                             4.375% NOTES DUE 2007

     1. Indenture; Notes. This Note is one of a duly authorized series of
Securities of the Company designated as the "4.375% Notes due 2007" (the
"Notes"), initially issued in an aggregate principal amount of $1,000,000,000 on
July 12, 2002 and, as a result of the further issuance of $500,000,000 aggregate
principal amount of Notes on September 20, 2002, now issued in an aggregate
principal amount of $1,500,000,000. Such series of Securities has been
established pursuant to, and is one of an indefinite number of series of debt
securities of the Company, issued or issuable under and pursuant to, the
Indenture, dated as of July 5, 2001 (the "Indenture"), duly executed and
delivered by the Company, Wal-Mart Cayman (Euro) Finance Co., Wal-Mart Cayman
(Canadian) Finance Co. and Wal-Mart Cayman (Sterling) Finance Co. as Issuers,
the Company as Guarantor and Bank One Trust Company, NA, as Trustee (the
"Trustee"), to which Indenture and all indentures supplemental thereto reference
is hereby made for a statement of the rights, limitations of rights,
obligations, duties and immunities thereunder of the Trustee, the Company and
the holders of the Notes and of the terms upon which this Note is, and is to be,
authenticated and delivered. The terms, conditions and provisions of the Notes
are those stated in the Indenture, those made part of the Indenture by reference
to the Trust Indenture Act of 1939, as amended (the "Trust Indenture Act"), and
those set forth in this Note. To the extent that the terms, conditions and other
provisions of this Note modify, supplement or are inconsistent with those of the
Indenture, then the terms, conditions and other provisions of this Note shall
govern.

     All capitalized terms which are used but not defined in this Note shall
have the meanings assigned to them in the Indenture.

     The Company may, without the consent of the holders, issue and sell
additional Securities ranking equally with the Notes and otherwise identical in
all respects (except for their date of issue, issue price and the date from
which interest payments thereon shall accrue) so that such additional Securities
shall be consolidated and form a single series with the Notes; provided,
however, that no additional Securities of any existing or new series may be
issued under the Indenture if an Event of Default has occurred and remains
uncured thereunder.

     2. Ranking. The Notes shall constitute the senior unsecured debt
obligations of the Company and shall rank equally in right of payment among
themselves and with all other existing and future senior, unsecured and
unsubordinated debt obligations of the Company.

     3. Payment of Overdue Amounts. The Company shall pay interest, calculated
on the basis of a 360-day year of twelve 30-day months, on overdue principal and
overdue installments of interest, if any, from time to time on demand at the
interest rate borne by the Notes to the extent lawful.

     4. Payment of Additional Amounts; Redemption Upon a Tax Event. (a) Payment
of Additional Amounts. The Company shall pay to the holder of this Note who is a
United States Alien (as defined below) such additional amounts as may be
necessary so that every net payment of principal of and interest on this Note to
such holder, after deduction or withholding for or on account of any present or
future tax, assessment or other governmental charge imposed upon such holder by
the United States of America or any taxing authority thereof or therein, will
not be less than the amount provided in the Notes to be then due and payable
(such amounts, the "Additional Amounts"); provided, however, that the Company
shall not be required to make any payment of Additional Amounts for or on
account of:

<PAGE>

          (i) any tax, assessment or other governmental charge that would not
     have been imposed but for (A) the existence of any present or former
     connection between such holder, or between a fiduciary, settlor,
     beneficiary of, member or shareholder of, or possessor of a power over,
     such holder, if such holder is an estate, trust, partnership or
     corporation, and the United States including, without limitation, such
     holder, or such fiduciary, settlor, beneficiary, member, shareholder or
     possessor, being or having been a citizen or resident of the United States
     of America or treated as a resident thereof or being or having been engaged
     in trade or business or present in the United States of America, or (B) the
     presentation of this Note for payment on a date more than 30 days after the
     later of (x) the date on which such payment becomes due and payable and (y)
     the date on which payment thereof is duly provided for;

          (ii) any estate, inheritance, gift, sales, transfer, excise, personal
     property or similar tax, assessment or other governmental charge;

          (iii) any tax, assessment or other governmental charge imposed by
     reason of such holder's past or present status as a passive foreign
     investment company, a controlled foreign corporation, a personal holding
     company or foreign personal holding company with respect to the United
     States of America, or as a corporation which accumulates earnings to avoid
     United States federal income tax;

          (iv) any tax, assessment or other governmental charge which is payable
     otherwise than by withholding from payment of principal of or interest on
     this Note;

          (v) any tax, assessment or other governmental charge required to be
     withheld by any paying agent from any payment of principal of or interest
     on this Note if such payment can be made without withholding by any other
     paying agent;

          (vi) any tax, assessment or other governmental charge which would not
     have been imposed but for the failure to comply with certification,
     information, documentation or other reporting requirements concerning the
     nationality, residence, identity or connections with the United States of
     America of the holder or beneficial owner of this Note, 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;

          (vii) any tax, assessment or other governmental charge imposed on
     interest received by (A) a 10% shareholder (as defined in Section
     871(h)(3)(B) of the United States Internal Revenue Code of 1986, as amended
     (the "Code"), and the regulations that may be promulgated thereunder) of
     the Company or (B) a controlled foreign corporation with respect to the
     Company within the meaning of the Code; or

          (viii) any combination of items (i), (ii), (iii), (iv), (v), (vi) and
     (vii) in this Section 4(a);

nor shall any Additional Amounts be paid to any holder who is a fiduciary
partnership or other than the sole beneficial owner of this Note to the extent
that a beneficiary or settlor with respect to such fiduciary, or a member of
such partnership or a beneficial owner thereof would not have been entitled to
the payment of such Additional Amounts had such beneficiary, settlor, member or
beneficial owner been the holder.

     "United States Alien" means any corporation, partnership, individual or
fiduciary that is, as to the United States of America, a foreign corporation, a
non-resident alien individual who has not made a valid election to be treated as
a United States resident, a non-resident fiduciary of a foreign estate or trust,
or a foreign partnership one or more of the members of which is, as to the
United States

<PAGE>

of America, a foreign corporation, a non-resident alien individual or a
non-resident fiduciary of a foreign estate or trust.

     (b) Redemption Upon a Tax Event. The Notes may be redeemed at the option of
the Company in whole, but not in part, on a date (such date, the "Tax Redemption
Date") to be fixed by the Company on not more than 60 days' and not less than 30
days' notice, at a redemption price equal to 100% of the principal amount of the
Notes (the "Redemption Price") plus accrued but unpaid interest, if any,
thereon, if the Company determines that as a result of any change in or
amendment to the laws, treaties, regulations or rulings of the United States of
America or any political subdivision or taxing authority thereof, or any
proposed change in such laws, treaties, regulations or rulings, or any change in
the official application, enforcement or interpretation of such laws, treaties,
regulations or rulings, including a holding by a court of competent jurisdiction
in the United States of America, or any other action, other than an action
predicated on laws generally known on or before July 9, 2002 except for
proposals before the U.S. Congress before such date, taken by any taxing
authority or a court of competent jurisdiction in the United States of America,
or the official proposal of any such action, whether or not such action or
proposal was taken or made with respect to the Company, (A) the Company has or
will become obligated to pay Additional Amounts or (B) there is a substantial
possibility that the Company will be required to pay such Additional Amounts.

     Prior to the publication of any notice of redemption pursuant to Section 15
hereof, the Company shall deliver to the Trustee (1) an Officers' Certificate
stating that the Company is entitled to effect such redemption and setting forth
a statement of facts showing that the conditions precedent to the rights of the
Company to so redeem have occurred and (2) an Opinion of Counsel to such effect
based on such statement of facts.

     If the Company elects to redeem the Notes pursuant to this Section 4(b),
then it shall give notice to the holders pursuant to Section 15 hereof.

          The notice of redemption, shall specify the following:

          (i) the Tax Redemption Date;

          (ii) a brief statement to the effect that the Notes are being redeemed

     statement of the facts permitting such redemption;

          (iii) that on the Tax Redemption Date, the Redemption Price, plus
     accrued but unpaid interest on the Notes, if any, will become due and
     payable;

          (iv) the amount of the Redemption Price and accrued but unpaid
     interest, if any, that will be due and payable on the Notes on the Tax
     Redemption Date;

          (v) the place or places of payment of the amounts due under clause
     (iv) above;

          (vi) that payment of the amounts due under clause (iv) above will be

          (vii) that, following the redemption of the Notes pursuant to this
     Section 4(b), interest shall cease to accrue thereon.

     The notice of redemption regarding the Notes shall be, at the election of
the Company, given by the Company or, at the Company's request, by the Trustee
in the name and at the expense of

<PAGE>

the Company.

     On or before the opening of business on any Tax Redemption Date, the
Company shall deposit with the Trustee or with the Paying Agent or, if the
Company is acting as its own paying agent, segregate and hold in trust as
provided in Section 5.03 of the Indenture, an amount of money sufficient to pay
the Redemption Price of, and except if the Tax Redemption Date shall be an
Interest Payment Date, accrued but unpaid interest on, the Notes to be redeemed
on the Tax Redemption Date.

     The notice of redemption having been given as specified above, the Notes
shall, on the Tax Redemption Date, become due and payable at the Redemption
Price, and from and after such date, unless the Company shall default in the
payment of the Redemption Price and accrued but unpaid interest, if any, the
Notes shall cease to bear interest. Upon surrender of the Notes for redemption
in accordance with such notice, the Notes shall be paid by the Company at the
Redemption Price, together with accrued but unpaid interest, if any, to the Tax
Redemption Date.

     If the Notes, having been called for redemption, shall not be so paid upon
surrender thereof for redemption, the Redemption Price shall, until paid, bear
interest from the Tax Redemption Date at the interest rate borne by this Note.

     5. Place and Method of Payment. The Company shall pay principal of and
interest on the Notes at the office or agency of the Paying Agent in the Borough
of Manhattan, The City of New York; provided, however, that at the option of the
Company, the Company may pay interest by check mailed to the person entitled
thereto at such person's address as it appears on the Registry for the Notes.

     6. Defeasance of the Notes. Sections 11.02, 11.03 and 11.04 of the
Indenture shall apply to the Notes.

maturity, other than as set forth in Section 4(b) hereof, and are not subject to
a sinking fund.

     8. Amendment and Modification. Article Nine of the Indenture contains
provisions for the amendment or modification of the Indenture and the Notes
without the consent of the holders in certain circumstances and requiring the
consent of holders of not less than a majority in aggregate principal amount of
the Notes and Securities of other series that would be affected in certain other
circumstances. However, the Indenture requires the consent of each holder of the
Notes and Securities of other series that would be affected for certain
specified amendments or modifications of the Indenture and the Notes. These
provisions of the Indenture, which provide for, among other things, the
execution of supplemental indentures, are applicable to the Notes.

     9. Default; Waiver. If an Event of Default with respect to the Notes shall
occur and be continuing, then either the Trustee or the Holders of not less than
25% in aggregate principal amount of the Notes of this series then Outstanding
may declare the aggregate principal amount of the Notes of this series to be
immediately due and payable in the manner, with the effect and subject to the
conditions provided in the Indenture. The Indenture provides that in the event
of such a declaration, the holders of a majority in aggregate principal amount
of all of the Notes of this series then outstanding, voting as a separate class,
in accordance with the provisions of, and in the circumstances provided by, the
Indenture, may rescind and annul the declaration and its consequences and the
related default and its consequences may be waived with respect to all of the
Notes.

     10. Absolute Obligation. No reference herein to the Indenture and no
provisions of the Notes or of the Indenture shall alter or impair the obligation
of the Company, which is absolute and unconditional, to pay the principal of and
interest on this Note at the place, at the time and in the coin or

<PAGE>

currency herein prescribed.

     11. Form and Denominations; Global Notes; Definitive Notes. The Notes are
being issued in registered form without coupons in denominations of $1,000 and
multiples of $1,000. The Notes are being issued in the form of global notes
(each, a "Global Note"), evidencing all or any portion of the Notes and
registered in the name of DTC or its nominee (including their respective
successors) as Depositary under the Indenture. The Notes shall be issued in
certificated form (each, a "Definitive Note") only in the following limited
circumstances: (1) the Depositary is at any time unwilling or unable to continue
as Depositary or ceases to be a clearing agency registered under applicable law,
and a successor depositary is not appointed by the Company within 90 days after
the Company receives such notice or becomes aware of such ineligibility, (2) the
Company delivers to the Trustee a Company Order to the effect that this Note
shall be exchangeable for Definitive Notes or (3) an Event of Default has
occurred and is continuing with respect to the Notes, in each such case this
Note shall be exchangeable for Definitive Notes in an equal aggregate principal
amount. Such Definitive Notes shall be registered in such name or names as the
Depositary shall instruct the Trustee.

     12. Registration, Transfer and Exchange. As provided in the Indenture and
subject to certain limitations therein set forth, the Company shall provide for
the registration of the Notes and the transfer and exchange of the Notes,
whether in global or Definitive form. At the option of the holders, at any
office or agency designated and maintained by the Company for such purpose (the
"Transfer Agent") pursuant to the provisions of the Indenture, and in the manner
and subject to the limitations provided in the Indenture, but without the
payment of any service charge, except for any transfer tax or other governmental
charges imposed in connection therewith subject to Section 4 hereof, the Notes
may be transferred or exchanged for an equal aggregate principal amount of the
Notes of like tenor and of other authorized denominations upon surrender and
cancellation of the Notes upon any such transfer.

     The Company, the Trustee, and any agent of the Company or of the Trustee
may deem and treat the holder as the absolute owner of this Note (whether or not
the Notes shall be overdue and notwithstanding any notation of ownership or
other writing hereon), for the purpose of receiving payments hereon, or on
account hereof, and for all other purposes, and neither the Company nor the
Trustee nor any agent of the Company or of the Trustee shall be affected by any
notice to the contrary. All such payments made to or upon the order of such
holder shall, to the extent of the amount or amounts paid, effectually satisfy
and discharge liability for moneys payable on this Note.

     Notwithstanding the preceding paragraphs of this Section 12, any
registration of transfer or exchange of a Global Note shall be subject to the
terms of the legend appearing on the initial page thereof.

     13. No Recourse Against Others. No recourse under or upon any obligation,
covenant or agreement of the Company arising under or set forth in the Notes or
under the Indenture, or for any claim based thereon or otherwise in respect
thereof, shall be had against any incorporator, stockholder, officer or
director, as such, past, present or future, of the Company or of any successor
corporation, either directly or through the Company or any successor
corporation, whether by virtue of any constitution, statute or rule of law or by
the enforcement of any assessment or penalty or otherwise, any and all such
personal liability, either at common law or in equity or by constitution or
statute, of, and any and all such rights and claims against, every such
incorporator, stockholder, officer or director, as such, being, by the
acceptance hereof and as part of the consideration for the issue hereof,
expressly waived and released.

     14. Appointment of Agents. Bank One Trust Company, NA is hereby appointed
the Registrar for the purpose of registering the Notes and transfers and
exchanges of the Notes pursuant to the Indenture and this Note, Paying Agent
pursuant to Section 3.04 of the Indenture and Transfer Agent

<PAGE>

with respect to the Notes at its offices in the Borough of Manhattan, The City
of New York.

     15. Notices. If the Company is required to give notice to the holders of
the Notes pursuant to the terms of the Indenture, then it shall do so by the
means and in the manner set forth in Section 1.06 of the Indenture.

     In addition, the Company shall give notices to the holders of the Notes by
publication in a leading daily newspaper in The City of New York and in London.
Initially, such publication shall be made in The City of New York in The Wall
Street Journal and in London in the Financial Times. Any such notice shall be
deemed to have been given on the date of publication or, if published more than
once, on the date of the first publication.

     16. Separability. In case any provision of the Indenture or the Notes
shall, for any reason, be held to be invalid, illegal or unenforceable, then the
validity, legality and enforceability of the remaining provisions thereof and
hereof shall not in any way be affected or impaired thereby.

     17. GOVERNING LAW. THE NOTES SHALL BE GOVERNED BY, AND CONSTRUED IN
ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.

2.1 Conversion Rights. The Company and Parent hereby agree in accordance with
Section 4.11 of the Indenture that the Holder of each Security outstanding at

                          III. GUARANTEE OF OBLIGATIONS

3.1 Guarantee. Parent hereby fully and unconditionally guarantees to each Holder
of Securities and to the Trustee and its successors and assigns (i) the punctual
payment when due, whether at stated maturity, by acceleration, redemption or
otherwise, of the principal of, premium, if any, and interest (including
Additional Interest, if any) on the Securities according to the terms of the
Securities and as more fully described in the Indenture, as amended and

the Company under the Indenture, as amended and supplemented by this First
Supplemental Indenture, and under the Securities (the obligations of the Company
described in the foregoing clauses (i) and (ii) being hereinafter referred to as
the "Obligations"). All payments of cash made by Parent pursuant to this Article
III shall be paid in lawful money of the United States of America. Each and
every breach or default of payment or performance of any of the Obligations
shall immediately give rise to a separate cause of action hereunder against the
Company and Parent, and separate suits may be brought hereunder against the
Company and Parent, as each cause of action arises. Notwithstanding the
foregoing, the Company shall remain obligated under the Indenture and the
Securities, in accordance with the terms of the Indenture, as amended and
supplemented by this First Supplemental Indenture. The agreements of Parent set
forth in this Section 3.1 are cumulative of and in addition to the agreements of
the Company and Parent under the Indenture, as amended and supplemented by this
First Supplemental Indenture.

3.2 Unconditional Nature of Obligations. The obligations of Parent under this
Article III shall be absolute and unconditional and shall remain in full force

<PAGE>

been paid or provided for in full in accordance with the provisions of the
Indenture, and such obligation shall not be affected, modified or impaired upon
the happening from time to time of any event, including without limitation any
of the following, whether or not with notice to, or with the consent of, Parent:

        (a)    the waiver, surrender, compromise, settlement, release or
               termination of any or all of the obligations, covenants or
               agreements of the Company under the Indenture, as amended and
               supplemented by this First Supplemental Indenture, and the
               Securities;

        (b)    the failure to give notice to Parent of the occurrence of a
               breach or default under the Indenture, as amended and
               supplemented by this First Supplemental Indenture, or the
               Securities;

        (c)    the waiver, compromise or release of the payment, performance or
               observance by the Company or by Parent, respectively, of any or
               all of the obligations, covenants or agreements contained in the
               Indenture, as amended and supplemented by this First Supplemental
               Indenture;

        (d)    the extension of the time for payment of any principal of or
               interest or any redemption premium on any Security or for any
               other payment under the Indenture or of the time for performance
               of any other obligations, covenants or agreements under or
               arising out of the Indenture, as amended and supplemented by this
               First Supplemental Indenture;

        (e)    the modification or amendment (whether material or otherwise) of
               any obligation, covenant or agreement set forth in the Indenture,
               as amended and supplemented by this First Supplemental Indenture,
               or the Securities;

        (f)    any failure, omission or delay on the part of any Holder or the
               Trustee to enforce, assert or exercise any right, power or remedy
               conferred on it in or in connection with the Indenture, as
               amended and supplemented by this First Supplemental Indenture, or
               the Securities;

        (g)    the voluntary or involuntary liquidation, dissolution, sale or
               other disposition of all or substantially all the assets,
               marshalling of assets and liabilities, receivership, insolvency,
               bankruptcy, assignment for the benefit of creditors,
               reorganization, arrangement, composition with creditors or
               readjustment of, or other similar proceedings affecting Parent or
               the Company or any of the respective assets of either of them, or
               any allegation or contest of the validity of this Article III in
               any such proceeding;

        (h)    any defense based upon any legal disability of the Company or, to
               the extent permitted by law, any release, discharge, reduction or
               limitation of

                                       3
<PAGE>

               or with respect of any sums owing by the Company, or any other
               liability of the Company, to any Holder;

        (i)    to the extent permitted by law, the release or discharge of
               Parent by operation of law from the performance or observance of
               any obligation, covenant or agreement contained in this Article
               III;

        (j)    the default or failure of Parent fully to perform any of its
               obligations set forth in this Article III; or

        (k)    the invalidity or unenforceability of the Indenture (considered
               either separately or as amended and supplemented by this First
               Supplemental Indenture) or the Securities or any defense which
               the Company may have against any Holder.

        If any payment by the Company to the Trustee or to any Holder of any
Securities is rescinded or must be returned by the Trustee or such Holder, then
the obligations of Parent hereunder shall be reinstated with respect to such
payment.

        No set-off, counterclaim, reduction, or diminution of any obligation, or
any defense of any kind or nature which Parent has or may have against the
Trustee or any Holder of any Securities, shall be available hereunder to Parent
against the Trustee or such Holder to reduce or delay the payments of Parent
under this Article III.

        Parent assumes responsibility for being and remaining informed of the
financial condition of the Company and of all other circumstances bearing upon
the risk of nonpayment of amounts owing under the Securities which diligent
inquiry would reveal and agrees that no Holder of Securities shall have any duty
to advise Parent of information known to it regarding such condition or any such
circumstances.

3.3 Proceedings Against Parent. In the event of a default in the payment of
principal or any redemption premium on any Security when and as the same shall
become due, whether at the maturity thereof, by acceleration, call for
redemption or otherwise, or in the event of a default in the payment of any
interest on any Security when and as the same shall become due, the Trustee or
any Holder of such Security shall have the right, at its option, to immediately
proceed first and directly against Parent under this Article III without
proceeding against the Company or exhausting any other remedies which it may
have.

                       IV. SUBORDINATION OF THE GUARANTEE

4.1 Subordination. The obligations of Parent under Article III of this First
Supplemental Indenture with respect to the payment of the principal of, premium,
if any, and interest (including Additional Interest, if any) on all Securities
(including, but not limited to, the Redemption Price or Provisional Redemption
Price, as the case may be,

                                       4
<PAGE>

with respect to the Securities called for redemption or the Change in Control
Purchase Price with respect to the Securities subject to purchase in accordance
with the Indenture) shall, to the extent and in the manner set forth in this
Article IV, be subordinated and subject in right of payment to the prior payment
in full in cash or payment satisfactory to the holders of Parent Senior
Indebtedness of all Parent Senior Indebtedness and the subordination is for the
benefit of Parent Senior Indebtedness.

        Notwithstanding anything herein to the contrary, no provision of this
Article IV shall (i) prevent the occurrence of any default or Event of Default
under the Indenture, (ii) in any way affect, alter, qualify or modify any of the
obligations of the Company under the Indenture, as amended and supplemented by
this First Supplemental Indenture, or (iii) in any way affect, alter, qualify or
modify the rights of a Holder of Securities to convert said Securities into
Common Stock in accordance with the provisions of the Indenture, as amended and
supplemented by this First Supplemental Indenture.

        4.2 Payments to Holders. Parent shall not make any payment pursuant to
its obligations under Article III of this First Supplemental Indenture with
respect to any of the Obligations if:

        (a) a default in the payment of principal, premium, interest, rent or
other obligations due on any Designated Parent Senior Indebtedness occurs and is
continuing (or, in the case of Designated Parent Senior Indebtedness for which
there is a period of grace, in the event of such a default that continues beyond
the period of grace, if any, specified in the instrument or lease evidencing
such Designated Parent Senior Indebtedness), unless and until such default shall
have been cured or waived or shall have ceased to exist; or

        (b) a default, other than a payment default, on any Designated Parent
Senior Indebtedness occurs and is continuing that then permits holders of such
Designated Parent Senior Indebtedness to accelerate its maturity and the Trustee
receives a notice of the default (a "Parent Payment Blockage Notice") from a
Representative or holder of Designated Parent Senior Indebtedness or Parent.

        Subject to the provisions of Section 4.5 of this First Supplemental
Indenture, if the Trustee receives any Parent Payment Blockage Notice pursuant
to clause (b) above, no subsequent Parent Payment Blockage Notice shall be
effective for purposes of this Section 4.2 unless and until at least 365 days
shall have elapsed since the initial effectiveness of the immediately prior
Parent Payment Blockage Notice. No nonpayment default that existed or was
continuing on the date of delivery of any Parent Payment Blockage Notice to the
Trustee (unless such default was waived, cured or otherwise ceased to exist and
thereafter subsequently reoccurred) shall be, or be made, the basis for a
subsequent Parent Payment Blockage Notice.

                                       5
<PAGE>

        Parent may and shall resume payments on and distributions in respect of
the Securities pursuant to its obligations under Article III of this First
Supplemental Indenture upon the earlier of:

        (1) in the case of a default referred to in clause (a) above, the date
upon which the default is cured or waived or ceases to exist, or

        (2) in the case of a default referred to in clause (b) above, the
earlier of the date on which such default is cured or waived or ceases to exist
or 179 days pass after the date on which the applicable Parent Payment Blockage
Notice is received, if the maturity of such Designated Parent Senior
Indebtedness has not been accelerated, unless this Article IV otherwise
prohibits the payment or distribution at the time of such payment or
distribution.

        Upon any payment by Parent, or distribution of assets of Parent of any
kind or character, whether in cash, property or securities, to creditors upon
any dissolution or winding-up or liquidation or reorganization of Parent
(whether voluntary or involuntary) or in bankruptcy, insolvency, receivership or
similar proceedings, all amounts due or to become due upon all Parent Senior
Indebtedness shall first be paid in full in cash, or other payments satisfactory
to the holders of Parent Senior Indebtedness before any payment is made on
account of the principal of, premium, if any, or interest (including Additional
Interest, if any) on the Securities pursuant to Article III of this First
Supplemental Indenture (except payments made pursuant to Article 10 of the
Indenture from monies deposited with the Trustee pursuant thereto prior to
commencement of proceedings for such dissolution, winding-up, liquidation or
reorganization); and upon any such dissolution or winding-up or liquidation or
reorganization of Parent or bankruptcy, insolvency, receivership or other
proceeding, any payment by Parent, or distribution of assets of Parent of any
kind or character, whether in cash, property or securities, to which the Holders
of the Securities or the Trustee would be entitled, except for the provision of
this Article IV, shall (except as aforesaid) be paid by Parent or by any
receiver, trustee in bankruptcy, liquidating trustee, agent or other Person
making such payment or distribution, or by the Holders of the Securities or by
the Trustee under the Indenture, as amended and supplemented by this First
Supplemental Indenture, if received by them or it, directly to the holders of
Parent Senior Indebtedness (pro rata to such holders on the basis of the
respective amounts of Parent Senior Indebtedness held by such holders, or as
otherwise required by law or a court order) or their representative or
representatives, or to the trustee or trustees under any indenture pursuant to
which any instruments evidencing any Parent Senior Indebtedness may have been
issued, as their respective interests may appear, to the extent necessary to pay
all Parent Senior Indebtedness in full in cash, or other payment satisfactory to
the holders of Parent Senior Indebtedness, after giving effect to any concurrent
payment or distribution to or for the holders of Parent Senior Indebtedness,
before any payment or distribution is made by Parent to the Holders of the
Securities or to the Trustee in respect of the Securities.

                                       6
<PAGE>

        For purposes of this Article IV, the words, "cash, property or
securities" shall not be deemed to include shares of stock of Parent as
reorganized or readjusted, or securities of Parent or any other corporation
provided for by a plan of reorganization or readjustment, the payment of which
is subordinated at least to the extent provided in this Article IV with respect
to the Securities to the payment of all Parent Senior Indebtedness which may at
the time be outstanding; provided that (i) the Parent Senior Indebtedness is
assumed by the new corporation, if any, resulting from any reorganization or
readjustment, and (ii) the rights of the holders of Parent Senior Indebtedness
(other than leases which are not assumed by Parent or the new corporation, as
the case may be) are not, without the consent of such holders, altered by such
reorganization or readjustment.

        In the event of the acceleration of the Securities because of an Event
of Default and a demand for payment is made on Parent pursuant to Article III of
this First Supplemental Indenture, no payment or distribution by Parent pursuant
to any of its obligations under Article III of this First Supplemental Indenture
shall be made to the Trustee or any Holder of Securities in respect of the
principal of, premium, if any, or interest (including Additional Interest, if
any) on the Securities, except payments and distributions made by the Trustee as
permitted by Section 4.5 of this First Supplemental Indenture, until all Parent
Senior Indebtedness has been paid in full in cash or other payment satisfactory
to the holders of Parent Senior Indebtedness or such acceleration is rescinded
in accordance with the terms of the Indenture. If payment of the Securities is
accelerated because of an Event of Default and a demand for payment is made on
Parent pursuant to Article III of this First Supplemental Indenture, Parent
shall promptly notify holders of Parent Senior Indebtedness of such
acceleration.

        In the event that, notwithstanding the foregoing provisions, any payment
or distribution of assets of Parent of any kind or character, whether in cash,
property or securities (including, without limitation, by way of setoff or
otherwise), prohibited by the foregoing provisions in this Section 4.2, shall be
received by the Trustee or the Holders of the Securities before all Parent
Senior Indebtedness is paid in full, in cash or other payment satisfactory to
the holders of Parent Senior Indebtedness, or provision is made for such payment
thereof in accordance with its terms in cash or other payment satisfactory to
the holders of Parent Senior Indebtedness, such payment or distribution shall be
held in trust for the benefit of and shall be paid over or delivered to the
holders of Parent Senior Indebtedness or their representative or
representatives, or to the trustee or trustees under any indenture pursuant to
which any instruments evidencing any Parent Senior Indebtedness may have been
issued, as their respective interests may appear, as calculated by Parent, for
application to the payment of all Parent Senior Indebtedness remaining unpaid to
the extent necessary to pay all Parent Senior Indebtedness in full, in cash or
other payment satisfactory to the holders of Parent Senior Indebtedness, after
giving effect to any concurrent payment or distribution to or for the holders of
such Parent Senior Indebtedness.

        Nothing in this Section 4.2 shall apply to claims of the Trustee under
or pursuant to Section 9.7 of the Indenture or to payments to the Trustee made
by Parent pursuant to

                                       7
<PAGE>

its obligations under Article III of this First Supplemental Indenture with
respect to Section 9.7 of the Indenture. This Section 4.2 shall be subject to
the further provisions of Section 4.5 of this First Supplemental Indenture.

4.3 Subrogation of Securities. Subject to the payment in full, in cash or other
payment satisfactory to the holders of Parent Senior Indebtedness, of all Parent
Senior Indebtedness, the rights of the Holders of the Securities shall be
subrogated to the extent of the payments or distributions made to the holders of
such Parent Senior Indebtedness pursuant to the provisions of this Article IV
(equally and ratably with the holders of all indebtedness of Parent which by its
express terms is subordinated to other indebtedness of Parent to substantially
the same extent as the Securities are subordinated and is entitled to like
rights of subrogation) to the rights of the holders of Parent Senior
Indebtedness to receive payments or distributions of cash, property or
securities of Parent applicable to the Parent Senior Indebtedness until the
principal, premium, if any, and interest (including Additional Interest, if any)
on the Securities shall be paid in full in cash or other payment satisfactory to
the holders of the Securities; and, for the purposes of such subrogation, no
payments or distributions to the holders of the Parent Senior Indebtedness of
any cash, property or securities to which the Holders of the Securities or the
Trustee would be entitled except for the provisions of this Article IV, and no
payment over pursuant to the provisions of this Article IV, to or for the
benefit of the holders of Parent Senior Indebtedness by Holders of the
Securities or the Trustee, shall, as between Parent, its creditors other than
holders of Parent Senior Indebtedness, and the Holders of the Securities, be
deemed to be a payment by Parent to or on account of the Parent Senior
Indebtedness; and no payments or distributions of cash, property or securities
to or for the benefit of the Holders of the Securities pursuant to the
subrogation provisions of this Article IV, which would otherwise have been paid
to the holders of Parent Senior Indebtedness shall be deemed to be a payment by
Parent to or for the account of the Securities. It is understood that the
provisions of this Article IV are and are intended solely for the purposes of
defining the relative rights of the Holders of the Securities, on the one hand,
and the holders of the Parent Senior Indebtedness, on the other hand.

        Nothing contained in this Article IV or elsewhere in this First
Supplemental Indenture is intended to or shall impair, as among Parent, its
creditors other than the holders of Parent Senior Indebtedness, and the Holders
of the Securities, the obligation of Parent, which is absolute and
unconditional, to make payments pursuant to its obligations under Article III of
this First Supplemental Indenture with respect to the payment of the principal
of (and premium, if any) and interest on the Securities as and when the same
shall become due and payable in accordance with their terms, or is intended to
or shall affect the relative rights of the Holders of the Securities and
creditors of Parent other than the holders of the Parent Senior Indebtedness,
nor shall anything herein or therein prevent the Trustee or the Holder of any
Security from exercising all remedies otherwise permitted by applicable law upon
default by Parent of its obligations under Article III of this First
Supplemental Indenture, subject to the rights, if any, under this Article IV of
the holders of Parent Senior Indebtedness in respect of cash, property or
securities of Parent received upon the exercise of any such remedy.

                                       8
<PAGE>

        Upon any payment or distribution of assets of Parent referred to in this
Article IV, the Trustee, subject to the provisions of Section 9.1 of the
Indenture, and the Holders of the Securities shall be entitled to rely upon any
order or decree made by any court of competent jurisdiction in which such
bankruptcy, dissolution, winding-up, liquidation or reorganization proceedings
are pending, or a certificate of the receiver, trustee in bankruptcy,
liquidating trustee, agent or other person making such payment or distribution,
delivered to the Trustee or to the Holders of the Securities, for the purpose of
ascertaining the persons entitled to participate in such distribution, the
holders of the Parent Senior Indebtedness and other indebtedness of Parent, the
amount thereof or payable thereon and all other facts pertinent thereto or to
this Article IV.

4.4 Authorization to Effect Subordination. Each Holder of a Security by the
Holder's acceptance thereof authorizes and directs the Trustee on the Holder's
behalf to take such action as may be necessary or appropriate to effectuate the
subordination as provided in this Article IV and appoints the Trustee to act as
the Holder's attorney-in-fact for any and all such purposes. If the Trustee does
not file a proper proof of claim or proof of debt in the form required in any
proceeding referred to in Section 4.3 hereof at least 30 days before the
expiration of the time to file such claim, the holders of any Parent Senior
Indebtedness or their representatives are hereby authorized to file an
appropriate claim for and on behalf of the Holders of the Securities.

4.5 Notice to Trustee. During any period for which a demand for payment by
Parent pursuant to Article III of this First Supplemental Indenture remains
outstanding, Parent shall give prompt written notice in the form of an Officers'
Certificate to a Trust Officer of the Trustee and to any Paying Agent of any
fact known to Parent which would prohibit the making of any payment of monies to
or by the Trustee or any Paying Agent in respect of the Securities pursuant to
the provisions of this Article IV. Notwithstanding the provisions of this
Article IV or any other provision of the Indenture, as amended and supplemented
by this First Supplemental Indenture, the Trustee shall not be charged with
knowledge of the existence of any facts which would prohibit the making of any
payment of monies to or by the Trustee in respect of the Securities pursuant to
the provisions of this Article IV, unless and until a Trust Officer of the
Trustee shall have received written notice thereof at the Corporate Trust Office
from Parent (in the form of an Officers' Certificate) or a Representative or a
Holder or Holders of Parent Senior Indebtedness or from any trustee thereof; and
before the receipt of any such written notice, the Trustee, subject to the
provisions of Section 9.1 of the Indenture, shall be entitled in all respects to
assume that no such facts exist; provided that if on a date not fewer than one
Business Day prior to the date upon which by the terms hereof any such monies
may become payable for any purpose (including, without limitation, the payment
of the principal of, or premium, if any, or interest on any Security) the
Trustee shall not have received, with respect to such monies, the notice
provided for in this Section 4.5, then, anything herein contained to the
contrary notwithstanding, the Trustee shall have full power and authority to
receive such monies and to apply the same to the purpose for which they were

                                       9
<PAGE>

received, and shall not be affected by any notice to the contrary which may be
received by it on or after such prior date.

        The Trustee, subject to the provisions of Section 9.1 of the Indenture,
shall be entitled to rely on the delivery to it of a written notice by a
Representative or a person representing himself to be a holder of Parent Senior
Indebtedness (or a trustee on behalf of such holder) to establish that such
notice has been given by a Representative or a holder of Parent Senior
Indebtedness or a trustee on behalf of any such holder or holders. In the event
that the Trustee determines in good faith that further evidence is required with
respect to the right of any person as a holder of Parent Senior Indebtedness to
participate in any payment or distribution pursuant to this Article IV, the
Trustee may request such Person to furnish evidence to the reasonable
satisfaction of the Trustee as to the amount of Parent Senior Indebtedness held
by such Person, the extent to which such Person is entitled to participate in
such payment or distribution and any other facts pertinent to the rights of such
Person under this Article IV, and if such evidence is not furnished the Trustee
may defer any payment to such Person pending judicial determination as to the
right of such Person to receive such payment.

4.6 Trustee's Relationship to Parent Senior Indebtedness. The Trustee in its
individual capacity shall be entitled to all the rights set forth in this
Article IV in respect of any Parent Senior Indebtedness at any time held by it,
to the same extent as any other holder of Parent Senior Indebtedness, and
nothing in Section 9.11 of the Indenture or elsewhere in the Indenture, as
amended and supplemented by this First Supplemental Indenture, shall deprive the
Trustee of any of its rights as such holder.

        With respect to the holders of Parent Senior Indebtedness, the Trustee
undertakes to perform or to observe only such of its covenants and obligations
as are specifically set forth in this Article IV, and no implied covenants or
obligations with respect to the holders of Parent Senior Indebtedness shall be
read into the Indenture, as amended and supplemented by this First Supplemental
Indenture, against the Trustee. The Trustee shall not be deemed to owe any
fiduciary duty to the holders of Parent Senior Indebtedness and, subject to the
provisions of Section 9.1 of the Indenture, the Trustee shall not be liable to
any holder of Parent Senior Indebtedness if it shall pay over or deliver to
Holders of Securities, Parent, the Company or any other person money or assets
to which any holder of Parent Senior Indebtedness shall be entitled by virtue of
this Article IV or otherwise.

4.7 No Impairment of Subordination. No right of any present or future holder of
any Parent Senior Indebtedness to enforce subordination as herein provided shall
at any time in any way be prejudiced or impaired by any act or failure to act on
the part of Parent or by any act or failure to act, in good faith, by any such
holder, or by any noncompliance by Parent with the terms, provisions and
covenants of the Indenture, as amended and supplemented by this First
Supplemental Indenture, regardless of any knowledge thereof which any such
holder may have or otherwise be charged with.

                                       10

4.8 Certain Conversions Deemed Payment. For the purposes of this Article IV
only, (1) the issuance and delivery of junior securities upon conversion of
Securities in accordance with Article 4 of the Indenture, as amended and
supplemented by this First Supplemental Indenture, shall not be deemed to
constitute a payment or distribution on account of the principal of (or premium,
if any) or interest on Securities or on account of the purchase or other
acquisition of Securities, and (2) the payment, issuance or delivery of cash
(except in satisfaction of fractional shares pursuant to Section 4.3 of the
Indenture, as amended and supplemented by this First Supplemental Indenture),
property or securities (other than junior securities) upon conversion of a
Security shall be deemed to constitute payment on account of the principal of
such Security. For the purposes of this Section 4.8, the term "junior
securities" means (a) shares of any stock of any class of Parent, or (b)
securities of Parent which are subordinated in right of payment to all Parent
Senior Indebtedness which may be outstanding at the time of issuance or delivery
of such securities to substantially the same extent as, or to a greater extent
than, the Securities are so subordinated as provided in this Article IV. Nothing
contained in this Article IV or elsewhere in this First Supplemental Indenture,
the Indenture or in the Securities is intended to or shall impair, as among
Parent, its creditors other than holders of Parent Senior Indebtedness and the
Holders, the right, which is absolute and unconditional, of the Holder of any
Security to convert such Security in accordance with Article 4 of the Indenture,
as amended and supplemented by this First Supplemental Indenture.

4.9 Article Applicable to Paying Agents. If at any time any Paying Agent other
than the Trustee shall have been appointed by the Company and be then acting
under the Indenture, the term "Trustee" as used in this Article IV shall (unless
the context otherwise requires) be construed as extending to and including such
Paying Agent within its meaning as fully for all intents and purposes as if such
Paying Agent were named in this Article IV in addition to or in place of the
Trustee; provided, however, that the first paragraph of Section 4.5 of this
First Supplemental Indenture shall not apply to Parent or any Affiliate of
Parent if it or such Affiliate acts as Paying Agent.

4.10 Parent Senior Indebtedness Entitled to Rely. The holders of Parent Senior
Indebtedness (including, without limitation, Designated Parent Senior
Indebtedness) shall have the right to rely upon this Article IV, and no
amendment or modification of the provisions contained herein shall diminish the
rights of such holders unless such holders shall have agreed in writing thereto.

                                  V. AMENDMENTS

        and any shares of any class or classes of capital stock of Parent
        resulting from any reclassification or reclassifications thereof and
        which have no preference in respect of dividends or of amounts payable
        in the event of any voluntary or involuntary liquidation, dissolution or
        winding-up of Parent and which are not subject to redemption by Parent;
        provided, however, that if at any time there shall be more than one such
        resulting class, the shares of each such class then so issuable shall be
        substantially in the proportion which the total number of shares of such
        class resulting from all such reclassifications bears to the total
        number of shares of all such classes resulting from all such
        reclassifications.

        (c) the definition of "Designated Parent Senior Indebtedness" is hereby
added to Section 1.1 in its alphabetical location:

        "Designated Parent Senior Indebtedness" means any particular Parent
        Senior Indebtedness in which the instrument creating or evidencing the
        same or the assumption or guarantee thereof (or related agreements or
        documents to which Parent is a party) expressly provides that such
        Parent Senior Indebtedness shall be "Designated Parent Senior
        Indebtedness" for purposes of this Indenture (provided that such
        instrument, agreement or other document may place limitations and
        conditions on the right of such Parent Senior Indebtedness to exercise
        the rights of Designated Parent Senior Indebtedness). If any payment
        made to any holder of any Designated Parent Senior Indebtedness or its
        Representative with respect to such Designated Parent Senior
        Indebtedness is rescinded or must otherwise be

                                       12
<PAGE>

        returned by such holder or Representative upon the insolvency,
        bankruptcy or reorganization of the Parent or otherwise, the reinstated
        Indebtedness of the Parent arising as a result of such rescission or
        return shall constitute Designated Parent Senior Indebtedness effective
        as of the date of such rescission or return.

        (d) the following definition is hereby added to Section 1.1 in its
alphabetical location:

               "First Supplemental Indenture" means the First Supplemental

        successor replaces it pursuant to this Indenture, and thereafter means
        the successor.

        (g) the definition of "Parent Senior Indebtedness" is hereby added to
Section 1.1 in its alphabetical location:

               "Parent Senior Indebtedness" means the principal of, premium, if
        any, interest (including all interest accruing subsequent to the
        commencement of any bankruptcy or similar proceeding, whether or not a
        claim for post-petition interest is allowable as a claim in any such
        proceeding) and rent payable on or in connection with, and all fees,
        costs, expenses and other amounts accrued or due on or in connection
        with, Indebtedness of Parent, whether outstanding on the date of the
        First Supplemental Indenture or thereafter created, incurred, assumed,
        guaranteed or in effect guaranteed by Parent (including all deferrals,
        renewals, extensions or refundings of, or amendments, modifications or
        supplements to, the foregoing), unless in the case of any particular
        Indebtedness the instrument creating or evidencing the same or the
        assumption or guarantee thereof expressly provides that such
        Indebtedness shall not be senior in right of payment to the Securities
        or expressly provides that such Indebtedness is "pari passu" or "junior"
        to the Securities. Notwithstanding the foregoing, the term Parent Senior
        Indebtedness shall not include (i) any Indebtedness of Parent to any
        Subsidiary of Parent, (ii) the obligations of Parent under Article III
        of this First Supplemental Indenture, and (iii) the Securities. If any
        payment made to any holder of any Parent Senior Indebtedness or its
        Representative with respect to such Parent Senior Indebtedness is
        rescinded or must otherwise be returned by such holder or Representative
        upon the insolvency, bankruptcy or reorganization of Parent or
        otherwise, the reinstated Indebtedness of Parent arising as a result of
        such

                                       13
<PAGE>

        rescission or return shall constitute Parent Senior Indebtedness
        effective as of the date of such rescission or return.

        (h) the definition of "Senior Indebtedness" is hereby amended by
deleting the second sentence thereof and replacing it with "Notwithstanding the
foregoing, the term Senior Indebtedness shall not include (i) any Indebtedness
of the Company to Parent, to any Subsidiary of the Company or to any Subsidiary
of Parent, or (ii) the Securities".

        (i) the definition of "Vice President" is hereby amended by inserting
the word "or Parent" immediately after the words "the Company".

5.4 Change in Control. The definition of a "Change in Control" set forth in
Section 3.8(a) is hereby replaced in its entirety by the following:

        "A "Change in Control" shall be deemed to have occurred if any of the
following occurs after the date hereof:

               (1) any "person" or "group" (as such terms are defined below)
other than Parent is or becomes the "beneficial owner" (as defined below),
directly or indirectly, of shares of Voting Stock of Parent or the Company
representing 50% or more of the total voting power of all outstanding classes of
Voting Stock of Parent or the Company, as applicable, or has the power, directly
or indirectly, to elect a majority of the members of the Board of Directors or
the board of directors of the Company, as applicable; or

               (2) the Company or Parent consolidates with, or merges with or
into, another Person (other than a merger of the Company with and into Parent)
or the Company or Parent, sells, assigns, conveys, transfers, leases or
otherwise disposes of all or substantially all of the assets of the Company or
Parent, respectively, or any Person consolidates with, or merges with or into,
the Company or Parent (other than a merger of the Company with and into Parent),
in any such event other than pursuant to a transaction in which the Persons that
"beneficially owned" (as defined below), directly or indirectly, shares of
Voting Stock of the Company or Parent, as the case may be, immediately prior to
such transaction "beneficially own" (as defined below), directly or indirectly,
shares of Voting Stock of the Company or Parent, as the case may be,
representing at least a majority of the total voting power of all outstanding
classes of Voting Stock of the surviving or transferee Person; or

               (3) the holders of capital stock of the Company or Parent approve
any plan or proposal for the liquidation or dissolution of the Company or
Parent, respectively, (whether or not otherwise in compliance with the terms
hereof).

For the purpose of the definition of "Change in Control", (i) "person" and
"group" have the meanings given such terms under Section 13(d) and 14(d) of the
Exchange Act or any successor provision to either of the foregoing, and the term
"group" includes any group acting for the purpose of acquiring, holding or
disposing of securities within the meaning of Rule 13d-5(b)(1) under the
Exchange Act (or any successor provision thereto), (ii) a "beneficial owner"
shall be determined in accordance with Rule 13d-3 under the

                                       14
<PAGE>

Exchange Act, as in effect on the date of this Indenture, except that the number
of shares of Voting Stock of the Company or Parent shall be deemed to include,
in addition to all outstanding shares of Voting Stock of the Company or Parent,
respectively, and Unissued Shares deemed to be held by the "person" or "group"
(as such terms are defined above) or other Person with respect to which the
Change in Control determination is being made, all Unissued Shares deemed to be
held by all other Persons, and (iii) the terms "beneficially owned" and
"beneficially own" shall have meanings correlative to that of "beneficial
owner". The term "Unissued Shares" means shares of Voting Stock not outstanding
that are subject to options, warrants, rights to purchase or conversion
privileges exercisable within 60 days of the date of determination of a Change
in Control.

        Notwithstanding anything to the contrary set forth in this Section 3.8,
a Change in Control will not be deemed to have occurred if either:

        (1) the Closing Price (determined in accordance with Section 4.6(d) of
this Indenture) of the Common Stock for any five Trading Days during the ten
Trading Days immediately preceding the Change in Control is at least equal to
105% of the Conversion Price in effect on such Trading Day; or

        (2) in the case of a merger or consolidation, at least 90% of the
consideration (excluding cash payments for fractional shares and cash payments
pursuant to dissenters' appraisal rights) in the merger or consolidation
constituting the Change in Control consists of common stock traded on a United
States national securities exchange or quoted on the Nasdaq National Market (or
which will be so traded or quoted when issued or exchanged in connection with
such Change in Control) and as a result of such transaction or transactions the
securities become convertible solely into such common stock."

5.5 Conversion.

        (a) In the second paragraph of Section 4.2, Section 4.3, Section 4.5,
subsections (a) through (e) of Section 4.6, and Sections 4.7 through 4.9 of the
Indenture, the each instance of word(s) "Company" or, if applicable "the

<PAGE>

        (e) Section 4.12 of the Indenture is hereby amended by deleting in their
