeding was brought
         with respect to the Company,

there is, in such case, in the written opinion of independent legal counsel of
recognized standing to the Company, a material increase in the probability that
the Company has or may become obligated to pay Additional Amounts, and the
Company in its business judgment, determines that



                                       8
<PAGE>   9

such obligation cannot be avoided by the use of reasonable measures available to
it, not including assignment of the Securities, the Securities of any Series
affected thereby may be redeemed, as a whole but not in part, at the Company's
option at any time thereafter, upon notice to the Trustee and the Holders of the
Securities affected thereby in accordance with the provisions of this
Supplemental Indenture at a redemption price equal to 100% of the principal
amount of the Securities to be redeemed together with accrued interest thereon

         SECTION 2.6 Transfer and Exchange.

         (a) Transfer and Exchange of Definitive Securities. When Definitive
Securities are presented to the Registrar with a request:

                  (i) to register the transfer of such Definitive Securities; or

                  (ii) to exchange such Definitive Securities for an equal
         principal amount of Definitive Securities of other authorized
         denominations, the Registrar shall register the transfer or make the
         exchange as requested if its reasonable requirements for such
         transaction are met; provided, however, that the Definitive Securities
         surrendered for transfer or exchange:

                           (A) shall be duly endorsed or accompanied by a
                  written instrument of transfer in form reasonably satisfactory
                  to the Company and the Registrar, duly executed by the Holder
                  thereof or his attorney duly authorized in writing; and

                           (B) are accompanied by the following additional
                  information and documents, as applicable:

                                    (x) if such Definitive Securities are being
                           delivered to the Registrar by a Holder for
                           registration in the name of such Holder, without
                           transfer, a certification from such Holder to that
                           effect (in the form set forth on the reverse side of
                           the Initial Security); or

                                    (y) if such Definitive Securities are being
                           transferred to the Company, a certification to that
                           effect (in the form set forth on the reverse side of
                           the Initial Security); or

                           (C) if such Definitive Securities are being
                  transferred pursuant to an exemption from registration in
                  accordance with Rule 144 under the Securities Act or in
                  reliance upon another exemption from the registration
                  requirements of the Securities Act, (i) a certification to
                  that effect (in the form set forth on the reverse side of the
                  Initial Security) and (ii) if the Company so requests, an
                  opinion of counsel or other evidence reasonably satisfactory
                  to it as to the compliance with the restrictions set forth in
                  the legend set forth in Section 2.6(e)(i).

         (b) Restrictions on Transfer of a Definitive Security for a Beneficial
Interest in a Global Security. A Definitive Security may not be exchanged for a
beneficial interest in a Global Security except upon satisfaction of the
requirements set forth below. Upon receipt by the



                                       9
<PAGE>   10

Trustee of a Definitive Security, duly endorsed or accompanied by a written
instrument of transfer in form reasonably satisfactory to the Company and the
Registrar, together with:

                  (i) certification (in the form set forth on the reverse side
         of the Initial Security) that such Definitive Security is being
         transferred (A) to a QIB in accordance with Rule 144A, (B) to an IAI
         that has furnished to the Trustee a signed letter substantially in the
         form of Exhibit B or (C) outside the United States in an offshore
         transaction within the meaning of Regulation S and in compliance with
         Rule 904 under the Securities Act; and

                  (ii) written instructions directing the Trustee to make, or to
         direct the Securities Custodian to make, an adjustment on its books and
         records with respect to such Global Security to reflect an increase in
         the aggregate principal amount of the Securities represented by the
         Global Security, such instructions to contain information regarding the
         Depositary account to be credited with such increase, then the Trustee
         shall cancel such Definitive Security and cause, or direct the
         Securities Custodian to cause, in accordance with the standing
         instructions and procedures existing between the Depositary and the
         Securities Custodian, the aggregate principal amount of Securities
         represented by the Global Security to be increased by the aggregate
         principal amount of the Definitive Security to be exchanged and shall
         credit or cause to be credited to the account of the Person specified
         in such instructions a beneficial interest in the Global Security equal
         to the principal amount of the Definitive Security so canceled. If no
         Global Securities are then outstanding and the Global Security has not
         been previously exchanged for certificated securities pursuant to
         Section 2.7, the Company shall issue and the Trustee shall
         authenticate, upon written order of the Company in the form of an
         Officers' Certificate, a new Global Security in the appropriate
         principal amount.

         (c) Transfer and Exchange of Global Securities.

                  (i) The transfer and exchange of Global Securities or
         beneficial interests therein shall be effected through the Depositary,
         in accordance with this Supplemental Indenture (including applicable
         restrictions on transfer set forth herein, if any) and the procedures
         of the Depositary therefor. A transferor of a beneficial interest in a
         Global Security shall deliver a written order given in accordance with
         the Depositary's procedures containing information regarding the
         participant account of the Depositary to be credited with a beneficial
         interest in such Global Security or another Global Security and such
         account shall be credited in accordance with such order with a
         beneficial interest in the applicable Global Security and the account
         of the Person making the transfer shall be debited by an amount equal
         to the beneficial interest in the Global Security being transferred.
         Transfers by an owner of a beneficial interest in a Rule 144A Global
         Security or an IAI Global Security to a transferee who takes delivery
         of such interest through a Regulation S Global Security, whether before
         or after the expiration of the Restricted Period, shall be made only
         upon receipt by the Trustee of a certification from the transferor to
         the effect that such transfer is being made in accordance with
         Regulation S or (if available) Rule 144 under the Securities Act and
         that, if such transfer is being made prior to the expiration of the
         Restricted Period, the interest transferred shall be held immediately
         thereafter through Euroclear or Clearstream. In the case of a



                                       10
<PAGE>   11

         transfer of a beneficial interest in either a Regulation S Global
         Security or a Rule 144A Global Security for an interest in an IAI
         Global Security, the transferee must furnish a signed letter
         substantially in the form of Exhibit B to the Trustee.

                  (ii) If the proposed transfer is a transfer of a beneficial
         interest in one Global Security to a beneficial interest in another
         Global Security, the Registrar shall reflect on its books and records
         the date and an increase in the principal amount of the Global Security
         to which such interest is being transferred in an amount equal to the
         principal amount of the interest to be so transferred, and the
         Registrar shall reflect on its books and records the date and a
         corresponding decrease in the principal amount of Global Security from
         which such interest is being transferred.

                  (iii) Notwithstanding any other provisions of this
         Supplemental Indenture (other than the provisions set forth in Section
         2.7), a Global Security may not be transferred as a whole except 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.

                  (iv) In the event that a Global Security is exchanged for
         Definitive Securities pursuant to Section 2.7 prior to the consummation
         of the Registered Exchange Offer or the effectiveness of the Shelf
         Registration Statement with respect to such Securities, such Securities
         may be exchanged only in accordance with such procedures as are
         substantially consistent with the provisions of this Section 2.6
         (including the certification requirements set forth on the reverse of
         the Initial Securities intended to ensure that such transfers comply
         with Rule 144A, Regulation S or such other applicable exemption from
         registration under the Securities Act, as the case may be) and such
         other procedures as may from time to time be adopted by the Company.

         (d) Restrictions on Transfer of Regulation S Global Security.

                  (i) Prior to the expiration of the Restricted Period,
         interests in a Regulation S Global Security may only be held through
         Euroclear or Clearstream. During the Restricted Period, beneficial
         ownership interests in a Regulation S Global Security may only be sold,
         pledged or transferred through Euroclear or Clearstream in accordance
         with the Applicable Procedures and only (A) to the Company, (B) so long
         as such security is eligible for resale pursuant to Rule 144A, to a
         person whom the selling holder reasonably believes is a QIB that
         purchases for its own account or for the account of a QIB to whom
         notice is given that the resale, pledge or transfer is being made in
         reliance on Rule 144A, (C) in an offshore transaction in accordance
         with Regulation S, (D) pursuant to an exemption from registration under
         the Securities Act provided by Rule 144 (if applicable) under the
         Securities Act, (E) to an IAI purchasing for its own account, or for
         the account of such an IAI, in a minimum principal amount of Securities
         of $250,000 or (F) pursuant to an effective registration statement
         under the Securities Act, in each case in accordance with any
         applicable securities laws of any state of the United States. Prior to
         the expiration of the Restricted Period, transfers by an owner of a
         beneficial interest in a Regulation S Global Security to a transferee
         who takes delivery of such interest through a



                                       11
<PAGE>   12

         Rule 144A Global Security or a IAI Global Security shall be made only
         in accordance with the Applicable Procedures and upon receipt by the
         Trustee of a written certification from the transferor of the
         beneficial interest in the form provided on the reverse of the Initial
         Security to the effect that such transfer is being made to (i) a person
         whom the transferor reasonably believes is a QIB within the meaning of
         Rule 144A in a transaction meeting the requirements of Rule 144A or
         (ii) an IAI purchasing for its own account, or for the account of such
         an IAI, in a minimum principal amount of the Securities of $250,000.
         Such written certification shall no longer be required after the
         expiration of the Restricted Period. In the case of a transfer of a
         beneficial interest in a Regulation S Global Security for an interest
         in a IAI Global Security, the transferee must furnish a signed letter
         substantially in the form of Exhibit B to the Trustee.

                  (ii) Upon the expiration of the Restricted Period, beneficial
         ownership interests in a Regulation S Global Security shall be
         transferable in accordance with applicable law and the other terms of
         the Indenture.

         (e) Legends for Securities

                  (i) Except as permitted by the following paragraphs (ii),
         (iii), (iv) or (vi), each Security certificate evidencing the Global
         Securities and the Definitive Securities (and all Securities issued in
         exchange therefor or in substitution thereof) shall bear a legend in
         substantially the following form (each defined term in the legend being
         defined as such for purposes of the legend only):

                  THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT
                  OF 1933, AS AMENDED (THE "SECURITIES ACT"), OR THE SECURITIES
                  LAWS OF ANY STATE OR OTHER JURISDICTION. NEITHER THIS SECURITY
                  NOR ANY INTEREST OR PARTICIPATION HEREIN MAY BE REOFFERED,
                  SOLD, ASSIGNED, TRANSFERRED, PLEDGED, ENCUMBERED OR OTHERWISE
                  DISPOSED OF IN THE ABSENCE OF SUCH REGISTRATION OR UNLESS SUCH
                  TRANSACTION IS EXEMPT FROM, OR NOT SUBJECT TO, SUCH
                  REGISTRATION.

                  THE HOLDER OF THIS SECURITY BY ITS ACCEPTANCE HEREOF AGREES TO
                  OFFER, SELL OR OTHERWISE TRANSFER SUCH SECURITY, PRIOR TO THE
                  DATE (THE "RESALE RESTRICTION TERMINATION DATE") WHICH IS TWO
                  YEARS AFTER THE LATER OF THE ORIGINAL ISSUE DATE HEREOF AND
                  THE LAST DATE ON WHICH EITHER THE COMPANY OR ANY AFFILIATE OF
                  THE COMPANY WAS THE OWNER OF THIS SECURITY (OR ANY PREDECESSOR
                  OF SUCH SECURITY), ONLY (A) TO THE COMPANY, (B) PURSUANT TO A

                  ELIGIBLE FOR RESALE PURSUANT TO RULE 144A, TO A PERSON IT
                  REASONABLY BELIEVES IS A "QUALIFIED INSTITUTIONAL BUYER" AS
                  DEFINED IN RULE 144A UNDER THE SECURITIES ACT THAT PURCHASES
                  FOR ITS OWN ACCOUNT OR FOR THE ACCOUNT OF A



                                       12

                  INVESTOR, IN EACH CASE IN A MINIMUM PRINCIPAL AMOUNT OF THE
                  SECURITIES OF $250,000, FOR INVESTMENT PURPOSES AND NOT WITH A
                  VIEW TO OR FOR OFFER OR SALE IN CONNECTION WITH ANY
                  DISTRIBUTION IN VIOLATION OF THE SECURITIES ACT, OR (F)
                  PURSUANT TO ANY OTHER AVAILABLE EXEMPTION FROM THE
                  REGISTRATION REQUIREMENTS OF THE SECURITIES ACT, SUBJECT TO
                  THE RIGHT OF THE COMPANY AND THE TRUSTEE PRIOR TO ANY SUCH
                  OFFER, SALE OR TRANSFER PURSUANT TO CLAUSES (D), (E) OR (F) TO
                  REQUIRE THE DELIVERY OF AN OPINION OF COUNSEL, CERTIFICATION
                  AND/OR OTHER INFORMATION SATISFACTORY TO EACH OF THEM. THIS
                  LEGEND WILL BE REMOVED UPON THE REQUEST OF THE HOLDER AFTER
                  THE RESALE RESTRICTION TERMINATION DATE.

         Each Security evidencing a Global Security offered and sold to QIBs
pursuant to Rule 144A shall bear a legend in substantially the following form

                  EACH PURCHASER OF THIS SECURITY IS HEREBY NOTIFIED THAT THE
                  SELLER OF THIS SECURITY MAY BE RELYING ON THE EXEMPTION FROM
                  THE PROVISIONS OF SECTION 5 OF THE SECURITIES ACT PROVIDED BY
                  RULE 144A THEREUNDER.

         Each Definitive Security shall bear the following additional legend:

                  IN CONNECTION WITH ANY TRANSFER, THE HOLDER WILL DELIVER TO
                  THE REGISTRAR AND TRANSFER AGENT SUCH CERTIFICATES AND OTHER
                  INFORMATION AS SUCH TRANSFER AGENT MAY REASONABLY REQUIRE TO
                  CONFIRM THAT THE TRANSFER COMPLIES WITH THE FOREGOING
                  RESTRICTIONS.

                  (ii) Upon any sale or transfer of a Transfer Restricted
         Security that is a Definitive Security, the Registrar shall permit the
         Holder thereof to exchange such Transfer Restricted Security for a
         Definitive Security that does not bear the legends set forth above and
         rescind any restriction on the transfer of such Transfer Restricted
         Security if the Holder certifies in writing to the Registrar that its
         request for such exchange was made in reliance on Rule 144 (such
         certification to be in the form set forth on the reverse of the Initial
         Security).

                  (iii) After a transfer of any Initial Securities or Private
         Exchange Securities during the period of the effectiveness of a Shelf
         Registration Statement with respect to such Initial Securities or
         Private Exchange Securities, as the case may be, all requirements
         pertaining to the Restricted Securities Legend on such Initial
         Securities or such Private Exchange Securities shall cease to apply and
         the requirements that any such Initial Securities or such Private
         Exchange Securities be issued in global form shall continue to apply.

                  (iv) Upon the consummation of a Registered Exchange Offer with
         respect to the Initial Securities pursuant to which Holders of such
         Initial Securities are offered Exchange Securities in exchange for
         their Initial Securities, all requirements pertaining to Initial
         Securities that Initial Securities be issued in global form shall
         continue to apply, and Exchange Securities in global form without the
         Restricted Securities Legend shall be available to Holders that
         exchange such Initial Securities in such Registered Exchange Offer.

                  (v) Upon the consummation of a Private Exchange with respect
         to the Initial Securities pursuant to which Holders of such Initial
         Securities are offered Private Exchange Securities in exchange for

         Securities that Initial Securities be issued in global form shall
         continue to apply, and Private Exchange Securities in global form with
         the Restricted Securities Legend shall be available to Holders that
         exchange such Initial Securities in such Private Exchange.

                  (vi) Upon a sale or transfer after the expiration of the
         Restricted Period of any Initial Security acquired pursuant to
         Regulation S, all requirements that such Initial Security bear the
         Restricted Securities Legend shall cease to apply and the requirements
         requiring any such Initial Security be issued in global form shall
         continue to apply.

         (f) Cancellation or Adjustment of Global Security. At such time as all
beneficial interests in a Global Security have either been exchanged for
Definitive Securities, transferred, redeemed, repurchased or canceled, such
Global Security shall be returned by the Depositary to the Trustee for
cancellation or retained and canceled by the Trustee. At any time prior to such
cancellation, if any beneficial interest in a Global Security is exchanged for
Definitive Securities, transferred in exchange for an interest in another Global
Security, redeemed, repurchased or canceled, the principal amount of Securities
represented by such Global Security shall be reduced and an adjustment shall be
made on the books and records of the Trustee (if it is then the Securities
Custodian for such Global Security) with respect to such Global Security, by the
Trustee or the Securities Custodian, to reflect such reduction.

         (g) Obligations with Respect to Transfers and Exchanges of Securities.

                  (i) To permit registrations of transfers and exchanges, the
         Company shall execute and the Trustee shall authenticate, Definitive
         Securities and Global Securities at the Registrar's request.

<PAGE>   15

                  (ii) No service charge shall be made for any registration of
         transfer or exchange, but the Company may require payment of a sum
         sufficient to cover any transfer tax, assessments, or similar
         governmental charge payable in connection therewith (other than any
         such transfer taxes, assessments or similar governmental charge payable
         upon exchange or transfer pursuant to Sections 8.5 or 12.3 of the
         Indenture).

                  (iii) Prior to the due presentation for registration of
         transfer of any Security, the Company, the Trustee, the Paying Agent or
         the Registrar may deem and treat the person in whose name a Security is
         registered as the absolute owner of such Security for the purpose of
         receiving payment of principal of and interest on such Security and for
         all other purposes whatsoever, whether or not such Security is overdue,
         and none of the Company, the Trustee, the Paying Agent or the Registrar
         shall be affected by notice to the contrary.

                  (iv) The Company shall not be required to make and the
         Registrar need not register transfers or exchanges of Securities
         selected for redemption (except, in the case of Securities to be
         redeemed in part, the portion thereof not to be redeemed) or any
         Securities for a period of 15 days before the mailing of a notice of
         redemption of Securities to be redeemed.

                  (v) All Securities issued upon any transfer or exchange
         pursuant to the terms of this Supplemental Indenture shall evidence the
         same Debt and shall be entitled to the same benefits under the
         Indenture as the Securities surrendered upon such transfer or exchange.

         (h) No Obligation of the Trustee.

                  (i) The Trustee shall have no responsibility or obligation to
         any beneficial owner of a Global Security, a member of, or a
         participant in the Depositary or any other Person with respect to the
         accuracy of the records of the Depositary or its nominee or of any
         participant or member thereof, with respect to any ownership interest
         in the Securities or with respect to the delivery to any participant,
         member, beneficial owner or other Person (other than the Depositary) of
         any notice (including any notice of redemption or repurchase) or the
         payment of any amount, under or with respect to such Securities. All
         notices and communications to be given to the Holders and all payments
         to be made to Holders under the Securities shall be given or made only
         to the registered Holders (which shall be the Depositary or its nominee
         in the case of a Global Security). The rights of beneficial owners in
         any Global Security shall be exercised only through the Depositary
         subject to the applicable rules and procedures of the Depositary. The
         Trustee may rely and shall be fully protected in relying upon
         information furnished by the Depositary with respect to its members,
         participants and any beneficial owners.

                  (ii) The Trustee shall have no obligation or duty to monitor,
         determine or inquire as to compliance with any restrictions on transfer
         imposed under this Supplemental Indenture or under applicable law with
         respect to any transfer of any interest in any Security (including any
         transfers between or among Depositary participants, members or
         beneficial owners in any Global Security) other than to require

         delivery of such certificates and other documentation or evidence as
         are expressly required by, and to do so if and when expressly required
         by, the terms of this Supplemental Indenture, and to examine the same
         to determine substantial compliance as to form with the express
         requirements hereof.

         SECTION 2.7 Definitive Securities.

         (a) A Global Security deposited with the Depositary or with the Trustee
as Securities Custodian pursuant to Section 2.3 shall be transferred to the
beneficial owners thereof in the form of Definitive Securities in an aggregate
principal amount equal to the principal amount of such Global Security, in
exchange for such Global Security, only if such transfer complies with Section
2.6 and (i) the Company notifies the Trustee that the Depositary, Euroclear or
Clearstream is no longer willing or able to act as a depositary or clearing
system for the Securities or the Depositary or the Depositary ceases to be a
"clearing agency" registered under the Exchange Act, and a successor depositary
or clearing system is not appointed by the Company within 90 days of such notice
or cessation, (ii) the Company, in its sole discretion, notifies the Trustee in
writing that it elects to cause the issuance of Definitive Securities under the
Indenture, or (iii) upon the occurrence and continuation of an Event of Default.

         (b) Any Global Security that is transferable to the beneficial owners
thereof pursuant to this Section 2.7 shall be surrendered by the Depositary to
the Trustee, to be so transferred, in whole or from time to time in part,
without charge, and the Trustee shall authenticate and deliver, upon such
transfer of each portion of such Global Security, an equal aggregate principal
amount of Definitive Securities of authorized denominations. Any portion of a
Global Security transferred pursuant to this Section 2.7 shall be executed,
authenticated and delivered only in denominations of $1,000 of principal amount
and any integral multiple thereof and registered in such names as the Depositary
shall direct. Any certificated Initial Security in the form of a Definitive
Security delivered in exchange for an interest in the Global Security shall,
except as otherwise provided by Section 2.6, bear the Restricted Securities
Legend.

         (c) The registered Holder of a Global Security may grant proxies and
otherwise authorize any Person, including Participants and Persons that may hold
interests through Participants, to take any action which a Holder is entitled to
take under the Indenture or the Securities.

         (d) In the event of the occurrence of any of the events specified in
Section 2.7(a)(i), (ii) or (iii), the Company will promptly make available to
the Trustee a reasonable supply of Definitive Securities in fully registered
form without interest coupons.

         SECTION 2.8 Notice to Securityholders. For the sole benefit of the
Holders of the Securities, Section 11.4 of the Indenture shall be amended by
adding a new clause (3) at the end of the first sentence of the second paragraph
as follows:

                  "and (3) for so long as a Series of Securities is listed on
                  the Luxembourg Stock Exchange and it is required by the rules
                  of the Luxembourg Stock Exchange, such notice shall be

this Supplemental Indenture, is in all respects hereby adopted, ratified and

         SECTION 3.2 Counterparts. This Supplemental Indenture may be executed
in any number of counterparts, each of which when so executed shall be deemed an
original, and all such counterparts shall together constitute but one and the
same instrument.

         Unless this certificate is presented by an authorized representative of
The Depository Trust Company, a New York corporation ("DTC"), to the Company (as
defined below) or its agent for registration of transfer, exchange or payment,
and any certificate issued is registered in the name of Cede & Co. or in such
other name as is requested by an authorized representative of DTC (and any
payment is made to Cede & Co. or to such other entity as is requested by an
authorized representative of DTC), ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR

                                                       Common Code No.: [______]

         Kellogg Company, a corporation duly organized and existing under the
laws of Delaware (herein called the "Company", which term includes any successor
Person under the Indenture hereinafter referred to), for value received, hereby
promises to pay to CEDE & CO., or registered assigns, the principal sum set
forth above or such other principal sum on the Schedule attached hereto (which
shall not exceed U.S.$[______]) on April 1, 2003, and to pay interest thereon
from March 29, 2001 or from the most recent interest payment date to which
interest has been paid or duly provided for, semiannually on April 1 and October
1 in each year, commencing October 1, 2001, at the rate of 5.50% per annum,
until the principal hereof is paid or made available for payment; provided,
however, in the event (each such event in clauses (i) through (iii) below, being
referred to as a "Registration Default") that: (i) in the event that the Company
is permitted under the law and currently prevailing interpretations of the
Commission's staff to effect the Registered Exchange Offer and (A) the Exchange
Offer Registration Statement is not filed with the Commission on or prior to the
90th day following the Issue Date, (B) the Exchange Offer Registration Statement
is not declared effective on or prior to the 180th day following the Issue Date,
or (C) the Registered Exchange Offer is not consummated on or prior to the 225th
day following the Issue Date; (ii) in the event the Company is required to file
a Shelf Registration Statement and the Shelf Registration Statement (A) is not
filed with the Commission on or prior to the date specified in Section 3, or (B)
is not declared effective by the Commission on or prior to the date specified in
Section 3; or (iii) after a Registration Statement is declared effective, (A)
such Registration Statement ceases to be effective prior to the end of the
Exchange Offer Registration Period or the Shelf Registration Period, as
applicable, or (B) such Registration Statement or the related Prospectus ceases
to be useable in connection with resales of the Securities covered by such
Registration Statement prior to the end of the Exchange Offer Registration
Period or the Shelf Registration Period, as applicable then, in the event of a
Registration Default under clause (i) or (ii) above, Additional Interest shall
accrue on the

                                       A-1
<PAGE>   20
Securities affected thereby over and above the interest rate set forth in the
title to the Securities from and including the next day following each such
Registration Default, in each case at a rate equal to 0.25% per annum and, in
the event of a Registration Default under clause (iii) above, if the aggregate
number of days in any consecutive 12-month period for which the Registration
Statement shall not be usable exceeds 60 days in the aggregate, then Additional
Interest shall accrue on the Securities affected thereby over and above the
interest rate set forth in the title to the Securities from and including the
next day following the 60th such day at a rate equal to 0.25% per annum;
provided, that the aggregate Additional Interest will in no event exceed 0.25%
per annum. Additional Interest attributable to a Registration Default shall
cease to accrue once such Registration Default is cured.

         The Company shall notify the Trustee within three Business Days after
the occurrence of a Registration Default, and Additional Interest shall be paid
by depositing with the Trustee, in trust for the benefit of the Holders entitled
to receive the Additional Interest, on or before the applicable semiannual
interest payment date, immediately available funds in sums sufficient to pay the
Additional Interest then due. The Additional Interest due shall be payable on
each interest payment date to the record Holder entitled to receive the interest
payment to be paid on such date as set forth in the Indenture. For so long as
the Securities are listed on the Luxembourg Stock Exchange, the Company shall
also publish a notice of the requirement to pay Additional Interest in an
Authorized Newspaper.

         The interest (and Additional Interest, if any) so payable, and
punctually paid or duly provided for, on any interest payment date will, as
provided in the Indenture, be paid to the Person in whose name this Security (or
one or more Predecessor Securities) is registered at the close of business on
the regular record date for such interest, which shall be the March 15 or
September 15 (whether or not a Business Day), as the case may be, next preceding
such interest payment date. Any such interest not so punctually paid or duly
provided for will forthwith cease to be payable to the Holder on such regular
record date and may either be paid to the Person in whose name this Security (or
one or more Predecessor Securities) is registered at the close of business on a
special record date for the payment of such Defaulted Interest to be fixed by
the Trustee, notice whereof shall be given to Holders of Securities of this
series not less than 10 days prior to such special record date, or be paid at
any time in any other lawful manner not inconsistent with the requirements of
any securities exchange on which the Securities of this series may be listed,
and upon such notice as may be required by such exchange, all as more fully
provided in the Indenture.

         Payment of the principal of (and premium, if any) and interest (and
Additional Interest, if any) on this Security will be made at the office or
agency of the Company maintained for that purpose in the Borough of Manhattan,
The City of New York, in such coin or currency of the United States of America
as at the time of payment is legal tender for payment of public and private
debts; provided, however, that at the option of the Company payment of interest
may be made by check mailed to the address of the Person entitled thereto as
such address shall appear in the Security Register or by wire transfer to an
account maintained by the Person entitled thereto as specified in the Security
Register, provided that such Person shall have given the Trustee written wire
instructions at least five Business Days prior to the applicable Interest
Payment Date.

         Reference is hereby made to the further provisions of this Security set

the Trustee referred to on the reverse hereof by manual signature, this Security
shall not be entitled to any benefit under the Indenture or be valid or
obligatory for any purpose.

                       [FORM OF REVERSE SIDE OF SECURITY]

                               5.50% Note due 2003



         Section 1. Indenture

         The Company issued the Securities under an Indenture, dated as of March
15, 2001, between the Company and the Trustee, and Supplemental Indenture No. 1
thereto, dated as of March 29, 2001 (collectively, the "Indenture"). The terms
of the Securities include those stated in the Indenture and those made part of
the Indenture by reference to the Trust Indenture Act as in effect on the date
of the Indenture. Terms defined in the Indenture and not defined herein have the
meanings ascribed thereto in the Indenture. The Securities are subject to all
terms and provisions of the Indenture, and Securityholders are referred to the
Indenture and the Trust Indenture Act for a statement of such terms and
provisions.

         The Securities are senior unsecured obligations of the Company
initially limited to $1,000,000,000 aggregate principal amount at any one time
outstanding. This Security is one of the Initial Securities referred to in the
Indenture. The Securities include the Initial Securities and any Exchange
Securities and Private Exchange Securities issued in exchange for Initial
Securities. The Initial Securities, the Exchange Securities and the Private
Exchange Securities are treated as a single class of securities under the
Indenture.

         Section 2. Redemption

         The Securities are not redeemable prior to April 1, 2003, except as
provided in Section 2.5 of Supplemental Indenture No. 1 to the Indenture.

         Section 3. Sinking Fund

         The Securities are not subject to any sinking fund.

         Section 4. Denominations; Transfer; Exchange

         The Securities are in registered form without coupons in denominations
of $1,000 and whole multiples of $1,000. A Holder may transfer or exchange
Securities in accordance with the Indenture. Upon any transfer or exchange, the
Registrar and the Trustee may require a Holder, among other things, to furnish
appropriate endorsements or transfer documents and to pay any taxes required by
law or permitted by the Indenture. The Registrar need not register the transfer
of or exchange any Securities selected for redemption or to transfer or exchange
any Securities for a period of 15 days prior to the mailing of a notice of
redemption of Securities to be redeemed.

         Section 5. Persons Deemed Owners

         The registered Holder of this Security may be treated as the owner of
it for all purposes.

                                       A-5
<PAGE>   24

         Section 6. Unclaimed Money

         If money for the payment of principal or interest remains unclaimed for
two years, the Trustee or Paying Agent shall pay the money back to the Company
at its written request unless an abandoned property law designates another
Person. After any such payment, Holders entitled to the money must look only to
the Company and not to the Trustee for payment.

         Section 7. Discharge and Defeasance

         Subject to certain conditions, the Company at any time may terminate
some of or all its obligations under the Securities and the Indenture if the
Company deposits with the Trustee money or U.S. Government Obligations for the
payment of principal and interest on the Securities to redemption or maturity,
as the case may be.

         Section 8. Trustee Dealings with the Company

         Subject to certain limitations imposed by the Trust Indenture Act, the
Trustee under the Indenture, in its individual or any other capacity, may become
the owner or pledgee of Securities and may otherwise deal with and collect
obligations owed to it by the Company or its Affiliates and may otherwise deal
with the Company or its Affiliates with the same rights it would have if it were
not Trustee.

         Section 9. No Recourse Against Others

         A director, officer, employee or stockholder, as such, of the Company
shall not have any liability for any obligations of the Company under the
Securities or the Indenture or for any claim based on, in respect of or by
reason of such obligations or their creation. By accepting a Security, each
Securityholder waives and releases all such liability. The waiver and release
are part of the consideration for the issue of the Securities.

         Section 10. Authentication

         This Security shall not be valid until an authorized signatory of the
Trustee (or an authenticating agent) manually signs the certificate of
authentication on the other side of this Security.

         Section 11. Governing Law

         THIS SECURITY SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH,
THE LAWS OF THE STATE OF NEW YORK BUT WITHOUT GIVING EFFECT TO APPLICABLE
PRINCIPLES OF CONFLICTS OF LAW TO THE EXTENT THAT THE APPLICATION OF THE LAWS OF
ANOTHER JURISDICTION WOULD BE REQUIRED THEREBY.

         Section 12. CUSIP Numbers

         Pursuant to a recommendation promulgated by the Committee on Uniform
Security Identification Procedures, the Company has caused CUSIP numbers to be
printed on the



                                       A-6
<PAGE>   25

Securities and has directed the Trustee to use CUSIP numbers in notices of
redemption as a convenience to Securityholders. No representation is made as to
the accuracy of such numbers either as printed on the Securities or as contained
in any notice of redemption and reliance may be placed only on the other
identification numbers placed thereon.

         Section 13. Holders' Compliance with Registration Agreement

         Each Holder of a Security, by acceptance hereof, acknowledges and
agrees to the provisions of the Registration Agreement, including, without
limitation, the obligations of the Holders with respect to a registration and
the indemnification of the Company to the extent provided therein. In the event
of a conflict between the terms of this Security and the Registration Agreement,
the terms of the Registration Agreement shall control.

        The Company will furnish to any Holder of Securities upon written
             request and without charge to the Holder a copy of the
              Indenture which has in it the text of this Security.

and any certificate issued is registered in the name of Cede & Co. or in such
other name as is requested by an authorized representative of DTC (and any
payment is made to Cede & Co. or to such other entity as is requested by an

                                                       Common Code No.: [______]

         Kellogg Company, a corporation duly organized and existing under the
laws of Delaware (herein called the "Company", which term includes any successor
Person under the Indenture hereinafter referred to), for value received, hereby
promises to pay to CEDE & CO., or registered assigns, the principal sum set
forth above or such other principal sum on the Schedule attached hereto (which
shall not exceed U.S.$[______]) on April 1, 2006, and to pay interest thereon
from March 29, 2001 or from the most recent interest payment date to which
interest has been paid or duly provided for, semiannually on April 1 and October
1 in each year, commencing October 1, 2001, at the rate of 6.00% per annum,
until the principal hereof is paid or made available for payment; provided,
however, in the event (each such event in clauses (i) through (iii) below, being
referred to as a "Registration Default") that: (i) in the event that the Company
is permitted under the law and currently prevailing interpretations of the
Commission's staff to effect the Registered Exchange Offer and (A) the Exchange
Offer Registration Statement is not filed with the Commission on or prior to the
90th day following the Issue Date, (B) the Exchange Offer Registration Statement
is not declared effective on or prior to the 180th day following the Issue Date,
or (C) the Registered Exchange Offer is not consummated on or prior to the 225th
day following the Issue Date; (ii) in the event the Company is required to file
a Shelf Registration Statement and the Shelf Registration Statement (A) is not
filed with the Commission on or prior to the date specified in Section 3, or (B)
is not declared effective by the Commission on or prior to the date specified in
Section 3; or (iii) after a Registration Statement is declared effective, (A)
such Registration Statement ceases to be effective prior to the end of the
Exchange Offer Registration Period or the Shelf Registration Period, as
applicable, or (B) such Registration Statement or the related Prospectus ceases
to be useable in connection with resales of the Securities covered by such
Registration Statement prior to the end of the Exchange Offer Registration
Period or the Shelf Registration Period, as applicable then, in the event of a
Registration Default under clause (i) or (ii) above, Additional Interest shall
accrue on the



                                       A-12
<PAGE>   31

Securities affected thereby over and above the interest rate set forth in the
title to the Securities from and including the next day following each such
Registration Default, in each case at a rate equal to 0.25% per annum and, in
the event of a Registration Default under clause (iii) above, if the aggregate
number of days in any consecutive 12-month period for which the Registration
Statement shall not be usable exceeds 60 days in the aggregate, then Additional
Interest shall accrue on the Securities affected thereby over and above the
interest rate set forth in the title to the Securities from and including the
next day following the 60th such day at a rate equal to 0.25% per annum;
provided, that the aggregate Additional Interest will in no event exceed 0.25%
per annum. Additional Interest attributable to a Registration Default shall
cease to accrue once such Registration Default is cured.

         The Company shall notify the Trustee within three Business Days after
the occurrence of a Registration Default, and Additional Interest shall be paid
by depositing with the Trustee, in trust for the benefit of the Holders entitled
to receive the Additional Interest, on or before the applicable semiannual
interest payment date, immediately available funds in sums sufficient to pay the
Additional Interest then due. The Additional Interest due shall be payable on
each interest payment date to the record Holder entitled to receive the interest
payment to be paid on such date as set forth in the Indenture. For so long as
the Securities are listed on the Luxembourg Stock Exchange, the Company shall
also publish a notice of the requirement to pay Additional Interest in an
Authorized Newspaper.

         The interest (and Additional Interest, if any) so payable, and
punctually paid or duly provided for, on any interest payment date will, as
provided in the Indenture, be paid to the Person in whose name this Security (or
one or more Predecessor Securities) is registered at the close of business on
the regular record date for such interest, which shall be the March 15 or
September 15 (whether or not a Business Day), as the case may be, next preceding
such interest payment date. Any such interest not so punctually paid or duly
provided for will forthwith cease to be payable to the Holder on such regular
record date and may either be paid to the Person in whose name this Security (or
one or more Predecessor Securities) is registered at the close of business on a
special record date for the payment of such Defaulted Interest to be fixed by
the Trustee, notice whereof shall be given to Holders of Securities of this
series not less than 10 days prior to such special record date, or be paid at
any time in any other lawful manner not inconsistent with the requirements of
any securities exchange on which the Securities of this series may be listed,
and upon such notice as may be required by such exchange, all as more fully
provided in the Indenture.

         Payment of the principal of (and premium, if any) and interest (and
Additional Interest, if any) on this Security will be made at the office or
agency of the Company maintained for that purpose in the Borough of Manhattan,
The City of New York, in such coin or currency of the United States of America
as at the time of payment is legal tender for payment of public and private
debts; provided, however, that at the option of the Company payment of interest
may be made by check mailed to the address of the Person entitled thereto as
such address shall appear in the Security Register or by wire transfer to an
account maintained by the Person entitled thereto as specified in the Security
Register, provided that such Person shall have given the Trustee written wire
instructions at least five Business Days prior to the applicable Interest
Payment Date.

                       [FORM OF REVERSE SIDE OF SECURITY]

                               6.00% Note due 2006

         Section 1. Indenture

         The Company issued the Securities under an Indenture, dated as of March
15, 2001, between the Company and the Trustee, and Supplemental Indenture No. 1
thereto, dated as of March 29, 2001 (collectively, the "Indenture"). The terms
of the Securities include those stated in the Indenture and those made part of
the Indenture by reference to the Trust Indenture Act as in effect on the date
of the Indenture. Terms defined in the Indenture and not defined herein have the
meanings ascribed thereto in the Indenture. The Securities are subject to all
terms and provisions of the Indenture, and Securityholders are referred to the
Indenture and the Trust Indenture Act for a statement of such terms and
provisions.

         The Securities are senior unsecured obligations of the Company
initially limited to $1,000,000,000 aggregate principal amount at any one time
outstanding. This Security is one of the Initial Securities referred to in the
Indenture. The Securities include the Initial Securities and any Exchange
Securities and Private Exchange Securities issued in exchange for Initial
Securities. The Initial Securities, the Exchange Securities and the Private
Exchange Securities are treated as a single class of securities under the
Indenture.

         Section 2. Optional Redemption

         The Securities may be redeemed at the option of the Company, in whole
or in part, at any time or from time to time. The redemption price for the
Securities to be redeemed on any redemption date will be equal to the greater
of: (i)100% of the principal amount of the Securities being redeemed on the
redemption date; or (ii) the sum of the present values of the remaining
scheduled payments of principal and interest on the Securities being redeemed on
that redemption date (not including any portion of any payments of interest
accrued to the redemption date) discounted to the redemption date on a
semiannual basis at the Treasury Rate, plus 25 basis points, as determined by
the Reference Treasury Dealer, plus accrued and unpaid interest thereon to the
redemption date. Notwithstanding the foregoing, installments of interest on
Securities that are due and payable on interest payment dates falling on or
prior to a redemption date will be payable on the interest payment date to the
registered Holders as of the close of business on the relevant record date
according to the Securities and the Indenture. The redemption price will be
calculated on the basis of a 360-day year consisting of twelve 30-day months.

         The Company shall mail notice of any redemption at least 30 days but
not more than 60 days before the redemption date to each registered Holder of
the Securities to be redeemed. Once notice of redemption is mailed, the
Securities called for redemption will become due and payable on the redemption
date and at the applicable redemption price, plus accrued and unpaid interest to
the redemption date.

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



                                       A-16
<PAGE>   35

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

         "Comparable Treasury Price" means, with respect to any redemption date,
(A) the average of the Reference Treasury Dealer Quotations for such redemption
date, after excluding the highest and lowest such Reference Treasury Dealer
Quotations, or (B) if the trustee obtains fewer than three such Reference
Treasury Dealer Quotations, the average of all such Quotations, or (C) if only
one Reference Treasury Dealer Quotation is received, such Quotation.

         "Reference Treasury Dealer" means (A) Salomon Smith Barney Inc., Chase
Securities Inc. or Banc of America Securities LLC (or their respective
affiliates which are Primary Treasury Dealers), and their respective successors;
provided, however, that if any of the foregoing shall cease to be a primary U.S.
Government securities dealer in New York City (a "Primary Treasury Dealer"), we
will substitute therefor another Primary Treasury Dealer; and (B) any other
Primary Treasury Dealer(s) selected by us.

         "Reference Treasury Dealer Quotation" 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 5:00 p.m. (New York
City time) on the third business day preceding such redemption date.

         Section 3. Sinking Fund

         The Securities are not subject to any sinking fund.

         Section 4. Notice of Redemption

         Notice of redemption will be mailed by first-class mail at least 30
days but not more than 60 days before the redemption date to each Holder of
Securities to be redeemed at his or her registered address. Securities in
denominations larger than $1,000 of principal amount may be redeemed in part but
only in whole multiples of $1,000 of principal amount. If money sufficient to
pay the redemption price of and accrued and unpaid interest and liquidated
damages, if any, on all Securities (or portions thereof) to be redeemed on the
redemption date is deposited with the Paying Agent on or before the redemption
date and certain other conditions are satisfied, on and after such date interest
ceases to accrue on such Securities (or such portions thereof) called for
redemption.

         Section 5. Denominations; Transfer; Exchange

         The Securities are in registered form without coupons in denominations
of $1,000 and whole multiples of $1,000. A Holder may transfer or exchange
Securities in accordance with the Indenture. Upon any transfer or exchange, the
Registrar and the Trustee may require a Holder, among other things, to furnish
appropriate endorsements or transfer documents and to pay any taxes required by
law or permitted by the Indenture. The Registrar need not register the transfer




                                       A-17
<PAGE>   36

of or exchange any Securities selected for redemption (except, in the case of a
Security to be redeemed in part, the portion of the Security not to be redeemed)
or to transfer or exchange any Securities for a period of 15 days prior to the
mailing of a notice of redemption of Securities to be redeemed.

         Section 6. Persons Deemed Owners

         The registered Holder of this Security may be treated as the owner of
it for all purposes.

         Section 7. Unclaimed Money

         If money for the payment of principal or interest remains unclaimed for
two years, the Trustee or Paying Agent shall pay the money back to the Company
at its written request unless an abandoned property law designates another
Person. After any such payment, Holders entitled to the money must look only to
the Company and not to the Trustee for payment.

         Section 8. Discharge and Defeasance

         Subject to certain conditions, the Company at any time may terminate
some of or all its obligations under the Securities and the Indenture if the
Company deposits with the Trustee money or U.S. Government Obligations for the
payment of principal and interest on the Securities to redemption or maturity,
as the case may be.

         Section 9. Trustee Dealings with the Company

         Subject to certain limitations imposed by the Trust Indenture Act, the
Trustee under the Indenture, in its individual or any other capacity, may become
the owner or pledgee of Securities and may otherwise deal with and collect
obligations owed to it by the Company or its Affiliates and may otherwise deal
with the Company or its Affiliates with the same rights it would have if it were
not Trustee.

         Section 10. No Recourse Against Others

         A director, officer, employee or stockholder, as such, of the Company
shall not have any liability for any obligations of the Company under the
Securities or the Indenture or for any claim based on, in respect of or by
reason of such obligations or their creation. By accepting a Security, each
Securityholder waives and releases all such liability. The waiver and release
are part of the consideration for the issue of the Securities.

         Section 11. Authentication

         This Security shall not be valid until an authorized signatory of the
Trustee (or an authenticating agent) manually signs the certificate of
authentication on the other side of this Security.



                                       A-18
<PAGE>   37

         Section 12. Governing Law

         THIS SECURITY SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH,
THE LAWS OF THE STATE OF NEW YORK BUT WITHOUT GIVING EFFECT TO APPLICABLE
PRINCIPLES OF CONFLICTS OF LAW TO THE EXTENT THAT THE APPLICATION OF THE LAWS OF
ANOTHER JURISDICTION WOULD BE REQUIRED THEREBY.

         Section 13. CUSIP Numbers

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

         Section 14. Holders' Compliance with Registration Agreement

         Each Holder of a Security, by acceptance hereof, acknowledges and
agrees to the provisions of the Registration Agreement, including, without
limitation, the obligations of the Holders with respect to a registration and
the indemnification of the Company to the extent provided therein. In the event
of a conflict between the terms of this Security and the Registration Agreement,
the terms of the Registration Agreement shall control.

         The Company will furnish to any Holder of Securities upon written
request and without charge to the Holder a copy of the Indenture which has in it
the text of this Security.

The Depository Trust Company, a New York corporation ("DTC"), to the Company (as
defined below) or its agent for registration of transfer, exchange or payment,
and any certificate issued is registered in the name of Cede & Co. or in such
other name as is requested by an authorized representative of DTC (and any
payment is made to Cede & Co. or to such other entity as is requested by an
authorized representative of DTC), ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR
VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL inasmuch as the registered
owner hereof, Cede & Co., has an interest herein.

         No. [____]                                             U.S.$[_________]

                                                       Common Code No.: [______]


         Kellogg Company, a corporation duly organized and existing under the
laws of Delaware (herein called the "Company", which term includes any successor
Person under the Indenture hereinafter referred to), for value received, hereby
promises to pay to CEDE & CO., or registered assigns, the principal sum set
forth above or such other principal sum on the Schedule attached hereto (which
shall not exceed U.S.$[______]) on April 1, 2011, and to pay interest thereon
from March 29, 2001 or from the most recent interest payment date to which
interest has been paid or duly provided for, semiannually on April 1 and October
1 in each year, commencing October 1, 2001, at the rate of 6.60% per annum,
until the principal hereof is paid or made available for payment; provided,
however, in the event (each such event in clauses (i) through (iii) below, being
referred to as a "Registration Default") that: (i) in the event that the Company
is permitted under the law and currently prevailing interpretations of the
Commission's staff to effect the Registered Exchange Offer and (A) the Exchange
Offer Registration Statement is not filed with the Commission on or prior to the
90th day following the Issue Date, (B) the Exchange Offer Registration Statement
is not declared effective on or prior to the 180th day following the Issue Date,
or (C) the Registered Exchange Offer is not consummated on or prior to the 225th
day following the Issue Date; (ii) in the event the Company is required to file
a Shelf Registration Statement and the Shelf Registration Statement (A) is not
filed with the Commission on or prior to the date specified in Section 3, or (B)
is not declared effective by the Commission on or prior to the date specified in
Section 3; or (iii) after a Registration Statement is declared effective, (A)
such Registration Statement ceases to be effective prior to the end of the
Exchange Offer Registration Period or the Shelf Registration Period, as
applicable, or (B) such Registration Statement or the related Prospectus ceases
to be useable in connection with resales of the Securities covered by such
Registration Statement prior to the end of the Exchange Offer Registration
Period or the Shelf Registration Period, as applicable then, in the event of a




                                       A-24
<PAGE>   43

Registration Default under clause (i) or (ii) above, Additional Interest shall
accrue on the Securities affected thereby over and above the interest rate set
forth in the title to the Securities from and including the next day following
each such Registration Default, in each case at a rate equal to 0.25% per annum
and, in the event of a Registration Default under clause (iii) above, if the
aggregate number of days in any consecutive 12-month period for which the
Registration Statement shall not be usable exceeds 60 days in the aggregate,
then Additional Interest shall accrue on the Securities affected thereby over
and above the interest rate set forth in the title to the Securities from and
including the next day following the 60th such day at a rate equal to 0.25% per
annum; provided, that the aggregate Additional Interest will in no event exceed
0.25% per annum. Additional Interest attributable to a Registration Default
shall cease to accrue once such Registration Default is cured.

         The Company shall notify the Trustee within three Business Days after
the occurrence of a Registration Default, and Additional Interest shall be paid
by depositing with the Trustee, in trust for the benefit of the Holders entitled
to receive the Additional Interest, on or before the applicable semiannual
interest payment date, immediately available funds in sums sufficient to pay the
Additional Interest then due. The Additional Interest due shall be payable on
each interest payment date to the record Holder entitled to receive the interest
payment to be paid on such date as set forth in the Indenture. For so long as
the Securities are listed on the Luxembourg Stock Exchange, the Company shall
also publish a notice of the requirement to pay Additional Interest in an
Authorized Newspaper.

         The interest (and Additional Interest, if any) so payable, and
punctually paid or duly provided for, on any interest payment date will, as
provided in the Indenture, be paid to the Person in whose name this Security (or
one or more Predecessor Securities) is registered at the close of business on
the regular record date for such interest, which shall be the March 15 or
September 15 (whether or not a Business Day), as the case may be, next preceding
such interest payment date. Any such interest not so punctually paid or duly
provided for will forthwith cease to be payable to the Holder on such regular
record date and may either be paid to the Person in whose name this Security (or
one or more Predecessor Securities) is registered at the close of business on a
special record date for the payment of such Defaulted Interest to be fixed by
the Trustee, notice whereof shall be given to Holders of Securities of this
series not less than 10 days prior to such special record date, or be paid at
any time in any other lawful manner not inconsistent with the requirements of
any securities exchange on which the Securities of this series may be listed,
and upon such notice as may be required by such exchange, all as more fully
provided in the Indenture.

         Payment of the principal of (and premium, if any) and interest (and
Additional Interest, if any) on this Security will be made at the office or
agency of the Company maintained for that purpose in the Borough of Manhattan,
The City of New York, in such coin or currency of the United States of America
as at the time of payment is legal tender for payment of public and private
debts; provided, however, that at the option of the Company payment of interest
may be made by check mailed to the address of the Person entitled thereto as
such address shall appear in the Security Register or by wire transfer to an
account maintained by the Person entitled thereto as specified in the Security
Register, provided that such Person shall have given the Trustee written wire
instructions at least five Business Days prior to the applicable Interest
Payment Date.

                       [FORM OF REVERSE SIDE OF SECURITY]

                               6.60% Note due 2011

         Section 1. Indenture

          The Company issued the Securities under an Indenture, dated as of
March 15, 2001, between the Company and the Trustee, and Supplemental Indenture
No. 1 thereto, dated as of March 29, 2001 (collectively, the "Indenture"). The
terms of the Securities include those stated in the Indenture and those made
part of the Indenture by reference to the Trust Indenture Act as in effect on
the date of the Indenture. Terms defined in the Indenture and not defined herein
have the meanings ascribed thereto in the Indenture. The Securities are subject
to all terms and provisions of the Indenture, and Securityholders are referred
to the Indenture and the Trust Indenture Act for a statement of such terms and
provisions.

         The Securities are senior unsecured obligations of the Company
initially limited to $1,500,000,000 aggregate principal amount at any one time
outstanding. This Security is one of the Initial Securities referred to in the
Indenture. The Securities include the Initial Securities and any Exchange
Securities and Private Exchange Securities issued in exchange for Initial
Securities. The Initial Securities, the Exchange Securities and the Private
Exchange Securities are treated as a single class of securities under the
Indenture.

         Section 2. Optional Redemption

         The Securities may be redeemed at the option of the Company, in whole
or in part, at any time or from time to time. The redemption price for the
Securities to be redeemed on any redemption date will be equal to the greater
of: (i)100% of the principal amount of the Securities being redeemed on the
redemption date; or (ii) the sum of the present values of the remaining
scheduled payments of principal and interest on the Securities being redeemed on
that redemption date (not including any portion of any payments of interest
accrued to the redemption date) discounted to the redemption date on a
semiannual basis at the Treasury Rate, plus 30 basis points, as determined by
the Reference Treasury Dealer, plus accrued and unpaid interest thereon to the
redemption date. Notwithstanding the foregoing, installments of interest on
Securities that are due and payable on interest payment dates falling on or
prior to a redemption date will be payable on the interest payment date to the
registered Holders as of the close of business on the relevant record date
according to the Securities and the Indenture. The redemption price will be
calculated on the basis of a 360-day year consisting of twelve 30-day months.

         The Company shall mail notice of any redemption at least 30 days but
not more than 60 days before the redemption date to each registered Holder of
the Securities to be redeemed. Once notice of redemption is mailed, the
Securities called for redemption will become due and payable on the redemption
date and at the applicable redemption price, plus accrued and unpaid interest to
the redemption date.

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


                                       A-28
<PAGE>   47

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

         "Comparable Treasury Price" means, with respect to any redemption date,
(A) the average of the Reference Treasury Dealer Quotations for such redemption
date, after excluding the highest and lowest such Reference Treasury Dealer
Quotations, or (B) if the trustee obtains fewer than three such Reference
Treasury Dealer Quotations, the average of all such Quotations, or (C) if only
one Reference Treasury Dealer Quotation is received, such Quotation.

         "Reference Treasury Dealer" means (A) Salomon Smith Barney Inc., Chase
Securities Inc. or Banc of America Securities LLC (or their respective
affiliates which are Primary Treasury Dealers), and their respective successors;
provided, however, that if any of the foregoing shall cease to be a primary U.S.
Government securities dealer in New York City (a "Primary Treasury Dealer"), we
will substitute therefor another Primary Treasury Dealer; and (B) any other
Primary Treasury Dealer(s) selected by us.

         "Reference Treasury Dealer Quotation" 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 5:00 p.m. (New York
City time) on the third business day preceding such redemption date.

         Section 3. Sinking Fund

         The Securities are not subject to any sinking fund.

         Section 4. Notice of Redemption

         Notice of redemption will be mailed by first-class mail at least 30
days but not more than 60 days before the redemption date to each Holder of
Securities to be redeemed at his or her registered address. Securities in
denominations larger than $1,000 of principal amount may be redeemed in part but
only in whole multiples of $1,000 of principal amount. If money sufficient to
pay the redemption price of and accrued and unpaid interest and liquidated
damages, if any, on all Securities (or portions thereof) to be redeemed on the
redemption date is deposited with the Paying Agent on or before the redemption
date and certain other conditions are satisfied, on and after such date interest
ceases to accrue on such Securities (or such portions thereof) called for
redemption.

         Section 5. Denominations; Transfer; Exchange

         The Securities are in registered form without coupons in denominations
of $1,000 and whole multiples of $1,000. A Holder may transfer or exchange
Securities in accordance with the Indenture. Upon any transfer or exchange, the
Registrar and the Trustee may require a Holder, among other things, to furnish
appropriate endorsements or transfer documents and to pay any taxes required by
law or permitted by the Indenture. The Registrar need not register the transfer



                                       A-29
<PAGE>   48

of or exchange any Securities selected for redemption (except, in the case of a
Security to be redeemed in part, the portion of the Security not to be redeemed)
or to transfer or exchange any Securities for a period of 15 days prior to the
mailing of a notice of redemption of Securities to be redeemed.

         Section 6. Persons Deemed Owners

         The registered Holder of this Security may be treated as the owner of
it for all purposes.

         Section 7. Unclaimed Money

         If money for the payment of principal or interest remains unclaimed for
two years, the Trustee or Paying Agent shall pay the money back to the Company
at its written request unless an abandoned property law designates another
Person. After any such payment, Holders entitled to the money must look only to
the Company and not to the Trustee for payment.

         Section 8. Discharge and Defeasance

         Subject to certain conditions, the Company at any time may terminate
some of or all its obligations under the Securities and the Indenture if the
Company deposits with the Trustee money or U.S. Government Obligations for the
payment of principal and interest on the Securities to redemption or maturity,
as the case may be.

         Section 9. Trustee Dealings with the Company

         Subject to certain limitations imposed by the Trust Indenture Act, the
Trustee under the Indenture, in its individual or any other capacity, may become
the owner or pledgee of Securities and may otherwise deal with and collect
obligations owed to it by the Company or its Affiliates and may otherwise deal
with the Company or its Affiliates with the same rights it would have if it were
not Trustee.

         Section 10. No Recourse Against Others

         A director, officer, employee or stockholder, as such, of the Company
shall not have any liability for any obligations of the Company under the
Securities or the Indenture or for any claim based on, in respect of or by
reason of such obligations or their creation. By accepting a Security, each
Securityholder waives and releases all such liability. The waiver and release
are part of the consideration for the issue of the Securities.

         Section 11. Authentication

         This Security shall not be valid until an authorized signatory of the
Trustee (or an authenticating agent) manually signs the certificate of
authentication on the other side of this Security.

<PAGE>   49

         Section 12. Governing Law

         THIS SECURITY SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH,
THE LAWS OF THE STATE OF NEW YORK BUT WITHOUT GIVING EFFECT TO APPLICABLE
PRINCIPLES OF CONFLICTS OF LAW TO THE EXTENT THAT THE APPLICATION OF THE LAWS OF
ANOTHER JURISDICTION WOULD BE REQUIRED THEREBY.

         Section 13. CUSIP Numbers

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

         Section 14. Holders' Compliance with Registration Agreement

         Each Holder of a Security, by acceptance hereof, acknowledges and
agrees to the provisions of the Registration Agreement, including, without
limitation, the obligations of the Holders with respect to a registration and
the indemnification of the Company to the extent provided therein. In the event
of a conflict between the terms of this Security and the Registration Agreement,
the terms of the Registration Agreement shall control.

         The Company will furnish to any Holder of Securities upon written

The Depository Trust Company, a New York corporation ("DTC"), to the Company (as
defined below) or its agent for registration of transfer, exchange or payment,
and any certificate issued is registered in the name of Cede & Co. or in such
other name as is requested by an authorized representative of DTC (and any
payment is made to Cede & Co. or to such other entity as is requested by an

         Kellogg Company, a corporation duly organized and existing under the
laws of Delaware (herein called the "Company", which term includes any successor
Person under the Indenture hereinafter referred to), for value received, hereby
promises to pay to CEDE & CO., or registered assigns, the principal sum set
forth above or such other principal sum on the Schedule attached hereto (which
shall not exceed U.S.$[______]) on April 1, 2031, and to pay interest thereon
from March 29, 2001 or from the most recent interest payment date to which
interest has been paid or duly provided for, semiannually on April 1 and October
1 in each year, commencing October 1, 2001, at the rate of 7.45% per annum,
until the principal hereof is paid or made available for payment; provided,
however, in the event (each such event in clauses (i) through (iii) below, being
referred to as a "Registration Default") that: (i) in the event that the Company
is permitted under the law and currently prevailing interpretations of the
Commission's staff to effect the Registered Exchange Offer and (A) the Exchange
Offer Registration Statement is not filed with the Commission on or prior to the
90th day following the Issue Date, (B) the Exchange Offer Registration Statement
is not declared effective on or prior to the 180th day following the Issue Date,
or (C) the Registered Exchange Offer is not consummated on or prior to the 225th
day following the Issue Date; (ii) in the event the Company is required to file
a Shelf Registration Statement and the Shelf Registration Statement (A) is not
filed with the Commission on or prior to the date specified in Section 3, or (B)
is not declared effective by the Commission on or prior to the date specified in
Section 3; or (iii) after a Registration Statement is declared effective, (A)
such Registration Statement ceases to be effective prior to the end of the
Exchange Offer Registration Period or the Shelf Registration Period, as
applicable, or (B) such Registration Statement or the related Prospectus ceases
to be useable in connection with resales of the Securities covered by such
Registration Statement prior to the end of the Exchange Offer Registration
Period or the Shelf Registration Period, as applicable then, in the event of a



                                      A2-1
<PAGE>   55

Registration Default under clause (i) or (ii) above, Additional Interest shall
accrue on the Securities affected thereby over and above the interest rate set
forth in the title to the Securities from and including the next day following
each such Registration Default, in each case at a rate equal to 0.25% per annum
and, in the event of a Registration Default under clause (iii) above, if the
aggregate number of days in any consecutive 12-month period for which the
Registration Statement shall not be usable exceeds 60 days in the aggregate,
then Additional Interest shall accrue on the Securities affected thereby over
and above the interest rate set forth in the title to the Securities from and
including the next day following the 60th such day at a rate equal to 0.25% per
annum; provided, that the aggregate Additional Interest will in no event exceed
0.25% per annum. Additional Interest attributable to a Registration Default
shall cease to accrue once such Registration Default is cured.

         The Company shall notify the Trustee within three Business Days after
the occurrence of a Registration Default, and Additional Interest shall be paid
by depositing with the Trustee, in trust for the benefit of the Holders entitled
to receive the Additional Interest, on or before the applicable semiannual
interest payment date, immediately available funds in sums sufficient to pay the
Additional Interest then due. The Additional Interest due shall be payable on
each interest payment date to the record Holder entitled to receive the interest
payment to be paid on such date as set forth in the Indenture. For so long as
the Securities are listed on the Luxembourg Stock Exchange, the Company shall
also publish a notice of the requirement to pay Additional Interest in an
Authorized Newspaper.

         The interest (and Additional Interest, if any) so payable, and
punctually paid or duly provided for, on any interest payment date will, as
provided in the Indenture, be paid to the Person in whose name this Security (or
one or more Predecessor Securities) is registered at the close of business on
the regular record date for such interest, which shall be the March 15 or
September 15 (whether or not a Business Day), as the case may be, next preceding
such interest payment date. Any such interest not so punctually paid or duly
provided for will forthwith cease to be payable to the Holder on such regular
record date and may either be paid to the Person in whose name this Security (or
one or more Predecessor Securities) is registered at the close of business on a
special record date for the payment of such Defaulted Interest to be fixed by
the Trustee, notice whereof shall be given to Holders of Securities of this
series not less than 10 days prior to such special record date, or be paid at
any time in any other lawful manner not inconsistent with the requirements of
any securities exchange on which the Securities of this series may be listed,
and upon such notice as may be required by such exchange, all as more fully
provided in the Indenture.

         Payment of the principal of (and premium, if any) and interest (and
Additional Interest, if any) on this Security will be made at the office or
agency of the Company maintained for that purpose in the Borough of Manhattan,
The City of New York, in such coin or currency of the United States of America
as at the time of payment is legal tender for payment of public and private
debts; provided, however, that at the option of the Company payment of interest
may be made by check mailed to the address of the Person entitled thereto as
such address shall appear in the Security Register or by wire transfer to an
account maintained by the Person entitled thereto as specified in the Security
Register, provided that such Person shall have given the Trustee written wire
instructions at least five Business Days prior to the applicable Interest
Payment Date.

                       [FORM OF REVERSE SIDE OF SECURITY]

                            7.45% Debenture due 2031



         Section 1. Indenture

         The Company issued the Securities under an Indenture, dated as of March
15, 2001, between the Company and the Trustee, and Supplemental Indenture No. 1
thereto, dated as of March 29, 2001 (collectively, the "Indenture"). The terms
of the Securities include those stated in the Indenture and those made part of
the Indenture by reference to the Trust Indenture Act as in effect on the date
of the Indenture. Terms defined in the Indenture and not defined herein have the
meanings ascribed thereto in the Indenture. The Securities are subject to all
terms and provisions of the Indenture, and Securityholders are referred to the
Indenture and the Trust Indenture Act for a statement of such terms and
provisions.

         The Securities are senior unsecured obligations of the Company
initially limited to $1,100,000,000 aggregate principal amount at any one time
outstanding. This Security is one of the Initial Securities referred to in the
Indenture. The Securities include the Initial Securities and any Exchange
Securities and Private Exchange Securities issued in exchange for Initial
Securities. The Initial Securities, the Exchange Securities and the Private
Exchange Securities are treated as a single class of securities under the
Indenture.

         Section 2. Optional Redemption

         The Securities may be redeemed at the option of the Company, in whole
or in part, at any time or from time to time. The redemption price for the
Securities to be redeemed on any redemption date will be equal to the greater
of: (i)100% of the principal amount of the Securities being redeemed on the
redemption date; or (ii) the sum of the present values of the remaining
scheduled payments of principal and interest on the Securities being redeemed on
that redemption date (not including any portion of any payments of interest
accrued to the redemption date) discounted to the redemption date on a
semiannual basis at the Treasury Rate, plus 35 basis points, as determined by
the Reference Treasury Dealer, plus accrued and unpaid interest thereon to the
redemption date. Notwithstanding the foregoing, installments of interest on
Securities that are due and payable on interest payment dates falling on or
prior to a redemption date will be payable on the interest payment date to the
registered Holders as of the close of business on the relevant record date
according to the Securities and the Indenture. The redemption price will be
calculated on the basis of a 360-day year consisting of twelve 30-day months.

         The Company shall mail notice of any redemption at least 30 days but
not more than 60 days before the redemption date to each registered Holder of
the Securities to be redeemed. Once notice of redemption is mailed, the
Securities called for redemption will become due and payable on the redemption
date and at the applicable redemption price, plus accrued and unpaid interest to
the redemption date.

         "Treasury Rate" means, with respect to any redemption date, the rate
per annum equal to the semiannual equivalent yield to maturity of the Comparable
Treasury Issue, assuming a price



                                       A2-5
<PAGE>   59

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

         "Comparable Treasury Price" means, with respect to any redemption date,
(A) the average of the Reference Treasury Dealer Quotations for such redemption
date, after excluding the highest and lowest such Reference Treasury Dealer
Quotations, or (B) if the trustee obtains fewer than three such Reference
Treasury Dealer Quotations, the average of all such Quotations, or (C) if only
one Reference Treasury Dealer Quotation is received, such Quotation.

         "Reference Treasury Dealer" means (A) Salomon Smith Barney Inc., Chase
Securities Inc. or Banc of America Securities LLC (or their respective
affiliates which are Primary Treasury Dealers), and their respective successors;
provided, however, that if any of the foregoing shall cease to be a primary U.S.
Government securities dealer in New York City (a "Primary Treasury Dealer"), we
will substitute therefor another Primary Treasury Dealer; and (B) any other
Primary Treasury Dealer(s) selected by us.

         "Reference Treasury Dealer Quotation" 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 5:00 p.m. (New York
City time) on the third business day preceding such redemption date.

         Section 3. Sinking Fund

         The Securities are not subject to any sinking fund.

         Section 4. Notice of Redemption

         Notice of redemption will be mailed by first-class mail at least 30
days but not more than 60 days before the redemption date to each Holder of
Securities to be redeemed at his or her registered address. Securities in
denominations larger than $1,000 of principal amount may be redeemed in part but
only in whole multiples of $1,000 of principal amount. If money sufficient to
pay the redemption price of and accrued and unpaid interest and liquidated
damages, if any, on all Securities (or portions thereof) to be redeemed on the
redemption date is deposited with the Paying Agent on or before the redemption
date and certain other conditions are satisfied, on and after such date interest
ceases to accrue on such Securities (or such portions thereof) called for
redemption.

         Section 5. Denominations; Transfer; Exchange

         The Securities are in registered form without coupons in denominations
of $1,000 and whole multiples of $1,000. A Holder may transfer or exchange
Securities in accordance with the



                                       A2-6
<PAGE>   60

Indenture. Upon any transfer or exchange, the Registrar and the Trustee may
require a Holder, among other things, to furnish appropriate endorsements or
transfer documents and to pay any taxes required by law or permitted by the
Indenture. The Registrar need not register the transfer of or exchange any
Securities selected for redemption (except, in the case of a Security to be
redeemed in part, the portion of the Security not to be redeemed) or to transfer
or exchange any Securities for a period of 15 days prior to the mailing of a
notice of redemption of Securities to be redeemed.

         Section 6. Persons Deemed Owners

         The registered Holder of this Security may be treated as the owner of
it for all purposes.

         Section 7. Unclaimed Money

         If money for the payment of principal or interest remains unclaimed for
two years, the Trustee or Paying Agent shall pay the money back to the Company
at its written request unless an abandoned property law designates another
Person. After any such payment, Holders entitled to the money must look only to
the Company and not to the Trustee for payment.

         Section 8. Discharge and Defeasance

         Subject to certain conditions, the Company at any time may terminate
some of or all its obligations under the Securities and the Indenture if the
Company deposits with the Trustee money or U.S. Government Obligations for the
payment of principal and interest on the Securities to redemption or maturity,
as the case may be.

         Section 9. Trustee Dealings with the Company

         Subject to certain limitations imposed by the Trust Indenture Act, the
Trustee under the Indenture, in its individual or any other capacity, may become
the owner or pledgee of Securities and may otherwise deal with and collect
obligations owed to it by the Company or its Affiliates and may otherwise deal
with the Company or its Affiliates with the same rights it would have if it were
not Trustee.

         Section 10. No Recourse Against Others

         A director, officer, employee or stockholder, as such, of the Company
shall not have any liability for any obligations of the Company under the
Securities or the Indenture or for any claim based on, in respect of or by
reason of such obligations or their creation. By accepting a Security, each
Securityholder waives and releases all such liability. The waiver and release
are part of the consideration for the issue of the Securities.

         Section 11. Authentication

         This Security shall not be valid until an authorized signatory of the
Trustee (or an authenticating agent) manually signs the certificate of
authentication on the other side of this Security.



                                       A2-7
<PAGE>   61

         Section 12. Governing Law

         THIS SECURITY SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH,
THE LAWS OF THE STATE OF NEW YORK BUT WITHOUT GIVING EFFECT TO APPLICABLE
PRINCIPLES OF CONFLICTS OF LAW TO THE EXTENT THAT THE APPLICATION OF THE LAWS OF
ANOTHER JURISDICTION WOULD BE REQUIRED THEREBY.

         Section 13. CUSIP Numbers

         Pursuant to a recommendation promulgated by the Committee on Uniform
Security Identification Procedures, the Company has caused CUSIP numbers to be
printed on the Securities and has directed the Trustee to use CUSIP numbers in
notices of redemption as a convenience to Securityholders. No representation is

Name:________________________

Taxpayer ID Number:__________


         The undersigned represents and warrants to you that:

         1._______We are an institutional "accredited investor" (as defined in
Rule 501(a)(1), (2), (3) or (7) under the Securities Act of 1933, as amended
(the "Securities Act")), purchasing for our own account or for the account of
such an institutional "accredited investor" at least $250,000 principal amount
of the Securities, and we are acquiring the Securities not with a view to, or
for offer or sale in connection with, any distribution in violation of the
Securities Act. We have such knowledge and experience in financial and business
matters as to be capable of evaluating the merits and risks of our investment in
the Securities, and we invest in or purchase securities similar to the
Securities in the normal course of our business. We, and any accounts for which
we are acting, are each able to bear the economic risk of our or its investment.

         2._______We understand that the Securities have not been registered
under the Securities Act and, unless so registered, may not be sold except as
permitted in the following sentence. We agree on our own behalf and on behalf of
any investor account for which we are purchasing the Securities to offer, sell
or otherwise transfer such Securities prior to the date that is two years after
the later of the date of original issue and the last date on which the Company
or any affiliate

of the Company was the owner of such Securities (or any predecessor thereto)
(the "Resale Restriction Termination Date") only (a) to the Company, (b)
pursuant to a registration statement that has been declared effective under the
Securities Act, (c) in a transaction complying with the requirements of Rule
144A under the Securities Act ("Rule 144A"), to a person we reasonably believe
is a qualified institutional buyer under Rule 144A (a "QIB") that is purchasing
for its own account or for the account of a QIB and to whom notice is given that
the transfer is being made in reliance on Rule 144A, (d) in an offshore
transaction within the meaning of, and in compliance with, Regulation S under
the Securities Act, (e) to an institutional "accredited investor" within the
meaning of Rule 501(a)(1), (2), (3) or (7) under the Securities Act that is
purchasing for its own account or for the account of such an institutional
"accredited investor", in each case in a minimum principal amount of Securities
of $250,000, or (f) pursuant to any other available exemption from the
registration requirements of the Securities Act, subject in each of the
foregoing cases to any requirement of law that the disposition of our property
or the property of such investor account or accounts be at all times within our
or their control and in compliance with any applicable state securities laws.
The foregoing restrictions on resale will not apply subsequent to the Resale
Restriction Termination Date. If any resale or other transfer of the Securities
is proposed to be made pursuant to clause (e) above prior to the Resale
Restriction Termination Date, the transferor shall deliver a letter from the
transferee substantially in the form of this letter to the Company and the
Trustee, which shall provide, among other things, that the transferee is an
institutional "accredited investor" within the meaning of Rule 501(a)(1), (2),
(3) or (7) under the Securities Act and that it is acquiring such Securities for
investment purposes and not for distribution in violation of the Securities Act.
Each purchaser acknowledges that the Company and the Trustee reserve the right
prior to the offer, sale or other transfer prior to the Resale Restriction
Termination Date of the Securities pursuant to clause (d), (e) or (f) above to
require the delivery of an opinion of counsel, certifications or other
information satisfactory to the Company and the Trustee.
